In this paper, social network analysis techniques and regression models are used to explain the impact of the level of knowledge development on ego-network redundancy in a community of hospital physicians. Our findings document that the level of knowledge development and the extent to which knowledge is homogeneously distributed amongst collaborating physicians are related to the redundancy of their advice networks, albeit with opposite effects. Our results highlight also that the impact of these relationships on network redundancy is moderated based on whether partnering individuals belong to different professional groups. Our results provide valuable input for the management of knowledge networks within professional organizations. 相似文献

The aim of this work was to study the effect of boot stiffness on the field and laboratory flexural behavior of alpine ski boots. Ski boots have a direct influence on performance, safety, and comfort of alpine skiers. Despite their technological evolution during a number of years, the parameters used in the evaluation of boot stiffness are not yet standardized and still require a shared engineering approach to achieve common quantitative definitions to be used either in boot classification or in boot selection for the different users. This work reports the boot flexion angles between shell and cuff and between cuff and tibia, collected during slalom tests on three boots with different nominal Flex Index. The laboratory data collected on the same boots under conventional cyclic bending tests are reported and compared with the field data for the development of a new test method more representative of the field behavior. As a result, clear definitions of Flex Index and of boot stiffness are introduced: boot stiffness had a clear effect on both the field and the laboratory flexural behavior of boots. 相似文献

Universities need to maintain data about various resources. They include intellectual creations that are the focus of (Digital) Libraries, but also courses, research projects, and people. Data about intellectual creations are maintained in institutional repositories, while data about courses, research projects, and people reside in various databases designed to support specific vertical applications. We propose a uniform treatment of such resources leading to Digital Universities, i.e., a set of key resources, methodologies, and tools appropriately organized to effectively support universities' users. This requires new methodologies, data models, authority control mechanisms, and system infrastructures that are able to support a broader range of services. 相似文献

Firstly, inspired by Le Goff and Truong (Une histoire du corps au Moyen Âge), Richard Sennett (Flesh and Stone) and Michel Maffesoli (Le Rythme de Vie), we have outlined some considerations for the organization of the history of the body in Brazilian football. In the second topic, we review studies that examine the convergence between football and advertising. This theoretical background will link to the subsequent analysis of 11 advertisements of well-known brands in which Brazilian football athlete, Neymar, appears as the poster boy. It is said that in football, especially in the first half of the twentieth century, there was certain prejudice against blacks and biracial players (until today Europe reports cases of racism); in advertising, these groups were kept from certain positions also. In short, Neymar takes part in a scenario of identity crisis as an icon able to instigate criticism as well as praise. His public image is permeated by the youthful desire to see himself represented. 相似文献

Feature-rich data, such as audio-video recordings, digital images, and results of scientific experiments, nowadays constitute the largest fraction of the massive data sets produced daily in the e-society. Content-based similarity search systems working on such data collections are rapidly growing in importance. Unfortunately, similarity search is in general very expensive and hardly scalable. 相似文献
