Narrating Your Work: an approach to supporting knowledge sharing in virtual teams     

Anoush?MargaryanEmail author  Eleni?Boursinou  Dane?Lukic  Hans de?Zwart 《知识管理研究与实践》2015,13(4):391-400

We propose an approach to enhancing knowledge sharing and connectedness in distributed teams. Termed ‘Narrating Your Work’ (NYW), the approach involves members of distributed team using a microblogging tool to post regular updates about their current work, accomplishments, and issues. The NYW approach was evaluated within a geographically and temporally distributed team at Shell International for a period of one month, using a mixed-method research design. Methodology comprised of a quantitative survey, followed by semi-structured interviews and analysis of microblogging updates posted during the month in which the approach was being trialled. The evaluation results suggest that NYW was viewed as a valid and practical approach to enhancing knowledge sharing and connectedness. A range of barriers and enablers that could impact the future application and embedding of the approach are identified and recommendations for implementation are outlined.  相似文献   

Droplet formation and shrinking in aqueous two-phase systems using a membrane emulsification method     

Hans Breisig  Matthias Wessling 《Biomicrofluidics》2015,9(4)

Using a membrane emulsification method based on porous hollow-fiber membranes in combination with an aqueous two-phase system (ATPS), we are able to produce “water-in-water” droplets with narrow-dispersed size distributions. The equilibrium phases of the aqueous two-phase system polyethylene glycol-dipotassium hydrogen phosphate are used for this purpose. The droplet diameter of a given fluid system is determined by the flow rates of the continuous and disperse phase as well as the hollow fiber dimensions. When diluting the disperse phase and thus moving the ATPS system out of equilibrium, the droplet size can be further reduced in comparison to the equilibrium case. Generally, droplets formed with this method have diameters 20%–60% larger than the inner hollow fiber diameter. The new strategy of diluting the disperse phase allows the production of droplet diameter below the inner diameter of the membrane.  相似文献   

Struggling with Science and Status: Physiotherapy – Including Radiology and Cancer Treatment – and Physical Education at the State University in Ghent,Belgium, 1906–1936     

Pascal Delheye  Hans Vangrunderbeek 《国际体育史杂志》2015,32(6):815-831

The establishment of new academic specialties is an intriguing research topic from a social history of science perspective. In this article we focus on the ‘scientific migration’ within the Higher Institute of Physical Education (HIPE) and the Faculty of Medicine at the State University in Ghent, Belgium. The HIPE was ‘attached’ to the Faculty of Medicine in 1908, a world first that led to an interesting triangular relationship between physical education, physiotherapy, and medicine. The physiatrists (physicians-physiotherapists) who were appointed at the HIPE had to struggle with inferior status with respect to their colleagues within the Faculty of Medicine itself. Territorial power struggles arose on several levels. In 1936, after the first generation of physicians-physiotherapists had retired, physiotherapy was integrated fully into the Faculty of Medicine, and radiology and cancer treatment – which had been considered subsectors of physiotherapy – became autonomous specialties. Physical education, however, retained its inferior academic status.  相似文献

Curriculum Reform and the Legitimation of Educational Objectives: the case of the Federal Republic of Germany     

Hans N. Weiler 《牛津教育评论》2013,39(1):15-27

Abstract

Taking the political and scholarly debates about curriculum reform in the Federal Republic of Germany as a case in point, the article develops the notion of ‘compensatory legitimation’ as a theoretical construct for better understanding the political dynamics of making and implementing educational policy under conditions of conflict. Among various strategies of compensatory legitimation, special attention is given to the recourse to legal and constitutional norms, the utilisation of expertise, and the invocation of the discourse of participation.
