The Moulin–Shenker rule

The Moulin–Shenker rule is a non-linear solution concept for solving heterogeneous cost sharing problems. It is the unique continuous rule with the properties scale invariance, bounds on cost shares and self-consistency. I am indebted to several anonymous referees and especially to Hervé Moulin for many useful suggestions.     

A derivation of the money Rawlsian solution

We study the set of envy-free allocations for economies with indivisible objects and quasi-linear utility functions. We characterize the minimal amount of money necessary for its nonemptiness when negative distributions of money are not allowed. We also find that, when this is precisely the available amount of money, there is a unique way to combine objects and money such that these bundles may form an envy-free allocation. Based on this property, we describe a solution to the envy-free selection problem following a pseudo-egalitarian criterion. This solution coincides with the Money Rawlsian Solution proposed by Alkan et al. (1991).I am indebted to I. Gilboa for his valuable suggestions and his patience during the elaboration of the final version. I also wish to thank S. Barbera for his guidance in an earlier version and M. Boldrin, H. Moulin, Z. Neeman, W. Thomson and the referees for their comments. Financial support from FPU-MEC (Spain) is gratefully acknowledged.Northwestern University.     

Identical preferences lower bound solution and consistency in economies with indivisible goods

We consider the problem of allocating a finite set of indivisible goods and a single infinitely divisible good among a group of agents, and we study a solution, called the Identical Preferences Lower Bound solution, in the presence of consistency properties. This solution is not consistent. We prove that its maximal consistent subsolution is the No-envy solution. Our main result is that the minimal consistent extension of the intersection of the Identical Preferences Lower Bound solution with the Pareto solution is the Pareto solution. This result remains true in the restricted domain when all the indivisible goods are identical, but not when there is a unique indivisible good.This paper was developed during my stay at Rochester University in the summer of 1992. I would like to express my special thanks to Professor William Thomson for all his help and advice. Iam also grateful to my supervisor Luis Corchón, to Koichi Tadenuma and to the anonymous referees for their helpful comments. The remaining errors are my exclusive responsibility.

Managing manipulation: tools and challenges in creative collaborations with intellectually-disabled people

There has long been an ‘us’ and ‘them’ mentality when it comes to the production of disability narratives on screen, driven by an assumption that non-disabled people cannot accurately interpret the disabled experience. Given the appalling history of representations by non-disabled filmmakers, it is easy to understand why many academics and members of the disability community favour the complete control of disability content by disabled people. But this approach has failed the many compelling ‘disabled voices’ that go unheard because they do not reach audiences. The most practical solution is to forge new models of creative collaboration between disabled and non-disabled people, something I attempted to do with my PhD film, a comedy feature entitled Down Under Mystery Tour. I discovered that the most important tool in such collaborations is the utilisation and management of manipulation, one that prioritises skill and experience and best expresses the unique perspective of intellectually-disabled collaborators.     

Experiencing ‘Illegality’ as a Family? Immigration Enforcement,Social Policies,and Discourses Targeting Mexican Mixed‐Status Families

Mexican mixed‐status families have been front and center in embroiled national debates about the place of undocumented immigrants and their citizen family members in this country. These families face unique obstacles, including possible family fragmentation caused by deportation, challenges to birthright citizenship, and they are often targeted by anti‐immigrant elected officials and political pundits that perpetuate a racialized discourse that casts even citizen children in these families as an abomination of US citizenship. Therefore, “illegality” may be a familial experience that can be endured by citizens and non‐citizens alike. Despite their unique vulnerabilities, researchers know very little about how mixed‐status families experience belonging in the country while managing possible tensions and inequalities shaped by immigration status. In this article, I review the research on punitive immigration enforcement and the scholarship on social policies and discourse targeting mixed‐status families. I conclude by reviewing new directions in sociological research and suggest avenues for research that may examine mixed‐status families' subjectivities, belonging, and negotiations of family relationships.     

Why language is unique to human beings

There are some well-known theories about the origin of the language. The origin of the language is very mysterious. The theory of language origin can be divided into two hypotheses: continuity and discontinuity. The basic idea of the continuity hypothesis is that the language can't be suddenly formed, there must be a process from the human ancestors of the early evolution of the language system. The discontinuous hypothesis holds that language has some unique characteristics which come across in a certain period of time and relates to the human gene evolution and mutation. However, What I want to prove is neither of them, I prefer the religious views. In this thesis, I mainly talk about two aspects. Bible records the original history of human society, therefore, I'd like to find the answer of the origin of language from the Bible.     

North Central Sociological Association 2014 Teaching Address: The John F. Schnabel Lecture—Sociology’s Special Pedagogical Challenge

Instructors and students must overcome a course’s special pedagogical challenge in order for meaningful and important learning to occur. While some suggest that the special pedagogical problem varies by course, I contend that the special pedagogical problem is likely to be shared across a discipline’s curriculum, rather than being unique to each course. After reviewing a three-part typology of learning outcomes for sociology, I argue that the development of students’ sociological imaginations is sociology’s special pedagogical challenge; I then offer some general guidelines for teaching strategies to enhance the students’ success in developing a sociological imagination.     

A purely non-cooperative model of divided government

In this paper I describe an institutional structure in which there are two branches of the government: the executive one, elected by plurality rule, and the legislative one elected by proportional rule. The resulting policy outcome is described through a compromise between these two branches. Given the presidential result, legislative elections are characterized by essentially an unique Nash equilibrium such that any voter on the left of the corresponding policy outcome votes for the leftist party and any voter on the right votes for the rightist party. Moreover, this equilibrium can be obtained by a process of iterated elimination of dominated strategies. The whole game is then solved by backward induction and dominance arguments.I thank Francesco De Sinopoli, Jean-Francois Mertens, Howard Rosenthal and Jacques Thisse for very helpful discussions.     

Cripping sexualities: An analytic review of theoretical and empirical writing on the intersection of disabilities and sexualities

This paper provides a review of some of the literature addressing the juncture of disabilities and sexualities and invites sociologists to build on this work and take part in this important intersectional field. First, I discuss the central relevance of an intersectional lens for making sense of the unique experiences of queer people with disabilities who are located at the crossroads of various stratified systems. Then, I discuss some of the many unique challenges that queer disabled people face when exploring their sexuality, establishing relationships, and remaining sexual. The invisibility, marginalization, and discrimination of queer people with disabilities in both queer and disability communities are the focus on the third section. The fourth section speaks to current theoretical dialogues between disability studies and queer theory that have illuminated new pathways for theorizing the intersection of disabilities and sexualities, “cripping” sociological theories, and reimagining disability within sociology. As I demonstrate, this literature is growing; however, myriad exciting opportunities for empirical and theoretical sociological exploration remain and I will conclude with a discussion of possible directions for future research.     

Cultural Education: Redefining the Role of Museums in the 21st Century

In this paper, I argue that in the face of a crisis about the value of culture, cultural education has been represented by some of its advocates as a new way of legitimising the cultural sector. It enables museums, for example, to appear more inclusive and democratic, more relevant to young people and others who do not normally visit museums, and more responsive to the needs of the society. However, defining the value of culture through an emphasis on cultural education, paradoxically, has the potential to undermine the basis of the museum's existence as a public institution. With reference to my research into New Labour's cultural policy, particularly in relation to museums, this paper highlights discourses that have given cultural education a more significant role in the cultural sector. I show how cultural education, with ‘cultural inclusion’ as its main objective, has evolved in the context of an existential crisis in the museum sector over the past 30 years, appearing to offer a means through which they can redefine their role and value in the society as anti‐elitist organisations supporting social change. I then go onto show how this apparent solution to the problem might further undermine the unique value of museums.     

Resurrected pigs,dyed foxes and beloved cows: Religious diversity and nostalgia for socialism in rural Poland

The aim of my paper is to discuss the phenomenon of nostalgia for socialism in rural Poland. More precisely, I discuss how experiences of rurality and diverse religious beliefs intertwine with nostalgia. Depicting the memories of socialism, shared with me by the inhabitants of a multi-religious rural commune in Southern Poland, I aim to demonstrate the ways in which day-to-day experiences of rural life as well as religious diversity contribute to shaping people's remembrances. In order to do so, I describe both the present situation and the historical experiences of the inhabitants of the commune. I introduce representatives of different Christian communities – Roman Catholics, Greek Catholics, Orthodox and Pentecostals – and, by presenting their life stories, I address the issue of how villagers' religious creeds interrelate with the memories and (re)evaluation of the socialist past. My aim here is twofold. Firstly I aim to deconstruct the nostalgia for socialism, showing its complexity and proving that this nostalgia means in fact longing for very concrete experiences of rural life. Secondly, I argue that the study of various religious beliefs and practices is very important for a fuller interpretation of nostalgic discourses and responses to postsocialist transformations.     

The utilitarian criterion,finite sensibility,and the weak majority preference principle

This study is a further analysis of the approach taken by Yew-Kwang Ng to derive the utilitarian criterion. Specific for the model is that individual preferences are finitely sensible. In this framweork an analysis of the consequences on social preferences when different kinds of value premises are imposed is made. It is found that the utilitarian criterion is the unique consequence only for very special choices of the value premise. In addition, uniqueness requires the underlying preferences be cardinal. It is also found that finite sensibility induces approximate cardinalization of preferences.I am grateful to Y.-K. Ng, two anonymous referees and an editor of this journal for helpful and constructive comments on earlier versions of this paper.

Insider/Outsider: A Muslim Woman's Adventure Practicing ‘Alongside’ Narrative Therapy

The following paper centres on my unique experience as a white Australian therapist who is able to sympathise with a Western world view while being immersed in an Islamic world view. The goal is to share my journey as a Muslim Australian via an auto‐ethnography reflexive method. Using diaries, intentional reflexive positioning, and multiple modes of supervision, I contemplate an Islamic identity and value system while negotiating poststructural therapies such as solution‐focused collaborative, and in particular, narrative therapy as viable approaches to working with the Muslim community. There are two inquiries which are of interest. The first is to reflexively describe the experience of being a Muslim practitioner and wondering whether core differences in epistemological views between social constructionism and Islamic doctrine can be overcome. Secondly, this enquiry explores Quranic guidelines about how to perceive ‘problems’ in life, based on the premise that understanding how an Islamic world view addresses life's troubles may add to deeper conceptions of the role of difficulties. I propose that adherent Muslims have a natural metaphorical way of thinking that connects with some of the poststructural therapeutic skills and techniques and at the same time draw on past Quranic solutions for contemporary problems. Little has been written on narrative therapy as a suitable approach to working with Muslim clients. In the current paper I review my personal experience as a veiled Muslim therapist striving to implement narrative therapy alongside an Islamic epistemology.     

Couch Revisited: A Theoretical Treatment of The Information‐Technological Media of Imgur,Reddit, and Twitter

In this paper, I argue that unique locations of digital interactions constitute distinct information‐technological media. I first apply a close reading of Couch's ( 1995a ) work to digital sociology, and then analyze three popular social media networks: www.Imgur.com , www.Reddit.com , and www.Twitter.com . I close with a theoretical application of Couch's paradigm for analyzing the qualities of information technologies.     

Inequality,happiness and relative concerns: What actually is their relationship?

This paper briefly and informally surveys different theoretical models of relative concerns and their relation to inequality. Models of inequity aversion in common use in experimental economics imply a negative relation between inequality and happiness. In contrast, empirical studies on happiness typically employ models of relative concerns that assume that increases in others’ income always have a negative effect on own happiness. However, in these latter models, the relation between inequality and happiness can be positive. One possible solution is a rivalry model where a distinction is made between endowment and reward inequality which have respectively a negative and positive effect on happiness. These different models and their contrasting results may clarify why the empirical relationship between inequality and happiness has been difficult to establish. I would like to thank Ravi Kanbur, Tatiana Kornienko and, especially, Andrew Oswald for very helpful comments. Any errors are mine.     

Strongly consistent game forms

This paper characterizes strongly consistent game forms in terms of power structure and cardinality (i.e. the number of persons, alternatives or strategies). There are three main new results in this paper. First, I give a necessary condition for a game form to be strongly consistent; it is also sufficient in several cases. Second, from the view point of informational requirements and based on the first result, I give a sharp lower bound on the cardinality of each agent's strategy space, for a game form to be strongly consistent and individually rational. Third, I show that the unanimous rule is the unique game form that attains this lower bound for strong implementation of the individually rational Pareto correspondence.     

Public subscription and private contributions

Consider a situation in which individuals post their private contributions for the financing of an indivisible public project. If their valuations for the project are private information, an efficient outcome cannot be guaranteed by just one shot of this procedure (indeed, this is also the case for any one-shot procedure that is individually rational). We focus, therefore, on the dynamic mechanism in which the described procedure is repeated indefinitely, only stopping when the project can be ensured to be inefficient. Under alternative assumptions on the type space, a unique symmetric Perfect Bayesian equilibrium is shown to exist if contributions are restricted to just two possible levels (say, some pre-specified positive contribution or nothing at all). We also show that, except for a limit case, the right decision is eventually reached along this equilibrium, although generally after some (costly but bounded) delay.I have benefited from helpful comments by A. Koffman, M. Perry, L. Corchón, C. Herrero, P. Chander and Francisco Marhuenda. Special mention deserves an anonymous referee whose careful reading of the paper improved it very significantly. The usual caveat applies. I also acknowledge financial support from the Spanish Ministry of Education, CICYT project no. PS90-0156.     

Graph monotonic values

A disturbing feature of most of the solution concepts for TU games with incomplete communication is that payments of players may decrease when they activate a new link. That can be considered as a drawback which does not occur for the Myerson value (Math Oper Res 2:225–229, 1977) of superadditive games. The present article offers a new axiomatic characterization of the Myerson value. We show that the Myerson value is the unique solution for games with communication structures verifying a set of properties including monotonicity with respect to the graph and coinciding with the Shapley value when the communication is complete.
