Using an ARDL model for a panel of 15 OECD countries, this work analyses the impact that FDI, both jointly and by sector, has on CO2 emissions. The findings reveal that these countries are yielding to the pressure on the trade sector. Unexpectedly, gross fixed capital formation shrink pollution, excluding in the mining sector. With findings supporting the Pollution Haven Hypothesis, policymakers must pay attention to FDI inflows, ensuring that FDI place high importance on the transfer of green technologies to improve the efficiency. These goals could be achieved through an increase in the stringency of environmental laws within the host countries, especially the ones related to FDI.  相似文献

This paper investigates the relationship between FDI, democracy and corruption among 30 countries in Sub-Saharan Africa (SSA) over the period of 1985–2014 to determine whether the ‘helping hand’ or ‘grabbing hand’ hypothesis is most applicable. The results of GMM analysis show that corruption is used by FDI investors to overcome the region’s weak democratic regulatory and institutional status and thus the ‘helping hand’ is more prevalent. However, the results further show that as democratic capital accumulates, this association may outlive its usefulness and thus corruption as a ‘helping hand’ in time becomes a ‘grabbing hand’ instead. These results imply that SSA countries should focus on integrating into the international economy so as to take advantage of existing financial enforcement legislation while reconstructing and strengthening domestic constitutional anti-corruption legislation and institutions.  相似文献

The ‘age of metrics’ or ‘the metric tide’ in the form of bibliometrics has largely by‐passed Social Policy. This study aims to broaden the focus from the most cited articles in Social Policy journals to discover the most cited works in Social Policy or ‘Social Policy's Greatest Hits’. It finds some 24 works with over 2000 Google Scholar citations, but only nine of these are by social policy writers. In terms of total citations, Gosta Esping‐Andersen's The Three Worlds of Welfare Capitalism is the clear leader by a significant margin, with the most cited Social Policy (or Social Administration) writers being Peter Townsend, Richard Titmuss, Ruth Lister and Jane Lewis. In addition to total citations, it presents citations per year, and ‘Social Policy citations’ (i.e. the use made of the work within the discipline of Social Policy). This list is headed by Gosta Esping‐Andersen and Paul Pierson, with the leading social policy writer being Jane Lewis. This article presents a set of the ‘most plausible contenders’ for the works with greatest influence within Social Policy or ‘Social Policy's Greatest Hits’. It is concluded that, even with its flaws, bibliometrics is an important approach to exploring the vast field of Social Policy.  相似文献

Critical infrastructure networks enable social behavior, economic productivity, and the way of life of communities. Disruptions to these cyber–physical–social networks highlight their importance. Recent disruptions caused by natural phenomena, including Hurricanes Harvey and Irma in 2017, have particularly demonstrated the importance of functioning electric power networks. Assessing the economic impact (EI) of electricity outages after a service disruption is a challenging task, particularly when interruption costs vary by the type of electric power use (e.g., residential, commercial, industrial). In contrast with most of the literature, this work proposes an approach to spatially evaluate EIs of disruptions to particular components of the electric power network, thus enabling resilience‐based preparedness planning from economic and community perspectives. Our contribution is a mix‐method approach that combines EI evaluation, component importance analysis, and GIS visualization for decision making. We integrate geographic information systems and an economic evaluation of sporadic electric power outages to provide a tool to assist with prioritizing restoration of power in commercial areas that have the largest impact. By making use of public data describing commercial market value, gross domestic product, and electric area distribution, this article proposes a method to evaluate the EI experienced by commercial districts. A geospatial visualization is presented to observe and compare the areas that are more vulnerable in terms of EI based on the areas covered by each distribution substation. Additionally, a heat map is developed to observe the behavior of disrupted substations to determine the important component exhibiting the highest EI. The proposed resilience analytics approach is applied to analyze outages of substations in the boroughs of New York City.  相似文献

体验式学习的内涵随着时代的发展而逐渐丰富和深化,但无论其如何演变,直接经验和反思始终是体验式学习这一概念的内核。体验式学习理念渗透于美国教育文化之中。具体表现在:小学阶段的教育以学生的真实感知为基础,注重为学生提供真实体验的机会和激发学生的学习兴趣;中学尤其是高中阶段的教育以学生的真实体验为基础,注重为学生提供在新情境中检验所学知识的机会,注重学生知识、技能的内化吸收。美国中小学体验式学习的实施经验可为我国基础教育课程改革提供如下启示:(1)进一步树立和推广体验式学习理念;(2)创设学生进行真实体验的教学环境;(3)注重实施基于学生体验式学习的表现性评价。  相似文献

This paper explores how the British exit from the European Union (EU) potentially affects the United Kingdom (UK) economy and the production patterns of multinational enterprises that choose the UK as either a destination market or a gateway to the EU market. Utilizing an extended version of the knowledge-capital model, which includes six types of firms and four countries grouped into market and non-market, simulation analysis reveals that efforts to enhance attractiveness of the UK as a destination market to increase horizontal-type inward foreign direct investment would be a solution to cover losses from reduction in the number of export-platforms.  相似文献
