Universities must adapt to the challenges of social competitiveness and its new demands but there is still little evidence of how these changes are perceived by the academics. This paper provides insight on this matter and analyses the research culture of five Spanish universities from the perspective of the different academic bodies. A qualitative methodology was employed in the study based on 43 in-depth interviews with institutional leaders (vice-rectors and managers), responsible for research activity, (directors of research centres) and individual researchers (doctoral and postdoctoral researchers). The results point to a clear change in the institutional mission that moves from an institutional model where teaching and research cohabitate together towards another where research activity intensifies. The manifestations of the new research culture is characterised by the quest for efficiency and competitiveness at all levels and bodies. Despite the changes in the university model, participants perceive that the traditional and new models coexist and affect the university structure, the functioning of the centres and departments and the dynamics of the research teams which causes dissatisfaction of the researchers that in this context have to deal with the increasing pressure to publish and obtain external funding to assure ‘survival’. The research culture is also characterised as one that moves towards the scarcity of support measures for training, the confusion perceived between the political discourse and academic practice and the attempt to reposition the university in a social context, through redefining its role and fostering transfer activities. 相似文献

Academic dishonesty in higher education is an increasingly visible problem throughout the world and in Romania in particular. A total of 1127 university students from six public Romanian universities were surveyed for their experiences and beliefs with 22 behaviors that might be considered academically dishonest. A five-factor solution to the frequencies of these behaviors was interpretable and accounted for more than half of the total variance. How acceptable students believed the behaviors were and how often students witnessed other students engage in these behaviors were consistent predictors of the frequency of the behaviors, with small to medium effect sizes. Demographic predictors of these behaviors, including gender, academic specialty, year in school, institution, grade average, and scholarship status, predicted very little variance in the behaviors. Implications and limitations of the study, as well as limitations of research in the field, are discussed. 相似文献

The use of technology with engineering design students is well established, with shared workspaces being particularly supportive of the collaborative design process. This paper reports on a study where a design knowledge framework involving three learning loops was used to analyse the effectiveness of shared workspaces and digital repositories in supporting design education. The issues discussed include the relationship between knowledge and information structures, the importance of integrating information literacy support, and the need for different systems within the learning environment to support formal and informal storage of resources. These issues are explored within the context of experiences of working in a multidisciplinary team with different approaches, research methodologies, and discourses. 相似文献

This article examines an innovation in teaching-learning and assessment processes through the use of a platform called the Competency Assessment Tool (CAT). It allows for the tracking of student blogs with the objective of improving self-reflective processes and providing feedback. The experiment was carried out in six universities in Catalonia, Spain, and involved seven different subjects. The CAT platform and its features related to the acquisition of competencies are presented, as are users’ opinions on the metacognitive and feedback processes provided by the tool. The methods used were questionnaires received by students and teachers. Results show a high level of satisfaction for all those involved and emphasise that student participation in the assessment process increases their awareness of the teaching-learning process through self-regulation procedures. The most significant result is related to the use of electronic tools as an appraisal instrument and their enhancement of competency-based assessment. 相似文献

Estimates of progression and variability of athletic performance in competitions are useful for researchers and practitioners interested in factors that affect performance. We used repeated-measures mixed modelling to analyse 676 official race times of 26 US and 25 Australian Olympic swimmers in the 12-month period leading up to the 2000 Olympic Games. Progression was expressed as percent changes in mean performance; variability was expressed as the coefficient of variation in performance of an individual swimmer between races. Within competitions, both nations showed similar improvements in mean time from heats through finals (overall 1.2%; 95% confidence limits 1.1 to 1.3%). Mean competition time also improved over 12 months by a similar amount in both nations (0.9%; 95% confidence limits 0.6 to 1.2%). The US swimmers showed a greater improvement between the finals (a difference of 0.5%; 95% confidence limits -0.2 to 1.1%), which paralleled changes in the medal haul of the two nations. The coefficient of variation in performance time for a swimmer between races was 0.60% (95% confidence limits 0.56 to 0.65%) within a competition and 0.80% (95% confidence limits 0.73 to 0.86%) between competitions. Our results show that: (a) to stay in contention for a medal, an Olympic swimmer should improve his or her performance by approximately 1% within a competition and by approximately 1% within the year leading up to the Olympics; (b) an additional enhancement of approximately 0.4% (one-half the between-competition variability) would substantially increase the swimmer's chances of a medal. 相似文献

A Memory-Based Approach to Anti-Spam Filtering for Mailing Lists 总被引：14，自引：0，他引：14

This paper presents an extensive empirical evaluation of memory-based learning in the context of anti-spam filtering, a novel cost-sensitive application of text categorization that attempts to identify automatically unsolicited commercial messages that flood mailboxes. Focusing on anti-spam filtering for mailing lists, a thorough investigation of the effectiveness of a memory-based anti-spam filter is performed using a publicly available corpus. The investigation includes different attribute and distance-weighting schemes, and studies on the effect of the neighborhood size, the size of the attribute set, and the size of the training corpus. Three different cost scenarios are identified, and suitable cost-sensitive evaluation functions are employed. We conclude that memory-based anti-spam filtering for mailing lists is practically feasible, especially when combined with additional safety nets. Compared to a previously tested Naive Bayes filter, the memory-based filter performs on average better, particularly when the misclassification cost for non-spam messages is high. 相似文献
