Decomposed bodies pose many questions for researchers regarding environmental effects, cause of death, and patterns. This study aimed to observe the factors associated with decomposed bodies autopsied at the Johannesburg Forensic Pathology Service Medico‐legal Mortuary. A total of 4876 autopsies were conducted from 2010 to 2011, of which 109 were decomposed. Black individuals made up the largest proportion (67%) followed by White (26%). Males comprised 86.2%, while 12.8% were female. The mean age was 42.78 years. Most cases were in the early stages of decomposition (49.5%), with 32.1% bloated, 11.9% in active decay, 2.8% in advanced decay, and 3.7% were skeletal. Insect activity was identified in 25.7% of decomposition cases. Cause of death was determined in 48.6% of cases. Of all the cases, 64% were found indoors and 23% outdoors, while 23% had insufficient information regarding the location. Of considerable interest was the number of cases from hospitals and clinics.  相似文献

A rapid and sensitive method using LC-MS/MS triple stage quadrupole for the determination of traces of amphetamine (AP), methamphetamine (MA), 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”), 3,4-methylenedioxyethamphetamine (MDEA), and N-methyl-1-(3,4-methylenedioxyphenyl)-2-butanamine (MBDB) in hair, blood and urine has been developed and validated. Chromatography was carried out on an Uptisphere ODB C18 5 μm, 2.1 mm × 150 mm column (Interchim, France) with a gradient of acetonitrile and formate 2 mM pH 3.0 buffer. Urine and blood were extracted with Toxitube A® (Varian, France). Segmented scalp hair was treated by incubation 15 min at 80 °C in NaOH 1 M before liquid–liquid extraction with hexane/ethyl acetate (2/1, v/v). The limits of quantification (LOQ) in blood and urine were at 0.1 ng/mL for all analytes. In hair, LOQ was <5 pg/mg for MA, MDMA, MDEA and MBDB, at 14.7 pg/mg for AP and 15.7 pg/mg for MDA. Calibration curves were linear in the range 0.1–50 ng/mL in blood and urine; in the range 5–500 pg/mg for MA, MDMA, MDEA and MBDB, and 20–500 pg/mg for AP and MDA. Inter-day precisions were <13% for all analytes in all matrices. Accuracy was <20% in blood and urine at 1 and 50 ng/mL and <10% in hair at 20 and 250 pg/mg. This method was applied to the determination of MDMA in a forensic case of single administration of ecstasy to a 16-year-old female without her knowledge during a party. She suffered from hyperactivity, sweating and agitation. A first sample of urine was collected a few hours after (T + 12 h) and tested positive to amphetamines by immunoassay by a clinical laboratory. Blood and urine were sampled for forensic purposes at day 8 (D + 8) and scalp hair at day 60 (D + 60). No MDMA was detected in blood, but urine and hair were tested positive, respectively at 0.42 ng/mL and at 22 pg/mg in hair only in the segment corresponding to the period of the offence, while no MDA was detectable. This method allows the detection of MDMA up to 8 days in urine after single intake.  相似文献

The deposition of methamphetamine within indoor environments due to illegal activities can pose a health risk for occupants. Current cleaning techniques are costly and inefficient, calling for the development of alternative remediation methods. In addition, the fate of methamphetamine in indoor environments is largely unknown, negatively impacting our knowledge on the health risks associated with contaminated dwellings. Under the conditions of this study, 97% of surface deposited methamphetamine on a paper substrate was consumed after 12 min of exposure to ozone, thus demonstrating potential for its use as a remediation agent. The reaction had an effective second‐order rate constant with an upper limit of 2.15 ± 1 × 10?18 cm3/molecule/s, and the main product observed was phenyl‐2‐propanone (P2P) at 8.3% yield, as determined using GC/MS. Several products observed in this study have also been reported as by‐products of methamphetamine synthesis, including P2P—a known methamphetamine precursor, which indicates that their detection at a potential clandestine site is not necessarily evidence of manufacture.  相似文献

Telephone town halls are an increasingly prevalent method for members of Congress (MCs) to communicate with constituents, even while garnering popular criticism for failing to facilitate engagement and accountability. Yet scholars have paid little attention to the events and their effects, and even less to how they might be improved. To remedy this problem, we report on a field experiment in which four MCs joined their constituents in telephone town halls. Overall, participation in an event improved constituents’ evaluations of the format in general, and of the MC in particular. Furthermore, we studied how these events might be improved by evaluating a reform—a single‐topic focus with predistributed briefing materials—designed to enhance deliberative interaction. This reform enhanced effects on opinions of the format without significantly altering effects on attitudes toward the MC. Our results suggest that telephone town halls hold promise for constituents, officeholders, and democratic practice.  相似文献

Abstract

Mothers in prison separated from their young children are an overlooked group. Attachment theory could provide a useful model to underpin interventions and better support women affected by separation from their infants. Current policy draws on a limited body of evidence and research has developed considerably since its first design. This review systematically searched all relevant UK prison policy and government documents with regards to mother and child separation in prison and analysed the extent to which these documents draw on attachment theory. Following initial searches, 58 documents were thematically analysed. Attachment was implicitly referred to in most documents but only explicitly mentioned in four. Global themes identified included ‘separation as trauma’. However, document groups varied in focusing either on the mother or the child and there were no joint perspectives. Developing and researching specific attachment-informed interventions might be one way forward as would further attachment-based research in this area.  相似文献

Research has documented a negative relationship between religion and risky sexual behavior. Few studies, however, have examined the processes whereby religion exerts this effect. The present study develops and tests a model of various mechanisms whereby parental religiosity reduces the likelihood of adolescents’ participation in risky sexual behavior (early sexual debut, multiple sexual partners, and inconsistent condom use). Structural equation modeling, using longitudinal data from a sample of 612 African American adolescents (55% female), provided support for the model. The results indicated that parental religiosity influenced adolescent risky sexual behavior through its impact on authoritative parenting, adolescent religiosity, and adolescent affiliation with less sexually permissive peers. Some mediating mechanisms differed by the gender of the respondent, suggesting a “double-standard” for daughters but not for sons. Findings also indicated the importance of messages about sexual behavior that are transmitted to adolescents by their peers. Theoretical and policy implications of the findings are discussed.  相似文献

Chinese foreign policy has multiple sources, and the incentives that are driving its behaviour have grown from the domestic/international, as well as from regional, economic, normative, multilateral, and cultural levels. Foreign policy-making in China is becoming increasingly complex and sophisticated. This special issue is drawn from some edited papers presented in the joint workshop between Fudan and Durham Universities on Chinese foreign policy on 29–30 March 2010. By assessing the economic, domestic, regional, global and cultural sources of Chinese foreign policy, we aim to illustrate the various sources and to locate possible ways to consolidate the transitional process, and to spur future endeavour facing China’s foreign policy.  相似文献

Throughout the Global South, diverse non-state actors have historically played critical roles in enabling populations to meet their basic needs, whether by providing or mediating access to social benefits and programs. To date, little research explores non-state social welfare, particularly in the Global South, and existing studies tend to focus on technical and administrative concerns while neglecting the potential political ramifications. This introductory essay aims to conceptualize and theorize the politics of non-state social welfare. We highlight three dimensions of the political consequences of non-state social welfare, including the implications for state capacity, equity of access to social welfare, and experiences of citizenship. Based on this framework as well as the findings of the empirical contributions to the special issue, the essay concludes that non-state provision may pose more political challenges than proponents recognize, but its effects are ultimately contingent on the types of relationships between state and non-state providers.  相似文献
