In a general adult population, PrEP is a high-cost intervention which will have maximum impact and be cost-effective only in countries that have high levels of HIV burden and low levels of male circumcision in the population. Hence, PrEP will likely be most effective in Southern Africa as a targeted intervention added to existing strategies to control the HIV pandemic.

In this article, we explore how cameras are used in policing in the United States. We outline the trajectory of key new media technologies, arguing that cameras and social media together generate the ambient surveillance through which graphic violence is now routinely captured and circulated. Drawing on the work of Michel Foucault, we identify and examine intersections between video footage and police subjectivity in case studies of recruit training at the Washington state Basic Law Enforcement Academy and the Seattle Police Department's body-worn camera project. We analyze these cases in relation to the major arguments for and against initiatives to increase police use of cameras, outlining what we see as techno-optimistic and techno-pessimistic positions. Drawing on the pragmatism of John Dewey, we argue for a third position that calls for field-based inquiry into the specific co-production of socio-techno subjectivities.

In this article we propose a mode of analysis that allows us to consider security as a form distinct from insecurity, in order to capture the heterogeneity of security objects, logics and forms of action. We first develop a genealogy for the anthropology of security, demarcating four main approaches: violence and state terror; military, militarization, and militarism; para-state securitization; and what we submit as 'security assemblages.' Security assemblages move away from focusing on security formations per se, and how much violence or insecurity they yield, to identifying and studying security forms of action, whether or not they are part of the nation-state. As an approach to anthropological inquiry and theory, it is oriented toward capturing how these forms of action work and what types of security they produce. We illustrate security assemblages through our fieldwork on counterterrorism in the domains of law enforcement, biomedical research and federal-state counter-extremism, in each case arriving at a diagnosis of the form of action. The set of distinctions that we propose is intended as an aid to studying empirical situations, particularly of security, and, on another level, as a proposal for an approach to anthropology today. We do not expect that the distinctions that aid us will suffice in every circumstance. Rather, we submit that this work presents a set of specific insights about contemporary US security, and an example of a new approach to anthropological problems.
