欠发达城市人居环境评价体系构建及应用

在参阅国内城市人居环境评价指标体系研究的基础上，选择安徽省六安市为样区，提出了欠发达城市人居环境评价的原则、指标构成以及评价模式和方法。其中，指标体系共分为目标层、准则层、分类层和指标层4个层次，从居住建设、生态环境和社会经济三大系统构建了39个单项指标，依据六安市2005年的调查统计资料，对其人居环境的建设水平和满意度两方面进行了对比评价，验证结果科学可行，可为同类地区人居环境质量评价提供参考。     

混凝土结构施工中人因差错的模拟

以施工现场人因差错真实准确的调查实测数据为依据,笔者采用人的可靠性分析方法建立了混凝土结构施工中人因差错发生及其对混凝土强度影响规律的数学模型,并编制了相应的模拟计算程序。将该模拟计算程序所得的考虑人因差错的混凝土强度模拟计算结果与实测的混凝土强度调查结果进行比较,二者具有很好的一致性,说明该数学模型和模拟计算程序是比较符合实际的,也是比较合理的。上述模拟计算结果为考虑人因差错的结构安全性分析以及人因差错的有效控制措施研究提供了参考依据。

HUMAN BEHAVIOR AND RESPONSE TOWARDS STORM HAZARD IN WEST VANCOUVER,BRITISH COLUMBIA1

ABSTRACT: Human behavior and response towards storm hazard are examined in this study. One-hundred and twenty flood victims in West Vancouver, British Columbia, were administered a sentence completion test to ascertain how these victims behaved and responded to the flash flood of July 12, 1972. The sentence completion test consisted of 11 sentence stems. Seven of these dealt with the respondent's behavior toward the storm experience, and four with the issue of internal vs. external locus of control. Completions of the seven sentence stems at three time situations showed that West Vancouverites expressed the normal reactions of fear and anxiety before the storm; showed negative emotions during the storm; and displayed a feeling of mutual cooperation after the storm. Completions of the remaining four sentence stems revealed that West Vancouverites emphasized the importance of internal factors, viz., autonomy, drive and hard work, in controlling their lives. They recognized God as a benevolent - protective and almighty - powerful figure. Forty percent of the respondents did not believe in luck, while 8 percent regarded it as important in their lives. One might conclude that West Vancouverites could cope with natural hazardous threats better than those who rely on external factors in directing their lives.     

INTERNATIONAL DECADE ON DRINKING WATER AND SANITATION1

ABSTRACT: The UN conference on Human Settlements (HABITAT) held in June 1976 at Vancouver, Canada, concluded that nearly two-thirds of the population of the developing world lacked access to safe drinking water and that a larger proportion lacked the means for hygienic human waste disposal. The conference urged governments to give priority to these two areas in their developement process. In March 1977, the UN Water Conference, held at Mar del Plata, Argentina, called for establishing the 1980's as the Decade for Drinking Water and Sanitation. The goal would be to bring clean water and sanitation to all peoples in the world by 1990. Since March 1979, four separate UN bodies have passed resolutions supporting the Decade and calling on all governments to support the Decade's goals. The U.S. Government, other OECD member states, and the private sector must combine to make this Decade a success.     

POLITICAL PARTICIPATION AND WATER RATES: A REPLY1

ABSTRACT: Mercer and Morgan provide several valid criticisms of a previous analysis on political influence and water rates. More sophisticated statistical analyses may be justified given the high degree of interdependence among regulated firm variables. Theoretically, there are numerous measures of political activity superior to the one employed in the original analysis; however, data unavailability precludes their use. A better (and yet practical) measure of consumer leverage may be relative dominance by a specific political party. Until relatively easy access is obtained to municipal election data, the possible political variables that can be employed in more elegant analyses are few in number, and each has theoretical limitations.

Biospheric influence on carbon dioxide measurements in Italy

The study concerning carbon dioxide measurements taken during the 1997, 1998 and 1999 summer campaigns at two different altitude stations and biospheric conditions are presented. The higher station (Mt. Cimone, 2165 m a.s.l.) is characterised by 360° free horizon and is located on a rocky mountain while the lower (Ninfa lake, 1550 m a.s.l.) is located inside the red spruce and beech forest. The different behaviour of CO₂ at the two mountain stations has been registered. It shows the strong effect of nighttime soil emission and vegetation respiration on CO₂ mixing ratio increases and of diurnal vegetative activity on CO₂ concentration decreases at the lower measurement site. The baseline character of the higher measurement site has been confirmed by comparison of CO₂ diurnal amplitudes recorded at the two stations.     

Human Impacts on Drainages of the Mesa Central, Mexico, and Its Genetic Effects on an Endangered Fish, Zoogoneticus quitzeoensis

Abstract:  The Mesa Central of Mexico is of special conservation interest due to its high richness of freshwater fish species, of which the goodeines are one of the most representative groups. Through an integrated approach, we determined conservation priorities for goodeine populations. We based our recommendations on the genetic diversity (variation in five microsatellite DNA loci) in 10 populations of Zoogoneticus quitzeoensis and on an analysis of ecological (e.g., presence of exotic species), social (e.g., political situation), and environmental (e.g., pollution) information for 52 historical occurrence points for species in the genus Zoogoneticus . Patterns of genetic erosion and genetic diversity indices were closely associated with human impact. Recent bottleneck events were most evident in the populations from remnants of the lakes drained at the beginning of the twentieth century. We identified seven operational conservation units (OCUs), all of which should be conserved because they contain unique portions of the total variation of the species. Special attention needs to be given to increase genetic variability, recover population sizes, and reestablish contact among populations within OCUs. It is imperative to create an integrative and effective approach for the recovery and conservation of the freshwater fish diversity of Central Mexico that is based on social and natural sciences.
