Substantive or Symbolic Environmental Strategies? Effects of External and Internal Normative Stakeholder Pressures 下载免费PDF全文
Different forms of stakeholder pressures drive different environmental strategies in organizations. This article differentiates between internal and external normative stakeholder pressures to test their potentially unique effects on environmental strategies. The findings suggest that internal, normative stakeholder pressures primarily drive substantive commitments to environmental practices, reflecting an internalized, voluntary commitment to the natural environment and dedication to environmental leadership by the firm. External, normative pressures instead primarily drive symbolic commitments to environmental practices, aimed at managing the image of the organization to establish and reinforce an appearance of commitment to the natural environment. This novel perspective accounts for the institutionally plural contexts of organizations and their environments, in which internal pressures directly drive substantive environmental commitments and external pressures drive symbolic responses.

There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies. In this paper, we share learning from efforts to mainstream such an approach through a large, multi-partner CGIAR research program working in aquatic agricultural systems. We reflect on four years of implementing research in development (RinD), the program’s approach to the new professionalism. We highlight successes and challenges and describe the key characteristics that define the approach. We conclude it is possible to build a program on a broader approach that embraces multidisciplinarity and engages with stakeholders in social-ecological systems. Our experience also suggests caution is required to ensure there is the time, space and appropriate evaluation methodologies in place to appreciate outcomes different to those to which conventional agricultural research aspires. 相似文献

Due to the advantages of being able to function under harsh environmental conditions and serving as a distributed condition information source in a networked monitoring system, the fibre Bragg grating (FBG) sensor network has attracted considerable attention for equipment online condition monitoring. To provide an overall conditional view of the mechanical equipment operation, a networked service-oriented condition monitoring framework based on FBG sensing is proposed, together with an intelligent matching method for supporting monitoring service management. In the novel framework, three classes of progressive service matching approaches, including service-chain knowledge database service matching, multi-objective constrained service matching and workflow-driven human-interactive service matching, are developed and integrated with an enhanced particle swarm optimisation (PSO) algorithm as well as a workflow-driven mechanism. Moreover, the manufacturing domain ontology, FBG sensor network structure and monitoring object are considered to facilitate the automatic matching of condition monitoring services to overcome the limitations of traditional service processing methods. The experimental results demonstrate that FBG monitoring services can be selected intelligently, and the developed condition monitoring system can be re-built rapidly as new equipment joins the framework. The effectiveness of the service matching method is also verified by implementing a prototype system together with its performance analysis. 相似文献

How Environmental Management Competitive Pressure Affects a Focal Firm's Environmental Innovation Activities: A Green Supply Chain Perspective 下载免费PDF全文
Recently, environmental management offers firms a source of competitive advantage in the marketplace. The development of environmental innovations is critical to the success of today's firms. Drawing on the Schumpeterian perspective of competition, this research examines how the perception of rival firms' green success influences a firm to pursue and produce environmental innovation through its green supply chain integration activities. Using survey data from 230 firms, a conceptual model is developed and tested using structural equation modeling. We find that the firms in our sample do perceive pressure from their competitors' success in environmental management activities, and thus take supply chain action to pursue integration activities. By differentiating incremental and radical environmental innovation, this study also reveals the role of three dimensions of green supply chain integration (internal, supplier, and customer integration of green product development) on incremental and radical environmental innovation separately. Specifically, findings suggest that green supply chain integration has a positive impact on developing incremental environmental innovation, while only customer integration has a significant positive impact on developing radical environmental innovation. 相似文献

We demonstrate that banks play an important monitoring role in CEO succession that is not observed for other types of lenders, particularly public bondholders. There is a stronger relation between cash flow performance and forced CEO turnover for firms issuing bank debt during the year of CEO turnover than for firms not issuing bank debt, and bank debt issuance increases the likelihood of external CEO succession. The stock price reaction to CEO succession is higher when bank monitoring is prevalent. Our results are consistent with theories of relationship banking that propose a valuable monitoring role for well informed, incentivized bank lenders. 相似文献

The objective of this study was to explore the relationship between promoter ownership and capital structure of firms’ using a sample of Indian publicly listed firms for the period from 2006 to 2013. We find that the relationship between promoter ownership and leverage is inversely U-shaped in group-affiliated firms, whereas in stand-alone firms there is a U-shaped relationship. We argue that a substantial presence of family owners and the selection of managers from within the family play some role for such relationship in group-affiliated firms. On the other hand, the argument for observed relationship in stand-alone firms follows from alignment hypothesis, entrenchment hypothesis, managerial risk aversion hypothesis, and active monitoring hypothesis. 相似文献

Personal managerial indiscretions are separate from a firm's business activities but provide information about the manager's integrity. Consequently, they could affect counterparties’ trust in the firm and the firm's value and operations. We find that companies of accused executives experience significant wealth deterioration, reduced operating margins, and lost business partners. Indiscretions are also associated with an increased probability of unrelated shareholder-initiated lawsuits, Department of Justice and Securities and Exchange Commission investigations, and managed earnings. Further, chief executive officers and boards face labor market consequences, including forced turnover, pay cuts, and lower shareholder votes at re-election. Indiscretions occur more often at poorly governed firms where disciplinary turnover is less likely. 相似文献
