Full textAbstract:
We propose a new functional form characterization of binary nonmanipulable social choice functions on a universal domain and an arbitrary, possibly infinite, set of agents. In order to achieve this, we considered the more general case of two-valued social choice functions and describe the structure of the family consisting of groups of agents having no power to determine the values of a nonmanipulable social choice function. With the help of such a structure, we introduce a class of functions that we call powerless revealing social choice functions and show that the binary nonmanipulable social choice functions are the powerless revealing ones.

Full textAbstract:
A promising direction in computational social choice is to address research problems using computer-aided proving techniques. In particular with SAT solvers, this approach has been shown to be viable not only for proving classic impossibility theorems such as Arrow's Theorem but also for finding new impossibilities in the context of preference extensions. In this paper, we demonstrate that these computer-aided techniques can also be applied to improve our understanding of strategyproof irresolute social choice functions. These functions, however, requires a more evolved encoding as otherwise the search space rapidly becomes much too large. Our contribution is two-fold: We present an efficient encoding for translating such problems to SAT and leverage this encoding to prove new results about strategyproofness with respect to Kelly's and Fishburn's preference extensions. For example, we show that no Pareto-optimal majoritarian social choice function satisfies Fishburn-strategyproofness. Furthermore, we explain how human-readable proofs of such results can be extracted from minimal unsatisfiable cores of the corresponding SAT formulas.

Full textAbstract:
We determine the quality of randomized social choice algorithms in a setting in which the agents have metric preferences: every agent has a cost for each alternative, and these costs form a metric. We assume that these costs are unknown to the algorithms (and possibly even to the agents themselves), which means we cannot simply select the optimal alternative, i.e. the alternative that minimizes the total agent cost (or median agent cost). However, we do assume that the agents know their ordinal preferences that are induced by the metric space. We examine randomized social choice functions that require only this ordinal information and select an alternative that is good in expectation with respect to the costs from the metric. To quantify how good a randomized social choice function is, we bound the distortion, which is the worst-case ratio between the expected cost of the alternative selected and the cost of the optimal alternative. We provide new distortion bounds for a variety of randomized algorithms, for both general metrics and for important special cases. Our results show a sizable improvement in distortion over deterministic algorithms.

Full textAbstract:
In multi-criteria decision making, any Group Decision Support System (GDSS) requires a social judgment model for calculation of weights on decision alternatives, and tabulation of individual votes toward a consensus. One could assess a Social Welfare Function - such as Keeneys - to aggregate individual cardinal preferences or utilities into a group preference. Alternatively, one could use Social Choice Functions - such as Condorcet, Borda, Copeland, and Eigenvector - to aggregate individual ordinal preferences or rankings into a group ranking. This study empirically investigates the consensus between individual preferences and the group preference derived from various aggregation methods.

Full textAbstract:
Thesis advisor: Uzi SegalThis dissertation consists of three chapters analyzing preferences for randomization in social choice problems. The first two chapters are related and in the fields of distributive justice and social choice. They concern allocation of an indivisible good in social choice problems where efficiency is at odds with equality. The last chapter addresses a social choice problem from an individual's perspective using decision theoretical analysis. In this dissertation I demonstrate why randomization may be an attractive policy in social choice problems and demonstrate how individuals may have preferences over the precise method of randomization. The first chapter is titled "Live and Let Die." This paper discusses how to allocate an indivisible good by social lottery when agents have asymmetric claims. Intuition suggests that there may exist agents who should receive zero probability in the optimal social lottery. In such a case, I say that these agents have weak claims to the good. This paper uses a running example of allocating an indivisible medical treatment to individuals with different survival rates and reactions to the treatment in order to provide conditions for consistency of weak claims. As such, I develop two related assumptions on a social planner's preferences over lotteries. The first -- survival rate scaling -- states that if an individual has a weak claim, then his claim is also weak when survival rates increase proportionally. The second -- independence of weak claims -- states that if an individual has a weak claim, then his removal does not affect others' probabilities of receiving the treatment. These assumptions imply that a compatible social welfare function must exhibit constant elasticity of substitution, which results in potentially-degenerate weighted lotteries. The second chapter is titled "Why is Six Afraid of Seven? Bringing the "Numbers" to Economics." This chapter discusses the numbers problem: the question of if the numbers of people involved should be used to determine whether to help certain people or to help certain other people. I discuss the main solutions that have been proposed: flipping a coin, saving the greater number, and proportionally weighted lotteries. Using the economic tools of social choice, I then show how the model of the previous chapter, "Live and Let Die," can be extended to address numbers problems and compare the implications of prominent social welfare functions for numbers problems. I argue that potentially-degenerate weighted lotteries can assuage the main concerns discussed in the literature and I show that both the Nash product social welfare function as well as constant elasticity of substitution (CES) social welfare functions are compatible with this solution. Finally, I discuss a related problem known as "probability cases," in which individuals differ in survival chances rather than numbers of individuals at risk. When the model is extended to allow for both asymmetries in survival chances and numbers of individuals in groups, CES results in potentially-degenerate weighted lotteries whereas Nash product does not. The third chapter is titled "All Probabilities are Equal, but Some Probabilities are More Equal than Others," which is joint work with Professor Uzi Segal of the Economics Department at Boston College and Professor Shlomo Naeh of the Departments of Talmud and Jewish Thought at The Hebrew University of Jerusalem. In this chapter we compare preferences for different procedures of selecting people randomly. A common procedure for selecting people is to have them draw balls from an urn in turn. Modern and ancient stories (for example, by Graham Greene and the Talmud) suggest that such a lottery may not be viewed by the individuals as "fair.'' In this paper, we compare this procedure with several alternatives. These procedures give all individuals equal chance of being selected, but have different structures. We analyze these procedures as multi-stage lotteries. In line with previous literature, our analysis is based on the observation that multi-stage lotteries are not considered indifferent to their probabilistic one-stage representations. As such, we use a non-expected utility model to understand the preferences of risk-averse individuals over these procedures and show that they may be not indifferent between them

Examensarbetet handar om språkval Engelska. Mitt intresse väcktes när jag erfor detta kontroversiella ämne som lärarstuderande. Meningen med ämnet är att det är en hjälp för elever som inte klarar av att studera ytterligare ett språk och för elever som behöver extra stöd i engelska. Ämnet har dock misskötts då många elever väljer ämnet utav lathet eller utav taktiska skäl. Iden med att endast låta de elever som som verkligen behöver extra stöd i engelska har förlorats. Jag har utfört intervjuermed sex olika lärare på fyra olika skolor angående hur språkval engelska är organiserat. Alla skolor har olika organisationer. Jag använde mig av formella intervjuer. Resultatet av dessa var att organisationen fungerar olika bra på de olika skolorna. Orsakerna till detta är många. På de skolor där det inte fungerar lika bra anges orsaker så som att ämnet har låg status, stora heterogena grupper och lärare och elever som är omotiverade.This dissertation deals with what in Swedish schools is called ”Språkval Engelska”. It will be refered to as Language Choice English in the ongoing text. My interest was aroused after having experienced this controversial subject as a student teacher. I found that different schools work with the subject in different ways. There is no clear syllabus for the subject since the grading is a part of the ordinary English grade. Language Choice English is an option for those who do not want to choose French, German or Spanish as Language Choice. The idea is that the subject is meant for those who cannot cope with yet another language and who need extra support in English. This study shows that not only the so-called weak pupils choose to study Language Choice English. There has been a mismanagement of the subject since so many pupils who are good at English choose it out of convenience and for tactical reasons. The idea of only letting those pupils, who actually need more support choose it, has been lost. Four different secondary schools have been investigated concerning how Language Choice English is organized. I learned that all of these schools have different organizations. The method I used was formal interviews with six different teachers at four different schools. The results of the interviews show that at some schools the subject works well. At other schools it does not. The reasons for this seem to be many. Reasons such as low status of the subject, large and heterogeneous groups and pupils and teachers who are unmotivated can be mentioned.

Dada a grande quantidade de dados gerados atualmente, apenas uma pequena porção dos mesmos pode ser rotulada manualmente por especialistas humanos. Isso é um desafio comum para aplicações de aprendizagem de máquina. Aprendizado semi-supervisionado aborda este problema através da manipulação dos dados não rotulados juntamente aos dados rotulados. Entretanto, se apenas uma quantidade limitada de exemplos rotulados está disponível, o desempenho da tarefa de aprendizagem de máquina (e.g., classificação) pode ser não satisfatória. Diversas soluções abordam este problema através do uso de uma ensemble de classificadores, visto que essa abordagem aumenta a diversidade dos classificadores. Algoritmos como o co-training e o tri-training utilizam múltiplas partições de dados ou múltiplos algoritmos de aprendizado para melhorar a qualidade da classificação de instâncias não rotuladas através de concordância por maioria simples. Além disso, existem abordagens que estendem esta ideia e adotam processos de votação menos triviais para definir os rótulos, como eleição por maioria ponderada, por exemplo. Contudo, estas soluções requerem que os rótulos possuam um certo nível de confiança para serem utilizados no treinamento. Consequentemente, nem toda a informação disponível é utilizada. Por exemplo: informações associadas a níveis de confiança baixos são totalmente ignoradas. Este trabalho propõe uma abordagem chamada social-training, que utiliza toda a informação disponível na tarefa de aprendizado semi-supervisionado. Para isto, múltiplos classificadores heterogêneos são treinados com os dados rotulados e geram diversas classificações para as mesmas instâncias não rotuladas. O social-training, então, agrega estes resultados em um único rótulo por meio de funções de escolha social que trabalham com agregação de rankings sobre as instâncias. Especificamente, a solução trabalha com casos de classificação binária. Os resultados mostram que trabalhar com o ranking completo, ou seja, rotular todas as instâncias não rotuladas, é capaz de reduzir o erro de classificação para alguns conjuntos de dados da base da UCI utilizados.Given the huge quantity of data currently being generated, just a small portion of it can be manually labeled by human experts. This is a challenge for machine learning applications. Semi-supervised learning addresses this problem by handling unlabeled data alongside labeled ones. However, if only a limited quantity of labeled examples is available, the performance of the machine learning task (e.g., classification) can be very unsatisfactory. Many solutions address this issue by using a classifier ensemble because this increases diversity. Algorithms such as co-training and tri-training use multiple views or multiple learning algorithms in order to improve the classification of unlabeled instances through simple majority agreement. Also, there are approaches that extend this idea and adopt less trivial voting processes to define the labels, like weighted majority voting. Nevertheless, these solutions require some confidence level on the label in order to use it for training. Hence, not all information is used, i.e., information associated with low confidence level is disregarded completely. An approach called social-training is proposed, which uses all information available in the semi-supervised learning task. For this, multiple heterogeneous classifiers are trained with the labeled data and generate diverse classifications for the same unlabeled instances. Social-training then aggregates these results into a single label by means of social choice functions that work with rank aggregation over the instances. The solution addresses binary classification cases. The results show that working with the full ranking, i.e., labeling all unlabeled instances, is able to reduce the classification error for some UCI data sets used.

As informações acerca da performance e impacto socioambientais do fornecedor e do produto são necessárias para o exercício do consumo de forma sustentável. O conhecimento dos impactos socioambientais advindos da produção, uso e pós-consumo é requisito para a livre escolha dos consumidores por produtos que apresentem impactos socioambientais positivos em qualquer dessas fases de seu ciclo de vida. Um dos instrumentos para o alcance do desenvolvimento sustentável é possibilitar o consumo de produtos que utilizem menos recursos finitos da natureza e que tragam melhorias sociais como suas consequências. No Brasil, o fundamento para a inclusão dos dados socioambientais do produto nas informações veiculadas ao consumidor está presente no ordenamento jurídico, na garantia de acesso à informação e no direito à preservação do meio ambiente, ambos inseridos no rol dos direitos constitucionais fundamentais, ao lado do princípio da dignidade da pessoa humana, bem como em preceitos do Código de Defesa do Consumidor e da legislação ambiental. A função social da empresa decorrente do princípio constitucional da função social da propriedade também justifica o dever de veiculação dos dados referentes ao impacto socioambiental de seus produtos e acerca do comportamento socioambiental da empresa. A veiculação desses dados beneficia a concorrência, acarretando o aperfeiçoamento dos próprios meios de produção para atrair os consumidores que optam por produtos sustentáveis. Os deveres de clareza e veracidade, decorrentes do princípio da boa-fé objetiva previstos no CC e CDC, necessitam ser observados na veiculação dessas informações para evitar a maquiagem socioambiental, que é a divulgação da falsa imagem de preocupação socioambiental ao produto. A essencialidade ou utilidade das informações é o parâmetro para sua veiculação sob o risco de ocorrer seu excesso, que impede a correta compreensão de todos os dados apresentados. Até os riscos de impactos socioambientais ainda não comprovados cabem ser informados em atenção ao princípio da precaução. O repasse dessas informações pode e deve ocorrer por todos os meios de comunicação utilizados para a divulgação dos produtos, ressaltando-se o papel da rotulagem.The information concerning the social-environmental impact of the product and the of the producers performance are necessary for the exercise of the sustainable consumption. The knowledge of the social-environmental impacts of the life cycle impact of the product is a requisite for the free choice of the consumers for products that present positive social-environmental impacts in any of these phases of its cycle of life. One of the instruments for the reach of the sustainable development is to make possible the consumption of products that use less finite resources of the nature and that they bring social improvements as its consequences. In Brazil, is possible to conclude that the legal system establishes the inclusion of the social-environmental data of the product in the information propagated to the consumer. Brazilian Constitution imposes the guarantee of access to the information, the consumer protection and the right of the preservation of the environment, as well as the dignity of the person human being. The social function of the companies, based in the constitutional principle of the social function of the property also justifies the duty of propagation of the referring data to the social-environmental impact of its products and concerning the social-environmental behavior of the company. In the legislative basis, there are strong rules concerning information in the Code of Defense of the Consumer and the environmental legislation. The propagation of these data benefits to the competition, creating incentives to the companies improving the means of production to attract the consumers that opt to sustainable products. The duties of clarity and veracity, attached with the good-faith principle established by Civil Code and Consumer Defense Code, need to be observed in the propagation of this information to prevent the greenwashing, that it is the propagation of the false image of social-environmental concern to the product. The essentiality or utility of the information is the parameter for its propagation under the risk to occur its excess, which hinders the correct understanding of all the presented data. Until the risks of social-environmental impacts not yet proven, they fit to be informed in attention to the Precautionary Principle. The view of this information can and must occur by all means of communication used for the spreading of the products, standing out itself the paper of the labeling.

Diese Dissertation untersucht verschiedene soziale sowie landschaftsästhetische Funktionen der Landwirtschaft in strukturell gegensätzlichen Agrarsystemen. In der Untersuchung wird hierfür stets ein von kleinen Familienbetrieben dominiertes System mit einem stärker großstrukturierten, gewerblichen System verglichen. Die Arbeitszufriedenheit der Landwirte sowie ihre soziale Vernetzung mit der lokalen Gemeinde wurden im Vergleich zwischen dem kleinbäuerlichen Schweizer und dem großbetrieblichen nordostdeutschen System analysiert. Mittels Choice Experimenten wurden in der Schweiz und in Süddeutschland (d.h. kleinbäuerliche Systeme) sowie in Ostdeutschland (d.h. großstruktiertes, gewerbliches System) zudem Bevölkerungspräferenzen für Agrarlandschaften und damit die ästhetische Funktion der Landwirtschaft untersucht. Unter Berücksichtigung der Betriebsstruktur (z.B. Betriebsgröße) sind Schweizer Bauern zufriedener mit ihrer Arbeit als nordostdeutsche. Das Betriebseinkommen ist für nordostdeutsche Bauern signifikant wichtiger für die Arbeitszufriedenheit als für die Schweizer Kollegen. Besonders für Schweizer Bauern spielt die Betriebsdiversifizierung eine positive Rolle für die Zufriedenheit, z.B. die Vielfalt der Produktionszweige oder nicht-landwirtschaftliche Betriebszweige wie Agrotourismus. Auch haben Schweizer Bauern und solche kleinerer Betriebe mehr Bezug zu ihrer lokalen Gemeinde durch lokal fokussierte soziale Netzwerke. Betriebsleiter größerer Betriebe sind hauptsächlich außerhalb der Gemeinden vernetzt und fühlen sich diesen weniger zugehörig. Zudem stärkt ein biographischer Bezug zum Hof die Verbindung mit der Gemeinde. Die Mehrheit der befragten Schweizer und Ostdeutschen ist zudem für qualitative Veränderungen der Agrarlandschaften (d.h. mehr Weiden zur Freilandhaltung, Streuobstwiesen und höhere Biodiversität). Waldrückgange sowie Schlaggrößenveränderungen landwirtschaftlicher oder forstlicher Flächen werden nahezu einheitlich abgelehnt.This dissertation investigates different social functions of agriculture as well as landscape aesthetics in farming systems of different agricultural structures. Throughout the whole project farming systems dominated by small family farms and large-scale farming systems dominated by commercial non-family farms (e.g. cooperatives) were compared. Farmers’ work satisfaction and their connection to the local community were examined in the small-scaled Swiss system and in the larger scaled Northeast (NE) German one. Public landscape preferences were derived using choice experiments in Switzerland and South Germany, representing small-scale systems, as well as in East Germany, representing a large-scaled one, to explore agriculture‘s aesthetic function. Swiss farmers are more satisfied with their agricultural work if for effects of farm structure (e.g. farm size) is controlled for. Farm income plays a significantly more important role for the work satisfaction of NE German farmers than for that of Swiss ones. Especially for Swiss farmers, farm diversification plays an important role, for example through a diversity of production lines or through non-agricultural activities like agrotourism. Further results show that Swiss farmers and farmers of smaller farms are more connected to their local communities through more locally focused social networks. Farmers of larger farms have their networks farther away from the farm and a weaker sense of belonging to their local community. A biographical bond to the farm also strenghtens the connection to the local community. Concerning public landscape preferences the majority of the Swiss and East German respondents generally prefers qualitative changes to landscapes (i.e. meadows for free range animal husbandry, meadow orchards and more biodiversity). Forest loss or changes in plot sizes of agricultural land and forests are nearly uniformly rejected in all regions.

Full textAbstract:
Physical activity is essential for children and adults to counteract the negative health outcomes related to a sedentary lifestyle. Despite widely publicized recommendation and information about physical activity the problem of excessive physically inactivity prevails in our society. The purpose of this study was to conduct a context functional analysis to identify outdoor activity contexts that engendered higher levels of MVPA and to adopt Dunlap, DePerczel, Clarke, Wilson, Wright, White, and Gomes’ (1994) methodology by utilizing an ABAB reversal design to determine if choice making influences levels of moderate-to-vigorous physical activity (MVPA) in six preschool-aged children. Results of the context functional analysis showed that fixed equipment and open space engendered highest levels of MVPA in most participants. Levels of MVPA in the reversal design indicated that choice did not significantly influence levels of MVPA and that healthy and unhealthy choices varied between and within participants. These results suggest that related to levels of MVPA the type of outdoor activity context chosen is more important than the individual who chooses it.

Epilepsy is a brain dysfunction characterized by the repeated tendency of the brain to cause epileptic crisis and by the neurobiological, cognitive, psychological and social consequences of this condition. In these terms, the aim of this work is to determine the visual sensory threshold of children and adolescents who have and who do not have epilepsy, analyzing possible alterations in the form related to this dysfunction. The sensory threshold is defined as the smallest intensity of incentive a human being is capable of detecting. The contrast sensitivity function (CSF) is the inverse of the threshold curve of contrast (1/CSF). This way, the CSF is a tool that allows us to label the answer of SV to visual patterns in low, medium and high levels of contrast and evaluate possible sensorial alterations associated with the visual processing. The main idea is that the elevation or reduction of the CSF can happen deem to sensorial, cognitive and behavioral alterations. Twenty volunteers participated on this study, from both genders, between 7 and 17 years of age, 10 of whom nonepileptic and 10 epileptic (tonic-clonic crisis). All of them presented either normal or corrected visual accuracy and were distributed in groups that were equivalent in age. The resolutions were taken from the psychophysical forced-choice method, using the static sine wave gratings with spatial frequencies of 0.25, 2.0 and 8.0 cpd (cycles per degree of visual angle). During each experimental session, there were stimulus pares presented randomly (test stimulus and neutral), and the task of the participants was to choose always the test stimulus with one of the frequencies above. The criterion used was the one of three consecutive correct answers to low the contrast in one unity and just one mistake to increase the contrast in the same unity (20%). After each session, a sheet of results with the experimental situation was released and the six values of contrast were calculated by the reversions. The values of contrast obtained to each frequency were grouped in spreadsheets separated by condition (with or without epilepsy) and the big average was used as an estimative of the sensory threshold or of the sensibility to the contrast due to each spatial frequency tested. The analysis of variance (ANOVA) to repeated measures showed significant differences between the groups [F(1,238) = 11.80); p<0.01]. The analysis obtained with the help of the test posthoc Tukey HSD revealed a relevant dissimilarity only in the 0.25cpg (p<0.01)]. In other words, the results indicated an expressive alteration in the visual perception children and adolescents with epilepsy have.
A epilepsia é um distúrbio cerebral caracterizado pela predisposição persistente do cérebro para gerar crises epilépticas e pelas conseqüências neurobiológicas, cognitivas, psicológicas e sociais desta condição. Algumas pesquisas demonstram que distúrbios visuais são bastante freqüentes em pessoas com epilepsia. Nestes termos, o objetivo deste trabalho foi determinar o limiar sensório visual de crianças e adolescentes com e sem epilepsia, verificando possíveis alterações na percepção visual da forma relacionadas a este transtorno. O limiar sensório é definido como a menor intensidade de um estímulo que um ser humano é capaz de detectar. A função de sensibilidade ao contraste (FSC) é o inverso da curva de limiar de contraste (1/FSC). Assim, a FSC é uma ferramenta que permite caracterizar a resposta do SV para padrões visuais em níveis baixos, médios e altos de contraste e avaliar possíveis alterações sensoriais relacionadas ao processamento visual. A idéia principal é que a elevação ou redução da FSC pode está relacionada a alterações sensoriais, cognitivas e comportamentais. Participaram deste estudo, 20 voluntários de ambos os sexos com idades entre 7 e 17 anos, sendo 10 sem epilepsia e 10 com epilepsia (crises tônicoclônicas). Todos apresentavam acuidade visual normal ou corrigida e foram distribuídos pelos grupos atendendo ao critério de equivalência de idade. As medidas foram realizadas com o método psicofísico da escolha forçada, utilizando grade senoidal vertical estática com freqüências espaciais de 0,25; 2,0 e 8,0 cpg (ciclos por grau de ângulo visual). Durante cada sessão experimental, foram apresentados aleatoriamente pares de estímulos (estímulo de teste e neutro), e a tarefa dos participantes foi escolher sempre o estímulo de teste com uma das freqüências acima. O critério adotado foi o de três acertos consecutivos para diminuir o contraste em uma unidade, e apenas um erro para aumentar o contraste na mesma unidade (20%). Após cada sessão, o programa produzia uma folha de resultados com a situação experimental e os seis valores de contraste conseguidos pelas reversões. Os valores de contraste obtidos para cada freqüência foram agrupados em planilhas por condição (com e sem epilepsia) e a grande média foi utilizada como estimativa do limiar sensório ou da sensibilidade ao contraste em função de cada freqüência espacial testada. A análise de variância (ANOVA) para medidas repetidas mostrou diferenças significantes entre os dois grupos [F(1, 238) =11,80); p < 0,01]. Já a análise com o teste post-hoc Tukey HSD revelou diferença significante apenas na faixa de freqüências de 0,25 cpg (p < 0,01). Em termos gerais, os resultados demonstraram alteração significante na percepção visual da forma de crianças e adolescentes com epilepsia.

Miller, Bryon G. "Behavioral assessment of physical activity preferences of young children." Scholarly Commons, 2014. https://scholarlycommons.pacific.edu/uop_etds/293.
Full textAbstract:
Low levels of physical activity are correlated with negative health outcomes such as heart disease, diabetes, and certain types of cancer. This is concerning given the current rise in obesity and physical inactivity, especially in young children. Developing assessments that can readily identify variables related to unhealthy patterns of activity might be useful in informing interventions that aim to increase physical activity. The current study extended previous research in the functional analysis of physical activity by Hustyi, Normand, and Larson (2012) by evaluating the utility of a choice assessment procedure to identify participant preference to several common outdoor activity contexts, typically available during school recess. Together, the two assessments strategies were able to identify both healthy and less healthy patterns of responding in four preschool-age children. The information obtained from these assessments could be used to inform behavioral interventions that aim to increase physical activity in young children.

Full textAbstract:
Humans are unique in their ability to flexibly and rapidly adapt their behaviour and select courses of action that lead to future reward. Several ‘component processes’ must be implemented by the human brain in order to facilitate this behaviour. This thesis examines two such components; (i) the neural substrates supporting action selection during value- guided choice using magnetoencephalography (MEG), and (ii) learning the value of environmental stimuli and other people’s actions using functional magnetic resonance imaging (fMRI). In both situations, it is helpful to formally model the underlying component process, as this generates predictions of trial-to-trial variability in the signal from a brain region involved in its implementation. In the case of value-guided action selection, a biophysically realistic implementation of a drift diffusion model is used. Using this model, it is predicted that there are specific times and frequency bands at which correlates of value are seen. Firstly, there are correlates of the overall value of the two presented options, and secondly the difference in value between the options. Both correlates should be observed in the local field potential, which is closely related to the signal measured using MEG. Importantly, the content of these predictions is quite distinct from the function of the model circuit, which is to transform inputs relating to the value of each option into a categorical decision. In the case of social learning, the same reinforcement learning model is used to track both the value of two stimuli that the subject can choose between, and the advice of a confederate who is playing alongside them. As the confederate advice is actually delivered by a computer, it is possible to keep prediction error and learning rate terms for stimuli and advice orthogonal to one another, and so look for neural correlates of both social and non-social learning in the same fMRI data. Correlates of intentional inference are found in a network of brain regions previously implicated in social cognition, notably the dorsomedial prefrontal cortex, the right temporoparietal junction, and the anterior cingulate gyrus.

Full textAbstract:
Recently, public policies of urban regeneration have intensified and multiplied. They are being promoted with the aim to start social and economic dynamics within the local context which is subject to intervention. From the empirical analysis, we realise that such activities are mainly implemented by three subjects or by mixed coalitions (public institutions, actors of the third sector and companies). Within them, each player is moved by a multiplicity of interests and goals that go beyond their own nature – public interest, market and mutualism – and tend to redefine themselves, thus becoming hybrid forms of production of value (social, economic, cultural). By studying a number Italian and Catalan cases, this essay deals with the theory that, under specific conditions and configurations, a collaborative direction – of organization, production and design – would give life to successful procedures, even without the identification of a one-best-way. The collaboration is not simply a choice of operation, but a real production method which mobilises social resources to create hybrid solutions – between state, market and society – to complex issues that could not be faced solely with the use of the rationale of action of one among the three actors. In this framework, the systems of relations and interactions between players and shared capital become an essential condition for the success of every initiative of urban redevelopment, or failure thereof. Such initiatives are brought to life by the strategic role of individuals who foster connections as well as the dissemination of non-redundant information between social networks, and collective and individual actors which would otherwise be separated and barely able to communicate and collaborate with each other. In addition to the functions carried out by knowledge brokers, that have been extensively described in organisational studies and economic sociology, the aforementioned figures act as real social enzymes, that is to say, they handle the available information and function as catalysts of social processes of production of knowledge. Moreover, they increase the reaction speed, working on mechanisms which control the spontaneity.

The research aims to analyse the concept of the 'holiday home' in Italy, a phenomenon that is not very well known and not given sufficient visibility in the tourism sector. The objective is to grasp the role and the degree of response that the holiday homes can offer in order to consolidate a genuinely social and sustainable tourism, which is the specific feature of the Associazione di Promozione Sociale Santa Lucia. The holiday homes represent an efficacious response to the emerging motivations for travel and a new sensitivity towards social and sustainable tourism. The growing opportunities for this sector call for reflection on the mission and future positioning of the holiday homes within the tourist reception panorama, with the deriving choices relating to: the offer, consisting of values more than of services; the functions fulfilled, intimately bound up with the demands of the individual and the territory; the quality of the service, which is not generic but linked to the functions and can be measured in line with objective and subjective parameters. Strategic awareness, managerial capacity and elevated professionalism at all levels are the factors of legitimisation and success of this original reception formula.

Full textAbstract:
This chapter provides an introduction to the use of social welfare functions in welfare economics and social choice theory for the comparative evaluation of social alternatives. With a social welfare function, social preferences depend on individual well-beings. These well-beings are expressed in terms of either preferences or utilities. Three main approaches are considered: Bergson-Samuelson social welfare functions, Arrovian social welfare functions, and Sen’s social welfare functionals. How the measurability and comparability of utility can be modeled and how limitations on the types of utility comparisons that are possible restrict the kinds of social welfare functions that can be considered is also discussed. Extensive social choice theory is used to deal with heterogeneous opinions about how to make utility comparisons.

Full textAbstract:
When aggregating preferences of multiple agents, strategyproofness is a fundamental requirement. For randomized voting rules, so-called social decision schemes (SDSs), strategyproofness is usually formalized with the help of utility functions. A classic result shown by Gibbard in 1977 characterizes the set of SDSs that are strategyproof with respect to all utility functions and shows that these SDSs are either indecisive or unfair. For finding more insights into the trade-off between strategyproofness and decisiveness, we propose the notion of U-strategyproofness which requires that only voters with a utility function in the set U cannot manipulate. In particular, we show that if the utility functions in U value the best alternative much more than other alternatives, there are U-strategyproof SDSs that choose an alternative with probability 1 whenever all but k voters rank it first. We also prove for rank-based SDSs that this large gap in the utilities is required to be strategyproof and that the gap must increase in k. On the negative side, we show that U-strategyproofness is incompatible with Condorcet-consistency if U satisfies minimal symmetry conditions and there are at least four alternatives. For three alternatives, the Condorcet rule can be characterized based on U-strategyproofness for the set U containing all equi-distant utility functions.

Full textAbstract:
While discrete choice analysis is prevalent in capturing consumers’ preferences and describing their choice behaviors in product design, the traditional choice modeling approach assumes that each individual makes independent decisions, without considering the social impact. However, empirical studies show that choice is social — influenced by many factors beyond engineering performance of a product and consumer attributes. To alleviate this limitation, we propose a new choice modeling framework to capture the dynamic influence from social network on consumer adoption of new products. By introducing the social influence attributes into the choice utility function, the social network simulation is integrated with the traditional discrete choice analysis in a three-stage process. Our study shows the need for considering social impact in forecasting new product adoption. Using hybrid electric vehicle as an example, our work illustrates the procedure of social network construction, social influence evaluation, and choice model estimation based on data from National Household Travel Survey. Our study also demonstrates several interesting findings on the dynamic nature of new technology adoption and how social network may influence consumers’ “green attitude” in hybrid electric vehicle adoption.

Full textAbstract:
This paper investigates the use of Symbolic Dynamic Filtering (SDF) algorithms in detecting anomalous behavior trends in social networks. Data is generated from an agent-based discrete choice model, which relies on a Markov Decision Process framework for stochastic simulation of decision-making in a social setting, where choices and decisions by individuals are influenced by social interactions. We show that such collective imitative behavior leads to rapid unstable fluctuations in the society, the fluctuation statistics being a weak function of the number of extremist nodes present in the network as well as the prevailing political climate. In this paper, using a time-trace of global opinions in the said society, we investigate the effectiveness of SDF in estimating the number of extremist nodes in a network, and studying the role of unpopular government policies as an enabler of political instability. Spread of influence and ‘recruiting’ by extremist groups through social networks has become an important political issue in recent years. This study is a step in the direction of building tools to preempt and intervene such efforts.

Full textAbstract:
Alapvető célunk, hogy számos korábbi vizsgálat adatbázisát felhasználva megalkossunk egy kategóriarendszert, amelynek felhasználásával megismerhető a fiatalok – szűkebben véve a felsőoktatásban részt vevő hallgatók – értékválasztása, annak motivációi. Ehhez elengedhetetlen, hogy a korábbi elemzéseink során kialakított értékrendszerek érvényességét ellenőrizzük. Tervezett előadásunkban arra keressük a választ, hogy a „kapcsolatorientált” hallgatók valóban aktívabbak a közösségi média által kínált lehetőségek kihasználásában, infokommunikációs szokásaik összhangban vannak-e értékválasztásukkal? A kérdőívvel történt adatfelvételek során használt értéksor a World Value Survey (WVS) által használt értékeken, értéksoron alapszik (Inglehart, 2000 és Inglehart – Baker, 2000). A Regionális Egyetem Kutatócsoport 2005-ös és 2010-es kérdőíves lekérdezésen alapuló adatbázisát felhasználva korábban meghatároztuk a hallgatói „értékcsoportokat”, feltártuk a hallgatók értékstruktúráját. A 2016-os Magyar Ifjúságkutatás adataira támaszkodva (A Kutatópont Kft. engedélyével) lehetőségünk nyílik arra, hogy az eddigi eredményeinket, kategóriáinkat összevessük egy jóval nagyobb minta, azaz a Kárpát-medence fiataljainak értékstruktúrájával, az általunk felállított kategóriák érvényességét ellenőrizzük. Az eredményekből kiderül, hogy az értékválasztás során felmért attitűd jellegű választások, vagyis az értékek rangsora milyen mértékben jár együtt az infokommunikációs eszközök használatából következtethető közösségiorientált viselkedéssel. Másként fogalmazva a „kapcsolatorientált” hallgatók mennyivel aktívabbak „anyagias” társaiknál? Nagyobb ívű elméleti vonatkozású vállalásunk, hogy megalkossunk egy, az ifjúságra alkalmazható értékrendszer-kategóriát, amely az ifjúság megváltozott társadalmi körülményei között is alkalmazható. Gyakorlati szempontból az értékrendszerek megfelelő alátámasztottság mellett egyéb társadalmi cselekvések esetén is prediktív funkcióval bírhatnak, vagyis az értékválasztás alapján regisztrálható különbségek a társadalmi élet különböző színterein (oktatás, munka világa, közösségi kapcsolatok) eltérő viselkedéseket vetítenek előre. .----- Students' info communication habits along their value choice ----- Our basic aim is to establish a category system using the database of many previous research, and by using this category system to learn about the value choice, and the motivation behind that value choice of the youth – more narrowly the value choice of students in higher education. To do so, it is essential to check the validity of the value systems established during our previous analysis. In our planned presentation we are looking for the answer whether “relationship-oriented” students are really more active in taking the advantages of the opportunities offered by social media, and whether their infocommunication habits are in line with their value choices. The values used in the survey are based on the values, value- lines applied by the World Value Survey (WVS) (Inglehart 2000 and Inglehart -Baker, 2000). Using the database of the 2005 and 2010 survey of the Regional University’s research team, we determined the „value groups”, and we explored the value structure of the students. Relying on the data from 2016 Hungarian Youth Research (with the permission of Kutatópont Kft.) we have the opportunity to compare our current results and categories against a considerably greater sample, namely against the value structure of the youth of the Carpathian Basin, therefore we can check the validity of the categories we established. The results show the extent to which the attitude-type choices assessed during value-selection, namely the ranking of values, are associated with community-oriented behaviour, that can be concluded from the use of infocommunication tools. In other words, how much more active “relationship-oriented” students are than their “material-oriented” peers. Our broader theoretical commitment is to create one value system category valid for the young which can also be applied in the changed social circumstances of the youth. From a practical point of view, value systems, with adequate support, can have a predictive function in case of other social actions, namely the differences registered in value choice project different behaviours in other spheres of social life (education, world of work, community relations).

Obviously strategyproof (OSP) mechanisms maintain the incentive compatibility of agents that are not fully rational. They have been object of a number of studies since their recent definition. A research agenda, initiated in [Ferraioli and Ventre, 2017], is to find a small set (possibly, the smallest) of conditions allowing to implement an OSP mechanism. To this aim, we define a model of probabilistic verification wherein agents are caught misbehaving with a certain probability, and show how OSP mechanisms can implement every social choice function at the cost of either imposing very large fines or verifying a linear number of agents.

Full textAbstract:
Social, economic, and environmental benefits of sustainable buildings result in increasing demand and supply of green office space and governments adopt green buildings requirements as policy instruments. Effect of public (local, state) policies on construction and diffusion of sustainable buildings have been analyzed in few research (e.g. (Choi 2010a), (R. Simons, Choi, and Simons 2009)), demand for sustainable offices (e.g. (Zieba, Belniak, and Gluszak 2013), motivations for investing (Fuerst and McAllister 2009)(Popescu et al. 2012) were the subject of research but the impact of public policies and tools used by local governments, in the form of development plans and zoning maps, on the location decisions of investors realizing green buildings still requires more insight.
The objective of this paper is to verify whether local development plans (zoning maps) facilitate location of sustainable office buildings on sites that are best-choice using the criteria of green buildings’ certification and most beneficial from the point of view of sustainable urban development.
Authors assume that local governments would support choice of best sustainable location by investors, as it’s beneficial for local community, economy and environment. Also, we state that real estate developers’ choice of location is the function of firm’s own criteria, zoning map restrictions, availability of land for new developments.
This paper proposes a methodology to identify the best areas to locate sustainable offices in Cracow district Zabłocie, using spatial data analysis.
Zablocie was selected because the zoning map exists for the whole district and the area - postindustrial district, still provides many sites for new developments and it’s featured by high concentration of sustainable office buildings.
The evaluation criteria was based on BREEAM (BRE Environmental Assessment Method) green building certification categories. The data was collected and processed in ArcGIS. The locations, identified in spatial analysis process, were compared with locations available in Zablocie for commercial (office) developments as indicated by local development plan.

Full textAbstract:
In light of climate change and other existential threats, policy commentators sometimes suggest that society should be more concerned about catastrophes. This document reflects on what is, or should be, society’s attitude toward such low-probability, high-impact events. The question underlying this analysis is how society considers (1) a major accident that leads to a large number of deaths; (2) a large number of small accidents that each kill one person, where the two situations lead to the same total number of deaths. We first explain how catastrophic risk can be conceived of as a spread in the distribution of losses, or a “more risky” distribution of risks. We then review studies from decision sciences, psychology, and behavioral economics that elicit people’s attitudes toward various social risks. This literature review finds more evidence against than in favor of catastrophe aversion. We address a number of possible behavioral explanations for these observations, then turn to social choice theory to examine how various social welfare functions handle catastrophic risk. We explain why catastrophe aversion may be in conflict with equity concerns and other-regarding preferences. Finally, we discuss current approaches to evaluate and regulate catastrophic risk, with a discussion of how it could be integrated into a benefit-cost analysis framework.

Full textAbstract:
The article investigates functional techniques of extralinguistic expression in multimedia texts; the effectiveness of figurative expressions as a reaction to modern events in Ukraine and their influence on the formation of public opinion is shown. Publications of journalists, broadcasts of media resonators, experts, public figures, politicians, readers are analyzed. The language of the media plays a key role in shaping the worldview of the young political elite in the first place. The essence of each statement is a focused thought that reacts to events in the world or in one’s own country. The most popular platform for mass information and social interaction is, first of all, network journalism, which is characterized by mobility and unlimited time and space. Authors have complete freedom to express their views in direct language, including their own word formation. Phonetic, lexical, phraseological and stylistic means of speech create expression of the text. A figurative word, a good aphorism or proverb, a paraphrased expression, etc. enhance the effectiveness of a multimedia text. This is especially important for headlines that simultaneously inform and influence the views of millions of readers. Given the wide range of issues raised by the Internet as a medium, research in this area is interdisciplinary. The science of information, combining language and social communication, is at the forefront of global interactions. The Internet is an effective source of knowledge and a forum for free thought. Nonlinear texts (hypertexts) – «branching texts or texts that perform actions on request», multimedia texts change the principles of information collection, storage and dissemination, involving billions of readers in the discussion of global issues. Mastering the word is not an easy task if the author of the publication is not well-read, is not deep in the topic, does not know the psychology of the audience for which he writes. Therefore, the study of media broadcasting is an important component of the professional training of future journalists. The functions of the language of the media require the authors to make the right statements and convincing arguments in the text. Journalism education is not only knowledge of imperative and dispositive norms, but also apodictic ones. In practice, this means that there are rules in media creativity that are based on logical necessity. Apodicticity is the first sign of impressive language on the platform of print or electronic media. Social expression is a combination of creative abilities and linguistic competencies that a journalist realizes in his activity. Creative self-expression is realized in a set of many important factors in the media: the choice of topic, convincing arguments, logical presentation of ideas and deep philological education. Linguistic art, in contrast to painting, music, sculpture, accumulates all visual, auditory, tactile and empathic sensations in a universal sign – the word. The choice of the word for the reproduction of sensory and semantic meanings, its competent use in the appropriate context distinguishes the journalist-intellectual from other participants in forums, round tables, analytical or entertainment programs. Expressive speech in the media is a product of the intellect (ability to think) of all those who write on socio-political or economic topics. In the same plane with him – intelligence (awareness, prudence), the first sign of which (according to Ivan Ogienko) is a good knowledge of the language. Intellectual language is an important means of organizing a journalistic text. It, on the one hand, logically conveys the author’s thoughts, and on the other – encourages the reader to reflect and comprehend what is read. The richness of language is accumulated through continuous self-education and interesting communication. Studies of social expression as an important factor influencing the formation of public consciousness should open up new facets of rational and emotional media broadcasting; to trace physical and psychological reactions to communicative mimicry in the media. Speech mimicry as one of the methods of disguise is increasingly becoming a dangerous factor in manipulating the media. Mimicry is an unprincipled adaptation to the surrounding social conditions; one of the most famous examples of an animal characterized by mimicry (change of protective color and shape) is a chameleon. In a figurative sense, chameleons are called adaptive journalists. Observations show that mimicry in politics is to some extent a kind of game that, like every game, is always conditional and artificial.

Our analysis indicates that most chargers need to be deployed in the first 10 to 15 years of the transition to allow benefits to accrue for electric vehicle drivers, availability of home charging influences consumers’ choice and drivers’ electrified travel distance, charging stations should be prioritized for frequent long-distance drivers, and spatial effects are crucial in accurately capturing the demand for electric vehicles in Illinois. We also develop a multi-criteria suitability map to site charging stations for electric vehicles based on economic, societal, and environmental justice indicators. We identify census tracts that should be prioritized during Illinois’ statewide deployment of charging infrastructure along with interstates and major highways that traverse them. Major interstates and highways I-90, I-80, I-55, and I-57 are identified as having high siting suitability scores for charging stations. Last, a novel location model was developed for equitable electric vehicle charging infrastructure placement in the Illinois interstate and major highway network. Two objectives were set to reduce detours and improve the ability to complete long-distance trips for low-income electric vehicle travelers and multi-unit dwelling residents. Our analysis indicates that if the system’s efficiency is the only consideration, low-income/multi-unit housing resident travelers are most likely to fail to complete their trips, while an equitable charging siting could mitigate this issue.
