    1980-05-01

    How much of the world's oil and energy supply will the non-OPEC less-developed countries (NOLDCs) demand in the next decade. Will their requirements be small and thus fairly insignificant compared with world demand, or large and relatively important. How will world demand be affected by the economic growth of the NOLDCs. In this report, we try to develop some reasonable forecasts of NOLDC energy demands in the next 10 years. Our focus is mainly on the demand for oil, but we also give some attention to the total commercial energy requirements of these countries. We have tried to be explicit about the uncertainties associated with our forecasts, and with the income and price elasticities on which they are based. Finally, we consider the forecasts in terms of their implications for US policies concerning the NOLDCs and suggest areas of future research on NOLDC energy issues.

    The alarming increase in the scarcity of water in various parts of the world. Scarcity of water in the Arab countries is not a new phenomenon—although population growth and economic development exacerbate the scarcity. Therefore, it is useful to examine how the problem has been dealt with during millennia of experience in the Arab world. Water is a main issue in many countries especially in those Arab countries; it has focused a global attention on the need for a stronger and more appropriate...

  4. Energy demand, energy substitution and economic growth : Evidence from developed and developing countries

    Abd Aziz, Azlina

    This thesis contributes to the literature on energy demand in three ways. Firstly, it examines the major determinants of energy demand using a panel of 23 developed countries and 16 developing countries during 1978 to 2003. Secondly, it examines the demand for energy in the industrial sector and the extent of inter-fuel substitution, as well as substitution between energy and non-energy inputs, using data from 5 advanced countries and 5 energy producer's developing countries. Third, the thesis investigates empirically the relationship between energy consumption and economic growth for these groups of countries over a 26-year period. The empirical results of this study confirm the majority of the findings in energy demand analysis. Income and price have shown to be important determinants for energy consumption in both developed and developing countries. Moreover, both economic structure and technical progress appear to exert significant impacts on energy consumption. Income has a positive impact on energy demand and the effect is larger in developing countries. In both developed and developing countries, price has a negative impact but these effects are larger in developed countries than in developing countries. The share of industry in GDP is positive and has a greater impact on energy demand in developing countries, whereas technological progress is found to be energy using in developed countries and energy saving in developing countries. With respect to the analysis of inter-factor and inter-fuel substitution in industrial energy demand, the results provide evidence for substitution possibilities between factor inputs and fuels. Substitutability is observed between capital and energy, capital and labour and labour and energy. These findings confirm previous evidence that production technologies in these countries allow flexibility in the capital-energy, capital-labour and labour-energy mix. In the energy sub-model, the elasticities of substitution show that large

  5. Oil demand and price elasticity of energy consumption in the GCC countries: A panel cointegration analysis

    Full Text Available This paper examines the cointegrating relationship between oil demand and price elasticity of energy consumption in the Gulf Co-operation Council (GCC countries during the period 1980-2010. The paper has applied the recently developed panel cointegration techniques, Dynamic Ordinary Least Squares (DOLS and panel DOLS in a panel of GCC countries. The region is being recognized as the major region of oil production and export in the global economy. In recent times, the region is emerging as a fastest growing oil consuming region globally. This fast increase in the level of oil consumption in the major oil exporting countries raises the energy security implications in the sphere of the growing oil demand in the world economy. This is likely to bring many pitfalls in the form of price distortions and reduced growth rates in and outside the oil export region. The empirical finding reveals a cointegrating relationship among the variables and indicates an income elastic and price inelastic demand for oil in the long-run in the GCC countries. The outcomes of income elastic and price inelastic demand for oil are also consistent in the short-run. The income and price inelastic demand for oil though exists for a full panel of countries but vary across the GCC countries. The result of the Granger Causality test also depicts a unidirectional causality running from income to oil consumption and bidirectional causality running between oil prices and income in the GCC countries. Moreover, the outcomes reveal that demand for oil varies positively with the growth of income and negatively with the price level in the economy.

  6. Is the demand for alcoholic beverages in developing countries sensitive to price? Evidence from China.

    Economic literature in developed countries suggests that demand for alcoholic beverages is sensitive to price, with an estimated price elasticity ranging from -0.38 for beer and -0.7 for liquor. However, few studies have been conducted in developing countries. We employ a large individual-level dataset in China to estimate the effects of price on alcohol demand. Using the data from China Health and Nutrition Survey for the years 1993, 1997, 2000, 2004 and 2006, we estimate two-part models of alcohol demand. Results show the price elasticity is virtually zero for beer and only -0.12 for liquor, which is far smaller than those derived from developed countries. Separate regressions by gender reveals the results are mainly driven by men. The central implication of this study is, while alcohol tax increases can raise government revenue, it alone is not an effective policy to reduce alcohol related problems in China.

    2017-03-01

    Full Text Available The creation of a Europe-wide electricity market combined with the increased intermittency of supply from renewable sources calls for an investigation into the risk of aggregate peak demand. This paper makes use of a risk model to assess differences in time-use data from residential end-users in five different European electricity markets. Drawing on the Multinational Time-Use Survey database, it assesses risk in relation to the probability of electrical appliance use within households for five European countries. Findings highlight in which countries and for which activities the risk of aggregate peak demand is higher and link smart home solutions (automated load control, dynamic pricing and smart appliances to different levels of peak demand risk.

    Full Text Available The 21st Conference of Party (COP21 held in Paris at the end of 2015 has opened a new era for the joint response dealing with climate change globally, and built up a new mode of global climate governance, that is, “all Parties submit INDC – global stocktake – enhance effort of actions – all Parties resubmit INDC – finally achieve the ultimate objective of the Convention.” With 160 INDC reports (covering 188 Parties that the UNFCCC Secretariat has currently received as research objects, this study classifies the mitigation targets of all Parties, and focuses on the systematic analysis of the financial demand, mitigation cost and priority investment areas for developing countries. The results are as follows: among 160 INDC reports, 122 reports clearly include the finance content; 64 reports propose specific amount of financial demand for the implementation of INDC; 31 reports pre-estimate domestic amount and financial demand for greenhouse gas mitigation in 2030, based on which they have calculated that the average mitigation cost for developing countries in 2030 would have reached up to US$22.3 per ton CO2; 28 Parties reclassify the financial demand for mitigation and adaptation areas, and reach the conclusion that the overall financial demand ratio for mitigation and adaptation is 1.4. Should the current mitigation commitments of the Parties from developed countries be used as benchmark, then in 2030 the total amount of financial demand for developing countries in response to climate change would have reached up to US$474 billion.

    Full Text Available Background: In order to track progress towards the target of universal access to sexual and reproductive health care services of the post-2015 Sustainable Development Goals (SDGs, a measure (demand for family planning satisfied with modern contraceptive methods and a benchmark (at least 75% by 2030 in all countries have been recommended. Objectives: The goal of this study was to assess the prospects of reaching the benchmark at the country level. Such information can facilitate strategic planning, including resource allocation at global and country levels. Design: We selected 63 countries based on their status as least developed according to the United Nations or as a priority country in global family planning initiatives. Using United Nations estimates and projections of family planning indicators between 1970 and 2030, we calculated percent demand for family planning satisfied with modern contraceptive methods for each year and country. We then calculated the annual percentage point changes between 2014 and 2030 required to meet the benchmark. The required rates of change were compared to current projections as well as estimates between 1970 and 2010. Results: To reach the benchmark on average across the 63 countries, demand satisfied with modern methods must increase by 2.2 percentage points per year between 2014 and 2030 – more than double current projections. Between 1970 and 2010, such rapid progress was observed in 24 study countries but typically spanning 5–10 years. At currently projected rates, only 9 of the 63 study countries will reach the benchmark. Meanwhile, the gap between projected and required changes is largest in the Central and West African regions, 0.9 and 3.0 percentage points per year, respectively. If the benchmark is achieved, 334 million women across the study countries will use a modern contraceptive method in 2030, compared to 226 million women in 2014. Conclusions: In order to achieve the component of the SDGs

    2015-05-01

    Full Text Available This study aimed to analyze demand for oil in 20 selected OECD countries over the period 1980 to 2011, within the framework of panel data model. The long-run income and price elasticities of oil demand were computed and the Granger causality between variables of interest was tested. The results indicated that oil demand has positive and negative income and price elasticities, respectively. In addition, both income and price were inelastic in the long-run, but price elasticity was lower than income elasticity. Furthermore, a bidirectional causality running from economic growth to oil consumption and vice versa was obtained, providing evidence of feedback hypothesis. Based on these results, some crucial policy implications were suggested

    To evaluate the potential impact and value of applications (e.g. adjusting ordering levels, storage capacity, transportation capacity, distribution frequency) of data from demand forecasting systems implemented in a lower-income country's vaccine supply chain with different levels of population change to urban areas. Using our software, HERMES, we generated a detailed discrete event simulation model of Niger's entire vaccine supply chain, including every refrigerator, freezer, transport, personnel, vaccine, cost, and location. We represented the introduction of a demand forecasting system to adjust vaccine ordering that could be implemented with increasing delivery frequencies and/or additions of cold chain equipment (storage and/or transportation) across the supply chain during varying degrees of population movement. Implementing demand forecasting system with increased storage and transport frequency increased the number of successfully administered vaccine doses and lowered the logistics cost per dose up to 34%. Implementing demand forecasting system without storage/transport increases actually decreased vaccine availability in certain circumstances. The potential maximum gains of a demand forecasting system may only be realized if the system is implemented to both augment the supply chain cold storage and transportation. Implementation may have some impact but, in certain circumstances, may hurt delivery. Therefore, implementation of demand forecasting systems with additional storage and transport may be the better approach. Significant decreases in the logistics cost per dose with more administered vaccines support investment in these forecasting systems. Demand forecasting systems have the potential to greatly improve vaccine demand fulfilment, and decrease logistics cost/dose when implemented with storage and transportation increases. Simulation modeling can demonstrate the potential health and economic benefits of supply chain improvements. Copyright

  17. Demands For Solar Electricity From The BRICS Countries In The Future

    2015-12-01

    BRICS countries are presently among the leading the economic powers globally, but their increasing demands for energy and sustainable future requires renewed technical progress on implementation of renewable energy (e.g., solar energy) and a sustainable solution rather than extracting finite natural resources. BRICS countries (Brazil, Russia, India, China and South Africa) face both social and environmental pressures as their economy keeps growing. The rapid development of technology in BRICS inevitably altered their culture and behavior, as reflected by education, gender equality, health, and other demographic/socio-economic indicators. These changes coupled with land use/land cover change have altered ecosystem services, as reflected by NEE (Net Ecosystem Exchange of CO2) and NDVI (Normalized Difference Vegetation Index). Global climatic changes also drives the demand for sustainable energy. With a focus on solar energy, we analyzed time series of energy consuming behaviors, government policies, and the ecosystem services. Structural equation modeling was applied to confirm the relationships among societal transition, ecosystem services, and climate change. We compared the energy consumption patterns for the five countries and forecasted the changes through 2025. We found that government policies significantly influenced energy consumption behaviors for BRICS and that solar energy usage would continue to increase to 2025 and beyond.

    Over 1.1 billion people in the world lack access to improved drinking water. Diarrhoeal and other waterborne diseases cause an estimated 1.87 million deaths per year. The Safe Water System (SWS) is a household water treatment intervention that reduces diarrhoeal disease incidence among users in developing countries. Turbid waters pose a particular challenge to implementation of SWS programmes; although research shows that a 3.75 mg l(-1) sodium hypochlorite dose effectively treats turbid waters, users sometimes object to the strong chlorine taste and prefer to drink water that is more aesthetically pleasing. This study investigated the efficacy of two locally available chemical water treatments-alum and Moringa oleifera flocculation-to reduce turbidity and chlorine demand at turbidities of 10, 30, 70, 100 and 300 NTU. Both treatments effectively reduced turbidity (alum flocculation 23.0-91.4%; moringa flocculation 14.2-96.2%). Alum flocculation effectively reduced chlorine demand compared with controls at 30, 70, 100 and 300 NTU (p=0.01-0.06). Moringa flocculation increased chlorine demand to the point where adequate free chlorine residual was not maintained for 24 hours after treatment. Alum pretreatment is recommended in waters>or=30 NTU for optimum water disinfection. Moringa flocculation is not recommended before chlorination.

J Strength Cond Res 30(8): 2138-2144, 2016-The purpose was to investigate the relationship between elite females' competitive performance capability in sprint and distance cross-country skiing and the variables of gross efficiency (GE), work rate at the onset of blood-lactate accumulation (OBLA4mmol), maximal oxygen uptake (V[Combining Dot Above]O2max), maximal speed (Vmax), and peak upper-body oxygen uptake (V[Combining Dot Above]O2peak). Ten elite female cross-country skiers (age 24.5 ± 2.8 years) completed treadmill roller-skiing tests to determine GE, OBLA4mmol, and V[Combining Dot Above]O2max using the diagonal-stride technique as well as Vmax and V[Combining Dot Above]O2peak using the double-poling technique. International Ski Federations ranking points for sprint (FISsprint) and distance (FISdist) races were used as competitive performance data. There were correlations between the FISsprint and the V[Combining Dot Above]O2max expressed absolutely (p = 0.0040), Vmax (p = 0.012), and V[Combining Dot Above]O2peak expressed absolutely (p cross-country skiing. In addition, the ability to generate a high Vmax indicates the performance in sprint races, whereas the skier's OBLA4mmol reflects the performance capability in distance races. Based on the results, when evaluating the performance capacity of elite female cross-country skiers, it is recommended to use physiological variables that reflect competitive performance.

    Korea is depending 97% of primary energy consumption on imports. To have a stable supply of energy required for a continuous growth, it is recommended to utilize international energy market actively for short-term while it is required to reinforce resources diplomacy with other countries with full of resources for mid- and long-term. This study reviewed energy supply and demand and major policies of China, Indonesia and Mexico, which give direct or indirect influence on energy supply and demand of Korea. With the geographical adjacency, Korea imports coal from China and exports petroleum products to China. Furthermore, it is very likely to have a trade related to nuclear power plant and natural gas. Indonesia exports coal, crude oil, and LNG to Korea. Especially LNG is occupied 60% of total amount of imports. It is expected to get help from Mexico because there are many similar aspects between Mexico and Korea such as GNP or a conservative idea on energy industry. (author). 49 refs., 6 figs., 42 tabs.

    Tourism industry is the second largest foreign exchange earner after manufacturing in Malaysia. With regards to the importance of tourism industry in Malaysia, any factors that influence tourism demand should be considered cautiously by the government and tourism authorities in order to attract more international tourists in the near future. The purpose of this study is to investigate the dynamic long-run and short-run relationship between the number of international tourist arrivals from six European countries and four selected economic variables. The economic variables used in this study are exchange rate, gross domestic product, relative price and substitute relative price. This study also examines the impact of the European Sovereign crisis on the number of arrivals from the selected European countries to Malaysia. The data covers the period from quarter 1 (Q1) of 1999 to quarter 3 (Q3) of 2014 and employs the autoregressive distributed lag (ARDL) bounds testing approach proposed by Pesaran et al. (2001). The results of unit root test show a mixture of integrated at level and order one, I(0) and I(1). The results show that there exist long-run cointegration between the number of international tourist arrivals and exchange rate, level of income, tourism price and substitute tourism price for all countries. Generally, the results show that level of income is in line with the economic theory and Thailand is a competing destination for the tourism industry in Malaysia. Surprisingly, relative price is found to have positive impact on the number of arrivals to Malaysia and this suggests that an increase in the price level in Malaysia is unexpectedly increase the number of international tourist arrivals to Malaysia. Therefore the Malaysian government and tourism authorities should continue the efforts to withstand the growth of the tourism industry.

    Family planning is crucial for preventing unintended pregnancies and for improving maternal and child health and well-being. In urban areas where there are large inequities in family planning use, particularly among the urban poor, programs are needed to increase access to and use of contraception among those most in need. This paper presents the midterm evaluation findings of the Urban Reproductive Health Initiative (Urban RH Initiative) programs, funded by the Bill & Melinda Gates Foundation, that are being implemented in 4 countries: India (Uttar Pradesh), Kenya, Nigeria, and Senegal. Between 2010 and 2013, the Measurement, Learning & Evaluation (MLE) project collected baseline and 2-year longitudinal follow-up data from women in target study cities to examine the role of demand generation activities undertaken as part of the Urban RH Initiative programs. Evaluation results demonstrate that, in each country where it was measured, outreach by community health or family planning workers as well as local radio programs were significantly associated with increased use of modern contraceptive methods. In addition, in India and Nigeria, television programs had a significant effect on modern contraceptive use, and in Kenya and Nigeria, the program slogans and materials that were blanketed across the cities (eg, leaflets/brochures distributed at health clinics and the program logo placed on all forms of materials, from market umbrellas to health facility signs and television programs) were also significantly associated with modern method use. Our results show that targeted, multilevel demand generation activities can make an important contribution to increasing modern contraceptive use in urban areas and could impact Millennium Development Goals for improved maternal and child health and access to reproductive health for all. © Speizer et al.

    Full Text Available Abstract.  The demand for automobiles has always been an important area for the application of various theoretical econometric models and the automotive industry remains to be the leading export sector in Turkey. This paper surveys a range of important developments in the modeling and estimation of demand for new automobiles in various regions like the U.S., Europe, and Turkey. The applied econometrician can acquire a good perspective when constructing such a model and deciding on the most appropriate econometric estimation technique. However, the applied econometrician is cautioned against some of the difficulties in modeling and forecasting the demand for automobiles. Since the Country of Origin (COO effect is known to be an important factor in explaining the demand for products including automobiles, we also review the marketing literature investigating the consumers’ biases about products related to the country in which they are made.

    The four BRIC countries - Brazil, Russia, India and China - expect to see electricity consumption soar in the next decade attracting investments of USD 4,632 billion up to 2030 for their large-scale infrastructure projects within their power sectors. Inevitably each country has particular requirements and specific areas of priority, however, all four BRIC countries have similarities when it comes to financing power sector investments and ensuring a proper return with high levels of regulatory, political and legal risk present in all four jurisdictions.

  10. Debt-driven growth? Wealth, distribution and demand in OECD countries

    OpenAIRE

    Stockhammer, Engelbert; Wildauer, Rafael

    2015-01-01

    The paper investigates the effects of changes in the distribution of income and in wealth on aggregate demand and its components. We extend the Bhaduri and Marglin (1990) model to include personal income inequality as well as asset prices and debt. This allows for an evaluation of the wage or profit-led nature of demand regimes, of the expenditure cascade argument (Frank et al. 2010) and several hypotheses regarding the effects of wealth and debt. Our estimates are based on a panel of 18 OECD...

    Attempts to maintain or increase vaccination coverage almost all focus on supply side interventions: improving availability and delivery of vaccines. The effectiveness and cost-effectiveness of efforts to increase demand is uncertain. We performed a systematic review of studies that provided quantitative estimates of the impact of demand side interventions on uptake of routine childhood vaccination. We retrieved studies published up to Sept 2008. The initial search retrieved 468 potentially eligible studies, including four systematic reviews and eight original studies of the impact of interventions to increase demand for vaccination. We identified only two randomised controlled trials. Interventions with an impact on vaccination uptake included knowledge translation (KT) (mass media, village resource rooms and community discussions) and non-KT initiatives (incentives, economic empowerment, household visits by extension workers). Most claimed to increase vaccine coverage by 20 to 30%. Estimates of the cost per vaccinated child varied considerably with several in the range of $10-20 per vaccinated child. Most studies reviewed here represented a low level of evidence. Mass media campaigns may be effective, but the impact depends on access to media and may be costly if run at a local level. The persistence of positive effects has not been investigated. The economics of demand side interventions have not been adequately assessed, but available data suggest that some may be very cost-effective.

    To synthesise evidence on the implementation, costs and cost-effectiveness of demand generation interventions and their effectiveness in improving uptake of modern contraception methods. A Cochrane systematic review was conducted. Searches were performed in electronic databases (MEDLINE, EMBASE) and the grey literature. Randomised controlled trials, cluster randomised trials and quasi-experimental studies, including controlled before-after studies (CBAs) and cost and cost-effectiveness studies that aimed to assess demand interventions (including community- and facility-based interventions, financial mechanisms and mass media campaigns) in low- and middle-income countries were considered. Meta-analyses and narrative synthesis were conducted. In total, 20 papers meeting the inclusion criteria were included in this review. Of those, 13 were used for meta-analysis. Few data were available on implementation and on the influence of context on demand interventions. Involving family members during counselling, providing education activities and increasing exposure to those activities could enhance the success of demand interventions. Demand generation interventions were positively associated with increases in current use (pooled OR 1.57; 95% CI: 1.46-1.69, P Demand interventions improved knowledge (pooled OR 1.02; 95% CI 0.63-1.64, P = 0.93) and attitudes towards family planning and improved discussion with partners/husbands around modern contraceptive methods. However, given the limited number of studies included in each category of demand generation interventions, the dates of publication of the studies and their low quality, caution is advised in considering the results. Very limited evidence was available on costs; studies including data on costs were old and inconsistent. Demand generation interventions contribute to increases in modern contraceptive methods use. However, more studies with robust designs are needed to identify the most effective demand generation

    Demand-based estimates of total cannabis consumption rarely consider differences among different user types and variation across countries. To describe cannabis consumption patterns and estimate annual consumption for different user types across EU Member States, a web survey in Bulgaria, Czech Republic, Italy, the Netherlands, Portugal, Sweden and United Kingdom (England & Wales) collected data on cannabis use patterns from 3,922 persons who had consumed cannabis at least once in the past year. They were classified into four groups based on their number of use days in the past 12 months: infrequent users or chippers (users (11-50 days), regular users (51-250 days) and intensive users (>250 days). User type specific data on typical amounts consumed were matched with data on numbers of users per user type estimated from existing population surveys, taking differences in mode of consumption, age and gender into account. Estimates were supplemented with data from populations of problem users to compensate for under coverage. Results showed remarkably consistent differences among user groups across countries. Both the average number of units consumed per typical use day and the average amount of cannabis consumed per unit increased across user types of increasing frequency of use. In all countries except Portugal, intensive users formed the smallest group of cannabis users but were responsible for the largest part of total annual cannabis consumption. Annual cannabis consumption varied across countries but confidence intervals were wide. Results are compared with previous estimates and discussed in the context of improving estimation methods.

    Given the impact of the global economic crisis, delivering better health care with limited finance grows more challenging. Through the lens of institutional theory, this paper explores pressures experienced by hospital leaders to improve quality and constrain spending, focusing on how they respond to these often competing demands. An in-depth, multilevel analysis of health care quality policies and practices in five European countries including longitudinal case studies in a purposive sample of ten hospitals. How hospitals responded to the financial and quality challenges was dependent upon three factors: the coherence of demands from external institutions; managerial competence to align external demands with an overall quality improvement strategy, and managerial stability. Hospital leaders used diverse strategies and practices to manage conflicting external pressures. The development of hospital leaders' skills in translating external requirements into implementation plans with internal support is a complex, but crucial, task, if quality is to remain a priority during times of austerity. Increasing quality improvement skills within a hospital, developing a culture where quality improvement becomes embedded and linking cost reduction measures to improving care are all required. © The Author(s) 2015.

    Global guidelines for new technologies are based on cost and efficacy data from a limited number of trial locations. Country-level decision makers need to consider whether cost-effectiveness analysis used to inform global guidelines are sufficient for their situation or whether to use models that adjust cost-effectiveness results taking into account setting-specific epidemiological and cost heterogeneity. However, demand and supply constraints will also impact cost-effectiveness by influencing the standard of care and the use and implementation of any new technology. These constraints may also vary substantially by setting. We present two case studies of economic evaluations of the introduction of new diagnostics for malaria and tuberculosis control. These case studies are used to analyse how the scope of economic evaluations of each technology expanded to account for and then address demand and supply constraints over time. We use these case studies to inform a conceptual framework that can be used to explore the characteristics of intervention complexity and the influence of demand and supply constraints. Finally, we describe a number of feasible steps that researchers who wish to apply our framework in cost-effectiveness analyses.

    The production and consumption of electricity is a major source of CO{sub 2} emissions in Europe and elsewhere. In turn, the manufacturing sectors are significant end-users of electricity. In contrast to most papers in the literature, which focus on the supply-side, this study tackles the demand-side of electricity. An input-output approach combined with a sensitivity analysis has been developed to analyse the direct and indirect consumptions of electricity by eighteen manufacturing sectors in fifteen European countries, with indirect electricity demand related to the purchase of industrial products from other sectors which, in turn, require the consumption of electricity in their manufacturing processes. We identify the industrial transactions and sectors, which account for a greater share of electricity demand. In addition, the impact of an electricity price increase on the costs and prices of manufacturing products is simulated through a price model, allowing us to identify those sectors whose manufacturing costs are most sensitive to an increase in the electricity price.

    Although it is well known that vaccines against many infectious diseases confer positive economic externalities via indirect protection, analysts have typically ignored possible herd protection effects in policy analyses of vaccination programs. Despite a growing literature on the economic theory of vaccine externalities and several innovative mathematical modeling approaches, there have been almost no empirical applications. The first objective of the paper is to develop a transparent, accessible economic framework for assessing the private and social economic benefits of vaccination. We also describe how stated preference studies (for example, contingent valuation and choice modeling) can be useful sources of economic data for this analytic framework. We demonstrate socially optimal policies using a graphical approach, starting with a standard textbook depiction of Pigouvian subsidies applied to herd protection from vaccination programs. We also describe nonstandard depictions that highlight some counterintuitive implications of herd protection that we feel are not commonly understood in the applied policy literature. We illustrate the approach using economic and epidemiological data from two neighborhoods in Kolkata, India. We use recently published epidemiological data on the indirect effects of cholera vaccination in Matlab, Bangladesh (Ali et al., 2005) for fitting a simple mathematical model of how protection changes with vaccine coverage. We use new data on costs and private demand for cholera vaccines in Kolkata, India, and approximate the optimal Pigouvian subsidy. We find that if the optimal subsidy is unknown, selling vaccines at full marginal cost may, under some circumstances, be a preferable second-best option to providing them for free.

  19. Why Electricity Demand Is Highly Income-Elastic in Spain: A Cross-Country Comparison Based on an Index-Decomposition Analysis

    Julián Pérez-García

    2017-03-01

    Full Text Available Since 1990, Spain has had one of the highest elasticities of electricity demand in the European Union. We provide an in-depth analysis into the causes of this high elasticity, and we examine how these same causes influence electricity demand in other European countries. To this end, we present an index-decomposition analysis of growth in electricity demand which allows us to identify three key factors in the relationship between gross domestic product (GDP and electricity demand: (i structural change; (ii GDP growth; and (iii intensity of electricity use. Our findings show that the main differences in electricity demand elasticities across countries and time are accounted for by the fast convergence in residential per capita electricity consumption. This convergence has almost concluded, and we expect the Spanish energy demand elasticity to converge to European standards in the near future.

  20. Consumer-led demand side financing in health and education and its relevance for low and middle income countries.

    Ensor, Tim

    2004-01-01

    There is increasing awareness that supply subsidies for health and education services often fail to benefit those that are most vulnerable in a community. This recognition has led to a growing interest in and experimentation with, consumer-led demand side financing systems (CL-DSF). These mechanisms place purchasing power in the hands of consumers to spend on specific services at accredited facilities. International evidence in education and health sectors suggest a limited success of CL-DSF in raising the consumption of key services amongst priority groups. There is also some evidence that vouchers can be used to improve targeting of vulnerable groups. There is very little positive evidence on the effect of CL-DSF on service quality as a consequence of greater competition. Location of services relative to population means that areas with more provider choice, particularly in the private sector, tend to be dominated by higher and middle-income households. Extending CL-DSF in low-income countries requires the development of capacity in administering these financing schemes and also accrediting providers. Schemes could focus primarily on fixed packages of key services aimed at easily identifiable groups. Piloting and robust evaluation is required to fill the evidence gap on the impact of these mechanisms. Extending demand financing to less predictable services, such as hospital coverage for the population, is likely to require the development of a voucher scheme to purchase insurance. This suggests an already developed insurance market and is unlikely to be appropriate in most low-income countries for some time.

    Full Text Available This realist review explored causal pathways of the possible consumer effects of health sector demand-side financial (DSF incentives, their contextual factors and mechanisms in low-and-middle-income countries. We searched six electronic data bases and identified 659 abstracts with different evaluation designs. Based on methodological rigor and content relevance, only 24 studies published up to April 2013 were selected for the final review. A conceptual framework consisting of various program theories on potential context-mechanism-outcome (C-M-O configuration of DSF initiative was designed, tested and adapted during the review. Synthesized results were presented as a C-M-O configuration for each of the consumer-side effect. DSF was effective to improve health seeking behaviour considerably and health status to some extent. The causal pathway of DSF’s functioning and effectiveness was not linear. Key demand-side contextual factors which affected DSF’s consumer-side effects were background characteristics of the beneficiaries including their socio-cultural beliefs, motivations, and level of health awareness. At the supply-side, service availability status and provider incentives were contextual determinants. The mechanisms which enabled the interaction of contextual influence were consumer and provider accountability and consumer trust on providers. In order to enhance DSF programs’ effectiveness, their design and implementation should carefully consider the potential contextual elements that may influence the causal pathways.

    A Typhoid Conjugate Vaccine (TCV) is expected to acquire WHO prequalification soon, which will pave the way for its use in many low- and middle-income countries where typhoid fever is endemic. Thus it is critical to forecast future vaccine demand to ensure supply meets demand, and to facilitate vaccine policy and introduction planning. We forecasted introduction dates for countries based on specific criteria and estimated vaccine demand by year for defined vaccination strategies in 2 scenarios: rapid vaccine introduction and slow vaccine introduction. In the rapid introduction scenario, we forecasted 17 countries and India introducing TCV in the first 5 y of the vaccine's availability while in the slow introduction scenario we forecasted 4 countries and India introducing TCV in the same time period. If the vaccine is targeting infants in high-risk populations as a routine single dose, the vaccine demand peaks around 40 million doses per year under the rapid introduction scenario. Similarly, if the vaccine is targeting infants in the general population as a routine single dose, the vaccine demand increases to 160 million doses per year under the rapid introduction scenario. The demand forecast projected here is an upper bound estimate of vaccine demand, where actual demand depends on various factors such as country priorities, actual vaccine introduction, vaccination strategies, Gavi financing, costs, and overall product profile. Considering the potential role of TCV in typhoid control globally; manufacturers, policymakers, donors and financing bodies should work together to ensure vaccine access through sufficient production capacity, early WHO prequalification of the vaccine, continued Gavi financing and supportive policy.

    Recent forecasts of dengue travel vaccine demand, while worthy, might be improved by modelling future travel flows, and by accounting for incremental reductions in demand at the different points in the sequence of events leading to travel vaccine purchase. In particular, we suggest that an alternative method of projecting dengue travel vaccine uptake would account for (1) future flows of travellers from all non-endemic source to all endemic destination countries, based on data that are comparable between countries, and corrected for double-counting and other sources of error; (2) the proportion of such travellers that seek premedical travel advice within a timescale compatible with the probable dengue vaccine schedule; (3) the proportion of these travellers that will present with a combination of risk factors (above and beyond destination country) sufficient to prompt a physician to prescribe a dengue vaccine; and (4) the proportion of these travellers that actually purchase a vaccine when advised to do so.

    Achieving food security in an environmentally sustainable manner is one of the biggest challenges of our time. Using insects as food can serve this purpose because they are nutritionally valuable and environmentally friendly. Embracing insects as food requires information on potential consumer...... demand as this would determine the success of product development. In this study, we present one of the first thorough assessments of consumer demand for an insect-based food. We assessed the demand in terms of Kenyan consumer preferences and willingness to pay for buns containing varying amounts...... market shares than standard buns. Results also suggested that a market for breads made with cricket flour is likely in Kenya since the demand is present. This signals that insect-based food products may serve as a viable and demand-driven way to increase food security in Kenya in the future....

  8. Health care utilization patterns in developing countries: role of the technology environment in "deriving" the demand for health care.

    Science.gov (United States)

    Wouters, A V

    1992-01-01

    Health care services, in combination with several intermediate (proximate) determinants of health such as environmental sanitation and nutrition, directly influence health status. In the economics literature, this is referred to as the health production technology. Although many studies recognize that demand for health care depends on the health production technology, otherwise known as a "derived" demand, this review indicates that few of them have so far been able to fully incorporate this technology in estimating significant determinants of health care use. Understanding the technology environment could help explain why substantial portions of the population do not gain access to care even when financial factors do not appear to be a barrier. Also, low utilization of health services may simply reflect the low productivity of these services when other complementary factors such as nutrition or clean water and sanitation are lacking. Finally, since health-producing technology is often a multistep (multivisit) process, health care demand studies generally offer an incomplete picture of health care utilization patterns because they focus on a single event such as the first visit of an illness episode. Researchers should obtain more complete information on the interaction between all health production inputs, their availability and access to them. Multidisciplinary methodologies are likely to be useful.

  9. The tourism consumption, a special economic category of the final demand in Albania and in the countries of the region

    Full Text Available Tourism is an international activity which includes a combination of economic, political, environmental and social factors whose consequences are becoming more and more complex, controversial and which emerge in delicate and unexpected ways. Today tourism is characterized by a development which is not only continuous but also sensitive to rapidly-changing attitudes. The effects of tourism are multifaceted: economic, social, natural or environmental, political, and cultural. In this article we will talk about the effects of the development of tourism on the international and total tourism consumption regarding Albania accompanied with empirical data and a comparison of their respective statistics. We will also try to study the effect of financial crisis on the international tourism consumption in Albania. All the data have been collected from INSTAT and Travel & Tourism Economic Impact 2012, for the time period 2006-2012. The number of visitors to Albania after 2000 has been increasing and consequently the positive impact of tourism on total consumption has become stronger. Nevertheless, after 2006, Albania shows strong fluctuations in tourism consumption compared to other countries in the region. This is due to the fact that Albania is a relatively new destination in the development of tourism market.

    In many countries financing for health services has traditionally been disbursed directly from governmental and non-governmental funding agencies to providers of services: the 'supply-side' of healthcare markets. Demand-side financing offers a supplementary model in which some funds are instead channelled through, or to, prospective users. In this review we considered evidence on five forms of demand-side financing that have been used to promote maternal health in developing countries: OBJECTIVES: The overall review objective was to assess the effects of demand-side financing interventions on maternal health service utilisation and on maternal health outcomes in low- and middle-income countries. Broader effects on perinatal and infant health, the situation of underprivileged women and the health care system were also assessed. This review considered poor, rural or socially excluded women of all ages who were either pregnant or within 42 days of the conclusion of pregnancy, the limit for postnatal care as defined by the World Health Organization. The review also considered the providers of services.The intervention of interest was any programme that incorporated demand-side financing as a mechanism to increase the consumption of goods and services that could impact on maternal health outcomes. This included the direct consumption of maternal health care goods and services as well as related 'merit goods' such as improved nutrition. We included systems in which potential users of maternal health services are financially empowered to make restricted decisions on buying maternal health-related goods or services - sometimes known as consumer-led demand-side financing. We also included programmes that provided unconditional cash benefits to pregnant women (for example in the form of maternity allowances), or to families with children under five years of age where there was evidence concerning maternal health outcomes.We aimed to include quantitative studies (experimental

    Demand-side financing, where funds for specific services are channelled through, or to, prospective users, is now employed in health and education sectors in many low- and middle-income countries. This systematic review aimed to critically examine the evidence on application of this approach to promote maternal health in these settings. Five modes were considered: unconditional cash transfers, conditional cash transfers, short-term payments to offset costs of accessing maternity services, vouchers for maternity services, and vouchers for merit goods. We sought to assess the effects of these interventions on utilisation of maternity services and on maternal health outcomes and infant health, the situation of underprivileged women and the healthcare system. The protocol aimed for collection and synthesis of a broad range of evidence from quantitative, qualitative and economic studies. Nineteen health and social policy databases, seven unpublished research databases and 27 websites were searched; with additional searches of Indian journals and websites. Studies were included if they examined demand-side financing interventions to increase consumption of services or goods intended to impact on maternal health, and met relevant quality criteria. Quality assessment, data extraction and analysis used Joanna Briggs Institute standardised tools and software. Outcomes of interest included maternal and infant mortality and morbidity, service utilisation, factors required for successful implementation, recipient and provider experiences, ethical issues, and cost-effectiveness. Findings on Effectiveness, Feasibility, Appropriateness and Meaningfulness were presented by narrative synthesis. Thirty-three quantitative studies, 46 qualitative studies, and four economic studies from 17 countries met the inclusion criteria. Evidence on unconditional cash transfers was scanty. Other demand-side financing modes were found to increase utilisation of maternal healthcare in the index

    This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of uncertainty resolution found in productivity heterogeneity models...... the high rate of exit seen in the first years of exporting. Finally, when faced with multiple countries in which to export, some firms will choose to sequentially export in order to slowly learn more about its chances for success in untested markets....

    Full Text Available Demand-side innovation policies, in the form of regulations, public procurement, subsidies for private demand, and other measures, are often viewed as valuable additions to more traditional supply-side policies. The demand-side innovation policies should enable to facilitate the emergence of vital and sustainable links between innovation outputs and various markets. However, without sufficient institutional framework and policy experiences such measures could also contribute to new market distortions or crowding-out effects, which do not facilitate sustainable growth in innovations. The charting of possible risks of such policies should help to outline the criteria for aiming at sustainable effects. The purpose of this contribution is to offer suggestions about preconditions and policy characteristics, which should help to avoid the misuse of demand-side measures and facilitate the sustainability of desired changes in society. It is predominantly conceptual contribution but draws also extensively on case evidence about the effects of relevant policies and their discontinuation

    Full Text Available The similarity coefficients of the export structures of Romania, Croatia, Serbia and Bosnia-Herzegovina and the import structure of the EU and the U.S. have increased since 2000, but to date, they have not reached a critical turning point. This indicates that the qualities of exports from the observed transitional economies have not rapidly improved, and the export structure remains relatively unfavourable, particularly when compared to advanced transitional countries. The most important factors in the success of advanced transitional economies were: the inflow of foreign direct investment, imports of modern technology (and later, their own development, innovation, development of small and medium sized enterprises, foreign competition, the development of a market economy and macroeconomic stability. The export structures of Romania, Croatia, Serbia and Bosnia correlate with improvement in the process of transition in the observed countries. In 2009 Bosnia had the absolute lowest level of similarity coefficient among the studied countries, followed by Serbia, Romania and Croatia, which corresponds to the overall economic performance and foreign trade of the observed economies.

  20. How countries cope with competing demands and expectations: perspectives of different stakeholders on priority setting and resource allocation for health in the era of HIV and AIDS

    Full Text Available Abstract Background Health systems have experienced unprecedented stress in recent years, and as yet no consensus has emerged as to how to deal with the multiple burden of disease in the context of HIV and AIDS and other competing health priorities. Priority setting is essential, yet this is a complex, multifaceted process. Drawing on a study conducted in five African countries, this paper explores different stakeholders′ perceptions of health priorities, how priorities are defined in practice, the process of resource allocation for HIV and Health and how different stakeholders perceive this. Methods A sub-analysis was conducted of selected data from a wider qualitative study that explored the interactions between health systems and HIV and AIDS responses in five sub-Saharan countries (Burkina Faso, the Democratic Republic of Congo, Ghana, Madagascar and Malawi. Key background documents were analysed and semi-structured interviews (n = 258 and focus group discussions (n = 45 were held with representatives of communities, health personnel, decision makers, civil society representatives and development partners at both national and district level. Results Health priorities were expressed either in terms of specific health problems and diseases or gaps in service delivery requiring a strengthening of the overall health system. In all five countries study respondents (with the exception of community members in Ghana identified malaria and HIV as the two top health priorities. Community representatives were more likely to report concerns about accessibility of services and quality of care. National level respondents often referred to wider systemic challenges in relation to achieving the Millennium Development Goals (MDGs. Indeed, actual priority setting was heavily influenced by international agendas (e.g. MDGs and by the ways in which development partners were supporting national strategic planning processes. At the same time, multi

    The electricity has become a strategic support for the operation of the societies in its group, because it is being used intensively in the production, transport, communication, administration, science, education and the daily life through the personal computer, for what we can affirm that the electricity is in full expansion. Nevertheless, at the present time more of half of petroleum consumed in the world it is used for the terrestrial, air and marine transport. Many texts have been published in energy that they remind that the success of an industrial society, the growth of their economy, the quality of their inhabitants life and their impact in other societies and in the environment they are largely determined by the quantity and class of energy sources that it exploits and for the effectiveness of their systems to transform the potential energy into work and heat. In this work we observe tendencies in the energy consumption of 21 countries with complete conscience that the energy situation of each one of them depends, in first place, of the availability of its energy resources and its costs, besides its energy politicians, its laws and its maneuver margins. This way, the effect of the interrelations that here are analyzed for the period 1980-2004, is illustrated by means of a comparison of the energy consumption per capita in each one of those 21 countries. The work is very illustrative not alone regarding the inequality in the energy consumption in the world, moreover it mentions that countries are those that have the control of the world energy resources and it detects others that are participating actively in that battle by means of the use of new technologies and equipment s that seek to look for a bigger energy efficiency and to impel low economies in carbon and not based on fossil fuels.

    Focusing on the present status and future of coal demand in Central/South American countries and the coal trade between Central/South American countries and the U.S., the paper described the present status and future of coal demand there and the effects on Japan. Export of Colombian coal will amount to approximately 30-35 million tons in 2000. Venezuelan coal 10-20 million tons. The U.S. imported good-quality general coal low in sulfur content, 3.08 tons from Columbia and 1.39 tons from Venezuela. Coal export from the U.S. to Central/South America was mostly of raw material coal, 5 million tons in 1993 and 5.39 million tons in 1994. General coal was 180,000 tons. The U.S. has no plans of increasing US coal export to Central/South America. But it is safely predicted that Columbia and Venezuela will increase coal export to Europe in the future. It will bring about decrease in export of US coal to Europe, which connects with increasing pressure for the coal trade amount of Japan. 21 figs., 47 tabs.

    1986-02-01

    In most newly independent African countries, medical care imitates the Western model, with large urban hospitals containing much of the health care personnel and equipment. A decline in the availability of funds for training and facilities, and the appearance of new diseases provoked by industrialization led to the decline of both the quality and the quantity of medical care, especially in rural areas. In the 1970s, a number of African nations developed a network of ambulatory health facilities and village health workers, thus instituting a Primary Health Care System (PHC-System). Due to logistical and supervisory problems, however, these networks often disintegrated after foreign professionals and administrators departed. They are, nevertheless, prerequisites for the gradual improvement of the health care of rural populations in developing countries. Two basic requirements for their establishment and development are a relatively large personnel and financial investment, and the continuous counselling and supervision of trained nonprofessionals. The tasks which these health workers learn and eventually perform over a 1-2 year period include preventive medicine, counselling patients, providing medicines, reporting to responsible clinics, family planning, child care, and the treatment of a variety of diseases. Preventive measures in the framework of PHC Systems encompass 2 principle areas of hygiene, i.e., provision of clean drinking water and proper disposal of human and other wastes; and innoculations. Providing family planning information is a principle duty of the village health workers. To satisfy minimal rural health care and prevention requirements, regional medical centers serving an area of radius 100 to 150 km are needed to train the village health workers, provide basic medicines, and supply medicine and professional medical supervision to the ambulatory centers.

    Full Text Available Emergency contraception pills (ECP are among the 13 essential commodities in the framework for action established by the UN Commission on Life-Saving Commodities for Women and Children. Despite having been on the market for nearly 20 years, a number of barriers still limit women's access to ECP in low- and middle-income countries (LMIC including limited consumer knowledge and poor availability. This paper reports the results of a review to synthesise the current evidence on service delivery strategies to improve access to ECP.A narrative synthesis methodology was used to examine peer reviewed research literature (2003 to 2013 from diverse methodological traditions to provide critical insights into strategies to improve access from a service delivery perspective. The studies were appraised using established scoring systems and the findings of included papers thematically analysed and patterns mapped across all findings using concept mapping.Ten papers were included in the review. Despite limited research of adequate quality, promising strategies to improve access were identified including: advance provision of ECP; task shifting and sharing; intersectoral collaboration for sexual assault; m-health for information provision; and scale up through national family planning programs.There are a number of gaps in the research concerning service delivery and ECP in LMIC. These include a lack of knowledge concerning private/commercial sector contributions to improving access, the needs of vulnerable groups of women, approaches to enhancing intersectoral collaboration, evidence for social marketing models and investment cases for ECP.

    In the context of forming common markets, border areas require special attention, since they anticipate the effects of integration processes. Along borders, different political, monetary, security, and social systems coexist; the intensification of flows resulting from integration raises challenges for the health systems, requiring specific policies focused on guaranteeing the right to health. This article presents the results of a study on the conditions for access to (and demands for) health services in the MERCOSUR border cities. A survey was performed with municipal health secretaries in the 69 Brazilian cities in the States of Rio Grande do Sul, Santa Catarina, Paraná, and Mato Grosso do Sul that border on the other MERCOSUR countries. The study attempted to identify the services demanded by the border population, mechanisms used for access, flows between services and systems, response strategies, and local agreements. Initiatives for cooperation between Brazilian and foreign local administrators were identified in nearly half of the municipalities and can orient the formulation of guidelines for border situations, allowing improvement in comprehensive access to health care.

    This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of uncertainty resolution found in productivity heterogeneity models...... in untested destinations. The option to forecast demands causes firms to delay exporting in order to gather more information about foreign demand. Third, since uncertainty is resolved after entry, many firms enter a destination and then exit after learning that they cannot profit. This prediction reconciles...

    New Zealand is a little country with a little economy but with a population that's rapidly aging. New Zealand's population is only 4.3 million people. It's GDP is only $US58.6 billion (2002). New Zealand's expenditure on health as a percentage of GDP is not out of line with that of other countries. As a nation we have been increasing expenditure on health over recent years. In 1990 we spent 7% of GDP on health. In 1995 that increased to 7.65% and is now 8.3%. However, in per capita terms our expenditure on health does not compare so well with like countries. The size of New Zealand's economy is restricting what our country spends on health. Health is already the second highest demand on the New Zealand tax dollar. The tolerance of New Zealanders would be challenged if a Government attempted to increase taxes further to meet the growing demands for expenditure on health, but at the same time the population's expectations are increasing. This is the challenging situation we face today. What lies ahead? Like all industrialized countries New Zealand is facing an aging population. The population below age 40 is decreasing, but it is increasing significantly over that age. 16% of the population is currently aged over 60. By 2051 this proportion will almost double to just over 31%. Coupled with the aging population is increased awareness and expectations, as access to options for treatment and technology becomes readily accessible to the population through such media as the internet. The extent of the impact of the aging population can be clearly represented by focusing on one specialty such as orthopaedics. The New Zealand Orthopaecic Association undertook a study in July 2003 which concluded (among other things) that as a result of the projected aging of the population, over the next 50 years: Musculo-skeletal operations will increase by over 30%. The number of hip replacements will nearly double. The incidence of osteoporosis will increase by a massive 201%. The number

    2014-01-01

    This book examines the reasons why various groups around the world choose not to adopt broadband services and evaluates strategies to stimulate the demand that will lead to increased broadband use. It introduces readers to the benefits of higher adoption rates while examining the progress that developed and emerging countries have made in stimulating broadband demand. By relying on concepts such as a supply and demand gap, broadband price elasticity, and demand promotion, this book explains differences between the fixed and mobile broadband demand gap, introducing the notions of substitution and complementarity between both platforms. Building on these concepts, ‘Driving Demand for Broadband Networks and Services’ offers a set of best practices and recommendations aimed at promoting broadband demand.  The broadband demand gap is defined as individuals and households that could buy a broadband subscription because they live in areas served by telecommunications carriers but do not do so because of either ...

    2010-09-27

    This paper surveys the theoretical literature on the relationship between income distribution and food demand, and identifies main gaps of current food modelling techniques that affect the accuracy of food demand projections. At the heart of the relationship between income distribution and food demand is Engel's law. Engel's law establishes that as income increases, households' demand for food increases less than proportionally. A consequence of this law is that the particular shape of the distribution of income across individuals and countries affects the rate of growth of food demand. Our review of the literature suggests that existing models of food demand fail to incorporate the required Engel flexibility when (i) aggregating different food budget shares among households; and (ii) changing budget shares as income grows. We perform simple simulations to predict growth in food demand under alternative income distribution scenarios taking into account nonlinearity of food demand. Results suggest that (i) distributional effects are to be expected from changes in between-countries inequality, rather than within-country inequality; and (ii) simulations of an optimistic and a pessimistic scenario of income inequality suggest that world food demand in 2050 would be 2.7 per cent higher and 5.4 per cent lower than distributional-neutral growth, respectively.

    With several countries currently building nuclear power plants and planning the construction of more to meet long-term increases in electricity demand, uranium resources, production and demand remain topics of notable interest. In response to the projected growth in demand for uranium and declining inventories, the uranium industry – the first critical link in the fuel supply chain for nuclear reactors – is boosting production and developing plans for further increases in the near future. Strong market conditions will, however, be necessary to trigger the investments required to meet projected demand. The "Red Book", jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is a recognised world reference on uranium. It is based on information compiled in 40 countries, including those that are major producers and consumers of uranium.

    Antonio Donizette de Oliveira

    2011-03-01

    Full Text Available The objective of this study is to estimate for several importing countries of fiberboard panels the income elasticities and price elasticities of total import demand and also the own-price and cross-price elasticities of demand for fiberboard panels, differentiated by country of origin. Time series data were used referring to the trade flow of the world’s largest exporters and importers of fiberboard panels. The demand model being used treats products as imperfect substitutes. It was concluded that in Germany, China and United Kingdom the total import demand for fiberboard panels was more sensitive to variations in price than in income, whereas in other importing countries the reverse happened. The own-price elasticity of demand for fiberboard panels, differentiated by country of origin, was higher than one in almost all markets, except in Germany and United Kingdom. The negative cross-price elasticities suggest that fiberboard panels imported from other exporting countries are complementary products.

    Full Text Available This study aimed at analyzing the international pulp market, taking into account themain exporting countries and importing regions, with the objective of estimating, for each market, theown-price and cross-price elasticity in relation to the demand of the pulp, differentiated for country oforigin. The model considers that imports are differentiated by origin; therefore they are not perfect substitutes. The demand from Europe, North America and the Rest of the World for the pulp from theUnited States,Canada, Sweden, Finland, Portugal and Brazil was inelastic. The Asian demand for thissome pulp was elastic. Europe and the Rest of the World showed negative cross-price elasticity, i. e.,and the imported pulp from other countries are complementary products. North America and Asiashowed positive crow-price elasticity, i. e., they consider the pulp produced in other countries assubstitute products. The net effect of the variation on the price of pulp in a country h, over the amountof pulp that goes to the region i depends on the matching of values related to the elasticity ofsubstitution and the price elasticity of the total demand.

We found that the consumption of dairy products depended on whether the household was rural or urban, the region of the country (viz. North, Centre, South) and the household poverty status. The results also show that the demand for fresh and powdered milk, butter and margari...

    The global energy demand depends on supplies from fossil fuels responsible for climate change. The supply of the fossil fuels required to meet the global energy demand depends on production from the available proved reserves of oil, coal and gas unevenly distributed around the world. On the other hand, the energy demand of a country is determined by its economic growth and population dynamics. The industrialised nations accounted for the rising demand in global primary energy. However, a glob...

    the demand-side of markets in the simplest possible way. This strategy has allowed a gradual increase in the sophistication of supply-side aspects of economic evolution, but the one-sided focus on supply is facing diminishing returns. Therefore, demand-side aspects of economic evolution have in recent years...... received increased attention. The present paper argues that the new emphasis on demand-side factors is quite crucial for a deepened understanding of economic evolution. The major reasons are the following: First, demand represents the core force of selection that gives direction to the evolutionary process....... Second, firms' innovative activities relate, directly or indirectly, to the structure of expected and actual demand. Third, the demand side represents the most obvious way of turning to the much-needed analysis of macro-evolutionary change of the economic system....

    Demand response (DR) is a load management tool which provides a cost-effective alternative to traditional supply-side solutions to address the growing demand during times of peak electrical load. According to the US Department of Energy (DOE), demand response reflects “changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized.” 1 The California Energy Commission (CEC) defines DR as “a reduction in customers’ electricity consumption over a given time interval relative to what would otherwise occur in response to a price signal, other financial incentives, or a reliability signal.” 2 This latter definition is perhaps most reflective of how DR is understood and implemented today in countries such as the US, Canada, and Australia where DR is primarily a dispatchable resource responding to signals from utilities, grid operators, and/or load aggregators (or DR providers).

    20世纪90年代以来,随着全球化进程的加速,OECD 国家失业率居高不下、低质量就业日渐增多、收入分配调节弱化。在此背景下,高等教育对个体的重要性不断增强,接受高等教育可能预示着更多的就业机会、更高的就业质量、更高的收入水平以及更高的生活质量,这导致了个体高等教育需求的强化。社会上日益增长的教育需求成为驱动高等教育规模扩张的基本动力。%Since the 1990s, with the acceleration of globalization, OECD countries have experienced high unemployment rate, increasing number of low quality employment and weakening regulation of income distribution; In this context, higher education becomes more and more important to individuals, because the access to higher education means more employment opportunities, higher employment quality, more income and higher quality of life., which leads to the strength of individual demand on higher education. The growing education demand constitutes the fundamental driving force of higher education expansion.

  13. Living with the extreme demand

    2013-05-01

    Full Text Available Most of the ethical literature on extreme poverty suggests, that some, if not most, of the incomes of the residents of rich countries ought to be donated to the global poor. Yet complying with this ethical demand becomes increasingly more difficult as the changes in lifestyle in the (postindustrial north demand ever more consumption in order to obtain the necessities for survival in such societies. In this article, I will discuss Peter Singer's famous arguments for the ethical duty to donate one's possessions, and elaborate the conception of needs prevalent in both Singer's theory and the theories of many of his critics. My argument is that we have to recognise a category of needs called 'social necessities' that are neither luxuries nor basic needs. This leads to two main conclusions: first, the space for ethical deliberation on whether to donate to life-saving purposes is socially conditioned; and second, ethical strategies of redistribution ought to be accompanied with institutional changes, which also concern the conditions in wealthy countries.http://dx.doi.org/10.5324/eip.v7i1.1791

    2017-05-01

    Using a household survey conducted in 2014, this study estimates price elasticity of demand (PED) for beer, country liquor and spirits in India. Ordinary least-square models were used to estimate the responsiveness in alcohol demand due to price change. A large number of control variables were included to adjust for potential confounding in the model. Inter-district variation in alcohol consumption is adjusted for by including district fixed effects. Alcohol prices are negatively associated with demand for alcoholic beverages. The PED ranged from -0.14 for spirits to -0.46 for country liquor. Low level of education was positively associated with spirits consumption. The magnitude of elasticity varied by rural-urban, education and gender. Results indicate that a policy mix of price controls and awareness campaigns would be most effective in tackling the adverse effects of harmful drinking in India. The demand for beer, country liquor and spirits is negatively associated with its own price. The elasticity estimates ranged from -0.14 for spirits to -0.44 for country liquor. The elasticity estimates varied by rural-urban, gender and by education levels of the drinkers.

    This article focuses on causality in demand. A methodology where causality is imposed and tested within an empirical co-integrated demand model, not prespecified, is suggested. The methodology allows different causality of different products within the same demand system. The methodology is applied...... to fish demand. On the German market for farmed trout and substitutes, it is found that supply sources, i.e. aquaculture and fishery, are not the only determinant of causality. Storing, tightness of management and aggregation level of integrated markets might also be important. The methodological...... implication is that more explicit focus on causality in demand analyses provides improved information. The results suggest that frozen trout forms part of a large European whitefish market, where prices of fresh trout are formed on a relatively separate market.

    A rapid increase in the economy, population, industrialization, and urbanization of Asian countries has driven the fast development of their meat industries over recent decades. This consistent increase in meat production and consumption in Asia has been the major cause for the development of the global meat industry. Meat production methods and consumption are very diverse across different regions and countries in Asia, and thus, it is impossible to cover the technological demands of all Asian countries in this review. Here, we have mainly highlighted the differences in meat production methods and consumption in Asia during recent decades and the meat technology demands of three east Asian countries, namely China, Korea, and Japan, and one south Asian country, India. A brief introduction of the meat industry, in particular the production and consumption trend in these countries, is provided in this article. The technology demands for fresh and processed meat products are then reviewed. Copyright © 2017. Published by Elsevier Ltd.

  5. Asymmetries of Demand for Money Functions Amongst EMU Countries

    Full Text Available El Banco Central Europeo (BCE emplea “dos pilares” estratégicos para lograr su objetivo de estabilidad de precios dentro la zona del euro. Aun en ausencia de un objetivo monetario explicito, la estabilidad de la relación entre el dinero y los precios mantiene los efectos del papel de los agregados monetarios en la conducción de la política monetaria. La estabilidad de la relación dinero-precios depende a la larga de las propiedades de la demanda por dinero. Este artículo se ocupa de las funciones de la demanda por dinero en los distintos países de la Unión Monetaria Europea, de si tales funciones de demanda pueden ser identificadas, y en caso de que lo sean, si las funciones serán similares en los diferentes países. Un cambio en la tasa de interés del BCE provocaría un cambio idéntico en la tasa de interés en el corto plazo para todos los países de la Unión. Como una consecuencia, el costo de prestar podría además cambiar, lo cual afectará la demanda de préstamos del banco. El tamaño del efecto resultante puede variar de país a país, dependiendo del marco institucional, y ello puede dar lugar a asimetrías en los mecanismos monetarios. Los autores encuentran diferencias significativas en la semi-elasticidad de la tasa de interés de país a país dentro de la Unión: los autores argumentan que esto puede ocasionar serios problemas en la conducción de la política monetaria común por parte del BCE.

    This study develops econometric models of residential demands for electricity, natural gas, and petroleum products. Fuel demands per household are estimated as functions of fuel prices, per capita income, heating degree days, and mean July temperature. Cross-sectional models are developed using a large data base containing observations for each state and year from 1951 through 1974. Long-run own-price elasticities for all three fuels are greater than unity with natural gas showing the greatest sensitivity to own-price changes. Cross-price elasticities are all less than unity except for the elasticity of demand for oil with respect to the price of gas (which is even larger than the own-price elasticity of demand for oil). The models show considerable stabiity with respect to own-price elasticities but much instability with respect to the cross-price and income elasticities.

  14. Prospects for European labour demand.

    Science.gov (United States)

    Lindley, R M

    1988-07-01

    The impact of economic and technological trends upon the level and structure of labor demand is examined, exploring the methods used to model the labor market and making special reference to demography and technology. Evidence on recent and prospective changes in labor demand is reviewed for France, Germany, Italy, the Netherlands, and the UK. The models used to explore future employment scenarios usually fail to incorporate the linkages required to fully analyze the various demographic-economic interactions. Further, this is not generally viewed as a limitation, given the time frame of most employment projections and their preoccupation with changes in the structure of labor demand. Medium-term multisectoral models tend to pay more attention to both demographic and technical change, but the treatment of both aspects is limited. The projections provide a framework for considering how both socioeconomic behavior and policy might change to achieve different outcomes. The greater a model's behavioral content, as expressed in its relationships between different variables, the greater the insight obtainable from simulation exercises. The 1st half of the 1970s was characterized by a reduction in German employment, representing the severest of European reactions to the oil crisis. The 2nd half of the decade recorded rapid growth in Italy and the Netherlands. The 1980s started with marked declines in Germany and the UK. Overall, the net gains of the 1970s were lost in the recession following the 2nd oil crisis. In none of the 5 countries studied does any realistic prospect emerge of achieving full employment before 2000. The most optimistic outcome is that unemployment will decline only slowly, it at all. The growth of both new forms and areas of employment will not compensate sufficiently for the loss of jobs elsewhere and the growth of labor supply. The industrial sector will continue to experience change in favor of the service sector but at a slower rate than during

    Directory of Open Access Journals (Sweden)

    VĂDUVA MARIA

    2014-08-01

    Full Text Available Studying the consumer’s behavior by the ordinal approach of utility with the help of indifference curves allows us to deduce the two “movement laws of demand” in this chapter: the demand for a “normal” good is decreasing function of its price and an increasing function of income. We will use the elasticity concept to measure the intensity of the relation that is established between the demand, on the one hand, and prices or income, on the other hand: elasticity – price, direct and crossed, and elasticity – income. We can classify the goods in many categories, depending on the values that this elasticity takes. The demand elasticity can be determined depending on price and income. It reflects the proportion in which the demand for different products changes with the modification of the consumers’ income, the other factors remaining constant. The elasticity compared to the income is a demonstration of legality from the consumer’s sphere, which determines a certain hierarchy of the needs of each population category in a certain level of income. The movement of prices orients both the options and decisions of producers, namely the most useful productions and the most efficient investments, as well as the consumers’ options and decisions on the most advantageous buying of goods and services that they need. The prices appear as a “signal system” coordinating and making coherence the economic agents’ decisions – producers, consumers and population.

    The need to apply transportation system management, to developing countries is urgent. Attempts to alleviate severe traffic congestion in their metropolises have so far failed to provide adequate solutions. The countries are faced with many difficulties because of the lack of sufficient financial resources together with their complex internal administrative and political problems. They are incapable of providing sufficient road space to cope with the escalating demand in private automobiles. This has led to excessive delays in urban traveling, environmental pollution problems, decline of road-based public transit services and deterioration of the quality of life in these metropolises. Demand management, in use for decades in the Western world, has also been recognized in Singapore`s famous area licensing scheme (ALS) making other Southeast Asian Metropolises aware of its advantages as an alternative in solving their chaotic traffic problems. However, realization is far different from implementation and still many metropolises are not able to apply the technique. Singapore and Thailand, two leaders among many other Southeast Asian regions in economics, tourism, trade and industry handle their problems far differently, especially the traffic congestion problem. While a number of demand management schemes have been implemented successfully in Singapore since 1975, Bangkok is still struggling to implement such measures to alleviate severe traffic congestion problems. This article intends to high light the successful practices and unsuccessful attempts of demand management techniques applied in Singapore and Bangkok.

  8. Demand surge following earthquakes

    Olsen, Anna H.

    2012-01-01

    Demand surge is understood to be a socio-economic phenomenon where repair costs for the same damage are higher after large- versus small-scale natural disasters. It has reportedly increased monetary losses by 20 to 50%. In previous work, a model for the increased costs of reconstruction labor and materials was developed for hurricanes in the Southeast United States. The model showed that labor cost increases, rather than the material component, drove the total repair cost increases, and this finding could be extended to earthquakes. A study of past large-scale disasters suggested that there may be additional explanations for demand surge. Two such explanations specific to earthquakes are the exclusion of insurance coverage for earthquake damage and possible concurrent causation of damage from an earthquake followed by fire or tsunami. Additional research into these aspects might provide a better explanation for increased monetary losses after large- vs. small-scale earthquakes.

    Existing methods are inadequate for developing aggregate (regional and global) and long-term (several decades) passenger transport demand scenarios, since they are mainly based on simple extensions of current patterns rather than causal relationships that account for the competition among transport modes (aircraft, automobiles, buses and trains) to provide transport services. The demand scenario presented in this paper is based on two empirically proven invariances of human behavior. First, transport accounts for 10 to 15 percent of household total expenditures for those owning an automobile, and around 5 percent for non-motorized households on average (travel money budget). Second, the mean time spent traveling is approximately one hour per capita per day (travel time budget). These two budgets constraints determine the dynamics of the scenario: rising income increases per capita expenditure on travel which, in turn, increase demand for mobility. Limited travel time constraints travelers to shift to faster transport systems. The scenario is initiated with the first integrated historical data set on traffic volume in 11 world regions and the globe from 1960 to 1990 for all major modes of motorized transport. World average per capita traffic volume, which was 1,800 kilometers in 1960 and 4,2090 in 1990, is estimated to rise to 7,900 kilometers in 2020 - given a modest average increase in Gross World Product of 1.9% per year. Higher economic growth rates in Asian regions result in an increase in regional per capita traffic volume up to a factor of 5.3 from 1990 levels. Modal splits continue shifting to more flexible and faster modes of transport. At one point, passenger cars can no longer satisfy the increasing demand for speed (i.e. rising mobility within a fixed time budget). In North America it is estimated that the absolute traffic volume of automobiles will gradually decline starting in the 2010s. (author) 13 figs., 6 tabs., 35 refs.

    water delivery and irrigation system efficiencies. These could potentially reduce demands substantially. However, overall demands remained high under our fossil-fuel-only tax policy. In contrast, when all carbon was priced, increases in agricultural water demands were smaller than under the fossil-fuel-only policy and were driven primarily by increased demands for water by non-biomass crops such as rice. Finally we estimate the geospatial pattern of water demands and find that regions such as China, India and other countries in south and east Asia might be expected to experience greatest increases in water demands.

    Pumping water for agricultural irrigation represents a significant share of California’s annual electricity use and peak demand. It also represents a large source of potential flexibility, as farms possess a form of storage in their wetted soil. By carefully modifying their irrigation schedules, growers can participate in demand response without adverse effects on their crops. This report describes the potential for participation in demand response and automated demand response by agricultural irrigators in California, as well as barriers to widespread participation. The report first describes the magnitude, timing, location, purpose, and manner of energy use in California. Typical on-­farm controls are discussed, as well as common impediments to participation in demand response and automated demand response programs. Case studies of demand response programs in California and across the country are reviewed, and their results along with overall California demand estimates are used to estimate statewide demand response potential. Finally, recommendations are made for future research that can enhance the understanding of demand response potential in this industry.

    1988-01-01

    Industrial occupations which are physically strenuous in the traditional sense of the word have decreased in number. They have partly been replaced by "light," repetitive, monotonous work tasks performed in a sitting position. The number of heavy work tasks within the service sector has increased. Specialization has been intensified. The individual's capacity for strenuous work is still of importance to successful work performance. Many studies show that an optional choice of work pace in physically demanding occupational work results in an adaptation of pace or intensity until the worker is utilizing 40-50% of her or his capacity. When the work rate is constrained, the relative strain of the individual varies inversely with the physical work capacity. The frequency of musculoskeletal disorders has concurrently increased with the implementation of industrial mechanization. New, wise, ergonomic moves are needed to stop this development.

  20. The Many Faces of Supplier Induced Demand in Health Care

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available "nHealth economists look towards health care sector as a market whereby there is a distinct demand and supply phenomenon exists. Dearth of regulation of the doctors' practices lead to inappropriate and unjustifiable demand for health care among the patients. In developing and under-developed countries, this adverse practice may push a poor family into a vicious circle of poverty and illness, especially where out of pocket expenditure on health is too high. Unnecessary prescriptions, pro­longed treatments and unjustified user fee grossly deprive the patient's family financially. In developed countries, the flourishing health care technology and sophisticated laboratory diagnostics could incur significant expenditure which is sometimes even not covered under the insurance. State is the custodian of health care in any country; therefore, vigilant regulation of the health care providers may curb the supplier induced demand through strict laws and policies.

    Price, income and health status are likely to affect the demand for healthcare in developing countries, and their quantitative effects are unclear in the literature. Some studies report that prices are not important determinants, while others conclude that prices are important determinants of the demand for healthcare. Knowledge of the extent to which price, income and health status affect the demand for healthcare is crucial for the design of effective health policy in developing countries. To examine the role of monetary and non-monetary price, income, and a variety of individual- and household-specific characteristics on the demand for healthcare in rural India. Utilizing micro data from the 52nd round of India's National Sample Survey, a variable choice set based on geographical location, price, income and the severity of illness was constructed to reflect the underlying true choice-generating process in rural India. Nested multinomial logit models were estimated and simulations with respect to prices and income were conducted to estimate price and income elasticities. Contrary to many earlier studies on the demand for healthcare in developing countries, it was found that prices and income were statistically significant determinants of the choice of healthcare provider by individuals in rural India. Demand for healthcare was found to be price and income inelastic, corroborating the findings from other developing countries. Distance to formal healthcare facilities negatively affected the demand for outpatient healthcare, an effect that was mitigated as access to transportation improved. Age, sex, healthy days, educational status of the household members and the number of children and adults living in the household also affected the choice of healthcare provider in rural India. After controlling for a number of sociodemographic factors, it was found that prices, income and distance are statistically significant determinants of the provider chosen by individuals

    In China, more than 80% electricity comes from coal which dominates the CO2 emissions. Residential electricity demand forecasting plays a significant role in electricity infrastructure planning and energy policy designing, but it is challenging to make an accurate forecast for developing countries. This paper forecasts the provincial residential electricity consumption of China in the 13th Five-Year-Plan (2016-2020) period using panel data. To overcome the limitations of widely used predication models with unreliably prior knowledge on function forms, a robust piecewise linear model in reduced form is utilized to capture the non-deterministic relationship between income and residential electricity consumption. The forecast results suggest that the growth rates of developed provinces will slow down, while the less developed will be still in fast growing. The national residential electricity demand will increase at 6.6% annually during 2016-2020, and populous provinces such as Guangdong will be the main contributors to the increments.

    Full Text Available Modern organizations face the challenge of having to manage an increasing amount of information. The resulting information overload leads more and more to problems in decision making with potentially negative economic consequences. Decision-makers and knowledge intensive workers are especially affected. To address this problem, information demand patterns were proposed which capture organizational knowledge about the information demand of single roles. This work extends the concept of information demand patterns from single roles to teams. Using the knowledge intensive field of project management, the paper shows how to apply the concept of information demand patterns for a whole team. The contributions of this work are (1 the methodical approach to develop information demand patterns for teams, (2 an actual information demand pattern for a steering committee in the context of project management, (3 reflections on the differences between role patterns and team patterns.

  6. A Growing Demand for Monitoring and Evaluation in Africa

    Directory of Open Access Journals (Sweden)

    Stephen Porter

    2013-09-01

    Full Text Available When decision-makers want to use evidence from monitoring and evaluation (M&E systems to assist them in making choices, there is a demand for M&E. When there is great capacity to supply M&E information, but low capacity to demand quality evidence, there is a mismatch between supply and demand. In this context, as Picciotto (2009 observed, ‘monitoring masquerades as evaluation’. This article applies this observation, using six case studies of African M&E systems, by asking: What evidence is there that African governments are developing stronger endogenous demand for evidence generated from M&E systems?The argument presented here is that demand for evidence is increasing, leading to further development of M&E systems, with monitoring being dominant. As part of this dominance there are attempts to align monitoring systems to emerging local demand, whilst donor demands are still important in several countries. There is also evidence of increasing demand through government-led evaluation systems in South Africa, Uganda and Benin. One of the main issues that this article notes is that the M&E systems are not yet conceptualised within a reform effort to introduce a comprehensive results-based orientation to the public services of these countries. Results concepts are not yet consistently applied throughout the M&E systems in the case countries. In addition, the results-based notions that are applied appear to be generating perverse incentives that reinforce upward compliance and contrôle to the detriment of more developmental uses of M&E evidence.

    An understanding of the relationship of economic growth and potential petroleum product demand is needed to forecast the potential for North American oil demand growth as well as knowledge of world supply and price. The bullish expectations for economic growth in the US and Canada auger well for North American refiners and marketeers. The growth in world economic output forecast, however, means a larger oil demand and an increase in OPEC`s pricing power. Such price increases could depress North American oil demand growth.

  9. Demand for International Reserves in Turkey

    Directory of Open Access Journals (Sweden)

    Yimaz Sinem

    2014-06-01

    Full Text Available Having an important place in the international monetary system, international reserves held by central bank usually reflect country’s economic strength in terms of international finance and trade. There are many reasons for holding international reserves by central banks such as financing the deficit in the balance of payment, managing the monetary and exchange rate policies, minimizing the negative effects of external shocks and reducing the cost of borrowing. Continuously changing and diversifying characteristics of these reasons affect the demand for reserves depending to the economic conditions of the country. Over the last ten years, there has been a tremendous increase in international reserves held by Turkish Central Bank. From 2002 to 2012, the reserves of the bank have risen from 20 billion dollars to 96 billion dollars, showing an increase more than four times. This sudden and huge increase in the foreign reserves drove us to determine and investigate the factors which induce the Turkish Central Bank to hold high level of reserves. Thus, the purpose of this study is to estimate and analyze the demand for international reserves held by central banks using the buffer stock model in the case of Turkey. The data used in the study is monthly and cover the period of 1990:03-2012:10. The buffer stock model was econometrically estimated by using the OLS method for three different models. Our findings indicate that the opportunity cost affected reserve demand much stronger than the reserve volatility in Turkish case.

  14. Social obstacles in curbing residential energy demand

    Energy Technology Data Exchange (ETDEWEB)

    Anker-Nilssen, Per [Norwegian School of Management BI, Sandvika (Norway). Centre for Energy and Environment

    2003-07-01

    The continuing growth in residential energy-use does not comply with policy targets for curbing end-user demand. Households are steadily increasing their energy-use, offsetting energy efficiency improvements, to gain time, convenience, comfort and mobility. If sustainable development presupposes lowering demand, it conflicts with present energy-driven changes in life-styles. Environmental degradation due to energy-use gives incentives to raise taxes and duties. The Norwegian experience is that rising income increase households' energy consumption while decreasing its share of total expense. Consequently, higher prices hit low-income households that account for a minor share of total household demand. Since energy represents a purchased input factor to accomplish tasks, the burden is twofold. Energy consumption losses also represent the loss of time and thus money. Additionally, these households have less financial reserves to invest in energy saving. Hence, impact of price hikes (e.g. cold weather) has a regressive social effect. This paper argues that heavy taxation of end-user energy within current practices including tax recycling or deduction, is neither advisable nor politically viable to obtain set targets. Panel data of individual households' electricity use in Oslo suggests that low-income households can not counteract sudden price-hikes but adjust long-term, while the opposite applies to high-income households. In the discussion on environmental policy towards energy-use, the socio-economic effect of measures must be emphasised. New conceptualisations of the world-wide problems in energy and mobility that transforms into agreements on e.g. emission control, can result in added burdens on the poor in industrialised countries rather than the developing countries at large.

    This paper describes the results from the second season of research to develop and evaluate the performance of new Automated Demand Response (Auto-DR) hardware and software technology in large facilities. Demand Response (DR) is a set of activities to reduce or shift electricity use to improve the electric grid reliability and manage electricity costs. Fully-Automated Demand Response does not involve human intervention, but is initiated at a home, building, or facility through receipt of an external communications signal. We refer to this as Auto-DR. The evaluation of the control and communications must be properly configured and pass through a set of test stages: Readiness, Approval, Price Client/Price Server Communication, Internet Gateway/Internet Relay Communication, Control of Equipment, and DR Shed Effectiveness. New commissioning tests are needed for such systems to improve connecting demand responsive building systems to the electric grid demand response systems.

  3. CAUSES AND EFFECTS OF THE GLOBAL DECREASE IN DEMAND

    Directory of Open Access Journals (Sweden)

    Milenko Krajisnik

    2014-12-01

    Full Text Available The current economic crisis has been lasting too long, and particular examples of economic growth and unemployment reduction in some countries have not been the accelerator sufficient for the global recovery. The general level of demand is low, hence so are the investments, although the most powerful economic factors, i.e. the highly developed countries and transnational companies, have the capacities for new investment cycles. This work analyses the causes and effects of decrease in demand, as well as the options available for removal of those causes and revitalization of the effects. One of the main causes of decrease in demand in a long run is the asymmetrical distribution of income which has led to a reduction in purchasing power of a large number of consumers, high debt level and change in demand structure. An additional problem, which can be regarded also as a cause of decline in demand in the short run, is the austerity policy which is being implemented both where necessary and conditioned and where voluntary albeit not necessary. In order to overcome the problem, it is necessary to increase and maintain demand, first initially and then permanently, which is where the state plays an important role.

    ENGLISH ABSTRACT: It is commonly assumed that intermittent demand appears randomly, with many periods without demand; but that when it does appear, it tends to be higher than unit size. Basic and well-known forecasting techniques and stock policies perform very poorly with intermittent demand, making new approaches necessary. To select the appropriate inventory management policy, it is important to understand the demand pattern for the items, especially when demand is intermittent. The use of a forecasting method designed for an intermittent demand pattern, such as Croston’s method, is required instead of a simpler and more common approach such as exponential smoothing. The starting point is to establish taxonomic rules to select efficiently the most appropriate forecasting and stock control policy to cope with thousands of items found in real environments. This paper contributes to the state of the art in: (i categorisation of the demand pattern; (ii methods to forecast intermittent demand; and (iii stock control methods for items with intermittent demand patterns. The paper first presents a structured literature review to introduce managers to the theoretical research about how to deal with intermittent demand items in both forecasting and stock control methods, and then it points out some research gaps for future development for the three topics.

    Changes in internet search trends can provide healthcare professionals detailed information on prevalence of disease and symptoms. Chronic venous disease, more commonly known as varicose veins, is a common symptomatic disease among the adult population. This study aims to measure the change in global search demand for varicose vein information using Google over the past 8 years. The Google Trends instrument was used to measure the change in demand for the use of the local name for varicose veins in several countries across the world between January 2006 and December 2012. The measurements were normalised onto a scale relative to the largest volume of search requests received during a designated time and geographical location. Comparison of national levels of private healthcare and healthcare spending per capita to search demand was also undertaken using Organisation for Economic Co-operation and development economic measurements. Global interest has increased significantly, with linear regression demonstrating a 3.72% year-on-year increase in demand over the 8-year time period (r(2 )= 0.385, p demand significantly increased in the northern hemisphere (p demand compared to cooler winter months (demand (r(2 )= 0.120 p = 0.306). Healthcare spending per capita did not relate to search demand (r(2 )= 0.450 p = 0.077). There is increasing demand for information about varicose veins on the internet, especially during the warmer months of the year. Online search demand does not appear to be related to healthcare spending. © The Author(s) 2014.

    We provide various estimates of temperature effect for accommodating seasonality in energy demand, particularly natural gas demand. We exploit temperature response and monthly temperature distribution to estimate the temperature effect on natural gas demand. Both local and global smoothed temperature responses are estimated from empirical relationship between hourly temperature and hourly energy consumption data during the sample period (1990 - 1996). Monthly temperature distribution estimates are obtained by kernel density estimation from temperature dispersion within a month. We integrate temperature response and monthly temperature density over all the temperatures in the sample period to estimate temperature effect on energy demand. Then, estimates of temperature effect are compared between global and local smoothing methods. (author). 15 refs., 14 figs., 2 tabs.

    A lot of people lost their lives in the tremendous earthquake in Tohoku region on March 11. A large capacity of electric power plants in TEPCO area was also damaged and large scale power shortage in this summer is predicted. In this situation, electricity customers are making great effort to save electricity to avoid planned outage. Customers take actions not only by their selves but also by some customers' cooperative movements. All actions taken actually are based on responses to request form the government or voluntary decision. On the other hand, demand response based on a financial stimulus is not observed as an actual behavior. Saving electricity by this demand response only discussed in the newspapers. In this commentary, the events regarding electricity-saving measure after this disaster are described and the discussions on demand response, especially a raise in power rate, are put into shapes in the context of this electricity supply-demand gap.

    Long-term food demand scenarios are an important tool for studying global food security and for analysing the environmental impacts of agriculture. We provide a simple and transparent method to create scenarios for future plant-based and animal-based calorie demand, using time-dependent regression models between calorie demand and income. The scenarios can be customized to a specific storyline by using different input data for gross domestic product (GDP) and population projections and by assuming different functional forms of the regressions. Our results confirm that total calorie demand increases with income, but we also found a non-income related positive time-trend. The share of animal-based calories is estimated to rise strongly with income for low-income groups. For high income groups, two ambiguous relations between income and the share of animal-based products are consistent with historical data: First, a positive relation with a strong negative time-trend and second a negative relation with a slight negative time-trend. The fits of our regressions are highly significant and our results compare well to other food demand estimates. The method is exemplarily used to construct four food demand scenarios until the year 2100 based on the storylines of the IPCC Special Report on Emissions Scenarios (SRES). We find in all scenarios a strong increase of global food demand until 2050 with an increasing share of animal-based products, especially in developing countries. PMID:26536124

  15. An econometrics method to estimate demand of sugar

    Full Text Available Sugar is one of the strategic goods in the basket of households in each country and it plays an important role in supplying the required energy. On the other hand, it is one of the goods, which Iranian government is about to change its subsidy strategies. To design useful sugar subsidy strategies, it is necessary to know sugar position in the basket of households and be familiar with households' sugar demand or consumption behavior. This research estimates sugar demand for Iranian households by using time series of 1984-2008, which is taken from central bank of Iran. In this paper, first independent and dependent variables of household sugar demand model are chosen based on the literature review and theory of demand. Then, sugar demand is estimated by OLS technique and linear regression. The preliminary statistical observations such as Durbin-Watson, F statistic and R2 indicate that the regression is admissible. The results seem plausible and consistent with theory and show that sugar demand in Iranian households is associated with household expenditure, relative sugar price, family size and indicate that demand of sugar is affected during the war time. The results also show the income elasticity is 0.8 and price elasticity is -0.2 which means sugar is essential good for Iranian households and is inelastic to price.

    Venezuela's current economic and demographic situation is described. Venezuela is a major oil country, and the oil industry accounts for 90% of the country's foreign exchange, 70% of the government's revenues, and 15% of the gross domestic product. The economy experienced a sudden and high rate of economic growth in the mid-1970s as a result of high oil prices; however, in recent years, declining oil prices have had a negative effect on the economy. The country is now faced with a serious trade deficit, and the government recently imposed restrictions on imports. Imports in recently years had increased markedly. The emphasis on the oil industry weakened the agricultural sector and, as a result, food imports increased. In addition, the rapid economic growth experienced during the 1970s greatly increased the demand for imported consumer goods. Venezuela has the 4th highest foreign debt in the world (US$35 billion). Despite these problems Venezuela has a relatively high per capita income (US$4,140) and living standard, compared to other countries in the region. Venezuela's total population is 14.6 million, and the population is unevenly distributed. 86% of the population lives in cities of 2500 or more. 37.4% of the population and 70% of the industry is concentrated in the Federal District which contains Caracas, and in the surrounding states of Aragua, Miranda, and Carabobo. This area constitutes only 2.36% of the country's territory. Most of the oil fields are located in the state of Zulia which also contains the country's 2nd largest city (Maracaibo). The country's coastal area contains most of the agricultural lands, and the prairies just south of the coastal mountain ranges are devoted primarily to cattle raising. The remaining 58.2% of the country's territory is essentially jungle and contains only 6.9% of the country's population. The annual population growth rate is 3.11%. Although the rate declined in recent years it is higher than in most of the other

    While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers' education was only statistically significant in determining abortion demand but not post-abortion care demand. The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this in the absence of proper post

    Full Text Available AbstractGasoline and diesel are the main sources of fuel required for modern life and transportation, and the adjustment of gasoline and diesel prices has become a major public issue. The drastic fluctuations in recent international oil prices have affected retail gasoline and diesel prices also in the Western Balkan countries and prompted public opinion to question the pricing behaviors of oil companies. Kosovo, in the period of 17 years, has gone from a post-conflict  environment  into a state which is considered to be under transition. It has passed the reconstruction period by orienting itself toward the economic development  and European Integrations.  Price and income elasticities of gasoline demand show whether the price policy, pursued by the Kosovo government, can decrease the high gasoline consumption sufficiently or not. The high deficit of the current account of balance of payments is also a concern for the Kosovo’s economy; which is estimated up to 17.3% of the GDP after the foreign intervention.   The deficit of current account is being considered is related to the energy dependency. Therefore, in order to overcome such problems, control over the gasoline demand is needed to control the deficit of current accounts. Keywords:  oil price, economic development, imports, trade deficit.

  6. THE PRICE OF HIGHER EDUCATION AND INDIVIDUAL DEMAND

    Directory of Open Access Journals (Sweden)

    Filiz Golpek

    2012-01-01

    Full Text Available The rise in the living standards in most of the world, the rise in population and schooling rates have increased the demand for higher education. The attribution of semi public property becomes determinant to decide whom will provide the supply and the production in semi public properties is realized by means of a supply and demand mechanism. The supply of higher education is mostly secured in accordance with the public demand as well as the resources available.  In addition, the fact that higher education services have produced significant benefits has led to over demand. This situation relates to a simple economic rule that a commodity or service which costs almost nothing or little will increase until the mariginal benefit of its demand equals to 0 or almost 0. However, the educational supply and demand is difficult to identify in accordance to the supply and demand and balance of price as observed in the economic theory. The high profits that would be attracted in the future are significant factors influencing individual’s decisions for investment. The decision for investment depends on the possible return in the future, the cost of investment, and the current interest rates. Higher education with investment purposes is influenced by these three factors and higher education is demanded more and more by individuals on the expectation that they will gain high profits In theory, it is accepted that the basic factors identifying the demand for higher education are in harmony with empirical research results in several countries including Turkey.

Proprietors of eleven economic models of the world oil market used their respective models to simulate a dozen scenarios using standardized assumptions. From its inception, the study was not designed to focus on the short-run impacts of disruptions on oil markets. Nor did the working group attempt to provide a forecast or just a single view of the likely future path for oil prices. The model results guided the group's thinking about many important longer-run market relationships and helped to identify differences of opinion about future oil supplies, demands, and dependence.

    Instances of transportation models are abundant and detailed "how to" instruction is available in the form of transportation software help documentation. The purpose of this paper is to look at the fundamental inputs required to build a transportation model by developing an example passenger travel demand model. The example model reduces the scale to a manageable size for the purpose of illustrating the data collection and analysis required before the first step of the model begins. This aspect of the model development would not reasonably be discussed in software help documentation (it is assumed the model developer comes prepared). Recommendations are derived from the example passenger travel demand model to suggest future work regarding the data collection and analysis required for a freight travel demand model.

    During periods of peak electrical demand on the energy grid or when there is a shortage of supply, the stability of the grid may be compromised or the cost of supplying electricity may rise dramatically, respectively. Demand response programs are designed to mitigate the severity of these problems and improve reliability by reducing the demand on the grid during such critical times. In 2010, the Demand Response Research Center convened a group of industry experts to suggest potential industries that would be good demand response program candidates for further review. The dairy industry was suggested due to the perception that the industry had suitable flexibility and automatic controls in place. The purpose of this report is to provide an initial description of the industry with regard to demand response potential, specifically automated demand response. This report qualitatively describes the potential for participation in demand response and automated demand response by dairy processing facilities in California, as well as barriers to widespread participation. The report first describes the magnitude, timing, location, purpose, and manner of energy use. Typical process equipment and controls are discussed, as well as common impediments to participation in demand response and automated demand response programs. Two case studies of demand response at dairy facilities in California and across the country are reviewed. Finally, recommendations are made for future research that can enhance the understanding of demand response potential in this industry.

The model is used to evaluate two tests that have been used to test for the existence of supplier-induced demand. The analysis suggests that the two tests, which compare the medical utilization of informed and uninformed consumers, are not valid.

    This paper describes the development of end-use electricity projections and load curves that were developed for the Renewable Electricity (RE) Futures Study (hereafter RE Futures), which explored the prospect of higher percentages (30% - 90%) of total electricity generation that could be supplied by renewable sources in the United States. As input to RE Futures, two projections of electricity demand were produced representing reasonable upper and lower bounds of electricity demand out to 2050. The electric sector models used in RE Futures required underlying load profiles, so RE Futures also produced load profile data in two formats: 8760 hourly data for the year 2050 for the GridView model, and in 2-year increments for 17 time slices as input to the Regional Energy Deployment System (ReEDS) model. The process for developing demand projections and load profiles involved three steps: discussion regarding the scenario approach and general assumptions, literature reviews to determine readily available data, and development of the demand curves and load profiles.

  9. Demand as frequency controlled reserve

    Energy Technology Data Exchange (ETDEWEB)

    Xu, Z.; Togeby, M.; OEstergaard, J.

    2008-09-15

    Using demand as frequency controlled reserve (DFR) is an emerging technology which allow demand to participate actively in maintaining the system operation without reducing the energy service delivered to the customer and without need of user interaction. The basic premise is that traditional frequency controlled reserves from power plants and interconnections with neighbouring systems can be costly, slow and not fulfil the need for future power grids with a high share of wind power and fewer central power plants, and an intention to perform flexible operation such as is landing. Electricity demands, on the other hand, have advantages as frequency reserve including fast activation speed, smooth linear activation, low expected costs, and well-dispersed in the distribution grid. The main challenge of DFR is new methods for monitoring the available capacity. This project has investigated the technology of using electricity demands for providing frequency reserve to power systems. Within the project the potential and economy of DFR compatible loads in Denmark has been investigated, control logic has been designed, power system impact has been investigated, potential business models has been evaluated and an implementation strategy has been suggested. The tasks and goals of the project have been successfully accomplished based on which the conclusion and future recommendation are made. This project has developed the DFR technology that enables electricity demands to autonomously disconnect or reconnect to the grid in response to system frequency variations. The developed DFR technology is proved to be a promising technology from several perspectives. Technically, using DFR is feasible to provide reserves and enhance power system frequency control, while fulfilling technical requirements such as linear activation (or reconnection) according to frequency (or time). Environmentally, the DFR technology is pollution free in contrast to traditional reserves from generation

  10. Structural Breaks, Parameter Stability and Energy Demand Modeling in Nigeria

    Directory of Open Access Journals (Sweden)

    Olusegun A. Omisakin

    2012-08-01

    Full Text Available This paper extends previous studies in modeling and estimating energy demand functions for both gasoline and kerosene petroleum products for Nigeria from 1977 to 2008. In contrast to earlier studies on Nigeria and other developing countries, this study specifically tests for the possibility of structural breaks/regime shifts and parameter instability in the energy demand functions using more recent and robust techniques. In addition, the study considers an alternative model specification which primarily captures the price-income interaction effects on both gasoline and kerosene demand functions. While the conventional residual-based cointegration tests employed fail to identify any meaningful long run relationship in both functions, the Gregory-Hansen structural break cointegration approach confirms the cointegration relationships despite the breakpoints. Both functions are also found to be stable under the period studied.The elasticity estimates also follow the a priori expectation being inelastic both in the long- and short run for the two functions.

  11. Household water demand and welfare loss for future Europe

    Science.gov (United States)

    Bernhard, Jeroen; Reynaud, Arnaud; Lanzanova, Denis; de Roo, Ad

    2015-04-01

    Matching the availability of water to its demand in Europe is a major challenge for the future due to expected economic and demographic developments and climate change. This means there is a growing need to estimate future water demand and to optimize the water allocation to all end users to counteract welfare loss. At the European scale it is currently not possible to assess the impact of social and economic changes on future water demand or to prioritize water allocation amongst different sectors based on economic damage without extensive use of assumptions and generalizations. Indeed, our review of existing regional optimization models for Europe reveals that the social-economic component of the water use system needs to be improved by complementing them with detailed water use estimates and cost/benefit functions in order to determine the optimal situation. Our study contributes to closing this knowledge gap for the European household sector by quantifying future water demand and the effect of water pricing, as well as providing a method for the calculation of monetary damage due to unmet demand at the highest spatial resolution possible. We used a water demand function approach in which household water consumption depends upon some exogenous drivers including water price, household income, population and household characteristics and climate conditions. For each European country, the annual water consumption per capita was calculated at regional level (NUTS3) and subsequently disaggregated to five kilometer grid level based on a population density map. In order to produce estimates of water demand, the evolution of the explanatory variables of the water demand functions and population density map were simulated until 2050 based on related variables such as GDP and demographic projections. The results of this study will be integrated into the JRC hydro-economic modelling framework for an assessment of the Water-Agriculture-Energy-Ecosystems Nexus.

    2015-01-01

    Administrative structure of drug demand reduction and the way in which involved organizations interact with each other has been neglected by researchers, policy makers, and administrators at the national level and even in international institutions in this field. Studying such structures in different countries can reveal their attributes and features. In this study, key experts from the addictive behavior department of St George's University of London and a group of Iranian specialists in the field of drug demand reduction first wrote on a sheet the name of organizations that are in charge of drug demand reduction. Then, via teamwork, they drew the connections between the organizations and compared the two charts to assess the relations between the member organizations. In total, 17 features of efficient structure were obtained as follow: multi-institutional nature, collaborative inter-institutional activities, clear and relevant inter-institutional and intra-institutional job description, the ability to share the experiences, virtual institutions activity, community-based associations activity, mutual relationships, the existence of feedback sys-tems, evaluation, changeability, the ability to collect data rapidly, being rooted in community, flexibility at the local and regional levels, connection with research centers, updated policymaking, empowering the local level, and seeking the maximum benefit and the minimum resources. Recognizing the characteristics of substance related organizations in various countries could help policy makers to improve drug demand reduction structures and to manage the wide-spread use of psychoactive substances more effectively.

  13. Demand chain management - The evolution

    Directory of Open Access Journals (Sweden)

    D Ericsson

    2011-06-01

    Full Text Available The concepts of Supply Chain Management (SCM and Demand Chain Management (DCM are among the new and debated topics concerning logistics in the literature. The question considered in this paper is: “Are these concepts needed or will they just add to the confusion?” Lasting business concepts have always evolved in close interaction between business and academia. Different approaches start out in business and they are then, more or less si- multaneously, aligned, integrated, systemised and structured in academia. In this way a terminology (or language is provided that helps in further diffusion of the concepts. There is a lack of consensus on the definition of the concept of SCM. This may be one of the major reasons for the difficulty in advancing the science and measuring the results of implementation in business. Relationships in SCM span from rather loose coalitions to highly structured virtual network integrations. DCM is a highly organised chain in which the key is mutual interdependence and partnership. The purpose is to create a distinctive competence for the chain as a whole that helps to identify and satisfy customer needs and wishes. The classical research concerning vertical marketing systems is very helpful in systemising the rather unstructured discussions in current SCM research. The trend lies in increasing competition between channels rather than between companies, which in turn leads to the creation of channels with a high degree of partnership and mutual interdependence between members. These types of channels are known as organised vertical marketing systems in the classic marketing channel research. The behaviour in these types of channels, as well as the formal and informal structures, roles in the network, power and dependence relations, etc. are well covered topics in the literature. The concept of vertical marketing systems lies behind the definition of demand chains and demand chain management proposed in this paper. A

    Energy Technology Data Exchange (ETDEWEB)

    Trocki, L.; Booth, S.R.; Umana Q, A.

    1987-06-01

    This study describes the energy resources and the changes that have taken place in energy supply and demand in five Central American countries between 1970 and 1984. Economic changes are also reviewed because they influence and are affected by changes in the energy sector. The work was performed under the auspices of the US Agency for International Development. The Central American countries of Costa Rica, El Salvador, Guatemala, Honduras, and Panama are highly dependent on fuel wood as a source of energy, particularly in the residential sector. They also rely upon imported oil products to supply a growing modern sector. Most countries have significant hydroelectric and geothermal resources, and most countries produce a large portion of their electricity from hydroelectric projects. Demand for electricity has grown rapidly. Relative shares of primary versus secondary energy in the five countries vary significantly and strongly correlate with average per capita income. Consumption of secondary energy has declined during the recent economic recession suffered by the region.

  17. Contribution of livestock to food production in developing countries

    Directory of Open Access Journals (Sweden)

    H. FITZHUGH

    2008-12-01

    Full Text Available On a global basis, livestock products - meat, milk, eggs and fibre - account for 40% of the value of total marketed agricultural product. Animal products provide essential amino acids, vitamins and minerals to help ensure nutritionally balanced diets. In developing countries, livestock traction and manure also contribute to food production through improved cultivation and soil fertility which increase crop yields. On average, the proportional contribution of livestock product to dietary calories and protein in developed countries is double that for developing countries. Demand for livestock products is fuelled by the population increase, income growth and urbanisation in developing countries. Therefore, over the past decade, consumption of livestock product has sharply increased in developing countries, while slightly decreasing in developed countries where consumption is already relatively high on average. Increased demand in developing countries increases income for producers, but also stresses the environment through pollution, soil erosion, overgrazing and deforestation. Research involving global partnerships of scientists and institutes can help ensure that the increased demands for livestock product in developing countries will be met in economically feasible and environmentally sustainable ways.;

    Full Text Available The paper is devoted to energy demand forecasting in Uzbekistan. Studies show that in spite of the abundant reserves of hydrocarbons, low energy efficiency can have an adverse impact on energy security in Uzbekistan in the future. Oil and gas are the main primary energy source and they ensure energy security of Uzbekistan. Energy demand forecasting is essential in order to develop an effective energy policy. Such forecast can be useful to plan oil and gas production volumes, to identify priorities for the industrial modernization and to create favorable conditions for sustainable economic development in the future.

  6. Energy demand and population change.

    Science.gov (United States)

    Allen, E L; Edmonds, J A

    1981-09-01

    During the post World War 2 years energy consumption has grown 136% while population grew about 51%; per capita consumption of energy expanded, therefore, about 60%. For a given population size, demographic changes mean an increase in energy needs; for instance the larger the group of retirement age people, the smaller their energy needs than are those for a younger group. Estimates indicate that by the year 2000 the energy impact will be toward higher per capita consumption with 60% of the population in the 19-61 age group of workers. Rising female labor force participation will increase the working group even more; it has also been found that income and energy grow at a proportional rate. The authors predict that gasoline consumption within the US will continue to rise with availability considering the larger number of female drivers and higher per capita incomes. The flow of illegal aliens (750,000/year) will have a major impact on income and will use greater amounts of energy than can be expected. A demographic change which will lower energy demands will be the slowdown of the rate of household formation caused by the falling number of young adults. The response of energy demand to price changes is small and slow but incomes play a larger role as does the number of personal automobiles and social changes affecting household formation. Households, commercial space, transportation, and industry are part of every demand analysis and population projections play a major role in determining these factors.

  7. THE METABOLIC DEMANDS OF KAYAKING: A REVIEW

    Directory of Open Access Journals (Sweden)

    Jacob S. Michael

    2008-03-01

    Full Text Available Flat-water kayaking is one of the best-known competitive canoeing disciplines in Australia and across the European countries. From a stationary start, paddlers are required to paddle their kayaks with maximal effort along the length of the competing distance. The ultimate criterion of kayak performance is the time taken to paddle a designated competition distance. In flat-water racing, events are contested over 500 and 1000 metres. To approximate the ultimate criterion over these distances, the velocity of the kayak should be measured. Furthermore, other factors that affect performance, such as force, power, technique and aerobic fitness, would all provide a valuable insight to the success of the kayak paddler. Specific research performed examining the physiological demands on kayak paddlers demonstrate high levels of both aerobic power and anaerobic capacity. It is the purpose if this review to present the published physiological data relating to men's and women's kayaking. With a number of recent publications, a need for an updated review is necessary. The present review summarises recent data on anthropometrics, physiological characteristics of successful and unsuccessful kayak athletes and methods of physiological testing. Due to the fact that more data have been reported for male competitors than for their female counterparts, the demands of kayaking on male athletes will be the main focus for this review. The review also suggests areas for future research into flatwater kayaking performance. Understanding the physiological requirements of kayaking can assist coaches and athletes in a number of ways. During competition or training, such information is helpful in the selection of appropriate protocols and metabolic indices to monitor an athlete's performance improvements and assess an athlete's suitability for a particular race distance. Furthermore, it may aid the coach in the development of more specific training programs for their

During competition or training, such information is helpful in the selection of appropriate protocols and metabolic indices to monitor an athlete's performance improvements and assess an athlete's suitability for a particular race distance. Furthermore, it may aid the coach in the development of more specific training programs for their athletes. Key points

  10. THE PERCEPTION OF NEIGHBOUR COUNTRIES IN BULGARIA

    Full Text Available The image of the country can be influential in various buying decisions, especially in cases where there is a strong competition among market players and if price is not the factor with the utmost importance. In a psychosemantic experiment we study the demand patterns for imported goods in Bulgaria. We aim to assess how Bulgarian citizens build their image of other countries, especially the neighbour ones. We find that “market dimension” and “power dimension” are the major factors in the perceptions. We find also that perceptions of Bulgarian respondents give a more important role in Bulgarian economy to globally more important economies, despite the vicinity of neighbour countries.

  11. Modelling seasonal farm labour demand: What can we learn from rural Kakamega district, western Kenya?

    Directory of Open Access Journals (Sweden)

    Vincent Canwat

    2012-09-01

    Full Text Available Seasonality of agricultural activities causes fluctuation in the quantity of labour consumed by these activities, and yet many rural labour studies in developing countries still treat labour demand in agriculture as if it is the same across different farm operations. To unearth the amount of information hidden by this aggregated analysis, labour demand for specific farm operations was estimated based on data collected from Kakamega District. This analysis shows that increasing household size increases labour demand for planting, weeding and harvesting. Increasing the share of elderly household members has a negligible effect on labour demand for farm activities except for land preparation, with which it is positively related. Participation of primary school-going children in farm activities is the highest in planting and harvesting. Participation in off-farm employment seems to increase labour demand only during peak seasons. The area planted appears to have an insignificant effect on labour demand for land preparation. Planting sugar cane appears to reduce labour demand for weeding and primary processing, but planting tea increases labour demand for planting. Mechanising land preparation only reduces labour demand for land preparation, but it seems to be offset by other labour-intensive farm operations. The distance from water source is positively related to labour demand for land preparation, but the distance to the market is negatively related to labour demand for weeding and harvesting. These observations point to the need for supporting and investing in technological and organisational innovations in agriculture.

    Wigaeus, E; Kilbom, A

    1980-01-01

    This investigation was undertaken to evaluate the aerobic demands during one of the most popular and demanding Swedish folk dances the "hambo". Six men and six women, ranging in age from 22 to 32, participated. Their physical work capacity was investigated on a bicycle ergometer and a treadmill, using two to three submaximal and one maximal loads. All subjects were moderately well-trained and their average maximal oxygen uptake on the treadmill were 2.5 and 3.7 l/min (42.8 and 53.2 ml/kg . min-1) for women and men, respectively. When dancing the "hambo" the heart rate was telemetered, and the Douglas bag technique was used for measurements of pulmonary ventilation and oxygen uptake. The physical demand during "hambo" dancing was high in all subjects. Oxygen uptake was 38.5 and 37.3 ml/kg . min-1 and heart rate 179 and 172 in women and men, respectively. Women used 90% and men 70% of their maximal aerobic power obtained on the treadmill. The pulmonary ventilation and respiratory quotient of the female subjects were lower when dancing as compared to running, possibly because of voluntary restriction of the movements of the thoracic cage. Some popular Scandinavian folk dances are performed at a speed and with an activity pattern resembling the "hambo", while others are performed at a slower pace. The exercise intensity used in "hambo" is more than sufficient to induce training effects in the average individual provided that the dancing is performed at the frequency and for length of time usually recommended for physical training. For older or less fit people dances with a slow pace can be used for training purposes.

    Glomb, Theresa M; Kammeyer-Mueller, John D; Rotundo, Maria

    2004-08-01

    The concept of emotional labor demands and their effects on workers has received considerable attention in recent years, with most studies concentrating on stress, burnout, satisfaction, or other affective outcomes. This study extends the literature by examining the relationship between emotional labor demands and wages at the occupational level. Theories describing the expected effects of job demands and working conditions on wages are described. Results suggest that higher levels of emotional labor demands are associated with lower wage rates for jobs low in cognitive demands and with higher wage rates for jobs high in cognitive demands. Implications of these findings are discussed. (c) 2004 APA

  19. Demand Response Valuation Frameworks Paper

    Energy Technology Data Exchange (ETDEWEB)

    Heffner, Grayson

    2009-02-01

    While there is general agreement that demand response (DR) is a valued component in a utility resource plan, there is a lack of consensus regarding how to value DR. Establishing the value of DR is a prerequisite to determining how much and what types of DR should be implemented, to which customers DR should be targeted, and a key determinant that drives the development of economically viable DR consumer technology. Most approaches for quantifying the value of DR focus on changes in utility system revenue requirements based on resource plans with and without DR. This ''utility centric'' approach does not assign any value to DR impacts that lower energy and capacity prices, improve reliability, lower system and network operating costs, produce better air quality, and provide improved customer choice and control. Proper valuation of these benefits requires a different basis for monetization. The review concludes that no single methodology today adequately captures the wide range of benefits and value potentially attributed to DR. To provide a more comprehensive valuation approach, current methods such as the Standard Practice Method (SPM) will most likely have to be supplemented with one or more alternative benefit-valuation approaches. This report provides an updated perspective on the DR valuation framework. It includes an introduction and four chapters that address the key elements of demand response valuation, a comprehensive literature review, and specific research recommendations.

  20. Demand Side Bidding. Final Report

    2003-12-31

    This document sets forth the final report for a financial assistance award for the National Association of Regulatory Utility Commissioners (NARUC) to enhance coordination between the building operators and power system operators in terms of demand-side responses to Location Based Marginal Pricing (LBMP). Potential benefits of this project include improved power system reliability, enhanced environmental quality, mitigation of high locational prices within congested areas, and the reduction of market barriers for demand-side market participants. NARUC, led by its Committee on Energy Resources and the Environment (ERE), actively works to promote the development and use of energy efficiency and clean distributive energy policies within the framework of a dynamic regulatory environment. Electric industry restructuring, energy shortages in California, and energy market transformation intensifies the need for reliable information and strategies regarding electric reliability policy and practice. NARUC promotes clean distributive generation and increased energy efficiency in the context of the energy sector restructuring process. NARUC, through ERE's Subcommittee on Energy Efficiency, strives to improve energy efficiency by creating working markets. Market transformation seeks opportunities where small amounts of investment can create sustainable markets for more efficient products, services, and design practices.

  1. Positional demands of professional rugby.

    Lindsay, Angus; Draper, Nick; Lewis, John; Gieseg, Steven P; Gill, Nicholas

    2015-01-01

    Rugby union is a physically intense intermittent sport coupled with high force collisions. Each position within a team has specific requirements which are typically based on speed, size and skill. The aim of this study was to investigate the contemporary demands of each position and whether they can explain changes in psychophysiological stress. Urine and saliva samples were collected before and after five selected Super 15 rugby games from 37 players. Total neopterin (NP), cortisol and immunoglobulin A were analysed by SCX-high performance liquid chromatography and enzyme linked immunosorbent assay. Global positioning system software provided distance data, while live video analysis provided impact data. All contemporary demands were analysed as events per minute of game time. Forwards were involved in more total impacts, tackles and rucks compared to backs (p cortisol and sIgA. The results indicate distance covered and number of impacts per minute of game time is position-dependent whereas changes in psychophysiological stress are independent. This information can be used to adapt training and recovery interventions to better prepare each position based on the physical requirements of the game.

  2. Budget, fiscal and monetary policy in Poland and demand for transport – forwarding – logistics industry services

    Directory of Open Access Journals (Sweden)

    Ryszard Rolbiecki

    2013-06-01

    Full Text Available Macroeconomic policy of a country does not always have an effect on the demand for transport. The lack of a clear relation between the nature of macroeconomic policy and changes in demand for transport services is a consequence of the overall complexity of the economic system. It can also be a result of the lack of consistency between budget and monetary policy. Macroeconomic policy as a tool to control global demand only indirectly affects the changes in demand for transport. Transport activity is in fact determined by changes in the real economy, which directly influence the increase or decrease in demand for transport services.

  3. Skewness preference across countries

    Directory of Open Access Journals (Sweden)

    Adam Zaremba

    2015-07-01

    Full Text Available Prospect theory implies that assets with positively skewed returns should be traded at premium to assets with negative skewness. We hypothesize that in the integrated financial markets this concept should also hold for the entire country equity portfolios. This article examines the linkages between the country-level expected returns and past skewness. We evidence a robust negative relationship between skewness and future returns. The phenomenon is most significant within large, liquid, developed, and open stock markets. Additional sorts on skewness can improve performance of both cross-country value and momentum strategies. The study is based on the sorting and cross-sectional tests conducted within a sample of 78 country equity markets for years 1999-2014.

    Full Text Available Scientific cartography has the task to develop and research new methods of cartographic visualization. General demands are set upon modern cartographic visualization, which encompasses digital cartography and computer graphics: legibility, clearness, accuracy, plainness and aesthetics. In this paper, it is explained in detail what demands should be met in order to satisfy the general demands set. In order to satisfy the demand of legibility, one should respect conditions of minimal sizes, appropriate graphical density and better differentiation of known features. Demand of clearness needs to be met by fulfilling conditions of simplicity, contrasting quality and layer arrangement of cartographic representation. Accuracy, as the demand on cartographic visualization, can be divided into positioning accuracy and accuracy signs. For fulfilling the demand of plainness, the conditions of symbolism, traditionalism and hierarchic organization should be met. Demand of aesthetics will be met if the conditions of beauty and harmony are fulfilled.

    The Association of South East Asian Nations or ASEAN is a regional association of seven countries, namely Indonesia, Malaysia, Philippines, Singapore, Thailand, Brunei and Vietnam, located at the south eastern part of the Asian continent. Together with the East Asian States of Japan, China, Korea and Taiwan, this part of the world is experiencing rapid economic growth, especially in the last decade. Rapid industrialization has resulted in an increased demand for energy in the manufacturing and transport sectors, and also for infrastructure development. This has led to a significant increase in gaseous emissions and a corresponding increase in atmospheric acidity. Acid deposition study in the ASEAN countries began in the mid-70s when Malaysia first started her acid rain monitoring network in 1976. This was followed closely by Singapore and the other ASEAN countries in the 80s. By now all ASEAN countries have their own acid rain monitoring networks with a number of these countries extending the monitoring to dry deposition as well.

    2010-03-01

    Full Text Available Developing countries were hit hard by the financial and economic crisis, although the impact was somewhat delayed. Every country had different challenges to master. The closer the developing countries are interconnected with the world economy, the crasser the effects. And the incipient recovery that is becoming noticeable is, for the time being, restricted to only a few countries and regions.The crisis was transmitted primarily by trade and financial flows forcing millions back into poverty. Attainment of the Millennium Development Goals is seriously jeopardised in many countries. Many developing countries did not and do not have the resources to stimulate the economy and protect their socially disadvantaged populations to the same extent as the industrialised countries. However, many countries have made considerable efforts to mitigate the effects. Developing countries have also increased their cooperation with one another and are urgently demanding a greater voice in global economic affairs.The industrialised countries are for the most part more concerned with their own problems. Their readiness to provide more extensive aid is limited. They are under pressure from the international institutions to relax their previous dominance in favour of the increasingly strong emerging countries. A shift in power and influence that was already noticeable before the financial crisis is deepening.

    2012-11-01

    As David Payne famously said, 'we never have a photonic material that we want...'. This has changed with the proliferation of nanotechnology. Metamaterials—artificial media structured on a sub-wavelength scale—offer a radical paradigm for the engineering of optical properties. Some remarkable advances have been possible with metamaterials. These include, for instance, negative-index media that refract light in the opposite direction from that of conventional materials, chiral materials that rotate the polarization state of light hundreds of thousands of times more strongly than natural optical crystals, and structured thin films with remarkably strong dispersion that can slow light in much the same way as resonant atomic systems with electromagnetically induced transparency. The research agenda is now shifting towards achieving tunable and switchable functionalities with metamaterials [1] where the goal is, paraphrasing Dave Payne, 'to have on demand the photonic material that we want'. The papers in this Journal of Optics special issue explore and review the different approaches to both switching and tuning of metamaterial properties through exploiting effects such as phase conjugation, intense photo-excitation and photoconductivity, the use of electro-optical effects in conductive oxides, the exploitation global quantum coherency and resonantly coupled classical resonator and quantum structures, hybridization with gain media and the manipulation with shapes and constitution of the complex metamolecules and metamaterial reliefs by design, or using MEMS actuation.

    Demand response is the largest underutilized reliability resource in North America. Historic demand response programs have focused on reducing overall electricity consumption (increasing efficiency) and shaving peaks but have not typically been used for immediate reliability response. Many of these programs have been successful but demand response remains a limited resource. The Federal Energy Regulatory Commission (FERC) report, 'Assessment of Demand Response and Advanced Metering' (FERC 2006) found that only five percent of customers are on some form of demand response program. Collectively they represent an estimated 37,000 MW of response potential. These programs reduce overall energy consumption, lower green house gas emissions by allowing fossil fuel generators to operate at increased efficiency and reduce stress on the power system during periods of peak loading. As the country continues to restructure energy markets with sophisticated marginal cost models that attempt to minimize total energy costs, the ability of demand response to create meaningful shifts in the supply and demand equations is critical to creating a sustainable and balanced economic response to energy issues. Restructured energy market prices are set by the cost of the next incremental unit of energy, so that as additional generation is brought into the market, the cost for the entire market increases. The benefit of demand response is that it reduces overall demand and shifts the entire market to a lower pricing level. This can be very effective in mitigating price volatility or scarcity pricing as the power system responds to changing demand schedules, loss of large generators, or loss of transmission. As a global producer of alumina, primary aluminum, and fabricated aluminum products, Alcoa Inc., has the capability to provide demand response services through its manufacturing facilities and uniquely through its aluminum smelting facilities.

Studying such structures in different countries can reveal their attributes and features. In this study, key experts from the addictive behavior department of St George’s University of London and a group of Iranian specialists in the field of drug demand reduction first wrote on a sheet the name of organizations that are in charge of drug demand reduction. Then, via teamwork, they drew the connections between the organizations and compared the two charts to assess the relations between the member organizations. In total, 17 features of efficient structure were obtained as follow: multi-institutional nature, collaborative inter-institutional activities, clear and relevant inter-institutional and intra-institutional job description, the ability to share the experiences, virtual institutions activity, community-based associations activity, mutual relationships, the existence of feedback sys-tems, evaluation, changeability, the ability to collect data rapidly, being rooted in community, flexibility at the local and regional levels, connection with research centers, updated policymaking, empowering the local level, and seeking the maximum benefit and the minimum resources. Recognizing the characteristics of substance related organizations in various countries could help policy makers to improve drug demand reduction structures and to manage the wide-spread use of psychoactive substances more effectively. 

  8. Hypertension in developing countries.

    The past 2 decades have seen a considerable global increase in cardiovascular disease, with hypertension remaining by far the most common. More than one-third of adults in Africa are hypertensive; as in the urban populations of most developing countries. Being a condition that occurs with relatively few symptoms, hypertension remains underdetected in many countries; especially in developing countries where routine screening at any point of health care is grossly underutilized. Because hypertension is directly related to cardiovascular disease, this has led to hypertension being the leading cause of adverse cardiovascular outcomes, as a result of patients living, often unknowingly, with uncontrolled hypertension for prolonged periods of time. In Africa, hypertension is the leading cause of heart failure; whereas at global levels, hypertension is responsible for more than half of deaths from stroke, just less than half of deaths from coronary artery disease, and for more than one-tenth of all global deaths. In this review, we discuss the escalating occurrence of hypertension in developing countries, before exploring the strengths and weaknesses of different measures to control hypertension, and the challenges of adopting these measures in developing countries. On a broad level, these include steps to curb the ripple effect of urbanization on the health and disease profile of developing societies, and suggestions to improve loopholes in various aspects of health care delivery that affect surveillance and management of hypertension. Furthermore, we consider how the industrial sectors' contributions toward the burden of hypertension can also be the source of the solution.

    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.

    Commercial retail electricity rates commonly include a demand charge component, based on some measure of the customer’s peak demand. Customer-sited solar PV can potentially reduce demand charges, but the magnitude of these savings can be difficult to predict, given variations in demand charge designs, customer loads, and PV generation profiles. Moreover, depending on the circumstances, demand charges from solar may or may not align well with associated utility cost savings. Lawrence Berkeley National Laboratory (Berkeley Lab) and the National Renewable Energy Laboratory (NREL) are collaborating in a series of studies to understand how solar PV can reduce demand charge levels for a variety of customer types and demand charges designs. Previous work focused on residential customs with solar. This study, instead, focuses on commercial customers and seeks to understand the extent and conditions under which rooftop can solar reduce commercial demand charges. To answer these questions, we simulate demand charge savings for a broad range of commercial customer types, demand charge designs, locations, and PV system characteristics. This particular analysis does not include storage, but a subsequent analysis in this series will evaluate demand charge savings for commercial customers with solar and storage.

    Full Text Available The role, which money demand function plays in monetary policy formulation has attracted a lot of research studies to analyze this macroeconomic phenomenon. In the wake of current global and local economic and political upheavals, it is imperative to revisit the stability of money demand function. The study used the time series data and applied latest econometric techniques to find out the long run and short run money demand relationship. Moreover, all the three official monetary aggregates were used for finding out the most stable monetary demand relationship, which could provide correct signals for monetary policy formulation. The study found that broader monetary aggregate (M2 was the proper aggregate, which provided stable money demand function for Pakistan. The real GDP was positively related to the demand for real balances, while opportunity cost of money was negatively related. The study found that the role of financial innovation, in explaining the demand for money warrants attention in formulating monetary policy.

    The purpose of this study was to identify the demands of immigration among Chinese nurses that have immigrated to the USA. The relationship between the demands of immigration and length of stay in the USA was investigated also. A descriptive correlational study design was used. A convenience sample of 128 nurses was recruited. A self-administered survey was conducted using the demands of immigration scale developed by Aroian, along with a demographic questionnaire. The results showed Chinese immigrant nurses have high demands of immigration. There were significant negative relationships between the demands of immigration and length of stay in the USA. Immigration demands decreased as length of stay increased but remained high even for those who had been in the USA for > 5 years. This information is vital to health-care agencies designing and implementing adaptation programmes targeting these demands to facilitate Chinese nurses' adaptation process.

    2004-01-01

    The Republic of Pakistan is a South East Asian country with a population of over 140.7 million. Its population is fast growing and the majority (70%) live in rural areas with a feudal or tribal value system. The economy is dependent on agriculture and 35% of the population live below the poverty line. Islam is the main religion and 'mental illnesses' are stigmatized and widely perceived to have supernatural causes. The traditional healers along with psychiatric services are the main mental health service providers. The number of trained mental health professionals is small as compared to the population demands and specialist services are virtually non-existent. Lack of data on prevalence of various mental illnesses and monitory constraints are the major hurdles in the development of mental health services. A number of innovative programmes to develop indigenous models of care like the 'Community Mental Health Programme' and 'Schools Mental Health Programme' have been developed. These programmes have been found effective in reducing stigma and increase awareness of mental illness amongst the adults and children living in rural areas. Efforts by the government and mental health professionals have led to the implementation of a 'National Mental Health Policy' and 'Mental Health Act' in 2001. These aim at integrating mental health services with the existing health services, improving mental health care delivery and safeguarding the rights of mentally ill people. A favourable political will and the help of international institutions like the World Health Organization are required to achieve these aims.

    Multi-Object Spectrographs (MOS) are the major instruments for studying primary galaxies and remote and faint objects. Current object selection systems are limited and/or difficult to implement in next generation MOS for space and ground-based telescopes. A promising solution is the use of MOEMS devices such as micromirror arrays, which allow the remote control of the multi-slit configuration in real time. TNG is hosting a novelty project for real-time, on-demand MOS masks based on MOEMS programmable slits. We are developing a 2048×1080 Digital-Micromirror-Device-based (DMD) MOS instrument to be mounted on the Galileo telescope, called BATMAN. It is a two-arm instrument designed for providing in parallel imaging and spectroscopic capabilities. With a field of view of 6.8×3.6 arcmin and a plate scale of 0.2 arcsec per micromirror, this astronomical setup can be used to investigate the formation and evolution of galaxies. The wavelength range is in the visible and the spectral resolution is R=560 for a 1 arcsec object, and the two arms will have 2k × 4k CCD detectors. ROBIN, a BATMAN demonstrator, has been designed, realized and integrated. We plan to have BATMAN first light by mid-2016.

    The aim of this study was to assess physiological demands of competitive basketball by measuring oxygen consumption (VO2) and other variables during practice games. Each of 12 players (20.4 +/- 1.1 years) was monitored in a 20-min practice game, which was conducted in the same way as actual games with the presence of referees and coaches. VO2 was measured by a portable system during the game and blood lactate concentration (LA) was measured in brief breaks. Subjects were also videotaped for time-motion analysis. Female and male players demonstrated respective VO2 of 33.4 +/- 4.0 and 36.9 +/- 2.6 mL/kg/min and LA of 3.2 +/- 0.9 and 4.2 +/- 1.3 mmol/L in the practice games (P>0.05). They spent 34.1% of play time running and jumping, 56.8% walking, and 9.0% standing. Pre-obtained VO(2max) was correlated to VO(2) during play (r=0.673) and to percent of duration for running and jumping (r=0.935 and 0.962 for females and males, respectively). This study demonstrated a greater oxygen uptake for competitive basketball than that estimated based on a previous compendium. The correlation between aerobic capacity and activity level suggests the potential benefit of aerobic conditioning in basketball.

    This note explores the relationship between the price elasticity of demand and the R&D intensity of the product. We introduce the concept of R&D intensity into a standard Dixit-Stiglitz/Krugman-type setting. R&D activity is treated as a fixed cost of production. Within this framework, sectors...... with a higher R&D intensity show a lower price elasticity of demand. This proposition is confirmed by an empirical investigation of export demand for manufactured goods from major industrialised countries. Consequently, real exchange rate changes have an impact on the commodity structure of exports....

    Riganti, Andrea; Siciliani, Luigi; Fiorio, Carlo V

    2017-09-01

    Waiting times are a major policy concern in publicly funded health systems across OECD countries. Economists have argued that, in the presence of excess demand, waiting times act as nonmonetary prices to bring demand for and supply of health care in equilibrium. Using administrative data disaggregated by region and surgical procedure over 2010-2014 in Italy, we estimate demand and supply elasticities with respect to waiting times. We employ linear regression models with first differences and instrumental variables to deal with endogeneity of waiting times. We find that demand is inelastic to waiting times while supply is more elastic. Estimates of demand elasticity are between -0.15 to -0.24. Our results have implications on the effectiveness of policies aimed at increasing supply and their ability to reduce waiting times. Copyright © 2017 John Wiley & Sons, Ltd.

    Introduction: In the majority of developing countries, the volume of medical insurance services, provided by social insurance organizations is inadequate. Thus, supplementary medical insurance is proposed as a means to address inadequacy of medical insurance. Accordingly, in this article, we attempted to provide the context for expansion of this important branch of insurance through identification of essential factors affecting demand for supplementary medical insurance. Method: In this study, two methods were used to identify essential factors affecting choice of supplementary medical insurance including Classification and Regression Trees (CART) and Bayesian logit. To this end, Excel® software was used to refine data and R® software for estimation. The present study was conducted during 2012, covering all provinces in Iran. Sample size included 18,541 urban households, selected by Statistical Center of Iran using 3-stage cluster sampling approach. In this study, all data required were collected from the Statistical Center of Iran. Results: In 2012, an overall 8.04% of the Iranian population benefited from supplementary medical insurance. Demand for supplementary insurance is a concave function of age of the household head, and peaks in middle-age when savings and income are highest. The present study results showed greater likelihood of demand for supplementary medical insurance in households with better economic status, higher educated heads, female heads, and smaller households with greater expected medical expenses, and household income is the most important factor affecting demand for supplementary medical insurance. Conclusion: Since demand for supplementary medical insurance is hugely influenced by households’ economic status, policy-makers in the health sector should devise measures to improve households’ economic or financial access to supplementary insurance services, by identifying households in the lower economic deciles, and increasing their

  4. Voluntary medical male circumcision: a qualitative study exploring the challenges of costing demand creation in eastern and southern Africa.

    Directory of Open Access Journals (Sweden)

    Jane T Bertrand

    Full Text Available BACKGROUND: This paper proposes an approach to estimating the costs of demand creation for voluntary medical male circumcision (VMMC scale-up in 13 countries of eastern and southern Africa. It addresses two key questions: (1 what are the elements of a standardized package for demand creation? And (2 what challenges exist and must be taken into account in estimating the costs of demand creation? METHODS AND FINDINGS: We conducted a key informant study on VMMC demand creation using purposive sampling to recruit seven people who provide technical assistance to government programs and manage budgets for VMMC demand creation. Key informants provided their views on the important elements of VMMC demand creation and the most effective funding allocations across different types of communication approaches (e.g., mass media, small media, outreach/mobilization. The key finding was the wide range of views, suggesting that a standard package of core demand creation elements would not be universally applicable. This underscored the importance of tailoring demand creation strategies and estimates to specific country contexts before estimating costs. The key informant interviews, supplemented by the researchers' field experience, identified these issues to be addressed in future costing exercises: variations in the cost of VMMC demand creation activities by country and program, decisions about the quality and comprehensiveness of programming, and lack of data on critical elements needed to "trigger the decision" among eligible men. CONCLUSIONS: Based on this study's findings, we propose a seven-step methodological approach to estimate the cost of VMMC scale-up in a priority country, based on our key assumptions. However, further work is needed to better understand core components of a demand creation package and how to cost them. Notwithstanding the methodological challenges, estimating the cost of demand creation remains an essential element in deriving

    2016-05-01

    Full Text Available According to the modern theories of economic development – the take-off, backwardness, convergence and balanced growth hypothesis - the new industrialized states from Asia seem to have noticed the advantages of backwardness from which low income countries benefited, namely the possibility to take advantage of the latest technological discoveries of advanced countries, thus achieving a faster growth than the latter which operated closer to the technological border. The assimilation of appropriate technologies, however, required the efficient mobilization and allocation of resources and the improvement of human and physical capital. While the Western countries were confronted with crises generated by inflationary shocks and movements of speculative capital, the relative isolation of countries whose economy was planned by the world economy sheltered them until 1990, unemployment being practically non-existent. Asia's exceptional economic success is not only due to borrowing Western practices, but also to the fact that Asian societies maintained certain traditional features of their own culture - such as a strong work ethic - and integrated them in the modern business environment.

  15. Visualisation turns down energy demand

    Jensen, Ole Michael [Danish Building and Urban Research, Hoersholm (Denmark)

    2003-07-01

    After many energy saving campaigns, Danish families give the impression that they are conscious of energy consumption. Children have learned to turn off the light and adults to buy low-energy bulbs and household appliances. Questioned about their energy consumption and its fluctuations, the same people nevertheless confess to not really knowing. You pay your energy bill but pay no attention to the current consumption, or its level. Unlike other types of consumption, energy consumption is an almost invisible type of consumption. Nevertheless, as a secondary consumption it is much affected by primary consumption in the form of white goods, appliances, cars, food etc., the main purpose of which usually is visibility. This paper presents the result of an experiment to make the energy consumption visible. Meters in the flats showing actual electricity, heat and water consumption confront tenants with the consequences of their own behaviour. The experiment also investigates different set-ups concerning information and communication about energy consumption. Monthly consumption and levels of consumption compared within the neighbourhood are elements of this information. Also quarterly eco-accounting, with key-figures of consumption and environmental considerations like CO{sub 2} emission, are part of the information set-up. Within the first year of visualisation one case shows a 9% reduction of heat and a 22% reduction of electricity. The other cases seem to follow the same tendency. The philosophy of the experiment is that you must know your position in order to change it. You must know about the level of your own energy consumption in order to turn down energy demand.

    Full Text Available The Euro Area remains a well-known monetary union in the World. But the possibilities of creation of new monetary unions are discussed. It is spoken about NAFTA (Canada, Mexico and the United States or MERCOSUR (Argentina, Brazil, Paraguay, Uruguay and Venezuela. The aim of this paper is to assess the similarity of demand and supply shocks in the countries of NAFTA and MERCOSUR, and to compare it with the countries of the Euro Area. For these aims, correlation and structural vector autoregression methods are used. Methods are based on Blanchard and Quah (1989 and Bayoumi and Eichengreen (1993. We confirm the existence of core states and periphery states in the Euro Area with some exceptions. If we compare supply and demand shocks, we find more similarity in the case of supply shocks in the countries of the Euro Area. According to the results, the countries of NAFTA are more appropriate for the creation of monetary union than the countries of MERCOSUR. The countries of NAFTA achieve high correlation coefficients of supply and demand shocks (except Mexico for supply shocks.

  18. Health care system reform in developing countries

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available This article proposes a critical but non-systematic review of recent health care system reforms in developing countries. The literature reports mixed results as to whether reforms improve the financial protection of the poor or not. We discuss the reasons for these differences by comparing three representative countries: Mexico, Vietnam, and China. First, the design of the health care system reform, as well as the summary of its evaluation, is briefly described for each country. Then, the discussion is developed along two lines: policy design and evaluation methodology. The review suggests that i background differences, such as social development, poverty level, and population health should be considered when taking other countries as a model; ii although demand-side reforms can be improved, more attention should be paid to supply-side reforms; and iii the findings of empirical evaluation might be biased due to the evaluation design, the choice of outcome, data quality, and evaluation methodology, which should be borne in mind when designing health care system reforms.

    2015-08-01

    At the combined American Society for Apheresis (ASFA) Annual Meeting/World Apheresis Association (WAA) Congress in San Francisco, California, in April of 2014, the opening session highlighted the status of apheresis outside of the United States. The organizers invited physicians active in apheresis in countries not usually represented at such international gatherings to give them a forum to share their experiences, challenges, and expectations in their respective countries with regard to both donor and therapeutic apheresis. Apheresis technology is expensive as well as technically and medically demanding, and low and median income countries have different experiences to share with the rest of the world. Apheresis procedures also require resources taken for granted in the developed world, such as reliable electrical power, that can be unpredictable in parts of the developing world. On the other hand, it was obvious that there are significant disparities in access to apheresis within the same country (such as in Brazil), as well as between neighboring nations in Africa and South America. A common trend in the presentations from Brazil, Indonesia, Malaysia, Nigeria, and South Africa, was the need for more and better physicians and practitioners' training in the indications of the various apheresis modalities and patient oversight during the procedures. As ASFA and WAA continue to work together, and globalization allows for increased knowledge-sharing, improved access to apheresis procedures performed by qualified personnel with safety and high-quality standards will be increasingly available.

    This project describes the electricity demand and energy consumption management system and its application to the Smelter Plant of Southern Peru. It is composted of an hourly demand-forecasting module and of a simulation component for a plant electrical system. The first module was done using dynamic neural networks, with backpropagation training algorithm; it is used to predict the electric power demanded every hour, with an error percentage below of 1%. This information allows management the peak demand before this happen, distributing the raise of electric load to other hours or improving those equipments that increase the demand. The simulation module is based in advanced estimation techniques, such as: parametric estimation, neural network modeling, statistic regression and previously developed models, which simulates the electric behavior of the smelter plant. These modules allow the proper planning because it allows knowing the behavior of the hourly demand and the consumption patterns of the plant, in...

    With interiorizing day by day management thought that regarding customer as the centre, forecasting customer demand becomes more and more important. In the demand forecast of customer relationship management, the traditional forecast methods have very great limitation because much uncertainty of the demand, these all require new modeling to meet the demands of development. In this paper, the notion is that forecasting the demand according to characteristics of the potential customer, then modeling by it. The model first depicts customer adopting uniform multiple indexes. Secondly, the model acquires characteristic customers on the basis of data warehouse and the technology of data mining. The last, there get the most similar characteristic customer by their comparing and forecast the demands of new customer by the most similar characteristic customer.

  5. On the effects of monetary policy shocks in developing countries

    Directory of Open Access Journals (Sweden)

    Magda Kandil

    2014-06-01

    Full Text Available Using annual data for a sample of developing countries, the time-series evidence indicates the allocation of monetary policy shocks, both expansionary and contractionary, between price inflation and output growth. Subsequently, cross-country regressions evaluate factors that underlie the difference in these allocations and their implications. The real effects of monetary shocks increase as the elasticity of aggregate demand increases with respect to monetary shocks. Nonetheless, capacity constraints hamper the output adjustment to monetary shocks and increase price inflation. Across countries, trend output growth increases with the output response to monetary shocks. Consistent with the stabilizing function of monetary policy, the variability of output growth decreases in the face of monetary fluctuations across countries. In contrast, monetary fluctuations increase the trend and variability of price inflation across countries.

    Ujang, Z; Henze, M; Curtis, T; Schertenleib, R; Beal, L L

    2004-01-01

    This paper presents the existing philosophy, approach, criteria and delivery of environmental engineering education (E3) for developing countries. In general, environmental engineering is being taught in almost all major universities in developing countries, mostly under civil engineering degree programmes. There is an urgent need to address specific inputs that are particularly important for developing countries with respect to the reality of urbanisation and industrialisation. The main component of E3 in the near future will remain on basic sanitation in most developing countries, with special emphasis on the consumer-demand approach. In order to substantially overcome environmental problems in developing countries, E3 should include integrated urban water management, sustainable sanitation, appropriate technology, cleaner production, wastewater minimisation and financial framework.

  14. Modelling energy demand in the buildings sector within the EU

    Energy Technology Data Exchange (ETDEWEB)

    O Broin, Eoin

    2012-11-01

    In the on-going effort within the EU to tackle greenhouse gas emissions and secure future energy supplies, the buildings sector is often referred to as offering a large potential for energy savings. The aim of this thesis is to produce scenarios that highlight the parameters that affect the energy demands and thus potentials for savings of the building sector. Top-down and bottom-up approaches to modelling energy demand in EU buildings are applied in this thesis. The top-down approach uses econometrics to establish the historical contribution of various parameters to energy demands for space and water heating in the residential sectors of four EU countries. The bottom-up approach models the explicit impact of trends in energy efficiency improvement on total energy demand in the EU buildings stock. The two approaches are implemented independently, i.e., the results from the top-down studies do not feed into those from the bottom-up studies or vice versa. The explanatory variables used in the top-down approach are: energy prices; heating degree days, as a proxy for outdoor climate; a linear time trend, as a proxy for technology development; and the lag of energy demand, as a proxy for inertia in the system. In this case, inertia refers to the time it takes to replace space and water heating systems in reaction to price changes. The analysis gives long-term price elasticities of demand as follows: for France, -0.17; for Italy, -0.35; for Sweden, -0.27; and for the UK, -0.35. These results reveal that the price elasticity of demand for space and water heating is inelastic in each of these cases. Nonetheless, scenarios created for the period up to 2050 using these elasticities and an annual price increase of 3 % show that demand can be reduced by more than 1 % per year in France and Sweden and by less than 1 % per year in Italy and the UK. In the bottom-up modelling, varying rates for conversion efficiencies, heating standards for new buildings, end-use efficiency, and

  15. A Bound Test Approach to Cointegration of Tourism Demand

    Full Text Available Problem statement: Given the high contribution of tourism industry in the Malaysian economy, Malaysia has a vast view to increase its market share of the international tourist arrivals in the Asia Pacific region. Therefore, this study attempts to investigate the long run and short run demand for tourism from top ten markets (country. Approach: To accomplish this objective the ARDL bound test approach to cointegration was carried out for quarterly time series data from 1998:Q1 to 2007: Q3. A three-stage procedure followed to test the direction of causality. In the first stage the order of integration was tested using the Augmented Dickey-Fuller (ADF and Phillips Perron (PP unit root tests. The second stage involved testing for the existence of a long-run equilibrium relationship between arrivals, income, tourism price, tourism substitute price and travel cost. The third stage involved constructing standard Granger-type causality tests augmented with a lagged error-correction term where the series were cointegrated. Results: The result of ADF and PP unit root tests confirmed that all variables were stationary at first difference. In addition the results indicated that a long run relationship and between variables. Conclusion: The results indicated that tourists from these ten countries seem to be highly sensitive to the price and the alternative destinations are complementary to Malaysia. In addition the results showed that the outbreak of Severe Acute Respiratory Syndrome (SARS, 2003 had a negative affects significantly affected Malaysia’s tourism demand.

    Full Text Available This essay analyzes the differences between the economies of industrialized countriesand developing countries, which have important implications for macroeconomics interms of theory and policy. It considers the differences in macroeconomic objectives andexamines why the reach of macroeconomic policies is different in the two sets ofcountries. It argues that the distinction between short-run macroeconomic models andlong-term growth models is not quite appropriate for developing countries, wheremacroeconomic constraints on growth straddle time horizons and short-term policieshave long-term consequences. The essential hypothesis is that the nature of relationshipsand the direction of causation in macroeconomics, which shape analysis, diagnosis andprescription, depend on the institutional setting and not the analytical structure of models.And even if some laws of economics are universal, the functioning of economies can bemarkedly different. Therefore, economic theory and policy analysis should recognize,rather than ignore, such myriad differences.

    This study was carried out in Botswana, Tanzania and Zambia as part of the project `Climate Change Mitigation in Southern Africa` funded by the Danish International Development Agency (Danida). The project was conducted parallel to the UNEP/GEF project `Economics of Greenhouse Gas Limitations` which involved 8 other developing countries and 2 regional projects in Latin America and the SADC region. The limitation of greenhouse gas (GHG) emissions is a complex issue, intimately connected with economic development at local, national, regional and global levels. Key economic sectors such as energy, agriculture, industry and forestry all produce GHGs, and are likely to be affected directly and indirectly by any mitigation policy. The UNEP Greenhouse Gas Abatement Costing Studies, initiated in 1991, attempted to address these complex issues, developing a methodological framework and testing it through practical application in ten countries.

    2010-01-01

    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, 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 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 population betwee...

  6. Diagnostics for Developing Countries

    Directory of Open Access Journals (Sweden)

    Ruth McNerney

    2015-05-01

    Full Text Available Improving the availability of high quality diagnostic tests for infectious diseases is a global priority. Lack of access by people living in low income countries may deprive them of life saving treatment and reduces opportunities to prevent onward transmission and spread of the disease. Diagnostic laboratories are often poorly resourced in developing countries, and sparsely distributed. Improved access may be achieved by using tests that do not require laboratory support, including rapid tests for use at the point-of-care. Despite increased interest, few new in vitro diagnostic (IVD products reach the majority populations in low income countries. Barriers to uptake include cost and lack of robustness, with reduced test performances due to environmental pressures such as high ambient temperatures or dust. In addition to environmental factors test developers must consider the local epidemiology. Confounding conditions such as immunosuppression or variations in antigen presentation or genotype can affect test performance. Barriers to product development include access to finance to establish manufacturing capacity and cover the costs of market entry for new devices. Costs and delays may be inflated by current regulatory preregistration processes to ensure product safety and quality, and more harmonized approaches are needed.

  7. Marketing in developing countries.

    Pickering, A H

    1979-10-27

    I fully support the views of Mr. Chetley of War on Want on the marketing of infant foods in developing countries (Oct. 6, p. 747). My experience of eight years medical work in West Africa prompts me to broaden the debate. Advertising and promotional practices used by many European and American pharmaceutical companies are in many instances directed primarily to the non-professional and often poorly educated general public and appear to be geared simply to achieve the maximum volume of sales. Likewise, the cynical disregard of cigarette manufacturers for the dangers of smoking is very apparent in the way in which advertising and promotional campaigns are conducted in developing countries. Fifteen years ago cigarettes were largely imported items but now, certainly in one major West African country, there is a large and flourishing tobacco industry which appears to be run primarily by European interests and which is obviously not there for the health benefit of the people. Is it not a sad reflection on the morality of the society in which we live that, while striving to control unethical and undesirable practices at home, we make little or no effort to regulate those practices abroad when profit is the objective?

  8. Drivers of U.S. mineral demand

    Science.gov (United States)

    Sznopek, John L.

    2006-01-01

    Introduction: The word 'demand' has different meanings for different people. To some, it means their 'wants and needs,' to others it is what they consume. Yet, when considering economics, demand refers to the specific amounts of goods or services that individuals will purchase at various prices. Demand is measured over a given time period. It is determined by a number of factors including income, tastes, and the price of complementary and substitute goods. In this paper, the term consumption is used fairly synonymously with the term demand. Most mineral commodities, like iron ore, copper, zinc, and gravel, are intermediate goods, which means that they are used in the production of other goods, called final goods. Demand for intermediate goods is called derived demand because such demand is derived from the demand for final goods. When demand increases for a commodity, generally the price rises. With everything else held constant, this increases the profits for those who provide this commodity. Normally, this would increase profits of existing producers and attract new producers to the market. When demand for a commodity decreases, generally the price falls. Normally, this would cause profits to fall and, as a consequence, the least efficient firms may be forced from the industry. Demand changes for specific materials as final goods or production techniques are reengineered while maintaining or improving product performance, for example, the use of aluminum in the place of copper in long distance electrical transmission lines or plastic replacing steel in automobile bumpers. Substitution contributes to efficient material usage by utilizing cheaper or technically superior materials. In this way, it may also alleviate materials scarcity. If a material becomes relatively scarce (and thus more expensive), a more abundant (and less expensive) material generally replaces it (Wagner and others, 2003, p. 91).

  9. Modeling Gasoline Demand with Structural Breaks: New Evidence from Nigeria

    Directory of Open Access Journals (Sweden)

    Olusegun Akin Omisakin

    2012-01-01

    Full Text Available This paper extends previous studies in modeling and estimating demand for gasoline for Nigeria from 1977 to 2008. The ingenious attempt of this study, contrast to earlier studies on Nigeria and other developing countries, lies in its assumption of structural breaks in the long run relationship among the variables employed. The study tests for the possibility of structural breaks/regime shifts and parameter instability in the gasoline demand function in Nigeria using more recent and robust techniques. While the conventional residual-based cointegration tests employed fail to identify any meaningful long-run relationship in the gasoline function, the Gregory-Hansen structural break cointegration approach confirms the cointegration relationships despite the breakpoints. The elasticity estimates also follow the a priori expectations being inelastic both in the long- and short-run for both price and income. Having identified plausible breaks in the systems, the test does suggest that a structural break in the cointegration vector is important and needs to be taken care of in the specification of gasoline demand functions in Nigeria. It is envisaged, therefore, that substantial policy lessons would be drawn from the findings of this study especially in the current phase of energy industry deregulation in Nigeria.

  10. Multikanban model for disassembly line with demand fluctuation

    Udomsawat, Gun; Gupta, Surendra M.; Al-Turki, Yousef A. Y.

    2004-02-01

    In recent years, the continuous growth in consumer waste and dwindling natural resources has seriously threatened the environment. Realizing this, several countries have passed regulations that force manufacturers not only to manufacture environmentally conscious products, but also to take back their used products from consumers so that the components and materials recovered from the products may be reused and/or recycled. Disassembly plays an important role in product recovery. A disassembly line is perhaps the most suitable setting for disassembly of products in large quantities. Because a disassembly line has a tendency to generate excessive inventory, employing a kanban system can reduce the inventory level and let the system run more efficiently. A disassembly line is quite different from an assembly line. For example, not only can the demand arrive at the last station, it can also arrive at any of the other stations in the system. The demand for a component on the disassembly line could fluctuate widely. In fact, there are many other complicating matters that need to be considered to implement the concept of kanbans in such an environment. In this paper, we discuss the complications that are unique to a disassembly line. We discuss the complications in utilizing the conventional production control mechanisms in a disassembly line setting. We then show how to overcome them by implementing kanbans in a disassembly line setting with demand fluctuation and introduce the concept of multi-kanban mechanism. We demonstrate its effectiveness using a simulation model. An example is presented to illustrate the concept.

    Full Text Available The Intercultural Bilingual Education System in Ecuador is guaranteed by the Constitution and assured by the Organic Law of Intercultural Bilingual Education, in a process that took a few decades to the indigenous population. The Ecuadorian state currently counts with a Model of Intercultural Bilingual Education that has its own structure, attached to the Ministry of Education and responsible for generating educational guidelines for 35 indigenous nationalities that coexist in the country. The objective of this study is to analyze the social demand for the Bachelor in Intercultural Bilingual Education, offered by Universidad Politécnica Salesiana. The analysis was carried out through two studies, one of them quantitative, addressed to educational institutions, and the other one qualitative and directed to government officials. The research objectives were to determine the need for graduates in Intercultural Bilingual Education, identify the desired profile of graduates of the career and academic requirements for a successful career. The results highlighted that the current presence of professionals in bilingual intercultural education is 0,65 per institution, with an average necessity of 1,85, which determines the existence of a demand in the next three years of 3 315 professionals. The main conclusion is that there is a significant demand for this career. Although the deficiencies of the current educational system, there in a strengthening trend.

    Describe a tool to estimate demand for benznidazole and nifurtimox to treat Chagas disease, and report on its implementation in a group of Latin American countries. The project was carried out in the following stages: 1) development of a tool to estimate demand, and definition of the evaluation and decision variables to estimate demand 2) data collection via a questionnaire completed by representatives of control programs, complemented with data from the literature; 3) presentation of the tool, followed by validation, and adaptation by representatives of the control programs in order to plan drug procurement for 2012 and 2013; and 4) further analysis of the obtained data, especially regarding benznidazole, and comparison of country estimates. Fourteen endemic countries of Latin America took part in the third stage, and a consolidated estimate was made. The number of estimated treatments, based on the number of tablets per treatment established in the regimen of reference was: 867 in the group under 1 year of age; 2 042 835 in the group from 1 to 15 years old; 2 028 in the group from 15 to 20 years old; and 10 248 in adults over 20. This means that it is possible to provide benznidazole to less than 1% of people for whom treatment is indicated. The development and systematic use of demand management tools can play a key role in helping to provide access to the anti-Chagas drugs. There is a significant gap between the projected demand for drugs and current estimates of prevalence rates.

    Full Text Available Orientation: Understanding the job demands and resources experienced by workers in an agricultural organisation.Research purpose: The objective of this study was to examine the validity and reliability of the Adapted Job Demands and Resources Scale (AJDRS as well as to establish prevalent job demands and resources of employees in an agricultural organisation. Demographic differences were also investigated.Motivation of the study: The agricultural sector of any national economy plays a very important role in the overall welfare of the country. Identifying the prevalent job demands and resources in an agricultural organisation is therefore of paramount importance since the negative consequences of employees experiencing very demanding jobs with few resources have been well documented in stress literature.Research approach, design and method: A cross-sectional survey design was used. The sample consisted of 443 employees in an agricultural organisation. The AJDRS was used to measure the research variables.Main findings: The findings of this research show evidence for the factorial validity and reliability of the AJDRS. Statistical differences were found with regard to the job demands and resources experienced by employees in different positions.Practical/managerial implications: Interventions to improve the perceived job demands and resources in the organisation should focus on physical resources (equipment.Contribution/value-add: This study contributes to knowledge concerning the job demands and resources that are prevalent in an agricultural organisation in South Africa.

  17. Communication technologies for demand side management

    Energy Technology Data Exchange (ETDEWEB)

    Uuspaeae, P. [VTT Energy, Espoo (Finland)

    1998-08-01

    The scope of this research is data communications for electric utilities, specifically for the purposes of Demand Side Management (DSM). Demand Side Management has the objective to change the customer`s end use of energy in a manner that benefits both the customer and the utility. For example, peak demand may be reduced, and the peak demand may be relocated to off peak periods. Thus additional investments in generation and network may be avoided. A number of Demand Side Management functions can be implemented if a communication system is available between the Electric Utility and the Customer. The total communication capacity that is needed, will depend on several factors, such as the functions that are chosen for DSM, and on the number and type of customers. Some functions may be handled with one-way communications, while some other functions need to have two-way communication

  18. A dawning demand for a new cannabis policy: A study of Swedish online drug discussions.

    Science.gov (United States)

    Månsson, Josefin

    2014-07-01

    This study examines how online discussions on drug policy are formulating an oppositional cannabis discourse in an otherwise prohibitionist country like Sweden. The focus of the paper is to identify demands for an alternative cannabis policy as well as analysing how these demands are linked to governance. The empirical material is 56 discussion-threads from the online message-board Flashback Forum that were active during the first eight months of 2012. Discourse theory was used to locate the discourse, and governmentality theory was used to locate the political belonging of the discourse. On Flashback Forum demands for a new cannabis policy are articulated in opposition to Swedish prohibitionist discourse. The oppositional discourse is constructed around the nodal points cannabis, harm, state and freedom that fill legalisation/decriminalisation/liberalisation with meaning. The nodal points are surrounded by policy demands that get their meaning through the particular nodal. These demands originate from neo-liberal and welfarist political rationalities. Neo-liberal and welfarist demands are mixed, and participants are simultaneously asking for state and individual approaches to handle the cannabis issue. Swedish online discourse on cannabis widens the scope beyond the confines of drug policy to broader demands such as social justice, individual choice and increased welfare. These demands are not essentially linked together and many are politically contradictory. This is also significant for the discourse; it is not hegemonised by a political ideology. The discourse is negotiated between the neo-liberal version of an alternative policy demanding individual freedom, and the welfarist version demanding social responsibility. This implies the influence of the heritage from the social-democratic discourse, centred on state responsibility, which have been dominating Swedish politics in modern times. Consequently, this study refutes that the demand for a new cannabis

  19. The UK-DALE dataset, domestic appliance-level electricity demand and whole-house demand from five UK homes.

    Science.gov (United States)

    Kelly, Jack; Knottenbelt, William

    2015-01-01

    Many countries are rolling out smart electricity meters. These measure a home's total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the 'ground truth' demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

  20. Coordination of Energy Efficiency and Demand Response

    Energy Technology Data Exchange (ETDEWEB)

    Goldman, Charles; Reid, Michael; Levy, Roger; Silverstein, Alison

    2010-01-29

    This paper reviews the relationship between energy efficiency and demand response and discusses approaches and barriers to coordinating energy efficiency and demand response. The paper is intended to support the 10 implementation goals of the National Action Plan for Energy Efficiency's Vision to achieve all cost-effective energy efficiency by 2025. Improving energy efficiency in our homes, businesses, schools, governments, and industries - which consume more than 70 percent of the nation's natural gas and electricity - is one of the most constructive, cost-effective ways to address the challenges of high energy prices, energy security and independence, air pollution, and global climate change. While energy efficiency is an increasingly prominent component of efforts to supply affordable, reliable, secure, and clean electric power, demand response is becoming a valuable tool in utility and regional resource plans. The Federal Energy Regulatory Commission (FERC) estimated the contribution from existing U.S. demand response resources at about 41,000 megawatts (MW), about 5.8 percent of 2008 summer peak demand (FERC, 2008). Moreover, FERC recently estimated nationwide achievable demand response potential at 138,000 MW (14 percent of peak demand) by 2019 (FERC, 2009).2 A recent Electric Power Research Institute study estimates that 'the combination of demand response and energy efficiency programs has the potential to reduce non-coincident summer peak demand by 157 GW' by 2030, or 14-20 percent below projected levels (EPRI, 2009a). This paper supports the Action Plan's effort to coordinate energy efficiency and demand response programs to maximize value to customers. For information on the full suite of policy and programmatic options for removing barriers to energy efficiency, see the Vision for 2025 and the various other Action Plan papers and guides available at www.epa.gov/eeactionplan.

  1. New approaches for estimating the demand for children.

    Science.gov (United States)

    Lightbourne R

    1987-01-01

    This paper estimates the instantaneous demand for children during each month of the reproductive span. It does so by analyzing survey data on the desire to conceive as a function of 2 variables: parity and months elapsed since entry to each parity. Based on the estimates of the instantaneous demand for children, the paper develops a unified model for estimating desired conception waits, desired birth intervals, number of births wanted over a lifetime, the desired level of contraceptive prevalence, and the unmet need for contraception. The model is applied to Ecuador, Ghana, Malaysia and the Republic of Korea. In 3 of the 4 countries, substantial numbers of women desire very long birth intervals; if that preference for long birth intervals were realized, fertility would be substantially reduced. In all 4 countries there is a fraction of women whose desired conception wait is so short as to endanger maternal health and raise child mortality. In all 4 countries, the mean number of children that women would bear if they conceived only when they wanted to is very much lower than the contemporaneous total fertility rate and is substantially lower than desired family size. The estimates indicate that if women fully implemented their postponing and terminating preferences, fertility would decline by 58% in Ecuador, 25% in Ghana, 42% in Malaysia and 31% in the Republic of Korea. The level of contraceptive prevalence that would come into being if women implemented their postponing and terminating preferences is much higher than the actual level of contraceptive prevalence, thus indicating high levels of unmet need for contraceptives. These findings have implications for population policy in the areas of maternal health and child mortality, fertility and family planning.

  2. Greywater reuse: A strategy for water demand management in Harare?

    Science.gov (United States)

    Madungwe, Emaculate; Sakuringwa, Saniso

    Greywater is wastewater from baths, sinks and washing machines, accounting for about 60% of the outflow from homes. It contains little pathogens and 90% less nitrogen than toilet water, so does not require the same treatment process. With the increasing demand for freshwater, its use may reduce irrigation water needs, increasing its availability of freshwater for other primary uses. Agriculture is the main water consumer in Africa, which cannot be compromised due to its role in domestic food security and export supplies. The purpose of this paper is to demonstrate findings of the research done on benefits of greywater reuse in some countries, applicable to African countries. In Australia, greywater reuse has reduced freshwater demand, strain on wastewater treatment plants and energy consumption. Aquifer recharge has improved due to increased infiltration flows from greywater uses. In Lebanon, greywater is a valuable resource for encouraging plant growth from nutrients that may otherwise have been wasted. Palestine shares similar climate and water scarcity conditions with most arid sub-Saharan African countries, yet utilizes grey water in production of crops and citrus fruits. Thus use of grey water should be possible in African cities such as Harare, where nearly two thirds of the population rely on agriculture for livelihoods. The problem of blue green algae in sewerage ponds and water reservoirs is significantly reduced by household reuse of grey water in Mexico. Water savings are increased and expenses reduced, as illustrated by the reduction in consumption of municipality freshwater supplies in South African urban areas. Rural communities and schools in Namibia and Egypt have raised funds from grey water reuse in banana plantations. A possible constraint to this strategy could be the unavailability of appropriate technology for primary treatment of grey water before reuse. This strategy may pose health risks where water quality tests are unknown or unavailable

  8. The electricity sector susceptibility of European countries to climate change

    Klein, Daniel R.; Olonscheck, Mady; Walther, Carsten; Kropp, Jürgen P.

    2014-05-01

    Due to the close relationship between electricity consumption, production and temperature, the electricity systems of countries are particularly susceptible to climate change. Based on a number of quantitative influencing factors, we provide a relative index for 21 European countries. This allows relevant stakeholders to identify the main influencing factors that determine the electricity system susceptibility of their country. The index was determined using 14 influencing factors that include those that increase or decrease susceptibility. This includes information on monthly mean temperature, electricity consumption, import, export and production by energy source for the period 2000-2011. Moreover, we consider the results of nine global climate models regarding future temperature changes as well as data on air conditioner prevalence by country. A quantitative relative ranked index describing the susceptibility of each country's electricity system is provided. In both Luxembourg and Greece, which top the list, the inability to meet electricity demand with inland production as well as a heavy reliance on combustible fuel electricity production explain part of the high relative susceptibility. Summer electricity consumption (another influencing factor) is expected to increase in Greece where current relatively warm temperatures, in the context of the countries included in this study, are expected to increase in the future. Comparatively, Norway was the least susceptible country based on our index. Norway is expected to benefit from rising projected temperatures, which will decrease winter electricity consumption and limit susceptibility. Furthermore, Norway's current electricity production exceeds consumption demand and is largely based on hydro, which also decreases susceptibility. The findings of this study enable policy makers, scientists and energy managers to examine the most important influencing factors that increase susceptibility and focus their adaptation

    Population education country programs in the countries of India, Malaysia, Nepal, the Philippines, and Sri Lanka are reviewed. In India the machinery is beginning to roll for the nationwide implementation of a 3-year national population education project. A variety of strategies will be used at the national and state levels using existing facilities and infrastructure for implementing various aspects of the program. Recommendations and proposed project activities arrived at during 2 workshop/training programs are outlined. The Malaysian population education program recently developed a working draft of the scope, content, and objectives of population education at the primary and lower and upper secondary levels. This working draft is being pretested among teachers and curriculum developers, and, once revised, it will serve as the overall guiding framework for those responsible for preparing curriculum and instructional materials on population education. The population education program in Nepal will be implemented by 3 units: Curriculum, Textbook, Supervision, and Development Center; Tribhuvan University; and Division of Adult Education. The longterm objective is to institutionalize population education in the formal and nonformal education programs including the university. The Population Education Program of the Philippines has prepared a reader in Filipino for grade 3 pupils. Population education in the country has been promoted to a lesser degree in private than in public schools. the Institutional Development Program of the Population Center Foundation conducted a Summer Institute in Instructional Product Development for the primary purpose of institutionalizing population in the social science curriculum at the tertiary level. The population education program of Sri Lanka will undergo a revival in the recently approved 2-year project agreement between Sri Lanka's government and the United Nations Fund for Population Activities.

    Assessment of water availability and demand in Lake Guiers, SenegalWater resources are critical to economic growth and social development. In most African countries, supply of drinking water to satisfy population needs is a key issue because of population growth and climate and land use change. During the last three decades, increasing population, changing patterns of water demand, and concentration of population and economic activities in urban areas has pressurize Senegal's freshwater resources. To overcome this deficit, Senegal turned, to the exploitation of the Lake Guiers. It is the sole water reservoir which can be used extensively as a stable freshwater. Its water is use for irrigating crops and sugar refinery and as a drinking water resource for urban centres, including Dakar, the capital city of Senegal, as well as for the local population and animal herds. To ensure sustainability, a greater understanding of Lake Guiers's water resources and effective management of its use will be required. In this study we developed and quantified future water situation (water availability and demand) in Lake Guiers under scenarios of climate change and population growth until 2050, using the water management model WEAP (Water Evaluation And Planning system). The results show that the pressure on Lake Guiers's water resources will increase, leading to greater competition between agriculture and municipal demand site. Decreasing inflows due to climate change will aggravate this situation. WEAP results offer basis to assister lake Guiers water resources manager for an efficient long-term planning and management.

    Full Text Available Andrei Shleifer and Daniel Treisman recently rendered a summary verdict on the post Soviet Russian transition experience finding that the Federation had become a normal country with the west's assistance, and predicting that it would liberalize and develop further like other successful nations of its type. This essay demonstrates that they are mistaken on the first count, and are likely to be wrong on the second too. It shows factually, and on the norms elaborated by Pareto, Arrow and Bergson that Russia is an abnormal political economy unlikely to democratize, westernize or embrace free enterprise any time soon

  12. The Netherlands: country profile.

    1985-12-01

    This discussion of the Netherlands covers the country's cities and regions, population growth, households and families, housing, contruction, and spatial planning; ethnicity and religion; education; labor force and income; consumption; and transport and communications. As a small and mineral poor nation with a seafaring tradition, the Netherlands survives on foreign trade. In 1983, total export earnings amounted to nearly 62% of the entire national income. Over 72% of Dutch exports go to other member countries of the European Economic Community (EEC), but imports are more diversified, with 47% originating outside the EEC. Since 1848, the Netherlands has been a constitutional monarchy with a parliamentary form of government. As such, it is one of the most stable democracies in the world. The main administrative units are the 11 provinces, of which Noord-Holland and Zuid-Holland are the most populous and economically most important. Amsterdam remains the commercial center of the country, but its role as the principal port city has been taken over by Rotterdam. No community has more than 700,000 inhabitants, but the country as a whole is highly urbanized because of the large numbers of medium-sized cities. In 1983 the population of the Netherlands totaled 14.34 million, compared to 5.10 million at the turn of the century. In 1965, the total fertility rate was 3.0. The death rate has virtually stabilized at 8/1000. The Dutch life expectancy stands at 72.7 years for men and 79.4 for women (1983). Natural increase has already dropped to 0.4% a year. Apart from the slight impact of net immigration, the positive growth rate reflects the large proportion (53%) of the population in its reproductive years. Mean household sizes in the 11 provinces vary from 2.5 in Noord-Holland (in 1981) to nearly 3 in Overijssel and Noord-Brabant, whereas the proportion of 1 person households ranges from 16% in Drenthe and 17% in the somewhat traditionalist southern provinces of Limburg and

    In 1991-1992, Via Libre, a nongovernmental organization (NGO), developed an information program for the general public in Lima using a portable pavilion. The metallic structure is 32 square meters and houses 30 posters with prevention messages. Collaboration with another NGO, Instituto Generacion, resulted in the production of a 7 minute video of basic information that is shown continuously at the pavilion. Facilitators distribute printed materials. Occasionally, a third NGO, Asociacion Germinal, provides street clowns who carry prevention messages to accompany the exhibit. Due to positive public response, the exhibit became "The Information Traveling Pavilion" in 1993; the exhibit has traveled to more than seven cities throughout Peru. Via Libre staff provide local health workers with information update courses and counseling workshops in order to respond to increased public demands for information and support following the activities. 75 private enterprises have provided support for the program. Radio and television collaborate in publicizing the activities.

    Declines in insect pollinators across Europe have raised concerns about the supply of pollination services to agriculture. Simultaneously, EU agricultural and biofuel policies have encouraged substantial growth in the cultivated area of insect pollinated crops across the continent. Using data from 41 European countries, this study demonstrates that the recommended number of honeybees required to provide crop pollination across Europe has risen 4.9 times as fast as honeybee stocks between 2005 and 2010. Consequently, honeybee stocks were insufficient to supply >90% of demands in 22 countries studied. These findings raise concerns about the capacity of many countries to cope with major losses of wild pollinators and highlight numerous critical gaps in current understanding of pollination service supplies and demands, pointing to a pressing need for further research into this issue.

    2007-01-01

    There is relatively little known about the demand for allograft tissues in Canada. The Canadian Council for Donation and Transplantation (CCDT) is a national advisory body that undertook a comprehensive "market survey" to estimate surgical demand for human allograft tissues in Canada. The report "Demand for Human Allograft Tissue in Canada" reflects survey results sent to 5 prominent User Groups. User Groups were identified as orthopaedic surgeons; neurosurgeons; corneal transplant surgeons; plastic surgeons, specifically those at Canadian Burn Units; and cardiac surgeons (adult and paediatric surgery). The demand for allograft grafts was determined and then extrapolated across the total User Group and then increases in allograft tissue use over the next 1-2 years across User Groups were predicted. The overall response rate for the survey was 21.4%. It varied from a low of 19.6% for the orthopaedic survey to a high of 40.5% for the corneal survey. The estimated current demand for allograft tissue in Canada ranges from a low of 34,442 grafts per year to a high of 62,098 grafts per year. The predicted increase in use of allograft tissue over the next 1-2 year period would suggest that annual demand could rise to somewhere in the range of 42,589-72,210 grafts. The highest rated preferences (98% and 94%) were for accredited and Canadian tissue banks, respectively. This study represents a key step in addressing the paucity of information concerning the demand for allograft tissue in Canada.

    2016-11-01

    The present study aimed to quantify the demand of seven generic, closed agility drills. Twenty males with experience in invasion sports volunteered to participate in this study. They performed seven, closed agility drills over a standardised 30-m distance. Physical demand measures of peak velocity, total foot contacts, peak impacts, completion time, and maximum heart rate were obtained via the use of wearable sensor technologies. A subjective rating of perceived exertion (RPE) was also obtained. All measures, with the exception of maximum heart rates and RPE were able to delineate drills in terms of physical and physiological demand. The findings of this study exemplify the differences in demand of agility-type movements. Drill demand was dictated by the type of agility movement initiated with the increase in repetitiveness of a given movement type also contributing to increased demand. Findings from this study suggest agility drills can be manipulated to vary physical and physiological demand. This allows for the optimal application of training principles such as overload, progression, and periodisation.

    The International Tribunal for Children's Rights (ITCR) was established to conduct individual and public inquiries and propose concrete solutions to violations of children's rights. This article reports on the efforts of the ITCR to enforce extraterritorial laws in response to the international dimension of child sex exploitation. The primary message being advocated is that travelers cannot go to foreign countries to engage in sexual crimes against children, evade criminal prosecution in the countries where the crimes are committed and then expect to return home without any consequences. In its first public hearings held in Paris, France to the address the effectiveness of extraterritorial legislation, governments and nongovernmental organizations informed the ITCR about their attempts to halt child sexual exploitation. Several changes needed to make extraterritorial laws more effective were cited. These include public awareness-raising; supporting existing instruments; application of preventive approaches to child abuse; and sensitizing and motivating judicial, police and administrative authorities to provide for the needs to fight child sex tourism.

    2011-06-01

    Full Text Available The article represents the results of research devoted to the problem of demand for labour force projection. The two main priorities of Russian economic development — modernization and innovation — are declared as the factors influencing labour market in a rather intrinsic and specific way. The research of dependence between GDP growth rate per occupied in the most developed countries is conducted and shows the positive influence the innovation process imposes on the demand for labour force. The particular problem is proved to be semi-structured. The selforganisation approach to this problem is proposed and helps to detect that the main shaping process of labour market dynamics is industry modernization. The trend of modernization influence on demand for labour force is revealed and taken under consideration while developing the mathematical model, enabling to predict the demand for labour force with not more than 2% mean absolute percentage error.

    Buchan, J; O'May, F

    This paper reviews research on the supply of, and demand for nurse. It examines the utility of various data indicators of nursing shortages and highlights potential shortcomings in their application. The paper also assesses the links between nurses' pay and nurses' labour market behaviour, reviewing the comparatively few papers that have taken a UK perspective on this issue. The current mismatch between nurses' supply and demand in the UK is also examined, with the clear indication that there is potential for an increase in mismatch as demand increases, while future supply appears problematic.

    An estimate of the world tungsten demand and supply until 2018 has been made. The figures were obtained by extrapolating from past trends of tungsten production from1905, and its demand from 1964. In addition, estimate suggestions of major production and investment companies were taken into account with regard to implementations of new projects for mining of tungsten or possible termination of its standing extraction. It can be assumed that tungsten supply will match demand by 2018. This suggestion is conditioned by successful implementation of new tungsten extraction projects, and full application of tungsten recycling methods.

    Full Text Available Eco-innovation globally emerged as an effort to implement sustainable development. States and firms established and implemented policies and strategies for eco-innovation as one route to achieving sustainable development. Eco-innovation has been facilitated in developed countries, specifically OECD members and European countries, through action plans. Recently, eco-innovation policies have emerged in developing countries. Thus, this study analyzes eco-innovation policies in Asian countries. Policies related to eco-innovation in 17 Asian countries were investigated using policy instrument categories. National policies for eco-innovation were interpreted and compared with development stage classifications. The results indicate that there are similar and different policy approaches to eco-innovation in Asian countries. Given the balance between a technology push (supply side and a market pull (demand side in policy instruments for eco-innovation, 17 countries were identified by four categories: leaders, followers, loungers, and laggards. The results provide insight for designing national strategies for eco-innovation in Asia’s developing countries. Therefore, this research contributes to facilitating and diffusing eco-innovation toward sustainability in Asia.

    Water is not an infinite resource and demand from irrigation, household and industry is constantly increasing. This study focused on including global water availability including environmental flow requirements with water withdrawal from irrigation and other sectors at a monthly time-step in the GLOBIOM model. This model allows re-adjustment of land-use allocation, crop management, consumption and international trade. The GLOBIOM model induces an endogenous change in water price depending on water supply and demand. In this study, the focus was on how the inclusion of water resources affects land-use and, in particular, how global change will influence repartition of irrigated and rainfed lands at global scale. We used the climate change scenario including a radiative forcing of 8.5 W/m2 (RCP8.5), the socio-economic scenario (SSP2: middle-of-road), and the environmental flow method based on monthly flow allocation (the Variable Monthly Flow method) with high and low restrictions. Irrigation withdrawals were adjusted to a monthly time-step to account for biophysical water limitations at finer time resolution. Our results show that irrigated land might decrease up to 40% on average depending on the choice of EFR restrictions. Several areas were identified as future hot-spots of water stress such as the Mediterranean and Middle-East regions. Other countries were identified to be in safe position in terms of water stress such as North-European countries. Re-allocation of rainfed and irrigated land might be useful information for land-use planners and water managers at an international level to decide on appropriate legislations on climate change mitigation/adaptation when exposure and sensitivity to climate change is high and/or on adaptation measures to face increasing water demand. For example, some countries are likely to adopt measures to increase their water use efficiencies (irrigation system, soil and water conservation practices) to face water shortages, while

    This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of the resolution of uncertainty found in models with heterogeneity...... to forecast unknown demands in untested destinations. The option to forecast demands causes firms to delay exporting in order to gather more information about foreign demand. Third, since uncertainty is resolved after entry, many firms enter a destination and then exit after learning that they cannot profit....... This prediction reconciles the high rate of exit seen in the first years of exporting. Finally, when faced with multiple destinations to which they can export, many firms will choose to sequentially export in order to slowly learn more about its chances for success in untested markets....

    Wing Kwong Chung

    2013-01-01

    Full Text Available The energy of a space station is a precious resource, and the minimization of energy consumption of a space manipulator is crucial to maintain its normal functionalities. This paper first presents novel gaits for space manipulators by equipping a new gripping mechanism. With the use of wheels locomotion, lower energy demand gaits can be achieved. With the use of the proposed gaits, we further develop a global path planning algorithm for space manipulators which can plan a moving path on a space station with a minimum total energy demand. Different from existing approaches, we emphasize both the use of the proposed low energy demand gaits and the gaits composition during the path planning process. To evaluate the performance of the proposed gaits and path planning algorithm, numerous simulations are performed. Results show that the energy demand of both the proposed gaits and the resultant moving path is also minimum.

    2017-05-01

    Information asymmetry and the bullwhip effect have been serious problems in the tourism supply chain. Based on platform theory, this paper established a mathematical model to explore the inner mechanism of a platform's influence on stakeholders' ability to forecast demand in tourism. Results showed that the variance of stakeholders' demand predictions with a platform was smaller than the variance without a platform, which meant that a platform would improve predictions of demand for stakeholders. The higher information-processing ability of the platform also had other effects on demand forecasting. Research on the inner logic of the platform's influence on stakeholders has important theoretical and realistic value. This area is worthy of further study.

    Demand response and energy storage resources present potentially important sources of bulk power system services that can aid in integrating variable renewable generation. While renewable integration studies have evaluated many of the challenges associated with deploying large amounts of variable wind and solar generation technologies, integration analyses have not yet fully incorporated demand response and energy storage resources. This report represents an initial effort in analyzing the potential integration value of demand response and energy storage, focusing on the western United States. It evaluates two major aspects of increased deployment of demand response and energy storage: (1) Their operational value in providing bulk power system services and (2) Market and regulatory issues, including potential barriers to deployment.

    Full Text Available Objective: To describe the background and strategy required for the prevention of blindness from glaucoma in developing countries. Materials and Methods: Extrapolation of existing data and experience in eye care delivery and teaching models in an unequally developed country (India are used to make recommendations. Results: Parameters like population attributable risk percentage indicate that glaucoma is a public health problem but lack of simple diagnostic techniques and therapeutic interventions are barriers to any effective plan. Case detection rather than population-based screening is the recommended strategy for detection. Population awareness of the disease is low and most patients attending eye clinics do not receive a routine comprehensive eye examination that is required to detect glaucoma (and other potentially blinding eye diseases. Such a routine is not taught or practiced by the majority of training institutions either. Angle closure can be detected clinically and relatively simple interventions (including well performed cataract surgery can prevent blindness from this condition. The strategy for open angle glaucoma should focus on those with established functional loss. Outcomes of this proposed strategy are not yet available. Conclusions: Glaucoma cannot be managed in isolation. The objective should be to detect and manage all potential causes of blindness and prevention of blindness from glaucoma should be integrated into existing programs. The original pyramidal model of eye care delivery incorporates this principle and provides an initial starting point. The routine of comprehensive eye examination in every clinic and its teaching (and use in residency programs is mandatory for the detection and management of potentially preventable blinding pathology from any cause, including glaucoma. Programs for detection of glaucoma should not be initiated unless adequate facilities for diagnosis and surgical intervention are in place and

    2013-11-01

    Occupational, social and recreational routines follow temporal patterns, as does the onset of certain acute medical diseases and injuries. It is not known if the temporal nature of injury and disease transfers into patterns that can be observed in ambulance demand. This review examines eligible study findings that reported temporal (time of day, day of week and seasonal) patterns in ambulance demand. Electronic searches of Medline and Cumulative Index of Nursing and Allied Health Literature were conducted for papers published between 1980 and 2011. In addition, hand searching was conducted for unpublished government and ambulance service documents and reports for the same period. 38 studies examined temporal patterns in ambulance demand. Six studies reported trends in overall workload and 32 studies reported trends in a subset of ambulance demand, either as a specific case type or demographic group. Temporal patterns in overall demand were consistent between jurisdictions for time of day but varied for day of week and season. When analysed by case type, all jurisdictions reported similar time of day patterns, most jurisdictions had similar day of week patterns except for out-of-hospital cardiac arrest and similar seasonal patterns, except for trauma. Temporal patterns in case types were influenced by age and gender. Temporal patterns are present in ambulance demand and importantly these populations are distinct from those found in hospital datasets suggesting that variation in ambulance demand should not be inferred from hospital data alone. Case types seem to have similar temporal patterns across jurisdictions; thus, research where demand is broken down into case types would be generalisable to many ambulance services. This type of research can lead to improvements in ambulance service deliverables.

    We estimate the price elasticity of water demand with household-level data, structurally modeling the piecewise-linear budget constraints imposed by increasing-block pricing. We develop a mathematical expression for the unconditional price elasticity of demand under increasing-block prices and compare conditional and unconditional elasticities analytically and empirically. We test the hypothesis that price elasticity may depend on price structure, beyond technical differences in elasticity co...

    1998-04-01

    Long-term forecast of power and energy demand become an important base of investment plan of the energy supply sector, and a study based on value data is indispensable since the expansion of energy supply requires a long construction period and a lot of investment capital. Total estimated power and energy demand of the whole economy is known to have considerable relationship with macroeconomics factors. This study reviews the Kalman filter technique and abnormal time series analysis technique which is useful in analyzing energy and macroeconomics data taking the form of pre-tallied time series data. Based on these, power demand and energy demand are estimated using real data and the most reliable technique, and long-term forecast of power and energy demand is tried up to year 2015 based on the forecasted values. It should be noted that power and energy demand of Korea shows the structurally-changing behavior based on the present while the forecast based on past data involves an assumption naturally that the trend continues from the past to the present. 15 refs., 8 figs., 15 tabs.

  16. Ethanol Demand in United States Gasoline Production

    Energy Technology Data Exchange (ETDEWEB)

    Hadder, G.R.

    1998-11-24

    The Oak Ridge National Laboratory (OWL) Refinery Yield Model (RYM) has been used to estimate the demand for ethanol in U.S. gasoline production in year 2010. Study cases examine ethanol demand with variations in world oil price, cost of competing oxygenate, ethanol value, and gasoline specifications. For combined-regions outside California summer ethanol demand is dominated by conventional gasoline (CG) because the premised share of reformulated gasoline (RFG) production is relatively low and because CG offers greater flexibility for blending high vapor pressure components like ethanol. Vapor pressure advantages disappear for winter CG, but total ethanol used in winter RFG remains low because of the low RFG production share. In California, relatively less ethanol is used in CG because the RFG production share is very high. During the winter in California, there is a significant increase in use of ethanol in RFG, as ethanol displaces lower-vapor-pressure ethers. Estimated U.S. ethanol demand is a function of the refiner value of ethanol. For example, ethanol demand for reference conditions in year 2010 is 2 billion gallons per year (BGY) at a refiner value of $1.00 per gallon (1996 dollars), and 9 BGY at a refiner value of $0.60 per gallon. Ethanol demand could be increased with higher oil prices, or by changes in gasoline specifications for oxygen content, sulfur content, emissions of volatile organic compounds (VOCS), and octane numbers.

    Full Text Available Purpose: Reducing carbon emission has been the core problem of controlling global warming and climate deterioration recently. This paper focuses on the optimal carbon taxation policy levied by countries and the impact on firms’ optimal production decisions. Design/methodology/approach: This paper uses a two-stage game theory model to analyze the impact of carbon tariff and tax. Numerical simulation is used to supplement the theoretical analysis. Findings: Results derived from the paper indicate that the demand in an unstable market is significantly affected by environmental damage level. Carbon tariff is a policy-oriented tax while the carbon tax is a market-oriented one. Comprehensive carbon taxation policy benefit developed countries and basic policy is more suitable for developing countries. Research limitations/implications: In this research, we do not consider random demand and asymmetric information, which may not well suited the reality. Originality/value: This work provides a different perspective in analyzing the impact of carbon tax and tariff. It is the first study to consider two consuming market and the strategic game between two countries. Different international status of countries considered in the paper is also a unique point.

    Determine how the Mercosur countries access, regulate, and finance costly drugs and propose joint selection and financing strategies at the subregional level. Qualitative design, using content analyses of primary and secondary sources, document reviews, interviews, focus groups, and case studies. The variables selected included: selection criteria, access, financing, and regulations in the various countries. Costly drugs were divided into those that do not alter the natural course of the disease and those with demonstrated efficacy, using the defined daily dose to compare the costs of classical treatments and those involving costly drugs. The Mercosur countries generally lack formal strategies for dealing with the demand for costly drugs, and governments and insurers wind up financing them by court order. The case studies show that there are costly drugs whose efficacy has not been established but that nonetheless generate demand. The fragmentation of procurement, international commitments with regard to intellectual property, and low negotiating power exponentially increase the price of costly drugs, putting health system finances in jeopardy. Costly drugs must be regulated and rationally selected so that only those that substantively benefit people are accepted. To finance the drugs so selected, common country strategies are needed that include such options as flexible in trade agreements, the creation of national resource funds, or joint procurement by countries to enhance their negotiating power.

  19. Estimating potential demand and supply of dengue vaccine in Brazil.

    2011-07-01

    Dengue is endemic in Brazil. Several dengue vaccine candidates, including one at the Butantan Institute in Sao Paulo, are being evaluated in clinical trials and may be licensed in several years. This study estimates the potential doses of dengue vaccine needed in Brazil under different scenarios in the first 5 years after vaccine introduction. Estimates were based on 2015-2022 country population projections. An estimated country population of 200-209 million with an annual 3.3-3.5 million cohort in the 12 to 23 month age group was included in the analysis. Computations were made for vaccines requiring one, two and three doses. A total of 7.8-62.9 million doses would be needed for only routine vaccination of 12-23 months cohort in first five years with different vaccination schedules. A combination of country-wide routine 12-23 month-old vaccination plus catch-up vaccination of individuals up to 40 years age is an appropriate strategy to control dengue. For this combination strategy, 129-425 million doses would be needed in the first five years after introduction. If vaccination is not provided to areas with low incidence of dengue, an estimated 108-360 million doses would be needed. This study provides a range of vaccine uptake estimates under different scenarios based on disease epidemiology. Actual demand and uptake will depend on the country vaccine introduction policy and strategies, vaccine supply capacity, cost, and vaccine profile. We consider one option based on the availability of vaccine from different sources. A more advanced vaccine uptake model based on estimates of vaccine impact under various scenarios should be developed.

    By mid-century, in the southern Mediterranean countries, levies probably reach the limit level of renewable water resources. Algeria is one of the poorest countries in renewable water resources, with an annual storage capacity of 14.6 million m3 in the Mediterranean coastal watersheds, representing 7% of the land area and accounts for 90 % of total surface runoff of the country. In this paper, we assess water demand to meet the needs of water users in Constantine province. The latter is located in the Kébir-Rhumel Mediterranean basin under semi-arid climate with relatively high growth rate of population, agricultural and industrial activities. Using Water Evaluation And Planning system (WEAP), we built a model for managing water demand of Constantine province. A business as usual and five scenarii of «water demand " were calculated by WEAP model to simulate the uncertainties over the period of 20 years (2008-2027) : (1) Population growth, (2) increase in irrigated crop lands, (3) decrease in basic drinking water consumption, (4) decrease in basic irrigation water consumption and (5) increase in basic industrial water consumption. The results showed that scenario 3 is the best alternative scenario and the most efficient by reducing drinking water demand for about 12 Mm3 in 20 years, and thus preserve reaching the limits of water resources potentialities.

For car drivers and car passengers, elasticities increase with the length of the journey, whereas the opposite is true for rail, bus, and air passengers......In Europe, approximately 50% of all passenger kilometres come from trips beyond 100 km according to matrices developed in the TRANSTOOLS project. This accounts for an even larger share of CO2 emissions due to a higher modal share of air transport. Therefore long-distance trips are increasingly...... relevant from a political and environmental point of view.

  5. Energy demand and mix for global welfare and stable ecosystems

    Energy Technology Data Exchange (ETDEWEB)

    Jess, A.; Kern, C.; Kaiser, P.

    2012-07-01

    Social indicators show that an annual energy consumption of 2 tonnes of oil equivalent per capita (toe pc) should be enough to ensure a sufficient global average level of welfare and happiness. Hence, rich countries with currently up to 8 toe pc should reduce and poor should legitimately increase their energy demand until 2 toe pc are reached. At today's global energy mix with 80% fossil fuels, even this optimistic scenario will inevitably lead to a conflict between welfare and stable ecosystems. The population will be 9 billion by 2050 and the ecological footprint would rise from today 1.5 to 2 planet Earths. The only option to reach the desired footprint of one planet Earth is a complete shift from fossil fuels to renewables. (orig.)

  6. An Assessment of Global Electric-Sector Water Demands to 2100 under the Latest Scenarios

    Ando, N.; Yoshikawa, S.; Kanae, S.

    2016-12-01

    Electricity demands are likely to continue growing in the coming decades, due to population and economy growth. The electric growth could lead water demands to increase because some kinds of power generation methods such as thermal power generation require large amount of water. Many countries still rely on thermal power generation. Thus, we are concerned that electricity generation could be a big factor to accelerate water scarcity. In this study, to assess the electric-sector impacts on water demands, we estimated future electric-sector water withdrawal and consumption in 17 regions from 2010 to 2100. The water withdrawal and consumption are calculated by using electricity generation and water demand intensities. The data set of future electricity generation is derived by the Asia-Pacific Integrated Model. This model applied the latest scenarios for global climate change studies, the socio-economic scenario (SSPs) and the radiative forcing scenario (RCPs). We used the water demands intensity data set of Macknick et al. (2012). Water demand intensities for power plants considerably varies by power plant cooling systems. Therefore, we constructed cooling system share scenarios. Our results indicated that by 2100, the water withdrawal and consumption in current developing countries increased and caught up with that in current developed countries. We found that socio-economic scenarios (SSPs) has large impacts on the water withdrawal and consumption. Sustainable society (SSP1) and conventional development society (SSP5) have higher economic growth than fragmentation society (SSP3). The sustainable society needs smaller amount of the water withdrawal and consumption compared with fragmentation society. In contrast, the conventional development society needs larger amount of the water withdrawal and consumption compared with fragmentation society. Therefore, higher economic growth did not always lead less electric-sector water withdrawal and consumption. A shift of

    Micronutrient deficiencies create a vicious circle of malnutrition, poverty, and economic dependency that we must strive to break. Golden Rice offers a sustainable solution to reduce the prevalence of vitamin A deficiency-related diseases and mortality, a problem that affects the health of millions of children in all developing countries. The technology is based on the reconstitution of the carotenoid biosynthetic pathway by addition of 2 transgenes. The outcome of this high-tech approach will be provided to end users as nutrient-dense rice varieties that are agronomically identical to their own, locally adapted varieties. This intervention has the potential to reach remote rural populations without access to fortification and supplementation programs. As part of our delivery strategy, we are partnering with government and nongovernment, national and international agricultural institutions to navigate through cumbersome and expensive regulatory regimes that affect the release of genetically modified crops, and to create local demand for the biofortified rice varieties.

  8. Forecasting Ontario's blood supply and demand.

    2012-02-01

    Given an aging population that requires increased medical care, an increasing number of deferrals from the donor pool, and a growing immigrant population that typically has lower donation rates, the purpose of this article is to forecast Ontario's blood supply and demand. We calculate age- and sex-specific donation and demand rates for blood supply based on 2008 data and project demand between 2008 and 2036 based on these rates and using population data from the Ontario Ministry of Finance. Results indicate that blood demand will outpace supply as early as 2012. For instance, while the total number of donations made by older cohorts is expected to increase in the coming years, the number of red blood cell (RBC) transfusions in the 70+ age group is forecasted grow from approximately 53% of all RBC transfusions in 2008 (209,515) in 2008 to 68% (546,996) by 2036. A series of alternate scenarios, including projections based on a 2% increase in supply per year and increased use of apheresis technology, delays supply shortfalls, but does not eliminate them without active management and/or multiple methods to increase supply and decrease demand. Predictions show that demand for blood products will outpace supply in the near future given current age- and sex-specific supply and demand rates. However, we note that the careful management of the blood supply by Canadian Blood Services, along with new medical techniques and the recruitment of new donors to the system, will remove future concerns. © 2012 American Association of Blood Banks.

    This guide summarizes demand response measures that can be implemented in refrigerated warehouses. In an appendix, it also addresses related energy efficiency opportunities. Reducing overall grid demand during peak periods and energy consumption has benefits for facility operators, grid operators, utility companies, and society. State wide demand response potential for the refrigerated warehouse sector in California is estimated to be over 22.1 Megawatts. Two categories of demand response strategies are described in this guide: load shifting and load shedding. Load shifting can be accomplished via pre-cooling, capacity limiting, and battery charger load management. Load shedding can be achieved by lighting reduction, demand defrost and defrost termination, infiltration reduction, and shutting down miscellaneous equipment. Estimation of the costs and benefits of demand response participation yields simple payback periods of 2-4 years. To improve demand response performance, it’s suggested to install air curtains and another form of infiltration barrier, such as a rollup door, for the passageways. Further modifications to increase efficiency of the refrigeration unit are also analyzed. A larger condenser can maintain the minimum saturated condensing temperature (SCT) for more hours of the day. Lowering the SCT reduces the compressor lift, which results in an overall increase in refrigeration system capacity and energy efficiency. Another way of saving energy in refrigerated warehouses is eliminating the use of under-floor resistance heaters. A more energy efficient alternative to resistance heaters is to utilize the heat that is being rejected from the condenser through a heat exchanger. These energy efficiency measures improve efficiency either by reducing the required electric energy input for the refrigeration system, by helping to curtail the refrigeration load on the system, or by reducing both the load and required energy input.

  10. Wireless Mesh Network Routing Under Uncertain Demands

    Science.gov (United States)

    Wellons, Jonathan; Dai, Liang; Chang, Bin; Xue, Yuan

    Traffic routing plays a critical role in determining the performance of a wireless mesh network. Recent research results usually fall into two ends of the spectrum. On one end are the heuristic routing algorithms, which are highly adaptive to the dynamic environments of wireless networks yet lack the analytical properties of how well the network performs globally. On the other end are the optimal routing algorithms that are derived from the optimization problem formulation of mesh network routing. They can usually claim analytical properties such as resource use optimality and throughput fairness. However, traffic demand is usually implicitly assumed as static and known a priori in these problem formulations. In contrast, recent studies of wireless network traces show that the traffic demand, even being aggregated at access points, is highly dynamic and hard to estimate. Thus, to apply the optimization-based routing solution in practice, one must take into account the dynamic and uncertain nature of wireless traffic demand. There are two basic approaches to address the traffic uncertainty in optimal mesh network routing (1) predictive routing that infers the traffic demand with maximum possibility based in its history and optimizes the routing strategy based on the predicted traffic demand and (2) oblivious routing that considers all the possible traffic demands and selects the routing strategy where the worst-case network performance could be optimized. This chapter provides an overview of the optimal routing strategies for wireless mesh networks with a focus on the above two strategies that explicitly consider the traffic uncertainty. It also identifies the key factors that affect the performance of each routing strategy and provides guidelines towards the strategy selection in mesh network routing under uncertain traffic demands.

    Since Lesotho was reached relatively late by the HIV/AIDS epidemic, the reported number of AIDS cases remains relatively low. Levels of awareness about the disease also remain low. With its high level of migrant labor, however, and very unequal gender relations, Lesotho has conditions which are highly conducive to the development of a major epidemic. The increasing incidence and prevalence of sexually transmitted diseases affirm the existence of high risk of HIV transmission in the country. By the end of 1995, 936 AIDS cases had been reported in Lesotho, including 68 pediatric cases. The head of the government's disease control division instead estimates that more than 4400 AIDS-related deaths had already occurred by the end of 1995 in a total population of a little more than 2 million. Women are dying at a 54.5:45.5 ratio to men, with female incidence being particularly high in the 20-39 year old age group. Having sex with multiple sex partners is the main risk factor for HIV transmission among adults in Lesotho. The most common presenting symptoms are described and the early stage impact of the epidemic discussed.

    Objectives of this study are to analyse the role of the land use sectors of Tanzania (especially forestry) on mitigation of greenhouse gases. Specific emphasis is placed on the relationship between forestry and energy supply from biomass, as well as other forestry products. This is a follow up study on an earlier effort which worked on mitigation options in the country without and in-depth analysis of the forestry and land use sectors. Analysis of the mitigation scenario has been based on Comprehensive Mitigation Analysis (COMAP). This study has analysed the forestry and land use sector behaviour on the basis of the current policies on land and environment. Furthermore three scenarios have been developed on the basis of what is expected to happen in the sectors, the worse scenario being a catastrophic one where if things takes the business as usual trend then the forest resources will easily be depleted. The TFAP scenario takes into account the implementation of the current plans as scheduled while the mitigation scenario takes into account the GHG mitigation in the implementation of the plans. A Comprehensive Mitigation Analysis Process (COMAP) has been used to analyse the GHG and cost implications of the various programmes under the mitigation scenario. (au) 30 refs.

    Science.gov (United States)

    Hilsum, L

    1988-10-01

    One of Africa's most rural and densely populated countries, Burundi is a landlocked nation in Central Africa. The 4.9 million people are 85% Hutus, agricultural people of Bantu origin. However, the Hutus are excluded from power by the minority Tutsis, and the 2 groups have engaged in violent conflict. After a military coup in 1987, a new president, Major Pierre Buyoya, was installed, but restrictions on the Hutus continue. The major difference in Burundi has been a relaxation of restrictions on the Catholic church, which were severe under the former President Bagaza. Most Hutus are Catholic, with a minority of Muslims. For the peasant farmer, faced with diminishing arable land and reliance on 1 export crop (coffee), life is becoming more difficult. An expansion of sugar production was planned to reduce reliance on coffee, although the government has a rather ambivalent approach to development. While promoting private sector development with the help of the World Bank and the U.S. government, the Burundi government maintains a rigid 1-party system with strict control over the lives of the people. Infant mortality stands at 196/1,000 live births and life expectancy is low--43 years for women and 40 years for men. The literacy rate is low (39% for men, 15% for women), and the GNP per capita is low ($230). Most land is used for subsistence crops such as cassava, bananas, sweet potatoes, maize, pulses, and sorghum.

    2013-12-01

    Full Text Available The global organic market is increasing constantly, organic sales reaching over USD 5 billion per year. Organic Monitor estimates that international sales amounted to about USD 38.6 billion in 2006, more than the double of USD 18 billion in 2000. The organic demand is concentrated in North America and Europe, these two regions comprising 97% of the global revenues. The European organic food and beverage market is the largest and most complex in the world, evaluated at USD 20 billion in 2006. Many European countries offer grants to organic farms to support organic production. This production-oriented strategy will have guaranteed success if the market structures and the marketing channels will be able to face the rapidly increasing demand and if the sellers adapt their products, sales channels and prices to the consumers’ demand.

    Electricity has been the foundation of economic growth, and constitutes one of the vital infra-structural inputs in socio-economic development. The world faces a surge in demand for electricity that is driven by such powerful forces as population growth, extensive urbanization, industrialization, and the rise in the standard of living. This paper attempts to ascertain whether there is a systematic relationship between electricity consumption and economic growth. To this end, we use a large set of data that spans 88 countries during the period, 1975-2004. A statistically significant inverted-U-shaped relationship between per-capita consumption of electricity and per-capita income is detected. Nevertheless, by using a purchasing power parity that is much higher than the per-capita income of all the countries in the world, the level of per-capita income is estimated at the peak point of per-capita electricity consumption to be $61,379 in 2000 constant international dollars. Moreover, we segment the sample into Organization for Economic Cooperation and Development (OECD) countries and non-OECD countries, and separately analyze the developed and developing countries. The separate estimation shows that even though the peak income is higher than the average per-capita income, a statistically significant inverted-U-shaped relationship is found in OECD and developed countries but not in non-OECD and developing countries.

    Full Text Available The author focuses on the money endogeneity in the context of common monetary policy implementation in the euro area. The empirical analysis shows money demand function instability during the financial crisis. The instability is described by decrease in credit money creation and money velocity changes. The cointegration tests identifed long-run positive relationship between monetary aggregates and economic activity. Concurrently, the economic activity is treated to be weakly exogenous in the model.The conclusions are discussed with Postkeynesians’ assumption, that central banks cannot fix the stock of money in a country. The causality is directed from economic activity to money demand.

The trend is strong, almost one % point higher take up per cohort, and robust across demographic groups. These trends in behavior...... are mirrored in attitudes toward benefit uptake in a broad set of countries, including Sweden. Younger generations have a more relaxed attitude toward claiming public benefits. Our findings indicate that younger generations demand more from the welfare state, and our behavioral data from Sweden quantify...

    Full Text Available The study of forecasting identifies the urgent need for special attention in evolving effective energy policies to alleviate an energy famine in the near future. Since power demand is increasing day by day in entire world and it is also one of the fundamental infrastructure input for the development, its prospects and availability sets significant constraints on the socio-economic growth of every person as well as every country. A care full long-term power plan is imperative for the development of power sector. This need assumes more importance in the state of Uttar Pradesh where the demand for electrical energy is growing at a rapid pace. This study analyses the requirement of electricity with respect to the future population for the major forms of energy in the Lucknow city in Uttar Pradesh state of India. A model consisting of significant key energy indicators have been used for the estimation. Model wherever required refined in the second stage to remove the effect of auto-correlation. The accuracy of the model has been checked using standard statistical techniques and validated against the past data by testing for ‘expost’ forecast accuracy.

  1. Price and Income Elasticities of Fuel Demand in Kosova

    Full Text Available Gasoline and diesel are the main sources of fuel required for modern life and transportation, and the adjustment of gasoline and diesel prices has become a major public issue. The drastic fluctuations in recent international oil prices have affected retail gasoline and diesel prices also in the Western Balkan countries and prompted public opinion to question the pricing behaviors of oil companies. Kosova, in the period of 17 years, has gone from a post-conflict  environment  into a state which is considered to be under transition. It has passed the reconstruction period by orienting itself toward the economic development  and European Integrations.  Price and income elasticities of gasoline demand show whether the price policy, pursued by the Kosova government, can decrease the high gasoline consumption sufficiently or not. The high deficit of the current account of balance of payments is also a concern for the Kosova’s economy; which is estimated up to 17.3% of the GDP after the foreign intervention.   The deficit of current account is being considered is related to the energy dependency. Therefore, in order to overcome such problems, control over the gasoline demand is needed to control the deficit of current accounts.Keywords:  oil price, economic development, imports, trade deficit.

    1998-07-01

    We seek to develop means of intervention in Enterprises that will enable them to react in an effective, sustainable and timely fashion to changes in the ways that markets and demand are organized; that is, to act strategically. We take an enterprise to be some entity that seeks to provide its clients with services that they value while maintaining its ability to do so in the face of changes in the demands of its clients and in the resources at its disposal. The services that clients value form around what the organization of their demands lack. The concept of strategy therefore rests on critically evaluating the ontology and semantics of the Enterprise in relation to these holes in demand organization. We access ontology and semantics by constructing and manipulating hypothetical, first-order, mathematical models of the Enterprise's services and of its value-adding processes. Because an enterprise is an anticipatory system, its semantic domain must include representations of the enterprise's model of itself and of the market and demand organizations within which it competes. First-order (set) theory provides adequate expressive power here, but alternative, higher order, mathematical frameworks, such as Dubois' hyperincursion, provide inadequate power, particularly in relation to the analysis of the properties of emergence. Knowing exactly why and where this mathematical lack manifests in the analysis process enables effective collaboration between systems analysts and psychoanalysts, and suggest directions for mathematical research.

    2015-10-01

    A rainwater harvesting system (RHS) was designed for a waste treatment facility located near the town of Mirandela (northern Portugal), to be used in the washing of vehicles and other equipment, the cleaning of outside concrete or asphalt floors, and the watering of green areas. Water tank volumes representing 100% efficiency (Vr) were calculated by the Ripple method with different results depending on two consumption scenarios adopted for irrigation. The RHS design was based on a precipitation record spanning a rather long period (3 decades). The calculated storage capacities fulfilled the water demand even when prolonged droughts occurred during that timeframe. However, because the drought events have been rather scarce the Vr values were considered oversized and replaced by optimal volumes. Notwithstanding the new volumes were solely half of the original Vr values, the projected RHS efficiency remained very high (around 90%) while the probability of system failure (efficiencyrainwater harvesting, where water availability (Vw) largely exceeds water demand (Cw), that is to say where demand fractions (Cw/Vw) are very low. Based on the results of a literature review covering an ample geographic distribution and describing a very large number of demand fraction scenarios, a Cw/Vw=0.8 was defined as the threshold to generally distinguish the low from the high demanding RHS applications.

    2009-07-15

    This report for the Swiss Federal Office of Energy (SFOE) by the University of Geneva takes a look at the price elasticity of motor fuel demand in Switzerland. Macro-economic data on petrol and diesel consumption is used to calculate short and long-term price elasticity. Various factors that have an influence on prices are discussed. Data for the period 1970 - 2008 is used. A method developed by Engle and Granger is used to examine short and long-term developments in this area. A large number of variables are used in mathematical models to explain price developments. The methods used are described and the results are presented in tabular form. Various external effects such the oil-price shocks and price developments in neighbouring countries are examined.

  6. Measuring the price responsiveness of gasoline demand: economic shape restrictions and nonparametric demand estimation

    2011-01-01

    This paper develops a new method for estimating a demand function and the welfare consequences of price changes. The method is applied to gasoline demand in the U.S. and is applicable to other goods. The method uses shape restrictions derived from economic theory to improve the precision of a nonparametric estimate of the demand function. Using data from the U.S. National Household Travel Survey, we show that the restrictions are consistent with the data on gasoline demand and remove the anom...

    2003-01-01

    This paper addresses the problem of handling the uncertainty of demand in aone-supplier-one-retailer supply chain system. Demand variation often makes the real productiondifferent from what is originally planned, causing a deviation cost from the production plan. Assumethe market demand is sensitive to the retail price in a nonlinear form, we show how to effectivelyhandle the demand uncertainty in a supply chain, both for the case of centralized-decision-makingsystem and the case of decentralized-decision-making system with perfect coordination.

  8. Cognitive task demands, self-control demands and the mental well-being of office workers.

    Bridger, Robert S; Brasher, Kate

    2011-09-01

    The cognitive task demands of office workers and the self-control demands of their work roles were measured in a sample of 196 employees in two different office layouts using a self-report questionnaire, which was circulated electronically. Multiple linear regression analysis revealed that both factors were associated with mental well-being, but not with physical well-being, while controlling for exposure to psychosocial stressors. The interaction between cognitive task demands and self-control demands had the strongest association with mental well-being, suggesting that the deleterious effect of one was greater when the other was present. An exploratory analysis revealed that the association was stronger for employees working in a large open-plan office than for those working in smaller offices with more privacy. Frustration of work goals was the cognitive task demand having the strongest negative impact on mental well-being. Methodological limitations and scale psychometrics (particularly the use of the NASA Task Load Index) are discussed. STATEMENT OF RELEVANCE: Modern office work has high mental demands and low physical demands and there is a need to design offices to prevent adverse psychological reactions. It is shown that cognitive task demands interact with self-control demands to degrade mental well-being. The association was stronger in an open-plan office.

    Unlike potential tangible positive reinforcers, which are typically identified for inclusion in functional analyses empirically using preference assessments, demands are most often selected arbitrarily or based on caregiver report. The present study evaluated the use of a demand assessment with 12 participants who exhibited escape-maintained problem behavior. Participants were exposed to 10 demands, with aversiveness measured by average latency to the first instance of problem behavior. In subsequent functional analyses, results of a demand condition that included the demand with the shortest latency to problem behavior resulted in identification of an escape function for 11 of the participants. In contrast, a demand condition that included the demand with the longest latency resulted in identification of an escape function for only 5 participants. The implication of these findings is that for the remaining 7 participants, selection of the demand for the functional analysis without using the results of the demand assessment could have produced a false-negative finding. © 2016 Society for the Experimental Analysis of Behavior.

    Full Text Available This article was written in order to provide an overview regarding the differences and similarities regarding two congruent, yet different concepts: country brand and country image. The geopolitical context and, implicitly, the current global context require a redefinition – or a more complex circumscription – of the “country image” and “country branding” concepts. In this paper, the author aimed to highlight the characteristics and particularities of the approached concepts in order to shape a framework of the context within these two operate; a brief analysis of the literature is presented, trying to emphasize the slight difference between the approached concepts

    Raquel Rangel de Meireles Guimarães

    2013-12-01

    Full Text Available In regard to the development and reform of higher education (HE, recent and projected evidence suggest that enrollment growth is likely to be slower than it is at present (or even negative as a result of ageing populations. The case of the BRIC countries is particularly interesting for the study of the impact of demographic changes on HE because these countries show considerable diversity regarding their demographic transition. This paper explores how demographic changes are likely to affect the demand for higher education in BRIC countries. I argue that these countries are now facing a great expansion of enrollment but, given declining fertility levels, diversification of the HE clientele will become a common strategy. But diversification of the student population will place a new and complex set of demands on HE institutions, and equity in higher education in the near future will depend on how HE systems are structured in these countries.

  12. Utilization rates of knee-arthroplasty in OECD countries.

    2015-10-01

    The number of knee arthroplasties and the prevalence of obesity are increasing exponentially. To date there have been no published reviews on utilization rates of knee arthroplasty in OECD countries. We analysed economic, medical and population data relating to knee arthroplasty surgeries performed in OECD countries. Gross domestic product (GDP), health expenditures, obesity prevalence, knee arthroplasty utilization rates and growth in knee arthroplasty rates per 100,000 population were assessed for total population, for patients aged 65 years and over, and patients aged 64 years and younger. Obesity prevalence and utilization of knee arthroplasty have increased significantly in the past. The mean utilization rate of knee arthroplasty was 150 (22-235) cases per 100,000 total population in 2011. The strongest annual increase (7%) occurred in patients 64 years and under. Differences between individual countries can be explained by economic and medical patterns, with countries with higher medical expenditures and obesity prevalence having significantly higher utilization rates. Countries with lower utilization rates have significantly higher growth in utilization rates. The future demand for knee prostheses will increase x-fold by 2030, with exact rates dependant upon economic, social and medical factors. We observed a 10-fold variation in the utilization of knee arthroplasty among OECD countries. A significant and strong correlation of GDP, health expenditures and obesity prevalence with utilization of knee arthroplasty was found. Patients aged 64 years and younger show a two-fold higher growth rate in knee arthroplasty compared to the older population. This trend could result in a four-fold demand for knee arthroplasty in OECD countries by 2030. Copyright © 2015 Osteoarthritis Research Society International. Published by Elsevier Ltd.

    The eleventh Energy Modeling Forum (EMF) working group met four times over the 1989--90 period to compare alternative perspectives on international oil supplies and demands through 2010 and to discuss how alternative supply and demand trends influence the world`s dependence upon Middle Eastern oil. Proprietors of eleven economic models of the world oil market used their respective models to simulate a dozen scenarios using standardized assumptions. From its inception, the study was not designed to focus on the short-run impacts of disruptions on oil markets. Nor did the working group attempt to provide a forecast or just a single view of the likely future path for oil prices. The model results guided the group`s thinking about many important longer-run market relationships and helped to identify differences of opinion about future oil supplies, demands, and dependence.

    1978-01-01

    Demand equations for general-practitioner and internist visits were estimated from 1970 CHAS-NORC survey data on health-service utilization and expenditure. Because a large proportion of respondents reported zero visits, observations were grouped according to cross-classified independent variables and regression analyses were performed using group means as data. The results showed significant differences between demand equations for general-practitioner visits and those for internist visits. Of potential importance was an apparent substitution of internists for general practitioners as ability to pay (income or insurance coverage) increased. Own-price elasticities were low for both general practitioners and internists but were even lower for the latter (0.1 to 0.02) than the former (0.2 to 0.3). The demand for services of the two specialties also differed with respect to disability days, age, sex, residence, and race. PMID:738894

    The objectives of this scoping study were to develop and test control software and wireless hardware that could enable closed-loop, zone-temperature-based demand response in buildings that have either pneumatic controls or legacy digital controls that cannot be used as part of a demand response automation system. We designed a SOAP client that is compatible with the Demand Response Automation Server (DRAS) being used by the IOUs in California for their CPP program, design the DR control software, investigated the use of cellular routers for connecting to the DRAS, and tested the wireless DR system with an emulator running a calibrated model of a working building. The results show that the wireless DR system can shed approximately 1.5 Watts per design CFM on the design day in a hot, inland climate in California while keeping temperatures within the limits of ASHRAE Standard 55: Thermal Environmental Conditions for Human Occupancy.

    2013-02-01

    Full Text Available A routing protocol is used to facilitate communication in ad hoc network. The primary goal of such a routing protocol is to provide an efficient and reliable path between a pair of nodes. The routing protocols for ad hoc network can be categorized into three categories: table driven, on demand and hybrid routing. The table driven and hybrid routing strategies require periodic exchange of hello messages between nodes of the ad hoc network and thus have high processing and bandwidth requirements. On the other hand on demand routing strategy creates routes when required and hence is very much suitable for ad hoc network. This paper therefore examines the performance of three on demand routing protocols at application layer using QualNet-5.01 simulator.

    Full Text Available Abstract Developing countries can generate effective solutions for today’s global health challenges. This paper reviews relevant literature to construct the case for international cooperation, and in particular, developed-developing country partnerships. Standard database and web-based searches were conducted for publications in English between 1990 and 2010. Studies containing full or partial data relating to international cooperation between developed and developing countries were retained for further analysis. Of 227 articles retained through initial screening, 65 were included in the final analysis. The results were two-fold: some articles pointed to intangible benefits accrued by developed country partners, but the majority of information pointed to developing country innovations that can potentially inform health systems in developed countries. This information spanned all six WHO health system components. Ten key health areas where developed countries have the most to learn from the developing world were identified and include, rural health service delivery; skills substitution; decentralisation of management; creative problem-solving; education in communicable disease control; innovation in mobile phone use; low technology simulation training; local product manufacture; health financing; and social entrepreneurship. While there are no guarantees that innovations from developing country experiences can effectively transfer to developed countries, combined developed-developing country learning processes can potentially generate effective solutions for global health systems.

    1994-01-01

    This paper reviews Space Network (SN) demand forecasting experience over the past 16 years and describes methods used in the forecasts. The paper focuses on the Single Access (SA) service, the most sought-after resource in the Space Network. Of the ten years of actual demand data available, only the last five years (1989 to 1993) were considered predictive due to the extensive impact of the Challenger accident of 1986. NASA's Space Network provides tracking and communications services to user spacecraft such as the Shuttle and the Hubble Space Telescope. Forecasting the customer requirements is essential to planning network resources and to establishing service commitments to future customers. The lead time to procure Tracking and Data Relay Satellites (TDRS's) requires demand forecasts ten years in the future a planning horizon beyond the funding commitments for missions to be supported. The long range forecasts are shown to have had a bias toward underestimation in the 1991 -1992 period. The trend of underestimation can be expected to be replaced by overestimation for a number of years starting with 1998. At that time demand from new missions slated for launch will be larger than the demand from ongoing missions, making the potential for delay the dominant factor. If the new missions appear as scheduled, the forecasts are likely to be moderately underestimated. The SN commitment to meet the negotiated customer's requirements calls for conservatism in the forecasting. Modification of the forecasting procedure to account for a delay bias is, therefore, not advised. Fine tuning the mission model to more accurately reflect the current actual demand is recommended as it may marginally improve the first year forecasting.

    This document summarizes a research effort on demand controlled ventilation and classroom ventilation. The research on demand controlled ventilation included field studies and building energy modeling. Major findings included: ? The single-location carbon dioxide sensors widely used for demand controlled ventilation frequently have large errors and will fail to effectively control ventilation rates (VRs).? Multi-location carbon dioxide measurement systems with more expensive sensors connected to multi-location sampling systems may measure carbon dioxide more accurately.? Currently-available optical people counting systems work well much of the time but have large counting errors in some situations. ? In meeting rooms, measurements of carbon dioxide at return-air grilles appear to be a better choice than wall-mounted sensors.? In California, demand controlled ventilation in general office spaces is projected to save significant energy and be cost effective only if typical VRs without demand controlled ventilation are very high relative to VRs in codes. Based on the research, several recommendations were developed for demand controlled ventilation specifications in the California Title 24 Building Energy Efficiency Standards.The research on classroom ventilation collected data over two years on California elementary school classrooms to investigate associations between VRs and student illness absence (IA). Major findings included: ? Median classroom VRs in all studied climate zones were below the California guideline, and 40percent lower in portable than permanent buildings.? Overall, one additional L/s per person of VR was associated with 1.6percent less IA. ? Increasing average VRs in California K-12 classrooms from the current average to the required level is estimated to decrease IA by 3.4percent, increasing State attendance-based funding to school districts by $33M, with $6.2 M in increased energy costs. Further VR increases would provide additional benefits

    Quarterly data for Israel are used to compare and contrast three dynamic econometric methodologies for estimating the demand for electricity by households and industrial companies. These are the Dynamic Regression Model and two approaches to cointegration (OLS and Maximum Likelihood). Since we find evidence of seasonal unit roots in the data we also test for seasonal cointegration. We find that the scale elasticities are similar in all three approaches but the OLS price elasticities are considerably lower. Moreover, OLS suggests non-cointegration. The paper concludes by stochastically simulating the DRMs to calculate upside-risk in electricity demand. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam. All rights reserved.)

  13. Entry Regulation under Asymmetric Information about Demand

    Directory of Open Access Journals (Sweden)

    Paula Sarmento

    2010-01-01

    Full Text Available We investigate how an incumbent firm can use the regulatory policy about entry and the informational advantage to protect his market position. This question is studied through the construction of a signalling game where we assume that the regulator has less information about demand than the firms. We conclude that there is a pooling equilibrium and partially separating equilibria in which entry is deterred and, if demand is high, there will be insufficient entry. The final effect on welfare depends on the tradeoff between short-run benefits (lower price and long-run losses (weaker competition.

    Full Text Available Concerning transport logistics as relation between transportand integrated approaches to logistics, some transport and logisticsspecialists consider the tenn tautological. However,transport is one of the components of logistics, along with inventories,resources, warehousing, infonnation and goods handling.Transport logistics considers wider commercial and operationalframeworks within which the flow of goods is plannedand managed. The demand for transport logistics services canbe valorised as highly qualitative, differentiated and derived.While researching transport phenomenon the implementationof models is inevitable and demand models highly desirable. Asa contribution to transport modelling this paper improves decisionmaking and planning in the transport logistics field.

    IRENA Renewable Energy Country Profiles take stock of the latest developments in the field of renewables at country level around the world. Each profile combines analysis by IRENA's specialists with the latest available country data and additional information from a wide array of sources. The resulting reports provide a brief yet comprehensive picture of the situation with regard to renewable energy, including energy supply, electrical generation and grid capacity, and access. Energy policies, targets and projects are also considered, along with each country's investment climate and endowment with renewable energy resources. The energy statistics presented here span the period from 2009 until 2012, reflecting varying timelines in the source material. Since data availability differs from country to country, wider regional comparisons are possible only for the latest year with figures available for every country included. Despite the time lag in some cases, the evident differences and disparities between countries and regions around the world remain striking. The current package of country profiles is just a starting point. The geographic scope will continue to expand, and existing profiles will be enhanced with new indicators, with the whole series maintained as a live product on the IRENA website (www.irena.org)

    This paper demonstrates that developing countries differ considerably from their developed counterparts when focus is on the nature and characteristics of short run macroeconomic fluctuations. Cycles are generally shorter, and the stylized facts of business cycles across countries are more diverse...... than those of the rather uniform industrialized countries. Supply-side models are generally superior in explaining changes in output, but a “one-size fits all” approach in formulating policy is inappropriate. Our results also illustrate the critical importance of understanding business regularities...... as a stepping-stone in the process of designing appropriate stabilization policy and macroeconomic management in developing countries....

    Full Text Available We call for the development of human biobanks in developing countries and describe several examples from low income countries which are already building their own biobanks. Developing human biobanks in developing countries requires strengthening of the research capacity to use the new technologies, as well as a shift in research investment priorities in order to reduce the inequity in international research that currently exists. A responsible approach from low-income countries to ethical issues will be another pre-requisite to the success of the ‘hypothesis-free’ research that will target the needs of the world’s poor.

    By using the ILSI network in Asia, we are holding a session focused on food safety programs in several Asian areas. In view of the external environment, it is expected to impact the global food system in the near future, including the rapid increase in food demand and in public health services due to population growth, as well as the threats to biosecurity and food safety due to the rapid globalization of the food trade. Facilitating effective information sharing holds promise for the activation of the food industry. At this session, Prof. Hwang shares the current situation of Food Safety and Sanitation Regulations in Taiwan. Dr. Liu provides a talk on the role of risk assessment in food regulatory control focused on aluminum-containing food additives in China. After the JECFA evaluation of aluminum-containing food additives in 2011, each country has carried out risk assessment based on dietary intake surveys. Ms. Chan reports on the activities of a working group on Food Standards Harmonization in ASEAN. She also explains that the ILSI Southeast Asia Region has actively supported the various ASEAN Working Groups in utilizing science to harmonize food standards. Prof. Park provides current research activities in Korea focused on the effect of climate change on food safety. Climate change is generally seen as having a negative impact on food security, particularly in developing countries. We use these four presentations as a springboard to vigorous discussion on issues related to Food Safety in Asia.

    Hungary recognises the importance of limiting greenhouse gas emissions in order to prevent or mitigate their impact on the global climate. On an international level, Hungary is not a significant carbon dioxide emitter, neither to the absolute degree nor on a per capita basis. This means that the principal reason for Hungarian participation in emission`s reduction is not perceivable international consequences but solidarity and participation in the common action of the countries of the world. Hungary is a signatory to both the Framework Convention on Climate Change and the Kyoto protocol. However, the (Hungarian) National Environmental Program also emphasises that the fulfilment of international conventions must happen at a level and pace reasonable for Hungary. The goal of this study is to investigate the potentials, costs and implementation strategies of greenhouse gas abatement in Hungary. First presented is a background of Hungary`s economy and a summary of the economic transitions in Hungary. A brief description of the Hungarian energy sector is included, with a short summary of carbon dioxide emissions, and of the Hungarian forestry sector. The following chapter is devoted to the development of baseline scenarios, from bottom-up and top-down perspectives. In the chapter on mitigation, the spectrum of energy efficiency measures in the residential and public sectors is discussed. Fifteen specific measures, whose impact is considered important, are selected and discussed in detail. The cost curves are developed for the discussed mitigation options. Then, we discuss the issues related to the implementation of energy efficiency measures in the Hungarian residential and commercial sectors. After a general background and a framework on the implementation of the energy efficiency measures in the sectors chosen, we elaborate on the practicality of these concepts. As a case study, the concept and the feasibility of carbon/energy taxes are examined. To complete the

    Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for improved sanitation in the local context is critical if facilities are to be continually used. Various approaches that attempt to change peoples' behaviours or create demand have been reviewed to identify what they are designed to address. A multi-disciplinary research team using mixed methods is re-emphasised as a comprehensive approach for assessing demand for improved sanitation in low-income informal settlements, where the sanitation situation is more challenging than in other areas. Further research involving a multi-disciplinary research team and use of mixed methods to assess sanitation demand in informal settlements is needed.

    Anatomical pathology was not popular in Taiwan a few decades ago, with a severe shortage of pathologists. However, there has been a steady increase in recent years, and now there is a threat of oversupply We evaluated supply and demand over the past three decades and compared the findings with other countries. We collected the enrollment data of pathologists and physicians from the Taiwan Society of Pathology, the Department of Health, Executive Yuan, and Taiwan Medical Association, and analyzed equivalent data from other countries. We sent questionnaires to pathology chiefs to inquire about future job vacancies. The number of pathologists has increased at an annual rate of 4.93% between 2004 and 2008, in contrast to 3.7% for all physicians. There has been a net annual increase of 12 pathologists in the past 13 years. The estimated average number of consultant posts per year was nine, which was only one-third of the average number of first-year residents (R1s). The number of pathologists/million population in Taiwan was 14.83, which was comparable to that in Japan and South Korea but much smaller than that in Canada and the United States. The ratio of pathologists to physicians in Taiwan was 0.97%, which was higher than that in Japan (0.68%) and South Korea (0.64%), but lower than in Canada (1.32%) and the United States (1.46%). On average, 1.79% of medical graduates chose pathology for their R1 training in Taiwan, which was higher than that in the United States (1.50%) and Canada (1.10-1.20%). Anatomical pathology is no longer a specialty that is facing a physician shortage in Taiwan, and there is now a relatively high pathologist/physician ratio among Asian countries. We suggest that a decrease in the number of R1s in pathology is needed to maintain a balance between supply and demand. Copyright © 2011 Formosan Medical Association & Elsevier.

    2007-11-29

    When Hurricane Katrina hit the Gulf of Mexico in 2005, the region's oil production and refining infrastructure was devastated and world energy markets were disrupted. The International Energy Agency decided in a matter of days to bring 60 million barrels of additional oil to the market. The emergency response system worked - the collective action helped to stabilise global markets. Since its founding in 1974, oil supply security has been a core mission of the IEA and the Agency has improved its mechanisms to respond to short-term oil supply disruptions. Nevertheless, numerous factors will continue to test the delicate balance of supply and demand. Oil demand growth will continue to accelerate in Asia; oil will be increasingly produced by a shrinking number of countries; and capacities in the supply chain will need to expand. These are just a few of the challenges facing an already tight market. What are the emergency response systems of IEA countries? How are their emergency structures organised? How prepared is the IEA to deal with an oil supply disruption? This publication addresses these questions. It presents another cycle of rigorous reviews of the emergency response mechanisms of IEA member countries. The goal of these reviews is to ensure that the IEA stays ready to respond effectively to oil supply disruptions. This publication also includes overviews of how China, India and countries of Southeast Asia are progressing with domestic policies to improve oil supply security, based on emergency stocks.

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Y.D. [Korea Energy Economics Institute, Euiwang (Korea, Republic of)

    1998-04-01

    Demand Function is estimated with several methods about the demand on natural gas, and analyzed per usage. Since the demand on natural gas, which has big share of heating use, has a close relationship with temperature, the inter-season trend of price and income elasticity is estimated considering temperature and economic formation. Per usage response of natural gas demand on the changes of price and income is also estimated. It was estimated that the response of gas demand on the changes of price and income occurs by the change of number of users in long term. In case of the response of unit consumption, only industrial use shows long-term response to price. Since gas price barely responds to the change of exchange rate, it seems to express the price-making mechanism that does not reflect timely the import condition such as exchange rate, etc. 16 refs., 12 figs., 13 tabs.

    2017-06-01

    In surgery, cognitive stress symptoms, including problems in concentrating, deciding, memorising, and reflecting are risks to patient safety. Recent evidence points to social stressors as antecedents of cognitive stress symptoms in surgery personnel. The current study tests whether cognitive stress symptoms are positively associated with emotional abuse, emotional- and task-related demands and resources in surgery work. Forty-eight surgery nurses from two hospitals filled out the Copenhagen Psychosocial Questionnaire in its German version. Task-related and emotional demands were positively related to cognitive stress symptoms. In a stepwise, multiple, linear regression of cognitive stress symptoms on task-related and emotional demands, emotional abuse and emotional demands were unique predictors (p < .05). Efforts to increase patient safety should address emotional abuse, emotional demands, and, therefore, communication and cooperation team climate in surgery personnel.

    In the literature, transport networks are usually treated as homogeneous networks, that is, every node has the same function, simultaneously providing and requiring resources. However, some real networks, such as power grids and supply chain networks, show a far different scenario in which nodes are classified into two categories: supply nodes provide some kinds of services, while demand nodes require them. In this paper, we propose a general transport model for these supply-demand networks, associated with a criterion to quantify their transport capacities. In a supply-demand network with heterogeneous degree distribution, its transport capacity strongly depends on the locations of supply nodes. We therefore design a simulated annealing algorithm to find the near optimal configuration of supply nodes, which remarkably enhances the transport capacity compared with a random configuration and outperforms the degree target algorithm, the betweenness target algorithm, and the greedy method. This work provides a start point for systematically analyzing and optimizing transport dynamics on supply-demand networks.
