Abstract

Today's college students occupy a “window” between older adults, whose need for hepatitis B vaccination is minimal, and younger people who receive the vaccine as part of their childhood immunization series. However, because of the high-risk activities that are often part of student behavior, college students are among the individuals who are at the highest risk for this disease; 75% of all reported hepatitis B cases occur in persons between the ages of 15 and 39 years. It is therefore imperative that college health professionals take seriously their responsibility to educate students about issues related to hepatitis B and make available programs that enable the students to receive immunizations. This article briefly describes a successful hepatitis B education and immunization program at an institution that has no mandatory prematriculation immunization requirements.  相似文献

Intimate partner violence (IPV) damages a woman's physical and mental well-being, and indicates that her children are likely to experience abuse, neglect and other traumatic experiences. Adult HMO members completed a questionnaire about adverse childhood experiences (ACEs) including childhood abuse, neglect, and household dysfunction. We used their responses to retrospectively assess the relationship between witnessing intimate partner violence and experiencing any of the 9 ACEs and multiple ACEs (ACE score). Compared to persons who grew up with no domestic violence, the adjusted odds ratio for any individual ACE was approximately two to six times higher if IPV occurred (p < 0.05). There was a powerful graded increase in the prevalence of every category of ACE as the frequency of witnessing IPV increased. In addition, the total number of ACEs was increased dramatically for persons who had witnessed IPV during childhood. There was a positive graded risk for self-reported alcoholism, illicit drug use, i.v. drug use and depressed affect as the frequency of witnessing IPV increased. Identification of victims of IPV must include screening of their children for abuse, neglect and other types of adverse exposures, as well as recognition that substance abuse and depressed affect are likely consequences of witnessing IPV. Finally, this data strongly suggest that future studies, which focus on the effect of witnessing IPV on long-term health outcomes, may need to take into consideration the co-occurrence of multiple ACEs, which can also affect these outcomes.  相似文献

We discuss the privatization schemes of Chile and Argentina following a review of three alternatives to privatization. Our major conclusions are as follows: (1) the Chilean scheme has performed very well during much of the past 15 years, but it is not yet clear what will happen during an extended period of economic stagnation and declining financial markets; (2) for many countries it would make more sense to reform existing public pension schemes than to replace them with privatized schemes, at least until one has a better idea how privatized schemes perform in adverse financial environments; (3) privatized schemes have important distributional effects that deserve more attention.  相似文献

This article discusses the generational equity debate in the United States--including its origins and the functions it serves. This debate has emerged in the context of concerns over the aging of the population, budgetary crises, growing health care costs, increased poverty among children, growing economic inequality, and declining faith in institutions. By potentially fragmenting support for Social Security and other social programs, the generational equity approach to framing public policy issues may serve the interests of those conservatives wishing to shrink and restructure the American approach to social welfare. However, the possibility exists that this debate could serve also as a forum to advance progressive ideas about universal access for persons of all ages to income and health benefits and employment opportunities.  相似文献

Recent evidence from the U.S. and from other selected countries is examined on parent sex preferences for their children and how strongly these are held. This involves the significance of these preferences, the social and economic conditions that foster different types of preferences, and how different individuals and societies deal with them. The traditional preference for boys appears to remain nearly universal, which runs contrary to the ideal of "every child a wanted child," and also presents an obstacle to desired declines in fertility in developing countries where sons are still perceived as needed for economic and emotional security. This tendency has been turned around in Japan, Singapore, Hong Kong, and the U.S., where small families are now the ideal. 3 basic approaches to the scientific selection of sex-specific sperm for preselection, the timing of sexual intercourse, the separation of male- and female-bearing sperm followed by artificial insemination, and selective abortion after fetal sex determination indicate that an effective and practical method of sex control is still further off than predicted.  相似文献

Although public meetings are the most frequently used method for obtaining citizen input into public decision-making, there is little systematic evidence comparing attendees with citizens at large. This paper addresses this gap in the literature by analyzing results from a series of public meetings and a random-sample telephone survey. The public meetings and telephone survey were conducted in Hillsborough County, Florida to obtain citizen input for the purpose of establishing spending priorities for more than $39 million in federal block grant funds. Findings include representation at public meetings on a number of factors, including race, Hispanic ethnicity, and low-income status. Attendees favor redistributive activities more often than citizens at large; however, both attendees and the general public agree on the importance of funding activities serving certain vulnerable populations, including seniors, persons with disabilities, and victims of domestic violence.  相似文献

Since 1981 close to forty countries have introduced systemic pension reforms that have replaced all or part of prior pay‐as‐you‐go (PAYG) schemes with privately managed funded defined contribution (FDC) pillars or systems. However, over the past decade about half of these countries have subsequently cutback on, or entirely eliminated, these FDC schemes. In this article we explore some of the reasons why this reversal is often taking place in developing countries. As part of our analysis we propose a new pension reform typology that goes beyond the commonly used dichotomy between PAYG and pension privatization. We identify and discuss four factors that are of particular relevance to those seeking to understand the pension policy reversals that have been taking place in many developing countries: low pension coverage and incentive incompatibility, triple burden costs, tradeoffs between pension reforms and social pensions, and difficulties with annuitization.  相似文献
