This article joins the continuing policy debate over the social responsibility of corporations, particularly in the mining industry. The author argues that the 'old school mining orthodoxy'—approaching the exploitation of mineral deposits solely from the technical and economic points of view—is long dead. Mining companies must also encompass the social dimension.
New policies for the mining industry are discussed in terms of recent worldwide trends and movements, e.g. globalization, economic interdependence and decentralization of governmental authority, and the rise of civil society as a political factor. These trends, together with the United Nations policies in quest of sustainable development and the consensus expressed at international conferences during the last decade, have deepened social awareness and set the stage for enhanced social responsiveness from the private sector. Socially responsible corporate policies include decentralization of decision-making to the field level, reaching out to stakeholders and shareholders, supporting governments which provide official development assistance for good governance and building broad partnerships to reduce social exposures.  相似文献

Methods to assess ecosystem services using ecological or economic approaches are considerably better defined than methods for the social approach. To identify why the social approach remains unclear, we reviewed current trends in the literature. We found two main reasons: (i) the cultural ecosystem services are usually used to represent the whole social approach, and (ii) the economic valuation based on social preferences is typically included in the social approach. Next, we proposed a framework for the social valuation of ecosystem services that provides alternatives to economics methods, enables comparison across studies, and supports decision-making in land planning and management. The framework includes the agreements emerged from the review, such as considering spatial–temporal flows, including stakeholders from all social ranges, and using two complementary methods to value ecosystem services. Finally, we provided practical recommendations learned from the application of the proposed framework in a case study.

This article presents a critical reflection on the theory and practice of social sustainability in the built environment, identifies areas of agreement and disagreement, explores theoretical and conceptual gaps and challenges, and suggests practical implications for future research and urban policy. It argues that despite revisionist approaches which challenge the tripartite structure of sustainable development, social dimension of sustainability remains an essential valid pillar. Utilising a qualitative meta-analysis methodology for undertaking critical analysis of previous research and publications on the topic, key themes of theory and practice of social sustainability are identified and critically examined. Accordingly, 10 key formative characteristics of social sustainability and their research and policy implications are introduced. The article concludes with institutional observations for policy-makers to achieve greater success in addressing largely underestimated dimensions of social sustainability in urban settings.  相似文献

As Green Corporate Social Responsibility spreads across the globe, the construction industry is under pressure to reduce the carbon emissions across their building projects. Between maximum profit and environment management, mathematical programming can be used as a decision support tool concerning the optimal green building projects portfolio. This environment strategic decision problem is addressed in this study where an activity-based costing decision model incorporating carbon tax costs and construction resources constraints is developed from the perspectives of capacity expansion and green technology outsourcing. The results illustrate the positive contribution of the mathematical programming approach to achieve viable green building projects portfolio solutions. Sensitivity analyses are carried out to analyse the impact of carbon footprint emission variation on maximum profit, and the corresponding results are discussed.  相似文献

Research shows that public commitment making helps promote pro-environmental behavior. However, not everyone may be willing to make such commitments. Therefore, it is important to investigate the conditions under which commitment making is likely to occur. We expected dispositional trust and situational expectations to determine the willingness to install a system of public commitments. Two studies are presented which show that group members low in dispositional trust (low trusters) are likely to choose for a public commitment system when their situational expectations concerning other group members' contributions are high, while those high in dispositional trust (high trusters) are likely to choose for a public commitment system when their situational expectations concerning other group members' contributions are low. It appears that for both low and high trusters the choice for a system of public commitments is instigated by a motivation to further the collective outcomes.  相似文献

The lack of knowledge regarding social diversity in the Wildland Urban Interface (WUI) or an in-depth understanding of the ways people living there interact to address common problems is concerning, perhaps even dangerous, given that community action is necessary for successful wildland fire preparedness and natural resource management activities. In this article, we lay out the knowledge and preliminary case study evidence needed to begin systematically documenting the differing levels and types of adaptive capacity WUI communities have for addressing collective problems such as wildland fire hazard. In order to achieve this end, we draw from two theoretical perspectives encompassing humans' interactions with their environment, including (1) Kenneth Wilkinson's interactional approach to community, (2) and certain elements of place literature. We also present case study research on wildfire protection planning in two drastically different California communities to illustrate how social diversity influences adaptive capacity to deal with hazards such as wildland fire. These perspectives promote an image of the WUI not as a monolithic entity but a complex mosaic of communities with different needs and existing capacities for wildland fire and natural resource management.  相似文献

This paper explores quantitatively Californians' interest in hybrid electric vehicles (HEV) based on a statewide phone survey conducted in July 2004 by the Public Policy Institute of California. The paper develops ordered choice models and factors that summarise beliefs about energy and the environment using principal component analysis. As expected, Californians concerned about the environment, energy efficiency, global warming and recent increases in the price of gasoline state a higher interest in hybrids; an even more important reason for considering hybrid electric vehicles, however, is the possibility of using high occupancy vehicle (HOV) lanes while driving alone, especially for people with potentially long commutes to work. The findings also suggest that beliefs about energy and the environment should be included in vehicle type choice models.  相似文献

We sought to understand why a social, desert rodent, the great gerbil, Rhombomys opimus, expends energy and possible risk of predation by footdrumming and vocalizing in the presence of a diversity of terrestrial predators: snakes, monitor lizards, polecats, foxes, and humans. Behavioral observations, human approaches, and experiments with tethered predators revealed that both male and female gerbils called and footdrummed in the presence of offspring, close relatives, and potential mates. Because adults called more often when pups were present, and solitary gerbils seldom gave an alarm, the alarm behavior probably warns conspecifics, especially vulnerable offspring, of potential danger. We also found that gerbils altered alarm behavior with the type of predator. They drummed more in the burrow when a dog that could not enter the burrow was present, and they drummed more out of the burrow in response to a snake that could enter the burrow. Gerbils vocalized and stood in an alert posture in response to all stimuli. The different footdrumming responses of gerbils to terrestrial predators seems related to the hunting style and type of risk posed by the predator, especially its ability to enter the burrow system.

Sex ratios were bimodally distributed in a population of the monogynous and monandrous ant Leptothorax nylanderi during each of 3 study years. The population-wide investment ratios suggested worker control of sex allocation. Nest-level variation in the proportional investment in virgin queens was not affected by the presence or absence of a queen and only slightly by collecting year, but was correlated with nest size, total sexual investment and, unexpectedly, with differences in nestmate relatedness: small, low-investment nests and nests with several worker lineages produced male-biased sex ratios. Colonies containing several worker lineages arise from usurpation of mature colonies by unrelated founding queens and the fusion of unrelated colonies under strong nest site limitation. In contrast to facultatively polygynous and polyandrous species of social insects, where workers can maximize their inclusive fitness by adjusting sex ratios according to the degree of relatedness asymmetry, workers in mixed colonies of L. nylanderi do not benefit from manipulating sex allocation, as here relatedness asymmetries appear to be the same as in homogeneous colonies.
