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

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

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

Abstract This study examined salivary cortisol and testosterone responses to two, different high-intensity, ～30-min cycles separated by 2 h rest before and after an 11-day intensified training period. Twelve recreationally active, healthy males completed the study. Saliva samples were collected before, immediately after and 30 min after both bouts with salivary cortisol and testosterone concentrations assessed. Compared with pre-training blunted exercise-induced salivary cortisol, testosterone and cortisol/testosterone responses to both bouts post-training were observed (P < 0.05 for all). Comparing pre- with post-training the absolute exercise-induced salivary cortisol, testosterone and cortisol/testosterone decreased from 11.1 to 3.1 and 7.0 to 4.4 nmol · L?1 (cortisol), from 407 to 258 and from 473 to 274 pmol · L?1 (testosterone) and from 12 to 4 and 7 to 5 (cortisol/testosterone) for the first and second bouts, respectively (P < 0.05). No differences in the pre- and post-training rating of perceived exertion (RPE) and heart rate (HR) responses during the cycles or times to fatigue were found (P > 0.05). Fatigue and Burnout scores were higher post- compared with pre-training (P < 0.05). These high-intensity exercise bouts can detect altered hormonal responses following intensified training. This test could assess an athlete's current hormonal status, reductions in salivary cortisol and testosterone responses suggestive of increased fatigue. 相似文献
