The purpose of the present study was to empirically examine the link between practicum-related stressors, perceived general practicum stress, personal variables (i.e. general and teaching self-efficacy, epistemological beliefs, conceptions about teaching and learning, and trait anxiety) and burnout dimensions in a sample of 174 Greek student teachers, immediately after the completion of their practicum. In addition, the study sought to identify the best predictive combination of the studied variables for each burnout dimension. Participants who reported high general practicum stress indicated moderate levels of emotional exhaustion, but low depersonalisation and high personal accomplishment. Statistically significant correlates of burnout dimensions were used in three regression analyses. Results revealed that emotional exhaustion and personal accomplishment were predicted by practicum workload, whereas depersonalisation was predicted by teachers’ epistemological beliefs (i.e. learning process) and practicum-related stressors (i.e. meeting pupils’ needs). The present study contributes to the limited body of existing evidence on burnout in student teachers. The results are discussed in terms of both theoretical and practical implications. 相似文献

Abstract This article examines the state of management in Convergence today and poses questions and potential answers for overcoming cultural problems that exist between newspaper and television newsrooms. The article scrutinizes the seeming abyss between these expected media partners and examines cultural implications through literature in organizational psychology, organizational communications and general business management practices. 相似文献

Underfat individuals have been neglected as a malnourished population in terms of redox homeostasis. The aim of the present study was to evaluate the effect of body composition on redox homeostasis at rest and in response to exercise. Underfat, lean and overfat women, classified according to their BMI and body fat percentage, participated in the study and were subjected to an acute session of eccentric exercise. With regard to muscle function and damage, a significant group × time interaction was found for range of motion (P < .01), isometric peak torque at 90° (P < .01), delayed onset muscle soreness (P < .01) and creatine kinase (P < .05), with the lean group generally exhibiting faster recovery compared to the underfat and overfat groups. With regard to redox homeostasis, a significant group × time interaction was found for F2-isoprostanes, protein carbonyls and glutathione (P < .01 for all biomarkers), with the underfat and overfat groups exhibiting increased resting oxidative stress levels and lower exercise-induced reactive species production . In conclusively, our data underline the importance of normal body composition for redox homeostasis, since underfat and overfat women demonstrate a similar pattern of redox disturbances both at rest and in response to exercise. 相似文献

Nowadays, Academic libraries are required to provide high quality services despite their limited budget. Library managers should rely on valid information to keep the library's activities, resources and costs under control. In this paper, we present a case study implementation of Time-Driven Activity-Based Costing (TDABC) at the library of the University of Macedonia, Thessaloniki, Greece. The TDABC is a reliable accounting method that considers many aspects that may affect the employees' efficiency and performance. We adopted quantitative and qualitative methods to evaluate the library's loan and return processes. In particular, we: i) analyzed cost data, ii) interviewed the library's staff, and iii) recorded the duration for all relevant activities with a stopwatch. The activities' duration was recorded via direct observation. The data were collected during the academic year 2017–2018 to cover all the different academic periods. According to our results, the automation of repetitive processes in the circulation department may decrease significantly the operating costs. This may be achieved by reducing the number of staff and replacing them by robotic services. Implementing TDABC in the lending and return processes helped the library managers to determine which activities demand more time and are costly, and to analyze their respective causes. 相似文献

Thirteen autistic teens, who were predominantly Latinx, completed the Program for the Education and Enrichment of Relational Skills (PEERS), a 16-week social skills intervention. Time-frequency decomposition was calculated using advanced electroencephalographic techniques to measure oscillatory brain activity during reward anticipation and processing before and after PEERS. Fourteen neurotypical teens participated but did not receive intervention. The perception of educational performance was also measured. The perception of educational performance did not differ between groups and did not change after participation in PEERS. Approach motivation increased after intervention in the autistic group. This suggests an enhancement of social motivation after learning social skills in a group composed of a majority of Latinx autistic teens. 相似文献

Context has a considerable effect on the role and responsibilities of school principals. The aim of this paper is to provide a holistic perspective of the effects of school principals’ involvement in two low performing schools with different contexts. A qualitative research approach was employed, with individual and focus groups interviews under a multi-actor perspective. Our results suggest that school leaders differ in the way they relate to the inner and outer environment of the school. We suggest that they have to acquire new skills that address entrepreneurial as well as pedagogical tasks, thus exercising edupreneurial leadership. 相似文献

The Stressors about Practicum Inventory, a self-report measure of perceived stressors about the practicum, was designed to provide those responsible for the training of primary school teachers with an informative, inexpensive and psychometrically sound tool. The present study describes the development and validation of the 94-item inventory in a sample of 138 Greek primary student teachers. It also investigates its initial factor structure and reliability. The scale was administered both before and after a four-week period of practicum. Content validity was examined using a panel of experts and student teachers, whereas convergent validity was assessed with the use of a measure of neuroticism. Factor analyses revealed four sources of perceived stress. No gender differences were found. However, the experience of the practicum significantly reduced student teachers’ perceived stress. All perceived stressors were moderately correlated with neuroticism, but after the practicum the size of the correlations was reduced. 相似文献

The ability to learn from expectations is foundational to social and nonsocial learning in children. However, we know little about the brain basis of reward expectation in development. Here, 3- to 4-year-olds (N = 26) were shown a passive associative learning paradigm with dynamic stimuli. Anticipation for reward-related stimuli was measured via the stimulus preceding negativity (SPN). To our knowledge, this is the first study to measure an SPN in children younger than age 6. Our findings reveal distinct anticipatory neural signatures for social versus nonsocial stimuli, consistent with previous research in older children. This study suggests an SPN can be elicited in preschoolers and is larger for social than nonsocial stimuli. 相似文献

Tooth morphology has a pivotal role in the dental curriculum and provides one of the important foundations of clinical practice. To supplement tooth morphology teaching a three-dimensional (3D) quiz application (app) was developed. The 3D resource enables students to study tooth morphology actively by selecting teeth from an interactive quiz, modify their viewpoint and level of zoom. Additionally, students are able to rotate the tooth to obtain a 3D spatial understanding of the different surfaces of the tooth. A cross-over study was designed to allow comparison of students’ results after studying with the new application or traditionally with extracted/model teeth. Data show that the app provides an efficient learning tool and that students’ scores improve with usage (18% increase over three weeks, P < 0.001). Data also show that student assessment scores were correlated with scores obtained while using the app but were not influenced by the teaching modality initially accessed (r2 = 0.175, P < 0.01). Comparison of the 2016 and 2017 class performance shows that the class that had access to the app performed significantly better on their final tooth morphology assessment (68.0% ±15.0 vs. 75.3% ±13.4, P < 0.01). Furthermore, students reported that the 3D application was intuitive, provided useful feedback, presented the key features of the teeth, and assisted in learning tooth morphology. The 3D tooth morphology app thus provides students with a useful adjunct teaching tool for learning dental anatomy. Anat Sci Educ 00: 000–000. © 2018 American Association of Anatomists. 相似文献
