The Interstate River Compact as a Water Allocation Mechanism: Efficiency Aspects

Interstate river compacts are widely used to allocate water among riparian states. Twenty-one compacts are currently in force in the western United States, and these compacts are mostly of two types: those that allocate a fixed amount or flow of water to individual states; and those that allocate percentages of available water to the riparian states. This study compares the performance of the two resulting allocations with that resulting from basin-wide optimization without compact constraints. While widely varying hydrologic and economic characteristics of river basins create a large set of possible outcomes, a range of stylized case studies indicates that percentage compacts are likely to generate greater net benefits and to result in more equitable risk-sharing than fixed compacts under many circumstances. In light of recent compact negotiations in the southeastern United States, it is recommended that efficiency analyses under present and future conditions be made a part of all compact negotiations.     

红河油田长8储层的地质特征

红河油田长8储层含油气丰度低、渗透率低,纵向和横向上均质性差。通过对沉积微相的研究对比,认为水下分流河道及河口坝砂体是构成该区域有利储层的相带。     

基于相关与偏相关分析的城市居民休闲度假市场开发研究——以南京为例

我国旅游业正向休闲度假型转变。运用相关分析与偏相关分析方法,以南京为例探析城市居民休闲度假旅游需求。研究发现偏爱休闲度假的居民由于地位与收入的不同在旅游资源喜好、旅游活动偏好、购买行为、信息来源渠道、出游方式等方面与一般居民有着明显差异。因此,休闲旅游目标市场的定位应在高学历、中高收入阶层,旅游资源的开发应优先考虑湖泊水滨、森林山地,产品开发应注意项目与资源的耦合且促销渠道应以网络为主,兼顾传统媒介。     

珠三角地区区域间创新差异及创新活动的位序规模分布实证研究

本文借助增长周期的理论框架并运用创新申请授权量和受理量作为指标,对珠三角地区九个城市近十年来的地区间创新差异及创新活动的位序规模分布进行了实证研究。通过计算比较和回归分析发现,增长周期的阶段性变化和潜在的内生增长因素对珠三角地区的区域创新发展都产生了影响。     

黑龙江挠力河国家级自然保护区环境教育现状与发展对策

环境教育是实现保护区资源保护的一种有效途径,虽然在挠力河自然保护区内开展过相关的环境教育,但形式单一、不成规模。通过对游客进行问卷调查,可见游客对保护区开展的环境教育满意度不高,感知程度并不明显。基于对环境教育开展情况的相关调查的结果,提出针对挠力河自然保护区的环境教育对策。     

江苏河蟹消费特征研究

江苏河蟹产业不论是在产业竞争力还是在产业规模上,都处于全国领先水平。论文通过问卷调查相关消费者,分析了消费需求情况,进而得出江苏省河蟹总体消费特征,最后从发展保鲜技术、规范交易市场、采用适宜的包装、加强河蟹品牌与生产地的联接、生产产品注重差异性五个方面提出了发展江苏河蟹产业的建议。     

浅谈当前我国能源形势与能源安全战略

我国能源发展现状：分布区与消费域性矛盾突出;能源消费加速增长,供给不断增强,但对外依存度加大;能源科技装备水平大幅提升;国际合作加快,多元化进口格局形成;体制机制改革稳步推进。面临问题：资源紧缺问题严重;煤炭、石油等传统能源仍是我国的基础能源,应对污染和气候变化问题突出;国际能源形势复杂多变,利用境外能源资源面临巨大挑战;清洁能源所占比重很小,能源结构调整任重道远;能源价格机制尚需完善,体制改革有待深化。建议：积极做好节能减排工作;国家增强能源保障能力;国家最大优化能源结构;加快能源科技自主创新;积极扩大能源国际合作;健全法律法规,加强战略规划和体制改革。     

Process,goal, and social interaction differences in recreation: What makes an activity substitutable

Abstract

In the present study two recreational activities, deer hunting and goose hunting, both similar in form, are compared. The study shows that the activity with the fewest perceived substitutes, deer hunting, also showed higher mean ratings on items measuring the importance of various elements of the experience, such as the process of participation, the goal of the activity, and the social interaction that accompanies the activity by the participants. Deer hunters also reported greater participation in the activity by peers and were more likely to be introduced to the activity by a family member. It is argued that these differences in the importance of the elements of the experiences influence the perceived substitutability of a recreational activity.     

The Potential of Interdisciplinarity for Leisure Research

Abstract

Knowledge about preferences for campsite attributes is needed so that management strategies can be guided by users’ preferences for settings and experiences. However, results of campsite choice studies have shown great variability across settings. Reexamination of this research shows a hierarchical typology of attributes: most important are necessity attributes, which supply basic camping needs, followed by experience attributes, which enhance preferred experience outcomes, and finally amenity attributes, which are relatively minor but can improve site quality. A survey of Whitewater boaters confirmed the predicted order of attribute importance and generally supported the proposed definitions of attribute types. A tentative model of campsite choice is offered in which sites are evaluated first for their ability to provide necessity attributes, then experience attributes, and finally, if more than one potential site remains, amenity attributes. Constraints may cut the evaluation process short anytime after the initial (necessity attribute) stage.
