The purposes of this study were to describe and compare the specific physical activity choices and sedentary pursuits of African American and Caucasian American girls. Participants were 1,124 African American and 1,068 Caucasian American eighth-grade students from 31 middle schools. The 3-Day Physical Activity Recall (3DPAR) was used to measure participation in physical activities and sedentary pursuits. The most frequently reported physical activities were walking, basketball, jogging or running, bicycling, and social dancing. Differences between groups were found in 11 physical activities and 3 sedentary pursuits. Participation rates were higher in African American girls (p < or = .001) for social dancing, basketball, watching television, and church attendance but lower in calisthenics, ballet and other dance, jogging or running, rollerblading, soccer, softball or baseball, using an exercise machine, swimming, and homework. Cultural differences of groups should be considered when planning interventions to promote physical activity. 相似文献
This article reports on the evaluation of the first year of a project, which utilized learning sets to support librarians undergoing the accreditation process, in the health libraries in the West Midlands region of the NHS. The West Midlands Health region is divided up into education consortia patches. Each group of patch librarians was allocated a local accreditation facilitator. The groups met regularly to discuss problems and progress relating to their library’s accreditation. The results of the evaluation suggest that this is a valuable approach to use. The recommendations state that regular, frequent meetings are needed. Extra training and guidance would help the facilitators to be more effective in their role. 相似文献
This paper reports on a longitudinal interpretive case study of the transtion from preservice to inservice science teaching.
We describe four sets of overlapping worlds that provide vantagepoints for the study. Three sets describe the experiences
of Katie, the participating teacher. These are the world of the person who is good at science and the world of the person
who is not, the world of the student teacher and the world of the novice teacher, and the world of the primary science classroom
and the world of the primary classroom during other subjects. The final set describes our development as researchers during
this period—the world of the specialist science teacher and the world of the generalist teacher. In our analysis of the transition
experience, we employ the term entryways to describe understandings and strategies that helped the teacher and ourselves to
move between contrasting perspectives. 相似文献
This article describes a collaborative research project by the institutional research group and a team of faculty members at a Canadian university. In response to an increasingly diverse mix of students, the researchers set out to develop an understanding of relationships between student characteristics, categorized as demographic differences, personal attributes and academic preparedness, and student outcomes measured by both grades and student perceptions. Significant differences were found in grades outcomes based on characteristics such as international status, secondary school grades, study habits and writing skills. However, these differences were not evident in student perceptions of course value or learning achievement. This study has important implications for university administrators (recruiting, intake assessment and student support), instructors (understanding of diversity characteristics and how students perceive learning experience) and for students, who can be given an opportunity to better understand how their own personal characteristics might affect their learning experiences and outcomes.
Previous studies on the kinematics of the golf swing have mainly focused on group analysis of male golfers of a wide ability range. In the present study, we investigated gross body kinematics using a novel method of analysis for golf research for a group of low handicap female golfers to provide an understanding of their swing mechanics in relation to performance. Data were collected for the drive swings of 16 golfers using a 12-camera three-dimensional motion capture system and a stereoscopic launch monitor. Analysis of covariance identified three covariates (increased pelvis-thorax differential at the top of the backswing, increased pelvis translation during the backswing, and a decrease in absolute backswing time) as determinants of the variance in clubhead speed (adjusted r (2) = 0.965, P < 0.05). A significant correlation was found between left-hand grip strength and clubhead speed (r = 0.54, P < 0.05) and between handicap and clubhead speed (r = -0.612, P < 0.05). Flexibility measures showed some correlation with clubhead speed; both sitting flexibility tests gave positive correlations (clockwise: r = 0.522, P < 0.05; counterclockwise: r = 0.711, P < 0.01). The results suggest that there is no common driver swing technique for optimal performance in low handicap female golfers, and therefore consideration should be given to individual swing characteristics in future studies. 相似文献
This special issue of Archival Science examines the orientations, paradoxes, and tensions evident in the ethical struggles over the construction of the past and the degree to which archival agency can intercede in supporting a broadly drawn historical justice that also engages contemporary issues. Inspired and framed by a May 2008 conference hosted by School of Information and Labadie Collection, University of Michigan, Ann Arbor, the following essays offer case study examinations of how archival institutions and archivists contribute to societal memory systems through both their action and inaction, especially in regard to societal struggles over the meanings to be derived from the past. 相似文献
