In the digital era, a plethora of information that we are using is digitized. By using the digital information, people can obtain a lot of benefits such as sharing information easily through Social Network Service (SNS), saving time by handling digitalized data or improving job practices using digitized information. However, negative unexpected outcomes also exist such as indiscriminate digital information sharing, mishandling of digital information, or potential privacy issues etc. Without knowing about the characteristics of digital information, achieving benefits of using digital information and reducing the negative consequences of using digital information is difficult. In this thesis, we study digital information management. This dissertation is composed of three essays focusing on digital information issues in the context of crises and insiders. Specifically, we focus on three contexts of digital information management 1) social media 2) organizational and 3) ethical context. The first essay explores digital information diffusion issues through SNS during extreme events. We examine the role of tweet features such as reaction time, number of followers, and usage of hashtag, message types (rumor related and non-rumor related) on the diffusion of digital information during the 2013 Boston marathon tragedy. The results shows that the number of followers shows a positive relationship with message diffusion. However, the relationship between tweet reaction time and message diffusion is negative. Finally, tweet messages that do not include hashtags diffuse more than messages that contains hashtags. This essay contributes by adapting the innovation diffusion model to explore characteristics of digital information that impact on diffusion in social media context during extreme events. The second essay investigates insider’s perceptions regarding information assurance (sensitive digitized data) in the organizational context (financial Institutions). Applying Routine Activity Theory (RAT), this essay develops a risk assessment model for examining the factors that affect employees’ perceptions of risk regarding the breaches of digital information. Our analyses show that perception of value, inertia, and accessibility of targeted digitized information (sensitive data) along with presence of guardians have an impact on perception of risk about sensitive data breach in financial institutions. Moreover, the amount of information (both online and offline) available regarding the data influence the relationship between value of the sensitive data and suitability for data breach. The third essay deals with judgement about ethical use of digital information in the context of law enforcement agents. We focus on digital evidence management of Police Body Worn Camera (BWC) that has been considered as a very new technology in the law enforcement domain. We develop a research model to explore the determinants that impact police officers’ judgment about ethical use of digital evidence of BWC. The results show that Interactional justice and police subculture are positively associated with police job satisfaction. Further, perceived risk of using BWC and job satisfaction are negatively related with police officers’ concerns about ethical use of BWC. Understanding such determinants will assist in development of policies and help in the provision of actionable guidelines.
