The effects of under‐skilling on need for recovery,losing employment and retirement intentions among older office workers: A prospective cohort study

Based on a sample of older workers from the Maastricht Cohort Study, the authors investigate the prevalence and dynamics of self‐reported under‐skilling and its effects on workers' need for recovery, their risk of losing employment and their retirement intentions over a two‐year period. They find that being under‐skilled is associated both with higher levels of need for recovery over time and with the risk of losing employment, but not with early retirement intentions. To achieve sustainable employment, they argue, the course of under‐skilling should be monitored throughout workers' careers, enabling timely interventions to avoid its negative consequences.     

Communicative competence and the facilitating and perturbing factors in the socialisation of immigrant students

This work analyses the communicative competence and the factors that facilitate and perturb the socialisation of immigrant students in primary education. It provides greater knowledge concerning the relationship between the immigrant student's social and linguistic competence. It also analyses the presence of difficulties in the different language components (morphology, syntax, semantics and pragmatics). The sample is made up of a total of 326 immigrant students between 6 and 12 years of age, attending 10 different schools. The study demonstrates that immigrant students possess a low level of linguistic dominion. All the linguistic components analysed are affected, although greater difficulties are evident in morphology and syntax than in semantics and pragmatics. The relationship between linguistic competence and the factors that facilitate and perturb socialisation is underlined. This work concludes that there is a significant relation between semantics and pragmatics and several socialisation factors (leadership, aggressiveness–stubbornness and anxiety–shyness). The educational centres should be aware of the complicated learning process that immigrant students have to go through.     

Health Technology Literacy: A Transdisciplinary Framework for Consumer-Oriented Practice

Abstract

The present study developed a typology of self-reported coping strategies used by older adults in adapting to vision impairment using qualitative analyses. Narrative data were examined from three previous quantitative studies of adaptation to vision loss. Major themes in coping with vision loss included difficulty in balancing norms of independence with the functional losses resulting from eye disease, and the importance of the informal social network. Importantly, a number of coping mechanisms that have not been examined in prior quantitative work were identified through the present qualitative analyses. Implications of this typology of self-reported coping with age-related vision loss for research and practice are discussed.     

Adaptive Estimation of the Integral of Squared Regression Derivatives

A problem of estimating the integral of a squared regression function and of its squared derivatives has been addressed in a number of papers. For the case of a heteroscedastic model where smoothness of the underlying regression function, the design density, and the variance of errors are known, the asymptotically sharp minimax lower bound and a sharp estimator were found in Pastuchova & Khasminski (1989). However, there are apparently no results on the either rate optimal or sharp optimal adaptive, or data-driven, estimation when neither the degree of regression function smoothness nor design density, scale function and distribution of errors are known. After a brief review of main developments in non-parametric estimation of non-linear functionals, we suggest a simple adaptive estimator for the integral of a squared regression function and its derivatives and prove that it is sharp-optimal whenever the estimated derivative is sufficiently smooth.

从历史中突破——历史素材影院动画片的改编

按照动画的传播手段来说，通过电影进行传播的动画片是其中一种最主要的形式，而有一定长度、有故事情节的“影院动画片”更是在观众中最具影响力，它的优劣程度已成为考察一个国家动画制作水平高低的一个标准。但是从目前的实际情况来看，我国的影院动画片的水平仍然远远落后于世界水平。通过考察目前中国影院动画片现状，提出制约影院动画片发展的最主要原因是剧本，同时通过分析指出，对历史素材进行改编是解决当前中国影院动画片落后的有效途径。     

审美调适与和谐心理的建构

和谐健康的个体心理是和谐社会的基础,而审美调适则是保持心理健康的重要途径之一。本文提出的审美调适这一概念,是指运用丰富生动的美感对个体心理进行调整、改善、充实、优化,通过情感的"高峰体验"和审美超越的作用,使心理结构在美感的强烈刺激下经受锻炼而更加坚强,并由此获得精神上的解放。审美调适的主要方式则是通过对心理偏激和心理落差的调整来实现心理结构的动态平衡,而审美活动对心灵的调养滋润是保持心理和谐的基本方式,崇高事物和悲剧艺术对否定性情感的宣泄则以相反相成的方式成为审美调适不可或缺的因素。     

中学教师职业倦怠的状况分析

教师心理健康问题得到广泛关注,而职业倦怠是近年来关注的热点。对170名中学教师进行职业倦怠情况调查的结果表明,中学教师的职业倦怠程度并不严重,但仍有一定比率的教师经历严重的倦怠。调查结果还发现,女性教师、重点学校的教师、工作2至3年和工作11至20年两个教龄段的教师更多地经历情绪衰竭;未婚教师在去个性化维度上得分更高。未来研究需要探讨预防和缓解教师发生职业倦怠的干预措施。
