SPRINGFLOW EFFECTS ON CHEMICAL LOADS IN THE SNAKE RWER,SOUTH-CENTRAL IDAHO1

ABSTRACT: The 150-kilometer middle reach of the Snake River (middle Snake) in south-central Idaho receives large quantities of water from springs discharging along the north side of the river from the regional Snake River Plain aquifer. Water-quality samples collected from nine north-side springs in April 1994 indicated that springs in the upstream part of the reach had larger concentrations of dissolved solids, dissolved nitrate, total nitrogen, tritium, and heavy isotopes of hydrogen and oxygen than to springs in the downstream part of the reach. Because the spring chemistry varies in the reach, discharge from the springs resulted in a degradation in water quality in some parts of the middle Snake and improvements in water quality in other parts. Depending on the annual discharge in the Snake River, the contribution from the north-side springs represented 33 to 66 percent of the discharge, 32 to 57 percent of the dissolved solids, 26 to 50 percent of the total nitrogen, and 7 to 14 percent of the total phosphorus transported annually from the middle Snake. Synoptic sampling showed that the north-side springs contributed 84 percent of the discharge and 35, 40, and 10 percent of the dissolved solids, total nitrogen, and total phosphorus load, respectively, to the Snake River during the peak of the irrigation season in 1994.     

Devolving power from the state: local initiatives for nature protection and recreation in Sweden

ABSTRACT

Quests for devolving more power to local actors for nature protection stem from both international and national policies. Also, there is a growing recognition of the need for local governments to promote green infrastructure for citizens to recreate and learn about their environment. Starting in 2004, the Swedish government has allocated special funding towards these goals through the Local Nature Conservation Programme (LONA). Virtually all Swedish municipalities have received such funding in pursuit of facilitating wide access to nature and promoting recreational activities, including the protection of nature areas, creating pathways, information devices, and promoting these areas among new societal groups to enjoy. This study presents the results of ten years of experience with LONA. A survey with respondents from 191 municipalities and 20 county administrations, together with 20 key informant interviews, show that the programme has been a success in several respects. Not only have most municipalities created a wealth of new ways to engage local organisations and citizens in nature conservation and recreation, but they have also broadened the ways they think about how nature is important to their constituencies. Due to innovative ways to count voluntary work as local matching of funding, smaller and less resourceful municipalities have also become engaged. Still, the local needs for further initiatives are deemed considerable. State support coupled with knowledge sharing is important to show policy priority to such bottom-up initiatives.     

Importance of public relations in recycling strategies: principles and case studies

The separate collection of waste, and especially of recyclables with specific collection systems, would not be possible without the involvement of the users. Apart from the physical installations such as collection containers, collection points, etc., the motivation of the users is an essential component. Motivation can be reinforced through public relations work. In addition to the underlying technical considerations, this paper describes the difference between communication in general and public relations and specifically examines public involvement in recycling. Through the use of examples, we look at the targeted users and typical media employed. Furthermore, we analyzes the development of public involvement. The examples show that public relations for recycling strategies relies to a great extent on attitudes, habits, and access to the target group. Thus, standardized procedures cannot be developed. For these reasons, public relation activities must be planned carefully and professionally and include an analysis of the target group, choice of media, and verification of success.     

计及消费领域的碳补贴政策演化博弈

考虑到企业和消费者的低碳策略往往受到政府补贴政策的影响,构建了消费者、消费领域相关企业和政府的三方演化博弈模型,探讨多种因素对各主体策略选择的影响机制.研究表明:企业低碳生产的概率与政府补贴力度、消费者低碳偏好、放弃低碳生产的机会成本和市场损失正相关,与生产方式转变成本负相关;消费者低碳消费的概率与政府补贴力度、低碳偏...     

关于事实劳动关系的研究

实践中存在着大量的事实劳动关系,而法律又未对事实劳动关系的概念、范围等问题作出明确界定。因此,有些事实劳动关系在审理实践中难以认定,为保护劳动者的正当权益,我们应当理清关于事实劳动关系的一些基本问题,并继续完善与之相关的法律制度。     

Post-Fordist transformation,the sustainability concept and social relations with nature: a case study of the Hamburg region

Following the United Nations Conference on Environment and Development, the concept of sustainability in general and of urban sustainability in particular has become increasingly significant in the course of the 1990s. Even if the environmental problems of cities are far from being solved, one can interpret this development as a change in the relationship between society and nature on both a discursive and a material level. At the same time the transition from Fordism to post-Fordism has given rise to new forms of urban entrepreneurialism, with an absolute priority to economic competitiveness on the one hand and sharpened social conflicts on the other. Looking at the case of the Hamburg region, the article discusses the interaction of these processes. Contrary to the understanding of sustainability as a broadly accepted policy goal it conceptualizes sustainability as a terrain of conflict. As such, we will argue, the sustainability concept and the underlying change in social relations with nature contribute to containing the contradictions of capitalist societalization, which in the transition to post-Fordism have become more visible again.

基于耦合关系的中国区域土地利用效益水平测度

新时期,土地利用的属性决定了土地利用能同时产生社会经济效益与生态环境效益,而这两种效益的交互耦合进一步决定了土地利用的整体效益。本研究建立了土地利用的社会经济效益与生态环境效益的耦合模型,设计了分别测度这两种效益的指标体系,用熵值赋权法计算了各指标的权重,进而计算了中国31个省(市、自治区)土地利用中这两种效益的系数及其耦合协调发展系数。结果显示:第一类地区是我国社会经济与生态环境均较好的上海市;第二类地区主要是社会经济发展较好但生态环境建设相对滞后的地区;第三类是生态环境较好但社会经济发展相对滞后的地区;第四类是社会经济发展相对滞后但生态环境建设更为落后的地区;第五类是生态环境建设滞后但社会经济发展更为落后的地区。最后,对每一个类型的成因和未来发展思路作了说明,在此基础上,又说明了中国土地利用的整体效益仍较为有限、整体效益表现出较为明显的区域分布特征、社会经济与生态环境的协调发展已成为提高我国土地利用效益的现实选择等基本政策含义。     

基于海湾空间的海洋经济差异分析——以辽东湾、渤海湾、莱州湾为例

以辽东湾、渤海湾、莱州湾为海湾地理空间尺度,引入泰尔指数和变差系数、灰色关联法研究三大海湾地区的海洋经济规模总量和海洋产业关联效应的差异,运用多种预测模型预测未来十年三大海湾间地区海洋经济对区域经济发展影响和贡献的差异。结果显示:三大海湾空间地区海洋经济差异呈现先增大后减小趋势,2007年后呈现协调优化发展趋势;滨海旅游业、海洋交通运输和海洋油气业、海洋交通运输和海洋渔业分别对应辽东湾、渤海湾、莱州湾三大经济区的拉动效应较大,形成各具区域特色的重要优势海洋产业;据模型预测结果分析,到2015年辽东湾、渤海湾、莱州湾地区海洋经济比重将分别达到34%、21%、25%;莱州湾、渤海湾的海洋经济直接贡献率分别平均以2%和1%的速度递增,而辽东湾则平均以0.1%的速度递减,到2020年辽东湾、渤海湾、莱州湾的海洋经济直接贡献率将分别为36%、29%、46%。     

工伤保险在社保制度中的排序变化及其内涵

目前我国常见的社会保险制度排序是养老保险、医疗保险、失业保险、工伤保险和生育保险,工伤保险制度位列第四位;而在计划经济时期的劳动保险制度系列中,工伤待遇规定曾位居第一位,尔后才是医疗待遇规定、养老待遇规定和生育待遇规定。上述排序变化的出现不会是立法者的偶然随意之为,而是以实行市场经济体制改革后我国劳动者-企业-国家之"三方关系"出现的根本性变化为背景原因的,与制度本身从一种面向牺牲了个人安全和健康的建设功臣们实施的国家慰谢待遇向以分散风险、损失共担为机理的保险制度发生的转化密切相关。针对近年来极端劳资纠纷事件增多的趋势,我国的劳动安全管理及工伤保险立法决策还应更加注重向弱势劳动者的倾斜。
