Once meteorological disaster occurs,using the remote sensing technology to extract disaster area of crops and monitor disaster level has great significance for evaluating disasters and making a timely remedy. This paper elaborated the importance of monitoring agro-meteorological disasters using remote sensing in current special historical period,overviewed remote sensing methods both at home and abroad,analyzed existing problems,made clear major problems to be solved in monitoring agro-meteorological disasters using remote sensing,and discussed the development prospect of the remote sensing technology.展开更多

Our investigation indicates that this phenomenon is significantly less common with increased media monitoring. Houston et al.(2011) find strong evidence that the state ownership of media is associated with higher levels of bank corruption in China, but our study shows that, to a certain extent, media monitoring can curb corruption.展开更多

文摘We analyze data on Chinese non-state-listed firms and find that it is easier for firms with political connections to obtain long-term loans with extended debt maturities than it is for firms without political connections. Our investigation indicates that this phenomenon is significantly less common with increased media monitoring.

文摘目的研究影响甲状腺手术患者术后咽喉部干痛的相关因素。方法选择择期行甲状腺手术的女性患者29例,年龄24~67岁,BMI 18~30kg/m2,ASAⅠ或Ⅱ级。麻醉诱导及气管插管后将套囊充气至20mm Hg,采用压力传感器持续动态监测气管导管套囊压力,每间隔5分钟记录实时数据,并于术后24h评估患者咽痛评分和咽干分级。结果气管导管套囊压力值呈离散分布。多元线性回归模型分析结果显示,年龄、BMI、麻醉时间、套囊压力对咽痛评分均无明显影响;决策树模型分析结果显示,甲状腺手术套囊平均压力≥29 mm Hg时,患者咽干分级为Ⅳ级的几率较高。结论甲状腺手术患者咽干的发生可能与手术操作导致气管导管的套囊压力增高相关。
