This study investigated the effect of a 12-week pedometer-based intervention on daily step counts of 147 older adults randomly assigned to an intervention or wait-list control group (M age = 72.9 years, SD = 8.8). The intervention group significantly increased their daily step counts after 12 weeks (M=639, SD=2239) and continued to significantly increase during a 12-week maintenance period (M=680, SD=1721). The control group exhibited no change during the control period (M = -393, SD=2050) but had a significant increase in daily step counts (M=1580, SD=2305) when enrolled in the intervention. The pedometer-based intervention was effective in increasing participants' daily step counts.  相似文献

To implement restorative care in assisted living facilities, staff need to understand the philosophy and learn methods to help residents maintain optimal function. In this study, the researchers developed a multimedia training program designed to teach staff how to encourage residents to increase their participation in dressing themselves. Researchers conducted a pilot test to measure the short-term effects of the training on 40 staff from two states. Program effects were measured by completing a survey developed by the researchers. Pretest scores were significantly related to gender (women as a group had higher scores than men). Results indicated significant gains in knowledge at posttest. In addition, 93% of participants described positive changes related to restorative care that they planned to make at their facility as a result of the training.  相似文献

This paper reports the conclusions and recommendations of the working group that synthesized the discussions on ‘How can science connect with and be of greater benefit to conservation practice?’ during the ICCROM Forum on Conservation Science. The author reflects on these findings from her own perspective and experiences, and places them in the context of two major shifts in heritage research: the first, a shift in focus from conserving materials to managing meaning. The second, a shift in organizational structures from single, centrally funded heritage institutions towards diffuse networks which include new players who have no direct responsibility towards heritage. Both shifts are taking place in an environment of decreased funding and increased accountability to society. Science and conservation connect and contribute to each other most effectively if they together contribute to the societal benefits of heritage. In this regard, heritage science strategies can stimulate collaboration, and direct science and conservation towards innovative, applicable outcomes. Moreover, they can promote a transdisciplinary approach which connects social, economic and business sciences and stakeholders. They should also ensure the creation of sustainable nodes for consolidating knowledge within these dynamic networks.  相似文献

We describe a microfluidic device for on-chip chemical processing, such as staining, and subsequent washing of cells. The paper introduces “separator walls” to increase the on-chip incubation time and to improve the quality of washing. Cells of interest are concentrated into a treatment stream of chemical reagents at the first separator wall for extended on-chip incubation without causing excess contamination at the output due to diffusion of the unreacted treatment chemicals, and then are directed to the washing stream before final collections. The second separator wall further reduces the output contamination from diffusion to the washing stream. With this approach, we demonstrate on-chip leukocyte staining with Rhodamine 6G and washing. The results suggest that other conventional biological and analytical processes could be replaced by the proposed device.  相似文献

This study compared staff and elderly knowledge, attitudes, and practices related to sexual expression by elderly persons in a long‐term care setting. Volunteers (N = 194) responded agree or disagree to 159 items. Significant differences were observed between the staff and elderly responses on 36 items. Areas of greatest differences involved knowledge and attitudes about consensual sex and sexual abuse, issues related to family attitudes toward remarriage and sexual expression, and age‐related changes and health problems related to sexuality. Items related to masturbation received the greatest percentage of no response. The staff had significantly higher total scores as compared to the elderly reflecting more knowledge, positive attitudes, and support for more proactive responses toward elderly sexuality. Findings have major implications for staff training in long‐term care settings.  相似文献
