在算法技术广泛应用的今天,人们在信息接收和处理方面的茧房倾向愈发加强,算法信息茧房概念因而吸引了极高的关注度。然而信息茧房相关量表具有方法论上的瑕疵:信息茧房厚度是客观概念,而问卷测量的却是个人主观感受。本文提出,采用问卷调查的算法信息茧房研究可以采用着眼于个人因素的“算法信息茧房易感性”概念,并结合深度访谈法、专家焦点小组访谈法,发展出该概念的六个测量指标,并通过两次问卷调查和数据分析开发了包含19题的量表,为算法信息茧房的微观媒介效果研究提供了工具支持。

目的探讨脑血流动力学参数联合动脉血气分析评价早产儿脑损伤的价值。方法观察性研究。抽取2021年5月至2023年5月延安市人民医院收治的92例无脑损伤的早产儿作为对照组,将同期收治的92例脑损伤早产儿作为观察组,观察组脑损伤早产儿根据Sarnat评分分为轻度组(58例)与中重度组(34例)。所有早产儿均接受脑血流动力学和动脉血气分析检查,比较对照组、轻度组与中重度组的脑血流动力学参数[舒张期末流速(Vd)、收缩期峰值流速(Vs)、平均流速(Vm)、收缩期峰值流速/舒张期末流速(Vs/Vd)、阻力指数(RI)]和动脉血气分析指标[二氧化碳分压(PCO_(2))、血氧分压(PaO_(2))、酸碱度(pH值)、乳酸水平]。结果对照组Vd、Vs、Vm与Vs/Vd水平高于轻度组,轻度组高于中重度组(P<0.05);对照组RI水平低于轻度组,轻度组RI水平低于中重度组(P<0.05)。中重度组PCO_(2)与乳酸水平高于轻度组,轻度组PCO_(2)与乳酸水平高于对照组(P<0.05);中重度组PaO_(2)与pH水平低于轻度组,轻度组PaO_(2)与PH水平低于对照组(P<0.05)。Pearson分析显示,早产儿脑损伤严重程度与Vd、Vs、Vm、Vs/Vd、PaO_(2)以及pH值呈负相关,与RI、PCO_(2)以及乳酸呈正相关(P<0.05)。结论脑血流动力学参数联合动脉血气指标与早产儿脑损伤严重程度有一定相关性,可在临床中联合脑血流动力学参数联合动脉血气指标判断早产儿脑损伤情况。

In this paper, we focus on the characteristics of the landslides developed in the epicentral area of AD 1556 M^8.5 Huaxian Earthquake, and discuss their relations to the active normal faults in the SE Weihe Graben, Central China. The results from analyzing high-resolution remote-sensing imagery and digital elevation models（DEMs）, in combination with field survey, demonstrate that：（i） the landslides observed in the study area range from small-scale debris/rock falls to large-scale rock avalanches;（ii） the landslides are mostly developed upon steep slopes of ≥30°; and（iii） the step-like normal-fault scarps along the range-fronts of the Huashan Mountains as well as the thick loess sediments in the Weinan area may facilitate the occurrence of large landslides. The results presented in this study would be helpful to assess the potential landslide hazards in densely-populated areas affected by active normal faulting.

Of course, back in 2002, no one could tell how China＇s financial sector would look like ten years hence. But when in March, 2013, 65-year-old Zhou Xiaochuan was appointed to a further term at the helm of the country＇s central bank, the People＇s Bank of China （PBOC）, it signalled to the world that the country＇s new leaders were resolved to speed up the economic reform.

Like many people his age, Mr. Li had never shopped online. Rather than I click his mouse and pay through his computer, he was a firm believer in ＂What you see is what you get.＂ But, with the launch in mid-August of a major poster campaign promoting huge price reductions for goods bought online, Mr. Li was persuaded by his son to take the plunge, and according to Li, ＂It didn＇t feel bad.＂

The Xi＇an Economic and nological Development Zone e first manufacturing base in Shaanxi province to surpass 100 billion yuan （US$15.96 billion） in annual output value. This achievement is due mainly to the zone＇s efforts in aggregating enterprises, encouraging its development potential and improving its development momentum. Zhang Zhe, deputy director of the zone＇s administrative committee, explained to CIB that the zone focuses on comprehensive services and is exploring a unique scientific development path.
