An objective method for depicting team performance in elite professional rugby union

Using a two-study approach, we examined a methodology for objectively depicting team performance and form in a professional rugby union side. Study 1 developed standardized indicators to examine a team's performance in a single match relative to their previous matches over a domestic season via a performance report and form chart. This resulted in standardized performance indicators that provided instant and coherent feedback on the team's performance relative to previous standards. Study 2 then utilized this methodology to compare a match between two professional sides, played the following season, to assess the extent to which the performance by one team affected that of the other. Comparison of the two teams' performances, for the match they played against each other, identified a drop in relative performance (against previous standards) for both teams on the same performance indicators. This appeared to be due to the match being a close, hard-fought contest particularly in the tackle and around the gain-line. The findings of the two studies suggest an accurate and viable methodology for depicting team performance that is superior to the global measures previously adopted. Presenting teams' current standardized performances (i.e. form) on a single visual scale also has utility for coaches within an applied setting. Future research should further investigate the effect of one team's performance on another through both individual and team outcomes.

Preparing School Counselors to Promote Academic Development

Reform in school counseling over the last decade has focused on how school counselors can contribute to the academic development of K–12 students. Consensus in this matter has yet to be achieved, and recommendations about how best to prepare preservice K–12 school counselors for this objective have been incomplete. The authors describe content and supervised experiences from a preservice course designed to prepare school counselors to promote student academic development.

Prolonged static stretching does not influence running economy despite changes in neuromuscular function

The aim of this study was to examine the acute effects of prolonged static stretching (SS) on running economy. Ten male runners (VO2(peak) 60.1 +/- 7.3 ml x kg(-1) x min(-1)) performed 10 min of treadmill running at 70% VO2(peak) before and after SS and no stretching interventions. For the stretching intervention, each leg was stretched unilaterally for 40 s with each of eight different exercises and this was repeated three times. Respiratory gas exchange was measured throughout the running exercise with an automated gas analysis system. On a separate day, participants were tested for sit and reach range of motion, isometric strength and countermovement jump height before and after SS. The oxygen uptake, minute ventilation, energy expenditure, respiratory exchange ratio and heart rate responses to running were unaffected by the stretching intervention. This was despite a significant effect of SS on neuromuscular function (sit and reach range of motion, +2.7 +/- 0.6 cm; isometric strength, -5.6% +/- 3.4%; countermovement jump height -5.5% +/- 3.4%; all P < 0.05). The results suggest that prolonged SS does not influence running economy despite changes in neuromuscular function.     

Everyday life and everyday learning: the ways in which pre-service teacher education curriculum can encourage personal dimensions of teacher identity

This article presents and discusses the findings of a research project, the main objective of which is to identify curriculum components that promote personal development as a nuclear part of teacher professional identity formation through pre-service teacher education. Curriculum is viewed as an ecological scenario with different subsystems and both as formal and informal. Identity formation is conceived as an ever-provisional result of a double transaction: the biographical one and the relational one. The curricula of four different historical periods of pre-service teacher education in Portugal and the professional identity of teachers trained within them were characterised through collection and analysis of documents and biographical narratives. Crossing results from the four periods, the quality of school climate emerges as an important variable to the quality of the teachers’ identity. The lifelong learning ethos seems to emerge when the training curriculum connects everyday learning with everyday life, namely by urging the students’ involvement in school life, peer learning activities and peer and teacher educators’ informal learning activities.     

热镀锌板表面锌层起泡原因探讨

热镀锌板在冲压成零件时,局部的镀锌层出现约3mm大小的起泡,将起泡用手术刀切开,撕下锌层,采用扫描电镜对起泡部位的基体以及锌层靠基体的表面进行了分析,对比分析正常部位纯锌层与基体之间的抑制层。结果表明:正常部位的抑制层为细小弥散分布的Fe2Al5颗粒,产生起泡的缺陷部位未见到抑制层颗粒,锌层与基板之间存在局部聚集的Al2O3夹渣,冲压成型后,夹渣松动,锌层与基板分离,导致锌层起泡。     

Generation Psy: Student characteristics and academic achievement in a three-year problem-based learning bachelor program

This study investigated the simultaneous impact of demographic, personality, intelligence, and (prior) study performance factors on students' academic achievement in a three-year academic problem-based psychology program. Information regarding students' gender, age, nationality, pre-university education, high school grades, Big Five personality traits, intelligence (i.e., numerical, verbal, spatial), observed learning activities, and self-study time was collected among almost 1800 students enrolled in this psychology bachelor program at Erasmus University Rotterdam between 2003 and 2009. Academic achievement was measured by students' yearly number of acquired credit points, a course test, and a knowledge progress test. Multiple regression analyses showed that observed learning activities, first- and second-year performance, high school grades, conscientiousness, and verbal ability were most strongly and consistently related to academic achievement in the bachelor. Other student factors also contributed to academic achievement, but their influence was less prominent and mainly restricted to the first year. These results suggest that (prior) educational achievements and observable learning activities are most important for academic success in a problem-based learning bachelor program.     

Predictors of Familial Acculturative Stress in Asian American College Students

The authors examined the predictors of familial acculturative stress in 85 Asian American college students. Participants were primarily 1st‐ and 2nd‐generation U.S. citizens. Results showed that perceived acculturative family conflict and family intragroup marginalization were related to higher levels of familial acculturative stress for participants. Family intragroup marginalization accounted for a statistically significant proportion of the variance in familial acculturative stress after all variables were controlled. The findings emphasize the need to recognize culture‐specific stressors of college students. Implications for college counselors are discussed.
