Abstract Aggregations and Proximity Preservation: An Impossibility Result

An impossibility result for completely abstract social aggregation rules is presented. It is shown that non-imposition and a new no-veto property (two properties in the spirit of the Pareto principle and non-dictatorship respectively) are incompatible with an inter-profile consistency condition formulated in terms of proximity preservation.The result in this paper has been presented in the Staff Seminar at the University of Graz and at the 2001 Meeting of the Public Choice Society in San Antonio. We are grateful to all participants, especially Hannu Nurmi and Don Saari, and to an anonymous referee for helpful comments.     

Maybe Bacon Had a Point: The Politics of Interpretation in Collective Sensemaking 1

Despite major contributions to theories of organizational knowledge from socially situated, practice‐based approaches, there remains a blind‐spot in this literature concerning power and politics. This paper makes some initial attempts to address this absence by thinking about how far alternative theories of power/knowledge can strengthen and extend practice‐based approaches to knowledge. The need for a detailed analytic of the multiple techniques, strategies, and expressions of power/knowledge in concrete social situations and the different ways in which they come together through specific episodes of enactment is highlighted. To illustrate this, we draw on an ethnographic study of an inter‐organizational collaboration in the telecommunications sector. This illustration focuses on struggles over meaning during a problem‐solving encounter during the later stages of a project for developing and implementing new software for telephone exchanges.     

World Class Manufacturing: Further Evidence in the Lean Production Debate1

This paper reports the results of a study into the performance and management practices of 18 autocomponents plants, nine of which were located in the UK and nine in Japan. The study compared the performance of these plants and used quantitative measures to test the use of lean production techniques among the high performers. Five plants displayed high performance on measures of both productivity and quality. All of these were located in Japan. Several measures of management practice provided some support for the lean production model, particularly in the area of process discipline and control; measures of human resource management policy and work organization proved less significant. Contextual factors pointed to the conditions necessary to support lean production; higher performing plants had more stable demand and lower absenteeism.     

Sexually Open Marriage

In this article the author describes sexually open marriage in the lives of 71 individuals. These persons make up three groups—persons in open relationships, persons divorced or separated after an open relationship and secondary partners of persons in open relationships—and are described as they experience their open relationships and then, two years later, as they evaluate the changes in their open sexual relationships. Similarities and differences among these three groups are discussed. In addition, this article looks at the ground rules that are established, jealousy issues and their management, and it discusses the role of equity and equality in sexually open relationships.     

Detecting ongoing intimate partner violence in the emergency department using a simple 4-question screen: the OVAT

We wanted to prospectively evaluate the use of a brief screening tool for ongoing intimate partner violence (IPV), the OVAT, and to validate this tool against the present Index of Spouse Abuse (ISA). The design was a prospective survey during randomized 4-hour shifts in an urban emergency department setting. The scale consists of four questions developed based on our previous work. The ISA was compared as the gold standard for detection of present (ongoing) IPV. Of 362 eligible patients presenting during 75 randomized 4-hour shifts, 306 (85%) completed the study. The prevalence of ongoing IPV using the OVAT was 31% (95% CI 26% to 36%). For the ISA, the prevalence was 20% (95% CI 16% to 25%). Compared with the ISA, the sensitivity of the OVAT in detecting ongoing IPV was 86%, specificity 83%, negative predictive value 96%, positive predictive value 56%, with an accuracy of 84%. In conclusion, four brief questions can detect ongoing IPV to aid in identifying the victim.     

Impugning the Humanitarian Defence

This article examines the claim that democratic states are justified in restricting access to asylum seekers on the grounds that failing to do so reduces public support for humanitarian refugee policies – referred to here as the humanitarian defence. Drawing on detailed historical, comparative and interpretive analysis of migration policy in Canada and Australia, the author builds on Matthew Gibney’s development of practically guided normative theory to assess cases in which political elites may legitimately enact restrictive policies in response to strong public opposition. Challenging the normative basis of the humanitarian defence, the article engages in a detailed discourse analysis of asylum crises in Canada (1987, 1999) and Australia (1979, 2001). The findings suggest that political elites do not respond to an independently arrived at, and objectively established, public opinion as implied in the humanitarian defence. Rather, political elites play a crucial role in shaping the discourse on asylum seekers and consequently, influence the very “public opinion” to which they claim to be responding. The author concludes that political elites should attempt to foster an environment in which the public accepts international obligations to refugees but accepts that in some cases political elites may be justified in implementing restrictive measures.     

Contract,Mechanism Design,and Technological Detail

This paper develops a theoretical framework for studying contract and enforcement in settings with nondurable trading opportunities and complete but unverifiable information. The framework explicitly accounts for the parties' individual trade actions. The sets of implementable state‐contingent payoffs, under various assumptions about renegotiation opportunities, are characterized and compared. The results indicate the benefit of modeling trade actions as individual, rather than as public, and they highlight the usefulness of a structured game‐theoretic framework for applied research.
