Binding Morality and Perceived Harm as Sources of Moral Regulation Law Support Among Political and Religious Conservatives

Conservatives—both political and religious—are more likely than liberals to support laws regulating traditional or religious morality. The current study applies a moral psychological framework to argue that the association between conservatism and moral regulation law support can be explained in part by binding morality, or a moral orientation that privileges group needs above individual needs and includes concerns about absolutism, collectivism, and purity. Binding morality may directly promote support for moral regulation laws, which enforce traditional rules, discourage deviance, and require adherence to customs regarding bodily and spiritual purity. Binding morality may also indirectly promote support for moral regulation laws by motivating perceptions that “immoral” behaviors are harmful to innocent victims. I test these hypotheses using three analytic samples drawn from the General Social Survey (N = 3669, 7120, 369). Results show that, as expected, binding morality (especially purity) mediates the effects of political and religious conservatism on laws regulating pornography, marijuana, abortion, and euthanasia. Additional analyses exploring views about pornography show that binding morality (especially collectivism) is associated with perceptions of immorality as harmful, which in turn is associated with support for regulation.     

Capturing high-resolution digital images for use in forensic document examination

In the past, pattern disciplines within forensic science have periodically faced criticism due to their subjective and qualitative nature and the perceived absence of research evaluating and supporting the foundations of their practices. Recently, however, forensic scientists and researchers in the field of pattern evidence analysis have developed and published approaches that are more quantitative, objective, and data driven. This effort includes automation, algorithms, and measurement sciences, with the end goal of enabling conclusions to be informed by quantitative models. Before employing these tools, forensic evidence must be digitized in a way that adequately balances high-quality detail and content capture with minimal background noise imparted by the selected technique. While the current work describes the process of optimizing a method to digitize physical documentary evidence for use in semi-automated trash mark examinations, it could be applied to assist other disciplines where the digitization of physical items of evidence is prevalent. For trash mark examinations specifically, it was found that high-resolution photography provided optimal digital versions of evidentiary items when compared to high-resolution scanning.     

The power of presentation: How attire,cosmetics, and posture impact the source credibility of women expert witnesses

Gender stereotypes may negatively affect perceptions of women professionals' credibility, including forensic experts. This study investigated the impact of behavior-based and appearance-based factors on women expert witness's credibility. Jury-eligible adults were shown one of 16 conditions depicting a woman expert which varied based on combinations of three primary independent variables: (1) attire, (2) cosmetic use, and (3) posture. Expert attractiveness and participants' sexist attitudes served as covariates. Results revealed that women experts were seen as marginally more credible when wearing a skirt suit with a closed posture stance than when wearing a pant suit with a closed posture. Secondary analyses indicated expert attractiveness and participant sexist attitudes accounted for the most variability in credibility scores. Credibility of women expert witnesses may be impacted by irrelevant peripheral cues. Findings can inform discussions aimed at mitigating extraneous factors that inadvertently undermine the reception of women expert witness testimony.     

The random presence of glass and paint on the clothing and footwear of members of the general population: A US baseline survey at various seasons

This study assists the interpretation of glass and paint evidence by filling an existing gap in the background occurrence that reflects the socioeconomic and demographic circumstances in the United States. The collection was performed in a college US city (Morgantown, West Virginia) to determine the effect of the type of clothing worn at different seasons on the presence of glass and paint. Tape lifts and sole scrapings (1038) were collected from 210 participants and up to six clothing and footwear areas per individual. Glass fragments were analyzed via polarized light microscopy (PLM), refractive index (RI), micro-X-Ray fluorescence (μXRF), and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), while paint specimens were examined by light microscopy and infrared spectroscopy (μFTIR). Higher occurrences of glass and paint were found in the winter season. The winter collection yielded 10 glass fragments and 68 paint particles, whereas the summer collection resulted in one glass fragment and 23 paint particles. The percentage of individuals with traces varied between seasons; 7% of individuals in the winter and 0.9% in the summer had glass, whereas 36% of individuals in the winter and 19% in the summer bore paint. Lastly, when considering the overall garment and footwear areas, glass was detected in 1.4% of the winter set, compared to 0.2% in the summer collection; paint was found in 9.2% of the winter collection, whereas only 4.2% was found in the summer set. There were no instances where both glass and paint were detected on the clothing and footwear of the same individual.     

Detection and confirmation of fentanyls in high clay-content soil by electron ionization gas chromatography-mass spectrometry

Detection of illicit drugs in the environment, particularly in soils, often suggests the present or past location of a clandestine production center for these substances. Thus, development of efficient methods for the analysis and detection of these chemicals is of paramount importance in the field of chemical forensics. In this work, a method involving the extraction and retrospective confirmation of fentanyl, acetylfentanyl, thiofentanyl, and acetylthiofentanyl using trichloroethoxycarbonylation chemistry in a high clay-content soil is presented. The soil was spiked separately with each fentanyl at two concentrations (1 and 10 μg/g) and their extraction accomplished using ethyl acetate and aqueous NH₄OH (pH ~ 11.4) with extraction recoveries ranging from ~56% to 82% for the high-concentration (10 μg/g) samples while ranging from ~68% to 83% for the low-concentration (1 μg/g) samples. After their extraction, residues containing each fentanyl were reacted with 2,2,2-trichloroethoxycarbonyl chloride (Troc-Cl) to generate two unique and predictable products from each opioid that can be used to retrospectively confirm their presence and identity using EI-GC-MS. The method's limit of detection (MDL/LOD) for Troc-norfentanyl and Troc-noracetylfentanyl were estimated to be 29.4 and 31.8 ng/mL in the organic extracts. In addition, the method's limit of quantitation for Troc-norfentanyl and Troc-noracetylfentanyl were determined to be 88.2 and 95.5 ng/mL, respectively. Collectively, the results presented herein strengthen the use of chloroformate chemistry as an additional chemical tool to confirm the presence of these highly toxic and lethal substances in the environment.
