AbstractEcological dynamics of decision-making in the sport of sailing exemplifies emergent, conditionally coupled, co-adaptive behaviours. In this study, observation of the coupling dynamics of paired boats during competitive sailing showed that decision-making can be modelled as a self-sustained, co-adapting system of informationally coupled oscillators (boats). Bytracing the spatial–temporal displacements of the boats, time series analyses (autocorrelations, periodograms and running correlations) revealed that trajectories of match racing boats are coupled more than 88% of the time during a pre-start race, via continuous, competing co-adaptions between boats. Results showed that both the continuously selected trajectories of the sailors (12 years of age) and their categorical starting point locations were examples of emergent decisions. In this dynamical conception of decision-making behaviours, strategic positioning (categorical) and continuous displacement of a boat over the course in match-race sailing emerged as a function of interacting task, personal and environmental constraints. Results suggest how key interacting constraints could be manipulated in practice to enhance sailors' perceptual attunement to them in competition. 相似文献

This article focuses on education in Guinea-Bissau in the context of globalisations, examining the concept of globalisation and its relation to education and the curriculum. It focuses on the relatively neglected area of national education policies in Guinea-Bissau, comparing differences and common points of interference/influence of multilateral (international and regional) and bilateral organisations in these policies. Data collection was based on content analysis of a corpus of documents – the Education Act, the document of Portuguese Cooperation Programme, the Education Sector Policy Paper, the Education for All National Plan of Action, and Policy n. 3/2007/CM/UEMOA – and field notes collected from 2009 to 2012. The article argues that there is a tendency for the homogenisation of curriculum policies, at least at the macro-level, due to the different types of pressures coming from international/regional organisations. 相似文献

随着互联网时代的到来,网络政治参与成为当今民主政治建设的一种新形式与新途径。通过对安徽省5所本科院校的大学生网络政治参与现状的调查,发现大多数大学生关心国家政治,愿意参政议政,大学生网络政治参与已成为民主政治建设的一支重要力量。受网络监管措施不力、自身政治素质不成熟等因素影响,大学生容易被网络上错误舆论诱导,导致盲从行为和群体极化现象。需要采取措施,加强网络监管,提高政府有关部门对大学生网络政治参与行为的反馈效率,以提高大学生政治参与的效能感,激发大学生更高的网络政治参与热情,使其积极发挥"正能量",为推进我国的社会主义民主政治建设作出重要贡献。 相似文献

Grade retention and inequalities that derive from grade retention can influence student school trajectories and careers. Grade retention can discourage students from education, and increase school failure and dropout. This study explored the relationship between grade retention and student intentions to enrol in higher education. We also studied the role of school identification and behavioural engagement in this relationship. The analysis is based on a sample of 1,089 students (grades 6 to 10) from Portugal, one of the European countries with the highest rates of grade retention. We employed multilevel probit regression modelling with random intercept and fixed slopes to explore both the individual and school level effects of grade retention. The analyses showed that retained students had a lower probability of intent to enrol in higher education and that there was a contextual effect of the number of retained students in the school, on students' probability of intent to enrol in higher education. This association was partially explained at the individual level by students' school identification. Retained students presented lower levels of school identification, which in turn results in lower probabilities of enrolling in higher education. Student behavioural engagement was not associated with grade retention nor student intentions. Our findings suggest the need for interventions that foster students' school identification to overcome the adverse effects of grade retention. 相似文献

The work presented is part of a study that the research group CIFO (Research Team in Training for the Labour Market, Autonomous University of Barcelona, Barcelona) has carried out, relating to the training needs analysis and basic competences and skills in the environment of sheltered employment centres (SECs) in Catalonia (this study was undertaken in collaboration with the Coordination of Workshops for People with Mental Disabilities in Catalonia). The analysis and assessment of needs is useful from the perspective of training, as a starting point for planning adapted to the reality of disabled workers in SECs. To do this, various elements such as skills, knowledge and attitudes of individual and social nature have been considered from a systemic approach. By placing ourselves in clearly defined contexts (SECs), we bear in mind the characteristics of workers, the features of the job context, the types of activities performed, the skills related to work activities carried out, the definition of competence profiles required on the basis of the essential skills and the real training needs, through the characteristics of workers and those skills related to the labour activities that are performed as well as the needs for training perceived by workers. Identifying training needs in relation to basic skills and job requirements allows us to meet the challenge, as a trend that supports a competence basis for any worker, of raising general actions that may govern and underlie the training proposals, yet without undermining the specific competences. The importance acquired by what workers themselves have considered about their positioning is understood from the standpoint of its validity, so as to assume conclusions through triangulation processes. 相似文献
