The recent changes in the relationship between universities and society and the change of attitudes of governments towards higher education institutions are analysed. The different possible reactions of the institutions to the more demanding attitude of society as a whole are discussed. The authors present a critical view of the concept of entrepreneurial universities based on the work of Burton Clark and on the results of the quality audits of the Association of European Universities (CRE), and offer some comments about their applicability and usefulness to European higher education systems.  相似文献

Queries submitted to search engines can be classified according to the user goals into three distinct categories: navigational, informational, and transactional. Such classification may be useful, for instance, as additional information for advertisement selection algorithms and for search engine ranking functions, among other possible applications. This paper presents a study about the impact of using several features extracted from the document collection and query logs on the task of automatically identifying the users’ goals behind their queries. We propose the use of new features not previously reported in literature and study their impact on the quality of the query classification task. Further, we study the impact of each feature on different web collections, showing that the choice of the best set of features may change according to the target collection.  相似文献

The attenuation of an LiCl-induced conditioned taste aversion (CTA) by LiCl preexposure is mediated primarily by associative blocking via injection-related cues. Given that preexposure to morphine attenuates morphine-induced CTAs, it was of interest to determine whether injection cues also mediate this effect. Certain morphine-induced behaviors such as analgesic tolerance are controlled associatively, via injection-related cues. Accordingly, animals in the present experiments were preexposed to morphine (or vehicle) every other day for five total exposures, followed by an extinction phase, in which the subjects were given saline injections (or no treatment) for 8 (Experiment 1) or 16 (Experiment 2) consecutive days. All of the animals then received five CTA trials with morphine (or vehicle). The morphine-preexposed animals in Experiment 1 displayed an attenuation of the morphine CTA that was unaffected by extinction saline injections, suggesting that blocking by injection cues during morphine preexposure does not mediate this effect. All of the morphine-preexposed subjects in Experiment 2 displayed a weakened preexposure effect, an effect inconsistent with a selective extinction of drug-associated stimuli. The attenuating effects of morphine preexposure in aversion learning are most likely controlled by nonassociative mechanisms, like drug tolerance.  相似文献

The aim of this article is to outline and assess an educational intervention programme targeted at improving the skills of families and the personal and social development of children living in situations of grave social vulnerability. The sample comprised 10 families during the first phase of the intervention and six during the second. The design, intervention and assessment process of this study was carried out in two phases over a period of a year and a half. For both phases, three different groups—of men/fathers, women/mothers and children—were established. Study variables (parenting skills and children’s personal and social development) were evaluated before and after the intervention in every group, as well as during the entire process. The results, taking into account the improvements reported by all the participants (social workers, group monitors, fathers, mothers, children) show that inter-professional involvement and coordination at all phases of the intervention is vital in order to achieve small but significant improvements.  相似文献

This paper reports on an investigation carried out in New Zealand into experienced elementary and student teachers’ beliefs about the nature and purpose of social studies education. Since its inclusion in New Zealand's curriculum, social studies has been organized around the notion of citizenship education with curricula and programmes of work influenced by four overarching “traditions” – social studies as: citizenship transmission; social science; reflective inquiry; and personal, social and ethical empowerment. A 20-item scale based on these traditions was administered to 228 student teachers and 64 experienced teachers. A factor analysis indicated that participants' perceptions of the dimensions of social studies education were, with one exception, reasonably close to the four traditions. Despite the contested nature of social studies, the student and experienced teachers held similar positions on the relative importance of the traditions and dimensions. It is argued that this agreement arises, wholly or in part, from their common “apprenticeship of experience” in classrooms, the broader socio-historical context in which their beliefs were developed, the widespread influence of a prevalent educational discourse, and a shared lack of experience in formal knowledge associated with specific social science disciplines. It was concluded that the uncomfortable generational encounters often reported in the literature between novice and experienced teachers are unlikely to occur in relation to the teaching of elementary social studies in New Zealand.  相似文献

The types of difficulties associated with career attitudes were studied using Super’s model of career maturity (1990) in a group of 620 Portuguese students from grades 9 and 12. A cluster analysis identified four styles with different patterns of association between time perspective, attributional beliefs, self-esteem and career attitudes. The adaptive style showed more committed career attitudes, and the other three styles—superficial, insecure and pessimistic—showed lower levels of career maturity. Implications for career counselling are further discussed.  相似文献

Schooling and the knowledge acquired at school have been considered both a cause of loss of indigenous knowledge (because it opens pathways to the non-indigenous world and worldviews) and a potential remedy to its demise (if educational curricula is aligned with indigenous realities by giving instruction in local languages and incorporating local knowledge in school content). We test the association between academic and local environmental knowledge using data from a society of forager-horticulturalists in the Bolivian Amazon who were exposed to a partially contextualized school curriculum. We found that although schooling and academic knowledge bear a negative association with local knowledge the magnitude is low, probably because schooling was partially contextualized. Contextualized learning might help avoid that the provision of universal education comes at the cost of humanity's cultural diversity.  相似文献

The aim of this study was to investigate the work-based internship experiences of eight student-coaches. This was particularly in terms of what precisely such coaches learned within the practical context, and how they engaged with unexpected situational events. The methods employed within the project included focus group interviews and participant observation. In particular, the student-coaches were both interviewed and observed over the course of a nine-month sporting season, with each phase of the research informing the next. The subsequent data were primarily subject to a thematic analysis. The findings of the study were organized under four principal themes: (1) the reality shock felt by the student-coaches in terms of the gap between what they expected and what they experienced; (2) the lack of respect demonstrated by the organizational head coaches for the students; (3) the students’ response in terms of developing their micro-political literacy; and (4) the social price paid by the student-coaches in adopting such action. The results point to the limitations of student learning within high-performance sporting environments. In this respect, the student-coaches’ experiences were not what was expected or desired. Despite this, many valuable and relevant lessons were learned. These related to developing students’ micro-political literacy; necessary knowledge for any neophyte coaches trying to establish bone-fide situational roles.  相似文献

Purpose: The purpose of this study was to provide an integrated analysis of a teacher’s peer-teaching mediation strategies, the student-coaches’ instruction, and the students’ gameplay development across 3 consecutive seasons of sport education. Method: Twenty-six 7th-grade students participated in 3 consecutive sport education seasons of invasion games (basketball, handball, and soccer). The research involved 3 action research cycles, 1 per season, and each cycle included the processes of planning, acting and monitoring, reflecting, and fact finding. Data collection consisted of videotape and audiotape records of all 47 lessons, a reflective field diary kept by the first author in the role of teacher-researcher, and a total of 24 semistructured focus-group interviews. Trustworthiness criteria for assuring the quality of qualitative research included extensive data triangulation, stakeholders’ crosschecking, and collaborative interpretational analysis. Results: Through the application of systematic preparation strategies, student-coaches were able to successfully conduct team instruction that resulted in students’ tactical development and improved performance. Aspects such as the study of predominant configurations of players’ gameplay and similar tactical principles across games within the same category prevented a setback in the complexity of the learning content addressed at the beginning of each season. Players also showed an increasing ability to adapt gameplay to game conditions. Conclusions: While sport education has the capacity to develop competent players, different levels of teacher guidance and learners’ instructional responsibility are necessary when teaching tactics.  相似文献

Artificial rugby union playing surface installation is increasing. This prospective cohort study aimed to examine the effect of playing surface on match injury types within 157 players of two UK professional rugby union clubs playing 209 matches (96 on artificial surfaces and 113 on grass) over three seasons. There was no difference in overall injury risk between the two playing surfaces with injury incidence on artificial 80.2 (CI 69.9–91.7) and on grass 81.9 per 1000 match-hours (CI 72.2–92.5), with an incidence rate ratio (RR) of 0.98 (CI 0.82–1.17). There was a higher rate of concussion (RR 0.52, CI 0.34 – 0.78) and chest injuries on grass (RR 0.26 CI 0.07, 0.95), and a higher rate of thigh haematoma (RR 2.25, CI 1.05–4.82) foot injuries (RR 4.12, CI 1.10, 15.40) and injury to players being tackled (RR 1.46, CI 1.00, 2.15) on artificial. Whilst there was no higher injury risk for matches played on artificial versus natural grass surfaces, the higher incidence of concussion and chest injury on grass, and the higher rate of foot injuries on artificial surfaces may be related to tackle and footwear-to-surface interface factors.  相似文献
