ABSTRACT Whistleblowing reports, if properly investigated, facilitate the early detection of fraud. Although critical, investigation-related decisions represent a relatively underexplored component of the whistleblowing process. Investigators are responsible for initially deciding whether to follow-up on reports alleging fraud. We report the results of an experimental study examining the follow-up intentions of highly experienced healthcare investigators. Participants, in the role of an insurance investigator, are asked to review a whistleblowing report alleging billing fraud occurring at a medical provider. Thus, participants are serving as external investigators. In a between-participant design, we manipulate the report type and whether the caller previously confronted the wrongdoer. We find that compared to an anonymous report, a non-anonymous report is perceived as more credible and follow-up intentions stronger. We also find that perceived credibility fully mediates the relationship between report type and follow-up intentions. Previous confrontation is not significantly associated with either perceived credibility or follow-up intentions. Data Availability: Data are available upon request.

Critical Investigation

The study of computing infrastructures has grown significantly due to the rapid proliferation and ubiquity of large-scale IT-based installations. At the same time, recognition has also grown of the usefulness of such studies as a means for understanding computing infrastructures as material complements of practical action. Subsequently the concept of “infrastructure” (or “information infrastructures,” “cyberinfrastructures,” and “infrastructuring”) has gained increasing importance in the area of Computer-Supported Cooperative Work (CSCW) as well as in neighboring areas such as Information Systems research (IS) and Science and Technology Studies (STS). However, as such studies have unfolded, the very concept of “infrastructure” is being applied in different discourses, for different purposes, in myriad different senses. Consequently, the concept of “infrastructure” has become increasingly muddled and needs clarification. The chapter presents a critical investigation of the vicissitudes of the concept of “infrastructure” over the last 35 years.

Abstract In the article KYKA / 1984 is studied as a concrete experiment with the printed book as a medium and with the double-book-format. Karin Moe is in this text dealing with questions concerning the relationship between work and text, and between work, text and reader. The article is an exploration of the design and the composition of the book, and it also explores several kinds of transtextuality, which are establishing interconnections with other literary works and genres. Questions raised by Moe in KYKA / 1984 concerning language and gender are also examined. An important objective of the article is to uncover how and why an experimental and critical investigation is carried out in a book copying a well-known commercial format.

Critical Investigation

As Ted Becker and Christa Slaton affirm in their introduction to The Future of Teledemocracy, this is not “just another book” of scholarly reflection but, rather, an account of “a way of life” (p. xii) in which they have played a central role. Consequently, instead of a detached, critical investigation of the dynamic encounter among technology, communication, and democratic politics, or even a dispassionate appraisal of the implications of a particular aspect of this encounter, what we receive in this book is an intimate digest of Becker and Slaton's 23-year “odyssey” on behalf of their own vision of teledemocracy—complete with “true blue allies” and powerful enemies “who opposed our ideology and had the means to halt our experiments” (p. xi)—framed by a futurist manifesto that unfortunately diminishes the contribution made by the chronicle of the authors' crusade.

Critical Investigation

Stiction is one of the most important and almost unavoidable problems in MEMS, which usually occurs when the restoring forces of the microstructures are unable to overcome the interfacial forces. Stiction could compromise the performance and reliability of the MEMS devices or may even make them malfunction. One of the pivotal process of advancing the performance and reliability of MEMS is to comprehend the failure modes and failure mechanisms of these microdevices. This article provides a critical investigation on the stiction failure mechanisms of the micromachined electrostatic comb-drive structures, which is significant to improve the reliability of microdevices, especially for microfilters, microgrippers, microaccelerometers, microgyroscopes, microrelays, and so on.
