Social Networks, HIV/AIDS and Risk Perceptions

Understanding the determinants of individuals’ perceptions of their risk of becoming infected with HIV and their perceptions of acceptable strategies of prevention is an essential step towards curtailing the spread of this disease. We focus in this paper on learning and decision-making about AIDS in the context of high uncertainty about the disease and appropriate behavioral responses, and we argue that social interaction is an important determinant of risk perceptions and the acceptability of behavioral change. Using longitudinal survey data from rural Kenya and Malawi, we test this hypothesis. We investigate whether social interactions—and especially the extent to which social network partners perceive themselves to be at risk –exert causal influences on respondents’ risk perceptions and on one approach to prevention, spousal communication about the threat of AIDS to the couple and their children. The study explicitly allows for the possibility that important characteristics, such as unobserved preferences or community characteristics, determine not only the outcomes of interest but also the size and composition of networks. The most important empirical result is that social networks have significant and substantial effects on risk perception and the adoption of new behaviors even after controlling for unobserved factors.health, AIDS, information, social networks, Africa

Relationships between Pitch-Matching and Grade Level, Gender, Ethnicity, and Classroom Teachers’ Use of Music in Grades K-3,

The purpose of this study was to examine relationships between pitch-matching and grade level, sex, ethnicity, and classroom teachers’ use of music among K-3 students (N = 289) taught by the same general music teacher. Portions of the data from a pitch-matching exercise that functioned as the music teacher’s roll-taking procedure during the 2005-06 school year were treated as pre- and posttests. There were no significant pretest differences between ethnic groups (Hispanic, White, Other). There were significant pretest differences among classes taught by different classroom teachers, as well as the female students scoring significantly higher than males. Covariance analysis (pretest as covariate) revealed significant improvement by girls over boys on the posttest. There were no significant pretest differences among grade levels, suggesting a lack of carryover of pitch-matching skills from previous years, despite significant improvement (pre-post) for every grade level during the year under study. The boys performed poorly relative to girls in higher grades, though the interaction was not significant. Finally, the study revealed relationships between classroom teachers’ reported use of music and student gain scores (pre-post) in pitch-matching

The Changing Landscape of Scholarly Publishing: Will Radiation Research Survive?

As a society published journal, Radiation Research has been a successful and enduring project of the Radiation Research Society (RRS). In 59 years of publication, the journal has produced 732 issues and 10,712 articles. As a nonprofit organization, RRS, like most societies, has used revenues from subscriptions to support, in part, the life of the organization (meetings, conferences and grants to new scholars). The model for scientific publishing, however, continues to evolve. Radiation Research has weathered the rise of electronic publishing, consolidation in the commercial publishing industry, the aggregation of library subscriptions and library subscription cuts. Recent years have seen dramatic changes in how scholarly publishing is financed and new funder and institution policies will accelerate these changes. The growth of open access to journal articles reflects the information habits of readers and facilitates the dissemination of new knowledge. The Radiation Research Society, however, will need to account for and adapt to changes in the publishing market if it intends to support the communication of peer reviewed scholarship in the future

Getting off obesity island: how informationists can enhance clinical decision support

Clinical decision support (CDS) will play a key role in improving the health of patients; informationists can support the development of CDS systems by indexing rule libraries and mapping the system logic. This work can help rule developers make more informed choices and understand how rules are related conceptually and operationally. With a map, rules can be written to bridge isolated concepts (islands) and rules that are no longer needed can be weeded. Here we explore the added value that informationists bring to projects by reporting on the role of informationists working on a pediatric CDS

Mapping the rules: conceptual and logical relationships in a system for pediatric clinical decision support

The Child Health Improvement through Computer Automation (CHICA) system uses evidence-based guidelines and information collected in the clinic and stored in an electronic medical record (EMR) to inform physician and patient decision making. CHICA helps physicians to identify and select relevant screenings and also provides personalized, just-in-time information for patients. This system relies on a database of Medical Logic Modules (MLMS) written in the Arden Rules syntax. These MLMs store observations (StorObs) during the clinical encounter which trigger potential screenings and preventive health interventions for discussion with the patient or for follow up at the next visit. This poster shows how informationists worked with the CHICA team to describe the MLMs using standard vocabularies, including Medical Subject Headings (MeSH) and Logical Observation Identifiers Names and Codes (LOINC). After assigning keywords to the database of MLMs, the informationists used visualization tools to generate maps. These maps show how rules are related by logic (shared StorObs) and by concept (shared vocabulary). The CHICA team will use these maps to identify gaps in the clinical decision support database and (if needed) to develop rules which bridge related but currently isolated concepts.NIH 1R01LM010923-0

The Social and the Sexual: Networks in Contemporary Demographic Research

The analysis of networks has become an important theme in contemporary demographic research in both developed and developing countries, including investigations of the determinants of fertility behaviors, the interaction between social network and social structures and population policies, the role of intergenerational networks in aging societies, and the relevance for sexual networks for the spread of HIV AIDS. This paper reviews the current research on networks across several domains in demographic research, and it discusses some of the specific challenges of network-based approaches with respect to data collection, analytic approaches and methodologies, interpretation of results, and micro-to-macro aggregation by drawing on research conducted as part of the Kenyan Diffusion and Ideational Change Project (KDICP), the Malawi Longitudinal Study of Families and Health (MLSFH) and the Likoma Network Study (LNS)

Gender Differentials in Consistent Condom Use among Young People in Zambia

The aim of this paper is to determine socio-economic and demographic factors that influence gender differentials in consistent use of condoms among young people in Zambia. Data for this paper were collected from a household questionnaire that was administered to sexually active youth (N=3554) between the ages of 15-24 during the 2013 Demographic Health survey. Cross tabulation and chi-square results revealed a relationship between age, gender, place of location, socio-economic background, employment status, level of education media exposure, alcohol consumption and perceived risk of contracting HIV with the consistent use of condoms. For females, regression analyses revealed that wealth status, work status, educational level and drinking alcohol were positively associated with reporting consistent use of condoms. For males, age, work status, educational level, perceived risk of contracting HIV and drinking alcohol are associated with increased likelihood of reporting consistent condom use within the last 6 months.Key Words: Gender Differentials, Condom use, Youth, Zambi

A Memorial for William V. Sliter

William V. (Bill) Sliter, an internationally known micropaleontologist and research geologist for the U.S. Geological Survey, passed away suddenly, October, 1997, while talking to a colleague in his office. In his honor, B. Huber, T. Bralower, and M. Leckie organized a keynote symposium ‘‘Paleoecological and Geochemical Signatures of Cretaceous Anoxic Events’’ at the 1998 annual meeting of the Geological Society of America in Toronto, Canada. This theme issue of the Journal of Foraminiferal Research contains the published papers from the symposium and is dedicated to his memory
