Stylometry and forensic science: A literature review.

The article focuses on a careful description of literature on stylometry and on its potential use in forensic science. The state of the art of stylometry is summarized to illustrate the history and the scientific foundation of this discipline. However, the study conducted reveals that there are still some key unresolved aspects that require a response from the academic world.

Anticipatory Violence and Health Among Black Adults in the United States.

This study analyzes the relationship between anticipatory community and police violence and health outcomes including mental and physical well-being, sleep problems, and functional disability. Using data from a nationally representative survey of 3015 self-identified Black and African American adults in the USA collected in 2023, findings from a series of regression analyses reveal that anticipating community violence is linked to poorer self-rated health and increased sleep problems. Anticipatory police violence is associated with poorer physical health and sleep disturbances.

The feasibility of the adult age estimation 3D-CBCT method on ancient human remains.

The age estimation of skeletal remains still represents a central issue not only for the reconstruction of the so-called "biological profile," but mostly for the palaeodemographic investigation. This research aims at verifying the feasibility of the adult age estimation method developed on living people by Pinchi et al. (2015 and 2018), for estimating the age at the death of 37 subjects from ancient populations found in two different Italian necropolis of archaeological interest (Mont'e Prama and Florence, X-IX century B.

Fast and Facile Synthesis of Cobalt-Doped ZIF-8 and FeO/MCC/Cobalt-Doped ZIF-8 for the Photodegradation of Organic Dyes under Visible Light.

Co-doped ZIF-8 as a water-stable visible light photocatalyst was prepared by using a one-pot, fast, cost-effective, and environmentally friendly method. The band structure of ZIF-8 was tuned through the incorporation of different percentages of cobalt to attain an optimal band gap ( ) that enables the activation of ZIF-8 under visible light and minimizes the recombination of photogenerated charge carriers. A magnetic composite of Co-doped ZIF-8 was also synthesized to facilitate catalyst recycling and reusability through the application of an external magnetic field.

Predicting the replicability of social and behavioural science claims in COVID-19 preprints.

Replications are important for assessing the reliability of published findings. However, they are costly, and it is infeasible to replicate everything. Accurate, fast, lower-cost alternatives such as eliciting predictions could accelerate assessment for rapid policy implementation in a crisis and help guide a more efficient allocation of scarce replication resources.

Searching national DNA databases with complex DNA profiles: An empirical study using probabilistic genotyping.

In most National DNA databases (NDNADB), only single source DNA profiles, and sometimes two-person DNA mixtures, can be searched provided a minimum number of loci (or alleles) is available. DNA profiles that do not meet these criteria (about 14 % of the traces analyzed in Western Switzerland) can be compared locally with candidates upon request from police services, used for one-off search, or remain unused. With the advent of probabilistic genotyping (PG), such complex DNA profiles can be compared to those stored in NDNADB based on likelihood ratios (LRs).

Exploring racial disparities in sex trafficking special docket court programs.

Purpose: The United States criminal legal system has a long-standing and well-documented history of perpetuating racial disparities in health and well-being through inequitable policing, sentencing, and incarceration practices. In the last decade, the criminal legal system has re-considered their response to women arrested for solicitation via sex trafficking specialty courts.

Methods: The current study leverages publicly available data from one large Midwestern county to explore the presence of racial disparities within women's referral to, election to participate in, and success within one specialty court program for women in the sex trade.

Stranger Danger: Analyzing Offender Behaviors Based on Victim Approach Tactics in Sexual Homicide.

Victims of sexual homicide may be deceived by perpetrators who use a friendly approach to gain access to them, making it difficult for the victim to assess the danger posed by the stranger. When investigating sexual homicides committed by strangers, investigators often lack direct information, including how the perpetrator gained access to the victim. To identify potential predictors of the approach method used in sexual homicides, this study analyzed the preferences and behaviors of sexual murderers who target strangers based on their approach method.

Hyperspectral Raman imaging with multivariate curve resolution-alternating least square (MCR-ALS) analysis for xylazine-containing drug mixtures.

Xylazine, increasingly implicated in illicit opioid overdose deaths, poses a significant public health threat due to its synergistic effects with fentanyl and resistance to naloxone reversal. Despite its rising prevalence, xylazine is not classified as a controlled substance, leading to its exclusion from routine forensic screening. This study introduces a novel analytical method combining Raman hyperspectral imaging with Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) to detect xylazine in drug mixtures containing common excipients such as acetaminophen, dipyrone, and mannitol.

Validation and cross-sample consistency of Chinese Five-Factor Narcissism Inventory (FFNI) in community and offender samples.

Three-factor models of narcissism (Agentic, Neurotic, and Antagonistic Narcissism) have gained widespread recognition in the field. The Five-Factor Narcissism Inventory (FFNI) stands out as the most comprehensive and only tool to date that assesses all three narcissism domains. However, its validation in Chinese culture and forensic contexts remains largely unexplored.

Impact of illustrated backgrounds on the automatic assessment of fingermark quality.

In the fingermark detection field, background illustrations may negatively impact the visibility of the marks in presence. They can indeed locally reduce the contrast or mask ridge details. When conducting a research project, the choice for plain or illustrated substrates is mostly driven by the research objectives as well as the development level of the investigated technique (e.

Sickle cell trait in non-firearm arrest-related deaths of Black persons.

The role of sickle cell trait (SCT) in sudden exertional death is well-recognized in sports and military training. However, it is not yet studied for non-firearm arrest-related death (NF-ARD). With extensive multi-pronged searches, a large database (n = 1389) of NF-ARDs was established.

Driver or passenger? Use of a Bayesian network for the evaluation of DNA results in a fatal car accident.

This article presents a case where the issue was to determine who was the driver and who was the passenger at the time of a fatal car accident involving two persons, one of whom died in the accident. The presence of the two persons in the car was not contested, only the mechanisms that led to the deposition of the DNA (i.e.

"… give me a lawyer, dawg": recognizing for advice and support.

(1) Youth are particularly vulnerable to making suboptimal legal decisions due to added challenges in comprehension, as well as their ongoing neurological development. (2) This fact is especially problematic in our which frequently expects defendants to determine the outcome of their own cases (by accepting or rejecting plea offers). (3) To better ensure that guilty pleas entered by youthful defendants are indeed knowing, intelligent, and voluntary, legal counsel should be mandatory during any and all juvenile criminal proceedings.

Automated comparison and evaluation of striated cutting plier toolmarks on metal wires.

Toolmarks examination validity and subjectivity have come under scrutiny. This research focuses on the case of cutting plier marks. This paper presents an automatic comparison method and assesses its performance.

Essentialism and the criminal legal system.

Objective: Existing literature has yet to conceptualize and consolidate research on psychological essentialism and its relation to the criminal legal system, particularly in terms of explaining how individuals with justice involvement have been and could be differentially impacted across contexts. This article explores essentialism in the criminal legal system, including its potential consequences for inequity.

Method: We review research on essentialism as a psychological construct, its common applications to different social categorizations, and its trickle-down effects within the criminal legal system.

Levels and Changes in Defensive Firearm Use by US Crime Victims, 1987‒2021.

To examine levels and temporal changes in the frequency of defensive gun use by US crime victims. We computed national-level counts of criminal incidents involving firearm defense during 3 periods: 1993 to 2005, 2007 to 2015, and 2016 to 2021. We also considered earlier national estimates for 1987 to 1990.

Subtleties in Bayesian decision-theoretic analysis for forensic findings: Notes on recent discussion of the role of validation study data in rational decision making.

This technical note extends a recent discussion in this journal of the role of validation study data in rational decision making. One argument that has been made in this context, using elements of Bayesian decision theory, is that further aggregation of validation study data into error rates involves a loss of information that compromises rational inference and decision making and should therefore be discouraged. This technical note seeks to explain that this argument can be developed at different levels of detail, depending on the definition of the propositions of interest, the forensic findings to be evaluated (and hence the form of the likelihood ratio), and the characterization of the relative desirability of decision consequences.

Factors Associated With Recurrent Pediatric Firearm Injury : A 10-Year Retrospective Cohort Analysis.

Background: Firearm injuries are the leading cause of death among children aged 0 to 17 years in the United States.

Objective: To examine the factors associated with recurrent firearm injury among children who presented with acute (index) nonfatal firearm injury in the St. Louis region.

Dual Systems Imbalance as a Mediator of the Relationship Between Exposure to Violence and Violent Offending Risk: Delineating Direct Victimization and Witnessed Violence.

Exposure to violence is a robust risk factor associated with violent offending. Furthermore, exposure to violence can lead to dysfunctional cognitive development, and this may underpin the relationship between exposure to violence and violent offending risk. However, there is a dearth of research that has examined the independent effects of direct victimization and witnessed violence in this regard, particularly as it pertains to dual systems imbalance as a cognitive mediator of either or both forms of exposure to violence.

An evaluation of youth mental health first aid training with law enforcement officers.

Youth Mental Health First Aid (YMHFA) training has been adopted across the United States to teach adults how to identify and respond to youth mental health challenges and crises. Evaluations of YMHFA have yet to be undertaken with law enforcement populations, although agencies and officers are participating in the training. The present study implemented and evaluated YMHFA with law enforcement officers ( = 446) across a southeastern state.
