场域理论与马克思主义法学理论的发展——以法官审判行为为例的场域分析

布迪厄的场域理论是对我国马克思主义法学理论的必要补充。场域理论可以作为研究我国现阶段法官审判行为的分析工具。现阶段我国法官处于"法律场域"、"权力机构场域"、"传统文化场域"、"社会生活场域"等多重场域中,而"多重场域彼此影响",这种影响是通过场域中个体的实践活动实现的,当多重场域的影响与法官的审判行为发生冲突时,法官的审判行为就具有了选择的可能,这种经过选择的审判结果往往是偏离法律规范的,而隐藏在背后主导法官审判选择行为发生的深层次原因就是惯习。     

HPFL加固RC梁抗弯疲劳性能试验研究

为了研究用高性能水泥复合砂浆钢筋网(High performance ferrocement laminate,简称HPFL)加固钢筋混凝土梁的疲劳性能,对11根对比梁和加固梁进行了静力和疲劳性能试验。试验结果显示,与未加固梁相比,加固梁的疲劳性能有明显改善,疲劳寿命提高16%~104%。在经过相同的循环次数之后,加固梁跨中挠度减小30%以上,混凝土和钢筋应变有所降低,裂缝宽度和间距也显著减小。没有植剪切销钉的构件发生了加固层与构件混凝土之间的界面剥离破坏,但端部植入一定数量的剪切销钉后就能避免发生这种破坏模式。     

基于新能源高频大数据的驾驶行为与能耗分析

近年来,在新能源汽车示范推广和财政补贴的大背景下,我国新能源汽车产业快速发展。但与传统燃油车相比,新能源汽车的技术成熟度尚且不足,在研发、运行阶段仍存在诸多问题等待解决,其中能耗和续航问题的关注度尤为突出。本文基于车载终端采集到的新能源高频大数据,提取能够反映驾驶行为精细时空变化特征的特征参数集,采用主成分分析方法将特征参数集进行优化,利用K-means算法实现驾驶行为的自动分级,并分析了不同级别驾驶行为的能耗分布情况。分析结果表明,驾驶行为影响新能源汽车能耗水平,其中平稳驾驶对应的能耗较低,对新能源汽车产品升级和用户驾驶习惯优化具有一定的参考价值。

大跨度混凝土斜拉桥拆除方案设计

上海泖港大桥老桥为(85+200-85)m双塔双索面预应力混凝土斜拉桥,采用塔梁固结、塔墩分离的结构体系.随着航道等级提升,该桥桥下净空无法满足通航需求,且原结构损伤较为严重,对其进行拆除.考虑紧邻新建主桥、老桥斜拉索损伤等不利影响,提出一套以“先上后下、逆序拆除”为原则的拆除方案,依次对桥面系、主梁、斜拉索、桥塔和下...     

Advances in consumer electric vehicle adoption research: A review and research agenda

In spite of the purported positive environmental consequences of electrifying the light duty vehicle fleet, the number of electric vehicles (EVs) in use is still insignificant. One reason for the modest adoption figures is that the mass acceptance of EVs to a large extent is reliant on consumers’ perception of EVs. This paper presents a comprehensive overview of the drivers for and barriers against consumer adoption of plug-in EVs, as well as an overview of the theoretical perspectives that have been utilized for understanding consumer intentions and adoption behavior towards EVs. In addition, we identify gaps and limitations in existing research and suggest areas in which future research would be able to contribute.     

Behavior of taxi customers in hailing vacant taxis: a nested logit model for policy analysis

This study models and examines the taxi customers' preferences for hailing vacant taxis on streets. A stated preference survey was conducted to randomly select and interview 1242 taxi customers at taxi stands and pedestrians on streets, who had experiences of taking taxis recently, about their choices under different given hypothetical scenarios. In total, 4968 observations were collected and used for developing the discrete choice models for the analysis. To account for the potential correlations among alternatives, two nested logit models are developed, calibrated, and compared with a standard multinomial logit model in the investigation. The results of likelihood ratio test demonstrate that one of the developed nested logit models is better than the standard multinomial logit model to describe the search behavior of taxi customers. The model results also show that the walking time to and the waiting time at the location for hailing taxis, the extra travel time to the destination because of local circulation for finding a way from the pickup location heading to a passenger's destination, as well as the taxi customers' perceptions for walking to and waiting at taxi stands were found as significant factors to influence their decisions. In addition, the results of market segmentation analysis illustrate the variations in taxi‐search strategies of taxi customers in different districts and regions. Some policy implications on introducing more taxi stands and improving the utilization rates of taxi stands are also discussed. We believe that the proposed models, findings, and discussion are useful for developing micro‐simulation models to evaluate the performance of road traffic networks with taxi services and developing simulation‐based optimization models to answer policy questions related to taxi services.

永恒的人类之善--谈孔子和亚里士多德中庸思想的契合

孔子与亚里士多德处于公元前四五世纪中西轴心时代,相差一百六十多年,地域、国家、民族、时代、文化的差异并没有阻隔他们心灵、精神的暗相与会,用美国新人文主义杰出代表白璧德的话来说他们都见证了人类正常经验的核心。在中庸这一思想上,孔子和亚里士多德惊人一致地阐明了中庸是天人合一或与神合一的最高的善,是万事万物达到最佳状态的度,是人类最高的道德境界;人类行为若以善为内涵,体会完美的中庸之道,就能实现完满的幸福与和谐。
