Criteria for the classification as a "domestic-setting corpse"--a literature search and review to define the term

In German medical and media circles (daily routine, specialist literature, press, novels), the term "domestic-setting corpse" is frequently used, but the term is only vaguely defined. The authors thus decided to perform an in-depth study of the literature, including historic textbooks and all German- and English-language medicolegal journals, going as far back as their first issues, in an attempt to more clearly define the term. Inclusion criteria used in the search were a post-mortem interval of at least 24 hours prior to discovery and discovery of the corpse in a domestic setting. In the literature, 37 cases that complied with the above-mentioned inclusion criteria were found. These cases frequently described "advanced decomposition", often "unclear cause of death" and "problems in identification". These characteristics can thus be considered as being additional pointers in the definition. However, we suggest that the two general defining characteristics of a "domestic-setting corpse" are a post-mortem interval of more than 24 hours before discovery and the discovery of the corpse in a domestic setting.     

Procedural justice during police-citizen encounters: The effects of process-based policing on citizen compliance and demeanor

Purpose

Theories of procedural justice have facilitated the development of a process-based approach to policing which emphasizes the fairness of the manner in which the police exercise their discretion. The study examines whether procedurally fair behavior by the police affects two types of citizen behavior during encounters: citizen disrespect toward the police and citizen noncompliance with police requests.

Methods

This study uses data from systematic social observations of police-citizen encounters to examine procedural justice factors on citizen behavior. Because of the reciprocal nature of police-citizen interactions, an instrumental variable is used in the statistical analysis to help address the causal relationship between police force and citizen disrespect.

Results

The statistical analyses find limited support for procedural justice factors. Two types of procedurally fair behavior by the police, police demeanor and their consideration of citizen voice, are significant in reducing citizen disrespect and noncompliance, respectively.

Conclusion

Procedural justice factors have limited and inconsistent impacts on the two types of citizen behavior, and future research should address the limitations of this study and evaluate process-based policing with more data from social observations of police-citizen encounters.     

Risky Lifestyle as a Mediator of the Relationship Between Deviant Peer Affiliation and Dating Violence Victimization Among Adolescent Girls

Few studies have explored the possible contribution of the peer group to dating violence victimization. The current study tested the hypothesis that a risky lifestyle would mediate the relationship between deviant peer affiliation and dating violence victimization among adolescent girls. The proposed mediation model was derived from lifestyles and routine activities theories. A sample of 550 girls (mean age = 15) drawn from a larger representative community sample in Quebec, Canada, completed a questionnaire on three forms of dating violence victimization (psychological, physical, and sexual). Results revealed that girls with a higher level of affiliation with deviant peers were more likely to endorse a risky lifestyle and reported higher rates of all forms of dating violence victimization. Further analyses showed that, while deviant peer affiliation is associated with dating violence victimization, this relationship may be explained, at least partially for psychological violence, and completely for physical/sexual violence, by the girls’ own risky lifestyle. Future preventive interventions for adolescent dating violence victimization should target deviant peer groups, as well as adolescent girls who display a risky lifestyle.     

Single cells for forensic DNA analysis--from evidence material to test tube

Abstract: The purpose of this project was to develop a method that, while providing morphological quality control, allows single cells to be obtained from the surfaces of various evidence materials and be made available for DNA analysis in cases where only small amounts of cell material are present or where only mixed traces are found. With the SteREO Lumar.V12 stereomicroscope and UV unit from Zeiss, it was possible to detect and assess single epithelial cells on the surfaces of various objects (e.g., glass, plastic, metal). A digitally operated micromanipulator developed by aura optik was used to lift a single cell from the surface of evidence material and to transfer it to a conventional PCR tube or to an AmpliGrid^® from Advalytix. The actual lifting of the cells was performed with microglobes that acted as carriers. The microglobes were held with microtweezers and were transferred to the DNA analysis receptacles along with the adhering cells. In a next step, the PCR can be carried out in this receptacle without removing the microglobe. Our method allows a single cell to be isolated directly from evidence material and be made available for forensic DNA analysis.     

Reverse engineering--rapid prototyping of the skull in forensic trauma analysis

Rapid prototyping (RP) comprises a variety of automated manufacturing techniques such as selective laser sintering (SLS), stereolithography, and three-dimensional printing (3DP), which use virtual 3D data sets to fabricate solid forms in a layer-by-layer technique. Despite a growing demand for (virtual) reconstruction models in daily forensic casework, maceration of the skull is frequently assigned to ensure haptic evidence presentation in the courtroom. Owing to the progress in the field of forensic radiology, 3D data sets of relevant cases are usually available to the forensic expert. Here, we present a first application of RP in forensic medicine using computed tomography scans for the fabrication of an SLS skull model in a case of fatal hammer impacts to the head. The report is intended to show that this method fully respects the dignity of the deceased and is consistent with medical ethics but nevertheless provides an excellent 3D impression of anatomical structures and injuries.     

The effects of corrosive substances on human bone, teeth, hair, nails, and soft tissue

Abstract: This research investigates the effects of household chemicals on human tissues. Five different human tissues (bone, tooth, hair, fingernails, and skin/muscle/fat) were immersed into six different corrosive agents. These agents consisted of hydrochloric acid, sulfuric acid, lye, bleach, organic septic cleaner, and Coca‐Cola^® soda. Tap water was used as a control. Tissue samples were cut to consistent sizes and submerged in the corrosive liquids. Over time, the appearance, consistency, and weight were documented. Hydrochloric acid was the most destructive agent in this study, consuming most tissues within 24 h. Sulfuric acid was the second most destructive agent in this study. Bleach, lye, and cola had no structural effects on the hard tissues of the body, but did alter the appearance or integrity of the hair, nails, or flesh in some way. The organic septic cleaner and tap water had no effect on any of the human tissue tested during the timeframe of the study.     

Modifying children's court care plans to acknowledge poverty and disadvantage

This think piece suggests that Children's Court Care Plans should include a new section that documents poverty and social disadvantage, especially of Aboriginal and Torres Strait Islander families, when they are under investigation for child abuse and neglect. New South Wales in Australia is used as the exemplar state, but this suggestion may find an echo elsewhere.

Points for practitioners

• As a general proposition social and economic circumstances should be considered in addition to parental dysfunction in child protection proceedings in Children's court.
• Care Plans prepared for hearings in the NSW Children's Court, often developed in response to serious harm report investigations, currently do not contain information about parents' poverty and social disadvantage and hence decontextualise family living circumstances.
• Consistent with international evidence, Care Plans should require information about parents' socioeconomic situation, including social disadvantage of residential neighbourhood, status and cost of household tenancy, and household income.
• Taking account of social and economic circumstances has the potential to generate savings in out-of-home care that can be re-allocated to support services to reduce poverty and social disadvantage and thereby reduce the need for removal of children from parental care.

     

Issue opacity and sustainability standard effectiveness

Many voluntary sustainability standards govern opaque environmental and social issues, which are difficult to understand and address. Extant studies show mixed evidence around the effectiveness of such standards. We develop a theoretical framework that relates different degrees and types of opacity to standard effectiveness. Systemic opacity results from issues embedded in complex, diverse, and dynamic settings, whereas behavioral opacity stems from human challenges in interpreting and acting upon focal issues. Rigid sustainability standards, oriented toward compliance, are effective for addressing issues that are transparent or enshrouded by behavioral opacity, but are counterproductive for issues with systemic opacity. The trade-off between rigidity and flexibility leads to optimal effectiveness when standards governing systemically and behaviorally opaque issues are moderately rigid. Our ideas are illustrated with two leading sustainability standards in the fisheries and real estate sectors, which effectively address transparent issues but show limited success when facing opacity. We conclude that unpacking issue opacity is instrumental in designing and implementing more effective sustainability standards.
