    2015-04-01

    Governments and donors are investing considerable resources on HIV prevention in order to scale up these services rapidly. Given the current economic climate, providers of HIV prevention services increasingly need to demonstrate that these investments offer good 'value for money'. One of the primary routes to achieve efficiency is to take advantage of economies of scale (a reduction in the average cost of a health service as provision scales-up), yet empirical evidence on economies of scale is scarce. Methodologically, the estimation of economies of scale is hampered by several statistical issues preventing causal inference and thus making the estimation of economies of scale complex. In order to estimate unbiased economies of scale when scaling up HIV prevention services, we apply our analysis to one of the few HIV prevention programmes globally delivered at a large scale: the Indian Avahan initiative. We costed the project by collecting data from the 138 Avahan NGOs and the supporting partners in the first four years of its scale-up, between 2004 and 2007. We develop a parsimonious empirical model and apply a system Generalized Method of Moments (GMM) and fixed-effects Instrumental Variable (IV) estimators to estimate unbiased economies of scale. At the programme level, we find that, after controlling for the endogeneity of scale, the scale-up of Avahan has generated high economies of scale. Our findings suggest that average cost reductions per person reached are achievable when scaling-up HIV prevention in low and middle income countries. PMID:25779621

    This paper analyzes the Portuguese short-run business cycles over the last 150 years and presents the multidimensional scaling (MDS) for visualizing the results. The analytical and numerical assessment of this long-run perspective reveals periods with close connections between the macroeconomic variables related to government accounts equilibrium, balance of payments equilibrium, and economic growth. The MDS method is adopted for a quantitative statistical analysis. In this way, similarity clusters of several historical periods emerge in the MDS maps, namely, in identifying similarities and dissimilarities that identify periods of prosperity and crises, growth, and stagnation. Such features are major aspects of collective national achievement, to which can be associated the impact of international problems such as the World Wars, the Great Depression, or the current global financial crisis, as well as national events in the context of broad political blueprints for the Portuguese society in the rising globalization process.

    Seeks evidence concerning the issues of the relative efficiencies of different institutional arrangements for pollution control and the implications of control requirements for economies of scale and barriers to entry. Data is derived from the estimation of a production function for 30 pulp and paper mills in Wisconsin and Michigan. Concludes that the systematic differences in marginal treatment costs for different mills are evidence of serious inefficiencies resulting from the current (US) system of pollution control regulation. The positive association of pollution control intensity with economies of scale suggests that any pollution control regime has some negative allocational effects in this industry (and presumably others). -K.Turner

    Considine, T.J.

    1999-12-01

    While innovative trading tools have become an increasingly important aspect of the electricity business, the future of any firm in the industry boils down to a basic bread and butter issue of generating power at competitive costs. While buying electricity from power pools at spot prices instead of generating power to service load may be profitable for some firms in the short run, the need to efficiently utilize existing plants in the long run remains. These competitive forces will force the closure of many inefficient plants. As firms close plants and re-evaluate their generating asset portfolios, the basic structure of the industry will change. This article presents some quantitative analysis that sheds light on this unfolding transformation.

    Given, R S

    1996-12-01

    This paper tests for the existence and magnitude of economies of scale and scope as possible explanations for the recent observed trends in increasing health maintenance organization (HMO) scale (through merger and acquisition) and scope (through greater participation in public enrollee markets) using firm level data from a sample of California HMOs for the time period 1986-1992. The results suggest that economies of scale provide a strong justification for mergers only in the case of relatively small HMOs (i.e. those with fewer than 115,000 enrollees), and economies of scope do not explain the increasing HMO enrollment of public enrollees.

    1981-01-01

    This paper examines two components of the hospital insurance market structure-market share and the absolute number of enrollees in Blue Cross plans-to ascertain whether market structure affects the willingness of Blue Cross plans to use cost control measure. Empirical estimates show that larger plans are more likely to use prospective reimbursement, pre-admission testing, and concurrent review. Market share, however, has a positive effect only on concurrent review. We suggest that there are economies of scale to cost control efforts, but that high market share generally does not lead to increased cost-consciousness. PMID:7263273

  18. Theory and evidence of economies of scale in the development of waste management systems

    1989-01-01

    Waste is a cost of doing business. This cost can be considered in terms of the potential adverse health and environmental impacts, or the waste management costs associated with avoiding, minimizing, and controlling those impacts. There is an anticipated increase in the cost of waste management as a result of the increasing requirements for regulatory compliance. To meet the total waste management capacity needs of the organization and the compliance requirements, low-level radioactive, hazardous, and mixed waste management will need demonstrated technologies strategically managed as a technology portfolio. The role of the decision maker is to select the optimum mix of technologies and facilities to provide the waste management capacity needed for the next twenty years. The waste management system resulting from this mix includes multiple small-scale fixed facilities, large-scale centralized facilities, and waste management subcontracts. This study was conducted to examine the theory and evidence of economies of scale in the development of waste management systems as as exploratory research on the economic considerations in the process of technology selection and implementation. 25 refs., 24 figs., 11 tabs.

  19. Reforming the wastewater treatment sector in Italy: Implications of plant size, structure, and scale economies

    NASA Astrophysics Data System (ADS)

    Fraquelli, Giovanni; Giandrone, Roberto

    2003-10-01

    In the context of the restructuring of the water industry, this work examines the treatment processes of urban wastewaters in Italy, with reference to costs, size, and technology. The operating cost function of 103 plants confirms scope economies from vertical integration and strong economies of scale for the smaller structure, confirming the benefits coming from the aggregation of the existing little firms. A minimum efficient size at about 100,000 inhabitants, however, inhibits the creation of large monopolies at a local level and enables the maintenance of indirect competition. Among the explanatory variables of running costs, the pollution load of the input wastewater takes on a high statistical significance and suggests environmental prevention, while the strong impact of sludge concentration means it should be considered in the new tariff systems. The recent introduction of advanced treatments is expensive, but the costs are balanced by a notable improvement in the pureness of the effluent waters. As for general environmental policies, it is necessary to find a good compromise between the need to improve the effectiveness of the existing plants and the investments in areas where the water treatment service is still inexistent.

    In foraging and other productive activities, individuals make choices regarding whether and with whom to cooperate, and in what capacities. The size and composition of cooperative groups can be understood as a self-organized outcome of these choices, which are made under local ecological and social constraints. This article describes a theoretical framework for explaining the size and composition of foraging groups based on three principles: (i) the sexual division of labour; (ii) the intergenerational division of labour; and (iii) economies of scale in production. We test predictions from the theory with data from two field contexts: Tsimane' game hunters of lowland Bolivia, and Jenu Kuruba honey collectors of South India. In each case, we estimate the impacts of group size and individual group members' effort on group success. We characterize differences in the skill requirements of different foraging activities and show that individuals participate more frequently in activities in which they are more efficient. We evaluate returns to scale across different resource types and observe higher returns at larger group sizes in foraging activities (such as hunting large game) that benefit from coordinated and complementary roles. These results inform us that the foraging group size and composition are guided by the motivated choice of individuals on the basis of relative efficiency, benefits of cooperation, opportunity costs and other social considerations.

    For a successful adaptation strategy, it is necessary to have an in-depth understanding of the economic consequences of a flood. To assess the economic consequences of large-scale river floods in Europe, we introduce an integrated direct and indirect risk model for the European economy as a whole. The proposed methodology consists of multiple steps. First, a direct loss assessment is conducted for the 50 largest river basin districts in Europe, based on simulated floods for several return periods. Second, the direct losses in capital and labour are translated into the loss in production per sector. Third, the recovery of this production shock is modelled using a hybrid interregional input-output model, combining non-linear programming and input-output modelling. This combination makes it possible to find (1) the possible production losses in the affected regions and other European regions, (2) the required production in Europe to satisfy additional reconstruction demands from the affected regions and (3) the required production in other regions that is necessary to take over lost production in the affected region. Consequently, when knowing how much production is lost (or gained) in each region, the economic consequences can be assessed. Finally, the model outcome is loss estimation expressed in terms of expected annual damage. To assess these consequences, interregional supply and use tables are used, consisting of 256 different European NUTS2 regions. This data makes it possible to model the indirect losses for both the affected regions and the rest of Europe in detail. By combining the outcomes of all floods in all the river basin districts, it is possible to determine the flood risk of each region in Europe, even when a region is not directly hit by a flood. Consequently, the overall consequences for the European Union are found to be positive for small-scale floods and negative for large-scale floods.

    2014-01-01

    The scale-up of the Knoevenagel-condensation between vanillin and barbituric acid carried out in planetary ball mills is investigated from an engineering perspective. Generally, the reaction proceeded in the solid state without intermediate melting and afforded selectively only one product. The reaction has been used as a model to analyze the influence and relationship of different parameters related to operation in planetary ball mills. From the viewpoint of technological parameters the milling ball diameter, dMB, the filling degree with respect to the milling balls' packing, ?MB,packing, and the filling degree of the substrates with respect to the void volume of the milling balls' packing, ?GS, have been investigated at different reaction scales. It was found that milling balls with small dMB lead to higher yields within shorter reaction time, treaction, or lower rotation frequency, rpm. Thus, the lower limit is set considering the technology which is available for the separation of the milling balls from the product after the reaction. Regarding ?MB,packing, results indicate that the optimal value is roughly 50% of the total milling beakers' volume, VB,total, independent of the reaction scale or reaction conditions. Thus, 30% of VB,total are taken by the milling balls. Increase of the initial batch sizes changes ?GS significantly. However, within the investigated parameter range no negative influence on the yield was observed. Up to 50% of VB,total can be taken over by the substrates in addition to 30% for the total milling ball volume. Scale-up factors of 15 and 11 were realized considering the amount of substrates and the reactor volume, respectively. Beside technological parameters, variables which influence the process itself, treaction and rpm, were investigated also. Variation of those allowed to fine-tune the reaction conditions in order to maximize the yield and minimize the energy intensity. PMID:25406485

    2015-09-01

    This paper reviews the economic research on obesity, covering topics such as the measurement of, and trends in, obesity, the economic causes of obesity (e.g. the monetary price and time cost of food, food assistance programs, income, education, macroeconomic conditions, and peer effects), and the economic consequences of obesity (e.g. lower wages, a lower probability of employment, and higher medical care costs). It also examines the extent to which obesity imposes negative externalities, and economic interventions that could potentially internalize such externalities, such as food taxes, subsidies for school-based physical activity programs, and financial rewards for weight loss. It discusses other economic rationales for government intervention with respect to obesity, such as imperfect information, time inconsistent preferences, and irrational behavior. It concludes by proposing a research agenda for the field. Overall, the evidence suggests that there is no single dominant economic cause of obesity; a wide variety of factors may contribute a modest amount to the risk. There is consistent evidence regarding the economic consequences of obesity, which are lower wages and higher medical care costs that impose negative externalities through health insurance. Studies of economic approaches to preventing obesity, such as menu labeling, taxes on energy-dense foods, and financial rewards for weight loss find only modest effects on weight and thus a range of policies may be necessary to have a substantial effect on the prevalence of obesity.

    The use of body mass index values (BMI) to measure living standards is now a well-accepted method in economics. Nevertheless, a neglected area in historical studies is the relationship between 19th century BMI and family size, and this relationship is documented here to be positive. Material inequality and BMI are the subject of considerable debate, and there was a positive relationship between BMI and wealth and an inverse relationship with inequality. After controlling for family size and wealth, BMI values were related with occupations, and farmers and laborers had greater BMI values than workers in other occupations. PMID:25555643

    A nontechnical discussion of the political economy of the world oil market is intended to inform the beginning student as well as serve as a reference book. Beginning with definitions and an explanation of units, the text covers the world economy, oil supply, oil prices, oil consumption and non-oil energy materials supplies, oil companies, macroeconomics, and the market in an effort to relate both macro- and microeconomic phenomena. Professor Banks feels that population is the most crucial factor in economics today, followed by nonfuel minerals and energy; the technical problems pertaining to energy, however, can be managed if the first two are faced and dealt with. He thinks the outlook is good for replacing oil with other energy sources. 143 references, 23 figures, 26 tables. (DKC)

    Objective Policy-makers have long argued about the potential efficiency gains and cost savings from integrating HIV and sexual reproductive health (SRH) services, particularly in resource-constrained settings with generalised HIV epidemics. However, until now, little empirical evidence exists on whether the hypothesised efficiency gains associated with such integration can be achieved in practice. Methods We estimated a quadratic cost function using data obtained from 40 health facilities, over a 2-year-period, in Kenya and Swaziland. The quadratic specification enables us to determine the existence of economies of scale and scope. Findings The empirical results reveal that at the current output levels, only HIV counselling and testing services are characterised by service-specific economies of scale. However, no overall economies of scale exist as all outputs are increased. The results also indicate cost complementarities between cervical cancer screening and HIV care; post-natal care and HIV care and family planning and sexually transmitted infection treatment combinations only. Conclusions The results from this analysis reveal that contrary to expectation, efficiency gains from the integration of HIV and SRH services, if any, are likely to be modest. Efficiency gains are likely to be most achievable in settings that are currently delivering HIV and SRH services at a low scale with high levels of fixed costs. The presence of cost complementarities for only three service combinations implies that careful consideration of setting-specific clinical practices and the extent to which they can be combined should be made when deciding which services to integrate.

    2004-06-01

    The general ecological situation of Loess Plateau is kept deteriorating, despite great efforts have been made and some achievements were gained after 50 years' endeavor to control soil erosion and renovate ecological landscape. Investigations on the past 20 years results from 11 experimental sites showed that the extension of prototypes and models derived from these sites, which were all based on one scale of small watershed, were unsatisfactory. The possible reasons for such a situation could be attributed to the too coarse scale of map, on which, the regional planning were set up and the locations of these experiment sites were decided, the too fine scale of the small watershed which were usually 3-10 km2 in size, the shortage of studies on various scales particularly on the meso-scale, and the lack of methods of scaling on up-scaling. Based on the analysis of restraints in management of small watershed, the specific concept and relevant proposed methods of resemblance-scaling and multi-scale complementarity were put forward and tested.

    For urban economies, an ecological endowment embodiment analysis has to be supported by endowment intensities at both the international and domestic scales to reflect the international and domestic imports of increasing importance. A three-scale input-output modeling for an urban economy to give nine categories of embodiment fluxes is presented in this paper by a case study on the carbon dioxide emissions by the Beijing economy in 2007, based on the carbon intensities for the average world and national economies. The total direct emissions are estimated at 1.03E+08 t, in which 91.61% is energy-related emissions. By the modeling, emissions embodied in fixed capital formation amount to 7.20E+07 t, emissions embodied in household consumption are 1.58 times those in government consumption, and emissions in gross capital formation are 14.93% more than those in gross consumption. As a net exporter of carbon emissions, Beijing exports 5.21E+08 t carbon embodied in foreign imported commodities and 1.06E+08 t in domestic imported commodities, while emissions embodied in foreign and domestic imported commodities are 3.34E+07 and 1.75E+08 t respectively. The algorithm presented in this study is applicable to the embodiment analysis of other environmental resources for regional economies characteristic of multi-scales.

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

  20. The effectiveness of small scale Photovoltaic (PV) systems design and cost analysis simulation on Saudi Arabian Economy

    Almansour, Faris Abdullah

    The advantages of Renewable Energy Sources (RES) are much more than the disadvantages, RES such as solar, wind energy, biomass, and geothermal, which can be used for generating distributed power but cannot directly replace the existing electric energy grid technologies. The latter are far too well established to abandon, while the new RES technologies are not sufficiently developed to meet the total energy demand. Therefore, it is sensible to gradually infuse RES into existing grids and transform the system over time Saudi Arabia (SA) is a semi-developed nation with a population of over twenty nine million people. It is the largest country in western Asia with an area of 2.225MKm2. SA's largest export is oil, owning 1/5 of the world's supply, and producing twelve million barrels a day. However, SA is far behind in developing a smart grid and RES. A lot of this is to do with lack of participation by both the government and the private business sector. Currently SA spends over $13B a year on generating electricity from oil. SA is the largest consumer of petroleum in the Middle East, due to the high demand for transportation and electricity generation. According to the Saudi electrical company, the total amount of generated power in 2011 was 190.280GW. In addition, SA's electricity consumption is currently growing 8% a year. SA aims to generate 55GW of renewable energy by 2020, in order to free up fossil fuels for export. 41GW of the 55GW will be generated from solar energy. Smart grid technologies are also under consideration in SA; this will allow an efficient and reliable way to control the energy in the future. In addition, the potential for wind and geothermal energy is very high. In this thesis, there is a full exploration of RES components which are critical to manage carbon emission and the limitations of the current grid to the new RES technologies, which face barriers to full-scale deployment. A study in Dhahran, SA has been simulated on a installing a Dual-Tariff PV system using HOMER. The result of the simulation has been discussed, analyzed, and plotted. We also give evidence in the thesis how useful the small PV systems can be as oppose to the larger scale system that must deal with location issues.

    Business incubators such as Hotbank, CMGI, and Idealab! are a booming industry. Offering office space, funding, and basic services to start-ups, these organizations have become the hottest way to nurture and grow fledgling businesses. But are incubators a fleeting phenomenon born of an overheated stock market, or are they an important and lasting way of creating value and wealth in the new economy? The authors argue that one type of incubator, called a networked incubator, represents a fundamentally new and enduring organizational model uniquely suited to growing businesses in the Internet economy. It shares certain features with other incubators--mainly, it fosters a spirit of entrepreneurship and offers economies of scale. But its key distinguishing feature is its ability to give start-ups preferential access to a network of potential partners. Such incubators institutionalize their networking--they have systems in place to encourage networking, helping start-ups, for example, to meet with potential business allies. That doesn't mean incubatees get preferential treatment; it means only that they have built-in access to partnerships that might not have existed without the incubator. Even with this advantage, however, networked incubators can easily follow the road to ruin. To avoid failure, they must create a portfolio of companies and advisers that their incubatees can leverage. That can be done by strategically investing in portfolio firms and by enlisting a large set of business allies. It can also be done by establishing connections and relationships that are anchored more to the incubator than to particular individuals. PMID:11143156

  6. The economy of solar energy

    1994-12-31

    Solar energy is often regarded as environmentally-friendly, but, at the same time as not economical. A global economical view shows, however, that renewable energies can bring about substantial economic and social benefits today, even before their wide market introduction has begun. They are a basic economic innovation for durably overcoming the ever increasing risk innate in the current economic development: they provide new jobs in industry, crafts, and agriculture; a long-term reduction of administrative and health costs; reduced subsidies, increased foreign exchange assets for national economies; reduced military expenses to secure the energy supply structure; and preservation of agriculture on a sustainable basis. In the medium- and long-term, they are a precondition for reducing operation and management costs of the energy supply system. On the basis of a completely new tax system - the entropy tax - solar energy can become the trigger of a new economic dynamics which remains within the ecological limits of growth. 27 refs., 2 figs., 4 tabs.

  9. Burma: the political economy of violence.

    PubMed

    Brown, C

    1999-09-01

    Protracted conflict and violence in Burma have been conducive to the growth of the opium industry, Burma's single financial success in recent years of economic crisis and authoritarian rule. This in turn has fed violence and subsequent humanitarian crisis. This paper argues that the underlying political economy of the conflict has been overlooked, while conflict itself has been treated as a peripheral factor in questions of 'development', and further that the opium dynamic is a vital factor in continued violence and vulnerability for non-combatants in the region. A political economy approach, identifying the beneficiaries of violence, will offer a more holistic and effective approach to the protracted crisis. PMID:10509057

    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.

  2. Dynamic systems of regional economy management optimization

    NASA Astrophysics Data System (ADS)

    Trofimov, S.; Kudzh, S.

    One of the most actual problems of the Russian economic life is a regional economic systems formation. The hierarchy of economic and branch priorities should follow from the general idea of an industrial policy. The matter is that the concept of an industrial policy is defined by the system of priorities mainly incorporated in it. The problem of priorities is not solved yet neither on federal, nor at a regional level. It is necessary to recognize, that a substantiation of this or that variant of priorities - objectively a challenge. Such substantiation can be received with the help of dynamic structural modeling and management technology. At formation of the regional industrial policy program the special attention is given to creation of modern type commercial structures. In regions there are headquarters and branches of many largest corporations, holdings and banks. Besides it, many regional enterprises already became inter-regional or even the transnational companies. In this connection an assistance of transformation of the industrial enterprises and their groups in vertically integrated companies and modern type holdings can become a prominent aspect of an industrial policy. Regional economic structures should be reconstructed gradually on the general model of the world class competitive companies. Assistance to creation of new corporational control systems, the organization of headquarters and the central services work - all this can be included into the sphere of regional administration industrial policy. The special attention should be turned on necessity of development of own system of the corporate structures, capable to provide to the region an independent participation in use of the natural resources and industrial-technological potential, at the stage of a regional industrial policy program formation. Transformation of the industrial enterprises and their groups into modern type vertically-integrated companies and holdings can become one of the major directions of an industrial policy of region. 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. Opportunities of optimum regional economy planning and management as uniform system Approaches to planning regional economic systems can be different. We will consider some most effective methods of planning and control over a regional facilities condition. All of them are compact and evident, that allows to put them into the group of average complexity technologies. At the decision of problems of a regional resource management is rather perspective the so-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 enterprises taxes, etc. What purposes are the specified methods applied to? The regional companies management and their reforming. One of the major directions - transformation of the enterprises into the viable industrial companies, an effective economic structures formation. In this connection, the technology of financial streams management allows to solve another important problem. The created (or reorganized) structure can be checked up in various economic modes even before practical realization of the project. The received data can be applied to an indicative plans substantiation and control over their performance. They can be used at negotiations with the enterprises heads, which are spent for interests of a regional industrial policy. Such approach can become base for concrete (as figures, plans and schemes) coordination of long-term investment priorities of the largest firms and companies, their production programs coordination, the mutual markets formation and the cooperation communications stabilization, payment chains, the social and economic development programs creation. It opens opportunities for the regional branches, enterprises, the major economic centers coordinated management. An effective planning of price pools, investment programs, the control over tax revenues and financial streams becomes possible. All this are necessary elements of a regional authorities economic policy. The offered approach considerably surpasses by it's efficiency auditor, "paper" or traditional computer technology. Bulky computer centers are not capable to cope with the given class problems. At the same time the small mobile commissions of experts "armed" with modern intellectual technologies, are capable to solve rather scale analytical problems. On the basis of the offered methods can be generated means of automation of the regional industrial complex development management. They are focused on concrete objects of various scale: territorial complexes, branches, groups of the companies, the separate enterprises. Thus, the program of a regional industrial policy can be put on an effective scheduled-analytical basis.

    Domestic public debate continues over the economic impacts of environmental regulations that require environmental restoration. This debate has occurred in the absence of broad-scale empirical research on economic output and employment resulting from environmental restoration, restoration-related conservation, and mitigation actions — the activities that are part of what we term the “restoration economy.” In this article, we provide a high-level accounting of the size and scope of the restoration economy in terms of employment, value added, and overall economic output on a national scale. We conducted a national survey of businesses that participate in restoration work in order to estimate the total sales and number of jobs directly associated with the restoration economy, and to provide a profile of this nascent sector in terms of type of restoration work, industrial classification, workforce needs, and growth potential. We use survey results as inputs into a national input-output model (IMPLAN 3.1) in order to estimate the indirect and induced economic impacts of restoration activities. Based on this analysis we conclude that the domestic ecological restoration sector directly employs ~ 126,000 workers and generates ~ $9.5 billion in economic output (sales) annually. This activity supports an additional 95,000 jobs and $15 billion in economic output through indirect (business-to-business) linkages and increased household spending. PMID:26083034

  5. 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.

    On average, brain network economy represents a trade-off between communication efficiency, robustness, and connection cost, although an analogous understanding on an individual level is largely missing. Evaluating resting-state networks of 42 healthy participants with seven Tesla functional magnetic resonance imaging 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 three-dimensional 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 three 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

    A political economic purview of energy conservation in the United States was delineated. The concepts of substitution and elasticity are distinguished, and further distinctions are made between short run price elasticity, cross price elasticity, and available fund elasticity. An assessment of the role which cost factors can play in conservation is given. The structure of the petroleum industry and foreign petroleum resources is discussed. Also discussed is the role of government, industry and the consumer with the economic sphere.

  8. Political economy of hospital financing.

    PubMed

    Breyer, F; Schneider, F

    1992-01-01

    In this paper we tried to explain the recent reform in the law of financing German hospitals. We first described five basic types of hospital payment systems which were available as alternatives to the decision on the reform in the early 1980s. In the next step we identified five concerned interest groups whose actions certainly had a great influence on the legislative process. We proposed a simple theoretical model to examine how these groups of actors evaluated the different payment systems. After deriving a preference ranking for each actor, we confronted these rankings with the respective revealed preferences, which could be inferred from their official statements towards the reform. It could also be shown that quite often the actual statements deviated strongly from the theoretically expected preferences because all groups were engaged in a highly interactive lobbying game. In the last step we compared these preferences to the actual outcome of the legislation and found that all groups have at least partly realized their targets. So in contrast to the typical results of interest group theory, the differences in bargaining power do to appear to have led to a solution which unambiguously benefits some groups of actors at the expense of others. It has to be repeated that the empirical analysis was limited to statements from the interest groups in the pre-legislative stage of the whole process. From this point the most promising procedure would appear to be the step-by-step analysis of the statements of the groups during the legislative process as well. This would give the researcher a chance to evaluate whether or not the theoretical hypotheses can be confirmed, whether or not our simple theoretical model is an appropriate way to understand the behavior of the affected groups and what was finally responsible for the outcome of the legislation. Therefore this paper should be seen as a first attempt to apply the framework of public choice theory to the field of health care financing and to demonstrate that much more research is needed.

    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.

    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.

  9. The Political economy of world energy

    SciTech Connect

    Clark, J.G.

    1990-01-01

    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.

  10. Health benefits of a low carbon economy.

    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

    Satellites acquire information on a global and repetitive basis. They are thus ideal tools for use when global scale and analysis over time is required. Data from satellites comes in digital form which means that it is ideally suited for incorporation in digital data bases and that it can be evaluated using automated techniques. The development of a global multi-source data set which integrates digital information is proposed regarding some 15,000 major industrial sites worldwide with remotely sensed images of the sites. The resulting data set would provide the basis for a wide variety of studies of the global economy. The preliminary results give promise of a new class of global policy model which is far more detailed and helpful to local policy makers than its predecessors. The central thesis of this proposal is that major industrial sites can be identified and their utilization can be tracked with the aid of satellite images.

    1998-04-01

    To account quantitatively for many reported "natural" fat tail distributions in Nature and Economy, we propose the stretched exponential family as a complement to the often used power law distributions. It has many advantages, among which to be economical with only two adjustable parameters with clear physical interpretation. Furthermore, it derives from a simple and generic mechanism in terms of multiplicative processes. We show that stretched exponentials describe very well the distributions of radio and light emissions from galaxies, of US GOM OCS oilfield reserve sizes, of World, US and French agglomeration sizes, of country population sizes, of daily Forex US-Mark and Franc-Mark price variations, of Vostok (near the south pole) temperature variations over the last 400 000 years, of the Raup-Sepkoski's kill curve and of citations of the most cited physicists in the world. We also discuss its potential for the distribution of earthquake sizes and fault displacements. We suggest physical interpretations of the parameters and provide a short toolkit of the statistical properties of the stretched exponentials. We also provide a comparison with other distributions, such as the shifted linear fractal, the log-normal and the recently introduced parabolic fractal distributions.

    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.

    An integrated ecological evaluation of the Beijing economy was presented in the paper based on the emergy accounting with the data in 2004. Through calculating environmental and economic inputs within and outside the Beijing economy, this paper discusses the Beijing's resource structure, economic situation and trade status based on a series of emergy indicators. Through the comparison of the systematic indicators of Beijing with those of the selected Chinese cities, the general status of the Beijing economy in China is identified. The results also show that most indicators of Beijing are located at middle levels among the selected Chinese cities. Particularly, the environmental impacts, expressed by the ratio of waste to the renewable emergy, and the ratio of waste to the total emergy use, are 84.2 and 0.26, respectively in Beijing in 2004, which indicate that the Beijing economy is greatly reliant on the imported intensive fuels, goods and services with high empower density and environmental loading.

  18. 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 thereby the cost of children. Now, below-replacement fertility in the West has highlighted the problem of population maintenance. Parenthood may have to be made more attractive by limiting the hours of responsibility. Such measures would be expensive but they would raise women's status in the family and in society in ways that were unimaginable a few decades ago. PMID:12281313

    Fuel economy data contained in the 1996 California Air Resources Board (CAROB) 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 CAROB with respect to the impact of CaRFG on fuel economy.

  1. Use of DRACS to Enhance HTGRs Passive Safety and Economy

    2011-06-01

    This paper discusses the use of DRACS to Enhance HTGRs Passive Safety and Economy. One of the important requirements for Gen. IV High Temperature Gas Cooled Reactors (HTGR) is passive safety. Currently all the HTGR designs use Reactor Vessel Auxiliary Cooling System (RVACS) for passive decay heat removal. [1] The decay heat first is transferred to core barrel by conduction and radiation, and then to reactor vessel by thermal radiation and convection; finally the decay heat is transferred to natural circulated air or water systems. RVACS can be characterized as a surface based decay heat removal system. Similar concepts have been widely used in sodium cooled fast reactor (SFR) designs, advanced light water reactors like AP1000. The RVACS is especially suitable for smaller power reactors since small systems have relatively larger surface area. RVACS tends to be less expensive. However, it limits the largest achievable power level for modular HTGRs due to the mismatch between the reactor power (proportional to volume) and decay heat removal capability (proportional to surface). When the relative decay heat removal capability is reduced, the peak fuel temperature increases, even close to the design limit. Annual designs with internal reflector can mitigate this effect therefore further increase the power. Another way to increase power is to increase power density. However, it is also limited by the decay heat removal capability. Besides safety, HTGRs also need to be economical in order to compete with other reactor designs. The limit of decay heat removal capability set by using RVACS has affected the economy of HTGRs. Forsberg [2] pointed out other disadvantages of using RVACS such as conflicting functional requirements for the reactor vessel and scaling distortion for integral effect test of the system performance. A potential alternative solution is to use a volume based passive decay removal system, call Direct Reactor Auxiliary Cooling Systems (DRACS), to remove or mitigate the limitation on decay heat removal capability. DRACS has been widely used in SFR designs and in liquid salt cooled high temperature reactors. The containment cooling system in BWR is another example of volume based decay removal systems. DRACS composes of natural circulation loops with two sets of heat exchangers, one in reactor side and another is in environment side. DRACS has the benefits of increasing the power as needed (scalability) and modularity. This paper introduces the concept of using DRACS to enhance HTGRs passive safety and economy.

  2. Effect of Intake Air Filter Condition on Vehicle Fuel Economy

    SciTech Connect

    Norman, Kevin M; Huff, Shean P; West, Brian H

    2009-02-01

    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 fuel economy with increasing restriction. However, the level of restriction required to cause a substantial (10-15%) decrease in fuel economy (such as that cited in the literature) was so severe that the vehicle was almost undrivable. Acceleration performance on all vehicles was improved with a clean air filter. Once it was determined how severe the restriction had to be to affect the carbureted vehicle fuel economy, the 2007 Buick Lucerne was retested in a similar manner. We were not able to achieve the level of restriction that was achieved with the 1972 Pontiac with the Lucerne. The Lucerne's air filter box would not hold the filter in place under such severe conditions. (It is believed that this testing exceeded the design limits of the air box.) Tests were conducted at a lower restriction level (although still considerably more severe than the initial clogged filter testing), allowing the air filter to stay seated in the air box, and no significant change was observed in the Lucerne's fuel economy or the AFR over the HFET cycle. Closed-loop control in modern fuel injected vehicle applications is sophisticated enough to keep a clogged air filter from affecting the vehicle fuel economy. However for older, open-loop, carbureted vehicles, a clogged air filter can affect the fuel economy. For the vehicle tested, the fuel economy with a new air filter improved as much as 14% over that with a severely clogged filter (in which the filter was so clogged that drivability was impacted). Under a more typical state of clog, the improvement with a new filter ranged from 2 to 6%.

We find that the village funds have increased total short-term credit, consumption, agricultural investment, income growth (from business and labor), but decreased overall asset growth. We also find a positive impact on wages, an important general equilibrium effect. The findings are broadly consistent qualitatively with models of credit-constrained household behavior and models of intermediation and growth. PMID:22844546

    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.

  12. An empirical study of economies of scope in home healthcare.

    PubMed Central

    Gonzales, T I

    1997-01-01

    OBJECTIVE: To apply the economic theory of economies of scope to the home healthcare industry. DATA SOURCES: Data on 488 observations obtained from the Cost Report (HCFA Form 1728-86) of all Connecticut state-licensed, Medicare-certified home health agencies. STUDY DESIGN: The Cost Report was the primary source of data for this study. Information on total cost, scope, and other related factors was collected. Logarithmic and nonlinear regression analyses were used to identify factors related to scope and also to test for economies of scope. DATA COLLECTION METHOD: Data collected were both cross-sectional and time series (from 1988-1992). Data accuracy was verified using description of frequencies, measures of central tendency and variation, and a calculation package so that a computer calculation on the data could be compared with the agency's calculation. PRINCIPAL FINDINGS: It was determined that initially as scope increases, costs go down, thus proving economies of scope. For larger values of scope, it was determined that costs go up, proving diseconomies of scope. CONCLUSIONS: Many of the home health agencies included in this study provide more services than is cost effective given the economic theory of economies of scope. PMID:9240283

  13. 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 (), Laclau (), and Lockwood (). 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'.

    2009-01-01

    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

  15. Measuring flood footprint of a regional economy - A case study for the UK flooding

    Guan, D.

    2013-12-01

    Analysis of the urban economy and society is central to understanding the broad impacts of flooding and to identify cost-effective adaptation and mitigation measures. Assessments of the flooding impacts on cities have traditionally focused on the initial impact on people and assets. These initial estimates (so-called ';direct damage') are useful both in understanding the immediate implications of damage, and in marshalling the pools of capital and supplies required for re-building after an event. Since different economies as well as societies are coupled, especially under the current economic crisis, any small-scale damage may be multiplied and cascaded throughout wider economic systems and social networks. The direct and indirect damage is currently not evaluated well and could be captured by quantification of what we call the flood footprint. Flooding in one location can impact the whole UK economy. Neglecting these knock-on costs (i.e. the true footprint of the flood) means we might be ignoring the economic benefits and beneficiaries of flood risk management interventions. In 2007, for example, floods cost the economy about £3.2 bn directly, but the wider effect might actually add another 50% to 250% to that. Flood footprint is a measure of the exclusive total socioeconomic impact that is directly and indirectly caused by a flood event to the flooding region and wider economic systems and social networks. We adopt the UK 2012 flooding. An input-output basic dynamic inequalities (BDI) model is used to assess the impact of the floodings on the level of a Yorkshire economy, accounting for interactions between industries through demand and supply of intermediate consumption goods with a circular flow. After the disaster the economy will be unbalanced. The recovery process finishes when the economy is completely balance, i.e., when labour production capacity equals demands and production and all the variables reach pre-disaster levels. The analysis is carried out focusing on 42 sectors. Most regional data have been produced from the Multisectoral Dynamic Model of the UK economy. The flooding caused a 3.56% direct damage in the Yorkshire economy, while the indirect accounted for 14.58%.Utilities and transportation where the sectors that suffered the greatest direct impact. This impact indirectly transferred through business and supply chain to services, construction and primary industries.

    "The main objective of this paper is to evaluate the impact of the large remittances made by Egyptian migrants to their home country on the Egyptian economy. In order to study this impact, we use the implications of the standard Keynesian model. We estimated the structural equations of the model using annual data for the Egyptian economy over the period from 1970 to 1984.... The results suggest that remittances have had a strong positive impact on GNP in Egypt." The authors note that remittances especially affect private consumption spending. Policy implications concerning labor migration are discussed. (SUMMARY IN FRE AND SPA) PMID:12159603

  12. Domination and evolution in agent based model of an economy

    NASA Astrophysics Data System (ADS)

    Kazmi, Syed S.

    We introduce Agent Based Model of a pure exchange economy and a simple economy that includes production, consumption and distributions. Markets are described by Edgeworth Exchange in both models. Trades are binary bilateral trades at prices that are set in each trade. We found that the prices converge over time to a value that is not the standard Equilibrium value given by the Walrasian Tattonement fiction. The average price, and the distributions of Wealth, depends on the degree of Domination (persuasive power) we introduced based on differentials in trading "leverage" due to wealth differences. The full economy model is allowed to evolve by replacement of agents that do not survive with agents having random properties. We found that, depending upon the average productivity compared to the average consumption, very different kinds of behavior emerged. The Economy as a whole reaches a steady state by the population adapting to the conditions of productivity and consumption. Correlations develop in a population between what would be for each individual a random assignment of Productivity, Labor power, Wealth, and Preferences. The population adapts to the economic environment by development of these Correlations and without any learning process. We see signs of emerging social structure as a result of necessity of survival.

    2014-02-01

    In an 8-week period, there were 16 shootings with three fatalities, three stabbings, and 14 additional "aggravated assaults" in the four square blocks surrounding our field site in the Puerto Rican corner of North Philadelphia. In the aftermath of the shoot-outs, the drug sellers operating on our block were forced to close down their operations by several mothers who repeatedly called the police. Drawing on the concept of moral economy (Thompson, Scott, Taussig), Mauss's interpretation of gift exchange, and a political economy critique of hypercarceralization in the United States, we understand the high levels of US inner-city violence as operating within a moral logic framed by economic scarcity and hostile state relations. Residents seek security, self-respect, and profit in social networks that compel them to participate in solidary exchanges of assistive violence dynamized by kinship and gender obligations. A hierarchical, extractive drug economy fills the void left by deindustrialization, resulting in a dynamic of embodied primitive accumulation at the expense of addicted customers and chronically incarcerated just-in-time street sellers at high risk of assault. Nevertheless, the mobilization of violence organizing the illegal drug economy also follows ethical norms and obligations that are recognized as legitimate by many local residents. PMID:25067849

  18. Fuel economy of hybrid fuel-cell vehicles

    NASA Astrophysics Data System (ADS)

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

    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.

  19. Nuclides Economy

    Ivanov, Evgeny; Subbotin, Stanislav

    2007-07-01

    Traditionally the subject of discussion about the nuclear technology development is focused on the conditions that facilitate the nuclear power deployment. The main objective of this work is seeking of methodological basis for analysis of the coupling consequences of nuclear development. Nuclide economy is the term, which defines a new kind of society relations, dependent on nuclear technology development. It is rather closed to the setting of problems then to the solving of them. Last year Dr. Jonathan Tennenbaum published in Executive Intelligence Review Vol. 33 no 40 the article entitled as 'The Isotope Economy' where main interconnections for nuclear energy technologies and their infrastructure had been explained on the popular level. There he has given several answers and, therefore, just here we will try to expand this concept. We were interested by this publication because of similarity of our vision of resource base of technologies development. The main paradigm of 'Isotope economy' was expresses by Lyndon H. LaRouche: 'Instead of viewing the relevant resources of the planet as if they were a fixed totality, we must now assume responsibility of man's creating the new resources which will be more than adequate to sustain a growing world population at a constantly improved standard of physical per-capita output, and personal consumption'. We also consider the needed resources as a dynamic category. Nuclide economy and nuclide logistics both are needed for identifying of the future development of nuclear power as far we follow the holistic analysis approach 'from cave to grave'. Thus here we try to reasoning of decision making procedures and factors required for it in frame of innovative proposals development and deployment. The nuclear power development is needed in humanitarian scientific support with maximally deep consideration of all inter-disciplinary aspects of the nuclear power and nuclear technologies implementation. The main objectives for such consideration should be prognosis of all political, social, environmental and infra-structural consequences. Understanding of this necessity turned us to use the formalism of so called techno-dynamics and represent of resources needed for nuclear technology development as dynamic categories. The basic ideas of the methodology of innovative project assessment have been applied for holistic analysis of the development of the nuclear systems. This methodology has been developed for innovative proposals analysis in frame of IAEA INPRO project and it was a consensus product of the wide international expert's society discussions. All aspects of application of radioactivity in the industry and medicine had not been presented because the main ideas are quite evident but scale factor of their using has too big uncertainties. But cyclic character of organizing fuel management for the future development of nuclear technologies was added by cycles of structure materials as well. It has obtained that asymptotically the nuclear technology generates their specific compositions of structure materials. Thus wide scale using of the nuclear power will make new kind of metals that will be materials of nuclear quality. Development of new technologies and their penetration on the market will be accompanied by the several kinds of critical events. Crisis of resource's supplying is only most well known of them. But it is not both the single and not the most important. The model of corporation development made on Marshall's theory unambiguously demonstrates that transition from one technology to another can be made only in conditions of falling of the market. This result does not allow us to predict of time of the optimal transition from one technology basis onto the nets generation but it gives an indicator of readiness for changing of the mainstream. For the analysis of new innovative initiative it has been used the scale factor. Thus it shows that required installed capacity of G.N.E.P. systems will not be less then two hundred GW. Therefore the burner segment of the projected syste ms should also have significant capacity. Consequently it will lead to the flexible fuel cycle and to the keeping of the breeding options. Concept of nuclide economy gives understanding of real motivation that lied in the basis of one or other innovative proposals. By another words it is only tool for cross-disciplinary systematic study of innovative technologies. (authors)

  4. Underdeveloping Appalachia: Toward an environmental sociology of extractive economies

    NASA Astrophysics Data System (ADS)

    Wishart, William Ryan

    This dissertation uses mixed methods to examine the role of the coal industry in the reproduction of Central Appalachia as an internal periphery within the United States and the economic, ecological, and human inequalities this entails. It also analyzes the related political economy and power structure of coal in a national context. Particularly important for analysis of the region's underdevelopment are the class relations involved in unequal ecological exchange and the establishment of successive "modes of extraction." I employ a historical comparative analysis of Appalachia to evaluate Bunker's thesis that resource dependent peripheries often become locked into a "mode of extraction" (with aspects parallel to Marxist concepts of mode of production) triggering economic and ecological path dependencies leading to underdevelopment. This historical comparative analysis establishes the background for a closer examination of the political economy of the modern US coal industry. After sketching the changes in the structure of monopoly and competition in the coal industry I employ network analysis of the directorate interlocks of the top twenty coal firms in the US within the larger energy policy-planning network to examine their connections with key institutions of the policy formation network of think tanks and business groups. My findings show the importance of the capacities of fossil fuel fractions of the capitalist class in formulating energy policy around issues such as the 2009 climate legislation. As a contribution to the growing literature applying the concept of metabolism as link between contemporary and classical theory, I examine the conflict at Coal River Mountain from the vantage points of ecology, political economy, and human development in dialectical rotation. Utilizing Marx's method of successive abstractions, the mountain is presented as a nexus of metabolic rifts in the human relationship to the earth's natural systems and an impediment to genuine human development. Finally, I conclude with some implications of this analysis for building a critical environmental sociology of extractive economies. This dissertation includes previously published materials.

  5. Regional Analysis of the Japanese Economy Based on Bayesian Modeling

    NASA Astrophysics Data System (ADS)

    Noda, Hideo; Kyo, Koki

    This paper aims to develop an alternative framework for empirical analysis of regional economic growth. We apply our proposed method to analyzing the Total Factor Productivity (TFP) changes in regional economies and structural characteristics among the regions in Japan. Conventional approaches to empirical analysis of regional economic growth are insufficient for an appropriate description of the complicated behavior of TFP. Accordingly, we assume that TFP is a time-varying parameter and estimate it using a Bayesian method that employs a smoothness priors approach. Compared with conventional approaches, this application of the Bayesian method facilitates a more detailed and sophisticated analysis of TFP. A major finding of the analysis is a significant change in the TFP trends of the Japanese economy, beginning around the time of the first oil shock. Furthermore, our analytical results suggest a meaningful direction for government policies to promote economic growth in Japan.

  6. Economy class syndrome: still a recurrent complication of long journeys.

    Economy class syndrome is a rare but still unavoidable complication of long haul flights, particularly in patients who carry various intrinsic risk factors. The tendency to affect even asymptomatic young people and the greater risk to fragment and propagate to the pulmonary circulation are the main characteristics of deep vein thrombosis of long-flight travelers. We report the clinical history of eight patients admitted to intensive care unit for confirmed or highly suspected economy class syndrome. Seven of them developed the syndrome within 72 h from a long return flight, one suffered from pulmonary embolism after a 12-h car trip. Two out of eight patients died, one because of extremely severe hemodynamic impairment, the other as a consequence of multiple organ failure caused by a concomitant myocardial infarction. Deep vein thrombosis and pulmonary embolism represent one of the main medical problems of air travel and cause almost 20% of deaths in people with no medical history. Although economy class syndrome occurs mostly in elderly, even the healthy young population can be affected and, in fact, three out of eight patients of our series were under 50 years of age. All our patients but one carried a well recognized risk factor for deep vein thrombosis. Clinical symptoms of deep vein thrombosis can sometimes be aspecific and confusing, so that a certain proportion of post-travel deep vein thrombosis, evolving favorably and not giving rise to pulmonary embolism, might effectively remain undiagnosed. Economy class syndrome is still quite difficult to deal with and controversial in terms of preventive strategies. PMID:17496687

  7. Quantum Mechanics and the Principle of Least Radix Economy

    NASA Astrophysics Data System (ADS)

    Garcia-Morales, Vladimir

    2015-03-01

    A new variational method, the principle of least radix economy, is formulated. The mathematical and physical relevance of the radix economy, also called digit capacity, is established, showing how physical laws can be derived from this concept in a unified way. The principle reinterprets and generalizes the principle of least action yielding two classes of physical solutions: least action paths and quantum wavefunctions. A new physical foundation of the Hilbert space of quantum mechanics is then accomplished and it is used to derive the Schrödinger and Dirac equations and the breaking of the commutativity of spacetime geometry. The formulation provides an explanation of how determinism and random statistical behavior coexist in spacetime and a framework is developed that allows dynamical processes to be formulated in terms of chains of digits. These methods lead to a new (pre-geometrical) foundation for Lorentz transformations and special relativity. The Parker-Rhodes combinatorial hierarchy is encompassed within our approach and this leads to an estimate of the interaction strength of the electromagnetic and gravitational forces that agrees with the experimental values to an error of less than one thousandth. Finally, it is shown how the principle of least-radix economy naturally gives rise to Boltzmann's principle of classical statistical thermodynamics. A new expression for a general (path-dependent) nonequilibrium entropy is proposed satisfying the Second Law of Thermodynamics.

  10. Development of a more market-oriented economy in china.

    PubMed

    Chow, G C

    1987-01-16

    Before 1978 in China, the economic institutions for agriculture and industry operated essentially under a centrally planned system. The reasons for a change toward a more market-oriented economy and the key elements of economic reform are discussed. Today the major issues being deliberated by the leading economic officials include reform of the price system, the administrative structure of state-owned enterprises, the banking system and macroeconomic control mechanisms, and foreign trade and investment.

  14. Wealth condensation in a simple model of economy

    NASA Astrophysics Data System (ADS)

    Bouchaud, Jean-Philippe; Mézard, Marc

    2000-07-01

    We introduce a simple model of economy, where the time evolution is described by an equation capturing both exchange between individuals and random speculative trading, in such a way that the fundamental symmetry of the economy under an arbitrary change of monetary units is insured. We investigate a mean-field limit of this equation and show that the distribution of wealth is of the Pareto (power-law) type. The Pareto behaviour of the tails of this distribution appears to be robust for finite range models, as shown using both a mapping to the random ‘directed polymer’ problem, as well as numerical simulations. In this context, a phase transition between an economy dominated by a few individuals and a situation where the wealth is more evenly spread out, is found. An interesting outcome is that the distribution of wealth tends to be very broadly distributed when exchanges are limited, either in amplitude or topologically. Favouring exchanges (and, less surprisingly, increasing taxes) seems to be an efficient way to reduce inequalities.

  15. The Impact of Alzheimer's Disease on the Chinese Economy

    Keogh-Brown, Marcus R.; Jensen, Henning Tarp; Arrighi, H. Michael; Smith, Richard D.

    2015-01-01

    Background Recent increases in life expectancy may greatly expand future Alzheimer's Disease (AD) burdens. China's demographic profile, aging workforce and predicted increasing burden of AD-related care make its economy vulnerable to AD impacts. Previous economic estimates of AD predominantly focus on health system burdens and omit wider whole-economy effects, potentially underestimating the full economic benefit of effective treatment. Methods AD-related prevalence, morbidity and mortality for 2011–2050 were simulated and were, together with associated caregiver time and costs, imposed on a dynamic Computable General Equilibrium model of the Chinese economy. Both economic and non-economic outcomes were analyzed. Findings Simulated Chinese AD prevalence quadrupled during 2011–50 from 6–28 million. The cumulative discounted value of eliminating AD equates to China's 2012 GDP (US$8 trillion), and the annual predicted real value approaches US AD cost-of-illness (COI) estimates, exceeding US$1 trillion by 2050 (2011-prices). Lost labor contributes 62% of macroeconomic impacts. Only 10% derives from informal care, challenging previous COI-estimates of 56%. Interpretation Health and macroeconomic models predict an unfolding 2011–2050 Chinese AD epidemic with serious macroeconomic consequences. Significant investment in research and development (medical and non-medical) is warranted and international researchers and national authorities should therefore target development of effective AD treatment and prevention strategies.

    Serradell-Lopez, Enric; Cavaller, Victor

    The main objective of this paper is to provide greater understanding of the nature of secrecy in firms. It presents an effort to develop some links between management of the secrecy and its relationship with culture. Using measures from Hofstede's work, we have linked some dimensions of national culture with CIS 3 UE survey database. The results show that some attributes of the culture as Masculinity and Uncertainty Avoidance have impact on the tendency of the firms for not to patent and maintain secrecy of their innovations.

  2. Political economy of the energy-groundwater nexus in India: exploring issues and assessing policy options

    Shah, Tushaar; Giordano, Mark; Mukherji, Aditi

    2012-08-01

    Indian agriculture is trapped in a complex nexus of groundwater depletion and energy subsidies. This nexus is the product of past public policy choices that initially offered opportunities to India's small-holder-based irrigation economy but has now generated in its wake myriad economic, social, and environmental distortions. Conventional `getting-the-price-right' solutions to reduce these distortions have consistently been undermined by the invidious political economy that the nexus has created. The historical evolution of the nexus is outlined, the nature and scale of the distortions it has created are explored, and alternative approaches which Indian policy makers can use to limit, if not eliminate, the damaging impacts of the distortions, are analysed.

  3. Fuel Economy Improvement Potential of a Heavy Duty Truck using V2x Communication

    SciTech Connect

    LaClair, Tim J; Verma, Rajeev; Norris, Sarah; Cochran, Robert

    2014-01-01

    In this paper, we introduce an intelligent driver assistance system to reduce fuel consumption in heavy duty vehicles irrespective of the driving style of the driver. We specifically study the potential of V2I and V2V communications to reduce fuel consumption in heavy duty trucks. Most ITS communications today are oriented towards vehicle safety, with communications strategies and hardware that tend to focus on low latency. This has resulted in technologies emerging with a relatively limited range for the communications. For fuel economy, it is expected that most benefits will be derived with greater communications distances, at the scale of many hundred meters or several kilometers, due to the large inertia of heavy duty vehicles. It may therefore be necessary to employ different communications strategies for ITS applications aimed at fuel economy and other environmental benefits than what is used for safety applications in order to achieve the greatest benefits.

  5. Economy of flight at supersonic speeds

    NASA Technical Reports Server (NTRS)

    Jones, R. T.

    1976-01-01

    Prandtl's theory is used to determine the airflow over bodies and wings adapted to supersonic flight. By making use of these results, and by incorporating in them an allowance for the probable skin friction, some estimates of expected lift-drag ratios are made for various flight speeds with the best configuration. At each speed a slender body and wings having the best angle of sweepback are considered. For the range of supersonic speeds shown an airplane of normal density and loading would be required to operate at an altitude of the order of 60,000 feet. The limiting value of 1-1/2 times the speed of sound corresponds to a flight speed of 1000 miles per hour. At this speed about 1.5 miles per gallon of fuel are expected. It is interesting to note that this value corresponds to a value of more than 15 miles per gallon when the weight is reduced to correspond to that of an ordinary automobile.

  7. Economy in the feeding of infants.

    PubMed

    Lamm, E; Delaney, J; Dwyer, J T

    1977-02-01

    The food costs of various infant feeds were examined with focus on how these vary and the cost differences between different feeding patterns in the 1st year of life. The objectives were: 1) to compare prices for branded commercial milk-based products with other types of formulas and breast milk, and with each other according to source of supply, 2) to compare prices of different sources of Beikost (foods other than milk or formulas) used in feeding babies and how these vary by form (home made versus various types of commercially prepared products) and among brands, 3) to review total annual costs of 5 different hypothetical feeding patterns and actual patterns; and 4) to summarize factors other than price which may be significant in the economics and efficiency of infant feeding. National price survey data on a large number of commercial products from several companies producing food for infants were made available for this study. In addition, during June 1976 price surveys were conducted in several large supermarkets, small grocery stores, and drugstores in the Boston area to furnish information on local price differentials. The least expensive acceptable food for an infant was found to be a home made evaporated milk formula. While food costs were quite low, the formula must be prepared, and preparation time was slightly longer than it was with pre-mixed products. Whole milk was the most inexpensive milk-based feed but was undesirable for infant feeding, at least in the early months of life. On a moderate cost diet which supplies the extra nutrients required for lactation primarily from animal resources, lactation ranked in the middle from the standpoint of food cost. The various commercial milk-based feeds were nearly twice the cost of evaporated milk formulas. Concentrated formulas were least expensive, followed by powdered, with ready-to-feed products being the most expensive. Costs of breast feeding for a year ranged from $156 to $281, depending on the diet selected. On the basis of cost per day to meet the infants' needs, the type of product (evaporated milk versus commercial formula in various forms) is responsible for the largest difference in price with the type of packaging of the commercial product as the next most important. Although some savings can be realized on food costs by a changeover to home preparation techniques for Beikost, these savings appear to be much less than those achieved by wise choice of the types of Beikost, regardless of whether the home or commercially prepared foods are used. The proportion of the "baby eating dollar" that is spent for various foods shifts as the baby grows and is dependent on the type of food purchased. In the later months of the 1st year, choice of milk or milk-based feedings, type of commercially prepared or home prepared Beikost, and choice of table foods become most important in determining the overall costs of the infant's diet. The fact that commercial formulas are provided at very low or no cost is probably primary in determining which types and forms of formula hospital services feed infants. Food waste, convenience, cultural acceptability, and cleaning time are among the factors involved in considerations of the best ways to feed infants. PMID:322067

  8. The political economy of capitated managed care.

    PubMed

    Emery, D W; Fawson, C; Herzberg, R Q

    1997-03-01

    Despite the fact that billions of dollars are being invested in capitated managed care, it has yet to be subjected to the rigors of robust microeconomic modeling; hence, the seemingly intuitive assumptions driving managed care orthodoxy continue to gain acceptance with almost no theoretical examination or debate. The research in this paper finds the standard unidimensional model of risk generally used to analyze capitation--i.e., that risk is homogenous in nature, organizationally fungible, and linear in amplitude--to be inadequate. Therefore, the paper proposes to introduce a multidimensional model based on the assumption that phenomenologically unrelated species of risk result from non-homogenous types of socioeconomic activity in the medical marketplace. The multidimensional analysis proceeds to concentrate on two species of risk: probability risk and technical risk. A two-dimensional risk matrix reveals that capitation, far from being a market-oriented solution, actually prevents the formation of a dynamic price system necessary to optimize marketplace trades of medical goods and services. The analysis concludes that a universal attempt to purchase healthcare through capitation or any other insurance mechanism would render the reasonable attainment of social efficiency highly problematic. While in reality there are other identifiable species of risk (such as cost-utility risk), the analysis proceeds to hypothesize what a market-oriented managed care approach might look like within a two-dimensional risk matrix.

    Trypanosomiasis, both of humans and of livestock, is one of the most important factors restricting economic development in Africa today. The present paper outlines how this disease is limiting agricultural, veterinary and forestry development in the Sudan, Bechuanaland and West Africa. The present tsetse-fly distribution is reviewed. Glossina palpalis and G. morsitans occur in the south Sudan and G. morsitans in the Ngamiland district of Bechuanaland; G. morsitans, G. palpalis and G. tachinoides are the most important species in West Africa. These tsetse flies have altered the cattle distribution in all three regions and, in addition to causing widespread disease, have created local overstocking problems in the tsetse-free grazing areas, and have enforced nomadism on breeding herds and economic loss in slaughter cattle along the trade cattle routes in West Africa. Human trypanosomiasis is not now such an urgent problem and public health measures have led to its control in all three areas. Increased agricultural development, which can be a successful and economic method of reclaiming land from tsetse flies, must be intensified in all three areas. Forest conservation policy comes into conflict with tsetse control measures only in West Africa. Detailed tsetse-fly surveys and research, on which future plans can be firmly based, are now urgently required. ImagesFIG. 6 PMID:14001093

    1994-12-31

    The author examines the economic component of domestic liberalization in different regional contexts in order to get closer to identifying an important engine of regime creation. In particular, ruling coalitions pursuing economic liberalization seem more likely to embrace regional nuclear regimes than their inward-looking, nationalist, and radical-confessional counterparts. The author suggests an alternate interpretation for why different states choose different portfolios to cope with their respective security concerns. The emphasis is more on explaining a favorable disposition to enter regime-like arrangements in nuclear matters than on listing incentives to procure nuclear weapons. The argument is relevant only to would-be or second-tier nuclear powers.

    Fuel economy potentials were calculated and compared among ten turbomachinery configurations. All gas turbine engines were evaluated with a continuously variable transmission in a 1978 compact car. A reference fuel economy was calculated for the car with its conventional spark ignition piston engine and three speed automatic transmission. 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.

    The United States is not only the world's largest economy, but it is also one of the world's largest consumers of natural resources. The country, which is inhabited by some 5% of the world's population, uses roughly one-fifth of the global primary energy supply and 15% of all extracted materials. This article explores long-term trends and patterns of material use in the United States. Based on a material flow account (MFA) that is fully consistent with current standards of economy-wide MFAs and covers domestic extraction, imports, and exports of materials for a 135-year period, we investigated the evolution of the U.S. industrial metabolism. This process was characterized by an 18-fold increase in material consumption, a multiplication of material use per capita, and a shift from renewable biomass toward mineral and fossil resources. In spite of considerable improvements in material intensity, no dematerialization has happened so far; in contrast to other high-income countries, material use has not stabilized since the 1970s, but has continued to grow. This article compares patterns and trends of material use in the United States with those in Japan and the United Kingdom and discusses the factors underlying the disproportionately high level of U.S. per capita resource consumption.

    2009-12-01

    What implications might synthetic biology's potential as a wholly new method of production have for the world economy, particularly developing countries? Theories of political economy predict that synthetic biology can shift terms of trade and displace producers in developing countries. Governments, however, retain the ability to mitigate negative changes through social safety nets and to foster adaptation to some changes through research, education and investment. We consider the effects the synthetic production of otherwise naturally derived molecules are likely to have on trade and investment, particularly in developing countries. Both rubber in Malaysia and indigo dyes in India provide historical examples of natural molecules that faced market dislocations from synthetic competitors. Natural rubber was able to maintain significant market share, while natural indigo vanished from world markets. These cases demonstrate the two extremes of the impact synthetic biology might have on naturally derived products. If developing countries can cushion the pain of technological changes by providing producers support as they retool or exit, the harmful effects of synthetic biology can be mitigated while its benefits can still be captured.

    Emerging economies by definition tend to be less dependent on expatriate skills and labour than lower-income countries, yet remuneration (pay plus benefits) differences between expatriate and local workers persist in them to some degree. According to relative deprivation theory, economic development paradoxically elevates the salience of relatively small gaps in remuneration. We therefore expected workers to report injustice and demotivation regarding relative remuneration, despite the closing of remuneration gaps between expatriate and local workers due to the economic development of recent years. To explore that possibility, 482 skilled professionals from a variety of sectors and organizations in two emerging economies, India (n = 233, response rate = 54%) and China (n = 249, response rate = 58%), participated in the research. International salaries were greater than local salaries by a factor of 2.73:1 in India and 1.90:1 in China; these mean ratios bordered on intolerable in the India sample and were largely tolerable among the sample from China. In both countries, differently remunerated workers differed in their justice cognitions and their demotivation, with lowered motivation and fewer justice cognitions in the locally salaried, local workers. These differences were however more statistically significant between people working in India than in China. Insofar as the motivational and justice gaps persisted, the findings support relative deprivation theory. Insofar as the same gaps appear to be sharper in the country with the higher-not lower-mean remuneration differential, they do not. An in-country workshop with local experts who interpreted the findings (in India), and content analysis of the participants' recommendations (in China) jointly recommended linking remuneration to (i) workplace performance instead of (ii) economy-of-origin, to help promote (iii) fairness.

    Studies of food remains from the Preceramic monumental site of E1 Paraíso, Peru (1800 to 1500 B.C.), have shed new light on a debate regarding the relative importance of seafood versus terrestrial resources and the role of cultigens in subsistence economies during the early development of Peruvian civilization. Fish was the primary animal food at the site whereas plant foods consisted of a mixture of cultivated resources (squashes, beans, peppers, and jicama) with an additional reliance on fruits (guava, lucuma, and pacae). Wild plants, especially the roots of sedges and cat-tail, also may have accounted for a substantial part of the diet. Cotton was a chief crop, used in making fishing tackle and the textiles that served as clothing and items of high value and status. As an example of the beginnings of civilization, El Paraíso is a case in which impressive architecture was built on a relatively simple subsistence economy and energy was expended in the production of resources useful in local and regional exchange systems.

    The aim of this paper is to present an efficient tool for evaluating the economy part of the sustainability of pig farming systems. The selected tool IDEA was tested on a sample of farms from 15 contrasted systems in Europe. A statistical analysis was carried out to check the capacity of the indicators to illustrate the variability of the population and to analyze which of these indicators contributed the most towards it. The scores obtained for the farms were consistent with the reality of pig production; the variable distribution showed an important variability of the sample. The principal component analysis and cluster analysis separated the sample into five subgroups, in which the six main indicators significantly differed, which underlines the robustness of the tool. The IDEA method was proven to be easily comprehensible, requiring few initial variables and with an efficient benchmarking system; all six indicators contributed to fully describe a varied and contrasted population.

    This study examined the performance effects of information asymmetry and economies of scope in diversified service firms. Tests using both accounting- and stock-market-based measures of performance revealed that information asymmetry improved performance more than economies of scope. As hypothesized, the benefits of information asymmetry were greater for firms offering services whose quality cannot be determined until after their purchase (experience services), and the benefits of economies of scope were greater for firms offering services whose quality can be determined prior to purchase (search services). However, without considering the interactive effects of service characteristics, economies of scope were negatively associated with performance for diversified service firms overall. PMID:10123744

    An investigation was conducted on a full-scale air-cooled cylinder in order to establish an effective means of maintaining maximum-economy spark timing with varying engine operating conditions. Variable fuel-air-ratio runs were conducted in which relations were determined between the spark travel, and cylinder-pressure rise. An instrument for controlling spark timing was developed that automatically maintained maximum-economy spark timing with varying engine operating conditions. The instrument also indicated the occurrence of preignition.

  16. The political economy of oil and the Niger Delta crisis

    NASA Astrophysics Data System (ADS)

    Ighodaro, Osaro O.

    This study is about the burgeoning crisis in Nigeria's Oil Producing Niger Delta region. Discerning the intersecting contributive factors to the crisis, this dissertation suggests that the Niger Delta crisis is symptomatic of challenges to development in Nigeria. Due to the insidious colonial/neo-colonial practices of subjugation, and exploitation of the host communities, it is suggested that the extractive, super-profit motive of Shell, the concomitant environmental degradation, corruption of a bellicose state, ethnic conflict and suffering of the masses are outcomes of a long historically debilitating relationship with international capital which causes irreparable retardation to the host communities. From cash crop economy to a mono-oil economy resources are removed from the communities and used to enhance the colonial state and their post-colonial harbingers of misery. Hence, the indigenous people claim that the Niger Delta is in a crisis, and they are willing to confront the triple alliance of multinational oil companies like Shell, the Nigerian State and the local elite so long as these allies of subjugation continue to neglect the goose that lays the proverbial golden egg (oil that is). Theoretically, a hybrid Political Economy approach was adopted as the over-aching framework for the study, while Dependency theory, modified by what I have called African Transformative scholarly perspective, served as the conceptual tool. Primary and secondary sources of data, including personal observation, interviews, official government documents and other publications were utilized for this analysis. In view of recommendations, it is suggested that first, the Nigerian state should assume decisive and unflinching leadership in holding oil companies responsible for their activities in the host communities; second, oil companies (like Shell) should see themselves as an integral part of the host communities; invest in their development by providing employment opportunities and adhering to humane environmental practices. Finally, I suggest that the ownership and control of all resources, including oil should be vested in those communities in which they are found. The revenues accruing to the constitutive states of Nigeria will be accordingly taxed with the revenues from the taxes utilized for the general good of the polity especially the less endowed communities.

    In a world of finite resources and ecosystem capacity, the prevailing model of economic growth, founded on ever-increasing consumption of resources and emission pollutants, cannot be sustained any longer. In this context, the "green economy" concept has offered the opportunity to change the way that society manages the interaction of the environmental and economic domains. To enable society to build and sustain a green economy, the associated concept of "green nanotechnology" aims to exploit nano-innovations in materials science and engineering to generate products and processes that are energy efficient as well as economically and environmentally sustainable. These applications are expected to impact a large range of economic sectors, such as energy production and storage, clean up-technologies, as well as construction and related infrastructure industries. These solutions may offer the opportunities to reduce pressure on raw materials trading on renewable energy, to improve power delivery systems to be more reliable, efficient and safe as well as to use unconventional water sources or nano-enabled construction products therefore providing better ecosystem and livelihood conditions.However, the benefits of incorporating nanomaterials in green products and processes may bring challenges with them for environmental, health and safety risks, ethical and social issues, as well as uncertainty concerning market and consumer acceptance. Therefore, our aim is to examine the relationships among guiding principles for a green economy and opportunities for introducing nano-applications in this field as well as to critically analyze their practical challenges, especially related to the impact that they may have on the health and safety of workers involved in this innovative sector. These are principally due to the not fully known nanomaterial hazardous properties, as well as to the difficulties in characterizing exposure and defining emerging risks for the workforce. Interestingly, this review proposes action strategies for the assessment, management and communication of risks aimed to precautionary adopt preventive measures including formation and training of employees, collective and personal protective equipment, health surveillance programs to protect the health and safety of nano-workers. It finally underlines the importance that occupational health considerations will have on achieving an effectively sustainable development of nanotechnology. PMID:25294341

  19. Running for Exercise Mitigates Age-Related Deterioration of Walking Economy

    Introduction Impaired walking performance is a key predictor of morbidity among older adults. A distinctive characteristic of impaired walking performance among older adults is a greater metabolic cost (worse economy) compared to young adults. However, older adults who consistently run have been shown to retain a similar running economy as young runners. Unfortunately, those running studies did not measure the metabolic cost of walking. Thus, it is unclear if running exercise can prevent the deterioration of walking economy. Purpose To determine if and how regular walking vs. running exercise affects the economy of locomotion in older adults. Methods 15 older adults (69±3 years) who walk ?30 min, 3x/week for exercise, “walkers” and 15 older adults (69±5 years) who run ?30 min, 3x/week, “runners” walked on a force-instrumented treadmill at three speeds (0.75, 1.25, and 1.75 m/s). We determined walking economy using expired gas analysis and walking mechanics via ground reaction forces during the last 2 minutes of each 5 minute trial. We compared walking economy between the two groups and to non-aerobically trained young and older adults from a prior study. Results Older runners had a 7–10% better walking economy than older walkers over the range of speeds tested (p?=?.016) and had walking economy similar to young sedentary adults over a similar range of speeds (p?=?.237). We found no substantial biomechanical differences between older walkers and runners. In contrast to older runners, older walkers had similar walking economy as older sedentary adults (p?=?.461) and ?26% worse walking economy than young adults (p<.0001). Conclusion Running mitigates the age-related deterioration of walking economy whereas walking for exercise appears to have minimal effect on the age-related deterioration in walking economy.

    This paper draws on stem cell research and financial derivatives as two case studies to analyse the role of scientific knowledge and technology in the development of the Chinese knowledge economy. The findings suggest that, despite China's recent commitments in acquiring international expertise, there is a decoupling between knowledge acquisitions and applications in the institutionalisation of knowledge within these sectors. Scientific-based knowledge and professional know-how are on the one hand perceived as prime drivers of China's development, yet they on the other hand remain subordinate to existing administrative infrastructures. The paper further elucidates the causes and implications of this by describing the dual reality of knowledge in relation to an isomorphic process of rationalisation outlined by new institutional organisational theory.

    Vehicle air-conditioning can significantly impact fuel economy and tailpipe emissions of conventional and hybrid electric vehicles and reduce electric vehicle range. In addition, a new US emissions procedure, called the Supplemental Federal Test Procedure, has provided the motivation for reducing the size of vehicle air-conditioning systems in the US. The SFTP will measure tailpipe emissions with the air-conditioning system operating. Current air-conditioning systems can reduce the fuel economy of high fuel-economy vehicles by about 50% and reduce the fuel economy of today's mid-sized vehicles by more than 20% while increasing NOx by nearly 80% and CO by 70%.

    A fear of crashes preoccupies stock market observers, both investors and economic decision makers (governments, banks). This is reflected in major efforts to predict future stock values. However, an economic system under prolonged stress may have in its nature to plunge to lower performance levels but recover without suffering damage. To support this claim, we draw parallels between two complex systems: that of the heart, as observed through the rate of heartbeat, and the economy, measured by the stock index record. The ultimate stress situation of fetal heartbeat during labour provides a conceptual basis for accommodating heavy crashes. It also suggests a different perspective for evaluating crashes and post crash recovery in order to diagnose, and (ultimately) prognose, ‘economic health’, in addition to monitoring the stock index value.

  6. The dawn of the e-lance economy.

    PubMed

    Malone, T W; Laubacher, R J

    1998-01-01

    Will the large industrial corporation dominate the twenty-first century as it did the twentieth? Maybe not. Drawing on their research at MIT's Initiative on Inventing the Organizations of the 21st Century, Thomas Malone and Robert Laubacher postulate a world in which business is not controlled through a stable chain of management in a large, permanent company. Rather, it is carried out autonomously by independent contractors connected through personal computers and electronic networks. These electronically connected free-lancers-e-lancers-would join together into fluid and temporary networks to produce and sell goods and services. When the job is done--after a day, a month, a year--the network would dissolve and its members would again become independent agents. Far from being a wild hypothesis, the e-lance economy is, in many ways, already upon us. We see it in the rise of outsourcing and telecommuting, in the increasing importance within corporations of ad-hoc project teams, and in the evolution of the Internet. Most of the necessary building blocks of this type of business organization--efficient networks, data interchange standards, groupware, electronic currency, venture capital micromarkets--are either in place or under development. What is lagging behind is our imagination. But, the authors contend, it is important to consider sooner rather than later the profound implications of how such an e-lance economy might work. They examine the opportunities, and the problems, that may arise and anticipate how the role of managers may change fundamentally--or possibly even disappear altogether. PMID:10185429

    1978-01-01

    Improvements in fuel economy for a broad spectrum of truck engines and waste heat utilization concepts are evaluated and compared. The engines considered are the diesel, spark ignition, gas turbine, and Stirling. The waste heat utilization concepts include preheating, regeneration, turbocharging, turbocompounding, and Rankine engine compounding. Predictions were based on fuel-air cycle analyses, computer simulation, and engine test data. The results reveal that diesel driving cycle performance can be increased by 20% through increased turbocharging, turbocompounding, and Rankine engine compounding. The Rankine engine compounding provides about three times as much improvement as turbocompounding but also costs about three times as much. Performance for either is approximately doubled if applied to an adiabatic diesel.

    An investigation was conducted to determine the effect of a coolant solution of 25 percent ethyl alcohol, 25 percent methyl alcohol, and 50 percent water by volume and maximum-economy spark advance on knock-limited performance and fuel economy of a large air-cooled cylinder. The knock-limited performance of the cylinder at engine speeds of 2100 and 2500 rpm was determined for coolant-fuel ratios of 0.0, 0.2, and 0.4. The effect of water-alcohol injection on fuel economy was determined in constant charge-air flow tests. The tests were conducted at a spark advance of 20 deg B.T.C. and maximum-economy spark advance.

  10. On Steady Distributions of Kinetic Models of Conservative Economies

    Matthes, Daniel; Toscani, Giuseppe

    2008-03-01

    We analyze the large-time behavior of various kinetic models for the redistribution of wealth in simple market economies introduced in the pertinent literature in recent years. As specific examples, we study models with fixed saving propensity introduced by Chakraborti and Chakrabarti (Eur. Phys. J. B 17:167-170, 2000), as well as models involving both exchange between agents and speculative trading as considered by Cordier et al. (J. Stat. Phys. 120:253-277, 2005) We derive a sufficient criterion under which a unique non-trivial stationary state exists, and provide criteria under which these steady states do or do not possess a Pareto tail. In particular, we prove the absence of Pareto tails in pointwise conservative models, like the one in (Eur. Phys. J. B 17:167-170, 2000), while models with speculative trades introduced in (J. Stat. Phys. 120:253-277, 2005) develop fat tails if the market is "risky enough". The results are derived by a Fourier-based technique first developed for the Maxwell-Boltzmann equation (Gabetta et al. in J. Stat. Phys. 81:901-934, 1995; Bisi et al. in J. Stat. Phys. 118(1-2):301-331, 2005; Pareschi and Toscani in J. Stat. Phys. 124(2-4):747-779, 2006) and from a recursive relation which allows to calculate arbitrary moments of the stationary state.

    Objective: Robotic assistance during surgery has been shown to be a useful resource to both augment the surgical skills of the surgeon through tele-operation, and to assist the surgeon handling the surgical instruments to the surgeon, similar to a surgical tech. We evaluated the performance and effect of a gesture driven surgical robotic nurse in the context of economy of movements, during an abdominal incision and closure exercise with a simulator. Methods: A longitudinal midline incision (100 mm) was performed on the simulated abdominal wall to enter the peritoneal cavity without damaging the internal organs. The wound was then closed using a blunt needle ensuring that no tissue is caught up by the suture material. All the instruments required to complete this task were delivered by a robotic surgical manipulator directly to the surgeon. The instruments were requested through voice and gesture recognition. The robotic system used a low end range sensor camera to extract the hand poses and for recognizing the gestures. The instruments were delivered to the vicinity of the patient, at chest height and at a reachable distance to the surgeon. Task performance measures for each of three abdominal incision and closure exercises were measured and compared to a human scrub nurse instrument delivery action. Picking instrument position variance, completion time and trajectory of the hand were recorded for further analysis. Results: The variance of the position of the robotic tip when delivering the surgical instrument is compared to the same position when a human delivers the instrument. The variance was found to be 88.86% smaller compared to the human delivery group. The mean task completion time to complete the surgical exercise was 162.7+/- 10.1 secs for the human assistant and 191.6+/- 3.3 secs (P<.01) when using the robotic standard display group. Conclusion: Multimodal robotic scrub nurse assistant improves the surgical procedure by reducing the number of movements (lower variance in the picking position). The variance of the picking point is closely related to the concept of economy of movements in the operating room. Improving the effectiveness of the operating room can potentially enhance the safety of surgical interventions without affecting the performance time.

  12. Growing a market economy

    Basu, N.; Pryor, R.J.

    1997-09-01

    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.

  14. Role of sugar cane in Brazil's history and economy

    SciTech Connect

    Nastari, P.M.

    1983-01-01

    The history and evolution of the sugar-cane culture in Brazil is reviewed. An econometric model is constructed to explain the economic relationships of supply and demand of sugar, hydrous ethanol (ethyl alcohol), and anhydrous ethanol in Brazil overtime. Estimates of the parameters in the model are obtained using the methods of ordinary least squares and three stages least squares. Because the number of exogenous variables is larger than the number of observations, principal components of the exogenous variables is used. The model estimated using three stages least squares with seven principal components has the best performance among the alternatives considered. Using the estimated model, the level of a number of policy variables is determined in consistency with the objectives of ethanol production established by the Brazilian government for 1985. It is estimated that in 1985 the proportion of anhydrous ethanol added to gasoline must be 16.5%. Analysis of the net income accrued by producers and the government since the creation of the National Alcohol Program (Proalcool) in 1975 reveals that producers of sugar have been able to triple their net annual income. Independent producers of ethanol have also been able to accrue positive net results during this period. It is concluded that the Proalcool has been beneficial to the Brazilian economy, largely because of the savings in oil imports and the internal creation of jobs, while at the same time it has contributed to a superavit in the government's budget.

    Online traces of human activity offer novel opportunities to study the dynamics of complex knowledge exchange networks, in particular how emergent patterns of collective attention determine what new information is generated and consumed. Can we measure the relationship between demand and supply for new information about a topic? We propose a normalization method to compare attention bursts statistics across topics with heterogeneous distribution of attention. Through analysis of a massive dataset on traffic to Wikipedia, we find that the production of new knowledge is associated to significant shifts of collective attention, which we take as proxy for its demand. This is consistent with a scenario in which allocation of attention toward a topic stimulates the demand for information about it, and in turn the supply of further novel information. However, attention spikes only for a limited time span, during which new content has higher chances of receiving traffic, compared to content created later or earlier on. Our attempt to quantify demand and supply of information, and our finding about their temporal ordering, may lead to the development of the fundamental laws of the attention economy, and to a better understanding of social exchange of knowledge information networks.

  16. The political economy of sexism in industrial health.

    PubMed

    Felker, M

    1982-01-01

    In the last several years, increasing numbers of American women have lost their industrial jobs or have been refused jobs because they are of child-bearing age. Industrial physicians and management in manufacturing plants using various chemicals have decided that the risk their women workers take of having deformed children as a result of workplace hazards is such that the women must be 'protected'. An alternative 'choice' given to many of these women is proof of sterilization in order to maintain or attain jobs. In choosing to approach the growing problem of workplace contamination in this fashion, management and industrial physicians ignore the effects of chemical toxins on male employees' reproductive systems, and obscure the larger problem of hazards to all employees' total body systems. This paper explores the political economy of the interactions between Society, the Medical System and Women in a Capitalist State, in order to uncover the flow of forces operating in this conflict. Using an historical perspective, a feminist analysis is made of the social order, and a model is presented which demonstrates the articulations between the domains mentioned above, particularly the historical control by the medical system as an agent of the state.

    PubMed

    Höhler, Sabine

    2014-03-01

    This paper explores the relations between economy and ecology in the last quarter of the 20th century with the example of biodiversity. From its definition in the 1980s, the concept of biodiversity responded not only to conservational concerns but also to hopes and demands of economic profitability. The paper argues that archival systems of inventorying and surveying nature, the biodiversity database and the biodiversity portfolio, changed the view on nature from a resource to an investment. The paper studies the alliances of ecologists and environmental economists in managing nature according to economic principles of successful asset management, "diversification", with the aim to distribute risk, minimize ecological loss and maximize overall ecosystem performance. Finally, the paper discusses the assumptions and the consequences of transferring principles from financial risk management to landscape management. How has the substitution of the existential values of nature by shareholder value affected the relations between ecology, environment, and ecosystem conservation? Who gains and who looses in exchanging natural capital and financial capital, yields, and profits? PMID:24988757

    1987-01-01

    On-road fuel economy, given the variety of customer driving experiences, tends to be lower than that obtained under controlled laboratory conditions. Since the 1978 model year, Ford Motor Company (Ford) has been collecting and analyzing on-road fuel economy data from Ford vehicles leased to company employees for evaluation purposes. Based on data collected during the summer months, 1985-86 model passenger car on-road fuel economy was approximately 47% greater than that obtained with 1978 models. Also, on-road results continue to parallel laboratory values, remaining approximately 15% below the metro/highway value. City and highway fuel economy values are contained on a label affixed to all new cars. In 1985, the label values were adjusted to better represent the on-road customer fuel economy. An analysis of actual on-road results compared to the label values demonstrates that the adjustment factors are accomplishing the intended purpose.

  20. Clinical bioethics in china: the challenge of entering a market economy.

    PubMed

    Chen, Xiao-Yang

    2006-02-01

    Over the last quarter-century, China has experienced dramatic changes associated with its development of a market economy. The character of clinical practice is also profoundly influenced by the ways in which reimbursement scales are established in public hospitals. The market distortions that lead to the over-prescription of drugs and the medically unindicated use of more expensive drugs and more costly high-technology diagnostic and therapeutic interventions create the most significant threat to patients. The payment of red packets represents a black-market attempt to circumvent the non-market constraint on physicians' fees for services. These economic and practice pattern changes are taking place as China and many Pacific Rim societies are reconsidering the moral foundations of their professional ethics and their bioethics. The integrity of the medical profession and the trust of patients in physicians can only be restored and protected if the distorting forces of contemporary public policy are altered. PMID:16464767

    The purpose was to investigate how a negative life event (NLE) affects perceived psychosocial stress, recovery and running economy (RE). Competitive runners were monitored in a prospective non-experimental cohort study over one full training season in which they experienced the same unplanned severe NLE. 16 runners recorded stress and recovery scores (RESTQ-Sport) every week. The average scores over 3 weeks before the NLE were used as a baseline and were compared to scores during the week of the NLE (week 0), week 1 and week 2. 7 runners completed a submaximal treadmill test before and after the NLE. Repeated measures ANOVAs revealed that most scores on general stress scales were increased in week 0 and 1. Of the general recovery scales, "general well-being" was decreased in week 0 and 1, "social" and "physical recovery" were decreased in week 0. No changes in the sport-specific stress scales were found. However, 2 of the sport-specific recovery scales were decreased in week 0. An impaired RE was shown 3 weeks after the NLE. Therefore, it is important to know what is going on in an athlete's life, because stressful life events alter RE after the stress and recovery already returned to normal levels. PMID:26669252

    Genetic circuits in living cells share transcriptional and translational resources that are available in limited amounts. This leads to unexpected couplings among seemingly unconnected modules, which result in poorly predictable circuit behavior. In this study, we determine these interdependencies between products of different genes by characterizing the economy of how transcriptional and translational resources are allocated to the production of proteins in genetic circuits. We discover that, when expressed from the same plasmid, the combinations of attainable protein concentrations are constrained by a linear relationship, which can be interpreted as an isocost line, a concept used in microeconomics. We created a library of circuits with two reporter genes, one constitutive and the other inducible in the same plasmid, without a regulatory path between them. In agreement with the model predictions, experiments reveal that the isocost line rotates when changing the ribosome binding site strength of the inducible gene and shifts when modifying the plasmid copy number. These results demonstrate that isocost lines can be employed to predict how genetic circuits become coupled when sharing resources and provide design guidelines for minimizing the effects of such couplings.

    This paper discusses a significant illicit economy, including black and grey aspects, associated with medical waste scavenging and recycling in a megacity, considering hazards to the specific group involved in scavenging as well as hazards to the general population of city dwellers. Data were collected in Dhaka, Bangladesh, using a variety of techniques based on formal representative sampling for fixed populations (such as recycling operatives) and adaptive sampling for roaming populations (such as scavengers). Extremely hazardous items (including date expired medicines, used syringes, knives, blades and saline bags) were scavenged, repackaged and resold to the community. Some HCE employees were also observed to sell hazardous items directly to scavengers, and both employees and scavengers were observed to supply contaminated items to an informal plastics recycling industry. This trade was made possible by the absence of segregation, secure storage and proper disposal of medical waste. Corruption, a lack of accountability and individual responsibility were also found to be contributors. In most cases the individuals involved with these activities did not understand the risks. Although motivation was often for personal gain or in support of substance abuse, participants sometimes felt that they were providing a useful service to the community. PMID:21820235

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

    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.

    The aim of this paper is to examine the relationship between the mass production of furniture in modern industrial societies and lower back pain (LBP). The latter has proven to be a major cost to health services and private industry throughout the industrialised world and now represents a global health issue as recent WHO reports on obesity and LBP reveal. Thus far there have been few co-ordinated attempts to deal with the causes of the problem through public policy. Drawing upon a range of sources in anthropology, health studies, politics and economics, the paper argues that this a modern social problem rooted in the contingent conjuncture of natural and social causal mechanisms. The key question it raises is: what are the appropriate mechanisms for addressing this problem? This paper develops an analysis rooted in libertarian social theory and argues that both the state and the capitalist market are flawed mechanisms for resolving this problem. There remains a fundamental dilemma for libertarians, however. Whilst the state and the market may well be flawed mechanisms, they are the dominant ones shaping global political economy. To what extent can libertarians work within these structures and remain committed to libertarian goals? PMID:19170972

    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.

    The Internet-led digital economy is changing both the production and consumption patterns at the global scale. Although great potential exists to harness information technology in general and the Internet in particular and improve the environment, possible negative impacts of e-commerce on the environment should also be considered and dealt with. In this forum, we discuss both the potential positive and negative impacts of e-commerce. Drawing from insights gained from the complexity theory, we also delineate some broad contours for environmental policies in the information age. Given the paradoxical nature of technological innovations, we want to caution the scientific community and policymakers not to treat the Internet as the Holy Grail for environmental salvation.

    2015-04-01

    The relationship between poverty and mental health is indisputable. However, to have an influence on the next set of sustainable global development goals, we need to understand the causal relationships between social determinants such as poverty, inequality, lack of education and unemployment; thereby clarifying which aspects of poverty are the key drivers of mental illness. Some of the major challenges identified by Lund (2014) in understanding the poverty-mental health relationship are discussed including: the need for appropriate poverty indicators; extending this research agenda to a broader range of mental health outcomes; the need to engage with theoretical concepts such as Amartya Sen's capability framework; and the need to integrate the concept of income/economic inequality into studies of poverty and mental health. Although income inequality is a powerful driver of poor physical and mental health outcomes, it features rarely in research and discourse on social determinants of mental health. This paper interrogates in detail the relationships between poverty, income inequality and mental health, specifically: the role of income inequality as a mediator of the poverty-mental health relationship; the relative utility of commonly used income inequality metrics; and the likely mechanisms underlying the impact of inequality on mental health, including direct stress due to the setting up of social comparisons as well as the erosion of social capital leading to social fragmentation. Finally, we need to interrogate the upstream political, social and economic causes of inequality itself, since these should also become potential targets in efforts to promote sustainable development goals and improve population (mental) health. In particular, neoliberal (market-oriented) political doctrines lead to both increased income inequality and reduced social cohesion. In conclusion, understanding the relationships between politics, poverty, inequality and mental health outcomes requires us to develop a robust, evidence-based 'political economy of mental health.'

    Hale, A

    1996-10-01

    This article discusses the lack of input from women in international debates about the global economy. Women in the South are the most vulnerable to exploitation and most ignored in international discussions of how to protect fair labor standards. Restructuring has led to loss of secure jobs in the public sector and the expansion of female employment in low-paid, insecure, unskilled jobs. Businesses desire a cheap and flexible workforce. Declines in social services, the elimination of subsidies on basic goods, and the introduction of user fees puts pressure on women to supplement family income. A parallel outcome is reduced employment rights, neglect of health and safety standards, and increased disregard among women for their domestic responsibilities. There is a need for alternative models of development. The Self-Employed Women's Organization in India serves as a model for resisting exploitation among self-employed and home-based employees. Female industrial strikers are demanding attention to excessive hours of work, enforced overtime, bullying, and lack of sanitary and medical facilities. There is always fear that organized resistance will lead to industrial relocation or loss of jobs. The International Labor Organization has had a code for 20 years, but the threat of exposure to the press is sometimes more effective. There must be regulation throughout subcontracting chains of transnational companies. International alliances should revolve around issues/strategies identified by workers. International alliances are needed for influencing multinational companies and national governments and lobbying global economic and financial institutions. Standards that are included in social clause discussions are minimum requirements that do not address gender-specific issues. Women Working Worldwide is developing a position statement of social clauses that incorporates a women's perspective. PMID:12347718

    Following the global trend of sustainable development, development of green economy is the best way of slowing the negative ecological and environmental impact. This research establishes the Taiwan's green economic indicators based on the ecological footprint and energy analysis. The results are as follows: Taiwan's ecological footprint in 2008 intensity index was at 4.364; ecological overshoot index was at 3.364, showing that Taiwan's ecological system is in overload state. Moreover, this study utilizes energy analysis model to study the sustainable development of Taiwan. Findings showed that total energy use in 2008 was 3.14 × 10(23) sej (solar energy joule, sej), energy of renewable resources was 1.30 × 10(22) sej, energy of nonrenewable resources was 2.26 × 10(23) sej, energy of products from renewable resources was 1.30 × 10(22)sej, energy of currency flow was 8.02 × 10(22) sej and energy of wastes flow was 6.55 × 10(22) sej. Taiwan's energy per capita and the utilization rate of energy is lower while the environmental loading rate is significantly higher comparing to some other countries. The foregoing findings indicate that Taiwan currently belongs to an economic development pattern based on high resource consumption. The economic development is mainly established on the exploitation and utilization of nonrenewable resources. Therefore, Taiwan should change the development pattern, regulate the industrial structure, promote the utilization rate of resources, develop green pollution-free products, and enhance the sustainable development of ecological economic system.

    This article reports the results of a case study, spanning a period of 10 years, of the merger of two hospitals in a publicly-funded health system. A political economy model was used to analyse the determinants of the merger. Results show that external political economy factors, mainly pressure from the state to rationalize health services and the organization's needs to acquire critical resources, significantly contributed to the merger decision. At the internal political economy level, groups and individual strategies also played a determinant role. Our study suggests that merger in the public sector may not necessarily result from efficiency motives. PMID:10122103

    Session ERE5.1 Climate change impact on economical and industrial activities The impact of climate change on the BRICS economies: The case of insurance demand. Over the past decade, growth in the BRICS (Brazil, Russia, India, China and South Africa) economies has been a key driver of global economic growth. Current forecasts suggest that these markets will continue to be areas of significant growth for a large number of industries. We consider how climate change may influence these trends in the period to 2030, a time horizon that is long in terms of strategic planning in industry, but relatively short for climate change analysis, where the impacts are predicted to be most significant beyond around 2050. Based on current evidence, we expect climate change to affect the BRICS economies in four main ways: 1. The impact of physical climatic changes on the productivity of climate-sensitive economic activity, the local environment, human health and wellbeing, and damages from extreme weather. 2. Changing patterns of investment in climate risk management and adaptation 3. Changing patterns of investments in areas affected by greenhouse gas (GHG) mitigation policy, 4. The impacts of the above globally, including on international trade, growth, investment, policy, migration and commodity prices, and their impacts on the BRICS. We review the evidence on the impacts of climate change in the BRICS and then apply this to one particular industry sector: non-life insurance. We propose five potential pathways through which climate change could influence insurance demand: economic growth; willingness to pay for insurance; public policy and regulation; the insurability of natural catastrophe risks; and new opportunities associated with adaptation and greenhouse gas mitigation. We conclude that, with the exception of public policy and regulation, the influence of climate change on insurance demand to 2030 is likely to be small when compared with the expected growth due to rising incomes. The scale of the impacts and their direction depend to some extent on (re)insurer responses to the challenges of climate change. We outline five actions that could pave the way for future opportunities in the industry.

    Three children diagnosed with attention deficit hyperactivity disorder (ADHD) participated in a summer program designed to evaluate the influence of stimulant medication and a token economy on attentive and disruptive behavior during kickball games. Attentive and disruptive behavior were assessed using an interval coding system, and daily ratings on the ADHD Index of the Conners Teacher Rating Scale-Revised were also obtained. A multielement reversal design was used, and the results indicated that both interventions independently improved attentive behavior and decreased disruptive behavior for the participants. Contrary to other research, when the token economy and medication were compared in isolation, the token system appeared more effective in reducing disruptive behavior for 2 of the 3 participants. In addition, the token system generally enhanced the effects of stimulant medication. PMID:11317639

  1. Public health challenges in the political economy of conflict: the case of Syria.

    2015-01-01

    Recent uprisings in the Arab world and a full-scale war in Syria are widely viewed as popular demand for political voice against repressive regimes. However, growing economic inequalities and serious economic dysfunction played a role as trigger for conflict than is commonly accepted. Tunisia, Egypt and Syria all implemented policies of liberalization over the past two decades, leading to the worsening of living standards for the majority. The various forms of liberalization played a significant role in embedding social division and discontent whose outcomes affected other countries of the region with the onset of market reforms in nascent welfare states. Egypt, for example, was viewed by the World Bank as an economic 'best performer', despite regular riots over food prices, job losses and land expropriation for tourism. Tunisia was praised by donors just prior to the uprising (in 2010), for 'weathering well' the global economic downturn through 'sound macroeconomic management'. In Syria, the market economy made its mark over the 90s, but macroeconomic adjustment policies were implemented in a bilateral agreement with the European Union and approved by the International Monetary Fund in 2003. The economic stabilization programme that followed had limited concern for social impacts such as jobs losses, price rises and national debt, which ultimately caused immense hardship for the population at large, acting as a trigger for the initial uprising in 2011, prior to its transformation into a fully blown conflict. This article focuses on reforms implemented in the health sector and sets these in the context of the current political economy of Syria. It suggests that a protective approach to public health services during and in the aftermath of conflict may increase the possibilities of reconstruction and reconciliation between warring sides.

    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.

  5. Energy economy of salmon aquaculture in the Baltic sea

    NASA Astrophysics Data System (ADS)

    Folke, Carl

    1988-07-01

    Resource utilization in Atlantic salmon aquaculture in the Baltic Sea was investigated by means of an energy analysis. A comparison was made between cage farming and sea ranching enterprises each with yearly yields of 40 t of Atlantic salmon. A variety of sea ranching options were evaluated, including (a) conventional ranching, (b) ranching employing a delayed release to the sea of young smolts, (c) harvesting salmon both by offshore fishing fleets and as they return to coastal areas, and (d) when offshore fishing is banned, harvesting salmon only as they return to coastal areas where released. Inputs both from natural ecosystems (i.e., fish consumed by ranched salmon while in the sea and raw materials used for producing dry food pellets) and from the economy (i.e., fossil fuels and energy embodied in economic goods and services) were quantified in tonnes for food energy and as direct plus indirect energy cost (embodied energy). The fixed solar energy (estimated as primary production) and the direct and indirect auxiliary energy requirements per unit of fish output were expressed in similar units. Similar quantities of living resources in tonnes per unit of salmon biomass output are required whether the salmon are feeding in the sea or are caged farmed. Cage farming is about 10 times more dependent on auxiliary energies than sea ranching. Sea ranching applying delayed release of smolts is 35 45% more efficient in the use of auxiliary energies than conventional sea ranching and cage farming. Restriction of offshore fishing would make sea ranching 3 to 6.5 times more efficient than cage farming. The fixed solar energy input to Atlantic salmon aquaculture is 4 to 63 times larger than the inputs of auxiliary energy. Thus, cage farming and sea ranching are both heavily dependent on the productivity of natural ecosystems. It is concluded that sustainable development of the aquaculture industry must be founded on ecologically integrated technologies which utilize the free production in marine ecosystems without exhausting or damaging the marine environment.

  6. Thermodynamic accounting of ecosystem contribution to economic sectors with application to 1992 U.S. economy.

    2004-09-15

    Incorporation of ecological considerations in decision-making is essential for sustainable development, but is hindered by inadequate appreciation of the role of ecosystems, and lack of scientifically rigorous techniques for including their contribution. This paper develops a novel thermodynamic accounting framework for including the contribution of natural capital via thermodynamic input-output analysis. This framework is applied to the 1992 US economy comprising 91 industry sectors, resulting in delineation of the myriad ways in which sectors of the US economy rely on ecosystem products and services. The contribution of ecosystems is represented via the concept of ecological cumulative exergy consumption (ECEC), which is related to emergy analysis but avoids any of its controversial assumptions and claims. The use of thermodynamics permits representation of all kinds of inputs and outputs in consistent units, facilitating the definition of aggregate metrics. Total ECEC requirement indicates the extent to which each economic sector relies directly and indirectly on ecological inputs. The ECEC/money ratio indicates the relative monetary versus ecological throughputs in each sector, and indicates the relationship between the thermodynamic work needed to produce a product or service and the corresponding economic activity. This ratio is found to decrease along economic supply chains, indicating industries that are higher up in the economic food chain price ecosystem contribution more than the basic infrastructure industries such as mining and manufacturing. The ratio of CEC with and without inclusion of ecosystems indicates the extent to which conventional thermoeconomic analysis underestimates the contribution of ecosystems. Such ratios, made available for the first time, provide unique insight into the importance of natural capital, and are especially useful in hybrid thermodynamic life cycle analysis of industrial systems. The approach, data compiled in this work, and the resulting insight provide a more ecologically conscious tool for environmental decision-making, and has potential applications at micro as well as macro scales.

    We argue about the application of methods of statistical mechanics to free economy (Kusmartsev F. V., Phys. Lett. A, 375 (2011) 966) and find that the most general distribution of money or income in a free-market economy has a general Bose-Einstein distribution form. Therewith the market is described by three parameters: temperature, chemical potential and the space dimensionality. Numerical simulations and a detailed analysis of a generic model confirm this finding.

    One impediment to increasing the fuel economy standards forlight-duty vehicles is the long-standing argument that reducing vehiclemass to improve fuel economy will inherently make vehicles less safe.This technical paper summarizes and examines the research that is citedin support of this argument, and presents more recent research thatchallenges it. We conclude that the research claiming that lightervehicles are inherently less safe than heavier vehicles is flawed, andthat other aspects of vehicle design are more important to the on-roadsafety record of vehicles. This paper was prepared for a workshop onexperts in vehicle safety and fuel economy, organized by the William andFlora Hewlett Foundation, to discuss technologies and designs that can betaken to simultaneously improve vehicle safety and fuel economy; theworkshop was held in Washington DC on October 3, 2006.

    Nitrogen (N) interacts strongly with climate change in determining the severity and extent of many human health and environmental issues, such as eutrophication, poor air quality, and the maintenance of a secure food system. We were motivated by such N-climate interactions and their environmental impacts as part of a broader assessment of N in the continental United States. We here seek to identify and quantify inefficiencies associated with intentional N creation (i.e., creating synthetic N fertilizers and cultivating N-fixing legumes) among the major N-dependent sectors of the United States economy. We define efficiency of N use as the proportion N directly incorporated into food, fiber, biofuel, and industrial goods from the pool of intentionally created N. We are interested in whether reductions in N use could be achieved without changing the current functioning of the major N-dependent economic sectors. Our analysis points to substantial inefficiencies in N use at the national scale. A large percentage of the N applied as synthetic fertilizer and fixed by legumes annually fails to enter the United States food supply. Much of the unincorporated N enters air, land and water, where it can impact human health and ecosystems. The climate change forcing of N is uncertain, though it appears that the combined effects of intentionally and unintentionally created N on climate is roughly neutral in the United States (i.e., net effect of N-enhanced C storage, nitrous oxide emissions, N-based aerosols, and tropospheric ozone on climate forcing). Thus, it is reasonable to expect that improved efficiencies in N use would have minimal negative side effects on the United States economy, human health and the environment. We suggest that policies aimed at improving N-use efficiencies are an alternative to direct climate mitigation strategies in offsetting several impacts of climate change on human health and ecosystem functioning.

  11. The Role of Agriculture in Turkish Economy at the Beginning of the European Union Accession Negotiations

    NASA Astrophysics Data System (ADS)

    Tanrivermis, Harun; Bulbul, Mehmet

    In this study, Turkish economy and importance of agriculture in the economy on the way of accession negotiations to the European Union (EU) are discussed. Compliance with EU norms based on macroeconomic indicators is evaluated. Turkish economy exhibits the characteristics of a developing economy based on per capita income, economic growth, employment, income distribution, foreign trade volume and economic structure. Long-term economic growth rate of Turkey is quite low and it is negatively affected by economic crises. Income distribution among the households and the regions (both of the geographical and rural-urban regions) is imbalanced. Income per capita is about ¼ of an average developed country and the economy is still characterized by a high degree of dualism in the economic sectors, regions as well as social segments. Economy suffers from trade deficit and the level of agricultural import has almost reached to agricultural export`s level in 2004. From the point of view of all socio-economic indicators, the contribution of agricultural production to domestic economy is essential in terms of employment, contributing to national income and export earnings. The enterprise size is relatively small, duality in socio-economic structure is common, population is high, productivity level is low, costs are high and competition power of some sub-sectors is low in Turkish agricultural sector. Small family farms are the main unit of crops and livestock production and household members provide most of the labor requirements of the farms. Turkey launched a radical change in agricultural policy instead of unsustainable and costly system of support policies including input subsidies and support prices and issued a policy paper for 2006-2010 in line with the Common Agricultural Policy of the EU. Reevaluation of the agricultural policies is needed in order to minimize the regional development differences and to control the migration from rural areas to cities.

  12. Environmental and Health Benefits and Risks of a Global Hydrogen Economy

    Rapid development in hydrogen fuel-cell technologies will create a strong impetus for a massive hydrogen supply and distribution infrastructure in the coming decades. Hydrogen provides an efficient energy carrier that promises to enhance urban and regional air quality that will benefit human health. It could also reduce risks of climate change if large-scale hydrogen production by renewable or nuclear energy sources becomes viable. While it is well known that the byproduct of energy produced from hydrogen is water vapor, it is not well known that the storage and transfer of hydrogen is inevitably accompanied by measurable leakage of hydrogen. Unintended consequences of hydrogen leakage include reduction in global oxidative capacity, changes in tropospheric ozone, and increase in stratospheric water that would exacerbate halogen induced ozone losses as well as impact the earth's radiation budget and climate. Stratospheric ozone depletion would increase exposure to harmful ultraviolet radiation and increased risk to melanoma. We construct plausible global hydrogen energy use and leak scenarios and assess their impacts using global 3-D simulations by the Model for Ozone And Related Trace species (MOZART). The hydrogen fluxes and photochemistry in our model successfully reproduce the contemporary hydrogen cycle as observed by a network of remote global stations. Our intent is to determine environmentally tolerable leak rates and also facilitate a gradual phasing in of a hydrogen economy over the next several decades as the elimination of the use of halocarbons gradually reduces halogen induced stratospheric ozone loss rates. We stress that the future evolution of microbial soil sink of hydrogen that determines its current lifetime (about 2 years) is the principal source of uncertainty in our assessment. We propose global monitoring of hydrogen and its deuterium content to define a baseline and track its budget to responsibly prepare for a global hydrogen economy.

    The theory of the firm is of considerable interest in economics. The standard microeconomic theory of the firm is largely a static model and has thus proved unsatisfactory for addressing inherently dynamic issues such as the growth of economies. In recent years, many have attempted to develop richer models that provide a more accurate representation of firm dynamics due to learning, innovative effort, and the development of organizational infrastructure. The validity of these new, inherently dynamic theories depends on their consistency with the statistical properties of firm growth, e.g. the relationship between growth rates and firm size. Using the Compustat database over the time period 1975-1991, we find: (i) the distribution of annual growth rates for firms with approximately the same sales displays an exponential form with the logarithm of growth rate, and (ii) the fluctuations in the growth rates --- measured by the width of this distribution --- scale as a power law with the firm sales. We place these findings of scaling behavior in the context of conventional economics by considering firm growth dynamics with temporal correlations and also, by considering a hierarchical organization of the departments of a firm.

    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

    In this paper, we apply the detrended fluctuation analysis (DFA), local scaling detrended fluctuation analysis (LSDFA), and detrended cross-correlation analysis (DCCA) to investigate correlations of several stock markets. DFA method is for the detection of long-range correlations used in time series. LSDFA method is to show more local properties by using local scale exponents. DCCA method is a developed method to quantify the cross-correlation of two non-stationary time series. We report the results of auto-correlation and cross-correlation behaviors in three western countries and three Chinese stock markets in periods 2004-2006 (before the global financial crisis), 2007-2009 (during the global financial crisis), and 2010-2012 (after the global financial crisis) by using DFA, LSDFA, and DCCA method. The findings are that correlations of stocks are influenced by the economic systems of different countries and the financial crisis. The results indicate that there are stronger auto-correlations in Chinese stocks than western stocks in any period and stronger auto-correlations after the global financial crisis for every stock except Shen Cheng; The LSDFA shows more comprehensive and detailed features than traditional DFA method and the integration of China and the world in economy after the global financial crisis; When it turns to cross-correlations, it shows different properties for six stock markets, while for three Chinese stocks, it reaches the weakest cross-correlations during the global financial crisis.

  1. The Uncontrolled Economic Engine of the Developing Economies, Speeding up the Climate Shift

    2014-12-01

    As we progress into the 21st century, the world faces challenges of truly global nature bearing implications on the whole world in one way or another. The global economic engine has shifted from the western world (Developed Economies) to the eastern world (Developing Economies) which has brought about tremendous change in the climate related variables in this part of the world. As uncontrolled carbon emissions grow in the developing economies, the phenomenon of global warming and climate shifts become more and more prevalent. While this economic activity provides income for millions of households, it is contributing generously to the rapid degradation of the environment. Developing economies as it has been seen do not employ or abide by stringent regulations regarding emissions which result in uncontrolled emissions. In this particular scenario, it is a tedious task to convince governments in the developing economies to implement regulations regarding emissions because businesses in these economies deem such regulations to be economically unviable. The other side of the problem is that these uncontrolled emission are causing evident climate shifts which has had adverse impacts on the agricultural societies where shifting climates are leading to reduced agricultural output and productivity. Consequently the lives of millions associated directly or indirectly with agriculture are affected and on a more global level, the agricultural produce is decreasing which increases the chances of famine in parts of the world. The situation could have devastating impacts on the global economy and environmental standards and therefore needs to be addressed on emergency basis. The first step towards betterment could be the introduction of the carbon trading economy in the developing economies which would incentivize emission reduction and become more attractive and in the process sustaining minimum possible damage to the environment. Though carbon trading is a formidable first step in the right direction, it is in no way the only step and many other steps need to be taken. Agricultural economies have to study climate changes in detail and inculcate findings into their agricultural practices in order to keep the productivity from reducing.

    This manual reviews the derivation of the similitude relationships believed to be important to ice accretion and examines ice-accretion data to evaluate their importance. Both size scaling and test-condition scaling methods employing the resulting similarity parameters are described, and experimental icing tests performed to evaluate scaling methods are reviewed with results. The material included applies primarily to unprotected, unswept geometries, but some discussion of how to approach other situations is included as well. The studies given here and scaling methods considered are applicable only to Appendix-C icing conditions. Nearly all of the experimental results presented have been obtained in sea-level tunnels. Recommendations are given regarding which scaling methods to use for both size scaling and test-condition scaling, and icing test results are described to support those recommendations. Facility limitations and size-scaling restrictions are discussed. Finally, appendices summarize the air, water and ice properties used in NASA scaling studies, give expressions for each of the similarity parameters used and provide sample calculations for the size-scaling and test-condition scaling methods advocated.

    The Antimatter Economy will bring every country into the 21st century without destroying our environment and turn the Star Trek dream into reality by using antimatter from comets. 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.

  9. Predicting Light-Duty Vehicle Fuel Economy as a Function of Highway Speed

    SciTech Connect

    Thomas, John F; Hwang, Ho-Ling; West, Brian H; Huff, Shean P

    2013-01-01

    The www.fueleconomy.gov website offers information such as window label fuel economy for city, highway, and combined driving for all U.S.-legal light-duty vehicles from 1984 to the present. The site is jointly maintained by the U.S. Department of Energy and the U.S. Environmental Protection Agency (EPA), and also offers a considerable amount of consumer information and advice pertaining to vehicle fuel economy and energy related issues. Included with advice pertaining to driving styles and habits is information concerning the trend that as highway cruising speed is increased, fuel economy will degrade. An effort was undertaken to quantify this conventional wisdom through analysis of dynamometer testing results for 74 vehicles at steady state speeds from 50 to 80 mph. Using this experimental data, several simple models were developed to predict individual vehicle fuel economy and its rate of change over the 50-80 mph speed range interval. The models presented require a minimal number of vehicle attributes. The simplest model requires only the EPA window label highway mpg value (based on the EPA specified estimation method for 2008 and beyond). The most complex of these simple model uses vehicle coast-down test coefficients (from testing prescribed by SAE Standard J2263) known as the vehicle Target Coefficients, and the raw fuel economy result from the federal highway test. Statistical comparisons of these models and discussions of their expected usefulness and limitations are offered.

    2015-01-01

    This paper presents an analysis of factors influencing job satisfaction in post-transition economies on the example of the Czech Republic. Our research shows that women reported higher levels of job satisfaction compared to men. Education proved to be statistically significant in one of three indicators of job satisfaction. Personal income and workplace relationships proved to be positively and significantly related to all the three indicators of job satisfaction. Most of the occupational dummies were significantly related to two out of three indicators of job satisfaction. In addition, we found that Czech entrepreneurs enjoy and value their job, which indicates strong self-selection for doing business in post-transition economies. However, human capital expressed by the level of education was significant factor for job satisfaction, meaning that well-educated people might not be satisfied with their jobs or feel that their education and experience are wasted in the market economy.

    Input-output tables describe the flows of goods and services between the sectors of an economy. These tables can be interpreted as weighted directed networks. At the usual level of aggregation, they contain nodes with strong self-loops and are almost completely connected. We derive two measures of node centrality that are well suited for such networks. Both are based on random walks and have interpretations as the propagation of supply shocks through the economy. Random walk centrality reveals the vertices most immediately affected by a shock. Counting betweenness identifies the nodes where a shock lingers longest. The two measures differ in how they treat self-loops. We apply both to data from a wide set of countries and uncover salient characteristics of the structures of these national economies. We further validate our indices by clustering according to sectors’ centralities. This analysis reveals geographical proximity and similar developmental status.

  20. Costs and benefits of automotive fuel economy improvement: A partial analysis

    1992-03-01

    This paper is an exercise in estimating the costs and benefits of technology-based fuel economy improvements for automobiles and light trucks. Benefits quantified include vehicle cots, fuel savings, consumer's surplus effects, the effect of reduced weight on vehicle safety, impacts on emissions of CO{sub 2} and criteria pollutants, world oil market and energy security benefits, and the transfer of wealth from US consumes to oil producers. A vehicle stock model is used to capture sales, scrappage, and vehicle use effects under three fuel price scenarios. Three alternative fuel economy levels for 2001 are considered, ranging from 32.9 to 36.5 MPG for cars and 24.2 to 27.5 MPG for light trucks. Fuel economy improvements of this size are probably cost-effective. The size of the benefit, and whether there is a benefit, strongly depends on the financial costs of fuel economy improvement and judgments about the values of energy security, emissions, safety, etc. Three sets of values for eight parameters are used to define the sensitivity of costs and benefits to key assumptions. The net present social value (1989$) of costs and benefits ranges from a cost of $11 billion to a benefit of $286 billion. The critical parameters being the discount rate (10% vs. 3%) and the values attached to externalities. The two largest components are always the direct vehicle costs and fuel savings, but these tend to counterbalance each other for the fuel economy levels examined here. Other components are the wealth transfer, oil cost savings, CO{sub 2} emissions reductions, and energy security benefits. Safety impacts, emissions of criteria pollutants, and consumer's surplus effects are relatively minor components. The critical issues for automotive fuel economy are therefore: (1) the value of present versus future costs and benefits, (2) the values of external costs and benefits, and (3) the financially cost-effective level of MPG achievable by available technology. 53 refs.

    Health is a critical dimension of human well-being and flourishing, and oral health is an integral component of health: one is not healthy without oral health. Significant barriers exist to ensuring the world's people receive basic healthcare, including oral healthcare. Amongst these are poverty, ignorance, inadequate financial resources and lack of adequate numbers of educated and trained (oral) healthcare workers. Emerging economies are encouraged to develop a national strategic plan for oral health. International organizations have developed goals for oral health that can be referenced and adapted by emerging economies as they seek to formulate specific objectives for their countries. Demographic data that assess the nature and extent of oral diseases in a country are essential to sound planning and the development of an oral healthcare system that is relevant, effective and economically viable. Prevention should be emphasized and priority consideration be given to oral healthcare for children. The types and numbers of members of the oral healthcare team (workforce) will vary from country to country depending on the system developed. Potential members of the workforce include: generalist dentists, specialist dentists, dental therapists, dental hygienists, denturists, expanded function dental assistants (dental nurses) and community oral health workers/aides. Competences for dentists, and other members of the team, should be developed to ensure quality care and developed economies should cooperate with emerging economies. The development, by more advanced economies, of digital, virtual curricula, which could be used by emerging economies for educating and training members of the oral healthcare team, should be an important initiative. The International Federation of Dental Educators and Associations (IFDEA) should lead in such an effort. PMID:18289274

    Twelve behaviors selected for reinforcement among 16 chronic psychiatric inpatients were divided into four classes: (a) personal hygiene, (b) personal management, (c) ward work, and (d) social skills. A token economy program was introduced for each class in a sequential, cumulative, multiple-baseline format. Corrections were included for methodological deficiencies frequently enountered in past studies. Treatment variables were systematically monitored, and target behavior rates, levels of global individual functioning, general ward behavior, and off-ward behavior were assessed during baseline, implementation, and probe periods. Results indicated abrupt and substantial increases in performance of most target behaviors, significant improvements in global individual functioning (p less than .025), positive changes in general ward behavior, and increases in social interaction during off-ward activities. The findings provide strong evidence for the efficacy of a token economy and indicate that the multiple-baseline design can be a useful method for evaluating token economy programs. PMID:489481

    Objective This study investigates the effect of social and token economy reinforcements on academic achievement of 9th grade boy students with intellectual disabilities in an experimental science class in Tehran Province. Method The method used for this study was experimental by pre-test, post- test with a control group. The boy students with intellectual disabilities from three junior high schools participated in this study. The sample consisted of thirty, 9th grade boy students with intellectual disabilities in the selected schools; the schools were chosen by the multi-stage cluster method. To measure the progress of students in the science class, a teacher made test and the Wechsler intelligence test for matching the groups for IQ were used. To ensure validity, the content validity criteria depended tests calculated by the Lashe method and teachers' perspective were used. The reliability coefficient was obtained by the reliability coefficient of related tests; the percent agreement method and the obtained data were analyzed using one-way variance analysis and Shefe prosecution test. Results The results showed that there was a significant increase in academic achievement of students with intellectual disabilities when using token economy than using social reinforcements compared with the control group. Also, when using social reinforcements, the academic achievement of students was more than the control group. Conclusion Token economy and social reinforcements increased the academic achievement of students with intellectual disabilities in the science class; and also the effect of token economy reinforcements was more than social reinforcements on the subjects.

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

    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

J Strength Cond Res 30(3): 763-767, 2016-Backwards running (BR) results in greater cardiopulmonary response and muscle activity compared with forward running (FR). BR has traditionally been used in rehabilitation for disorders such as stroke and lower leg extremity injuries, as well as in short bursts during various athletic events. The aim of this study was to measure the effects of sustained backwards running training on forward running economy in trained male athletes. Eight highly trained, male runners (26.13 ± 6.11 years, 174.7 ± 6.4 cm, 68.4 ± 9.24 kg, 8.61 ± 3.21% body fat, 71.40 ± 7.31 ml·kg·min) trained with BR while harnessed on a treadmill at 161 m·min for 5 weeks following a 5-week BR run-in period at a lower speed (134 m·min). Subjects were tested at baseline, postfamiliarized, and post-BR training for body composition, a ramped V[Combining Dot Above]O2max test, and an economy test designed for trained male runners. Subjects improved forward running economy by 2.54% (1.19 ± 1.26 ml·kg·min, p = 0.032) at 215 m·min. V[Combining Dot Above]O2max, body mass, lean mass, fat mass, and % body fat did not change (p > 0.05). Five weeks of BR training improved FR economy in healthy, trained male runners without altering V[Combining Dot Above]O2max or body composition. The improvements observed in this study could be a beneficial form of training to an already economical population to improve running economy. PMID:26332781

    It is often assumed that natural gas exploration and development in the Marcellus Shale will bring great economic prosperity to state and local economies. Policymakers need accurate economic information on which to base decisions regarding permitting and regulation of shale gas extraction. This paper provides a summary review of research findings on the economic impacts of extractive industries, with an emphasis on peer-reviewed studies. The conclusions from the studies are varied and imply that further research, on a case-by-case basis, is necessary before definitive conclusions can be made regarding both short- and long-term implications for state and local economies.

    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

  6. The political economy of oil in post-Soviet Kazakhstan

    NASA Astrophysics Data System (ADS)

    Omarova, Saule Tarikhovna

    This dissertation examines the way in which the Kazakhstani state redefined its role in managing oil and gas resources between 1992 and 1998. The governments of hydrocarbon-rich post-Soviet republics such as Russia, Kazakhstan, Azerbaijan, and Turkmenistan faced the common challenge of restructuring their petroleum industries to boost the export of oil and gas. This study argues that by 1998 three patterns have emerged, ranging from a more radical state retrenchment in Russia, to reinforced state monopoly in Azerbaijan and Turkmenistan, to a "mixed" pattern of state participation in Kazakhstan, consisting of both large-scale privatization of oil assets and the formation of a fully state-owned national oil company, Kazakhoil. This dissertation analyzes the process of restructuring Kazakhstan's oil sector through comparison with the Russian petroleum industry. In Russia, several private, vertically integrated oil companies (VICs) were formed on the basis of existing oil-producing units and soon emerged as essential players in the Russian oil sector. By contrast, Kazakhstan's marginalized status within the Soviet system of oil production resulted in the absence of organizationally strong sectoral interests capable of claiming control over the industry after the independence. Privatization of Kazakhstan's oil enterprises, conducted by the government in spite of the resistance from local oil managers, transferred controlling stakes to foreign investors and further weakened domestic oil interests. Unencumbered state autonomy allowed the increasingly authoritarian Kazakhstani government to adopt relatively modern and investor-friendly petroleum legislation by decree. In Russia, the government's efforts to reform oil-related legislation were blocked by the leftist-dominated Duma, the democratically elected lower chamber of the Russian parliament. On the basis of these findings, this dissertation concludes that the dynamics of state withdrawal from the oil sector in post-Soviet context are determined primarily by structural organization of domestic oil industry inherited from the Soviet era, resulting balance of power between the state and private sectoral actors, and general mode of state-society relations in each country.

  7. My Morning Coffee: The Effect of Climate Change on the Economies of Coffee-Producing Countries

    Through its effect on export crops, climate change will have important effects on economic systems and government capacity in sub-Saharan Africa. We show that climate change effects on three important export crops - coffee, cocoa and cotton - will undermine large portions of the economy, not just the rural farmers who grow these crops. Our analysis is based high-resolution data on crop location, temperature, and water requirements in conjunction with new projections for temperature increases and precipitation changes in sub-Saharan Africa. Our focus on export crops is distinct from most work on the effects of climate change on agriculture, which often focuses on subsistence and food crops. We posit that substantial and important effects on the economy and political systems will come from negative impacts on cash crops, which underpin many economies in sub-Saharan Africa. For instance, 3% of cropland in Uganda (and 2% in Ethiopia) is used for coffee production and over 3.5 million households are involved in the sector; by contrast, 7% of cropland in Uganda (and 11% in Ethiopia) is used for maize, which contributes much less to the formal economy. The relationship between the value of coffee exported and government revenue illustrates the importance of coffee to political and economic stability. A drop in the export value of coffee by 10% in Uganda will drive government revenue down by 20%, and while there is uncertainty around the exact impact of climate change, it is likely that production will take a turn for the worse. We use these factors to assess reliance of select country's economy on these crops, from the farmer to the exporter; the sensitivity of the crops to variation in the climate; and the subsequent impact on government capacity. Our research illustrates how strongly the impacts of climate change are linked to economic and political structures.

  8. Evaluating the Mechanism of Oil Price Shocks and Fiscal Policy Responses in the Malaysian Economy

    2013-06-01

    The paper aims to explore the symmetric impact of oil price shock on economy, to understand its mechanism channel and how fiscal policy response towards it. The Generalized Impulse Response Function and Variance Decomposition under the VAR methodology were employed. The empirical findings suggest that symmetric oil price shock has a positive and direct impact on oil revenue and government expenditure. However, the real GDP is vulnerable in a short-term but not in the long term period. These results would confirm that fiscal policy is the main mechanism channel that mitigates the adverse effects oil price shocks to the economy.

    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.

  1. Three essays on the effects of oil prices on state economies

    NASA Astrophysics Data System (ADS)

    Kang, Wei

    2011-12-01

    This dissertation consists of three chapters that examine the effects of oil prices on state economies. The first chapter, "Asymmetric Effects of Oil Prices on State Economies," examines the impact of oil price changes on state-level income growth. I find strong evidence of asymmetry in the impacts of oil prices and that states vary considerably in terms of sensitivity to oil price shocks. Further analysis shows that states with a higher prevalence of manufacturing and higher coal production are more likely to be negatively affected by positive oil price shocks, while states with a high prevalence of petroleum and natural gas production tend to benefit from positive oil price shocks. The second chapter, "Regime-Switching Analysis of a State Economy's Response to An Oil Price Shock," analyzes the effects of oil price changes on state economies using a smooth transition autoregressive (STAR) approach. States are shown to present differences in both the tolerance and speed of response to an oil price shock. The differences are further explained by state-specific economic characteristics. The third chapter, "Multivariate Unobserved Component Analysis of State Employment with Oil Price Volatility," investigates whether and how oil price volatility affects state employment, with a focus on regional similarities and differences. Results show that oil price volatility has significant negative impacts on most states. Further, states with a higher prevalence of motor vehicle production are likely to experience larger job losses during periods of high oil price volatility.

    The methanol-to-olefins (MTO) process is becoming the most important non-petrochemical route for the production of light olefins from coal or natural gas. Maximizing the generation of the target products, ethene and propene, and minimizing the production of byproducts and coke, are major considerations in the efficient utilization of the carbon resource of methanol. In the present work, the heterogeneous catalytic conversion of methanol was evaluated by performing simultaneous measurements of the volatile products generated in the gas phase and the confined coke deposition in the catalyst phase. Real-time and complete reaction profiles were plotted to allow the comparison of carbon atom economy of methanol conversion over the catalyst SAPO-34 at varied reaction temperatures. The difference in carbon atom economy was closely related with the coke formation in the SAPO-34 catalyst. The confined coke compounds were determined. A new type of confined organics was found, and these accounted for the quick deactivation and low carbon atom economy under low-reaction-temperature conditions. Based on the carbon atom economy evaluation and coke species determination, optimized operating conditions for the MTO process are suggested; these conditions guarantee high conversion efficiency of methanol.

  3. Mass impacts on fuel economies of conventional vs. hybrid electric vehicles.

    SciTech Connect

    An, F.; Santini, D. J.; Energy Systems

    2004-01-01

    The strong correlation between vehicle weight and fuel economy for conventional vehicles (CVs) is considered common knowledge, and the relationship of mass reduction to fuel consumption reduction for conventional vehicles (CVs) is often cited without separating effects of powertrain vs. vehicle body (glider), nor on the ground of equivalent vehicle performance level. This paper challenges the assumption that this relationship is easily summarized. Further, for hybrid electric vehicles (HEVs) the relationship between mass, performance and fuel consumption is not the same as for CVs, and vary with hybrid types. For fully functioning (all wheel regeneration) hybrid vehicles, where battery pack and motor(s) have enough power and energy storage, a very large fraction of kinetic energy is recovered and engine idling is effectively eliminated. This paper assesses two important impacts of shifting from conventional to hybrid vehicles in terms of the mass vs. fuel economy relationship - (1) significant improvements in fuel economy with little or no change in mass, and (2) once a switch to hybrid powertrains has been made, the effectiveness of mass reduction in improving fuel economy will be diminished relative to conventional vehicles. In this paper, we discuss vehicle tractive load breakdowns and impacts of hybridization on vehicle efficiency, discuss capture of kinetic energy by conversion to electrical energy via regenerative braking, assess benefits of shutting off the engine when the vehicle does not require power, and investigate energy losses associated with vehicle mass.

    Kellie-Smith, Owen; Cox, Peter M

    2011-03-13

    Global CO(2) emissions are understood to be the largest contributor to anthropogenic climate change, and have, to date, been highly correlated with economic output. However, there is likely to be a negative feedback between climate change and human wealth: economic growth is typically associated with an increase in CO(2) emissions and global warming, but the resulting climate change may lead to damages that suppress economic growth. This climate-economy feedback is assumed to be weak in standard climate change assessments. When the feedback is incorporated in a transparently simple model it reveals possible emergent behaviour in the coupled climate-economy system. Formulae are derived for the critical rates of growth of global CO(2) emissions that cause damped or long-term boom-bust oscillations in human wealth, thereby preventing a soft landing of the climate-economy system. On the basis of this model, historical rates of economic growth and decarbonization appear to put the climate-economy system in a potentially damaging oscillatory regime. PMID:21282151

  13. Development of scale inhibitors

    SciTech Connect

    Gill, J.S.

    1996-12-01

    During the last fifty years, scale inhibition has gone from an art to a science. Scale inhibition has changed from simple pH adjustment to the use of optimized dose of designer polymers from multiple monomers. The water-treatment industry faces many challenges due to the need to conserve water, availability of only low quality water, increasing environmental regulations of the water discharge, and concern for human safety when using acid. Natural materials such as starch, lignin, tannin, etc., have been replaced with hydrolytically stable organic phosphates and synthetic polymers. Most progress in scale inhibition has come from the use of synergistic mixtures and copolymerizing different functionalities to achieve specific goals. Development of scale inhibitors requires an understanding of the mechanism of crystal growth and its inhibition. This paper discusses the historic perspective of scale inhibition and the development of new inhibitors based on the understanding of the mechanism of crystal growth and the use of powerful tools like molecular modeling to visualize crystal-inhibitor interactions.

  18. An empirical study on the spatial distribution of the population, economy and water resources in Northeast China

    NASA Astrophysics Data System (ADS)

    Zhang, Conglin; Liu, Yu; Qiao, Haijuan

    The relationship among the population, economy and water resources is complex, and the contradictions and conflicts will appear and aggravate with the rapid development of economy and society in Northeast China. Based on the statistical analysis of the available data, this paper depicted the static distribution characteristics of the population, economy and water resources of Northeast China in 2011. It was found that the spatial distribution of the population, economy and water resources was unbalanced in Northeast China. The water resources mismatched with the population and economy. The population and economy were relatively dense and developed in the southwestern part of Northeast China respectively, while the water resources was relatively scarce. However, the situations in the northern part of Northeast China were opposite to those in the southwestern part. The population-economy inconsistence indexes of the cities in northern part of Northeast China showed a significant trend of spatial aggregation and heterogeneity. The cities with lower (<1.5) and higher (>1) inconsistence indexes all faced the problem of water resources shortage. Applying geometric gravity center method and grey correlation model, the result indicated that there was relatively high spatial relevance and the relative deviation among the spatial dynamic distributions of the population, economy and water resources was large. The gravity centers of economy and per capita average annual total water resources moved westward, while the gravity center of population gravity center moved eastward in the period of 1997-2011 in Northeast China. It must be noted that, the migration trend of the economy gravity center was more significant than those of the population and water resources.

    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.

  1. The effects of carbon tax on the Oregon economy and state greenhouse gas emissions

    NASA Astrophysics Data System (ADS)

    Rice, A. L.; Butenhoff, C. L.; Renfro, J.; Liu, J.

    2014-12-01

    Of the numerous mechanisms to mitigate greenhouse gas emissions on statewide, regional or national scales in the United States, a tax on carbon is perhaps one of the simplest. By taxing emissions directly, the costs of carbon emissions are incorporated into decision-making processes of market actors including consumers, energy suppliers and policy makers. A carbon tax also internalizes the social costs of climate impacts. In structuring carbon tax revenues to reduce corporate and personal income taxes, the negative incentives created by distortionary income taxes can be reduced or offset entirely. In 2008, the first carbon tax in North America across economic sectors was implemented in British Columbia through such a revenue-neutral program. In this work, we investigate the economic and environmental effects of a carbon tax in the state of Oregon with the goal of informing the state legislature, stakeholders and the public. The study investigates 70 different economic sectors in the Oregon economy and six geographical regions of the state. The economic model is built upon the Carbon Tax Analysis Model (C-TAM) to provide price changes in fuel with data from: the Energy Information Agency National Energy Modeling System (EIA-NEMS) Pacific Region Module which provides Oregon-specific energy forecasts; and fuel price increases imposed at different carbon fees based on fuel-specific carbon content and current and projected regional-specific electricity fuel mixes. CTAM output is incorporated into the Regional Economic Model (REMI) which is used to dynamically forecast economic impacts by region and industry sector including: economic output, employment, wages, fiscal effects and equity. Based on changes in economic output and fuel demand, we further project changes in greenhouse gas emissions resulting from economic activity and calculate revenue generated through a carbon fee. Here, we present results of this modeling effort under different scenarios of carbon fee and avenues for revenue repatriation.

    Soybean peroxidase (SBP)-catalyzed removal of phenol from wastewater has been demonstrated as a feasible wastewater treatment strategy and a non-ionic surfactant, Triton X-100, has the potential for increasing the enzyme economy of the process. Systematic studies on the enzyme-surfactant system have been lacking as well as demonstration of its applicability to industrial wastewater. This paper addresses those two gaps, the latter based on real wastewater from alkyd resin manufacture. The minimum effective Triton X-100 concentrations for crude SBP-catalyzed phenol conversion (≥95%) over 1-10 mM showed a linear trend. To illustrate translation of such lab results to real-world samples, this data were used to optimize crude SBP needed for phenol conversion over that concentration range. Triton X-100 increases enzyme economy by 10- to 13-fold. This treatment protocol was directly applied to tote-scale (700-1000 L) treatment of alkyd resin wastewater, with phenol ranging from 7 to 28 mM and total organic carbon content of >40 g/L, using a crude SBP extract derived from dry soybean hulls by simple aqueous elution. This extract can be used to remove phenol from a complex industrial wastewater and the process is markedly more efficient in the presence of Triton X-100. The water is thus rendered amenable to conventional biological treatment whilst the hulls could still be used in feed, thus adding further value to the crop. PMID:24411447

  3. Scale of dark QCD

    Most of the mass of ordinary matter has its origin from quantum chromodynamics (QCD). A similar strong dynamics, dark QCD, could exist to explain the mass origin of dark matter. Using infrared fixed points of the two gauge couplings, we provide a dynamical mechanism that relates the dark QCD confinement scale to our QCD scale, and hence provides an explanation for comparable dark baryon and proton masses. Together with a mechanism that generates equal amounts of dark baryon and ordinary baryon asymmetries in the early Universe, the similarity of dark matter and ordinary matter energy densities can be naturally explained. For a large class of gauge group representations, the particles charged under both QCD and dark QCD, necessary ingredients for generating the infrared fixed points, are found to have masses at 1-2 TeV, which sets the scale for dark matter direct detection and novel collider signatures involving visible and dark jets.

  4. Political economy of natural resources: water scarcity in the High Plains region of the US

    1986-01-01

    This dissertation demonstrates the inadequacy of conventional neoclassical economic theories to explain natural resource depletion in a market economy. That theoretical perspective claims that the worry over depletion and scarcity of natural resources results from treating them as unique inputs in the production process. Accordingly, it finds that special controls designed to ration natural resources often lead to erroneous and unintended impacts. An alternative view presented in this dissertation provides a political economic explanation for natural resource scarcity. Importantly, natural resource scarcity and exhaustion result from specific historical developments which define the limits of economic activity. There are conditions unique to a particular nonrenewable resource that determines whether it will be exhausted. A political economic assessment of natural resource depletion utilizing a case study of the High Plains and the declining groundwater in the Ogallala Aquifer finds that exhaustion results from the conflicts and contradictions inherent in a market economy and the structural impediments preventing the state from instituting resource conservation policies.

    In the paper we test robustness of particular dynamic systems in a compact regions of a plane and a weak structural stability of one dynamic system of high order in a compact region of its phase space. The test was carried out based on the fundamental theory of dynamical systems on a plane and based on the conditions for weak structural stability of high order dynamic systems. A numerical algorithm for testing the weak structural stability of high order dynamic systems has been proposed. Based on this algorithm we assess the weak structural stability of one computable general equilibrium model.

    This report describes the development of an agent-based microanalytic simulation model of the US economy. The microsimulation model capitalizes on recent technological advances in evolutionary learning and parallel computing. Results are reported for a test problem that was run using the model. The test results demonstrate the model`s ability to predict business-like cycles in an economy where prices and inventories are allowed to vary. Since most economic forecasting models have difficulty predicting any kind of cyclic behavior. These results show the potential of microanalytic simulation models to improve economic policy analysis and to provide new insights into underlying economic principles. Work already has begun on a more detailed model.

  10. Some evidence on determinants of fuel economy as a function of driving cycle and test type

    1993-08-01

    Statistical methods are used with 107 vehicles whose fuel economy was presented and reported for five test types in a single publication by Consumers Union (CU) for 1986--1988 vehicles. Standard loglinear statistical formulations (i.e., multiplicative models of interactions) are used with data from this and supplementary sources to develop coefficients estimating the percent fuel economy gain per percent change in engine/vehicle design characteristic. The coefficients are developed for the five different test conditions evaluated by CU and are compared with each other on the basis of attributes of the tests. The insights of engineering models are used to develop expectations regarding the shift in size of coefficients as driving cycles change. In both the engineering models and the statistical model, the effect of weight is estimated to be higher in urban driving than in highway driving. For two test categories -- field tests and dynamometer tests -- the benefits of weight reduction are statistically estimated to be greatest in urban driving conditions. The effect on idle fuel flow rate of designing vehicles to hold performance roughly constant by maintaining power per kilogram and/or displacement per kilogram is examined, and its implication for the size of the weight effect is simply approximated from Sovran`s 1983 engineering model results. The fuel-economy-decreasing effect of the desire for performance is estimated to be somewhat larger in the statistical analysis than in the NAS study, when engine technology is held constant.

  11. Nutribusiness: an aspect of the political economy of persistent hunger.

    PubMed

    1984-01-01

    The failure of nutrition programs to significantly impact on the prevalent hunger in underdeveloped countries is attributed to nutribusiness. This term conceptually links the activities of profit-motivated capitalist enterprises to the continuous generation of poverty and hunger. The actors are all part of a hierarchy dominated by multinational corporate interests and including bilateral and multilateral aid agencies, nutrition institutes, and nutrition professionals at various levels. Although many lower-level nutrition workers are unwittingly caught up in the system, most of the higher-level professionals are conscious of their roles, which they selfishly perform for personal advancement. The Philippine nutrition system is examined as an example of nutribusiness, albeit in a very obvious and extreme form. On the available evidence, the conclusion is drawn that in countries dominated by capitalist production, nutrition activities amount to nutribusiness. Consequently, the elimination and prevention of persistent hunger in underdeveloped countries must start with their disengagement from the world capitalist system and their pursuit of socialist transformation.

    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

    We present simulated fuel economy and emissions city transit buses powered by conventional diesel engines and diesel-hybrid electric powertrains of varying size. Six representative city drive cycles were included in the study. In addition, we included previously published aftertreatment device models for control of CO, HC, NOx, and particulate matter (PM) emissions. Our results reveal that bus hybridization can significantly enhance fuel economy by reducing engine idling time, reducing demands for accessory loads, exploiting regenerative braking, and shifting engine operation to speeds and loads with higher fuel efficiency. Increased hybridization also tends to monotonically reduce engine-out emissions, but trends in the tailpipe (post-aftertreatment) emissions involve more complex interactions that significantly depend on motor size and drive cycle details.

    The purpose of this study was to examine the effect of minimalist running shoes on oxygen uptake during running before and after a 10-week transition from traditional to minimalist running shoes. Twenty-five recreational runners (no previous experience in minimalist running shoes) participated in submaximal VO2 testing at a self-selected pace while wearing traditional and minimalist running shoes. Ten of the 25 runners gradually transitioned to minimalist running shoes over 10 weeks (experimental group), while the other 15 maintained their typical training regimen (control group). All participants repeated submaximal VO2 testing at the end of 10 weeks. Testing included a 3 minute warm-up, 3 minutes of running in the first pair of shoes, and 3 minutes of running in the second pair of shoes. Shoe order was randomized. Average oxygen uptake was calculated during the last minute of running in each condition. The average change from pre- to post-training for the control group during testing in traditional and minimalist shoes was an improvement of 3.1 ± 15.2% and 2.8 ± 16.2%, respectively. The average change from pre- to post-training for the experimental group during testing in traditional and minimalist shoes was an improvement of 8.4 ± 7.2% and 10.4 ± 6.9%, respectively. Data were analyzed using a 2-way repeated measures ANOVA. There were no significant interaction effects, but the overall improvement in running economy across time (6.15%) was significant (p = 0.015). Running in minimalist running shoes improves running economy in experienced, traditionally shod runners, but not significantly more than when running in traditional running shoes. Improvement in running economy in both groups, regardless of shoe type, may have been due to compliance with training over the 10-week study period and/or familiarity with testing procedures. Key pointsRunning in minimalist footwear did not result in a change in running economy compared to running in traditional footwear prior to 10 weeks of training.Both groups (control and experimental) showed an improvement in running economy in both types of shoes after 10 weeks of training.After transitioning to minimalist running shoes, running economy was not significantly different while running in traditional or minimalist footwear.

    A system for indicating economy of operation in internal combustion engines in boats so that a specific number of revolutions for fuel economy may be set. Two measuring devices are utilized, the output signal of one being proportional to the number of revolutions of the boat engine, whereas the output signal of the other is proportional to the flow of fuel to the engine. These two signals are compared in an indicator device, which as a result exhibits at least one extreme value in the operational range, whereby it becomes possible to find a favorable number of revolutions for operation with a high degree of efficiency and to avoid numbers of revolutions with a low degree of efficiency in simple manner.

    1946-01-01

    An investigation was conducted to evaluate the possibilities of utilizing the high-performance characteristics of triptane and xylidines blended with 28-R fuel in order to increase fuel economy by the use of high compression ratios and maximum-economy spark setting. Full-scale single-cylinder knock tests were run with 20 deg B.T.C. and maximum-economy spark settings at compression ratios of 6.9, 8.0, and 10.0, and with two inlet-air temperatures. The fuels tested consisted of triptane, four triptane and one xylidines blend with 28-R, and 28-R fuel alone. Indicated specific fuel consumption at lean mixtures was decreased approximately 17 percent at a compression ratio of 10.0 and maximum-economy spark setting, as compared to that obtained with a compression ratio of 6.9 and normal spark setting. When compression ratio was increased from 6.9 to 10.0 at an inlet-air temperature of 150 F, normal spark setting, and a fuel-air ratio of 0.065, 55-percent triptane was required with 28-R fuel to maintain the knock-limited brake power level obtained with 28-R fuel at a compression ratio of 6.9. Brake specific fuel consumption was decreased 17.5 percent at a compression ratio of 10.0 relative to that obtained at a compression ratio of 6.9. Approximately similar results were noted at an inlet-air temperature of 250 F. For concentrations up through at least 20 percent, triptane can be more efficiently used at normal than at maximum-economy spark setting to maintain a constant knock-limited power output over the range of compression ratios tested.

    2010-11-01

    As huge complex systems consisting of geographic regions, natural resources, people and economic entities, countries follow the allometric scaling law which is ubiquitous in ecological, and urban systems. We systematically investigated the allometric scaling relationships between a large number of macroscopic properties and geographic (area), demographic (population) and economic (GDP, gross domestic production) sizes of countries respectively. We found that most of the economic, trade, energy consumption, communication related properties have significant super-linear (the exponent is larger than 1) or nearly linear allometric scaling relations with the GDP. Meanwhile, the geographic (arable area, natural resources, etc.), demographic (labor force, military age population, etc.) and transportation-related properties (road length, airports) have significant and sub-linear (the exponent is smaller than 1) allometric scaling relations with area. Several differences of power law relations with respect to the population between countries and cities were pointed out. First, population increases sub-linearly with area in countries. Second, the GDP increases linearly in countries but not super-linearly as in cities. Finally, electricity or oil consumption per capita increases with population faster than cities.

    We analyze the complexity of rare economic events in troubled European economies. The economic crisis initiated at the end of 2009, forced a number of European economies to request financial assistance from world organizations. By employing the stock market index as a leading indicator of the economic activity, we test whether the financial assistance programs altered the statistical properties of the index. The effects of major financial program agreements on the economies can be best illustrated by the comparison of the multifractal spectra of the time series before and after the agreement. We reveal that the returns of the time series exhibit strong multifractal properties for all periods under investigation. In two of the three investigated economies, financial assistance along with governments’ initiatives appear to have altered the statistical properties of the stock market indexes increasing the width of the multifractal spectra and thus the complexity of the market.

    Thought Experiments of Economic Surplus: Science and Economy in Ernst Mach's Epistemology. Thought experiments are an important element in Ernst Mach's epistemology: They facilitate amplifying our knowledge by experimenting with thoughts; they thus exceed the empirical experience and suspend the quest for immediate utility. In an economical perspective, Mach suggested that thought experiments depended on the production of an economic surplus based on the division of labor relieving the struggle for survival of the individual. Thus, as frequently emphasized, in Mach's epistemology, not only the 'economy of thought' is an important feature; instead, also the socioeconomic conditions of science play a decisive role. The paper discusses the mental and social economic aspects of experimental thinking in Mach's epistemology and examines those within the contemporary evolutionary, physiological, and economic contexts.

    In a long-term transformation, that begins in Antiquity but takes a crucial turn in the Renaissance anatomies, the "fibre" becomes from around 1750 the operative building block and at the same time the first unifying principle of function-structure-complexes of organic bodies. It occupies the role that the cell takes up in the cell economies of the second third of the nineteenth century. In this paper, I will first discuss some key notions, technical analogies, and images that are related to "fibre"-concepts from Andreas Vesalius to Albrecht von Haller and then focus on Charles Bonnet's and Denis Diderot's fibre ceconomies. In Bonnet's and Diderot's fibre economies, the self-active, regulating properties of fibre-agents and their material structures, that reach from fibre bundles, tissues and membranes to apparati of organs, are united within the concrete whole of individual organized "systems" or "networks."

    2012-02-01

    Any decision process requires information about the past and present state of the system, but in an economy acquiring data and processing it is an expensive and time-consuming task. Therefore, the state of the system is often measured over some legal interval, analysed after the end of well defined time periods and the results announced much later before any strategic decision is envisaged. The various time delay roles have to be crucially examined. Here, a model of stock market coupled with an economy is investigated to emphasise the role of the time delay span on the information flow. It is shown that the larger the time delay the more important the collective behaviour of agents since one observes time oscillations in the absolute log-return autocorrelations.

    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. Projected results for the national employment impacts, projections of the job creation and job replacement underlying the total employment changes, training implications, regional employment impacts and the employment impacts of a hydrogen transformation on international competitiveness are investigated and reported.

    Recent management research has indicated the importance of family, sleep, and recreation as nonwork activities of employees. Drawing from entrainment theory, we develop an expanded model of work-life conflict to contend that macrolevel business cycles influence the amount of time employees spend on both work and nonwork activities. Focusing solely on working adults, we test this model in a large nationally representative dataset from the Bureau of Labor Statistics that spans an 8-year period, which includes the "Great Recession" from 2007 through 2009. We find that during economic booms, employees work more and therefore spend less time with family, sleeping, and recreating. In contrast, in recessionary economies, employees spend less time working and therefore more time with family, sleeping, and recreating. Thus, we extend the theory on time-based work-to-family conflict, showing that there are potential personal and relational benefits for employees in recessionary economies.

    2004-12-01

    The promise of a clean, hydrogen (H2)-fueled transportation sector has been waved in front of the nation by the current administration, the governor of California, and the technologists. A 2004 NAS report on "The Hydrogen Economy" was prepared by the economists and engineers, remarkably lacking any atmospheric scientists or biogeochemists who understand the natural cycle of H2. It is surprising that all of these groups examining a hydrogen economy are secure in the belief that H2 is a pure fuel, safe and harmless to the environment. A thorough well-to-wheel analysis as envisaged by the NAS report is needed to evaluate the environmental costs/benefits of a hydrogen economy (e.g., the energy source for producing H2, the distribution system), but it needs also to include our knowledge of the biogeochemical cycling of H2 in the atmosphere (0.5 ppm or about 175 Tg) and how it might be perturbed. This brief review of the science examines what controls the atmospheric abundance of H2 and how the chemistry of H2 impacts the climate and global air quality. Recent work on hydrogen isotopes, global modeling of sources and sinks, and the stratospheric and climate connections, enables us to more clearly define the budget and impacts of H2, and to place reasonable bounds on the environmental impacts - provided we understand the possible future emissions of H2 and of related direct and indirect greenhouse gases.

    2004-02-01

    Previous analyses of a large ensemble of stock markets have demonstrated that a log-periodic power law (LPPL) behavior of the prices constitutes a qualifying signature of speculative bubbles that often land with a crash. We detect such a LPPL signature in the foreign capital inflow during the bubble on the US markets culminating in March 2000. We detect a weak synchronization and lag with the NASDAQ LPPL pattern. We propose to rationalize these observations by the existence of positive feedback loops between market-appreciation/increased-spending/increased-deficit-of-balance-of-payment/larger-foreign-surplus/increased-foreign-capital-inflows and so on. Our analysis suggests that foreign capital inflow has been following rather than causing the bubble. We then combine a macroeconomic analysis of feedback processes occurring between the economy and the stock market with a technical analysis of more than 200 years of the DJIA to investigate possible scenarios for the future, three years after the end of the bubble and deep into a bearish regime. We conclude that the low interest rates and depreciating dollar are the indispensable ingredients for a lower sustainable burden of the global US debt structure and for allowing the slow rebuilding of an internationally competitive economy. This will probably be accompanied by a weak stock market on the medium term as the growing Federal deficit is consuming a large part of the foreign surplus dollars and the stock market is remaining a very risky and unattractive investment. Notwithstanding strong surge of liquidity in recent months orchestrated by the Federal Reserve, this macroeconomic analysis which incorporates an element of collective behavior is in line with our recent analyses of the bearish market that started in 2000 in terms of a LPPL “anti-bubble”. We project this LPPL anti-bubble to continue at least for another year. On the short term, increased availability of liquidity (M1) and self-fulfilling bullish anticipations may hold the stock market for a while.

  13. Energy demand in Jordan: a case study of energy-economy linkages

    A case study based on Jordan illustrates the application of existing methods of economy-wide modeling to the analysis of energy-economy interactions for a country with nearly total dependence on imported oil. The model focuses on the links between medium-term growth and energy prices, broad investment allocation decisions, and consistent energy demand projections. Key policy variables are domestic energy prices and subsidies, sectoral investment allocations, and foreign borrowing. The results indicate that energy demand is likely to increase as much as 25% faster than gross domestic product. The model shows that the effect of energy subsidies on demand growth are substantial, and that Jordan would be worse off with constant world prices and continued subsidies than with higher prices and no subsidies. 6 references, 7 tables.

    In earlier work performed for the DOE, EEA has analyzed technological trends in cars, light-duty trucks (LDT), and heavy-duty trucks (HDT). The technological analysis was used to forecast fuel economy for the three vehicle classes. In this report, EEA has updated both the methodology used to forecast fuel economy as well as the technological and tooling plan data central to the derivation of the forecast for all those vehicle classes. Forecasts were prepared for a scenario where oil prices stay flat through 1985 (in current real dollars) and increase at the rate of two % per year in the 1985 to 1995 period. This report also documents EEA's estimates of the mix of vehicles sold and projections for diesel penetration.

    Gait disturbances are frequent in Parkinson's disease (PD) and are associated with increased energy expenditure during walking. This study evaluated whether the effects of treadmill training are associated with an improvement of walking economy. Ten patients with idiopathic PD underwent treadmill training (30 min, three times a week for 4 weeks). Walking performance (Tauimed Up and Go, 6-min and 10-m walking tests) and metabolic function (oxygen uptake, heart and respiratory rate) were evaluated before training, at the end of treatment and after 30 days with two different graded exercises (treadmill and cycloergometer). Training significantly improved walking performance. Oxygen uptake, and heart and respiratory rates were significantly decreased only during graded exercise on the treadmill, but not on the cycloergometer. Treadmill training reduces energy expenditure during walking in PD, but the improvements of metabolic walking economy are associated with the specifically trained motor activity. PMID:19768366

    The underground economy has attracted a lot of attention recently as a key component of cybercrime. In particular the IRC markets for stolen identities, phishing kits, botnets, and cybercrime related services have been extensively studied. It is suggested that sophisticated underground markets show great specialization and maturity. There are complex divisions of labor and service offerings for every need. Stolen credentials are traded in bulk for pennies on the dollar. It is suggested that large sums move on these markets.

  19. Scales of mantle heterogeneity

    2004-12-01

    A long-standing question in mantle dynamics concerns the scale of heterogeneity in the mantle. Mantle convection tends to both destroy (through stirring) and create (through melt extraction and subduction) heterogeneity in bulk and trace element composition. Over time, these competing processes create variations in geochemical composition along mid-oceanic ridges and among oceanic islands, spanning a range of scales from extremely long wavelength (for example, the DUPAL anomaly) to very small scale (for example, variations amongst melt inclusions). While geochemical data and seismic observations can be used to constrain the length scales of mantle heterogeneity, dynamical mixing calculations can illustrate the processes and timescales involved in stirring and mixing. At the Summer 2004 CIDER workshop on Relating Geochemical and Seismological Heterogeneity in the Earth's Mantle, an interdisciplinary group evaluated scales of heterogeneity in the Earth's mantle using a combined analysis of geochemical data, seismological data and results of numerical models of mixing. We mined the PetDB database for isotopic data from glass and whole rock analyses for the Mid-Atlantic Ridge (MAR) and the East Pacific Rise (EPR), projecting them along the ridge length. We examined Sr isotope variability along the East Pacific rise by looking at the difference in Sr ratio between adjacent samples as a function of distance between the samples. The East Pacific Rise exhibits an overall bowl shape of normal MORB characteristics, with higher values in the higher latitudes (there is, however, an unfortunate gap in sampling, roughly 2000 km long). These background characteristics are punctuated with spikes in values at various locations, some, but not all of which are associated with off-axis volcanism. A Lomb-Scargle periodogram for unevenly spaced data was utilized to construct a power spectrum of the scale lengths of heterogeneity along both ridges. Using the same isotopic systems (Sr, Nd and Pb), we correlated isotopic data from oceanic islands and seamounts with geophysical measurements and observations in order to determine whether the mantle source component end-members are related to geophysical structure. For this, data obtained from the GeoROC database and other sources were first carefully examined for consistency and then correlated with recent global upper mantle tomographic models of seismic attenuation and velocity structure. Complementing this approach is a fractal analysis of dynamical models of mantle mixing. A variety of published numerical mixing models show a fractal distribution of heterogeneities, consistent with a marble-cake mantle.

  1. From oil shortage to oil glut: simulation of growth prospects in the Nigerian economy

    SciTech Connect

    Olofin, S.; Iyaniwura, J.O.

    1983-11-01

    During the 1970s, the economy of Nigeria provided one of the most interesting cases of development financed through oil revenue. Between 1970 and 1980, the country's GNP grew at an outstanding rate, but after the transition from oil shortage to oil glut, the economy of Nigeria ran into dramatic financial difficulties, which are now placing major constraints to its development. To investigate the transition from an oil-based economy to a stage characterized by greater diversification of exports and more balanced sectoral growth, a model has been built by the University of Ibadan in Nigeria. The model was developed in association with Project LINK staffing for the future inclusion in the Project. According to the finding presented in the study, the annual growth rate of GDP of Nigeria between 1980 and 1988 will be around 2.5%. To compensate the drop of the foreign-exchange earnings caused by the contraction of oil prices and demand, a vigorous export drive of agricultural products is simulated. 8 references, 7 figures, 4 tables.

    The globalized economy, fueled by late capitalism, has pressed forward its necessity for accumulation and expanding growth into the information and knowledge economy. One result has been the privatization of essentially public knowledge, knowledge produced at public universities, often with public, federal dollars. Both the "mania for ranking academic institutions," where universities compete for students, tuition dollars, and external funding, and the incessant creep of the managerial "audit culture" contribute to this situation. Although there is little individual scholars can do to resist globalization and capitalist forces, understanding the context into which their research is circulated can suggest opportunities for sharing research results between the "center" and "periphery" that counter some of the privatization trends.

    The Advanced Vehicle Testing Activity (AVTA), part of the U.S. Department of Energy’s FreedomCAR and Vehicle Technologies Program, has conducted testing of advanced technology vehicles since August, 1995 in support of the AVTA goal to provide benchmark data for technology modeling, and research and development programs. The AVTA has tested over 200 advanced technology vehicles including full size electric vehicles, urban electric vehicles, neighborhood electric vehicles, and hydrogen internal combustion engine powered vehicles. Currently, the AVTA is conducting significant tests of hybrid electric vehicles (HEV). This testing has included all HEVs produced by major automotive manufacturers and spans over 1.3 million miles. The results of all testing are posted on the AVTA web page maintained by the Idaho National Laboratory. Through the course of this testing, the fuel economy of HEV fleets has been monitored and analyzed to determine the "real world" performance of their hybrid energy systems, particularly the battery. While the initial "real world" fuel economy of these vehicles has typically been less than that evaluated by the manufacturer and varies significantly with environmental conditions, the fuel economy and, therefore, battery performance, has remained stable over vehicle life (160,000 miles).

  5. HIV and the moral economy of survival in an East African City.

    PubMed

    Prince, Ruth

    2012-12-01

    Based on fieldwork in the city of Kisumu, Kenya, the article examines the survival of HIV-positive people on antiretroviral (ARV) medicines and situates this within broader moral economies of their lives-in matters of food, hunger, social relationships, and networks of care, including NGOs. Through locating survival at the level of individual adherence to medication, ARV programs medicalize it. Yet their focus on the intimate relation between medicine and food also opens up spaces in which the material conditions of life can be articulated. The article follows these spaces, from the clinic to the economy of NGO interventions and community-based groups, paying attention to how hunger and material needs are visible in some spaces and invisible in others, and to how people have learned to articulate their "needs." In this economy, HIV identities accrue moral and economic value, as through them people become visible to the flow of funds and the distribution of goods organized by NGOs. PMID:23361884

  6. Hydrogen economy for a sustainable development: state-of-the-art and technological perspectives

    NASA Astrophysics Data System (ADS)

    Conte, M.; Iacobazzi, A.; Ronchetti, M.; Vellone, R.

    Sustainable energy is becoming of increasing concern world-wide. The rapid growth of global climate changes along with the fear of energy supply shortage is creating a large consensus about the potential benefits of a hydrogen economy coming from renewable energy sources. The interesting perspectives are over-shadowed by uncertainties about the development of key technologies, such as renewable energy sources, advanced production processes, fuel cells, metal hydrides, nanostructures, standards and codes, and so on. The availability of critical technologies can create a base for the start of the hydrogen economy, as a fuel and energy carrier alternative to the current fossil resources. This paper will explore the rationale for such a revolution in the energy sector, will describe the state-of-the-art of major related technologies (fuel cell, storage systems, fuel cell vehicles) and current niche applications, and will sketch scientific and technological challenges and recommendations for research and development (R&D) initiatives to accelerate the pace for the widespread introduction of a hydrogen economy.

  11. Monetary policy and the effects of oil price shocks on the Japanese economy

    Lee, Byung Rhae

    1998-12-01

    The evidence of output decreases and price level increases following oil price shocks in the Japanese economy is presented in this paper. These negative effects of oil shocks are better explained by Hamilton's (1996) net oil price increase measure (NOPI) than by other oil measures. The fact that an oil shock has a statistically significant effect on the call money rate and real output and that the call money rate also has a statistically significant effect on real output appears to explain that the effects of oil price shocks on economic activity are partially attributed to contractionary monetary policy responses. The asymmetric effects of positive and negative oil shocks are also found in the Japanese economy and this asymmetry can also be partially explained by monetary policy responses. To assess the relative contribution of oil shocks and endogenous monetary policy responses to the economic downturns, I shut off the responses of the call money rate to oil shocks utilizing the impulse response results from the VAR model. Then, I re-run the VAR with the adjusted call money rate series. The empirical results show that around 30--40% of the negative effects of oil price shocks on the Japanese economy can be accounted for by oil shock induced monetary tightening.

  2. International migration and the "moral" economy of the "Barani" peasantry.

    PubMed

    Khan, A F

    1991-01-01

    International migration and the "barani" peasantry are explained in terms of a subsistence ethic in rainfed agricultural areas of northern Pakistan. It is postulated that economic decisions of the "barani" are rational and are part of a willed order which reflects the economic, political, social and cultural aspects of a deliberately organized style of living. This functional structure is discussed in terms of the motivational concerns of the "biraderi" and the kinship and worksharing patterns and the household structure. There is selectivity in the migration pattern and the decision is made with the collective welfare of the household in mind. The migrant profile is one of single, young males about 24-35 years; most fall in the 26-32 age group. 67% are unmarried, but there is motivation to marry in order to make claims on fathers' lands and fulfill dowry payments and become more marriageable. Also, villagers desire to expand the number of "biraderi" which strengthens the socioeconomic foundation. Marriage is also related to earning potential. The migration impact is felt in terms of the absence, which results in a loss of labor, but usually households cope effectively. Another impact was one of remittances, which make a considerable difference in household income. From a sample of households taken in 1980-1984, over 65% of migrant households received over 75% of their income from migrant labor. Only 1 household received 50% of their income from migrant labor. It is estimated that 64% of annual migrant's earnings and 87% of migrant's savings were remitted. The impact was also felt in the use of remittances, which in order to importance, satisfied the needs of the households, their aspirations, and access to investment opportunities. A significant portion of income was spent on basic needs: food, clothing/footwear, and other related items, and health. A portion also went to savings. This occurred in order to achieve security and a measure of control over their lives. In poorer households, satisfaction of basic needs and a threshold of savings took precedence over housing improvements. Priorities were established. Security is achieved eventually in the investment in housing since most poor households lived in mud and straw ("kutcha") or bricks and cement ("pukka") prior to migration. These structures needed repair after the monsoons. Respectability is attained through purchase of land, and most desire this end. Access is limited however due to unavailability and high prices. Social standing is also attained through spending on marriages, hospitality, deaths, pilgrimages, and cultural feasts. Acquisition of consumer durables is associated with a higher socioeconomic profile and occurs mostly among the better off. Poor migrants purchase these items for resale. Land investments were made for development of rent yielding commercial plots. PMID:12285302

    Cultural industry is one of the fastest growing industries and the added value of culture industry is almost more than 10% of GDP in developed countries. This paper first introduced the boundaries of cultural industries and the development of that in Tianjin. Then the logistic growth model was used to detect the stage of the life cycle of culture industry in Tianjin. We draw the conclusion that culture industry is in the rapid growth stage in Tianjin, and we must take scientific development, increasing innovation through structural reform, technological advances, personnel training and other measures to promote the cultural industry development in Tianjin by leaps.

    PubMed

    Chossudovsky, M

    1983-01-01

    This article applies Marx's abstract subdivision of social consumption to the prevailing patterns of capital accumulation in the Third World. Built-in scarcities in the availability of necessary consumer goods, alongside patterns of overconsumption and social waste by the upper-income groups, are conducive to conditions of mass poverty, malnutrition, and disease that coexist with small pockets of social privilege and affluence. Malnutrition and ill health must be understood and analyzed in relation to the dual and divided structure of social consumption: necessities of life as opposed to luxury and semi-luxury goods. The relationship between capital accumulation, the distribution of money income, and patterns of malnutrition and ill health is analyzed. It is shown that patterns of malnutrition and ill health are socially differentiated, and the core disease pattern in Third World social formations is discussed in relation to the material and social conditions of life which generate ill health and which underlie particular patterns of peripheral capital accumulation. The study focuses on empirical procedures for analyzing the relationship between levels of money income and levels of calorie and protein intake. An appendix outlines a methodology for estimating undernourishment in urban areas from household budget surveys. PMID:6832875

  10. Quantity vs quality of oil: Implications for the future economy

    NASA Astrophysics Data System (ADS)

    Hall, C.

    2012-12-01

    There has considerable interest recently in various indications of important changes in the technology of oil production and its impact on US oil production. The data indicate a clear increase in oil production for the US after 40 years of year by year decline. This has led some commentators to predict that the US will become a net oil exporter before long. Maps showing the enormous extent of e.g. the Bakken formation in North Dakota and Montana, and our ability to now exploit this oil using the new techniques of horizontal drilling and fracking, gives the impression that there are enormous new oil reserves that can satisfy our wants indefinitely. Other assessments indicate that the amount of oil still available globally is 3, 4 or more times the usual assessments of about 1 trillion barrels. But "oil" is not a single substance, but rather a suite of materials of widely varying qualities and hence utility. One important index is the energy return on investment (EROI), the ratio of energy returned from energy used to get it. EROI reflects the balance of the countervailing impacts of depletion and technology and ultimately determines the price of a fuel. This ratio is declining all around the world, and gives a practical limit to how much oil we can exploit at an energy and economic profit. Bringing quality of oil into the equation gives a much more restrictive estimate of how much oil we are likely to be able to exploit for fuel.

    This paper examines the extent to which agglomeration of the hospital service industry enhances the productivity of producing health care. Specifically, we use a large set of private insurance claims from the FAIR Health database to show that an increasing spatial concentration of hospital services results in a decreased cost of obtaining intermediate medical services. We explicitly test whether the reduced cost at concentrated locations arises from the ability to share intermediate service providers. The identification relies on state variation in medical lab technician licensure requirements, which influence the cost of intermediate services only through the cost of running a lab. Our findings suggest that agglomeration of the hospital service industry attracts specialized medical labs, which in turn help to reduce the cost of producing laboratory tests. PMID:26642802

  12. Molecular economy and antibody function: the evolution of a Protecton.

    The humoral immune response protects against a very large array of pathogens which attempt to escape immune recognition by changing the antigens they display. When looked at from the point of two competing sets of DNA (i.e., the pathogens vs. the host), there is a vastly larger pool of mutating pathogen DNA than in, say, a mouse. The stratagems that allow a tiny fraction of the mouse's genome to effectively compete with a hugely diverse array of pathogens is analyzed in terms of how antibody functions and how the immune system avoids such pitfalls as self-recognition and destruction. This review is a more general description of a lengthy series of papers which detailed the evolution of the Protecton. Starting from the obvious, that is the concentration-dependence of antibody function, it is apparent that the functional antibody repertoire must be relatively small if a sufficient concentration of specific antibody is to be produced in time to arrest the growth of pathogens and eventually eliminate them. Thus, commonly quoted estimates of antibody repertoires in the range from greater than 10(10) to "complete" (infinite?) must be seriously in error. Other well known "facts", such as D-diversity, and B cell signaling by receptor aggregation are also shown to be lacking in biological commonsense. PMID:1504307

    Inroads made by the colonial rule on western medicine continue to influence health services systems in 3rd World countries to this day. While half-hearted efforts have been made to overcome the adverse effects of such influence, they have not proved very successful. This is so largely because of the nature of the political systems and social structures prevailing in many of the 3rd World countries that have placed at the helm of affairs a political leadership not capable of severing its links with western conceptualization, development, and delivery of health care services systems. However, due to various factors (most important being the rising political consciousness among people) the inequitous sociopolitical system has conceded to a people-oriented health services system. The degree of political commitment to this goal will determine the level of success it is able to achieve. The degree of political commitment depends on the degree of mobilization of people. The struggle for health thus becomes a struggle for democratization. In this struggle for democratization, alleviation of suffering due to health problems becomes a political device for community mobilization. Once this is understood, it is the task of those involved in democratization to mobilize community health physicians to devise community-oriented health services. PMID:12179471

  14. Hyperincursion and the Globalization of the Knowledge-Based Economy

    In biological systems, the capacity of anticipation—that is, entertaining a model of the system within the system—can be considered as naturally given. Human languages enable psychological systems to construct and exchange mental models of themselves and their environments reflexively, that is, provide meaning to the events. At the level of the social system expectations can further be codified. When these codifications are functionally differentiated—like between market mechanisms and scientific research programs—the potential asynchronicity in the update among the subsystems provides room for a second anticipatory mechanism at the level of the transversal information exchange among differently codified meaning-processing subsystems. Interactions between the two different anticipatory mechanisms (the transversal one and the one along the time axis in each subsystem) may lead to co-evolutions and stabilization of expectations along trajectories. The wider horizon of knowledgeable expectations can be expected to meta-stabilize and also globalize a previously stabilized configuration of expectations against the axis of time. While stabilization can be considered as consequences of interaction and aggregation among incursive formulations of the logistic equation, globalization can be modeled using the hyperincursive formulation of this equation. The knowledge-based subdynamic at the global level which thus emerges, enables historical agents to inform the reconstruction of previous states and to co-construct future states of the social system, for example, in a techno-economic co-evolution.

    The authors examine the possibility of reducing steam consumption for vulcanizing tires in the multistation tire vulcanizer (MTV) lines by improving the thermal insulation of the steam chamber. The layout of the experimental unit is shown. Several types of chamber designs were studied. Test results show that when using shells and replacing metallic by glass textolite hoods, the temperature on the inner and outer surfaces of the chamber vary insignificantly. When using the shell, the temperature of the bayonet ring increases and promotes reduced thermal stresses in the system bayonet-ring-chamber, improving operating conditions.

    Abstract In the wake of avian flu outbreaks in 2004, Cambodia received $45 million in commitments from international donors to help combat the spread of animal and human influenza, particularly avian influenza (H5N1). How countries leverage foreign aid to address the specific needs of donors and the endemic needs of the nation is a complex and nuanced issue throughout the developing world. Cambodia is a particularly compelling study in pandemic preparedness and the management of avian influenza because of its multilayered network of competing local, national, and global needs, and because the level of aid in Cambodia represents approximately $2.65 million per human case-a disproportionately high number when compared with neighbors Vietnam and Indonesia. This paper examines how the Cambodian government has made use of animal and human influenza funds to protect (or fail to protect) its citizens and the global community. It asks how effective donor and government responses were to combating avian influenza in Cambodia, and what improvements could be made at the local and international level to help prepare for and respond to future outbreaks. Based on original interviews, a field survey of policy stakeholders, and detailed examination of Cambodia's health infrastructure and policies, the findings illustrate that while pandemic preparedness has shown improvements since 2004, new outbreaks and human fatalities accelerated in 2011, and more work needs to be done to align the specific goals of funders with the endemic needs of developing nations.

    Anaerobic digestion is the default process for biological conversion of residue organics to renewable energy and biofuel in the form of methane. However, its scope of application is expanding, due to availability of new technologies, and the emerging drivers of energy and nutrient conservation and recovery. Here, we outline two of these new application areas, namely wastewater nutrient and energy recovery, and generation of value added chemicals through mixed culture biotechnology. There exist two options for nutrient and energy recovery from domestic wastewater: low energy mainline and partition-release-recovery. Both are heavily dependent on anaerobic digestion as an energy generating and nutrient release step, and have been enabled by new technologies such as low emission anaerobic membrane processes. The area of mixed culture biotechnology has been previously identified as a key industrial opportunity, but is now moving closer to application due application of existing and new technologies. As well as acting as a core technology option in bioproduction, anaerobic digestion has a key role in residual waste valorization and generation of energy for downstream processing. These new application areas and technologies are emerging simultaneously with substantial advances in knowledge of underlying mechanisms such as electron transfer, understanding of which is critical to development of the new application areas.
