Attempts to make higher education more equitable more readily succeed at the aggregate (sector) level than at the institutional, with students from disadvantaged groups being overrepresented in low-status institutions. It is suggested that this is because policies of ‘fairness’ (i.e. proportional representation) dominate the contemporary policy framework and are strongly resisted by elite universities. However, using the Australian higher education sector as an example, this paper argues that equity policy is actually a mix of ‘proportional fairness’ and ‘inclusion’ and elite institutions resist not because the policy is deficient but because it might actually work. An alternative approach to higher education equity policy is proposed; one which requires elite institutions to engage meaningfully with disadvantaged students but allows them to retain their status advantage. 相似文献

Faculty, librarians, students, and administrators are all faced with questions concerning permitted uses of licensed content. Rather than wrangle with the complexities of copyright, many would prefer a simple automated solution. The Stanford Center for Legal Informatics created such a tool through a research project that evolved into SIPX, a commercial copyright service. The Copyright Clearance Center (CCC) created a product concept but faced challenges in converting it into an academic product. 相似文献

Repeated high-intensity exercise in professional rugby union 总被引:1,自引:1,他引:0
The aim of the present study was to describe the frequency, duration, and nature of repeated high-intensity exercise in Super 14 rugby union. Time-motion analysis was used during seven competition matches over the 2008 and 2009 Super 14 seasons; five players from each of four positional groups (front row forwards, back row forwards, inside backs, and outside backs) were assessed (20 players in total). A repeated high-intensity exercise bout was considered to involve three or more sprints, and/or tackles and/or scrum/ruck/maul activities within 21 s during the same passage of play. The range of repeated high-intensity exercise bouts for each group in a match was as follows: 11-18 for front row forwards, 11-21 for back row forwards, 13-18 for inside backs, and 2-11 for outside backs. The durations of the most intense repeated high-intensity exercise bouts for each position ranged from 53 s to 165 s and the minimum recovery periods between repeated high-intensity exercise bouts ranged from 25 s for the back row forwards to 64 s for the front row forwards. The present results show that repeated high-intensity exercise bouts vary in duration and activities relative to position but all players in a game will average at least 10 changes in activity in the most demanding bouts and complete at least one tackle and two sprints. The most intense periods of activity are likely to last as long as 120 s and as little as 25 s recovery may separate consecutive repeated high-intensity exercise bouts. The present findings can be used by coaches to prepare their players for the most demanding passages of play likely to be experienced in elite rugby union. 相似文献

In this study, we investigated the relationship between physiological, anthropometric, and skill qualities and playing performance in professional rugby league players. Fifty-eight high-performance rugby league players underwent measurements for anthropometry (height, body mass, sum of seven skinfolds), physiological (speed, change of direction speed, lower body muscular power, repeated-sprint ability, prolonged high-intensity intermittent running ability, and estimated maximal aerobic power), technical skill (tackling proficiency, draw and pass proficiency), and perceptual skill (reactive agility, pattern recall, pattern prediction) qualities. National Rugby League matches were coded for attacking (e.g. line breaks, try assists, etc.) and defensive (e.g. missed tackles, tackling efficiency, etc.) statistics commonly used to assess rugby league playing performance. The number of line break assists was significantly associated (P < 0.05) with greater playing experience (r = 0.36), dual-task draw and pass proficiency (r = 0.54), reactive agility (r = 0.29), and pattern recall (r = 0.32) and prediction (r = 0.28) ability, while faster speed over 40 m (r = -0.42) was associated (P < 0.05) with a higher number of tries scored. Greater age and playing experience, better lower body muscular power, and faster 10 m and 40 m speed were significantly associated (P < 0.05) with the number of tackle attempts (positive), tackles completed (positive), and proportion of missed tackles (negative). These findings demonstrate that well-developed physical and skill qualities are associated with effective playing performance in National Rugby League players. 相似文献

We tested the predictive validity of the recently validated three-dimensional model of performance anxiety (Chang, Hardy, & Markland, 2009) with elite tae-kwon-do competitors (N = 99). This conceptual framework emphasized the adaptive potential of anxiety by including a regulatory dimension (reflected by perceived control) along with the intensity-oriented dimensions of cognitive and physiological anxiety. Anxiety was assessed 30 min before a competitive contest using the Three-Factor Anxiety Inventory. Competitors rated their performance on a tae-kwon-do-specific performance scale within 30 min after completion of their contest. Moderated hierarchical regression analyses revealed initial support for the predictive validity of the three-dimensional performance anxiety model. The regulatory dimension of anxiety (perceived control) revealed significant main and interactive effects on performance. This dimension appeared to be adaptive, as performance was better under high than low perceived control, and best vs. worst performance was associated with highest vs. lowest perceived control, respectively. Results are discussed in terms of the importance of the regulatory dimension of anxiety. 相似文献

Gender equity issues remain a challenge in science, technology, engineering, and mathematics (STEM) fields, where women are highly underrepresented. As integrated STEM instruction becomes increasingly popular in elementary and middle school classrooms, it is important to consider whether the small group activities that are commonplace in STEM instruction support the equitable participation of young girls. This study builds on the existing body of literature to better understand how gender is related to student participation in small group STEM activities and whether students participate differently in science and engineering activities. A single embedded case study was used to explore the experiences of four students aged 10–11 years as they participated in small group work within an integrated STEM unit in their fifth-grade classroom. Two girls and two boys worked together throughout the unit to explore science content related to electromagnetism and apply their content knowledge to an engineering design challenge. Video and audio of students' small group interactions were analyzed using an observation protocol to code their participation in each 3-min segment of STEM activity. Student- and case-level analyses were used to identify patterns of interaction based on gender and type of activity (science vs. engineering). Findings suggest that boys and girls participate in small group STEM activities in different ways, adopting distinct roles within their group. In addition, students displayed divergent patterns of interaction in science- and engineering-focused lessons, suggesting that students need additional practice and support in navigating between science and engineering in integrated STEM units. 相似文献

An important goal for educators is to foster student engagement in order to support a sense of valuing and aspiring to higher levels of education. To value education, students need to perceive that they are welcome, express their ideas and engage meaningfully in each education space they enter. Therefore, ‘pupil voice’ has the potential to become an important influencing factor regarding the degree to which students become self-regulated learners, value educationand consequently support their aspirations and build their expectations to go on to university. This study examines the role pupil voice plays in building cognitive and emotional engagement, and whether this, in turn, builds desire for further study and expectations for university entry. Pupil voice is operationalised as the extent to which the student feels heard, involved and supported by the school community. Student survey data was collected (N = 542) from a low socioeconomic status region of the southwest corridor of metropolitan Perth, Western Australia. Structural equation modelling substantiated our serial mediation hypothesis. For students, a discernible pupil voice significantly and positively increased cognitive engagement (self-regulated learning), which increased emotional engagement (valuing education) that, in turn, increased university desires, which led to increased university expectations. The results of this study underscore the importance of policies and practical interventions designed to develop strong student–teacher relationships, where students feel they are both seen and heard. 相似文献

The author conducted an action research study in his ninth grade English classroom in order to help the boys in his class to be more engaged. He decided to enable students to make more choices in the reading and writing activities so that both boys' and girls' literacies could be valued. He used independent reading and literature circles to help boys find books that met their diverse interests, and designed writing assignments which enabled students to choose topics which matched their out‐of‐school interests. Boys and girls benefited from such choice. He observed boys, especially, engaging in more literate behaviours—such as talking about books and sharing each others' writing. 相似文献
