Educational and occupational aspirations have become an important reference point in policy debates about educational inequality. Low aspirations are presented as a major barrier to closing educational attainment gaps and increasing levels of social mobility. Our paper contributes to this on-going debate by presenting data on the educational aspirations of students from the Effective Provision of Pre-School, Primary and Secondary Education Project in England. We analyse factors that help predict students holding high aspirations. Our findings reveal generally high aspirations across all students but also differences by income group and other background factors. We evaluate the significance of these findings for the existing literature and public policy discussions about the importance of raising educational aspirations. In particular, we question the way in which low aspirations are framed by policy-makers as a major problem in debates around educational inequality. 相似文献

In this paper I offer an activist's own account of a grass-roots club I helped found in 1992 and I remain an active member of today. The Easton Cowboys and Cowgirls are an amateur sports club based in inner-city Bristol. We have not got our own ground and most people would not have heard of us. We play at the very lowest rung of UK mass participation sport – in the Sundays and Saturday leagues, on the muddy pitches and municipal sports grounds where week after week men and women run around, for their own enjoyment without expectation of financial gain of any sort. My aim is to explain why the Cowboys and Cowgirls are an extraordinary club, outlining some of the extraordinary things it has done, some of which reside beyond the imagination of most professional clubs. It is only now, 20 years after we first formed, that we can stand back and admire what we have achieved and appreciate the role we have played in developing a small but growing network of teams that stand at odds with the way society is organized and (to a certain extent) the mediated, poisoned world of professional sport. 相似文献

Abstract Analysis of variability and progression in performance of top athletes between competitions provides information about performance targets that is useful for athletes, practitioners, and researchers. In this study, 724 official finals times were analysed for 120 male and 122 female Paralympic swimmers in the 100-m freestyle event at 15 national and international competitions between 2004 and 2006. Separate analyses were performed for males and females in each of four Paralympic subgroups: S2–S4, S5–S7, S8–S10 (most through least physically impaired), and S11–S13 (most through least visually impaired). Mixed modelling of log-transformed times, with adjustment for mean competition times, was used to estimate variability and progression. Within-swimmer race-to-race variability, expressed as a coefficient of variation, ranged from 1.2% (male S5–S7) to 3.7% (male S2–S4). Swimming performance progressed by approximately 0.5% per year for males and females. Typical variation in mean performance time between competitions was ~1% after adjustment for the ability of the athletes in each competition, and the Paralympic Games was the fastest competition. Thus, taking into account variability, progression, and level of competition, Paralympic swimmers who want to increase substantially their medal prospects should aim for an annual improvement of at least 1–2%. 相似文献

Theoretical analyses within the broad field of social learning research give mixed conclusions on whether the shape of a diffusion
curve can be used to infer that a learned trait increases through social or asocial learning. Here we explore how factors
such as task structure (e.g., multiple-step tasks), task abandonment, subgoal learning, and neophobia affect the shape of
the diffusion curve for both asocially learned and socially learned behavior. We demonstrate that, whereas social learning
increases the likelihood of S-shaped curves, sigmoidal patterns can be generated by entirely asocial processes, and cannot
be reliably interpreted as indicators of social learning. Our findings reinforce the view that diffusion curve analysis is
not a reliable way of detecting social transmission. We also draw attention to the fact that task structure can similarly
confound interpretation of network-based diffusion analyses, and suggest resolutions to this problem. Supplemental materials

Pacing offers a potential avenue for enhancement of endurance performance. We report here a novel method for characterizing pacing in 800-m freestyle swimming. Websites provided 50-m lap and race times for 192 swims of 20 elite female swimmers between 2000 and 2013. Pacing for each swim was characterized with five parameters derived from a linear model: linear and quadratic coefficients for effect of lap number, reductions from predicted time for first and last laps, and lap-time variability (standard error of the estimate). Race-to-race consistency of the parameters was expressed as intraclass correlation coefficients (ICCs). The average swim was a shallow negative quadratic with slowest time in the eleventh lap. First and last laps were faster by 6.4% and 3.6%, and lap-time variability was ±0.64%. Consistency between swimmers ranged from low-moderate for the linear and quadratic parameters (ICC = 0.29 and 0.36) to high for the last-lap parameter (ICC = 0.62), while consistency for race time was very high (ICC = 0.80). Only ~15% of swimmers had enough swims (~15 or more) to provide reasonable evidence of optimum parameter values in plots of race time vs. each parameter. The modest consistency of most of the pacing parameters and lack of relationships between parameters and performance suggest that swimmers usually compensated for changes in one parameter with changes in another. In conclusion, pacing in 800-m elite female swimmers can be characterized with five parameters, but identifying an optimal pacing profile is generally impractical. 相似文献

Identifying match events that are related to match outcome is an important task in football match analysis. Here we have used generalised mixed linear modelling to determine relationships of 16 football match events and 1 contextual variable (game location: home/away) with the match outcome. Statistics of 320 close matches (goal difference ≤ 2) of season 2012–2013 in the Spanish First Division Professional Football League were analysed. Relationships were evaluated with magnitude-based inferences and were expressed as extra matches won or lost per 10 close matches for an increase of two within-team or between-team standard deviations (SD) of the match event (representing effects of changes in team values from match to match and of differences between average team values, respectively). There was a moderate positive within-team effect from shots on target (3.4 extra wins per 10 matches; 99% confidence limits ±1.0), and a small positive within-team effect from total shots (1.7 extra wins; ±1.0). Effects of most other match events were related to ball possession, which had a small negative within-team effect (1.2 extra losses; ±1.0) but a small positive between-team effect (1.7 extra wins; ±1.4). Game location showed a small positive within-team effect (1.9 extra wins; ±0.9). In analyses of nine combinations of team and opposition end-of-season rank (classified as high, medium, low), almost all between-team effects were unclear, while within-team effects varied depending on the strength of team and opposition. Some of these findings will be useful to coaches and performance analysts when planning training sessions and match tactics. 相似文献
