Sample records for economies of scale

  1. Supergroups and economies of scale.

    2009-02-01

    With the changing environment for medical practice, physician practice models will continue to evolve. These "supergoups'' create economies of scale, but their advantage is not only in the traditional economic sense. Practices with enough size are able to better meet the challenges of medical practice with increasing regulatory demands, explosion of clinical knowledge, quality and information technology initiatives, and an increasingly tight labor market. Smaller practices can adapt some of these strategies selectively. Depending on the topic, smaller practices should think differently about how to approach the challenges of practice.

  5. Economies of scale in home care.

    PubMed

    Joffe, J

    1989-01-01

    Home care (HC) demonstration projects have assessed the results of an existing decentralized system rather than evaluate the consequences of changing the system. This paper examines the potential for improving HC cost performance through economies of scale and how these economies can be introduced into HC operations with expansion and consolidation of the market. Theoretical, empirical and policy issues discussed include: (a) specification of the elements of structural redesign of HC service programs focusing on the creation of joint services; (b) a critique of the current method of estimating the size of the market for long term care; (c) empirical measures of uneven HC market size and density with implications for the opportunity to apply economies of scale; (d) the major institutional obstacles to creating the requisite coordination for joint HC services and policy recommendations to overcome these obstacles; (e) housing settings for joint services; (f) HC practices embodying economies of scale in Sweden. Joint services are especially applicable in older northern cities with a high density and a large number of elderly persons. This delivery mode provides a cost savings logic for expanding and consolidating home care services.

    2004-07-01

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

    PubMed

    Valdmanis, Vivian G

    2010-01-01

    Data envelopment analysis (DEA) techniques have been applied to the assessing efficiency and productivity among individual hospitals. In this article, we employ DEA to address whether economies of scale exist among hospital markets by first assessing individual hospitals operating in 2005 in the State of Florida and then by comparing hospital markets' efficiency relative to each other. The interest in hospital markets stems from issues relating to mergers among hospitals or the reallocation of services (inputs) among hospitals in a market area, particularly as occupancy rates and reimbursements are tending to fall. Facing more competition and stringent financial conditions, hospitals would benefit from decreasing costs by exploiting economies of scale.

    We discuss linear Ricardo models with a range of parameters. We show that the exact boundary of the region of equilibria of these models is obtained by solving a simple integer programming problem. We show that there is also an exact correspondence between many of the equilibria resulting from families of linear models and the multiple equilibria of economies of scale models.

  15. The economies of scale for nursing home care.

    PubMed

    Chen, Li-Wu; Shea, Dennis G

    2004-03-01

    Using a modified hybrid short-term operating cost function and a national sample of nursing homes in 1994, the authors examined the scale economies of nursing home care. The results show that scale economies exist for Medicare postacute care, with an elasticity of -0.15 and an optimal scale of around 4,000 patient days annually. However, more than 68 percent of nursing homes in the analytic sample produced Medicare days at a level below the optimal scale. The financial pressures resulting from the implementation of a prospective payment system for Medicare skilled nursing facilities may further reduce the quantity of Medicare days served by nursing homes. In addition, the results show that chain-owned nursing homes do not have lower short-term operating costs than do independent facilities. This indicates that the rationale behind recent increasing horizontal integration among nursing homes may not be seeking greater cost efficiency but some other consideration.

  1. Factors affecting economies of scale in combined sewer systems.

    PubMed

    Maurer, Max; Wolfram, Martin; Anja, Herlyn

    2010-01-01

    A generic model is introduced that represents the combined sewer infrastructure of a settlement quantitatively. A catchment area module first calculates the length and size distribution of the required sewer pipes on the basis of rain patterns, housing densities and area size. These results are fed into the sewer-cost module in order to estimate the combined sewer costs of the entire catchment area. A detailed analysis of the relevant input parameters for Swiss settlements is used to identify the influence of size on costs. The simulation results confirm that an economy of scale exists for combined sewer systems. This is the result of two main opposing cost factors: (i) increased construction costs for larger sewer systems due to larger pipes and increased rain runoff in larger settlements, and (ii) lower costs due to higher population and building densities in larger towns. In Switzerland, the more or less organically grown settlement structures and limited land availability emphasise the second factor to show an apparent economy of scale. This modelling approach proved to be a powerful tool for understanding the underlying factors affecting the cost structure for water infrastructures.

  2. Estimating unbiased economies of scale of HIV prevention projects: a case study of Avahan.

    Lépine, Aurélia; Vassall, Anna; Chandrashekar, Sudha; Blanc, Elodie; Le Nestour, Alexis

    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.

    1985-01-01

    The Health Care Financing Administration has demonstrated an interest in the economies of scale phenomenon as it might apply to reimbursement methodologies. This paper provides a critical evaluation of the economies of scale research methodology and a critical review of both the analytical (LRAC estimates) and the implied economies of scale (spreading fixed costs) literature. Given that estimates of Minimum Optimum Scale are based on individual coefficients generated by a regression model, this work illustrates the danger inherent in this approach and examines the volatility of the coefficient values and their dependence upon model specification. The ambiguity present in the literature addressing the LRAC estimates is thereby explained. An evaluation of the implied economies of scale literature reveals that average fixed costs decrease with increasing levels of output. This should not be a surprise to anyone. The notion of economies of scale is implied in this literature but never addressed. It is suggested in this work that the means to better standardize the output of the hospital industry, the sine qua non of economies of scale research, is now available in various methodologies of patient grouping.

    2000-01-01

    The Cobb-Douglas production function was used to empirically estimate whether or not larger hospitals have lower long-run average costs per bed than smaller hospitals. The results indicate that economies of scale have evolved recently for non-teaching and teaching hospitals. It is believed that the primary market forces that may be creating economies of scale in the hospital industry are decreasing revenues due to lower reimbursement and lower occupancy rates. As reimbursement and occupancy continue to trend down in the future, hospitals may seek additional economies to survive in an increasingly competitive and shrinking industry.

  9. Economies of scale in non-revenue producing cost centers: implications for hospital mergers.

    PubMed

    Dranove, D

    1998-01-01

    This paper uses semiparametric methods to estimate the magnitude of economies of scale in 14 non-revenue producing cost centers in hospitals. There are substantial economies of scale in small hospitals, but economies are exhausted in hospitals with over 10,000 discharges annually. In recent hospital mergers challenged by federal antitrust agencies, one or both hospitals had over 10,000 discharges, suggesting that efficiency gains in non-revenue producing cost centers will be small, and could easily be offset by nominal price increases.

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

    Hoess, Victoria; Bachler, Adi; Ostermann, Herwig; Staudinger, Roland

    2009-01-01

    The call to enlarge or merge nursing homes in order to lower costs rests on the assumption that economies of scale exist within the cost structure of these homes. Economies of scale means that an increasing number of residents will reduce the costs per person needing care. However, the existence and the extent of economies of scale as such in nursing homes are the subject of controversy because studies of this issue performed in nursing homes up to now have yielded contradictory results. In this study, researchers demonstrated economies of scale in Tyrolean, Austria, nursing homes and showed that the composition of the nursing home residents in respect to their care needs influences the development of the average costs. Changing the size of the facility and/or influencing the average care level can have a considerable influence on the progression of average costs in nursing homes. Cost reductions can be achieved by increasing the size of the facility or by improved distribution of the care levels of the persons in need of care.

    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.

  18. Multispecialty physician practices: fixed and variable costs, and economies of scale.

    PubMed

    Weil, Thomas P

    2002-07-01

    Medical Group Management Association survey data from 1955 to 1999 was to assess fixed compared to variable cost and the existence of economies of scale among single- and multispecialty groups. During these intervening 44 years, physician operating costs were estimated to increase roughly three times the consumer price index. Among the multispecialty groups in 1999 at least 85% of total medical revenues were considered fixed costs when including a physician's compensation and fringe benefits. On the basis of relative value units (RVUs), 10 practitioners provided the maximum economies of scale. However, for multispecialty groups, based on a physician's total compensation, optimal efficiency occurred between 26 and 50 doctors. Those multispecialty practices with 51 or more MDs are thought to be "less efficient" for several reasons: they deliver care on multisites, experience a higher percentage of managed care patients, and are less effective in controlling their peers' use of time and resources.

    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.

    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.

    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.

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

    This paper presents a statistical analysis of the hypothesis that there are economies of scale in the collection of blood. Based on a national sample of Red Cross collection centers, an analysis was conducted to determine the relationship between total costs of obtaining blood as well as its recruitment and collection components, and explanatory factors such as local costs, mobile units used, and scale of operations. Adjusting for other factors, our results indicate slight diseconomies of scale at all levels of operation: that is, as scale of operations increase, collection costs rise. Only the costs associated with the recruitment and collection functions are examined in this study.

    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.

    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, ΦMB,packing, and the filling degree of the substrates with respect to the void volume of the milling balls' packing, ΦGS, 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 ΦMB,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 ΦGS 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.

    We examine scale and scope economics among Group and IPA Health Maintenance Organizations (HMOs) over the period 1988 to 1991 using a national sample of HMOs. We allow for the multiproduct nature of HMO production by estimating the cost of producing a member month of non-Medicare and Medicare coverage, and we examine the effect of HMO market structure on costs. We find that HMOs benefit from scale economies. There are scope diseconomies associated with providing both non-Medicare and Medicare products. Group HMOs in more competitive markets have lower costs but IPA costs are not affected by competition.

  14. Scale and scope economies in nursing homes: a quantile regression approach.

    2004-04-01

    Nursing homes vary widely between facilities with very few beds and facilities with several hundred beds. Previous studies, which estimate nursing home scale and scope economies, do not account for this heterogeneity and implicitly assume that all nursing homes face the same cost structure. To account for heterogeneity, this paper uses quantile regression to estimate cost functions for skilled and intermediate care nursing homes. The results show that the parameters of nursing home cost functions vary significantly by output mix and across the cost distribution. Estimates show that product-specific scale economies systematically increase across the cost distribution for both skilled and intermediate care facilities, with diseconomies of scale in the lower deciles and no significant scale economies in the higher deciles. As for ray scale economies, estimates show economies of scale in the lower deciles and diseconomies of scale or no significant scale economies at higher deciles. The estimates also show that scope economies exist in the lower cost deciles and that no scope economies exist in the higher cost deciles. Additionally, the degree of scope economies monotonically decreases across the deciles.

    This study investigates the existence of economies of scale in the provision of breast and cervical cancer screening and diagnostic services by state National Breast and Cervical Cancer Early Detection Program (NBCCEDP) grantees. A translog cost function is estimated as a system with input factor share equations. The estimated cost function is then used to determine output levels for which average costs are decreasing (i.e., economies of scale exist). Data were collected from all state NBCCEDP programs and District of Columbia for program years 2006-2007, 2008-2009 and 2009-2010 (N = 147). Costs included all programmatic and in-kind contributions from federal and non-federal sources, allocated to breast and cervical cancer screening activities. Output was measured by women served, women screened and cancers detected, separately by breast and cervical services for each measure. Inputs included labor, rent and utilities, clinical services, and quasi-fixed factors (e.g., percent of women eligible for screening by the NBCCEDP). 144 out of 147 program-years demonstrated significant economies of scale for women served and women screened; 136 out of 145 program-years displayed significant economies of scale for cancers detected. The cost data were self-reported by the NBCCEDP State programs. Quasi-fixed inputs were allowed to affect costs but not economies of scale or the share equations. The main analysis accounted for clustering of observations within State programs, but it did not make full use of the panel data. The average cost of providing breast and cervical cancer screening services decreases as the number of women screened and served increases.

    As administrators, we continually strive to compare our group's performance to accepted standards of cost and production. In making comparisons to national norms, it is important to understand the statistical sample of groups from which these norms are drawn. Therefore, differentiations in the size of a group alone may have predisposed a group to either favorable or unfavorable comparisons to national standards. This professional paper was written in order to investigate the relationship between group size and measures of performance.

    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.

    Diagnosis Related Group (DRG) hospital payment has begun to squeeze hospitals financially and is likely to do so in the future. This study analyzed the relationship between the volume of urologic procedures by an individual urologist, hospital costs per patient, and outcome. We used a three-year DRG database of urology patients (N = 2,980) at an academic medical center to analyze these. Low-volume urologists (arbitrarily defined by us) had higher hospital costs per patient, financial losses versus profits under DRGs, and a poorer outcome when compared with high-volume urologists. Pearson correlation showed a positive relationship between cost per patient and physician volume for nonemergency patients (-0.129, p less than 0.0001) and emergency patients (-0.368, p less than 0.0001). This may have been explained (in part) by a greater severity of illness for patients of low-volume urologists. These findings suggest, however, that the volume of urologic procedures per urologist may be related to hospital resource consumption. The health care financing environment of the future should provide substantial interest in this finding for those involved in the consumption of urologic services.

    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.

    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.

    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.

  11. Economies of Size in Production Agriculture.

    PubMed

    Duffy, Michael

    2009-07-01

    Economies of size refer to the ability of a farm to lower costs of production by increasing production. Agriculture production displays an L-shaped average cost curve where costs are lower initially but reach a point where no further gains are achieved. Spreading fixed costs, bulk purchases, and marketing power are cited as reasons for economies of size. Labor-reducing technologies may be the primary reason. Most studies do not include the external costs from prophylactic antibiotic use, impact on rural communities, and environmental damage associated with large-scale production. These can contribute to the economies of size.

    Using the most detailed and recent statistics available for Beijing, a local-scale embodiment analysis on water use was conducted, employing a systems input-output analysis that integrates economic systems with natural resources data. Systems analysis for water research at the local scale is a crucial part of a systems oriented water accounting framework. To our knowledge, however, related works have not been thoroughly conducted. In this paper, a set of embodied water intensity inventory data is presented, which is applicable to both intermediate input and final demand. Also, detailed analyses of Beijing's embodied water use accounting are presented. The embodied water intensity of the Water Production and Supply Industry Sector turns out to be the highest among the 42 sectors. For water embodied in final demand, the total amount is 3.48 km3, of which the water embodied in urban household consumption makes up nearly a half proportion. As a net virtual water importer, Beijing's water embodied in commodity trade totals 5.84×108 m3. As a result, in addition to improvements in technology and water use efficiency, adjustments in industrial structure and trade policies are also of significant importance to water conservation efforts.

    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.

  15. The symbolic economy of drugs.

    Lentacker, Antoine

    2016-02-01

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

  17. The changing political economy of sex in South Africa: the significance of unemployment and inequalities to the scale of the AIDS pandemic.

    PubMed

    Hunter, Mark

    2007-02-01

    Between 1990 and 2005, HIV prevalence rates in South Africa jumped from less than 1% to around 29%. Important scholarship has demonstrated how racialized structures entrenched by colonialism and apartheid set the scene for the rapid unfolding of the AIDS pandemic, like other causes of ill-health before it. Of particular relevance is the legacy of circular male-migration, an institution that for much of the 20th century helped to propel the transmission of sexually transmitted infections among black South Africans denied permanent urban residence. But while the deep-rooted antecedents of AIDS have been noted, less attention has been given to more recent changes in the political economy of sex, including those resulting from the post-apartheid government's adoption of broadly neo-liberal policies. As an unintentional consequence, male migration and apartheid can be seen as almost inevitably resulting in AIDS, a view that can disconnect the pandemic from contemporary social and economic debates. Combining ethnographic, historical, and demographic approaches, and focusing on sexuality in the late apartheid and early post-apartheid periods, this article outlines three interlinked dynamics critical to understanding the scale of the AIDS pandemic: (1) rising unemployment and social inequalities that leave some groups, especially poor women, extremely vulnerable; (2) greatly reduced marital rates and the subsequent increase of one person households; and (3) rising levels of women's migration, especially through circular movements between rural areas and informal settlements/urban areas. As a window into these changes, the article gives primary attention to the country's burgeoning informal settlements--spaces in which HIV rates are reported to be twice the national average--and to connections between poverty and money/sex exchanges.

    PubMed

    Mehta, S; Mehta, H S

    1987-01-01

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

  7. Networked incubators. Hothouses of the new economy.

    PubMed

    2000-01-01

    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.

  11. Fuel economy of hydrogen fuel cell vehicles

    NASA Astrophysics Data System (ADS)

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

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

    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.

  1. Economics of automobile fuel-economy standards

    SciTech Connect

    Kleit, A.N.

    1987-01-01

    Since 1978 the Federal government has mandated that new automobiles sold by major firms in the United States reach certain levels of average fuel efficiency. Corporate Average Fuel Economy (CAFE) standards can generate implicit taxes and subsidies for various types of cars. They also can have an impact on market structure, creating regulatory economies of scope. CAFE standards may also act to increase the profits of firms in the automobile industry, either by preventing competition among firms constrained by the standards or by creating profit opportunities for firms not constrained by the standards. CAFE standards are shown to have had a significant effect on the price of new cars in model years 1983 through 1986, raising the price of fuel inefficient cars and lowering the price of fuel efficient cars. The gasoline savings resulting from the imposition of higher standards are computed, as well as the welfare loss they generate. It is concluded that automobile fuel economy standards can save gasoline,but only at a large loss to the economy. An empirical model of the political support for CAFE standards is developed and tested. It is shown that support for the standards comes from the one major domestic automobile company that would benefit from higher standards, as well as from those who in general prefer regulatory solutions to the free market.

    Homeless youth (HY) who lack employment in the formal economy typically turn to the street economy (e.g., prostitution, drug selling) for survival. Guided by the theory of social control, the present paper explores factors influencing HY's initiation into the street economy. Eighty HY (ages 15-23) were recruited from four community-based organizations. All participated in structured interviews and 25% participated in qualitative interviews. Almost all HY had participated in the street (81%) and formal economies (69%). Five main factors simultaneously influenced initiation into the street economy: social control/bonds, barriers to the formal economy (e.g., homelessness, educational deficits, mental health problems, incarceration, stigma), tangible and social/emotional benefits of the street economy, severe economic need, and the active recruitment of HY into the street economy by others. Qualitative and quantitative data sources were congruent. Intervention efforts are needed at multiple levels of influence to promote HY's success in the formal economy.

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.

    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.

    2001-01-01

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

  10. 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.

  1. Pakistan: social basis of the economy.

    PubMed

    Maloney, C

    1987-01-01

    Pakistan's gross domestic product (GDP) has grown at an average of 5.3%/year since 1950 and real per capita income has increased 3.7%/year over the past decade, despite a 3% annual population growth rate. Contributing to this dynamic economic growth have been migration, the construction of a new national economy following independence, controlled irrigation, foreign exchange availability, and an expectation on the part of the public of higher earnings and consumption. Despite these trends, the Pakistan economy is structurally weak and there have been rapid increases in both the domestic and foreign debt. Economic growth has been based largely on trading and soft services. Government departments are known for their corruption. This self-contradictory economic picture derives directly from the structure of Pakistani society, which is dominated by the elite of Punjab Province. Urbanization is increasing economic inequality in the society, and government taxation policies are biased toward big agriculture and industry. Pakistan's poor performance in education, social development, and family planning are expected to inhibit future economic development. Only 26% of Pakistanis are literate, reflecting the low social value placed on education. Even in urban areas, there is no evidence of a decline in fertility. This results from the psychological and economic need for children, women's limited roles, Islamic opposition to family planning, and inefficient government delivery of social services. Within a few years, population growth will magnify the structural weaknesses of the Pakistan economy. It is hoped that the dynamic nature of Panjabi values and behavior, especially of the new middle class, will lead to a redress of this situation.

    Reuter, Markus A.

    2016-09-01

    Metallurgy is a key enabler of a circular economy (CE), its digitalization is the metallurgical Internet of Things (m-IoT). In short: Metallurgy is at the heart of a CE, as metals all have strong intrinsic recycling potentials. Process metallurgy, as a key enabler for a CE, will help much to deliver its goals. The first-principles models of process engineering help quantify the resource efficiency (RE) of the CE system, connecting all stakeholders via digitalization. This provides well-argued and first-principles environmental information to empower a tax paying consumer society, policy, legislators, and environmentalists. It provides the details of capital expenditure and operational expenditure estimates. Through this path, the opportunities and limits of a CE, recycling, and its technology can be estimated. The true boundaries of sustainability can be determined in addition to the techno-economic evaluation of RE. The integration of metallurgical reactor technology and systems digitally, not only on one site but linking different sites globally via hardware, is the basis for describing CE systems as dynamic feedback control loops, i.e., the m-IoT. It is the linkage of the global carrier metallurgical processing system infrastructure that maximizes the recovery of all minor and technology elements in its associated refining metallurgical infrastructure. This will be illustrated through the following: (1) System optimization models for multimetal metallurgical processing. These map large-scale m-IoT systems linked to computer-aided design tools of the original equipment manufacturers and then establish a recycling index through the quantification of RE. (2) Reactor optimization and industrial system solutions to realize the "CE (within a) Corporation—CEC," realizing the CE of society. (3) Real-time measurement of ore and scrap properties in intelligent plant structures, linked to the modeling, simulation, and optimization of industrial extractive process

  8. The impact of health on Kentucky's economy.

    Anderson, Danielle; Asher, Linda M; Whitler, Elmer; Wilson, Emery A

    2008-07-01

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

  11. Stretched exponential distributions in nature and economy: ``fat tails'' with characteristic scales

    NASA Astrophysics Data System (ADS)

    Laherrère, J.; Sornette, D.

    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.

  14. 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.

  15. A proposal to extend our understanding of the global economy

    1991-01-01

    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.

    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.

  2. Assessment of California reformulated gasoline impact on vehicle fuel economy

    Aceves, S.; Glaser, R.; Richardson, J.

    1997-01-01

    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.

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

    SciTech Connect

    Haihua Zhao; Hongbin Zhang; Ling Zou

    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

    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.

    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

    This paper evaluates the short-term impact of Thailand's 'Million Baht Village Fund'program, among the largest scale government microfinance iniative in the world, using pre- and post-program panel data and quasi-experimental cross-village variation in credit-per-household. 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.

    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.

  20. 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

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

    PubMed

    Morris, Lydia

    2016-03-01

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

  3. The health effects of leaving school in a bad economy.

    PubMed

    Maclean, Johanna Catherine

    2013-09-01

    This study investigates the lasting health effects of leaving school in a bad economy. Three empirical patterns motivate this study: Leaving school in a bad economy has persistent and negative career effects, career and health outcomes are correlated, and fluctuations in contemporaneous economic conditions affect health in the short-run. I draw data from the National Longitudinal Survey of Youth 1979 Age 40 Health Supplement. Members of my sample left school between 1976 and 1992. I find that men who left school when the school-leaving state unemployment rate was high have worse health at age 40 than otherwise similar men, while leaving school in a bad economy lowers depressive symptoms at age 40 among women. A 1 percentage point increase in the school-leaving state unemployment rate leads to a 0.5% to 18% reduction in the measured health outcomes among men and a 6% improvement in depressive symptoms among women.

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

    NASA Astrophysics Data System (ADS)

    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

  5. Returns to Scale in the Production of Hospital Services

    PubMed Central

    Berry, Ralph E.

    1967-01-01

    The primary purpose of this article is to investigate whether or not economies of scale exist in the production of hospital services. In previous studies the results have implied the existence of economies of scale, but the question has not been satisfactorily resolved. The factor most responsible for clouding the issue is the overwhelming prevalence of product differences in the outputs of hospitals. In this study a method which avoids the problem of product differentiation is developed. The analysis strongly supports the conclusion that hospital services are produced subject to economies of scale. PMID:6054380

  16. The Moral Economy of Violence in the US Inner City

    PubMed Central

    Karandinos, George; Hart, Laurie Kain; Castrillo, Fernando Montero; Bourgois, Philippe

    2014-01-01

    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

    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

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

    Eggimann, Sven; Truffer, Bernhard; Maurer, Max

    2016-09-15

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

  13. 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

Sulfur-free fuel is used to eliminate background levels of SO/sub 2/. Addition of an SO/sub 2/ standard gas to the engine during test insures accurate normalization of sampling system flows and quantitative measurement of engine oil economy. Precision of the SO/sub 2/ microcoulometer technique was better than +-8%. The SO/sub 2/ microcoulometer is used during steady state engine operation, and may be used in determining oil consumption from individual cylinders. Existence of engine oil consumption via an aerosol mechanism is investigated and measured. Effects of engine operating temperature and positive crankcase ventilation (PCV) on engine oil economy are given.

  15. The role of food substitutes in a token economy system.

    PubMed

    Scott, D W; Wood, R L

    1987-06-01

    Data from five behaviour management (token economy) units were analysed for periods of 10-20 weeks before and after the use of a food substitute (Complan), provided when insufficient tokens had been earned to buy a full- or part-meal. The efficacy of this form of negative punishment to control disturbed and aggressive behaviour was examined. No evidence was found to suggest that the contingent use of a food substitute made any contribution to the therapeutic process. PMID:3651745

    After systematic attempts to increase a teacher's positive responding to her first-grade students, a token-economy system was implemented as a "last resort". On-task student behavior and relative frequency of positive and negative teacher comments were systematically observed. Data indicated that institution of the token system was associated with a relatively higher percentage of positive than negative comments. Termination and re-implementation of the token system caused reversals of the teacher's behavior.

  17. 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.

  19. Use of a token economy with seriously mentally ill patients: criticisms and misconceptions.

    PubMed

    Corrigan, P W

    1995-12-01

    Although use of a token economy has been shown to have significant impact on adults and children with serious mental illness who participate in inpatient and community treatment programs, the intervention has not been widely adopted. The paper presents common criticisms of token economies, which may explain the infrequent use of this treatment strategy. They include perceptions that token economies are ineffective, that their benefits do not readily generalize to other settings, that token economies do not foster individualized treatment plans, that participating in a token economy is humiliating, that token economies are abusive, that concerns about milieu management are unimportant and irrelevant to treatment delivery in the 1990s, and that effective token economies are impractical. In an effort to rekindle interest in this potent treatment technique, the author shows that many of these criticisms rest on misconceptions and provides rebuttals based on empirical research. He describes three steps in establishing a token economy.

    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.

  1. Optimization of Driving Styles for Fuel Economy Improvement

    SciTech Connect

    Malikopoulos, Andreas; Aguilar, Juan P.

    2012-01-01

    Modern vehicles have sophisticated electronic control units, particularly to control engine operation with respect to a balance between fuel economy, emissions, and power. These control units are designed for specific driving conditions and testing. However, each individual driving style is different and rarely meets those driving conditions. In the research reported here we investigate those driving style factors that have a major impact on fuel economy. An optimization framework is proposed with the aim of optimizing driving styles with respect to these driving factors. A set of polynomial metamodels are constructed to reflect the responses produced by changes of the driving factors. Then we compare the optimized driving styles to the original ones and evaluate the efficiency and effectiveness of the optimization formulation.

  2. 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.

    In national health services, where there is a tendency towards a lack of resources and a continuous increase in demand, it is necessary to implement decisions that promote efficiency. In this paper we focus on potential diversification economies as a strategy to increase efficiency levels. We evaluate the change in efficiency in Catalan hospitals between 1987 and 1992, and analyse the presence of possible diversification economies in each hospital. We use Data Envelopment Analysis, which does not need information on either input or output prices. The results are that the majority of hospitals could increase their efficiency and reduce their costs by diversification to the output-mix offered. Potential productivity gains are between 29% and 46%.

    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.

    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.

  10. 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.

    We have developed a new series of environmentally extended multi-region input-output (MRIO) tables with applications in carbon, water, and ecological footprinting, and Life-Cycle Assessment, as well as trend and key driver analyses. Such applications have recently been at the forefront of global policy debates, such as about assigning responsibility for emissions embodied in internationally traded products. The new time series was constructed using advanced parallelized supercomputing resources, and significantly advances the previous state of art because of four innovations. First, it is available as a continuous 20-year time series of MRIO tables. Second, it distinguishes 187 individual countries comprising more than 15,000 industry sectors, and hence offers unsurpassed detail. Third, it provides information just 1-3 years delayed therefore significantly improving timeliness. Fourth, it presents MRIO elements with accompanying standard deviations in order to allow users to understand the reliability of data. These advances will lead to material improvements in the capability of applications that rely on input-output tables. The timeliness of information means that analyses are more relevant to current policy questions. The continuity of the time series enables the robust identification of key trends and drivers of global environmental change. The high country and sector detail drastically improves the resolution of Life-Cycle Assessments. Finally, the availability of information on uncertainty allows policy-makers to quantitatively judge the level of confidence that can be placed in the results of analyses.

  13. 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.

    Isser, S.N.

    1989-01-01

    The political struggles over oil policy in the 1950s were contests between narrow economic interest groups to collect economic rents, as would be expected if government is considered to be just another forum for rent seeking behavior, with government intervention accepted as a norm. Conversely, the attempt to obtain decontrol of natural gas production during this period, during which consumer interests and pro-market ideology were important factors, presaged the oil politics of the 1970s. The significant impact of consumer interests on oil policy contradicts the expectations of public choice theorists that consumers will be disadvantaged in contests with well organized and wealthy interest groups. The ability of latent interest groups to influence policy when represented by politicians and private actors acting as political entrepreneurs was demonstrated during the 1970s as they dominated oil politics. Substantial economic rents, generated by the OPEC price increases, were transferred to consumers and refiners, while tax break were eliminated despite the economic resources available to producers. The pattern of distribution of those economic rents, as well as various tax breaks and exemptions from controls, was skewed toward small producers and refiners, reflecting a traditional ideological prejudice against big business. Econometric analysis revealed that ideology, party and oil production by constituents were the most important influences on congressional voting.

    The birth and explosive growth of mobile money in Kenya has provided economists with an opportunity to study the evolution and impact of a new financial system. Mobile money is an innovation that allows individuals to store, send, and receive money on their mobile phone via text message. This system has opened up basic financial services to many who were previously excluded, and has had real and measurable impacts on the ability of households to protect themselves against health risks. Using a unique survey instrument covering nearly 2,300 households over 2008-2010, we first document the lightning-fast adoption of mobile money in Kenya, which was faster than most documented modern technologies in the United States. We then present evidence on how this innovation allows households to respond better to unexpected adverse health events. We find that in the face of these events, users of mobile money are better able to tap into remittances to finance additional health care costs without having to forego necessary expenditures on education, food, and other consumption needs.

    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

    The Energy Information Administration (EIA) uses models of the US economy developed by Data Resources, Inc. (DRI) for conducting policy analyses, preparing forecasts for the Annual Energy Outlook, the Short-Term Energy Outlook, and related analyses in conjunction with EIA`s National Energy Modeling System (NEMS) and its other energy market models. Both the DRI Model of the US Economy and the DRI Personal Computer Input-Output Model (PC-IO){sup 2} were developed and are maintained by DRI as proprietary models. This report provides documentation, as required by EIA standards for the use of proprietary models; describes the theoretical basis, structure and functions of both DRI models; and contains brief descriptions of the models and their equations. Appendix A describes how the two large-scale models documented here are used to support the macroeconomic and interindustry modeling associated with the National Energy Modeling System. Appendix B is an article by Stephen McNees of the Federal Reserve Bank of Boston on ``How Large are Economic Forecast Errors.`` This article assesses the forecast accuracy of a number of economic forecasting models (groups) and is attached as an independent assessment of the forecast accuracy of the DRI Model of the US Economy.

    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.

    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.

    2011-06-01

    The development of implementation processes of PHC policies in Latin America, is a challenge yet to be tackled. It is necessary to acknowledge the political economy related to the implementation processes of PHC policies in Latin America from a governance perspective, characterized by the regulatory strategies used and the political processes. The promotion of social values, organizational policies or the introduction of new financial incentives are components of different forms of governance used in health system reforms. The institutional factors of social protection systems in Latin America are considered. Their potential, redistribution limitations and the political economy disputes of the reform strategies are explained by the conflict between the economic and related interests and values of the actors involved. This dynamic of the political process influences regulatory modes inherent in the processes of implementation of PHC policies. The State's governing capacity and levels of health system segmentation impinge on the effectiveness of reform strategies for resolving the conflicts in the policies implemented. PMID:21709974

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.

    2015-04-01

    The origins and trajectory of the crisis in the United States retirement security system have slowly become part of the discussion about the social, political, and economic impacts of population aging. Private sources of retirement security have weakened significantly since 1980 as employers have converted defined benefits precisions to defined contribution plans. The Center for Retirement Research (CRR) now estimates that over half of boomer generation retirees will not receive 70-80% of their wages while working. This erosion of the private retirement security system will likely increase reliance on the public system, mainly Social Security and Medicare. These programs, however, have increasingly become the targets of critics who claim that they are not financially sustainable in their current form and must be significantly modified. This article will focus on an analysis of these trends in the erosion of the United States retirement security system and their connection to changes in the United States political economy as neoliberal, promarket ideology, and policies (low taxes, reduced spending, and deregulation) have become dominant in the private and public sectors. The neoliberal priority on reducing labor costs and achieving maximum shareholder value has created an environment inimical to maintain the traditional system of pension and health care benefits in both the private and public sectors. This article explores the implications of these neoliberal trends in the United States economy for the future of retirement security.

    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

    2004-08-01

    Understanding the impacts of climate change on economic behaviour is an important aspect of deciding when to take policy actions to prevent or mitigate its consequences. This book applies advanced new economics methodologies to assess impacts on potentially vulnerable aspects of the US economy: agriculture, timber, coastal resources, energy expenditure, fishing, outdoor recreation. It is intended to provide improved understanding of key issues raised in the recent Intergovernmental Panel on Climate Change (IPCC) reports. It concludes that some climate change may produce economic gains in the agriculture and forestry sectors, whereas energy, coastal structures, and water sectors may be harmed. The book will serve as an important reference for the scientific, economic, and policy community, and will also be of interest to natural resource/environmental economists as an example of economic valuation techniques. The volume will clearly be of main importance to researchers and policymakers in the US, but will also be influential as a model for assessment of impacts on economies worldwide.

    This paper examines human obesity, measured as weight and body mass index (BMI), and its determinants in Russia. Obesity increased dramatically during transition from a planned to a market economy, by 38%. We determine the factors contributing to rising obesity using individual level data from the Russia Longitudinal Monitoring Survey for 1994 and 2004. We find a strong positive effect of diet/caloric intake and a strong negative effect of smoking on weight and BMI. Gender, education, and income are other major determinants of obesity. Our analysis provides information on dietary patterns and other determinants of obesity in Russia which is essential for formulation and implementation of effective policies designed to reduce the problem and improve the health of the population.

    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.

    The focus of this article is the use of experience made within the literature of the "new" economical discipline of experience economy. By combining a methodological individualism with a causal and dehumanising picture of the process of experience, this discipline conceives economic interactions as acts of autonomy. These acts, it is claimed, are part of economical instrumental reason restructuring itself by using experiences as tools in convincing consumers that they are free to pursue their respective paths of lives. Described through the use of positioning theory, however, this turns out to be a result of an effort of equipping consumers with a new economic norm of forced positioning disguised as deliberate self-positioning.

  3. 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

    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

    The present work endeavors to explore the asymmetric effect of coal price on the China's macro economy by applying nonlinear autoregressive distributed lag (NARDL) model for the period of January 2005 to June 2015. The obtained results indicate that the coal price has a strong asymmetric effect on China's macro economy in the long-run. Namely one percent increase in coal price leads to 0.6194 percent of the China's macro economy increase; and while the coal price is reduces by 1 percent, the China's macro economy will decrease by 0.008 percent. These data indicate that when coal price rises, the effect on China's macro economy is far greater than the price decline. In the short-run, coal price fluctuation has a positive effect on the China's macro 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.

  13. The impact of circular migration on a village economy.

    PubMed

    Hetler, C B

    1989-04-01

    The author examines the economy of a rural village in Indonesia in which a high proportion of households rely on remittances from urban informal sector earnings. Household income and per capita income are analyzed according to whether or not households have at least one temporary migrant, and by the sex and age of the household head. Findings indicate that "remittances from short-term circular migration push many households into the middle and upper income ranges. However, the wealthiest households continue to rely on traditional high earning activities and do not depend on remittances. The poorest households are scattered among those who rely on remittances and those still totally dependent upon traditional low earning village activities, regardless of the sex and age of the household head."

  14. Assessing the efficiency versus the inefficiency of the energy sectors in formerly centrally planned economies

    SciTech Connect

    1995-12-01

    As much the extreme inefficiency of Eastern European energy sectors is emphasized, as little attention their relatively efficient aspects receive. Indeed, a few efficiency indicators show the highest global efficiencies for the formerly centrally planned economies, such as the overall primary to useful energy efficiency. These figures draw the attention to an underestimated feature of former socialist energy sectors and to crucial policy implications: in some respects central planning lead to a more efficient use of energy than the market economy. Consequently, if transitions from the central planning to the market economy are not managed carefully, further reductions in energy efficiency can be expected in some sectors of the economy.

    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.

  16. 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.

    2011-09-01

    Influenced by national nihilism in modern times, many people do not recognize Traditional Chinese Medicine (TCM). Its economic value and social economic support played an important role in the victory of the fight for TCM in the period of the Republic of China. Meanwhile, the education, clinical practice and administration of TCM during the period of Republic of China were all under the constraint of economy. Analysis of the economy's impact on the development of TCM is of practical value. Related to the national economy and the people's livelihood, TCM could be considered both as an important component of national economy and as a state investment. Only when the relationship between TCM and social economy is emphasized and handled well, could the national health industry be rapidly developed. PMID:22340005

    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.

  3. Light-duty vehicle fuel economy improvements, 1979--1998: A consumer purchase model of corporate average fuel economy, fuel price, and income effects

    NASA Astrophysics Data System (ADS)

    Chien, David Michael

    2000-10-01

    The Energy Policy and Conservation Act of 1975, which created fuel economy standards for automobiles and light trucks, was passed by Congress in response to the rapid rise in world oil prices as a result of the 1973 oil crisis. The standards were first implemented in 1978 for automobiles and 1979 for light trucks, and began with initial standards of 18 MPG for automobiles and 17.2 MPG for light trucks. The current fuel economy standards for 1998 have been held constant at 27.5 MPG for automobiles and 20.5 MPG for light trucks since 1990--1991. While actual new automobile fuel economy has almost doubled from 14 MPG in 1974 to 27.2 MPG in 1994, it is reasonable to ask if the CAFE standards are still needed. Each year Congress attempts to pass another increase in the Corporate Average Fuel Economy (CAFE) standard and fails. Many have called for the abolition of CAFE standards citing the ineffectiveness of the standards in the past. In order to determine whether CAFE standards should be increased, held constant, or repealed, an evaluation of the effectiveness of the CAFE standards to date must be established. Because fuel prices were rising concurrently with the CAFE standards, many authors have attributed the rapid rise in new car fuel economy solely to fuel prices. The purpose of this dissertation is to re-examine the determinants of new car fuel economy via three effects: CAFE regulations, fuel price, and income effects. By measuring the marginal effects of the three fuel economy determinants upon consumers and manufacturers choices, for fuel economy, an estimate was made of the influence of each upon new fuel economy. The conclusions of this dissertation present some clear signals to policymakers: CAFE standards have been very effective in increasing fuel economy from 1979 to 1998. Furthermore, they have been the main cause of fuel economy improvement, with income being a much smaller component. Furthermore, this dissertation has suggested that fuel prices have

    Dickerson, Faith B; Tenhula, Wendy N; Green-Paden, Lisa D

    2005-06-15

    The token economy is a treatment intervention based on principles of operant conditioning and social learning. Developed in the 1950s and 1960s for long-stay hospital patients, the token economy has fallen out of favor since that time. The current review was undertaken as part of the 2003 update of the schizophrenia treatment recommendations of the Patient Outcomes Research Team (PORT). A total of 13 controlled studies of the token economy were reviewed. As a group, the studies provide evidence of the token economy's effectiveness in increasing the adaptive behaviors of patients with schizophrenia. Most of the studies are limited, however, by methodological shortcomings and by the historical context in which they were performed. More research is needed to determine the specific benefits of the token economy when administered in combination with contemporary psychosocial and psychopharmacological treatments.

  16. Does a robotic scrub nurse improve economy of movements?

    NASA Astrophysics Data System (ADS)

    Wachs, Juan P.; Jacob, Mithun; Li, Yu-Ting; Akingba, George

    2012-02-01

    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

    2015-09-01

    This study postulates that traditional human error identification techniques fail to consider motion economy principles and, accordingly, their applicability in operating theatres may be limited. This study addresses this gap in the literature with a dual aim. First, it identifies the principles of motion economy that suit the operative environment and second, it develops a new error mode taxonomy for human error identification techniques which recognises motion economy deficiencies affecting the performance of surgeons and predisposing them to errors. A total of 30 principles of motion economy were developed and categorised into five areas. A hierarchical task analysis was used to break down main tasks of a urological laparoscopic surgery (hand-assisted laparoscopic nephrectomy) to their elements and the new taxonomy was used to identify errors and their root causes resulting from violation of motion economy principles. The approach was prospectively tested in 12 observed laparoscopic surgeries performed by 5 experienced surgeons. A total of 86 errors were identified and linked to the motion economy deficiencies. Results indicate the developed methodology is promising. Our methodology allows error prevention in surgery and the developed set of motion economy principles could be useful for training surgeons on motion economy principles.

    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.

  3. The production of information in the attention economy.

    PubMed

    Ciampaglia, Giovanni Luca; Flammini, Alessandro; Menczer, Filippo

    2015-05-19

    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.

    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.

    In the current investigation, we evaluated the effects of open and closed economies on the adaptive behavior of 2 individuals with developmental disabilities. Across both types of economy, progressive-ratio (PR) schedules were used in which the number of responses required to obtain reinforcement increased as the session progressed. In closed-economy sessions, participants were able to obtain reinforcement only through interaction with the PR schedule requirements (i.e., more work resulted in more reinforcer access). In open-economy sessions, participants obtained reinforcers by responding on the PR schedule and were given supplemental (free) access to the reinforcers after completion of the session. In general, more responding was associated with the closed economy. PMID:16270843

    2011-01-01

    Fijian bodies have become a valuable commodity in the economy of war. Remittances from workers overseas are Fiji's largest income – exceeding that of tourism and sugar export. This essay examines historical and contemporary representations of the black male body that perpetuate the exploitation of Fijians by inscribing the Fijian male body as warrior, criminal and protector. Taking a multidisciplinary approach informed by sociology, cultural theory, Pacific studies, visual culture, feminist and post-colonial theory, my practice is the vehicle through which I address issues of neocolonial commodification of Fijian bodies. Through an analysis of my own staged photographs and vernacular images taken by Fijians working for private security military companies and British and US armies, I hope to challenge audiences to consider their own perceptions of Fijian agency and subjectivity. By theorising the politicisation of the black body and interrogating colonial representations of blackness, I argue that we can begin to create links between the historical and contemporary exploitation of Fijians and that at the essence of both is an underlying racial hierarchy and economic requirement for cheap and, arguably, expendable labour.

Through an analysis of my own staged photographs and vernacular images taken by Fijians working for private security military companies and British and US armies, I hope to challenge audiences to consider their own perceptions of Fijian agency and subjectivity. By theorising the politicisation of the black body and interrogating colonial representations of blackness, I argue that we can begin to create links between the historical and contemporary exploitation of Fijians and that at the essence of both is an underlying racial hierarchy and economic requirement for cheap and, arguably, expendable labour.

  12. [From biodiversity to biodiversification: a new economy of nature?].

    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?

    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.

    2011-11-01

    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.

    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.

    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.

  8. The deregulated global economy: women workers and strategies of resistance.

    PubMed

    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.

    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.

    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.

    In the last decade, the token economy has been extended widely across populations and behaviors in treatment, rehabilitation, educational, and community settings. Outcome research has expanded as well to include large-scale program evaluations and comparative and combined treatment studies of the token economy. In a previous review (Kazdin & Bootzin, 1972), several obstacles were identified for the effective application of the token economy. These included identifying procedures to enhance program efficacy, to train staff, to overcome client resistance, and to promote long-term maintenance and transfer of training. The present paper discusses recent advances in research and reviews progress on the major issues identified previously. New issues have become salient in the last decade that pertain to the extension of the token economy to institutional settings. The demands for maintaining the integrity of treatment, the ability to integrate token economies within existing institutional constraints, and the disseminability of the procedures on a large scale are major issues that may dictate the future of the token economy.

    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

  16. Lower-body determinants of running economy in male and female distance runners.

    PubMed

    2014-05-01

    A variety of training approaches have been shown to improve running economy in well-trained athletes. However, there is a paucity of data exploring lower-body determinants that may affect running economy and account for differences that may exist between genders. Sixty-three male and female distance runners were assessed in the laboratory for a range of metabolic, biomechanical, and neuromuscular measures potentially related to running economy (ml·kg(-1)·min(-1)) at a range of running speeds. At all common test velocities, women were more economical than men (effect size [ES] = 0.40); however, when compared in terms of relative intensity, men had better running economy (ES = 2.41). Leg stiffness (r = -0.80) and moment arm length (r = 0.90) were large-extremely largely correlated with running economy and each other (r = -0.82). Correlations between running economy and kinetic measures (peak force, peak power, and time to peak force) for both genders were unclear. The relationship in stride rate (r = -0.27 to -0.31) was in the opposite direction to that of stride length (r = 0.32-0.49), and the relationship in contact time (r = -0.21 to -0.54) was opposite of that of flight time (r = 0.06-0.74). Although both leg stiffness and moment arm length are highly related to running economy, it seems that no single lower-body measure can completely explain differences in running economy between individuals or genders. Running economy is therefore likely determined from the sum of influences from multiple lower-body attributes.

    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.

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.

  3. The real new economy.

    Farrell, Diana

    2003-10-01

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

  4. Techno economic systems and excessive consumption: a political economy of 'pathological' gambling.

    PubMed

    Reith, Gerda

    2013-12-01

    This article argues that gambling is a paradigmatic form of consumption that captures the intensified logic at the heart of late modern capitalist societies. As well as a site of intensified consumption, it claims that gambling has also become the location of what has been described as a new form of 'social pathology' related to excess play. Drawing on Castells' (1996) notion of techno-economic systems, it explores the ways that intersections between technology, capital and states have generated the conditions for this situation, and critiques the unequal distribution of gambling environments that result. It argues that, while the products of these systems are consumed on a global scale, the risks associated with them tend to be articulated in bio-psychological discourses of 'pathology' which are typical of certain types of knowledge that have salience in neo-liberal societies, and which work to conceal wider structural relationships. We argue that a deeper understanding of the political and cultural economy of gambling environments is necessary, and provide a synoptic overview of the conditions upon which gambling expansion is based. This perspective highlights parallels with the wider global economy of finance capital, as well as the significance of intensified consumption, of which gambling is an exemplary instance. It also reveals the existence of a geo-political dispersal of 'harms', conceived as deteriorations of financial, temporal and social relationships, which disproportionately affect vulnerable social groups. From this, we urge an understanding of commercial gambling based on a critique of the wider social body of gambling environments within techno economic systems, rather than the (flawed) individual bodies within them.

    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 economy of C use by root nodules was examined in two symbioses, Vigna unguiculata (L.) Walp. (cv. Caloona):Rhizobium CB756 and Lupinus albus L. (cv. Ultra):Rhizobium WU425 over a 2-week period in early vegetative growth. Plants were grown in minus N water culture with cuvettes attached to the nodulated zone of their primary roots for collection of evolved CO2 and H2. Increments in total plant N and in C and N of nodules, and C:N weight ratios of xylem and phloem exudates were studied by periodic sampling from the plant populations. Itemized budgets were constructed for the partitioning and utilization of C in the two species. For each milligram N fixed and assimilated by the cowpea association, 1.54 ± 0.26 (standard error) milligrams C as CO2 and negligible H2 were evolved and 3.11 milligrams of translocated C utilized by the nodules. Comparable values for nodules of the lupin association were 3.64 ± 0.28 milligrams C as CO2, 0.22 ± 0.05 milligrams H2, and 6.58 milligrams C. More efficient use of C by cowpea nodules was due to a lesser requirement of C for synthesis of exported N compounds, a smaller allocation of C to nodule dry matter, and a lower evolution of CO2. The activity of phosphoenolpyruvate carboxylase in nodule extracts and the rate of 14CO2 fixation by detached nodules were greater for the cowpea symbiosis (0.56 ± 0.06 and 0.22 milligrams C as CO2 fixed per gram fresh weight per hour, respectively) than for the lupin 0.06 ± 0.02 and 0.01 milligrams C as CO2 fixed per gram fresh weight per hour. The significance of the data was discussed in relation to current information on theoretical costs of nitrogenase functioning and associated nodule processes. PMID:16661076

  9. Energy economy of salmon aquaculture in the Baltic sea

    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

    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.

    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.

This device is a gasket which is installed between the intake manifold and the cylinder head. The device is claimed to improve fuel economy and driveability. The results of EPA testing show the Dresser Economizer device does not have any significant effect on regulated exhaust emissions or fuel economy.

  13. Reaping Environmental Benefits of a Global Hydrogen Economy: How Large, Fow Soon, and at What Risks?

    The Western world has taken an aggressive posture to transition to a global hydrogen economy. While numerous technical challenges need to be addressed to achieve this it is timely to examine the environmental benefits and risks of this transition. 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. 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 leak rates in global hydrogen infrastructure and the future evolution of microbial soil sink of hydrogen that determines its current lifetime (about 2 years) are principal sources of uncertainty in our assessment.

  15. 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.

    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.

    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.

  2. 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

  4. Predicting Individual Fuel Economy

    SciTech Connect

    Lin, Zhenhong; Greene, David L

    2011-01-01

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

    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.

  6. Impact of non-petroleum vehicle fuel economy on GHG mitigation potential

    The fuel economy of gasoline vehicles will increase to meet 2025 corporate average fuel economy standards (CAFE). However, dedicated compressed natural gas (CNG) and battery electric vehicles (BEV) already exceed future CAFE fuel economy targets because only 15% of non-petroleum energy use is accounted for when determining compliance. This study aims to inform stakeholders about the potential impact of CAFE on life cycle greenhouse gas (GHG) emissions, should non-petroleum fuel vehicles displace increasingly fuel efficient petroleum vehicles. The well-to-wheel GHG emissions of a set of hypothetical model year 2025 light-duty vehicles are estimated. A reference gasoline vehicle is designed to meet the 2025 fuel economy target within CAFE, and is compared to a set of dedicated CNG vehicles and BEVs with different fuel economy ratings, but all vehicles meet or exceed the fuel economy target due to the policy’s dedicated non-petroleum fuel vehicle incentives. Ownership costs and BEV driving ranges are estimated to provide context, as these can influence automaker and consumer decisions. The results show that CNG vehicles that have lower ownership costs than gasoline vehicles and BEVs with long distance driving ranges can exceed the 2025 CAFE fuel economy target. However, this could lead to lower efficiency CNG vehicles and heavier BEVs that have higher well-to-wheel GHG emissions than gasoline vehicles on a per km basis, even if the non-petroleum energy source is less carbon intensive on an energy equivalent basis. These changes could influence the effectiveness of low carbon fuel standards and are not precluded by the light-duty vehicle GHG emissions standards, which regulate tailpipe but not fuel production emissions.

  7. Ruptures, rights, and repair: the political economy of trauma in Haiti.

    PubMed

    James, Erica Caple

    2010-01-01

    This article analyzes the unintended consequences of humanitarian and development interventions in Haiti implemented to facilitate its postconflict transition following the period of military rule between 1991 and 1994. International and national governmental and nongovernmental initiatives to provide redress and healing to victims of human rights abuses from this period inadvertently contributed to the growth of a political economy of trauma. I argue that state-sponsored and non-state interventions aimed at truth seeking, acknowledging past ruptures, and reparations have intersected with the politics of local communities in ways that contribute to the commoditization of suffering in the political economy of trauma. The experience of a woman whose bodily integrity and personal sovereignty were violated by members of Haiti's terror apparatus demonstrates the presence of a terror economy. My witnessing of her interactions with the international and national humanitarian and development aid organizations that assisted her in the aftermath of violation revealed the contours of the compassion economy. It is the compassion economy that is the particular focus of this article. I evaluate whether rendering visible or audible the individual and collective suffering of the past truly aid processes of social reconstruction, democratization, and peace building, especially in states plagued with ongoing social, political, and economic insecurity. I argue that the forms of citizenship that these interventions engender are rarely permanent, especially in fragile or failed states, and may exacerbate the societal cleavages that gave rise to conflict.

  9. Ecological accounting and evaluation of urban economy: Taking Beijing city as the case

    NASA Astrophysics Data System (ADS)

    Ji, Xi

    2011-03-01

    Urban economy is confronted with increasing biophysical limitations derived from the exhaustion of natural resources and the depletion of environmental capacity, and human cultural diversity has been declining during the fast urbanization. The conventional anthropocentric economics, regarding the natural environment as the 'exterior' of human economy, is invalid in the scientific evaluation on the contribution of natural resources and environment as well as human culture when facing the current urban crises. The theory of embodied cosmic exergy, as the latest development of ecological economics and ecological thermodynamics, is introduced in this study to construct an ecological evaluation framework of urban economy. The advantage of embodied cosmic exergy dedicated to ecological economics has been discussed in comparison with other ecological evaluation alternatives. Transformities describing hierarchies and manifesting quality are systematically calculated and tabulated. A new framework of embodied cosmic exergy based on network accounting (EmexNA) is sketched out in this study, taking not only diversity flows but also ecological stocks into consideration. The stock based concept of 'ecological wealth' and the flow based concept of 'ecological cost' as well as related evaluation indicators are developed based on EmexNA. Taking Beijing city as the case, the network accounting and related ecological evaluation of a practical urban economy are carried out in this study in the light of the basic social, economic and environmental data available from 1990 to 2005 of Beijing. The system construction and the ecological mechanism of the development of Beijing economy are correspondingly illuminated and discussed.

  14. Landscape and zonal features of the formation of producing economy in Russia

    2016-04-01

    Based on analysis of the extensive source base, including complex landscape, component, paleogeographic and archeological published and scientific materials as well as the connected analysis of published paleogeographical, paleolandscape and historical and geographic maps of the territory of Russia landscape and zonal features of the transition from appropriating economy to producing economy were determined. All the specifics of historical changes in the landscape use of the vast areas of Russia is caused by the variety of its landscape zones and the specifics of their constituent landscapes. Human economic activities as a factor of differentiation and development of landscapes became apparent almost in all landscape zones together with the emergence of the producing type of economy from the Aeneolithic-Bronze Age (Atlantic period) in the southern steppe regions (in the northern areas of the main centers of the producing economy) and from the Bronze Age in the forest areas. The emergence of the producing economy in the forest-steppe and steppe landscape zones on the territory of Russia is dated IV (Aeneolithic) - III (Early Bronze Age) millennium BC. It is from this period that on the European part of Russia and in Siberia the so-called Neolithic revolution begins. The use of copper and bronze axes helped to develop new areas for planting crops in the forest-steppe zone. In the forest-steppe zone swidden and lea tillage cultivation develops. In the steppe and forest-steppe Eurasia depending on the local landscape conditions two ways of producing economy with a predominance of cattle-breeding developed: nomadic cattle breeding and house cattle breeding with a significant influence of agriculture in the economy and long-term settlements. The steppe areas were completely dominated by the mobile nomadic herding, breeding cattle and small cattle. Along with the valley landscapes the interfluvial landscapes were also actively explored. Almost in all the steppe areas

  15. 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.

  18. Toward a political and moral economy of aging: an alternative perspective.

    PubMed

    Hendricks, J; Leedham, C A

    1992-01-01

    A conceptual framework for empowerment of the elderly is proposed, using variations on Gramsci's hegemony and Thompson's moral economy to complement recent political economic and social psychological theories. The political economy and social psychology of aging highlight structural constraints and actors' reactions without articulating a model for empowerment. Gramsci's idea of hegemony as new moral and philosophical leadership calls for principles of social and economic organization deserving assent because they maximize people's chances for a decent life at all ages. Hegemony, as normalizing dominance, reveals ways in which the elderly may be disempowered as well as possibilities for intervention. Underlying diverse forms of hegemony are economic arrangements and an array of cultural norms. In contrast to Thompson, the authors argue that norms implicit in moral economy vary with changes in social context. In the process, two ideal types of moral economy are elaborated, grounded in exchange value and use value, respectively. Empowerment may be found through a moral economy grounded in use value appropriate to advanced industrial society that is consonant with Gramsci's new hegemony. Implications for health and income maintenance policies are explored.

    Published information on aspects related to muscle damage and running economy is both limited and contradictory. To contribute to the current debate, we investigated the effects of an eccentric exercise session on selected muscle damage indices in relation to running economy using 10 (mean age 23 +/- 1 years) healthy male volunteers. The eccentric exercise session consisted of 120 (12 x 10) maximal voluntary repetitions by each randomly selected leg at the angular velocity of 1.05 rad . s (-1). Muscle damage (creatine kinase, delayed onset muscle soreness, range of movement, and eccentric, concentric and isometric [at 60 degrees and 110 degrees knee flexion] peak torque) and running economy (oxygen consumption, pulmonary ventilation, respiratory exchange ratio and breaths per minute during treadmill running at 133 and 200 m . min (-1)) indicators, were assessed pre-, 24-, 48-, 72- as well as 96-h after exercise. All muscle damage indicators revealed significant changes at almost all time-points of assessment compared to pre-exercise data (p < 0.05). However, none of the running economy parameters disclosed any significant change throughout the study (p > 0.05). It was concluded that changes in muscle damage and muscle performance as measured in this study are not reflected by concomitant alterations in running economy at submaximal intensities.

  20. Scaling of Thermoacoustic Refrigerators

    NASA Astrophysics Data System (ADS)

    Li, Y.; Zeegers, J. C. H.; ter Brake, H. J. M.

    2008-03-01

    The possibility of scaling-down thermoacoustic refrigerators is theoretically investigated. Standing-wave systems are considered as well as traveling-wave. In the former case, a reference system is taken that consists of a resonator tube (50 cm) with a closed end and a PVC stack (length 5 cm). Helium is used at a mean pressure of 10 bar and an amplitude of 1 bar. The resulting operating frequency is 1 kHz. The variation of the performance of the refrigerator when scaled down in size is computed under the prerequisites that the temperature drop over the stack or the energy flux or its density are fixed. The analytical results show that there is a limitation in scaling-down a standing-wave thermoacoustic refrigerator due to heat conduction. Similar scaling trends are considered in traveling-wave refrigerators. The traveling-wave reference system consists of a feedback inertance tube of 0.567 m long, inside diameter 78 mm, a compliance volume of 2830 cm3 and a 24 cm thermal buffer tube. The regenerator is sandwiched between two heat exchangers. The system is operated at 125 Hz and filled with 30 bar helium gas. Again, the thermal conductance forms a practical limitation in down-scaling.

  2. 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.

    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.

    ABSTRACT Objectives: Socio‐demographic indicators closely relate to sleep in industrialized populations. However we know very little about how such factors impact sleep in populations undergoing industrialization. Within populations transitioning to the global economy, the preliminary evidence has found an inconsistent relationship between socio‐demographics and sleep complaints across countries and social strata. Materials and methods: Surveys were conducted on a sample of rural Sakha (Yakut) adults (n = 168) during the autumn of 2103 to assess variation in socio‐demographics and sleep complaints, including trouble sleeping and daytime sleepiness. Socio‐demographic variables included age, gender, socioeconomic measures, and markers of traditional/market‐based lifestyle. We tested whether the socio‐demographic variables predicted sleep complaints using bivariate analyses and multiple logistic regressions. Results: Trouble sleeping was reported by 18.5% of the participants and excessive daytime sleepiness (EDS) by 17.3%. Trouble sleeping was significantly predicted by older age, female gender, and mixing traditional and market‐based lifestyles. EDS was not significantly predicted by any socio‐demographic variable. Discussion: These findings support the few large‐scale studies that found inconsistent relationships between measures of socioeconomic status and sleep complaints in transitioning populations. Employing a mix of traditional and market‐based lifestyles may leave Sakha in a space of vulnerability, leading to trouble sleeping. Am J Phys Anthropol 157:641–647, 2015. © 2015 The Authors.

    The purpose of this study was to determine if minimalist shoes improve time trial performance of trained distance runners and if changes in running economy, shoe mass, stride length, stride rate and footfall pattern were related to any difference in performance. Twenty-six trained runners performed three 6-min sub-maximal treadmill runs at 11, 13 and 15 km·h(-1) in minimalist and conventional shoes while running economy, stride length, stride rate and footfall pattern were assessed. They then performed a 5-km time trial. In the minimalist shoe, runners completed the trial in less time (effect size 0.20 ± 0.12), were more economical during sub-maximal running (effect size 0.33 ± 0.14) and decreased stride length (effect size 0.22 ± 0.10) and increased stride rate (effect size 0.22 ± 0.11). All but one runner ran with a rearfoot footfall in the minimalist shoe. Improvements in time trial performance were associated with improvements in running economy at 15 km·h(-1) (r = 0.58), with 79% of the improved economy accounted for by reduced shoe mass (P < 0.05). The results suggest that running in minimalist shoes improves running economy and 5-km running performance.

    The psychiatric reform process requires the implementation of public policies that guarantee the work inclusion of individuals with mental disorders. To do this, work must be understood as a promoter of autonomy, emancipation and citizenship. The objective of this study is to reflect on the theoretical concepts related to social insertion through work, with the purpose of exploring the inclusion of individuals with mental disorders in the work market. The concepts social company and solidary economy where selected as fundamental for the study. In the social company, the subject is considered to be a social being, focusing on the development process towards emancipation. In solidary economy, the objective is to develop an economy that is more just, equal and solidary. Further discussions on these concepts should be developed to support the implementation of projects for social inclusion through work.

    A two-part systematic review was undertaken to assess the effectiveness of token economies in increasing rates of appropriate classroom behavior for students demonstrating behavioral difficulties. The first part of the review utilized the recently published What Works Clearinghouse (WWC) standards for evaluating single-subject research to determine the extent to which eligible studies demonstrated sufficient evidence to classify the token economy as an evidence-based practice. The second part of the review employed meta-analytic techniques across four different types of effect sizes to evaluate the quantitative strength of the findings. Methodological strengths and weaknesses across the studies were systematically investigated. Results indicated that the extant research on token economies does not provide sufficient evidence to be deemed best-practice based on the WWC criteria. PMID:21930008

  12. 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.

    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.

  15. Scales of rock permeability

    Permeability is a transport property which is currently measured in Darcy units. Although this unit is very convenient for most purposes, its use prevents from recognizing that permeability has units of length squared. Physically, the square root of permeability can thus be seen as a characteristic length or a characteristic pore size. At the laboratory scale, the identification of this characteristic length is a good example of how experimental measurements and theoretical modelling can be integrated. Three distinct identifications are of current use, relying on three different techniques: image analysis of thin sections, mercury porosimetry and nitrogen adsorption. In each case, one or several theoretical models allow us to derive permeability from the experimental data (equivalent channel models, statistical models, effective media models, percolation and network models). Permeability varies with pressure and temperature and this is a decisive point for any extrapolation to crustal conditions. As far as pressure is concerned, most of the effect is due to cracks and a model which does not incorporate this fact will miss its goal. Temperature induced modifications can be the result of several processes: thermal cracking (due to thermal expansion mismatch and anisotropy, or to fluid pressure build up), and pressure solution are the two main ones. Experimental data on pressure and temperature effects are difficult to obtain but they are urgently needed. Finally, an important issue is: up to which point are these small scale data and models relevant when considering formations at the oil reservoir scale, or at the crust scale? At larger scales the identification of the characteristic scale is also a major goal which is examined.

    The consumer behavior of institutionalized retarded clients in a sheltered workshop token economy were evaluated by changing prices in the workshop store. In the first experiment we found that clients displayed elasticity of demand in that raising the prices of frequently purchased goods reduced the frequency and amount spent on more expendable items. Results from the second experiment showed that this change in spending pattern was not due to the relative modal unit price of item classes. The regulation of demand for consumer goods is a potentially useful way to maintain economic balance and effectiveness of a token economy. PMID:970416

    In the global transition towards a more efficient and low-carbon economy, renewable energy plays a major role in displacing fossil fuels, meeting global energy demand while reducing carbon dioxide emissions. In Europe, Variable Renewable Sources (VRS), such as wind and solar power sources, are becoming a relevant share of the generation portfolios in many countries. Beside the indisputable social and environmental advantages of VRS, on the short medium term the VRS-induced lowering energy prices and increasing price's volatility might challenge traditional power sources and, among them, hydropower production, because of smaller incomes and higher maintenance costs associated to a more flexible operation of power systems. In this study, we focus on the Swiss hydropower sector analysing how different low-carbon targets and strategies established at the Swiss and European level might affect energy price formation and thus impact - through hydropower operation - water availability and ecosystems services at the catchment scale. We combine a hydrological model to simulate future water availability and an electricity market model to simulate future evolution of energy prices based on official Swiss and European energy roadmaps and CO2 price trends in the European Union. We use Multi-Objective optimization techniques to design alternative hydropower reservoir operation strategies, aiming to maximise the hydropower companies' income or to provide reliable energy supply with respect to the energy demand. This integrated model allows analysing to which extent global low-carbon policies impact reservoir operation at the local scale, and to gain insight on how to prioritise compensation measures and/or adaptation strategies to mitigate the impact of VRS on hydropower companies in increasingly water constrained settings. Numerical results are shown for a real-world case study in the Swiss Alps.

    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.

    The involvement of Caribbean youth in drug distribution (marijuana from the mid-1960s to 1981; cocaine hydrochloride powder and crack from 1981 to 1987, the time of writing) throughout the Circum-Caribbean area and in North America is described. Social, economic, and cultural outcomes of these engagements are highlighted, and the relationship between the underground economy of drugs and the corporate, capitalist economy is explored. Responding to high rates of unemployment and to other problems of migrant adaptation, young Caribbean African males established a multimillion dollar marijuana (ganja) trading network which linked cultivators on the islands with exporters/importers and street-level distributors in North American cities. By 1976, its participants had become Rastafarians, or followers of an ideology of self-reliance and indigenous development. Following its precepts, they reinvested marijuana revenues to revive cottage industry and agriculture. In Caribbean or minority neighborhoods, therefore, marijuana was a "positive vibration" and its distributors were lionized.

    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.

  18. 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

    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.

    2012-12-01

    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.

    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.

  18. 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

    1982-01-01

    Most introductory physics courses emphasize highly idealized problems with unique well-defined answers. Though many textbooks complement these problems with estimation problems, few books present anything more than an elementary discussion of scaling. This paper presents some fundamentals of scaling in the zoological domain—a domain complex by any standard, but one also well suited to illustrate the power of very simple physical ideas. We consider the following animal characteristics: skeletal weight, speed of running, height and range of jumping, food consumption, heart rate, lifetime, locomotive efficiency, frequency of wing flapping, and maximum sizes of animals that fly and hover. These relationships are compared to zoological data and everyday experience, and match reasonably well.

    2012-05-01

    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.

    2011-01-01

    Background and Aims Models simulating nitrogen use by plants are potentially efficient tools to optimize the use of fertilizers in agriculture. Most crop models assume that a target nitrogen concentration can be defined for plant tissues and formalize a demand for nitrogen, depending on the difference between the target and actual nitrogen concentrations. However, the teleonomic nature of the approach has been criticized. This paper proposes a mechanistic model of nitrogen economy, NEMA (Nitrogen Economy Model within plant Architecture), which links nitrogen fluxes to nitrogen concentration and physiological processes. Methods A functional–structural approach is used: plant aerial parts are described in a botanically realistic way and physiological processes are expressed at the scale of each aerial organ or root compartment as a function of local conditions (light and resources). Key Results NEMA was developed for winter wheat (Triticum aestivum) after flowering. The model simulates the nitrogen (N) content of each photosynthetic organ as regulated by Rubisco turnover, which depends on intercepted light and a mobile N pool shared by all organs. This pool is enriched by N acquisition from the soil and N release from vegetative organs, and is depleted by grain uptake and protein synthesis in vegetative organs; NEMA accounts for the negative feedback from circulating N on N acquisition from the soil, which is supposed to follow the activities of nitrate transport systems. Organ N content and intercepted light determine dry matter production via photosynthesis, which is distributed between organs according to a demand-driven approach. Conclusions NEMA integrates the main feedbacks known to regulate plant N economy. Other novel features are the simulation of N for all photosynthetic tissues and the use of an explicit description of the plant that allows how the local environment of tissues regulates their N content to be taken into account. We believe this represents

  16. 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.

Differing from other economic impact studies in its emphasis on human capital as an economic resource, rather than on institutional spending and investment, the study involved the examination of existing statewide…

    Trehearn, Tamra L; Buresh, Robert J

    2009-01-01

    Flexibility has been controversially suggested as one of the biomechanical factors contributing to the variability observed in running economy among distance runners. The purpose of this investigation was to determine the magnitude of the relationship between sit-and-reach flexibility and running economy in men and women. Eight collegiate distance runners (4 men and 4 women) served as subjects for this correlational study (age = 19.9 +/- 1.25 years; VO2max = 63.2 +/- 3.4 mlxkgxmin). Each subject's flexibility was measured using the standard sit-and-reach test, and running economy was recorded during an incremental maximal treadmill test at both absolute (men = 241.2 mxmin; women = 198.32 mxmin) and relative (10-km pace) velocities. Statistical analyses indicated a significant relationship between sit-and-reach scores and running economy at an absolute velocity (r = 0.826, p of the energy-efficient function of the elastic components in the muscles and tendons during the stretch-shortening cycle.

  11. Emergent dynamics of the climate-economy system in the Anthropocene.

    PubMed

    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.
