Journal of AIDS and HIV Research Collecting whole network data for human immunodeficiency virus prevention: A review of current strategies
No full textThe study of social networks is essential to understanding the spread of infectious diseases. This study reviews strategies for collecting whole (that is, sociometric) network data for human immunodeficiency virus (HIV) prevention. Using selected criteria, peer-reviewed journal articles published from 1980 to 2012 were searched in ISI Web of Knowledge and PsychInfo databases, and social network journals. Data from articles represent 12 whole network studies; the preponderance of the remaining articles was from personal (that is, egocentric) network studies. A common approach used to devise a whole network was recruiting and linking personal networks. Other approaches included venue-based linkages and use of a population roster. Ethnography and chain referral methods were key components of a multi-method approach to successfully acquiring a whole network. Few studies adequately explicate data collection and linking methodologies. Potential ways to augment and standardize reporting for similar studies are suggested
Computational discovery of effective hepatitis C intervention strategies
No full textThis project aims to develop a comprehensive, data-driven agent-based model for Hepatitis C Elimination in people who inject drugs (PWID) (HepCEP) using the Chicago PWID population as a template and proof of concept that would enable policy makers to identify the most effective intervention strategies for elimination of hepatitis C by 2030 based on the WHO proposed reduction estimates

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
