How central are clients in sexual networks created by commercial sex?

Sex workers are traditionally considered important vectors of transmission of sexually transmitted infections (STI). The role of clients is commonly overlooked, partially due to the lack of evidence on clients' position in the sexual network created by commercial sex. Contrasting the diffusion importance of sex workers and their clients in the map of their sexual encounters in two Web-mediated communities, we find that from diffusion perspective, clients are as important as sex workers. Their diffusion importance is closely linked to the geography of the sexual encounters: as a result of different movement patterns, travelling clients shorten network distances between distant network neighborhoods and thus facilitate contagion among them more than sex workers, and find themselves more often in the core of the network by which they could contribute to the persistence of STIs in the community. These findings position clients into the set of the key actors and highlight the role of human mobility in the transmission of STIs in commercial sexual networks.

Geo-social journalism: reorienting the study of small commercial newspapers in a digital environment

This paper begins by problematizing the use of “community” to define and theorize small commercial media outlets that have geography as their primary characteristic—particularly hyper local and small traditional newspapers connected to larger media organizations in digital space. We then extend the concept of “geo-social news” to outline “geo-social journalism” as a specific form of news work currently grouped under the “community media” umbrella. Geo-social is a concept for exploring how small commercial newspapers change as media technologies evolve. It offers a framework for understanding how these news outlets and audiences connect via the notion of “sense of place”. It can also be used as a lens for theorizing their role in social flows and movements and as nodes in the global media network. The practice of “geo-social journalism”, meanwhile, has two dimensions. Firstly, journalists must engage with the land (environment/agriculture/industry), populations, histories and cultures of the places they report news. Secondly, it involves connections and understandings of the shifting constellations of global and national systems, issues and relationships of the digital era. Finally, this paper argues that by its very nature, “geo-social journalism” eschews theoretical universalizing and instead demands fine-grained analyses of the specific dynamic of each “geo-social” publication, its setting and the practices which shape it and it in turn shapes.

Civic Discipline: Geography in America, 1860-1890

Civic Discipline argues that the story of the origins of American geography is a distinctly "New York story." Wealthy businessmen began America's first geographical society - the American Geographical Society - in 1851, inspired by what geographical knowledge of the globe could offer an expanding American commercial Empire at home and abroad. AGS meetings were spectacularly popular among the public and press. At them, geography was cast as a science in the service of the public and civic good. Meanwhile though, AGS men's spatial and financial "missions" became closely linked. They helped improve derelict spaces in New York City and weighed in on controversial scientific questions of the day in the Arctic, yet the geographical knowledge they advanced - such as in the American West and in Central Africa - also created enormous personal wealth. Civic Discipline shows that it was not just that historical events shaped geography, but rather, that geography shaped historical events.
