The forensic analysis of thermal transfer printing

Thermal transfer printing refers to printing processes that utilize heat to produce an image by either physical or chemical means or by a combination of both. As the technology has improved and the supplies have become less expensive, the use of thermal printing in the personal and business markets has increased significantly. Specifically, dye diffusion thermal transfer and thermal mass transfer have become predominant in the production of counterfeit credit cards, drivers' licenses, and other types of documents produced on plastic media. Chemical analysis by means of thin layer chromatography (TLC) has proven to be useful in characterizing various types of inks (e.g., writing and inkjet inks). In this study, the authors examined 81 different samples that included a total of 54 printer samples (43 photographic prints on paper and eleven plastic card samples) and 27 printer ribbons. A new TLC method was developed and tested utilizing a solvent system (80% n-hexane, 3% methyl ethyl ketone, and 17% ethyl acetate) that is capable of producing excellent resolution.     

Object-oriented Bayesian networks for paternity cases with allelic dependencies

This study extends the current use of Bayesian networks by incorporating the effects of allelic dependencies in paternity calculations. The use of object-oriented networks greatly simplify the process of building and interpreting forensic identification models, allowing researchers to solve new, more complex problems. We explore two paternity examples: the most common scenario where DNA evidence is available from the alleged father, the mother and the child; a more complex case where DNA is not available from the alleged father, but is available from the alleged father’s brother. Object-oriented networks are built, using HUGIN, for each example which incorporate the effects of allelic dependence caused by evolutionary relatedness.

Safeguarding Access to Justice in the Age of the Online Court

In 2016 Her Majesty's Courts and Tribunals Service embarked on a significant modernisation programme with a view to developing online courts. In pursuit of this ambition the Courts and Tribunals (Online Procedure) Bill seeks to introduce new procedural rules to govern the online jurisdiction, giving the Lord Chancellor and an Online Procedure Rule Committee the power to mandate which proceedings will be conducted online and what assistance will be provided to users. In this study we analyse survey data and case decisions to highlight the importance of channel plurality and digital support in light of the shift to online courts. Our findings identify the groups most at risk of digital exclusion, and the expectations the judiciary sets in relation to internet access, capability, and the design of online systems. We conclude by detailing what our findings mean for safeguarding access to justice in the digital age.     

Administrative Growth and Grant Payouts in Nonprofit Foundations: Fulfilling the Public Good amid Professionalization?

The Tax Reform Act of 1969 remains the core governing policy for the U.S. foundation sector, primarily for its qualifying distributions mandate, which ensures a baseline spending of foundation assets toward charitable purposes. However, implementation of this policy required additional foundation administrative resources and contributed to significant professionalization of the foundation sector. This article focuses on the payout requirement's potential paradox of accountability, as administrative expenses can be counted toward fulfilling foundations’ qualifying distributions. Using a 14‐year panel of grantmaking foundations, the analysis seeks to understand whether professionalization, measured by operating and administrative expenses, contributes to or crowds out grantmaking. Findings indicate that professionalization of the foundation sector has a small yet practically and statistically significant positive association with foundation grantmaking. From a policy perspective, the current structure of the qualifying distributions mandate does not appear to lead to a crowding out of grant allocations as administrative expenses grow.     

Assessing callous–unemotional traits in adolescent offenders: Validation of the Inventory of Callous–Unemotional Traits

The presence of callous–unemotional (CU) traits designates an important subgroup of antisocial youth. To improve upon existing measures, the Inventory of Callous–Unemotional Traits (ICU) was developed to provide an efficient, reliable, and valid assessment of CU traits in samples of youth. The current study tests the factor structure and correlates of the ICU scale in a sample (n = 248) of juvenile offenders (188 boys, 60 girls) between the ages of 12 and 20 (M = 15.47, SD = 1.37). Confirmatory factor analyses are consistent with the presence of three independent factors (i.e., Uncaring, Callousness, and Unemotional) that relate to a higher-order callous–unemotional dimension. Also, CU traits overall showed associations with aggression, delinquency, and both psychophysiological and self-report indices of emotional reactivity. There were some important differences across the three facets of the ICU in their associations with these key external criteria.
