This study explores the role of the news media in asymmetrical conflicts after countries have signed a peace agreement. While most research has focused on the inherently negative role the press plays in attempts to bring peace, this study attempts to look at this issue using a more dynamic perspective. The theoretical argument focuses on how political factors affect the quantity and quality of the news flow and some of the ways in which leaders can sometimes overcome the obstacles they face in promoting encouraging news about peace. The model considers two political factors that have a major impact on media performance: the relative level of political power of the two sides and the varying amount of hostility. To illustrate the importance of these factors we focus on the flow of news between Jordan and Israel between 1999 and 2002. The major findings from content analyses of news articles ( N = 859) appearing in both countries show that while Jordanians are exposed to massive amounts of mostly negative information about Israel, the Israeli public reads almost nothing about Jordan. Despite all this, it was also found that the initiation of diplomatic relations between the former enemies allowed for the creation of important 'news slots' that were previously unavailable. This development created space for less threatening types of news and also allowed leaders from both Jordan and Israel to initiate some positive stories about peace, even during some of the darkest periods. 相似文献

During the COVID-19 pandemic, many rumors and conspiracy theories spread in various media outlets. The purpose of this study is to reveal the nature of the misinformation detected by fact check platforms that spread in the Fragile Five countries. To determine the themes of misinformation about COVID-19 and from which media it is disseminated are a possible way to prevent it. The data of the study were obtained from International Fact-checking Network's CoronaVirusFacts database. One thousand seven hundred thirty-four piece of misinformation collected by web scraping method during the period January 24, 2020 to November 14, 2020 and analyzed with MAXQDA Analytics Pro 2020. As a result of the research, it was found that rumors (96.3%) spread more in the Fragile Five countries than conspiracy theories (3.7%). While the main theme of the rumors is about illness (26.9%) and diagnosis-treatment (25%), conspiracy theories are mostly related to the cause of the disease (68.8%). 53.06% of misinformation was spread through the Facebook platform. 15.32% on Twitter; 13.34% on WhatsApp. Misinformation has been heavily false (85.12%) in both rumor and conspiracy theories. In the second place, misleading (10.09%) news spread. 相似文献

The proposed rule for electing members to the Welsh Assembly gives each voter two votes, to cast at the Parliamentary constituency level, and at the bigger European constituency level. Half of the members are to be elected for the Assembly by a form of proportional representation, where party support is calculated by aggregating the two votes. The voters will be allowed to cast the second vote for a different party than the one for which they voted at the parliamentary level. This additional degree of freedom can frustrate the objective of obtaining better correspondence between party support and the number ofseats. 相似文献

The present study explores toxicologic significance of blood cyanide concentrations in fire victims. Headspace gas chromatography was used for cyanide detection. Analysis of blood samples from ten fire victims (postmortem interval = 8 h to 3 to 5 d) detected zero to 11.9 mg/L of cyanide and a large difference in cyanide concentrations among victims. Carboxyhemoglobin (COHb) saturation was in the range of 24.9 to 84.2%. To examine the effects of methemoglobinemia and postmortem interval on blood cyanide concentrations in fire victims, an experiment was carried out using rabbits as the animal model. The rabbits were sacrificed by intramuscular injection of 1 mL/kg 2% potassium cyanide 5 min after intravenous injection of 0.33 mL/kg of 3% sodium nitrite (Group A, n = 3) or physiological saline (Group B, n = 6). Average methemoglobin contents immediately before potassium cyanide administration were 6.9 and 0.8% in Groups A and B, respectively. Average cyanide concentrations in cardiac blood at the time of death were 47.4 and 3.56 mg/L, respectively. When blood-containing hearts of the rabbits (n = 3 for Group B) were left at 46 degrees C for the first 1 h, at 20 to 25 degrees C for the next 23 h and then at 4 degrees C for 48 h, approximately 85 and 46% of the original amounts of blood cyanide disappeared within 24 h in Groups A and B, respectively. After the 72-h storage period, 37 and 10%, respectively, of the original amounts of cyanide remained in the blood. When the other three hearts in Group B were left at 20 to 25 degrees C for the last 48 h without refrigeration, cyanide had disappeared almost completely by the end of the experiment. The present results and those published in the literature demonstrate that the toxic effects of cyanide on fire victims should not be evaluated based solely on the concentration in blood. 相似文献

A simple method using purge-and-trap gas chromatography/mass spectrometry (P&T-GC/MS) for forensic examination of oil stains was studied. Carboxylic acids, chosen as target components for discrimination of oil samples, were extracted from stains with ether, methyl esterified by tetramethylammonium hydroxide, and analyzed by P&T-GC/MS. Vegetable oils were discriminated according to their carboxylic acid compositions. Carboxylic acid composition was independent of the substrate material of the stain. Although the carboxylic acid composition of the oil changed on exposure to sunlight, identification of oil was possible for oil stains that had been in the shade, if analysis was made within 20 days. 相似文献

This article reports an autopsy case of sudden death of an infant with an infrequent encephalopathy involving epileptic episodes. The infant was a 1-year and 10-month-old boy, who had a history of the first convulsive seizures in the third month after birth. The clinical diagnosis was described as 'an early infantile epileptic encephalopathy with suppression-bursts' (Ohtahara syndrome). On a winter day, he was collapsed following a high fever and was already dead on the arrival at a hospital. The body was small for the age and poorly nourished. The autopsy and postmortem magnetic resonance imaging scan (MRI) of formalin-fixed brain revealed advanced unsymmetric brain atrophy with cortical dysplasia, which were prominent in the left temporal and right occipital lobes, and sclerotic atrophy of the parahippocampal gyri, additionally showing a feature of the olivo-ponto-cerebellar atrophy. However, the cause of death was pathologically and microbiologically determined as bacterial bronchopneumonia following pulmonary infection of the influenza A virus. In sudden death cases of physically handicapped infants, the investigation of viral infection in consideration of an epidemiological survey is important even when the death can be pathomorphologically explained. 相似文献

Government already pays for more than half of U.S. health care costs, and nearly all universal health insurance proposals assume continued government involvement through tax subsidies and other means. The question of what specific taxes could be used to finance universal coverage is, however, seldom carefully examined, in part due to efforts by health care reform proponents to downplay tax issues. In this article we undertake such an examination. We argue that the challenges of relying on taxes for universal coverage are even greater than is generally appreciated, but that they can nevertheless be met. A proposal to fund a universal health insurance voucher system with a value-added tax illustrates issues that would arise for tax-financed plans in general and provides a broad framework for a bipartisan approach to universal coverage. We discuss significant problems that such an approach would face and suggest solutions. We outline a long-term political and legislative strategy for enacting universal coverage that draws upon precedents set by comparable legislative initiatives, including tax reform and Medicare. The results are an improved understanding of the relationship between systemic health care finance reform and taxation and a politically realistic plan for universal coverage that employs undisguised taxes. 相似文献

The ability to determine sex from unknown skeletal remains is vital, and methods to do this on the various bones of the human skeleton have been researched extensively. Many researchers have emphasized the need for population specific data for methods which are based on measurements, as there are vast differences in body size in various populations. The pelvis is known to be the most sexually dimorphic part of the human body, and no discriminant function formulae for this bone are available for Greek or other Mediterranean groups. The purpose of this study was therefore to develop discriminant functions which can be used for sex determination on measurements of the pelvis of modern Greeks. A sample of 97 male and 95 female pelves in a skeletal collection housed in Heraklion, Crete, was used. Measurements were taken from the articulated pelvis, single os coxae and the sacrum. Discriminant function formulae for all measurements and various combinations were used in order to assess the degree of sexual dimorphism in various parts of the pelvis, and to make the formulae usable on fragmented remains. For the single os coxae, average accuracies of 79.7-95.4% (79.1-93.5% on cross-validation) were found. However, it was found that measurements of the sciatic notch were unreliable and yielded poor results, and it is advisable that this characteristic must only be used as a last resort. Dimensions of the sacrum were not very dimorphic (average accuracy 60.9%), while measurements from the articulated pelvis yielded poorer results than that from single innominate bones. The diameter of the acetabulum was the single most dimorphic characteristic, providing on average 83.9% accuracy when used in isolation. 相似文献
