This research paper seeks to understand how and why practitioners of Crime Prevention Through Environmental Design (CPTED) exercise rational and strategic forms of social control over their clients. Based on data gathered from semistructured interviews and myriad documents, I argue that practitioners frame (Goffinan, 1974) crime related risks in ways that render the application of CPTED a rational and prudent course of action while at the same time establishing the professional legitimacy of their expertise. Moreover, I argue that this dynamic not only reflects the socioeconomic conditions inherent in risk society, but also sheds light on contemporary forms of governmentality. I conclude by suggesting that CPTED may actually undermine our ability to engage those unlike ourselves in meaningful political dialogue while at the same time individualizing what is essentially a structural social problem. / Thesis / Doctor of Philosophy (PhD)

In the current Navy environment of undersea weapons development, the engineering aspect of design is decoupled from the development of the tactics with which the weapon is employed. Tactics are developed by intelligence experts, warfighters, and wargamers, while torpedo design is handled by engineers and contractors. This dissertation examines methods by which the conceptual design process of undersea weapon systems, including both torpedo systems and mine counter-measure systems, can be improved. It is shown that by simultaneously designing the torpedo and the tactics with which undersea weapons are used, a more effective overall weapon system can be created. In addition to integrating torpedo tactics with design, the thesis also looks at design methods to account for uncertainty. The uncertainty is attributable to multiple sources, including: lack of detailed analysis tools early in the design process, incomplete knowledge of the operational environments, and uncertainty in the performance of potential technologies. A robust design process is introduced to account for this uncertainty in the analysis and optimization of torpedo systems through the combination of Monte Carlo simulation with response surface methodology and metamodeling techniques. Additionally, various other methods that are appropriate to uncertainty analysis are discussed and analyzed. The thesis also advances a new approach towards examining robustness and risk: the treatment of probability of success (POS) as an independent variable. Examining the cost and performance tradeoffs between high and low probability of success designs, the decision-maker can make better informed decisions as to what designs are most promising and determine the optimal balance of risk, cost, and performance. Finally, the thesis examines the use of non-dimensionalization of parameters for torpedo design. The thesis shows that the use of non-dimensional torpedo parameters leads to increased knowledge about the scaleability of torpedo systems and increased performance of Designs of Experiments. The integration of these ideas concerning tactics, robust design with uncertainty, and non-dimensionalization of torpedo parameters has lead to the development of a general, powerful technique by which torpedo and other undersea weapon systems can be fully optimized, thereby increasing performance and decreasing the total cost of future weapon systems.

For companies that develop and operate IT applications that process the personal data of customers and employees, a major problem is protecting these data and preventing privacy breaches. Failure to adequately address this problem can result in considerable damage to the company's reputation and finances, as well as negative effects for customers or employees (data subjects). To address this problem, we propose a methodology that systematically considers privacy issues by using a step-by-step privacy impact assessment (PIA). Existing PIA approaches cannot be applied easily because they are improperly structured or imprecise and lengthy. We argue that companies that employ our PIA can achieve "privacy-by-design", which is widely heralded by data protection authorities. In fact, the German Federal Office for Information Security (BSI) ratified the approach we present in this article for the technical field of RFID and published it as a guideline in November 2011. The contribution of the artefacts we created is twofold: First, we provide a formal problem representation structure for the analysis of privacy requirements. Second, we reduce the complexity of the privacy regulation landscape for practitioners who need to make privacy management decisions for their IT applications.
