The Empirical Status of Social Learning Theory: A Meta‐Analysis

Social learning theory has remained one of the core criminological paradigms over the last four decades. Although a large body of scholarship has emerged testing various propositions specified by the theory, the empirical status of the theory in its entirety is still unknown. Accordingly, in the present study, we subject this body of empirical literature to a meta‐analysis to assess its empirical status. Results reveal considerable variation in the magnitude and stability of effect sizes for variables specified by social learning theory across different methodological specifications. In particular, relationships of crime/deviance to measures of differential association and definitions (or antisocial attitudes) are quite strong, yet those for differential reinforcement and modeling/imitation are modest at best. Furthermore, effect sizes for differential association, definitions, and differential reinforcement all differed significantly according to variations in model specification and research designs across studies. The implications for the continued vitality of social learning in criminology are discussed.     

The forensic investigation of vehicle–pedestrian collisions: A review

Rapid urbanisation, a steady increase in the number of vehicles, speeding, negligence in road safety, and other factors have led to the inevitable worldwide growth of road traffic accidents involving pedestrians. According to the ‘Global Status Report on Road Safety’ released by the World Health Organization, road traffic collisions are one of the leading causes of death for people of all ages, with approximately 1.35 million road fatality deaths occurring globally each year. Figures from the report also highlight that a large part of road deaths involves pedestrians as the most vulnerable road users. Therefore, forensic examination of vehicle–pedestrian collisions has become increasingly important in the detection, investigation and reduction of road casualties and permanent development of this discipline is urgently needed. Thus, this article aims to review the capability and effectiveness of forensic examination in tackling road fatalities and explores the most important aspects of this discipline, such as nature of a vehicle–pedestrian collision, common issues resolved by this type of examination and typical physical evidence used in the reconstruction of vehicle–pedestrian collisions. Moreover, the paper outlines the latest advances and approaches in the field.

The security of network systems — A review

Organisations in both business and government face a considerable risk from inadequately secured information systems. In recognition of these risks, Directorate-General XIII (Telecommunications, Information Industries and Innovation) of the Commission of the European Communities commissioned a series of projects to examine security issues in the use of information technology. The results of one of these studies, concentrating on the security of network systems, is reviewed below.It was an objective of the study that its results should be seen as definitive, authoritative and applicable across the European Community as a whole. In order to meet this objective, the study, led by Coopers & Lybrand, drew upon the skills and experience of 44 organisations in seven European countries, including:

• •⊎ Coopers and Lybrand practices in France, Germany, Italy, the Netherlands and the United Kingdom;
• •⊎ Admiral Management Services Ltd;
• •⊎ The Commission of the European Communities;
• •⊎ 17 vendors of IT products and services in five European countries;
• •⊎ 20 major users of network systems in seven European countries.

In particular, the study benefited from detailed case studies in each of the 20 large and sophisticated users of network systems and from assessments of 27 security products from twelve IT vendors.     

A review of the CDM literature: from fine-tuning to critical scrutiny?

As negotiations on the post-2012 climate regime are now taking off, it is time to look back and assess the experiences of the clean development mechanism (CDM) to this date. The CDM has been subject to extensive discussion in academic literature during the last few years, and this article reviews that literature in order to sum up its main themes. A common assessment is that the current structure of the CDM leads to a focus on cheap emissions reductions at the expense of sustainable development benefits for the host countries. Recently, the questionable additionality of many CDM projects has become a central issue. The article further argues that whereas a substantial body of work exists on the CDM, this work is mainly preoccupied with a ‘fine-tuning’ of the mechanism. As the CDM now becomes increasingly institutionalized, scholars should also take a step back and study the CDM in a more theoretically oriented way.

A New Ethical World of British MPs?

Following a series of financial scandals in the early 1990s, the House of Commons implemented new ethics rules and regulatory procedures, including a Code of Conduct, a ban on paid advocacy, a Parliamentary Commissioner for Standards and a Select Committee on Standards and Privileges. In the absence of hard data about parliamentary integrity and the prevalence or otherwise of unethical parliamentary conduct, this paper explores the possible effects of the new rules and procedures on MPs' attitudes by comparing data from the 2005 British Representation Study with research conducted in the late 1980s. The evidence suggests that there has been some attitudinal change at the aggregate level, although it remains unclear how much of this change can be attributed directly to the Nolan reforms.     

Uses of Meta‐Analysis in Criminal Justice Research: A Quantitative Review

Meta‐analysis has been adopted in many scientific fields for synthesizing large bodies of research, for evidence‐based development of practical policies, and for empirical resolution of difficult questions. It provides a rigorous, objective, and quantitative strategy to make effective use of an existing body of research, even when the results seem inconsistent and inconclusive. This paper reviews usage of meta‐analysis in research on criminal justice‐related issues and problems over the past three decades, identifying 176 studies published between 1976 and 2006 using meta‐analysis methods on criminal justice topics. Characteristics of these 176 studies are coded and analyzed to identify trends in the use of meta‐analysis by criminal justice researchers, as well as to summarize distinctive variations in how it has been used. A comparison of criminal justice with meta‐analysis usage in other social and applied science fields suggests some hesitation in adopting the methodology.
