Honduras has made steady progress in expanding post-primary school coverage in recent years, but many rural communities still do not provide a middle (lower secondary) school. As a result, Honduras has implemented a number of middle school alternative programmes designed to meet the needs of at-risk populations throughout the country. This article analyses dropout in three of the four main alternative lower secondary school programmes in Honduras over a three-year period for a cohort of roughly 5,500 students. The results show that these programmes are indeed reaching a vulnerable population in the country, but dropout rates are generally very high – upwards of 50 per cent in some cases – between Grades 7 and 9. Furthermore, even in the control school comparison samples made up of formal lower secondary schools, about 25 per cent of children leave school between Grades 7 and 9. The authors’ analysis includes propensity score matching (PSM) methods that make more focused comparisons between students in alternative programmes and control samples. These results show that dropout rates in alternative programmes are not much different than in control schools, and only significant in one programme comparison, when taking into account family background characteristics like socioeconomic status (SES). Multivariate analysis within alternative programme samples finds that attrition is lower in those learning centres which have adopted key features of formal schools, such as university-educated teachers. The results highlight the tremendous variation in the alternative middle school sector in terms of programme features, school quality and student outcomes, as well as the challenges of expanding this sector to meet the growing demand for lower secondary schooling in Honduras. 相似文献

Purpose: This study explored the effect of whole-body vibration (WBV) using accelerations of 2.56 g to 7.68 g on lower-body detraining. Methods: All participants (N = 20) were trained using a lower-body resistance-training program for 30 min twice per week from Week 0 to Week 6. At the end of the program, they were randomly assigned to a control group that performed no further training or a WBV group that performed a progressive static WBV program. Data for the 5-repetition-maximum (5RM) squat and extensors and flexors of the knee and ankle were collected at Weeks 0, 6, 8, 10, and 12 for all participants. Results: Two-way (condition vs. time) analysis of variance revealed that although the WBV group maintained strength in the 5RM from Week 6 through Week 8 and the control group had a lower 5RM in Week 8 from Week 6, no differences in the 5RM squat existed between the groups at Week 8. Two-way factorial multivariate analysis of variance revealed no differences between the groups at any of the time for torque of knee flexion, dorsiflexion, or plantar flexion. Conclusion: Static WBV of 2.56 g to 7.68 g did not attenuate detraining of the flexors and extensors of the knee and ankle. 相似文献

This study examined the interactive effect of educational structure and a psychological trait, locus of control, on pupil attitudes. Subjects were 660 pupils in open and traditional classrooms in grades 4, 6, and 8. Catalytic interactions in the hypothesized directions were supported by the data (p <.05), with internals more satisfied in open, low-structured environments. This trend was more pronounced for males than females. The TTI paradigm (educational Treatment-personality Trait-Interaction) exemplified by this study may provide common ground for mutual inquiry by educational researchers, school psychologists and school practitioners. 相似文献

This study examines the choice, pattern, and timing of sequential modes of entry among multinational corporations investing in China. Specifically, we examine how earlier choices of entry modes influence decisions ahout subsequent modes of entry in a targeted host country. Six hypotheses are developed and tested using a longitudinal sample of 228 Fortune Global 500 firms that have had multiple entries in China between 1979 and 1996. The results provide supportive evidence of our hypotheses. Specifically, firms employed entry modes reflecting low commitment in early stages that were gradually escalated to higher commitment in subsequent decisions. This is consistent with the “incremental in vestment” approach that underlies traditional and contemporary theories and research in market entry decisions. An analysis of entry mode choices over time reveals different learning patterns: the logic of incremental investments (i.e., the escalation of low to high resource commitments); the logic of the “catch‐up” follower (i.e., relatively heavy commitment at later stages); and the logic of stable, consistent investments (i.e., the continuation of the same entry mode throughout the time period. There is moderate but inconclusive support for country of origin as a moderating factor. The implications of this study for theory and practice are discussed, as well as its limitations. 相似文献
