This paper studies the role of transfer fees in professional sports, where players can commit to binding long‐term contracts. They cannot switch clubs before their contract expires unless the old club agrees to let them go; the transfer fee is the price of that agreement. Transfer fees have been defended as a necessary incentive for clubs to invest in training their young players. The apparent absence of significant training costs (compared to the level of transfer fees) has undermined this defense. We present a model without training where an industry of clubs with heterogeneous marginal revenue products for player ability and a population of players with various levels of talent and experience match. Transfer fees are needed to allocate scarce playing opportunities efficiently among players of different levels of known and potential ability. We show that total surplus is lower without transfer fees because playing time gets reallocated towards older players with less upside potential. The resulting increase in player salaries exceeds the transfer fee costs for each level of ability. (JEL: J31, J41, K12, L83) 相似文献

The relationship between mother and daughter is unlike other family dyads and important to both parties over a lifespan. One underexplored area of this relationship is how adult daughters construct and perform the daughtering role. The present study explores how daughters talk about the ways they enact daughtering and evaluate their role in a social world. The findings reveal how daughters position themselves within a family system and, more broadly, in society. This paper includes interview data with 33 adult daughters about their mothers. We illuminate more about how daughters, as role players, conceive of the expectations for their roles and evaluate their role performance in light of role expectations. Analysis revealed four role expectations tied to good daughtering: showing respect, providing protection, eliciting mothering, and making time for connection. Our analysis supports that daughters assess themselves based on their understanding of these role expectations. We present a matrix to illustrate these findings. 相似文献

This article reports on Participatory Action Research with social work practitioners who collaboratively explored the effects on professional practice when practitioners raise their awareness of an ecosocial work approach. Although contemporary research in the profession has contributed to the ongoing development of ecosocial work, there is a notable lack of collaboration with social work practitioners. Using a transformative ecosocial work model of practice, researchers together with social workers from a range of practice contexts met as co‐inquirers to plan, implement and evaluate ecosocial work interventions. As part of a larger international study, this article reports on research outcomes within the Australian context. Overall, results indicate that practitioners incorporated interventions across personal, individual, group and organisational levels of practice, but were constrained by structural elements at broader levels. Continuing the development of ecosocial work requires further collaborative exploration with practitioners, which takes into consideration communities and broader social and political systems. Key Practitioner Messages: ? This research endeavours to contribute to the evidence‐base for progressing transformative ecosocial work in professional practice; ? Using Participatory Action Research (PAR), this research was done in collaboration with social work practitioners as co‐inquirers to develop ecosocial work interventions; ? A range of ecosocial work interventions were implemented at the personal, individual, group and organisational levels. 相似文献

To examine children's ability to control their affective expression facially, 68 second- and fourth-grade boys and girls were unobtrusively videotaped while discussing six self-chosen activities about which they felt positively, neutrally, or negatively. Children then performed three facial management tasks: (a)inhibition (showing no emotion instead of a felt emotion); (b)simulation (showing an emotion when not feeling anything); and (c)masking (showing an emotion that is different than what is felt). Twelve raters judged the edited tapes of the children's performance for affect positivity and deceptiveness. Repeated measures ANOVAs indicated, in contrast to previous research, that children were highly competent in managing facial displays. To understand children's techniques for managing affective displays, two raters categorized the primary cognitive strategies children used. Results showed that fourth graders used more complex strategies more often than second graders. These results highlight children's skill and strategies in affect management.Funding for this project was provided by a NICHHD grant (#HD22367) to the first author. We gratefully acknowledge the assistance of Nancy A. Ballard and Michael G. Rakouskas in data collection and preparation. We also thank the children whose participation and cooperation made this research possible. 相似文献

Shift work has been reported to predict health problems, and a possible explanation is that shift work may lead to poorer health habits, thereby increasing a person's vulnerability to illness. This study examined the association between shift work and health habits, as indicated by smoking, alcohol intake, physical activity and by being overweight. A questionnaire was sent to all 2795 female nurses working in the 10 hospitals of two Finnish health care districts. From the 2299 respondents, we selected those 506 shift workers who reported having always done shift work and those 183 day workers who had never done shift work. Shift workers were found to smoke more and to be overweight more often than day workers. These differences gradually increased in each successive age group, being 1.94 pack-years in smoking and 0.9 kg m-2 in body mass index among nurses over 45 years of age. Shift work was not associated with alcohol intake or sedentary lifestyle. This evidence is compatible with the possibility that shift work in nurses increases smoking and being overweight to a degree that contributes to health problems, including coronary heart disease. 相似文献

An important requisite for improving risk communication practice related to contentious environmental issues is having a better theoretical understanding of how risk perceptions function in real‐world social systems. Our study applied Scherer and Cho's social network contagion theory of risk perception (SNCTRP) to cormorant management (a contentious environmental management issue) in the Great Lakes Basin to: (1) assess contagion effects on cormorant‐related risk perceptions and individual factors believed to influence those perceptions and (2) explore the extent of social contagion in a full network (consisting of interactions between and among experts and laypeople) and three “isolated” models separating different types of interactions from the full network (i.e., expert‐to‐expert, layperson‐to‐layperson, and expert‐to‐layperson). We conducted interviews and administered questionnaires with experts (e.g., natural resource professionals) and laypeople (e.g., recreational and commercial anglers, business owners, bird enthusiasts) engaged in cormorant management in northern Lake Huron (n = 115). Our findings generally support the SNCTRP; however, the scope and scale of social contagion varied considerably based on the variables (e.g., individual risk perception factors), actors (i.e., experts or laypeople), and interactions of interest. Contagion effects were identified more frequently, and were stronger, in the models containing interactions between experts and laypeople than in those models containing only interactions among experts or laypeople. 相似文献

This paper presents in-depth case study of a successful hybrid political and community organizing campaign to ensure equitable access to health care through the perspective of a grassroots San Francisco community-based organization, the Chinese Progressive Association (CPA), which has been organizing low-income Chinese immigrants for over four decades. First, it outlines the Health Care Security Ordinance (HCSO), which, since its passage in 2006, has established a near-universal health care access program, helping to make health care accessible and affordable to individuals living and working in San Francisco. Then it presents the campaign to save the HCSO, focusing on CPA’s participation in the HCSO coalition. Finally, it discusses health care as it relates to the San Francisco’s affordability crisis and the political economic context in which it is taking place. Despite the limitations inherent in small case studies like this one, it nevertheless provides a valuable opportunity to better understand how one politically progressive city attempted to address the problem of grossly inequitable health care access through the lens of community organizing, advocacy, and coalition building. San Francisco, like many major American cities today, is being confronted with rapid gentrification and growing economic inequality—the backdrop to the HCSO. Through innovative experiments in social responsibility like the HCSO, however, the city has made leaps in health care access. It concludes with lessons learned from local organizing and advocacy to save the HCSO as these may inform other local efforts to promote health care for all. 相似文献
