The Critical Role Of Ethical Leadership In Employees’ Information Security Behaviors: A Two-Study Approach, Botong Xue

Theses and Dissertations

Employees’ information security policy (ISP) related behaviors have been paid attention by previous studies in the past decades. Among different factors that are influential on employees’ ISP behaviors, different leadership styles have been tested under the information security context; however, as one leadership style that is highly related to employees’ positive organization behaviors, the role of ethical leadership has been largely overlooked under the information security context. In addition, most research in the past decades overly focused on employees’ performance on ISP in-role behaviors, including ISP compliance and violation behaviors, where extra-role behaviors – security behaviors that are beneficial to …

The Moderating Effect Of Media Naturalness On Motivating Language, James Cox

Theses and Dissertations

For decades, the research in communication in organizational behavior has focused on the reduction of uncertainty and consequently so has the research of leadership and computer mediated communication (CMC) (Salancik & Pfeffer, 1977; Sullivan, 1988). Because of this, many of the controversial issues and competing theories of CMC that have in good part centered around the topic of media choice in the context of task performance, which is a reflection of this narrow focus of CMC on uncertainty reduction. Therefore in order to study the more whole form of communication in motivation proposed by Sullivan (1988), a CMC theory is …

Good Game, Greyory Blake

Theses and Dissertations

This thesis and its corresponding art installation, Lessons from Ziggy, attempts to deconstruct the variables prevalent within several complex systems, analyze their transformations, and propose a methodology for reasserting the soap box within the display pedestal. In this text, there are several key and specific examples of the transformation of various signifiers (i.e. media-bred fear’s transformation into a political tactic of surveillance, contemporary freneticism’s transformation into complacency, and community’s transformation into nationalism as a state weapon). In this essay, all of these concepts are contextualized within the exponential growth of new technologies. That is to say, all of these semiotic …

Reducing Sepsis Mortality: A Cloud-Based Alert Approach, Janet A. Zink

Theses and Dissertations

The aim of this study is to examine the impact of a cloud-based CDS alerting system for SIRS, a precursor to sepsis, and sepsis itself, on adult patient and process outcomes at VCU Health System. The two main hypotheses are: 1) the implementation of cloud-based SIRS and sepsis alerts will lead to lower sepsis-related mortality and lower average length of stay, and 2) the implementation of cloud-based SIRS and sepsis alerts will lead to more frequent ordering of the Sepsis PowerPlan and more recording of sepsis diagnoses. To measure these outcomes, a pre-post study was conducted. A pre-implementation group diagnosed …

Social Engineering Knowledge Measured As A Security Countermeasure, Christopher Artejus Sanders

Theses and Dissertations

Social Engineering has become a significant threat to the security of business, government, and academic institutions. As vulnerabilities to social engineering attacks increase, organizations must incorporate risk mitigation strategies to their portfolios of Information Systems Security Countermeasures (ISSC). The goal is to implement mitigation strategies that balance the cost of implementation, the privacy of employees, and the resulting expected costs of social engineering attacks. In this paper we develop an analytical model that calculates the total cost of protection, including the trade-off between the cost of implementing protection strategies and the resulting expected cost of social engineering attacks. We use …

Automatically Detecting The Resonance Of Terrorist Movement Frames On The Web, Ugochukwu O. Etudo

Theses and Dissertations

The ever-increasing use of the internet by terrorist groups as a platform for the dissemination of radical, violent ideologies is well documented. The internet has, in this way, become a breeding ground for potential lone-wolf terrorists; that is, individuals who commit acts of terror inspired by the ideological rhetoric emitted by terrorist organizations. These individuals are characterized by their lack of formal affiliation with terror organizations, making them difficult to intercept with traditional intelligence techniques. The radicalization of individuals on the internet poses a considerable threat to law enforcement and national security officials. This new medium of radicalization, however, also …

Divergence In Stakeholder Perceptions Of Security Policies: A Repgrid Analysis For Norm-Rule Compliance, Ahlam Almusharraf

Theses and Dissertations

Many organizations have a problem with synchronizing individual values regarding information security with expectations set by the relevant security policy. Such discordance leads to failure in compliance or simply subversion of existing or imposed controls. The problem of the mismatch in understanding the security policies amongst individuals in an organization has devastating effect on security of the organization. Different individuals hold different understanding and knowledge about IS security, which is reflected on IS security policies design and practice (Vaast, 2007). Albrecthsen and Hovdena (2009) argue that users and managers practice IS security differently because they have different rationalities. This difference …

In addition to several types of extrinsic motives noted in prior studies, including sanctions, rewards, and social pressures, this study adds that an important contributing intrinsic factor is empowerment. Per Thomas and Velthouse’s (1990) intrinsic motivation model, empowerment is the positive …

Theorizing When User Reaction To It Implementation Is Neither Resistance Nor Acceptance, But Constructive Behavior: A Case Study Of Healthcare It Implementation, Kaveh Mohajeri

Theses and Dissertations

The prevailing discourse of “resistance vs. acceptance” in IT implementation research mostly personalizes the issue as “users” versus IT implementers (e.g., managers, CIOs, CMIOs, etc.). This kind of discourse has created an IT-implementer-centric attitude among IS scholars and practitioners. The IT-implementer-centric attitude, while embraces “acceptance” as a desirable reaction almost unconditionally, frequently holds for minimizing or more conservatively suppressing “resistance” to IT implementation. In other words, the mainstream IT implementation research, almost completely, treats “users” as passive recipients whose choices, as they face pre-developed/pre-designed/pre-rolled-out technology being implemented, can only be defined on a spectrum from “acceptance” to “resistance.” The current …
