This article explores the mutually beneficial relationship between the American swimsuit and film industries during the first three decades of the twentieth century. Three examples will be used: Fatty and the Bathing Beauties from 1913 (prior to regulated film content), Footlight Parade from 1933 (when limited self-regulation had been put in place, but was not yet rigorously enforced) and the Tarzan film franchise (which spans both the second period and a later, third period of actual implementation and subsequent negotiation). Using these examples, the paper will consider several of the popular associations attached to the swimmer and the swimsuit. It will discuss the ways in which Hollywood utilised the swimsuit, the swimmer and swimming in both its films and its promotional materials and will demonstrate how through the sporting associations of both the garment and sports stars, film producers negotiated the processes of censorship and self-regulation while allowing the continued use of semi-naked and eroticised bodies, to their own profit and to that of the increasingly fashionable swimwear industry. 相似文献

Recent controversies surrounding privacy have sparked a move by regulators toward the idea of privacy by design (PbD), a concept pioneered by Ontario Information and Privacy Commissioner Ann Cavoukian. Industry has also started to recognize the importance of taking privacy seriously, with various PbD corporate initiatives currently underway. However, some commentators have criticized PbD for being too vague. Using three case studies and a range of best practice examples of PbD, privacy impact assessments (PIAs), and privacy-enhancing technologies (PETs), this article addresses the gap between the abstract principles of PbD and their operationalization into more concrete implementation guidelines for software engineers. 相似文献

Creating value in ecosystems: Crossing the chasm between knowledge and business ecosystems 总被引:1,自引:0,他引:1
Policy makers take initiatives to stimulate knowledge ecosystems in technology hotspots. It is implicitly assumed that these ecosystems will lead to value networks through which the participating companies can realize a competitive advantage. Value networks refer to business ecosystems where the value proposition is offered by a group of companies which are mutually complementary. The strategy literature suggests that business ecosystems lead to competitive advantages for each of the partners in the ecosystem. Based on a unique hand-collected database of 138 innovative start-ups in the region of Flanders, we analyze the knowledge and business ecosystem and the financial support network. We find that the knowledge ecosystem is well structured and concentrated around a number of central actors while the business ecosystem is almost non-existent at the local level. Further, we find that the financial support network is almost 100% publicly backed and fails to bridge the knowledge and business ecosystem. The implications for policy makers who tend to focus on the development of local ecosystems are discussed. 相似文献

OBJECTIVE: This study compares homeless women who had childhood histories of foster care or other out-of-home placement to those who have not. METHOD: A countywide probability sample of homeless women (n = 179) received structured interviews. RESULTS: One-third of homeless women reported being raised apart from their parents. Among women with children under age 18, most (61.5%) had children who had lived in foster care or other out-of-home placements. Variables associated with homeless mothers' children living in foster care or other out-of-home placements were: Child was school-age, mother was age 35 or older, mother had a current alcohol or drug use disorder, mother experienced childhood sexual abuse, and mother ran away from home (when under age 18). CONCLUSIONS: Parenting is difficult for homeless mothers who may need to place their children with others to facilitate school attendance. Parent-child interaction may be problematic in family shelters where privacy is rare. Thus, programs promoting family preservation for homeless mothers should provide parenting support as well as permanent housing. 相似文献
