体育新闻报道畸变现象及产生原因的社会学透析   总被引：2，自引：0，他引：2  

李世新 《南京体育学院学报(社会科学版)》2006,20(4):59-61

采用文献资料法、逻辑分析法对体育报道的畸变现象进行了论述:暴力化、色情化、失实报道屡见不鲜、恶炒新闻层出不穷、锦标主义、以成败论英雄的陋习常见、地方沙文主义色彩日益严重等等。并对这些现象产生的原因进行了透析,认为产生这些现象的原因有:媒体从业人员素质的匮乏、市场竞争的日趋激烈、大众文化娱乐性的推波助澜、体育报道远离政治规范孕育畸变土壤等。  相似文献

IntroductionBlood gas analysis (BGA) is an essential test used for years to provide vital information in critically ill patients. However, the instability of the blood gases is a problem. We aimed to evaluate time and temperature effects on blood gas stability.Materials and methodsArterial blood was collected from 20 patients into syringes. Following BGA for baseline, syringes were divided into groups to stand at 4°C and 22°C for 30, 60, 90, 120 minutes. All were tested for pH, partial pressure of carbon dioxide (pCO₂), partial pressure of oxygen (pO₂), oxygen saturation (sO₂), oxyhemoglobin (O₂Hb), sodium, potassium, glucose, lactate, oxygen tension at 50% hemoglobin saturation (p50), and bicarbonate. A subgroup analysis was performed to detect the effect of air on results during storage. Percentage deviations were calculated and compared against the preset quality specifications for allowable total error.ResultsAt 4°C, pO₂ was the least stable parameter. At 22°C, pO₂ remained stable for 120 min, pH and glucose for 90 min, lactate and pCO₂ for 60 min. Glucose and lactate were stable when chilled. Air bubbles interfered pO₂ regardless of temperatures, whereas pCO₂ increased significantly at 22°C after 30 min, and pH decreased after 90 min. Bicarbonate, sO₂, O₂Hb, sodium, and potassium were the unaffected parameters.ConclusionsCorrect BGA results are essential, and arterial sample is precious. Therefore, if immediate analysis cannot be performed, up to one hour, syringes stored at room temperature will give reliable results when care is taken to minimize air within the blood gas specimen.  相似文献   

2005年3月10～12日嘉兴市寒潮大雪成因浅析     

李海军  李云泉 《科技通报》2007,23(5):641-645

分析2005年3月10～12日嘉兴市寒潮、大雪天气过程发现:强寒潮是由乌拉尔阻高东移南垮引起强冷空气南下和前期明显回温共同造成的。500 hPa南支槽前的西南暖湿气流为大雪天气提供了源源不断的水汽;物理量诊断显示,高层辐散、低层辐合和弱的不稳定能量,为大雪的产生提供了动力抬升条件;高空西南暖湿气流突然加强,近地面层有大片逆温层存在,是预报大雪的关键,为今后预报大雪起到了一定参考的作用。  相似文献

Do organizational variables influence satisfaction with nursing student practices?     

《Studies in Educational Evaluation》2021

Clinical practices are a vital component in the education of registered nursing students. This study analyzed the influence of organizational variables on satisfaction with clinical practices. A cross-sectional study design involved 572 registered nursing students. Two statistical methodologies, hierarchical regression models and qualitative comparative analysis of diffuse sets, were used for data analysis. In the hierarchical regression models the number of students supervised predicted satisfaction with clinical educator (β = -.22; p ≤ .001), environment (β = -.13; p ≤ .05) and overall satisfaction (β = -.15; p ≤ .05). However, in the qualitative comparative analysis, the type of center, as well as the number of services assigned to the clinical educator and the number of students per clinical educator period were conditions that influence satisfaction with clinical practices. The type of center and the clinical educator are key factors related to registered nursing students’ satisfaction with clinical practices.  相似文献

轴向扩散下不可压饱和多孔简支弹性杆的弯曲     

杨骁  刘鑫 《上海大学学报(英文版)》2008,12(1):1-6

Based on the mathematical model of the bending of the incompressible saturated poroelastic beam with axialdiffusion, the quasi-static bendings of the simply supported poroelastic beam subjected to a suddenly applied constant loadwere investigated, and the analytical solutions were obtained for different diffusion conditions of the pore fluid at the beamends. The deflections, the bending moments of the solid skeleton and the equivalent couples of the pore pressures werepresented in figures. It is also shown that the behavior of the saturated poroelastic beams depends closely on the diffusionconditions at the beam ends, especially for the equivalent couples of the pore pressures. It is found that the Mandel-Cryereffect also exists in the bending of the saturated poroelastic beams under specific diffusion conditions at the beam ends.  相似文献
