促进节能减排的非线性四轮驱动分析——以浙江省为例

文章通过对浙江省能源资源、经济社会发展等方面统计数据的系统分析,提出了依靠能源结构、产业结构的双重优化、调整,节能减排技术、管理水平的运用、提升,以提高全社会的能源利用效率、减少污染物排放,进而实现浙江经济-能源-环境协调发展的思路,从而促使“线性的、数量驱动”的经济社会节能减排向“非线性的、全方位质量驱动”的方向发展。     

基于PSR模型的北京市西北生态涵养区生态健康评价研究

研究目的:作为保障首都生态环境质量与可持续发展的关键区域,北京市西北生态涵养区的生态健康程度反映了生态文明战略部署下首都高质量发展的综合成效。本文通过构建北京市西北生态涵养区健康评价指标体系,评价该区域的生态健康程度,为生态涵养区的可持续发展提供对策建议。研究方法:PSR模型、层次分析法(AHP)。研究结果:(1)基于PSR模型构建的生态健康评价指标体系包括压力、状态和响应系统3个准则层和10个评价指标,涵盖涵养区自然生态和人类活动影响;(2)研究区4个时段的健康指数分别为0.673、0.664、0.650、0.687,生态健康等级为一般。研究结论:北京市西北涵养区生态健康状况较为稳定,在保持西北涵养区建设现有成果的基础上,需要加大生态建设的力度,进一步提高生态健康水平。     

政府补贴下考虑企业环保努力的闭环供应链决策分析

在消费者具有环保意识的背景下,分析有无政府补贴时制造商环保努力对各节点企业价格、需求、利润等决策的影响,并进一步探讨补贴在各类最优策略中的作用。研究表明：环保努力能提高两类产品销售价格、扩大新产品需求,但对再制造品需求无影响;存在最优环保努力水平,使无政府补贴下制造商及系统整体利润最大;一定范围内补贴能遏制环保努力导致的再制造品销售价格上升,但对新产品价格无影响,且对零售商来说高补贴未必能带来高收益;消费者环保意识和制造商环保努力可以通过政府补贴影响产品需求和企业收益。     

文化保护视角下的旅游工艺品开发探究

旅游工艺品是旅游业中对文化资源进行商业化开发的方式之一。在开发过程中必然会出现当地传统文化与现代文化以及外来文化之间的涵化现象。旅游者虽然追求文化的真实性,但他们并不苛求文化的原形。而文化商品化虽然可能会使旅游工艺品有失去文化真实性的危险,但如果能处理好文化涵化问题,旅游工艺品则可成为传承和发扬地方文化的有力工具。旅游工艺品开发应在对当地文化元素保护的基础上,将传统文化和现代文化完美结合,走品牌化、特色化、功能多元化的开发与设计道路。     

职业延迟满足对员工过劳的影响研究——职业成长机会的调节作用

目前,员工过劳问题在我国企业发展中日益凸显,需要予以重视和解决。基于个体与组织互动角度,通过对338名企业员工的问卷调查分析职业延迟满足和职业成长机会对员工过劳的影响,并检验职业成长机会对职业延迟满足影响员工过劳的调节作用,结果表明：职业延迟满足的两个维度（工作延迟满足和职业生涯延迟满足）均对员工过劳有显著正向影响,而职业成长机会对员工过劳有显著负向影响;职业成长机会对职业延迟满足影响员工过劳具有负向调节作用,即职业成长机会越大,职业延迟满足与员工过劳的正向关系越弱。因此,企业管理者应合理引导和帮助员工做好职业生涯规划,为员工提供合适的多元化发展通道,以有效预防和缓解员工过劳。     

Evaluating ecotourism: The case of North Sulawesi, Indonesia

Ecotourism can contribute to both conservation and development and involves, as a minimum, positive synergistic relationships between tourism, biodiversity and local people, facilitated by appropriate management. This paper applies a framework for the development and evaluation of ecotourism to three protected areas in North Sulawesi. Due to its spectacular endemic biodiversity, the potential for providing quality nature experiences in North Sulawesi is high and tourism development is occurring rapidly. Site-level evaluations of ecotourism in three protected areas were performed to illustrate the application and the utility of the framework as a tool for evaluation and to assess the status of tourism in North Sulawesi. It is revealed that current relationships between people, resources and tourism in North Sulawesi have yet to provide the mutual benefits necessary for successful ecotourism. The approach and framework used to arrive at these conclusions have wide applicability for assessing the achievements of ecotourism at specific sites and for directing appropriate management strategies for ecotourism in protected areas.     

Predictors of individuals’ intention to conserve water in a lodging context: the application of an extended Theory of Reasoned Action

This study sought to develop an extended Theory of Reasoned Action (TRA) model to provide a clear understanding of individuals’ intention to conserve water in a lodging context. In particular, the extended TRA incorporates two additional constructs: environmental concern and water conservation activities in everyday life, into the original TRA model. The outcomes of the present paper have shown that individuals’ attitudes, subjective norms and water conservation activities in everyday life exert a positive influence on their intention to conserve water in a lodging context. The results also revealed that environmental concern has a positive influence on individuals’ attitudes and water conservation activities in everyday life but a non-significant influence on their subjective norms. The empirical results of Structural Equation Modeling (SEM) indicated that the extended model provides a better fit of the data, and explains greater amounts of variance in individuals’ intention to conserve water in a lodging context compared to the original TRA.     

谈计量工作是水泥生产中节能减排的重要手段

液晶电视动态LED背光源技术及其应用

目前LED的电光效率还不够高,亮度固定的LED背光源影响到显示图像的画质不能进一步提高,而且耗能发热而影响产品可靠性。本文研究的基于FPGA技术的分区动态控制LED背光源技术,其动态对比度特性明显的提高了液晶图像画质,大大的降低了液晶显示器(电视机)的实际使用功率,为提高画质和节能做出进一步的贡献。     

Tourism and conservation

Assessing the impact of tourism on environment is notoriously difficult, and is often hindered by emotional factors or considerations of private interest. Further, data on tourist movements and volumes, particularly on internal tourist movements, and on impact itself, are scarce. It is thus difficult to provide any overview of the environmental impacts of tourists, whether in one country or worldwide. This article examines these relationships so far as data allow, largely within the framework of the UK experience.
