Measuring Enterprise Sustainability

Abstract: The purpose of this paper is to identify the key requirements for measuring enterprise sustainability. The paper argues that measuring enterprise sustainability requires the explicit consideration of a focal firm, its supply chain and the sustainability context within which the firm operates. Building on this notion, original definitions of enterprise sustainability and enterprise sustainability performance measurement systems (ESPMSs) are proposed. The definitions provide the basis for the development of a novel conceptual framework. The framework is used to identify seven key requirements and 35 associated sub-requirements for an ESPMS. Overall, the requirements highlight that sustainability performance measurement requires a systematic, structured and integrated approach that considers all aspects of enterprise sustainability. The framework presented in this paper is a conceptual model. In recognition of this point, the paper provides discussions on the potential application of the framework and guidance for further research. The academic, managerial and societal implications of the paper are also discussed. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment

Health effects, environmental impacts, and photochemical degradation of selected surfactants in water

Abstract: Surfactants are depended upon worldwide as cleaning agents. Their usage in such large quantities means that their waste and the potential for pollution are high. Many studies have been done over the last three decades encompassing treatment, alternatives to non-biodegradable surfactants, and the environmental impact. It has been found that although certain surfactants may not be directly toxic, when their concentrations are high in soil, they can act as agents to release toxic pollutants such as polychlorinated biphenyls (PCBs). The focus of this study is to review recent advances in the toxicology, the environmental fate, and the treatment of selected surfactants. In addition, photolytic and photocatalytic degradation of linear alkylbenzene sulfonate in water is presented.

Blacks’ Death Rate Due to Circulatory Diseases Is Positively Related to Whites’ Explicit Racial Bias: A Nationwide Investigation Using Project Implicit

Abstract: Perceptions of racial bias have been linked to poorer circulatory health among Blacks compared with Whites. However, little is known about whether Whites' actual racial bias contributes to this racial disparity in health. We compiled racial-bias data from 1,391,632 Whites and examined whether racial bias in a given county predicted Black-White disparities in circulatory-disease risk (access to health care, diagnosis of a circulatory disease; Study 1) and circulatory-disease-related death rate (Study 2) in the same county. Results revealed that in counties where Whites reported greater racial bias, Blacks (but not Whites) reported decreased access to health care (Study 1). Furthermore, in counties where Whites reported greater racial bias, both Blacks and Whites showed increased death rates due to circulatory diseases, but this relationship was stronger for Blacks than for Whites (Study 2). These results indicate that racial disparities in risk of circulatory disease and in circulatory-disease-related death rate are more pronounced in communities where Whites harbor more explicit racial bias.
