Landing techniques in volleyball

Knee injuries such as anterior cruciate ligament lesions and patellar tendonitis are very frequent in volleyball, and are often attributed to micro traumas that occur during the landing phase of airborne actions. The aim of the present study was to compare different jumping activities during official men's and women's volleyball games. Twelve top-level matches from the Italian men's and women's professional leagues were analysed. The jumps performed during the games were classified according to the landing technique used by the player (left or right foot or both feet together), court position, and ball trajectory. Chi-square analyses were performed to detect differences in landing techniques between the sexes, court positions, and trajectories when serving, attacking, blocking, and setting. Significant differences (P?相似文献   

Factor Structure and Construct Validity of the Counselor Skills Personal Development Rating Form

The authors completed an exploratory factor analysis of the scores of 248 counselors‐in‐training on the Counselor Skills Personal Development Rating Form (CSPD‐RF; M. B. Wilbur, 1991). Participants' counseling program was accredited by the Council for Accreditation of Counseling and Related Educational Programs at a midsize western university. The authors of the CSPD‐RF hypothesized that the CSPD‐RF measured 2 factors: (a) personal development and (b) skills development. Factor analysis yielded 4 factors (Emotional Sensitivity, Basic Listening Skills, Multicultural Skills, and Influencing Skills), accounting for 58.4% of the total variance, thus providing some support for the construct validity of the CSPD‐RF.     

Teachers’ perspectives on integration of visually impaired children

ABSTRACT

The aim of this article is to show the result of research into the situation of the integration of visually impaired children in Seville (Spain). This work refers to both classroom and peripatetic teachers’ perspectives. We have worked with four peripatetic teachers and nine classroom teachers from Seville. We have used qualitative methodological procedures for data collection and analysis. The results indicate that classroom organization is the most important problem in integration, and within this problem the relationship between classroom and peripatetic teachers becomes a fundamental issue.     

A Remote Sensing Class Exercise to Study the Effects of El Niño in South America

Satellite remote sensing techniques can be used for conducting environmental change detection studies following a natural disaster. Modern computer technology and free access to global satellite imagery allows educators to introduce undergraduate students to the fields of remote sensing and encourage their scientific participation through a research assignment that also serves as an educational exercise. The undergraduate physical science laboratory manuals used in higher education that contain printed remote sensing material often fail to effectively achieve these goals. This class exercise utilizes digital satellite imagery for studying the floods that resulted in the Paraná River region in South America during El Niño 1997–98. In addition, it examines vegetation cover and spectral profiles from the study area in order to further understand and assess the changes that were caused by this recurrent climatic anomaly.     

Resisting the marginalization of science in an urban school: Coactivating social,cultural, material,and strategic resources

This study describes the resources and strategies middle school teachers, urban fellows, and a district science staff developer coactivated to resist the marginalization of science in a high‐poverty, low‐performing urban school. Through critical narrative inquiry, I document factors that marginalized science in three teachers' classrooms. The narratives show that constraints related to cultural, material, and social resources contributed to a more global symbolic resource constraint, the low status and priority of science in the school. The narratives develop a new category of strategic resources embodied or controlled by others and leveraged to improve students' opportunities to learn science. Attention to a broader array of resources, including social, symbolic, and strategic resources, helps to excavate some of the inertial forces that might derail efforts to teach for social justice. The findings provide a sense of how and why teachers might activate resources to resist the marginalization of science in their classrooms. © 2009 Wiley Periodicals, Inc.

The (Re)Emergence of a Religio-Spiritual Self-Cultivation Focus in Asian Martial Arts Monographs Published in Spain (1906–2009)

This article presents one analytical theme emerging from a bibliometric and content analysis of an annotated bibliography, compiled by the first author, comprising 1564 Asian martial arts monographs published in Spain between 1906 and 2009. The analysis reveals that the use of Asian martial arts and religio-spiritual self-cultivation practices, while very old in their indigenous South East Asian context, only appeared in published texts in Spain from the 1960s and this theme has been increasingly written about in the last two decades. In our analytical discussion, we contextualise this shift from a socio-historical perspective, focusing on three aspects: first and second, how this shift in focus in Asian Martial Art publishing fits with the patterns of societal secularisation in Spain, the rise of the New Age movement and counter-cultural spiritualities across Western culture; third, we comment on how, from this broader socio-historical context, Asian martial arts were well placed to fill ‘cultural spaces’ created by these changes.     

History of education in Brazil: the construction of a knowledge field

This article analyses the general characteristics of the construction of the field of history of education in Brazil. To do so, it highlights the existing historiography and aims to describe the process of institutionalisation of this knowledge field, which, in general terms, has been focused on the area of teacher training. Since the nineteenth century, however, it has also been possible to identify systematic historiographical efforts in Brazil that are not directly related to the school system, but rather to the teaching of and research into the history of education within Brazilian universities. The article addresses the organisation of the field, the ways in which it has been structured and the strategies of academic legitimisation employed to achieve this. These include the regular production of dissertations and doctoral theses, the publication of books and journals, academic events and the creation of research groups and scientific associations, through which research findings have found national and international circulation. This set of indicators creates conditions for an understanding of the expansion and reconfiguration of the field of history of education that began in the 1980s, as well as of the challenges this phenomenon presents to current historiography and teacher training in Brazil.
