    Full Text Available The subject matter of the article is the description of economic growth. Modern economy is characterized by a high rate of changes. These changes are the limiting parameters of modern development, which requires a modification of the basic models of growth, the substantiation of the expediency and necessity of a rapid development strategy. In a simple mathematical form, the statement of the problem of economic growth in the “green economy” is examined, in which the costs of environmental measures are not considered a priori as hampering economic development (as it is common for a number of modern neoclassical and neo-Keynesian growth models. The methodological basis of the article are the econometric approach and modelling method. The article has a theoretical character. The main hypothesis supposes that the rapid development strategy cannot make an adequate development strategy under certain conditions, but may be acceptable in other its specific conditions. In this sense, the important growth conditions are the availability of resources, the effectiveness of institutions and the current economic structure, the technological effectiveness of economy, as well as the conditions of technological development (“green economy” and the path of such development. In the article, on the theoretical level of analysis, the substantiation of the adequacy of the rapid development strategy for an economic system is given, whose goal is to achieve the standard of living of the countryleader. Based on the assumptions introduced, the period for which the rapid development strategy might be implemented and the economic lag of the country might be reduced from the country-leader is determined. The conditions that ensure the impact of innovations on the rate of economic development are summarized. The introduced range of dependencies and relations can be useful for the elaboration of the theory of innovation development and for the formation of a new

    "Discussion of the macroeconomic consequences of rapid population growth is organized into three schools: pessimists, optimists, and the recent revisionists. For the revisionists, differing views are presented about the pervasiveness and relevance of market failures, such as the negative externalities of childbearing, and about the ability of families and institutions to adjust rapidly to changes brought on by rapid population growth. A welfare economics approach is used to review the merits of various public policies to reduce fertility, including public financing of family planning services and taxes and incentives associated with childbearing." The focus is on developing countries. excerpt

  3. Africa: rapid population increase retards development.

    1993-10-01

    The Organization of African Unity (OAU), the African Development Bank (ADB) and the UN Economic Commission for Africa (ECA) have criticized African governments for not taking the problem of unchecked population growth seriously enough. "Until recently most African governments did not view rapid population growth as a matter for concern," said the OAU assistant secretary-general for political affairs, Machivenyika Mapuranga, at a seminar on 'population and development'. The OAU estimates that an annual average population increase of 3.1% far outstrips Africa's economic growth, which in 1992 was less than 1%. Mapuranga acknowledged that cutting the population increase is an uphill struggle, especially among rural communities. African agriculture is largely labor intensive, sustained by smallholders, which encourages farmers to have more children. Like other wage earners, African farmers look to support from their family when they grow old and, for that reason, the number of children also counts. But with agricultural production growing at an average annual rate of 2.5%, self-sufficiency in food remains an elusive goal. Cities in sub-Saharan Africa are growing much faster than the overall rate of population increase of 3.1% per year. Between 1980 and 1988 the region's urban population increased at the rate of 6.9% a year. Urban areas now account for nearly 30% of the sub-Saharan Africa population, currently put at 680 million. By 2025, approximately 700 million people are expected to live in urban areas. Despite migration to towns, the rural population is expected to rise more than 68%, reaching over 590 million. full text

    The U.S. Geological Survey's (USGS) Prompt Assessment of Global Earthquakes for Response (PAGER) system, operational since mid 2007, rapidly estimates the most affected locations and the population exposure at different levels of shaking intensities. The PAGER system has significantly improved the way aid agencies determine the scale of response needed in the aftermath of an earthquake. For example, the PAGER exposure estimates provided reasonably accurate assessments of the scale and spatial extent of the damage and losses following the 2008 Wenchuan earthquake (Mw 7.9) in China, the 2009 L'Aquila earthquake (Mw 6.3) in Italy, the 2010 Haiti earthquake (Mw 7.0), and the 2010 Chile earthquake (Mw 8.8). Nevertheless, some engineering and seismological expertise is often required to digest PAGER's exposure estimate and turn it into estimated fatalities and economic losses. This has been the focus of PAGER's most recent development. With the new loss-estimation component of the PAGER system it is now possible to produce rapid estimation of expected fatalities for global earthquakes (Jaiswal and others, 2009). While an estimate of earthquake fatalities is a fundamental indicator of potential human consequences in developing countries (for example, Iran, Pakistan, Haiti, Peru, and many others), economic consequences often drive the responses in much of the developed world (for example, New Zealand, the United States, and Chile), where the improved structural behavior of seismically resistant buildings significantly reduces earthquake casualties. Rapid availability of estimates of both fatalities and economic losses can be a valuable resource. The total time needed to determine the actual scope of an earthquake disaster and to respond effectively varies from country to country. It can take days or sometimes weeks before the damage and consequences of a disaster can be understood both socially and economically. The objective of the U.S. Geological Survey's PAGER system is

  5. Are Global Economic Losses from Natural Hazards Increasing?

    Global society has long been influenced by natural hazards, but it has been widely noted that the economic cost of natural hazards has been rising rapidly over recent decades. This upward trend highlights the increasing exposure of the global economy to natural hazards and the need for society to understand the driving factors to help improve the resilience of communities. However disaster risk is driven by a plethora of factors, including population, wealth, land-use, and demographics. Consider also the natural variability in the frequency and severity of events, climate change, and implementation of resilience policies, and it becomes clear that disaster-risk management is a challenging field. To investigate the apparent upward trend in reported annual economic losses from natural disasters, socioeconomic factors known to influence the magnitude of losses must first be accounted for. Adjustment for these factors, known as loss normalisation, aims to estimate the losses sustained if historical events were to impact present day society. We have undertaken a detailed assessment of global economic losses from natural disasters for the period 1995 through 2013. Although the studied time-period is relatively short, expanding the investigated period would not necessarily produce more reliable insights owing to the inherent difficulty in obtaining accurate economic loss estimates for earlier periods and the challenge of finding consistent and reliable sources of socioeconomic data for the normalisation process. The results of the study, presented at a global and regional level, appear to suggest that the main driver of perceived increase in economic losses over the last ~20 years was the development of nations' economies (i.e. increase in population and wealth/GDP) and not in the natural hazards themselves. As populations all over the world migrate into areas of higher natural hazards regions (e.g. coastal areas or floodplain zones) and global wealth continues to

    Zn deficiency may be widespread in Asian countries such as South Korea. However, dietary habits have changed in response to rapid economic growth and globalization. Zn nutrition in South Koreans has therefore been assessed during a period (1969-1998) of unprecedented economic growth. Cross-sectional food consumption data from the Korean National Nutrition Survey Reports (KNNSR) of South Korea at four separate time points (1969, 1978, 1988 and 1998) were used to calculate Zn, Ca and phytate intakes using various food composition tables, databases and literature values. Nutrient values in local foods were cited from their analysed values. Average Zn intake was 5.8, 4.8 and 5.3 mg/d for 1969, 1978 and 1988 respectively, increasing to 7.3 mg/d in 1998 (73 % of the Korean Dietary Reference Intake). The phytate:Zn molar ratio decreased from 21 to 8 during the study period. Dietary Zn depletion due to marked decreases in cereal consumption, particularly barley which has a low Zn bioavailability, was counterbalanced by marked increases in the consumption of meat and fish, which are also Zn-rich foods. Reduced phytate consumption coincident with increased Zn intake suggests that Zn bioavailability also improved, particularly by 1998. Although total Zn intake was not greatly affected over the initial period of economic growth in South Korea (1969-1988), Zn contributions from different food sources changed markedly and both Zn intake and potential bioavailability were improved by 1998. The study may have implications for Zn nutrition in other Asian countries currently experiencing rapid economic growth.

    Full Text Available Surface water quality deterioration is a serious problem in many rapidly urbanizing catchments in developing countries. There is currently a lack of studies that quantify water quality variation (deterioration or otherwise due to both socio-economic and infrastructure development in a catchment. This paper investigates the causes of water quality changes over the rapid urbanization period of 1985–2009 in the Shenzhen River catchment, China and examines the changes in relation to infrastructure development and socio-economic policies. The results indicate that the water quality deteriorated rapidly during the earlier urbanization stages before gradually improving over recent years, and that rapid increases in domestic discharge were the major causes of water quality deterioration. Although construction of additional wastewater infrastructure can significantly improve water quality, it was unable to dispose all of the wastewater in the catchment. However, it was found that socio-economic measures can significantly improve water quality by decreasing pollutant load per gross regional production (GRP or increasing labor productivity. Our findings suggest that sustainable development during urbanization is possible, provided that: (1 the wastewater infrastructure should be constructed timely and revitalized regularly in line with urbanization, and wastewater treatment facilities should be upgraded to improve their nitrogen and phosphorus removal efficiencies; (2 administrative regulation policies, economic incentives and financial policies should be implemented to encourage industries to prevent or reduce the pollution at the source; (3 the environmental awareness and education level of local population should be increased; (4 planners from various sectors should consult each other and adapt an integrated planning approach for socio-economic and wastewater infrastructure development.

    Full Text Available Aim and Objectives: Rapid Maxillary Expansion constitutes a routine clinical procedure in orthodontics, involving separation of mid-palatine suture which is usually done with help of the Hyrax screw. However, because of its high cost, the use has been limited, especially in institutions. So, the purpose of this study was to construct an economical device which can expand the maxillary arch in growing patients. Materials and Methods: Six patients having constricted maxilla and posterior skeletal crossbite were randomly selected from the Department of Orthodontics. A unique, easy and simple alternative device for expanding the maxillary arch called economic Rapid Maxillary Expander (eRME has been fabricated at about one-tenth the cost of the conventional Hyrax. Pre- and post-treatment effects were statistically tested by using paired t-test at 0.05 level of significance. Results and Conclusion: The study results showed an average expansion in canine, premolar and molar regions of 4.4 mm, 6.8 mm and 9.4 mm, respectively, having significant difference pre-and post-treatment. Thus, it shows that maxillary expansion is efficiently possible with the application of this newly constructed device named eRME. This appliance also acts as a fixed retainer to avoid relapse, hence negating the need for a separate retainer.

    Rising income inequality is a global trend. Increased income inequality has been associated with higher rates of crime, greater consumer debt, and poorer health outcomes. The mechanisms linking inequality to poor outcomes among individuals are poorly understood. This research tested a behavioral account linking inequality to individual decision making. In three experiments ( n = 811), we found that higher inequality in the outcomes of an economic game led participants to take greater risks to try to achieve higher outcomes. This effect of unequal distributions on risk taking was driven by upward social comparisons. Next, we estimated economic risk taking in daily life using large-scale data from internet searches. Risk taking was higher in states with greater income inequality, an effect driven by inequality at the upper end of the income distribution. Results suggest that inequality may promote poor outcomes, in part, by increasing risky behavior.

    Full Text Available Understanding human mobility patterns provides knowledge about impacts of a socio-economic transformation in a rapidly urbanizing environment. This study assesses a long-term mobility data which uses a face-to-face questionnaire and GPS logger-based method of data collection for extracting socio-economic impacts from the rapid transformation. Conversion of mobility related information such as travel distance, direction, and time from the questionnaire survey into spatiotemporal information was carried out by developing an algorithm. To illustrate the proposed approach, a case study in Dawei Special Economic Zone, Myanmar was conducted. The results show that the questionnaire-based mobility data can be associated with GPS-based mobility data and diverse mobility patterns are found for different social groups in the stage of urban formation. The results enabled an understanding of the human dynamics in interactions, which can be used for monitoring rural sustainability and its challenges in the future with the background of the accelerated project development in the area.

    Magnesium (Mg) and Mg-alloys are being considered as implantable biometals. Despite their excellent biocompatibility and good mechanical properties, their rapid corrosion is a major impediment precluding their widespread acceptance as implantable biomaterials. Here, we investigate the potential for rapid solidification to increase the corrosion resistance of Mg alloys. To this end, the effect of rapid solidification on the environmental and stress corrosion behavior of the AZ80 Mg alloy vs. its conventionally cast counterpart was evaluated in simulated physiological electrolytes. The microstructural characteristics were examined by optical microscopy, SEM, TEM, and X-ray diffraction analysis. The corrosion behavior was evaluated by immersion, salt spraying, and potentiodynamic polarization. Stress corrosion resistance was assessed by Slow Strain Rate Testing. The results indicate that the corrosion resistance of rapidly solidified ribbons is significantly improved relative to the conventional cast alloy due to the increased Al content dissolved in the α-Mg matrix and the correspondingly reduced presence of the β-phase (Mg17 Al12 ). Unfortunately, extrusion consolidated solidified ribbons exhibited a substantial reduction in the environmental performance and stress corrosion resistance. This was mainly attributed to the detrimental effect of the extrusion process, which enriched the iron impurities and increased the internal stresses by imposing a higher dislocation density. In terms of immersion tests, the average corrosion rate of the rapidly solidified ribbons was <0.4 mm/year compared with ∼2 mm/year for the conventionally cast alloy and 26 mm/year for the rapidly solidified extruded ribbons. © 2014 Wiley Periodicals, Inc.

    Background Acute kidney injury (AKI) is common after severe paraquat poisoning and usually heralds a fatal outcome. The rapid large increases in serum creatinine (Cr) exceed that which can be explained by creatinine kinetics based on loss of glomerular filtration rate (GFR). Methods and Findings This prospective multi-centre study compared the kinetics of two surrogate markers of GFR, serum creatinine and serum cystatin C (CysC), following paraquat poisoning to understand and assess renal functional loss after paraquat poisoning. Sixty-six acute paraquat poisoning patients admitted to medical units of five hospitals were included. Relative changes in creatinine and CysC were monitored in serial blood and urine samples, and influences of non-renal factors were also studied. Results Forty-eight of 66 patients developed AKI (AKIN criteria), with 37 (56%) developing moderate to severe AKI (AKIN stage 2 or 3). The 37 patients showed rapid increases in creatinine of >100% within 24 hours, >200% within 48 hours and >300% by 72 hours and 17 of the 37 died. CysC concentration increased by 50% at 24 hours in the same 37 patients and then remained constant. The creatinine/CysC ratio increased 8 fold over 72 hours. There was a modest fall in urinary creatinine and serum/urine creatinine ratios and a moderate increase in urinary paraquat during first three days. Conclusion Loss of renal function contributes modestly to the large increases in creatinine following paraquat poisoning. The rapid rise in serum creatinine most probably represents increased production of creatine and creatinine to meet the energy demand following severe oxidative stress. Minor contributions include increased cyclisation of creatine to creatinine because of acidosis and competitive or non-competitive inhibition of creatinine secretion. Creatinine is not a good marker of renal functional loss after paraquat poisoning and renal injury should be evaluated using more specific biomarkers of renal injury

    Increasing regular physical activity is a key public health goal. One strategy is to change the physical environment to encourage walking and cycling, requiring partnerships with the transport and urban planning sectors. Economic evaluation is an important factor in the decision to fund any new transport scheme, but techniques for assessing the economic value of the health benefits of cycling and walking have tended to be less sophisticated than the approaches used for assessing other benefits. This study aimed to produce a practical tool for estimating the economic impact of reduced mortality due to increased cycling. The tool was intended to be transparent, easy to use, reliable, and based on conservative assumptions and default values, which can be used in the absence of local data. It addressed the question: For a given volume of cycling within a defined population, what is the economic value of the health benefits? The authors used published estimates of relative risk of all-cause mortality among regular cyclists and applied these to levels of cycling defined by the user to produce an estimate of the number of deaths potentially averted because of regular cycling. The tool then calculates the economic value of the deaths averted using the "value of a statistical life." The outputs of the tool support decision making on cycle infrastructure or policies, or can be used as part of an integrated economic appraisal. The tool's unique contribution is that it takes a public health approach to a transport problem, addresses it in epidemiologic terms, and places the results back into the transport context. Examples of its use include its adoption by the English and Swedish departments of transport as the recommended methodologic approach for estimating the health impact of walking and cycling.

    Full Text Available The changes in the Polish socio-economic system, initiated at the turn of 1989 and 1990, led to a systematic increase in the liberalization of economy and thereby the rise of the level of economic freedom. The aim of this paper is to examine the impact of the economic transition on the development of economic freedom in Poland. The analysis, carried out in the period 1995-2015, was conducted on the basis of the chain-linked Economic Freedom Index by the Fraser Institute and the Index of Economic Freedom of the Heritage Foundation and the Wall Street Journal. The analysis indicates that: (1 Poland cannot be considered as a country that is fully free economically, but the transition of its economic system has resulted in a rapid growth of economic freedom. (2 The impact of transition varies for different areas (sub-indices of the economy. (3 The European economic integration stimulated the increase of EFI, but the economic crisis did not decrease the level of economic freedom.

    The rapidly increasing range and expense of new diagnostics, compels consideration of a different, more proactive approach to health economic evaluation of diagnostic technologies. Early cycle economic evaluation is a decision analytic approach to evaluate technologies in development so as to increase the return on investment as well as patient and societal impact. This paper describes examples of 'early cycle economic evaluations' as applied to diagnostic technologies and highlights challenges in its real-time application. It shows that especially in the field of diagnostics, with rapid technological developments and a changing regulatory climate, early cycle economic evaluation can have a guiding role to improve the efficiency of the diagnostics innovation process. In the next five years the attention will move beyond the methodological and analytic challenges of early cycle economic evaluation towards the challenge of effectively applying it to improve diagnostic research and development and patient value. Future work in this area should therefore be 'strong on principles and soft on metrics', that is, the metrics that resonate most clearly with the various decision makers in this field.

  4. Long-Term Urban Market Dynamics Reveal Increased Bushmeat Carcass Volume despite Economic Growth and Proactive Environmental Legislation on Bioko Island, Equatorial Guinea

    Bushmeat hunting is extensive in west and central Africa as both a means for subsistence and for commercial gain. Commercial hunting represents one of the primary threats to wildlife in the region, and confounding factors have made it challenging to examine how external factors influence the commercial bushmeat trade. Bioko Island, Equatorial Guinea is a small island with large tracts of intact forest that support sizeable populations of commercially valuable vertebrates, especially endemic primates. The island also has a low human population and has experienced dramatic economic growth and rapid development since the mid-1990’s. From October 1997 – September 2010, we monitored the largest bushmeat market on Bioko in Malabo, recording over 197,000 carcasses for sale. We used these data to analyze the dynamics of the market in relation to political events, environmental legislation, and rapid economic growth. Our findings suggest that bushmeat hunting and availability increased in parallel with the growth of Equatorial Guinea’s GDP and disposable income of its citizens. During this 13-year study, the predominant mode of capture shifted from trapping to shotguns. Consequently, carcass volume and rates of taxa typically captured with shotguns increased significantly, most notably including intensified hunting of Bioko's unique and endangered monkey fauna. Attempts to limit bushmeat sales, including a 2007 ban on primate hunting and trade, were only transiently effective. The hunting ban was not enforced, and was quickly followed by a marked increase in bushmeat hunting compared to hunting rates prior to the ban. Our results emphasize the negative impact that rapid development and unenforced legislation have had on Bioko’s wildlife, and demonstrate the need for strong governmental support if conservation strategies are to be successful at preventing extinctions of tropical wildlife.

    Cosmic rays interact with the Earth's atmosphere to produce 14 C, which can be absorbed by trees. Therefore, rapid increases of 14 C in tree rings can be used to probe previous cosmic-ray events. By this method, three 14 C rapidly increasing events have been found. Plausible causes of these events include large solar proton events, supernovae, or short gamma-ray bursts. However, due to the lack of measurements of 14 C by year, the occurrence frequency of such 14 C rapidly increasing events is poorly known. In addition, rapid increases may be hidden in the IntCal13 data with five-year resolution. Here we report the result of 14 C measurements using an ancient buried tree during the period between BC 3388 and 3358. We found a rapid increase of about 9‰ in the 14 C content from BC 3372 to BC 3371. We suggest that this event could originate from a large solar proton event.

    Due to its rapid economic development, China is facing a huge health, social, and economic burden resulting from injuries. The study's objective was to examine Safe Communities in China as a strategy for injury prevention and safety promotion programmes in the era of rapid economic growth. Literature searches in English and Chinese, which included grey literature, were performed on the Chinese Journal Full-text Search System and Medline, using the words "Safe Community", "injury", "economics", and "prevention". The results showed that the existing 35 recognized members of the International Safe Community Network have not placed due emphasis on suicide prevention, which is one of the leading problems in both rural and urban China. A few groups, such as children, the elderly, cyclists, and pedestrians, have received due emphasis, while other vulnerable groups, such as migrant workers, motorcyclists, students, players, and farmers have not received the necessary attention from the Safe Community perspective. As the evidence describes, Safe Communities in China can be a very effective strategy for injury prevention, but four aspects need to be strengthened in the future: (1) establish and strengthen the policy and regulations in terms of injury prevention at the national level; (2) create a system to involve professional organizations and personnel in projects; (3) consider the economic development status of different parts of China; and (4) intentional injury prevention should receive greater attention.

    The economic crisis in Thailand in July 1997 had major social implications for unemployment, under employment, household income contraction, changing expenditure patterns, and child abandonment. The crisis increased poverty incidence by 1 million, of whom 54% were the ultra-poor. This paper explores and explains the short-term health impact of the crisis, using existing data and some special surveys and interviews for 2 years during 1998-99. The health impacts of the crisis are mixed, some being negative and some being positive. Household health expenditure reduced by 24% in real terms; among the poorer households, institutional care was replaced by self-medication. The pre-crisis rising trend in expenditure on alcohol and tobacco consumption was reversed. Immunization spending and coverage were sustained at a very high level after the crisis, but reports of increases in diphtheria and pertussis indicate declining programme quality. An increase in malaria, despite budget increases, had many causes but was mainly due to reduced programme effectiveness. STD incidence continued the pre-crisis downward trend. Rates of HIV risky sexual behaviour were higher among conscripts than other male workers, but in both groups there was lower condom use with casual partners. HIV serosurveillance showed a continuation of the pre-crisis downward trend among commercial sex workers (CSW, both brothel and non-brothel based), pregnant women and donated blood; this trend was slightly reversed among male STD patients and more among intravenous drug users. Condom coverage among brothel based CSW continued to increase to 97.5%, despite a 72% budget cut in free condom distribution. Poverty and lack of insurance coverage are two major determinants of absence of or inadequate antenatal care, and low birthweight. The Low Income Scheme could not adequately cover the poor but the voluntary Health Card Scheme played a health safety net role for maternal and child health. Low birthweight and

    The need to reduce the time it takes to establish a microbiological diagnosis and the emergence of new molecular microbiology and proteomic technologies has fuelled the development of rapid and point-of-care techniques, as well as the so-called point-of-care laboratories. These laboratories are responsible for conducting both techniques partially to response to the outsourcing of the conventional hospital laboratories. Their introduction has not always been accompanied with economic studies that address their cost-effectiveness, cost-benefit and cost-utility, but rather tend to be limited to the unit price of the test. The latter, influenced by the purchase procedure, does not usually have a regulated reference value in the same way that medicines do. The cost-effectiveness studies that have recently been conducted on mass spectrometry in the diagnosis of bacteraemia and the use of antimicrobials have had the greatest clinical impact and may act as a model for future economic studies on rapid and point-of-care tests.

    Full Text Available Rapid, efficient, and economic method for the isolation and purification of islets has been pursued by numerous islet-related researchers. In this study, we compared the advantages and disadvantages of our developed patented method with those of commonly used conventional methods (Ficoll-400, 1077, and handpicking methods. Cell viability was assayed using Trypan blue, cell purity and yield were assayed using diphenylthiocarbazone, and islet function was assayed using acridine orange/ethidium bromide staining and enzyme-linked immunosorbent assay-glucose stimulation testing 4 days after cultivation. The results showed that our islet isolation and purification method required 12 ± 3 min, which was significantly shorter than the time required in Ficoll-400, 1077, and HPU groups (34 ± 3, 41 ± 4, and 30 ± 4 min, respectively; P 1000 islets. In summary, the MCT method is a rapid, efficient, and economic method for isolating and purifying murine islet cell clumps. This method overcomes some of the shortcomings of conventional methods, showing a relatively higher quality and yield of islets within a shorter duration at a lower cost. Therefore, the current method provides researchers with an alternative option for islet isolation and should be widely generalized.

    Spectrometers and cameras are used in ultrafast spectroscopy to achieve high resolution in both time and frequency domains. Frequency-resolved signals from the camera pixels cannot be processed by common lock-in amplifiers, which have only a limited number of input channels. Here we demonstrate a rapid and economical method that achieves the function of a lock-in amplifier using mechanical choppers and a programmable microcontroller. We demonstrate the method's effectiveness by performing a frequency-resolved pump-probe measurement on the dye Nile Blue in solution.

    Today, many in the national and international NGO community perceive globalization and economic liberalization as a threat claiming that it widens inequalities and increases overall poverty. While it is true that inequality is on the rise in a rapidly globalizing world the real culprit is not globalization itself but rather a lack of economic reforms and economic liberalization. This paper aims to show that many in the international NGO community confuse cause and effect. The root cause of po...

  14. Insight into the Physical and Dynamical Processes that Control Rapid Increases in Total Flash Rate

    Rapid increases in total lightning (also termed "lightning jumps") have been observed for many decades. Lightning jumps have been well correlated to severe and hazardous weather occurrence. The main focus of lightning jump work has been on the development of lightning algorithms to be used in real-time assessment of storm intensity. However, in these studies it is typically assumed that the updraft "increases" without direct measurements of the vertical motion, or specification of which updraft characteristic actually increases (e.g., average speed, maximum speed, or convective updraft volume). Therefore, an end-to-end physical and dynamical basis for coupling rapid increases in total flash rate to increases in updraft speed and volume must be understood in order to ultimately relate lightning occurrence to severe storm metrics. Herein, we use polarimetric, multi-Doppler, and lightning mapping array measurements to provide physical context as to why rapid increases in total lightning are closely tied to severe and hazardous weather.

    2013-08-01

    Full Text Available Capitalism is a social adaptive system that evolve, change and grow in response to the challenges of a rapidly changing economic environment. When capitalism is seriously threatened by a systemic crisis, a new version much better adapted to existing conditions appears. Critical analysis of the fundamental ideas underlying neoclassical economic theory shows that the capitalist system is fundamentally a dynamic and therefore static neoclassical models proved to be unsuitable for studying it. Contrary to neoclassical economic vision, the capitalist economy is not governed by immutable economic laws. Global systemic crisis of capitalism that began in 2007 has highlighted the need for a new economic paradigm on which to be built and to be performed a new version of capitalism, in line with the increasingly complex realities of a globalized and quick changing world.

    Yun-Cheol Kim

    Full Text Available BACKGROUND: Purity, yield, speed and cost are important considerations in plasmid purification, but it is difficult to achieve all of these at the same time. Currently, there are many protocols and kits for DNA purification, however none maximize all four considerations. METHODOLOGY/PRINCIPAL FINDINGS: We now describe a fast, efficient and economic in-house protocol for plasmid preparation using glass syringe filters. Plasmid yield and quality as determined by enzyme digestion and transfection efficiency were equivalent to the expensive commercial kits. Importantly, the time required for purification was much less than that required using a commercial kit. CONCLUSIONS/SIGNIFICANCE: This method provides DNA yield and quality similar to that obtained with commercial kits, but is more rapid and less costly.

    Full Text Available Historically, birth rates in Alberta have followed closely the trajectory of change experienced by the other Canadian provinces. Its total fertility rate fell during the low point of the 1930s; it increased during the post-War baby boom in the 1950s and sixties, and thereafter fell to sub-replacement levels beginning in the mid 1970s. In recent years, especially since the early 2000s, the birth rate in Alberta has unexpectedly increased, such that by 2007, it had reached 1.90 children per woman---not far from the 2.1 level needed for generational replacement in the long term. During this same period both national and provincial fertility rates fluctuated at levels below those of Alberta (except Saskatchewan and Manitoba, whose rates have been higher. In this study, I examine the historical pattern of fertility change in Alberta, noting similarities and differences with the other provinces. I then look at the association of selected macro level factors (marriage, unemployment, wages, female labour force participation with change in total and parity-specific birth rates between 1997 and 2007, a period of unprecedented economic growth in Alberta. The statistical results show that although marriage is not significantly correlated with change in fertility rates, male and female wages and female labour force participation all show associations consistent with a procyclical interpretation of fertility change --- that is, periods of economic growth are conducive to fertility increase whereas bad economic times lead to reduced fertility.

  4. Income Inequality Explains Why Economic Growth Does Not Always Translate to an Increase in Happiness.

    2015-10-01

    One of the most puzzling social science findings in the past half century is the Easterlin paradox: Economic growth within a country does not always translate into an increase in happiness. We provide evidence that this paradox can be partly explained by income inequality. In two different data sets covering 34 countries, economic growth was not associated with increases in happiness when it was accompanied by growing income inequality. Earlier instances of the Easterlin paradox (i.e., economic growth not being associated with increasing happiness) can thus be explained by the frequent concurrence of economic growth and growing income inequality. These findings suggest that a more even distribution of growth in national wealth may be a precondition for raising nationwide happiness. © The Author(s) 2015.

    With rapid evolution of multidetector-row CT (MDCT) technology and applications, several factors such ad technology upgrade and turf battles for sharing cost and profitability affect MDCT workflow and economics. MDCT workflow optimization can enhance productivity and reduce unit costs as well as increase profitability, in spite of decrease in reimbursement rates. Strategies for workflow management include standardization, automation, and constant assessment of various steps involved in MDCT operations. In this review article, we describe issues related to MDCT economics and workflow. (orig.)

    Tobacco use is a leading cause of preventable death in the U.S. and around the world. Increasing tobacco price through higher taxes is an effective intervention both to reduce tobacco use in the population and generate government revenues. The goal of this paper is to review evidence on the economic impact of tobacco price increases through taxation with a focus on the likely healthcare cost savings and improvements in employee productivity. The search covered studies published in English from January 2000 to July 2012 and included evaluations of national, state, and local policies to increase the price of any type of tobacco product by raising taxes in high-income countries. Economic review methods developed for The Guide to Community Preventive Services were used to screen and abstract included studies. Economic impact estimates were standardized to summarize the available evidence. Analyses were conducted in 2012. The review included eight modeling studies, with seven providing estimates of the impact on healthcare costs and three providing estimates of the value of productivity gains. Only one study provided an estimate of intervention costs. The economic merit of tobacco product price increases through taxation was determined from the overall body of evidence on per capita annual cost savings from a conservative 20% price increase. The evidence indicates that interventions that raise the unit price of tobacco products through taxes generate substantial healthcare cost savings and can generate additional gains from improved productivity in the workplace.

    Conclusion: Road crash fatalities increased in recent decades in both Zambia and Botswana. But the rapid economic development in Botswana over this time period appears to have driven proportionate road traffic fatality increases. There are opportunities for newly emerging economies such as Zambia, Angola, and others to learn from the Botswana experience. Evidence-based investments in road safety interventions should be concomitant with economic development.

    Full Text Available A methodology of evaluating the economics of the front-end nuclear fuel cycle with a price change sensitivity analysis for a VVER-1000 reactor core as a case study is presented. The effect of increasing the fuel enrichment and its corresponding reactor cycle length on the energy cost is investigated. The enrichment component was found to represent the highly expenses dynamic component affecting the economics of the front-end fuel cycle. Nevertheless, the increase of the fuel enrichment will increase the reactor cycle length, which will have a positive feedback on the electricity generation cost (cent/KWh. A long reactor operation time with a cheaper energy cost set the nuclear energy as a competitive alternative when compared with other energy sources.

The main objective is to identify the competence areas required from fresh graduates for sustaining the contention of business enterprises and to analyse investments made by companies for developing talents within the framework of pressure generated by the economic crisis. The study take into consideration the partnership between the economic environment and higher education institutions as well as an anticipation of occupation trends for young graduates based on employee forecasts. Research results demonstrate the fact that the education system relies mainly on a transfer of knowledge and not on developing the competencies necessary for enhancing the employment chances of graduates or on their job performance. Only two out of ten employers are satisfied by the competencies demonstrated by graduates, the statistics being similar to the number of employers who collaborate with higher education institutions for providing adequate study programmes. From amongst the companies declaring that they provide continual development programmes, most invest in courses related to communication, team work and client orientation, although they are not satisfied with the graduates’ abilities in solving problems, making decisions or in leadership. A weak collaboration between companies and educational institutions generates a lack of rapid response from the educational system to the requirements of the market economy, amplifying the deficiency of competences, especially in fields with continual technological development or in those where new occupations are constantly appearing.

    Under the background of rapid agricultural economic development,rural financial and accounting work is of great significance. From rural accounting management system,rural accountant allocation and rural accounting training,this paper analyzes current situations of rural accounting work in China. In rural financial and accounting work,there are following problems. ( 1) Accounting behavior is not standard,and basic accounting work is to be further strengthened; ( 2) Internal control is not perfect and implementation of supervision mechanism is formalized; ( 3) Few people manipulate accounting behavior and accounting information is not transparent. In view of these problems,it puts forward countermeasures for improving rural accounting work: ( 1) establishing perfect agricultural accounting system; ( 2) regulating fund management order; ( 3) promoting computerized agricultural financial and accounting work; ( 4) improving professional and comprehensive quality of rural accountants.

    The interdependence between energy consumption and economic development are highlighted in this research, which focuses on energy price rises between 1973 and 1989. Three groups of countries are identified, developing and developed market economies and centrally planned economies. Two areas of interdependence are examined, firstly the dynamic relationship between primary energy consumption growth and real economic growth and secondly the static relationship between primary energy consumption and national income. In the period under review, developing market economies reacted most strongly to higher energy prices, with lower energy consumption while maintaining real growth in the Gross Domestic Product. However developing countries and centrally planned economies increased their energy consumption per unit of national income although the rate of increase slowed after 1975. (UK)

  16. An analysis of social consequences of rapid fertility decline in China.

    Science.gov (United States)

    Liu, Z; Liu, L

    1988-12-01

    Rapid fertility decline in China has brought about 2 direct effects: 1) the natural increase of the population has slowed down, and 2) the age structure has changed from the young to the adult type. These 2 effects have caused a series of economic and social consequences. Rapid fertility decline increases the gross national product per capita and accelerates the improvement of people's lives. Rapid fertility decline slows population growth and speeds up the accumulation of capital and the development of the economy. Since 1981, accumulation growth has exceeded consumption growth. Fertility decline alleviates the enrollment pressure on primary and secondary schools, raises the efficiency of education funds, and promotes the popularization of education. The family planning program strengthens the maternal and child health care and the medical care systems. As the result of economic development, the people's nutritional levels are improving. The physical quality of teenagers has improved steadily. The change in the age structure will alleviate the tension of rapid population growth and benefit population control in the next century. Fertility decline forces the traditional attitude toward childbearing from "more children, more happiness" to improved quality of children. The rapid fertility decline has caused a great deal of concern both inside and outside China about the aging of the population. The labor force, however, will continue to grow for the next 60 years. At present, China's population problems are still those of population growth.

    Full Text Available This paper investigates the relationship between economic expansion and the degree of formalization for the Brazilian labour market in the recent period. We present a theoretical framework that attempts to explain this relationship through the dynamics of firms hiring strategies. The main predictions are: the share of formal employment rises as the unemployment rate falls, and that the formal-informal wage gap increases, at least at the beginning of the economic expansion. In the empirical part, we use longitudinal microdata from a Brazilian household survey to check whether these two predictions are confirmed. To a large extent our results corroborate both predictions.

    1980-05-01

    Accusations that the Organization of Petroleum Exporting Countries (OPEC) created the world energy crisis and destroyed the economies of oil-importing nations are challenged by Dr. Merklein. He shows that the economic impact of OPEC price increases have only accelerated an already-developing energy shortage and only reflect the existing problems of inflation, unemployment, and declining currency exchange rates. The real problem is argued to be a US energy policy that is incapable of responding appropriately to what should be a manageable crude oil tax. When the arguments against OPEC policies are examined in an historical context, they are shown to be essentially neutral. 4 tables. (DCK)

    Science.gov (United States)

    Gu, J

    1983-07-29

    South Asia, which includes Central South Asia, Southeast Asia, and Southwest Asia, had a comparatively higher population growth rate during the 30-year postwar period because of the overall backward economy and strong religious tradition. From the viewpoint of economics, the high population growth in South Asia has slowed down economic growth, increased the foreign trade imblance, and worsened poverty. Secondly, the rapid population growth has overburdened the area's educational system. The illiteracy rate has been going up continuously because of inadequate funds available for education. Thirdly, young labor is lacking in skills, training, and work experience, and related productivity has declined. Consequently, profits, the investment capability, and wages are also declining. The problems of the oversupply of labor, unemployment, and poverty have also become increasingly serious. In addition, the rapid population growth has intensified the pressure on the food supply and worsened the average nutrition of the general public. In recent years, countries in South Asia have been trying to deal with various problems caused by the rapid population growth. Measures have been taken to control the population growth, with a redistribution of the population to places outside cities, and export labor to oil-producing nations of the Middle East and Africa in order to solve the problem of the domestic labor surplus and earn more income for the foreign exchange. Countries in South Asia need more time and effort to achieve a balance between the population growth and economic development.

    We investigated temporal trends in BMI, and assessed hypothesized predictors of trends including socio-economic position (SEP) and province-level economic development, in Argentina. Using multivariable linear regression, we evaluated cross-sectional patterning and temporal trends in BMI and examined heterogeneity in these associations by SEP and province-level economic development with nationally representative samples from Argentina in 2005 and 2009. We calculated mean annual changes in BMI for men and women to assess secular trends. Women, but not men, exhibited a strong cross-sectional inverse association between SEP and BMI, with the lowest-SEP women having an average BMI 2.55 kg/m(2) greater than the highest-SEP women. Analysis of trends revealed a mean annual increase in BMI of 0.19 kg/m(2) and 0.15 kg/m(2) for women and men, respectively, with slightly greater increases occurring in provinces with greater economic growth. No significant heterogeneity in trends existed by individual SEP. BMI is increasing rapidly over time in Argentina irrespective of various sociodemographic characteristics. Higher BMI remains more common in women of lower SEP compared with those of higher SEP.

    To evaluate temporal changes in recorded alcohol consumption in Sri Lanka during and after the armed conflict 1998-2013. District level alcohol sales, and mid-year population data for the whole study period (1998-2013) were consistently available from the Department of Excise and the Department of Census and Statistics for 18 of 25 districts. These data were used to estimate the recorded per capita consumption for the areas that were not directly exposed to the armed conflict. An interrupted time series design was employed to estimate the impact of the end of the armed conflict on recorded adult per capita alcohol consumption of population lived in the 18 districts. Adult per capita recorded alcohol consumption among Sri Lankans living in the 18 districts was 1.59 l of pure alcohol in 1998. This increased up to 2.07 l in 2009 and 2.55 l in 2013. Prior to the end of the conflict in 2009 adult per capita recorded consumption increased by 0.051 l of pure alcohol per year (95% CI: 0.029-0.074, P increased markedly after the end of the conflict. Rapid socio-economic development, alcohol industry penetration and lack of alcohol control strategies during the post-conflict period may have driven this increase. Adult per capita recorded alcohol consumption among Sri Lankans living in 18 districts that were not directly exposed to the armed conflict increased markedly after the end of the conflict in 2009, with a dramatic acceleration in the trend of per capita beer consumption. © The Author 2017.

  5. Exogenous Testosterone Rapidly Increases Aggressive Behavior in Dominant and Impulsive Men.

    Although traditional wisdom suggests that baseline levels of testosterone (T) promote aggressive behavior, decades of research have produced findings that have been largely weak and inconsistent. However, more recent experimental work suggests that exogenous administration of T rapidly potentiates amygdala and hypothalamus responses to angry facial expressions. Notably, these brain regions are rich in androgen receptors and play a key role in modulating aggressive behavior in animal models. The present experiment extends this work by examining whether acutely increasing T potentiates aggressive behavior in men. In a double-blind, placebo-controlled, between-subject design, healthy adult men (n = 121) were administered either T or placebo, and subsequently engaged in a well-validated decision-making game that measures aggressive behavior in response to social provocation. In light of prior correlational research, we also assessed the extent to which T's effects on aggressive behavior would depend on variability in trait dominance and/or trait self-control. Exogenous T on its own did not modulate aggressive behavior. However, T's effects on aggression were strongly influenced by variation in trait dominance and trait self-control. Specifically, T caused an increase in aggressive behavior, but only among men scoring relatively high in trait dominance or low in trait self-control. These findings are the first to demonstrate that T can rapidly (within 60 minutes) potentiate aggressive behavior, but only among men with dominant or impulsive personality styles.

    Full Text Available The article reveals the essence and systematizes the advantages of financial and economic integration. In the agro-industrial complex, this kind of integration contributes to attracting investments and reducing risks for investors, increasing the competitiveness and economic growth of the region. The relevance of the study is due to insufficiently researched remains many aspects of the functioning of integrated business systems in relation to individual industries, in particular, to agroindustrial production. The aim of the article is to study theoretical approaches to the essence of financial and economic integration in agro-industrial production and analyze the mechanism of investment support for the Russian agrarian sector, taking into account financial and economic integration. In preparing the article, general scientific methods of research were used: analysis and synthesis, generalization, comparison, classification. Results. The interpretation of financial and economic integration in Russian and foreign scientific publications is generalized. Distinctions of financial and economic integration are distinguished from other economic processes. The advantages of financial and economic integration for the economy and business entities are systematized. The importance of integrating industries and business entities in the agro-industrial complex, which is of strategic importance for ensuring Russia's food security, was noted. The branch structure of the agro-industrial complex is analyzed. The scheme of the integrated financial and economic mechanism in the agroindustrial complex is described. The importance of an optimal balance between cooperation and integration was underscored. The insufficiency of the methodological level of studies of agro-industrial integration is grounded. The components of the effect of financial and economic integration are considered. Positive effects of integration processes in the agroindustrial complex are

    The goal of this longitudinal study was to assess the impact of economic change and increased market integration on subsistence strategies, living conditions, growth, and nutritional status of Ribeirinhos living in the rural Amazon, Brazil. Data on weight, height, skinfolds, and circumferences, as well as data on economic strategies and living conditions were collected from 469 individuals in 2002 and 429 in 2009. Of these, 204 individuals were measured on both occasions. Independent and paired t-tests were used to identify changes in nutritional status over time in the larger sample and smaller, longitudinal subsample, respectively. Multiple linear regressions were used to examine the relationship between changes in economic/living conditions and nutritional status in the longitudinal subsample. Results indicate modest improvements in linear growth (HAZ) and among male children the observed increase was related to enrollment in the Brazilian conditional cash transfer program, Bolsa Família (P = 0.03). In terms of short-term measures of nutritional status, we found a significant increase in ZTSF and a reduction in ZUMA in most age/sex groups. Among subadults, there was a negative relationship between ZUMA and access to electricity (P = 0.01) and positive relationship between ZUMA and the sale of the açaí fruit (P = 0.04). Significant changes in weight and BMI (P economic strategies and lifestyle, changes in nutritional status were modest which may be explained by increased food insecurity documented during this early stage of transition. 2010 Wiley-Liss, Inc.

    2009-01-01

    China aims at quadrupling per-capita GDP by 2020 compared to the year 2000. Without any energy and environmental policy measures, this tremendous economic growth would be associated with a quadrupling of primary energy consumption up to 6.3 billion tons of standard coal equivalents (sce) and energy-related CO 2 -emissions of 13.9 billion tons Against this background, this paper is to set China's need to implement its sustainable development strategy into the quantitative context of the countries economic development and subsequent economic growth-related environmental problems. China is urgently searching for a way to ease the negative implications of economic growth and has committed itself to achieve a level of 3.0 billion ton sce primary energy consumption in 2020. As a consequence, the macro-economic energy intensity has to be reduced by 53% by 2020. A reduction of 53% by 2020 would lead to an energy intensity level 30% points below the year-2000 level of developed countries. As for natural resources, the expected economic growth will lead to an increase of crude oil net-imports up to 455 million ton sce in 2020 and 650 million ton sce in 2030. As for regional income distribution, economic growth helped to decrease existing inequities

  9. Strong economic growth driving increased electricity consumption

    The Finnish economy is growing faster today than anyone dared hope only a few years ago. Growth estimates for 2000 have already had to be raised. This strong level of economic growth has been reflected in electricity consumption, which has continued to increase, despite the exceptionally warm winter. A major part of this increased electricity usage has so far been met through imports. The continued growth in electricity imports has largely been a result of the fact that the good water level situation in Sweden and Norway, together with the mild winter, has kept electricity prices exceptionally low on the Nordic electricity exchange. The short period of low temperatures seen at the end of January showed, however, that this type of temperature fluctuation, combined with the restrictions that exist in regard to transfer capacity, can serve to push Nordic exchange electricity prices to record levels. This increase in price also highlights the fact that we are approaching a situation in which capacity will be insufficient to meet demand. A truly tough winter has not been seen since the Nordic region's electricity markets were deregulated. The lesson that needs to be learnt is that Finland needs sufficient capacity of her own to meet demand even during particularly cold winters. Finland used 77.9 billion kWh of electricity last year, up 1.6% or 1.3 billion kWh on 1998. This growth was relatively evenly distributed among different user groups. This year, electricity consumption is forecast to grow by 2-3%

    To understand the effect of economic growth on health, we investigated the trend in socio-economic and regional determinants of child health in Mongolia. This Central Asian country had the fastest economic growth amongst low and middle-income countries (LMICs) from 2000 to 2010 and a healthcare system in transition. Data was from Mongolian multiple indicator cluster surveys (MICS) in 2000, 2005 and 2010.

    Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID:27698865

  14. A CONCEPTUAL APPROACH TO ECONOMIC AGGLOMERATIONS

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Technological progress and rapid structural adjustments have characterized a lot of economies in the last century and they still feature pronounced structures. An important observation is that economic activities tend to agglomerate in space as a result of some kind increasing returns, forming eventually economic agglomerations. When various companies gather together, they establish specific forms of interaction. Increasing returns produce when this mutual interplay creates positive externalities for those firms which operate into an agglomeration. In this context, it is crucial to raise a question: what is an economic agglomeration and what do different scientists imply when using the concept? The phenomenon of agglomeration has attracted researchers from various disciplines employing a hybrid set of analytical perspectives. This whole framework is still puzzled with contradictory conceptualizations which are often used in an ambiguous way. Scientists tend to utilize notions such as agglomeration, cluster, territorial network, specialization, concentration somewhat interchangeably and with little concern about how to operationalize them. To shed a light on this issue, the aim of this paper is to provide a comprehensive analyze of different theoretical framework in which economic agglomerations have been debated and researched.

  16. Corticosterone rapidly increases thorns of CA3 neurons via synaptic/extranuclear glucocorticoid receptor in rat hippocampus

    Directory of Open Access Journals (Sweden)

    Miyuki eYoshiya

    2013-11-01

    Full Text Available Modulation of synapses under acute stress is attracting much attention. Exposure to acute stress induces corticosterone (CORT secretion from the adrenal cortex, resulting in rapid increase of CORT levels in plasma and the hippocampus. We tried to test whether rapid CORT effects involve activation of essential kinases as non-genomic processes.We demonstrated rapid effects (~ 1 h of CORT on the density of thorns, by imaging Lucifer Yellow-injected neurons in adult male rat hippocampal slices. Thorns of thorny excrescences of CA3 hippocampal neurons are post-synaptic regions whose presynaptic partners are mossy fiber terminals. The application of CORT at 100, 500 and 1000 nM induced a rapid increase in the density of thorns in the stratum lucidum of CA3 pyramidal neurons. Co-administration of RU486, an antagonist of glucocorticoid receptor (GR, abolished the effect of CORT. Blocking a single kinase, including MAPK, PKA or PKC, suppressed CORT-induced enhancement of thorn-genesis. On the other hand, GSK-3β was not involved in the signaling of thorn-genesis. Blocking AMPA receptors suppressed the CORT effect. Expression of CA3 synaptic/extranuclear GR was demonstrated by immunogold electron microscopic analysis. From these results, stress levels of CORT (100-1000 nM might drive the rapid thorn-genesis via synaptic/extranuclear GR and multiple kinase pathways, although a role of nuclear GRs cannot be completely excluded.

  17. Ecological economics and economic growth.

    Science.gov (United States)

    Victor, Peter A

    2010-01-01

    Boulding's 1966 paper on the economics of spaceship Earth established the framework for ecological economics and an understanding of economic growth. In ecological economics, economies are conceptualized as open subsystems of the closed biosphere and are subject to biophysical laws and constraints. Economic growth measured as an increase in real gross domestic product (GDP) has generally been associated with increases in the use of energy and materials and the generation of wastes. Scale, composition, and technology are the proximate determinants of environmental impacts. They are often reduced to two: scale (GDP) and intensity (impact per unit GDP). New work described in this paper defines "green" growth as intensity that declines faster than scale increases. Similarly, "brown" growth occurs when intensity declines more slowly than increases in scale, and "black" growth happens when both scale and intensity increase. These concepts are then related to the environmental Kuznets curve, which can be understood as a transition from brown to green growth. Ecological economics provides a macroperspective on economic growth. It offers broad policy principles, and it challenges the primacy of economic growth as a policy objective, but many important questions remain.

    Full Text Available The macroeconomic situation of a nation cannot be characterized just by the equilibrium conditions of its economy, but especially by the growth level and rate of the gross domestic product or the national, total income and per inhabitant. These are at the base to ensure the resources to raise the life standard of people, and for the overall progress of the country, for its honorable placement or framing in the national economy. The oscillations of the economic activities and the long term trend interweaved along centuries. Looked in a millenary retrospective by “L'Histoire” known magazine, they appear like: “while the brutal, short-term crises are well sighted, and the tri-decennial cycles have been defined by the Russian economist Kondratieff and are admitted, the long term movements are less known, those trends which make the succession of “The beautiful of the XIV century”, “The gloomy of the XVII century” and the XIX century, considered “grey”, the extraordinary of the XX century, the economics and economic historians are far from agreeing on the reality of these long movements, and if they admit them, they separate on their profound causes.”

    Little is published about the impact of the 2008 economic crisis on mental health services in Spain. An interrupted time series analysis was conducted to investigate a potential short-term association between the 2008 economic crisis and the number of psychiatric hospital admissions. The timing of the intervention (April 2008) was based on observed changes in Gross Domestic Product (GDP). Data on 1,152,880 psychiatric inpatients from the national Hospital Morbidity Survey, 69 months before and after the onset of the economic crisis (April 2008), were analyzed. Age-adjusted psychiatric (ICD9 290-319) hospital discharge rates significantly increased from April 2008, matching the onset of the crisis, especially for inpatients aged 15-24 years old and to a less extend for inpatients aged 25-34 years old. Other age groups were not affected. There was a significant increase in diagnoses for disturbance of conduct and emotions, depression, neurotic and personality disorders and alcohol and drug disorders; however, diagnoses for mental retardation and organic psychosis for 15-34 years old inpatients were unaffected. Psychiatric hospital admissions abruptly increased in April 2008, coinciding with the onset of the economic crisis. We identified age groups and diagnoses affected. Increased hospitalizations were found only at the age-ranges most affected by the rise in unemployment. The diagnoses affected were those most sensitive to environmental changes.

  1. Structural Change and Economic Development in China and India

    2009-06-01

    Full Text Available The comparison of the periods of rapid economic growth in China since 1978 and India since 1992 markedly show different patterns of development and structural change. However, both countries experienced some advantages of "relative economic backwardness" and some aspects of the "fordist model of growth". China had an anticipated and deeper structural change, spurred mainly by economic reforms and the growth of the internal market in the 1980s, and, since the mid-1990s, by a very rapid penetration of its industrial products in the world market. However, a substantial part of China's exports in medium and high tech sectors are due to joint-ventures with foreign multinationals. India had a more balanced structural change and a slower insertion in the world market, although some sectors, such as software, steel, automotive and pharmaceuticals are recently increasing their share in the world markets. Owing to the huge number of micro-enterprises and the great size of the informal sector, India benefited much less than China from the economies of scale and from the third wave of the "fordist model of growth". Both countries, but in particular China, experienced negative externalities of this recent phase of rapid growth, such as higher inequalities, pollution and urban congestion.

    This paper shows that, counter-intuitively, a higher elasticity of substitution in model production function can lead to reduced economic resilience and larger vulnerability to shocks in production factor prices. This result is due to the fact that assuming a higher elasticity of substitution requires a recalibration of the production function parameters to keep the model initial state unchanged. This result has consequences for economic analysis, e.g., on the economic vulnerability to climat...

  4. The economic case for low-carbon development in rapidly growing developing world cities: A case study of Palembang, Indonesia

    2015-01-01

    Where costs or risks are higher, evidence is lacking or supporting institutions are less developed, policymakers can struggle to make the case for low-carbon investment. This is especially the case in developing world cities where decision-makers struggle to keep up with the pace and scale of change. Focusing on Palembang in Indonesia, this paper considers the economic case for proactive investment in low-carbon development. We find that a rapidly growing industrial city in a developing country can reduce emissions by 24.1% in 2025, relative to business as usual levels, with investments of USD405.6 million that would reduce energy expenditure in the city by USD436.8 million. Emissions from the regional grid could be reduced by 12.2% in 2025, relative to business as usual trends, with investments of USD2.9 billion that would generate annual savings of USD175 million. These estimates understate the savings from reduced expenditure on energy subsidies and energy infrastructure. The compelling economic case for mainstreaming climate mitigation in this developing country city suggests that the constraints on climate action can be political and institutional rather than economic. There is therefore a need for more effective energy governance to drive the transition to a low-carbon economy. - Highlights: • We evaluate the economic case for low carbon investment in a developing world city. • Cost-effective measures could reduce emissions by 24.1% relative to BAU levels. • These pay for themselves in <1 year and generate savings throughout their lifetime. • Further savings come from reduced expenditure on energy infrastructure, subsidies. • Limitations on climate action seem to be political/institutional – not economic

    The first world consists of the developed industrial countries, the second consists of rapidly developing countries, and the third of less developed, largely pre-industrial countries. The economies of most developed countries in recent years have been relatively stagnant. Most people in the developed world therefore assume that the bottom of the business cycle has arrived and that an upturn will soon be forthcoming. With the exception of the USA and Chile, which have been moderately prosperous in the last few years, the bottom has persisted for a very long time. Indeed, the developed world is not caught in a conventional business cycle, but in something quite new and different. The first world is struggling to stay at the top of countries worldwide both economically and politically, but the second world is rapidly catching up. Populations in these latter countries are both better educated and willing to work harder per unit of capital compared to people in the first world. Marketplace forces and the communication highway are increasingly bring about a scenario in which the first and second worlds will be economic peers. Faced with increased competition from the second world and a larger number of countries capable of providing foreign aid to the third world, it should be clear that the first world will turn inward and reduce its annual aid contributions to less developed countries. It is, however, in the first world's interest to promote family planning toward the goal of reduced population growth. Developed countries should insist that a substantial fraction of whatever foreign aid is provided goes toward reducing the rate of population growth. The first priority should be to make contraceptives available and promote their use worldwide. Efforts should then be taken to empower women through educational and other programs. This approach will slow population growth and improve the economic productivity of both men and women. The Third World should also seriously

    This study attemps to investiagte the causal relationship between oil consumption and economic growth in Malaysia where oil consumption and real gross domestic product have been rapidly increased in recent years. To this end, the study employs annual data covering the period 1965–2011. Tests for unit roots, co-integration, and Granger-causality based on the error-correction models are presented. The overall results support the existence of bi-directional causality between oil consumption and economic growth in Malaysia. This means that an increase in oil consumption directly affect economic growth. Thus, in order not to make an adverse effect on economic growth, Malaysia should endeavor to overcome the constraints on oil consumption. Moreover, it appears that economic growth induces oil consumption. - Highlights: • We examine the causality between oil consumption and economic growth in Malaysia. • We employed the annual data covering the period 1965–2011. • We estimated error-correction models to test for the direction of causality. • We found that there is bi-directional causality between the two

    To examine the influence of China's economic reforms on population health and regional mortality rates. Longitudinal study measuring the mortality trends and their regional variations. Using data from the three most recent national censuses, we used the model life table to adjust the mortality levels within the population for each census, and to calculate life expectancy. We then examined the variation in patterns of mortality and population health by economic status, region and gender from 1980-2000. Life expectancy varied with economic status, province, and gender. Results showed that, although life expectancy in China had increased overall since the early 1980s, regional differences became more pronounced. Life expectancy for populations who live in the eastern coastal provinces are greater than those in the western regions. Differences in life expectancy are primarily related to differences in regional economic development, which in turn exacerbate regional health inequalities. Therefore, it is necessary to improve economic development in less developed regions and to improve health policies and the public health system that address the needs of everyone.

    Full Text Available The article is devoted to the problems of using fiscal levers to regulate the national economy competitiveness. What kind of tax levers should be used in order to increase the competitiveness of the national economy is justified. Taxes are the main source of fiscal revenue of the country, which depends on the inherent principles of optimizing the tax system, determined Ukraine's withdrawal from the crisis and raising the country's competitiveness. It is proposed differentiation in income tax rates, depending on whether the company is engaged in innovation and investment activity or not. Changing the rate of value added tax in a downward will reduce the revenue of the country. For enterprises that are not exporting products to decrease the amount of working capital for a certain period Fiscal policy that promotes the removal of the country's financial and economic crisis and the increasing competitiveness of the state, should be challenging. In order to implement incentive effects of taxes set forth in the tax code, we propose a linear programming model of the budget (revenue and expenditure . Building the economic and mathematical optimization model with possible actions challenging the tax factors of individual taxes and the possibilities of using the proceeds of certain taxes on certain items of expenditure budget.

    Full Text Available New information technologies have led to the rapid and effective growth of social networks. The amount of data produced by social networks has increased the value of the big data concept, which is one of the popular current phenomena. The immediate or unpredictable effects of a wide array of economic activities on large masses and the reactions to them can be measured by using social media platforms and big data methods. Thus, it would be extremely beneficial to analyze the harmful environmental and social impacts that are caused by unsustainable business applications. As social networks and big data are popular realms currently, their efficient use would be an important factor in sustainable economic development. Accurate analysis of people’s consumption habits and economic tendencies would provide significant advantages to companies. Moreover, unknown consumption factors that affect the economic preferences of individuals can be discovered and economic efficiency can be increased. This study shows that the numerous solution opportunities that are provided by social networks and big data have become significant tools in dynamic policy creation by companies and states, in solving problems related to women’s rights, the environment, and health.

    Full Text Available Since the period of openness in China, laid the foundation for more than 30 years ago, he has made remarkable progress in increasing incomes and reducing absolute poverty. However, they are caused by rising inequality. It should be noted that the rise in inequality was seen almost everywhere in the world over the past two decades. Growing dissatisfaction with the quality of economic growth is often seen in favor of certain groups more than the general population. This is clearly reflected in the growth of inequality between different groups - the rich are getting richer faster than the poor. The economic literature attributes this mainly to globalization, technological change, skills-based, and reduce the "power" of the workers. Growth model, which accompanies the last three decades to China, included a trade-off between high growth (and subsequent reduction of absolute poverty and worsening inequality. The government of China has recognized this problem and taken active steps to reduce the gap incomes and standards of living in the city and rural areas, which have already brought the first results.DOI: http://dx.doi.org/10.12731/2218-7405-2013-10-16

  12. Rapid population growth.

    Science.gov (United States)

    1972-01-01

    At the current rate of population growth, world population by 2000 is expected to reach 7 billion or more, with developing countries accounting for some 5.4 billion, and economically advanced nations accounting for 1.6 billion. 'Population explosion' is the result of falling mortality rates and continuing high birth rates. Many European countries, and Japan, have already completed what is termed as demographic transition, that is, birth rates have fallen to below 20 births per 1000 population, death rates to 10/1000 population, and annual growth rates are 1% or less; annual growth rates for less developed countries ranged from 2 to 3.5%. Less developed countries can be divided into 3 groups: 1) countries with both high birth and death rates; 2) countries with high birth rates and low death rates; and 3) countries with intermediate and declining birth rates and low death rates. Rapid population growth has serious economic consequences. It encourages inequities in income distribution; it limits rate of growth of gross national product by holding down level of savings and capital investments; it exerts pressure on agricultural production and land; and it creates unemployment problems. In addition, the quality of education for increasing number of chidren is adversely affected, as high proportions of children reduce the amount that can be spent for the education of each child out of the educational budget; the cost and adequacy of health and welfare services are affected in a similar way. Other serious consequences of rapid population growth are maternal death and illness, and physical and mental retardation of children of very poor families. It is very urgent that over a billion births be prevented in the next 30 years to reduce annual population growth rate from the current 2% to 1% per year.

    This article investigated the spatiotemporal variation of landscape ecological risk in Dantu District of Zhenjiang City with statistical method based on the ETM remote sensing data in 2000 and 2005, and the TM remote sensing data in 2010, and quantitative index of regional ecological risk assessment was established with the employment of landscape index, so as to enhance the ecosystem management, prevent and reduce the regional ecological risk in southern Jiangsu with rapid economic development. The results showed that the fragmentations, divergence, and ecological losses of natural landscape types, such as forestland, wetland, waters, etc., were deteriorated with the expansion of built-up lands from 2000 to 2010. The higher ecological risk zone took up 5.7%, 9.0%, and 10.2% of the whole region in 2000, 2005, and 2010, respectively, which mainly distributed in the plain hilly region. During the study period, the area aggravating to the higher ecological risk zone was approximately 296.2 km2, 48% of the whole region. The ecological risk rose up in most of the region. The interference of rapid economic development to landscape patterns was even more intensive, with obvious spatial differences in ecological risk distribution. The measures of exploiting resources near the port, utilizing natural wetlands, constructing industrial parks, and rapid urbanization, etc., intensified the ecological risk and accelerated the conversion rate. Prompt strategies should be established to manage the ecological risk of this region.

  14. Bifurcations of a class of singular biological economic models

    2009-01-01

    This paper studies systematically a prey-predator singular biological economic model with time delay. It shows that this model exhibits two bifurcation phenomena when the economic profit is zero. One is transcritical bifurcation which changes the stability of the system, and the other is singular induced bifurcation which indicates that zero economic profit brings impulse, i.e., rapid expansion of the population in biological explanation. On the other hand, if the economic profit is positive, at a critical value of bifurcation parameter, the system undergoes a Hopf bifurcation, i.e., the increase of delay destabilizes the system and bifurcates into small amplitude periodic solution. Finally, by using Matlab software, numerical simulations illustrate the effectiveness of the results obtained here. In addition, we study numerically that the system undergoes a saddle-node bifurcation when the bifurcation parameter goes through critical value of positive economic profit.

    2014-01-01

    A key part of any assessment of the global value of crop biotechnology in agriculture is an examination of its economic impact at the farm level. This paper follows earlier annual studies which examined economic impacts on yields, key costs of production, direct farm income and effects, and impacts on the production base of the four main crops of soybeans, corn, cotton and canola. The commercialization of genetically modified (GM) crops has continued to occur at a rapid rate, with important changes in both the overall level of adoption and impact occurring in 2012. This annual updated analysis shows that there have been very significant net economic benefits at the farm level amounting to $18.8 billion in 2012 and $116.6 billion for the 17-year period (in nominal terms). These economic gains have been divided roughly 50% each to farmers in developed and developing countries. GM technology have also made important contributions to increasing global production levels of the four main crops, having added 122 million tonnes and 230 million tonnes respectively, to the global production of soybeans and maize since the introduction of the technology in the mid-1990s.

  17. How Taxes and Spending on Education Influence Economic Growth in Poland

    Directory of Open Access Journals (Sweden)

    Michał Konopczyński

    2014-09-01

    Full Text Available This paper investigates the relationship between economic growth in Poland and four types of taxes and human capital investment. We primarily rely on an exogenous growth model that merges the Mankiw-Romer-Weil model, augmented with learning-by-doing and spillover-effects, with selected elements from the literature on optimal taxation. We demonstrate that in the period 2000-2011, economic growth in Poland was primarily due to a rapid increase in the human capital stock (at a rate of 5% per annum and only secondarily due to the accumulation of productive capital (2.7% annually. Simulations of tax cuts suggest that income taxes and consumption taxes restrict economic growth equally heavily. Simultaneously reducing all tax rates by 5 percentage points (pp in Poland should increase annual GDP growth by approximately 0.4 pp. Increasing spending on education by 1 pp of GDP would increase the growth rate by approximately 0.3 pp.

    Full Text Available In our community, many structural problems unresolved well, especially in social and economic life. Seeing this reality, the Church needs to have a sensitivity and a strong commitment to encourage cooperation of some parties to empower people, especially its congregation. Congregation of the Church, especially the poor need to be raised and empowered to pursue their own welfare through economic business. One manifestation of the Church's task is to empower the community-based and to revitalize its role more focused on optimizing the institution of community economy. For that, it is important to use the Model of Empowerment of Congregation-Based Community Economic in form of business partnership. The success of congregation economic empowerment lies in the motivation and orientation of the actors themselves, where the Church is expected to seriously fight.

  1. Rapid thermal conditioning of sewage sludge

    Science.gov (United States)

    Zheng, Jianhong

    Rapid thermal conditioning (RTC) is a developing technology recently applied to sewage sludge treatment. Sludge is heated rapidly to a reaction temperature (up to about 220sp°C) under sufficient pressure to maintain the liquid phase. Reaction is quenched after 10 to 30 seconds when the mixture of sludge and steam pass through a pressure let-down valve. This process reduces the amount of sludge requiring land disposal, eliminates the need for polymer coagulant, improves dewaterability, increases methane production, and further reduces the concentration of pathogens. The odor problem associated with traditional thermal conditioning processes is largely minimized. Ammonia removal is readily integrated with the process. For this research, a pilot unit was constructed capable of processing 90 liters of sludge per hour. Over 22 runs were made with this unit using sludge from New York City Water Pollution Control Plants (WPCP). Sludges processed in this equipment were tested to determine the effect of RTC operating conditions on sludge dewaterability, biodegradability, and other factors affecting the incorporation of RTC into wastewater treatment plants. Dewaterability of thermally conditioned sludge was assessed for cetrifugeability and filterability. Bench scale centrifugation was used for evaluating centrifugeability, pressure filtration and capillary suction time (CST) for filterability. A mathematical model developed for centrifuge dewatering was used to predict the effect of RTC on full scale centrifuge performance. Particle size distribution and solids density of raw and treated PDS were also analyzed. An observed increase in sludge solids density at least partially explains its improved centrifugeability. An investigation of thermally conditioned amino acids showed that the L-isomer is highly biodegradable while the D-isomers are generally less so. Glucose is highly biodegradable, but rapidly becomes refractory as thermal conditioning time is lengthened. This

    Full Text Available The aim of the article is the studying of the trends of development and economic efficiency of sugar beet production (using the example of agricultural enterprises of Rokytne district of Kyiv region and an attempt to outline the directions for improvement of the situation in the sugar beet industry. As a result of the research, the dynamics of development and economic efficiency of sugar beet production at farms of Rokytne district of Kyiv region is analyzed, and the break-even volume of sugar beet production by agrarian enterprises of Kiev region and an individual enterprise of Rokytne district is determined. Particular attention is paid to the dynamics of profitability of sugar beet production in the period from 2011 to 2015. The main problems hindering the development of sugar beet production are identified, namely, the lack of sales channels and high production costs. Prospects for further research in this area are to increase the economic efficiency of sugar beet production and find ways to develop this sector, provided that the production is properly organized, the manufacturing process is followed, the fertilizers are properly used, the seeds are chosen correctly, advanced technologies and high-performance equipment are applied, etc.

  3. The ethics and economics of pharmaceutical pricing.

    Parker-Lue, Sara; Santoro, Michael; Koski, Greg

    2015-01-01

    The cost of drugs is a major and rapidly rising component of health-care expenditures. We survey recent literature on the ethics and economics of skyrocketing pharmaceutical prices and find that advances in economic research have increased the sharpness and focus of the ethically based calls to increase access by modifying patent protection and reducing prices. In some cases, research supports ethical arguments for broader access. Other research suggests that efforts to broaden access result in unintended consequences for innovation and the medical needs of patients. Both ethicists and economists need to be more cognizant of the real clinical settings in which physicians practice medicine with real patients. Greater cross-disciplinary interaction among economists, ethicists, and physicians can help reduce the disjunction between innovation and access and improve access and patient care. This dialogue will impact private industry and may spur new multistakeholder paradigms for drug discovery, development, and pricing.

    Since the 1980s, Chinese economy grew rapidly. With the rapid economic growth, Chinese energy consumption sharply increased. The relation between Chinese energy consumption and economic growth is focused on, and many researchers have studied this issue by applying the methods such as granger causality test. However, the results just reveal the relation in a very long period. In this paper, the history of Chinese economy is divided into four periods. And the relation between Chinese energy consumption and economic growth is examined by applying grey incidence analysis, which is one of the most important methods of grey system theory which can be applied to solve the problems with small samples. The results show that the relations in different periods are not the same. The degree of grey incidences between total energy consumption and values added of secondary industry is larger, and the degree of grey incidences between GDP and consumption of coal is larger too. And the policy implications of these results are explained.

  10. Mindfulness training increases cooperative decision making in economic exchanges: Evidence from fMRI.

    2016-09-01

    Emotions have been shown to exert influences on decision making during economic exchanges. Here we investigate the underlying neural mechanisms of a training regimen which is hypothesized to promote emotional awareness, specifically mindfulness training (MT). We test the hypothesis that MT increases cooperative economic decision making using fMRI in a randomized longitudinal design involving 8weeks of either MT or active control training (CT). We find that MT results in an increased willingness to cooperate indexed by higher acceptance rates to unfair monetary offers in the Ultimatum Game. While controlling for acceptance rates of monetary offers between intervention groups, subjects in the MT and CT groups show differential brain activation patterns. Specifically, a subset of more cooperative MT subjects displays increased activation in the septal region, an area linked to social attachment, which may drive the increased willingness to express cooperative behavior in the MT cohort. Furthermore, MT resulted in attenuated activity in anterior insula compared with the CT group in response to unfair monetary offers post-training, which may suggest that MT enables greater ability to effectively regulate the anterior insula and thereby promotes social cooperation. Finally, functional connectivity analyses show a coupling between the septal region and posterior insula in the MT group, suggesting an integration of interoceptive inputs. Together, these results highlight that MT may be employed in contexts where emotional regulation is required to promote social cooperation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Ivanova S.

    2018-01-01

    Full Text Available Introduction. Modern business conditions and comprehensive economic globalization put the banking institutions at the forefront of the task of achieving and maintaining a high level of competitiveness both on the domestic and on the external financial markets, as banks serve as the main intermediaries in the whole complex of relationships between different economic subjects. To achieve and maintain the competitiveness of banks it is important to create an effective management mechanism, which determines the relevance of the chosen topic. Purpose. The purpose of the work is to summarize the existing theoretical aspects concerning the competitiveness of banks and develop organizational and economic approaches to its enhancement and implementation in banking practice. Results. The article generalizes the notion of competitiveness as an economic category and defines the main approaches of scientists to its interpretation. The role and importance of foreign capital in the banking system and its impact on the competitiveness of banks are considered, and the share of foreign capital in the authorized capital of banks for the period of 2008-2017 is calculated. On the basis of the comparative analysis, the impact on the competitiveness of the largest banking institutions of Ukraine on the performance indicators, such as volumes of assets, liabilities of banks and capital adequacy, was investigated. The possibility of increasing the efficiency of the mechanism of ensuring competitiveness according to the process approach is outlined. By means of the Microsoft Office Visio software system, the Bank’s own Banking Business Management business process was built to ensure the bank’s viability and its structural analysis according to the IDEF0 standard of the SADT methodology. Conclusions. The relationship between the analysis of the bank’s position and the development of its development strategy is important for the understanding and effective management

    Full Text Available This study is an attempt to assess quantitatively social and economic factors that determine vulnerability of Russian regions to natural risk, to trace the space differences of the considered factors, and to group the regions by their similarity. In order to indicate the regional differences in social and economic development, equipment condition, dangerous substances accumulation, and social trouble four the most suitable parameters were estimated, including the per capita production of Gross Regional Product (GRP, capital consumption, volume of total toxic waste, and crime rate. Increase of the first parameter causes vulnerability reducing, the increase of the last three causes its increasing. Using multidimensional cluster analysis five types of regions were found for Russia according to similarity of the considered parameters. These types are characterized with higher value of a single (rarely two chosen parameter, which seems to be sufficient enough to affect natural risks increasing in these regions in near future. Only few regions belonging to the fifth type proved to have rather high value of GRP and relatively low values of the other parameters. The negative correlation was found between a number of natural disasters (ND and the per capita GRP in case when some parameters reached anomalously high value. The distinctions between regions by prevailing different parameters, which result in natural risk increasing, help risk management to find directions where to focus on.

    In this study, we attempt to quantify the benefits of various options of grid flexibility by measuring their impact on two measures: economic carrying capacity and system costs. Flexibility can increase economic carrying capacity and reduce overall system costs. In some cases, options that provide a limited increase in economic carrying capacity can provide significant operational savings, thus demonstrating the need to evaluate flexibility options using multiple metrics. The value of flexibility options varies regionally due to different generation mixes and types of renewables. The more rapid decline in PV value compared to wind makes PV more dependent on adding flexibility options, including transmission and energy storage.

    A post-World War II analysis of the potential for US economic expansion projects a continuation of the basic social and economic expectations and international relations and of the upward trend of labor input, labor productivity, and national output. How economic growth of the future will differ as a result of global changes in population and resources is examined in the context of other national objectives. The rapid increase in labor productivity during the postwar period was taken in the form of income rather than leisure. This led to a growth of goods and real per capita income as well as higher standards of living, education, and economic stability. The implications for future growth indicate the need to slow the growth of the national product in line with the rate of population growth. The improved welfare of the people should be the overall goal of which economic growth is one component. 23 tables. (DCK)

  17. The economic benefits of malaria elimination: do they include increases in tourism?

    2012-07-28

    Policy makers have speculated that one of the economic benefits of malaria elimination includes increases in foreign direct investment, particularly tourism. This study examines the empirical relationship between the demand for travel and malaria cases in two countries with large tourism industries around the time in which they carried out malaria-elimination campaigns. In Mauritius, this analysis examines historical, yearly tourist arrivals and malaria cases from 1978-1999, accounting for the background secular trend of increasing international travel. In Dominican Republic, a country embarking upon malaria elimination, it employs a time-series analysis of the monthly, international tourist arrivals from 1998-2010 to determine whether the timing of significant deviations in tourist arrivals coincides with malaria outbreaks. While naïve relationships exist in both cases, the results show that the relationships between tourist arrivals and malaria cases are relatively weak and statistically insignificant once secular confounders are accounted for. This suggests that any economic benefits from tourism that may be derived from actively pursuing elimination in countries that have high tourism potential are likely to be small when measured at a national level. Rather, tourism benefits are likely to be experienced with greater impact in more concentrated tourist areas within countries, and future studies should seek to assess these relationships at a regional or local level.

    The spatiotemporal evolution of the temperature in the afterglow of point-to-plane, pulsed positive streamer discharge was measured near the anode tip and cathode surface using laser-induced predissociation fluorescence of OH radicals. The temperature exhibited a rapid increase and displayed a steep spatial gradient after a discharge pulse. The rate of temperature rise reached 84 K μs‑1 at mm, where z represents the distance from the anode tip. The temperature rise was much faster than in the middle of the gap; it was only 2.8 K μs‑1 at mm. The temperature reached 1700 K near the anode tip at s and 1500 K near the cathode surface at s, where t represents the postdischarge time. The spatial gradient reached 1280 K mm‑1 near the anode tip at s. The mechanism responsible for the rapid temperature increase was discussed, including rapid heating of the gas in the early postdischarge phase (s), and vibration-to-translation energy transfer in the later postdischarge phase (s). The high temperatures near the anode tip and cathode surface are particularly important for the ignition of combustible mixtures and for surface treatments, including solid-surface treatments, water treatments, and plasma medicine using pulsed streamer discharges.

  19. Rapid Environmental Change Drives Increased Land Use by an Arctic Marine Predator.

    Todd C Atwood

    Full Text Available In the Arctic Ocean's southern Beaufort Sea (SB, the length of the sea ice melt season (i.e., period between the onset of sea ice break-up in summer and freeze-up in fall has increased substantially since the late 1990s. Historically, polar bears (Ursus maritimus of the SB have mostly remained on the sea ice year-round (except for those that came ashore to den, but recent changes in the extent and phenology of sea ice habitat have coincided with evidence that use of terrestrial habitat is increasing. We characterized the spatial behavior of polar bears spending summer and fall on land along Alaska's north coast to better understand the nexus between rapid environmental change and increased use of terrestrial habitat. We found that the percentage of radiocollared adult females from the SB subpopulation coming ashore has tripled over 15 years. Moreover, we detected trends of earlier arrival on shore, increased length of stay, and later departure back to sea ice, all of which were related to declines in the availability of sea ice habitat over the continental shelf and changes to sea ice phenology. Since the late 1990s, the mean duration of the open-water season in the SB increased by 36 days, and the mean length of stay on shore increased by 31 days. While on shore, the distribution of polar bears was influenced by the availability of scavenge subsidies in the form of subsistence-harvested bowhead whale (Balaena mysticetus remains aggregated at sites along the coast. The declining spatio-temporal availability of sea ice habitat and increased availability of human-provisioned resources are likely to result in increased use of land. Increased residency on land is cause for concern given that, while there, bears may be exposed to a greater array of risk factors including those associated with increased human activities.

  1. STYLIZED ECONOMIC FACTS OF TRANSITION

    2017-12-01

    Full Text Available In the course of transition, former socialistic countries moved from planned to market economy. This journey typically started with sharp falls in economic activity in all transition countries, accompanied by deterioration of various social indicators. Hence, their main objective was the recovery of economic activity, i.e. increasing the economic growth rate, which in addition was supposed to enable catching up with the European developed economies. This growth movement is usually described by famous U-curve of transition. However, in spite of the efforts and reforms, all transition economies recorded various paces of recovery. This study discusses that difference, through various GDP indicators, - real GDP path, GDP growth rates path, the height of the GDP index achieved and the volatility of growth rates. Analysed in concert, these indicators suggest several other variations of the transition Ucurve, such as: the rapid-J group, the wide-U group and the L-curve group. Namely, almost three decades after the start of the transition, the differences persist, suggesting that some transition economies has not moved significantly towards catching up with the successful transition countries, or with the developed economies.

    2016-03-01

    Full Text Available Medical travel has the capacity to counter increasing costs of healthcare by creating new markets and increased revenue for health services, potentially benefiting local populations, economies and health care systems. This paper is part of a broad, comprehensive project aimed at developing a Global Health Access Policy (GHAP. It presents key issues to consider in terms of ensuring economic viability, sustainability, and limiting risk to the many stakeholders involved in the rapidly expanding industry of medical travel. The noted economic and legal barriers to medical travel are based on a synthesis of themes found in an extensive review of the available literature. Economic considerations when setting up a GHAP include a dynamic approach to pricing that is fair to the local population. Legal considerations include the implementation of international quality standards and the protection of the rights of those travelling as well as those of local populations in recipient countries. By taking into account these opportunities, the GHAP will more adequately address existing gaps in the economic and legal regulation of medical travel.

  4. Information security: where computer science, economics and psychology meet.

    Anderson, Ross; Moore, Tyler

    2009-07-13

    Until ca. 2000, information security was seen as a technological discipline, based on computer science but with mathematics helping in the design of ciphers and protocols. That perspective started to change as researchers and practitioners realized the importance of economics. As distributed systems are increasingly composed of machines that belong to principals with divergent interests, incentives are becoming as important to dependability as technical design. A thriving new field of information security economics provides valuable insights not just into 'security' topics such as privacy, bugs, spam and phishing, but into more general areas of system dependability and policy. This research programme has recently started to interact with psychology. One thread is in response to phishing, the most rapidly growing form of online crime, in which fraudsters trick people into giving their credentials to bogus websites; a second is through the increasing importance of security usability; and a third comes through the psychology-and-economics tradition. The promise of this multidisciplinary research programme is a novel framework for analysing information security problems-one that is both principled and effective.

    Rapid increase of the renewable energy share in electricity production requires optimization and flexibility of the power consumption side. Thermostatically controlled loads (TCLs) have a large potential for regulation service provision. Economic model predictive control (MPC) is an advanced...... control method which can be used to syncronize the power consumption with undispatchable renewable electricity production. Thermal behavior of TCLs can be described by linear models based on energy balance of the system. In some cases, parameters of the model may be time-varying. In this work, we present...... a modified economic MPC based on linear parameter-varying model. In particular, we provide an exact transformation from a standard economic MPC formulation to a linear program. We assume that the variables influencing the model parameters are known (predictable) for the prediction horizon of the controller...

  6. Economics and the question of low-grade heat

    1976-01-01

    This paper examines, from the viewpoint of an economist, the issues involved in the increased waste heat production generated by the rapid acceleration of electrical production and nuclear generation. It reviews some of the literature on low-grade heat - its economic considerations and ecological impact - and examines the applicability of the traditional type of analytical decision tool (cost/benefit analysis) to the efficient design of heat rejection systems. It is recognized that decisions should be made on the basis of social costs and benefits as well as purely monetary considerations. The validity and shortcomings of cost/benefit analysis are presented. It is concluded that, for energy policy planning and waste heat management, economic feasibility studies should lay out the options together with the costs and risks. (author)

  8. Methods of Economic Valuation of The Health Risks Associated with Nanomaterials

    Science.gov (United States)

    Shalhevet, S.; Haruvy, N.

    The worldwide market for nanomaterials is growing rapidly, but relatively little is still known about the potential risks associated with these materials. The potential health hazards associated with exposure to nanomaterials may lead in the future to increased health costs as well as increased economic costs to the companies involved, as has happened in the past in the case of asbestos. Therefore, it is important to make an initial estimate of the potential costs associated with these health hazards, and to prepare ahead with appropriate health insurance for individuals and financial insurance for companies. While several studies have examined the environmental and health hazards of different nanomaterials by performing life cycle impact assessments, so far these studies have concentrated on the cost of production, and did not estimate the economic impact of the health hazards. This paper discusses methods of evaluating the economic impact of potential health hazards on the public. The proposed method is based on using life cycle impact assessment studies of nanomaterials to estimate the DALYs (Disability Adjusted Life Years) associated with the increased probability of these health hazards. The economic valuation of DALY's can be carried out based on the income lost and the costs of medical treatment. The total expected increase in cost depends on the increase in the statistical probability of each disease.

    2002-12-01

    Full Text Available The purpose of this study is to provide the analytical background of North Korea's trade expansion with Western countries in the early 1970's and examine in depth the resulting impacts on the North Korean economy. Indeed, this study explores the implications of the mechanism and consequences of North Korea's increased trade with Western countries in the 1970's for the current situation of the country's trade expansion based on the rapid increase in imports and large trade deficit. As a result of researching North Korea's economic trajectory during the 1970's within this focus, this study asserts that, despite some positive aspects, North Korea's rapid increase of foreign trade in recent years possesses the immanent possibility of generating serious obstacles to the process of economic recovery. In this vein, this paper intends to explore some policy options North Korea should choose in order to create conditions conducive to economic rehabilitation and prevent the recurrence of similar situation as experienced in the 1970's.

  10. Large-scale deployment of seed treatments has driven rapid increase in use of neonicotinoid insecticides and preemptive pest management in US field crops.

    Science.gov (United States)

    Douglas, Margaret R; Tooker, John F

    2015-04-21

    Neonicotinoids are the most widely used class of insecticides worldwide, but patterns of their use in the U.S. are poorly documented, constraining attempts to understand their role in pest management and potential nontarget effects. We synthesized publicly available data to estimate and interpret trends in neonicotinoid use since their introduction in 1994, with a special focus on seed treatments, a major use not captured by the national pesticide-use survey. Neonicotinoid use increased rapidly between 2003 and 2011, as seed-applied products were introduced in field crops, marking an unprecedented shift toward large-scale, preemptive insecticide use: 34-44% of soybeans and 79-100% of maize hectares were treated in 2011. This finding contradicts recent analyses, which concluded that insecticides are used today on fewer maize hectares than a decade or two ago. If current trends continue, neonicotinoid use will increase further through application to more hectares of soybean and other crop species and escalation of per-seed rates. Alternatively, our results, and other recent analyses, suggest that carefully targeted efforts could considerably reduce neonicotinoid use in field crops without yield declines or economic harm to farmers, reducing the potential for pest resistance, nontarget pest outbreaks, environmental contamination, and harm to wildlife, including pollinator species.

    Full Text Available Risk is a reality of the economic environment, with consequences which cannot always be foreseen or anticipated. Risk management becomes more stringent as potential exo/endogenous vulnerability factors are rapidly increasing. Identifying risk areas, structuring risk factors and defining their probability, optimal management of resources in order to reduce risk factors, creating alternatives for each high-probability risk factor are part of project risk management. Risk is quantified through probability and incidence and is assessed using quantitative and qualitative methods.

    Full Text Available Mainland China has undergone profound changes dating back to the nineteenth century, including a contemporary period of rapid modernization that began in the 1980s. The result has been dramatic social, cultural, and economic shifts impacting the daily lives of Chinese people. In this paper, we explore the psychological implications of sociocultural transformation in China, emphasizing two central themes. First, rising individualism: findings from social and developmental psychology suggest that China’s rapid development has been accompanied by ever-increasing adherence to individualistic values. Second, rising rates of depression: findings from psychiatric epidemiology point to increasing prevalence of depression over this same time period, particularly in rural settings. We argue that links between sociocultural and psychological shifts in China can be usefully studied through a cultural psychology lens, emphasizing the mutual constitution of culture, mind, and brain. In particular, we note that the link between social change, individualism, and rising mental illness deserves careful attention. Our review suggests that shifting values and socialization practices shape emotion norms of concealment and display, with implications for depressive symptom presentation. The challenge comes with interpretation. Increasing prevalence rates of depression may indeed be a general response to the rapidity of sociocultural change, or a specific consequence of rising individualism—but may also result from increasingly ‘Western’ patterns of symptom presentation, or improvements in diagnostic practice. We conclude by considering the challenges posed to standard universal models of psychological phenomena.

    Full Text Available Environmental pollution represents one of the problems that humanity is facing right now, problems that create a series of economic, ecologic and social consequences. This paper wishes to identify by presenting concrete data, some of the negative effects that occurred as a result of the increase of pollution on global scale, for example like the rise of global temperature. Starting with the industrial revolution but especially with the increase of the population’s needs, desires, interests that occurred during the last decades, environmental pollution intensified to an extent that we could even consider alarming. A main effect which can be easily observed by each and every person without the need to perform measurements, is the climate warming which has a series of consequences, like for example: drought, natural disasters, decrease in agricultural production, fires (especially wildfires which reduce the population of wild animals, etc. So the effects of global warming are not just ecologic but also economic and social. Another aspect analyzed in this paper is the rise of the seas’ and oceans’ temperature which inevitably results in the decrease of the population of fish and aquatic animals. The melting of glaciers is another negative effect of the climate warming which is discussed in this paper, effect which is responsible for numerous floods that result from the rise of the sea levels causing numerous damages, the most affected people being those living in the vicinity of waters. During floods, phenomenon which occurs more and more often, drainage channels are overused many times not being able to handle the huge quantities of water, thus favoring the multiplication and spreading of rodents. There are evidences showing that the number of cases of diseases transmitted by rodents increases during natural disasters, which occur more and more often during the last decades.

    Milborrow, D.J.

    1995-01-01

    The economics of wind energy are changing rapidly, with improvements in machine performance and increases in size both contributing to reduce costs. These trends are examined and future costs assessed. Although the United Kingdom has regions of high wind speed, these are often in difficult terrain and construction costs are often higher than elsewhere in Europe. Nevertheless, wind energy costs are converging with those of the conventional thermal sources. At present, bank loan periods for wind projects are shorter than for thermal plant, which means that energy prices are higher. Ways of overcoming this problem are explored. It is important, also, to examine the value of wind energy. It is argued that wind energy has a higher value than energy from centralized plant, since it is fed into the low-voltage distribution network. (Author)

    Full Text Available Although the recent global financial crisis has stimulated a vast amount of research on the impact of public debt on economic growth and also increasingly on the role of private credit, the total levels of indebtedness of an economy have largely been ignored. This paper studies the impact of the total level of and increases in debt-to-GDP on economic growth for 26 developed countries in the short, medium and longer term. We analyse whether we can predict the future level of growth, simply by looking at the total level of debt, or increases in that debt level. We find that there is a negative correlation between high levels of debt and short term economic growth, but that this effect tapers in the medium and long term. Similarly, we find that rapid debt accumulation is negatively related to economic growth over the short term, the impact is less pronounced over the medium term and is non-existent over the long term.

    Increasing college degree attainment for students from disadvantaged backgrounds is a prominent component of numerous state and federal legislation focused on higher education. In 1999, the National Science Foundation (NSF) instituted the "Computer Science, Engineering, and Mathematics Scholarships" (CSEMS) program; this initiative was designed to provide greater access and support to academically talented students from economically disadvantaged backgrounds. Originally intended to provide financial support to lower income students, this NSF program also advocated that additional professional development and advising would be strategies to increase undergraduate persistence to graduation. This innovative program for economically disadvantaged students was extended in 2004 to include students from other disciplines including the physical and life sciences as well as the technology fields, and the new name of the program was Scholarships for Science, Technology, Engineering and Mathematics (S-STEM). The implementation of these two programs in Louisiana State University (LSU) has shown significant and measurable success since 2000, making LSU a Model University in providing support to economically disadvantaged students within the STEM disciplines. The achievement of these programs is evidenced by the graduation rates of its participants. This report provides details on the educational model employed through the CSEMS/S-STEM projects at LSU and provides a path to success for increasing student retention rates in STEM disciplines. While the LSU's experience is presented as a case study, the potential relevance of this innovative mentoring program in conjunction with the financial support system is discussed in detail.

    2014-04-01

    Full Text Available This paper empirically examines the relationship between oil consumption, nuclear energy consumption, oil price and economic growth in four emerging economies (Russia, China, South Korea, and India over the period from 1965 to 2010. Applying a modified version of the granger causality test developed by Toda and Yamamoto, we find that the level of world crude oil prices (WTI plays a crucial role in determining the economic growth in the investigated countries. The results suggest that there is a unidirectional causality running from real GDP to oil consumption in China and South Korea, while bidirectional relationship between oil consumption and real GDP growth appears in India. Furthermore, the results propose that while nuclear energy stimulates economic growth in both South Korea and India, the rapid increase in China economic growth requires additional usage of nuclear energy.

    This is a progress report on the first phase of a project to measure the economic impacts of a rapidly changing U.S. target base. The purpose of the first phase is to designate and test the macroeconomic impact analysis model. Criteria were established for a decision-support model. Additional criteria were defined for an interactive macroeconomic impact analysis model. After a review of several models, the Economic Impact Forecast System model of the U.S. Army Construction Research Laboratory was selected as the appropriate input-output tool that can address local and regional economic analysis. The model was applied to five test cases to demonstrate its utility and define possible revisions to meet project criteria. A plan for EIFS access was defined at three levels. Objectives and tasks for scenario refinement are proposed.

  2. Economic impact from unrestricted spread of potato cyst nematodes in australia.

    Hodda, M; Cook, D C

    2009-12-01

    ABSTRACT Potato cyst nematodes (PCN) (Globodera spp.) are quarantine pests with serious potential economic consequences. Recent new detections in Australia, Canada, and the United States have focussed attention on the consequences of spread and economic justifications for alternative responses. Here, a full assessment of the economic impact of PCN spread from a small initial incursion is presented. Models linking spread, population growth, and economic impact are combined to estimate costs of spread without restriction in Australia. Because the characteristics of the Australian PCN populations are currently unknown, the known ranges of parameters were used to obtain cost scenarios, an approach which makes the model predictions applicable generally. Our analysis indicates that mean annual costs associated with spread of PCN would increase rapidly initially, associated with increased testing. Costs would then increase more slowly to peak at over AUD$20 million per year approximately 10 years into the future. Afterward, this annual cost would decrease slightly due to discounting factors. Mean annual costs over 20 years were $18.7 million, with a 90% confidence interval between AUD$11.9 million and AUD$27.0 million. Thus, cumulative losses to Australian agriculture over 20 years may exceed $370 million without action to prevent spread of PCN and entry to new areas.

    Designing a desirable increasing block tariff for the residential gas retail market has been a challenging task for regulated utilities, especially in China. To deal with such problems, in this paper, we establish an agent-based, computational economics system to provide a formal evaluation of the direct and indirect influences of several issued increasing block tariffs in the residential gas market. Moreover, a comprehensive demand response behaviour model has been improved in term of price elasticity, while still coping with income levels and complex social environment. We also compute and compare the outcomes of several increasing block tariffs with the initial flat tariff by running the system on a test-case using real-world data from a middle-scale gas retail market in Wuhan. The results indicate that there is an appropriate increasing block gas tariff scheme that has greater ability to improve social equity while still ensuring operator revenue and promoting gas conservation. In order to offset the limitations of the proposed increasing block tariffs, the regulator should adopt some complementary measures, such as applying appropriate policies targeting the intended consumers, and allowing large families to obtain extra allowance of volume. - Highlights: •Analyse the influence of increasing block tariffs in residential gas sector. •An agent-based computational economics system is utilised for policy analysis. •Increasing block tariff can generate revenue while still promote gas conservation. •The increasing subsidy for low income household can improve the social equity.

    2009-09-15

    In this paper we examine the causal relationship between electricity consumption and economic growth in South Africa. We incorporate the employment rate as an intermittent variable in the bivariate model between electricity consumption and economic growth - thereby creating a simple trivariate causality framework. Our empirical results show that there is a distinct bidirectional causality between electricity consumption and economic growth in South Africa. In addition, the results show that employment in South Africa Granger-causes economic growth. The results apply irrespective of whether the causality is estimated in the short-run or in the long-run formulation. The study, therefore, recommends that policies geared towards the expansion of the electricity infrastructure should be intensified in South Africa in order to cope with the increasing demand exerted by the country's strong economic growth and rapid industrialisation programme. This will certainly enable the country to avoid unprecedented power outages similar to those experienced in the country in mid-January 2008. (author)

    Health economic studies provide information to decision makers for efficient use of available resources for maximizing health benefits. Economic evaluation is one part of health economics, and it is a tool for comparing costs and consequences of different interventions. Health technology assessment is a technique for economic evaluation that is well adapted by developed countries. The traditional classification of economic evaluation includes cost-minimization, cost-effectiveness analysis, cost-utility analysis, and cost-benefit analysis. There has been uncertainty in the conduct of such economic evaluations in India, due to some hesitancy with respect to the adoption of their guidelines. The biggest challenge in this evolutionary method is lack of understanding of methods in current use by all those involved in the provision and purchasing of health care. In some countries, different methods of economic evaluation have been adopted for decision making, most commonly to address the question of public subsidies for the purchase of medicines. There is limited evidence on the impact of health insurance on the health and economic well-being of beneficiaries in developing countries. India is currently pursuing several strategies to improve health services for its population, including investing in government-provided services as well as purchasing services from public and private providers through various schemes. Prospects for future growth and development in this field are required in India because rapid health care inflation, increasing rates of chronic conditions, aging population, and increasing technology diffusion will require greater economic efficiency into health care systems.

    2012-01-01

    Achieving the 80% decrease in carbon-dioxide emissions until 2050, which is the primary goal of the European Union's long-term energy policy, assumes, inter alia, that the electricity part of the system will be able to produce at least 96% of electricity from renewable sources. Moreover, the power system in the widest sense of the word should significantly increase its energy efficiency. Such tremendously ambitious goals, which may as well seem almost unattainable from today's perspective, will certainly require hefty capital investments in plants based on clean technologies, thus, the costs of pollution externalities will not be avoidable anymore. They will have to be bore by the society through substantial increase in energy prices relative to other products and services. Today's subvention schemes, which support current development of renewable sources, will have to be completely abandoned until such a distant future as 2050 is. The power system will have to become self-sustainable in an economic sense. This work pertains to economic challenges which face the power system in a forthcoming processes of rapid decarbonization, as well as to some widely-spread blunders about them.(author)

    Based on the ideology of macro environmental economics, a function of environmental pressure represented by pollutant emission was built, and the relative importance of the driving factors in the dynamic changes of the relationships between economic growth and environmental pressure in Gansu Province in 1990 - 2005 was analyzed by using structural decomposition analysis (SDA) model combining with 'refined Laspeyres' method. In the study period, the environmental pressure in the Province was mainly caused by the emission of waste gases and solids in the process of economic growth, and showed a rapid increasing trend at the late stage of the period. Population factor had less impact on the increase of this environmental pressure, while economic growth factor had obvious impact on it. Technological progress did mitigate, but could not offset the impact of economic growth factor, and the impacts of economic growth and technological factors on the environmental pressure differed with the kinds of pollutants.

    Ecotourism is one of the fast-growing sectors especially in the developing country as a source of revenue. To get a sustainable development of ecotourism, it needs broad and comprehensive effort from central government and local government, perfect example in that regards in Indonesia is Bali and Lombok. For another area in Indonesia like Kei Islands which located in two administrative governments have a major problem to build a sustainable nature-based tourism because of the location of this area to the major cities in the country makes the travel cost is high. This situation makes the role of local community as the backbone of the growth and development of nature-based tourism is critical. By using structural equation modeling (SEM), we constructed a model to enhance local community perception on economic valuation of ecotourism spots in the area. Results showed that perceived quality as the mediation driven by the intensity of appearance on national television and the internet could increase community attachment to increase willingness to pay from the local community on ecotourism in Kei islands. Also, the result also indicated that WTP value for the local community on ecotourism in Kei Islands was 10.81 per trip, with average trip per month was 1 to 4 times.

  12. Wind energy economics

    1995-01-01

    The economics of wind energy have improved rapidly in the past few years, with improvements in machine performance and increases in size both contributing to reduce costs. These trends are examined and future costs assessed. As bank loan periods for wind projects are shorter than for thermal plant, the effect on the price of wind energy is discussed. It is argued that wind energy has a higher value than that of centralised plant, since it is fed into the low voltage distribution network and it follows that the price of wind energy is converging with its value. The paper also includes a brief review of the capacity credit of wind plant and an assessment of the cost penalties which are incurred due to the need to hold extra plant on part load. These penalties are shown to be small. (author)

    Full Text Available Tourism as a phenomenon of social life is a derivative of social development. Its appearance is attributed to the industrial stage of human development, which was inherent in the accelerated development of the productive forces, deepening division of labour, development of urbanization processes. Accelerated innovation changes related to scientific and technological progress contributed to the overall socio-economic development of certain countries, improve the living standards of their populations, changed the nature of work, method and way of life, especially evident in the XX century. Urbanization and changes in the settlement system, post-industrial phase of economic development, deepening comprehension of environmental issues and global dimension of humanity, humanization of all spheres of public life. The increase in tourist flows in all regions complicates the management of enterprises, schemes of partnership in the process in tourism, which, among other things, is accompanied by rising levels of consumer education, and therefore their quality requirements for end tourism product, the rapid increase in supply, there is a need to study the characteristics of consumer behaviour, search for existing reserves to build capacity of individual enterprises, isolation and effective use of effective methods and tools of influence on consumer choice of consumers. Development and implementation of an effective mechanism of formation of market supply needs an assessment of consumer behaviour on quantitative and qualitative indicators. The rapid development of tourism, of course, helps determine the types and methods of calculating these indicators. These problems and targeted research are considered in this article. The subject of research is the concept and tools of analysis, mathematical modelling of the economic structure of society in dynamic tourist services. Research methodology is economic and mathematical models, algorithms and processes

    Tools for projecting crop productivity under a range of conditions, and assessing adaptation options, are an important part of the endeavour to prioritize investment in adaptation. We present ensemble projections of crop productivity that account for biophysical processes, inherent uncertainty and adaptation, using spring wheat in Northeast China as a case study. A parallel 'vulnerability index' approach uses quantitative socio-economic data to account for autonomous farmer adaptation. The simulations show crop failure rates increasing under climate change, due to increasing extremes of both heat and water stress. Crop failure rates increase with mean temperature, with increases in maximum failure rates being greater than those in median failure rates. The results suggest that significant adaptation is possible through either socio-economic measures such as greater investment, or biophysical measures such as drought or heat tolerance in crops. The results also show that adaptation becomes increasingly necessitated as mean temperature and the associated number of extremes rise. The results, and the limitations of this study, also suggest directions for research for linking climate and crop models, socio-economic analyses and crop variety trial data in order to prioritize options such as capacity building, plant breeding and biotechnology.

    Accurate assessments of the population exposed to seismic hazard are crucial in seismic risk mapping. Recent rapid urbanization in China has resulted in substantial changes in the size and structure of the population exposed to seismic hazard. Using the latest population census data and seismic maps, this work investigated spatiotemporal changes in the exposure of the population in the most seismically hazardous areas (MSHAs) in China from 1990 to 2010. In the context of rapid urbanization and massive rural-to-urban migration, nearly one-tenth of the Chinese population in 2010 lived in MSHAs. From 1990 to 2010, the MSHA population increased by 32.53 million at a significantly higher rate of change (33.6%) than the national average rate (17.7%). The elderly population in MSHAs increased by 81.4%, which is much higher than the group’s national growth rate of 58.9%. Greater attention should be paid to the demographic changes in earthquake-prone areas in China.

  19. Economics of nuclear and renewables

    Khatib, Hisham; Difiglio, Carmine

    2016-01-01

    This paper provides an assessment of the economic challenges faced by both nuclear power and “new” renewable electricity technologies. The assessment reflects the need to incorporate new renewables into power grids and issues faced in dispatching power and their effect on traditional electricity technologies as well as the need for transmission extension and/or grid reinforcement. Wider introduction of smart grids and the likely demise of nuclear in some OECD countries are bound to enhance the future prospects for new renewables. However, their immediate future expansion will depend on continued subsidies, which are becoming difficult to sustain in present economic circumstances. Development of large energy storage facilities and carbon pricing could significantly enhance future renewable energy prospects. Correspondingly, expanding renewable energy, in spite of their popularity with some governments and sections of the public, is likely to face challenges which will slow their present rapid progress. Nuclear is now shied away from in many industrialized countries and having mixed prospects in developing economies. In many instances, it suffers from high initial costs, long lead times and often excessive construction delays. Nuclear power also faces challenging risks – investment as well as regulatory. In contrast to renewables, its share of global energy consumption is declining. - Highlights: •Renewables are increasing their energy share. •Renewables system cost is higher than their production cost. •Nuclear share is not increasing and their costs are not reduced. •Discount rate and subsidies are important in economics of renewables and nuclear.

    There has been a rapid increase in the use of targeted oral anticancer medications (OAMs) in the past decade. As OAMs are often expensive, economic consideration play a significant role in the decision to prescribe, receive or cover them. This paper performs a systematic review of costs or budgetary impact of targeted OAMs to better understand their economic impact on the healthcare system, patients as well as payers. We present our review in a summary table that describes the method and main findings, take into account multiple factors, such as country, analytical approach, cost type, study perspective, timeframe, data sources, study population and care setting when we interpret the results from different papers, and discuss the policy and clinical implications. Our review raises a concern regarding the role of sponsorship on findings of economic analyses as the vast majority of pharmaceutical company-sponsored studies reported cost advantages toward the sponsor's drugs.

  1. Rapid Urbanization and Implications for Flood Risk Management in Hinterland of the Pearl River Delta, China: The Foshan Study

    2008-03-01

    Full Text Available The purpose of this paper is to examine the linkage between rapid urbanization and flood risk in the hinterlands of the Pearl River Delta, P.R. China. Foshan, a typical hinterland city in the Pearl River Delta region, was selected as a case study. Land use and cover change in Foshan during 1988-2003 was analyzed using remote sensing and geographic information system (GIS techniques. Furthermore, analysis on historical hydrological data during 1962-2005 was performed. Results show that rapid urbanization has resulted in losses of farmland, forest and shrub since 1988. In addition, in order to compensate or offset the loss of farmland due to rapid urban expansion, more than 30 % of the forest and 20 % of the shrub areas were transformed into farmlands. Inevitably, both the urban and agricultural lands increased the pressure on the drainage systems. Furthermore, over the past decades human activities such as dredging up the floodways, excavating sand and building water facilities in the rivers, significantly changed the hydrological conditions, and therefore impaired the rivers’ capacity to buffer floods. Lessons from the Foshan case implied that, in addition to natural processes, human activities driven by socio-economic factors should be considered responsible for the recently increasing level of flood risks. Both economically and environmentally, it is irrational and impractical to encourage encroachment of lands vulnerable to floods. It is also realistic and urgent to effectively prevent and control the adverse ecological consequences of urbanization and economic activities for building their wealth and prominence.

    The energy consumption in Korea has greatly increased along with its rapid economic growth and industrialization since the 1970s. Total energy consumption increased at an average annual growth rate. Due to the lack of domestic energy resources, however, the overseas dependence rate of energy consumption has continuously increased. Also Climate change, resulting from increases in greenhouse gas emissions (GHG), is considered one of the biggest environmental dangers facing the world today. The objective and approach of this study are to compare the different types of scenarios in terms of the power plant type and CO 2 emission from each power plant. We estimated cost of electricity generation using fuel cost, O and M cost(Operation and Maintenance Cost) and CO 2 emission

    There is a global epidemic of overweight and obesity; however, this rate of increase is even greater in some low- and middle-income countries (LMIC). South Africa (SA) is undergoing rapid socioeconomic and demographic changes that have triggered a rapid nutrition transition. The paper focuses on the recent rate of change of body mass index (BMI) among children, adolescents and young adults, further stratified by key sociodemographic factors. We analysed mean BMI of 28 247 individuals (including children) from 7301 households by age and year, from anthropometric data from four national cross-sectional (repeated panel) surveys using non-linear fitted curves and associated 95% confidence intervals. From 2008 to 2015, there was rapid rise in mean BMI in the 6-25 age band, with the highest risk (3-4+ BMI unit increase) among children aged 8-10 years. The increase was largely among females in urban areas and of middle-high socioeconomic standing. Prominent gains were also observed in certain rural areas, with extensive geographical heterogeneity across the country. We have demonstrated a major deviation from the current understanding of patterns of BMI increase, with a rate of increase substantially greater in the developing world context compared with the global pattern. This population-wide effect will have major consequences for national development as the epidemic of related non-communicable disease unfolds, and will overtax the national health care budget. Our refined understanding highlights that risks are further compounded for certain groups/places, and emphasizes that urgent geographical and population-targeted interventions are necessary. These interventions could include a sugar tax, clearer food labelling, revised school feeding programmes and mandatory bans on unhealthy food marketing to children.The scenario unfolding in South Africa will likely be followed in other LMICs. © The Author 2017.

    Full Text Available Along with the technology development and increasing consumption of water resources, we are experiencing low qualities in the mentioned resources. Copper brings about serious environment al pollution, threatening human health and ecosystem. This metal found variously in water resources and industrial activities. Therefore, it needs to treat the water resources from these excessive amounts. Different methods have used for this reason but the most used method during recent years has been the absorption by economic absorbers such as sand. Rapid sand filters usually used in water and wastewater treatment plants for water clarification. In this research, a single layer gravity rapid sand filter has used to reduce different concentrations of copper. sediment value and head loss arising in filter media is simulated by using combination of Carman-Kozeny, Rose and Gregory models in different discharges of rapid sand filter. Results have shown that with increasing in discharge and decreasing in input copper concentration, arriving time to given head loss, is increasing. In addition, results demonstrated that with increasing in copper concentration in influent, removal efficiency is decreasing somewhat. Results of this research can applied in an appropriate design of rapid sand filter to copper removal, a prediction of rapid sand filter ability to copper removal and an estimation of arising head loss during filter work thus evaluating of time interval backwash.

    Full Text Available Five years from the eruption of financial crisis in 2008, the global economy is also on its way to the restoration, among which the emerging economic entities, typically China, India, Brazil, South Africa, Indonesia, etc., have rapidly run away from the crisis and led the recovery of global economy, which may be considered as the engine of global economy growth in the post financial crisis. While, with the America declaring that it would gradually reduce the quantitative easing (QE scale and escaped from the quantitative easing policy in the mid 2014, the fluctuation of global financial market was rapidly intensified, and the risk assets were largely sold off, with the emerging economic entities suffering serious impact. Furthermore, the anxiety about the “third round of financial crisis will burst out due to the emerging economic entities” is increasingly intensified. This article will first analyze the current economic situation of main global economic entities, discuss about the impact of America’s escape from QE on the emerging economic entity and its mechanism, and finally propose the countermeasures for China.

    One approach in climate-change policy is to set normative long-term targets first and then infer the implied emissions pathways. An important example of a normative target is to limit the global-mean temperature change to a certain maximum. In general, reported cost estimates for limiting global warming often rise rapidly, even exponentially, as the scale of emission reductions from a reference level increases. This rapid rise may suggest that more ambitious policies may be prohibitively expensive. Here, we propose a probabilistic perspective, focused on the relationship between mitigation costs and the likelihood of achieving a climate target. We investigate the qualitative, functional relationship between the likelihood of achieving a normative target and the costs of climate-change mitigation. In contrast to the example of exponentially rising costs for lowering concentration levels, we show that the mitigation costs rise proportionally to the likelihood of meeting a temperature target, across a range of concentration levels. In economic terms investing in climate mitigation to increase the probability of achieving climate targets yields 'constant returns to scale', because of a counterbalancing rapid rise in the probabilities of meeting a temperature target as concentration is lowered.

    Full Text Available Renewable energy fueled power generations are few developed by private sector in Indonesia. High-cost investment and low electricity selling price to PT PLN as a single buyer is main barriers for private sector to involve in the development of renewable energy fueled power generations. In this project, the economic feasibility of Mini Hydro Power Plant of Cikaso with capacity of 5.3 MW, located at Sukabumi Regency, West Java province was assessed. This project utilized revenue generated from carbon market to increase the economic feasibility. Procedure to register the project to United Nation for Climate Change Convention (UNFCCC as a Clean Development Mechanism project was explained in detail. Approved Consolidation Methodology (ACM 0002 Version 12.3.0 was used to calculate grid emission factor in Jawa-Bali-Madura the grid electricity system. It was calculated that the grid emission factor is 0.833 (t-CO2/MWh, and the carbon emission reduction generated for this project is 21,982 ton/year. From the analysis result, it can be proven that the additional revenue from carbon credit could increase the project IRR from 10.28% to 13.52%.

    The increasing medical-technical progress as well as the dramatic demographic changes cause problems with regard to rapid enlargement of medical service offers, allocation of resources and a financing shortfall in the German public health system. The economization in the German Health System can also be perceived in ENT departments. After performing an internet search about the rapidly growing market for qualifications measures in health economics, we hence conducted an anonymous survey for ENT senior doctors and directors of the 34 German University Departments to evaluate their attitude towards, as well as their expectation of such an add-on qualification. Since the German government finalized the health care reform in the year 2000 such qualification measures rapidly developed: amongst others, 26 postgraduate, extra-occupational master programs have been inaugurated. The anonymous survey was answered by 105 ENT doctors (63 senior doctors, 27 vice professors and 15 directors). 63% out of these 105 colleagues considered such an add-on qualification to be mandatory. 41% of the colleagues were already "add-on qualified" in that field, only 10 of them by means of a study program. 71 of 105 colleagues (68%) considered the add-on qualification to be advantageous for their future personal career. With regard to the designated contents of the study program, "Staff Management" was even prioritized to "Hospital Financing" and "Cost Accounting". Aspects of management and a (health-) economical basic knowledge became an integral part of the daily routine for "first-line management doctors" also in (University) ENT-departments. © Georg Thieme Verlag KG Stuttgart · New York.

    1982-01-01

    The increasing uncertainty of oil supplies and the rapid price changes associated with this uncertainty have encouraged some nations to turn increasingly to nuclear energy to produce electricity. The economic penalty associated with no spent fuel reprocessing for the country of Spain is determined, and this serves as an example of one of the consequences of a nonproliferation policy of a ''throw-away'' fuel cycle. The growth rate of electricity is forecast, and the Spanish plan for the addition of nuclear plants is examined. The neutronics of the ''throw-away'', the uranium recycle, and the uranium and plutonium cycle systems are reviewed and the economics of each system compared. There is a definite economic advantage to the uranium and plutonium recycle system being employed as early as possible. Such employment will have favorable foreign trade imbalance implications and foster national independence of imported oil

    The energy consumption in Korea has greatly increased along with its rapid economic growth and industrialization since the 1970s. Total energy consumption increased at an average annual growth rate. Due to the lack of domestic energy resources, however, the overseas dependence rate of energy consumption has continuously increased. Also Climate change, resulting from increases in greenhouse gas emissions (GHG), is considered one of the biggest environmental dangers facing the world today. The objective and approach of this study are to compare the different types of scenarios in terms of the power plant type and CO{sub 2} emission from each power plant. We estimated cost of electricity generation using fuel cost, O and M cost(Operation and Maintenance Cost) and CO{sub 2} emission

    2017-01-01

    Full Text Available The economic integration between the United States and Mexico has affected the economic, political and social relations in the border region. The paper seeks to relate the increasing economic integration and business cycles of the economies of San Diego and Tijuana to the development of both national and binational economic organizations in the border region. The methodology of analysis uses both statistical estimations of the economic integration of San Diego and Tijuana and semi-structured interviews of economic organizations to analyze the increasing economic integration and the role and achievements of the cross-border economic organizations. The results showed that cross-border cooperation is predominately controlled by federal and state governments on both sides of the border. However, the main achievements of cross-border economic cooperation have been accomplished by local private organizations. The perspective of further local economic development greatly depends on both the possibility of increased involvement of federal governments and the growing encouragement of regional organizations.

    Vaccination programmes targeting disease elimination aim to achieve very high coverage levels (e.g. 95%). We calculated the precision of different clustered lot quality assurance sampling (LQAS) designs in computer-simulated surveys to provide local health officers in the field with preset LQAS plans to simply and rapidly assess programmes with high coverage targets. We calculated sample size (N), decision value (d) and misclassification errors (alpha and beta) of several LQAS plans by running 10 000 simulations. We kept the upper coverage threshold (UT) at 90% or 95% and decreased the lower threshold (LT) progressively by 5%. We measured the proportion of simulations with d unvaccinated individuals if the coverage was LT% (pLT) to calculate alpha (1-pLT). We divided N in clusters (between 5 and 10) and recalculated the errors hypothesising that the coverage would vary in the clusters according to a binomial distribution with preset standard deviations of 0.05 and 0.1 from the mean lot coverage. We selected the plans fulfilling these criteria: alpha LQAS plans dividing the lot in five clusters with N = 50 (5 x 10) and d = 4 to evaluate programmes with 95% coverage target and d = 7 to evaluate programmes with 90% target. These plans will considerably increase the feasibility and the rapidity of conducting the LQAS in the field.

  3. Estimating economic losses from earthquakes using an empirical approach

    2013-01-01

    We extended the U.S. Geological Survey's Prompt Assessment of Global Earthquakes for Response (PAGER) empirical fatality estimation methodology proposed by Jaiswal et al. (2009) to rapidly estimate economic losses after significant earthquakes worldwide. The requisite model inputs are shaking intensity estimates made by the ShakeMap system, the spatial distribution of population available from the LandScan database, modern and historic country or sub-country population and Gross Domestic Product (GDP) data, and economic loss data from Munich Re's historical earthquakes catalog. We developed a strategy to approximately scale GDP-based economic exposure for historical and recent earthquakes in order to estimate economic losses. The process consists of using a country-specific multiplicative factor to accommodate the disparity between economic exposure and the annual per capita GDP, and it has proven successful in hindcast-ing past losses. Although loss, population, shaking estimates, and economic data used in the calibration process are uncertain, approximate ranges of losses can be estimated for the primary purpose of gauging the overall scope of the disaster and coordinating response. The proposed methodology is both indirect and approximate and is thus best suited as a rapid loss estimation model for applications like the PAGER system.

    Rapid economic growth, industrialization, and urbanization in China have led to extremely severe air pollution that causes increasing negative effects on human health, visibility, and climate change. However, the influence mechanisms of these anthropogenic factors on fine particulate matter (PM 2.5 ) concentrations are poorly understood. In this study, we combined panel data and econometric methods to investigate the main anthropogenic factors that contribute to increasing PM 2.5 concentrations in China at the prefecture level from 1999 to 2011. The results showed that PM 2.5 concentrations and three anthropogenic factors were cointegrated. The panel Fully Modified Least Squares and panel Granger causality test results indicated that economic growth, industrialization, and urbanization increased PM 2.5 concentrations in the long run. The results implied that if China persists in its current development pattern, economic growth, industrialization and urbanization will inevitably lead to increased PM 2.5 emissions in the long term. Industrialization was the principal factor that affected PM 2.5 concentrations for the total panel, the industry-oriented panel and the service-oriented panel. PM 2.5 concentrations can be reduced at the cost of short-term economic growth and industrialization. However, reducing the urbanization level is not an efficient way to decrease PM 2.5 pollutions in the short term. The findings also suggest that a rapid reduction of PM 2.5 concentrations relying solely on adjusting these anthropogenic factors is difficult in a short-term for the heavily PM 2.5 -polluted panel. Moreover, the Chinese government will have to seek much broader policies that favor a decoupling of these coupling relationships.

    Ecosystems offer material and environmental support for human habitation and development in those areas of the earth where people choose to live. However, urbanization is an inexorable trend of human social development and threatens the health of those ecosystems inhabited by humans. This study calculates the values of NPP (net primary productivity), carbon sequestration, water interception, soil conservation, and agricultural production in the Guanzhong-Tianshui Economic Zone. At the same time, we combined DMSP/OLS (Defense Meteorological Satellite Program Operational Line Scanner) night lights remote sensing data and statistical data to analyze the level of urbanization. Quantitative analysis was performed on the interactions between the ecosystem service functions and urbanization based on the calculations of their coupled coordination degrees. The results were the following: (1) The values of NPP, carbon sequestration, and agricultural production showed a trend of increase. However, water interception decreased before increasing, while soil conservation showed the reverse trend; (2) Urbanization levels in the Guanzhong-Tianshui Economic Zone for the last 10 years have proceeded at a fast pace with comprehensive promotion; and (3) Coupled and coupled coordination degrees between urbanization and ecosystem services show increasing trends. This research can provide a theoretical basis for the region's rapid economic development in the balance.

  7. Clusters and the new economics of competition.

    Science.gov (United States)

    Porter, M E

    1998-01-01

    Economic geography in an era of global competition poses a paradox. In theory, location should no longer be a source of competitive advantage. Open global markets, rapid transportation, and high-speed communications should allow any company to source any thing from any place at any time. But in practice, Michael Porter demonstrates, location remains central to competition. Today's economic map of the world is characterized by what Porter calls clusters: critical masses in one place of linked industries and institutions--from suppliers to universities to government agencies--that enjoy unusual competitive success in a particular field. The most famous example are found in Silicon Valley and Hollywood, but clusters dot the world's landscape. Porter explains how clusters affect competition in three broad ways: first, by increasing the productivity of companies based in the area; second, by driving the direction and pace of innovation; and third, by stimulating the formation of new businesses within the cluster. Geographic, cultural, and institutional proximity provides companies with special access, closer relationships, better information, powerful incentives, and other advantages that are difficult to tap from a distance. The more complex, knowledge-based, and dynamic the world economy becomes, the more this is true. Competitive advantage lies increasingly in local things--knowledge, relationships, and motivation--that distant rivals cannot replicate. Porter challenges the conventional wisdom about how companies should be configured, how institutions such as universities can contribute to competitive success, and how governments can promote economic development and prosperity.

    Full Text Available The article is aimed at studying the organization of foreign economic activity of industrial enterprise in case of introduction of project approach to its management. New conditions of doing business in terms of aircraft building enterprises, consisting in the transition to production according to international standards, require a modern approach to the solution of the range of issues. In conditions of limited internal financial resources of company and high expenses connected with entering the foreign market, it is extremely important to define the priority directions of foreign economic activity and the most optimal mechanisms of its organization and management. The functioning of the sphere of foreign economic activity of industrial enterprise in case of introduction of project approach to management has been analyzed. The essence, features and the main parameters of project approach as a means of increasing the competitiveness of enterprise have been defined. Priorities of the large-scale enterprise development strategy have been analyzed and suggested by means of carrying out the project method of organization of foreign economic activity.

    Objective of this research project is to examine effects of addition of nuclear capacity from three different angles by using energy system, electricity market and economic analysis. In each area the analysis is based on computational methods. Finland is a member of Nordic electricity market which is further connected to networks of Continental Europe and Russia. Due to the foreign connections Finland has been able to import inexpensive electricity from its neighboring countries and this state is expected to continue. Addition of nuclear capacity lowers electricity import demand, affects level of electricity price decreasingly and decreases shortfall of installed production capacity. Substantial additions of nuclear power capacity and generous import supply have disadvantageous effect on profitability of combined heat and power production. The development of import possibilities depends on progression of difficult-to-estimate balance between electricity consumption and production in the neighboring countries. Investments on nuclear power increase national product during the construction phase. Growth of employment is also rather significant, especially during the construction phase. In the long term permanent jobs will be created too. Increase of employment is held back by increasing real wages, but it is though evident that consumer purchasing power is improved due to these nuclear power developments. (orig.)

  11. Blend-wall economics. Relaxing US ethanol regulations can lead to increased use of fossil fuels

    The US Environmental Protection Agency is currently considering a waiver allowing an increase in the fuel-ethanol blend limit (the 'blend wall') from 10% (E10) up to 15% (E15). Justifications for this waiver are reduced vehicle fuel prices and less consumption of petroleum gasoline leading to energy security. A theoretical examination of this waiver reveals an anomaly where a relaxation of this blend wall elicits a demand response. Under a wide range of elasticities, this demand response can actually increase the consumption of petroleum gasoline and thus lead to greater energy insecurity. The economics supporting this result and associated policy implications are developed and discussed. (author)

    Development of new treatments for drug addiction will depend on high-throughput screening in animal models. However, an addiction biomarker fit for rapid testing, and useful in both humans and animals, is not currently available. Economic models are promising candidates. They offer a structured quantitative approach to modeling behavior that is mathematically identical across species, and accruing evidence indicates economic-based descriptors of human behavior may be particularly useful biomarkers of addiction severity. However, economic demand has not yet been established as a biomarker of addiction-like behavior in animals, an essential final step in linking animal and human studies of addiction through economic models. We recently developed a mathematical approach for rapidly modeling economic demand in rats trained to self-administer cocaine. We show here that economic demand, as both a spontaneous trait and induced state, predicts addiction-like behavior, including relapse propensity, drug seeking in abstinence, and compulsive (punished) drug taking. These findings confirm economic demand as a biomarker of addiction-like behavior in rats. They also support the view that excessive motivation plays an important role in addiction while extending the idea that drug dependence represents a shift from initially recreational to compulsive drug use. Finally, we found that economic demand for cocaine predicted the efficacy of a promising pharmacotherapy (oxytocin) in attenuating cocaine-seeking behaviors across individuals, demonstrating that economic measures may be used to rapidly identify the clinical utility of prospective addiction treatments.

    The demand for healthcare services is increasing more rapidly than the supply of providers, while reimbursement levels ignore the free market law of supply and demand. The regulated healthcare environment in the United States fails to increase prices (i.e., reimbursement rates) as demand outstrips supply. Healthcare practitioners must find alternative methods in order to continue providing excellent patient care while at the same time maintaining an economically viable practice. Practice consolidation with the assistance of private equity healthcare investment is an extremely attractive solution to this imbalance.

    Malnutrition is locked in a vicious cycle of increased mortality, poor health, impaired cognitive development, slow physical growth, reduced learning capacity, inferior performance, and ultimately lower adult work performance and productivity. The consensus of global scientific evidence indicates that lowering the rates of malnutrition will be an indispensable component of any successful program to raise the quality of human capital and resources. This study used a "consequence model" to apply the coefficient risk-deficit on economic losses, established in the global scientific literature, to Cambodian health, demographic, and economic data to develop a national estimate of the value of economic losses due to malnutrition. The impact of the indicators of malnutrition analyzed represent a burden to the national economy of Cambodia estimated at 266 million USD annually (1.7% of GDP). Stunting is reducing the Cambodian economic output by more than 120 million USD, and iodine deficiency disorders alone by 57 million USD. This economic burden is too high in view of Cambodia's efforts to drive economic development. The government should rapidly expand a range of low-cost effective nutrition interventions to break the current cycle of increased mortality, poor health and ultimately lower work performance, productivity, and earnings.

    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.

    Full Text Available Stingless bees (kelulut keeping is now a trend in Malaysia. However, since demand for the source of colony in log is increasing, the log price is rapidly increasing. But, there is no data reported on the economic viability of meliponiculture in the current market price. Thus, the objective of this study is to clarify the economic viability of investment in meliponiculture in the current market price by engineering economic perspective. Investment in meliponiculture was analysed using Equivalent Annual Uniform Cost (EAUC, Internal Rate of Return (IRR and Breakeven Analysis. A small start-up with 30 units of logs or hives was considered in the analysis. All raw data was acquainted from current Malaysian market price, but only revenue from honey was considered. It was found that EAUC indicated that the annual worth of the log system is 23% better than the hive system. However, IRR calculation indicated that both the log and the hive systems offer margin exceeding 55% which is a very good return in general investment. In addition, it was also found that the log system had breakeven after 8th month, whereas the hive was 13th month. Better economic value could be obtained if revenue from by-products are considered. Thus, it can be concluded that meliponiculture is still very economically viable in Malaysia market trend, and the hive systems could be a better choice if splitting colony, maintenance, safety and aesthetics points of view are considered.

    Silver fir is one of the most productive and ecologically valuable native European tree species, however, it has been experiencing decline which has periodically occurred over its natural range. This paper aims to investigate the recent climate–growth relationships of silver fir (Abies alba Mill.) and its temporal change along the course of its life. Long-term tree-ring databases, as well as records on climate, atmospheric SO 2 , NO 3 and acid concentrations from four different regions in the Western Carpathians were used. The results provide clear evidence of significant increase of silver fir's radial increment over the entire Western Carpathian area since 1970–1980. The results indicated that the most probable factors behind the rapid recovery of tree radial increment were reductions in emissions of NO 3 and SO 2 , alongside a significant increase in mean June, July and April temperatures. Highlights: • Silver fir radial growth was mostly related to mean month late winter temperatures. • Silver fir growth also responded to summer, especially July temperatures. • Strength of the climate–growth response has gradually increased since 1960–1980. • SO 2 , NO 3 , and recent climate change as major factor of the rapid radial growth recovery. -- Reductions of SO 2 and NO 3 emission along with climate change are the major causes of the recent recovery of Silver fir radial growth

    The development of methods for rapid flood mapping and risk assessment is a key step to increase the usefulness of flood early warning systems and is crucial for effective emergency response and flood impact mitigation. Currently, flood early warning systems rarely include real-time components to assess potential impacts generated by forecasted flood events. To overcome this limitation, this study describes the benchmarking of an operational procedure for rapid flood risk assessment based on predictions issued by the European Flood Awareness System (EFAS). Daily streamflow forecasts produced for major European river networks are translated into event-based flood hazard maps using a large map catalogue derived from high-resolution hydrodynamic simulations. Flood hazard maps are then combined with exposure and vulnerability information, and the impacts of the forecasted flood events are evaluated in terms of flood-prone areas, economic damage and affected population, infrastructures and cities.An extensive testing of the operational procedure has been carried out by analysing the catastrophic floods of May 2014 in Bosnia-Herzegovina, Croatia and Serbia. The reliability of the flood mapping methodology is tested against satellite-based and report-based flood extent data, while modelled estimates of economic damage and affected population are compared against ground-based estimations. Finally, we evaluate the skill of risk estimates derived from EFAS flood forecasts with different lead times and combinations of probabilistic forecasts. Results highlight the potential of the real-time operational procedure in helping emergency response and management.

  1. The Reflection of Neoliberal Economic Policies on Education: Privatization of Education in Turkey

    Full Text Available This research reflects neoliberal economic policies by demonstrating the privatization of education in Turkey. The increase in the number of students of private schools and private schools in Turkey along with the relationship between public education investments and household income of education have been explained by using the document analysis technique from qualitative research methods. As in many countries, public education in Turkey has been removed from the basic human rights and commercialized and transformed into a commodity that has been bought and sold. Neoliberal transformation aims to generate a strong and dependent structure that eliminates political and economic freedoms. The documents published by the Ministry of National Education and the Turkish Statistical Institute were obtained from the relevant institutions and the data were analysed. It has been concluded that education has undergone a rapid privatization in Turkey, while investments in public education have decreased rapidly. Also the funds required to be allocated to public schools have been transferred to private schools, and the e

  2. Population increase, economic growth, educational inequality, and income distribution: some recent evidence.

    The relationship between population increase, economic growth, education and income inequality was examined in a cross-section study based on data from 26 developing and 2 developed countries. As other studies have noted, high population growth is associated with a less equal income distribution. A 1 percentage point reduction in the rate of population growth tends to raise the income share of the poorest 80% in the less developed world by almost 5 percentage points and is associated with a 1.7 percentage point increase in the income share of the poorest 40%. The relationship between short-run income growth and equality, on the other hand, is strong and positive. Estimates suggest that a 1 percentage point increase in the short-run rate of growth of the gross domestic product (GDP) increases the income share of the bottom 80% by about 2 percentage points and that of the poorest 40% by almost 1 percentage point. Although higher mean schooling appears to be a mild equalizer, educational inequality does not appear to have an adverse effect on income distribution. Overall, these results challenge the widely held belief that there must be a growth-equity trade-off. Moreover, they suggest that the impact of educational inequality on income distribution may be different from that observed in earlier studies, implying a need for caution in using these earlier results as a basis for educational policy development.

    The fast food (FF) industry has expanded rapidly in China during the past two decades, in parallel with an increase in the prevalence of obesity. Using government-reported longitudinal data from 21 provinces and cities in China, this study examined the growth over time and the spatial distribution patterns of the FF industry as well as the key social economic factors involved. We visualized the temporal and geographic distributions of FF industry development and conducted cross-sectional and longitudinal spatial analysis to assess associations between macroeconomic conditions, population dynamics, and the growth and distributional changes of the industry. It grew faster in the southeast coastal (more economically developed) areas since 2005 than in other regions. The industry was: 1) highly correlated with Gross Domestic Product; 2) highly correlated with per capita disposable income for urban residents; 3) moderately correlated with urban population; and 4) not correlated with an increase of population size. The mean center of the FF industry shifted westward as the mean center of the GDP moved in the same direction, while the mean center of the population shifted eastward. The results suggest that the rapid FF industry expansion in China was closely associated with economic growth and that improving the food environment should be a major component in local economic development planning.

    This study develops a methodology for rapidly obtaining approximate estimates of the economic consequences from numerous natural, man-made and technological threats. This software tool is intended for use by various decision makers and analysts to obtain estimates rapidly. It is programmed in Excel and Visual Basic for Applications (VBA) to facilitate its use. This tool is called E-CAT (Economic Consequence Analysis Tool) and accounts for the cumulative direct and indirect impacts (including resilience and behavioral factors that significantly affect base estimates) on the U.S. economy. E-CAT is intended to be a major step toward advancing the current state of economic consequence analysis (ECA) and also contributing to and developing interest in further research into complex but rapid turnaround approaches. The essence of the methodology involves running numerous simulations in a computable general equilibrium (CGE) model for each threat, yielding synthetic data for the estimation of a single regression equation based on the identification of key explanatory variables (threat characteristics and background conditions). This transforms the results of a complex model, which is beyond the reach of most users, into a "reduced form" model that is readily comprehensible. Functionality has been built into E-CAT so that its users can switch various consequence categories on and off in order to create customized profiles of economic consequences of numerous risk events. E-CAT incorporates uncertainty on both the input and output side in the course of the analysis.

    Full Text Available Background. Emerging research highlights the promise of community- and policy-level strategies in preventing youth violence. Large-scale economic developments, such as sports and entertainment arenas and casinos, may improve the living conditions, economics, public health, and overall wellbeing of area residents and may influence rates of violence within communities. Objective. To assess the effect of community economic development efforts on neighborhood residents’ perceptions on violence, safety, and economic benefits. Methods. Telephone survey in 2011 using a listed sample of randomly selected numbers in six Pittsburgh neighborhoods. Descriptive analyses examined measures of perceived violence and safety and economic benefit. Responses were compared across neighborhoods using chi-square tests for multiple comparisons. Survey results were compared to census and police data. Results. Residents in neighborhoods with the large-scale economic developments reported more casino-specific and arena-specific economic benefits. However, 42% of participants in the neighborhood with the entertainment arena felt there was an increase in crime, and 29% of respondents from the neighborhood with the casino felt there was an increase. In contrast, crime decreased in both neighborhoods. Conclusions. Large-scale economic developments have a direct influence on the perception of violence, despite actual violence rates.

    Land use change is a principal force and inherent element of global environmental change, threatening biodiversity, natural ecosystems, and their services. However, our ability to anticipate future land use change is severely limited by a lack of understanding of how major socio-economic disturbances (e.g., wars, revolutions, policy changes, and economic crises) affect land use. Here we explored to what extent socio-economic disturbances can shift land use systems onto a different trajectory, and whether this can result in less intensive land use. Our results show that the collapse of the Soviet Union in 1991 caused a major reorganization in land use systems. The effects of this socio-economic disturbance were at least as drastic as those of the nuclear disaster in the Chernobyl region in 1986. While the magnitudes of land abandonment were similar in Ukraine and Belarus in the case of the nuclear disaster (28% and 36% of previously farmed land, respectively), the rates of land abandonment after the collapse of the Soviet Union in Ukraine were twice as high as those in Belarus. This highlights that national policies and institutions play an important role in mediating effects of socio-economic disturbances. The socio-economic disturbance that we studied caused major hardship for local populations, yet also presents opportunities for conservation, as natural ecosystems are recovering on large areas of former farmland. Our results illustrate the potential of socio-economic disturbances to revert land use intensification and the important role institutions and policies play in determining land use systems' resilience against such socio-economic disturbances.

    Full Text Available The aim of this study was to assess changes in indirect markers of muscle damage and type I collagen degradation, as well as, patellar and Achilles tendon morphological differences during nine daily drop-jumps sessions with constant load alternated with rapid increases in load to test the hypothesis that frequent drop-jump training results in negative muscular and tendon adaptation. Young men (n = 9 performed daily drop jump workouts with progression every 3 days in terms of number of jumps, platform height and squat amplitude. Voluntary and electrically evoked knee extensor torque, muscle soreness, blood plasma creatine kinase (CK activity and carboxyterminal cross-linked telopeptide (ICTP, patellar and Achilles tendon thickness and cross-sectional area (CSA were assessed at different time points during the training period and again on days 1, 3, 10 and 17 after the training. The findings were as follows: (1 steady decline in maximal muscle strength with major recovery within 24 hours after the first six daily training sessions; (2 larger decline in electrically induced muscle torque and prolonged recovery during last three training sessions; (3 increase in patellar and Achilles tendons CSA without change in thickness towards the end of training period; (4 increase in jump height but not in muscle strength after whole training period. Our findings suggest that frequent drop-jump sessions with constant load alternated with rapid increases in load do not induce severe muscle damage or major changes in tendons, nonetheless, this type of loading is not advisable for muscle strength improvement.

    2015-05-01

    Full Text Available Health care systems around the globe are facing great challenges. The demand for health care is increasing due to the continuous development of new medical technologies, changing demographics, increasing income levels, and greater expectations from patients. The possibilities and willingness to expand health care resources, however, are limited. Consequently, health care organizations are increasingly required to take economic restrictions into account, and there is an urgent need for improved efficiency. It is reasonable to ask whether the health economics field of today is prepared and equipped to help us meet these challenges. Our aim with this article is twofold: to introduce the fields of behavioral and experimental economics and to then identify and characterize health economics areas where these two fields have a promising potential. We also discuss the advantages of a pluralistic view in health economics research, and we anticipate a dynamic future for health economics.

  14. Economic policy uncertainty index and economic activity: what causes what?

    2017-01-01

    Full Text Available This paper is a follow-up on the Economic Policy Uncertainty (EPU index, developed in 2011 by Baker, Bloom, and Davis. The principal idea of the EPU index is to quantify the level of uncertainty in an economic system, based on three separate pillars: news media, number of federal tax code provisions expiring in the following years, and disagreement amongst professional forecasters on future tendencies of relevant macroeconomic variables. Although the original EPU index was designed and published for the US economy, it had instantly caught the attention of numerous academics and was rapidly introduced in 15 countries worldwide. Extensive academic debate has been triggered on the importance of economic uncertainty relating to the intensity and persistence of the recent crisis. Despite the intensive (mostly politically-motivated debate, formal scientific confirmation of causality running from the EPU index to economic activity has not followed. Moreover, empirical literature has completely failed to conduct formal econometric testing of the Granger causality between the two mentioned phenomena. This paper provides an estimation of the Toda-Yamamoto causality test between the EPU index and economic activity in the USA and several European countries. The results do not provide a general conclusion: causality seems to run in both directions only for the USA, while only in one direction for France and Germany. Having taken into account the Great Recession of 2008, the main result does not change, therefore casting doubt on the index methodology and overall media bias.

    This paper analyses how governments in the EU(15) countries have succeeded in stimulating investments in wind turbines between 1985 and 2005. I use four different evaluation criteria (Tobin's Q, Euler equation estimation, investment accelerator model, and the effective marginal tax rate) to describe the observed investment patterns. After a period of rapid growth in capital stock (1985-2000), a period of modest growth (2001-2005) can be observed even though the economic attractiveness of investing increases modestly. This pattern cannot be explained by the evaluation criteria unless we accept economic attractiveness is a necessary condition and not a necessary and sufficient condition. When analysing which policy has worked best, the policies of Germany, Denmark and Spain stand out. Their early and consistent support has been based on feed-in tariffs combined with subsidies

  17. Economic development and family size.

    Rios, R J

    1991-01-01

    The demographic transition in Latin America has resulted in increased family size rather than the Western European model of reduced family size. In 1905, both fertility and mortality were high in Latin America, but mortality declined more rapidly in Latin America than in Europe. In 1905, the crude birth rate for 15 selected countries averaged 44/1000 population. Western fertility at a comparable transition point was much lower at 30/1000. Between 1905 and 1960, fertility declines were evident in Uruguay, Argentina, Cuba, and Chile. Between 1960 and 1985, fertility declines appeared in Costa Rica, Panama, Brazil, and Colombia. Fertility declines were smaller in the other Latin American countries. Crude birth rates declined markedly by 1985 but may overestimate fertility decline, which is more accurately measured by standardized birth rates. Fertility decline was evident in Argentina, Chile, and Costa Rica for standardized birth rates, survivorship ratio, and births surviving past the age of 15 years. Theoretically, families are expected to reduce family size when survivorship is assured; when mortality is 25%, only four children need be planned instead of six when mortality is 50%. A result of falling mortality is a cheaper cost of producing children, which may stimulate parents to raise bigger families. Western fertility decline has been attributed to mortality decline, urbanization, increased female labor force participation, rising wages, and more efficient contraception. Comparable economic development in Latin America has not resulted in large enough changes to encourage family size limitation. A table of fertility and economic indicators for selected countries in Latin America and Europe reflects the inverse relationship between income growth, urban growth, and growth in female educational status and fertility. The regression equation explains 60% of the variation in fertility rates among Latin American countries. Explanatory power increases to 75% when female

    2012-12-01

    Livestock production in sub-Saharan Africa (SSA) is not matching the annual 2.5 % growth of its population. Regional per capita meat and milk production corresponds, respectively, to about 13 and 8 % of developed countries indicators. Livestock performances in this region have decreased within the last 30 years. In fact, SSA, with a 12 % bovine extraction rate against a world average of 21 %, includes about 16 % of world cattle, only producing 6 and 2.6 % of global meat and milk, respectively. These low performances have economic and environmental consequences reflecting the necessity for upgrading livestock managing skills in the region. This effort includes various components such as sanitary prophylaxis, reproduction, nutrition, and in particular, substantial increase in livestock yield for human consumption. This will allow for an improved animal and pasture management and soil preservation, enhancing meat production and decreasing methane and nitrogen emissions from enteric fermentation and manure processing. These environmental gains due to increased livestock off-take rates can represent relevant credits in the global Environmental Carbon Market under the United Nations Framework Convention on Climate Change Kyoto protocol. These credits can be used for investments in livestock essential services and marketing facilities leading to improved productivity.

  20. BEHAVIORAL ECONOMICS AND THE NEED OF PSYCHOLOGY IN ECONOMIC RESEARCH

    2014-06-01

    Full Text Available The turning point in economic science has now come, marked especially by triggering the biggest crisis since the Great Depression of '29-'33, has called into question the need to reconsider the status of economic science and finding ways in which it can increase its practical foundations. In the elaboration of this study I’ve took into account the fact that beyond any abstract, formal and mathematical model, economics is a science, having the man in its center. Furthermore, every economic process is based on the human being. But the way individuals behave does not follow precisely the pattern predicted by classical and neoclassical models, but most of the time they are making decisions under the influence of psychological factors. Starting from these assumptions I considered important to highlight a real need for psychology in economic research. Therefore, the aim of this work is exclusively theoretical meant to show that the study of psychological factors is necessary in economic research, because it allows a better explanation of the economic problems and lead to obtaining results closer to reality than those who only take into consideration economic factors. In this way I appealed to behavioral economics. This represents a new trend of economic thinking that reunites psychology with economy. The thing that I observed after finishing the study is that behavioral economics can increase the explanatory power of economics by providing more realistic psychological bases, because human behavior is not only the subject matter of economics but psychology too.

  1. Water scarcity in the Arabian Peninsula and socio-economic implications

    2017-09-01

    The Arabian Gulf, one of the driest parts of the world, is already passing the water scarcity line as defined by the World Health Organization (WHO). The scarcity of renewable water resources and the growing discrepancy between demand and supply of water is a major challenge. Water scarcity is further worsened by rapidly growing demands due to rapid population growth, unsustainable consumption, climate change and weak management institutions and regulations. Water scarcity erodes the socio-economic sustainability of the communities that depend on the depleting storage. In this paper, an analysis of the water security situation within the Arabian Gulf region and the consequent socio-economic implications is presented.

    Full Text Available The present turning point, accentuated by the crisis, has revitalized the interdisciplinary study of economics and determined the reconsideration of its fundamental bases as a social science. The economists have abandoned the traditional neoclassical sphere and have directed towards understanding the behaviour resorting to psychology and developing in this manner a new field - behavioural economics. This article examines whether this economic sub-discipline is a viable research direction and the extent to which it may increase the explanatory power of science by providing a realistic database for analysis, taking into account the complexity of the human factor.

    As extinctions continue across the globe, conservation biologists are turning to species reintroduction programs as one optimistic tool for addressing the biodiversity crisis. For repatriation to become a viable strategy, fundamental prerequisites include determining the causes of declines and assessing whether the causes persist in the environment. Invasive species-especially pathogens-are an increasingly significant factor contributing to biodiversity loss. We hypothesized that Batrachochytrium dendrobatidis (Bd), the causative agent of the deadly amphibian disease chytridiomycosis, was important in the rapid (herpetological experts, analysis of archived field notes and museum specimen collections, and field sampling of the extant amphibian assemblage to examine (1) historical relative abundance of R. boylii ; (2) potential causes of R. boylii declines; and (3) historical and contemporary prevalence of Bd. We found that R. boylii were relatively abundant prior to their rapid extirpation, and an increase in Bd prevalence coincided with R. boylii declines during a time of rapid change in the region, wherein backcountry recreation, urban development, and the amphibian pet trade were all on the rise. In addition, extreme flooding during the winter of 1969 coincided with localized extirpations in R. boylii populations observed by interview respondents. We conclude that Bd likely played an important role in the rapid extirpation of R. boylii from southern California and that multiple natural and anthropogenic factors may have worked in concert to make this possible in a relatively short period of time. This study emphasizes the importance of recognizing historical ecological contexts in making future management and reintroduction decisions.

    Some experimental data suggest that rapid bolus administration of albumin causes less plasma-expanding effects than slow, continuous infusion. To determine whether rapid bolus administration, in comparison with slow infusion, results in greater extravasation of albumin in experimental septic shock we performed a randomized controlled trial with 32 endotoxemic pigs. The animals were monitored and ventilated with standard intensive care equipment and given 10 mL × kg 5% albumin labeled with Technetium-99m, either as a rapid 15-min bolus (Bolus group, n = 16) or as a 2-h infusion (Infusion group, n = 16). Radioactivity was monitored in plasma, extracellular microdialysate, and urine for 6 h. Physiological parameters were monitored hourly. Radioactivity in the liver, spleen, kidney, and lung was analyzed post mortem.The plasma area under the curve activity0-6 h was 4.4 ± 0.9 × 10 in the Bolus group and 4.4 ± 1.1 × 10 counts × min × mL × h in the Infusion group. Blood hemoglobin levels increased in both groups, suggesting severe capillary leakage. Yet, there were no group differences in albumin radioactivity in plasma, muscle tissue, urine, or in the post-mortem analysis of the organs. Following albumin administration, circulatory and respiratory parameters were similar in the two groups.In conclusion, the present results suggest that albumin might be given as a bolus without leading to increased extravasation of albumin, in contrast to previous animal experiments in rodents.

  5. Increasing efficiency in ethanol production: Water footprint and economic productivity of sugarcane ethanol under nine different water regimes in north-eastern Brazil

    Ethanol production in Brazil has grown by 219% between 2001 and 2012, increasing the use of land and water resources. In the semi-arid north-eastern Brazil, irrigation is the main way for improving sugarcane production. This study aimed at quantifying water consumed in ethanol production from sugarcane in this region using the water footprint (WF) indicator and complementing it with an evaluation of the water apparent productivity (WAP). This way we were able to provide a measure of the crop´s physical and economic water productivity using, respectively, the WF and WAP concepts. We studied sugarcane cultivation under nine different water regimes, including rainfed and full irrigation. Data from a mill of the state of Alagoas for three production seasons were used. Irrigation influenced sugarcane yield increasing total profit per hectare and economic water productivity. Full irrigation showed the lowest WF, 1229 litres of water per litre of ethanol (L/L), whereas rainfed production showed the highest WF, 1646 L/L. However, the lower WF in full irrigation as compared to the rest of the water regimes implied the use of higher volumes of blue water per cultivated hectare. Lower water regimes yielded the lowest economic productivity, 0.72 US$/m3 for rainfed production as compared to 1.11 US$/m3 for full irrigation. Since economic revenues are increased with higher water regimes, there are incentives for the development of these higher water regimes. This will lead to higher general crop water and economic productivity at field level, as green water is replaced by blue water consumption. (Author)

    Phasing out the use of nuclear energy for electricity production is often cited as a recommended policy strategy by anti-nuclear activists. This claim is very difficult to empirically test, however, Japan and Germany both offer interesting case studies into the economic, social, and greenhouse gas related consequences of phasing out nuclear energy on a rapid time scale. The results of the Japanese and German case studies inform a hypothetical phase out of nuclear energy from Ontario's energy mix. In all cases considered, rapid nuclear energy phase-out resulted in increased electricity costs, higher GHG emissions, and social externalities. (author)

    This analysis seeks to model and evaluate the economics of the use of Advanced Liquid Metal Reactors (ALMR) as a component of this country's future electricity generation mix. The ALMR concept has the ability to utilize as fuel the fissile material contained in previously irradiated nuclear fuel (i.e., spent fuel). While not a requirement for the successful deployment of ALMR power plant technology, the reprocessing of spent fuel from light water reactors (LWR) is necessary for any rapid introduction of ALMR power plants. In addition, the reprocessing of LWR spent fuel may reduce the number of high level waste repositories needed in the future by burning the long-lived actinides produced in the fission process. With this study, the relative economics of a number of potential scenarios related to these issues are evaluated. While not encompassing the full range of all possibilities, the cases reported here provide an indication of the potential costs, timings, and relative economic attractiveness of ALMR deployment

    Climate science suggests that, to have a high probability of limiting global warming to an average temperature increase of 2 °C, global greenhouse gas emissions must peak by 2020 and be reduced to close to zero by 2040. However, the current trend is heading towards at least 4 °C by 2100 and little effective action is being taken. This paper commences the process of developing contingency plans for a scenario in which a sudden major global climate impact galvanises governments to implement emergency climate mitigation targets and programs. Climate activists assert that rapid mitigation is feasible, invoking the scale and scope of wartime mobilisation strategies. This paper draws upon historical accounts of social, technological and economic restructurings in several countries during World War 2 in order to investigate potential applications of wartime experience to radical, rigorous and rapid climate mitigation strategies. We focus on the energy sector, the biggest single contributor to global climate change, in developed and rapidly developing countries. We find that, while wartime experience suggests some potential strategies for rapid climate mitigation in the areas of finance and labour, it also has severe limitations, resulting from its lack of democratic processes. - Highlights: • The paper explores the strengths and weaknesses of using wartime experience as a model for rapid climate mitigation. • Wartime experience suggests some potential strategies for rapid climate mitigation in the areas of finance and labour. • Wartime experience also has severe limitations, resulting from its lack of democratic processes

The crisis severely affected the labor market and employees’ well-being. Hence, the aim of this work is to implement a systematic review of the principal studies that analyze the impact of the economic crisis on the health of workers. We conducted our search on the PubMed database, and a total of 19 articles were selected for review. All studies showed that the economic crisis was an important stressor that had a negative impact on workers’ mental health. Most of the studies documented that a rise in unemployment, increased workload, staff reduction, and wages reduction were linked to an increased rate of mood disorders, anxiety, depression, dysthymia, and suicide. Some studies showed that problems related to the crisis may have also affected the general health of workers by increasing the risk of such health problems as cardiovascular and respiratory diseases. Finally, some studies looked at the impact of the crisis on health care services. These studies demonstrated that the reduction in public expenditure on health care services, and the reduction of public hospital budgets due to the recession, led to organizational problems (eg, medical supply shortages.Keywords: economic crisis, recession, work-related stress, mental health, risks assessment, occupational medicine

    Future success in microelectronics will demand rapid innovation, rapid product introduction and ability to react to a change in technological and business climate quickly. These technological advances in integrated electronics will require development of flexible manufacturing technology for VLSI systems. However, the current approach of establishing factories for mass manufacturing of chips at a cost of more than 200 million dollars is detrimental to flexible manufacturing. The authors propose concepts of a micro factory which may be characterized by more economical small scale production, higher flexibility to accommodate many products on several processes, and faster turnaround and learning. In-situ multiprocessing equipment where several process steps can be done in sequence may be a key ingredient in this approach. For this environment to be flexible, the equipment must have ability to change processing environment, requiring extensive in-situ measurements and real time control. This paper describes the development of a novel single wafer rapid thermal multiprocessing (RTM) reactor for next generation flexible VLSI manufacturing. This reactor will combine lamp heating, remote microwave plasma and photo processing in a single cold-wall chamber, with applications for multilayer in-situ growth and deposition of dielectrics, semiconductors and metals

    Over the past decades, many attempts have been made to assess the effects of integrated rice-duck farming on greenhouse gas emissions, use efficient of energy, soil fertility, and economic significance. However, very few studies have been focused on the effects of the farming on net ecosystem economic budget (NEEB). Here, a 2-year field experiment was conducted to comprehensively investigate the effects of ducks raised in paddy fields on CH 4 and N 2 O emissions, global warming potential (GWP), rice grain yield, and NEEB in central China. The experiment included two treatments: integrated rice-duck farming (RD) and conventional rice farming (R). The introduction of ducks into the paddy fields markedly increased the rice grain yield due to enhanced tiller number and root bleeding rate. RD treatment significantly elevated the N 2 O emissions (p < 0.05) but decreased CH 4 emissions (p < 0.05) during rice growing seasons compared with R treatment. Analysis of GWP based on CH 4 and N 2 O emissions showed that compared with R treatment, RD treatment significantly decreased the GWP by 28.1 and 28.0% and reduced the greenhouse gas intensity by 30.6 and 29.8% in 2009 and 2010, respectively. In addition, RD treatment increased NEEB by 40.8 and 39.7% respectively in 2009 and 2010 relative to R treatment. Taken together, our results suggest that the integrated rice-duck farming system is an effective strategy to optimize the economic and environmental benefits of paddy fields in central China.

    Malnutrition is locked in a vicious cycle of increased mortality, poor health, impaired cognitive development, slow physical growth, reduced learning capacity, inferior performance, and ultimately lower adult work performance and productivity. The consensus of global scientific evidence indicates that lowering the rates of malnutrition will be an indispensable component of any successful program to raise the quality of human capital and resources. This study used a “consequence model” to apply the coefficient risk-deficit on economic losses, established in the global scientific literature, to Cambodian health, demographic, and economic data to develop a national estimate of the value of economic losses due to malnutrition. The impact of the indicators of malnutrition analyzed represent a burden to the national economy of Cambodia estimated at 266 million USD annually (1.7% of GDP). Stunting is reducing the Cambodian economic output by more than 120 million USD, and iodine deficiency disorders alone by 57 million USD. This economic burden is too high in view of Cambodia’s efforts to drive economic development. The government should rapidly expand a range of low-cost effective nutrition interventions to break the current cycle of increased mortality, poor health and ultimately lower work performance, productivity, and earnings.

    With the rapid increase in the incidence and mortality of lung cancer, a growing number of lung cancer patients and their families are faced with a tremendous economic burden because of the high cost of treatment in China. This study was conducted to estimate the economic burden and patient responsibility of lung cancer patients and the impact of this burden on family income. This study uses data from a retrospective questionnaire survey conducted in 10 communities in urban China and includes 195 surviving lung cancer patients diagnosed over the previous five years. The calculation of direct economic burden included both direct medical and direct nonmedical costs. Indirect costs were calculated using the human capital approach, which measures the productivity lost for both patients and family caregivers. The price index was applied for the cost calculation. The average economic burden from lung cancer was $43,336 per patient, of which the direct cost per capita was $42,540 (98.16%) and the indirect cost per capita was $795 (1.84%). Of the total direct medical costs, 35.66% was paid by the insurer and 9.84% was not covered by insurance. The economic burden for diagnosed lung cancer patients in the first year following diagnosis was $30,277 per capita, which accounted for 171% of the household annual income, a percentage that fell to 107% after subtracting the compensation from medical insurance. The economic burden for lung cancer patients is substantial in the urban areas of China, and an effective control strategy to lower the cost is urgently needed.

    Reduction in smoking prevalence does not necessarily reduce the costs of smoking as evidence shows in developed countries. We provide up-to-date estimates for direct and indirect costs attributable to smoking in Hong Kong in 2011 and compare with our 1998 estimates. We took a societal perspective to include lives and life years lost, health care costs and time lost from work in the costing. We followed guidelines on estimating costs of active smoking for those aged 35 years or above (35+) and costs due to SHS exposure for 35+, infants aged 12 months and under and children aged 15 and below. All costs are in US$. We estimated that 6154 deaths among 35+ in Hong Kong in 2011 were attributable to active smoking, an increase of 10% from 1998. Besides, 672 deaths were attributable to SHS exposure, i.e. 10% of the total 6826 smoking-attributable deaths. The estimate of productive life lost due to deaths from active smoking by those aged under 65 years in 2011 was $166 million, an increase of about 4% over the estimate in 1998. Our conservative estimate of the annual tobacco-related disease cost in 2011 was $716 million which accounted for 0.3% of GDP. If we added the value of attributable lives lost, the annual cost would be $4.7 billion. Despite the reduction in smoking prevalence, smoking-attributable disease still imposes a substantial economic burden on Hong Kong society. These findings support more stringent and effective tobacco control legislation, polices and measures. Current evidence shows reduction in smoking prevalence does not necessarily reduce the economic costs of smoking. Most studies in developed countries employed a societal perspective, including costs of productivity loss and indirect costs, but not all studies estimated costs associated with second-hand smoking (SHS). The present study estimated the total costs of smoking in Hong Kong including direct and indirect costs attributable to active smoking and to SHS exposure. Our study confirms the

    Full Text Available Korea has developed rapidly since the 1960s. It is one of the four Asian tiger economies and a good model for developing countries. Korea shows the world how a developing country can develop its economy rapidly and become industrialized. Its development strategy has mainly been an export-oriented trade policy. As a result, its trade volume grew from $1 billion in 1966 to $1 trillion in 2011, which is a 1,000-fold increase within five decades. Since 2011, Korea has become one of seven countries with a trade volume over $1 trillion. However, the Korean economy has experienced turbulence as well as positive growth. It underwent severe economic crises such as the Asian financial crisis in 1997 and the global financial crisis in 2008. Its economy has been extremely vulnerable to the external economic environment, although it has improved and strengthened, particularly since the global financial crisis. During those two crises, the government carried out an appropriate trade policy with a strategic approach to upgrade its industrial structure and competitiveness in global markets. This article comprehensively discusses Korean trade policy and strategy over the last five decades, and how its national economy has developed rapidly. It also explores how the government sets its strategic targets in Asia and the Asia Pacific region. It considers two mega free trade agreements (FTAs — the Regional Comprehensive Economic Partnership and the Trans-Pacific Partnership — as new opportunities for further development. Therefore, it is wise to analyze these regional mega FTAs in order to maximize the national interest.

  4. The Economic Sovereignty of the State as the Defining Instrument of Economic Policy in the Context of Globalization

    Full Text Available The modern world is characterized by rapid integration and globalization processes, which have both a positive and a negative impact on the development of each country. National economies operate in the midst of global uncertainty, which is becoming the platform for the formation and implementation of the State economic policy, which should not only describe the conditions for strategic development of country but also adequately respond to the risks emerging out of the complex integration processes. The failure of the State to respond in a timely and adequate manner to the risks will result in lesser benefits and positive effects of integration processes than the impact of destabilizing factors. In such circumstances, economic sovereignty becomes the most important instrument of the State through which it can defend its national economic interests and form an effective economic policy.

    This paper presents the experimental investigation on the effects of the superfeed pressure together with economizer type on the performance of the twin-screw refrigeration compressor by means of the indicator diagram. With a pressure sensor embedded into the groove at the root of the female rotor on the discharge side, the pressure within the working chamber of a semi-hermetic twin-screw compressor with an economizer is recorded and then transformed into the indicator diagram. The results thus obtained are utilized to investigate the thermodynamic process of the compressor. It is shown that the compressor with an economizer has higher pressure during almost the whole compression process than without an economizer, resulting in the increase in the indicated power. Under different superfeed pressures, the pressure within the compression experiences different changes. This results in an optimal superfeed pressure for maximized compressor efficiency, which can be identified from the calculated compressor efficiency based on the indicator diagrams. It is also found that the pressure has a rapid increase at the beginning of superfeed process, and then a slow rise even a slight drop at the end of superfeed process, which is caused by the dynamic effect during superfeed process. Furthermore, if the superfeed pressure keeps the same, the pressure during compression in the compressor with the heat exchanger economizer is slightly higher than with the flash tank economizer, due to the higher temperature of superfeed refrigerant gas in the former case

    Experimental and theoretical flux models have been developed to reveal the influence of sun flecks and increasing CO2 concentrations on the energy and entropy balances of the leaf. The rapid and wide range of fluctuations in light intensity under field conditions were simulated in a climatic gas exchange chamber and we determined the energy and entropy balance of the leaf based on radiation and gas exchange measurements. It was estimated that the energy of photosynthetic active radiation (PAR) accounts for half of transpiration, which is the main factor responsible for the exportation of the entropy generated in photosynthesis (Sg) out of the leaf in order to maintain functional the photosynthetic machinery. Although the response of net photosynthetic production to increasing concentrations of CO2 under fluctuating light is similar to that under continuous light, rates of transpiration respond slowly to changes of light intensity and are barely affected by the concentration of CO2 in the range of 260-495 ppm, in which net photosynthesis increases by more than 100%. The analysis of the results confirms that future increases of CO2 will improve the efficiency of the conversion of radiant energy into biomass, but will not reduce the contribution of plant transpiration to the leaf thermal balance.

    The frequent outbreak of environmental threats in China has resulted in increased criticism regarding the health effects of China's urbanization. Urbanization is a double-edged sword with regard to health in China. Although great efforts have been made to investigate the mechanisms through which urbanization influences health, the effect of both economic development and urbanization on health in China is still unclear, and how urbanization-health (or development-health) relationships vary among different income groups remain poorly understood. To bridge these gaps, the present study investigates the impact of both urbanization and economic development on individuals' self-rated health and its underlying mechanisms in China. We use data from the national scale of the 2014 China Labor-force Dynamics Survey to analyze the impact of China's urbanization and economic development on health. A total of 14,791 individuals were sampled from 401 neighborhoods within 124 prefecture-level cities. Multilevel ordered logistic models were applied. Model results showed an inverted U-shaped relationship between individuals' self-rated health and urbanization rates (with a turning point of urbanization rate at 42.0%) and a positive linear relationship between their self-rated health and economic development. Model results also suggested that the urbanization-health relationship was inverted U-shaped for high- and middle-income people (with a turning point of urbanization rate at 0.0% and 49.2%, respectively), and the development-health relationship was inverted U-shaped for high- and low-income people (with turning points of GDP per capita at 93,462 yuan and 71,333 yuan, respectively) and linear for middle-income people. The impact of urbanization and economic development on health in China is complicated. Careful assessments are needed to understand the health impact of China's rapid urbanization.

    Objective: To provide high-quality, rapid and dependable result for clinical practice, and give satisfactory service to patients of different economical status by supplementation with other labeling immune examination. With an innovative attitude, we carried out efficient technical reform on ACS180 automatic chemiluminescence machine, making it possible for patients to complete the whole process including examination, check-out, diagnosis and getting drugs. The reported will be issued within an hour, thus a rapid immune detection service was established in out-patients department. Methods: 1. ACS-180 automatic chemiluminescence machine is used based on the principle of chemiluminescence immune methods. 2. The reagents are provided by Ciba-Comig Company of USA, composed of anti acridinium ester antibody of liquid phase and particulate antigen of solid phase wrapped in magnetic powder. 3. Calibration and quality control: high and low concentration are set for each calibration fluid with attached standard curve. Product for quality controlling includes three concentration of low, moderate and high. Results: 1. rapid machine detection for sample: serum is replaced with plasma coagulated by heparin, and comparison among series of methods using serum or plasma suggest no significant difference exists. 2. The problem about fasting detection: chemiluminescence machine measure optical density directly, with the results hardly being influenced by turbidity. But attention should be paid to the treatment of lipid turbid samples. 3. Other innovations: (1) direct placement of sample tube on machine: a cushion is placed on sample plate to transfer sample to machine directly after centrifugation, saving time and reducing the accident in sample transference. (2) for HCG quantification in blood and urine, 'gold criteria' is used firstly in screening to determine approximately the dilution range, with an advantage of saving time and reagent as well as accuracy.

    Traditionally, veal calves receive most of their nutrients from milk replacer (MR). Nowadays, however, solid feed (SF; i.e., concentrates and roughages) increasingly substitutes for MR. Studies have shown that providing SF reduces different types of nonnutritive oral behaviors. The objective of this study was to assess the economic and environmental effects of substituting SF for MR in veal calf diets. With respect to environmental effects, we considered the emission of greenhouse gases and land occupation. Substitution rates were based on an experiment in which 160 calves were provided 2 mixtures of SF at 4 levels of dry matter (DM) intake. Mixtures of SF contained either 80% concentrates, 10% corn silage, and 10% straw on DM basis (C80) or 50% concentrates, 25% corn silage, and 25% straw (C50). The 4 levels of SF during the last 17 wk of the fattening period were 20, 100, 180, and 260 kg of DM SF. Additionally, provision of MR was adjusted to achieve equal rates of carcass gain. Substitution rates, representing the SF equivalent needed to substitute for 1 kg of DM MR, were 1.43 kg of DM for C80 and 1.61 kg of DM for C50. Economic effects were assessed based on prices and substitution rates of SF for MR and the possible penalty for carcass color. Environmental effects were assessed based on effects related to the production of feed ingredients, substitution rates, and changes in enteric methane emission and energy use for feed preparation. Costs of feeding SF needed to substitute for 1 kg of DM MR were €0.68 lower for C80 and €0.71 lower for C50, compared with the costs of feeding 1 kg of DM MR. When carcass color scores became too high, however, lower feeding costs were offset by lower revenues from meat. Emissions of greenhouse gases were hardly affected when SF intake was increased. In general, increased enteric methane emission were offset by lower emissions from feed production and energy use. Land occupation increased when intake of SF was increased

    There has been a rapid expansion of radiation oncology services in developing countries over the past decade. The question arises of how far, how fast and which technology should be introduced and expanded and yet remain sustainable. The problem can be reduced to a simple issue of an increasing number of cancer cases (refer S. Whelan), hence increasing demand for radiotherapy in less-developed countries while the current resources for treatment are at present concentrated in well-developed countries. By 2015 there will be a shortfall of 10,000 teletherapy machines for providing radiotherapy. Micro- and macro-economic aspects that affect development of radiotherapy in developing countries are discussed

  12. Technology and economics of fermentation alcohol - an update

    1983-03-01

    Fermentation alcohol is being widely studied as an alternative fuel, and production is increasing, especially in Brazil, where the goal is more than 10 billion litres per year by 1985. Fuel markets are hundreds of times greater than the traditional ethanol markets which the existing industry supplies. To make a material contribution to fuel supply, fermentation ethanol must be treated as a major chemical and produced in large-volume, highly efficient plants. Such plants must be assured of a continuous supply of low-cost raw materials for which suitable processes have been developed and commercially proven. Sugar cane in the tropics and grains in some temperate countries meet these requirements; cellulosics do not qualify at present, nor will they in the foreseeable future, without major breakthroughs. Using techniques borrowed from the starch sweetener industry, starchy materials may be economically hydrolysed to fermentable sugars; rapid acid hydrolysis may prove superior to enzymatic processes. Major projects are under way to replace traditional batch or cascade fermentations with rapid, single-vessel continuous units, but these have not yet been fully proven. Where suitable, yeast recycle is being used as a means of increasing alcohol yields, and energy-efficient distillation methods of the petrochemical industry are being adopted. The consequent large reduction in steam consumption greatly reduces the appeal of other methods which have been proposed to remove water. Opportunities for process improvements abound, especially in developing (1) the means to provide cellulosic raw materials in large quantities at acceptable costs, (2) economically effective methods of pretreating and hydrolysing cellulosics, (3) practical organisms for converting five-carbon sugars to ethanol and (4) higher fermentation yields and efficiencies using bacteria or immobilized yeast.

    Full Text Available Ethanol production in Brazil has grown by 219% between 2001 and 2012, increasing the use of land and water resources. In the semi-arid north-eastern Brazil, irrigation is the main way for improving sugarcane production. This study aimed at quantifying water consumed in ethanol production from sugarcane in this region using the water footprint (WF indicator and complementing it with an evaluation of the water apparent productivity (WAP. This way we were able to provide a measure of the crop´s physical and economic water productivity using, respectively, the WF and WAP concepts. We studied sugarcane cultivation under nine different water regimes, including rainfed and full irrigation. Data from a mill of the state of Alagoas for three production seasons were used. Irrigation influenced sugarcane yield increasing total profit per hectare and economic water productivity. Full irrigation showed the lowest WF, 1229 litres of water per litre of ethanol (L/L, whereas rainfed production showed the highest WF, 1646 L/L. However, the lower WF in full irrigation as compared to the rest of the water regimes implied the use of higher volumes of blue water per cultivated hectare. Lower water regimes yielded the lowest economic productivity, 0.72 US$/m3 for rainfed production as compared to 1.11 US$/m3 for full irrigation. Since economic revenues are increased with higher water regimes, there are incentives for the development of these higher water regimes. This will lead to higher general crop water and economic productivity at field level, as green water is replaced by blue water consumption.

    Economic development is often evoked as a driving force that has the capacity to improve the social and health conditions of remote areas. However, development projects produce uneven impacts on local communities, according to their different positions within society. This study examines the spatial distribution of three major health threats in the Brazilian Amazon region that may undergo changes through highway construction. Homicide mortality, AIDS incidence and malaria prevalence rates were calculated for 70 municipalities located within the areas of influence of the Cuiabá-Santarém highway (BR-163), i.e. in the western part of the state of Pará state and the northern part of Mato Grosso. The municipalities were characterized using social and economic indicators such as gross domestic product (GDP), urban and indigenous populations, and recent migration. The municipalities' connections to the region's main transportation routes (BR-163 and Trans-Amazonian highways, along with the Amazon and Tapajós rivers) were identified by tagging the municipalities that have boundaries crossing these routes, using GIS overlay operations. Multiple regression was used to identify the major driving forces and constraints relating to the distribution of health threats. The main explanatory variables for higher malaria prevalence were: proximity to the Trans-Amazonian highway, high proportion of indigenous population and low proportion of migrants. High homicide rates were associated with high proportions of migrants, while connection to the Amazon River played a protective role. AIDS incidence was higher in municipalities with recent increases in GDP and high proportions of urban population. Highways induce social and environmental changes and play different roles in spreading and maintaining diseases and health threats. The most remote areas are still protected against violence but are vulnerable to malaria. Rapid economic and demographic growth increases the risk of AIDS

  17. Does increase in the depreciation expensing allowance spur economic growth? Evidence from USA

    2016-07-01

    Full Text Available Despite substantial evidence that economic growth is influenced by taxation, the impact of Section 179 on GDP is unclear. Section 179 of the Internal Revenue Code enacted in 1958 has operated for several decades in the United States. In addition, in late 2010, two congressional acts affecting Section 179 have been passed, i.e. The Tax Relief Act of 2010 and The Small Business Jobs Act of 2010. The essence of these adoptions is to provide incentives for corporate as well as individual taxpayers. However, there are concerns as to the degree of economic growth these adoptions will provide. This research is therefore focused on showing the correlation between these Section 179 deductions, depreciation and economic growth as the Section 179 figures are debated and changed annually. The study suggests that annual increments of capital depreciation deductions will aid corporate growth as well as other variables that affect economic growth in the United States. However, the benefits for small business are lower than for corporations.

  20. Ecological economics, energy, and sustainable development

    International Nuclear Information System (INIS)

    Peet, J.

    1991-01-01

    Conventional techniques of economics, in different countries, do not normally take proper account of increases in the cost of energy (especially oil) that are expected in the next twenty years, or the rapidly declining ability of the environment to absorb wastes and pollutants, especially those resulting from the use of fossil fuels. Unless these factors are included in political-economic decision-making, and paths for future development adjusted to take account of them, many future development options will be severely damaged. In this paper, it is argued that new decision-making principles are urgently needed, in which societies accept that the physics of the environment are dominant, and the desires of people are subject to physical constraints. When future development options are considered, there is therefore a hierarchy of decision-making. Primary decisions depend upon the physics and ecology of the environment, of development, and of resource utilization. These have to be made before secondary decisions which are mainly ethical, and depend upon social and community values. These are best expressed by people, through adult education and the political process. Only then is it possible to make tertiary decisions, which relate to the allocation of resources. These decisions will depend heavily upon the use of economic tools. Several approaches have been proposed for improving political-economic decision-making. Some concentrate on modifications to markets, so they can incorporate ''externalities''. In other approaches, physical understandings are introduced into policy analyses, in order to indicate the constraints that limit development options. Some important techniques are reviewed, and suggestions are made about better methods of decision-making in the future. (author)

    1999-02-01

    Economic crisis in Asia and its influences on Middle Eastern economy are explained based on statistics. In Asian countries domestic energy demand has increased rapidly with recent high rate of economic growth for a background. Crisis on currency and finance originated in Thailand in the second half of 1997 has spread to neighboring countries of Malaysia, Indonesia, Philippine and Republic of Korea, then economic depression and confusion has propagated all over Asia, and decrease in oil demands has caused sudden drop of oil price, which has an important effect upon economy of oil producing countries of Middle East. Drastic decrease in oil and gas income has resulted in downward modification of budget, cut down of expenditure and reexamination of investment projects, including suspension. Statistical data were shown on trades with Asian countries, effects of sudden drop in oil price in Iran and Saudi arabia and its deficit in finance. Recovery of Asian economy being slow, sharp increase in demand for oil and turn over of oil price can't be expected, and it seems that oil producing countries, who have economic structure of depending much on export of oil products such as crude oil, petroleum products and natural gas, will stay in distress for the time being.

  2. 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.

    Full Text Available Importance of industrialization which has a role in determination of the civilization levels of societies is increasing everyday due to meet rapidly increasing demands. However this process has led up to environmental problems with time and thus effects on quality of human life also brought along. In this study, three sectors were selected among different branches of industry according to their economical importance in Turkey. These sectors are paper, metal and construction chemicals industry. Production processes of selected sectors were examined and effects of production stages on the environment and human health as well as their contribution to sustainable development were investigated. Well known Turkish companies from each industrial branch were evaluated in detail. These industrial sectors having economic importance are compared to each other according to their effects on quality of human life and environment and the results are evaluated accordingly.

    2015-06-01

    Full Text Available World life expectancy is increasing and many populations will begin to age rapidly. The impeding prevalence of a greater number of older people living longer lives will have significant social and economic implications. It is important to understand how older people make economic and social decisions. Aging can be associated with a ‘phenomenon of decline’ and also greater wisdom. This paper seeks to examine the relationship between wisdom and aging. It reviews and connects the behavioral sciences and neuroscience literature on age differences in the following social and economic decision making domains that represent subcomponents of wisdom: 1 prosocial behavior in experimental economic games and competitive situations, 2 resolving social conflicts, 3 emotional homeostasis, 4 self-reflection, 5 dealing effectively with uncertainty in the domains of risk, ambiguity and intertemporal choice. Overall, we find a lack of research into how older people make economic and social decisions. There is, however, some evidence that older adults outperform young adults on certain subcomponents of wisdom, but the exact relationship between old age and each subcomponent remains unclear. A better understanding of these relationships holds the potential to alleviate a wide range of mental health problems, and has broad implications for social policies aimed at the elderly.

  7. The economics of offshore wind

    This paper presents an overview of the main issues associated with the economics of offshore wind. Investment in offshore wind systems has been growing rapidly throughout Europe, and the technology will be essential in meeting EU targets for renewable energy in 2020. Offshore wind suffers from high installation and connection costs, however, making government support essential. We review various support policies used in Europe, concluding that tender-based feed-in tariff schemes, as used in Denmark, may be best for providing adequate support while minimising developers' rents. It may prove economic to build an international offshore grid connecting wind farms belonging to different countries that are sited close to each other. (author)

    Full Text Available One of the determinants of the well-being of people across the world is economic freedom. It is the freedom to choose the ways to produce, sell, and use your private resources, while respecting rights of the other to practice the same. The primordial intention of the study was to investigate the factors affecting economic freedom in the Association of Southeast Asian Nations (ASEAN Economic Community. Human Development Index (HDI, Corruption Perceptions Index (CPI and GDP per capita are dimensions considered to characterize the level of a country’s economic freedom. Trend performance of AEC in these indexes was also determined. The empirical estimate was based on a panel dataset covering 6 member-countries of the ASEAN Economic Community from 2001 to 2010. The model was estimated through Ordinary Least Squares (OLS multiple linear regression analysis. For the trend performance of the indexes, Singapore found to have a remarkable performance. The empirical result strongly suggests that CPI and GDP per capita foster economic freedom. For every 1% decrease in CPI would lead to an increase in economic freedom index by.121 % and for every 1% increase in GDP per capita, EFI will increase by .019%.

    2017-01-01

    Full Text Available The development of theoretical provisions of economic security, their mechanisms and instruments is determined by the laws of the economy that reveal the management of production, the market processes of distribution, exchange, consumption, taking into account the features of industries, regions, the level of globalization, etc. Each sphere, region or branch of the economy is characterized by peculiar economic processes justified by a specific approach to their disclosure. Economic security, its emergence, development and adaptation to changing market conditions, is based on the information economy or on the knowledge economy. Economic security is determined by the costs of information, its confidentiality, taking into account the interaction, on the one hand, and the competition of various enterprises, regions and countries, on the other. In the process of economic development, knowledge in general and any specialists are needed, but only those that are necessary in the economy. Communication and interaction of science, knowledge, information with production provides not only economic security, but also their successful development. To develop certain principles or laws for the interaction of technological and economic factors, their degree and level of interaction, a study of economic activity was conducted. In the present study, a civilizational approach was used that is based on the determining role of man in the economy and society and the importance of knowledge and information, when the important mechanisms remain: the development of technology and technology, the role of knowledge and information, and communication. The implementation of the civilized approach takes into account the new methodological level of increasing economic security, when the main factor in the development of the economy is the scientific and technological progress that justifies the information path of economic development.

  11. Market design for rapid demand response

    Nielsen, Kurt; Tamirat, Tseganesh Wubale

    We suggest a market design for rapid demand response in electricity markets. The solution consists of remotely controlled switches, meters, forecasting models as well as a flexible auction market to set prices and select endusers job by job. The auction market motivates truth-telling and makes...... it simple to involve the endusers in advance and to activate demand response immediately. The collective solution is analyzed and economic simulations are conducted for the case of Kenya. Kenya has been su ering from unreliable electricity supply for many years and companies and households have learned...... to adjust by investments in backup generators. We focus on turning the many private backup generators into a demand response system. The economic simulation focuses on possible distortion introduced by various ways of splitting the generated surplus from the demand response system. An auction run instantly...

    Beck, R.J.

    1996-01-01

    The crucial oil-market issue for this year's second half is new supply. Production will increase again outside the Organization of Petroleum Exporting Countries. And Iraq has general approval to resume exports under limits set by the United Nations, although start of the exports has been delayed by at least 60 days. The big question is the market's ability to absorb the supply gains. As usual, the market's need for oil in the second half will depend on economies. So far in 1996, economic growth has pushed consumption to levels unexpected a year ago. Demand the rest of the year depends heavily on economic performances of the industrialized nations that make up the organization for Economic Cooperation and Development (OECD) and the rapidly growing nations of the Asia-Pacific region. Growth in countries elsewhere in the developing world, especially Latin America, remains a wild card. The paper discusses the worldwide outlook, crude oil prices, US product prices, natural gas prices, US economy, US energy demand, natural gas in the US, US oil demand, gasoline prices, distillate gains, resid slumps, LPG, ethane, US supply, production patterns, rise in refinery capacity, imports, stocks, and stock coverage

    2017-12-01

    Temperate "Mediterranean" climate regimes across the globe are particularly susceptible to wide swings between drought and flood—of which California's rapid transition from record multi-year dryness between 2012-2016 to extreme wetness during 2016-2017 provides a dramatic example. The wide-ranging human and environmental impacts of this recent "climate whiplash" event in a highly-populated, economically critical, and biodiverse region highlight the importance of understanding weather and climate extremes at both ends of the hydroclimatic spectrum. Previous studies have examined the potential contribution of anthropogenic warming to recent California extremes, but findings to date have been mixed and primarily drought-focused. Here, we use specific historical California flood and drought events as thresholds for quantifying long-term changes in precipitation extremes using a large ensemble of multi-decadal climate model simulations (CESM-LENS). We find that greenhouse gas emissions are already responsible for a detectable increase in both wet and dry extremes across portions of California, and that increasing 21st century "climate whiplash" will likely yield large increases in the frequency of both rapid "dry-to-wet" transitions and severe flood events over a wide range of timescales. This projected intensification of California's hydrological cycle would seriously challenge the region's existing water storage, conveyance, and flood control infrastructure—even absent large changes in mean precipitation.

    2016-03-01

    The present study investigates the relationship between economic growth and energy consumption by incorporating CO2 emissions, natural gas consumption and population in Malaysia. Annual data and F-bound test and granger causality have applied to test the existence of long run relationship between the series. The results show that variables are cointegrated for long run relationship. The results also indicate that natural gas consumption is an important contributing factor to energy demand and hence economic growth in case of Malaysia. The causality analysis highlights that the feedback hypothesis exists between economic growth and energy consumption. While, conservative hypothesis is validated between natural gas consumption and economic growth which implies that economic growth will push natural gas consumption policies in future. This study opens up new direction for policy makers to formulate a comprehensive natural gas policy to sustain environment for long span of time in case to achieve 11th MP targets.

  18. As good as it gets : Alberta economic profile and forecast

    Hirsch, T.

    2006-04-01

    This economic profile and forecast report for the province of Alberta revealed that nearly every sector of the economy is operating at full, or near full capacity. Alberta's strong economy is a result of high energy prices, rapid population growth and rising employment. Increased provincial government spending along with tax reductions for businesses also contribute to a strong economy. However, the the province still faces some economic challenges, including a general labour shortage. Forestry and agriculture are under pressure of low commodity prices and high input costs, and the province has not articulated a long-term strategy for managing non-renewable natural resource revenue. In addition, the provincial economy is highly dependent upon volatile energy prices. Despite these challenges, the report states that the momentum is on the side of continued economic growth in Alberta. The Canada West Foundation is forecasting real growth in the gross domestic product of 5.2 per cent for 2006 and 4.7 per cent for 2007. The strong energy sector is largely responsible for much of Alberta's economic growth. An estimated 20,000 wells will be drilled in the province in 2006, and high oil prices will lead to record drilling and oil sands investment. This report also highlighted the economic activity in other sectors, including manufacturing, tourism, international exports, hi-tech, forestry, agriculture, and construction. Information regarding interprovincial migration and population growth was included along with public finances. 16 figs

    1994-01-01

    The Advanced Liquid Metal Reactor (ALMR) has the potential to extend the economic life of the nuclear option and of reducing the number of high level waste repositories which will eventually be needed in an expanding nuclear economy. This paper reports on an analysis which models and evaluates the economics of the use of ALMRs as a component of this country's future electricity generation mix. The ALMR concept has the ability to utilize as fuel the fissile material contained in previously irradiated nuclear fuel (i.e., spent fuel) or from surplus weapons grade material. While not a requirement for the successful deployment of ALMR power plant technology, the reprocessing of spent fuel from light water reactors (LWR) is necessary for any rapid introduction of ALMR power plants. In addition, the reprocessing of LWR spent fuel may reduce the number of high level waste repositories needed in the future by burning the long-lived actinides produced in the fission process. With this study, the relative economics of a number of potential scenarios related to these issues are evaluated. While not encompassing the full range of all possibilities, the cases reported here provide an indication of the potential costs, timings, and relative economic attractiveness of ALMR deployment

    1993-01-01

    The Rapid Geophysical Surveyor (RGS) is a system designed to rapidly and economically collect closely-spaced geophysical data used for characterization of US Department of Energy waste sites. Geophysical surveys of waste sites are an important first step in the remediation and closure of these sites; especially older sites where historical records are inaccurate and survey benchmarks have changed because of refinements in coordinate controls and datum changes. Closely-spaced data are required to adequately differentiate pits, trenches, and soil vault rows whose edges may be only a few feet from each other. A prototype vehicle designed to collect magnetic field data was built at the Idaho National Engineering Laboratory (INEL) during the summer of 1992. The RGS was funded by the Buried Waste Integrated Demonstration program. This vehicle was demonstrated at the Subsurface Disposal Area (SDA) within the Radioactive Waste Management Complex at the INEL in September 1992. Magnetic data were collected over two areas in the SDA, with a total survey area of about 1.7 acres. Data were collected at a nominal density of 2 1/2 in. along survey lines spaced 1-ft apart. Over 350,000 data points were collected over a 6 day period corresponding to about 185 worker-days using conventional ground survey techniques

    2017-05-01

    Full Text Available The remarkable economic achievements of the past two centuries have cast an illusion of omniscience on the discipline of Economics, which even repeated catastrophic policy failures have still not entirely banished. The gap and disjuncture between prevailing economic wisdom and its effective application to promote human welfare and well-being are enormous and widening rapidly. The gap between current economic performance and the economic potential of global society has never been greater. Both have been aggravated by the rapid evolution of economy and society in recent decades. An ideology masquerading as scientific theory, mainstream theory fails to provide the necessary insights to guide us through the next phase of global social evolution. This paper summarizes major conclusions from a series of meetings organized by the World Academy of Art & Science over the past half-decade. It examines important premises and principles of a transdisciplinary framework for ecologically-sustainable, human-centered development founded on knowledge of the underlying social processes that govern human accomplishment and social evolution. It challenges the implicit values and assumptions on which current theory and practice are based. It exposes the central role played by social power in determining the operations of economy and the distribution of benefits in society. It seeks to construct a holistic paradigm to reunite and integrate thinking about economy with the political, legal, social, organizational, ecological and psychological dimensions of which economy has always been an inseparable part. It points to the need for a transnational theoretical framework as a unit of analysis and emphasizes a global perspective, which aims to maximize the well-being of humanity as a whole. In recent times, growing awareness of the limitations of the present economic system and the real planetary boundaries and ecological constraints on unlimited growth has overshadowed

    The growth rate of atmospheric carbon dioxide (CO2), the largest human contributor to human-induced climate change, is increasing rapidly. Three processes contribute to this rapid increase. Two of these processes concern emissions. Recent growth of the world economy combined with an increase in its carbon intensity have led to rapid growth in fossil fuel CO2 emissions since 2000: comparing the 1990s with 2000-2006, the emissions growth rate increased from 1.3% to 3.3%/y. The third process is indicated by increasing evidence (P 0.89) for a long-term (50-year) increase in the airborne fraction (AF) of CO2 emissions, implying a decline in the efficiency of CO2 sinks on land and oceans in absorbing anthropogenic emissions. Since 2000, the contributions of these three factors to the increase in the atmospheric CO2 growth rate have been ∼65 ± 16% from increasing global economic activity, 17 ± 6% from the increasing carbon intensity of the global economy, and 18 ± 15% from the increase in AF. An increasing AF is consistent with results of climate-carbon cycle models, but the magnitude of the observed signal appears larger than that estimated by models. All of these changes characterize a carbon cycle that is generating stronger-than-expected and sooner-than-expected climate forcing. airborne fraction anthropogenic carbon emissions carbon-climate feedback terrestrial and ocean carbon emissions vulnerabilities of the carbon cycle

  6. Explaining the Rapid Increase in Nigeria's Sex Ratio at Birth: Factors and Implications.

    This paper examines the rapid increase in Nigeria's sex ratio at birth from 1.03 boys born for every 1 girl born in each year from 1996-2008 to 1.06 in each year from 2009-2014, second only to Tunisia in Africa at 1.07. The average sex ratio at birth in the world in 2014 was 1.07. In most Black African nations or Black majority nations, it is 1.03 or less. Among the factors presented for this development are: historical fluctuations of sex ratio at birth; geography and ethnicity; male preference/chasing a son; Age of parents; high death rates of male infants and males in general; and wealth/socioeconomic status. Among the potential implications are: young and poor men in Nigeria may not be able to find brides and form families due to a potential shortage of females; emigration of young and poor Nigerian men to West (Africa) and elsewhere to seek brides and form families; immigration of marriage age women from West (Africa) and around the world to Nigeria to seek husbands; and low contraceptive use and high fertility rates in Nigeria.

    ENGLISH ABSTRACT: This article, presented in two parts, explains how to apply the Theory of Constraints (TOC in a business to increase Economic Value Added (EVA. The first part deals with the theory, while the second part deals with the implementation. The goal of a business, the measurements of the goal and the priority of the measurements are discussed. The future reality of a company which implements TOC principles is shown through cause and effect to lead to an increase in EVA. The increase in EVA is caused by an increase in return on investment and a reduction in the cost of capital. The actions the company must take to increase EVA is presented.

    During the last two decades in Korea, with the rapid economic growth and industrialization, nuclear power has played an important role in electric power production. At present, Korea has 11 nuclear units in operation with total installed capacity of 9,916MWe and 7 units under construction with total capacity of 6,100MWe. An advanced reactor development program, called Korean Next Generation Reactor (KNGR), has been started for the coming 21st century. It aims to enhance safety features compared to existing plants and follow the target to maintain the economic competitiveness of nuclear energy with alternative energy sources. In order to meet these requirements, a number of technical and economical factors have been taken into the program. These factors include the economy of plant size, design simplification and optimization, and reduction of construction period. This paper addresses the preliminary economic analysis results for the KNGR design. It is indicated that KNGR has about 17% economic advantage compared to the current 1,000 MWe PWR. This paper also describes some of the experiences gained and important factors related to reducing the investment and operation costs. 5 refs., 2 figs., 5 tabs

    Due to high population densities and rapid economic development, great number of cities worldwide rely heavily on external resources, and many are experiencing serious environmental pollution. Municipal governments are facing the issue of balancing the relationship between economic growth and environmental preservation. An urban system is an open, complex, dynamic ecological-economic system with different types of materials and resources. This paper combines emergy theory and System Dynamics (SD) and establishes an emergy-flow SD model of an urban eco-economic system that includes economic, population, waste and emergy sub-models. Three scenarios with different economic growth rates and investments in environmental preservation are designed to analyze the sustainable development capacity of Beijing under different scenarios. The results of the analysis show that current economic development in Beijing highly depends on resources consumption, especially the consumption of imported resources. Based on the current growth rate, development in Beijing will heavily depend on external resources that may make the system being more fragile in the future. A lower economic growth rate and a small increase in environmental preservation investment are more suitable for in Beijing than area higher economic growth rate and a large increase in environmental preservation investment. - Highlights: • A Systems Dynamics model simulating urban emergy flows is set up. • Current economic development of Beijing depends on high consumption of resources. • Beijing has extreme and increasing dependence on external resources. • Beijing relies heavily on nonrenewable resources and its development is unsustainable. • Low GDP growth is better than high GDP growth with increased environmental investment.

    The poor economic performance of the Philippines over the long term is a puzzle and an apparent anomaly for the region. The decline in the Philippines' global position from the first part of the 20th century is particularly striking when viewed against the backrdrop of rapid income gains in countries of East and Southeast Asia, countries the Philippines used to surpass in terms of physical and human capital. While there have been a number of attempts to explain the puzzle—difficult geography,...

    1994-01-01

    This paper discusses some of the consequences of deforestation in Algeria. It focuses on the Wilaya region of Jijel, in the eastern part of the country, which has some of the last, dense, sub-humid Mediterranean forests. The issue of a possible connection between the recent widespread deforestation and the drier conditions affecting the region is discussed. It is also shown how rapid social and economic changes have induced deforestation on such a large scale that erosion and soil losses are reaching unprecedented levels. The paper also points to the loss of economic potential for Algeria's forests. 38 refs, 2 figs, 3 tabs, 3 photos

    Infrastructures are needed for maintaining functionality and stability of society, while being put under substantial stresses from natural or man-made shocks. Since avoiding shock is impossible, increased focus is given to infrastructure resilience, which denotes the ability to recover and operate under new stable regimes. This paper addresses the problem of estimating, quantifying and planning for economic resilience of interdependent infrastructures, where interconnectedness adds to problem complexity. The risk-based economic input–output model enterprise, a useful tool for measuring the cascading effects of interdependent failures, is employed to introduce a framework for economic resilience estimation. We propose static and dynamic measures for resilience that confirm to well-known resilience concepts of robustness, rapidity, redundancy, and resourcefulness. The quantitative metrics proposed here (static resilience metric, time averaged level of operability, maximum loss of functionality, time to recovery) guide a preparedness decision making framework to promote interdependent economic resilience estimation. Using the metrics we introduce new multi-dimensional resilience functions that allow multiple resource allocation scenarios. Through an example problem we demonstrate the usefulness of these functions in guiding resource planning for building resilience

    2014-01-01

    A key part of any assessment of the global value of crop biotechnology in agriculture is an examination of its economic impact at the farm level. This paper follows earlier annual studies which examined economic impacts on yields, key costs of production, direct farm income and effects, and impacts on the production base of the four main crops of soybeans, corn, cotton and canola. The commercialization of genetically modified (GM) crops has continued to occur at a rapid rate, with important changes in both the overall level of adoption and impact occurring in 2012. This annual updated analysis shows that there have been very significant net economic benefits at the farm level amounting to $18.8 billion in 2012 and $116.6 billion for the 17-year period (in nominal terms). These economic gains have been divided roughly 50% each to farmers in developed and developing countries. GM technology have also made important contributions to increasing global production levels of the four main crops, having added 122 million tonnes and 230 million tonnes respectively, to the global production of soybeans and maize since the introduction of the technology in the mid-1990s.

    To describe the use of oral antidiabetic drugs for management of type 2 diabetes in the U.S. from 1990 through 2001. Data on oral antidiabetic drugs were derived from two pharmaceutical marketing databases from IMS Health, the National Prescription Audit Plus and the National Disease and Therapeutic Index. In 1990, 23.4 million outpatient prescriptions of oral antidiabetic agents were dispensed. By 2001, this number had increased 3.9-fold, to 91.8 million prescriptions. Glipizide and glyburide, two sulfonylurea medications, accounted for approximately 77% of prescriptions of oral antidiabetic drugs in 1990 and 35.5% of prescriptions in 2001. By 2001, the biguanide metformin (approved in 1995) had captured approximately 33% of prescriptions, and the thiazolidinedione insulin sensitizers (rosiglitazone and pioglitazone marketed beginning in 1999) accounted for approximately 17% of market share. Compared with patients treated in 1990, those in 2001 were proportionately younger and they more often used oral antidiabetic drugs and insulin in combination. Internists and general and family practitioners were the primary prescribers of this class of drugs. Consistent with the reported increase in the prevalence of type 2 diabetes, the number of dispensed outpatient prescriptions of oral antidiabetic drugs increased rapidly between 1990 and 2001. This period was marked by an increase in the treatment of younger people and the use of oral antidiabetic drugs in combination. With the approval in the last decade of several new types of oral antidiabetic medications with different mechanisms of action, options for management of type 2 diabetes have expanded.

  17. Economic evaluation of dual purpose desalination plants by fuel type in Korea

    2007-01-01

    In light of the recent rapid increase in the fossil fuel prices it is meaningful to evaluate the impact of these price changes in the economics of dual-purpose desalination projects producing electricity and fresh water simultaneously. The price of crude oil and LNG (Liquefied Natural Gas) has increased by about 200% and 100% during the past three or four years. The uranium price has also increased by nearly 500% during the same period. The purpose of this paper is to analyze and compare the economics of SMART (System-integrated Modular Advanced ReacTor) which is being developed as a small size PWR type and the LNG Combine Cycle coupled with MED (Multi-Effect Distillation) which are being acknowledged as promising energy sources for the future in Korea. The methods of analysis used in this paper are the lifetime leveled cost method for the power and water cost calculation and the power credit method for the total cost allocation. DEEP (Devaluation Economic Evaluation Program) developed by IAEA was used to perform an economic comparison between the two dual-purpose desalination projects. From the results of the analysis it is found that the desalination by SMART-MED is much superior to that of LNG CC-MED under the current economic and technical situations. It is also shown that the relative superiority of SMART-MED to LNG CC-MED will be maintained even in case where an increase in the uranium price and the SMART construction cost would reach a maximum in the sensitivity analysis. In the case that the discount rate declines to 5% per year, the relative attractiveness of SMART-MED which is a capital intensive plant will be enhanced when compared to that for a 7% discount rate. In addition to this, it is thought that a nuclear energy source will be favored much more than now in the field of desalination if the regulations for the emission of greenhouse gases are to be strengthened.

  19. Future fuel choices in Asia - the economics of gas

    International Nuclear Information System (INIS)

    Goldman, Daniel

    1993-01-01

    The greatest opportunities for foreign private sector involvement in gas-based power in Asia exist in the less developed countries. Factors contributing to these opportunities include rapid economic growth, increased environmental concern, the need for private sector finance and technology to sustain economic growth, an excess of under-developed gas reserves and continued advances in the efficiency of gas turbine combined cycle power generation. A tripling of gas demand is expected in Asia over the period 1992 to 2000 in meeting 100-120 GW of the new power capacity of 700 GW necessary to sustain planned economic growth. Supply costs are likely to be high, however. Despite the current excess of undeveloped reserves in Asia, these will not be sufficient to meet the demand, will be relatively expensive to develop and are often remote from the market centres. Greater dependence on liquefied natural gas from outside the region is inescapable. The economics of gas-fired production is also threatened by the prospective emergence of more efficient coal-based technologies. A fundamental change in gas contracting practices, recognizing the long term incremental avoided cost of power utilities, is needed in the face of high supply costs. The role of the private sector is crucial to the realisation of the fundamental environmental and technical advantages of gas-based power in Asia but there are difficulties to be overcome in the investment framework before a significant expansion in private projects can occur.

  20. Czech Republic: A rapid transformation of fertility and family behaviour after the collapse of state socialism

    Vladimíra Kantorová

    2008-07-01

    Full Text Available Following the swift demise of the state-socialist regime in 1989, a profound transformation of family and fertility patterns has taken place in the Czech Republic. Family formation has been postponed and period fertility rates have fallen to very low levels, especially among young adults. Unmarried cohabitation has become relatively widespread and marriages have been progressively delayed or even foregone. These rapid shifts in family-related behaviour were primarily driven by a period change and resulted in a sharp discontinuity in cohort patterns of union formation and childbearing. We argue that the rapid change in family-related behaviour after 1990 was driven by a fundamental shift in the constraints and incentives for childbearing, which was conducive to later and more carefully planned family formation. The rapidity of observed changes can be explained as the outcome of a simultaneous occurrence of several factors, especially the expansion of higher education, the emergence of new opportunities competing with family life, increasing job competition, rising economic uncertainty in young adulthood, and changing partnership behaviour.

  1. Nicotine reduction as an increase in the unit price of cigarettes: a behavioral economics approach.

    Science.gov (United States)

    Smith, Tracy T; Sved, Alan F; Hatsukami, Dorothy K; Donny, Eric C

    2014-11-01

    Urgent action is needed to reduce the harm caused by smoking. Product standards that reduce the addictiveness of cigarettes are now possible both in the U.S. and in countries party to the Framework Convention on Tobacco Control. Specifically, standards that required substantially reduced nicotine content in cigarettes could enable cessation in smokers and prevent future smoking among current non-smokers. Behavioral economics uses principles from the field of microeconomics to characterize how consumption of a reinforcer changes as a function of the unit price of that reinforcer (unit price=cost/reinforcer magnitude). A nicotine reduction policy might be considered an increase in the unit price of nicotine because smokers are paying more per unit of nicotine. This perspective allows principles from behavioral economics to be applied to nicotine reduction research questions, including how nicotine consumption, smoking behavior, use of other tobacco products, and use of other drugs of abuse are likely to be affected. This paper reviews the utility of this approach and evaluates the notion that a reduction in nicotine content is equivalent to a reduction in the reinforcement value of smoking-an assumption made by the unit price approach.

    Full Text Available Interactions of the national and the global in economic transformations occurring in open economic systems are substantiated. Conceptual approaches to the development of economic systems in the globalization and regionalization context are summed up. It is shown that globalization is a logical consequence of mutual influences and interactions of multiple local transformations in socio-economic systems of various levels, which planetary self-organization generates the new quality of the global economic development. It is concluded that globalization has controversial impact on the transformation capacities of national economic systems that have to operate in the unfavorable condition of the growing instability of the global economic system and rapid integration in the structures with already established economic relations. The heuristic and experimental nature of economic and institutional transformations in these countries is added by splits of national economic systems and disruptions of established production links; the outstripping liberalization of foreign economic relations, creating rather external than internal pressures on national manufacturers and making them less capable to adapt to the competitive environment; the accelerated liberalization of monetary and financial systems, opening up ways to reallocation of capital from the sluggish real sector to the more flexible sector of transactions with currencies and securities; the shrinking regulatory authorities of national governments with respect of trade, competition, tax policies or social welfare; the growing domination of TNC and outflow of productive resources from national economies, important for their self-development, thus making their economic systems structurally primitive; the sharp property differentiation within societies and the increasing shares of population with low incomes.

    Full Text Available This article considers the opportunities for Russia presented by the launch of China’s Silk Road Economic Belt initiative.This initiative is a comprehensive project for the rapid development of Central Asian countries, and not limited only to transportand logistics to guarantee the supply of Chinese goods to Europe. It is also China’s response to economic and political processes both within the country and in the Asia-Pacific region: the economic slow down and transformation of its social and economic model, diverging income levels, the growing presence of the United States in Asia, and the new divisions of labour within the region. The Silk Road initiative is based on China’s intention to create strong regional value chains, to outsource labour-intensive and environmentally harmful production, to foster the development of north west China including securing political stability in the Xinjiang Uighur Autonomous Region, and to guarantee the use of Chinese construction firms’ capacity. Goods transit is a secondary priority and justified not by commercial benefits from using land routes, but by the need to diversify export risks, arising due to the deteriorating military and political situation in the South China Sea. The 2015 Joint Statement on Cooperation on the Construction of Joint Eurasian Economic Union and the Silk Road Economic Belt projects resolves the issue of all egedly competitive goals of these complementary projects. The Eurasian Economic Union (EEU provides an institutional base for cooperation while the Silk Road initiative provide investments for their development. Russia may benefit from participating in the Silk Road initiative. First, it would help integrate its transportation system into the region’s logistics network and provide additional opportunities for transit and associated logistical services as well as access to growing regional markets. Second, the Silk Road initiative offers opportunities to strengthen

    Economic instruments for the implementation of environmental policies distinguish themselves from traditional tools (the 'command and control' type) for the reason that: they influence the costs and the benefits of the economic agents in question; they change the behaviour of the subjects in question in a way that they guarantee behaviour trends less harmful to the environment; they guarantee the assignment of adequate prices to the natural resources that traditionally don't have a price and therefore are consumed excessively by the economic subjects; normally they impose the transfer of economic resources to the disadvantage of the subjects responsible for the phenomena of pollution; certain objective pollution reduction data guarantee the minimization of the social costs of pollution abatement, that is, of the total costs on the economic system in general (economists define this characteristic as the 'static efficiency'); they guarantee what is called in economical jargon, the dynamic efficiency, i.e., in practice, they determine a continuous incentive for the reduction of the emission of the various pollutants and for the realization of the technological innovations that are able to control the pollution; they are more flexible than the instruments of direct regulation, because they leave the subjects a freedom of choice under different price conditions than in the past; they are flexible as well for the reason that the public operator can intervene rapidly to change the way of application

    2010-01-01

    In recent years, coal price has risen rapidly, which has also brought a sharp increase in the expenditures of thermal power plants in China. Meantime, the power production price and power retail price have not been adjusted accordingly and a large number of thermal power plants have incurred losses. The power industry is a key industry in the national economy. As such, a thorough analysis and evaluation of the economic influence of the electricity price should be conducted before electricity price adjustment is carried out. This paper analyses the influence of coal price adjustment on the electric power industry, and the influence of electricity price adjustment on the macroeconomy in China based on computable general equilibrium models. The conclusions are as follows: (1) a coal price increase causes a rise in the cost of the electric power industry, but the influence gradually descends with increase in coal price; and (2) an electricity price increase has an adverse influence on the total output, Gross Domestic Product (GDP), and the Consumer Price Index (CPI). Electricity price increases have a contractionary effect on economic development and, consequently, electricity price policy making must consequently consider all factors to minimize their adverse influence.

    A rapid immunodiagnostic test kit for rabies virus detection was evaluated using 51 clinical samples and 4 isolates of rabies virus. The quick detection of rabies virus under field conditions may be helpful in determining if post-exposure prophylaxis is needed, thereby avoiding unnecessary treatments, as well as undue economic burden. There are several widely used diagnostic methods for rabies, including fluorescent antibody tests, reverse transcription polymerase chain reaction, and electron microscopy; however, these methods include time-consuming, intricate, and costly procedures. The rapid immunodiagnostic test was able to detect rabies virus in clinical samples, including brain tissue and saliva, in addition to 10(3.2) 50% lethal dose (LD(50))/mL cell-adapted rabies virus. The assay was not cross-reactive with non-rabies virus microbes. When the performance of the rapid immunodiagnostic test was compared to a fluorescent antibody test, the rapid immunodiagnostic test had a sensitivity of 91.7% and specificity of 100% (95.8% CI).

    The paper deals with the direct application of Rapid Prototyping technologies for parts and spare parts production in production companies and the economic effect by making use of this technology. Traditional production technologies are technologies such as forging, cutting, machining, etc. These technologies are widely accepted and the teething troubles are solved. Rapid Prototyping technologies such as 3D printing on the other hand came into the focus in the recent years when the technologies and the produced quality gradually advanced. Providing flexibility and time efficiency the technology should also have a practical application in production. This paper has the aim to provide a case-study based on existing cost figures to show that these technologies are not limited to prototype developments.

    With the rapid economic development, the serious air pollution in Beijing attracts increasing attention in the last decade. Seen as one whole complex and grey system, the causal relationship between the social development and the air pollution in Beijing has been quantitatively analyzed in this paper. By using the grey relational model, the aim of this study is to explore how the socio-economic and human activities affect on the air pollution in the city of Beijing, China. Four air pollutants, as the particulate matter with size 2.5 micrometers or less (PM2.5), particulate matter with size 10 micrometers or less (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NOx), are selected as the indicators of air pollution. Additionally, fifteen socio-economic indicators are selected to account for the regional socio-economic characteristics (economy variables, energy consumption variables, pollution emissions variables, environment and construction activity variables). The results highlight that all variables are associated with the concentrations of the four selected air pollutants, but with notable differences between the air pollutants. Most of the socio-economic indicators, such as industrial output, total energy consumption are highly correlated with PM2.5, while PM10, SO2, and NOx present in general moderate correlations with most of the socio-economic variables. Contrary to other studies and reports this study reveals that vehicles and life energy do not have the strongest effect on air pollution in Beijing. This study provides useful information to reduce air pollution and support decision-making for sustainable development.

    Summary Sugammadex 16 mg kg−1 can be used for the immediate reversal of neuromuscular block 3 min after administration of rocuronium and could be used in place of succinylcholine for emergency intubation. We have systematically reviewed the efficacy and cost-effectiveness and made an economic assessment of sugammadex for immediate reversal. The economic assessment investigated whether sugammadex appears cost-effective under various assumptions about the value of any reduction in recovery time with sugammadex, the likelihood of a ‘can't intubate, can't ventilate’ (CICV) event, the age of the patient, and the length of the procedure. Three trials were included in the efficacy review. Sugammadex administered 3 or 5 min after rocuronium produced markedly faster recovery than placebo or spontaneous recovery from succinylcholine-induced block. No published economic evaluations were found. Our economic analyses showed that sugammadex appears more cost-effective, where the value of any reduction in recovery time is greater, where the reduction in mortality compared with succinylcholine is greater, and where the patient is younger, for lower probabilities of a CICV event and for long procedures which do not require profound block throughout. Because of the lack of evidence, the value of some parameters remains unknown, which makes it difficult to provide a definitive assessment of the cost-effectiveness of sugammadex in practice. The use of sugammadex in combination with high-dose rocuronium is efficacious. Further research is needed to clarify key parameters in the analysis and to allow a fuller economic assessment.

    2017-06-01

    Full Text Available Our paper is centered around the formation of theory of institutional modelling that includes principles and ideas reflecting the laws of societal development within the framework of institutional economic theory. We scrutinize and discuss the scientific principles of this institutional modelling that are increasingly postulated by the classics of institutional theory and find their way into the basics of the institutional economics. We propose scientific ideas concerning the new innovative approaches to institutional modelling. These ideas have been devised and developed on the basis of the results of our own original design, as well as on the formalisation and measurements of economic institutions, their functioning and evolution. Moreover, we consider the applied aspects of the institutional theory of modelling and employ them in our research for formalizing our results and maximising the practical outcome of our paper. Our results and findings might be useful for the researchers and stakeholders searching for the systematic and comprehensive description of institutional level modelling, the principles involved in this process and the main provisions of the institutional theory of economic modelling.

  15. Coniferous tree plantations in forest conditions-economic analysis of dedicated and semi-dedicated pathways to increase wood production

    To meet growing demand for wood, particularly softwoods, the authors study a number of new silvicultural pathways for planting 3 species: Douglas fir, spruce and maritime pine. The goal of these pathways is to achieve specialised production of either industrial and workable timber, or a mixture of industrial and workable timber with medium-diameter workable timber. Pathways of this type have already been standardised for hardwoods, generally on fertile farmland. In a less fertile forest context, softwoods have a significant potential for woody production but specialized pathways and their profitability have yet to be studied. This article describes the innovative work being done to construct and simulate profitable production, new potential pathways, where plantation density, rotation time, the level of fertility are made to vary using the data from the FCBA test network in conjunction with the FCBA growth models (Oasis for spruce and Douglas fir, Sylveco for maritime pine). Economic data is derived from auction sales statistics and the ONF management and forestry work costs for the period 2012-2015. The Economics module developed by FCBA and ONF on the Capsis platform in the framework of the ICI project (Futurol) was used for the economic simulations. The analyses show that compared to conventional pathways, these pathways generally increase productivity but are nonetheless less profitable than current economic assumptions, although results vary according to species, fertility and the particular pathway. The sensitivity study shows that variations in the price of wood could alter the performance ratings as between conventional and specialised pathways. (authors)

    Sagawa, N.

    1997-01-01

    Many people in the world express the concern that global warming will become an increasingly serious problem. A rapid increase in population and demand for energy in the Asian region must be discussed in this context. Despite the forecast of an increase in demand for energy, the Asian region is short of oil and natural gas resources. In addition, only less energy can be supplied by renewable energy sources in the Asian region than in the other regions because of high population density. Nuclear energy is an important energy resource for fulfilling the future increasing energy demand in the Asian region and for contributing to the suppression of carbon dioxide emissions. In the Asian region alone, however, we cannot rely limitlessly on LWR which does not use plutonium. According to a scenario analysis, the total capacity of nuclear power plants in the Asian region would reach large scale and the cumulative amount of demand for natural uranium will increase to about 5 million tons in the Asian region alone. Just the nuclear power plants of this scale in Asia alone will rapidly consume the world's cheap natural uranium resources if we rely only on natural uranium. In the Asian region, few countries have embarked on nuclear power generation and the capacity of equipment is still small. Currently, however, many plans for nuclear power generation are being designed. Many Asian countries obviously consider nuclear power generation as a valid option. Many potential policies must be examined in the light of future uncertainty. In the future, both renewable energy and nuclear energy must be resorted to. When nuclear energy is utilized, the use of plutonium and FBR in the Asian region must be taken into account in order to attain continual growth and development. (author)

    2010-12-01

    Full Text Available In the last century, the world has seen an acceleration of technological development in almost all the fields related to human life, leading to rapid improvement of living standards in most countries. Electricity industry is a basic economic branch, and is also a branch with high importance to the economy and social life of any country. This branch, which currently is the base of industrial, agricultural, transportation and telecommunications activities, and which characterizes the entire modern world civilization, began to develop only towards the late of the XXth century. Electricity is an energy form easily usable in production, household consumption, transport, telecommunications etc. It was the one that revolutionized manufacturing resources and equipment used in all fields. Electricity production worldwide has increased about 30 times since 1938. Coal maintained a vital role in the total energy sources, especially by ensuring price stability which is a major and indispensable factor for stability and further economic growth, and also by its distribution around the globe.

    2017-09-01

    Despite widespread belief in the benefits of economic growth, some scholars emphasize the potentially negative consequences of growth-and especially rapid growth-for social and political outcomes. Using data for 149 countries between 1960 and 2010, I analyze the effect of economic growth on fundamental human rights conditions. Dynamic random-effects and two-way fixed-effects estimators, both with and without instrumental variables, yield several conclusions. First, economic growth is causally prior to rights conditions. Second, economic growth has a modest positive effect on human rights, albeit with diminishing returns at high growth rates. Third, low-income countries account for much of this relationship: growth improves rights conditions for most low-income countries, but extremely rapid growth is inimical. Growth has little effect among middle-income countries, while for high-income countries the relationship is positive but not robust. I bring these findings to bear on long-standing debates between proponents and critics of modernization theory. Copyright © 2017 Elsevier Inc. All rights reserved.

    In this study, we attempt to quantify the benefits of various options of grid flexibility by measuring their impact on two measures: economic carrying capacity and system costs. Flexibility can increase ECC and reduce overall system costs. In some cases, options that provide a limited increase in ECC can provide significant operational savings, thus demonstrating the need to evaluate flexibility options using multiple metrics. The value of flexibility options varies regionally due to different generation mixes and types of renewables. The more rapid decline in PV value compared to wind makes PV more dependent on adding flexibility options, including transmission and energy storage.

    Full Text Available The problems of national and economic security maintenanceis aggravating in modern conditions of globalization and international competition related to controlof market channels, technological, information and natural resources.Today Russia is making all efforts to protect its position on the world stage and improve the lives of its citizens.Despite the worsening of the present economic, political and social differences in the world, the Russian Federation has its own national interests, which can be possible to fulfill only on the basis of sustainable development of the national economic security system.The latter traditionally determines the ability of the state economic system to maintain normal conditions for the national economy functioning and the population activity. The national economic securitystabilitycan be estimated only by the application of elaborate tools of the economic development indicators analysis and the threshold values examinationaimed at the determination of the quality characteristic of actual and the most successful model of the economic activity.The analysis of the current Russian economic situation showed the presence of some serious problems existing in the national economy. The economic security level of Russia, having a tendency to increase in the period of 1998-2013, has been sharply reduced to critical points since 2014. So, it is necessary to take some measures to restructure the system of economic security of the state. Based on the research it was identified the list of the most dangerous threats to the modern Russian economy, which includes: low level of the country industrial production; the economy dependence on goods import and raw materials export; low living standards of the population; the rapid growth of the shadow economy and corruption; the lack of civil science and innovationdevelopment.

    2007-01-01

    This study explores the inter-relationships among economy, energy and CO 2 emissions of 37 industrial sectors in Taiwan in order to provide insight regarding sustainable development policy making. Grey relation analysis was used to analyse the productivity, aggregate energy consumption, and the use of fuel mix (electricity, coal, oil and gas) in relation to CO 2 emission changes. An innovative evaluative index system was devised to explore grey relation grades among economics, energy and environmental quality. Results indicate that a rapid increase in electricity generation during the past 10 years is the main reason for CO 2 emission increase in Taiwan. The largest CO 2 emitting sectors include iron and steel, transportation, petrochemical materials, commerce and other services. Therefore, it is important to reduce the energy intensity of these sectors by energy conservation, efficiency improvement and adjustment of industrial structure towards high value-added products and services. Economic growth for all industries has a more significant influence, than does total energy consumption, on CO 2 emission increase in Taiwan. It is also important to decouple the energy consumption and production to reduce the impacts of CO 2 on economic growth. Furthermore, most of the sectors examined had increased CO 2 emissions, except for machinery and road transportation. For high energy intensive and CO 2 intensive industries, governmental policies for CO 2 mitigation should be directed towards low carbon fuels as well as towards enhancement of the demand side management mechanism, without loss of the nation's competitiveness

    Resolving the short phylogenetic branches that result from rapid evolutionary diversification often requires large numbers of loci. We collected targeted sequence capture data from 585 nuclear loci (541 ultraconserved elements and 44 protein-coding genes) to estimate the phylogenetic relationships among iguanian lizards in the North American genus Sceloporus. We tested for diversification rate shifts to determine if rapid radiation in the genus is correlated with chromosomal evolution. The phylogenomic trees that we obtained for Sceloporus using concatenation and coalescent-based species tree inference provide strong support for the monophyly and interrelationships among nearly all major groups. The diversification analysis supported one rate shift on the Sceloporus phylogeny approximately 20-25 million years ago that is associated with the doubling of the speciation rate from 0.06 species/million years (Ma) to 0.15 species/Ma. The posterior probability for this rate shift occurring on the branch leading to the Sceloporus species groups exhibiting increased chromosomal diversity is high (posterior probability = 0.997). Despite high levels of gene tree discordance, we were able to estimate a phylogenomic tree for Sceloporus that solves some of the taxonomic problems caused by previous analyses of fewer loci. The taxonomic changes that we propose using this new phylogenomic tree help clarify the number and composition of the major species groups in the genus. Our study provides new evidence for a putative link between chromosomal evolution and the rapid divergence and radiation of Sceloporus across North America.

    Full Text Available We examine the impact on student achievement of a face-to-face teacher workshop that also provides economics instructors with access to an electronic library of instructional and reference material for their economics classroom—Virtual Economics v. 3 (VE3, offered by the Council for Economic Education. Based on evidence using student and teacher-level administrative data from the Georgia Department of Education and controlling for students’ prior achievement in mathematics, we find evidence that the VE3 workshop experience increases student achievement in high school economics. Our difference-in-differences estimates suggest that teacher participation in the VE3 workshop increases student achievement by 0.061 standard deviations on Georgia’s high stakes economics end-of-course test. Future research should seek estimating the effect of treatments in education such as the VE3 workshop using randomized controlled trials (RCT.

    With one-fifth of the world's total population, China's prevention and control of cardiovascular disease (CVD) may affect the success of worldwide efforts to achieve sustainable CVD reduction. Understanding China's current cardiovascular epidemic requires awareness of the economic development in the past decades. The rapid economic transformations (industrialization, marketization, urbanization, globalization, and informationalization) contributed to the aging demography, unhealthy lifestyles, and environmental changes. The latter have predisposed to increasing cardiovascular risk factors and the CVD pandemic. Rising CVD rates have had a major economic impact, which has challenged the healthcare system and the whole society. With recognition of the importance of health, initial political steps and national actions have been taken to address the CVD epidemic. Looking to the future, we recommend that 4 priorities should be taken: pursue multisectorial government and nongovernment strategies targeting the underlying causes of CVD (the whole-of-government and whole-of-society policy); give priority to prevention; reform the healthcare system to fit the nature of noncommunicable diseases; and conduct research for evidence-based, low-cost, simple, sustainable, and scalable interventions. By pursuing the 4 priorities, the pandemic of CVD and other major noncommunicable diseases in China will be reversed and the global sustainable development goal achieved. © 2016 American Heart Association, Inc.

  5. Evaluation of the economic feasibility of radiation preservation of selected food commodities

    1977-01-01

    Food preservation methods have increased in importance with the rapid increase in world population. A novel preservation method, ionizing radiation, shows promising applications. Its economic feasibility has been carefully studied for the last two decades. The article reviews the literature on the economics of food irradiation. Cost-benefit analyses on irradiation of grain for disinfestation, on potatoes and onions for sprout inhibition and on mushrooms for retarding growth are surveyed in the first part. Calculations based on data of a few food-irradiation pilot plants and non-food irradiation plants indicate the cost range of the radiation treatment of these food items. The unit cost of irradiation would be only a few per cent of the value of produce treated and would not exceed the order of cost of other conventional preservation methods. The second part surveys the economic aspects of the application of ionizing radiation to food items including strawberries, certain tropical fruits, meat and marine products. The cost levels would seem to be acceptable to food processors. A food-irradiation plant would cost US$ 10 5 -10 6 and the annual operating cost would be from US$ 20000 to US$ 2 million. The prospective benefit of food irradiation would far outweigh the cost of treatment. Improved product quality, decreased spoilage losses and extension of shelf-life are considered to constitute the main benefits of food irradiation. (author)

    2017-07-01

    A simple, rapid and economical mini-column method for detecting malachite green (MG) residue in fish was developed. The method used a column with 2mm ID that was tightly packed with silica gel followed by alumina. Detection of MG was performed by viewing the developed mini-column at visible light by naked eye; where MG was seen as compact green band at the confluence of the silica gel layer with alumina layer. The limit of detection of the assay was 2ng which conform the minimum required performance limit (MRPL). Evaluation utility of the method indicated that all blank and spiked samples at levels below MRPL were assessed as accepted. The intensity of the green band increased whenever MG level in the extract increased; indicated that suggested mini-column technique could be used for semi-quantitative determination of MG in fish samples. The method can be used to select the questionable samples. Copyright © 2017 Elsevier Ltd. All rights reserved.

  8. The Effect of Government Debt and Other Determinants on Economic Growth: The Greek Experience

    Panagiotis Pegkas

    2018-02-01

    Full Text Available This study empirically investigates the relationship between economic growth and several factors (investment, private and government consumption, trade openness, population growth and government debt in Greece, where imbalances persist several years after the financial crisis. The results reveal a long-run relationship between variables. Investment as private and government consumption and trade openness affect positively growth. On the other hand, there is a negative long-run effect of government debt and population growth on growth. Furthermore, the study addresses the issue of break effects between government debt and economic growth. The results indicate that the relationship between debt and growth depends on the debt breaks. Specifically, at debt levels before 2000, increases in the government debt-to-GDP ratio are associated with insignificant effects on economic growth. However, as government debt rises after 2000, the effect on economic growth diminishes rapidly and the growth impacts become negative. The challenge for policy makers in Greece is to halt the rising of government debt by keeping a sustainable growth path. Fiscal discipline should be combined with the implementation of coherent, consistent and sequential growth-enhancing structural reforms.

  9. Economic feasibility of radioactive scrap steel recycling

    1995-01-01

    In the past, government and commercial nuclear operators treated radioactive scrap steel (RSS) as a liability and disposed of it by burial; this was an accepted and economical solution at that time. Today, environmental concerns about burial are changing the waste disposal picture by (a) causing burial costs to soar rapidly, (b) creating pressure to close existing burial sites, and (c) making it difficult and expensive to open and operate burial facilities. To exacerbate the problem, planned dismantling of nuclear facilities will substantially increase volumes of RSS open-quotes wasteclose quotes over the next 30 yr. This report describes a project with the intention of integrating the current commercial mini-mill approach of recycling uncontaminated steel with radiological controls to design a system that can process contaminated metals at prices significantly below the current processors or burial costs

  10. High Early-Age Strength Concrete for Rapid Repair

    Maler, Matthew O.

    The aim of this research was to identify High Early-Age Strength (HES) concrete batch designs, and evaluate their suitability for use in the rapid repair of highways and bridge decks. To this end, two criteria needed to be met; a minimum compressive strength of 20.68 MPa (3000 psi) in no later than 12 hours, and a drying shrinkage of less than 0.06 % at 28 days after curing. The evaluations included both air-entrained, and non-air-entrained concretes. The cement types chosen for this study included Type III and Type V Portland cement and "Rapid Set"--a Calcium Sulfoaluminate (CSA) cement. In addition, two blended concretes containing different ratios of Type V Portland cement and CSA cement were investigated. The evaluation of the studied concretes included mechanical properties and transport properties. Additionally, dimensional stability and durability were investigated. Evaluations were conducted based on cement type and common cement factor. Fresh property tests showed that in order to provide a comparable workability, and still remain within manufactures guideline for plasticizer, the water-to-cement ratio was adjusted for each type of cement utilized. This resulted in the need to increase the water-to-cement ratio as the Blaine Fineness of the cement type increased (0.275 for Type V Portland cement, 0.35 for Type III Portland cement, and 0.4 for Rapid Set cement). It was also observed that negligible changes in setting time occurred with increasing cement content, whereas changes in cement type produced notable differences. The addition of air-entrainment had beneficial effect on workability for the lower cement factors. Increasing trends for peak hydration heat were seen with increases in cement factor, cement Blaine Fineness, and accelerator dosage. Evaluation of hardened properties revealed opening times as low as 5 hours for Type V Portland cement with 2.0 % accelerator per cement weight and further reduction in opening time by an hour when accelerator

    To demonstrate drug/polymer nanoparticles can increase the rate and extent of oral absorption of a low-solubility, high-permeability drug. Amorphous drug/polymer nanoparticles containing celecoxib were prepared using ethyl cellulose and either sodium caseinate or bile salt. Nanoparticles were characterized using dynamic light scattering, transmission and scanning electron microscopy, and differential scanning calorimetry. Drug release and resuspension studies were performed using high-performance liquid chromatography. Pharmacokinetic studies were performed in dogs and humans. A physical model is presented describing the nanoparticle state of matter and release performance. Nanoparticles dosed orally in aqueous suspensions provided higher systemic exposure and faster attainment of peak plasma concentrations than commercial capsules, with median time to maximum drug concentration (Tmax) of 0.75 h in humans for nanoparticles vs. 3 h for commercial capsules. Nanoparticles released celecoxib rapidly and provided higher dissolved-drug concentrations than micronized crystalline drug. Nanoparticle suspensions are stable for several days and can be spray-dried to form dry powders that resuspend in water. Drug/polymer nanoparticles are well suited for providing rapid oral absorption and increased bioavailability of BCS Class II drugs.

  13. Lending sociodynamics and economic instability

    Hawkins, Raymond J.

    2011-11-01

    We show how the dynamics of economic instability and financial crises articulated by Keynes in the General Theory and developed by Minsky as the Financial Instability Hypothesis can be formalized using Weidlich’s sociodynamics of opinion formation. The model addresses both the lending sentiment of a lender in isolation as well as the impact on that lending sentiment of the behavior of other lenders. The risk associated with lending is incorporated through a stochastic treatment of loan dynamics that treats prepayment and default as competing risks. With this model we are able to generate endogenously the rapid changes in lending opinion that attend slow changes in lending profitability and find these dynamics to be consistent with the rise and collapse of the non-Agency mortgage-backed securities market in 2007/2008. As the parameters of this model correspond to well-known phenomena in cognitive and social psychology, we can both explain why economic instability has proved robust to advances in risk measurement and suggest how policy for reducing economic instability might be formulated in an experimentally sound manner.

Breastfeeding is known to improve health outcomes in adulthood, is associated with reduced risk of developing chronic disease, and is therefore an important public health issue for this rapidly increasing population. Factors associated with infant feeding practices were examined in a cohort of 125 Emirati women and their infants, with data collected at birth and 3, 6 and 15 months postpartum by questionnaires and interviews. Participants were recruited in the Corniche Hospital, the main maternity hospital in the city of Abu Dhabi. Factors affecting the duration of breastfeeding and the introduction of complementary foods were investigated using univariate and multivariate statistics. Recommended infant feeding practices, such as exclusive breastfeeding for the first six months of life and timely introduction of appropriate complementary foods, were poorly adhered to. Factors implicated in early cessation of breastfeeding included: time to first breastfeed, mother’s education level, employment status and early introduction of complementary foods.

    Prentice, Andrew M

    2018-01-01

    Undernutrition in both its acute and chronic forms (wasting and stunting) is strongly inversely correlated with the wealth of nations. Consequently, as many low- and middle-income countries (LMICs) achieve economic advancement and pass through the so-called "nutrition transition," their rates of undernutrition decline. Many countries successfully achieved the Millennium Development Goal of halving undernutrition and whole continents have been transformed in recent decades. The exception is Africa where the slower rates of decline in the prevalence of undernutrition has been overtaken by population growth so that the absolute number of stunted children is rising. In many regions, economic transition is causing a rapid increase in the number of overweight and obese people. The rapidity of this rise is such that many nations bear the simultaneous burdens of under- and overnutrition; termed the "double burden" of malnutrition. This double burden, accompanied as it is by the unfinished agenda of high levels of infectious diseases, is crippling the health systems of many LMICs and thus requires urgent attention. Although the prognosis looks threatening for many poor countries, they have the advantage of being able to learn from the mistakes made by other nations that have passed through the transition before them. Concerted action across many arms of government would achieve huge future dividends in health and wealth for any nations that can grasp the challenge. © 2018 S. Karger AG, Basel.

  18. Energy consumption and economic growth in Turkey during the past two decades

    The Turkish economy has undergone a transformation from agricultural to industrial, enhanced by rapid urbanization, especially after 1982. Turkey's gross national production has grown at an average annual rate of 5% since 1983, ranking it at the top of the OECD countries, although the growth pattern has been uneven. Economic growth in recent years has been associated with the privatization of public enterprises. Turkey's energy demand has risen rapidly as a result of social and economic development. The country's energy consumption has grown considerably since the beginning of the 1980s. The Turkish government encourages foreign and Turkish private sector investors to implement the energy projects and is currently working on a new investment model for the construction of new generation plants to create the additional capacity needed. The Turkish energy sector, with its current size of 30 billion US dollars and projected size of 55 billion US dollars by 2015, as well as the fundamental restructuring process it has been going through since 2001, attracts both local and foreign investors. The sector needs an investment amount of approximately 130 billion US dollars by 2020. The aim of the present paper is to investigate the increasing of Turkish energy demand with the growth of the economy and utilization of domestic energy sources and the case of investments and imports in Turkey during the past two decades

  19. Social murder: the long-term effects of conservative economic policy.

    Chernomas, Robert; Hudson, Ian

    2009-01-01

    In this article, the authors take inspiration from Engels's 1845 account of the social murder committed by British capitalists to assess the contemporary impact of conservative economic policy, which they define as policies designed to maximize the accumulation of profit while socializing the associated risks and costs. Conservative economists argue that if their policy prescription is followed, it will produce broad-based economic benefits including more rapid growth, higher incomes, less illness, and, even, more democracy. The authors contrast the myth of conservative economic policy with the reality. What conservative economic policy has actually accomplished is a redistribution of wealth and power away from the vast majority of the population to firms and their owners. The effects of these policies on citizens and workers have been socially determined economic instability, unemployment, poverty, inequality, dangerous products, and infectious and chronic disease.

    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.

    Goldberg, Gertrude Schaffner

    2012-07-01

    To social workers, extreme economic inequality is primarily a violation of social justice, but this article shows how growing economic inequality since the mid-1970s was not only unjust, but also dysfunctional to the U.S. economy and linked to the recent economic crisis with its devastating effects, particularly on the social work clientele. The article identifies interrelated changes in ideology, the market economy, and government policies since the mid-1970s; contrasts the political economy of this period with the preceding post-World War II decades when the trend was toward a "shared prosperity"; and shows how increased economic inequality and political consequences that undermined democracy itself contributed to the economic meltdown. The analysis has implications for the direction of social reform and for broadening the constituency of social movements in pursuit of the social work mission of social justice. How social workers can contribute to such movements and to a reduction of economic and political inequality is explored.

    2014-05-01

    The demand for economic models that evaluate cancer treatments is increasing, as healthcare decision makers struggle for ways to manage their budgets while providing the best care possible to patients with cancer. Yet, after nearly 2 decades of cultivating and refining techniques for modeling the cost-effectiveness and budget impact of cancer therapies, serious methodologic and policy challenges have emerged that question the adequacy of economic modeling as a sound decision-making tool in oncology. We sought to explore some of the contentious issues associated with the development and use of oncology economic models as informative tools in current healthcare decision-making. Our objective was to draw attention to these complex pharmacoeconomic concerns and to promote discussion within the oncology and health economics research communities. Using our combined expertise in health economics research and economic modeling, we structured our inquiry around the following 4 questions: (1) Are economic models adequately addressing questions relevant to oncology decision makers; (2) What are the methodologic limitations of oncology economic models; (3) What guidelines are followed for developing oncology economic models; and (4) Is the evolution of oncology economic modeling keeping pace with treatment innovation? Within the context of each of these questions, we discuss issues related to the technical limitations of oncology modeling, the availability of adequate data for developing models, and the problems with how modeling analyses and results are presented and interpreted. There is general acceptance that economic models are good, essential tools for decision-making, but the practice of oncology and its rapidly evolving technologies present unique challenges that make assessing and demonstrating value especially complex. There is wide latitude for improvement in oncology modeling methodologies and how model results are presented and interpreted. Complex technical and

    The rapid expansion of industry at the outset of economic development and the subsequent growth of the transportation and residential and commercial sectors dictate both the rate at which energy demand increases and the composition of primary fuel sources used to meet secondary requirements. Each of these factors each has an impact on the pollution problems that nations may face. Growth in consumer wealth, however, appears to eventually lead to a shift in priorities. In particular, the importance of the environment begins to take precedent over the acquisition of goods. Accordingly, cleaner energy alternatives are sought out. The approach taken here is to determine the energy profile of an average nation, and apply those results to a model of economic growth. Dematerialization of production and saturation of consumer bundles results in declining rates of growth of energy demand in broadly defined end-use sectors. The effects of technological change in fossil fuel efficiency, fossil fuel recovery, and 'backstop' energy resources on economic growth and the emissions of carbon dioxide are then analyzed. A central planner is assumed to optimize the consumption of goods and services subject to capital and resource constraints. Slight perturbations in the parameters are used to determine their local elasticities with respect to different endogenous variables, and give an indication of the effects of changes in the various assumptions.

  6. Economic Costs and Adaptations for Alternative Regulations of California's Sacramento–San Joaquin Delta

Lund, and Ellen Hanakdoi: http://dx.doi.org/10.15447/sfews.2014v9iss2art4Water exports from California’s Sacramento–San Joaquin Delta are an environmental concern because they reduce net outflows of fresh water from the Delta, and can entrain fish and disrupt flows within the Delta. If exports were no longer pumped from within the Delta, the regulatory issue becomes one of maintaining appropriate flows into and out of the Delta. This paper presents the results of two sets of hydro-economic optimization modeling runs, which were developed to represent a range of modified Delta operations and their economic and operational effects on California’s water supply system. The first set of runs represents decreasing export capacity from the Delta. The second set increases minimum net Delta outflow (MNDO requirements. The hydro-economic model seeks the least–cost statewide water management scheme for water supply, including a wide range of resources and water management options. Results show that reducing exports or increasing MNDO requirements increase annual average statewide water scarcity, scarcity costs, and operating costs (from greater use of desalination, wastewater recycling, water treatment, and pumping. Effects of reduced exports are especially concentrated in agricultural communities in the southern Central Valley because of their loss of access to overall water supply exports and their ability to transfer remaining water to southern California. Increased outflow requirements increase water scarcity and associated costs throughout California. For an equivalent amount of average Delta outflows, statewide costs increase more rapidly when exports alone are reduced than when minimum outflow requirements are increased and effects are more widely distributed statewide.

    Energy use in the developing world has been growing rapidly over recent decades, both absolutely and relative to the growth in industrialized countries albeit from a very low base. In the next century, developing country commercial energy consumption in general and electricity consumption in particular, is expected to continue to rise with striking rapidity because of population growth, income growth and substitution of modern commercial fuels for traditional biomass fuels. Because the power sector is one of the fastest-growing energy sectors, it raises significant domestic environmental issues, while the sector's role in global warming scenarios has made it a key feature of international environmental policy. This paper focuses on the relationships between economic development, electric power and polluting emissions. 10 refs

    The challenge to increase the efficiency in food production level in Nigeria appears to be more urgent now than it has ever been in the history of the country. This is in view of the rapidly increasing population, the imminent decline in international economic and food aid and the need to conserve foreign exchange earnings through the production of raw materials to feed the growing industrial sector calls for urgent attention. The study was carried out in Ogun State. The descriptive statistics was used to determine the socio-economic characteristics of the respondents. The stochastic frontiers production analysis was applied to estimate the technical, allocative efficiency and economic efficiency among the fish farmers in the state. The results of economic efficiency revealed that fish farming is economically efficient with a range of between 55% and 84% efficiency level suggesting a favourable hope for the agro-allied industry such as poultry and cottage industries etc in the state. The result of hypothesis of inefficiency sources models showed that years of experience of fish farmers is significant at 1% probability level indicating the factor contributing to the fish farming experience in the state. Thus, the efficiency is due to the fact that farmers are experienced and fairly educated. On the basis of findings, policy is suggested to be directed towards the encouragement of entrepreneurs in fish farming in the state by providing enabling environment like credit facilities, public enlightenment programme and provision of social amenities like feeder roads, pipe-born water etc and given the fact that an increase in the level of formal education variable leads to less inefficiency, government policy should be focused on adopting the best technology (e.g. fast growing species and equipment) so as to improve the level of efficiency and investment which shall eventually lead to growth in output of fish farming and a lead to the establishment of agro

    We examine the effects of an increase in income on the cohabitation and marriage of single mothers. Using data from an experiment that resulted in randomly assigned differences in child support receipt for welfare-receiving single mothers, we find that exogenous income increases (as a result of receiving all child support that was paid) are associated with significantly lower cohabitation rates between mothers and men who are not the fathers of their child(ren). Overall, these results support the hypothesis that additional income increases disadvantaged women's economic independence by reducing the need to be in the least stable type of partnerships. Our results also show the potential importance of distinguishing between biological and social fathers.

    Full Text Available Although the regional differences of rural economic development can be easily determined, a challenging problem for research studies regarding rural economic development has been the inter-relatedness between different areas, and this challenge has been noted remarkably little in research data to date. As an empirical investigation, this study analyzes the spatio-temporal characteristics of rural economic development from a period beginning in 1978 to the year 2012, in the eastern coastal region of China. In order to determine the special differentiation characteristics of rural economic development, three indexes, namely the Gini coefficient (G, Tsui–Wang index (TW and Theil index (T, were employed. To explore the inter-relatedness among the different areas, we selected a spatial autocorrelation model. The results indicated that, to a large extent, rural economic development from 1978 to 2012 in the eastern coastal region of China was greatly influenced, and the per capita annual net income changed significantly, due to the process of rapid urbanization and industrialization. Generally speaking, the annual net income constantly increased, from 87.7 USD in 1978 to 1628.1 USD in 2012. However, the calculation results indicated that the per capita income gap in the same province decreased, while the gap between the provinces presented an aggregate trend. The regional polarization widened continuously. It was also found that the spatial positive autocorrelation for the regional economy was significant, with a waving and ascending trend, and the neighbor effect of regional economic growth was continuously strengthened. Qualitative analysis of the driving mechanism was applied, and it was determined that there are three primary factors affecting the development of the rural regions, namely resource endowments, economic location and policies.

  13. Transport Infrastructure and Economic Growth: Spatial Effects

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available The author specifies an empirical framework of neoclassical growth model in order to examine impact of transport infrastructure on economic growth in Russian regions during period of 2000-2013. Two different effects of infrastructure are considered. First, infrastructure is viewed as part of region’s own production function. Second, infrastructure generates spillover effect on adjacent regions’ economic performance which can be negative or positive. Results imply that road infrastructure has a positive influence on regional growth, but sign of railroad infrastructure coefficient depends on whether or not congestion effect is considered. Negative spillover effect is shown to exist in the case of road infrastructure. This apparently means that rapid road infrastructure development in some regions moves mobile factors of production away from adjacent regions retarding their economic development. The spillover effect of railroad infrastructure is significant and negative again only if congestion effect is considered. The results of estimation for the Far East and Baikal Regions separately demonstrate no significant effect of both types of infrastructure for economic performance and negative spillover effect of road infrastructure

    economic growth of the Philippines unless the gross domestic investment of GNP ratio is increased substantially. Aggregate output is reduced due to a relatively smaller labor force. Thus, it is suggested that if population control programs are accompanied by an increase in the labor participation rate, particularly of women, the payoffs from family planning may be larger. Closer examination of the nature of the payoffs from the family planning program would reveal that they basically stem from the decrease in the number of persons sharing in national output and not from increased production and saving. The observation suggests that population control does not necessarily lead to more rapid economic growth defined as sustained increase in total output.

  15. Economic implications of Japan's aging population: a macro-economic demographic modeling approach.

    Ogawa, N

    1982-01-01

    This paper utilizes a macroeconomic demographic model to analyze the probable impact of population aging on various public programs in Japan. Rapid fertility decline aided by mortality decline has caused the proportion of the Japanese population aged 65 and over to increase from 4.9% in 1950 to 9.0% in 1980. A population projection based on the 1975 population census assumes a recovery of fertility from a total fertility rate (TFR) of 1.9 in 1976 to 2.16 in 1980 and a gradual decline to 2.1 by 1987, while an alternative projection assumes a continuing fertility decline to a TFR of 1.65 in 2025. According to these assumptions, in 2025 18.12% to 21.29% of the total population would be aged 65 or over and 38.66% to 43.80% of the working age population would be aged 45-64. A macroeconomic neoclassical growth model with some Keynesian features was formulated to evaluate the future impact of population aging on social security programs. Population changes are transmitted to economic variables in the model through the supply of labor, level of savings, public health care plans, and old-age pension schemes. The simulation experiments included the 2 population projections and 2 alternative production functions, 1 with the quality of labor incorporated and 1 without. The results indicated that, regardless of the population projection and production function used, the growth of the economy is likely to slow to 1 or 0% in the beginning of the next century due to decreased growth of the labor force and a change in its quality due to age-compositional variations. Public health insurance schemes and pension plans will require increasing financial resources as a result of accelerated population aging; depending on the choice of benefit levels, the proportion of national income allocated to them is expected to range from 14%-40% in the year 2010. Per capita gross national product will continue to grow despite decreased economic growth, but savings might be adversely affected if the

    The present research documents the widespread misperception of race-based economic equality in the United States. Across four studies ( n = 1,377) sampling White and Black Americans from the top and bottom of the national income distribution, participants overestimated progress toward Black-White economic equality, largely driven by estimates of greater current equality than actually exists according to national statistics. Overestimates of current levels of racial economic equality, on average, outstripped reality by roughly 25% and were predicted by greater belief in a just world and social network racial diversity (among Black participants). Whereas high-income White respondents tended to overestimate racial economic equality in the past, Black respondents, on average, underestimated the degree of past racial economic equality. Two follow-up experiments further revealed that making societal racial discrimination salient increased the accuracy of Whites' estimates of Black-White economic equality, whereas encouraging Whites to anchor their estimates on their own circumstances increased their tendency to overestimate current racial economic equality. Overall, these findings suggest a profound misperception of and unfounded optimism regarding societal race-based economic equality-a misperception that is likely to have any number of important policy implications.

    Transportation decisions have health consequences that are often not incorporated into policy-making processes. Health Impact Assessment (HIA) is a process that can be used to evaluate health effects of transportation policy. We present a rapid HIA, conducted over eight weeks, evaluating health and economic effects of proposed fare increases and service cuts to Boston, Massachusetts' public transportation system. We used transportation modeling in concert with tools allowing for quantification and monetization of multiple pathways. We estimated health and economic costs of proposed public transportation system changes to be hundreds of millions of dollars per year, exceeding the budget gap the public transportation authority was required to close. Significant health pathways included crashes, air pollution, and physical activity. The HIA enabled stakeholders to advocate for more modest fare increases and service cuts, which were eventually adopted by decision makers. This HIA was among the first to quantify and monetize multiple pathways linking transportation decisions with health and economic outcomes, using approaches that could be applied in different settings. Including health costs in transportation decisions can lead to policy choices with both economic and public health benefits.

    Increasing physical activity among children is a potentially important public health intervention. Quantifying the economic and health effects of the intervention would help decision makers understand its impact and priority. Using a computational simulation model that we developed to represent all US children ages 8-11 years, we estimated that maintaining the current physical activity levels (only 31.9 percent of children get twenty-five minutes of high-calorie-burning physical activity three times a week) would result each year in a net present value of $1.1 trillion in direct medical costs and $1.7 trillion in lost productivity over the course of their lifetimes. If 50 percent of children would exercise, the number of obese and overweight youth would decrease by 4.18 percent, averting $8.1 billion in direct medical costs and $13.8 billion in lost productivity. Increasing the proportion of children who exercised to 75 percent would avert $16.6 billion and $23.6 billion, respectively. Project HOPE—The People-to-People Health Foundation, Inc.

    Flood events pose a severe threat to communities in the Lower Mekong River Basin. The combination of population growth, urbanization, and economic development exacerbate the impacts of these flood events. Flood damage assessments are frequently used to quantify the economic losses in the wake of storms. These assessments are critical for understanding the effects of flooding on the local population, and for informing decision-makers about future risks. Remote sensing systems provide a valuable tool for monitoring flood conditions and assessing their severity more rapidly than traditional post-event evaluations. The frequency and severity of extreme flood events are projected to increase, further illustrating the need for improved flood monitoring and impact analysis. In this study we implement a socio-economic damage model into a decision support tool with near real-time flood detection capabilities (NASA's Project Mekong). Surface water extent for current and historical floods is found using multispectral Moderate-resolution Imaging Spectroradiometer (MODIS) 250-meter imagery and the spectral Normalized Difference Vegetation Index (NDVI) signatures of permanent water bodies (MOD44W). Direct and indirect damages to populations, infrastructure, and agriculture are assessed using the 2011 Southeast Asian flood as a case study. Improved land cover and flood depth assessments result in a more refined understanding of losses throughout the Mekong River Basin. Results suggest that rapid initial estimates of flood impacts can provide valuable information to governments, international agencies, and disaster responders in the wake of extreme flood events.

    Full Text Available The approach of economic growth involves understanding the concept and growth factors, respectively, analysing the growth theories, their trend in the context of the development of economic and social life. The economic growth signifies a process aimed at increasing activities in the national economy, expressed by macroeconomic indicators, respectively, the dynamics of the overall Gross Domestic Product or per inhabitant. It can appreciate that, in the short term, this process signifies phases of economic prosperity and on the long-term, expresses an upward trend, a consequence of the succession of increases and decreases. The study presents some elements which outlines the concept of economic growth, that is, definitions, meanings and the main characteristics of the theories of growth, as well as some of its determinant factors. Also, it gives a brief overview of the main theories of economic growth, as they have evolved over time, in line with the economic reality dynamics and the development of the instruments of economic analysis, starting from the classical theories to the new theories and models of economic growth of the modern age.

    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.

    The US Medicare program consumes an ever-rising share of the federal budget. Although this public spending can produce health and social benefits, raising taxes to finance it comes at the cost of slower economic growth. In this article we describe a model incorporating the benefits of public programs and the cost of tax financing. The model implies that the "one-size-fits-all" Medicare program, with everyone covered by the same insurance policy, will be increasingly difficult to sustain. We show that a Medicare program with guaranteed basic benefits and the option to purchase additional coverage could lead to more unequal health spending but slower growth in taxation, greater overall well-being, and more rapid growth of gross domestic product. Our framework highlights the key trade-offs between Medicare spending and economic prosperity.

  8. Obesity and cardiovascular disease in developing countries: a growing problem and an economic threat.

    This review examines the rise of risk factors for cardiovascular disease, especially obesity, in developing countries and the implications for both health and economics. In the majority of developing countries fertility and infant and child mortality have fallen markedly, and life expectancies have increased. Rapid urbanization, falling food prices, and globalization of economies have contributed to an increase in risk factors for chronic disease. Recent work indicates that the prevalence of these risk factors, including obesity, is rising faster than the historical experience of the West. The transition is affecting women in particular, and increases in risk factors are more marked among lower incomes in growing economies than among the wealthy. Rather than the stereotypical problem of the rich, chronic disease is now a problem for the poor. Significant research in this area of global health has only been undertaken in the last decade. Additional field research is needed in every dimension of the transition, both to document the problem itself and to determine its economic and societal impact and cost effective responses. Two critical factors are virtually absent from existing work and should be emphasized. First, the impact of rising risk factors for, and mortality from, cardiovascular disease in the work force may imply a growing threat to continued economic progress. Second, because risk factor reduction requires society-wide strategies, broad public-private coalitions will be needed to mobilize sectors beyond healthcare.

    The effectiveness of disaster risk management and financing mechanisms depends on the accurate assessment of current and future hazard exposure. The increasing availability of detailed data offers policy makers and the insurance sector new opportunities to understand trends in risk, and to make informed decisions on the ways to deal with these trends. In this paper we show how comprehensive property level information can be used for the assessment of exposure to flooding on a national scale, and how this information can contribute to discussions on possible risk financing practices. The case-study used is the Netherlands, which is one of the countries most exposed to flooding globally, and which is currently undergoing a debate on strategies for the compensation of potential losses. Our results show that flood exposure has increased rapidly between 1960 and 2012, and that the growth of the building stock and its economic value in flood prone areas has been higher than in not flood prone areas. We also find that property values in flood prone areas are lower than those in not flood prone areas. We argue that the increase in the share of economic value located in potential flood prone areas can have a negative effect on the feasibility of private insurance schemes in the Netherlands. The methodologies and results presented in this study are relevant for many regions around the world where the effects of rising flood exposure create a challenge for risk financing.

    Research in the field of food intake regulation is gaining importance. This often includes the measurement of peptides regulating food intake. For the correct determination of a peptide's concentration, it should be stable during blood processing. However, this is not the case for several peptides which are quickly degraded by endogenous peptidases. Recently, we developed a blood processing method employing Reduced temperatures, Acidification, Protease inhibition, Isotopic exogenous controls and Dilution (RAPID) for the use in rats. Here, we have established this technique for the use in humans and investigated recovery, molecular form and circulating concentration of food intake regulatory hormones. The RAPID method significantly improved the recovery for (125)I-labeled somatostatin-28 (+39%), glucagon-like peptide-1 (+35%), acyl ghrelin and glucagon (+32%), insulin and kisspeptin (+29%), nesfatin-1 (+28%), leptin (+21%) and peptide YY3-36 (+19%) compared to standard processing (EDTA blood on ice, p processing, while after standard processing 62% of acyl ghrelin were degraded resulting in an earlier peak likely representing desacyl ghrelin. After RAPID processing the acyl/desacyl ghrelin ratio in blood of normal weight subjects was 1:3 compared to 1:23 following standard processing (p = 0.03). Also endogenous kisspeptin levels were higher after RAPID compared to standard processing (+99%, p = 0.02). The RAPID blood processing method can be used in humans, yields higher peptide levels and allows for assessment of the correct molecular form.

    Social instability is a concept that economists rarely analyse, and yet it can lurk behind much economic policy-making. China’s leadership has often publicly expressed its concerns to avoid ‘social instability’. It is viewed as a threat both to the political order and to the continued rapid growth of the economy. This threat to growth in turn endangers the maintenance of social stability. This paper examines the likely economic determinants of social instability, using both surveys and ...

    Asia has witnessed robust economic growth since the 1960s. Today, emerging markets in Asia have managed to maintain rapid growth even when the world's main economies suffer from debt and banking crises. However, declining total fertility rate, increasing life expectancy, continuous change of birth and death patterns, and increasing share of old age population in the age distribution in Asia exert significant pressure on its economies. This paper analyses the relationship between population ageing and economic growth using 2 different panels of countries; one Asian and another the from the oldest countries worldwide between 1970 and 2014. The analysis is based on the Auto Regression Distributed Lag models. The MG (Mean Group) and PMG (Pooled Mean Group) estimations are applied in this analysis. The Hausman Test is conducted to decide between the MG and PMG estimators. We find that ageing will negatively affect the economy in the long run. The growing number of youths will initially have a negative effect on the economy but would eventually lead to a positive growth in the future. The old age dependency ratio has yet to have affect the Asian economy but is expected eventually to impose a negative effect as seen in the oldest nations of the world.

    Recent theory predicts harsh and stochastic conditions to generally promote the evolution of cooperation. Here, we test experimentally whether stochasticity in economic losses also affects the value of reputation in indirect reciprocity, a type of cooperation that is very typical for humans. We used a repeated helping game with observers. One subject (the "Unlucky") lost some money, another one (the "Passer-by") could reduce this loss by accepting a cost to herself, thereby building up a reputation that could be used by others in later interactions. The losses were either stable or stochastic, but the average loss over time and the average efficiency gains of helping were kept constant in both treatments. We found that players with a reputation of being generous were generally more likely to receive help by others, such that investing into a good reputation generated long-term benefits that compensated for the immediate costs of helping. Helping frequencies were similar in both treatments, but players with a reputation to be selfish lost more resources under stochastic conditions. Hence, returns on investment were steeper when losses varied than when they did not. We conclude that this type of stochasticity increases the value of reputation in indirect reciprocity.

    With rapid economic development and urbanization, land use in China has experienced huge changes in recent years; and this will probably continue in the future. Land use problems in China are urgent and need further study. Rapid land-use change and economic development make China an ideal region for integrated land use change studies, particularly the examination of multiple factors and global-regional interactions in the context of global economic integration. This paper presents an integrated modeling approach to examine the impact of global socio-economic processes on land use changes at a regional scale. We develop an integrated model system by coupling a simple global socio-economic model (GLOBFOOD) and regional spatial allocation model (CLUE). The model system is illustrated with an application to land use in China. For a given climate change, population growth, and various socio-economic situations, a global socio-economic model simulates the impact of global market and economy on land use, and quantifies changes of different land use types. The land use spatial distribution model decides the type of land use most appropriate in each spatial grid by employing a weighted suitability index, derived from expert knowledge about the ecosystem state and site conditions. A series of model simulations will be conducted and analyzed to demonstrate the ability of the integrated model to link global socioeconomic factors with regional land use changes in China. The results allow an exploration of the future dynamics of land use and landscapes in China.

    1983-01-01

    Much emphasis is currently being placed in LMFBR design on reducing both the capital cost and the fuel cycle cost of an LMFBR to insure its economic competativeness without a rapid increase in the uranium prices. In this study the relationship between two core design options, their neutronic consequences, and their effect on fuel cycle cost are analyzed. The two design options are the selection of pin diameter and the degree of heterogeneity. In the case of a heterogeneous core, with a low sodium void reactivity worth this ratio of fertile internal blanket to driver assemblies is generally about 0.40. However, some advantages of cores with heterogeneity of 0.08 to 0.2 for a fixed pin diameter have been reported

  19. Spatial Pattern of Residential Carbon Dioxide Emissions in a Rapidly Urbanizing Chinese City and Its Mismatch Effect

    Directory of Open Access Journals (Sweden)

    Heli Lu

    2018-03-01

    Full Text Available Cities undergoing rapid urbanization are characterized by quick successions of spatiotemporal patterns, meaning that traditional methods cannot adequately assess carbon emissions from urban residential areas, which prevents the study of spatial mismatch. Therefore, this study utilizes night-time lights to construct a spatial emissions model that enables the analysis of the evolution of emissions patterns in China. The results indicate that, compared to the traditional method, the spatial modeling based on night-time lights reflects the spatial emissions trajectories in a more timely and accurate manner in rapidly urbanizing cities. Additionally, we found a relatively low degree of spatial match between emissions and economic activities, with the former, which are greatly affected by urbanization, having a larger dynamism and instability than the latter. Such spatial mismatch effect illustrates that policy makers should focus on factors beyond economics in order to reduce residential carbon emissions during China’s rapid urbanization process.

    2013-01-01

    The northern Gulf of Mexico coast of the United States has been identified as highly vulnerable to sea-level rise, based on a combination of physical and societal factors. Vulnerability of human populations and infrastructure to projected increases in sea level is a critical area of uncertainty for communities in the extremely low-lying and flat northern gulf coastal zone. A rapidly growing population along some parts of the northern Gulf of Mexico coastline is further increasing the potential societal and economic impacts of projected sea-level rise in the region, where observed relative rise rates range from 0.75 to 9.95 mm per year on the Gulf coasts of Texas, Louisiana, Mississippi, Alabama, and Florida. A 1-m elevation threshold was chosen as an inclusive designation of the coastal zone vulnerable to relative sea-level rise, because of uncertainty associated with sea-level rise projections. This study applies a Coastal Economic Vulnerability Index (CEVI) to the northern Gulf of Mexico region, which includes both physical and economic factors that contribute to societal risk of impacts from rising sea level. The economic variables incorporated in the CEVI include human population, urban land cover, economic value of key types of infrastructure, and residential and commercial building values. The variables are standardized and combined to produce a quantitative index value for each 1-km coastal segment, highlighting areas where human populations and the built environment are most at risk. This information can be used by coastal managers as they allocate limited resources for ecosystem restoration, beach nourishment, and coastal-protection infrastructure. The study indicates a large amount of variability in index values along the northern Gulf of Mexico coastline, and highlights areas where long-term planning to enhance resiliency is particularly needed.

  2. Detection from space of a reduction in anthropogenic emissions of nitrogen oxides during the Chinese economic downturn

    Lin, J.-T.; McElroy, M. B.

    2011-08-01

    Rapid economic and industrial development in China and relatively weak emission controls have resulted in significant increases in emissions of nitrogen oxides (NOx) in recent years, with the exception of late 2008 to mid 2009 when the economic downturn led to emission reductions detectable from space. Here vertical column densities (VCDs) of tropospheric NO2 retrieved from satellite observations by SCIAMACHY, GOME-2 and OMI (both by KNMI and by NASA) are used to evaluate changes in emissions of NOx from October 2004 to February 2010 identifying impacts of the economic downturn. Data over polluted regions of Northern East China suggest an increase of 27-33 % in 12-month mean VCD of NO2 prior to the downturn, consistent with an increase of 49 % in thermal power generation (TPG) reflecting the economic growth. More detailed analysis is used to quantify changes in emissions of NOx in January over the period 2005-2010 when the effect of the downturn was most evident. The GEOS-Chem model is employed to evaluate the effect of changes in chemistry and meteorology on VCD of NO2. This analysis indicates that emissions decreased by 20 % from January 2008 to January 2009, close to the reduction of 18 % in TPG that occurred over the same interval. A combination of three independent approaches indicates that the economic downturn was responsible for a reduction in emissions by 9-11 % in January 2009 with an additional decrease of 10 % attributed to the slow-down in industrial activity associated with the coincident celebration of the Chinese New Year; errors in the estimate are most likely less than 3.4 %.

  3. Environmentally Sustainable Economic Growth

    Full Text Available Economic growth and sustainable development are important issues for social prosperity. Sustainable development strives for moderate and responsible use within the economic activity of the limited resources of our planet, whereas economic growth does not limit the resource exploitation and energy, being mainly focused on productivity increase. From this perspective, both conceptual and operational contradictions occur between the two pillars of prosperity. This paper looks to these contradictions and proposes some streams of intervention such as economic growth and environmental sustainability to operate in harmony. A structured framework for innovative problem solving is considered in this respect. Results of this research show that it is possible to induce smart measures in the economic system for directing businesses towards new paradigms where economic growth is possible without negative effects on environmental sustainability.

    2016-12-01

    In the Bioenergy and Defense Department of Sandia National Laboratories, characterization of the BaDx (Bacillus anthracis diagnostic cartridge) was performed and rapid germination chemistry was investigated. BaDx was tested with complex sample matrixes inoculated with Bacillus anthracis, and the trials proved that BaDx will detect Bacillus anthracis in a variety of the medium, such as dirt, serum, blood, milk, and horse fluids. The dimensions of the device were altered to accommodate an E. coli or Listeria lateral flow immunoassay, and using a laser printer, BaDx devices were manufactured to identify E. coli and Listeria. Initial testing with E. coli versions of BaDx indicate that the device will be viable as a portable diagnostic cartridge. The device would be more effective with faster bacteria germination; hence studies were performed the use of rapid germination chemistry. Trials with calcium dipicolinic acid displayed increased cell germination, as shown by control studies using a microplate reader. Upon lyophilization the rapid germination chemistry failed to change growth patterns, indicating that the calcium dipicolinic acid was not solubilized under the conditions tested. Although incompatible with the portable diagnostic device, the experiments proved that the rapid germination chemistry was effective in increasing cell germination.

    2012-01-01

    This article reviewed developments of Computerized Numerical Control (CNC) technology in rapid prototyping process. Rapid prototyping (RP) can be classified into three major groups; subtractive, additive and virtual. CNC rapid prototyping is grouped under the subtractive category which involves material removal from the workpiece that is larger than the final part. Richard Wysk established the use of CNC machines for rapid prototyping using sets of 2½-D tool paths from various orientations about a rotary axis to machine parts without refixturing. Since then, there are few developments on this process mainly aimed to optimized the operation and increase the process capabilities to stand equal with common additive type of RP. These developments include the integration between machining and deposition process (hybrid RP), adoption of RP to the conventional machine and optimization of the CNC rapid prototyping process based on controlled parameters. The article ended by concluding that the CNC rapid prototyping research area has a vast space for improvement as in the conventional machining processes. Further developments and findings will enhance the usage of this method and minimize the limitation of current approach in building a prototype.

    2006-01-01

    The dilepton production at backward rapidities in pAu and pp collisions at RHIC and LHC energies is investigated in the dipole approach. The results are shown through the nuclear modification ratio R pA considering transverse momentum and rapidity spectra. The dilepton modification ratio presents interesting behavior at the backward rapidities when compared with the already known forward ones, since it is related with the large x kinematical region that is being probed. The rapidity dependence of the nuclear modification ratio in the dilepton production is strongly dependent on the Bjorken x behavior of the nuclear structure function ratio R F 2 =F 2 A /F 2 p . The R pA transverse momentum dependence at backward rapidities is modified due to the large x nuclear effects: at RHIC energies, for instance, the ratio R pA is reduced as p T increases, presenting an opposite behavior when compared with the forward one. It implies that the dilepton production at backward rapidities should carry information of the nuclear effects at large Bjorken x, as well as that it is useful to investigate the p T dependence of the observables in this kinematical regime

  9. Two-step rapid sulfur capture. Final report

    NONE

    1994-04-01

    The primary goal of this program was to test the technical and economic feasibility of a novel dry sorbent injection process called the Two-Step Rapid Sulfur Capture process for several advanced coal utilization systems. The Two-Step Rapid Sulfur Capture process consists of limestone activation in a high temperature auxiliary burner for short times followed by sorbent quenching in a lower temperature sulfur containing coal combustion gas. The Two-Step Rapid Sulfur Capture process is based on the Non-Equilibrium Sulfur Capture process developed by the Energy Technology Office of Textron Defense Systems (ETO/TDS). Based on the Non-Equilibrium Sulfur Capture studies the range of conditions for optimum sorbent activation were thought to be: activation temperature > 2,200 K for activation times in the range of 10--30 ms. Therefore, the aim of the Two-Step process is to create a very active sorbent (under conditions similar to the bomb reactor) and complete the sulfur reaction under thermodynamically favorable conditions. A flow facility was designed and assembled to simulate the temperature, time, stoichiometry, and sulfur gas concentration prevalent in the advanced coal utilization systems such as gasifiers, fluidized bed combustors, mixed-metal oxide desulfurization systems, diesel engines, and gas turbines.

    Clarke, F.J.P.; Main, F.K.

    1983-01-01

    The original choices of thermal reactors and fuel cycles were largely determined by specific national circumstances and by experience and facilities acquired from defence-related programmes. These led to the development of LWRs in the USA and to the natural uranium/gas/graphite system in the United Kingdom and France, while Canada selected the HWR. Most countries with nuclear power programmes saw the plutonium-fuelled fast reactor, with its breeding potential, as the means to ensure that exhaustion of economic uranium resources would not prematurely curtail the contribution of nuclear power to world energy supplies. Fuel reprocessing was essential to this fuel cycle or indeed to other recycling options to make better use of the available uranium; it was also favoured for waste management reasons. Early expectations of nuclear power growth suggested that a transition from thermal to fast reactors would occur during the present century but the urgency has been reduced by world economic recession, slower increases in nuclear capacity and the continued availability of supplies of low-priced uranium. Reprocessing costs have risen and economics of scale favour large plants, which are therefore most likely to be built in countries with substantial thermal reactor capacities; these countries will be able to provide reprocessing services to others. As the ultimate strategic need for fast reactors has not been reduced by this slowdown it is important to continue the development and demonstration of fast-reactor technology and the associated fuel cycles. Uncertainties in future fuel prices mean that it could be advantageous to introduce fast reactors as soon as they become an economic, although not necessarily the most economic, choice. Notably, fast reactors may be installed initially when and where they become economic compared to coal-fired generation, in order to lay the foundation for more rapid expansion when economic break-even with thermal reactors occurs.

Vehicle operating cost (VOC), value of time (VOT), pollution cost, accident cost and environmental cost are calculated in other to know the benefits for their abilities to ensure accessibility and mobility, reduce accidents and reduce environmental loss. The study stretch involves an 11.1 km of 2-lane divided carriageway road connecting Kabuga bus stop to Janguza market. Social costs which included accident costs, accident cost of cars (private modes) were found to be 50 times the accident cost of bus accidents. California Air Resource Board (CARB) model was adopted to evaluate Environmental costs. The total road user costs were then obtained to provide comparative evaluation among the study modes. Furthermore, the multiple future scenarios were created to provide understanding about the need for inclusion of other modes. In this regard, this paper provided a framework for the cost evaluation for an urban area and results indicate that buses are more cost-effective in transportation of equivalent number of passengers.

    Non-adiabatic rapid passage (NARS) electron paramagnetic resonance (EPR) spectroscopy was introduced by Kittell, A.W., Camenisch, T.G., Ratke, J.J. Sidabras, J.W., Hyde, J.S., 2011 as a general purpose technique to collect the pure absorption response. The technique has been used to improve sensitivity relative to sinusoidal magnetic field modulation, increase the range of inter-spin distances that can be measured under near physiological conditions, and enhance spectral resolution in copper (II) spectra. In the present work, the method is extended to CW microwave power saturation of spin-labeled T4 Lysozyme (T4L). As in the cited papers, rapid triangular sweep of the polarizing magnetic field was superimposed on slow sweep across the spectrum. Adiabatic rapid passage (ARP) effects were encountered in samples undergoing very slow rotational diffusion as the triangular magnetic field sweep rate was increased. The paper reports results of variation of experimental parameters at the interface of adiabatic and non-adiabatic rapid sweep conditions. Comparison of the forward (up) and reverse (down) triangular sweeps is shown to be a good indicator of the presence of rapid passage effects. Spectral turning points can be distinguished from spectral regions between turning points in two ways: differential microwave power saturation and differential passage effects. Oxygen accessibility data are shown under NARS conditions that appear similar to conventional field modulation data. However, the sensitivity is much higher, permitting, in principle, experiments at substantially lower protein concentrations. Spectral displays were obtained that appear sensitive to rotational diffusion in the range of rotational correlation times of 10−3 to 10−7 s in a manner that is analogous to saturation transfer spectroscopy.

    We review the economic benefits and external costs of unconventional gas production (UCG) in the United States from a policy perspective. Based on an overview of state regulation in Pennsylvania, a state that has witnessed very rapid growth of gas production over the past 5 years, and global experiences we present 10 key principles that are proposed to reduce the risks and to increase the net rewards of UCG. Application of these principles has the potential to reduce the risks of UCG, especially at a local level, while maximizing the benefits of gas developments. - Highlights: • SWOT summary of unconventional gas developments. • Risks and returns of unconventional gas highlighted. • 10 principles given to reduce risks and increase rewards of gas extraction.

    Multiple sclerosis (MS) imposes high economic costs on society, but the patients and their families have to bear some of these costs. We aimed to estimate the magnitude of these economic costs in Norway. We collected data through a postal questionnaire survey targeting 922 MS patients in Hordaland County, western Norway, in 2013-2014; 546 agreed to participate and were included. The questionnaire included clinical and demographic characteristics, volume and cost of MS-related resource use, work participation, income, government financial support, and disability status. The mean annual total economic costs for the patients and their families were €11,603. Indirect costs accounted for 66% and were lower for women than for men. The direct costs were nearly identical for men and women. The costs increased up to Expanded Disability Status Scale score 6 except for steps between 3 and 4 where it remained nearly constant. The costs reduced from EDSS 6 to 8, and increased from 8 to 9. Lifetime costs ranged from €24,897 to €70,021 for patients with late disease onset and slow progression, and between €441,934 and €574,860 for patients with early onset and rapid progression. The economic costs of MS impose a heavy burden on the patients and their families. Supplementing the information on the cost of MS to society, our finding should be included as background information in decisions on reimbursing and allocating public resources for the well-being of MS patients and their families.

    Narrative review. To review the common tenets, strengths, and weaknesses of decision modeling for health economic assessment and to review the use of decision modeling in the spine literature to date. For the majority of spinal interventions, well-designed prospective, randomized, pragmatic cost-effectiveness studies that address the specific decision-in-need are lacking. Decision analytic modeling allows for the estimation of cost-effectiveness based on data available to date. Given the rising demands for proven value in spine care, the use of decision analytic modeling is rapidly increasing by clinicians and policy makers. This narrative review discusses the general components of decision analytic models, how decision analytic models are populated and the trade-offs entailed, makes recommendations for how users of spine intervention decision models might go about appraising the models, and presents an overview of published spine economic models. A proper, integrated, clinical, and economic critical appraisal is necessary in the evaluation of the strength of evidence provided by a modeling evaluation. As is the case with clinical research, all options for collecting health economic or value data are not without their limitations and flaws. There is substantial heterogeneity across the 20 spine intervention health economic modeling studies summarized with respect to study design, models used, reporting, and general quality. There is sparse evidence for populating spine intervention models. Results mostly showed that interventions were cost-effective based on $100,000/quality-adjusted life-year threshold. Spine care providers, as partners with their health economic colleagues, have unique clinical expertise and perspectives that are critical to interpret the strengths and weaknesses of health economic models. Health economic models must be critically appraised for both clinical validity and economic quality before altering health care policy, payment strategies, or

    2011-01-01

    If there is one sector in which the state of play has changed radically over a few decades, it is the energy sector. It has been affected simultaneously by the prospect that the main fossil fuels will become exhausted, by the impact on our planet's climate of the consumption of this fossil energy (implying increased recourse to renewable sources) and by the rapid economic development of large nations consuming increasing quantities of energy. Energy-related policies (particularly economic and technological policies) are, in fact, being developed in an increasingly complex and international context, which is, at times, very difficult to grasp. Fortunately, two specialists in energy matters, Jean-Pierre Hansen and Jacques Percebois, have published a very comprehensive survey of this new economic and political state of play in the energy field: 'Energie. Economie et politiques' [Energy: Economics and Policies] (Brussels: De Boeck, 2010). It clearly is not possible here to go into all the questions they confront, but in this review Jacques Lesourne, who has read the book for Futuribles, clearly demonstrates its importance and presents the reader with the main facets of the work that make it a reference tool for all involved in this sector, including the most highly specialized.

    Full Text Available In this paper we examine the performance of investment funds during the period 2006-2010, intending to comprise the portfolio performance’s dynamics before, during and after the present economic and financial crises climax. We categorize investment funds according to their investment strategy and geographical focus and distinguish a number of 11 classes. In order to analyze their returns’ dynamics, we create a fund performance index for each category using principal components method. The instability created in financial system in 2007 had a direct impact on institutional investors’ portfolios regardless of investment strategy, effects that have rapidly propagated on real economy. Analyzing index’s dynamics correlated with economic growth we conclude that financial and economic environment react in the same direction, but with a certain time delay, to instability factors. We also underline the major impact of boom and bust evolution of financial markets on real economy, cause of the current economic and financial crises.

    The Rapid Geophysical Surveyor (RGS) is a system designed to rapidly and economically collect closely-spaced geophysical data used for characterization of Department of Energy (DOE) waste sites. Geophysical surveys of waste sites are an important first step in the remediation and closure of these sites; especially older sties where historical records are inaccurate and survey benchmarks have changed due to refinements in coordinate controls and datum changes. Closely-spaced data are required to adequately differentiate pits, trenches, and soil vault rows whose edges may be only a few feet from each other. A prototype vehicle designed to collect magnetic field data was built at the Idaho national Engineering Laboratory (INEL) during the summer of 1992. The RGS was one of several projects funded by the Buried Waste Integrated Demonstration (BWID) program. This vehicle was demonstrated at the Subsurface Disposal Area (SDA) within the Radioactive Waste Management Complex (RWMC) on the INEL in September of 1992. Magnetic data were collected over two areas in the SDA, with a total survey area of about 1.7 acres. Data were collected at a nominal density of 2 1/2 inches along survey lines spaced 1 foot apart. Over 350,000 data points were collected over a 6 day period corresponding to about 185 man-days using conventional ground survey techniques. This report documents the design and demonstration of the RGS concept including the presentation of magnetic data collected at the SDA. The surveys were able to show pit and trench boundaries and determine details of their spatial orientation never before achieved

    Reproductive performance in young beef cows is often compromised due to a mismatch of physiological demands and suboptimal environmental conditions. Studies conducted at the Corona Range and Livestock Research Center from 2000 to 2007 evaluated 3 postpartum supplement strategies that varied in the amount of glucogenic potential (GP) supplied. Reproductive variables, milk production, and serum metabolites were used to assess supplement effectiveness and economics associated with 2- and 3-yr-old beef cows (n = 379) grazing native range. Supplements were individually fed twice/week at 1,135 g/d (2003 to 2004) or 908 g/d (all other years) and provided 1) 327 g of CP, 109 to 118 g of RUP (CON); 2) 327 to 341 g of CP, 142 to 157 g of RUP (RUP); or 3) 327 g of CP, 151 to 173 g of RUP + 40 to 100 g of propionate salt (PS; RUP+PS). Ultimately, total GP for CON, RUP, and RUP+PS was 44 to 47, 57 to 70, and 93 to 141 g, respectively. Blood samples were collected once/week (2000) or twice/week (2001 to 2007) for progesterone analysis to estimate days to resumption of estrus. Cows were exposed to bulls for 60 d or less, and pregnancy was confirmed by rectal palpation at weaning. Days to resumption of estrus after calving decreased linearly (P = 0.02), resulting in an increased pregnancy rate (P = 0.03) with increasing GP. Milk production exhibited a quadratic (P = 0.04) response to increasing GP, with cows fed RUP producing the most amount of milk. However, a linear decrease (P = 0.07) in days from BW nadir to estrus was found with increasing GP. Total kilograms of calf weaned per cow exposed for the supplemental year and subsequent year was increased linearly (P = 0.07) with increased GP. The improvement in pregnancy rate by supplementing RUP+PS resulted in an increase in total revenue of 18% compared with CON-fed cows and 9.5% compared with RUP-fed cows in the subsequent year after supplementation. These data suggest feeding young cows additional GP in the form of PS allows

    Togo is a developing country whose population is increasing at the rapid rate of 2.7%/year. Economic development is therefore a necessity to ensure at least an average standard of living. Plans of development include objectives of structural societal changes, including improvements in education and employment. This study analyzes the evolution of population activities. It identifies obstacles to the improvement of education and employment. The investigation examines the employment and education situation before adoption of the 2nd plan of Togo and predicts the probable evolution of the situation. Despite the priority accorded to agriculture, the 2nd plan appears to give greater importance to industry. The industrial and commercial sector has witnessed a 65.2% investment increase, whereas the rural sector had an investment increase of 11.8%. The 2nd plan, in view of its relation to the evolution of economic activities, took into account the demand for manual labor. In the private sector, industries should occupy an important position. The dualism of a modern and a traditional sector is considered a cause of underdevelopment. The modern sector should be developed in order to suppress the traditional sector and allow progress in society. As a result of this approach, agriculture is given a 2ndary role.

    The effectiveness of disaster risk management and financing mechanisms depends on an accurate assessment of current and future hazard exposure. The increasing availability of detailed data offers policy makers and the insurance sector new opportunities to understand trends in risk, and to make informed decisions on ways to deal with these trends. In this paper we show how comprehensive property level information can be used for the assessment of exposure to flooding on a national scale, and how this information provides valuable input to discussions on possible risk financing practices. The case study used is the Netherlands, which is one of the countries most exposed to flooding globally, and which is currently undergoing a debate on strategies for the compensation of potential losses. Our results show that flood exposure has increased rapidly between 1960 and 2012, and that the growth of the building stock and its economic value in flood-prone areas has been higher than in non-flood-prone areas. We also find that property values in flood-prone areas are lower than those in non-flood-prone areas. We argue that the increase in the share of economic value located in potential flood-prone areas can have a negative effect on the feasibility of private insurance schemes in the Netherlands. The methodologies and results presented in this study are relevant for many regions around the world where the effects of rising flood exposure create a challenge for risk financing.

    Today`s highly competitive global economy is being driven by increasingly rapid technological development. This paper explores the problems of math and science illiteracy in the United States and the potential impact on our economic survival in this environment during the next century. Established educational methods that reward task performance, emphasize passive lecture, and fail to demonstrate relevance to real life are partly to blame. Social norms, stereotypes, and race and gender bias also have an impact. To address this crisis, we need to question the philosophy of an educational system that values task over concept. Many schools have already initiated programs at all grade levels to make math and science learning more relevant, stimulating, and fun. Teaching methods that integrate math and science learning with teamwork, social context, and other academic subjects promote the development of higher-order thinking skills and help students see math and science as necessary skills.

  11. Application of Self Cleaning Rapid Sand Filter in Water Treatment

    2005-08-01

    Full Text Available Rapid sand filter is one of the most important units in the water treatment plants. It has some difficulties in operation such as backwashing. For the solving of this problem a rapid sand filter has designed and built with the self-cleaning backwashing system. This system consist of 3 main constituents; one galvanized siphon and two galvanized steel tanks. One of them is used for filtration and the other used for the storage of filtrated water in elevation for backwashing the system. Water enter from upside of the filter through the inlet pipe, and collected from the under drainage pipe. Then filter water conduct to the storage tank and exit from outlet pipe. In the beginning, the head loss was low, but because of bed clogging by suspended solids, it increases gradually to the designed head loss (1.2m. Then the system is outed of the service automatically and the backwash is began. The main data for the design of system selected from the hydraulic rules of siphons and rapid sand filter criteria. After essential calculations it was constructed and was started operation. For the hydraulic studies a known volume of storage tank was selected and the time needed for the fill (in filtration stage and empty (in backwash stage of water volume with volumetric method were measured. In hydraulic studies the filter surface rate (SOR was selected about 5-7.5m3/m2/hr (1.39-2.08 lit/sec and the flow of water in siphon, during the backwashing was measured 8.7 lit/sec. It can be seen that the siphon passes 4-6 times the inlet raw water thus a negative pressure will created in the siphon which causes the water above the sand bed to be discharged automatically and rinse water from elevated tank flow under the sand bed and back wash it. So according to this study self cleaning rapid sand filter is very useful for water filtration, especially in small population community. The construction of system is rapid, simple and economic.

It demonstrates that the economic liberalization is an absolute prerequisite for the transition to sustainable socio-economic development. Such development must rely on investment activities of the state, which in the current circumstances is a necessary but not sufficient measure for reversing the negative trends. The negative developments can be prevented only through implementation, along with the institutional changes in the economic area that form a strata of economically independent entrepreneurs-innovators, of no less profound transformation in political institutions aimed at democratization of public life

    A rapidly expanding natural-resource extraction industry and a growing military presence mean an increasingly male-skewed population for the city of Darwin, Australia. This has sparked concerns about the potential for increased violence against women. In this article, we present qualitative research detailing the views of 13 participants from 10 women's support services in the Darwin area. We argue that women's support services bear witness to and are tasked with responding to the impacts of population change on women, yet their work is undermined by uncertainties that stem from neoliberal funding rationales and limited demands on companies to address social issues. © The Author(s) 2016.

    As the needs for fresh water and electricity increases rapidly in Algeria, the Algerian authorities launched a study to assess the potentialities of the introduction of nuclear energy for the production of electricity and potable water. This study which started in 2007, is held under the framework of an IAEA Project untitled: 'techno-economic feasibility study of seawater desalination using nuclear energy' and its objective is to provide a document which will be used to support the government's decision to introduce the nuclear desalination in Algeria. To that end, one site has been selected to host nuclear desalination plant. This site is located in North West region of the country. In this study, we present the results achieved under this project and which corresponds to the economical evaluation of coupling several nuclear reactors: GT-MHR, PBMR, AP1000 and PWR900, with two desalination processes MED and RO. The results are compared with those obtained with fossil energy sources: Natural Gas Turbine and Natural Gas Combined Cycle. (author)

  16. Rapid economic growth leads to boost in NO2 pollution over India, as seen from space

    Science.gov (United States)

    Hilboll, Andreas; Richter, Andreas; Burrows, John P.

    2016-04-01

    Over the past decades, the Indian economy has been growing at an exceptional pace. This growth was induced and accompanied by a strong increase of the Indian population. Consequently, traffic, electricity consumption, and industrial production have soared over the past decades, leading to a strong increase in fuel consumption and thus pollutant emissions. Nitrogen oxides (NO+NO2) are a major component of anthropogenic air pollution, playing key part in reaction cycles leading to the formation of tropospheric ozone. They are mainly emitted by the combustion of fossil fuels; other sources include production by lightning, biomass burning, and microbial activity in soils. Since the mid-1990s, space-borne measurements of tropospheric nitrogen dioxide (NO2) have been conducted by the GOME, SCIAMACHY, GOME-2, and OMI instruments. These instruments perform hyperspectral measurements of scattered and reflected sunlight. Their measurements are then analyzed using differential optical absorption spectroscopy (DOAS) to yield vertically integrated columnar trace gas abundances. Here, we will present the results of 20 years of NO2 measurements over the Indian subcontinent. After showing the spatial distribution of NO2 pollution over India, we will present time series for individual states and urban agglomerations. These time series will then be related to various indicators of economic development. Finally, we will highlight several instances where single industrial pollution sources and their development can clearly be identified from the NO2 maps and estimate their NO2 emissions.

  17. Exploring economic structure and drivers of economic growth in Botswana

    Directory of Open Access Journals (Sweden)

    Patricia Lindelwa Makoni

    2015-12-01

    Full Text Available This article set out to analyse the economic structure and main economic drivers in Botswana. Botswana, a country in sub-Saharan Africa, is a relatively small economy, hugely dependent on its diamond mineral wealth. Concerns have arisen in recent years that the diamond deposits will soon be depleted and the country therefore needs to embark on a diversification programme to broaden its economic base. In order to understand the Botswana economy, its economic structure and current domestic sectorial performance were evaluated, as well as its trends in imports and exports. An analysis of the data shows that, regardless of the awareness of the sensitivity to external shocks of commodity prices, as well as the obvious future depletion of diamond reserves, the Botswana economy continues to rely on diamonds, at the expense of attracting international capital flows to enhance and maintain sustainable economic growth, through investments in agriculture, manufacturing and tourism. It is therefore recommended that the Government of Botswana becomes proactive and implements recommended policies to diversify its economy, so that it can sustain or improve its economic growth by becoming a prime destination of international capital and domestic private sector investment, thereby increasing employment and trade opportunities.

  18. Rapid response learning of brand logo priming: Evidence that brand priming is not dominated by rapid response learning.

    Repetition priming increases the accuracy and speed of responses to repeatedly processed stimuli. Repetition priming can result from two complementary sources: rapid response learning and facilitation within perceptual and conceptual networks. In conceptual classification tasks, rapid response learning dominates priming of object recognition, but it does not dominate priming of person recognition. This suggests that the relative engagement of network facilitation and rapid response learning depends on the stimulus domain. Here, we addressed the importance of the stimulus domain for rapid response learning by investigating priming in another domain, brands. In three experiments, participants performed conceptual decisions for brand logos. Strong priming was present, but it was not dominated by rapid response learning. These findings add further support to the importance of the stimulus domain for the relative importance of network facilitation and rapid response learning, and they indicate that brand priming is more similar to person recognition priming than object recognition priming, perhaps because priming of both brands and persons requires individuation.

  19. Radiobioassay economics and laboratory management

    1983-01-01

    The economic situation faced by laboratories in the US is less than ideal. Inflation/interest rates are in the area of 10 to 20% per year, reimbursement policies are putting pressures on the laboratories, hospitals are in a cost-containment mode in the best of cases, and in the worst, are closing for a lack of funds. In the past six years, there has been a national net loss of 186 hospitals, according to American Hospital Association figures. The pressure is acute on community hospitals; 135 have failed. Many hospitals (160) have applied for federal grants as financially distressed hospitals. Since the community hospitals account for 85% of all admissions in the US, it is obvious that the pressure has been greatest on the hospitals that account for the greatest number of admissions. To put the general economic scene in perspective, according to 1977 Medicare data, 24% of all community hospitals had total expenses that exceeded their total revenues. Many social and economic factors contribute to this picture, but the rapidly rising operating expenses due to inflation, new high cost medical technology, surplus of hospital beds, and inadequate planning, purchasing, accounting, and hiring practices play a noticeable part in contributing to this problem

    The recent technological advances in electron microscopes, detectors, as well as image processing and reconstruction software have brought single particle cryo-electron microscopy (cryo-EM) into prominence for determining structures of bio-molecules at near atomic resolution. This has been particularly true for virus capsids, ribosomes, and other large assemblies, which have been the ideal specimens for structural studies by cryo-EM approaches. An analysis of time series metadata of virus structures on the methods of structure determination, resolution of the structures, and size of the virus particles revealed a rapid increase in the virus structures determined by cryo-EM at near atomic resolution since 2010. In addition, the data highlight the median resolution (∼3.0 Å) and size (∼310.0 Å in diameter) of the virus particles determined by X-ray crystallography while no such limits exist for cryo-EM structures, which have a median diameter of 508 Å. Notably, cryo-EM virus structures in the last four years have a median resolution of 3.9 Å. Taken together with minimal sample requirements, not needing diffraction quality crystals, and being able to achieve similar resolutions of the crystal structures makes cryo-EM the method of choice for current and future virus capsid structure determinations.

    Population aging in Korea is projected to be the most rapid among Organisation for Economic Co-operation and Development (OECD) countries between 2000 and 2050. However, social spending in Korea remains low, reflecting Korea's relatively young population, limited health and long-term care insurance coverage, and immaturity of its pension system.…

    2015-09-01

    The socio-economic and cultural evolution in the last decades encouraged a significant process of transformation of the life conditions in advanced societies, particularly the average duration of the life of the elderly population, which since the second half of the past century has increased by about 60%, becoming from an average of fifty years to about eighty two for women and eighty for men. This phenomenon enables scholars and in particular demography scholars, to assume that in 2030 the number of elderly persons will reach about two billion worldwide. This development of an increasingly longer life expectancy, justifies the trust in the great progress that characterizes our society. The rapid growth of this segment of population, due to the improved living conditions and the related progress in science, technology and medicine, in addition to its positive aspects, also includes negative elements, which already affect the Welfare State and, more generally, the public administration that is called to fill the gaps that the transformation of the family and kinship networks have treated with indifference. The problems of the increasingly long-lived, is not freed from new elements of negativity related to the physical and mental decline that leads to the development of new diseases in addition to those already present, ans is increasingly motivated to seek the best remedies to shorten or eliminate the diseases of the elderly. In this context, Depression assumes a central dimension which will surely be a central concern for the economic, social and health impact and for the multitude of changes that put in crisis many of the traditional institutions. This work aims to analyze through a careful review of the scientific literature, the causes of the spread of this disease, the diagnostic difficulties and possible solutions for prevention and care.

    Slowing the reduction, or increasing the accumulation, of organic carbon stored in biomass and soils has been suggested as a potentially rapid and cost-effective method to reduce the rate of atmospheric carbon increase1. The costs of mitigating climate change by increasing ecosystem carbon relative to the baseline or business-as-usual scenario has been quantified in numerous studies, but results have been contradictory, as both methodological issues and substance differences cause variability2. Here we show, based on 77 standardized face-to-face interviews of local experts with the best possible knowledge of local land-use economics and sociopolitical context in ten landscapes around the globe, that the estimated cost of increasing ecosystem carbon varied vastly and was perceived to be 16-27 times cheaper in two Indonesian landscapes dominated by peatlands compared with the average of the eight other landscapes. Hence, if reducing emissions from deforestation and forest degradation (REDD+) and other land-use mitigation efforts are to be distributed evenly across forested countries, for example, for the sake of international equity, their overall effectiveness would be dramatically lower than for a cost-minimizing distribution.

    There is an urgent need to increase population levels of physical activity, particularly amongst those who are socio-economically disadvantaged. Multiple factors influence physical activity behaviour but the generalisability of current evidence to such 'hard-to-reach' population subgroups is limited by difficulties in recruiting them into studies. Also, rigorous qualitative studies of lay perceptions and perceptions of community leaders about public health efforts to increase physical activity are sparse. We sought to explore, within a socio-economically disadvantaged community, residents' and community leaders' perceptions of physical activity (PA) interventions and issues regarding their implementation, in order to improve understanding of needs, expectations, and social/environmental factors relevant to future interventions. Within an ongoing regeneration project (Connswater Community Greenway), in a socio-economically disadvantaged community in Belfast, we collaborated with a Community Development Agency to purposively sample leaders from public- and voluntary-sector community groups and residents. Individual semi-structured interviews were conducted with 12 leaders. Residents (n = 113), of both genders and a range of ages (14 to 86 years) participated in focus groups (n = 14) in local facilities. Interviews and focus groups were recorded, transcribed verbatim and analysed using a thematic framework. Three main themes were identified: awareness of PA interventions; factors contributing to intervention effectiveness; and barriers to participation in PA interventions. Participants reported awareness only of interventions in which they were involved directly, highlighting a need for better communications, both inter- and intra-sectoral, and with residents. Meaningful engagement of residents in planning/organisation, tailoring to local context, supporting volunteers, providing relevant resources and an 'exit strategy' were perceived as important factors

    The risks and opportunities in the rapidly developing markets in Southeast Asia, China in particular, were discussed. It was asserted that no other region in the world can match the long-term market opportunities that China and Southeast Asia promise. The forces driving the economic development in Southeast Asia were described, including the great potential the region holds for the petrochemical industry. Graphs showing total polyethylene production vs. demand for year 2005 were included as illustrative examples. By 2005, China is projected to be importing almost one-half of the products it consumes. Every country with excess capacity will supply China with polyethylene. The political uncertainties that makes doing business in the region a high risk undertaking were reviewed, along with other risks relevant to the petrochemical industry such as (1) high capital costs, (2) over-building to the point that there is more supply than demand for the product, (3) low-cost producers may drive down prices to maintain market share, and (4) the uncertain nature of projections regarding economic growth and (5) inflated estimates of demand for petrochemicals. 1 tab., 4 figs

    Could social media data aid in disaster response and damage assessment? Countries face both an increasing frequency and an increasing intensity of natural disasters resulting from climate change. During such events, citizens turn to social media platforms for disaster-related communication and information. Social media improves situational awareness, facilitates dissemination of emergency information, enables early warning systems, and helps coordinate relief efforts. In addition, the spatiotemporal distribution of disaster-related messages helps with the real-time monitoring and assessment of the disaster itself. We present a multiscale analysis of Twitter activity before, during, and after Hurricane Sandy. We examine the online response of 50 metropolitan areas of the United States and find a strong relationship between proximity to Sandy's path and hurricane-related social media activity. We show that real and perceived threats, together with physical disaster effects, are directly observable through the intensity and composition of Twitter's message stream. We demonstrate that per-capita Twitter activity strongly correlates with the per-capita economic damage inflicted by the hurricane. We verify our findings for a wide range of disasters and suggest that massive online social networks can be used for rapid assessment of damage caused by a large-scale disaster.

    Full Text Available Trade liberalization is closely related to the opening of market access for Indonesian products to the world and vice versa. Since the soybean trade out of BULOG control began in 1998, soybean imports increased very rapidly (Sudaryanto and Swastika, 2007. This research aims to determine the general picture of soybean economy, factors analyses that influence the economic performance of Indonesian soybean and findings the alternative of policies that can reduce soybean imports in Indonesia. Methods of data analysis are descriptive analysis, 2SLS simultaneous equations, and simulation of policy alternatives. Results of the analysis of the factors that affect the economic performance of Indonesian soybean, consists of 1 The area of soybean harvest is influenced significantly by the price of domestic soybean and domestic prices of corn, 2 Productivity soybean influenced significantly by the domestic prices of soybean and fertilizer prices, 3 soybean demand influenced significantly by population, domestic prices of soybean, 4 domestic prices of soybean significantly affected by world prices of soybean, exchange rates, and soybean supply, 5 Imports of soybean influenced significantly by the domestic demand of soybean and soybean production. Therefore, policy scenarios should be made to reduce soybean imports, including by carrying out the expansion of soybean harvest policy, the policy of increasing the productivity of soybean, the policy of subsidizing the price of fertilizer.

  13. Intergenerational aspects of government policy under changing demographic and economic conditions.

    1987-07-01

    Changing demographic and economic conditions in the US require that attention be given to some of the intergenerational equity features of government policy. In particular, social insurance programs and public debt leave public liabilities to future generations. Taken in the aggregate, the effects of rapidly rising public debt and especially social insurance programs are transferring substantial amounts of resources from younger working generations to the expanding generation of retirees. The most crucial element in evaluating the desirability of intergenerational wealth distribution in the long run is the rate of economic growth. A society's monetary, fiscal, tax, and regulatory policies can be more or less conducive to the generation of capital formation, technical change, and economic growth. Policies that influence growth and interest rates will combine with the national deficit to determine how rapidly the debt grows or shrinks. Present accounting procedures are insufficient to provide quantitative answers to the question of what is the impact of a given program on the age-specific distributions of resources. It is important to reconsider the desirability and efficiency of intergenerational redistributions of wealth in the US. It is likely that current policies are not in line with the principles of efficiency, equity, target effectiveness, and cost effectiveness.

  16. Economic and hydrogeologic disparities govern the vulnerability of shared groundwater to strategic overdraft

    Science.gov (United States)

    Mullen, C.; Muller, M. F.

    2017-12-01

    Groundwater resources are depleting globally at an alarming rate. When the resource is shared, exploitation by individual users affects groundwater levels and increases pumping costs to all users. This incentivizes individual users to strategically over-pump, an effect that is challenging to keep in check because the underground nature of the resource often precludes regulations from being effectively implemented. As a result, shared groundwater resources are prone to tragedies of the commons that exacerbate their rapid depletion. However, we showed in a recent study that the vulnerability of aquifer systems to strategic overuse is strongly affected by local economic and physical characteristics, which suggests that not all shared aquifers are subject to tragedies of the commons. Building on these findings, we develop a vulnerability index based on coupled game theoretical and groundwater flow models. We show that vulnerability to strategic overdraft is driven by four intuitively interpretable adimensional parameters that describe economic and hydrogeologic disparities between the agents exploiting the aquifer. This suggests a scale-independent relation between the vulnerability of groundwater systems to common-pool overdraft and their economic and physical characteristics. We investigate this relation for a sample of existing aquifer systems and explore implications for enforceable groundwater agreements that would effectively mitigate strategic overdraft.

The hypothesis is that the targeted efforts of all participants of IEA of the region (business, authorities, local community to strengthen of theese components of the institutional factor, which have a strong influence on the regional socio-economic development. A methodological approach for the assessment of this influenceis developed. It includes determining three elements of IEA institutionalization—agreements, organizations, events. A three-dimensional model is proposed for the coordination of these elements with 3 groups of countries—developed, developing and CIS, including the Eurasian Economic Union, and also with basic indexes characterizing the qualitative and quantitative contribution of region’s IEA into its socio-economic development. This model is tested on the example of the Sverdlovsk region of Russia for 2003–2015. That has allowed to define various kinds of the effects from strenthening the IEA institutional component, which are expressed in the increase of the export of the region, improvement of its investment attractiveness, the diversification of regional economy as well as the the generation of additional jobs and tax flows increase.

    2013-01-01

    Health economics has been an established feature of the research, policymaking, practice and management in the delivery of healthcare. However its role is increasing as the cost of healthcare begins to drive changes in most healthcare systems. Thus the output from cost effectiveness studies is now being taken into account when making reimbursement decisions, e.g. in Australia and the United Kingdom. Against this background it is also recognised that the health economic tools employed in healthcare, and particularly the output from the use of these tools however, are not always employed in the routine delivery of services. One of the notable consequences of this situation is the poor record of innovation in healthcare with respect to the adoption of new technologies, and the realisation of their benefits. The evidence base for the effectiveness of diagnostic services is well known to be limited, and one consequence of this has been a very limited literature on cost effectiveness. One reason for this situation is undoubtedly the reimbursement strategies employed in laboratory medicine for many years, simplistically based on the complexity of the test procedure, and the delivery as a cost-per-test service. This has proved a disincentive to generate the required evidence, and little effort to generate an integrated investment and disinvestment business case, associated with care pathway changes. Point-of-care testing creates a particularly challenging scenario because, on the one hand, the unit cost-per-test is larger through the loss of the economy of scale offered by automation, whilst it offers the potential of substantial savings through enabling rapid delivery of results, and reduction of facility costs. This is important when many health systems are planning for complete system redesign. We review the literature on economic assessment of point-of-care testing in the context of these developments.

    With the excessive development of social economy, water scarcity and water environment deterioration become a common phenomenon in metropolis. As a crucial component of urban water environment system, urban lake is mainly influenced by social economic system and tourism system. In this paper, a framework for quantitatively evaluating development sustainability of urban lake was established by a multi-objective model that represented water ecological carrying capacity (WECC). And nine key indicators including population, irrigation area, tourist quantity, the average number of hotel daily reception, TP, TN, CODMn, BOD5 were chosen from urban social-economy system and natural resilience aspects, with their index weight was determined by using the Structure Entropy Weight method. Then, we took Wuhan East Lake, the largest urban lake in China as a case study, and selected five time sections including 2002, 2004, 2007, 2009 and 2012 to synthetically evaluate and comparatively analyze the dynamic change of WECC. The results showed that: firstly, the water ecological carrying capacity values of the East Lake in five time sections were 1.17, 1.07, 1.64, 1.53 and 2.01 respectively, which all exceeded 1 and increased fluctuation. The rapid growth of population and GDP lead to sharply increasing demand for water quantity. However, a large amount of the domestic sewage and industrial waste led by economic development increases pressure on ecological environment of urban lakes. Secondly, the carrying capacity of the East Lake for tourist activities was still low. The value in 2012 was only 0.22, keeping at a slowly increasing phase, which indicates that the East Lake has large opportunity and space for developing the water resource carrying capacity and could make further efforts to attract tourists. Moreover, the WECC of the East Lake was mainly affected by rapid social and economic development and water environment damage caused by organic pollutants. From the view of urban

    Chronic disease management has been a rapidly growing entity in the 21st century as a strategy for managing chronic illnesses in large populations. However, experience has shown that disease management programs have not been able to demonstrate their financial value. The objectives of disease management programs are to create quality benchmarks, such as principles and guidelines, and to establish a uniform set of metrics and a standardized methodology for evaluating them. In order to illuminate the essence of disease management and its components, as well as the complexity and the problematic nature of performing economic calculations of their profitability and value, we collected data from several reports that dealt with the economic intervention of disease management programs. The disease management economic evaluation is composed of a series of steps, including the following major categories: data/information technology, information generation, assessment/recommendations, actionable customer plans, and program assessment/reassessment. We demonstrate the elements necessary for economic analysis. Disease management is one of the most innovative tools in the managed care environment and is still in the process of being defined. Therefore, objectives should include the creation of quality measures, such as principles and guidelines, and the establishment of a uniform set of metrics and a standardized methodology for evaluating them.

                  Effect of credit on economic growth, unemployment and poverty provides evidence from Indonesia on the role of banks credit for promoting economic growth and reducing both unemployment and poverty.  To document the link between banks credit and economic growth, we estimate a VAR model and variance decompositions of annual GDP per capita growth rates to examine what proxy measures of banks credit are most important in accounting for economic growth over time and how much they contribute to explaining economic growth.  We also estimate an ECM to document the relationship between banks credit to both unemployment and poverty.  This paper revealed bi-direction causality between banks credit and economic growth.  Banks credit promotes economic growth and economic growth affects credit depth and financial development.  Furthermore, banks credit is a growth accelerating factor on Indonesian economic growth.  Banks credit is an endogenous growth and a good predictor on Indonesian economy. Our estimation model explained that credit allocated by banks increases business escalation to the real sectors then promotes economic growth, decreases unemployment rate through increasing in labor demanded, increases income and then decrease poverty.  This overall transmission mechanism just occurred through presence of banks credit by increasing money supply to the real sectors, promotes growth and social welfare.   Keywords :  banks credit, economic growth, growth accelerating factor, poverty, unemployment   JEL Classification : E51, E52, E58

    2005-11-21

    A systematic study of heat treatments and magnetic hardening of NdFeB-based melt-spun nanocomposite ribbons have been carried out. Comparison was made between samples treated by rapid thermal annealing and by conventional furnace annealing. Heating rates up to 200 K s{sup -1} were adopted in the rapid thermal processing. It was observed that magnetic hardening can be realized in an annealing time as short as 1 s. Coercivity of 10.2 kOe in the nanocomposites has been obtained by rapid thermal annealing for 1 s, and prolonged annealing did not give any increase in coercivity. Detailed results on the effects of annealing time, temperature and heating rate have been obtained. The dependence of magnetic properties on the annealing parameters has been investigated. Structural characterization revealed that there is a close correlation between magnetic hardening and nanostructured morphology. The coercivity mechanism was also studied by analysing the magnetization minor loops.

    Although natural populations may evolve resistance to anthropogenic stressors such as pollutants, this evolved resistance may carry costs. Using an experimental evolution approach, we exposed different Daphnia magna populations in outdoor containers to the carbamate pesticide carbaryl and control conditions, and assessed the resulting populations for both their resistance to carbaryl as well as their susceptibility to infection by the widespread bacterial microparasite Pasteuria ramosa. Our results show that carbaryl selection led to rapid evolution of carbaryl resistance with seemingly no cost when assessed in a benign environment. However, carbaryl-resistant populations were more susceptible to parasite infection than control populations. Exposure to both stressors reveals a synergistic effect on sterilization rate by P. ramosa, but this synergism did not evolve under pesticide selection. Assessing costs of rapid adaptive evolution to anthropogenic stress in a semi-natural context may be crucial to avoid too optimistic predictions for the fitness of the evolving populations. © 2011 The Author(s).

Currently, the core of the financial crisis is the low function of financial system, so to make the financial department normal by rebuilding the untrue financial system is the problem we are facing. If our financial sector delay the structural adjustment and continue to be competitive in credit, the insolvent debenture will soar. Enterprise and financial institute closed one after another, causing economic collapse and the vicious circle. Accordingly, in order to overcome the current South-East Asia financial crisis, countries there put their focus on the rebuilding of financial system and under the financial system of IMF (International Monetary Foundation, they are doing economic adjustment in large-scale. This thesis studied the nature and features of the Asian financial crisis, and analyzed the main direction and feature of financial policy under IMF.

    Full Text Available The authors investigated how economic growth affects the disparity in the distribution of regional income in Poland and vice versa. The research was based on annual data covering the period 2000-2009. In general, the research was divided into two main parts. First, the authors examined the evolution of the level of spatial inequalities in income in Poland over the last decade using the concepts of sigma and beta convergence. Next the nature of causal dependences was investigated between this inequality and economic growth. It was found that Polish regions did not converge with respect to the distribution of income as total GDP grew. The second part of the research provided evidence to claim that this inequality caused growth. Moreover, the evidence was also found that growth affected regional inequality. Finally, the authors noticed that the effects of both these factors were positive. The results suggest that as a consequence of rapid economic growth, some regions in Poland seized new opportunities, while less developed regions were unable to keep up with the challenging requirements of a decade of fast economic growth.

  13. A Pedagogical Note on Modeling the Economic Benefit of Emissions Abatement vs. the Economic Harm from Emissions

    OpenAIRE

    2012-01-01

    The number of undergraduate-level textbooks on environmental economics has increased in recent years, but the textbook treatment of optimal emissions (abatement) varies markedly from textbook to textbook. In particular, there is no consensus as to whether to model the economic “bad” (i.e. emissions) or the economic “good” (abatement). This inconsistency can lead to some needless confusion for students introduced to environmental economics for the first time, particularly those students outsid...

  14. Introduction to health economics and decision-making: Is economics relevant for the frontline clinician?

    2013-12-01

    In a climate of escalating demands for new health care services and significant constraints on new resources, the disciplines of health economics and health technology assessment (HTA) have increasingly been turned to as explicit evidence-based frameworks to help make tough health care access and reimbursement decisions. Health economics is the discipline of economics concerned with the efficient allocation of health care resources, essentially trying to maximize health benefits to society contingent upon available resources. HTA is a broader field drawing upon several disciplines, but which relies heavily upon the tools of health economics and economic evaluation. Traditionally, health economics and economic evaluation have been widely used at the political (macro) and local (meso) decision-making levels, and have progressively had an important role even at informing individual clinical decisions (micro level). The aim of this paper is to introduce readers to health economics and discuss its relevance to frontline clinicians. Particularly, the content of the paper will facilitate clinicians' understanding of the link between economics and their medical practice, and how clinical decision-making reflects on health care resource allocation.

    Tropical lowland rainforests are increasingly threatened by the expansion of agriculture and the extraction of natural resources. In Jambi Province, Indonesia, the interdisciplinary EFForTS project focuses on the ecological and socio-economic dimensions of rainforest conversion to jungle rubber agroforests and monoculture plantations of rubber and oil palm. Our data confirm that rainforest transformation and land use intensification lead to substantial losses in biodiversity and related ecosystem functions, such as decreased above- and below-ground carbon stocks. Owing to rapid step-wise transformation from forests to agroforests to monoculture plantations and renewal of each plantation type every few decades, the converted land use systems are continuously dynamic, thus hampering the adaptation of animal and plant communities. On the other hand, agricultural rainforest transformation systems provide increased income and access to education, especially for migrant smallholders. Jungle rubber and rubber monocultures are associated with higher financial land productivity but lower financial labour productivity compared to oil palm, which influences crop choice: smallholders that are labour-scarce would prefer oil palm while land-scarce smallholders would prefer rubber. Collecting long-term data in an interdisciplinary context enables us to provide decision-makers and stakeholders with scientific insights to facilitate the reconciliation between economic interests and ecological sustainability in tropical agricultural landscapes. © 2016 The Authors.

  16. Thermal design and technical economical and environmental analyses of a hydrogen fired multi-objective cogeneration system

    2007-01-01

    Approximately 85% of rapidly increasing world energy demand is supplied by fossil fuels. Extreme usage of fossil fuels causes serious global warming and environmental problems in form of air, soil and water pollutions. The period, in which fossil fuel reserves are decreasing, energy costs are increasing rapidly and new energy sources and technologies do not exist on the horizon, can be called as the expensive and critical energy period. Hydrogen becomes a matter of primary importance as a candidate energy source and carrier in the critical energy period and beyond to solve the energy and environmental problems radically. In this respect, the main obstacle for the use of hydrogen is the high cost of hydrogen production, which is expected to be decreased in the feature. The aim of this study is to examine how hydrogen energy will be able to be integrated with the existing energy substructure with technical and economical dimensions. In this sense, a multi objective hydrogen fired gas turbine cogeneration system is designed and optimized. Technical and economical analyses depending on the load conditions and different hydrogen production cost are carried out. It is possible that the co-generated heat is to be marketed for residence and industrial plants in the surrounding at or under market prices. The produced electricity however can only be sold to the public grid at a high unit support price which is only obtainable in case of the development of new energy technologies. This price should however be kept within the nowadays supportable energy price range. The main mechanism to be used during the design stage of the system to achieve this goal is to decrease the amortization and operational costs which lead to decrease investment and fuel costs and to increase the system load factor and co-generated heat revenues

    2013-04-15

    The energy sector is a key driver of the economic pillar of Vision 2030. As the economy grows, urbanization intensifies and incomes increase, corporate and household demand for energy also rises. To meet this growth in demand for energy, the sector needs to increase investments and diversify into more sources of energy such as geothermal and wind power. It is therefore critical that focus is directed towards development and sustainability of the energy sector to ensure delivery of least cost power that will improve Kenya's competitiveness and achieve the Vision 2030 objective of 10% average annual economic growth.

This study places more emphasis on the causality running from economic growth to financial development contrary to the mainstream view, which asserts that the well-functioning financial systems exert a large positive impact on economic growth via two channels- capital accumulation and technological innovations. The reverse causality is postulated by considering two factors in developments of the country's financial system. Firstly, this paper argues that the rapid accumulation of financial assets and the remarkable expansion of the financial system during the examined period are due primarily to income rises and changes in industrial structures rather than inefficient financial reforms. Secondly, it is recognized in this study that various financial reform measures undertaken by the state since 1994 are emerged endogenously in response to Chinese financial disorders and macroeconomic imbalances built up during the 1979~93 period. This line of thinking is not following the mainstream view in which financial reforms are regarded as policy variables (or exogenous variables in promoting economic growth. These two factors imply that the causality may run from economic growth to financial development at least in China.

    2012-02-01

    The prospects of rapid climate change and the potential existence of tipping points in marine ecosystems where nonlinear change may result from them being overstepped, raises the question of strategies for coping with ecosystem change. There is broad agreement that the combined forces of climate change, pollution and increasing economic activities necessitates more comprehensive approaches to oceans management, centering on the concept of ecosystem-based oceans management. This article addresses the Norwegian experience in introducing integrated, ecosystem-based oceans management, emphasizing how climate change, seen as a major long-term driver of change in ecosystems, is addressed in management plans. Understanding the direct effects of climate variability and change on ecosystems and indirect effects on human activities is essential for adaptive planning to be useful in the long-term management of the marine environment.

    Full Text Available This paper examines the link between health indicators, environmental variables and economic development, and th e consequences of this relationship on economic convergence for a large sample of rich and poor countries. While in economic literature income and environment are seen to have an inverted-U shaped relationship (Environment Kuznets Curve hypothesis, it is also well established that an improvement in environmental quality is positively related to health. Our study focuses on the implications of this relationship for economic convergence. In the early stage of economic development, the gain from income growth could be cancelled or mitigated by environmental degradation through populations' health (and other channels and create a vicious circle in economic activity unlike in developed countries. This in turn could slow down economic convergence. To empirically assess these issues, we proceeded to an econometric analysis through three equations: a growth equation, a health equation and an environment equation. We found that health is a channel through which environment impacts economic growth. When we take into account the effect of environment quality on economic growth, the speed of convergence tends to increase slightly. This shows that environmental quality could be considered as a constraint for economic convergence.

    The computational complexity and problem sizes of power grid applications have increased significantly with the advent of renewable resources and smart grid technologies. The current paradigm of solving these issues consist of inhouse high performance computing infrastructures, which have drawbacks of high capital expenditures, maintenance, and limited scalability. Cloud computing is an ideal alternative due to its powerful computational capacity, rapid scalability, and high cost-effectiveness. A major challenge, however, remains in that the highly confidential grid data is susceptible for potential cyberattacks when outsourced to the cloud. In this work, a security and cloud outsourcing framework is developed for the Economic Dispatch (ED) linear programming application. As a result, the security framework transforms the ED linear program into a confidentiality-preserving linear program, that masks both the data and problem structure, thus enabling secure outsourcing to the cloud. Results show that for large grid test cases the performance gain and costs outperforms the in-house infrastructure.

    Although the departure of children from the parental home is an important life-cycle event, few studies have investigated nest-leaving in developing countries. Using retrospective data from the Second Malaysian Family Life Survey, we estimate hazard models of nest-leaving in Peninsular Malaysia. We find that the departure of children, especially sons, responds to economic incentives, including housing costs, family businesses, education, and economic growth, and that ethnic differences in nest-leaving are important. We also find that the median age of departure from home has declined sharply over the past 40 years, a period of rapid social and economic change in Malaysia.

    Full Text Available The generation of metropolis is the inevitable outcome of the development of urbanization to a certain stage. The economy and society of metropolis are in the rapid development, but this process brings great pressure to the ecological environment, especially the water resources environment at the same time. In this paper, the relationship between metropolitan economic system and water environmental system is deeply studied, and the concept of “coupling” is introduced. Based on the framework of “pressure-state-response” (PSR, 12 detailed indexes, such as total population and water consumption per ten thousand Yuan GDP, were selected to construct four subsystems. The coordination degree measurement model has been used to calculate the degree of coupling between the economic system and water environmental system. On this basis, the following conclusions are drawn through the example of Beijing city: (1 In the process of metropolitan development, the economic system and the water environmental system are interrelated and there exist a complex coupling mechanism. (2 With the adjustment of economic structure and the progress of technology, the coupling index between the metropolitan economic system and the water environmental system has been increasing, and this process shows an upward trend

    Financial and welfare economic analyses are conducted of 15 different biogas production scenarios that vary in terms of plant size and type of input. All considered scenarios lead to welfare economic losses. Overall welfare economic GHG reduction costs seem to increase with increasing crop/crop material share of input, and although the costs vary significantly across scenarios they are quite high for all scenarios. The financial analyses suggest that biogas production generally will be financially profitable for the agricultural sector and local CHP facilities but unprofitable for the biogas plants and the State. Seen from a policy perspective the results highlights the importance of designing regulatory instruments in a way that create incentives for private actors to engage in welfare economically desirable biogas production activities while discouraging the expansion of welfare economically undesirable activities.

    2017-01-01

    To date, real cost data for Electric Vehicle (EV) rapid charging infrastructure is largely missing in the literature, preventing development of economic models to encourage private investment and limiting policy decisions. A business model has been constructed using actual capital expenditure, operating costs and usage data from the Rapid Charge Network project (RCN) which can be used to assist future investment and policy decisions. The model is run under a wide spectrum of EV uptake scenarios to provide plausible answers to a variety of research, policy and investment questions, including minimum growth rates to break even under current policy. Using real-world data we have confirmed that a financial business opportunity does exist for investment in rapid chargers on main highways and have identified the operating area in which a profit can be made. However, since UK EV adoption is still at the Innovators stage in a niche market where innovations in technology, user practices, supporting infrastructure and functionality are still required to achieve wide user acceptance, the case is also made for continued fiscal incentives to encourage investment in rapid-charging infrastructure. - Highlights: • Uses actual cost and use data to propose credible business model for EV rapid charging. • Identifies a profit area for successful operation. • Applying 3.3 electricity mark-up over 10 year investment period gives financial return. • EV uptake and Drivers’ willingness to pay remain key constraints. • Fiscal incentives would encourage private investment where demand is uncertain.

    A reduction of about 30% in the sulfur out-lets in Europe would lead to approximately the same reduction in acid precipitation in the South of Norway. The resulting improvement of water quality would facilitate improvements in the fish population. The report discussed various methods of measuring the socio-economic value of an assumed marginal increase of the amount of fresh water fish and recommends a ''parcel of methods'' in order to solve the estimation problem. A reduction of 30% in the acid precipitation would result in a total yearly socio-economic value increase of approximately 37 millions Norwegian kroners measured by the total willingness of payment by the Norwegian population - wich probably is an underestimation. 66 references, 22 drawings, 5 tables.

    Rapidly curable electrically conductive clear coatings are applied to substrates. The electrically conductive clear coating includes to clear layer having a resinous binder with ultrafine non-stoichiometric tungsten oxide particles dispersed therein. The clear coating may be rapidly cured by subjecting the coating to infrared radiation that heats the tungsten oxide particles and surrounding resinous binder. Localized heating increases the temperature of the coating to thereby thermally cure the coating, while avoiding unwanted heating of the underlying substrate.

    Full Text Available The paper discloses the understanding of new reality (normality for Russia that consists in the strengthening of the role of a man-personality and in the expansion of the economic autonomy of the territories in their interaction with the federal center. The rationale is based on a hypothesis according to which in the conditions of new reality, the increase of the well-being of the population and the overcoming of economic inequality between the territories are provided by the expansion of their economic independence as it leads to the increase of their intellectual, engineering and manufacturing potential. In the research, the author used the basic concepts of the classical economic theory, the theory of behavioural economics, interdisciplinary approach and statistical grouping method. The dynamics of the economic independence of the territories, which is manifested in the decrease in a number of donor regions and the socio-economic dividing of the territories, is shown. The assumption is proved that the consequences of the territorial stratification are the restraining of the growth of their socio-economic development and possibility probable emergence of «regional peripheral economy» with the property of the dependence of the periphery on the center, the decrease in a local initiative, the inhibition of technological development. The need to use the social psychology of the population, the psychological sets of economic development, «the second invisible hand of the market» and soft power to overcome the «regional peripheral economy» is revealed. The result of the research is the proof that the expansion of the economic independence of the territories is not only the increase of the self-isolation of regions and municipalities, but also the need to save the considerable part of the income from the production of goods and services created by the local population under control of the regional and municipal authorities and direct it to the

    2005-01-01

    The price of electricity is significantly influenced by the cost of the initial generation asset. The cost of the initial nuclear generation asset is significantly influenced by the design and construction duration. Negative variations in the cost and duration of actual design and construction have historically impacted the early relative economics of nuclear power generation. Successful management of plant design information will mitigate the risks of the design and construction of future nuclear plants. Information management tools that can model the integrated delivery of large complex projects enable the project owners to accurately evaluate project progress, as well as the economic impact of regulatory, political, or market activities not anticipated in the project execution plan. Significant differences exist in the electrical energy markets, project delivery models, and fuel availability between continents and countries. However, each market and project delivery model is challenged by the need to produce economical electrical energy. The information management system presented in this paper provides a means to capture in a single integrated computerized database the design information developed during plant design, procurement, and construction and to allow this information to be updated and retrieved in real time by all project participants. Utilization of the information management system described herein will enable diverse project teams to rapidly and reliably input, share, and retrieve power plant information, thereby supporting project management's goal to make good on its commitment to the economic promise of tomorrow's nuclear electrical power generation by achieving cost-effective construction.

    Full Text Available This paper intends to render several important factors of impact on economic growth and to describe the particular types of relationships of the latter with each one of its influencing elements. In order to correctly determine such issue, we have resorted to three carefully selected models that have been estimated and compared so as to identify the most adequate and representative regression. For this purpose we have performed an analysis based on cross-section annual data for 105 countries spread all over the world. After having tested and rejected certain exogenous variables initially considered, such as imports or exports, we have finally retained the external debt and foreign direct investments as explanatory items of the dependent variable. The results revealed that both of them positively affect the gross domestic product of the analysed countries, this one being inelastic in relation to the exogenous variables considered. Even if the relationship between the economic growth and the external debt of a country is usually negative, as the money exit out of the country due to the debt service causes non-achieved potential investments, yet, there is an inflexion point up to which the external debt has a positive influence on economic growth by the increase of the investments funds acquired as result of the external credit contracting, this being the case reflected by our study. As for the relationship existing between foreign direct investments and GDP, the economic theory confirms that FDI and economic growth are directly correlated, the former contributing to technical progress, production increase and, finally, to the improvement of the living standard.

    Full Text Available The problem of finding effective economic instruments for socio-economic development of the regions has recently become of increasing relevance. Strengthening the regional differentiation, highlighting the leading and lagging regions, the lack of own resources in the regions has forced regional authorities to use new instruments of territorial development, in particular, economic mechanisms of protection against pension risks. The use of these mechanisms has a dual effect (economic and social, due to the attraction of the regions with additional financial resources in the form of “long money” and increasing the protection of citizens against pension risks (the increase in the level of pension payments. The analysis of the current use of economic mechanisms of protection against pension risks in the regions of the Southern Federal District helped to articulate key issues of their use, in particular, low pension literacy of the population, distrust towards specialized financial institutions, the investment policy of the regions does not take into account the possibility of attracting private pension funds into regional projects, and there is no mechanism to support regional National Pension Fund. Territorial analysis revealed the potential application of economic mechanisms to protect against pension risks in the regions of the Southern Federal District as a tool for socio-economic development, which is based on the existence of regional pension funds and insurance companies (providing services for pension insurance, as well as participation in private pension provision. The Krasnodar, Rostov and Volgograd regions have the highest potential among the regions of the Southern Federal District, as there already exist regional National Pension Fund, and the participation in private pension insurance is confirmed by the statistics of the contributions paid. The study of existing economic mechanisms to protect against pension risks will provide the

  16. Economic Decision Making: Application of the Theory of Complex Systems

    Science.gov (United States)

    Kitt, Robert

    In this chapter the complex systems are discussed in the context of economic and business policy and decision making. It will be showed and motivated that social systems are typically chaotic, non-linear and/or non-equilibrium and therefore complex systems. It is discussed that the rapid change in global consumer behaviour is underway, that further increases the complexity in business and management. For policy making under complexity, following principles are offered: openness and international competition, tolerance and variety of ideas, self-reliability and low dependence on external help. The chapter contains four applications that build on the theoretical motivation of complexity in social systems. The first application demonstrates that small economies have good prospects to gain from the global processes underway, if they can demonstrate production flexibility, reliable business ethics and good risk management. The second application elaborates on and discusses the opportunities and challenges in decision making under complexity from macro and micro economic perspective. In this environment, the challenges for corporate management are being also permanently changed: the balance between short term noise and long term chaos whose attractor includes customers, shareholders and employees must be found. The emergence of chaos in economic relationships is demonstrated by a simple system of differential equations that relate the stakeholders described above. The chapter concludes with two financial applications: about debt and risk management. The non-equilibrium economic establishment leads to additional problems by using excessive borrowing; unexpected downturns in economy can more easily kill companies. Finally, the demand for quantitative improvements in risk management is postulated. Development of the financial markets has triggered non-linearity to spike in prices of various production articles such as agricultural and other commodities that has added market

    The obesity epidemic has raised considerable public health concerns, but there are few validated longitudinal simulation models examining the human and economic cost of obesity. This paper describes a microsimulation model as a comprehensive tool to understand the relationship between body weight, health, and economic outcomes. Patient health and economic outcomes were simulated annually over 10 years using a Markov-based microsimulation model. The obese population examined is nationally representative of obese adults in the US from the 2005-2012 National Health and Nutrition Examination Surveys, while a matched normal weight population was constructed to have similar demographics as the obese population during the same period. Prediction equations for onset of obesity-related comorbidities, medical expenditures, economic outcomes, mortality, and quality-of-life came from published trials and studies supplemented with original research. Model validation followed International Society for Pharmacoeconomics and Outcomes Research practice guidelines. Among surviving adults, relative to a matched normal weight population, obese adults averaged $3900 higher medical expenditures in the initial year, growing to $4600 higher expenditures in year 10. Obese adults had higher initial prevalence and higher simulated onset of comorbidities as they aged. Over 10 years, excess medical expenditures attributed to obesity averaged $4280 annually-ranging from $2820 for obese category I to $5100 for obese category II, and $8710 for obese category III. Each excess kilogram of weight contributed to $140 higher annual costs, on average, ranging from $136 (obese I) to $152 (obese III). Poor health associated with obesity increased work absenteeism and mortality, and lowered employment probability, personal income, and quality-of-life. This validated model helps illustrate why obese adults have higher medical and indirect costs relative to normal weight adults, and shows that medical costs

    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.

    The pressure on the Earth's environment and resources is the ultimate result of population growth and the only humane means available for stabilizing world population is to increase per capita living standards in the developing countries. However, this will require a very large increase in global energy consumption. If, as at present, the energy demand is met largely by fossil fuels, atmospheric concentrations of CO 2 will rise rapidly. Until the end of the century, and perhaps beyond it, any actions to control CO 2 emissions will be taken for precautionary reasons alone, because no reliable basis will exist for predicting their global (or regional) impact on the climate. The sustainability of the natural environment is also under threat from human activities such as the clearing of forests for crop-growing and grazing. The resulting elimination of habitats for, and genetic variability in, the victor is as serious a concern as global warming. The economic and social consequences of rigidly curtailing the growth of energy use in developed countries would be severe, and in developing countries extreme; even then greenhouse gas build up could only be slowed not prevented. On the other hand, a wealthier world would be more able to bear the financial burden of protecting biodiversity. It is concluded that since the developed countries on whom the main cost would have to fall, adequate effort into both biodiversity and greenhouse gas reduction, biodiversity must take procedence.

    There is a growing volume of literature on health economic evaluation, with this form of analysis becoming increasingly influential at the decision-making level worldwide. The purpose of this study was to review the current state of health economic evaluation in Greece, with a view to uncovering reasons why its use in this country is limited. A search of the NHS Economic Evaluation Database was undertaken. The search included cost, cost-of-illness, cost-minimization, cost-effectiveness, cost-consequences, cost-utility, and cost-benefit analyses and was narrowed only to Greek authors undertaking solo or joint health economic evaluation in Greece. The search revealed that, in Greece, very little health economic evaluation has been undertaken. The main reason for the lack of interest is that the current chaotic healthcare system structure and financing does not provide the appropriate incentives to stimulate a powerful interest in this type of research. This condition is a result of the lack of a long-term national health policy and the hesitation of the present and past Greek governments to date to proceed to large-scale reforms because of political considerations. The Greek governments have also been content with the good health indicators being achieved. Even if it is accepted that good health prevails in Greece, slower economic growth rates, an ageing population, and the continuous immigration will place increasing pressure on healthcare resources and will necessitate a more rational use of these resources. Health economic evaluation, by weighing benefits against costs, therefore, has an important role to play.

    Previous research has found a positive short-term relationship between the 2008 collapse and hypertension in Icelandic males. With Iceland's economy experiencing a phase of economic recovery, an opportunity to pursue a longer-term analysis of the collapse has emerged. Using data from a nationally representative sample, fixed-effect estimations and mediation analyses were performed to explore the relationship between the Icelandic economic collapse in 2008 and the longer-term impact on hypertension and cardiovascular health. A sensitivity analysis was carried out with pooled logit models estimated as well as an alternative dependent variable. Our attrition analysis revealed that results for cardiovascular diseases were affected by attrition, but not results from estimations on the relationship between the economic crisis and hypertension. When compared to the boom year 2007, our results point to an increased probability of Icelandic women having hypertension in the year 2012, when the Icelandic economy had recovered substantially from the economic collapse in 2008. This represents a deviation from pre-crisis trends, thus suggesting a true economic-recovery impact on hypertension.

  4. Energy and economic growth: Grounding our understanding in physical reality

    Ockwell, David G.

    2008-01-01

    This article attempts to summarise the complex, wide ranging and unresolved debate within the economics literature on the possibility of decoupling economic growth from energy use. It explores the difference between neo-classical and ecological economic worldviews and highlights how the ecological economic approach attempts to ground its analysis within the physical limits implied by the laws of thermodynamics. Once these laws are accounted for, the possibility of decoupling economic growth from energy use seems more limited than neo-classical economics implies. Analysis of empirical evidence also demonstrates that observed improvements in GDP/energy use ratios in the USA are better explained by shifts towards higher quality fuels than by improvements in the energy efficiency of technologies. This implies a need to focus on decarbonising energy supply. Furthermore, where energy-efficiency improvements are attempted, they must be considered within the context of a possible rebound effect, which implies that net economy-wide energy savings from energy-efficiency improvements may not be as large as the energy saved directly from the efficiency improvement itself. Both decarbonising energy supply and improving energy efficiency require the rapid development and deployment of new and existing low-carbon technologies. This review therefore concludes by briefly outlining areas of economic thought that have emerged as a result of engagement between economists and experts from other disciplines. They include ecological, evolutionary and institutional economics, all of which can make policy-relevant contributions to achieving a transition to a low-carbon economy

  6. Integrating economic analysis and the science of climate instability

    2006-01-01

    Scientific understanding of climate change and climate instability has undergone a revolution in the past decade with the discovery of numerous past climate transitions so rapid, and so unlike the expectation of smooth climate changes, that they would have previously been unbelievable to the scientific community. Models commonly used by economists to assess the wisdom of adapting to human-induced climate change, rather than averting it, lack the ability to incorporate this new scientific knowledge. Here, we identify and explain the nature of recent scientific advances, and describe the key ways in which failure to reflect new knowledge in economic analysis skews the results of that analysis. This includes the understanding that economic optimization models reliant on convexity are inherently unable to determine an 'optimal' policy solution. It is incumbent on economists to understand and to incorporate the new science in their models, and on climatologists and other scientists to understand the basis of economic models so that they can assist in this essential effort.

    Full Text Available Given the rapid increase in the number and share of the elderly in the total population, good healthand healthy ageing are an important factor in the socio-economic development of ageing societies. Selfperceivedhealth is one of the most important health and well-being indicators. The article presents theresults of research on self-perceived elderly health based on data from "Household Budget Survey" for2006-2015 (NBS. The study reveals a slow increase in life expectancy and healthy life expectancy, as wellas time spent in good health. The life expectancy without chronic illness is lower than healthy lifeexpectancy. There is a positive rise in the self-assessment of the elderly for both sexes and at different agesafter 60 years. The regression analysis of factors influencing self-perceived health (age, sex, education level,welfare level, degree of disability and civil status, demonstrates that among the most important factors withwhich self-responding health is associated, as bad and very bad were highlighted the low level of educationand material welfare, as well as the presence of behavioural vices (smoking.

  8. Population, poverty and economic development.

    2009-10-27

    Economists, demographers and other social scientists have long debated the relationship between demographic change and economic outcomes. In recent years, general agreement has emerged to the effect that improving economic conditions for individuals generally lead to lower birth rates. But, there is much less agreement about the proposition that lower birth rates contribute to economic development and help individuals and families to escape from poverty. The paper examines recent evidence on this aspect of the debate, concludes that the burden of evidence now increasingly supports a positive conclusion, examines recent trends in demographic change and economic development and argues that the countries representing the last development frontier, those of Sub-Saharan Africa, would be well advised to incorporate policies and programmes to reduce high fertility in their economic development strategies.

    Application of municipal residues, e.g. wastewater or sewage sludge, to Short Rotation Coppice (SRC) is among the most attractive methods for attaining environmental and energy goals set for Europe. At current woodchip prices in Sweden, the gross margin for SRC cultivation is positive only if biomass production is >9 t DM/ha yr. The gross profit margin increases (by 39 and 199 EUR/GJ, respectively) if sewage sludge and wastewater are applied to SRC. Application of residues to SRC has proved to be an acceptable alternative treatment method, and the farmer's profit can be markedly increased if compensation is paid for waste treatment. If all available sludge and wastewater were applied to SRC plantations, they could be grown on large agricultural areas in Europe, and c. 6000 PJ of renewable energy could be produced annually. However, a more economical landuse strategy, e.g. the use of more P-rich residues, appears more rational, and is biologically justifiable. (author)

    Economic growth has been the single biggest contributor to population health since the Industrial Revolution. The growth paradigm, by definition, is dynamic, implying similar diminishing returns on investment at both the macro- and the micro-economic levels. Changes in patterns of health in developing countries, from predominantly microbial-related infectious diseases to lifestyle-related chronic diseases (e.g., obesity, type 2 diabetes) beyond a point of economic growth described as the epidemiologic transition, suggest the start of certain declining benefits from further investment in the growth model. These changes are reflected in slowing improvements in some health indices (e.g., mortality, infant mortality) and deterioration in others (e.g., disability-associated life years, obesity, chronic diseases). Adverse environmental consequences, such as climate change from economic development, are also related to disease outcomes through the development of inflammatory processes due to an immune reaction to new environmental and lifestyle-related inducers. Both increases in chronic disease and climate change can be seen as growth problems with a similar economic cause and potential economic and public health-rather than personal health-solutions. Some common approaches for dealing with both are discussed, with a plea for greater involvement by health scientists in the economic and environmental debates in order to deal effectively with issues like obesity and chronic disease.

  13. Economic drivers of mineral supply

    The debate over the adequacy of future supplies of mineral resources continues in light of the growing use of mineral-based materials in the United States. According to the U.S. Geological Survey, the quantity of new materials utilized each year has dramatically increased from 161 million tons2 in 1900 to 3.2 billion tons in 2000. Of all the materials used during the 20th century in the United States, more than half were used in the last 25 years. With the Earth?s endowment of natural resources remaining constant, and increased demand for resources, economic theory states that as depletion approaches, prices rise. This study shows that many economic drivers (conditions that create an economic incentive for producers to act in a particular way) such as the impact of globalization, technological improvements, productivity increases, and efficient materials usage are at work simultaneously to impact minerals markets and supply. As a result of these economic drivers, the historical price trend of mineral prices3 in constant dollars has declined as demand has risen. When price is measured by the cost in human effort, the price trend also has been almost steadily downward. Although the United States economy continues its increasing mineral consumption trend, the supply of minerals has been able to keep pace. This study shows that in general supply has grown faster than demand, causing a declining trend in mineral prices.

    This document examines the claim that legally binding commitments undertaken by Annex I Parties to reduce greenhouse gas (GHG) emissions would result in adverse economic impacts on developing countries. This is examined through the case of the Indian economy. The impact of a range of carbon taxes on trade between India and the US (a major trading partner) is analysed, using a partial, static framework. This study reveals that impacts on India of commitments of Annex I countries to comply with emissions reduction targets 'prima facie' are marginal. However, economies importing capital intensive products from Annex I countries are likely to have adverse second-order impacts. In such a scenario, there is a case for increased south-south trade with increased flows from countries with a large industrial base. Higher costs in Annex I countries will have a two-fold effect on developing economies in the long-term: more rapid evolution of their indigenous industrial base and positive environmental transitions that accompany development.

Results in the short and long term made it clear that there is a difference in the outcome of Applied Studies where we find that each supports a relationship Wagner in the sense that the causal trending of real GDP to government spending and more precisely to increase the economic growth lead to increased aggregate demand which leads in turn increasing the need to increase government spending and to increase the resources available to the government sector to finance the increase in spending by the additional resources resulting from the economic growth while others opines opposes the existence of the relationship.

  18. Understanding the Rapid Reduction of Undernutrition in Nepal, 2001-2011.

    Directory of Open Access Journals (Sweden)

    Derek D Headey

    Full Text Available South Asia has long been synonymous with unusually high rates of undernutrition. In the past decade, however, Nepal has arguably achieved the fastest recorded decline in child stunting in the world and has done so in the midst of civil war and post-conflict political instability. Given recent interest in reducing undernutrition-particularly the role of nutrition-sensitive policies-this paper aims to quantitatively understand this surprising success story by analyzing the 2001, 2006, and 2011 rounds of Nepal's Demographic Health Surveys. To do so, we construct models of the intermediate determinants of child and maternal nutritional change and then decompose predicted changes in nutrition outcomes over time. We identify four broad drivers of change: asset accumulation, health and nutrition interventions, maternal educational gains, and improvements in sanitation. Many of these changes were clearly influenced by policy decisions, including increased public investments in health and education and community-led health and sanitation campaigns. Other factors, such as rapid growth in migration-based remittances, are more a reflection of household responses to changing political and economic circumstances.

    Full Text Available The article deals with the problem of the implementation of economic reforms in the Czech and Slovak Federal Republic, which took place in the aftermath of the Velvet Revolution, from 1990 to 1992. The author examines the positive and negative effects of economic transformation in the Czech Republic and the Slovak Republic. Particular attention is paid to influence of siting of the defense industry in the growth of unemployment in Slovakia. The article also touches upon the issue of privatization process, defined its main elements and stages. It is spoken in detail about illegal machinations, which are primarily engaged in by privatization investment funds. According to the article, Czechoslovakian politicians and economists agreed on a scenario of rapid market reforms, and Czech part of the federation was been better prepare for this step. Much attention is given to the problem of restitution of property that was nationalized in the period of communism. The researcher concludes that the economic transformation have contributed to the collapse of the federal state of Czechs and Slovaks.

    To estimate the economic burden of kidney disorders in Korea. The economic burden of kidney disorders was estimated using a prevalence-based approach. Related kidney diseases in patients with kidney disorders (RPWKD) were defined using codes from the tenth International Classification of Disease (E70-E90, F30-F48, F60-F69, F90-F99, K65-K67, N00-N08, N17-N19, and N30-N39). All diseases in patients with kidney disorders (APWKD) were defined as kidney disorders that involved all disease codes. Economic costs were divided into direct costs (medical costs and non-medical costs) and indirect costs (productivity loss because of morbidity and premature mortality). The prevalence of kidney disorders increased from 0.08% (2008) to 0.11% (2011). The total economic burden of RPWKD also substantially increased from $898.9 million (2008) to $1.43 billion (2011). This ∼59.4% increase in the economic burden was equal to 0.12% of the Korean gross domestic product. The economic burden of APWKD also increased during the study period: $1.06 billion (2008), $1.23 billion (2009), $1.44 billion (2010), and $1.46 billion (2011). The present study provides the first data regarding the economic burden of kidney disorders in Korea. The findings support the need for early intervention services and prevention programs to prevent, identify, and manage kidney disorders.
