In addition to end-user issues, this work also looks at computer security within the context of human activity and user issues. The book's 18 chapters are written by international contributors, mainly from the US, in areas such as management, business information systems, and information technology. The book begins with an extensive preface reviewing issues related to user involvement in information systems, information security, and knowledge management systems, and also explaining Michael Polyani's taxonomy of knowledge, Blackler's taxonomy of knowledge, and social theory and the web. Consumer trust is one theme cutting across several of the book's chapters, with discussion of trust restoration in electronic commerce and the relationship between self-efficacy and consumer trust. Other topics investigated include delivery and payment options for online retailing, an end-user authentication model, technology acceptance in the US Navy's combat information system, and errors in operational spreadsheets. Further areas explored include supporting computer workers, the effects of distraction and task complexity in mobile computing environments, and leveraging and mitigating the access and immediacy of social media and information technologies.
