"Despite global progress in understanding the epidemiology of the human immunodeficiency virus (HIV), knowledge about the epidemic in the Middle East and North Africa (MENA) remains limited and subject to much controversy. In the more than 25 years since the discovery of HIV, no scientific study has provided a comprehensive, data-driven synthesis of the spread of HIV/AIDS (acquired immunodeficiency syndrome) in the region. Consequently, the effectiveness of policies, programs, and resources intended to address the spread of HIV/AIDS has been compromised. This report aims to fill the knowledge gap by providing the first-ever comprehensive scientific assessment and data-driven epidemiological synthesis of HIV's spread in MENA. It is based on a literature review and analysis of thousands of largely unrecognized publications, reports, and data sources extracted from scientific literature or collected from sources at the local, national, and regional levels. The resulting collection of data provides a solid foundation on which efforts to stem the spread of HIV/AIDS can be based. 'Characterizing the HIV/AIDS Epidemic in the Middle East and North Africa' will be of particular interest to policy makers, researchers, development practitioners, and specialists in public health and epidemiology."
The articles in this volume illustrate how development is propelled by the bidirectional relations that occur between the person and all levels of the context. The authors argue that adolescent life is embedded in a complicated developmental system involving multiple features of the individual (e.g., biology, emotions, personality, and cognition) and the multiple levels of his or her social ecology (e.g., peers, family, school, the workplace, and the public policy and legal systems that structure and impact behavioural opportunities for and the actions of adolescents). These articles have important implications for the design of interventions aimed at adolescent problem behaviours.
