This dissertation examines how information technology can help acquirers to improve the performance of their acquisition targets. An acquisition creates value when the acquirer can generate more returns from the acquired business than its former owner can, a condition we call the acquirer's parenting advantage. Then, we introduce two IT-related sources of parenting advantage. Acquirers with more extensive process digitization can provide richer digitized resource to serve their newly acquired businesses, and acquirers with more related process digitization can unlock more synergies between the newly acquired and existing business units. So, as we argue, digitization extensiveness enables a digitization-revitalization mechanism for acquisition value creation, and digitization relatedness enables an integration-synergy-creation mechanism. Both mechanisms can be carried out through digital accommodation activities after acquisitions. Furthermore, the digitization gap between acquirers and targets is a major contingency for digital accommodation, with the second mechanism functioning mostly when the target has already had advanced digitization achievements. We empirically validated these hypothesized relationships by tracking the IT and performance changes in 109 U.S. hospitals before and after they were acquired, using a 7 year study timeframe. / text

This thesis has investigated nearwork-induced transient myopia and accommodation responses in relation to refractive stability, multichromatic stimuli and orthokeratology. Five individual studies have been carried out. Initially an investigation into the temporal and dioptric aspects of nearwork-induced transient myopia was undertaken, suggesting that increased task duration does not increase the level, or slow the regression of post-task NITM, however an increase in the dioptric demand of the task does. In the second study, a longitudinal myopia progression study, these findings were related to short term myopia progression. The third investigation demonstrates the feasibility of measuring the biometric correlates of nearwork-induced transient myopia using a low coherence reflectometry device (LenStar, Haag Streit Koeniz, Switzerland). Fourthly, a comparison of the differences between static and dynamic accommodative responses, microfluctuations and nearwork-induced transient myopia produced when viewing a black/white target as oppose to a red/blue target has suggested the possibility of four accommodative responses to this multichromatic stimulus. Further investigation will be necessary to investigate if any of these response types are related to myopia progression. 2 The final study investigates the effect of two different designs of orthokeratology contact lenses (C5 and polynomial) on visual function. It appears to be the case that although the polynomial lens design has a larger refractive effect than the C5 lens it reduces both high and low contrast corrected visual acuity to a greater extent. The higher the baseline mean spherical equivalent refractive error the larger the detrimental effect.

Conventional stereoscopic displays present a pair of stereoscopic images on a single and fixed image plane. In consequence, these displays lack the capability of correctly rendering focus cues (i.e. accommodation and retinal blur) and may induce the discrepancy between accommodation and convergence. A number of visual artifacts associated with incorrect focus cues in stereoscopic displays have been reported, limiting the applicability of these displays for demanding applications and daily usage. Depth-fused multi-focal-plane display was proposed to create a fixed-viewpoint volumetric display capable of rendering correct or nearly-correct focus cues in a stereoscopic display through a small number of discretely placed focal planes. It effectively addresses the negative effects of conventional stereoscopic displays on depth perception accuracy and visual fatigue. In this dissertation, the fundamental design methods and considerations of depth-fused displays were refined and extended based on previous works and a high-resolution optical see-through multi-focal-plane head-mounted display enabled by state-of-the-art freeform optics was developed. The prototype system is capable of rendering nearly-correct focus cues for a large volume of 3D space extending into a depth range from 0 to 3 diopters at flicker-free speed. By incorporating freeform optics, the prototype not only achieves high quality imagery across a large 3D volume for the virtual display path but it also maintains better than 0.5 arcminutes visual resolution of the see-through view. The optical design, implementation and experimental validation of the display are presented and discussed in detail.

This study aims to examine how the interventions for homeless persons in the municipality of Kalmar are organized. The study is based on four half-structured qualitative interviews with both representatives from different instances and also from persons who have experience of being homeless. The theoretical bases we have used to analyze the material are organization theory, specifically the concept of bureaucracy. Our results show that homelessness is not seen as a problem in itself, since the general view is that homeless people often have a complex problem scenario where drug- and alcohol abuse and mental illness are common. It is often the latter that takes priority in the interventions and the housing question is therefore neglected. We also found that social services do not have a satisfactory structure around the organization of the work on homelessness. They do not have any specific device in Kalmar that focus on homelessness issues with the result that the existing units are forced to take care of the work of homelessness. This represents a problem as the interventions are being adapted to this area of specialization with the result that the housing issue is overlooked. Another conclusion is that there is a lack of long-term solutions in the municipality. Today the efforts are mainly aimed at placing homeless people in short-term temporary accommodation.

Many Indigenous leaders and public figures, as well as scholars of Indigenous culture and history, assert that non-Indigenous ignorance of Indigenous realities has systematically disadvantaged Indigenous peoples in Canada, weakened Canadian society, and makes it impossible to address the conditions of life for Indigenous people in Canada in a sustained or coherent way. Additionally, for many scholars silence and unawareness are deeply linked to colonialism and are implicated in the maintenance of unequal social relations. Drawing from this literature, I contend that in Canada, silence around Indigenous peoples and issues works as a spatial tactic of exclusion. I argue that unawareness is bound up in interests that work to render Indigenous peoples absent from the concerns of modern Canada, and that these interests are deeply intertwined with national and provincial identities such that silences around Indigenous peoples and issues are expressed differently in each Canadian province and territory. This thesis explores the nature of public unawareness of Indigenous realities in Québec. Using the remarkable public voice resource generated by the 2007 Reasonable Accommodation Commission in Québec, a public inquiry into Québec citizens’ opinions about the nature of Québec identity and its relationship to the integration of minorities in the province, I analyze the Commission’s mandate and geographical movements, as well as over 750 written briefs submitted to the Commission. I argue that unawareness of Indigenous realities is widespread in Québec and is unconstrained by participants’ social positions, interests, arguments, or level of engagement with the question of indigeneity in Québec. Though the Commission worked to exclude Indigenous content (and perhaps peoples) from its activities from the outset, eight Indigenous leaders submitted briefs and spoke powerfully and critically of the Commission’s exclusion. These authors point out that the question of Indigenous rights is far from settled, that the Commission’s and Quebecers’ unawareness of Indigenous realities is complicit in a long history of exclusion in Québec and in Canada, and assert that Quebecers will not be able to address their anxiety around immigration in any meaningful or coherent way until Indigenous rights are respected. In my focus on the Reasonable Accommodation Commission, I suggest the particular nature of exclusion in Québec. While exclusion of Indigenous peoples is a Canadian universal, its flavour varies. In this case, the provincial jurisdiction is important. / Thesis (Master, Geography) -- Queen's University, 2012-04-22 18:11:39.47

This practicum focuses on the issues of the overlapping boundaries between Student housing and downtown redevelopment. Can graduate students find a place in the downtown to meet their need for off-campus housing, and simultaneously help build a healthy, vibrant, downtown community; ensuring the housing facility represents a quality space for both graduate students and the local community? The following is an investigation of related issues including: Richard Florida’s notion of the Creative Class, multi-purpose development, the university as an urban catalyst, and adaptive reuse. The combination of graduate housing and the city’s downtown redevelopment will create new design typology that benefits both graduate students and downtown community. The practicum project consists of a live/work space for Winnipeg in the Waterfront area by adaptively reusing the James Ave Pumping Station building. The renovated building includes a bookstore, a coffee shop, a daycare, and an urban grocery store. However, the design focuses on the informal learning space and the quality of graduate students’ living experience through aspects such as accommodation, study space, meeting and casual spaces.
