“Cittadinanza è parola antica, segno di un sapere strutturato nell’arco di una lunga tradizione che, tuttavia, non cessa di essere soggetta a numerosi quanto recenti ripensamenti. All’interno dell’ordinamento giuridico statale, infatti, il suo carattere fondativo – quale presupposto per il riconoscimento di diritti – è posto in crisi per la presenza di diversi fattori, ora interni al sistema, ora di natura sovranazionale. Il volume, dalla prospettiva dichiaratamente interdisciplinare, si propone di offrire una panoramica dei molti contesti in cui la cittadinanza vede mutare i suoi significati più tradizionali e di contribuire alla discussione scientifica sulle possibilità innovative che si possono comunque raggiungere in tali trasformazioni. Dai nessi tra ordine economico-sociale e ordine giuridico-politico alla dimensione europea della soggettività giuridica; dalla disciplina dell’immigrazione alle politiche pubbliche fondate sulla residenzialità; dai modi della partecipazione attiva del cittadino alla cosa pubblica ai problemi definitori e istituzionali affrontati dagli studi di genere: i saggi qui riuniti testimoniano l’interesse della Facoltà trentina per gli importanti e trasversali orizzonti di ricerca che il dibattito sulla cittadinanza rilancia e rinnova con particolare urgenza”.

Conversational Agent for Health Coaching

Poor diet and physical inactivity are two of the biggest healthcare challenges we are facing, and are related to individuals lifestyle. In fact, a poor lifestyle is strongly correlated to chronic diseases, the leading causes for morbidity and mortality. Adhering to a healthy diet and following an active lifestyle are thus necessary to promote the overall health. However, maintaining a healthy diet and physically active lifestyle is hard. This is due to poor health literacy, lack of awareness, motivation and effective intervention support. Recent years have seen a blast of mHealth apps for health promotion, targeting in particular dietary behavior change. However, reviews showed difficulties in effective adoption and use of these applications in long-term health promotion. Contemporary approaches have focused on tracking user condition and few have analyzed aspects of user interaction with the system. To promote individuals health, users can benefit from some form of tailored guidance or coaching. That said, to ensure adequate users support, personalized care with a human agent in the loop can enhance the care delivery. Due to the increasing demand for continuous care by users and the shortage of caregiver resources, current health services are inefficient relative to user support and decreasing caregivers workload. Digital health devices can act as a key player in providing interactive health activities (via mobile and telemedicine systems), enhancing self-monitoring (through wearable tracker) and tailored coaching (using either automated or manual coaching systems). However, they’re ineffective in providing continuous health services and creating a balance between users support and caregivers workload. In addition, even with the technology existence, there is low motivation to maintain a healthy diet or exercise routines. Individuals use messaging applications as part of their regular daily routines. We harness the power of messaging chatbot systems to provide behavior change interventions for healthy lifestyle promotion. We particularly introduce the role of chatbot in task automation and adhering users to a health plan. Thus, in this thesis we present the concept of "Conversational User Interface in Health Coaching Interventions" that consists of a just-in-time health services to users and caregivers. We discuss ways to integrate the chatbot to assist caregivers with their tasks and support users with their condition. We get users to cue themselves to action by attaching the chatbot with users’ daily messaging routines. The service will eliminate the technology barrier and impairment for the users i.e., elderly. The chatbot accesses reliable user compliance data, sets adherence reminders by condition, and reports daily individuals adherence. The chatbot alerts the coach through a web application in critical cases. The approach facilitates adherence to health interventions by investigating a human-virtual agent mediated coaching approach on user motivation to adhere to the health promotion plan. The approach was validated with different experimentation phases. Using multiple research methods, this dissertation has made several contributions to the understanding of user motivation and the role of a semi-automated system with a human and virtual agent in tracking individuals with poor lifestyle. We will discuss the main contributions and experimentation results throughout the thesis.

The aim of the paper is to study the characteristics of different 3D digital models (point clouds, mesh, CSG, BIM) for the realization of a museum of historical buildings widespread in the territory of South Tyrol through the 3D modeling of several farmhouses between the towns of Collalbo, Longomoso and Siffiano, in the Renon area. Therefore, moving from a defined case study, the paper proposes a workflow for model choice, use, and sharing considering also users profile.The objective is to create a system that allows, the sharing, both on site and remotely, of farmhouses digital models, information, images and documents found during the research. The purpose is to enhance the territory with the promotion of its knowledge taking into account also the importance of the participative aspects. In fact, in this system, are crucial and are a fundamental part of the safeguarding process, effectively increasing the information content and filling any information gaps, allowing the system to grow and become increasingly considerable and effective for the knowledge, documentation and enhancement of the territory.

We are interested in aligning how people think about objects and what machines perceive, meaning by this the fact that object recognition, as performed by a machine, should follow a process which resembles that followed by humans when thinking of an object associated with a certain concept. The ultimate goal is to build systems which can meaningfully interact with their users, describing what they perceive in the users' own terms. As from the field of Lexical Semantics, humans organize the meaning of words in hierarchies where the meaning of, e.g., a noun, is defined in terms of the meaning of a more general noun, its genus, and of one or more differentiating properties, its differentia. The main tenet of this paper is that object recognition should implement a hierarchical process which follows the hierarchical semantic structure used to define the meaning of words. We achieve this goal by implementing an algorithm which, for any object, recursively recognizes its visual genus and its visual differentia. In other words, the recognition of an object is decomposed in a sequence of steps where the locally relevant visual features are recognized. This paper presents the algorithm and a first evaluation.

Migrant Remittances and Masculinity: Between Desire and Double Discredit
Ester Gallo
Reena Kukreja
Gallo, Ester
This chapter explores the relation between international mobility, masculinity, and remittances in the context of migrant men who are employed as paid care providers within Italian families. Specifically, the analysis addresses the question of how men who emigrate by following their wives negotiate remittances within marriage and of what this reveals about their subaltern class location. Remittances are here understood as a transnational social practice that is informed by gendered community expectations and by migration trajectories and family-cycle. The analysis contributes to the burgeoning debate on the remittance-gender nexus by addressing the understudied relation between migrant men, masculinities and transnational transactions. The analysis suggests how migrant men experience a double discredit. One generated by the inversion of the dominant male-centred migration pathway, while the other addresses migrant men’s downward mobility and gendered racialisation as feminised domestic workers, who are expected by their in-laws networks and employers to prove their deservingness as supportive husband and trustworthy labourers. This double discredit informs migrant men’s im-mobility and dependency experience in Kerala and Italy. It brings them to redefine their roles within transnational households as husbands and to search for a balance between, on the one hand, expectations emerging from renewed kinship and gender hierarchies and, on the other, personal desires for autonomy and marital love.

Cyber-physical Systems of Systems (SoSs) are large-scale systems made of independent and autonomous cyber-physical Constituent Systems (CSs) which may interoperate to achieve high-level goals also with the intervention of humans. Providing security in such SoSs means, among other features, forecasting and anticipating evolving SoS functionalities, ultimately identifying possible detrimental phenomena that may result from the interactions of CSs and humans. Such phenomena, usually called emergent phenomena, are often complex and difficult to capture: the first appearance of an emergent phenomenon in a cyber-physical SoS is often a surprise to the observers. Adequate support to understand emergent phenomena will assist in reducing both the likelihood of design or operational flaws, and the time needed to analyze the relations amongst the CSs, which always has a key economic significance. This paper presents a threat analysis methodology and a supporting tool aimed at i) identifying (emerging) threats in evolving SoSs, ii) reducing the cognitive load required to understand an SoS and the relations among CSs, and iii) facilitating SoS risk management by proposing mitigation strategies for SoS administrators. The proposed methodology, as well as the tool, is empirically validated on Smart Grid case studies by submitting questionnaires to a user base composed of 3 stakeholders and 18 BSc and MSc students.

Some recent results in linear scalar quantum field theory in globally hyperbolic asymptotically flat spacetimes
Moretti, Valter
Moretti, Valter
This work concerns some recent results obtained by the author and collaborators about QFT in asymptotically flat spacetimes at infinity. In particular it is shown that bosonic QFT can be defined on the boundary =+ of any asymptotically flat spacetime M. This theory admits a state which is uniquely determined from invariance under BMS group and a BMS-energy positivity requirement. There is a nice interplay with bosonic (massless, conformally coupled) QFT defined in the bulk spacetime. In particular, under suitable further requirements, the universal state induces in the bulk spacetime M a state, M, which enjoys the following remarkable properties. It reduces to standard Minkowski vacuum whenever M is Minkowski spacetime and in the general case, it is invariant under the group of isometries of the spacetime M, it is a ground state (i.e. it satisfies the positive energy condition) with respect to any timelike Killing time of M without zero-modes, finally M enjoys the global Hadamard property so that it is suitable for locally covariant perturbative renormalization procedures.

Economic Growth and Public Debt: Beyond Debt-Thresholds. Theoretical and Empirical Issues.

The idea that public debt may represent a burden for the economic system as a whole has distant origins and focuses on who and how should pay for debt, and with what consequences on the economy. Nevertheless, particularly influential both for academic research and the implementation of the fiscal corrective policies was the empirical paper proposed by Reinhart and Rogoff in 2010 at the dawn of the crisis. Reinhart and Rogoff (2010), in a large panel of countries, identified a critical threshold of 90% of the debt-to-GDP ratio beyond which debt is harmful to growth. Several countries in the world were fast approaching that threshold or already were well beyond it. Though Reinhart and Rogoff’s work was affected by many flaws, it has spurred buoyant empirical research in search of the general debt thresholds above which growth is jeopardised by public debt. Further works have supported the existence of critical debt-to-GDP ratios under various time and space observational fields, but results of these researches are inconclusive or controversial, as discussed in Chapter 2. Country-specific characteristics and contingencies play in fact a prominent role, thus prompting a branch of literature that attempts to comprehensively understand the debt-growth relationship and its determinants (see for instance Panizza and Presbitero, 2014; Eberhardt and Presbitero, 2015). In contrast with the findings of the broad threshold literature and of many theoretical models, the idea that public debt is always harmful to economic growth has partially been reconsidered in the last few years. Nevertheless, the existence of a linkage between debt and growth has not been rejected: the long-run relationship between such macroeconomic variables is inevitably and broadly affected by heterogeneous factors. However, in retrospect and as emerges in Chapter 1, one may say that the empirical pursuit of the debt-to-GDP threshold harmful to growth lacks deeper foundational work: why should we expect a negative public debt-growth relationship? In addition, if such a relationship exists, why should it take the specific form of a threshold of the debt-to-GDP ratio, and why should we expect this threshold to be equally valid across time and space? These questions are the starting point of this Doctoral Thesis, which is organised as follows. Chapter 1 surveys the theoretical literature concerning public debt and economic growth, aiming at finding a theoretical foundation for the debt-threshold literature. Overall, there is no clear and straightforward answer to the questions of why we should expect a negative public debt-growth relationship in the first place, why it should take the specific form of a threshold of the debt-to-GDP ratio, and why we should expect this threshold to be equally valid across time and space. Or, from another perspective, there are many possible answers and many elements affecting them, thus reflecting the complexity of the argument, as well as the variety of the empirical situations. In particular, the literature that I examine, on the one hand offers a rich variety of explanations and insights to researchers of the debt-growth relationship but, on the other, it does not provide any one-way conclusion: the relationship may be negative, positive, or even no relationship may exist, both from a theoretical and an empirical point of view. Even less is theoretically founded the existence of a general debt-to-GDP threshold above which growth is consistently stifled. Each country’s specific characteristics, circumstances, and events have an overwhelming importance that cannot be encapsulated in a single general law. In Chapter 1, I also present a fiscal model of endogenous growth that may help address the theoretical issues in an orderly and consistent manner along two specific coordinates of debt assessment: sustainability/unsustainability, and efficiency/inefficiency. The thrust of the model is that no meaningful assessment of debt and its effect on growth at any point in time is possible without reference to the whole debt trajectory and the specific state of the economy along the trajectory. Chapter 2 reviews the empirical literature and focuses on the debt-growth relationship from an econometric point of view. As before, it is difficult to derive a univocal conclusion on the nature of such a relationship on the basis of the literature’s findings: the existence of a significant negative relationship between debt and growth is the predominant thinking, though in contrast with the conclusions of several works. For these reasons, the aim of Chapter 2 is to go to the roots of the debt-growth relationship, to investigate whether the outstanding debt and the GDP are linked. To this end, I have adopted a research methodology that differs from the most common employed in the literature on debt-to-GDP thresholds. First, my analysis does not hinge on any specific theory, and it should not be considered as a proof of a specific theoretical statement. Rather, it is based on the approach outlined by Hoover et al. (2008) and aims at understanding "what the data say" without imposing aprioristic theoretical structures. A second methodological choice consistent with this approach is to treat the (growth of the) amount of public debt and (the growth of) GDP as the two genuine primitives, without imposing the debt-to-GDP ratio as a primitive itself. In fact, for this to be possible, the two underlying primitives should display well defend statistical properties, namely cointegration and convergence towards a long-term equilibrium value, which are usually not tested in the literature. Third, I believe that the heterogeneity, or non-generality, of results that I have pointed out before should be taken as an intrinsic feature of the problem at hand, so that a viable strategy is to restrict, rather than expand, the observational field. I have set time and space limits to my dataset by purpose: my analysis is based on a panel dataset including quarterly data for 25 Eastern and Western European countries from 1999Q1 to 2015Q4. The Eurozone represents a unique "field experiment" of a large number of countries where some key conditioning factors of fiscal policy are common and exogenous, namely fiscal targets and rules, monetary policy, and the exchange rate with the rest of the world. The main result is that a long-run equilibrium relationship between GDP and debt exists for some countries ? and debt and GDP tend to adjust towards it ? but it is not generalisable. Where a relationship exists, it does not always imply that the debt-to-GDP ratio may be the appropriate variable for describing it. Moreover, cross-country heterogeneity and the role of the financial crisis and of the austerity periods remain substantial and overwhelming factors. Therefore, a unique equation describing the GDP-debt relationship does not seem to exist, which entails the impossibility to derive a meaningful general debt-to-GDP threshold. Thus far I have focused on the general relationship between debt and growth from both the theoretical and the empirical points of view. Turning to the analysis of the Sovereign Debt Crisis and of the austerity period, Chapter 3 attempts to explain what has driven austerity ? measured as the first difference of the cyclically adjusted structural primary balance ? within a dataset of 28 European countries. In the first part of this chapter I present a correlation analysis that describes the relationship between the variable austerity and each of the considered determinants, that are brought back to four main sets of variables: fiscal discipline, market discipline, fiscal consolidation, and macroeconomic stabilisation. The second part implements a panel econometric analysis based on the principal component factor analysis and on the pooled partial common correlation effect estimator. Results show that the variables and factors of the analysis are not able to fully explain austerity, though an important contribution is provided by the enforcement of the Eurozone fiscal rules (the adoption of excessive deficit procedures) and is partially counterbalanced by the cyclical position of the economy. The last chapter, Chapter 4, aims at gaining insight into the role of debt and government expectations and their impact on growth under uncertainty conditions. In fact, it is possible that the effects of austerity measures in some countries, for instance the so-called PIIGS, were amplified by uncertainty. My ambition is to relate austerity with consumers’ expectations, thus studying whether and when consumers’ beliefs about public debt and government intervention affect their consumption, savings, and tax compliance choices with a direct impact, at the aggregate level, on economic growth. Therefore, Chapter 4 implements a laboratory experiment to study how people react in a generalized framework in which public debt may be unexpectedly reduced. The debt dynamics arises endogenously: within a public good game, taxes are collected from all participants and are used to cover a given level of public expenditure, which is then equally distributed to the same participants at the beginning of each round. If the collected amount of taxes is lower than what the public expenditure would require, a deficit is generated. Moreover, reproducing a forced withdrawal, the outstanding amount of public debt can be reduced upon accessing subjects’ savings. Within this setting, expectations are directly elicited by asking subjects if they believe that public debt is going to be reduced, and if they think that the other subjects believe that public debt is sustainable. Therefore, it is possible to identify whether and how agents’ allocations and expectations are affected by the public debt path. As mentioned above, a peculiarity of my approach is the endogenous dynamics of public debt: not only it avoids introducing predetermined dynamics, but also increases the ecological validity of the experiment. Participants are indeed more psychologically involved in the debt mechanism and they might feel responsible for the raise in debt. On the other hand, an exogenous dynamics could depict public debt and tax compliance as irrelevant. Results show that this experimental framework is characterized by relatively high and often increasing aggregate savings and relatively low and decreasing aggregate consumption. Interestingly, an increase in the debt-reduction expectations and a decrease in the perceived debt sustainability are also found to explain savings and consumption behaviours, as is shown in the econometric part of Chapter 4.

Structures belonging to the same type and built in the same period may share similar geometrical and spatial characteristics. When these features also affect the seismic response of the buildings, they are referred to as typical seismic vulnerabilities. When a building presents one or more of these typical vulnerabilities, some general and qualitative considerations on its seismic behaviour can be made a priori, considering their actual influence on the seismic behaviour of other similar cases. In this work, we propose and apply a specific procedure based on a priori considerations to a specific building type: the post-World War II Italian Schools. To this purpose, we first improved our knowledge about this type of building, pointing out typical and specific seismic vulnerabilities by studying the standard architectural principles suggested by the main manuals and laws of that time. Then, in order to find how these typological features affect the global seismic behaviour of the examined structures, we analysed a real case study representative of the entire building type. Pushover and Nonlinear Dynamic analyses have been carried out, considering four different models, representing three different configurations that may result from different combinations of the most significant typical vulnerabilities.

The diffusion of digital technologies triggered a radical departure from previous modalities of cultural transmission but, at the same time, general characteristics of human cultural evolution and cognition influence these developments. In this chapter, I will explore some areas where the contacts between cultural evolution research and digital media seem more promising. As cultural evolution-inspired research on internet phenomena is still limited, these areas represent suggestions and links with works in other disciplines more than reviews of past research in cultural evolution. These include topics such as how to conceptualise social influence online and how information spreads in social media; how digital media could enhance cumulative culture; and the differences between online and offline cultural transmission. I will then briefly consider possible future directions: the influence of different affordances in different media supporting cultural transmission; the role of producers of cultural traits; and, finally, the effects on cultural dynamics of algorithms selecting information.

This thesis treats mathematical models for host-parasitoid interactions. It is composed of three parts. In the first part, a class of such models is analyzed theoretically. It focuses on the phenomena of multiple coexistence equilibria of competing parasitoid species. The second part is about a model for determining how a parasitoid release should be timed to optimally control the invasive fruit fly Drosophila suzukii. The third part analyzes an experiment for releasing parasitoids in a greenhouse which is infested by D.suzukii. The models presented are used to discuss how to improve such biological control strategies.

Governments adopt strategies to follow the objective Europe 2020 and focus on the development of Renewable Energy Technologies, RET, to improve the transition of the production of energy from fossil fuels sources to renewable energy sources, RES. More than decades before, the energy transition towards renewable energies emerges as a relevant objective of the European governments. The fluctuating prices of oil and the uncertainty on the future supply of fossil fuels open new challenges for communities to actuate an energy transition towards RES. The RET can afflict deeply the landscape structure and by this point of view the energy transition is one of the most relevant drivers in the landscape change of the last three decades. In several cases energy transition may face opposition from regions and communities because of the change that RET produce in local landscapes and related economic, cultural and ecological functions. This change has been defined as a conflict between the local narrative of the right to the landscape by local communities and the global narrative that aims at a low carbon future. Exploring the relationship between Ecosystem Services (ES) and Renewable Energy (RE), the conflict among a global perspective and a local perspective has been resumed by several authors as a trade-off among provisioning and regulating ES from one side and cultural ES from the other. The overcoming of this conflict can be based on bottom-up processes that enhance the energy transition starting by local organizations of communities that want to reach a self-sufficieny in renewable energy supply. Transition management is possible if we produce innovation at local scale. An ES approach supports the transition management and the envisioning future energy landscapes by offering transparent trade-offs, exposing risks and benefits. If societies produce clean energy it may happen that RET afflict other ES. The main paradigm for the sustainability of a energy landscape is that the introduction of RET should not cause crucial trade-offs among the other ES, this is why this research wants to study this relationship, as several authors have already stressed. By the literature review it is possible to state a general gap of knowledge in integrated approaches in the evaluation of RET, considering diverse RES and ES provided by the landscape and evaluating a trade-off through a participatory process. To fulfill such gap and produce an enhancement of knowledge, this research follows the main objective of introducing a trade-off analysis into a design approach to formulate long-term visions for sustainable energy landscapes. The results we got indicate that it is possible to plan and design with the ES sustainable energy landscape.This process facilitates a sustainable energy transition of communities through a participatory landscape design that reduce the trade-off between the Renewable Energy and the ES supplies.

GEOTOP: A Hydrological Balance Model: Technical Description and Programs Guide,Version 0.75
Bertoldi, Giacomo
Rigon, Riccardo
Bertoldi, Giacomo
Rigon, Riccardo
The study of the hydrologic cycle is physically focused on the analysis of the interactions between the soil surface (and specifically the soil water content, linked with precipitation) and the low atmosphere, which occur mainly through the mediation of the soil itself, the vegetation and the turbulent and radiative energy transfers which take place on the Earth's surface. In recent years, the hydrologic research has evolved towards a comprehensive theory describing the mass, energy and motion-quantity exchanges between surface and atmosphere at several scales. The practical aims of this efforts are: (1) to improve the mid- and long-term hydrologic forecasts; (2) to increase our capability of describing the impacts deriving from changes in the soil use and in the climate on the hydrologic cycle and on the Earth's ecosystems. The paper illustrate the implementation of GEOTOP, a distributed model of the hydrologic cycle which is meant to give a scientific contribution in this direction. GEOTOP is a terrain-based model, i.e. it is based on the employment of DEMs (digital elevation models); it is a distributed model, since all the simulated variables are returned for each pixel in the basin; it is a model of the hydrological cycle, in the sense that it simulates all the elements of the hydrological cycle, and not only the mass balance but also the energy balance: in fact the two balance equations are coupled by the evapotranspiration terms and by the soil temperature, which controls the soil hydraulic conductivity and the snow cover accumulation. As to the soil-atmosphere interaction, GEOTOP follows the treatment initially developed by Deardorf, and then implemented, with numerous changes, in land surface models either at global scale like BATS, NCAR-LSM, NOAH-LSM - or at larger scales like the VIC or at basin sclae like the DHSVM. The model adopts original solutions for the discharge calculation. In particular, it differs from the TOPMODEL, because it does not assume any stationeries conditions in the subsurface flows.

This paper presents the application of a new and promising learning algorithm based on kernel methods, i.e., support vector machines (SVMs), for the control of injection moulding processes and plasticating extrusion. In particular, the main purpose of this work is to assess the effectiveness of the method when applied to such kinds of industrial processes, characterised by a large number of variables and strictly correlated by nonlinear relationships. First, we analyse the injection process by developing a simplified model, then we identify it by using a support vector machine. The reference of the control system is tracked through the design of a control block based on the structure of the SVM.

An extremely compact integrated receiver for differential quadrature phase shift keying signals based on two tunable silicon-on-insulator microring resonators and four integrated germanium photodetectors is reported. Simulations show the expected performance of the device and how it compares with alternative receivers, i.e., conventional receivers based on delayed Mach-Zehnder interferometers and Gaussian filters-based ones. The device, fabricated in a silicon photonic multiuser wafer run, is described and experimentally characterized showing operation for signal ranging from 10 to 20 Gbaud.

Increased circulating sclerostin and accumulation of advanced glycation end-products (AGEs) are two potential mechanisms underlying low bone turnover and increased fracture risk in type 2 diabetes (T2D). Whether the expression of the sclerostin-encoding SOST gene is altered in T2D, and whether it is associated with AGEs accumulation or regulation of other bone formation-related genes is unknown. We hypothesized that AGEs accumulate and SOST gene expression is upregulated in bones from subjects with T2D, leading to downregulation of bone forming genes (RUNX2 and osteocalcin) and impaired bone microarchitecture and strength. We obtained bone tissue from femoral heads of 19 T2D postmenopausal women (mean glycated hemoglobin [HbA1c] 6.5%) and 73 age- and BMI-comparable nondiabetic women undergoing hip replacement surgery. Despite similar bone mineral density (BMD) and biomechanical properties, we found a significantly higher SOST (p =.006) and a parallel lower RUNX2 (p =.025) expression in T2D compared with non-diabetic subjects. Osteocalcin gene expression did not differ between T2D and non-diabetic subjects, as well as circulating osteocalcin and sclerostin levels. We found a 1.5-fold increase in total bone AGEs content in T2D compared with non-diabetic women (364.8 ± 78.2 versus 209.9 ± 34.4 μg quinine/g collagen, respectively; p <.001). AGEs bone content correlated with worse bone microarchitecture, including lower volumetric BMD (r = −0.633; p =.02), BV/TV (r = −0.59; p =.033) and increased trabecular separation/spacing (r = 0.624; p =.023). In conclusion, our data show that even in patients with good glycemic control, T2D affects the expression of genes controlling bone formation (SOST and RUNX2). We also found that accumulation of AGEs is associated with impaired bone microarchitecture. We provide novel insights that may help understand the mechanisms underlying bone fragility in T2D.

Mechanics and numerical simulations of Dry Granular Flows driven by gravity

Settore ICAR/01 - Idraulica
The gravitational granular flows (e.g. debris flows or snow avalanches) are catastrophic and destructive phenomena affecting many areas in the world, and especially the mountain areas of Europe. Proper design criteria are required in order to improve protection structures and prevention strategies. Due to their complex nature, these phenomena present many aspects still unsolved in the research field. This research addresses some aspects of the mechanics of dry granular flows: a 1D depth integrated model has been developed, based on a two phase approach. The system of equations consists of three partial differential equations, derived from the mass balances for the solid and fluid phase and from the momentum balance for the solid phase, and two rheological relations determined through experimental tests and particle numerical simulations. The experimental investigation hes been conducted in a laboratory channel, by recording through high speed cameras the motion of polystyrene spherical particles. Within this research, it has been developed an ad hoc optical method to analyze and process the images recorded, with the aim of defining the main flow characteristics. From a numerical point of view, a path conservative finite volume scheme has been adopted to solve the system of equations previously described: the numerical solution is compared to the experimental results for different configurations, in order to verify the effectiveness of the mode

Service Integration through Structurepreserving Semantic Matching
McNeill, Fiona
Besana, Paolo

Giunchiglia, Fausto
Mcneill, Fiona
Besana, Paolo
Pane, Juan
Giunchiglia, Fausto
The problem of integrating services is becoming increasingly pressing. In large, open environments such as the Semantic Web, huge numbers of services are developed by vast numbers of different users. Imposing strict semantics standards in such an environment is useless; fully predicting in advance which services one will interact with is not always possible as services may be temporarily or permanently unreachable, may be updated or may be superseded by better services. In some situations, characterised by unpredictability, such as the emergency response scenario described in this case, the best solution is to enable decisions about which services to interact with to be made on-the-fly. We propose a method of doing this using matching techniques to map the anticipated call to the input that the service is actually expecting. To be practical, this must be done during run-time. In this case, we present our structurepreserving semantic matching algorithm (SPSM), which performs this matching task both for perfect and approximate matches between calls. In addition, we introduce the OpenKnowledge system for service interaction which, using the SPSM algorithm, along with many other features, facilitates on-the-fly interaction between services in an arbitrarily large network without any global agreements or pre-run-time knowledge of who to interact with or how interactions will proceed. We provide a preliminary evaluation of the SPSM algorithm within the OpenKnowledge framework.

Accounting for immunoprecipitation efficiencies in the statistical analysis of ChIP-seq data

Background: ImmunoPrecipitation (IP) efficiencies may vary largely between different antibodies and between repeated experiments with the same antibody. These differences have a large impact on the quality of ChIP-seq data: a more efficient experiment will necessarily lead to a higher signal to background ratio, and therefore to an apparent larger number of enriched regions, compared to a less efficient experiment. In this paper, we show how IP efficiencies can be explicitly accounted for in the joint statistical modelling of ChIP-seq data.Results: We fit a latent mixture model to eight experiments on two proteins, from two laboratories where different antibodies are used for the two proteins. We use the model parameters to estimate the efficiencies of individual experiments, and find that these are clearly different for the different laboratories, and amongst technical replicates from the same lab. When we account for ChIP efficiency, we find more regions bound in the more efficient experiments than in the less efficient ones, at the same false discovery rate. A priori knowledge of the same number of binding sites across experiments can also be included in the model for a more robust detection of differentially bound regions among two different proteins.Conclusions: We propose a statistical model for the detection of enriched and differentially bound regions from multiple ChIP-seq data sets. The framework that we present accounts explicitly for IP efficiencies in ChIP-seq data, and allows to model jointly, rather than individually, replicates and experiments from different proteins, leading to more robust biological conclusions. © 2013 Bao et al.; licensee BioMed Central Ltd.

Firms and Trade Policy Lobbying in the European Union

Hanegraaff, M
Poletti, A
Van Ommeren, E
Our understanding of the role of firms in the making of European Union (EU) trade policy remains partial. This article contributes to expanding this literature by investigating under what conditions we observe more firm-centric lobbying, compared to business associational lobbying, in EU trade policy. We advance the arguments that firm-centric political lobbying in EU trade policy-making is a function of both industry and country-level characteristics. Relying on an original dataset of lobbying contacts with the EU Trade Commissioner, his or her cabinet members and the Director-General between 2014 and 2018, we find that the likelihood of firm-centric lobbying increases in (1) EU industries displaying high levels of multinational corporations' activity, global sourcing of intermediates and product differentiation and (2) countries characterized as liberal market economies. Besides showing that firm-centric models of trade travel well in the EU context, we contribute to advancing the understanding of how domestic political institutions affect the politics of trade.

Brane-world extra dimensions in light of GW170817

Sunny Vagnozzi
Visinelli, Luca
Bolis, Nadia
Vagnozzi, Sunny
The search for extra dimensions is a challenging endeavor to probe physics beyond the Standard Model. The joint detection of gravitational waves (GW) and electromagnetic (EM) signals from the merging of a binary system of compact objects like neutron stars can help constrain the geometry of extra dimensions beyond our 3 + 1 spacetime ones. A theoretically well-motivated possibility is that our observable Universe is a 3 + 1-dimensional hypersurface, or brane, embedded in a higher 4 + 1-dimensional antide Sitter (AdS(5)) spacetime, in which gravity is the only force which propagates through the infinite bulk space, while other forces are confined to the brane. In these types of brane-world models, GW and EM signals between two points on the brane would, in general, travel different paths. This would result in a time lag between the detection of GW and EM signals emitted simultaneously from the same source. We consider the recent near-simultaneous detection of the GW event GW170817 from the LIGO/Virgo collaboration, and its EM counterpart, the short gamma-ray burst GRB170817A detected by the Fermi Gamma-ray Burst Monitor and the International Gamma-Ray Astrophysics Laboratory Anti-Coincidence Shield spectrometer. Assuming the standard.-cold dark matter scenario and performing a likelihood analysis which takes into account astrophysical uncertainties associated to the measured time lag, we set an upper limit of l less than or similar to 0.535 Mpc at 68% confidence level on the AdS(5) radius of curvature l. Although the bound is not competitive with current Solar System constraints, it is the first time that data from a multimessenger GW-EM measurement is used to constrain extra-dimensional models. Thus, our work provides a proof of principle for the possibility of using multimessenger astronomy for probing the geometry of our space-time.

AbstractThe development of effective drugs to treat coronavirus infections remains a significant challenge for the scientific community. Recent evidence reports on the sigma-1 receptor (S1R) as a key druggable host protein in the SARS-CoV-1 and SARS-CoV-2 interactomes and shows a potent antiviral activity against SARS-CoV-2 for the S1R antagonist PB28. To improve PB28 activity, we designed and tested a series of its analogues and identified a compound that is fourfold more potent against SARS-CoV-2 than PB28 itself. Interestingly, we found no direct correlation between S1R affinity and SARS-CoV-2 antiviral activity. Building on this, we employed comparative induced fit docking and molecular dynamics simulations to gain insights into the possible mechanism that occurs when specific ligand–protein interactions take place and that may be responsible for the observed antiviral activity. Our findings offer a possible explanation for the experimental observations, provide insights into the S1R conformational changes upon ligand binding and lay the foundation for the rational design of new S1R ligands with potent antiviral activity against SARS-CoV-2 and likely other viruses.

: hMT+/V5 is a region in the middle occipitotemporal cortex that responds preferentially to visual motion in sighted people. In cases of early visual deprivation, hMT+/V5 enhances its response to moving sounds. Whether hMT+/V5 contains information about motion directions and whether the functional enhancement observed in the blind is motion specific, or also involves sound source location, remains unsolved. Moreover, the impact of this cross-modal reorganization of hMT+/V5 on the regions typically supporting auditory motion processing, like the human planum temporale (hPT), remains equivocal. We used a combined functional and diffusion-weighted MRI approach and individual in-ear recordings to study the impact of early blindness on the brain networks supporting spatial hearing in male and female humans. Whole-brain univariate analysis revealed that the anterior portion of hMT+/V5 responded to moving sounds in sighted and blind people, while the posterior portion was selective to moving sounds only in blind participants. Multivariate decoding analysis revealed that the presence of motion direction and sound position information was higher in hMT+/V5 and lower in hPT in the blind group. While both groups showed axis-of-motion organization in hMT+/V5 and hPT, this organization was reduced in the hPT of blind people. Diffusion-weighted MRI revealed that the strength of hMT+/V5-hPT connectivity did not differ between groups, whereas the microstructure of the connections was altered by blindness. Our results suggest that the axis-of-motion organization of hMT+/V5 does not depend on visual experience, but that congenital blindness alters the response properties of occipitotemporal networks supporting spatial hearing in the sighted.SIGNIFICANCE STATEMENT Spatial hearing helps living organisms navigate their environment. This is certainly even more true in people born blind. How does blindness affect the brain network supporting auditory motion and sound source location? Our results show that the presence of motion direction and sound position information was higher in hMT+/V5 and lower in human planum temporale in blind relative to sighted people; and that this functional reorganization is accompanied by microstructural (but not macrostructural) alterations in their connections. These findings suggest that blindness alters cross-modal responses between connected areas that share the same computational goals.

This work addresses the issue of controlling a Reconfigurable Intelligent Surface (RIS) in real-time to maximize the network capacity. A RIS control strategy is proposed exploiting a Genetic Algorithm (GA) augmented with learning capabilities to achieve high computation efficiency and guarantee consistent network performance in highly-dynamic scenarios. The proposed strategy does not require knowledge of the channel between the RIS and the users, enabling the design of RIS without channel-sensing hardware. The proposed strategy is demonstrated in a small-scale numerical example.

Dalla Francia a Dresda. Le Bibbie portatili della Sächsische Landesbibliothek - Staats- und Universitätsbibliothek
Paolini, Adriana
Paolini, Adriana
Nell’ambito delle ricerche che stanno progressivamente ‘scoprendo’ la ricchezza del fondo dei manoscritti della Sächsische Landesbibliothek ‒ Staats- und Universitätsbibliothek di Dresda, la lettura delle sezioni dei cataloghi ottocenteschi dedicate ai libri religiosi e liturgici in latino ha permesso di venire a conoscenza della presenza di nove Bibbie di epoca medievale. Queste appartennero alla biblioteca elettorale dei duchi sassoni e furono acquisite per ambizioni da collezionisti e non per interessi dottrinari, come si vedrà. Il saggio si soffermerà su cinque di esse, tutte prodotte nel XIII secolo: i manoscritti Mscr.Dresd.A.134, A.179, A.197, A.201, A.202.

Functional characterization of the RNA binding protein RALY
Moro, Albertomaria
Macchi, Paolo
Moro, Albertomaria
Settore BIO/11 - Biologia Molecolare
Of 25000 genes encoded from genome, more than 90% are subject to alternative splicing or other post-transcriptional modifications. All these events produce a high number of different proteins that form the basis for the high variety of cells. The RNAbinding proteins (RBPs) play crucial roles in this variability by regulating many steps of biological processes regarding RNA metabolism. The heterogeneous nuclear ribonucleoproteins (hnRNPs) belong to big family of RBPs involved in many aspects of RNA metabolism including RNA stability, intracellular transport and translation. More recently, RALY, a RNA-binding protein associated with the lethal yellow mutation in mouse, has been identified as new member of the hnRNP family even if, its biological function remains still elusive.
My PhD project aimed to characterize human RALY and to assess its function in mammalian cells. Initially I dentified the expression pattern of this protein into the cell and I characterized the functional nuclear localization sequence that localizes RALY protein into the nuclear compartment. In order to better understand the role of RALY in the cells, I identified the proteins component of RALY-containing complexes using a new assay named iBioPQ (in vivo-Biotinylation-Pulldown-Quant assay). I also performed polyribosome profiling assay to check the resence of RALY in translating mRNAs. Moreover, a microarray assay was performed in order to identify potential mRNAs whose metabolism appears dependent on RALY expression. Taken together, the results that I obtained suggest that RALY is involved in mRNA metabolism. Unfortunately more studies remain to do before shedding some light on the biological
role of RALY in mammals

Which ESG+F dimension matters most to retail investors? An experimental study on financial decisions and future generations

Klaser, Klaudijo
Bax, Karoline
In this study, we address the ongoing debate about the relative importance of the three dimensions of the ESG framework and whether they are sufficient to capture the full scope of sustainability. We propose a new dimension, the Future Generations pillar (F-pillar), which aims to account for intergenerational equity and sustainability. Our online experiment explores how retail investors make investment decisions when presented with different combinations of financial and ESG information, including the F-pillar. Our findings suggest that retail investors try to balance their financial objectives with sustainability considerations. Moreover, the E-pillar appears to be most relevant when investors adopt a sustainability perspective, while the S-pillar is most relevant when investors consider the financial perspective. Interestingly, our results show that an explicit F-pillar is somewhat redundant, as individuals believe that the three existing ESG pillars already indirectly address the sustainability towards the future generations. This study contributes to the ongoing debate on the relevance of the ESG framework and highlights the need to further explore the interplay between financial and sustainability considerations in retail investment decision-making.

La danza nelle arti figurative tra Ottocento e Avanguardia = Dance in Figurative Arts between Eighteenth Century and Avant-Garde
Vattano, Starlight
Cicalò, E.
Trizio, I.
Vattano, Starlight
From the illustrations of traditional classical dance to the definition of the gestural fascination that subjugated at the beginning of the twentieth century a large number of artists of the figurative avantgarde, poets, writers and sculptors, the article deals with a graphic analysis of the dance representation, its subjects and stage clothes that characterized the way of observing and perceiving the plastic dynamics of the dancers protagonists of numerous drawings,
sketches and sculptures. The graphic corpus of dances and costumes echoes the transformations of the
ballet, so in the images that portray Marie Taglioni and Fanny Elssler the sure handwriting on the sheet gives way to the elusive sign of the body that moves now unpredictable in the theatrical space, as in the set-design subversion made by Gordon Craig, whose images gave body to the essential and backstage backgrounds of the reborn Greek spirituality. In the images portrayed by Plinio Nomellini or Romano Romanelli, Isadora Duncan takes part in the dynamics of nature sculpted by time; the code of the danse d’école extends to a different materiality generated by the possible revelations of the body, going beyond the comforting habit of daily experience in favor of a new structure of dependence between dance and music. Duncan implements this transcription on several areas of reality, proposing
the two arts as sisters, abandoning the idea of the superiority of music over dance, the latter, in the early twentieth century, still conceived as mere popular entertainment. In response to the changed historical and social
conditions, the perception of physical space, like the fragmentary nature of the inner one, restores the need for a return to the model of ancient Greece for an expression of the new. The exploration of the fullbodied archive of images from the past concerns the work of the pioneers of modern dance who merged their gestural imagery with the spiritual act that the body performs in animating statuesque postures inherited from the Hellenic tradition. Thus, together with Duncan, Alexandre and Clotilde Sakharoff, Ruth St. Moritz, Saharet, to name a few, in the early
decades of the twentieth century will participate in a subversion of the dancer image no longer captured by
the precision of the body contour, but characterized by a more anxious and dramatic theatrical attitude
aimed at reaching a Dionysian elsewhere that Isadora formalizes in Der Tanz der Zukunft (the dance of the
future) in which the human being, now inseparable from his/her nature, frees himself/herself from the
corset constraint to wear the silk that allows a glimpse of the flowing forms under the fabric. The dynamic
elements that have defined the transformation of the concept of the body over time, through the figures
increasingly stylized in the sign, become the graphic expedient to observe, recognize and reconstruct the parallel mutations faced by visual language on the basis of the ancient iconographic documentation that inspired the statuesque attitude of the female figure whose free movement becomes manifest in the unstoppable resolve of social emancipation. Draftsmen, directors, set designers and artists will work in close contact with the protagonists of the
dance, who through photographs, sketches and videoframes tell the latest experiments in modern dance, evoking its lights and colors, undergoing the charm and stroke.
Dalle illustrazioni della danza classica di tradizione alla definizione del fascino gestuale che soggiogò all’inizio del XX secolo un gran numero di artisti dell’avanguardia figurativa, di poeti, di scrittori e di scultori, l’articolo affronta un’analisi grafica sulla rappresentazione della danza, dei suoi soggetti e degli abiti di scena che caratterizzarono il modo di osservare e di percepire la dinamica plastica dei danzatori protagonisti di numerosi disegni, bozzetti
e sculture. Il corpus grafico di danze e costumi riecheggia le trasformazioni del balletto, così nelle immagini che ritraggono Marie Taglioni e Fanny Elssler la grafia sicura sul foglio lascia il posto al segno elusivo del corpo che si muove ormai imprevedibile nello spazio teatrale, come nel sovvertimento scenografico operato da Gordon Craig, le cui immagini daranno corpo agli sfondi essenziali e senza quinte della rinata spiritualità greca. Nelle immagini ritratte da Plinio Nomellini o di Romano Romanelli, Isadora Duncan prende parte alla dinamica della natura scolpita dal tempo; il codice della danse d’école si estende a una materialità altra generata dalle rivelazioni possibili del corpo, ltrepassando la confortante abitudine dell’esperienza quotidiana in favore di una nuova struttura di dipendenza tra la danza e la musica. La Duncan attua questa trascrizione su più ambiti del reale, proponendo le due arti come sorelle, abbandonando l’idea della superiorità della musica rispetto alla danza, quest’ultima, ai primi del Novecento, ancora
concepita come mero intrattenimento popolare. In risposta alle mutate condizioni storiche e sociali, la percezione dello spazio fisico, come la frammentarietà di quello interiore, restituisce la necessità di un ritorno al modello della Grecia antica per un’espressione del nuovo. L’esplorazione del corposo archivio di immagini del passato riguarda il lavoro dei pionieri della danza moderna che fonderanno il proprio immaginario gestuale sull’atto spirituale che il corpo compie nell’animare posture statuarie ereditate dalla tradizione ellenica. Così, insieme alla Duncan, Alexandre e Clotilde Sakharoff, Ruth St. Denis, Saharet, per citarne alcuni, nei primi decenni del Novecento parteciperanno a un sovvertimento dell’immagine del danzatore non più catturata dalla precisione del contorno corporeo, ma caratterizzata da un atteggiamento teatrale più ansioso e drammatico teso a raggiungere un altrove dionisiaco che Isadora formalizza nel Der Tanz der Zukunft (la danza del futuro) in cui l’essere umano, ormai inseparabile dalla sua natura, si libera dalla costrizione del corsetto per indossare la seta che lascia intravedere le fluenti forme sotto il tessuto. Gli elementi dinamici che hanno definito la trasformazione del concetto di corpo nel tempo, per mezzo delle figure sempre più stilizzate nel segno, diventano l’espediente grafico per osservare, riconoscere e ricostruire le mutazioni parallelamente affrontate dal linguaggio visuale sulla base della documentazione iconografica antica che ispirò l’atteggiamento statuario della figura femminile il cui movimento libero si fa manifesto dell’inarrestabile risolutezza
di emancipazione sociale. Disegnatori, registi, scenografi e artisti lavoreranno a stretto contatto con i protagonisti della danza che attraverso fotografie, schizzi di scena e fotogrammi raccontano le ultime sperimentazioni della danza moderna, rievocandone luci e colori, subendone il fascino e il tratto.

In this paper, a microwave imaging method for reconstructing two-dimensional dielectric scatterers is presented. Starting from an integral formulation of the electromagnetic scattering phenomena, the method is aimed at determining the dielectric profile of the scatterer under test by means of an innovative particle swarm algorithm. In order to preliminary assess the effectiveness of the proposed method, some numerical experiments are carried out in noiseless as well as in noisy conditions. The obtained results confirm the capabilities of the proposed method in term of reconstruction accuracy and robustness.

L'islamofobia nella letteratura della postmigrazione in Norvegia
Checcucci, Edoardo
Checcucci, Edoardo
In contemporary European societies, which for decades have been going through a process of redefinition as a result of migratory phenomena, Islam-ophobia is certainly one of the conflicts that must be discussed and tackled. The Norwegian postmigration literature, which portrays the life of the “second generation”, provides interesting insights into this problem. If on the one hand there are many cases showing that Islamophobia negatively affects the lives of young Muslims, on the other they express the desire to talk about themselves and to be recognized as full-fledged Norwegian citizens.

L'istruzione in Africa
Cobalti, Antonio
Cobalti, Antonio
Questo lavoro si propone di far conoscere le caratteristiche dell’istruzione nell’Africa subsahariana, una parte del continente con una popolazione di oltre 700 milioni di abitanti divisi in 45 stati. Partendo dall’esame dell’influenza coloniale e delle grandi religioni (Islam e Cristianità) sulla scuola africana, vengono riportati i dati più recenti sulla situazione ai vari livelli di istruzione. Le cause dei bassi livelli di iscrizione trovati vengono discusse, prendendo in esame la crescita demografica, l’infezione HIV/AIDS, la spesa pubblica per l’istruzione, la quantità e la qualità degli insegnanti e il rendimento dell’istruzione. Nell’ultimo paragrafo sono esaminate alcune riforme attuate dai governi africani e caratteristiche generali dello stato in Africa.

To preserve quality features and ensuring availability of fresh fruit on the market, apples need to be stored after
harvest. The low temperature applied during storage, beside avoiding important fruit loss, can also promote the
development of serious chilling injury disorders, such as superficial scald. One of the strategies largely employed
to prevent the development of this phenomenon is the control of the storage atmosphere by lowering down the
oxygen concentration. In this work, a multifaceted survey was carried out to investigate transcriptome variation
together with three categories of metabolites (phenolics, lipids and volatile organic compounds ) in fruit of
‘Granny Smith’ apple cultivar stored in both static and dynamic controlled hypoxia atmosphere for five and seven
months, respectively. The global transcriptome survey identified a core set of differentially expressed genes in
three main functional groups, revealing as the duration of storage had an important effect in the coordination of
gene expression. The effect of the length of storage was furthermore highlighted by the DEG-network analysis
that identified a distinct number and type of transcriptomic hubs. Samples characterized by the development of
superficial scald were distinguished by a higher concentration of chlorogenic acid and a higher expression of
phenylalanine ammonia lyase (PAL) and polyphenol oxidase (PPO) in a time-dependent fashion. The prevention of
this disorder was instead related to distinctive re-programming events, involving the accumulation of specific
antioxidant types of metabolites, very long chain fatty acids (VLCFAs) and the expression of genes coordinating a
hypoxia acclimation process, such as RAP2-like and plant cysteine oxidase (PCO).

Contextualizing employment outcomes in family business research: current findings and future research avenues

Amato, Stefano
Basco, Rodrigo
Lattanzi, Nicola
The empirical evidence of family business phenomenon in terms of employment outcomes is contradictory highlighting the micro–macro gap in the existing research. To address this contradiction, our study disentangles the role of context in family firms’ employment outcomes. To do so, we conduct a systematic literature review of 67 articles focusing on three employment-related outcomes—namely, growth, downsizing, and quality of labour—published in peer-reviewed journals from 1980 to 2020. Based on a two-by-two framework to classify this extant research, we unpack what we know about family firms and employment outcomes and where we can go from here. We highlight three main findings. First, current research is context-less since has mainly focused on the firm level in one context (i.e., region or country) and there is a lack of studies comparing family firms’ employment outcomes in different contexts and explicitly measuring the effects of contextual dimensions on family firms’ employment outcomes. This context-less approach could explain the conflicting results and lack of theoretical predictability about the family effect on employment across contexts. Second, the lack of understanding of the context in which family firms dwell highlights the need for future research to focus on context by theorizing about employment outcomes—that is, measuring context and its interactions with family- and job-related variables. Third, there is a need to further explore, analyse, and theorize on the aggregate effect of family firms on employment outcomes at different level of analysis (e.g., local, regional, and national).

Proposta e sviluppo di nuovi strumenti informali per la didattica e la comunicazione delle Scienze Fisiche

Catalysts are of great importance in many different fields, including the energy and the environmental sectors. It is important to produce them with simple preparation technique and to enhance the catalysts surface-to-volume ratio. The work undertaken in this thesis concerns the synthesis of nanostructures by Pulsed Laser Deposition (PLD) and R.F. sputtering deposition and the tailoring of their structures by varying deposition parameters.
We synthesized Cobalt oxide nanoparticles (NPs) by PLD and
studied the influence of the deposition parameters (i.e. substrate temperature, target-to-substrate distance and partial pressure of Oxygen in the chamber) on the final structure and crystalline phase of the NPs. The deposited NPs can be divided in two main categories: small NPs having a diameter of about 5 nm, and big NPs of size ranging from 50 to 400 nm. Depending on the value chosen for the deposition parameters, small NPs have CoO- or Co3O4 crystalline phase, and NPs can have a core/shell structure. The phase composition of the core and of the shell also vary according to the deposition conditions.
We synthesized thin film of Co-B NPs by PLD. Depending on the energy density, the laser process is able to produce well-dispersed spherical Co NPs partially embedded within B-based film matrix in a single-step deposition. The small size, the polycrystalline nature of Co NPs, and the presence of Boron matrix is important for catalytic performance of the Co-B film. The catalytic activity of the Co-B has been tested in hydrolysis of chemical hydrides (ammonia borane and sodium borohydride). PLD deposition of C-film, to serve as support for Co-B NPs, was performed at different Ar pressures (from 10 to 50 Pa) to tailor film roughness in order to investigate the role of porous and irregular C- surface on supporting Co-B NPs acting as catalysts. The measured hydrogen generation rate attained with C-supported Co-B catalyst film is higher than both unsupported-Co-B film and conventional Co-B powder.
Multilayer ITO/Cr-doped-TiO2 thin films have been synthesized by radiofrequency magnetron sputtering in order to sensitize TiO2 in visible light and to lower the charge recombination rate in the Cr-doped-TiO2. When the multilayer films were exposed to visible light, we observed that the photocurrent increases as function of the number of bilayers by reaching the maximum with 6-bilayers of ITO/Cr-doped- TiO2. The superior photocatalytic efficiency of the 6-bilayers film implies higher hydrogen production rate through water-splitting.
Spontaneous growth of Lead nanowires (NWs) have been observed in composite Al-Pb film deposited by R.F. sputtering deposition. The parameters of deposition and the storage of the Al-Pb films after deposition has been changed in order to understand the growth process of NWs. Evolution of NWs growth was also observed inside a SEM chamber. We propose that a stress-driven mechanism and the corrosion occurring on the films surface in environment atmosphere are the cause of NWs growth.

Superconductivity in intercalated graphite CaC6 and H under extreme pressure is discussed in the framework of superconducting density functional theory. A detailed analysis of how the electron-phonon and electron-electron interactions combine together to determine the superconducting gap and critical temperature (Tc) of these systems is presented. In particular, we discuss the effect on the calculated Tc of the anisotropy of the electron-phonon interaction and of the different approximations for screening the Coulomb repulsion. These results contribute to the understanding of multigap and anisotropic superconductivity, which has received a lot of attention since the discovery of MgB2, and show how it is possible to describe the superconducting properties of real materials on a fully ab initio basis. © 2009 IOP Publishing Ltd.

Towards nonuniform distributions of unisolvent weights for high-order Whitney edge elements

Bruni Bruno, L.
Rapetti, F.
We propose to extend results on the interpolation theory for scalar functions to the case of differential k-forms. More precisely, we consider the interpolation of fields in Pr-Λk(T), the finite element spaces of trimmed polynomial k-forms of arbitrary degree r≥ 1 , from their weights, namely their integrals on k-chains. These integrals have a clear physical interpretation, such as circulations along curves, fluxes across surfaces, densities in volumes, depending on the value of k. In this work, for k= 1 , we rely on the flexibility of the weights with respect to their geometrical support, to study different sets of 1-chains in T for a high order interpolation of differential 1-forms, constructed starting from “good” sets of nodes for a high order multi-variate polynomial representation of scalar fields, namely 0-forms. We analyse the growth of the generalized Lebesgue constant with the degree r and preliminary numerical results for edge elements support the nonuniform choice, in agreement with the well-known nodal case.

Dynamic models of affiliation and the network structure of problem solving in an Open Source Software project

Two-mode networks are used to describe dual patterns of association between distinct social entities through their joint involvement in categories, activities, issues, and events. In empirical organizational research, the analysis of two-mode networks is typically accomplished either by (a) decomposition of the dual structure into its two unimodal components defined in terms of indirect relations between entities of the same kind or (b) direct statistical analysis of individual two-mode dyads. Both strategies are useful, but neither is fully satisfactory. In this article, the authors introduce newly developed stochastic actor-based models for two-mode networks that may be adopted to redress the limitations of current analytical strategies. The authors specify and estimate the model in the context of data they have collected on the dual association between software developers and software problems observed during a complete release cycle of an open source software project. The authors discuss the general methodological implications of the models for organizational research based on the empirical analysis of two-mode networks.

Reasoning about Risk in Agent's Deliberation Process: a Jadex Implementation

Giorgini, Paolo

Autonomous agents and multi-agent systems have been proved to be useful in several safety-critical applications. However, in current agent architectures (particularly BDI architectures) the deliberation process does not include any form of risk analysis. In this paper, we propose guidelines to implement Tropos Goal-Risk reasoning. Our proposal aims at introducing risk reasoning in the deliberation process of a BDI agent so that the overall set of possible plans is evaluated with respect to risk. When the level of risk results too high, agents can consider and introduce additional plans, called treatments, that produce an overall reduction of the risk. Side effects of treatments are also considered as part of the model. To make the discussion more concrete, we illustrate the proposal with a case study on the Unmanned Aerial Vehicle agent.

We present the precision measurements of 11 years of daily cosmic electron fluxes in the rigidity interval from 1.00 to 41.9 GV based on 2.0×10^{8} electrons collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The electron fluxes exhibit variations on multiple timescales. Recurrent electron flux variations with periods of 27 days, 13.5 days, and 9 days are observed. We find that the electron fluxes show distinctly different time variations from the proton fluxes. Remarkably, a hysteresis between the electron flux and the proton flux is observed with a significance of greater than 6σ at rigidities below 8.5 GV. Furthermore, significant structures in the electron-proton hysteresis are observed corresponding to sharp structures in both fluxes. This continuous daily electron data provide unique input to the understanding of the charge sign dependence of cosmic rays over an 11-year solar cycle.

Creative problem-solving is a fundamental skill of human cognition and is conceived as a search process whereby a novel and appropriate solution is generated. However, it is unclear whether children are able to balance novelty and appropriateness to generate
creative solutions and what are the underlying computational mechanisms. Here, we asked children, ranging from 10 to 11 years old, to perform a word association task according to three instructions, which triggered a more appropriate (ordinary), novel (random), or balanced (creative) response. Results revealed that children exhibited greater cognitive flexibility in the creative condition compared to the control conditions, as revealed by the structure and resiliency of the semantic networks. Moreover, responses’ word embeddings extracted from pre-trained deep neural networks showed that semantic distance and category switching index increased in the creative condition with respect to the ordinary condition and decreased compared to the random condition. Critically, we showed how children efficiently solved the exploration/exploitation trade-off to generate creative associations by fitting a computational reinforcement learning (RL) model that simulates semantic search strategies. Our findings provide compelling evidence that children balance novelty and appropriateness to generate creative associations by optimally regulating the level of exploration in the semantic search.
This corroborates previous findings on the adult population and highlights the crucial contribution of both components to the overall creative process. In conclusion, these results shed light on the connections between theoretical concepts such as bottom-up/top-down modes of thinking in creativity research and the exploration/exploitation trade-off in human RL research.

Aerosols are abundant on the Earth and likely played a role in prebiotic chemistry. Aerosol particles coagulate, divide, and sample a wide variety of conditions conducive to synthesis. While much work has centered on the generation of aerosols and their chemistry, little effort has been expended on their fate after settling. Here, using a laboratory model, we show that aqueous aerosols transform into cell-sized protocellular structures upon entry into aqueous solution containing lipid. Such processes provide for a heretofore unexplored pathway for the assembly of the building blocks of life from disparate geochemical regions within cell-like vesicles with a lipid bilayer in a manner that does not lead to dilution. The efficiency of aerosol to vesicle transformation is high with prebiotically plausible lipids, such as decanoic acid and decanol, that were previously shown to be capable of forming growing and dividing vesicles. The high transformation efficiency with 10-carbon lipids in landing solutions is consistent with the surface properties and dynamics of short-chain lipids. Similar processes may be operative today as fatty acids are common constituents of both contemporary aerosols and the sea. Our work highlights a new pathway that may have facilitated the emergence of the Earth’s first cells.

Sensory difficulties represent a crucial issue in the life of autistic individuals. The diagnostic and statistical manual of mental disorders describes both hyper- and hypo-responsiveness to sensory stimulation as a criterion for the diagnosis autism spectrum disorders (ASD). Among the sensory domain affected in ASD, altered responses to tactile stimulation represent the most commonly reported sensory deficits. Although tactile abnormalities have been reported in monogenic cohorts of patients and genetic mouse models of ASD, the underlying mechanisms are still unknown. Traditionally, autism research has focused on the central nervous system as the target to infer the neurobiological bases of such tactile abnormalities. Nonetheless, the peripheral nervous system represents the initial site of processing of sensory information and a potential site of dysfunction in the sensory cascade. Here we investigated the gene expression deregulation in the trigeminal ganglion (which directly receives tactile information from whiskers) in two genetic models of syndromic autism (Shank3b and Cntnap2 mutant mice) at both adult and juvenile ages. We found several neuronal and non-neuronal markers involved in inhibitory, excitatory, neuroinflammatory and sensory neurotransmission to be differentially regulated within the trigeminal ganglia of both adult and juvenile Shank3b and Cntnap2 mutant mice. These results may help in disentangling the multifaced complexity of sensory abnormalities in autism and open avenues for the development of peripherally targeted treatments for tactile sensory deficits exhibited in ASD.

Arbitrating the S8 discrepancy with growth rate measurements from redshift-space distortions
Nunes, Rafael C
Vagnozzi, Sunny
Nunes, Rafael C
Vagnozzi, Sunny
Within the Lambda cold dark matter (ΛCDM) model, measurements from recent cosmic microwave background (CMB) and weak lensing (WL) surveys have uncovered a -3σ disagreement in the inferred value of the parameter S8 ≡ σ8√Ωm/0.3, quantifying the amplitude of late-time matter fluctuations. Before questioning whether the S8 discrepancy calls for new physics, it is important to assess the view of measurements other than CMB and WL ones on the discrepancy. Here, we examine the role of measurements of the growth rate f(z) in arbitrating the S8 discrepancy, considering measurements of fσ8(z) from redshift-space distortions (RSDs). Our baseline analysis combines RSD measurements with geometrical measurements from baryon acoustic oscillations (BAO) and Type Ia Supernovae (SNeIa), given the key role of the latter in constraining Ωm. From this combination and within the ΛCDM model, we find S8 = 0.762-0.025+0030, and quantify the agreement between RSD + BAO + SNeIa and Planck to be at the 2.2σ level: the mild disagreement is therefore compatible with a statistical fluctuation. We discuss combinations of RSD measurements with other data sets, including the EG statistic. This combination increases the discrepancy with Planck, but we deem it significantly less robust. Our earlier results are stable against an extension where we allow the dark energy equation of state w to vary. We conclude that, from the point of view of combined growth rate and geometrical measurements, there are hints, but no strong evidence yet, for the Planck ΛCDM cosmology overpredicting the amplitude of matter fluctuations at redshifts z ≲ 1. From this perspective, it might therefore still be premature to claim the need for new physics from the S8 discrepancy.

Active learning (AL) is one of the popular approaches that can mitigate some of the drawbacks of supervised classification. Although sparse representation classifier (SRC) has already proven to be a robust classifier and successfully used in many applications, it is seldom used jointly with AL. In this letter, we propose a novel AL technique for SRCs. In the proposed model, the query function is designed by combining uncertainty and diversity criteria, both of which are defined by using the SRC in kernel space. The proposed technique outperforms other state-of-the-art methods in terms of classification performance.

Efficient Algorithms for Quantitative Attack Tree Analysis
Carlos E. Budde
Mariëlle Stoelinga
Budde, Carlos E.
Stoelinga, Mariëlle
Numerous analysis methods for quantitative attack tree analysis have been proposed. These algorithms compute relevant security metrics, i.e. performance indicators that quantify how good the security of a system is, such as the most likely attack, the cheapest, or the most damaging one. paper classifies attack trees in two dimensions: proper trees vs. directed acyclic graphs (i.e. with shared subtrees); and static vs. dynamic gates. For each class, we propose novel algorithms that work over a generic attribute domain, encompassing a large number of concrete security metrics defined on the attack tree semantics. We also analyse the computational complexity of our methods.

Crosstalk and BER performance of closely-spaced silicon-on-insulator waveguide arrays
Velha, Philippe

Velha, Philippe
Cerutti, Isabella
Andriolli, Nicola
The high interest for on-chip communications is driven by the possibility to exchange massive amounts of data between different resources (CPUs, GPUs, memories) directly on a system-on-chip. Optical on-chip transmission techniques promise to enhance bandwidth density and transmission reach compared to current electronic solutions.
In this context, mode division multiplexing in integrated optical waveguides has been investigated, but it still suffers from crosstalk and scalability issues. To overcome these problems, super-modes in arrays of closely-spaced waveguides can be exploited, supporting many parallel channels with low crosstalk.
In this paper we consider non-uniform arrays of closely-spaced waveguides in silicon photonics, and experimentally assess the spectral and BER performance of several array designs. Results demonstrate parallel data transmissions at 10 Gb/s over different waveguides with crosstalk <-16 dB and a power penalty <1 dB at BER =1e-9, paving the way for ultra-dense and low-crosstalk on-chip communications.

Purpose
This paper aims to contribute to the scientific debate concerning the impact of equity crowdfunding on the performance of crowdfunded firms after campaigning. To this aim, the purpose of this paper is to investigate the relationship between the characteristics of the campaign and the subsequent firm innovativeness.
Design/methodology/approach
This study adopts a quantitative research approach to evaluate if the entrepreneurial choices affecting the characteristics of the equity crowdfunding campaigns have an impact on the post-campaign firm innovativeness.
Findings
The results of the models show that the campaign characteristics have a direct impact on the firm innovativeness, both in terms of offering and communication and the campaign performance.
Originality/value
This paper presents one of the first studies to investigate the relationship between the choice of campaign characteristics and the post-campaign firm innovativeness. As such, the study contributes to both the literature concerning start-up innovation and the literature about the impact of equity crowdfunding.

Structural behaviour of light-frame timber shear-walls with diagonal board sheathing

Polastri A.
Casagrande, D.
Setti, A.
Polastri, A.
As an alternative to wooden panels, diagonal boards sheathings can be used to provide adequate lateral stability of light-frame timber (LFT) shear-walls. Much more common in the past than the present, LFT shear-walls with diagonal boards (LFT-DB) have undergone a significant revival of use and interest, especially in Europe, due to an increasing attention to adhesive-free engineered wood products and to the development of locally supply chain of wood. The current study aims to establish a better understanding of the behaviour of typical European LFT-DBs through experimental and numerical investigations. Six full-scale shear-wall tests were conducted under monotonic and cyclic load protocols. A finite element numerical model was implemented to study the elastic internal force distribution of boards and wooden frame elements. The results showed that the mechanical behaviour of shear-walls with single layer of boards strongly depends on the lateral load direction. When diagonal boards act in tension, the failure mechanism is primarily related to the yielding of the sheathing-to-framing connections, whereas when diagonal boards act in compression, an early failure of the corner between the outer stud and the top plate is observed. An almost symmetric behaviour of the shear-wall with double-crossed layer was observed in the cyclic test with a failure mode related to the yielding of nails on both faces of the wall.

The brain is the organ most studied using Magnetic Resonance (MR). The emergence of 7T scanners has increased MR imaging resolution to a sub-millimeter level. However, there is a lack of automatic segmentation techniques for 7T MR volumes. This research aims to develop a novel deep learning-based algorithm for on-cloud brain extraction and multi-structure segmentation from unenhanced 7T MR volumes. To this aim, a double-stage 3D U-Net was implemented in a cloud service, directing its first stage to the automatic extraction of the brain and its second stage to the automatic segmentation of the grey matter, basal ganglia, white matter, ventricles, cerebellum, and brain stem. The training was performed on the 90% (the 10% of which served for validation) and the test on the 10% of the Glasgow database. A mean test Dice Similarity Coefficient (DSC) of 96.33% was achieved for the brain class. Mean test DSCs of 90.24%, 87.55%, 93.82%, 85.77%, 91.53%, and 89.95% were achieved for the brain structure classes, respectively. Therefore, the proposed double-stage 3D U-Net is effective in brain extraction and multi-structure segmentation from 7T MR volumes without any preprocessing and training data augmentation strategy while ensuring its machine-independent reproducibility.

Light-Induced Nonthermal Phase Transition to the Topological Crystalline Insulator State in SnSe

Femtosecond pulses have been used to reveal hidden broken symmetry states and induce transitions to metastable states. However, these states are mostly transient and disappear after laser removal. Photoinduced phase transitions toward crystalline metastable states with a change of topological order are rare and difficult to predict and realize experimentally. Here, by using constrained density functional perturbation theory and accounting for light-induced quantum anharmonicity, we show that ultrafast lasers can permanently transform the topologically trivial orthorhombic structure of SnSe into the topological crystalline insulating rocksalt phase via a first-order nonthermal phase transition. We describe the reaction path and evaluate the critical fluence and possible decay channels after photoexcitation. Our simulations of the photoexcited structural and vibrational properties are in excellent agreement with recent pump–probe data in the intermediate fluence regime below the transition with an error on the curvature of the quantum free energy of the photoexcited state that is smaller than 2%.

Redefining the decisional components of motor responses: Evidence from lexical and object decision tasks

Models of decision making focusing on two-alternative choices have classically described motor-response execution as a nondecisional stage that serially follows the termination of decision processes. Recent evidence, however, points toward a more continuous transition between decision and motor processes. We investigated this transition in two lexical decisions and one object decision task. By recording the electromyographic (EMG) signal associated with the muscle responsible for the manual responses (i.e., button press), we partitioned single-trial reaction times into premotor (the time elapsing from stimulus onset until the onset of the EMG burst) and motor times (the time elapsing from the onset of the EMG burst and the button press), with the latter measuring response execution. Responses were slower for pseudowords and pseudo-objects compared to words and real objects. Importantly, these effects were reliable even at the level of motor time measures. Differently, despite the reliable effect at the level of reaction times and premotor times, there was no difference in motor times between high- and low-frequency words. Although these results, in line with recent evidence, challenge a purely noncognitive characterization of motor-response execution, they further suggest that motor times may selectively capture specific decisional components, which we identify with late-occurring verification and/or control mechanisms.

Nascent entrepreneurs during start-up competitions: Between beauty contests and co-created problematization
Bastian B.
Zucchella A.
Bastian, B.
Zucchella, A.
Problem-oriented research is increasingly gaining currency in entrepreneurship research. In this article, we respond to the need for more action-based perspectives in entrepreneurship. By employing an inductive research design based on qualitative interviews and participant observations, we discuss empirical evidence about two alternative problem formulation processes in the context of start-up competitions. We find that entrepreneurs may perceive start-up competitions as ‘beauty contests’, with the consequence of overpromised expectations, misaligned goals, and underutilized use of resources. The beauty contest represents a traditional interpretation of start-up competitions because it concentrates mainly on impressions and misses addressing real problems that entrepreneurs face. An alternative model for a new breed of start-up competitions is represented by co-created problematization, which challenges conventional thinking with a joint role for entrepreneurs and academics. We reflect on the mediating role of co-creation in a problem formulation process from joint problem definition toward joint problem solution, describe possible frictions, and highlight the need to re-design start-up competitions and shift towards a co-created setting where a confrontation between practitioners and academics is stimulated.

Obtained from online newspapers, it contains 1.5M+ article/summary pairs in five different languages - namely, French, German, Spanish, Russian, Turkish. Together with English news articles from the popular CNN/Daily mail dataset, the collected data form a large scale multilingual dataset which can enable new research directions for the text summarization community. We report cross-lingual comparative analyses based on state-of-the-art systems. These highlight existing biases which motivate the use of a multi-lingual dataset.

A deep multiple instance learning approach based on coarse labels for high-resolution land-cover mapping
Perantoni, Gianmarco
Bruzzone, Lorenzo
Bruzzone, Lorenzo
Bovolo, Francesca
Perantoni, Gianmarco
Bruzzone, Lorenzo
The quantity and the quality of the training labels are central problems in high-resolution land-cover mapping
with machine-learning-based solutions. In this context, weak labels can be gathered in large quantities by
leveraging on existing low-resolution or obsolete products. In this paper, we address the problem of training
land-cover classifiers using high-resolution imagery (e.g., Sentinel-2) and weak low-resolution reference data (e.g.,
MODIS-derived land-cover maps). Inspired by recent works in Deep Multiple Instance Learning (DMIL), we
propose a method that trains pixel-level multi-class classifiers and predicts low-resolution labels (i.e., patch-level
classification), where the actual high-resolution labels are learned implicitly without direct supervision. This
is achieved with flexible pooling layers that are able to link the semantics of the pixels in the high-resolution
imagery to the low-resolution reference labels. Then, the Multiple Instance Learning (MIL) problem is re-framed
in a multi-class and in a multi-label setting. In the former, the low-resolution annotation represents the majority
of the pixels in the patch. In the latter, the annotation only provides us information on the presence of one of
the land-cover classes in the patch and thus multiple labels can be considered valid for a patch at a time, whereas
the low-resolution labels provide us only one label. Therefore, the classifier is trained with a Positive-Unlabeled
Learning (PUL) strategy. Experimental results on the 2020 IEEE GRSS Data Fusion Contest dataset show the
effectiveness of the proposed framework compared to standard training strategies.

On Neighbors, Groups and Application Invariants in Mobile Wireless Sensor Networks
Guna, Stefan-Valentin
Picco, Gian Pietro
Guna, Stefan-Valentin
Settore INF/01 - Informatica
The miniaturization and energy-efficient operation of wireless sensor networks (WSNs) provides unprecedented opportunities for monitoring mobile entities. The motivation for this thesis is drawn from real-world applications including monitoring wildlife, assisted living, and logistics. Nevertheless, mobility unveils a series of problems that do not arise in fixed scenarios. Through applications, we distill three of those, as follows. Neighbor discovery, or knowing the identity of surrounding nodes, is the precondition for any communication between nodes. As compared to other existing solutions, we provide a framework that approaches the problem from the perspectives of latency (the time required to detect an amount of contacts), lifetime (the time nodes are expected to last) and probability (the fraction of contacts guaranteed to be detected within a given latency). By formalizing neighbor discovery as an optimization problem, we obtain a significant improvement w.r.t. the state-of-art. We offer a solver providing the optimal configuration and an implementation for popular WSN devices. Group membership, or knowing the identity of the transitively connected nodes, can be either the direct answer to a requirement (e.g., caring for people that are not self-sufficient), or a building-block for higher-level abstractions. Earlier works on the same problem target either less constrained devices such as PDAs or laptops or, when targeting WSN devices, provide only post-deployment information on the group. Instead, we provide three protocols that cover the solution space. All our protocols empower each node with a run-time global view of the group composition. Finally, we focus on the behavior of the processes monitored by WSNs. We present a system that validates whether global invariants describing the safe behavior of a monitored system are satisfied. Although similar problems have been tackled before, the invariants we target are more complex and our system evaluates them in the network, at run-time. We focus on invariants that are expressed as first-order logic formulas over the state of multiple nodes. The requirement for monitoring invariants arises in both fixed and mobile environments; we design and implement an efficient solution for each. Noteworthy is that the solution targeting mobility bestows each node with an eventually consistent view on the satisfaction of the monitored invariants; in this context, the group membership algorithms play the role of global failure detectors.

Anisotropic dimensional change on sintering has been studied in depth in previous work, as affected by powder mix, geometry, sintering conditions etc. Previous results also revealed anisotropic dimensional changes in the compaction plane, to be necessarily considered when designing precise and accurate parts. Anisotropy in the compaction plane is expected to be markedly affected by inhomogeneities in green density distribution, in turn related to compaction strategy. Aiming at investigating in depth the influence of the compaction strategy, compaction speed, hold down force, and hold down time were selected as parameters. Full factorial testing was performed, three levels for each parameter, and three different materials were considered. Dimensional changes were measured, and the effect of the selected parameters was analyzed, also referring to the different sintering mechanisms occurring in the different materials. As a result, relationships describing the effect of the compaction parameters on the dimensional changes are proposed.

Functional formalism for algebraic classical and quantum field theories
Moro, Andrea
Brunetti, Romeo
Moro, Andrea
In the first part of this thesis we study the generalization of the recent algebraic approach to classical field theory by proposing a more general setting based on the manifold of smooth sections of a non-trivial fiber bundle. Central is the notion of observables/functionals over such sections, i.e. appropriate smooth functions on them. The kinematic will be further specified by means of Peierls brackets, which in turn are defined via the causal propagators of linearized field equations. In the second part we implement deformation quantization of the algebras obtained previously in the simpler setting of scalar field theory. Wick powers and time ordered products for quantum field theories in curved spacetimes are defined by giving a set of axioms which, when implemented, defines uniquely, up to some classifiable ambiguities, the aforementioned quantities. Those ambiguities are known to be tightly restrained by locality, covariance and other regularity conditions. One of the additional constraints used was to require continuous and analytic dependence on the metric and coupling parameters. It was recently shown that this rather strong requirement could be weakened, in the case of Wick powers, to the so-called parametrized microlocal spectrum condition. We therefore show the existence of Wick powers satisfying the above condition and extend this axiom to time ordered products, while reestablishing the usual uniqueness and existence results in light of the new constraint.

Thinking Security:
A Reflectivist Approach to France's Security Policy-Making in sub-Saharan Africa
Erforth, Benedikt
Della Sala, Vincenzo
Erforth, Benedikt
Settore SPS/04 - Scienza Politica
RRecent years have witnessed increased French military activism in Africa. Despite efforts to normalise its post-colonial relationship and considerable downsizing of its permanent military presence, France remains a sought-after actor in solving African security problems. Notwithstanding French decision-makers repeated promises that the gendarme of Africa belongs to the past, French troops have participated in nine military operations since the turn of the millennium. Against all expectations, the Hollande administration has stood out for being particularly interventionist, concerting a military intervention in Mali and deploying a peacekeeping force to the Central African Republic within two years of assuming office. The ambiguity between an interventionist policy and a disengaged discourse suggests that French military interventionism in sub-Saharan Africa no longer follows the same automaticity as in the past. The two interventions in Mali and the CAR testify to the intense ideational struggles between different belief systems that had shaped French actorsâ minds and thus influenced decision-making processes and policy outcomes. Economic interests and neo-colonial continuity have been traditionally identified as the root causes of French interventionism in francophone Africa. For the past two decades the literature on French-African relations has been dominated by the so-called continuity vs. change debate, which scrutinises the presence of colonial / neo-colonial practices in the post-1990 French foreign policy. While ideational approaches to Franceâ s African policy are not rare, few studies have engaged with the decision-making processes that produce French military interventions. Most studies focus on policy outcomes, which are rooted in static conceptualisations of ideas that are aggregated at the level of the state. Starting from these observations, the present study argues that the mere analysis of policy outcomes tells us little about the actual motivations that drive French foreign and security policy in Africa. Instead of analysing French interventionism by relying on a predefined set of explanatory variables that are juxtaposed with a series of observable outcomes in order to falsify predefined hypotheses, this thesis explains French interventionism by drawing on actorsâ subjective perceptions and motivations. The study uses the actorsâ own utterances to explain why French decision-makers are ready to accept the considerable risks and costs involved in guaranteeing or re-establishing the security of African countries. Adopting an actor-centred constructivist ontology, this study not only identifies ideas as core explanatory variables but also traces their emergence and subsequent development throughout decision-making processes. This approach goes beyond the dichotomous view that reduces French motivations to material interests or post-colonial ambitions. Relying on discursive material such as official statements, verbatim reports of press conferences and parliamentary hearings, policy reports, and thirty-two high-level interviews with French decision-makers, the present study narrates military intervention in Mali and the CAR from the perspective of French foreign policy elites under the Hollande Presidency. This recent and largely unexplored empirical material provides new insights into Franceâ s foreign and defence policy. The study also demonstrates why and how the â Africa factorâ still matters in Franceâ s foreign policy considerations. The importance of Africa in Franceâ s security policy has less to do with neo-colonial ambitions per se, than with the understanding French policy-makers have of themselves and their country. More generally, the findings show how comprehensive explanations of foreign policy can be produced by considering actorsâ subjective perceptions. In so doing, the study not only explains Franceâ s current policies in sub-Saharan Africa, but also offers insights into foreign policy decision-making processes in general, and thereby provides further evidence about how ideational factors influence the making of world politics. Keywords: France, Africa, Mali, CAR, foreign policy analysis, international security, decision-making, political psychology, constructivism

In a Nearly Zero Energy Building (NZEB) design framework, passive design techniques are fundamental to guarantee indoor comfort of occupants, also ensuring a low energy consumption. Among these techniques, internal area heat capacity (IAHC) design still needs further field studies in full-scale constructions: a simple change in this parameter, without varying the mass of the load-bearing walls structure, can positively affect the whole building thermal behavior. Furthermore, combining this design solution with the automated control of windows shadings can help avoiding high temperature peaks due to uncontrolled solar gains. The present paper focuses on the monitoring of the indoor thermal conditions in four real scale residential buildings in the Alpine region of Northern Italy. The buildings present four different combinations of lightweight and massive load-bearing and interior cladding structure. After a first 8-days period of comparison of the pure thermal performance of the four structures, the impact of automated shadings, controlled by a basic and simplified algorithm, on lightweight cladding buildings was studied by means of a second monitoring period of eleven days. Besides confirming the remarkable impact of massive cladding on buildings’ thermal performance, the results showed that the basic automated regulation of shadings allowed to mitigate the lower thermal performances of lightweight cladding, also potentially improving the indoor thermal comfort conditions.

Multi-robot patrolling for dynamic coverage in flat environments is proposed, through a systematic simulative analysis between the Greedy Bayesian Strategy and the Expected Reactive algorithm based on the expected idleness. The two approaches are compared against unreliable communications, communication and sensing range, and number of conflicts. In addition, we introduce a new weighting-term for the regions close to a quantity of interest detected by robots, decreasing the passing-time for those regions. Combining the proposed control strategy and a traditional distributed and recursive Weighted Least Square estimation algorithm, the swarm is capable to compute the quantity of interest position with a desired target uncertainty. Extensive simulations and comparisons are reported.

Nonlinear Isocapacitary Concepts of Mass in 3-Manifolds with Nonnegative Scalar Curvature

We deal with suitable nonlinear versions of Jauregui’s isocapacitary mass in
3-manifolds with nonnegative scalar curvature and compact outermost minimal boundary.
These masses, which depend on a parameter 1 < p ≤ 2, interpolate between Jauregui’s mass p = 2 and Huisken’s isoperimetric mass, as p → 1
+. We derive positive mass theorems for these masses under mild conditions at infinity, and we show that these masses do coincide
with the ADM mass when the latter is defined. We finally work out a nonlinear potential theoretic proof of the Penrose inequality in the optimal asymptotic regime.

Essays on Farm Household Decision-Making: Evidence from Vietnam
Vu, Minh Hien
Gilbert, Christopher

Settore SECS-P/06 - Economia Applicata
This thesis contains three studies which provide theoretical analysis and empirical evidence on the decision-making of farm households under shocks and imperfect markets in Vietnam. The first study attempts to investigate the effects of the 2007-08 global food crisis on the investment, saving and consumption decisions of household producers by using the panel data of the Vietnam Household Living Standard Survey (VHLSS), covering 2006 and 2008. The results show that the high food prices had a positive effect on only fixed asset investments in the period of the crisis. When the price shocks are incorporated in the financial conditions, the findings reveal that the effects of household incomes, loans obtained and land sizes matter. The second study uses the Vietnam Access to Resources Household Survey (VARHS) of 2010 to assess the determinants of chemical fertiliser adoption for rice cultivation, and effects on productivity and household welfare. The analysis implements both nonparametric (propensity score matching) and parametric (instrumental variables) approaches. The findings show determinants affecting decision of adoption differ from those affecting decision of adoption intensity. The results show unsurprisingly positive impact on outcomes, but focus on advantage of using parametric approach to estimate these impacts. The third study employs a sub-sample from the 2008 VHLSS that is restricted to rural areas and to children from 10 to 14 years old to explore the relationship between farmland and the employment of children on their family’s farm. The hypothesis is tested in three models (the Tobit, Heckit and double-hurdle models), in which the dependent variables are examined for two stages of decision-making, including the probability of participation and the extent of participation. Empirical evidence supports the hypothesis that child labour increases in land-rich households and decreases in land-poor households.

Innovation in Agricultural Risk Management. A Behavioral Economic Approach
Rippo, Ruggiero
Cerroni, Simone
Rippo, Ruggiero
Settore AGR/01 - Economia ed Estimo Rurale
This thesis investigates the behavioral mechanisms and drivers that hinder or facilitate farmers’ adoption of innovative risk management strategies. A relatively small but growing research stream shows that farmers’ decisions to manage risk in their farms are often affected by behavioral factors like habits, experience, subjective expectations of future events, risk and uncertainty attitudes. The thesis focuses on the adoption of the latest risk management tool proposed under the EU Common Agricultural Policy (CAP): the Income Stabilization Tool (IST). The IST is a mutual fund which aims at stabilizing farm income over time. In particular this thesis is centered on the recent introduction, in 2019, of an IST scheme for the apple sector in the Autonomous Province of Trento (PAT), in Italy. To date, this is the only region in the whole EU that has developed this new risk management tool since its introduction in the 2013’s CAP reform.
The thesis explores farmers’ decision to adopt this new tool performing two distinct but interrelated empirical analyses. The first study (study 1) explores behavioral mechanisms and drivers that can explain farmers’ decisions to participate to the new IST scheme using a three years (2019- 2021) panel dataset of 3,268 apple producers from the PAT. This dataset contains information on farmers’ risk management decisions as well as farm and farmers’ characteristics. The behavioral model estimated in this study builds on a specific behavioral framework, the Unified Theory of Acceptance and Use of Technology (UTAUT) proposed by Venkatesh et al in 2003. The model is estimated using a logit model via the Mundlak–Chamberlain procedure. Results suggest that a higher crop production specialization and previous experience with similar tools increase participation in the IST. Interestingly, the adoption of the IST is mediated by farmers’ engagement with on-farm protection strategies (i.e., hail-nets and anti-frost systems), leading to a discussion of the presence of adverse and advantageous selection effects. The second empirical application (study 2) explores the internal and external validity of risk and uncertainty preferences elicited via a super-contextualized field experiment. External validity is explored by testing whether risk and uncertainty preferences are able to explain farmers’ decisions regarding the adoption of the IST and other risk management tool. This information is provided by the secondary data used in the first empirical application. The experiment was conducted in 2021 with a sample of 152 apple producers. The experimental results show that farmers are more averse to uncertainty than to risk. A higher degree of contextualization does not undermine the internal validity of elicited behavioral factors, while it can improve their external validity. These results provide support for using contextualized experiments that simulate real-world decision environment. Overall, these results indicate that behavioral drivers such as habit, experience, risk and uncertainty preferences play a role in explain farmers’ decision to adopt innovative risk management solutions. Institutions, organizations and private insurance companies that develop new risk management tools should consider these drivers when designing new tools, if they want to increase farmers’ adoption and improve farmers’ welfare.

ITALIAN ACADEMICS’ PUBLIC ENGAGEMENT: AN OPPORTUNITY TO STRENGTHEN THE RELATIONSHIP BETWEEN UNIVERSITIES AND THEIR TERRITORIES. The term Public Engagement refers to a variety of activities aimed at engaging universities within the public sphere and, correspondingly, at involving the public in the teaching, research and service activities of universities. These activities - which are largely carried out by faculty either on a mere individual basis or as an institutional duty - provide an opportunity to strengthen the relationships between universities and their territories. Relying on the results of a survey on more than 5,000 academics working at Italian public universities, the article aims at showing how frequent academics' Public engagement is, who are the academics mostly engaged in these activities, and whether there are territorial differences in this kind of engagement. The article also provides an assessment of the social and economic impact of Public engagement activities, especially at the local and regional levels. Distinguishing between two dimensions of academics' Public engagement, namely .Local Community Engagement. and .General Political Engagement., the article shows that Italian academics' participation in the former is considerable while their participation in the latter is limited. These findings suggest that academics' Public engagement indeed provides an opportunity to link universities to their territories. Local community engagement varies according to some individual characteristics such as academics' discipline and their involvement on other .Third mission. activities, but not to others. In particular, faculty working in Southern Italy and the Islands, the less developed regions of the country, and those working in North-West Italy, the most developed part of the country, are equally involved in Local community engagement. Finally, according to academics' perceptions their Local community engagement has a more social than economic impact.

Characterization of Small Molecules Inhibiting the RNA Binding Protein HuR
Lal, Preet
Provenzani, Alessandro
Lal, Preet
Settore BIO/11 - Biologia Molecolare
HuR, the ubiquitously expressed member of the ELAV (embryonic lethal abnormal vision) family of RNA binding proteins, selectively binds to AREs (AU-rich elements) and mainly stabilizes ARE-containing mRNAs, e.g. TNFα, VEGF, c-FOS, favoring specific protein translation. TNFα mRNA is one of the most important target mRNA of HuR since the protein encoded by this gene mediates the inflammatory response and its overexpression is correlated with autoimmune diseases and cancer-related inflammation. Specific drugs are already available that can inhibit TNFα protein but cause important side-effects, as insurgence of tumoral pathologies, due to high immunodepression. Therefore, inhibition of TNFα mRNA translation by specific inhibitors targeting HuR, only in those cells undergoing pathological anomalies, is an alternative, intriguing novel therapeutic approach that deserves investigation. By REMSA and AlphaScreen assays we identified a family of low molecular weight inhibitors, called Tanshinones, among which DHTS-I (Dihydrotanshinone – I) was the most potent. Tanshinones are well known in the traditional Chinese Medicine Practice, and these anti-inflammatory agents possess the ability to prevent HuR-RNA complex formation in vitro. We further identified structural determinants of HuR and DHTS interaction using RRM1&RRM2 tandem domains. EMSA and AlphaScreen experiments, with truncated ΔRRM1 and mutants revealed that DHTS is a competitive binder of HuR with respect of target RNA. To ameliorate the solubility of DHTS, we synthesized a number of DHTS analogs, of which the most potent and soluble compound was named MFM49. We evaluated the anti-inflammatory potential of DHTS and DHTS analogs and the HuR-dependent mechanism of action, revealing that, at least in part, DHTS and DHTS analogs rely on HuR to exert their mechanism of action. Influence on NF-kB activation by DHTS and MFM49 upon LPS co-stimulation was not seen in immunofluorescence studies. So here, we disclose a previously unrecognized molecular mechanism of action exerted by DHTS, and anti-inflammatory potential of DHTS analogs opening new perspectives to therapeutically target the HuR mediated, post-transcriptional control in inflammation and cancer like anomalies.
