[1] The Social Media Ecology: User Perceptions, Strategies and Challenges Front Stage on Social Media / Zhao, Xuan / Lampe, Cliff / Ellison, Nicole B. Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.89-100
ACM Digital Library Link
Summary: Many existing studies of social media focus on only one platform, but the reality of users' lived experiences is that most users incorporate multiple platforms into their communication practices in order to access the people and networks they desire to influence. In order to better understand how people make sharing decisions across multiple sites, we asked our participants (N=29) to categorize all modes of communication they used, with the goal of surfacing their mental models about managing sharing across platforms. Our interview data suggest that people simultaneously consider "audience" and "content" when sharing and these needs sometimes compete with one another; that they have the strong desire to both maintain boundaries between platforms as well as allowing content and audience to permeate across these boundaries; and that they strive to stabilize their own communication ecosystem yet need to respond to changes necessitated by the emergence of new tools, practices, and contacts. We unpack the implications of these tensions and suggest future design possibilities.

[2] Identity Work on Social Media Sites: Disadvantaged Students' College Transition Processes Education in the Classroom and Beyond / Morioka, Tsubasa / Ellison, Nicole B. / Brown, Michael Proceedings of ACM CSCW 2016 Conference on Computer-Supported Cooperative Work and Social Computing 2016-02-27 v.1 p.848-859
ACM Digital Library Link
Summary: Prior research suggests that some social media practices can play a role in shaping students' adjustment to college; however, the specific mechanisms by which social media can support the identity work associated with successful transitions to college are not well understood. This paper investigates how social media experiences and interactions can support college-focused identity construction for low-income, first-generation college students. Drawing on in-depth, semi-structured interviews with 31 emergent adults from disadvantaged backgrounds in the United States, we identify social media affordances that support the process of identity work during a critical transition period. Findings indicate that social media platforms support provisional identity work, but disadvantaged college students lack access to mentor-like figures that could be accessible through social media. We also find barriers to sharing information online that may extend to other life transitions in multiple life contexts and review the design implications of our findings.

[3] First-Generation Students and College: The Role of Facebook Networks as Information Sources Education in the Classroom and Beyond / Jeon, Grace YoungJoo / Ellison, Nicole B. / Hogan, Bernie / Greenhow, Christine Proceedings of ACM CSCW 2016 Conference on Computer-Supported Cooperative Work and Social Computing 2016-02-27 v.1 p.887-899
ACM Digital Library Link
Summary: Social network site (SNS) platforms have the potential to be effective information-seeking channels due to their technical and social affordances, such as the ability to broadcast content to a large group and to aggregate one's contacts. This study tests the impact of a Facebook app that allows users to visualize their network of Facebook Friends to see how it influences who adolescents identify as good sources of information about college. Comparing Friends selected by 24 high school seniors before and after viewing Facebook network visualizations reveals that first-generation students were more likely to select higher quality information sources among their Facebook Friends after exposure to the visualization. Our results suggest that social media can help users identify good human information sources by making hidden resources in one's network more visible.

[4] Playful Backstalking and Serious Impression Management: How Young Adults Reflect on their Past Identities on Facebook Unpacking Social Networks / Schoenebeck, Sarita / Ellison, Nicole B. / Blackwell, Lindsay / Bayer, Joseph B. / Falk, Emily B. Proceedings of ACM CSCW 2016 Conference on Computer-Supported Cooperative Work and Social Computing 2016-02-27 v.1 p.1475-1487
ACM Digital Library Link
Summary: Parents, educators, and policymakers have expressed concern about the future implications of young people's sharing practices on social media sites. However, little is known about how young people themselves feel about their online behaviors being preserved and resurfaced later in adulthood. We conducted semi-structured interviews with 28 college-going, primarily female, young adults about their use of social media and their transition from adolescence into young adulthood. We find that participants recognize archival value in their own Facebook histories, despite sometimes perceiving these histories to be embarrassing. They experience tensions between meeting their current self-presentational goals and maintaining the authenticity of historical content. To reconcile these tensions, they engage in retrospective impression management practices, such as curating past content. They also engage in "backstalking" behaviors, in which they view and engage with other users' Facebook histories -- openly with close ties and discreetly with weak ties. We consider this ludic engagement through the lens of emerging adulthood and discuss the theoretical implications of our findings, especially in light of emerging applications which intentionally resurface digital traces.

[5] Online Dating as Pandora's Box: Methodological Issues for the CSCW Community Panels / Zytko, Doug / Lingel, Jessa / Birnholtz, Jeremy / Ellison, Nicole B. / Hancock, Jeff Companion Proceedings of ACM CSCW 2015 Conference on Computer-Supported Cooperative Work and Social Computing 2015-03-14 v.2 p.131-134
ACM Digital Library Link
Summary: As a socio-technical phenomenon, online dating has significant appeal to researchers interested in various aspects of human-computer interaction -- presentation of self in online environments; norms of disclosure and deception; and the extent to which technological design informs dynamics of human relationships. With these many facets of socio-technical practice come important and complex methodological questions, where both the sensitivity of the topic and the specific technologies being studied can introduce practical and ethical obstacles. This panel brings together scholars across human computer interaction, communication, information studies, and Internet studies to examine methodological issues that have arisen in their own work on online dating, with the objective of broadening these issues of ethics and methods to the wider CSCW community.

[7] Help is on the way: patterns of responses to resource requests on Facebook Friendsourcing / Lampe, Cliff / Gray, Rebecca / Fiore, Andrew T. / Ellison, Nicole Proceedings of ACM CSCW 2014 Conference on Computer-Supported Cooperative Work and Social Computing 2014-02-15 v.1 p.3-15
ACM Digital Library Link
Summary: Research suggests that social network sites can support social capital exchanges, which are often triggered by requests for assistance, such as seeking recommendations or asking for favors. Responsiveness to these requests for help is important to study because these interactions have the potential to affect users' overall satisfaction with the experience of using SNSs, signal social grooming functions that are an essential part of relationship maintenance, and affect social capital processes. In this paper, we study a corpus of public status updates posted to Facebook (N=7,466) in order to identify the pattern of responses to status updates that attempt to mobilize resources from the poster's Facebook network. Findings suggest that mobilization requests are treated differently than other kinds of posts; posts that attempt to mobilize help receive more comments than non-mobilization attempts. Additionally, responses occur more quickly and are shaped by the type of support requested (e.g., a recommendation vs. a favor). These findings help us better understand the role of help-seeking behaviors in the social capital conversion process as it unfolds via social media.

[8] Favors from Facebook friends: unpacking dimensions of social capital Papers: managing social media / Jung, Yumi / Gray, Rebecca / Lampe, Cliff / Ellison, Nicole Proceedings of ACM CHI 2013 Conference on Human Factors in Computing Systems 2013-04-27 v.1 p.11-20
ACM Digital Library Link
Summary: Past research has demonstrated a link between perceptions of social capital and use of the popular social network site, Facebook. Williams' Internet Social Capital Scales, based on Putnam's formulation, tap into sub-dimensions of social capital that have not been broadly used yet may enlighten our understanding of the different ways in which connecting with others online can facilitate access to resources embedded within our social relationships. In this study, we segment Williams' Internet Social Capital Scales into various sub-dimensions using factor analysis and explicate the distinct facets of social capital through a lab experiment in which Facebook users (N=98) request a small favor from their Facebook network. We find that some sub-dimensions play a significant role in getting favors from Facebook friends while bonding and bridging social capital do not significantly predict responses to favor requests.

[9] Users and nonusers: interactions between levels of adoption and social capital Understanding people's practices in social networks / Lampe, Cliff / Vitak, Jessica / Ellison, Nicole Proceedings of ACM CSCW'13 Conference on Computer-Supported Cooperative Work 2013-02-23 v.1 p.809-820
ACM Digital Library Link
Summary: Although Facebook is the largest social network site in the U.S. and attracts an increasingly diverse userbase, some individuals have chosen not to join the site. Using survey data collected from a sample of non-academic staff at a large Midwestern university (N=614), we explore the demographic and cognitive factors that predict whether a person chooses to join Facebook. We find that older adults and those with higher perceived levels of bonding social capital are less likely to use the site. Analyzing open-ended responses from non-users, we find that they express concerns about privacy, context collapse, limited time, and channel effects in deciding to not adopt Facebook. Finally, we compare non-adopters against users who differ on three dimensions of use. We find that light users often have social capital outcomes similar to, or worse than, non-users, and that heavy users report higher perceived bridging and bonding social capital than either group.

Summary: Research has identified a link between Facebook use and bridging social capital, which speaks to the informational resources provided by a diverse network of connections. In order to explicate the mechanism through which Facebook may help individuals mobilize these embedded informational and support resources, this study explores the role of bridging social capital, question type, and relational closeness on the perceived utility and satisfaction of information obtained through questions posed to one's network of Facebook Friends through the status update feature. Employing a mixed-method approach, we utilize survey data collected from a sample of non-academic university staff (N=666), as well as actual Facebook question examples and responses collected during a follow-up lab session from a subset of this sample (N=71). Results indicate that question-askers' bridging social capital positively predicts the utility of responses received on SNS, while useful responses are more likely to be received from weaker ties.

Summary: Social media question asking, in which people use Internet technologies to solicit help from other people, is an increasingly common way for people to find information. This workshop brings together researchers studying social media question asking from a variety of perspectives, including social scientists seeking to understand and describe the phenomenon and those seeking to create improved experiences through innovation in system building or user interface design.

[12] Perceptions of Facebook's value as an information source With a little help from my friends / Lampe, Cliff / Vitak, Jessica / Gray, Rebecca / Ellison, Nicole Proceedings of ACM CHI 2012 Conference on Human Factors in Computing Systems 2012-05-05 v.1 p.3195-3204
ACM Digital Library Link
Summary: Facebook has become an increasingly important tool for people engaging in a range of communication behaviors, including requesting help from their social network to address information needs. Through a study of 614 staff members at a large university, we show how social capital, network characteristics, and use of Facebook are related to how useful individuals find Facebook to be for informational purposes and their propensity to seek different types of information on the site. We find that bridging social capital and engagement with one's network through directed communication behaviors are important predictors of these dimensions of information seeking; furthermore, a number of demographic and usage behavior differences exist between those who choose to engage in information-seeking behaviors on Facebook and those who do not. Finally, when predicting information-seeking behaviors, we identify a significant interaction between users' perceptions of Facebook as appropriate for purposes beyond the purely social and their engagement with their network.

[13] "Why won't you be my Facebook friend?": strategies for managing context collapse in the workplace Posters / Vitak, Jessica / Lampe, Cliff / Gray, Rebecca / Ellison, Nicole B. Proceedings of the 2012 iConference 2012-02-07 p.555-557
ACM Digital Library Link
Summary: 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.

Summary: Research on social network sites (SNSs) typically employ measures that treat SNS use as homogenous although the user-base, user practices, and feature sets of these tools are increasingly diverse. Using a uses and gratifications approach, we address this problem by reconceptualizing SNSs as collections of features. Survey data collected from undergraduate students at a large Midwestern university (n = 267) revealed that users' motivations for using Facebook predict their use of different features, such as status updates and Wall posts, but features that share similar capabilities do not necessarily share underlying motivations for use. When these results are contrasted against models employing a more unidimensional measure of Facebook use, we find differences between motivations for both general Facebook use and use of specific features of the site. This suggests that unidimensional measures of SNS use obfuscate motivations for using specific features. Theoretical and methodological implications of these findings and this approach are discussed.

ACM Digital Library Link
Summary: 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.

[17] Student athletes on facebook Me, us and them: affiliation, reputation and social media use / Lampe, Cliff / Ellison, Nicole B. Proceedings of ACM CSCW'10 Conference on Computer-Supported Cooperative Work 2010-02-06 p.193-196
Keywords: facebook, social network sites, student athletes
ACM Digital Library Link
Summary: 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.

[18] Bowling online: social networking and social capital within the organization Social networking / Steinfield, Charles / DiMicco, Joan M. / Ellison, Nicole B. / Lampe, Cliff Proceedings of the 2009 International Conference on Communities and Technologies 2009-06-25 p.245-254
ACM Digital Library Link
Summary: Within an organizational setting, social capital facilitates knowledge management processes in that it enables individuals to locate useful information, draw on resources and make contributions to the network. This paper explores the relationship between various dimensions of organizational social capital and the use of an internal social network site (SNS). We hypothesize that the use of a SNS contributes to social capital within the organization in that SNS users are able to maintain larger networks of heterogeneous contacts. Additionally, the affordances of the site support social interaction between users, thus helping individuals maintain existing relationships and deepen developing ones. We find that bonding relationships, sense of corporate citizenship, interest in connecting globally, and access to new people and expertise are all associated with greater intensity of use of the social network site.

Summary: 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.

[21] A familiar face(book): profile elements as signals in an online social network Online representation of self / Lampe, Cliff A. C. / Ellison, Nicole / Steinfield, Charles Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007-04-28 v.1 p.435-444
ACM Digital Library Link
Summary: Using data from a popular online social network site, this paper explores the relationship between profile structure (namely, which fields are completed) and number of friends, giving designers insight into the importance of the profile and how it works to encourage connections and articulated relationships between users. We describe a theoretical framework that draws on aspects of signaling theory, common ground theory, and transaction costs theory to generate an understanding of why certain profile fields may be more predictive of friendship articulation on the site. Using a dataset consisting of 30,773 Facebook profiles, we determine which profile elements are most likely to predict friendship links and discuss the theoretical and design implications of our findings.

[22] The truth about lying in online dating profiles Online representation of self / Hancock, Jeffrey T. / Toma, Catalina / Ellison, Nicole Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007-04-28 v.1 p.449-452
ACM Digital Library Link
Summary: Online dating is a popular new tool for initiating romantic relationships, although recent research and media reports suggest that it may also be fertile ground for deception. Unlike previous studies that rely solely on self-report data, the present study establishes ground truth for 80 online daters' height, weight and age, and compares ground truth data to the information provided in online dating profiles. The results suggest that deception is indeed frequently observed, but that the magnitude of the deceptions is usually small. As expected, deceptions differ by gender. Results are discussed in light of the Hyperpersonal model and the self-presentational tensions experienced by online dating participants.

Summary: 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.
