Increasingly, health organisations and governing bodies in developed countries are paying serious attention to the problem of adult inactivity. Many of the programs designed to increase levels of activity, particularly amongst target populations, such as women, have not been systematically assessed for their effectiveness in recruiting women and helping them maintain activity levels. The purpose of this study was to determine what attracted and sustained women to participate in physical activity programs. Responses from a survey to sport and recreation program providers identified 64 successful programs in the state of Victoria, Australia. Eight of these programs were purposively selected for case study analysis. Data was collected from a focus group with women participants from each of these eight programs. Six core themes emerged from inductive content analysis of the focus groups. The most frequent participant responses related to the social aspects of the exercise environment. Women in the focus groups valued instructor professionalism and instructors’ technical knowledge, however, it was their awareness and sensitivity that participants appreciated most. This exploratory study is important because it reflects the voices of women talking about what made physical activity programs successful for them. The study raises critical questions that should be examined systematically through large-scale survey research and field-based intervention studies, which in turn should stimulate program development to encourage women in physical activity.  相似文献

Collaborative information seeking often takes place in co-located settings; such opportunities may be planned (business colleagues meeting in a conference room or students working together in a library) or spontaneous (family members gathered in their living room or friends meeting at a café). Surface computing technologies (i.e., interactive tabletops) hold great potential for enhancing collaborative information seeking activities. Such devices provide engaging direct manipulation interactions, facilitate awareness of collaborators’ activities, and afford spatial organization of content. However, current tabletop technologies also present several challenges that creators of collaborative information seeking system must account for in their designs. In this article, we explore the design space for collaborative search systems on interactive tabletops, discussing the benefits and challenges of creating search applications for these devices. We discuss how features of our tabletop search prototypes TeamSearch, FourBySix Search, Cambiera, and WeSearch, illustrate different aspects of this design space.  相似文献

Youth exposed to disasters experience stress and adjustment difficulties, which likely influence their interactions with peers. In this study, we examined changes in bullying and peer victimization in two cohorts of children. Youth from an area affected by Hurricane Katrina were assessed pre‐ and postdisaster (n = 96, mean [M] = 10.9 years old, 53% female), and a comparison group from a nearby area was assessed over the same time interval 1 year prior (n = 120, M = 10.2 years old, 52% female). Within the hurricane group, relations between symptoms of post‐traumatic stress disorder (PTSD) with bullying and victimization also were examined. Following the hurricane, the hurricane group reported increased relational and overt bullying relative to the nonhurricane group, and PTSD symptoms predicted increased victimization. Thus, school personnel should be vigilant and prepared to respond to increased bullying following disasters and for increased victimization in youth experiencing PTSD symptoms. © 2009 Wiley Periodicals, Inc.  相似文献

Many theories of giftedness either explicitly or implicitly acknowledge the role of genetic influences; yet, empirical work has not been able to establish the impact that genes have specifically on gifted behavior. In contrast, a great deal of research has been targeted at understanding the etiology of individual differences in general and specific cognitive abilities across the entire range of ability and to a lesser extent, high cognitive ability. This paper attempts to outline what we know and what we don't know about the etiology of giftedness as operationally defined as high g. We review studies selected to represent a variety of approaches that each address a different question about genetics and giftedness. These studies include quantitative genetic research which estimate heritability, shared and nonshared family environment – at the high and low ends of intelligence – as well as the heritability of group differences for general cognitive ability and specific cognitive abilities. We discuss the molecular genetic methods and mechanisms contributing to cognitive ability and suggest how epigenetic factors may operate. Quantitative and molecular genetic studies that include endophenotypes representing intelligence at a level closer to the genotype, are also included. This last group of studies represent a relatively new area of work that builds on and extends the extensive groundwork established by classic quantitative genetic studies of behavior.  相似文献

Using data from the National Early Head Start (EHS) Research and Evaluation Project (N = 1851), the current study examined relations among cumulative family and social risk, assessed during infancy and the preschool years, and children's prekindergarten achievement, self-regulatory skills, and problematic social behavior, testing if these associations were mediated through two sets of family processes–responsive parenting practices and the provision of language stimulation and literacy practices. Structural equation modeling results highlight the significance of the timing of children's experience of risk in predicting school readiness competencies. Risk exposure during infancy was observed to be most detrimental for children's school readiness skills and was partially mediated by risk exposure during the preschool years and family processes, assessed during toddlerhood and the preschool years. Moderation analyses revealed no difference in the strength of relationships among the study variables by EHS assignment or by race/ethnicity.  相似文献

This study draws on student engagement factors to examine the relationship between students’ non-school-based arts experiences on their intrinsic motivation and self-efficacy to participate in visual arts responding tasks. Visual arts responding in the curriculum includes learning about artists and artworks, decoding art and making critical judgements, and is important in building twenty-first century learning skills such as critical thinking and communication. A total of 266 Year 10 to 12 students from 18 schools in Western Australia (WA) participated in the quantitative research, which explored outside-school arts engagement as well as cognitive and psychological engagement factors in their current year of secondary schooling. The findings showed that while being an art consumer appears to impact on intrinsic motivation and self-efficacy, producing art as a hobby outside of school does not appear to do so. The research raised questions about links between practice and theory, and how to promote students’ engagement in responding.  相似文献
