Entry deterrence in electoral spatial competition

 In this paper we examine a model of electoral competition with entry costs, where several established parties compete against each other under the threat of potential entry. Assuming single-peakedness of the distribution of voters’ ideal points, we show that, if there are two established parties, an equilibrium always exists and is unique, and demonstrate that the Hotelling-Downs and the Smithies-Palfrey equilibria represent special cases of the equilibrium in our model. If there are more than two established parties, an equilibrium is always unique and there exists an upper bound on the values of entry cost which guarantee the existence of an equilibrium.

A note on the core and von Neumann-Morgenstern solutions of simple games

Following the results of Nakamura (1979) and Muto (1984), we derive, for a given proper voting game G, the upper bound on the size of the space of alternatives, which guarantees that the core constitutes a von Neumann-Morgenstern solution for any profile of voter's preferences. In particular, we show that if the space of alternatives consists of more than two elements, then, in general, the core is not a von Neumann-Morgenstern solution.We wish to thank Bezalel Peleg for pointing us out that one of the results in the previous version of this paper has already been proved by Muto (1984) and two anonymous referees for their useful remarks.     

Men who use violence: intimate violence versus non-intimate violence profiles

The current study examined the differences between three types of violent men based on Holtzworth-Munroe and Stuart's (1994) tripartite typology and a group of non-intimate violent men. First, a cluster analysis was conducted on a sample of 91 domestically violent men, resulting in three clusters that approximated the tripartite model for psychopathology as measured by the MMPI-2, that is, non-pathological, borderline/dysphoric, and antisocial. Based on the violence variables (i.e., severity of violence, family-only violence, and exposure to family of origin violence) only severity of violence approximated what would be expected across the three clusters, that is, the less the psychopathology, the less severe the violence. The other two violence variables had approximate frequencies/percentages of occurrence that would be expected for individual typologies with some but not all three typologies. In comparing the three intimate violent typologies to the non-intimate violent group, the non-intimate and non-pathological groups were within normal limits and did not differ significantly on any of the MMPI-2 scales. These non-intimate and non-pathological groups differed significantly from the antisocial and borderline/dysphoric groups on all the scales that defined the psychopathology of these two groups. On the violence variables, the non-intimate groups reported significantly less severe violence than the borderline/dysphoric and antisocial groups.     

25 Health care trends. What's hot,what's not,and what does the future hold

As we usher in 2003, America's health care system remains in a chaotic state. Will managed care live or die? Will quality improvement efforts pay off? Are we ready for the next bioterrorism attack? Will the shortage of physician soon rival the shortage of nurses? To help gauge where health care stands today and what the future holds, The Physician Executive asked doctors who serve on ACPE's peer review panel to list the hottest health care trends in the U.S right now. Then, we took the list to three respected health care futurists -- Leland Kaiser, PhD, Jeff Goldsmith, PhD, and Russel Coile, MBA -- and asked them for their insights on the trends. Yes, Kaiser, Goldsmith and Coile are opinionated. Yes, they're controversial. But no matter whether you agree or disagree with their views, the three health care futurists' comments could spark discussions that will help shape U.S. health care this year and beyond. The trends are presented in no particular order.     

Managerial value orientations: A typology and assessment

This paper presents a comprehensive assessment of managers' values by extending Milton Rokeach's theory of values. Through an assessment of previous value studies, a typology of managerial value orientations is developed. This classification will assist future value researchers in developing a priori testable hypotheses regarding managerial value preferences and in measuring managers' values within the context of a value orientation. Modifications to the Rokeach Value Survey are used to enhance the analysis and application of the study of values to organizational settings. Behavioral implications of these findings are explored in the context of managerial decision making in a business organization.     

The Uses and Abuses of Co-Therapy

The literature on co-therapy suggests increased interest in this treatment procedure. There is some agreement over advantages and disadvantages, but there is also confusion on indications and counter-indications. This paper summarizes the current use and abuse of co-therapy. The reported clinical experiences of several co-therapist teams, including spouse co-therapists, are also discussed. It appears that co-therapy will remain controversial until outcomes are rigorously measured and compared with the results of other therapeutic modalities in a standardized, acceptable way.     

Corporate Volunteering: Benefits and Challenges for Nonprofits

In the frame of corporate social responsibility, corporate volunteering is almost exclusively studied from the point of view of companies, while the perspectives of nonprofit organizations are neglected. Hence, this article focuses on the perspective of managers of nonprofit organizations on volunteer partnership projects with for‐profit companies. In the center of this article lie nonprofit managers' strategy and motivation for participating in corporate volunteering, conception of corporate volunteer activities, and the often‐cited win‐win‐win aspect. Key findings suggest that a majority of the questioned nonprofits lack strategic behavior and management tools for undertaking volunteer partnership projects with companies. Nevertheless, corporate volunteering is widely perceived as an opportunity and a promising method of raising donations for nonprofit organizations. This article suggests that the key to successful future cooperation between nonprofits and profit‐oriented organizations lies in the processes of internal evaluation and subsequent strategy development.     

Do the DSM-5 diagnostic revisions affect the psychometric properties of the Brief Biosocial Gambling Screen?

Several significant changes in the diagnostic criteria for gambling disorder occurred with the newest revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The changes aim to simplify and streamline the diagnosis without compromising its validity. Yet many of the tools used to screen and diagnose the disorder are based upon the prior fourth edition of the DSM, and it is unclear how they perform with the revised diagnostic criteria. The aim of this study is to examine the psychometric properties of a common pathological gambling screen, the Brief Biosocial Gambling Screen (BBGS; Gebauer, LaBrie, & Shaffer, 2010), in the context of DSM-5 criteria within a help-seeking sample. Gamblers calling a helpline (N = 2750) completed a semi-structured interview assessing DSM-IV past-year pathological gambling criteria with a trained clinician. Sensitivity, specificity, positive predictive value, negative predictive value and differences by sex were examined. The BBGS had high sensitivity as well as positive and negative predictive values. In light of the revisions made to the diagnostic criteria in DSM-5, the BBGS remains a psychometrically supported instrument for gambling disorder.     

Not without my sister(s)

Less than two months after 11 September 2001, and a few weeks after the beginning of the US bombing campaign in Afghanistan, President George W. Bush made an urgent plea to see Iranian filmmaker Mohsen Makhmalbaf's Kandahar. Not only did the President want to see Kandahar; he encouraged US citizens to view it as well. This article offers two readings of Kandahar – the first suggestive of what its filmmaker Makhmalbaf saw in Afghanistan and the second suggestive of what Bush saw (or hoped to see) in Makhmalbaf's Afghanistan. In particular, this article focuses on how the Bush administration – against the intentions of Kandahar's director and star – propelled occidental subjects to ‘lift the veil’ on Afghanistan and on Afghan women by viewing Kandahar as if it positioned the feminine as a needy and willing object of US rescue. It was in part by laying this particular claim to the separated sisters of Kandahar that the Bush administration constructed a humanitarian US ‘we’ as among the foundations of its ‘moral grammar of war’ in the war on terror.
