ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).  相似文献

Exploring Developmental Appropriateness of Multitouch Tables in Prekindergarten: A Video Analysis     

Jennifer Ward  Stephanie Branson  Megan D. Cross  Ilene R. Berson 《Journal of Research on Technology in Education》2016,48(3):227-238

This study explored how developmentally appropriate practices influenced the affordances of a multitouch surface in an early childhood classroom. Children, ages 4 to 5 years old, were videotaped while engaged in a storymaking application on a multitouch table. As a result of the study, we found that some challenges with the functionality undermined children's autonomous control. The researchers observed numerous instances of issues with control of the medium, including height of the table, sensitivity to multiple types of touch, and limited instructions and prompts. Implications for future research and practice are discussed.  相似文献

Eating Attitudes and Behaviors Among Female College Students     

Katherine D. Veazey Morris  Gilbert R. Parra  Sarah R. S. Stender 《Journal of College Counseling》2011,14(1):21-33

The authors assessed the influences of several risk factors—self‐esteem, history of unwanted sexual contact (USC), depression, and sorority membership—on eating‐related and weight‐related attitudes and behaviors. Findings provide support for the roles of self‐esteem, depression, and USC on restricting attitudes. According to the authors' model, these independent variables predicted restricting attitudes that then predicted restricting behaviors. Implications for preventive interventions and the study's limitations are discussed.  相似文献   

Distance education copyright,intellectual property,and antitrust concerns

Abstract

An empirical examination of accredited American higher education institutions was conducted to obtain baseline data regarding distance education copyright, intellectual property, and antitrust concerns. Additionally, a multiple‐case study involving ten of the top thirty accredited distance education institutions in America was conducted. Policy approaches were examined for all institutions, and differences were discussed between public and private institutions as well as between the following Carnegie Classification institutions: Research I and II, Doctorate I and II, and Master's I and II. Data indicated that, out of the schools surveyed, 22% of the institutions in these Carnegie Classification categories published copyright and intellectual property policies on their institution's Web site. In the case study, it was found that 90% of the institutions centrally controlled their distance education program administration as well as the copyright and intellectual property policies related to it.  相似文献   

The Effect of a National Initiative on Exam Results     

P.B. Tymms  C.T. Fitz‐Gibbon  J.J.C. McCabe  R.D. Hazelwood 《School Effectiveness & School Improvement》2013,24(4):281-298

ABSTRACT

This paper considers the examination results of TVEI and non TVEI pupils in the database established at the University of Newcastle in 1985‐87. The pupils took national exams in the summer of 1987, when they were about 16 years old. Their average grades (Exam Means) and their accumulated grades (Exam Totals) were considered separately.

The Exam Mean and Exam Total scores were generally worse for TVEI than non TVEI pupils, even when pupils with the same ability test scores and aspirational scores were compared. However, it is possible that non TVEI factors caused the discrepancy in results and it is these factors which are the subjects of this paper.

The paper considers firstly whether the differences are an artefact of regression analysis. Secondly, the data are considered using various multilevel models. Both analyses suggest that there was no TVEI effect on the Exam Mean score and a negative TVEI effect on the Exam Total. Various explanations for these findings, concerning internal school allocational and curriculum policies, are considered and discussed.  相似文献

An intervention in the Halliwick Method procedures (swimming) for a group of individuals with Downs syndrome

The purpose of this study was to intervene in the process of the Halliwick Method (swimming), in order to improve the method, or some of its aspects, for a sample of 14 individuals with Downs syndrome (aged six to 21 years), using both an individualized educational setting approach and a differentiation of the elements of the Halliwick Method. The pre-intervention phase included medical examination, IQ, measurement of the behaviour according to the Rutter Scale and a Test of Physical Performance for each subject. Next, the subjects were assigned to seven pairs of case studies, where each individual following a Halliwick Methods swimming programme was paired with an individual following a modified swimming programme based on the same method, on physical health variables, IQ, behaviour and motor abilities. The duration of each swimming programme was 24 weeks for each individual, at a frequency of once per week, for 40 minutes. In the light of the findings of this study, further recommendations for the improvement of Halliwick Method procedures were made, common factors that affected the performance of each individual were identified and their relation with performance was explored.  相似文献
