Focusing on the social environment as well as the individual should both enhance our understanding of HIV transmission and assist in the development of more effective prevention programs. Networks are an important aspect of drug injectors' social environment. We distinguish between (1) risk networks (the people among whom HIV risk behaviors occur) as(More)
Ⅲ Using a quasi-experimental design, this study examined how delivering a brief training to volunteers in church congregations impacted (a) church volunteers' persistence in delivering HIV antibody testing messages over time and (b) HIV antibody testing behavior of the church volunteers themselves. Church volunteers attended a briefing regarding delivery of(More)
A generic and scalable Reinforcement Learning scheme for Artificial Neural Networks is presented, providing a general purpose learning machine. By reference to a node threshold three features are described 1) A mechanism for Primary Reinforcement, capable of solving linearly inseparable problems 2) The learning scheme is extended to include a mechanism for(More)
