<p>A critical factor in transit mode share analysis is the level of accessibility to transit services. The objective of this study is to investigate the relationships between accessibility and the built environment, and the use of transit. To do so, the proportion of transit users is modeled as a function of socio-economic characteristics, transit level of service, and built environment characteristics. While accessibility to transit has been the object of previous research, accessibility <em>by</em> transit is a factor that has received only limited attention in prior transit modal share research. The case study is the city of Hamilton, and the geographic unit of analysis is the Dissemination Area. A logistic model for proportions with a spatial filter (for spatial autocorrelation) and an over-dispersion parameter is found to provide the best fit and statistical properties. The results of analysis at the meso-scale show that accessibility by transit contributes positively to usage of transit. The possibility that factors at the micro-scale may also influence use of transit, suggests the development of a methodology, based on the use of spatial filtering, to systematically select walkability audit sites. The proposed methodology is demonstrated by means of a case study of neighborhoods in Hamilton. Statistical analysis of walkability audit information shows that the proposed selection strategy can be used to better target limited resources for field-based work, and produce valuable insights into the micro-level factors that may affect transit use.</p> / Master of Arts (MA)

<p>Lack of physical activity participation is one of the greatest challenges facing health care providers and policy makers in Canada. Increases in health problems linked to inactive lifestyles, such as obesity, heart disease, and asthma, have led health promotion experts to engage Canadians to become more active. Despite these efforts, many Canadians remain inactive and at risk. Active travel (AT), defined in this study as walking for travel, is a key form of physical activity that continues to decline. This dissertation examines the decline of AT and role the individual, physical, and social environment have on AT.</p> <p>The individual environment is examined by providing evidence of how perceived barriers to walking influence the AT of population sub-groups by modeling each barrier comparing agreement versus disagreement. Results find females, senior citizens, and those with a higher body mass index identify the most barriers, while young adults, parents, those owning a driver’s license, and those owning a bus pass identify the fewest barriers.</p> <p>The physical environment is examined by providing an improved conceptualization of the built environment (BE). First, the BE-AT relationship is examined by comparing the relationship when measuring the BE using an aggregate method with a disaggregate approach of measurement. As a result, both aggregate and disaggregate BE variables are significant, but the aggregate approach hides the fact that only two of the five BE variables are significant when using the disaggregate approach. Second, the influence the modifiable areal unit problem (MAUP) has on the relationship between AT and the BE is investigated. The results find that the relationship between AT and the BE are influenced by scale zone effect of MAUP.</p> <p>The social environment is examined through the adoption of a conceptual framework from the physical activity literature that combines the social environment with individual and physical environments. A series of linear regression models evaluating the different components of the social environment find that only role models and neighborhood social cohesion influence AT, despite the fact that the social environment is significantly related to walking for exercise in the literature.</p> / Doctor of Philosophy (PhD)

The opportunity to educate obese patients on healthy lifestyle practices and address habits related to chronic disease development is present among many physician office visits, though this opportunity is often overlooked (Flocke, Stange, & Goodwin, 1998). Understanding ways to improve the medical education and enhance the counseling skills of future physicians are of practical and personal relevance to current research. By improving the ways in which physicians counsel obese patients on weight management practices, the healthcare paradigm is poised to create an indelible mark on the wellbeing of our nation. Based on the need to address patient education and counseling, the purpose of this study was to investigate the relationship between physician attitudes and health behaviors on their overall communication and communication skills. The study surveyed 38 second-year medical residents at the New York University Bellevue School of Medicine using the Weight Management Survey developed by NYU researchers. Communication and counseling skills were measured using scores from Objective Structured Clinical Exams (OSCEs) administered on the same day as the Weight Management Counseling survey. Results of the survey and the OSCEs were analyzed to investigate relationships between each survey item of three categories of questions (attitudes toward weight management counseling, attitudes toward obese patients, physician health habits) and each of two sets of OSCE scores (obesity-related communication skills and overall counseling skills). Results of the data analysis suggest significant relationships between physicians' personal health habits–specifically dietary habits–and obesity counseling–related communication skills. Results also suggest a significant relationship between physicians' attitudes toward obesity counseling-related communication skills and overall communication skills. Although an extensive body of evidence corroborates these relationships, future investigations should administer the surveys and methods used in this study in rural as well as other urban locations in order to improve variability among medical residents surveyed and assessed. These results also highlight the need to investigate more information about the learning environment of medical residents and also the working environment of physicians, in a variety of settings, in order to provide more depth to the body of literature suggesting providers' health habits improves patient health outcomes. / Ph.

The built environment can be structured to encourage or discourage social interaction and can have effects on children's cognitive, social, and emotional development as well as effects on elder's health and well-being. Knowing the profound influence of the built environment on elders (Garin, et al., 2014) and children (Bradford, 2012), the design of intergenerational spaces therefore has the potential to influence the interaction between elders and children engaged in intergenerational programming. Intergenerational care programs present opportunities for cooperation and exchange of skills, knowledge, and experience between people of different age groups (Bradford, 2012; Jarrott, 2011; Kaplan et al., 2002; Newman, 1997). Highlighting the common points and connections between architectural phenomenology and human development theories, this study presents the benefit of developmental theories being applied empirically in architectural design when creating intergenerational facilities in order to enhance the quality of intergenerational interactions. To address this goal, this study examines physical environments that can effectively and efficiently provide intergenerational services. The objectives of this study are to find out (1) whether or not the identification and adaptation of human development theories and architectural phenomenology inform the extension of normative design for intergenerational facilities and (2) in what ways do architectural conditions of an intergenerational space meet the needs of multiple age groups and facilitates interaction. The study uses grounded theory framework to develop a theory related to the influence of spatial design on the quality of intergenerational interactions. To accomplish this, a phenomenological description of different intergenerational spaces was conducted, followed by four to six hours of behavioral/observation mapping of the intergenerational space. The investigator interviewed the architect(s) to ascertain their main ideas and the purpose of designing the building, and the people (participants, educators, coordinators, and facilitators) involved with the intergenerational programs to indicate how the space influences intergenerational interaction. The result of reviewing and analyzing the collected data is a new model of design process grounded in theoretical tenets of personhood and contact theory and applicable for designing intergenerational facilities. / Ph.

It is easy to overlook the individual features that constitute a community, including types and mix of land use, lot sizes, building type, size and height, setbacks, street and sidewalk widths, parking requirements, and infrastructure, all of which are controlled and regulated by land use development codes, more commonly referred to as zoning. Zoning is the primary means communities employ to control and guide land use and development decisions affecting the physical form of these places. However, zoning is a rigid, legal framework that separates uses and prescribes standards without describing or even considering what development will or should look like. Disenchantment with conventional zoning methods combined with innovative new approaches that address current and emerging issues are now readily available to learn from and adapt. A number of these approaches focus on design and form rather than use alone. The intentions of code reform focus on the creation of better public space, pedestrian friendly streets and communities, mixing uses and reducing parking requirements, all of which can lead to increased physical activity and healthy communities. / Master of Landscape Architecture
