ABSTRACTThe aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time. 相似文献

In 2008 Meier and Conkling first tested Google Scholar's coverage of the engineering literature against citations gathered from the Compendex database. Since that time, other studies have used the same methodology and found improvement in Google Scholar's coverage. This study uses engineering dissertations from Proquest Dissertations & Theses to create a data set of citations for the comparison of fee-based databases, Compendex and Scopus, against Google Scholar. From 1950 to 2017 Google Scholar outperformed both Compendex and Scopus in discoverability of citations in nine engineering subjects. These results have implications for collection management and information literacy program planning for librarians. 相似文献

This essay reviews two recently published American books about masculinity politics—Michael Kimmel's pro-feminist Manhood in America and his edited collection The Politics of Manhood —in order to comment critically on the current debate underway in various parts of the world on 'boys' and their schooling which sees them as the 'new victims' of the educational process. 相似文献

In order to emphasize the development of skills in helping the culturally disadvantaged, graduate students were given practicum placement in a Department of Labor-financed agency which gave counseling and employment training to disadvantaged youth. Students attended staff meetings, interviewed staff members concerning the work they performed, and discussed client contacts with caseworkers, in addition to interviewing agency clients. Increased awareness of problems, broadened conceptualizations, and expansion of interpersonal skills were seen as advantages of the practicum. Limitations included some lack of goal clarity and inefficiency of time use in dealing with this clientele. 相似文献

Sexual and physical abuse history and adult sexual risk behaviors: relationships among women and potential mediators 总被引:1,自引:0,他引:1
OBJECTIVE: While research has supported associations between experiencing abuse and engaging in risky sexual behaviors during adolescence, research regarding these associations among adult women is much more equivocal. In addition, few studies have attempted to identify potential pathways from abuse experiences to sexual risk behaviors. The current study examined the associations between a history of physical or sexual abuse and recent sexual risk behaviors among adult women. Additionally, this study evaluated binge drinking and depressive symptomatology as potential mediators of any relationships between abuse history and sexual risk behaviors. METHODS: A total of 1,428 women between 18 and 40 years of age attending family planning clinic appointments completed a self-report survey regarding their recent sexual behaviors and sexual and physical abuse history. Logistic regressions using backward elimination were conducted to identify factors associated with sexual risk behavior. RESULTS: A history of physical abuse by a romantic partner was associated with several sexual risk behaviors. Few significant associations between intrafamilial physical or sexual abuse and recent sexual risk behaviors were found. Additionally, there was no evidence that these relationships were mediated by binge drinking or depressive symptomatology. CONCLUSIONS: Familial abuse experiences are not necessarily associated with recent sexual risk behaviors among adults. In contrast, physical abuse experiences, particularly those perpetrated by a romantic partner, are associated with engaging in adult sexual risk behaviors among women. However, these associations are not mediated by alcohol use or depressive symptomatology. 相似文献

This article addresses the question of whether the concept of competence-based vocational education and training (VET) is transferable from one cultural context to another. Drawing on theoretical concepts of comparative education and sociological neo-institutionalism, the competence-based VET is defined as a new paradigm and situated within its cultural context. Then a case study of an educational transfer from Switzerland to India is presented. The article concludes that the pedagogical concept of competence-based VET is not universally applicable but includes culturally coined ideas, which need to be taken into account when trying to implement it in distant institutional contexts. 相似文献
