Coordination pattern of baseball pitching among young pitchers of various ages and velocity levels

This study compared the whole-body movement coordination of pitching among 72 baseball players of various ages and velocity levels. Participants were classified as senior, junior, and little according to their age, with each group comprising 24 players. The velocity levels of the high-velocity (the top eight) and low-velocity (the lowest eight) groups were classified according to their pitching velocity. During pitching, the coordinates of 15 markers attached to the major joints of the whole-body movement system were collected for analysis. Sixteen kinematic parameters were calculated to compare the groups and velocity levels. Principal component analysis (PCA) was conducted to quantify the coordination pattern of pitching movement. The results were as follows: (1) five position and two velocity parameters significantly differed among the age groups, and two position and one velocity parameters significantly differed between the high- and low-velocity groups. (2) The coordination patterns of pitching movement could be described using three components, of which the eigenvalues and contents varied according to age and velocity level. In conclusion, the senior and junior players showed greater elbow angular velocity, whereas the little players exhibited a wider shoulder angle only at the beginning of pitching. The players with high velocity exhibited higher trunk and shoulder rotation velocity. The variations among groups found using PCA and kinematics parameter analyses were consistent.     

In a practical mood: Studying for a profession in the changing kibbutz

The influence of recent social and economicchanges in the Israeli kibbutz on the prolongedstage of youth was examined with respect tohigher education. The young people on thekibbutz of the late 1990s appear lessmoratorial and more instrumental about theirfuture and commence higher education earlierthan in previous age cohorts. When starting tostudy, their educational and professionalprospects are crystalized as those of thenon-kibbutz student. Most of them opt foracademic, degree-granting studies, but a higherpercentage than among the general populationprefer vocation-oriented colleges to theresearch oriented universities. In choosingfields of study, they prefer more appliedstudies like engineering, social services andpractical arts and are less likely to choosesciences and the humanities. De-communalizationand economic instability of the kibbutz,inadequate preparation in kibbutz high schoolsfor the competitive admission to theuniversities, exposure to a restricted range ofoccupations during adolescence, and lack of acultural tradition supportive of elitiststudies may explain this practical mood, moresalient among kibbutz women.     

全球化背景下西方文化对我国青年价值观的影响

全球化是当代世界最重要、最迅猛的发展趋势，它已经广泛地渗透到各国的政治、经济、化等许多生活领域。全球化背景下的西方化向我国的大举挺进，深刻地影响了并还将继续深远地影响着我国青年价值观的变化和发展。因此，对西方化的反思和对青年价值观的教育与培养已成为我国当前发展的重大课题。     

‘Upturned participation’ and youth work: using a Critical Utopian Action Research approach to foster engagement

ABSTRACT

This article reflects on how participatory processes inspired by action research hold a genuine potential for developing social educational work in a more democratic way. We present our concept of ‘Upturned Participation’, which is built upon the methodological framework of Critical Utopian Action Research. First Critical Utopian Action Research is introduced briefly, including a presentation of the core method of the action research approach. We then present an extract from an action research project aimed at creating space for participation for marginalized young people in the area of Copenhagen. On this basis, we reflect on how the ideas of the young people could influence the field of social work. The article addresses contemporary challenges and opportunities for creating development in the field of youth work or social work through participatory processes with marginalized young people.

Predictors of Delinquent Behaviors Among Latino Youth

This study used an ecological framework to examine predictors of delinquent behaviors among 91 sixth-grade Latino youth. Both proximal and distal contextual factors were assessed to determine their impact on various forms of delinquency, such as violent behaviors, violent thoughts, substance abuse, and general delinquency (e.g., skipping school). Attitudes toward school, mobility (number of moves to new schools and neighborhoods), and exposure to community violence were distal variables, whereas attachment to parents and attachment to peers were considered more proximal variables. Environmental experiences or exposure to distressing community violence was the strongest predictor of delinquent outcomes. The results were discussed in terms of school officials' developing linkages with the community to promote safe environments for youth.     

Negotiating queer and religious identities in higher education: queering ‘progression’ in the ‘university experience’

This article addresses the negotiation of ‘queer religious’ student identities in UK higher education. The ‘university experience’ has generally been characterised as a period of intense transformation and self-exploration, with complex and overlapping personal and social influences significantly shaping educational spaces, subjects and subjectivities. Engaging with ideas about progressive tolerance and becoming, often contrasted against ‘backwards’ religious homophobia as a sentiment/space/subject ‘outside’ education, this article follows the experiences and expectations of queer Christian students. In asking whether notions of ‘queering higher education’ (Rumens 2014 Rumens, N. 2014. “Queer Business: Towards Queering the Purpose of the Business School.” In The Entrepreneurial University: Public Engagements, Intersecting Impacts, edited by Y. Taylor, 82–104. Basingstoke: Palgrave Macmillan.[Crossref] , [Google Scholar]) ‘fit’ with queer-identifying religious youth, the article explores how educational experiences are narrated and made sense of as ‘progressive’. Educational transitions allow (some) sexual-religious subjects to negotiate identities more freely, albeit with ongoing constraints. Yet perceptions of what, where and who is deemed ‘progressive’ and ‘backwards’ with regard to sexuality and religion need to be met with caution, where the ‘university experience’ can shape and shake sexual-religious identity.

Global Social Responsibility: Developing a Scale for Senior High School Students in Japan

This research was conducted with the aim of clarifying a concept of “global social responsibility.” A total sample of 395 senior high school students in Japan responded to a pool of items mostly adapted from a scale developed by Starrett (1996) and provided additional data concerning their social experiences. The data were used in the development of a Japanese version of the Global Social Responsibility (GSR) scale. It was found that “global altruism,” “active involvement with society,” and “understanding of interdependence” constituted a construct of global social responsibility. It was also found that females, those who discussed social problems with their family, those who revealed a high awareness of responsibility and those who had multiple experiences of volunteer activities for community service showed high GSR scores. The scale provides both an awareness of the concept and a measure for determining levels of global social responsibility. Counseling professionals are encouraged to consider their roles from a global and social perspective, with the notion of responsibility being seen as central to the concepts of freedom and personal development.
