  3. Gas-to-power market and investment incentive for enhancing generation capacity: An analysis of Ghana's electricity sector

    International Nuclear Information System (INIS)

    Fritsch, Jorik; Poudineh, Rahmatallah

    2016-01-01

    Ghana's electricity generation capacity is currently insufficient to meet demand, making power outages and load shedding common. The resulting impact is potentially devastating for the country's growth prospects. Traditionally, lack of an affordable and reliable fuel supply for power generation, coupled with ineffective institutions and an unfavourable investment climate, have resulted in Ghana's electricity sector performing poorly. In light of the 2007 discovery of natural gas reserves in Ghanaian waters, this paper examines whether domestic gas could advance the performance of the electricity sector, and if so, how. The results of our analysis show that utilization of gas reserves in Ghana's gas-to-power market is an economically superior strategy compared to an export-oriented utilization scheme. The lack of an effective regulatory framework for investment, skill shortages, and an inefficient electricity pricing structure continue to be the main constraining factors. Our analysis also considers possible approaches to modification of the electricity tariff in order to send the right signal to potential investors in generation capacity, without compromising the affordability of power supply. - Highlights: •We examine if domestic gas can improve the Ghanaian electricity sector performance. •We compare domestic gas-to-power market utilisation versus gas export. •It shows that gas-to-power market is more economical compared to gas export. •Ineffective investment regime, skill shortage and inefficient tariffs are barriers.

  4. Small distributed generation versus centralised supply: a social cost-benefit analysis in the residential and service sectors

    Gulli, Francesco

    2006-01-01

    This paper aims at measuring the social benefits of small CHP distributed generation (DG) in the residential and service sectors. We do this by comparing the social costs of decentralised and centralised supplies, simulating 'ideal' situations in which any source of allocative inefficiencies is eliminated. This comparison focuses on assessing internal and external costs. The internal costs are calculated by simulating the optimal prices of the electricity and gas inputs. The external costs are estimated by using and elaborating the results of the dissemination process of the ExternE project, one of the most recent and accurate methodologies in this field. The analysis takes into account the main sources of uncertainty about the parameter values, including uncertainty about external cost estimations. Despite these sources of uncertainty, the paper concludes that centralised supply is still preferable to small DG. In fact, the overall range of DG social competitiveness is restricted, even considering further remarkable improvements in DG electrical efficiency and investment costs. The results are particularly unfavourable for the residential sector, whereas, in the service sector, the performance of DG technologies is slightly better

  5. Internalisation of external cost in the power generation sector: Analysis with Global Multi-regional MARKAL model

    International Nuclear Information System (INIS)

    Rafaj, Peter; Kypreos, Socrates

    2007-01-01

    The Global MARKAL-Model (GMM), a multi-regional 'bottom-up' partial equilibrium model of the global energy system with endogenous technological learning, is used to address impacts of internalisation of external costs from power production. This modelling approach imposes additional charges on electricity generation, which reflect the costs of environmental and health damages from local pollutants (SO 2 , NO x ) and climate change, wastes, occupational health, risk of accidents, noise and other burdens. Technologies allowing abatement of pollutants emitted from power plants are rapidly introduced into the energy system, for example, desulphurisation, NO x removal, and CO 2 scrubbers. The modelling results indicate substantial changes in the electricity production system in favour of natural gas combined cycle, nuclear power and renewables induced by internalisation of external costs and also efficiency loss due to the use of scrubbers. Structural changes and fuel switching in the electricity sector result in significant reduction of emissions of both local pollution and CO 2 over the modelled time period. Strong decarbonisation impact of internalising local externalities suggests that ancillary benefits can be expected from policies directly addressing other issues then CO 2 mitigation. Finally, the detailed analysis of the total generation cost of different technologies points out that inclusion of external cost in the price of electricity increases competitiveness of non-fossil generation sources and fossil power plants with emission control

    Toba, Natsuko

    2007-01-01

    This paper reports an empirical investigation into the welfare impacts of the introduction of private sector participation into the Philippines electricity generation sector, by liberalizing the market for independent power producers (IPPs) during the power crisis of 1990-1993. This study uses a social cost and benefit analysis. The main benefits came from IPPs, who contributed to resolving the crisis, and promoted economic and social development. Consumers and investors were net gainers, while the government lost and there was an air pollution cost. The paper concludes that the reform with private sector participation increased social welfare

  8. Lepton sector of a fourth generation

    2010-01-01

    In extensions of the standard model with a heavy fourth generation, one important question is what makes the fourth-generation lepton sector, particularly the neutrinos, so different from the lighter three generations. We study this question in the context of models of electroweak symmetry breaking in warped extra dimensions, where the flavor hierarchy is generated by choosing the localization of the zero-mode fermions in the extra dimension. In this setup the Higgs sector is localized near the infrared brane, whereas the Majorana mass term is localized at the ultraviolet brane. As a result, light neutrinos are almost entirely Majorana particles, whereas the fourth-generation neutrino is mostly a Dirac fermion. We show that it is possible to obtain heavy fourth-generation leptons in regions of parameter space where the light neutrino masses and mixings are compatible with observation. We study the impact of these bounds, as well as the ones from lepton flavor violation, on the phenomenology of these models.

    Persistent organic pollutants (POPs) are toxic substances and so harmful for human health. Mitigation of these emissions are internationally addressed by the Convention on Long-range Transboundary Air Pollution and by the Stockholm Convention. A global insight on POPs emissions evolution is essential since they can be transported long distances, they bio-accumulate and damage the environment. The Emission Database for Global Atmospheric Research (EDGARv4) is currently updated with POPs. We have estimated the global emissions of Polychlorinated biphenyls (PCBs), Polychlorinated dibenzo-p-dioxins (PCDDs), Polychlorinated dibenzofurans (PCDFs), Polycyclic aromatic hydrocarbons (PAHs) (benzo[a]pyrene (BaP), benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF), Indeno[1,2,3-cd]pyrene (IcdP)) and Hexachlorobenzene (HCB) from fuel combustion in the power generation, residential and transport sectors. This emissions inventory has been developed by using as input to the EDGAR technology-based emissions calculation algorithm the fossil fuel consumption data from International Energy Agency (2014) and the emission factors from EMEP/EEA (2013). We provide a complete emission time series for the period 1970-2010 and discuss the trends. A comprehensive analysis of the contribution of East Asia region to the total global will be provided for each substance of the POPs group. An example is presented in Figure 1 for BaP emissions from residential sector; with emissions mainly from China, the East Asia region has a great share (32%) in the total global. We distributed the POPs emissions on gridmaps of 0.1°x0.1° resolution. Areas with high emissions in East Asia will be presented and discussed; Figure 2 shows the hot-spots in East Asia for BaP emissions from the residential sector. These emission gridmaps, used as input for the chemical transport models, contribute to the improvement of impact evaluation, which is a key element in measuring the effectiveness of mitigation

    Fossil fuel are used in power generation in oil and gas producing countries due to the resource availability. However, the growing electricity demand, the potential exports revenues associated to hydrocarbons as well as the environmental policies have to be taken into account for the definition of the electricity generation mix. Thus, the development of the power generation capacities according to the resource availability and the economic factors (demand and costs) is investigated through a modeling approach. Over the past ten years, Egypt has become an important gas producer and a strategic gas supplier for Europe. Moreover, natural gas represents around eighty percent of the Egyptian power sector mix. However, this extensive share of natural gas in power generation mix could not be sustainable in long-term due to the limited hydrocarbons' resources of Egypt. In this study, the current and future power generation situation of the country is analyzed through a dynamic linear programming model. Finally, a power generation strategy based on a gradual integration of nuclear and renewable is suggested. (authors)

    Full Text Available Globalization, deregulation and technological improvements have resulted in increase in M&A across the globe. There is enormous literature existing in the advanced economies. However, very little information is available regarding M&A in India. Various sectors have witnessed differential involvement in M&A activity indicating higher participation by some. Particularly, certain sectors such as financial services and pharmaceuticals demonstrate higher M&A activity. To emphasise differential importance of sectors in M&A activity, it is necessary to conduct a sector-wise analysis. Accordingly, this study attempts to investigate the differential representation of various sectors in M&A. Further, it explores the role played by India in the rising global M&A activity. In light of this, it specifies the factors driving consolidation in the financial sector globally.

  17. Performance measurement in transport sector analysis

    Directory of Open Access Journals (Sweden)

    M. Išoraitė

    2004-06-01

    Full Text Available The article analyses the following issues: 1. Performance measurement in literature. The performance measurement has an important role to play in the efficient and effective management of organizations. Kaplan and Johnson highlighted the failure of the financial measures to reflect changes in the competitive circumstances and strategies of modern organizations. Many authors have focused attention on how organizations can design more appropriate measurement systems. Based on literature, consultancy experience and action research, numerous processes have been developed that organizations can follow in order to design and implement systems. Many frameworks have been proposed that support these processes. The objective of such frameworks is to help organizations define a set of measures that reflect their objectives and assess their performance appropriately. 2. Transport sector performance and its impacts measuring. The purpose of transport measurement is to identify opportunities enhancing transport performance. Successful transport sector management requires a system to analyze its efficiency and effectiveness as well as plan interventions if transport sector performance needs improvement. Transport impacts must be measurable and monitorable so that the person responsible for the project intervention can decide when and how to influence them. Performance indicators provide a means to measure and monitor impacts. These indicators essentially reflect quantitative and qualitative aspects of impacts at given time and places. 3. Transport sector output and input. Transport sector inputs are the resources required to deliver transport sector outputs. Transport sector inputs are typically: human resources, particularly skilled resources (including specialists consulting inputs; technology processes such as equipment and work; and finance, both public and private. 4. Transport sector policy and institutional framework; 5. Cause – effect linkages; 6

  18. Distributed photovoltaic generation in Brazil: An economic viability analysis of small-scale photovoltaic systems in the residential and commercial sectors

    International Nuclear Information System (INIS)

    Holdermann, Claudius; Kissel, Johannes; Beigel, Jürgen

    2014-01-01

    This paper examines the economic viability of small-scale, grid-connected photovoltaics in the Brazilian residential and commercial sectors after the introduction of the net metering regulation in April 2012. This study uses the discounted cash flow method to calculate the specific investment costs that are necessary for photovoltaic systems to be economically viable for each of the 63 distribution networks in Brazil. We compare these values to the system costs that are estimated in the comprehensive study on photovoltaics that was developed by the Brazilian Association of Electric and Electronic Industries (ABINEE). In our calculation, we utilize the current electricity tariffs, including fees and taxes, which we obtained through telephone interviews and publicly available information. We obtained a second important parameter by simulating PV-systems with the program PV ⁎ Sol at the distribution company headquarters' locations. In our base case scenario that reflects the current situation, in none of the distribution networks photovoltaics is economically viable in either the commercial or residential sectors. We improved the environment for grid-connected photovoltaics in our scenarios by assuming both lower PV-system costs and a lower discount rate to determine the effect on photovoltaics viability. - Highlights: • We calculate the economic viability of photovoltaics in the residential and commercial sectors in Brazil. • The PV ⁎ Sol simulations are carried out at the headquarter locations for the 63 distribution companies. • Currently in none of the distribution networks, photovoltaics is economically viable in either the commercial or residential sectors. • We analyze how the variation of the specific investment costs and of the discount rate affects the economic viability

  19. The development of market power in the Polish power generation sector: A 10-year perspective

    Kamiński, Jacek

    2012-01-01

    The paper examines how and to which extent consolidation in the Polish power generation sector has affected the potential for market power over the last 10 years. Although this sector has been undergoing liberalisation (privatisation, introduction of TPA regulations and competition etc.), the consolidation efforts shown by Polish governments have resulted in a significant increase in concentration of both installed capacity and production. The methodology applied in this study includes typical ex-post structural and behavioural measures employed to estimate potential for market power, namely: concentration ratios (for the largest and the three largest suppliers), the Herfindahl–Hirschman Index, entropy, Supply Margin Assessment, the Residual Supply Index and the Lerner Index. Furthermore, an analysis based on the Gini coefficient was employed to obtain an insight into inequalities. The results of this study show that governmental decisions led to a significant increase in the potential to exercise market power held by key power generation companies. Of key importance was the 2007 consolidation, resulting in an increase in the HHI to 1374 (in terms of installed capacity) and 1945 (in terms of electricity production). This consolidation resulted in the creation of the first Pivotal Supplier in the Polish power generation sector in 2008. - Highlights: ► Market power analysis based on structural and behavioural indices was carried out for the Polish power sector. ► Governmental policy resulted in significant increase in concentration of both installed capacity and generation. ► Increase in the Lerner Index of brown coal-based generation and decrease of the hard coal-based one were observed.

  20. Liberalisation of the electricity sector and development of distributed generation: Germany, United Kingdom and France

    International Nuclear Information System (INIS)

    Menanteau, Ph.

    2003-01-01

    Historically, electricity systems have been made up of small local networks gradually becoming incorporated to benefit from the diversity of demand and the economies of scale in electricity generation that are possible with large interconnected systems. Today, this logic would seem to have certain limits, now that the benefits related to the size of production units appear to have been exhausted and in view of the growing difficulties in developing new transmission infrastructures. At the same time, there have been considerable improvements in the technical and economic performance of modular generating techniques, which are now enjoying significant development under the effect of electricity sector liberalization and policies to reduce greenhouse gas emissions. The aim of the present paper is to analyse the effect of electricity sector liberalization on the development of distributed generation, and more specifically to examine the conditions in which these new electricity generating technologies can be diffused in a liberalized framework. The paper looks first at how competition has affected the electricity market. This analysis is followed by an examination of the problems of integrating distributed generation into electricity systems. In the third part of the paper, three brief case studies highlight the principal differences between Germany, the United Kingdom and France in the field of distributed generation. This brief analysis reveals that the institutional framework in which distributed generation must operate and the price signals given to electricity sector actors play as big a part as traditional incentives, certificates, bidding systems or guaranteed feed-in tariffs in driving the deployment process.

    Berglund, P.; Parkes, L.; Huebsch, T.

    1992-01-01

    We consider a Calabi-Yau compactification paradigm with three light generations and an R-symmetry. From a special form of the Tian-Yau manifold, we also construct a new three-generation model with markedly different phenomenology. The complete spectrum of all light matter fields is obtained in a universal way and moreover in a physically suitable basis, allowing a straightforward analysis of all their couplings. Here we discuss all the renormalizable Yukawa couplings. This computation can equally well be repeated for all compactification models based on Calabi-Yau complete intersections in products of homogeneous spaces. (orig.)

  4. Diversity of fuel sources for electricity generation in an evolving U.S. power sector

    Science.gov (United States)

    DiLuccia, Janelle G.

    Policymakers increasingly have shown interest in options to boost the relative share of renewable or clean electricity generating sources in order to reduce negative environmental externalities from fossil fuels, guard against possible resource constraints, and capture economic advantages from developing new technologies and industries. Electric utilities and non-utility generators make decisions regarding their generation mix based on a number of different factors that may or may not align with societal goals. This paper examines the makeup of the electric power sector to determine how the type of generator and the presence (or lack) of competition in electricity markets at the state level may relate to the types of fuel sources used for generation. Using state-level electricity generation data from the U.S. Energy Information Administration from 1990 through 2010, this paper employs state and time fixed-effects regression modeling to attempt to isolate the impacts of state-level restructuring policies and the emergence of non-utility generators on states' generation from coal, from fossil fuel and from renewable sources. While the analysis has significant limitations, I do find that state-level electricity restructuring has a small but significant association with lowering electricity generation from coal specifically and fossil fuels more generally. Further research into the relationship between competition and fuel sources would aid policymakers considering legislative options to influence the generation mix.

    Turkish electricity sector has undergone significant institutional changes since 1984. The recent developments since 2001 including the setting up of a regulatory agency to undertake the regulation of the sector and increasing participation of private investors in the field of electricity generation are of special interest. This paper estimates cost functions and investigates the degree of scale economies, overinvestment, and technological progress in the Turkish electricity generation sector for the period 1984-2006 using long-run and short-run translog cost functions. Estimations were done for six groups of firms, public and private. The results indicate existence of scale economies throughout the period of analysis, hence declining long-run average costs. The paper finds empirical support for the Averch-Johnson effect until 2001, i.e., firms overinvested in an environment where there are excess returns to capital. But this effect was reduced largely after 2002. Technological progress deteriorated slightly from 1984-1993 to 1994-2001 but improved after 2002. Overall, the paper found that regulation of the market under the newly established regulating agency after 2002 was effective and there are potential gains from such regulation. (author)

  9. Generating efficiency: The power of price caps in the public and private Spanish electricity sectors

    International Nuclear Information System (INIS)

    Arocena, P.; Price, C.W.

    1999-01-01

    Economic regulation of firms with market power has placed increasing emphasis on incentive-based regulation such as price caps. The move to such regulation often coincides with a change of ownership, making it difficult to separate the incentive effects. We focus on the effect of regulation alone by analysing the imposition of price cap type regulation on both publicly and privately owned Spanish electricity generators in 1988, several years before three was any change of ownership. Our initial results indicate that the publicly owned generators are generally more efficient than the private ones, but that the effect of price caps is to increase the efficiency of private sector plants faster than those in the public sector. We introduce two novelties into the analysis: we incorporate levels of CO2 and NOx emissions; and we include declared plant availability as an output. The outcome is dependent on the choice of inputs and outputs, and we argue that our measures are more appropriate than traditional measures for a system of central despatch for generators facing environmental constraints.

The first report on situation and predictions which is updated three times a year, proposes a synthesis on the consequences of the evolution of the economic environment, on major trends noticed for the sector, and on predictable evolutions. It proposes the most recent predictions regarding natural gas consumption in France and the turnover of the gas sector. It highlights recent events for companies of the sector: takeovers, investments, restructuring, introduction of new products, and so on. It proposes a sector-based dashboard which contains all the critical figures useful to analyse the sector situation (activity determining factors, key figures for the sector and its environment). The second report (the annual one) proposes an overview of trends and competition within the gas sector. It gives an overview of some basic aspects of the activity (sector organisation, gas categories, main customer markets, gas consumption in industry), and of its determining factors, analyses the sector environment (sites connected to the natural gas network, evolution of average temperatures in France, production by chemical industry, by the food industry, and by metallurgy and oil refining, thermal production of electricity, regulatory evolution regarding supports to energy efficiency, and new opportunities). The evolution of the sector activity is analysed through its trends and indicators (turnovers, gas consumption, butane-propane deliveries, wholesale prices, regulated tariffs). The economic structure is also analysed: aspects related to the upstream part (extraction, injection of biogas, natural gas main input and output points, transport and storage, natural gas distribution), and aspects related to gas provision

  11. Photovoltaic electricity generation: Value for residential and commercial sectors

    Science.gov (United States)

    Bhattacharjee, Ujjwal

    The photovoltaic (PV) industry in the US has seen an upsurge in recent years, and PV holds great promise as a renewable technology with no greenhouse gas emissions with its use. We aim to assess the value of PV based electricity for users in the residential and commercial sectors focusing on the financial impacts it has, which may not be greatly recognized. Specifically, we pursue two goals. First, the emerging 'renewable portfolio standard (RPS)' adopted in several states in the country has been a driving force for large scale PV deployment, but financial incentives offered to PV in different RPS states differ considerably. We use life cycle cost model to estimate the cost of PV based electricity for thirty-two RPS states in the country. Results indicate that the levelized cost of PV electricity is high (40 to 60 Cents/kWh). When the contribution of the financial incentives (along with the cost of energy saved) is taken into account, the cost of PV based electricity is negative in some RPS states such as California, New Jersey, New York, while for most of the RPS states the cost of PV electricity continues to remain high. In addition, the states with negative or low cost of PV electricity have been driving the PV diffusion in the residential sector. Therefore, a need to adjust the financial incentive structure in different RPS states is recommended for homogenous development of the residential PV market in the country. Second, we assess the value of the PV in reducing the highest peak load demand in commercial buildings and hence the high value demand charge. The Time-of-Use (TOU) based electricity tariff is widely used by electric utilities in the commercial sector. Energy and peak load are two important facets of the TOU tariff regime. Tools are well established to estimate the energy contribution from a PV system (installed in a commercial building), but not power output on a short time interval. A joint conditional probability model has been developed that

    In FY96, NREL was asked to coordinate all analysis tasks so that in FY97 these tasks will be part of an integrated analysis agenda that will begin to define a 5-15 year R&D roadmap and portfolio for the DOE Hydrogen Program. The purpose of the Supporting Analysis and Assessments task at NREL is to provide this coordination and conduct specific analysis tasks. One of these tasks is to prepare the Quality Metrics (QM) for the Program as part of the overall QM effort at DOE/EERE. The Hydrogen Program one of 39 program planning units conducting QM, a process begun in FY94 to assess benefits/costs of DOE/EERE programs. The purpose of QM is to inform decisionmaking during budget formulation process by describing the expected outcomes of programs during the budget request process. QM is expected to establish first step toward merit-based budget formulation and allow DOE/EERE to get {open_quotes}most bang for its (R&D) buck.{close_quotes} In FY96. NREL coordinated a QM team that prepared a preliminary QM for the utility market sector. In the electricity supply sector, the QM analysis shows hydrogen fuel cells capturing 5% (or 22 GW) of the total market of 390 GW of new capacity additions through 2020. Hydrogen consumption in the utility sector increases from 0.009 Quads in 2005 to 0.4 Quads in 2020. Hydrogen fuel cells are projected to displace over 0.6 Quads of primary energy in 2020. In future work, NREL will assess the market for decentralized, on-site generation, develop cost credits for distributed generation benefits (such as deferral of transmission and distribution investments, uninterruptible power service), cost credits for by-products such as heat and potable water, cost credits for environmental benefits (reduction of criteria air pollutants and greenhouse gas emissions), compete different fuel cell technologies against each other for market share, and begin to address economic benefits, especially employment.

    Food waste has significant detrimental economic, environmental and social impacts. The magnitude and complexity of the global food waste problem has brought it to the forefront of the environmental agenda; however, there has been little research on the patterns and drivers of food waste generation, especially outside the household. This is partially due to weaknesses in the methodological approaches used to understand such a complex problem. This paper proposes a novel conceptual framework to identify and explain the patterns and drivers of food waste generation in the hospitality sector, with the aim of identifying food waste prevention measures. This conceptual framework integrates data collection and analysis methods from ethnography and grounded theory, complemented with concepts and tools from industrial ecology for the analysis of quantitative data. A case study of food waste generation at a hotel restaurant in Malaysia is used as an example to illustrate how this conceptual framework can be applied. The conceptual framework links the biophysical and economic flows of food provisioning and waste generation, with the social and cultural practices associated with food preparation and consumption. The case study demonstrates that food waste is intrinsically linked to the way we provision and consume food, the material and socio-cultural context of food consumption and food waste generation. Food provisioning, food consumption and food waste generation should be studied together in order to fully understand how, where and most importantly why food waste is generated. This understanding will then enable to draw detailed, case specific food waste prevention plans addressing the material and socio-economic aspects of food waste generation.

    We know from evolutionary theory that sectoral characteristics are important to innovation. This paper investigates if sectoral characteristics also are important to eco-innovation, a hitherto under-researched theme. We argue that research into possible sectoral patterns in eco-innovation is key...... 1965 to 2012, focusing on powertrain technologies. The empirical analysis is based on patent data amongst big car producers and focuses on identifying changes in two main aspects: (1) the convergence/divergence of firms’ green strategies and technologies within the automotive sector; and (2......) the contribution of alternative key green technological trajectories relative to the dominant design. Our findings indicate that the evolution of relative green patenting has followed a positive, linear growth over the last decades with increasing participation of alternative propulsion technologies and increasing...

  15. Business venture-analysis case study relating to the manufacture of gas turbines for the generation of utility electric power. Volume II. Private sector and public sector venture studies. Final report. [Use of coal gasifier with combined gas and steam system

    Increasing national attention is being directed toward the search for clean, efficient, and reliable energy-conversion systems, capable of using abundant indigenous fuels such as coal, for generation of utility electric power. A prime candidate in this area is the combined gas and steam (COGAS) system employing a high-temperature gas turbine with a steam-turbine bottoming cycle, fed by a coal gasifier. This program demonstrates the use of a logical and consistent venture-analysis methodology which could also be applied to investigate other high-technology, energy-conversion systems that have yet to reach a state of commercialization but which are of significant interest to the U.S. Government. The venture analysis was performed by using a computer to model the development, production, sales, and in-service development phases of programs necessary to introduce new gas turbines in COGAS systems. The simulations were produced in terms of estimated cash flows, rates of returns, and risks which a manufacturer would experience. Similar simulations were used to estimate public-sector benefits resulting from the lower cost of power and improved environment gained from the use of COGAS systems rather than conventional systems. The study shows that substantial social benefits could be realized and private investment would be made by the gas-turbine manufacturers if an infusion of external funds were made during key portions of the gas-turbine development program. It is shown that there is substantial precedent for such public assistance to make possible economic and environmental benefits that otherwise would not be possible. 42 references.

    Outbreaks of contagious diseases underscore the ever-looming threat of new epidemics. Compared to other disasters that inflict physical damage to infrastructure systems, epidemics can have more devastating and prolonged impacts on the population. This article investigates the interdependent economic and productivity risks resulting from epidemic-induced workforce absenteeism. In particular, we develop a dynamic input-output model capable of generating sector-disaggregated economic losses based on different magnitudes of workforce disruptions. An ex post analysis of the 2009 H1N1 pandemic in the national capital region (NCR) reveals the distribution of consequences across different economic sectors. Consequences are categorized into two metrics: (i) economic loss, which measures the magnitude of monetary losses incurred in each sector, and (ii) inoperability, which measures the normalized monetary losses incurred in each sector relative to the total economic output of that sector. For a simulated mild pandemic scenario in NCR, two distinct rankings are generated using the economic loss and inoperability metrics. Results indicate that the majority of the critical sectors ranked according to the economic loss metric comprise of sectors that contribute the most to the NCR's gross domestic product (e.g., federal government enterprises). In contrast, the majority of the critical sectors generated by the inoperability metric include sectors that are involved with epidemic management (e.g., hospitals). Hence, prioritizing sectors for recovery necessitates consideration of the balance between economic loss, inoperability, and other objectives. Although applied specifically to the NCR, the proposed methodology can be customized for other regions. © 2012 Society for Risk Analysis.

    Primarily, health sector connects two segments - medicine and public health, where medicine deals with individual patients and public health with the population health. Budget enables both the disciplines to function effectively. The Interim Constitution of Nepal, 2007 has adapted the inspiration of federalism and declared the provision of basic health care services free of cost as a fundamental right, which needs strengthening under foreseen federalism. An observational retrospective cohort study, aiming at examining the health sector budget allocation and outcome, was done. Authors gathered health budget figures (2001 to 2013) and facts published from authentic sources. Googling was done for further information. The keywords for search used were: fiscal federalism, health care, public health, health budget, health financing, external development partner, bilateral and multilateral partners and healthcare accessibility. The search was limited to English and Nepali-language report, articles and news published. Budget required to meet the population's need is still limited in Nepal. The health sector budget could not achieve even gainful results due to mismatch in policy and policy implementation despite of political commitment. Since Nepal is transforming towards federalism, an increased complexity under federated system is foreseeable, particularly in the face of changed political scenario and its players. It should have clear goals, financing policy and strict implementation plans for budget execution, task performance and achieving results as per planning. Additionally, collection of revenue, risk pooling and purchasing of services should be better integrated between central government and federated states to horn effectiveness and efficiency.

    Full Text Available The public sector in developed countries went through various forms of transformation in the twentieth century. The expansion of the public sector resulted in high levels of public spending in developed countries. The financial crisis of 2008 led to recessions in the economies of developed countries, the public debt growth, and actualized the issue of the public sector optimal size and efficiency. This study analysed the public sector efficiency in 19 developed countries. The analysis focuses on the relationship between the size of public expenditure and economic growth in the global financial crisis and the measures implemented. The aim of the research in this paper is a comparison of total and partial efficiency of the public sector in developed countries, in order to determine the characteristics of the public sector operations. The comparison covers the areas of the public sector operations in order to identify sources of inefficiency. Partial and overall efficiency of countries are analysed with different size and concept of the public sector, to determine the relationship between the public sector size, efficiency and welfare of citizens. The research results clearly indicate (unjustified state intervention in developed countries.

    Full Text Available With the rise of the environmental variable in the business environment, companies started to give greater attention to strategies and practices focused on the rational use of natural resources and minimize the environmental impacts of their business operations. Many productive sectors stood out in the reflections on production and the environment, as is the case of the sugar energy industry, which constitutes a sector with a highly demanding industrial activity of natural resources, whether as sources of inputs as depositories of waste production. Thus, the aim of this paper is a comparative analysis of environmental practices of two sugar energy plants, both from the point of view of their operational strategy and regarding the suitability of the disposal of waste generated by the industrial area. It was concluded that, although many practices adopted by businesses are analogous, one of the studied plants have distinctive environmental performance, because of the increased attention given to the implementation of environmental practices and especially the inclusion of the environmental variable in their strategies.

    In his letter dated May 7. 1999, the French Prime Minister Lionel Jospin asked Jean-Michel Charpin, Benjamin Dessus and Rene Pellat to carry out a 'study of the economic data for the whole of the nuclear sector, in particular downstream of the nuclear combustion cycle, including reprocessing'. This report had to include comparisons with other production methods for electricity and take account of environmental costs. The Prime Minister stressed in this same letter his wish to see the inquiry 'examine all of the factors forming the basis for a public decision, including intrinsic competitiveness, external factors and long-term effects, as well as the impact of different production methods upon our CO 2 gas emissions and control over the downstream part of the nuclear cycle'. Two series of questions are central to this study. The first concerns the existing nuclear facilities. In view of the inertia of a French electrical production system which is largely based upon nuclear energy and in which major investments have already been made, what room for manoeuvre remains for the public authorities and operators concerning the future of these stations? In particular: What are the economic conditions and consequences of possibly prolonging the average active life of the existing stations? What are the economic and environmental consequences of decisions concerning the continuation or stoppage of the reprocessing of irradiated fuel produced by the existing stations? The second concerns new investments likely to meet electrical demand under various scenarios. In particular: what are the technologies that may be envisaged (nuclear and non-nuclear) and in what timescale? What are the changes underway in the world that are likely to have an influence on the choices made in France? What will be the environmental consequences of these choices by the year 2050, in particular regarding greenhouse gas emissions and the quantities of transuranic elements to be stored? What will be

    This paper provides an overview of early changes in the sectoral innovation system for power generation technologies which have been triggered by the European Emission Trading Scheme (EU ETS). Based on a broad definition of the sector, our research analyses the impact of the EU ETS on the four building blocks 'knowledge and technologies', 'actors and networks', 'institutions' and 'demand' by combining two streams of literature, namely systems of innovation and environmental economics. Our analysis is based on 42 exploratory inter-views with German and European experts in the field of the EU ETS, the power sector and technological innovation. We find that the EU ETS mainly affects the rate and direction of the technological change of power generation technologies within the large-scale, coal-based power generation technological regime to which carbon capture technologies are added as a new technological trajectory. While this impact can be interpreted as defensive behaviour of incumbents, the observed changes should not be underestimated. We argue that the EU ETS' impact on corporate CO2 culture and routines may prepare the ground for the transition to a low carbon sectoral innovation system for power generation technologies. (orig.)

    Full Text Available The tertiary sector is one of the modern styles of economic systems in view of the share it occupies in the field of production as well as employment occupied share. Hence, just like other lands, the UAE, witnessed an economic structural change similar to developed and developing nations, where the tertiary industries contributed 55.4% in 2015 to total country’s income. The empirical study aimed to analyze the contribution portion of growth in the tertiary industries through using the growth accounting framework in time-series from 1990 to 2015. The empirical study found that most of the industries contributed significantly to the growth of the tertiary sector. The contribution shares of growth due to labor and capital varied among industries. The main observed results show that there was a vice versa relationship between TFP performance and the size of labor, where the TFP positively corresponded with the decline in the size of labor specifically from 2010-2015.

    Small-scale (100 kW - 5 MW) on-site distributed generation (DG) economically driven by combined heat and power (CHP) applications and, in some cases, reliability concerns will likely emerge as a common feature of commercial building energy systems in developed countries over the next two decades. In the U.S., private and public expectations for this technology are heavily influenced by forecasts published by the Energy Information Administration (EIA), most notably the Annual Energy Outlook (AEO). EIA's forecasts are typically made using the National Energy Modeling System (NEMS), which has a forecasting module that predicts the penetration of several possible commercial building DG technologies over the period 2005-2025. Annual penetration is forecast by estimating the payback period for each technology, for each of a limited number of representative building types, for each of nine regions. This process results in an AEO2004 forecast deployment of about a total 3 GW of DG electrical generating capacity by 2025, which is only 0.25% of total forecast U.S. capacity. Analyses conducted using both the AEO2003 and AEO2004 versions of NEMS changes the baseline costs and performance characteristics of DG to reflect a world without U.S. Dept. of Energy (DOE) research into several thermal DG technologies, which is then compared to a case with enhanced technology representative of the successful achievement of DOE research goals. The net difference in 2025 DG penetration is dramatic using the AEO2003 version of NEMS, but much smaller in the AEO2004 version. The significance and validity of these contradictory results are discussed, and possibilities for improving estimates of commercial U.S. DG potential are explored

  14. Internalisation of external costs in the Polish power generation sector: A partial equilibrium model

    Kudelko, Mariusz

    2006-01-01

    This paper presents a methodical framework, which is the basis for the economic analysis of the mid-term planning of development of the Polish energy system. The description of the partial equilibrium model and its results are demonstrated for different scenarios applied. The model predicts the generation, investment and pricing of mid-term decisions that refer to the Polish electricity and heat markets. The current structure of the Polish energy sector is characterised by interactions between the supply and demand sides of the energy sector. The supply side regards possibilities to deliver fuels from domestic and import sources and their conversion through transformation processes. Public power plants, public CHP plants, industry CHP plants and municipal heat plants represent the main producers of energy in Poland. Demand is characterised by the major energy consumers, i.e. industry and construction, transport, agriculture, trade and services, individual consumers and export. The relationships between the domestic electricity and heat markets are modelled taking into account external costs estimates. The volume and structure of energy production, electricity and heat prices, emissions, external costs and social welfare of different scenarios are presented. Results of the model demonstrate that the internalisation of external costs through the increase in energy prices implies significant improvement in social welfare

    Highlights: → We conduct a decomposition exercise of the South African electricity consumption. → The increase in electricity consumption was due to output and structural changes. → The increasing at a low rate electricity intensity was a decreasing factor to consumption. → Increases in production were proven to be part of the rising trend for all sectors. → Only 5 sectors' consumption were negatively affected by efficiency improvements. -- Abstract: South Africa's electricity consumption has shown a sharp increase since the early 1990s. Here we conduct a sectoral decomposition analysis of the electricity consumption for the period 1993-2006 to determine the main drivers responsible for this increase. The results show that the increase was mainly due to output or production related factors, with structural changes playing a secondary role. While there is some evidence of efficiency improvements, indicated here as a slowdown in the rate of increase of electricity intensity, it was not nearly sufficient to offset the combined production and structural effects that propelled electricity consumption forward. This general economy-wide statement, however, can be misleading since the results, in essence, are very sector specific and the inter-sectoral differences are substantial. Increases in production were proven to be part of the rising trend for all sectors. However, only five out of fourteen sectors were affected by efficiency improvements, while the structural changes affected the sectors' electricity consumption in different ways. These differences concerning the production, structural and efficiency effects on the sectors indicate the need for a sectoral approach in the energy policy-making of the country rather than a blanket or unilateral economy-wide approach.

  20. Price elasticity of natural gas demand in the power generation sector

    International Nuclear Information System (INIS)

    McArdle, P.F.

    1990-01-01

    Today, the demand for energy by the electric generation sector is highly competitive and price-responsive. Previous estimates of the price elasticity of natural gas demand in this sector have focused primarily on data from the 1960s and 1970s. Such estimates fail to take full account of economic, regulatory, and legislative developments that have altered the structure of the electric generation market during the 1980s. Structural changes include an increased ability of utilities to choose among generating options, the increase in non-utility generators, the amending of the Fuel Use Act, and a more competitive market for electricity. An accurate estimate of price elasticity requires a refocusing on data from the post-1983 period. The purpose of this paper is to answer two questions: how price responsive (elastic) is natural gas demand in this market; and what changes in natural gas demand elasticity have occurred over time

    2010-07-01

    This paper presented a case study undertaken in Oman involving the use of a proposed hybrid diesel-photovoltaic distributed power system to reduce carbon dioxide (CO{sub 2}) emissions. A model of the hybrid power system comprising a photovoltaic module, a diesel generator, and essential auxiliary devices was presented. Solar energy was selected for the Distributed Generation Technology (DGT) because Oman has an abundance of direct solar radiation. A typical house located in a remote area was considered to determine the potential greenhouse gas reduction and the economic feasibility when it is powered by the proposed hybrid system, the diesel system alone, and the main interconnected grid. The Hybrid Optimization Model for Electricity Renewables (HOMER) software was used for energy simulation, economic analysis, and the calculation of greenhouse gas (GHG) emissions. The results of the simulation indicated that the proposed hybrid system would reduce CO{sub 2} emissions by 38 percent relative to the stand-alone diesel system and by 2.67 percent compared to the main grid. The hybrid system has lower operating costs and a lower per-unit energy cost than the diesel system, but the per-unit energy cost estimated for the main interconnected system is better. The latter system is less favourable for GHG emissions. Extending the hybrid system to the entire residential sector has the potential to substantially reduce GHG emissions. The proposed hybrid system is also a cost effective choice for remote locations. 18 refs., 8 tabs., 7 figs.

    This paper demonstrates secondary aerosol generation potential of biofuel use in the energy sector from the photochemical interactions of precursor gases on a life cycle basis. The paper is divided into two parts-first, employing life cycle analysis (LCA) to evaluate the extent of the problem for a typical biofuel based electricity production system using five baseline scenarios; second, proposing adequate mitigation options to minimise the secondary aerosol generation potential on a life cycle basis. The baseline scenarios cover representative technologies for 2010 utilising energy crop (miscanthus), short rotation coppiced chips and residual/waste wood in different proportions. The proposed mitigation options include three approaches-biomass gasification prior to combustion, delaying the harvest of biomass, and increasing the geographical distance between the biomass plant and the harvest site (by importing the biofuels). Preliminary results indicate that the baseline scenarios (assuming all the biomass is sourced locally) bear significant secondary aerosol formation potential on a life cycle basis from photochemical neutralisation of acidic emissions (hydrogen chloride and sulphur dioxide) with ammonia. Our results suggest that gasification of miscanthus biomass would provide the best option by minimising the acidic emissions from the combustion plant whereas the other two options of delaying the harvest or importing biofuels from elsewhere would only lead to marginal reduction in the life cycle aerosol loadings of the systems.

    2016-01-01

    This paper provides a comprehensive analysis of the market power problem in the Spanish power generation sector and examines how and to which extent the market has developed in terms of market power concerns after the market liberalization reforms. The methodology applied in this study includes typical ex-post structural and behavioral measures employed to estimate potential for market power, namely: concentration ratios (CR) (for the largest and the three largest suppliers), the Herfindahl–Hirschman Index (HHI), Entropy, Pivotal Supply Index, the Residual Supply Index and Residual Demand Elasticity (RDE). The results are presented for the two largest Spanish generating companies (Endesa and Iberdrola) acting in the Iberian Electricity Market (MIBEL), and in the Spanish Day-ahead electricity market. The results show evidence that these companies have behaved much more competitively in recent periods than in the beginning of the market liberalization. In addition, the paper discusses important structural and regulatory changes through market liberalization processes in the Spanish Day-ahead electricity market. - Highlights: •Competition and regulation in the Spanish electricity market. •The methodology applied in this study: ex-post structural and behavioral measures. •Key dominant companies behaved more competitively in recent periods. •Important structural and regulatory changes in the Spanish electricity market.

    Granic, G.

    2005-01-01

    The paper analyzes the energy sector in the period from 1990 to 2005. What is shown here through an analysis of political, economic, energy, technological and institutional processes, and based on actual developments and non-developments, the consequences on energy situation to be evolved in the next 15 years, are analyzed. A crucial characteristic of this period is the fact that consumption growth is more distant from the trends in the developed countries and is increasingly approaching ones occurring in developing and undeveloped countries. The other such characteristic is lack of technological progress, which could generate desirable structural changes in energy production and demand. Taking in consideration what has been accomplished so far and what has not been accomplished, we cannot expect in the coming period the changes that could significantly modify the relations in the structure of energy production and demand. Keeping the balance between production and demand will be increasingly difficult, as well as keeping the influence on energy prices which will be growing. In this, it is more than ever indispensable that the state takes up its role.(author)

    The electric power sector is one of the primary sources of CO 2 emissions. Analyzing the influential factors that result in CO 2 emissions from the power sector would provide valuable information to reduce the world's CO 2 emissions. Herein, we applied the Divisia decomposition method to analyze the influential factors for CO 2 emissions from the power sector from 11 countries, which account for 67% of the world's emissions from 1990 to 2013. We decompose the influential factors for CO 2 emissions into seven areas: the emission coefficient, energy intensity, the share of electricity generation, the share of thermal power generation, electricity intensity, economic activity, and population. The decomposition analysis results show that economic activity, population, and the emission coefficient have positive roles in increasing CO 2 emissions, and their contribution rates are 119, 23.9, and 0.5%, respectively. Energy intensity, electricity intensity, the share of electricity generation, and the share of thermal power generation curb CO 2 emissions and their contribution rates are 17.2, 15.7, 7.7, and 2.8%, respectively. Through decomposition analysis for each country, economic activity and population are the major factors responsible for increasing CO 2 emissions from the power sector. However, the other factors from developed countries can offset the growth in CO 2 emissions due to economic activities.

    2014-01-01

    Full Text Available An analytical framework is developed for the vibration analysis of annular sector plates with general elastic restraints along each edge of plates. Regardless of boundary conditions, the displacement solution is invariably expressed as a new form of trigonometric expansion with accelerated convergence. The expansion coefficients are treated as the generalized coordinates and determined using the Rayleigh-Ritz technique. This work allows a capability of modeling annular sector plates under a variety of boundary conditions and changing the boundary conditions as easily as modifying the material properties or dimensions of the plates. Of equal importance, the proposed approach is universally applicable to annular sector plates of any inclusion angles up to 2π. The reliability and accuracy of the current method are adequately validated through numerical examples.

    To determine the role of rhodopsin (RHO) gene mutations in patients with sector retinitis pigmentosa (RP) from Northern Ireland. A case series of sector RP in a tertiary ocular genetics clinic. Four patients with sector RP were recruited from the Royal Victoria Hospital (Belfast, Northern Ireland) and Altnagelvin Hospital (Londonderry, Northern Ireland) following informed consent. The diagnosis of sector RP was based on clinical examination, International Society for Clinical Electrophysiology of Vision (ISCEV) standard electrophysiology, and visual field analysis. DNA was extracted from peripheral blood leucocytes and the coding regions and adjacent flanking intronic sequences of the RHO gene were polymerase chain reaction (PCR) amplified and cycle sequenced. Rhodopsin mutational status. A heterozygous missense mutation in RHO (c.173C > T) resulting in a non-conservative substitution of threonine to methionine (p. Thr58Met) was identified in one patient and was absent from 360 control individuals. This non-conservative substitution (p.Thr58Met) replaces a highly evolutionary conserved polar hydrophilic threonine residue with a non-polar hydrophobic methionine residue at position 58 near the cytoplasmic border of helix A of RHO. The study identified a RHO gene mutation (p.Thr58Met) not previously reported in RP in a patient with sector RP. These findings outline the phenotypic variability associated with RHO mutations. It has been proposed that the regional effects of RHO mutations are likely to result from interplay between mutant alleles and other genetic, epigenetic and environmental factors.

    Distributed generation has become an alternative for the lack of resources to large energy projects and for recent facts that have changed the geopolitical panorama. The later have increased oil prices so that unconventional sources have become more and more feasible, which is an issue usually discussed in Europe and in USA. Brazil has followed such world trend by restructuring the electrical sector as well as major related institutions, from generation to commercialization and sector regulation while local legislation has enabled the increase of distributed generation. It regulates the role of the independent energy producer so as to provide direct business between the later and a great consumer, which is an essential step to enlarge energy market. Sugarcane bagasse has been used to produce both electric energy and steam and this paper analyzes and discusses the major implications of a new model for Brazilian electric sector based on sugarcane bagasse use as means to increase distributed generation process, particularly concerned with the commercialization of energy excess.

    Full Text Available Energy security defined as how to equitably provide available, affordable, reliable efficient, environmentally friendly, proactively governed and socially acceptable energy services to end user. It has in recent years taken attention of policymakers in different parts of the world. Formulating policy to improve energy security is mandatory, not only because of depleting fossil resource, but also implementing diversity of energy source since utilization abundant renewable energy resources can increase the security of energy supply. One of the abundant renewable energy resources in Indonesia is palm oil. This study analyses the utilization of palm biodiesel for Indonesian power generation sector in the Java-Madura-Bali (JAMALI system. Two scenarios were created by projecting the demand and environmental impact as well as GHG emissions reduction over the next 25 years. The first scenario subjects on current energy policy, while the second scenario is to substitute of fossil fuel which is still used in the JAMALI power generation system. Effect of palm biodiesel on emission of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, Nitrogen Oxides, Particulate Matter, and Volatile Organic Compounds were estimated for each scenario. An externality analysis to complete the environmental analysis was conducted and resource analysis of palm oil plantation based biodiesel was also estimated. Finally, the economics feasibility of palm biodiesel in the power generation sector was analyzed.

    India suffers from widespread shortages of electricity supply. These shortages, among others, are detrimental to the economic growth. The prospects for the next decade do not seem to be much brighter. Efforts in expanding generation capacity by the state-owned electric utilities are hampered by severe resource constraints. Against this backdrop, to mobilize additional resources to help bridge the gap in demand and supply, the Government of India formulated a policy in 1991 with the objective to encourage greater investment by private enterprises in the electricity sector. To study the implications of such an initiative on various stakeholders, viz., public utilities, consumers and private sector, the present paper tries to analyse issues like planned rationing, guarantees to private sector, backing down of existing capacity. Using the state of Karnataka (in Southern India) as a case study, the paper develops multiple scenarios using an integrated mixed integer-programming model. The results show the advantage of marginal non-supply (rationing) of electricity in terms of achieving overall effective supply demand matching as well as providing economic benefits to the state that could be generated through cost savings. The results also show the negative impacts of high guarantees offered to the private sector in terms of the opportunity costs of reduced utilization of both the existing and the new public capacity. The estimated generation losses and the associated economic impacts of backing down of existing and new public capacity on account of guarantees are found to be significantly high. For 2011-12, depending on the type of scenarios, the estimated generation and economic losses are likely to be in the range of 3200-10,000 GWh and Rs. 4200-13,600 million respectively. The impact of these losses on the consumers could be in terms of significant increase in energy bills (in the range of 19-40% for different scenarios) due to rise in tariffs

    The present research study used the quantitative approach to analyze the present and future situation of the Venezuelan power generation sector; to achieve that, the total energy generation costs and GHG emissions of four scenarios in 2050 were estimated and compared, considering two demand groups, high and low demand. For each demand scenario, two supply matrix were considered, a generation matrix based on the existing national power generation plans and trends (these scenarios were referred as BAU) and a configuration based on the renewable energy resources available in Venezuela and without the use of either nuclear or CCS technologies, and these scenarios are referred as Sustainable Scenarios (SUS). In the first section, the present situation is presented, followed by an explanation of the applied methodology and the implemented tools. In the third and fourth sections the available recourses and the applied basic assumptions for the four of scenarios are presented and discussed, respectively, followed by the results. In this study it is shown that Venezuela has all the resources it needs to achieve sustainable development in the power generation sector. It is also proved that an energy efficiency improvement is the easiest path to reduce GHG emissions. - Highlights: ► Venezuela has enough energy resources to supply the energy require for its development. ► A sustainable scenario is posible in Venezuelan power generation sector in 2050. ► The sustainable scenario is technically possible without nuclear power or carbon capture storage technologies. ► The impact over the depleatable resources is higher under the BAU assumptions.

    2011-01-01

    Market-based instruments, particularly carbon tax, have recently drawn the attention of Chinese government by their cost-effective contribution to the achievement of China's climate targets. Most of the recent policy proposals have focused on its long-term impact. However, particularly for policy makers, both long term and short term effects of carbon tax would be necessary when determining tax rates. We provided a detailed analysis of short-term impacts of carbon tax on sectoral competitiveness in this paper. We divided China's economy into 36 sectors, based on its 2007 input-output table, in order to examine the ratio of carbon tax added costs to sector GDP. We were thus able to determine the impact level of a carbon tax on each sector. We then divided the sectoral trade impact into domestic competitiveness with regards to foreign imported products and international competitiveness external to the Chinese domestic market. We found that a high tax level (100 yuan/t CO 2 ) may necessitate compensatory measures to certain highly affected industries, and that a low tax rate (10 yuan/t CO 2 ) would generate few competitiveness problems for all industries and may therefore be considered as an appropriate starting point. - Highlights: → We study short-term sectoral competitiveness impact of carbon tax in China. → For each sector, we study its carbon cost, GDP share and trade intensity. → A high rate (100 yuan/t CO 2 ) may require compensatory measures to certain industries. → A low rate (10 yuan/t CO 2 ) would generate few competitiveness problems.

    2017-12-01

    Full Text Available This paper provides an analysis of the debt burden of Russian companies and raises the issue of debt-level heterogeneity across economic sectors. To identify the causes of this heterogeneity, it estimates a regression model that includes both fundamental explanatory variables of companies and industry fixed effects. The results of the analysis demonstrate that standard variables, such as profitability, company size, asset turnover, and fixed-asset turnover ratio have a strong statistical significance. However, these do not fully explain the variation in the debt levels of companies in different sectors. According to model estimation, there are other industry specific factors that produce an imbalance between fundamental factors and companies’ debt levels. An understanding of the formation process and structure of debt burden in individual industries is extremely important for the financial stability of companies and for an effective monetary policy.

  9. Higgs data does not rule out a sequential fourth generation with an extended scalar sector

    Das, Dipankar; Kundu, Anirban; Saha, Ipsita

    2018-01-01

    Contrary to common perception, we show that the current Higgs data does not eliminate the possibility of a sequential fourth generation that get their masses through the same Higgs mechanism as the first three generations. The inability to fix the sign of the bottom-quark Yukawa coupling from the available data plays a crucial role in accommodating a chiral fourth generation which is consistent with the bounds on the Higgs signal strengths. We show that effects of such a fourth generation can remain completely hidden not only in the production of the Higgs boson through gluon fusion but also to its subsequent decay to γ γ and Z γ . This, however, is feasible only if the scalar sector of the standard model is extended. We also provide a practical example illustrating how our general prescription can be embedded in a realistic model.

    Full Text Available The increase in productivity in the maritime sector will realize the maritime sector as a prime mover. This study aims to analyze the impact of the maritime sector productivity improvement on the performance of the economy. This research simulates increased productivity in the maritime sector (consisting of the fisheries, oil, gas sub-sector and marine transport services sector using the Global Trade Analysis Project (GTAP version 8. Simulation analysis showed an increase in productivity in the maritime sector has a positive impact on welfare, real GDP, and trade balance of Indonesia. However, the impact of the increase in productivity is not followed by an increase in output in all sectors. This indicates that if the increase in productivity occurs only in the maritime sector alone without being followed by an increase in productivity in other sectors, the sectoral performance is not optimal.DOI: 10.15408/sjie.v5i2.3403

    Development of the district heating system in the FR Yugoslavia, beside the combined generation of electric and heating energy presents a necessity for energy, economic and ecological reasons. Although the structure of energy reserves is rather unfavourable considering that the lignite is being predominantly used, available reserves of energy raw material are able to ensure the long-term development of Yugoslav energy sector, and to offer real possibilities for considerable substitution of foreign good quality fuels, especially in district heating systems. Their further development will depend, among other things: on the implementation of new technological solutions for the exploitation of local energy resources; need of reconstruction, revitalisation and transformation of old condensing thermal power plants into the cogeneration plants; installation of remote controlled transmission of heating energy as well as on development of heating plants and smaller co-generation plants based on local energy resources.

    2008-08-01

    Full Text Available Porter’s model of Competitive advantage of nations (named as Diamond Model has been widely used and criticized as well, over recent two decades. On the other hand, non-mainstream economists have tried to propose new frameworks for industrial analysis, that among them, Sectoral Innovation System (SIS is one of the most influential ones. After proposing an assessment framework, we use this framework to compare SIS and Porter’s models and apply them to the case of second mobile operator in Iran. Briefly, SIS model sheds light on the innovation process and competence building and focuses on system failures that are of special importance in the context of developing countries, while Diamond model has the advantage of brining the production process and the influential role of government into focus, but each one has its own shortcomings for analyzing industrial development in developing countries and both of them fail to pay enough attention to foreign relations and international linkages.

    Changes are occurring throughout the U.S. economy, especially in regard to how energy is generated and used in the electricity, buildings, industrial, and transportation sectors. These changes are being driven by environmental and energy security concerns and by economics. The electric-sector market share of natural gas and variable renewable generation, such as wind and solar photovoltaics (PV), continues to grow. The buildings sector is evolving to meet efficiency standards, the transportation sector is evolving to meet efficiency and renewable fuels standards, and the industrial sector is evolving to reduce emissions. Those changes are driving investment and utilization strategies for generation and other assets. Nuclear and renewable energy sources are important to consider in the energy sector’s evolution because both are considered to be clean and non-carbon-emitting energy sources. The Idaho National Laboratory (INL) and the National Renewable Energy Laboratory (NREL) are jointly investigating potential synergies between technologies exploiting nuclear and renewable energy sources. The two laboratories have held several joint workshops since 2011. Those workshops brought together experts in both areas to identify synergies and potential opportunities to work together. Workshop participants identified nuclear-renewable hybrid energy systems (N-R HESs) as one of the opportunities and recommended investigating whether N-R HESs could both generate dispatchable electricity without carbon emissions and provide clean energy to industrial processes. They also recommended analyzing the potential for N-R HESs to provide dispatchable capacity to a grid with high penetrations of non-dispatchable resources and to investigate whether real inertia provided by thermal power cycles within N-R HESs provides value to the grid. This report is one of a series of reports INL and NREL are producing to investigate the technical and economic aspects of N-R HESs. Previous reports

    The obligations resulting from the Kyoto Protocol (KP) are implemented by many participants, e.g. Greece, by a combination of two methods: (a) application of regional measures which restrict CO 2 emissions and (b) procurement of green certificates e.g. in a Climate Exchange Market (CEX). Therefore, the cost for compliance with the KP depends on the extent each method is used and also on the traded values in the CEX. The energy policy and planning to be considered are long-term items and now extension of the KP to a post-KP is discussed which reaches year 2020. In Greece, the electricity sector is with a weighted CO 2 contribution of 73%, the dominantly emission sector. The paper analyzes the cost and other merits of different scenarios for the expansion of electrical power system in Greece. For different scenarios, the total cost of the electrical power system expansion is calculated as a function of the price of emission certificates. It has been shown that there is a price of 27.5 Euro /tCO 2 , above which specific mitigation measures may lead to cost optimum solutions. A sensitivity analysis is also presented concerning the variation of key parameters like the participation in the system expansion of new supercritical coal units, the price evolution of natural gas, the RES usage rate and the discount rates of the expansion investments. Results may be of interest for a decision on the cost optimum electrical power system expansion

  9. Cost benefit analysis of policy measures in the transport sector

    Buus Kristensen, N [COWI (Denmark)

    1996-12-01

    The Government has introduced a national target for the reduction of CO{sub 2} emissions from the transport sector, which aims to stabilize emissions at the 1988 level, by the year 2005. This target was first formalized in the Government`s 1990 transport action plan, and later repeated in `Traffic 2005`, published in December 1993. The latter document also makes reference to six strategies, which the Government proposed in order to attain the national target. The majority of the transport policy measures will impact on CO{sub 2} emissions from the sector, even if they are targeted at different objectives, e.g. road safety, air pollution, time savings, etc. A long-list of potential measures, which might be adopted with the primary purpose is to reduce CO{sub 2} emissions, has been identified from the six overall strategies. The measures identified have been subjected to detailed analyses, to ascertain all the potential impacts. The main emphasis has been on clarifying the potential efficacy of each of the measures in reducing CO{sub 2} emissions, and the social costs in a wide sense. The analysis assumes that each policy measure is implemented separately. A methodology is developed that presents the respective consequences in commensurate terms. Similar calculations are undertaken for two different combinations of policy measures. (EG)

  10. The Impact of Chinese FDI on Employment Generation in the Building and Construction Sector of Ghana

    2015-07-01

    Full Text Available One of the major concerns of governments in Africa in general and Ghana in particular is unemployment and underemployment. Most developing countries especially African countries compete to attract foreign direct investment (FDI into their economies with the desire of improving employment level and securing a sustainable development leading to economic growth. In view of this, the creation of jobs for the unemployed and technology transfer through Chinese investments has become complementary since Chinese FDI can be an important source for employment, economic growth and transformation processes. This study focuses on the contribution of China’s FDI on employment generation in the building and construction sector of Ghana. By using a robust regression model, the results show that, Chinese FDI flows on employment through direct effects on building and construction sector of Ghana have positive and significance on employment growth. This means that, Chinese FDI contributes to an efficient workforce which benefits an economy from high productivity and leads to growth in individual household incomes.

    This study for the U.S. Bureau of Reclamation examines conditions in the electricity sector that are likely to affect federal decisions with respect to Navajo Generating Station (NGS), the largest coal-fired power plant operating in the western United States. The federal government owns 24.3% of the 2.25-gigawatt plant, which amounts to 547 megawatts (MW) of capacity. By focusing on the unique public interests that depend on the federal share of NGS, this baseline study can help the federal government develop a road map for meeting all of its goals with respect to water delivery, clean energy, emission reduction, and economic development. There is no recommendation for action in this report. Rather, its aim is to provide a credible, thorough description of baseline conditions that might affect federal decisions regarding NGS. It describes facts and trends embedded in current data, but there are no conclusions about how Reclamation or DOI should respond to the trends. The interdependencies among the many sectoral trends and federal goals are complex, and the aim of this study is to provide a foundation from which options can be tested in a deliberate manner.

  12. Climate change policies analysis of sectoral changes in Europe

    2004-01-01

    This study addresses the following question, at the core of Europe's climate policy: Beyond the question of the European Union's ability to meet its emissions commitments under the Kyoto Protocol, are sectoral emissions trends displaying structural changes deemed necessary to reduce emissions, and to attain levels that are consistent with the UNFCCC greenhouse gas concentration stabilisation objectives? What lessons can we draw from emissions trends for the EU future climate policy? Greenhouse gas emissions have been stable for the last decade, but mostly due to events and policy developments unrelated to climate policy, and unlikely to be reproduced in other countries: Germany's reunification, substitution from coal to gas in the United Kingdom driven by power market reform. We should not expect changes of such magnitude in the near future. The issue of our future climate policy hence requires a closer look at underlying trends. Industry's direct emissions decreased thanks to constant improvements in energy efficiency and to the substitution of electricity to direct fossil fuel use. In spite of efficiency gains in the residential sector, increasing floor space and level of equipment entail growing energy consumption. Smaller-size households are now spreading to Southern European countries and should be expected in new Member states as well. Turning to the tertiary/services sector, we find that value added and floor space grew significantly over the decade - 35% and 32% respectively in the EU-15. There again, energy efficiency improvements do not compensate for growing floor spaces. Transport's growth, especially freight, has been significant in all countries. The highest rates of traffic growth per unit of gross domestic product are in Spain and Portugal, two countries where rail infrastructure is fairly limited. CO 2 emissions from transport grew by 18% in the EU between 1990 and 2000. Power generation's CO 2 emissions have decreased slightly in spite of strong

    In this research we consider a modified version of quantum electrodynamics in four dimensions with the coupling between the photon and the fermion composed by two terms: a nonminimal and the minimal one. There are two interesting aspects in this model. First, gauge invariance is restored by the presence of the minimal coupling. Second, the quantum corrections will allow for the possibility of the generation of a Chern-Simons-like term. The fact that the model is gauge invariant allows for a more complete analysis on the value of both the coefficients of the hypothetical CPT odd and CPT even radiatively generated terms. A question that arises involves a possible violation of some Ward-Takahashi identity when radiative corrections are taken into account. In other words, is there an anomaly in the model? We show that, since conventional QED is gauge invariant, there is no room for a non transversal vacuum polarization tensor in the present model. This is study is to be presented in the following order: first we are to present the model; second we do an analysis on the generation of Lorentz violating terms in the pure gauge sector; third we carry out a calculation on gauge invariance grounds to fix the coefficients of the quantum corrections; and lastly the concluding comments.

  15. Freer markets and the abatement of carbon emissions. The electricity-generating sector in India

    International Nuclear Information System (INIS)

    Khanna, Madhu; Zilberman, David

    1999-01-01

    This paper develops a framework to explore the implications of trade and domestic policy distortions for the magnitude of carbon emissions and for the welfare costs of abating these emissions. An application to the electricity-generating sector in India shows that economic policy reforms can also be effective environmental policy instruments and reduce carbon emissions even in the absence of an emissions tax. This reduction in emissions is accompanied by an increase in domestic welfare, an increase in electricity output, and conservation of coal. Coordinating trade and domestic policy reform with an emissions tax policy reduces emissions further, while leading to gains in welfare that are greater than those under an emissions tax policy alone

    This article provides a first-cut estimate of the potential impacts of the clean development mechanism (CDM) on electricity generation and carbon emissions in the power sector of non-Annex 1 countries. We construct four illustrative CDM regimes that represent a range of approaches under consideration within the climate community. We examine the impact of these CDM regimes on investments in new generation, under illustrative carbon trading prices of US$ 10 and 100/tC. In the cases that are most conductive to CDM activity, roughly 94% of new generation investments remains identical to the without-CDM situation, with only 6% shifting from higher to lower carbon intensity technologies. We estimate that the CDM would bolster renewable energy generation by as little as 15% at US$ 10/tC, or as much as 300% at US$ 100/tC. A striking finding comes from our examination of the potential magnitude of the 'free-rider' problem, i.e. crediting of activities that will occur even in the absence of the CDM. The CDM is intended to be globally carbon-neutral --- a project reduces emissions in the host country but generates credits that increase emissions in the investor country. However, to the extent that unwarranted credits are awarded to non-additional projects, the CDM would increase global carbon emissions above the without-CDM emissions level. Under two of the CDM regimes considered, cumulative free-riders credits total 250-600MtC through the end of the first budget period in 2012. This represents 10-23% of the likely OECD emissions reduction requirement during the first budget period. Since such a magnitude of free-rider credits from non-additional CDM projects could threaten the environmental integrity of the Kyoto protocol, it is imperative that policy makers devise CDM rules that encourage legitimate projects, while effectively screening out non-additional activities.

    This paper describes a method, developed for the Gas Research Institute of the United States, that can assist planning for commercial sector natural gas cooling systems R and D. These systems are higher in first cost than conventional electric chillers. Yet, engine-driven chiller designs exist which are currently competitive in U.S. markets typified by high electricity or demand charges. Section II describes a scenario analysis approach used to develop and test the method. Section III defines the technology frontier, a conceptual tool for identifying new designs with sales potential. Section IV describes a discrete choice method for predicting market shares of technologies with sales potential. Section V shows how the method predicts operating parameter, cost, and/or performance goals for technologies without current sales potential (or for enhancing a frontier technology's sales potential). Section VI concludes with an illustrative example for the Chicago office building retrofit market

  19. An analysis of Grenada's power sector and energy resources: a role for renewable energy technologies?

    Wiesser, D.

    2004-01-01

    Presently, Grenada's power sector is fully dependent on fossil fuel imports for meeting the country's electricity demand. Electric utilities in Small Island Developing States (SIDS), in general, face high cost of electricity generation due to diseconomies of scale in production, consumption and logistical aspects. Grenada's private power monopoly is no exception and the high cost of import dependent electricity generation places an increasing burden on economic development. In light of rapid technological and economic improvement of renewable energy technologies (RETs), the country's abundant sources of renewable energy should be harnessed. Benefits are envisaged to include lower electricity cost, better environmental performance and a safer and diversified supply of energy. However, barriers for shifting power production towards meaningful contributions from RETs exist, both in government and industry. This work analyses important economic interactions between the power sector and economic development, bringing to attention the importance of power sector reform. Further, present problems of integrating RETs into the grid, ranging from technical and regulatory issues to shareholder interest are investigated. A summary and analysis of past research into renewable sources of energy (RES) underscore the potential for power production from RETs in Grenada. (author)

  20. Energy efficiency in the transport sector in the EU-27: A dynamic dematerialization analysis

    Energy use in the European Union's (EU) transport sector amounted to 340 Mtoe in 1999 with the following increasing trend up to 379 Mtoe in 2007 and a decrease from 2008 on, down to 365 Mtoe in 2010. This changing pattern posed several fundamental questions and uncertainties regarding the broader picture of energy efficiency and environmental protection. One of them refers to absolute changes in energy use efficiency in the transport sector over time and the ways of measuring efficiency. Traditional scientific approaches conceptualized to measure efficiency of energy use do not address annual dynamics of changes in the energy use in a given sector per capita. Thus, they are not precise enough for political and methodological purposes as they do not reflect the exact amount of energy consumed in the respective countries and societies. This paper shows a possible solution to this problem and a new perspective on measuring energy efficiency by using the product generational dematerialization (PGD) indicator. The PGD indicator allows for measuring energy efficiency as a dynamic change of consumption and population occurring simultaneously. Thus, it provides an extension to the traditional methodology commonly used for measuring efficiency. To visualize a practical application of this approach, the paper provides an example of evaluating energy efficiency in the transport sector in the EU-27 in 2000–2010. The results of the analysis show a clear materialization tendency in the transport sector (the energy consumption change exceeded the population growth) until 2007 and a reverse tendency (dematerialization) between 2008 and 2010. As energy consumption has a direct impact on environmental quality and exhaustion of natural resources, the paper points out the necessity of extending sustainable resource management policies by new methodologies and providing more efficient solutions for energy consumption in the transport sector. - Highlights: • PGD indicator proves a

    2014-01-01

    As the President of the Office of Competition and Consumer Protection refused to approve a government initiated takeover in the Polish power sector and the Court of Competition and Consumer Protection did not make a ruling on that case, the takeover was finally prohibited. In this context, the main aim of this paper is to carry out a quantitative analysis of the impact of the takeover in question on electricity prices and quantities, consumer and producer surpluses, dead weight loss and emissions. The scope of the study covers the Polish power generation sector and the analysis was carried out for 2009. A game theory-based electricity market equilibrium model developed for Poland was applied. The model includes several country-specific conditions, such as a coal-based power generation fuel-mix, a large share of biomass co-combustion, etc. For the sake of clarity, only four scenarios are assumed. The paper concludes that the declared synergy savings did not compensate for the increase in dead weight loss and the transfer of surplus from consumers to producers caused by increased market power. - Highlights: • A takeover blocked by the President of the Office of Competition and Consumer Protection was analysed. • A game theory-based model of the Polish wholesale electricity market was applied. • The impact of the takeover on electricity prices and generation levels, surplus transfers and dead weight loss was estimated. • The results were compared with the declared synergy savings

    In recent years, research activities regarding the global environmental impacts of carbon dioxide (CO{sub 2}) emissions have been intensified. The carbon market aims to minimize the emissions of this dangerous gas as it allows incentives for developed and developing countries to be stimulated not to adjust to a high carbon dioxide energy matrix. This work studies the carbon dioxide emissions and capture mass balance in the sugar and alcohol sector. Through a life cycle analysis methodology of surplus electricity production the CO{sub 2} balance is calculated. The results obtained show that 145,3 tons CO{sub 2}/hectare are sequestered during sugarcane cultivation and 111,5 tons CO{sub 2}/hectare are emitted for electricity production, resulting in a viable capture balance scenario of 33,8 tons of carbon dioxide per hectare of plantation in one life cycle of surplus electricity production that is supplied to the electricity distribution companies. The life cycle analysis of the cultivation of sugarcane biomass for surplus electricity production allowed a high value to be obtained for the CO{sub 2} absorption figure. If compared with other forms of electricity generation, the energy produced in sugar mills presents the lowest values of carbon dioxide emissions of all the other forms of electricity production.

    2013-05-01

    Full Text Available This article reflects the use of urban space by women in urban informal sectors in the city of Guwahati located in North East India. The population influx from across the borders in the aftermath of the partition has huge implications both on polity and on economy of the northeastern states in general and Assam in particular.  Importantly, the urban informal sectors have a sizeable share in terms of its significant contributions towards Gross Domestic Product (GDP as well as generation of employment opportunities largely. Using a feminist perspective, the research is an attempt to investigate the engagement of women in the informal sector in greater Guwahati. Research findings reveal that the occupations of the women workers are location-specific, that is, the manufacturing sectors (textiles, food preparation, printing and skilled service are mainly home/shop based production (fixed locations whereas the service sectors (leisure, caring, elementary construction, elementary sales and cleaning occupation operate at variable locations (construction sites, street pavements, marketplaces and other various locations. Further analysis shows that the informal sector is highly demand dependent and such demands are in the central business areas of the city, therefore informal sector services (skilled services and elementary services are found to be located in and around the central areas of Guwahati city. Women operators in the informal sector are attracted to the central business district because of the many advantages that it enjoys relative to other parts of a city. The paper concludes by calling on policy makers and physical planning agencies to evolve more pragmatic strategies for urban development matters in order that urban informal sector activities can be integrated into urban development plans. Finally, further research is called for on how urban planners could redesign the urban space with appropriate consideration of the informal sector

    In this paper, sectoral energy and exergy analysis model is applied to the utility and commercial sectors of Malaysia by considering the energy and exergy flows from 1990 to 2003. The energy and exergy efficiencies are determined for the sub-sectors and devices used in these two sectors. It has been found the hydroelectric power plant sub-sector is more energy and exergy efficient compared to the thermal power plant sub-sector. The energy and exergy efficiencies of utility and commercial sectors of Malaysia are compared with a few other countries around the world as well. The utility and commercial sectors of Malaysia are found to be more efficient than that of Thailand, Brunei, China, and Vietnam in 1999

  8. Financial vulnerability of the electricity sector to drought, and the impacts of changes in generation mix

    Electric power utilities are increasingly cognizant of the risks water scarcity and rising temperatures pose for generators that use water as a "fuel" (i.e., hydroelectric dams) and generators that use water for cooling (i.e., coal, natural gas and nuclear). At the same time, utilities are under increasing market and policy pressure to retire coal-fired generation, the primary source of carbon emissions in the electric power sector. Due to falling costs of renewables and low natural gas prices, retiring coal fired generation is mostly being replaced with combined cycle natural gas, wind and solar. An immediate benefit of this shift has been a reduction in water withdrawals per megawatt-hour and reduced thermal impacts in surface water systems. In the process of retiring older coal-fired power plants, many of which use water intensive open-loop cooling systems, utilities are making their systems less vulnerable to water scarcity and higher water temperatures. However, it is not clear whether financial risks from water scarcity will decrease as result of this change. In particular, the choice to replace coal with natural gas combined cycle plants leaves utilities financially exposed to natural gas prices, especially during droughts when natural gas generation is used to replace lost hydropower production. Utility-scale solar, while more expensive than natural gas combined cycle generation, gives utilities an opportunity to simultaneously reduce their exposure to water scarcity and fuel price risk. In this study, we assess how switching from coal to natural gas and solar changes a utility's financial exposure to drought. We model impacts on retail prices and a utility's rate of return under current conditions and non-stationarity in natural gas prices and temperature and streamflows to determine whether increased exposure to natural gas prices offsets corresponding gains in water use efficiency. We also evaluate whether utility scale solar is an effective hedge

    Performance-based regulation (PBR) enables regulators to reform hundred-year-old regulatory structures to unleash innovations within 21st century power systems. An old regulatory paradigm built to ensure safe and reliable electricity at reasonable prices from capital-intensive electricity monopolies is now adjusting to a new century of disruptive technological advances that change the way utilities make money and what value customers expect from their own electricity company. Advanced technologies are driving change in power sectors around the globe. Innovative technologies are transforming the way electricity is generated, delivered, and consumed. These emerging technology drivers include renewable generation, distributed energy resources such as distributed generation and energy storage, demand-side management measures such as demand-response, electric vehicles, and smart grid technologies and energy efficiency (EE). PBR enables regulators to recognize the value that electric utilities bring to customers by enabling these advanced technologies and integrating smart solutions into the utility grid and utility operations. These changes in the electric energy system and customer capacities means that there is an increasing interest in motivating regulated entities in other areas beyond traditional cost-of-service performance regulation. This report addresses best practices gleaned from more than two decades of PBR in practice, and analyzes how those best practices and lessons can be used to design innovative PBR programs. Readers looking for an introduction to PBR may want to focus on Chapters 1-5. Chapters 6 and 7 contain more detail for those interested in the intricate workings of PBR or particularly innovative PBR.

    The preliminary sample for the analysis is framed on the basis of three criteria: amount of the subscribed capital, sales revenues and product structure. Those companies are regarded as competitors that have subscribed capitals in excess of HUF 250 million, consistently high levels of sales revenues and diversified product structures. The preliminary sample consists of 7 companies. In 2012, their total sales revenues were as high as about 50% of the overall amount of sales revenues in the sector. Three of the 7 companies are possessed by foreign owners in full or part, whereas 4 of them belong to Hungarian owners. In 2012, Hungarian-owned companies covered more than one-third of the combined sales revenues of the 7 leading companies. Hence, the competitive positions of these 4 companies based on their financial positions are examined. These calculations have relied on the annual reports for the period of 2008–2012 (balance sheets, income statements, cash flow statements. The research has implemented a comprehensive and comparative financial analysis. The main question is what the key financial characteristics of the Hungarian-owned companies are. Financial indicators are calculated and their time-series analysis is accomplished to describe the sample companies’ capital structures, liquidity and profitability. Using comparative analysis of the applied financial ratios the study determines (1 which company has the most advantageous financial conditions for the successful operation; (2 which companies have disadvantageous financial situation; and (3 which companies are in potential financial distress situation. Potential bankruptcy positions are examined by the applications of Altman and Springate models.

    As CO 2 emission is recognized as the one of the major causes of the global worming, international CO 2 emission regulation has been of great concern and has been discussed actively on the global level. Several means of CO 2 emission regulation have been raised and have received much attention recently. CO 2 emission regulation is expected to affect the national economy as well as the national energy policy. Since the electricity sector closely interacts with CO 2 emission, environmental regulation has the possibility of implementation in this sector. Considering the enormous role played by electricity in the national economy, it is very important to study the effect of environmental regulation on the electricity sector. The main purpose of this study is to estimate the marginal cost of CO 2 emission by analyzing the effect of CO 2 emission regulation on the electricity sector in terms of capacity and generation mix. This information can be used effectively in energy policy establishment. In addition, the effect of CO 2 emission regulation on economic viability of electricity generating type is also being studied in order to contribute to the establishment of Electric System Expansion Planning in Korea

    Historically, the electrical systems were constituted from local networks of small scale that were added together progressively to benefit from the effects of a more abundant demand and of the economies of scale in generation, that authorize the large interconnected systems. This logic at the moment seems to show certain limits, the factors that influence these technologies can vary greatly from one country to another, but nevertheless it is found in different degrees certain constants such as the search for a greater reliability in the electrical supply, the putting into work prevention policies of climatic change or the reforms of the electrical sector. In this work the influence of these factors was examined insisting particularly on the consequences of the opening of the electrical sector, departing from an analysis of the international experience in a first time and later examining the case of Mexico in the context of the present energy situation and the debate of the energy reform. The distributed generation: a new vector of technological opportunities in the electrical sector, the barriers for the diffusion of the distributed generation: the lessons of the international experience, the institutional problematic of the distributed generation within the effective legal framework of Mexico.

  16. Collective bargaining: An analysis of hurdles and applicability in the public sector

    Directory of Open Access Journals (Sweden)

    Daniel Chigudu

    2015-04-01

    Full Text Available This article discusses the arguments against adopting collective bargaining in the public sector and its benefits. Collective bargaining in the public sector is viewed primarily as undermining democratic governance in one way and paradoxically it is seen as an essential part of democratic governance. In the former view, collective bargaining in the public sector is seen as an interference with administrative law for personal benefit to the detriment of the taxpayer. Proponents of this view argue that unionising public sector employees encourages disloyalty to the government at the expense of public welfare. In the later view, public sector collective bargaining is viewed as a fundamental human right in a pluralistic society. Advocates of this view posit that, public sector unions provide a collective voice that stimulates improvement of government services as well as sound administration of law. They also argue that, public sector collective bargaining represents public policy interests and serves as a watchdog to government’s monopoly power in employment matters. Public sector unions raise employee salaries and perks to levels higher than they would have been in the absence of collective bargaining. These two opposite views are subjected to a critical analysis in this paper, with empirical evidence for both the benefits of public sector collective bargaining and arguments against public sector unions. The article found that public sector collective bargaining depends on the socio-economic background of states although international laws favour public sector unionism.

  17. The Impact of a Carbon Tax on the Chilean Electricity Generation Sector

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available This paper aims to analyse the economy-wide implications of a carbon tax applied on the Chilean electricity generation sector. In order to analyse the macroeconomic impacts, both an energy sectorial model and a Dynamic Stochastic General Equilibrium model have been used. During the year 2014 a carbon tax of 5 US$/tCO2e was approved in Chile. This tax and its increases (10, 20, 30, 40 and 50 US$/tCO2e are evaluated in this article. The results show that the effectiveness of this policy depends on some variables which are not controlled by policy makers, for example, non-conventional renewable energy investment cost projections, natural gas prices, and the feasibility of exploiting hydroelectric resources. For a carbon tax of 20 US$/tCO2e, the average annual emission reduction would be between 1.1 and 9.1 million tCO2e. However, the price of the electricity would increase between 8.3 and 9.6 US$/MWh. This price shock would decrease the annual GDP growth rate by a maximum amount of 0.13%. This article compares this energy policy with others such as the introduction of non-conventional renewable energy sources and a sectorial cap. The results show that the same global greenhouse gas (GHG emission reduction can be obtained with these policies, but the impact on the electricity price and GDP are lower than that of the carbon tax.

    This report summarizes Detection and Analysis of Threats to the Energy Sector (DATES), a project sponsored by the United States Department of Energy and performed by a team led by SRI International, with collaboration from Sandia National Laboratories, ArcSight, Inc., and Invensys Process Systems. DATES sought to advance the state of the practice in intrusion detection and situational awareness with respect to cyber attacks in energy systems. This was achieved through adaptation of detection algorithms for process systems as well as development of novel anomaly detection techniques suited for such systems into a detection suite. These detection components, together with third-party commercial security systems, were interfaced with the commercial Security Information Event Management (SIEM) solution from ArcSight. The efficacy of the integrated solution was demonstrated on two testbeds, one based on a Distributed Control System (DCS) from Invensys, and the other based on the Virtual Control System Environment (VCSE) from Sandia. These achievements advance the DOE Cybersecurity Roadmap [DOE2006] goals in the area of security monitoring. The project ran from October 2007 until March 2010, with the final six months focused on experimentation. In the validation phase, team members from SRI and Sandia coupled the two test environments and carried out a number of distributed and cross-site attacks against various points in one or both testbeds. Alert messages from the distributed, heterogeneous detection components were correlated using the ArcSight SIEM platform, providing within-site and cross-site views of the attacks. In particular, the team demonstrated detection and visualization of network zone traversal and denial-of-service attacks. These capabilities were presented to the DistribuTech Conference and Exhibition in March 2010. The project was hampered by interruption of funding due to continuing resolution issues and agreement on cost share for four months in 2008

  1. Concentration in the Greek private hospital sector: a descriptive analysis.

    2007-07-01

    Over the last 20 years, governments all around the world have attempted to boost the role of market and competition in health care industries in order to increase efficiency and reduce costs. The increased competition and the significant implications on costs and prices of health care services resulted in health care industries being transformed. Large firms are merging and acquiring other firms. If this trend continues, few firms will dominate the health care markets. In this study, I use the simple concentration ratio (CR) for the largest 4, 8 and 20 companies to measure the concentration of Greek private hospitals during the period 1997-2004. Also, the Gini coefficient for inequality is used. For the two different categories of hospitals used (a) general and neuropsychiatric and (b) obstetric/gynaecological it is evident that the top four firms of the first category accounted for 43% of sales in 1997, and 52% in 2004, while the four largest firms of the second category accounted for almost 83% in 1997, and 81% in 2004. Also, the Gini coefficient increases over the 8-year period examined from 0.69 in 1997 to 0.82 in 2004. It explains that the market of the private health care services becomes less equal in the sense that fewer private hospitals and clinics hold more and more of the share of the total sales. From a cross-industry analysis it is clear that the private hospital sector has the highest concentration rate. Finally, it appears that the market structure of the private hospitals in Greece resembles more closely to an oligopoly rather than a monopolistic competition, since very few firms dominate the market.

    The Cuban power sector faces a need for extensive investment in new generating capacity, under a large number of uncertainties regarding future conditions, including: rate of demand growth, fluctuations in fuel prices, access to imported fuel, and access to investment capital for construction of new power plants and development of fuel import infrastructure. To identify cost effective investment strategies under these uncertainties, a supply and power sector MARKAL model was assembled, following an extensive review of available data on the Cuban power system and resource potentials. Two scenarios were assessed, a business-as-usual (BAU) scenario assuming continued moderate electricity load growth and domestic fuel production growth, and a high growth (HI) scenario assuming rapid electricity demand growth, rapid increase in domestic fuel production, and a transition to market pricing of electricity. Within these two scenarios sets, sensitivity analyses were conducted on a number of variables. The implications of least-cost investment strategies for new capacity builds, investment spending requirements, electricity prices, fuel expenditures, and carbon dioxide emissions for each scenario were assessed. Natural gas was found to be the cost effective fuel for new generation across both scenarios and most sensitivity cases, suggesting that access to natural gas, through increased domestic production and LNG import, is a clear priority for further analysis in the Cuban context.

    Highlights: → This paper establishes a carbon captures and storage (CCS) investment evaluation model. → The model is based on real options theory and solved by the Least Squares Monte Carlo (LSM) method. → China is taken as a case study to evaluate the effects of regulations on CCS investment. → The findings show that the current investment risk of CCS is high, climate policy having the greatest impact on CCS development. -- Abstract: This paper establishes a carbon capture and storage (CCS) investment evaluation model based on real options theory considering uncertainties from the existing thermal power generating cost, carbon price, thermal power with CCS generating cost, and investment in CCS technology deployment. The model aims to evaluate the value of the cost saving effect and amount of CO 2 emission reduction through investing in newly-built thermal power with CCS technology to replace existing thermal power in a given period from the perspective of power generation enterprises. The model is solved by the Least Squares Monte Carlo (LSM) method. Since the model could be used as a policy analysis tool, China is taken as a case study to evaluate the effects of regulations on CCS investment through scenario analysis. The findings show that the current investment risk of CCS is high, climate policy having the greatest impact on CCS development. Thus, there is an important trade off for policy makers between reducing greenhouse gas emissions and protecting the interests of power generation enterprises. The research presented would be useful for CCS technology evaluation and related policy-making.

    The types of structural analysis in the input-output model known are forward and backwards ties. Fertilizer sector is tied forwardly agriculture, agri-business, chemistry, petro-chemistry and glass sector. In addition, it tied backwardly mining, chemistry, petro-chemistry, electricity, gas, water and transportation. The effect of backward tie of fertilizer sector is more important than its effect of the forward ties. In this study, by means of the year of 1979, 1985 and 1990 input-output table of Turkey the own situation of fertilizer industry and the production relation with other sectors of the economy have been tired to explain with forward and backwards ties. According to the result of the research it was determined that in 1990, (u j ) input coefficient of fertilizer sector is 69 %. That is, 69 percent of the product of fertilizer sector was used as an intermediate goods by other sectors. Therefore, 31 percent of goods produced by fertilizer sector was consumed as a final good. In addition, in this year, (w i ) intermediate use coefficient of fertilizer sector is 52 %. (w i ) intermediate use coefficient of fertilizer sector decreased from 1973 to 1990, as a result of this final use coefficient (1-w i ) increased. Refs. 5 (author)

    Alexe, Fl.; Ionescu, M.

    1996-01-01

    At present, generation, transmission and selling of power in Romania is actually a monopoly of RENEL (The Romanian Electricity Authority). Moreover, RENEL covers an important share of the heat required by the great district heat consumers and industry (steam). Medium and long term programs for RENEL restructuring aims at moving the power distribution and selling sectors out of RENEL and at restructuring the generation sector. The present papers focuses mainly on those issues related to power generation sector privatization meant to promote a real competition in the field of power generation. To reach this purpose new regulations are necessary to ensure the access to the power system of various consumers satisfying certain technical requirements. This regards also all the independent power producers of electricity and possibly of thermal power (for instance the cogeneration power plants with less than or close to 50 MW). At the same time new concepts such as 'contracted power' and 'transit (wiring) tax' should be implemented in the near future in the business relations. Competition in this field will lead to the development of power market and the enhancement of power investments. (author). 3 refs

    2016-07-01

    According to The Organisation for Economic Co-operation and Development (OECD), space sector plays a pivotal role in the functioning of modern societies and their economic development. It is in the scope of OECD's International Futures Programme. The global space economy, as defined by the OECD Space Forum, comprises the space industry's core activities in space manufacturing and in satellite operations, plus other consumer activities that have been derived over the years from governmental research and development. In 2013 commercial revenues generated by the space economy amounted to USD 256.2 billion globally that is huge amount of space investment in the world. Recently, Turkey has also entered to the sector and it has growing strategic interest in space. First satellite project was started with a technology transfer from UK by TUBITAK Space Technologies Research Institute in 2001 and it launched to its orbit in 2003. Then RASAT and GÖKTÜRK-2 satellites were developed and launched to their orbits respectively in 2011 and 2012. Today, we have other satellite projects that are going on, too. However, we do not have a mechanism or a model to assess the impacts of those projects. What kind of model can be used to measure the impact of direct public R&D and innovation investments in Turkish space sector? The aim of this study is to develop a model which would be useful for monitoring the performance of R&D and Innovation investments that are conducted through government policies and strategies and so on to give feedback for effective strategy making. When we look at the impact analysis studies in Turkey, we see a few such as TUBITAK (Özçelik and Taymaz, 2008; Erden, 2010; Tandoǧan, 2011), İşkur (World Bank Report, 2013), Ministry of Economy (TTGV, 2013), Development Agencies (İZKA, 2011; Elçi vd., 2011; Pınar, 2014; Meydan, 2014). There is need for a systematic approach to impact analysis. Since there is no data for this study, we would develop a model with

    2004-12-01

    Full Text Available This article deals with different types of language impairment from the perspective of generative grammar. The paper focuses on syntactic deficiencies observed in aphasic and SLI (specific language impairment patients. We show that the observed ungrammatical structures do not appear in a random fashion but can be predicted by that theory of universal sentence structure which posits a strict hierarchy of its constituent parts. The article shows that while the hierarchically lower elements remain unaffected, the higher positions in the hierarchy show various degrees of syntactic impairment. The paper supports the implementation of recent developments in the field of generative grammar with the intention of encouraging further theoretical, experimental and therapeutic research in the field.

    2018-01-01

    In order to improve the capability of particle trapping close to the source plane, theoretical and experimental studies on near-field multiple traps of paraxial acoustic vortices (AVs) with a strengthened acoustic gradient force (AGF) generated by a sector transducer array were conducted. By applying the integration of point source radiation, numerical simulations for the acoustic fields generated by the sector transducer array were conducted and compared with those produced by the circular transducer array. It was proved that strengthened AGFs of near-field multiple AVs with higher peak pressures and smaller vortex radii could be produced by the sector transducer array with a small topological charge. The axial distributions of the equivalent potential gradient indicated that the AGFs of paraxial AVs in the near field were much higher than those in the far field, and the distances at the near-field vortex antinodes were also proved to be the ideal trapping positions with relatively higher AGFs. With the established 8-channel AV generation system, theoretical studies were also verified by the experimental measurements of pressure and phase for AVs with various topological charges. The formation of near-field multiple paraxial AVs was verified by the cross-sectional circular pressure distributions with perfect phase spirals around central pressure nulls, and was also proved by the vortex nodes and antinodes along the center axis. The favorable results demonstrated the feasibility of generating near-field multiple traps of paraxial AVs with strengthened AGF using the sector transducer array, and suggested the potential applications of close-range particle trapping in biomedical engineering.

    2016-12-01

    Full Text Available With the advances in industry and commerce, passengers have become more accepting of environmental sustainability issues; thus, more people now choose to travel by bus. Government administration constitutes an important part of bus transportation services as the government gives the right-of-way to transportation companies allowing them to provide services. When these services are of poor quality, passengers may lodge complaints. The increase in consumer awareness and developments in wireless communication technologies have made it possible for passengers to easily and immediately submit complaints about transportation companies to government institutions, which has brought drastic changes to the supply–demand chain comprised of the public sector, transportation companies, and passengers. This study proposed the use of big data analysis technology including systematized case assignment and data visualization to improve management processes in the public sector and optimize customer complaint services. Taichung City, Taiwan, was selected as the research area. There, the customer complaint management process in public sector was improved, effectively solving such issues as station-skipping, allowing the public sector to fully grasp the service level of transportation companies, improving the sustainability of bus operations, and supporting the sustainable development of the public sector–transportation company–passenger supply chain.

    Full Text Available The article deals with and determines the peculiarities of the investment potential of lands of Ukrainian economic agrarian sector. The author studies the main positives contributing the development of investment for enterprises of agricultural purpose. The reasons that restrain the investment in agriculture are determined. It is emphasized that when using land resources, one should take into account the current specificity of environment in the economic agrarian sector. The article singles out the factors, which form the specificity of development of lease land relations. It is stressed that the important characteristic of lease land relations is their social and economic direction. It is proved that the obligatory condition of a lease agreement has to become the characteristic of a quality state for a land plot. More than a third part of all national income of the country was formed in economic agrarian sector. In particular, 70 % of total amount of retail goods turnover, a third part of main production facilities, a fourth part of population, employed in the Ukrainian economy, was busy working. According to the data of UNO, the potential of Ukrainian lands allows to provide about 100 mln. individuals with foods. To reach this and to renew the present level under current economic conditions one can due to the implementation of essentially new approaches to the organization of agricultural production.

    In this article, the author discusses the analysis of power sector system losses in both the countries which are similar in nature. The design and construction of major power plants, grid substations and transmission lines are constructed on the same pattern. The generation system loss under transmission must not exceed the limit and any loss above this limit could safely be taken as pilferage or theft of energy. The author is of the opinion that socio-economic conditions prevailing in both countries. The author is not in a position to analyse or comment on the causes of non-technical system loss in Pakistan, but he feels that some of the causes could also equally be applicable. (A.B.)

    Putranti, Titi Muswati; Imansyah, Muhammad Handry

    2017-12-01

    The objective of this paper is to evaluate the change of CO2 emission on manufacturing sectors in Indonesia using input-output analysis. The method used supply perspective can measure the impact of an increase in the value added of different productive on manufacturing sectors on total CO2 emission and can identify the productive sectors responsible for the increase in CO2 emission when there is an increase in the value added of the economy. The data used are based on Input-Output Energy Table 1990, 1995 and 2010. The method applied the elasticity of CO2 emission to value added. Using the elasticity approach, one can identify the highest elasticity on manufacturing sector as the change of value added provides high response to CO2 emission. Therefore, policy maker can concentrate on manufacturing sectors with the high response of CO2 emission due to the increase of value added. The approach shows the contribution of the various sectors that deserve more consideration for mitigation policy. Five of highest elasticity of manufacturing sectors of CO2 emission are Spinning & Weaving, Other foods, Tobacco, Wearing apparel, and other fabricated textiles products in 1990. Meanwhile, the most sensitive sectors Petroleum refinery products, Other chemical products, Timber & Wooden Products, Iron & Steel Products and Other non-metallic mineral products in 1995. Two sectors of the 1990 were still in the big ten, i.e. Spinning & weaving and Other foods in 1995 for the most sensitive sectors. The six sectors of 1995 in the ten highest elasticity of CO2 emission on manufacturing which were Plastic products, Other chemical products,Other fabricated metal products, Cement, Iron & steel products, Iron & steel, still existed in 2010 condition. The result of this research shows that there is a change in the most elastic CO2 emission of manufacturing sectors which tends from simple and light manufacturing to be a more complex and heavier manufacturing. Consequently, CO2 emission jumped

    of the industry could be split up into energy intensive subsectors where single production processes dominate the energy consumption, and non-energy intensive subsectors. Ways to reduce the energy consumption in the industrial sector are the use of alternative or improved production or cross cutting technologies and the use of energy saving measures to reduce the demand for useable energy. Based on the analysis within this study, 21 % of the current energy consumption of the industrial sector of the EU and 17 % in Germany could be reduced. Based on the extended understanding of energy efficiency, the model based scenario analysis of the European energy system with the further developed energy system model TIMES PanEU shows that the efficient use of energy at an emission reduction level of 75 % is a slightly increasing primary energy consumption. The primary energy consumption is characterised by a diversified energy carrier and technology mix. Renewable energy sources, nuclear energy and CCS play a key role in the long term. In addition the electricity demand in combination with a strong decarbonisation of the electricity generation is increasing constantly. In the industrial sector the emission reduction is driven by the extended use of electricity, CCS and renewables as well as by the use of improved or alternative process and supply technologies with lower specific energy consumption. Thereby the final energy consumption stays almost on a constant level with increasing importance of electricity and biomass. Both regulatory interventions in the electricity sector and energy saving targets on the primary energy demand lead to higher energy system costs and therewith to a decrease of efficiency based on the extended understanding. The energy demand is reduced stronger than it is efficient and the saving targets lead to the extended use of other resources resulting in totally higher costs. The integrated system analysis in this study points out the interactions

    One of the aspects of socio-economic assessment of development is quantification of the expected requirements on the number of personnel. Predictions are discussed for the period before the year 2005 for solid fuel mining and treatment, gas production and bitumen mining, power and heat generation and also for the production of electricity and heat by nuclear power plants. They are based on an analysis of past development and the present state, on presumed implementation of various concept variants, on the type structure of nuclear power plants, on the rules of the electric power supply system, and also on foreign materials. It is expected that in 2005, nuclear power will employ 15,654 personnel. (M.D.). 4 tabs., 16 refs

    Thermodynamic losses usually take place in machineries used for agricultural activities. Therefore, it is important to identify and quantify the losses in order to devise strategies or policies to reduce them. An exergy analysis is a tool that can identify the losses occurred in any sector. In this study, an analysis has been carried out to estimate energy and exergy consumption of the agricultural sector in Malaysia. Energy and exergy efficiencies have been determined for the devices used in the agricultural sector of Malaysia, where petrol, diesel and fuel oil are used to run the machineries. Energy and exergy flow diagrams for the overall efficiencies of Malaysian agricultural sector are presented as well. The average overall energy and exergy efficiencies of this sector were found to be 22% and 20.728%, respectively, within the period from 1991 to 2009. These figures were found to be lower than those of Norway but higher than Turkey. - Highlights: ► Highest exergy efficiency was found about 20.7% for the year 2007. ► The exergy efficiency of the agro-sector in Malaysia was lower than that of energy efficiency. ► It was also found that this sector of Malaysia is less efficient than Saudi Arabia and Norway. ► Energy and exergy losses were identified through this analysis. ► Part of the losses can be reduced using appropriate technology, management and policy.

    It has been 30 years since the first transformation of a gene into a plant species, and since that time a number of biotechnology products have been developed, with the most important being insect- and herbicide-resistant crops. The development of second-generation products, including nutrient use efficiency and tolerance to important environmental stressors such as drought, has, up to this time, been less successful. This is in part due to the inherent complexities of these traits and in part due to limitations in research infrastructure necessary for public sector researchers to test their best ideas. Here we discuss lessons from previous work in the generation of the first-generation traits, as well as work from our labs and others on identifying genes for nitrogen use efficiency. We then describe some of the issues that have impeded rapid progress in this area. Finally, we propose the type of public sector organization that we feel is necessary to make advances in important second-generation traits such as nitrogen use efficiency. © The Author 2014.

    A physical analysis of some features of the gauge theories with Higgs sectors is made. It is shown that we should assume gauge transformations in the fermion and Higgs sectors to be different (i.e., to have different charges) in order to remove contradictions arising in gauge theories with Higgs sectors. Then, the Higgs mechanism can be interpreted as some mechanism of gauge field shielding. In such a mechanism fermions remain without masses. The conclusion is made that in the standard theory of the development of the Universe, monopoles cannot survive at low temperatures. 15 refs

    In Malaysia, construction sector is essential parts in driving the development of the Malaysian economy. Construction industry is an economic investment and its relationship with economic development is well posited. However, the evaluation on the efficiency of the construction sectors companies listed in Kuala Lumpur Stock Exchange (KLSE) with Data Analysis Envelopment (DEA) model have not been actively studied by the past researchers. Hence the purpose of this study is to examine the financial performance the listed construction sectors companies in Malaysia in the year of 2015. The results of this study show that the efficiency of construction sectors companies can be obtained by using DEA model through ratio analysis which defined as the ratio of total outputs to total inputs. This study is significant because the inefficient companies are identified for potential improvement.

    2015-01-01

    The industrial sector accounts for 70% of the total energy-related CO_2 emissions in China. To gain a better understanding of the changes in carbon intensity in China's industrial sector, this study first utilized logarithmic mean Divisia index (LMDI) decomposition analysis to disentangle the carbon intensity into three influencing factors, including the emission coefficient effect, the energy intensity effect, and the structure effect. Then, the analysis was furthered to explore the contributions of individual industrial sub-sectors to each factor by using an extension of the decomposition method proposed in Choi and Ang (2012). The results indicate that from 1996 to 2012, the energy intensity effect was the dominant factor in reducing carbon intensity, of which chemicals, iron and steel, metal and machinery, and cement and ceramics were the most representative sub-sectors. The structure effect did not show a strong impact on carbon intensity. The emission coefficient effect gradually increased the carbon intensity, mainly due to the expansion of electricity consumption, particularly in the metal and machinery and chemicals sub-sectors. The findings suggest that differentiated policies and measures should be considered for various industrial sub-sectors to maximize the energy efficiency potential. Moreover, readjusting the industrial structure and promoting clean and renewable energy is also urgently required to further reduce carbon intensity in China's industrial sector. - Highlights: • The study analyzed the changes in carbon intensity in China's industrial sector. • An extension of the Divisia index decomposition methodology was utilized. • Energy efficiency improvement was the dominant factor reducing carbon intensity. • The sub-sector contributions to the energy efficiency improvement varied markedly. • Emission coefficient growth can be mainly due to the expansion of electricity.

    2017-01-01

    Today, sustainable energy development is one of key issues on European development agenda. The article describes one of sustainable energy development promoting tool - the eco-labelling scheme for district heating and cooling systems elaborated within the framework of Intelligent Energy for Europe program project “Ecoheat4cities” and partially funded by European Agency for Competitiveness and Innovation. The scheme is based on measured energy and environmental performance data of the district heating and cooling system and considers primary non-renewable energy usage together with the share of renewable energy and carbon dioxide emissions calculated using life-cycle analysis methodology. The “power bonus” approach is used for performance indicators of the heat generated in cogeneration installations. An analysis of a number of Lithuanian district heating companies using elaborated labelling criteria shows positive trends towards fulfilling Lithuania's energy policy goals. The labelling scheme gives opportunity for policy makers and urban planners to compare different heat supply options and decide upon exploiting district heating advantages and benefits for reaching EU energy and environment policy goals. - Highlights: • Overview of Lithuania's district heating sector was performed via main sustainability criteria. • Developing to greener and more efficient state was disclosed via analysis of three years activity results. • Green labelling may help district heating companies to maintain existing and attract new potential consumers.

    The industrial sector is the second largest consumer of energy in Malaysia. In this energy audit, the most important parameters that have been collected are as follows: power rating and operation time of energy-consuming equipments/machineries; fossil fuel and other sources of energy use; production figure; peak and off-peak tariff usage behavior and power factor. These data were then analyzed to investigate the breakdown of end-use equipments/machineries energy use, the peak and off-peak usage behavior, power factor trend and specific energy use. The results of the energy audit showed that the highest electrical energy-using equipment was an electric motor followed by pumps and air compressors. The specific energy use has been estimated and compared with four Indonesian industries and it was found that three Malaysian industries were more efficient than the Indonesian counterpart. The study also found that about 64% electrical energy was used in peak hours by the industries and the average power factor ranged from 0.88 to 0.92. The study also estimated energy and bill savings using highly efficient electrical motors along with the payback period. (author)

  2. Consistent economic cross-sectoral climate change impact scenario analysis: Method and application to Austria

    Full Text Available Climate change triggers manifold impacts at the national to local level, which in turn have various economy-wide implications (e.g. on welfare, employment, or tax revenues. In its response, society needs to prioritize which of these impacts to address and what share of resources to spend on each respective adaptation. A prerequisite to achieving that end is an economic impact analysis that is consistent across sectors and acknowledges intersectoral and economy-wide feedback effects. Traditional Integrated Assessment Models (IAMs are usually operating at a level too aggregated for this end, while bottom-up impact models most often are not fully comprehensive, focusing on only a subset of climate sensitive sectors and/or a subset of climate change impact chains. Thus, we develop here an approach which applies climate and socioeconomic scenario analysis, harmonized economic costing, and sector explicit bandwidth analysis in a coupled framework of eleven (biophysical impact assessment models and a uniform multi-sectoral computable general equilibrium model. In applying this approach to the alpine country of Austria, we find that macroeconomic feedbacks can magnify sectoral climate damages up to fourfold, or that by mid-century costs of climate change clearly outweigh benefits, with net costs rising two- to fourfold above current damage cost levels. The resulting specific impact information – differentiated by climate and economic drivers – can support sector-specific adaptation as well as adaptive capacity building. Keywords: climate impact, local impact, economic evaluation, adaptation

  3. A Novel Water Supply Network Sectorization Methodology Based on a Complete Economic Analysis, Including Uncertainties

    Directory of Open Access Journals (Sweden)

    Enrique Campbell

    2016-04-01

    Full Text Available The core idea behind sectorization of Water Supply Networks (WSNs is to establish areas partially isolated from the rest of the network to improve operational control. Besides the benefits associated with sectorization, some drawbacks must be taken into consideration by water operators: the economic investment associated with both boundary valves and flowmeters and the reduction of both pressure and system resilience. The target of sectorization is to properly balance these negative and positive aspects. Sectorization methodologies addressing the economic aspects mainly consider costs of valves and flowmeters and of energy, and the benefits in terms of water saving linked to pressure reduction. However, sectorization entails other benefits, such as the reduction of domestic consumption, the reduction of burst frequency and the enhanced capacity to detect and intervene over future leakage events. We implement a development proposed by the International Water Association (IWA to estimate the aforementioned benefits. Such a development is integrated in a novel sectorization methodology based on a social network community detection algorithm, combined with a genetic algorithm optimization method and Monte Carlo simulation. The methodology is implemented over a fraction of the WSN of Managua city, capital of Nicaragua, generating a net benefit of 25,572 $/year.

    Highlights: • We analyzed the factors impacting China’s emissions from a sectoral perspective. • Sector-specific policies and measures for emissions mitigation were evaluated. • Economic growth dominantly increased the emissions in the economic sectors. • Energy intensity decrease primarily reduced the emissions in the economic sectors. • Residential emissions growth was mainly driven by increase in per-capita energy use. - Abstract: In order to better understand sectoral greenhouse gas (GHG) emissions in China, this study utilized a logarithmic mean Divisia index (LMDI) decomposition analysis to study emission changes from a sectoral perspective. Based on the decomposition results, recently implemented policies and measures for emissions mitigation in China were evaluated. The results show that for the economic sectors, economic growth was the dominant factor in increasing emissions from 1996 to 2011, whereas the decline in energy intensity was primarily responsible for the emission decrease. As a result of the expansion of industrial development, economic structure change also contributed to growth in emissions. For the residential sector, increased emissions were primarily driven by an increase in per-capita energy use, which is partially confirmed by population migration. For all sectors, the shift in energy mix and variation in emission coefficient only contributed marginally to the emissions changes. The decomposition results imply that energy efficiency policy in China has been successful during the past decade, i.e., Top 1000 Priorities, Ten-Key Projects programs, the establishment of fuel consumption limits and vehicle emission standards, and encouragement of efficient appliances. Moreover, the results also indicate that readjusting economic structure and promoting clean and renewable energy is urgently required in order to further mitigate emissions in China

    2014-11-01

    Full Text Available The Nigerian Gas Master-Plan, Investment Opportunities, Challenges, Issues Affecting Power Sector: an Analysis. The objective of this article is to contribute towards understanding of the Nigerian Gas Master Plan (NGMP/Plan and its bifurcations with key socio-economic development factors. I applied the method of discourse to bring to being some points that have hitherto been unknown about the Master-plan and its inter-relationships and bifurcations. Elaborated here are the spectacular gains that have accrued to the Latin American country, Trinidad and Tobago, from its recent development of natural gas resources. This was considered suitable and significant here for highlighting that if such spectacular achievements could be realized from Trinidad and Tobago’s relatively smaller gas deposit (15.3 tcf, probable reserves (8.4 tcf, possible reserves (6.2 tcf would be by far greater considering Nigeria’s larger natural gas reserves (184 tcf wealth as earlier stated. I show that the Plan is well designed relevant to addressing Nigeria’s current development needs generally. It presents potentials for stimulating Nigeria’s economic growth by harnessing the country’s abundant natural gas reserves. The Plan enumerates/ elaborates huge investment opportunities. Some challenges likely to be faced in the implementation/management of the Plan are already being surmounted as recent reports show that some of its key investments have been realized and the required infrastructure are being provided. Regarding the issues in the Master-plan that are likely to affect and are affecting Nigeria’s power sector development, I reckon that they are mostly positive factors due to the way the plan promises to stimulate electricity generation in our country.

    Full Text Available Banking sector is an important development factor of the total financial and economic system. Number of banks and dispersion of their individual shares defines competitive structure of banking sector, manifested by its concentration. Market concentration may be presented as a function of a number of enterprises competing in a market and their individual comparative market shares. Concentration analysis is significant with regard to the fact that the level of concentration demonstrates relations among competitors in a market, as well as influence each competitor has on consumers, branch and economy as a whole. Starting from 2008 crisis, domino effect of which hit banking sector and has had a huge impact on it, authors of this paper aimed at establishing a level of market concentration of the banking sector in Serbia and countries in the region in 2015 by application of a large number of market concentration indicators.

    2010-01-01

    Energy-related CO 2 emissions embodied in international trade have been widely studied by researchers using the input-output analysis framework. These studies are often conducted at a specific level of sector aggregation and the choice made to a large extent is dictated by economic and energy data availability. We investigate analytically the possible effects of sector aggregation on the study results. We conduct empirical studies using the data of China and Singapore where energy-related CO 2 emissions embodied in their exports are estimated at different levels of sector aggregation. A finding from the studies is that levels around 40 sectors appear to be sufficient to capture the overall share of emissions embodied in a country's exports. Another finding is that in approximating the 'ideal' situation the hybrid data treatment approach produces better results than the uniformly distributed data treatment approach. Other findings and some recommendations are also presented. (author)

    Full Text Available The past few years have witnessed many storms in the Tourism sector. Under the influence of an extremely volatile world economy (financial crisis, commodity and oil price rises, sharp exchange rate fluctuations, increase terrorism acts in several region with tourism potential Tourism demand slowed significantly. Yet, despite the current difficulties, the Tourism sector remains a critical economic sector worldwide and one that provides significant potential for economic growth and development internationally. A growing national Tourism sector contributes to raises national income, employment, and can improve a country's balance of payments. The sector is thus an important driver of growth and prosperity and,  within developing countries, it can play a leading role in poverty reduction. Despite the overall importance of developing the Tourism sector, many obstacles at the national level continue to hinder its development. This analysis aims to serve two purposes. First, we intend to provide useful comparative information for making decisions related to business and tourism development. Second, and more importantly, we hope that the analysis provides an opportunity for the Tourism industry to highlight the obstacles to Tourism competitiveness.

    2016-06-01

    Full Text Available Purpose - The purpose of this paper is to examine the determinants of banking sector profitability in Egypt to shed light on the most influential variables that have a significant impact on the performance of this vital sector. Design/methodology/approach - The analysis includes a time series model of quarterly data from 2004 to 2014. The model utilizes Cointegration technique to investigate the long-run relationship between the return on equity as a proxy for bank profitability and several bank-specific variables including liquidity, capital adequacy, and percentage of non-performing loans. In addition, Vector Error Correction Model (VECM is utilized to explore the short-run dynamics of the model and the speed of adjustment to reach the long-run equilibrium. Findings - The main findings of this work show that banking sector profitability is inversely related to capital adequacy, the percentage of loan provisions and the ratio of deposits to total assets. On the other hand, it is positively related to the size of the banking sector which implies that the banking sector exhibits economies of scale. Research limitations/implications - The implications of this work is that it helps reveal the major factors affecting bank performance in the short-run and long-run, and hence provide bank managers and monetary policy makers with beneficial insights on how to enhance bank performance. Since the banking sector represents one of the main engines of financing investment, enhancing the efficiency of this sector would contribute to economic growth and prosperity Originality/value - The Vector error correction model showed that about 4% of the disequilibrium is corrected each quarter to reach the long run equilibrium. In addition, all bank specific variables were found to affect profitability in the long-run only. This study would serve as a base that further work on Egyptian banking sector profitability can build on by incorporating more variables in the

    Energy efficiency and its implications for a decrease in carbon dioxide emissions have been a main force behind the current debate on energy issues. Until now, the attention of policy-makers and scientists has been mainly focused on the industrial and residential sectors, although the transport sector has gained relevance in the fast few years. The service sector, on the other hand, has remained at the bottom of the priority list. The main goal of this paper is to explore patterns of energy consumption and energy intensity in the Dutch service sector in the last 15 years. This paper is divided into two parts. The first part deals with developments for the whole sector, including a decomposition analysis, and the second part analyses sectoral developments for five sub-sectors: Wholesale and retail trade, hotels and restaurants; Financial institutes; Real estate renting and business activities; Education and Hospitals. At the aggregate level we have found a strong increase in energy consumption, especially in electricity. Furthermore, we found no evidence of significant decrease in energy intensity in the last decade. Furthermore, the decomposition analysis showed that (a) the activity effect (value added) has been the main driving force behind the increase of energy consumption of the service sector, (b) an increase in labour intensity has also boosted energy consumption and (c) energy intensity (in terms of energy per employee) did not have a significant role on decreasing energy use. At the subsectoral level the picture is blurred, especially due to the lack of good quality data. With exception of the sector Real estate renting and business activities which showed a decrease in energy intensity of about 20% between 1993 and 1999, the decrease in energy intensity is quite low. Hence, the results point towards a failure of actual energy policies to address the service sector. This is in contrast to the fact that, due to the high share of electricity consumption and

    The industrial sector was the third-largest source of direct U.S. greenhouse gas (GHG) emissions in 2014 behind electricity generation and transportation and accounted for roughly 20% of total emissions (EPA 2016). The Energy Information Administration (EIA) projects that total U.S. energy consumption will grow to about 108 exajoules (1 EJ = 1018 J) or 102 quads (1 quad = 1015 British thermal units) in 2025, with nearly all of the growth coming from the industrial sector (DOE 2015b). Energy consumption in the industrial sector is forecast to increase to 39.5 EJ (37.4 quads)—a 22% increase, exceeding 36% of total energy consumption in the United States. Therefore, it is imperative that industrial GHG emissions be considered in any strategy intent on achieving deep decarbonization of the energy sector as a whole. It is important to note that unlike the transportation sector and electrical grid, energy use by industry often involves direct conversion of primary energy sources to thermal and electrical energy at the point of consumption. About 52% of U.S. industrial direct GHG emissions are the result of fuel combustion (EPA 2016) to produce hot gases and steam for process heating, process reactions, and process evaporation, concentration, and drying. The heterogeneity and variations in scale of U.S. industry and the complexity of modern industrial firms’ global supply chains are among the sector’s unique challenges to minimizing its GHG emissions. A combination of varied strategies—such as energy efficiency, material efficiency, and switching to low-carbon fuels—can help reduce absolute industrial GHG emissions. This report provides a complement to process-efficiency improvement to consider how clean energy delivery and use by industry could reduce GHG emissions. Specifically, it considers the possibility of replacing fossil-fuel combustion in industry with nuclear (specifically small modular reactors [SMRs]), solar thermal (referred to

    We reviewed applications of big data analysis of healthcare and social services in developed countries, and subsequently devised a framework for such an analysis in Korea. We reviewed the status of implementing big data analysis of health care and social services in developed countries, and strategies used by the Ministry of Health and Welfare of Korea (Government 3.0). We formulated a conceptual framework of big data in the healthcare and social service sectors at the national level. As a specific case, we designed a process and method of social big data analysis on suicide buzz. Developed countries (e.g., the United States, the UK, Singapore, Australia, and even OECD and EU) are emphasizing the potential of big data, and using it as a tool to solve their long-standing problems. Big data strategies for the healthcare and social service sectors were formulated based on an ICT-based policy of current government and the strategic goals of the Ministry of Health and Welfare. We suggest a framework of big data analysis in the healthcare and welfare service sectors separately and assigned them tentative names: 'health risk analysis center' and 'integrated social welfare service network'. A framework of social big data analysis is presented by applying it to the prevention and proactive detection of suicide in Korea. There are some concerns with the utilization of big data in the healthcare and social welfare sectors. Thus, research on these issues must be conducted so that sophisticated and practical solutions can be reached.

    2016-01-01

    Full Text Available The goal of this article is the analysis of influence of market concentration in selected areas of public procurement on chosen parameters of public procurement in years 2007 and 2011. Five concentration ratios and five parameters of contracts are calculated for each of five chosen areas of public tenders in 2007 and 2011. After this task, the correlation analysis between concentration ratios and parameters of contracts is done for finding out mutual relation between these two variables. Correlation analysis is then compared with four created hypotheses about the relationship between market concentration and parameters of public procurement The results of the analysis are surprising, because in most cases, the stated hypotheses were rejected, meaning that the correlations between the parameters of public procurement and market concentration were different than this study predicted based on economic theory. The possible reasons for this result, discussed in the article, are corruption and also poor quality of data from Information system of public procurement administered by the Ministry for Regional Development of Czech Republic.

    This study challenges the efficient market hypothesis, relying on the Dow Jones sector Exchange-Traded Fund (ETF) indices. For this purpose, we use the generalized Hurst exponent and multifractal detrended fluctuation analysis (MF-DFA) methods, using daily data over the timespan from 2000 to 2015. We compare the sector ETF indices in terms of market efficiency between short- and long-run horizons, small and large fluctuations, and before and after the global financial crisis (GFC). Our findings can be summarized as follows. First, there is clear evidence that the sector ETF markets are multifractal in nature. We also find a crossover in the multifractality of sector ETF market dynamics. Second, the utilities and consumer goods sector ETF markets are more efficient compared with the financial and telecommunications sector ETF markets, in terms of price prediction. Third, there are noteworthy discrepancies in terms of market efficiency, between the short- and long-term horizons. Fourth, the ETF market efficiency is considerably diminished after the global financial crisis.

  3. The mineral sector and economic development in Ghana: A computable general equilibrium analysis

    Science.gov (United States)

    Addy, Samuel N.

    A computable general equilibrium model (CGE) model is formulated for conducting mineral policy analysis in the context of national economic development for Ghana. The model, called GHANAMIN, places strong emphasis on production, trade, and investment. It can be used to examine both micro and macro economic impacts of policies associated with mineral investment, taxation, and terms of trade changes, as well as mineral sector performance impacts due to technological change or the discovery of new deposits. Its economywide structure enables the study of broader development policy with a focus on individual or multiple sectors, simultaneously. After going through a period of contraction for about two decades, mining in Ghana has rebounded significantly and is currently the main foreign exchange earner. Gold alone contributed 44.7 percent of 1994 total export earnings. GHANAMIN is used to investigate the economywide impacts of mineral tax policies, world market mineral prices changes, mining investment, and increased mineral exports. It is also used for identifying key sectors for economic development. Various simulations were undertaken with the following results: Recently implemented mineral tax policies are welfare increasing, but have an accompanying decrease in the output of other export sectors. World mineral price rises stimulate an increase in real GDP; however, this increase is less than real GDP decreases associated with price declines. Investment in the non-gold mining sector increases real GDP more than investment in gold mining, because of the former's stronger linkages to the rest of the economy. Increased mineral exports are very beneficial to the overall economy. Foreign direct investment (FDI) in mining increases welfare more so than domestic capital, which is very limited. Mining investment and the increased mineral exports since 1986 have contributed significantly to the country's economic recovery, with gold mining accounting for 95 percent of the

    The full extent of the global burden of surgical disease is largely unknown; however, the scope of the problem is thought to be large. Despite the substantial burden of surgical disease, surgical services are inaccessible to many of those who need them most. There are disparities between public and private sectors in South Africa, which compounds inequitable access to surgical care. This study involved a descriptive analysis of surgical resources and included the total number of hospitals, hospital beds, surgical beds, general surgeons (specialist and nonspecialist), and the number of functional operating theatres in South Africa. A comparison was performed between the public sector resources per uninsured population and private sector resources per insured population. Hospitals were contacted during the period 01 October 2014 to 31 December 2014. Surgical resources were concentrated in metropolitan areas of urban provinces. There were striking differences between sectors when a comparison was made between patients with and without health insurance. Private resources were comparable to those available in high income countries (HICs) and were accessible to only 16% of South Africans. Improving access to surgical services in lower middle income countries (LMICs) requires addressing gaps between the public and private sector regarding infrastructure, personnel, as well as equipment. South Africa is unique in that although it is classified as an upper middle income country (UMIC), it comprises of two sectors; a public sector which has resources similar to other LMICs, and a private sector which has resources similar to HICs. These data identified disparities between geographic regions which may be contributing to ongoing inequity in South Africa, and by doing so allows for evidence-based planning towards improving surgical infrastructure and workforce.

  5. Entropy Generation Analysis of Desalination Technologies

    John H. Lienhard V

    2011-09-01

    Full Text Available Increasing global demand for fresh water is driving the development and implementation of a wide variety of seawater desalination technologies. Entropy generation analysis, and specifically, Second Law efficiency, is an important tool for illustrating the influence of irreversibilities within a system on the required energy input. When defining Second Law efficiency, the useful exergy output of the system must be properly defined. For desalination systems, this is the minimum least work of separation required to extract a unit of water from a feed stream of a given salinity. In order to evaluate the Second Law efficiency, entropy generation mechanisms present in a wide range of desalination processes are analyzed. In particular, entropy generated in the run down to equilibrium of discharge streams must be considered. Physical models are applied to estimate the magnitude of entropy generation by component and individual processes. These formulations are applied to calculate the total entropy generation in several desalination systems including multiple effect distillation, multistage flash, membrane distillation, mechanical vapor compression, reverse osmosis, and humidification-dehumidification. Within each technology, the relative importance of each source of entropy generation is discussed in order to determine which should be the target of entropy generation minimization. As given here, the correct application of Second Law efficiency shows which systems operate closest to the reversible limit and helps to indicate which systems have the greatest potential for improvement.

    Pijawka, K.D.

    1984-01-01

    One of the major issues in community impact management is the gap between revenues generated by energy projects and expenditures for public facilities and services because of project-induced growth. Of issue is the experience of communities experiencing rapid growth where project revenues are not generated until operations commence and yet, considerable investments are needed to accommodate growth during the construction phase. Such revenue imbalances have resulted in communities demanding ''up-front'' capital investments or revenue prior to and during construction. However, with the construction and operation of nuclear facilities, the few available studies have found substantial revenue gains allocated to local jurisdiction and little adverse expenditure effects. The analyses of twelve nuclear stations found that the demand for new and expanded public facilities and the social services attributable to the plants were generally small, that adverse impacts were controllable and mitigatable, and that utility revenue payments varied substantially amount the host areas

    Mulder, P. [International Institute for Applied Systems Analysis, Laxenburg (Austria); De Groot, H.L.F. [Faculty of Economics and Business Administration, Vrije Universiteit, Amsterdam (Netherlands)

    2004-07-01

    This paper provides an empirical analysis of decoupling economic growth and energy use and its various determinants by exploring trends in energy- and labour productivity across 10 manufacturing sectors and 14 OECD countries for the period 1970-1997. We explicitly aim to trace back aggregate developments in the manufacturing sector to developments at the level of individual subsectors. A cross-country decomposition analysis reveals that in some countries structural changes contributed considerably to aggregate manufacturing energy-productivity growth and, hence, to decoupling, while in other countries they partly offset energy-efficiency improvements. In contrast, structural changes only play a minor role in explaining aggregate manufacturing labour-productivity developments. Furthermore, we find labour-productivity growth to be higher on average than energy-productivity growth. Over time, this bias towards labour-productivity growth is increasing in the aggregate manufacturing sector, while it is decreasing in most manufacturing subsectors.

    2017-12-01

    The objective of this article is to analyse the structure of the Spanish eating-out sector from an economic point of view, and more specifically, from the supply perspective. This aspect has been studied less than the demand side, almost certainly due to the gaps which exist in available official statistics in Spain, and which have been filled basically with consumer surveys. For this reason, focus is also placed on the economic relevance of the sector and attention is drawn to the serious shortcomings regarding official statistics in this domain, in contrast to the priority that hotel industry statistics have traditionally received in Spain. Based on official statistics, a descriptive analysis was carried out, focused mainly, though not exclusively, on diverse structural aspects of the sector. Special emphasis was placed on issues such as business demography (for instance, number and types of enterprises, survival rates, size distribution, and age structure), market concentration and structure of costs. Among other conclusions, the analysis allowed us to conclude that: part of the sector is more concentrated than it may at first appear to be; the dual structure of the sector described by the literature in relation to other countries is also present in the Spanish case; and the impact of ICTs (Information and Communication Technologies) on the sector are, and will foreseeably continue to be, particularly relevant. The main conclusion of this study refers to the fact that consumers have gained prominence in their contribution to shaping the structure of the sector. Copyright © 2017 Elsevier Ltd.

    Full Text Available This study focuses on the characteristics of the information database of the OECD structural business statistics in the analysis of markets of goods and services, and macroeconomic trends. The system of indicators of structural statistics is presented in OECD publications and on-line access to a wide range of users. Collected data sources generated by the OECD offices are based on the national statistical offices of country-members, Russia and the BRICS. Data on the development of economic sectors are calculated according to the methodology of individual countries, regional and international standards: annual national accounts of countries, annual industry and business surveys, methodology of short-term indicators, statistics of international trade in goods. Data are aggregated on the basis of complex indicators statements of the enterprises' questionnaire and business surveys. Information system of structural statistics which is available and continuously updated, has certain features. It is composed of several subsystems: Structural Statistics on Industry and Services, EU entrepreneurship statistics, Indicators of Industry and Services, International Trade in Commodities Statistics. The grouping of industries is based on the International standard industrial classification of all economic activities (ISIC. Classification of foreign trade flows is made in accordance with the Harmonized system of description and coding of goods. The structural statistics databases comprise four classes of industries' grouping according to the technology intensity. The paper discusses the main reasons for the non-comparability of data in the subsystems in certain time intervals.

    2015-01-01

    Residential sector is the core among the energy demand sectors in Pakistan. Currently, various techniques are being used worldwide to assess future energy demands including integrated system modeling (ISM). Therefore, the current study is focused on implementation of ISM approach for future energy demand analysis of Pakistan's residential sector in terms of increase in population, rapid urbanization, household size and type, and increase/decrease in GDP. A detailed business-as-usual (BAU) model is formulated in TIMES energy modeling framework using different factors like growth in future energy services, end-use technology characterization, and restricted fuel supplies. Additionally, the developed model is capable to compare the projected energy demand under different scenarios e.g. strong economy, weak economy and energy efficiency. The implementation of ISM proved a viable approach to predict the future energy demands of Pakistan's residential sector. Furthermore, the analysis shows that the energy consumption in the residential sector would be 46.5 Mtoe (Million Ton of Oil Equivalent) in 2040 compared to 23 Mtoe of the base year (2007) along with 600% increase in electricity demands. The study further maps the potential residential energy policies to congregate the future demands. (author)

    2015-07-01

    Full Text Available This paper comprises an assessment of the Romanian health financing policy and a detailed analysis of income and expenditure trends over the past seven years. The current situation of the health system is evaluated by reviewing the existing health legislation and documents on public health policies from Romania and from abroad, by analyzing the official statistics (the Romanian Yearbook of Health Statistics, Who database and by performing a healthcare system financial analysis. Although the financial efforts of the Romanian state to support the health system have increased, almost all the incomes and expenditures of the health care system having recorded significant increases, the population perception on health services worsened. Financing the health system continues to be inadequate and used in an ineffective way. Health is an essential component of well-being with major socio-economic implications. The organization and functioning of the health system depends on ensuring adequate funding. Romania must develop its health strategy in the context of European Union policies. These policies are based on values and principles such as promoting universal protection against financial risk, promoting a more equitable distribution of the financing burden, promoting equitable provision and use of services relative to need, improving the transparency and accountability of the system to the public, promoting quality and efficiency in service delivery, improving administrative efficiency, while ensuring the financial sustainability of the health system. In this context, in order to support a financially sustainable and high performing health system, the paper includes recommendations for increasing the public incomes in the health insurance system and options to streamline the healthcare services and expenses in the future.

    Adequate power supply is an unavoidable prerequisite to any nation's development, and electricity generation, transmission and distribution are capital-intensive requiring huge resources for both funds and capacity. In Nigeria where funds are available and has an estimated of 176 trillion cubic feet of proven natural gas reserves, giving the country one of the top ten natural gas endowments in Africa. Natural gas is a natural occurring gaseous mixture of hydrocarbons gases found in underground reservoirs. It consists mainly of methane (70% - 95%). With small percentage of ethane, butane and other heavier hydrocarbons with some impurities such as water vapour, etc.

    1965-02-15

    The finite electrode size effects on the performance of an infinitely long MHD power generation duct are calculated by means of conformal mapping. The general conformal transformation is deduced and applied in a graphic way. The analysis includes variations in the segmentation degree, the Hall parameter of the gas and the electrode/insulator length ratio as well as the influence of the external circuitry and loading. A general criterion for a minimum of the generator internal resistance is given. The same criterion gives the conditions for the occurrence of internal current leakage between adjacent electrodes. It is also shown that the highest power output at a prescribed efficiency is always obtained when the current is made to flow between exactly opposed electrodes. Curves are presented showing the power-efficiency relations and other generator properties as depending on the segmentation degree and the Hall parameter in the cases of axial and transverse power extraction. The implications of limiting the current to flow between a finite number of identical electrodes are introduced and combined with the condition for current flow between opposed electrodes. The characteristics of generators with one or a few external loads can then be determined completely and examples are given in a table. It is shown that the performance of such generators must not necessarily be inferior to that of segmented generators with many independent loads. However, the problems of channel end losses and off-design loading have not been taken into consideration.

    International Nuclear Information System (INIS)

    Ribeiro, Maria de Fátima dos Santos; Raiher, Augusta Pelinski

    2013-01-01

    The State of Paraná contributes significantly for the Brazilian production of sugar cane, ethanol, soybeans and pigs. In addition to the current production of ethanol, the State has a huge potential for electricity, biodiesel and biogas production. This paper presents an overview of the current situation regarding energy generation from the agricultural sector in the State, an assessment of the potentialities of energy generation from sugar cane residues and pig agricultural chains, as well as an analysis of the socioeconomic factors underlying the availability of feedstock for biodiesel production. This study has shown that it is possible to expand the energy supply in the State using residual biomass from the sugar cane and pig production. On the other side, the biodiesel production increase in the State will depend on the expansion in the consumption of products that use the cake as raw material; the increase in the feedstock availability other than canola, castor beans and sunflower; the increase of the number of family farmers as feedstock providers, so as to ensure access for biodiesel producers to the Social Fuel Stamp. - Highlights: • Potentialities of energy generation from agriculture at Paraná State were assessed. • Energy offer from the sugar cane sector will triple if residual biomass is used. • The use of pig production wastes can increase energy offer up to 103 GW h. • Paraná produces 25% of oil seeds and only 3% of the biodiesel in Brazil. • Economic factors explaining the low share of biodiesel production are pointed out

    2008-09-12

    This report summarizes the results and the assumptions used in an analysis of the potential “lost efficiency opportunities” in the buildings sector. These targets of opportunity are those end-uses, applications, practices, and portions of the buildings market which are not currently being addressed, or addressed fully, by the Building Technologies Program (BTP) due to lack of resources. The lost opportunities, while a significant increase in effort and impact in the buildings sector, still represent only a small portion of the full technical potential for energy efficiency in buildings.

    2015-01-01

    The process of energy conservation and emission reduction in China requires the specific and accurate evaluation of the energy efficiency of the industry sector because this sector accounts for 70 percent of China's total energy consumption. Previous studies have used a “black box” DEA (data envelopment analysis) model to obtain the energy efficiency without considering the inner structure of the industry sector. However, differences in the properties of energy utilization (final consumption or intermediate conversion) in different industry departments may lead to bias in energy efficiency measures under such “black box” evaluation structures. Using the network DEA model and efficiency decomposition technique, this study proposes an adjusted energy efficiency evaluation model that can characterize the inner structure and associated energy utilization properties of the industry sector so as to avoid evaluation bias. By separating the energy-producing department and energy-consuming department, this adjusted evaluation model was then applied to evaluate the energy efficiency of China's provincial industry sector. - Highlights: • An adjusted network DEA (data envelopment analysis) model for energy efficiency evaluation is proposed. • The inner structure of industry sector is taken into account for energy efficiency evaluation. • Energy final consumption and energy intermediate conversion processes are separately modeled. • China's provincial industry energy efficiency is measured through the adjusted model.

    This paper models and estimates electricity demand by the Kuwaiti commercial sector, using an error correction model. It also simulates the estimated model under three scenarios and presents an analysis of the results. The empirical results indicate that short- and long-run electricity consumption and the level of economic activity are interrelated. The forecasts show that electricity consumption varies directly with economic growth. They also suggest that an increase of 100 per cent in nominal electricity prices will lead to a reduction in commercial sector electricity demand of 45 per cent by the year 2010. The simulation of the model under the different scenarios demonstrates that the potential for energy conservation exists in the commercial sector

    Full Text Available Transportation Build-Operate-Transfer financing projects have larger payment risks and failure possibilities than other financing projects, and these factors are essential to financing scenarios. The changes of financing scenarios not only affect private sectors' financing process but the conflict between private sectors and banks. This study broadly reviews relevant factors affecting BOT financing strategies, interviews relevant experts and then uses scenario analysis to design a questionnaire to find out the most important factors affecting BOT financing. The findings of this study are four major factors affecting public and private financing scenarios. In this paper, we also propose some suggestions as possible complements to public and private sector financing strategies.

    2014-01-01

    Full Text Available We conduct a study of the secondary and tertiary sectors with the goal of highlighting the relative im-portance of services in the Mexican economy. We consider a time series analysis approach designed to identify the stochastic nature of the series, as well as to define their long-run and-short run relationships with Gross Domestic Product (GDP. The results of cointegration tests suggest that, for the most part, activities in the secondary and tertiary sectors share a common trend with GDP. Interestingly, the long-run elasticities of GDP with respect to services are on average larger than those with respect to secondary activities. Common cycle tests results identify the existence of common cycles between GDP and the disaggregated sectors, as well as with manufacturing, commerce, real estate and transportation. In this case, the short-run elasticities of secondary activities are on average larger than those corresponding to services.

    2015-12-01

    Full Text Available The development of the fishery sector represents one of the European Union’s priorities due to the positive impact it has on food security and to its potential to ensure nutritious and quality food at an affordable price as compared to other animal-origin resources. The Community policy in the fishery sector focuses on reducing the Community market dependence on imports and on the sustainable development of business in this domain. Romania aligned with the Community policies and, therefore, important funds were allocated to the national fishery sector. The diversified natural resources, the possibility to use friendly technologies, the qualified staff, the tradition in the domain, and the existence of a number of niche markets all represent motivations for the development of the Romanian fishery sector. The present paper proposes an analysis of the Romanian fishery production and of the European financing effects on the specialized companies. Despite the fact that there have been important resources allocated to the sector and there is a slight positive evolution, the absorption of funds was difficult. The results of the investment may be observed after a long period of time, this is why Romania is still dependent on fishery product imports. Aquaculture represents the main segment towards which the European funds were directed, including in our country, thus providing the greatest part of the income and employment in the domain.

    2010-12-01

    Full Text Available The goal of this study is to make a comparative analysis of innovation aspect evidence among construction and multi-sector companies. Descriptive research was done through a content analysis of administration reports from 2005 to 2007. From the researched material, 14 aspects of innovations were extracted, which offer the basis to the content analysis. Two non-probability samples were developed, the first consisting of 22 multi-sector businesses, within 18 economic sectors, which comprises the companies in the comparison. Aspects of innovation found in this group of companies were compared to those stated in the reports of the administration of the 34 construction companies with open capital, which comprise the second sample. The survey results show that the evidence of innovation aspects are different in construction companies when compared to the administration reports of multi-sector business of 2005, 2006 and 2007. The construction companies state fewer innovation aspects in the administration reports than multisector companies in the analyzed period. The conclusion is that while construction companies can be considered fairly innovative, multi-sectorial companies present more innovations on average.

    Philippus C. Cloete

    2014-10-01

    Research purpose: The purpose of this article is to put into context the relative economic contribution of the wildlife ranching sector, as opposed to other land-use options in South Africa. Motivation for the study: Growth in the wildlife ranching sector at the cost of other traditional farming practices resulted in disagreements amongst various role players about the impact thereof on the national economy. The controversy can most probably be explained by different beliefs, coupled with the lack of a proper understanding and quantification of the wildlife ranching sector’s contribution toward the economy. Research methodology: The study employed a Social Accounting Matrix-based Leontief multiplier analysis for South Africa. Main findings: Results from the multiplier analysis revealed that developments within the wildlife ranching sector are likely to make a relatively more superior contribution towards the economy, especially when compared to similar land-use options such as extensive livestock production. Practical/managerial implications: It has been acknowledged by both academia and private sector that a major need exists for more research on the South African wildlife ranching industry, specifically looking at issues such as the industries, economic and social contributions, potentials and constraints. The research, therefore, contributes toward the depth of economic information and research regarding the South African wildlife sector. Contribution/value added: The research provides valuable information in dealing with the ‘popular belief’, especially amongst some of South Africa’s decision makers, namely, that growth in the wildlife ranching sector is not or does not have the ability to contribute significantly toward economic and socioeconomic factors.

  12. Thermal Properties of Biochars Derived from Waste Biomass Generated by Agricultural and Forestry Sectors

    2017-04-01

    Full Text Available Waste residues produced by agricultural and forestry industries can generate energy and are regarded as a promising source of sustainable fuels. Pyrolysis, where waste biomass is heated under low-oxygen conditions, has recently attracted attention as a means to add value to these residues. The material is carbonized and yields a solid product known as biochar. In this study, eight types of biomass were evaluated for their suitability as raw material to produce biochar. Material was pyrolyzed at either 350 °C or 500 °C and changes in ash content, volatile solids, fixed carbon, higher heating value (HHV and yield were assessed. For pyrolysis at 350 °C, significant correlations (p < 0.01 between the biochars’ ash and fixed carbon content and their HHVs were observed. Masson pine wood and Chinese fir wood biochars pyrolyzed at 350 °C and the bamboo sawdust biochar pyrolyzed at 500 °C were suitable for direct use in fuel applications, as reflected by their higher HHVs, higher energy density, greater fixed carbon and lower ash contents. Rice straw was a poor substrate as the resultant biochar contained less than 60% fixed carbon and a relatively low HHV. Of the suitable residues, carbonization via pyrolysis is a promising technology to add value to pecan shells and Miscanthus.

  13. Combustion efficiency: Greenhouse gas emission reductions from the power generation sector

    1993-12-31

    Concern for the possibility of an enhanced greenhouse effect and global climate change (GCC) has often been associated with energy use in general, and fossil fuel combustion in particular, because of associated emissions of CO{sub 2} and other greenhouse gases (GHG). Therefore, energy policies play a significant role in determining greenhouse gas emissions. The generation of electricity and power from more efficient fossil energy technologies provides an opportunity to significantly lower GHG emissions, together with other pollutants. The U.S. government oversees a broad-based program to facilitate the development, demonstration, and deployment of these technologies. Advanced fossil technologies offer other benefits as well, in that they permit continued use of widely available fuels such as coal. An international perspective is critical for assessing the role of these fuels, since countries differ in terms of their ability to maximize these benefits. Often, new technologies are considered the domain of industrialized countries. Yet more efficient technologies may have their greatest potential - to concurrently permit the utilization of indigenous fuels and to lower global GHG emissions in developing countries, especially those in the Asia-Pacific region.

  14. Embedded Hyperchaotic Generators: A Comparative Analysis

    Sadoudi, Said; Tanougast, Camel; Azzaz, Mohamad Salah; Dandache, Abbas

    In this paper, we present a comparative analysis of FPGA implementation performances, in terms of throughput and resources cost, of five well known autonomous continuous hyperchaotic systems. The goal of this analysis is to identify the embedded hyperchaotic generator which leads to designs with small logic area cost, satisfactory throughput rates, low power consumption and low latency required for embedded applications such as secure digital communications between embedded systems. To implement the four-dimensional (4D) chaotic systems, we use a new structural hardware architecture based on direct VHDL description of the forth order Runge-Kutta method (RK-4). The comparative analysis shows that the hyperchaotic Lorenz generator provides attractive performances compared to that of others. In fact, its hardware implementation requires only 2067 CLB-slices, 36 multipliers and no block RAMs, and achieves a throughput rate of 101.6 Mbps, at the output of the FPGA circuit, at a clock frequency of 25.315 MHz with a low latency time of 316 ns. Consequently, these good implementation performances offer to the embedded hyperchaotic Lorenz generator the advantage of being the best candidate for embedded communications applications.

  15. Integrity Analysis of Damaged Steam Generator Tubes

    1998-01-01

    Variety of degradation mechanisms affecting steam generator tubes makes steam generators as one of the critical components in the nuclear power plants. Depending of their nature, degradation mechanisms cause different types of damages. It requires performance of extensive integrity analysis in order to access various conditions of crack behavior under operating and accidental conditions. Development and application of advanced eddy current techniques for steam generator examination provide good characterization of found damages. Damage characteristics (shape, orientation and dimensions) may be defined and used for further evaluation of damage influence on tube integrity. In comparison with experimental and analytical methods, numerical methods are also efficient tools for integrity assessment. Application of finite element methods provides relatively simple modeling of different type of damages and simulation of various operating conditions. The stress and strain analysis may be performed for elastic and elasto-plastic state with good ability for visual presentation of results. Furthermore, the fracture mechanics parameters may be calculated. Results obtained by numerical analysis supplemented with experimental results are the base for definition of alternative plugging criteria which may significantly reduce the number of plugged tubes.

    With utilities in the U.S. and around the world increasingly moving toward smart grid technology and other upgrades with inherent cyber vulnerabilities, correlative threats from malicious cyber attacks on the North American electric grid continue to grow in frequency and sophistication. The potential for malicious actors to access and adversely affect physical electricity assets of U.S. electricity generation, transmission, or distribution systems via cyber means is a primary concern for utilities contributing to the bulk electric system. This paper seeks to illustrate the current cyber-physical landscape of the U.S. electric sector in the context of its vulnerabilities to cyber attacks, the likelihood of cyber attacks, and the impacts cyber events and threat actors can achieve on the power grid. In addition, this paper highlights utility perspectives, perceived challenges, and requests for assistance in addressing cyber threats to the electric sector. There have been no reported targeted cyber attacks carried out against utilities in the U.S. that have resulted in permanent or long term damage to power system operations thus far, yet electric utilities throughout the U.S. have seen a steady rise in cyber and physical security related events that continue to raise concern. Asset owners and operators understand that the effects of a coordinated cyber and physical attack on a utility’s operations would threaten electric system reliability–and potentially result in large scale power outages. Utilities are routinely faced with new challenges for dealing with these cyber threats to the grid and consequently maintain a set of best practices to keep systems secure and up to date. Among the greatest challenges is a lack of knowledge or strategy to mitigate new risks that emerge as a result of an exponential rise in complexity of modern control systems. This paper compiles an open-source analysis of cyber threats and risks to the electric grid, utility best practices

  1. Export orientation and domestic electricity generation: Effects on energy efficiency innovation in select sectors

    International Nuclear Information System (INIS)

    Urpelainen, Johannes

    2011-01-01

    Why are some countries developing many energy efficiency innovations, while others are lagging behind? I argue that export orientation and electricity at low variable cost from nuclear and hydropower plants have an interactive effect on energy efficiency innovation. Export-oriented countries have strong incentives to invest in energy efficiency innovation, as they are in a position to export these technology innovations for global markets. But if inexpensive electricity is supplied in a country, the domestic demand for energy efficiency innovation is missing, and so the home market cannot serve as a springboard for international commercialization. I test this theory against international patent data on energy efficiency innovation in insulation, heating, and lighting for 22 OECD countries, 1991-2007. The statistical analysis indicates that export orientation has large positive effects on energy efficiency innovation in countries that do not rely on nuclear and hydroelectricity. - Highlights: → Export-oriented countries produce energy efficiency innovations. → Nuclear and hydropower reduce energy efficiency innovation. → Data on international patents from industrialized countries support the argument.

    Kenya's human resources for health shortage is well documented, yet in line with the new constitution, responsibility for health service delivery will be devolved to 47 new county administrations. This work describes the public sector nursing workforce likely to be inherited by the counties, and examines the relationships between nursing workforce density and key indicators. National nursing deployment data linked to nursing supply data were used and analyzed using statistical and geographical analysis software. Data on nurses deployed in national referral hospitals and on nurses deployed in non-public sector facilities were excluded from main analyses. The densities and characteristics of the public sector nurses across the counties were obtained and examined against an index of county remoteness, and the nursing densities were correlated with five key indicators. Of the 16,371 nurses in the public non-tertiary sector, 76% are women and 53% are registered nurses, with 35% of the nurses aged 40 to 49 years. The nursing densities across counties range from 1.2 to 0.08 per 1,000 population. There are statistically significant associations of the nursing densities with a measure of health spending per capita (P value = 0.0028) and immunization rates (P value = 0.0018). A higher county remoteness index is associated with explaining lower female to male ratio of public sector nurses across counties (P value public sector countrywide is complicated by mal-distribution and varying workforce characteristics (for example, age profile) across counties. All stakeholders should support improvements in human resources information systems and help address personnel shortages and mal-distribution if equitable, quality health-care delivery in the counties is to be achieved.

  8. Generalized cost-effectiveness analysis for national-level priority-setting in the health sector

    Directory of Open Access Journals (Sweden)

    2003-12-01

    Full Text Available Abstract Cost-effectiveness analysis (CEA is potentially an important aid to public health decision-making but, with some notable exceptions, its use and impact at the level of individual countries is limited. A number of potential reasons may account for this, among them technical shortcomings associated with the generation of current economic evidence, political expediency, social preferences and systemic barriers to implementation. As a form of sectoral CEA, Generalized CEA sets out to overcome a number of these barriers to the appropriate use of cost-effectiveness information at the regional and country level. Its application via WHO-CHOICE provides a new economic evidence base, as well as underlying methodological developments, concerning the cost-effectiveness of a range of health interventions for leading causes of, and risk factors for, disease. The estimated sub-regional costs and effects of different interventions provided by WHO-CHOICE can readily be tailored to the specific context of individual countries, for example by adjustment to the quantity and unit prices of intervention inputs (costs or the coverage, efficacy and adherence rates of interventions (effectiveness. The potential usefulness of this information for health policy and planning is in assessing if current intervention strategies represent an efficient use of scarce resources, and which of the potential additional interventions that are not yet implemented, or not implemented fully, should be given priority on the grounds of cost-effectiveness. Health policy-makers and programme managers can use results from WHO-CHOICE as a valuable input into the planning and prioritization of services at national level, as well as a starting point for additional analyses of the trade-off between the efficiency of interventions in producing health and their impact on other key outcomes such as reducing inequalities and improving the health of the poor.

    2012-01-01

    To-date, decomposition analysis has been widely used at the macro-economic level and for in-depth analyses of the industry and transport sectors; however, its application in the residential sector has been rare. This paper uses the Log-Mean Divisia Index I (LMDI-I) methodology to decompose gas consumption trends in the gas-connected residential sector in Ireland from 1990 to 2008, which despite an increasing number of energy efficiency policies, experienced total final consumption growth of 470%. The analysis decomposes this change in gas consumption into a number of effects, examining the impact over time of market factors such as a growing customer base, varying mix of dwelling types, changing share of vacant dwellings, changing size of new dwellings, the impact of building regulations policy and other factors such as the weather. The analysis finds the most significant effects are changing customer numbers and changing intensity; the analysis also quantifies the impact of building regulations and compares it with other effects such as changing size of new dwellings. By comparing the historical impact on gas consumption of policy factors and non-policy factors, this paper highlights the challenge for policy-makers in achieving overall energy consumption reduction. - Highlights: ► Contribution to a gap in the literature with a residential sector decomposition analysis of gas TFC. ► Activity effect had the largest impact and was cumulatively the best explainer of total TFC change. ► Intensity effect was the second biggest effect with a 19% share of total TFC change. ► In line with rising surface temperatures, the weather effect is declining over time. ► Building regulations are having a diminishing impact but are being negated by larger dwellings.

  10. Nuclear position in power generation sector - under the pressure of anti-global warming and power market reform

    2005-01-01

    The future structure surrounding fuel choice in power generation sector should be understood how to evaluate actual and potential merit and demerit both in economic and environmental aspects on nuclear power generation. That is i.e. nuclear can be understood as superior power source without GHGs and on the other hand, as unfavorable power source which might cause some critical dangers due to its hazardous radioactive nuclear waste. On this specific characteristic, this theme on fuel choice surrounding nuclear in power generation sector could be understood as a highly cultural problem as much as economic and political one. For instance, we can observe quite opposite direction with each other on nuclear power development in European countries like France and Finland on one hand and Germany and Sweden on the other hand. Looking at Asian countries, we also observe the very reality of high economic growth with rapid growth of electricity demand like China. What on earth, is it really possible without nuclear power source for such gigantic countries. I will develop my personal idea on nuclear power source based on Japanese experience towards successfully managing nuclear power technologies in the world, consisting of developing countries with growing economies and of advanced ones with rather matured nuclear technology under the pressure of environmentally restricted world order. My basic view point to discuss nuclear power problem has, conclusionally speaking, several aspects; The first one is in the relation with deregulation or liberalization of electricity market, which has been undergoing among such developed countries as OECD member countries i.e. USA, EU, Japan and other countries. Deregulation or liberalization of electricity market seems to be the inevitable process towards more matured market economy among developed countries group, and that process inevitably forces management of power companies towards more near sighted attitude if those companies are

    This study aims to search for economies of size and scope in the Portuguese water sector applying Bayesian and classical statistics to make inference in stochastic frontier analysis (SFA). This study proves the usefulness and advantages of the application of Bayesian statistics for making inference in SFA over traditional SFA which just uses classical statistics. The resulting Bayesian methods allow overcoming some problems that arise in the application of the traditional SFA, such as the bias in small samples and skewness of residuals. In the present case study of the water sector in Portugal, these Bayesian methods provide more plausible and acceptable results. Based on the results obtained we found that there are important economies of output density, economies of size, economies of vertical integration and economies of scope in the Portuguese water sector, pointing out to the huge advantages in undertaking mergers by joining the retail and wholesale components and by joining the drinking water and wastewater services. - Highlights: • This study aims to search for economies of size and scope in the water sector; • The usefulness of the application of Bayesian methods is highlighted; • Important economies of output density, economies of size, economies of vertical integration and economies of scope are found.

  13. Determinants of energy demand in the French service sector: A decomposition analysis

    2009-01-01

    This paper analyzes the changes in the energy consumption of the service sector in France over the period 1995-2006, using the logarithmic mean Divisia index I (LMDI I) decomposition method. The analysis is carried out at various disaggregation levels to highlight the specifics of each sub-sector and end-use according to their respective determinants. The results show that in this period the economic growth of the service sector was the main factor that led to the increase in total energy consumption. Structure, productivity, substitution and intensity effects restricted this growth, but with limited effect. By analyzing each end-use, this paper enables a more precise understanding of the impact of these factors. The activity effect was the main determinant of the increase in energy consumption for all end-uses except for air conditioning, for which the equipment rate effect was the main factor. Structural changes in the service sector primarily impacted energy consumption for space heating and cooking. Improvements in productivity limited the growth of energy consumption for all end-uses except for cooking. Finally, energy efficiency improvements mainly affected space-heating energy use.

    2014-12-01

    Full Text Available Hospitals are considered complex organizations mainly due to the high cost of the health care structure employed for care. Reducing operating costs is a challenge for hospital managers. Particularly in the clinical engineering sector, adequate hospital logistics can reduce costs. In this context, the aim of the research was to analyze the activities of hospital logistics of the Clinical Engineering department at a charity hospital, focusing on cost reduction. The paper presents a case study in a large charity hospital located in the metropolitan region of Belo Horizonte, MG. The analysis focuses on the activities of hospital logistics at this hospital clinical engineering sector. The work in this sector is concentrated in the realization and implementation of equipment maintenance, to the detriment of efforts to reduce costs and increase safety for all streams managed by the sector. It was also found that there are risks of increased costs with inadequate routines: (i acquisition of new and large equipment; (ii maintenance and release schedule for use; and (iii the theft of equipment.

    For this study, we constructed the following three case scenarios based on the Taiwanese government's energy policy: a normal scenario, the 2008 “Sustainable Energy Policy Convention” scenario, and the 2011 “New Energy Policy” scenario. We then employed a long-term Generation Expansion Planning (GEP) optimization model to compare the three case scenarios' energy mix for power generation for the next å15 years to further explore their possible impact on the electricity sector. The results provide a reference for forming future energy policies and developing strategic responses. - Highlights: • We constructed three case scenarios based on the Taiwan government's energy policy. • We employed a long-term Generation Expansion Planning optimization model. • A significant gap exists between the carbon reduction target and baseline. • The carbon reduction target requires a holistic resolution needed taking seriously

  17. Energy use efficiency in the Indian manufacturing sector: An interstate analysis

    Mukherjee, Kankana

    2008-01-01

    This paper approaches the measurement of energy efficiency from a production theoretic framework and uses Data Envelopment Analysis to measure energy efficiency in the Indian manufacturing sector. Using data from the Annual Survey of Industries for the years 1998-99 through 2003-04, the study compares the energy efficiency in manufacturing across states, based on several models. The results show considerable variation in energy efficiency across states. Comparing the results across our models, we find that the relative pricing of energy does not provide the appropriate incentives for energy conservation. A second-stage regression analysis reveals that states with a larger share of manufacturing output in energy-intensive industries have lower energy efficiency. Also, higher quality labor force associates with higher energy efficiency. Finally, the power sector reforms have not yet had any significant impact on achieving energy efficiency

    Diabetes mellitus contributes substantially to the non-communicable disease burden in South Africa. The proposed National Health Insurance system provides an opportunity to consider the development of a cost-effective capitation model of care for patients with type 2 diabetes. The objective of the study was to determine the potential cost-effectiveness of adapting a private sector diabetes management programme (DMP) to the South African public sector. Cost-effectiveness analysis was undertaken with a public sector model of the DMP as the intervention and a usual practice model as the comparator. Probabilistic modelling was utilized for incremental cost-effectiveness ratio analysis with life years gained selected as the outcome. Secondary data were used to design the model while cost information was obtained from various sources, taking into account public sector billing. Modelling found an incremental cost-effectiveness ratio (ICER) of ZAR 8 356 (USD 1018) per life year gained (LYG) for the DMP against the usual practice model. This fell substantially below the Willingness-to-Pay threshold with bootstrapping analysis. Furthermore, a national implementation of the intervention could potentially result in an estimated cumulative gain of 96 997 years of life (95% CI 71 073 years - 113 994 years). Probabilistic modelling found the capitation intervention to be cost-effective, with an ICER of ZAR 8 356 (USD 1018) per LYG. Piloting the service within the public sector is recommended as an initial step, as this would provide data for more accurate economic evaluation, and would also allow for qualitative analysis of the programme.

    2015-12-01

    Full Text Available The risk, as a concept found in the economic sphere of business represents an analysis area often approached by researchers from the finance and accounting field. Although it is often seen, along with cost-effectiveness and value, as a fundamental element of finance (Stancu, I., 2007, the risk has often facets that make it useful also in analyzing other sides of the economic sphere of business, such as financial position and economic performance of it. From these meanings, we believe that the most suitable for this purpose is the one through which it is analyzed the ability of an entity to avoid bankruptcy. The present study has as main objectives the presentation of bankruptcy risk of an entity from a theoretical point of view and the analysis (from an empirical and comparative point of view through the scoring method of the implementation of various models for analyzing the risk of bankruptcy (Altman, Conan-holder, Taffler, Robertson in Romania’s energy sector, in order to issue an opinion regarding the optimal method for analyzing the bankruptcy risk in the energy sector. The results show that there are significant differences regarding the analysis of the bankruptcy risk through the appliction of different models, proposing the Conan-Holder model as the most appropriate for this sector.

    The world-wide necessity of greenhouse gases mitigation and the intergovernmental mobilization to reach the objectives established by the United Nations Framework on Climate Change (UNFCCC) has opened space for the renewable energy increase in the world's energy matrix. In Brazil, the solid sugarcane industry currently develops business in the scope of the clean development mechanism (CDM) under the Kyoto's Protocol, by means of 18 biomass-based projects, with renewable energy generation through bagasse cogeneration at 20 Sao Paulo State's sugarcane production units. The projects activity's consists of increasing the efficiency in the bagasse cogeneration facilities, qualifying the units to sell surplus electricity to the national grid, avoiding the dispatch of the same amount of energy produced by fossil-fuelled thermal plants to that grid. The reduced emissions are measured in carbon equivalent and can be converted into negotiable credits. The objective of this study was to build a 'state of art' scenario, calculating the potential emissions reduction through CDM projects for the sugarcane sector of Sao Paulo State, in which we consider the adherence of all the production units of the State to the CDM projects. The technological parameters used to elaborate the scenario were provided by the Sao Paulo State Government Bioenergy Special Commission and the baseline factor used of 0,268 tCO{sub 2}e/MWh was the adopted by the CDM projects in operation in the State. The sugarcane database for the calculations was the production ranking provided by UNICA for the 2006/2007 season. In the most conservative scenario (40 bar bagasse) 131 units could generate 607 MWm of surplus power avoiding the emission of 1.404.593 tCO{sub 2}e/year. For the 92 bar (bagasse and straw) scenario, the units could generate 3.055 MWm of surplus power avoiding 12.199.443 tCO{sub 2}e/year. (author)

    2012-04-01

    The analysis of drought impacts is essential to define efficient and sustainable management and mitigation. In this paper we present a detailed analysis of the impacts of the 2004-2008 drought in the agricultural sector in the Ebro river basin (Spain). An econometric model is applied in order to determine the magnitude of the economic loss attributable to water scarcity. Both the direct impacts of drought on agricultural productivity and the indirect impacts of drought on agricultural employment and agroindustry in the Ebro basin are evaluated. The econometric model measures losses in the economic value of irrigated and rainfed agricultural production, of agricultural employment and of Gross Value Added both from the agricultural sector and the agro-industrial sector. The explanatory variables include an index of water availability (reservoir storage levels for irrigated agriculture and accumulated rainfall for rainfed agriculture), a price index representative of the mix of crops grown in each region, and a time variable. The model allows for differentiating the impacts due to water scarcity from other sources of economic losses. Results show how the impacts diminish as we approach the macro-economic indicators from those directly dependent on water abstractions and precipitation. Sectors directly dependent on water are the most affected with identifiable economic losses resulting from the lack of water. From the management perspective implications of these findings are key to develop mitigation measures to reduce drought risk exposure. These results suggest that more open agricultural markets, and wider and more flexible procurement strategies of the agro-industry reduces the socio-economic exposure to drought cycles. This paper presents the results of research conducted under PREEMPT project (Policy relevant assessment of the socioeconomic effects of droughts and floods, ECHO - grant agreement # 070401/2010/579119/SUB/C4), which constitutes an effort to provide

  16. Analysis of the market penetration of clean coal technologies and its impacts in China's electricity sector

    International Nuclear Information System (INIS)

    Wang, Hao; Nakata, Toshihiko

    2009-01-01

    This paper discusses policy instruments for promoting the market penetration of clean coal technologies (CCTs) into China's electricity sector and the evaluation of corresponding effects. Based on the reality that coal will remain the predominant fuel to generate electricity and conventional pulverized coal boiler power plants have serious impacts on environment degradation, development of clean coal technologies could be one alternative to meet China's fast growing demand of electricity as well as protect the already fragile environment. A multi-period market equilibrium model is applied and an electricity model of China is established to forecast changes in the electricity system up to 2030s. Three policy instruments: SO 2 emission charge, CO 2 emission charge and implementing subsidies are considered in this research. The results show that all instruments cause a significant shift in China's electricity structure, promote CCTs' competitiveness and lead China to gain great benefit in both resource saving and environment improvement. Since resource security and environment degradation are becoming primary concerns in China, policies that could help to gain generations' market share of advanced coal-based technologies such as CCTs' is suitable for the current situation of China's electricity sector.

  19. Power sector scenarios for Thailand: An exploratory analysis 2002-2022

    International Nuclear Information System (INIS)

    Mulugetta, Yacob; Mantajit, Nathinee; Jackson, Tim

    2007-01-01

    Power sector scenarios for Thailand are constructed in this paper to represent the range of opportunities and constraints associated with divergent set of technical and policy options. They include Business-As-Usual (BAU), No-New-Coal (NNC), and Green Futures (GF) scenarios over a 20-year period (2002-2022). The results from the BAU scenario show that fossil fuels will continue to dominate electricity generation in Thailand during the study period. Similar results are obtained for the NNC option, although the dependence shifts from coal and oil towards natural gas-based power generation. This may represent a better environmental pathway but an all out shift from coal to natural gas is likely to increase Thailand's dependence on imported fuel, making it more vulnerable to unstable global oil and gas prices. The GF scenario offers a more optimistic route that allows the country to confront its energy security dilemma whilst fulfilling its environmental commitments by giving renewable energy technologies a prominent place in the country's power generation mix. Over the study period, our result showed little difference between the three scenarios in terms of financing new generation plants despite an early misgiving about the viability of an ambitious renewable energy programme. This paper also goes beyond the financial evaluation of each scenario to provide a comparison of the scenarios in terms of their greenhouse gas emissions together with the comparative costs of emissions reductions. Indeed, if such externalities are taken into account to determine 'viability', the GF scenario represents an attractive way forward for the Thai power sector

In the analysis of basic production funds, the factors that impede the efficiency of production funds were established as follows: the greatest negative impact on basic production funds efficiency of businesses was in small tower crane fleet; a small range of tower cranes in the park is reducing the technical possibilities of the lease. Basing on the analysis and observation of tower cranes installation and dismantling, the poor supply of the parts for the work place, lack of competence and motivation of the support staff have been ascertained. After elimination of these factors it is possible to raise the efficiency of the main production funds.Article in Lithuanian

  1. Analysis of multi-pollutant policies for the U.S. power sector under technology and policy uncertainty using MARKAL

    2010-01-01

    Investments in power generation, pollution controls, and electricity end use equipment are made in the face of uncertainty. Unanticipated events can cause regret-commitments that in retrospect were the wrong choices. We analyze how three uncertainties-electricity demand growth, natural gas prices, and power sector greenhouse gas regulations-could affect electric power sector investment decisions and costs in the U.S. over the next four decades. The effect of multi-pollutant regulations such as the Clean Air Interstate Rule (CAIR) upon these decisions and costs is also considered. We use decision trees to structure the problem, defining multiple futures for each uncertainty and then simulating how the U.S. energy market responds to them. A two-stage stochastic version of the energy-economy model MARKAL simulates the market. Relative importance of the uncertainties is assessed using two indices: expected cost of ignoring uncertainty (ECIU) and expected value of perfect information (EVPI). We also calculate the value of policy coordination (VPC), the cost saved by avoiding surprise changes in policy. An example shows how a stochastic program can be used to compute these indices. The analysis shows that the possibility of greenhouse gas regulation is the most important uncertainty by these measures.

  2. Decarbonizing the European electricity sector. Modeling and policy analysis for electricity and CO_2 infrastructure networks

    2016-01-01

    This dissertation uses three models to analyze different decarbonization strategies for combating global climate change: The cost minimizing mixed-integer model CCTS-Mod examines the economics of Carbon Capture, Transport, and Storage (CCTS) for the electricity and industry sector; the welfare maximizing quadratically constrained model ELMOD focuses on different trajectories for renewable energy sources (RES) and transmission grid expansions; and the equilibrium model ELCO combines the insights of the individual sectors to a combined CCTS and electricity investment and dispatch model. Modeling results show that an investment in CCTS is beneficial for the iron and steel sector once the CO_2 certificate price exceeds 50 Euros/t CO_2. The threshold is 75 Euros/t CO_2 for the cement industry and 100 Euros/t CO_2 for the electricity sector. Additional revenues from using CO_2 for enhanced oil recovery (CO_2-EOR) lead to an earlier adoption of CCTS in the North Sea region. The lack of economies of scale results in increasing CO_2 storage costs of more than 30%, while transport costs even double. Research from the last years, however, indicates that CCTS is unlikely to play an important role in decarbonizing the electricity sector. The identified reasons for this are incumbents' resistance to structural change, wrong technology choices, over-optimistic cost estimates, a premature focus on energy projects instead of industry, and the underestimation of transport and storage issues. Keeping global temperature rise below 2 C therefore implies the phase-out of fossilfueled power plants and, in particular, of CO_2-intensive coal power plants. The low CO_2 price established by the European Emissions Trading Scheme is insufficient to induce a fuel switch in the medium term. Therefore, supplementary national measures are necessary to reduce coal-based power generation; i.a. feed-in tariffs for RES, minimum CO_2 prices, or emissions performance standards.

    Ceran, Nisangul

    The objective of this dissertation is to assess whether the private participation in energy sector through long term contracting, such as Build-Operate-Transfer (BOT) type investments, is an efficient way of promoting efficiency in the economy. To this end; the theoretical literature on the issue is discussed, the experience of several developing countries are examined, and a BOT project, which is undertaken by the Enron company in Turkey, has been studied in depth as a case study. Different risk analysis techniques, including sensitivity and probabilistic risk analysis with the Monte Carlo Simulation (MCS) method have been applied to assess the financial feasibility and risks of the case study project, and to shed light on the level of rent-seeking in the BOT agreements. Although data on rent seeking and corruption is difficult to obtain, the analysis of case study investment using the sensitivity and MCS method provided some information that can be used in assessing the level of rent-seeking in BOT projects. The risk analysis enabled to test the sustainability of the long-term BOT contracts through the analysis of projects financial feasibility with and without the government guarantees in the project. The approach of testing the sustainability of the project under different scenarios is helpful to understand the potential costs and contingent liabilities for the government and project's impact on a country's overall economy. The results of the risk analysis made by the MCS method for the BOT project used as the case study strongly suggest that, the BOT projects does not serve to the interest of the society and transfers substantial amount of public money to the private companies, implying severe governance problems. It is found that not only government but also private sector may be reluctant about full privatization of infrastructure due to several factors such as involvement of large sunk costs, very long time period for returns to be received, political and

    Full Text Available With the governmental sectors imitating the reformation of enterprises stressing on Knowledge, Contracting Out and Deregulation have become the core policies. Contracting Out is not based on the arbitrariness of an administrator, but the selective efficiency and competition. Connecting the resources between Public and Private Sectors is a concern of Contracting Out, while Knowledge Outsourcing is an innovation to enhance organizational knowledge and the reduction of organizational ignorance. Based on a Knowledge Outsourcing Investigation by the Kaohsiung City Government (Taiwan in the past few years, Data Envelopment Analysis (DEA and Sensitivity Analysis are integrated for measuring the total efficiency (TE, pure technical efficiency (PTE, and scale efficiency (SE of Knowledge Outsourcing of the sectors in the Kaohsiung City Government for the improvement reference of other counties and cities. From the message acquired from the efficiency and variables with the DEA, one DMU (Data Management Unit, or about 5% of all DMUs, appears to have strong Knowledge Outsourcing efficiency 1, showing favorable Knowledge Outsourcing efficiency. Two DMUs, comprising about 10% of all DMUs, reveal the marginal Knowledge Outsourcing inefficiency between 0.9 and 1. This implies that such sectors could better enhance the Knowledge Outsourcing efficiency. 17 DMUs, representing about 85% of all DMUs, exhibit an obvious Knowledge Outsourcing inefficiency of less than 0.9, so that the Finance and Transportation Bureaus present the lowest Knowledge Outsourcing efficiency.En la medida en que el sector público imita la reforma de aquellas empresas que ponen el acento en el conocimiento, la subcontratación y la desregulación se han convertido en las principales políticas. La subcontratación no se basa en la arbitrariedad de un gestor público, sino en la eficacia selectiva y la competencia. El interés de la subcontratación consiste en poner en contacto los recursos

    2016-02-15

    This study aims to search for economies of size and scope in the Portuguese water sector applying Bayesian and classical statistics to make inference in stochastic frontier analysis (SFA). This study proves the usefulness and advantages of the application of Bayesian statistics for making inference in SFA over traditional SFA which just uses classical statistics. The resulting Bayesian methods allow overcoming some problems that arise in the application of the traditional SFA, such as the bias in small samples and skewness of residuals. In the present case study of the water sector in Portugal, these Bayesian methods provide more plausible and acceptable results. Based on the results obtained we found that there are important economies of output density, economies of size, economies of vertical integration and economies of scope in the Portuguese water sector, pointing out to the huge advantages in undertaking mergers by joining the retail and wholesale components and by joining the drinking water and wastewater services.

    Full Text Available The energy consumption of Korea’s manufacturing sector has sharply increased over the past 20 years. This paper decomposes the factors influencing energy consumption in this sector using the logarithmic mean Divisia index (LMDI method and analyzes the specific characteristics of energy consumption from 1991 to 2011. The analysis reveals that the activity effect played a major role in increasing energy consumption. While the structure and intensity effects contributed to the reduction in energy consumption, the structure effect was greater than the intensity effect. Over the periods, the effects moved in opposite directions; that is, the structure effect decreased when the intensity effect increased and vice versa. The energy consumption by each industry is decomposed into two factors, activity and intensity effects. The increase of energy consumption due to the activity effect is largest in the petroleum and chemical industry, followed by the primary metal and non-ferrous industry, and the fabricated metal industry. The decrease of energy consumption due to the intensity effect is largest in the fabricated metal industry, followed by the primary metal and non-ferrous industry, and the non-metallic industry. The energy consumption due to intensity effect in the petroleum and chemical industry has risen. To save energy consumption more efficiently for addressing climate change in this sector, industrial restructuring and industry-specific energy saving policies should be introduced.

    2015-05-01

    In 2009, a reregulation of the Swedish pharmacy sector took place, and a fundamental change in ownership and structure followed. The reregulation provides an opportunity to reveal the politicians' views on pharmacies. The aim of this study was to explore and analyze the political arguments for the reregulation of the Swedish pharmacy sector in 2009. The method used was a qualitative content analysis of written political documents regarding the reregulation. The primary rationales for the reregulation were better availability, efficiency, price pressure, and safe usage of medicines. During the preparatory work, the rationales of diversity on the market and entrepreneurship were added, while the original rationales of efficiency, price pressure, and better usage of medicines were abandoned. The reform can be seen as a typical New Public Management reform influenced by the notion that private actors are better equipped to perform public activities. The results point to that the reform was done almost solely in order to introduce private ownership in the pharmacy sector, and was not initiated in order to solve any general problems, or to enhance patient outcomes of medicine use.

  10. A decomposition analysis of the driving factors of CO_2 (Carbon dioxide) emissions from the power sector in the European Union countries

    International Nuclear Information System (INIS)

    2016-01-01

    The scope of this paper is to investigate the driving factors of CO_2 emissions from electricity generation in all European Union countries (EU-28) during the period 2000–2012. Particular emphasis is placed on the assessment of any potential association between the examined driving factors and major climate and energy policies implemented during the examined period. In addition, the analysis distinguishes two subperiods, namely 2000–2007 and 2007–2012 in order to detect the impact of the economic crisis on each distinct driving factor and, consequently, on the total level of CO_2 emissions from the power sector. The model developed to analyse the changes in CO_2 emissions from the power sector across EU-28, is based on LMDI-I method and takes into account five driving factors: level of activity, electricity intensity, electricity trade, efficiency of electricity generation and fuel mix. The obtained results show that in times of economic growth the main factor counterbalancing the activity effect was in most countries the decreasing electricity intensity, while the contribution of all other factors becomes apparent later, despite the economic crisis and in view of the Kyoto targets. - Highlights: • LMDI is used to identify driving forces of CO_2 emissions from EU's power sector. • Declining electricity intensity was the main restrictive factor before 2007. • Fuel shifts contributed to emissions fall mostly after 2007, despite the crisis. • Trade effect is notable and indicates growing carbon leakage in the power sector.

Other environmental impacts are described. Recommendations for supply and environment policy are presented

  12. Analysis of hydrocarbons generated in coalbeds

    Science.gov (United States)

    Butala, Steven John M.

    This dissertation describes kinetic calculations using literature data to predict formation rates and product yields of oil and gas at typical low-temperature conditions in coalbeds. These data indicate that gas formation rates from hydrocarbon thermolysis are too low to have generated commercial quantities of natural gas, assuming bulk first-order kinetics. Acid-mineral-catalyzed cracking, transition-metal-catalyzed hydrogenolysis of liquid hydrocarbons, and catalyzed CO2 hydrogenation form gas at high rates. The gaseous product compositions for these reactions are nearly the same as those for typical natural coalbed gases, while those from thermal and catalytic cracking are more representative of atypical coalbed gases. Three Argonne Premium Coals (Upper-Freeport, Pittsburgh #8 and Lewiston-Stockton) were extracted with benzene in both Soxhlet and elevated pressure extraction (EPE) systems. The extracts were compared on the basis of dry mass yield and hydrocarbon profiles obtained by gas chromatography/mass spectrometry. The dry mass yields for the Upper-Freeport coal gave consistent results by both methods, while the yields from the Pittsburgh #8 and Lewiston-Stockton coals were greater by the EPE method. EPE required ˜90 vol. % less solvent compared to Soxhlet extraction. Single-ion-chromatograms of the Soxhlet extracts all exhibited bimodal distributions, while those of the EPE extracts did not. Hydrocarbons analyzed from Greater Green River Basin samples indicate that the natural oils in the basin originated from the coal seams. Analysis of artificially produced oil indicates that hydrous pyrolysis mimics generation of C15+ n-alkanes, but significant variations were found in the branched alkane, low-molecular-weight n-alkanes, and high-molecular-weight aromatic hydrocarbon distributions.

    Full Text Available El cooperativismo agrario ha estado ligado desde sus orígenes al sector de las frutas y hortalizas, sector que arrastra desde hace años una problemática de carácter estructural, incrementada, sobretodo en el caso de la fruta, por las graves crisis de precios, la saturación de los mercados y una competencia creciente de las importaciones de terceros países. En este difícil marco, los productores deben seguir invirtiendo para mantener la competitividad y la rentabilidad de sus explotaciones, y las cooperativas, por su importancia económica, deben acometer políticas que permitan garantizar la viabilidad de dicho sector. En el presente trabajo realizamos un análisis del sector cooperativo frutícola catalán, con el fin de detectar sus puntos fuertes y débiles, así como posibles carencias y demandas. Las conclusiones muestran que las cooperativas son importantes en el sector de la fruticultura, debido sobretodo a su contribución activa a la conservación del territorio y su papel generador de empleo en numerosas zonas rurales. Pero se hace necesario la adopción de firmes decisiones y la implantación de medidas de apoyo que permitan garantizar los intereses de los socios y las necesidades de los consumidores./ The agricultural cooperatives have been linked from the origins to fruit and vegetable sector. This sector dragged on for years a structural problem, increased, especially in the case of fruit, for serious price crisis, the market saturation and increasing competition.

    2012-01-01

    This study addressed the controversial issue of disaster waste treatment in the reconstruction efforts following the Great East Japan Earthquake. Using the Sector Model (Matsumoto 2009), we categorized a range of actions taken in relation to the cross-jurisdictional treatment into the four sectors, government, industry, academia, and private. The analysis through this Sector Model made it possible to map the entire layout of waste treatment, inclusive of less-visible industry and academia sectors. Accordingly, we have argued that differences of risk awareness are not necessarily due to sector differences but rather depend on two aspects of the disaster waste treatment; the safety levels and the nationwide treatment of waste in Japan. We further suggest that the discrepancy in the arguments on safety levels emerged as a result of scientific under-determination and cross-jurisdictional treatment from social and/or political under-determination.

    Balkan countries in the process of joining the European Union shall adopt greenhouse gas emissions reduction targets and implement appropriate mitigation policies and measures. This paper presents a simplified methodological framework based on marginal abatement cost curves for estimating the technical and economic mitigation potential at sectoral level (buildings and road transport) in selected Balkan countries. The results of the analysis provide to decision makers useful information regarding the availability of background data, the potential for setting ambitious mitigation targets, and detailed tools for assisting the selection of policies and measures to meet these targets. The analysis performed shows that a significant part of the greenhouse gas emissions abatement potential can be achieved through win–win measures. The incorporation of environmental externalities associated with these interventions, estimated through benefits transfer, further improves the economic performance of these measures, especially in the buildings sector. Moreover, the implementation of these measures is shown to result in positive macroeconomic effects through increases in GDP (gross domestic product) and creation of new jobs. Finally, the rebound effect may restrict the estimated greenhouse gas emission reductions in the buildings of the countries examined due to the low energy performance of the existing building stock. - Highlights: • Analysis of the technical and economic GHG mitigation potential in western Balkans. • Marginal abatement cost curves highlight several win–win interventions. • Incorporation of environmental benefits improves the performance of measures. • Mitigation measures result in significant positive macroeconomic effects. • The investment costs and the rebound effect may influence measures' effectiveness.

    Restructuring has changed the traditional mission and mandates of power utilities in complex ways, and had large impacts on environmental, social, and political conditions for any particular country. At the same time, new regulatory approaches are being found for reducing environmental impacts in restructured power sectors. India has a vast supply of renewable energy resources, and it has one of the largest programs in the world for deploying renewable energy based products and systems. So this paper attempts to review the various policies and measures undertaken by Indian government for promotion of renewable energy. The aim of this paper is also to review the current policy mechanisms, especially investment- or generation-based price-driven and capacity-driven mechanisms, ranging from investment incentives for the development of renewable energy projects, feed-in tariffs, production tax incentives, tradable green certificates, and their effects upon the prospects of encouraging as well as expanding the development of renewable energy in Indian restructured power sector. This will make renewable more attractive in the Indian future electricity market. (author)

    There are substantial challenges facing humanity in the water and related sectors and purposeful integration of the disciplines, connected sectors and interest groups is now perceived as essential to address them. This article describes and uses bibliometric analysis techniques to provide quantitative insights into the general landscape of Integrated Water Resource Assessment and Modelling (IWAM) research over the last 45 years. Keywords, terms in titles, abstracts and the full texts are used to distinguish the 13,239 IWAM articles in journals and other non-grey literature. We identify the major journals publishing IWAM research, influential authors through citation counts, as well as the distribution and strength of source countries. Fruitfully, we find that the growth in numbers of such publications has continued to accelerate, and attention to both the biophysical and socioeconomic aspects has also been growing. On the other hand, our analysis strongly indicates that the former continue to dominate, partly by embracing integration with other biophysical sectors related to water - environment, groundwater, ecology, climate change and agriculture. In the social sciences the integration is occurring predominantly through economics, with the others, including law, policy and stakeholder participation, much diminished in comparison. We find there has been increasing attention to management and decision support systems, but a much weaker focus on uncertainty, a pervasive concern whose criticalities must be identified and managed for improving decision making. It would seem that interdisciplinary science still has a long way to go before crucial integration with the non-economic social sciences and uncertainty considerations are achieved more routinely.

    Full Text Available The research urgency is caused by the implementation of the Federal strategy of development of small and medium business for the period up to 2030.The purpose of the study: determination of the regularities characteristic of the sectoral structure of small and medium business. Objectives of the study: to establish the patterns and trends, characterizing the current structure of small and medium business by types of economic activity and the number of their employees, the definition of specific indicators of the number of employees per enterprise, as well as estimation of the distribution of these parameters on the aggregates of entrepreneurial structures in the regions. The results of continuous monitoring activities of small and medium business in 2015 were used as input data. The study was based on the comparison of indicators for the business sector and the full circle of legal entities and individual entrepreneurs.Research methodology is based on the consideration of sets of entities generated by the sectoral and territorial characteristics. Modeling of the values’ differentiation of the number of workers per enterprise based on the development of the density function of the normal distribution.

    2003-05-01

    This report contains a description of a dynamic model for a doubly-fed induction generator implemented in the aeroelastic code HAWC. The model has physical input parameters (resistance, reactance etc.) and input variables (stator and rotor voltage and rotor speed). The model can be used to simulate the generator torque as well as the rotor and stator currents, active and reactive power. A perturbation method has been used to reduce the original generator model equations to a set of equations which can be solved with the same time steps as a typical aeroelastic code. The method is used to separate the fast transients of the model from the slow variations and deduce a reduced order expression for the slow part. Dynamic effects of the first order terms in the model as well as the influence on drive train eigenfrequencies and damping has been investigated. Load response during time simulation of wind turbine response have been compared to simulations with a linear static generator model originally implemented i HAWC. A 2 MW turbine has been modelled in the aeroelastic code HAWC. When using the new dynamic generator model there is an interesting coupling between the generator dynamics and a global turbine vibration mode at 4.5 Hz, which only occurs when a dynamic formulation of the generator equations is applied. This frequency can especially be seen in the electrical power of the generator and the rotational speed of the generator, but also as torque variations in the drive train. (au)

The suggestion that policies aimed at increasing productivity and raising skills while encouraging individual participation in the formal labour market are essential.

  7. Local and regional interactions between air quality and climate in New Delhi- A sector based analysis

    Science.gov (United States)

    Marrapu, Pallavi

    control efforts should take a regional perspective. Air quality projections in Delhi for 2030 are investigated. The Greenhouse Gas and Air Pollution I nteractions and Synergies (GAINS) model is used to generate a 2030 future emission scenario for Delhi using projections of air quality control measures and energy demands. Net reductions in CO concentrations by 50%, and increases of 140% and 40% in BC and NOx concentrations, respectively, are predicted. The net changes in concentration are associated with increases in transport and industry sectors. The domestic sector still has a significant contribution to air pollutant levels. The air quality levels show a profound effect under this scenario on the environment and human health. The increase in pollution from 2010 to 2030 is predicted to cause an increase in surface temperature by ˜0.65K. These increasing pollution levels also show effects on the radiative forcing. The high aerosols loading i.e. BC, PM2.5 and PM10 levels show strong influence on the short and longwave fluxes causing strong surface dimming and strong atmosphere heating due to BC. These results indicate transport and domestic sectors should be targeted for air quality and climate mitigations.

    What are the dominant stocks which drive the correlations present among stocks traded in a stock market? Can a correlation analysis provide an answer to this question? In the past, correlation based networks have been proposed as a tool to uncover the underlying backbone of the market. Correlation based networks represent the stocks and their relationships, which are then investigated using different network theory methodologies. Here we introduce a new concept to tackle the above question--the partial correlation network. Partial correlation is a measure of how the correlation between two variables, e.g., stock returns, is affected by a third variable. By using it we define a proxy of stock influence, which is then used to construct partial correlation networks. The empirical part of this study is performed on a specific financial system, namely the set of 300 highly capitalized stocks traded at the New York Stock Exchange, in the time period 2001-2003. By constructing the partial correlation network, unlike the case of standard correlation based networks, we find that stocks belonging to the financial sector and, in particular, to the investment services sub-sector, are the most influential stocks affecting the correlation profile of the system. Using a moving window analysis, we find that the strong influence of the financial stocks is conserved across time for the investigated trading period. Our findings shed a new light on the underlying mechanisms and driving forces controlling the correlation profile observed in a financial market.

    Full Text Available The objective of this research was to analyze the quality of work life in the sewing sector of a clothing industry located in the Northwest of the Paraná. The research is characterized as an exploratory and descriptive case study. The instrument of data collection was an adaptation of the model considered for Walton. For data analysis descriptive statistics and the diagram of boxes were used (boxplot. The results had disclosed that the eight criterions of the quality of work life investigated had presented levels of satisfaction greater than 50%. A satisfactory general average can be evidenced (66.85% among the employees of the sewing sector in relation to the quality of work life. Although the presented levels of satisfaction, it would be interesting to take some measures aiming to improve them even more. These measures should be directed to the analysis of the criterion “proper and fair compensation”, which presented the worst average and greater dispersion among investigated criteria.

    Full Text Available Purpose: To facilitate futures business research by proposing a novel way to combine business models as a conceptual tool with futures research techniques. Design: A futures perspective is adopted to foresight business models of the Internet of Things (IoT enabled healthcare sector by using business models as a futures business research tool. In doing so, business models is coupled with one of the most prominent foresight methodologies, Causal Layered Analysis (CLA. Qualitative analysis provides deeper understanding of the phenomenon through the layers of CLA; litany, social causes, worldview and myth. Findings: It is di cult to predict the far future for a technology oriented sector like healthcare. This paper presents three scenarios for short-, medium- and long-term future. Based on these scenarios we also present a set of business model elements for different future time frames. This paper shows a way to combine business models with CLA, a foresight methodology; in order to apply business models in futures business research. Besides offering early results for futures business research, this study proposes a conceptual space to work with individual business models for managerial stakeholders. Originality / Value: Much research on business models has offered conceptualization of the phenomenon, innovation through business model and transformation of business models. However, existing literature does not o er much on using business model as a futures research tool. Enabled by futures thinking, we collected key business model elements and building blocks for the futures market and ana- lyzed them through the CLA framework.

    1982-01-01

    Computer programs were developed which calculate the in-duct acoustic modes excited by a fan/stator stae operating at subsonic tip speed. Three noise source mechanisms are included: (1) sound generated by the rotor blades interacting with turbulence ingested into, or generated within, the inlet duct; (2) sound generated by the stator vanes interacting with the turbulent wakes of the rotors blades; and (3) sound generated by the stator vanes interacting with the mean velocity deficit wakes of the rotor blades. The fan/stator stage is modeled as an ensemble of blades and vanes of zero camber and thickness enclosed within an infinite hard-walled annular duct. Turbulence drawn into or generated within the inlet duct is modeled as nonhomogeneous and anisotropic random fluid motion, superimposed upon a uniform axial mean flow, and convected with that flow. Equations for the duct mode amplitudes, or expected values of the amplitudes, are derived.

    2010-01-01

    This article extends the understanding of oil-stock market relationships over the last turbulent decade. Unlike previous empirical investigations, which have largely focused on broad-based market indices (national and/or regional indices), we examine short-term linkages in the aggregate as well as sector by sector levels in Europe using different econometric techniques. Our main findings suggest that the reactions of stock returns to oil price changes differ greatly depending on the activity sector. In the out-of-sample analysis we show that introducing oil asset into a diversified portfolio of stocks allows to significantly improve its risk-return characteristics. (author)

    2005-04-15

    Degradation of steam generator leads to forced outage and extension of outage, which causes increase in repair cost, cost of purchasing replacement power and radiation exposure of workers. Steam generator tube rupture incident occurred in Uljin 4 in 2002, which made public sensitive to nuclear power plant. To keep nuclear energy as a main energy source, integrity of steam generator should be demonstrated. Quantitative relationship between ECT(eddy current test) signal and crack size is needed in assesment of integrity of steam generator in pressurized water reactor. However, it is not fully established for application in industry. Retired steam generator of Kori 1 has many kinds of crack such as circumferential and axial primary water stress corrosion crack and outer diameter stress corrosion crack(ODSCC). So, it can be used in qualifying and improving ECT technology and in condition monitoring assesment for crack detected in ISI(in service inspection). In addition, examination of pulled tube of Kori 1 retired steam generator will give information about effectiveness of non welded sleeving technology which was employed to repair defect tubes and remedial action which was applied to mitigate ODSCC. In this project, hardware such as semi hot lab. for pulled tube examination and modification transportation cask for pulled tube and software such as procedure of transportation of radioactive steam generator tube and non-destructive and destructive examination of pulled tube were established. Non-destructive and destructive examination of pulled tubes from Kori 1 retired steam generator were performed in semi hot lab. Remedial actions applied to Kori 1 retired steam generator, PWSCC trend and bulk water chemistry and crevice chemistry in Kori 1 were evaluated. Electrochemical decontamination technology for pulled tube was developed to reduce radiation exposure and enhance effectiveness of pulled tube examination.

    Full Text Available In this article, the causes and consequences of IT projects’ budgets reformatting in banking organizations are investigated. Analysis and parallels in approaches of choosing IT projects to be implemented in foreign and Ukrainian financial institutions are being conducted. This significantly affects not only the results of investigation and selection of IT projects but also on the development of such organizations in general. The analysis shows that on the background of global GDP decrease, banks around the world are increasing their IT investments, but investments in IT projects are heavily redistributed towards digital transformation. Nevertheless, IT projects are a major driver of banking business development, so their number is rapidly growing every day in the fields of big data analytics, virtualization and cloud computing, mobility, scoring, target marketing, IT infrastructure etc. The authors draw conclusions about trends in implementation of IT projects and their impact on the development of the banking business sector.

    2018-02-01

    Poverty is a multidimensional problem. Therefore, poverty reduction policy is not only related to the increase of income, but also various other dimensions such as improvement of education, health, quality of life, access to electricity, access to sanitation and water supply. Semarang City Government in 2012 initiated a policy of poverty reduction synergy program called “Gerdu Kempling”. Gerdu Kempling is an integrated policy which gives priority to addressing poverty in each village and sub-district in Semarang based on aspects of health, economy, education, infrastructure, and environment. Based on the results of Budget Allocation Analysis and Analysis of Geographic Information Systems (Poverty Mapping), it can be concluded that the program and budget allocation for poverty alleviation in Semarang City are not synchronized either spatially or sectorally.

    Tang, Chor Foon; Shahbaz, Muhammad

    2013-01-01

    This study uses the annual data from 1972 to 2010 to assess the causal relationship between electricity consumption and real output at the aggregate and sectoral levels in Pakistan. This study covers three main economic sectors in Pakistan namely agricultural, manufacturing and services sectors. Our cointegration results reveal that the variables are cointegrated at the aggregate and sectoral levels. At the aggregate level, we find that there is uni-directional Granger causality running from electricity consumption to real output in Pakistan. At the sectoral level, we find that electricity consumption Granger-causes real output in the manufacturing and services sectors. However, there is no causal relationship between electricity consumption and real output in the agricultural sector. The policy implication of these results is that electricity conservation policies in general would deteriorate the process of economic growth as well as the real output in the manufacturing and services sectors in Pakistan. Nevertheless, we suggest the Pakistani government to implement the electricity conservation policies merely to the agricultural sector because such policies may have less or no adverse impact on its real output. - Highlights: • We assess the electricity-growth nexus in Pakistan at the aggregate and sectoral levels. • The variables are cointegrated at both levels. • We find causality from electricity to output at the aggregate level and services. • We find neutral causality in the agricultural sector. • We find bi-directional causality in the manufacturing sector

    Group of Eight developed countries (D8 plus China. Technology spillover indexes are thus decomposed into two components: Imports of capital goods and foreign direct investment (FDI. Index of capital goods imports measures imports of capital goods from major commercial partners of Iran (D8 countries and china. Foreign direct investment (FDI represents the share of foreign capital in agricultural sectors. Therefore, the empirical analysis of the technology spillover on the productivity of agricultural sectors is based on theatrical framework and ARDL model. Results and Discussion: According to the results of the ARDL model, technological spillover effect on the TFP of agricultural sector, in long-term shows that technology spillover has a positive and significant effect on agricultural productivity from both channels of capital goods import and foreign direct investment (FDI. But in short-term spillover variable from a capital goods import channel is not significant. This indicates that absorption of the technology from imports of capital goods channel do not perform very well and probably low-tech and without affecting on TFP of agriculture sector is imported. But in long-term technology spillover from imports channels also had a positive impact on total factor productivity of the agricultural sector. In fact, high technologies in long-term can be absorbed through the imports and influenced on TFP. According to thesis study results, the estimated coefficient of error correction term is equal to 0.53.This means that in each period, 53 percent of imbalances of agricultural TFP will be resolved. The average speed of upward of adjustment reflects the fact that in Iran economy, deviations and imbalances have arisen in the agricultural sector TFP caused by technology spillovers shocks, move very fast towards long-run equilibrium. Conclusions: The purpose of this paper is to advance the knowledge for a key question with evident implications for economic policy: What is the

  5. Sector-based political analysis of energy transition: Green shift in the forest policy regime in France

    International Nuclear Information System (INIS)

    Sergent, Arnaud

    2014-01-01

    This article examines energy transition political process from a sector-based approach, through the analysis of recent shift in the French forest policy regime. We demonstrate that, since 2007, energy transition policies have led to a harvesting turn within the French forest policy framework, meaning that priority is given to wood mobilisation, mainly for biomass uses. In addition, our findings suggest that the political authority wielded by the state over forest policy has shifted from forest administrative services to energy agencies and local authorities. Finally, we show that, although implementation of the harvesting turn is a cause of sectoral and inter-sectoral tensions, energy transition challenge also contributes to a process of (re)institutionalisation of mediation relationships among forestry stakeholders and wood-based industries representatives. The article concludes by arguing that sectors should retain relevant institutional frameworks for actors when choosing political arrangements required for implementing energy transition policy. - Highlights: • Implementing energy transition policy potentially challenges sector-based politics. • We propose a policy regime framework and socio-political investigations. • We analyse the political impact of energy transition policy on French forest sector. • Shifts occur in sectoral policy framework, authority, and mediation relationships

    2007-03-01

    Full Text Available Using 1024 nights of data from 2002–2005 taken by the Cornell Narrow Field Imager (CNFI, we examine equatorial plasma bubble (EPB zonal drift velocity characteristics. CNFI is located at the Maui Space Surveillance Site on the Haleakala Volcano (geographic: 20.71° N, 203.83° E; geomagnetic: 21.03° N, 271.84° E on the island of Maui, Hawaii. The imager is set up to view in a magnetic field-aligned geometry in order to maximize its resolution. We calculate the zonal drift velocities using two methods: a correlation routine and an EPB west-wall intensity gradient tracking routine. These two methods yield sizeable differences in the evenings, suggesting strong pre-local midnight EPB development. An analysis of the drift velocities is also performed based on the three influencing factors of season, geomagnetic activity, and solar activity. In general, our data match published trends and drift characteristics from past studies. However, we find that the drift magnitudes are much lower than results from other imagers at similar latitude sectors but at different longitude sectors, suggesting that zonal drift velocities have a longitudinal dependence.

    Gradual environmental degradation, shrinking of non-renewable resources, and lower quality of life are directly or indirectly arising from snowballing consumption. These unfavorable processes concern increasingly textile and clothing sector and are increasingly being felt in Visegrad Region (V4). The objective of the article was to access current consumption patterns in V4 countries, identify the factors that influence those patterns and finally to draw the conclusions for more sustainable consumption and production models as well as to make a comparative analysis of the results across V4 countries. A consumer survey was conducted to examine V4 citizens’ attitudes and behaviors in the context of sustainable consumption. To ensure sample size and comparability across countries 2000 randomly-selected V4 citizens, aged 18 and over, were interviewed. To analyze the supply side of the market and legal framework, the desk research was used. The results allowed to give some guidelines for the joint V4 strategy for solving ecological and social problems of V4 countries as well as the conclusions for textile and clothing sector.

    Kang, Jidong; Zhao, Tao; Liu, Nan; Zhang, Xin; Xu, Xianshuo; Lin, Tao

    2014-01-01

    To better understand how city-level greenhouse gas (GHG) emissions have evolved, we performed a multi-sectoral decomposition analysis to disentangle the GHG emissions in Tianjin from 2001 to 2009. Five sectors were considered, including the agricultural, industrial, transportation, commercial and other sectors. An industrial sub-sector decomposition analysis was further performed in the six high-emission industrial branches. The results show that, for all five sectors in Tianjin, economic growth was the most important factor driving the increase in emissions, while energy efficiency improvements were primarily responsible for the decrease in emissions. In comparison, the influences from energy mix shift and emission coefficient changes were relatively marginal. The disaggregated decomposition in the industry further revealed that energy efficiency improvement has been widely achieved in the industrial branches, which was especially true for the Smelting and Pressing of Ferrous Metals and Chemical Raw Materials and Chemical Products sub-sectors. However, the energy efficiency declined in a few branches, e.g., Petroleum Processing and Coking Products. Moreover, the increased emissions related to industrial structure shift were primarily due to the expansion of Smelting and Pressing of Ferrous Metals; its share in the total industry output increased from 5.62% to 16.1% during the examined period. - Highlights: • We perform the LMDI analysis on the emissions in five sectors of Tianjin. • Economic growth was the most important factor for the emissions increase. • Energy efficiency improvements mainly contributed to the emission decrease. • Negative energy intensity effect was observed in most of the industrial sub-sectors. • Industrial structure change largely resulted in emission increase

    Although mammography is the main diagnostic method for breast cancer, but the interpretation of mammograms is a difficult task and depends on the experience and skill of the radiologists. Computer Aided Detection (CADe) systems have been proposed to help radiologist in interpretation of mammograms. In this paper a novel filter called Sector filter is proposed to detect masses. This filter works based on the analysis of convergence of gradient vectors toward the center of filter. Using this filter, rounded convex regions, which are more likely to be pertained to a mass, could be detected in a gray scale image. After applying this filter on the images with two scales and their linear combination suspicious points were selected by a specific process. After implementation of the proposed method, promising results were achieved. The performance of the proposed method in this research was competitive or in some cases even better than that of other suggested methods in the literature. (authors)

    In this paper, we compare five popular systemic risk rankings, and apply principal component analysis (PCA) model to provide a stable systemic risk ranking for the Chinese banking sector. Our empirical results indicate that five methods suggest vastly different systemic risk rankings for the same bank, while the combined systemic risk measure based on PCA provides a reliable ranking. Furthermore, according to factor loadings of the first component, PCA combined ranking is mainly based on fundamentals instead of market price data. We clearly find that price-based rankings are not as practical a method as fundamentals-based ones. This PCA combined ranking directly shows systemic risk contributions of each bank for banking supervision purpose and reminds banks to prevent and cope with the financial crisis in advance.

    Full Text Available Al analizar el sector azucarero y el etanol del Valle del Cauca se pretende demostrar que de seguir el precio internacional del azúcar por encima de 16 centavos de dólar la libra, la industria azucarera contaría con mecanismos de coordinación que le permitirán direccionar su producción de caña de azúcar hacia este eslabón de la cadena productiva por ser el que mayor margen de utilidad le produce, sin tener que aumentar la cantidad de hects sembradas de manera proporcional al incremento del azúcar exportada. Cuestión que consolido al sector azucarero como uno de los dinamizadores de la economía colombiana, pero a la fecha ha obligado al gobierno a rebajar el porcentaje de alcohol carburante en la gasolina del 10 al 8% y crea dudas sobre el cumplimiento de los decretos que incrementan de manera sustancial el porcentaje de alcohol carburante para los motores de 2000 cms³.Analysis of the sector tries to demonstrate that following the international price of sugar above 16 cents a pound, the sugar industry will count on coordinating mechanisms that will allow them to direct their production of cane sugar to the link in the productive chain which will produce the greatest profit margin will produce, without having to increase the number of acres planted in proportion to the increase in sugar exported. This consolidated the sugar industry as one of the driving forces of the Colombian economy, but to date has forced the government to lower the percentage of ethanol fuel in gasoline from 10 to 8 percent and casts doubt on the implementation of decrees which substantially increase the percentage of alcohol fuel for engines of 2000 cms³.

    To investigate the driving forces of air pollution in China, the changes in linkages amongst inter-industrial air pollutant emissions were analyzed by hypothetical extraction method under the input-output framework. Results showed that the emissions of SO 2 , soot and dust from industrial sources increased by 56.46%, 36.95% and 11.69% respectively in 2010, compared with 2002. As major contributors to emissions, the power and gas sectors were responsible for the growing SO 2 emissions, the nonmetal products sector for soot emissions, and the metals mining, smelting and pressing sectors for dust emissions. The increasing volume of emissions was mainly driven by the growing demand in the transport equipment and electrical equipment sectors. In addition, the expansion in the metals mining, smelting and pressing sectors could result in even more severe air pollution. Therefore, potential effective strategies to control air pollution in China are: (1) reducing the demand of major import sectors in the equipment manufacturing industry; (2) promoting R&D in low-emissions-production technologies to the power and gas sectors, the metals mining, smelting and pressing sectors, and the nonmetal products sector, and (3) auditing the considerable industrial scale expansion in the metals mining, smelting and pressing sectors and optimizing the industrial structure.

    An energy security index was developed to measure how the introduction of nuclear power generation improved the national security of energy supply in Korea. Using the developed index, a quantitative effort was made to analyze the relationship between the nuclear power generation and the national energy security. Environmental impacts were evaluated and a simplified external cost of a specific coal-fired power plant in Korea was estimated using the QUERI program, which was developed by IAEA. In doing so, efforts were made to quantify the health impacts such as mortality, morbidity, and respiratory hospital admissions due to particulates, SOx, and Nox. The effects of CO 2 emission regulation on the national economy were evaluated. In doing so, the introduction of carbon tax was assumed. Several scenarios were established about the share of nuclear power generation and an effort was made to see how much contribution nuclear energy could make to lessen the burden of the regulation on the national economy. This study re-evaluated the methods for estimating and distributing decommissioning cost of nuclear power plant over lifetime. It was resulted out that the annual decommissioning deposit and consequently, the annual decommissioning cost could vary significantly depending on estimating and distributing methods.

    1992-01-01

    The concept of spatial equilibrium prices for electricity is presented based on incremental generating costs and transmission costs between major generating and load centers, which may be individual generators, utilities or countries. The equilibrium price changes in time and space, with the important property that these prices, if used for trading of electricity, results in all loads being served at minimal total cost. A network modeling approach for determining optimal operation of an interconnected system of utilities and independent generators simultaneously calculates these equilibrium prices. The methodology determines optimal generation by each utility, transactions between them, and the flows in the transmission network. 11 refs., 3 figs

    Full Text Available In this paper we analyze and highlight the evolution of workforce engaged in the secondary sector. We determined too the unemployment rate distribution, which is coupled with the decline of industry and constructions and there are identified zones and cities affected by major rising unemployment. The increase of unemployed number in the secondary sector was primarily due to the decline of manufacturing industry and mining. At Bucharest and growth poles level, it shows that between the secondary sector branches: industry and construction, the most employees are engaged in the industrial sector, especially in manufacturing industries, although this sector ranks on the second place in order of preference. Most of the employees choose jobs into the tertiary sector. Regarding the distribution of the number of employees per industrial subsectors, it appears that most of them work in manufacturing, followed water supply and waste, then energy supply and a very small percentage in the mining. The activity sectors reveal that most employees are engaged in secondary and tertiary sectors, and then, in a very small proportion, in the primary sector. At regional poles level, the largest number of employees are engaged in industrial sector. In the construction sector, the number of employees is small. Counties associated of Bucharest metropolitan area recorded the greatest number of employees in construction. All analyzed territories recorded positive evolutions in the number of employees in 2011 compared to 2002. Counties associated of some metropolitan areas, including Bucharest, showed a positive trend, superior to other types of areas in 2011 compared to 2002. Compared to the situation in construction sector, the industry is characterized by a decrease of the number of employees in 2011 compared to 2002. Even in a general context characterized by instability in the industry, some types of analyzed areas showed a rising trend. In 2011, compared to 2006

    This paper aims to investigate the sectoral energy use in the Turkish economy for the 1980-2000 period when significant changes occurred in the economic and demographic structure of the country. These changes had several impacts on the energy use in the primary sectors such as agriculture, industry and services. Decomposition analysis is conducted on these sectors by using the additive version of the LMDI method due to its advantages over others. Although a close relationship exists between primary energy consumption and GDP, analyses show that significant variations occurred in the sectoral energy use during the 1982, 1988-1989, 1994 and 1998-2000 periods. Such variations are related to the economic policies of the governments. The Turkish economy has undergone a transformation from agricultural to industrial enhanced by rapid urbanization, especially after 1982. However, industrialization has not been completed yet, and the energy demand should be increasing faster than national income until the energy intensity of the country reaches a peak. This study is performed on three basic sectors; however, decomposition into secondary and tertiary sectors will provide detailed information for further investigations

    Full Text Available The bio-based economy will be crucial in achieving a sustainable development, covering all ranges of natural resources. In this sense, it is very relevant to analyze the economic links between the bioeconomic sectors and the rest of the economy, determining their total and decomposed impact on economic growth. One of the major problems in carrying out this analysis is the lack of information and complete databases that allow analysis of the bioeconomy and its effects on other economic activities. To overcome this issue, disaggregated social accounting matrices have been obtained for the highly bio-based sectors of the 28 European Union member states. Using this complex database, a linear multiplier analysis shows the future key role of bio-based sectors in boosting economic development in the EU. Results show that the bioeconomy has not yet unleashed its full potential in terms of output and job creation. Thus, output and employment multipliers show that many sectors related to the bioeconomy are still underperforming compared to the EU average, particularly those with higher value added; although, they are still crucial sectors for the wealth creation.

    We describe a framework for model-based analysis and test case generation in the context of a heterogeneous model-based development paradigm that uses and combines Math- Works and UML 2.0 models and the associated code generation tools. This paradigm poses novel challenges to analysis and test case generation that, to the best of our knowledge, have not been addressed before. The framework is based on a common intermediate representation for different modeling formalisms and leverages and extends model checking and symbolic execution tools for model analysis and test case generation, respectively. We discuss the application of our framework to software models for a NASA flight mission.

    Full Text Available Industrial energy and environment efficiency evaluation become especially crucial as industrial sectors play a key role in CO2 emission reduction and energy consumption. This study adopts the additive range-adjusted measure data envelope analysis (RAM-DEA model to estimate the low-carbon economy efficiency of Chinese industrial sectors in 2001–2013. In addition, the CO2 emission intensity mitigation target for each industrial sector is assigned. Results show that, first, most sectors are not completely efficient, but they have experienced and have improved greatly during the period. These sectors can be divided into four categories, namely, mining, light, heavy, and electricity, gas, and water supply industries. The efficiency is diverse among the four industrial categories. The average efficiency of the light industry is the highest among the industries, followed by those of the mining and the electricity, gas, and water supply industries, and that of the heavy industry is the lowest. Second, the electricity, gas, and water supply industry shows the biggest potential for CO2 emission reduction, thus containing most of the sectors with large CO2 emission intensity mitigation targets (more than 45%, followed by the mining and the light industries. Therefore, the Chinese government should formulate diverse and flexible policy implementations according to the actual situation of the different sectors. Specifically, the sectors with low efficiency should be provided with additional policy support (such as technology and finance aids to improve their industrial efficiency, whereas the electricity, gas, and water supply industry should maximize CO2 emission reduction.

    Full Text Available Design and implementation of strategy is the backbone of the business enterprise. Strategic management process begins by establishing the vision and mission. Therefore, they are important components of further development of the overall company strategy. Following the above, we can conclude that it is of paramount importance to set a quality statement about the vision and mission to develop strategies in a positive direction, being at the same time comprehensible and stimulating to all target groups. Economic development divides activities in four different sectors (primary, secondary, tertiary and quaternary. Each sector has its own specifics, which become a key component of differentiation of that sector in relation to others. Therefore, it can be assumed that the company's strategy within each sector is set in accordance with sector specifics. On the basis of the above mentioned facts we come to a conclusion that there are key components that are company’s strategies specific for each sector, which also differentiate strategy compared to strategies of other sectors. The aim of this paper is to find specific components to develop a strategy for each sector, and key components of inter-sectoral differentiation in setting the vision and mission.

    The existence of anti competitive conduct such as cartels would lead to a situation of high prices and profits harming competition and society in general. The methodology of economic analysis of evidence of cartel by the ANP in the resale market of fuels involves analysis of the behavior of the average prices of resale and distribution, the nominal average gross margin on resale, the coefficient of variation of prices of resale and distribution of fuel for a given period by the municipality. Combining the analysis of these elements, the ANP has suggested the investigation into possible cartels. This text aims to bring contributions for a better definition of the relevant market in the analysis of economic evidence in cartel in the market for resale of fuel and add elements currently not considered in the analysis of ANP and regulation of the sector.

    Li, Fangyi; Song, Zhouying; Liu, Weidong

    2014-01-01

    It is now widely recognized that there is a strong relationship between energy consumption and economic growth. Most countries′ energy demands declined during the economic depression of 2008–2009 when a worldwide economic crisis occurred. As an export-oriented economy, China suffered a serious exports decline in the course of the crisis. However, it was found that energy consumption continued to increase. Against such a background, this paper aims to assess and explain the factors causing the growth of energy consumption in China. First, we will explain the impact of domestic final use and international trade on energy consumption by using decomposition analysis. Second, embodied energy and its variation across sectors are quantified to identify the key sectors contributing to the growth. Lastly, the policy implications for long-term energy conservation are discussed. The results show that the decline in exports was one of the driving forces for energy consumption reduction in the crisis, but that the growth of domestic demand in manufacturing and construction, largely stimulated by economic stimulus plans, had the opposite effect on energy consumption. International trade contributed to decreasing energy consumption of China during and after the crisis because the structure of exports and imports changed in this period. - Highlights: • We analyze the reasons for China's energy consumption change under the global economic crisis during 2007–2010. • Domestic final use growth, especially in construction and manufacturing of machinery and equipment, resulted in energy consumption increase. • International trade is identified as a driver of energy consumption reduction during and after the crisis. • Increasing China's share of consumption or reducing its share of investment in the GDP can reduce national energy intensity

  1. A COMPARATIVE ANALYSIS OF CERTIFICATION SCHEMES IN THE BRAZILIAN FRUIT SECTOR

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Certification has become increasingly relevant as a marketing signal for agribusiness especially in the fruit sector over the past few years. Substantial parts of many value chains are by now certified by standards as GlobalGAP, Fair Trade, Integrated Fruit Production and Organic. At the same time, in developed countries, particularly in the European Union and the United States, demand for higher levels of food safety has led to the implementation of certification programs that address more types of safety-related attributes and impose stricter standards. Certification systems play an important role in any market that is burdened with a high degree of information asymmetry and quality uncertainty. Thus, producers and exporters of fresh fruit and vegetables from developing countries like Brazil are increasingly required to demonstrate the safety and traceability of their produce up to the consumption stage. The comparative analysis of the four certification schemes which exist in the fruit sector in Brazil has shown that GlobalGAP and the Integrated Fruit Production (PIF are similar certification schemes. However, they differ with respect to the number of requirements and their distribution over various stages (e.g. production, post-harvesting. Contrary to PIF and GlobalGAP, Fairtrade certification concentrates on producers’ organizations and cooperatives where small-scale farmers belong to and not on individual farmers. In addition, a lot of attention is paid to the labour and environmental conditions, besides the guarantee of a minimum price for farmers. With respect to organic certification, the requirements are not directed to a particular product or crop and their level of compliance is not indicated. Major emphasis is put on the production system. Organic and Fairtrade certification do not have an own book keeping for records.

    In this article, we decomposed Korean industrial manufacturing greenhouse gas (GHG) emissions using the log mean Divisia index (LMDI) method, both multiplicatively and additively. Changes in industrial CO 2 emissions from 1991 to 2009 may be studied by quantifying the contributions from changes in five different factors: overall industrial activity (activity effect), industrial activity mix (structure effect), sectoral energy intensity (intensity effect), sectoral energy mix (energy-mix effect) and CO 2 emission factors (emission-factor effect). The results indicate that the structure effect and intensity effect played roles in reducing GHG emissions, and the structure effect played a bigger role than the intensity effect. The energy-mix effect increased GHG emissions, and the emission-factor effect decreased GHG emissions. The time series analysis indicates that the GHG emission pattern was changed before and after the International Monetary Fund (IMF) regime in Korea. The structure effect and the intensity effect had contributed more in emission reductions after rather than before the IMF regime in Korea. The structure effect and intensity effect have been stimulated since the high oil price period after 2001. - Highlights: • We decomposed greenhouse gas emissions of Korea's manufacturing industry using LMDI. • The structure effect and intensity effect play a role in reducing GHG emissions. • The role of structure effect was bigger than intensity effect. • The energy-mix effect increased and the emission-factor effect decreased GHG emissions. • The GHG emission pattern has been changed before and after IMF regime in Korea

    This article analyses the cause–effect relation of the structural reform in the Mexican electricity sector, called the Public Electricity Service Act, from 1992 to 2009. One of the main arguments of the reform is to attract private investment in order to reduce the financial load of the government in infrastructure for the development of the National Electric Power System by means of six modalities (Power Self-Supply, Cogeneration, Small Power Production, Independent Power Production, Power Export and Power Import). The article presents the global context of reforms adopted in 1990. The major policies and events are presented in chronological order (before and after reform). In addition, it analyses the new institutional framework, the evolution of modalities, technologies of electricity generation and tariffs. The main conclusion is that the result of reform could be considered a partial progress. The Independent Power Production modality shows greater participation, while Power Self-Supply and Cogeneration are lower. The subsidy policy is maintained. Progress is needed in policies and strengthening, and also in updating regulatory and normative frameworks

    In this paper it is assessed the potential economic impact of an industrial initiative in the photovoltaic manufacturing sector, in terms of induced production and job creation, to be implemented in Morocco. This country exhibits indeed a high potential for photovoltaic installations as proved by the relevant number of national and international deployment programs currently underway. Solar electricity generation schemes look very promising for the relevant role they could play in the future, CO2-emission free, world energy scenarios making potentially more appealing the planning of longer-term public investments. In this study, it was described the manufacturing process providing the solar modules as final output and associate to each step of the process the corresponding costs. Then, using input-output method, it was evaluated the economic impact of the production of 5 MWp modules a year under different hypotheses. A production of 5MWp photovoltaic modules, which require an overall investment of Euro 16.3 millions increases gross domestic product of Euro 57.6 millions if cells are locally produced and only of Euro 22.3 millions when the cells are imported, creating 2570 and 489 jobs, respectively. These results outline the importance of availability of inputs in local economical context [it

    Environmental regulations in Mexico could dramatically increase demand for natural gas in the following years. This increase could lead to gas price shocks and a counter-intuitive increase in carbon emissions. The effect would be accentuated if Mexico lacks the funds required to carry on with investments in gas development and processing capacity. With the use of a dynamic computer model, this study addresses responses of the Mexican oil and gas industries to perturbations such as: changes in regulatory and environmental policies; changes in institutional arrangements such as those arising from market liberalization; and lack of availability of investment funds. The study also assesses how regulatory policies can be designed to minimize the economic inefficiencies arising from the business cycle disruptions that some perturbations may cause. In addition, this study investigates how investment responses will shape the Mexican energy sector in the future, particularly with respect to both the relative importance of different fuels for power generation and heating purposes and the nature of competition in the Mexican natural gas market. Furthermore, this study explores the direct consequences of these responses on the level of carbon emissions. (Author)

    Studies on the consumption of energy by an ozone generator with various constructions electrodes of dielectric barrier discharge plasma (DBDP) reactor has been carried out. This research was done to get the configuration of the reactor, that is capable to produce high ozone concentrations with low energy consumption. BDBP reactors were constructed by spiral- cylindrical configuration, plasma ozone was generated by high voltage AC voltage up to 25 kV and maximum frequency of 23 kHz. The reactor consists of an active electrode in the form of a spiral-shaped with variation diameter Dc, and it was made by using copper wire with diameter Dw. In this research, we variated number of loops coil windings N as well as Dc and Dw. Ozone concentrations greater when the wire's diameter Dw and the diameter of the coil windings applied was greater. We found that impedance greater will minimize the concentration of ozone, in contrary to the greater capacitance will increase the concentration of ozone. The ozone concentrations increase with augmenting of power. Maximum power is effective at DBD reactor spiral-cylinder is on the Dc = 20 mm, Dw = 1.2 mm, and the number of coil windings N = 10 loops with the resulting concentration is greater than 20 ppm and it consumes energy of 177.60 watts (paper)

    A computer model for the prediction of flow and temperature fields within a fast reactor steam generator unit is described. The model combines a commercially available computational fluid dynamics (CFD) solver (PHOENICS) with a steam-tube calculation and provides solutions for the fully coupled flow and temperature fields on both the shell side and the tube side. The model includes the inlet and outlet headers and the bottom end stagnant zone. It also accounts for the effects of support grids and edge-gaps. Two and three dimensional and transient calculations have been performed for both straight tube and J-tube units. Examples of the application of the model are presented. (7 figures) (Author)

    Operating more than 30 PWR units, Electricite de France has to face several steam generator tube problems. One of the most serious difficulties is the stress corrosion cracking due to primary fluid, just above the tube sheet, in the roll transition region. With regard to availability it is, of course, a major concern; with regard to safety, the point is that tube rupture should be preceded by a significant primary-to-secondary leak during normal operation so that the reactor should be shut down before failure occurs. The demonstration of this assessment asks for experimental and analytical evidences. In 1981, Elecricite de France started a comprehensive program on that subject. A general description of this program and the main results are to be presented during the SMIRT-8 Conference. The purpose of the present paper is to develop in greater detail the analytical part of the work

    The enormous amount of data collected by the B factories as well as the perspective concerning the upcoming experiments at the LHC provide us with the opportunity to perform high precision tests of the standard model. This dissertation presents two model independent precision tests of the weak sector of the standard model using extensions of the weak currents which are set up using effective field theory methods in order to control the size of the different contributions. Constraints on the coefficients of the terms can then be obtained by comparison with experimental results. The first analysis incorporates a test of the lefthandedness of the weak interaction in the quark sector. By introducing additional weak couplings the differential and total decay rates of the inclusive semileptonic decay anti B → X c l anti ν l are calculated. The calculation includes the computation of the heavy-quark expansion which describes the interaction of the decaying b quark with respect to the background field of the B meson, up to order 1/m b 4 . This has been done in a new, systematic way which does not involve the calculation of gluon matrix elements. Furthermore, radiative corrections have been included up to order O(α s ) including renormalization group running. The second part deals with the introduction of lepton flavor violating operators in the context of leptonic τ decays. These operators give rise to the effective four-fermion vertex τ→ll ' l'' as well as the subsequent radiative decay τ→lγ * →ll '+ l '- . The resulting Dalitz distributions turn out to predict completely different signatures for the radiative and the effective four-fermion vertices and provide the opportunity to check, whether the decay is induced either by a radiative or by an effective four-fermion vertex. Since different models which contain lepton flavor violation are normally more sensitive to one of those decay modes than to the other, the analysis therefore allows the comparison of

    Full Text Available In typical buildings, air conditioners have the biggest percentage in energy consumption among all sectors. It makes a good management for air conditioners is needed and important in order to use the energy efficiently. Having a very hot and humid weather, it gives impact that most of buildings in Surabaya installed air conditioners, including Surabaya City Government office buildings. However, there is no regulation nor guidance how to manage air conditioners in Surabaya City Government, while Surabaya itself has a goal to become a green-eco city. Then, the existing condition of air conditioners usage in Surabaya Government units (SKPDs is evaluated. The evaluation resulted that most of air conditioners were over capacity and not all of them were efficient in energy consumption. Therefore, a need analysis is required to help Surabaya City Government managing its air conditioners better. By applying two different concepts, one is based on the architectural view and another one is based on green building criteria, the existing condition is analyzed and two procedures of need analysis are produced. The procedures can be implemented for two different conditions of office building rooms in Surabaya City Government.

    Full Text Available The aim of this study is to compute the overall effect size concerning the impact of insurance sector activity on economic growth. The connection of insurance activity and economic growth has been a widely investigated topic due to numerous papers and research attempts performed so far. The results, however, often differ among individual studies. Therefore a comprehensive analysis of the significance of causality from insurance activity, measured by insurance premium, to business cycle fluctuation, is well-required. Using 10 published and unpublished studies, we conduct a meta-analysis of the literature on the impact of insurance activity on economic growth. Insurance premium is taken as the measure of insurance activity. The combined significance test of individual t-statistics is employed. The calculation of the effect size allows understand the true effect relying on synthesis of so far published research with significantly higher amount of observations and better precision. Our results confirm positive effect of insurance activity on economic growth and are particularly important for policy makers who set the policy towards subjects in the insurance market.

    Results of the 1993 Greenhouse Gas Emissions Inventory of The Gambia showed net CO{sub 2} emissions of over (1.66 x 10{sup 6} tons) and 1% was due to uptake by plantations (0.01 x 10{sup 6} tons). This is a clear indication that there is need to identify changes in the land-use policy, law and tenure that discourages forest clearing at the same time significantly influencing the sustainable distribution of land among forestry, rangeland and livestock, and agriculture. About 11% of the total area of The Gambia is either fallow or barren flats that once supported vegetation and hence is still capable of supporting vegetation. The US Country Study Programme has provided the Government of The Gambia through the National Climate Committee funds to conduct Assessment of Mitigation Options to Reduce Greenhouse Gas Emissions. The Forestry Sector is one area for which assessment is being conducted. The assessment is expected to end in September 1996. The Comprehensive Mitigation Analysis Process (COMAP) is one of the Models supplied to the National Climate Committee by the Lawrence Berkeley Laboratory, on behalf of the US Country Study Programme, and is being used to conduct the analysis in The Gambia.

    2007-12-17

    SEADS 3.0, the Sectoral Energy/Employment Analysis and Data System, is a revision and upgrading of SEADS--PC, a software package designed for the analysis of policy that could be described by modifying final demands of consumer, businesses, or governments (Roop, et al., 1995). If a question can be formulated so that implications can be translated into changes in final demands for goods and services, then SEADS 3.0 provides a quick and easy tool to assess preliminary impacts. And SEADS 3.0 should be considered just that: a quick and easy way to get preliminary results. Often a thorough answer, even to such a simple question as, “What would be the effect on U. S. energy use and employment if the Federal Government doubled R&D expenditures?” requires a more sophisticated analytical framework than the input-output structure embedded in SEADS 3.0. This tool uses a static, input-output model to assess the impacts of changes in final demands on first industry output, then employment and energy use. The employment and energy impacts are derived by multiplying the industry outputs (derived from the changed final demands) by industry-specific energy and employment coefficients. The tool also allows for the specification of regional or state employment impacts, though this option is not available for energy impacts.

    Full Text Available The aim of this paper is the detection and analysis of empirical determinants of credit risk in the banking sector of the Republic of Serbia. The paper is based on an analysis of results of the application of the linear regression model, during the period from the third quarter of 2008 to the third quarter of 2014. There are three main findings. Firstly, the higher lending activity of banks contributes to the increasing share of high-risk loans in the total withdrawn loans (delayed effect of 3 years. Secondly, the growth of loans as opposed to deposits contributes to the increased exposure of banks to credit risk. Thirdly, the factors that reduce the exposure of banks to credit risk increase profitability, growth of interest rate spread and real GDP growth. Bearing in mind the overall market conditions and dynamics of the economic recovery of the country, there is a general conclusion based on the results that in the coming period the question of non-performing loans (NPLs in the Republic of Serbia will present a challenge for both lenders and borrowers.

    2010-05-01

    Full Text Available Permanent magnet DC motor-generators (PMDC, PMSG have been widely used in industrial and energy sectors recently. Power control of these systems can be achieved by controlling the output voltage. In this study, PMDC-PMSG systems are mathematically modeled and simulated in MATLAB and Simulink software. Then the results are discussed. A low power permanent magnet synchronous generator is driven by a permanent magnet DC motor and the output voltage is controlled by a frequency cycle-converter. The output of a half-wave uncontrolled rectifier is applied to an SPWM inverter and the power is supplied to a 300V, 50Hz load. The load which is connected to an LC filter is modeled by state-space equations. LC filter is utilized in order to suppress the voltage oscillations at the inverter output.

    The aim of this study was to gain insight in the importance of job demands and resources and the validity of the Job Demands Resources Model across sectors. We used one-way analyses of variance to examine mean differences, and multi-group Structural Equation Modeling analyses to test the strength of the relationships among job demands, resources, burnout, and work engagement across the health care, industry, service, and public sector. The four sectors differed in the experience of job demands, resources, burnout, and work engagement, but they did not vary in how (strongly) job demands and resources associated with burnout and work engagement. More attention is needed to decrease burnout and increase work engagement, particularly in industry, service, and the public sector. The Job Demands-Resources model may be helpful in this regard, as it is valid across sectors.

    Energy is an engine for growth and is linked with all aspects of development, poverty alleviation, and improvement of quality of life. The production, distribution and use of energy particularly fossil fuels have significant environmental impacts. Pakistan has total power generation capacity of 19.25 GW, with 63.9% thermal, 33.7% hydel and 2.4% nuclear share. The electricity generation increased by 7.5% per annum during the last three decades and future demand has been projected to grow at 7%-11 % per annum. This increasing power demand will depend mainly on power generation from fossil fuels. This paper presents the review of power generation situation and assesses the air pollution emissions from thermal power generation in Pakistan. The paper also investigates the prospects of renewable energy- sources for air pollution mitigation in the country. The study indicates that thermal power generation plants are the major source of air pollution emissions in the country. This air pollution has local, regional and global environmental impacts. The paper concludes that the use of renewables such as hydel, wind, solar and biomass energy for power generation can contribute substantially in air pollution mitigation in the country. (author)

    As a follow-up to the phenomena identification and ranking table (PIRT) studies conducted recently by NRC on next generation nuclear plant (NGNP) safety, a study was conducted to identify the significant 'gaps' between what is needed and what is already available to adequately assess NGNP safety characteristics. The PIRT studies focused on identifying important phenomena affecting NGNP plant behavior, while the gap study gives more attention to off-normal behavior, uncertainties, and event probabilities under both normal operation and postulated accident conditions. Hence, this process also involved incorporating more detailed evaluations of accident sequences and risk assessments. This study considers thermal-fluid and neutronic behavior under both normal and postulated accident conditions, fission product transport (FPT), high-temperature metals, and graphite behavior and their effects on safety. In addition, safety issues related to coupling process heat (hydrogen production) systems to the reactor are addressed, given the limited design information currently available. Recommendations for further study, including analytical methods development and experimental needs, are presented as appropriate in each of these areas.

    This paper provides quantitative information for energy consumption from four different industry sectors based on an energy analysis obtained by means of in-situ energy audits and complementary information. The latter information was taken from Saving Strategy and Energy Efficiency in Spain (Estrategia de Ahorro y Eficiencia Energética en España 2004–2010, E4) documents and the 2009 Industrial Survey of Spain from the National Statistics Institute (Instituto Nacional de Estadística, INE). The results show an estimate of energy consumption for each sector, namely Spanish food, drink and tobacco (9.6%), textile (4.5%), chemical (14.7%), and non-metallic mineral products (24.3%), as well as the degree of inefficiency for each, obtained by means of a stochastic frontier production function model. These results are combined with the energy consumption analysis to identify potential energy saving opportunities around 20.0% of the total energy consumption for all studied sectors. These energy saving opportunities are classified according to thermal or electrical energy consumption and percentage savings of the total energy consumption. -- Highlights: ► This study presents the analysis of four Spanish energy-consuming industrial sectors. ► The four selected sectors account for 33.0% of the total industrial SMEs. ► An audit was carried out in several factories from each analysed industrial sector. ► Stochastic Cobb-Douglas frontiers were used to estimate production frontiers. ► Potential energy saving opportunities around 20.0% of the total energy consumption.

    This paper presents a focused analysis of the role of entrants into the electricity generation market since privatisation. It examines subsequent developments in the market and in the industry's structure and performance. The analysis draws heavily upon new information gained from telephone interviews with many of those involved with the so-called 'independent power producers' (IPPs), as well as information in the existing literature. Our key finding is that IPP entry has not significantly increased competition and has adversely affected the future viability of the electricity system. We attribute these failures to the very policies that encouraged the initial entry of the IPPs

    International Nuclear Information System (INIS)

    1985-01-01

    As a long range goal for the production of high intensity neutrons, Argonne National Laboratory has proposed the construction of a 1.5 GeV FFAG Spiral Sector Accelerator called ASPUN. The 500-MeV injector for this proposed accelerator is a smaller FFAG Spiral Sector Accelerator named Mini-ASPUN. Until such a time as the larger machine could be built, it was planned that Mini-ASPUN would replace the present RCS now being used for the IPNS program at Argonne. In order to obtain an accurate estimation of the orbits and betatron oscillations in such a machine, it is necessary that realistic field values be used in the equations of motion. Obtaining these fields from 3-dimensional relaxation calculations is both time consuming and costly. However, because of the required scaling of the machine, the field-generating potential of three variables can be separated into a known function of the radius and a function of two variables. The second order differential equation satisfied by this function can be solved by ordinary relaxation methods. The fields generated from a mesh of values for this function will be accurate except for the extreme inside and outside orbits, which will be affected by the necessary termination of the inside and outside ends of the magnet. 2 refs., 4 figs., 1 tab

    This paper estimates the weak-form efficiency of Islamic stock markets using 10 sectoral stock indices (basic materials, consumer services, consumer goods, energy, financials, health care, industrials, technology, telecommunication, and utilities). The results based on the multifractal detrended fluctuation analysis (MF-DFA) approach show time-varying efficiency for the sectoral stock markets. Moreover, we find that they tend to show high efficiency in the long term but moderate efficiency in the short term, and that these markets become less efficient after the onset of the global financial crisis. These results have several significant implications in terms of asset allocation for investors dealing with Islamic markets.

    To identify competencies important for effective nursing management and to assess managers' proficiency therein. A lack of management capacity has been identified as the key stumbling block to health delivery in South Africa. Despite nursing managers being central to overcoming the challenges facing health care, there has been a paucity of research that empirically evaluates their skill levels. A survey was conducted among 171 senior nursing managers in South Africa using a self-administered questionnaire. Public sector managers assessed themselves as being relatively less competent than private sector managers. The largest skill gaps for public sector managers were for 'ethico-legal', 'task-related' and 'controlling' skills whereas those for private sector managers were for 'ethico-legal', 'health-related ' and 'task-related' skills. This research confirmed the lack of management capacity within the health sector and identified areas in which the skills deficit was most significant for both the public and private sectors. These findings reflect the needs of nursing managers and will be useful in the conceptualization, design and delivery of health management programmes aimed at enhancing management and leadership capacity in the health sector in South Africa.

    Human water withdrawal has increasingly altered the global water cycle in past decades, yet our understanding of its driving forces and patterns is limited. Reported historical estimates of sectoral water withdrawals are often sparse and incomplete, mainly restricted to water withdrawal estimates available at annual and country scales, due to a lack of observations at seasonal and local scales. In this study, through collecting and consolidating various sources of reported data and developing spatial and temporal statistical downscaling algorithms, we reconstruct a global monthly gridded (0.5°) sectoral water withdrawal dataset for the period 1971-2010, which distinguishes six water use sectors, i.e., irrigation, domestic, electricity generation (cooling of thermal power plants), livestock, mining, and manufacturing. Based on the reconstructed dataset, the spatial and temporal patterns of historical water withdrawal are analyzed. Results show that total global water withdrawal has increased significantly during 1971-2010, mainly driven by the increase in irrigation water withdrawal. Regions with high water withdrawal are those densely populated or with large irrigated cropland production, e.g., the United States (US), eastern China, India, and Europe. Seasonally, irrigation water withdrawal in summer for the major crops contributes a large percentage of total annual irrigation water withdrawal in mid- and high-latitude regions, and the dominant season of irrigation water withdrawal is also different across regions. Domestic water withdrawal is mostly characterized by a summer peak, while water withdrawal for electricity generation has a winter peak in high-latitude regions and a summer peak in low-latitude regions. Despite the overall increasing trend, irrigation in the western US and domestic water withdrawal in western Europe exhibit a decreasing trend. Our results highlight the distinct spatial pattern of human water use by sectors at the seasonal and annual

    This work deals with cogeneration and independent power production and, more specifically, with the feasibility and perspectives of these technologies in the Brazilian sugar-cane industry. In the first part of thesis, cogeneration and independent power production are assessed as decentralised power generation options. Some aspects of these technologies are identified, as the conditions in which they have developed in recent years, world-wide, and how they have been dealt with in the institutional structural changes under way in the public owned electric power sector in several countries. In the second part, the Brazilian sector and the sugar-cane industry are evaluated. The organisational structure of the electric power sector, the reasons of its institutional and financial crises and some structural changes proposals are discussed. In the other hand, the sugar-cane industry is studied according to the following aspects: its expansion in recent years, the concentration of the production, the alcohol production costs and why some degree of production diversification in this industrial branch is desirable. Several technological alternatives that allow a large scale electricity production in the sugar and alcohol sector are examined in the final part of this thesis. A simulation procedure was specially developed in this thesis and applied to a typical sugar and alcohol plant. With the help of this simulation procedure, technical and economic evaluations were carried out and the best alternatives are identified. Finally, their potential was calculated for the sugar-cane industry in the State of Sao Paulo, considering the possible expansion of the sugar and alcohol production and the mills that are amore appropriate to respond for this increase. The large scale electric power generation from sugar-cane by-products is an option that can bring about some advantages for the public owned electric power sector, as well for the sugar-cane one. As a matter of fact, looking

    Full Text Available The article focuses on the identification of innovation adoption and diffusion processes in the export horticultural sector in northwestern Mexico, and the differences identified taking into account the type of producer depending on the production size. The results of the adoption speed index suggests that large producers are distinguished as being early adopters and leaders in innovation adoption in this activity; but as long as there is a technological gap between small and large producers, that is increased even more by economical limita-tions, these will be identified as late adopters for this activity, supported by public programs for its adoption. The study was conducted in four entities of northwestern Mexico, Baja California, Baja California Sur, Sonora and Sinaloa, that in average contribute with 17 % of the national horticultural production. The international market is a strong promotor in innovation adoption, particularly in those related to food safety standards that are adopted by 84 % of the producers. The network analysis highlights the role of union organizations as technological innovation diffusors, e.g. the Confederation of Agricultural Associations of the Sinaloa State, and the Local Agricultural Association of horticulture, Fruits and Legumes of Hermosillo in Sonora.

    In the current economic conditions further increase of the profit or maintenance of its current level on the base of extensive development factors is no longer possible. The example of the oil-extracting company in the Republic of Tatarstan demonstrates that in the future it will be possible to replace traditional energy sources with solar energy; it will reduce energy costs for oil extraction, production costs and provide an increase of corporate efficiency. The economic analysis results show that the use of solar electricity can lead to 4.68% reduction in total electricity costs. In addition, the energy consumption per ton of oil produced is reduced. The share of electricity costs in the oil cost is reducing from 12.13% to 11.56%. Consequently, in the long term, the impact of total energy costs reduction can become more significant. In this way solar energy can become quite a real alternative in ensuring the energy needs of the economy of the oil-extracting sector of the Republic of Tatarstan and become a driver of intensive economic development.

    Full Text Available Over the past two decades, French enterprises have been heavily investing in the Czech Republic. Today, France is the fifth biggest investor to the Czech Republic, and French companies are among the most important employers. The aim of this study is to analyze the presence of French firms in Czech Republic by look at the example the French-Czech mergers and acquisitions (M&A, and to explain the main motivation of the location of French firms in the country. Using a review of documents and secondary data analysis, we observe that French enterprises have invested especially in the Czech manufacturing sector, energy & power, consumer staples and financial services. In this study, we evaluate if French corporations try to optimize their production process within so-called global value chains, and if French companies have invested in their own strategic domain area or another strategic area by using the diversification growth approach. Finally, we present examples of successful mergers and acquisitions of French firms realized in the Czech Republic.

    Many companies currently strive to support their employees' work-life balance through appropriate measures in order to improve employees' loyalty towards the company and to recruit new employees. In this context, flexibility in the area of working times is a measure that can influence employees' private lives immensely. This is why the individualisation of working time arrangements has been accorded high importance in current discussions on work-life balance. In this area, best practice examples can be found showing how working-time arrangements can improve the situation of the employees. It should be noted, however, that there is not one single perfect working-time model. A working-time model must always be adapted specifically to the actual situation of the company and the employees. Therefore, a targeted analysis of the challenges facing the company and the demands on the employees is essential for the creation of an appropriate working time policy. In particular, the employees' working-time preferences must be appropriately taken into account. Owing, however, to a combination of organisational complications and legal data protection restrictions, it is for the most part impossible to meet these working-time preferences in their entirety. This paper, which is based on an employee survey, illustrates the strain on employees in the retail sector and identifies different types of working-time preferences.

    Although solar costs are dropping rapidly, solar power is still more expensive than conventional and other renewable energy options. The solar sector still needs continuing government policy support. These policies are driven by objectives that go beyond the goal of achieving grid parity. The need to achieve multiple objectives and ensure sufficient political support for solar power makes it diffi cult for policy makers to design the optimal solar power policy. The dynamic and uncertain nature of the solar industry, combined with the constraints offered by broader economic, political and social conditions further complicates the task of policy making. This report presents an analysis of solar promotion policies in seven countries - Germany, Spain, the United States, Japan, China, Taiwan, and India - in terms of their outlook, objectives, policy mechanisms and outcomes. The report presents key insights, primarily in qualitative terms, and recommendations for two distinct audiences. The first audience consists of global policy makers who are exploring various mechanisms to increase the penetration of solar power in markets to mitigate climate change. The second audience consists of key Indian policy makers who are developing a long-term implementation plan under the Jawaharlal Nehru National Solar Mission and various state initiatives.

    Small and medium size enterprises (SMEs) have an important role in the Turkish economy because of the workforce involved. According to the size of the industrial facilities, there are different cost components related to the total production costs. Energy cost is usually a small portion of the total production cost, but the Turkish industrial sector comprises approximately 35% of Turkey's total energy consumption and 98.8% of the total number of enterprises in Turkey constitutes the SMEs. Because of the uncertainty of energy costs in the world, it is important to take preventive measures to reduce energy costs and increase efficiencies in industry and consequently in SMEs. In this paper, medium sized enterprises are taken into consideration essentially. Because of getting homogeneity, enterprises with the number of workers between 100 and 200 in the metallic goods industry have been considered in the survey. Energy management includes increasing the profitability by reduced operational costs, and it is also a potential for improving market share. Many different evaluation models have been published in the energy management literature. However, there have not been so many systematic approaches to compare the relative efficiency of the systems. Data envelopment analysis (DEA) is a special linear programming model for deriving the comparative efficiency of multiple-input multiple-output decision making units (DMUs). An evaluation of energy efficiency in 20 medium sized companies has been conducted, and the results are discussed in this paper

    2007-01-01

    Several factors are steering world energy supplies away from traditional fossil fuel sources and toward renewable energy technologies. As a result, renewable energy markets are experiencing significant growth, and experts predict this trend will continue. As of 2004, 2 per cent of Canada's total electricity generation capacity was provided from emerging renewable technologies, excluding large scale hydro which represents 56 per cent of Canada's electricity generation capacity. The development of renewable energy sources in Canada is expected to contribute to Canada's economic prosperity by providing diversified energy supply to industrial buyers, generating direct economic advantages and employment to local communities, as well as direct benefits such as improved air quality and lower greenhouse gas emissions. Human Resources and Social Development Canada contracted the Delphi Group to provide information on the labour market for the renewable energy sector in Canada in order to identify the steps needed to help the sector in developing a human resource strategy. This report provided an overview of key characteristics defining the renewable energy subsectors in Canada along with anticipated changes in the near term. The study focused on the following technologies: wind turbines; photovoltaics; active solar thermal; geoexchange/earth energy; small scale hydropower; bioenergy; and, ocean energy. A reliable estimate of the labour demands in the subsectors over the next 5 to 10 year was presented along with a review of the human resource issues affecting the sector. This project was guided by an advisory committee of members from 4 sector councils; 3 government agencies including Environment Canada, Industry Canada and Natural Resources Canada; 4 industry associations representing bioenergy, geothermal energy, solar energy and wind energy; and other organizations including the Association of Canadian Community Colleges, the Canadian Council of Technicians and

  11. Prices vs. quantities. Incentives for renewable power generation. Numerical analysis for the European power market

    Energy Technology Data Exchange (ETDEWEB)

    2013-02-15

    In recent years, many countries have implemented policies to incentivize renewable power generation. This paper outlines the effects of weather uncertainty on investment and operation decisions of electricity producers under a feed-in tariff and renewable quota obligation. Furthermore, this paper tries to quantify the sectoral welfare and investments risks under the different policies. For this purpose, a spatial stochastic equilibrium model is introduced for the European electricity market. The numerical analysis suggests that including the electricity market price in renewable policies (wholesale price + x) reduces the loss of sectoral welfare due to a renewable policy by 11-20 %. Moreover, investors face an only slightly higher risk than under fixed price compensations. However, electricity producers face a substantially larger investment risk when introducing a renewable quota obligation without the option of banking and borrowing of green certificates. Given the scenario results, an integration of the hourly market price in renewable support mechanisms is mandatory to keep the financial burden to electricity consumers at a minimum. Additionally, following the discussion of a European renewable quota after 2020, the analysis indicates the importance of an appropriate banking and borrowing mechanism in light of stochastic wind and solar generation.

    Full Text Available The importance of efficiency in resource utilization in healthcare sector has been recognized globally. In this paper we focus on efficiency of healthcare system at sub-state level (i.e., district level in India using Gujarat state and its district level data for 2012-13. In spite of being an economically advanced state, in terms of infant mortality rate (IMR the state is not the lowest. We explore the reasons for relative performance of different districts with data envelopment analysis (DEA. We used IMR as output variables. Using principal component analysis we tried a sub-set of variables, which had low correlations. Thus, four factor scores relating to medical officer, lady medical officer, Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy doctor, pharmacist, were used for DEA. We have focused on Charnes, Cooper, and Rhodes scores (or constant returns to scale technical efficiency score, and discussed efficiency rankings based on these. Thus, our results pertaining to district level health system efficiency in Gujarat State indicate that some of the districts have low efficiency in utilization of inputs like doctors, beds and workload per health institutions. There are also other districts, which need more of these inputs, which may enhance their output and efficiency. Thus, it is suggested that the efficiency in Valsad needs an improvement much more than other districts, whereas districts like Ahmadabad and Surat need more of both medical manpower and facilities. Even in case of Vadodara and Rajkot, the ranking in terms of most of medical manpower and facilities is low and thus these districts may also be benefitted by additional inputs. Hence, there is a mix of both inefficiency and inadequacy of inputs, which is reflected in our results.

    Aylin Yener

    2007-12-01

    Full Text Available We consider the joint optimization problem of cell sectorization, transmit power control and multiuser detection for a CDMA cell. Given the number of sectors and user locations, the cell is appropriately sectorized such that the total transmit power, as well as the receiver filters, is optimized. We formulate the corresponding joint optimization problems for both the uplink and the downlink and observe that in general, the resulting optimum transmit and receive beamwidth values for the directional antennas at the base station are different. We present the optimum solution under a general setting with arbitrary signature sets, multipath channels, realistic directional antenna responses and identify its complexity. We propose a low-complexity sectorization algorithm that performs near optimum and compare its performance with that of optimum solution. The results suggest that by intelligently combining adaptive cell sectorization, power control, and linear multiuser detection, we are able to increase the user capacity of the cell. Numerical results also indicate robustness of optimum sectorization against Gaussian channel estimation error.

    A bottom-up methodological framework was developed and applied for the period 1985-2002, to selected manufacturing sub-sectors in Greece namely, food, beverages and tobacco, iron and steel, non-ferrous metals, non-metallic minerals and paper. Disaggregate physical data were aggregated according to their specific energy consumption (SEC) values and physical energy efficiency indicators were estimated. The Logarithmic Mean Divisia index method was also used and the effects of the production, structure and energy efficiency to changes in sub-sectoral manufacturing energy use were further assessed. Primary physical energy efficiency improved by 28% for the iron and steel and by 9% for the non-metallic minerals industries, compared to the base year 1990. For the food, beverages and tobacco and the paper sub-sectors, primary efficiency deteriorated by 20% and by 15%, respectively; finally electricity efficiency deteriorated by 7% for the non-ferrous metals. Sub-sectoral energy use is mainly driven by production output and energy efficiency changes. Sensitivity analysis showed that alternative SEC values do not influence the results whereas the selected base year is more critical for this analysis. Significant efficiency improvements refer to 'heavy' industry; 'light' industry needs further attention by energy policy to modernize its production plants and improve its efficiency

    Operation and maintenance (O&M) of wind turbines is recently becoming the spotlight in the wind energy sector. While wind turbine power capacities continue to increase and new offshore developments are being installed, O&M costs keep raising. With the objective of reducing such costs, the new trends are moving from corrective and preventive maintenance toward predictive actions. In this scenario, condition monitoring (CM) has been identified as the key to achieve this goal. The induction generator of a wind turbine is a major contributor to failure rates and downtime where doubly-fed induction generators (DFIG) are the dominant technology employed in variable speed wind turbines. The current work presents the analysis of an in-service DFIG. A one-year measurement campaign has been used to perform the study. Several signal processing techniques have been applied and the optimal method for CM has been identified. A diagnosis has been reached, the DFIG under study shows potential gearbox damage.

    Moden, R.

    An analysis of expected energy savings between 1977 and 1980 under three different solar tax credit scenarios is presented. The results were obtained through the solar heating and cooling of buildings (SHACOB) commercialization model. This simulation provides projected savings of conventional fuels through the installation of solar heating and cooling systems on buildings in the residential and commercial sectors. The three scenarios analyzed considered the tax credits contained in the Windfall Profits Tax of April 1980, the National Tax Act of November 1978, and a case where no tax credit is in effect.

    Regulations require that electric power generation facilities monitor their liquid effluents. Acute lethality tests are simple, rapid standard methods for measuring potential impacts on aquatic ecosystems. These toxicity tests will detect harmful concentrations of chemicals and mixtures of compounds in effluents, but compliance with end of pipe limits for acute toxicity will not necessarily control all adverse environmental effects. In these tests, aquatic organisms were exposed to undiluted effluent, as well as a series of effluent dilutions for a fixed period of time. This report is a compilation of six months of test results. Typically the most toxic samples were taken from the waste treatment plant (WTP) neutral sumps. This was true for fossil fueled as well as for nuclear generating stations. tabs., figs

Las cooperativas agrarias, al igual que el resto de empresas, también están sometidas a cambios y por ello es necesario conocer sus puntos fuertes y débiles con la finalidad de detectar tanto oportunidades como amenazas. Hasta ahora el objetivo principal de las cooperativas ha estado el de la comercialización de los productos. Sin embargo, la nueva situación socioeconómica plantea la necesidad de que dichas entidades asuman nuevos objetivos, tales como la mejora de la calidad y la conservación del medio ambiente, nuevas estrategias de ventas, diversificación de la producción, etc. En el presente artículo se analizan las características generales del sector cooperativo en Cataluña para ver en que grado dicho sector tiene protagonismo en las fases posteriores a la producción.

    Full Text Available Current research and practice related to the first year experience (FYE of commencing higher education students are still mainly piecemeal rather than institution-wide with institutions struggling to achieve cross-institutional integration, coordination and coherence of FYE policy and practice. Drawing on a decade of FYE-related research including an ALTC Senior Fellowship and evidence at a large Australian metropolitan university, this paper explores how one institution has addressed that issue by tracing the evolution and maturation of strategies that ultimately conceptualize FYE as “everybody's business.” It is argued that, when first generation co-curricular and second generation curricular approaches are integrated and implemented through an intentionally designed curriculum by seamless partnerships of academic and professional staff in a whole-of-institution transformation, we have a third generation approach labelled here as transition pedagogy. It is suggested that transition pedagogy provides the optimal vehicle for dealing with the increasingly diverse commencing student cohorts by facilitating a sense of engagement, support and belonging. What is presented here is an example of transition pedagogy in action.

    Apps targeted at health and wellbeing sit in a rapidly growing industry associated with widespread optimism about their potential to deliver accessible and cost-effective healthcare. App developers might not be aware of all the regulatory requirements and best practice principles are emergent. Health apps are regulated in order to minimise their potential for harm due to, for example, loss of personal health privacy, financial costs, and health harms from delayed or unnecessary diagnosis, monitoring and treatment. We aimed to produce a comprehensive guide to assist app developers in producing health apps that are legally compliant and in keeping with high professional standards of user protection. We conducted a case study analysis of the Australian and related international policy environment for mental health apps to identify relevant sectors, policy actors, and policy solutions. We identified 29 policies produced by governments and non-government organisations that provide oversight of health apps. In consultation with stakeholders, we developed an interactive tool targeted at app developers, summarising key features of the policy environment and highlighting legislative, industry and professional standards around seven relevant domains: privacy, security, content, promotion and advertising, consumer finances, medical device efficacy and safety, and professional ethics. We annotated this developer guidance tool with information about: the relevance of each domain; existing legislative and non-legislative guidance; critiques of existing policy; recommendations for developers; and suggestions for other key stakeholders. We anticipate that mental health apps developed in accordance with this tool will be more likely to conform to regulatory requirements, protect consumer privacy, protect consumer finances, and deliver health benefit; and less likely to attract regulatory penalties, offend consumers and communities, mislead consumers, or deliver health harms.

  11. Cost analysis of various low pathogenic avian influenza surveillance systems in the Dutch egg layer sector.

    Directory of Open Access Journals (Sweden)

    Niels Rutten

    Full Text Available BACKGROUND: As low pathogenic avian influenza viruses can mutate into high pathogenic viruses the Dutch poultry sector implemented a surveillance system for low pathogenic avian influenza (LPAI based on blood samples. It has been suggested that egg yolk samples could be sampled instead of blood samples to survey egg layer farms. To support future decision making about AI surveillance economic criteria are important. Therefore a cost analysis is performed on systems that use either blood or eggs as sampled material. METHODOLOGY/PRINCIPAL FINDINGS: The effectiveness of surveillance using egg or blood samples was evaluated using scenario tree models. Then an economic model was developed that calculates the total costs for eight surveillance systems that have equal effectiveness. The model considers costs for sampling, sample preparation, sample transport, testing, communication of test results and for the confirmation test on false positive results. The surveillance systems varied in sampled material (eggs or blood, sampling location (farm or packing station and location of sample preparation (laboratory or packing station. It is shown that a hypothetical system in which eggs are sampled at the packing station and samples prepared in a laboratory had the lowest total costs (i.e. € 273,393 a year. Compared to this a hypothetical system in which eggs are sampled at the farm and samples prepared at a laboratory, and the currently implemented system in which blood is sampled at the farm and samples prepared at a laboratory have 6% and 39% higher costs respectively. CONCLUSIONS/SIGNIFICANCE: This study shows that surveillance for avian influenza on egg yolk samples can be done at lower costs than surveillance based on blood samples. The model can be used in future comparison of surveillance systems for different pathogens and hazards.

    2008-01-01

    Application of price mechanisms has been the important instrument for carbon reduction, among which the carbon tax has been frequently advocated as a cost-effective economic tool. However, blanket taxes applied to all industries in a country might not always be fair or successful. It should therefore be implemented together with other economic tools, such as emission trading, for CO 2 reduction. This study aims to analyze the impacts of combining a carbon tax and emission trading on different industry sectors. Results indicate that the 'grandfathering rule (RCE2000)' is the more feasible approach in allocating the emission permit to each industry sector. Results also find that the accumulated GDP loss of the petrochemical industry by the carbon tax during the period 2011-2020 is 5.7%. However, the accumulated value of GDP will drop by only 4.7% if carbon taxation is implemented together with emission trading. Besides, among petrochemical-related industry sectors, up-stream sectors earn profit from emission trading, while down-stream sectors have to purchase additional emission permits due to failure to achieve their emission targets

    In this paper, the useful concept of energy and exergy utilization is defined, analyzed and applied to the residential sector of Malaysia by taking into account the energy and exergy flows for a period of 8 years from the year 1997 to 2004. The energy and exergy efficiencies are determined for the devices used in this sector and found to be 70% and 28%, respectively. Energy and exergy flow diagrams for the overall efficiencies of Malaysian residential sector are also illustrated in this paper. It is found that the current methodology applied in Saudi Arabia is suitable to analyze energy and exergy use in Malaysian residential sector. It has been found that the exergy efficiency of the Malaysian residential sector appears to be much lower than its corresponding energy efficiency. It has been observed that about 21% of total exergy losses are caused by refrigerator-freezer and 12% of total loss is caused by air conditioner. Washing machine, fan and rice cooker contribute about 11%, 10% and 8% of total exergy losses, respectively

    2002-01-01

    The importance of nuclear energy as a vital and strategic resource in the U. S. and world's energy supply mix has led to an initiative, termed Generation IV by the U.S. Department of Energy (DOE), to develop and demonstrate new and improved reactor technologies. These new Generation IV reactor concepts are expected to be substantially improved over the current generation of reactors with respect to economics, safety, proliferation resistance and waste characteristics. Although a number of light water reactor concepts have been proposed as Generation IV candidates, the majority of proposed designs have fundamentally different characteristics than the current generation of commercial LWRs operating in the U.S. and other countries. This paper presents the results of a review of these new reactor technologies and defines the transient analyses required to support the evaluation and future development of the Generation IV concepts. The ultimate objective of this work is to identify and develop new capabilities needed by INEEL to support DOE's Generation IV initiative. In particular, the focus of this study is on needed extensions or enhancements to SCDAP/RELAP5/3D code. This code and the RELAP5-3D code from which it evolved are the primary analysis tools used by the INEEL and others for the analysis of design-basis and beyond-design-basis accidents in current generation light water reactors.

    In this research, as for light water reactors and fast breeder reactors, for the object of all the processes from the mining, transport and refining of fuel, electric power generation to the treatment and disposal of waste, the amount of energy input and the quantity of CO 2 emission over the life cycle were analyzed, and regarding the influence that the technical progress of nuclear power generation exerted to environment, the effect of improvement was elucidated. Attention has been paid to nuclear power generation as its CO 2 emission is least, and the effect of global warming is smallest. In order to reduce the quantity of radioactive waste generation in LWRs and the cost of fuel cycle, and to extend the operation cycle, the technical development for heightening fuel burnup is in progress. The process of investigation of the new technologies of nuclear power generation taken up in this research is described. The analysis of the energy balance of various power generation methods is discussed. In the case of pluthermal process, the improvement of energy balance ratio is dependent on uranium enrichment technology. Nuclear power generation requires much materials and energy for the construction, and emits CO 2 indirectly. The CO 2 unit emission based on the analysis of energy balance was determined for the new technologies of nuclear power generation, and the results are shown. (K.I.)

    This paper examines the impacts of wind power generation on the future choice of fuels and technologies in the power sector of Vietnam. The study covers a time frame of 20 yr from 2005 to 2025 and the MARKAL model has been chosen to be adaptable to this specific task. The results of the study show that on a simple cost base, power generated from wind is not yet competitive with that of fossil fuel-based power plants. In order to make wind energy competitive, either carbon tax or an emission reduction target on the system must be imposed. The presence of wind power could affect not only the change in generation mix from coal-based power plants to wind turbines but also an increase in the capacity of other technologies which emit less carbon dioxide. It thus helps reduce fossil fuel requirement and consequently enhances energy security for the country. The study also shows that wind turbine in Vietnam could be a potential CDM project for annex I party countries. (author)

  2. System dynamics analysis of strategies to reduce energy use in aluminum-intensive sectors

    2017-07-13

    Aluminum is one of the most widely used materials in industry, with applications in buildings, vehicles, aircraft, and consumer products. Its ubiquity is also on the rise: aluminum is beginning to supplant steel in lightweight vehicles and aircraft, and is used in many green or LEED-certified buildings. Although aluminum tends to be highly recycled, particularly by manufacturers of aluminum products, the sector as a whole is still far from a closed system. As a result, the increase in aluminum consumption also means an increase in primary aluminum production-an energy-intensive process-and an increase in consumption of the raw material bauxite, which in the U.S. is almost entirely imported. Our objectives for this study are to identify and analyze aluminum sector technologies and practices that reduce the energy required to manufacture aluminum products and reduce U.S. dependence on imported aluminum and bauxite. To accomplish these objectives, we will develop a system dynamics (SD) model of aluminum production, use and recycling in key application areas, including aerospace, ground vehicles and consumer products. The model will cover the entire aluminum supply chain as it exists in the U.S., from bauxite importing and refining, to the manufacture of products, to the product use phase and end-of-life processing steps. Aluminum flows throughout the model will be determined by the annual domestic demand for each application area as well as demand projections that extend to 2030. Energy consumption will be tracked based on the flows of aluminum through each step of the supply chain. Using the SD model, we will evaluate several technologies and practices that have the potential to reduce energy consumption and reliance on imported bauxite. These include implementation of advanced primary aluminum production technologies, increased recycling within and between application areas, increased material efficiency and increased product lifetimes. Each of these strategies

    Neutron sources are increasingly employed in a wide range of research fields. For some specific purposes an alternative to existing large-scale neutron scattering facilities, can be offered by the new generation of portable neutron devices. This review reports an overview for such recently available neutron generators mainly addressed to biophysics applications with specific reference to portable non-stationary neutron generators applied in Neutron Activation Analysis (NAA). The review reports a description of a typical portable neutron generator set-up addressed to biophysics applications. New generation portable neutron devices, for some specific applications, can constitute an alternative to existing large-scale neutron scattering facilities. Deuterium-Deuterium pulsed neutron sources able to generate 2.5MeV neutrons, with a neutron yield of 1.0×10 6 n/s, a pulse rate of 250Hz to 20kHz and a duty factor varying from 5% to 100%, when combined with solid-state photon detectors, show that this kind of compact devices allow rapid and user-friendly elemental analysis.

    Partridge, Ian

    2013-01-01

    The cost of electricity generation using renewable technologies is widely assumed to be higher than the cost for conventional generation technologies, but likely to fall with growing experience of the technologies concerned. This paper tests the second part of that statement using learning rate analysis, based on large samples of wind and small hydro projects in India, and projects likely changes in these costs through 2020. It is the first study of learning rates for renewable generation technologies in India, and only the second in any developing country—it provides valuable input to the development of Indian energy policy and will be relevant to policy makers in other developing countries. The paper considers some potential problems with learning rate analysis raised by Nordhaus (2009. The Perils of the Learning Model for Modeling Endogenous Technological Change. National Bureau of Economic Research Working Paper Series No. 14638). By taking account of these issues, it is possible both to improve the models used for making cost projections and to examine the potential impact of remaining forecasting problems. - Highlights: • The first learning rate analysis of wind generation costs in India. • Only the second learning rate analysis for wind in any developing country. • Reviews missing variable and related issues in learning rate analysis. • Finds a 17.7% learning rate for wind generation costs in India. • Finds no significant learning effect for small hydro

    2013-06-01

    Full Text Available This paper presents a co-generation system based on combined heat and power for commercial units. For installation of a co-generation system, certain estimates for this site should be performed through making assessments of electrical loads, domestic water, and thermal demand. This includes domestic hot water, selection of the type of power generator, fuel cell, and the type of air conditioning system, and absorption chillers. As a matter of fact, the co-generation system has demonstrated good results for both major aspects, economic and environmental. From the environmental point of view, this can be considered as an ideal solution for problems concerned with the usage of Chlorofluoro carbons. On the other hand, from the economic point of view, the cost analysis has revealed that the proposed system saves 4% of total cost through using the co-generation system.

  11. The Need for a Higher Fuel Efficiency of the Electricity Sector - An Analysis of Opportunities and Barriers

    Energy Technology Data Exchange (ETDEWEB)

    Klimstra, J.

    2007-07-01

    The electricity sector is the single largest user of primary energy in the world. The issues of fuel prices, security of supply and greenhouse gas emissions are therefore closely connected with electricity generation. The total energy efficiency of the electricity sector is only 32.5% so that quick improvements are required. However, the uncertainty over fuel prices and technology preferences is such that most investors are hesitant. The life of existing, often low-efficiency, power plants is therefore extended. At the same time, the demand for electricity is rapidly increasing and the gap between capacity and demand decreases. This paper intends to bring more clarity into the economic and environmental boundary conditions of power plants. The goal is to find an attractive way for rapid efficiency improvement with an even better system reliability without increasing the costs. The paper discusses fuel price developments and the costs of generating technologies in connection with the typical demand pattern of electricity. Ultimately, it appears that local generation, preferably coupled with cogeneration, can be an important part of the solution. (auth)

  12. Renewable energy and greenhouse gas emissions from the waste sectors of European Union member states: a panel data analysis.

    In the last two decades, there has been a rich debate about the environmental degradation that results from exposure to solid urban waste. Growing public concern with environmental issues has led to the implementation of various strategic plans for waste management in several developed countries, especially in the European Union. In this paper, the relationships were assessed between economic growth, renewable energy extraction and greenhouse gas (GHG) emissions in the waste sector. The Environmental Kuznets Curve hypothesis was analysed for the member states of the European Union, in the presence of electricity generation, landfill and GHG emissions for the period 1995 to 2012. The results revealed that there is no inverted-U-shaped relationship between income and GHG emissions in European Union countries. The renewable fuel extracted from waste contributes to a reduction in GHG, and although the electricity produced also increases emissions somewhat, they would be far greater if the waste-based generation of renewable energy did not take place. The waste sector needs to strengthen its political, economic, institutional and social communication instruments to meet its aims for mitigating the levels of pollutants generated by European economies. To achieve the objectives of the Horizon 2020 programme, currently in force in the countries of the European Union, it will be necessary to increase the share of renewable energy in the energy mix.

  14. Economic analysis of the water demand in the hotels and restaurants sector: Shadow prices and elasticities

    Despite the growing economic importance of tourism, and its impact on relative water shortage, little is known about the role that water plays in the productive process of hotels and restaurants and, therefore, the possible implications of water demand management policy for this sector. This study aims to fill this gap. It is based on the microdata of 676 firms in the sector, operating in the city of Zaragoza (Spain) for a 12 year period. Based on the Translog cost function, we estimate the shadow price of water in the short run and, from a long-run perspective, its direct price elasticity, its cross elasticities relative to labor, capital, and supplies, and its elasticity with respect to the level of output. The results obtained show that water provides sector firms returns that are on average higher than its price, although in the case of hotels the margin is really narrow. This situation provides policy makers with a margin for applying price increases without affecting the sector's viability, with some caution in the case of hotels. Water demand elasticity equals -0.38 in the case of hotels, but it is not significant in the case of restaurants and bar-cafes; hence, only in hotels is there potential for influencing water use patterns, encouraging the resource's conservation through pricing policy. Moreover, capital is a substitutive factor of water, and the elasticity of water with respect to output is 0.40, all of which should also be considered by policy makers in water resource management.

    2017-06-01

    Full Text Available Sectoral linkages of financial services of the Nigerian and Kenyan economies are evaluated by means of an input–output analysis for 2007, 2009 and 2011. Backward linkages, forward linkages, multiplier effects and variation indices for the financial services sectors are determined. Due to the increasing importance of mobile money, we additionally investigate these linkages for the communication sector. We find high forward and backward linkages for the Nigerian financial services sector only. Here, changes in final demand for or primary input into the financial sector have a wide and evenly spread impact on the rest of the economy classifying the financial sector as a key sector. Regarding Kenya, however, the sectoral linkages of the financial services sector are lower. This may be due to the well-developed mobile financial market in Kenya. But results for the communication sector, however, yield rather low linkage values and multiplier effects for both economies. All results are confirmed by a robustness test. Nonetheless, they could have been influenced by a lack of data coverage especially with regard to mobile money and a high degree of informal financial transactions. Still, our findings confirm the significance of financial services as channels of economic development for both the economies.

    Kirjavainen, M.; Tamminen, E.

    2002-03-01

    This study describes the development of energy consumption and energy related CO 2 emissions in Finland between 1990-1999. For better understanding of the factors behind the development in main sectors, special indicators are calculated to evaluate how the overall development of the sector is affected by the general activity of the sector, changes in sectoral structure and changes in end-use intensities within the sector. The specific energy consumption of space heating reduced especially during the first half of the decade. Also the total CO 2 emissions caused by space heating reduced, in spite of the increase in the building stock. The main reason for this has been the reduction in specific CO 2 emissions in production of district heat. Regardless of the increased traffic and slightly increased use of passenger cars over public transport, the total energy consumption as well as total CO 2 emissions in passenger transport reduced during the decade. The main reason for this is that the specific fuel consumption of passenger cars has reduced significantly. Volumes in freight traffic increased rapidly after the recession, and as no significant changes have occurred in either specific consumptions or in shares of different transport modes, the total energy use as well as total CO 2 emissions of freight transport have increased. The major factors affecting the energy use and CO 2 emissions of the manufacturing sector have been changes in production volumes. After the recession, growth has been rapid and that has resulted in increased total energy use and CO 2 emissions. Anyway, the especially rapid growth of the less energy intensive electronics industry has resulted in downward overall energy intensity within manufacturing sector. Major factors affecting the specific CO 2 emissions in energy production have been changes in the primary energy supply mix. In electricity production, the major factors have been the increase in nuclear capacity and the variation in net

    Northern China has been facing severe water scarcity as a result of vigorous economic growth, population expansion and changing lifestyles. A typical case is Shandong province whose water resources per capita is approximately only a sixth of the national average and a twentieth of the global average. It is useful to assess the implications of the province’s growth and trade patterns for water use and water conservation strategies. This study quantitatively analyses relationships between regional economic sectors and water use in Shandong using an input-output model for virtual water resources. The changes in key indicators for 1997-2007 are tracked and the effects of water-saving policies on these changes are examined. The results highlight the benefits of applying a virtual water trade analysis on a water-scarce region where water resources exhibit highly heterogeneous temporal and geographical distributions. The net export of virtual water in Shandong was initially large, but this declined over the years and the province has recently become a net importer. Between 1997 and 2002, water use in most sectors increased due to rapid urbanisation and industrialisation. Since then, water use in all Shandong economic sectors exhibit a downward trend despite continued increases in goods and services net exports, a trend which can be attributed to the vigorous implementation of water-saving policies and measures, especially water use quotas. Economic sectors consume water directly and indirectly and understanding the pattern of virtual water trade implied by sectoral relationships is important for managing water scarcity problems. This study fills the knowledge gap in the existing literature created by the lack of case studies that dynamically assess virtual water trade and analyse the effects of water-saving policies and measures. The study draws policy recommendations that are relevant for future water planning in Shandong and other regions in northern China.

    Highlights: ► We evaluate energy efficiency under framework of total factor energy efficiency. ► We focus on industry sector of China. ► We use statistical data of industrial enterprises above designated size. ► Energy efficiencies among regions in China are obvious because of technological differences. ► Large scale of investment should be stopped especially in central and western regions. -- Abstract: The rapid growth of the Chinese economy has resulted in great pressure on energy consumption, especially the energy intensive sector – the industrial sector. To achieve sustainable development, China has to consider how to promote energy efficiency to meet the demand of Chinese rapid economic growth, as the energy efficiency of China is relatively low. Meanwhile, the appeal of energy saving and emission reduction has been made by the Chinese central government. Therefore, it is important to evaluate the energy efficiency of industrial sector in China and to assess efficiency development probabilities. The framework of total factor energy efficiency index is adopted to determine the discrepancy of energy efficiency in Chinese industrial sector based on the provincial statistical data of industrial enterprises above designated size in 30 provinces from 2005 to 2009, with gross industrial output as the output value and energy consumption, average remaining balance of capital assets and average amount of working force as the input values. Besides, in considerate of the regional divide of China, namely eastern, central, and western, and economic development differences in each region, energy efficiency of each region is also analysed in this paper. The results show that there is room for China to improve its energy efficiency, especially western provinces which have large amount of energy input excess. Generally speaking, insufficient technological investment and fail of reaching best scale of manufacture are two factors preventing China from energy

    2013-01-01

    The National Energy Modeling System (NEMS) is arguably the most influential energy model in the United States. The U.S. Energy Information Administration uses NEMS to generate the federal government's annual long-term forecast of national energy consumption and to evaluate prospective federal energy policies. NEMS is considered such a standard tool that other models are calibrated to its forecasts, in both government and academic practice. As a result, NEMS has a significant influence over expert opinions of plausible energy futures. NEMS is a massively detailed model whose inner workings, despite its prominence, receive relatively scant critical attention. This paper analyzes how NEMS projects energy demand in the residential and commercial sectors. In particular, we focus on the role of consumers' preferences and financial constraints, investigating how consumers choose appliances and other end-use technologies. We identify conceptual issues in the approach the model takes to the same question across both sectors. Running the model with a range of consumer preferences, we estimate the extent to which this issue impacts projected consumption relative to the baseline model forecast for final energy demand in the year 2035. In the residential sector, the impact ranges from a decrease of 0.73 quads (− 6.0%) to an increase of 0.24 quads (+ 2.0%). In the commercial sector, the impact ranges from a decrease of 1.0 quads (− 9.0%) to an increase of 0.99 quads (+ 9.0%). - Highlights: • This paper examines the impact of consumer preferences on final energy in the Commercial and Residential sectors of the National Energy Modeling System (NEMS). • We describe the conceptual and empirical basis for modeling consumer technology choice in NEMS. • We offer a range of alternative parameters to show the energy demand sensitivity to technology choice. • We show there are significant potential savings available in both building sectors. • Because the model uses its own

Para cada uno de estos sectores, seguimos el mismo procedimiento. En primer lugar, aplicamos un análisis de componentes principales con el que identificamos los factores explicativos del fracaso empresarial en los tres sectores. A continuación, consideramos dichos factores como variables independientes en un análisis discriminante, que aplicamos para predecir el fracaso de una muestra de empresas, utilizando no sólo información financiera en forma de ratios, sino también otras variables no financieras relativas a las empresas, así como información externa a las mismas que refleja las condiciones macroeconómicas bajo las que desarrollan su actividad. This paper focuses on a cross-industry analysis of business failure, in order to identify the explanatory and predictor factors of this event that are different in three of the main industries in every economy: manufacturing, building and service. For each one of these industries, the same procedure is followed. First, a principal components analysis is applied in order to identify the explanatory factors of business failure in the three industries. Next, these factors are considered as independent variables in a discriminant analysis, so as to predict the firms’ failure, using not only financial information expressed by ratios, but also other non-financial variables related to the firms, as well as external information that reflects macroeconomic conditions under which they develop their activity.

    Full Text Available Human water withdrawal has increasingly altered the global water cycle in past decades, yet our understanding of its driving forces and patterns is limited. Reported historical estimates of sectoral water withdrawals are often sparse and incomplete, mainly restricted to water withdrawal estimates available at annual and country scales, due to a lack of observations at seasonal and local scales. In this study, through collecting and consolidating various sources of reported data and developing spatial and temporal statistical downscaling algorithms, we reconstruct a global monthly gridded (0.5° sectoral water withdrawal dataset for the period 1971–2010, which distinguishes six water use sectors, i.e., irrigation, domestic, electricity generation (cooling of thermal power plants, livestock, mining, and manufacturing. Based on the reconstructed dataset, the spatial and temporal patterns of historical water withdrawal are analyzed. Results show that total global water withdrawal has increased significantly during 1971–2010, mainly driven by the increase in irrigation water withdrawal. Regions with high water withdrawal are those densely populated or with large irrigated cropland production, e.g., the United States (US, eastern China, India, and Europe. Seasonally, irrigation water withdrawal in summer for the major crops contributes a large percentage of total annual irrigation water withdrawal in mid- and high-latitude regions, and the dominant season of irrigation water withdrawal is also different across regions. Domestic water withdrawal is mostly characterized by a summer peak, while water withdrawal for electricity generation has a winter peak in high-latitude regions and a summer peak in low-latitude regions. Despite the overall increasing trend, irrigation in the western US and domestic water withdrawal in western Europe exhibit a decreasing trend. Our results highlight the distinct spatial pattern of human water use by sectors at

    Full Text Available La industria textil ha sido un pilar fundamental en el desarrollo de la economía global al generar un comercio sin fronteras. Hoy en día, las empresas de este sector basan sus éxitos o fracasos en tres variables fundamentales como lo son (1 el costo, (2 la calidad y (3 el tiempo de entrega de sus productos. No ha de sorprender que si sus resultados no son positivos, exista presión en la reducción de gastos, lo que influye en la toma de decisiones para cierres de plantas o traslados a otras regiones donde haya un costo competitivo. No obstante, más allá de los análisis financieros, la calidad del producto y el nivel de entregas, la pregunta clave sería: ¿estas empresas han creado o destruido riqueza? Por consiguiente, el énfasis de este estudio se centra en el desarrollo y análisis de un modelo que permita determinar si las empresas de este sector han creado o destruido riqueza en los diferentes periodos, puesto que ellas no cuentan con una herramienta que les brinde dicha información y les ayude en la toma de decisiones. Como resultado del modelo planteado se llega a la conclusión de que ninguna de ellas mantiene una tendencia marcada y que los diferentes métodos no son afines entre sí en los mismos periodos; sin embargo, se orienta mejor la toma decisiones mediante la interpretación de los resultados, en lugar de depender exclusivamente de los registros financieros.   ABSTRACT Textile industries are fundamental in the development of a barrier-free global economy. Nowadays, these companies can pin their success or failure to three fundamental variables: (1 cost, (2 quality, and (3 product delivery time. It is not rare that if year end results aren´t positive, there is pressure to reduce expenses and influence decision making regarding plant closures, or outsourcing from areas where there still are competitive costs.

    In order to prevent the expansion of tube damages and to maintain structural safety in steam generators (SG) of fast breeder reactors (FBR), it is necessary to detect precisely and immediately the leakage of water from tubes of heat exchangers. Therefore, an active acoustic method, which detects the sound attenuation due to bubbles generated in the sodium-water reactions, it being developed. In this paper, the attenuation characteristics of sound attenuated by bubbles and influence of background noise are investigated experimentally by using an SG full sector model (diameter ratio about 1/1, height ratio about 1/7) simulating the actual SG. As an experimental result, the received sound attenuation for ten seconds was more than 10 dB from air bubble injection when injected bubble of 10 l/s (equivalence water leak rate about 10 g/s). The attenuation of sound are least affected by bubble injection position of heat exchanger tube bunch department. And the time was about 25 seconds till the sound attenuation became 10 dB in case of quantity of air bubble 1 l/s (equivalent water leak rate about 1 g/s). It is clarified that the background noise hardly influenced water leak detection performance as a result of having examined influence of background noise. (author)

    Occupational Health Doctors active in building sector firms frequently have to evaluate residual workers' osteomuscular function in patients coming back to work after an accident happened during work time or free time. Definition of their specific individual work suitability is usually carried out utilizing semeiotic tests in which subjective evaluation of every single Medical Doctor is real important in definition of final results and this fact can cause legal controversies. In our research we describe the application of computerised movement analysis on 10 workers of building sector. In every patient examined this technical method has been able to study objectively the tridimensional ranges of motion of most important osteomuscular districts. The possibility to have an objective evaluation of residual osteomuscular function has a relevant importance both in definition of workers' work suitability at the moment in which they start again their activities and in possible future legal conflicts.

    The railway system represents one of the most resource-efficient answer to our ever-growing demand for transport service and the development trends for the following years forecast a substantial increase in this sector. Considering the European Union, rolling stock realizes a significant share of both goods and passengers carriage while it is responsible for a derisory quota of environmental impact and energy consumption involved by transportation. Contrary to the low environmental impact, the amount of End-of-Life (EoL) waste generated by rolling stocks in relation to the number of vehicles is notable, much greater than in the case of road vehicles. As railway vehicles are constituted by many heterogeneous components, the EoL rolling stock is a precious source of materials, whose recycling brings measurable economic benefits and needs to be appropriately debated. The paper presents calculation of recoverability/recyclability rate for different typologies of vehicles representative of railway transport; calculation is performed on the basis of primary data and according to the recyclability and recoverability calculation method issued by UNIFE in the context of Product Category Rules (PCR). The typologies of railway vehicles taken into account are electric metro, diesel commuter train and high-speed electric train. The analysis envisages also to replicate the calculation in case innovative materials and manufacturing technologies are adopted in the construction of car-body structure. Results show that recyclability/recoverability rates are abundantly over the quota of 90% for each one of the three trains, these latter being made in major part of metals that benefit from very efficient recovery processes. The adoption of innovative materials and manufacturing technologies for car-body structure involves a scarce reduction of recyclability and recoverability rates (about 2% and 0.2% respectively) due to the introduction of components and materials characterized by

    2006-01-01

    Full Text Available The article presents a proposal of a methodology aimed to analyze the health care sector according to the dynamics of capital accumulation. That approach could be summed up to more traditional approaches founded in the Public Health field, based in a political perspective. The proposal departs from concepts and methods of Industrial Organization, already used for health care markets, in the European and Latin-American (CEPAL contexts. We aggregated economic and historical variables to these approaches, which delimitate possibilities and impose constraints to the strategies of the local agents. The objective of the paper is to give methodological support to public managers at state and local level, whose role as the single commander in their territories is prescribed by the present health policy in Brazil. That includes all the fields related to private sector regulation in health: from planning the supply to quality control of providers.

    Following a strategic orientation towards sustainable development, the Government of the Republic of Croatia has changed its energy legislation and has put forward a framework for the systematic development and increased use of renewable energy sources and cogeneration. This paper focuses on changes in the regulatory context relevant to the cogeneration sector and also analyses the impact of energy market transition on cogeneration viability in municipal district heating, industry, services and the residential sector. Particular attention has been paid to the expected changes of heat, electricity and gas prices. We present a simple model for quantitative prediction of the cogeneration system profitability at different power levels under given national circumstances. Our findings support a need for a strong institutional support for initial penetration of the micro-cogeneration technologies into the Croatian energy system. (author)

    Hydroelectric power or Hydropower means the power generated by the help of flowing water with force. It is one the best source of renewable energy in the world. Water evaporates from the earth's surface, forms clouds, precipitates back to earth, and flows toward the ocean. Hydropower is considered a renewable energy resource because it uses the earth's water cycle to generate electricity. As far as Global is concerned, only a small fraction of electricity is generated by hydro-power. The aim of our analysis is to demonstrate and observe the hydropower of the Globe in micro-scale by our experimental setup which is completely new in concept. This paper consists of all the Global and National Scenario of Hydropower. And how we can more emphasize the generation of Hydroelectric power worldwide.

    2009-01-01

    Recent measures to restructure the electric power sector in different US states have raised the interest of policy makers, commentators, and the general public as to the actual impact of restructuring on both the economy and the environment. This paper focuses on two aspects of restructuring, namely its potential impact on the efficiency of electricity generation and air pollution. Our empirical results suggest that restructuring contributes to improved efficiency of electricity generation and better air quality through reduced electricity-induced sulfur dioxide (SO 2 ) and carbon dioxide (CO 2 ) emissions, although no effect was found for emissions of nitrous oxides (NO x ). These results, in turn could have important implications for policy in this area. (author)

    Producing electricity at an affordable price while taking into account environmental concerns has become a major challenge in Morocco. Moreover, the technical and financial issues related to renewable electricity plants are still hindering their efficient integration in the country. In fact, the energy sector (both electricity and heat) accounted for more than half of all Greenhouse Gases (GHG) emissions in the kingdom due to the major reliance on fossil fuels for answering the growing local demand. The key strategies to alleviate this critical situation include the integration of more renewable energies in the total energy mix and the enhancement of energy efficiency measures in different sectors. This paper strives to (1) evaluate the potential of carbon dioxide mitigation in Moroccan electricity sector following the actual and projected strategies and (2) highlight the policy schemes to be taken in order to achieve the ambitious carbon dioxide mitigation targets in the mid-term. A system dynamics model was built in order to simulate different scenarios of carbon dioxide mitigation policies up to 2030. The results shows that the achievement of renewable energies projects by 2030 could save 228.143 MtCO2 between 2020 and 2030 and an additional 18.127 MtCO2 could be avoided in the same period by enhancing energy efficiency measures.

    Full Text Available This paper examines whether Nigeria witnessed considerable savings mobilization amidst financial sector reforms from 2007 to 2015 using the estimation method of Autoregressive Distributed Lag. Unlike previous papers in this area that mostly focused on interest rates liberalization thesis, this paper goes deeper by looking at financial reforms across money, capital and foreign exchange markets. The estimation results show that there are still structural rigidities in the money, foreign exchange and equity markets nexus. In that, the following variables that proxy financial sector reforms namely treasury bill yield, interest rate spread, market capitalization ratio and currency in circulation ratio (which proxy technological modernization of payment systems all went against a priori expectation. However, financial reforms had one success story in credit/loans advances to private/public sectors (financial deepening which posted its correct economic sign. In sum, except for the financial deepening variable it can be safely concluded that financial reforms in Nigeria is yet to positively impact savings mobilization. The regulatory and reform authorities must show effectiveness in reforms implementation.

    Sebri, Maamar; Abid, Mehdi

    2012-01-01

    Following the importance of energy in the agrarian economies, the investigation of the causal relationship between energy consumption in agriculture sector and economic growth has a fundamental role in implementing suitable policies. This paper examines the causal relationship between energy consumption and agricultural value added, controlling for trade openness, in Tunisia from 1980 to 2007. The relationship is investigated at aggregated as well as disaggregated components of energy consumption, including oil and electricity. Using Granger's technique, it is shown that various results are obtained regarding the direction of causality between competing variables. Nevertheless, the most common finding suggest that trade openness and both aggregated and disaggregated energy consumption Granger causes agricultural value added. Therefore, the energy-led growth and trade-led growth hypotheses are supported in the Tunisian agriculture sector. An important policy implication resulting from this study is that energy can be considered as a limiting factor to agriculture value added and, therefore, shocks to energy supply would have a negative impact onto agriculture performance. Furthermore, trade liberalization seems to be a stimulus factor to the Tunisian agriculture development. - Highlights: ► We study the energy consumption-economic growth nexus of Tunisian agriculture sector. ► We use Johansen's cointegration approach and Granger causality. ► Energy consumption can be considered as limiting factor to agricultural performance. ► Electrical energy will represent an important input to agricultural production growth.

    The Fossil2 energy-economic model is used by the US Department of Energy (DOE) for a variety of energy and environmental policy analyses. A number of improvements to the model are under way or are being considered. This report was prepared by the Pacific Northwest Laboratory (PNL) to provide a clearer understanding of the current industrial sector module of Fossil2 and to explore strategies for improving it. The report includes a detailed description of the structure and decision logic of the industrial sector module, along with results from several simulation exercises to demonstrate the behavior of the module in different policy scenarios and under different values of key model parameters. The cases were run with the Fossil2 model at PNL using the National Energy Strategy Actions Case of 1991 as the point of departure. The report also includes a discussion of suggested industrial sector module improvements. These improvements include changes in the way the current model is used; on- and off-line adjustments to some of the model's parameters; and significant changes to include more detail on the industrial processes, technologies, and regions of the country being modeled. The potential benefits and costs of these changes are also discussed
