This research aims to evaluate the perceptions of and preferences for irrigation multifunctionality based on an analysis of stakeholder’ attitudes in a large irrigation system in Northern Italy, the Muzza canal. As the first artificial canal built in Northern Italy, this canal articulates a network of open earth canals that distribute water for irrigation, especially maize. The Stakeholder analysis approach and Governance model approach are applied. The collected data highlights: (1) each key stakeholder points of view regarding multifunctionality and ecosystem services, (2) the nature of conflicting attitudes regarding who and how the Muzza system is managed, and (3) the ability or inability to promote agreements among conflicting water demands. The results show how public administration is concerned about how to manage ecosystem services provided by irrigation practices, while private services are focused on how to guarantee the coexistence of consumptive and non-consumptive water uses, highlighting the persistent conflict between farming production and environmental protection. The rural community and civil society call for a debate about the future of irrigation multifunctionality in the Muzza system and the role of irrigation practices in landscape provision and management. In addition, the paper examines if multifunctionality is a characteristic or an objective of irrigation systems. These results can be used by researchers and relevant authorities to customize their interventions based on previous, well-structured knowledge of various stakeholders’ priorities. 相似文献

There are repeated calls to go ‘Beyond GDP’, for measures of wellbeing and progress in addition to those that the System of National Accounts (SNA) is designed to provide. We identify key issues that can help build on the rigour of SNA whilst fitting the measurement of economic performance within a broader assessment of national wellbeing and progress. Such drivers are already leading to a proliferation of indicators and accounts, for example in the development of non‐monetary measures of natural resources, but there are significant measurement challenges, not least the question of whether a single, overall measure or index of wellbeing is valid. But the challenge of measurement, per se, is one thing: in our view, a more critical issue is whether the measures will actually be used. We propose a dynamic and multi‐staged approach for developing SNA, embracing the production and use of measures. This would start by identifying user requirements for wider measures, to provide the basis for national and cross‐national developments in well‐being accounting. We envisage greater branding and marketing of national well‐being concepts to promote measures and support their use. We call for outreach by producers, so that there is dialogue about the development and use of measures. 相似文献

Organizations in disaster management system should learn from previous experience and strategically use their lesson for the refinement of a system’s competencies for risk management. However, the MV Sewol incident revealed the absence of the organizational learning in the Korean disaster management system. With mixed methods of content analysis, in-depth interview, and social network analysis, this study identified key failure factors in response to the incident and categorized them by managerial, structural, and institutional domains. While the Korean government took bold steps to rebuild its risk management system, those efforts were biased to structural reforms and lacked fundamental changes in human and informational resources management. Based on the findings, this study suggests the balanced efforts for system refinement for effective risk management. 相似文献

Two fundamental options exist for management accounting system (MAS) design: Either financial records can be used as a database for management accounting (integrated accounting system design), or the MAS can be based upon a separate system, i.e., a third set of books beside financial and tax accounting records. Since the 1990s, many German-speaking firms have changed from the second to the first option, which has instigated a highly controversial debate.Our paper contributes to this debate by empirically analyzing (1) whether the integration of financial and management accounting has a positive impact on controllership effectiveness, and (2) what causal inferences relate both variables. We use structural equation modelling for a sample of 149 dyads surveyed from German top 1500 firms. We identify no significant effect of the technical aspects of MAS integration, but a fully mediating influence of a consistent financial language on controllership effectiveness. Our results thus imply that consistency with financial reporting is an important property of MAS design from management's point of view. 相似文献

Recent legislation intended to increase the use of renewable energy sources and lower the amount of carbon dioxide emissions from energy has changed the structure of energy markets. The effect of these policies on carbon-intensive fuel sources is rather obvious. For natural gas, though, the effect is not immediately clear. This letter uses a structural model of natural gas demand to uncover whether these policies have led to increased demand because natural gas is a relatively clean source of energy that couples well with renewables or if these policies have crowded out natural gas on net. 相似文献

由于目前关于建筑行业资质管理对建筑产业的有效性存在正反两方面不同看法,双方虽有定性理论分析和国外资质管理根据,但是无法说明资质管理对我国建筑产业整体收益具体影响,因而从个体企业行为角度出发,根据多智能体理论,使用Netlogo建模平台,建立中国建筑业的交易行为互动流程,模拟运行建筑产业执行或不执行资质管理的情况,观察并分析论证了资质管理有利于提高中国建筑产业收益能力。此外,在模拟过程中发现资质管理对产业结构也存在影响。 相似文献

文章在经济转型和大城市人口调控背景下,研究了上海劳动力资源供需平衡趋势与外来劳动力需求情况。研究显示,在上海经济保持一定的增长速度下,2015-2020年外来劳动力需求量在700-856万人之间,这使大城市在对待外来劳动力上处于尴尬境地,一方面面临着经济发展对外来劳动力的依赖性,另一方面面临着大城市人口调控的压力。目前上海劳动力市场中外来劳动力与本地劳动力在就业岗位、工资待遇、社会福利等方面仍存在一定的差异。外来劳动力与本地劳动力在岗位上更多的是一种优势互补关系,对外来劳动力歧视有悖于社会公平理论,同时政府的强行调控政策也不利于劳动力市场的发展。政府的职责应该是尽可能地创造出健康、有序、公平的市场秩序,让市场在调节劳动力供需和结构性短缺上发挥决定性作用。 相似文献

采用多元层级回归方法,对影响供应商创新能力的驱动因素以及供应商在供应链网络中的等级位置对各驱动因素与供应商创新能力间关系的调节作用进行了理论探讨和实证分析。结果显示:在跨国外包情景下,发包方支持、共享活动和联结强度对供应商的创新能力具有显著的积极影响;供应商在供应链网络中的等级位置对联结强度与供应商创新能力间关系具有显著的正向调节作用,对共享活动与供应商创新能力间关系的正向调节作用不稳定。 相似文献
