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.

This study assesses whether Facebook users have different ‘connection strategies,’ a term which describes a suite of Facebook-related relational communication activities, and explores the relationship between these connection strategies and social capital. Survey data (N = 450) from a random sample of undergraduate students reveal that only social information-seeking behaviors contribute to perceptions of social capital; connection strategies that focus on strangers or close friends do not. We also find that reporting more ‘actual’ friends on the site is predictive of social capital, but only to a point. We believe the explanation for these findings may be that the identity information in Facebook serves as a social lubricant, encouraging individuals to convert latent to weak ties and enabling them to broadcast requests for support or information.

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.

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.

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.

Vertical information systems (VIS) standards are technical specifications designed to promote coordination among the organizations within (or across) vertical industry sectors. Examples include the bar code, electronic data interchange (EDI) standards, and RosettaNet business process standards in the electronics industry. This contribution examines VIS standardization through the lens of collective action theory, applied in the literature to information technology product standardization, but not yet to VIS standardization, which is led by heterogeneous groups of user organizations rather than by IT vendors. Through an intensive case analysis of VIS standardization in the U.S. residential mortgage industry, VIS standardization success is shown to be as problematic as IT product standardization success, but for different reasons. VIS standardization involves two linked collective action dilemmas-standards development and standards diffusion- with different characteristics, such that a solution to the first may fail to resolve the second. Whereas prior theoretical and empirical research shows that IT product standardization efforts tend to splinter into rival factions that compete through standards wars in the marketplace, successful VIS standards consortia must encompass heterogeneous groups of user organizations and IT vendors without fragmenting. Some tactics successfully used to solve the collective action dilemma of VIS standardization (e.g., governance mechanisms and policies about intellectual property protection) are also used by IT product standardization efforts, but some are different, and successful VIS standardization requires a package of solutions tailored to fit and jointly resolve the specific dilemmas of particular VIS standards initiatives.

Abstract The increasing importance of electronic commerce makes it essential to develop a theory of virtual value chains. This article considers the intermediation process between producers and consumers within electronic markets. We argue that, contrary to existing wisdom, intermediaries will play a key role in electronic markets. Drawing on channel evolution literature and transaction cost economics, we present a set of propositions regarding the emergence of cybermediaries and the development of virtual channel systems.

Social network sites (SNSs) are becoming an increasingly popular resource for both students and adults, who use them to connect with and maintain relationships with a variety of ties. For many, the primary function of these sites is to consume and distribute personal content about the self. Privacy concerns around sharing information in a public or semi-public space are amplified by SNSs’ structural characteristics, which may obfuscate the true audience of these disclosures due to their technical properties (e.g., persistence, searchability) and dynamics of use (e.g., invisible audiences, context collapse) (boyd 2008b). Early work on the topic focused on the privacy pitfalls of Facebook and other SNSs (e.g., Acquisti and Gross 2006; Barnes 2006; Gross and Acquisti 2005) and argued that individuals were (perhaps inadvertently) disclosing information that might be inappropriate for some audiences, such as future employers, or that might enable identity theft or other negative outcomes.

Metrics aresine qua non for solid research, and scientific metrics have now been advanced with new approaches in the arena of Net-enablement (NE), otherwise known as e-commerce. Questions that likely require additional attention include: (1) Where/what is the real value in substituting information for physical processes?, (2) which NE systems effectively support end-to-end fulfillment?, and (3) when should a Net-enabled organization share information? With respect to extant studies in Net-enhancement, the field has been advanced in three methodological dimensions. Multiple methods have been used to validate measures. Approaches to metrics using archival/secondary data have also been initiated. Finally, strong external validity has been established through large scale data gathering.

ABSTRACT In this post dot-com era, much e-commerce activity now arises from established firms with traditional physical outlets. Despite the growth in such click and mortar approaches to e-commerce, little research has specifically addressed this common business model. This article focuses on the underlying dynamics of click and mortar e-commerce businesses using a framework that outlines the potential synergies arising from the integration of e-commerce with traditional channels. Research and theory from such areas as transaction cost economics, interorganizational systems, competitive strategy, and economic sociology are used to develop the click and mortar framework. It details the sources of synergy, the management interventions that can help firms avoid damaging channel conflicts, and the types of benefits yielded by integrated click and mortar approaches. The framework is applied to a specific click and mortar case, an electronics retailer, in order to demonstrate its explanatory value. The heuristic value is demonstrated by deriving several example propositions to guide future empirical work.
