The aim of this study was to determine the influence of barefoot running on foot-strike patterns, eversion–inversion, running speed and vertical foot rotation in endurance runners. Eighty healthy recreational runners (age = 34.11 ± 12.95 years old, body mass index = 22.56 ± 2.65 kg · m^?2) performed trials in shod/unshod running conditions on a treadmill at comfortable and competitive self-selected speeds. Data were collected by systematic observation of lateral and back recordings at 240 Hz. McNemar’s test indicated significant differences between shod/unshod conditions and foot strike at comfortable and competitive speeds (P < 0.001). Speed was related to vertical foot rotation type for shod (P < 0.01) and unshod conditions (P < 0.05). Significant differences were found between shod/unshod conditions in foot rotation at comfortable running speeds (P < 0.001) and competitive running speeds (P < 0.01). No significant difference was found in inversion or eversion (P ≥ 0.05). In conclusion, the results suggest that running kinematics, in terms of foot-strike patterns and vertical foot rotation, differ between shod/unshod conditions, while the inversion or eversion degree remains unchanged.  相似文献   

Crowdsourcing as an Approach to Customer Relationship Building in Academic Libraries     

Lisa A. Ellis  Aisha Peña 《College & Undergraduate Libraries》2015,22(3-4):273-295

Library initiatives to first-year students not only present an opportunity to offer information literacy instruction for student advancement, but they also serve a key marketing function by communicating the library's ongoing value and building customer relationships. Library orientation tours are an example of how to effectively market to first-year students. Combining peer-to-peer learning and user-generated content via social media known as crowdsourcing, Newman Library sponsored a contest challenging first-year students to create a video sharing a useful library tip. The contributions and benefits of this cocreation approach to fostering relationships are examined, and the implications to strengthening other library-user bonds are explored.  相似文献

Solving Problems in Genetics II: Conceptual restructuring     

Teresa Ibáñez Orcajo 《International Journal of Science Education》2013,35(12):1495-1519

This paper presents the results of part of an investigation carried out with fourth‐level Spanish secondary education students (15 years old), in which we implemented a teaching unit based on problem‐solving methodology as an investigation to teach genetics and human inheritance curricular contents. By solving open problems, the students experienced a conceptual restructuring that stayed with them over time and involved the following specific theories: the location of hereditary information, the transmission of hereditary information, and the appearance of new characteristic. The learning connections between these specific theories were also studied. Furthermore, these results were compared with a control group that worked with closed problems, the usual approach to genetics teaching in Spanish classrooms. Consequently, we were able to verify that our methodology results in better learning.  相似文献   

Assessing effectiveness of nurture groups in Northern Scotland     

Isabel Shaver  Kirstie McClatchey 《Support for Learning》2013,28(3):97-102

The aim of this small‐scale study was to assess the effectiveness of nurture groups in Northern Scotland. Data were collected from children (N = 19) and staff (N = 5) from three nurture groups. Pre‐ and post‐nurture group Boxall Profile information was also assessed for 33 children across two of the nurture groups. Analysis of the Boxall Profiles found that nurture group children had made significant gains. The majority of children reported that they feel happy and enjoy attending the nurture groups. Nurture group staff reported improvements in the children, and that parents are positive about the nurture groups. However, staff did report a number of challenges that the nurture group face. Overall, this study contributes to the evidence that nurture groups can be an effective intervention for improving social, emotional and behavioural outcomes for children.  相似文献

Goal orientation profile differences on perceived motivational climate, perceived peer relationships, and motivation-related responses of youth athletes     

Smith AL  Balaguer I  Duda JL 《Journal of sports sciences》2006,24(12):1315-1327

The aims of this study were twofold: (a) to determine if dispositional achievement goal orientation profiles that are reported in the literature would be observed in a sample of youth athletes, and (b) to examine potential achievement goal orientation profile differences on perceptions of the motivational climate, perceptions of peer relationships, and motivation-related responses. Male soccer players (n=223) aged 9-12 years (mean=10.9, s=0.6) completed a multi-section questionnaire containing assessments of dispositional goal (task, ego) orientations, the perceived task- and ego-involving features of the motivational climate, perceived peer acceptance and friendship quality (positive friendship quality, conflict), perceived ability, soccer enjoyment, and satisfaction with one's performance and the team. Four profiles were observed that closely matched those observed by Hodge and Petlichkoff (2000), though in the present study a lower proportion of participants exhibited achievement goal profiles consisting of relatively high ego orientation. Achievement goal profile differences were found for all variables except positive friendship quality, with a general trend for those reporting relatively lower task goal orientation to exhibit less adaptive responses. Overall, the findings support achievement goal frameworks (e.g. Nicholls, 1989) and suggest that further examination of dispositional achievement goals may afford a deeper understanding of social relationships and motivational processes in youth sport.  相似文献
