Zube, Paul, Velasquez, Alcides, Ozkaya, Elif, Lampe, Cliff and Obar, Jonathan (2012): Classroom Wikipedia participation effects on future intentions to contribute. In: Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 403-406.
One of the biggest challenges faced by social media sites like Wikipedia is how to motivate users to contribute content. Research continues to demonstrate that only a small percentage of users contribute to user-generated content sites. In this study we assess the results of a Wikimedia Foundation initiative, which had graduate and undergraduate students from 22 U.S. universities contribute content to Wikipedia articles as part of their coursework. 185 students were asked about their participation in the initiative and their intention to participate on Wikipedia in the future. Results suggest that intentions to continue contributing are influenced by the initial attitude towards the class, and the degree to which students perceived they were writing for a global audience.

Wash, Rick and Lampe, Cliff (2012): The power of the ask in social media. In: Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 1187-1190.
Social computing and social media systems depend on contributions from users. We posit the existence of a latent demand for contribution: many users want to contribute but don't. We then test a simple interface that can induce these users to actually contribute: we display a popup window asking users to contribute. In a real-world randomized field experiment, we found that asking them to contribute right now is ineffective, but reminding the users to contribute actually leads to approximately a 23% increase in contributions with no reduction in quality. However, this effect wanes as users habituate to the popups.

Social media is one way that individuals share information, present themselves, and manage their social interactions in both personal and professional contexts. While social media benefits have been examined in the literature, relatively little attention has been paid to the relationship of privacy to these benefits. Privacy has traditionally been framed as a way for individuals to protect themselves from the consequences of too much information disclosure. However, privacy can be a means to enhance social media outcomes and is essential for coordinating cooperative relationships. In this workshop we seek to: a) broaden the lens of social media privacy research to examine the benefits and outcomes of interactional privacy as they relate to social media goals; and b) discuss the design of social media interfaces that are responsive to both relational and privacy needs.

Sarkar, Chandan, Wohn, Donghee Yvette and Lampe, Cliff (2012): Predicting length of membership in online community "everything2" using feedback. In: Companion Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 207-210.
In this paper, we examine how specific features of participation and feedback can predict the length of membership within a user generated content based online community called 'Everything2'. Examining almost 10 years of server data we found that not all feedback is the same: feedback on the user's initial contribution was the strongest factor explaining membership length. Receiving one negative initial feedback did not significantly affect membership, but sequential negative initial feedback decreased the likelihood of staying longer on the site.

Lampe, Cliff and Roth, Rebecca (2012): Implementing social media in public sector organizations. In: Proceedings of the 2012 iConference 2012. pp. 191-198.
Social media has been widely adopted by organizations in the recent past, and public sector organizations are also showing an increased interest in using this tool to meet their goals. In this paper, we describe three cases of social media adoption by public sector organizations, and the struggles faced in that implementation. We argue through the experience of implementing these systems that the characteristics of non-profit organizations, including the government and community service organizations that interact in the public sector, exacerbate problems of groupware adoption. In particular, public sector organizations involve multiple stakeholders coordinating in a distributed fashion, which leads to barriers to social media adoption to accomplish their goals.

This poster presents a preliminary analysis of data collected from staff personnel at a large U. S. university regarding their use of the social network site (SNS) Facebook in their personal and professional lives. Sixty-five percent of online American adults now have a profile on a SNS, and Facebook is increasingly utilized in organizational settings such as universities as a tool for information dissemination, recruiting, and promotion of the organization and its programs. Analysis of interview data (N = 26) found that while social media outlets like Facebook offer a number of advantages for reaching diverse populations, navigating work/life boundaries on Facebook was a concern for many participants. Through the lens of context collapse -- the flattening of multiple distinct audiences into a singular group -- we explicate these concerns, focusing on participants' strategies for maintaining boundaries between their personal and professional lives.

McCully, Wyl, Lampe, Cliff, Sarkar, Chandan, Velasquez, Alcides and Sreevinasan, Akshaya (2011): Online and offline interactions in online communities. In: Proceedings of the 2011 International Symposium on Wikis and Open Collaboration 2011. pp. 39-48.
Online communities, while primarily enacted through technology-mediated environments, can also include offline meetings between members, promoting interactivity and community building. This study explores the offline interactions of online community members and its subsequent impact on online participation. We argue that offline interactions have a counterintuitive impact on online participation. Although these offline interactions strengthen relationships, these relationships undermine the community's sustainability in terms of site participation. Participation has been defined as contribution of content to the online community. A multi-method analysis technique using content analysis, qualitative interviews, and server level quantitative data of users in Everything2.com supports our claim.

Social network sites (SNSs) are bundles of information and communication tools that can be used to support collaboration, among other uses. In a qualitative study of adult Facebook users (N=18), we found that some users did turn to the site for information uses that are embedded in social activities, including organizing events, establishing online groups, and seeking information. We also discuss the features of Facebook that respondents discussed as being important to these uses.

A consistent theoretical and practical challenge in the design of socio-technical systems is that of motivating users to participate in and contribute to them. This study examines the case of Everything2.com users from the theoretical perspectives of Uses and Gratifications and Organizational Commitment to compare individual versus organizational motivations in user participation. We find evidence that users may continue to participate in a site for different reasons than those that led them to the site. Feelings of belonging to a site are important for both anonymous and registered users across different types of uses. Long-term users felt more dissatisfied with the site than anonymous users. Social and cognitive factors seem to be more important than issues of usability in predicting contribution to the site.

While there is a growing body of work that documents online behavior in its different forms, there has been little research that develops holistic models and theories of online behavior. This workshop will draw together internet researchers to develop new understandings of online behavior across a diversity of activities and applications. The emphasis is on new theories and models that can be used to understand and predict social behavior as underlying technologies change. This workshop will work as a valuable bridge across individual disciplines and empirical studies supporting the generalization of understandings and approaches.

Lampe, Cliff and Ellison, Nicole B. (2010): Student athletes on facebook. In: Proceedings of ACM CSCW10 Conference on Computer-Supported Cooperative Work 2010. pp. 193-196.
Student athletes at U.S. universities are bound by rules affecting their participation in their sport and are highly visible to their fellow students and a larger public of fans. This difference makes them more likely than other students to be sensitive to issues of impression management and use of social network sites (SNSs). In this paper, we show how student athletes at a large university engage with the social network site Facebook compared with their fellow students, including differences in the size of their networks, reported uses of the site, and perceptions about their audience. This work shows that while student athletes have a higher anticipation of being watched, they have similar uses and concerns compared to other students.

As social computing systems persist over time, the user experiences and interactions they support may change. One type of social computing system, Social Network Sites (SNSs), are becoming more popular across broad segments of Internet users. Facebook, in particular, has very broad participation amongst college attendees, and has been growing in other populations as well. This paper looks at how use of Facebook has changed over time, as indicated by three consecutive years of survey data and interviews with a subset of survey respondents. Reported uses of the site remain relatively constant over time, but the perceived audience for user profiles and attitudes about the site show differences over the study period.

Large numbers of college students have become avid Facebook users in a short period of time. In this paper, we explore whether these students are using Facebook to find new people in their offline communities or to learn more about people they initially meet offline. Our data suggest that users are largely employing Facebook to learn more about people they meet offline, and are less likely to use the site to initiate new connections.

Many virtual communities involve ongoing discussions, with large numbers of users and established, if implicit rules for participation. As new users enter communities like this, both they and existing members benefit when new users learn the standards for participation. Slashdot is a news and discussion site that has developed a system of distributed moderation to provide feedback about the value of posts on their site. This study examines three explanations for how new users learn to participate in a digital community: learning transfer from previous experiences, observation of other members, and feedback from other members. We find that new user behavior is affected by a combination of their viewing behavior, the moderation feedback they receive, and replies to their comments.

Lampe, Cliff and Resnick, Paul (2004): Slash(dot) and burn: distributed moderation in a large online conversation space. In: Dykstra-Erickson, Elizabeth and Tscheligi, Manfred (eds.) Proceedings of ACM CHI 2004 Conference on Human Factors in Computing Systems April 24-29, 2004, Vienna, Austria. pp. 543-550.
Can a system of distributed moderation quickly and consistently separate high and low quality comments in an online conversation? Analysis of the site Slashdot.org suggests that the answer is a qualified yes, but that important challenges remain for designers of such systems. Thousands of users act as moderators. Final scores for comments are reasonably dispersed and the community generally agrees that moderations are fair. On the other hand, much of a conversation can pass before the best and worst comments are identified. Of those moderations that were judged unfair, only about half were subsequently counterbalanced by a moderation in the other direction. And comments with low scores, not at top-level, or posted late in a conversation were more likely to be overlooked by moderators.
