Keeping up with the digital age: How the American Red Cross uses social media to build relationships
Forty individuals from the American Red Cross were interviewed to explore the use of social media in communicating with key publics. Results show that practicing public relations through social media is effective and necessary in the emerging digital age, as shown through the Red Cross’ development of a two-way dialogue with younger constituents, the media, and the community. This two-way dialogue has been accomplished primarily through Twitter and Facebook, with barriers such as lack of staff and time, and opportunities to improve National Headquarters and local chapter relations. The insights shared by the American Red Cross are useful for both public relations scholars and professionals to help them understand and apply social media practices to build strong, lasting relationships. 相似文献

近几年来,主权财富基金迅速兴起,并以其雄厚的资金实力,庞大的数量规模及日益增强的国际影响力,成为世界关注的焦点。本文在介绍主权财富基金内涵、分类、特征及兴起原因的基础上,着重分析了主权财富基金对21世纪国际经济关系在经济格局的重组、贸易摩擦的加剧和发展中国家与发达国家未来发展方向的转变方面的影响。并据此提出中国应加强央行对主权财富基金的管理,制定长期、灵活且多元化的投资发展战略,适度提高透明度,严格准入条件和健全风险防范体系的应对策略。 相似文献

Recent changes in American media have resulted in direct impacts on the work of PR professionals, from newsroom reductions in traditional media outlets to the rise of social media. This study examines changes in the media relations dynamic with qualitative, in-depth interviews from 12 PR professionals in a medium, eastern U.S. city. Findings include PR professionals doing less traditional media relations, mostly attributable to downsized newsrooms, and frustration with the resulting dearth of institutional knowledge, influx of young, inexperienced reporters, and shallow stories. While participants see opportunities to inject unfiltered messages in media, overall they value reporter relationships and using social media in communication with them and in their job. Although new media are seen as one more task on an already very full PR plate, participants acknowledge their importance and growing relevance. Overall, PR professionals see their and the industry's future including both traditional and new media. 相似文献

ABSTRACT The purpose of this qualitative study was to explore the social networks of Appalachian adolescents to understand socialization strategies and goals. A total of 46 interviews were conducted with five families (mothers, fathers, and adolescents) and 11 socialization agents the families identified as exerting significant influence in the lives of the adolescents. Interviews were transcribed and then analyzed using principles of grounded theory. Five themes developed from the interviews: the importance of community to the socialization process, adult involvement and support, adolescent monitoring, teaching respect and responsibility, and adolescent autonomy. Results suggest the need for in-depth investigation of adolescent development within a variety of cultural and social contexts to more fully understand these processes. 相似文献

AbstractThis article examines the communiqués issued by Subcomandante Marcos during the early years of the Zapatista rebellion in Mexico (1992–1998). It addresses a double voice, and a double mission, of these internet pronouncements: first, as a tool for a local Indigenous uprising in the state of Chiapas; second, as a part of a much broader anti-neoliberal and anti-neo-imperialist struggle. The article argues that the unusual interlacing of a local, almost intimate struggle with a much broader ideological struggle has its sources, models and origins, paradoxically, in U.S. Cold War anti-communist discourse of the 1950s. Both discourses featured almost priestly, technocratic, master-explainers of an unseen enemy; both resorted to normative narratives of domesticity and infantilization; both relied on masked anti-heroes. 相似文献

现代化的发展是社会技术、经济、政治、思想、文化等诸多方面要素综合作用的结果.然而,社会资源的市场配置是社会要素充分资源化而发挥其功能的重要条件,实现这一配置资源的市场配置关涉到社会结构转型问题,即发育个体与社会,建构社会公共领域,使之与国家间形成相对独立关系.实际上,市场经济与构建公共领域具有共生互动的性质.它既以个体、社会与政治公共领域的确立为条件,同时又是发育个体与社会,构建现代政治公共领域的平台. 相似文献

从中美苏战略三角到中美俄战略三角 总被引:1,自引:0,他引:1
自20世纪60年代以来,在中美苏(俄)三个大国之间先后形成了两个独特而复杂的战略三角关系。两大战略三角对世界范围的国际关系发挥了极其重大的作用。但由于它们形成于不同的时代,具有不同的性质、内涵、结构和走向,三大国在其中的地位、处境、作用和影响也不尽相同,因此中美俄战略三角并不是中美苏战略三角的简单恢复或延续。 相似文献
