Who wins in a Data Breach? A comparative Study on the intangible costs of Data Breach Incidents
No full textOver the years data breaches have become a status quo due to an attacker’s repeated ability to successfully infiltrate networks. 2015 was no stranger to these cases. Victims included millions of customers of Anthem, BlueCross BlueShield, Experian/T-Mobile, and Office of Personnel Management, all of whom lost confidential data. Needless to say, data breaches have a significant impact on the financial performance and reputation of firms. Collectively, the majority of the previous security studies on breach announcements have used event study methodology. These studies have focused on the change in market value of the company within a few days of the security breach announcements and concluded that there is a negative impact. But what is the impact of negative publicity due to a data breach on an organization’s reputation? How should that be gauged? In this study we compare the financial impact with the reputational damage of data breaches. We performed two event studies: an event study on stock prices and additionally a sentiment event study applied on social media data. In contrast to previous research, shareholders do not react negatively to data breach announcements, whereas the impact on reputation is statistically significant as negative

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
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
Critical success factors for an effective security risk management program in an organization: An exploratory case study
No full textThis item is available only to currently enrolled UTSA students, faculty or staff. To download, navigate to Log In in the top right-hand corner of this screen, then select Log in with my UTSA ID.This study investigates differences in perception between layers of management (executive, middle, and lower) and staff with regard to the influence of critical success factors (CSFs) on security risk management (SRM) effectiveness. This is an in-depth case study conducted at a Fortune 500 company. Rockart's (1979) CSF method is modified through the use of Kahn et al's (1964) role theory. Role theory tenets such as role consensus, role compliance, communication, role conflict, and role ambiguity form the basis of introducing six initial CSFs. The initial CSFs are executive management, organization maturity, open communication, risk management stakeholders, team member empowerment, and holistic view of organization. Initial CSFs along with three additional CSFs (security maintenance, corporate security strategy, and human resource development) are confirmed to exist in the organization through interviews with select management and staff employees.
Employing ordinary least squares regression using dummy variables from responses of a validated survey, the study shows that management and staff agree that each of the nine CSFs are important for SRM effectiveness. However, they differ on the level of importance of each CSF. With regard to six of the nine CSFs (executive management support, organization maturity, open communication, holistic view of organization, corporate security strategy, and human resource development), management and staff concur on their current implementation practices and have a positive perception regarding their impact on SRM effectiveness. However, more importantly, the results also indicate that both management and staff are not satisfied with the current practices pertaining to risk management stakeholders, team member empowerment, and security maintenance. Recommendations are provided for improving the practices associated with these three CSFs.Information Systems and Cyber Securit
