Abstract
Social Network Sites (SNSs) have doubtlessly altered the way that social actors communicate and interact worldwide. Several researches have shown that users disclose personal information within SNSs, while expressing privacy concerns. Users’ inability to protect their privacy within SNSs, despite their recorded privacy concerns, constitutes the core of “Privacy Paradox” and leads to privacy breaches or risks for themselves and other users. In order to reverse or at least minimize users’ disclosure behavior so as to protect themselves, researches underline the need for privacy awareness increase, focusing on the crucial role of education towards this. This research aims to explore the effects of a long-term University-based educational intervention for enhancing students’ digital knowledge and skills in order to protect their privacy in SNSs efficiently. The findings are encouraging regarding students’ privacy awareness enhancement and protection strategies adoption.

Abstract
Social Network Sites have doubtless become part of our lives, facilitating communication and interaction between social actors. Within this frame users disclose personal information for several reasons while at the same time they express privacy concerns. “Privacy Paradox” reveals that despite privacy concerns, users, most of the times, fail to protect their privacy within SNSs, putting thus themselves and other users to risk. In this respect, several researches have shown that users’ privacy awareness increase is of major importance, focusing on the crucial role of education towards this. This research aims to explore the effects of a long-term University-based educational intervention for enhancing students’ digital knowledge and skills in order to protect their privacy in SNSs efficiently. The educational intervention centered on a semester course of a Greek University, provides encouraging findings regarding students’ privacy awareness enhancement.

Abstract
Previous1 literature indicates that SNSs users, and especially Facebook ones, are willing to share information and consequently "sacrifice" their digital privacy in order to obtain bonding or bridging social capital. Additionally, most of the previous research has been administrated to young adults or college students in USA, disregarding the interactional dynamics of these concepts that result in users' sharing on SNSs. This paper attempts to identify their correlation through an exploratory survey administrated to a Greek working adult population using Facebook in particular, while taking into consideration intermediary factors during their decision-making disclosure process. Findings show that perceived social capital has a greater impact on FB self-disclosure than privacy concerns, indicating that self-disclosure comprises an important factor to explore and interpret this relationship in order for further understanding of users' behaviors on FB to be achieved.

Abstract
This paper explores the relationship between Facebook users' self-disclosure, privacy concerns about their digital privacy and the anticipated benefits in social capital. Previous research has shown a positive relationship between Facebook usage intensity and users' perceptions of social capital. However, only few researches to date have tested these correlations empirically, showing how users' self-disclosure practices and digital privacy concerns interact with their anticipated benefits of social capital. To address this issue, an online survey was conducted, administrated to the staff of the University of the Aegean in Greece. The findings indicate that Facebook intensity use, self-disclosure and social capital are positively associated; privacy concerns affect users' disclosure though social capital benefits effect is greater.
