Far from Fifty-Fifty: Legal Measures and the Relative Lack of Women in Powerful Decision-Making Positions in Germany’s Broadcasting Sector     

Romy Fröhlich  Sabine Baudisch 《广播与电子媒介杂志》2016,60(2):305-330

A gender-equal organization of institutions requires adequately qualified women to be equally present on every hierarchical/functional level. In light of this, the authors evaluate how women participate in leading managerial and supervisory positions of administrative relevance, i.e., beyond editorial departments, in public and private broadcasting corporations and organizations in Germany. The study comprises an examination and comparison of existing legal requirements/regulations for gender equality on the supervisory councils of Germany’s broadcasting corporations/organizations and contributes to the analysis on the contemporary politics of gender in Germany’s broadcasting sector. It is the first study of its kind.  相似文献

Perspectives on using video recordings in conversation analytical studies on learning in interaction     

Fredrik Rusk  Michaela Pörn  Fritjof Sahlström  Anna Slotte-Lüttge 《International Journal of Research & Method in Education》2015,38(1):39-55

Video is currently used in many studies to document the interaction in conversation analytical (CA) studies on learning. The discussion on the method used in these studies has primarily focused on the analysis or the data construction, whereas the relation between data construction and analysis is rarely brought to attention. The aim of this article is to discuss different approaches to data construction that CA studies in and on learning utilize, and how these approaches facilitate different analysis and understandings of learning and cognition from emic, participants', points of view. Three, partly overlapping, thematic approaches can be discerned: (1) setting-centred, (2) participant-centred and (3) content-centred. The underlying interest of the study seems to influence the data construction, which in turn affects what kind of analysis that can be done. There is a considerable variation in which aspects data sets focus on, where an emphasis in data construction on setting, participant or content also seems to project the subsequent analytic emphasis. This relation between data construction and analysis is important to be aware of and to address.  相似文献   

Training on the project: a quantifying approach to competence development     

Christian?Stummer  Walter J?Gutjahr  Michaela?Denk  Harald?Riedmann  Karl A?FroeschlEmail author 《知识管理研究与实践》2012,10(1):64-78

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

Kinematic analysis of the double side kick in pointfighting,kickboxing     

Dominik Hölbling  Emanuel Preuschl  Michaela Hassmann  Arnold Baca 《Journal of sports sciences》2017,35(4):317-324

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   

Combinations of Epoch Durations and Cut-Points to Estimate Sedentary Time and Physical Activity Among Adolescents     

Andreas Fröberg  Christina Berg  Christel Larsson  Cecilia Boldemann  Anders Raustorp 《Measurement in physical education and exercise science》2017,21(3):154-160

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended.  相似文献
