This study examines demographic and situational factors in an effort to predict whether or not a complainant was injured, used resistance, experienced a completed assault, and whether charges were brought against the offender. If the accused had consumed alcohol or drugs, he was almost seven times more likely to be arrested. The complainant was six times more likely to report rape completion if she had consumed alcohol or drugs and if the complainant fell unconscious at any time during the attack she was significantly less likely to use a resistance strategy. The complainant's use of a compliance strategy at any time during the assault positively predicted not using a physical resistance strategy and sexual assault completion. The reporting of injury positively predicted use a physical resistance strategy and sexual assault completion. If the assault was completed, it was less likely that charges were pressed. Implications of these findings are discussed, and directions for future research are offered.  相似文献

Clients with psychotic disorders are at great risk for relapse and rehospitalization. This risk is magnified by poor adherence to medications, as well as refusal to accept optimal treatment planning, including more beneficial atypical medications. Adherence can be even more compromised because of clients' poor insight into these illnesses and their inability to recognize the potential for recovery that exists when taking medications as prescribed. This poor insight makes effective collaboration in treatment more difficult and is an exceptionally troubling impediment to successful treatment. Currently, there are few effective strategies to improve insight into psychosis. We have developed the Levels of Recovery from Psychotic Disorders Scale (LORS) as a teaching tool. It is designed to identify strengths and weaknesses in insight in order to provide the basis for an intervention to enhance and promote change. This article reviews the relevant literature on adherence and insight in this population of clients with psychotic disorders. It also reviews a pilot study comparing the LORS to the BASIS-32. The findings provide the basis for future studies using the LORS to enhance insight, adherence, and recovery.  相似文献

Whole-genome sequences are now available, and methods have evolved for targeting, in parallel, each gene in a genome, offering for the first time the opportunity to study the entire dynamic network of genes involved in aging. At a recent conference in Hersonissos, Crete, around 200 internationally renowned experts gathered to discuss techniques and emerging results as the science of aging undergoes a shift toward systems biology.  相似文献

Where strength training has been used in conjunction with functional-task training in older people, not only have there been improvements in leg strength but also improved function has been measured (e.g., Skelton & McLaughlin, 1996). Many studies use participants from care homes rather than community dwellers. We investigated changes in leg power, balance, and functional mobility in community-dwelling sedentary men and women over 70 years of age (n = 6 for training group [TR]; n = 10 for control group [CN]). Progressive training took place over 24 weeks using seated and nonseated exercise. For TR, leg power increased 40%, from 108 +/- 40 to 141 +/- 53 W (p < .01); dynamic balance increased 48%, from 22.3 +/- 7.9 to 33.1 +/- 6.1 cm (p < .01; functional reach); and functional mobility increased 12%, from 7.46 +/- 1.32 to 6.54 +/- 1.41 s (p < .05; timed walk). CN showed no significant change. In conclusion, a community-based exercise program led to large improvements in leg-extensor power, dynamic balance, and functional mobility.  相似文献

Numerous methods for studying the prevention of falls and age-related sensorimotor degradation have been proposed and tested. Some approaches are too impractical to use with seniors or too expensive for practitioners. Practitioners desire a simple, reliable technique. The goals of this research were to develop such an approach and to apply it in exploring the effect of Tai Chi on age-related sensorimotor degradation. The method employed artificial-neural-network (ANN) models trained by using individuals' center-of-pressure (COP) measurements and age. Ninety-six White and Chinese adults without Tai Chi training were tested. In contrast, a third group, Chinese seniors with Tai Chi training, was tested to ascertain any influence from Tai Chi on sensorimotor aging. This study supported ANN technology with COP data as a feasible tool in the exploration of sensorimotor degradation and demonstrated that Tai Chi slowed down the effects of sensorimotor aging.  相似文献

Work in construction is associated with a high risk for musculoskeletal disorders and injuries. The symptom survey was conducted to determine the magnitude and musculoskeletal injury characteristics among the cement and concrete workers and identify the most problematic work-related activities and job factors that might have contributed to the occurrence of these disorders. Findings revealed that a large proportion of the laborers (77%) experienced at least one musculoskeletal disorder in the last year. Low back pain was reported as the most frequently experienced symptom (66%). 'Working while in pain' the concrete workers perceived as the major problem in the trade. Other problematic work-related activities included 'bending or twisting the back', 'work in hot, cold or wet conditions', and 'handling heavy objects'. Most of the laborers (82%) requested on-the-job safety training. Survey results combined with the outcomes of focus groups discussions and work site observations were used in the design of a training program aimed at the prevention of musculoskeletal morbidity in the trade. The program incorporated ergonomics principles, hazard recognition, safe work practices, problem solving and personal protection in the training curriculum for membership of the trade.  相似文献

Body mechanic checklist scores during a one-person pivot transfer, and boosting up in bed were evaluated to determine the effectiveness of training on the work performance of female student nurses from a local college. Thirty subjects participated in the study and were divided into a control group, an experimental group that received basic body mechanic training, and an experimental group that received job specific training. A one-way ANCOVA was calculated to examine the effects of the experimental procedures on the subjects' performance. This revealed a statistically significant difference between the groups (patient transfer F = 10.11, p value < 0.001; boosting F = 38.62, p value < 0.001). A post hoc analysis (Bonferroni procedure) indicated that the job specific training group (mean 11.65, SD 0.66) demonstrated a statistically significant improvement in their performance compared to the other two groups (control group mean 7.5, SD 0.67; BBMT mean 9.66, SD 0.67).  相似文献
