Making Buffalo Urban Food System Networks Visible

Working with different stakeholders and local communities in Buffalo, we ( Emmanuel Frimpong Boamah ,  Zachary Korosh ,  Samina Raja ,  Yeeli Mui ,  Martha Bohm ,  Allison DeHonney ,  Rebekah Williams ,  Carol Ramos-Gerena and myself) make visible the social network infrastructure of people sustaining the urban food system in the post-industrial city of Buffalo, NY. Abstract:  This article makes visible the social network infrastructure of people sustaining the urban food system in the  post-industrial city of Buffalo, NY. It does so by probing how networks are launched and sustained over time,  who is responsible for the networks, and to what end. The authors employ a survey to collect data on social  networks among actors within the city’s food system. The findings suggest that Buffalo’s urban food system is a  constellation of close-knit networks comprised primarily of local grassroots organizations having ‘small world’  effects— that is, short chains of actors within the network l

Evaluating U.S. Smart Cities' Proposal

With Chihuangji (Herbert) Wang , Yixuan Zhao, and Li Yin , we have evaluated 78 Smart City proposals that have been submitted to U.S. Department of Transportation 2015 Smart City Challenge.  Abstract: Smart City (SC) strategies developed by local governments reflect how governments and planners envision SC and apply smart technologies, and what challenges they face and try to address. Little attention, however, has been given to investigating SC strategies or applications, especially in the U.S. context. Moreover, there is insufficient attention paid to whether SC strategies address social issues such as equity and public participatory opportunities. Based on the documentation from the U.S. Department of Transportation 2015 Smart City Challenge, we developed a framework to evaluate SC strategies on urban transportation systems using six standards: Safety, Mobility, Sustainability, Opportunity, Efficiency, and Equity. In addition, we synthesized the challenges U.S. smart cities encounte

Covid-19 Vaccine Discussion on Cyber, Relational and Physical Spaces

During the 2020 Covid-19 pandemic, lockdown and social distancing policies have greatly limited human activities in the physical space, and people relied on social media to stay connected while being physically apart. With  Andrew Crooks and Li Yin , we studied how social media affects information propagation from physical to relational and cyber spaces.    Abstract: With the advent of social media, human dynamics studied in purely physical space have been extended to that of  a cyber and relational context. However, connections and interactions between these hybrid spaces have not  been sufficiently investigated. The “space-place (Splatial)” framework proposed in recent years allows capturing  human activities in the hybrid of spaces. This study applies the Splatial framework to examine the information  propagation between cyber, relational, and physical spaces through a case study of Covid-19 vaccine debates in  New York State (NYS). Whereby the physical space represents the regiona

Detecting Spatial Clusters of Housing Abandonment in a Shrinking City

Li Yin , Robert M. Silverman and myself, we have published a article entitled "Spatial clustering of property abandonment in shrinking cities: a case study of targeted demolition in Buffalo, NY’s African American neighborhoods" in Urban Geography.  Abstract Many low-income and minority-concentrated neighborhoods have been struggling for decades with the acute problem of endemic abandonment in shrinking cities. Using high-resolution spatial– temporal data, this study attempts to extend our understanding of the influence of abandonment on future abandonment and the impact of interventions such as demolition by identifying spatial patterns of housing abandonment and demolition in Buffalo, New York when the city invested heavily in an aggressive 5-in-5 demolition plan targeting predominantly African American neighborhoods with high rates of abandonment. Our results confirmed that the clustering of abandoned properties has been consistently confined to the city’s majority African
