STAFF AND ELDERLY KNOWLEDGE AND ATTITUDES TOWARD ELDERLY SEXUALITY     

Bonnie L. Walker  Nancy J. Osgood  James P. Richardson  Paul H. Ephross 《Educational gerontology》2013,39(5):471-489

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

How home gets to school: Parental control strategies predict children's school readiness     

Aimée Kleisner Walker David MacPhee 《Early childhood research quarterly》2011,26(3):355

At-risk families’ control style (autonomy support and coercive control) was examined in relation to children's school readiness; children's social skills and mastery motivation were hypothesized mediating variables. In two different, low-income samples from diverse ethnic backgrounds, one preschool sample recruited from Head Start (N = 199) and a school transition sample composed of children entering elementary school (N = 344), parental control styles were related to children's academic readiness modestly but significantly in the preschool sample and weakly in the school transition sample. Children's social skills and mastery motivation skills (persistence and goal orientation) were significantly related to the academic measures of school readiness, and fully mediated the association between parents’ use of coercive behavioral control and academic readiness. Such mediation could not be tested for parental support of children's autonomy. The results indicate that a developmental cascade exists between parental control strategies and academic indices of school readiness, emphasizing the importance of family context models of school readiness. Furthermore, strong correlations between the domains of school readiness were found in both samples, reinforcing calls for a multidimensional approach to supporting school readiness in early childhood education programs.  相似文献   

Three‐year results of the Friendly Schools whole‐of‐school intervention on children's bullying behaviour

A group randomized controlled trial tested the efficacy of the Friendly Schools program to reduce student bullying behaviour. This socio‐ecological intervention targeted the whole school, classroom, family, and individual students to reduce bullying behaviour. Self‐report data were collected in 29 schools over three years from a cohort of 1968 eight to nine‐year‐olds. Surveys measured frequency of being bullied, bullying others, telling if bullied and observing bullying. Results indicate that intervention students were significantly less likely to observe bullying at 12, 24 and 36 months and be bullied after 12 and 36 months, and significantly more likely to tell if bullied after 12 months than comparison students. No differences were found for self‐reported perpetration of bullying. The findings suggest whole‐of‐school programs that engage students in their different social contexts appear to reduce their experiences of being bullied and increase their likelihood of telling someone if they are bullied.  相似文献   

Corresponding drivability control and energy control strategy in uninterrupted multi-speed mining trucks     

Weiwei Yang  Jiejunyi Liang  Jue Yang  Paul D. Walker  Nong Zhang 《Journal of The Franklin Institute》2021,358(2):1214-1239

An hybrid uninterrupted multi-speed transmission (HUMST), based on the integration of a planetary gear set and a 3-speed automatic manual transmission (3-AMT), is developed to satisfy the specific performance indexes of mining trucks. The power-split device can alleviate and eliminate the inherent torque interruption of the 3-AMT during gear shift by implementing the designed cooperative shift control strategy which is optimized by quadratic performance index. In order to achieve fast torque coordination while guaranteeing the driving comfort performance, the torque profiles of the power split device and the traction motor are optimized by Linear-quadratic regulator (LQR) algorithm. Dynamic programming (DP) is implemented as a benchmark to demonstrate the maximum fuel efficiency of the proposed HUMST. Because of the high computational cost of optimal control strategies such as DP, an improved real-time control strategy (IRTCS) using modified Gaussian distribution function is proposed to significantly reduce the computing load. As efficiency-oriented energy control strategy would result in frequent gear shifts, to achieve a desirable tradeoff between the overall efficiency and the shift stability, multi-objective genetic algorithm (MGA) is integrated to optimize the overall performance. The detail mathematical and dynamic model shows that the proposed shifting strategy with LQR can effectively suppress shift jerk, and the proposed IRTCS with MGA can reduce shift frequency by 70.78% to improve the drivability, only sacrificing 4.86% of overall efficiency compared to that of DP.  相似文献
