Strategy-proof division with single-peaked preferences and individual endowments

We consider the problem of (re)allocating the total endowment of an infinitely divisible commodity among agents with single-peaked preferences and individual endowments. We propose an extension of the so-called uniform rule and show that it is the unique rule satisfying Pareto optimality, strategy-proofness, reversibility, and an equal-treatment condition. The resulting rule turns out to be peaks-only and individually rational: the allocation assigned by the rule depends only on the peaks of the preferences, and no agent is worse off than at his individual endowment.

Examining power struggles as a signifier of successful partnership working: A case study of partnership dynamics

In Britain, and Wales particularly, inclusion and equal opportunities for all became key principles guiding the work of the many partnerships that were established at the beginning of this century. A primary objective of this paper is to develop a greater understanding of the politics and processes within ‘partnership’ as a widely used governance instrument. We argue that rather than dismissing partnerships for their exclusionary mechanisms, they might be considered as distinctive ‘arenas of power’ where the emphasis on participation and consensus shapes power relations in particular ways. What we demonstrate, using a differentiated topology of power [Allen, J., 2003. Lost Geographies of Power. Blackwell Publishing], is the effect that different modes of power, at different times, can have on social interaction and the process of partnership working. Although inequality in terms of resources existed in our study, we show that effective partnership working was enhanced at times when more reciprocal modes of power were used. We conclude, therefore, that an analysis of power based on resources alone is limited because the use and effect of resources may be “modified, displaced or disrupted depending upon the relationships that come into play” [Allen, J., 2003. Lost Geographies of Power. Blackwell Publishing, p. 97]. Hence, there is a need for more research on power struggles and conflicts in partnerships over time. Only then it is possible to see how and when differences in resources affect social interaction and result in different levels of (in)equality. A partnership cannot be seen simply as an indirect instrument of a dominant government actor to control organisations and individuals.     

Activation in the Austrian Social Assistance Scheme – Unproductive Pressure and Low Support

Activation is an essential part of social assistance schemes. This article provides an insight into the implementation of activation in the Austrian social assistance scheme by analyzing the work requirements and support offered in two provinces, Upper Austria and Styria. The main questions addressed include: Does social assistance require everyone to look for employment? What kind of requirements do social assistance offices set, what support do they offer and to whom? To what extent do those activation measures lead to a job search? The analysis draws on survey results for 1,071 claimants and recipients in the two provinces. It is shown that social assistance does not require all respondents to search for employment, and that activation actually depends on province as well as personal circumstances. Items are formed by identifying low and high conditionality in terms of support and pressure based on 11 questions. Current practice incorporates supportive forms of activation to a lesser degree than efforts to force people to find work, due to pressures from the caseworker. Although high conditionality is not found to affect the job search activity, the job search requirement itself fosters people's search for employment.     

Stability and Nash implementation in matching markets with couples

We consider two-sided matching markets with couples. First, we extend a result by Klaus and Klijn (J Econ Theory 21: 75–106, 2005, Theorem 3.3) and show that for any weakly responsive couples market, there always exists a “double stable” matching, i.e., a matching that is stable for the couples market and for any associated singles market. Second, we show that for weakly responsive couples markets, the associated stable correspondence is (Maskin) monotonic and Nash implementable. In contrast, the correspondence that assigns all double stable matchings is neither monotonic nor Nash implementable.     

Führungskulturen an der Universität: Feedbackinstrumente als Schlüssel zur Personalentwicklung

Management culture at German universities. Guided feedback as an instrument to develop leadership skills In future, universities will be fundamentally more exposed to national and international competition than they are today. The challenges for Germany’s universities arising from this are increased by the reform pressure towards a modernization of the governmental administration. On grounds of these new tasks and challenges, inner-organizational changes as well as the development of a leadership responsibility and further training of the employees’ social skills are necessary. Therefore up-to-date personnel development belongs to a university’s modernization program. At the Berlin University of Technology appraisals by subordinates are practiced in order to design a fair leadership culture. The crucial factor for this is the professor’s and administration manager’s identification with their leadership role. For a further process consultation the adoption of coaching is recommended.     

Under the Rainbow Flag: Webbing Global Gay Identities

This essay analyzes contemporary global and local constructions of gay identities on World Wide Web sites. The authors rely on core cultural symbol analysis and visual imagery content analysis in their rhetorical-critical examination of texts and images. Three heavily trafficked, U.S.-domained Web sites are analyzed first, acknowledging the hegemonic positioning of U.S. cultural space as a physical, ideological, and cyber realm that enables the coming out process but also a realm in which cultural imperialism and commodification of other experiences reign. By comparing and contrasting the analyses of these sites with gay, lesbian, bisexual, and transgender sites originating in Mainland China, Japan, and Germany, the authors document both the transformative and empowering aspects of transnational identity constructions and the dynamics of localized constructions that take part in, support, negotiate, and resist such global constructions.     

Disco clothing, female sexual motivation, and relationship status: is she dressed to impress?

The relationship between a female's clothing choice, sexual motivation, hormone levels, and partnership status (single or not single, partner present or not present) was analyzed in 351 females attending Austrian discotheques. We digitally analyzed clothing choice to determine the amount of skin display, sheerness, and clothing tightness. Participants self-reported sexual motivation, and we assessed estradiol and testosterone levels through saliva sampling. Results show that females are aware of the social signal function of their clothing and that they in some cases alter their clothing style to match their courtship motivation. In particular, sheer clothing -although rare in the study- positively correlated with the motivation for sex. Hormone levels influenced clothing choice in many groups, with testosterone levels correlating positively with physique display. In females who had a partner but were at the disco unaccompanied by the partner, estradiol levels correlated positively with skin display and clothing tightness. Significant differences were not found, however, for clothing choice across the partnership-status groups.     

Parental leave benefit in Austria. Stratified take-up in a conservative country

Since 2000, parental leave benefit legislation has shifted from an employment-related benefit to a nearly universal and then to a mixed system of five different benefit rates of income-related and flat-rate models with four different maximum lengths, and with a longer spell if two partners share childcare leave in Austria. The diversification leads to the questions: what determines parents' choice of a certain model, and what are the implications of such a diverse system for social and gender equality? The parents' choice depends on income, employment status, region, and relationship status and thus is restrained. The models further social and gendered stratification, as they still serve a conservative male breadwinner family as well as a modernised dual breadwinner one and, to a lesser degree, an adult worker. In contrast, low-income (single) parents receive more individualised treatment and have to engage in employment sooner than other groups.     

Consistency and population sensitivity properties in marriage and roommate markets

We consider one-to-one matching markets in which agents can either be matched as pairs or remain single. In these so-called roommate markets agents are consumers and resources at the same time. Klaus (Games Econ Behav 72:172–186, 2011) introduced two new “population sensitivity” properties that capture the effect newcomers have on incumbent agents: competition sensitivity and resource sensitivity. On various roommate market domains (marriage markets, no-odd-rings roommate markets, solvable roommate markets), we characterize the core using either of the population sensitivity properties in addition to weak unanimity and consistency. On the domain of all roommate markets, we obtain two associated impossibility results.
