The perceived impact of a child maltreatment report from the perspective of the domestic violence shelter worker

The purpose of this study is to examine domestic violence shelter workers' perceptions of child maltreatment reporting. A sample of 82 professionals from domestic violence shelters across the United States participated in a survey focusing on a variety of different types of reports and the frequency of both positive and negative outcomes arising from these reports. Possible outcomes included in the study are damage to the relationship between the worker and the battered woman, disempowerment of the battered woman, discouragement from seeking further help, protection of the child, further traumatization of the child, further disruption to the family, and damage to the woman's likelihood of maintaining custody. Significant differences in perceived impact are found based on identity of abuser (spousal batterer vs. battered woman) and nature of report (child as witness to domestic violence vs. child as victim of abuse). These results point to the complexity of perceptions regarding the impact of reporting.     

Dominance of pre-analytical over analytical variation for measurement of methadone and its main metabolite in postmortem femoral blood

On the basis of simultaneously sampled postmortem blood specimens from the left and right femoral veins the pre-analytical variation of methadone measurements was evaluated and compared to the analytical variation. The material consisted of a series of 27 duplicate samples from routine autopsy cases comprising mainly drug addicts. A chiral LC-MS/MS method was used for measurement of the R- and S-enantiomers of methadone and its main metabolite 2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolinium (EDDP). The analytical CV% was determined to be in the range 3-4% for methadone enantiomers and 4-6% for EDDP enantiomers. The total measurement uncertainty (CV(T)) was estimated from the pre-analytical variation (CV(PA)), analytical variation proper (CV(A)), and variation related to calibration (traceability) (CV(Cal)) according to the relationship CV(T) = [CV(2)(PA) + CV(2)(A) + CV(2)(cal)](0.5). Uncertainty related to calibration concerned a component related to the purity of drug reference compound and a contribution from the production of calibrator solutions (CV(Cal)<1%). Pre-analytical sampling variation was estimated from the duplicate measurements of blood samples after subtraction of the analytical component. The pre-analytical variation amounted to a CV% of 19-21% for R- and S-methadone and 30-38% for R- and S-EDDP, i.e. considerably larger than the other components. Due to the squared addition principle, the resulting total uncertainty (CV(T)) became largely identical to the CV(PA), i.e. 19-21% for R- and S-methadone and 31-38% for R- and S-EDDP enantiomers. Accordingly, CV(T) exceeded CV(A) by a factor 5 or more. Dominance of the pre-analytical component of variation may also be likely for other compounds measured in postmortem blood samples. Thus, the width of the 95%-uncertainty interval (+/-2CV(T)) for a postmortem measurement is largely determined by the pre-analytical component of variation. This should be kept in mind when judging on the uncertainty of postmortem measurement results.     

Magnetic law: Designing environmental enforcement laws to encourage us to go further

The European Union has some of the world's most ambitious and highly developed environmental laws on its books, but their effectiveness is severely compromised by non-compliance. With the UNECE Aarhus Convention (1998), Europe launched an innovative legal experiment, democratizing environmental enforcement by conferring third party citizens and environmental non-governmental organizations (ENGOs) with legal rights of access to environmental information, public participation, and access to justice in environmental matters. Based on some 2000 surveys and over 150 interviews with stakeholders from three Member States – France, Ireland, and the Netherlands – we adopt a holistic, 360° perspective, capturing the views of regulated parties, NGOs, and the general public on this private governance experiment. Our data provide important new insights into the practical effectiveness of Europe's laws enabling private environmental enforcement, its (intended and unintended) effects on farmers' compliance decisions in the vital area of nature conservation, and how law might be used to stimulate pro-environmental predispositions.     

The discrimination of automotive clear coats by pyrolysis-gas chromatography/mass spectrometry and comparison of samples by a chromatogram library software

Identification particles used for the purpose of the post-blast identification of explosives have a coding system based on the combination of metal oxides and their various concentrations. These materials are composed of the polymeric matrix, iron powder (ferromagnetic properties), UV light active dyestuff and various metal oxides in a various ratios. A suitable analytical method has to be used for an accurate characterization of these metal components in the particles in order to find the required information, i.e. to determine the place and the year of production and as the case may be, also the production batch of misused explosives. In this work, the method of microwave digestion and flame atomic absorption spectrometry (F-AAS) was developed for an accurate determination of Zn, Mg, Cu and Pb in a few novel types of identification particles and applied to their characterization. When using specific sample treatment (digestion with a mixture of nitric acid with hydrochloric or hydrofluoric acid), the 3 sigma limits of detection (LODs) for the determination of Zn, Mg, Cu and Pb in 5mg original samples were 1.9, 0.2, 1.3 and 2.4 mg g(-1), respectively. The signal suppression due to the presence of HNO3+HCl or HNO3+HF was observed for Zn; therefore, the calibration solutions had to be prepared exactly with the same acids as those used for the sample mineralization. The determination of Mg, Cu and Pb was free of interferences; hence a simple calibration curve method could be adopted for attaining accurate results. The accuracy was checked by comparison of the results with those obtained by means of independent inductively coupled plasma optical emission spectrometry (ICP-OES). Good precision values, as relative standard deviation, in the range of 1-5% were obtained. A total number of 71 samples was analysed and classified by multivariate methods to prove the suitability of the procedure proposed for the purpose of the identification of explosives.     

The impact of suicide on the family

Little research has examined the consequences of a suicide for social or family networks. Because suicide occurs within families, the focus on the aftermath of suicide within families is an important next step to determine exactly how to help survivors. In this article, we review and summarize the research on the impact of suicide on individuals within families and on family and social networks. We begin with a discussion of family changes following suicide. Next, we discuss the effects of suicide on social networks overall and responses of children and the elderly to a suicide in the family. Finally, we identify key issues that remain to be resolved in family survivor research and make recommendations for future studies.     

Anthropological analyses of 30 insertion/deletion autosomal markers in five major ethnic groups of Pakistan

We investigated the forensic efficacy of the 30 insertion/deletion (Indel) markers included in the Qiagen Investigator® DIPplex kit in 529 Pakistani individuals from five major subpopulations in Pakistan (Punjabi, Pashtun, Sindhi, Saraiki, and Baloch). In the Sindhi population, the distribution of HLD81 and HLD97 alleles deviated from Hardy-Weinberg equilibrium after Bonferroni correction. The combined match probability ranged from 2.0E-12 (Pashtun and Baloch) to 1.0E-12 (Sindhi), and the mean paternity exclusion power varied from 0.995 (Punjabi, Sindhi, and Saraiki) to 0.996 (Pashtun and Baloch). The high combined power of discrimination (0.999 999 999 999 97) and low combined match probability (1.7E-12) for all subpopulations studied support the utility of the 30 Indel markers for forensic identification in the studied subpopulations. The allele frequencies of the Indel markers in the Pakistani subpopulations were compared with those from 18 other populations. The results show that the populations clustered according to geography. The subpopulations investigated in this work showed a close genetic relationship with others from Pakistan, as well as with South Central Asian and Middle Eastern populations. The results suggest that the Investigator^® DIPplex kit can be useful as a supplementary tool for human identification in the five Pakistani subpopulations investigated in this study.Supplemental data for this article is available online at https://doi.org/10.1080/20961790.2021.1933366 .

The significance of anticipating suspected brain death for the accusation of failure to treat according to Section 323c of the Federal Penal Code

Brain death is usually not confirmed by neurological and angiographical techniques until long after it has actually taken place. In connection with a case in which expert testimony was heard, clinical and radiographic evidence and the autopsy statement are discussed as criteria of continuing development of brain edema; on the basis of the evidence it was possible to conclude that the cerebral circulation had not yet ceased at the time assumed.
