Social network theory has produced conflicting results regarding the link between different social network structures-bridging versus bonding-and idea generation. To address this conundrum, we conduct a naturally occurring quasi-experiment of 126 open and 108 closed groups within an Enterprise Social Media (ESM) system of a multinational enterprise. Our findings show that idea generation occurs when the type of social network structure-bridging or bonding-is matched to a group's openness or closedness, respectively. We further show that the reverse is counterproductive: when closed groups display bridging ties and open groups display bonding ties, idea generation is significantly undermined. Theoretically, these findings clarify the conditions and mechanisms by which both bridging and bonding can result in idea generation and provide a deeper understanding of the use of ESM for idea generation. Practically, our findings provide valuable and actionable insights regarding the use of ESM for idea generation in groups.

It has been widely known that employees pose insider threats to the information and technology resources of an organization. In this paper, we develop a model to explain insiders' intentional violation of the requirements of an information security policy. We propose sunk cost as a mediating factor. We test our research model on data collected from three information-intensive organizations in banking and pharmaceutical industries (n=502). Our results show that sunk cost acts as a mediator between the proposed antecedents of sunk cost (i.e., completion effect and goal incongruency) and intentions to violate the ISP. We discuss the implications of our results for developing theory and for re-designing current security agendas that could help improve compliance behavior in the future.

This paper investigates the impact of the characteristics of information security policy (ISP) on an employee's security compliance in the workplace. Two factors were proposed as the antecedents of employees' security compliance: ISP Fairness and ISP Quality. ISP Quality is comprised of three quality dimensions--Clarity, Completeness, and Consistency. It is shown that ISP fairness has a strong positive effect on an employee's ISP Compliance. In addition, it is found that ISP quality does not only have a strong positive influence on an employee's ISP compliance but also have a strong influence on an employee's perceived ISP fairness. This study contributes to the literature by highlighting the importance of ISP characteristics; namely, ISP quality and ISP fairness as an organizational resource to enhance an organization's information security.
