This paper uses a natural experiment to document the impact of social pressure on voting behavior. The main hypothesis is that social pressure creates incentives to vote for the purpose of being seen at the voting act. This incentive is particularly high in small and close‐knit communities. Empirically, I analyze the effect of postal voting on voter participation in Switzerland. Optional postal voting decreased the voting costs, but simultaneously removed the social pressure to vote. In spite of the large reduction in voting costs, the effect on aggregate turnout was small. However, voter participation was more negatively affected in the smaller communities. This lends support to the view that social incentives played a role for certain people's voting decisions. (JEL: H0, Z13)  相似文献

Constructive-developmental theory is a stage theory of adult development that focuses on the growth and elaboration of a person's ways of understanding the self and the world. In this article we review how the constructive-developmental frameworks of Kegan [Kegan, R. (1982). The evolving self: Problem and process in human development. Cambridge, MA: Harvard University Press], Torbert [Torbert, W. R. (1987). Managing the corporate dream: Restructuring for long-term success. Homewood, IL: Dow Jones-Irwin.], and Kohlberg [Kohlberg, L. (1969). Stage and sequence: The cognitive developmental approach to socialization. In D. Goslin (Ed.), Handbook of socialization: Theory and research. New York: Rand McNally] have been applied in the theoretical and empirical literature on leadership and management. Although the literature has produced a number of propositions, the notion that a leader's order of development should impact his or her leadership effectiveness or managerial performance has generated the most research. We found mixed support for this proposition as well as a number of limitations in the research in general. To have a greater impact on the leadership field, constructive-developmental theory needs to generate more robust research, to link more clearly with on-going streams of leadership research, and to explore the contribution of aspects of the theory beyond individual order of development.  相似文献

This paper deals with the classical problem of density estimation on the real line. Most of the existing papers devoted to minimax properties assume that the support of the underlying density is bounded and known. But this assumption may be very difficult to handle in practice. In this work, we show that, exactly as a curse of dimensionality exists when the data lie in Rd, there exists a curse of support as well when the support of the density is infinite. As for the dimensionality problem where the rates of convergence deteriorate when the dimension grows, the minimax rates of convergence may deteriorate as well when the support becomes infinite. This problem is not purely theoretical since the simulations show that the support-dependent methods are really affected in practice by the size of the density support, or by the weight of the density tail. We propose a method based on a biorthogonal wavelet thresholding rule that is adaptive with respect to the nature of the support and the regularity of the signal, but that is also robust in practice to this curse of support. The threshold, that is proposed here, is very accurately calibrated so that the gap between optimal theoretical and practical tuning parameters is almost filled.  相似文献

The article describes the technology transfer concerns reported by a small sample (N=14) of recent college graduates with disabilities. In structured, in-depth interviews, researchers asked respondents to reflect on the extent to which they had utilized technology resources during their college years in preparation for the world of work. Results suggest that colleges and universities need to play a more active role in introducing students with disabilities to both generalized and assistive technology services.  相似文献

As the numbers of caregivers continue to increase, more attention is being focused on the unique stresses these individuals experience. Caring for a loved one tests the limits of even the most resilient, regardless of professional status or experience. Laughter is a universal elixir which allows people to cope more sanely with stress and caregiving responsibilities. Research on the emotional and physical benefits of laughter supports the use of humor by professionals and family members who occupy caregiving roles. This article addresses this research and examines common caregiver emotions while providing concrete guidelines for developing humor. Case examples demonstrate how laughter and wit are utilized by those caring for a loved one.  相似文献

1. Removing barriers to graduate psychiatric nursing education is possible by delivering courses via the Internet. 2. The Internet is full of valuable resources for graduate psychiatric nursing education. 3. Successful online learning environments involve a paradigm shift on the part of faculty from traditional teaching to facilitating the learning of adult students. 4. Increasing the number of advanced practice psychiatric nurses through Web-based education will transform the delivery of mental health care.  相似文献

This article reviews the literature pertaining to the causes of child maltreatment. The review discusses 68 articles from various disciplines and organizes them into four predominant theories; psychodynamic, social learning, social psychological, and sociological. Research evidence supporting each of the theories is described and critiqued.  相似文献

Alcohol- and substance-related diagnoses were examined as factors in child to adult sexual revictimization. Three hundred community women completed interviews and self-report instruments to obtain information regarding victimization and to diagnose substance use disorders (alcohol and substance abuse/dependence). Childhood sexual abuse (CSA) survivors were more likely than nonvictims to meet criteria for both substance use disorders and to report rape (e.g., unwanted intercourse due to threat or use of force, or due to the inability to consent due to the respondent's alcohol or drug use) and coerced intercourse (e.g., unwanted intercourse due to verbal coercion or misuse of authority by the perpetrator) by acquaintances, strangers, and husbands. In general, both CSA and substance use disorders were predictive of adult sexual victimization, but there were no significant interactions between these factors. Overall, substance use disorders were related to rape for all women; this relationship was not unique to CSA survivors. Alcohol- and substance-related diagnoses predicted rape by all three types of perpetrators, but CSA was predictive of rape only by acquaintances and strangers and not husbands. In contrast, CSA predicted coerced intercourse by all three perpetrators, while alcohol- and substance-related diagnoses predicted coerced intercourse by acquaintances and strangers, but not husbands. Results highlight the need to continue the study of revictimization of CSA survivors, including examination of both rape and sexually coercive experiences by different types of perpetrators. Findings support continued research of substance use disorders as risk factors for sexual victimization among all women.  相似文献
