信息整合和数字图书馆的发展

信息整合技术的变迁从根本上改变了数字图书馆的运行模式,是推动数字图书馆技术发展的主要动力之一。后数字图书馆时代,数字图书馆已经演化成无所不在的知识环境。在这个泛在知识环境下,信息整合也提升为知识整合。知识整合是架构在信息整合基础上的新的服务层,是泛在知识环境的核心结构。语义网技术是实现知识整合的有效平台,尤其是本体技术是实现知识整合的基石。     

莫言与广西海洋文化有缘论

从电视剧本到小说,莫言为创作《红树林》,曾与广西海洋文化结缘。而这种缘分在作品中集中呈现为红树林与珍珠。作为广西海洋文化中精华所属部分,两者分别被作者匠心地赋予了一定的寓意和作用。由此,莫言的"结缘"的创作实践着实让人感受到了,广西海洋文化有幸得到文学层面"声扬"的同时,贴近生活成为实实在在的接地气之举。但是,本土当代文坛中的"新概念化倾向"却与之大相径庭。有鉴于斯,从生活出发是文艺创作活动的根本起点之理,也就不能惯常地被视为俗而又俗的老生常谈的论调。而这,正是莫言与广西海洋文化有缘之价值意义之所在。     

基于公共服务的海上旅游发展问题研究——以青岛市为例

海上旅游具有重要的经济价值、社会价值和个人价值,是我国滨海城市竞相发展的新兴产业部门。青岛市虽然在海上观光和游艇等项目上取得了一定的进展,但基础设施较薄弱、产品体系不够完善、管理尚不到位、专业人才缺乏等问题还比较突出。对此,政府可在＂公共服务＂上着力,应加强海上旅游基础设施建设,完善海上旅游产品体系,提升海上旅游的管理水平,完备海上旅游营销系统,保护海洋生态环境,培养海上旅游人才,以推动青岛市海上旅游业持续健康地发展。     

An evolving Learning Management System for new educational environments using 2.0 tools

The tools used in learning processes are in a continuous state of flux. One of the most significant changes is the application of Information and Communications technologies (ICTs) to educational contexts. This provides new possible ways to carry out learning activities, new learning services, the possibility to use new kinds of contents and activities, etc. However, ICTs have not provided as many advantages as they were supposed to, so changes are necessary. In this context, a new set of tools, Web 2.0, offers a new way to understand the Web, in which the user is the centre. Further, users can cooperate in order to define contents. This concept is also applied in technology-mediated learning but there are important problems when one tries to integrate such tools and concepts with existing systems. This paper explores the integration of these tools in traditional learning environments, the various possibilities and their advantages and drawbacks. After that, an interoperability scenario is described and two experiences are presented to show how 2.0 tools can be integrated in learning activities, and its effect in educational process.     

Research results of two personal learning environments experiments in a higher education institution

This paper focuses on institutionally powered personal learning environments (iPLEs). The concept of the iPLE can be seen as a way universities can incorporate learner-centred approach into the architecture of their technology-enhanced learning environments. The aim of this paper is to pose that there are other ways to learn complementary to virtual learning environments, such as using distributed Web 2.0 tools from personal learning environments (PLEs). With that aim in mind, this paper presents an exploratory study with two different iPLE configurations, analyses how they modify the learning–teaching process, and reports their perceived usefulness from the students' point of view. These two case studies were carried out by a research group of educational technology from a Spanish university in graduate and postgraduate courses. As reported by other case studies, the results revealed that students use the environment basically in the academic context and this usage is conceived as another time and effort requiring task. This fact can be observed in the low level iPLEs customization. The overall conclusions we can extract are, on the one hand, that the new environment to integrate informal and formal learning should be flexible and adaptable to the student's needs and preferences and, on the other hand, that academic tools might someday become personal tools.     

“中国梦”视角下加强大学生海洋权益教育路径之探讨

近年来中国与周边国家的海洋争端越来越多,但我国公民的海洋意识薄弱,尤其是大学生对海权意识的认识淡漠。如海洋的国土意识淡薄、缺乏正确的海洋权益意识观、海洋维权意识不强,对国家安全意识不到位。为此,在高校国防教育中应加强当代大学生海洋权益教育。

Environmental stress model for evaluation of vessel traffic in ports and waterways

Environmental stress model is proposed as an effective tool to the analysis and evaluation of navigational safety in ports and waterways. Marine traffic simulations are carried out in a virtual port area with various arrangements and conditions. Calculations of stress values and traffic volume criteria are illustrated. The simulation results provide a valuable hint for safety management of vessel traffic. The model provides quantitative information and helps administrators in decision making to achieve desired safety level and improve the efficiency of vessel traffic in ports and waterways.     

沿海省区发展海工装备制造业的潜力评价研究

海洋资源、空间争夺日益激烈,海工装备制造业成为各沿海国家及地区的战略性支柱产业。广阔的市场前景和有利的政策支撑下,我国沿海省区掀起海工装备基地建设热潮。以我国沿海省区为研究对象,从市场需求、相关产业和发展环境支撑能力三个方面构建了海工装备制造业发展潜力评价模型及评价指标体系,运用AHP和相关系数赋权法对其海工装备制造业发展潜力进行评价。结果表明:各指标与产业发展潜力的相关程度存在较大差距,改善产业发展环境可以有效提高产业的发展潜力;各省区发展海工装备制造业的潜力来源各有侧重,突出地区优势有助于协调区域资源配置实现产业快速健康发展;运用K-均值聚类分析,将沿海省区按照发展潜力划分3个等级有利于地区产业发展途径的选择。
