The discussion still continues among researchers about the causes for the decline in infant mortality in widespread parts of Europe at the turn of the 19th century. This article is based on sources such as unpublished statistical material from Prussia, parish registers, and lineage and village genealogies. As these sources are broken down by town and countryside and into various phases of infant mortality, they provide evidence for further reflection that may be fruitful. Thus, several causes for the decrease in infant mortality and ways of diffusion can be excluded and the impact of others delimited. The present study concludes that research should pay more attention to changes in infant care than it usually does. 相似文献

AbstractTransit-oriented development (TOD) has been promoted by planners and policy advocates as a solution to a variety of urban problems, including automobile traffic congestion, air pollution, and urban poverty. Since the enhanced accessibility offered by transit proximity is often capitalized into land and housing prices, many express concern that new transit investments will result in the displacement of the low-income populations likely to benefit most from transit access, a phenomenon which we term transit-induced gentrification. Whereas policy advocates have proposed a variety of interventions designed to ensure that affordable housing for low-income households is produced and preserved in areas proximate to transit stations, little is known about the effectiveness of these policy proposals. This article relies on an integrated land use/transportation model to analyze how TOD-based affordable housing policies influence the intraurban location of low-income households. We find that affordability restrictions targeted to new dwellings constructed in TODs are effective tools for promoting housing affordability and improving low-income households’ access to transit while simultaneously reducing the extent of transit-induced gentrification. 相似文献

Abstract: Ehlers–Danlos syndrome (EDS) type IV is a connective tissue disorder characterized by the inability to produce sufficient amounts of collagen or a defect in the structure of collagen. The most serious complications include a rupture of a viscus or vascular rupture with or without mural dissection. Death may result from internal hemorrhage. This report describes three cases of sudden and unexpected death caused by EDS type IV. Two cases involved hemothorax as a result of dissection of the subclavian artery and aorta, respectively. The third case represented spontaneous pulmonary rupture and hemorrhage. A detailed family history should be sought, and additional specimens collected to confirm the diagnosis, including skin fibroblasts for collagen testing and blood for DNA testing. The forensic pathologist should consider the possibility of EDS type IV upon discovery of spontaneous visceral or arterial rupture and should alert the family members of this hereditary and potentially fatal condition. 相似文献

“We need more clips about Putin,and lots of them:” Russia’s state-commissioned online visual culture
In this article, we examine how the Putin government is attempting to respond and adapt to the YouTube phenomenon and the vibrant oppositional online visual culture on Runet. We show how these processes are giving rise to new forms of state propaganda, shaped and driven above all by the quest for high-ranking search-engine results and the concomitant desire to appeal to the perceived new sensibilities of the Internet generation through the commissioning and production of “viral videos.” We focus in particular on the videos created by Iurii Degtiarev, a pioneer in the development of this genre, whose works we explore in light of the “Kremlingate” email leaks, which offer inside information on the strategies and aims being pursued on the online visual front of the campaign to manage the Russian mediascape, and Degtiarev’s own reflections on this subject. Examining the output of young creatives patronized by the Kremlin offers a “bottom-up” view to supplement studies of the Russian ideological and media landscape as shaped by “political technologists” such as Vladislav Surkov and Gleb Pavlovskii. 相似文献

An ingestion of an unknown quantity of mirtazapine in a suicide attempt leading to death is described. Sertraline and amitriptyline have been co-ingested. Because mirtazapine is reported to be relatively safe in overdose, body fluids and tissues were investigated for both mirtazapine and desmethylmirtazapine by high-pressure liquid chromatography/tandem mass spectrometry following liquid-liquid extraction. The limit of detection was sufficiently low to also apply the assay in pharmacokinetic studies. The levels of amitriptyline and nortriptyline were very low (38 and 19 ng/mL femoral venous blood) and the amount of sertraline in blood taken from the femoral vein (880 ng/mL) was considerably lower than those seen in overdosage. Accumulation of mirtazapine and N-desmethylmirtazapine was evident in fluids and tissues involved in enterohepatic circulation and excretion. The concentration determined in a brain sample suggests a contribution of the metabolite to the drug's pharmacodynamic activity. Based on literature data, significant adverse or synergistic effects among the drugs detected as well as adverse reactions such as a serotonin reaction appeared less probable. Mirtazapine exhibits alpha(1)-antagonistic properties on the cardiac-vascular system and may cause hyponatraemia. In the face of the cardiac findings at autopsy and the lack of an apparent cause of death, these effects of mirtazapine may have initiated a process leading to death. 相似文献
