ABSTRACT

The 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   

Output feedback stabilization for symmetric control systems     

Carmen Coll  Néstor Thome 《Journal of The Franklin Institute》2005,342(7):814-823

This work is devoted to the study of symmetric control systems. It establishes a relation between internal symmetry and external one for a linear invariant control system having n real simple poles. The symmetric stabilization problem is studied using a symmetric feedback gain such that the output control stabilizes the closed-loop system. A necessary and sufficient condition is given to solve this stabilization problem for a symmetric control system (A,B,C) and a generalized symmetric control system (E,A,B,C).  相似文献

Resisting Erasure and Developing Networks of Solidarity: Testimonios of Two Puerto Rican Scholars in the Academy     

Carmen M. Martínez-Roldán  Sandra Quiñones 《Journal of Language, Identity & Education》2016,15(3):151-164

In this article, we share findings from a critical qualitative study aimed at better understanding the ways that language, history, and geography mediate our work and identities as educational researchers. As scholars whose particular sociocultural and political histories are often absent in scholarly discussions about language and education, we use the intergenerational sharing of testimonios as both methodology and narrative development to gain a deeper understanding of experiences involving the learning and use of English that influence our academic careers. We theorize our experiences as resisting erasure and contribute to Latina epistemology scholarship and critical educational research about Puerto Ricans in the United States. Moreover, we forward the concept of funds of knowledge as a professional practice. Telling our stories and developing mentoring networks is necessary for our individual and collective functioning and well-being as scholars; it cultivates solidarity as a means of thriving in the academy.  相似文献

‘I’m older but I can still do this job’: the experiences of mature women in an age-sensitive occupation     

Tatiana S Rowson  Maria Del Carmen Gonzalez-White 《Educational gerontology》2019,45(4):248-258

This paper explores how mature female flight attendants [FAs] use Selection, Optimization and Compensation [SOC] strategies to cope with age-related diminishing resources at work. The role of FAs is an age-sensitive occupation, and in some organizations, women are under constant pressure to look young and attractive. This Interpretative Phenomenological Analysis study aims to add depth and nuance to our understanding of SOC strategies qualitatively; most published studies are quantitative. A homogenous sample of 5 mature single Filipina FAs, foreign workers employed by Arabian Gulf-based airlines, were interviewed through a semi-structured protocol. Recruitment was through a snowball process. The study found that FAs use SOC strategies to compensate for age-related decline. Off-duty, their focus is directed to activities that help them to meet the organizations’ expectations of youthful appearance and productivity. To achieve this, resources from other life domains are diverted, which leads to negative outcomes from focusing SOC strategies on only one aspect of life. Despite negative personal implications and concerns about the future, the participants still felt attached to their work identities. This shows the importance of understanding the use of SOC strategies within and across life domains, as well as their implications for career sustainability and workability. The use of such strategies at work when detrimental to other life roles is unsustainable. The findings highlight the importance of conducting more qualitative studies on SOC behaviors of specific groups, so the experiences of aging at work can be explored in more depth, allowing areas of concern to be identified.  相似文献   

Competence-Based Vocational Education and Training and Its Cultural Context Sensitivity     

Carmen Baumeler 《欧洲教育》2019,51(1):1-15

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
