In the project ‘Competence-Driven Project Portfolio Analysis’ (CDPPA), an integrated system for supporting R&D project selection, staff assignment and activity scheduling with special consideration of the strategic development of competencies has been designed and implemented prototypically. The system has been field-tested at the Electronic Commerce Competence Center (EC3), a public–private partnership R&D enterprise. Experiences from this trial application are summarised and discussed, particularly concerning data collection and competence measurement, the benefits and limits of the chosen multi-criteria decision analysis approach, the evaluation of introduced changes to the decision-making processes, and the transparency of the formal planning model and its components.  相似文献

The double side kick is a frequently used technique in pointfighting on which most offensive kicking techniques are based on. The aim of the study was to identify parameters, e.g., trunk and leg positions, durations and velocities that affect successful technique execution.

44 fighters, male and female, including European and World champions, participated in the research. The participants performed double side kicks to a punching bag with the target at chest level. 10 international experts scored (1–10 points; interrater correlation ICC (3,1): 0.952) videos of the best individual trial for quality of technique execution. Based on the average of the scores participants were categorised into 2 equally sized groups. For kinematic data acquisition, a Vicon 3D-motion capturing system was used. The normalised knee height of the kick leg (KHK), normalised absolute distance to the frontal shoulder (DKS) at the end of both chambering phases, the horizontal velocity during both chambering phases (KEV), the durations of all 6 functional phases and total duration, were analysed.

KHK1, KHK2, DKS1 and DKS2, total duration as well as 4 out of 6 phase durations and KEV1 showed significant differences between groups in two-sided t-test or Mann–Whitney U-test for not normally distributed variables.  相似文献

Valid and reliable standardized assessment of nursing competencies is needed to monitor the quality of vocational education and training (VET) in nursing and evaluate learning outcomes for care work trainees with increasingly heterogeneous learning backgrounds. To date, however, the modeling of professional competencies has not yet evolved into procedures that would meet large-scale assessment (LSA) standards in VET. To empirically test a proposed structural model for client-directed nursing competence and to estimate psychometric properties of a newly developed video- and computer-based test (CBT) to inform subsequent LSA in nursing VET, 402 final-year nursing students from 24 German schools responded to a 77 item CBT. Multi-dimensional IRT modeling was employed to test the subdomain structure and estimate students’ competencies in geriatric nursing. The standardized CBT measures nursing students’ client-directed care competence with acceptable precision (WLE?=?0.76) and does so across the whole range of observed proficiency levels. Structural validity was supported by substantive contributions of test items from all proposed process-oriented subdomains, practice field scenarios, as well as items with and without reference to emotional demands. However, it was not possible to empirically separate the diagnostic, practical or communicative subdomains, probably reflecting parallel, recursive and hierarchical care processes in complex care situations. On average, students in our sample attained 45 % of the maximum test score so it is a demanding assessment of nursing competence. An extensively piloted, valid and reliable CBT is suggested to assess nursing students’ client-directed care competencies at the end of the third year of the VET program.  相似文献

Based on self-determination theory, this study seeks to explore whether a study environment that provides relevant conditions for students’ basic psychological need-satisfaction can lead to more positive and less negative emotional experiences. It also addresses the question of how emotions experienced in the university context are related to students’ overall life-satisfaction and study commitment. German students in teacher education programmes (N = 792) participated in the study by completing questionnaires. The results (estimated by path-modelling) reveal that students’ emotions can be predicted by a variety of environmental conditions associated with different basic psychological needs. Altogether, the model is able to explain 28.5% of the variance in positive emotions and 39.6% in negative emotions. The strongest predictor of students’ positive and negative emotions was the perceived relevance of the study material, a factor related to the need for autonomy. This perceived relevance also had a direct impact on study commitment. Furthermore, positive relationships with peers proved to be of importance for positive and negative emotions as well as for overall life-satisfaction. As expected, emotions at university predicted life-satisfaction and study commitment, with a particularly strong association between positive emotions and study commitment. The results point to the necessity to support study conditions that facilitate the fulfilment of students’ basic psychological needs in order to ensure students’ emotional well-being and enhance study commitment.  相似文献

As a consequence of international educational studies like TIMSS and PISA, quality of instruction has become a central topic in the discussion between educators, researchers, and policymakers. Teacher competencies are preconditions for instructional quality.This study focuses on the impact of perceived teacher competencies on student well-being and anxiety in physics instruction. Student emotions are one important aspect of the educational process and supposed preconditions of sustainable learning processes. In the study, we combine both qualitative and quantitative methods using questionnaires and semi-structured interviews. In total, 431 students from 16 classes participated in this study: 24 students and eight physics teachers were participants of the qualitative study. Each teacher taught two classes, and therefore a comparison of the ratings of each teacher by students of two different classes was possible.The results of our study confirm the assumption that perceived teacher competencies have an impact on student emotions. Analysis of the qualitative data supports the quantitative results and demonstrates the importance of teacher competencies for student emotions. By comparing qualitative and quantitative results, we demonstrate the advantages and disadvantages of each method. Consequently, we suggest a combination of qualitative and quantitative methods.  相似文献

This research examined what university students recommend for effective university study and whether their recommendations differ by gender, faculty or study programme degree. The research was based on 985 questionnaires. The following words were most commonly used in advice for freshmen: Go, Lectures, Learn, Continuously, Be, Prepare, Information, Have, Do, Materials. The fundamental advice seems to be: to go to lectures, to have needed materials and information and to learn and prepare continuously. Some stated recommendations react to the development of information and communication technologies and the massive usage of the Internet (such as obtaining a laptop and a cell phone or setting up a Facebook profile). Quite a lot of advice was connected with health, such as to sleep enough, to eat regularly, to not smoke, to relax and to restrict alcohol consumption. The recommendations gained in this survey were categorised by thematic similarities to characteristics, knowledge, skills, behaviour and background. The findings highlight the fact that given recommendations for effective study differ by the respondent’s gender and faculty. Women concentrated more on recommendations on how to behave and men mentioned more often what personality characteristics are important for effective university study. Students of the Faculty of Multimedia Communications highlighted the necessity of creativity and practical experience more often than others.  相似文献

This paper provides a general overview of the way local governments use Twitter as a communication tool to engage with their citizens. More concretely, it tries to identify factors associated with both the channel activity and citizen engagement, to understand the relationship between media type and citizen engagement and to analyse whether different content generated different levels of engagement. A sample of the 29 most populated Andalusian local governments is examined. The results show that the majority of Andalusian local governments have an official corporate Twitter account with certain level of activity. There is no, however, a significant relationship between the population of a municipality and its citizen's engagement, and there is a significant negative relationship between audience and engagement and between activity and engagement. The findings of the study also show the particular media and content types generate higher engagement than others. This paper contributes to the literature on social media and has practical implications for local governments.  相似文献
