In recent years, geographers and urban sociologists have sought to map and understand the emergence and development of lesbian and gay spaces within the city — popularly dubbed ‘the scene’. It is often asserted that the city is a space of sexual liberation and that specifically the ‘scene’ can play an important part in lesbian and gay men's identity formation and development. However, despite the range and richness of the academic literature on the production and emergence of lesbian and gay urban spaces, relatively little attention has been paid to the actual role of the scene in the ‘coming out’ process and the way young lesbians and gay men negotiate transitions to adulthood. This article addresses this neglect by drawing on empirical work with lesbians and gay men in the UK to explore what the scene has meant to them. In the first half of the article we focus on the positive roles that the scene can play in helping young people to find themselves as they make the transition from childhood to adulthood. In the second half of the article we consider the risks that they can encounter in the process. We conclude by reflecting on the scene as a paradoxical space, and on the implications of this research for the youth transitions and urban studies literatures, and for social policy.  相似文献

Most studies on Scandinavian industrial relations have inevitably focused on Sweden, and little has so far been written on Danish industrial relations[1]. This article highlights the similarities and differences between the Danish system and the ‘Swedish model’, and examines some of the current issues in Danish industrial relations.  相似文献

Organizations are using Group Support Systems (GSSs) to improve the quality of group meetings. Keypad‐based GSSs are a widely used form of this technology, yet there has been little research on their use and effects. This paper reports the findings of a survey of facilitators of a particular keypad GSS. Facilitators indicate that keypad technology improves the quality of meetings for a variety of tasks in a range of group settings and cultures. The findings are in general agreement with field studies of workstation‐based systems.  相似文献

We introduce international mobility of knowledge workers into a model of Nash equilibrium IPR policy choice among countries. We show that governments have incentives to use IPRs in a bidding war for global talent, resulting in Nash equilibrium IPRs that can be too high, rather than too low, from a global welfare perspective. These incentives become stronger as developing countries grow in size and wealth, thus allowing them to prevent the ‘poaching’ of their ‘brains’ by larger, wealthier markets.  相似文献

Drawing on configuration theory, we develop and test a model which posits that overall firm performance will be influenced by how well the marketing organization??s cultural orientation (i.e., market, adhocracy, hierarchy, or clan) complements alternative business strategies (i.e., Prospector, Analyzer, Low-Cost Defender, Differentiated Defender) after controlling for other, key firm-level variables. Responses from a sample of senior marketing managers provide partial support for the model and demonstrate that high-performing businesses of one strategy type have a different cultural orientation than high-performing businesses of the other strategy types. And, contrary to previous research, the results of this study show that each of the cultural orientations may play a role in creating superior performance. We conclude with a discussion of the implications for scholars and for managers.  相似文献

在去参加第53届威尼斯艺术双年展开幕式之前的几天,我受邀出席了在意大利北部城市Bergamo的当代美术馆GAMeC举行的国际年轻策展人论坛,今年论坛的主题是"国际策展人的终结?"围绕着像威尼斯双年展、卡塞尔文献展等全球达几十个之多的国际性展览的策展策略和模式进行反思和讨论。讨论之中也不免提到了威尼斯双年展这个一直以一个策展人为主导选择艺术家的大  相似文献

The widespread use of barcodes has significantly contributed to accurate, efficient and economic inventory management in warehouses and distribution centres. However, its efficiency has always been limited by the primary method of reading barcodes with a handheld laser scanner. Compared with this reading by line-of-sight at close proximity, vision-based barcode reading algorithms can further improve efficiency, particularly if accompanied by automated data collection platforms such as drones. This paper introduces algorithms that are able to automatically extract barcodes from video data, and verifies their feasibility and promise for inventory management in warehousing applications. Three key techniques corresponding to different recognition levels are proposed: For a known barcode region, a Harris corner detector and Hough transform-based algorithm is applied to quickly estimate the angle by which the frame area needs to rotate to orient the bars vertically for information extraction. Then, the idea of exploiting connectivity and geometry property of barcode areas is proposed to directly recognise multiple barcode regions in a single video frame to eliminate reading difficulties resulting from interactive influence of multiple juxtaposed barcodes, and to save computation time by only processing frame areas of interest for valid barcodes. In addition, a histogram difference-based fast extraction strategy is designed to further improve efficiency by reducing duplicate information processing. Finally, the performance of each technique is evaluated by analysing video data from a large logistics warehouse, demonstrating satisfactory performance in inventory management applications.  相似文献
