Cross-sectional analysis of rowing power and technique of German junior women in the eight

Since ten years, the German Rowing Federation (DRV) annually conducted 2000-m-race-tests with the best-performing athletes at the beginning of the immediate-pre-competition-preparation (IPCP) for the World-Rowing-Junior-Championships (WRJC). According to previous findings, differences between year-groups, correlations between anthropometric-data, rowing-power and technique development were tested to identify trends and to define a performance-strategy. Twenty test-runs of the junior-women’s-Eight (N=156) were studied using a mobile-measuring-system that records rowing-force and rowing-angle. Body height, body mass, average handle-power with its components handle-force, velocity and handle-displacement per stroke and further rowing-technical characteristics of the rowing-stroke-length were considered and WRJC-race-times used as external-criteria. Single-factor-variance-analysis, linear-correlation, regression-analysis and cluster-analysis were calculated. Significant differences were found between year-groups in body height, body mass and in characteristic values for rowing-power and technique and significant correlations between body height and body mass with rowing-power. Further, six performance-groups were identified by rowing-technique-data. Significant reduction was found in crew’s WRJC-race-time, reflected in handle-power and its determinants. Cross-sectional-comparison showed significant increase in average handle-power and handle-force per rowing-stroke at higher stroke frequency. Based on the cross-sectional-data, selection and year-group influences, together with exercise-induced-effects, should be considered as causes. Results show a functioning preparation-system within the DRV for better prepared-junior-athletes to commence the IPCP

Inducing behavioural change in society through communication and education in sustainable manufacturing

The United Nations considers the mobilization of the broad public to be the essential requirement for achieving a shift towards a more sustainable development. Science can play a vital role in Education for Sustainable Development (ESD) by contributing to ESD-related research and development on the one hand, and by becoming active awareness raisers themselves in education and multiplier networks. Specifically, the use of special Learnstruments, and investment inOpen Educationformats among other educational tools, may pave the way for accelerated apprehension and appreciation of sustainable manufacturing topics among the greater populace

The acquisition of derivational morphology: a cross-linguistic perspective Language acquisition & language disorders ;, v. 66./ edited by Veronika Mattes, Sabine Sommer-Lolei, Katharina Korecky-Kröll, Wolfgang U. Dressler.

Includes bibliographical references and index."This book offers the first systematic study of the early phases in the acquisition of derivational morphology from a cross-linguistic and typological perspective. It presents ten empirical longitudinal studies in genealogically and typologically diverse languages (Indo-European, Finno-Ugric, Altaic) with different degrees of derivational complexity. Data collection, analysis and systematic comparison between child speech and parental child-directed speech are strictly parallel across the chapters. In order to identify the productivity of a derivational pattern, signalling the crucial developmental stage in its acquisition, the concept of the mini-paradigm criterion was applied. Similar developmental processes can be observed in all children, independent of the language they acquire, but the children's courses of development also show obvious typological differences. This points towards an important impact of the structural properties of the specific language on emergence, use and the early course of development of derivational patterns"--1 online resource
