Mémoire numérisé par la Division de la gestion de documents et des archives de l'Université de Montréal. / Le développement de l’identité régionale dans la région de la capitale nationale fut l’objet de problématiques diverses. Ce développement identitaire eut même des répercussions au niveau de l’aménagement de son territoire. Depuis plus d’un siècle, plusieurs événements survenus sur la scène politique, économique, sociale et culturelle ont eu un impact sur l’aménagement de la région. En 1946, le gouvernement canadien fit appel à Jacques Gréber, un architecte aménagiste d’origine française, afin de réaliser un plan d’aménagement pour le territoire de la capitale nationale. Ses propositions d’aménagement suggéraient une relocalisation des équipements industriels et ferroviaires en périphérie du centre-ville ainsi qu’un reverdissement et une mise en valeur des berges et cours d’eau de la région. De plus, ces recommandations visaient parallèlement à développer une capitale où l’aménagement reflèterait une identité pancanadienne. Le projet de Gréber ne fut cependant pas réalisé intégralement. Afin de comprendre le développement de la région, nous ferrons appel à certains éléments de la géographie structurale. Cette approche théorique permettra de révéler la présence d’une structure sous-jacente au territoire, ayant influencé le développement urbain. La configuration de cette structure fut, elle aussi, influencée par les changements sociaux survenus au sein de la population. Ces derniers eurent un impact sur la perception qu’avait la population sur son environnement et par conséquent sur la réalisation d’aménagements sur le territoire. Finalement, une comparaison entre les volontés d’aménagements de Gréber et la structure sous-jacente permettra d’expliquer les résultats de la réalisation du Plan Gréber et d’autres projets plus récents. / The development of regional identity in the National Capital Region has been at the centre of a variety of issues, it even had repercussions on regional urban planning. Since the late 19th century, many events that occurred in the political, economic, social and cultural spheres have had major impacts on the urban development of the region. In the middle of the 20th century, the Canadian government asked Jacques Gréber, a French planner and architect, to propose a plan for the National Capital Region. The plan suggested that all industrial and railroad equipment should be relocated outside the downtown area and that the esthetical aspect of the shores and the rivers be improved. Furthermore, these recommendations had a parallel objective of promoting a Canadian identity through the urban planning. The current layout of the region reveals that Greber’s plan was not fully implemented. To understand the development of the region, we will refer to certain elements of the structural geography theory. This theoretical approach will reveal a subjacent structure that influenced the urban development. The configuration of this structure was also influenced by social change occurring in the population. These changes had an impact on the population’s perception of its environment and consequently on planning and implementation. Finally, a comparison of Gréber’s development plans and the subjacent structure revealed by the morphogenetic path of urban development, provided by the structural geography theory, will allow for the explanation of the results of the implementation of Greber’s plan and other more recent planning projects.

The thesis examines how the social construction of African women in development discourse transformed from the 1970s to the 2000s, focusing in particular on the Canadian International Development Agency (CIDA). From the 1970s to the 1990s representations of African women were based on women’s economic potential. The mainstreaming of gender in the 1990s resulted in women being represented as agents of change. This approach gave women an opportunity to play roles in decision-making but led to policies that failed to challenge the established institutions. The emphasis on women as agents of change opened doors to some African women but with implications for the women’s movement. Only some middle-class women appear to benefit but their gains have been marginal in comparison to the gender inequalities that persist. The thesis uses secondary sources and interviews with development practitioners in Ottawa to understand the representation of African women as agents of change.

During the 2009 H1N1 pandemic, the City of Ottawa implemented a program to disseminate vaccination clinic information using the microblogging tool Twitter. The purpose of this thesis is to examine and evaluate whether this program constitutes a communicative model. The challenge for crisis communicators has been to convince a confused and skeptical public to be vaccinated against the virus. Drawing on Aristotle’s Rhetoric and Rousseau’s The Social Contract, the theoretical framework of this thesis feeds from Heidegger’s (1977) views on technology, new media, Web 2.0 technologies, Eid’s (2008) Crisis Decision-Making Model for Media Rational Responsibility, Rowan, Botan, Krepes, Samoilenko and Farnsworth’s (2008) CAUSE model, Crozier’s (1967) Theory of Bureaucratic Dysfunction and New Public Management. The thesis employs a case study approach and utilizes a qualitative research design to analyze the Twitter messages and internal City of Ottawa documents, and to conduct in-depth interviews with employees. Findings reveal and explain that the City of Ottawa’s program constitutes a flawed communicative model. A recommended communicative model is put forth in order to improve the areas of planning, human resources and message design. This model contributes to the emerging field of social media, and is intended to help health crisis decision-makers communicate their messages effectively.

This work comprises two main parts. The first part outlines our efforts to expand on the recent work of Gütlich et.al. by synthesizing Co(II) based spin crossover systems within a dendritic framework. We wanted to investigate the possibility of synthesizing different first generation, triazole containing dendrimers using “click” type reactions and their coordination ability with Co(II) ions. To this end we have had limited success mainly due to the numerous challenges in synthesizing a pure dendrimer product. The second part details our efforts in the synthesis of a mononuclear Co(II) based single molecule magnet. This comes as an extension to recent reports by Chang and Long where they have successfully obtained mononuclear Fe(II) single molecule magnets by inducing structural distortions within the complexes to amplify the spin-orbit coupling. We postulated that the use of Co(II) in conjunction with a bulky ligand framework would lead to desirable magnetic properties. We chose the known bis(imino)pyridine ligand scaffold due to its rich chemistry and its interesting and unexpected coordination behaviour, as we have seen in previous research efforts by our lab. To this end we were successful in isolating and characterizing 4 compounds, and we have carried out detailed magnetic measurements on the two most magnetically interesting species.

This thesis investigates the phenomenon of for-to complements in several dialects, focusing primarily on Appalachian English, though Belfast English and Ottawa Valley English are also examined. Following Chomsky's Government and Binding theory, we develop an analysis of for-to that predicts the distribution of for-to complements based on the requirements of Case, and the varieties of licit movement of features allowed by each dialect. To do this, we propose a Revised Case Filter which requires functional categories bearing Case features to discharge Case. We also show that the features of functional categories can move either by head movement (allowing movement of to into for) or by feature transmission (allowing for to move into to). / Each of these mechanisms generates a specific range of well-formed for-to complements; the distribution of these complements can be predicted by the ways in which the dialects allow features to move. Appalachian English and Ottawa Valley English allow head movement of features only, while Belfast English allows features to move via head movement and feature transmission. Thus for-to complements are more wide-spread in Belfast English than in the other for-to dialects. Standard English, which does not allow features to move unless they are accompanied by lexical material, does not exhibit for-to complements at all.
