Community College and High School Reform: Lessons from Five Case Studies

The research reported in this paper examined a set of innovative high school programs on community college campuses. Specifically, a full-time dual enrollment program and 4 middle college high schools were studied. The authors used in-depth interviews and observational data to investigate the structure, processes, and perceptions of effectiveness of the programs. The study found multiple missions for these programs and identified common features that appear to play an important role in their formation and relative success. Although constituent perceptions of effectiveness were overwhelmingly positive, the programs did not systematically collect and analyze empirical evidence of their effectiveness.     

Changes in player characteristics and match activities in Bledisloe Cup rugby union from 1972 to 2004

Abstract

To illustrate changes in elite rugby union match activities, we analysed coded videotape recordings of the first match in each Bledisloe Cup series played between Australia and New Zealand from 1972 to 2004. We also analysed the stature and body mass of players. Effects associated with professionalism, weather conditions, and time (expressed as change per decade) were estimated with a simple generalized linear model and standardized for interpretation of magnitude. The sample size permitted confident conclusions about effects that were of at least moderate magnitude (standardized mean difference >0.6). Increases in passes, tackles, rucks, tries, and ball-in-play time were associated with the advent of professionalism, whereas there were reductions in the numbers of lineouts, mauls, kicks in play, and in mean participation time per player. Noteworthy time trends were an increase in the number of rucks and a decrease in the number of scrums. Good weather conditions were associated with increases in tries and points scored and with reductions in the number of kicks in play and participation time per player. With the advent of professionalism, players have become heavier and backs have become taller. Overall, there have been major changes in international rugby match activities and player size over the past three decades. We believe law changes and developments in match analysis, equipment technology, and player training have contributed to the changes associated with the introduction of professionalism.     

Physiological,movement and technical demands of centre-wicket Battlezone,traditional net-based training and one-day cricket matches: a comparative study of sub-elite cricket players

Abstract

This study compared physiological, physical and technical demands of Battlezone, traditional cricket training and one-day matches. Data were initially collected from 11 amateur, male cricket players (age: 22.2 ± 3.3 year, height: 1.82 ± 0.06 m body mass: 80.4 ± 9.8 kg) during four Battlezone and four traditional cricket training sessions encompassing different playing positions. Heart rate, blood lactate concentration, rating of perceived exertion and movement patterns of players were measured. Retrospective video analysis was performed to code for technical outcomes. Similar data were collected from 42 amateur, male cricket players (23.5 ± 4.7 year, 1.81 ± 0.07 m, 81.4 ± 11.4 kg) during one-day matches. Significant differences were found between Battlezone, traditional cricket training and one-day matches within each playing position. Specifically, Battlezone invoked the greatest physiological and physical demands from batsmen in comparison to traditional cricket training and one-day matches. However, the greatest technical demand for batsmen was observed during traditional cricket training. In regards to the other playing positions, a greater physiological, physical and technical demand was observed during Battlezone and traditional training than during one-day matches. These results suggest that the use of Battlezone and traditional cricket training provides players with a suitable training stimulus for replicating the physiological, physical and technical demands of one-day cricket.

Aspirations,education and inequality in England: insights from the Effective Provision of Pre-school,Primary and Secondary Education Project

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.
