Over the last twenty years, Brazil has staked successive claims to regional leadership, with varying explicitness and unclear success. What factors explain the acceptance or rejection of such claims by South American countries? This article summarises the literature on regional powers and frames regional powerhood as arising from geographical belonging, resources, and will to lead; and leadership/followership as stemming from exclusivity, hierarchy/influence, consensus, and provision. By analysing panel data on Brazil and South America from 1995 to 2015, the study concludes that Brasilia enjoyed higher followership in situations characterised by high exclusivity and consensus, and low hierarchy and provision. These conditions were present in South America in the 1990s, thus rendering that decade more receptive to Brazilian leadership.  相似文献

There have been many methods proposed to estimate the age of human bones in forensic medicine or in forensic anthropology, including those that assess histological structures. In this study, age was evaluated through the histomorphometric study of trabecular volume and cortical width of the right iliac crest. A total of 25 samples A total of 66 samples (42 male and 24 female) were obtained from necropsies of judicial cases, with ages ranging from 13 to 58years, who had died a sudden or violent death. The samples were obtained using Bordier's trocar for bone biopsy, in a period not exceeding 24h after death. The samples were examined without decalcification, with 96° alcohol dehydration, embedding in methyl methacrylate, and sectioned with a microtome Reichert (3μm). The sections were fixed on microscope slides and stained using toluidine blue, Goldner trichrome and hematoxylin-eosin methods. The samples were studied under a Leica DM LB microscope and the images were digitally captured. The digital images were processed using an image analysis program and data were analyzed using the SPSS statistical package. The results demonstrated that the combination of the trabecular volume and cortical width acted as predictors of the age in subjects which did not suffer from any deterioration of bone and/or mineral metabolism.  相似文献

Abstract: Arthropods at different stages of development collected from human remains in an advanced stage of decomposition (following autopsy) and from the soil at the scene are reported. The corpse was found in a mixed deciduous forest of Biscay (northern Spain). Soil fauna was extracted by sieving the soil where the corpse lay and placing the remains in Berlese–Tullgren funnels. Necrophagous fauna on the human remains was dominated by the fly Piophilidae: Stearibia nigriceps (Meigen, 1826), mites Ascidae: Proctolaelaps epuraeae (Hirschmann, 1963), Laelapidae: Hypoaspis (Gaeolaelaps) aculeifer (Canestrini, 1884), and the beetle Cleridae: Necrobia rufipes (de Geer, 1775). We confirm the importance of edaphic fauna, especially if the deceased is discovered in natural environs. Related fauna may remain for days after corpse removal and reveal information related to the circumstances of death. The species Nitidulidae: Omosita depressa (Linnaeus, 1758), Acaridae: Sancassania berlesei (Michael, 1903), Ascidae: Zerconopsis remiger (Kramer, 1876) and P. epuraeae, Urodinychidae: Uroobovella pulchella (Berlese, 1904), and Macrochelidae: Glyptholaspis americana (Berlese, 1888) were recorded for the first time in the Iberian Peninsula.  相似文献

Intimate partner violence (IPV) is a serious, preventable public health problem. IPV perpetration is strongly associated with Anxiety disorders at the population level. We investigated whether the association could be explained by coexisting psychiatric conditions or Borderline personality traits, using a combined data-set of two National Household Surveys (n = 15,973). Results showed women were more likely to report perpetrating IPV than men. Anxiety disorders were associated with IPV. When coexisting psychiatric conditions together with a categorical diagnosis of Borderline Personality Disorder (BPD) were investigated as explanatory variables, 19.2% of the association between Anxiety disorders and IPV was explained. Using individual Borderline traits in place of a categorical diagnosis of BPD, 58.3% of the association was explained. In conclusion, the association between Anxiety disorders and IPV was partly, but not fully, explained by coexisting psychiatric conditions and individual Borderline traits. Perpetrators of IPV should be screened for Anxiety disorders and among those with Anxiety disorders, Borderline traits are important.  相似文献

Asphyxial deaths are common in forensic practice, being sustained by a variety of mechanisms that cause an oxygen deficiency to the brain. Several classification models have been proposed in the literature, the most recent one being that of the International Network for Forensic Research Group (INFOR). This report describes an unusual case of suffocation where the obstruction of the airways was caused by a gag formed of three latex gloves and a handkerchief. The manner of death (differential diagnosis between homicide and suicide) and the different alternatives of classification are discussed.  相似文献

Bullying in secondary schools is a serious concern for educators and parents. The relationship between bullying and school climate has been identified and strategies to improve school climate are available. The importance of leadership in shaping school climate has been well documented. This exploratory study explores the role of leadership in implementing an approach to school climate change (positive behavior intervention and supports) in comprehensive Southwestern high schools participating in a federal school safety grant. Leadership involvement in the change process appears to be a key component leading to student-reported behavior change. Our findings suggest that although changes in school climate should lead to changes in bullying behaviors, the opposite is the case. Implications for practice and further research are discussed.  相似文献

The content of ecstasy tablets has been changing over the years, and nowadays 3,4‐methylenedioxymethamphetamine (MDMA) is not always present in the tablets. The aim of this study was to investigate the chemical composition in the seized tablets labeled as ecstasy. We analyzed samples from 150 different seizures made by Sao Paulo's State Police by gas chromatography–mass spectrometry. MDMA was present in 44.7% of the analyzed samples, and another twenty different active substances were identified in these tablets, such as caffeine, 2C‐B, piperazines, amphetamines, phencyclidine, and others. Methamphetamine was present in 22% of these samples. The results demonstrate a huge shift in the pattern of trafficking of synthetic drugs, where MDMA has been replaced in tablets mostly by illicit psychoactive substances, in a clear attempt to bypass the law. The great variability in the tablets composition may lead to an increased risk of drug poisoning.  相似文献
