This longitudinal study examines how extracurricular activity involvement contributes to "educational resilience"—the unexpected educational attainments of adolescents who are otherwise vulnerable to curtailed school success due to personal- and social-level risks. Educationally vulnerable youth characterized by significant risks and an absence of assets were identified during early adolescence (approximately age 14) using measures of academic motivation, achievement, and mental health as well as family, school, and peer contexts. Using a mixture of variable- and pattern-centered analytic techniques, we investigate how both the total amount time that vulnerable youth spent in positive extracurricular activities and the specific pattern of their extracurricular activity involvement during late adolescence (approximately age 17) predict their subsequent enrollment in college during early adulthood (up through approximately age 21). Educational resilience was predicted uniquely by some, but not all, activity patterns. These results suggest that positive extracurricular activity settings afford vulnerable youth developmentally appropriate experiences that promote educational persistence and healthy development .  相似文献

The traditional formulation of the altruism model has altruistic terms that relate solely to other parties’ felicities from consumption. But if those others are altruistic as well, their altruism benefits are being neglected. Total altruism takes the total utilities of others, rather than their mere felicities, as the basis for altruistic valuations. We assess total altruism in an intergenerational world. Perfect altruism, a concept due to Ramsey (Econ. J. 38(152):543–559, 1928), requires that a generation value itself relative to its successor as it would any two consecutive generations. Total altruism and perfect altruism prove to be incompatible concepts. Total altruism is only meaningful when there is some generational selfishness. The analysis considers both forward-looking and forward and backward-looking altruism.  相似文献

The problem of patient no‐shows (patients who do not arrive for scheduled appointments) is significant in many health care settings, where no‐show rates can vary widely. No‐shows reduce provider productivity and clinic efficiency, increase health care costs, and limit the ability of a clinic to serve its client population by reducing its effective capacity. In this article, we examine the problem of no‐shows and propose appointment overbooking as one means of reducing the negative impact of no‐shows. We find that patient access and provider productivity are significantly improved with overbooking, but that overbooking causes increases in both patient wait times and provider overtime. We develop a new clinic utility function to capture the trade‐offs between these benefits and costs, and we show that the relative values that a clinic assigns to serving additional patients, minimizing patient waiting times, and minimizing clinic overtime will determine whether overbooking is warranted. From the results of a series of simulation experiments, we determine that overbooking provides greater utility when clinics serve larger numbers of patients, no‐show rates are higher, and service variability is lower. Even with highly variable service times, many clinics will achieve positive net results with overbooking. Our analysis provides valuable guidance to clinic administrators about the use of appointment overbooking to improve patient access, provider productivity, and overall clinic performance.  相似文献

According to the constant growth model and perceived finance theory, the cost of new external equity exceeds the cost of retained earnings due to flotation costs and underpricing. Carlson and Dietz [1] have recently argued that the constant growth model is operationally inadequate whenever the net proceeds from the issuance of a new share differ from book value. Specifically, they contend that the cost of new external equity is less than the cost of retained earnings whenever the net proceeds from a new share exceed book value. We show that these conclusions stem from an error in interpretation and therefore that the constant growth model is valid regardless of the relationship between market prices and book value.  相似文献

This paper contrasts direct election with political appointment of regulators. When regulators are appointed, regulatory policy becomes bundled with other policy issues the appointing politicians are responsible for. Because voters have only one vote to cast and regulatory issues are not salient for most voters, there are electoral incentives to respond to stakeholder interests. If regulators are elected, their stance on regulation is the only salient issue so that the electoral incentive is to run a pro‐consumer candidate. Using panel data on regulatory outcomes from U.S. states, we find new evidence in favor of the idea that elected states are more pro‐consumer in their regulatory policies. (JEL: H1, K2)  相似文献

Research interest in extreme contexts was growing before the COVID-19 pandemic and has intensified since. The climate crisis, significant geo-political conflict, political polarization and upheaval, and economic/financial crises that present existential challenges to organizations have all contributed to rising interest in extreme-context research. COVID-19 itself has generated an enormous body of research across all sub-fields of management. However, the substantive, methodological and conceptual implications of this large volume of research remain unclear. In this introduction to the British Journal of Management COVID-19 Online Virtual Issue, we describe and analyse COVID-19 research so far published in the British Journal of Management. The Journal was proactive in seeing the profound implications of COVID-19 for management research and practice, issuing an early call for contributions, and publishing several exploratory commentaries as early as July 2020. In this paper, we situate COVID-19 research within the broader extreme-context research, analyse contributions made so far, and build upon an extended taxonomy of extreme contexts to suggest ways for future research to generate further impactful insights.  相似文献

The authors sought to test work-family conflict (WFC) theory by examining how family relationships may influence WFC, social self-efficacy, and self-esteem. They developed and tested a structural model of the relationship between family career influence and self-esteem through the mediating variables of anticipated emotion-based WFC, behavior-based WFC, and the cognitive variable of social self-efficacy. Data were collected from 301 college students (208 women, 93 men) and analyzed using structural equation modeling. Results indicated that family career influence positively related to college students' self-esteem through the mediating variables of social self-efficacy and emotion-based WFC. Behavior-based WFC did not function as a mediating variable. When focusing on issues related to students' self-esteem, career counselors should address ways that family influences anticipated emotion-based WFC and use interventions designed to increase social self-efficacy. Future researchers should consider and test additional mediating factors that may help explain how the dimensions of WFC relate to self-esteem.  相似文献

Common factors proponents discuss the benefits and methods of including common factors in marriage and family therapy (MFT) training; yet there are no empirical investigations of how common factors are incorporated into MFT curricula. The purpose of this study was to obtain a baseline understanding of common factors' role in MFT training. Thirty‐one directors of COAMFTE‐ and CACREP‐accredited MFT training programs responded to a survey about the inclusion of common factors in their training program, as well as the benefits, challenges, and students' reactions to common factors training. Findings show that common factors are regularly included in MFT training programs and have garnered largely positive responses. Additional results are discussed regarding the implications of common factors in MFT training.  相似文献
