Suspects,Lies, and Videotape: An Analysis of Authentic High-Stake Liars

This study is one of the very few, and the most extensive to date, which has examined deceptive behavior in a real-life, high-stakes setting. The behavior of 16 suspects in their police interviews has been analyzed. Clips of video footage have been selected where other sources (reliable witness statements and forensic evidence) provide evidence that the suspect lied or told the truth. Truthful and deceptive behaviors were compared. The suspects blinked less frequently and made longer pauses during deceptive clips than during truthful clips. Eye contact was maintained equally for deceptive and truthful clips. These findings negate the popular belief amongst both laypersons and professional lie detectors (such as the police) that liars behave nervously by fidgeting and avoiding eye contact. However, large individual differences were present.     

Criminal psychological profiling of serial arson crimes

The practice of criminal psychological profiling is frequently cited as being applicable to serial arson crimes. Despite this claim, there does not appear to be any empirical research that examines serial arson offence behaviors in the context of profiling. This study seeks to develop an empirical model of serial arsonist behaviors that can be systematically associated with probable offender characteristics. Analysis has produced a model of offence behaviors that identify four discrete behavior patterns, all of which share a constellation of common nondiscriminatory behaviors. The inherent behavioral themes of each of these patterns are explored with discussion of their broader implications for our understanding of serial arson and directions for future research.     

The relative electoral impact of central party co-ordination and size of party membership at constituency level

Over the past decade, clear evidence has been produced showing that effective constituency campaigning in British general elections can lead to better electoral performance. This evidence has challenged the received wisdom that only national campaigning is significant and that efforts at local level are meaningless rituals. Denver et al. have focused on the role of the national parties in strengthening local campaigns in target seats; Seyd and Whiteley, by contrast, have stressed the importance of local party membership. This article attempts to assess the relative electoral impact of national party co-ordination and constituency party membership and suggests that the impact of these two factors varies by party.     

Pricing Outputs: A Case Study in Law Enforcement

This paper discusses the advantages and limitations of economic evaluation as a measurement methodology within the Australian government's outcome and output framework including preliminary benefit–cost analysis of Australian Federal Police investigations. The results suggest that the Australian Federal Police is returning over $5 to the community for every dollar invested in fraud and drug investigations. It is concluded that benefit–cost analysis is a useful tool for comparing the price of an output to the value of an outcome. The method has limitations. Not all outcomes will admit of easy assessment and the information may be difficult to collect. However, the use of surrogate measures and extrapolation of results may overcome most of these limitations.
