高水平乒乓球运动员有力臂最大等长收缩力的评估     

Francisco Pradas　Carlos de Teresa　Maricarmen Vargas　Rafael Herrero 《体育科研》2005,26(3):86-89

乒乓球是使用单侧上肢的一项运动,其特征是要进行重复多次高速且具爆发力的动作,无氧乳酸酵解代谢能力占有重要作用.研究对象与方法男女高水平乒乓球运动员(n=31).采用Takei5101握力计测量单侧上肢有力型和非单侧上肢有力型运动员的上肢最大等长收缩力.18名男运动员(平均年龄23.5±5.4岁)和13名女运动员(平均年龄21.3±3.3岁)均为西班牙乒乓球协会的国家联盟成员.采用SPSS v12.0 for windows和Excel v10.2软件包进行数据统计分析.研究结果发现无论男女运动员单侧上肢有力型的最大等长收缩力均高于非单侧上肢有力型,而左势手女运动员与右势手女运动员相比、右势手男运动员与左势手男运动员相比,单侧上肢有力型的最大等长收缩力均高于非单侧上肢有力型.研究还发现进攻型运动员与防守型运动员相比,单侧上肢有力型的最大等长收缩力高于非单侧上肢有力型.分析与讨论无论男女,单侧上肢有力型运动员手握力高于非单侧上肢有力型运动员.男性运动员比女性运动员的等长收缩力高,一个可以解释的事实是男性有更高的睾酮水平.肌肉力量不平衡可能发展成为脊柱侧弯姿态,这应该通过适当的力量和柔韧性训练来避免,以防止将来的运动损伤和运动成绩的下降.  相似文献   

Special collections in the classroom: embedding special collections in an undergraduate history writing class     

Teresa Gray 《Public Services Quarterly》2020,16(2):139-145

Abstract

This article describes a 12-year collaboration between a special collections librarian and history faculty for an undergraduate history writing course at Vanderbilt University. Originally taught as a one-shot session, the final 9 years of the course embedded the class into Special Collections for 10 weeks of primary source research. This article describes the evolution of the course from a one-shot session to full embedding, the mechanics involved in managing the sessions in Special Collections, student support considerations, and tips for other librarians offering such sessions.  相似文献

Implementing Criterion-referenced Assessment Within a Multi-disciplinary University Department     

Teresa Carlson  Doune MacDonald  Trish Gorely  Stephanie Hanrahan  Robin Burgess-Limerick 《高等教育研究与发展》2000,19(1):103-116

This paper is concerned with the reconstruction, at the departmental level, of a university assessment policy that required a shift from norm-referenced assessment to criterion-referenced assessment (CRA). As such, it provides an account of a change process driven by a centralised policy imperative and yet implemented and driven also from a bottom-up process. A wide range of data was gathered using action research methods. Individual and focus group interviews were conducted with staff and students, participant journals were kept and successive drafts of criteria and standards, and samples of students' responses were collected. The data suggested that a top-down policy can be successfully combined with a departmental-driven process, if financial and time considerations are addressed and a collaborative process amongst staff is sustained. The use of action learning, as a tool for change, appeared to assist participants to begin to own a top-down policy.  相似文献   

Predictive and concurrent relations between literacy skills in Grades 1 and 3: A longitudinal study of Italian children     

Marta Desimoni  Teresa Gloria Scalisi  Margherita Orsolini 《Learning and Instruction》2012,22(5):340-353

A sample of 170 Italian children was assessed for reading accuracy, reading speed, text comprehension and spelling in Grades 1 and 3 in order to investigate the concurrent and longitudinal relationships among literacy skills. Main results from multivariate analyses (regression, discriminant and path analyses) indicated that reading speed was the best predictor of later literacy and that spelling was the most stable measure and influenced text comprehension and reading speed. An asymmetry was also observed in the longitudinal relationship between reading and spelling errors, with reading errors predicting later spelling errors and a non-significant result in the opposite direction.  相似文献   

A feminist posthumanist political ecology of education for theorizing human-animal relations/relationships     

Teresa Lloro-Bidart 《Environmental Education Research》2017,23(1):111-130

This paper contributes to a nascent conversation in environmental education (EE) research by using ethnographic data and extant theory to develop a feminist posthumanist political ecology of education for theorizing human–animal relations/relationships. Specifically, I (1) engage feminist methodologies and theories; (2) give epistemological and theoretical attention to nonhuman animals; and (3) address the field of EE’s minimal engagement with the interdisciplinary research agenda of political ecology. The paper begins with a literature review examining how feminist and/or posthumanist scholars have theorized human–animal (or human–nature) relations/relationships. Next, I outline the conceptual frameworks guiding the analyses of ethnographic data I collected at Long Beach, California’s Aquarium of the Pacific and follow with a brief overview of the study. I conclude by outlining the major tenets of this article’s conceptual framework, which contributes to a growing conversation in EE regarding human–animal relations/relationships and lays the groundwork for other political ecologies of education.  相似文献   

Neoliberal and disciplinary environmentality and ‘sustainable seafood’ consumption: storying environmentally responsible action     

Teresa Lloro-Bidart 《Environmental Education Research》2017,23(8):1182-1199

This article invokes a neoliberal and disciplinary governmentality lens in a political ecology of education framework to analyze educational programming at Long Beach, California’s Aquarium of the Pacific. I begin by briefly describing governmentality as Foucault and neo-Foucauldian scholars have theorized the concept, followed by a discussion of the emergence of green governmentality and environmentality in political ecology. Next, I invoke a political ecology of education framework informed by neoliberal and disciplinary environmentality to analyze institutional and teaching practice at the Aquarium. In this analysis, I demonstrate how the institution’s funding structure, placement within the entertainment markets of the southern California area, and commitment to ocean conservation education all influence how the Aquarium conceptualizes itself and its work. I focus on the case of the Blue Cavern Show and the Seafood for the Future program, which work in tandem to define a problem (declining fish stocks; possible seafood shortages) and then structure a neoliberal solution through the market (sustainable seafood consumption). I conclude by discussing the implications of this research for environmental education, which include unpacking how neoliberalism impacts teaching practice, especially as it relates to notions of framing environmentally responsible action.  相似文献   

Hacking agency: Apps,autism, and neurodiversity     

Anne Teresa Demo 《Quarterly Journal of Speech》2017,103(3):277-300

This essay examines the complex relationship between agency and technology. I compare autism apps developed by Samsung and Toca Boca and show that while app marketing retains a human-centered notion of agency, user–app interactions distribute agency through a constellation of human and nonhuman actors. The divergence between marketing and use, as well as critiques about agency and technology within disability studies, motivates my argument for hacking agency. Whether in computer or knowledge networks, hacking is a critical process that exploits information silos for particular ends. In this essay, I seek to broaden notions of rhetorical capacity and challenge narrow approaches to intentionality so as to facilitate the attribution of agency across the neurological spectrum.  相似文献   

Not a one-shot deal: Generative professional development among experienced teachers   总被引：1，自引：0，他引：1  

Amy Seely Flint  Karla Zisook  Teresa R. Fisher 《Teaching and Teacher Education》2011,27(8):1163-1169

This study examines two experienced teachers’ transformations and sense of agency as they implemented a writer’s workshop curriculum with multi-lingual third grade students. Multiple lines of inquiry guide the study including communities of practice (Lave & Wenger, 1991), teacher identities in figured worlds (Holland, Lachicotte, Skinner, & Cain, 1998), and the ethic of care (Noddings, 1984/2003). A constant comparative method was used to analyze classroom observation notes, interviews and debriefing sessions (Glaser & Strauss, 1967). Findings indicate that teachers transformed their pedagogical practices around writing, and at the same time reconsidered what it may mean to become renewed professionals.  相似文献   

Understanding user needs for citation management program support     

Teresa U. Berry  Steven D. Milewski  Manda C. Sexton  Allison L. Sharp 《Public Services Quarterly》2020,16(2):71-82

Abstract

Citation management programs are tools used to organize references and to create citations and bibliographies. Libraries are often the central point for providing training and support in using these tools. To determine how we could improve our support and training services, we surveyed users to determine what software in being used, why they chose that particular program, what features are important, and how they use citation management programs to collaborate. Results indicate that users chose a particular program because it was freely available or recommended to them by others and that they thought that importing references and creating citations were important features. We also found a majority of respondents used citation management programs to collaborate and turned to the library for training and support.  相似文献
