This paper explores the importance of differential output growth across regions within a country in reducing the country's total carbon dioxide emissions from the combustion of fossil fuels. It proposes a framework that decomposes changes in emissions into sources attributable to 1) national growth rate of gross domestic product (GDP), 2) differential GDP growth across regions, 3) changes in energy intensity, and 4) changes in CO2 emission coefficient of energy. Data for China (1995-2009) and the United States (1990-2009) are analyzed. Uneven growth across regions reduced carbon dioxide emissions in both countries. © 2013 Elsevier Ltd. Source

This paper decomposes energy intensity change across countries into five components attributable to technological catch-up, technological progress and changes in capital-energy ratio, labor-energy ratio and output structure. It is found that (1) technological progress, capital accumulation and output structure change contributed to the decline of energy intensity from 1980 to 2010, (2) changes in labor-energy ratio drove up energy intensity, and (3) spatial and temporal heterogeneity existed regarding relative importance of the five components. © 2013 Elsevier B.V.

Minimum weight covering problems have played an important role in many real applications. In this paper, two typical minimum weight covering problems, namely vertex covering problem and edge covering problem, are studied under stochastic environments. According to different decision criteria, we propose three stochastic programming models: the expected minimum weight cover model, α-minimum weight cover model and the most minimum weight cover model. A hybrid intelligent algorithm that integrates stochastic simulation with genetic algorithm is designed to solve the proposed models. Finally, numerical experiments are performed to show the effectiveness and robustness of the proposed algorithm. © 2012 Elsevier Inc. All rights reserved. Source

This paper investigates the influences of stakeholders' power and corporate characteristics on social and environmental disclosure practices of socially responsible Chinese listed firms identified by a social responsibility ranking list. A stakeholder-driven, three-dimensional social and environmental disclosure index including disclosure quantity, disclosure type quality and disclosure item quality, is constructed to assess sample firms' social and environmental disclosures in their two public reports: annual reports and corporate social responsibility reports. Findings indicate that corporate social and environmental disclosures have significant and positive associations with firm size, profitability, and industry classification. The roles of various powerful stakeholders in influencing corporate social and environmental disclosures are found to be generally weak in China, except that shareholders have influenced corporate social and environmental disclosures and creditors have influenced corporate disclosures related to firms' environmental performance. © 2013 Elsevier Ltd.

The concepts of interval-valued states of rules, interval-valued state variable weights of rules and interval-valued variable weights of rules are proposed, and a new interval-valued fuzzy inference method, called IVVWSI (interval-valued variable weighted synthesis inference) method, is presented based on factor space theory. Furthermore, the analysis on response capability of fuzzy systems constructed by IVVWSI algorithms shows that such fuzzy systems are bidirectional interpolation approximators for unknown functions. © 2013 ISSN 2185-2766.
