Volume Determination of Fresh and Dried Bloodstains by Means of Optical Coherence Tomography

The volume of bloodstains found on crime scenes may help forensic investigators reconstruct the location and kinematics of bloodletting events, as stain size, volume, and impact velocity are related. Optical coherence tomography was used as a method to determine the volume and volume ratio of dried and fresh bloodstains on both glass and irregular surfaces or deposited with an impact velocity. The volume of blood drops deposited on smooth glass surfaces was measured within a deviation of 2%. This deviation increased for droplets on irregular surfaces or deposited with an impact velocity. The volume ratio of dried and fresh bloodstains was equal to 19–28% depending on the individual donor and on the use of an anticoagulant. Optical coherence tomography is a good method to determine the volume of fresh and dried bloodstains in laboratory conditions and allows accurate determination of the dry/fresh ratio.     

A Molecular Method to Correlate Bloodstains with Wound Site for Crime Scene Reconstruction

Bloodstain pattern analysis to determine the wound‐of‐origin of bloodstains is problematic with nonspecific patterns. In this proof‐of‐concept study, the authors examined a molecular approach to correlate bloodstains with injuries using the rat as a model. Specifically, investigations were conducted on the rat brain marker, rno‐miR‐124‐3p, with the QIAGEN miScript System and real‐time PCR analysis. Rno‐miR‐124‐3p was detected in brain homogenates diluted 100,000 times; in 3‐week‐old, room temperature stored, simulated brain–blood stains; and in bloodstains from head gunshot wounds collected with swabs and subsequently frozen for 9–18 months; however, rno‐miR‐124‐3p was not detected in whole blood. Proof‐of‐principle was demonstrated by the ability to distinguish bloodstains from a gunshot wound to the head versus bloodstains from a gunshot wound to the chest, by the testing of otherwise identical bloodstains from the two patterns for the presence of the marker. The results suggest a viable approach to a longstanding problem in casework.     

Ketoacidosis and Adrenocortical Insufficiency

We herein report an autopsy case involving a 27‐year‐old Caucasian woman suffering from chronic adrenocortical insufficiency with a background of a polyendocrine disorder. Postmortem biochemistry revealed pathologically decreased aldosterone, cortisol, and dehydroepiandrosterone levels in postmortem serum from femoral blood as well as decreased cortisol and 17‐hydroxycorticosteroid in urine. Decreased vitreous sodium and increased 3‐beta‐hydroxybutyrate and C‐reactive protein concentrations were observed. The cause of death was determined to be acute adrenocortical insufficiency. Fasting ketoacidosis was postulated to have precipitated the Addisonian crisis. Traumatic causes of death and third‐party involvement were excluded. The case highlights the importance of systematically performing exhaustive postmortem biochemical investigations to formulate appropriate hypothesis regarding the pathophysiological mechanisms involved in the death process.     

Remittances,Banking Status and the Usage of Insurance Schemes

Empirical evidence that migrants send home more remittances after disasters raises the question of whether remittances are used to self-insure, substituting for both formal and informal insurance. We investigate this question using a unique data set on the usage patterns of financial services by households in South Africa. We show that the likelihood that a respondent has a formal funeral cover increases with income and banking status. However, it is lower for individuals receiving remittances, which supports the idea that remittances act as self-insurance. We also show that other risk management strategies influence the purchasing of formal funeral cover. Finally, we find that determinants of informal insurance differ from those of formal insurance.     

Resilience and Criminal Justice: Unsafe at Low Altitude

Resilience is increasingly featuring in crime and justice policy discussions. It appears in the fusion of military, security and criminal justice. It offers an alignment by which individual actors are to be adaptive to the uncertain conditions of high risk societies. This article unpacks the application of resilience to criminal justice to reveal at least one negative implication: by placing the focus on self-directed change resilient subjects have limited transformative power. The concept of resilience involves discounting a longer view that challenges the dominant social institutions and orders of neoliberalism. In contrast, we propose the dignified subject and the re-assertion of the discounted institutional context at a level above the individual and community. This analysis supports renewing the transformative agenda of a critical criminology.     

Opening the Black Box Between Justice and Reactions to Unfavorable Outcomes in the Workplace

Though several studies have shown that the perception of social justice can effectively reduce negative attitudinal and behavioral reactions to an unfavorable outcome, few studies have tried to empirically test explanations of this mitigating effect. The present study was undertaken to fill this gap by examining under what conditions social justice suppresses negative reactions, such as exit, neglect, and aggressive voice, and stimulates positive reactions, such as considerate voice and patience. Two potential moderators were derived from the control model (Thibaut and Walker, 1975, 1978) and the group-value model (Lind and Tyler, 1988, Tyler and Lind, 1992). Ninety-eight teachers participated in the study. Results support the hypotheses that overall procedural and distributive justice discourage negative reactions, particularly when employees value control or standing, or both. Moreover, distributive justice stimulates positive reactions (i.e., considerate voice) when employees value control. Theoretical and practical implications of these findings are discussed.
