    Hydrogen (H2) offers advantages as an energy carrier: minimal discharge of pollutants, production from multiple sources, increased thermodynamic efficiencies compared to fossil fuels, and reduced dependence on foreign oil. However, potential impacts from the H2 generation processes, transport and distribution of H2, and releases of H2 into the atmosphere have been proposed. The goal of this project was to analyze the effects of emissions of hydrogen, the six criteria pollutants and greenhouse gases on climate, human health, materials and structures. This project was part of a larger effort by DOE to assess the life-cycle costs and benefits and environmental impacts to inform decisions regarding future hydrogen research. Technical Approach: A modeling approach was developed and used to evaluate the potential environmental effects associated with the conversion of the on-road vehicle fleet from fossil-fuel vehicles to hydrogen fuel cell vehicles. GATOR-GCMOM was the primary tool used to predict atmospheric concentrations of gases and aerosols for selected scenarios. This model accounts for all feedbacks among major atmospheric processes based on first principles. The future scenarios and the emission rates selected for this analysis of hydrogen environmental effects are based on the scenarios developed by IPCC. The scenarios selected for the model simulations are a 2000 and 2050 A1B base cases, and a 2050 A1B case with hydrogen fuel cell vehicles (HFCVs). The hydrogen fuel cell scenario assumed conversion of 90% of fossil-fuel on-road vehicles (FFOV) in developed countries and 45% of FFOVs vehicles in other countries to HFCVs, with the H2 produced by steam-reforming of natural gas (SHFCVs). Simulations were conducted to examine the effect of converting the world's FFOVs to HFCVs, where the H2 is produced by wind-powered electrolysis (WHFCVs). In all scenarios a 3% leakage of H2 consumed was assumed. Two new models were developed that provide the ability to evaluate a

    In the US, the transportation sector consumes over one quarter of the entire energy used, almost in its entirety as petroleum products, and in quantities greater than the total US domestic oil production. The transportation sector is responsible for a significant fraction of all emissions that either prevent US cities from achieving compliance with EPA air quality standards or have serious global change implications. Finally, the GDP (Gross Domestic Product) and employment due to the sector are low and incommensurate with the high fraction of energy that the transportation sector consumes. We examine below this situation in some detail and make recommendations for improvements.

    The report evaluates the economic and social impacts of supporting the Southeast Pennsylvania Transportation Authority (SEPTA) public transportation system. The study is comprehensive, considering travel times and costs for individual travelers, and how those changes would affect the cost of doing business, individual spending patterns, and the regional and State economies. Four alternatives were considered: rehabilitation of the system and continuation of services, a fifty-percent scaleback of services, gradual shutdown of the system over ten years, and immediate shutdown. The analysis showed that rehabilitation of the system would return three dollars to the region for every dollar spent on it, and that cutting back service would have economic costs far greater than any savings accrued. The methodology is general, and can be applied in other areas.

  6. The effectiveness of policy on consumer choices for private road passenger transport emissions reductions in six major economies

    The effectiveness of fiscal policy to influence vehicle purchases for emissions reductions in private passenger road transport depends on its ability to incentivise consumers to make choices oriented towards lower emissions vehicles. However, car purchase choices are known to be strongly socially determined, and this sector is highly diverse due to significant socio-economic differences between consumer groups. Here, we present a comprehensive dataset and analysis of the structure of the 2012 private passenger vehicle fleet-years in six major economies across the World (UK, USA, China, India, Japan and Brazil) in terms of price, engine size and emissions distributions. We argue that choices and aggregate elasticities of substitution can be predicted using this data, enabling us to evaluate the effectiveness of potential fiscal and technological change policies on fleet-year emissions reductions. We provide tools to do so based on the distributive structure of prices and emissions in segments of a diverse market, both for conventional as well as unconventional engine technologies. We find that markets differ significantly between nations, and that correlations between engine sizes, emissions and prices exist strongly in some markets and not strongly in others. We furthermore find that markets for unconventional engine technologies have patchy coverages of varying levels. These findings are interpreted in terms of policy strategy.

    This thesis describes the development and testing of a nonlinear macroeconomic model designed to assess the impacts and interactions of energy in the Jamaican economy. In its application, the model has much wider uses. It is particularly relevant for planning in developing economies where single or multifactor constraints to growth exist, or where relatively little time-series or cross-sectional data is available. The model consists of three components: an input-output account of national economic activities, a set of eigen equations, and a Taylor Series Expansion Equation. The model then simulates the energy economy as an eigen problem and uses the eigen values through a Taylor expansion of the accounts, with various intensity changes in the energy supply components, to derive the implicit macro and socioeconomic interactions. The model was tested for the year 1977, and then used to forecast value added and final demand components for 1982 with very encouraging results.

  9. Hydrogen based emergency back-up system for telecommunication applications

    NASA Astrophysics Data System (ADS)

    Varkaraki, E.; Lymberopoulos, N.; Zachariou, A.

    This paper presents the design of a hydrogen based emergency back-up system for telecommunication applications, providing 5 kW power for 5 h. The system is composed of a water electrolysis unit, a hydrogen buffer tank, a metal hydride tank and a polymer electrolyte membrane fuel cell (PEMFC). In particular, the paper describes the design of the hydrogen generation and storage section and the various options that have been studied, based on technical and economical considerations of state-of-the-art hydrogen technologies. The water electrolyser produces 0.5 Nm 3 H 2/h at 10 bar pressure. The 1 m 3 conventional medium pressure tank has a capacity of approximately 6 Nm 3 H 2 and the metal hydride tank a capacity of 15 Nm 3 H 2. Particular attention is paid to the integration of the hydrogen storage and the fuel cell, with respect to optimizing heat exchange.

    The search for extraterrestrial life may be facilitated if ecosystems can be found on Earth that exist under conditions analogous to those present on other planets or moons. It has been proposed, on the basis of geochemical and thermodynamic considerations, that geologically derived hydrogen might support subsurface microbial communities on Mars and Europa in which methanogens form the base of the ecosystem1-5. Here we describe a unique subsurface microbial community in which hydrogen-consuming, methane-producing Archaea far outnumber the Bacteria. More than 90% of the 16s ribosomal DNA sequences recovered from hydrothermal waters circulating through deeply buried igneous rocks in Idaho are related to hydrogen-using methanogenic microorganisms. Geochemical characterization indicates that geothermal hydrogen, not organic carbon, is the primary energy source for this methanogen-dominated microbial community. These results demonstrate that hydrogen-based methanogenic communities do occur in Earth's subsurface, providing an analogue for possible subsurface microbial ecosystems on other planets.

    2015-12-01

    This paper is evaluating two power generation concepts based on hydrogen produced from bioethanol steam reforming at industrial scale without and with carbon capture. The power generation from bioethanol conversion is based on two important steps: hydrogen production from bioethanol catalytic steam reforming and electricity generation using a hydrogen-fuelled gas turbine. As carbon capture method to be assessed in hydrogen-based power generation from bioethanol steam reforming, the gas-liquid absorption using methyl-di-ethanol-amine (MDEA) was used. Bioethanol is a renewable energy carrier mainly produced from biomass fermentation. Steam reforming of bioethanol (SRE) provides a promising method for hydrogen and power production from renewable resources. SRE is performed at high temperatures (e.g. 800-900°C) to reduce the reforming by-products (e.g. ethane, ethene). The power generation from hydrogen was done with M701G2 gas turbine (334 MW net power output). Hydrogen was obtained through catalytic steam reforming of bioethanol without and with carbon capture. For the evaluated plant concepts the following key performance indicators were assessed: fuel consumption, gross and net power outputs, net electrical efficiency, ancillary consumptions, carbon capture rate, specific CO2 emission etc. As the results show, the power generation based on bioethanol conversion has high energy efficiency and low carbon footprint.

    A hydrogen-based economy seems superficially to be environmentally friendly, and many people have worked toward its realization. Today hydrogen is mainly produced by decarbonizing fossil fuels (e.g. natural gas), and in the future decarbonization of both fossil fuels and biomass will play a leading role in the production of hydrogen. The main purpose of this paper is to suggest the identification of potential environmental risks in terms of 'life cycle thinking' (which considers all aspects from production to utilization) with regard to the hydrogen-based economy to come. Hydrogen production by decarbonization results in CO{sub 2} emissions. The final destination of the recovered CO{sub 2} is uncertain. Furthermore, there is a possibility that hydrogen molecules will escape to the atmosphere, posing risks that could occasion global environmental changes such as depletion of stratospheric ozone, temperature change in the stratosphere and change of the hydrides cycle through global vaporization. Based on the results of simulation, requirements regarding the following items are proposed to minimize potential risks: hydrogen source, production and storage loss.

At the April 2002 joint meeting of the American Physical Society and American Astronomical Society, I announced that comets were composed of antimatter, there were 109 antimatter elements, and the Periodic Table of Elements had been updated to include the antimatter elements. When matter and antimatter come together, energy is produce according to Einstein's equation of mass times the speed of light squared or E = mc2. Antimatter energy creates incredible opportunities for humanity. People in spacecraft will travel to the moon in hours, planets in days, and stars in weeks. Antimatter power will replace fossil plants and produce hydrogen from off-peak electrical power. Hydrogen will supplant gas in cars, trucks, and other vehicles. The billions of ton of coal, billions of barrels of oil, and trillions of cubic feet of natural gas will be used to make trillions of dollars of products to bring countries into the 21st century. Within this millennium, the Worlds Gross National Product will increase from 30 trillion to 3,000 trillion plus 1,500 trillion from space commercialization bringing the Total Gross National Product to 4,500 trillion. Millions of businesses and billions of jobs will be created. However, the real benefits will come from taking billions of people out of poverty and empowering them to pursue their dreams of life, liberty and pursuit of happiness.

    2007-09-01

    The 20th Century was the age of the Petroleum Economy while the 21st Century is certainly the age of the Solar-Hydrogen Economy. The global Solar-Hydrogen Economy that is now emerging follows a different logic. Under this new economic paradigm, new machines and methods are once again being developed while companies are restructuring. The Petroleum Economy will be briefly explored in relation to oil consumption, Hubbert's curve, and oil reserves with emphasis on the "oil crash". Concerns and criticisms about the Hydrogen Economy will be addressed by debunking some of the "hydrogen myths". There are three major driving factors for the establishment of the Solar-Hydrogen Economy, i.e. the environment, the economy with the coming "oil crash", and national security. The New Energy decentralization pathway has developed many progressive features, e.g., reducing the dependence on oil, reducing the air pollution and CO II. The technical and economic aspects of the various Solar-Hydrogen energy options and combinations will be analyzed. A proposed 24-hour/day 200 MWe solar-hydrogen power plant for the U.S. with selected energy options will be discussed. There are fast emerging Solar Hydrogen energy infrastructures in the U.S., Europe, Japan and China. Some of the major infrastructure projects in the transportation and energy sectors will be discussed. The current and projected growth in the Solar-Hydrogen Economy through 2045 will be given.

    2016-01-01

    In this review article, nanocatalysts for solar hydrogen production are the focus of discussion as they can contribute to the development of sustainable hydrogen production in order to meet future energy demands. Achieving this task is subject of scientific aspirations in the field of photo- and photoelectrocatalysis for solar water splitting where systems of single catalysts or tandem configurations are being investigated. In search of a suitable catalyst, a number of crucial parameters are laid out which need to be considered for material design, in particular for nanostructured materials that provide exceptional physical and chemical properties in comparison to their bulk counterparts. Apart from synthetic approaches for nanocatalysts, key parameters and properties of nanostructured photocatalysts such as light absorption, charge carrier generation, charge transport, separation and recombination, and other events that affect nanoscale catalysts are discussed. To provide a deeper understanding of these key parameters and properties, their contribution towards existing catalyst systems is evaluated for photo- and photoelectrocatalytic solar hydrogen evolution. Finally, an insight into hydrogen production processes is given, stressing the current development of sustainable hydrogen sources and presenting a perspective towards a hydrogen-based economy.

    This report presents a microsimulation model of a transition economy. Transition is defined as the process of moving from a state-enterprise economy to a market economy. The emphasis is on growing a market economy starting from basic microprinciples. The model described in this report extends and modifies the capabilities of Aspen, a new agent-based model that is being developed at Sandia National Laboratories on a massively parallel Paragon computer. Aspen is significantly different from traditional models of the economy. Aspen`s emphasis on disequilibrium growth paths, its analysis based on evolution and emergent behavior rather than on a mechanistic view of society, and its use of learning algorithms to simulate the behavior of some agents rather than an assumption of perfect rationality make this model well-suited for analyzing economic variables of interest from transition economies. Preliminary results from several runs of the model are included.

    Recent discoveries of methane hydrates under the Arctic permafrost and on continental shelves have revealed an immense energy resource. This has two major implications for the Solar Power Satellite (SPS). First, the SPS will not be built unless it can produce electricity at a price competitive with that generated using methane from hydrates (perhaps with sequestration of carbon dioxide). Second, steam reformation of methane is much cheaper than water electrolysis as a source of hydrogen, so there is little role for the SPS (or any other electric power technology) in the proposed hydrogen economy. On the other hand, an economy based on methane-electric hybrid vehicles offers advantages quite comparable to the hydrogen economy, without its technical problems and immense capital requirements. The methane economy also offers a transitional path to increasing direct use of electricity in transportation, a development that could create a major market for the SPS.

    To make informed decisions about travel and vehicle purchase, consumers need unbiased and accurate information of the fuel economy they will actually obtain. In the past, the EPA fuel economy estimates based on its 1984 rules have been widely criticized for overestimating on-road fuel economy. In 2008, EPA adopted a new estimation rule. This study compares the usefulness of the EPA's 1984 and 2008 estimates based on their prediction bias and accuracy and attempts to improve the prediction of on-road fuel economies based on consumer and vehicle attributes. We examine the usefulness of the EPA fuel economy estimates using a large sample of self-reported on-road fuel economy data and develop an Individualized Model for more accurately predicting an individual driver's on-road fuel economy based on easily determined vehicle and driver attributes. Accuracy rather than bias appears to have limited the usefulness of the EPA 1984 estimates in predicting on-road MPG. The EPA 2008 estimates appear to be equally inaccurate and substantially more biased relative to the self-reported data. Furthermore, the 2008 estimates exhibit an underestimation bias that increases with increasing fuel economy, suggesting that the new numbers will tend to underestimate the real-world benefits of fuel economy and emissions standards. By including several simple driver and vehicle attributes, the Individualized Model reduces the unexplained variance by over 55% and the standard error by 33% based on an independent test sample. The additional explanatory variables can be easily provided by the individuals.

    In "The (unfortunate) complexity of the economy" (April pp28-32) Jean-Philippe Bouchaud presents clear evidence that traditional assumptions of rational markets have to be abandoned. The old investor slogan "buy on promise, sell on rumour" quickly magnifies a downturn into a crisis, which triggers two questions. If physics-based models are applied (beyond understanding and prediction) to actual market decisions, does this make the economy more or less stable? And, is this cause for stronger regulation?

    2010-10-01

    In developed economies, the sign of the price increment influences the volatility in an asymmetric fashion—negative increments tend to result in larger volatility (increments with larger magnitudes), while positive increments result in smaller volatility. We explore whether this asymmetry extends from developed economies to European transition economies and, if so, how such asymmetry changes over time as these transition economies develop and mature. We analyze eleven European transition economies and compare the results with those obtained by analyzing U.S. market indices. Specifically, we calculate parameters that quantify both the volatility asymmetry and the strength of its dependence on prior increments. We find that, like their developed economy counterparts, almost all transition economy indices exhibit a significant volatility asymmetry, and the parameter γ characterizing asymmetry fluctuates more over time for transition economies. We also investigate how the association between volatility and volatility asymmetry varies by type of market. We test the hypothesis of a negative correlation between volatility and volatility asymmetry. We find that, for developed economies, γ experiences local minima during (i) “Black Monday” on October 19, 1987, (ii) the dot-com bubble crash in 2002, and (iii) the 2007-2009 global crisis while for transition economies, γ experiences local maxima during times of economic crisis.

  15. The real new economy.

    Farrell, Diana

    2003-10-01

    During the soar-and-swoon days of the late 1990s, many people believed that information technology, and the Internet in particular, were "changing everything" in business. A fundamental change did happen in the 1990s, but it was less about technology than about competition. Under director Diana Farrell, the McKinsey Global Institute has conducted an extensive study of productivity and its connection to corporate IT spending and use during that period. The study revealed that information technology is important--but not central--to the fate of industries and individual companies. So if information technology was not the primary factor in the productivity surge, what was? The study points to competition and innovation. In those industries that saw increases in competitive intensity, managers were forced to innovate aggressively to protect their revenues and profits. Those innovations--in products, business practices, and technology--led to the gains in productivity. In fact, a critical dynamic of the new economy--the real new economy--is the virtuous cycle of competition, innovation, and productivity growth. Managers can innovate in many ways, but during the 1990s, information technology was a particularly powerful tool, for three reasons: First, IT enabled the development of attractive new products and efficient new business processes. Second, it facilitated the rapid industrywide diffusion of innovations. And third, it exhibited strong scale economies--its benefits multiplied rapidly as its use expanded. This article reveals surprising data on how various industries in the United States and Europe were affected by competition, innovation, and information technology in the 1990s and offers insights about how managers can get more from their IT investments.

    The customary treatment of national economies as closed and self-contained must be substantially modified to allow for those economies that typically trade goods, services, and securities with other countries in increasing volume. Open economy macroeconomics is essential to understanding the major events of the U.S. economy over the past half dozen years. Both the sharp rise in the dollar and the unprecedentedly large U.S. trade deficit are linked to the U.S. budget deficit, as is the drop in the rate of inflation. PMID:17756868

  5. Climate and Air Quality Impact of a Hydrogen Economy

    2008-12-01

    It is imperative to fully analyze the risks and benefits of policy decisions before they are implemented, particularly given the past adverse global impacts of anthropogenic emissions, e.g., CFCs and their impact on stratospheric ozone. An interesting "what if" question is what would be the potential environmental impacts if the U.S. were to transition from a fossil fuel based energy system to a society heavily dependent on hydrogen based transportation. We focus on systematically examining and identifying possible near- and long-term ecological, environmental, and climate effects of the large-scale production and use of hydrogen in transportation and power applications examining both the direct and indirect effects. We use the IPCC 2050 A1FI SRES emissions scenario as a baseline and develop alternative H2 adoption emissions scenarios as perturbations to this baseline. The perturbation scenarios include various combinations of enhanced H2 emissions and reductions of VOC, NOx, and SOx emissions. Three-dimensional CAM-Chem model simulations suggest that for a complete transition to hydrogen-based energy and transportation systems the tropospheric H2 burden would increase substantially, as much as 7.7 times the baseline. There would also be significant decreases in tropospheric OH and ozone. Summer mean surface ozone concentrations over the continental U.S. would decrease by as much as 35 ppb, largely due to the net reduction in emissions of nitrogen oxides and hydrocarbons. Simulations also suggest that these results are sensitive to the dependence of soil H2 uptake on atmospheric H2 concentrations

    The benefits, safety, production, distribution, storage, and uses, as well as the economics of a solar and hydrogen based U.S. energy system are described. Tropical and subtropical locations for the generation plants would provide power from photovoltaics, heliostat arrays, OTEC plants, or genetically engineered algae to produce hydrogen by electrolysis, direct thermal conversion, thermochemical reactions, photolysis, or hybrid systems. Either pipelines for gas transport or supertankers for liquefied hydrogen would distribute the fuel, with storage in underground reservoirs, aquifers, and pressurized bladders at sea. The fuel would be distributed to factories, houses, gas stations, and airports. It can be used in combustion engines, gas turbines, and jet engines, and produces water vapor as an exhaust gas. The necessary research effort to define and initiate construction of technically and economically viable solar-hydrogen plants is projected to be 3 yr, while the technical definition of fusion power plants, the other nondepletable energy system, is expected to take 25 yr.

    Hydrogen will assume a key role in Europe's effort to adopt its energy dependent society to satisfy its needs without releasing vast amounts of greenhouse gases. The paradigm shift is so paramount that one speaks of the "Hydrogen Economy", as the energy in this new and ecological type of economy is to be distributed by hydrogen. However, H2 is not a primary energy source but rather an energy carrier, a means of storing, transporting and distributing energy, which has to be generated by other means. Various H2 storage methods are possible; however industries' favourite is the storage of gaseous hydrogen in high pressure tanks. The biggest promoter of this storage methodology is the automotive industry, which is currently preparing for the generation change from the fossil fuel internal combustion engines to hydrogen based fuel cells. The current roadmaps foresee a market roll-out by 2015, when the hydrogen supply infrastructure is expected to have reached a critical mass. The hydrogen economy is about to take off as being demonstrated by various national mobility strategies, which foresee several millions of electric cars driving on the road in 2020. Fuel cell cars are only one type of "electric car", battery electric as well as hybrid cars - all featuring electric drive trains - are the others. Which type of technology is chosen for a specific application depends primarily on the involved energy storage and power requirements. These considerations are very similar to the ones in the aerospace sector, which had introduced the fuel cell already in the 1960s. The automotive sector followed only recently, but has succeeded in moving forward the technology to a level, where the aerospace sector is starting considering to spin-in terrestrial hydrogen technologies into its technology portfolio. Target areas are again high power/high energy applications like aviation, manned spaceflight and exploration missions, as well as future generation high power telecommunication

    1983-01-10

    The potential for improved automibile fuel economy as part of the California Energy Commission's transportation fuel demand forecasting effort is evaluated. Such forecasts are required by state law. Various industry and research sources are surveyed to determine the expected time frame and fuel economy impact of advanced technologies. Technical areas addressed include: automobile aerodynamics, tire rolling resistance, transmission efficiencies, vehicle weight, and engine efficiencies. Technical improvements in these areas are projected to result in the following fuel economy gains over 1980 levels: gasoline engine efficiency - 25 percent, diesel engine efficiency - 8 to 18 percent, transmission efficiency - 4 percent, weight reduction - 20 to 27 percent, aerodynamic drag reduction - 7 percent, and rolling resistance reduction - 5 percent. It is concluded that technical improvments in these areas can result in the average car achieving 45 miles per gallon by the year 2002.

    benefits and costs of hydrogen-based alternatives, H2POWER compares the financial and socioeconomic costs of home and neighborhood refueling units to a baseline of "conventional" sources of residential electricity, space heat, water heat, and vehicle fuel. The model can also calculate the "gap" between the financial cost of the technology and the environmental cost of the externalities that are generated using conventional energy sources. H2POWER is a flexible, user-friendly tool that allows the user to specify different production pathways, supplemental power sources (renewable and non-renewable), component characteristics, electricity mixes, and other analysis parameters in order to customize the results to specific projects. The model has also built-in default values for each of the input fields based on national averages, standard technology specifications and input from experts.

  14. The symbolic economy of drugs.

    PubMed

    Lentacker, Antoine

    2016-02-01

    This essay reviews four recent studies representing a new direction in the history of pharmaceuticals and pharmaceutical science. To this end, it introduces the notion of a symbolic economy of drugs, defined as the production, circulation, and reception of signs that convey information about drugs and establish trust in them. Each of the studies under review focuses on one key signifier in this symbolic economy, namely the brand, the patent, the clinical trial, and the drug itself. Drawing on Pierre Bourdieu's theory of the economy of symbolic goods, I conceptualize these signifiers as symbolic assets, that is, as instruments of communication and credit, delivering knowledge, carrying value, and producing authority. The notion of a symbolic economy is offered with a threefold intention. First, I introduce it in order to highlight the implications of historical and anthropological work for a broader theory of the economy of drugs, thus suggesting a language for interdisciplinary conversations in the study of pharmaceuticals. Second, I deploy it in an attempt to emphasize the contributions of the recent scholarship on drugs to a critical understanding of our own contemporary ways of organizing access to drugs and information about drugs. Finally, I suggest ways in which it might be of use to scholars of other commodities and technologies. PMID:26983175

With introduction of market economy in Central and Eastern Europe, the radiation processing has lost doubtful support, becoming an independent business, subject to laws of free market economy. Only the most valuable objects of processing have survived that test. At the top of the list are: radiation sterilization of medical equipment and radiation induced crosslinking of polymers, polyethylene in particular. New elements of competition has entered the scene, as well as questions of international regulations and standards have appeared.

    The ability to lower GHG emissions by 80% from current levels - the 'ecological target' is already possible in the stationary power sector through strategies that include efficiency, renewable energy, and nuclear power. For light vehicle transportation, mileage standards, biofuels, and engine technology will play critical roles to drastically reduce emissions. Air travel remains problematic and in dire need of additional innovations. Advanced energy storage technologies coupled with affordable renewable energy sources could potentially eliminate emissions for both stationary power and vehicles. Given the cost curves of key energy technologies, our analysis for the US economy shows that deploying emissions abating options is not only cost effective, it also affords enormous socioeconomic and environmental returns.

    1981-12-01

    The possibilities of total conversion to a world hydrogen-based economy is discussed, noting that economically retrievable coal reserves will be depleted by 2033, at which time a 2-4 C rise in the world atmospheric temperature will have resulted. The removal of large coal, nuclear, and windpowered central generating plants to offshore locations, and solar thermal plants to remote, sunny locations, along with large photovoltaic installations, is recommended as a means of ameliorating the nuissances and dangers of building such facilities near populations. The removal of energy-producing centers from populated areas necessitates long-distance energy transmission, which is noted to be achievable by employing hydrogen gas in natural gas-type transmission pipes. The hydrogen could be produced electrolytically, and an effort during the 1980's to found a common hydrogen pipeline between France and Germany is mentioned.

  19. Political economy of population growth.

    PubMed

    Mehta, S; Mehta, H S

    1987-01-01

    Tracing the origin of political economy as a class-science, this paper focuses on the political economy of population growth. Exposing the limitations of Malthusian ideas and their invalidity even for the capitalist economies, it discusses the subsequent revival of the Malthusian model during the period of de-colonization and the misinterpretation of the relationship between population growth and development in the developing and developed countries. Taking India, China, and Japan as some case studies, the paper examines the relationship between birth rate levels and some correlates. It elaborates on the Indian experience, emphasizing the association of population growth with poverty and unemployment and lays bare some of the hidden causes of these phenomena. The authors examine some interstate variations in India and identify constraints and prospects of the existing population policy. The paper proposes outlines of a democratic population policy as an integral part of India's development strategy which should recognize human beings not simply as consumers but also as producers of material values. It pleads for 1) restructuring of property relations; 2) bringing down the mortality rates and raising of the literacy levels, especially among females; and 3) improving nutritional levels, as prerequisites for bringing down birth rates.

  20. Population and the Colombian economy.

    PubMed

    Sanders, T G

    1983-01-01

    Colombia is the only one of the 6 most populous Latin American countries that is currently free of major economic crisis requiring an agreement with the International Monetary Fund. The difference in the economic performances of these countries is relative, since the rate of growth in the Colombian economy was only 1.5% in 1982. Yet, Colombia seems to have weathered the international recession better than most. The crisis atmosphere in the rest of Latin America, triggered by overall economic decline, high rates of inflation, and an indebtedness that soaks up much of export earnings to service it, is lacking in Colombia or present in lesser degree. If Colombia can strengthen its political performance and tighten national unity, it could move through the 1980s with considerable confidence and success in economic development. Colombia differs little from other major Latin American countries with regard to traditionalism and modernization. Most Colombians are secularized. Colombia is far ahead of most comparable Latin American countries in fertility control. The lower rate of population increase defines the extent to which the economy must provide education, health, food, and jobs. 2 other factors are essential for understanding the current situation in Colombia and its prospects for the 1980s. Government policy in the 1970s opted for an austerity program while the other countries were growing rapidly, in large part through borrowed resources. A 2nd factor is the prospect of attaining autonomy in energy production. These special characteristics--population, public policy, and energy--are discussed. Since the mid 1960s Colombia has functioned with 3 family planning programs. Their existence makes contraception easily available to the population generally. In 1960 Colombia had a higher total fertility rate (TFR) 7.0, than either Venezuela (6.6) or Brazil (5.3), but by 1976 its TFR was down to 4.1, while Venezuela's (4.8) and Brazil's (4.3) were now higher.

  1. Strategies to improve running economy.

    PubMed

    Barnes, Kyle R; Kilding, Andrew E

    2015-01-01

    Running economy (RE) represents a complex interplay of physiological and biomechanical factors that is typically defined as the energy demand for a given velocity of submaximal running and expressed as the submaximal oxygen uptake (VO2) at a given running velocity. This review considered a wide range of acute and chronic interventions that have been investigated with respect to improving economy by augmenting one or more components of the metabolic, cardiorespiratory, biomechanical or neuromuscular systems. Improvements in RE have traditionally been achieved through endurance training. Endurance training in runners leads to a wide range of physiological responses, and it is very likely that these characteristics of running training will influence RE. Training history and training volume have been suggested to be important factors in improving RE, while uphill and level-ground high-intensity interval training represent frequently prescribed forms of training that may elicit further enhancements in economy. More recently, research has demonstrated short-term resistance and plyometric training has resulted in enhanced RE. This improvement in RE has been hypothesized to be a result of enhanced neuromuscular characteristics. Altitude acclimatization results in both central and peripheral adaptations that improve oxygen delivery and utilization, mechanisms that potentially could improve RE. Other strategies, such as stretching should not be discounted as a training modality in order to prevent injuries; however, it appears that there is an optimal degree of flexibility and stiffness required to maximize RE. Several nutritional interventions have also received attention for their effects on reducing oxygen demand during exercise, most notably dietary nitrates and caffeine. It is clear that a range of training and passive interventions may improve RE, and researchers should concentrate their investigative efforts on more fully understanding the types and mechanisms that

    This report looks at Bolivia's main economic indicators over the past year (mid-2006 to mid-2007), noting improvements in growth, fiscal balances, balance of payments, and international reserves. These improvements were largely due to government policies and choices, such as increased hydrocarbons royalties and control over the hydrocarbons sector, and have allowed the government to embark on a number of programs targeting the poor and landless. The report also notes that Bolivia faces many challenges: expansion of land reform, more rapid growth and poverty reduction, the reduction of regional and demographic disparities, and an accelerated diversification of the economy away from hydrocarbons and minerals.

  3. On sustainable development of population and national economy.

    PubMed

    Tian, X

    1995-01-01

    This article offers a strategy for achieving sustainable development of population and the national economy in China. It is argued that economic growth and population growth must be in balance and coordinated. In 1993 it was estimated that a national economic growth rate of 4.03-4.60% was needed in order to balance the natural population growth rate of 1.15% at the existing standard of living. When the national economy grows faster than population in the life expectancy time period, overpopulation can be checked. Population must be balanced with sufficient means for subsistence. The key measure of sustainable development is the ratio between the size of the working-age population and the means of production. The number of people in the labor force is positively related to fixed assets and negatively related to the labor force's technical equipment. China's problems include weak industrial fixed assets, a surplus labor force, and slow growth in industrial and agricultural productivity. Potential solutions are to shift employment from a cultivation-oriented rural economy to a diversified rural economy, to increase the pace of change to an industrial and commercial economy, and to increase the pace of change to nonmaterial production and to raising employment efficiency. Solutions are dependent upon improvement in the quality of population, which means increased levels of education. China still has 181,610,00 people who are illiterate or semi-illiterate among the working-age population. Sustainable development also relies on active promotion of social support for the elderly by a pension system, family support, and reemployment of the elderly. Surplus labor should be absorbed by the service industry. Population structure and economic development are more advanced in coastal areas that have 41% of total population. Inland areas should develop labor-intensive, technology-intensive, and investment-intensive industries. Northwest areas need an educated population

    Introduction: Health Information Economy (HIE) is one of the broader, more complex, and challenging and yet important topics in the field of health science that requires the identification of its dimensions for planning and policy making. The aim of this study was to determine HIE concept dimensions. Methods: This paper presents a systematic methodology for analyzing the trends of HIE. For this purpose, the main keywords of this area were identified and searched in the databases and from among 4775 retrieved sources, 12 sources were studied in the field of HIE. Results: Information Economy (IE) in the world has passed behind four paradigms that involve the information evaluation perspective, the information technology perspective, the asymmetric information perspective and information value perspective. In this research, the fourth perspective in the HIE was analyzed. The main findings of this research were categorized in three major groups, including the flow of information process in the field of health (production. collection, processing and dissemination), and information applications in the same field (education, research, health industry, policy, legislation, and decision-making) and the underlying fields. Conclusion: According to the findings, HIE has already developed a theoretical and conceptual gap that due to its importance in the next decade would be one of the research approaches to health science.

  5. Health benefits of a low carbon economy.

    PubMed

    Haines, A

    2012-09-01

    This article summarizes a presentation given at 'Health and Well-being: the 21st Century Agenda', which focused on the potential to make progress by making appropriate connections between activity to promote health and respond to the threat of climate change. It argues that a transition to a low carbon economy would bring together two of our greatest public health challenges, supporting action to improve public health within resource constraints and action to avert climate change as far as possible. Deep cuts in emissions are needed to prevent dangerous consequences arising from climate change. In addition, many of the policies to reduce greenhouse gas emissions will, in themselves, have beneficial effects on public health. This article provides an overview of several modelling studies which demonstrate that well-designed initiatives that curb greenhouse gas emissions in energy, residential construction, urban transport and agricultural systems can enhance global public health, including improving health among poor populations. Some of these health co-benefits can be achieved in a relatively short time frame, and they can help offset the costs of climate change mitigation policies. PMID:22784582

  6. Analysis of the holistic impact of the Hydrogen Economy on the coal industry

    NASA Astrophysics Data System (ADS)

    Lusk, Shannon Perry

    As gas prices soar and energy demand continues to grow amidst increasingly stringent environmental regulations and an assortment of global pressures, implementing alternative energy sources while considering their linked economic, environmental and societal impacts becomes a more pressing matter. The Hydrogen Economy has been proposed as an answer to meeting the increasing energy demand for electric power generation and transportation in an environmentally benign way. Based on current hydrogen technology development, the most practical feedstock to fuel the Hydrogen Economy may prove to be coal via hydrogen production at FutureGen plants. The planned growth of the currently conceived Hydrogen Economy will cause dramatic impacts, some good and some bad, on the economy, the environment, and society, which are interlinked. The goal of this research is to provide tools to inform public policy makers in sorting out policy options related to coal and the Hydrogen Economy. This study examines the impact of a transition to a Hydrogen Economy on the coal industry by creating FutureGen penetration models, forecasting coal MFA's which clearly provide the impact on coal production and associated environmental impacts, and finally formulating a goal programming model that seeks the maximum benefit to society while analyzing the trade-offs between environmental, social, and economical concerns related to coal and the Hydrogen Economy.

  7. Reviving the carbohydrate economy via multi-product lignocellulose biorefineries.

    PubMed

    Zhang, Y-H Percival

    2008-05-01

    Before the industrial revolution, the global economy was largely based on living carbon from plants. Now the economy is mainly dependent on fossil fuels (dead carbon). Biomass is the only sustainable bioresource that can provide sufficient transportation fuels and renewable materials at the same time. Cellulosic ethanol production from less costly and most abundant lignocellulose is confronted with three main obstacles: (1) high processing costs (dollars /gallon of ethanol), (2) huge capital investment (dollars approximately 4-10/gallon of annual ethanol production capacity), and (3) a narrow margin between feedstock and product prices. Both lignocellulose fractionation technology and effective co-utilization of acetic acid, lignin and hemicellulose will be vital to the realization of profitable lignocellulose biorefineries, since co-product revenues would increase the margin up to 6.2-fold, where all purified lignocellulose co-components have higher selling prices (> approximately 1.0/kg) than ethanol ( approximately 0.5/kg of ethanol). Isolation of large amounts of lignocellulose components through lignocellulose fractionation would stimulate R&D in lignin and hemicellulose applications, as well as promote new markets for lignin- and hemicellulose-derivative products. Lignocellulose resource would be sufficient to replace significant fractionations (e.g., 30%) of transportation fuels through liquid biofuels, internal combustion engines in the short term, and would provide 100% transportation fuels by sugar-hydrogen-fuel cell systems in the long term.

    The role of the Chief Information Officer (CIO) has evolved considerably since its inception in the 1980s. This paper begins with a brief review of the evolution of this role and sets the stage for future change brought about by the rise of the service economy. The enterprise of the future is then characterized based on an important global study by IBM. Using this characterization, the future challenges for CIOs in areas such as strategic planning, governance and operations management of information technology services are assessed from the perspectives of the four major elements of a service system (technology, people, organization and shared information). The paper concludes with a summary of the important findings, pointing to the challenge that CIOs of the future must be the leaders in their organizations in the delivery of smarter, on-demand service systems to smarter customers.

    This research investigates the possibilities of potential savings and reduction in Green House Gas (GHG) emissions caused by road transport in general and private cars in particular. Private cars use a large share of the transport fuel, thus these are the major and ever increasing contributor to the GHG emissions. An extensive review of international experiences on fuel economy standards and labels, in order to encounter the problem, is carried. The possibilities of the implementation of fuel economy standards and labels for motor vehicles in Pakistan are examined. Based on the studies carried out in developed countries, results have shown that the implementation of fuel economy standards and labels for motor vehicles in developing countries like Pakistan would be beneficial for the society, government as well as environment.

  13. The Sustainable Hydrogen Economy: Addressing the Challenges Ahead

    NASA Astrophysics Data System (ADS)

    Turner, John A.

    2006-10-01

    It is rapidly becoming apparent that energy is one of the most important issues facing our world today; in fact, in today's society energy is as important as food and water. Humankind finds itself faced the challenge of how to continue to power society, particularly in the face of the rapidly growing economies of emerging nations like India and China, and yet answer questions of sustainability, energy security, geopolitics and global environment. One of the major issues facing America and most other countries in the world is how to supply a transportation fuel, an energy carrier to replace gasoline. Hydrogen as an energy carrier, primarily derived from water, can address issues of sustainability, environmental emissions and energy security. The ``Hydrogen Economy'' then is the production of hydrogen, its distribution and utilization as an energy carrier. While the vision of a hydrogen economy has been around for over 130 years, the most recent push to use hydrogen as an energy carrier came as part of a US Presidential Initiative, announced in the 2003 State of the Union Address. It is important that we consider hydrogen in tandem with other technologies as an alternative to the once-abundant hydrocarbon resources on which our society depends. This talk will introduce sustainable energy systems, including fuel cell technology and discuss the vision, the barriers and possible pathways for the production and implementation of hydrogen into the energy infrastructure.

  6. The Informal Economy: Recent Trends, Future Directions.

    PubMed

    Chen, Martha Alter

    2016-08-01

    Informal employment represents more than half of nonagricultural employment in most developing regions, contributes to the overall economy, and provides pathways to reduction of poverty and inequality. Support to the informal economy should include the expansion of occupational health and safety to include informal workers, based on an analysis of their work places and work risks. The paper presents main schools of thought and argues for a holistic understanding of the different segments of the informal work force and for policies and interventions tailored to the needs and constraints of these different segments. The paper recommends a policy approach which seeks to extend social protection, including occupational health and safety services, to informal workers, and to increase the productivity of informal enterprises and informal workers through an enabling environment and support services. The paper calls for a new paradigm of a hybrid economy which would value and integrate the informal economy alongside the formal economies. PMID:27252281

    After decades of futile attempts to increase U.S. fuel economy standards for passenger cars, which have remained unchanged since enactment of the Corporate Average Fuel Economy (CAFE) Standards in Title V of the 1975 Energy Policy Conservation Act, it seems increasingly likely that new and tougher standards will be enacted in the near future - especially after the Senate's 21 June passage of energy efficiency bill H.R. 6. As this magazine went to press, the bill, which calls for a 40 percent increase in vehicle fuel economy by 2020 among other efficiency and alternative energy goals, was headed to the House of Representatives for more debate. Congress has seen proposals like this since the 1980s, but this is the first time that one of them has passed in the Senate. The Bush administration has also weighed in with a proposal to increase new vehicle fuel economy by 4 percent per year from 2011 to 2017, and the administrator of the National Highway Traffic Safety Administration (NHTSA) has asked Congress to grant the Secretary of Transportation the authority to restructure and increase CAFE standards for cars, a power denied by the original CAFE legislation. A confluence of events has led to this change of political climate, including: the failure of world oil production and refining capacity to keep pace with rapidly growing demand, especially from China and other emerging economies, which has led to the highest oil prices since the 1980s and growing fears that world production of conventional oil may be close to its peak and rapid decline; the escalating influence of oil resources on geopolitics as China seeks to guarantee its future access to supplies, enhanced revenues from the higher prices, which prop up authoritarian regimes in Iran, Venezuela, Russia, and elsewhere and allow them increasing freedom of action; the enhancement of the role of climate change in political decision making by new reports from the Intergovernmental Panel on Climate Change (IPCC), with

  11. Fuel Cell System for Transportation -- 2005 Cost Estimate

    SciTech Connect

    Wheeler, D.

    2006-10-01

    Independent review report of the methodology used by TIAX to estimate the cost of producing PEM fuel cells using 2005 cell stack technology. The U.S. Department of Energy (DOE) Hydrogen, Fuel Cells and Infrastructure Technologies Program Manager asked the National Renewable Energy Laboratory (NREL) to commission an independent review of the 2005 TIAX cost analysis for fuel cell production. The NREL Systems Integrator is responsible for conducting independent reviews of progress toward meeting the DOE Hydrogen Program (the Program) technical targets. An important technical target of the Program is the proton exchange membrane (PEM) fuel cell cost in terms of dollars per kilowatt ($/kW). The Program's Multi-Year Program Research, Development, and Demonstration Plan established $125/kW as the 2005 technical target. Over the last several years, the Program has contracted with TIAX, LLC (TIAX) to produce estimates of the high volume cost of PEM fuel cell production for transportation use. Since no manufacturer is yet producing PEM fuel cells in the quantities needed for an initial hydrogen-based transportation economy, these estimates are necessary for DOE to gauge progress toward meeting its targets. For a PEM fuel cell system configuration developed by Argonne National Laboratory, TIAX estimated the total cost to be $108/kW, based on assumptions of 500,000 units per year produced with 2005 cell stack technology, vertical integration of cell stack manufacturing, and balance-of-plant (BOP) components purchased from a supplier network. Furthermore, TIAX conducted a Monte Carlo analysis by varying ten key parameters over a wide range of values and estimated with 98% certainty that the mean PEM fuel cell system cost would be below DOE's 2005 target of $125/kW. NREL commissioned DJW TECHNOLOGY, LLC to form an Independent Review Team (the Team) of industry fuel cell experts and to evaluate the cost estimation process and the results reported by TIAX. The results of this

  12. Quantifying the vitamin D economy.

    Heaney, Robert P; Armas, Laura A G

    2015-01-01

    Vitamin D enters the body through multiple routes and in a variety of chemical forms. Utilization varies with input, demand, and genetics. Vitamin D and its metabolites are carried in the blood on a Gc protein that has three principal alleles with differing binding affinities and ethnic prevalences. Three major metabolites are produced, which act via two routes, endocrine and autocrine/paracrine, and in two compartments, extracellular and intracellular. Metabolic consumption is influenced by physiological controls, noxious stimuli, and tissue demand. When administered as a supplement, varying dosing schedules produce major differences in serum metabolite profiles. To understand vitamin D's role in human physiology, it is necessary both to identify the foregoing entities, mechanisms, and pathways and, specifically, to quantify them. This review was performed to delineate the principal entities and transitions involved in the vitamin D economy, summarize the status of present knowledge of the applicable rates and masses, draw inferences about functions that are implicit in these quantifications, and point out implications for the determination of adequacy.

  13. Paraguay: population and the economy.

    PubMed

    Sanders, T G

    1986-01-01

    Paraguay's political conflicts and development experiences have been accompanied by compensatory population movements; however, economic and population policies of the past are not adequate to address the current economic challenges. The principal structural problem is dependence on international commodity prices. Since late 1984, the international prices for soya and cotton have declined more than 50%; these 2 products account for 83% of official exports. The external debt has grown significantly in the past 5 years and is increasingly difficult to service. A major problem the government faces in servicing the debt and maintaining economic growth is its inability to get control of foreign exchange. Much of Paraguay's external trade is contraband, with the dollars passing into the black market. As a result of the illegal economy, government earnings have been insufficient to cover expenses. Unemployment stands at 12% because of general economic decline, cuts in government expenditure, and the reduction of investment in hydroelectricity. Occupation of new land, the classic solution by the Paraguayan peasantry, is no longer a viable option since all land is now utilized. About 20-25% of Paraguayans live outside the country, expecially in Argentina. In 1986, a commission drafted an Adjustment Plan that recommended a devaluation of the official gurani rate, tax increases, higher tariffs for public services, and incentives to invest in priority areas; however, this plan has not been implemented to date.

  14. Energy-economy interactions revisited within a comprehensive sectoral model

    SciTech Connect

    Hanson, D. A.; Laitner, J. A.

    2000-07-24

    This paper describes a computable general equilibrium (CGE) model with considerable sector and technology detail, the ``All Modular Industry Growth Assessment'' Model (AMIGA). It is argued that a detailed model is important to capture and understand the several rolls that energy plays within the economy. Fundamental consumer and industrial demands are for the services from energy; hence, energy demand is a derived demand based on the need for heating, cooling mechanical, electrical, and transportation services. Technologies that provide energy-services more efficiently (on a life cycle basis), when adopted, result in increased future output of the economy and higher paths of household consumption. The AMIGA model can examine the effects on energy use and economic output of increases in energy prices (e.g., a carbon charge) and other incentive-based policies or energy-efficiency programs. Energy sectors and sub-sector activities included in the model involve energy extraction conversion and transportation. There are business opportunities to produce energy-efficient goods (i.e., appliances, control systems, buildings, automobiles, clean electricity). These activities are represented in the model by characterizing their likely production processes (e.g., lighter weight motor vehicles). Also, multiple industrial processes can produce the same output but with different technologies and inputs. Secondary recovery, i.e., recycling processes, are examples of these multiple processes. Combined heat and power (CHP) is also represented for energy-intensive industries. Other modules represent residential and commercial building technologies to supply energy services. All sectors of the economy command real resources (capital services and labor).

    2014-01-01

    Substantial inter-individual variations in exercise economy exist even in highly trained endurance athletes. The variation is believed to be determined partly by intrinsic factors. Therefore, in the present study, we compared exercise economy in V2-skating, double poling, and uphill running. Ten highly trained male cross-country skiers (23 ± 3 years, 180 ± 6 cm, 75 ± 8 kg, VO2peak running: 76.3 ± 5.6 mL·kg−1·min−1) participated in the study. Exercise economy and VO2peak during treadmill running, ski skating (V2 technique) and double poling were compared based on correlation analysis. There was a very large correlation in exercise economy between V2-skating and double poling (r = 0.81) and large correlations between V2-skating and running (r = 0.53) and double poling and running (r = 0.58). There were trivial to moderate correlations between exercise economy and the intrinsic factors VO2peak (r = 0.00–0.23), cycle rate (r = 0.03–0.46), body mass (r = −0.09–0.46) and body height (r = 0.11–0.36). In conclusion, the inter-individual variation in exercise economy could be explained only moderately by differences in VO2peak, body mass and body height. Apparently other intrinsic factors contribute to the variation in exercise economy between highly trained subjects. PMID:24478718

  16. Welcome to the experience economy.

    PubMed

    Pine, B J; Gilmore, J H

    1998-01-01

    First there was agriculture, then manufactured goods, and eventually services. Each change represented a step up in economic value--a way for producers to distinguish their products from increasingly undifferentiated competitive offerings. Now, as services are in their turn becoming commoditized, companies are looking for the next higher value in an economic offering. Leading-edge companies are finding that it lies in staging experiences. To reach this higher level of competition, companies will have to learn how to design, sell, and deliver experiences that customers will readily pay for. An experience occurs when a company uses services as the stage--and goods as props--for engaging individuals in a way that creates a memorable event. And while experiences have always been at the heart of the entertainment business, any company stages an experience when it engages customers in a personal, memorable way. The lessons of pioneering experience providers, including the Walt Disney Company, can help companies learn how to compete in the experience economy. The authors offer five design principles that drive the creation of memorable experiences. First, create a consistent theme, one that resonates throughout the entire experience. Second, layer the theme with positive cues--for example, easy-to-follow signs. Third, eliminate negative cues, those visual or aural messages that distract or contradict the theme. Fourth, offer memorabilia that commemorate the experience for the user. Finally, engage all five senses--through sights, sounds, and so on--to heighten the experience and thus make it more memorable.

  20. Fuel economy of hydrogen fuel cell vehicles

    NASA Astrophysics Data System (ADS)

    Ahluwalia, Rajesh K.; Wang, X.; Rousseau, A.; Kumar, R.

    On the basis of on-road energy consumption, fuel economy (FE) of hydrogen fuel cell light-duty vehicles is projected to be 2.5-2.7 times the fuel economy of the conventional gasoline internal combustion engine vehicles (ICEV) on the same platforms. Even with a less efficient but higher power density 0.6 V per cell than the base case 0.7 V per cell at the rated power point, the hydrogen fuel cell vehicles are projected to offer essentially the same fuel economy multiplier. The key to obtaining high fuel economy as measured on standardized urban and highway drive schedules lies in maintaining high efficiency of the fuel cell (FC) system at low loads. To achieve this, besides a high performance fuel cell stack, low parasitic losses in the air management system (i.e., turndown and part load efficiencies of the compressor-expander module) are critical.

    The Transportation Energy Data Book: Edition 11 is a statistical compendium prepared and published by Oak Ridge National Laboratory (ORNL) under contract with the Office of Transportation Technologies in the Department of Energy (DOE). Designed for use as a desk-top reference, the data book represents an assembly and display of statistics and information that characterize transportation activity, and presents data on other factors that influence transportation energy use. The purpose of this document is to present relevant statistical data in the form of tables and graphs. Each of the major transportation modes - highway, air, water, rail, pipeline - is treated in separate chapters or sections. Chapter 1 compares U.S. transportation data with data from seven other countries. Aggregate energy use and energy supply data for all modes are presented in Chapter 2. The highway mode, which accounts for over three-fourths of total transportation energy consumption, is dealt with in Chapter 3. Topics in this chapter include automobiles, trucks, buses, fleet automobiles, Federal standards, fuel economies, and household data. Chapter 4 is a new addition to the data book series, containing information on alternative fuels and alternatively-fueled vehicles. The last chapter, Chapter 5, covers each of the nonhighway modes: air, water, pipeline, and rail, respectively.

  3. Our Lunar Destiny: Creating a Lunar Economy

    NASA Astrophysics Data System (ADS)

    Rohwer, Christopher J.

    2000-01-01

    "Our Lunar Destiny: Creating a Lunar Economy" supports a vision of people moving freely and economically between the earth and the Moon in an expansive space and lunar economy. It makes the economic case for the creation of a lunar space economy and projects the business plan that will make the venture an economic success. In addition, this paper argues that this vision can be created and sustained only by private enterprise and the legal right of private property in space and on the Moon. Finally, this paper advocates the use of lunar land grants as the key to unleashing the needed capital and the economic power of private enterprise in the creation of a 21st century lunar space economy. It is clear that the history of our United States economic system proves the value of private property rights in the creation of any new economy. It also teaches us that the successful development of new frontiers-those that provide economic opportunity for freedom-loving people-are frontiers that encourage, respect and protect the possession of private property and the fruits of labor and industry. Any new 21st century space and lunar economy should therefore be founded on this same principle.

    The US transportation sector, which remains 97% dependent on petroleum, used a record 22.8 quads of energy in 1993. Though growing much more slowly than the economy from 1975 to 1985, energy use for transportation is now growing at nearly the same rate as GDP. This report describes the analysis of trends in energy use and energy intensity in transportation into components due to, (1) growth in transportation activity, (2) changes in energy intensity, and (3) changes in the modal structure of transportation activities.

    Research on several aspects of lunar transport using the hopping mode is reported. Hopping exploits the weak lunar gravity, permits fuel economy because of partial recompression of propellant gas on landing, and does not require a continuous smooth surface for operation. Three questions critical to the design of a lunar hopping vehicle are addressed directly in this report: (1) the tolerance of a human pilot for repeated accelerations; (2) means for controlling vehicle attitude during ballistic flight; and (3) means of propulsion. In addition, a small scale terrestrial demonstrator built to confirm feasibility of the proposed operational mode is described, along with results of preliminary study of unmanned hoppers for moon exploration.

  10. In-use fuel economy of hybrid-electric school buses in Iowa.

    PubMed

    Hallmark, Shauna; Sperry, Bob; Mudgal, Abhisek

    2011-05-01

    Although it is much safer and more fuel-efficient to transport children to school in buses than in private vehicles, school buses in the United States still consume 822 million gal of diesel fuel annually, and school transportation costs can account for a significant portion of resource-constrained school district budgets. Additionally, children in diesel-powered school buses may be exposed to higher levels of particulates and other pollutants than children in cars. One solution to emission and fuel concerns is use of hybrid-electric school buses, which have the potential to reduce emissions and overall lifecycle costs compared with conventional diesel buses. Hybrid-electric technologies are available in the passenger vehicle market as well as the transit bus market and have a track record indicating fuel economy and emissions benefits. This paper summarizes the results of an in-use fuel economy evaluation for two plug-in hybrid school buses deployed in two different school districts in Iowa. Each school district selected a control bus with a route similar to that of the hybrid bus. Odometer readings, fuel consumption, and maintenance needs were recorded for each bus. The buses were deployed in 2008 and data were collected through May 2010. Fuel consumption was calculated for each school district. In Nevada, IA, the overall average fuel economy was 8.23 mpg for the hybrid and 6.35 mpg for the control bus. In Sigourney, IA, the overall average fuel economy was 8.94 mpg for the hybrid and 6.42 mpg for the control bus. The fuel consumption data were compared for the hybrid and control buses using a Wilcoxon signed rank test. Results indicate that fuel economy for the Nevada hybrid bus was 29.6% better than for the Nevada control bus, and fuel economy for the Sigourney hybrid bus was 39.2% higher than for the Sigourney control bus. Both differences were statistically significant. PMID:21608490

  11. An entropic framework for modeling economies

    NASA Astrophysics Data System (ADS)

    Caticha, Ariel; Golan, Amos

    2014-08-01

    We develop an information-theoretic framework for economic modeling. This framework is based on principles of entropic inference that are designed for reasoning on the basis of incomplete information. We take the point of view of an external observer who has access to limited information about broad macroscopic economic features. We view this framework as complementary to more traditional methods. The economy is modeled as a collection of agents about whom we make no assumptions of rationality (in the sense of maximizing utility or profit). States of statistical equilibrium are introduced as those macrostates that maximize entropy subject to the relevant information codified into constraints. The basic assumption is that this information refers to supply and demand and is expressed in the form of the expected values of certain quantities (such as inputs, resources, goods, production functions, utility functions and budgets). The notion of economic entropy is introduced. It provides a measure of the uniformity of the distribution of goods and resources. It captures both the welfare state of the economy as well as the characteristics of the market (say, monopolistic, concentrated or competitive). Prices, which turn out to be the Lagrange multipliers, are endogenously generated by the economy. Further studies include the equilibrium between two economies and the conditions for stability. As an example, the case of the nonlinear economy that arises from linear production and utility functions is treated in some detail.

  12. Environmental issues elimination through circular economy

    Environmental efforts of European Union are currently going towards circular economy. Tools like Extended Producer Responsibility and Eco-design were established. The circular economy deals with resources availability issue on one hand and waste management on the other hand. There are few pioneering companies all over the world with some kind of circular economy practice. Generally the concept is not very wide-spread. The paper aims to evaluate possibility of transition towards circular economy in Slovak industrial companies. They need to have an active approach to material treatment of their products after usage stage. Innovation is another important pre-condition for the transition. Main problem of current cradle to grave system is landfilling of valuable materials after one cycle of usage. Their potential value for next manufacturing cycles is lost. Companies may do not see connection between waste management and material resource prices and volatility of supplies. Municipalities are responsible for municipal waste collection and treatment in Slovakia. The circular economy operates by cradle to cradle principle. Company manages material flow until the material comes back to the beginning of manufacturing process by itself or by another partners. Stable material supplies with quite low costs are provided this way. It is necessary to deal with environmental problems in phase of product design. Questionnaire survey results show on one hand low involvement of industrial companies in waste management area, however on the other hand they are open to environmental innovations in future.

  13. Motor vehicle fuel economy, the forgotten HC control stragegy?

    Emissions of hydrocarbons from motor vehicles are recognized as major contributors to ozone pollution in urban areas. Petroleum-based motor fuels contain volatile organic compounds (VOC) which, together with oxides of nitrogen, promote the formation of ozone in the troposphere via complex photochemical reactions. VOC emissions from the tailpipe and evaporation from the fuel and engine systems of highway vehicles are believed to account for about 40% of total VOC emissions in any region. But motor fuels also generate emissions throughout the fuel cycle, from crude oil production to refining, storage, transportation, and handling, that can make significant contributions to the total inventory of VOC emissions. Many of these sources of emissions are directly related to the quantity of fuel produced and handled throughout the fuel cycle. It is, therefore, reasonable to expect that a reduction in total fuel throughput might result in a reduction of VOC emissions. In particular, reducing vehicle fuel consumption by increasing vehicle fuel economy should reduce total fuel throughput, thereby cutting total emissions of VOCS. In this report we identify the sources of VOC emissions throughout the motor fuel cycle, quantify them to the extent possible, and describe their dependence on automobile and light truck fuel economy.

    Trofimov, S.; Kudzh, S.

    -called "topographical" approach, which is used by intellectual information technology "Dynamics of systems". According to it the realistic plan of regional economic system is created in the virtual space -directly on a computer desktop. And economic objects are displayed on evident schemes according to their real "geographical" structure. Each enterprise, bank, business-unit or the detached division of the company receives its own "Module" (area in working space of a spreadsheet). In result the general plan of regional economic system appears at planners. A whole real picture of all economic system functioning is recreated by such way. The idea of a method is obvious: the operator sees actual functioning of regional economy. This is promoted by "the friendly interface", allowing to display real objects as a clear symbols. The regional economy can be considered as a set of the separate enterprises connected by various economic communications. Constant monitoring of an infrastructure development, tracking of a cargoes transportation condition, supervision over following the ecological specifications by the regional enterprises, growth of housing and industrial building level, condition of communications, etc. is necessary for carrying out with the help of modern technologies of space shooting and satellite navigating systems. It will allow to obtain the data in an operative mode and will also help to the quickly modeling of a situation development variants, and to accept anticipatory administrative decisions. Other sources of the information are statistical directories and reports on a social condition in region: about a migration level and the population incomes, consumer's basket structure, demographic parameters - age of the capable population, a sexual and national attributes, etc. It is possible to attribute financial parameters to the third group: the regional budget condition data, a gain of investments into the regional economy, a growth of incomes in the regional budget from the

    Experimental data were generated to support an assessment of the relationship between automobile fuel economy and emissions control systems. Tests were made at both the engine and vehicle levels. Detailed investigations were made on cold-start emissions devices, exhaust gas recirculation systems, and air injection reactor systems. Based on the results of engine tests, an alternative emission control system and modified control strategy were implemented and tested in the vehicle. With the same fuel economy and NOx emissions as the stock vehicle, the modified vehicle reduced HC and CO emissions by about 20 percent. By removing the NOx emissions constraint, the modified vehicle demonstrated about 12 percent better fuel economy than the stock vehicle.

    1957-01-01

    The author deals with a wide variety of aspects of water economy and the development of water resources, relating them to the sanitary engineering problems they give rise to. Among those aspects are the balance between available resources and water needs for various purposes; accumulation and storage of surface and ground water, and methods of replenishing ground water supplies; pollution and purification; and organizational measures to deal with the urgent problems raised by the heavy demands on the world's water supply as a result of both increased population and the increased need for agricultural and industrial development. The author considers that at the national level over-all plans for developing the water economy of countries might well be drawn up by national water boards and that the economy of inter-State river basins should receive international study. In such work the United Nations and its specialized agencies might be of assistance. PMID:13472427

  17. Multidimensional modeling of biofilm development and fluid dynamics in a hydrogen-based, membrane biofilm reactor (MBfR).

    PubMed

    Martin, Kelly J; Picioreanu, Cristian; Nerenberg, Robert

    2013-09-01

    A two-dimensional, particle-based biofilm model coupled with mass transport and computational fluid dynamics was developed to simulate autotrophic denitrification in a spiral-wound membrane biofilm reactor (MBfR), where hydrogen is supplied via hollow-fiber membrane fabric. The spiral-wound configuration consists of alternating layers of plastic spacer net and membrane fabric that create rows of flow channels, with the top and bottom walls comprised of membranes. The transversal filaments of the spacer partially obstruct the channel flow, producing complex mixing and shear patterns that require multidimensional representation. This study investigated the effect of hydrogen and nitrate concentrations, as well as spacer configuration, on biofilm development and denitrification fluxes. The model results indicate that the cavity spacer filaments, which rest on the bottom membranes, cause uneven biofilm growth. Most biofilm resided on the bottom membranes, only in the wake of the filaments where low shear zones formed. In this way, filament configuration may help achieve a desired biofilm thickness. For the conditions tested in this study, the highest nitrate fluxes were attained by minimizing the filament diameter and maximizing the filament spacing. This lowered the shear stress at the top membranes, allowing for more biofilm growth. For the scenarios studied, biomass limitation at the top membranes hindered performance more significantly than diffusion limitation in the thick biofilms at the bottom membranes. The results also highlighted the importance of two-dimensional modeling to capture uneven biofilm growth on a substratum with geometrical complexity. PMID:23774188

    A vehicle`s in-use or on-the-road fuel economy often differs substantially from the miles-per-gallon estimates developed by the US Environmental Protection Agency (EPA) as part of its emissions certification program. As a result, the certification values are routinely adjusted by a set of correction factors so that the resulting estimates will better reflect in-use experience. Our analysis investigated how well the correction factors replicated the shortfall experience of all household vehicles on the road in 1985 and of those vehicles held by different population groups. Using data from the Residential Transportation Energy Consumption Survey conducted by the Energy Information Administration of the US Department of Energy, our analysis showed that fleetwide, the shortfall is larger than the EPA correction factors, and that light trucks are experiencing larger shortfalls than automobiles. Controlling for vehicle age and size class, shortfalls did not appear to differ by population group. However, African-American households appeared to select vehicles with systematically lower fuel economy (both EPA-test and on-the-road) within individual vehicle age and size class categories.

    The Leontief Input-Output economic system can provide a model for a one-parameter family of economic systems based on an abstract temperature T. In particular, given a normalized input-output matrix R and taking R= R(1), a family of economic systems R(1/T)=R(α) is developed that represents heating (T>1) and cooling (T<1) of the economy relative to T=1. .The economy for a given value of T represents the solution of a constrained maximum entropy problem.

    Inequality and its consequences are the subject of intense recent debate. Using a simplified model of the economy, we address the relation between inequality and liquidity, the latter understood as the frequency of economic exchanges. Assuming a Pareto distribution of wealth for the agents, that is consistent with empirical findings, we find an inverse relation between wealth inequality and overall liquidity. We show that an increase in the inequality of wealth results in an even sharper concentration of the liquid financial resources. This leads to a congestion of the flow of goods and the arrest of the economy when the Pareto exponent reaches one.

    The value of the time which people devote to each activity of their lives is compared with the money they spend on the activity. After tax wage rates are used to value an individual's time. The enormous size of the household economy and the fact that for most activities the value of the consumer's time devoted to an activity exceeds the money expenditures on the activity, suggest that there are many opportunities for productivity improvements in the household economy which have been overlooked in most traditional thinking on productivity.

  3. Some population and related problems in the Ghanaian Economy.

    1971-01-01

    A detailed review of the present situation of the Ghanaian economy indicates that, in spite of a decrease in the number of people employed in the agricultural sector (which might suggest an increase in agricultural productivity according to the thesis to this effect based on experiences in developed countries), food productivity has failed to improve. This is a serious situation for a population increasing at a rate of 2.7% per year. The large percentage of school-age children (21.8% with 44.5% of the population under 15 years as of 1960) necessitating education expenditures and the heavy immigration from surrounding countries (12% of the population are immigrants and they account for 50% of the male retail traders in the country according to the 1960 census) have created 2 of the largest problems for the country's economy. In 1960, 61.8% of the adult working population was employed in agriculture and agricultural products (primarily cocoa, which accounts for over 60% of this total) yet production lagged behind demand, making Ghana a net importer of food. Future prospects for Ghana's agricultural situation indicate that increase in production (estimated in 1965 at 1.62%) is far behind the estimated necessary increase of 7.7% based on food consumption levels of 1961. Even for cocoa production which had been progressing, the prospects are discouraging due to factors such as insufficient equipment, transportation facilities and other elements related to production maintenance, as well as to a shortage of labor (caused by the Aliens Compliance Order of 1969, the government's effort to reduce the involvement of immigrants in the economy) which has yet to be filled despite high urban unemployment rates and rural underemployment. Although producer prices for cocoa increased, little evidence can be found that this provided incentive for farmers to increase production. This review indicates that the country is still waiting for the agricultural revolution to arrive which

    Faced to the economic and energetic context of our society, it is widely recognised that an alternative to fossil fuels and oil-based products will be needed in the nearest future. In this way, development of urban biorefinery could bring many solutions to this problem. Study of the implementation of urban biorefinery highlights two sustainable configurations that provide solutions to the Walloon context by promoting niche markets, developing circular economy and reducing transport of supply feedstock. First, autonomous urban biorefineries are proposed, which use biological waste for the production of added value molecules and/or finished products and are energetically self-sufficient. Second, integrated urban biorefineries, which benefit from an energy supply from a nearby industrial activity. In the Walloon economic context, these types of urban biorefineries could provide solutions by promoting niche markets, developing a circular economy model, optimise the transport of supply feedstock and contribute to the sustainable development.

    Ahluwalia, R.; Wang, X.; Rousseau, A.; Nuclear Engineering Division

    2004-01-01

    The potential improvement in fuel economy of a mid-size fuel-cell vehicle by combining it with an energy storage system has been assessed. An energy management strategy is developed and used to operate the direct hydrogen, pressurized fuel-cell system in a load-following mode and the energy storage system in a charge-sustaining mode. The strategy places highest priority on maintaining the energy storage system in a state where it can supply unanticipated boost power when the fuel-cell system alone cannot meet the power demand. It is found that downsizing a fuel-cell system decreases its efficiency on a drive cycle which is compensated by partial regenerative capture of braking energy. On a highway cycle with limited braking energy the increase in fuel economy with hybridization is small but on the stop-and-go urban cycle the fuel economy can improve by 27%. On the combined highway and urban drive cycles the fuel economy of the fuel-cell vehicle is estimated to increase by up to 15% by hybridizing it with an energy storage system.

    PubMed

    Kanter, Rosabeth Moss

    2003-08-01

    More and more small and midsize companies are joining corporate giants in striving to exploit international growth markets. At the same time, civic leaders worry about their communities' economic future in light of the impact of global forces on the operation and survival of business. How can communities retain local vitality yet still link their business to the global economy? Harvard professor Rosabeth Moss Kanter addresses that question in this classic HBR article, orginally published in 1995. To avoid a clash between international economic interests and local political interests, globalizing business must learn how to be responsive to the communities in which they operate, Kanter says. And communities must determine how to create a civic culture that will attract and retain footloose companies. The author surveyed five U.S. regions with direct connections to the global economy--Boston, Cleveland, Miami, Seattle, and the Spartanburg-Greenville region of South Carolina--to determine their business and civic leader's strategies for improving their constituent's quality of life. She identified ways in which the global economy can work locally by capitalizing on the resources that distinguish one place from another. Kanter argues that regions can invest in capabilities that connect their local populations to the global economy in one of three ways: as thinkers, makers, or traders. She points to the Spartanburg-Greenville region as a good example of a world-class makers, with its exceptional blue-collar workforce that has attracted more than 200 companies from 18 countries. The history of the economic development of this region is a lesson for those seeking to understand how to achieve world-class status and bring local residents into the world economy. PMID:12884672

  1. Abraham Lincoln and the global economy.

    PubMed

    Hormats, Robert D

    2003-08-01

    Abraham Lincoln would have well understood the challenges facing many modern emerging nations. In Lincoln's America, as in many developing nations today, sweeping economic change threatened older industries, traditional ways of living, and social and national cohesion by exposing economies and societies to new and powerful competitive forces. Yet even in the midst of the brutal and expensive American Civil war--and in part because of it--Lincoln and the Republican Congress enacted bold legislation that helped create a huge national market, a strong and unified economy governed by national institutions, and a rising middle class of businessmen and property owners. Figuring out how to maximize the benefits of globalization while minimizing its disruptions is a formidable challenge for policy makers. How do you expand opportunities for the talented and the lucky while making sure the rest of society doesn't fall behind? It may be helpful to look at the principles that informed the policies that Lincoln and the Republican Congress instituted after they came to power in 1861: Facilitate the upward mobility of low- and middle-income groups to give them a significant stake in the country. Emphasize the good of the national economy over regional interests. Affirm the need for sound government institutions to temper the dynamics of the free enterprise system. Tailor policies to the national situation. Realize that a period of turmoil may present a unique opportunity for reform. These principles drove the reforms that helped Americans cope with and benefit from rapid technological advances and the fast integration of the American economy in the nineteenth century. They may be instructive to today's policy makers who are struggling to help their own citizens integrate into the fast-changing global economy of the twenty-first century. PMID:12884668

    2011-11-09

    A flow chart depicting energy flow in the transportation sector of the United States economy in 2005 has been constructed from publicly available data and estimates of national energy use patterns. Approximately 31,000 trillion British Thermal Units (trBTUs) of energy were used throughout the United States in transportation activities. Vehicles used in these activities include automobiles, motorcycles, trucks, buses, airplanes, rail, and ships. The transportation sector is powered primarily by petroleum-derived fuels (gasoline, diesel and jet fuel). Biomass-derived fuels, electricity and natural gas-derived fuels are also used. The flow patterns represent a comprehensive systems view of energy used within the transportation sector.

Two promising engine/transmission combinations, using gasoline, had 55 to 60 percent gains over the reference fuel economy. Fuel economy sensitivities to engine design parameter changes were also calculated for these two combinations.

    A discomforting reality has materialized on the transportation scene: our existing air and ground infrastructures will not scale to meet our nation's 21st century demands and expectations for mobility, commerce, safety, and security. The consequence of inaction is diminished quality of life and economic opportunity in the 21st century. Clearly, new thinking is required for transportation that can scale to meet to the realities of a networked, knowledge-based economy in which the value of time is a new coin of the realm. This paper proposes a framework, or topology, for thinking about the problem of scalability of the system of networks that comprise the aviation system. This framework highlights the role of integrated communication-navigation-surveillance systems in enabling scalability of future air transportation networks. Scalability, in this vein, is a goal of the recently formed Joint Planning and Development Office for the Next Generation Air Transportation System. New foundations for 21PstP thinking about air transportation are underpinned by several technological developments in the traditional aircraft disciplines as well as in communication, navigation, surveillance and information systems. Complexity science and modern network theory give rise to one of the technological developments of importance. Scale-free (i.e., scalable) networks represent a promising concept space for modeling airspace system architectures, and for assessing network performance in terms of scalability, efficiency, robustness, resilience, and other metrics. The paper offers an air transportation system topology as framework for transportation system innovation. Successful outcomes of innovation in air transportation could lay the foundations for new paradigms for aircraft and their operating capabilities, air transportation system architectures, and airspace architectures and procedural concepts.

  12. The token economy: an evaluative review1

    Kazdin, Alan E.; Bootzin, Richard R.

    1972-01-01

    Token economies have been applied in a wide range of settings. While there are several advantages to the use of this procedure, there are obstacles that may impede its implementation and therapeutic efficacy. These include: staff training, client resistance, circumvention of the contingencies, and non-responsiveness of subjects. Studies employing token programs with psychiatric patients, retardates, children in classroom settings, delinquents, and autistic children are reviewed. Although token economies are successful while in operation, the issue of generalization of behavior gains or resistance to extinction has not been given careful consideration. Inasmuch as generalization is perhaps the most crucial issue, several procedures are presented that are designed to facilitate maintenance of performance when reinforcement is withdrawn. Methodological suggestions for investigations on token reinforcement in applied settings are presented. PMID:16795358

    2011-12-01

    In this paper, environmental tax was designed to control volatile organic compounds (VOCs) emissions. Computable general equilibrium (CGE) model was used to explore the impacts of environmental tax (in forms of indirect tax) on the macro-economy development at both national and sector levels. Different levels of tax were simulated to find out the proper tax rate. It is found out that imposing environmental tax on high emission sectors can cause the emission decreased immediately and can lead to negative impacts on macro-economy indicators, such as GDP (gross domestic products), total investment, total product and the whole consumption etc. However, only the government income increased. In addition, the higher the tax rate is, the more pollutants can be reduced and the worse economic effects can be caused. Consequently, it is suggested that, the main controlling policies of VOCs abatement should be mandatory orders, and low environmental tax can be implemented as a supplementary. PMID:22468510

    2001-01-01

    Thailand has some of the world's strongest anti-tobacco legislation. This paper examines the political economy of tobacco control in Thailand, emphasising the identification of forces which have supported and opposed the passage of strong anti-tobacco measures. It argues that while a powerful tobacco control coalition was created in the late 1980s, the gains won by this coalition are now under threat from systematic attempts by transnational tobacco companies to strengthen their share of the Thai cigarette market. The possible privatisation of the Thailand Tobacco Monopoly could threaten the tobacco control cause, but the pro-control alliance is fighting back with a proposed Health Promotion Act which would challenge the tobacco industry with a hypothecated excise tax dedicated to health awareness campaigns.

    On average, brain network economy represents a trade-off between communication efficiency, robustness and connection cost, though, an analogous understanding on an individual level is largely missing. Evaluating resting-state networks of 42 healthy participants with 7 Tesla functional MRI and graph theory revealed that not even half of all possible connections were common across subjects. The strongest similarities among individuals were observed for interhemispheric and/or short-range connections, which may relate to the essential feature of the human brain to develop specialized systems within each hemisphere. Despite this marked variability in individual network architecture, all subjects exhibited equal small-world properties. Furthermore, interdependency between four major network economy metrics was observed across healthy individuals. The characteristic path length was associated with the clustering coefficient (peak correlation r=0.93), the response to network attacks (r=−0.97) and the physical connection cost in 3D space (r=−0.62). On the other hand, clustering was negatively related to attack response (r=−0.75) and connection cost (r=-0.59). Finally, increased connection cost was associated with better response to attacks (r=0.65). This indicates that functional brain networks with high global information transfer also exhibit strong network resilience. However, it seems that these advantages come at the cost of decreased local communication efficiency and increased physical connection cost. Except for wiring length, the results were replicated on a subsample at 3 Tesla (n=20). These findings highlight the finely tuned interrelationships between different parameters of brain network economy. Moreover, the understanding of the individual diversity of functional brain network economy may provide further insights in the vulnerability to mental and neurological disorders. PMID:25411715

  17. Influence of the formation- and passivation rate of boron-oxygen defects for mitigating carrier-induced degradation in silicon within a hydrogen-based model

    Hallam, Brett; Abbott, Malcolm; Nampalli, Nitin; Hamer, Phill; Wenham, Stuart

    2016-02-01

    A three-state model is used to explore the influence of defect formation- and passivation rates of carrier-induced degradation related to boron-oxygen complexes in boron-doped p-type silicon solar cells within a hydrogen-based model. The model highlights that the inability to effectively mitigate carrier-induced degradation at elevated temperatures in previous studies is due to the limited availability of defects for hydrogen passivation, rather than being limited by the defect passivation rate. An acceleration of the defect formation rate is also observed to increase both the effectiveness and speed of carrier-induced degradation mitigation, whereas increases in the passivation rate do not lead to a substantial acceleration of the hydrogen passivation process. For high-throughput mitigation of such carrier-induced degradation on finished solar cell devices, two key factors were found to be required, high-injection conditions (such as by using high intensity illumination) to enable an acceleration of defect formation whilst simultaneously enabling a rapid passivation of the formed defects, and a high temperature to accelerate both defect formation and defect passivation whilst still ensuring an effective mitigation of carrier-induced degradation.

  18. Factors Affecting Informal Economy of Rural Turkey

    NASA Astrophysics Data System (ADS)

    Gonenc, Sertac; Tanrivermis, Harun

    In this study, the informal economy in the rural areas of Turkey has been measured and factors affecting the informal economy have been analyzed. The informal economy has been discussed with regards to three main issues, namely unpaid household labor force usage, own consumption of crop and animal products and informal sales. Although the household labor force is mainly used in farms for agricultural and off-farm activities, the rate of idle labor has been found to be highly significant. It has been found that milk has the largest share of animal produce values consumed by the household, while particularly processed milk products are sold informally and that the consumption and sales values of animal produce processed in the households are required to be added to the unrecorded value calculation. Consumption of crops varies depending on the type of product. The own consumption ratio of crops is affected by the size of the enterprise, the number of individuals in the households and particularly the access to the markets of the enterprises in each region. An average informal value of 6,400.04 USD has been calculated per household, which is higher than the farm income, accounting for 4/5 of total household income. This can be attributed to the fact that the farms are generally small family enterprises with limited market-access opportunities.

    2003-01-01

    Health impact assessment (HIA) can be used to examine the relationships between inequalities and health. This HIA of Edinburgh's transport policy demonstrates how HIA can examine how different transport policies can affect different population groupings to varying degrees. In this case, Edinburgh's economy is based on tourism, financial services and Government bodies. These need a good transport infrastructure, which maintains a vibrant city centre. A transport policy that promotes walking, cycling and public transport supports this and is also good for health. The HIA suggested that greater spend on public transport and supporting sustainable modes of transport was beneficial to health, and offered scope to reduce inequalities. This message was understood by the City Council and influenced the development of the city's transport and land-use strategies. The paper discusses how HIA can influence public policy. PMID:12802900

    The public, automakers, and policymakers have long worried about trade-offs between increased fuel economy in motor vehicles and reduced safety. The conclusion of a broad group of experts on safety and fuel economy in the auto sector is that no trade-off is required. There are a wide variety of technologies and approaches available to advance vehicle fuel economy that have no effect on vehicle safety. Conversely, there are many technologies and approaches available to advance vehicle safety that are not detrimental to vehicle fuel economy. Congress is considering new policies to increase the fuel economy of new automobiles in order to reduce oil dependence and reduce greenhouse gas emissions. The findings reported here offer reassurance on an important dimension of that work: It is possible to significantly increase the fuel economy of motor vehicles without compromising their safety. Automobiles on the road today demonstrate that higher fuel economy and greater safety can co-exist. Some of the safest vehicles have higher fuel economy, while some of the least safe vehicles driven today--heavy, large trucks and SUVs--have the lowest fuel economy. At an October 3, 2006 workshop, leading researchers from national laboratories, academia, auto manufacturers, insurance research industry, consumer and environmental groups, material supply industries, and the federal government agreed that vehicles could be designed to simultaneously improve safety and fuel economy. The real question is not whether we can realize this goal, but the best path to get there. The experts' studies reveal important new conclusions about fuel economy and safety, including: (1) Vehicle fuel economy can be increased without affecting safety, and vice versa; (2) Reducing the weight and height of the heaviest SUVs and pickup trucks will simultaneously increase both their fuel economy and overall safety; and (3) Advanced materials can decouple size from mass, creating important new possibilities for

    2004-08-31

    The announcement of a hydrogen fuel initiative in the President’s 2003 State of the Union speech substantially increased interest in the potential for hydrogen to play a major role in the nation’s long-term energy future. Prior to that event, DOE asked the National Research Council to examine key technical issues about the hydrogen economy to assist in the development of its hydrogen R&D program. Included in the assessment were the current state of technology; future cost estimates; CO2 emissions; distribution, storage, and end use considerations; and the DOE RD&D program. The report provides an assessment of hydrogen as a fuel in the nation’s future energy economy and describes a number of important challenges that must be overcome if it is to make a major energy contribution. Topics covered include the hydrogen end-use technologies, transportation, hydrogen production technologies, and transition issues for hydrogen in vehicles.

    This report presents, Aspen. Sandia National Laboratories is developing this new agent-based microeconomic simulation model of the U.S. economy. The model is notable because it allows a large number of individual economic agents to be modeled at a high level of detail and with a great degree of freedom. Some features of Aspen are (a) a sophisticated message-passing system that allows individual pairs of agents to communicate, (b) the use of genetic algorithms to simulate the learning of certain agents, and (c) a detailed financial sector that includes a banking system and a bond market. Results from runs of the model are also presented.

    The objectives and assumptions of health care reform have changed repeatedly during the past century and may now be entering a new historical phase as a result of the "new economy" rooted in information technology. In a high-growth context, proponents of reform may no longer feel obliged to bundle expanded coverage with tighter cost containment. At the same time, the new digital environment may facilitate innovations intended to inform and expand consumer choice and to improve quality. The new environment elevates "transparency" to a guiding principle. Health informatics has long been peripheral to reform and must now become more central. PMID:11192407

    MM II defined a series of experiments to better understand and characterize model transport and to assess the realism of this transport by comparison to observations. Measurements from aircraft, balloon, and satellite, not yet available at the time of MM I [Prather and Remsberg, 1993], provide new and stringent constraints on model transport, and address the limits of our transport modeling abilities. Simulations of the idealized tracers the age spectrum, and propagating boundary conditions, and conserved HSCT-like emissions probe the relative roles of different model transport mechanisms, while simulations of SF6 and C02 make the connection to observations. Some of the tracers are related, and transport diagnostics such as the mean age can be derived from more than one of the experiments for comparison to observations. The goals of the transport experiments are: (1) To isolate the effects of transport in models from other processes; (2) To assess model transport for realistic tracers (such as SF6 and C02) for comparison to observations; (3) To use certain idealized tracers to isolate model mechanisms and relationships to atmospheric chemical perturbations; (4) To identify strengths and weaknesses of the treatment of transport processes in the models; (5) To relate evaluated shortcomings to aspects of model formulation. The following section are included:Executive Summary, Introduction, Age Spectrum, Observation, Tropical Transport in Models, Global Mean Age in Models, Source-Transport Covariance, HSCT "ANOY" Tracer Distributions, and Summary and Conclusions.

  12. Agrofuels capitalism: a view from political economy.

    PubMed

    White, Ben; Dasgupta, Anirban

    2010-01-01

    This article considers the global expansion of agrofuels feedstock production from a political economy perspective. It considers and dismisses the environmental and pro-poor developmental justifications attached to agrofuels. To local populations and direct producers, the specific destination of the crop as fuel, food, cosmetics or other final uses in faraway places is probably of less interest than the forms of (direct or indirect) appropriation of their land and the forms of their insertion or exclusion as producers in global commodity chains. Global demand for both agrofuels and food is stimulating new forms (or the resurgence of old forms) of corporate land grabbing and expropriation, and of incorporation of smallholders in contracted production. Drawing both on recent studies on agrofuels expansion and on the political economy literature on agrarian transition and capitalism in agriculture, this article raises the question whether "agrofuels capitalism" is in any way essentially different from other forms of capitalist agrarian monocrop production, and in turn whether the agrarian transitions involved require new tools of analysis.

    The Rio+20 Conference will mobilize the global community in 2012 to participate in a challenging debate on the global environmental reality and the existing modus operandi with respect to the broad and generic topics of development and the environment. One of the core themes of this meeting is the transition to a green economy in the context of sustainable development and the eradication of poverty. The issue of Global Environmental Governance will top the agenda of the Rio +20 discussions, with a view to promoting and accelerating the transition to sustainable societies. It presents, often in a controversial way, the creation of conditions to define new institutional spaces and shared decision-making processes. Before embarking on the discussion about what king of sustainability should be behind the Green Economy, and its applicability, the scope of this article is to ask readers to reflect on what should be the priority in the discussion on environmental governance This should be explained to the extent that there is a need to change the existing mechanisms of profoundly unequal exploitation of resources, which blocks progress in decision-making processes, as decisions of the few create a perverse logic of appropriation of natural resources and the non-resolution of social exclusion.

  14. Transportation energy trends and issues through 2030

    DeCicco, J.M.

    1996-12-31

    Controlling transportation energy use looms as a serious challenge for the United States in the 21st century. Demand for transportation services is steadily growing, driven by increasing population, economic activity, and incomes. Few forces presently constrain growth in travel by the energy-intensive modes of automobile, truck, and air transportation. In contrast to other sectors of the economy, transportation energy efficiency improvements are nearly stagnant. Efficiency increases are now absent in highway modes; aircraft efficiency is improving, but not enough to offset rising air travel. Transportation is also the most oil-dependent sector of the economy as well as the country`s most rapidly growing source of greenhouse gas emissions. A conservative forecast indicates US transportation energy consumption rising from 23 Quads in 1990 to roughly 36 Quads by 2030; less conservative assumptions push the total to 43 Quads by 2030. Yet opportunities exist for efficiency improvements to counter a substantial portion of this growth. The most promising options are technological, with potential long-term efficiency improvements of threefold for light vehicles, twofold for aircraft, and 65 percent for heavy trucks. Combined with system efficiency changes to help limit growth of the energy-intensive modes, transportation energy use might be cut to 19 Quads by 2030. Pursuing cost-effective strategies to move the system toward such reduced energy intensiveness would be clearly valuable for the economy and environment. This paper examines these trends and options, and offers suggestions for policies that could lead to reductions in transportation energy use and its associated problems such as greenhouse gas emissions and oil dependence risks. 24 refs., 6 figs., 3 tabs.

  15. The water intensity of the plugged-in automotive economy.

    King, Carey W; Webber, Michael E

    2008-06-15

    Converting light-duty vehicles from full gasoline power to electric power, by using either hybrid electric vehicles or fully electric power vehicles, is likely to increase demand for water resources. In the United States in 2005, drivers of 234 million cars, lighttrucks, and SUVs drove approximately 2.7 trillion miles and consumed over 380 million gallons of gasoline per day. We compare figures from literature and government surveys to calculate the water usage, consumption, and withdrawal, in the United States during petroleum refining and electricity generation. In displacing gasoline miles with electric miles, approximately 2-3 [corrected] times more water is consumed (0.24 [corrected] versus 0.07--0.14 gallons/mile) and over 12 [corrected] times more water is withdrawn (7.8 [corrected] versus 0.6 gallons/mile) primarily due to increased water cooling of thermoelectric power plants to accommodate increased electricity generation. Overall, we conclude that the impact on water resources from a widespread shift to grid-based transportation would be substantial enough to warrant consideration for relevant public policy decision-making. That is not to say that the negative impacts on water resources make such a shift undesirable, but rather this increase in water usage presents a significant potential impact on regional water resources and should be considered when planning for a plugged-in automotive economy.

    We extend the theoretical framework of an independent economy developed by Tao [Phys. Rev. E 82 (2010) 036118] so as to include multiple economies. Since the starting point of our framework is on the basis of the theory of the competitive markets of traditional economics, this framework shall be suitable for any free market. Our study shows that integration of world economies can decrease trade friction among economic systems, but may also cause a global economic crisis whenever economy disequilibrium occurs in any one of these economic systems.

    Williams, Christine L.; Muller, Chandra; Kilanski, Kristine

    2014-01-01

    Gender scholars draw on the “theory of gendered organizations” to explain persistent gender inequality in the workplace. This theory argues that gender inequality is built into work organizations in which jobs are characterized by long-term security, standardized career ladders and job descriptions, and management controlled evaluations. Over the past few decades, this basic organizational logic has been transformed. in the so-called new economy, work is increasingly characterized by job insecurity, teamwork, career maps, and networking. Using a case study of geoscientists in the oil and gas industry, we apply a gender lens to this evolving organization of work. This article extends Acker's theory of gendered organizations by identifying the mechanisms that reproduce gender inequality in the twenty-first-century workplace, and by suggesting appropriate policy approaches to remedy these disparities.

  20. Scale economies in rail transit systems

    SciTech Connect

    Savage, I.

    1994-06-01

    The research uses Federal Transit Administration Section 15 data to investigate the operating costs of 13 heavy-rail and 13 light-rail urban mass transit systems for the period 1985-91. A Cobb-Douglas technology is used to investigate various types of economies of scale. The principal findings are: (1) Adding additional passenges to an existing network and schedule of services involves zero marginal cost for heavy-rail systems, and small additional costs for light-rail systems. (2) Adding additional trains, and passengers, to an existing network leads to a less than proportionate increase in costs. (3) An expanded route network results in mild increases in unit costs for the large heavy-rail systems. The smaller light-rail systems display reduced unit costs with an expanded network. The research suggests that the minimum efficient scale for rail operation is approximately 25 route miles.

  1. Environmental policy in economies in transition.

    PubMed

    Zylicz, T

    1999-01-01

    Considerable improvement in environmental pollution has been achieved, primarily due to targeted environmental policies rather than general economic developments. Some countries in central and eastern Europe have managed to reduce emissions even after the gross domestic product once again began to increase. Everywhere in the region, however, the cost-effectiveness of environmental spending is questionable. Most countries have established systems of earmarked resource and pollution taxes, which provide a sizable share in financing environmental investment. With stationary sources of pollution brought under increasingly effective control, the environmental problems in central and eastern Europe, and eventually in the newly independent states, will start to resemble those of developed market economies. As more activities become affected by environmental protection measures, cost-effectiveness considerations deserve increased attention. PMID:10546809

    The method developed for initial evaluation of possible performance improvements in the NASA Aircraft Energy Efficiency Program, directed toward improving the fuel economy of turbofan engines, is outlined, and results of the evaluation of 100 candidate engine modifications are presented. The study indicates that fuel consumption improvements of as much as 5% may be possible in current JT3D, JT8D, and JT9D turbofan engines. Aerodynamic, thermodynamic, material, and structural advances are expected to yield fuel consumption improvements on the order of 10 to 15% in advanced turbofan engines, with the greatest improvement stemming from significantly higher cycle pressure ratios. Higher turbine temperature and fan bypass ratios are also expected to contribute to fuel conservation.

    2011-12-01

    With some of the lowest development indicators in Southeast Asia, remote upland areas of the Lao People's Democratic Republic are among the poorest in the region. The advent of improved transport and communication links, along with opportunities for wage employment, have accelerated the growth of a cash economy in traditionally isolated farming communities of Luang Namtha Province. Interviews and focus group discussions with young people, women in the sexual service business and health workers indicate that the lure of the new economy is wooing villagers away from their agrarian roots. Motorbikes and mobile phones have expanded the sexual territory of indigenous youth at a time when international commerce and a cash economy along improved highways are bringing new people into the region. Among the concerns for their health and safety are at-risk behaviours involving alcohol and sexual practices, especially HIV and sexually transmitted infections. Of particular concern is the sexual trade in the province with a predominance of young, poorly educated Khmou women providing sexual services in a growing number of entertainment places.

    The reduction of transport-generated CO2 emissions is currently a problem of global interest. Hybrid electric vehicles (HEVs) are considered as one promising technological solution for limiting transport-generated greenhouse gas emissions. Currently, the number of HEVs in the market remains limited, but this picture will change in the years to come as HEVs are expected to pave the way for cleaner technologies in transport. In this paper, results are presented regarding fuel economy and pollutant emissions measurements of two hybrid electric production vehicles. The measurements were conducted on a Prius II and a Honda Civic IMA using both the European legislated driving cycle (New European Driving Cycle, NEDC) and real-world simulation driving cycles (Artemis). In addition to the emissions measurements, other vehicle-operating parameters were studied in an effort to better quantify the maximum CO2 reduction potential. Data from real-world operation of a Prius II vehicle were also used in the evaluation. Results indicate that in most cases both vehicles present improved energy efficiency and pollutant emissions compared to conventional cars. The fuel economy benefit of the two HEVs peaked under urban driving conditions where reductions of 60% and 40% were observed, respectively. Over higher speeds the difference in fuel economy was lower, reaching that of conventional diesel at 95 km h-1. The effect of ambient temperature on fuel consumption was also quantified. It is concluded that urban operation benefits the most of hybrid technology, leading to important fuel savings and urban air quality improvement.

    The U.S. Department of Energy report, Effects of a Transition to a Hydrogen Economy on Employment in the United States Report to Congress, estimates the effects on employment of a U.S. economy transformation to hydrogen between 2020 and 2050. The report includes study results on employment impacts from hydrogen market expansion in the transportation, stationary, and portable power sectors and highlights possible skill and education needs. This study is in response to Section 1820 of the Energy Policy Act of 2005 (Public Law 109-58) (EPACT). Section 1820, “Overall Employment in a Hydrogen Economy,” requires the Secretary of Energy to carry out a study of the effects of a transition to a hydrogen economy on several employment [types] in the United States. As required by Section 1820, the present report considers: • Replacement effects of new goods and services • International competition • Workforce training requirements • Multiple possible fuel cycles, including usage of raw materials • Rates of market penetration of technologies • Regional variations based on geography • Specific recommendations of the study Both the Administration’s National Energy Policy and the Department’s Strategic Plan call for reducing U.S. reliance on imported oil and reducing greenhouse gas emissions. The National Energy Policy also acknowledges the need to increase energy supplies and use more energy-efficient technologies and practices. President Bush proposed in his January 2003 State of the Union Address to advance research on hydrogen so that it has the potential to play a major role in America’s future energy system. Consistent with these aims, EPACT 2005 authorizes a research, development, and demonstration program for hydrogen and fuel cell technology.

    All states are strongly committed to economic development policies and activities as participants in national and global competition. However, a sometimes overlooked and perhaps under appreciated influence on economic development is the health of a state's citizens. This study focuses on how the health status of Kentucky profoundly influences its economy, workforce, productivity, and general quality of life. If Kentucky's economy is to improve significantly, as compared to other states, significant improvements in the health status of its citizens must be achieved in the near future and sustained over time. In an era of growing concern about rising health insurance costs and maintaining a reliable and productive workforce, employers are increasingly likely to locate in communities where measures of health status are strongly positive. The latest report from the United Health Foundation indicates that in 2007 Kentucky had the 8th worst health status in the nation based on a set of risk factors and outcomes. These risk factors include personal behaviors, community and environment, and public health policies that culminate in key health outcomes related to quality of life and longevity. While it is a serious challenge, our research demonstrates that many of these risk factors can be lowered through relatively low cost and effective interventions that produce substantial improvements in health and Kentucky's rank. Health education is very effective when it begins early in life and continues to emphasize the importance of healthy behaviors, such as not smoking, healthy diets and exercise, and weight control. Preventive health services that identify and treat diseases and conditions that lead to premature death increase both longevity and economic growth through lower treatment costs for chronic diseases and an increase in human capital.

    1. In mammals, nucleoside transport is an important determinant of the pharmacokinetics, plasma and tissue concentration, disposition and in vivo biological activity of adenosine as well as nucleoside analogues used in antiviral and anticancer therapies. 2. Two broad types of adenosine transporter exist, facilitated-diffusion carriers and active processes driven by the transmembrane sodium gradient. 3. Facilitated-diffusion adenosine carriers may be sensitive (es) or insensitive (ei) to nanomolar concentrations of the transport inhibitor nitrobenzylthioinosine (NBMPR). Dipyridamole, dilazep and lidoflazine analogues are also more potent inhibitors of the es carrier than the ei transporter in cells other than those derived from rat tissues. 4. The es transporter has a broad substrate specificity (apparent Km for adenosine approximately 25 microM in many cells at 25 degrees C), is a glycoprotein with an average apparent Mr of 57,000 in human erythrocytes that has been purified to near homogeneity and may exist in situ as a dimer. However, there is increasing evidence to suggest the presence of isoforms of the es transporter in different cells and species, based on kinetic and molecular properties. 5. The ei transporter also has a broad substrate specificity with a lower affinity for some nucleoside permeants than the es carrier, is genetically distinct from es but little information exists as to the molecular properties of the protein. 6. Sodium-dependent adenosine transport is present in many cell types and catalysed by four distinct systems, N1-N4, distinguished by substrate specificity, sodium coupling and tissue distribution. 7. Two genes have been identified which encode sodium-dependent adenosine transport proteins, SNST1 from the sodium/glucose cotransporter (SGLT1) gene family and the rat intestinal N2 transporter (cNT1) from a novel gene family including a bacterial nucleoside carrier (NupC). Transcripts of cNT1, which encodes a 648-residue protein, are

    As intercontinental business and tourism volumes continue their rapid expansion, the need to reduce travel times becomes increasingly acute. The Edge Supersonic Transport Aircraft is designed to meet this demand by the year 2015. With a maximum range of 5750 nm, a payload of 294 passengers and a cruising speed of M = 2.4, The Edge will cut current international flight durations in half, while maintaining competitive first class, business class, and economy class comfort levels. Moreover, this transport will render a minimal impact upon the environment, and will meet all Federal Aviation Administration Part 36, Stage III noise requirements. The cornerstone of The Edge's superior flight performance is its aerodynamically efficient, dual-configuration design incorporating variable-geometry wingtips. This arrangement combines the benefits of a high aspect ratio wing at takeoff and low cruising speeds with the high performance of an arrow-wing in supersonic cruise. And while the structural weight concerns relating to swinging wingtips are substantial, The Edge looks to ever-advancing material technologies to further increase its viability. Heeding well the lessons of the past, The Edge design holds economic feasibility as its primary focus. Therefore, in addition to its inherently superior aerodynamic performance, The Edge uses a lightweight, largely windowless configuration, relying on a synthetic vision system for outside viewing by both pilot and passengers. Additionally, a fly-by-light flight control system is incorporated to address aircraft supersonic cruise instability. The Edge will be produced at an estimated volume of 400 aircraft and will be offered to airlines in 2015 at $167 million per transport (1992 dollars).

  9. Economies of density for on-site waste water treatment.

    2016-09-15

    Decentralised wastewater treatment is increasingly gaining interest as a means of responding to sustainability challenges. Cost comparisons are a crucial element of any sustainability assessment. While the cost characteristics of centralised waste water management systems (WMS) have been studied extensively, the economics of decentralised WMS are less understood. A key motivation for studying the costs of decentralised WMS is to compare the cost of centralised and decentralised WMS in order to decide on cost-efficient sanitation solutions. This paper outlines a model designed to assess those costs which depend on the spatial density of decentralised wastewater treatment plants in a region. Density-related costs are mostly linked to operation and maintenance activities which depend on transportation, like sludge removal or the visits of professionals to the plants for control, servicing or repairs. We first specify a modelled cost-density relationship for a region in a geometric two-dimensional space by means of heuristic routing algorithms that consider time and load-capacity restrictions. The generic model is then applied to a Swiss case study for which we specify a broad range of modelling parameters. As a result, we identify a 'hockey-stick'-shaped cost curve that is characterised by strong cost reductions at high density values which level out at around 1 to 1.5 plants per km(2). Variations in the cost curves are mostly due to differences in management approaches (scheduled or unscheduled emptying). In addition to the well-known diseconomies of scale in the case of centralised sanitation, we find a similar generic cost behaviour for decentralised sanitation due to economies of density. Low densities in sparsely populated regions thus result in higher costs for both centralised and decentralised system. Policy implications are that efforts to introduce decentralised options in a region should consider the low-density/high-cost problem when comparing centralised

    The continuous growth in global energy consumption has created international concern about the linkage between energy and socioeconomic development. Provoked by awareness of the potential effects of long-term growth in energy use on fuel availability, economics, geopolitics, and environmental quality, considerable scholarly attention has focused on assessing historical patterns as well as generating plausible estimates of alternative energy futures. While conservation projections to the middle of the next century suggest the existing developed countries will then be using about one-half of the world's energy with the US share declining to roughly one-sixth of the world's total, overall consumption is likely to increase due to population growth as well as economic modernization among the current set of developing countries. Not surprisingly, scenarios such as this raise the question of the social, political, and economic implications of varying energy supply systems. This book seeks to provide answers to that question by presenting a broad, historical analysis of the role played by changing energy management systems in the international political economy of this century. In the study, the author primarily concentrates on attempting to identify institutional factors and salient events shaping the politics and economics of global energy supply and utilization patterns from approximately 1900 to 1980. While the primary emphasis is on the Western industrialized countries and the less-developed countries (LDCs) which are energy-producing states, some attention also is devoted to the Soviet Union, Eastern Europe, and the energy-importing LDCs.

    Due to its phenomenal growth requiring neither nitrogen fertilizer nor arable land and its biomass composition, the mosquito fern Azolla is a candidate crop to yield food, fuels and chemicals sustainably. To advance Azolla domestication, we research its dissemination, storage and transcriptome. Methods for dissemination, cross-fertilization and cryopreservation of the symbiosis Azolla filiculoides-Nostoc azollae are tested based on the fern spores. To study molecular processes in Azolla including spore induction, a database of 37 649 unigenes from RNAseq of microsporocarps, megasporocarps and sporophytes was assembled, then validated. Spores obtained year-round germinated in vitro within 26 d. In vitro fertilization rates reached 25%. Cryopreservation permitted storage for at least 7 months. The unigene database entirely covered central metabolism and to a large degree covered cellular processes and regulatory networks. Analysis of genes engaged in transition to sexual reproduction revealed a FLOWERING LOCUS T-like protein in ferns with special features induced in sporulating Azolla fronds. Although domestication of a fern-cyanobacteria symbiosis may seem a daunting task, we conclude that the time is ripe and that results generated will serve to more widely access biochemicals in fern biomass for a biobased economy.

    We present a stochastic agent-based model for the distribution of personal incomes in a developing economy. We start with the assumption that incomes are determined both by individual labour and by stochastic effects of trading and investment. The income from personal effort alone is distributed about a mean, while the income from trade, which may be positive or negative, is proportional to the trader's income. These assumptions lead to a Langevin model with multiplicative noise, from which we derive a Fokker-Planck (FP) equation for the income probability density function (IPDF) and its variation in time. We find that high earners have a power law income distribution while the low-income groups have a Levy IPDF. Comparing our analysis with the Indian survey data (obtained from the world bank website: http://go.worldbank.org/SWGZB45DN0) taken over many years we obtain a near-perfect data collapse onto our model's equilibrium IPDF. Using survey data to relate the IPDF to actual food consumption we define a poverty index (Sen A. K., Econometrica., 44 (1976) 219; Kakwani N. C., Econometrica, 48 (1980) 437), which is consistent with traditional indices, but independent of an arbitrarily chosen "poverty line" and therefore less susceptible to manipulation.

  13. Laos: rural economy threatened by AIDS.

    Laos is a rural country in which more than 70% of the work force depends upon the agricultural sector for its livelihood. Crop production in Laos is a low-productivity, labor-intensive affair which is highly vulnerable to disruption by natural disasters and outbreaks of disease. Laos is also a crossroads for trade from Cambodia, China, Thailand, and Vietnam. While such trade has some positive effect upon the domestic economy, it also facilitates the spread of sexually transmitted diseases into Laos from neighboring countries with high rates of HIV infection. The northwestern trading corridor bordering Thailand, Myanmar, and China is of particular concern with regard to the spread of HIV. The Lao government identified eleven individuals infected with HIV and had officially reported only one case of AIDS to the World Health Organization (WHO) as of April 1992. Although WHO has not yet confirmed or projected the number of HIV-seropositive and AIDS cases in Laos, scant available data suggest that AIDS is concentrated in urban areas. Poverty and isolation will not, however, protect rural villages from HIV. The implications of a growing HIV/AIDS epidemic for rural social structures are considered. It is clear that such a situation could lead to agroeconomic dislocation and jeopardize national food security. The following measures are recommended to confront HIV/AIDS in the agricultural sector: change cropping systems, provide AIDS prevention education and technical assistance, and recruit village cadres to increase AIDS awareness among young Lao and care for the very ill.

    Unlike the traditional factors of production--land, labor, and capital--knowledge is a resource that can't be forced out of people. But creating and sharing knowledge is essential to fostering innovation, the key challenge of the knowledge-based economy. To create a climate in which employees volunteer their creativity and expertise, managers need to look beyond the traditional tools at their disposal. They need to build trust. The authors have studied the links between trust, idea sharing, and corporate performance for more than a decade. They have explored the question of why managers of local subsidiaries so often fail to share information with executives at headquarters. They have studied the dynamics of idea sharing in product development teams, joint ventures, supplier partnerships, and corporate transformations. They offer an explanation for why people resist change even when it would benefit them directly. In every case, the decisive factor was what the authors call fair process--fairness in the way a company makes and executes decisions. The elements of fair process are simple: Engage people's input in decisions that directly affect them. Explain why decisions are made the way they are. Make clear what will be expected of employees after the changes are made. Fair process may sound like a soft issue, but it is crucial to building trust and unlocking ideas. Without it, people are apt to withhold their full cooperation and their creativity. The results are costly: ideas that never see daylight and initiatives that are never seized. PMID:10168337

    PNNL and the Volpentest Hazardous Materials Management and Emergency Response (HAMMER) Training and Education Center are helping to prepare emergency responders and permitting/code enforcement officials for their respective roles in the future Hydrogen Economy. Safety will be a critical component of the anticipated hydrogen transition. Public confidence goes hand in hand with perceived safety to such an extent that, without it, the envisioned transition is unlikely to occur. Stakeholders and the public must be reassured that hydrogen, although very different from gasoline and other conventional fuels, is no more dangerous. Ensuring safety in the hydrogen infrastructure will require a suitably trained emergency response force for containing the inevitable incidents as they occur, coupled with knowledgeable code officials to ensure that such incidents are kept to a minimum. PNNL and HAMMER are, therefore, designing a hydrogen safety training program, funded by DOE's Hydrogen, Fuel Cells, and Infrastructure Technologies Program, and modeled after the Occupational Safety and Health Administration’s multi-tiered approach to hazardous materials training. Capabilities under development at HAMMER include classroom and long-distance (i.e., satellite and internet broadcast) learning, as well as life-size, hands-on hydrogen burn props for “training as real as it gets.” This paper presents insights gained from the early emergency response hydrogen safety training courses held in 2005 and current plans for design and construction of a number of hydrogen burn props.

    We explore here the evolution of skiing locomotion in the last few thousand years by investigating how humans adapted to move effectively in lands where a cover of snow, for several months every year, prevented them from travelling as on dry ground. Following historical research, we identified the sets of skis corresponding to the ‘milestones’ of skiing evolution in terms of ingenuity and technology, built replicas of them and measured the metabolic energy associated to their use in a climate-controlled ski tunnel. Six sets of skis were tested, covering a span from 542 AD to date. Our results show that: (i) the history of skiing is associated with a progressive decrease in the metabolic cost of transport, (ii) it is possible today to travel at twice the speed of ancient times using the same amount of metabolic power and (iii) the cost of transport is speed-independent for each ski model, as during running. By combining this finding with the relationship between time of exhaustion and the sustainable fraction of metabolic power, a prediction of the maximum skiing speed according to the distance travelled is provided for all past epochs, including two legendary historical journeys (1206 and 1520 AD) on snow. Our research shows that the performances in races originating from them (Birkebeiner and Vasaloppet) and those of other modern competitions (skating versus classical techniques) are well predicted by the evolution of skiing economy. Mechanical determinants of the measured progression in economy are also discussed in the paper. PMID:16048771

    An economy whose activity is to be predicted comprises a plurality of decision makers. Decision makers include, for example, households, government, industry, and banks. The decision makers are represented by agents, where an agent can represent one or more decision makers. Each agent has decision rules that determine the agent's actions. Each agent can affect the economy by affecting variable conditions characteristic of the economy or the internal state of other agents. Agents can communicate actions through messages. On a multiprocessor computer, the agents can be assigned to processing elements.

    Abeberese, Ama Baafra

    The performance of firms is central to growth in developing economies. A burgeoning literature within development economics seeks to understand the behavior of firms in developing countries and the constraints to their performance. This dissertation explores two types of constraints---infrastructure-related constraints and trade-related constraints---faced by manufacturing firms in developing countries. Despite the widely acknowledged importance of infrastructure for economic growth, there has been relatively little research on how infrastructure affects the decisions of firms. Electricity, in particular, is commonly cited by firms in developing countries as a major obstacle to their performance. In the first two chapters, I analyze the responses of firms to two types of electricity constraints, namely electricity prices and electricity shortages. Chapter 1 provides evidence on how electricity prices affect a firm's industry choice and productivity growth using data on Indian manufacturing firms. I construct an instrument for electricity price as the interaction between the price of coal paid by power utilities, which is arguably exogenous to firm characteristics, and the initial share of thermal generation in a state's total electricity generation capacity. I find that, in response to an exogenous increase in electricity price, firms reduce their electricity consumption and switch to industries with less electricity-intensive production processes. I also find that firm output, machine intensity and labor productivity decline with an increase in electricity price. In addition to these level effects, I show that firm output and productivity growth rates are negatively affected by high electricity prices. These results suggest that electricity constraints faced by firms may limit a country's growth by leading firms to operate in industries with fewer productivity-enhancing opportunities. Chapter 2 examines the impact of electricity shortages on firm investment. I

    electrolysis, from coal, and directly from thermal energy could be found that are less expensive than those now available; inexpensive fuel cells could be developed, and high-temperature turbines could be used for the efficient conversion of hydrogen (and oxygen) to electricity. The use of hydrogen as an automotive fuel would be a key factor in the development of a hydrogen energy economy, and safe storage techniques for carrying sufficient quantities of hydrogen in automotive systems can certainly be developed. The use of hydrogen in automobiles would significantly reduce urban pollution because the dispersed fossil fuel emissions would be replaced by radioactive wastes generated at large central stations. The conversion of internal or external combustion engines for combustion of hydrogen fuel would probably have less economic impact on the automotive industry than the mass introduction of electric automobiles. However, this is a subject that requires more detailed study. All of the safety aspects of hydrogen utilization will have to be examined, especially the problems of safety in the domestic use and the long distance transport of hydrogen in pipelines at high pressures. It is our opinion that the various energy planning agencies should now begin to outline the mode of implementing hydrogen energy delivery systems in the energy economy. The initial transition to hydrogen energy derived from available fossil fuels such as coal should be considered together with the long range view of all the hydrogen being derived eventually from nuclear energy. By the year 1985 when petroleum imports may be in excess of the domestic supply, these plans could set the stage for the transition period from fossil to a predominantly nuclear energy economy able to supply abundant synthetic fuels such as hydrogen. Synthetic fuels will obviously be more expensive than fuels now derived from petroleum; however, there may be no other viable choice. Thus, it is essential that the analysis and

    An intriguing aspect of cardiac mechanoenergetics is the smaller variability of the contractile efficiency than the energy economy of force. We theoretically speculated about this dissociation by relating the mechanical efficiency with Po/a (the curvature of the force-velocity curve) in Hill's characteristic equation of muscle; Po/a is known to change with the energy economy and inversely with Vmax and myosin ATPase activity. The analysis showed that the variability is smaller for the mechanical efficiency than for Po/a and that the energy economy changes approximately with (Po/a)3. These theoretical relations may partly explain the small variability of the empirically observed contractile efficiency under various experimental conditions which are known to widely change the energy economy.

    Fuel economy data contained in the 1996 California Air Resources Board (CARB) report with respect to the introduction of California Reformulated Gasoline (CaRFG) has been examined and reanalyzed by two additional statistical methodologies. Additional data has also been analyzed by these two statistical approaches. Within the assumptions of the analysis, point estimates for the reduction in fuel economy using CaRFG as compared to conventional, non-reformulated gasoline were 2-4%, with a 95% upper confidence bound of 6%. Substantial variations in fuel economy are routine and inevitable due to additional factors which affect mileage, even if there is no change in fuel reformulation. This additional analysis confirms the conclusion reached by CARB with respect to the impact of CaRFG on fuel economy.

  14. The new economy is stronger than you think.

    Many policy makers at the Fed contend that the new economy is a fragile bubble--and that with the "irrational exuberance" of the capital markets, the sky is going to fall on the U.S. economy. That couldn't be further from the truth, according to William Sahlman. As long as the government doesn't interfere, he argues, the economy is sturdy, resilient, and raring to grow. The new economy is strong for several reasons. First, it is based on a business model that works. Any business system that relentlessly drives out inefficiency, forces intelligent business-process reengineering, and gives customers more of what they want will be sustainable. Second, it is built on America's admiration for entrepreneurs and its tolerance for failure, not to mention its easy access to capital. Third, the new economy is attracting the best and brightest minds in the country. And finally, says Sahlman, the new economy is strong because it is spreading. It may be primarily an American phenomenon now, but in a few short years it will start to show its effects everywhere, making the whole world a more productive place. Still, Sahlman believes, the road ahead is not without potholes and sharp curves. But that is what the new economy is all about, he maintains--companies attacking the status quo and entrenched players, companies experimenting to find new technologies that improve or replace earlier ones. Such activity presents no cause for alarm. The economic, social, and cultural factors undergirding the new economy are rock solid. It's simply a matter of letting them stand. PMID:10662008

    We have previously shown that Achilles tendon length is related to walking economy on the flat, presumably because of increased stretch–shortening cycle elastic energy savings. In addition, greater walking economy in African American (AA) women compared to European American (EA) women is explained by longer Achilles tendons in AA women. The purposes of this study were to determine whether economy while walking up a grade and during isometric plantar flexion, two tasks expected to produce proportionately less energy savings from elastic savings are different between AA and EA women. We evaluated walking economy at 4.8 km/h at 0 and 2.5% grade in 48 AA and 48 EA premenopausal women. Plantar flexor muscle metabolic economy (force/ATP) was also evaluated using 31 phosphate magnetic resonance spectroscopy (31P-MRS). AA women walked on the flat more economically (net VO2, AA 8.3 and EA 8.9 ml kg−1 min−1, P = 0.04). No significant ethnic differences were observed while walking up a 2.5% grade or in 31P-MRS determined plantar flexor muscle metabolic economy. These data support our previous study’s suggestion that AA women are more economical while walking on the flat. On the other hand, in activities in which stretch–shortening cycle elastic energy savings would be expected to be reduced (grade walking and isometric force production), no differences in economy during grade walking or isometric force production were observed suggesting that biomechanical, i.e. stretch–shortening cycle elastic energy savings differences rather biochemical differences contribute to the better flat walking economy observed in AA women.

    Resource productivity and evidence of economic decoupling were investigated on the basis of the time series in 1996-2011 of material flow analysis for Sweden, Stockholm, and Gothenburg. In the three cases, absolute reductions in CO2 emissions by about 20% were observed, energy consumption per capita decreased, while gross domestic product (GDP) per capita grew. The energy consumption of the residential and public sectors decreased drastically, while the transport energy consumption is still growing steadily. Decoupling of the economy as a whole (i.e., including materials) is not yet happening at any scale. The domestic material consumption (DMC) continues to increase, in parallel with the GDP. The rate of increase for DMC is slower than that for GDP in both Stockholm and Sweden as a whole (i.e., relative decoupling). The metabolism of the cities does not replicate the national metabolism, and the two cities each have their own distinct metabolism profiles. As a consequence, policy implications for each of the case studies were suggested. In general, because of the necessarily different roles of the two cities in the national economy, generic resource productivity benchmarks, such as CO2 per capita, should be avoided in favor of sectorial benchmarks, such as industry, transport, or residential CO2 per capita. In addition, the share of the city impacts caused by the provision of a service for the rest of the country, such as a port, could be allocated to the national economy. PMID:26065831

    The bio-based economy relies on sustainable, plant-derived resources for fuels, chemicals, materials, food and feed rather than on the evanescent usage of fossil resources. The cornerstone of this economy is the biorefinery, in which renewable resources are intelligently converted to a plethora of products, maximizing the valorization of the feedstocks. Innovation is a prerequisite to move a fossil-based economy toward sustainable alternatives, and the viability of the bio-based economy depends on the integration between plant (green) and industrial (white) biotechnology. Green biotechnology deals with primary production through the improvement of biomass crops, while white biotechnology deals with the conversion of biomass into products and energy. Waste streams are minimized during these processes or partly converted to biogas, which can be used to power the processing pipeline. The sustainability of this economy is guaranteed by a third technology pillar that uses thermochemical conversion to valorize waste streams and fix residual carbon as biochar in the soil, hence creating a carbon-negative cycle. These three different multidisciplinary pillars interact through the value chain of the bio-based economy. PMID:23761802

    Hand, John

    We at the Research Councils believe that there are many aspects of society and business that could be transformed by the innovative design and use of digital technologies. This has led to the Digital Economy Programme. The Digital Economy is an RCUK Cross-Research Council Programme, led by the EPSRC, but working closely with ESRC, MRC, AHRC and TSB. What is Digital Economy? Digital Economy is the novel design or use of information and communication technology to help transform the lives of individuals, society or business. All Digital Economy research involves the user community. This can include industry, government, society, charities or other groups as applicable. The research will understand the technologies and also why change is needed, what the impacts will be and who will benefit. Research in this cross-research council area can be driven by economic, social or technical need. The early involvement of the user community is vital if new technologies are to be integrated successfully into business opportunities, technical solutions or commercial products and processes. Challenges in the Digital Economy will require multi-disciplinary academic input, including, but not limited to, the arts and humanities, economic and social sciences and medical sciences, in addition to engineering and physical sciences.

  20. A theory of family, economy, and gender.

    PubMed

    Huber, J

    1988-03-01

    Historically, the requirements of population replacement have interacted with modes of subsistence technology to shape the differential distribution of power and prestige by sex. Two assumptions undergird Huber's argument: in all societies, producers have more power than consumers; those who control the distribution of valued goods beyond the family have the most power. Evidence comes from societies based on foraging, the hoe, the plow, herding, and industrial technologies. Huber concludes that changes in the work people do have altered the stratification and family systems of plow societies. Declines in mortality and fertility and changes in lactation customs have reduced the time that women spend pregnant or nursing. Increases in educational levels and employment rates enable women to provide sizable shares of family income. These trends have increased the centrality of individual goal attainment in the Western ideational system. Now women, along with men, have been swept into the occupational streams of the industrial revolution, though not quite into the mainstream. Still in question is the extent to which women will hold a fair share of top positions. This will hinge on responsibility for housework and childcare early in a woman's career, a time when most single parents or couples lack resources to command full-time quality care for the daily needs of their children. Ambitious women can avoid much conflict by remaining childless, but that is the point; ambitious men need not make that choice. Women cannot become men's social equals until the most talented women can aspire as realistically as their male counterparts to contribute in proportion to their talents. Thus, the overlap of family, economy, and gender, reshaped by continuing technological change, continues to affect women's status. Industrialization 1st turned the cost-benefit ratio of children upside down. Then wives were drawn into the labor force, raising the opportunity cost of their time, and

    The above quote, taken from the executive summary of the Report from the US DOE Basic Energy Sciences Workshop held August 6–8, 2007,[1] places in context the research carried out at the University of California, Santa Barbara, which is reported in this document. The enormous impact of heterogeneous catalysis is exemplified by the Haber process for the synthesis of ammonia, which consumes a few % of the world’s energy supply and natural gas, and feeds as many as a third of the world’s population. While there have been numerous advances in understanding the process,[2] culminating in the awarding of the Nobel Prize to Gerhard Ertl in 2007, it is interesting to note that the catalysts themselves have changed very little since they were discovered heuristically in the the early part of the 20th century. The thesis of this report is that modern materials chemistry, with all the empirical knowledge of solid state chemistry, combined with cutting edge structural tools, can help develop and better heterogeneous catalysis. The first part of this report describes research in the area of early transition metal carbides (notably of Mo and W), potentially useful catalysts for water gas shift (WGS) and related reactions of use to the hydrogen economy. Although these carbides have been known to be catalytically useful since the 1970s,[3] further use of these relatively inexpensive materials have been plagued by issues of low surface areas and ill-defined, and often unreactive surfaces, in conjunction with deactivation. We have employed for the first time, a combination of constant-wavelength and time-of-flight neutron scattering, including a total scattering analysis of the latter data, to better understand what happens in these materials, in a manner that for the first time, reveals surface graphitic carbon in these materials in a quantitative manner. Problems of preparation, surface stability, and irreversible reactivity have become manifest in this class of materials

    The U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy and the U.S. Environmental Protection Agency (EPA) jointly maintain a fuel economy website (www.fueleconomy.gov), which helps fulfill their responsibility under the Energy Policy Act of 1992 to provide accurate fuel economy information [in miles per gallon (mpg)] to consumers. The site provides information on EPA fuel economy ratings for passenger cars and light trucks from 1985 to the present and other relevant information related to energy use such as alternative fuels and driving and vehicle maintenance tips. In recent years, fluctuations in the price of crude oil and corresponding fluctuations in the price of gasoline and diesel fuels have renewed interest in vehicle fuel economy in the United States. (User sessions on the fuel economy website exceeded 20 million in 2008 compared to less than 5 million in 2004 and less than 1 million in 2001.) As a result of this renewed interest and the age of some of the references cited in the tips section of the website, DOE authorized the Oak Ridge National Laboratory (ORNL) Fuels, Engines, and Emissions Research Center (FEERC) to initiate studies to validate and improve these tips. This report documents a study aimed specifically at the effect of engine air filter condition on fuel economy. The goal of this study was to explore the effects of a clogged air filter on the fuel economy of vehicles operating over prescribed test cycles. Three newer vehicles (a 2007 Buick Lucerne, a 2006 Dodge Charger, and a 2003 Toyota Camry) and an older carbureted vehicle were tested. Results show that clogging the air filter has no significant effect on the fuel economy of the newer vehicles (all fuel injected with closed-loop control and one equipped with MDS). The engine control systems were able to maintain the desired AFR regardless of intake restrictions, and therefore fuel consumption was not increased. The carbureted engine did show a decrease in

Designed for use as a desk-top reference, the data book represents an assembly and display of statistics and information that characterize transportation activity, and presents data on other factors that influence transportation energy use. The purpose of this document is to present relevant statistical data in the form of tables and graphs. Each of the major transportation modes is treated in separate chapters or sections. Chapter 1 compares U.S. transportation data with data from other countries. Aggregate energy use and energy supply data for all modes are presented in Chapter 2. The highway mode, which accounts for over three-fourths of total transportation energy consumption, is dealt with in Chapter 3. Topics in this chapter include automobiles, trucks, buses, fleet vehicles, federal standards, fuel economies, and high- occupancy vehicle lane data. Household travel behavior characteristics are displayed in Chapter 4. Chapter 5 contains information on alternative fuels and alternative fuel vehicles. Chapter 6 covers the major nonhighway modes: air, water, and rail. The last chapter, Chapter 7, presents data on environmental issues relating to transportation.

The situational-analytical centers (SAC) of regional administration The major component of SAC is dynamic modeling, analysis, forecasting and optimization systems, based on modern intellectual information technologies. Spheres of SAC are not only financial streams management and investments optimization, but also strategic forecasting functions, which provide an optimum choice, "aiming", search of optimum ways of regional development and corresponding investments. It is expedient to consider an opportunity of formation of the uniform organizational-methodical center of an industrial policy of region. This organization can be directly connected to the scheduled-analytical services of the largest economic structures, local authorities, the ministries and departments. Such "direct communication" is capable to provide an effective regional development strategic management. Anyway, the output on foreign markets demands concentration of resources and support of authorities. Offered measures are capable to provide a necessary coordination of efforts of a various level economic structures. For maintenance of a regional industrial policy an attraction of all newest methods of strategic planning and management is necessary. Their activity should be constructed on the basis of modern approaches of economic systems management, cause the essence of an industrial policy is finally reduced to an effective regional and corporate economic activities control centers formation.

    Do economic considerations shape attitudes toward immigration? In this article, we consider the relationship between economic interests and immigration preferences by examining how developments in individuals' sectors of employment affect these views. Using survey data across European countries from 2002 to 2009 and employing new measures of industry-level exposure to immigration, we find that sectoral economies shape opinions about immigration. Individuals employed in growing sectors are more likely to support immigration than are those employed in shrinking sectors. Moreover, the economic context matters: Making use of the exogenous shock to national economies represented by the 2008 financial crisis, we show that sector-level inflows of immigrant workers have little effect on preferences when economies are expanding, but that they dampen support for immigration when economic conditions deteriorate and confidence in the economy declines. These sectoral effects remain even when controlling for natives' views about the impact of immigration on the national economy and culture. When evaluating immigration policy, individuals thus appear to take into account whether their sector of employment benefits economically from immigration. PMID:24363457

  20. Renewable Hydrogen Carrier Carbohydrate: Constructing the Carbon-Neutral Carbohydrate Economy

    Zhang, Y.-H. Percival; Mielenz, Jonathan R

    2011-01-01

    Abstract The hydrogen economy presents an appealing energy future but its implementation must solve numerous problems ranging from low-cost sustainable production, high-density storage, costly infrastructure, to eliminating safety concern. The use of renewable carbohydrate as a high-density hydrogen carrier and energy source for hydrogen production is possible due to emerging cell-free synthetic biology technology called cell-free synthetic pathway biotransformation (SyPaB). Assembly of numerous enzymes and co-enzymes in vitro can create complicated set of biological reactions or pathways that microorganisms cannot complete, for example, C6H10O5 (aq) + 7 H2O (l) 12 H2 (g) + 6 CO2 (g) (PLoS One 2007, 2:e456). Thanks to 100% selectivity of enzymes, modest reaction conditions, and high-purity of generated hydrogen, carbohydrate is a promising hydrogen carrier for end users. Gravimetric density of carbohydrate is 14.8 H2 mass% if water can be recycled from PEM fuel cells or 8.33% H2 mass% without water recycling. Renewable carbohydrate can be isolated from plant biomass or would be produced from a combination of solar electricity/hydrogen and carbon dioxide fixation mediated by high-efficiency artificial photosynthesis mediated by SyPaB. The construction of this carbon-neutral carbohydrate economy would address numerous sustainability challenges, such as electricity and hydrogen storage, CO2 fixation and long-term storage, water conservation, transportation fuel production, plus feed and food production.

    Emissions of hydrocarbons from motor vehicles are recognized as major contributors to ozone pollution in urban areas. Petroleum-based motor fuels contain volatile organic compounds (VOC) which, together with oxides of nitrogen, promote the formation of ozone in the troposphere via complex photochemical reactions. VOC emissions from the tailpipe and evaporation from the fuel and engine systems of highway vehicles are believed to account for about 40% of total VOC emissions in any region. But motor fuels also generate emissions throughout the fuel cycle, from crude oil production to refining, storage, transportation, and handling, that can make significant contributions to the total inventory of VOC emissions. Many of these sources of emissions are directly related to the quantity of fuel produced and handled throughout the fuel cycle. It is, therefore, reasonable to expect that a reduction in total fuel throughput might result in a reduction of VOC emissions. In particular, reducing vehicle fuel consumption by increasing vehicle fuel economy should reduce total fuel throughput, thereby cutting total emissions of VOCS. In this report we identify the sources of VOC emissions throughout the motor fuel cycle, quantify them to the extent possible, and describe their dependence on automobile and light truck fuel economy.

  2. Moving toward the circular economy: the role of stocks in the Chinese steel cycle.

    PubMed

    Pauliuk, Stefan; Wang, Tao; Müller, Daniel B

    2012-01-01

    As the world's largest CO(2) emitter and steel producer, China has set the ambitious goal of establishing a circular economy which aims at reconciling economic development with environmental protection and sustainable resource use. This work applies dynamic material flow analysis to forecast production, recycling, and iron ore consumption in the Chinese steel cycle until 2100 by using steel services in terms of in-use stock per capita as driver of future development. The whole cycle is modeled to determine possible responses of the steel industry in light of the circular economy concept. If per-capita stock saturates at 8-12 tons as evidence from industrialized countries suggests, consumption may peak between 2015 and 2020, whereupon it is likely to drop by up to 40% until 2050. A slower growing in-use stock could mitigate this peak and hence reduce overcapacity in primary production. Old scrap supply will increase substantially and it could replace up to 80% of iron ore as resource for steel making by 2050. This would require advanced recycling technologies as manufacturers of machinery and transportation equipment would have to shift to secondary steel as well as new capacities in secondary production which could, however, make redundant already existing integrated steel plants.

    1998-05-01

    In adult humans, the net absorption of dietary copper is approximately 1 mg/d. Dietary copper joins some 4-5 mg of endogenous copper flowing into the gastrointestinal tract through various digestive juices. Most of this copper returns to the circulation and to the tissues (including liver) that formed them. Much lower amounts of copper flow into and out of other major parts of the body (including heart, skeletal muscle, and brain). Newly absorbed copper is transported to body tissues in two phases, borne primarily by plasma protein carriers (albumin, transcuprein, and ceruloplasmin). In the first phase, copper goes from the intestine to the liver and kidney; in the second phase, copper usually goes from the liver (and perhaps also the kidney) to other organs. Ceruloplasmin plays a role in this second phase. Alternatively, liver copper can also exit via the bile, and in a form that is less easily reabsorbed. Copper is also present in and transported by other body fluids, including those bathing the brain and central nervous system and surrounding the fetus in the amniotic sac. Ceruloplasmin is present in these fluids and may also be involved in copper transport there. The concentrations of copper and ceruloplasmin in milk vary with lactational stage. Parallel changes occur in ceruloplasmin messenger RNA expression in the mammary gland (as determined in pigs). Copper in milk ceruloplasmin appears to be particularly available for absorption, at least in rats. PMID:9587137

  5. The moral economy of austerity: analysing UK welfare reform.

    PubMed

    Morris, Lydia

    2016-03-01

    This paper notes the contemporary emergence of 'morality' in both sociological argument and political rhetoric, and analyses its significance in relation to ongoing UK welfare reforms. It revisits the idea of 'moral economy' and identifies two strands in its contemporary application; that all economies depend on an internal moral schema, and that some external moral evaluation is desirable. UK welfare reform is analysed as an example of the former, with reference to three distinct orientations advanced in the work of Freeden (1996), Laclau (2014), and Lockwood (1996). In this light, the paper then considers challenges to the reform agenda, drawn from third sector and other public sources. It outlines the forms of argument present in these challenges, based respectively on rationality, legality, and morality, which together provide a basis for evaluation of the welfare reforms and for an alternative 'moral economy'.

    This paper presents an econometric estimation of the rebound effect for household vehicle travel in the US based on analysis of survey data collected by the Energy Information Administration (EIA) at approximately three-year intervals over a 15-year period. The rebound effect measures the tendency to take back potential energy savings from fuel economy improvements as increased travel. Vehicle use models were estimated for one-, two-, three-, four-, and five-vehicle households. The results confirm recent estimates based on national or state-level data: a long-run take back of about 20% of potential energy savings. Consumer responses to changes in fuel economy or fuel price per gallon appear to be equal and opposite in sign. Recognizing the interdependencies among miles of travel, fuel economy and price is key to obtaining meaningful results.

    Mansell, Robin; Berdou, Evangelia

    Despite the growing amount of research on Free/Libre/Open Source Software (FL/OSS) development, there is little insight into how structural factors associated with institutions influence the patterns of software developer activity in this area. This article examines some of the dynamics of the development of this type of software and the extent to which these dynamics are associated with features of the gift economy as is frequently suggested in the literature. Drawing on an empirical analysis of contributors to the GNOME FL/OSS project, we suggest that greater attention should be given to the emergence of a mixed economy in which features of the exchange economy come to the fore with implications for the power relationships among those contributing to FL/OSS.

    2010-08-01

    The growing complexities of energy systems, environmental problems and technology markets are driving and testing most energy-economy models to their limits. To further advance bottom-up models from a multidisciplinary energy efficiency policy evaluation perspective, we review and critically analyse bottom-up energy-economy models and corresponding evaluation studies on energy efficiency policies to induce technological change. We use the household sector as a case study. Our analysis focuses on decision frameworks for technology choice, type of evaluation being carried out, treatment of market and behavioural failures, evaluated policy instruments, and key determinants used to mimic policy instruments. Although the review confirms criticism related to energy-economy models (e.g. unrealistic representation of decision-making by consumers when choosing technologies), they provide valuable guidance for policy evaluation related to energy efficiency. Different areas to further advance models remain open, particularly related to modelling issues, techno-economic and environmental aspects, behavioural determinants, and policy considerations.

    Objectives To analyze the impact of recent pharmacy graduates on a local economy. Methods Input-output analysis was applied to data from Spokane County, Washington, in 2006 and the findings were reviewed and conclusions were drawn. Results The local college of pharmacy added nearly $1 million (in 2006) directly to the local economy. New pharmacists added nearly $400,000 in direct value. However, because the graduates alleviated a shortage of pharmacists in the area, thereby avoiding both the tangible and intangible (eg, human health) economic costs of a continued shortage, the true economic impact may have been even greater. Conclusions Doctor of pharmacy (PharmD) graduates entering the workforce add substantial value, both to the local retail pharmacy industry specifically and the local economy in general. Thus, the economic impact of the pharmacy practice program training these students is also substantial. PMID:19564989

    The authors investigated the effects of chronic low back pain (LBP) and walking speed (WS) on metabolic power and cost of transport (CT). Subjects with chronic nonspecific LBP (LBP group [LG]; n = 9) and healthy (control group [CG]; n = 9) were included. The test battery was divided into 3 blocks according to WS as follows: preferred self-selected speed (PS), and lower and higher than the PS. In each block, the volunteers walked 5 min, during which oxygen consumption was measured. Although without differences between groups, the LG had CT lower in slower speeds than in faster speeds. Walking speed affected CT only in the LG, which the group had the greatest walking economy at slower speeds. PMID:26403060

    The Center for Transportation Research at the Argonne National Laboratory (ANL) supports the DOE by evaluating advanced automotive technologies in a systems context. ANL has developed a unique set of compatible simulation tools and test equipment to perform an integrated systems analysis project from modeling through hardware testing and validation. This project utilized these capabilities to demonstrate the trade-off in fuel economy and Oxides of Nitrogen (NOx) emissions in a so-called ''pre-transmission'' parallel hybrid powertrain. The powertrain configuration (in simulation and on the dynamometer) consists of a Compression Ignition Direct Ignition (CIDI) engine, a Continuously Variable Transmission (CVT) and an electric drive motor coupled to the CVT input shaft. The trade-off is studied in a simulated environment using PSAT{copyright} with different controllers (fuzzy logic and rule based) and engine models (neural network and steady state models developed from ANL data).

  12. Differences between EPA-test and in-use fuel economy: Are the correction factors correct?

    A vehicle`s in-use or on-the-road fuel economy often differs substantially from the miles-per-gallon estimates developed by the US Environmental Protection Agency (EPA) as part of its emissions certification program. As a result, the certification values are routinely adjusted by a set of correction factors so that the resulting estimates will better reflect in-use experience. Using data from the Residential Transportation Energy Consumption Survey conducted by the Energy Information Administration of the US Department of Energy, our analysis investigated how well the correction factors replicated the shortfall experience of all household vehicles on the road in 1985. Results show that the shortfall is larger than the EPA correction factors, and light trucks are experiencing significantly larger shortfalls than automobiles.

    The political economies of coal in Virginia and Pennsylvania from the late eighteenth century through the Civil War are compared, and the divergent paths these two states took in developing their ample coal reserves during a critical period of American industrialisation are examined. State economic policies played a major role. Virginia's failure to exploit the rich coal fields in the western part of the state can be traced to the legislature's over riding concern to protect and promote the interests of the agrarian, slaveholding elite of eastern Virginia. Pennsylvania's more fractious legislature enthusiastically embraced a policy of economic growth that resulted in the construction of an extensive transportation network, a statewide geological survey, and support for private investment in its coal fields.

  15. Economies of scale and scope in Vietnamese hospitals.

    2004-07-01

    Hospitals consume a large share of health resources in developing countries, but little is known about the efficiency of their scale and scope. The Ministry of Health of Vietnam and World Bank collected data in 1996 from the largest sample ever surveyed in a developing country. The sample included 654 out of 815 public hospitals, six categories of hospitals and a broad range of sizes. These data were used to estimate total variable cost as a function of multiple products, such as admissions and outpatient visits. We report results for two specifications: (1) estimates with a single variable for beds and (2) estimates with interaction terms for beds and the category of hospital. The coefficient estimates were used to calculate marginal costs, short-run returns to the variable factor, economies of scale, and economies of scope for each category of hospital. There were important differences across categories of hospitals. The measure of economies of scale was 1.09 for central general and 1.05 for central specialty hospitals with a mean of 516 and 226 beds, respectively, indicating roughly constant returns to scale. The measure was well below one for both provincial general and specialty hospitals with a mean of 357 and 192 beds, respectively, indicating large diseconomies of scale. The measure was 1.16 for district hospitals and 0.89 other ministry hospitals indicating modest economies and diseconomies of scale, respectively. There were large economies of scope for central and provincial general hospitals. We conclude that in a system of public hospitals in a developing country that followed an administrative structure, the variable cost function differed significantly across categories of hospitals. Economies of scale and scope depended on the category of the hospital in addition to the number of beds and volume of output. PMID:15087154

    Irvine, John T. S.

    This paper focuses on the critical role of power sources in the future energy economy. It highlights the disruptive nature of the new energy technologies that will come into play, addressing the problems of greenhouse emissions and reduced availability of fossil fuel reserves. The importance of power sources such as fuel cells and batteries is discussed and their inter-relationship with the hydrogen economy explored. Overall it is clear that improved methods of energy storage are of critical importance and these must be optimised both in terms of cost and energy density. There are important challenges to be addressed; however, very positive outcomes can be anticipated.

    This paper, using a six-region dynamic stochastic general equilibrium model of the world economy, assesses the output and current account implications of permanent oil supply shocks hitting the world economy. For modest-sized shocks and conventional production technologies, the effects are modest. But for larger shocks, for elasticities of substitution that decline as oil usage is reduced to a minimum, and for production functions in which oil acts as a critical enabler of technologies, output growth could drop significantly. Also, oil prices could become so high that smooth adjustment, as assumed in the model, may become very difficult. PMID:24298081

    The coming of knowledge economy creates unprecedented situation of economy development. The trend of education's globalization as well as communication means frequently updated severely hit the system of financial management. Along with the deep going of education industrialization, and development of logistics management socialization, system and content of university financial management are increasingly expending and getting more and more complex that result in new challenge and problems to financial management. In order to step up with university development of internationalization and the logistics development of socialization, the financial management has to reform in response to this new challenge and trend.

    A comparison of the relative economy of airplane construction shows that monoplanes are cheaper than biplanes; that all-metal construction is much more expensive than mixed construction; that multi-engine airplanes are more expensive than single-engine types of the same carrying capacity and speed;that the cost of airplanes is materially reduced by increasing their size without increasing the number of engines. The greatest economy usually coincides with the best aerodynamic and static conditions and the cost is always increased by safety requirements.

    Despite advanced scientific and technological (S&T) expertise, the Russian economy is presently based upon manufacturing and raw material exports. Currently, governmental incentives are attempting to leverage the existing scientific infrastructure through the concept of building a Knowledge Based Economy. However, socio-economic changes do not occur solely by decree, but by alteration of approach to the market. Here we describe the "Guided Entrepreneurship" plan, a series of steps needed for generation of an army of entrepreneurs, which initiate a chain reaction of S&T-driven growth. The situation in Russia is placed in the framework of other areas where Guided Entrepreneurship has been successful.

  1. Proton Transport

    NASA Technical Reports Server (NTRS)

    2001-01-01

    The transport of protons across membranes is an essential process for both bioenergetics of modern cells and the origins of cellular life. All living systems make use of proton gradients across cell walls to convert environmental energy into a high-energy chemical compound, adenosine triphosphate (ATP), synthesized from adenosine diphosphate. ATP, in turn, is used as a source of energy to drive many cellular reactions. The ubiquity of this process in biology suggests that even the earliest cellular systems were relying on proton gradient for harvesting environmental energy needed to support their survival and growth. In contemporary cells, proton transfer is assisted by large, complex proteins embedded in membranes. The issue addressed in this Study was: how the same process can be accomplished with the aid of similar but much simpler molecules that could have existed in the protobiological milieu? The model system used in the study contained a bilayer membrane made of phospholipid, dimyristoylphosphatidylcholine (DMPC) which is a good model of the biological membranes forming cellular boundaries. Both sides of the bilayer were surrounded by water which simulated the environment inside and outside the cell. Embedded in the membrane was a fragment of the Influenza-A M$_2$ protein and enough sodium counterions to maintain system neutrality. This protein has been shown to exhibit remarkably high rates of proton transport and, therefore, is an excellent model to study the formation of proton gradients across membranes. The Influenza M$_2$ protein is 97 amino acids in length, but a fragment 25 amino acids long. which contains a transmembrane domain of 19 amino acids flanked by three amino acids on each side. is sufficient to transport protons. Four identical protein fragments, each folded into a helix, aggregate to form small channels spanning the membrane. Protons are conducted through a narrow pore in the middle of the channel in response to applied voltage. This

  4. Transportation needs assessment: Emergency response section

    1989-05-01

    The transportation impacts of moving high level nuclear waste (HLNW) to a repository at Yucca Mountain in Nevada are of concern to the residents of the State as well as to the residents of other states through which the nuclear wastes might be transported. The projected volume of the waste suggests that shipments will occur on a daily basis for some period of time. This will increase the risk of accidents, including a catastrophic incident. Furthermore, as the likelihood of repository construction and operation and waste shipments increase, so will the attention given by the national media. This document is not to be construed as a willingness to accept the HLNW repository on the part of the State. Rather it is an initial step in ensuring that the safety and well-being of Nevada residents and visitors and the State`s economy will be adequately addressed in federal decision-making pertaining to the transportation of HLNW into and across Nevada for disposal in the proposed repository. The Preferred Transportation System Needs Assessment identifies critical system design elements and technical and social issues that must be considered in conducting a comprehensive transportation impact analysis. Development of the needs assessment and the impact analysis is especially complex because of the absence of information and experience with shipping HLNW and because of the ``low probability, high consequence`` aspect of the transportation risk.
