Organizational Ecology of Hyperlocal Groups: How Does Category Fuzziness Relate to Participation in an Event-Based Social Network?
Social categories serve as key anchors for organizations and groups, helping to establish their identities and positions within conceptual spaces such as market and cultural niches. Researchers have examined the social categorization of both online communities and offline organizations through tags, folksonomies, and news outlets. While these studies have provided valuable insights into the success of online communities and formal organizations, …
Mapping linguistic landscapes and displacement: Urban-scale analysis of internally displaced people in Kyiv using street view imagery and computer vision
Internally displaced people (IDPs) who fled conflict zones in Donetsk and Luhansk beginning in 2013 relocated to other cities in Ukraine. Their Russian-language preference can be quantitatively and qualitatively observed and measured in the urban textual environment, or linguistic landscape (LL) of Kyiv, the bilingual Ukrainian capital. This study examines the LL at a city-wide scale, leveraging Google Street View imagery with deep learning text …
Predicting the success of local gatherings: A comparison of organizer- and participant-side success in Meetup
This study examines the dynamics of local gatherings facilitated by Event-Based Social Networking (EBSN) platforms, an increasingly prominent mode of social interaction in urban settings. Although EBSN platforms are widely used to organize local events, little research has investigated the factors that determine their success across diverse urban environments or how socio-spatial contexts shape participation. To address this gap, we analyze a lar…
Countering Violent Extremism in Trinidad and Tobago: An Evaluation
This paper investigates the history of violent extremism and evaluates the status of countering violent extremism (CVE) policies in Trinidad and Tobago, focusing on government, international partners, and NGO programming. Through more than twenty extended interviews with grassroots organizations, politicians, and members of the security administration alongside an exploration of budgetary and personnel data, we seek to illuminate major challenges…
Achieving situational awareness of drug cartels with geolocated social media
Crowdsourcing Street View Imagery: A Comparison of Mapillary and OpenStreetCam
Over the last decade, Volunteered Geographic Information (VGI) has emerged as a viable source of information on cities. During this time, the nature of VGI has been evolving, with new types and sources of data continually being added. In light of this trend, this paper explores one such type of VGI data: Volunteered Street View Imagery (VSVI). Two VSVI sources, Mapillary and OpenStreetCam, were extracted and analyzed to study road coverage and co…
Responses to mass shooting events: The interplay between the media and the public
Research Summary Public mass shootings tend to capture the public's attention and receive substantial coverage in both traditional media and online social networks (OSNs) and have become a salient topic in them. Motivated by this, the overarching objective of this paper is to advance our understanding of how the public responds to mass shooting events in such media outlets. Specifically, it aims to examine whether distinct information seeking pat…
Need for an Integrated Deprived Area "Slum" Mapping System (Ideamaps) in Low- and Middle-Income Countries (LMICs)
Ninety percent of the people added to the planet over the next 30 years will live in African and Asian cities, and a large portion of these populations will reside in deprived neighborhoods defined by slum conditions, informal settlement, or inadequate housing. The four current approaches to neighborhood deprivation mapping are largely siloed, and each fall short of producing accurate, timely, and comparable maps that reflect local contexts. The …
A Critical Review of High and Very High-Resolution Remote Sensing Approaches for Detecting and Mapping Slums: Trends, Challenges and Emerging Opportunities
Slums are a global urban challenge, with less developed countries being particularly impacted. To adequately detect and map them, data is needed on their location, spatial extent and evolution. High- and very high-resolution remote sensing imagery has emerged as an important source of data in this regard. The purpose of this paper is to critically review studies that have used such data to detect and map slums. Our analysis shows that while such …
The study of slums as social and physical constructs: Challenges and Emerging Research Opportunities
Over 1 billion people currently live in slums, with the number of slum dwellers only expected to grow in the coming decades. The vast majority of slums are located in and around urban centres in the less economically developed countries, which are also experiencing greater rates of urbanization compared with more developed countries. This rapid rate of urbanization is cause for significant concern given that many of these countries often lack the…
