Randomised controlled trials (RCTs) are acknowledged to provide the most reliable estimate of programme effectiveness, yet relatively few are undertaken in children's services. Consequently, there are few models with a demonstrated impact on child well‐being, leading to a concern not only that services may frequently be ineffective but also that some may be harmful. This article considers how this state of affairs has come into being and discusses potential remedies for improving both the knowledge base and the quality of interventions. It focuses on ‘operating systems’ that link prevention science and community engagement and so help communities, agencies and local authorities to choose effective prevention, early intervention and treatment models. Specifically, it describes an attempt in Ireland to implement a robust programme of research into children's health and development, to rigorously design new services, evaluate their impact to the highest standard (using RCTs)and integrate the results into the policy process. Based on the authors' extensive first‐hand experience of supporting the work, and the advice of international experts, the article reflects critically on the unforeseen challenges and offers lessons for others starting a similar enterprise.

Primary care in the UK has been the subject of numerous changes and reorganizations since 1990. Each innovation in organization, with the exception of fundholding, has been the subject of evaluation. However, the complexities of some innovations make the evaluation process problematic and this is further complicated by the trend towards central policy decision making being subject to local interpretation and implementation, by means of simultaneous devolution and centralization. This paper discusses the challenges and problems posed by attempting to evaluate these new organizations, particularly with regard to whether or not they can be considered to be “successful”. It draws specifically on the national evaluation of the total purchasing pilots and indicates how the findings can be applied to primary care groups.

The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

BP Chemicals Aerospace Composites has launched a JAR‐145 approved maintenance organization for aerospace composite components.

Purpose – This chapter examines how those who study issues related to radicalization and counter-radicalization have recently drawn from the experiences of former extremists to inform our understanding of complex issues in terrorism and extremism studies.

Approach – The authors synthesize the empirical research on radicalization and counter-radicalization that incorporates formers in the research designs. In doing so, the authors trace these research trends as they unfold throughout the life-course: (1) extremist precursors; (2) radicalization toward extremist violence; (3) leaving violent extremism; and (4) combating violent extremism.

Findings – While formers have informed our understanding of an array of issues related to radicalization and counter-radicalization, empirical research in this space is in its infancy and requires ongoing analyses.

Value – This chapter provides researchers, practitioners, and policymakers with an in-depth account of how formers have informed radicalization and counter-radicalization research in recent years as well as an overview of some of the key gaps in the empirical literature.

To explain how reading, rewinding a story in reverse order, and then rereading allows a reader to contextualize information, acquiring not only major themes and events but also details and other literacy characteristics of the literature selection.

A representation of sequencing structures is discussed including world-related, concept-related, inquiry-related, learning-related, and utilization-related. In addition, the instructional design aspects of backwards sequencing are discussed.

Just as a level or stud finder uses a back-and-forth approach for finding the most suitable position, so does the backwards sequential approach to reading comprehension. By slowing down and focusing on parts before the whole, students are more likely comprehend content.

The importance of prediction towards comprehension has been recognized for decades. However, using a learning design that features reading a story once, then revisiting the story structure components in backwards order, and finally reading it again, allows for precise and complete learning. This theory has research and pedagogical implications for students of all ages.

This paper replicates four highly cited, classic lab experimental studies in the provision of public goods. The studies consider the impact of marginal per capita return and group size; framing (as donating to or taking from the public good); the role of confusion in the public goods game; and the effectiveness of peer punishment. Considerable attention has focused recently on the problem of publication bias, selective reporting, and the importance of research transparency in social sciences. Replication is at the core of any scientific process and replication studies offer an opportunity to reevaluate, confirm or falsify previous findings. This paper illustrates the value of replication in experimental economics. The experiments were conducted as class projects for a PhD course in experimental economics, and follow exact instructions from the original studies and current standard protocols for lab experiments in economics. Most results show the same pattern as the original studies, but in all cases with smaller treatment effects and lower statistical significance, sometimes falling below accepted levels of significance. In addition, we document a “Texas effect,” with subjects consistently exhibiting higher levels of contributions and lower free-riding than in the original studies. This research offers new evidence on the attenuation effect in replications, well documented in other disciplines and from which experimental economics is not immune. It also opens the discussion over the influence of unobserved heterogeneity in institutional environments and subject pools that can affect lab results.
