Media and Occupational Aspirations: The Effect of Television on Career Aspirations of Adolescents     

Volker Gehrau  Tim Brüggemann  Jutta Handrup 《广播与电子媒介杂志》2016,60(3):465-483

Vocational decisions are important decisions for adolescents. This article takes television effects into account. A literature review for the occupational world in TV programs reveals a strong focus on some occupations as well as small cultivation effects plus learning effects from mediated role models. A secondary analysis of 2 panel waves was undertaken to study the effect of media role models on occupational aspiration. Television usage in a program segment correlated with corresponding aspirations. A process models showed a strong effect of career aspiration in 1 panel wave on related television usage and career aspirations in the following panel wave.  相似文献   

Experiencing Exhibitions: A Review of Studies on Visitor Experiences in Museums     

Volker Kirchberg  Martin Trndle 《Curator: The Museum Journal》2012,55(4):435-452

Abstract This article reviews empirically oriented studies from the United States and Europe concerning visitor experiences in museum exhibitions in order to pinpoint similarities and differences among them. In the last 20 years, only a few scholars have tackled this research question in multifaceted empirical ways, although some of them have done so extensively. By comparing theoretical and methodical issues, as well as important results, we are able to outline several analytical building blocks that compose a complex framework of visitor expectations, experiences, and outcomes. Gathering credible data on experiences of visitors in exhibitions or museums, a method dating back to the tracking records of Robinson (1928) , is an ongoing challenge for the empirically inclined science of museum studies. Social scientists at universities and museums have been asking for 20 years: What are the findings regarding factors, structures, and consequences of exhibition experiences? Where are the blind spots? Which questions should be researched?  相似文献   

Modelling the deflection of rowing oar shafts     

Brock Laschowski  Cameron C. Hopkins  John R. de Bruyn  Volker Nolte 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):76-86

The deflection of rowing oar shafts subjected to a static load was investigated. Two sets of sculling oars of different design stiffness were tested at three different lengths from 2.66 to 2.70 m. Loads up to 201 N were applied to the blade end of the oar shafts, and deflections were measured at six positions along the length of the shafts. The experimental results were compared with theoretical predictions obtained by modelling the oar shafts as homogenous end-loaded cantilever beams. The results show that the oar shafts are not uniform, in contradiction to the assumed model, but rather are most compliant near the sleeves and up to 80% stiffer towards the blades. The effect of oar shaft stiffness and length on the deflection angle at the blade end of the oar shaft was at most 1.18 ± 0.01°. The measured variation of stiffness along the shaft has implications for boat propulsion and rowing performance.  相似文献
