Human hairs are one of the most commonly encountered items of trace evidence. Currently, conventional methods for hair analysis include microscopic comparison and DNA analysis (nuclear and mitochondrial). Each approach has its own drawbacks. Hair proteins are stable and offer an alternative to DNA testing, as demonstrated with proteomics for distinguishing humans. However, proteomics is complicated and requires identifying peptides to remain intact following harsh sample preparation methods. Alternatively, the actual amino acid content of a hair sample may also offer important identifying information and actually requires proteins and peptides to be broken down completely rather than remaining intact. This study evaluated the discriminating power of using hair amino acid ratios to differentiate hair samples from 10 unrelated individuals with dark colored hair. Hair proteins were digested, derivatized, and analyzed using gas chromatography–mass spectrometry. Amino acid ratios were calculated for each individual and comparisons using ANOVA and post-hoc pairwise t-test with Bonferroni correction were made with amino acid ratios for individuals. Overall, out of the 45 possible pairwise comparisons between all hair samples, 38 (84%) were differentiable. Out of the 36 possible pairwise comparisons between brown haired individuals, 32 (89%) were considered differentiable using univariate statistics. Multivariate statistics were also attempted but, overall, univariate models were sufficient for exclusionary purposes. These results indicate that amino acid ratio analysis can potentially be used as an exclusionary method using hair if DNA analysis cannot be performed, or to corroborate conclusions made following microscopic analysis.  相似文献

This article demonstrates that World Bank internal learning has led to significant changes in how the organization interacts with government officials through survey missions. Reviewing evidence of institutional learning and associated changes in practice and focusing on the relational modes being manifest in technical assistance, the article identifies three main phases of World Bank survey missions: general survey missions (1940s–1960s), country assistance strategies (1990s–2000s), and country partnership frameworks (2010s). Overall, World Bank reviews have repeatedly highlighted the importance of non-hierarchical interactions between Bank staff and country officials. In recent years, practice has begun to catch up with these operational insights.  相似文献

This analysis charts the changes in British aid policy under the Margaret Thatcher government (1979–1990). In particular, it examines the impact of so-called neo-liberal ideology in overseas development strategy in an era where “structural adjustment”—aid in return for market-based reforms—became World Bank and International Monetary Fund orthodoxy. There is some evidence to show British increases in multilateral aid during the 1980s supported a neo-liberal aid policy. Bilateral aid policy, however, demonstrated a subordination of aid to foreign policy and a pro-business—not ideologically pro-market or neo-liberal—alignment. One of the results of these structural changes was the Pergau Dam scandal at the end of the Thatcher years.  相似文献

This study explored whether the rational (certainty of punishment) and nonrational (criminal thinking) aspects of antisocial decision‐making interact. A convenience sample of 319 undergraduates (106 men, 213 women) completed a measure of criminal thinking and responded to three fictional vignettes (i.e., cheating on a final examination in a class they were in jeopardy of failing, stealing $50 off a table in a dorm room, and selling marijuana for a friend) at three different levels of risk or certainty of apprehension (50%, 10%, and 1%). Results indicated that participants reported that they would be more likely to engage in antisocial behavior when the certainty of getting caught was low and the level of proactive (P) or reactive (R) criminal thinking was high. An interaction between certainty and criminal thinking was also observed in which the gap between lower and higher criminal thinking respondents grew as the probability of getting caught fell.  相似文献

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.  相似文献

Interest in the relationship between autism and violence has increased in recent years; however, no link has clearly been established between them. Researchers remain curious if autistic people with certain traits (e.g., a history of trauma) are at greater risk of violence than those individuals with autism alone. In this article, we detail two individuals with homicidal ideation (HI) admitted to inpatient psychiatric units who were found to have a diagnosis of autism without language impairment. These cases illustrate the need for mental health providers to consider autism in their differential diagnosis when evaluating an individual with HI. Broadly, we consider how an autistic individual could be susceptible to developing HI and explore treatments specific to autistic individuals that may be helpful in such cases.  相似文献

Spatial patterns of murder and physical injury in Metro Manila, Philippines were visualised through conditional choropleth maps. Relationship of both crime rates with some demographic variables were investigated while accounting for possible spatial autocorrelation using spatial lag models. Results show that both crime rates tend to cluster in the northern cities of Metro Manila. Furthermore, significant spatial lag coefficients were found only for physical injury rates, with values ranging from 0.49 to 0.62, signifying a positive city-level spatial dependence of physical injury rates in Metro Manila. Moreover, some demographic covariates, such as population density, percentage of young males, education, marriage, and immigration were found to be associated with both crime rates. These results could serve as useful indicators of crime incidence; thus it is recommended that crime monitoring systems include them to aid in resource allocation and program planning for better crime prevention and security management.  相似文献

This paper shares results of a study of judgments applying the common law as adapted to the cohabitation context. Specifically, the Supreme Court of Canada has held that couples who formed a ‘joint family venture’ may need to share the wealth gained during cohabitation. The study compares the couples leading to positive and negative findings of a joint family venture. Positive findings correlate with traditional markers of family and economic integration, such as joint bank accounts and the presence of children. Despite the discourse of family diversity, gendered patterns run across all the couples, with women assuming primary care of children, shouldering domestic labour, and making career sacrifices for the family. In a sign of the limits of judge-made reforms, the doctrine may be harder for some claimants to access than for others, in ways not necessarily tracking commitment and economic integration.  相似文献
