    Wetlands are producing several valuable resources like fish, potential for recreation, water cleaning etc. These resources, and methods for assigning an economic value to them, are discussed in this article. Swedish and foreign empirical studies of the economic value of wetlands are reviewed. This review shows that socioeconomic estimates of the value of wetlands risk to be misleading if the direct and indirect values are not properly accounted for. 37 refs

    2015-08-01

    To explore the experience of older adults in their neighborhood in relation to perceived fall risk, fear of falling (FOF), and resources/strategies for fall prevention. Fourteen older adults, 65 years of age and older from 3 urban senior centers, participated in this qualitative study. The semistructured interview guidelines and background questionnaire were developed by the researchers based on the literature and an existing measure of walkability. Both tools were refined based on pilot interviews with seniors. Collaizzi's phenomenological method was used for data analysis. Five themes emerged from the data: (a) The built environment contributes to perceived fall risk and FOF, (b) personal strategies used to adapt to perceived neighborhood fall risks-behavioral approaches, (c) resources for physical activity and safety, (d) barriers to physical activity and exercise, and (e) neighborhood features as a motivator. Urban-dwelling seniors perceive that neighborhood features contribute to or mitigate fall risk and FOF. Behavioral strategies are used by seniors to prevent outdoor falls. The findings can help clinicians develop targeted fall prevention interventions for well elders and help urban planners to design and retrofit urban environments to reduce fall risk. © The Author 2014.

  6. Economic Values and Resource Use

    Directory of Open Access Journals (Sweden)

    Jan Mikael Malmaeus

    2016-05-01

    Full Text Available Absolute decoupling of GDP growth from resource use implies that economic output can be increased without simultaneously increasing input. The essential meaning of this proposition is that the economic values that represent the GDP can be realized by increasing resource efficiency. Given that the GDP is first and foremost a measure of economic activity rather than welfare the possibility of absolute decoupling is theoretically limited. This paper demonstrates theoretically and empirically that economic values at the macroeconomic level are fundamentally determined by the use of production factors, primarily labor and physical capital. Technical innovations or efficiency gains increasing utility without raising the costs of production do not add to the GDP unless they stimulate investments in physical capital. Hence the neoclassical notion of productivity is only found to be relevant as a microeconomic concept. In practice, GDP growth is mostly explained by capital accumulation and a key question is whether or not capital accumulation can be decoupled from the use of materials and energy. This will determine the possibility of decoupling of GDP growth from resource use and environmental impact. Alternative measures of progress focusing on welfare rather than economic activity are more likely to achieve absolute decoupling.

  7. Exploration can cause falling non-renewable resource prices

    International Nuclear Information System (INIS)

    Boyce, John R.

    2003-01-01

    This note shows that when marginal exploration costs are increasing in the rate of exploration that it is possible to observe non-renewable resource prices falling over a portion of the extraction profile. Thus, while the model of Pindyck (J. Polit. Econ. 86 (1978) 841) was based on an incorrect specification of the aggregate extraction cost function, its general conclusion that exploration can cause falling non-renewable resource prices is upheld. This result is in contrast to Mendelsohn and Swierzbinski (Int. Econ. Rev. 30 (1989) 175), who assumed that marginal extraction costs were constant

    2005-03-01

    This thesis constitutes a study on renewable resource economics. Chapter 2 presents two types of extracting behaviour in two optimal control models, continuous and impulse control. Chapter 3 analyses stock dependent instruments and shows their advantages. Chapter 4 compares the two types of extracting behaviour and demonstrates that the impulse control generates higher gains, whereas fiscal revenues and stocks are not always higher. Chapter 5 establishes a dynamic game and shows that the scope for cooperation between heterogeneous agents is greatest for intermediary levels of heterogeneity. Chapter 6 studies forest exploitation and fiscal- and regulatory systems of the forest sector in the Democratic Republic of Congo and in France. Finally, chapter 7 presents a study on forest biodiversity and indicates the economic criteria and cutting strategies that are beneficial for biodiversity preservation. (author)

    2003-02-28

    In 2000, NETL conducted a review of the adequacy of the resource characterization databases used in its Gas Systems Analysis Model (GSAM). This review indicated that the most striking deficiency in GSAM’s databases was the poor representation of the vast resource believed to exist in low-permeability sandstone accumulations in western U.S. basins. The model’s databases, which are built primarily around the United States Geological Survey (USGS) 1995 National Assessment (for undiscovered resources), reflected an estimate of the original-gas-inplace (OGIP) only in accumulations designated “technically-recoverable” by the USGS –roughly 3% to 4% of the total estimated OGIP of the region. As these vast remaining resources are a prime target of NETL programs, NETL immediately launched an effort to upgrade its resource characterizations. Upon review of existing data, NETL concluded that no existing data were appropriate sources for its modeling needs, and a decision was made to conduct new, detailed log-based, gas-in-place assessments.

    Full Text Available The article reviews international debates on development problems of the resource-based economies. It draws atten tion to causes and mechanisms of the so-called "resource curse" and symptoms of systemic breakdowns and stagnant phenomena in resource-based economies named "Dutch disease". Specific attention is given to the role of national elites and institutions in the emergence of "Dutch disease", preservation of economic backwardness and/or de-industrialization of resource-rich countries. The author also considers new approaches to resolving the problem of'resource-curse", in particular, return to traditional instruments of economic diversification as industrialization and protectionism.

  11. Renewable Resources, Capital Accumulation, and Economic Growth

    Directory of Open Access Journals (Sweden)

    Wei-Bin Zhang

    2011-01-01

    Full Text Available This paper proposes a dynamic economic model with physical capital and renewable resources. Different from most of the neoclassical growth models with renewable resources which are based on microeconomic foundation and neglect physical capital accumulation, this study proposes a growth model with dynamics of renewable resources and physical capital accumulation. The model is a synthesis of the neoclassical growth theory and the traditional dynamic models of renewable resources with an alternative approach to household behavior. The model describes a dynamic interdependence among physical accumulation, resource change, and division of labor under perfect competition. Because of its refined economic structure, our study enables some interactions among economic variables which are not found in the existing literature on economic growth with renewable resources. We simulate the model to demonstrate the existence of equilibrium points and motion of the dynamic system. Our comparative dynamic analysis shows, for instance, that a rise in the propensity to consume the renewable resource increases the interest rate and reduces the national and production sector’s capital stocks, wage rate and level of the consumption good. Moreover, it initially reduces and then increases the capital stocks of the resource sector and the consumption and price of the renewable resource. The stock of the renewable resource is initially increased and then reduced. Finally, labor is redistributed from the production to the resource sector.

With the rising relevance of water economics and related social sciences, the editors of WRR continue to encourage submissions on economics and policy. WRR was originally founded in the mid 1960s by Walter Langbein and economist Allen Kneese. Several former WRR editors have been economists—including David Brookshire, Ron Cummings, and Chuck Howe—and many landmark articles in water economics have been published in WRR.

  16. National Uranium Resource Evaluation: Wichita Falls Quadrangle, Texas and Oklahoma

    International Nuclear Information System (INIS)

    Edwards, M.B.; Andersen, R.L.

    1982-08-01

    The uranium favorability of the Wichita Falls Quadrangle, Texas and Oklahoma, was determined by using National Uranium Resource Evaluation criteria; by subsurface studies of structure, facies distribution, and gamma-ray anomalies in well logs to a depth of 1500 m; and by surface studies involving extensive field sampling and radiometric surveying. These were supplemented by both aerial radiometric and hydrogeochemical and stream-sediment reconnaissance studies. Favorable environments were identified in fluviodeltaic to fan-delta sandstones in the upper Strawn, Canyon, and Cisco Groups (Pennsylvania to Lower Permian), which occur exclusively in the subsurface. Evaluation was based on the presence of a good uranium source, abundant feldspar, good hydrogeologic characteristics, association with carbonaceous shales, presence of coal and oil fields, and anomalies in gamma logs. Additional favorable environments include deltaic to alluvial sandstones in the Wichita-Albany Group (Lower Permian), which crops out widely and occurs in the shallow subsurface. Evaluation was based on high uranium values in stream-sediment samples, a small uranium occurrence located during the field survey, anomalous gamma logs, good uranium source, and hydrogeologic characteristics. Unfavorable environments include Cambrian to Permian limestones and shales. Pennsylvanian to Permian fluviodeltaic systems that have poor uranium sources, and Permian, Cretaceous, and Pleistocene formations that lack features characteristic of known uranium occurrences

    2013-09-01

    Falls among people aged ≥65 years are the leading cause of both injury deaths and emergency department visits for trauma. Research shows that many falls are preventable. In the clinical setting, an effective fall intervention involves assessing and addressing an individual's fall risk factors. This individualized approach is recommended in the American and British Geriatrics Societies' (AGS/BGS) practice guideline. This article describes the development of STEADI (Stopping Elderly Accidents, Deaths, and Injuries), a fall prevention tool kit that contains an array of health care provider resources for assessing and addressing fall risk in clinical settings. As researchers at the Centers for Disease Control and Prevention's Injury Center, we reviewed relevant literature and conducted in-depth interviews with health care providers to determine current knowledge and practices related to older adult fall prevention. We developed draft resources based on the AGS/BGS guideline, incorporated provider input, and addressed identified knowledge and practice gaps. Draft resources were reviewed by six focus groups of health care providers and revised. The completed STEADI tool kit, Preventing Falls in Older Patients-A Provider Tool Kit, is designed to help health care providers incorporate fall risk assessment and individualized fall interventions into routine clinical practice and to link clinical care with community-based fall prevention programs.

  19. Economic Requirements of Water Resources Management

    Full Text Available Indicators of water resources status and water consumption in Iran reveal an imbalance between supply and demand. This is compounded by the current unrealistic water price that signals the inefficiency of the water market in Iran. In economics parlance, the most important factors responsible for the low efficiency of water market are inaccurate valuation and failure to define the ownership rights of water. Low prices, low sensitivity of water demand to prices, and the lack of proper inputs as substitutes for water resources have collectively contributed to excessive pressures on the available water resources for domestic, industrial, and agricultural uses. A brief glance reveals that water resources in Iran are merely priced based on cost accounting. This is while study has shown that developed countries adopt approaches to water pricing that not only consider the final cost of water but also take into account such other parameters that are affected by intrinsic value of water including its bequest and existence values. The present paper draws upon the concepts of value, expenses, and pricing of water in an attempt to explore the marketing and pricing of water resources as the two major tools economists employ in the management of these resources. It is the objective of the study to arrive at an accurate definition of ownership rights of water resources to improve upon the present water marketing. In doing so, the more important components of modern pricing strategies adopted by developed nations will also be investigated. Results indicate that the present cost accounting method used in pricing water in Iran will in the long-run lead to the wastage of water resources and that it should, therefore, be given up in favor modern and more realistic policies to avoid such waste of resources.

    1979-03-01

    The current world energy crisis illustrates the importance of analyzing, as a post-Keynesian approch does, such factors as monopoly power and user costs in trying to understand the production flows and market prices of natural resources - when these flows and prices are changing rapidly and unexpectedly in the face of slowly expanding world output. Post-Keynesian analysts do not immediately see rising natural resource prices as evidence per se that the law of dimmishing returns is operating in perfectly competitive market - or, in other words, that we are running out of cheap energy and other raw materials. A post-Keynesian perspective would instead suggest that such price changes can best be understood (and an appropriate policy response formulated) by analyzing the behavior of entrepreneurial agents and resource property owners in terms of perceived market power and/or expectations about the future. In this connection, Keynes' concept of user cost is a critical one. Keynes recognized that the user cost concept applied not only to raw materials such as fossil fuels, but to all capital equipment, for in deciding his scale of production an entrepreneur has to exercise a choice between using up his equipment now and preserving it to be used later on. For those who adopt the post-Keynesian approach to economic analysis, the decision to utilize natural resouces is viewed as similar to that of disinvestment in capital equipment, while the search for new sources of natural resources is merely a form of capital investment.

    Economic profit could be influenced by economic rents. However natural resource rents provided different impact on the economic growth or economic profit. The main focus of the study was to evaluate the economic growth as function of natural resource rents. For such a purpose machine learning approach, artificial neural network, was used. The used natural resource rents were coal rents, forest rents, mineral rents, natural gas rents and oil rents. Based on the results it is concluded that the machine learning approach could be used as the tool for the economic growth evaluation as function of natural resource rents. Moreover the more advanced approaches should be incorporated to improve more the forecasting accuracy.

  5. Essays in economics of renewable resources

    International Nuclear Information System (INIS)

    Bulte, E.H.

    1997-01-01

    In chapter 2 the basics of renewable resource management are described, based on a brief literature review. Key issues are (1) optimum stock size; (2) approach dynamics; (3) extinction; (4) property rights; and (5) tropical deforestation. Chapter 3 focuses on tropical deforestation in more detail. The distinction between primary, undisturbed forests and secondary, or selectively logged, forests is crucial for understanding deforestation. With a model that explicitly recognizes the transformation of primary forests into secondary forests, the validity of two widely held presumptions is theoretically examined. First, we examine the claim that encroachment is necessarily detrimental for nature conservation. Second, we investigate whether high discount rates accelerate deforestation, as conventional wisdom implies. Chapter 4 also deals with deforestation. The usefulness of providing international transfers to developing countries to promote conservation of tropical forests is examined. In chapter 5 a fairly standard renewable resource model is constructed to study the impact of the trade ban on ivory on the optimum elephant population tion as perceived by the govermnent of African countries. Chapter 6 follows naturally from the previous chapter, where the performance of a trade ban is explored. The central issue is whether, from an economic point of view, trade bans should have been implemented mented in the first place. The case examined relates to commercial (minke) whaling, which has been subject to a commercial moratorium since the mid-1980s. Chapters 7, 8 and 9 are about fisheries policies. Chapter 7 goes back to the property rights problems, discussed in chapter 2. Chapter 8 is a more formal theoretical model of fishing policies. In chapter 9 an instrument is discussed that could be used to facilitate implementation of quota cuts next to other management instruments that have the potential to meet resistance from the sector. Chapters 10 and 11 are based on

    2016-01-01

    It is well documented that falls may be prevented, but effectiveness in reducing the risk of falling depends on the uptake of and the adherence to preventive actions. 65+-year-old fallers identified by screening for fall risk were offered referral to a geriatric fall clinic together with fallers referred from general practitioners (GPs). They were assessed to identify individual risk factors for falling, and appropriate interventions were planned, including exercise classes. A total of 811 persons were identified by screening, 342 of whom accepted referral. Furthermore, 176 were referred from GPs. Only 402 of 518 fallers attended the clinic. A total of 65 dropped out by their own request, 29 stopped because they became seriously ill or died. Another 62 patients were discharged before fulfilling the programme as they were unable to participate due to physical or cognitive problems. Indicators of cessation were cognitive or physical weakness. Geriatric fall prevention is resource-consuming both in terms of staff needed and with respect to demands made on the patients, and the frailest part of the fall population cannot comply. It is necessary to differentiate fall prevention services for the population of elderly fallers as interventions in primary healthcare have been shown to be more effective among the most frail elderly fallers. The project received funding from the Danish Ministry of the Interior and Health and from The Fund for Scientific Work in the Geriatric Field within the former Copenhagen Hospital Corporation. not relevant.

  14. An assessement of global energy resource economic potentials

    International Nuclear Information System (INIS)

    Mercure, Jean-François; Salas, Pablo

    2012-01-01

    This paper presents an assessment of global economic energy potentials for all major natural energy resources. This work is based on both an extensive literature review and calculations using natural resource assessment data. Economic potentials are presented in the form of cost-supply curves, in terms of energy flows for renewable energy sources, or fixed amounts for fossil and nuclear resources, with strong emphasis on uncertainty, using a consistent methodology that allow direct comparisons to be made. In order to interpolate through available resource assessment data and associated uncertainty, a theoretical framework and a computational methodology are given based on statistical properties of different types of resources, justified empirically by the data, and used throughout. This work aims to provide a global database for natural energy resources ready to integrate into models of energy systems, enabling to introduce at the same time uncertainty over natural resource assessments. The supplementary material provides theoretical details and tables of data and parameters that enable this extensive database to be adapted to a variety of energy systems modelling frameworks. -- Highlights: ► Global energy potentials for all major energy resources are reported. ► Theory and methodology for calculating economic energy potentials is given. ► An uncertainty analysis for all energy economic potentials is carried out.

    Application layer networks are software architectures that allow the provisioning of services requiring a huge amount of resources by connecting large numbers of individual computers, like in Grid or Peer-to-Peer computing. Controlling the resource allocation in those networks is nearly impossible using a centralized arbitrator. The network simulation project CATNET will evaluate a decentralized mechanism for resource allocation, which is based on the economic paradigm of th...

    1998-12-01

    Full Text Available Černetič deals with certain dilemmas and problems related to employee training within companies, and discusses the complexity of the relationship between technological development and education, developmental gap between the developed and underdevdoped economies, and the goals of social development in Slovenia. Cernetič stresses that training programmes should above all provide flexibility of employment; the competitive edge of an entire state actually depends on effective use of human resources. Slovenia cannot exert any substantial influence on the global economy, it can only follow the main market trends. Knowledge is therefore of great importance, as the wealth of smaller nations is primarily based on the education level of their inhabitants.

  1. Natural resources endowment and economic growth: The West African Experience

    2013-06-01

    Full Text Available This study aims at investigating the nexus between natural resource endowment and economic growth using a sample of West African countries. The study adopted a Barrow-type growth model to analyse the impact of natural resource wealth on economic growth. A dynamic panel estimation technique was employed using relevant data from West African Countries. The results from the panel regressions indicate that natural resource endowments have very minimal impact in terms of promoting economic growth in West Africa, more so in resource rich countries. In terms of relative effects, the results indicate that a 10% increase in natural resource export reduces growth in income per capita by approximately 0.4%. Part of the factors explaining this finding amongst others; include high corruption in the public sector as well as the frequency of civil conflicts in resource rich economies of West Africa. For the natural resources of the region to fully benefit its citizens, these countries require , urgently, to improve management of natural resource export revenues and to apply effective policy measures to eradicate/ mitigate incidences of rampant corruption in the public sector.

    Over two centuries of economic growth have put undeniable pressure on the ecological systems that underpin human well-being. While it is agreed that these pressures are increasing, views divide on how they may be alleviated. Some suggest technological advances will automatically keep us from transgressing key environmental thresholds; others that policy reform can reconcile economic and ecological goals; while a third school argues that only a fundamental shift in societal values can keep human demands within the Earth’s ecological limits. Here we use novel integrated analysis of the energy-water-food nexus, rural land use (including biodiversity), material flows and climate change to explore whether mounting ecological pressures in Australia can be reversed, while the population grows and living standards improve. We show that, in the right circumstances, economic and environmental outcomes can be decoupled. Although economic growth is strong across all scenarios, environmental performance varies widely: pressures are projected to more than double, stabilize or fall markedly by 2050. However, we find no evidence that decoupling will occur automatically. Nor do we find that a shift in societal values is required. Rather, extensions of current policies that mobilize technology and incentivize reduced pressure account for the majority of differences in environmental performance. Our results show that Australia can make great progress towards sustainable prosperity, if it chooses to do so.

    Full Text Available This presentation describes how the present economic situation can be described in terms of the system dynamics models developed in the series of studies that were titled “The Limits to Growth”. The result of this examination is that mineral depletion may be a major factor in causing the slowdown in economic growth in several countries. The effect is not the result of “running out” of any resource, but of the gradual increase in extraction costs which is forcing the economy to dedicate larger and larger resources to the production of mineral commodities.

  12. [Inventories of the Earth. Mineral resource appraisals and the rise of resource economics].

    Science.gov (United States)

    Westermann, Andrea

    2014-03-01

    How do the earth sciences mediate between the natural and social world? This paper explores the question by focusing on the history of nonfuel mineral resource appraisal from the late nineteenth to the mid twentieth century. It argues that earth sciences early on embraced social scientific knowledge, i.e. economic knowledge, in particular, when it came to determining or deposits and estimating the magnitude of mineral reserves. After 1900, assessing national and global mineral reserves and their "life span" or years of supply became ever more important, scaling up and complementing traditional appraisal practices on the level of individual mines or mining and trading companies. As a consequence, economic methods gained new weight for mineral resource estimation. Natural resource economics as an own field of research grew out of these efforts. By way of example, the mineral resource appraisal assigned to the U.S. Materials Policy Commission by President Harry S. Truman in 1951 is analyzed in more detail. Natural resource economics and environmental economics might be interpreted as a strategy to bring down the vast and holistically conceived object of geological and ecological research, the earth, to human scale, and assimilate it into social matters.

    Full Text Available In the history of the economic growth, there are numerous examples of countries that have developed based on their available natural resources. Especially, these assets have been the propulsion of the development in the initial period. But we also find some cases where countries with limited natural resources have experienced dynamic economic development. Kosovo is the last federal unit dismembered from former Yugoslavia after a decade under Milosevic’s Serbian regime and a two years’ war. International intervention and the inclusion of the country under an international protectorate created the conditions for the development of devastated economy by war and the robbery to be recovered together with the creation of institutional and economic infrastructure (Lidhja e Ekonomistëve të Kosovës, 1996. Under these conditions, everything had to start from scratch. The only development factor that Kosovo possessed was the human factor - age structure and the abundant natural resources, especially in key sectors such as the energy and in mining and minerals, agriculture and tourism. Thus it is sustainable the conclusion that “The rapid and sustainable economic and social development of Kosovo depends substantially from the implementation of the appropriate policies and suitable economic reforms that enable more rational use of its natural and human resources”. The list of the available resources of Kosovo is long. Kosovo possesses significant amount of all mineral raw materials in both quality and quantity terms. Among the most important raw materials have been ranked the power-lignite mining that is stretched into three basins and it is estimated to be around 9 billion exploitable tons (Kelmendi, 2012. Kosovo also owns mineral resources which are found in the Trepca’s Metals basin. The geological researches show favorable conditions of exploitation and high quality of the ore. Mainly one can found the lead, zinc, silver and other

    Falls are one of the most common health problems among older people and pose a major economic burden on health care systems. Exercise is an accepted stand-alone fall prevention strategy particularly if it is balance training or regular participation in Tai chi. Dance shares the 'holistic' approach of practices such as Tai chi. It is a complex sensorimotor rhythmic activity integrating multiple physical, cognitive and social elements. Small-scale randomised controlled trials have indicated that diverse dance styles can improve measures of balance and mobility in older people, but none of these studies has examined the effect of dance on falls or cognition. This study aims to determine whether participation in social dancing: i) reduces the number of falls; and ii) improves cognitive functions associated with fall risk in older people. A single-blind, cluster randomised controlled trial of 12 months duration will be conducted. Approximately 450 participants will be recruited from 24 self-care retirement villages that house at least 60 residents each in Sydney, Australia. Village residents without cognitive impairment and obtain medical clearance will be eligible. After comprehensive baseline measurements including physiological and cognitive tests and self-completed questionnaires, villages will be randomised to intervention sites (ballroom or folk dance) or to a wait-listed control using a computer randomisation method that minimises imbalances between villages based on two baseline fall risk measures. Main outcome measures are falls, prospectively measured, and the Trail Making cognitive function test. Cost-effectiveness and cost-utility analyses will be performed. This study offers a novel approach to balance training for older people. As a community-based approach to fall prevention, dance offers older people an opportunity for greater social engagement, thereby making a major contribution to healthy ageing.

    1994-01-01

    This paper reviews the issues that are critical for the valuation of medical resources in the context of health economic studies. There are several points to consider when undertaking the valuation of medical resources. The perspective of the analysis should be established before determining the valuation process. Future costs should be discounted to present values, and time and effort spent in assigning a monetary value to a medical resource should be proportional to its importance in the analysis. Prices vary considerably based on location of the service and the severity of the illness episode. Because of the wide variability in pricing data, sensitivity analysis is an important component of validation of study results. A variety of data sources have been applied to the valuation of medical resources. Several types of data are reviewed in this paper, including claims data, national survey data, administrative data, and marketing research data. Valuation of medical resources collected in clinical trials is complex because of the lack of standardization of the data sources. A national pricing data source for health economic valuation would greatly facilitate study analysis and make comparisons between results more meaningful.

  16. HUMAN RESOURCE MANAGEMENT IN TERMS OF BEHAVIORAL ECONOMICS

    Full Text Available Behaviourists believe human capital is seen as the potential in people. They believe that the human resource in the organization are intangible assets embodied in the employees, not the people themselves. Behavioral economics emphasizes that people aren’t owned by the company, only their abilities and skills made available to the employer on the basis of certain legal relations which holds it to manage these assets in a rational way. Recognition of behavioral economics also highlights the aspects of development and human capital perspective, which appear in the may resource Staff in the future. These may be limited to: raise, awareness of capacity, internal aspirations, motives. Human capital management is nothing but a recognition of the relevant characteristics of the potential held within the company Staff and correct its use. As a consequence, it can bring tangible benefits to the organization.

    2013-01-01

    We build a general equilibrium model with renewable (non-polluting) and non-renewable (polluting) resources to analyze the interaction and compatibility between economic growth and a cleaner environment. The study is in two phases: (i) resource extraction/production costs are constant; (ii) resource producers invest in knowledge to reduce extraction/production costs, endogenizing technical change. With constant costs, there is a permanent trade-off between economic growth and a cleaner environment. With endogenous technical change, it is possible to harmonize more output and less emissions by replacing non-renewable resources for renewable ones. We also conduct a sensitivity analysis to explore three specific policy actions. With constant costs, the best policy action is the imposition of a higher renewable resources standard, while with endogenous technical change, under certain conditions, all policy interventions may benefit both the economy and the environment. - Highlights: ► Our general equilibrium model includes renewable and non-renewable resources. ► Under constant resource production costs emissions grow at the same rate as output. ► Resource producers can invest in knowledge to reduce production costs. ► Under decreasing costs, lower emissions are compatible with stable output growth. ► Empirical results differ under constant costs and under endogenous technical change

    Full Text Available The issue of lifelong learning is linked to the voluntary and motivated to seek knowledge from personal or organizational reasons. The fact that an individual learns driven by personal career goals, desire for self improvement and motivation refers to the importance of lifelong learning for the entire social inclusion, sustainability, and competitiveness and employment. The common denominator of all the problems of investment in education is an issue of increasing allocations to the social issues, the pace that in this area manifest needs. Relative resource constraints requires that the investment in professional development taking place in accordance with the expected contribution to the creation of new value, increase productivity and social development of society as a whole. Respecting this request, in general, should provide maximum socio-economic effects with minimal investment. Precise measurement is achieved by tools of economic analysis: cost & benefit, economic sensitivity analysis, risk assessment.

  20. Elements for a comprehensive assessment of natural resources: bridging environmental economics with ecological economics

    International Nuclear Information System (INIS)

    Rodriguez Romero, Paulo Cesar; Cubillos Gonzalez, Alexander

    2012-01-01

    The predominance of economic assessments regarding the value of natural resources has caused a sub-valuing of the real benefits which societies can obtain from nature. This is due to a lack of knowledge about the complexity of ecological functions, as well as a dismissal of the integrated relations of the sub-systems which make up the environment. It is therefore necessary to establish conceptual bridges between environmental sciences to fill in the gaps in economic valuation methods by recurring to diverse measuring scales, participation from the different actors involved, and a principle of precaution regarding the limits of nature. This paper explores the concepts of value and economic valuation methods from the perspectives of Environmental Economics and Ecological Economics. It then proposes an integration of valuing methodologies which take into account how complementary and complex natures value relations are. This proposal of valuing integrally ecosystem goods and services contributes to adjusting political decisions more accordingly to real environmental conditions.

    Tools for estimating the cost of developing and operating and maintaining hydropower resources in the form of regression curves were developed based on historical plant data. Development costs that were addressed included: licensing, construction, and five types of environmental mitigation. It was found that the data for each type of cost correlated well with plant capacity. A tool for estimating the annual and monthly electric generation of hydropower resources was also developed. Additional tools were developed to estimate the cost of upgrading a turbine or a generator. The development and operation and maintenance cost estimating tools, and the generation estimating tool were applied to 2,155 U.S. hydropower sites representing a total potential capacity of 43,036 MW. The sites included totally undeveloped sites, dams without a hydroelectric plant, and hydroelectric plants that could be expanded to achieve greater capacity. Site characteristics and estimated costs and generation for each site were assembled in a database in Excel format that is also included within the EERE Library under the title, “Estimation of Economic Parameters of U.S. Hydropower Resources - INL Hydropower Resource Economics Database.”

  3. Natural resource dependence, human capital accumulation, and economic growth: A combined explanation for the resource curse and the resource blessing

    International Nuclear Information System (INIS)

    Shao, Shuai; Yang, Lili

    2014-01-01

    In existing studies, no consensus has been reached on the relationship between natural resource dependence and human capital accumulation. To narrow the divergence, this paper carries out a normative research to explain the co-existence of the phenomena of the resource curse and the resource blessing based on an organic combination of conceptual and mathematical models. It first establishes a conceptual model to analyse the potential effects of the government's policy preference and natural resource development activities on human capital accumulation and economic growth. Furthermore, it develops an endogenous growth model to normatively illuminate the effects in the conceptual model and to explore the condition for the occurrence of the resource curse. The conceptual model analysis indicates that the rate of return on education investment and government behaviours play the crucial role in promoting the formation of the economic virtuous circle at the micro-level and macro-level, respectively, while resource development activities exert dual impacts on the circle. The main mechanisms in the conceptual model can be validated in the mathematical model. The rise in the subjective discount rate, the elasticity of intertemporal substitution, and resource goods price are adverse to the economic virtuous circle, while high-quality education and the institutional environment giving priority to manufacturing can become the necessary condition and sufficient condition for forming the circle, respectively. The allocation efficiency of production factors plays a decisive role in whether the blessing occurs, whereas sufficient human capital is an essential guarantee for evading the curse. - Highlights: • We conduct normative research combining a conceptual model and a mathematical model. • We discuss the potential impact of resource dependence on human capital and growth. • We explain the co-existence of the resource blessing and resource curse phenomena.

  4. Types of Forestry Charges from Natural Resource Economics Perspective

    Full Text Available Capturing economic rent from natural resources, particularly forests, frequently still creates disagreement between the government and businesses. The charges imposed by the government in the forms of reboisation fund (DR and forest resource provision (PSDH have been in place for very long time, accepted by all stakeholders, and supported by laws. Government policy regarding compensation for forest stand value (GRNT creates controvercies. This paper intends to clarify problem of forest charges by returning it to its fundamental theories, e.g. economic theory of natural resouces. Economic rent of forests that are controlled by the government is the right of all Indonesia people.  Henece, the government has responsibility for capturing the rent as much as possible in the most efficient way. If the stumpage is too low then it potentially promotes overcutting, whereas if it is too high then it makes forest business less attractive that potentially promotes illegal activities. In forestry, economic rent of forest has a special name, it is stumpage price. There are some difficulties in estimating a competitive stumpage price, wheter the one obtained through a direct competitive auction of standing timber or through calculation of residual price. Partly, the difficulties were generated by the government’s own policies that strongly distorted log prices. Log export ban and vertical integration are the two most influential policies in distorting log prices. Actually, the government is able to design and implement a single charge to capture PSDH, DR, and GRNT so that their administration becomes much simpler and more efficient.Keywords: stumpage price, soil expectation value, economic rent, production efficient, charge harmonization

    The article substantiates that the effectiveness of implementing socio-economic development strategies is to a large extent determined by the adequate provision of basic resources. The key role of water resources in economic strategic development is empirically illustrated. The article demonstrates the practicability of strategic management of water resources based on the principle of a combination of river basin management approaches and the consideration of regional development strategies. The Game Theory technique was used to develop economic and mathematical tools for supporting decision-making in meeting the needs of regional consumers under water balance deficit conditions. The choice of methods was determined from two positions: the methods should allow for the possibility of multi-variant solutions for the selection of optimal options for the distribution of limited water resources between different consumers; the methods should be orientated on the maximum possible harmonization of multidirectional and multi-scale interests of the subjects in the water management system of the different regions (including the state) in order to achieve a balance. The approbation of developing a toolkit for the example of the regions located in the Don and Kuban river basins resulted in the appropriate selection of priority regions for the allocation of water resources in terms of strategic management as well as the determination of measures of ensuring the sustainable use of the river basins under consideration. The proposed tools can be used for coordinating decisions on the water supply of regional economic systems with actual and projected indicators of socio-economic development of the respective regions for a strategic perspective.

    Non-communicable diseases including type 2 diabetes (T2D) are increasing rapidly in most Sub-Saharan African (SSA) countries like Uganda. Little attention has been given to how patients with T2D try to achieve treatment when the availability of public health care for their disease is limited, as is the case in most SSA countries. In this paper we focus on the landscape of availability of care and the therapeutic journeys of patients within that landscape. Based on fieldwork in south-western Uganda including 10 case studies, we explore the diabetes treatment options in the area and what it takes to access the available treatment. We analyse the resources patients need to use the available treatment options, and demonstrate that the patients' journeys to access and maintain treatment are facilitated by the knowledge and support of their therapy management groups. Patients access treatment more effectively, if they and their family have money, useful social relations, and knowledge, together with the capacity to communicate with health staff. Patients coming from households with high socio-economic status (SES) are more likely to have all of these resources, while for patients with low or medium SES, lack of economic resources increases the importance of connections within the health system.

    Exercise is effective in reducing falls in people with Parkinson disease. However, information on the cost effectiveness of this approach is lacking. We conducted a cost-effectiveness analysis of Tai Ji Quan for reducing falls among patients with mild-to-moderate Parkinson disease. We used data from a previous intervention trial to analyze resource use costs related to intervention delivery and number of falls observed during a 9-month study period. Cost effectiveness was estimated via incremental cost-effectiveness ratio (ICER) in which Tai Ji Quan was compared with 2 alternative interventions (Resistance training and Stretching) on the primary outcome of per fall prevented and the secondary outcome of per participant quality-adjusted life years (QALY) gained. We also conducted subgroup and sensitivity analyses. Tai Ji Quan was more effective than either Resistance training or Stretching; it had the lowest cost and was the most effective in improving primary and secondary outcomes. Compared with Stretching, Tai Ji Quan cost an average of $175 less for each additional fall prevented and produced a substantial improvement in QALY gained at a lower cost. Results from subgroup and sensitivity analyses showed no variation in cost-effectiveness estimates. However, sensitivity analyses demonstrated a much lower ICER ($27) when only intervention costs were considered. Tai Ji Quan represents a cost-effective strategy for optimizing spending to prevent falls and maximize health gains in people with Parkinson disease. While these results are promising, they warrant further validation.

    During the Golden Age of Medicine (20th Century), scientific and technological breakthroughs enabled physicians to cure people's illnesses. The idealist, romantic approach of medical practice believed in the right of every human being to receive the best treatment possible, regardless of cost. However, the rise in health care expenditure at the end of the 20th Century made this impossible, therefore other approaches were adopted. The aim of this study is to investigate the causes of the change in medical approaches while distinguishing between the different methods practiced by nations in order to deal with the disparity created by ethical dilemmas caused by scare resources and delivery of medical treatment. This study is based on the evaluation of macro economic data and the comparison of international health data. Special emphasis was given to the evaluation of Israeli health economics since the National Health Insurance Act (1995). The study shows two different approaches to the problem of scarce resources: the liberal approach, as practiced in the USA, and the Social Democratic approach which is common in many European countries, including Israel. The Social Democratic ideology believes in public financing of defined health care services to all citizens. This method implies rationing and managed care in order to absorb medical expenses. The ethical dilemmas arising from the necessity to add economic considerations to a physician's care of his patient, demand that any given healthcare system find the right equilibrium. This balance between clinical, social, and economical considerations is not easily achieved. Only dialogue within the health care system itself, and with the public, can achieve the best possible balance.

  10. The green paradox of the economics of exhaustible resources

    Cairns, Robert D.

    2014-01-01

    The green paradox states that an increasing tax on emissions of carbon dioxide, consonant with the expected increase in their marginal damages, may induce oil producers to shift their production toward the present and thereby to exacerbate the problem of climatic change. The model is based on Hotelling models of resource use that do not take the natural and technical features of oil production into account. Natural features include the decline of production through time according to a decline curve. Technical features include the requirement to sink investment in productive capacity. A model of a profit-maximizing firm indicates that, if these features are taken into account, the prediction of the green paradox is unlikely. - Highlights: • The green paradox is a direct application of Hotelling′s rule from the economics of exhaustible resources. • Hotelling′s analysis was a profound contribution to economic thought but evidence for it is weak. • Hotelling-style analysis assumes incorrectly that production can be rearranged at will among time periods. • Technological and geological features of oil production make the prediction of the green paradox unlikely

  12. PLANTATION MANAGEMENT AND BAMBOO RESOURCE ECONOMICS IN CHINA

    2014-12-01

    Full Text Available Bamboos constitute a very important and versatile resource worldwide. A lot of Asian, African and South American people rely on bamboo products for their housing and farming tools. Meanwhile, the shoots of these plants are regarded as vegetables in East and South-East Asian nations. China has the greatest bamboo forest area (extension and the largest number of bamboo species (more than 590 species, many of them with significant economic importance, being Moso bamboo (Phyllostachys edulis, the most important bamboo species in China, due to its usage not only as timber but also for food. China has paid unprecedented attention in recent decades to bamboo forest management. The vast economic profits derived from silviculture have contributed much to rural development and poverty alleviation. Bamboo industry has become the pillar of economy in mountainous areas. Besides being a tool for poverty alleviation in rural areas, bamboo plantations are also a significant carbon sink and a key option to mitigate land degradation. This paper highlights such aspects as bamboo silviculture (fertilization, pruning, thinning, irrigation, shoot and timber harvesting its domestic and international applications (timber, plywood, food, paper, fuel, housing, etc. in daily life, and  its current role in Chinese industry and economy, without particular reference to any of its species.

  13. Capturing Economic Rents From Resources Through Royalties and Taxes

    Directory of Open Access Journals (Sweden)

    Jack M. Mintz

    2012-10-01

    Full Text Available Oil price fluctuations, concerns over the division of resource revenues, and unconventional oil and gas developments are forcing governments to confront the same issue: how to design optimal royalty and corporate tax systems that bring in a publicly acceptable share of revenues without discouraging private investment. This paper surveys tax and royalty systems across six countries, as well as four US states and five Canadian provinces, offering concise analyses of their strengths and shortcomings to describe the best and simplest approaches to both. As in a public-private partnership, government owns the resources and allows private agents to maximize the rents resources generate. An optimal royalty system will thus be rent-based, ensuring that both owner and agent obtain maximally competitive returns so that each has incentives to continue the partnership. Such a system will also be simple, making compliance easy, manipulation difficult, and risks affordable. And it will be stable, instilling in the private sector the confidence needed to invest for the long term. As for corporate income taxes, they should be neutral across business activities, and applied at equal effective rates on economic income, to avoid distorting market forces through subsidies or needless complexity. A clean rent-based tax that allows all costs incurred by producers to be expensed or carried over, along with a corporate income tax system shorn of many of the preferences that negatively affect business activity, should be the way forward for any government looking to update their fiscal regimes for the 21st century.

  16. Evaluation of water resource economics within the Pasco Basin, Washington

    International Nuclear Information System (INIS)

    Leaming, G.F.

    1981-01-01

    The Columbia River basalt beneath the Hanford Site in south-central Washington is being considered for possible use as a terminal repository medium for high-level nuclear waste. Such underground storage would require that the facility be contiguous to at least a portion of the ambient groundwater system of the Pasco Basin. This report attempts to evaluate the economic factors and conditions related to the water resources of the Pasco Basin and the probable economic effects associated with selected hypothetical changes in local water demand and supply as a basis for eventual selection of credible water supply alternatives and more detailed analyses of the consequences of such alternative selection. It is most likely that total demand for water for consumptive uses in the Pasco Basin will increase from nearly 2.0 million acre-feet per year in 1980 to almost 2.8 million acre-feet in 2010, with total demand slightly more than 3.6 million acre-feet per year in 2080. The Columbia River and other surface streams constitute the source of more than 99 percent of the water available each year for all uses, both consumptive and non-consumptive, in the Pasco Basin. It is estimated that pumped groundwater accounted for 3 percent of the value of all water supplied to consumers of water in the Pasco Basin in 1980. Groundwater's share of the total cost is proportionately higher than groundwater's share of total use because it is generally more costly to acquire than is surface water and the value of water is considered equivalent to its cost of acquisition. Because groundwater represents such a small part of the total water supply and demand within the Pasco Basin, it is concluded that if the development of a nuclear waste repository on the Hanford Site were to result in changes in the groundwater supply during the next 100 years, the economic impact on the overall water supply picture for the entire basin would be insignificant

    Falls are a costly public health problem worldwide. The literature is devoid of prospective data that identifies factors among fallers that significantly drive health care resource utilization. We found that cognitive function--specifically, executive functions--and cognitive status are significant determinants of health resource utilization among older fallers. Although falls are costly, there are no prospective data examining factors among fallers that drive health care resource utilization. We identified key determinants of health resource utilization (HRU) at 6 and 12 months among older adults with a history of falls. Specifically, with the increasing recognition that cognitive impairment is associated with increased falls risk, we investigated cognition as a potential driver of health resource utilization. This 12-month prospective cohort study at the Vancouver Falls Prevention Clinic (n = 319) included participants with a history of at least one fall in the previous 12 months. Based on their cognitive status, participants were divided into two groups: (1) no mild cognitive impairment (MCI) and (2) MCI. We constructed two linear regression models with HRU at 6 and 12 months as the dependent variables for each model, respectively. Predictors relating to mobility, global cognition, executive functions, and cognitive status (MCI versus no MCI) were examined. Age, sex, comorbidities, depression status, and activities of daily living were included regardless of statistical significance. Global cognition, comorbidities, working memory, and cognitive status (MCI versus no MCI ascertained using the Montreal Cognitive Assessment (MoCA)) were significant determinants of total HRU at 6 months. The number of medical comorbidities and global cognition were significant determinants of total HRU at 12 months. MCI status was a determinant of HRU at 6 months among older adults with a history of falls. As such, efforts to minimize health care resource use related to falls

  19. Current costing models: are they suitable for allocating health resources? The example of fall injury prevention in Australia.

    Science.gov (United States)

    Moller, Jerry

    2005-01-01

    The example of fall injury among older people is used to define and illustrate how current Australian systems for allocation of health resources perform for funding emerging public health issues. While the examples are Australian, the allocation and priority setting methods are common in the health sector in all developed western nations. With an ageing population the number of falls injuries in Australia and the cost of treatment will rise dramatically over the next 20-50 years. Current methods of allocating funds within the health system are not well suited to meeting this coming epidemic. The information requirements for cost-benefit and cost-effectiveness measures cannot be met. Marginal approaches to health funding are likely to continue to fund already well-funded treatment or politically driven prevention processes and to miss the opportunity for new prevention initiatives in areas that do not have a high political profile. Fall injury is one of many emerging areas that struggle to make claims for funding because the critical mass of intervention and evidence of its impact is not available. The beneficiaries of allocation failure may be those who treat the disease burden that could have been easily prevented. Changes to allocation mechanisms, data systems and new initiative funding practices are required to ensure that preventative strategies are able to compete on an equal footing with treatment approaches for mainstream health funding.

    Full Text Available Implementation of the development is often cause adverse environmental impacts. Adverse effects are environmental degradation and decreasing availability of resources. To overcome this, it is necessary that the development can still continue, the environment is not damaged, and the availability of resources is maintained. One effort is through eco - economic decoupling activities with the use of spent resources. The aim of study to determine the potential of spent resources in Central Java, knows the problems in the utilization of spent resources in Central Java, and to determine the impact of the utilization of spent resources in Central Java by a qualitative descriptive method. The results show that in the study have the potential of eco-economic decoupling indicated by the availability of spent resources and had done utilization of spent resources. However, this potential has not been optimally developed, because there are still some problems in its utilization. Problems in the use of spent resources are the lack of knowledge about eco-economic decoupling and spent resources among stakeholder, there is no specific policy on eco - economic decoupling, the lack of Local Government 's role in the utilization of spent resource, and the lack of synergy programs and activities in supporting the utilization of spent resources. Utilization of spent resources have positive impact to reduce pressure on the environment and natural resources, create a new job, and increase incomes for society.

    2012-11-01

    This paper proposes a unified theoretical framework for dealing with the optimum economic use of any type of natural resource. After formulating and economically interpreting the unified framework, the basic rules governing the economic exploitation of the different natural resources can be easily obtained by particularizing the different values of its basic parameters. Taking this approach, it is easy to understand what commonalities there are, in terms of economic logic, between the different types of natural resources. This considerably increases the amount of consilience and understanding about the discipline. (Author) 8 refs.

    There is considerable concern over declines in insect pollinator communities and potential impacts on the pollination of crops and wildflowers. Among the multiple pressures facing pollinators, decreasing floral resources due to habitat loss and degradation has been suggested as a key contributing factor. However, a lack of quantitative data has hampered testing for historical changes in floral resources. Here we show that overall floral rewards can be estimated at a national scale by combining vegetation surveys and direct nectar measurements. We find evidence for substantial losses in nectar resources in England and Wales between the 1930s and 1970s; however, total nectar provision in Great Britain as a whole had stabilized by 1978, and increased from 1998 to 2007. These findings concur with trends in pollinator diversity, which declined in the mid-twentieth century but stabilized more recently. The diversity of nectar sources declined from 1978 to 1990 and thereafter in some habitats, with four plant species accounting for over 50% of national nectar provision in 2007. Calcareous grassland, broadleaved woodland and neutral grassland are the habitats that produce the greatest amount of nectar per unit area from the most diverse sources, whereas arable land is the poorest with respect to amount of nectar per unit area and diversity of nectar sources. Although agri-environment schemes add resources to arable landscapes, their national contribution is low. Owing to their large area, improved grasslands could add substantially to national nectar provision if they were managed to increase floral resource provision. This national-scale assessment of floral resource provision affords new insights into the links between plant and pollinator declines, and offers considerable opportunities for conservation.

    Directory of Open Access Journals (Sweden)

    Aliaksei Igor Patonia

    2017-09-01

    Full Text Available Posing arguments against statistical evidence picturing the European Union as the key world economy, the research views the economic model of the EU through the prism of Hofstede’s cultural dimensions, explaining its lower resistance towards the global economic crisis and comparing it to China – a country with authoritarian governmental methods – that suffered to a significantly lesser extent. Based on the example of these two entities, the paper views the topic of the current refugee crisis in Europe representing it as a new crucial trial for the EU that potentially checks classical economic theory for consistency. According to the author, if found effective, in the foreseeable future it will form a sound basis for further development, if not – it will likely be replaced by the Keynesian paradigm. Thus, with the current refugee crisis in Europe, the author juxtaposes liberal economy with the state-regulated one. This is done to give hints at the importance of the crisis per se, as it is believed to be capable of shattering some of the fundamental principles of the current world order.

    With the development of the society and economy, the contradictions among population, resources and environment are increasingly worse. As a result, the capacity of resources and environment becomes one of the focal issues for many countries and regions. Through investigating and analyzing the present situation and the existing problems of resources and environment in Poyang Lake Eco-economic Zone, seven factors were chosen as the evaluation criterion layer, namely, land resources, water resources, biological resources, mineral resources, ecological-geological environment, water environment and atmospheric environment. Based on the single factor evaluation results and with the county as the evaluation unit, the comprehensive capacity of resources and environment was evaluated by using the state space method in Poyang Lake Eco-economic Zone. The results showed that it boasted abundant biological resources, quality atmosphere and water environment, and relatively stable geological environment, while restricted by land resource, water resource and mineral resource. Currently, although the comprehensive capacity of the resources and environments in Poyang Lake Eco-economic Zone was not overloaded as a whole, it has been the case in some counties/districts. State space model, with clear indication and high accuracy, could serve as another approach to evaluating comprehensive capacity of regional resources and environment.

    The temporal-spatial planning of activities for a territorial fire management program requires knowing the value of forest ecosystems. In this paper we extend to and apply the economic valuation principle to the concept of economic vulnerability and present a methodology for the economic valuation of the forest production ecosystems. The forest vulnerability is analyzed from criteria intrinsically associated to the forest characterization, and to the potential behavior of surface fires. Integrating a mapping process of fire potential and analytical valuation algorithms facilitates the implementation of fire prevention planning. The availability of cartography of economic vulnerability of the forest ecosystems is fundamental for budget optimization, and to help in the decision making process. Published by Elsevier Ltd.

  16. Population Growth, Available Resources, and Quality of Life: China's Post-Reform Economic Development

    Institute of Scientific and Technical Information of China (English)

    Tim Futing Liao; Hua Qin

    2012-01-01

    Two opposing intellectual traditions and their contem- porary developments regarding the relations among population, available resources, and quality of life as reflected in economic growth are reviewed. What is at issue is whether population growth is detrimental to or beneficial for economic development. Neither of the extreme views gives a complete picture of the interplay among population, resources, and quality of life. Following previ- ous literature on the topic, this paper establishes a more balanced approach that considers the function linking population and quality of life not constant but variable and regards the limitedness of resources as not absolute but relative to regions and societies. The proposed approach is more flexible in better explaining the relation between population and economic growth. China is examined as a case in point to shed light on the interaction of population growth, economic development, and available resources, and its recent post-economic reform experiences showcase the appropriateness of the synthetic approach.

    Full Text Available The aim of the article is to reveal the influence of geo-economic transformations on the trends in international migration of human resources as an element of the resource potential of countries and regions. The current state of geo-economic transformations is analyzed, and their influence on the processes of international migration of human resources is revealed. The relevance of analyzing international movement of human resources, not labor ones, in building the geo-economic strategy of a country or a regional grouping is justified. The connection between the international migration of human resources and the trends in development of individual countries and regions (oil exporting countries, newly industrialized countries and least developed agrarian countries is determined, the general patterns of migration flows in these countries are described. Furthermore, the topical issues in studying international migration of human resources in the context of the directions of geo-economics identified by scientists are formulated. It is determined that the regional migration policy should contribute to maximizing the benefits of migration of human resources for the development of the region and the use of immigrants in the countries of the region as an economic resource that becomes strategically important under conditions of geo-economic transformations.

    1993-01-28

    Large-scale use of geothermal energy is likely to result in depletion of natural resources that support both biodiversity and other human uses. Most of the problems could be averted with competent planning and adherence to agreed conditions, but they commonly develop because they are not perceived to be directly geothermal in origin and hence are not taken into account adequately. Some of the implications of such issues are discussed below, with particular reference to countries where all or most resources are held under traditional principals of custom ownership.

  7. Intraspecific Autochthonous and Allochthonous Resource Use by Zooplankton in a Humic Lake during the Transitions between Winter, Summer and Fall.

    Directory of Open Access Journals (Sweden)

    Martin Berggren

    Full Text Available Seasonal patterns in assimilation of externally produced, allochthonous, organic matter into aquatic food webs are poorly understood, especially in brown-water lakes. We studied the allochthony (share biomass of terrestrial origin in cladoceran, calanoid and cyclopoid micro-crustacean zooplankton from late winter to fall during two years in a small humic lake (Sweden. The use of allochthonous resources was important for sustaining a small population of calanoids in the water column during late winter. However, in summer the calanoids shifted to 100% herbivory, increasing their biomass several-fold by making efficient use of the pelagic primary production. In contrast, the cyclopoids and cladocerans remained at high levels of allochthony throughout the seasons, both groups showing the mean allochthony of 0.56 (range in mean 0.17-0.79 and 0.34-0.75, for the respective group, depending on model parameters. Our study shows that terrestrial organic matter can be an important resource for cyclopoids and cladocerans on an annual basis, forming a significant link between terrestrial organic matter and the higher trophic levels of the food web, but it can also be important for sustaining otherwise herbivorous calanoids during periods of low primary production in late winter.

    Diffusion of hydrogen as an energetic vector meets with a lot of obstacles that don't depend on available raw material, but on hydrogen combination with other elements. It is necessary, therefore, to separate hydrogen picking out the available different technologies to have different pure hydrogen of variable quantities. Besides, its diffusion as fuel is limited because of the great production cost compared to fuels sprung from petroleum. Hydrogen used on a large scale could have advantages on the environment and occupation, but there are economic and politic obstacles to limit its diffusion. Future of economic system, based on hydrogen as the main energetic vector, will depend on the programme that national and international qualified governing bodies will be able to do [it

  12. Public enterprises in natural resource industries: an economic analysis

    International Nuclear Information System (INIS)

    Fulton, M.E.

    1985-01-01

    Public enterprises are playing an ever increasing role in natural resource industries. This research analyzes the reason for this involvement, i.e., what have been the objectives of public firms, the objectives of other firms; and the reasons behind exploration in natural resource industries. An answer to the first question was obtained by estimating the objective function of a publicly owned uranium company operating in Saskatchewan, Canada. It was assumed the company solved a linear quadratic optimal control problem. The conclusion was that over the period 1974-1984 the company preferred to trade off profits for higher employment, larger reserve holdings, and greater output. The objectives of the other firms in the Saskatchewan uranium industry were also investigated. It was found that producers integrated with utilities can expect to make a much greater rate of return on exploration that nonintegrated producers, since the former group stands to gain both from the reduction in costs and the reduction in price resulting from exploration. The suggests that overinvestment in the Saskatchewan uranium industry may be a problem. The final item investigated is the normative question of what the objective of a public firm operating alongside a private firm in an oligopolistic industry should be in order that resources in the industry are used efficiently; the answer to this question depends upon the structure of the industry

    Sun, the ultimate energy resource of our planet, transfers energy to the Earth at an average power of 23,000 TW. Earth surface can be regarded as a huge panel transforming solar energy into a more convenient mechanical form, the wind. Since millennia wind is recognized as an exploitable form of energy and it is common knowledge that the higher you go, the stronger the winds flow. To go high is difficult; however Bill Gates cites high wind among possible energy miracles in the near future. Public awareness of this possible miracle is still missing, but today's technology is ready for it.

    We specify a dynamic programming model that addresses the interplay among health, financial resources, and the labor market behavior of men late in their working lives. We model health as a latent variable, for which self reported disability status is an indicator, and allow self-reported disability to be endogenous to labor market behavior. We use panel data from the Health and Retirement Study. While we find large impacts of health on behavior, they are substantially smaller than in models that treat self-reports as exogenous. We also simulate the impacts of several potential reforms to the Social Security program. PMID:27158180

    This report comprises an initial economic and market appraisal of the proposals made by Materials Recycling Management (MRM) Ltd for a commercial plant engaged in waste treatment and energy recovery. The MRM design is an integrated waste handling system for commercial and industrial non hazardous wastes and civic amenity wastes. After primary separation into three selected broad waste categories, wastes are processed in the plant to recover basic recyclables such as paper, timber, plastics and metals. A quantity of material is directed for composting and the remainder converted into a fuel and combusted on site for energy recovery. Wastes unworthy of processing would be sent for disposal. A basic technical review has been undertaken. The focus of this review has been on the main processing plant where materials are segregated and the fuel and compost produced. (author)

    2015-03-01

    Full Text Available This article introduces the key problems of social-economic development of Tomsk region and factors that influence economic growth in highly resource-dependent region. Authors prove the advisability of using cognitive approach for investigation and forecasting of social-economic system development in conditions of uncertainty. Also results of simulation are given medium-term forecast. They are interpreted by means of fuzzy cognitive map. Obtained results, on the one hand, confirm the theoretical considerations about the need of convergence between various factors in the regional development strategy. On the other hand, it’s revealed the need to build a normative model, showing what the regional economy should be. This will allow to conceive more clearly the direction of movement from the modern position to desired one and to determine required contours of the economic policy.

T his study e xplore s how continued depletions of the High Plains Aquifer might impact both critical infrastructure and the economy at the local, r egional , and national scale. This analysis is conducted at the county level over a broad geographic region within the states of Kansas and Nebraska. In total , 140 counties that overlie the High Plains Aquifer in these two states are analyzed. The analysis utilizes future climate projections to estimate crop production. Current water use and management practices are projected into the future to explore their related impact on the High Plains Aquifer , barring any changes in water management practices, regulat ion, or policy. Finally, the impact of declining water levels and even exhaustion of groundwater resources are projected for specific sectors of the economy as well as particular elements of the region's critical infrastructure.

  4. Essays on environmental, energy, and natural resource economics

    Science.gov (United States)

    Zhang, Fan

    My dissertation focuses on examining the interrelationship among the environment, energy and economic development. In the first essay, I explore the effects of increased uncertainty over future output prices, input costs and productivity levels on intertemporal emission permits trading. In a dynamic programming setting, a permit price is a convex function of each of these three sources of uncertainty. Increased uncertainty about future market conditions increases the expected permit price and causes risk-neutral firms to reduce ex ante emissions to smooth marginal abatement costs over time. Empirical analysis shows that increased price volatility induced by electricity market restructuring could explain 8-11% of the allowances banked during Phase I of the U.S. sulfur dioxide trading program. Numerical simulation suggests that high uncertainty may generate substantial initial compliance costs, thereby deterring new entrants and reducing efficiency; sharp emission spikes are also more likely to occur under industry-wide uncertainty shocks. In the second essay, I examine whether electricity restructuring improves the efficiency of U.S. nuclear power generation. Based on the full sample of 73 investor-owned nuclear plants in the United States from 1992 to 1998, I estimate cross-sectional and longitudinal efficiency changes associated with restructuring, at the plant level. Various modeling strategies are presented to deal with the policy endogeneity bias that high cost plants are more likely to be restructured. Overall, I find a strikingly positive relationship between the multiple steps of restructuring and plant operating efficiency. In the third essay, I estimate the economic impact of China's national land conversion program on local farm-dependent economies. The impact of the program on 14 industrial sectors in Gansu provinces are investigated using an input-output model. Due to regulatory restrictions, the agricultural sector cannot automatically expand or shrink

  5. Regional Economic Resilience: Resistance and Recoverability of Resource-Based Cities during Economic Crises in Northeast China

    Full Text Available This paper quantitatively analyzes the economic resilience of resource-based cities (RBCs in Northeast China in terms of resistance and recoverability during two economic crises: the Asian financial crisis and the global financial crisis. Moreover, it analyzes the main factors that affected regional resilience. There are three main findings. First, the RBCs in general demonstrated poor resistance during both recessions, but there were variations among the different types of RBCs. Petroleum and metal cities demonstrated the most resistance, whereas coal cities performed the worst. Second, the influential factors affecting economic resilience varied across the two economic cycles, but location advantage, research and development (R and D intensity, foreign trade dependence ratio, and supporting policies had positive effects on resilience during both economic cycles, while the proportion of employed persons in resource industries had a negative effect. Industrial diversity had a weak and ambiguous effect on resilience. Third, the secondary industry was more resilient during the Asian financial crisis, but the tertiary industry was more resilient during the global financial crisis. This shift may be attributed to both the nature of the crises and the strength of the sectors at the time of the crises.

    While the "social determinants of health" view compels us to explore how social structures shape health outcomes, it often ignores the role individual agency plays. In contrast, approaches that focus on individual choice and personal responsibility for health often overlook the influence of social structures. Amartya Sen's "capabilities" framework and its derivative the "health capabilities" (HC) approach attempts to accommodate both points of view, acknowledging that individuals function under social conditions over which they have little control, while also acting as agents in their own health and well-being. This paper explores how economic, social, and cultural resources shape the health capability of people with diabetes, focusing specifically on dietary practices. Health capability and agency are central to dietary practices, while also being shaped by immediate and broader social conditions that can generate habits and a lifestyle that constrain dietary behaviors. From January 2011 to December 2012, we interviewed 45 people with diabetes from a primary care clinic in Ontario (Canada) to examine how their economic, social, and cultural resources combine to influence dietary practices relative to their condition. We classified respondents into low, medium, and high resource groups based on economic circumstances, and compared how economic resources, social relationships, health-related knowledge and values combine to enhance or weaken health capability and dietary management. Economic, social, and cultural resources conspired to undermine dietary management among most in the low resource group, whereas social influences significantly influenced diet among many in the medium group. High resource respondents appeared most motivated to maintain a healthy diet, and also had the social and cultural resources to enable them to do so. Understanding the influence of all three types of resources is critical for constructing ways to enhance health capability, chronic

    Coastal and other area resources such as tidal wetlands, seagrasses, coral reefs, wetlands, and other ecosystems are often harmed by environmental damage that might be inflicted by human actions, or could occur from natural hazards such as hurricanes. Society may wish to restore resources to offset the harm, or receive compensation if this is not possible, but faces difficult choices among potential compensation projects. The optimal amount of restoration efforts can be determined by non-market valuation methods, service-to-service, or resource-to-resource approaches such as habitat equivalency analysis (HEA). HEA scales injured resources and lost services on a one-to-one trade-off basis. Here, we present the main differences between the HEA approach and other non-market valuation approaches. Particular focus is on the role of the social discount rate, which appears in the HEA equation and underlies calculations of the present value of future damages. We argue that while HEA involves elements of economic analysis, the assumption of a one-to-one trade-off between lost and restored services sometimes does not hold, and then other non-market economic valuation approaches may help in restoration scaling or in damage determination.

  8. Values of Land and Renewable Resources in a Three-Sector Economic Growth Model

    Directory of Open Access Journals (Sweden)

    Zhang Wei-Bin

    2015-04-01

    Full Text Available This paper studies dynamic interdependence of capital, land and resource values in a three sector growth model with endogenous wealth and renewable resources. The model is based on the neoclassical growth theory, Ricardian theory and growth theory with renewable resources. The household’s decision is modeled with an alternative approach proposed by Zhang two decades ago. The economic system consists of the households, industrial, agricultural, and resource sectors. The model describes a dynamic interdependence between wealth accumulation, resource change, and division of labor under perfect competition. We simulate the model to demonstrate the existence of a unique stable equilibrium point and plot the motion of the dynamic system. The study conducts comparative dynamic analysis with regard to changes in the propensity to consume resources, the propensity to consume housing, the propensity to consume agricultural goods, the propensity to consume industrial goods, the propensity to save, the population, and the output elasticity of capital of the resource sector.

    Where strong water rights law and corresponding markets exist as a coupled econo-legal mechanism, water rights holders are permitted to trade allocations to promote economic water resource use efficiency. In locations where hydrologic uncertainty drives the assignment of annual per-water right allocation values by water resource managers, collaborative water resource decision making by water rights holders, specifically those involved in agricultural production, can result in both resource and economic Pareto efficiency. Such is the case in semi-arid North Chile, where interactions between representative farmer groups, treated as competitive bilateral monopolies, and modeled at water market-scale, can provide both price and water right allocation distribution signals for unregulated, temporary water right leasing markets. For the range of feasible per-water right allocation values, a coupled agricultural-economic model is developed to describe the equilibrium distribution of water, the corresponding market price of water rights and the net surplus generated by collaboration between competing agricultural uses. Further, this research describes a per-water right inflection point for allocations where economic efficiency is not possible, and where price negotiation among competing agricultural uses is required. An investigation of the effects of water right supply and demand inequality at the market-scale is completed to characterize optimal market performance under existing water rights law. The broader insights of this research suggest that water rights holders engaged in agriculture can achieve economic benefits from forming crop-type cooperatives and by accurately assessing the economic value of allocation.

    1996-01-01

    Petroleum resources have an important influence on the economic life in Norway. To the official authorities it is therefore essential to have good and detailed knowledge of these resources. Questions like 'what are the total resources', 'how much of the resources have been produced' and 'how much is expected to remain' should be answered. A classification system and an updated resource account is therefore required. Even though there is currently a well defined classification system and a resource account which is annually updated, estimates of discovered resources are associated with considerable uncertainty for some fields and discoveries. The uncertainties are not only connected to the mapping of field sizes but also to the possible potential for improved recovery, particularly in the light of new or sophisticated recovery methods. During the last two years the Norwegian Petroleum Directorate (NPD) has paid considerable attention to the potential for improved oil recovery. This is because of the time-critical aspects in the producing fields. The assessment of undiscovered resources also includes large uncertainties. However, regardless of the uncertainties such assessments are important for long term national planning. Decisions concerning opening of new areas for future exploration will have a considerable impact on the future level of the petroleum activities. To national authorities it is therefore important to have an understanding of what economic potential the undiscovered resources may represent. To resource analysts it will be important to know how the results from the geological assessments are uses in the economic calculations. Different resource assessments of a single play model are compared, and a comparison between different prospect evaluations of one single prospect are also presented. This approach is used to focus on the most critical uncertainty factors. 8 refs

    Full Text Available Abstract Background Cost of illness studies show that Parkinson disease (PD is costly for individuals, the healthcare system and society. The costs of PD include both direct and indirect costs associated with falls and related injuries. Methods This protocol describes a prospective economic analysis conducted alongside a randomised controlled trial (RCT. It evaluates whether physical therapy is more cost effective than usual care from the perspective of the health care system. Cost effectiveness will be evaluated using a three-way comparison of the cost per fall averted and the cost per quality adjusted life year saved across two physical therapy interventions and a control group. Conclusion This study has the potential to determine whether targetted physical therapy as an adjunct to standard care can be cost effective in reducing falls in people with PD.

    Full Text Available This paper is a documentation of the tangible economic benefits that accrued to the town of Victoria Falls, Zimbabwe, by co-hosting with Zambia, the 20th session of the United Nations World Tourism Organisation (UNWTO General Assembly (GA in 2013. The paper intends to offset speculations, half-truths and exaggerations on the tangible economic benefits of the event to the town and to contribute significantly to the scanty existing literature on the impact of these events to developing countries. A single case study research design focusing on the town was adopted for this study. The study participants to the research included tourism and hospitality organizations, the Victoria Falls municipality authorities, service providers and Victoria Falls town residents. Researcher administered questionnaires, semi-structured interviews and observation check lists were used to collect the data. In general, although the GA brought some significant transformative effects to the town of Victoria Falls in terms of employment creation, infrastructural development, revenue generation and the country's image, future host cities and countries to this event should mobilize adequate funds for the event, time it appropriately, ensure a fair spread of the benefits to various sectors and put up structures that do not turn into white elephants soon after the event.

    Full Text Available This paper studies current models on sustainable economic growth with resource constraints and explores to what extent resource constraints can be overcome by substitution and technological change. We also study the problem of intergenerational equity and the different criteria that have been suggested in the literature. The central part of this paper is the presentation of stylized facts on exhaustible resources and an estimation of a basic model with resource constraints for US time series data. The estimated years left until depletion and the empirical trends of the ratios of capital stock and consumption to resources seem to indicate that there might be a threat to sustainable growth in the future. In our estimation, we obtain parameter values, which help to interpret the extent to which growth with exhaustible resources is sustainable.

    Hydro-economic models have been used to analyze optimal supply management and groundwater use for the past 25 years. They are characterized by an objective function that usually maximizes economic measures such as consumer and producer surplus subject to hydrologic equations of motion or water distribution systems. The hydrologic and economic components are sometimes fully integrated. Alternatively they may use an iterative interactive process. Environmental considerations have been included in hydro-economic models as inequality constraints. Representing environmental requirements as constraints is a rigid approximation of the range of management alternatives that could be used to implement environmental objectives. The next generation of hydro-economic models, currently being developed, require that the environmental alternatives be represented by continuous or semi-continuous functions which relate water resource use allocated to the environment with the probabilities of achieving environmental objectives. These functions will be generated by process models of environmental and biological systems which are now advanced to the state that they can realistically represent environmental systems and flexibility to interact with economic models. Examples are crop growth models, climate modeling, and biological models of forest, fish, and fauna systems. These process models can represent environmental outcomes in a form that is similar to economic production functions. When combined with economic models the interacting process models can reproduce a range of trade-offs between economic and environmental objectives, and thus optimize social value of many water and environmental resources. Some examples of this next-generation of hydro-enviro- economic models are reviewed. In these models implicit production functions for environmental goods are combined with hydrologic equations of motion and economic response functions. We discuss models that show interaction between

    The accelerated development in Peer-to-Peer (P2P) and Grid computing has positioned them as promising next generation computing platforms. They enable the creation of Virtual Enterprises (VE) for sharing resources distributed across the world. However, resource management, application development and usage models in these environments is a complex undertaking. This is due to the geographic distribution of resources that are owned by different organizations or peers. The resource owners of each of these resources have different usage or access policies and cost models, and varying loads and availability. In order to address complex resource management issues, we have proposed a computational economy framework for resource allocation and for regulating supply and demand in Grid computing environments. The framework provides mechanisms for optimizing resource provider and consumer objective functions through trading and brokering services. In a real world market, there exist various economic models for setting the price for goods based on supply-and-demand and their value to the user. They include commodity market, posted price, tenders and auctions. In this paper, we discuss the use of these models for interaction between Grid components in deciding resource value and the necessary infrastructure to realize them. In addition to normal services offered by Grid computing systems, we need an infrastructure to support interaction protocols, allocation mechanisms, currency, secure banking, and enforcement services. Furthermore, we demonstrate the usage of some of these economic models in resource brokering through Nimrod/G deadline and cost-based scheduling for two different optimization strategies on the World Wide Grid (WWG) testbed that contains peer-to-peer resources located on five continents: Asia, Australia, Europe, North America, and South America.

    To describe the resources and strategies required to establish a health outcomes and economics center in radiology.Methods. Human and nonhuman resources required to perform sound outcomes and economics studies in radiology are reviewed.Results. Human resources needed include skilled medical and nonmedical staff. Nonhuman resources required are: (1) communication and information network; (2) education tools and training programs; (3) budgetary strategies; and (4) sources of income. Effective utilization of these resources allows the performance of robust operational and clinical research projects in decision analysis, cost-effectiveness, diagnostic performance (sensitivity, specificity, and ROC curves), and clinical analytical and experimental studies.Conclusion. As new radiologic technology and techniques are introduced in medicine, society is increasingly demanding sound clinical studies that will determine the impact of radiologic studies on patient outcome. Health-care funding is scarce, and therefore third-party payers and hospitals are demanding more efficiency and productivity from radiologic service providers. To meet these challenges, radiology departments could establish health outcomes and economics centers to study the clinical effectiveness of imaging and its impact on patient outcome. (orig.)

  6. Linguistic confusion in economics: utility, causality, product differentiation, and the supply of natural resources.

    Science.gov (United States)

    Simon, J L

    1982-01-01

    Lack of careful attention to the language used in the discussion of economic concepts has resulted in considerable confusion and error. 2 frequent sources of confusion include tautology and the absence of operational definitions of concepts. This paper outlines a more effective scientific practice through reference to 2 economic examples: 1) the concept of utility, where it is demonstrated that choice of an operational definition of the concept facilitates interpersonal comparisons; and 2) causality, where a multidimensional operational definition is needed to discriminate among the various meanings of the term in theoretical, empirical, and policy contexts. The paper further discusses the example of natural resource scarcity, where application of the term "finite" reveals that there is no empirical evidence of physical limits to growth in the use of resources. A more appropriate measure of scarcity is the economic concept of price.

    When people are morally convicted regarding a specific issue, these convictions exert a powerful influence on their attitudes and behavior. In the current research we examined whether there are boundary conditions to the influence of this effect. Specifically, whether in the context of salient economic rewards, moral convictions may become weaker predictors of attitudes regarding resource use. Focusing on the issue of mining we gathered large-scale samples across three different continents (Australia, Chile, and China). We found that moral convictions against mining were related to a reduced acceptance of mining in each country, while perceived economic rewards from mining increased acceptance. These two motivations interacted, however, such that when perceived economic benefit from mining was high, the influence of moral conviction was weaker. The results highlight the importance of understanding the roles of both moral conviction and financial gain in motivating attitudes towards resource use.

    1990-01-01

    This paper reports on New Mexico's low-temperature geothermal resources which have been utilized to promote economic development initiatives within the state. Public funds have been leveraged to foster exploration activities which have led to the establishment of several direct-use projects at various sites within New Mexico. State policies have focused on attracting one business sector, the commercial greenhouse industry, to expand and/or relocate in New Mexico. Geothermal-related promotional activities have begun to show success in achieving economic growth. New Mexico now has almost half of the geothermally-heated greenhouse space in the nation. It is anticipated that the greenhouse sector will continue to grow within the state. Future economic development activities, also relying upon the geothermal resource base, will include vegetable dehydration and aquaculture with a focus on the microalgae sector

    2017-12-01

    The limited water resources available for irrigation are a key constraint for the important agricultural sector of Colorado's economy. As climate change and groundwater depletion reshape these resources, it is essential to understand the economic potential of water resources under different agricultural production practices. This study uses a linear programming optimization at the county spatial scale and annual temporal scales to study the optimal allocation of water withdrawal and crop choices. The model, AWASH, reflects streamflow constraints between different extraction points, six field crops, and a distinct irrigation decision for maize and wheat. The optimized decision variables, under different environmental, social, economic, and physical constraints, provide long-term solutions for ground and surface water distribution and for land use decisions so that the state can generate the maximum net revenue. Colorado, one of the largest agricultural producers, is tested as a case study and the sensitivity on water price and on climate variability is explored.

    2013-01-01

    Resource-based cities in China have made momentous contributions to the development of the national economy for decades. However, with the depletion of natural resources, their sustainable development is challenging and transition is important. The Chinese government has made great efforts to help resource-based cities. The purpose of this study is to investigate transition policies and their implementation. Firstly, we reviewed previous studies and summarized the essential elements of some successful resource-based cities, which are useful experiences for Chinese resource-based cities. Secondly, we studied the development of resource-based cities over the past 10 years with a focus on economic development, industrial structure, government revenue and environmental conditions. We found that resource-based cities were less developed compared to other cities. The main reasons are the after-effects of a planned economy, an unreasonable tax system, planning mistakes and misguided resources exploitation policies. Thirdly, we analyzed several aspects of the policy responses after the introduction of transition policies, including designating 69 resource-exhausted cities, supporting cities with funds and projects, formulating transition plans and evaluating transition performance. However, there are some deficiencies in the process of policy implementation. Finally, some recommendations were provided to improve transition performance and sustainable development for resource-based cities. - Highlights: ► Analyze the development of Chinese resource-based cities from four aspects. ► Analyze the causes of less development in resource-based cities. ► Investigate policies and their responses to transformation. ► Provide recommendations to improve transformation performance and sustainable development

    Full Text Available Peculiarities of land market formation and peculiarities of its function in modern (up-to-date environment are covered in this article. The objective necessity of governmental regulation is shown. In authors opinion the economic regulation of land market is the most important part of the system. Economic regulation mechanism is realized in correlation with economic land evaluation. Cadastre evaluation that is applied today does not reflect the true land value, but it is used as a basis for the land rent rat estimation and the initial selling price. The alternative way of land resource evaluation that is offered in the article reflects the change of country economic situation more real and is able to influence objectively on the land relations regulation decision making process.

    2014-01-01

    District energy (DE) systems provide an important means of mitigating greenhouse gas emissions and the significant related concerns associated with global climate change. DE systems can use fossil fuels, renewable energy and waste heat as energy sources, and facilitate intelligent integration of energy systems. In this study, an enviro-economic function is developed for assessing various energy sources for a district energy system. The DE system is assessed for the considered energy resources by considering two main factors: CO 2 emissions and economics. Using renewable energy resources and associated technologies as the energy suppliers for a DE system yields environmental benefits which can lead to financial advantages through such instruments as tax breaks; while fossil fuels are increasingly penalized by a carbon tax. Considering these factors as well as the financial value of the technology, an analysis approach is developed for energy suppliers of the DE system. In addition, the proposed approach is modified for the case when thermal energy storage is integrated into a DE system. - Highlights: • Developed a function to assess various energy sources for a district energy system. • Considered CO 2 emissions and economics as two main factors. • Applied renewable energy resources technologies as the suppliers for a DE system. • Yields environmental benefits can lead to financial benefits by tax breaks. • Modified enviro-economic function for the TES integrated into a DE system

    2014-05-01

    The development of more refined information tools is a pre-requisite for supporting decision making in the context of integrated water resources management. Among these tools, hydro-economic models are favoured because they allow integrating the ecological, hydrological, infrastructure and economic aspects into a coherent, scientifically-informed framework. We present a case study that assesses physically the water resources of forest lands of the Andalusia region in Spain and conducts an economic environmental income and asset valuation of the forest surface water yield. We show how, based on available hydrologic and economic data, we can develop a comprehensive water account for all the forest lands at the regional scale. This forest water environmental valuation is part of the larger RECAMAN project, which aims at providing a robust and easily replicable accounting tool to evaluate yearly the total income an capital generated by the forest land, encompassing all measurable sources of private and public incomes (timber and cork production, auto-consumption, recreational activities, biodiversity conservation, carbon sequestration, water production, etc.). Only a comprehensive integrated tool such as the one built within the RECAMAN project may serve as a basis for the development of integrated policies such as those internationally agreed and recommended for the management of water resources.

  16. Oil and Water: Essays on the Economics of Natural Resource Usage

    Science.gov (United States)

    Stolper, Samuel

    As the developing world continues its pace of rapid growth and the threat of climate change intensifies, the economics of natural resource usage become increasingly important. From the perspective of both economic efficiency and distributional equity, effective policy design is correspondingly urgent. Market failures such as imperfect competition, externalities, and incomplete information plague resource markets everywhere; and both initial endowments and policy interventions often have regressive incidence. I shed light on some of these issues by studying the economics of natural resource usage in two separate empirical contexts. The first is the market for automotive fuel in Spain; I measure pass-through--the degree to which retail fuel stations "pass through" diesel taxes to final consumer prices--and use it assess the distributional impacts of energy policy. The second is the Ganga River Basin of India; I estimate the impacts of environmental regulation on river water quality and infant mortality. In both contexts, I utilize estimates of policy impacts to examine the underlying mechanisms by which affected consumers and suppliers of natural resources make decisions.

    Highlights: • We conduct the thermodynamic and economic analysis of various geothermal power cycles. • The optimization process was performed to minimize the exergy losses. • Kalina cycle is a new technology compared to flash and binary cycles. • It is shown that Kalina cycle presents a viable choice for both thermodynamically and economically. - Abstract: Geothermal power generation technologies are well established and there are numerous power plants operating worldwide. Turkey is rich in geothermal resources while most resources are not exploited for power production. In this study, we consider geothermal resources in Kutahya–Simav region having geothermal water at a temperature suitable for power generation. The study is aimed to yield the method of the most effective use of the geothermal resource and a rational thermodynamic and economic comparison of various cycles for a given resource. The cycles considered include double-flash, binary, combined flash/binary, and Kalina cycle. The selected cycles are optimized for the turbine inlet pressure that would generate maximum power output and energy and exergy efficiencies. The distribution of exergy in plant components and processes are shown using tables. Maximum first law efficiencies vary between 6.9% and 10.6% while the second law efficiencies vary between 38.5% and 59.3% depending on the cycle considered. The maximum power output, the first law, and the second law efficiencies are obtained for Kalina cycle followed by combined cycle and binary cycle. An economic analysis of four cycles considered indicates that the cost of producing a unit amount of electricity is 0.0116 $/kW h for double flash and Kalina cycles, 0.0165 $/kW h for combined cycle and 0.0202 $/kW h for binary cycle. Consequently, the payback period is 5.8 years for double flash and Kalina cycles while it is 8.3 years for combined cycle and 9 years for binary cycle

    In our country, within the studies, on which the development strategies of power output are based on, the assessment of the economical efficiency of the use of two main energetic resources, the fuel used in cogeneration thermal power plants and the water used in hydropower plants respectively, was made in compliance with non-unitary specific norms. In contradiction with the degree of utilization of hydroelectric resources, realized all over the world in the developed countries (80-90%) resulted that in our country, where the degree of utilization is only 40%, the use of hydroelectric potential is not yet justified from technical-economical point of view. This anomaly was determined by the cause of non-unitary assessment of the economic efficiency for the cogeneration thermo-power plants and hydropower plants. This paper presents comparatively the elements, which were to the basis of the assessment of the economic efficiency for two types of electrical power plants, and one presents a proposal in the aim to perform a unitary assessment of the economical efficiency by applying efficiently the laws in force.

    Full Text Available The Yamal region occupies the fifth part of the Yamal-Nenets Autonomous District. Therefore it is one of the territories where traditional natural resource management is mainly developing. Its key branches are reindeer herding and fisheries. The major problems in the development of industries are due to an active industrial and transport exploitation of the tundra zone; the situation in reindeer husbandry caused by pasture overgrazing because of uncontrolled increase in livestock; poaching fish. Two following anthropogenic factors have a negative impact on soil and vegetation in the Yamal region: reindeer herding as the main traditional form of natural resource management of Small Indigenous People of the North (SIPN and the intensive industryrelated development of the territory (geological exploration, industry, transport, construction. Since grazing is practiced throughout the whole Yamal Peninsula, which is not occupied by industrial zones, it is the most widespread form of natural resource use and the leading factor of anthropogenic impact on Yamal’s natural territorial complexes. The primary reason for the decline in fish resources is the violation of the ecosystemic reproduction of fish resources due to their excessive catch. One of the main reasons of this is poaching. In turn, the annual increase of surplus catch is caused by the population growth, including SIPN, and the growing density of the road network providing the access to fishing grounds. The article offers the guidelines for economic damage assessment determined by the harm to the pasture resources. The authors justify the amount of compensation that repairs losses arising from their damage, which takes into account the decline in the productivity of land and the period of restoration of the economic and biological potential of pastures for the corresponding periods of years (compensation for economic damage.

  4. Economic development, income inequality and environmental degradation of fisheries resources in Mauritius.

    Science.gov (United States)

    Sobhee, Sanjeev K

    2004-07-01

    This article examines how environmental degradation of fisheries resources in the context of Mauritius is linked up with human investment in education, economic growth, and income inequality. Empirical evidence shows that public-sector investment in education promotes economic growth, but at the expense of greater inequality of income. Among the vulnerable groups affected by this type of development process lies the fisherman community. In fact, children of poor families in coastal Mauritius have constrained access to complete school education because of the persistently high opportunity cost involved. Hence, this community is caught up in a vicious circle, as its children or grandchildren would barely be redeployed elsewhere other than in the fisheries sector itself. Such exclusion might account for the overexploitation of marine resources of the island and the accompanying reduction in fish catch over recent years.

  6. To make or buy patient safety solutions: a resource dependence and transaction cost economics perspective.

    Science.gov (United States)

    Fareed, Naleef; Mick, Stephen S

    2011-01-01

    For almost a decade, public and private organizations have pressured hospitals to improve their patient safety records. Since 2008, the Centers for Medicare & Medicaid Services has no longer been reimbursing hospitals for secondary diagnoses not reported during the point of admission. This ruling has motivated some hospitals to engage in safety-oriented programs to decrease adverse events. This study examined which hospitals may engage in patient safety solutions and whether they create these patient safety solutions within their structures or use suppliers in the market. We used a theoretical model that incorporates the key constructs of resource dependence theory and transaction cost economics theory to predict a hospital's reaction to Centers for Medicare & Medicaid Services "never event" regulations. We present propositions that speculate on how forces conceptualized from the resource dependence theory may affect adoption of patient safety innovations and, when they do, whether the adopting hospitals will do so internally or externally according to the transaction cost economics theory. On the basis of forces identified by the resource dependence theory, we predict that larger, teaching, safety net, horizontally integrated, highly interdependent, and public hospitals in concentrated, high public payer presence, competitive, and resource-rich environments will be more likely to engage in patient safety innovations. Following the logic of the transaction cost economics theory, we predict that of the hospitals that react positively to the never event regulation, most will internalize their innovations in patient safety solutions rather than approach the market, a choice that helps hospitals economize on transaction costs. This study helps hospital managers in their strategic thinking and planning in relation to current and future regulations related to patient safety. For researchers and policy analysts, our propositions provide the basis for empirical testing.

It summarizes research efforts performed at the National Renewable Energy Laboratory between 2015 and 2017 to analyze the resource potential, cost of offshore wind, and economic potential of offshore wind from four primary reports: Musial et al. (2016); Beiter et al. (2016, 2017); and Mone et al. (unpublished). From Musial et al. (2016), Maine's technical offshore wind resource potential ranked seventh in the nation overall with more than 411 terawatt-hours/year of offshore resource generating potential. Although 90% of this wind resource is greater than 9.0-meters-per-second average velocity, most of the resource is over deep water, where floating wind technology is needed. Levelized cost of energy and levelized avoided cost of energy were computed to estimate the unsubsidized 'economic potential' for Maine in the year 2027 (Beiter et al. 2016, 2017). The studies found that Maine may have 65 gigawatts of economic potential by 2027, the highest of any U.S. state. Bottom-line costs for the Aqua Ventus project, which is part of the U.S. Department of Energy's Advanced Technology Demonstration project, were released from a proprietary report written by NREL in 2016 for the University of Maine (Mone et al. unpublished). The report findings were that economies of scale and new technology advancements lowered the cost from $300/megawatt-hour (MWh) for the two-turbine 12-megawatt (MW) Aqua Ventus 1 project, to $126/MWh for the commercial-scale, 498-MW Aqua Ventus-2 project. Further cost reductions to $77/MWh were found when new technology advancements were applied for the 1,000-MW Aqua Ventus-3 project in 2030. No new analysis was conducted for this report.

    Climate change is a global problem with local climatic and economic impacts. Mitigation policies can be applied on large geographic scales, such as a carbon cap-and-trade program for the entire U.S., on medium geographic scales, such as the NOx program for the northeastern U.S., or on smaller scales, such as statewide renewable portfolio standards and local gasoline taxes. To enable study of the environmental benefits, transition costs, capitalization effects, and other consequences of mitigation policies, we are developing dynamic general equilibrium models capable of incorporating important climate impacts. This report describes the economic framework we have developed and the current Community Integrated Model of Economic and Resource Trajectories for Humankind (CIM-EARTH) instance.

    Full Text Available Global climate change, especially the phenomena of global warming, is expected to increase the intensity of land-falling hurricanes. Societal adaptation is needed to reduce vulnerability from increasingly intense hurricanes. This study quantifies the adaptation effects of potentially policy driven caps on housing densities and agricultural cover in coastal (and adjacent inland areas vulnerable to hurricane damages in the Atlantic and Gulf Coastal regions of the U.S. Time series regressions, especially Prais-Winston and Autoregressive Moving Average (ARMA models, are estimated to forecast the economic impacts of hurricanes of varying intensity, given that various patterns of land use emerge in the Atlantic and Gulf coastal states of the U.S. The Prais-Winston and ARMA models use observed time series data from 1900 to 2005 for inflation adjusted hurricane damages and socio-economic and land-use data in the coastal or inland regions where hurricanes caused those damages. The results from this study provide evidence that increases in housing density and agricultural cover cause significant rise in the de-trended inflation-adjusted damages. Further, higher intensity and frequency of land-falling hurricanes also significantly increase the economic damages. The evidence from this study implies that a medium to long term land use adaptation in the form of capping housing density and agricultural cover in the coastal (and adjacent inland states can significantly reduce economic damages from intense hurricanes. Future studies must compare the benefits of such land use adaptation policies against the costs of development controls implied in housing density caps and agricultural land cover reductions.

  14. Exhaustible resources and economic growth: the case of uranium mining in Saskatchewan

    1984-09-01

    This study examines the effect of a booming natural resource sector on regional economic growth, with particular attention to the impact of regional government policy on mineral rent taxation and the allocation of resource revenues. The author's approach is first to document the relevant theory and then to apply it to the case of the uranium industry in Saskatchewan. Governments often hold the view that a significant portion of resource rents flowing from the boom should be appropriated by the public sector. The usual arguments of efficiency and equity are explained, as is their applicability to uranium in Saskatchewan. The model is extended to include provincial tax and expenditure policies. Chapter 2 concentrates on mineral taxes and examines their various effects on the behaviour of firms with respect to exploration and extraction. The theory about the effects of mineral taxes on exploration and extraction is reviewed and is subsequently used to anticipate the effect of taxes on uranium mining. The Saskatchewan Uranium Royalty is explicitly considered in a quantitative model to analyse the effect on the rate of extraction on the Key Lake Mine. It is agreed that taxes collected by the Saskatchewan government are corrective in nature in that they lower the rate of extraction and make up for certain market failures and improve efficiency of resource use. It is not accepted, however, that the allocation of these taxes contributes to economic efficiency. Plentiful low cost uranium reserves are predicted but government policy is likely to limit rapid expansion. Weighing these factors and the world uranium market, uranium production forecasts are derived and an estimate is made of the impact of the industry on economic growth in Saskatchewan. The contribution to Gross Domestic Provincial Product in 2000 could be as high as 10% of the 1980 GDPP level and the contribution to employment as high as 9% of 1980 nonagricultural employment.

    Highlights: • We compare two remediation scenarios; one with resource recovery and one without. • Economic analysis includes relevant direct costs and revenues for the landfill owner. • High degrees of metal and/or combustible contents are important economic factors. • Landfill tax and the access to a CHP can have a large impact on the result. • Combining landfill mining and remediation may decrease the project cost. - Abstract: This article analyzes the economic potential of integrating material separation and resource recovery into a landfill remediation project, and discusses the result and the largest impact factors. The analysis is done using a direct costs/revenues approach and the stochastic uncertainties are handled using Monte Carlo simulation. Two remediation scenarios are applied to a hypothetical landfill. One scenario includes only remediation, while the second scenario adds resource recovery to the remediation project. Moreover, the second scenario is divided into two cases, case A and B. In case A, the landfill tax needs to be paid for re-deposited material and the landfill holder does not own a combined heat and power plant (CHP), which leads to disposal costs in the form of gate fees. In case B, the landfill tax is waived on the re-deposited material and the landfill holder owns its own CHP. Results show that the remediation project in the first scenario costs about €23/ton. Adding resource recovery as in case A worsens the result to −€36/ton, while for case B the result improves to −€14/ton. This shows the importance of landfill tax and the access to a CHP. Other important factors for the result are the material composition in the landfill, the efficiency of the separation technology used, and the price of the saleable material

    In order to get knowledge of the standard of water utilization of the Silk Road Economic Belt from international point of view, the paper analyzes the annual variation of water resources utilization in the Silk Road Economic Belt, and compares with other typical countries. The study shows that Water resources utilization efficiency has been greatly improved in recent 20 years and the water consumption per USD 10000 of GDP has been declined 87.97%. the improvement of industrial water consumption efficiency is the key driving factors for substantial decrease in water consumption.The comparison of water utilization and human development shows that the higher HDI the country is, the more efficient water utilization the country has. water consumption per USD 10000 of GDP in country with HDI>0.9 is 194m³, being 8.5% of that in country with HDI from 0.5 to 0.6. On the premise of maintaining the stable economic and social development of the Silk Road Economic Belt, the realization of the control target of total water consumption must depend on the strict control over the disorderly expansion of irrigated area, the change in the mode of economic growth, the implementation of the development strategy for new industrialization and urbanization, vigorous development of the processing industry with low water consumption as well as the high-tech and high value-added industry. Only in this way, the control target of total water consumption can be realized in the process of completing the industrialization task.

  18. An economic analysis of the electricity generation potential from biogas resources in the state of Indiana

    Science.gov (United States)

    Giraldo, Juan S.

    Anaerobic digestion is a process that is a common part of organic waste management systems and is used in concentrated animal feeding operations (CAFOs), wastewater treatment plants (WWTPs), and municipal solid waste (MSW) landfills. The process produces biogas, which contains methane, and it can be burned to generate electricity. Previous reports have indicated that based on the availability of feedstocks there is a large potential for biogas production and use for electricity generation in the state of Indiana. However, these reports varied in their consideration of important factors that affect the technical and economic feasibility of being able to develop the resources available. The goal of this thesis is to make a more targeted assessment of the electricity generation potential from biogas resources at CAFOs, WWTPs, and MSW landfills in Indiana. A capital budgeting model is used to estimate the net present value (NPV) of biogas electricity projects at facilities that are identified as technically suitable. A statewide estimate of the potential generation capacity is made by estimating the number of facilities that could profitably undertake a biogas electricity project. In addition this thesis explored the impact that different incentive policies would have on the economic viability of these projects. The results indicated that the electricity generation potential is much smaller when technical and economic factors are taken into account in addition to feedstock availability. In particular it was found that projects at hog farms are unlikely to be economically feasible in the present even when financial incentives are considered. In total, 47.94 MW of potential generating capacity is estimated from biogas production at CAFOs, WWTPs, and MSW landfills. Though results indicated that 37.10 MW of capacity are economically feasible under current operating conditions, sensitivity analysis reveals that these projects are very sensitive to capital cost assumptions

    An analysis of the amount and location of undiscovered mineral resources that are likely to be economically recoverable is important for assessing the long-term adequacy and availability of mineral supplies. This requires an economic evaluation of estimates of undiscovered resources generated by traditional resource assessments (Singer and Menzie, 2010). In this study, simplified engineering cost models were used to estimate the economic fraction of resources contained in undiscovered porphyry copper deposits, predicted in a global assessment of copper resources. The cost models of Camm (1991) were updated with a cost index to reflect increases in mining and milling costs since 1989. The updated cost models were used to perform an economic analysis of undiscovered resources estimated in porphyry copper deposits in six tracts located in North America. The assessment estimated undiscovered porphyry copper deposits within 1 kilometer of the land surface in three depth intervals.

    Full Text Available The advent of industrial economies coincides with the emergence of the economy as an autonomous discipline and with the question, not hitherto placed on the “value of nature”. As the basis of any theory of the first economists was the statement that every "value" is the work of man, was a fragile theoretical nature of the classics, since this is not the result of human labor. So, to circumvent the problem of fixing the "values​​" intrinsic to nature, environmental economics, in its most widespread version, part of the statement that assigns what is "value" is not exactly the environment or environmental resources but people's preferences in relation to changes in quality or quantity supplied of natural resource. The idea of ​​transaction rights on the environment (in fact, the right to pollute found resonance in the United States with "certified environmental" measures to better control pollution. They are traded for several polluting companies that can, in turn, trade them in the market for environmental permits. Remember that in any arrangement in which disputing parties settle in reaction conditions supposedly equal, makes a big difference the presence of those more able to lobby and power to influence public opinion. It is seen, even with the refinement that achieves economic analysis by incorporating as legitimate rights of non pollution, yet there is no guarantee the order of environmental damage if the whole issue be restricted to the context of the economic approach simply.

    In Victoria, Australia, most groundwater resources are now fully allocated and opportunities for new groundwater development can only occur through trading of license entitlements. Groundwater usage has rarely exceeded 50% of the available licensed volume, even in the 2008/9 drought year, and 50 to 70% of individual license holders use less than 5% of their allocation each year. However, little groundwater trading is occurring at present. Interviews were conducted with groundwater license holders and water brokers to investigate why the Victorian groundwater trade market is underdeveloped. Responses show there is a complex mix of social, economic, institutional and technical reasons. Barriers to trade are influenced by the circumstances of each groundwater user, administrative process and resource management rules. Water brokers deal with few trades at low margins and noted unrealistic selling prices and administrative difficulties. Irrigators who have successfully traded identify that there are few participants in trading, technical appraisals are expensive and administrative requirements and fees are burdensome, especially when compared to surface water trading. Opportunities to facilitate trade include groundwater management plan refinement and improved information provision. Simplifying transaction processes and costs, demonstrating good resource stewardship and preventing third party impacts from trade could address some concerns raised by market participants. There are, however, numerous individual circumstances that inhibit groundwater trading, so it is unlikely that policy and process changes alone could increase usage rates without greater demand for groundwater or more favourable farming economic circumstances.

    Resource allocation to multiple alternative conservation actions is a complex task. A common trade-off occurs between protection of smaller, expensive, high-quality areas versus larger, cheaper, partially degraded areas. We investigate optimal allocation into three actions in boreal forest: current standard forest management rules, setting aside of mature stands, or setting aside of clear-cuts. We first estimated how habitat availability for focal indicator species and economic returns from timber harvesting develop through time as a function of forest type and action chosen. We then developed an optimal resource allocation by accounting for budget size and habitat availability of indicator species in different forest types. We also accounted for the perspective adopted towards sustainability, modeled via temporal preference and economic and ecological time discounting. Controversially, we found that in boreal forest set-aside followed by protection of clear-cuts can become a winning cost-effective strategy when accounting for habitat requirements of multiple species, long planning horizon, and limited budget. It is particularly effective when adopting a long-term sustainability perspective, and accounting for present revenues from timber harvesting. The present analysis assesses the cost-effective conditions to allocate resources into an inexpensive conservation strategy that nevertheless has potential to produce high ecological values in the future.

    2011-05-01

    Full Text Available Abstract Background The aim of this study is to develop, apply and evaluate an economics-based framework to assist commissioners in their management of finite resources for local dental services. In April 2006, Primary Care Trusts in England were charged with managing finite dental budgets for the first time, yet several independent reports have since criticised the variability in commissioning skills within these organisations. The study will explore the views of stakeholders (dentists, patients and commissioners regarding priority setting and the criteria used for decision-making and resource allocation. Two inter-related case studies will explore the dental commissioning and resource allocation processes through the application of a pragmatic economics-based framework known as Programme Budgeting and Marginal Analysis. Methods/Design The study will adopt an action research approach. Qualitative methods including semi-structured interviews, focus groups, field notes and document analysis will record the views of participants and their involvement in the research process. The first case study will be based within a Primary Care Trust where mixed methods will record the views of dentists, patients and dental commissioners on issues, priorities and processes associated with managing local dental services. A Programme Budgeting and Marginal Analysis framework will be applied to determine the potential value of economic principles to the decision-making process. A further case study will be conducted in a secondary care dental teaching hospital using the same approach. Qualitative data will be analysed using thematic analysis and managed using a framework approach. Discussion The recent announcement by government regarding the proposed abolition of Primary Care Trusts may pose challenges for the research team regarding their engagement with the research study. However, whichever commissioning organisations are responsible for resource allocation

    Water resources is vital in social and economic activities. Total global water use is increasing, mainly due to economic and population growth in developing countries. It has one of risk with high agreement and robust evidence that freshwater-related risks of climate change increase significantly with increasing greenhouse gas concentrations. It is difficult to compare the risk with other field risk (e.g. agriculture, forestry, sea level rise) for considering both adaptation and mitigation policy with the level of decision makers and public servants. Economic impacts of climate change on water scarcity has been estimated by economic researchers. We have no certainty at all about integration between hydrological and economical fields on global scale. In this study, we highlight key concerns about conventional estimations of economic impact on water resources through meta-analysis. The economic impact on water resource in same base year using consumer price index is shown with increase in the global mean temperature. We clarified four concerns which are involved in 1) classification of economic mechanism, 2) estimated items of economic impact, 3) difference in estimating equations, and 4) definition of parameters related with economic impact of climate change. This study would be essential to next challenge as transdisciplinary research between hydrologic and economic fields.

    Full Text Available The research is focused on efficiency assessment of economic cooperation in development of Arctic offshore oil and gas resources. The author developed an economic model based on cost-benefit analysis (CBA. CBA is used in some countries (EU, USA, Australia as an analytic tool to make public policy decisions. CBA is based on the method of discounting cash flows associated with costs and benefits of public policy. It is assumed that all public goals are equally important inter alia, hence public bodies should opt for those initiatives that maximize public benefits for every dollar spent from the state budget. There are five stages of economic modeling: 1 the definition of public benefits and costs associated with the public initiative; 2 monetary valuation of costs and benefits; 3 the definition of discounting period and discounting rate; 4 the calculation of net present value of cash flows; 5 the comparison of initiatives' net present values. The model is built with a number of hypotheses assumed. It allows making evaluation of investments into the technology to decrease the cost of Arctic offshore oil and gas development. Moreover, the model has two scenarios describing a public policy to support technology development with international economic cooperation and without it. Under given hypotheses both scenarios return positive net present value of policies which proves that governmental initiative to support Arctic technology development is economically justified. Also the model sows that the scenario with international cooperation is more efficient from economic point of view. It is explained by two factors: the higher speed of technology transfer (due W international cooperation and the opportunity to use financial leverage (attracting the funds from foreign partners. The model allows closing the existing scientific gap between the theory of CBA method and its practical use in public decision making.

    Full Text Available This qualitative research investigates interpretive schemata by producers for automotive industry during the economic crisis in Slovenia. Specifically, the interest was in their Human resource management (HRM schemata in current crisis. We explained the dynamics of schema change on the basis of Piaget's theory of adaptation. In-depth interviews with CEOs, directors of HRM and leaders of trade unions served as a primary data source. In addition, comparative analysis of social responsibility as reported in companies' annual reports in 2007 and 2008 was made. Firstly, results demonstrate strategic role of HRM in chosen companies. Secondly, present economic crisis does not serve as a factor of schema change. In conclusion, participants mostly assimilate new information from environment to fit their HRM schemata. Results show the major factor for both assimilation and lack of schema change is occurrence of crisis in Slovenian companies that produce for automotive industry in the nineties.

    Baumeister, Roy F; Vohs, Kathleen D

    2004-01-01

    A heterosexual community can be analyzed as a marketplace in which men seek to acquire sex from women by offering other resources in exchange. Societies will therefore define gender roles as if women are sellers and men buyers of sex. Societies will endow female sexuality, but not male sexuality, with value (as in virginity, fidelity, chastity). The sexual activities of different couples are loosely interrelated by a marketplace, instead of being fully separate or private, and each couple's decisions may be influenced by market conditions. Economic principles suggest that the price of sex will depend on supply and demand, competition among sellers, variations in product, collusion among sellers, and other factors. Research findings show gender asymmetries (reflecting the complementary economic roles) in prostitution, courtship, infidelity and divorce, female competition, the sexual revolution and changing norms, unequal status between partners, cultural suppression of female sexuality, abusive relationships, rape, and sexual attitudes.

    2015-01-01

    Since the 1990's, Vietnam has been mutating into an economic dragon together with an unprecedented demographic boom. The high growth expresses itself through an increased demand for energy and raw materials. Though Vietnam is endowed with quite a number of resources, most of them are available in limited amounts. Medium-term estimates reckon the country's fossil resources will not meet the domestic demand. Consequently, Hanoi is planning the development of a national energy policy focused on three sectors: hydroelectricity, renewable energies, and civilian nuclear programme. For lack of strict work plans and adequate financing, the Vietnam energy development plan does not sound technically and financially feasible without the help of foreign players whose presence on the national territory exacerbates the local, national and regional geopolitical stakes

  12. Integrating Demand-Side Resources into the Electric Grid: Economic and Environmental Considerations

    Science.gov (United States)

    Fisher, Michael J.

    Demand-side resources are taking an increasingly prominent role in providing essential grid services once provided by thermal power plants. This thesis considers the economic feasibility and environmental effects of integrating demand-side resources into the electric grid with consideration given to the diversity of market and environmental conditions that can affect their behavior. Chapter 2 explores the private economics and system-level carbon dioxide reduction when using demand response for spinning reserve. Steady end uses like lighting are more than twice as profitable as seasonal end uses because spinning reserve is needed year-round. Avoided carbon emission damages from using demand response instead of fossil fuel generation for spinning reserve are sufficient to justify incentives for demand response resources. Chapter 3 quantifies the system-level net emissions rate and private economics of behind-the-meter energy storage. Net emission rates are lower than marginal emission rates for power plants and in-line with estimates of net emission rates from grid-level storage. The economics are favorable for many buildings in regions with high demand charges like California and New York, even without subsidies. Future penetration into regions with average charges like Pennsylvania will depend greatly on installation cost reductions and wholesale prices for ancillary services. Chapter 4 outlines a novel econometric model to quantify potential revenues from energy storage that reduces demand charges. The model is based on a novel predictive metric that is derived from the building's load profile. Normalized revenue estimates are independent of the power capacity of the battery holding other performance characteristics equal, which can be used to calculate the profit-maximizing storage size. Chapter 5 analyzes the economic feasibility of flow batteries in the commercial and industrial market. Flow batteries at a 4-hour duration must be less expensive on a dollar per

In a time of market, policy, and climate transformations, economic analyses are critical to help policy-makers and resource managers make appropriate decisions. At the 2016 Meeting of the International Society of Forest Resource Economics (...

    Long term management of water resources is challenging for decision makers given the range of uncertainties that exist. Such uncertainties are a function of long term drivers of change, such as climate, environmental loadings, demography, land use and other socio economic drivers. Impacts of climate change on frequency of extreme events such as drought make it a serious threat to water resources and water security. The release of probabilistic climate information, such as the UKCP09 scenarios, provides improved understanding of some uncertainties in climate models. This has motivated a more rigorous approach to dealing with other uncertainties in order to understand the sensitivity of investment decisions to future uncertainty and identify adaptation options that are as far as possible robust. We have developed and coupled a system of models that includes a weather generator, simulations of catchment hydrology, demand for water and the water resource system. This integrated model has been applied in the Thames catchment which supplies the city of London, UK. This region is one of the driest in the UK and hence sensitive to water availability. In addition, it is one of the fastest growing parts of the UK and plays an important economic role. Key uncertainties in long term water resources in the Thames catchment, many of which result from earth system processes, are identified and quantified. The implications of these uncertainties are explored using a combination of uncertainty analysis and sensitivity testing. The analysis shows considerable uncertainty in future rainfall, river flow and consequently water resource. For example, results indicate that by the 2050s, low flow (Q95) in the Thames catchment will range from -44 to +9% compared with the control scenario (1970s). Consequently, by the 2050s the average number of drought days are expected to increase 4-6 times relative to the 1970s. Uncertainties associated with urban growth increase these risks further

  15. Economic principles for resource allocation decisions at national level to mitigate the effects of disease in farm animal populations.

    This paper originated in a project to develop a practical, generic tool for the economic evaluation of surveillance for farm animal diseases at national level by a state veterinary service. Fundamental to that process is integration of epidemiological and economic perspectives. Using a generalized example of epidemic disease, we show that an epidemic curve maps into its economic equivalent, a disease mitigation function, that traces the relationship between value losses avoided and mitigation resources expended. Crucially, elementary economic principles show that mitigation, defined as loss reduction achieved by surveillance and intervention, must be explicitly conceptualized as a three-variable process, and the relative contributions of surveillance and intervention resources investigated with regard to the substitution possibilities between them. Modelling the resultant mitigation surfaces for different diseases should become a standard approach to animal health policy analysis for economic efficiency, a contribution to the evolving agenda for animal health economics research.

  16. The water-energy-food-climate-economics nexus: solving hunger and resource scarcity

    A nexus refers to the core or to interconnectivity across issues. Addressing the boundary interactions of traditional sectors in an interconnected world as human activities change the physical boundaries of land and climate is an emerging academic and governance discourse. Through contrasting examples from the US and India, I shed light on the descriptive aspects of these connections and feedbacks that define potential impacts or traps for societies, and ponder whether a massive conceptual or numerical Earth System Model can help inform outcomes, or whether there are dominant links at particular scales (physical, social, economic or biological) that characterize the emergent dynamics and define critical equilibrium or transient solutions in certain places. However, the real question is what next given the definition of the nexus? Here, I argue that given the current valuation and management structure of different resource sectors and the associated information flows and sensitivities, the interlinked energy-climate issues can emerge as useful drivers of improved productivity in water-food systems, thus promoting resource and environmental sustainability while promoting economic development. Thus, levers can be found that help steer the course of these complex interacting systems towards desirable sectoral outcomes.

    To investigate how participants in an economic resource allocation survey construct notions of fairness. Qualitative interview study guided by interpretive grounded theory methods. Qualitative interviews were conducted with volunteer university- (n=39) and community-based (n =7) economic survey participants. INTERVENTION OR MAIN VARIABLES STUDIED: We explored how participants constructed meanings to guide or explain fair survey choices, focusing on rationales, imagery and additional desired information not provided in the survey scenarios. Data were transcribed and coded into qualitative categories. Analysis iterated with data collection iterated through three waves of interviews. Participants compared the survey dilemmas to domains outside the health system. Most compared them with other micro-level, inter-personal sharing tasks. Participants raised several fairness-relevant factors beyond need or capacity to benefit. These included age, weight, poverty, access to other options and personal responsibility for illness; illness duration, curability or seriousness; life expectancy; possibilities for sharing; awareness of other's needs; and ability to explain allocations to those affected. They also articulated a fairness principle little considered by equity theories: that everybody must get something and nobody should get nothing. Lay criteria for judging fairness are myriad. Simple scenarios may be used to investigate lay commitments to abstract principles. Although principles are the focus of analysis and inference, participants may solve simplified dilemmas by imputing extraneous features to the problem or applying unanticipated principles. These possibilities should be taken into account in the design of resource allocation surveys eliciting the views of the public. © 2012 John Wiley & Sons Ltd.

  19. The future of India's economic growth: the natural resources and energy dimension

    Energy Technology Data Exchange (ETDEWEB)

    2004-09-01

    The continuation of widespread poverty apart, the biggest danger that India faces is the wanton destruction and degradation of all the country's natural resources and a growing, unsustainable, dependence on the use of hydrocarbon fuels. We are losing ten percent of our GDP as a result of the damage to and degradation of our natural resources. But environmental decision-making has not yet been merged with mainstream economic decision making. In the developed countries, environmental protection followed a path defined by the Environmental Kuznets curve, involving significant increases in income and pollution levels to a point where the trend changed. A developing country like India cannot pursue the same path, and would need to set up a governance structure and policy regime that allow the turning point to take place at substantially lower levels of income. The internalization of social and environmental externalities would ensure that resources are used in a sustainable and responsible manner. In the matter of energy use, for instance, proactive policies - such as stress on renewable sources and the rationalisation of subsidies - are needed to decrease the dependence on unsustainable imports and to create the conditions under which the dispossessed and poor sections of society are able to meet their basic energy needs. Blindly aping the consumerist approach of the developed world, and neglecting the ecological footprint of lifestyles, could prove disastrous for our populous country. (author)

  20. A bio-economic application to the Cape Rock Lobster resource using a delay difference modelling approach

    2004-06-01

    Full Text Available In many species, like the Cape Rock Lobster (Jasus lalandii, the life cycles of males and females differ. This may motivate the use of two-sex models in a stock-assessment analysis. It is also true for this resource, that juveniles do not reach sexual maturity immediately. Therefore a delay-difference model is appropriate. In this study we follow a bio-economic approach and use a two-sex delay-difference model to determine a maximum economic yield strategy. Thus we determine an economic optimum steady state solution at which to harvest this resource subject to the biological constraints of the species.

    The one-dimensional fall of a folded chain with one end suspended from a rigid support and a chain falling from a resting heap on a table is studied. Because their Lagrangians contain no explicit time dependence, the falling chains are conservative systems. Their equations of motion are shown to contain a term that enforces energy conservation when masses are transferred between subchains. We show that Cayley's 1857 energy nonconserving solution for a chain falling from a resting heap is inco...

  2. County-Level Population Economic Status and Medicare Imaging Resource Consumption.

    2017-06-01

    The aim of this study was to assess relationships between county-level variation in Medicare beneficiary imaging resource consumption and measures of population economic status. The 2013 CMS Geographic Variation Public Use File was used to identify county-level per capita Medicare fee-for-service imaging utilization and nationally standardized costs to the Medicare program. The County Health Rankings public data set was used to identify county-level measures of population economic status. Regional variation was assessed, and multivariate regressions were performed. Imaging events per 1,000 Medicare beneficiaries varied 1.8-fold (range, 2,723-4,843) at the state level and 5.3-fold (range, 1,228-6,455) at the county level. Per capita nationally standardized imaging costs to Medicare varied 4.2-fold (range, $84-$353) at the state level and 14.1-fold (range, $33-$471) at the county level. Within individual states, county-level utilization varied on average 2.0-fold (range, 1.1- to 3.1-fold), and costs varied 2.8-fold (range, 1.1- to 6.4-fold). For both large urban populations and small rural states, Medicare imaging resource consumption was heterogeneously variable at the county level. Adjusting for county-level gender, ethnicity, rural status, and population density, countywide unemployment rates showed strong independent positive associations with Medicare imaging events (β = 26.96) and costs (β = 4.37), whereas uninsured rates showed strong independent positive associations with Medicare imaging costs (β = 2.68). Medicare imaging utilization and costs both vary far more at the county than at the state level. Unfavorable measures of county-level population economic status in the non-Medicare population are independently associated with greater Medicare imaging resource consumption. Future efforts to optimize Medicare imaging use should consider the influence of local indigenous socioeconomic factors outside the scope of traditional beneficiary-focused policy

    Economic peculiarity of Russian resource-oriented territories are based on a focal type of industrial complex, differentiation of economies within a principle of mining and processing of natural resources. To improve the economic condition and integrate into the world innovative process is essential to solve the problem of eliminating the prevalence of resourse focus in the industrial economic structure that could ensure the overcoming of the existing spa- cial dissociation and market mechanisms development in innovative promotion. The monitoring system, involving the integral indicator of socioeconomic and territorial potential assessment, has suggested by the authors. The integral indicator could guarantee the objective evaluation of economic condition within a territory that is vital for the governmental authorities to design strategies providing the economic development of administrative territories.

    Full Text Available This paper examines the impact of two main alliance motivation theories, transaction cost economics (TCE and resource based view (RBV, on alliance processes among Korean manufacturing high-tech ventures. Results show that TCE and RBV are complimentarily explaining the formation of inter-firm alliances. TCE variables are more related with alliance partner characteristics while RBV is more linked with partner capabilities. Both show positive effects on performance. No significant effect is found on determining an alliance governance structure. While selecting appropriate technological alliance partners show positive effects on performance, no significant effect is found between alliance governance structure and performance. Factors of both theories impacting each alliance stage and analytical explanations of such impacts are discussed.

    2010-06-01

    Full Text Available This article focuses, from a theological perspective, on both the ecological crisis and the politico-economic dealings in relation to water – especially with regard to the unsound ways in which governments deal with this resource. Texts are read from an anthropogenic perspective, as opposed to an anthropocentric one. Such a reading scenario calls for responses from theology with regard to the human position in creation. Humans are not a grand master plan of creation, but the completion and fulfilment of it, given an enormous sense of responsibility for the earth. The article argues that the human–earth relation should be understood from the point of responsibility based on solidarity, interdependency and stewardship. Theologians are challenged to embrace eco-ethics.

    We present unit costs corresponding to resource information collected in the Schizophrenia Outpatient Health Outcomes (SOHO) Study. The SOHO study is a 3-year, prospective, observational study of health outcomes associated with antipsychotic treatment in out-patients treated for schizophrenia. The study is being conducted across 10 European countries (Denmark, France, Germany, Greece, Ireland, Italy, the Netherlands, Portugal, Spain and the UK) and includes over 10,800 patients and over 1000 investigators. To identify the best available unit costs of hospital admissions, day care and psychiatrist out-patient visits, a tariff-based approach was used. Unit costs were obtained for nine of the 10 countries and were adjusted to 2000 price levels by consumer price indices and converted to US dollars using purchasing power parity rates (and on to Euro). The paper illustrates the need to balance the search for sound unit costs with pragmatic solutions in the costing of international economic evaluations.

    2016-01-01

    The aim of this work is to analyze the spatial distribution of potential pollution pathways of water resources given the economic activity in the Mexican border state of Sonora and propose a regional distribution in relation to cancer mortality rates across the state. The methodology is based in an exploratory and inferential data analysis using two sources of primary data: wastewater discharge concessions registered in the Public Registry on Water Rights [Registro Público de Derechos de Agua] (REPDA) and the records generated by the National Health Information System [Sistema Nacional de Información en Salud] (SINAIS) in the period 1998-2011 based on the International Classification of Disease (ICD-10). The spatial concentration analysis allows for the identification of specific cancer mortality causes at the regional level. Results indicate that the projected adjustments to the regulation NOM-250-SSA1-2014, which controls a subset of pollutants common in mining activity surroundings, is a matter of regional concern.

    detailed analysis of the most suitable types of industries and the costs is required, allowing a targeted exploitation of this resource. This work extends the spatial and thermodynamic analysis, to account for the temporal match between industrial excess heat and district heating demands, as well...... as the costs for implementation and operation of the systems. This allows the determination of cost-effective district heating potentials, as well as the analysis of different industries and technological requirements. The results show that the temporal mismatch between excess heat and district heating demand...... and lack of demand, reduces the theoretical substitution potential by almost 30%. If heat storages are introduced, the total potential is reduced by only 10%. A majority of the excess heat can be utilised at socio-economic heating costs lower than the average Danish district heating price and the cost...

  10. On the global economic potentials and marginal costs of non-renewable resources and the price of energy commodities

    Mercure, Jean-François; Salas, Pablo

    2013-01-01

    A model is presented in this work for simulating endogenously the evolution of the marginal costs of production of energy carriers from non-renewable resources, their consumption, depletion pathways and timescales. Such marginal costs can be used to simulate the long term average price formation of energy commodities. Drawing on previous work where a global database of energy resource economic potentials was constructed, this work uses cost distributions of non-renewable resources in order to evaluate global flows of energy commodities. A mathematical framework is given to calculate endogenous flows of energy resources given an exogenous commodity price path. This framework can be used in reverse in order to calculate an endogenous marginal cost of production of energy carriers given an exogenous carrier demand. Using rigid price inelastic assumptions independent of the economy, these two approaches generate limiting scenarios that depict extreme use of natural resources. This is useful to characterise the current state and possible uses of remaining non-renewable resources such as fossil fuels and natural uranium. The theory is however designed for use within economic or technology models that allow technology substitutions. In this work, it is implemented in the global power sector model FTT:Power. Policy implications are given. - Highlights: • Theoretical model to forecast marginal costs of non-renewable resources. • Tracks the consumption and costs of non-renewable resources. • For use in economic or technology models

    2004-01-14

    Grant Number DE-FG02-98ER62665 Office of Energy Research of the U.S. Department of Energy Abstract Many Integrated Assessment Models (IAM) divide the world into a small number of highly aggregated regions. Non-OECD countries are aggregated geographically into continental and multiple-continental regions or economically by development level. Current research suggests that these large scale aggregations cannot accurately represent potential water resources-related climate change impacts. In addition, IAMs do not explicitly model the flow regulation impacts of reservoir and ground water systems, the economics of water supply, or the demand for water in economic activities. Using the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) model of the International Food Policy Research Institute (IFPRI) as a case study, this research implemented a set of methodologies to provide accurate representation of water resource climate change impacts in Integrated Assessment Models. There were also detailed examinations of key issues related to aggregated modeling including: modeling water consumption versus water withdrawals; ground and surface water interactions; development of reservoir cost curves; modeling of surface areas of aggregated reservoirs for estimating evaporation losses; and evaluating the importance of spatial scale in river basin modeling. The major findings include: - Continental or national or even large scale river basin aggregation of water supplies and demands do not accurately capture the impacts of climate change in the water and agricultural sector in IAMs. - Fortunately, there now exist gridden approaches (0.5 X 0.5 degrees) to model streamflows in a global analysis. The gridded approach to hydrologic modeling allows flexibility in aligning basin boundaries with national boundaries. This combined with GIS tools, high speed computers, and the growing availability of socio-economic gridded data bases allows assignment of

    This paper reports on our effort to develop an ensemble of specialized models to explore the commercial potential of mining water/ice on Mars in support of a Mars Colony. This ensemble starts with a formal systems architecting framework to describe a Mars Colony and capture its artifacts' parameters and technical attributes. The resulting database is then linked to a variety of ;downstream; analytic models. In particular, we integrated an extraction process (i.e., ;mining;) model, a simulation of the colony's environmental control and life support infrastructure known as HabNet, and a risk-based economics model. The mining model focuses on the technologies associated with in situ resource extraction, processing, storage and handling, and delivery. This model computes the production rate as a function of the systems' technical parameters and the local Mars environment. HabNet simulates the fundamental sustainability relationships associated with establishing and maintaining the colony's population. The economics model brings together market information, investment and operating costs, along with measures of market uncertainty and Monte Carlo techniques, with the objective of determining the profitability of commercial water/ice in situ mining operations. All told, over 50 market and technical parameters can be varied in order to address ;what-if; questions, including colony location.

    Collins, Alan R.; Hansen, Evan; Hendryx, Michael

    2012-01-01

    Two energy development scenarios were compared for the Coal River Mountain in Raleigh County, West Virginia: (1) mountaintop mining (MTM) of coal, and (2) wind energy plus underground mining of coal. Economic impact computations over the life of each energy development scenario were made on a county basis for output of goods and services, the number of jobs created, and local earnings. Externality costs were assigned monetary values for coal mining and subtracted from earnings. Premature mortality within the general population due to additional coal mining accounted for 96% of these external cost computations. The results showed that economic output over the life of each scenario was twice as high for MTM mining as wind energy plus underground coal mining. Over the short term, employment and earnings were higher for MTM mining, but towards the end of the scenario, cumulative employment and earnings became higher under scenario (2). When local externality costs were subtracted from local earnings, MTM coal production had an overall negative net social impact on the citizens of Raleigh County. The external costs of MTM coal production provide an explanation of the existence of a “resource curse” and the conflicting results of output versus income provide insights into why coal-producing counties are underdeveloped. - Highlights: ► Mountaintop mining (MTM) was compared to wind plus underground mining. ► Economic output was twice as high for MTM. ► Employment and earnings were cumulatively higher for wind energy. ► Including local externality costs, MTM had an overall negative net social impact. ► Results provide insights into why coal-producing counties are underdeveloped.

    Full Text Available The state of fisheries has been researched based on a systematic approach and comprehensive analysis of statistical data, the following issues have been characterized: the catch of aquatic biological resources (ABR, consumption of fish products, problems in the development of the fishing industry (fleet aging, lack of innovative technologies, the proliferation of IUU fishing4 , the high level of retail prices for fish, low degree of processing export products, overshoot "improper objects" of fishing, the gap in aquaculture development, low economic efficiency. To improve the quality of fishery management it has been proposed to form the organizational and economic mechanism of ABR rational use, which should include effective tools for the implementation of management decisions. Instead of the so-called "historical" principle it has been suggested to use the investment principle of quota allocation and rental payments. The basis for management of fishing industry should be scientifically based on the bioeconomic concept of ABR rational use, the essence of which is to preserve the ABR and at the same time to obtain the maximum output of finished products with high added value. To form the organizational and economic mechanism it is necessary to develop a programme of innovative development of the fisheries sector, a calendar programme of upgrading of fishing fleet, wellreasoned differential rates of rent payments for the ABR use, scenarios and graphic organization of work of fishing vessels in specific fishing areas, to form regional financial and industrial clusters, to expand the authority of the Fisheries Agency, to improve corporate social responsibility of the fishing business communities. Modernization of management system for ABR rational use can significantly reduce environmental pollution, ensure the effective delivery of catch to shore, their high-quality processing and the needs of the population in fish products.

    Full Text Available Background: An ageing population, a growing prevalence of chronic diseases and limited financial resources for health care underpin the importance of prevention of disabling health disorders and care dependency in the elderly. A wide variety of measures is generally available for the prevention of falls and fall-related injuries. The spectrum ranges from diagnostic procedures for identifying individuals at risk of falling to complex interventions for the removal or reduction of identified risk factors. However, the clinical and economic effectiveness of the majority of recommended strategies for fall prevention is unclear. Against this background, the literature analyses in this HTA report aim to support decision-making for effective and efficient fall prevention.Research questions: The pivotal research question addresses the effectiveness of single interventions and complex programmes for the prevention of falls and fall-related injuries. The target population are the elderly (> 60 years, living in their own housing or in long term care facilities. Further research questions refer to the cost-effectiveness of fall prevention measures, and their ethical, social and legal implications. Methods: Systematic literature searches were performed in 31 databases covering the publication period from January 2003 to January 2010. While the effectiveness of interventions is solely assessed on the basis of randomised controlled trials (RCT, the assessment of the effectiveness of diagnostic procedures also considers prospective accuracy studies. In order to clarify social, ethical and legal aspects all studies deemed relevant with regard to content were taken into consideration, irrespective of their study design. Study selection and critical appraisal were conducted by two independent assessors. Due to clinical heterogeneity of the studies no meta-analyses were performed.Results: Out of 12,000 references retrieved by literature searches, 184 meet the

    NIPER was contracted by the US Department of Energy Bartlesville (Okla.) Project Office (DOE/BPO) to identify research needs to increase production of the domestic oil resource, and K ampersand A Energy Consultants, Inc. was subcontracted to review EOR field projects. This report summarizes the findings of that investigation. Professional society and trade journals, DOE reports, dissertations, and patent literature were reviewed to determine the state-of-the-art of enhanced oil recovery (EOR) and drilling technologies and the constraints to wider application of these technologies. The impacts of EOR on the environment and the constraints to the application of EOR due to environmental regulations were also reviewed. A review of well documented EOR field projects showed that in addition to the technical constraints, management factors also contributed to the lower-than-predicted oil recovery in some of the projects reviewed. DOE-sponsored projects were reviewed, and the achievements by these projects and the constraints which these projects were designed to overcome were also identified. Methods of technology transfer utilized by the DOE were reviewed, and several recommendations for future technology transfer were made.

A review of well documented EOR field projects showed that in addition to the technical constraints, management factors also contributed to the lower-than-predicted oil recovery in some of the projects reviewed. DOE-sponsored projects were reviewed, and the achievements by these projects and the constraints which these projects were designed to overcome were also identified. Methods of technology transfer utilized by the DOE were reviewed, and several recommendations for future technology transfer were made. Finally, several research areas were identified and recommended to maximize economic producibility of the domestic oil resource. 14 figs., 41 tabs.

  19. Feasibility study : identifying economic opportunities for bugwood and other biomass resources in Alberta and BC

    International Nuclear Information System (INIS)

    2008-04-01

    This feasibility study discussed energy technologies for biomass feedstocks including mill residues, roadside residues, and non-merchantable tree stands in Alberta and British Columbia (BC). The study demonstrated that the lack of mill residue resources means that targeted government support may be needed to help the energy industry to use more costly resources such as roadside residue or bugwood. Government policies are also needed to support the long-term availability of biomass supplies in order to lower the supply risks related to the use of biomass resources in the energy industry. Lower prices for power in both provinces make the use of biomass unfavourable for small-scale technologies under 10 MW. However, cogeneration projects using biomass showed higher returns when power conversion efficiency was low. Higher revenues were generated from heat sales displacing natural gas than from electricity sales at current tariffs. Large-scale biomass power plants were viable when lower-cost feedstocks were available. Bio-oils were suitable as supplements for heat generation in cogeneration processes. Pellet production was also viable using less expensive feedstocks.The co-firing of biomass at coal plants required little capital investment. The study demonstrated that Alberta's power production incentive of $60 per MWh was sufficient to improve the economics of small-scale projects. It was recommended that the program be continued and paid out over a period of 10 years. It was concluded that specific electricity tariffs and incentives are needed to accelerate regrowth and create a viable biomass industry for the future. 33 refs., 45 tabs., 17 figs

    There is growing demand for economic analysis to support strategic decision-making for mental health but the availability of economic evidence, in particular on system performance remains limited. The Mental Health Economics European Network (MHEEN) was set up in 2002 with the broad objective of developing a base for mental health economics information and subsequent work in 17 countries. Data on financing, expenditure and costs, provision of services, workforce, employment and capacity for economic evaluation were collected through bespoke questionnaires developed iteratively by the Network. This was augmented by a literature review and analysis of international databases. Findings on financing alone suggest that in many European countries mental health appears to be neglected while mechanisms for resource allocation are rarely linked to objective measure of population mental health needs. Numerous economic barriers and potential solutions were identified. Economic incentives may be one way of promoting change, although there is no 'one size fits all solution. There are significant benefits and synergies to be gained from the continuing development of networks such as MHEEN. In particular the analysis can be used to inform developments in Central and Eastern Europe. For instance there is much that can be learnt on both how the balance of care between institutional and non-institutional care has changed and on the role played by economic incentives in ensuring that resources were used to develop alternative community-based systems.

    The paper reports the results of a simple cointegration analysis applied to bivariate causality models using data on resource output, oil prices, terms of trade, current account and output growth to investigate the long-term relationships among these major macroeconomic aggregates in a resource-related economic model of Australia. For the period 1960-1990, the empirical evidence indicates that these five macro-variables, as formulated in our model, are not random walks. In addition, resource production and oil prices are significantly cointegrated, and they are also significantly cointegrated with the current account, terms of trade and economic growth. These findings provide support to the long-term adjustments foundation of our resource-related model. (author)

    The first U.S. Department of the Interior Economics Workshop was held April 5–7, 2017 in Washington, D.C., to identify, highlight, and better understand needs and opportunities for economic analysis to support the Department of the Interior’s mission. The Economics Workshop, jointly convened by the Department of the Interior Office of Policy Analysis and the U.S. Geological Survey Science and Decisions Center, provided an opportunity for Department of the Interior’s economists to share expertise and experiences and to build collaboration and communication channels across the Department of the Interior.Natural and cultural resource managers face complex questions and often have to balance competing stakeholder interests. Per the mission statement, the Department of the Interior “protects and manages the Nation’s natural resources and cultural heritage; provides scientific and other information about those resources; and honors its trust responsibilities or special commitments to American Indians, Alaska Natives, and affiliated island communities.” Economic analysis is relevant to issues integral to nearly all the land and water management decisions made by the Department of the Interior. More than 80 Department of the Interior economists gathered at the Economics Workshop to share their work, discuss common challenges, and identify approaches to advance the use and contribution of economics at the Department of the Interior.

    As Greenland is very dependent on imported articles and fuels, mainly petroleum, economic crisis or just an energy crisis will affect Greenland very much. To evaluate Greenlands situation in a crisis an account is given of the climatic conditions, of the present economic situation, and of planned development projects, The Greenland Area has Denmarks largest potential energy reserves of known coal deposits, of partially surveyed uranium deposits, of partially surveyed potential hydroelectric power reserves, and of petroleum and natural gas deposits not yet pointed out. An analysis is made of the utilization of the Greenland energy resources today, and the plans of future extended utilization. (LN)

  4. Economic Insights into Providing Access to Improved Groundwater Sources in Remote, Low-Resource Areas

    Groundwater is often the most or only feasible drinking water source in remote, low-resource areas. Yet the economics of its development have not been systematically outlined. We applied CBARWI (Cost-Benefit Analysis for Remote Water Improvements), a recently developed Decision Support System, to investigate the economic, physical and management factors related to the costs and benefits of non-networked groundwater supply in remote areas. Synthetic profiles of community water services (n = 17,962), defined across 14 parameters' values and ranges relevant to remote areas, were imputed into the decision framework, and the parameter effects on economic outcomes were investigated through regression analysis (Table 1). Several approaches were included for financing the improvements, after Abramson et al, 2011: willingness-to -pay (WTP), -borrow (WTB) and -work (WTW) in community irrigation (';water-for-work'). We found that low-cost groundwater development approaches are almost 7 times more cost-effective than conventional boreholes fitted with handpumps. The costs of electric, submersible borehole pumps are comparable only when providing expanded water supplies, and off-grid communities pay significantly more for such expansions. In our model, new source construction is less cost-effective than improvement of existing wells, but necessary for expanding access to isolated households. The financing approach significantly impacts the feasibility of demand-driven cost recovery; in our investigation, benefit exceeds cost in 16, 32 and 48% of water service configurations financed by WTP, WTB and WTW, respectively. Regressions of total cost (R2 = 0.723) and net benefit under WTW (R2 = 0.829) along with analysis of output distributions indicate that parameters determining the profitability of irrigation are different from those determining costs and other measures of net benefit. These findings suggest that the cost-benefit outcomes associated with groundwater-based water

    Public health authorities around the world are increasingly using economic evaluation to set priorities and inform decision making in health policy, especially in the development of health benefit packages. Nevertheless, researchers in low- and middle-income countries (LMICs) encounter many barriers when conducting economic evaluations. In 2015, the Health Intervention and Technology Assessment Program identified key technical and context-specific challenges faced in conducting and using health economic evaluations in LMICs. On the basis of these research findings, the Guide to Economic Analysis and Research (GEAR) online resource (www.gear4health.com) was developed as a reliable aid to researchers in LMICs that would help overcome those challenges. Funded by the Thailand Research Fund and the Bill and Melinda Gates Foundation, GEAR is a free online resource that provides a visual aid tool for planning economic evaluation studies (GEAR mind maps), a repository of national and international economic evaluation guidelines (GEAR guideline comparison), and an active link to a network of volunteer international experts (GEAR: Ask an expert). GEAR will evolve over time to provide relevant, reliable, and up-to-date information through inputs from its users (e.g., periodic survey on methodological challenges) and experts (e.g., in responding to users' questions). The objective of this commentary was to give a brief description of the development and key features of this unique collective information hub aimed at facilitating high-quality research and empowering health care decision makers and stakeholders to use economic evaluation evidence.

  6. Economic value of ecological information in ecosystem-based natural resource management depends on exploitation history.

    Ecosystem approaches to natural resource management are seen as a way to provide better outcomes for ecosystems and for people, yet the nature and strength of interactions among ecosystem components is usually unknown. Here we characterize the economic benefits of ecological knowledge through a simple model of fisheries that target a predator (piscivore) and its prey. We solve for the management (harvest) trajectory that maximizes net present value (NPV) for different ecological interactions and initial conditions that represent different levels of exploitation history. Optimal management trajectories generally approached similar harvest levels, but the pathways toward those levels varied considerably by ecological scenario. Application of the wrong harvest trajectory, which would happen if one type of ecological interaction were assumed but in fact another were occurring, generally led to only modest reductions in NPV. However, the risks were not equal across fleets: risks of incurring large losses of NPV and missing management targets were much higher in the fishery targeting piscivores, especially when piscivores were heavily depleted. Our findings suggest that the ecosystem approach might provide the greatest benefits when used to identify system states where management performs poorly with imperfect knowledge of system linkages so that management strategies can be adopted to avoid those states.

    Unconventional locations outwith general medical practice may prove opportunities for screening. The aim was to determine the resource implications and economics of a screening service using random capillary blood glucose (rCBG) tests to detect raised blood glucose levels in the "at risk" population attending high street optometry practices. A screening service was implemented in optometry practices in North East England: the cost of the service and the implication of different screening strategies was estimated. The cost of a screening test was £5.53-£11.20, depending on the screening strategy employed and who carried out the testing. Refining the screening strategy to target those ≥40 years with BMI of ≥25 kg/m(2) and/or family history of diabetes resulted in a cost per case referred to the GP of £14.38-£26.36. Implementing this strategy in half of optometric practices in England would have the potential to identify up to 150,000 new cases of diabetes and prediabetes a year. Optometry practices provide an effective way of identifying people who would benefit from further investigation for diabetes. Effectiveness could be improved further by improving cooperation and communication between optometrists and medical practitioners. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    2018-02-01

    Full Text Available A study on the status of Bataan’s coastal zones, and the issues on the province’s coastal resource management (CRM programs under an integrated framework was commissioned by the Department of Science and Technology-Region III in the Philippines. Twenty-eight representative coastal villages and 11 water testing sites served as study areas. The research participants totalled to 1,300. Focused group discussions, survey and interviews, laboratory testing, documentary analysis, and literature review were used in the data gathering. It was concluded that the province’s coastal zones are in a disturbed state, which has negative implications to its already subsistent coastal population and important coastal economic activities. The province’s CRM projects have been arbitrary and intermittent. There are too few conservation initiatives due to scarcity of baseline data necessary for more methodical CRM programs. There is poor grassroots level involvement in CRM decision-making processes as well which clearly defeats the essence of integrated coastal management. A coordinated effort to strengthen stakeholder participation in critical CRM stages, and to conduct more comprehensive profilings and assessments of the province’s coastal environment involving the government, academics, and scientists are recommended to substantiate stakeholder involvement and increase the quality of data for CRM projects.

    Understanding patterns of functional trait variation across environmental gradients offers an opportunity to increase inference in the mechanistic causes of plant community assembly. The leaf economics spectrum (LES) predicts global tradeoffs in leaf traits and trait-environment relationships, but few studies have examined whether these predictions hold across different levels of organization, particularly within species. Here, we asked (1) whether the main assumptions of the LES (expected trait relationships and shifts in trait values across resource gradients) hold at the intraspecific level, and (2) how within-species trait correlations scale up to interspecific or among-community levels. We worked with leaf traits of saplings of woody species growing across light and soil N and P availability gradients in temperate rainforests of southern Chile. We found that ITV accounted for a large proportion of community-level variation in leaf traits (e.g., LMA and leaf P) and played an important role in driving community-level shifts in leaf traits across environmental gradients. Additionally, intraspecific leaf trait relationships were generally consistent with interspecific and community-level trait relationships and with LES predictions-e.g., a strong negative intraspecific LMA-leaf N correlation-although, most trait relationships varied significantly among species, suggesting idiosyncrasies in the LES at the intraspecific level. © 2018 by the Ecological Society of America.

    Full Text Available The aim of this work is to analyze the spatial distribution of potential pollution pathways of water resources given the economic activity in the Mexican border state of Sonora and propose a regional distribution in relation to cancer mortality rates across the state. The methodology is based in an exploratory and inferential data analysis using two sources of primary data: wastewater discharge concessions registered in the Public Registry on Water Rights [Registro Público de Derechos de Agua] (REPDA and the records generated by the National Health Information System [Sistema Nacional de Información en Salud] (SINAIS in the period 1998-2011 based on the International Classification of Disease (ICD-10. The spatial concentration analysis allows for the identification of specific cancer mortality causes at the regional level. Results indicate that the projected adjustments to the regulation NOM-250-SSA1-2014, which controls a subset of pollutants common in mining activity surroundings, is a matter of regional concern.

  11. A new economic model for resource industries-implications for universities

    1993-01-01

    The upheaval in the US petroleum industry has had repercussions in the university community. Geoscience enrollments have plummeted, financial support has declined, and there are rumors that some programs have reduced mathematical rigor to maintain enrollment. While the adverse affects have been widespread, there is disagreement about implications and expectations for the future. Some argue that emphasis on short-term profitability produces ill-conceived, precipitous reactions which perpetuate the turmoil. Others respond that the resource and environmental needs of a burgeoning global population will ensure long-term growth. Both arguments miss the point. The fundamental economic structure of the industry is changing from revenue-driven to marginal-return. In marginal-return industries, investments depend on quantitative assessments of risk and return, and the use of interdisciplinary teams is the norm. University programs must educate students in engineering design and structured decision-making processes, develop integrated numeric models and create infrastructures that support multidisciplinary collaboration. Educational programs must begin teaching principles of engineering design and structured decision-making, with increased emphasis on outreach to the experienced employee. Meeting those needs will require closer collaboration between industry and the universities. Universities that are successful will reap a fringe benefit; their graduate will be better-qualified to be leaders in the environmentally geoscience field, which one day may be bigger than the oil industry

    Full Text Available At the turn of the twentieth century Italy registered a lowest-low fertility level, i.e., a total fertility rate of 1.26 children per woman in 2000. In this paper we investigate whether and how in that period economic resources and, in particular, income and job stability were linked with couples' decisions to enter parenthood. With this aim, we use data from ECHP and carry out a longitudinal analysis on a sample of childless married couples to study the transition to their first child. Results show that the couples' employment arrangement played some role in first child rates, with the single earner arrangement experiencing the highest first birth rates. We also find that employed women with labour income have much lower first birth rates than non-working women, while no evidence is found for male earnings and other sources of income. As concerns job instability, we find evidence that it was not significantly linked with the transition to first time parenthood during the investigated period.

    China's rapid and sustained economic growth offers an opportunity to ask whether the advantages of growth diffuse throughout an economy, or remain localized in areas where the growth has been the greatest. A critical policy area in China has been the health system, and health inequality has become an issue that has led the government to broaden national health insurance programs. This study investigates whether health system resources and performance have converged over the past 30 years across China's 31 provinces. To examine geographic variation of health system resources and performance at the provincial level, we measure the degree of sigma convergence and beta convergence in indicators of health system resources (structure), health services utilization (process), and outcome. All data are from officially published sources: the China Health Statistics Year Book and the China Statistics Year Book. Sigma convergence is found for resource indicators, whereas it is not observed for either process or outcome indicators, indicating that disparities only narrowed in health system resources. Beta convergence is found in most indicators, except for 2 procedure indicators, reflecting that provinces with poorer resources were catching up. Convergence found in this study probably reflects the mixed outcome of government input, and market forces. Thus, left alone, the equitable distribution of health care resources may not occur naturally during a period of economic growth. Governmental and societal efforts are needed to reduce geographic health variation and promote health equity. © The Author(s) 2016.

    Worldwide, falls among older people are a public health concern because of their frequency and adverse consequences in terms of morbidity, mortality, and quality of life, as well as their impact on health system services and costs. This epidemiological review outlines the public health burden of falls and fall-related injuries and the impact of population aging. The magnitude of the problem is described in terms of the classification of falls and measurement of outcomes, including fall incidence rates across settings, sociodemographic determinants, international trends, and costs of falls and fall-related injuries. Finally, public health approaches to minimize falls risk and consequent demand on health care resources are suggested.

    Social services aimed at the elderly are facing great challenges caused by progressive aging of the global population but also by the constant pressure to spend funds in a rational manner. This paper focuses on analyzing the investments into human resources aimed at enhancing home care for the elderly since many countries have recorded progress in the area over the past years. The goal of this paper is to stress the significance of performing an economic analysis of the investment. This paper combines statistical analysis methods such as correlation and regression analysis, methods of economic analysis, and scenario method. The economic analysis of investing in human resources for home care service in Serbia showed that the both scenarios of investing in either additional home care hours or more beneficiaries are cost-efficient. However, the optimal solution with the positive (and the highest) value of economic net present value criterion is to invest in human resources to boost the number of home care hours from 6 to 8 hours per week and increase the number of the beneficiaries to 33%. This paper shows how the statistical and economic analysis results can be used to evaluate different scenarios and enable quality decision-making based on exact data in order to improve health and quality of life of the elderly and spend funds in a rational manner.

    Full Text Available Gender aspects of the access to economic resources within the processes of terrritorialization are important at macro-level for the designing processes of sustainable rural development, as well as at the micro-level, for shaping livelihoods of men and women in rural areas. The research is based on the assumption that access to economic resources is gendered. Starting from the findings of previous researches (Blagojević, 2010, Babović and Vuković, 2008, Trajković, 2002, Korać, 1991 on gender relations in rural areas, the research presented in this paper is motivated by intention to get deeper knowledge about gender aspects of access to economic resources throughout the processes of territorialization (Battaglini, 2014. The process of territorialization is the process of 'embedding' actors in the place of living, which unfolds through their interactions with nature and other resources available for production and securing livelihoods. Territorialization patterns, the access to endogenous and egzogenous resources available in the given territory (Stimson, Stough and Njikamp, 2011 are important elements of positioning of men and women in the processes of rural development. Qualitative research findings indicate that gender and generation differences in the territorialization patterns are present in the key phases of symbolization, reification and organization, and they are influenced by specific norms and values as well as power relations.

    Full Text Available Subject: technical and economic processes and aspects of handling wastes and secondary material resources; stages of transition of anthropogenic object of environment to wastes and secondary material resources; technical possibility and economic feasibility of using secondary material resources as a secondary raw material for making products, providing energy, works, services. The problem of economy and rational use of material and power resources is relevant and significant within the limits of maintenance of a strategic course of Russia on innovative sustainable development. In this article, issues of actualization and harmonization of the regulatory and legal base in the field of management of wastes and secondary material resources are considered from the viewpoint of maintenance of minimization of waste formation and maximum use of secondary material resources in an industrial-economic cycle, provision of economic incentives for innovative activity in the given field. The actual multi-plan problem, chosen here as a topic of research, concerns regulations in management of wastes and secondary material resources in construction complex, in which economic, civil-law, ecological, social, industrial and legal relations are closely coordinated and define a subject of the present research. Production and consumption waste is a dangerous anthropogenic object of the environment but at the same time, it is a valuable secondary material resource. The non-use of wastes to be recycled as secondary raw materials for energy generation, production and, as a result, their increasing accumulation in the environment causes irreparable harm to natural objects and human health due to their dangerous properties. Research objectives: scientific and methodological substantiation of legal regulation, economic basis for formation of wastes and secondary material resources management system (on the example of construction complex and building materials industry

  2. Generalized DSS shell for developing simulation and optimization hydro-economic models of complex water resources systems

    2013-04-01

    Hydrologic-economic models allow integrated analysis of water supply, demand and infrastructure management at the river basin scale. These models simultaneously analyze engineering, hydrology and economic aspects of water resources management. Two new tools have been designed to develop models within this approach: a simulation tool (SIM_GAMS), for models in which water is allocated each month based on supply priorities to competing uses and system operating rules, and an optimization tool (OPT_GAMS), in which water resources are allocated optimally following economic criteria. The characterization of the water resource network system requires a connectivity matrix representing the topology of the elements, generated using HydroPlatform. HydroPlatform, an open-source software platform for network (node-link) models, allows to store, display and export all information needed to characterize the system. Two generic non-linear models have been programmed in GAMS to use the inputs from HydroPlatform in simulation and optimization models. The simulation model allocates water resources on a monthly basis, according to different targets (demands, storage, environmental flows, hydropower production, etc.), priorities and other system operating rules (such as reservoir operating rules). The optimization model's objective function is designed so that the system meets operational targets (ranked according to priorities) each month while following system operating rules. This function is analogous to the one used in the simulation module of the DSS AQUATOOL. Each element of the system has its own contribution to the objective function through unit cost coefficients that preserve the relative priority rank and the system operating rules. The model incorporates groundwater and stream-aquifer interaction (allowing conjunctive use simulation) with a wide range of modeling options, from lumped and analytical approaches to parameter-distributed models (eigenvalue approach).

    The rural economy in India is as yet only partially monetized and continues to retain its semi-subsistence character, while at the same time undergoing the process of becoming more monetized and market-orientated. A large field study was conducted in rural Karnataka, a state in southern India, which uncovers the relations between the energy situations of the rural social classes and their access to labour, land, cash and physical assets. Of equal significance are regional variations in ecology, rainfall and irrigation. The study's principal focus is the rural household, but it also includes some analysis of the energy dimensions in agricultural activities and small-scale rural services. Eight villages were covered by the survey, one in each district, carefully selected to reflect the geographic, climatic, biomass-resource and socio-economic features of Karnataka. In each village an average of 55 households were studied in depth, making up a total of 450 households. Clear and marked differentiations are uncovered between the rural social classes in various aspects of energy production, purchase, sale and consumption, as well as in labour and cash inputs into the energy flows. It is found that traditional forms of biomass are still the dominant type of energy for all rural strata, and that only the rural middle class can be said to have begun the transition towards modern fuels, although its consumption of modern fuels is still negligibly small in absolute terms. The study reveals that the rural middle class faces no energy crisis, while the 'intermediate' class of the small peasantry is just about managing to make ends meet in energy terms. In contrast to this, the rural wage labour class continues to remain in a state of energy crisis. (author)

    2016-04-01

    Information is valuable when it improves decision-making (e.g., actions can be adjusted to better suit the situation at hand) and enables the mitigation of damage. However, quantifying the value of information is often difficult. Here we explore a general approach to understand the economic value of drought information for water managers framing our approach in the precautionary principle that reminds us that uncertainty is not a reason to postpone or avoid action. We explore how decision making can disregard uncertain effects, taking a short-term approach and focusing instead on the certain costs and benefits of taking action. Two main questions arise: How do we know that advanced drought information is actually helping decisions?; and What is the value of information in the decision process? The approach is applied to several regulated water resources systems in Spain. It first views drought information as a factor in the decision process which can be used by water managers to reduce uncertainty. Second, the value of drought information is the expected gain in a decision outcome (utility) from using additional information. Finally, the gains of improved information are compared with the information collection costs. Here we estimate the value by taking into account the accuracy of the drought information, the subjective probabilities about the value, analyzed as Bayesian probabilities, and the ability or skill of the stakeholders to apply the drought information to modify their actions. Since information may be considered a public good (non-rivalry and non-excludability), it may justify public policy in the provision of information, considering social costs and benefits. The application of the framework to the Spanish case studies shows that information benefits exceeds to costs when drought frequency is 20-40% above normal values; below these values uncertainty in the decisions dominate the results; above these values, the management decisions are limited even

    Highlights: • A new cycle was designed to improve basic organic Rankine cycle performance. • Peng Robinson equation of state was used to obtain properties of working fluids. • Operating parameters were optimized with three different objective functions. • Efficiency of new organic Rankine cycle is higher than other considered cycles. • Return on investment of new cycle for Iran is more than France and America. - Abstract: The main goal of this study is to propose and investigate a new organic Rankine cycle based on three considered configurations: basic organic Rankine cycle, regenerative organic Rankine cycle and two-stage evaporator organic Rankine cycle in order to increase electricity generation from geothermal sources. To analyze the considered cycles’ performance, thermodynamic (energy and exergy based on the first and second laws of thermodynamics) and economic (specific investment cost) models are investigated. Also, a comparison of cycles modeling results is carried out in optimum conditions according to different optimization which consist thermodynamic, economic and thermo-economic objective functions for maximizing exergy efficiency, minimizing specific investment cost and applying a multi-objective function in order to maximize exergy efficiency and minimize specific investment cost, respectively. Optimized operating parameters of cycles include evaporators and regenerative temperatures, pinch point temperature difference of evaporators and degree of superheat. Furthermore, Peng Robinson equation of state is used to obtain thermodynamic properties of isobutane and R123 which are selected as dry and isentropic working fluids, respectively. The results of optimization indicate that, thermal and exergy efficiencies increase and exergy destruction decrease especially in evaporators for both working fluids in new proposed organic Rankine cycle compared to the basic organic Rankine cycle. Moreover, the amount of specific investment cost in new

    2011-03-01

    Full Text Available The development of the complex and multi-dimensional urban socio-economic system creates impacts on natural capital and human capital, which range from a local to a global scale. An emergy-based multiple spatial scale analysis framework and a rigorous accounting method that can quantify the values of human-made and natural capital losses were proposed in this study. With the intent of comparing the trajectory of Beijing over time, the characteristics of the interface between different scales are considered to explain the resource trade and the impacts of emissions. In addition, our improved determination of emergy analysis and acceptable management options that are in agreement with Beijing’s overall sustainability strategy were examined. The results showed that Beijing’s economy was closely correlated with the consumption of nonrenewable resources and exerted rising pressure on the environment. Of the total emergy use by the economic system, the imported nonrenewable resources from other provinces contribute the most, and the multi‑scale environmental impacts of waterborne and airborne pollution continued to increase from 1999 to 2006. Given the inputs structure, Beijing was chiefly making greater profits by shifting resources from other provinces in China and transferring the emissions outside. The results of our study should enable urban policy planners to better understand the multi-scale policy planning and development design of an urban ecological economic system.

    This work expands upon Swallow's theoretical analysis of interactions between renewable and non-renewable resources. In this comment the interaction is such that the renewable resource prefers the non-renewable environment, as opposed to SwallowÕs (op cit) case of the non-renewable environment being essential to the renewable resource. We find that this difference strongly affects the results, and makes the resources change from being complements to being substitutes, i.e. in the essential ca...

  11. Economics of technological change and the natural environment: How effective are innovations as a remedy for resource scarcity?

    International Nuclear Information System (INIS)

    Bretschger, Lucas

    2005-01-01

    The paper aims to substantiate the importance of endogenous innovations when evaluating the compatibility of natural resource use and economic development. It explains that technological change has the potential to compensate for natural resource scarcity, diminishing returns to capital, poor input substitution, and material balance restrictions, but is limited by various restrictions like fading returns to innovative investments and rising research costs. It also shows how innovative activities are fostered by accurate price signals and research-favouring sectoral change. The simultaneous effects of increasing technical knowledge, decreasing resource inputs, and increasing world population largely determine the chances of long-run sustainable development. Consequently, future research has to be directed at a more thorough understanding of the mechanisms driving innovations in the presence of natural resource scarcity

    2001-01-01

    The ''entropy'' model for quantitative assessment of the impact of the electricity generating systems is discussed in the paper. Introduction of the ''entropy'' notion opens an opportunity to come to a new understanding of the competitiveness of the electricity generating technologies under taking into account not only economic but also environmental resources. The criterion of the effectiveness should be formulated as production the unit of electricity under minimal dissipation of human energy and natural resources or, in another words, under minimal increase of the 'nooentropy' in the production system. Under such wide definition, the effectiveness of a technology for electricity production becomes a very important index of the sustainability. The assessment of the ''nooentropy'' effectiveness of the main full-energy-chain electricity production options with normalization to natural resources of Russia has demonstrated important advantages of the nuclear power which are missed in another models of the system analysis, specifically, less impact on natural resource.

    Expanded mining and use of coal resources in the Rocky Mountain region of the western United States will have substantial impacts on water resources, environmental amenities, and social and economic conditions. The U.S. Geological Survey has completed a 3-year assessment of the Yampa River basin, Colorado and Wyoming, where increased coal-resource development has begun to affect the environment and quality of life. Economic projections of the overall effects of coal-resource development were used to estimate water use and the types and amounts of waste residuals that need to be assimilated into the environment. Based in part upon these projections, several physical-based models and other semiquantitative assessment methods were used to determine possible effects upon the basin's water resources. Depending on the magnitude of mining and use of coal resources in the basin, an estimated 0.7 to 2.7 million tons (0.6 to 2.4 million metric tons) of waste residuals may be discharged annually into the environment by coal-resource development and associated economic activities. If the assumed development of coal resources in the basin occurs, annual consumptive use of water, which was approximately 142,000 acre-feet (175 million cubic meters) during 1975, may almost double by 1990. In a related analysis of alternative cooling systems for coal-conversion facilities, four to five times as much water may be used consumptively in a wet-tower, cooling-pond recycling system as in once-through cooling. An equivalent amount of coal transported by slurry pipeline would require about one-third the water used consumptively by once-through cooling for in-basin conversion. Current conditions and a variety of possible changes in the water resources of the basin resulting from coal-resource development were assessed. Basin population may increase by as much as threefold between 1975 and 1990. Volumes of wastes requiring treatment will increase accordingly. Potential problems associated

  14. A new and integrated hydro-economic accounting and analytical framework for water resources: a case study for North China.

    2008-09-01

    Water is a critical issue in China for a variety of reasons. China is poor of water resources with 2,300 m(3) of per capita availability, which is less than 13 of the world average. This is exacerbated by regional differences; e.g. North China's water availability is only about 271 m(3) of per capita value, which is only 125 of the world's average. Furthermore, pollution contributes to water scarcity and is a major source for diseases, particularly for the poor. The Ministry of Hydrology [1997. China's Regional Water Bullets. Water Resource and Hydro-power Publishing House, Beijing, China] reports that about 65-80% of rivers in North China no longer support any economic activities. Previous studies have emphasized the amount of water withdrawn but rarely take water quality into consideration. The quality of the return flows usually changes; the water quality being lower than the water flows that entered the production process initially. It is especially important to measure the impacts of wastewater to the hydro-ecosystem. Thus, water consumption should not only account for the amount of water inputs but also the amount of water contaminated in the hydro-ecosystem by the discharged wastewater. In this paper we present a new accounting and analytical approach based on economic input-output modelling combined with a mass balanced hydrological model that links interactions in the economic system with interactions in the hydrological system. We thus follow the tradition of integrated economic-ecologic input-output modelling. Our hydro-economic accounting framework and analysis tool allows tracking water consumption on the input side, water pollution leaving the economic system and water flows passing through the hydrological system thus enabling us to deal with water resources of different qualities. Following this method, the results illustrate that North China requires 96% of its annual available water, including both water inputs for the economy and contaminated

    Full Text Available Abstract Background People with Parkinson's disease are twice as likely to be recurrent fallers compared to other older people. As these falls have devastating consequences, there is an urgent need to identify and test innovative interventions with the potential to reduce falls in people with Parkinson's disease. The main objective of this randomised controlled trial is to determine whether fall rates can be reduced in people with Parkinson's disease using exercise targeting three potentially remediable risk factors for falls (reduced balance, reduced leg muscle strength and freezing of gait. In addition we will establish the cost effectiveness of the exercise program from the health provider's perspective. Methods/Design 230 community-dwelling participants with idiopathic Parkinson's disease will be recruited. Eligible participants will also have a history of falls or be identified as being at risk of falls on assessment. Participants will be randomly allocated to a usual-care control group or an intervention group which will undertake weight-bearing balance and strengthening exercises and use cueing strategies to address freezing of gait. The intervention group will choose between the home-based or support group-based mode of the program. Participants in both groups will receive standardized falls prevention advice. The primary outcome measure will be fall rates. Participants will record falls and medical interventions in a diary for the duration of the 6-month intervention period. Secondary measures include the Parkinson's Disease Falls Risk Score, maximal leg muscle strength, standing balance, the Short Physical Performance Battery, freezing of gait, health and well being, habitual physical activity and positive and negative affect schedule. Discussion No adequately powered studies have investigated exercise interventions aimed at reducing falls in people with Parkinson's disease. This trial will determine the effectiveness of the exercise

    Falls among older adults can cause serious morbidity and pose economic burdens on society. Older age is a known risk factor for falls and age has been shown to influence the effectiveness of fall prevention programs. To our knowledge, no studies have explicitly investigated whether cost-effectiveness of a multifactorial fall prevention intervention (the intervention) is influenced by age. This economic evaluation explores: 1) the cost-effectiveness of a multifactorial fall prevention intervention compared to usual care for community-dwelling adults ≥ 75 years at risk of falling in Canada; and 2) the influence of age on the cost-effectiveness of the intervention. Net benefit regression was used to examine the cost-effectiveness of the intervention with willingness-to-pay values ranging from $0-$50,000. Effects were measured as change in the number of falls, from baseline to 6-month follow-up. Costs were measured using a societal perspective. The cost-effectiveness analysis was conducted for both the total sample and by age subgroups (75-84 and 85+ years). For the total sample, the intervention was not economically attractive. However, the intervention was cost-effective at higher willingness-to-pay (WTP) (≥ $25,000) for adults 75-84 years and at lower WTP (cost-effectiveness of the intervention depends on age and decision makers' WTP to prevent falls. Understanding the influence of age on the cost-effectiveness of an intervention may help to target resources to those who benefit most. Retrospectively registered.

    Falls pose a major threat to the well-being and quality of life of older people. Falls can result in fractures and other injuries, disability and fear and can trigger a decline in physical function and loss of autonomy. This article synthesises recent published findings on fall risk and mobility assessments and fall prevention interventions and considers how this field of research may evolve in the future. Fall risk topics include the utility of remote monitoring using wearable sensors and recent work investigating brain activation and gait adaptability. New approaches for exercise for fall prevention including dual-task training, cognitive-motor training with exergames and reactive step training are discussed. Additional fall prevention strategies considered include the prevention of falls in older people with dementia and Parkinson's disease, drugs for fall prevention and safe flooring for preventing fall-related injuries. The review discusses how these new initiatives and technologies have potential for effective fall prevention and improved quality of life. It concludes by emphasising the need for a continued focus on translation of evidence into practice including robust effectiveness evaluations of so that resources can be appropriately targeted into the future.

    Full Text Available The problems of agricultural land accounting are investigated with the aim of developing methodological approaches for reliable accounting of land resources transactions that will become the basis for improving control procedures for land conservation and protection. One of the most important priorities of state policy, the condition for stability and development of the country’s national economy is a scientifically grounded land use policy, which serves as an economic indicator of the development of the state and one of the ways to overcome the financial and economic crisis in the country when it occurs. World practice has shown that the only universal exchange equivalent in the way of overcoming the economic crisis of any state is natural resources, and one of the significant, practically reproducible resources is land. Depending on the categories of lands, they may be subject to both ownership rights and full ownership. However, this property right remains inadequate, as owners of land plots cannot use them freely (sell, transfer, inherit, give, etc..

    During different planning periods, human resources factor has been considerably increased in the health-care sector. The main goal is to determine economic planning conditions and equilibrium growth for services level and specialized workforce resources in health-care sector and also to determine the gap between levels of health-care services and specialized workforce resources in the equilibrium growth conditions and their available levels during the periods of the first to fourth development plansin Iran. In the study after data collection, econometric methods and EViews version 8.0 were used for data processing. The used model was based on neoclassical economic growth model. The results indicated that during the former planning periods, although specialized workforce has been increased significantly in health-care sector, lack of attention to equilibrium growth conditions caused imbalance conditions for product level and specialized workforce in health-care sector. In the past development plans for health services, equilibrium conditions based on the full employment in the capital stock, and specialized labor are not considered. The government could act by choosing policies determined by the growth model to achieve equilibrium level in the field of human resources and services during the next planning periods.

    2016-12-01

    Full Text Available This article examines the impact of central government transfers and other sources of regional budget revenues (income tax and property tax on per capita GRP growth in Russian regions. Analysis is based on official data of 78 regions for the period 2005-2014. The results indicate that transfers, while intending to be an instrument of regional incomes equalization, are negatively associated with economic growth of Russian regions, which contrasts with other estimates of federal transfers’ impact on regional economic growth in Russia. This phenomenon can be explained by high rate of social expenditures in regional governments’ spending. At the same time there is positive relationship between regional budget’s investment and economic growth that indicates significant role of public goods for regional economic development. This study can be considered as confirmation of those conclusions concerning impact of fiscal decentralization on economic growth of Russian regions which claim that current system of intergovernmental relations on sub-national level cannot embody the benefits of fiscal federalism as a principle of effective regional development. Significant factors of regional per capita GRP growth are own sources of region’s budget revenues which reflect costs of doing business. So the rise in property taxes retards economic growth in a region. For the regional authorities it makes sense to operate more flexibly with this tool, especially in periods of economic recession when inflow of corporate income tax to budget tends to decrease

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

    The MontanAqua project aims to study the water resources management in the region Sierre-Montana (Valais, Switzerland). Land use is known to have an influence on the water resources (soil moisture dynamic, soil sealing, surface runoff and deep percolation). Thus land use modelling is of importance for the water resources management. An actual land use map was produced using infrared imagery (Niklaus 2012, Fig.1). Land use changes are known to be mainly drived by socio-economic factors as well as climatic factors (Dolman et al. 2003). Potential future Land uses was separatly predicted according to 1-. socio-economic and 2-. climatic/abiotic drivers : 1. 4 socio-economic scenarios were developped with stakeholders (Schneider et al. 2013) between 2010 and 2012. We modeled those socio-economic scenarios into a GIS application using Python programming (ModelBuilder in ArcGIS 10) to get a cartographic transcription of the wishes of the stakeholders for their region in 2050. 2. Uncorrelated climatic and abiotic drivers were used in a BIOMOD2 (Georges et al. 2013) framework. 4 models were used: Maximum Entropy (MAXENT), Multiple Adaptive Regression Splines (MARS), Classification Tree Analysis (CTA) and the Flexible Discriminant Analysis (FDA) to predict grassland, alpine pasture, vineyards and forest in our study region. Climatic scenarios were then introduced into the models to predict potential land use in 2050 driven only by climatic and abiotic factors The comparison of all the outputs demonstrates that the socio-economic drivers will have a more important impact in the region than the climatic drivers (e.g. -70% grassland surface for the worst socio-economic scenario vs. -40% of grassland surface for the worst climatic models). Further analysis also brings out the sensitivity of the grassland/alpine pasture system to the climate change and to socio-economic changes. Future work will be to cross the different land use maps obtained by the two model types and to use

    From Boston to Beijing, thousands of students traveled to San Francisco for the 2011 AGU Fall Meeting. Of those who participated, 183 students were able to attend thanks to AGU's student travel grant program, which assists students with travel costs and seeks to enrich the meeting through ethnic and gender diversity. Students at Fall Meeting enjoyed a variety of programs and activities designed to help them better network with their peers, learn about new fields, and disseminate their research to the interested public. More than 800 students attended AGU's first annual student mixer, sharing drinks and ideas with fellow student members and future colleagues as well as forging new friendships and intellectual relationships.

  13. Troubled times, troubled relationships: how economic resources, gender beliefs, and neighborhood disadvantage influence intimate partner violence.

    We evaluate race/ethnicity and nativity-based disparities in three different types of intimate partner violence (IPV) and examine how economic hardship, maternal economic dependency, maternal gender beliefs, and neighborhood disadvantage influence these disparities. Using nationally representative data from urban mothers of young children who are living with their intimate partners (N = 1,886), we estimate a series of unadjusted and adjusted logit models on mothers' reports of physical assault, emotional abuse, and coercion. When their children were age 3, more than one in five mothers were living with a partner who abused them. The prevalence of any IPV was highest among Hispanic (26%) and foreign-born (35%) mothers. Economic hardship, economic dependency on a romantic partner, and traditional gender beliefs each increased women's risk for exposure to one or more types of IPV, whereas neighborhood conditions were not significantly related to IPV in adjusted models. These factors also explained most of the racial/ethnic and nativity disparities in IPV. Policies and programs that reduce economic hardship among women with young children, promote women's economic independence, and foster gender equity in romantic partnerships can potentially reduce multiple forms of IPV.

    2012-12-01

    Falling is a major clinical problem; especially, in elderly population as it often leads to fractures, immobilization, poor quality of life and life-span reduction. Given the growing body of evidences on the physiopathology of balance disorders in humans, in recent years the approach of research on falls has completely changed and new instruments and new definitions have been formulated. Among them, the definition of "idiopathic faller" (i.e. no overt cause for falling in a given subject) represented a milestone in building the "science of falling". This review deals with the new determinants of the neurobiology of falling: (1) the role of motor impairment and particularly of those "mild parkinsonian signs" frequently detectable in elderly subjects, (2) the role of executive and attentive resources when coping with obstacles, (3) the role of vascular lesions in "highest level gait disorder" (a condition tightly connected with senile gait, cautious gait and frailty), (4) the role of the failure of automaticity or inter-limbs coordination/symmetry during walking and such approach would definitely help the development of screening instrument for subjects at risk (still lacking in present days). This translational approach will lead to the development of specific therapeutic interventions.

    The key messages are: Global sustainability depends on the creation and implementation of effective policies to support the dynamic Asia-Pacific region to transition to a new sustainable industrial system; This will be instrumental to deal with the dual objectives of increasing the material standard of living of people and reducing poverty, to ensure the integrity of resources and the environment; Resource efficient infrastructure associated with transport, energy and housing is critical, and massive amounts of new infrastructure are currently being planned. There is a twenty to thirty year window of opportunity for this transformation; The challenge for public policy is to achieve a sustainability transition, enabled by resource efficiency and systems innovation despite the inherent growth dynamic of the industrial transformation. What is required is a new 'industrial revolution' that provides food, housing, mobility, energy, and water with only about 20% of the per-capita resource use and emissions found in current systems.

    This study investigates the causal relationship between clean and non-clean energy consumption and economic growth in Brazil over the period of 1980–2009. Clean energy consumption at aggregated level of total renewable energy consumption and disaggregated levels of hydroelectric, new renewables, and nuclear energy consumption are tested within a production function framework. A cointegration test reveals a long-term equilibrium relationship between real output, capital, labor, and renewable and non-renewable energy consumption at aggregated level, and a long-term equilibrium relationship between real output, capital, labor, and hydroelectric/new renewables/nuclear and fossil fuel energy consumption at disaggregated level. The capital, labor, and new renewables elasticities of real output are positive and statistically significant, other energy consumption item's elasticities are insignificant. The results from error correction model reveal the interdependencies between new renewables, nuclear, fossil fuel, and total non-renewable energy consumption and economic growth, the unidirectional causality from hydroelectric/total renewable consumption to economic growth, the substitutability between new renewables and fossil fuel consumption, and the substitutability between new renewables and nuclear energy consumption. Additionally, nuclear and new renewables energy consumption responds to bring the system back to equilibrium. Overall, aggregated analysis may obscure the relationship between different types of clean energy consumption and economic growth. - Highlights: • We model three kinds of clean energy and non-clean energy consumption and real GDP. • There is fossil fuel consumption–economic growth bidirectional causality. • There is new renewables consumption–economic growth bidirectional causality. • There is nuclear energy consumption–economic growth bidirectional causality. • Substitutability exists for new renewables–fossil fuel or new

    2018-02-01

    Full Text Available The challenge of meeting increasing water, energy, and food needs is linked not only to growing demands globally, but also to the growing interdependency between these interconnected resource systems. Pressures on these systems will emerge to become hotspots with different characteristics, and will require a fresh look at the challenges existing both within each of the resource systems and at their respective interfaces. Proposing solutions to address different resource hotspots must be multi-faceted and need to acknowledge the multiple dimensions of the biophysical water, energy, and food systems, and the players connected with them. This commentary first explores the multiple dimensions of water, energy, and food systems as these relate to government, business, and society. It then identifies contemporary critical questions at the interface of these stressed resource systems. A 3-Filter framework is then introduced for vetting the feasibility of proposed resource allocation scenarios and to account for the bio-physical resource interactions and trade-offs, the stakeholder interactions and trade-offs, and to address governance and financing schemes for carrying forward the implementation of those scenarios.

  3. Technical and economic viability of electric power plants on the basis of renewable energy resources regarding hierarchical structure

    2017-01-01

    Full Text Available The article deals with power stations working on the basis of non-renewable energy resources and finite resources which will inevitably come to depletion in the future. These installations produce considerable negative impact on the environment, including air pollution. It is noted that considerable amounts of emissions of harmful substances accounts for the share of small thermal installations which aren’t always considered in calculations of pollution. The author specifies that emission reduction of harmful substances should be achieved due to wider use of environmentally friendly renewable energy resources. It is recommended to use hierarchical structure with the priority of ecological and social conditions of the region for technical and economic viability of consumers’ power supply systems and installations, based on renewable energy resources use. At the same time the author suggests considering federal, regional and object levels of viability. It is recommended to consider the main stages of lifecycle of an object for object level: designing, construction, operation, reconstruction of an object and its preservation. The author shows the example of calculation of power plant efficiency, based on renewable energy resources during its reconstruction, followed by power generation increase.

  5. Assessing the Total Economic Value of Improving Water Quality to Inform Water Resources Management: Evidence and Challenges from Southeast Asia

    Jalilov, S.; Fukushi, K.

    2016-12-01

    Population growth, high rates of economic development and rapid urbanization in the developing countries of Southeast Asia (SEA) have resulted in degradation and depletion of natural resources, including water resources and related ecosystem services. Many urban rivers in the region are highly polluted with domestic, industrial and agricultural wastes. Policymakers are often aware of the direct value of water resources for domestic and industrial consumption, but they often underestimate the indirect value of these functions, since they are not exchanged in the market and do not appear in national income accounts. Underestimation of pollution and over-exploitation of water resources result in a loss of these benefits and have adverse impacts on nearby residents, threatening the long-term sustainable development of natural resources in the region. Behind these constraints lies a lack of knowledge (ignorance) from governments that a clean water environment could bring significant economic benefits. This study has been initiated to tackle this issue and to foster a more rational approach for sustainable urban development in Metro Manila in the Philippines. We applied a Contingent Valuation Method (CVM) based on Computer-Assisted Personal Interviewing (CAPI) technique. Results show that users are willing to pay up to PHP 102.42 (2.18) monthly to improve quality of urban waterbodies whereas nonusers are willing to pay up to PHP 366.53 (7.80) as one-time payment towards water quality improvement. The estimated monetary value of water quality improvements would be a useful variable in cost-benefit analyses of various water quality-related policies, in both public and private sectors in Metro Manila. This survey design could serve as a useful template for similar water quality studies in other SEA countries.

  6. Evolution of the societal value of water resources for economic development versus environmental sustainability in Australia from 1843 to 2011

    2017-12-01

    The scale of human activity in the last 200 years has reached a point where our actions are affecting the global biophysical environment to such a degree and at such a speed that irreversible effects are being observed. Societal values are generally seen as leading to changes in human decisions and actions, but have not been addressed adequately in current water management, which is blind to changes in the social drivers for, or societal responses to, management decisions. This paper describes the evolution of societal value of water resources in Australia over a period of 169 years. These values were classified into two groups: supporting economic development versus supporting environmental sustainability. The Sydney Morning Herald newspaper was used as the main data source to track the changes in the societal value of water resources. Content analysis was used to create a description of the evolution of these societal values. Mathematical regression analysis, in combination of transition theory, was used to determine the stages of transition of the societal value, and the co-evolved social-ecological framework was used to explain how the evolution of societal values interacted with water management policies/practices and droughts. Key findings included that the transition of the societal value of water resources fitted the sigmoid curve - a conceptual S curve for the transition of social systems. Also, the transition of societal value of water resources in Australia went through three stages: (1) pre-development (1900s-1960s), when the societal value of water resources was dominated by economic development; (2) take-off (1962-1980), when the societal value of water resources reflected the increasing awareness of the environment due to the outbreak of pollution events; (3) acceleration (1981-2011), when the environment-oriented societal value of water resources combined with the Millennium Drought to trigger a package of policy initiatives and management practices

    Tropical forests dominated by only one or two tree species occupy tens of millions of hectares in Ammonia In many cases, the dominant species produce fruits, seeds, or oils of economic importance. Oligarchic (Gr. oligo = few, archic = dominated or ruled by) forests of six economic species, i. e., Euterpe oleracea, Grias peruviana, Jessenia bataua, Mauritia flexuosa, Myrciaria dubia, and Orbignya phalerata, were studied in Brazil and Peru Natural populations of these species contain from 100 to 3,000 conspecific adult trees/ha and produce up to 11.1 metric tons of fruit/hd/yr. These plant populations are utilized and occasionally managed, by rural inhabitants in the region. Periodic fruit harvests, if properly controlled have only a minimal impact on forest structure and function, yet can generate substantial economic returns Market-oriented extraction of the fruits produced by oligarchic forests appears to represent a promising alternative for reconciling the development and conservation of Amazonian forests.

    Full Text Available The development of a country depends greatly on how much information its citizenry are exposed to. Information is so crucial that it has been recognized as the fifth factor of production. Information has no substitute when it comes to the national development because it has been identified as the driver of economic growth and productivity. The paper discussed the roles of public libraries in Nigeria and also examined various ways in which public libraries can help curb unemployment among youths by providing them with timely and accurate information. It concluded that public libraries should identify themselves with the aspiration of economic development of the country.

  9. The Identification of Filters and Interdependencies for Effective Resource Allocation: Coupling the Mitigation of Natural Hazards to Economic Development.

    Science.gov (United States)

    Agar, S. M.; Kunreuther, H.

    2005-12-01

    Policy formulation for the mitigation and management of risks posed by natural hazards requires that governments confront difficult decisions for resource allocation and be able to justify their spending. Governments also need to recognize when spending offers little improvement and the circumstances in which relatively small amounts of spending can make substantial differences. Because natural hazards can have detrimental impacts on local and regional economies, patterns of economic development can also be affected by spending decisions for disaster mitigation. This paper argues that by mapping interdependencies among physical, social and economic factors, governments can improve resource allocation to mitigate the risks of natural hazards while improving economic development on local and regional scales. Case studies of natural hazards in Turkey have been used to explore specific "filters" that act to modify short- and long-term outcomes. Pre-event filters can prevent an event from becoming a natural disaster or change a routine event into a disaster. Post-event filters affect both short and long-term recovery and development. Some filters cannot be easily modified by spending (e.g., rural-urban migration) but others (e.g., land-use practices) provide realistic spending targets. Net social benefits derived from spending, however, will also depend on the ways by which filters are linked, or so-called "interdependencies". A single weak link in an interdependent system, such as a power grid, can trigger a cascade of failures. Similarly, weak links in social and commercial networks can send waves of disruption through communities. Conversely, by understanding the positive impacts of interdependencies, spending can be targeted to maximize net social benefits while mitigating risks and improving economic development. Detailed information on public spending was not available for this study but case studies illustrate how networks of interdependent filters can modify

    The present Instruction Manual was prepared as part of a programme of the International Atomic Energy Agency to supply the international uranium community with standard guides for a number of topics related to uranium resource assessment and supply. The quantitative estimation of undiscovered resources and endowments aims at supplying data on potential mineral resources; these data are needed to compare long term projections with one another and to assess the mineral supplies to be obtained from elsewhere. These objectives have relatively recently been supplemented by the concern of land managers and national policy planners to assess the potential of certain lands before the constitution of national parks and other areas reserved from mineral exploration and development. 88 refs, 28 figs, 33 tabs

    The nature of energy and material resources in an endogenous growth theory framework is clarified. This involves three modifications of the conventional theory. Firstly, multiple feedback mechanisms or 'growth engines' are identified. Secondly, a production function distinguishes between resource use, technical efficiency and value creation. Thirdly, the impact of the cost of production through demand on growth is accounted for. A formal model is analytically solved under a condition of a constant growth rate. Given model complexity, numerical experiments are performed as well, providing relevant insights to the academic and political debates on 'environmental Kuznets curves' and 'dematerialization'. 49 refs.

    Nonsevere hypoglycemic events are common and may occur in one-third of persons with diabetes as often as several times a week. This study's objective was to examine the economic burden of nonsevere nocturnal hypoglycemic events (NSNHEs). A 20-minute Web-based survey, with items derived from the literature, expert input, and patient interviews, assessing the impact of NSNHEs was administered in nine countries to 18 years and older patients with self-reported diabetes having an NSNHE in the past month. A total of 20,212 persons were screened, with 2,108 respondents meeting criteria and included in the analysis sample. The cost of lost work productivity per NSNHE was estimated to be between $10.21 (Germany) and $28.13 (the United Kingdom), representing 3.3 to 7.5 hours of lost work time per event. A reduction in work productivity (presenteeism) was also reported. Compared with respondents' usual blood sugar monitoring practice, on average, 3.6 ± 6.6 extra tests were conducted in the week following the event at a cost of approximately $87.1 per year. Additional costs were also incurred for doctor visits as well as medical care required because of falls or injuries incurred during the NSNHE for an annual cost of $2,111.3 per person per year. When taking into consideration the multiple impacts of NSNHEs for the total sample and the frequency that these events occur, the resulting total annual economic burden was $288,000 or $127 per person per event. NSNHEs have serious consequences for patients. Greater attention to treatments that reduce NSNHEs can have a major impact on reducing the economic burden of diabetes.

  1. Economic potential of alternative land and natural resource uses at the Nevada Test Site, Nye County, Nevada

    International Nuclear Information System (INIS)

    Richard-Haggard, K.

    1983-03-01

    The economic potentials of several alternative land uses at the Nevada Test Site (NTS) are estimated. Alternatives considered include mining, agriculture, grazing, and hunting. There are two known tungsten ore bodies located in the Oak Spring mining district. The economic potential of the reserves is estimated to be $42,840. It is also possible that there are other economic mineral resources on the NTS whose values are yet unknown. There are an estimated 5000 ha of agricultural land on the Test Site; the cash value of alfalfa grown on this acreage is approximately $564,030. The economic potential of grazing at the Test Site lies somewhere in the range of $10,340 to $41,220. The assumed annual worth of mule deer to hunters is $90,440. The gross potential of hunting at the NTS is probably somewhat higher if trophy species, game birds and fur-bearing animals are also considered. It should be noted that the above values indicate gross worth; no costs are included in the estimates

  2. Advanced Burner Reactor with Breed-and-Burn Thorium Blankets for Improved Economics and Resource Utilization

    Energy Technology Data Exchange (ETDEWEB)

    Greenspan, Ehud [Univ. of California, Berkeley, CA (United States)

    2015-11-04

    This study assesses the feasibility of designing Seed and Blanket (S&B) Sodium-cooled Fast Reactor (SFR) to generate a significant fraction of the core power from radial thorium fueled blankets that operate on the Breed-and-Burn (B&B) mode without exceeding the radiation damage constraint of presently verified cladding materials. The S&B core is designed to maximize the fraction of neutrons that radially leak from the seed (or “driver”) into the subcritical blanket and reduce neutron loss via axial leakage. The blanket in the S&B core makes beneficial use of the leaking neutrons for improved economics and resource utilization. A specific objective of this study is to maximize the fraction of core power that can be generated by the blanket without violating the thermal hydraulic and material constraints. Since the blanket fuel requires no reprocessing along with remote fuel fabrication, a larger fraction of power from the blanket will result in a smaller fuel recycling capacity and lower fuel cycle cost per unit of electricity generated. A unique synergism is found between a low conversion ratio (CR) seed and a B&B blanket fueled by thorium. Among several benefits, this synergism enables the very low leakage S&B cores to have small positive coolant voiding reactivity coefficient and large enough negative Doppler coefficient even when using inert matrix fuel for the seed. The benefits of this synergism are maximized when using an annular seed surrounded by an inner and outer thorium blankets. Among the high-performance S&B cores designed to benefit from this unique synergism are: (1) the ultra-long cycle core that features a cycle length of ~7 years; (2) the high-transmutation rate core where the seed fuel features a TRU CR of 0.0. Its TRU transmutation rate is comparable to that of the reference Advanced Burner Reactor (ABR) with CR of 0.5 and the thorium blanket can generate close to 60% of the core power; but requires only one sixth of the reprocessing and

Strain selection and choice of conversion technology have large economic impacts, with differences between combinations of strains and biomass to biofuel technologies being up to $10 million dollars yr-1 UF-1. Results based on the most productive strain, HTL-based fuel conversion, and resource costs show that the economic potential between geographic locations within the selection can differ by up to $4 million yr-1 UF-1, with 1.8 BGY of production possible from the most cost-effective sites. The local spatial variability in site rank is extreme, with very high and low sites within 10s of km of each other. Colocation with flue gas sources has a strong influence on rank, but the most costly resource component varies from site to site. The highest rank UFs are located predominantly in Florida and Texas, but most states south of 37°N latitude contain promising locations.

    Presented here are the results of a techno-economic (TEA) study of the potential for coupling low-grade geothermal resources to boost the electrical output from coal-fired power plants. This study includes identification of candidate 500 MW subcritical coal-fired power plants in the continental United States, followed by down-selection and characterization of the North Valmy generating station, a Nevada coal-fired plant. Based on site and plant characteristics, ASPEN Plus models were designed to evaluate options to integrate geothermal resources directly into existing processes at North Valmy. Energy outputs and capital costing are presented for numerous hybrid strategies, including integration with Organic Rankine Cycles (ORCs), which currently represent the primary technology for baseload geothermal power generation.

  12. Characterizing China's energy consumption with selective economic factors and energy-resource endowment: a spatial econometric approach

    Science.gov (United States)

    Jiang, Lei; Ji, Minhe; Bai, Ling

    2015-06-01

    Coupled with intricate regional interactions, the provincial disparity of energy-resource endowment and other economic conditions in China have created spatially complex energy consumption patterns that require analyses beyond the traditional ones. To distill the spatial effect out of the resource and economic factors on China's energy consumption, this study recast the traditional econometric model in a spatial context. Several analytic steps were taken to reveal different aspects of the issue. Per capita energy consumption (AVEC) at the provincial level was first mapped to reveal spatial clusters of high energy consumption being located in either well developed or energy resourceful regions. This visual spatial autocorrelation pattern of AVEC was quantitatively tested to confirm its existence among Chinese provinces. A Moran scatterplot was employed to further display a relatively centralized trend occurring in those provinces that had parallel AVEC, revealing a spatial structure with attraction among high-high or low-low regions and repellency among high-low or low-high regions. By a comparison between the ordinary least square (OLS) model and its spatial econometric counterparts, a spatial error model (SEM) was selected to analyze the impact of major economic determinants on AVEC. While the analytic results revealed a significant positive correlation between AVEC and economic development, other determinants showed some intricate influential patterns. The provinces endowed with rich energy reserves were inclined to consume much more energy than those otherwise, whereas changing the economic structure by increasing the proportion of secondary and tertiary industries also tended to consume more energy. Both situations seem to underpin the fact that these provinces were largely trapped in the economies that were supported by technologies of low energy efficiency during the period, while other parts of the country were rapidly modernized by adopting advanced

    Decisions involving strain selection, biomass to biofuel technology, and the location of cultivation facilities can strongly influence the economic viability of an algae-based biofuel enterprise. In this contribution we summarize our past results in a new analysis to explore the relative economic impact of these design choices. We present strain-specific growth model results from two saline strains (Nannocloropsis salina, Arthrospira sp.), a fresh to brackish strain (Chlorella sp., DOE strain 1412), and a freshwater strain of the order Sphaeropleales. Biomass to biofuel conversion is compared between lipid extraction (LE) and hydrothermal liquefaction (HTL) technologies. National-scale models of water, CO2 (as flue gas), land acquisition, site leveling, construction of connecting roads, and transport of HTL oil to existing refineries are used in conjunction with estimates of fuel value (from HTL) to prioritize and select from 88,692 unit farms (UF, 405 ha in pond area), a number sufficient to produce 136E+9 L yr-1 of renewable diesel (36 billion gallons yr-1, BGY). Strain selection and choice of conversion technology have large economic impacts, with differences between combinations of strains and biomass to biofuel technologies being up to $10 million dollars yr-1 UF-1. Results based on the most productive species, HTL-based fuel conversion, and resource costs show that the economic potential between geographic locations within the selection can differ by up to $4 million yr-1 UF-1, with 2.0 BGY of production possible from the most cost-effective sites. The local spatial variability in site rank is extreme, with very high and low rank sites within 10s of km of each other. Colocation with flue gas sources has a strong influence on site rank, but the most costly resource component varies from site to site. The highest rank sites are located predominantly in Florida and Texas, but most states south of 37°N latitude contain promising locations. Keywords: algae

    A study will be conducted to evaluate non-electric applications of an identifiable geothermal energy resource in terms of engineering, economic, and institutional considerations and to formulate the preliminary design and implementation plan of the most promising demonstration or industrial development project. The purpose of this study is to determine potential options that the Energy Research and Development Administration may exercise in developing low- and moderate-temperature hydrothermal resources as an economically and environmentally acceptable alternate energy source and in enhancing the development of a coherent geothermal industry. The study will focus upon a reservoir-specific, multiple use application of hydrothermal resources underlying the City of Desert Hot Springs. Potential applications to be considered include a space conditioning utility network for commercial and residential buildings and an aquacultural and agricultural installation in individual as well as energy cascading systems. To extend the utility of the study findings, the evaluation of potential applications will be conducted within the wider context of satisfying broad regional needs. The study will also be conducted in the framework of a moving baseline to account for emerging technologies and possible future cost escalations and availability of alternate energy sources. The progress of this study will be monitored by an Advisory Board comprised of a representative cross-section of the geothermal community. Results of the study will be disseminated through reports and a workshop to maximize information exchange with the geothermal community. In addition, a self-start manual will be prepared and distributed so that interested communities having similar geothermal resources can readily evaluate appropriate nonelectric applications to meet their specific needs and gain added insight into how best to implement these applications.

    The ''entropy'' model for quantitative assessment of the impact of the electricity generating systems is discussed in the paper. Introduction of the ''entropy'' notion opens an opportunity to come to a new understanding of the competitiveness of the electricity generating technologies under taking into account not only economic but also environmental resources. The criterion of the effectiveness should be formulated as production the unit of electricity under minimal dissipation of human energy and natural resources or, in another words, under minimal increase of the 'nooentropy' in the production system. Under such wide definition, the effectiveness of a technology for electricity production becomes a very important index of the sustainability. The assessment of the ''nooentropy'' effectiveness of the main full-energy-chain electricity production options with normalization to natural resources of Russia has demonstrated important advantages of the nuclear power which are missed in another models of the system analysis, specifically, less impact on natural resource.

  16. Social, economic, and resource predictors of variability in household air pollution from cookstove emissions.

    Directory of Open Access Journals (Sweden)

    Gautam N Yadama

    Full Text Available We examine if social and economic factors, fuelwood availability, market and media access are associated with owning a modified stove and variation in household emissions from biomass combustion, a significant environmental and health concern in rural India. We analyze cross-sectional household socio-economic data, and PM(2.5 and particulate surface area concentration in household emissions from cookstoves (n=100. This data set combines household social and economic variables with particle emissions indexes associated with the household stove. The data are from the Foundation for Ecological Society, India, from a field study of household emissions. In our analysis, we find that less access to ready and free fuelwood and higher wealth are associated with owning a replacement/modified stove. We also find that additional kitchen ventilation is associated with a 12% reduction in particulate emissions concentration (p<0.05, after we account for the type of stove used. We did not find a significant association between replacement/modified stove on household emissions when controlling for additional ventilation. Higher wealth and education are associated with having additional ventilation. Social caste, market and media access did not have any effect on the presence of replacement or modified stoves or additional ventilation. While the data available to us does not allow an examination of direct health outcomes from emissions variations, adverse environmental and health impacts of toxic household emissions are well established elsewhere in the literature. The value of this study is in its further examination of the role of social and economic factors and available fuelwood from commons in type of stove use, and additional ventilation, and their effect on household emissions. These associations are important since the two direct routes to improving household air quality among the poor are stove type and better ventilation.

  17. From economics to resources: Teaching environmental sustainability in Peru's public education

    Adriazola-Rodriguez, Ana

    This dissertation examines the teaching of environmental awareness in Peru's public educational system and how it needs to be consciously taught and improved in order to overcome contamination and pollution of resources and decrease poverty. This is a situation afflicting a significant percentage of Peruvians, who face difficulty in surviving and living well because the scarcity of clean air and water, unpolluted land, and affordable energy, which are basic environmental resources. The teaching of environmental awareness, as mandated by Educational Peruvian Laws and curriculum, should be redesigned to promote environmental ethical awareness and sustainability to guard Peru's natural and cultural resources, bounty and beauty before it is too late. In this way, education will promote a better level of life for the majority of Peruvians. Peruvian public education is presently in a state of emergency, as has been recognized by the former minister of education Javier Sota Nadal (2004-2006). Only 10% of students leaving high school understand what they read and only 4% do well in mathematics. A number of reasons contribute to this tragedy. Among them is principally the low quality of teaching and the inadequate budget available for public education. Peru's laws, echoing the Universal Declaration of Human Rights, and mandate good and free education and guarantee the right to live well. The reality is that none of these rights are properly given to the majority of poor Peruvians. This dissertation offers a course of action to teach and spread out not only environmental awareness, but also environmental ethics and sustainability from a personal perspective. This rounded concept, if applied, will form citizens able to guard, protect, and preserve natural and cultural resources. The needed environmental ethics and sustainability education will gradually guarantee, from early in life, a truthful way to love, care, protect and preserve the ecosystem. Also encompassed within

    Full Text Available Ecosystem management is a recent alternative policy proposed by the Kosovo government to address a new generation of environmental issues. All Kosovo agency managements are currently exploring the concept of ecosystem management and their implications. Their activities are focused in the management of land and natural resources, by developing policy guidelines regarding the management of the ecosystem and the efforts undertaken that are only one layer of a larger phenomenon nationwide. Similar activities occur at the state and local levels, as well as within the NGO sector. In this sense, this paper addresses two questions: What is the policy of ecosystem management? Would Ecosystem management remain only a land management policy and resource?

    Full Text Available Qazvin plain is one of the capable plains in Iran to produce of agricultural goods. Unfortunately, due to inordinate shafts digging and irregular use of groundwater the level of groundwater has been decreased during two last decades so that water balance is negative now. To conserve the groundwater resources in this plain, strategies and appropriate policies are needed and this requires a better understanding of farmers’ behavior. Therefore, in the present study in order to investigate farmers' behavior in using of groundwater and determine appropriate strategies to conserve of groundwater resources in Qazvin plain, positive mathematical programming and production function with constant elasticity of substitution were used. The investigated strategies included increase in water price, decrease in water availability and deficit irrigation strategy and were investigated under various scenarios. The required data were registered information related to 2011-2012 collected from relevant departments in Qazvin province. The model was solved using GAMS 23/9 software. The results showed that all the investigated strategies led to water saving however the average gross profit changes decreased by 3.13, 8.61 and 5.54 percent with increasing water price, decrease in water availability and deficit irrigation, respectively. Finally, considering the less reduction in average gross profit, the irrigation water pricing and then deficit irrigation strategies were proposed to conserve groundwater resources in Qazvin plain.

    Faced with rising Third World nationalism, multinational corporations engaged in resource exploitation are turning back to higher-cost but apparently politically more-secure investments in the industrialized states. To what extent does the dynamic of government/resource industry relations in an industrialized setting differ from the pattern observed in the Third World. To answer this question the article analyses the decision to nationalize the potash industry in the Canadian province of Saskatchewan using models of host government--MNC conflict developed by Vernon, Mikesell, and Moran to study Third World cases. The research suggests that the dynamic logic of government/industry conflict in a developed country setting is very similar to the pattern observed in the Third World. The decentralized Canadian federation, the ideology of the party in power in Saskatchewan, and the nature of the potash industry combine to structure a situation in which coercive nationalization of a resource industry was seen as the only policy option. 64 notes and references.

    Full Text Available Climate projections agree on a dryer and warmer future for the Mediterranean. Consequently, the region is likely to face serious problems regarding water availability and quality in the future. We investigated potential climate change impacts, alone (for three scenario periods and in combination with four socio-economic scenarios (for the near future on water resources in a Mediterranean catchment, whose economy relies on irrigated agriculture and tourism. For that, the Soil and Water Integrated Model (SWIM was applied to the drainage area of the Mar Menor coastal lagoon, using a set of 15 climate scenarios and different land use maps and management settings. We assessed the long-term average seasonal and annual changes in generated runoff, groundwater recharge and actual evapotranspiration in the catchment, as well as on water inflow and nutrients input to the lagoon. The projected average annual changes in precipitation are small for the first scenario period, and so are the simulated impacts on all investigated components, on average. The negative trend of potential climate change impacts on water resources (i.e., decrease in all analyzed components becomes pronounced in the second and third scenario periods. The applied socio-economic scenarios intensify, reduce or even reverse the climate-induced impacts, depending on the assumed land use and management changes.

    During the past decade, the southern regions of the U.S. have experienced rapid change which is expected to continue into the foreseeable future. Growth in population, industry, and resource development has been attributed to a variety of advantages such as an abundant and inexpensive labor force, a mild climate, and the availability of energy, water, land, and other natural resources. While this growth has many benefits for the region, it also creates the potential for increased air, water, and solid waste pollution, and modification of natural habitats. A workshop was convened to consider the Mobile Bay area as a site-specific case of growth and its environmental consequences in the southern region. The objectives of the modeling workshop were to: (1) identify major factors of economic development as they relate to growth in the area over the immediate and longer term; (2) identify major environmental and resource management issues associated with this expected growth; and (3) identify and characterize the complex interrelationships among economic and environmental factors. This report summarizes the activities and results of a modeling workshop concerning economic growth and concomitant resource management issues in the Mobile Bay area. The workshop was organized around construction of a simulation model representing the relationships between a series of actions and indicators identified by participants. The workshop model had five major components. An Industry Submodel generated scenarios of growth in several industrial and transportation sectors. A Human Population/Economy Submodel calculated human population and economic variables in response to employment opportunities. A Land Use/Air Quality Submodel tabulated changes in land use, shoreline use, and air quality. A Water Submodel calculated indicators of water quality and quantity for fresh surface water, ground water, and Mobile Bay based on discharge information provided by the Industry and Human

    Diffusion of hydrogen as an energetic vector meets with a lot of obstacles that don't depend on available raw material, but on hydrogen combination with other elements. It is necessary, therefore, to separate hydrogen picking out the available different technologies to have different pure hydrogen of variable quantities. Besides, its diffusion as fuel is limited because of the great production cost compared to fuels sprung from petroleum. Hydrogen used on a large scale could have advantages on the environment and occupation, but there are economic and politic obstacles to limit its diffusion. Future of economic system, based on hydrogen as the main energetic vector, will depend on the programme that national and international qualified governing bodies will be able to do.

    2014-10-01

    Full Text Available Pressure on existing water resources in China is expected to increase with undergoing rapid demographic transformation, economic development, and global climate changes. We investigate the economy-wide impacts of projected urban population growth and economic structural change on water use and allocation in China. Using a multi-regional CGE (Computable General Equilibrium model, TERM (The Enormous Regional Model, we explore the implications of selected future water scenarios for China’s nine watershed regions. Our results indicate that urbanization and industrial transformation in China will raise the opportunity cost of water use and increase the competition for water between non-agricultural users and irrigation water users. The growth in water demand for domestic and industrial uses reduces the amount of water allocated to agriculture, particularly lower-value and water-intensive field crops. As a response, farmers have the incentive to shift their agricultural operations from traditional field crop production to higher-value livestock or intensive crop production. In addition, our results suggest that growing water demand due to urbanization and industrial transformation will raise the shadow price of water in all nine river basins. Finally, we find that national economic growth is largely attributable to urbanization and non-agricultural productivity growth.

    Full Text Available This study investigates the role of budget expenditure composition over Azerbaijan’s non-oil economic growth in the long-run by classifying public spending as capital, social and other expenditures. Authors’ employ ARDLBT approach to co-integration for the period of 2000Q1-2014Q4 to estimate long-run contribution of each spending category before-and-after the oil boom while controlling for oilrelated factors. Empirical results endorse the validity of long-run association among variables. Results concluded insignificant negative impact of capital expenditures, and significant negative impact of other expenditures. However, social spending has statistically and economically strong positive impact over the non-oil output growth. Therefore, research findings confirm that public expenditure composition significantly matters for long-run non-oil economic growth, and social expenditures have the greater positive impact in a resource-rich economy, Azerbaijan. Research results are highly useful for the government officials to consider while planning the expenditures in order to minimize negative response of non-oil sector to the fiscal contraction.

  11. Origins, characteristics, controls, and economic viabilities of deep- basin gas resources

    Science.gov (United States)

    Price, L.C.

    1995-01-01

    Dry-gas deposits (methane ???95% of the hydrocarbon (HC) gases) are thought to originate from in-reservoir thermal cracking of oil and C2+ HC gases to methane. However, because methanes from Anadarko Basin dry-gas deposits do not carry the isotopic signature characteristics of C15+ HC destruction, an origin of these methanes from this process is considered improbable. Instead, the isotopic signature of these methanes suggests that they were cogenerated with C15+ HC's. Only a limited resource of deep-basin gas deposits may be expected by the accepted model for the origin of dry-gas deposits because of a limited number of deep-basin oil deposits originally available to be thermally converted to dry gas. However, by the models of this paper (inefficient source-rock oil and gas expulsion, closed fluid systems in petroleum-basin depocenters, and most dry-gas methane cogenerated with C15+ HC's), very large, previously unrecognized, unconventional, deep-basin gas resources are expected. -from Author

    We report here on the development of an open source software framework termed CIM-EARTH that is intended to aid decision-making in climate and energy policy. Numerical modeling in support of evaluating policies to address climate change is difficult not only because of inherent uncertainties but because of the differences in scale and modeling approach required for various subcomponents of the system. Economic and climate models are structured quite differently, and while climate forcing can be assumed to be roughly global, climate impacts and the human response to them occur on small spatial scales. Mitigation policies likewise can be applied on scales ranging from the better part of a continent (e.g. a carbon cap-and-trade program for the entire U.S.) to a few hundred km (e.g. statewide renewable portfolio standards and local gasoline taxes). Both spatial and time resolution requirements can be challenging for global economic models. CIM-EARTH is a modular framework based around dynamic general equilibrium models. It is designed as a community tool that will enable study of the environmental benefits, transition costs, capitalization effects, and other consequences of both mitigation policies and unchecked climate change. Modularity enables both integration of highly resolved component sub-models for energy and other key systems and also user-directed choice of tradeoffs between e.g. spatial, sectoral, and time resolution. This poster describes the framework architecture, the current realized version, and plans for future releases. As with other open-source models familiar to the climate community (e.g. CCSM), deliverables will be made publicly available on a regular schedule, and community input is solicited for development of new features and modules.

  15. The German lignite industry. Historical development, resources, technology, economic structures and environmental impact. Study

    Lignite has a key role to play in the transformation of the energy system due to its specific structural features in terms of industry, company history, policy, economics, the environment and regional structures. Understanding these structural features of the German lignite industry is an important requirement for classifying the significance of the lignite industry up to now and for the redesigning of this industrial sector. From these environmental, economic and regulatory structural characteristics, which are interwoven in a variety of ways, the incentives arise for the mining and power plant operators to react to energy price signals or energy policy steering. The aim of this research study is to define these structural features, to compile comprehensively the basic data and information that is not always transparently available, to understand the interactions, to enable the navigation of issues that are partly very complex, and to classify into the long-term developments that are especially important for political and social processes. In 2016 approx. 12 percent of German primary energy consumption was met using lignite. At the same time, lignite has the highest carbon dioxide (CO2) emissions of the fossil fuels; it currently accounts for approx. 19 percent of Germany's total greenhouse gas emissions as well as approx. 46 percent of the total CO2 emissions of the electricity sector. As a result of the mining of lignite and its conversion into electricity, substantial adverse impacts beyond the entry of greenhouse gases into the Earth's atmosphere arise for other environmental media. These impacts include half of Germany's mercury emissions, approx. a third of its sulfur dioxide emissions and approx. a tenth of its nitrogen oxide emissions. Lignite mining in open-cast mines takes up a substantial amount of landscape and soil and requires huge interventions in the water balance. Relatively high costs arise for the recultivation and rehabilitation of the open

    Full Text Available Introduction: Agriculture as one of main axis of development in Iran is heavily depend on irrigation water. on the other hand, water resources have been under heavy pressure due to rising demand with different uses. Hence, water resources management and optimal water allocation have become increasingly important Undoubtedly, one of the most important tools for optimal allocation of water resources, is the economic valuation of the long-term development strategy of the country. However, the main question is whether the various agricultural policies of the government are to achieve self-sufficiency in the production decisions, in line with the management of water resources? Materials and Methods: To develop an analytical context for responding to above question, in this study, the effect of guaranteed purchase policy of wheat as one of the most supporting government policies, on the economic value of water resources in Orzoiyeh plain of Kerman province was studied. In order to achieve our goals, a dynamic mathematical programming model was used. A number of key questions are involved with the modeling of dynamic situations. Fundamentally, one must ask whether an explicit multiple time period representation is necessary. If so, a number of other questions are relevant. First, the length of the total time period and the starting date must be determined. Second, the length of the time intervals explicitly represented within the total time period must be determined. Third, initial and final inventory conditions must be specified. Fourth, one must decide on activity life, i.e., when a particular activity is begun and how long it lasts. Fifth, the rate of time preference must be determined, i.e., one needs the discount rate at which future returns are considered when compared with current returns. Sixth and finally, one must decide whether to include uncertainty. The sections below present discussion on each of these topics. Dynamic situations may not

    Decisions involving strain selection, biomass to biofuel technology, and the location of cultivation facilities can strongly influence the economic viability of an algae-based biofuel enterprise. We summarize our past results in a new analysis to explore the relative economic impact of these design choices. Our growth model is used to predict average biomass production for two saline strains (Nannochloropsis salina and Arthrospira sp.), one fresh to brackish strain (Chlorella sp., DOE strain 1412), and one freshwater strain (order Sphaeropleales). Biomass to biofuel conversion is compared between lipid extraction and hydrothermal liquefaction (HTL) technologies. National-scale models of water, CO{sub 2} (as flue gas), land acquisition, site leveling, construction of connecting roads, and transport of HTL oil to existing refineries are used in conjunction with estimates of fuel value (from HTL) to prioritize and select from 88,692 unit farms (UF, 405 ha in pond area), a number sufficient to produce 136E + 9 L year{sup −1} of renewable diesel [36 billion gallons year{sup −1} (BGY)]. Strain selection and choice of conversion technology have large economic impacts, with differences between combinations of strains and biomass to biofuel technologies being up to $10 million year{sup −1} UF{sup −1}. Results based on the most productive strain, HTL-based fuel conversion, and resource costs show that the economic potential between geographic locations within the selection can differ by up to 4 million year{sup −1} UF{sup −1}, with 1.8 BGY of production possible from the most cost-effective sites. The local spatial variability in site rank is extreme, with very high and low sites within 10 kms of each other. Colocation with flue gas sources has a strong influence on rank, but the most costly resource component varies from site to site. The highest rank UFs are located predominantly in Florida and Texas, but most states south of 37°N latitude contain promising

    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.

    Full Text Available The water industry is becoming increasingly aware of the risks associated with urban supplies not meeting demands by 2050. Greywater (GW recycling for non-potable uses (e.g., urinal and toilet flushing provides an urban water management strategy to help alleviate this risk by reducing main water demands. This paper proposes an innovative cross connected system that collects GW from residential buildings and recycles it for toilet/urinal flushing in both residential and office buildings. The capital cost (CAPEX, operational cost (OPEX and water saving potential are calculated for individual and shared residential and office buildings in an urban mixed-use regeneration area in the UK, assuming two different treatment processes; a membrane bioreactor (MBR and a vertical flow constructed wetland (VFCW. The Net Present Value (NPV method was used to compare the financial performance of each considered scenario, from where it was found that a shared GW recycling system (MBR was the most economically viable option. The sensitivity of this financial model was assessed, considering four parameters (i.e., water supply and sewerage charges, discount rate(s, service life and improved technological efficiency, e.g., low flush toilets, low shower heads, etc., from where it was found that shared GW systems performed best in the long-term.

    Full Text Available Afghanistan is a key country between energy surplus areas (Central Asian Republics andIran and energy deficit regions (Pakistan and India. It is in a position that can facilitate and launchregional electricity trade for the benefit of the region also derive significant gains for its own economyfrom energy imports and exports. On the other hand, Afghanistan is endowed with large renewableenergy resources (RERs, which it could exploit not only to satisfy its domestic power demand butalso to earn significant export revenue. This paper firstly explains the methodology and framework forthe power trade and then presents an optimization framework for profit maximization in the short-runtrading and cost minimization in the long-run trading. The proposed methodology is applied to a realcase between Afghanistan and Pakistan. The objective functions, parameters, variables and constraintsare described for both optimization models. System sizing, simulation and optimization are carriedout using genetic algorithm (GA technique. The results in the short-run model represent optimalityof about 2654 MW electricity export from Afghanistan to Pakistan during summer. Moreover, resultsderived from running long-run model depict that by utilizing its RERs such as solar, wind and hydro,Afghanistan can not only meet its power demand but also can export to Pakistan during its deficitperiods and gain remarkable energy profits.

    2015-12-01

    Full Text Available At the Rio “Earth Summit” the Convention on Biological Diversity introduced a global commitment to conservation of biological diversity and sustainable use of its components. An implementation process is going on, based on a strategic plan, biodiversity targets and a strategy for mobilizing financial resources. According to target “2”, by 2020 national accounts should include monetary aggregates related to biodiversity. Environmental accounts can play an important role – together with other information – in monitoring processes connected with target “20”: contribute to identifying activities needed to preserve biodiversity, calculating the associated costs and eventually assessing funding needs. In particular, EPEA and ReMEA are valuable accounting tools for providing data on biodiversity expenditure. The high quality of the information provided by these accounts makes them good candidates for being adopted world-wide within the Convention’s monitoring processes. Enhanced interaction between statisticians and officials from ministries of environment would be crucial to reach significant advancement towards standardization of the information used in support of the Convention.

    Full Text Available Significant strides have been made in the durability, portability, and safety of mechanical circulatory support devices (MCS. Although transplant is considered the standard treatment for advanced heart failure, limits in organ availability leave a much larger pool of recipients in need versus donors. MCS is used as bridge to transplantation and as destination therapy (DT for patients who will have MCS as their final invasive therapy with transplant not being an option. Despite improvements in quality of life (QOL and survival, defining the optimal candidate for DT may raise questions regarding the economics of this approach as well as ethical concerns regarding just distribution of goods and services. This paper highlights some of the key ethical issues related to justice and the costs of life-prolonging therapies with respect to resource allocations. Available literature, current debates, and future directions are discussed herein.

    Abstract Recent technical developments have made it possible to generate electricity from geothermal resources with low and medium enthalpy. One of these technologies is the Kalina Cycle System (KCS-34). In this study, electricity generation from Simav geothermal field is investigated. The optimum operating conditions for the KCS-34 plant design are determined on the basis of the exergetic and life-cycle-cost concepts. With the best design, power generation of 41.2 MW and electricity production of 346.1 GWh/a can be obtained with an energetic efficiency of 14.9% and exergetic efficiency of 36.2%. It is shown that, with the currently prevailing interest and inflation rates, the plant designs considered are economically feasible for values of the present worth factor (PWF) higher than 6.

    Considerable disease variability exists between patients with epilepsy, and the societal costs for epilepsy care are overall high, because of high frequency in the general population especially in children from developing countries. A cross-sectional study where children with established diagnosis of epilepsy were interviewed using a semi-structured questionnaire. Prevalence-based costs were stratified by patients' sociodemographic characteristics and socioeconomic scores (SES). The 'bottom-up' and 'human capital' approaches were used to generate estimates on the direct and indirect (productivity losses) costs of epilepsy, respectively. All estimates of the financial burden of epilepsy were analyzed from the 'societal perspective' using IBM SPSS statistics software, version 20.0. The study had 103 enrollees with most in the age group of 0-5years (45.6%). Majority (61.3%) belong to the low socioeconomic class (Ogunlesi SES class IV and V) and reside (80.6%) in an urban setting. The total direct and indirect costs per month were ₦2,149,965.00 ($8497.88) and ₦363,187.80 ($1435.52), respectively. The cost of care per patient per annum was ₦292,794.50 ($1157.29), and the total cost for all the patients per year was ₦30,157,833.60 ($119,200.92). Investigative procedures are the principal cost drivers (₦15,861.17 or $18.15) comprising approximately 58.7% of the total direct costs per patient. Cost of investigations contributed immensely to the total direct cost of care in our study. With the present economic situation in the country, out-of-pocket payments may contribute significantly to catastrophic expenditures and worsening of secondary treatment gap in children with epilepsy.

  8. Resource engineering and economic studies for direct application of geothermal energy. Draft final report

    Energy Technology Data Exchange (ETDEWEB)

    1981-12-01

    The feasibility of utilizing geothermal energy at a selected plant in New York State was studied. Existing oil and gas records suggests that geothermal fluid is available in the target area and based on this potential. Friendship Dairies, Inc., Friendship, NY, was selected as a potential user of geothermal energy. Currently natural gas and electricity are used as its primary energy sources. Six geothermal system configurations were analyzed based on replacement of gas or oil-fired systems for producing process heat. Each system was evaluated in terms of Internal Rate of Return on Investment (IRR), and simple payback. Six system configurations and two replaced fuels, representative of a range of situations found in the state, are analyzed. Based on the potential geothermal reserves at Friendship, each of the six system configurations are shown to be economically viable, compared to continued gas or oil-firing. The Computed IRR's are all far in excess of projected average interest rates for long term borrowings: approximately 15% for guarantee backed loans or as high as 20% for conventional financing. IRR is computed based on the total investment (equity plus debt) and cash flows before financing costs, i.e., before interest expense, but after the tax benefit of the interest deduction. The base case application for the Friendship analysis is case B/20 yr-gas which produces an IRR of 28.5% and payback of 3.4 years. Even better returns could be realized in the cases of oil-avoidance and where greater use of geothermal energy can be made as shown in the other cases considered.

    The main challenge of the BLUEPRINT to safeguard Europe's water resources (EC, 2012) is to guarantee that enough good quality water is available for people's needs, the economy and the environment. In this sense, economic policy instruments such as water pricing policies and water markets can be applied to enhance efficient use of water. This paper presents a method based on hydro-economic tools to assess the effect of economic instruments on water resource systems. Hydro-economic models allow integrated analysis of water supply, demand and infrastructure operation at the river basin scale, by simultaneously combining engineering, hydrologic and economic aspects of water resources management. The method made use of the simulation and optimization hydroeconomic tools SIMGAMS and OPTIGAMS. The simulation tool SIMGAMS allocates water resources among the users according to priorities and operating rules, and evaluate economic scarcity costs of the system by using economic demand functions. The model's objective function is designed so that the system aims to meet the operational targets (ranked according to priorities) at each month while following the system operating rules. The optimization tool OPTIGAMS allocates water resources based on an economic efficiency criterion: maximize net benefits, or alternatively, minimizing the total water scarcity and operating cost of water use. SIMGAS allows to simulate incentive water pricing policies based on marginal resource opportunity costs (MROC; Pulido-Velazquez et al., 2013). Storage-dependent step pricing functions are derived from the time series of MROC values at a certain reservoir in the system. These water pricing policies are defined based on water availability in the system (scarcity pricing), so that when water storage is high, the MROC is low, while low storage (drought periods) will be associated to high MROC and therefore, high prices. We also illustrate the use of OPTIGAMS to simulate the effect of ideal water

    This study has two objectives: (1) to examine healthcare resource utilization in heart failure (HF) patients; and (2) to examine the treatment costs associated with HF in China. The data used in this study was from the 2014 national insurance database sponsored by the China Health Insurance Research Association (CHIRA), that covers national urban employees and residents. ICD-10 codes and keywords indicating heart failure diagnoses were used to identify patients with heart failure. Drug utilization, hospital visits, re-admission, and treatment costs in different service categories were examined. A total of 7,847 patients were included in this analysis, of which 1,157 patients had a 1-year complete follow-up period. In total, 48.16% of patients received the combination treatment of angiotensin-converting-enzyme inhibitor (ACEI)/angiotensin II receptor blockers (ARB) and beta-blockers (BB); and 22.87% of patients received the combination treatment of ACEI/ARB, beta-blockers and Mineralocorticoid receptor antagonists (MRAs). The annual treatment cost per patient with HF diagnosis was RMB 28,974, of which 66% was for inpatient care. The cost on HF medications accounted for 8.2% of annual cost. Treatment cost was much higher in provincial-level municipalities than that of prefecture-level and other cities. Hospitalization is a major driver of HF treatment cost. Compared to the requirements in international treatment guidelines, HF standard of care medication treatment was under-utilized among HF patients in China. The high re-admission rate among Chinese patients indicates that the management of HF needs to be improved. The percentage of GDP spent on treating HF patients was much lower than that in the developed countries.

    Groundwater is often the most or only feasible safe drinking water source in remote, low-resource areas, yet the economics of its development have not been systematically outlined. We applied AWARE (Assessing Water Alternatives in Remote Economies), a recently developed Decision Support System, to investigate the costs and benefits of groundwater access and abstraction for non-networked, rural supplies. Synthetic profiles of community water services (n = 17,962), defined across 13 parameters' values and ranges relevant to remote areas, were applied to the decision framework, and the parameter effects on economic outcomes were investigated. Regressions and analysis of output distributions indicate that the most important factors determining the cost of water improvements include the technological approach, the water service target, hydrological parameters, and population density. New source construction is less cost-effective than the use or improvement of existing wells, but necessary for expanding access to isolated households. We also explored three financing approaches - willingness-to-pay, -borrow, and -work - and found that they significantly impact the prospects of achieving demand-driven cost recovery. The net benefit under willingness to work, in which water infrastructure is coupled to community irrigation and cash payments replaced by labor commitments, is impacted most strongly by groundwater yield and managerial factors. These findings suggest that the cost-benefit dynamics of groundwater-based water supply improvements vary considerably by many parameters, and that the relative strengths of different development strategies may be leveraged for achieving optimal outcomes.

    Water resources across the world have been increasingly stressed in the past few decades due to the population and economic growth and climate change. Consequently, the competing use of water among agricultural, domestic and industrial sectors is expected to be increasing. In this study, the water stresses under various climate change, socio-economic development and irrigation management scenarios are predicted over the period of 2015-2050 using an integrated model, in which the changes in water supply and demand induced by climate change, socio-economic development and irrigation management are dynamically parameterized. Simulations on the case of Texas, Southwest U.S. were performed using the newly developed integrated model, showing that the water stress is projected to be elevated in 2050 over most areas of Texas, particularly at Northern and Southern Plain and metropolitan areas. Climate change represents the most pronounce factor affecting the water supply and irrigation water demand in Texas. The water supply over East Texas is largely reduced in future because of the less precipitation and higher temperature under the climate change scenario, resulting in an elevated irrigation water demand and thus a higher water stress in this region. In contrast, the severity of water shortage in West Texas would be alleviated in future because of climate change. The water shortage index over metropolitan areas would increase by 50-90% under 1.0% migration scenario, suggesting that the population growth in future could also greatly stress the water supply, especially megacities like Dallas, Houston, Austin and San Antonio. The projected increase in manufacturing water demand shows little effects on the water stress. Increasing irrigation rate exacerbates the water stress over irrigated agricultural areas of Texas.

    Depletion of fossil fuel resources and the gradual increase in cost of their extraction and transportation to the places of their consumption put forward into a line of the most urgent tasks the problem of rational and economical utilization of fuel and energy resources, as well as introduction of new energy sources into various sectors of the national economy. The nuclear energy sources which are widely spread in power engineering have not yet been used to a proper extent in the sectors of industrial technologies and residential space heating, which are the most energy consuming sectors in the national economy. The most effective way of solving this problem can be the development and commercialization of high temperature nuclear reactors, as the majority of power consuming industrial processes and those involved in chemico-thermal systems of distant heat transmission demand the temperature of a heat carrier generated by nuclear reactors and assimilated by the above processes to be in the range from 900 0 to 1000 0 C.

    SummaryMineral commodities are vital for economic growth, improving the quality of life, providing for national defense, and the overall functioning of modern society. Minerals are being used in larger quantities than ever before and in an increasingly diverse range of applications. With the increasing demand for a considerably more diverse suite of mineral commodities has come renewed recognition that competition and conflict over mineral resources can pose significant risks to the manufacturing industries that depend on them. In addition, production of many mineral commodities has become concentrated in relatively few countries (for example, tungsten, rare-earth elements, and antimony in China; niobium in Brazil; and platinum-group elements in South Africa and Russia), thus increasing the risk for supply disruption owing to political, social, or other factors. At the same time, an increasing awareness of and sensitivity to potential environmental and health issues caused by the mining and processing of many mineral commodities may place additional restrictions on mineral supplies. These factors have led a number of Governments, including the Government of the United States, to attempt to identify those mineral commodities that are viewed as most “critical” to the national economy and (or) security if supplies should be curtailed.This book presents resource and geologic information on the following 23 mineral commodities currently among those viewed as important to the national economy and national security of the United States: antimony (Sb), barite (barium, Ba), beryllium (Be), cobalt (Co), fluorite or fluorspar (fluorine, F), gallium (Ga), germanium (Ge), graphite (carbon, C), hafnium (Hf), indium (In), lithium (Li), manganese (Mn), niobium (Nb), platinum-group elements (PGE), rare-earth elements (REE), rhenium (Re), selenium (Se), tantalum (Ta), tellurium (Te), tin (Sn), titanium (Ti), vanadium (V), and zirconium (Zr). For a number of these commodities

    Approximately 85 percent of the land area of the ECOWAS (Economic Community of West African States) region is covered by basement rocks (igneous and highly metamorphosed rocks) or relatively thin layers of Paleozoic, Upper Precambrian, and Continental Intercalaire sedimentary rocks. These areas have little or no petroleum potential. The ECOWAS region can be divided into 13 sedimentary basins on the basis of analysis of the geologic framework of Africa. These 13 basins can be further grouped into 8 categories on the basis of similarities in stratigraphy, geologic history, and probable hydrocarbon potential. The author has attempted to summarize the petroleum potential within the geologic framework of the region. The coal discoveries can be summarized as follows: the Carboniferous section in the Niger Basin; the Paleocene-Maestrichtian, Maestrichtian, and Eocene sections in the Niger Delta and Benin; the Maestrichtian section in the Senegal Basin; and the Pleistocene section in Sierra Leone. The only proved commercial deposits are the Paleocene-Maestrichtian and Maestrichtian subbituminous coal beds of the Niger Delta. Some of the lignite deposits of the Niger Delta and Senegal Basin, however, may be exploitable in the future. Published literature contains limited data on heat-flow values in the ECOWAS region. It is inferred, however, from the few values available and the regional geology that the development of geothermal resources, in general, would be uneconomical. Exceptions may include a geopressured zone in the Niger Delta and areas of recent tectonic activity in the Benue Trough and Cameroon. Development of the latter areas under present economic conditions is not feasible.

    Fall injuries among people aged 65 years and over (older people) cause substantial health decline and cost to the health system. In 2009 in New South Wales, 25.6% of older people fell in the previous year, and 10.7% (32 000) were hospitalised. Pharmacists are trusted professionals, who interact extensively with older people and have potential to augment fall prevention in pharmacies. This brief report describes how professional development improved pharmacist's knowledge and confidence in fall prevention, encouraged implementation of fall prevention plans and facilitated the provision of brief fall prevention interventions for older clients, after identification of fall risk. In 2014, pharmacists from all Central Coast pharmacies (n = 76) were invited to free, continuing professional development (CPD) in fall prevention. It provided education and resources to identify clients' fall risk, conduct brief fall prevention interventions and implement fall prevention health promotion plans (FPHPP). Pharmacists completed written: Baseline and post-workshop questionnaires to assess changes in pharmacist's knowledge and confidence, and existing fall prevention in pharmacies. Logs of client fall risk and brief fall prevention interventions offered to clients. Four-month follow-up questionnaires to assess implementation of FPHPPs and pharmacy practice changes. Pharmacists representing 36% of pharmacies participated. At four-month follow-up, 67% had implemented FPHPPs, and 62% delivered brief interventions determined by client fall risk. Fall prevention in pharmacies can be augmented through locally provided CPD tailored for pharmacists. SO WHAT?: This model could increase fall prevention reach. It is transferable to settings where health professionals provide services to older adults and require reregistration through professional development. © 2018 Australian Health Promotion Association.

    A case study of an 89-year-old patient is reported, who was admitted to hospital because of immobility due to pain. After the cause of the pain could initially be clarified and treated, the further clinical course in this very old woman showed an alarming symptom complex of agitation, confusion and cognitive deterioration, which took on grave forms. The work-up of this case showed a typical constellation of pain and depression in old age; however, the pharmaceutical treatment in this case is not atypical and could lead to a severe serotonin syndrome. The interaction, diagnostics, differential diagnosis, pharmacological, functional, codification and economic aspects of the course of the disease are discussed.

  18. ‘Yet even the dogs eat the crumbs that fall from their masters’ table’: Matthew’s Gospel and economic globalisation

    Directory of Open Access Journals (Sweden)

    Lidija Novakovic

    2009-11-01

    Full Text Available One of the effects of economic globalisation is that it strengthens the superiority of the developed and intensifies the dependency of the undeveloped nations. Christian ethicists typically address this problem by emphasising the need for social justice and the ethics of love expressed through sharing and generosity. This article offers another contribution to this discussion – an analysis of the subversive understanding of power and identity that underlies the story of Jesus in Matthew’s narrative. It concludes that Matthew’s Gospel offers a message of encouragement and accountability. It encourages the underprivileged to work for a change of conventional hierarchies that favour the privileged and calls them to actively participate in the creation of just relationships. At the same time, it reminds those who manage to improve their conditions that they should be transformed by the grace shown to them and strive for righteousness that exceeds the ethical standards of their former superiors.

  19. An analysis of the economic impact of non-pipeline options for developing Newfoundland's offshore natural gas resources

    Locke, W.; Millan, S.; Rodgers, B.

    2001-06-01

    The technical and economic feasibility of four non-pipeline development options for Newfoundland's offshore natural gas resources are examined. The options are: compressed natural gas (CNG) that is incremental to FPSO oil development (CNG FPSO Incremental); CNG as part of a Grand Bank System Gas Hub( CNG GBS Gas Hub); liquefied natural gas (LNG) that is incremental to FPSO oil development (LNG FPSO Incremental) and combined Fischer-Tropsch (gas-to-liquid technology) that is incremental to FPSO oil development (combined methanol/F-T). The economic impacts of each development option were considered in terms of project viability, employment and income impacts created through the supply of goods and services, employment effects resulting from project expenditures, incomes generated to Newfoundland factors of production, GDP impacts, and provincial treasury impacts, net of equalization losses. Results indicate that the largest employment and income impacts on the Newfoundland economy would be generated by the CNG GBS Gas Hub option (2,000 person-years of employment per year and $110 million income annually). The other three cases provide an equivalent level of benefits with an annual average of 1,650 person-years of employment and $90 million in incomes to business and labour. Each option is expected to generate between $16 and $21 million per annum to the Newfoundland treasury, net of equalization losses. GDP impacts are also close for all all four options, and provide no basis for preference of any option. In terms of project viability, the CNG FPSO Incremental option is considered by far the most attractive with a 33.7 per cent rate of return and a net present value of $1 billion, followed by the CNG GBS Gas Hub option at 18.3 per cent rate of return and a net present value of $317 million. The LNG FPSO incremental option has an internal rate of return of 17.8 per cent and a net present value of $263 million. The combined methanol/F-T option is not considered

    1993-12-31

    Natural resource economics issues deal with flows and funds of renewable and nonrenewable resources over time. These issues include topics concerned with management of fisheries, forests, mineral, energy resources, the extinction of species and the irreversibility of development over time. Environmental economics issues deal with regulation of polluting activities and the valuation of environmental amenities. In this study we outline a framework for studying both natural resource and environmental economics issues for any renewable or nonrenewable resource. Valuation from both the cost and benefit sides are addressed as they relate to the valuation of environmental programs or policies. By using this top-down approach to analyze and determine the costs and benefits of using renewable or nonrenewable resources, policy-makers on the global, national and local scales may be better informed as to the probable nonmarket and market ramifications of their natural resource and environmental policy decisions. This general framework for analysis is then focused to address biomass energy crops and their usage as inputs to energy production. As with any energy technology, a complete analysis must include an examination of the entire fuel cycle; specifically both production and consumption sides. From a production standpoint, market valuation issues such as crop management techniques, inputs to production, and community economics issues must be addressed as well as nonmarket valuation issues such as soil erosion, ground water effects and carbon sequestration. On the consumption side, market valuation considerations such as energy fuel efficiency and quality, cost of conversion and employment of labor are important factors while the critical nonmarket valuation factors are ambient air visibility, greenhouse gas release, and disposal of the by-products of conversion and combustion.

    2010-03-01

    Outpatient non-attendance is a considerable source of inefficiency in the health service, wasting time, resources and potentially lengthening waiting lists, Given the current economic climate, methods need to be employed to reduce non-attendance. The aim was to analyse outpatient non-attendance and determine what factors influence attendance. A prospective audit over a two-month period to a tertiary-referral Urological service was performed to determine the clinical and demographic profile of non-attendees. Of 737 appointments, 148 (20%) patients did not attend (DNA). A benign urological condition was evident in 116 cases (78%). This group of patients also accounted for the majority of new patients not attending 40\\/47, returning patients not attending 101\\/148 and the majority of patients who missed multiple appointments 43\\/49. Patients with benign conditions make up the majority of clinic non-attendance. Consideration may be given to discharging such patients back to their general practitioner after one unexplained non-attendance until other alternatives of follow up are available.

  4. Using non-renewable resources to promote economic development: The case of stock-dependent extraction cost

    International Nuclear Information System (INIS)

    Jefferson, R.W.

    1991-01-01

    Various policies for using a newly discovered deposit of a non-renewable resource to promote local economic development are considered. A model of optimal extraction, in which cost depends on both current output and remaining stock levels is constructed. The model is simplified by the assumptions that prices are exogenous and that extraction cost is linear homogeneous in current output and remaining stock. Both pure depletion and combined extraction and exploration models are considered. The models are solved using the dynamic programming algorithm. The effects of taxes on profit and gross revenue are analyzed both algebraically and through numerical simulations. The conditions under which a tax on profit does not distort production are specified. The welfare costs of tax-induced distortions in extraction and exploration are discussed using simulation results. The effects on production of future prices being stochastic are discussed, and it is shown that a firm which re-optimizes each period on the basis of new information concerning that period's price will choose to restrict output below that which would have been optimal if the expected price could be forecast with certainty

  5. Stimulating fuelwood consumption through public policies: An assessment of economic and resource impacts based on the French Forest Sector Model

    2013-01-01

    Stimulating renewable energy is a crucial objective in view of tackling climate change and coping with future fossil fuel scarcity. In France, fuelwood appears to be an important source for the renewable energy mix. Using the French Forest Sector Model, our paper aims to assess the impacts of three policy options to stimulate fuelwood consumption: a consumer subsidy, a producer subsidy and a fixed-demand contract policy. We explored their impacts in terms of five groups of criteria: (1) forest resource dynamics; (2) variations in wood products prices and quantities consumed and produced; (3) trade balance; (4) budgetary costs; and (5) variations in agent surpluses. We show that no policy option is more desirable than another on the basis of all of these criteria and that trade-offs will determine which is the best policy option to be implemented. - Highlights: • We compare the bio-economic impacts of policies to boost fuelwood consumption in France. • We simulate a producer subsidy, a consumer subsidy and fixed public demand contracts. • We explore their impacts until 2020 with a dynamic model of the forest sector. • Producer subsidy reduces the trade balance deficit and decreases forest stock. • Consumer subsidy increases consumer welfare and public contracts reduce budgetary costs

  6. Scale Issues in Modeling the Water Resources Sector in National Economic Models: A Case study of China

    2001-05-01

    The fundamental theme of this research was to investigate tradeoffs in model resolution for modeling water resources in the context of national economic development and capital investment decisions.. Based on a case study of China, the research team has developed water resource models at relatively fine scales, then investigated how they can be aggregated to regional or national scales and for use in national level planning decisions or global scale integrated assessment models of food and/or environmental change issues. The team has developed regional water supply and water demand functions.. Simplifying and aggregating the supply and demand functions will allow reduced form functions of the water sector for inclusion in large scale national economic models. Water Supply Cost functions were developed looking at both surface and groundwater supplies. Surface Water: Long time series of flows at the mouths of the 36 major river sub-basins in China are used in conjunction with different basin reservoir storage quantities to obtain storage-yield curves. These are then combined with reservoir and transmission cost data to obtain yield-cost or surface water demand curves. The methodology to obtain the long time series of flows for each basin is to fit a simple abcd water balance model to each basin. The costs of reservoir storage have been estimated by using a methodology developed in the USA that relates marginal storage costs to existing storage, slope and geological conditions. USA costs functions have then been adjusted to Chinese costs. The costs of some actual dams in China were used to "ground-truth" the methodology. Groundwater: The purpose of the groundwater work is to estimate the recharge in each basin, and the depths and quality of water of aquifers. A byproduct of the application of the abcd water balance model is the recharge. Depths and quality of aquifers are being taken from many separate reports on groundwater in different parts of China; we have been

    This report is a release of digital data and associated survey descriptions from a series of magnetic resonance soundings (MRS, also known as surface nuclear magnetic resonance) that was conducted during October and November of 2012 in areas of western Nebraska as part of a cooperative hydrologic study by the North Platte Natural Resource District (NRD), South Platte NRD, Twin Platte NRD, the Nebraska Environmental Trust, and the U.S. Geological Survey (USGS). The objective of the study was to delineate the base-of-aquifer and refine the understanding of the hydrologic properties in the aquifer system. The MRS technique non-invasively measures water content in the subsurface, which makes it a useful tool for hydrologic investigations in the near surface (up to depths of approximately 150 meters). In total, 14 MRS production-level soundings were acquired by the USGS over an area of approximately 10,600 square kilometers. The data are presented here in digital format, along with acquisition information, survey and site descriptions, and metadata.

    Full Text Available The Changchun–Jilin Economic Zone (CJEZ is one of the most rapidly developing areas in Northeast China, as well as one of the famous golden maize belts in the world. This is a case study to assess the impacts of urban sprawl on soil resources using remote sensing imagery and geographic spatial analysis methods. The common urbanization intensity index (CUII, soil quality index, and soil landscape metrics were calculated to reflect urbanization and the response of soil resource. Results showed that the area of soil sealing changed from 112,460 ha in 2000 to 139,233 ha in 2015, and in the rural region, the area occupied by urbanization nearly kept balance with the area of rural residential expansion. Urban land increased by 26,767 ha at an annual rate of 3.23% from 2000 to 2015. All seven soil types were occupied during the urbanization process, among which black soil ranked the highest (18,560 ha and accounted for 69.34% of the total occupied area. Soils of Grades I (3927 ha and II (15,016 ha were 64.75% of the total occupied soil areas. Urban land expanded in an irregular shape and a disordered way, which led to an increasing large patch index (LPI and aggregation index (AI, and a decreasing edge density (ED and Shannon’s diversity index (SHDI of the soil landscape in the study area during 2000–2015. According to the geographically weighted regression (GWR model analysis, the R2 between the CUII and soil landscape metrics decreased from the LPI and ED to SHDI and in turn to AI. The local R2 between SHDI, ED, and CUII showed a gradient structure from the inner city to peri-urban areas, in which larger values appeared with strongly intensive urbanization in urban fringes. Soil sealing induced by urbanization has become a significant factor threatening soil, the environment, and food security. How to coordinate regional development and ensure the sustainability of the multiple functions of soil is a problem that needs to be taken into account

    2012-04-01

    We investigate the regional economic consequences of a hypothetical catastrophic event-attack via radiological dispersal device (RDD)-centered on the downtown Los Angeles area. We distinguish two routes via which such an event might affect regional economic activity: (i) reduction in effective resource supply (the resource loss effect) and (ii) shifts in the perceptions of economic agents (the behavioral effect). The resource loss effect relates to the physical destructiveness of the event, while the behavioral effect relates to changes in fear and risk perception. Both affect the size of the regional economy. RDD detonation causes little capital damage and few casualties, but generates substantial short-run resource loss via business interruption. Changes in fear and risk perception increase the supply cost of resources to the affected region, while simultaneously reducing demand for goods produced in the region. We use results from a nationwide survey, tailored to our RDD scenario, to inform our model values for behavioral effects. Survey results, supplemented by findings from previous research on stigmatized asset values, suggest that in the region affected by the RDD, households may require higher wages, investors may require higher returns, and customers may require price discounts. We show that because behavioral effects may have lingering long-term deleterious impacts on both the supply-cost of resources to a region and willingness to pay for regional output, they can generate changes in regional gross domestic product (GDP) much greater than those generated by resource loss effects. Implications for policies that have the potential to mitigate these effects are discussed. © 2011 Society for Risk Analysis.

  12. Environmental, economic, social and political drivers for increasing use of woodfuel as a renewable resource in Britain

    International Nuclear Information System (INIS)

    McKay, Helen

    2006-01-01

    Present woodfuel usage in Britain is negligible. Historically, Britain has been fortunate in having abundant coal, oil and gas. At an EU level, biomass is seen as an important element of energy, environment and agriculture/forestry policy. In the European context, biomass is taken to include agricultural and industrial wastes in addition to forest woodfuel, and it is regarded as a potential source of heat, fuels and electricity. In the UK, energy policy as a whole is based on four considerations-environment, energy reliability and security, affordability for the poorest in society and competitive pricing for businesses, industries and households. Within UK policy, the dominant driver for greater use of biomass as a renewable source of energy is climate change mitigation; energy security is an emerging driver; all other potential benefits of biomass as a renewable resource are of limited significance. At the moment, the UK focus is narrower than in Europe. National targets are set only for electricity generation. Furthermore, expansion of energy crops, which are defined in the major regulations as 'crops planted since 1989 and grown primarily for the purpose of being used as a fuel' and, therefore, do not include material from extant forests, is seen as the main way to ensure energy security and minimise carbon expended to transport the raw material to the point of end use. Nevertheless, woody biomass from forests, sawmills, urban areas and transportation corridors is already available in vastly greater quantities than 'energy crops'. At a regional and local scale, global environmental issues are of lower relative importance and a much wider range of potential benefits tend to be taken into consideration. For example, the economic benefits of woodfuel heating in areas without connections to the gas grid have been an important consideration in the steady increase in woodheat developments. In other areas where there is a less obvious financial driver, rural

    Industrial ecology is the epitome of sustainable development in industry level, is one effective gateway to realizing green transformation. On the basis of industrial ecology development, including resource efficiency and environmental efficiency of ecological evaluation index system, this paper evaluates the level of industrial ecology development of resource-based industries in Xinjiang using entropy method. Research shows that the overall ecological development level of resource-based industries has remained at continuous improved trend with slow improvement in resource efficiency, and relative faster improvement in environmental efficiency. With economic development entering into the period of new normal at the end of the “twelfth five year plan”, the resource efficiency of ecological development of resource-based industries demonstrated a downward trend. The overall level of industrial ecology also faced with certain fluctuations, various ecological development level of resource-based industries also presented a downward trend. To promote ecological development of resource-based industries in Xinjiang, countermeasures and suggestions are initiated.

    2015-05-01

    Microalgae biofuel production has been extensively evaluated through resource, economic and life cycle assessments. Resource assessments consistently identify land as non-limiting and highlight the need to consider siting based on combined geographical constraints of land and other critical resources such as water and carbon dioxide. Economic assessments report a selling cost of fuel that ranges between $1.64 and over $30 gal(-1) consistent with large variability reported in the life cycle literature, -75 to 534 gCO2-eq MJ(-1). Large drivers behind such variability stem from differences in productivity assumptions, pathway technologies, and system boundaries. Productivity represents foundational units in these assessments with current assumed yields in various assessments varying by a factor of 60. A review of the literature in these areas highlights the need for harmonized assessments such that direct comparisons of alternative processing technologies can be made on the metrics of resource requirements, economic feasibility, and environmental impact.

    The Bio-based Raw Materials Platform (PGG), part of the Energy Transition in The Netherlands, commissioned the Agricultural Economics Research Institute (LEI) and the Copernicus Institute of Utrecht University to conduct research on the macro-economic impact of large scale deployment of biomass for energy and materials in the Netherlands. Two model approaches were applied based on a consistent set of scenario assumptions: a bottom-up study including technoeconomic projections of fossil and bio-based conversion technologies and a topdown study including macro-economic modelling of (global) trade of biomass and fossil resources. The results of the top-down and bottom-up modelling work are reported separately. The results of the synthesis of the modelling work are presented in the main report. This report (part 1) presents scenarios for future biomass use for energy and materials, and analyses the consequences on energy supply, chemical productions, costs and greenhouse gas (GHG) emissions with a bottom-up approach. The bottom-up projections, as presented in this report, form the basis for modelling work using the top-down macro-economic model (LEITAP) to assess the economic impact of substituting fossil-based energy carriers with biomass in the Netherlands. The results of the macro-economic modelling work, and the linkage between the results of the bottom-up and top-down work, will be presented in the top-down economic part and synthesis report of this study

    2014-09-01

    Accidental falls are the leading cause of injury-related death and hospitalization in old age, with over one-third of the older adults experiencing at least one fall or more each year. Because of limited healthcare resources, regular objective fall risk assessments are not possible in the community on a large scale. New methods for fall prediction are necessary to identify and monitor those older people at high risk of falling who would benefit from participating in falls prevention programmes. Technological advances have enabled less expensive ways to quantify physical fall risk in clinical practice and in the homes of older people. Recently, several studies have demonstrated that sensor-based fall risk assessments of postural sway, functional mobility, stepping and walking can discriminate between fallers and nonfallers. Recent research has used low-cost, portable and objective measuring instruments to assess fall risk in older people. Future use of these technologies holds promise for assessing fall risk accurately in an unobtrusive manner in clinical and daily life settings.

    Potential economic benefits obtainable from a state-of-the-art ERS system in the resource area of intensive use of living resources, agriculture, are studied. A spectrum of equal capability (cost saving), increased capability, and new capability benefits are quantified. These benefits are estimated via ECON developed models of the agricultural marketplace and include benefits of improved production and distribution of agricultural crops. It is shown that increased capability benefits and new capability benefits result from a reduction of losses due to disease and insect infestation given ERS's capability to distinguish crop vigor and from the improvement in world trade negotiations given ERS's worldwide surveying capability.

  18. Do economic evaluation studies inform effective healthcare resource allocation in Iran? A critical review of the literature

    Science.gov (United States)

    2014-01-01

    To aid informed health sector decision-making, data from sufficient high quality economic evaluations must be available to policy makers. To date, no known study has analysed the quantity and quality of available Iranian economic evaluation studies. This study aimed to assess the quantity, quality and targeting of economic evaluation studies conducted in the Iranian context. The study systematically reviewed full economic evaluation studies (n = 30) published between 1999 and 2012 in international and local journals. The findings of the review indicate that although the literature on economic evaluation in Iran is growing, these evaluations were of poor quality and suffer from several major methodological flaws. Furthermore, the review reveals that economic evaluation studies have not addressed the major health problems in Iran. While the availability of evidence is no guarantee that it will be used to aid decision-making, the absence of evidence will certainly preclude its use. Considering the deficiencies in the data identified by this review, current economic evaluations cannot be a useful source of information for decision makers in Iran. To improve the quality and overall usefulness of economic evaluations we would recommend; 1) developing clear national guidelines for the conduct of economic evaluations, 2) highlighting priority areas where information from such studies would be most useful and 3) training researchers and policy makers in the calculation and use of economic evaluation data.

    One of four persons over age 65 in the community falls; those over age 75 in institutions fall more frequently. Falls, a complex phenomena suggesting present disease and predicting future disability, are caused by interactions between the environment and dynamic balance which is determined by the quality of sensory input, central processing, and motor responses. Clinical factors which predispose to falling often produce observable disturbances in gait and balance, making observation critical in assessment. Acute illness and drug therapy produce particularly preventable falls. Therapeutic exercise and environmental modification for safety are the clinical interventions most likely to successfully prevent fall-related injury.

    To examine incidence, associated factors, and health care provider (HCP) response to falls in persons with multiple sclerosis (MS). Cross-sectional retrospective design. Community setting. Four hundred seventy-four persons with MS. Mailed survey questionnaire examined incidence, risk factors, and HCP response to falls in persons with MS who were dwelling in the community. Univariate and multiple ordinal regression analysis identified variables associated with single and multiple falls. Falls, causes and perceived reasons for falls, and HCP response. A total of 265 participants (58.2%) reported one or more falls in the previous 6 months, and 58.5% of falls were medically injurious. Trips/slips while walking accounted for 48% of falls. Factors associated with falls included use of a cane or walker (odds ratio [OR] 2.62; 95% confidence interval [CI] 1.66-4.14), income falls; recommended strategies included safety strategies (53.2%), use of gait assistive devices (42.1%), exercise/balance training (22.2%), and home modifications (16.6%). Factors associated with falls in persons with MS are similar to those in other populations with neurologic diseases. Despite the high incidence of falls, fewer than 50% of people with MS receive information about prevention of falls from an HCP.

    The purpose of this study was to review the evidence of the economic burden of falls in old age. This review showed that falls are a relevant economic burden. Efforts should be directed to fall-prevention programmes. Falls are a common mechanism of injury and a leading cause of costs of injury in the elderly. The purpose of this study was to review for the first time the evidence of the economic burden caused by falls in old age. A systematic review was conducted in the databases of PubMed, of the Centre for Reviews and Dissemination and in the Cochrane Database of Systematic Reviews until June 2009. Studies were assessed for inclusion, classified and synthesised. Costs per inhabitant, the share of fall-related costs in total health care expenditures and in gross domestic products (GDP) were calculated. If appropriate, cost data were inflated to the year 2006 and converted to US Dollar (USD PPP). A total of 32 studies were included. National fall-related costs of prevalence-based studies were between 0.85% and 1.5% of the total health care expenditures, 0.07% to 0.20% of the GDP and ranged from 113 to 547 USD PPP per inhabitant. Direct costs occurred especially in higher age groups, in females, in hospitals and long-term care facilities and for fractures. Mean costs per fall victim, per fall and per fall-related hospitalisation ranged from 2,044 to 25,955; 1,059 to 10,913 and 5,654 to 42,840 USD PPP and depended on fall severity. A more detailed comparison is restricted by the limited number of studies. Falls are a relevant economic burden to society. Efforts should be directed to economic evaluations of fall-prevention programmes aiming at reducing fall-related fractures, which contribute substantially to fall-related costs.

    Full Text Available The article is aimed at studying the influence of the population’s savings and the financial resources of enterprises on the socio-economic development of the regions of Ukraine. Conditions for stabilizing and improving the socio-economic level of development of regions were considered, based on the multiplying influence of savings through transformation of them into capital investments through the network chain of «gross regional product – population income – spending – taxes – savings – capital investment – gross regional product». The thesis that the multiplying effect of savings of population manifests and fosters the economic growth on the assumption that the savings provide the formation of capital investments, aimed at the growth of the gross regional product, has been substantiated.

    The Bio-based Raw Materials Platform (PGG), part of the Energy Transition in The Netherlands, commissioned the Agricultural Economics Research Institute (LEI) and the Copernicus Institute of Utrecht University to conduct research on the macro-economic impact of large scale deployment of biomass for energy and materials in the Netherlands. Two model approaches were applied based on a consistent set of scenario assumptions: a bottom-up study including technoeconomic projections of fossil and bio-based conversion technologies and a topdown study including macro-economic modelling of (global) trade of biomass and fossil resources. The results of the top-down and bottom-up modelling work are reported separately. This is the public version of studies [nl

  12. Falls and falls efficacy: the role of sustained attention in older adults

    LENUS (Irish Health Repository)

    2011-12-19

    Abstract Background Previous evidence indicates that older people allocate more of their attentional resources toward their gait and that the attention-related changes that occur during aging increase the risk of falls. The aim of this study was to investigate whether performance and variability in sustained attention is associated with falls and falls efficacy in older adults. Methods 458 community-dwelling adults aged ≥ 60 years underwent a comprehensive geriatric assessment. Mean and variability of reaction time (RT), commission errors and omission errors were recorded during a fixed version of the Sustained Attention to Response Task (SART). RT variability was decomposed using the Fast Fourier Transform (FFT) procedure, to help characterise variability associated with the arousal and vigilance aspects of sustained attention. The number of self-reported falls in the previous twelve months, and falls efficacy (Modified Falls Efficacy Scale) were also recorded. Results Significant increases in the mean and variability of reaction time on the SART were significantly associated with both falls (p < 0.01) and reduced falls efficacy (p < 0.05) in older adults. An increase in omission errors was also associated with falls (p < 0.01) and reduced falls efficacy (p < 0.05). Upon controlling for age and gender affects, logistic regression modelling revealed that increasing variability associated with the vigilance (top-down) aspect of sustained attention was a retrospective predictor of falling (p < 0.01, OR = 1.14, 95% CI: 1.03 - 1.26) in the previous year and was weakly correlated with reduced falls efficacy in non-fallers (p = 0.07). Conclusions Greater variability in sustained attention is strongly correlated with retrospective falls and to a lesser degree with reduced falls efficacy. This cognitive measure may provide a novel and valuable biomarker for falls in older adults, potentially allowing for early detection and the implementation of preventative intervention

This paper used statistical T test method for Chinese provincial economic development test combined with China's regional development strategy analysis after a brief theoretical review, and finally it established a Chinese provincial panel data econometric model for empirical study. This paper also uses different estimation methods, including Pooled OLS, GLS estimates and GMM, to estimate the model and found that variation of coefficient of the OLS estimation and the GMM estimation are small, this implies that the model has a good stability and the estimation results are reliable. Had the initial economic level controlled, it founded that China had the "resource curse" phenomenon based on the energy resources but not on mineral resources. This

    Falls are a common cause of serious injury and injury-related death in the older adult population, and may be associated with multiple risks such as age, history of falls, impaired mobility, balance and gait problems, and medications. Sensory and environmental factors as well as the fear of falling may also increase the risk of falls. The purpose of this article is to review current best practice on screening fall risks and fear of falling, fall prevention strategies, and fall prevention resources to assist gerontological nurses in reducing falls by their older adult clients.

    2010-01-01

    Despite differences in their implementation, most carbon policies aim to have similar outcomes: effectively raising the price of carbon-intensive products relative to non-carbon-intensive products. While it is possible to predict the simple broad-scale economic impacts of raising the price of carbon-intensive products-the demand for non-carbon-intensive products will increase-understanding the economic and environmental impacts of carbon policies throughout the life cycle of both types of products is more difficult. Using the example of a carbon tax, this study proposes a methodology that integrates short-term policy-induced consumer demand changes into the input-output framework to analyze the environmental and economic repercussions of a policy. Environmental repercussions include the direct and the indirect impacts on emissions, materials flow in the economy, and the reliance on various ecosystem goods and services. The approach combines economic data with data about physical flow of fossil fuels between sectors, consumption of natural resources and emissions from each sector. It applies several input-output modeling equations sequentially and uses various levels of aggregation/disaggregation. It is illustrated with the data for the 2002 U.S. economy and physical flows. The framework provides insight into the short-term complex interactions between carbon price and its economic and environmental effects.

  1. Osteosarcopenic obesity and fall prevention strategies.

    Hita-Contreras, Fidel; Martínez-Amat, Antonio; Cruz-Díaz, David; Pérez-López, Faustino R

    2015-02-01

    Sarcopenia, obesity, and osteoporosis are three interrelated entities which may share common pathophysiological factors. In the last decades, overall survival has drastically increased. Postmenopausal women, due to their estrogen depletion, are at higher risk of developing any of these three conditions or the three, which is termed osteosarcopenic obesity. One of the most common health problems among these patients is the elevated risk of falls and fractures. Falls and fall-related injuries are one of the major causes of mortality and morbidity in older adults, and have a significant impact on social, economical and health-related costs. Several extrinsic and intrinsic risk factors have been described that play a role in the etiology of falls. A therapeutic approach to osteosarcopenic obesity aimed at the prevention of falls must include several factors, and act on those risk elements which can be effectively modified. An adequate weight-loss diet and a good nutritional intake, with an appropriate amount of vitamin D and the right protein/carbohydrates ratio, may contribute to the prevention of falls. The recommendation of physical exercise, both traditional (resistance or aerobic training) and more recent varieties (Tai Chi, Pilates, body vibration), can improve balance and positively contribute to fall prevention, whether by itself or in combination with other therapeutic strategies. Finally, a pharmacological approach, especially one focused on hormone therapy, has shown to have a positive effect on postmenopausal women's balance, leading to a decreased risk of falls.

    Full Text Available Groundwater is an important resource that meets part or all of the water demand in many developed basins. Since it is an integral part of the hydrologic cycle, management of groundwater resources must consider not only the management of surface flows but also the variability in climate. In addition, agricultural and urban activities both affect the availability of water resources and are affected by it. Arguably, the Central Valley of the State of California, USA, can be considered a basin where all stresses that can possibly affect the management of groundwater resources seem to have come together: a vibrant economy that depends on water, a relatively dry climate, a disparity between water demand and availability both in time and space, heavily managed stream flows that are susceptible to water quality issues and sea level rise, degradation of aquifer conditions due to over-pumping, and degradation of the environment with multiple species becoming endangered. Over the past fifteen years, the California Department of Water Resources has developed and maintained the Integrated Water Flow Model (IWFM to aid in groundwater management and planning under complex, and often competing, requirements. This paper will describe features of IWFM as a generic modeling tool, and showcase several of its innovative applications within California.

    The study of meteorites provides insight into the earliest history of our solar system. From 1800, about the year meteorites were first recognized as objects falling from the sky, until December 2014, 158 observed meteorite falls were recorded in Africa. Their collected mass ranges from 1.4 g to 175 kg with the 1-10 kg cases predominant. The average rate of African falls is low with only one fall recovery per 1.35-year time interval (or 0.023 per year per million km2). This African collection is dominated by ordinary chondrites (78%) just like in the worldwide falls. The seventeen achondrites include three Martian meteorite falls (Nakhla of Egypt, Tissint of Morocco and Zagami of Nigeria). Observed Iron meteorite falls are relatively rare and represent only 5%. The falls' rate in Africa is variable in time and in space. The number of falls continues to grow since 1860, 80% of which were recovered during the period between 1910 and 2014. Most of these documented meteorite falls have been recovered from North-Western Africa, Eastern Africa and Southern Africa. They are concentrated in countries which have a large surface area and a large population with a uniform distribution. Other factors are also favorable for observing and collecting meteorite falls across the African territory, such as: a genuine meteorite education, a semi-arid to arid climate (clear sky throughout the year most of the time), croplands or sparse grasslands and possible access to the fall location with a low percentage of forest cover and dense road network.

    Essential facts Falls are the most frequent adverse event reported in hospitals, usually affecting older patients. Every year, more than 240,000 falls are reported in acute hospitals and mental health trusts in England and Wales, equivalent to more than 600 a day, according to the Royal College of Physicians (RCP). But research shows that when nurses, doctors and therapists work together, falls can be reduced by 20-30%.

    The nature of energy and material resources in a non-optimizing growth theory framework is clarified. This involves two modifications of the conventional theory. Firstly, multiple feedback mechanisms or 'growth engines' are identified, such that the impact of the cost of production through demand on growth is accounted for. Secondly, a production function distinguishes between resource use, technical efficiency, and value creation. The resulting model is analytically solved under the condition of a constant growth rate. Given model complexity, numerical experiments are performed as well, providing relevant insights to the academic and political debates on 'environmental Kuznets curves' and 'dematerialization.'.

    2014-03-01

    Full Text Available The Brazilian government has recently confirmed the discovery of a huge oil and natural gas field in the pre-salt layer of the country’s southeastern coast. It has been said that the oil fields can boost Brazil’s oil production and turn the country into one of the largest oil producers in the world. The fields are spatially concentrated in the coastal areas of a few Brazilian states that may directly benefit from oil production. This paper uses an interregional computable general equilibrium model to assess the impacts of pre-salt on the economy of the State of Espírito Santo, a region already characterized by an economic base that is heavily reliant on natural resources. We focus our analysis on the structural economic impacts on the local economy

    Youth demonstrate a low propensity to seek help for mental health issues and exhibit low use of health services despite the high prevalence of mental health challenges in this population. Research has found that delivering interventions via the internet and mobile devices is an effective way to reach youth. Thought Spot, a Web- and mobile-based map, was developed to help transition-aged youth in postsecondary settings overcome barriers to help-seeking, thereby reducing the economic burden associated with untreated mental health issues. This paper presents the protocol for an economic evaluation that will be conducted in conjunction with a randomized controlled trial (RCT) to evaluate the effectiveness and cost of Thought Spot compared with usual care in terms of self-efficacy for mental health help-seeking among postsecondary students. A partially blinded RCT will be conducted to assess the impact of Thought Spot on the self-efficacy of students for mental health help-seeking. Students from 3 postsecondary institutions in Ontario, Canada will be randomly allocated to 1 of 2 intervention groups (resource pamphlet or Thought Spot) for 6 months. The economic evaluation will focus on the perspective of postsecondary institutions or other organizations interested in using Thought Spot. Costs and resources for operating and maintaining the platform will be reported and compared with the costs and resource needs associated with usual care. The primary outcome will be change in help-seeking intentions, measured using the General Help-Seeking Questionnaire. The cost-effectiveness of the intervention will be determined by calculating the incremental cost-effectiveness ratio, which will then be compared with willingness to pay. The RCT is scheduled to begin in February 2018 and will run for 6 months, after which the economic evaluation will be completed. We expect to demonstrate that Thought Spot is a cost-effective way to improve help-seeking intentions and encourage help

    To assess the feasibility and value of simulating whole disease and treatment pathways within a single model to provide a common economic basis for informing resource allocation decisions. A patient-level simulation model was developed with the intention of being capable of evaluating multiple topics within National Institute for Health and Clinical Excellence's colorectal cancer clinical guideline. The model simulates disease and treatment pathways from preclinical disease through to detection, diagnosis, adjuvant/neoadjuvant treatments, follow-up, curative/palliative treatments for metastases, supportive care, and eventual death. The model parameters were informed by meta-analyses, randomized trials, observational studies, health utility studies, audit data, costing sources, and expert opinion. Unobservable natural history parameters were calibrated against external data using Bayesian Markov chain Monte Carlo methods. Economic analysis was undertaken using conventional cost-utility decision rules within each guideline topic and constrained maximization rules across multiple topics. Under usual processes for guideline development, piecewise economic modeling would have been used to evaluate between one and three topics. The Whole Disease Model was capable of evaluating 11 of 15 guideline topics, ranging from alternative diagnostic technologies through to treatments for metastatic disease. The constrained maximization analysis identified a configuration of colorectal services that is expected to maximize quality-adjusted life-year gains without exceeding current expenditure levels. This study indicates that Whole Disease Model development is feasible and can allow for the economic analysis of most interventions across a disease service within a consistent conceptual and mathematical infrastructure. This disease-level modeling approach may be of particular value in providing an economic basis to support other clinical guidelines. Copyright © 2013 International

  19. Macro-economic impact of large-scale deployment of biomass resources for energy and materials on a national level—A combined approach for the Netherlands

    2013-01-01

    Biomass is considered one of the most important options in the transition to a sustainable energy system with reduced greenhouse gas (GHG) emissions and increased security of enegry supply. In order to facilitate this transition with targeted policies and implementation strategies, it is of vital importance to understand the economic benefits, uncertainties and risks of this transition. This article presents a quantification of the economic impacts on value added, employment shares and the trade balance as well as required biomass and avoided primary energy and greenhouse gases related to large scale biomass deployment on a country level (the Netherlands) for different future scenarios to 2030. This is done by using the macro-economic computable general equilibrium (CGE) model LEITAP, capable of quantifying direct and indirect effects of a bio-based economy combined with a spread sheet tool to address underlying technological details. Although the combined approach has limitations, the results of the projections show that substitution of fossil energy carriers by biomass, could have positive economic effects, as well as reducing GHG emissions and fossil energy requirement. Key factors to achieve these targets are enhanced technological development and the import of sustainable biomass resources to the Netherlands. - Highlights: • We analyse large scale production of bioenergy and biochemicals in the Netherlands. • The scenarios include up to 30% substitution of fossil fuels by biomass in 2030. • Resulting in strong greenhouse gas savings and positive macro-economic effects. • Large amounts of imported biomass are required to meet the domestic demand. • This requires high rates of technological change and strict sustainability criteria

  20. The Fall in Older Adults: Physical and Cognitive Problems.

    2017-01-01

    The aging of posture and balance function alters the quality of life in older people and causes serious problems in terms of public health and socio-economic costs for our modern societies. This article reviews the various causes of imbalance and dizziness in the elderly, and considers how to prevent falls, and how to rehabilitate a faller subject in order to regain a good quality of life. Two effective ways of intervention are discussed, emphasizing the crucial role of physical activity and cognitive stimulation, classic or using the latest technical advances in virtual reality and video games. Fall in the elderly result from aging mechanisms acting on both the sensorimotor and cognitive spheres. The structural and functional integrity of the peripheral sensory receptors and the musculoskeletal system deteriorate with age. The brain ages and the executive functions, memory, learning, cortical processing of information, sharing of attentional resources and concentration, are modified in the elderly. Psychological affective factors such as depression, anxiety and stress contribute also to speed up the sensorimotor and cognitive decline. The rehabilitation of the postural balance in the elderly must take into account all of these components. The aging of the population and the increased of lifespan are a challenge for our modern societies regarding the major health and socio-economic questions they raise. The fall in the elderly being one of the dramatic consequences of the aging equilibration function, it is therefore imperative to develop rehabilitation procedures of balance.

    Water is essential for life and ecological sustenance; its availability is essential component of national welfare and productivity.The country's socio-economic activities are largely dependent on the natural endowment of water resources. Kenya's water resources comprises of surface waters (rivers, lakes and wetlands) and ground water. Surface water forms 86% of total water resources while the rest is ground water Geological, topographical and climatic factors influence the natural availability and distribution of water with the rainfall distribution having the major influence. Water resources in Kenya are continuously under threat of depletion and quality degradation owing to rising population, industrialization, changing land use and settlement activities as well as natural changes. However, the anticipated climate change is likely to exacerbate the situation resulting in increased conflict over water use rights in particular, and, natural resource utilisation in general. The impacts of climate change on the water resources would lead to other impacts on environmental and socio-economic systems

    Full Text Available A laboratory based microflotation rig termed efficient FLOtation of Algae Technology (eFLOAT was used to optimise parameters for harvesting microalgal biomass from eutrophic water systems. This was performed for the dual objectives of remediation (nutrient removal and resource recovery. Preliminary experiments demonstrated that chitosan was more efficient than alum for flocculation of biomass and the presence of bacteria could play a positive role and reduce flocculant application rates under the natural conditions tested. Maximum biomass removal from a hyper-eutrophic water retention pond sample was achieved with 5 mg·L−1 chitosan (90% Chlorophyll a removal. Harvesting at maximum rates showed that after 10 days, the bacterial diversity is significantly increased with reduced cyanobacteria, indicating improved ecosystem functioning. The resource potential within the biomass was characterized by 9.02 μg phosphate, 0.36 mg protein, and 103.7 μg lipid per mg of biomass. Fatty acid methyl ester composition was comparable to pure cultures of microalgae, dominated by C16 and C18 chain lengths with saturated, monounsaturated, and polyunsaturated fatty acids. Finally, the laboratory data was translated into a full-size and modular eFLOAT system, with estimated costs as a novel eco-technology for efficient algal bloom harvesting.

    Full Text Available Water resource and environment capacity have become two of the most important restrictions for sustainable development in resource-based cities whose leading industries are the exploitation and processing of resources. Taking Ordos in China as an example, this article constructs an integrated model combining a multi-objective optimization model with input–output analysis to achieve the tradeoffs between economic growth, water utilization and environmental protection. This dynamic model includes socioeconomic, water supply–demand, water quality control, air quality control, energy consumption control and integrated policy sub-models. These six sub-models interact with each other. After simulation, this article proposes efficient solutions on industrial restructuring by maximizing the Gross Regional Product of Ordos from 394.3 in 2012 to 785.1 billion RMB in 2025 with a growth rate of 6.4% annually; and presents a water supply plan by maximizing the proportion of reclaimed water from 2% to 6.3% through sewage treatment technology selection and introduction, and effective water allocation. Meanwhile, the environmental impacts are all in line with the planning targets. This study illustrates that the integrated modeling is generic and can be applied to any region suffering uncoordinated development issues and can serve as a pre-evaluation approach for conducting early warning research to offer suggestions for government decision-making.

    This study presents the techno-economic evaluation of 2,3-butanediol (BDO) production via fermentation using glycerol, sucrose and sugarcane molasses as carbon sources. Literature-cited experimental data were used to design the fermentation stage, whereas downstream separation of BDO was based on reactive extraction of BDO employing an aldehyde to convert BDO into an acetal that is immiscible with water. The selected downstream process can be used in all fermentations employed. Sensitivity analysis was carried out targeting the estimation of the minimum selling price (MSP) of BDO at different plant capacities and raw material purchase costs. In all cases, the MSP of BDO is higher than 1 $/kg that is considered as the target in order to characterize a fermentation product as platform chemical. The complex nutrient supplements, the raw material market price and the fermentation efficiency were identified as the major reasons for the relatively high MSP observed.

    As mobile robots are used in more uncertain and dangerous environments, it will become important to design them so that they can survive falls. In this paper, we examine a number of mechanisms and strategies that animals use to withstand these potentially catastrophic events and extend them to the design of robots. A brief survey of several aspects of how common cats survive falls provides an understanding of the issues involved in preventing traumatic injury during a falling event. After outlining situations in which robots might fall, a number of factors affecting their survival are described. From this background, several robot design guidelines are derived. These include recommendations for the physical structure of the robot as well as requirements for the robot control architecture. A control architecture is proposed based on reactive control techniques and action-oriented perception that is geared to support this form of survival behavior.

    Interactions between societies and nature are regulated by complex systems of beliefs, symbolism, customs, and worldviews (kosmos), ecological knowledge (corpus), and management strategies and practices (praxis), which are constructed as product of experiences and communication of people throughout time. These aspects influence social relations, life strategies, and cultural identity, and all of them in turn influence and are influenced by local and regional patterns of interchange. In this study, we analyze the interchange of wild and weedy plants and mushrooms in traditional markets of the Phurépecha region of Mexico. Particularly, the social relations constructed around the interchange of these products; how knowledge, cultural values, and ecological factors influence and are influenced by interchange; and how all these factors influence the type and intensity of biotic resources management. We studied three main traditional markets of the Phurépecha region of Michoacán, Mexico, through 140 visits to markets and 60 semi-structured interviews to sellers of wild and weedy plants and mushrooms. In nearly 2 years, we carried out 80 visits and 30 interviews in the "Barter Market", 20 visits and 15 interviews in the "Phurépecha Tiánguis", and 40 visits and 15 interviews to the "Municipal Market". We documented information about the spaces of interchange that form the markets, the types of interchange occurring there, the cultural and economic values of the resources studied, the environmental units that are sources of such resources, the activities associated to resources harvesting and, particularly, the management techniques practiced to ensure or increase their availability. We analyzed the relations between the amounts of products interchanged, considered as pressures on the resources; the perception of their abundance or scarcity, considered as the magnitude of risk in relation to the pressures referred to; and the management types as response to pressures

    Wind energy is amongst the fastest growing sources of renewable energy in the U.S. and could supply up to 20 % of the U.S power production by 2030. An accurate and reliable wind resource assessment for prospective wind farm sites is a challenging task, yet is crucial for evaluating the long-term profitability and feasibility of a potential development. We have developed an accurate and computationally efficient wind resource assessment technique for prospective wind farm sites, which incorporates innovative statistical techniques and the new NASA Earth science dataset MERRA. This technique produces a wind resource estimate that is more accurate than that obtained by the wind energy industry's standard technique, while providing a reliable quantification of its uncertainty. The focus now is on evaluating the socio-economic value of this new technique upon using the industry's standard technique. Would it yield lower financing costs? Could it result in lower electricity prices? Are there further down-the-line positive consequences, e.g. job creation, time saved, greenhouse gas decrease? Ultimately, we expect our results will inform efforts to refine and disseminate the new technique to support the development of the U.S. renewable energy infrastructure. In order to address the above questions, we are carrying out a cost-benefit analysis based on the net present worth of the technique. We will describe this approach, including the cash-flow process of wind farm financing, how the wind resource assessment factors in, and will present current results for various hypothetical candidate wind farm sites.

    Socio-economic resources may be associated with infant feeding in complex patterns in societies undergoing a nutrition transition. This study evaluates associations of housing quality, food security and maternal education to the World Health Organization (WHO) feeding recommendations and to consumption of highly processed snacks (HP snacks) and sugar-sweetened beverages (SSBs) in rural Nicaragua. Data were collected from May to November 2009, with mothers of 0- to 35-month-olds being asked about young child feeding using a food frequency questionnaire. A validated questionnaire was used to assess household food insecurity and data were collected on maternal education and housing quality. Pearson's chi-squared test was used to compare proportions and determine associations between the resources and young child feeding. The three socio-economic resources and other confounders were introduced to multivariate logistic regression analyses to assess the independent contribution of the resources to the feeding practices and consumption of HP snacks and SSBs. Mothers with the lowest education level were more likely to be exclusively breastfeeding (EBF) their infants (OR not EBF: 0.19; 95% CI: 0.07, 0.51), whilst mothers of 6- to 35-month-olds in the lowest education category had more inadequate dietary diversity (DD) (OR for not meet DD: 2.04; 95% CI: 1.36, 3.08), were less likely to consume HP snacks (OR for HP snacks: 0.47; 95% CI: 0.32, 0.68) and SSBs (OR for SSBs: 0.68; 95% CI: 0.46, 0.98), compared to mothers with the highest level of education. Similarly, children residing in households with the highest food insecurity were also more prone to have inadequate dietary diversity (OR for not meet DD: 1.47; 95% CI: 1.05, 2.05). The odds for double burden of suboptimal feeding (concurrent inadequate diet and consumption of HP snacks/SSBs) were significantly lower in children of least educated mothers (OR: 0.64; 95% CI: 0.44, 0.92). Higher level of education was associated

    Full Text Available Diversity of mangrove function generates both tangible and intangible benefits and services causing its overall value is not easily recognized hence often overlooked in coastal areas development. The study used the total economic value as a framework for estimating the values of the different uses of mangroves in East Sinjai Sub District, South Sulawesi. Survey method was carried out from September 2014 February 2015. The results showed that − total value of mangrove ecosystems in East Sinjai with total area of ​​758 ha is IDR37,535,809,496 year . Those v -1 alues were derived from direct benefits (polyculture fish pond, catching aquatic biota such as fish, shrimp, crab and milkfish, collecting fuelwood and bats catching and from indirect benefits i.e. its function to evade abrasion and sea water intrusion, its function as carbon sink and sequestration, its biodiversity values ​​and its existence benefits. The problem that should be anticipated is potential expansion of polyculture fishpond which drives clearing intact mangrove forests as it contributes quick and direct income to local people. The research results are expected could be used as a consideration in formulating for sustainable for local government recommendations mangrove management in East Sinjai.

    This paper reviews institutional changes in pastureland use in China over the last 30 years and discusses their impacts on pastoral communities, drawing evidence from case studies of two agro-pastoralist and two pastoralist communities. Those who rely directly on pastureland for their livelihood are vulnerable to the joint effects of pastureland degradation and climate change. The authors argue that a 'top-down' governance structure with no participation from local communities and a 'one size fits all' institutional solution are a poor fit for pastoralism management. The authors conclude that the current institutional environment in China may be leading to decreasing populations, reduced livestock rearing, impoverishment and increasing inequality within pastoral communities. Bearing in mind that pastoral systems have characteristics that are specific to their areas and tailored to their local context, the authors recommend paying greater attention to 'bottom-up', locally specified strategies which can be combined with long-term institutional arrangements that have historically provided pastoralists and agro-pastoralists with the resources to adapt to change.

    Based on relation of resource allocation and marginal benefit of e-commence provider, both of origin and essence of the 3Q e-business fight were analyzed; and then contents of the contract between e-business company and users were elaborated. Moreover, liability for Qihoo's breach of the contract in 3Q e-business fight was discussed. Analysis of the contract indicated that blame of infringing on privacy of users from public, media or even a law professor for Tengxun Company is not exactly justicial. Some controversial rules which are not fit for usual practices in the QQ contract such as narrow definition of privacy were found out, whose reason lies in no relevant e-business standards or rules in our country. In the end, this passage points out that actions of government who intervened in market operations of Tengxun Company and QQ Company are inappropriate and unnecessary. Thus, responsibility for facing up to incomplete market rules of e-commence lies with government and government should strengthen market supervision by legislation so as to guide healthy development of e-business market, which is a key lesson we learn from the 3Q e-business fight.

    Full Text Available Uttar Pradesh, one of the most populated states of India along international border of Nepal, contributes only about 3% of total forest & tree cover of the country as the major parts of the area is covered by agriculture lands and human populations. The forests are quite fragmented and facing severe anthropogenic pressure in many parts. To protect the existing biodiversity, several forest covers have been declared as National Parks and Wildlife Sanctuaries. In the present study, Katerniaghat Wildlife Sanctuary (KWS has been selected to assess tree diversity, their phenology and economic values as the trees are the major constituent of any forest and more fascinating among all plant groups. The sanctuary consists of tropical moist deciduous type of vegetation and situated along the Indo-Nepal boarder in Bahraich district of Uttar Pradesh, India. After, thorough assessment of the area, a list of 141 tree species belonging to 101 genera and 38 families have been prepared. The family Fabaceae exhibits highest generic and species diversity with 14 genera and 23 species. The genus Ficus of Moraceae has been found the largest with 11 species. Maximum trees with about 51 species have been found to flower in post winter season (February to March in the forest. About 62 trees are used as medicinal for various purposes, 50 as ornamental & avenue trees, 37 as timber wood, 36 as edible, 16 as fire wood and 12 as fodder. Since the sanctuary area has been surrounded by several villages and facing anthropogenic pressure, the public awareness program related with biodiversity conservation and sustainable uses is highly needed to protect the forest covers.

To date, there is no information about how this trend will behave over the next few years. The aim of the present study is to define a pharmacoeconomic model for the forecast of the costs of a group of chronically treated patients followed over the period 2004–2009.Methods: A pharmacoeconomics model was built to describe the probability of transition among different health states and to modify the therapy over time. A Markov model was applied to evaluate the temporal evolution of the average cost. The health care resources exploited during hospitalization were analyzed by using an “activity-based costing” method.Results: The Markov model showed that the mean total cost, after an initial increase, tended to remain stable. A total of 20 clinical records were examined. The average daily cost for each patient was EUR 484.42, with a cost for admission of EUR 6781.88.Conclusion: The treatment of HIV infection in compliance with the guidelines is also effective from the payer perspective, as it allows a good health condition to be maintained and reduces the need and the costs of hospitalizations.Keywords: health care cost, HIV, Markov model, activity-based costing

  19. Is mortality after childhood cancer dependent on social or economic resources of parents? A population-based study.

    Diagnostic and treatment protocols for childhood cancer are generally standardized, and therefore, survival ought to be fairly equal across social strata in societies with free public health care readily available. Nevertheless, our study explores whether there are disparities in mortality after childhood cancer in Norway depending on socioeconomic status of parents. Limited knowledge on differentials exists from earlier analyses. Discrete-time hazard regression models for all-cause mortality for the first 10 years after diagnosis were estimated for all Norwegian children (younger than 20 years), who were diagnosed with cancer during 1974-2007 (N = 6,280), using data from five national registers. Mortality was reduced by about 15% for children with highly educated mothers and children without siblings. These effects were most pronounced for cancers predicted to encompass intense, long-lasting treatments resulting in chronic health problems. Neither earnings nor the marital status of parents affected children's survival. This large, registry-based study suggests that time constraints and various noneconomic rewards of parents from their education appears to have an impact on childhood cancer survival. It may be that children with resourceful parents are healthier at the outset and/or are more likely to avoid later health problems. It may also be that children of well-informed and strongly involved parents are offered better treatment or are able to make better use of what is offered, for instance, by adhering more closely to recommendations for follow-up treatment. The possibility of such differentials in offered and actual treatment should be addressed in future research. Copyright © 2011 UICC.

    With the geological-economic evaluation program for pithead heap-leaching mining uranium deposits developed by the authors and the data of column-leaching tests and the geological reserve, the geological-economic evaluation is made to the residual geological reserves of both Lujing and Huangfengling deposit, and the geological reserves of Yangjiaonao deposit of the depleted mines in Lujing uranium ore-field, central-southern China. The results of static analysis on these reserves show that the residual geological reserves of both Lujing and Huangfengling deposit belong to sub-profitable type, but the ones of Yangjiaonao deposit is profitable with 26.56% tax-before profit. 1 tU profitable type of ore from Yangjiaonao deposit can use 2.40-3.79 tU subprofitable type of ores from Lujing and Huangfengling deposit. In order to solving the problem on scarcity of backup resources of the depleted mines in Lujing uranium ore-field and using the existing sub-profitable type of geological reserves, it is suggested that the high grade of profitable type of deposits should be explored around the exhausting mines so that the production of the mines could be profitable by the pithead heap-leaching mining method with arrangement groups of both sub-profitable and profitable type of ores.

    The United States Exclusive Economic Zone (EEZ) was established in 1983 and comprises all marine areas within 200 nautical miles (370 kilometers) of the nearest U.S. land. This vast area of 3.38 million square nautical miles (11.6 million square kilometers) is about 20 percent greater than the entire land area of the United States. The resource potential of the vast mineral deposits that occur within the U.S. EEZ is unknown, despite field studies that have taken place during the past 25 years. Since about 1975, information on marine mineral deposits has been obtained by numerous research cruises to the Pacific Ocean by the U.S. Geological Survey (USGS), the U.S. National Oceanic and Atmospheric Administration (NOAA), equivalent government agencies in Germany, Canada, France, Russia, Japan, China, South Korea, Australia, and New Zealand, and by academic researchers from all of these nations. Although most of the cruises by other nations explored areas outside the U.S. EEZ, information gained from those studies can aid in the evaluation of the mineral potential in the U.S. EEZ. However, the global effort remains inadequate to allow for the quantitative evaluation of mineral resources contained within the EEZ of nations or within international regions of the oceans.

    Implementation of efforts to screen older people for fall risk-and to intervene before falls occur-have been scattershot at best. Ongoing studies of fall prevention called STRIDE (Strategies to Reduce Injuries and Develop Confidence in Elders) might change that. The studies look at whether clinicians can implement a fall-prevention program across rural, urban, and suburban treatment settings.

    Energy resources, the basic input in every area of the economy, have a fundamental function for society's welfare. Traditional energy resources are, however, rapidly decreasing. Energy supply has been falling behind in meeting global demand, and is causing increased focus on efficiency and economy concepts in recent energy policies. Since the existing energy resources are not spread evenly among the countries, but instead are concentrated in certain regions and countries, a monopolistic situation arises. Equally, supply assurance is an issue, since the energy supply is held by certain regions and countries who have monopolistic pricing power. Both the EU and many other countries are studying how to marketize energy. This book focuses on the importance of energy and the problems posed by it. It will be useful for the academic community, related sectors and decision makers.

    Fear of falling may be as debilitating as the fall itself, leading to a restriction in activities and even a loss of autonomy. The main objective was to evaluate the prevalence of the fear of falling among elderly fallers. The secondary objectives were to determine the factors associated with the fear of falling and evaluate the impact of this fear on the activity "getting out of the house". Prospective study conducted between 1995 and 2006 in which fallers and patients at high risk for falling were seen at baseline by the multidisciplinary falls consultation team (including a geriatrician, a neurologist and a physical medicine and rehabilitation physician) and then, again 6 month later, by the same geriatrician. The fear of falling was evaluated with a yes/no question: "are you afraid of falling?". Out of 635 patients with a mean age of 80.6 years, 502 patients (78%) expressed a fear of falling. Patients with fear of falling were not older than those who did not report this fear, but the former were mostly women (Pfear of falling were not going out alone as much as the fearless group (31% vs 53%, Pfearful group admitted to avoiding going out because they were afraid of falling. The strong prevalence of the fear of falling observed in this population and its consequences in terms of restricted activities justifies systematically screening for it in fallers or patients at risk for falling.

    Falls are the leading cause of unintentional injury in women. During pregnancy, even a minor fall can result in adverse consequences. Evidence to inform effective and developmentally appropriate pregnancy fall prevention programs is lacking. Early research on pregnancy fall prevention suggests that exercise may reduce falls. However, acceptability and effectiveness of pregnancy fall prevention programs are untested. To better understand postpartum women's perspective and preferences on fall prevention strategies during pregnancy to formulate an intervention. Focus groups and individual interviews were conducted with 31 postpartum women using descriptive qualitative methodology. Discussion of falls during pregnancy and fall prevention strategies was guided by a focus group protocol and enhanced by 1- to 3-minute videos on proposed interventions. Focus groups were audio recorded, transcribed, and analyzed using NVivo 10 software. Emerging themes were environmental circumstances and physical changes of pregnancy leading to a fall, prevention strategies, barriers, safety concerns, and marketing a fall prevention program. Wet surfaces and inappropriate footwear commonly contributed to falls. Women preferred direct provider counseling and programs including yoga and Pilates. Fall prevention strategies tailored to pregnant women are needed. Perspectives of postpartum women support fall prevention through provider counseling and individual or supervised exercise programs.

    Falls are a major source of hospitalization, long-term institutionalization, and death in older adults and patients with Parkinson’s disease (PD). Limited attentional resources are a major risk factor for falls. In this review, we specify cognitive–behavioral mechanisms that produce falls and map these mechanisms onto a model of multi-system degeneration. Results from PET studies in PD fallers and findings from a recently developed animal model support the hypothesis that falls result from in...

  10. Predicting falls using two instruments (the Hendrich Fall Risk Model and the Morse Fall Scale) in an acute care setting in Lebanon.

    To assess the predictive value of two instruments (the Morse Fall Scale (MFS) and the Heindrich II Fall Risk Model (HFRM)] in a Middle Eastern country (Lebanon) and to evaluate the factors that are related to falls. A prospective observational cross-sectional design was used. Falls and fall-related injuries in the acute care settings contribute a substantial health and economic burden on patients and organisations. Preventing falls is a priority for most healthcare organisations. While the risk of falling cannot be eliminated, it can be significantly reduced through accurate assessment of patients' risk of falling. Data from 1815 inpatients at the American University of Beirut Medical Center (AUBMC) in Lebanon were evaluated using two instruments to predict falls: the MFS and the HFRM. The incidence of falls was 2·7% in one year. The results indicate that while the instruments were significantly correlated, the HFRM was more sensitive in predicting falls than the MFS. The internal consistency of both scales was moderate, but inter-rater reliability was high. Patients using antiepileptic drugs and assistance devises had higher odds of falling. Although both instruments were easy to use in a Middle Eastern country, the HFRM rather than the MFS is recommended for inpatients in an acute care setting as it had higher sensitivity and specificity. It is recommended that while the HFRM had adequate sensitivity, it is not seamless, and as such, nurses should not rely entirely on it. Rather, nurses should use their expert clinical judgement, their ethical obligations and cultural considerations to implement a safer environment of care for the patient. © 2013 John Wiley & Sons Ltd.

    In early 2009 an exciting opportunity was presented to the Geographic Information Systems (GIS) team at the Savannah River Site (SRS). The SRS maintenance group was directed to maintain all Out-falls on Site, increasing their workload from 75 to 183 out-falls with no additional resources. The existing out-fall inspection system consisted of inspections performed manually and documented via paper trail. The inspections were closed out upon completion of activities and placed in file cabinets with no central location for tracking/trending maintenance activities. A platform for meeting new improvements required for documentation by the Department of Health and Environmental Control (DHEC) out-fall permits was needed to replace this current system that had been in place since the 1980's. This was accomplished by building a geographically aware electronic application that improved reliability of site out-fall maintenance and ensured consistent standards were maintained for environmental excellence and worker efficiency. Inspections are now performed via tablet and uploaded to a central point. Work orders are completed and closed either in the field using tablets (mobile application) or in their offices (via web portal) using PCs. And finally completed work orders are now stored in a central database allowing trending of maintenance activities. (authors)

    Full Text Available Abstract Background Falls are among the most common adverse events reported in hospitalized patients. While there is a growing body of literature on fall prevention in the hospital, the data examining the fall rate and risk factors for falls in the immediate post-hospitalization period has not been well described. The objectives of the present study were to determine the fall rate of in-hospital fallers at home and to explore the risk factors for falls during the immediate post-hospitalization period. Methods We identified patients who sustained a fall on one of 16 medical/surgical nursing units during an inpatient admission to an urban community teaching hospital. After discharge, falls were ascertained using weekly telephone surveillance for 4 weeks post-discharge. Patients were followed until death, loss to follow up or end of study (four weeks. Time spent rehospitalized or institutionalized was censored in rate calculations. Results Of 95 hospitalized patients who fell during recruitment, 65 (68% met inclusion criteria and agreed to participate. These subjects contributed 1498 person-days to the study (mean duration of follow-up = 23 days. Seventy-five percent were African-American and 43% were women. Sixteen patients (25% had multiple falls during hospitalization and 23 patients (35% suffered a fall-related injury during hospitalization. Nineteen patients (29% experienced 38 falls at their homes, yielding a fall rate of 25.4/1,000 person-days (95% CI: 17.3-33.4. Twenty-three patients (35% were readmitted and 3(5% died. One patient experienced a hip fracture. In exploratory univariate analysis, persons who were likely to fall at home were those who sustained multiple falls in the hospital (p = 0.008. Conclusion Patients who fall during hospitalization, especially on more than one occasion, are at high risk for falling at home following hospital discharge. Interventions to reduce falls would be appropriate to test in this high-risk population.

    The North Slope of Alaska is experiencing rapid changes in response to interacting climate and socioeconomic drivers. The North Slope Science Initiative (NSSI) is using scenarios as a tool to identify plausible, spatially explicit future states of resource extraction activities on the North Slope and adjacent seas through the year 2040. The objective of the scenarios process is to strategically assess research and monitoring needs on the North Slope. The participatory scenarios process involved stakeholder input (including Federal, State, local, academic, industry and non-profit representatives) to identify key drivers of change related to resource extraction activities on the North Slope. While climate change was identified as a key driver in the biophysical system, economic drivers related to oil and gas development were also important. Expert-reviewed informational materials were developed to help stakeholders obtain baseline knowledge and stimulate discussions about interactions between drivers, knowledge gaps and uncertainties. Map-based scenario products will allow mission-oriented agencies to jointly explore where to prioritize research investments and address risk in a complex, changing environment. Scenarios consider multidecadal timescales. However, tracking of indicator variables derived from scenarios can lead to important insights about the trajectory of the North Slope social-environmental system and inform management decisions to reduce risk on much shorter timescales. The inclusion of stakeholders helps provide a broad spectrum of expert viewpoints necessary for considering the range of plausible scenarios. A well-defined focal question, transparency in the participation process and continued outreach about the utility and limitations of scenarios are also important components of the scenarios process.

    The objective of this study was to define fall rates and to identify possible fall risk factors in adult patients with severe haemophilia. 147 patients with severe haemophilia A and B were evaluated using a standardized test battery consisting of demographic, medical and clinical variables and fall evaluation. 41 (27.9 %) patients reported a fall in the past 12 months, 22 (53.7 %) of them more than once. Young age, subjective gait insecurity and a higher number of artificial joints seem to be risk factors for falling. Falls seem to be a common phenomenon in patients with severe haemophilia. Fall risk screening and fall prevention should be implemented into daily practice.

    Full Text Available Objectives: To evaluate the repercussion of falls in the elderly peoplewho live in the city of São Paulo and address - though synthetically- some questions regarding the city and its relation to aging and thequality of life of the elderly. Methods: This is a qualitative study. As fordata collection, “in-depth individual interviews” were applied. Selectionof subjects was guided by a procedure named as “network”. Results:Ten interviews were performed, nine with elderly individuals who werevictims of falls and one with a public authority representative. Dataresulting from interviews confirmed that significant changes occurin live of the elderly, who are victims of what has been called “urbantraps”, and that, by extrapolating mobility and dependence contexts,invade feelings, emotions and desires. The inappropriate environmentprovided by the city of São Paulo is confirmed by absence of adequateurban planning and lack of commitment of public authorities. It alsorevealed that the particular way of being old and living an elderlylife, in addition to right to citizenship, is reflected by major or lesserdifficulties imposed to the elderly to fight for their rights and have theirpublic space respected. Conclusion: The city of São Paulo is not anideal locus for an older person to live in. To the traps that are found inpublic places one can add those that are found in private places andthat contribute to the hard experience of falls among the elderly, anexperience that is sometimes fatal. In Brazil, the attention is basicallyfocused on the consequences of falls and not on prevention, by meansof urban planning that should meet the needs of the most vulnerablegroups - the physically disabled and the elderly.

    We aimed to estimate the proportion of nursing assistants (NAs) in the US with work-related injuries and insufficient socio-economic resources by race/ethnicity. Data from the 2004 National Nursing Assistant Survey (NNAS), a nationally representative sample survey of NAs employed in United States nursing homes, were analyzed accounting for the complex survey design. Among 2,880 participants, 44% reported "scratch, open wounds, or cuts" followed by "back injuries" (17%), "black eyes or other types of bruising" (16%), and "human bites" (12%). When compared to non-Hispanic white NAs, the adjusted rate ratio (RR) for wound/cut was 0.74 for non-Hispanic black NAs (95% confidence interval [CI]: 0.65-0.85). RRs for black eyes/bruises were 0.18 for non-Hispanic black NAs (95% CI: 0.12-0.26), and 0.55 for Hispanic NAs (95% CI: 0.37-0.82). Minority racial and ethnic groups were less likely to report having experienced injuries compared with non-Hispanic white NAs. Future research should focus on identifying preventable risk factors, such as differences by race and ethnicity in the nature of NA jobs and the extent of their engagement in assisting patients with activities of daily living. © 2010 Wiley-Liss, Inc.

    Performance-Based Ratemaking (PBR) is a form of utility regulation that strengthens the financial incentives to lower rates, lower costs, or improve nonprice performance relative traditional regulation, which the authors call cost-of-service, rate-of-return (COS/ROR) regulation. Although the electric utility industry has considerable experience with incentive mechanisms that target specific areas of performance, implementation of mechanisms that cover a comprehensive set of utility costs or services is relatively rare. In recent years, interest in PBR has increased as a result of growing dissatisfaction with COS/ROR and as a result of economic and technological trends that are leading to more competition in certain segments of the electricity industry. In addition, incentive regulation has been used with some success in other public utility industries, most notably telecommunications in the US and telecommunications, energy, and water in the United Kingdom. In this report, the authors analyze comprehensive PBR mechanisms for electric utilities in four ways: (1) they describe different types of PBR mechanisms, (2) they review a sample of actual PBR plans, (3) they consider the interaction of PBR and utility-funded energy efficiency programs, and (4) they examine how PBR interacts with electric utility resource planning and industry restructuring. The report should be of interest to technical staff of utilities and regulatory commissions that are actively considering or designing PBR mechanisms. 16 figs., 17 tabs.

    Full Text Available Implementing an effective environmental policy is complicated by the absence of proper provision of reliable information on the environmental activities of participants of an economic activity. In such circumstances, there is an increase of the role of business transactions audit related to the formation of expenses for protection and rational use of natural resources in order to express an independent opinion on their reliability, appropriateness, legality, efficiency in all material aspects in accordance with the requirements of users. The lack of comprehensive methodology and tools for practical audit of costs and its results during the formation of environmental measures in the workplace remains as an unresolved issue. To solve this problem the author has investigated the methods of forming environmental costs of an enterprise in areas of environmental activities in terms of their consideration as the object of audit. The system of tasks for auditing transactions forming environmental costs is formulated. The objects of the audit of environmental costs are identified; their essence is revealed and the approach to the mechanism of their formation is considered. The narrow spaces are revealed, and the problematic issues while forming environmental costs in the accounting system of the company are systematized. The author proposes a set of analytical indicators which can be used in environmental audits of the company and its responsibilities related to environmental protection. The directions for further research on finding ways of harmonizing bookkeeping, statistical accounting and tax calculations of environmental costs are determined.

    Full Text Available Introduction: Greenhouse gases absorb the radiation reflected from the earth surface which would otherwise be sent back into space. The composition and mixture of these gases make life on earth possible. In recent years, human activity has affected both the composition and mixture of the atmosphere, modifying the climate. When climate changes, crop production is affected. There are many studies that consider the type and amount of production changes for particular crops, places and scenarios. Others attempt to expand knowledge about production changes and their impacts on economy and regional welfare. Climate change affects agriculture through direct and indirect affects i.e. temperature, and precipitation changes in the biological and physical environment. Restriction in water availability is one of the most dramatic consequences of climate change for the agricultural sector. Water availability is expected to be even more limited in the future. Scarcity of water is due to potential evapotranspiration increase. It is related to increase in air and earth surface temperatures. This phenomenon is important in low-precipitation seasons, and is even more severe in dry areas. The number of regions with loss of soil moisture is expected to increase, resulting in direct economic consequences on the production capacity. Considering the above decisions, the main objective of this paper is to integrate climate change into agricultural decision-making by using an Economic Modeling System to identify the impacts of climate change induced by greenhouse gas emissions on agricultural sector productions and available water resources in the down lands of the Taleghan Dam. Materials and Methods: In this study, the effects of greenhouse gases on climate variables of temperature and precipitation under emission scenarios A1B, A2 and B1 were evaluated using time series data from 1981- 2008 and General Circulation Models (GCM. Then Ordinary Least Squares (OLS was used

    This paper proposes on the design of a walker for the prevention of falling among elderlies or patients during rehabilitation whenever they use a walker to assist them. Fall happens due to impaired balance or gait problem. The assistive device is designed by applying stability concept and an accelerometric fall detection system is included. The accelerometric fall detection system acts as an alerting device that acquires body accelerometric data and detect fall. Recorded accelerometric data could be useful for further assessment. Structural strength of the walker was verified via iterations of simulation using finite element analysis, before being fabricated. Experiments were conducted to identify the fall patterns using accelerometric data. The design process and detection of fall pattern demonstrates the design of a walker that could support the user without fail and alerts the helper, thus salvaging the users from injuries due to fall and unattended situation.

    The objectives were to assess the associations between fall-related injuries (FRIs) treated in the emergency department (ED) among older adults in California and contextual county-level physical, social, and economic characteristics, and to assess how county-level economic conditions are associated with FRIs when controlling for other county-level factors. Data from 2008 California ED discharge, Medicare Impact File, and County Health Rankings were used. Random effects logistic regression models estimated contextual associations between county-level factors representing economic conditions, the built environment, community safety, access to care, and obesity with patient-level FRI treatment among 1,712,409 older adults, controlling for patient-level and hospital-level characteristics. Patient-level predictors of FRI treatment were consistent with previous studies not accounting for contextual associations. Larger and rural hospitals had higher odds of FRI treatment, while teaching and safety net hospitals had lower odds. Better county economic conditions were associated with greater odds (ß=0.73, P=0.001) and higher county-level obesity were associated with lower odds (ß=-0.37, P=0.004), but safer built environments (ß=-0.31, P=0.38) were not associated with FRI treatment. The magnitude of association between county-level economic conditions and FRI treatment attenuated with the inclusion of county-level obesity rates. FRI treatment was most strongly and consistently related to more favorable county economic conditions, suggesting differences in treatment or preferences for treatment for FRIs among older individuals in communities of varying resource levels. Using population health data on FRIs, policy makers may be able to remove barriers unique to local contexts when implementing falls prevention educational programs and built environment modifications.

    Full Text Available In the present study it is intended to characterize the history of falls and to evaluate the fear to fall in aged institutionalized. The sample is composed for 113 institutionalized aged people, 32 men and 81 women with a average 82,96 ± 7,03 age of years. The data had been collected by means of a questionnaire and statistical analyzed (descriptive statistics, parametric tests - Test T and Anova - Test U-Mann Whitney, and Test of Kruskal-Wallis – and the Test of Tukey. The results point in the direction of that the women present a bigger number of falls (24.8% and greater fear to fall (Med=55. The falls had occurred in its majority in the context of the room of the institutions. It was verified that people who had at least a fall experience present greater fear to fall comparatively (Med=55 with that they had not the same had no incident of fall in period of time (Med=77. Our results come to strengthen the hypothesis of the changeable sex to be able to be considered a factor of fall risk. Aged that they present a history of falls seems to be more vulnerable to develop the fear to fall.

  14. Mitigating fall risk: A community fall reduction program.

    Reinoso, Humberto; McCaffrey, Ruth G; Taylor, David W M

    One fourth of all American's over 65 years of age fall each year. Falls are a common and often devastating event that can pose a serious health risk for older adults. Healthcare providers are often unable to spend the time required to assist older adults with fall risk issues. Without a team approach to fall prevention the system remains focused on fragmented levels of health promotion and risk prevention. The specific aim of this project was to engage older adults from the community in a fall risk assessment program, using the Stopping Elderly Accidents, Deaths & Injuries (STEADI) program, and provide feedback on individual participants' risks that participants could share with their primary care physician. Older adults who attended the risk screening were taking medications that are known to increase falls. They mentioned that their health care providers do not screen for falls and appreciated a community based screening. Copyright © 2017 Elsevier Inc. All rights reserved.

    Adopting a unique Spanish perspective, this study aims to assess healthcare resource utilization (HCRU) and the costs of treating nosocomial pneumonia (NP) produced by methicillin-resistant Staphylococcus aureus (MRSA) in hospitalized adults using linezolid or vancomycin. An evaluation is also made of the renal failure rate and related economic outcomes between study groups. An economic post hoc evaluation of a randomized, double-blind, multicenter phase 4 study was carried out. Nosocomial pneumonia due to MRSA in hospitalized adults. The modified intent to treat (mITT) population comprised 224 linezolid- and 224 vancomycin-treated patients. Costs and HCRU were evaluated between patients administered either linezolid or vancomycin, and between patients who developed renal failure and those who did not. Analysis of HCRU outcomes and costs. Total costs were similar between the linezolid- (€17,782±€9,615) and vancomycin-treated patients (€17,423±€9,460) (P=.69). The renal failure rate was significantly lower in the linezolid-treated patients (4% vs. 15%; Prenal failure (€19,626±€10,840 vs. €17,388±€9,369; P=.14). Among the patients who developed renal failure, HCRU (days on mechanical ventilation: 13.2±10.7 vs. 7.6±3.6 days; P=.21; ICU stay: 14.4±10.5 vs. 9.9±6.6 days; P=.30; hospital stay: 19.5±9.5 vs. 16.1±11.0 days; P=.26) and cost (€17,219±€8,792 vs. €20,263±€11,350; P=.51) tended to be lower in the linezolid- vs. vancomycin-treated patients. There were no statistically significant differences in costs per patient-day between cohorts after correcting for mortality (€1000 vs. €1,010; P=.98). From a Spanish perspective, there were no statistically significant differences in total costs between the linezolid and vancomycin pneumonia cohorts. The drug cost corresponding to linezolid was partially offset by fewer renal failure adverse events. Copyright © 2016 Elsevier España, S.L.U. y SEMICYUC. All rights reserved.

  17. Falls and cerebellar ataxia

    Directory of Open Access Journals (Sweden)

    I. V. Damulin

    2015-01-01

    Full Text Available The paper considers the main causes of falls. Whatever their cause is, falls may lead to severe maladjustment in everyday life. In nearly 1 out of 10 cases, they are accompanied by severe injuries, including fractures (most commonly those of the proximal femur and humerus, hands, pelvic bones, and vertebrae, subdural hematoma, and severe soft tissue and head injuries. This process is emphasized to be multifactorial. Particular emphasis is laid on the involvement of the cerebellum and its associations, which may be accompanied by falls. This is clinically manifested mainly by gait disorders. Walking is a result of an interaction of three related functions (locomotion, maintenance of balance and adaptive reactions. In addition to synergies related to locomotion and balance maintenance, standing at rest and walking are influenced bythe following factors: postural and environmental information (proprioceptive, vestibular, and visual, the capacity to interpret and integrate this information, the ability of the musculoskeletal system to make movements, and the capability to optimally modulate these movements in view of the specific situation and the ability to choose and adapt synergy in terms of external factors and the capacities and purposes of an individual. The clinical signs of damage to the cerebellum and its associations are considered in detail. These structures are emphasized to be involved not only in movements, but also in cognitive functions. The major symptoms that permit cerebellar dysfunction to be diagnosed are given. Symptoms in cerebellar injuries are generally most pronounced when suddenly changing the direction of movements or attempting to start walking immediately after a dramatic rise. The magnitude of ataxia also increases in a patient who tries to decrease the step size. Falling tendencies or bending to one side (in other symptoms characteristic of cerebellar diseases suggest injury of the corresponding

  20. [Can falls be prevented?].

    Science.gov (United States)

    Dubousset, Jean

    2014-06-01

    Most recommendations and measures intended to prevent falls focus on the elderly (see HAS guideline of April 2009) but, in our opinion, this isfar too late: prevention must begin much earlier, not only by identifying persons at risk, but also by providing personalized lifestyle advice adapted to each individual's biomechanical, somatic, neurological and biological characteristics. The first preventive measure is to identify a possible deterioration of balance, starting with a physical examination at the age of 45 and repeated regularly throughout life. Extrinsic preventive measures focusing on the domestic and external environments are clearly necessary. But what is most important is to detect and, if necessary, correct any degradation of intrinsic (intracorporeal or somatic) factors starting at the age of 45 years; these include vision, vestibular function and balance, proprioception, and psychological and neurological status. Chronic illnesses and their treatments must also be taken into account: treatment must be limited to indispensable drugs; sedative psychotropics must be avoided if possible; and polymedication must be tightly controlled, as it is a major risk factor for falls. Prevention also requires a diet sufficiently rich in protein, calcium and vitamin D3 (to prevent osteoporosis), and regular daily exercise adapted to the individual, if possible associated with a simultaneous cognitive task. The last key point is the absolute need for thorough functional rehabilitation after any accidental or medical trauma, regardless of age, with the aim of restoring functional status to that existing prior to the accident.

    1979-07-01

    This study was made in order to determine if re-activating the retired High Falls Hydro Station in New York would result in a more economical generation of some of the power required in the Central Hudson System than is being obtained with the oil-burning thermal plants. The findings show that the construction of a new plant is more economical than rehabilitation of the existing station. All new construction schemes are marginally unattractive at today's costs but are found to become profitable within a short period as alternative energy sources escalate in price. A new powerhouse with an installed capacity of 2390 kW proved most economical, and its construction is recommended.

    Full Text Available Point-of-care CD4 tests at HIV diagnosis could improve linkage to care in resource-limited settings. Our objective is to evaluate the clinical and economic impact of point-of-care CD4 tests compared to laboratory-based tests in Mozambique.We use a validated model of HIV testing, linkage, and treatment (CEPAC-International to examine two strategies of immunological staging in Mozambique: (1 laboratory-based CD4 testing (LAB-CD4 and (2 point-of-care CD4 testing (POC-CD4. Model outcomes include 5-y survival, life expectancy, lifetime costs, and incremental cost-effectiveness ratios (ICERs. Input parameters include linkage to care (LAB-CD4, 34%; POC-CD4, 61%, probability of correctly detecting antiretroviral therapy (ART eligibility (sensitivity: LAB-CD4, 100%; POC-CD4, 90% or ART ineligibility (specificity: LAB-CD4, 100%; POC-CD4, 85%, and test cost (LAB-CD4, US$10; POC-CD4, US$24. In sensitivity analyses, we vary POC-CD4-specific parameters, as well as cohort and setting parameters to reflect a range of scenarios in sub-Saharan Africa. We consider ICERs less than three times the per capita gross domestic product in Mozambique (US$570 to be cost-effective, and ICERs less than one times the per capita gross domestic product in Mozambique to be very cost-effective. Projected 5-y survival in HIV-infected persons with LAB-CD4 is 60.9% (95% CI, 60.9%-61.0%, increasing to 65.0% (95% CI, 64.9%-65.1% with POC-CD4.

    2018-05-01

    One in three older adults falls each year. There are approximately 2.5 million falls among older adults treated in emergency departments. Falls account for 87% of all fractures in this age group. The biggest risk factor for falling is a history of falls. Other risk factors include frailty, sedative and anticholinergic drugs, polypharmacy, and a variety of medical conditions. Current recommendations are that all patients age 65 years and older should be asked about falls each year. Patients also can be screened for fall risk with a variety of approaches including questionnaires and the Timed Up & Go test. For patients who have fallen or are at risk, care should focus on correcting reversible home environmental factors that predispose to falls, minimizing the use of drugs with sedating properties, addressing vision conditions, recommending physical exercise (including balance, strength, and gait training), and managing postural hypotension as well as foot conditions and footwear. In addition, vitamin D and calcium supplementation should be considered. For patients needing anticoagulation for medical reasons, an assessment must balance fall risk (and thus bleeding from a fall) versus the risk of discontinuing anticoagulation (eg, sustaining an embolic stroke from atrial fibrillation).

    1989-09-01

    Klamath Falls, Oregon, is located in a Known Geothermal Resource Area which has been used by residents, principally to obtain geothermal fluids for space heating, at least since the turn of the century. Over 500 shallow-depth wells ranging from 90 to 2,000 ft (27 to 610 m) in depth are used to heat (35 MWt) over 600 structures. This utilization includes the heating of homes, apartments, schools, commercial buildings, hospital, county jail, YMCA, and swimming pools by individual wells and three district heating systems. Geothermal well temperatures range from 100 to 230{degree}F (38 to 110{degree}C) and the most common practice is to use downhole heat exchangers with city water as the circulating fluid. Larger facilities and district heating systems use lineshaft vertical turbine pumps and plate heat exchangers. Well water chemistry indicates approximately 800 ppM dissolved solids, with sodium sulfate having the highest concentration. Some scaling and corrosion does occur on the downhole heat exchangers (black iron pipe) and on heating systems where the geo-fluid is used directly. 73 refs., 49 figs., 6 tabs.

    The present study was aimed at characterizing the soil-water resource degradation in the rural areas of Gurgaon and Mewat districts, the two economically contrasting areas in policy zones-II and III of the National Capital Region (NCR), and assessing the impact of the study area's local conditions on the type and extent of resource degradation. This involved generation of detailed spatial information on the land use, cropping pattern, farming practices, soils and surface/ground waters of Gurgaon and Mewat districts through actual resource surveys, standard laboratory methods and GIS/remote sensing techniques. The study showed that in contrast to just 2.54% (in rabi season) to 4.87% (in kharif season) of agricultural lands in Gurgaon district, about 11.77% (in rabi season) to 24.23% (in kharif season) of agricultural lands in Mewat district were irrigated with saline to marginally saline canal water. Further, about 10.69% of agricultural lands in the Gurgaon district and 42.15% of agricultural lands in the Mewat district were drain water irrigated. A large part of this surface water irrigated area, particularly in Nuh (48.7%), Nagina (33.5%), and Punhana (24.1%) blocks of Mewat district, was either waterlogged (7.4% area with water depth) or at risk of being waterlogged (17.1% area with 2-3 m ground water depth). Local resource inventory showed prevalence of several illegal private channels in Mewat district. These private channels divert degraded canal waters into the nearby intersecting drains and thereby increase extent of surface irrigated agricultural lands in the Mewat district. Geo-spatial analysis showed that due to seepage of these degraded waters from unlined drains and canals, ground waters of about 39.6% of Mewat district were salt affected (EC(m)ean = 7.05 dS/m and SAR(m)ean = 7.71). Besides, sub-surface drinking waters of almost the entire Mewat district were contaminated with undesirable concentrations of chromium (Cr 2.0-3.23 ppm), manganese (Mn: 0

    We report a simple experiment that clearly demonstrates a common error in the explanation of the classic experiment where a small piece of paper is put over a book and the system is let fall. This classic demonstration is used in introductory physics courses to show that after eliminating the friction force with the air, the piece of paper falls with acceleration g. To test if the paper falls behind the book in a nearly free fall motion or if it is dragged by the book, we designed a version of this experiment that includes a ball and a piece of paper over a book that is forced to fall using elastic cords. We recorded a video of our experiment using a high-speed video camera at 300 frames per second that shows that the book and the paper fall faster than the ball, which falls well behind the book with an acceleration approximately equal to g. Our experiment shows that the piece of paper is dragged behind the book and therefore the paper and book demonstration should not be used to show that all objects fall with acceleration g independently of their mass.

    Hydro-economic models can measure the economic effects of different operating rules, environmental restrictions, ecosystems services, technical constraints and institutional constraints. Furthermore, water allocation can be improved by considering economical criteria's. Likewise, climate and land use change can be analyzed to provide resilience. We developed and applied a hydro-economic optimization model to determine the optimal water allocation of main users in the Lower-middle São Francisco River Basin in Northeast (NE) Brazil. The model uses demand curves for the irrigation projects, small farmers and human supply, rather than fixed requirements for water resources. This study analyzed various constraints and operating alternatives for the installed hydropower dams in economic terms. A seven-year period (2000-2006) with water scarcity in the past has been selected to analyze the water availability and the associated optimal economic water allocation. The used constraints are technical, socioeconomic and environmental. The economically impacts of scenarios like prioritizing human consumption, impacts of the implementation of the São Francisco river transposition, human supply without high distribution losses, environmental hydrographs, forced reservoir level control, forced reduced reservoir capacity, alteration of lower flow restriction were analyzed. The results in this period show that scarcity costs related ecosystem service and environmental constraints are significant, and have major impacts (increase of scarcity cost) for consumptive users like irrigation projects. In addition, institutional constraints such as prioritizing human supply, minimum release limits downstream of the reservoirs and the implementation of the transposition project impact the costs and benefits of the two main economic sectors (irrigation and power generation) in the region of the Lower-middle of the São Francisco river basin. Scarcity costs for irrigation users generally

It is reported that approximately 60% of residents of aged care facilities fall each year. This is a major cause of morbidity and mortality, and a significant burden for health care providers and the health system. Among community dwelling older adults, exercise appears to be an effective countermeasure, but data are limited and inconsistent among studies in residents of aged care communities. This trial has been designed to evaluate whether the SUNBEAM program (Strength and Balance Exercise in Aged Care reduces falls in residents of aged care facilities. Research question: Is the program more effective and cost-effective than usual care for the prevention of falls? Design: Single-blinded, two group, cluster randomized trial. Participants and setting: 300 residents, living in 20 aged care facilities. Intervention: Progressive resistance and balance training under the guidance of a physiotherapist for 6 months, then facility-guided maintenance training for 6 months. Control: Usual care. Measurements: Number of falls, number of fallers, quality of life, mobility, balance, fear of falling, cognitive well-being, resource use, and cost-effectiveness. Measurements will be taken at baseline, 6 months, and 12 months. Analysis: The number of falls will be analyzed using a Poisson mixed model. A logistic mixed model will be used to analyze the number of residents who fall during the study period. Intention-to-treat analysis will be used. Discussion: This study addresses a significant shortcoming in aged care research, and has potential to impact

    Our objective was to determine international estimates of the economic burden of falls in older people living in the community. Our systematic review emphasized the need for a consensus on methodology for cost of falls studies to enable more accurate comparisons and subgroup-specific estimates among different countries. The purpose of this study was to determine international estimates of the economic burden of falls in older people living in the community. This is a systematic review of peer-reviewed journal articles reporting estimates for the cost of falls in people aged > or =60 years living in the community. We searched for papers published between 1945 and December 2008 in MEDLINE, PUBMED, EMBASE, CINAHL, Cochrane Collaboration, and NHS EED databases that identified cost of falls in older adults. We extracted the cost of falls in the reported currency and converted them to US dollars at 2008 prices, cost items measured, perspective, time horizon, and sensitivity analysis. We assessed the quality of the studies using a selection of questions from Drummond's checklist. Seventeen studies met our inclusion criteria. Studies varied with respect to viewpoint of the analysis, definition of falls, identification of important and relevant cost items, and time horizon. Only two studies reported a sensitivity analysis and only four studies identified the viewpoint of their economic analysis. In the USA, non-fatal and fatal falls cost US $23.3 billion (2008 prices) annually and US $1.6 billion in the UK. The economic cost of falls is likely greater than policy makers appreciate. The mean cost of falls was dependent on the denominator used and ranged from US $3,476 per faller to US $10,749 per injurious fall and US $26,483 per fall requiring hospitalization. A consensus on methodology for cost of falls studies would enable more accurate comparisons and subgroup-specific estimates among different countries.

    The American Geriatrics Society and British Geriatrics Society recommend that all adults older than 65 years be screened annually for a history of falls or balance impairment. The U.S. Preventive Services Task Force and American Academy of Family Physicians recommend exercise or physical therapy and vitamin D supplementation to prevent falls in community-dwelling older adults who are at increased risk of falls. Although the U.S. Preventive Services Task Force and American Academy of Family Physicians do not recommend routine multifactorial intervention to prevent falls in all community-dwelling older adults, they state that it may be appropriate in individual cases. The Centers for Disease Control and Prevention developed an algorithm to aid in the implementation of the American Geriatrics Society/British Geriatrics Society guideline. The algorithm suggests assessment and multifactorial intervention for those who have had two or more falls or one fall-related injury. Multifactorial interventions should include exercise, particularly balance, strength, and gait training; vitamin D supplementation with or without calcium; management of medications, especially psychoactive medications; home environment modification; and management of postural hypotension, vision problems, foot problems, and footwear. These interventions effectively decrease falls in the community, hospital, and nursing home settings. Fall prevention is reimbursed as part of the Medicare Annual Wellness Visit.

    The Sizewell B enquiry is discussed in the context of the wider question of whether nuclear power is the answer to UK energy policy for the future. Economies, costs, forecasting of energy demands, energy efficiency and alternatives to the nuclear option, are examined. It is felt that one of the most worrying features of the current debate is that for the Government and the electricity supply industry as much as for the objectors, quantifiable economic factors appear to be of less importance than emotional commitment to a nuclear policy.
