The 15 AmpFlSTR Identifiler loci D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA were analyzed in a sample of 378 unrelated individuals from Mexico City, Mexico. Significant deviations from HW equilibrium in 14/15 STR loci alleles were not detected. The D18S51 locus had the highest power of discrimination (0.970). Genetic admixture estimations revealed a 69% of Amerindian, 26% of European and 5% of African contribution. Comparative analyses between Mexicans and other neighboring populations reveal significant differences in genetic diversity. Our results are important for future comparative genetic studies in different Latin American ethnic groups, particularly Mexican Mestizos and Amerindians. They should also be helpful in genetics, population evolution, forensic and paternity testing. 相似文献

Lara Maria Herrera M.Sc. Raíssa Ananda Paim Strapasson M.Sc. Alice Aquino Zanin D.D.S. Jorge Vicente Lopes da Silva Ph.D. Rodolfo Francisco Haltenhoff Melani Ph.D. 《Journal of forensic sciences》2017,62(5):1279-1285
This study verified the difference between two methods of forensic facial approximation (FFA) regarding recognition and resemblance rates. Three‐dimensional models of skulls were obtained from computerized tomography (CT) scans of two subjects (targets). Two manual FFAs were performed for each target, by applying two different guidelines for the facial structures (what we called “American method” (AM) and “Combined method” (CM)). Unfamiliar assessors evaluated the sculptures by recognition and resemblance tests. The AM was that which allowed more correct responses of recognition and higher resemblance's scores for the male target (p < 0.001). Regarding guidelines for modeling characteristics of the face, the ones that are practical and easily performed for sculptures, such as the length of the anterior nasal spine multiplied by 3 for nose prediction, may offer better results in terms of resemblance. 相似文献

Stealing thunder refers to a dissuasion tactic in which an individual reveals potentially incriminating evidence first, for the purpose of reducing its negative impact on an evaluative audience. We examined whether it was necessary to frame the negative revelation in a manner that downplayed its importance, and found that stealing thunder successfully dissuaded mock jurors even without framing. We also sought to determine the mechanism by which stealing thunder operated, and found that stealing thunder led mock jurors to change the meaning of incriminating evidence to be less damaging to the individual. We also found that stealing thunder's effectiveness did not hinge on whether or not opposing counsel also mentioned the thunder evidence, and that the stealing thunder tactic was no longer effective when opposing counsel revealed to the mock jurors that the stealing thunder tactic had been used on them. 相似文献

Many terrorist factions care about the level of popular support they enjoy within a population they claim to represent. Empirically, this level of support can either rise or fall in the aftermath of a campaign of terrorist violence. Under what circumstances is the use of terror an effective tactic for mobilizing political support for an extremist group? This article models a scenario in which an extremist faction considers attacking a government in the hopes of provoking a counterterror response that will radicalize the population, increasing the extremists' support at the expense of a more moderate faction. In our scenario, such radicalization can result either from the economic damage caused by counterterror operations or by the way in which such operations change the population's assessment of the government's motivations. We demonstrate that such attempts at mobilizing public support can be, but need not be, successful, discuss factors that make both the initiation of a terror campaign and successful mobilization more or less likely, and relate our results to several empirical cases. 相似文献

This study examined the cultural and developmental significance of maternal and paternal parenting processes (closeness, support, monitoring, communication, conflict, and peer approval) for measures of anxiety and depression symptoms in adolescents from Hungary, the Netherlands, Switzerland, and the United States (N=6,935). Across all cultural contexts, measures of maternal and paternal support and conflict were most consistently associated with measures of internalizing behaviors. Few differences were observed in the importance of individual parenting processes for anxiety or depression symptoms across cultures. Additionally, with the exception of maternal conflict for anxiety and depression symptoms and paternal closeness for depression symptoms, none of the parenting process dimensions differed in importance for internalizing behaviors across developmental periods (middle versus late adolescence). The investigation provides evidence of great similarity in developmental processes, both across cultural contexts and developmental periods.

Population frequencies for the 9 Y-STR loci included in the "minimal haplotype" from Y-STR Haplotype Reference Database (YHRD), plus other 6 Y-STRs (DYS437, DYS438, DYS439, GATA A7.2, GATA H4 and GATA A10) were obtained for a sample of 120 males from Quito (Ecuador). One hundred and sixteen unique haplotypes were identified within the sample. Haplotype diversity (0.9994) was among the highest in comparison to other populations from Iberia and South-America. Genetic distances were calculated and our sample presented significative differences with all other samples, the lowest values being with a Guinean sample. 相似文献

This article offers an examination of the official rules that participate in the organization of street vending activities in Latin American cities. It does so by explaining the legal assemblages that serve to define how, where, and by whom certain Latin American public spaces may be occupied, and by empirically illustrating the way in which the legal status of street vendors—that is, whether or not they are willing or able to get official recognition to work in these public spaces—affects the way they use and occupy the urban landscape. The information gathered here suggests that securing access to official permission to work on the streets does significantly affect vendors' locations as well as their working modalities. The subsequent analysis also illustrates a significant relationship between vendors' legal status and specific interactions with urban authorities and other actors. These findings suggest that, although law cannot prevent the unauthorized occupation of public spaces for commercial purposes, it could certainty avert the reproduction of other illegal practices and, perhaps most importantly, protect the urban poor from the vulnerability they face before state and nonstate violence. 相似文献

This article assesses the effect of changes in the lawmaking process on the success of the president’s legislative agenda, distinguishing between within-term success (bills that passed during the term) and overall success (including bills that passed after the president left office). With the 2064 presidential bills introduced in seven terms (1990–2018) in Chile’s presidential system, we assess the impact of changes in lawmaking rules on within-term (59.9%) and overall success (70.6%). Changes that decrease attributions of the president and create more opportunities for executive-legislative bargaining—including concurrent elections—increase the chances of success of presidential bills. The use of presidential urgency motions, an agenda-setting tool, makes bills more likely to pass, but the issuance of many urgency motions undermines the bill’s chances to succeed. Presidential bills introduced early in the term and those on issues where there is more policy convergence are more likely to pass. 相似文献
