Spatial Interpretation of the Wooden Arch Gallery Bridges in Northeast Fujian from the Perspective of Behavior Space

On the basis of investigating wooden arch gallery bridges in China,perspectives of researchers studying wooden arch gallery bridges in northeast Fujian Province were reviewed,and the innovativeness of researches from the perspectives of cultural geography and significance of wooden arch gallery bridge for the locals’behaviors was proposed.Youxi Village in Qinyang Town,Shouning County,known as the Village of Gallery Bridge,was taken for example to analyze physical,spiritual and social properties of its wooden arch gallery bridge spaces.Wooden arch gallery bridge is an effective boundary point of settlement space,constituting natural ecological spaces and man-made physical spaces of rural settlements.And as a type of building space,wooden arch gallery bridge expands settlement spaces,contributes to settlement cultures,and enriches spiritual connotations of regional cultures.In northeast Fujian,wooden arch gallery bridge is an important social space for the locals’daily life by carrying on living,production and spiritual functions.

Trust Evaluation Model Based on Behavior Space Classification for Ad Hoc Networks

Trust management frameworks are used to evaluate and manage trust relationships between network nodes and enhance network security. However, trust management frameworks themselves are vulnerable to attacks. Attacks against trust management frameworks are described in this paper with a trust management framework to resist them. The trustworthiness between nodes is evaluated to classify node behavior using a three-dimensional classifier based on a fuzzy integral. Different behaviors are mapped to different behavioral spaces to detect malicious nodes and identify their behavior types. The security of ad hoc networks is then improved by various measures to handle different types of malicious behavior. Simula- tions of the model on the System In The Loop （SITL） platform show that this trust management framework can separate normal nodes and malicious nodes and can distinguish different types of malicious nodes.

Effects of different feeding methods and space allowance on the growth performance, individual and social behaviors of Holstein calves

The importance of nutrient provisions and weaning methods for calves has been well established over the past few years,while as increasing interest has focused on contribution of animal behavior and their overall performance in production regimes.The present study investigated the effects of feeding methods and space allowance on growth performance,individual and social behaviors in Holstein calves.Twenty-four Chinese Holstein male and female calves were allocated to either an individual or group of 6 and fed either with a bucket or a teat.Milk replacer,calf starter,and Chinese wildrye were offered during the experiment.A fecal index used in the present study was defined as the total fecal scores/total number of calves in each treatment.The results showed that there was no significant difference among the 4 treatments in terms of feed intake,body weight,average daily gain,and fecal index.For the feeding behaviors,the ingesting milk time and ingesting milk rate were significantly affected by space allowance,while the feeding methods showed a significant influence on the bunting behavior of the calves.There was no significant difference among the 4 treatments in terms of licking fixtures,self-grooming,and lying down behaviors,irrespective of the feeding method or space allowance.However,sucking an empty bucket or the teat was significantly affected by the feeding method.Several selected group behaviors were examined in the present study,and similar values for sniffing the other calves,social grooming,and cross-sucking behaviors were observed.Overall,the present study demonstrated that different feeding methods and space allowances had a significant effect on the feeding behavior of calves,while the feed intake,growth performance,health condition,individual and group social behaviors were not significantly influenced.Furthermore,under intensified production systems,Holstein calves raised in a group may obtain a similar production performance,thus reducing management input and profitability compared with those kept individually.However,there may be competition during the feeding period.

Study on Low-Temperature Traction Behavior of a Space Lubricating Oil No.4116

The traction behavior of space lubricating oil No. 4116 was measured and analyzed at various oil inlet temperatures below 0 ℃ and various rolling speeds under normal loads by a test rig simulating the operating conditions of space bearings. A traction coefficient calculation model was presented. The rheological property and rheological parameters of the lubricant at a low oil inlet temperature were analyzed based on the Tevaarwerk-Johnson model. The results showed that the lubricating oil No. 4116 was sensitive to the rolling speed and had lower sensitivity to the normal load. This lubricating oil is more suitable for applications under high speed when it is used below 0 ℃. It behaves as an elastic-plastic fluid operating below 0 ℃. Both the average limiting shear stress and the average elastic shear modulus have a negative correlation with the rolling speed and oil inlet temperature and have a positive correlation with the normal load.

阈限空间与临界消费:城市书店的内在属性与经营路径研究

近年来,当学者们普遍以公共空间为路径阐释书店空间时,其空间属性的特殊性就被遮蔽起来。事实上,书店早已不只是销售图书的终端,亦不是纯粹的公共空间,而是演变成一种兼具精神消费与实物消费、个体消费与集体消费的阈限空间,既是群体意志与个体消费行为表达的场所,亦是某种非公非私的、具有临界性的“飞地”;既具有内在空间的生产性,亦以舒适物的形式通过正外部性形成对周边业态的促进。文章尝试以消费学为视域重新审视书店的空间属性与消费意义,进而从学理和实践两个层面探究城市书店的未来通路。

面向数字社会的学生社群互动行为分析

命运与共是当今世界的显著标志,人际交往对于社会生产与发展具有重要现实意义。信息技术的发展扩大了学生的成长空间,数字交往成为当代学生主要的人际互动形式,网络社群则成为学生成长的主要空间。然而,这也导致学生直面数字社交带来的交往异化和主体性丢失问题。因此,研究从交往理性的视角构建了数字社会CSS架构,涵盖数字文化(Digital Culture)、主体空间(Individual Space)和社会秩序(Social Order)三个层面,该架构为数字社会成员在新时代的生存发展和社会交往提供了可信机理。基于此架构详细分析了个体面向数字社会所应具备的胜任能力,具体包含数字文化中的工具意识、数字素养和主体效能;主体空间中的自我意识、身份认同和行为约束以及社会秩序中的群体意识、情绪驾驭和社会参与。

高速公路隧道反光条间距对跟驰行为的影响

文中根据跟驰过程隧道反光条的刺激次数计算出相应的反光条间距,选取32名驾驶员作为被试,通过UC/Win-Road开展模拟驾驶实验,记录隧道反光条间距为0、280、140、100、70、50 m方案下的行车数据,采用第一次减速车距、跟车车距和车道偏移等指标验证方案的有效性.结果表明:相较于改善前,不同间距下隧道反光条都会增大第一次减速车距和跟车车距,减少车道偏移量,提升隧道行车安全性.但是当隧道反光条间距过大、刺激次数少时,改善效果较差,当隧道反光条间距过小、刺激次数多时,会引起负面影响,导致车距和偏移改善效果不显著,其中隧道反光条间距为140 m、刺激2次时最为合理,车距和偏移改善效果较好.

基于科教融合的行为舒适型微型建筑空间设计研究

高密度城市中的微型居住空间能够在一定程度上解决中低收入人口或流动人口的居住问题。但狭小的空间会造成居住者在行动方面的困难。这种困难即行为上的不舒适问题,可能会导致久坐、久躺等不良生活方式的形成,进而影响居住者的身体健康。因此,本文以科教融合的方式进行研究,依据人体生理行为上的特点,提出一种能够提升身体活动舒适性的微型居住空间设计方法,进而促进居室空间形态的个性化生成和学生建筑设计能力的培养。

从里坊街巷到完整社区:我国社区的模式演变、规划实践及趋势展望

从传统向现代转型的中国式现代化语境下,中国社区历史脉络与现代社区演化路径的纵贯研究较为缺乏,作为新时代城乡社区建设行动指南的完整社区亦尚未建立适切的理论框架。为了更系统地剖析从古至今中国社区发展的历史和特点,基于文献研究与规划实践解读,构建一个理解中国社区演进的综合框架:从国家与社会视角分析古今社区的重要模式演变,从制度与生活视角解析建国以来社区的发展转型,从行为与空间视角剖析近年来社区的规划治理实践。鉴于此,文章进一步提出基于“制度—行为—空间”三位一体的完整社区理论分析框架。研究认为,唐宋之际从里坊制到街巷制,表征为传统基层社会从国家中的社会转向社会中的国家;改革开放以来从单位制到社区制,意味着现代社区从国家全能管控转向社会有限自组织;现代社区从单位大院、居住小区到完整社区的转变,表明社区发展的底层逻辑从制度支配生活转向生活倒逼制度生活化。最后,指出完整社区应是公共服务均等、居民生活满意、治理制度良善三个维度高质均衡的城市社会单元,作为中国式现代化社区的一种理想图景,希冀对未来社区的理论建构与规划实践有所助益与启发。
