No full textThesis (Ph.D.)--University of Washington, 2014University of Washington Abstract The Role of Trait Affect in the Information Security Behavior of Home Users Marc J. Dupuis Chairs of the Supervisory Committee: Research Associate Professor Barbara Endicott-Popovsky Associate Professor Hazel Taylor The Information School Computers provide people with the means to perform a wide range of tasks, from running complex applications to storing photographs. The Internet adds an additional dimension; it enables people to shop for gifts, pay bills, perform research, read the news, and communicate with old friends and new. In addition to all of the benefits computers provide to people, there are inherent risks. These risks exist in many different forms, including malware, phishing scams, loss of data, and the privacy of individuals being compromised. Home users represent the largest segment of Internet users and pose the most significant threat. However, research has traditionally focused on users within an organizational setting. While research examining home users has increased significantly over the last several years, there is still a lot that we do not know. This research examined the role trait affect, a lifelong and generally stable type of affect, has on the information security behavior of home users in response to three threats: computer performance compromise, personal information compromise, and loss of data and files. In this study, the role of trait affect in the information security behavior of home users was examined by using the two higher order dimensions of affect, positive affect and negative affect, which represent the valence of mood descriptors (e.g., afraid, scared, nervous, guilty, active, alert, enthusiastic, excited). It was hypothesized that the effect trait positive affect and trait negative affect have on the information security behavior of home users is indirect through their effect on threat perception (i.e., perceived threat severity and perceived threat vulnerability) and self-efficacy. Likewise, it was hypothesized that higher levels of trait positive affect are associated with lower levels of threat perception and higher levels of self-efficacy, with trait negative affect having the opposite effect. Three surveys were used to explore these issues, including a previously validated survey instrument for trait positive affect and trait negative affect, previously validated constructs adapted from other research, and measures for the dependent variables developed through use of the Delphi technique. The results of the three surveys supported 10 of the 33 hypotheses. Out of the nine hypotheses for trait positive affect, three were supported. This included an association between higher levels of trait positive affect with higher levels of information security response self-efficacy in two of the three studies. In one of the surveys, higher levels of trait positive affect was also associated with lower levels of perceived threat vulnerability. In contrast, none of the nine hypotheses for trait negative affect were supported. Beyond the 18 hypotheses for trait affect, the hypothesized relationship between self-efficacy and information security behavior was supported in all three surveys. Five additional hypotheses based on Protection Motivation Theory (PMT) were also supported. This research makes five primary contributions. First, trait positive affect may play an indirect role in understanding how individuals respond to and cope with a threat. Furthermore, it suggests that trait positive affect is worth exploring further, perhaps with greater granularity than what was done here. Second, this research extended the application of Protection Motivation Theory (PMT), which has been the primary underlying theory used by researchers in understanding the information security behavior of home users. In part, this was done by including constructs from PMT and measurements of trait affect to form a more complete understanding of the information security behavior of home users. Third, in addition to extending PMT, this research examined three different threats using the same methods and data analysis procedures. I did this by conducting three different surveys at the same time--one for each of the three threats. This allowed me to determine if the efficacy of PMT depended at least in part on the threat under examination. The data analysis suggests that the specific threat that is examined using PMT does impact the efficacy of PMT as a theoretical framework for understanding human behavior. Fourth, an additional contribution this research makes is its support for the continued role of self-efficacy as a predictor of behavior. In fact, the positive association between self-efficacy and behavior was the one general hypothesis that was supported in all three surveys. Fifth, this dissertation contributes to research on the information security behavior of home users by having developed and validated three survey instruments. These three survey instruments were designed to measure specific information security responses required to mitigate one of three different threats: computer performance compromise, personal information compromise, and loss of data and files. Finally, I explored future research avenues in light of these results, including experimental research, as well as exploring trait positive affect with a higher level of granularity than what was done here. Implications for theory, policy, and practice are discussed

A methodology for calibrating forensic ready, low layer network devices /by Barbara Endicott-Popovsky.
No full textThis dissertation presents a methodology for calibrating low layer network devices. The research is motivated by the probability that as courtroom admissibility requirements become important considerations for networked systems, the demand for forensically ready systems over costly and non-scalable ad hoc digital forensic investigations will necessitate a change in network protection strategies and design, including calibration of low layer network devices used to collect forensic data in networks. The work draws from a well-established theoretical approach to penetration testing. The calibration approach described in this dissertation is a compilation of four separate projects that include verification testing of a low layer network device, the development of a generalized framework for calibrating low layer network devices, the application of the framework to calibrating a specific low layer network device, and the evaluation of the calibration protocol for completeness.;The contributions of this research provide a foundation for developing a calibration standard for low layer network devices, where none currently exists. It is part of a larger research direction that explores the development of a methodology for embedding forensics in networks.Thesis (Ph. D., Computer Science)--University of Idaho, June 2007

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
