Teaching requires much emotion work which takes its toll on teachers. Emotion work is usually studied from one of two perspectives, a job or an individual perspective. In this study, we assessed the relative importance of these two perspectives in predicting emotional exhaustion. More than 200 teachers completed a questionnaire comprising the DISQ (Demand‐Induced Strain Compensation Questionnaire), the Dutch Questionnaire on Emotional Labour (D‐QEL), and the UBOS (Utrechtse Burnout Schaal [Utrecht Burnout Scale]). In line with previous studies, our findings indicated that emotional exhaustion is positively associated with emotional job demands and surface acting. The relative importance of the two operationalisations of emotion work was assessed by comparing the results of two regression analyses. Whereas the model with job demands explained 18% of the variance, the model with emotional labour explained only 5%. In understanding what might contribute to emotional exhaustion in teachers, the emotional job demands might be much more important than the self‐regulation perspective that is measured with emotional labour. 相似文献

A library service model that provides reference and instructional services by summoning reference librarians from a single service point is described. The system utilizes Libraryh3lp, an open-source, multioperator instant messaging system. The selection and refinement of this solution and technical challenges encountered are explored, as is the design of public services around this technology, usage of the system, and best practices. This service model, while a major cultural and procedural change at first, is now a routine aspect of customer service for this library. 相似文献

The aims of the present study were (1) to analyse the physical demands of top-class referees and (2) to compare their official FIFA fitness test results with physical performance during a match. The work rate profiles of 11 international referees were assessed during 12 competitive matches at the 2003 FIFA Under-17 World Cup and then analysed using a bi-dimensional photogrammetric video analysis system based on direct lineal transformation (DLT) algorithms. In the first 15 min of matches, the referees were more active, performing more high-intensity exercise (P < 0.01) than in the first 15 min of the second half. During the second half of matches, the referees covered a shorter distance (P < 0.01), spent more time standing still (P < 0.05), and covered less ground cruising (P < 0.05), sprinting (P < 0.05), and moving backwards (P < 0.001) than in the first half. Also in the second 45 min, the distance of referees from infringements increased (P < 0.05) in the left attacking zone of the filed. There was also a decrease (P < 0.05) in performance in the period following the most high-intensity activity, compared with the mean for the 90 min. Time spent performing high-intensity activities during a match was not related to performance in the 12-min run (r(2) = 0.30; P < 0.05), the 200-m sprint (r(2) = 0.05; P < 0.05), or the 50-m sprint (r(2) = 0.001; P < 0.05). The results of this study show that: (1) top-class referees experienced fatigue at different stages of the match, and (2) the typical field tests used by FIFA (two 50-m and 200-m sprints, followed by a 12-min run) are not correlated with match activities. 相似文献

Many higher educational institutions and academic staff are still sceptical about the validity and reliability of student evaluation questionnaires, in particular when these evaluations are completed online. One month after a university-wide implementation from paper to online evaluation across 629 modules, (perceived) resistance and ambivalence amongst academic staff were unpacked. A mixed-method study was conducted amongst 104 academics using survey methods and follow-up semi-structured interviews. Despite a successful ‘technical’ transition (i.e. response rate of 60%, similar scores to previous evaluations), more than half of respondents reported a negative experience with this transition. The results indicate that the multidimensional nature of ambivalence towards change and the dual nature of student evaluations can influence the effectiveness of organisational transition processes. 相似文献

This paper examines the relationship between (outside-in) open innovation and the financial performance of R&D projects, drawing on a unique dataset that contains information on the open innovation practices, management and performance of 489 R&D projects of a large European multinational firm. We introduce two types of open innovation partnerships – science-based and market-based partnerships – and examine their relationships with project financial performance. In addition, we investigate whether the open innovation—project performance relationships are influenced by the way how R&D projects are managed. Our results show that R&D projects with open innovation partnerships are associated with a better financial performance providing that they are managed in the most suitable way. Market-based partnerships are positively correlated with project performance if a formal project management process is used; however these partnerships are associated with a lower performance for loosely managed projects. In contrast, science-based partnerships are associated with higher project revenues for loosely managed projects only. 相似文献

This paper examines the impact of universities on the technological performance of adjacent firms. We extend existing research by jointly analyzing, and comparing, the effects of education (graduates) and scientific research (publications) activities of universities on firms’ technological performance. Adopting the knowledge production framework, our study is conducted at the level of 101 Italian territorial areas (provinces) and four industries. Overall, fixed-effect panel data models reveal a positive effect of both university graduates and scientific publications on the technological performance of firms. At the same time, considerable industry differences are observed. While the provision of university graduates positively affects firm performance in all industries under study, additional effects for scientific research are only observed in electrical and pharmaceutical industries that are science-intensive and where the scientific knowledge base is changing rapidly over time. The observation that spillovers from academia into the industrial texture of provinces rely on education and research in an industry-specific manner is relevant to the design of appropriate research and innovation policies. 相似文献

A common assumption in higher education is that international students find it difficult to develop learning and friendship relations with host students. When students are placed in a student-centred environment, international students from different cultural backgrounds are “forced” to work together with other students, which allows students to learn from different perspectives. However, large lecture rooms may provide fewer opportunities for students to work together in small groups. The purpose of this article is to understand how 191 international students from 34 cultural backgrounds and 16 host students build learning and friendship relations in a large classroom of 207 students. We have used an innovative mixed-method design of social network analysis in a pre- and post-test manner combined with two sets of focus groups. Using multiple regression quadratic assignment procedures, the results indicate that learning ties after 11 weeks were significantly predicted by the friendship and learning ties established at the beginning of the module, (sub)specialisation, and whether students were Chinese or not. Contrary to previous findings, team divisions played only a marginal role in building (new) learning relations. A substantial segregation between Confucian Asian, European international and UK students was present. Follow-up qualitative data highlighted that international students made a conscious effort to build friendship and learning relations primarily outside the formal team, which for some were along co-national lines, while others were pro-actively looking for new perspectives from multi-national students. These results indicate that the instructional design might have a strong influence on how international and host students work and learn together. We believe that this study is the first to provide an in-depth and unique understanding of how international students from different cultural backgrounds build friendship and learning-relationships with other students in- and outside their classroom over time in a large classroom of 200+ students. 相似文献

PurposeThe aim of this study was to review information about risk factors for lower extremity running injuries in both short-distance (mean running distance ≤20 km/week and ≤10 km/session) and long-distance runners (mean running distance >20 km/week and >10 km/session).MethodsElectronic databases were searched for articles published up to February 2019. Prospective cohort studies using multivariable analysis for the assessment of individual risk factors or risk models for the occurrence of lower extremity running injuries were included. Two reviewers independently selected studies for eligibility and assessed risk of bias with the Quality in Prognostic Studies Tool. The GRADE approach was used to assess the quality of the evidence.ResultsA total of 29 studies were included: 17 studies focused on short-distance runners, 11 studies focused on long-distance runners, and 1 study focused on both types of runners. A previous running-related injury was the strongest risk factor for an injury for long-distance runners, with moderate-quality evidence. Previous injuries not attributed to running was the strongest risk factor for an injury for short-distance runners, with high-quality evidence. Higher body mass index, higher age, sex (male), having no previous running experience, and lower running volume were strong risk factors, with moderate quality evidence, for short-distance runners. Low-quality evidence was found for all risk models as predictors of running-related injuries among short- and long-distance runners.ConclusionSeveral risk factors for lower extremity injuries have been identified among short- and long-distance runners, but the quality of evidence for these risk factors for running-related injuries is limited. Running injuries seem to have a multifactorial origin both in short- and long-distance runners. 相似文献

One-hundred-six 5-year-olds’ (Mage = 5;6; SD = 0.40) were trained with second-order false belief tasks in one of the following conditions: (a) feedback with explanation; (b) feedback without explanation; (c) no feedback; (d) active control. The results showed that there were significant improvements in children's scores from pretest to posttest in the three experimental conditions even when children's age, verbal abilities, or working memory scores were controlled for. The training effect was stable at a follow-up session 4 months after the pretest. Overall, our results suggest that 5-year-olds’ failures in second-order false belief tasks are due to lack of experience and that they can be helped over the threshold by exposure to many stories involving second-order false belief reasoning, including why questions. 相似文献
