ABSTRACT

Full three-dimensional movements and external moments in golfers’ knees and the possible involvement in injuries have not been evaluated using motion capture at high sample frequencies. This study measured joint angles and external moments around the three anatomical axes in both knees of 10 professional golfers performing golf drives whilst standing on two force plates in a motion capture laboratory. Significant differences were found in the knee joint moments between the lead and trail limbs for the peak values and throughout all stages during the swing phase. A significantly higher net abduction moment impulse was seen in the trail limb compared with the lead limb (?0.518 vs. ?0.135 Nms.kg^?1), indicating greater loading over the whole swing, which could contribute to knee lateral compartment or anterior cruciate ligament injuries. A significant correlation (r = ?0.85) between clubhead speed at ball contact and maximum joint moment was found, with the largest correlations being found for joint moments at the top of the backswing event and at the end of the follow-through. Therefore, although knee moments can contribute to high clubhead speeds, the large moments and impulses suggest that they may also contribute to chronic knee injuries or exacerbate existing conditions.  相似文献   

Android arete: Toward a virtue ethic for computational agents     

Kari Gwen Coleman 《Ethics and Information Technology》2001,3(4):247-265

Traditional approaches to computer ethics regard computers as tools, andfocus, therefore, on the ethics of their use. Alternatively, computer ethicsmight instead be understood as a study of the ethics of computationalagents, exploring, for example, the different characteristics and behaviorsthat might benefit such an agent in accomplishing its goals. In this paper,I identify a list of characteristics of computational agents that facilitatetheir pursuit of their end, and claim that these characteristics can beunderstood as virtues within a framework of virtue ethics. This frameworkincludes four broad categories – agentive, social, environmental, and moral– each of which can be understood as a spectrum of virtues rangingbetween two extreme subcategories. Although the use of a virtue frameworkis metaphorical rather than literal, I argue that by providing a frameworkfor identifying and critiquing assumptions about what a `good' computer is,a study of android arete provides focus and direction to the developmentof future computational agents.  相似文献   

Science in Action: How Middle School Students Are Changing Their World Through STEM Service-Learning Projects     

Jane L. Newman  John Dantzler  April N. Coleman 《理论付诸实践》2015,54(1):47-54

The purpose of Science in Action (SIA) was to examine the relationship between implementing quality science, technology, engineering, and math (STEM) service-learning (SL) projects and the effect on students' academic engagement in middle school science, civic responsibility, and resilience to at-risk behaviors. The innovative project funded by the Corporation for National and Community Service (CNCS) included 6,000+ middle school at-risk students (eligible for at least 50% free or reduced-cost lunch), 126 science teachers who integrated STEM problem-based SL pedagogy into science instruction to teach students to solve real problems in schools and communities. The project involved 20 schools and communities with assistance from 120 community partners. Participants completed pre- and post-SL surveys on academic engagement, civic responsibility, and resilience; qualitative data were collected from journals, interviews, focus groups, observations, and field notes. Results highlight exemplary SL projects that demonstrated increased student academic engagement and achievement for students living in high poverty areas with potential at-risk behavior. Implications for future research and educational practices are discussed.  相似文献

Effects of self‐monitoring,token reinforcement and different back‐up reinforcers on the classroom behaviour of retardates     

Peter Coleman  Neville M. Blampied 《International Journal of Disability, Development & Education》1977,24(2):95-107

Following a baseline observation period, a class of intellectually handicapped boys were given opportunities to monitor and record their own behaviour as on‐task or off‐task. Following this self‐monitoring phase, the self‐administered check‐marks were used as tokens and exchanged for back‐up consequences, which were initially low‐value objects for consumption (possession). These were later increased in value, and finally changed to access consequences (the opportunity to play with but not possess). Self‐monitoring alone produced a significant increment in the externally assessed level of on‐task behaviour. Only when access back‐up consequences were introduced was there a further significant increment. Provision of high‐value consumption consequences was followed by a loss of accuracy in self‐monitoring, and reduction in on‐task behaviour to baseline levels. The study demonstrated the extension of a self‐control procedure to retardates, the importance of separately measuring the effect of self‐monitoring on the target behaviour, and the need for appropriate selection of back‐up consequences.  相似文献   

Leading professional learning in an Australian secondary school through school‐university partnerships     

Julianne Moss 《Asia-Pacific Journal of Teacher Education》2008,36(4):345-357

As the limitations of one‐off and disconnected professional learning programs for teachers are recognised, there is widespread interest in building learning communities and professional learning teams within schools. When considering how to build local learning communities, school and university partnerships are seen as offering rich possibilities for transformative professional action. Set in the context of the international agenda of “Education For All” (UNESCO, 2005 UNESCO. (2005). Education for all: Global monitoring project. Retrieved January 8, 2007, from http://portal.unesco.org/education/en/ev.php‐URL_ID=36004&URL_DO=DO_TOPIC&URL_SECTION=201.html (http://portal.unesco.org/education/en/ev.php-URL_ID=36004&URL_DO=DO_TOPIC&URL_SECTION=201.html)  [Google Scholar]) a model of sustained on‐going professional learning, developed in one large secondary school in Australia, is analysed. The social practices that generate action and participation for partnership members are then scrutinised for the legitimacy of school‐university partnerships and the contribution to enhancing teacher learning.  相似文献   

2014 Australian Association for Research in Education Presidential Address     

Julianne Moss 《The Australian Educational Researcher》2016,43(5):505-525

The 2014, 41st Australian Association for Research in Education (AARE) presidential address is both inspired and guided by the discursive genres of presidential addresses and the role of the president in a member association such as AARE. In the address, typically the president speaks to the members on an issue or issues that are to shape or conclude their term of office, as it is in my case. Like many of the 40 AARE presidents who have gone before me, I will embed some things that are professional, personal and political—not in the interests of advancing my research agenda, but to add “to the weave and pattern of the association’s history” (Reid 2010, p. v). Threads of my research since completing my PhD in 2000 will appear to support the broad argument. Also, I will draw on the outcomes of the 2014 Australian Research Council Discovery round (see Australian Research Council: ARC archives 2016) to encapsulate my key argument that educational research and its (ex)changes are being reshaped: in a post human digital age, the tree of knowledge is mutating. To make my argument, I will review how the thinking and doing of educational research mid-way through the second decade of the twenty-first century is constructed and ask what research endeavours might be created to make the best possible worlds for our member community and the aspirations of the association.  相似文献   

Using Early Learning Standards to Provide High-Quality Education for All Children: The Early Learning Guidelines Toolkit     

Roseanne L. Flores  Timothy W. Curby  Hardin Coleman  Kristan Melo 《理论付诸实践》2016,55(2):145-152

Today with the rise in the number of 3- to 6-year-old children enrolled in center-based early childhood programs, and a focus on program quality, it becomes imperative for educators to have a better understanding of the role research plays in establishing high-quality programs as these programs provide much of the foundation that supports early learning and development (Child Trends, 2014). Although psychology, and the role of child development research in particular, has always been integral to the field of early childhood education beginning with the seminal works of Piaget, Bronfenbrenner, Bruner, and others (Lickona,1971), the field had never fully embraced the use of research to inform practice, until the 1990s. This had been, in part, because the field of early childhood education originally viewed itself as a field of practitioners that provided for the everyday care and needs of young children, whereas it viewed child development researchers as scientists who paid little attention to the practical needs of classroom teaching (Takanishi, 1981 Takanishi, R. (1981). Early childhood education and research: The changing relationship. Theory into Practice, 20, 86–92.[Taylor & Francis Online] , [Google Scholar]). Although, today, there is no longer this ideological divide between the two areas, with the child development research being used to inform educational practice and policy (Center for the Developing Child, 2007), nevertheless there still remains a gap in the ability of educators to effectively implement evidence-based practices. Given the increased focus on providing young children with access to high-quality education, and the need for teachers to implement evidence-based practices the present paper attempts to bridge the gap by providing a brief overview of the science of early childhood development, its importance for development of early learning standards, and an overview of the Early Learning Toolkit which was developed to provide early learning educators guidance and resources to support the implementation of early learning standards within their own states as well as well across the nation. The goal of this article is to bridge theory and practice in early childhood education.  相似文献
