The central goal of this project is to better understand the relationship between civil war and repression at each phase of the "civil-war life-cycle," which is composed of the escalation and onset of civil war, the war itself, and the post-war period. The project then seeks to understand the role of repression in civil war onset, where repression is argued to be either a permissive condition or a direct cause of civil war, where the role of repression is tied to what type of civil war occurs. As a permissive condition, repression essentially provides the opportunity for a group to carry out an attack, invasion, mutiny, and the like. During other conflicts, repression may be a direct cause of the war. The repression of protest movements may lead those groups to view "normal," non-violent political channels as closed, while also increasing grievances and therefore their willingness to fight. This direct mechanism along with the escalation process that leads to civil war is explored in depth, using data from the 2011 Arab Spring. This project also seeks to explain when conflicts are likely to be accompanied by harsh repression and the targeting of civilians, and to address whether that strategy is effective. It is argued that insurgencies rely on civilian populations for material and non-material support; if the government targets this resource pool then it may be able to undercut that lifeline and thus the military effectiveness of the group. Yet, as repression is costly this is only a strategy likely to be employed when the rebels are gaining ground, when they are relatively strong and militarily effective. As such, governments that employ repression as a war-time strategy are likely beginning from a point of weakness or disadvantage. It is thus further argued that the "gamble" of repression is not likely to reverse the government's fortunes; rather, wars marked by high levels of repression are most likely to end in stalemate. Finally, the use of, or the restraint from using, repression in post-war periods is also explored. Little attention has thus far been paid to the use of repression in post-conflict states, despite the growing literature on the consequences of conflict and the importance of this time for rebuilding and establishing peace. Here, the transformation of the war-time threat, together with various constraints against using repression in the post-war period, are considered.

Web browsers are increasingly designed to be extensible to keep up with the Web's rapid pace of change. This extensibility is typically implemented using script-based extensions. Script extensions have access to sensitive browser APIs and content from untrusted web pages. Unfortunately, this powerful combination creates the threat of privilege escalation attacks that grant web page scripts the full privileges of script extensions and control over the entire browser process. This thesis describes the pitfalls of script-based extensibility based on our study of the Firefox Web browser, and is the first to offer a classification of script-based privilege escalation vulnerabilities. We propose a taint-based system to track the spread of untrusted data in the browser and to detect the characteristic signatures of privilege escalation attacks. We show that this approach is effective by testing our system against exploits in the Firefox bug database and finding that it detects the vast majority of attacks with no false alarms.

ABSTRACT ESCALATION OF COMMITMENT IN INFORMATION TECHNOLOGY PROJECTS: A GOAL SETTING THEORY PERSPECTIVE BY VIJAY KASI Aug 30, 2007 Committee Chair: Dr. Mark Keil Major Academic Unit: Center for Process Innovation Information technology (IT) projects are prone to failure. One explanation for the high failure rate among IT projects is that managers overly commit to a failing course of action, a phenomenon referred as escalation of commitment. While the notion of goals and commitment are central to the phenomenon of escalation, very few prior studies have investigated their impact on escalation. In this study, a research model rooted in goal setting theory is advanced to better understand escalation of commitment of IT project managers. A role-playing experiment with 350 IT managers was used to test the proposed research model. The results of the study suggest that IT managers are more willing to escalate their commitment under the influence of easy and vague goals compared to difficult and specific goals. Initial goal commitment of IT managers and the level of project completion were found to have a significant effect on IT manager’s willingness to continue. Initial goal commitment of IT managers was also found to moderate the relationship between goal difficulty and willingness to continue. In other words, when there is a higher level of goal commitment, an easy goal will have a greater effect in terms of promoting an individual’s willingness to continue.

Information systems project management has historically been a problematic area. One of the reasons for this has been the issue of escalation where resources continue to be committed to a failing course of action. While many causes of escalation have been proposed, this dissertation investigates one possible cause: that the project manager may not hear, ignores or overrules a report of bad news to continue a failing course of action: the Deaf Effect response to bad news reporting. This effect has not been previously studied within the information systems literature. In this dissertation, the Deaf Effect is examined through a series of three laboratory experiments and a case study. It finds that in a conducive environment, where the bad news reporter is not seen as credible, and the risk of project failure is seen as low, decision makers tend to view the report of bad news as irrelevant and thus ignore or overrule the report of bad news and continue the current course of action. Role Prescription of the bad news reporter, illusion of control and a perception of a highly politicized environment are factors that also increase the occurrence of the Deaf Effect.

Web browsers are increasingly designed to be extensible to keep up with the Web's rapid pace of change. This extensibility is typically implemented using script-based extensions. Script extensions have access to sensitive browser APIs and content from untrusted web pages. Unfortunately, this powerful combination creates the threat of privilege escalation attacks that grant web page scripts the full privileges of script extensions and control over the entire browser process. This thesis describes the pitfalls of script-based extensibility based on our study of the Firefox Web browser, and is the first to offer a classification of script-based privilege escalation vulnerabilities. We propose a taint-based system to track the spread of untrusted data in the browser and to detect the characteristic signatures of privilege escalation attacks. We show that this approach is effective by testing our system against exploits in the Firefox bug database and finding that it detects the vast majority of attacks with no false alarms.

The literature on escalation situations and audience costs suggests that democratic executives tend to increase commitment to a foreign policy in response to negative feedback. However, real-world cases from international politics suggest otherwise. Specifically, executives do not appear to respond uniformly to failing situations. While scholars have begun to unravel the audience cost mechanism, up until know, we know little about reasons for the variation in how executives use policy feedback to update commitment to a foreign policy. In this dissertation, I adopt an integrative approach and present a model of sequential decision-making that explains the conditions under which leaders escalate and de-escalate commitment in response to feedback. I attempt to break down the audience cost mechanism to explain why democratic executives do not respond uniformly to negative feedback. While the literature on the escalation of commitment suggests decision-makers tend to increase investment in the face of negative feedback, my theory suggests that under certain conditions, executives may find it politically advantageous to back down from a failing policy. My theory emphasizes the relationship between citizens, executives, and foreign policy effectiveness. Next, I suggest that the foreign policy tool of military intervention provides a suitable test case for a theory of sequential decision-making. I first test hypotheses derived from the theory regarding the preference formation process of democratic citizens during the course of such an episode. Understanding the response of citizens to feedback is an important first step to understanding the updating decisions of democratic executives. While previous work has relied on aggregate survey data, experimentation provides me with the ability to analyze how an individual citizen?s preference over commitment is impacted by policy feedback. The results of the experimental analyses suggest that citizens act as investors: they favor increasing commitment to military interventions when viewing negative feedback, up to a point. I then test the main hypotheses derived from the theory regarding executive decision-making on a dataset of major power military interventions from 1960-2000. Overall, the results support the hypotheses: public approval conditions the manner in which executives use feedback to update intervention commitments. In the conclusion, I summarize the study by highlighting key results, present the broad implications for the study of democratic foreign policy making, and discuss avenues for future research.

Abstract Essentially, In vitro diagnostics (IVD) testing play a key role in early disease detection; effectiveness of patient treatment monitoring throughout the progress of disease and improve decision-making for healthcare system. Several studies have demonstrated that IVD testing result in huge financial and therapeutic benefit. Taiwan IVD market has been growing rapidly in last decade due to launch of National Health Insurance policy¡Bgrowing of geriatric population¡Bimprovement of living quality¡Bconsciousness of personal health. However, this is also driving Taiwan IVD market in a highly competitive market place, it anticipated that the escalation will not only jeopardize the healthcare quality but also affect entire healthcare resources utility and increasing healthcare cost as a whole. The research analyzed the causative of Taiwan In Vitro Diagnostics (IVD) industrial is based on the framework of macroeconomic environment¡Bindustrial organization structure¡Bcompetitive marketing behavior and industrial market performance. The research found that macroeconomic environment for Taiwan IVD industrial is favorable; the industrial is presenting a mild dispersed structure and the causative for escalation was mainly caused from strategic homology among industrial enterprises. In addition to this finding, the research also developed a possibly differentiate strategy to avoid escalation throughout the learning innovation process and enterprise process reengineering as to help industrial enterprises from developing future long term strategy.

In an organisation, escalation of commitment represents behaviour of decision makers who become committed to failing courses of action. This behaviour usually derives from the decision makers’ reluctance to acknowledge their failed action in the initial allotment of time and resources, and thus taking actions to manifest their prior decision were correct and they will be achieving the planned goal.   In a single day of 1996 during a climbing expedition destined to summit Mt Everest, eight people lost their lives, including the climbing team leaders, in part due to the decision made that led to the teams to engage in escalation behaviour.  The climbing teams in the 1996 Mt Everest expedition serve as examples of temporary organisations in an extreme setting. The purpose of the research is to explore insights on the aspects promoting escalation on the Mt Everest tragedy and shed some light into how escalation manifests in temporary organisations. The factors that might be found will be applicable only to this particular case; nevertheless they might contribute on the overall development of how escalation comes about in temporary organisations. The research question of this study is how aspects promoting escalation where present in the 1996 Mt. Everest expedition?   For many years different theories attempted to explain the factors that promote escalation behaviour. The most important theories were combined together into a theoretical framework developed by Staw and Ross (1987a), which contains four major determinants of commitment in escalation: project, psychological, social and organisational. This framework is applied in this qualitative study based on the 1996 Mt Everest case. The study was executed through the analysis of the firsthand accounts of the survivors and observers present on the mountain that year as well as mass media outputs, the framework of escalation was used as an assistance tool for making sense of the findings the research may produce.   The results of the study managed to place the line of events in the determinants framework and identified all four types of determinants of commitment taking place through the progress of the expedition. A new organisational determinant of commitment was found (pursuit of enterprise growth) which yielded significant practical implications and might also lead the way for future research on escalation of commitment in temporary organisations.

Escalation of commitment is the voluntary continuation of investing resources into what appears to be a failing course of action whose outcome is uncertain. Investigation into the escalation of commitment phenomenon is important to organizations because such behavior could result in grave economic loss. This research investigates two cognitive biases that we posit lead to IT escalation of commitment, namely, attribution bias and overconfidence in an escalation decision, as well as desire to rectify past outcomes (DRPO) for its potential role as a mediator. To test our research model, 160 IT managers participated in a web-based role-playing experiment. Attribution was manipulated at two levels (internal and external), creating two treatment conditions. We posited that the participants assigned to the internal attribution condition would escalate their commitment to the failing IT project to a greater extent than participants assigned to the external attribution condition; that individuals that have a high, versus low, level of overconfidence would have a greater tendency to escalate; and that DRPO would mediate the effects of attribution and overconfidence on escalation of commitment. Attribution bias was significant at the .1 level, but in the opposite direction of what was hypothesized; overconfidence showed a significant main effect on escalation. The effect of attribution bias on escalation was significantly mediated by DRPO, but the effect of overconfidence on escalation was not mediated by DRPO. Implications of these findings for both research and practice are discussed.
