The concept of spatial justice has been widely employed in the recent literature that attempts to deal with concepts and practices of justice from a geographical perspective. However, the concept of spatial justice needs to be recast. Spatial justice could be the most radical offspring of law’s ‘spatial turn’. Spatial justice is arguably the most promising platform on which to redefine, not o...

Recommender systems in location based social networks mainly take advantage of social and geographical influence in making personalized Points-of-interest (POI) recommendations. The social influence is obtained from social network friends or similar users based on matching visit history whilst the geographical influence is obtained from the geographical footprints users leave when they check-in...

The article describes a number of operational and methodological contributions in the search for geographically localized knowledge spillovers. The unique focus is on the role of individual inventors, and to examine, at this fundamental level of innovative activity, the impact of geographic distance, time, and political boundaries on transfers of knowledge. The analyses exploit patent citations...

Pervasive social systems often take advantage of geographical information to provide real-time information to users based on their location. However, due to privacy concerns, many social media users do not share their exact geographical coordinates. In this paper, we describe our technique that predicts locations of posts that are not associated with explicit coordinates, a process called geolo...

There is considerable debate about the effects of today’s family structures on support arrangements for older people. Using representative data from The Netherlands, the study reported in this paper investigates which sociodemographic characteristics of adult children and their elderly parents, and which motivations of the adult children, correlate with children giving practical and social supp...

Typically, the success of a collaboration technology depends on its adoption by all participants in the collaboration. But as organizations become more distributed (Castells, 1996), the challenge increases to achieve uniform adoption across geographic distance, and across organizational boundaries. In an earlier study, Mark and Poltrock (2001) discovered that the rapid and widespread adoption o...

The Boston Marathon bombing event presents a rare opportunity to study how a massive disruptive event triggers emotional contagion. In this work, we use over 180 million geocoded tweets over an entire month to study how Twitter users expressed shared fear, comfort and community identity, over time and across different cities following the bombings. We quantify the level of shared fear by using ...

social network theory, we examine how the structure of relations among organizational populations affects differences in rates of foundings across geographic locales. We hypothesize that symbiotic and commensalistic interpopulation relations function as channels of information about entrepreneurial opportunities and that differing access to such information influences the founding rate. Empiric...

Supporting security-oriented, inter-disciplinary research: crossing the social, clinical and geospatial domains. How many people have had a chronic disease for longer than 5-years in Scotland? How has this impacted upon their choices of employment? Are there any geographical clusters in Scotland where a high-incidence of patients with such long-term illness can be found? How does the life expec...
