Identification from video surveillance systems is frequently requested in forensic practice. The "3D-2D" comparison has proven to be reliable in assessing identification but still requires standardization; this study concerns the validation of the 3D-2D profile comparison. The 3D models of the faces of five individuals were compared with photographs from the same subjects as well as from another 45 individuals. The difference in area and distance between maxima (glabella, tip of nose, fore point of upper and lower lips, pogonion) and minima points (selion, subnasale, stomion, suprapogonion) were measured. The highest difference in area between the 3D model and the 2D image was between 43 and 133 mm(2) in the five matches, always greater than 157 mm(2) in mismatches; the mean distance between the points was greater than 1.96 mm in mismatches, <1.9 mm in five matches (p < 0.05). These results indicate that this difference in areas may point toward a manner of distinguishing "correct" from "incorrect" matches. 相似文献

This study re-examined the role of romantic relationship characteristics in unwanted pursuit behavior (UPB) perpetration. Relationship characteristics were investigated accounting for the role of breakup characteristics using data from 396 divorced adults and advanced count regressions. The main effects of former relationship characteristics (except conflict) did not contribute explained variance to the frequency of UPBs when controlling for significant breakup characteristics (initiator status and post-breakup negative affect). However, moderator analyses revealed significant effects of relationship satisfaction, alternatives, investments, and anxious attachment in interaction with initiator status and of relationship alternatives in interaction with post-breakup negative affect. These findings illustrate that the association between relationship characteristics and UPB perpetration is more complex than previously thought and are theoretically and clinically valuable. 相似文献

The introduction of electronic systems into the comparison of weapon marks in the mid 1990s caused a revolution in the discipline of “forensic ballistics”. Most European states now use this technology to search their national open case files.Globalisation of crime and the loss of effective border controls have made the idea of a unified European ballistic system seem logical.The article critically considers the requirements and possible outcomes of such a system. Based on the experience of forensic practitioners it seems probable that a shared European electronic ballistic system will be of a very limited value at present. Further improvements of existing systems to reach compatibility are encouraged. 相似文献

Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Since 2004, in order to examine patterns of secondary dentine apposition, Cameriere et al. have been extensively studying the pulp/tooth area ratio of the canines by panoramic and peri-apical X-ray images. The main aim of this paper is to examine the relationship between age and age-related changes in the pulp/tooth area ratio in monoradicular teeth, with the exception of canines, by orthopantomography. A total of 606 orthopantomograms of Spanish white Caucasian patients (289 women and 317 men), aged between 18 and 75 years and coming from Bilbao and Granada (Spain), was analysed. Regression analysis of age of monoradicular teeth indicated that the lower premolars were the most closely correlated with age. An ANCOVA did not show significant differences between men and women. Multiple regression analysis, with age as dependent variable and pulp/tooth area ratio as predictor, yielded several formulae. R(2) ranged from 0.69 to 0.75 for a single lower premolar tooth and from 0.79 to 0.86 for multiple lower premolar teeth. Depending on the available number of premolar teeth, the mean of the absolute values of residual standard error, at 95% confidence interval, ranged between 4.34 and 6.02 years, showing that the pulp/tooth area ratio is a useful variable for assessing age with reasonable accuracy. 相似文献

Abstract: Supine hypotensive syndrome is characterized by severe supine hypotension in late pregnancy, whose clinical presentation ranges from minimal cardiovascular alterations to severe shock, resulting from inferior vena cava compression by gravid uterus. We report a case of a 41‐year‐old 39‐week‐pregnant woman found dead supine. Autopsy revealed the following: cyanosis of the limbs; congestion of the jugular and subclavian veins; abundant abdominal subcutaneous fatty tissue; uterus displacing intestine and diaphragm; collapsed inferior vena cava; both femoral veins dilated and filled with blood; edematous and congested lungs; and placenta 790 g, fetus 3475 g, amniotic fluid 800 cm3. The diagnosis of supine hypotensive syndrome as the probable cause of death is supported by the position of the body and autopsy findings. This syndrome can be considered as the first stage of the physio‐pathological mechanism that led to death in the case presented herein and should be considered by pathologists as a cause of sudden death. 相似文献

This article describes the autopsy findings of a victim of a shark attack that took place off the coast of Pernambuco, Brazil. The victim was rescued and immediately taken to a nearby hospital but did not survive, even though the lapse of time between the attack and verification of death did not exceed 15 minutes. The presence of a single, large, contused and incised, semiarched wound with a serrated aspect was decisive in elucidating the event. Thus, this study discusses aspects related to the aggressor species, to the autopsy, to the type of wound, and to the causes that have led to a significant increase in this type of event in the area. It was concluded that the lesion was produced while the victim was still alive and that it was the cause of death. 相似文献

Published to coincide with the quincentennial celebrations of Columbus's ‘discovery’ of the New World, the Native American writer Leslie Marmon Silko's apocalyptic 1991 novel, Almanac of the Dead, is a harsh indictment of five hundred years of colonialism, racism and genocide in the New World. Silko clearly links this inhuman(e) history to the contemporary social policies of a range of nation states within the Americas, to present a variety of political issues that are of crucial significance to contemporary tribal communities and other multi-national disenfranchised groups. Among others, this includes the significance of gender to constructions of American settlement and Federal-Indian relations, and to Silko's own status, and choice of literary topics, as a female (and Native) writer. This essay analyses Silko's disruption of authorized and sanitized state narratives, and of accepted (and acceptable) narratives of settlement; and considers Silko's use of the almanac form – the codex – of the pre-contact Aztec and Mayan libraries as a means to assert indigenous literacy, and to challenge the Euro-American claims to ‘civilization’ that are the basis for New World settlement. Most significantly, as its title suggests, Almanac of the Dead emphasizes the presence of the dead, both indigenous peoples and African slaves, to expose the real costs of settlement, and to actively un-settle the Euro-American reader. Consequently, Almanac of the Dead presents the powerful alternative histories of a range of dispossessed social and ethnic groups throughout the Americas, while relocating and reconsidering the US within the context of the Americas as a continental and historical whole, and emphasizing the positive potential of political activism. 相似文献

One hundred and fifty individuals have been sampled across Central-South Italy and genotyped for Y chromosome STRs by PowerPlex Y system. Comparison with previous Italian databases revealed that majority of Y chromosome variation still need to be sampled. Identification of locus duplications, distribution of genetic variation and firstly identified alleles point to the necessity of more focused sampling strategies for reference databases. 相似文献

The present study analyses three tetranucleotide (DXS7423, DXS8378, DXS6809) and one trinucleotide (DXS7424) X-linked STRs loci in a population sample of North Italy to evaluate their efficiency in forensic applications. The four loci were also used to solve a case of deficiency paternity, in which the question was to establish whether two women were half sisters. 相似文献
