The aim of this study was to simulate the low temperatures that insects could experience between the time being sampled from cadavers and their arrival in the laboratory. This was in order to investigate the effect of low temperature on development of maggots. At different stages of development, individuals of Protophormia terraenovae (Robineau-Desvoidy) reared at 24 degrees C were submitted to a temperature of 4.0+/-0.5 degrees C for a period varying from 1 to 10 days. Independent of the stage of development at which the insects were refrigerated, the treatment induced significant changes on the duration of development. The effect of low temperature on the developmental time between the return to 24 degrees C to adult emergence depended on the larval stage that was refrigerated. When first instar larvae and prepupae were refrigerated, the time to emergence at 24 degrees C decreased with an increase of duration of the refrigeration period. Time to emergence increased under the same conditions when second instar larvae and pupae were refrigerated. These results indicate that keeping larvae of P. terraenovae at 4 degrees C does not just simply lead to a cessation of metabolism but disturbs the regular development. Ten days of cooling induced an error in estimating post-mortem interval (PMI) of more than 6h. 相似文献

This article follows the efforts of white settlers to impose cotton as an export crop in Natal and Zululand. Touted as a commodity capable of remaking land and life in the region in the 1850s, the 1860s, and again in the 1910s and 1920s, cotton never achieved more than marginal status in the region's agricultural economy. Its story is one of historical amnesia: although faith in the region's cotton prospects dipped following each spectacular failure, it was routinely resurrected once previous failures had been accounted for, or memories of them had faded. Two crucial issues are at the centre of this episodic history. First, I explore the logistics of planned expansion, and the reasons for the repeated collapse of cotton-growing schemes. Second, I unravel the side effects of these difficult and disappointing efforts and argue that, despite repeated failure, cotton facilitated important structural changes to the region's agricultural, political and economic landscape. 相似文献

After strangulation, cervical arterial injuries (CAI) are uncommon. We report three unusual cases where strangulation induced immediate stroke. CAI were examined using brain CT scan and Doppler ultrasonography in the three cases and then by autopsy in one of the victims. One of the two victims who survived the attempted strangulation had a unilateral carotid dissection, whereas in the other victim, no arterial dissection or thrombosis was observed. As regards the deceased victim, the autopsy confirmed the bilateral dissection showed on CT scan and Doppler ultrasonic examination and revealed that both carotid arteries were dilated up to two times the normal diameter. Microscopic examination showed a major bilateral hemorrhagic dissection of the media with obliterating fibrous endarteritis lesions associated with inflammatory damage. CT scan with arteriography does not demonstrate all the different types of arterial injury, particularly atheromatous embolism, direct compression, or prolonged spasm. Thus, traditional autopsy remains an essential forensic tool after strangulation to show the type of CAI. 相似文献

IntroductionThe use of methadone in opioid maintenance treatment (OMT) is potentially associated with a number of adverse effects and the risk of fatal toxicity. Increased methadone availability may lead to an increase in methadone-related deaths. We have investigated methadone-related deaths in Norway over the period 2000–2006.Materials and methodsMethadone-positive samples over the period 2000–2006 were identified from forensic toxicological investigations, and demographic and toxicological data were retrieved. The cases were cross-linked with the Norwegian Cause of Death Registry and regional OMT registers.ResultsA total of 312 individuals had died after taking methadone over the period 2000–2006, predominantly men with a mean age of 36. In 85% of cases (n = 264), the deceased had died of a methadone-related intoxication, most often in combination with other drugs, including benzodiazepines, cannabis and other opioids. Only 22% of the deceased had been in OMT at the time of death. A larger proportion of OMT patients had died of causes other than intoxications compared to those not in OMT (30% vs. 8%, respectively), most commonly related to disease.ConclusionsOne methadone-related death occurred, on average, every week over the time period investigated. Only 22% of the deceased were registered in opioid maintenance treatment (OMT) programs. The findings underline the need to control diversion of medication from OMT programs. 相似文献

Abstract This paper presents the first research on cases where offenders initiate contact with other individuals over the internet and incite, or conspire (IIIC) with, them to commit child sexual abuse (CSA). Interviews and record searches were carried out among local police services in the UK. IIIC cases were found to be diverse in terms of their typology but rare with regard to the extent of known cases. They were similar to other CSA in relation to victim and offender characteristics but were distinct with regard to offenders’ modi operandi. IIIC cases should be viewed as an additional and serious category of internet-related CSA, and one about which there needs to be much more awareness and research. 相似文献

The deadlock in the WTO Doha Round has been accompanied by an increased focus on the negotiation of preferential trade agreements, including so-called ‘mega-regionals’. This paper discusses possible implications for—and possible responses by—excluded countries that have little prospects of participating in most of the mega-regionals. A number of complementary avenues are identified through which such countries might attenuate the potential downsides of preferential trade liberalization among large countries, as well as some proposals that would expand the scope to pursue cooperation on regulatory policies in the WTO as opposed to PTAs. 相似文献

By considering cultural practices and preferences in terms of intra-individual behavioral variation it is possible to construct a model of the social world which does not neglect individual singularities and avoids the cultural caricature of social groups. Thus, it becomes clear that the boundary between ??cultural legitimacy?? and ??cultural illegitimacy?? does not only separate different social classes, but divides up the cultural practices and preferences of individuals themselves across all classes. Without challenging the existence of social inequalities in terms of the most legitimate forms of culture, such a scientific point of view allows to establish the marked statistical frequency of individual cultural profiles composed of heterogeneous or dissonant elements. The article considers the socio-historical conditions that produce heterogeneous cultural profiles and shows that these frequent cultural dissonances allow to reinterpret the social functions of culture and to highlight the importance of the study of intra-individual behavioral variations within the framework of a sociology of dispositional and contextual plurality. 相似文献
