Objective: To help clarify the effect of gender on the bidirectional relationship between alcohol use and strenuous physical activity in college students. Participants: Five hundred twenty-four (52% female) college students recruited in August 2008 and 2009 and followed up in April 2009 and April 2011, respectively. Methods: Participants reported their alcohol use and strenuous physical activity on 2 occasions (baseline and follow-up) spaced approximately 1 or 2 years apart. Results: For females, alcohol use quantity at baseline was associated with increased strenuous physical activity at 1- and 2-year follow-ups, and alcohol use frequency at baseline was associated with decreased strenuous physical activity at 2-year follow-up. For males, alcohol use frequency at baseline predicted decreased strenuous physical activity at 1-year follow-up. Conclusions: Gender differences may be explained from an eating disorders perspective such that women use physical activity as a compensatory strategy to combat potential weight gain from calories consumed during alcohol use.  相似文献

This paper chronicles the formation and development of the Global Alliance for Public Relations and Communication Management (GA) up to 2002. It sets the GA's genesis within the context of other internationalisation initiatives undertaken by the wider public relations practitioner community and draws links between the formation of the GA and the emerging phenomenon of globalisation. The paper's intent is to describe the formation of the GA from a historical perspective, to understand the forces that led to its creation and to appreciate the different drivers and motivation of founding members. These factors provide a springboard to consider some of the issues that currently challenge GA, some of which were inherent in the governance model it chose at its inception.  相似文献

The Ageing in the Growth Corridors Project was initiated as a partnership between the University of Melbourne and the Department of Health in the Northwest Metropolitan Region of Melbourne, Australia. It involved a research team working with six project officers appointed to stimulate development in relation to an aging population in the sprawling outer metropolitan growth corridors. This article identifies the key lessons learned in terms of project implementation relating to attitudinal and structural barriers to the development of an age-friendly environment in areas of rapid urban growth. The findings illustrate some of the dilemmas raised by competing program conceptions, a dynamic and changing federal/state policy context, and local resource and strategic management constraints. The partnership with the university, nevertheless, provided a point of stability and continuity for the project officers in implementing their mandate.  相似文献

Women's growing numerical representation in the professions has not necessarily translated into women being truly integrated in these occupations. Questionnaire data are used to examine whether female physicians are socially integrated in the male‐dominated profession of medicine in terms of the support they receive from their medical colleagues compared to male physicians. The literature on tokenism and homophily suggests that women in male‐dominated professions receive less support than their male colleagues, whereas the social support literature predicts that women typically receive more emotional support than men but less informational and instrumental support. The results of this study shed light on the complex and multi‐layered ways in which gender is relevant to our understanding of the extent to which co‐workers provide empathy, information and assistance to one another.  相似文献

Children who use wheelchairs have few opportunities to play sport with their able-bodied peers and siblings. This appreciative, qualitative study explored the experiences of children, families and stakeholders at a wheelchair sports club. Participant observation, research activities, focus groups and interviews were used. Sixty-three people participated (37 children, 14 stakeholders, 10 parents, two older siblings). Thematic analysis identified one unifying theme (realising potential) and four main themes: invisibility of disability; ambivalence and attraction of the chair; fun and fellowship; and thrills and skills. The Cheetahs created opportunities for meaningful participation in wheelchair sports for children with and without disabilities.  相似文献

ADE-4: a multivariate analysis and graphical display software   总被引:59,自引:0,他引:59  
We present ADE-4, a multivariate analysis and graphical display software. Multivariate analysis methods available in ADE-4 include usual one-table methods like principal component analysis and correspondence analysis, spatial data analysis methods (using a total variance decomposition into local and global components, analogous to Moran and Geary indices), discriminant analysis and within/between groups analyses, many linear regression methods including lowess and polynomial regression, multiple and PLS (partial least squares) regression and orthogonal regression (principal component regression), projection methods like principal component analysis on instrumental variables, canonical correspondence analysis and many other variants, coinertia analysis and the RLQ method, and several three-way table (k-table) analysis methods. Graphical display techniques include an automatic collection of elementary graphics corresponding to groups of rows or to columns in the data table, thus providing a very efficient way for automatic k-table graphics and geographical mapping options. A dynamic graphic module allows interactive operations like searching, zooming, selection of points, and display of data values on factor maps. The user interface is simple and homogeneous among all the programs; this contributes to making the use of ADE-4 very easy for non- specialists in statistics, data analysis or computer science.  相似文献

BACKGROUND: In Australia and internationally, women report high levels of dissatisfaction with hospital-based postnatal care. AIM: To design and implement strategies to improve hospital-based postnatal care at a Sydney metropolitan hospital. METHOD: This was an Action Research study. In Phase One, midwives considered the literature and participated in group discussions and interviews to determine their perceptions of postnatal care and the factors that facilitate or hinder the provision of quality care. In Phase Two, midwives participated in 12 working group meetings to design strategies to improve care. RESULTS: Several important principles of postnatal care were described, including building a relationship with women, meeting their individual needs, being flexible in approach and providing continuity of care. 'Listening to women', 'being there,' and 'normalising experiences and expectations' were believed to be critical to achieving these principles. A key strategy 'One to One Time' was designed to provide women with an uninterrupted period of time each day with a midwife who was available to listen to their needs and concerns and discuss issues related to their health and that of their baby. CONCLUSION: Midwives designed and implemented strategies that they believed would improve in-hospital postnatal care.  相似文献
