Understanding the majority opinion formation process in online environments: An exploratory approach to Facebook     

Sangwon Lee  Taehyun Ha  Daeho Lee  Jang Hyun Kim 《Information processing & management》2018,54(6):1115-1128

Majority opinions are often observed in the process of social interaction in online communities, but few studies have addressed this issue with empirical data. To identify an appropriate theoretical lens for explaining majority opinions in online environments, this study investigates the skewness statistic, which indicates how many “Likes” are skewed to major comments on a Facebook post; 3489 posts are gathered from the New York Times Facebook page for 100 days. Results show that time is not an influential factor for skewness increase, but the number of comments has a logarithmic relation to skewness increase. Regression models and Chow tests show that this relationship differs depending on topic contents, but majority opinions are significant in overall. These results suggest that the bandwagon effect due to social affordance can be a suitable mechanism for explaining majority opinion formation in an online environment and that majority opinions in online communities can be misperceived due to overestimation.  相似文献

Suffering in sport: why people willingly embrace negative emotional experiences     

Michael S. Brady 《体育哲学杂志》2019,46(2):115-128

ABSTRACT

Nearly everyone agrees that physical pain is bad. Indeed, if anything merits the status of a platitude in our everyday thinking about value, the idea that pain is bad surely does. Equally, it seems clearly true that emotional suffering – despair, loneliness, grief, disappointment, guilt, shame, lovesickness, and the like – are all bad as well. We are strongly inclined to pity and feel sorry for those who suffer emotionally in these ways; we are motivated, at least some of the time, to do what we can to alleviate their suffering. Given this, it might seem curious that pain and suffering are so integral to sport – whether one is a participant or a spectator. There’s nothing particularly puzzling about pain and suffering that is inadvertently related to sport – as when an athlete injures her hamstring and has to miss her chance at Olympic glory, or when supporters face the misery of getting up at 6am because an away game has been scheduled to start at noon. But there does seem to be something curious about the extent to which pain and suffering are voluntarily embraced by participants and spectators, as the quotation from Nick Hornby aptly illustrates. Why do people willingly engage in something that brings about so much suffering? In this paper, I’ll attempt to answer this question.¹  相似文献

Occupational Social Work Education for Employee Assistance Practice     

Daniel Hughes  Carly Newhouse 《Journal of Teaching in Social Work》2018,38(4):379-397

ABSTRACT

This article explores the current state of Occupational Social Work/Employee Assistance (OSW/EA) education. It examines the relationship between social work curricula, field placement experiences, and entry-level employment opportunities in the OSW/EA field. It is based on an educational initiative called the Partnership for Employee Assistance Education. Drawing on the OSW/EA literature, surveys, and focus group materials, the article concludes that the nature of OSW/EA is being reshaped by information technology, shifting demographics, globalization, and evolving terms and conditions of employment. The authors discuss how the graduate-level OSW/EA curriculum and field placements are being transformed to reflect these trends. Concepts such as Organizational Social Work and organizational intelligence are discussed. Innovative educational strategies are recommended. Finally, the authors argue that the contemporary workplace offers potential opportunity for innovative social work practice and education.  相似文献

高天宇  李佳薇 《广州体育学院学报》2019,(5):7-13

青少年体育健康问题上升国家战略高度。“青少年体育健康公共服务”是一个在青少年体育领域内，由“体育健康”和“体育公共服务”综合而成的全新概念，学界还未深入探讨与挖掘。充分结合“健康管理”理论，基于对“青少年体育健康”和“体育公共服务”相关研究文献的回顾，归纳“青少年体育健康公共服务”内涵与特征。概念特征包括：“学校体育”“青少年体育俱乐部”是核心供给主体；健康医疗等事业、非营利性机构是重要支撑；始终强调青少年受众被动接受“体育健康促进”与主动应用“体育健康素养”相结合；供给产品具有“纯公共物品”性质，公共财政补贴是解决公共服务资源配置矛盾关键方式；“互联网虚拟社区”是实现多元主体协同供给的技术基础与激励条件。最后，基于概念属性展望“青少年体育健康公共服务”的未来研究趋势，包括：开发“运动干预”“心理调试”和“营养膳食”三维评估指标体系；完善“学校”“社区”“医疗部门”“健康管理机构”和“家庭”的协同供给机制；深度开发“青少年体育俱乐部”和“青少年联赛体系”营造“体育健康素养培育”空间；实现“青少年体育健康公共服务”均等化局限，以及加快“青少年体育健康公共服务”互联网平台建设，破解公共服务资源闲置问题。  相似文献   

Great Expectations? Childhood,Family, and Middle-Class Social Mobility in Nineteenth-Century England     

Christina De Bellaigue 《Cultural and Social History》2019,16(1):29-46

ABSTRACT

Existing histories of social mobility have focused on adults and on measuring the achievement of individual upward mobility. However, children and families were central to mobility strategies. Using the papers of the Heywoods of Bolton, this article examines how the families of the industrial middle class endowed their offspring with the goods and character needed to secure their social standing, highlighting the emotional intricacy of these processes. It demonstrates that such families conceived of social mobility as a familial project and that rather than pursuing upward mobility, their chief objective was to guard against social decline.  相似文献
