Neighbourhood influence in criminology can be conceptualised both as pertaining to the influence of characteristics of a neighbourhood on its inhabitants, and to the mutual influence of characteristics of adjacent neighbourhoods on each other. The first conceptualisation asks for multilevel analysis, the second one for one of several spatial dependency (spatial autocorrelation) methods. Various models in both traditions are discussed and illustrated with data on victimisation and on burglary.

Abstract  In interpreting the product moment correlation coefficient we can take advantage of the fact that functions of it exist which admit interpretation as probabilities of error in certain situations.

Abstract  This paper reviews indeterminacy problems for the factor analysis model and their consequences for the interpretation of the results. Two types of indeterminacy are discerned: indeterminacy of the parameters in the model (the number of factors, the specific variances and the factorloadings) and the indeterminacy of the factors, given the parameters in the model. It is argued that parameter indeterminacy is partly to be overcome, provided that a strong underlying theory for the subject matter under research is present. Factor indeterminacy remains a major stumbling‐block for the interpretation of results. The Guttman criterion is advocated as a measure of factor indeterminacy.

Objectives: The goal of this article is to examine whether or not the results of the Queensland Community Engagement Trial (QCET)—a randomized controlled trial that tested the impact of procedural justice policing on citizen attitudes toward police—were affected by different types of nonresponse bias. Method: We use two methods (Cochrane and Elffers methods) to explore nonresponse bias: First, we assess the impact of the low response rate by examining the effects of nonresponse group differences between the experimental and control conditions and pooled variance under different scenarios. Second, we assess the degree to which item response rates are influenced by the control and experimental conditions. Results: Our analysis of the QCET data suggests that our substantive findings are not influenced by the low response rate in the trial. The results are robust even under extreme conditions, and statistical significance of the results would only be compromised in cases where the pooled variance was much larger for the nonresponse group and the difference between experimental and control conditions was greatly diminished. We also find that there were no biases in the item response rates across the experimental and control conditions. Conclusion: RCTs that involve field survey responses—like QCET—are potentially compromised by low response rates and how item response rates might be influenced by the control or experimental conditions. Our results show that the QCET results were not sensitive to the overall low response rate across the experimental and control conditions and the item response rates were not significantly different across the experimental and control groups. Overall, our analysis suggests that the results of QCET are robust and any biases in the survey responses do not significantly influence the main experimental findings.

Research and theorizing on criminal decision making has not kept pace with recent developments in other fields of human decision making. Whereas criminal decision making theory is still largely dominated by cognitive approaches such as rational choice-based models, psychologists, behavioral economists and neuroscientists have found affect (i.e., emotions, moods) and visceral factors such as sexual arousal and drug craving, to play a fundamental role in human decision processes.This book examines alternative approaches to incorporating affect into criminal decision making and testing its influe

Cohen and Felson's (Cohen and Felson American Sociological Review 44(4):588–608, 1979) routine activity theory posits that for a crime to occur three necessary elements must converge in time and space: motivated offenders, suitable targets, and the absence of capable guardianship. Capable guardians can serve as a key actor in the crime event model; one who can disrupt, either directly or indirectly, the interaction between a motivated offender and a suitable target. This article critically reviews the literature on guardianship for crime prevention. Our specific focus is two-fold: (1) to review the way guardianship has been operationalized and measured, and (2) to review experimental and quasi-experimental evaluations and field tests of guardianship. Research on routine activities has had an uneven focus resulting in the neglect of the guardianship component (Reynald Crime Prevention and Community Safety 11(1):1–20, 2009; Sampson et al. Security Journal 23(1):37–51, 2010; Tewksbury and Mustaine Criminal Justice and Behavior 30(3):302–327, 2003; Wilcox et al. Criminology 45(4):771–803 2007). Evaluations of guardianship-related interventions demonstrate support for the theoretical construct; however, high-quality field tests of guardianship are wholly lacking. Implications for theory and research are discussed.
