Shortest or locally quickest? A prediction-based approach for evacuation choice simulation between multiple staircases

引用

JOURNAL OF SAFETY SCIENCE AND RESILIENCE 2024年第3期5卷 281-294页

作者： hua, ying Zhao, Jincheng Li, Hai-Ting Duan, Liping Shanghai Jiao Tong Univ Sch Ocean & Civil Engn Dept Civil Engn Shanghai 200240 Peoples R China Shanghai Jiao Tong Univ Shanghai Key Lab Digital Maintenance Bldg & Infras Shanghai 200240 Peoples R China

Staircase choice is one of the most critical factors leading to the difference in pedestrian flow and evacuation routes in buildings with multiple staircases. Neither the shortest path to the building exit nor the locally quickest path to the nearest staircase can represent the natural mode of evacuation path choices for an authentic evacuation simulation. Thus, a prediction-based approach is established to predict and simulate evacuation choices, which helps to address three key issues: (1) extracting evacuation data through a controlled experiment; (2) establishing a Logit model for staircase choice prediction based on experimental data; (3) developing a prediction-based cellular automaton model. The proposed approach has achieved the coupling between choice prediction and evacuation simulation. A comparison with Pathfinder software is conducted to reveal the superiority of the prediction-based CA model for simulating staircase choice.

BACKGROUND Prealbumin is considered to be a useful indicator of nutritional status. Furthermore, it has been found to be associated with severities and prognosis of a range of diseases. However, limited data on the association of baseline prealbumin level with outcomes of patients with acute ST-segment elevation myocardial infarction(STEMI) are *** We analyzed 2313 patients admitted for acute STEMI between October 2013 and December 2020. In-hospital outcomes and mortality during the 49 months(interquartile range: 26–73 months) follow-up period were compared between patients with the low prealbumin level(lure with Killip class Ⅲ(9.9%vs. 4.4%, P = 0.034), cardiovascular death(8.4% vs. 3.4%, P = 0.035) and the composite of major adverse cardiovascular events(19.2%vs. 10.3%, P = 0.012). Multivariate logistic regression analysis identified that the low prealbumin level(lue of prealbumin level for predicting in-hospital death was 170 mg/L(area under the curve = 0.703, 95% CI: 0.651–0.754, P< 0.001;sensitivity = 0.544, specificity = 0.794). However, after multivariate adjustment of possible confounders, baseline prealbumin level(170 mg/L) was no longer independently associated with 49-month cardiovascular death. After propensity score matching, Kaplan-Meier survival curves revealed consistent *** Decreased prealbumin level closely related to unfavorable short-term outcomes.

不同于朱熹的性、理与气、心的(在存在论与概念独立上的)二元论,也不同于陆象山与王阳明心与理的关联式的一元论,杨简的思想形态展现出化约式的一元论。杨简以心来吞没理,或者说将理还原为心,注重人的主体精神与心的整全一体。他的心一元论也体现在对“意”的拒斥,意便是区分为二的思维活动。虽然杨简认同道德情感与德性价值,但是道德情感应该如何表现才符合理想秩序,仁义礼智如何实现才是合理正当,对他来说并没有客观的规范,人们只能各自根据其内心所认定为正确的方式行事。因此,其学说无可避免地会导向主观主义。

文章的写作主要有两个目的。第一,阐述狭义的良知——即是非之心——的不同意涵,以及它所支撑的道德框架。文章澄清了两种类型的良知:(1)作为道德判断之能力的良知;(2)作为道德知识和标准的天理良知。此外,文章也通过现象学的描述分析良知的不同特征,良知其它的特征将在另文讨论;如(3)作为道德动力的良知;(4)作为实践能力的良知。良知的这些面相为道德情感所贯穿。第二,在对良知特征的阐释中,文章对治儒家话语中关于良知天理所出现的两种理论问题。第一种理论将王阳明的良知观念看作对特定事件的固化认知,以及即时的反应。这种解读不能真正地认可良知扩展、反思、道德培养和制度革新之可能性。第二种理论将良知理解为不具有具体内容,而仅仅是抽象的本体。通过合理地理解,即从道德情感的视角来检视时,王阳明的良知学说既认可我们总是可以触及良知的具体内容,又提供了深化与培养的可能性。
