ABSTRACTFor many forcefully displaced people worldwide, notions around one’s sense of “home” and “place” in the world are perpetually unsettled. This article explores how digital technologies interact with embodied, material experiences within the geographical location refugees are residing in. Empirical examples from ethnographic research conducted among Iraqi urban refugees, living in prolonged uncertainty in Jordan, shows how situated experiences of legal, material, and social uncertainty reinforce particular mediated socialities. Pivotal studies have shown how digital connections engender virtual home-making practices and a wide variety of connected presences. This study points to the other side of the same coin: the cultivation of “absent presence.” “Absent presence” refers to feelings—the ambivalence that experiences of prolonged displacement bring about—but also to active disengagement and affective tactics in response. These engender a further separation from the physical world where forced migrants are not deemed welcome. 相似文献

ABSTRACTIntroduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required. 相似文献

This study examined the effects of a newly developed on-site consultancy programme to improve global quality of the child care environment in non-parental child care centres for 0- to 4-year-old children as measured with the ITERS-R/ECERS-R. Using a randomised controlled trial with a pretest, posttest, and follow-up test, we compared 35 experimental group with 33 control group. The consultancy programme comprised three consultations in total. Analysis on the items that were specifically targeted during the consultancy showed a significant improvement on these targeted items between pretest and posttest and between posttest and follow-up. The effect of the consultancy programme on the total scores (including the non-targeted items) was not significant. 相似文献

Nowadays, there is a consensus that good teaching and learning needs instructional variation and personalised forms of learning. In teacher education, these concepts have been implemented for years, and prospective teachers are taught accordingly; it is thus assumed that the teaching of novice teachers is in accordance with these new teaching concepts. In the research project ‘ALPHA’, the teaching of novice teachers at the beginning and at the end of their first year in the profession and the teaching of experienced teachers with five or more years of teaching experience was videotaped, so that longitudinal and cross-sectional comparisons were possible. The lessons were analysed by applying a coding system on the instruction and by employing a rater inventory in order to understand the structure and quality of the lessons. Overall, the results indicate high levels of whole class teaching with a rather high level of traditional classroom instruction both for the novice and the experienced teachers. However, the proportions vary depending on the location of teacher education. The results provide evidence that the new teaching concepts learned on the teacher education programme are not necessarily implemented in the classroom and provide possible reasons why this might be the case. 相似文献

In the first part of this study, the football potential of 67 football players was predicted from their scores on a football-potential test. The test battery consisted of motor ability items as well as football skill items. Substantial correlations were obtained between most test items and the test criterion, the sum of T scores. Size, as depicted by McCloy's classification index (C.I.), had a negative, nonsignificant correlation with the criterion. The discriminative power of the battery was evidenced by the highly significant correlation between the test criterion and the coaching staff's ranking of individual players (rho = .840). It was concluded that athletic potential in football can be predicted by testing. In the second part of the study, football teams from three different strata of competition were evaluated on the basis of the test battery. The battery substantiated a step-wise progression between the teams on most items, with significant differences being noted. The test showed validity, in that the test criterion (the sum of T scores) was significantly different between the teams. 相似文献

An effective start enhances an athlete's chances of success in ski cross competitions. Accordingly, this study was designed to investigate the biomechanics of start techniques used by elite athletes and assess the influence of different start environments. Seven elite ski cross athletes performed starts indoors on a custom-built ramp; six of these also performed starts on an outdoor slope. Horizontal and vertical forces were measured by force transducers located in the handles of the start gate and a 12-camera motion capture system allowed monitoring of the sagittal knee, hip, shoulder, and elbow kinematics. The starting movement involved Pre, Pull, and Push phases. Significant differences between body sides were observed for peak vertical and resultant forces, resultant impulse, and peak angular velocity of the shoulder joint. Significantly lower peak vertical forces (44 N), higher resultant impulse (0.114 Ns/kg), and knee joint range of motion (12°) were observed indoors. Although movement in the ski cross start is generally symmetrical, asymmetric patterns of force were observed among the athletes. Two different movement strategies, i.e. pronounced hip extension or more accentuated elbow flexion, were utilised in the Pull phase. The patterns of force and movement during the indoor and outdoor starts were similar. 相似文献

This study provides insight into the quality of practitioner research and the impact of this on the professional development of the individual teacher and the school as a whole. We examined the quality of practitioner research in relation to the goals of the research. We operationalized the quality of the research in terms of the validities outlined by Anderson and Herr. In our study we apply this way of thinking to 11 cases of teacher research in secondary education. We found at least some evidence of outcome validity and catalytic validity for the teachers’ practitioner research. However, evidence of process validity and democratic validity was only found in some of the projects. We conclude that the approach adopted in this study can be more generally used to increase the quality and thereby the impact of practitioner research. 相似文献

According to Bourdieu, habitus is an important, and class-specific, foundation for behaviour. However, he hardly explained how the habitus is acquired. Based on Bernstein's elaboration on the various contexts in which group-specific behavioural principles are acquired, this article demonstrates how young children of two divergent social classes obtain their habitus underlying their sports and exercise behaviour. Although children in both groups acquire a habitus in which sports and exercise play a role, there are striking differences which arise largely out of differences in the impact of socialising agents. Within the higher social class, there is a clearly defined group, namely the nuclear family, which explicitly controls and regulates the children's exercise behaviour. These children learn specific skills at specific places. In the lower social class, the habitus is influenced by the extended family, the physical education teacher and peers, resulting in a broad range of less strictly ordered activities, undertaken at different places. These findings offer a valuable contribution to insight into class-specific socialisation processes, resulting in the acquisition of a specific habitus. 相似文献

Preschool education, including scientific literacy, has recently been receiving increased attention in Germany??s educational system. However, only a few studies have investigated scientific literacy in the preschool age so far. In this paper a test instrument to assess scientific literacy in five year old children is presented. The topic of the test is water, its physical states (solid, liquid and gaseous), changes of state and solutions in water. The test was administered as a structured interview and high reliability and internal validity were obtained. The children investigated show a great variance in their competencies which can be ascribed to four different levels of competence. 相似文献

The present study aimed at investigating children's and adolescents' understanding of constant and accelerated motions. The
main objectives were (1) to investigate whether different task formats would affect the performance and (2) to track developmental
changes in this domain. Five to 16 year olds (N = 157) predicted the distances of a moving vehicle on the basis of its movement durations on both a horizontal and an inclined
plane. The task formats involved: (1) nonverbal action tasks, (2) number-based missing-value word problems, and (3) verbal
judgments. The majority of participants of all age groups based their reactions in the first two task types on the assumption
of a linear relationship between time and distance—which is correct for motions with constant speed but incorrect for accelerated
motions. However, in the verbal judgments that tapped conceptual understanding, children from the age of 8 years onwards correctly
assumed that an object rolling down an inclined plane would accelerate. The role of the task format in evoking erroneous beliefs
and strategies is discussed. 相似文献
