In this paper, we investigate the interplay of clinical knowledge and technological capabilities in the recent development of HIV/AIDS treatments and offer qualitative and quantitative evidence from the empirical setting of Italian practice. The study contributes to the literature on the co-evolution of physical and social technologies in medical innovation by showing how professional guidelines, systematic evaluative research and local coordination mechanisms contribute actively to the resolution of the uncertainty that surrounds technological advances, while leaving room for largely discretional therapeutic choices. The resulting variety in implementation strategies improves health outcomes, but may reduce productive efficiency.  相似文献

This study examined cultural reflections online of audience comments on social network sites regarding vocal talent shows in China and the United States. The study applied dimensions of cross culture to investigate audience comments on the official social networking sites of The Voice of China and The Voice. Findings reflect Hofstede’s dimensions as applied to social media and illustrate how individuals alter their “local” cultural norms in the new media environment. The study specifically enhances the exploration of cultural manifestations in cyberspace, which fewer cross-cultural studies have researched.  相似文献

The vegetative stratum is a layer of existence that is inherent not only in plants. Here, I propose to look at how vegetative life – or, the vegetative mode of existence – affects cities. The vegetative mode of existence is not focused on activities, routines, achievements. Here appears a city that is not industrial or industrious. When the industrious city retreats, or falls apart, the vegetative stratum becomes visible. The vegetative city is a city without any central nervous system. I suggest the interpretation of the vegetative city as a hopeful manifestation of the urban that only takes place when the time is ripe.  相似文献

The development of peak performances is a main research focus in sports science. It is unclear how many former top junior athletes achieve success in the elite class later. The aim of the present study was to examine the careers of athletes who participated in major junior or adult/elite cycling events using prospective and retrospective analysis of competition results. The official results of major junior (age < or = 18 years) and elite (age > 18 years) cycling races from 1980 to 2004 were analysed. Age-related aspects, career lengths, and success were compared between riders who presented results in both junior and elite races (JUNIOR ELITE) and riders who had no junior race results (ELITE ONLY). Altogether, 27,454 results of 8004 athletes from 108 countries were collected. We found that 29.4% of the elite athletes had participated in junior World Championships, and that 34% of the participants in junior World Championships later participated in major elite competitions. JUNIOR ELITE athletes are significantly more successful in several cycling disciplines and have their first and last elite result at a younger age than ELITE ONLY athletes. No difference was found in career lengths. The data presented here emphasize the importance of long-term training programmes in the development of peak performance in cycling.  相似文献

This nationwide survey studies the impact of convergence on reporters and producers in small and medium local television markets. The article examines the manner in which convergence-related responsibilities affect the daily routines of these news workers. It also assesses their perceptions of convergence and challenges they face, including concerns about the impact of convergence on the quality of their work. Authors compare these views to the opinions of news directors across the United States (gathered in previous research), finding significant differences between news workers' perspectives and those of their bosses.  相似文献
