基于情感倾向和观察学习的在线评论有用性影响因素研究

已有在线评论的研究都在消费者不能针对同一商品分开做正面评价和负面评价的实践背景下开展, 但类似于"中关村在线" 的评论系统已经允许消费者分别做正负两种评论, 并允许客户进行晒单, 本文主要研究这种区分在线评论的正负型评论及基于晒单的观察学习行为对有用性的影响. 结论表明: 区分背景下的在线评论极端性、 在线评论长度和晒单行为等都对在线评论的有用性产生显著影响, 负面在线评论的影响要大于正面在线评论.

Evaluation in the Social Studies

Online role-playing games such as World Of Warcraft represent new participatory cultures in which today's students engage every day. They are appealing to players largely because of the social aspects of game play. Some features of massively multiplayer online role-playing games (MMORPGs) can be incorporated into classroom culture to create more dynamic interactions between students and improve both content instruction and civic competence.     

Engaging stakeholders through social networking: How nonprofit organizations are using Facebook

Since social networking sites, such as MySpace and Facebook, began allowing organizations to create profiles and become active members, organizations have started incorporating these strategies into their public relations programming. For-profit organizations have used these sites to help launch products and strengthen their existing brands; however, little is known about how nonprofit organizations are taking advantage of the social networking popularity. Through a content analysis of 275 nonprofit organization profiles on Facebook, this study examines how these new social networking sites are being used by the organizations to advance their organization's mission and programs. Solely having a profile will not in itself increase awareness or trigger an influx of participation. Instead careful planning and research will greatly benefit nonprofits as they attempt to develop social networking relationships with their stakeholders.     

Women Auto Know: Automotive knowledge,auto activism,and women's online car advice

Although women influence nearly 85 percent of new car sales, their experience at automotive dealerships differs significantly from that of men. Not only are women subject to sexist and patronizing behavior from automotive personnel, but they also often wind up paying considerably more for a vehicle than a male customer. In the past two decades, the Internet has evolved as a significant source of automotive information and advice. While the majority of car advice websites offer guidance to the general public, a handful address the automotive concerns of the female driver. These sites are significant not only for the information they make accessible to female visitors, but for what women gain—as drivers, consumers, and political actors—by reading them. This paper examines four popular websites that cater specifically to the woman driver. Calling upon feminist epistemologies, it demonstrates how such online locations empower women to become more informed drivers and consumers through the accumulation and distribution of women's automotive knowledge. Not only does this automotive knowledge aid women as negotiators, but it also provides them with the tools necessary to radically transform the hostile auto dealership culture, ultimately benefiting all in the market for an automobile.     

Mapping the social geographies of autism – online and off-line narratives of neuro-shared and separate spaces

This paper draws together empirical work that has been produced by the authors in two different autistic spaces: the Swedish magazine Empowerment produced by and aimed at adults with autism, and English-speaking autistic communities online. While the two points of data collection are quite different, there are important points of commonality that enable us to explore central issues concerning autistic and neurotypical space and the meanings assigned to these in different contexts. The paper aims to introduce the notion of social geographies of autism, based on talks among adults with autism and a social movement to promote autistic identities, giving examples from our previous work that has spanned both online and off-line spaces. Key issues discussed in the paper include a focus on autistic political platforms and the carving out of both social and political spaces for people with autism. In doing so, neuro-separate and neuro-shared spaces must be negotiated.     

The Social Life of Homelessness: Myths and Social Standing

There are two groups of people, the Insiders and the Outsiders. Insiders have access to a network of social transactions that enable them to tap into resources and information that lead to employment, housing, and other opportunities for upward mobility. These processes are often informal, and sometimes exclusive. The social networks that Outsiders have pertain largely to the acquisition of a meal or a night’s shelter. They do not have access to the better-endowed social networks of Insiders, and are therefore not privy to the informational and resources exchange that takes place therein. This translates into fewer job interviews, fewer housing applications, etc. Finally, this means that when an Outsider experiences a stressor (i.e., the flu, eviction, unemployment), it can take on crisis proportions leading ultimately to homelessness. However dim the prospects of Outsiders are, there are specific corrective processes, which can be implemented.     

Student Perspectives of Online Discussions: Strengths and Weaknesses

SUMMARY

Limited research exists that examines student perceptions of online discussions in fully online classes. This is a report of initial investigation into undergraduate distance education majors' perspectives of the pedagogical value of online discussions. Over a two semester period (Spring and Fall, 2003), students taking the same online course delivered using Web Course Tools (WebCT) were surveyed regarding opinions of online discussions. The students surveyed were undergraduate students enrolled in a fully online degree program at New Mexico State University (NMSU). Although limitations exist due to small sample size and a non-standardized data collection instrument, findings from this exploratory study offer insight into undergraduate distance education student opinions of the strengths and weaknesses of online discussions as a pedagogical tool.     

The School Success Profile Online

SUMMARY

This article provides an overview of the purposes, development, and implementation of the School Success Profile Online (SSP)–a computerized, self-report survey for middle and high school students. The SSP takes advantage of World Wide Web technology and the increasing access of public schools to computers and the Internet to assess students' perceptions of their neighborhoods, schools, peers, and families, as well as their own psychological and physical health and school performance. The individual and group profiles generated by the SSP can help school social workers identify areas of concern, plan their interventions with students, and evaluate the impact of their efforts at the end of interventions.
