The adoption of the Treaty of Lisbon and the granting to the Charter of Fundamental Rights of the same legal force as the Treaty has lent a new impulse to the consideration of fundamental human rights by the European Union (EU). The question remains, however, as to how this legal discourse, centred upon human rights, is actually shaping the EU regulatory framework in specific policy domains. The aim of this paper is to critically appraise the ways that the fundamental rights of security, privacy and freedom guaranteed by the Charter are being construed in the context of EU law and policy on biometrics, an ethically and morally sensitive security technology whose development and use are being actively promoted by the EU. We conclude that the interpretation of the pertinent rights, as well as their balancing, owes a great deal to the goals of EU policies for research and development, and under the auspices of Freedom, Security and Justice, shaped largely by political and economic considerations. These considerations then tend to prevail over ethically or morally-based legal claims.  相似文献

Palatal rugae have been related with specific racial groups and are said to be useful in sex discrimination. This work aimed to characterize the palatal rugae patterns in a Portuguese population. Fifty plaster casts were examined for first and third rugae shape evaluation; shape, frequency, and association with sex were studied. In females, the most prevalent first rugae were the straight type on the right and the curve type on the left; in males, the straight type was the most prevalent on both sides. The most frequent third rugae type was sinuous on both sides, in both sexes. No significant sexual dimorphism in rugae shape was found (p > 0.05). When comparing these results with those from other investigations, it was clear that a particular rugae pattern could be established for different ethnic groups. However, the small sample size justifies further work in larger samples to validate these findings.  相似文献

Acute promyelocytic leukemia (APL) is a subtype of acute myelogenous leukemia frequently associated with clotting abnormalities and severe hemorrhagic diathesis. The disease is associated with a high incidence of early fatal hemorrhage. We report the sudden death of a 40-year-old male without significant medical history in which foul play had been initially suspected. A thorough postmortem investigation performed on the decedent lead to the diagnosis of APL. Cause of death was a cerebellar hematoma. Underlying APL should be considered in the differential diagnosis when unexplained bleeding is encountered in a decedent. This case emphasizes the value of routinely collecting bone marrow during an autopsy to enable accurate testing and diagnosis.  相似文献

Vertebral artery removing constitutes a significant forensic pathology challenge. Dissection techniques during head-neck autopsy are based on anterior approach, a difficult method, which is unable to assess the transverse part of the artery. This work presents an original and simple method for dissecting vertebral arteries by a posterior approach, opening the vertebroarterial canal through the spinal canal without any special equipment. Once the spinal cord is removed, the transversarium foramens are opened by an internal cut at the pedicle and an external cut at the transverse process. This enables us to visualize vertebral arteries in its entirety. The method improves both the examination of the upper extracranial segment of the vertebral artery and the neuropathological study when arterial injury is suspected. Applying this method routinely is both feasible and useful in suspected cases of vertebral artery trauma and could contribute to assess more precisely the actual incidence of this injury.  相似文献

Is there such a thing as “Asian sexuality”? Do Asians approach sex in particular ways that are uniquely cultural? Some “Eastern” sex manuals published in English cover the “tao” and tantric philosophies of sex, highlighting the pleasures of Asian styles. Yet, any discourse on “Asian sexuality” must be an orientalist one that pits the West versus the East (Asian). In Singapore, there is an official discourse of sexuality that similarly essentializes West versus East (Asian), and this discourse has long served as the rationale or alibi for repressive sexual policies. In particular, these official constructions make “Asians” as sexually conservative. This essay deconstructs the meaning of “Asian sexuality” as used in the Singapore context and shows the contradictions inherent in official policies that adopt Western colonial laws to proscribe certain sexual practices—albeit in the name of “Asian values”.  相似文献

Dust was investigated for its ability to retain source attribution profiles (SAPs) after chemical exposure. Three distinct sources of the organophosphate pesticide acephate were investigated as a proof-of-concept model. In addition, attribution profiles were created and tested using compounds related to chemical warfare agents (CWAs), specifically VX and G-series agents: O-ethyl methylphosphonothioate (EMPTA), N,N-diisopropylmethylamine (DIPMA), N,N-diisopropylethylamine (DIEA), diisopropylamine (DIPA), diethyl aniline (DEA), diethyl ethyl phosphonate (DEEP), trimethyl phosphite (TMP), dimethyl hydrogen phosphite (DMHP), diethyl hydrogen phosphite (DEHP), triethyl phosphate (TEP), ethyl methylphosphonate (EMPA), and diisopropyl methylphosphonate (DIMP). Dust was collected from a storage shed, aliquots deposited on carpet and loaded with distinct chemical profiles using an exposure chamber and aerosolizer. After a given period of time (1h, 24h, or 72 h), the dust was extracted and its SAP analyzed by gas chromatography-mass spectrometry (GC-MS) and/or liquid chromatography-tandem mass spectrometry (LC-MS/MS). Principal components analysis (PCA) was used to determine the association of dust exposed to the same and different chemical sources. PCA results demonstrate that dust samples exposed to distinct chemical sources are clearly differentiated from one another across all collection times. Furthermore, dust aliquots exposed to the same source can be clearly associated with one another across all collection times. When the CWA-related compounds were subjected to elevated temperature (90°C) conditions, it was found that the signature was stable at the 1h and 24h collections. At 72 h and elevated temperature, larger deviations from the control were observed for some compounds. Elevated pH (10) affected the profile to a lesser degree than elevated temperature. Overall, dust is found to be an effective media for the in situ collection of source attribution profiles.  相似文献

Traumatic vertebral artery dissection is not often seen by forensic pathologists, and cases investigated are scarce in the forensic literature. We present the case of a 40-year-old woman cyclist who was struck by a car while wearing a helmet, and was neurologically near normal immediately thereafter at Emergency. She presented 48 h later with acute right hemiparesis, decreasing level of consciousness, and unsteadiness. CT revealed massive cerebellar infarction. CT angiography was normal. The patient died in coma 7 days after injury and autopsy revealed bilateral edematous cerebellar infarction and bilateral vertebral artery dissection. Rotational neck injury and mural tear in the wall of the Atlantic parts of both vertebral arteries is suggested as the possible mechanism of the arterial injury. Head and neck injuries are reported as a precipitating cause of vertebral artery injury. The possible influence of trauma may be further underestimated if longer intervals between vessel dissection and ischemia occur. The current case illustrates that "talk-and-die" syndrome may be due to occult vertebral artery dissection, possibly bilateral. In forensic cases of delayed death after mild trauma to the head and neck, the vertebral arteries should be examined for the cause of death.  相似文献

Acts of violence recounted by 161 female victims of Intimate Partner Violence (IPV) attended at a psychological care service in Spain are presented. The relationship between acts of violence and feelings of danger, childhood abuse, and dyadic adjustment are analyzed. Reported acts of IPV were obtained through a Semi-structured Interview on Domestic Violence; and marital satisfaction was assessed with the Dyadic Adjustment Scale. The results showed women who have felt their lives were in danger are more likely to have been victimized. In addition, women who were both abused by their partner and sexually abuse as children are the ones that perceive more situations of danger in their adult couple relationship. The importance of studying perceived danger and the diversity of IPV experiences are discussed to aid prevention and intervention strategies.  相似文献

We analysed the Chilean university student selection processes, comparing ‘First Generation’ and ‘Continuist’ students, using the Chilean Higher Education population databases (2000–2015). Findings confirm that 60 percent of participants in the selection process are First Generation students. The data registers an increasing self-exclusion phenomenon. Of the students who did not take the selection test after enrolling, 80 percent are First Generation and 18 are enrolled in a selective university, compared to 44 in the Continuist conglomerate. These differences may be explained by cultural capital in the Bourdieu sense, in conjunction with a diversified, massified and marketalised higher education system.  相似文献
