The structure of fuzzy preferences: Social choice implications

It has been shown that, with an alternative factorization of fuzzy weak preferences into symmetric and antisymmetric components, one can prove a fuzzy analogue of Arrow's Impossibility Theorem even when the transitivity requirements on individual and social preferences are very weak. It is demonstrated here that the use of this specification of strict preference, however, requires preferences to also be strongly connected. In the absence of strong connectedness, another factorization of fuzzy weak preferences is indicated, for which nondictatorial fuzzy aggregation rules satisfying the weak transitivity requirement can still be found. On the other hand, if strong connectedness is assumed, the fuzzy version of Arrow's Theorem still holds for a variety of weak preference factorizations, even if the transitivity condition is weakened to its absolute minimum. Since Arrow's Impossibility Theorem appeared nearly half a century ago, researchers have been attempting to avoid Arrow's negative result by relaxing various of his original assumptions. One approach has been to allow preferences – those of individuals and society or just those of society alone – to be “fuzzy.” In particular, Dutta [4] has shown that, to a limited extent, one can avoid the impossibility result (or, more precisely, the dictatorship result) by using fuzzy preferences, employing a particularly weak version of transitivity among the many plausible (but still distinct) definitions of transitivity that are available for fuzzy preferences. Another aspect of exact preferences for which the extension to the more general realm of fuzzy preferences is ambiguous is the factorization of a weak preference relation into a symmetric component (indifference) and an antisymmetric component (strict preference). There are several ways to do this for fuzzy weak preferences, all of them equivalent to the traditional factorization in the special case when preferences are exact, but quite different from each other when preferences are fuzzy (see, for example, [3]). A recent paper in this journal [1], by A. Banerjee, argues that the choice of definitions for indifference and strict preference, given a fuzzy weak preference, can also have “Arrovian” implications. In particular, [1] claims that Dutta's version of strict preference presents certain intuitive difficulties and recommends a different version, with its own axiomatic derivation, for which the dictatorship results reappear even with Dutta's weak version of transitivity. However, the conditions used to derive [1]'s version of strict preference imply a restriction on how fuzzy the original weak preference can be, namely, that the fuzzy weak preference relation must be strongly connected. Without this restriction, I will show that the rest of [1]'s conditions imply yet a third version of strict preference, for which Dutta's possibility result under weak transitivity still holds. On the other hand, if one accepts the strong connectedness required in order for it to be valid, I show that [1]'s dictatorship theorem can in fact be strengthened to cover any version of transitivity for fuzzy preferences, no matter how weak, and further, that this dictatorship result holds for any “regular” formulation of strict preference, including the one originally used by Dutta.

Extending an order to the power set: The Leximax Criterion

This work analyzes the issue of ranking the levels of well-being enjoyed by an agent when dealing with her opportunity set in a freedom of choice context. We try to propose a natural extension of a preference relation over a (possibly) infinite set X to its power set, compatible with the finite Leximax criterion.

A systematic approach to the construction of non-empty choice sets

Suppose a strict preference relation fails to possess maximal elements, so that a choice is not clearly defined. I propose to delete particular instances of strict preferences until the resulting relation satisfies one of a number of known regularity properties (transitivity, acyclicity, or negative transitivity), and to unify the choices generated by different orders of deletion. Removal of strict preferences until the subrelation is transitive yields a new solution with close connections to the “uncovered set” from the political science literature and the literature on tournaments. Weakening transitivity to acyclicity yields a new solution nested between the strong and weak top cycle sets. When the original preference relation admits no indifferences, this solution coincides with the familiar top cycle set. The set of alternatives generated by the restriction of negative transitivity is equivalent to the weak top cycle set.     

Strategy-proof voting schemes with continuous preferences

We prove that all nondictatorial voting schemes whose range has more than two alternatives will be manipulable, when their domain is restricted to the set of all continuous preferences over alternatives. Our result neither implies nor is implied by the original Gibbard-Satterthwaite theorem, except if the number of alternatives is finite, when they coincide. A new, direct line of reasoning is used in the proof. It is presented in an introductory section, which may be useful in classroom situations.The work of S.

Inequality in voting power

This paper deals with the assessment of inequality in the distribution of voting power. Voting power is evaluated through a general concept of power measurement based on both the voting rule and the probability distribution over vote configurations. This general concept includes as particular cases the most usual power indices and other extensions of this traditional concept. Thus no particular power index is privileged in our approach. An inequality index over the class of all power profiles with a given number of voters generated by this general measure is then singled out by requiring reasonable properties. In order to compare profiles with different numbers of voters, two alternative principles are considered, which extend the said index consistently in two ways.Previous versions of this work were circulated under different titles.

Assessing success and decisiveness in voting situations

In this paper we propose a simple model for measuring success or decisiveness in voting situations. For an assessment of these features two inputs are claimed to be necessary: the voting rule and the voters behavior. The voting rule specifies when a proposal is to be accepted or rejected depending on the resulting vote configuration. Voting behavior is summarized by a distribution of probability over the vote configurations. This basic model provides a clear common conceptual basis for reinterpreting different power indices and some related game theoretic notions coherently from a unified point of view.The authors would like to thank to M. Braham, M. Machover, N. Megiddo and F. Steffen, for their comments, and to J. F. Mertens for pointing out a misstatement, in all cases referring to previous versions of this paper.

On continuity of incomplete preferences

A weak (strict) preference relation is continuous if it has a closed (open) graph; it is hemicontinuous if its upper and lower contour sets are closed (open). If preferences are complete these four conditions are equivalent. Without completeness continuity in each case is stronger than hemicontinuity. This paper provides general characterizations of continuity in terms of hemicontinuity for weak preferences that are modeled as (possibly incomplete) preorders and for strict preferences that are modeled as strict partial orders. Some behavioral implications associated with the two approaches are also discussed.     

Fuzzy preferences and Arrow-type problems in social choice

There are alternative ways of decomposing a given fuzzy weak preference relation into its antisymmetric and symmetric components. In this paper I have provided support to one among these alternative specifications. It is shown that on this specification the fuzzy analogue of the General Possibility Theorem is valid even when the transitivity restrictions on the individual and the social preference relations are relatively weak. In the special case where the individual preference relations are exact but the social preference relation is permitted to be fuzzy it is possible to distinguish between different degrees of power of the dictator. This power increases with the strength of the transitivity requirement.For comments on an earlier version of the paper I am indebted to an anonymous referee, an anonymous member of the Board of Editors and to participants in the 1991 Annual Conference of the Indian Econometric Society at North Bengal University, India.

The Paretian liberal with intuitionistic fuzzy preferences: A result

In the present paper we consider a situation in which the individual preferences and the social preference relation are intuitionistic fuzzy and study the compatibility between the Pareto principle and Sens minimal liberalism condition. A possible factorization of the intuitionistic fuzzy weak preference relation allows us to prove a possibility result for the case of max-min transitive social preference.I am extremely grateful to the Coordinating Editor and an anonymous referee of this journal for their detailed comments and suggestions.

Synergistic development and participatory action research in a Nahuat community

This is a report of twenty years of participatory action research conducted by a team of Mexican urban professionals with community members in a Nahuat indigenous region at Sierra Norte de Puebla (Mexico). The article first outlines three main issues of Latin American participatory action research projects. The context and the unfolding of the case are presented through five stages highlighting the role of the team, its relationship with the community along the years, and the development of some of their joint activities. In the final pages the authors evaluate the case in relation to the issues raised in the first section and discuss what is important about this process. María Eugenia Sánchez is a sociologist and President and Founder of Proyecto de Animación y Desarrollo, Asociación Civil (PRADE A.C.), the nongovernmental organization living and working since 1973 in San Miguel Tzinacapan (Mexico).

On randomized rationality

In contrast to the traditional notion of rationalizability of stochastic choice which requires the preference relations to be strict, we propose a notion of rationalizability without requiring the preference relations to be strict. Our definition is based on the simple hypothesis of a two-stage choice process: stage (i) a preference relation R is drawn according to a probability assignment; stage (ii) an alternative is picked from each feasible set according to a uniform lottery over the R-greatest set in it. We provide a necessary and sufficient condition for rationalizability of stochastic choice. Since our framework is general enough to subsume the traditional case, our result also provides an alternative characterization of the traditional notion of rationalizability. We also show the equivalence between the two notions of rationalizability in a specific case.     

Special majority rules necessary and sufficient condition for quasi-transitivity with quasi-transitive individual preferences

A condition on preferences called strict Latin Square partial agreement is introduced and is shown to be necessary and sufficient for quasi-transitivity of the social weak preference relation generated by any special majority rule, under the assumption that individual preferences themselves are quasi-transitive.     

Stability and voting by committees with exit

We study the problem of a society choosing a subset of new members from a finite set of candidates (as in Barberà et al. 1991). However, we explicitly consider the possibility that initial members of the society (founders) may want to leave it if they do not like the resulting new society. We show that, if founders have separable (or additive) preferences, the unique strategy-proof and stable social choice function satisfying founders sovereignty (on the set of candidates) is the one where candidates are chosen unanimously and no founder leaves the society.A previous version of this paper was entitled Voting by Committees with Exit.

Outside of the corporate mainstream and excluded from the work community: A study of diversity,job satisfaction and well-being

Research over the past two decades indicates that exclusion from organizational information networks and from important decision-making processes is one of the most significant problems facing today's diverse workforce. Employees' sense of exclusion may play a critical role in explaining the connection between lack of opportunities experienced by employees who are different from the corporate 'main stream' and their job satisfaction and well-being. This study examines the relationship between diversity characteristics, sense of inclusion, fairness, stress and social support and the outcome variables of job satisfaction and well-being. A sample of 3400 employees of diverse racial and ethnic backgrounds in the high-tech industry in Southern California completed a self-report questionnaire. Findings support the hypotheses that women and members of racial/ethnic minorities are more likely to feel excluded, and that exclusion is linked to job dissatisfaction and lower sense of well-being. The study further explores the potential role of exclusion as a mediator variable. These findings have implications for future research on workforce diversity and for organizational diagnosis and interventions aimed at creating a more inclusive workplace culture. Investigácion durante los últimos veinte anos indica que exclusión de cadena información del organización y exclusión de decisións importantes es uno de los problemas mas significante en el diverso mundo de trabajo. El sentido de exclusión de los empleados puede estar criticó en la explicación del connexión entre la falta de opportunidades para los empleados que son differentes del corriente principal y su satisfacion con trabajo y su bienestar. Este investigación explora el relation entre característicos diversos, sentido de inclusión, justicia, esfuerzo, y assistencia social, y los variables resultados de satisfacion con trabajo y bienestar. Este prueba de 3400 empleados de ethnicidades y razas differentes de un industria tecnológico en el sur de California han completo un cuestionario de su mismo. Conclusiones dar soporte al hipótesis que es mas probable que mujeres y los minorías de raza y ethnicidad sientan exculido, y que exclusión tiene connexión con desagrado con el trabajo y mas pequeno sentido de bienestar. Este prueba averiguares el posición de exclusión como un variable mediador. Estos conclusions tienen implicaciónes para los investigaciónes en el futuro con diversidad en trabajadores y para diagnosis con los organizaciónes y intervenciónes que quieren crear una cultura mas inclusivo en el organización.     

The Emancipatory Potential of Generic Globalization

The debate around globalization is entering a new and more mature phase reflected in the fact that it is now generally accepted that we live in an era of globalization. However, the concept is used in a bewildering variety of ways. Here I attempt to deconstruct it by distinguishing three modes of globalization in theory and practice, namely: generic, capitalist, and alternative globalizations. My argument is that globalization in a generic sense is too often confused with its dominant actually existing type, capitalist globalization. I define generic globalization in terms of (a) the electronic revolution; (b) postcolonialisms; (c) the subsequent creation of transnational social spaces; and (d) qualitatively new forms of cosmopolitanism. Capitalist globalization undermines the emancipatory potential of the four elements of generic globalization, resulting in what are termed here a new type of class polarization crisis and the crisis of ecological unsustainability. The article concludes with an attempt to sketch the main principles of a post-capitalist alternative form of democratic socialist globalization, based on networks of sustainable consumer-producer cooperatives operating at all appropriate social and geographical scales.

El debate sobre la globalización está entrando en una fase nueva y más madura, reflejada en el hecho de que ahora generalmente se acepta que vivimos en una era de globalización. Sin embargo, el concepto se usa en una variedad de formas confusas. Por este medio, trato de deconstruirlo, mediante la distinción de tres modos de globalización en teoría y en práctica, principalmente: globalizaciones genéricas, capitalistas y alternas. Mi argumento es que la globalización en un sentido genérico, se confunde frecuentemente con el tipo dominante de globalización que existe actualmente, la globalización capitalista. Yo defino la globalización genérica en términos de (a) revolución electrónica; (b) poscolonialismo; (c) la creación subsecuente de espacios sociales trasnacionales; y (d) nuevas formas cualitativas de cosmopolitismo. La globalización capitalista obstaculiza el potencial emancipador de los cuatro elementos de la globalización genérica, resultando en lo que hemos denominado aquí, un nuevo tipo de crisis de polarización de clases y la crisis de insostenibilidad ecológica. El artículo concluye con un intento de esbozar los principios fundamentales de una forma alterna poscapitalista de globalización democrática socialista, en base a redes de cooperativas de consumidor-productor sostenibles que operan a todos los niveles sociales y geográficos apropiados.

     

The Chairman’s Paradox Revisited

This paper re-examines the so-called ‘chairman’s paradox‘ that was first noticed by Farquharson in his path breaking tract on sophisticated voting, Theory of Voting (1969). The Chairman’s paradox is concerned with the case of a three member committee in which a particular player who has a regular and a tie-breaking vote – the ‘chairman’ – not only will do worse in specific instances under the plurality procedure for three alternatives than if he did not have such a vote, but will also do worse overall. That is, the chairman’s a priori probability of success (‘getting what one wants’) for all possible games with linear (strict) preference orders is lower than that of the two regular members. It is demonstrated that this result, which comes about if voters act strategically rather than sincerely, is not as robust as it has been thought to be. By merely replacing the standard assumption of linear preference orders with weak preference orders, which allow for indifference, we can escape from the paradox for the canonical case of three players and three alternatives. With weak preference orders, the a priori success of the chairman is now greater than that of the other two players. We also point to a new paradox of sophisticated voting.     

Land conflict in Nepal1

This paper examines the agrarian social relationships between peasant farmers and local feudal landlords. Using land conflict as a basis of analysis this paper explores the basic characteristics of a Nepalese power skewed rural society and its relation with land. A case study was conducted using key informants and semi-structured interviews, focus group discussion, questionnaire survey, and observation to examine the agrarian social relations. The paper highlights that reformative rules and regulations alone do not always govern the behaviour of powerful people in rural communities. Rather, context and time-specific, persistent local resistance movements force changes to their behaviour and associated power relations. The paper concludes that organized peasant movements could non-coercively change existing patron-client relations in agrarian society. Rural families and tenant farmers are able to establish their identity when they realize their strengths. Este papel examina las relaciones sociales agrarias entre campesinos y propietarios campesinos feudales locales. Usando el conflicto de la tierra como base del análisis, este papel explora las características básicas del poder asimétrico de la sociedad rural nepalés y su relación con la tierra. Se llevó a cabo un estudio de caso utilizando un informante clave y entrevistas semi-estructuradas, discusiones de un grupo muestra elegido y la inspección y observación de cuestionarios para examinar las relaciones agrarias sociales. El papel subraya que el comportamiento de la gente poderosa en la sociedad rural no siempre está gobernada sólo por las normas reformativas y por las reglas. Más bien, el contexto y los movimientos específicos y persistentes de resistencia local hacen cambiar su comportamiento y sus relaciones asociadas al poder. Se concluye que los movimientos campesinos organizados pueden cambiar sin coerción las relaciones existentes entre cliente y patrón en la sociedad agraria. Las familias rurales y los arrendatarios son capaces the establecer su identidad cuando se dan cuenta de sus fuerzas.     

Global Transformations but Local, ‘Bubble’ Lives: Taking a Reality Check on Some Globalization Concepts

Several concepts and arguments have become an indispensable part of the standard discourse shared by globalization theorists and they point convincingly to real and deepening processes in global life. The paper suggests, however, that it is misleading and ultimately unproductive to assume that the vast majority of the world's non-elite population possess an equal grasp of these concepts, and the processes which they are designed to illuminate, or that they are able or willing to take appropriate actions in response. With this in mind, and drawing on some recent theoretical critiques and empirical studies, the discussion interrogates ideas about interconnectivity, mobility, de-territorialization and globality. In doing so it argues that we need to pay much more attention to the everyday subjective lives of ordinary people since these continue to be locked into affiliations and obligations constructed, inevitably, as much around place as flows and which remain partly dependent on co-present, primordial socialities despite their exposure to multiple globalizing influences.

Varios conceptos y argumentos se han convertido en parte indispensable del discurso convencional compartido por teóricos de la globalización, los cuales señalan en una manera convincente los procesos reales y cada vez más profundos en la vida global. El documento sugiere, sin embargo, que no es productivo asumir que la gran mayoría de la población que no pertenece a la élite posea un entendimiento equivalente sobre estos conceptos, así como de los procesos que se diseñaron para ilustrarlos, o que sean capaces o deseen tomar las acciones apropiadas como respuesta. Con esto en mente, y basándose en algunas críticas teóricas recientes así como en estudios empíricos, la discusión interroga sobre interconectividad, movilidad, desterritorialización y globalidad. Al hacerlo, argumenta que debemos prestar mucha más atención a la vidas diarias subjetivas de la gente común, puesto que éstas continúan ligadas a afiliaciones y obligaciones elaboradas inevitablemente, tanto alrededor del lugar como de los flujos y que continúan permaneciendo parcialmente dependientes a socialismos copresentes y primordiales a pesar de su exposición a diversas influencias a favor de la globalización.     

Local and global practice: Relocating social work as a human rights profession in the new global order

Globalization, as currently understood, is confined to an economic world view, and does not include notions of global citizenship, social priorities and human rights. Yet social workers, because of the value base of the social work profession, must be concerned with these issues, and work towards a form of 'living in one world' that locates human values as paramount. One of the reactions to globalization has been an increase in localization, and social workers are now required to work at both global and local levels, and to relate the two. This is explored in relation to social work knowledge, values and skills, with particular reference to using a human rights framework for social work theory and practice. In a globalized world, all aspects of social work are affected by global issues, and all social problems have a global dimension. Hence international social work can no longer be a marginalized specialization within the social work profession, but must be part of the day-to-day practice of all social workers, if social work is to remain relevant to the pursuit of human rights and social justice. Die gegenärtigen Auffassungen von Globalisierung sind in einer ökonomischen Perspektive befangen und entbehren jeder Vorstellung von globaler Bürgerschaft, sozialen prioritäten und Menschenrechten. Aufgrund ihrer Wertebasis als soziale Profession kommt es f&ür Sozialarbeiterinnen und Sozialarbeiter darauf an, sich mit diesen Sachverhalten auseinanderzusetzen und auf eine Form des Zusammenslebens in einer Welt hinzuarbeiten, in der humane Werte an allererster Stelle stehen. Als eine Reaktionsweise auf die Globalisierung bildete sich eine verstärkte 'Lokalisierung' heraus. Dies bedeutet für die Sozialarbeiterinnen und Sozialarbeiter, daß sie nun auf beiden Ebenen arbeiten und diese zugleich miteinander verbinden müssen. Diese Aufgabe wird hier thematisiert im Hinblick auf das Wissen, auf die Werte und die Qualifikationen in der Sozialarbeit, und zwar unter besonderer Berürcksichtigung eines auf die Menschenrechte bezogenen Rahmenkonzepts für die Theorie und Praxis der Sozialen Arbeit. In einer globalisierten Welt sind alle Aspekte Sozialer Arbeit von globalen Entwicklungen betroffen, und umgekehrt haben alle sozialen Probleme eine globale Dimension. Wenn Soziale Arbeit Weiterhin eine relevante Rolle bei der Verwirklichung von sozialer Gerechtigkeit und den Menschenrechten zukommen soll, dann kann die internationale Dimension der Sozialarbeit nicht bloß eine marginale Specialisierung innerhalb der Profession bleiben, sondern muß zu einem integralen Bestandteil der tagtäglichen Praxis aller Sozialarbeiterinnen und Sozialarbeiter werden. La globalización tal como la entendemos actualmente, está confinada a un punto de vista economómico, y no incluye nociones de ciudadania global, prioridades sociales y derechos humanos. Pero los trabajadores sociales, debido a la base de valores existentes en la profesión de trabajo social, deben estar preocupados con estos temas, y trabajar hacia una forma de 'vivir en un mundo' que sitße los valores humanos en el ámbito de gran importancia que se merecen. Una de las reacciones a la globalización ha sido el aumento de la localización, y a los trabajadores sociales actualmente se les requiere la capacidad de trabajar en ambos niveles, global y local, y de relacionarlos. Exploramos estos aspectos en relación con el conocimiento en trabajo social, valores y destrezas, haciendo particular referencia a la capacidad de uso de un marco de derechos humanos como ase para la teoria y práctica del trabajo social. En un mundo globalizado todos los aspectos de trabajo social quedan afectados por temas globales, y todos los problemas sociales tienen una dimensión global. Por tanto, el trabajo social internacional no puede continuar siendo una especialidad marginal en la profesión, sino que debe formar parte de la práctica diaria de todos los trabajadores sociales si queremos que el trabajo social continße siendo relevante en la bßsqueda de los derechos humanos y justicia social.
