This paper assesses the current status and future prospects for bioregional planning in the Southern Appalachian Man and the Biosphere (SAMAB) region in the United States. The SAMAB region is one of the most biodiverse temperate regions in the world. The region's environment is threatened by development, air and water pollution, and invasive species. Numerous institutions in the region have some responsibility for protecting the region's environment, including the National Park Service, the US Forest Service, the US Environmental Protection Agency, the US Fish and Wildlife Service, several states, hundreds of municipalities, and numerous active non-profit organizations. Twenty-seven people associated with bioregional planning were interviewed to gauge their opinions on the state of bioregional planning in the SAMAB region. Overall, the respondents do not believe that the totality of all those efforts comprises bioregional planning because the efforts are limited in scale and scope and somewhat uncoordinated. With respect to the future of the region, the respondents found it difficult to imagine the state of the region 50 and especially 200 years into the future. Additionally, almost all of their definitions of bioregional planning included a spatial dimension but none included a time dimension. Thus, one of our conclusions is that the future of bioregional planning in the region will be hampered by difficulties people responsible for environmental protection have in dealing with ‘the future’. Much effort needs to be expended to inculcate people in the region with the desire to anticipate problems long before they occur. Reactive responses, which characterize the majority of current efforts, are likely to be ‘too little, too late’. 相似文献

The Effects of Bilateral Tax Treaties on U.S. FDI Activity 总被引:1,自引:0,他引:1
The effects of bilateral tax treaties on FDI activity have been unexplored, despite significant ongoing activities by countries to negotiate and ratify these treaties. This paper estimates the impact of bilateral tax treaties using both U.S. inbound and outbound FDI over the period 1980–1999. Robust to a wide variety of alternative specifications, we find little evidence that bilateral tax treaties increase FDI activity, contrary to OECD-stated goals for such treaties. 相似文献

This paper documents evidence on the efficacy of maturity-gap disclosures of commercial banks in indicating their net interest income that is exposed to interest-rate risk. For the large sample of banks that filed call reports from 1990 to 1997, a period that includes a wide range of interest rate movements, we find that (i) one-year maturity gap measures are significantly related to the one-year- and three-years-ahead change in net interest income, (ii) fixed-rate and variable-rate instruments differ in explanatory ability, and (iii) the one-to-five-year aggregate gap measures also have some power in explaining three-year-ahead changes in net interest income. These findings hold after controlling for the ex post growth in assets as well as the amount of rate-sensitive assets and liabilities (a competing set of explanatory variables). Because the Securities and Exchange Commission (SEC)'s [Securities and Exchange Commission (SEC), (1997). Disclosure of accounting policies for derivative financial instruments and derivative commodity instruments and disclosure of qualitative and quantitative information about market risk inherent in derivative financial instruments, other financial instruments, and derivative commodity instruments. Release Nos. 33-7386; 3438223; IC-22487; FR-48; International Series No. 1047; File No. S7-35-95 (January 31, 1997), Washington, DC] tabular disclosures are finer than maturity-gap data, our findings mitigate concerns about the usefulness of the SEC's market-risk-disclosure requirements. Furthermore, they suggest contrary to the claims of certain banks that the omission of prepayment and early withdrawal risk from gap measures does not totally compromise the ability of gap data to indicate interest-risk exposures. 相似文献

In a first for South Africa, this article draws on literature on infrastructure productivity to model dynamic economy-wide employment impacts of infrastructure investment funded with different fiscal tools. Using a dynamic computable general equilibrium model, the South African investment plan is modelled, given the infrastructure externality. Alternative fiscal scenarios to finance the policy are modelled in the article. In the long run, unemployment decreases for all types of workers under one of the scenarios. In the short run, only elementary occupation workers benefit from a decrease in unemployment; for the rest, unemployment rises. 相似文献

In this article, the authors are the first to describe the core economics curriculum requirements for economics majors at all American colleges and universities, as opposed to a sample of institutions. Not surprisingly, principles of economics is nearly universally required and implemented as a two-semester course in 85 percent of economics major programs. Most schools do not prescribe the order in which the principles sequence is taken. The intermediate courses are commonly required, although variation exists across institution types. While the quantitative requirement for the major has increased since 1980, significant differences exist among institutions and by academic rankings. As compared to 1950, there has been an increase in the number of required economics credit hours for the major. 相似文献

Tipping is a well-established social norm in North American restaurants. Researchers have given considerable attention to the interaction between consumers and servers, but less so to the relationships within a restaurant and even less so to restaurant managers’ perspectives. Our study, the first of its kind, used interviews and a survey to explore the perspectives of both restaurant managers and servers in identifying operational issues arising from tipping. Inequity and unfairness, loss of control of service quality, and difficulties in succession planning and promotion were identified. There is clearly a need to investigate strategies to mitigate some of these impacts. 相似文献

Cities are key drivers of global climate change, with the majority of greenhouse gas (GHG) emissions being tied to urban life. Local actions to mitigate and adapt to climate change are essential for stabilization of the global climate and can also help to address other urban ecological problems such as pollution, decreasing biodiversity, etc. Companies are important urban actors in the development of low‐carbon cities because they provide a multitude of goods and services to city populations and directly influence urban carbon dioxide (CO2) emissions. This is a new area of research. While studies on corporate sustainability are numerous, there is little, if any, existing research that examines the role of companies in climate change adaptation and mitigation within specific urban areas. Urban ecologists also have not examined how corporate activity affects urban systems. Taking a multi‐disciplinary systems approach, we present a conceptual model of the role of companies in managing urban interactions with the climate system. We also present empirical findings illustrating how one company ‘partners’ with the city of Rotterdam to test electric vehicles as a pilot project for urban climate adaptation and mitigation.
