The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy
cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops
(switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, anestimated 17 million hectares of bioenergycrops,
annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural
usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program
lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually
by US $6.0billion above baseline.At farmgate prices of US $1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually
yielding 55 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor
the land. The estimate assumes managementpractices intended to achieve highenvironmental benefits on Conservation ReserveProgram
lands. Traditional crops prices areestimated to increase 4 to 9 percent abovebaseline prices and farm income increasesannually

Edward Peter Stringham’s book Private Governance: Creating Order in Economic and Social Life (2015) is a compelling defense of the proposition that private governance is more widely used and more effective than most people think. Stringham looks to history to see how people solved problems of fraud and cheating without government intervention and provides example after compelling example to contradict the strong claim that a government or any third-party enforcer is necessary for voluntary exchange. While Stringham doesn’t take on the tough problem that private governance is not sufficient for its task, his book is intended to be the beginning, not the end, of thinking about private governance. 相似文献

The aim of this study is to provide a foundation for researchers and managers to discuss and resolve difficulties associated with research and development (R&D) target‐setting. While multiple studies mention the difficulty of R&D target‐setting, few have compiled reasons for these difficulties or addressed this issue in detail. This paper provides one of the first studies outlining reasons for R&D target‐setting difficulties through a literature review. It also provides an initial set of analyses and results after applying an emerging quantitative method, Technology Forecasting Using Data Envelopment Analysis (TFDEA), to illustrate these difficulties step‐by‐step to commercial airplanes. Results include determining the state of art in commercial airplane technology and technological rate‐of‐change variants in setting R&D targets. 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

Muslim immigrants to Europe display distinctive attitudes toward women in a wide range of survey data. This study investigates whether this translates into distinctive behavior. Relying on a dictator game in France and an identification strategy that isolates the effect of religion from typical confounds such as race, we compare the donations of matched Christian and Muslim immigrants and rooted French to in‐group and out‐group men vs. women. Our results indicate that Muslim immigrant participants deviate from Christian immigrant and rooted French participants in their behavior toward women: while the latter favor women over men, Muslim immigrants favor men over women. 相似文献

Technological innovations are important sources of competitive advantage when there is a balanced rate of adoption that helps organisations maintain or improve performance levels. This paper synthesises and builds on efforts to conceptualise the adoption and implementation of technologically induced customer services in developing countries. Its point of departure is recent advances in computer-mediated marketing environments (CMMEs). It assesses relationships between customer services and evolving technologies in the provision of services in the banking sector. Using phenomenological hermeneutics and a case study approach, we iteratively engaged with data that emerged to identify core values and community-based values. These facets were further developed into seven main issues (core values: quality, education and reach, and community-based values: efficiency, usability, control and security). The paper offers practical steps by which companies and institutions may counter these issues and the theoretical implications for wider considerations are discussed. 相似文献

High-quality, accessible, and efficient primary care is needed as the U.S. health care system undergoes significant change. Advancing the role of registered nurses in the primary care setting is important to the solution. A large academic health center implemented five initiatives to improve the care of chronically ill patients through the expanded role of RNs in the context of the health care team. Role evolution of nurses in the pilots required some continuing education and some additional nursing support to release the pilot nurses from their usual duties. These strategies allowed the nurses to apply interventions that enhanced the coordination of care and promoted patient self-management skills. Some short-term improvements in health status were realized and barriers to self-care were identified and resolved. 相似文献

An N-player game can be decomposed by adding a coordinator who interacts bilaterally with each player. The coordinator proposes
profiles of strategies to the players, and his payoff is maximized when players’ optimal replies agree with his proposal.
When the feasible set of proposals is finite, a solution of an associated linear complementarity problem yields an equilibrium
of the approximate game and thus an approximate equilibrium of the original game. Computational efficiency is improved by
using vertices of a triangulation of the players’ strategy space for the coordinator’s pure strategies. Computational experience
is reported. 相似文献

Injection drug users (IDUs) transmit the human immunodeficiency virus (HIV) via both needle sharing and sex. Available interventions for this population have varying costs and effectiveness and focus on different risk behaviors. In this analysis, we look at two interventions. One is inexpensive, broad-based and provides modest risk reductions (street outreach (SO)); the other is narrowly focused, expensive and relatively effective (methadone maintenance). This analysis explores the effects of population risk behavior, intervention effectiveness, intervention costs, and decision constraints when allocating funds between these two interventions to maximize effectiveness. We develop a model of the spread of HIV, dividing IDUs into susceptibles (uninfected) and infectives, and separately portraying sex and injection risk. We simulate the epidemic in New York City for time periods from the mid-1980s to the early 1990s, and incorporate the behavioral effects of two interventions performed singly or in combination to find the allocation that maximizes the number of infections averted in the IDUs and their noninjecting sex partners, assuming interventions have increasing marginal costs. We find that the optimal allocation nearly always involves spending the maximum allowable amount on SO. This result is largely insensitive to variations in risk parameters, intervention efficacy, or cost. The model's structure, however, makes clear that many factors contribute to this insensitivity, namely the scope of the interventions, the dual drug/sex nature of HIV risk in the population, the asymmetry of sexual risk for men and women, and the potential benefits to nonIDUs. 相似文献
