Contrast Enhancement of Bite Mark Images Using the Grayscale Mixer in ACR in Photoshop®

Enhanced images may improve bite mark edge definition, assisting forensic analysis. Current contrast enhancement involves color extraction, viewing layered images by channel. A novel technique, producing a single enhanced image using the grayscale mix panel within Adobe Camera Raw^®, has been developed and assessed here, allowing adjustments of multiple color channels simultaneously. Stage 1 measured RGB values in 72 versions of a color chart image; eight sliders in Photoshop^® were adjusted at 25% intervals, all corresponding colors affected. Stage 2 used a bite mark image, and found only red, orange, and yellow sliders had discernable effects. Stage 3 assessed modality preference between color, grayscale, and enhanced images; on average, the 22 survey participants chose the enhanced image as better defined for nine out of 10 bite marks. The study has shown potential benefits for this new technique. However, further research is needed before use in the analysis of bite marks.     

‘I'm a photographer,not a terrorist’: the use of photography to detect deception

When planning large-scale incidents or bombing campaigns, terrorists often conduct reconnaissance research to identify key targets. This may include taking photographs of potential target locations. Identifying an effective real-time method to distinguish between genuine photographers and those with more sinister intent may be beneficial for law enforcement and security agencies. Participants took photographs in a public place with a genuine intent (truth tellers) or sinister intent (liars). After taking these photographs, the participants were approached by an undercover interviewer (a mime artist) who asked them whether he could see the photographs. Later, the participants discussed their photographs in a formal interview. First, liars were less cooperative in their interaction with the undercover interviewer than truth tellers. Second, in the formal interview, liars mentioned some security features that appeared in the photographs more than truth tellers. The findings suggest that ‘using photographs to detect deception’ is a subject that could prove important to explore to benefit forensic and counter-terrorist practice.     

Developmental and offence-related characteristics of different types of adolescent sex offender: A community sample

Abstract

Offence-related and developmental characteristics were compared in subgroups of a sample (n=184) of male sex offenders aged between 10 and 21 [mean=16.07; standard deviation (SD)=2.09] referred to a specialist community facility. Important differences were observed on key developmental and offence-related variables between adolescents who targeted peers/adults and those who targeted children. These differences support the validity of the distinction between these two groups. Much smaller subgroups with mixed (i.e. peer and child) victims, internet child pornography and indecent exposure offences are also described. The sample was followed-up for a mean period of 4 years 6 months (SD=30.5 months), during which a small number re-offended sexually (n=13) and many more re-offended non-sexually (n=90). Relationships between engagement with treatment and some background and offence-related variables were identified and these are discussed.     

Exploring the role of locus of control in sex offender treatment

Abstract

This study aims to investigate the concept of Locus of Control (LoC) and its relationship to risk, personality disorder and treatment outcome in sexual offenders. The sample was taken from referrals to a community treatment service for sexual offenders in south-east London. One hundred and eighty-five men completed a measure of LoC at the time of assessment, of whom 74 entered the treatment programme and 39 completed a post-treatment LoC measure. At assessment, child molesters and non-contact offenders had a significantly more external LoC than rapists, and LoC was also significantly associated with cluster A and C personality disorder traits, as well as the presence of traits in two or more personality disorder clusters. LoC was not associated with risk measures or compliance with treatment. Once outliers were removed, a significant change was seen in post-treatment LoC scores, with most change occurring in an increasingly internal direction.     

Risk,reconviction rates and pro-offending attitudes for child molesters in a complete geographical area of London

Abstract

The study reports on all convicted child molesters in an inner city area over seven years, half of whom received a community treatment package. The average time at risk in the community was three years. There were 17 ‘failures’: subjects who were either breached for non-compliance, or reconvicted for general, violent or sexual offences. Historical, rather than cognitive variables appeared to be associated with failure. Key factors were a history of being sexually victimised and previous sexual/violent convictions.     

Two heads are better than one? How to effectively use two interviewers to elicit cues to deception

Background. We examined the effect of a second interviewer's demeanour on cues to deception. We predicted that a supportive demeanour would be the most beneficial for eliciting verbal cues to deceit, as it would encourage truth tellers, but not liars, to say more. In addition, we examined the extent to which interviewees deliberately made eye contact with the interviewers. Liars take their credibility less for granted than truth tellers, and therefore have a greater drive to be convincing. Liars are thus more likely to monitor the interviewer to determine if the interviewer appears to believe them. Method. Participants appeared before two interviewers: the first asked all the questions and the second remained silent. The second interviewer exhibited either a supportive, neutral, or a suspicious demeanour. Results. Truth tellers provided significantly more detail than liars, but only in the supportive second interviewer condition. The effect of a second interviewer's demeanour on detail was perhaps remarkable given that the interviewees hardly looked at the second interviewer (less than 10% of the time). Liars displayed more deliberate eye contact (with the first interviewer) than truth tellers did. Conclusions. A supportive second interviewer has a positive effect on interviewing. We discuss this finding in the wider contexts of investigative interviewing and interviewing to detect deception.     

Explaining restraint from filibustering in the US senate

While much has been written about the increase in filibustering over the past two decades, there has been very little discussion of the fact that, even today, opponents of legislation that could be filibustered often do not exercise this institutional right – even when doing so means the difference between defeat and passage of the measure. This study seeks to explain why legislation opposed by a cloture‐preventing minority is not always filibustered. Based on a broader look at the strategic environment facing senators, this study lays out six specific hypotheses. Analysis of data from 1947–98 provides substantial empirical support for most of these hypotheses, demonstrating that the strategic calculations behind the decision to filibuster are complex and multifaceted. In particular, this study finds that for legislation on which opponents have a clear incentive to filibuster, restraint is more likely to occur when the workload is light, when parties are not polarised, when the president favours the measure, when opponents’ cloture‐preventing margin is slim, and on minor legislation.     

The Public Legitimacy of the National Assembly for Wales

This article examines the public legitimacy of the National Assembly for Wales. Both the Assembly and the broader system of devolved government for Wales initially enjoyed very limited public support. It is shown that support for devolution in general has risen substantially, while some elements of public attitudes towards the Assembly itself now appear distinctly positive. However, it is also demonstrated that public legitimacy, defined as ‘diffuse support’ for the Assembly, remains limited. The article then examines what factors explain levels of diffuse support for the National Assembly. It is found that variation in such support is best accounted for by factors associated with ‘non-material consequentialism’: perceptions of the impact of the Assembly on the process of government. The conclusion assesses the implications of the findings for the National Assembly, as well as for the study of devolution and political institutions more generally.
