Childless Elders in Assisted Living: Findings from the Maryland Assisted Living Study

We compared data drawn from a random sample of 399 current assisted living residents and a subsample of 222 newly admitted residents for two groups: childless residents and residents with children. The percentage of childless residents (26%) in our study was slightly higher than U.S. population estimates of childless individuals aged 65 years and older (20%). In the overall sample, the two groups differed significantly by age, race, and women's years of education. The childless group was slightly younger, had a higher percentage of African American residents, and had more years of education than the group with children. In the subsample, we looked at demographic, functional, financial, and social characteristics and found that childless residents reported fewer diagnoses of dementia and fewer visits from a relative but more reported paying less money per month for assisted living and having private insurance than residents with children. As childlessness among older adults continues to increase, it will become increasingly important to understand how child status affects the need for and experience of long-term care.     

谈谈学分制下如何做好学生党建工作

全面推行学分制是高校教学改革的深化,是教育和教学改革的一个发展阶段.但由于学分制所带来的思想教育、学生党建等新情况、新问题,应值得所有教育者认真思考和研究的.本文围绕学分制实行后给学生党建工作带来的"四难"以及如何应对提出了一些理论和实践的思考.     

Has the rise in globalization reduced U.S. inflation in the 1990s?

This article investigates whether increased globalization of the U.S. economy has helped hold down inflation in the 1990s. Based on several measures, we find that globalization has increased. Further, we find that import prices exert a greater impact on prices of products in industries faced with greater import penetration. High foreign excess capacity accounts for much of the recent decline in U.S. inflation. Our results suggest that the decline in inflation is explained by the interaction of increased globalization and high excess foreign capacity. Globalization by itself does not lead to less inflation, just greater sensitivity to foreign economic conditions.     

Language Games and Natural Reactions

Ludwig Wittgenstein imagines a variety of eccentric social practices—like a tribe trained "to give no expression of feeling of any kind". But he also speaks of "the common behavior of mankind" that is rooted in "natural/primitive reactions". This emphasis on the uniformities of human behavior raises questions about the plausibility of some of his imagined language games. Indeed, it suggests the claim of evolutionary psychologists that there are biologically based human universals that shape social practices. But in contrast to E.O. Wilson's belief that "genes hold culture on a leash", Wittgenstein sees culture as a mediator—rather than a conduit—of "natural reactions". This suggests that social science can incorporate the claims of evolutionary psychology without scanting the centrality of culture in action and allows that nature can be overwhelmed by culture.     

Experiences of Sleep and Benzodiazepine Use among Older Women

Sleep disturbances are common among older women; however, little is known about sleep experiences among chronic benzodiazepine users. The experience of sleep, sleep troubles, and management of sleep problems were explored through semistructured interviews with 12 women aged 65–92 who had used a benzodiazepine for three months or longer to treat a sleep disturbance. Themes that emerged from an interpretive phenomenological analysis included multiple reasons for sleep disruptions (health problems, mental disturbances, and sleeping arrangements), opposing effects of benzodiazepines on sleep (helps or does not work), and several supplemental sleep strategies (modification of the environment, distraction, and consumption).     

蒙古国的民族问题与民族政策

蒙古国的民族构成以蒙古族为主,占总人口的90％以上,蒙古族内的十几个部族虽然在方言、风俗习惯和服饰上有所差别,但能自由交流。哈萨克、乌梁海、图瓦、霍屯等突厥民族只占6％多一点。蒙古国民族问题的主要表现是哈萨克族的迁徙问题。在1991-1992年间就有4.1万人迁居到哈萨克斯坦国。迁徙的主要原因：一是蒙古国历届政府对民族理论和民族宗教政策的研究落实不得力;二是受国际大气候的影响,泛民族主义意识抬头。针对这种情况,蒙古国政府采取了协商解决一切问题的方针,及时出台了一些政策法规,收到了较好的成效。     

A Time‐Dependent Risk Assessment for Broken Compact Fluorescent Lamps

Environmental Protection Agency (EPA) ambient air quality guidelines are meant to limit long‐term exposures of toxins to safe levels. Unfortunately, there is little guidance for what constitutes a safe level from a one‐time (or very infrequent) short exposure(s). In the case of mercury, a review of the derivation of the EPA ambient air quality standard shows that it implicitly assumes a tissue burden model. The time dependence of the tissue burden is commonly described in terms of a half‐life, a modeling assumption that presumes that the decline in the tissue burden after a single exposure can be approximately described as an exponential decay. In this article, we use a simple exponential tissue burden model to derive a time‐dependent no observable adverse effect level (NOAEL) for mercury concentrations in air. The model predicts that tissue body burden will asymptotically approach the EPA air quality level for long exposure times, and reach workplace standard levels for exposures of a few hours. The model was used along with data on mercury levels from experimental work done by the Maine Department of Environmental Protection to evaluate the risks from a broken compact fluorescent lamp in a residential setting. Mercury levels approached the NOAEL only when the debris was left in an almost sealed room. Normal common‐sense cleaning measures: removal of debris to an outside area, and ventilation of the room for several minutes, reduced exposures to less than 1% of the NOAEL.     

Beyond PowerPoint™: Using Learning Objects to Enhance Social Work Courses

Faculty use of information and communication technologies (ICT) in social work courses has the potential to transform social work education, including increasing student engagement and accommodating different learning styles. Learning objects are reusable digital resources with a pedagogical purpose that may be used in online, hybrid, or face-to-face social work courses to achieve these and other pedagogical benefits. This article defines and provides an overview of the concept “learning objects.” Guidelines for locating and incorporating existing learning objects and for creating learning objects for use in social work courses are detailed. Finally, examples are provided.
