Ecological Mechanisms of the Formation of Biological Rhythms in Hibernators of the Family Sciuridae in Northeastern Siberia

A mechanism of the formation of biological rhythms in hibernators at cold temperatures is proposed. Certain ecophysiological characteristics have been studied in three hibernating species: the ground squirrels Citellus undulatus Pallas, 1778 and C. parryi Richardson, 1825 and the chipmunk Tamias sibiricus Laxmann, 1769. The changes in body temperature and the temperature of litter in wintering nests during hibernation seasons have been studied. The dependences of metabolic rate on ambient temperature and the size and species of animals have been studied.

可持续发展下的生态经济学理论透视

生态经济学是一门正在蓬勃发展的新兴交叉学科，可持续发展是生态经济学研究的中心问题。人类对可持续发展问题的极大关注推动了生态经济学的发展。本文从宏观角度分析了可持续发展问题的凸显和生态经济学的兴起，着重指出生态经济学是关于可持续发展的科学的认识；阐述了可持续发展条件与状态的生态经济学理论内涵；论述了生态经济系统的本质特征及其可持续发展评估的核心内容；概括了可持续发展评估与绿色国民经济核算的框架及其目标和衡量方法。     

矿山清洁生产示范研究

矿山清洁生产具有双重性。矿山生命周期决定了矿山清洁生产体系的特殊性。矿山清洁生产体系是由培训体系、生命周期清洁生产体系和监合与审核体系构成的一个系统，生命周期清洁生产体系包括从资源勘探-规划设计-开发-闭矿-后续土地利用与监测的各个阶段。与其他行业相比，矿山清洁生产难度大且明显滞后，开展矿山清洁生产示范研究势在必行。     

江苏省环境与人口、经济的协调发展分析——基于环境安全视角

协调发展既是国民经济乐观发展的客观要求,同时也是人类可持续发展不可或缺的组成部分。江苏省协调发展问题的研究有利于解决环境问题的定位,发现环境发展中的薄弱点与发展潜力,促进环境与人口、经济的协调发展。以环境安全理论为依托,以强调协调发展为出发点,建立江苏省环境与人口、经济系统的协调发展指标体系,应用改进的层次分析法（AHP）及变异系数法权重均值赋权,借鉴模糊数学中隶属度函数来计算协调系数。结果表明：2001~2010年江苏省环境与人口、经济系统的平均协调水平处于基本协调状态,并且有稳中上升的趋势,协调发展前景乐观;同时分析并提出了建立健全江苏省协调发展机制、探讨环境安全维护体系建设、制订缓解人口压力政策等建议

公众环境意识与可持续发展关系初探

目前,国内存在的各种环境问题,归根到底是由于发展战略的不同所致,人们开始重新去认识和评价传统发展战略的局限性,标志着人类文明即将步入一个被称之"环境文明"新的历史时代.历史文化传统和经济发展水平决定公众环境意识,公众的环境意识直接影响可持续发展战略的实施,如何增强,提出决策和建议,通过大力开展环境宣传教育,提高公众环境意识,可持续发展,实现可持续发展的战略.     

The application of the psychological contract to workplace safety

INTRODUCTION: Psychological contracts of safety are conceptualized as the beliefs of individuals about reciprocal safety obligations inferred from implicit or explicit promises. Although the literature on psychological contracts is growing, the existence of psychological contracts in relation to safety has not been established. The research sought to identify psychological contracts in the conversations of employees about safety, by demonstrating reciprocity in relation to employer and employee safety obligations. The identified safety obligations were used to develop a measure of psychological contracts of safety. METHOD: The participants were 131 employees attending safety training sessions in retail and manufacturing organizations. Non-participant observation was used to collect the data during safety training sessions. Content analysis was used to analyze the data. Categories for coding were established through identification of language markers that demonstrated contingencies or other implied obligations. RESULTS: Direct evidence of reciprocity between employer safety obligations and employee safety obligations was found in statements from the participants demonstrating psychological contracts. A comprehensive list of perceived employer and employee safety obligations was compiled and developed into a measure of psychological contracts of safety. A small sample of 33 safety personnel was used to validate the safety obligations. CONCLUSIONS AND IMPACT ON INDUSTRY: Implications of these findings for safety and psychological contract research are discussed.
