A meningococcal serogroup B (MenB) outbreak at a large public university prompted an emergency response to immunize undergraduates. Objective: To report on a successful meningococcal serogroup B (MenB) vaccine clinic response at a large public university. Methods: We assembled the team leaders to write this case report. Results: Activation of the emergency plan and points of dispensing required cooperation of many units on campus under the leadership of university health officials with support from Centers for Disease Control and Prevention, state division of public health and the city-county health department. Significant efforts to provide consistent messages to students and parents regarding the outbreak and the availability of the MenB vaccines were made. Volunteers were recruited to staff the clinics alongside university healthcare providers. Over 22,000 doses of vaccine were administered. Conclusion: We report our experience and lessons learned which may be helpful to universities in preventing and responding to disease outbreaks.  相似文献

Abstract

Grubbs and Weaver (1947 Grubbs, F. E., and C. L. Weaver. 1947. The best unbiased estimate of population standard deviation based on group ranges. Journal of the American Statistical Association 42 (238):22441. doi: 10.2307/2280652.[Taylor & Francis Online], [Web of Science ®] [Google Scholar]) suggest a minimum-variance unbiased estimator for the population standard deviation of a normal random variable, where a random sample is drawn and a weighted sum of the ranges of subsamples is calculated. The optimal choice involves using as many subsamples of size eight as possible. They verified their results numerically for samples of size up to 100, and conjectured that their “rule of eights” is valid for all sample sizes. Here we examine the analogous problem where the underlying distribution is exponential and find that a “rule of fours” yields optimality and prove the result rigorously.  相似文献

Although psychological approaches have been the mainstay of scholarly research on school climate, offering state-of-the-art measurements and methodologies, sociological perspectives remain essential perspectives because violence is essentially a social phenomenon. This paper offers a theoretical consideration of contributions to this field, focusing specifically on those that provide a critical historical lens. I suggest that while Foucault's approach to the disciplining of docile bodies and self-restraint offers crucial conceptual tools, Norbert Elias's work—which is scarce in scholarly research on school climate—provides a complementary but necessary framework for understanding emotional and relational aspects of peer harassment.  相似文献

There is mixed evidence in the existing literature on whether children are associated with greater subjective well-being, with the correlation depending on which countries and populations are considered. We here provide a systematic analysis of this question based on three different datasets: two cross-national and one national panel. We show that the association between children and subjective well-being is positive only in developed countries, and for those who become parents after the age of 30 and who have higher income. We also provide evidence of a positive selection into parenthood, whereby happier individuals are more likely to have children.  相似文献

This study explores the significance of food and mealtimes in relation to the transition into foster care and the therapeutic settling of the child in a new family. In doing so, we draw upon an in‐depth, qualitative case study of 10 experienced foster families in the UK focusing on what helped them to be successful. At the time of the study, there were 16 foster children, aged 9–16, living with the families. Data collection included semi‐structured qualitative interviews and audio‐diaries with all family members who wished to be involved as well as eco‐maps produced by the young people. Thematic analysis and data extracts are reproduced in the study to demonstrate that meals and food preferences can function to affirm identities, membership and boundaries of family life as well as provide a site of conflict and control.  相似文献

Spanish-speaking and culturally sensitive social workers are in high demand throughout the country to work with Latino clients. Latinos currently represent about 11% of active social workers, limiting the capacity of social work to effectively address the needs of the Latino population. Despite this shortage, little attention has been paid to the recruitment and retention of Latinos in social work. This article presents a case study that examines a BSW program accredited by the Council on Social Work Education, at a bilingual, private college where 90% of students self-identify as Latinos. It details how the BSW program builds on the students’ community cultural wealth to ensure continued recruitment and retention of Latino students. Implications for social work education are discussed.  相似文献

In this reply to the commentaries, we note several points of disagreement with Johnson and Greenman on theoretical and empirical grounds. We are particularly surprised by their assumption that attachment has already been established as the key mechanism of change in couple therapy, as our present findings do not support this idea. We also elaborate on Gurman's functional contextualist views and describe why IBCT may be a particularly helpful model for training new couple therapists in a contextualist way.  相似文献

In recent decades a substantial shift in landownership has taken place in rural America as millions of acres of land have come under the ownership and control of various financial institutions. This article outlines a political economic framework for explaining and interpreting the significance of this proliferation of institutional investments into rural lands. Focusing on two of the nation's most important rural land resources—timberland and farmland—I suggest that we are witnessing an unprecedented integration between finance capital and landownership that harkens back to previous eras of rentier control. I further suggest that this increasing tendency to treat land as a financial asset—what I refer to as the “financialization of landownership”—gives rise to a number of contradictions that may have profound effects on rural communities across the United States. I conclude with a discussion of a land bubble and the role of institutional landowners in pushing up land prices in both timberland and farmland markets.  相似文献
