论潮汕近代民居建筑的海洋文化内涵

潮汕侨乡是广东侨乡的重要组成部分,华侨投资极大地推动了近代潮汕侨乡的建筑发展。近代潮汕侨乡建筑审美文化特征的主要表现是展现了中西建筑文化从接触碰撞到融会创新的历史过程,突出体现了开放性、兼容性、创新性的时代精神和审美特征。海洋文化对潮汕近代文化的影响是一个客现存在的事实,近代潮汕民居建筑文化是中国近代建筑文化的重要组成部分,有独特的历史文化价值,它给国际建筑思潮影响下的当代新地域性建筑的生存与发展以启迪。     

The City of Saskatoon’s Local Area Planning Program: A Case Study

The City of Saskatoon’s Local Area Planning (LAP) Program is a community-based approach to developing comprehensive neighbourhood plans. In order to achieve sustainable and implementable Local Area Plans (LAPs), the City of Saskatoon has been using innovative methods of collaborative decision-making to engage citizens. The program has been recognized nationally by the Federation of Canadian Municipalities for demonstrating innovative approaches to citizen engagement in Sustainable Community Planning. A total of eight LAPs have been adopted by City Council and 212 recommendations have been approved, with 101 of these recommendations being completed, 71 currently in progress and 40 to be determined. Great strides have been made to implement the LAPs by allocating resources for coordinating implementation, working with communities, and for implementing the various recommendations. In addition, over 1,000 people representing various interests have participated in one or more LAP Committee or implementation meetings. Through this participation, partnerships have been formed, program and service delivery has been improved, and most importantly, communities have taken ownership of their plans. After completing eight LAPs, the LAP communities, City Council and city planners have felt the need to measure ongoing changes and progress in the LAP communities. In recognition of this, the City of Saskatoon’s City Planning Branch will be working with LAP communities, the Community-University Institute for Social Research (CUISR) and other stakeholders to develop a framework for statistically measuring changes in LAP communities and to monitor “Neighbourhood Success Factors”. The Neighbourhood Success Factors will work to detect serious socio-economic conditions before they reach a point of crisis. This paper will first describe the LAP Program before reviewing the proposed framework for statistically measuring changes in Saskatoon’s neighbourhoods.

Some results on optimality in models with heteroscedastic errors from partial optimum designs

This paper studies optimum designs for linear models when the errors are heteroscedastic. Sufficient conditions are given in order to obtainD-, A- andE-optimum designs for a complete regression model from partial optimum designs for some sub-parameters. A result about optimality for a complete model from the optimality for the submodels is included. Supported by Junta de Andalucía, research group FQM244.     

中国股票市场价格波动特征分析

在股票市场中最令人捉摸不定,也最具有吸引力的是波动不已的股票价格。文章对中国股票市场价格波动的分析是从1997年9月展开至2002年10月,其间恰逢中国股市经历了一段从牛市的繁荣到熊市的萧条的过程,两种泾渭分明的市场氛围恰好提供了一个深入研究股票市场价格波动特征的有利契机。遵循经济控制论研究的思路,文章采用了理论分析、市场交易数据的实证研究等技术手段对中国股票市场价格波动进行了研究,通过运用经济控制论的方法建立理论模型,以上海股市和深圳股市的综合指数为样本,对中国股票市场系统本身的波动特征和稳定性进行了量化分析。     

India’s Social Development in a Decade of Reforms: 1990–91/1999–2000

The economic reforms initiated in India in 1991 have brought about visible upliftment of economic conditions of the country. This paper examines if the economic process is associated with an enhancement of India’s social development in equal measure in the reform decade of nineties. Ray (1989) considered thirteen social indicators of India and constructed the country’s social development index (SDI) as a certain weighted average of the selected indicators, for the years between 1950–51 and 1975–76. The present work broadly follows Ray (1989) in tracking the social development in the decade of economic reforms from 1990–91 to 1999–2000. The movement of SDI in nineties has been compared with the movements of India’s per capita income and plan expenditure on the social sector. The results show that though there has been growth in the social sector, it is not by far quite encouraging and perhaps more needs to be done in the social sector.

东北地区人口城市化水平的特殊性分析

20世纪末期,东北地区人口城市化水平达到50%以上,超过东北地区工业化水平,也超过全国人口城市化平均水平,但目前东北地区人口城市化明显存在着城市现代化基础相对薄弱,工业化发展动力不足的问题。东北地区人口城市化水平超前于区域经济社会发展水平的现象是我国区域城市化和工业化过程中的特有现象,其特征表现为:从发展趋势看,东北地区人口城市化增长速度放缓;从国内外比较看,东北地区人口城市化水平较高的优势已不复存在;从城市化质量指标看,东北地区城市经济总量和城市竞争力相对较低。东北地区的人口城市化虚高问题,在制定人口发展战略乃至实施国民经济发展规划中,尤其需要深入研究并认真加以解决。     

我国上市公司社会责任与企业价值关联性分析——以房地产开发与经营业为例

基于财务报告的指标体系、运用主成分分析的方法，对在我国深、沪上市的房地产开发与经营业公司企业价值（以托宾Q衡量）与所建指标体系之间的关系进行实证分析。分析结果表明：样本公司财务报告所反映的其社会责任履行情况与其企业价值相关关系显著，这一实证结果表明企业的社会责任履行对现代企业来说，已经不是一个可有可无的附属品，在企业生存和发展过程中发挥着越来越重要的作用。

Tree health mapping with multispectral remote sensing data at UC Davis, California

Tree health is a critical parameter for evaluating urban ecosystem health and sustainability. Traditionally, this parameter has been derived from field surveys. We used multispectral remote sensing data and GIS techniques to determine tree health at the University of California, Davis. The study area (363 ha) contained 8,962 trees of 215 species. Tree health conditions were mapped for each physiognomic type at two scales: pixel and whole tree. At the pixel scale, each tree pixel within the tree crown was classified as either healthy or unhealthy based on vegetation index values. At the whole tree scale, raster based statistical analysis was used to calculate tree health index which is the ratio of healthy pixels to entire tree pixels within the tree crown. The tree was classified as healthy if the index was greater than 70%. Accuracy was checked against a random sample of 1,186 trees. At the whole tree level, 86% of campus trees were classified as healthy with 88% mapping accuracy. At the pixel level, 86% of the campus tree cover was classified as healthy. This tree health evaluation approach allows managers to identify the location of unhealthy trees for further diagnosis and treatment. It can be used to track the spread of disease and monitor seasonal or annual changes in tree health. Also, it provides tree health information that is fundamental to modeling and analysis of the environmental, social, and economic services produced by urban forests.
