ABSTRACT Precarious jobs and unemployment have become common issues for many young adults due to the unfavourable labour market situation in Portugal. Against this background, lifelong learning (LLL) policies have been called in to play a role in creating economic growth and supporting the social inclusion of young adults in vulnerable educational and economic circumstances. These policies are defined at the national level; however, their implementation depends on the action of local actors who face specific challenges. This paper explores disparities in the definition and implementation of LLL policies targeting young adults in two Portuguese regions. Specifically, we analyse professional courses in Vale do Ave (North) and adult education and training courses in Alentejo Litoral (South). These regions were selected due to their dissimilar economic structure. This study adopted a qualitative approach through interviews with LLL experts and policy roundtables with local stakeholders and decision-makers in both regions. Data were transcribed and analysed using NVivo 10. The study shows that the two regions have different cooperation networks between local stakeholders, and that these impact the opportunities to influence the regional skills formation system differently. Also, the study shows that LLL policies are not designed to address destandardised life courses. 相似文献

ABSTRACT The past 20 years have seen major efforts to extend and reform the system of general education in Spain. Some of the most important reforms are contained in legislation passed in 1990. These developments have direct relevance to the reform which has also been taking place in the system of special education. Official policy is that integrated provision should be available in all schools, but in the short term the system has set itself an initial and more limited objective. 相似文献

In this paper the origins and development of peer culture are charted through the identification and analysis of children's peer routines in the Italian asilo nido and scuola matema. In the asilo nido the children produced several primarily nonverbal play routines which had identifiable participant structures and were produced consistently over the course of the school year. In the scuola matema the children produced a variety of both verbal and nonverbal routines. The authors give a detailed analysis of one routine, the children's construction and participation in verbal debate or discussione. They then compare features of the routines in the asilo nido and scuola matema in an attempt to capture the origins and development of peer culture in the Italian preschool educational system. 相似文献

Two experiments evaluated history effects on induced and operant variability. College students typed three-digit sequences
on a computer keyboard. Sequence variability was induced (by no reinforcement or variation- independent reinforcement) or
reinforced (by variation- or repetition-dependent reinforcement). Conditions with induced and operant variability were presented
according to a reverse between-groups design. In Experiment 1, we examined transitions from the variation or repetition contingencies
to no reinforcement, and vice versa. In Experiment 2, the variation or repetition contingencies were followed or preceded
by variation-independent reinforcement. The results showed that (1) a history of no reinforcement impaired operant variability
learning; (2) induced variability levels were higher and lower after a history of reinforcement for variation and repetition,
respectively; (3) repetition was more easily disrupted by no reinforcement and independent reinforcement than was variation;
and (4) response variability and stability were a function of past and current reinforcement conditions. These results indicate
that reinforcement history influences both induced and operant variability levels. 相似文献

AbstractThe purpose of this study was to investigate the association between relay exchange block time and final performance in 4 × 100-m and 4 × 200-m freestyle and 4 × 100-m medley relays as a function of sex (men and women) and classification (medallists and non-medallists) in international competitions. Nineteen international competitions covering a 13-year period (2000–2012) were analysed retrospectively. The data corresponded to a total of 827 team relay histories (407 men, 420 women). Kruskal–Wallis and Mann–Whitney tests were performed to determine any differences by sex, classification, and event. Similarly, the relationship between the exchange block times and final performance was examined by means of a Pearson correlation analysis. In the three events, the men’s exchange block times were shorter than those of the women (η2 = 0.049–0.109; P < 0.001). The exchange block time was especially relevant for the women’s relay medallists in the 4 × 100-m freestyle (r = 0.306, P = 0.021) and 4 × 100-m medley (r = 0.385, P = 0.011), while for men the relationship was clearer for the non-medallists. These results suggest that the exchange block time should be considered as one of the performance parameters of swimming relay starts, and thus should be included explicitly as part of training. In particular, the coach could design training targeted at standardising an optimal exchange block time equal to or less than that expected for other teams in the competition. 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
