The AFSP Standard - a lesson for law enforcement agencies

Compliance with the AFSP (Association of Forensic Science Providers) Standard [1] which concerns the formulation of an evaluative opinion requires consideration of the defence case. This can be problematic for forensic scientists working with or for law enforcement agencies. Among the aims of law enforcement agencies is to secure a conviction while in many jurisdictions the forensic scientist owes an overriding duty to the Court. This casework report demonstrates that early consideration of the defence case by a forensic scientist complying with the AFSP Standard may help rather than hinder the prosecution. The dichotomy as to a conflict of interest for the scientist between supporting the police/prosecutors and being scientifically objective is shown to be a false dichotomy. Compliance with the Standard ensures that science is a better servant of justice.     

Judicial Narratives of Ideal and Deviant Victims in Judges’ Capital Sentencing Decisions

Although the Victim’s Rights Movement has led to advances for victims of crime, the use of victim impact evidence in criminal trials remains controversial due to the suspicion that such evidence enhances punitive attitudes and arbitrariness in capital sentencing outcomes. Despite a growing body of literature in this area, it remains unclear if some victims are viewed more favorably than others, particularly from the perspective of judges. The current study examines the construction of victims by judges in capital cases and how this portrayal impacts sentencing outcomes in Delaware, which vests the final capital sentencing authority in judges rather than juries. In examining this gap in the literature, we consider if judges make distinctions between ideal and deviant victims, if these distinctions are associated with victim and offender characteristics, and if the construction of victims impacts offender sentencing. Findings from this study lend support to the idea that judges describe some victims as more “worthy” than others, that victims described in ideal ways are more likely to be white and female, and that “ideal victims” are more likely to result in death sentences.     

Right-Wing Authoritarianism and Social Dominance Orientation Predict Different Moral Signatures

Moral Foundations Theory posits five distinct foundations of morality: Harm/Care, Fairness/Reciprocity, In-group/Loyalty, Authority/Respect, and Purity/Sanctity. In combination, this should yield between four-to-six moral signatures—distinct combinations or patterns of support for these aspects of morality. We extend previous research by examining the replicability of these moral signatures in a New Zealand-based national sample (n = 3,635). Latent Profile Analysis identified four distinct moral signatures: Individuators, Moderates, Neutrals, and High Moralists. We integrate these moral signatures within the Dual Process Model (DPM) framework and show that Social Dominance Orientation predicts membership in the Neutral moral signature (moderate/lukewarm support for multiple moral foundations); whereas Right-Wing Authoritarianism predicts membership in the High Moralist signature (undifferentiated high support across moral foundations). These findings were observed controlling for Big-Six personality and various demographics. Thus, the authoritarian and dominance-based motives identified by the DPM independently predict categorical differences in the signatures people use to judge morality.     

Evaluation of canine training aids containment for homemade explosive and components by headspace analysis and canine testing

While canines are most commonly trained to detect traditional explosives, such as nitroaromatics and smokeless powders, homemade explosives (HMEs), such as fuel–oxidizer mixtures, are arguably a greater threat. As such, it is imperative that canines are sufficiently trained in the detection of such HMEs. The training aid delivery device (TADD) is a primary containment device that has been used to house HMEs and HME components for canine detection training purposes. This research assesses the odor release from HME components, ammonium nitrate (AN), urea nitrate (UN), and potassium chlorate (PC), housed in TADDs. Canine odor recognition tests (ORTs) were used with analytical data to determine the detectability of TADDs containing AN, UN, or PC. Headspace analysis by gas chromatography/mass spectrometry (GC/MS) with solid-phase microextraction (SPME) or online cryotrapping were used to measure ammonia or chlorine, as well as other unwanted odorants, emanating from bulk AN, UN, and PC in TADDs over 28 weeks. The analytical data showed variation in the amount of ammonia and chlorine over time, with ammonia from AN and UN decreasing slowly over time and the abundance of chlorine from PC TADDs dependent on the frequency of exposure to ambient air. Even with these variations in odor abundance, canines previously trained to detect bulk explosive HME components were able to detect all three targets in glass and plastic TADDs for at least 18 months after loading. Detection proficiency ranged from 64% to 100% and was not found to be dependent on either age of material.     

Different Threats,Different Militaries:Explaining Organizational Practices in Authoritarian Armies

Why do some states generate competent, professional military organizations, while others fail to do so even when they have the required economic, demographic, and technological endowments? Variation in states’ military organizational practices—their core policies related to promotion patterns, training regimens, command arrangements, and information management—holds the key. This article develops a typology of such practices and explains why and how they vary in response to the internal and external threats facing particular regimes. The article then subjects this argument to a carefully designed plausibility probe comparing the threat environments and military organizational practices of two states whose differences are both intuitively and theoretically puzzling: North and South Vietnam during the period 1954–1975. The initial evidence provides support for the theory and casts doubt on existing explanations of military organizational behavior focused on external threats, democracy, or the degree of political intervention in the military. The findings have important implications for foreign policy, as well as for future research on authoritarianism, civil-military relations, and military effectiveness.     

The Role of Interface Shape on the Impact Characteristics and Cranial Fracture Patterns Using the Immature Porcine Head Model, ,

The forensic literature suggests that when adolescents fall onto edged and pointed surfaces, depressed fractures can occur at low energy levels. This study documents impact biomechanics and fracture characteristics of infant porcine skulls dropped onto flat, curved, edged, and focal surfaces. Results showed that the energy needed for fracture initiation was nearly four times higher against a flat surface than against the other surfaces. While characteristic measures of fracture such as number and length of fractures did not vary with impact surface shape, the fracture patterns did depend on impact surface shape. While experimental impacts against the flat surface produced linear fractures initiating at sutural boundaries peripheral to the point of impact (POI), more focal impacts produced depressed fractures initiating at the POI. The study supported case‐based forensic literature suggesting cranial fracture patterns depend on impact surface shape and that fracture initiation energy is lower for more focal impacts.
