The effects of running with or without shoes on injury prevention have been extensively studied, and several investigations have assessed biomechanical differences between them. However, findings are not consensual and further insights on biomechanical load associated with differently shod or barefoot conditions may be needed. This study aimed to observe if habitually shod marathon runners show acute alterations when running barefoot or with minimalist shoes, and to determine whether the running kinematical adaptations of wearing minimalist shoes were similar to barefoot running. Twelve male marathon runners ran on the treadmill at their average marathon pace in different footwear conditions: habitual running shoes, minimalist shoes, and barefoot. High-resolution infrared cameras and visual 3D software were used to assess kinematic data. The following parameters were studied: foot strike angle, cycle time, stance time, normalized stride length, hip, knee, and ankle angular position at initial contact, and their respective range-of-motion (ROM) during stance phase. Contrary to the expectations, it was found that highly trained habitually shod elite marathon runners changed their lower limb kinematic pattern both when running barefoot or wearing minimalist shoes. Minimalist shoes showed a trend towards intermediate biomechanical effects between running with and without shoes. 相似文献
ABSTRACTSchool-based sports and physical education play an important role in the development of youth (Jones, Edwards, et al., 2017), but participation in athletics is unequal for lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth compared to their straight/cisgender peers [Greenspan, S. B., Griffith, C., & Murtagh, E. F. (2017). LGBTQ youths’ school athletic experiences: A 40-year content analysis in nine flagship journals. Journal of LGBT Issues in Counseling, 11(3), 190–200]. Sport cultures, generally, recreate dynamics of exclusion for marginalized youth. However, there are opportunities to transform these spaces into more inclusive and positive environments to support positive growth for all young people [Newman, T., Alvarez, A., & Kim, M. (2017). An experiential approach to sport-based positive youth development. Journal of Experiential Education, 40(3), 308–322]. Our study uses a data set of adolescents, collected as part of a community-based participatory action research project led by high school students in southeast Michigan, USA. Respondents reported their sexual and gender identities, as well as experiences in youth sport, as well as safety using sex-segregated facilities (i.e., bathrooms and locker-rooms). Using mediation models based on linear regression, we found evidence that LGBQ high school students play sports at a significantly lower rate compared to straight students, and among those who play sports, LGBTQ respondents felt significantly less safe compared to straight and cisgender students. Opposite to the LGBQ and trans youth in this study, straight/cisgender youth also reported feeling safer using all facilities. The mediation models suggest that these inequalities help to explain disparities in rates of sports participation and feelings of safety while participating. These findings have important implications for policy, practice, and future research. 相似文献
Out of considerations as to the importance of university relationships with their various stakeholders, the primary objective of this research project was to identify the perceptions of academic journal editors regarding universities. Editors were asked to provide their perceptions on: (a) the relevance of universities to academic publications; (b) the mutual influence between universities and academic journals; and (c) the participation of editors in universities. Following initial exploratory research, we applied an online questionnaire and received a total of 276 responses from editors of indexed publications, enabling analysis of their perceptions. Despite editors recognizing the influence of universities on academic and scientific communities, our findings point to universities having failed in proactively reaching out to editors, especially surprising given the vast experience held by such figures. A better relationship might serve to enhance the university image and generate new opportunities for attracting resources.
Abstract Multiculturalism is official Canadian policy. In the context of postmodernism, pluralism has taken on a sharper meaning, particularly with regard to identity. What can possibly unify a diverse nation like Canada? Does the separation of religion from public life make sense when cultural identity includes religious expression? Political unity, religious diversity, and the common search for and establishment of justice could become the essential building blocks toward an integral political unity. In particular, the celebration of religious diversity in Canada's schools could become a primary means of political unity as well as an essential means of unifying society. Five convictions are developed which help secure a new relationship among religious education, religious diversity, and political and societal unity. 相似文献
A content analysis of the journal Religious Education: An Interfaith Journal of Spirituality, Growth and Transformation was conducted for a 10-year period between 1993–2002 (Volume 88, 1–Volume 97, 4). A total of 325 articles (277 authors) were analyzed into 3 primary research directions (theoretical, qualitative, and quantitative). Author institutional affiliation, religious identity, position, geographic location, and number of contributions were also computed. Implications for the Journal and the field of religious education are discussed. 相似文献
Abstract Residential environmental education camps provide a setting that can result in beneficial changes in participants' self-esteem, interpersonal relationships, and feelings of connection with the natural world, as well as stimulating greater interest in future low-impact recreation experiences in natural areas. When students learn how ecosystems function and about environmental action strategies that contribute to their maintenance, they develop more environmentally responsible behaviors. Wolf Creek Nature Camp is an environmental education program that integrates awareness of the natural environment, knowledge of environmental concepts and issues, and action on environmental problems. The 2-week program raises campers' self-esteem; increases their interest in, and curiosity about, nature, and fosters outdoor skills. Enhanced self-esteem is a major influence on their desire to take further environmental action. 相似文献
Most outcomes assessment in higher education has focused on content knowledge or skills development; however, attitudinal change is also a legitimate focus of assessment. We use the New Ecological Paradigm (NEP) to test whether courses designed to meet the same university environmental literacy requirement changed student environmental attitudes, and whether these changes resulted from instructor and/or course-content effects. We found student environmental attitudes did change significantly but in different directions depending upon who taught the course. The ability to measure such changes adds to the discussion in the environmental education community on the desired nature of attitudinal change and of the responsibilities of higher education instructors. 相似文献
RESUMENRelacionada con la distinción piagetiana entre el pensamiento concreto y el pensamiento formal se presenta una Investigación con sujetos de 7 a 17 años acerca del desarrollo de la capacidad de comprobar y modificar hipótesis sobre problemas complejos; las dos tareas resultan difíciles para los niños y los adolescentes aunque se utilizan diferentes estrategias según la edad de los sujetos. Finalmente se efectúan unas consideraciones generales sobre la relación entre los datos obtenidos y las enseñanza de las ciencias. 相似文献
ResumenEn este articulo se plantea una discusión acerca de la teoria e investigaciones más relevantes sobre el desarrollo de la comprensión de la historia en el niño. Desde una perspectiva piagetiana se estudian los procesos cognitivos involucrados en la realización de tareas históricas. Se exponen los resultados de una investigación sobre 175 niños acerca de la comprensión de conceptos utilizados comúnmente en la enseñanza de la Historia y una segunda investigación sobre 695 niños acerca de la comprensión y uso de la noción de tiempo cronológico. Los resultados ponen de manifiesto la gran dificultad de este tipo de tareas y su evolución con la edad. 相似文献
