The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 years, n = 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Groundwork Combat Time and Pause Time. Analysis of variance (ANOVA) one-way and the Tukey test, as well as the Kruskal-Wallis test and Mann-Whitney (for non-parametric data), were conducted, using P < 0.05 as significance level. The results showed that all analysed groups obtained a median of 7 (first quantile - 3, third quantile - 12) sequences of combat/pause cycles. In total time of combat, the result was: for Total Combat Time, Standing Combat Time and Gripping Time: Pre-Juvenile and Senior were significantly longer than Juvenile and Junior. Considering Displacement Without Contact, Junior was significantly longer than all other age groups. For Groundwork Combat Time, Senior was significantly longer than all other age groups and Pre-Juvenile was longer than Junior. These results can be used to improve the physiological performance in intermittent practices, as well as technical-tactical training during judo sessions.  相似文献   

Doulas as community health workers: lessons learned from a volunteer program     

Kane Low L  Moffat A  Brennan P 《The Journal of perinatal education》2006,15(3):25-33

Doulas, women who primarily provide social support during childbirth, have been associated with a number of positive health outcomes. Because the primary model of practice for doulas is a fee-for-service model in which families privately hire a doula, many expectant women who could benefit from doula support are unable to access the service. The Doulas Care program, located in Ann Arbor, Michigan, represents one model in which doulas provide services without charge. As a result of their extended role in the community, doulas who work with the Doulas Care program have unique educational needs. Through the use of focus groups with the program's volunteer doulas, educational needs related to overcoming barriers to being a doula working in the community were identified. Recommendations for education and training are made to improve the support doulas offer as community health outreach workers.  相似文献   

Redefining Successful Interpretation in Art Museums     

Daryl Fischer  Lisa Levinson 《Curator: The Museum Journal》2010,53(3):299-323

Abstract This article aims to capture the spirit and content of a lively exchange among museum staff members at the Denver Art Museum. It began as a conference call and continued as an online dialogue about how definitions of success have evolved with advances in technology and changing expectations of visitors. Together we explored how DAM staff encourage more active participation in the museum and the creative tension that ensues between visitor co‐creation and institutional control. Woven throughout this conversation are examples that demonstrate the need to move fluidly between high tech and low tech interpretives, onsite and online experiences, and the impact of environments that break down museum stereotypes. It is our hope that this discussion will spark similar dialogues among colleagues in individual institutions and in the profession at large.

Perceptions of typically developing children in India about their siblings with disabilities     

Ankita Bhattashali  Michaelene M. Ostrosky  Lisa Monda-Amaya 《International Journal of Inclusive Education》2013,17(12):1257-1271

ABSTRACT

In India, people with disabilities often struggle to access various opportunities and resources. As a result of perceptions within the Indian culture around disabilities, families may face social, financial, and emotional difficulties. Within the family, a child with a disability may lead to strained relationships, particularly with siblings. Often siblings have little knowledge about disabilities and may feel ostracised. The purpose of this exploratory study was to examine the knowledge and attitudes of 12 Indian children regarding their siblings with disabilities, including their perceptions about disabilities against the backdrop of societal attitudes. Participants were interviewed to understand their knowledge of their siblings’ disabilities, to examine their sibling relationships, and to assess how school and society influenced their perceptions about disabilities. Results from this study can help family members understand how disability shapes relationships between children. The findings also provide key stakeholders with information that might help them better support families.  相似文献

Intentionally designed thinking and experience spaces: What we learned at summer camp     

Tove I. Dahl  Lisa Sethre-Hofstad  Gavriel Salomon 《Learning Environments Research》2013,16(1):91-112

How do young people experience camp, and how might that experience help us expand our understanding of what is possible in non-formal learning environments? In-depth interviews consisting of forced-choice and open-ended questions were conducted with 59 Concordia Language Villages residential camp participants who partake in a linguistically and culturally enriched grand simulation. This study focused on (1) quantitative assessments of their sense of safety and belonging, and (2) open-ended questions about the nature of the camp environment in general and as a learning place. From the qualitative data, we distilled participants’ sense of camp as a learning place by analysing their responses in terms of theoretically-driven categories of thinking space qualities and data-driven categories of experience space qualities. As a thinking space, participants described the camp environment as a safe space characterized by support for thinking and development, room for identity-supportive interactions, room to experiment, and a place with mentoring adults and a second-home feeling. As an experience space, they emphasized the centrality of the program’s daily activities (particularly simulations), the qualities of the people around them (diverse and community-focused), the physical setting of the program (particularly its aesthetics) and the instructional methods used (particularly language and cultural immersion). The relationship of these findings to our understanding of the nature of the thinking and experience spaces as program-specific and program-general phenomena is discussed.  相似文献   

Transformative conversations about sexualities pedagogy and the experience of sexual knowing     

Lisa Trimble 《Sex education》2013,13(1):51-64

One of the hallmarks of sex education traditionally has been its Cartesian endorsement of mind/body dualism; we have preferred to equate ‘self’ as synonymous with ‘mind’, and have invested heavily in believing in the valence of rationality‐based sexualities education. We generally do not consider the way ‘self’ negotiates, interprets and relates to sexual knowledge in all of our complexity, including our messy, embodied and emotional lives. In this paper I address what I think are several much‐needed conversations for a holistic pedagogy of sexualities to incorporate, including the falseness of the mind/body split, reconsidering what counts as sexual knowledge, the role of the performative in communicating our sexual knowing, and the importance of considering affect in learning about sexualities. The second part of the paper examines pedagogical considerations currently absent in dialogues of sexualities education, such as incorporating transformational learning strategies in teaching sexualities, and what it means to educate toward being a sexual citizen. Finally, I will outline how discussions of epistephenomenology (our relationship to and how we experience knowledge) can contribute to moving toward a vision of a critical, cultural sexualities education.  相似文献   

Predicting Robust Learning With the Visual Form of the Moment-by-Moment Learning Curve     

Ryan S. Baker  Arnon Hershkovitz  Lisa M. Rossi  Adam B. Goldstein  Sujith M. Gowda 《学习科学杂志》2013,22(4):639-666

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker, Goldstein, & Heffernan, 2010 Baker, R. S. J. d., Goldstein, A. B. and Heffernan, N. T. 2010. “Detecting the moment of learning”. In Proceedings of the 10th Annual Conference on Intelligent Tutoring Systems 25–34. In V. Aleven, J. Kay, & J. Mostow (Eds.),pp.Heidelberg, Germany: Springer.[Crossref] , [Google Scholar], 2011). Two coders labeled data from students who used an intelligent tutoring system for college genetics. They coded in terms of 7 forms that the moment-by-moment learning curve can take. These labels are correlated to test data on the robustness of students’ learning. We find that different visual forms are correlated with very different learning outcomes. This work suggests that analysis of moment-by-moment learning curves may be able to shed light on the implications of students’ different patterns of learning over time.  相似文献   

The Level of Decision-Making,Perceived Influence,and Perceived Satisfaction of Faculty and Their Impact on Student Retention in Community Colleges     

Lisa Miller 《Community College Journal of Research & Practice》2013,37(7):515-529

ABSTRACT

This study expanded on previous models that looked primarily at student and support factors related to student retention and examined other stakeholder group functions not previously reviewed in relation to student retention. The research question assumed that greater faculty participation in campus decision-making and faculty satisfaction would have been associated with a higher campus student retention rate. The non-experimental retrospective design examined the unanalyzed 2007 community college (CC) Changing Academic Profession (CAP) survey in relation to campus retention rates. The CAP captured faculty perceptions of whether faculty or non-faculty entities were the primary influence on decisions regarding academic matters, as well as a rating of faculty satisfaction. Analysis indicated that CC faculty rated their participation in campus decision-making versus non-faculty entities similarly to the ratings of faculty who had completed the CAP at four-year institutions. When compared with the 2007 retention rate per campus, only faculty job satisfaction was statistically significantly positively associated with student retention. Recommendations for future research include continuing to look at retention as an outcome of a multi-factorial model involving all campus stakeholders, and more research with retention as the outcome.  相似文献
