Abstract

The incidence of orthopedic problems was examined in 5, 582 men and women who attended the Cooper Clinic in Dallas, Texas between 1974 and 1982. The effects of age, physical activity, physical fitness, and body mass index (EMI) on the occurrence of these problems were examined using a proportional hazards approach. The expected risk of orthopedic problems per person-year was 0.045 for men and 0.046 for women. For men, physical fitness, BMI, and physical activity were associated with orthopedic problems, while for women, physical activity was the main predictor. Age was not a factor for either gender. The effect of change in physical fitness, physical activity, and BMI was examined in a subset of 2, 325 persons with more than one visit to the clinic. For women, physical activity and a decrease in BMI were associated with orthopedic problems, while for men none of those factors were significant. Again, age was not a factor in either group. The absence of any age effect on the occurrence of problems suggests that with regard to orthopedic problems, moderate amounts of physical activity in generally healthy persons may be recommended without special consideration as to age.  相似文献   

Adjusting athletes' body mass index to better reflect adiposity in epidemiological research

Abstract

The aim of the present study was to identify when body mass index (BMI) is unlikely to be a valid measure of adiposity in athletic populations and to propose a simple adjustment that will allow the BMI of athletes to reflect the adiposity normally associated with non-athletic populations. Using data from three previously published studies containing 236 athletes from seven sports and 293 age-matched controls, the association between adiposity (sum of 4 skinfold thicknesses, in millimetres) and BMI was explored using correlation, linear regression, and analysis of covariance (ANCOVA). As anticipated, there were strong positive correlations (r = 0.83 for both men and women) and slope parameters between adiposity and BMI in age-matched controls from Study 1 (all P < 0.001). The standard of sport participation reduced these associations. Of the correlations and linear-regression slope parameters between adiposity and BMI in the sports from Studies 2 and 3, although still positive in most groups, less than half of the correlations and slope parameters were statistically significant. When data from the three studies were combined, the ANCOVA identified that the BMI slope parameter of controls (5.81 mm · (kg · m^?2)^?1) was greater than the BMI slope parameter for sports (2.62 mm · (kg · m^?2)^?1) and middle-distance runners (0.94 mm · (kg · m^?2)^?1) (P < 0.001). Based on these contrasting associations, we calculated how the BMI of athletes can be adjusted to reflect the same adiposity associated with age-matched controls. This simple adjustment allows the BMI of athletes and non-athletes to be used with greater confidence when investigating the effect of BMI as a risk factor in epidemiological research.  相似文献   

Middle School Children's Responses to Enid Blyton in ‘The Bradford Book Flood Experiment’     

Jennie Ingham 《Journal of Research in Reading》1982,5(1):43-56

During‘The Bradford Book Flood Experiment’(1976–80), a longitudinal record was kept of the reading of one year-group of children in each of four middle schools in predominantly working-class areas. The children's choices of, and responses to, books were recorded on reading record forms, questionnaires which were completed by the children each time they read a book. Subsequently, it was possible to isolate responses to books written by Enid Blyton and compare responses to these books with responses to all the other authors together (i.e., to an‘average’other author). The chi-square test of significance was applied throughout. It was found that children responded more favourably to Enid Blyton in response to every question, the differences being statistically significant in every instance. Children's reasons for choice of books by Enid Blyton are quoted and categorized. An attempt is made to analyse the reasons for Enid Blyton's popularity.  相似文献   

Engaging students as digital citizens     

Lia Blaj-Ward  Kim Winter 《高等教育研究与发展》2019,38(5):879-892

ABSTRACT

Learning and teaching on physical university campuses have been enhanced by digital technology both in formally scheduled learning and teaching events and in the less formal spaces in which the higher education experience unfolds. The digital skills and know-how with which students arrive at university will arguably develop throughout the academic journey, though the extent to which they will underpin students’ growth into digital citizens, that is, confident and competent participants in a broader range of digitally enhanced social and professional communities, is likely to vary. The present article is the outcome of a research project which explored how students experience learning, teaching and communicating through digital technologies on a range of undergraduate courses at a UK university. Focus groups with fifty-five students in different years of study across twenty-three undergraduate courses revealed a nuanced understanding of the notion of ‘digital native’, yet a lack of readiness to link participation in digital spaces to digital citizenship and to articulate attributes of an effective participant in digital communities. The focus groups highlighted inconsistent alignment between personal, academic and professional digital spaces. They clearly signalled a need to explore further the commonalities and points of intersection between the three, moving beyond a skills mindset, and paying particular attention to the way in which participants in higher education construct and take up virtual identities, how they negotiate access to digital environments, the degree of control they are able and ready to exercise over digital spaces, and the contribution that universities can make to facilitate the complex developmental journeys towards digital citizenship.  相似文献   

An Update from the TRANSFER Working Group     

Elizabeth L. Winter 《期刊图书馆员》2013,64(3-4):439-445

TRANSFER is an initiative of the UK Serials Group (UKSG) that seeks to address the issues that can arise when journals change publishers. The TRANSFER Code of Practice, first released in 2008, has made some important strides in improving the process by which journals transfer from one publisher to another. There is still much work to be done, and the TRANSFER Working Group is committed to continuing to develop and disseminate procedures and policies surrounding the transfer of journals between publishers so that the annual movement of journals causes less disruption for all parties involved.  相似文献   

Partners in Collaborative Cataloging: The U.S. Government Printing Office and the University of Montana

Collaboration is a necessity in the current library environment where time, money, and resources are limited. This is particularly noticeable for institutions housing federal government documents. In addition to keeping up with the influx of current publications, federal depository libraries must address historical documents for which bibliographic records are not readily available. This report discusses how the United States Government Printing Office and the University of Montana Maureen and Mike Mansfield Library are working together to increase access to pre-1976 United States Forest Service publications and gray literature within the same subject area.  相似文献   

Predicting Employee Turnover from Friendship Networks     

Thomas Hugh Feeley  Jennie Hwang  George A. Barnett 《Journal of Applied Communication Research》2013,41(1):56-73

Employees (n=40) at a fast-food restaurant were surveyed about characteristics of their position and their level of satisfaction. Employees were then asked to report with whom they regularly communicated inside and outside the workplace and to indicate how close they were to employees with whom they were linked. Employee turnover was measured after three months had elapsed. A goal of the research was to replicate a model of employee turnover that predicts employees more central in their social network to be less likely to leave, and to test a social support explanation of the centrality model. The results indicated that employees who reported a greater number of out-degree links with friends were less likely to leave. The number of in-degree links with friends did not significantly predict turnover, and neither did network links with peers. Friendship prestige, measured by the number of in-degree links, was strongly correlated with relational closeness and amount of time spent with employees outside the workplace.  相似文献
