Columnar‐Thin‐Film‐Assisted Visualization of Depleted Sebaceous Fingermarks on Nonporous Metals and Hard Plastics

A fingermark on a nonporous substrate can be developed by depositing a columnar thin film (CTF) on it, but the CTF technique's sensitivity for low‐quality fingermarks is unknown. The optimized CTF and traditional development of several depletion series of sebaceous‐loaded fingermarks were compared using a split‐print methodology as well as subjective and objective grading schemes, in a limited laboratory trial. CTF development was superior to development with selected traditional techniques on brass, anodized aluminum, black acrylonitrile butadiene styrene (ABS), and white nylon. On white ABS and black nylon, the CTF technique performed poorly but still as well as the best‐performing traditional development technique. The CTF technique was more sensitive on brass and anodized aluminum than, and as sensitive on the four hard plastics and stainless steel as, the best‐performing traditional technique. Thus, the CTF technique is useful to develop friction‐ridge detail from limited fingermark residue on some smooth substrates.     

Compensating the Losers: An Examination of Congressional Votes on Trade Adjustment Assistance

Globalization intensifies political conflict between citizens whose circumstances improve from foreign trade and those whose lives deteriorate as a result of trade. To pacify these rival interests, governments may assist citizens who become unemployed due to trade. When and under what conditions will legislators fund such assistance programs? The current study addresses this question by examining Congressional roll call votes in the United States during a period of rapid economic integration (1980–2004). The analysis reveals that protrade legislators who represent relatively more exporters are more likely to vote for increased spending on Trade Adjustment Assistance (TAA) programs. Exporters and their elected representatives arguably support such expenditures to broaden the protrade coalition.     

Do the experiential and deterrent effect operate differently across gender?

Deterrence research showed that successful criminal episodes tended to erode the effect of sanction risks. In particular, experience with offending—especially offending without punishment—was believed to cause individuals to lower their unrealistically high expectations of sanction risk. At the same time, other research showed that deterrence could work for some individuals such that high perceptions of sanction certainty tended to inhibit future episodes of criminal activity. One unanswered question was the extent to which these ‘experiential’ and ‘deterrent’ effects operated differently across gender. Self-reported survey information on over 2,000 adolescents was employed to examine whether the experiential and deterrent effects varied across gender. Results indicated more similarities than differences linking deterrent and experiential effects to self-reported delinquency. Future research directions are outlined.     

Participation in the Wake of Adversity: Blame Attribution and Policy-Oriented Evaluations

In this paper we investigate to what extent perceptions of economic conditions, policy-oriented evaluations, and blame attribution affected Californians’ involvement in political activities in 2010. We use a statistical methodology that allows us to study not only the behavior of the average citizen, but also the behavior of “types” of citizens with latent predispositions that incline them toward participation or abstention. The 2010 election is an excellent case study, because it was a period when citizens were still suffering the consequences of the 2008 financial crisis and many were concerned about the state’s budgetary crisis. We find that individuals who blamed one of the parties for the problems with the budget process, and who held a position on the 2010 Affordable Care Act, were often considerably more likely to participate. We also find, however, that the impact of economic evaluations, positions on the health care reform, and blame attributions was contingent on citizens’ latent participation propensities and depended on the class of political activity.     

To Behave Like a Liar: Nonverbal Cues to Deception in an Asian Sample

The detection of deception is an essential yet challenging component of investigative interviewing. Behavioural cues to deception in particular, have long been used in investigative interviewing contexts to determine decisions of suspect veracity and deceit. Nevertheless, deception research amongst non-American or European populations has yet to fully explore the effectiveness of such non-verbal observations. This study may be the first to examine truth-lie behaviours involving South-East Asian participants. In this study conducted in Singapore, 68 participants completed either a mock criminal task or a non-criminal task, before encountering an investigative interviewing scenario in which they had to lie or tell the truth to the interviewer. The results showed that liars displayed significantly more head movements and less hand/finger movements, as well as reported more feelings of guilt, than truth-tellers. Implications for investigator training and criminal investigative procedures are discussed.     

Updating,subtyping, and perceptions of the police: Implications of police contact for youths’ perceptions of procedural justice

Individuals enter police encounters with expectations about how these interactions will unfold. These expectations are often rooted in racialized personal, vicarious, and collective experiences with the police. Bayesian updating posits that the way youth perceive treatment by the police during stops and arrests combines with prior expectations and perceptions to shape current views of the law, whereas subtyping suggests this process differs by race. This study examines intra- and interracial variability in these processes using longitudinal survey data from 3,085 Black and White youth. Regardless of race, youth who indicate they were treated with disrespect during police encounters had lower perceptions of procedural justice than did those with no contact, whereas contact perceived as respectful had no significant effects. For White but not Black youth, police encounters rated as “neutral” are associated with more negative views of the police. Other forms of legal socialization are also racialized, including messages conveyed in the media and by parents. Limited evidence exists that prior views of the police moderate the effect of police encounters on procedural justice or that these conditioning effects vary by race. Findings support updating, but race differences do not neatly align with findings expected with updating or subtyping theory.     

Dating hot spot to fraud hot spot: Targeting the social characteristics of romance fraud victims in England and Wales

Research Summary

We found that romance fraud was rising year-on-year across every region in England and Wales, increasing 55% during the 3 years between October 2018 and October 2021. Fifty percent of all the romance fraud victims in the period resided in 17% of the places where romance fraud had occurred. A total of 439 locations (outward postcode areas) were identified as the “power few” in the first year of the data set. Of these 439 locations, 162 of them recurred in both of the following years, becoming chronic “hot spot” locations containing more than one in six of all reported romance fraud victims. The demography of victims in repeat locations differed considerably, but hot spots were more frequently predominantly populated by less affluent populations.

Policy Implications

We conclude that the current national one-size-fits-all fraud prevention approach may not be the most efficient or effective way to reach those victims who most require crime prevention advice. The National Fraud Intelligence Bureau, based in the City of London Police, could adopt a tailored approach to providing preventative information to local police forces based on the year-to-year patterns in crime and the associated intelligence provided by sociodemographic data sources such as Acorn.
