In this paper, we explore how privacy settings and privacy policy consumption (reading the privacy policy) affect the relationship between privacy attitudes and disclosure behaviors. We present results from a survey completed by 122 users of Facebook regarding their information disclosure practices and their attitudes about privacy. Based on our data, we develop and evaluate a model for understanding factors that affect how privacy attitudes influence disclosure and discuss implications for social network sites. Our analysis shows that the relationship between privacy attitudes and certain types of disclosures (those furthering contact) are controlled by privacy policy consumption and privacy behaviors. This provides evidence that social network sites could help mitigate concerns about disclosure by providing transparent privacy policies and privacy controls.

Improving search interfaces and algorithms are major foci of HCI and information retrieval (IR) research respectively. However, less attention has been given to understanding how users collect, manage, organize, and share the results they find from conducting searches on the Web and designing tools to support their needs. In this paper, we present results from a study in which we interviewed 30 people in three cohorts (academic researchers, corporate workers, and people looking for medical information) about their current practices conducting, managing, and sharing information from ongoing, exploratory searches. We report results on users' current practices, tool use, areas of difficulties and associated coping strategies with emphasis on how information seekers use a variety of "tools-at-hand" beyond search engines and web browsers as they search, process, and share results, and on the learning processes that occur as they seek and use information over time.

In this article, we present findings from a survey of nearly 600 university employees' e-mail use. The study provides a detailed comparison of use patterns between work and personal e-mail accounts. Our results suggest that users engage in more "keeping" behaviors with work e-mail than with personal e-mail-respondents reported more frequent use of keeping actions and larger inbox sizes for their work accounts. However, we found correlations between individual respondents' e-mail behaviors in the two contexts, indicating that personal preferences can play a role. We also report results pointing to e-mail as an important boundary management artifact. We show evidence that the use of multiple e-mail accounts may be a work-personal boundary placement strategy, but also observe that a fair amount of boundary permeation occurs through e-mail. To our knowledge, this study is one of the first to compare e-mail use in both work and personal contexts across the same sample. Our findings extend prior research on personal information management regarding e-mail use, and help inform the role of e-mail in managing work-personal boundaries. The results have implications for the design of e-mail systems, organizational e-mail policies, user training, and understanding the impacts of technology on daily life.
