Dylan Stevenson
Dylan Stevenson’s (Prairie Band Potawatomi descent) research examines how culture informs planning strategies and influences land relationships. More specifically, he investigates how tribal epistemologies structure notions of Indigenous futurities by centering Indigenous cultural values at the forefront of environmental stewardship and cultural preservation. He is currently working on a project researching how governments (Federal, State, and Tribal) embed cultural values in Water Resources Planning strategies, drawing from ethnographic research he conducted in the joint territory of the United Keetoowah Band of Cherokee Indians and Cherokee Nation in Oklahoma. His other research interests include ecological restoration, intangible cultural heritage, and food systems planning. Previously, Dylan has worked for public and quasi-public entities dealing with the implementation and compliance of local, state, and federal legislation in California and has forthcoming work analyzing Diversity, Equity, and Inclusion (DEI) initiatives in planning programs.
Dylan earned his Ph.D. in the Department of City and Regional Planning at Cornell University. He earned his master’s degree in Planning with a concentration in Preservation and Design of the Built Environment from the University of Southern California, a bachelor’s degree in Linguistics with a minor in Native American Studies from the University of California—Davis, and an associate of arts degree in Liberal Arts from De Anza College.
When To Partner For Public Infrastructure?
Whittington, Jan. (2012). When to Partner for Public Infrastructure? Journal Of The American Planning Association, 78(3), 269 – 285.
Abstract
Problem, research strategy, and findings: Public agencies traditionally request bids and award contracts to private firms after infrastructure designs are complete (bid-build). They also increasingly partner with private firms, often by folding capital improvements into a contract to design and build (design-build). The latter involves much more than the mere transfer of design work to the private sector, such as time to completion; the merits or problems of design-build strategies can, thus, be difficult to isolate. This article presents a method for doing so. Together with the development of a theory of contracting, the comparative analysis of two very similar highway overpass projects, one design-build and the other bid-build, demonstrates how so-called transaction cost economics can clarify the details of partnership cost-effectiveness. Takeaway for practice: Transaction cost analysis disaggregates and evaluates the costs of completed projects, accounting for factors typically external to economic analysis. My approach reveals tradeoffs between variables of interest to planners, such as the pace of delivery, public participation, environmental compliance, and the transfer of risk of cost overrun to the private sector.

Understanding Climate Change Risk Perception in the USA
Grover, Himanshu; Brody, Samuel D.; Vedlitz, Arnold. (2017). Understanding Climate Change Risk Perception in the USA. International Journal Of Global Warming, 13(2), 113 – 137.
Abstract
Public perceptions of risk from climate change are an important determinant of the willingness of citizens to support climate change mitigation and adaptation policies. Although there is a growing body of research focusing on a variety of individual, cultural, and organisational factors that affect an individual's perception of risk, only a few studies have adopted a multivariate analytical approach to understand public perceptions of climate change risks. This study extends earlier interdisciplinary research initiatives and proposes a more comprehensive, integrated model for understanding climate change risk perception. Using measures of objective risk, individual climate stress, and individual capacity, we explain public perceptions of climate change risks. The analysis is based on a national representative survey of US citizens. Geographic information systems and spatial analytical techniques are used to supplement the survey data with measures of objective risk associated with the location of each respondent. Analysis of the data using multivariate regression suggests that increased objective risk and individual capacity result in significantly higher perception of risk from climate change, whereas higher individual climate stress results in lower risk perceptions.

House Price Dynamics and Bank Herding: European Empirical Evidence
Martins, Antonio Miguel; Serra, Ana Paula; Martins, Francisco Vitorino; Stevenson, Simon. (2020). House Price Dynamics and Bank Herding: European Empirical Evidence. Journal Of Real Estate Research, 42(3), 365 – 396.
Abstract
This paper examines house price dynamics, bank herding behavior, and the linkages between them. The analysis presented indicates that prior to the financial crisis, non-fundamental factors played a significant role in several European countries, including the United Kingdom, Spain, Denmark, Sweden, and Ireland. We also provide evidence indicative of herding behavior in the residential mortgage loan market. Finally, Granger causality tests show that non-fundamentally justified price dynamics contributed to the herding displayed by lenders and that this behavior was a response by banks as a group to common information on residential property assets.

To Inhabit Well: Counterhegemonic Movements and the Right to the City
Purcell, Mark. (2013). To Inhabit Well: Counterhegemonic Movements and the Right to the City. Urban Geography, 34(4), 560 – 574.
Abstract
A right to the city, understood as a conjoint claim to a right to inhabit urban space well, can be an effective starting point from which diverse urban movements can begin to build broad counterhegemonic coalitions for alternative urban futures. In this article, I argue that the right to the city supports the project of establishing relations of equivalence among members of coalitions--balancing relations of sameness/difference and interdependence/autonomy.

Understanding and Improving Arterial Roads to Support Public Health and Transportation Goals
McAndrews, Carolyn; Pollack, Keshia M.; Berrigan, David; Dannenberg, Andrew L.; Christopher, Ed J. (2017). Understanding and Improving Arterial Roads to Support Public Health and Transportation Goals. American Journal Of Public Health, 107(8), 1278 – 1282.
Abstract
Arterials are types of roads designed to carry high volumes of motorized traffic. They are an integral part of transportation systems worldwide and exposure to them is ubiquitous, especially in urban areas. Arterials provide access to diverse commercial and cultural resources, which can positively influence community health by supporting social cohesion as well as economic and cultural opportunities. They can negatively influence health via safety issues, noise, air pollution, and lack of economic development. The aims of public health and transportation partially overlap; efforts to improve arterials can meet goals of both professions. Two trends in arterial design show promise. First, transportation professionals increasingly define the performance of arterials via metrics accounting for pedestrians, cyclists, transit riders, and nearby residents in addition to motor vehicle users. Second, applying traffic engineering and design can generate safety, air quality, and livability benefits, but we need evidence to support these interventions. We describe the importance of arterials (including exposures, health behaviors, effects on equity, and resulting health outcomes) and make the case For public health collaborations with the transportation sector.

Small Increments in Diet Cost Can Improve Compliance with the Dietary Guidelines for Americans
Rose, Chelsea M.; Gupta, Shilpi; Buszkiewicz, James; Ko, Linda K.; Mou, Jin; Cook, Andrea; Moudon, Anne Vernez; Aggarwal, Anju; Drewnowski, Adam. (2020). Small Increments in Diet Cost Can Improve Compliance with the Dietary Guidelines for Americans. Social Science & Medicine, 266.
Abstract
Adherence to the Dietary Guidelines for Americans (DGA) may involve higher diet costs. This study assessed the relation between two measures of food spending and diet quality among adult participants (N = 768) in the Seattle Obesity Study (SOS III). All participants completed socio-demographic and food expenditure surveys and the Fred Hutch food frequency questionnaire. Dietary intakes were joined with local supermarket prices to estimate individual-level diet costs. Healthy Eating Index (HEI-2015) scores measured compliance with DGA. Multiple linear regressions using Generalized Estimating Equations with robust standard errors showed that lower food spending was associated with younger age, Hispanic ethnicity, and lower socioeconomic status. Even though higher HEI-2015 scores were associated with higher diet costs per 2000 kcal, much individual variability was observed. A positive curvilinear relationship was observed in adjusted models. At lower cost diets, a $100/ month increase in cost (from $150 to $250) was associated with a 20.6% increase in HEI-2015. For higher levels of diet cost (from $350 to $450) there were diminishing returns (2.8% increase in HEI2015). These findings indicate that increases in food spending at the lower end of the range have the most potential to improve diet quality.

Has Transportation Demand of Shanghai, China, Passed Its Peak Growth?
Zhao, Zhan; Zhao, Jinhua; Shen, Qing. (2013). Has Transportation Demand of Shanghai, China, Passed Its Peak Growth? Transportation Research Record, 2394, 85 – 92.
Abstract
On the basis of four comprehensive transportation surveys in Shanghai, China, this study examined the latest trends in Shanghai's travel demand; investigated their social, economic, and spatial drivers; and compared the pace of travel demand growth in three periods: 1980s to early 1990s, early 1990s to mid-2000s, and mid-2000s to the present. The demand growth was relatively slow in the first period and then sped up in the second before it returned to a slower pace in the third period. As for trip purpose, Shanghai's travel is much more diversified than previously, with an increasing share of noncommuting trips (from 28% in 1995 to 46% in 2009). Spatially, travel demand is dispersed from the central district to peripheral districts because of urban expansion and decentralization and from Puxi (west of the Huangpu River) to Pudong (east of the Huangpu River) as a result of significant economic development of the Pudong New Area. Both spatial diffusion and purpose diversification favor the convenience and flexibility of private motor vehicles. Driven by rapid motorization, vehicle travel is growing at a much faster pace than person travel. Overall, the annual growth rate for travel demand in Shanghai reached its peak in 2004 for both person trips and vehicle trips. In absolute numbers, person trip growth has peaked, but vehicle trip growth has not. In response to the growing demand, especially rapid motorization, the local government has made tremendous investments in road infrastructure and public transit, and it has attempted to manage demand through vehicle ownership control.

Fuzzy AHP Model for Prequalification of Engineering Consultants in the Iranian Public Procurement System
Nazari, Ahad; Vandadian, Shaghayegh; Abdirad, Hamid. (2017). Fuzzy AHP Model for Prequalification of Engineering Consultants in the Iranian Public Procurement System. Journal Of Management In Engineering, 33(2).
Abstract
Prequalification of engineering consultants in the Iranian public procurement system is suffering from arbitrary processes and criteria that cannot effectively shortlist the increasing number of potential bidders. This study aims to develop a prequalification model that can serve as the basis for revising the existing regulations and criteria. The authors conducted interviews among experts to localize a framework of prequalification criteria. Fuzzy analytical hierarchy process (FAHP), accompanied by a survey among industry participants, was used to determine the importance level of decision criteria. The results confirmed that the existing guidelines cannot meet the expectations of the industry due to the overemphasis on the past performance of consultants and disregarding their current capabilities. For the international audience, this study clarifies that (1)the working culture of industry participants impacts their judgments on the importance level of intangible and tangible criteria used for prequalification processes, (2)short-listing consultants for long-term and fragmented data collection in national registration or project prequalification should be avoided, and (3)researchers must test FAHP models with different fuzzy scales because the success of the widely used fuzzy extent analysis method is highly dependent on the scale of fuzzy functions and judgments of decision makers.
