The study reported here explored the social dimension of health-related blogs by examining blogging as a means to marshal social support and, as a result, achieve some of the health benefits associated with supportive communication. A total of 121 individuals who author a blog dedicated to their experience living with a specific health condition completed the study questionnaire. The number of blog posts made by respondents and proportion of posts with reader comments were positively associated with perceived social support from blog readers. The relationship between blog reader support and two outcomes related to well-being depended upon the support available in bloggers' strong-tie relationships with family and friends. Consistent with the social compensation (i.e., “poor get richer”) perspective, blog reader support was negatively associated with loneliness and positively associated with personal growth when support in strong-tie relationships was relatively lacking.  相似文献

In 2009, the Obama administration issued the Open Government Initiative that directed Executive agencies to improve transparency, openness in government, and public participation with government. The Obama administration views transparency and openness in government as a cost-effective and efficient process capable of improving public participation with government and public access to government information. To address the initiative in part, many agencies adopt social media as the means to disseminate information out to the public and to increase public participation with agency website content and activities. This exploratory study examines Executive agency use of social media and public participation with the media. Findings indicate that most agencies reviewed do use social media. The public does interact with the media and some agencies experience high overall participation levels; however, there are some issues with agency use of social media and public participation with the media.  相似文献

American television programs have been criticized for being filled with images endorsing capitalist consumerism and for being weighted toward the upper middle classes. This study proposed that heavy viewing of these distorted representations may culminate in decreases in viewers' life satisfaction. A path model investigated this supposition, based on material value and social comparison perspectives. Surveys were administered to 225 adults in a northeastern town in the United States, and the data were subjected to path analysis. The findings of this study suggest that heavy television viewing may be associated with material value, estimates of other people's affluence, and perceived gaps between the self and others in material affluence. Of importance, the findings also suggest that the perceived gaps between the self and others may be associated both with dissatisfaction with personal life and dissatisfaction with current social equality, whereas material value may be associated only with dissatisfaction with personal life.  相似文献

Background: Within NHS North West England there are 24 primary care trusts (PCTs), all with access to different types of library services. This study aims to evaluate the impact the type of library service has on online resource usage. Methodology: We conducted a large‐scale retrospective quantitative study across all PCT staff in NHS NW England using Athens sessions log data. We studied the Athens log usage of 30 381 staff, with 8273 active Athens accounts and 100 599 sessions from 1 January 2007 to 31 December 2007. Results: In 2007, PCTs with outreach librarians achieved 43% penetration of staff with active Athens accounts compared with PCTs with their own library service (28.23%); PCTs with service level agreements (SLAs) with acute hospital library services (22.5%) and with no library service (19.68%). This pattern was also observed when we looked at the average number of Athens user sessions per person, and usage of Dialog Datastar databases and Proquest full text journal collections. Discussion: Our findings have shown a correlation of e‐resource usage and type of library service. Outreach librarians have proved to be an efficient model for promoting and driving up resources usage. PCTs with no library service have shown the lowest level of resource usage.  相似文献
