There are two main objectives of this thesis. First, to review the social science evidence on the extent to which different police practices have been proven to reduce crime, or not reduce crime, as well as those cases where the evidence is not clear. This thesis synthesizes crime reduction strategies to short-list those practices that are proven to reduce crime. Second, it uses the evidence collected to facilitate an exploratory case study with three key informants from the Ottawa Police Service (OPS). The case study examines the current use and perceived future role of the police in evidence-based crime prevention efforts. Overall, the research study seeks to answer the following four research questions: 1. What sources of literature provide well-researched and reliable data on effectiveness of policing in crime reduction? 2. In this literature, what policing strategies/practices are shown to reduce crime, not reduce crime or are promising in reducing crime? 3. To what extent is the OPS using evidence-based knowledge to guide their policing strategy/practices? 4. To what extent is the OPS open to using evidence-based knowledge to guide their policing strategy/practices in the future?

The artist/teacher identity is often a contentious site in which the two roles are perceived of as in opposition to one another, rendering relationships between the two challenging to negotiate. This thesis explores ways in which identity transformations are navigated. Specifically, I have investigated what it feels like, looks like and means to practice as an artist and a teacher through my art making practice. Culminating in an art exhibition, my work takes the shape of an autoethnographic, arts based inquiry framed by the methodology and renderings of A/r/tography placed within a five phase creative process proposed by Barone and Eisner. This inquiry involved making art work that was provoked by acts of (re) membering and (re) making as I engaged with a lifetime of photographic images while looking for persistent patterns and themes that in turn would illuminate aspects of my fragmented identity.

With declining wild fisheries and increasing seafood demand from a growing population, attention has turned to aquaculture in general, and shellfish aquaculture in particular, to meet this demand. Aquaculture has grown dramatically in the last twenty years through intensification of operations and the expansion of the industry into new areas. This growth has been associated with environmental degradation and social conflict leading some to question its sustainability. However, those studying the problem point to significant opportunities for sustainable forms of aquaculture by focusing on the cultivation of species such as shellfish and the adoption of ecosystem-based management (EBM). Shellfish aquaculture has a long history in British Columbia (B.C.), Canada with an abundance of coastline and suitable water conditions. There is significant development potential for shellfish aquaculture in B.C., which creates an opportunity to ensure this development occurs in an ecologically sound way through the use of governance approaches like ecosystem-based management. Transitioning from conventional approaches to resource management to an ecosystem-based approach presents several challenges particularly for the management of one sector. This study highlights how an understanding of the industry and the existing governance context can inform the implementation of EBM. The specific research objectives include: (1) to understand the governance system for shellfish aquaculture in B.C.; (2) to understand the shellfish aquaculture industry within the context of EBM; and (3) to explore EBM as an approach to governance in the shellfish aquaculture industry in B.C. The main method of inquiry is a questionnaire survey (October 2006 to February 2008) of the shellfish aquaculture industry. Supporting methods include an analysis of industry data, an in-depth analysis of government documents, policies and regulations, and targeted interviews with federal and provincial government regulators. The empirical knowledge gained through the main research instrument was combined with the contextual knowledge gained through the supporting methods to achieve a more holistic understanding of the case study. The results show that the governance setting for the shellfish aquaculture industry is multi-lateral and the lack of comprehensive and targeted legal instruments, and the ill-use of marine spatial planning and conflicts with other coastal users have together contributed to an inefficient and costly site application process. EBM has the potential to address some of these challenges with the current governance process by making some decisions on an ecosystem-scale as opposed to an application-by-application basis, such as assessing the presence of fish habitat and consulting with stakeholders. The results of the survey of the shellfish aquaculture industry show that the industry is geographically diverse, and understands and values the connection between their business and the large ecosystem. This suggests that the industry may be supportive of EBM. However, the industry faces many economic challenges that may influence their capacity to participate, as such regulators should look towards the use of economic incentives to achieve policy objectives. Although this research provided several recommendations for management and the industry in moving forward with this new approach to governance, three fundamental elements are needed: • marine spatial planning that is integrated within the governance framework; • the integration science and management through adaptive management including an ongoing monitoring framework that informs governance strategies; and, • engaging the industry as active partners in this governance approach through co-management. This research makes significant contribution to understanding the shellfish aquaculture industry in B.C. Prior to this study there was little information available characterizing the structure and socio-economic make-up of the industry. The results of the survey and the in-depth analysis of the governance context for the shellfish aquaculture industry provide a previously unavailable base of information from which to build future studies. In addition this research contributes to the growing body of literature on EBM assessing the potential challenges and opportunities for moving the theoretical concept into practice. / Graduate

This thesis examines the special case in which a newly developed dynamic measurement system must be characterized when an accepted standard qualification procedure does not yet exist. In order to characterize this type of system, both physical experimentation and computational simulation methods will be used to build trust in this measurement system. This process of establishing credibility will be presented in the form of a proposed methodology. This proposed methodology will utilize verification and validation methods that apply within the simulation community as the foundation for this multi-faceted approach. The methodology will establish the relationships between four key elements: physical experimentation, conceptual modeling, computational simulations, and data processing. The combination of these activities will provide a comprehensive characterization study of the system. In order to illustrate the methodology, a case study was performed on a dynamic force measurement system owned by Sandia National Laboratories. This system was designed to measure the force required to pull a specimen to failure in tension at a user-input velocity. The results of the case study found that there was a significant measurement error occurring as the pull event involved large break loads and high velocities. 100 pull events were recorded using an experimental test assembly. The highest load conditions discovered a force measurement error of over 100%. Using computational simulations, this measurement error was reduced to less than 10%. These simulations were designed to account for the inertial effects that skew the piezoelectric load cells. This thesis displays the raw data and the corrected data for five different pull settings. The simulations designed using the methodology significantly reduced the error in all five pull settings. In addition to the force analysis, the simulations provide insight into the complete system performance. This includes the analysis of the maximum system velocity as well as the analysis of several proposed design changes. The findings suggest that the dynamic measurement system has a maximum velocity of 28 fps, and that this maximum velocity is unaffected by the track length or the mass of the moving carriage.

This conversation is an invitation to a research and artistic experience engaging in teaching and learning with sensitivity and consideration, and in the course of doing, revealing insights about the transformative processes of becoming-teacher in art education. Invoking the architecture of the contemporary triptych, this installation involves structural frames of arts research processes, practices and products, and iconographic frames of becoming-teacher as unfolding, unexpectedness and uncertainty. I explore how arts research opens possibilities through the act and art of sharing stories and visuals in a triptych which may be read sequentially, or out of order, as a relational experience, entering at any point across and/or within each panel. In doing arts research, I question: What insights are generated through the arts in a case study concerning the lived and learning experiences of women becoming-teachers? How does arts research inform research processes, practices and products? How do I theorize arts research as customary methodological ecotones? Based on this study, a number of key issues are illuminated concerning teacher education. The reconceptualization of teacher education in terms of health and well-being is critical. Emphasis on geographies of self and the evolution of situated knowledges as a means to negotiate becoming-teacher, along with notions of teacher as researcher and collaborative leadership in teacher education, provide a basis for active reform in teacher education. An emotional journey, complex and complicated, rich in artful expressions, this conversation moves between theoretical and methodological considerations and culminates in a series of realizations about becoming-teacher and arts research, honouring the knowledge creation of research partners, and my discoveries and realizations as an arts researcher, to make this expression of arts research an opportunity to share alternate perspectives within teaching culture.
