Analyzing Daqing＇s Urban Spatial Form Evolution： Basing on the Technology of RS and GIS

以我国目前最大石油城市——大庆市为研究对象,选取1984、1995、2007年3个城市建设关键时间节点,以Landsat MSS、TM卫星影像为主要数据源,利用GIS技术提取城市建设用地规模、形态、增长幅度、区位坐标等信息,计算城市空间扩张速度、强度、城市空间形态紧凑度、分维指数、城市增长理性程度等空间特征量,分析大庆市1984年以来城市空间扩张现象和特征,并结合经济社会统计相关数据及区域分析方法,探究其因果关系。研究认为,大庆市城市空间扩张与形态演化具有石油城市发展的典型性和一般规律,表现出建设用地总量大、扩张速度快、强度高、增量分布不均衡、空间形态不规则、紧凑度低、城市中心地迁移方向与用地扩张基本一致等特征。这些现象和特征的主要形成原因包括石油开发战略指向、自然环境约束、交通设施引导、城市规划调控、中心地功能变迁等五个方面。     

基于旅游的温泉文化遗产研究——兼论临沂汤头

文化遗产具有可敬畏性及匠心特征,旅游者通过对其观赏能够普遍获得很高的满意度。古温泉文化作为遗产旅游资源的一个分支,有待于做深入的具体研究。开展关于古温泉的文化旅游,有助于平衡现代大型地热温泉度假村的快速遍及现象。在给出温泉文化遗产概念和综述相关研究成果的基础上,主要以山东临沂温泉为例,就汤头、串汤降温、里汤与外汤、时间与季节汤等进行了较为详尽的内容挖掘,讨论了温泉与汤头的视角差异强调了古温泉水工范畴,指出温泉文化遗址公园、为教育功能的修复或复原、温泉利用应保证文化真实等有实践意义的开发方向。

Perceptions of pre-service teachers on seismic risk and their implications for science education: a comparative study between Spain and Portugal

Abstract

This study investigated the importance given by two groups of pre-service teachers of primary education from Spain and Portugal to seismic risk in a framework of different natural risks, both in personal terms and as future teachers. A questionnaire was used for data collection. Some questions about the seismic phenomenon were also included. The sample groups consisted of 110 students from an institution in Spain and 121 from one in Portugal. Both institutions are in cities affected by the historic Lisbon earthquake of 1755. The results showed that the risk of forest fire was the first choice for classroom study in both cases. The Spanish group was also more focused on the importance of other risks like flood and drought. The Portuguese group showed a greater concern with seismic risk, frequently referring to their own historic earthquake of 1755. A few gaps in knowledge concerning earthquake prediction and comparing seismic risk in different regions of their own countries were also found. In accordance with the results, it is suggested that training courses for primary school teachers should include Disaster Risk Education in Science Education for a better understanding of the impact of various hazards and a greater concern with seismic risk due to its particular features, especially in regions where the seismic pattern is characterized by long seismic cycles with major earthquake episodes.     

试析林木资产的计价入账方法

林木资产计价入账方法的选择是森林资源资产会计核算的重要问题之一。林木资产计价可供选择的方法主要有历史成本法和现行市价法两种,这两种方法各自有其适用条件、适用范围及优缺点,但相对而言历史成本法更为适合,因此,在对林木资产计价核算时应始终坚持能够用历史成本计价的尽可能用历史成本计价,不具备历史成本计价条件的再考虑用其他方法。

The grand tour: Sources and a methodology for an historical study of tourism

Research into the history of tourism is at an early stage of development. This article examines the range of source material which relates to the Grand Tour and considers the problems involved in its interpretation. It then outlines a methodology designed to investigate this area of tourism research.     

Never on Sunday? Mexican tourists at the beach

This paper examines contemporary middle class Mexican recreational tourism through a micro-ethnographic study of tourist behavior at a small beach resort in the state of Chiapas. Majority behavior represents the inversion of aspects of normal behavior, particularly in the deregulation of meal-times, night and day activities, and the rules for play. It is hypothesized that the particular, and comparatively excessive, behaviors described may stem from both the historically antecendant Spanish and Indian cultures, with their baroque tendencies, and from the recent liberation of the new middle classes from the “Victorian-like” rules of daily behavior. Behavior at the beach resorts resembles earlier types of vacation in the U.S.A. and this suggests there may be an evolution of tourist behaviors characteristic of the historical situation of the national home cultures of the tourists.     

The telecoms boom and bust 1996-2003 and the role of financial markets

Financial crises are still as much a part of the modern, information-and-communication-technology-based (ICT) economy as they were of previous economies. Why are we apparently unable to learn lessons from the past and avoid what Charles Kindleberger (2000) has called manias, panics and crashes? Why is it that our sophisticated stock of information, made readily and relatively cheaply available to us by our investment in ICTs, and our abundant theories and models, have not allowed us to steer clear of these financial excesses? The aim of this paper is to highlight some of the processes and mechanisms that have played a significant role in causing the Telecoms Boom and Bust, 1996-2003. The question of whether anything can be done about these processes and mechanisms in order to try and modify such financial excesses in the future is taken up in the conclusion.JEL Classification: A12, D8, E3, G1, L63, L96, N2, O30The author would like to acknowledge, without implicating, the helpful discussion with Richard Burns, Fred Bleakley and others who commented on an earlier version of this paper at Institutional Investors European Institute meeting in Berlin in March 2003, and with Stan Metcalfe on other occasions. In addition, thanks are due to many friends in NTT and InfoCom who assisted my learning about the Telecoms Industry and its dynamics.
