The aging of the Baby Boom presents long-term care with many new challenges. Among these are the historically high levels of drug use by this cohort. This study surveyed administrators of licensed skilled nursing facilities in the Commonwealth of Kentucky regarding their perception of current drug use by residents, facility policies and procedures currently in place regarding illicit drug use, and their attitudes toward use of illicit drugs by residents. The results of interviews with 40 administrators or their designees revealed that they have experienced little problem with use or abuse of illegal drugs by residents. Fewer than one-third of the facilities had formal policies in place regarding illegal drug use. Only 10% had any experience with requests for medical marijuana, but almost one in five had a policy on the matter and nearly one-third stated they would support medical marijuana use by some of their residents if the matter arose. These authors recommend the following: (a) that the issue of illicit drug use needs to be addressed now before the situation becomes critical, (b) that administrators and staff need to be educated about recreational drug use and appropriate responses to drug abuse, (c) that screening instruments for drug abuse in this population should be developed and implemented, and (d) that policies regarding medical marijuana need to be adopted by all such facilities.  相似文献

Physical inactivity (and unhealthy nutrition) has distorted body composition and, in turn, reordered the proportions of myocyte and adipocyte insulin receptors. Insulin acting on adipocyte receptors produces less glucose uptake than does comparable interaction with myocyte receptors. Accordingly, in individuals with disproportionate muscle/fat composition, any given glucose load requires greater-than-normal pancreatic insulin secretion for adequate disposal. This hyperinsulinemia then becomes the leading cause of type 2 diabetes (T2DM) as insulin-sensitive tissues become desensitized. Because T2DM is rooted in potentially reversible lifestyle factors, rather than focusing on the intricacies of glucoregulation at the molecular level and on testing new drugs to control blood sugar, this article calls for a new prevention and treatment paradigm, in which exercise and weight control are essential and for which an inexpensive and acceptably accurate measure of body muscle and fat proportions is needed.  相似文献

In the continuing concern about academic standards in the higher education sector a great deal of emphasis has been placed on quality assurance procedures rather than on considering how university tutors learn to grade the quality of work produced by students. As part of a larger research project focused on how tutors grade student coursework, this paper offers a new metaphor for such tutor learning, based on a sociocultural perspective. The research project used think‐aloud protocols recorded as university tutors graded student coursework, and this was followed by semi‐structured interviews. The voluntary participants consisted of 25 lecturers in four contrasting domains—humanities, art and design, medicine and teacher education—in three universities, two teaching‐led and one research intensive. We developed a metaphorical framework that helps to understand the work and learning of the lecturers and tested it by applying it to analysis of the tutor interview data. Grading, writing feedback, second marking and moderation are important situated professional learning opportunities for tutors to debate and reach agreement on the academic standard demonstrated by student coursework. The metaphor considers professional learning as interplay between the vertical domain of public knowledge and the horizontal domain of teachers' practical wisdom. The metaphor presented in this paper is proposed for critical consideration and wider use by academics, teachers, academic developers and teacher educators as an aid to better understanding of teacher's professional learning.  相似文献

Assessment is often treated as an unwelcome and time-consuming university or departmental requirement. This project proposes that assessment is actually an opportunity that communication faculty should embrace. Beginning with the end in mind, this study used stated course learning outcomes to construct a pre-/posttest instrument, administering those assessments in order to find out whether students were really learning what they were supposed to be learning. This article explains how the assessment instruments were constructed and administered, demonstrates clear and significant learning gains across three semesters, and identifies learning outcomes in need of instructional improvement. It also finds that by separating assessment from grading, pretests can identify concepts that need not be retaught, and posttests can reveal that an instructor’s perception of a successful instructional day does not necessarily match the reality of student learning for that day.  相似文献

Much is known about the negative consequences of exposure to ethnic/racial stereotypes in the media, on White audiences. However, there is substantially less research addressing the effects of such media content on members of racial/ethnic minority groups. The present study examines this question using repeated cross-sectional national level data alongside a content analysis of top prime time shows between 1987 and 2008. Multi-level modeling analyses reveal that media representations of Latinos and Blacks were associated with Latinos’ and Blacks’ ingroup attitudes, however effects on attitudes towards Whites were not significant.  相似文献

In three experiments, we examined humans’ folk physics (i.e., a naturally occurring and spontaneous understanding of the physical world), using variations of problems used to study chimpanzees’ folk physics. Presented with trap-tube problems in two experiments, adult humans showed an unnecessary bias to insert a stick into the end of the tube farthest from the reward to push it out the other end. When presented with trap-table problems with ineffective trapping holes, people unnecessarily avoided the side with the hole. The similarity of humans’ and chimpanzees’ behavior on these tasks highlights methodological and conceptual problems in studies of chimpanzees’ folk physics and suggests alternative explanations for their behavior.  相似文献

While working together on tradition-based and contemporary works at the Smithsonian's National Museum of African Art (NMAfA) and in private practice, the authors found that their expertise in ethnographic conservation can be applied to the conservation of contemporary works. The treatment approach to ethnographic works has evolved over decades, shifting from alteration of original surfaces and heavy restoration to an emphasis on preserving the original integrity of the artwork through minimal intervention. This paper describes the evolution of ethnographic object conservation regarding surface alteration, while specifically focusing on African objects, and discusses applications of this approach to the conservation of contemporary art. The historical change in treatment attitudes is presented using examples from NMAfA's collections to underscore why the profession developed a minimal intervention approach and to argue for the relevance of this approach to related contemporary media.  相似文献

Background: Previous studies of mastery motivational climates within physical education have reported that providing students with opportunities to become self-directed leads to a number of positive outcomes, including skill attainment and increased perceptions of ability. Nonetheless, within all of these studies, there has been no account of the teaching/learning process or the behaviour of the students and teachers within the various interventions.

Purpose: The purpose of this study was to provide a micro-analysis of life in a mastery climate which was grounded in the classroom ecology paradigm.

Participants and setting: The participants in this study were 13 children (11 boys and 2 girls) all aged 4 years at the commencement of the programme. The children were attendees at a day-care centre that serves mostly African-American children from the local community who are environmentally at risk for developmental delay and poor health. The teacher in this study was a faculty member at the university where the programme took place. For 30 minutes each Tuesday and Thursday, the children participated in a programme of motor skill instruction that was based upon the key principles of a mastery-motivational climate. Selected station activities were designed to promote the acquisition of locomotor and object control skills.

Methods: A mixed-methods approach was taken, with data sources including interviews with the teacher, and an analysis of the ecology of the gymnasium using a modified version of the task structure system. Focus was placed upon the task goals, the teacher's accountability strategies, as well as task accomplishment in both the managerial and instructional task systems.

Findings: The key finding from this study was an appreciation of how time is a significant factor in the ways in which children initially responded to and eventually embraced the freedoms afforded to them in a mastery climate. Of particular note, the results show substantial differences in the children's lesson engagement not only across time, but also within lessons themselves. It is hypothesized that as they progressed through the programme, the children not only were more able to identify the demands of the task but were also able to filter out extraneous signals that might promote off-task or inappropriate behaviour.

Conclusions: The design of this study reinforced the value of adopting an ecological analysis of life in a mastery climate. Further, the results of the study showed the value of examining young children's engagement over a lengthy intervention. While such climates are expected to have lower levels of engagement and higher levels of off-task behaviour than more teacher-directed formats, by the end of the study the children were able to achieve levels of appropriate task engagement above 80% of lesson time.  相似文献
