In providing a comprehensive investigation of alcohol, cigarette, and marijuana initiation among adolescents, the overarching goals of the research were to build upon extant findings, address important gaps found in the literature, and contribute to the prevention science knowledge base. A four-fold purpose founded the study: 1) provide a systematic review of the soft drug initiation literature; 2) test a modified version of Kandel's (2002) drug sequencing hypothesis; 3) determine if predictors of soft drug initiation differ in kind or saliency by biological age and drug type; and 4) examine age- and drug- specific determinants of the timing at which soft drug initiation occurs. Supplemental attention also was directed at evaluating the utility of Petraitis et al.'s (1995) distal-proximal mediation hypothesis. Through the quantitative component of the research, nine hypotheses were tested. Cross-sectional data were derived from a rural sample of 6th, 9th, and 12th grade students who completed the 2004 Primary Prevention Awareness, Attitude, and Use Survey (PPAAUS). All of the hypotheses obtained some degree of support; more support was yielded for the specific risk factor hypothesis than the common factor model, and convincing evidence was obtained for Kandel's drug sequencing hypothesis and Petraitis et al.'s distal-proximal mediation hypothesis. The findings also supported the bulk of the directional hypotheses and several of the direct and indirect effects propositions put forth in social learning theory, the social development model, and the theory of planned behavior. In contrast, the results called into question some of the direct effects articulated in Hirschi's original statement of social control and underscored some possible limits of the social development model. In an effort to gauge the validity of the findings, a dual cross-validation scheme was employed. The systematic review cross-validation involved comparing the quantitative findings for two major hypotheses to those yielded from 36 primary studies examined in the systematic review. Through a further quantitative cross-validation, the findings for the major and supplemental hypotheses were compared to those derived from a sample of 6th, 9th and 12th grade students who completed the 2001 PPAAUS. On balance, a relatively strong degree of convergence was obtained. This confluence served to bolster the reliability and validity of the results. Policy and programmatic implications also were indicated.
This book provides a detailed and practical exploration of criminal recidivism and social reintegration in Jamaica. It uses various methods to seek the authentic voices of inmates, ex-prisoners, deported migrants and practitioners, drawing on an original study to examine factors that might help ex-prisoners more successfully transition from a prison environment to life within the community. Leslie also raises important questions about the Jamaican state’s capacity to meet the needs of inmates, particularly as a large number of its citizens are subject to forced repatriation to their homeland by overseas jurisdictions due to their offending. Recidivism in the Caribbean provides a unique insight into institutional and community life in a post-colonial society, whilst linking practices theories of offender management. It will particularly appeal to criminologists and sociologists interested in tertiary crime prevention but also those interested in correctional policy and practice, punishment and deviance.
Healthcare decision makers in search of reliable information that compares health interventions increasingly turn to systematic reviews for the best summary of the evidence. Systematic reviews identify, select, assess, and synthesize the findings of similar but separate studies, and can help clarify what is known and not known about the potential benefits and harms of drugs, devices, and other healthcare services. Systematic reviews can be helpful for clinicians who want to integrate research findings into their daily practices, for patients to make well-informed choices about their own care, for professional medical societies and other organizations that develop clinical practice guidelines. Too often systematic reviews are of uncertain or poor quality. There are no universally accepted standards for developing systematic reviews leading to variability in how conflicts of interest and biases are handled, how evidence is appraised, and the overall scientific rigor of the process. In Finding What Works in Health Care the Institute of Medicine (IOM) recommends 21 standards for developing high-quality systematic reviews of comparative effectiveness research. The standards address the entire systematic review process from the initial steps of formulating the topic and building the review team to producing a detailed final report that synthesizes what the evidence shows and where knowledge gaps remain. Finding What Works in Health Care also proposes a framework for improving the quality of the science underpinning systematic reviews. This book will serve as a vital resource for both sponsors and producers of systematic reviews of comparative effectiveness research.
Children are already learning at birth, and they develop and learn at a rapid pace in their early years. This provides a critical foundation for lifelong progress, and the adults who provide for the care and the education of young children bear a great responsibility for their health, development, and learning. Despite the fact that they share the same objective - to nurture young children and secure their future success - the various practitioners who contribute to the care and the education of children from birth through age 8 are not acknowledged as a workforce unified by the common knowledge and competencies needed to do their jobs well. Transforming the Workforce for Children Birth Through Age 8 explores the science of child development, particularly looking at implications for the professionals who work with children. This report examines the current capacities and practices of the workforce, the settings in which they work, the policies and infrastructure that set qualifications and provide professional learning, and the government agencies and other funders who support and oversee these systems. This book then makes recommendations to improve the quality of professional practice and the practice environment for care and education professionals. These detailed recommendations create a blueprint for action that builds on a unifying foundation of child development and early learning, shared knowledge and competencies for care and education professionals, and principles for effective professional learning. Young children thrive and learn best when they have secure, positive relationships with adults who are knowledgeable about how to support their development and learning and are responsive to their individual progress. Transforming the Workforce for Children Birth Through Age 8 offers guidance on system changes to improve the quality of professional practice, specific actions to improve professional learning systems and workforce development, and research to continue to build the knowledge base in ways that will directly advance and inform future actions. The recommendations of this book provide an opportunity to improve the quality of the care and the education that children receive, and ultimately improve outcomes for children.

Such diverse thinkers as Lao-Tze, Confucius, and U.S. Defense Secretary Donald Rumsfeld have all pointed out that we need to be able to tell the difference between real and assumed knowledge. The systematic review is a scientific tool that can help with this difficult task. It can help, for example, with appraising, summarising, and communicating the results and implications of otherwise unmanageable quantities of data. This book, written by two highly-respected social scientists, provides an overview of systematic literature review methods: Outlining the rationale and methods of systematic reviews; Giving worked examples from social science and other fields; Applying the practice to all social science disciplines; It requires no previous knowledge, but takes the reader through the process stage by stage; Drawing on examples from such diverse fields as psychology, criminology, education, transport, social welfare, public health, and housing and urban policy, among others. Including detailed sections on assessing the quality of both quantitative, and qualitative research; searching for evidence in the social sciences; meta-analytic and other methods of evidence synthesis; publication bias; heterogeneity; and approaches to dissemination.
