Soccer in Australia underwent a series of changes following a Federal Government inquiry into its future. A report into the Structure, Governance and Management of Soccer in Australia (2003) recommended a process of structural change, aimed at repositioning and re-branding soccer as association football. The restructure yielded the replacement of the National Soccer League with the A-League, five new Australian teams and a concerted attempt to separate soccer from its ethnic ties in the antipodes. This paper examines member identification in relation to a specific A-League club’s members. Using the Sports Spectator Identity Scale (Wann & Branscombe, 1993) to measure sport fan identity in a new team context, a survey of club members of Sydney FC (n = 510), was undertaken. Survey findings indicated that members of Sydney FC reported relatively strong team identification in the first year of the new competition, with some nuanced differences based on age and income. The SSIS demonstrated a good level of fit in relation to a new sports team, although it is evident that rivalries and identification with a new team need time to develop fully.  相似文献

In this article, three librarians from Santa Fe College, the community college winner of the 2015 ACRL Excellence in Academic Libraries Award, share their successful work in information literacy instruction. While the ACRL award is given for overall achievement, this article focuses upon their creative and varied approaches to instruction, incorporating a wide blend of strategies to reach students across the college. Beginning with targeted approaches to virtual instruction, including broad use of the flipped classroom model, and building in active learning techniques, the librarians at Santa Fe College have built an instruction program that could serve as a model to community college libraries across the country.  相似文献

Biomimetic scaffolds approaching physiological scale, whose size and large cellular load far exceed the limits of diffusion, require incorporation of a fluidic means to achieve adequate nutrient/metabolite exchange. This need has driven the extension of microfluidic technologies into the area of biomaterials. While construction of perfusable scaffolds is essentially a problem of microfluidic device fabrication, functional implementation of free-standing, thick-tissue constructs depends upon successful integration of external pumping mechanisms through optimized connective assemblies. However, a critical analysis to identify optimal materials/assembly components for hydrogel substrates has received little focus to date. This investigation addresses this issue directly by evaluating the efficacy of a range of adhesive and mechanical fluidic connection methods to gelatin hydrogel constructs based upon both mechanical property analysis and cell compatibility. Results identify a novel bioadhesive, comprised of two enzymatically modified gelatin compounds, for connecting tubing to hydrogel constructs that is both structurally robust and non-cytotoxic. Furthermore, outcomes from this study provide clear evidence that fluidic interconnect success varies with substrate composition (specifically hydrogel versus polydimethylsiloxane), highlighting not only the importance of selecting the appropriately tailored components for fluidic hydrogel systems but also that of encouraging ongoing, targeted exploration of this issue. The optimization of such interconnect systems will ultimately promote exciting scientific and therapeutic developments provided by microfluidic, cell-laden scaffolds.  相似文献

Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7–9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P < 0.01) and a greater amount of time was spent in non-green environments (P < 0.01). Increased time outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.  相似文献

This study uses Grounded Theory to analyze interviews with a dozen individuals who media marathoned while going through a health struggle. The analysis addresses five major themes: engaging in escapism that enables emotional and avoidance coping, regulating cognitive expenditure by embracing challenging or comforting content, being still to heal the body, reducing emotional and cognitive strain by engaging a continuous narrative, and tapering from the marathon when feeling better. Findings suggest that media marathoning can offer beneficial cognitive, emotional, and physical regulatory opportunities for those dealing with health struggles. Furthermore, media marathoning when dealing with a health concern is a strategic and active coping strategy that has potential health benefits.  相似文献
