Detecting Deception Via Strategic Disclosure of Evidence

Deception detection research has largely neglected an important aspect of many investigations, namely that there often exists evidence against a suspect. This study examined the potentials of timing of evidence disclosure as a deception detection tool. The main prediction was that observers (N = 116) would obtain higher accuracy rates if the evidence against the suspects (N = 58) was presented in a late rather than early stage of the interrogation. This prediction was based on the idea that late evidence disclosure would trigger lack of consistencies between the liars’ stories and the evidence; this could be used as a cue to deception. The main prediction received support. Late disclosure observers obtained an overall accuracy of 61.7%, compared to 42.9% of Early disclosure observers. Deceptive statements were identified with high accuracy (67.6%) in Late disclosure, indicating that the technique in this form is beneficial mainly for pinpointing lies.     

Digital imaging methods as an aid in dental identification of human remains

The physical comparison of known (K) and questioned (Q) evidence samples is an accepted tool in numerous forensic identification disciplines (1). A subset of this process is the use of antemortem and postmortem dental radiographs to identify unidentified human remains. This method has been generally accepted for decades (2). The outcome is performed with a considerable degree of accuracy, due in part to a finite pool of possible candidates for identification derived via the NCIC database, passenger lists, and law enforcement Missing Persons reports. This paper describes a dental identification comparison protocol that incorporated digital imaging technology in this process. The computer was used to create digital exemplars of the K and Q evidence that were spatially and quantitatively compared (3). The digital mode allowed direct metric and morphologic comparison through the aid of a digital camera, desktop computer, monitor, and printer. The well-known computer program Adobe Photoshop 5.0 (4) was used to process the digital information in two forensic cases described in this paper. It is a commercially available digital imaging editing program that is operated on laptop and desktop computers possessing sufficient chip speed and RAM (Pentium II or equivalent and at least 76MB RAM) to open the large-size files generated by high-resolution digital capture devices. This program accepts raster-based image formats (e.g. .JPG, .BMP). Photoshop is noted for its diverse imaging functions, which allow the computer monitor to be used as a comparison microscope when Q and K sample images are tiled side-by-side and/or superimposed. Two and three-dimensional Q and K evidence samples can be individually digitized and then independently resized to allow two-dimensional comparison. The investigator also has the ability to create magnified images (200% to 300%) when the original digital image has been captured at near photoquality resolution (300 dpi). The visual comparison of physical features on the computer monitor permits a large field of view and robust digital control over image quality. Photographic measurement and enhancement features of Adobe Photoshop mimics and in some circumstances surpasses the historic use of conventional photographic manipulation in forensic casework. This paper presents two cases processed via routine forensic odontology identification protocols. These protocols had minimal results due to limitations described in the case histories. The additional application of digital methods proved useful in the ultimate identification of these human remains.

How to make perpetrators in denial disclose more information about their crimes

This study examined interview techniques for eliciting admissions from perpetrators of a crime. Two techniques derived from the Strategic Use of Evidence (SUE) framework (SUE-Confrontation and SUE-Confrontation/Explain) were compared to an Early Disclosure of Evidence technique. Participants (N?=?75) performed a mock criminal task divided into three phases before being interviewed. In the SUE conditions, statement-evidence inconsistencies were obtained by strategic interviewing for Phases 1 and 2. For both SUE conditions, the interviewer confronted the suspects with these inconsistencies, emphasising that withholding information undermined their credibility. For the SUE-Confrontation/Explain condition, the suspects were asked to explain each inconsistency. To restore their credibility, the suspects in the SUE conditions were expected to become more forthcoming in Phase 3 (the phase which lacked information). The suspects in the SUE-Confrontation condition (vs. the suspects in the Early Disclosure condition) disclosed more admissions about Phase 3. As predicted, the suspects in the SUE conditions perceived the interviewer to have had comparatively more information about Phase 3. The suspects in the SUE-Confrontation/Explain condition strived to maintain their credibility either by fitting their story to the evidence or by sticking to the initial story. The study shows that the SUE technique is effective for eliciting admissions.     

Music therapy for improving mental health problems of offenders in correctional settings: systematic review and meta-analysis

Objectives

The aim of this review was to assess the effectiveness of music therapy on improving the mental health of offenders in correctional settings.

Methods

Multiple databases and journals were searched to identify randomized controlled trials and quasi-randomized controlled trials of music therapy for offenders in correctional settings.

Results

Five studies (n?=?409; predominantly male) were included in random-effects meta-analyses. Music therapy was effective for promoting offenders’ self-esteem (Hedges’ g?=?0.55, p?<?0.001) and social functioning (g?=?0.35, p?<?0.05). Effects on anxiety and depression depended on the number of sessions. For both outcomes, the studies with 20 or more sessions had larger effects than the study that had fewer than 20 sessions, and this difference was statistically significant (Q?=?11.88, df?=?1, p?<?0.001, anxiety; Q?=?9.16, df?=?1, p?=?0.002, depression). No significant effects were found on behavior management or between different music therapy approaches.

Conclusions

Music therapy may be helpful for offenders to improve mental health. Future studies should consider including offenders of both genders, using larger sample sizes, and examining long-term effects. Publication bias may be an issue for this review given the small number of studies and the small sample sizes.

     

Organized medicine and Scandinavian professional unionism: hospital policies and exit options in Denmark and Sweden

Strikes by junior hospital doctors over the issue of on-call remuneration in Denmark and Sweden in 1981 are analyzed to clarify the impact of public-sector cost-control policies on intra- and interprofessional solidarity within the Scandinavian professional peak associations. The junior doctors' grievances could find expression either through increased "voice" within the medical negotiating machinery, or by pursuing the exit option in having the medical associations quit the peak associations. The article explains why the "exit" option was selected in Denmark, while in Sweden the granting of additional voice helped persuade the medical association to withdraw its exit threat and to remain within the peak association. The two cases are interpreted as presaging a divergence in the paths being taken by the various Scandinavian welfare states.     

Training Police Investigators to Interview to Detect False Intentions

This study is the first to investigate police investigators’ adherence to, and the effectiveness of, a training program for detecting true and false intentions. Experienced police investigators (N = 53) were either trained or not trained in how to interview to discriminate between true and false intentions. All investigators interviewed mock suspects (N = 53), of which half lied and half told truth about their intentions. Both subjective and objective measures showed that the trained investigators interviewed in line with the training received. That is, a large proportion asked about the planning of the stated intentions. Noteworthy, none of untrained investigators reported to have posed such questions for strategic purposes. The trained investigators reached a higher detection accuracy level (65 %) than their untrained colleagues (55 %), however not significantly. Given that the investigators adhered to the training, this training package is a viable starting point for developing more effective training programs.     

Exploring Microfinance Clients with Disabilities: A Case Study of an Ecuadorian Microbank

Using a unique sample from an Ecuadorian microfinance institution that has focused on increasing its outreach to disabled clients, we present a comparative analysis of the characteristics of disabled versus non-disabled clients. The study shows that disabled clients are more often male, are less likely to be living with a partner, have fewer children, and are older compared to their non-disabled counterparts. Moreover, we observe differences in repayment statistics between clients with and without disabilities, as well as differences within the disability sample. Our findings illustrate the importance of adapting microloans to the special needs of persons with disabilities.     

Geographical redistribution with disproportional representation: a politico-economic model of Norwegian road projects

Politicians bias public policies to favor particular election districts. According to the traditional common pool model, districts facing low tax shares should receive relatively large government projects. We suggest a swing-voter model where the number of voters on the ideological cut point, lack of party identification and number of district representatives per voter determine project sizes. We analyze the allocation of state road investments in Norway from 1973–1997 exploiting unique data on characteristics of voters, legislative representation and tax prices in 19 election districts. Geographical representation to parliament is biased, mostly due to an ancient constitution. Shares of swing voters and legislative over-representation lead to higher levels of road investments, while high levels of party identification reduce investments.
