The role of enterprise systems standardization on data breach occurrence
No full textThis study examines the relationship between enterprise systems standardization and data breach occurrence. We argue that the greater degree of compatibility resulting from sourcing enterprise systems modules from fewer vendors (i.e., higher enterprise systems standardization) enables easier management of the implemented modules and creates less cybersecurity risks. To test our hypothesis, we use a panel dataset from 2007 to 2017 constructed from the Aberdeen Computer Intelligence Technology Database, Advisen Cyber Loss Database, and Compustat. We find enterprise systems standardization to be negatively related to data breach occurrence. However, when we drill down to different data breach types, we only find enterprise systems standardization to be negatively related to data breaches that are caused by perpetrators external to the firm or data breaches that involve the compromise of individuals’ data. To address endogeneity concerns, we implement an instrumental variable approach which allows us to be more confident that our results better represent a causal relationship. While there is no conclusive evidence that indicates whether sourcing enterprise systems modules from fewer vendors is generally advantageous or disadvantageous, to the best of our knowledge, our findings suggest that sourcing modules from fewer vendors is, at least, advantageous from a cybersecurity standpoint.Business, Sauder School ofManagement Information Systems, Division ofGraduat
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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Role of heuristics and biases in information security decision making
No full textInadvertent and Irrational human errors (e.g., clicking on phishing emails) have been the primary cause of security breaches in recent years. It has been estimated that these errors are a source of approximately 84% of all breaches in 2017 (Sher-Jan, 2018). To understand the root cause of these errors and examine practical solutions for personal users, I applied the theory of bounded rationality (Simon, 1972, 2000). In the second chapter, I examined the role of several factors (i.e., objective knowledge, subjective knowledge, and default security level) on how secure a decision made by a personal user is (i.e., security level of user’s decision). I discovered that the default security level has the most significant influence on the security level of a user’s decision. Furthermore, the results illustrated that subjective security knowledge mediates the impact of objective security knowledge on security decisions. In Chapter 3, I explored the role of heuristics (i.e., short mental processes) in security decision making. Interviews conducted reveal that users rely on various heuristics to simplify their decision making. Specifically, users rely on experts’ comments (i.e., expertise heuristic), information at hand, such as recent events (i.e., availability heuristic), and security-representative visual cues (i.e., representativeness heuristic). Findings also showed the use of other heuristics, including affect, brand, and anchoring, to a lesser degree. In Chapter 4, I examined the impact of several nudging strategies by using the most prevalent heuristic cues discovered in Chapter 3 and the construal level (i.e., level of abstraction) of messages on users’ security decisions. Using the security level of settings and password entropy as measures of the overall degree of security, users made more secure decisions in the presence of any of the heuristic cues irrespective of the construal level compared to the baseline group (i.e., no-message group). Additionally, with respect to the security level of settings, low-level construal availability, low-level construal representativeness, and high-level construal expertise had the highest impact. For password entropy, low-level construal availability and low-level construal representativeness were also the most effective combination. However, there was no significant difference between high-level and low-level construal expertise conditions.Business, Sauder School ofManagement Information Systems, Division ofGraduat
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
