Walkability indices are currently used for a wide range of research and commercial applications. Few studies have examined the relationship between walkability indices and measured pedestrian volume or walking rates, nor explored moderators of pedestrian volume such as weather. With 14 years of traffic study data from the City of Ottawa, a spatial auto-regressive (SAR) multi-level model (MLM) was used to understand the proportion of variance in walking explained by the commercial Walk Score® index and selected weather variables. Modeling revealed that a significant proportion of pedestrian volume at a given location in Ottawa, including its spatial lag, was explained by the corresponding Walk Score® value and its spatial lag (51.45%). Furthermore, weather expressed as a combination of ‘felt’ temperature, presence or absence of precipitation, and percent cloud cover, accounted for 2.79% of the variance in walking. These findings indicate that walkability indices may provide value as cost-effective engineering and urban planning tools.

This thesis examines the impact of urban water infrastructure on the Ottawa River through an exploration of the City of Ottawa's historical development from the early modern period to the present. The primary aim is to explain how the Ottawa River came to be removed or ignored from the City of Ottawa's urban development strategy. The thesis focuses on the periods of 1910-1920 (early modernity) and 1999-2012 (present). The theories applied are risk, risk management, normal accident theory and the politics of infrastructure. The data and information for this thesis were primarily retrieved from the City of Ottawa website as well as from the archives of the City of Ottawa. The thesis identifies several factors explaining why the Ottawa River has been mistreated over time, as well as the challenges involved in reforming present-day practices and infrastructure. Several recommendations to fix the situation are advanced.

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.
