The extent to which school neighbourhood affects teachers’ work commitment is poorly known. In the current study, we investigated whether school neighbourhood socio-economic characteristics predicted teachers’ organizational and professional commitment. Primary school teachers (n?=?1042) responded to surveys in 2000–2001 (baseline) and 2004 (follow-up). Their responses were linked to records of the school neighbourhood income and unemployment levels obtained from nationwide registers. Teachers working in areas with a high income level and low unemployment rate had longer job tenure and higher probability of organizational (school) commitment at follow-up compared to teachers working in areas with a low income level or high unemployment rate. Less consistent associations were found for professional commitment. These findings suggest that school neighbourhood characteristics may affect teachers’ work commitment, especially their organizational commitment. Further research is needed to determine whether this increases inequalities in children’s learning opportunities. 相似文献

In this paper, we expose the unique challenges confronting graduate field-ecology students and the coping strategies they adopt to overcome such challenges. To do so, we used a qualitative (in vivo) research method that combines interviews, observations and open questionnaires with a group of five Israeli graduate students. The two major challenges that the students faced were the uncontrolled nature of field research (or complexity), and the nature of field setting, which isolated the students from authoritative guidance. In response to these challenges, the students developed a set of research skills which were expressed in this study by a series of three (metacognitive) strategies which we designated as ‘protocol-dominated’, ‘intermediate’ or ‘field-dominated’. In order to develop such research skills, our subjects rely upon declarative and procedural knowledge. In contrast to declarative knowledge, learned in coursework, procedural knowledge is learned and activated via the situated experience of implementing research in authentic field environments. We also found that fieldwork complexity imposes itself the minute the students step into the field; potentially, this can negatively impact students' motivation. However, as the students accumulate field experience and acquire the knowledge and skills needed to overcome the field's complexity, their motivation improves. Recognizing the unique learning components connected to field research will help novice students better cope with fieldwork challenges, as well as help their advisers in guiding them. This work also has implications for designing inquiry curricula in field sciences for university and high-school students. 相似文献

ABSTRACTPrevious research on unstable footwear has suggested that it may induce mechanical noise during walking. The purpose of this study was to explore whether unstable footwear could be considered as a noise-based training gear to exercise body center of mass (CoM) motion during walking. Ground reaction forces were collected among 24 healthy young women walking at speeds between 3 and 6 km h?1 with control running shoes and unstable rocker-bottom shoes. The external mechanical work, the recovery of mechanical energy of the CoM during and within the step cycles, and the phase shift between potential and kinetic energy curves of the CoM were computed. Our findings support the idea that unstable rocker-bottom footwear could serve as a speed-dependent noise-based training gear to exercise CoM motion during walking. At slow speed, it acts as a stochastic resonance or facilitator that reduces external mechanical work; whereas at brisk speed it acts as a constraint that increases external mechanical work and could mimic a downhill slope. 相似文献

Sleep disorders have become increasingly prevalent affecting health and working ability. Restorative sleep may be considered important for athletes’ successful recovery and performance. However, some athletes seem to experience major problems in sleeping. Thus far, there is limited scientific information about their sleep. This study aimed to evaluate the quality of sleep and the prevalence of sleep disorders as well as the impact of a structured sleep counselling protocol in professional athletes. A total of 107 professional ice hockey players participated in the study. The exploratory observational 1-year follow-up study consisted of questionnaire-based sleep assessment followed by general sleep counselling and, when needed, polysomnography and an individual treatment plan. One in every four players was found to have a significant problem in sleeping. All athletes considered sleep essential for their health and three in every four players considered that counselling would improve their performance. Counselling and individual treatment were found to improve significantly the quality of sleep with the mean alteration of 0.6 (95% CI 0.2–1.0, P = 0.004) in a scale from 0 to 10. Our results support that sleep problems are common in professional athletes. However, systematic examination, counselling and individual treatment planning can improve the quality of their sleep. 相似文献

In this study, we examined the effect of rapidly increased training volume and intensity on hormonal responses (salivary cortisol [C] and urinary dehydroepiandrosterone sulphate [DHEA-S]) and recovery-stress state perceived by 12 female cyclists. Over the 4-day experimental period, there was an average increase in training load of approximately 122% compared with that during the previous 12 days. Scores on subscales of the Recovery Stress Questionnaire for Athletes increased for the somatic component of stress (Fatigue, Emotional Stress and Social Stress; P<0.05) and decreased the factor indicating recovery (General Well Being; P<0.05) after the heavy training period. The training programme increased resting concentrations of salivary cortisol (P<0.05) and decreased the DHEA-S/C ratio (P<0.05). The increase in training load of cyclists was correlated with this hormonal ratio (r=-0.48, P<0.05). Changes in resting cortisol concentration as a result of heavy training stress were positively related to the change in Physical Complaints (r=0.69, P<0.01). Negative relationships were also found between changes in the DHEA-S/C ratio and changes in the somatic component of stress. The present results suggest that there is a dose-response relationship between increased training load, resting DHEA-S/C ratio and subjective assessment of stress and recovery, implying that this ratio could be used as an indicator of training status in female athletes. 相似文献

Abstract Despite little improvement in the socio‐political predicament of Okinawa since its reversion to Japan, culturally there has recently been something of an ‘Okinawa boom’ in mainland Japan. This has involved a huge interest in Okinawa and Okinawan cultures in mainland Japan and an increasing ‘consumption’ of Okinawan goods and cultural artefacts. One of the symptoms of this trend has been the growth in the last five years or so, in the number of films set in Okinawa. Many of these films present conventional stereotypical images of Okinawa and, whether wittingly or not, have contributed to the ‘cosmetic operation’ of Japan’s multiculturalism by providing a utopian vision of Okinawanness and erasing Okinawa’s problems from the screen. However, an Okinawan filmmaker, Takamine Go, critically challenges such stereotypes and Japan’s cosmetic multiculturalism. This paper focuses on Takamine’s Untamagirū (1989) and Tsuru‐Henry (1999). It examines the cinematic strategies mobilised by these films – the use of different languages, allegorical implications, complex montages of image and sound, and the departure from conventional narrative realism. These strategies, it will be suggested, not only enable the films to explore complex forms of public memory and history but also to challenge the notion of a homogeneous Japan and its ‘quasi‐orientalist’ gaze towards Okinawa. The paper then proceeds to argue that Takamine’s films should not simply be regarded as a ‘regional’ variant of Japanese cinema but as a ‘specifically Okinawan cinema’ that both overlaps with and opposes a ‘national’ Japanese cinema. 相似文献

BACKGROUND: The use of a structured abstract has been recommended in reporting medical literature to quickly convey necessary information to editors and readers. The use of structured abstracts increased during the mid-1990s; however, recent practice has yet to be analyzed. OBJECTIVES: This article explored actual reporting patterns of abstracts recently published in selected medical journals and examined what these journals required of abstracts (structured or otherwise and, if structured, which format). METHODS: The top thirty journals according to impact factors noted in the "Medicine, General and Internal" category of the ISI Journal Citation Reports (2000) were sampled. Articles of original contributions published by each journal in January 2001 were examined. Cluster analysis was performed to classify the patterns of structured abstracts objectively. Journals' instructions to authors for writing an article abstract were also examined. RESULTS: Among 304 original articles that included abstracts, 188 (61.8%) had structured and 116 (38.2%) had unstructured abstracts. One hundred twenty-five (66.5%) of the abstracts used the introduction, methods, results, and discussion (IMRAD) format, and 63 (33.5%) used the 8-heading format proposed by Haynes et al. Twenty-one journals requested structured abstracts in their instructions to authors; 8 journals requested the 8-heading format; and 1 journal requested it only for intervention studies. CONCLUSIONS: Even in recent years, not all abstracts of original articles are structured. The eight-heading format was neither commonly used in actual reporting patterns nor noted in journal instructions to authors. 相似文献

Translation of a literary work is never an automatic process but always poses many problems caused by the differences between two linguistic and cultural systems. The difficulty seems to be enhanced if the work to be translated is for children who have little knowledge about the culture from which the text originates. At least, that must be the idea behind the practice of replacing foreign names with familiar ones, a practice still common in English and German translations. The present argument is that this change not only shows a lack of respect toward other cultures but also deprives child readers of the chance to realize the wealth of cultural diversity that surrounds them. 相似文献

For migrant groups moving from one place to another usually means dealing with contradictions between home and host countries and with different cultural norms. Taking into consideration migrant women's previous status in the village and their new one in the host country, it can be said that migration is a turning point in women's lives. Research findings show that increased employability of women in the host country increases their independence and leads to sex role changes and changes within the family.Return migration is the last stage in the migration cycle and it is a rather neglected and little researched topic as yet. The purpose of this paper is to report on research on role changes within the family.Three groups of migrant mothers (two groups living in West Germany and one group repatriated) were compared with a control group in the District of Drama, Macedonia, on work employment and types of responsibilities concerning their children's upbringing.Results showed that mothers who live in West Germany are equally responsible with fathers for the child's social behavior, school performance and expenses and were significantly different from the control group. Return mothers were as much as fathers responsible for the child's school performance in contrast to the control group. More mothers than fathers, however, were responsible for the child's relationships and fewer mothers than fathers were responsible for the child's expenses; in this respect both parents resembled those of the control group. It seems therefore, that migrant mothers take over different roles in the host country than those of the controls, whereas return mothers adopt to a large extent the stereotyped role of control mothers. 相似文献

For Māori, a real opportunity exists to flesh out some terms and concepts that Western thinkers have adopted and that precede disciplines but necessarily inform them. In this article, we are intent on describing one of these precursory phenomena—Foucault’s Gaze—within a framework that accords with a Māori philosophical framework. Our discussion is focused on the potential and limits of colonised thinking, which has huge implications for such disciplines as education, among others. We have placed Foucault’s Gaze alongside a Māori metaphysics and have speculated on the Gaze’s surveillant/expectant strategies with some key Māori primordial phenomena in mind, such as ‘te kore’ (nothingness) and ‘āhua’ (form). We posit the Gaze as an entity and thus aim to render it more relevant to Māori, so that it can be addressed appropriately. We also (but relatedly) preface that discussion by theorising on some of the challenges that confront us as Māori authors in even referring counter-colonially to the Gaze. Whilst we do not seek to destabilise the Gaze by positing it as a metaphysically based entity, we do hint at the possibility that critical indigenous philosophy may even for a short time bring the Gaze into focus for Māori. By introducing an awareness of an alternative (Māori) metaphysics, we may have unsettled the self-certainty of the Gaze. 相似文献
