Finances and Well-Being: A Dynamic Equilibrium Model of Resources.

This study of 513 Dutch farmers tested a dynamic equilibrium model of resources (an extension of the conservation of resources theory; S. E. Hobfoll, 1989, 1998, 2001). With structural equation modeling, the advantages of a 3-wave longitudinal design were comprehensively used, such as addressing bidirectional causal effects and within-individual vs. between-individual change. This allowed for a careful analysis of the management function of resources in the stress process. Results showed that well-being had stronger within-person stability than finances. Increased levels of financial problems temporarily increased psychological distress but not self-reported illness. Conversely, farmers with higher stable baselines of psychological distress also had higher baselines of self-reported illness and experienced more negative changes in their financial situation.

Wind energy resource assessment for five locations in Saudi Arabia

The analysis of recently collected wind data at five sites in Saudi Arabia namely, Dhulum, Arar, Yanbu, Gassim and Dhahran is presented. The five sites represent different geographically and climatologically conditions. The data collected over a period spanned between 1995 and 2002 with different collection periods for each site. Daily, monthly and frequency profiles of the wind speed at the sites showed that Dhulum and Arar sites have higher wind energy potential with annual wind speed average of 5.7 and 5.4 m/s and speeds higher than 5 m/s for 60 and 47% of the time, respectively. The two sites are candidates for remote area wind energy applications. The costal site's, i.e. Yanbu and Dhahran wind speed data indicated that the two sites have lower annual wind speed averages and wind blows at speed higher than 5 m/s during afternoon hours. That makes the two sites candidates for grid connected wind systems for electrical load peak shaving. The data of Gassim site showed that the site has the lowest wind energy potential compared to the others. The annual energy produced by a Nordex N43 wind machine is estimated to be 1080, 990, 730, 454 and 833 MWh for Dhulum, Arar, Yanbu, Gassim and Dhahran, respectively. The analysis showed that the estimated annual energy produced by the machine based on 10 min averaged data is 2.5% higher than the estimated energy based on 30 min averaged data.     

大藤峡水利枢纽及在珠江防洪与水资源综合利用中的地位与作用

大藤峡水利枢纽是珠江流域西江干流上的控制性水利枢纽工程，在流域防洪及水资源方面具有不可替代的作用，同时具有发电、航运与灌溉等综合利用效益。国务院在对《珠江流域防洪规划》的批复中要求抓紧做好前期工作．积极促进大藤峡水利枢纽建设。本文对大藤峡水利枢纽及在珠江防洪与水资源综合利用中的地位与作用进行了简要的介绍。     

三江平原水利综合规划的重新编制问题

三江平原是我国重要的商品粮基地和粮食战略后备基地。原有规划距今已过30年，远不能适应现代发展要求。结合新的形势，提出了重新编制三江平原综合规划的现实意义、目标设想及主要修编内容。     

水资源综合利用与管理规划初步研究

通过对水资源可持续利用规划进行的宏观、中观、微观三个层次的研究提出了管理规划的模型．利用该模型，可通过对环境经济的评价促进我国社会经济可持续发展目标的实现．本研究从加强水资源管理，重点要从水资源产权管理、水资源开发利用规划以及水资源合理配置几方面着手，提出应建立健全水资源管理的法律、政策和协调机制，加大水价改革力度，提高水价对促进水资源合理利用的经济杠杆作用，促进水资源的可持续利用．

水生生物环境诊断(AOD)技术应用研究

介绍一种新型的毒性试验方法——水生生物环境诊断(AOD)技术，该方法将冷冻浓缩和生物测试技术有机地相结合，较好地解决了低毒性水体的毒性测试问题。应用本项技术以红鳍鱼为受试生物，分别对湖北武汉马伧湖、墨水湖、广东深圳河、长江干流寸滩等几个断面、丹江口水库白河、丹江河口、老灌河等不同水体进行AOD测试，所得48hr-LC\-50结果与实际水质状况基本相符。     

当前水价改革中迫切需要注意的问题

加强水价改革，提高水价，促进节约用水，已经成为全社会关注的焦点。在节约用水和水资源优化配置条件下如何确定水价，水价构成及供水企业的合理成本与利润，以及资源水价的分配和用途是当前水价改革中亟须研究探讨和重视的问题。商品水价应该包括三个部分：一是资源水价，二是工程水价，三是环境水价。只有包括资源因素的水价，才能真正发挥水价在水资源的优化配置和合理利用方面的调节作用。
