Genetic diversity at two pentanucleotide STR and thirteen tetranucleotide STR loci by multiplex PCR in four predominant population groups of central India

Genetic diversity study at STR loci in 208 individuals belonging to two backward groups, one caste and one tribal community of Central India called "Chhattisgarh" has been carried out to evaluate significance of Powerplex System loci in human identification and population diversity. Populations are Agharia (72), Satmani (50), Dheria Gond (36) and Teli (50). Fifteen loci (Powerplex 16 Kit) studied are Penta E, D18S51, D21S11, THO1, D3S1358, FGA, TPOX, D8S1179, vWA, Amelogenin, Penta D, CSF1PO, D16S539, D7S820, D13S317 and D5S818. The studied penta nucleotide STR (two) and 13 tetranucleotide (CODIS ) STR are found to be highly polymorphic genetic markers in all studied populations. Most common allele for the four studied population has been found to be same at THO1 (allele 9), D8S1179 (allele 14), CSF1PO (allele 12), Penta E (allele 11) and D16S539 (allele 11). Penta E is found to be most polymorphic (PD=0.89373) among studied 15 STR loci in four populations of Central India.     

Application of DNA Forensic Techniques for Identifying Poached Guanacos (Lama guanicoe) in Chilean Patagonia*

Abstract: Guanaco (Lama guanicoe) is a protected and widely distributed ungulate in South America. A poacher, after killing guanacos in Valle Chacabuco, Chilean Patagonia, transported and stored the meat. Samples were retrieved by local police but the suspect argued that the meat was from a horse. Mitochondrial cytochrome b gene (774 pb), 15 loci microsatellites, and SRY gene were used to identify the species, number of animals and their population origin, and the sex of the animals, respectively. Analysis revealed that the samples came from a female (absence of SRY gene) Patagonian guanaco (assignment probability between 0.0075 and 0.0282), and clearly distinguishing it from sympatric ungulates (E‐value = 0). Based on the evidence obtained in the field in addition to forensic data, the suspect was convicted of poaching and illegally carrying fire arms. This is the first report of molecular tools being used in forensic investigations of Chilean wildlife indicating its promising future application in guanaco management and conservation.     

Crime trends and the effect of mandated drug treatment: Evidence from California's Substance Abuse and Crime Prevention Act

The Substance Abuse and Crime Prevention Act (SACPA), implemented statewide in California in July 2001, mandates drug treatment rather than incarceration for certain nonviolent drug offenders. Critics of the legislation suggest that crime increased as a result of the legislation, but researchers have largely ignored this issue. Utilizing time series methodology applied across several independent data sets from Orange County, California, the effects of SACPA on crime were assessed. Results indicate that significant increases in commercial burglaries and paraphernalia arrests may have been attributed to SACPA, but the overall pattern does not support a conclusion that crime increased markedly.     

The Downside of Patriarchal Benevolence: Ambivalence in Addressing Domestic Violence and Socio-Economic Considerations for Women of Tamil Nadu,India

Social values and status cause diverse obstacles for escaping abuse (e.g., belief in the sanctity of marriage vs. financial necessity to stay for survival). India provides a unique opportunity to explore the interplay of status and corresponding patriarchal values in relation to the incidence of domestic violence and how it is viewed, coped with, and psychologically impacting native women. Sixty-four women of Tamil Nadu, India were surveyed. Women of higher status were found to be less likely to acknowledge abuse as a societal problem, accurately identify abuse events, and seek help or report abuse. Women who had more realistic conceptions of abuse were more likely to seek help but also likely to experience more severe psychological distress. All of the women surveyed had symptoms of post-traumatic stress disorder that were exacerbated by unsuspected variables. The implications of these findings are discussed in light of public health strategies.     

Detecting Specialization in Offending: Comparing Analytic Approaches

Offending specialization continues to be a subject of empirical inquiry for scholars interested in criminal careers. Early research consistently spoke to the generality of offending profiles, but more recent work has revealed somewhat mixed findings. These results have emerged alongside newly developed and applied methods that detect and describe offending specialization. To what extent these methods shape divergent conclusions and/or provide overlapping insight remains unclear, however. Therefore, the degree to which more recent inquiries are actually studying the same operational definition of specialization is unknown. In order to consider this issue further, this study utilizes four frequently applied approaches with a single data set. The study indicates when and where findings converge and also describes any unique insights provided by each method. The work concludes with a discussion surrounding the utility of applying multiple strategies in assessing specialization in criminal offending.     

Unintended consequences: experimental evidence for the criminogenic effect of prison security level placement on post-release recidivism

Most prison systems use quantitative instruments to classify and assign inmates to prison security levels commensurate to their level of risk. Bench and Allen (The Prison Journal 83(4):367-382, 2003) offer evidence that the assignment to higher security prisons produces elevated levels of misconduct independent of the individual’s propensity to commit misconduct. Chen and Shapiro (American Law and Economics Review, 2007) demonstrate that assignment to higher security level among inmates with the same classification scores increases post-release recidivism. Underlying both of these claims is the idea that the prison social environment is criminogenic. In this paper we examine the theoretical premises for this claim and present data from the only experiment that has been conducted that randomly assigns inmates to prison security levels and evaluates both prison misconduct and post-release recidivism. The experiment’s results show that inmates with a level III security classification who were randomly assigned to a security level III prison in the California prison system had a hazard rate of returning to prison that was 31% higher than that of their randomly selected counterparts who were assigned to a level I prison. Thus, the offenders’ classification assignments at admission determined their likelihood of returning to prison. There were no differences in the institutional serious misconduct rates of these same prisoners. These results are contradictory to a specific deterrence prediction and more consistent with peer influence and environmental strain theories. These results also raise important policy implications that challenge the way correctional administrators will have to think about the costs and benefits of separating inmates into homogeneous pools based on classification scores.

Identification and analyses of female civilian victims of the 1991 war in Croatia from the Glina and Petrinja areas

Introduction

The process of recovering and identifying human remains from individual and mass graves has proven to be the most effective method of resolving the fate of missing individuals in the former Yugoslavia. These efforts have two primary objectives: medicolegal—to identify the cause of death, and humanitarian—to bring closure to living family members, thus supporting the human rights of both the living and the deceased. From 1996 to the present, the remains of 388 individuals killed during the 1991 War in Croatia were recovered from the Glina and Petrinja areas (Sisa?ko–Moslova?ka County). The purpose of this paper is to report on the demographic and taphonomic characteristics of the recovered remains, and identify factors responsible for the discrepancy in the identification ratios.

Methods

To identify factors potentially responsible for the noted discrepancy, data were collected on the taphonomic characteristics of the recovered remains, the types of burials, as well as the factors responsible for positive identification. These factors included: forensic DNA testing, dental criteria, special signs (healed fractures, etc.), clothing and personal artifacts.

Results

The age distributions between males and females in the sample are significantly different. The mean age-at-death for males is 51.6 years, for females 67.0 years. In both sexes the majority of identifications (62.9% in females and 45.9% in males) were established through a combination of biological and non-biological features. In terms of the types of graves from which the bodies were recovered, positive identification in both sexes was lowest in mass graves (61.2% for males, and 84.2% for females). Females from mass graves were, however, better preserved than males—36.6% of males recovered from mass graves were completely skeletonized, while the same was true for only 19.3% of females (χ² = 7.06, P < 0.029). Completely skeletonized remains were identified in only 65.1% of cases, while partially skeletonized and saponified bodies were identified in 80.1% of cases.

Conclusion

Since positive identification in both sexes is strongly correlated with preservation of the bodies, the reason why female identification frequencies in the Glina and Petrinja regions are higher than male frequencies lies in the fact that females recovered from mass graves were better preserved than males recovered from mass graves. Identification of the factors responsible for this is a challenge that needs to be resolved in future studies.     

Forensic application of Y chromosome SNPs in inconclusive cases

Biallelic markers, Single Nucleotide Polymorphisms (SNPs), are nowadays a powerful tool in the analysis of degraded samples. Namely, Y chromosome SNPs allow to determine the gender of the analyzed sample and to establish its haplogroup, making possible to attribute the ethnicity of male individuals. The aim of this study is to obtain Y-SNPs in forensic samples without STRs results, checking methodologies previously used.
