This article is an examination of Hong Kong's importance within British‐American security arrangements in the Far East during the presidency of Dwight D. Eisenhower. Archival evidence indicates that the Eisenhower Administration accepted a greater deal of commitment to the defence of Hong Kong during the 1950s — a period of significant hostility between the United States and the People's Republic of China. To understand this policy evolution in the broader context, this study evaluates the differences in British and American attitudes towards China during the 1950s and the effect of this on US policy towards Hong Kong. 相似文献

Primary study of vascular endothelial growth factor immunohistochemical staining in the diagnosis of early acute myocardial ischemia 总被引:5,自引:0,他引:5
The expression of vascular endothelial growth factor (VEGF) in the model of rat early acute myocardial ischemia was studied by Strept-Avidin-Biotin-Peroxidase Complex (SABC) immunohistochemical staining. After ligating the anterior descending branch of the left coronary artery, an initial rapid (30min) positive expression of VEGF in myocardial ischemic areas was observed, the intensity of positive expression of VEGF increased with the continuation of myocardial ischemia. After 5h infarction, the strongly positive myocytes of SABC-VEGF staining were predominantly limited to perimyocardial infarction areas. No positive expression of VEGF was found in the control group. These findings suggested that SABC-VEGF method could give a sensitive, specific, simple and objective morphologic evidence to the diagnosis of sudden cardiac death caused by acute early myocardial ischemia. 相似文献

The new element in governance is social media. Inexorably, its fertile networks of shared information shift power from authorities to citizens and amateurs, including to the “unknown” experts in the “dorm rooms and edges of society” who drive innovation. Tweets may bust trust and undermine authority, but can social media also be a tool for building consensus through deliberation and negotiation among interests? When it comes to governance, is crowd‐sourcing any better than populism at generating collective intelligence instead of disruptive “dumb mobs?” Can networks aid the self‐administration of society, or does that take institutions with governing authority? In this section, leading Silicon Valley entrepreneurs, technologists and network theorists from Google, Microsoft and the MIT Media Lab join with political scientist Francis Fukuyama and top thinkers from Asia to address these issues. 相似文献

Determination of drug levels and the effect of diazepam on the growth of necrophagous flies of forensic importance in southeastern Brazil. 总被引:1,自引:0,他引:1
Larvae of Chrysomya albiceps (Wiedemann) and Chrysomya putoria (Wiedemann) (Diptera: Calliphoridae) were reared on tissues from rabbits administered twice the lethal dosage of diazepam in order to study the effects of this drug on the development of these two species. The rabbits were given 50mg of diazepam via ear vein infusion. From 18 to 54h, larvae feeding on tissues containing the drug developed more rapidly than larvae from the control colony for both fly species. The time required for pupariation and adult emergence was significantly greater for colony fed on tissues from diazepam dosed rabbits than for the control ones. These differences are significant for they are large enough to alter the estimate of postmortem interval based on fly development. The presence of diazepam could be detected through gas chromatography-mass spectrometer (GC-MS) in all rabbit samples and in almost all diptera samples in this experiment. 相似文献

Using ABH enzyme-labeled monoclonal antibodies, the authors could rapidly detect the ABO group from body fluids and body fluid stains by the dot enzyme-linked immunosorbent assay (dot-ELISA). In this test, the antigen was immobilized on nitrocellulose paper; the entire piece of paper was coated with an appropriate dilution of enzyme-labeled McAb directly against the antigen of interest; and, finally, 3,3'-diaminobenzidine (DAB) substrate solution was added. The site of a positive reaction is clearly visible as a brown spot. We analyzed 521 samples and got satisfactory results. We also analyzed 99 practical case samples by this method and achieved the same results as those obtained by other researchers using other methods. This method is accurate, simple, direct, rapid, and sensitive; it also produces easily observed results, requires no equipment, and can be completed in 30 min. The test proved to be clearly more sensitive for the detection of the ABO blood group in secretor saliva than the conventional hemagglutination inhibition test. Also saliva diluted 10(-4) to 10(-5) and the ABO group of nonsecretor saliva and urine could be easily detected by this method. 相似文献

For 500 years the West was on the rise, culminating in Globalizaiton 1.0—the open system of trade, information flows and the spread of technology on the terms and in the image of the West. The benefits of that system over the last 30 years have led to the rise of the emerging economies. As a result we are entering the new era of Globalization 2.0 characterized by new forms of non‐Western modernity and the interdependence of plural identities. The advent of this new era has been hastened by the fiscal and financial crisis in Europe and the United States. Turkey, with its Islamic‐oriented democracy that has become a template for the liberated peoples of the Arab Spring, and China, with its effective neo‐Confucian form of governance, are the most sharply defined new players in this multi‐polar and multi‐dimensional world. In this section, one of Turkey's most insightful sociologists examines the post‐secular transformation of that nation. One of China's more provocative philosophers proposes a hybrid model that combines what has been learned from the experience of Western and Chinese governance in a way that “enhances democracy” in both systems. 相似文献
