ABSTRACTThis article suggests that situations in which multiple research teams are convened under similar conditions present an opportunity to discover factors that lead to productive collaboration. It argues that social network analysis of research team outputs becomes more valuable when paired with data about research participant perceptions; and that any variables used as indicators of collaboration need to be calibrated using datasets from multiple studies with cross-team comparisons. The article provides an example of the kind of methodology needed to achieve this, describing a study with data from four research teams based at an Australian university campus, reporting their research performance over four years under conditions in which many variables were controlled and with results augmented by a survey of participant perceptions. Findings from the study indicate that there were exceptions to hypothesized associations between participant perceptions of collaboration and specific social network analysis measures over co-authorship data. The article suggests that, given the methodological challenges of studying research teams in the field, multiple datasets combining findings such as those in the present study are a path towards the development of indicators of productive higher education research collaboration. 相似文献

ABSTRACTInterval exercise training is increasingly recommended to improve health and fitness; however, it is not known if cardiovascular risk is different from continuous exercise protocols. This systematic review with meta-analyses assessed the effect of a single bout of interval exercise on cardiovascular responses that indicate risk of cardiac fibrillation and infarction compared to continuous exercise. Electronic databases Medline, CINAHL, Embase, Scopus and Cochrane were searched. Key inclusion criteria were: (1) intervals of the same intensity and duration followed by a recovery period and (2) reporting at least one of blood pressure, heart rate variability, arterial stiffness or function. Cochrane Risk of Bias tool and GRADE approach were used. Meta-analyses found that systolic blood pressure responses to interval exercise did not differ from responses to continuous exercise immediately (MD 8 mmHg [95% CI ?32, 47], p = 0.71) or at 60 min following exercise (MD 0 mmHg [95% CI ?2, 1], p = 0.79). However, reductions in diastolic blood pressure and flow-mediated dilation with interval exercise were observed 10–15 min post-exercise. The available evidence indicates that interval exercise does not convey higher cardiovascular risk than continuous exercise. Further investigation is required to establish the safety of interval exercise for clinical populations. 相似文献

Little is known about how children's value priorities develop over time. This study identifies children's value priority profiles and follows their development during middle childhood. Australian children (N = 609; ages 5–12 at Time 1) reported their values over 2 years. Latent Transition Analysis indicated four profiles: Social-Focus, Self-Focus, Growth-Focus and Undifferentiated. Within person development was characterized by profile stability or transfer to the Social-Focus profile. Younger children were more likely to have an Undifferentiated profile (or Self-Focus among boys) than older ones. Girls were more likely to have a Social-Focus profile or transfer to it, and less likely to have a Self- or Growth-Focus profile than boys. Social-Focus profile membership over time predicted more prosocial and less aggressive behavior. 相似文献

Connections have been drawn between masculinity, muscularity and physical or social status in sport. Not only are sporting bodies often related to masculinity but also to whiteness, leading to the devaluing of Asian boys' bodies and sporting experiences. This paper draws on three British Asian teenage boys' visual and verbal narratives to enquire how they negotiate these connections in their physical education and recreational sport experiences. Bourdieu's notion of capital is used to make sense of boys' ways of investing in their bodies to manage their status in school. Drawing from focus-group interviews which used participant-driven photography and photo elicitation techniques, the research indicates how three boys invested in their bodies by doing particular types of physical activity that would enable them to develop muscularity, fitness and/or motor competence, to attain or retain physical and social capital in school. Along the way, they add pertinent comments on the intersections of masculinity and ethnicity in constructing and performing a sporting body. 相似文献

Girls’ active identities: navigating othering discourses of femininity,bodies and physical education
Joanne Hill 《Gender and education》2015,27(6):666-684
Within physical education and sport, girls must navigate discourses of valued athletic and gendered bodies that marginalise or ‘other’ non-normative performances through systems of surveillance and punishment. The purpose of this paper is to share girls’ perspectives on how these discourses affected their gender performances and activity engagement. Students aged 13–14 in one ethnically diverse UK secondary school were invited to create a photo diary of the physical activities they engaged in. Photo-elicitation interviews in small groups followed. The girls positioned themselves as physically active but had to carefully manage their activity choices and gender performances in a single-sex physical education environment that regulated deviation from the fit, slender, girly-girl. Although the girls demonstrate the difficulty of resisting, they indicate moments of positioning themselves against norms that suggest the possibilities of shifting gendering processes. The paper points out the importance of listening to ‘other’ girls’ narratives in building positive physical education engagements. 相似文献
