ABSTRACT We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults. 相似文献

Selective universities regularly employ policies that favor children of alumni (known as legacies) in undergraduate admissions. Since alumni from selective colleges and universities historically have been disproportionately white, admissions policies that favor legacies have disproportionately benefited white students. For this reason, legacy policies lead to additional costs in terms of reductions in racial diversity. As larger numbers of minority students graduate from colleges and universities and have children, however, the potential pool of legacy applicants will change markedly in racial composition. This analysis begins with a review of the history and objectives of the preference for children of alumni in undergraduate admissions. We then consider the specific case of the University of Virginia and employ demographic techniques to predict the racial composition of the pool of potential legacy applicants to the university. Significant changes in the racial composition of classes that graduated from the University of Virginia from the late 1960s through the 1970s foreshadow similar changes in the characteristics of alumni children maturing through the next two decades. 相似文献

The present study compared Chinese and Canadian children's moral evaluations of lie and truth telling in situations involving pro- and antisocial behaviors. Seven-, 9-, and 11-year-old Chinese and canadian children were presented 4 brief stories. Two stories involved a child who intentionally carried out a good deed, and the other2 stories involved a child who intentionally carried out a bad deed. When story characters were questioned by a teacher as to who had committed the deed, they either lied or told the truth. Children were asked to evaluate the story characters' deeds and their verbal statements. Overall, Chinese children rated truth telling less positively and lie telling more positively in prosocial settings than Canadian children, indicating that the emphasis on self-effacement and modesty in Chinese culture overrides Chinese children's evaluations of lying in some situations. Both Chinese and canadian children rated trugh telling positively and lie telling negatively in antisocial situations, reflecting the emphasis in both cultures on the distinction between misdeed and truth/lie telling. The findings of the present study suggest that, in the realm of lying and truth telling, a close relation between sociocultural practices and moral judgment exists. Specific social and cultural norms have an impact on children's developing moral judgments, which in turn, are modified by age and experience in a particular culture. 相似文献

Information and communication technologies (ICTs) represent a crucial force for cultural change in both education and society and possible transitions between old and new learning as well as social values. This is especially so in East Asia, where the young have informally embraced ICTs but learn in formal contexts often still dominated by traditional transmission models of learning rather than the new learner‐centred theories which inform policy imperatives for innovation and reform. Educational contexts like Singapore and Hong Kong are particularly exemplary because they have been so progressive in policy initiatives for ICT integration and reform in formal education, imperatives which conflict in practice with still dominant traditional learning expectations, teaching practices and models of assessment. As typified by such contexts, this paper investigates how the pedagogical dilemmas of a tension between old and new models of learning need to be understood and approached in terms of related and overlapping institutional and social dilemmas of change. 相似文献

The relationship of past and present and the linking of characters through time and place are themes that underlie the work of many writers for children. This article considers the use of the Ghost as a literary device to allow the exploration of what is, what has been, and what might have been, particularly in the 1973 Carnegie Medal Winner,The Ghost of Thomas Kempe, by Penelope Lively.Judith Armstrong was brought up in Lancashire. She has travelled widely, and taught young children in England and Ethiopia. She is currently working on themes associated with the supernatural in children's books. 相似文献

Initial intervention processes for children with intellectual disabilities (IDs) largely focused on direct efforts to impact core cognitive and academic deficits associated with the diagnosis. Recent research on risk processes in families of children with ID, however, has influenced new developmental system approaches to early intervention. Recent risk and resilience processes are reviewed that connect stress, family process, and the high rates of behavioral problems in children with ID that have substantial influence on child and family outcomes. These models are linked to emerging evidence‐based intervention processes that focus on strategic parent skill training and mindfulness interventions that reduce parental stress and create indirect benefits for children's behavioral competencies. A family‐focused developmental systems approach (M. J. Guralnick, 2011) is emphasized. 相似文献
