In this article, we examine gang membership and gang activity in Dona Ana County, New Mexico. We collected the data through a self-administered questionnaire completed by 373 randomly selected 9th and 11th grade students attending two high schools and two junior high schools. By the self-report method, 56 indicated they were currently active in a gang; another 45 had been members of gangs but were no longer involved; and, “wannabes,” or students who at some time had considered joining a gang but did not or could not, totaled 68. The 169 students who indicated some interest in or involvement with gangs represented 45% of the total sample. A more restrictive definition of actual gang membership (i.e., the group must have initiation rites and employ some external symbols of membership, such as “colors,” tattoos, or handsigns) results in a different trichotomization. We employ both the self-definition and restrictive definition of gang membership in our analysis of their personal biographical characteristics and criminal behavior. Our findings suggest that self-definition demonstrates clearer ties to self-reported gang-related activities than does the more restrictive one. We discuss the policy implications of this finding in the article. 相似文献

A new pentaplex system to study short tandem repeat markers of forensic interest on X chromosome 总被引:16,自引:0,他引:16

A new method has been optimised to amplify five X chromosome short tandem repeat (STR) markers of interest in forensic medicine: human phosphoribosyl transferase (HPRTB), DXS101, androgen receptor (ARA), DXS7423 and DXS8377. Markers were conveniently amplified in a single PCR reaction with fluorochrome-labelled primers, which allowed the analysis of fragment sizes after injection into a capillary electrophoresis system. The most common alleles of each locus were sequenced and used in a control ladder to type unknown samples. 相似文献

Selenium is one of the most toxic elements necessary for the life of mammals. Only a narrow range separates therapeutic (connected with a protective effect) and toxic doses. Selenium incorporated into animal or human tissues in larger amounts can exceed normal human levels and may be toxic (only elemental selenium and selenium sulphide are poorly absorbed). Acute poisonings with selenium or its compounds, especially fatal ones, occur extremely rarely in humans. Levels of selenium in four fatal cases are reviewed, and the levels in a fatal poisoning with sodium tetraoxoselenate(VI) are evaluated. Postmortem tissue selenium contents in the latter case were the following: brain, 1.45 and 1.60 microg/g; stomach, 6.12 and 6.37 microg/g; small intestine, 4.37 and 4.13 microg/g; large intestine, 4.53 and 4.43 microg/g; liver, 4.20 and 4.35 microg/g; kidney, 3.35 and 3.60 microg/g; lung, 1.80 and 1.60 microg/g; blood, 1.43 and 1.41 microg/ml measured by the use of ETA-AAS and fluorimetric methods, respectively. 相似文献

Capital punishment, although opposed by numerous scholars and banned in several countries, continues to be practiced in many locations under a popular rationale associated with retributive justice. While there has been extensive debate on this issue for decades among scholars, policymakers, correctional professionals, and the media; other important voices, specifically the voices of family members of executed convicts, have been ignored or discounted. Situated within a convict criminology perspective, this paper focuses on a personal narrative of how the issue of capital punishment was experienced by the partner (second author of this paper) of an executed convict. This narrative powerfully illustrates complexities and unintended social injustices toward family members that can occur from capital punishment. 相似文献

Soil is useful in criminal investigations as it is highly variable and readily transferred. Forensic geologists use several different techniques to removal soil from evidence prior to the analysis of inorganic components. There has been recent interest from the forensic science community to analyze environmental deoxyribonucleic acid (eDNA) associated with soil to augment existing forensic analyses. Notably however, limited research has been conducted to compare commonly used soil removal methods for downstream eDNA analysis. In this study, three soil removal methods were assessed: picking/scraping, sonication, and swabbing. Three mock evidence types (t-shirts, boot soles, and trowels) were sampled in triplicate with each removal method (n = 27). Soil samples underwent DNA isolation, quantification, and amplification of four genomic barcode regions: 16S for bacteria, ITS1 for fungi, ITS2 for plants, and COI for arthropods. Amplicons were prepared into libraries for DNA sequencing on an Illumina® MiniSeq. DNA concentrations were highest in picked/scraped samples and were statistically significant compared with swabbed and sonicated samples. Amplicon sequence variants (ASVs) were identified, and removal methods had no impact on the recovery of the total number of target ASVs. Additionally, when assessing each sample in multidimensional space, picked/scraped samples tended to cluster separately from swabbed and sonicated samples. The soil core used a reference in this study also clustered with the picked/scraped samples, indicating that these samples may be more reflective of the communities collected from soil cores. Based on these data, we identified that picking/scraping is an acceptable soil removal method for eDNA analysis. 相似文献

This article explores perceived shifts in roles for NGOs and religious actors after the creation of the Palestinian National Authority with the 1993 Oslo Accords, using original data from a survey of more than 1,000 community members in the West Bank and Gaza. The survey data show a centralisation of requests for assistance from the Palestinian National Authority, with a decrease in requests from local government, NGOs, and religious actors after the creation of the Palestinian National Authority. The support the empirical findings lend to theories of government and voluntary failure is discussed. 相似文献

In this article, we empirically investigate the validity of the contract failure arguments as applied to a segment of the child care industry. However, prior research has focused upon actual quality differences between nonprofit and for-profit providers whereas the theory is concerned with consumers' perceptions of quality differences. In the current study, we examine both consumers′ perceptions and actual performance in testing the theory. In general, the data provide support for contract failure. 相似文献

Laws named after specific crime victims have become increasingly common. These laws are part of a broader effort to downgrade the status and rehabilitative needs of offenders and to hear the voices and trumpet the legitimate concerns of victims—often as a means of justifying punitive crime control policies. Beyond the substantive merit of individual statutes, collectively these named laws provide a clear image of which victims warrant protection and memorialization: Victims who are vulnerable in some way, who are pursued by predatory criminals into their otherwise safe domains, and—above all—who are White. In this regard, an analysis of 51 named laws from 1990 to 2016 reveals that the vast majority of them (86.3%) honor White victims. In asking the question, “Where is Latisha’s Law?,” we seek to illuminate the virtual invisibility of African American victims and the implicit social construction of which lives matter more in American society. 相似文献
