The influence of recent social and economicchanges in the Israeli kibbutz on the prolongedstage of youth was examined with respect tohigher education. The young people on thekibbutz of the late 1990s appear lessmoratorial and more instrumental about theirfuture and commence higher education earlierthan in previous age cohorts. When starting tostudy, their educational and professionalprospects are crystalized as those of thenon-kibbutz student. Most of them opt foracademic, degree-granting studies, but a higherpercentage than among the general populationprefer vocation-oriented colleges to theresearch oriented universities. In choosingfields of study, they prefer more appliedstudies like engineering, social services andpractical arts and are less likely to choosesciences and the humanities. De-communalizationand economic instability of the kibbutz,inadequate preparation in kibbutz high schoolsfor the competitive admission to theuniversities, exposure to a restricted range ofoccupations during adolescence, and lack of acultural tradition supportive of elitiststudies may explain this practical mood, moresalient among kibbutz women. 相似文献

ABSTRACTThis study examined the reliability and validity of three methods of estimating the one-repetition maximum (1RM) during the free-weight prone bench pull exercise. Twenty-six men (22 rowers and four weightlifters) performed an incremental loading test until reaching their 1RM, followed by a set of repetitions-to-failure. Eighteen participants were re-tested to conduct the reliability analysis. The 1RM was estimated through the lifts-to-failure equations proposed by Lombardi and O’Connor, general load-velocity (L-V) relationships proposed by Sánchez-Medina and Loturco and the individual L-V relationships modelled using four (multiple-point method) or only two loads (two-point method). The direct method provided the highest reliability (coefficient of variation [CV] = 2.45% and intraclass correlation coefficient [ICC] = 0.97), followed by the Lombardi’s equation (CV = 3.44% and ICC = 0.94), and no meaningful differences were observed between the remaining methods (CV range = 4.95–6.89% and ICC range = 0.81–0.91). The lifts-to-failure equations overestimated the 1RM (3.43–4.08%), the general L-V relationship proposed by Sánchez-Medina underestimated the 1RM (?3.77%), and no significant differences were observed for the remaining prediction methods (?0.40–0.86%). The individual L-V relationship could be recommended as the most accurate method for predicting the 1RM during the free-weight prone bench pull exercise. 相似文献

ABSTRACT Implementation of educational integration policy in Israel creates heterogeneous student compositions in the schools. Principals and teachers who, as a result, confront instructional difficulties, and who are ambiguous about this policy and its expected efficacy, press to counter‐balance this heterogeneity by resegregating students within the school in ability‐based classes. In this paper we deal with three inter‐related topics:
-
the degree of learning segregation within integrated junior high schools in Israel;
-
several factors which may explain the degree of learning segregation; (3) the effect of learning segregation on academic outcomes: achievement (in reading and science) and subsequent school career (student placement in high school track).

School integration (desegregation) was introduced in Israeli junior high schools in 1968 with the aim of increasing educational equality and decreasing (Jewish) ethnic divides. While never officially abandoned, a de facto retreat from this policy has been observed since the early 1990s, despite the voluminous research that revealed its positive, though moderate, educational outcomes. This shift in educational emphases reflected profound societal changes, fed by global neo‐liberal trends and educational consumerism, which research‐based arguments supporting integration were too weak to resist. The ascent and waning of school integration in Israel provide an instructive case for analysing the interconnection of educational policy, educational research, and societal changes, demonstrating the weakness of research in sustaining educational policy in the face of counteracting social and political developments. 相似文献

The landing error scoring system (LESS) assesses the quality of a landing after a jump. The quality of the jump is usually evaluated using a three-dimensional (3-D) motion analysis system or a two-dimensional (2-D) video analysis visually rated by a clinician. However, both methods have disadvantages. The aim of this study was to examine the concurrent validity of a novel portable motion analysis system (‘PhysiMax System’) in assessing the LESS score by comparing it to video analysis. The study population included 48 healthy participants (28.45 ± 5.61 years), each performing the LESS test while two video cameras and the ‘PhysiMax’ simultaneously recorded the jump. The ‘Physimax’ system automatically evaluated the LESS. Subsequently, the examiners scored the test by viewing the video recordings, blinded to the ‘PhysiMax’ results. The mean LESS score, using the video recordings and the ‘PhysiMax’ was 4.77 (±2.29) and 5.15 (±2.58), respectively, (ICC = 0.80, 95% confidence intervals 0.65–0.87), mean absolute differences 1.13 (95% confidence intervals; 0.79–1.46). The results indicate a high consensus between the methods of measurement. The ‘Physimax’ system’s main advantages are portability, objective evaluation and immediate availability of results. The system can be used by athletic trainers and physiotherapists in the clinic and in the field for jumping assessment. 相似文献

In this paper we present new evidence on the impact of school characteristics on secondary student achievement using a rich dataset from rural Bangladesh. We deal with a potentially important selectivity issue in the South Asian context: the non-random sorting of children into madrasas (Islamic faith schools). We do so by employing a combination of fixed effects and instrumental variable estimation techniques. Our empirical results do not reveal any difference in test scores between religious and secular schools when selection into secondary school is taken into account. However, we document significant learning deficit by gender and primary school type: girls and graduates of primary madrasas have significantly lower test scores even after controlling for school and classroom-specific unobservable correlates of learning. 相似文献
