High bar swing performance in novice adults: effects of practice and talent

An individual's a priori talent can affect movement performance during learning. Also, task requirements and motor-perceptual factors are critical to the learning process. This study describes changes in high bar swing performance after a 2-month practice period. Twenty-five novice participants were divided by a priori talent level (spontaneous-talented [ST] and nonspontaneous-talented [NST]) and compared to experienced gymnasts. Additionally, we assessed their perception of their performance level before and after practice. We defined three events independently for hip (H) and shoulder (S) angle joints and for the lag between consecutive events (phases [P]): the smallest angle during downswing (P1H, P1S), the largest angle after P1 (P2H, P2S), and the smaller angle during upswing (P3H, P3S). Movement performance variables were the maximum elevation on the downswing (Pi) and the upswing (Pf), and the total path between both (swing amplitude). Data were collected during pre- and postpractice sessions by two video cameras. At the end of both sessions, participants drew a sketch to represent their perception of their performance level relative to the Pi, Pf and the hip events. Results showed a similar practice effect in the swing amplitude in both novice groups. However the ST group 's performance and perception variables on the downswing improved more than the NST group due to practice. This study suggests that (a) downswing improvements were easier than in the upswing, possibly due to familiarity of the visual reference in combination with proprioceptive feedback; and (b) being ST may involve a better orfaster gain in perception of self-action compared to NST.     

远景分析：互联网时代

8年前,我和我的同事完成了OCLC第一篇会员报告《审视发展环境认清前景趋势》,当时我们的目的是了解正在增长的网络信息消费者的态度和习惯。报告中我们探寻在早期互联网信息环境下的三个主题：自助服务、用户满意度和无缝连接。该报告的研究还是非常肤浅的,但是它引发了大量的讨论,OCLC也出现了对信息消费者的一系列研究。     

30 years after Bayh–Dole: Reassessing academic entrepreneurship

On the 30th anniversary of enactment of the Bayh–Dole Act in the U.S., we consider the rationale for academic entrepreneurship and describe the evolving role of universities in the commercialization of research. We also discuss and appraise the effects of legislative reform in several OECD countries relating to academic entrepreneurship. The article synthesizes papers from the special section and outlines an agenda for additional research on various aspects of academic entrepreneurship in terms of system, university and individual levels. We also consider measurement and methodological issues that must be addressed in additional research.     

博士生教育国际化的新形式:欧洲博士学位

研究了欧洲博士学位的发展历程及模式,分析了建立欧洲博士学位的必要条件,讨论了阻碍欧洲博士学位发展的因素并提出了相关建议.文章指出,尽管自欧盟成立之初就提出了欧洲博士学位的概念,但直到最近才开始着手解决这一问题.这是包括欧盟委员会、欧洲大学协会、欧洲能授予博士学位的高等教育机构代表和博洛尼亚进程等多方努力的结果.虽然欧洲联合博士学位的工作已取得重要进展,但其合法价值获得真正认可还需要很长的路.由于部分欧盟成员国各国的法律规定以及欧洲高等教育体系内仍然广泛存在着"鼓励学术保护而非促进合作"的保守思想,导致产生了一些问题.阻碍新的联合博士学位发展的两个主要原因是:错误地将国际流动作为目标,而不是将其作为博士生教育的一个策略;广泛担忧一体化将破坏欧洲博士课程的多样化,导致出现同质化.     

Development of Equity Preferences in Boys and Girls Across Adolescence

The aim of the current study was to examine the development of equity preferences across adolescence, for boys and girls separately. Participants from 8 to 18 years old (M = 14.09 years; N = 1,216) played four economic allocation games. Analyses revealed a decrease in equity preferences with age and this decrease was stronger for boys than for girls. There was also an age‐related increase in the preference for efficient outcomes (i.e., maximization of total available resources), which was again stronger for boys than for girls. Overall, although equity remains as a strong social norm, adolescents are decreasingly strict in adhering to the equity norm and show increasing flexibility in equity preferences.     

Learning to Love Reading: A Self-Study on Fostering Students' Reading Motivation in Small Groups

This study explores the relationship between small, differentiated reading groups and fourth-grade students' reading motivation. Using self-study methodology, the author examined her own process of implementing these reading groups through two cycles of action research. Data were analyzed from two different administrations of the Motivations for Reading Questionnaire, as well as from the author's narrative journal entries, written student reflections, small-group and individual interviews, and a critical friend's observations. Findings indicated that small, differentiated reading groups that emphasized social interaction and student choice led to a class culture of reading and promoted students' reading motivation. Students linked their learning in these groups to their written assignments and tended to devalue the group discussions. In addition, implementing the reading groups minimized the author's own performance gap and contributed to greater satisfaction in her own practice. These findings have implications for the design and implementation of differentiated reading groups, as well as for those who support novice teachers.     

El lenguaje y las matemáticas en la propuesta curricular para la educación infantil del Department d'Ensenyament de la Generalitat de Catalunya

La propuesta curricular de la Generalitat de Catalunya y el modelo curricular de la LOGSE son dos realizaciones sucesivas, y por ese orden, del mismo planteamiento. Incluimos aquí esta propuesta curricular como la primera de otras posibles que versen sobre el tratamiento que reciben los códigos de representación en la reforma que viene y como un elemento mas del debate científico-profesional al que desde ahora invitamos a nuestros lectores.     

Kulturelle Bildung an den Schulen in Deutschland

Previous research findings suggest that school types differ in terms of their extracurricular art-aesthetic offers and that at “Gymnasien” (grammar schools) and “Comprehensive Schools” conditions for art-aesthetic education are particularly favorable. Furthermore, at all-day schools they seem to be more favorable than at other schools. To see whether these findings can be confirmed and differences between school types can be found even after controlling for relevant school characteristics, a nationwide representative survey of school leaders at state schools was analyzed. Three dimensions of art-aesthetic education were examined: extracurricular art-aesthetic offers, cooperation with out-of-school cultural institutions and, finally, school profiles. The results allow for a differentiation and complementation of former findings concerning the specific conditions at different school types regarding the advancement of art-aesthetic experiences, because characteristics such as all-day-school organization, school size or resources were considered.
