Abstract Adventure education philosophers have argued that controlled exposure to challenge can enhance participants' psychological resilience. This study supports this claim, demonstrating significantly greater gains in psychological resilience for 41 young adults participating in 22-day Outward Bound programs than in a control group. All Outward Bound participants reported positive changes in their resilience and their overall change effect size was large. Perceived levels of social support predicted 24% of the variance in resilience gain scores, with participants' ratings of the least supportive group member being the best predictor. The findings for enhanced resilience and the important role of social support warrant wider investigation. In promoting psychological resilience adventure educators are alerted to the importance of facilitating positive interpersonal relations and minimising the detrimental impact of the diverse needs of group members. 相似文献

Executive functions (EF) can be promoted by classroom interventions. Our study investigated whether (a) an intervention conducted by teachers improves EF in children; (b) there are effects on behaviour and academic achievement; and (c) there are stable benefits in a one-year follow-up. Fifty-eight first-graders, divided into experimental (EG = 28) and control (CG = 30) groups, were assessed in EF, reading and arithmetic tests. Parents and teachers answered EF and behaviour functional scales. The intervention was conducted by teachers in the classroom context. EG children showed greater gains in EF and outperformed controls on reading and arithmetic measures. The EG maintained better performance in the one-year follow-up and showed transfer effect for behaviour measures. The EF intervention may be a useful tool for promoting improved adjustment and academic achievement. 相似文献

Abstract The purpose of this study was to evaluate the effects of moderate- to high-intensity resistance and concurrent training on inflammatory biomarkers and functional capacity in sedentary middle-aged healthy men. Participants were selected on a random basis for resistance training (n = 12), concurrent training (n = 11) and a control group (n = 13). They performed three weekly sessions for 16 weeks (resistance training: 10 exercises with 3 × 8–10 repetition maximum; concurrent training: 6 exercises with 3 × 8–10 repetition maximum, followed by 30 minutes of walking or running at 55–85% [Vdot]O2peak). Maximal strength was tested in bench press and leg press. The peak oxygen uptake ([Vdot]O2peak) was measured by an incremental exercise test. Tumour necrosis factor-α, interleukin-6 and C-reactive protein were determined. The upper- and lower-body maximal strength increase for both resistance (+42.52%; +20.9%, respectively) and concurrent training (+28.35%; +21.5%, respectively) groups (P = 0.0001).[Vdot]O2peak increased in concurrent training when comparing pre- and post-training (P = 0.0001; +15.6%). No differences were found in tumour necrosis factor-α and interleukin-6 for both groups after the exercise. C-reactive protein increased in resistance training (P = 0.004). These findings demonstrated that 16 weeks of moderate- to high-intensity training could improve functional capacity, but did not decrease inflammatory biomarkers in middle-aged men. 相似文献

ABSTRACTPurpose: To analyze the Brazilian experience in designing and implementing a recent extension policy reform based on agroecology, and reflect on its wider theoretical implications for extension reform literature. Design/methodology/approach: Using a critical public analysis we characterize the evolution of Brazilian federal extension policy between 2004 and 2015, using political and legal documents as well as recent academic studies for policy frame characterization and implementation analysis. Findings: The case reveals the difficulty of implementing an agroecological extension approach as part of the endogenous development proposal expressed in 2004 PNATER. The agroecological proposal tended to be impaired by a more general demand for diverse public policy programs implementation, facing a series of institutional constraints. A policy reframing process led to a search for alternatives to make it compatible with a federal centralization trend and public administration rules, resulting in a contracting out emphasis. Theoretical implications: The study shows the political economy aspects of extension reform, and how original plans are influenced by path dependence and different and contrasting demands. Practical implications: The study points to the importance of considering political and institutional environments in extension reforms, and indicates a necessity for additional reflection about strategies for scaling up proposals for agroecological and sustainability oriented extension. Originality/value: Few studies are dedicated to understanding the political economy of extension reform, and reform of Brazilian rural extension systems. 相似文献

This article aims to shed light on the current debate regarding the role of internships in higher education in graduates’ employability. In specific, it analyses empirical data on a large-scale study of Portuguese first-cycle study programmes, in order to explore indicators of the professional value of internships in the employability of higher education graduates. Results demonstrate that study programmes that include internships tend to significantly enhance graduates’ employability, particularly within the universe of polytechnic and public higher education institutions. Besides the instrumental value of internships, the impact of the nature and structure of the internship on the percentage of unemployed graduates are also discussed. Mandatory internships and the inclusion of multiple, shorter internships throughout the degree are negatively associated with unemployment levels. Results indicate work-based learning can be used as a successful strategy to bridge theoretical knowledge and practice and enhance graduate employability. These findings provide important insights for the evaluation and/or the design of internship programmes in higher education. 相似文献

Access to higher education in Portugal is governed by a quota system (numerus clausus). The purpose of this article is to answer two questions: First, how does the numerus clausus system shape the demand for medical studies? Second, how do non-enrolled medical candidates influence the global allocation system and generate waves of dissatisfaction? The results show that students who do not succeed in entering medicine register in other programmes, such as pharmacy, veterinary medicine and dental studies, generating a first wave of dissatisfaction. Because students who are not placed in medicine occupy a large share of the places available in those other programmes, the wave of dissatisfaction propagates, with students being pushed to other programmes, especially biology and biochemistry. This process has also been analysed from a spatial perspective. Apparently, when students are competing to obtain a study place in a programme with prestige and good professional career perspectives such as medicine moving to a more peripheral region becomes more frequent. 相似文献

ABSTRACTNurturing students’ continuous learning is a current trend in the higher education agenda. Curricula and academic contents should enable students to take part in stimulating learning experiences, as well as promoting both developing and training opportunities in the course of their lives and careers. Despite the relevance given to lifelong learning in the educational system, there are still some open questions: how this concept is understood and put into practice by higher education institutions? The paper aims to analyse the conceptions of lifelong learning as reflected on the learning outcomes proposed in a sample of study programs. A qualitative methodology and a data-driven approach are adopted to explore the content of the learning outcomes proposed in 10% of total study programs submitted to quality accreditation, since 2009. Generally, results reveal that higher education institutions are committed to the lifelong learning paradigm, particularly in master and PhD degrees. Students are expected to ‘invest in personal and professional development through life’, to ‘develop learning competences through life’, as well as to ‘foster lifelong learning’. This study provides a better understanding of the range of perspectives and the relevance given to lifelong learning as a valuable learning outcome. 相似文献

The present work deals with recent results on the sampling distribution of the magnitude-squared coherence (also called just coherence) estimate between a random (Gaussian) and a periodic signal, in order to obtain analytical critical values, alternative expressions for the probability density function (PDF) as well as the variance and bias of the estimate. A comparison with the more general case of coherence estimation when both signals are Gaussian was also provided. The results indicate that the smaller the true coherence (TC) values the closer both distributions become. The behaviour of variance and bias as a function of the number of data segments and the TC is similar for both coherence estimates. Additionally, the effect of a normalizing function (Fisher's z transform) in the coherence estimated between a random and a periodic signal was also evaluated and normality has been nearly achieved. However, the variance was less equalized in comparison with coherence estimate between two Gaussian signals. 相似文献
