The recovery of identifiable fingerprints from fired cartridge cases is challenging. Therefore, the characterization of chemical modifications and their effects on fingerprint integrity post-firing is essential. In this study, the primary fingerprint lipids, including myristic acid, pentadecanoic acid, palmitoleic acid, palmitic acid, stearic acid, squalene, and cholesterol in fired and unfired cartridges, were extracted with acetonitrile, followed by derivatization using N,O-Bis(trimethylsilyl)trifluoroacetamide with 1% trimethylchlorosilane (BSTFA/1%TMCS). Squalane was used as the internal standard, and all quantifications were performed using gas chromatography coupled with mass spectrometry using a triple-quadrupole mass filter. All lipids identified in the unfired cartridges were also detected in the fired cartridges, and statistical analysis using Student's t-test and F tests was performed with a 95% confidence level. The concentration of lipids in the unfired cartridges was found to be similar to that detected in the fired cartridges, except for squalene, the recovery of which was 28% lower in the fired cartridges. 相似文献

Purpose
Psychopathy and psychopathic personality traits (PPT) have been linked to a long list of negative life outcomes. To date, however, few studies have provided a systematic analysis of whether psychopathic personality traits contribute to increased health burden. The current study was designed to address this gap in the literature.Method
This study analyzed data from the National Longitudinal Study of Adolescent Health and employed a measure of PPT derived from the five-factor model of personality. Analyses were conducted using OLS, logistic, and Poisson regression techniques.Results
The results revealed that relatively higher scores on psychopathic personality traits were associated with a slight increase in a wide range of negative health outcomes. These significant associations were detected for both males and females.Conclusions
We speak to the importance of these findings for the potential to reduce health burden among psychopaths and those who score relatively high on measures of psychopathic personality traits. 相似文献84.
This article aims to examine how the evaluation of party leaders’ traits influences voting behaviour. The work incorporates data from election studies across seven countries with different social contexts (Portugal, Spain, Ireland, Germany, United Kingdom, Italy and Hungary). Characteristics of leaders were placed into two groups: competence and warmth, in accordance with the stereotype content model and relevant studies on evaluations of leaders’ traits. Since different personality traits were evaluated within each country, the analysis was based on the two aforementioned dimensions and the political ideology of the leader. Multiple sequential binary logistic regression models were performed to analyse the predictive power of competence and warmth on voting behaviour, controlling for socio-demographic and political ideology variables of voters. Results reinforce the personalisation of politics theory, showing the relevance of leaders’ warm personality traits. As for the competence dimension, it was proven to be decisive only with regard to left-wing party leaders. 相似文献

Paraguay is often described as a territory of drug trafficking, smuggling and commercial piracy. However, the country remains understudied by academics researching criminality and illegal markets. Pedro Juan Caballero, a city located on the northern border with Brazil, is an interesting case study to illustrate how legality and illegality merge in Paraguay to create hybrid social orders. The daily life in the city, one of the best places in the world for cultivating marijuana, unfolds between the higher homicides rates and some of the lowest levels of common criminality in Paraguay. Far from being a matter of state weakness, the expansion and tolerance of illegal activities is framed within a cluster of order that combines both rational legal practices and neo-patrimonial norms. The presence and roles of state institutions are re-signified, generating alternative hierarchies, practices and values to supply social, political and economic outcomes. Through in-depth interviews with key informants, ethnography visits and analyses of aggregated data, this paper describes the hybrid order of Pedro Juan Caballero by tallying the incentives that encourage social and institutional tolerance of illegality and describes how illegal practices create access to goods, services, protection and expectations not provided by the legal framework. 相似文献

The study part of the proposed constitutional foundations laid in the model of the democratic rule of law, guided by convictions more human and sympathetic, in contrast to previous models carved under the aegis of dissociated financial aspirations of the relevance of a social growth. Among the arguments contained in the Constitution, it becomes two faces of freedom of expression —freedom of the press and the right to information— both in order to corroborate the importance of these values within a democratic society. Moreover, focusing on virtual relationships, we seek to understand what the decision-making positions in Brazil, in relation to press freedoms and the right to information. Finally, mention was made that there is the seat of the two main national courts (Supreme Court and Superior Court of Justice), negative bias over the Internet, going on, but the actual implementation of communicative freedoms, individual cases interpreting the light of constitutional prism and nuances that requires the digital environment, as a new reality in which human relationships are given. 相似文献

Self‐embedding behavior (SEB) is the repeated insertion of sharp objects, such as needles or pins, into the soft tissues of abdomen, limbs, and other body parts. In this study, two cases of SEB were reported and the scientific worldwide literature reviewed. Thirty‐two cases of SEB were identified through systematic searches in the main bibliographic databases. Mean age was 35 years (SD = 8.97). Just over two‐thirds of the patients were female. Although the number of embedded objects could be as high as 200, major clinical and surgical complications were uncommon and mortality was null. Patients with SEB presented three major diagnoses: psychotic (25%), personality (21.9%), and factitious (28.1%) disorders. The practice of SEB largely went undetected as the patients themselves did not bring it to the attention of family members or physicians and usually denied they have engaged in SEB. A high level of suspicion is required to avoid a missed diagnosis. 相似文献

Allele frequencies for 15 short tandem repeats (STR) loci were determined with a sample of 3000 unrelated individuals from the population of Santa Catarina, Southern Brazil. The loci are most commonly used in forensic and paternity testing, being analyzed by the Powerplex 16 (Promega) commercial kit. The data shows that most polymorphic loci were Penta E and FGA. The distributions of the genotypes in the evaluated loci are in Hardy–Weinberg equilibrium. Comparative analyses between our population data and other Brazilian populations are presented. The calculated forensic parameters showed that the loci are useful for the solution of forensic problems in Brazilian Southern region. 相似文献

At the Medical Legal Center in Ribeirão Preto, Brazil (CEMEL/FMRP-USP), unidentified decomposing bodies routinely undergo soft tissue removal (by immersion in water at 80–90 °C for 24 h) prior to an anthropological analysis intended to yield a biological profile of age, sex, ancestry, height, pathology and so on. In the event that this analysis is unsuccessful, samples may be submitted for DNA profiling. The tropical climate and the defleshing process may confound preservation, recovery and analysis of DNA, however. In order to establish an optimal standardized protocol for identification of decomposing human remains from a tropical climatic region, the outcome of anthropological and genetic analyses was compared, along with the utility of bone (mainly femur and sternum) and teeth (mainly molar) specimens for DNA analysis. In a sample (n = 39) of partially skeletonized remains, anthropological analysis was sufficient for identification in eight cases. In further six cases, DNA profiling was successfully attempted. As a consequence of our study, we recommend collection of 1–2 well preserved teeth prior to defleshing and anthropological analysis in these circumstances. 相似文献

High‐Resolution Melting (HRM) of Hypervariable Mitochondrial DNA Regions for Forensic Science 下载免费PDF全文
Alípio dos Santos Rocha M.Sc. Isis Salviano Soares de Amorim M.Sc. Tatiana de Almeida Simão Ph.D. Adenilson de Souza da Fonseca Ph.D. Rodrigo Grazinoli Garrido Ph.D. Andre Luiz Mencalha Ph.D. 《Journal of forensic sciences》2018,63(2):536-540
Forensic strategies commonly are proceeding by analysis of short tandem repeats (STRs); however, new additional strategies have been proposed for forensic science. Thus, this article standardized the high‐resolution melting (HRM) of DNA for forensic analyzes. For HRM, mitochondrial DNA (mtDNA) from eight individuals were extracted from mucosa swabs by DNAzol reagent, samples were amplified by PCR and submitted to HRM analysis to identify differences in hypervariable (HV) regions I and II. To confirm HRM, all PCR products were DNA sequencing. The data suggest that is possible discriminate DNA from different samples by HRM curves. Also, uncommon dual‐dissociation was identified in a single PCR product, increasing HRM analyzes by evaluation of melting peaks. Thus, HRM is accurate and useful to screening small differences in HVI and HVII regions from mtDNA and increase the efficiency of laboratory routines based on forensic genetics. 相似文献
