A call has been made for conservation planners to include ecosystem services into their assessments of conservation priority areas. The need to develop an integrated approach to meeting different conservation objectives and a shift in focus towards human wellbeing are some of the motivations behind this call. There is currently no widely accepted approach to planning for ecosystem services. This study contributes towards the development of this approach through a review of conservation assessments and the extent to which they include ecosystem services. Of the 476 conservation assessments identified by a set of search terms on the Web of Science, 100 were randomly selected for this review. Of these only seven had included ecosystem services, while another 13 had referred to ecosystem services as a rationale for conservation without including them in the assessment. The majority of assessments were based on biodiversity pattern data while 19 used data on ecological processes. A total of 11 of these 19 assessments used processes, which could be linked to services. Ecosystem services have witnessed an increase in attention received in conservation assessments since the year 2000, however trends were not apparent beyond this date. In order to assess which types of ecosystem services and how they have been accounted for in conservation assessments, we extended our review to include an additional nine conservation assessments which included ecosystem services. The majority included cultural ecosystem services, followed by regulatory, provisioning and supporting services respectively. We conclude with an analysis of the constraints and opportunities for the integration of ecosystem services into conservation assessments and highlight the urgent need for an appropriate framework for planning for ecosystem services. 相似文献

In this study the author investigates firm-level cross-sectional unit cost advantages for electricity generation for 31 regulated private steam-electric utilities in East-North-Central U.S. region during 1987. The production technology is modeled using the implied dual minimum total variable cost translog methodology. Estimates of Zellner’s Seemingly Unrelated Regressions indicate a smooth non-homothetic technology, a typical regional firm-level scale economies of about 0.263, and an implied mean cost-output elasticity of about 0.737. Significant scale economies exist for several of the smaller utilities. The findings support policies which steer energy-intensive industrial location decisions in a direction which captures unutilized unit cost economies in electricity generation. 相似文献

This paper considers why firms differ in the degree to which they rely on their internal R&D organization for generating new technologies (induced innovations) rather than on existing external technology markets (purchased innovations). An empirical model is suggested to explan inter-firm differences in the percentage of new technology induced through R&D efforts. The analysis suggests that such differences are systematically related to the firm's size, its competative environment, and its degree of diversification. 相似文献

PDMA Success Measurement Project: Recommended Measures for Product Development Success and Failure 总被引:16,自引:0,他引:16
Success is not just elusive; it is also multifaceted and difficult to measure. A firm can assess the success or failure of a development project in any (or all) of many terms, including customer satisfaction, financial return, and technical advantage. To complicate matters, success may be measured not only at the level of the individual project, but also at the program level. With so many variables to consider and so many stakeholders involved, managers face a difficult challenge just deciding which measures are useful for measuring product development success. Recognizing that no single measure suffices for gauging the success of every product development project, Abbie Griffin and Albert L. Page hypothesize that the most appropriate set of measures for assessing project-level success depends on the project strategy. For example, the objectives (and thus, the success criteria) for a new product that creates an entirely new market will differ from those of a project that extends an existing product line. Similarly, they hypothesize that the appropriate measures of a product development program's overall success depend on the firm's innovation strategy. For example, a firm that values being first to market will measure success in different terms from those used by a firm that focuses on maintaining a secure market niche. To test these hypotheses, product development professionals were presented with six project strategy scenarios and four business strategy scenarios. For each project strategy scenario, participants were asked to select the four most useful measures of project success. For each business strategy scenario, participants were asked to choose the set of four measures that would provide the most useful overall assessment of product development success. The responses strongly support the idea that the most appropriate measures of project-level and program-level success depend on the firm's project strategy and business strategy, respectively. For example, customer satisfaction and customer acceptance were among the most useful customer-based measures of success for several project strategies, but market share was cited as the most useful customer-based measure for projects involving new-to-the-company products or line extensions. At the program level, firms with a business strategy that places little emphasis on innovation need to focus on measuring the efficiency of their product development program, while innovative firms need to assess the program's contribution to company growth. 相似文献

Over the past two decades, there has been growing interest in corporate social responsibility (CSR) among accounting scholars. As a testament to this growing interest, two review papers on CSR were published last year in accounting journals. Implicitly guiding hypothesis development in CSR studies is the notion of a conflict between shareholders and stakeholders. We define CSR in terms of a win-win situation for shareholders and stakeholders: a CSR framework for strategic business purposes. We provide evidence supporting this outlook for CSR using cases pertaining to specific companies and findings from archival empirical studies. According to our CSR framework, resources allocated for CSR activity also help propel business strategy; as such, it is difficult to isolate CSR inputs and/or outputs due to problems of non-separability and multidimensionality. While measurement is a challenge, our framework nonetheless opens up various promising avenues for future research. 相似文献

We use expert clinical and public health opinion to estimate likely changes in the prevention and treatment of important disease conditions and how they will affect future life expectancy. Focus groups were held including clinical and public health faculty with expertise in the six leading causes of death in the United States. Mortality rates and life tables for 2040 were derived by sex and age. Life expectancy at age 20 and 65 was compared to figures published by the Social Security Administration and to estimates from the Lee-Carter method. There was agreement among all three approaches that life expectancy at age 20 will increase by approximately one year per decade for females and males between now and 2040. According to the clinical experts, 70% of the improvement in life expectancy will occur in cardiovascular disease and cancer, while in the last 30 years most of the improvement has occurred in cardiovascular disease. Expert opinion suggests that most of the increase in life expectancy will be attributable to the already achieved reduction in smoking rates, especially for women. 相似文献

Despite the widespread recognition of the paybacks of “going green” and “going clean,” limited research has focused on the impact of lean‐green strategy on firm growth. In this study, we contribute to strategy and environmental sustainability literatures by investigating the possibility that the influence on lean‐green strategy and firm growth is driven by different levels of industry competition, managerial power, and family ties. Using panel data from 732 firms in four major industrialized economies (the United States, Germany, France, and the United Kingdom), we found that lean‐green strategy positively relates to firm growth and this relationship is amplified at higher levels of competition, managerial power, and family ties. Theoretical and practical implications of the study are also discussed. 相似文献

This article develops an ethnographic account of the development and history of the British Airways Heritage Centre (BAHC). Responding to several observations throughout the literature, we report on our experiences of engagement with British Airways’ archives over a 25-year period. In doing so our focus is on the much-neglected history of archives as powerful influences on how corporate histories are written. The ethnographic account is rooted in ANTi-History, an approach to historiography, that focuses on the production of history as knowledge of the past by following a number of human (e.g. archive volunteers) and non-human (e.g. airline artefacts) actors to reassemble the elements that constitute an archive at a point in time. To that end, we trace the inter-relationships between histories of British Airways and the development of the BAHC. We conclude that a focus on the various human and non-human relationships that constitute an archive can help the researcher to identify the hidden influences on the production of history that can otherwise serve to enrol him or her. 相似文献
