基于AHP-熵权法的基层地震科普能力评价*

为提高基层地震科普评价工作的客观性和精准性,根据“环境-投入-产出-效果”的评价框架,建立涵盖保障能力、队伍能力、设施能力、产出能力、活动能力5类26项指标的基层地震科普能力评价指标体系,选用AHP-熵权法计算指标的组合权重;以天津为例进行验证,并提出相关工作建议。结果表明:建立的评价模型对于开展定量化的区域基层地震科普能力评价具有较强的参考价值,评价结果与实际情况基本相符;天津市基层地震科普在硬件建设方面取得较好成效,但整体能力依然偏弱,16个区平均得分仅为0.344 8;发展不平衡、软实力不足是制约当前发展最重要的2个因素;提出相关的工作建议可为优化基层科普工作布局、提高工作实效提供有益参考。     

基于模糊评价的VDT系统搜索策略绩效形成机理研究

为优化视觉显示终端（VDT）结构性搜索界面的布局,提高作业绩效和安全,设计了VDT系统搜索实验,构建了搜索目标位置在4个主观偏好指标下的Pythagorean模糊集决策矩阵,运用交互式多准则决策（TODIM）法计算各目标位置偏好的总体优势度并排序;同时对VDT系统搜索实验中各目标位置的绩效进行方差分析并排序,分析系统搜索策略下作业者对目标位置的主观偏好与绩效之间的关系。研究结果表明:基于系统搜索策略的VDT作业绩效在不同目标位置差异显著;导致绩效差异的根本原因是作业者对搜索目标位置的主观偏好度,而不是搜索目标的位置属性;除中心区域外,偏好度高的区域搜索绩效要优于偏好度低的区域。

Exploration of Science Parks

Abstract

Science parks have developed greatly in the world, whereas empirical researches have showed that science parks based on linear model cannot guarantee the creation of innovation. Hi-tech innovation is derived from flow and management of information. The commercial and social interactions between in-parks and off-park firms and research institutions act as the key determinant for innovation. Industrial clustering is the rational choice for further developing Chinese science parks and solving some problems such as the lack of clear major industries and strong innovation sense, etc.

Indonesia’s Accidental Island: Composing the Environment in the Echo of Disaster

By presenting stakeholders’ competing representations of an extraordinary geological formation, an island with a surface that is comprised of runoff from an infamous mud volcano in East Java, this article explores the communicative openings and closures that arise during an environmental disaster. A particular concern is attuning communicative practices to the diverse human and nonhuman actors that not only produce disasters but also shape our understandings and responses to disasters. Drawing on the work of Bruno Latour, this article suggests that non-anthropocentric modes of inquiry present new communicative and political possibilities for pursuing both social justice and safe environments. While this article focuses on a specific set of incidents in Indonesia, this project develops tools and perspectives that can be applied to environmental conflicts at other places.     

Between Active Seekers and Non-Users: Segments of Science-related Media Usage in Switzerland and Germany

ABSTRACT

Citizens’ attitudes toward science are related to their use of science-related information from various sources. Evidence is scarce regarding citizens’ individual media repertoires for staying informed about science as segmentation studies so far have primarily focused on scientific attitudes. In this paper, we explore audience segments regarding their science-related information behavior and whether such segments are comparable or vary between two countries with similar information environments. Based on two surveys in Switzerland and Germany, we identify national audience segments that differ in their science-related information repertoires, and analyze their sociodemographic characteristics and science-related attitudes. In both countries, we find very comparable information user segments ranging from those who inform themselves frequently about science (“Active Seekers”/“Science Consumers”) to those who hardly get in contact with any information about science and research (“Non-Users”). Those segments which get in contact with information about science frequently show generally more positive attitudes.     

Exploration of Science Parks

1 DEVELOPMENT OF SCIENCE PARKSThe concept of science park originated in the US. Manyterms are used to describe science parks, such as researchpark, technology park, science centre, research centre,innovation centre, and with various combination of these(MacDonald, 1987). The first science park in the worldis Stanford Industrial Park established in 1951. In 1955,only seven companies were located in the park. By 1980there were ninety companies including Hewlett PackardCompany, whic…     

基于整体开发管理的国际河流决策支持系统

基于国际河流开发管理的现状，分析国际河流整体开发管理理论的演进。得出整体开发管理决策实施的原则及思路：流域开发管理要以流域边界为界，将整个水系自然联系的区域作为不可分割的整体，进行统一权衡，突出共同利益，流域内开发与流域外开发相结合。以建立多层次的国际合作机构。对国际河流决策支持系统进行设计，即以国际河流流域为体系，各国国内流域测点为单元。国际流域综合协调委员会为决策支持中心、各国流域机构委员会为决策支持分中心。并研究系统的公用信息平台建设，信息开发、管理与维护。河流水资源、水环境实时监控等技术支持系统。实证分析澜沧江-湄公河流域决策支持系统的建设。并指出国际河流水资源的开发与管理，水权等问题有待进一步深入研究。     

基于文献计量分析的大数据驱动城市固体废物监管研究进展

利用文献计量学方法,对Web of Science核心合集数据库中2010—2020年大数据驱动固体废物监管的研究论文开展综述研究,通过对发文量、发文机构、出版物、关键词等文献指标统计分析,全面了解研究现状,掌握发展趋势,洞悉前沿热点,以期为推进城市固体废物信息化和智能化管理提供科学依据。研究发现:在检索时间段内发文数量呈逐年上升趋势,但总发文量相对较少,共计83篇,说明该研究属于新兴、前沿性的领域;发表载体主要包括期刊论文、会议论文和综述论文3种类型,论文主要在Sustainability、Journal of Cleaner Production和Waste Management等期刊发表,且引用频次较高;既有研究主要考虑数据工程和数据科学2个维度的应用,以实现固体废物全生命周期的节点管控,前者关注数据源获取以记录废物的流向与流量信息,后者通过对各类大数据进行建模分析,为提升固体废物管控效率提供决策支持。
