There is a growing interest in English-speaking jurisdictions, including Australia, North America, Canada, the United Kingdom and New Zealand, about the prevention of sexual abuse perpetrated by children against other children. The aim of this review was to identify opportunities for research, policy and practice which could enhance the prevention agenda relating to the perpetration of sexual abuse by children through conducting a Critical Interpretive Synthesis. Eleven electronic databases were searched in the period from 22 April to 23 May 2013 and included: SocINDEX, Social Services Abstracts, Applied Social Sciences Index and Abstracts, Family and Society Studies Worldwide, Project Muse, PsychINFO, Family and Society Plus, Jstor, Expanded Academic ASAP, Web of Science and Google Scholar. Key individual journals were also searched, including Child Abuse and Neglect and the Journal of Interpersonal Violence, as well as the grey literature. The search was guided by the research question: How could the prevention agenda relating to sexual abuse perpetrated by children be enhanced? The systematic literature search yielded 3323 titles, and 34 of these papers were included in the final synthesis. The authors identified five domains operating in the evidence base: characteristics, causes, communications, interventions and treatments. A synthesising construct emerged from the review: prevention-enhancing interactions. This construct referred to the potential for enhancing the prevention agenda which exists as the evidence domains interact with one another, and with the public health model of prevention. The authors consider this review to be a timely contribution to the current agenda pertaining to sexual abuse perpetrated by children. It provides researchers, policy makers and practitioners in the field with an evidence-informed conceptualisation of opportunities for enhancing prevention work. [ABSTRACT FROM AUTHOR]

Background: The value of a life is regularly monetised by government departments for informing resource allocation. Guidance documents indicate how economic evaluation should be conducted, often specifying precise values for different impacts. However, we find different values of life and health are used in analyses by departments within the same government despite commonality in desired outcomes. This creates potential inconsistencies in considering trade-offs within a broader public sector spending budget. We provide evidence to better inform the political process and to raise important issues in assessing the value of public expenditure across different sectors. Methods: Our document analysis identifies thresholds, explicitly or implicitly, as observed in government-related publications in the following public sectors: health, social care, transport, and environment. We include both demand-side and supply-side thresholds, understood as societies' and governments' willingness to pay for health gains. We look at key countries that introduced formal economic evaluation processes early on and have impacted other countries' policy development: Australia, Canada, Japan, New Zealand, the Netherlands, and the United Kingdom. We also present a framework to consider how governments allocate resources across different public services. Results: Our analysis supports that identifying and describing the Value of a Life from disparate public sector activities in a manner that facilitates comparison is theoretically meaningful. The optimal allocation of resources across sectors depends on the relative position of benefits across different attributes, weighted by the social value that society puts on them. The value of a Quality-Adjusted Life Year is generally used as a demand-side threshold by Departments of transport and environment. It exceeds those used in health, often by a large enough proportion to be a multiple thereof. Decisions made across departments are generally based on an unspecified rationing rule. Conclusions: Comparing government expenditure across different public sector departments, in terms of the value of each department outcome, is not only possible but also desirable. It is essential for an optimal resource allocation to identify the relevant social attributes and to quantify the value of these attributes for each department. [ABSTRACT FROM AUTHOR]
