User-Centred Time Geography for Location-Based Services   总被引:4,自引:0,他引:4  
Location‐based services assist people in their decision‐making during the performance of tasks in space. They do not consider the user's individual preferences, time constraints and possible subtasks to be performed. In order to account for these important aspects, a user‐centred spatio‐temporal theory of location‐based services is required. We propose such a theory by combining classical time geography with an extended theory of affordances. It assumes that affordances belong to three realms: physical, social‐institutional, and mental. In addition to covering the capability, coupling and authority constraints from time geography, this allows for a user‐centred perspective because affordances describe action possibilities with regard to a specific person. Furthermore, the integration of mental affordances offers the possibility to account for cognitive time constraints due to the duration of decision‐making processes. This new theory for location‐based services is closer to the individual user and more plausible with respect to their daily lives. A business traveller scenario is used as a case study to demonstrate this.  相似文献

作为历史经济地理学的重要分支,历史货币地理研究迄今未引起学术界的充分关注。围绕历史货币地理研究的理论体系进行建构,无疑是非常有意义的尝试。我们对历史货币地理研究的对象、具体内容、与其他学科的相互关系、研究方法等问题进行了理论探讨,并提出了开创中国历史货币地理研究的建议,主张对先秦以来中国货币制度中长期存在的货币地域性问题进行全面而系统的研究。  相似文献

Professor Kovalev, a specialist in rural settlement, proposes the development of two new branches of economic geography in the Soviet Union that would be concerned with the study of regional differences in consumption and services. The proposal reflects the increasing concern of the Soviet party and government for raising the living standards of the population. Kovalev discusses a number of methodological problems, such as the availability of data.  相似文献

<正>一引言文献的匮乏长期以来制约着传统历史地理学科的良性发展(1),加上历史地理文献往往归属在其他文献类别之下且零落、分散,研究者搜集历史地理资料的过程往往需要花费更多时间和精力(2)。以竞争、创新为核心的新科研机制更使得传统历史地理学科受到严峻挑战(3)。近年来各国政府缩减人文学科研究经费,对研究的社会、经济意义作出诸多硬性规定,很多历史地理研究因不能产生显著的即时  相似文献

UK geography departments are now reaching the stage where, in light of social change and growing competition for students, the need to offer a degree programme that is relevant to the needs and expectations of students is a real urgency. Drawing on the People's Geography Project, an initiative from the USA, this paper details the experiences of the author in teaching relevant geography in first-year undergraduate tutorials. The paper contends that by providing an opportunity for students to engage in contentious debate and to adopt a political position, students are encouraged to approach issues from a critical geographical perspective, demonstrate the relevance of a geographical perspective in contemporary issues, recognise the conflicting interests from competing discourses and reach a possible, just solution to social problems. This paper reports on the choice of topics, the forum of debate and assessment through alternative coursework styles, and it analyses the learning of both geographical and transferable skills through a People's Geography tutorial programme. The degree of relevance perceived by both the students and the tutor is evaluated, and suggestions are made for further development of a People's Geography approach.  相似文献

The Human–Environment Research Observatory (HERO) Research Experience for Undergraduates (REU) program aimed to develop the next generation of researchers working on place-based human–environment problems. The program followed a cooperative learning model to foster an integrated approach to geographic research and to build collaborative research skills. The program hosted 12–16 students annually, who first engaged in an intensive short course and then formed three- or four-person teams to conduct research in four biophysically and socioeconomically diverse places. The teams used cyberinfrastructure to collaborate and integrate their research and findings. Most of the REU students have opted to attend graduate school and specialize in human–environment research.  相似文献

新修清史《地理志》的学术理论与编纂实践   总被引:1,自引:0,他引:1  
今天新修清史,继承历代纂修正史的传统,设立的<地理志>是不可或缺的重要组成部分.<地理志>将在充分利用各种史料、吸收现有清代地理志书成果基础上进行,充分借鉴历代正史地理志优点,全面反映有清一代疆域、政区、山川、关隘、土贡等地理要素的沿革和变迁,从而不仅可望超越<清史稿·地理志>,而且可以、并且能够达到二十一世纪初清史地理研究的新水平.  相似文献

The author, an opponent of Anuchin's views, charges that the discussion around the theory of a unified geography has been diverting the attention of the Geography Faculty of Moscow University away from practical tasks contributing to the growth of the national economy. Vol'skiy restates the Marxist theory of economic geography and calls on economic geographers for more constructive contributions to Communist economic development.  相似文献

Anuchin takes the discussion on methodology, long confined to the academic journals, to a general newspaper, complaining that geography as such in breaking up into particular disciplines without a reverse trend toward synthesis. He accuses I. p. Gerasimov, director of the Institute of Geography, of slighting research in integrated geography and economic geography and of reducing all geography to the physical-geographic group of disciplines.  相似文献
