The vast majority of American middle schools and high schools sell what is known as "competitive foods", such as soft drinks, candy bars, and chips, to children. The relationship between consumption of sugar-sweetened drinks and snacks and childhood obesity is well established but it remains unknown whether competitive food sales in schools are related to unhealthy weight gain among children. We examined this association using data from the Early Childhood Longitudinal Study Kindergarten Cohort. Employing fixed effects models and a natural experimental approach, we found that children's weight gain between 5(th) and 8(th) grades was not associated with the introduction or the duration of exposure to competitive food sales in middle school. Also, the relationship between competitive foods and weight gain did not vary significantly by gender, race/ethnicity, or family SES, and remained weak and insignificant across several alternative model specifications. One possible explanation is that children's food preferences and dietary patterns are firmly established before adolescence. Also, middle school environments may dampen the effects of competitive food sales because they so highly structure children's time and eating opportunities. 相似文献

This preliminary study investigated the impact of the online interactive programme Brainology (which aimed to encourage a growth mindset) on the mindset, resiliency and sense of mastery of secondary school pupils. A quasi-experimental pre-, post- and follow-up mixed-methods study was carried out with 33 participants aged 13–14?years. The measures were Dweck’s theories of intelligence scale and Prince-Embury’s resiliency scales for children and adolescents. Quantitative data were analysed using analysis of variance. Qualitative data from focus groups were categorised and coded. The programme led to a significant increase in pre- to post-mindset scores for the intervention group. However, there was a significant decline at follow-up and the initial impact of the intervention was not sustained. There were no significant changes in mindset for the comparison group. There were no significant changes in resiliency or sense of mastery for either group. The significant short-term impact of Brainology and non-significant follow-up findings are discussed. The present study has limitations such as small sample size, which has implications for generalisability. Future research should investigate the longer term effectiveness of educational interventions in schools.This article has been corrected with minor changes. These changes do not impact the academic content of the article. 相似文献

This paper discusses the emerging paradigm of project management performed in a web-based working environment. It highlights how project management and its associated features are strongly linked to fulfilling quality and value criteria for customers, and it examines how collaborative working environments can greatly reduce the administrative burden of managing large projects, especially and almost paradoxically, when resources are limited. Specifically, the paper examines the application of a project management methodology (PRINCE2) together with the use of a collaborative web-based working environment over a number of pilot projects at Leeds University Library. It describes the pilot phase of a library management decision to run a series of major Library projects using project management methodology, while continuing to run other projects through the existing locally developed planning mechanisms and describes the pitfalls of these latter alternatives, less sophisticated project management tools, and describes the main issues that this change in practice has brought to light. It draws preliminary conclusions about the effectiveness of this change in practice in one of the UK's largest academic libraries. 相似文献

This study investigates the ideological implications of Nambowon (‘the Committee for Men's Rights’), one of the most popular sketches in a live comedy series entitled Gag Concert in Korea. The sketch humorously criticizes women who take advantage of men in various situations and always ends with a funny slogan demanding equal rights for men and the end of reverse gender discrimination. We treat Nambowon not as an idiosyncratic text but as part of Korean television programs that portray the rising social status of women as well as gender differences. Previous studies of gender and comedy have typically focused on textual meanings, and relatively little work exists to explain the audience's reception. Thus, we explore why audiences enjoy the show and whether and why there are differences in the reactions of male and female viewers to the portrayal of gender in Nambowon. 相似文献

Downward career changes are challenging in societies which place a premium on the accumulation of material wealth and discourage risk-taking, such as Singapore. To better understand how individuals manage their identities during such changes, 30 individuals who had completed a voluntary downward career change were interviewed. Results suggest three phases of communication during this process: (1) Decision making, in which individuals communicate to gather information about the change and seek support for it; (2) Announcement, in which they strategically time, frame, and deliver the message to maximize acceptance of the change; and (3) New career, in which they reframe, refocus, and recalibrate to increase their social identity. The findings suggest strategies individuals may use to effectively manage their social identities as they change careers and suggest strategies organizations may use for recruiting individuals into socially less-prestigious occupations. 相似文献

Young offenders have a high prevalence of mental illness and a large proportion report experiencing a number of traumatic events during childhood, but there is little research exploring this association. This study describes the prevalence of, and association between, child maltreatment and post-traumatic stress disorder (PTSD) among young offenders. The study uses data collected as part of the 2009 NSW Young People in Custody Health Survey which was conducted in nine juvenile detention centers. This paper reports on findings from the baseline questionnaires and 18-months of re-offending data. The analysis included 291 participants who were assessed for PTSD and child maltreatment. The sample was 88% male, 48% Aboriginal, with an average age of 17 years (range 13–21 years). One in five (20%) participants were diagnosed with PTSD, with females significantly more likely to have PTSD than males (40% vs. 17%, p < 0.05). Over half (60%) of young offenders reported any child abuse or neglect, with females nearly 10 times more likely to report three or more kinds of severe child maltreatment than males. The main correlate for a diagnosis of PTSD was having three or more kinds of severe child maltreatment (OR = 6.73, 95% CI: 1.06–42.92). This study provides evidence for the need to comprehensively assess child abuse and neglect among young offenders in order to provide appropriate treatment in custody and post-release. 相似文献

Beyond the Tipping Point: Issues of Racial Diversity in Magnet Schools Following Unitary Status 总被引:1,自引:1,他引:0

This article uses qualitative case study methodology to examine why the racial composition of magnet schools in Nashville, Tennessee, has shifted to predominantly African American in the aftermath of unitary status. The article compares the policy contexts and parents' reasons for choosing magnet schools at two points in time—under court order and under unitary status. Social networks, choice sets, and “closer to home” student assignment policies are identified as key influences on the changing demographics of magnet schools in a postunitary status environment. 相似文献

This paper reports the findings from a study of schools' responses to child bereavement in Hull, Yorkshire and Derry/Londonderry, Northern Ireland. In order to gain an insight and compare how schools in both geographical areas respond to and manage bereavement, the questionnaire ‘Loss in schools’ was selected as an appropriate tool. It has been utilised on previous occasions in Hull and shown to be an effective method of highlighting the issues, needs and concerns of schools. Some significant and important issues emerge in the results of the present survey. While schools rate child bereavement and parental separation highly in terms of their priorities, there is a shortfall in the number of schools in both study sites that have a formal procedure or policy in place around the management and response to death and loss. Although there is evidence that a number of staff have attended training in loss and bereavement, schools in Derry/Londonderry and Hull report that they have sought help from other agencies in times of need. For example, the Western Education and Library Board Bereavement Team and Cruse Bereavement Care (Derry/Londonderry) and the Educational Psychology Service (Hull) are identified. Schools are asking for help and support to develop policies and to gain the knowledge and skills they require to respond with confidence to a child who experiences a loss. 相似文献
