Utility of the Y-STR typing systems Y-PLEX 6 and Y-PLEX 5 in forensic casework and 11 Y-STR haplotype database for three major population groups in the United States

The Y-PLEX 6 and Y-PLEX 5 systems enable analysis for 11 Y-STR loci. We present here the utility of these systems in forensic casework. A total of 188 samples, including 127 evidence samples, were analyzed using either or both of the systems. The evidence sample types included fingernail scrapings, sperm or seminal fluid, epithelial cells, blood and other tissues. The Y-STR typing systems provided useful probative results in difficult cases. A reference database for Caucasian (n = 517), African American (n = 535), and Hispanic (n = 245) population groups within the United States was generated for estimating the haplotype frequency in forensic casework. Among the individuals profiled, 311 Caucasians, 412 African Americans, and 194 Hispanics provided unique profiles in their respective population datasets. This is the first report describing the haplotype database for the set of 11 Y-STR loci recommended by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Linkage analysis reveals that the frequencies from forensically important autosomal loci can be multiplied with the Y-STR haplotype frequency. The results from Y-PLEX systems have been accepted in courts in the United States.     

The matrix of complex negotiations case study： Negotiating with the Chinese at a time of crisis

This paper seeks to outline the profile of the Chinese negotiators in light of the negotiations that took place during the month of October 2008 between a major Brazilian importer of manufactured goods, which the authors will call ＂Brazilian company＂ and six Chinese companies from the cities of Guangzhou, Pinghu and Hangzhou. The authors will provide succinct examples of stages in the negotiation process and seek to link them to the ten elements of the matrix of complex negotiations, namely： context, interests, options, power, cognition, relationship, concessions, compliance, criteria and time; There are four steps involved in the process： preparation, value creation, value division and execution.     

Engendering regulation of artisanal and small-scale mining: participation,protection and access to justice

Abstract

This article argues that adopting a gender perspective when regulating artisanal and small-scale mining (ASM) is both necessary and achievable. The authors analyse women’s often-ignored needs and experiences as workers, decision-makers and affected community members in the ASM sector. To address these concerns, this article sets out standards for regulating ASM to guarantee women’s access to services and information and women’s decision-making and representation; to address the specific risks women face in the sector; and to provide access to effective remedies. The authors use international instruments to identify good practice benchmarks from which legislators and policymakers can draw. The article also notes where global norms fall short of addressing women’s rights in ASM. Some of the limitations of this approach are also acknowledged, notably the challenge of establishing gender-responsive laws that can be feasibly and effectively implemented. Nonetheless, the proposed approach should be favoured to better respond to the highly masculinised nature of the sector and the differentiated impacts of ASM on men and women while recognising women’s roles as beneficiaries and productive agents of the sector.     

Sociodemographic,Clinical, and Therapeutic Aspects of Penitentiary Psychiatric Consultation: Toward Integration Into the General Mental Health Services

The characteristics of mental disorders, as well as deficiencies in their treatment, must be properly defined. This was a prospective, longitudinal, observational study, in which all men referred to a penitentiary psychiatric consultation of three penitentiary centers in Spain were invited to participate. Those who consented to participation (1328) were interviewed at the baseline timepoint and at intervals for up to 3 years. The presence of mental disorders was high: 68.2% had a cluster B personality disorder, 14% had an affective and/or anxiety disorders, 13% had schizophrenia, and over 80% had a dual disorder. Polypharmacy was the norm. Moreover, the health care received in prison did not match that provided in the community in terms of quantity and quality. These results should help to facilitate the design of mental healthcare provision for prisoners, focusing on both the most frequent patient profiles and equality of care.     

Testing Application of Geographical Information Systems,Forensic Geomorphology and Electrical Resistivity Tomography to Investigate Clandestine Grave Sites in Colombia,South America

Colombian forensic investigators required assistance locating clandestine burials of missing persons related to human right atrocities from 14 years ago. Geoscientific search methods were trialled, including a predictive spatial statistical model, using various input and database information, to select the most likely grave locations in difficult mountainous terrain. Groundwork using forensic geomorphology, near-surface geophysics (ERT) and subsequent probing identified suspect burial positions. One site was in mountainous terrain and the other in former school grounds, both difficult to access and in poor weather conditions. In the mountainous area, a negative resistivity anomaly area was identified and intrusively investigated, found to be a buried rock. In school grounds, after MESP and intelligence were used to identify a burial site, surface depressions were identified, and ERT datasets collected over the highest priority depression; intrusive investigations discovered a hand-dug pit containing animal bones. This approach is suggested for Latin American searches.     

Evaluation of the Simultaneous Analysis of Organic and Inorganic Gunshot Residues Within a Large Population Data Set Using Electrochemical Sensors*,†

The increasing demand for rapid methods to identify both inorganic and organic gunshot residues (IGSR and OGSR) makes electrochemical methods, an attractive screening tool to modernize current practice. Our research group has previously demonstrated that electrochemical screening of GSR samples delivers a simple, inexpensive, and sensitive analytical solution that is capable of detecting IGSR and OGSR in less than 10 min per sample. In this study, we expand our previous work by increasing the number of GSR markers and applying machine learning classifiers to the interpretation of a larger population data set. Utilizing bare screen-printed carbon electrodes, the detection and resolution of seven markers (IGSR; lead, antimony, and copper, and OGSR; nitroglycerin, 2,4-dinitrotoluene, diphenylamine, and ethyl centralite) was achieved with limits of detection (LODs) below 1 µg/mL. A large population data set was obtained from 395 authentic shooter samples and 350 background samples. Various statistical methods and machine learning algorithms, including critical thresholds (CT), naïve Bayes (NB), logistic regression (LR), and neural networks (NN), were utilized to calculate the performance and error rates. Neural networks proved to be the best predictor when assessing the dichotomous question of detection of GSR on the hands of shooter versus nonshooter groups. Accuracies for the studied population were 81.8 % (CT), 88.1% (NB), 94.7% (LR), and 95.4% (NN), respectively. The ability to detect both IGSR and OGSR simultaneously provides a selective testing platform for gunshot residues that can provide a powerful field-testing technique and assist with decisions in case management.     

Average,normal, and beautiful: representations of bodies in Brazilian biotypology (1930-1940)

Th present article deals with the visual culture present in the books and textbooks on biotypology in Brazil, in the 1930s and 1940s. It analyses the representations of bodies in images, all of which were employed to guide people on the reasoning and practices of bodily measurement and classification according to the main biotypology approaches. Images herein discussed expressed the following scientific modus operandi of biotypology in Brazil: anthropometry, biometry and the construction of an average body; categorisation of biotypes, physical culture and classic aesthetic; and the link between normality, beauty and moral conceptions applied to women’s body features. This analysis also seeks to shed light on some of the ways in which biotypology strayed from and was consistent with eugenic discourse in Brazil. The representation of bodies in Brazilian biotypology showed the efforts to construct normal and deviant bodies defined according to ideals of national and racial identity, perfection, symmetry, harmony, goodness, fairness, femininity and beauty.     

Key challenges in Malawi’s paprika supply chain: new insights into contract farming

Contract farming is a vital tool for linking small-scale farmers with modern supply chains. This study explored challenges resulting from contracting in the paprika supply chain in Malawi. The study used focus groups, semi-structured interviews, and email correspondence with 100 supply chain participants. The identified challenges include: inadequate input provision via the contract, a lack of opportunities to bargain and participate in contract design, and side-selling. While the contract secured the outlet for paprika, it failed to provide a reliable paprika supply for the contracting company. Thus, Malawi’s case analyses the potential of contract farming to champion the development of vulnerable economies.     

Factors Explaining Public Participation in the Central Government Budget Process

This paper attempts to examine which factors explain public participation in the budget process in an international comparative approach. In particular, we investigate which socioeconomic, institutional, and political factors promote public engagement in the central government budget process. Using a sample of 93 countries, our results indicate that Internet penetration, population diversity, governmental financial situation, and budget transparency determine opportunities for public engagement in the central government budget process. In addition, we show that not only budget transparency promotes public participation but also public participation is necessary to enhance budget transparency.
