交通运输与区域经济发展耦合研究综述

为全面掌握交通运输与区域社会经济发展国内外研究现状,关键技术以及主要学术成果、结论。本文从Web of Science数据库和CNKI数据库中选取近20年的文献,借助文献可视化软件VOSviewer对所有文献进行分析。结果表明美国、德国、法国在此方面研究起步较早;研究热点主要围绕交通运输与区域经济的协同发展、产业结构、产业集聚、耦合协调模型等方面展开。未来研究应结合大数据分析,聚焦具体区域交通运输与社会经济间耦合协调度,促进交通运输与区域经济协调发展。     

Evaluating the knowledge of experts in the maritime regulatory field

Regulations are introduced by the International Maritime Organization (IMO) into the maritime industry as the result of safety accidents and/or pollution incidents. When there is lack of historical data, then the IMO appoints experts in order to collect information regarding the costs and benefits generated to a stakeholder of the maritime industry once implementing a maritime regulation. Therefore, the role of experts in providing qualitative and quantitative information is crucial with respect to the quality of the maritime regulatory process within the IMO or other regulatory authorities. In this article, a methodology is proposed involving common criteria in determining the expertise of an individual in the maritime regulatory field. As essential part of the research methodology, analytic hierarchy process (AHP) is utilized to determine the expertise of an individual based on his/her own judgements. The regulatory authorities and other stakeholders of the maritime industry may use this method when selecting experts for decision-making. In this article, a simulation is carried showing the potentials of the AHP methodology in expertise evaluation followed by a case study.

基于模糊层次数值型数据库发现一般化模糊关联规则

关联规则发现是数据挖掘研究领域中的重要内容之一,而以自然语言描述的模糊关联规则更符合人类的思维方式,在决策中占据重要作用。基于属性间通常还存着更高层次的抽象,即呈现出层次结构尤其是模糊层次结构这一事实,通过把经典的模糊理论与关联规则发现算法相结合,提出了在模糊层次结构下从数值型数据库中挖掘一般化模糊关联规则的相应算法。     

Papahānaumokuākea: Integrating Culture in the Design and Management of one of the World's Largest Marine Protected Areas

Papahānaumokuākea Marine National Monument is one of the world's largest marine protected areas and was designated the first mixed conservation site in the United States due to its natural and cultural importance. It is also the world's first cultural seascape, being recognized for its continuing connections to indigenous people. As the westernmost place in the Hawaiian universe, many believe these islands and seas are the pathway that Native Hawaiians travel after death, returning to pō (night; realm of the gods). This intimate kinship has profound implications for contemporary management. Current management emphasizes integration of science, policy, cultural knowledge, traditions, and practices to create successful management strategies appropriate for both natural and cultural resources. This management is based on Native Hawaiian values and practices that incorporate observation and understanding of the natural world, indigenous principles and philosophies, cultural norms, community relationships, and unique epistemologies deeply imbedded in and formed by relationships of people with place. A cornerstone of this effort has been the direct involvement of cultural practitioners in policy, management, education, and research. This biocultural approach has led to more effective management of the monument and serves as a model for conservation around the world.     

基于粗糙-模糊软计算的船板线加热成形加工参数预报方法

提出一种基于粗糙-模糊软计算的建模方法,构造一种基于贴近方向修正的高精度模糊推理算法,通过有限元分析(FEA)建立板材线加热成形工艺信息系统,根据粗糙集软计算获取线加热成形的工艺规律,运用模糊推理实现加工参数的快速准确预报。粗糙-模糊建模适用于线加热成形过程的静态或动态模型的构建,为实现该工艺的智能建模与控制提供一种新的技术手段。     

铁路乘客艾滋病知识、态度、行为调查分析

目的　调查铁路旅客的艾滋病相关知识、态度和行为情况,为列车开展艾滋病宣传教育提供理论依据。方法　对6趟旅客列车乘客进行抽样问卷调查,调查结果进行统计分析。结果收回有效调查问卷2 083份,艾滋病一般知识正确回答率55.83% ~92.03%,传播途径59.67%~93.52%,临床知识59.00%~77.34%,预防控制68.75%~88.86%,态度行为48.25%~94.33%,政策法规67.64%~84.88%。正确回答率无性别差异(P>0.05);一般知识、传播途径、行为态度存在结婚与否的差异(P<0.05);受教育程度上除一般知识外,其它都有显著性差异(P<0.01)。结论　铁路乘客对艾滋病知识、态度、行为的正确回答率,原则性问题高于具体问题, 71%以上乘客愿意接受健康教育和AIDS教育。针对铁路乘客流动性强的特点,列车上艾滋病宣传教育内容要注重知识具体化。
