Innovative solutions for averting a potential resource crisis—the case of one-person households in England and Wales

This paper seeks to test the hypothesis that growth in one-person households will increase the domestic consumption of energy, land and household goods in England and Wales. It concludes that if current consumer behaviour of one-person households persists there will be a significant increase in the consumption of all three resources in the future. However, it argues that that many opportunities exist in England and Wales for tackling this problem. For example the new housing programme, increasing ability amongst one-person households to afford “green alternatives” and the search amongst some one-person households for alternative lifestyles (which could be potentially more resource efficient). The paper suggests that providing one-person households with opportunities to live in more resource efficient housing and adopt pro-environmental behaviour could significantly reduce their future environmental impact. Various design, fiscal and awareness-raising solutions are presented in the paper and their viability is assessed. These include ecological homes, collective housing forms, occupancy tax, relocation packages, educational programmes and targeted advertising campaigns. The paper proposes that using a combination of these more innovative solutions to the problem could significantly reduce the future environmental impact of one-person households.

水资源对区域社会经济发展的支撑能力研究--以济南市长清区为例

水资源支撑能力即在当前技术水平条件下,某一区域水资源对区域发展总体目标的支撑限度.该文以系统动力学理论为指导,对长清区水资源的支撑能力进行了分析.拟定出在水资源约束条件下的三个区域发展方案,即:(1)水资源投资控制;(2)工业增长速度控制;(3)污水回用率控制.仿真结果分析表明,以方案(3)的适用性较好,在水资源投资不断增加,投资比例趋于合理的情况下,水资源对社会经济发展的支撑能力将由2002年的0.98提高天2010年的1.0.

Adapting the bioblitz to meet conservation needs

When conservation strategies require new, field‐based information, practitioners must find the best ways to rapidly deliver high‐quality survey data. To address this challenge, several rapid‐assessment approaches have been developed since the early 1990s. These typically involve large areas, take many months to complete, and are not appropriate when conservation‐relevant survey data are urgently needed for a specific locale. In contrast, bioblitzes are designed for quick collection of site‐specific survey data. Although bioblitzes are commonly used to achieve educational or public‐engagement goals, conservation practitioners are increasingly using a modified bioblitz approach to generate conservation‐relevant data while simultaneously enhancing research capacity and building working partnerships focused on conservation concerns. We term these modified events expert bioblitzes. Several expert bioblitzes have taken place on lands of conservation concern in Southern California and have involved collaborative efforts of government agencies, nonprofit organizations, botanic gardens, museums, and universities. The results of expert bioblitzes directly informed on‐the‐ground conservation and decision‐making; increased capacity for rapid deployment of expert bioblitzes in the future; and fostered collaboration and communication among taxonomically and institutionally diverse experts. As research and conservation funding becomes increasingly scarce, expert bioblitzes can play an increasingly important role in biodiversity conservation.     

国有高新技术企业核心资源安全策略研究

市场经济条件下,任何企业在运营中都存在着风险,高新技术企业面临的环境更具动态性和复杂性,其面对的运营风险也更为复杂。由于国有高新技术企业在资源获取、经营管理方面所具有的特殊性,其知识产权、企业文化、人才等核心资源已成为国有高新技术企业安全运营、保持持续竞争优势的必要条件,因此,针对国有高新技术企业现状,笔者围绕人力资源、知识产权、企业文化3方面的安全问题进行研讨,并提出相应的策略即包括实行知识产权保护制度、构建以人为本的企业文化、防止人才流失的管理层收购和股票期权策略。     

岫玉产业发展中的问题及经济学分析

岫玉产业是我国辽宁省岫岩满族自治县的特色产业和县域经济的支柱产业。由于岫玉产业生产原材料的稀缺性、独特性和不可再生性而成为国宝级的产业。近年来,岫玉产业的发展出现了过度开采、过度加工和无序竞争,导致岫玉产品贬值,盲目扩大产业规模带来了规模报酬递减。针对岫玉产业发展中的诸多问题,运用经济学的理论加以分析,提出岫玉产业可持续发展的政策性对策与建议。     

资源节约型社会评价指标体系的构建
