It is impossible to understand the gendered relation between women and public space without taking into account its other, that is, male engagements with and in space. Our joint paper contrasts the public spaces of a market and a bus station in central Accra, Ghana. While the former is historically associated with female entrepreneurship, masculinity is deeply inscribed in the activities defining the latter. However, recent developments gradually undermine these gendered divides. By focusing on interpersonal claims to entrepreneurial places in the two locations, we illustrate how the configurations and co-constructions of gender and space are exposed to on-going, often subtle shifts, which are impelled by dialectically grounded transformations of quotidian spatial practices and social relations. Expanding upon the notion of viri–/uxorilocality, we explore shifts in the gendered strategies of newcomers establishing their presence in the two spaces and the extent to which these practices may alter gendered spatial significations.  相似文献

A fully validated, sensitive and specific method for the extraction and quantification of Δ9-tetrahydrocannabinol (THC) and 11-nor-9-carboxy-Δ9-THC (THC-COOH) and for the detection of 11-hydroxy-Δ9-THC (11-OH THC) in oral fluid, urine and whole blood is presented. Solid-phase extraction and liquid chromatography–mass spectrometry (LC–MS) technique were used, with electrospray ionization. Three ions were monitored for THC and THC-COOH and two for 11-OH THC. The compounds were quantified by selected ion recording of m/z 315.31, 329.18 and 343.16 for THC, 11-OH THC and THC-COOH, respectively, and m/z 318.27 and 346.26 for the deuterated internal standards, THC-d3 and THC-COOH-d3, respectively. The method proved to be precise for THC and THC-COOH both in terms of intra-day and inter-day analysis, with intra-day coefficients of variation (CV) less than 6.3, 6.6 and 6.5% for THC in saliva, urine and blood, respectively, and 6.8 and 7.7% for THC-COOH in urine and blood, respectively. Day-to-day CVs were less than 3.5, 4.9 and 11.3% for THC in saliva, urine and blood, respectively, and 6.2 and 6.4% for THC-COOH in urine and blood, respectively. Limits of detection (LOD) were 2 ng/mL for THC in oral fluid and 0.5 ng/mL for THC and THC-COOH and 20 ng/mL for 11-OH THC, in urine and blood. Calibration curves showed a linear relationship for THC and THC-COOH in all samples (r2 > 0.999) within the range investigated.The procedure presented here has high specificity, selectivity and sensitivity. It can be regarded as an alternative method to GC–MS for the confirmation of positive immunoassay test results, and can be used as a suitable analytical tool for the quantification of THC and THC-COOH in oral fluid, urine and/or blood samples.  相似文献

A European scholar explores the changing dynamics of integration processes within the Eurasian Customs/Economic Union in the new context created by the Ukraine crisis. The article examines positions adopted by member states Russia, Kazakhstan, and Belarus before and after onset of the crisis in Ukraine. Several rationales for justifying the Union are derived from international relations theory and documented in the rhetoric of actors from these three countries. The evolution of conflicting rhetorical postures mirrors a slowdown of the Eurasian integration process and growth in the bargaining leverage of Belarus and Kazakhstan vis-à-vis Moscow.  相似文献

Compression of the neck, either with the hands or by a ligature, is not an uncommon method of homicide. Burning of the body to try to conceal the homicide may complicate the situation by making it difficult to interpret the findings. We hereby report two cases of homicidal ligature strangulation with extensive burning of the bodies. In both cases, external findings included the presence of a soft piece of fabric around the neck that, when removed, disclosed a portion of pale, unburned skin that vividly contrasted with surrounding areas. Osteocartilaginous lesions were present in only one case. Carboxyhemoglobin levels in both cases were very low, and the histopathologic examination of distal airways for soot particles was negative.  相似文献

Bystanders in cyberaggression can support the victim, join the aggressor, or remain passive. We examined how supportive and passive adolescent Czech cyberbystanders (N = 443, ages 12–18) differ in terms of individual characteristics, emotional responses, and contextual factors. The most substantial distinguishing factor between the two groups turned out to be whether they had received a request to help the victim. After such a request, cyberbystanders supported the victim; moreover, most of those who had not been asked reported that they would have actively reacted to a request for help. The findings also showed the significant role of immediate empathic response, which increased the odds of support even after controlling for individual characteristics. The results are discussed with regard to prevention and intervention efforts.  相似文献

Clobazam (Castillium, Urbanil), a benzodiazepine often used as an anxiolytic and in the treatment of epilepsy, is considered a relatively safe drug. The authors present a fatal case with a 49-year-old female, found dead at home. She had been undergoing psychiatric treatment and was a chronic alcoholic. The autopsy findings were unremarkable, except for multivisceral congestion, steatosis and a small piece of a plastic blister pack in the stomach. Bronchopneumonia, bronchitis and bronchiolitis were also diagnosed. Anhigh-performance liquid chromatography (HPLC)/diode array detector (DAD)/mass spectrometry detection (MSD) with electrospray method was developed in order to detect, confirm and quantify clobazam in the post-mortem samples. In the chromatographic separation, a reversed-phase column C18 (2.1 x 150 mm, 3.5 microm) was used with a mobile phase of methanol and water, at a 0.25 ml/min flow rate. Carbonate buffer (pH 10.5) and 20 microl of prazepam (100 microg/ml) as internal standard were added to the samples. A simple and reliable liquid-liquid extraction method for the determination of clobazam in post-mortem samples was described. Calibration curves for clobazam were performed in blood, achieving linearity between 0.01 and 10 microg/ml and a detection limit of 1.0 ng/ml. The clobazam concentration found in post-mortem blood was 3.9 microg/ml, higher than the reported therapeutic concentration (0.1-0.4 microg/ml). The simultaneous acquisition by photodiode array detection and mass spectrometry detection results allowed benzodiazepines to be identified with sufficient certainty. An examination of all the available information suggested that death resulted from respiratory depression due to clobazam toxicity.  相似文献

Pesticides are used in most countries around the world to protect agricultural and horticultural crops against damage. Poisoning by these toxicant agents occurs as a result of misuse or accidental exposure, and also by oral ingestion (voluntary or not). In Portugal, pesticide intoxications are still a cause of death, found in a considerable number of cases. The authors retrospectively examined the cases of pesticide poisoning in the Centre of Portugal, from autopsies performed in the Forensic Pathology Service of Coimbra's Delegation of the National Institute of Legal Medicine (NILM) and from other autopsies carried out in the Centre of Portugal, as well as some samples taken in hospitals in cases of suspected intoxication. In this study, the positive cases have been especially studied, in order to identify the pesticide used, as well as the etiology. The frequency of intoxications and its distribution by sex and age were also analyzed. Between January 2000 and December 2002, the Forensic Toxicology Laboratory received 639 pesticide analysis requests. In 2000, in a total of 149 analysis requests, 30 cases were positive, 63.3% from male individuals and 36.7% from female. In 2001, the analysis requests increased to 240 as well as the positive cases (43), 74.4% from male individuals and 25.6% from female and in 2002, the total cases analyzed also increased to 250, with 38 positive (73.6% from male individuals and 26.4% from female). Among the pesticides, organophosphorus insecticides still constitute the most important class detected in forensic intoxications, representing 63% of the total positive cases, followed by herbicides, with 33% of the positive results. Quinalphos is the most important organophosphorus insecticide, present in 32 of the 111 positive cases, followed by the herbicide paraquat, detected in 31 cases. The study emphasizes the increasing number of pesticide analyses, particularly relevant for the organophosphorus compounds and herbicides. Intoxication suspicion, accidental or voluntary, seems to be the most common cause of the incidents, for which analyses are requested, but it is also evident that the putative cause is unknown in a large number of cases. Therefore, more stringent legislation and enforcement regarding the sale and distribution of these toxic substances are needed.  相似文献
