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

This meta-analysis investigated the maturation-related pattern of adaptations to resistance training in boy athletes. We included studies examining the effects of 4–16-week resistance training programmes in healthy boy athletes aged 10–18 years. Pooled estimates of effect size for change in strength across all studies (n = 19) were calculated using the inverse–variance random effects model for meta-analyses. Estimates were also calculated for groups based on likely biological maturity status (“before”, “during” and “after” peak height velocity). Using the standardised mean difference, resistance training increased strength across all groups (effect size = 0.98, [CI: 0.70–1.27]). Strength gains were larger during (1.11 [0.67–1.54]) and after (1.01 [0.56–1.46]) peak height velocity than before (0.5 [?0.06–1.07]). Adaptations to resistance training are greater in adolescent boys during or after peak height velocity. These findings should help coaches to optimise the timing of training programmes that are designed to improve strength in boy athletes.  相似文献

ABSTRACT

The aim of this article is to show the result of research into the situation of the integration of visually impaired children in Seville (Spain). This work refers to both classroom and peripatetic teachers’ perspectives. We have worked with four peripatetic teachers and nine classroom teachers from Seville. We have used qualitative methodological procedures for data collection and analysis. The results indicate that classroom organization is the most important problem in integration, and within this problem the relationship between classroom and peripatetic teachers becomes a fundamental issue.  相似文献

After more than 20 years since the introduction of ecological and dynamical approaches in sports research, their promising opportunity for interdisciplinary research has not been fulfilled yet. The complexity of the research process and the theoretical and empirical difficulties associated with an integrated ecological-dynamical approach have been the major factors hindering the generalisation of interdisciplinary projects in sports sciences. To facilitate this generalisation, we integrate the major concepts from the ecological and dynamical approaches to study behaviour as a multi-scale process. Our integration gravitates around the distinction between functional (ecological) and execution (organic) scales, and their reciprocal intra- and inter-scale constraints. We propose an (epistemological) scale-based definition of constraints that accounts for the concept of synergies as emergent coordinative structures. To illustrate how we can operationalise the notion of multi-scale synergies we use an interdisciplinary model of locomotor pointing. To conclude, we show the value of this approach for interdisciplinary research in sport sciences, as we discuss two examples of task-specific dimensionality reduction techniques in the context of an ongoing project that aims to unveil the determinants of expertise in basketball free throw shooting. These techniques provide relevant empirical evidence to help bootstrap the challenging modelling efforts required in sport sciences.  相似文献

Abstract

Since 1947, distance education in Mexico has had an important role for nonconventional populations. Considering that distance education is a heterogeneous and dynamic field, it is important to reflect on the need to improve quality as measured by our own standards. With that perspective in mind, a national meeting was organized to start a self‐diagnosis in which quality and access were the main concerns. Five hundred and twenty specialists from fifty‐one institutions participated in a national interactive synchronous meeting held in four regions. As a result of the meeting, thirty‐five criteria and 230 parameters of quality were established. The main conclusion of the meeting refers to the need for the elaboration of our own indicators for open and distance education.  相似文献
