Fair Production and Allocation of an Excludable Nonrival Good

We study fairness in economies with one private good and one partially excludable nonrival good. A social ordering function determines for each profile of preferences an ordering of all conceivable allocations. We propose the following Free Lunch Aversion condition: if the private good contributions of two agents consuming the same quantity of the nonrival good have opposite signs, reducing that gap improves social welfare. This condition, combined with the more standard requirements of Unanimous Indifference and Responsiveness, delivers a form of welfare egalitarianism in which an agent's welfare at an allocation is measured by the quantity of the nonrival good that, consumed at no cost, would leave her indifferent to the bundle she is assigned.

Sharing the Cost of a Public Good without Subsidies

We study the construction of a social ordering function for the case of a public good financed by contributions from the population, and we extend the analysis of Maniquet and Sprumont (2004) to the case when contributions cannot be negative, i.e. agents cannot receive subsidies from others.

Relative Egalitarianism and Related Criteria

We reconsider the problem of aggregating individual preference orderings into a single social ordering when alternatives are lotteries and individual preferences are of the von Neumann-Morgenstern type. Relative egalitarianism ranks alternatives by applying the leximin ordering to the distributions of (0-1) normalized utilities they generate. We propose an axiomatic characterization of this aggregation rule and discuss related criteria.

Strategy-proof preference aggregation

An aggregation rule maps each profile of individual strict preference orderings over a set of alternatives into a social ordering over that set. We call such a rule strategyproof if misreporting one’s preference never produces a social ordering that is strictly between the original ordering and one’s own preference. After describing a few examples of manipulable rules, we study in some detail three classes of strategy-proof rules: (i)rules based on a monotonic alteration of the majority relation generated by the preference profile; (ii)rules improving upon a fixed status-quo; and (iii) rules generalizing the Condorcet-Kemeny aggregation method.

Práticas organizativas em escolas de samba: o setor de harmonia da Vai-Vai

As escolas de samba são organizações peculiares do Brasil e têm sido foco de análise da sociologia e da antropologia há décadas. Nos Estudos Organizacionais muito pouco foi explorado a respeito dessa forma de organização e suas práticas organizativas para a produção de um desfile carnavalesco. Estudar esse universo pode contribuir para compreendermos como uma organização popular desempenha práticas de organizar capazes de produzir o macro-ator escola de samba, responsável pelos desfiles que fizeram o carnaval brasileiro ser conhecido mundialmente. É nesse sentido que o objetivo desta tese é investigar e analisar as práticas organizativas da produção do desfile de uma escola de samba do grupo especial da cidade de São Paulo. Para tanto, tomei como referência o trabalho do setor de harmonia da agremiação, cujas atividades são centrais no processo de produção do desfile. A tese está alinhada com o movimento na área de Estudos Organizacionais em direção ao estudo das práticas, o qual parte da idéia de que os fenômenos que se desdobram na realidade são conseqüência de práticas locais e acontecem por meio delas e de arranjos materiais nos quais humanos e não-humanos estão engajados na sua constituição. Tendo em vista essas noções, utilizei a Teoria Ator-Rede, uma abordagem que fornece um repertório analítico capaz de ajudar a entender o processo da ordenação social como efeito de uma rede heterogênea de elementos, na qual diversos e contraditórios interesses são negociados e uma estabilidade temporária alcançada. O trabalho de campo, desenvolvido com base em alguns princípios etnográficos, foi realizado junto ao setor de harmonia da escola de samba Vai-Vai. Durante a pesquisa eu fiz observações, entrevistas e reuni uma série de documentos referentes ao processo de produção do desfile. Tomando como ponto de partida minha relação com os sujeitos da pesquisa, analisei as transformações na minha identidade ao longo da pesquisa e as implicações disso para o trabalho. Ao seguir os atores e suas práticas organizativas pude identificar os principais espaços e arranjos materiais nos quais essas práticas se desdobram e o conjunto de controvérsias que se estabelece em torno dos diversos interesses envolvidos. Em cada um dos espaços (re)tracei os elementos da rede-de-atores e mostrei como as práticas organizativas coexistem com processos de desorganização. Essa se apresentou uma característica marcante das práticas de produção do desfile. Discuto na tese que as práticas organizativas ocorrem por meio de processos de translação entre os harmonias e vários outros atores humanos e não-humanos. Mostro ainda como as fronteiras de uma escola de samba são fluidas e as dicotomias comumente usadas para analisá-las ocultam uma forma de organização heterogênea. Concluo que as práticas organizativas são compostas por uma série de atores (humanos e não-humanos) que transladam seus interesses e contínuos esforços são realizados para estabilizar a rede-de-atores em constante estado de (re)constituição. Na conclusão destaco também que os elementos não-humanos são agentes ativos nas práticas organizativas e da pesquisa de campo e deveríamos atentar um pouco mais para sua presença.

A retórica em Aristóteles: da orientação das paixões ao aprimoramento da eupraxia

This research brings into focus the relationship between the work Rhetoric, from Aristotle, and the conceptions of ethics and practical wisdom of the philosopher from Stageira. Accordingly, it attempts to show that Aristotle's Rhetoric was produced to guide the construction and orientation of oratory passions of the Greek man, setting it as a reference for practices aimed at social ordering of the polis. In other words, the Aristotelian Rhetoric, designed by the author as the study of what is persuasive in every speech, is not composed with the meaning of persuasion at any cost, in another sense it is conceived by Aristotle as a useful knowledge for the improvement eupraxic (the good act in accordance with the fair and true). This research finds that such work has been prepared by Stagirite a time of strong social transformations and upheavals in ancient Greece: The skepticism expanded, with each person wanting to live their own businesses, and especially in Athens, a city that served as intellectual and political reference, there was a lack of collective spirit. In this tumultuous social environment, Aristotle, with a culture of Greeks eager Trusted reviews and socially shareable in the field of verisimilitude, sought with his Rhetoric, contributing to the development of ethics and political science; referrals for legal and organization of inter-social relations in varied environments, including seeking to provide knowledge about human passions and emotional status of active citizens in deliberative meetings

On the perspectives of the implementation of 'corporate social responsibility'

In the face of changes in corporate regulation scholarship, the percepts of corporate governance and legal policies have minimized the controversies over the potentials and limitations of corporate accountability mechanisms. In the contemporary scholarly works on the implementation of corporate social responsibility (CSR), there are evidences that support CSR principles to be implemented through legal regulation. Scholars and current practices, however, emphasize that this implementation should not be based on any single strategy. From this perspective, this article argues that the regulatory strategies for this implementation should be based on a fusion of legal sanction, market incentives and the demand of private ordering.

Legal Regulation of Corporate Social Responsibility : A Meta-Regulation Approach of Law for Raising CSR in a Weak Economy

"Even though Corporate Social Responsibility (CSR) has become a widely accepted concept promoted by different stakeholders, business corporations' internal strategies, known as corporate self-regulation in most of the weak economies, respond poorly to this responsibility. Major laws relating to corporate regulation and responsibilities of these economies do not possess adequate ongoing influence to insist on corporate self-regulation to create a socially responsible corporate culture. This book describes how the laws relating to CSR could contribute to the inclusion of CSR principles at the core of the corporate self-regulation of these economies in general, without being intrusive in normal business practice. It formulates a meta-regulation approach to law, particularly by converging patterns of private ordering and state control in contemporary corporate law from the perspective of a weak economy. It proposes that this approach is suitable for alleviating regulators' limited access to information and expertise, inherent limitations of prescriptive rules, ensuring corporate commitment, and enhance the self-regulatory capacity of companies. This book describes various meta-regulation strategies for laws to link social values to economic incentives and disincentives, and to indirectly influence companies to incorporate CSR principles at the core of their self-regulation strategies. It investigates this phenomenon using Bangladesh as a case study."--publisher website

Exploring the Roles of Technology and Social Play in Art Museums

This co-written chapter was included in an edited book featuring invited authors from different countries and different areas of museum research and practice. The chapter uses a theory of play by Johan Huizinga (1938) to frame case studies of play-based interactive experiences in museums in various countries. The aim was to use theory to ground museum practice, in order to evaluate existing practical implementations as well as to inform the design of new ones. The book was nominated as one of the 10 best museum education books of 2011 by Museum Education Monitor, and the chapter led to a subsequent technology residency the author undertook in the Spike Island gallery, Bristol in 2012, funded by the National Endowment for Science, Technology and the Arts, Arts and Humanities Research Council and Arts Council England. It also informed his subsequent postgraduate teaching, an example of which is a recent MA project, which deconstructs play from a computational perspective. Collaborations have continued with the co-author, which have resulted in a number of invited lectures. In this chapter the authors explore play as a structure for supporting visitor learning, drawing from international research in museums and interaction design. Four aspects of play first proposed by Huizinga are explored – the free-choice aspect of play, play as distinct from real life, play as an ordering structure, and the role of play in bridging communities. The chapter argues that play provides museums with ready-made structures and concepts, which can help planning for visitor learning. The research was equally divided between the co-authors, who developed the conceptual and theoretical aspects of the article by drawing on their own research alongside key examples of museum design and digital media.

The Possibility of Ordering Infinite Utility Streams

This paper revisits Diamond’s classical impossibility result regarding the ordering of infinite utility streams. We show that if no representability condition is imposed, there do exist strongly Paretian and finitely anonymous orderings of intertemporal utility streams with attractive additional properties. We extend a possibility theorem due to Svensson to a characterization theorem and we provide characterizations of all strongly Paretian and finitely anonymous rankings satisfying the strict transfer principle. In addition, infinite horizon extensions of leximin and of utilitarianism are characterized by adding an equity preference axiom and finite translation-scale measurability, respectively, to strong Pareto and finite anonymity.

An axiomatic characterization of the MVSHN group fitness ordering

In order to analyze a unicellular-multicellular evolutionary transition, a multicellular organism is identified with the vector of viabilities and fecundities of its constituent cells. The Michod–Viossat–Solari–Hurand–Nedelcu index of group fitness for a multicellular organism is a function of these cell viabilities and fecundities. The MVSHN index has been used to analyze the germ-soma specialization and the fitness decoupling between the cell and organism levels that takes place during the transition to multicellularity. In this article, social choice theory is used to provide an axiomatic characterization of the group fitness ordering of vectors of cell viabilities and fecundities underlying the MVSHN index.

O Serviço social nas organizações não-governamentais: tendências e particularidades

The present study is about the professional exercise of the Social Worker in ONGs associated with the ABONG in Natal city, state of Rio Grande do Norte, referring to the work conditions, claims and professional responses in front of the capital restructuration circumstances. The group of socio-historical transformations, as a result of the after-1970 dynamic capitalism, conducts a process of new configurations in the relationship between State and society that directly affect the social question nowadays, destroying social rights historically conquered for the workers. In this context, the ONGs assume a strategical social function of the social question, contributing with the change of responsibilities with the social from the State to the third sector. This social movement causes changes to the Social Work since this is one of the professions that act on the immediate expressions of the social question. After a qualitative research based on a theoricalmethodological critical and dialectical perspective, it was possible to discover some contradictions, details and tendencies of the professional exercise of the Social Worker in ONGs. Summarizing, the results of the research show that: a) it was detected a tendency of precarization, instability, insecurity, no-articulation, no-profissionalization of the professionals in the work conditions; b) demands are associated with a moment of the capital re-ordering, where new professional exigencies and responsibilities are related with capital necessities in the period of structural crisis; c) limits and contradictions are present in a professional daily work mainly in function of the characteristics of gestation and functioning of the ONGs; d) the professionals that were interviewed show significant difficulties in a articulation between the professional daily work in organizations and the totality of the social processes, limiting the capability of doing critics to the requisitions imposed by the capital
