    Full Text Available During the financial and economic crisis, the management of an entity must establish a plan and apply strategies needed to mitigate the negative effects due to the action of disturbing factors. Management must have a vision of business evolution, of costumer and supplier perspective, of how to develop the technological equipment in order to increase profitability and product quality. The manager must give utmost importance to all economic information he receives, to analyze it, to group it into categories depending on the effects they can produce, to establish the extent to which it influences the activity. The strategies a manager applies are also based on his flair, culture, knowledge or the human and material resources at its disposal

    Full Text Available Besides the models of M. Keynes, R.F. Harrod, E. Domar, D. Romer, Ramsey-Cass-Koopmans etc., the R.M. Solow model is part of the category which characterizes the economic growth. The paper proposes the study of the R.M. Solow adjusted model of economic growth, while the adjustment consisting in the model adaptation to the Romanian economic characteristics. The article is the first one from a three paper series dedicated to the macroeconomic modelling theme, using the R.M. Solow model, such as: “Measurement of the economic growth and extensions of the R.M. Solow adjusted model” and “Evolution scenarios at the Romanian economy level using the R.M. Solow adjusted model”. The analysis part of the model is based on the study of the equilibrium to the continuous case with some interpretations of the discreet one, by using the state diagram. The optimization problem at the economic level is also used; it is built up of a specified number of representative consumers and firms in order to reveal the interaction between these elements.

  11. Leg-adjustment strategies for stable running in three dimensions

    International Nuclear Information System (INIS)

    Peuker, Frank; Maufroy, Christophe; Seyfarth, André

    2012-01-01

    The dynamics of the center of mass (CoM) in the sagittal plane in humans and animals during running is well described by the spring-loaded inverted pendulum (SLIP). With appropriate parameters, SLIP running patterns are stable, and these models can recover from perturbations without the need for corrective strategies, such as the application of additional forces. Rather, it is sufficient to adjust the leg to a fixed angle relative to the ground. In this work, we consider the extension of the SLIP to three dimensions (3D SLIP) and investigate feed-forward strategies for leg adjustment during the flight phase. As in the SLIP model, the leg is placed at a fixed angle. We extend the scope of possible reference axes from only fixed horizontal and vertical axes to include the CoM velocity vector as a movement-related reference, resulting in six leg-adjustment strategies. Only leg-adjustment strategies that include the CoM velocity vector produced stable running and large parameter domains of stability. The ability of the model to recover from perturbations along the direction of motion (directional stability) depended on the strategy for lateral leg adjustment. Specifically, asymptotic and neutral directional stability was observed for strategies based on the global reference axis and the velocity vector, respectively. Additional features of velocity-based leg adjustment are running at arbitrary low speed (kinetic energy) and the emergence of large domains of stable 3D running that are smoothly transferred to 2D SLIP stability and even to 1D SLIP hopping. One of the additional leg-adjustment strategies represented a large convex region of parameters where stable and robust hopping and running patterns exist. Therefore, this strategy is a promising candidate for implementation into engineering applications, such as robots, for instance. In a preliminary comparison, the model predictions were in good agreement with the experimental data, suggesting that the 3D SLIP is an

    Full Text Available • The flexicurity concept – a combination of flexibility and security strategies, specific to each country – is a successful outcome[1] of the 2010 Lisbon Strategy. Ever since 2000, this concept has been implemented for continuing the European labour markets reform. The conclusion of the Mission for Flexicurity[2] is that the European labour markets challenges have not changed, therefore flexicurity is the strategy to be further implemented in order to align to the new competition requirements, providing also the necessary social protection, especially on the current economic crisis background.   The paper addresses the flexicurity concept development, the implications of the flexicurity strategies and of the steps taken on the European Union Member States labour markets, on the economic crisis background.

    We study the inferences about labor adjustment costs obtained by the 'gap methodology' of Caballero and Engel [1993] and Caballero, Engel and Haltiwanger [1997]. In that approach, the policy function of a manufacturing plant is assumed to depend on the gap between a target and the current level of employment. Using time series observations, these studies reject the quadratic cost of adjustment model and find that aggregate employment dynamics depend on the cross sectional distribution of empl...

    Soutschek, Alexander; Schubert, Torsten

    2014-10-01

    Decision making in the Ultimatum game requires the resolution of conflicts between economic self-interest and fairness intuitions. Since cognitive control processes play an important role in conflict resolution, the present study examined how control processes that are triggered by conflicts between fairness and self-interest in unfair offers affect subsequent decisions in the Ultimatum game. Our results revealed that more unfair offers were accepted following previously unfair, compared to previously fair offers. Interestingly, the magnitude of this conflict adaptation effect correlated with the individual subjects' focus on economic self-interest. We concluded that conflicts between fairness and self-interest trigger cognitive control processes, which reinforce the focus on the current task goal. Copyright © 2014 Elsevier B.V.

  7. Strategies for environmentally sound economic development

    International Nuclear Information System (INIS)

    Duchin, F.; Lange, G.M.

    1991-01-01

    This paper reports that it has been estimated that the burning of fossil fuels and the clearing of forests account for 6-7 billion tons of carbon emissions each year. Combustion also results in significant emissions of sulfur oxides and nitrogen oxides. While the growth in the use of fuels has slowed considerably in the developed regions of North America, western Europe, and Japan over the past decade, pressure for increased energy use and the clearing of forests can be expected with even moderate economic and population growth in the developing regions of Asia, Africa, and Latin America. Researchers at the Institute for Economic Analysis have begun the formulation and analysis of alternative scenarios describing environmentally sound economic development over the next 50 years. These scenarios include activities aimed at improving the standards of living in developing countries while reducing emissions of the aforementioned gases or removing carbon from the atmosphere. Specific alternatives include tropical forestation; the adoption of relatively clean and efficient boilers, especially for the production of electricity in developing countries, as well as greater use of cogeneration systems and hydroelectricity; alternative transportation strategies; and conservation of energy in households of rich and middle-income countries (e.g., efficient lighting fixtures, appliances, and cooling equipment)

    2016-10-01

    Full Text Available The article is devoted to the transformation of the energy strategy of Russia in the conditions of the current economic crisis. The special attention is paid to current trends in the sphere of international relations having a decisive influence on the formation of Russia’s energy strategy. The authors point to the crisis of the modern world, the deepening of interstate contradictions, the expansion of confrontation, the revision of the uniform principles of trade, established by the World Trade Organization, the changes in the global financial system. The authors investigate the possibility of political arrangements between the leading suppliers of oil on the destabilization of the oil market in order to achieve geopolitical goals. In the article special attention is also paid to the issue of political motivation of anti-Russian sanctions directed at impeding Russia’s development and its Fuel & Energy Complex, in particular. Today, against the background of the current political situation, the energy strategy of Russia is exposed to adjustment. The country has the important task of ensuring technological independence of the energy sector on the basis of import substitution of the equipment, diversification of the directions of export of energy resources, preservation of leading positions in the world market of peaceful nuclear energy, etc. The authors conclude that the energy strategy of Russia is important part of foreign policy strategy of the country, and it is focused on practical cooperation with all countries and is aimed at protecting interests of the state.

    Huq-hussain, S

    1995-10-01

    Data from a field survey of slum and squatter settlements in Dhaka, Bangladesh, are used to examine the social adjustment of poor, female migrants to work, occupational choice, work satisfaction, income, control over income, and women's role in the family economy. A "poor household," defined in terms of nutritional intake, included those families receiving under 2122 cal/person/day. 44% of the urban population in Bangladesh do not obtain the daily nutritional requirement. Findings indicate that 61% of all female migrants expected to find work on arrival in the city. 44% of female migrants were willing to take any kind of work available at the time of arrival. Over 66% of all females found work in less than 6 months. Almost 25% took 6 months to a year to find a job, and 15% found work after a year's time. Recent migrants, who were older, found work quicker. 16% of female migrants found their job with help from relatives and friends (23% of recent migrants and 14% of long-term migrants). Among female migrants who sought a job on their own, 14% found work within 6 months. 3% found work between 6 months and a year. The rest were engaged in family and home-based work or found a job much later. In Dhaka, most women migrants worked in the service or informal sector. 40% of the sample worked as domestics, 38% worked in the informal sector, 16% worked in other informal work, and 5% worked in export-based garment industries. Most female migrants lived in the British Dhaka zone and the post-British Dhaka zone. Those living in the Mughal Dhaka zone tended to work in home-based informal activities. Garment industry workers tended to have more education. Women in the informal sector did not receive cash income. Just over 33% received income in kind, about 25% received a low income, and another 25% received a moderate income. In 71% of cases, husbands or fathers handled the money. 29% handled income on their own. Their own earnings went mostly for survival needs. Over 70% changed

    The study's purpose was to explore whether frequency of cyberbullying victimization, cognitive appraisals, and coping strategies were associated with psychological adjustments among college student cyberbullying victims. A convenience sample of 121 students completed questionnaires. Linear regression analyses found frequency of cyberbullying victimization, cognitive appraisals, and coping strategies respectively explained 30%, 30%, and 27% of the variance in depression, anxiety, and self-esteem. Frequency of cyberbullying victimization and approach and avoidance coping strategies were associated with psychological adjustments, with avoidance coping strategies being associated with all three psychological adjustments. Interventions should focus on teaching cyberbullying victims to not use avoidance coping strategies. Copyright © 2015 Elsevier Inc. All rights reserved.

    Joilson Dias

    2015-01-01

    Full Text Available The objective of this paper is to learn about the effects of the adjustment costs, economic growth, imports and exports on human capital labor demand. The dynamic model proposed by Sargent (1978 was adjusted to consider three types of human capital: (a one with fundamental education (1–8 years of schooling; (b one with secondary education level (9–11 years of education; (c and one with tertiary education level (12 years or more of schooling. Using state level panel data, the dynamic econometrics estimates showed the following results: (i the labor market adjustment costs are very higher; (ii the adjustment cost for the human capital with intermediary education level is the highest one compared to the others; (iii the states’ economic growth favor those with superior education; (iv the imports seems to favor the demand for those with intermediate education levels; (v the degree of openness does show some weak effect on the demand for human capitals with intermediate education. In sum, the growing demand for human capital with some superior education seems to be more associated to its lower adjustment cost and economic growth; the non-significance of real wage elasticity and high adjustment cost seems to indicate that the human capital with intermediate knowledge is in short supply; hence, economic education policy that increases supply of such human capital are in need.

    International Nuclear Information System (INIS)

    Motta, R.S. da; Rocha Ferreira, L. da

    1987-01-01

    The aim of this paper is to discuss the economic impact on the Brazilian National Alcohol Programme caused by changes in the energy scenery, in view of recent oil price fall in the international market, and evaluate the necessary adjustments of the Programme according to the new Brazilian economic reality. The economic analysis concludes that the alcohol production, considering current production capacity and its investments, could be economically feasible at international oil prices near US$ 30.00. Excluding investments, its feasibility would be between US$ 18.00 and US$ 20.00 per equivalent oil barrel. Based on these conclusions, proposals for adjusting the PROALCOOL are discussed, including alternative pricing, fiscal and credit policies to control the alcohol-fuel demand. (author)

  16. POLICY IMPLICATIONS OF ADJUSTING RANDOMIZED TRIAL DATA FOR ECONOMIC EVALUATIONS: A DEMONSTRATION FROM THE ASCUS-LSIL TRIAGE STUDY

    Science.gov (United States)

    Campos, Nicole G.; Castle, Philip E.; Schiffman, Mark; Kim, Jane J.

    2013-01-01

    Background Although the randomized controlled trial (RCT) is widely considered the most reliable method for evaluation of health care interventions, challenges to both internal and external validity exist. Thus, the efficacy of an intervention in a trial setting does not necessarily represent the real-world performance that decision makers seek to inform comparative effectiveness studies and economic evaluations. Methods Using data from the ASCUS-LSIL Triage Study (ALTS), we performed a simplified economic evaluation of age-based management strategies to detect cervical intraepithelial neoplasia grade 3 (CIN3) among women who were referred to the study with low-grade squamous intraepithelial lesions (LSIL). We used data from the trial itself to adjust for 1) potential lead time bias and random error that led to variation in the observed prevalence of CIN3 by study arm, and 2) potential ascertainment bias among providers in the most aggressive management arm. Results We found that using unadjusted RCT data may result in counterintuitive cost-effectiveness results when random error and/or bias are present. Following adjustment, the rank order of management strategies changed for two of the three age groups we considered. Conclusion Decision analysts need to examine study design, available trial data and cost-effectiveness results closely in order to detect evidence of potential bias. Adjustment for random error and bias in RCTs may yield different policy conclusions relative to unadjusted trial data. PMID:22147881

    Directory of Open Access Journals (Sweden)

    Roxana Maria Grecu

    2011-06-01

    Full Text Available The strategies for structural-systemic crisis management have generated, to a geographical level, a number of differences between EU countries. These cleavages are the result of differentialmacroeconomic policies. In this context, this article has the aim of achieving a comparative approach between countries of the south, west and east of the EU space. Also our approach is focused on observing the nature of macroeconomic policies and also on identifying a "pattern" associated with a common ideal -type of "rational choice" in the efficient and effective management of systemic crises. This article aims to identify areas of growth and economic stability of a particular model of public policy and political-economic ideology, to set up a mechanism for "economic engineering”. From the methodological point of view, this article uses a quantitativemethodology, derived from mathematical analysis, statistics and stochastic, in order to explain, understand and predict the possible evolution of the systemic crises in the EU countries. The interest lies in the possibility of giving a model of macroeconomic policy for the adjustment of inflationist imbalances, labor market and pricepolicy, and also in regulating the equation of production-consumption.

  11. Optimal Portfolio Strategy under Rolling Economic Maximum Drawdown Constraints

    Directory of Open Access Journals (Sweden)

    Xiaojian Yu

    2014-01-01

    Full Text Available This paper deals with the problem of optimal portfolio strategy under the constraints of rolling economic maximum drawdown. A more practical strategy is developed by using rolling Sharpe ratio in computing the allocation proportion in contrast to existing models. Besides, another novel strategy named “REDP strategy” is further proposed, which replaces the rolling economic drawdown of the portfolio with the rolling economic drawdown of the risky asset. The simulation tests prove that REDP strategy can ensure the portfolio to satisfy the drawdown constraint and outperforms other strategies significantly. An empirical comparison research on the performances of different strategies is carried out by using the 23-year monthly data of SPTR, DJUBS, and 3-month T-bill. The investment cases of single risky asset and two risky assets are both studied in this paper. Empirical results indicate that the REDP strategy successfully controls the maximum drawdown within the given limit and performs best in both return and risk.

    Okanli, Ayse; Tanriverdi, Derya; Ipek Coban, Gülay; Asi Karakaş, Sibel

    Multiple sclerosis (MS) is a disease with significant psychosocial adjustment challenges. The objective of the study was to assess the psychosocial adjustment and coping strategies in patients with MS and to put forth the relationships between them. The sample group comprised 85 outpatients with MS who were admitted to the Neurology Clinic of a university hospital for treatment between October 2007 and July 2008. Data were acquired via an information form and the Psychosocial Adjustment to Illness Scale and Coping Strategy Indicator. It was determined that 55% of the patients had poor psychosocial adjustment levels. Statistically significant relationship was found between Psychosocial Adjustment to Illness Scale-Self-Report and problem solving as well as seeking social support coping strategies ( p Psychosocial adjustment got worse with decreasing problem-solving and seeking-social support coping strategies of patients. The psychosocial adjustment to MS of patients is closely related with effective coping strategies. The results have emphasized the significant role of mental health and social services and coping strategies regarding the comprehensive care needs of these patients.

    1984-01-01

    A recently concluded EPRI study has generated much of the information needed by utilities when they consider the purchase of volume reduction equipment. This paper presents some of the study's results on volume reduction economics. The paper contains two types of results. The first is a detailed look at the economics of fourteen equipment options at a hypothetical reactor station. Costs were calculated with VRTECH, a radwaste economics computer program developed by TASC. This analysis illustrates the major points of the project conclusions. Second, the effects of the major assumptions used in the hypothetical case are examined. This analysis shows that the radwaste generation rate and the burial cost escalation rate are primary considerations when evaluating the benefit of each option

    Kraemer, Lia M.; Stanton, Annette L.; Meyerowitz, Beth E.; Rowland, Julia H.; Ganz, Patricia A.

    2011-01-01

    This study’s goals were to examine coping strategies of women and their male partners as predictors of change in women’s adjustment over the year following breast cancer treatment and to test whether partners’ coping processes interact to predict adjustment. In a sample of women who had recently completed breast cancer treatment and were taking part in a psychoeducational intervention trial and their partners, patients’ and partners’ cancer-specific coping strategies were assessed at study entry (average of 10 months after diagnosis). Assessed at study entry and 20 months after diagnosis (n = 139 couples), dependent variables were women’s general (i.e., vitality, depressive symptoms, relationship satisfaction) and cancer-specific adjustment (i.e., cancer-specific distress, perceived benefits). Both patients’ and partners’ coping strategies at study entry predicted change in women’s adjustment at 20 months. Women’s use of approach-oriented coping strategies predicted improvement in their vitality and depressive symptoms, men’s use of avoidant coping predicted declining marital satisfaction for wives, and men’s approach-oriented strategies predicted an increase in women’s perception of cancer-related benefits. Patients’ and partners’ coping strategies also interacted to predict adjustment, such that congruent coping strategy use generally predicted better adaptation than did dissimilar coping. Findings highlight the utility of examining patients’ and partners’ coping strategies simultaneously. PMID:21928887

    This longitudinal study examines the relationship between parenting behavior and adolescent adjustment (psychological well-being, substance abuse and delinquent behavior) in Chinese adolescents with economic disadvantage (N = 199). Results showed that parenting characteristics were concurrently and longitudinally related to measures of adolescent adjustment, particularly adolescent problem behavior. Compared with the norm based on adolescents of a community sample, poor adolescents perceived parenting characteristics to be more negative and they had relatively lower life satisfaction. Paternal parenting was perceived to be more negative than maternal parenting and parenting behavior was perceived to deteriorate over time.

  1. Inertial fusion: strategy and economic potential

    International Nuclear Information System (INIS)

    Nuckolls, J.H.

    1983-01-01

    Inertial fusion must demonstrate that the high target gains required for practical fusion energy can be achieved with driver energies not larger than a few megajoules. Before a multi-megajoule scale driver is constructed, inertial fusion must provide convincing experimental evidence that the required high target gains are feasible. This will be the principal objective of the NOVA laser experiments. Implosions will be conducted with scaled targets which are nearly hydrodynamically equivalent to the high gain target implosions. Experiments which demonstrate high target gains will be conducted in the early nineties when multi-megajoule drivers become available. Efficient drivers will also be demonstrated by this time period. Magnetic fusion may demonstrate high Q at about the same time as inertial fusion demonstrates high gain. Beyond demonstration of high performance fusion, economic considerations will predominate. Fusion energy will achieve full commercial success when it becomes cheaper than fission and coal. Analysis of the ultimate economic potential of inertial fusion suggests its costs may be reduced to half those of fission and coal. Relative cost escalation would increase this advantage. Fusions potential economic advantage derives from two fundamental properties: negligible fuel costs and high quality energy (which makes possible more efficient generation of electricity)

  6. Economic analysis of coal price-electricity price adjustment in China based on the CGE model

    He, Y.X.; Zhang, S.L.; Yang, L.Y.; Wang, Y.J.; Wang, J.

    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.

  11. Strategies for controlling acid rain: economic considerations

    International Nuclear Information System (INIS)

    Forster, B.A.; Crocker, T.D.

    1992-01-01

    There are two competing approaches to reducing pollution such as the acid rain precursors SOsub(2) and NOsub(x). In the command and control approach, pollution control legislation may dictate the technological method by which specified pollution reductions are to be achieved. A key feature of command-and-control regulations is their inflexibility. The alternative approach relies on market mechanisms and incentives to induce firms to reduce pollution voluntarily. Economists generally prefer this approach because it permits flexibility for firms in selecting abatement methods to minimize costs. This chapter deals with qualitative issues in determining and achieving an ''optimal'' pollution level using various taxes, subsidies or quantitative restrictions. Alternative permit schemes for achieving regional pollution control are considered. Statistical studies are discussed which compare the command-and-control approach with the economic incentives approach and show that there are substantial cost differences between them in most cases. Finally, some institutional factors, that may lead to more costly acid rain control schemes being selected, are examined. A list of 61 references is appended. (UK)

  12. Behavioral economics strategies for promoting adherence to sleep interventions.

    2015-10-01

    Cognitive-behavioral treatment for insomnia and continuous positive airway pressure therapy for obstructive sleep apnea are among the most efficacious sleep interventions. Unfortunately, adherence levels are disappointingly low for these interventions. Behavioral economics offers a promising framework for promoting adherence, often through relatively brief and straightforward strategies. The assumptions, goals, and key strategies of behavioral economics will be introduced. These strategies include providing social norms information, changing defaults, using the compromise effect, utilizing commitment devices, and establishing lottery-based systems. Then, this review will highlight specific behavioral economic approaches to promote patient adherence for three major sleep interventions: 1) behavioral treatment for pediatric insomnia, 2) cognitive-behavioral treatment for adult insomnia, and 3) continuous positive airway pressure for obstructive sleep apnea. Next, behavioral economic strategies will be discussed as ways to improve health care provider adherence to clinical practice guidelines regarding appropriate prescribing of hypnotics and ordering sleep-promoting practices for hospitalized inpatients. Finally, possible concerns that readers may have about behavioral economics strategies, including their efficacy, feasibility, and sustainability, will be addressed. Copyright © 2014 Elsevier Ltd.

    Pisanti, Renato; Lombardo, Caterina; Luszczynska, Aleksandra; Poli, Luca; Bennardi, Linda; Giordanengo, Luca; Berloco, Pasquale Bartolomeo; Violani, Cristiano

    2017-10-01

    This study examined the relations between appraisal of transplant-related stressors, coping, and adjustment dimensions following kidney transplantation (KT). Two models were tested: (1) the main effects model proposing that stress appraisal and coping strategies are directly associated with adjustment dimensions; and (2) the moderating model of stress proposing that each coping strategy interacts with stress appraisal. Importantly, there is a lack of research examining the two models simultaneously among recipients of solid organ transplantation. A total of 174 KT recipients completed the questionnaires. Predictors of post-transplant adjustment included appraisal of transplant-related stressors and coping strategies (task-, emotion-, and avoidance-focused). Adjustment dimensions were psychological distress, worries about the transplant, feelings of guilt, fear of disclosure of transplant, adherence, and responsibility for the functioning of the new organ. The main and moderating effects were tested with regression analyses. Appraisal of transplant-related stressors and emotion-oriented coping were related to all adjustment dimensions, except of adherence and responsibility. Task-oriented coping was positively related to responsibility. Avoidance-oriented coping was negatively correlated with adherence. Only 1 out of 18 hypothesized interactive terms was significant, yielding a synergistic interaction between appraisal of transplant-related stressors and emotion-oriented coping on the sense of guilt. The findings have the potential to inform interventions promoting psychosocial adjustment among KT recipients. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available As a large part of South Africa’s economy is based on the mining industry, this research focused on exploring the coping strategies of business leaders in the mining industry during an economic downturn. Using qualitative research within a constructivist-interpretive paradigm, the researchers sought a deeper understanding of how mining leaders cope during an economic downturn. A purposive sample of seven executive mining leaders of different mining houses was interviewed and data was analysed using Atlas.ti. A conceptual framework for understanding coping strategies at the individual, group and organisational levels for business leaders during an economic downturn was developed and is discussed here. This study contributed to theory and practice by focusing on coping responses to specific situations within a specific context instead of on general coping strategies.

    Glick, Gary C; Rose, Amanda J

    2011-07-01

    The proposal that friendships provide a context for the development of social skills is widely accepted. Yet little research exists to support this claim. In the present study, children and adolescents (N = 912) were presented with vignettes in which a friend encountered a social stressor and they could help the friend and vignettes in which they encountered a stressor and could seek help from the friend. Social strategies in response to these vignettes were assessed in the fall and spring of the school year. Different indicators of friendship adjustment had unique effects on youths' strategies in response to helping tasks. Whereas having more friends predicted decreases in avoidant or hostile strategies, having high-quality friendships predicted emotionally engaged strategies that involved talking about the problem. Moreover, whereas having more friends predicted increases in relatively disengaged strategies, like distraction and acting like the problem never happened, having high-quality friendships predicted decreases in these strategies. The present study also tested whether youths' strategies in the fall predicted changes in friendship adjustment by the spring. Only strategies which may be seen as major friendship transgressions (i.e., avoiding or blaming the friend when the friend encounters a problem) predicted changes in friendship over time. Collectively, these results provide important new information on the interplay between social competencies and friendship experiences and suggest that friendships may provide a critical venue for the development of important relationship skills.

These strategies are based on runs with the RAINS model in which environmental targets have been set based on critical loads for sulphur. The analysis shows that economic restructuring and efficiency improvements in Eastern European countries, as well as in Western Europe, may result in significantly lower sulphur abatement costs. Potential assistance to Eastern Europe to guarantee desired environmental standards in Western countries should therefore focus not only on providing emission control devices but also on the success of the economic transition process.

    The present study examines the associations among social support, coping strategies and relocation adjustment outcomes, including community cohesion, residential satisfaction and depressive symptoms, for older persons in Taiwan displaced by Typhoon Morakot. This study enrolled 372 adults aged 60 years or older who were relocated to permanent houses after Typhoon Morakot destroyed their homes on 8 August 2009. A path analysis simultaneously examined the hypothesized links among social support, coping strategies and relocation adjustment outcomes. The relationships between coping strategies and relocation outcomes varied. Problem-focused and support-seeking coping were positively related to perceived community cohesion, whereas emotion-focused coping was associated with a high number of depressive symptoms. Social support was positively related to residential satisfaction. Additionally, social support was also indirectly related to increased community cohesion and residential satisfaction through its positive relationship with support-seeking and problem-focused coping. More interventions should be implemented to enhance support within informal networks and a sense of belonging to the new resident community, thereby promoting more active coping strategies, enhancing the effectiveness of coping efforts and maximizing positive adjustment outcomes.

  6. Evaluating economic costs and benefits of climate resilient livelihood strategies

    2016-01-01

    Full Text Available A major challenge for international development is to assist the poorest regions to achieve development targets while taking climate change into account. Such ‘climate resilient development’ (CRD must identify and implement adaptation strategies for improving livelihoods while also being cost-effective. While the idea that climate resilience and development goals should be compatible is often discussed, empirical evaluations of the economic impacts of actual CRD investments are practically non-existent. This paper outlines a framework to evaluate economic returns to CRD and applies it in two adaptation strategies trialed in Nusa Tenggara Barat Province, eastern Indonesia. The evaluation framework is composed of three models: a household benefit cost model, a diffusion model, and a regional benefit cost model. The models draw upon the impact evaluation, technology diffusion, and risk assessment literatures, respectively. The analyzes are based on expert opinion and locally-derived information, and hence can be applied in data-poor situations typical of developing countries. Our results explore economic costs and benefits at the household and regional scale, and we identify key input variables that greatly influence the economic returns of the strategies. These variables should therefore be a focus of ongoing investment. We also discuss how the framework is more generally applicable, its limitations including challenges in accounting for less tangible social and ecosystem service benefits, potentially leading to the underestimation of impacts, and how the approach should be complemented by qualitative methods.

  7. Economic Impact Assessment of Alternative Climate Policy Strategies

    This paper investigates the world economic implications of climate change policy strategies, especially the evaluation of impacts by an implementation of Clean Development Mechanisms, Joint Implementation and Emissions trading with a world integrated assessment model. Of special interest in this context are the welfare spill over and competitiveness effects that result from diverse climate policy strategies. In particular, this study elaborates and compares multi gas policy strategies and explores the impacts of the inclusion of sinks. Because of the recent decision of an isolated climate policy strategy by the United States of America, we examine the economic impacts of all world regions by a non cooperative and free rider position of the USA. It turns out that Clean Development Mechanisms and Joint Implementation show evidence of improvement in the economic development in the host countries and increase the share of new applied technologies. The decomposition of welfare effects demonstrates that the competitiveness effect including the spill over effects from trade have the strongest importance because of the intense trade relations between countries. Climatic effects have a significant impact within the next 50 years, cause considerable welfare losses to world regions and will intensify if some highly responsible nations like the USA do not reduce their emissions

    In connection with the publication of a clinical practice guideline on the management of low back pain (LBP) in general practice in Denmark, a cluster randomised controlled trial was conducted. In this trial, a multifaceted guideline implementation strategy to improve general practitioners' treatment of patients with LBP was compared with a usual implementation strategy. The aim was to determine whether the multifaceted strategy was cost effective, as compared with the usual implementation strategy. The economic evaluation was conducted as a cost-utility analysis where cost collected from a societal perspective and quality-adjusted life years were used as outcome measures. The analysis was conducted as a within-trial analysis with a 12-month time horizon consistent with the follow-up period of the clinical trial. To adjust for a priori selected covariates, generalised linear models with a gamma family were used to estimate incremental costs and quality-adjusted life years. Furthermore, both deterministic and probabilistic sensitivity analyses were conducted. Results showed that costs associated with primary health care were higher, whereas secondary health care costs were lower for the intervention group when compared with the control group. When adjusting for covariates, the intervention was less costly, and there was no significant difference in effect between the 2 groups. Sensitivity analyses showed that results were sensitive to uncertainty. In conclusion, the multifaceted implementation strategy was cost saving when compared with the usual strategy for implementing LBP clinical practice guidelines in general practice. Furthermore, there was no significant difference in effect, and the estimate was sensitive to uncertainty.

    Each stage of a product's life cycle requires marketing strategy modifications in response to changing demand levels. The purpose of this study was to investigate changes in ambulatory care center (ACC) operational characteristics indicative of product, market, and distribution channel adjustments that could have a competitive impact upon community pharmacy practice. A questionnaire was mailed to a national sample of 325 ACC managers. Evidence of new product feature additions includes increased emphasis on continued care and increased prevalence of prescription drug dispensing. Expansion into new market segments and distribution channels was demonstrated by increased participation in HMO and employer relationships. The observed adjustments in ACC marketing strategies present obvious challenges as well as less obvious opportunities for community pharmacy practice.

    Studies examining economic hardship consistently have linked family economic hardship to adolescent adjustment via parent and family functioning, but limited attention has been given to adolescents' perceptions of these processes. To address this, the authors investigated the intervening effects of adolescents' perceptions of economic hardship and of parent-adolescent warmth and conflict on the associations between parental economic hardship and adolescent adjustment (i.e., depressive symptoms, risky behaviors, and school performance) in a sample of 246 Mexican-origin families. Findings revealed that both mothers' and fathers' reports of economic hardship were positively related to adolescents' reports of economic hardship, which in turn, were negatively related to parent-adolescent warmth and positively related to parent-adolescent conflict with both mothers and fathers. Adolescents' perceptions of economic hardship were indirectly related to (a) depressive symptoms through warmth with mothers and conflict with mothers and fathers, (b) involvement in risky behaviors through conflict with mothers and fathers, and (c) GPA through conflict with fathers. Our findings highlight the importance of adolescents' perceptions of family economic hardship and relationships with mothers and fathers in predicting adolescent adjustment.

  16. Assessment of five control strategies of an adjustable glazing at three different climate zones

    2015-11-01

    Full Text Available The energy demand for operating modern office spaces is often driven by either the annual heating demand, cooling demand or the demand for electrical lighting. The irradiation of the sun directly and indirectly affects the demand of all three. Consequently, the glazing of higher office buildings is often treated with coating that allows a fixed transmittance. Due to changing exterior conditions and interior needs, a fix-transmittance value is a compromise and most often doesn’t provide optimal thermal and visual conditions. The team in the research project named Fluidglass develops a new glazing in which the transmittance of the glazing can be adjusted. This is possible by colouring a fluid, which is circulated in chambers of the glazing. The concentration of the colorant can be infinitely adjusted. In addition, this window allows collecting heat in the exterior fluid and allows the interior fluid chamber to operate as heating panel. This paper presents a first assessment of different control strategies for adjusting the colorant concentration with a simplified model. The assessed control strategies result in considerably different overall energy demands. Certain control strategies have high potential for reducing the energy demand for heating and cooling depending on the locations (Munich 20–30% , Madrid 50–70% , Dubai 50–60%. However, certain control strategies increase the electricity demand for lighting, which needs to be considered in the further development. In general, control strategies that only consider the solar irradiation are less promising strategies in temperate climate than strategies that also take the interior temperature into account. The results of controls that also respect the thermal comfort based on a Predicted Mean Vote (PMV index can achieve low energy demand, presuming that a deviation from the highest level of comfort is acceptable. At this stage of research, none of the studied control strategies shows to be

    In a building project, several subsystems are designed, among them the air conditioning system. Electrical energy consumption profiles show that this subsystem is responsible for 40 to 50% of total consumption in a commercial building. Besides the study of technical aspects that should be considered in order to assure the thermal comfort of the occupants as well the temperature and humidity conditions for an efficient equipment operation, an economical evaluation of this subsystem should be also made. In retrofit projects, the economical aspect is also critical for such projects in order to assure bigger efficiency in an economically attractive way. This paper analyses some strategies that might be adopted in retrofitting an air conditioning system installed in a commercial building with mixed occupation. By mixed we mean that some floors have a typical office occupation profile and other floors are mainly occupied by electronic equipment. This analysis includes both technical and economical evaluation. The proposed solutions performance are compared to the old system, which allows to verify the retrofitting impact in energy consumption reduction and its economical feasibility. (author)

  19. The economics and ethics of aerosol geoengineering strategies

    Anthropogenic greenhouse gas emissions are changing the Earth's climate and impose substantial risks for current and future generations. What are scientifically sound, economically viable, and ethically defendable strategies to manage these climate risks? Ratified international agreements call for a reduction of greenhouse gas emissions to avoid dangerous anthropogenic interference with the climate system. Recent proposals, however, call for a different approach: geoengineering climate by injecting aerosol precursors into the stratosphere. Published economic studies typically neglect the risks of aerosol geoengineering due to (i) a potential failure to sustain the aerosol forcing and (ii) due to potential negative impacts associated with aerosol forcings. Here we use a simple integrated assessment model of climate change to analyze potential economic impacts of aerosol geoengineering strategies over a wide range of uncertain parameters such as climate sensitivity, the economic damages due to climate change, and the economic damages due to aerosol geoengineering forcings. The simplicity of the model provides the advantages of parsimony and transparency, but it also imposes considerable caveats. For example, the analysis is based on a globally aggregated model and is hence silent on intragenerational distribution of costs and benefits. In addition, the analysis neglects the effects of future learning and is based on a simple representation of climate change impacts. We use this integrated assessment model to show three main points. First, substituting aerosol geoengineering for the reduction of greenhouse gas emissions can fail the test of economic efficiency. One key to this finding is that a failure to sustain the aerosol forcing can lead to sizeable and abrupt climatic changes. The monetary damages due to such a discontinuous aerosol geoengineering can dominate the cost-benefit analysis because the monetary damages of climate change are expected to increase with

    Asynchrony between patient and ventilator breaths is associated with increased duration of mechanical ventilation (MV). Neurally Adjusted Ventilatory Assist (NAVA) controls MV through an esophageal reading of diaphragm electrical activity via a nasogastric tube mounted with electrode rings. NAVA has been shown to decrease asynchrony in comparison to pressure support ventilation (PSV). The objective of this study was to conduct a health economic evaluation of NAVA compared with PSV. We developed a model based on an indirect link between improved synchrony with NAVA versus PSV and fewer days spent on MV in synchronous patients. Unit costs for MV were obtained from the Swedish intensive care unit register, and used in the model along with NAVA-specific costs. The importance of each parameter (proportion of asynchronous patients, costs, and average MV duration) for the overall results was evaluated through sensitivity analyses. Base case results showed that 21% of patients ventilated with NAVA were asynchronous versus 52% of patients receiving PSV. This equals an absolute difference of 31% and an average of 1.7 days less on MV and a total cost saving of US$7886 (including NAVA catheter costs). A breakeven analysis suggested that NAVA was cost effective compared with PSV given an absolute difference in the proportion of asynchronous patients greater than 2.5% (49.5% versus 52% asynchronous patients with NAVA and PSV, respectively). The base case results were stable to changes in parameters, such as difference in asynchrony, duration of ventilation and daily intensive care unit costs. This study showed economically favorable results for NAVA versus PSV. Our results show that only a minor decrease in the proportion of asynchronous patients with NAVA is needed for investments to pay off and generate savings. Future studies need to confirm this result by directly relating improved synchrony to the number of days on MV. © The Author(s), 2015.

    Abstract Background: The aim of this study is to determine the most cost-effective strategy for the treatment of primary open-angle glaucoma (POAG) in Brazil, from the payer's perspective (Brazilian Public Health System) in the setting of the Glaucoma Referral Centers. Methods: Study design was a cost-effectiveness analysis of different treatment strategies for POAG. We developed 3 Markov models (one for each glaucoma stage: early, moderate and advanced), using a hypothetical cohort of POAG patients, from the perspective of the Brazilian Public Health System (SUS) and a horizon of the average life expectancy of the Brazilian population. Different strategies were tested according to disease severity. For early glaucoma, we compared observation, laser and medications. For moderate glaucoma, medications, laser and surgery. For advanced glaucoma, medications and surgery. Main outcome measures were ICER (incremental cost-effectiveness ratio), medical direct costs and QALY (quality-adjusted life year). Results: In early glaucoma, both laser and medical treatment were cost-effective (ICERs of initial laser and initial medical treatment over observation only, were R$ 2,811.39/QALY and R$ 3,450.47/QALY). Compared to observation strategy, the two alternatives have provided significant gains in quality of life. In moderate glaucoma population, medical treatment presented the highest costs among treatment strategies. Both laser and surgery were highly cost-effective in this group. For advanced glaucoma, both tested strategies were cost-effective. Starting age had a great impact on results in all studied groups. Initiating glaucoma therapy using laser or surgery were more cost-effective, the younger the patient. Conclusion: All tested treatment strategies for glaucoma provided real gains in quality of life and were cost-effective. However, according to the disease severity, not all strategies provided the same cost-effectiveness profile. Based on our findings, there should be a

    To evaluate the cost-effectiveness of three strategies for the control of taeniasis in a community, in terms of cost per case treated. A study was conducted in South India to determine the prevalence of taeniasis by screening stool samples from 653 randomly chosen subjects, for coproantigens. The costs incurred in the project were used to estimate the cost per case screened and treated. A one-way sensitivity analysis was carried out for varying rates of taeniasis, different screening strategies and mass therapy. Further sensitivity analysis was carried out with different manpower and test costs. The rate of taeniasis as detected by ELISA for coproantigen was 3 per 1000 (2 of 653 samples). Our study showed that mass therapy without screening for taeniasis would be the most economical strategy in terms of cost per case treated if field workers are employed exclusively for either mass therapy or screening. For each strategy, costs per case treated are higher at low prevalence of taeniasis, with a sharp rise below 15%. In places that are endemic for taeniasis and neurocysticercosis, mass therapy or screening for taeniasis should be considered. Screening by stool microscopy is not cost-effective in terms of cost per case of taeniasis treated owing to its low sensitivity. Although the cost per case of taeniasis treated is high at low prevalence of taeniasis for all options, incorporating mass therapy into existing mass drug distribution programmes might prove to be the most cost-effective control strategy. © 2011 Blackwell Publishing Ltd.

    In this paper, minimum entropy algorithm for controlling chaos, is applied to a Cournot duopoly with different constant marginal costs, as a discrete-time dynamical system which shows chaotic behavior. The ME control is implemented through delayed feedback. It is assumed that the equations of the dynamical system are not known, so the feedback gain cannot be obtained analytically from the system equations. In the ME method the feedback gain is obtained adaptively in such a way that the entropy of the system converges to zero, hence a fixed point of the system will be stabilized. Application of the proposed method with different economic control strategies is numerically investigated. Simulation results show the effectiveness of the ME method for controlling chaos in economic systems with unknown equations.

    2013-01-01

    Social impact mitigation strategies are implemented by the proponents of policies and projects with the intent of reducing the negative, and increasing the positive social impacts of their activities, and facilitating the achievement of policy/project goals. Evaluation of mitigation strategies is critical to improving their future success and cost-effectiveness. This paper evaluates two Forest Industry Structural Adjustment Packages (FISAP) implemented in Australia in the 1990s to 2000s as part of broader policy changes that reduced access to timber from publicly owned native forests. It assesses the effectiveness of the structure, design, implementation and monitoring of the FISAPs, and highlights the interactions between these four elements and their influence on social impacts. The two FISAPs were found to be effective in terms of reducing negative impacts, encouraging positive impacts and contributing towards policy goals, although they did not mitigate negative impacts in all cases, and sometimes interacted with external factors and additional policy changes to contribute to significant short and long term negative impacts. -- Highlights: ► Mitigation strategies aim to reduce negative and enhance positive social impacts ► Mitigation strategy design, implementation, and monitoring are critical to success ► Effective mitigation enhanced the capacity of recipients to respond to change ► Mitigation strategies influenced multiple interacting positive and negative impacts ► Success required good communication, transparency, support, resources and timing

  5. Economic analysis of pandemic influenza vaccination strategies in Singapore.

    Vernon J Lee

    Full Text Available BACKGROUND: All influenza pandemic plans advocate pandemic vaccination. However, few studies have evaluated the cost-effectiveness of different vaccination strategies. This paper compares the economic outcomes of vaccination compared with treatment with antiviral agents alone, in Singapore. METHODOLOGY: We analyzed the economic outcomes of pandemic vaccination (immediate vaccination and vaccine stockpiling compared with treatment-only in Singapore using a decision-based model to perform cost-benefit and cost-effectiveness analyses. We also explored the annual insurance premium (willingness to pay depending on the perceived risk of the next pandemic occurring. PRINCIPAL FINDINGS: The treatment-only strategy resulted in 690 deaths, 13,950 hospitalization days, and economic cost of USD$497 million. For immediate vaccination, at vaccine effectiveness of >55%, vaccination was cost-beneficial over treatment-only. Vaccine stockpiling is not cost-effective in most scenarios even with 100% vaccine effectiveness. The annual insurance premium was highest with immediate vaccination, and was lower with increased duration to the next pandemic. The premium was also higher with higher vaccine effectiveness, attack rates, and case-fatality rates. Stockpiling with case-fatality rates of 0.4-0.6% would be cost-beneficial if vaccine effectiveness was >80%; while at case-fatality of >5% stockpiling would be cost-beneficial even if vaccine effectiveness was 20%. High-risk sub-groups warrant higher premiums than low-risk sub-groups. CONCLUSIONS: The actual pandemic vaccine effectiveness and lead time is unknown. Vaccine strategy should be based on perception of severity. Immediate vaccination is most cost-effective, but requires vaccines to be available when required. Vaccine stockpiling as insurance against worst-case scenarios is also cost-effective. Research and development is therefore critical to develop and stockpile cheap, readily available effective vaccines.

  6. Breeds of risk-adjusted fundamentalist strategies in an order-driven market

    LiCalzi, Marco; Pellizzari, Paolo

    2006-01-01

    This paper studies an order-driven stock market where agents have heterogeneous estimates of the fundamental value of the risky asset. The agents are budget-constrained and follow a value-based trading strategy which buys or sells depending on whether the price of the asset is below or above its risk-adjusted fundamental value. This environment generates returns that are remarkably leptokurtic and fat-tailed. By extending the study over a grid of different parameters for the fundamentalist trading strategy, we exhibit the existence of monotone relationships between the bid-ask spread demanded by the agents and several statistics of the returns. We conjecture that this effect, coupled with positive dependence of the risk premium on the volatility, generates positive feedbacks that might explain volatility bursts.

    2018-05-01

    Full Text Available Wireless charging system for electric vehicles is a hot research issue in the world today. Since the existing research on wireless charging is mostly forward-looking aimed at low-power appliances like household appliances, while electric vehicles need a high-power, high-efficiency, and strong coupling wireless charging system. In this paper, we have specifically designed a 6.6 KW wireless charging system for electric vehicles and have proposed a control strategy suitable for electric vehicles according to its power charging characteristics and existing common wired charging protocol. Firstly, the influence of the equivalent load and frequency bifurcation on a wireless charging system is analyzed in this paper. Secondly, an adaptive load control strategy matching the characteristics of the battery, and the charging pile is put forward to meet the constant current and constant voltage charging requirements to improve the system efficiency. In addition, the frequency adjustment control strategy is designed to realize the real-time dynamic optimization of the entire system. It utilizes the improved methods of rapid judgment, variable step length matching and frequency splitting recognition, which are not adopted in early related researches. Finally, the results of 6.6 kW test show that the control strategy works perfectly since system response time can be reduced to less than 1 s, and the overall efficiency of the wireless charging system and the grid power supply module can reach up to 91%.

    The purpose of this study was to establish a hospital supply chain management (HSCM) model in which three kinds of drugs in the same class and with the same indications were used in creating an optimal robust design and adjustable ordering strategies to deal with a drug shortage. The main assumption was that although each doctor has his/her own prescription pattern, when there is a shortage of a particular drug, the doctor may choose a similar drug with the same indications as a replacement. Four steps were used to construct and analyze the HSCM model. The computation technology used included a simulation, a neural network (NN), and a genetic algorithm (GA). The mathematical methods of the simulation and the NN were used to construct a relationship between the factor levels and performance, while the GA was used to obtain the optimal combination of factor levels from the NN. A sensitivity analysis was also used to assess the change in the optimal factor levels. Adjustable ordering strategies were also developed to prevent drug shortages.

  10. Macrofinancial Indicators in the Economic Strategy of the State

    Full Text Available The aim of the article is to study the effectiveness of the set strategic objectives of the state and the fact of their implementation. On the basis of the analysis and systematization of the existing practical and theoretical framework the place and the importance of macrofinancial indicators in the public finance management system has been determined. The definition of MFI in the broad and narrow sense is suggested. In the broad sense it is a quantitative measure assessing the condition of public finances at the moment of decision-making and reflecting the results of its impact on achieving the objectives of the state financial policy. The narrow sense reduces it to understanding the indicator as the one adapted for the purposes of specific analysis. The experience of previous strategies of the administrative apparatus is studied. On the basis of analyzing the priority macrofinancial indicators the assessment of current practices of implementing the state economic strategy has been carried out. The study found a discrepancy between the objectives set by the Strategy for Sustainable Development “Ukraine – 2020” with the real situation in the country’s economy. It is noted that the use of macrofinancial indicators aimed at achieving a particular limit only within a single reporting period negatively affects the system character of management.

    This publication briefly reports the use of the Three-ME model (Multi-sector Macroeconomic Model for the Evaluation of Environmental and Energy) to assess the combined effect of the several instruments mobilised for the transition towards a low carbon economy within the French National Low Carbon Strategy (SNBC). It first presents the Three-ME model which has been developed since 2008 by the OFCE and the Ademe, is a neo-Keynesian and hybrid model, and which comprises 14.000 equations and 70.000 parameters dealing with prices, interest rates, investments, salaries, foreign trade, State policy, a production function, and a consumption function. Some characteristics of the SNBC scenario are indicated, as well as those of a reference trend-based scenario. Obtained results are then briefly commented in terms of positive ecological and economic impacts of a carbon tax and of sector-based measures defined within the SNBC

    1997-02-01

    Applicability of the MSHIM control strategy, which has been developed by Westinghouse and characterized by elimination of the adjustment to the boron concentration during load maneuvering, to 1300MWe KNGR Cycle-1 is examined by simulation based on one-dimensional transient analyses code, ONED94, under the conditions of relatively large xenon worth and high amplitude of xenon oscillation. CASMO-3/MASTER code system is used to generate the ONED94 model. A processing code, which is referred to as MAS2ONED, is also developed to transform the MASTER calculation results to ONED94 cross section library. The three types of power maneuvering, daily maneuvering, extended weekend load follow, and spinning reserve capacity are simulated to evaluate the capability of the selected load follow technology, by using ONED94 code. By showing that the calculated total peaking factor is maintained below safety limit, it is proved that load follow operation without boron adjustment is feasible with simple control rod motion only. It is expected that the results of this study, such as control rod parameters could give a contribution to the development of load following technology in our country. The developed process code could be utilized in the another simulation of power maneuver in the future

    We modeled the effects of harsh environments in childhood on adjustment in early emerging adulthood, through parenting style and the development of fast Life History Strategies (LHS; risky beliefs and behaviors) in adolescence. Participants were from the Oregon Youth Substance Use Project (N = 988; 85.7% White). Five cohorts of children in Grades 1-5 at recruitment were assessed through one-year post high school. Greater environmental harshness (neighborhood quality and family poverty) in Grades 1-6 predicted less parental investment at Grade 8. This parenting style was related to the development of fast LHS (favorable beliefs about substance users and willingness to use substances at Grade 9, and engagement in substance use and risky sexual behavior assessed across Grades 10-12). The indirect path from harsh environment through parenting and LHS to (less) psychological adjustment (indicated by lower life satisfaction, self-rated health, trait sociability, and higher depression) was significant (indirect effect -.024, p = .011, 95% CI = -.043, -.006.). This chain of development was comparable to that found by Gibbons et al. (2012) for an African-American sample that, unlike the present study, included perceived racial discrimination in the assessment of harsh environment.

    Social relations around the handicapped are generally presented in terms of economic dependence and social inadaptation. This point of view leads to give greater importance, especially in Africa, to studying the way in which group and society help the physically or mentally ill. Actually, this approach does not give a complete account about the real situation of the handicapped in social relations of production and reproduction. From a series of in-depth interviews conducted in handicapped families of the suburbs of Dakar, two aspects are analyzed: the economic role of the handicapped, through the circulation of the product of his begging in his household or through the exploitation of his work as apprentice in a workshop; and his value on the marriage market, where invalid persons are given without dowry if they are women, and must pay a much more important amount if they are men. The social situation of the handicapped thus is not only a matter of assistance or charity, but as well of strategies that the handicapped and above all his circle implement in order to take advantage of the stigma or on the contrary try to erase it.

  17. Alternative energy supply strategies for Pakistan and their economic implications

    1984-01-01

    Pakistan is beset with serious energy supply difficulties arising from a fast growing demand for commercial energy, a poor energy resource base and the high cost of imported energy. The commercial energy requirements are expected to rise from 22.4 million tonnes of coal equivalent (tce) in 1980 to 80 million tce by the year 2000 and to about 200 million tce by 2020, while the country's proven fossil-fuel reserves are only 440 million tce and cannot cope with the demand for long. Pakistan is already dependent on imported energy for 90% of its oil requirements or 30% of the total commercial energy, and is spending 5.5% of its gross domestic product (GDP) on energy imports. The paper analyses the economic implications of a few alternative energy supply strategies. These strategies correspond to two different rates of petroleum exploration and development activity, a high and a low average size of new petroleum finds, and the large-scale use of nuclear power starting in 1990 or after the year 2000. It is found that in the most favourable case (high level of petroleum drilling activity with a high success rate and nuclear power use starting in 1990) Pakistan would be able to achieve self-sufficiency in oil by 2010 and in the total energy supply shortly after 2020. The energy sector's investment requirement will, however, increase gradually from 3% of GDP now to almost 6% of GDP by 2020. (author)

    2017-06-01

    Parasitoid fitness depends on its ability to manipulate reproductive strategies when in competition. This study investigated the parasitism and sex allocation strategies of the parasitic wasp Diaeretiella rapae McIntosh at a range of host (Brevicoryne brassicae L.) and conspecific densities. The results suggest that D. rapae females adjust their progeny production and progeny sex ratio with changing competition. When foraging alone, female D. rapae parasitize larger number of B. brassicae nymphs when the number of available hosts is increased, but the overall proportion of parasitized hosts decreases with increase in host density. The proportion of female offspring also decreases with elevated host density. Increase in the number of female D. rapae foraging together increased total parasitism, but reduced relative contribution of each individual female. The number of female progeny decreased when multiple females competed for the same host. However, foraging experience in the presence of one or more conspecifics increased the parasitism rate and proportion of female progeny. Competing females were more active during oviposition and had shorter lives. The study suggests that both host and foundress (female parasitoid) densities have significant effect on progeny production, sex allocation, and longevity of foraging females. © The Authors 2017.

    2018-05-01

    Intensity saturation can cause decorrelation phenomenon and decrease the measurement accuracy in digital image correlation (DIC). In the paper, the grey intensity adjustment strategy is proposed to improve the measurement accuracy of DIC considering the effect of intensity saturation. First, the grey intensity adjustment strategy is described in detail, which can recover the truncated grey intensities of the saturated pixels and reduce the decorrelation phenomenon. The simulated speckle patterns are then employed to demonstrate the efficacy of the proposed strategy, which indicates that the displacement accuracy can be improved by about 40% by the proposed strategy. Finally, the true experimental image is used to show the feasibility of the proposed strategy, which indicates that the displacement accuracy can be increased by about 10% by the proposed strategy.

    2016-10-01

    Full Text Available Coastal cities in China are challenged by multiple growth paths and strategies related to demands in the housing market, economic growth and eco-system protection. This paper examines the effects of conflicting strategies between economic growth and environmental protection on future urban scenarios in Ningbo, China, through logistic-regression-based cellular automata (termed LogCA modeling. The LogCA model is calibrated based on the observed urban patterns in 1990 and 2015, and applied to simulate four future scenarios in 2040, including (a the Norm-scenario, a baseline scenario that maintains the 1990–2015 growth rate; (b the GDP-scenario, a GDP-oriented growth scenario emphasizing the development in city centers and along economic corridors; (c the Slow-scenario, a slow-growth scenario considering the potential downward trend of the housing market in China; and (d the Eco-scenario, a slow-growth scenario emphasizing natural conservation and ecosystem protections. The CA parameters of the Norm- and Slow-scenarios are the same as the calibrated parameters, while the parameters of proximities to economic corridors and natural scenery sites were increased by a factor of 3 for the GDP- and Eco-scenarios, respectively. The Norm- and GDP-scenarios predicted 1950 km2 of new growth for the next 25 years, the Slow-scenario predicted 650 km2, and the Eco-scenario predicted less growth than the Slow-scenario. The locations where the newly built-up area will emerge are significantly different under the four scenarios and the Slow- and Eco-scenarios are preferable to achieve long-term sustainability. The scenarios are not only helpful for exploring sustainable urban development options in China, but also serve as a reference for adjusting the urban planning and land policies.

  4. Economic Analysis of Immunization Strategies for PRRS Control [corrected].

    Directory of Open Access Journals (Sweden)

    Daniel C L Linhares

    Full Text Available Porcine reproductive and respiratory syndrome virus (PRRSv is a swine-specific pathogen that causes significant increases in production costs. When a breeding herd becomes infected, in an attempt to hasten control and elimination of PRRSv, some veterinarians have adopted a strategy called load-close-expose which consists of interrupting replacement pig introductions into the herd for several weeks (herd closure and exposing the whole herd to a replicating PRRSv to boost herd immunity. Either modified-live virus (MLV vaccine or live field-virus inoculation (FVI is used. This study consisted of partial budget analyses to compare MLV to FVI as the exposure method of load-close-expose program to control and eliminate PRRSv from infected breeding herds, and secondly to estimate benefit / cost of vaccinating sow herds preventatively. Under the assumptions used in this study, MLV held economic advantage over FVI. However, sensitivity analysis revealed that decreasing margin over variable costs below $ 47.32, or increasing PRRSv-attributed cost above $18.89 or achieving time-to-stability before 25 weeks resulted in advantage of FVI over MLV. Preventive vaccination of sow herds was beneficial when the frequency of PRRSv infection was at least every 1 year and 9 months [corrected]. The economics of preventative vaccination was minimally affected by cost attributed to field-type PRRSv infection on growing pigs or by the breeding herd productivity level. The models developed and described in this paper provide valuable tools to assist veterinarians in their efforts to control PRRSv.

    The calculations which underlie efforts to balance marketing spending on customer acquisition and customer retention are usually based on either single- period customer profitability or forecasts of customer lifetime value (CLTV). This paper argues instead for risk-adjusted CLTV, which is termed the economic value (EV) of a customer, as the means for marketing to assess both customer profitability and shareholder value gains.

  15. Optimization Strategy for Economic Power Dispatch Utilizing Retired EV Batteries as Flexible Loads

    Directory of Open Access Journals (Sweden)

    Shubo Hu

    2018-06-01

    Full Text Available With the increasing penetration of new and renewable energy, incorporating variable adjustable power elements on the demand side is of particular interest. The utilization of batteries as flexible loads is a hot research topic. Lithium-ion batteries are key components in electric vehicles (EVs in terms of capital cost, mass and size. They are retired after around 5 years of service, but still retain up to 80% of their nominal capacity. Disposal of waste batteries will become a significant issue for the automotive industry in the years to come. This work proposes the use of the second life of these batteries as flexible loads to participate in the economic power dispatch. The characteristics of second life batteries (SLBs are varied and diverse, requiring a new optimization strategy for power dispatch at the system level. In this work, SLBs are characterized and their operating curves are obtained analytically for developing an economic power dispatch model involving wind farms and second life batteries. In addition, a dispatch strategy is developed to reduce the dispatch complex brought by the disperse spatial and time distribution of EVs and decrease the system operating cost by introducing incentive and penalty costs in regulating the EV performance. In theory, SLBs are utilized to reduce the peak-valley difference of power loads and to stabilize the power system. Test results based on a ten-unit power system have verified the effectiveness of the proposed dispatch model and the economic benefit of utilizing SLBs as flexible loads in power systems. This work may provide a viable solution to the disposal of waste batteries from EVs and to the stable operation of fluctuating power systems incorporating stochastic renewable energy.

    The International Symposium on Nuclear Fuel Cycle and Reactor Strategies: Adjusting to New Realities was held from 3 to 6 June 1997 in Vienna, Austria. It was organized by the International Atomic Energy Agency (IAEA) in co-operation with the European Commission, the Nuclear Energy Agency of the OECD (OECD/NEA) and the Uranium Institute (UI). More than 300 participants from more than 40 countries and 5 organizations took part. The reason for organizing the symposium was to face the new realities in the nuclear fuel cycle and to come to conclusions on how these new realities should be addressed. In the light of these objectives, international working groups prepared key issue papers on six topics that were selected as the central themes for consideration at the symposium. An International Steering Group composed of the representatives of 12 countries and three international organizations co-ordinated the work of the six working groups. Each of the six working groups wrote a key issue paper. These key issue papers are published as a separate publication. During the symposium, addresses and papers presented by leading experts and policy makers provided additional information in these fields. The key issues were explored further in discussions by the participants and a panel of experts, which helped to highlight the main problems to be addressed in designing the policies for the nuclear fuel cycle in the next 50 years. Special emphasis was placed on the problem of disposition of separated plutonium of civil origin and of plutonium originating from the dismantlement of nuclear weapons.

    Lynch syndrome (LS) is an inherited autosomal dominant disorder characterised by an increased risk of colorectal cancer (CRC) and other cancers, and caused by mutations in the deoxyribonucleic acid (DNA) mismatch repair genes. To evaluate the accuracy and cost-effectiveness of strategies to identify LS in newly diagnosed early-onset CRC patients (aged strategies for individuals in whom LS is identified. Systematic reviews were conducted of the test accuracy of microsatellite instability (MSI) testing or immunohistochemistry (IHC) in individuals with CRC at risk of LS, and of economic evidence relating to diagnostic strategies for LS. Reviews were carried out in April 2012 (test accuracy); and in February 2012, repeated in February 2013 (economic evaluations). Databases searched included MEDLINE (1946 to April week 3, 2012), EMBASE (1980 to week 17, 2012) and Web of Science (inception to 30 April 2012), and risk of bias for test accuracy was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) quality appraisal tool. A de novo economic model of diagnostic strategies for LS was developed. Inconsistencies in study designs precluded pooling of diagnostic test accuracy results from a previous systematic review and nine subsequent primary studies. These were of mixed quality, with significant methodological concerns identified for most. IHC and MSI can both play a part in diagnosing LS but neither is gold standard. No UK studies evaluated the cost-effectiveness of diagnosing and managing LS, although studies from other countries generally found some strategies to be cost-effective compared with no testing. The de novo model demonstrated that all strategies were cost-effective compared with no testing at a threshold of £20,000 per quality-adjusted life-year (QALY), with the most cost-effective strategy utilising MSI and BRAF testing [incremental cost-effectiveness ratio (ICER) = £5491 per QALY]. The maximum health benefit to the

  5. Towards People-Centred Economic Reintegration? An Analysis of the Economic Reintegration Strategy of Demobilised Combatants in Colombia

    Directory of Open Access Journals (Sweden)

    Stefan Thorsell

    2013-04-01

    Full Text Available This paper investigates the suitability of the economic reintegration strategy for former Colombian combatants, taking into account the challenges facing this population. It argues that the international discourse primarily consists of a market-centred versus a people-centred perspective, each with a distinct approach to economic reintegration. The paper finds that in Colombia there was a lack of inclusion of key stakeholders in the initial design of the process. As a result, the economic reintegration strategy ended up merely accommodating certain neoliberal ideals and thereby leaned towards a market-centred approach. Lately, steps have been taken towards an increasingly people-centred approach. This is currently reflected in improved results of the process, which predict a brighter future for economic reintegration of former combatants in Colombia.

    2014-01-01

    Focusing specifically on the experiences of economically disadvantaged preschoolers, the relations between interpersonal violence exposure, behavior problems, and social skills were examined in both the home and school settings. In this racially and ethnically diverse sample of preschoolers from poor, urban households (N = 64; 3-6 years old; 56% female), many children (33%) had been exposed to at least one type of interpersonal violence, and even more (70%) had been exposed to any type of potentially traumatic event (PTE). Although exposure to interpersonal violence was not directly associated with parent- or teacher-reported behavior problems or social skills, a significant interaction effect was observed between exposure to interpersonal violence and teacher-reported internalizing problems in predicting teacher-reported social skills; specifically, for children with the highest levels of internalizing problems, a positive relation between interpersonal violence exposure and social skills was observed. This indirect effect was observed only in the school setting, whereas children in this high-risk sample appeared to demonstrate resilience in the home setting. Given these high rates of exposure, additional, clinically-relevant research is needed to inform interventions for this vulnerable population. PMID:25175528

    2012-12-01

    Strategies for localizing parathyroid pathology preoperatively vary in cost and accuracy. Our purpose was to compute and compare comprehensive costs associated with common localization strategies. A decision-analytic model was developed to evaluate comprehensive, short-term costs of parathyroid localization strategies for patients with primary hyperparathyroidism. Eight strategies were compared. Probabilities of accurate localization were extracted from the literature, and costs associated with each strategy were based on 2011 Medicare reimbursement schedules. Differential cost considerations included outpatient versus inpatient surgeries, operative time, and costs of imaging. Sensitivity analyses were performed to determine effects of variability in key model parameters upon model results. Ultrasound (US) followed by 4D-CT was the least expensive strategy ($5,901), followed by US alone ($6,028), and 4D-CT alone ($6,110). Strategies including sestamibi (SM) were more expensive, with associated expenditures of up to $6,329 for contemporaneous US and SM. Four-gland, bilateral neck exploration (BNE) was the most expensive strategy ($6,824). Differences in cost were dependent upon differences in the sensitivity of each strategy for detecting single-gland disease, which determined the proportion of patients able to undergo outpatient minimally invasive parathyroidectomy. In sensitivity analysis, US alone was preferred over US followed by 4D-CT only when both the sensitivity of US alone for detecting an adenoma was ≥ 94 %, and the sensitivity of 4D-CT following negative US was ≤ 39 %. 4D-CT alone was the least costly strategy when US sensitivity was ≤ 31 %. Among commonly used strategies for preoperative localization of parathyroid pathology, US followed by selective 4D-CT is the least expensive.

    Criqui, Patrick; Mima, Silvana; Peytral, Pierre-Olivier; Simon, Jean-Christophe

    2012-01-01

    In an article published in these pages in 2011 (no. 373), Patrick Criqui presented a series of scenarios on possible energy and climate trends, taking note of the agreement on climate change signed in late 2009 at the Copenhagen Conference. He pointed out that a paradigm shift was on the cards, which would mean less use of the top-down approach - with national objectives set as a function of international objectives formulated at major conferences - and greater implementation of a bottom-up logic based on national policies put in place in the energy field and as part of the battle against global warming. On the basis of this latter logic, the authors were able to elaborate scenarios at a world level. A few days before the publication of that article, the Fukushima accident occurred in japan, lending fresh impetus to the energy debate in most of the countries using nuclear power. Does that event, combined with the persistence of the debt crisis, the increased extraction of unconventional hydrocarbons (shale oil and gas ) and the fact that international negotiations on climate change (Durban) have merely marked time, modify the projected scenarios -and, if so, to what extent ? Patrick Criqui, Silvana Mima, Pierre-Olivier Peytral and jean-Christophe Simon consider this question in detail here. They begin by examining the impact of these recent events and developments on the current energy and climate situation. Then, after reminding us of the four world energy scenarios (to a time-horizon of 2030-2050) that were developed in 2009 (together with two 'discontinuity scenarios'), they propose an updating that takes account of the perceived consequences of the change of context, stressing two crucial scenarios in particular: the probable (leading to warming in the order of 4 deg. C) and the desirable (limiting warming to 2 deg. C). Lastly, they propose various levers aimed at 'making the desirable trajectory possible' (technological agreements, economic instruments

    The analysis of technical and parametric constraints on the adjustment range of highpower CCP and recommended technological solutions in the technical literature for their elimination. Established that in the conditions of toughening the requirements for economy, reliability and maneuverability on the part of the system operator with the participation of CCP in control the frequency and power in the power system, existing methods do not ensure the fulfillment of these requirements. The current situation in the energy sector — the lack of highly manoeuvrable power equipment leads to the need participate in control of power consumption diagrams for all types of power plants, including CCP, although initially they were intended primarily for basic loads. Large-scale research conducted at the department of Automated control systems of technological processes, showed the possibility of a significant expansion of the adjustment range of CCP when it operating in the condensing mode and in the heating mode. The report presents the main results of these research for example the CCP-450 and CCP-450T. Various technological solutions are considered: when CCP in the condensation mode — the use of bypass steam distribution schemes, the transfer of a part of the steam turbine into a low-steam mode; when CCP operation in the heating mode — bypass steam distribution and the transfer CCP to gas turbine unit — power heating plants mode with the transfer the steam turbine to the motor mode. Data on the evaluation of the technical and economic feasibility of the proposed innovative technological solutions are presented in comparison with the methods used to solve this problem, which are used in practice, such as passing through the failures of the electric load graphs by transferring the CCP to the mode of operation with incomplete equipment. When comparing, both the economics, and the maneuverability and reliability of the equipment are considered.

    Flouri, Eirini; Midouhas, Emily; Ruddy, Alexandra

    2016-01-01

    We examined the effects of single-parent family status and high parental socio-economic status (SES) on the trajectories of children's emotional/behavioural adjustment in early-to-middle childhood (ages 3-7 years). We also assessed whether these family characteristics interact with the equivalent neighbourhood characteristics of shares of single-parent families and high-SES adults in predicting these trajectories. Using data on 9850 children in England participating in the Millennium Cohort Study, we found that family status and parental SES predicted children's trajectories of adjustment. Even after controlling for these family factors and key child and parent characteristics, the neighbourhood shares of high-SES adults and single-parent families were related (negatively and positively, respectively) to child problem behaviour. Importantly, children of low-SES parents in neighbourhoods with a high concentration of high-SES adults had fewer emotional symptoms than their counterparts in areas with fewer high-SES adults. Surprisingly, the adverse effect of single-parent family status on child hyperactivity was attenuated in areas with a higher share of single-parent families. Copyright © 2015 The Authors.

    2014-01-01

    Full Text Available Sustainable economic development has become an important area of concern due to climatic change with its long term effects. Climatic change has posed several challenges for economic sustainability of economies. Now major development projects have to comply with international environmental norms. Failure to do so may result in the delay of a project, fines including penalties for environmental damage or charges for remedial action, that affect the viability of a project or the value of any security taken. This paper investigates with help of secondary date using descriptive statistical technique opportunities and challenges of green investment. Here it is developed into suitable model for developing economies for successfully adopting green investment without much cost to their economies. The paper concludes that green investment involving direct investment and portfolio investment in firms adopting and following environmental protection norms will lead to sustainable growth and investment for economy.

    2011-06-01

    To appraise economic evaluations of health technologies that included quality-adjusted life-years (QALYs) as an outcome measure conducted over the past 20 years in Spain. A systematic review of the literature was conducted. Economic evaluations that included QALYs as an outcome measure, conducted in Spain and published between January 1990 and December 2009 were identified. Primary and gray literature sources were reviewed. A total of 60 articles and 4 health technology assessment reports were included. Key findings were 1) the vast majority of articles (77.1%) referred to therapeutic interventions; 2) 63.2% dealt with pharmaceutical products and much fewer with preventive strategies, medical devices, or diagnostic interventions; 3) most evaluations referred to cardiovascular- (19.8%), respiratory- (16.3%), and cancer- (13.0%) related processes; 4) 80.3% were based on a theoretical model, most commonly Markov models (71.4%); 5) 67.3% adopted the National Health System perspective; 6) information on the methods used to describe the health states was given in 45.1% of studies; 7) 40.3% used the EuroQoL-5D to elicit preferences, whereas 66.1% gave no details on the methods applied to determine patients' choices; 8) it was possible to state who completed the questionnaires in only 17.7% of studies; 9) 77.1% of the interventions assessed were below the €30,000/QALY suggested affordable threshold in Spain. An increasing number of economic evaluations using QALYs had been conducted. Most of them relied on theoretical models. Several methodological issues remain unsolved. Great disparity exists regarding the reporting of the methods used to determine health states and utility values. Copyright © 2011. Published by Elsevier Inc.

    Highlights: • The optimal adjustment method for SSPS when it travels on orbit is determined. • Two solutions for the arrangement of transverse truss are proposed. • The effect and regulating method for the tracking error are investigated. • The mathematical partition model of a flat hexagon module concept is built. • The flux distributions on solar panel based on different number of modules are simulated. - Abstract: Space Solar Power Station (SSPS) is a very potential candidate for supplying abundant electrical energy. Symmetrical two-stage flat reflected concentrator (STFC) has many advantages when used in SSPS. However the steady performance and control method on orbit has become a big problem which will be discussed in this paper. The actual posture of entire station is analyzed in detail due to the requirements of good flux uniformity, circular concentrated spot and controlled concentration ratio. Here two regulating directions are studied. And the most optimal method in multidimensional space of adjusting parameters is developed. In order to verify the correctness and reliability, the concentrating characteristics in different cases are simulated by Monte-Carlo ray tracing method (MCRTM). Based on the optimal adjusting parameters, solutions for the arrangement of transverse truss are proposed. After that the effect and regulating method for tracking error is investigated to improve the tolerance performance as highly as possible. Finally the construction of concentrators is much important to the realizability, cost and working performance. A flat hexagon module concept and the regular pattern are investigated to build the optical model. The flux distribution on solar panel based on different big number of modules is simulated, which provides certain reference for the build of SSPS

Also, having Egalitarian Gender Role Attitude effects the psychological symptoms in relation with the marital relationship, but it is seen that this effect is not higher enough to play a mediator role (Sobel z =-1.21, p>.05). Regression analysis showed that there is a statistically significant correlation between women's marital adjustment and their psychological symptoms, indicating that the marital adjustment decreases as the psychological symptoms increases. It is also found out that submissive and helpless coping approach have mediator roles in this relationship. Also, contrary to expectations, having egalitarian gender role attitude effects the psychological symptoms in relation with the marital relationship, but this effect does not seem to play a mediator role. It is thought that the effects of marriage and couple therapy approaches considering couples’s problem solving and coping styles should be examined in further studies.

    The experiments were so designed and carried out that it was even possible for extremely overexposed or underexposed displays to be ascertained within the framework of this study. They were based on observations in phantoms suitable to simulate situations encountered in actual practice. These permitted variations in patient volume (using different water volumes) just as well as the creation of any desired organ constellation (by insertion of bone material, etc.). It is one requirement of this experimental procedure that the X-ray unit used can be operated without automatic dose rate adjustment. A computer equipped with Frame-Grabber card may serve as an image memory. (orig.) [de

  1. Shifts in growth strategies reflect tradeoffs in cellular economics

    2009-01-01

    The growth rate-dependent regulation of cell size, ribosomal content, and metabolic efficiency follows a common pattern in unicellular organisms: with increasing growth rates, cell size and ribosomal content increase and a shift to energetically inefficient metabolism takes place. The latter two phenomena are also observed in fast growing tumour cells and cell lines. These patterns suggest a fundamental principle of design. In biology such designs can often be understood as the result of the optimization of fitness. Here we show that in basic models of self-replicating systems these patterns are the consequence of maximizing the growth rate. Whereas most models of cellular growth consider a part of physiology, for instance only metabolism, the approach presented here integrates several subsystems to a complete self-replicating system. Such models can yield fundamentally different optimal strategies. In particular, it is shown how the shift in metabolic efficiency originates from a tradeoff between investments in enzyme synthesis and metabolic yields for alternative catabolic pathways. The models elucidate how the optimization of growth by natural selection shapes growth strategies. PMID:19888218

    Full Text Available The Great Recession, which began in late 2007, is manifested primarily as employment crisis and mainly affects the immigrant population. Most immigrants have decided to remain in Spain, and to mitigate the effects of the crisis, several strategies have been deployed in the productive and reproductive spheres. One response to the progressive degradation of the labor market has been the internal and transnational geographical mobility, which takes various strategies: return to the country of origin, migration to a third country, and circular migration. The information used in this article comes from in-depth interviews to 64 citizens of Romania and Bulgaria residing in Spain, as well as from and 32 other interviews to family members and returnees, which took place in their countries. To the information coming from the emigrants we add socioeconomic data provided by the National Institute of Statistics and the Ministry of Employment.

    Policy decision-making in cardiovascular disease is increasingly informed by the results generated from decision-analytic models (DAMs). The methodological approaches and assumptions used in these DAMs impact on the results generated and can influence a policy decision based on a cost per quality-adjusted life year (QALY) threshold. Decision makers need to be provided with a clear understanding of the key sources of evidence and how they are used in the DAM to make an informed judgement on the quality and appropriateness of the results generated. Our review identified 12 studies exploring the cost-effectiveness of pharmaceutical lipid-lowering interventions published since January 2010. All studies used Markov models with annual cycles to represent the long-term clinical pathway. Important differences in the model structures and evidence base used within the DAMs were identified. Whereas the reporting standards were reasonably good, there were many instances when reporting of methods could be improved, particularly relating to baseline risk levels, long-term benefit of treatment and health state utility values. There is a scope for improvement in the reporting of evidence and modelling approaches used within DAMs to provide decision makers with a clearer understanding of the quality and validity of the results generated. This would be assisted by fuller publication of models, perhaps through detailed web appendices.

  4. Do characteristics of a stationary obstacle lead to adjustments in obstacle stepping strategies?

    Navigating cluttered and complex environments increases the risk of falling. To decrease this risk, it is important to understand the influence of obstacle visual cues on stepping parameters, however the specific obstacle characteristics that have the greatest influence on avoidance strategies is still under debate. The purpose of the current work is to provide further insight on the relationship between obstacle appearance in the environment and modulation of stepping parameters. Healthy young adults (N=8) first stepped over an obstacle with one visible top edge ("floating"; 8 trials) followed by trials where experimenters randomly altered the location of a ground reference object to one of 7 different positions (8 trials per location), which ranged from 6cm in front of, directly under, or up to 6cm behind the floating obstacle (at 2cm intervals). Mean take-off and landing distance as well as minimum foot clearance values were unchanged across different positions of the ground reference object; a consistent stepping trajectory was observed for all experimental conditions. Contrary to our hypotheses, results of this study indicate that ground based visual cues are not essential for the planning of stepping and clearance strategies. The simultaneous presentation of both floating and ground based objects may have provided critical information that lead to the adoption of a consistent strategy for clearing the top edge of the obstacle. The invariant foot placement observed here may be an appropriate stepping strategy for young adults, however this may not be the case across the lifespan or in special populations.

    The International Symposium on Nuclear Fuel Cycle and Reactor Strategy: Adjusting to New Realities was held from 3 to 6 June 1997 in Vienna, Austria. The objective of the Symposium was to prepare for decision makers and the public, a scientific assessment of the different fuel cycle and reactor strategies with particular reference to the production, use and disposition of plutonium. Six key issue papers were prepared by six groups of international experts which summarized the international common understanding of the various fuel cycle issues including those related to technology, safety, safeguards, environmental and institutional developments. This paper summarizes the major finding of the Working Groups except for Working Group 3 which will be presented in depth in a separate paper in this Technical Committee Meeting. (author)

  7. The Influence of Community Management Agreements on Household Economic Strategies : Cattle Grazing and Fishing Agreements on the Lower Amazon Floodplain

    Directory of Open Access Journals (Sweden)

    David G. McGrath

    2007-10-01

    Full Text Available While the organizational dynamics of collective management systems have received much attention, relatively little work has focused on how households adapt their economic strategies in response to collective management regulations that impose constraints on the range of options available to households. In this paper we investigate the evolving interaction between household management strategies and collective management regulations for one or both of two ecologically interdependent floodplain resources, lake fisheries and seasonally inundated grasslands. Smallholder management strategies involve varying combinations of three main activities each associated with one of three main floodplain habitats: annual cropping on river levees, cattle ranching on natural grasslands and fishing in lakes. These three activities play complementary roles in the household economy. Annual cropping is both subsistence and market oriented, with cash from crop sales often invested in purchase of cattle. Fishing, in addition to providing animal protein, generates income for household purchases while crops are growing. Cattle ranching is the main savings strategy for smalholders, providing funds for family emergencies and capital investments. Despite the fertility of soils and the higher productivity per hectare of fishing, cattle ranching has expanded steadily on the floodplain at the expense of farming and fishing. Over the last two decades, communities throughout the Amazon floodplain have developed and implemented collective agreements to regulate access to and use of local lake fisheries. Depending on the measures included, the impact of these agreements on household management strategies can range from negligible to highly significant, requiring major adjustments to compensate for reduced fishing income. Expansion of smallholder cattle ranching has taken advantage of unregulated access to community grasslands. Unregulated access to community grasslands has been a

    Volatile fatty acid (VFA) production from three types of high-strength organic wastewater (cassava thin stillage, starch wastewater and yellow-wine processing wastewater) were compared. The results showed that cassava thin stillage was the most suitable substrate, based on its high specific VFA production (0.68 g chemical oxygen demand (COD)/g initial soluble chemical oxygen demand (SCOD)) and yield (0.72 g COD/g SCOD) as well as low nutrient content in the substrate and fermented liquid. The acid fermented cassava thin stillage was evaluated and compared with sodium acetate in a sequencing batch reactor system. Total nitrogen removal efficiency was higher with fermented cassava thin stillage than with the sodium acetate. The effects of pH and a pH-adjustment strategy on VFA production and composition were determined using cassava thin stillage. At an initial pH range of 7-11, a relatively high VFA concentration of about 9 g COD/L was obtained. The specific VFA production (g COD/g initial SCOD) increased from 0.27 to 0.47 to 0.67 at pH 8 and from 0.26 to 0.68 to 0.81 at pH 9 (initial pH, interval pH, and constant pH adjustment, respectively). The dominant VFA species changed significantly with the increasing frequency of the pH adjustment. Further studies will examine the metabolic pathways responsible for VFA composition.

    Full Text Available Objective. Activity patterns are the product of pain and of the self-regulation of current goals in the context of pain. The aim of this study was to investigate the association between goal management strategies and activity patterns while taking into account the role of optimism/pessimism and positive/negative affect. Methods. Two hundred and thirty-seven patients with chronic musculoskeletal pain filled out questionnaires on optimism, positive and negative affect, pain intensity, and the activity patterns they employed in dealing with their pain. Questionnaires were also administered to assess their general goal management strategies: goal persistence, flexible goal adjustment, and disengagement and reengagement with goals. Results. Structural equation modelling showed that higher levels of optimism were related to persistence, flexible goal management, and commitment to new goals. These strategies were associated with higher positive affect, persistence in finishing tasks despite pain, and infrequent avoidance behaviour in the presence or anticipation of pain. Conclusions. The strategies used by the patients with chronic musculoskeletal pain to manage their life goals are related to their activity patterns.

    To evaluate and adjust systematic implementation of guided family-centred care in a neonatal intensive care unit. Family-centred care is valued in neonatal intensive care units internationally, but innovative strategies are needed to realise the principles. Guided family-centred care was developed to facilitate person-centred communication by bridging the gap between theory and practice in family-centred care. Main mechanisms of guided family-centred care are structured dialogue, reflection and person-centred communication. Qualitative and quantitative data were used to monitor participatory implementation of a systematic approach to training and certification of nurses delivering guided family-centred care. Systematic implementation of guided family-centred care included workshops, supervised delivery and certification. Evaluation and adjustment of nurse adherence to guided family-centred care was conducted by monitoring (1) knowledge, (2) delivery, (3) practice uptake and (4) certification. Implementation was improved by the development of a strategic framework and by adjusting the framework according to the real-life context of a busy neonatal care unit. Promoting practice uptake was initially underestimated, but nurse guided family-centred care training was improved by increasing the visibility of the study in the unit, demonstrating intervention progress to the nurses and assuring a sense of ownership among nurse leaders and nonguided-family-centred-care-trained nurses. An adjusted framework for guided family-centred care implementation was successful in overcoming barriers and promoting facilitators. Insights gained from our pioneering work might help nurses in a similar context to reach their goals of improving family-centred care. © 2014 John Wiley & Sons Ltd.

    To provide information from a review of literature about economic evaluations of preventive strategies for pressure injuries (PIs). This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to:1. Identify the purpose and methods used for this study.2. Compare costs and effectiveness related to preventative strategies for PIs. BACKGROUND: Pressure injuries (PIs) are a common and resource-intensive challenge for acute care hospitals worldwide. While a number of preventive strategies have the potential to reduce the cost of hospital-acquired PIs, it is unclear what approach is the most effective. The authors performed a narrative review of the literature on economic evaluations of preventive strategies to survey current findings and identify important factors in economic assessments. Ovid, MEDLINE, NHS Economic Evaluation Databases, and the Cochrane Database of Systematic ReviewsSELECTION CRITERIA: Potentially relevant original research articles and systematic reviews were considered. Selection criteria included articles that were written in English, provided data on cost or economic evaluations of preventive strategies of PIs in acute care, and published between January 2004 and September 2015. Data were abstracted from the articles using a standardized approach to evaluate how the items on the Consolidated Health Economic Evaluation Reporting Standards checklist were addressed. The searches identified 192 references. Thirty-three original articles were chosen for full-text reviews. Nineteen of these articles provided clear descriptions of interventions, study methods, and outcomes considered. Limitations in the available literature prevent firm conclusions from being reached about the relative economic merits of the various approaches to the prevention of PIs. The authors' review

    Full Text Available The analysis of the evolutionary stages of the scientific and methodological support of the branding of cities is presented and the components of the city brand related to the basic indicators of its social and economic development are proposed. It is proved that under the current conditions of economic globalization and regional integration, the competition between territories is intensifying, which requires local authorities to develop new approaches to the branding of cities. The aim of the article is to substantiate the components of the city branding in the development of the strategy of social and economic development of the city. Analysis of the stages of evolution of scientific and methodological support for the branding of cities demonstrates the expansion of its tools and its inclusion in the strategies of social and economic development of cities. It is determined that the main constituents of the city brand are: importance of the city in the country and the region; human capital; economy, industry, innovations; ease of doing business; health protection; education, culture, sport, urban infrastructure. Methodical approach to the implementation of the city branding within the framework of its socio-economic development strategy involves the implementation of interrelated stages: SWOT analysis of the social and economic system of the city; formation of the list of competitive advantages of the city; determination of priority directions for the development of the city, etc.

    Full Text Available Economic diplomacy is known as a symbol of the European Union and represents its primary function. With the development of science and new ways of communication, the European Union can organize a new approach for its economic diplomacy. The main advantage of the European Union as a soft power is that its economic and diplomatic interests are represented in a manner that is based not on confrontation but economic collaboration with other states. The disadvantage is that this domain is presently not used enough to represent EU interests. This paper describes economic diplomacy in general and the economic diplomacy of the EU in particular. Divided into three parts, the goal of this study is to outline the importance of economic diplomacy, its evolution, the influence of this domain on the creation of previous economic treaties, and its possible future impact on the development of new agreements between the European Union and its neighbor countries.The main methodology used is descriptive, presenting the evolution of this field and the new business strategies that can be used to improve cooperation at the eastern border of the European Union. Therefore here are presented the historical background of EU Economic diplomacy, its present issues, and future challenges. The quantitative data used in this research paper are based on information from the EU website and on the actual events concerning debates about economic diplomacy and its future. The research questions presented herein follow the general evolution of this domain and its mutual influence with EU’s businesses strategies.

The survey-correlational method was used with teaching performance as dependent variables, experienced economic difficulties as the independent variable, and coping strategy as moderator variable. The participants in the study were the 52 faculty who were selected through purposive sampling. Data were gathered through a researcher-made questionnaire-checklist and Faculty Performance Evaluation System. The statistical tools used were frequency count, rank, mean, standard deviation, and Pearson's Product-Moment Coefficient of Correlation. All statistical computations were availed of through the Statistical Package for the Social Sciences (SPSS software. Results revealed that the top economic difficulty experienced by faculty was limited cash. The topmost coping strategy employed by faculty was buying only basic foods or things for household. The faculty also experienced economic difficulty to a “moderate extent.” Nevertheless, the performance of the faculty was found to be “outstanding.” Teachers were affected by such financial crisis. However, despite their experienced economic difficulties, as major agents for change, they performed their best for the improvement of quality education. No significant relationships existed between coping strategies and teaching performance of faculty.

    Technical constraints can leave a considerable freedom in the design of a technology, production or service strategy. Choosing between economical or ecological decision criteria then characteristically leads to controversial solutions of ideal systems. For the adaptation of granular-activated carbon (GAC) fixed beds, various technical factors determine the adsorber volume required to achieve a desired service life. In considering carbon replacement and recycling, a variety of refill strategies are available that differ in terms of refill interval, respective adsorber volume, and time-dependent use of virgin, as well as recycled GAC. Focusing on the treatment of contaminant groundwater, we compare cost-optimal reactor configurations and refill strategies to the ecologically best alternatives. Costs and consumption of GAC are quantified within a technical-economical framework. The emissions from GAC production out of hard coal, transport and recycling are equally derived through a life cycle impact assessment. It is shown how high discount rates lead to a preference of small fixed-bed volumes, and accordingly, a high number of refills. For fixed discount rates, the investigation reveals that both the economical as well as ecological assessment of refill strategies are especially sensitive to the relative valuation of virgin and recycled GAC. Since recycling results in economic and ecological benefits, optimized systems thus may differ only slightly.

    Full Text Available In the fields of production, manufacturing and supply chain management, Radio Frequency Identification (RFID is regarded as one of the most important technologies. Nowadays, Mobile RFID, which is often installed in carts or forklift trucks, is increasingly being applied to the search for and checkout of items in warehouses, supermarkets, libraries and other industrial fields. In using Mobile RFID, since the readers are continuously moving, they can interfere with each other when they attempt to read the tags. In this study, we suggest a Time Division Multiple Access (TDMA based anti-collision algorithm for Mobile RFID readers. Our algorithm automatically adjusts the frame size of each reader without using manual parameters by adopting the dynamic frame size adjustment strategy when collisions occur at a reader. Through experiments on a simulated environment for Mobile RFID readers, we show that the proposed method improves the number of successful transmissions by about 228% on average, compared with Colorwave, a representative TDMA based anti-collision algorithm.

Our algorithm automatically adjusts the frame size of each reader without using manual parameters by adopting the dynamic frame size adjustment strategy when collisions occur at a reader. Through experiments on a simulated environment for Mobile RFID readers, we show that the proposed method improves the number of successful transmissions by about 228% on average, compared with Colorwave, a representative TDMA based anti-collision algorithm.

    Full Text Available Purpose of the article: The article analyzes the current state of information technology in terms of their use in a strategy creation of a company in relation to monitoring the economic results of a company. It investigates, identifies and evaluates the overall situation of the concept and principles of these tools, their effectiveness in drawing up the strategy and strategic company goals, the ability to perform a variety of economic analysis without the need of a complex operation and understanding, but also for an effective evaluation of data for a planning support, management and deciding of management components, leading to the overall success of a company. The reason for this monitoring is a considerable difference between strategic company planning and its real results. Methodology/methods: In terms of methodology, the literature review of the current state of the issue has been used. – Primary: interviews, observations, expert estimation. – Secondary: evaluation of the data from the database of IS, documentation of seminars. – Quantitative Research: mapping the orientation of the issue, the confrontation with the theory. – Qualitative research: projective, structured interview (by users and suppliers. Scientific aim: The main aim of the work is to solve the problems of management and evaluation of the economic process in respect of information technology tools in connection with the formation of corporate strategy and monitoring of financial results of the company. The reason for selecting of the above-mentioned issue is the fact that information technology resources are currently not used in the creation of corporate strategy, specifically in the area of economic goals. Findings: To describe the situation in the region and to clearly define the basic problems used as a basis for the use of IT support tools in creation of corporate strategy, namely economic goals and the use of feedback of information support tools for assessing

    Treatment switching commonly occurs in clinical trials of novel interventions in the advanced or metastatic cancer setting. However, methods to adjust for switching have been used inconsistently and potentially inappropriately in health technology assessments (HTAs). We present recommendations on the use of methods to adjust survival estimates in the presence of treatment switching in the context of economic evaluations. We provide background on the treatment switching issue and summarize methods used to adjust for it in HTAs. We discuss the assumptions and limitations associated with adjustment methods and draw on results of a simulation study to make recommendations on their use. We demonstrate that methods used to adjust for treatment switching have important limitations and often produce bias in realistic scenarios. We present an analysis framework that aims to increase the probability that suitable adjustment methods can be identified on a case-by-case basis. We recommend that the characteristics of clinical trials, and the treatment switching mechanism observed within them, should be considered alongside the key assumptions of the adjustment methods. Key assumptions include the "no unmeasured confounders" assumption associated with the inverse probability of censoring weights (IPCW) method and the "common treatment effect" assumption associated with the rank preserving structural failure time model (RPSFTM). The limitations associated with switching adjustment methods such as the RPSFTM and IPCW mean that they are appropriate in different scenarios. In some scenarios, both methods may be prone to bias; "2-stage" methods should be considered, and intention-to-treat analyses may sometimes produce the least bias. The data requirements of adjustment methods also have important implications for clinical trialists.

    2004-08-01

    We are extending the existing features of Aspen, a powerful economic modeling tool, and introducing new features to simulate the role of confidence in economic activity. The new model is built from a collection of autonomous agents that represent households, firms, and other relevant entities like financial exchanges and governmental authorities. We simultaneously model several interrelated markets, including those for labor, products, stocks, and bonds. We also model economic tradeoffs, such as decisions of households and firms regarding spending, savings, and investment. In this paper, we review some of the basic principles and model components and describe our approach and development strategy for emulating consumer, investor, and business confidence. The model of confidence is explored within the context of economic disruptions, such as those resulting from disasters or terrorist events.

  14. One idea of portfolio risk control for absolute return strategy risk adjustments by signals from correlation behavior

    Absolute return strategy provided from fund of funds (FOFs) investment schemes is the focus in Japanese Financial Community. FOFs investment mainly consists of hedge fund investment and it has two major characteristics which are low correlation against benchmark index and little impact from various external changes in the environment given maximizing return. According to the historical track record of survival hedge funds in this business world, they maintain a stable high return and low risk. However, one must keep in mind that low risk would not be equal to risk free. The failure of Long-term capital management (LTCM) that took place in the summer of 1998 was a symbolized phenomenon. The summer of 1998 exhibited a certain limitation of traditional value at risk (VaR) and some possibility that traditional VaR could be ineffectual to the nonlinear type of fluctuation in the market. In this paper, I try to bring self-organized criticality (SOC) into portfolio risk control. SOC would be well known as a model of decay in the natural world. I analyzed nonlinear type of fluctuation in the market as SOC and applied SOC to capture complicated market movement using threshold point of SOC and risk adjustments by scenario correlation as implicit signals. Threshold becomes the control parameter of risk exposure to set downside floor and forecast extreme nonlinear type of fluctuation under a certain probability. Simulation results would show synergy effect of portfolio risk control between SOC and absolute return strategy.

    Full Text Available The article explores dairy and cheese production at family farms in Bohinj, their economical and organisational strategies (variations between family and cooperative organisation of farming and the connection of cheese production with different modes of spatial movement. In the past decade, several family farms have started producing cheese and milk products, which is an economic activity closely linked to traditional forms of cooperatives, and pasture rights of agricultural societies. These farms have revitalised traditional forms of cheese production and established new economic strategies, especially through the plurality of their activities – work outside of the farm, tourism, marketing of their products, etc. The article first presents a development of cheese production in Bohinj, changes in family and cooperative farming and explores movement and the meshwork of paths, tracks, roads and places that are fundamental to cheese economy. Further, the article connects different movements, e.g. daily pastures close to the villages, transhumance in mountain pasturelands, selling products in markets, etc. Modes of movement (walk, cattle herding, driving to markets are basic practices behind economic strategies of dairy and cheese farms, as well as organisations and use of space, in particular mountain paths and pasturelands.

    Four semen traits: volume (VOL), concentration (CON), progressive motility of spermatozoa (MOT), and abnormal spermatozoa (ABN) provide complementary information on boar fertility. Assessment of the impact of selection for semen traits is hindered by limited information on economic parameters. Objectives of this study were to estimate economic values for semen traits and to evaluate the genetic gain when these traits are incorporated into traditional selection strategies in a 3-tier system of swine production. Three-way (maternal nucleus lines A and B and paternal nucleus line C) and 4-way (additional paternal nucleus line D) crossbreeding schemes were compared. A novel population structure that accommodated selection for semen traits was developed. Three selection strategies were simulated. Selection Strategy I (baseline) encompassed selection for maternal traits: number of pigs born alive (NBA), litter birth weight (LBW), adjusted 21-d litter weight (A21), and number of pigs at 21 d (N21); and paternal traits: number of days to 113.5 kg (D113), backfat (BF), ADG, feed efficiency (FE), and carcass lean % (LEAN). Selection Strategy II included Strategy I and the number of usable semen doses per collection (DOSES), a function of the 4 semen traits. Selection Strategy III included Strategy I and the 4 semen traits individually. The estimated economic values of VOL, CON, MOT, ABN, and DOSES for 7 to 1 collections/wk ranged from $0.21 to $1.44/mL, $0.12 to $0.83/10 spermatozoa/mm, $0.61 to $12.66/%, -$0.53 to -$10.88/%, and $2.01 to $41.43/%, respectively. The decrease in the relative economic values of semen traits and DOSES with higher number of collections per wk was sharper between 1 and 2.33 collections/wk than between 2.33 and 7 collections/wk. The higher economic value of MOT and ABN relative to VOL and CON could be linked to the genetic variances and covariances of these traits. Average genetic gains for the maternal traits were comparable across strategies

    The Response Adjusted for Days of Antibiotic Risk (RADAR) statistic was proposed to improve the efficiency of trials comparing antibiotic stewardship strategies to optimize antibiotic use. We studied the behaviour of RADAR in a non-inferiority trial in which a β-lactam monotherapy strategy (n = 656) was non-inferior to fluoroquinolone monotherapy (n = 888) for patients with moderately severe community-acquired pneumonia. Patients were ranked according to clinical outcome, using five or eight categories, and antibiotic use. RADAR was calculated as the probability that the β-lactam group had a more favourable ranking than the fluoroquinolone group. To investigate the sensitivity of RADAR to detrimental clinical outcome we simulated increasing rates of 90-day mortality in the β-lactam group and performed the RADAR and non-inferiority analysis. The RADAR of the β-lactam group compared with the fluoroquinolone group was 60.3% (95% CI 57.9%-62.7%) using five and 58.4% (95% CI 56.0%-60.9%) using eight clinical outcome categories, all in favour of β-lactam. Sample sizes for RADAR were 38% (250/653) and 89% (580/653) of the non-inferiority sample size calculation, using five or eight clinical outcome categories, respectively. With simulated mortality rates, loss of non-inferiority of the β-lactam group occurred at a relative risk of 1.125 in the conventional analysis, whereas using RADAR the β-lactam group lost superiority at a relative risk of mortality of 1.25 and 1.5, with eight and five clinical outcome categories, respectively. RADAR favoured β-lactam over fluoroquinolone therapy for community-acquired pneumonia. Although RADAR required fewer patients than conventional non-inferiority analysis, the statistic was less sensitive to detrimental outcomes.

    Full Text Available Abstract Background Economic evaluations in the medical literature compare competing diagnosis or treatment methods for their use of resources and their expected outcomes. The best evidence currently available from research regarding both cost and economic comparisons will continue to expand as this type of information becomes more important in today's clinical practice. Researchers and clinicians need quick, reliable ways to access this information. A key source of this type of information is large bibliographic databases such as EMBASE. The objective of this study was to develop search strategies that optimize the retrieval of health costs and economics studies from EMBASE. Methods We conducted an analytic survey, comparing hand searches of journals with retrievals from EMBASE for candidate search terms and combinations. 6 research assistants read all issues of 55 journals indexed by EMBASE for the publishing year 2000. We rated all articles using purpose and quality indicators and categorized them into clinically relevant original studies, review articles, general papers, or case reports. The original and review articles were then categorized for purpose (i.e., cost and economics and other clinical topics and depending on the purpose as 'pass' or 'fail' for methodologic rigor. Candidate search strategies were developed for economic and cost studies, then run in the 55 EMBASE journals, the retrievals being compared with the hand search data. The sensitivity, specificity, precision, and accuracy of the search strategies were calculated. Results Combinations of search terms for detecting both cost and economic studies attained levels of 100% sensitivity with specificity levels of 92.9% and 92.3% respectively. When maximizing for both sensitivity and specificity, the combination of terms for detecting cost studies (sensitivity increased 2.2% over the single term but at a slight decrease in specificity of 0.9%.

    Full Text Available Depressed state of Russian economy in recent years, the unstable functioning of most regional social and economic systems in the conditions of increased uncertainty of the global economy makes strategizing of the development based on a new model of economic growth a highly important issue. It assumes the tasks of modernization and restructuring of the economy, as well as improving the quality of management. It is known that the solution of these conceptual target problems was suggested by the concept 2020, but the global crisis of 2007-2009 and other geopolitical factors in the post-crisis period pushed their implementation back. The results of 2016 show an adaptation of Russian economy to the difficult internal and external challenges. In this article, the authors analyze the strategizing process by the example of the “Strategy of social and economic development of the Kemerovo Region up to 2025”, as well as analysis comparatively the strategies for the development of the national economy, the Siberian Federal District and the region. Based on the study results the authors formulated and substantiated conclusions and recommendations to improve strategizing process and the effectiveness of strategic management of the development of social and economic systems.

    The universalization of basic care and commitment budget of the Ministry of Health with the Family Health Strategy (ESF) through new systematic financing incentives have been highlighted in the Brazilian health policy scenario. One of the great problems observed is the expansion of the strategy for large urban centres. This paper studies the economic-financial sustainability of ESF in Brazilian municipalities of more than 100 thousand inhabitants according to some selected indicators, considering the geographical region to which they belong, their population size and participation in Project for the Expansion and Consolidation Family Health (Proesf). Municipalities belonging to the Southeast region, more developed of the country, have on average better economic-financial performance, but lower average values of coverage of ESF. Municipalities from the North and Northeast, with the lowest average for economic-financial sustainability indicators, were the ones that made more effort to developments in the period. Thus, we observed the dynamics between bigger fiscal capacity and budgetary commitment with the Health Sector for biggest municipalities and in more economically developed regions, and greater vulnerability and dependence of federative transferences for municipalities with less people, in less developed areas.

    Full Text Available School closures as a means of containing the spread of disease have received considerable attention from the public health community. Although they have been implemented during previous pandemics, the epidemiological and economic effects of the closure of individual schools remain unclear.This study used data from the 2009 H1N1 pandemic in Hong Kong to develop a simulation model of an influenza pandemic with a localised population structure to provide scientific justifications for and economic evaluations of individual-level school closure strategies.The estimated cost of the study's baseline scenario was USD330 million. We found that the individual school closure strategies that involved all types of schools and those that used a lower threshold to trigger school closures had the best performance. The best scenario resulted in an 80% decrease in the number of cases (i.e., prevention of about 830,000 cases, and the cost per case prevented by this intervention was USD1,145; thus, the total cost was USD1.28 billion.This study predicts the effects of individual school closure strategies on the 2009 H1N1 pandemic in Hong Kong. Further research could determine optimal strategies that combine various system-wide and district-wide school closures with individual school triggers across types of schools. The effects of different closure triggers at different phases of a pandemic should also be examined.

    Although public health guidelines have implications for resource allocation, these issues were not explicitly considered in previous WHO pandemic preparedness and response guidance. In order to ensure a thorough and informed revision of this guidance following the H1N1 2009 pandemic, a systematic review of published and unpublished economic evaluations of preparedness strategies and interventions against influenza pandemics was conducted. The search was performed in September 2011 using 10 electronic databases, 2 internet search engines, reference list screening, cited reference searching, and direct communication with relevant authors. Full and partial economic evaluations considering both costs and outcomes were included. Conversely, reviews, editorials, and studies on economic impact or complications were excluded. Studies were selected by 2 independent reviewers. 44 studies were included. Although most complied with the cost effectiveness guidelines, the quality of evidence was limited. However, the data sources used were of higher quality in economic evaluations conducted after the 2009 H1N1 pandemic. Vaccination and drug regimens were varied. Pharmaceutical plus non-pharmaceutical interventions are relatively cost effective in comparison to vaccines and/or antivirals alone. Pharmaceutical interventions vary from cost saving to high cost effectiveness ratios. According to ceiling thresholds (Gross National Income per capita), the reduction of non-essential contacts and the use of pharmaceutical prophylaxis plus the closure of schools are amongst the cost effective strategies for all countries. However, quarantine for household contacts is not cost effective even for low and middle income countries. The available evidence is generally inconclusive regarding the cost effectiveness of preparedness strategies and interventions against influenza pandemics. Studies on their effectiveness and cost effectiveness should be readily implemented in forthcoming events that

    2017-10-01

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

  13. Phenotypic plasticity in anti-intraguild predator strategies: mite larvae adjust their behaviours according to vulnerability and predation risk.

    Walzer, Andreas; Schausberger, Peter

    2013-05-01

    Interspecific threat-sensitivity allows prey to maximize the net benefit of antipredator strategies by adjusting the type and intensity of their response to the level of predation risk. This is well documented for classical prey-predator interactions but less so for intraguild predation (IGP). We examined threat-sensitivity in antipredator behaviour of larvae in a predatory mite guild sharing spider mites as prey. The guild consisted of the highly vulnerable intraguild (IG) prey and weak IG predator Phytoseiulus persimilis, the moderately vulnerable IG prey and moderate IG predator Neoseiulus californicus and the little vulnerable IG prey and strong IG predator Amblyseius andersoni. We videotaped the behaviour of the IG prey larvae of the three species in presence of either a low- or a high-risk IG predator female or predator absence and analysed time, distance, path shape and interaction parameters of predators and prey. The least vulnerable IG prey A. andersoni was insensitive to differing IGP risks but the moderately vulnerable IG prey N. californicus and the highly vulnerable IG prey P. persimilis responded in a threat-sensitive manner. Predator presence triggered threat-sensitive behavioural changes in one out of ten measured traits in N. californicus larvae but in four traits in P. persimilis larvae. Low-risk IG predator presence induced a typical escape response in P. persimilis larvae, whereas they reduced their activity in the high-risk IG predator presence. We argue that interspecific threat-sensitivity may promote co-existence of IG predators and IG prey and should be common in predator guilds with long co-evolutionary history.

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

    Since the discovery of the Groningen gas field in 1959, the Netherlands has been a key player in the European gas market. The Netherlands has built up a large onshore and offshore Exploration and Production sector, it has a highly developed gas transmission and distribution network, and is a major exporter of gas to other EU Member States. The Netherlands has considerable expertise in all parts of the gas supply chain, and is a world centre for Research and development in natural gas supply and use. More recently construction has begun on terminals to allow the import of Liquid Natural Gas to the Netherlands. However, Dutch gas reserves are now in decline, and the Netherlands will become a net importer of gas around 2025. The Dutch government wishes to capitalise on the existing industry and skills and sustain the Netherlands' place in the European gas industry beyond the life of the existing gas fields. In November 2009 the Minister of Economic Affairs published a paper describing the strategy of turning the Netherlands into a 'Gas Hub' or 'gas roundabout' for north-west Europe. The Dutch government intends that the gas hub would capitalise on the existing skills and industry, increase competition and security of supply in the Dutch gas market, create employment and make a significant contribution to the Dutch economy. The Dutch Ministry of Economic Affairs, Agriculture and Innovation has commissioned The Brattle Group to perform an analysis of the economic impact of the gas hub concept. The study has several aims including: To analyse the current contribution of the Dutch gas sector to the economy; To assess the Strengths, Weaknesses, Opportunities and Threats associated with the gas hub strategy; To quantify the benefits of the gas hub strategy to the Dutch economy. Note that the aim of the study is to define in more detail what a successful Dutch gas hub strategy would look like, to assess the strengths and weakness of the Dutch gas sector in achieving a

    Full Text Available Brazilian agricultural cooperatives have seen an unprecedented growth in production in the last decade which has led to several different product diversification strategies. Almost all studies in Brazil focus on the financial outcome of these strategies but few empirical studies have addressed them properly. Even fewer researches have dealt with the causes and possible strategies for the diversification of such cooperatives and their impact on their strategic planning. Hence, this paper aims at comprehending the different strategies in operations management for production diversification in coffee-producing cooperatives in south-eastern Brazil. This was done through a multi-case analysis comprising 6 coffee-producing cooperatives. The research analysed both verbal (through interviews and non-verbal (multi-criteria decision analysis responses to the causes of their diversification behaviours. It was possible to find out that most of the cooperatives’ rationale for diversifying is their pre-emptive response to financial crisis followed by increasing the number of associates as a strategy to overcome this economic struggle.

    Emerging pandemics threaten global health and economies and are increasing in frequency. Globally coordinated strategies to combat pandemics, similar to current strategies that address climate change, are largely adaptive, in that they attempt to reduce the impact of a pathogen after it has emerged. However, like climate change, mitigation strategies have been developed that include programs to reduce the underlying drivers of pandemics, particularly animal-to-human disease transmission. Here, we use real options economic modeling of current globally coordinated adaptation strategies for pandemic prevention. We show that they would be optimally implemented within 27 y to reduce the annual rise of emerging infectious disease events by 50% at an estimated one-time cost of approximately $343.7 billion. We then analyze World Bank data on multilateral "One Health" pandemic mitigation programs. We find that, because most pandemics have animal origins, mitigation is a more cost-effective policy than business-as-usual adaptation programs, saving between $344.0.7 billion and $360.3 billion over the next 100 y if implemented today. We conclude that globally coordinated pandemic prevention policies need to be enacted urgently to be optimally effective and that strategies to mitigate pandemics by reducing the impact of their underlying drivers are likely to be more effective than business as usual.

    Strategy and economic prospect of back-end cycle through ATW has been studied. Nuclear fuel cycle through ATW is a single stratum of back-end cycle. By ATW, volume of spent fuel which should be disposed in long term can be reduced from 70,000 MHTM to 3,000 MHTM and half-life of spent fuel can be reduced from 15,700,000 years to 300 years. Strategic values of the ATW cycle are to prevent proliferation risk and to reduce the uncertainty of long term dispose. Economic prospect of the ATW cycle will give some advantages on reducing of spent fuel volume and its disposal period, and producing electricity. (author)

    A methodology for the economic evaluation of the spent fuel and a comparative analysis of the various available strategies for its treatment, is developed. For the realization of the proposed studies a computer program METACIR was developed, which incorporates the necessary computational methodology, and it was performed a analysis of the present situation and future tendencies of the stages that constitute a PWR nuclear fuel cycle. According to the obtained results, the eternal disposal of the spent fuel is less advantageous than the reprocessing and recycle options; between the last options, the uranium recycle in PWR's is the most attractive until nearly the end of the 1990's, when the uranium and plutonium recycle in LMFBR's becomes the most convenient. The economic value of the spent fuel varies with the reactor discharge date, being considered a onus during the 1980's, and a bonus only in the next decade. (Author) [pt

    A strategy is proposed for deployment of an advanced nuclear-electric power sector that is ultimately fueled only by recycled uranium. The sector is optimized on a system basis to meet several objectives in the context of international safeguards against diversion of plutonium and proliferation of nuclear weapons. These objectives include: generation of electric power efficiently and economically; performance with utmost predictable safety; minimization of environmental impacts through conservation of natural resources, consumption of actinides and long-lived fission products, and responsible disposal of unavoidable waste; and consumption of spent fuel from currently used reactors.

    Highlights: • Cost-effectiveness of building-based storage for peak shaving has hitherto not been well understood. • Several existing storage technologies are shown to provide cost-effective peak shaving. • Setting grid demand targets rather than hard demand limits improves economics. • Accounting for seasonal demand variations in storage dispatch strategy improves economics further. • Total-energy-throughput approach is used to determine storage lifetimes. - Abstract: Meeting time-varying peak demand poses a key challenge to the U.S. electricity system. Building-based electricity storage – to enable demand response (DR) without curtailing actual appliance usage – offers potential benefits of lower electricity production cost, higher grid reliability, and more flexibility to integrate renewables. DR tariffs are currently available in the U.S. but building-based storage is still underutilized due to insufficiently understood cost-effectiveness and dispatch strategies. Whether DR schemes can yield a profit for building operators (i.e., reduction in electricity bill that exceeds levelized storage cost) and which particular storage technology yields the highest profit is yet to be answered. This study aims to evaluate the economics of providing peak shaving DR under a realistic tariff (Con Edison, New York), using a range of storage technologies (conventional and advanced batteries, flywheel, magnetic storage, pumped hydro, compressed air, and capacitors). An agent-based stochastic model is used to randomly generate appliance-level demand profiles for an average U.S. household. We first introduce a levelized storage cost model which is based on a total-energy-throughput lifetime. We then develop a storage dispatch strategy which optimizes the storage capacity and the demand limit on the grid. We find that (i) several storage technologies provide profitable DR; (ii) annual profit from such DR can range from 1% to 39% of the household’s non-DR electricity

    The majority of U.S. teens admit to handheld cellphone use while driving, an increasingly common cause of crashes. Attitudes towards novel cellphone applications and settings that block use while driving are poorly understood, potentially limiting uptake. We examined teens' willingness to reduce cellphone use while driving and perceptions of potential strategies to limit this behavior. Teen drivers (n = 153) aged 16-17 who owned smartphones and admitted to texting while driving completed an online survey. Survey instruments measured willingness to give up cellphone use and perceptions of technological and behavioral economic strategies to reduce cellphone use while driving. We used Chi-square tests to test the hypothesis that willingness to give up certain types of cellphone use while driving and the perceptions of strategies to reduce cellphone use while driving would differ by self-reported frequency of texting while driving in the past 30 days (low [1-5 days] vs. high [6 or more days]. Most teens were willing or somewhat willing to give up reading texts (90%), sending texts (95%), and social media (99%) while driving. However they were not willing to give up navigation (59%) and music applications (43%). Those who engaged in high-frequency texting while driving were more likely to say they were not willing to give up navigation applications (73% vs. 44%, P distraction (86%). The predominant reason for not wanting to use this technology was not wanting parents to monitor their behavior (60%). Promising strategies for increasing acceptance of cellphone blocking technology among teen drivers include automated screen locking and permitting hands-free navigation and music combined with behavioral economic incentives to sustain engagement.

    Full Text Available Facing the implementation of ASEAN Economic Community (AEC at the end of 2015 requires strategic measures to make Indonesia ready to compete with other nations in ASEAN. East Java Province has great potentials and contributions in the national agribusiness. Establishing agribusiness in East Java towards increased competitiveness is the right step to welcome AEC 2015. This research attempts to study the appropriate model of agribusiness development strategy for East Java. The selection of strategy model is expected to prepare a strong and competitive economy in East Java. Through three principles of data analysis model of Miles and Huberman with the emphasis on data collection, data display, and verification, this study also used a variety of data collection techniques and verifications such as Focus Group Discussion (FGD, observation, and others. This research was conducted in four regions as the focus of the study area: Probolinggo District, Sidoarjo District, Pasuruan District and the City of Batu. The results provide the following conclusions: (a the agribusiness development strategy in East Java should be done with the target approach. This means that the introduction to the target is the most important factors to determine the strategy to be implemented; (b the role of the government is highly important and strategic in developing agribusiness in East Java. These can be implemented through a variety of program models that are tailored to the target.

    Many countries are pursuing greenhouse gas (GHG) mitigation policies resulting in the increase of use of renewable sources in the electricity sector to mitigate CO 2 emissions. Nuclear energy is a non-emitting CO 2 source that could be used as part of that policy. However, its main drawback is the high investment required for its deployment. On the other hand, wind power is the clean source preferred option to mitigate CO 2 emissions. However, due to its intermittence backup power is needed, in most of the cases it must be provided with combined cycle thermal plants using natural gas. This study performs an economical comparison of a hypothetical implementation of a nuclear strategy to meet the same CO 2 emissions reduction goal that has been obtained by the actual Spaniard strategy (2005–2010) based on wind power. The investment required in both strategies is assessed under different investment scenarios and electricity production conditions for nuclear power. Also, the cost of electricity generation is compared for both strategies. - Highlights: ► Wind power electricity cost including its backup in Spain is assessed. ► Nuclear power is proposed as an alternative to produce the same CO 2 reduction. ► Nuclear power requires less installed capacity deployment. ► Investment to produce the same CO 2 reduction is smaller using nuclear power. ► Electricity generating cost is less expensive using the nuclear option

    Full Text Available In this paper authors have presented a case study of HIP Petrohemija company (Pančevo, Serbia with the aim of generating feasible strategies for technological and economic development. The research philosophy is based on the critical realism, while the research methodology is qualitative. The paper begins with the introduction to the history of HIP Petrohemija, followed by the SWOT (Strengths, Weaknesses, Opportunities, & Threats analysis, and the SWOT analysis results that were used to construct TOWS (Threats, Opportunities, Weaknesses, & Strengths matrix. This procedure generated two feasible strategies, both of which are subjected to further tests. The three portfolio models: Boston Consulting Group (BCG matrix, General Electric (GE matrix, and Nine specimen standardized strategies were used to describe the current situation of HIP Petrohemija, needed steps for the company to produce more finalized products, i.e., polymers, as well as the actions aimed at minimizing losses. This however did not provide sufficient data for determining the appropriate strategy for the company. The dilemma was solved with the help of Ansoff matrix, which showed that merging with, in its value chain, the distributor, not with to the supplier will be more profitable for the HIP Petrohemija. Contemporary Porter’s models - Five Forces and Value Chain Analysis, further confirmed the advantage of this strategy. The last model used in this paper is the Competitors Differentiation Iceberg Model that answers what the core competence of HIP Petrohemija is, with the results indicating the high quality of finalized products. Finally, the authors conclude that both strategies that were generated by the analysis are feasible - the merging with the supplier of raw material, as well as the merging with the large distributor of finalized products, with the latter being more profitable in the case of HIP Petrohemija.

    2013-10-01

    Full Text Available Traditional uneven-aged forest management seeks a balance between equilibrium stand structure and economic profitability, which often leads to harvesting strategies concentrated in the larger diameter classes. The sustainability (i.e., population persistence over time and influence of such economically optimal strategies on the equilibrium position of a stand (given by the stable diameter distribution have not been sufficiently investigated in prior forest literature. This article therefore proposes a discrete optimal control model to analyze the sustainability and stability of the economically optimal harvesting strategies of uneven-aged Pinus nigra stands. For this model, we rely on an objective function that integrates financial data of harvesting operations with a projection matrix model that can describe the population dynamics. The model solution reveals the optimal management schedules for a wide variety of scenarios. To measure the distance between the stable diameter distribution and the economically optimal harvesting strategy distribution, the model uses Keyfitz’s delta, which returns high values for all the scenarios and, thus, suggests that those economically optimal harvesting strategies have an unstabilizing influence on the equilibrium positions. Moreover, the economically optimal harvesting strategies were unsustainable for all the scenarios.

    Full Text Available This paper discusses the efforts and actions by the Kenyan government to address challenges of agrarian change and rural transformation in Keiyo. The paper demonstrates that state employs the mechanisms of co-opting the forces of rural commercialization through the strategies of land consolidation. The paper explains that these strategies widen the scope of engagement in the Keiyo households in Kenya today. Keiyo households have demonstrated their capacity to respond positively and spontaneously to agrarian changes and innovations which proves vital to the enhancement of their economic well-being. The paper employs data collected from the three ecological zones, in order to examine the characteristics of households in Keiyo. It is demonstrated that the characteristics of these households reflect the different economic opportunity structures of the three areas. It is suggested that while the distribution of resources within any of the three ecological zones is to varying degrees unequal, there is nevertheless a pronounced pattern of inequality across eco-zones: most households in the highland are better endowed with resources than most households either on the escarpment or in the valley.

    Influenza pandemics present a global threat owing to their potential mortality and substantial economic impacts. Stockpiling antiviral drugs to manage a pandemic is an effective strategy to offset their negative impacts; however, little is known about the long-term optimal size of the stockpile under uncertainty and the characteristics of different countries. Using an epidemic-economic model we studied the effect on total mortality and costs of antiviral stockpile sizes for Brazil, China, Guatemala, India, Indonesia, New Zealand, Singapore, the UK, the USA and Zimbabwe. In the model, antivirals stockpiling considerably reduced mortality. There was greater potential avoidance of expected costs in the higher resourced countries (e.g. from $55 billion to $27 billion over a 30 year time horizon for the USA) and large avoidance of fatalities in those less resourced (e.g. from 11.4 to 2.3 million in Indonesia). Under perfect allocation, higher resourced countries should aim to store antiviral stockpiles able to cover at least 15 per cent of their population, rising to 25 per cent with 30 per cent misallocation, to minimize fatalities and economic costs. Stockpiling is estimated not to be cost-effective for two-thirds of the world's population under current antivirals pricing. Lower prices and international cooperation are necessary to make the life-saving potential of antivirals cost-effective in resource-limited countries.

    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.

    A number of strategies exist to reduce Clostridium difficile (C. difficile) transmission. We conducted an economic evaluation of "bundling" these strategies together. We constructed an agent-based computer simulation of nosocomial C. difficile transmission and infection in a hospital setting. This model included the following components: interactions between patients and health care workers; room contamination via C. difficile shedding; C. difficile hand carriage and removal via hand hygiene; patient acquisition of C. difficile via contact with contaminated rooms or health care workers; and patient antimicrobial use. Six interventions were introduced alone and "bundled" together: (a) aggressive C. difficile testing; (b) empiric isolation and treatment of symptomatic patients; (c) improved adherence to hand hygiene and (d) contact precautions; (e) improved use of soap and water for hand hygiene; and (f) improved environmental cleaning. Our analysis compared these interventions using values representing 3 different scenarios: (1) base-case (BASE) values that reflect typical hospital practice, (2) intervention (INT) values that represent implementation of hospital-wide efforts to reduce C. diff transmission, and (3) optimal (OPT) values representing the highest expected results from strong adherence to the interventions. Cost parameters for each intervention were obtained from published literature. We performed our analyses assuming low, normal, and high C. difficile importation prevalence and transmissibility of C. difficile. INT levels of the "bundled" intervention were cost-effective at a willingness-to-pay threshold of $100,000/quality-adjusted life-year in all importation prevalence and transmissibility scenarios. OPT levels of intervention were cost-effective for normal and high importation prevalence and transmissibility scenarios.

    Highlights: • Economics analysis of fuel cycle cost of FFHRs is carried out. • The mass flows of different fuel cycle strategies are established based on the equilibrium fuel cycle model. • The levelized fuel cycle costs of different fuel cycle strategies are calculated, and compared with current once-through fuel cycle. - Abstract: The economics analysis of fuel cycle cost of fusion–fission hybrid reactors has been performed to compare four fuel cycle strategies: light water cooled blanket burning natural uranium (Strategy A) or spent nuclear fuel (Strategy B), sodium cooled blanket burning transuranics (Strategy C) or minor actinides (Strategy D). The levelized fuel cycle costs (LFCC) which does not include the capital cost, operation and maintenance cost have been calculated based on the equilibrium mass flows. The current once-through (OT) cycle strategy has also been analyzed to serve as the reference fuel cycle for comparisons. It is found that Strategy A and Strategy B have lower LFCCs than OT cycle; although the LFCC of Strategy C is higher than that of OT cycle when the uranium price is at its nominal value, it would become comparable to that of OT cycle when the uranium price reaches its historical peak value level; Strategy D shows the highest LFCC, because it needs to reprocess huge mass of spent nuclear fuel; LFCC is sensitive to the discharge burnup of the nuclear fuel.

    The tsunami of December 2004 impacted large areas of Thailand's coastline and caused severe human and economic losses. The recovery period revealed differences in the vulnerabilities of communities affected. An understanding of the causal factors of vulnerability is crucial for minimising the negative effects of future threats and developing adaptive capacities. This paper analyses the vulnerabilities and the development of adaptation strategies in the booming tourist area of Khao Lak and in the predominantly fishing and agricultural area of Ban Nam Khem through a comprehensive vulnerability framework. The results show that social networks played a crucial role in coping with the disaster. Social cohesion is important for strengthening the community and developing successful adaptation strategies. The development of tourism and the turning away from traditional activities have a significant positive influence on the income situation, but create a dependency on a single business sector. It could be shown that households generating their income in the tourism sector were vulnerable unless they had diversified their income previously. Income diversification decreased the vulnerability in the study areas. Adaptation strategies and processes developed in the aftermath clearly address these issues.

    Full Text Available The paper proposes an economic assessment of paternalism by comparing different alternative responses to dynamically inconsistent behaviors consecutive to hyperbolic discounting. Two main types of action are possible, self-commanding strategies and paternalism The first category includes personal rules and pre-commitment The second can be subcategorized between coercive and non-coercive forms of paternalism, which are respectively associated (although it is debatable with legal paternalism and with ‘nudges’. Despite being self-inflicted, self-commanding strategies are actually not cost free and can result in a dramatic cutback of people’s freedom of choice. Likewise, legal paternalism can, on occasion, be less harmful than personal rules or pre-commitment; similarly, nudges can be more invasive and less effective than their proponents want us to believe. The aim of this paper is not to propose any standardized form of response to irrational behavior (whatever that may mean but to argue, on the contrary, that every case should be individually appraised. Individual situations can be remedied by self-commanding strategies or by paternalistic policies, either in isolation or in combination.

    Full Text Available The European Legislation is very strict regarding the importance of reducing the energy consumption in buildings sector. The importance of achieving nearly zero energy consumption levels for both new and existing buildings is also highlighted in each Members’ national legislation. Moreover, the high percentage of existing buildings across European Union, indicates that they need to be adequately approached in order to achieve the ambitious energy efficiency goals. This implies creating the optimal technical and financial retrofit strategies regarding minimizing the energy consumption without lowering the interior comfort levels. In Romania, there is no unitary strategy aiming to maximize the energy efficiency in buildings which also takes into consideration the financial part of the process. Moreover, there are no known national guidelines and strategies for buildings retrofit which takes into consideration a wide range of equipment. The Romanian Energy Efficiency Strategy presents few possibilities resulted from integrating renewable energy sources within typical Romanian buildings, while the Buildings Performance Institute Europe conducted a research regarding the potential of nearly Zero Energy Buildings implementation across Romanian territory. Both studies refer only to typical buildings and do not present a large perspective for retrofitting action, while the financial study is not properly presented. Thus, this paper develops a comprehensive financial study which could be used as guideline by stakeholders, in order to find the best technical solution for decreasing the final energy consumption in Romanian residential buildings. Using the RETScreen software and its economical features, there were developed several energy efficiency solutions, and by analyzing the financial benefits implied, the best solution was chosen. By adopting the solutions presented within this feasibility study, the energy consumption of buildings should be

    To examine the feasibility of implementing nine behavioural economics-informed strategies, or 'nudges', that aimed to encourage home dinner vegetable intake among low-income children. Caregivers were assigned six of nine strategies and implemented one new strategy per week (i.e. 6 weeks) during three dinner meals. Caregivers recorded child dinner vegetable intake on the nights of strategy implementation and rated the level of difficulty for assigned strategies. Baseline data on home vegetable availability and child vegetable liking were collected to assess overall strategy feasibility. Participants' homes in a large Midwestern metropolitan area, USA. Low-income caregiver/child (aged 9-12 years) dyads (n 39). Pairwise comparisons showed that child dinner vegetable intake for the strategy 'Serve at least two vegetables with dinner meals' was greater than intake for each of two other strategies: 'Pair vegetables with other foods the child likes' and 'Eat dinner together with an adult(s) modelling vegetable consumption'. Overall, caregivers' mean rating of difficulty for implementing strategies was 2·6 (1='not difficult', 10='very difficult'). Households had a mean of ten different types of vegetables available. Children reported a rating ≥5 for seventeen types of vegetable on a labelled hedonic scale (1='hate it', 5-6='it's okay', 10='like it a lot'). Behavioural economics-informed strategies are feasible to implement during dinner meals, with some strategies differing by how much they influence vegetable intake among low-income children in the home.

    This paper presents an evaluation of the potential energy savings from adding advanced control to existing packaged air conditioners. Advanced control options include air-side economizer, multi-speed fan control, demand control ventilation and staged cooling. The energy and cost savings from the different control strategies individually and in combination are estimated using the EnergyPlus detailed energy simulation program for four building types, namely, a small office building, a stand-alone retail building, a strip mall building and a supermarket building. For each of the four building types, the simulation was run for 16 locations covering all 15 climate zones in the U.S. The maximum installed cost of a replacement controller that provides acceptable payback periods to owners is estimated.

    The benefit of high-dose chemotherapy (HDC) has not been clearly demonstrated. It may offer disease-free survival improvement at the expense of major toxicity and increasing cost. We evaluated the trade-offs between toxicity, relapse, and costs using a quality-adjusted time without symptoms or toxicity (Q-TWiST) analysis. The analysis was conducted in the context of a randomized trial (PEGASE 01) evaluating the benefit of HDC for 314 patients with high-risk breast cancer. A Q-TWiST analysis was first performed to compare HDC with standard chemotherapy. We then used the results of this Q-TWiST analysis to inform a cost per quality-adjusted life-year (QALY) comparison between treatments. Q-TWiST durations were in favor of HDC, whatever the weighting coefficients used for the analysis. This benefit was significant when the weighting coefficient related to the time spent after relapse was low (0.78), HDC offered no benefit. For intermediate values, the results depended on the weighting coefficient attributed to the toxicity period. The incremental cost per QALY ranged from 12,691euro/QALY to 26,439euro/QALY, according to the coefficients used to weight toxicity and relapse. The benefits of HDC outweigh the burdens of treatment for a wide range of utility coefficients. Economic impact is not a barrier to HDC diffusion in this situation. Nevertheless, no significant benefit was demonstrated for a certain range of utility values.

    Full Text Available The article develops an economic and ecological model of optimal management of the system of solid waste disposal at the regional level, identifies its target functions and forms optimisation scenarios of management of this sphere with theoretically optimal parameters’ values. Based on the model of management of the sphere of solid waste disposal the article forms an algorithm of identification of optimal managerial strategies and mechanisms of their realisation, which allows solution of the set tasks of optimisation of development of the sphere of solid waste disposal at a given set of values and parameters of the state of the system for a specific type of life cycle of solid waste and different subjects of this sphere. The developed model has a number of feasible solutions and, consequently, offers selection of the best of them with consideration of target functions. The article conducts a SWOT analysis of the current state of solid waste disposal in the Poltava region and identifies a necessity of development of a relevant strategy on the basis of the developed economic and ecological model with consideration of optimisation of mutually opposite criteria: ecological risk for the population from the sphere of solid waste disposal and total expenditures for this sphere functioning. The article conducts modelling of this situation by basic (current situation and alternative scenarios and finds out that, at this stage, it is most expedient to build in the region four sorting lines and five regional solid waste grounds, while expenditures on this sphere are UAH 62.0 million per year, income from secondary raw material sales – UAH 71.2 per year and reduction of the ecological risk – UAH 13 million per year.

    Essentials Correct duration of treatment after a first unprovoked venous thromboembolism (VTE) is unknown. We assessed when restarting anticoagulation was worthwhile based on patient risk of recurrent VTE. When the risk over a one-year period is 17.5%, restarting is cost-effective. However, sensitivity analyses indicate large uncertainty in the estimates. Background Following at least 3 months of anticoagulation therapy after a first unprovoked venous thromboembolism (VTE), there is uncertainty about the duration of therapy. Further anticoagulation therapy reduces the risk of having a potentially fatal recurrent VTE but at the expense of a higher risk of bleeding, which can also be fatal. Objective An economic evaluation sought to estimate the long-term cost-effectiveness of using a decision rule for restarting anticoagulation therapy vs. no extension of therapy in patients based on their risk of a further unprovoked VTE. Methods A Markov patient-level simulation model was developed, which adopted a lifetime time horizon with monthly time cycles and was from a UK National Health Service (NHS)/Personal Social Services (PSS) perspective. Results Base-case model results suggest that treating patients with a predicted 1 year VTE risk of 17.5% or higher may be cost-effective if decision makers are willing to pay up to £20 000 per quality adjusted life year (QALY) gained. However, probabilistic sensitivity analysis shows that the model was highly sensitive to overall parameter uncertainty and caution is warranted in selecting the optimal decision rule on cost-effectiveness grounds. Univariate sensitivity analyses indicate variables such as anticoagulation therapy disutility and mortality risks were very influential in driving model results. Conclusion This represents the first economic model to consider the use of a decision rule for restarting therapy for unprovoked VTE patients. Better data are required to predict long-term bleeding risks during therapy in this

    Transnational tobacco companies (TTCs) have used varied strategies to access previously closed markets. Using TTCs’ efforts to enter the South Korean market from the late 1980s as a case study, this article asks whether there are common patterns in these strategies that relate to the broader economic development models adopted by targeted countries. An analytical review of the existing literature on TTCs’ efforts to access emerging markets was conducted to develop hypotheses relating TTCs’ strategies to countries’ economic development models. A case study of Korea was then undertaken based on analysis of internal tobacco industry documents. Findings were consistent with the hypothesis that TTCs’ strategies in Korea were linked to Korea’s export-oriented economic development model and its hostile attitude toward foreign investment. A fuller understanding of TTCs’ strategies for expansion globally can be derived by locating them within the economic development models of specific countries or regions. Of foremost importance is the need for governments to carefully balance economic and public health policies when considering liberalisation. PMID:23327486

    The United States commercial nuclear power industry is nearly forty years old. Soon after the turn of the century, the United States expects to see a significant rise in the number of plants requiring decommissioning. This, coupled with recent economic pressures which are impacting the U.S. electrical generation industry and have resulted in the premature shutdown of some nuclear power plants, heighten the need for clear regulations and standards addressing facility closure and decommissioning. Since the issue of decommissioning involves public health and safety, technical, environmental and financial aspects, this complex regulatory environment poses a major challenge to the industry in this area. There are three fundamental issues facing utilities as they develop strategies for the eventual decommissioning of their nuclear power plants. These issues are the regulatory approach to decommissioning, the question of the availability of adequate funding, including the uncertainty resulting from the uncertainty of waste disposal options, and the need to meet environmental standards for the protection of health and safety. Futhermore, these issues, in particular the economic-related issues, are magnified in the event of prematurely shut down nuclear power plant. (Author)

    Globalization phenomena and Information Communication Technology (ICT) are producing deep changes worldwide. The economic environment and society where firms both cooperate and compete with each other are rapidly changing leading firms towards recognizing the role of intangible resources as a source of fresh competitive advantage. Experience, innovation and the ability to create new knowledge completely arise from the act of human resources inviting firms to focus on how to generate and shape knowledge. Therefore, the future of firms depends greatly on how managers are able to explore and exploit human resources. However, without a clear understanding of the nature of human beings and the complexity behind human interactions, we cannot understand the theory of organizational knowledge creation. Thus, how can firms discover, manage and valorize this "human advantage"? Neuroscience can increase the understanding of how cognitive and emotional processes work; in doing so, we may be able to better understand how individuals involved in a business organization make decisions and how external factors influence their behavior, especially in terms of commitment activation and engagement level. In this respect, a neuroscientific approach to business can support managers in decision-making processes. In a scenario where economic humanism plays a central role in the process of fostering firms' competitiveness and emerging strategies, we believe that a neuroscience approach in a business organization could be a valid source of value and inspiration for manager decision-making processes.

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

    To assess the return on investment (ROI) and economic impact of providing insurance coverage for the laparoscopic adjustable gastric banding (LAGB) procedure in classes II and III obese members of the Texas Employees Retirement System (ERS) and their dependents from payer, employer, and societal perspectives. Classes II and III obese employee members and their adult dependents were identified in a Texas ERS database using self-reported health risk assessment (HRA) data. Direct health costs and related absenteeism and mortality losses were estimated using data from previous research. A dynamic input-output model was then used to calculate overall economic effects by incorporating direct, indirect, and induced impacts. Direct health costs were inflation-adjusted to 2008 US dollars using the Consumer Price Index for Medical Care and other spending categories were similarly adjusted using relevant consumer and industrial indices. The future cost savings and other monetary benefits were discounted to present value using a real rate of 4.00%. From the payer perspective (ERS), the payback period for direct health costs associated with the LAGB procedure was 23-24 months and the annual return (over 5 years) was 28.8%. From the employer perspective (State of Texas), the costs associated with the LAGB procedure were recouped within 17-19 months (in terms of direct, indirect, and induced gains as they translated into State revenue) and the annual return (over 5 years) was 45.5%. From a societal perspective, the impact on total business activity for Texas (over 5 years) included gains of $195.3 million in total expenditures, $93.8 million in gross product, and 1354 person-years of employment. The analysis was limited by the following: reliance on other studies for methodology and use of a control sample; restriction of cost savings to 2.5 years which required out-of-sample forecasting; conservative assumptions related to the cost of the procedure; exclusion of presenteeism

    Contingent valuation is widely used to determine individuals' willingness to pay (WTP) for a health gain. Our study aimed to elicit an empirical estimate of the monetary value of a quality-adjusted life year (QALY) in a Greek outpatient setting in times of economic austerity and assess the impact of patients' characteristics on their valuations. We used a questionnaire as a survey tool to determine the maximum WTP for a health gain of a hypothetical therapy and to evaluate patients' health-related quality of life (EuroQoL-5D-3L) and demographic and socioeconomic characteristics. EuroQoL tariffs were used to estimate health utilities. Mean WTP values were computed and ordinary least squares regressions performed on transformed Box-Cox and logarithmic dependent WTP per QALY variables to remedy observed skewness problems. Analyses were performed for 167 patients with utility values less than unity. Mean WTP per QALY reported was similar for both payment vehicles examined: payments made out-of-pocket (€2629) and payments made through new tax imposition (€2407). Regression results showed that higher net monthly family income was associated with higher WTP per QALY for both payment vehicles. Moreover, the presence of a chronic condition and higher level of education were associated with higher out-of-pocket WTP per QALY and WTP per QALY through taxes, respectively. The very low WTP per QALY estimates could be explained by the recent severe economic depression and austerity in Greece. In fact, family income was found to be a significant predictor of WTP per QALY. Since these estimates deviate significantly from the cost-effectiveness thresholds still employed in economic evaluations in this country, research should be undertaken promptly to further examine this important issue using a nationwide representative sample of the general population along with WTP and other methodologies.

However, nearly 90% of public cord blood banks have declared that they are struggling to maintain their financial sustainability and avoid bankruptcy. The objective of this study is to evaluate how characteristics of cord blood units influence their utilization, then use this information to model the economic viability and therapeutic value of different banking strategies. Methods Retrospective analysis of cord blood data registered between January 1st, 2009 and December 31st, 2011 in Bone Marrow Donor Worldwide. Data were collected from four public banks in France, Germany and the USA. Samples were eligible for inclusion in the analysis if data on cord blood and maternal HLA typing and biological characteristics after processing were available (total nucleated and CD34+ cell counts). 9,396 banked cord blood units were analyzed, of which 5,815 were Caucasian in origin. A multivariate logistic regression model assessed the influence of three parameters on the CBU utilization rate: ethnic background, total nucleated and CD34+ cell counts. From this model, we elaborated a Utilization Score reflecting the probability of transplantation for each cord blood unit. We stratified three Utilization Score thresholds representing four different banking strategies, from the least selective (scenario A) to the most selective (scenario D). We measured the cost-effectiveness ratio for each strategy by comparing performance in terms of number of transplanted cord blood units and level of financial deficit. Results When comparing inputs and outputs over three years, Scenario A represented the most extreme case as it delivered the highest therapeutic value for patients (284 CBUs transplanted) along with the highest financial deficit (USD 5.89 million). We found that scenario C resulted in 219 CBUs transplanted with a limited deficit (USD 0.98 million) that charities and public health could realistically finance over the long

    2013-01-01

    Background The threat of emergence of a human-to-human transmissible strain of highly pathogenic influenza A(H5N1) is very real, and is reinforced by recent results showing that genetically modified A(H5N1) may be readily transmitted between ferrets. Public health authorities are hesitant in introducing social distancing interventions due to societal disruption and productivity losses. This study estimates the effectiveness and total cost (from a societal perspective, with a lifespan time horizon) of a comprehensive range of social distancing and antiviral drug strategies, under a range of pandemic severity categories. Methods An economic analysis was conducted using a simulation model of a community of ~30,000 in Australia. Data from the 2009 pandemic was used to derive relationships between the Case Fatality Rate (CFR) and hospitalization rates for each of five pandemic severity categories, with CFR ranging from 0.1% to 2.5%. Results For a pandemic with basic reproduction number R0 = 1.8, adopting no interventions resulted in total costs ranging from $441 per person for a pandemic at category 1 (CFR 0.1%) to $8,550 per person at category 5 (CFR 2.5%). For severe pandemics of category 3 (CFR 0.75%) and greater, a strategy combining antiviral treatment and prophylaxis, extended school closure and community contact reduction resulted in the lowest total cost of any strategy, costing $1,584 per person at category 5. This strategy was highly effective, reducing the attack rate to 5%. With low severity pandemics costs are dominated by productivity losses due to illness and social distancing interventions, whereas higher severity pandemic costs are dominated by healthcare costs and costs arising from productivity losses due to death. Conclusions For pandemics in high severity categories the strategies with the lowest total cost to society involve rigorous, sustained social distancing, which are considered unacceptable for low severity pandemics due to societal

    Clostridium difficile infection (CDI) is the most common cause of infectious diarrhea in health care settings, and for patients presumed to have CDI, their isolation while awaiting laboratory results is costly. Newer rapid tests for CDI may reduce this burden, but the economic consequences of different testing algorithms remain unexplored. We used decision analysis from the hospital perspective to compare multiple CDI testing algorithms for adult inpatients with suspected CDI, assuming patient management according to laboratory results. CDI testing strategies included combinations of on-demand PCR (odPCR), batch PCR, lateral-flow diagnostics, plate-reader enzyme immunoassay, and direct tissue culture cytotoxicity. In the reference scenario, algorithms incorporating rapid testing were cost-effective relative to nonrapid algorithms. For every 10,000 symptomatic adults, relative to a strategy of treating nobody, lateral-flow glutamate dehydrogenase (GDH)/odPCR generated 831 true-positive results and cost $1,600 per additional true-positive case treated. Stand-alone odPCR was more effective and more expensive, identifying 174 additional true-positive cases at $6,900 per additional case treated. All other testing strategies were dominated by (i.e., more costly and less effective than) stand-alone odPCR or odPCR preceded by lateral-flow screening. A cost-benefit analysis (including estimated costs of missed cases) favored stand-alone odPCR in most settings but favored odPCR preceded by lateral-flow testing if a missed CDI case resulted in less than $5,000 of extended hospital stay costs and 93%, or if the symptomatic carrier proportion among the toxigenic culture-positive cases was >80%. These results can aid guideline developers and laboratory directors who are considering rapid testing algorithms for diagnosing CDI. PMID:24478478

    Clostridium difficile infection (CDI) is the most common cause of infectious diarrhea in health care settings, and for patients presumed to have CDI, their isolation while awaiting laboratory results is costly. Newer rapid tests for CDI may reduce this burden, but the economic consequences of different testing algorithms remain unexplored. We used decision analysis from the hospital perspective to compare multiple CDI testing algorithms for adult inpatients with suspected CDI, assuming patient management according to laboratory results. CDI testing strategies included combinations of on-demand PCR (odPCR), batch PCR, lateral-flow diagnostics, plate-reader enzyme immunoassay, and direct tissue culture cytotoxicity. In the reference scenario, algorithms incorporating rapid testing were cost-effective relative to nonrapid algorithms. For every 10,000 symptomatic adults, relative to a strategy of treating nobody, lateral-flow glutamate dehydrogenase (GDH)/odPCR generated 831 true-positive results and cost $1,600 per additional true-positive case treated. Stand-alone odPCR was more effective and more expensive, identifying 174 additional true-positive cases at $6,900 per additional case treated. All other testing strategies were dominated by (i.e., more costly and less effective than) stand-alone odPCR or odPCR preceded by lateral-flow screening.

    and control as alternative strategies. China has for years held high the goal of "basic elimination", eradication by another name, in sensible semi-defiance of WHO dictates. The Chinese experience makes it clear that, given community organization, exhaustive attention to case detection, management and focus elimination, plus the political will at all levels of society, it is possible both to eliminate malaria from large areas of an expansive nation and to implement surveillance necessary to maintain something approaching eradication status in those areas. But China has not succeeded in the international border regions of the tropical south where unfettered population movement confounds the program. Thailand, Malaysia and to an extent Vietnam have also reached essential elimination in their rice field plains by vigorous vertical programs but fall short at their forested borders. Economics is central to the history of the rise and fall of nations, and to the history of disease in the people who constitute nations. The current love affair with free market economics as the main driving force for advance of national wealth puts severe limitations on the essential involvement of communities in malaria management. The task of malaria control or elimination needs to be clearly related to the basic macroeconomic process that preoccupies governments, not cloistered away in the health sector Historically malaria has had a severe, measurable, negative impact on the productivity of nations. Economic models need rehoning with political aplomb and integrating with technical and demographic strategies. Recent decades in Chinese malaria history carry some lessons that may be relevant in this context.

    Over recent years, public involvement in health research has expanded considerably. However, public involvement in designing and conducting health economics research is seldom reported. Here we describe the development, delivery and assessment of an approach for involving people in a clearly defined piece of health economics research: selecting health states for valuation in estimating quality-adjusted life-years (QALYs). This involvement formed part of a study to develop a condition-specific preference-based measure of health-related quality of life, the Multiple Sclerosis Impact Scale (MSIS-8D), and the work reported here relates to the identification of plausible, or realistic, health states for valuation. An Expert Panel of three people with multiple sclerosis (MS) was recruited from a local involvement network, and two health economists designed an interactive task that enabled the Panel to identify health states that were implausible, or unlikely to be experienced. Following some initial confusion over terminology, which was resolved by discussion with the Panel, the task worked well and can be adapted to select health states for valuation in the development of any preference-based measure. As part of the involvement process, five themes were identified by the Panel members and the researchers which summarised our experiences of public involvement in this health economics research example: proportionality, task design, prior involvement, protectiveness and partnerships. These are described in the paper, along with their practical implications for involving members of the public in health economics research. Our experience demonstrates how members of the public and health economists can work together to improve the validity of health economics research. Plain Language Summary It has become commonplace to involve members of the public in health service research. However, published reports of involving people in designing health economics research are rare. We

    To conduct an economic evaluation of the three commonly used interventions that reduce sexual HIV transmission when an HIV-negative female aims to conceive with an HIV-positive male on combination antiretroviral therapy (condomless sex restricted to timed ovulation [CS], sperm washing with intrauterine insemination [SW] and condomless sex restricted to timed ovulation with pre-exposure prophylaxis [CS-PrEP]). As SW and CS-PrEP are only privately available for pregnancy planning for this population in Canada, this study was conducted to inform policy decisions concerning potential public health insurance coverage, as well as to inform fertility counselling in settings with adequate combination antiretroviral therapy access globally. We developed a cohort Markov model with a lifetime horizon and used the perspective of Ontario's Ministry of Health (MOH). Input parameters were drawn from literature, the MOH's Schedule of Benefits and a time trade-off questionnaire designed for this study. Outcome measures included quality-adjusted life-years and incremental cost-effectiveness. Costs and benefits were discounted at annual rates of 3%. Costs were reported in Canadian 2013 dollars and an exchange rate of 1 USD to 1.066 CND was applied where necessary. Sensitivity analysis assessed the uncertainty of model parameters. The base case analysis found that CS-PrEP and SW were each more costly and less effective at conception than CS. The results were robust in the sensitivity analysis and suggest that CS is the dominant conception strategy in this population. Neither CS-PrEP nor SW represent better value for money relative to CS as a conception option for HIV-discordant couples with positive male partners. Based on these findings, CS-PrEP and SW cannot be recommended for public-funding in developed countries.

    Hydrophytes generally exhibit highly acquisitive leaf economics. However, a range of growth forms is evident, from small, free-floating and rapidly growing Lemniden to large, broad-leaved Nymphaeiden, denoting variability in adaptive strategies. Traits used to classify adaptive strategies in terrestrial species, such as canopy height, are not applicable to hydrophytes. We hypothesize that hydrophyte leaf size traits and economics exhibit sufficient overlap with terrestrial species to allow a common classification of plant functional types, sensu Grime's CSR theory. Leaf morpho-functional traits were measured for 61 species from 47 water bodies in lowland continental, sub-alpine and alpine bioclimatic zones in southern Europe and compared against the full leaf economics spectrum and leaf size range of terrestrial herbs, and between hydrophyte growth forms. Hydrophytes differed in the ranges and mean values of traits compared with herbs, but principal components analysis (PCA) demonstrated that both groups shared axes of trait variability: PCA1 encompassed size variation (area and mass), and PCA2 ranged from relatively dense, carbon-rich leaves to nitrogen-rich leaves of high specific leaf area (SLA). Most growth forms exhibited trait syndromes directly equivalent to herbs classified as R adapted, although Nymphaeiden ranged between C and SR adaptation. Our findings support the hypothesis that hydrophyte adaptive strategy variation reflects fundamental trade-offs in economics and size that govern all plants, and that hydrophyte adaptive strategies can be directly compared with terrestrial species by combining leaf economics and size traits.

    Full Text Available Abstract The aim of this study was to verify whether patients with Parkinson's disease (PD are able to adjust their motor behavior according to restrictions imposed by the task instruction during walking with obstacle crossing. Eighteen elderly people (moderate motor compromise with a diagnosis of PD walked on a pathway and cross an obstacle according to the following conditions: walking at preferred velocity; walking at maximum vertical elevation of the feet to cross the obstacle; walking at maximum step length to cross the obstacle; walking at maximum velocity. The modulations were directly related to the instructions provided to patients with PD before performing each task, which seems to indicate that attentional cues can influence and benefit strategies during obstacle crossing. In conclusion, patients with PD are able to adjust walking during obstacle crossing according to instructions given to them, which increases their safety.

    The social, political and economic reforms of 1992 in Russia led to a decade of rising income inequality, unemployment and economic crises, the most severe of which occurred in 1998. This study assesses dietary trends for children in low and high income households during this politically and economically unstable period from 1994 to 2000. Several possible food-related behaviors were also assessed to evaluate coping strategies adopted in the face of decreasing economic stability. Low income children maintained a steady energy intake per kilogram weight throughout the study period (251.0-259.4 kJ/kg), whereas intake for high income children increased significantly to a per capital average of 297.1 kJ/kg by 2000. At the food group level, the trend in per capita intake for all food groups was maintained for low income children except for a 22% decrease in meat and poultry consumption (P economic crisis.

    Based on the current and prospected share of nuclear power in the national energy supply strategy an optimal programme is developed for exploitation of plutonium in both light water and fast reactor systems. Assuming cost trends until and beyond the year 2000 for uranium, plutonium, uranium enrichment, fuel fabricaton and assessing the availability of plutonium from the domestic power plants and from abroad the nuclear construction programme is optimized economically in view of the estimated development in the investment costs of various plant types. Given the expected nuclear share of the energy procurement this sector is covered by the alternative production schemes, i.e. light water reactors with and without plutonium recycle and fast reactors. The plant sizes are allowed to be either 500 MWe or 1000 MWe. The installation dates are fixed manually with a minor flexibility of time but with all the three degrees of freedom in the plant types. Defining the objective function in terms of minimized revenue requirement in plant amortization and operation the generated scenarios are screened off and they finally converge to the optimal policy of nuclear power construction up to the year 2000. Special attention is placed on the constraints which eliminate excessive proliferation of reactor types. This is mainly implemented by the criterion of increasing the domestic share in the investments. The established technology is associated with a larger share of the Finnish manufacturing and the introduction of new fuel or reactor type is taken to correspond to a reduced domestic investment share. The results yield the time schedule and installed capacity of the three different production means. Due to the uncertainties prevailing in the forecasts sensitivity studies are performed as functions of the major economic parameters and their temporal development

    The economic implications from the US Medicare perspective of adopting alternative treatment strategies for acute bacterial skin and skin structure infections (ABSSSIs) are substantial. The objective of this study is to describe a modeling framework that explores the impact of decisions related to both the location of care and switching to different antibiotics at discharge. A discrete event simulation (DES) was developed to model the treatment pathway of each patient through various locations (emergency department [ED], inpatient, and outpatient) and the treatments prescribed (empiric antibiotic, switching to a different antibiotic at discharge, or a second antibiotic). Costs are reported in 2012 USD. The mean number of days on antibiotic in a cohort assigned to a full course of vancomycin was 11.2 days, with 64% of the treatment course being administered in the outpatient setting. Mean total costs per patient were $8671, with inpatient care accounting for 58% of the costs accrued. The majority of outpatient costs were associated with parenteral administration rather than drug acquisition or monitoring. Scenarios modifying the treatment pathway to increase the proportion of patients receiving the first dose in the ED, and then managing them in the outpatient setting or prescribing an oral antibiotic at discharge to avoid the cost associated with administering parenteral therapy, therefore have a major impact and lower the typical cost per patient by 11-20%. Since vancomycin is commonly used as empiric therapy in clinical practice, based on these analyses, a shift in treatment practice could result in substantial savings from the Medicare perspective. The choice of antibiotic and location of care influence the costs and resource use associated with the management of ABSSSIs. The DES framework presented here can provide insight into the potential economic implications of decisions that modify the treatment pathway.

In the investment costs the domestic fraction is regarded competitive up to a certain marginal excess. Plutonium recycle is seen to be competitive from 1985 or as soon as the required amount of fuel has been reprocessed. The domestic accumulation of plutonium will be able to support the introduction of the LMFBR in 1997.

    HVAC systems and associated equipment consume a relatively large fraction of total building energy consumption, a significant portion of which is attributed to fan operation. The operation of economizer dampers when installed can cause high energy consumption in fans if they are not functioning in proper and optimal manner. This will mainly be due to the potential high pressure drops through those dampers and associated high total pressures that should be developed by supply and/or return fans. It is then necessary to ensure that a proper strategy to operate optimally the economizer dampers is implemented with minimum fan energy use. The paper examines several operation strategies of the economizer dampers and investigates their effects on the performance of both the supply and return fans in HVAC system. It also discusses a new operating strategy for economizer dampers that can lead to lower fan energy use. The strategies are evaluated by simulations for a typically existing HVAC system. Several factors such as the building locations, system characteristics, resistance in the duct where the dampers are installed, supply air temperature and economizer control, and minimum ventilation requirements are also considered during the evaluations. The results show that the way of the economizer dampers been controlled has a significant effect on fan performance and its energy use. The proposed strategy if properly implemented can provide fan energy saving in the range of 5-30%, depending mainly on the number of hours when the system operates in the free cooling mode, damper characteristics, and minimum outdoor air.

  14. Does investment in leaf defenses drive changes in leaf economic strategy? A focus on whole-plant ontogeny.

    2015-04-01

    Leaf defenses have long been studied in the context of plant growth rate, resource availability, and optimal investment theory. Likewise, one of the central modern paradigms of plant ecophysiology, the leaf economics spectrum (LES), has been extensively studied in the context of these factors across ecological scales ranging from global species data sets to temporal shifts within individuals. Despite strong physiological links between LES strategy and leaf defenses in structure, function, and resource investment, the relationship between these trait classes has not been well explored. This study investigates the relationship between leaf defenses and LES strategy across whole-plant ontogeny in three diverse Helianthus species known to exhibit dramatic ontogenetic shifts in LES strategy, focusing primarily on physical and quantitative chemical defenses. Plants were grown under controlled environmental conditions and sampled for LES and defense traits at four ontogenetic stages. Defenses were found to shift strongly with ontogeny, and to correlate strongly with LES strategy. More advanced ontogenetic stages with more conservative LES strategy leaves had higher tannin activity and toughness in all species, and higher leaf dry matter content in two of three species. Modeling results in two species support the conclusion that changes in defenses drive changes in LES strategy through ontogeny, and in one species that changes in defenses and LES strategy are likely independently driven by ontogeny. Results of this study support the hypothesis that leaf-level allocation to defenses might be an important determinant of leaf economic traits, where high investment in defenses drives a conservative LES strategy.

    Securing energy demand for next generations is one of the most challenges aspects facing any sustained development plans, due to the growing electric energy demand and Egypt as a country of limited fossil fuel resources has to diversify its energy portfolio by utilization of its renewable energy resources, mainly wind due to its economic potential and solar as proved by Egypt's wind and solar atlases. In the year 2009/2010, the total installed capacity in Egypt was 24726 MW with electricity generation 139,000 GWh, of which 89 % was delivered by thermal plants and about 10% from Hydro power with total installed 2800 MW and electricity generated is about 12863 GWh and 1% from Wind energy with total installed 550 MW and electricity generated 1542 GWh. In the solar energy field, the first solar thermal power plant of 140 MW with a solar share of 20 MW using parabolic trough technology was started the initial work since the 1 st of July with estimated total energy generated of 852GWh/year. Recently, Egypt has adopted an ambitious plan to cover 20% of the generated electricity by renewable energy by 2020, including a 12% contribution from wind energy, translating more than 7200 MW grid-connected wind farms. Such plan gives a room enough to the private investment to play the major role in realizing this goal. The plan includes also a 100 MW Solar thermal energy CSP with parabolic trough technology in Kom Ombo city, and also two PV plants in Hurgada and Kom Ombo with a total installed capacity 20 MW each. Due to the high investment cost of solar energy technologies, still limited in spread all over the world on the other hand wind energy has an economic potential and becomes a commercial technology but the future potential for solar energy due to the limited land for wind energy. Current study will evaluate the Egyptian strategy for renewable energy up to 2020 and find how much the planned projects from the Egyptian government will fulfill its target, the economic study

    Full Text Available A number of strategies exist to reduce Clostridium difficile (C. difficile transmission. We conducted an economic evaluation of "bundling" these strategies together.We constructed an agent-based computer simulation of nosocomial C. difficile transmission and infection in a hospital setting. This model included the following components: interactions between patients and health care workers; room contamination via C. difficile shedding; C. difficile hand carriage and removal via hand hygiene; patient acquisition of C. difficile via contact with contaminated rooms or health care workers; and patient antimicrobial use. Six interventions were introduced alone and "bundled" together: (a aggressive C. difficile testing; (b empiric isolation and treatment of symptomatic patients; (c improved adherence to hand hygiene and (d contact precautions; (e improved use of soap and water for hand hygiene; and (f improved environmental cleaning. Our analysis compared these interventions using values representing 3 different scenarios: (1 base-case (BASE values that reflect typical hospital practice, (2 intervention (INT values that represent implementation of hospital-wide efforts to reduce C. diff transmission, and (3 optimal (OPT values representing the highest expected results from strong adherence to the interventions. Cost parameters for each intervention were obtained from published literature. We performed our analyses assuming low, normal, and high C. difficile importation prevalence and transmissibility of C. difficile.INT levels of the "bundled" intervention were cost-effective at a willingness-to-pay threshold of $100,000/quality-adjusted life-year in all importation prevalence and transmissibility scenarios. OPT levels of intervention were cost-effective for normal and high importation prevalence and transmissibility scenarios. When analyzed separately, hand hygiene compliance, environmental decontamination, and empiric isolation and treatment were the

    The Complex pegmatite - apelitic of Cabecinha corresponds to an isolated ridge that reaches 933 meters, located in the middle zone of transition between the Hesperian massif and the Cova da Beira being located in the NE central part of Portugal, more specifically in the Mountainous region of the province of Beira Alta, council of Sabugal. This complex lies embedded in porphyritic granites with terms of switching to a medium-grained granite rich in sodium feldspars in which they are muscovite granite intrusions. The lodes have pegmatites with NE-SW orientation, presenting phases of predominantly quartz crystallization with multiple parageneses. The inclusions observed are veins filonianian secondary. Some veins have structural discontinuity due to further their training tectonics. The apelitico material is basic in nature engaging in descontinuiddes of pegmatite material, showing no preferred orientation. The petrological characteristics of the area in question provide the appearance of motivating exotic landforms of scientific interest. These landforms, over time, have motivated the popular level the emergence of various myths, thus contributing to the enrichment of the local cultural heritage. This study proceeded to the geological and geomorphological mapping an area of about 6945,350 m2 with a maximum length of 182 m. The huge patent mineralogical, petrological and geomorphological level geodiversity, allied to the structural complexity and associated cultural heritage, allow geoconservation strategies and recovery, using new multimedia technologies including use of QR codes and 3D. All this geological framework and environment becomes an asset for the scientific, educational and economic development of the region. On the other hand, it has the vital Importance in the context of the strategy of forming a geological park, in the point of view of tourism, research and interpretation.

    Understanding human-wildlife conflict is an important first step in the conservation of highly endangered species that can have adverse effects on human communities, such as elephants. To gain insights into variables that shape attitudes toward elephant conservation in Asia, we surveyed 410 households and 46 plantation owners in seven villages around the Salakpra Wildlife Sanctuary in western Thailand, an area of high human-elephant conflict. We sought to evaluate how past experiences with elephants (positive or negative), as well as socio-economic variables (age, income level, gender, and employment type) affect attitudes toward elephant conservation and coexistence in this area. In addition, we quantified deterrence methods currently used and identify potential mitigation strategies supported by community members. In general, less supportive attitudes toward elephant conservation and coexistence were held by individuals older than 35 years of age, those who had previously had experienced negative interactions with elephants, those with lower incomes, and those working in the agricultural sector. Conversely, those who had received benefits from living near elephants (e.g., supplemental income or feelings of pride from hosting volunteers or participating in conservation work) had more supportive views of elephant coexistence. Plantation owners reported using a variety of deterrence methods with varying success, with firecrackers being the most commonly utilized method. Community members identified several potentially beneficial mitigation strategies including forest restorations and patrol teams, adding water sources to wild elephant habitat, and education of local school and community groups. Overall, our results highlight the value of community members receiving benefits from living near elephants and suggest that special incentives may be needed for demographic groups disproportionately affected by elephants (e.g. those at lower income levels, those working in

    Full Text Available Around 30% of the European building stock was built before 1950, when no regulations about energy efficiency were in force. Since only a small part of them has been renovated by now, the energy performance of this building stock is on average quite poor, resulting in a significant impact on the energy balance of European countries, as confirmed by data published by ISTAT (Italian National Statistical Institute. However, energy retrofit in historic edifices is a quite demanding issue as any intervention must take into account the need to preserve existing building materials and appearances while also allowing reversibility and low invasiveness. As an example, in these buildings it is not possible to apply an ETICS (External Thermal Insulation Composite System, since this would alter the historic and architectural value of the façade. On the other hand, internal insulation would have the drawback of reducing the net useful floor area, which also implies a loss of economic value. Moreover, internal insulation may induce overheating risks and mold formation. In this paper, all these issues are investigated with reference to an existing historic building located in southern Italy, showing that a retrofit strategy aimed at energy savings and cost-effectiveness is still possible if suitable materials and solutions are adopted.

    Full Text Available After the dissolution of the Habsburg Empire, leaders in successor states were eager to become economically independent from the former capital Vienna. They therefore quickly implemented a set of neomercantilistic measures, especially nationalization programs. Nevertheless, the 1920s saw a reestablishment of the common market in the former territories of the Habsburg Empire in terms of interregional trade and interlocking directorates, mainly because of the business strategy of international financial syndicates that were based on the traditional Viennese commercial relations with the successor states. The international credit of Jewish bankers like Louis Rothschild, Rudolf Sieghart, and Max Feilchenfeld and others mattered. After the “Big Bang” at Wall Street in 1929, the industrial holdings of the Viennese banks and the maturity problem (short-term borrowing, long-term lending in their relations to East European debtors and Western financiers caused the Creditanstalt-crisis of 1931 and put an end to Vienna’s position as a financial hub in East Central Europe. However, even during the crisis of the 1930s, the share of the successor states in the bilateral balances of trade indicates path dependency on a smaller scale.

    Full Text Available The article is based on long term field research and focuses on a community of family-related Vlax Roma from the Prešov, Sabinov and Košice regions who created a large community in Leicester, UK. The massive wave of labour migration to UK started in 2004, in the year of Slovakia’s accession to the European Union. The migration to Great Britain has been based on family networks and represents an example of chain migration based on the reciprocal help of family networks. Besides their own relatives other different non-related Roma intermediaries had an important influence on their arrival to Britain. The article focuses on the changing economic strategies of new migrants from the group in focus after their replacement to UK. In the years following Slovak accession to the EU, the prospective Romani migrants explored many illegal paths to arrive to Britain in their struggle for a better life. Approximately after a decade since their arrival, we can find this community as fully integrated into the local British working class, spending their time between my work and my house.

    As an application of probabilistic fracture mechanics (PFM) and a financial method, risk-benefit analyses were performed for the purpose of optimizing maintenance activities of steam generator (SG) tubes used in pressurized water reactors (PWRs). Parameters such as in-service inspection (ISI) detection accuracy, ISI interval, sampling inspection, replacement of SGs and stress corrosion cracking (SCC) allowance operation were selected for sensitivity analyses. In the analysis of the operation introducing maintenance criteria, the effect of quantitative accuracy of the inspection was also taken into account. Although the analyses were mainly conducted for SG tubes made of Inconel 600 mill anneal (MA) materials, the analyses were also performed for SCC-resistant materials with making assumptions on their crack initiation probabilities and crack propagation laws. To justify whether or not it is worth while implementing the selected maintenance strategies in terms of an economic point of view, net present value (NPV) was calculated as an index which is one of the most fundamental financial indices for decision-making based on the discounted cash flow (DCF) method.

    Full Text Available Expatriation is a widely studied area of research in work and organizational psychology. After expatriates accomplish their missions in host countries, they return to their countries and this process is called repatriation. Adjustment constitutes a crucial part in repatriation research. In the present literature review, research about repatriation adjustment was reviewed with the aim of defining the whole picture in this phenomenon. Present research was classified on the basis of a theoretical model of repatriation adjustment. Basic frame consisted of antecedents, adjustment, outcomes as main variables and personal characteristics/coping strategies and organizational strategies as moderating variables.

  6. How to reconcile environmental and economic performance to improve corporate sustainability: corporate environmental strategies in the European paper industry.

    Wagner, Marcus

    2005-07-01

    This paper discusses the relationship between environmental and economic performance and the influence of corporate strategies with regard to sustainability and the environment. After formulating a theoretical model, results are reported from an empirical analysis of the European paper manufacturing industry. New data are used to test hypotheses derived from the theoretical model, using environmental performance indices representing different corporate environmental strategy orientations. In particular, an emissions-based index largely reflecting end-of-pipe strategies and an inputs-based index reflecting integrated pollution prevention are distinguished. For the emissions-based index, a predominantly negative relationship between environmental and economic performance is found, whereas for the inputs-based index no significant link is found. This is consistent with the theoretical model, which predicts the possibility of different relationships. The results also show that for firms with pollution prevention-oriented corporate environmental strategies, the relationship between environmental and economic performance is more positive, thus making improvements in corporate sustainability more likely. Based on this last insight, managerial implications of this are discussed with regard to strategy choices, investment decisions and operations management.

    Pre-exposure prophylaxis (PrEP) with antiretrovirals is an efficacious and effective intervention to decrease the risk of HIV (human immunodeficiency virus) acquisition. Yet drug and delivery costs prohibit access in many jurisdictions. In the absence of guidelines for the synthesis of economic evaluations, we developed a protocol for a systematic review of economic evaluation studies for PrEP by drawing on best practices in systematic reviews and the conduct and reporting of economic evaluations. We aim to estimate the incremental cost per health outcome of PrEP compared with placebo, no PrEP, or other HIV prevention strategies; assess the methodological variability in, and quality of, economic evaluations of PrEP; estimate the incremental cost per health outcome of different PrEP implementation strategies; and quantify the potential sources of heterogeneity in outcomes. We will systematically search electronic databases (MEDLINE, Embase) and the gray literature. We will include economic evaluation studies that assess both costs and health outcomes of PrEP in HIV-uninfected individuals, without restricting language or year of publication. Two reviewers will independently screen studies using predefined inclusion criteria, extract data, and assess methodological quality using the Philips checklist, Second Panel on the Cost-effectiveness of Health and Medicines, and the International Society for Pharmacoeconomics and Outcomes Research recommendations. Outcomes of interest include incremental costs and outcomes in natural units or utilities, cost-effectiveness ratios, and net monetary benefit. We will perform descriptive and quantitative syntheses using sensitivity analyses of outcomes by population subgroups, HIV epidemic settings, study designs, baseline intervention contexts, key parameter inputs and assumptions, type of outcomes, economic perspectives, and willingness to pay values. Findings will guide future economic evaluation of PrEP strategies in terms of

    2007-01-01

    Full Text Available Are sources of economic rent, as defined by the prevalent business strategy paradigm, sufficient to attain and maintain superior returns? The perspective developed within the conceptual framework of the Institutional Theory may offer managers a contribution towards understanding the strategy process and its potentialities,particularly by stressing the leading role played by legitimacy, the influence of many institutional spheres, the isomorphic pressures, ceremonial behavior and decoupling, among other elements, that mainstream business strategy fails to address directly, but which may have a significant effect on firm performance. We advance thatthese elements must be accounted for in the pursuit and acquisition of economic rents, even if the ability to articulate them purposefully is constrained by rationality, agency conditions and the manager's social embeddedness.

    Full Text Available Diversification strategies adopted by oil-depended economies' played an important role in the economic development in these countries, which rely heavily on oil exports. UAE as an oil-dependency economy has the type of strategy to diversify the sources of its national income and reduce its dependence on oil to counter the instability in global oil prices. This paper seek to investigate whether the diversification strategies adopted by (UAE is adequate to manage its economic development. The methodology employed in this study is to examine the contribution of diversified sectors based on the country's GDP especially during and after the global financial crisis (2008-2012 using statistical analysis procedure. The results confirm that investment in different sectors rather than oil would have substantially improved the performance UAE economy.

    This paper studies the Europeanization of media coverage of the European Union's (EU) socio-economic strategy, which is a crucial building block for developing a European Public Sphere. As the EU level increasingly influences public policy in member states, there should correspondingly be a more...... intense and visible media debate with attention for EU-level and cross-national policies and developments. On the basis of a content analysis (2000–2010) in Denmark, France, Poland and the UK, we find that media attention for the EU's growth and jobs strategy is limited, that it does not increase over...... in terms of benchmarking and reporting on criticism and advice to member states. This criticism is more often diffuse than aimed at specific member states.

    Health care providers must effectively function in highly skilled teams in a collaborative manner, but there are few interprofessional training strategies in place. Interprofessional education (IPE) using simulation technology has gained popularity to address this need because of its inherent ability to impact learners' cognitive frames and promote peer-to-peer dialog. Provider attitudes toward teamwork have been directly linked to the quality of patient care. Investigators implemented a simulation-enhanced IPE intervention to improve staff attitudes toward teamwork and interprofessional communication in the emergency department setting. The 3-hour course consisted of a didactic session highlighting teamwork and communication strategies, 2 simulation scenarios on septic shock and cardiac arrest, and structured debriefing directed at impacting participant attitudes to teamwork and communication. This was a survey-based observational study. We used the TeamSTEPPS Teamwork Attitudes Questionnaire immediately before and after the session as a measurement of attitude change as well as the Hospital Survey on Patient Safety Culture before the session and 1 year after the intervention for program impact at the behavior level. Seventy-two emergency department nurses and resident physicians participated in the course from July to September 2012. Of the 5 constructs in TeamSTEPPS Teamwork Attitudes Questionnaire, 4 had a significant improvement in scores-6.4%, 2.8%, 4.0%, and 4.0% for team structure, leadership, situation monitoring, and mutual support, respectively (P teamwork and communication showed a significant improvement-20.6%, 20.5%, and 23.9%, for frequency of event reporting, teamwork within hospital units, and hospital handoffs and transitions, respectively (P = 0.028, P = 0.035, and P = 0.024, respectively). A simulation-enhanced IPE curriculum was successful in improving participant attitudes toward teamwork and components of patient safety culture related to

    Air pollution continues to be a problem in the urban environment. A range of different pollutant mitigation strategies that promote dispersion and deposition exist, but there is little evidence with respect to their comparative performance from both an environmental and economic perspective. This paper focuses on examining different NO 2 mitigation strategies such as trees, buildings facades coated with photocatalytic paint and solid barriers in Oxford Street in London. The case study findings will support ranking the environmental and economic impacts of these different strategies to improve personal exposure conditions on the footpath and on the road in a real urban street canyon. CFD simulations of airflow and NO 2 dispersion in Oxford Street in London were undertaken using the OpenFOAM software platform with the k-ε model, taking into account local prevailing wind conditions. Trees are shown to be the most cost-effective strategy, with a small reduction in NO 2 concentrations of up to 0.7% on the road. However, solid barriers with and without the application of photocatalytic paint and an innovative material (20 times more expensive than trees) can improve air quality on the footpaths more substantially, up to 7.4%, yet this has a significant detrimental impact on NO 2 concentrations (≤23.8%) on the road. Photocatalytic paint on building surfaces presented a minimal environmental reductions (1.2%) and economic (>100 times more expensive than trees) mitigation strategy. The findings recognised the differences between footpath and road concentrations occurred and that a focused examination of three pollution hotspots can provide more cost effective pollution mitigation. This study considers how a number of pollutant mitigation measures can be applied in a single street canyon and demonstrates the strengths and weaknesses of these strategies from economic and environmental perspectives. Further research is required to extrapolate the findings presented here to

    Options for treatment and discharge of wastewater in regional Western Australia (WA) are examined from the perspective of overall sustainability and social net benefit. Current practice in the state has typically involved a basic standard of treatment deemed to be protective of human health, followed by discharge to surface water bodies. Community and regulatory pressure to move to higher standards of treatment is based on the presumption that a higher standard of treatment is more protective of the environment and society, and thus is more sustainable. This analysis tests that hypothesis for Western Australian conditions. The merits of various wastewater treatment and discharge strategies are examined by quantifying financial costs (capital and operations), and by monetising the wider environmental and social costs and benefits of each option over an expanded planning horizon (30 years). Six technical treatment-disposal options were assessed at a test site, all of which met the fundamental criterion of protecting human health. From a financial perspective, the current business-as-usual option is preferred - it is the least cost solution. However, valuing externalities such as water, greenhouse gases, ecological impacts and community amenity, the status quo is revealed as sub-optimal. Advanced secondary treatment with stream disposal improves water quality and provides overall net benefit to society. All of the other options were net present value (NPV) negative. Sensitivity analysis shows that the favoured option outperforms all of the others under a wide range of financial and externality values and assumptions. Expanding the findings across the state reveals that moving from the identified socially optimal level of treatment to higher (tertiary) levels of treatment would result in a net loss to society equivalent to several hundred million dollars. In other words, everyone benefits from improving treatment to the optimum point. But society, the environment, and

    The IAEA, in co-operation with the European Commission, the Nuclear Energy Agency of the OECD and the Uranium Institute, organized an international symposium to discuss the 'new realities' in the nuclear fuel cycle with special emphasis on plutonium management. The symposium covered all aspects of the fuel cycle in six sessions: Global Energy Outlook; Present Status and Immediate Prospects of Plutonium Management; Future Fuel Cycle and Reactor Strategies; Safety, Health and Environmental Implications of the Different Fuel Cycles; Non-Proliferation and Safeguards Aspects; and International Co-operation. The Symposium took place in Vienna, 3-6 June 1997. About 300 participants from 41 countries and 4 international organizations attended. The Symposium gave a comprehensive overview on the present situation of the fuel cycle and the expected developments up to 2050. During this period nuclear energy will continue to be dominated by Thermal Reactors; Fast Reactors will be introduced slowly after 2030. In general, an evolutionary and not a revolutionary process is expected. (orig.) [de

    At this year's annual meeting of the Nuclear Forum Switzerland (Nuklearforums Schweiz) once again the 2050 Energy Strategy of the Swiss Federal Council (Schweizer Bundesrat) was the main topic. President Corina Eichenberger warned against political arbitrariness and reckless endangerment of the Swiss electricity supply. Instead she called for a more logical, a more rational and more a pragmatic discussion. Accordingly, Eichenberger dismissed clearly politically motivated operation restrictions for Swiss nuclear power plants. The guest speakers Prof. Peter Egger of the Economic Institute of the ETH Zurich and Christoph Mader, President of scienceindustries, discussed consequences of the 2050 energy strategy for economy and industry. About 130 guests from the nuclear industry, politicians and industry took part in the Annual Meeting of the Nuclear Forum to the Hotel Bellevue in Bern Switzerland. Again, the event 'The 2050 energy strategy in the context of economic reality' was of main interest due to the recent energy policy discussions. Corinna Eichenberger, President of the association, stated, that the audience received an deep view into the economic consequences of the 2050 energy strategy from the perspective of science and industry.

    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

    Highlights: • We compare GHG mitigation policy including or excluding CCS on socio-economic impacts for the Netherlands. • We simulate these policy options in a global multiregional Input-Output Model with detailed bottom-up technology data. • Economy-wide differentials between these mitigation policies are small for Employment, GDP and Imports. • Notable impacts are found for the energy sector and some upstream sectors (natural gas, construction). • This pattern shows to base a choice on macroeconomic impacts is hard and it will affect strong and vested interests. - Abstract: Carbon Capture and Storage (CCS) could be an interesting option to mitigate greenhouse gas emissions in the Netherlands. This study compares a mitigation strategy for the Dutch power sector that includes CCS to one without on several socio-economic indicators. In particular, we calculate incremental gross value added (GVA), employment and import dependency impacts of two such low-carbon power production portfolios for the Netherlands. We combine technology specific techno-economic bottom-up data with a macro-economic multi-regional Input-Output-Table containing high sectoral detail. For the total economy, we find the differences between these scenarios to be small. Still, gross value added, and employment are lower under the CCS-inclusive strategy, while import dependency is higher. For the power sector, the differences between the scenarios are, however, considerable. Furthermore, our analysis shows that also for other sectors the differences between the scenarios could be large. For instance, a CCS-exclusive strategy leads to considerably higher GVA and employment in domestic construction services, while the CCS-inclusive strategy comes with considerably higher GVA and employment for natural gas mining and related upstream sectors.

    Patients with persistent or recurrent neutropenic fevers at risk of invasive fungal disease (IFD) are treated empirically with antifungal therapy (AFT). Early treatment using a diagnostic-driven (DD) strategy may reduce clinical and economic burdens. We compared costs and outcomes of both strategies from a UK perspective. An empirical strategy with conventional amphotericin B deoxycholate (C-AmB), liposomal amphotericin B (L-AmB), or caspofungin was compared with a DD strategy (initiated based on positive ELISA results for galactomannan antigen) and/or positive results for Aspergillus species on polymerase chain reaction assay) using C-AmB, voriconazole, or L-AmB in a decision-analytic model. Rates of IFD incidence, overall mortality, and IFD-related mortality in adults expected to be neutropenic for ≥10 days were obtained. The empirical strategy was assumed to identify 30% of IFD and targeted AFT to improve survival by a hazard ratio of 0.589. AFT-specific adverse events were obtained from a summary of product characteristics. Resource use was obtained, and costs were estimated by using standard UK costing sources. All costs are presented in 2012 British pounds sterling. Total costs were 32% lower for the DD strategy (£1561.29) versus the empirical strategy (£2301.93) due to a reduced incidence of adverse events and decreased use of AFT. Administration of AFT was reduced by 41% (DD strategy, 74 of 1000; empirical strategy, 125 of 1000), with similar survival rates. This study suggests that a DD strategy is likely to be cost-saving versus empirical treatment for immunocompromised patients with persistent or recurrent neutropenic fevers.

  4. Adult vaccination strategies for the control of pertussis in the United States: an economic evaluation including the dynamic population effects.

    Directory of Open Access Journals (Sweden)

    Laurent Coudeville

    Full Text Available BACKGROUND: Prior economic evaluations of adult and adolescent vaccination strategies against pertussis have reached disparate conclusions. Using static approaches only, previous studies failed to analytically include the indirect benefits derived from herd immunity as well as the impact of vaccination on the evolution of disease incidence over time. METHODS: We assessed the impact of different pertussis vaccination strategies using a dynamic compartmental model able to consider pertussis transmission. We then combined the results with economic data to estimate the relative cost-effectiveness of pertussis immunization strategies for adolescents and adults in the US. The analysis compares combinations of programs targeting adolescents, parents of newborns (i.e. cocoon strategy, or adults of various ages. RESULTS: In the absence of adolescent or adult vaccination, pertussis incidence among adults is predicted to more than double in 20 years. Implementing an adult program in addition to childhood and adolescent vaccination either based on 1 a cocoon strategy and a single booster dose or 2 a decennial routine vaccination would maintain a low level of pertussis incidence in the long run for all age groups (respectively 30 and 20 cases per 100,000 person years. These strategies would also result in significant reductions of pertussis costs (between -77% and -80% including additional vaccination costs. The cocoon strategy complemented by a single booster dose is the most cost-effective one, whereas the decennial adult vaccination is slightly more effective in the long run. CONCLUSIONS: By providing a high level of disease control, the implementation of an adult vaccination program against pertussis appears to be highly cost-effective and often cost-saving.

Drawing on a critique of the glocalisation thesis we show that the design of these strategies can plausibly be explained by the specific characteristics of urban capitalism found in the different cities. Whereas the international strategy of Manchester must be seen as a response to problems of postindustrial restrictions, the importance of the logistic sector in Dutch capitalism strong...

    Full Text Available The main objective of this study is to investigate the causal relationship between tourism development and economic growth in Gulf Cooperation Council (GCC countries in a multivariate model, using panel data for the period 1995–2012. The study adopts a panel Granger causality analysis approach to assess the contribution of tourism to economic growth in GCC countries as a whole, and in each individual country. In the case of GCC countries as a whole, the results show a one-way Granger causality, from economic growth to tourism growth. Furthermore, Kuwait, Saudi Arabia, Qatar, and the United Arab Emirates follow the path of economy-driven tourism growth, as hypothesized. The reverse hypothesis (i.e., tourism-led growth hypothesis holds true for Bahrain, while there is no causal relationship between tourism and economic growth in the case of Oman.

    Full Text Available The aim of this study was to analyze feeding practices in Costa Rica’s dairy farms and their influence on greenhouse gas emissions (GHG. Methane (CH4, nitrous oxide (N2O, and income over feed cost (IOFC were evaluated. This study was carried out at 104 dairy farms, which were distributed within a range of altitude from 1000 to 2400 meters above sea level. Using cluster analysis based on type of feed, grazing period, areas of forage and pastures; four feeding strategies were identified, which included different proportions of feed categories in daily rations. Emissions expressed as carbon dioxide equivalent per kilo of fat and protein corrected milk (CO2eq/FPCM were higher for forage feeding strategies and lower for farms found in higher altitudes. Concentrate feed accounted for the higher cost in all feeding strategies, and represented more than 50% in the intensive concentrate based production system, whereas the costs of fertilizers were higher in pasture based feeding strategies. Income from milk sales was higher for the concentrate based feeding strategy. However, IOFC was the same for all feeding strategies in spite of the large differences in daily milk production. Feeding strategies influenced GHG emissions and feeding costs. Feeding strategies associated with lower GHG emissions within the farm were more dependent from external inputs.

    Background and aims The Burden of Communicable Diseases in Europe (BCoDE) study aimed to calculate disability-adjusted life years (DALYs) for 31 selected diseases in the European Union (EU) and European Economic Area (EEA). Methods: DALYs were estimated using an incidence-based and pathogen-based approach. Incidence was estimated through assessment of data availability and quality, and a correction was applied for under-estimation. Calculation of DALYs was performed with the BCoDE software toolkit without applying time discounting and age-weighting. Results: We estimated that one in 14 inhabitants experienced an infectious disease episode for a total burden of 1.38 million DALYs (95% uncertainty interval (UI): 1.25–1.5) between 2009 and 2013; 76% of which was related to the acute phase of the infection and its short-term complications. Influenza had the highest burden (30% of the total burden), followed by tuberculosis, human immunodeficiency virus (HIV) infection/AIDS and invasive pneumococcal disease (IPD). Men had the highest burden measured in DALYs (60% of the total), adults 65 years of age and over had 24% and children less than 5 years of age had 11%. Age group-specific burden showed that infants (less than 1 year of age) and elderly people (80 years of age and over) experienced the highest burden. Conclusions: These results provide baseline estimates for evaluating infectious disease prevention and control strategies. The study promotes an evidence-based approach to describing population health and assessing surveillance data availability and quality, and provides information for the planning and prioritisation of limited resources in infectious disease prevention and control.

    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.

    1993-01-01

    Optimal control theory is applied to develop an efficient strategy to control stock pollutants such as greenhouse gases and hazardous waste. The optimal strategy suggests that, at any time, the marginal costs of abatement should be equated with the present value of the marginal damage of timely unabated emission. The optimal strategy calls for increasingly tight abatement over time as the pollutant stock accumulates. The optimal policy applied to greenhouse gases suggest moderate abatement efforts, at present, with the potential for much greater future efforts. 15 refs., 2 tabs

    The aim of the present paper is to evaluate the economic efficiency of the public control and prevention strategies to tackle the 2010 West Nile Virus (WNV) outbreak in the Region of Central Macedonia, Greece. Efficiency is examined on the basis of the public prevention costs incurred and their potential in justifying the costs arising from health and nuisance impacts in the succeeding years. Economic appraisal of public health management interventions. Prevention and control cost categories including control programmes, contingency planning and blood safety testing, are analyzed based on market prices. A separate cost of illness approach is conducted for the estimation of medical costs and productivity losses from 2010 to 2013 and for the calculation of averted health impacts. The averted mosquito nuisance costs to households are estimated on the basis of a contingent valuation study. Based on these findings, a limited cost-benefit analysis is employed in order to evaluate the economic efficiency of these strategies in 2010-2013. Results indicate that cost of illness and prevention costs fell significantly in the years following the 2010 outbreak, also as a result of the epidemic coming under control. According to the contingent valuation survey, the annual average willingness to pay to eliminate the mosquito problem in the study area ranged between 22 and 27 € per household. Cost-benefit analysis indicates that the aggregate benefit of implementing the previous 3-year strategy creates a net socio-economic benefit in 2013. However the spread of the WNV epidemic and the overall socio-economic consequences, had the various costs not been employed, remain unpredictable and extremely difficult to calculate. The application of a post epidemic strategy appears to be of utmost importance for public health safety. An updated well designed survey is needed for a more precise definition of the optimum prevention policies and levels and for the establishment of the various

    In South Korea, there have been debates on the welfare policies of the Kim Dae-jung government after the economic crisis beginning in late 1997, but it is unquestionable that health and health care policies have followed the trend of neoliberal economic and social polices. Public health measures and overall performance of the public sector have weakened, and the private health sector has further strengthened its dominance. These changes have adversely affected the population's health status and access to health care. However, the anti-neoliberal coalition is preventing the government's drive from achieving a full success.

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

    This review determines the characteristics and health-related and economic outcomes of employer-sponsored wellness programs and identifies possible reasons for their success. PubMed, ABI/Inform, and Business Source Premier databases, and Corporate Wellness Magazine were searched. English-language articles published from 2005 to 2011 that reported characteristics of employer-sponsored wellness programs and their impact on health-related and economic outcomes among US employees were accepted. Data were abstracted, synthesized, and interpreted. Twenty references were accepted. Wellness interventions were classified into health assessments, lifestyle management, and behavioral health. Improved economic outcomes were reported (health care costs, return on investment, absenteeism, productivity, workers' compensation, utilization) as well as decreased health risks. Programs associated with favorable outcomes had several characteristics in common. First, the corporate culture encouraged wellness to improve employees' lives, not only to reduce costs. Second, employees and leadership were strongly motivated to support the wellness programs and to improve their health in general. Third, employees were motivated by a participation-friendly corporate policy and physical environment. Fourth, successful programs adapted to the changing needs of the employees. Fifth, community health organizations provided support, education, and treatment. Sixth, successful wellness programs utilized technology to facilitate health risk assessments and wellness education. Improved health-related and economic outcomes were associated with employer-sponsored wellness programs. Companies with successful programs tended to include wellness as part of their corporate culture and supported employee participation in several key ways.

    The Baros mangrove forest in Bantul Regency is now beginning to develop. Many government and private sectors programs are rolled out to support its development. The development of the Baros mangrove forest must be in accordance with the rules of conservation so that it will not damage the mangrove ecosystem. Mangrove forest has high economical and ecological value but is very vulnerable if lack of wisdom in maintaining, preserving and managing them. The involvement of government and other stakeholders are essential in determining management policies. Unawareness of society and the government to the importance of mangrove ecosystem can cause development of it becomes uncontrolled, consequently can destroy it. Mangrove forests are an important natural resource in coastal environments, and have three main functions: physical, biological, and economic functions. To quantify the functions of mangrove forests as the basis to determine the policy is required a research instrument called economic valuation. The approach of this study is the literature review from various studies before to perceive the influence of economic valuation in determining the management strategy of Baros mangrove forest in Bantul Regency, Yogyakarta, Indonesia.

    2015-04-01

    Full Text Available Organic Rankine cycles (ORCs are an established technology to convert waste heat to electricity. Although several commercial implementations exist, there is still considerable potential for thermo-economic optimization. As such, a novel framework for designing optimized ORC systems is proposed based on a multi-objective optimization scheme in combination with financial appraisal in a post-processing step. The suggested methodology provides the flexibility to quickly assess several economic scenarios and this without the need of knowing the complex design procedure. This novel way of optimizing and interpreting results is applied to a waste heat recovery case. Both the transcritical ORC and subcritical ORC are investigated and compared using the suggested optimization strategy.

    2015-04-01

    Guidelines recommendations regarding anticoagulant therapy after percutaneous coronary intervention (PCI) among patients with atrial fibrillation (AF) rely on retrospective, nonrandomized observational data. Currently, patients are treated with triple-therapy (dual antiplatelet therapy [DAPT] + oral anticoagulation therapy), but neither the duration of DAPT nor the level of anticoagulation has been studied in a randomized fashion. Recent studies also suggest dual pathway therapy with clopidogrel plus oral anticoagulation therapy may be superior, and other studies suggest that novel oral anticoagulants such as rivaroxaban may further improve patient outcomes. PIONEER AF-PCI (ClinicalTrials.gov NCT01830543) is an exploratory, open-label, randomized, multicenter clinical study assessing the safety of 2 rivaroxaban treatment strategies and 1 vitamin K antagonist (VKA) treatment strategy in subjects who have paroxysmal, persistent, or permanent nonvalvular AF and have undergone PCI with stent placement. Approximately 2,100 subjects will be randomized in a 1:1:1 ratio to receive either rivaroxaban 15 mg once daily plus clopidogrel 75 mg daily for 12 months (a WOEST trial-like strategy), or rivaroxaban 2.5 mg twice daily (with stratification to a prespecified duration of DAPT 1, 6, or 12 months, an ATLAS trial-like strategy), or dose-adjusted VKA once daily (with stratification to a prespecified duration of DAPT 1, 6, or 12 months, traditional triple therapy). All patients will be followed up for 12 months for the primary composite end point of Thrombolysis in Myocardial Infarction major bleeding, bleeding requiring medical attention, and minor bleeding (collectively, clinically significant bleeding). The PIONEER AF-PCI study is the first randomized comparison of VKA vs novel oral anticoagulant therapy in patients with NVAF receiving antiplatelet therapy after PCI to assess the relative risks of bleeding complications.

    This paper, which also appears as an Appendix to the Final Working Group 4 Report, forms part of the overall economic evaluation of reprocessing. The indicative position and illustrative ''phase diagram'' for the Commission of the European Communities (CEC) is presented. The European Community has to import 80% or more of the uranium needed to fuel its nuclear power capacity. Nuclear fuel reprocessing together with recycle of the recovered uranium and plutonium has the potential to reduce the uranium needs of the Community some 20 to 25% during the near term period 1990-2000 and in the longer term (after 2000) with the gradual introduction of fast breeder reactors to decrease sharply the need to import uranium. This illustrates the high economic value assigned to fuel reprocessing within the European Community

    Krieger, L M; Shaw, W W

    1999-02-01

    The laws of microeconomics explain how prices affect consumer purchasing decisions and thus overall revenues and profits. These principles can easily be applied to the behavior aesthetic plastic surgery patients. The UCLA Division of Plastic Surgery resident aesthetics clinic recently offered a radical price change for its services. The effects of this change on demand for services and revenue were tracked. Economic analysis was applied to see if this price change resulted in the maximization of total revenues, or if additional price changes could further optimize them. Economic analysis of pricing involves several steps. The first step is to assess demand. The number of procedures performed by a given practice at different price levels can be plotted to create a demand curve. From this curve, price sensitivities of consumers can be calculated (price elasticity of demand). This information can then be used to determine the pricing level that creates demand for the exact number of procedures that yield optimal revenues. In economic parlance, revenues are maximized by pricing services such that elasticity is equal to 1 (the point of unit elasticity). At the UCLA resident clinic, average total fees per procedure were reduced by 40 percent. This resulted in a 250-percent increase in procedures performed for representative 4-month periods before and after the price change. Net revenues increased by 52 percent. Economic analysis showed that the price elasticity of demand before the price change was 6.2. After the price change it was 1. We conclude that the magnitude of the price change resulted in a fee schedule that yielded the highest possible revenues from the resident clinic. These results show that changes in price do affect total revenue and that the nature of these effects can be understood, predicted, and maximized using the tools of microeconomics.

    Estuaries are transitional areas between the land and sea and home to a large and growing proportion of the world's population. They are highly productive ecosystems which create jobs, and boosts local economic growth with a higher percentage of collective and private enterprises and a larger share of production. They serve many important socio-economic functions and therefore receive untreated urban wastes and riverine inputs and concentrate various pollutants coming from inland domestic, agricultural and industrial activities. Therefore such kinds of complex systems are highly vulnerable because they are usually the sink for the hinterlands. Due to serious environmental problems felt more intensively day by day, central and local governments must adopt an integrated policy and decision making process to promote a balance of uses. As surrounded by many historical attractions, heritage sites, buzzing cultural scenes and other natural resources, the Haliç (the Golden Horn estuary) offers great opportunities and has a vitality fed by widespread economic and cultural factors. The typical landscape of the estuary, its bridges, geomorphic features, oceanographic and hydrodynamic features of its waters, sea bottom characteristics, environmental pollution, make this estuary a critical marine environment which impacts to economy, environment and community. However, rapid urban growth and uncontrolled industrial development (1950-1985) led to a severe increase in pollution levels of its water and cohesive sediments. The siltation due to liquid and solid waste dumped by two streams caused anaerobic decomposition problems. In addition, the ecological processes occurring in the Haliç are rather complex as they are interacted with the socio-economic system. This study focuses on the essential elements of integrated coastal zone management for the Haliç, and its probable impacts to economy, environment and community. All objectives and probable impacts need to be integrated

    International Nuclear Information System (INIS)

    Welsh, J.

    1995-12-01

    Nuclear power plants have available a number of alternative courses of action that can contribute to the reduction of personnel exposure to radiation. Possible actions at boiling water reactor (BWR) plants include accelerating the replacement of high-cobalt control rod blades (CRB) or the blades' high-cobalt pins and rollers with low or non-cobalt substitutes. To help utilities understand the exposure reduction and the economic costs and benefits associated with management alternatives, such as accelerated replacement of blades, pins and rollers, EPRI has initiated a project called Cost/Benefit Software for Analyses of Radiation Control Measures (RP1935-32). Through this project EPRI will incorporate engineering-economic techniques into a series of analytical tools that will provide useful insights about alternative exposure reduction options. Prototype software has been developed in an Excel worksheet to analyze issues associated with BWR control rod blade management options. The CRB replacement problem framework and analysis methodology incorporated into the software tool will help plant managers consider explicitly key engineering and economic issues that are relevant to exposure reduction decisions. This tool generates results that can help plant managers make decisions that are fiscally wise by showing all the cost and benefit implications associated with a management action under consideration. This report describes the general analytical approach for evaluating exposure reduction alternatives. The methodology used to analyze blade and pin and roller replacement alternatives, and the results of a case study application of the methodology and the software prototype at Commonwealth Edison

    Identification of alterations in ALK gene and development of ALK-directed therapies have increased the need for accurate and efficient detection methodologies. To date, research has focused on the concordance between the two most commonly used technologies, fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC). However, inter-test concordance reflects only one, albeit important, aspect of the diagnostic process; laboratories, hospitals, and payors must understand the cost and workflow of ALK rearrangement detection strategies. Through literature review combined with interviews of pathologists and laboratory directors in the U.S. and Europe, a cost-impact model was developed that compared four alternative testing strategies-IHC only, FISH only, IHC pre-screen followed by FISH confirmation, and parallel testing by both IHC and FISH. Interviews were focused on costs of reagents, consumables, equipment, and personnel. The resulting model showed that testing by IHC alone cost less ($90.07 in the U.S., $68.69 in Europe) than either independent or parallel testing by both FISH and IHC ($441.85 in the U.S. and $279.46 in Europe). The strategies differed in cost of execution, turnaround time, reimbursement, and number of positive results detected, suggesting that laboratories must weigh the costs and the clinical benefit of available ALK testing strategies.

    Employing electric vehicles as short-term energy storage could improve power system stability and at the same time create a new income source for vehicle owners. In this paper, the economic viability of this concept referred to as Vehicle-to-Grid is investigated. For this purpose, a price-responsive charging and dispatching strategy built upon temporally resolved electricity market data is presented. This concept allows vehicle owners to maximize returns by restricting market participation to profitable time periods. As a case study, this strategy is then applied using the example of Singapore. It is shown that an annual loss of S 1000 resulting from a non-price-responsive strategy as employed in previous works can be turned into a S 130 profit by applying the price-responsive approach. In addition to this scenario, realistic mobility patterns which restrict the temporal availability of vehicles are considered. In this case, profits in the range of S 21-S 121 are achievable. Returns in this order of magnitude are not expected to make Vehicle-to-Grid a viable business case, sensitivity analyses, however, show that improved technical parameters could increase profitability. It is further assumed that employing the price-responsive strategy to other national markets may yield significantly greater returns.

    Full Text Available Abstract Background A standard of prehospital care for patients presenting with ST-segment elevation myocardial infarction (STEMI includes prehospital 12-lead and advance Emergency Department notification or prehospital bypass to percutaneous coronary intervention centres. Implementation of either care strategies is variable across communities and neither may exist in some communities. The main objective is to compare prehospital care strategies for time to treatment and survival outcomes as well as cost effectiveness. Methods/Design PREDICT is a multicentre, prospective population-based cohort study of all chest pain patients 18 years or older presenting within 30 mins to 6 hours of symptom onset and treated with nitroglycerin, transported by paramedics in a number of different urban and rural regions in Ontario. The primary objective of this study is to compare the proportion of study subjects who receive reperfusion within the target door-to-reperfusion times in subjects obtained after four prehospital strategies: 12-lead ECG and advance emergency department (ED notification or 3-lead ECG monitoring and alert to dispatch prior to hospital arrival; either with or without the opportunity to bypass to a PCI centre. Discussion We anticipate four challenges to successful study implementation and have developed strategies for each: 1 diversity in the interpretation of the ethical and privacy issues across 47 research ethics boards/commiittees covering 71 hospitals, 2 remote oversight of data guardian abstraction, 3 timeliness of implementation, and 4 potential interference in the study by concurrent technological advances. Research ethics approvals from academic centres were obtained initially and submitted to non academic centre applications. Data guardians were trained by a single investigator and data entry is informed by a detailed data dictionary including variable definitions and abstraction instrucations and subjected to error and logic

With a use of new evidences from the Russian state archive of social and political history the author argues that the Conference was not just a reaction to the Marshall Plan and Shuman Plan in Western Europe. It was the first attempt to open the iron curtain and change the logic of international relations towards peaceful coexistence. The Conference turned into quite unusual for the period of late Stalin's rule nursery for fresh ideas used in full by USSR later in 1950-1970s.

  5. The Economic Merits of Flexible Carbon Capture and Sequestration as a Compliance Strategy with the Clean Power Plan.

    Carbon capture and sequestration (CCS) may be a key technology for achieving large CO 2 emission reductions. Relative to "normal" CCS, "flexible" CCS retrofits include solvent storage that allows the generator to temporarily reduce the CCS parasitic load and increase the generator's net efficiency, capacity, and ramp rate. Due to this flexibility, flexible CCS generators provide system benefits that normal CCS generators do not, which could make flexible CCS an economic CO 2 emission reduction strategy. Here, we estimate the system-level cost effectiveness of reducing CO 2 emissions with flexible CCS compared to redispatching (i.e., substituting gas- for coal-fired electricity generation), wind, and normal CCS under the Clean Power Plan (CPP) and a hypothetical more stringent CO 2 emission reduction target ("stronger CPP"). Using a unit commitment and economic dispatch model, we find flexible CCS achieves more cost-effective emission reductions than normal CCS under both reduction targets, indicating that policies that promote CCS should encourage flexible CCS. However, flexible CCS is less cost effective than wind under both reduction targets and less and more cost effective than redispatching under the CPP and stronger CPP, respectively. Thus, CCS will likely be a minor CPP compliance strategy but may play a larger role under a stronger emission reduction target.

    Exposure to patients with varicella or herpes zoster causes considerable disruption to a health care facility's operations and has a significant health and economic impact. However, practices related to screening for immunity and immunization of health care personnel (HCP) for varicella vary widely. A decision tree model was built to evaluate the cost-effectiveness of 8 different strategies of screening and vaccinating HCP for varicella. The outcomes are presented as probability of acquiring varicella, economic impact of varicella per employee per year, and cost to prevent additional cases of varicella. Monte Carlo simulations and 1-way sensitivity analyses were performed to address the uncertainties inherent to the model. Alternative epidemiologic and technologic scenarios were also analyzed. Performing a clinical screening followed by serologic testing of HCP with negative history diminished the cost impact of varicella by >99% compared with not having a program. Vaccinating HCP with negative screen cost approximately $50,000 per case of varicella prevented at the current level of U.S. population immunity, but was projected to be cost-saving at 92% or lower immunity prevalence. Improving vaccine acceptance rates and using highly sensitive assays also optimize cost-effectiveness. Strategies relying on screening and vaccinating HCP for varicella on employment were shown to be cost-effective for health care facilities and are consistent with current national guidelines for varicella prevention.

  7. Hydro-economic performances of streamflow withdrawal strategies: the case of small run-of-river power plants

    2014-05-01

    River flows withdrawals to supply small run-of-river hydropower plants have been increasing significantly in recent years - particularly in the Alpine area - as a consequence of public incentives aimed at enhancing energy production from renewable sources. This growth further raised the anthropic pressure in areas traditionally characterized by an intense exploitation of water resources, thereby triggering social conflicts among local communities, hydropower investors and public authorities. This brought to the attention of scientists and population the urgency for novel and quantitative tools for assessing the hydrologic impact of these type of plants, and trading between economic interests and ecologic concerns. In this contribution we propose an analytical framework that allows for the estimate of the streamflow availability for hydropower production and the selection of the run-of-river plant capacity, as well as the assessment of the related profitability and environmental impacts. The method highlights the key role of the streamflow variability in the design process, by showing the significance control of the coefficient of variation of daily flows on the duration of the optimal capacity of small run-of-river plants. Moreover, the analysis evidences a gap between energy and economic optimizations, which may result in the under-exploitation of the available hydropower potential at large scales. The disturbances to the natural flow regime produced between the intake and the outflow of run-of-river power plants are also estimated within the proposed framework. The altered hydrologic regime, described through the probability distribution and the correlation function of streamflows, is analytically expressed as a function of the natural regime for different management strategies. The deviations from pristine conditions of a set of hydrologic statistics are used, jointly with an economic index, to compare environmental and economic outcomes of alternative plant

    2005-01-01

    Rising concerns about the depletion of fossil fuels and climate change have led to the search for new energy sources. This paper outlines the mission of the Canadian Hydrogen Association, which is to build on Canada's energy resource base and expertise in hydrogen technologies in order to deploy sustainable hydrogen energy systems. Basic strategies needed to develop hydrogen systems in Canada were outlined, with specific reference to the establishment of low cost energy sources with low life-cycle emissions. The current hydrogen infrastructure produces marginal life-cycle emissions benefits, particularly when compared with improvements in technologies expected in the next 10 years. It was noted that regional development of hydrogen systems was likely to be an effective strategy, due to high transportation costs. Several potential locations were discussed for the development of a hydrogen energy infrastructure. Opportunities arising from hydrogen vehicle penetration of consumer markets and the broad commercialization of fuel cells were examined. Feasible transition strategies were reviewed, to be built in the near term around pathways such as hydrogen internal combustion engines and fuel cell vehicles designed for high-value niche applications. Strategies addressing the preparation of the market to express the value proposition for hydrogen were discussed, with reference to the fact that the existing energy market places no value on environmental factors. Several recommendations were made to conclude the discussion, and included: the necessity of government action to establish national goals; the creation of a stakeholder base for hydrogen systems; a government and industry partnership towards the development of a near-term commercialization plan; and the establishment of a long-term direction for the development of hydrogen systems in terms of advancing technology and public education. refs., tabs., figs

    2006-01-01

    The Commission has presented a thematic strategy on air pollution and has completed an Impact Assessment, which describes the costs and benefits for the member states. The thematic strategy is to result in a revised air quality directive as well as a revised NEC-directive that determines maximum emissions for a number of air pollution components, the so-called emission ceilings. The air pollution components include sulphur dioxide (SO 2 ), nitrogen oxide (NO X ), volatile organic compounds (NMVOC), ammonia (NH 3 ) and particulate matters (PM 2,5 ). The thematic strategy draws up targets for reductions of the Danish emissions for these components, which have to be met by 2020. These reductions will contribute to a lowering of PM 2,5 concentrations both in Denmark and in neighbouring countries. The concentration of PM 2,5 in the air includes both primary particles that come from emission of particles from e.g. incineration processes, and so-called secondary particles that are generated from emissions of NO X , SO 2 and NH 3 , and from releases from e.g. vegetation. A very large part of the secondary particles in the air in Denmark stems from emissions of these components in the rest of Europe. A very important condition for a reduction in the concentration of PM 2,5 in the air is thus a reduction of the emissions of these components in all of Europe. (au)

    2011-01-01

    Optimal combined cycle gas turbine power plants characterized by minimum specific annual cost values are here determined for wide ranges of market conditions as given by the relative weights of capital investment and operative costs, by means of a non-linear mathematical programming model. On the other hand, as the technical optimization allows identifying trends in the system behavior and unveiling optimization opportunities, selected functional relationships are obtained as the thermodynamic optimal values of the decision variables are systematically linked to the ratio between the total heat transfer area and the net power production (here named as specific transfer area). A strategy for simplifying the resolution of the rigorous economic optimization problem of power plants is proposed based on the economic optima distinctive characteristics which describe the behavior of the decision variables of the power plant on its optima. Such approach results in a novel mathematical formulation shaped as a system of non-linear equations and additional constraints that is able to easily provide accurate estimations of the optimal values of the power plant design and operative variables. Research highlights: → We achieve relationships between power plants' economic and thermodynamic optima. → We achieve functionalities among thermodynamic optimal values of decision variables. → The rigorous optimization problem is reduced to a non-linear equations system. → Accurate estimations of power plants' design and operative variables are obtained.

    The paper presents the Project `Inter-disciplinary Analysis of Successful Implementation of Energy Efficiency in Industry, Commerce and Service`. Based on empirical case studies in Germany, Denmark, Austria and Switzerland, the interdisciplinary approach combines techno-economical variables from traditional barrier analyses with new socio-economic and socio-psychological aspects. It is the objective to gain a broader understanding of successful implementation processes in industrial enterprises. The positive examples include energy conservation measures within the context of individual success stories as well as efficiency programmes. The project examines the interdependencies between boundary conditions and the features and dynamics of the internal change processes analysed. It identifies main actors inside and outside of the company, the crucial determinants of their energy related behaviour, and influence factors suitable for energy policy use. The project derives first typical patterns of social innovation and organisational development. Generalizing the findings in order to contribute to holistic policy recommendations, the project puts emphasis on instruments of economic and social marketing strategies to promote cooperative energy efficiency initiatives.

  17. Effect of multiple-feedstock strategy on the economic and environmental performance of thermochemical ethanol production under extreme weather conditions

    International Nuclear Information System (INIS)

    Kou, Nannan; Zhao, Fu

    2011-01-01

    Current US transportation sector mainly relies on liquid hydrocarbons derived from petroleum and about 60% of the petroleum consumed is from areas where supply may be disturbed by regional instability. This has led to serious concerns on energy security and global warming. To address these issues, numerous alternative energy carriers have been proposed. Among them, second generation biofuel is one of the most promising technologies. Gasification-based thermochemical conversion will bring flexibility to both feedstock and production sides of a plant, thus presents an attractive technical route to address both the energy security and global warming concerns. In this paper, thermochemical ethanol production using multiple-feedstock (corn stover, municipal solid waste, and wood chips) is simulated using Aspen Plus and compared with the single-feedstock scenario, in terms of economic performances, life cycle greenhouse gas (GHG) emissions and survivability under extreme weather conditions. For a hypothetical facility in southwest Indiana it is found that multiple-feedstock strategy improves the net present value by 18% compared to single-feedstock strategy. This margin is increased to 57% when effects of extreme weather conditions on feedstock supply are considered. Moreover, multiple-feedstock fuel plant has no potential risk of bankruptcy during the payback period, while single-feedstock fuel plant has a 75% chance of bankruptcy. Although the multiple-feedstock strategy has 26% more GHG emission per liter of ethanol produced than the single-feedstock strategy, the trend is reversed if feedstock supply disruption is taken into account. Thus the idea of multiple-feedstock strategy is proposed to the future thermo chemical biofuel plants.

    Wolfová, M; Wolf, J

    2013-09-01

    The objective of the present review was (i) to survey different approaches for choosing the complex of traits for which economic values (EVs) are calculated, (ii) to call attention to the proper definition of traits and (iii) to discuss the manner and extent to which relationships among traits have been considered in the calculation of EVs. For this purpose, papers dealing with the estimation of EVs of traits in livestock were reviewed. The most important reasons for incompatibility of EVs for similar traits estimated in different countries and by different authors were found to be inconsistencies in trait definitions and in assumptions being made about relationships among traits. An important problem identified was how to choose the most appropriate criterion to characterise production or functional ability for a particular class of animals. Accordingly, the review covered the following three topics: (i) which trait(s) would best characterise the growth ability of an animal; (ii) how to define traits expressed repeatedly in subsequent reproductive cycles of breeding females and (iii) how to deal with traits that differ in average value between sexes or among animal groups. Various approaches that have been used to solve these problems were discussed. Furthermore, the manner in which diverse authors chose one or more traits from a group of alternatives for describing a specific biological potential were reviewed and commented on. The consequences of including or excluding relationships among economically important traits when estimating the EV for a specific trait were also examined. An important conclusion of the review is that, for a better comparability and interpretability of estimated EVs in the literature, it is desirable that clear and unique definitions of the traits, complete information on assumptions used in analytical models and details on inter-relationships between traits are documented. Furthermore, the method and the model used for the genetic

    This work presents an algorithm control strategy denominated enthalpy economizer. The objective of this algorithm strategy is to determine the adequate fractions of outside and return air flowrates entering a cooling coil based on the analysis of the outside, return and supply air enthalpies, rather than on the analysis of the dry bulb temperatures. The proposed algorithm predicts the actual opening position of the outside and return air dampers in order to provide the lower mixing air enthalpy. First, the psychometrics properties of the outside and return air are calculated from actual measurements of the dry and wet bulb temperatures. Then, three distinct cases are analyzed: the enthalpy of the outside air is lower than the enthalpy of the supply air (free cooling); the enthalpy of the outside air is higher than the enthalpy of the return air; the enthalpy of the outside air is lower than the enthalpy of the return air and higher than the temperature of the supply air. Different outside air conditions were selected in order to represent typical weather data of Brazilians cities, as well as typical return air conditions. It was found that the enthalpy control strategy could promote an opportunity for energy savings mainly during mild nights and wintertime periods as well as during warm afternoons and summertime periods, depending on the outside air relative humidity. The proposed algorithm works well and can be integrated in some commercial automation software to reduce energy consumption and electricity demand. (author)

    The purpose of this study was to determine the cost for prevention and treatment of pressure ulcers from a hospital perspective and to identify the least resource-intensive pressure ulcer prevention strategy. Cost analyses were examined from a hospital perspective using direct costs. The study was carried out alongside a prospective cohort study on the incidence and risk factors for pressure ulcers. Two large teaching hospitals in the Netherlands with (partly) opposing approaches in prevention, a technological versus a human approach, were analyzed. The main outcome measures were resource use, costs of preventive measures and treatment, and pressure ulcer incidence in both hospitals. Pressure ulcer prevention through a predominantly technical approach resulted in a similar incidence rate as prevention through a predominantly human approach. However, the technical approach was considerably less expensive.

    The Environmental Protection Agency has estimated that as many as 20,000 lung cancer deaths per year in the United States can be attributed to exposure to radon gas. The report evaluates alternative strategies for motivating people to test for radon gas in their homes and to mitigate if necessary. Specifically, two separate radon information and awareness programs were evaluated, one targeted to the general population in the Washington, D.C. area and the other to home buyers in the Boulder, Colorado area. The results suggest that a home buyer program is likely to be far more effective in terms of effective remediation to reduce home radon levels than a program aimed at the general population. The report discusses the empirical findings and develops a recommendation for increasing the effectiveness of radon awareness and mitigation programs

    In social science, laboratory experiment with human subjects' interaction is a standard test-bed for studying social processes in micro level. Usually, as in physics, the processes near equilibrium are suggested as stochastic processes with time-reversal symmetry (TRS). To the best of our knowledge, near equilibrium, the breaking time symmetry, as well as the existence of robust time anti-symmetry processes, has not been reported clearly in experimental economics till now. By employing Markov transition method to analysis the data from human subject 2x2 Games with wide parameters and mixed Nash equilibrium, we study the time symmetry of the social interaction process near Nash equilibrium. We find that, the time symmetry is broken, and there exists a robust time anti-symmetry processes. We also report the weight of the time anti-symmetry processes in the total processes of each the games. Evidences in laboratory marketing experiments, at the same time, are provided as one-dimension cases. In these cases, time anti-symmetry cycles can also be captured. The proposition of time anti-symmetry processes is small, but the cycles are distinguishable.

    Full Text Available SUMMARYAquaculture is one of the worldwide economic activities which has grown in the last 30 years at an annual rate of 9-10.0 %. Poultry, pork, lamb and beef meat production have increased only at an annual rate of 3.0 % in the same period, and in the last five years has decreased due to aviar fever and other viral difficulties. While aquaculture growth takes place in far away countries as China near by countries as Costa Rica, Honduras, Brazil and Chile keeps the same tendency. As far as Mexico´s aquaculture is concerned, it has grown steadily, missing, even its way out. On the one hand fish catches do not grow since the middle of the 80´s when fish production reached 1.5 million tones. On the other hand aquaculture in fresh waters and in sea waters are almost staging due to the loss of authority and governmental management capacity to make decisions. The recently elected federal government which will take office next December 1st, has on its hands the opportunity to favor aquaculture production and doing so, to develop Mexican coastal and rural areas.

    In an intelligent energy system, ''smart grid'' and ''smart market'' must go hand in hand (Aichele et al., 2014). Changes to the legal framework, especially the German Renewable Energies Act (EEG), aim at bringing in line the requirement for increased generation of renewable energy with the market and system integration of renewable energies (see Schwarz, 2014). This determines whether the operation of a modern renewable energy plant has both the maximisation of profits (smart market) as well as the easing of the higher-order grid (smart grid) as its goal or whether it is only geared towards one aspect. The agricultural biogas producer is the focus of this interdisciplinary paper. He can either use the electrical energy generated by his plant himself in an economically orientated way or design the supply to the upstream grid in a way that is advantageous for the grid through the increased flexibility of generation and consumption. Through a two-stage simulation of the impact on the grid and the operational performance, the differences with regards to the strain on the grid and the financial losses to the farmer are quantified. If is clearly shown that none of the legislative and regulatory incentive schemes favour a mode of operation that is advantageous for the grid.

    In the face of imminent climate change, reform concepts that are based on energy conservation are bound to prevail over other approaches. One such concept is that of Least Cost Planning (LCP). LCP aims at an unbiased choice among the options on the supply side (power plants, networks) and those on the demand side (energy conservation and substitution programmes). While today LCP is often discussed in a rather abbreviated sense as a concept for corporate strategies of power supply companies, the present paper develops it as a new concept for public control of power supply companies. An example of US American practice is analysed to determine to what extent the concept of LCP is compatible, in principle and practice, with a control system over power supply companies. This is used to develop elements for the reform of the German control system which would provide the economic dimension to the power supply companies' task of efficient energy utilisation. (orig.)

    Full Text Available Summary Objective: The authors performed an economic assessment of opioids currently being used for control of postoperative pain relating to the surgical treatment of cancer (fentanyl and sufentanil within the Brazilian Unified Health System (SUS, in the Portuguese acronym. Method: The assessment was based on the perspective of the government, in order to collaborate with the promotion of effectiveness in public policies of health, and to optimize the allocation of public resources into health. A cost-effectiveness analysis was performed using data collected from the Brazilian Unified Health System and information from literature review, in order to build a decision tree on the alternatives for control of postoperative pain related to cancer treatment among adult patients. The outcomes considered were: effectiveness of postoperative analgesia and occurrence of nausea and vomit in the 48 hour period after surgery, and additional 24-hour cycles in patient follow-up. A univariate sensitivity analysis was conducted in order to verify robustness of the model estimated. Results: Literature review showed a limited number of studies directly comparing fentanyl and sufentanil for control of postoperative pain. The adoption of sufentanil (cost = U$ 25.72 / outcome = 1.6 VAS points was dominant in relation to the use of fentanyl (cost = U$ 32.58 / outcome = 2.6 VAS points. The estimated model showed robustness in relation to changes in the parameters analyzed. Conclusion: Sufentanil presented higher cost-effectiveness ratio in relation to fentanyl for control of postoperative pain in surgeries related to cancer treatment among adult patients in the Brazilian Unified Health System.

  18. Pharmaco-economic evaluation of antibiotic therapy strategies in DRG-based healthcare systems - a new approach

    2010-11-01

    Full Text Available Abstract The cost of treatments especially in conditions where multiresistant bacteria are involved are a major issue in times where in most developed countries in the world payment systems based on diagnoses-related-groups (DRG are in place. There is great evidence that especially the length of stay in hospital (LOS, the time in the intensive care unit (ICU-days and the hours of mechanical ventilation (HMV are major cost drivers. While established methods of pharmacoeconomical analyses focus on the efficiency of drugs from healthcare system perspective, these data are often not sufficient for improving treatment strategies in a given hospital context. We developed a system that allows the analysis of patients with severe infections on the basis of routine data that is also used for reimbursement. These data contain a lot of information concerning the clinical conditions. By using the ICD-coding we developed an algorithm which allows the detection of patients with infections and gives information on the potential financial outcome of these patients. By using the analysis it is possible to identify subsets of infections and the patient records that had a potentially negative DRG-result, i.e. the costs are higher than the reimbursement. When identified the patient records undergo a peer review, where the clinical situation and the antibiotic therapy are reviewed by medical experts. In case simulations it is possible to find out if a different therapeutic approach, e.g. by different choices in initial (empirical antibiotic treatment would have caused other outcomes. Data driven analyses together with peer reviews of patient records are a useful tool to examine antibiotic treatment strategies and to establish changes that again can be reviewed on a regular basis. Doing this a continous improvement process can be established in hospitals which can lead to a better balance of clinical and economical outcomes in patients with severe infections

    Climate changes on the Mongolian Plateau are creating new challenges for the households and communities of the region. Much of the existing research on household choices in response to climate variability and change focuses on environmental risks and stresses. In contrast, our analysis highlights the importance of taking into account environmental and economic opportunities in explaining household adaptation choices. We surveyed over 750 households arrayed along an ecological gradient and matched across the national border in Mongolia and the Inner Mongolia Autonomous Region, China, asking what changes in livelihoods strategies households made over the last ten years, and analyzed these choices in two broad categories of options: diversification and livestock management. We combined these data with remotely sensed information about vegetation growth and self-reported exposure to price fluctuations. Our statistical results showed that households experiencing lower ecological and economic variability, higher average levels of vegetation growth, and with greater levels of material wealth, were often those that undertook more actions to improve their conditions in the face of variability. The findings have implications both for how interventions aimed at supporting ongoing choices might be targeted and for theory construction related to social adaptation. (letter)

    Due to increasing public health concerns that food animals could be reservoirs for antibiotic resistant organisms, calls for reduced current antibiotic use on farms are growing. Nevertheless, it is challenging for farmers to perform this reduction without negatively affecting technical and economic performance. As an alternative, improved management practices based on biosecurity and vaccinations have been proven useful to reduce antimicrobial use without lowering productivity, but issues with insufficient experimental design possibilities have hindered economic analysis. In the present study a quasi-experimental approach was used for assessing the economic impact of reduction of antimicrobial use coupled with improved management strategies, particularly biosecurity strategies. The research was performed on farrow-to-finish pig farms in Flanders (northern region of Belgium). First, to account for technological progress and to avoid selection bias, propensity score analysis was used to compare data on technical parameters. The treatment group (n=48) participated in an intervention study whose aim was to improve management practices to reduce the need for use of antimicrobials. Before and after the change in management, data were collected on the technical parameters, biosecurity status, antimicrobial use, and vaccinations. Treated farms were matched without replacement with control farms (n=69), obtained from the Farm Accountancy Data Network, to estimate the difference in differences (DID) of the technical parameters. Second, the technical parameters' DID, together with the estimated costs of the management intervention and the price volatility of the feed, meat of the finisher pigs, and piglets served as a basis for modelling the profit of 11 virtual farrow-to-finish pig farms representative of the Flemish sector. Costs incurred by new biosecurity measures (median +€3.96/sow/year), and new vaccinations (median €0.00/sow/year) did not exceed the cost reduction

    Facing tight resource constraints, conservation organizations must allocate funds available for habitat protection as effectively as possible. Often, they combine spatially referenced economic and biodiversity data to prioritize land for protection. We tested how sensitive these prioritizations could be to differences in the spatial grain of these data by demonstrating how the conclusion of a classic debate in conservation planning between cost and benefit targeting was altered based on the available information. As a case study, we determined parcel-level acquisition costs and biodiversity benefits of land transactions recently undertaken by a nonprofit conservation organization that seeks to protect forests in the eastern United States. Then, we used hypothetical conservation plans to simulate the types of ex ante priorities that an organization could use to prioritize areas for protection. We found the apparent effectiveness of cost and benefit targeting depended on the spatial grain of the data used when prioritizing parcels based on local species richness. However, when accounting for complementarity, benefit targeting consistently was more efficient than a cost targeting strategy regardless of the spatial grain of the data involved. More pertinently for other studies, we found that combining data collected over different spatial grains inflated the apparent effectiveness of a cost targeting strategy and led to overestimation of the efficiency gain offered by adopting a more integrative return-on-investment approach. © 2014 Society for Conservation Biology.

    In patients at risk of surgical site infection (SSI), there is evidence that an antimicrobial barrier dressing (Acticoat* ) applied immediately post-procedure is effective in reducing the incidence of infection. The objective of this study was to assess when it is appropriate to use an antimicrobial barrier dressing rather than a post-operative film dressing, by evaluating the net cost and budget impact of the two strategies. An economic model was developed, which estimates expected expenditure on dressings and the expected costs of surgical site infection during the initial inpatient episode, based on published literature on the pre-discharge costs of surgical infection and the efficacy of an antimicrobial barrier dressing in preventing SSI. At an SSI risk of 10%, an antimicrobial barrier dressing strategy is cost neutral if the incidence of infection is reduced by at least 9% compared with a post-operative film dressing. At 35% efficacy, expenditure on dressings would be higher by £30,760 per 1000 patients, and the cost of treating infection would be lower by £111,650, resulting in a net cost saving of £80,890. The break-even infection risk for cost neutrality is 2.6%. Although this cost analysis is based on published data, there are limitations in methodology: the model is dependent on and subject to the limitations of the data used to populate it. Further studies would be useful to increase the robustness of the conclusions, particularly in a broader range of surgical specialties. A strategy involving the use of an antimicrobial barrier dressing in patients at moderate (5-10%) or high (>10%) risk of infection appears reasonable and cost saving in light of the available clinical evidence.

    Slums are densely populated, neglected parts of cities where housing and living conditions are exceptionally poor. In situ slum upgrading, at its basic level, involves improving the physical environment of the existing area, such as improving and installing basic infrastructure like water, sanitation, solid waste collection, electricity, storm water drainage, access roads and footpaths, and street lighting, as well as home improvements and securing land tenure. To explore the effects of slum upgrading strategies involving physical environment and infrastructure interventions on the health, quality of life and socio-economic wellbeing of urban slum dwellers in low and middle income countries (LMIC). Where reported, data were collected on the perspectives of slum dwellers regarding their needs, preferences for and satisfaction with interventions received. We searched for published and unpublished studies in 28 bibliographic databases including multidisciplinary (for example Scopus) and specialist databases covering health, social science, urban planning, environment and LMIC topics. Snowballing techniques included searching websites, journal handsearching, contacting authors and reference list checking. Searches were not restricted by language or publication date. We included studies examining the impact of slum upgrading strategies involving physical environment or infrastructure improvements (with or without additional co-interventions) on the health, quality of life and socio-economic wellbeing of LMIC urban slum dwellers. Randomised controlled trials (RCTs), controlled before and after studies (CBAs) and interrupted time series (ITS) were eligible for the main analysis. Controlled studies with only post-intervention data (CPI) and uncontrolled before and after (UBA) studies were included in a separate narrative to examine consistency of results and to supplement evidence gaps in the main analysis. Two authors independently extracted data and assessed risk of bias

    Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). Tofacitinib is approved in the United States for use in adults with moderately to severely active RA and an inadequate response or intolerance to methotrexate. To (a) evaluate, using an economic model, the treatment costs of an RA strategy including tofacitinib, compared with adalimumab, etanercept, certolizumab and tocilizumab biologic RA treatment strategies, which are commonly prescribed in the United States, and (b) assess the economic impact of monotherapy and combination therapy in patients who had an inadequate response to methotrexate therapy (MTX-IR analysis) and to combination therapy in patients who had an inadequate response to a tumor necrosis factor inhibitor (TNF-IR analysis). A transparent, Excel-based economic model with a decision-tree approach was developed to evaluate costs over a 1- and 2-year time horizon. The model compared tofacitinib 5 mg twice a day (BID) either as monotherapy or in combination with MTX with similarly labeled biologic therapies. Response to treatment was modeled as American College of Rheumatology (ACR) 20/50/70 response. ACR20 represented clinical response and determined whether patients continued therapy. ACR response rates at 6-month intervals were sourced from prescribing information and safety event rates from a published meta-analysis. Following an adverse event or a lack of response to treatment, it was assumed that 75% of patients switched to the next line of treatment (first to abatacept and then to rituximab). The perspective was that of a U.S. payer. Costs were reported in 2015 U.S. dollars and included drug wholesale acquisition costs, monitoring, drug administration, and treatment for minor and serious adverse events. The patient population eligible for treatment was based on the total number of members (i.e., RA and non-RA) in a payer organization; members with RA treated with biologic therapies were estimated using

    More than any other GCC states, political and economic foundation linkages between Dubai and Qatar have been great factors that could result in similar economic development. Shared oil boom experiences and early political cooperation brought several significant opportunities where Qatar and Dubai can manage similar economic development. Yet, Dubai’s government was able to develop and diversify its economy, thus becoming one of the largest economic hubs in the world, while Qatar wasn’t able to...

    In Denmark, guidelines on low back pain management are currently being implemented; in association with this, a clinical trial is conducted. A health economic evaluation is carried out alongside the clinical trial to assess the cost-effectiveness of an extended implementation strategy to increase the general practitioners' adherence to the guidelines. In addition to usual dissemination, the extended implementation strategy is composed of visits from a guideline facilitator, stratification tools, and feedback on guideline adherence. The aim of this paper is to provide the considerations on the design of the health economic evaluation. The economic evaluation is carried out alongside a cluster randomised controlled trial consisting of 60 general practices in the North Denmark Region. An expected 1,200 patients between the age of 18 and 65 years with a low back pain diagnosis will be enrolled. The economic evaluation comprises both a cost-effectiveness analyses and a cost-utility analysis. Effectiveness measures include referral to secondary care, health-related quality of life measured by EQ-5D-5L, and disability measured by the Roland Morris disability questionnaire. Cost measures include all relevant additional costs of the extended implementation strategy compared to usual implementation. The economic evaluation will be performed from both a societal perspective and a health sector perspective with a 12-month time horizon. It is expected that the extended implementation strategy will reduce the number of patients referred to secondary care. It is hypothesised that the additional upfront cost of extended implementation will be counterbalanced by improvements in clinical practice and patient-related outcomes, thereby rendering the extended implementation strategy cost-effective.

    A report commissioned by the German Ministry of Health recommends to the existing scheme for calculating risk-adjusted transfers to sickness funds supplement with the IPHCC+RxGroups method. The method is based on inpatient diagnoses and prescribed drugs as health status measures deduced from prior use. The present study investigates the sickness fund's expected net return from gaming based on the drug component of the risk adjuster. The study explores three possible strategies using the RxGroups method. For the stimulations, insurees are assigned to additional indications or to higher valued RxGroups within the same indication. Then, costs and financial benefits attributable to the altered drug use are estimated and compared with the status quo. The study uses 2000 and 2001 sample data of more than 370,000 insurees of Germany's company-based sickness funds system (BKK). While upgrading increases overall costs, it can be beneficial for the individual sickness funds. Their net return crucially depends on the number of sickness funds gaming the system: the more participating in the game, the smaller is the average net return. Moreover, not participating often is even worse, which in turn points to a prisoner's dilemma. When extending the risk adjustment scheme in social health insurance, the German legislator should take into account the perverse incentives of risk adjusters such as the described prescription drug model.

    To test the effectiveness of behavioral economics strategies for increasing vegetable intake, variety, and liking among children residing in homes receiving food assistance. A randomized controlled trial with data collected at baseline, once weekly for 6 weeks, and at study conclusion. Family homes. Families with a child (9-12 years) will be recruited through community organizations and randomly assigned to an intervention (n = 36) or control (n = 10) group. The intervention group will incorporate a new behavioral economics strategy during home dinner meal occasions each week for 6 weeks. Strategies are simple and low-cost. The primary dependent variable will be child's dinner meal vegetable consumption based on weekly reports by caregivers. Fixed independent variables will include the strategy and week of strategy implementation. Secondary dependent variables will include vegetable liking and variety of vegetables consumed based on data collected at baseline and study conclusion. Mean vegetable intake for each strategy across families will be compared using a mixed-model analysis of variance with a random effect for child. In additionally, overall mean changes in vegetable consumption, variety, and liking will be compared between intervention and control groups.

    Early peanut introduction (EPI) in the first year of life is associated with reduced risk of developing peanut allergy in children with either severe eczema and/or egg allergy. However, EPI recommendations differ among countries with formal guidelines. Using simulation and Markov modeling over a 20-year horizon to attempt to explore optimal EPI strategies applied to the US population, we compared high-risk infant specific IgE peanut screening (US/Canadian) with the Australiasian Society for Clinical Immunology and Allergy (Australia/New Zealand) (ASCIA) and the United Kingdom Department of Health (UKDOH) published EPI approaches. Screening peanut skin testing of all children with early onset eczema and/or egg allergy before in-office peanut introduction was dominated by a no-screen approach, in terms of number of cases of peanut allergy prevented, QALY's, and healthcare costs, though screening resulted in a slightly lower rate of allergic reactions to peanut per-patient in high-risk children. Considering costs of peanut allergy in high-risk children, the per-patient cost of early introduction without screening over the model horizon was $6,556.69 (95%CI, $6,512.76-$6,600.62), compared with a cost of $7,576.32 (95%CI, $7,531.38-$7,621.26) for skin test screening prior to introduction. From a US societal perspective, screening prior to introduction cost $654,115,322 and resulted in 3,208 additional peanut allergy diagnoses. Both screening and non-screening approaches dominated deliberately delayed peanut introduction. A no-screening approach for EPI has superior health and economic benefits in terms of number of peanut allergy cases prevented, QALY's, and total health care costs compared to screening and in-office peanut introduction.

    Suicide and non-fatal suicide behavior (NFSB) are significant problems faced by most countries. The objective of this research is to quantify the economic cost of suicide and NFSB in the Australian workforce and to examine the potential impact of introducing a workplace suicide prevention intervention to reduce this burden. The analysis used the best available suicide data, a well-established costing methodology, and a proven workplace intervention. In 2014, 903 workers died by suicide, 2303 workers harmed themselves resulting in full incapacity, and 11,242 workers harmed themselves resulting in a short absence from work. The present value of the economic cost of suicide and NFSB is estimated at $6.73 billion. Our analysis suggests the economic benefit of implementing a universal workplace strategy would considerably outweigh the cost of the strategy. For every one dollar invested, the benefits would be in excess of $1.50 ($1.11-$3.07), representing a positive economic investment. All variations of the key parameter hold the positive benefit-cost ratio. Rates of suicide and NFSB are far too high in Australia and elsewhere. More needs to be done to reduce this burden. Although workplace strategies are appropriate for those employed, these interventions must be used within a multifaceted approach that reflects the complex nature of self-harming behavior.

    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.

    Little research has been conducted into the cost and prevention of self-harm in the workplace. To quantify the economic cost of self-harm and suicide among New South Wales (NSW) construction industry (CI) workers and to examine the potential economic impact of implementing Mates in Construction (MIC). Direct and indirect costs were estimated. Effectiveness was measured using the relative risk ratio (RRR). In Queensland (QLD), relative suicide risks were estimated for 5-year periods before and after the commencement of MIC. For NSW, the difference between the expected (i.e., using NSW pre-MIC [2008-2012] suicide risk) and counterfactual suicide cases (i.e., applying QLD RRR) provided an estimate of potential suicide cases averted in the post-MIC period (2013-2017). Results were adjusted using the average uptake (i.e., 9.4%) of MIC activities in QLD. Economic savings from averted cases were compared with the cost of implementing MIC. The cost of self-harm and suicide in the NSW CI was AU $527 million in 2010. MIC could potentially avert 0.4 suicides, 1.01 full incapacity cases, and 4.92 short absences, generating annual savings of AU $3.66 million. For every AU $1 invested, the economic return is approximately AU $4.6. MIC represents a positive economic investment in workplace safety.

  3. Strategy for the expansion of renewable energies. An investigation of the pricing strategy of the Renewable Energy Law from the viewpoint of an evolutionary cybernetic theory of economic policy

    Schlueter, Fabian

    2015-01-01

    This publication reports on how the steadily increasing costs caused by the Renewable Energy Law (EEG) have brought the German strategy for the expansion of renewable energies under criticism. According to theories of regulatory economic policy, which state that politico-economic incentives of this kind must necessarily result in an inefficient allocation of scarce resources, this cost increase can be interpreted as a direct consequence of the price intervention. The present publication takes a critical stance on this viewpoint, developing for its purpose a new position on regulatory policy referred to as the evolutionary cybernetic theory of economic policy. It starts out from the works of F.A. von Hayek, which it then takes a significant step further however. The author argues that price interventions can be meaningful strategies of economic policy as long as they are aimed at a temporary initiation of market development towards sustainability and efficiency. Based on this model conception of a shrewd pricing strategy the publication undertakes an analysis from the perspective of regulatory policy of the German subsidisation of renewable energies. In the process it not only reveals errors in design of the EEG but also makes a proposal for an amendment that could be effective in cutting through the present price dynamics. In presenting its recommendation of a self-steering expansion policy the publication not only contributes to the further development of an evolutionary cybernetic theory of economic policy but addresses the urgent problem of how to wisely use regulatory policy to create pricing strategies which serve the expansion of renewable energies.

    The energy national strategy contemplates the execution of the climatic change law, which establishes that at 2024 the 35% of the electric generation should be given by means of the clean sources use (non originators of greenhouse gases). In the energy national strategy 2012-2026 three possible scenarios to execute this goal are proposed, in two of them is considered the participation of the nuclear energy, the economic implications of these three scenarios are analyzed in this study as well as the reduction in emissions that would derive of their implementation.

    Borderline Personality Disorder (BPD) is characterized by severe and persistent impairments in interpersonal functioning. Given the complexity of social interactions, studying the interactive behavior of BPD patients is challenging. One way to implement both tight experimental control and realistic, externally valid settings is to use game-theoretical experiments. This review discusses findings from economic exchange studies in BPD against the background of game-theoretical literature. BPD patients do not seem to derive utility from mutual cooperation with others and appear not to "forgive" a partner's unfairness. By pursuing a strategy of negative reciprocity, BPD patients seem to act mostly "rationally" and in their own self-interest. Their "grim trigger strategy" resembles the theoretical ideal of the rational and self-interested agent homo economicus. Finally, we summarize how research findings from economics and clinical psychiatry may be mutually enriching and propose new research ideas in this fascinating field. Copyright © 2016 Elsevier Ltd.

To develop a tool for calculating cost effectiveness of chlamydia control programmes at a local, national, or international level. An economic and mathematical modelling study with cost effectiveness analysis. Costs were restricted to those of screening and partner notification from the perspective of the NHS and excluded patient costs, the costs of reinfection, and costs of complications arising from initial infection. England. Population Individuals eligible for the National Chlamydia Screening Programme. Cost effectiveness of National Chlamydia Screening Programme in 2008-9 (as cost per individual tested, cost per positive diagnosis, total cost of screening, number screened, number infected, sex ratio of those tested and treated). Comparison of baseline programme with two different interventions-(i) increased coverage of primary screening in men and (ii) increased efficacy of partner notification. In 2008-9 screening was estimated to cost about £46.3m in total and £506 per infection treated. Provision for partner notification within the screening programme cost between £9 and £27 per index case, excluding treatment and testing. The model results suggest that increasing male screening coverage from 8% (baseline value) to 24% (to match female coverage) would cost an extra £22.9m and increase the cost per infection treated to £528. In contrast, increasing partner notification efficacy from 0.4 (baseline value) to 0.8 partners per index case would cost an extra £3.3m and would reduce the cost per infection diagnosed to £449. Increasing screening coverage to 24% in men would cost over six times as much as increasing partner notification to 0.8 but only treat twice as many additional infections. In the English National Chlamydia Screening Programme increasing the effectiveness of partner notification is likely

    In 2008, corn grain prices rose $115/t of DM above the 2005 average. Such an increase creates tight marginal profits for small (profit losses by growing more corn silage and reducing corn grain purchases. This study applies the Integrated Farm Systems Model to 1 small and 1 medium-sized New York State dairy farm to predict 1) sediment and P loss impacts from expanding corn fields, 2) benefits of no-till or cover cropping on corn fields, and 3) alternatives to the economic challenge of the current farming system as the price ratio of milk to corn grain continues to decline. Based on the simulation results, expanding corn silage production by 3% of the cultivated farm area increased sediment and sediment-bound P losses by 41 and 18%, respectively. Implementing no-till controlled about 84% of the erosion and about 75% of the sediment-bound P that would have occurred from the conventionally tilled, expanded corn production scenario. Implementing a conventionally tilled cover crop with the conventionally tilled, expanded corn production scenario controlled both erosion and sediment-bound P, but to a lesser extent than no-till corn with no cover crop. However, annual farm net return using cover crops was slightly less than when using no-till. Increasing on-farm grass productivity while feeding cows a high-quality, high-forage diet and precise dietary P levels offered dual benefits: 1) improved farm profitability from reduced purchases of dietary protein and P supplements, and 2) decreased runoff P losses from reduced P-levels in applied manure. Moreover, alternatives such as growing additional small grains on marginal lands and increasing milk production levels demonstrated great potential in increasing farm profitability. Overall, it is crucial that conservation measures such as no-till and cover cropping be implemented on new or existing corn lands as these areas often pose the highest threat for P losses through runoff. Although alternatives that would likely provide

    Full Text Available This article presents a study of technological development that occurs in association with learning processes in SME of fruits growers. The goal of the article is to answer the following question: How SME of fruits growers conduct their operations to fit the strategy of export? To seek answers, we performed a qualitative multi-case study, four companies being studied. Data were collected using semi-structured interviews. To ensure the quality of fruits exports, there is an international certification called GLOBALGAP, which, after having obtained makes it possible to overcome barriers of entry for products in other countries. Three of the four companies studied are certified. Throughout the certification process, companies had to promote learning and intense changes in their daily work. These changes involved the use of new technologies, such as mode and type of application of chemical fertilizers and pesticides. With the learning process occurred as the acquisition of new knowledge about agricultural management techniques more suitable to produce fruit of better quality, awareness of the need for greater care in personal hygiene and first aid training. Data analysis found that, to carry out the export strategy, companies had to seek development and improvement of its manpower, with the secondary gain improvement of production processes, including fruits that are directed to Brazilian market, which also showed greater improvement in quality.

    Countries of Southern Europe are currently suffering from severe socio-economic pain resulting from high debt levels and austerity measures which constrain investment in innovation-based recovery strategies that are essential for entry into a long-term sustainable period of increasing employment and wealth creation. Young university-educated people are particularly innovative, and hence vital to the development of such strategies, but employment opportunities are poor and many are forced to seek employment that neither profits from their training nor satisfies their justified career expectations, or to emigrate. They are the 'lost generation'. A strategy is proposed here for the creation of Pipelines for New Chemicals, national centre-network partnerships for the discovery-synthesis of new chemicals obtained though harvesting new biological diversity, and their exploitation to develop new medicines, agrochemicals, materials, and other products and applications. The goal is to create new regional motors of economic growth and development, by harnessing the knowledge, motivation and innovation potential of the excellently educated young people of Europe to catalyse the development of new small, medium and large enterprises centred around novel chemicals, and the value chains that will evolve with them, and thereby develop a powerful sector of sustainable growth in employment and social and economic prosperity in Southern Europe. © 2014 Society for Applied Microbiology and John Wiley & Sons Ltd.

    The decision of a firm to make investments on petroleum fields depends on the expected economic performance and on the firm economics context and on country economic and regulatory constraints. Traditionally, the Net Present Value (NPV) has being used for decision criterion as a measure of profitability of investments. The other indicators are used to help investment decision, because, according to the priorities established by the firm, only one indicator may not be sufficient. On this paper we will show production strategies considering a set of economic indicators: NPV, actualized Np, Return on investment (ROI), Equivalent Present Value (EPV), Cost Benefit, and NPV/Np ratio. The use of different economic indicators permits capture different aspects from in a decision process, i.e., each indicator or a set of economic measures may result in a different perspective, that will influence the decision manager. It is important to emphasize the use of more than one indicators may been advantageous, mainly on oil reservoirs that present high level of uncertainties. The presented application is related to the choice of the production strategy of a petroleum field. The indicators are used to evaluate the performance of the field and of the production and injection wells. A sensitivity analysis was performed in order to show the use of indicators on uncertain scenarios (oil prices, taxes, etc). The results show that the use of various indicators proportionate a decision taking with a lesser risk, as well as makes possible to capture other project characteristics which not always can be represented by the traditional use of NPV.

    The relations between the economic development and energy consumption is explained and their complexity is pointed out. The development of the official energy prognoses since 1973 and the development of economic growth and energy consumption from 1951-1976 show that these two developments had been linked together during certain periods but that the coefficient of elasticity shows a falling trend in the long term. The parameters determining the relation between economic growth and energy consumption are discussed: energy prices, capacity load, investments and technological innovations. At the same time the limits of a possible decoupling are demonstrated.

    Flavonoids are a group of important naturally occurring polyphenolic compounds with a wide range of biological effects. In this study, a sensitive liquid chromatography tandem mass spectrometry method was developed to simultaneously determine multiple active flavonoids, including quercetin (Que), kaempferol (Kae), apigenin (Api), isorhamnetin (Iso), luteolin (Lut), and naringenin (Nar), in rat plasma. To achieve a satisfied peak shape and LC separation, formic acid with the concentration between 0.05 and 0.2%, or in some case 5%, was generally used to acidify the LC mobile phase in reported studies. Here we found that even 0.05% formic acid could lead to strong mass signal suppression, and the absence of formic acid could reverse the signal suppression but cause serious peak tailing. There is an irreconcilable contradiction between liquid chromatography (LC) and mass spectrometry (MS). In order to simultaneously satisfy LC and MS, LC mobile phase with 0.00075% formic acid and post column mobile phase adjustment with 0.0677% ammonium solution in isopropanol were applied. Compared with the conventional method with mobile phase containing 0.05% formic acid, the mass signal response of Que, Kae, Api, Iso, Lut, Nar, and Oka increased 26.2, 18.6, 13.6, 23.5, 17.5, 15.6 and 15.4 fold, respectively. In addition, the post column mobile phase addition exhibited the better peak shape for the reduction of analytes longitudinal diffusion. The method has been fully validated according to FDA guidelines within the linear range between 0.328 ng mL⁻¹ and 168 ng mL⁻¹, and successfully applied to a pilot pharmacokinetic study of rats after administering 5.43 g kg⁻¹ Pollen of Brassica campestris.

    Particulate air pollution is becoming a serious public health concern in urban cities in India due to air pollution-related health effects associated with disability-adjusted life years (DALYs) and economic loss. To obtain the quantitative result of health impact of particulate matter (PM) in most populated Mumbai City and most polluted Delhi City in India, an epidemiology-based exposure-response function has been used to calculate the attributable number of mortality and morbidity cases from 1991 to 2015 in a 5-year interval and the subsequent DALYs, and economic cost is estimated of the health damage based on unit values of the health outcomes. Here, we report the attributable number of mortality due to PM 10 in Mumbai and Delhi increased to 32,014 and 48,651 in 2015 compared with 19,291 and 19,716 in year 1995. And annual average mortality due to PM 2.5 in Mumbai and Delhi was 10,880 and 10,900. Premature cerebrovascular disease (CEV), ischemic heart disease (IHD), and chronic obstructive pulmonary disease (COPD) causes are about 35.3, 33.3, and 22.9% of PM 2.5 -attributable mortalities. Total DALYs due to PM10 increased from 0.34 million to 0.51 million in Mumbai and 0.34 million to 0.75 million in Delhi from average year 1995 to 2015. Among all health outcomes, mortality and chronic bronchitis shared about 95% of the total DALYs. Due to PM 10 , the estimated total economic cost at constant price year 2005 US$ increased from 2680.87 million to 4269.60 million for Mumbai City and 2714.10 million to 6394.74 million for Delhi City, from 1995 to 2015, and the total amount accounting about 1.01% of India's gross domestic product (GDP). A crucial presumption is that in 2030, PM 10 levels would have to decline by 44% (Mumbai) and 67% (Delhi) absolutely to maintain the same health outcomes in year 2015 levels. The results will help policy makers from pollution control board for further cost-benefit analyses of air pollution management programs in Mumbai and Delhi.

    Full Text Available Human African Trypanosomiasis (HAT, a disease caused by protozoan parasites transmitted by tsetse flies, is an important neglected tropical disease endemic in remote regions of sub-Saharan Africa. Although the determination of the burden of HAT has been based on incidence, mortality and morbidity rates, the true burden of HAT goes beyond these metrics. This study sought to establish the socio-economic burden that households with HAT faced and the coping strategies they employed to deal with the increased burden.A mixed methods approach was used and data were obtained through: review of hospital records; structured interviews (152; key informant interviews (11; case narratives (12 and focus group discussions (15 with participants drawn from sleeping sickness patients in the south western HAT foci in Kenya. Quantitative data were analysed using descriptive statistics while qualitative data was analysed based on emerging themes.Socio-economic impacts included, disruption of daily activities, food insecurity, neglect of homestead, poor academic performance/school drop-outs and death. Delayed diagnosis of HAT caused 93% of the affected households to experience an increase in financial expenditure (ranging from US$ 60-170 in seeking treatment. Out of these, 81.5% experienced difficulties in raising money for treatment resorting to various ways of raising it. The coping strategies employed to deal with the increased financial expenditure included: sale of agricultural produce (64%; seeking assistance from family and friends (54%; sale/lease of family assets (22%; seeking credit (22% and use of personal savings (17%.Coping strategies outlined in this study impacted negatively on the affected households leading to further food insecurity and impoverishment. Calculation of the true burden of disease needs to go beyond incidence, mortality and morbidity rates to capture socio-economic variables entailed in seeking treatment and coping strategies of HAT

    The aim of this study was to review and critically assess the health economics literature on post-treatment follow-up for adult cancer survivors. A systematic search was performed using PubMed, EMBASE and the Cochrane Library. The Consolidated Health Economic Evaluation Reporting Standards checklist was adopted to assess the quality of the included studies. Thirty-nine articles met the eligibility criteria. Around two thirds of the studies addressed the most common cancers (i.e., breast, colorectal, cervical and lung); 21 were based on a single clinical study, while the rest were modeling papers. All types of economic evaluations were represented other than cost-benefit analysis. The overall quality was generally high with an average proportion of 74% of checklist criteria fulfilled. The cost-effectiveness results supported the current trend towards less intensive, primary care-based and risk-adapted follow-up schemes.

    Two studies investigated relationships between traditional indicators of acculturation, cultural distance, acculturation strategies, and basic dimensions of personality as they pertain to psychological adjustment among Hispanic students. Although personality characteristics have been shown to be important determinants of psychological well-being, acculturation research has put less emphasis on the role of personality in the well-being of immigrants. Hierarchical regression analysis showed that basic dimensions of personality such as extraversion and neuroticism were strongly related to psychological adjustment. Acculturation strategies did not mediate the effect of personality variables, but cultural resistance made a small, independent contribution to the explanation of some aspects of negative psychological adjustment. The implications of the results were discussed.

  2. An economic evaluation of preclinical testing strategies compared to the compulsory scrapie flock scheme in the control of classical scrapie.

    Directory of Open Access Journals (Sweden)

    Lisa Boden

    Full Text Available Cost-benefit is rarely combined with nonlinear dynamic models when evaluating control options for infectious diseases. The current strategy for scrapie in Great Britain requires that all genetically susceptible livestock in affected flocks be culled (Compulsory Scrapie Flock Scheme or CSFS. However, this results in the removal of many healthy sheep, and a recently developed pre-clinical test for scrapie now offers a strategy based on disease detection. We explore the flock level cost-effectiveness of scrapie control using a deterministic transmission model and industry estimates of costs associated with genotype testing, pre-clinical tests and the value of a sheep culled. Benefit was measured in terms of the reduction in the number of infected sheep sold on, compared to a baseline strategy of doing nothing, using Incremental Cost Effectiveness analysis to compare across strategies. As market data was not available for pre-clinical testing, a threshold analysis was used to set a unit-cost giving equal costs for CSFS and multiple pre-clinical testing (MT, one test each year for three consecutive years. Assuming a 40% within-flock proportion of susceptible genotypes and a test sensitivity of 90%, a single test (ST was cheaper but less effective than either the CSFS or MT strategies (30 infected-sales-averted over the lifetime of the average epidemic. The MT strategy was slightly less effective than the CSFS and would be a dominated strategy unless preclinical testing was cheaper than the threshold price of £6.28, but may be appropriate for flocks with particularly valuable livestock. Though the ST is not currently recommended, the proportion of susceptible genotypes in the national flock is likely to continue to decrease; this may eventually make it a cost-effective alternative to the MT or CSFS.

    This final technical report of the study contains the important equations and results of the above mentioned project. The main aim of the study was to show the importance of renewable energy in Nordrhein-Westfalen regarding its possible contribution to the energy supply as well as the reduction of carbon dioxide emissions, caused by the convertion of energy. Considering the energy sources photovoltaic, solar heating, wind and biomass, an economically oriented energy mix of renewable energy systems is developed, which describes the most economical combination of renewable energy sources and its production costs in dependence on the converted energy. In this connection a regional disaggregated estimation of the theoretical possible maximum contribution of the single renewable energy sources to the energy supply in the communities of Nordrhein-Westfalen is investigated. Basing on this estimation and on the technical datas of commerical manufactured systems, converting the energy sources sun, wind and biomass, the technical possibilities for an extension of the renewable energy are determined for every community. The result of the examinations shows, that the energy supply in Nordrhein-Westfalen could by based in future on barely a fourth by using renewable energy sources, on barely a third by using energy more efficient and on nearly the half by using fossil and nuclear energy sources. The costs however, which would be connected with an extension of renewable energy sources according to the suggested energy mix, can economical not be accepted in the further future. (orig./UA) [de

    Full Text Available An important challenge in terms of smoothing excessive exchange rate volatility under the conditions of flexible exchange rate arrangement is optimization of the communication strategy of the country’s monetary regulator. Over the past two decades, communication (information support has become an increasingly important aspect of monetary policy. Communication enables influence of the volatility of financial markets, improvement of the predictability of monetary policy, and helps to achieve macroeconomic objectives. Nevertheless, as of today, consensus on the issue into what the optimal strategy of the central bank communication is has not been reached, either in Ukraine, nor in developed countries yet. Considering the abovementioned, the methodical approaches to improve the central bank’s communication strategies, based on the use of its verbal interventions in the context of smoothing out excessive cyclical volatility of exchange rates of the national currency, are determined in this article. It is suggested to consider the growth of the factor “information signal/information noise” as a criterion of the central bank’s optimal communication strategy. It is proved that the monetary regulator’s main task should be the continual provision of information concerning a fundamentally justified level of the exchange rate and the level of deviation of the actual rate of the national currency from its fundamental-equilibrium level, as of a given time, to the national foreign exchange market participants. The methodological approach to the improvement of information support of forecasting fundamentally specified value of the national currency is outlined.

    Research purpose: The objective of the research was to investigate the relation between adultlearners’ cognitive learning strategies (measured by the examination preparation inventoryand their psychosocial employability attributes (measured by the employability attributesscale. Motivation for the study: Recent research has made important progress in understanding thenotions of cognitive learning styles in learning and psychosocial employability attributes insustaining individuals’ employability in the contemporary world of work. However, researchon how adult learners’ cognitive learning strategies influence the psychosocial attributes theyneed to manage and sustain their employability has been lacking. Research approach, design and method: A quantitative cross-sectional survey design wasused, involving a stratified proportional random sample of 1102 predominantly early careerblack female undergraduate level adult learners. The participants were enrolled for distancelearning studies in the economic and management sciences field at a South African highereducation institution. Main findings: Canonical correlation and multiple regression analysis indicated the abstracttheoretical and factual practical cognitive learning strategies as useful predictors of theparticipants’ overall level of psychosocial employability attributes and especially their levelsof career self-management and proactivity. Practical/managerial implications: Learning practitioners should strive to integrate cognitivelearning strategies in the design of learning and assessment activities in order to fosterthe psychosocial employability attributes adult learners need to manage their continuedemployability in the contemporary workplace. Contribution: The study contributes new insights to the employability and learning andeducation literature. The results may potentially inform formal learning and assessmentdesign in order to improve adult learners’ learning performance and employability.

    Full Text Available The article explores the prospects for the development of Ukraine’s anti-crisis strategy in the current conditions of aggravation of the socio-economic situation. The urgency of the researched subject – namely, the study of the potential directions for the development of the anti-crisis tools of Ukrainian state policy – is determined primarily by the seriousness of the problem, which should be overcome by means of these methods. The purpose of the article is to identify promising tools and mechanisms for an anti-crisis policy that can make a significant contribution to improving the current state of the socio-economic sphere in Ukraine. Its subject is anti-crisis tools and instruments, which could be used in Ukrainian scenario. It is noted that our state is at the stage of the permanent crisis and suffers from the consequences of both global and local crisis phenomena. The scientific novelty of the article is determined by the combination of economic, social, political, and legal approaches to the study of the current state of the Ukrainian economy. The methodology of the research is formed by the combination of economic and political methods of scientific activities, which are based on the principles of objectivism and systematic approach. The findings of scientific research and recommendations of some Ukrainian scientists regarding the necessary anti-crisis tools are considered as the sources for the article. The results of the study show that Ukraine suffers from a series of systemic problems and challenges, which are the main threat to the stability of the national economy. Among the most influential of them we can identify the low level of incomes of citizens, which is associated with the devaluation of the national currency and the increase in utility tariffs; high level of unemployment; shortage of foreign and domestic investments; the decline in production and exports, caused both by military operations in the Donbas and the loss

    As part of its commitments to the Regional Greenhouse Gas Initiative (RGGI), the State of Maryland, USA, auctions emission permits to electric utilities, creating revenue that can be used to benefit consumers and the environment. This paper explores the CO 2 emissions reductions that may be possible by allocating some of that revenue to foster efficiency improvements in the residential sector's use of natural gas. Since these improvements will require changes to the capital stock of houses and end use equipment, efficiency improvements may be accompanied by economic and ancillary health impacts, both of which are quantified in this paper.

It was conducted with an assumption that the branding of the 2010 FIFA World Cup as „Africa‟s Time‟, „Africa‟s moment‟, and „Africa‟s turn‟ to the benefit of the continent would be viewed with pessimism, at least by the (Egypt, Algeria, Kenya, Ethiopia, Ghana and Nigeria major African regional economic players, as an event that did not benefit the continent as a whole but South Africa and the Southern African Development Community (SADC region. This article used phenomenological strategy under qualitative methods whereby face to face interviews were conducted from a sample drawn from the pool of diplomatic community and the staff of relevant Non-Governmental Organisations (NGOs and Inter-Governmental Organisations (IGOs in Addis Ababa, Ethiopia. The results revealed that an event was a tremendous boost to the pride and confidence of Africa and its people. Credit should be given to South Africa for taking the leading role in marketing an event as African and not as South African. Such marketing strategy did not only ensure African ownership but instilled the sense of African pride.

    2014-11-01

    This paper investigates whether environmental management is an economically sustainable business. While firms invest in green production and green supply chain activities with the primary purpose of reducing their environmental impact, the reciprocal relationships with economic performance need to be clarified. Would firms and suppliers adjust their environmental strategies if the higher economic value that environmental management generates is reinvested in greening actions? We found out that environmental management positively influences economic performance as second order (long term) target, to be reached conditioned by higher environmental performance; in addition, firms can increase their performance if they reinvest the higher economic value gained through environmental management in green practices: While investing in environmental management programs is a short term strategy, economic rewards can be obtained only with some delays. Consequently, environmental management is an economically sustainable business only for patient firms. In the evaluation of these reciprocal relationships, we discovered that green supply chain initiatives are more effective and more economically sustainable than internal actions.

    Green and sustainable remediation (GSR) has become a global trend in the contaminated land remediation field. Growing numbers of countries have adopted GSR procedures published in regulatory and/or technical guidance. China is fast becoming one of the largest remediation markets in the world, and is beginning to engage with GSR. Among other efforts, a taskforce is currently developing the first Chinese technical standard on GSR. This paper presents the context positioning and development of a sustainable remediation assessment indicator set for China. This sustainability indicator set was formed based on existing sustainable remediation guidelines and literature. LCA was used to evaluate environmental impacts, and the results combined with social and economic appraisal via MCA. The indicator set was applied to a remediation 'mega-site' in China. The results showed that compared to excavation and landfill, an alternative treatment strategy of soil washing, thermal desorption and S/S brought about relatively less waste generation, better worker safety, and preferable local impacts, leading to higher scores in the environmental and social-economic domains. However, the social-economic scores were limited by a lack of public engagement. The results of the case study have shown that the indicator set is valid, with lessons learnt and suggestions for improvement discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

  1. An Integrated Carbon Policy-Based Interactive Strategy for Carbon Reduction and Economic Development in a Construction Material Supply Chain

    Directory of Open Access Journals (Sweden)

    Liming Zhang

    2017-11-01

    Full Text Available Carbon emissions from the construction material industry have become of increasing concern due to increasingly urbanization and extensive infrastructure. Faced with serious atmospheric deterioration, governments have been seeking to reduce carbon emissions, with carbon trading and carbon taxes being considered the most effective regulatory policies. Over time, there has been a global consensus that integrated carbon trading/carbon tax policies are more effective in reducing carbon emissions. However, in an integrated carbon reduction policy framework, balancing the relationship between emission reductions and low-carbon benefits has been found to be a critical issue for governments and enterprises in both theoretical research and carbon emission reduction practices. As few papers have sought to address these issues, this paper seeks to reach a trade-off between economic development and environmental protection involving various stakeholders: regional governments which aim to maximize social benefits, and producers who seek economic profit maximization. An iterative interactive algorithmic method with fuzzy random variables (FRVs is proposed to determine the satisfactory equilibrium between these decision-makers. This methodology is then applied to a real-world case to demonstrate its practicality and efficiency.

  2. Different habitus: different strategies in teaching physics? Relationships between teachers' social, economic and cultural capital and strategies in teaching physics in upper secondary school

    With environmental awareness in the societies of today, political steering documents emphasize that all education should include sustainable development. But it seems to be others competing ideals for teaching physics, or why do the physics teachers teach as they do? Physics teachers in secondary school in Sweden have generally, been focused on facts and a strong link with scientific theories and concepts. In general, the curriculum sway the teaching, a standard text book in physics is used, the teaching is organized according to the book and the teacher deals with and demonstrates typical tasks on the whiteboard and group work is common for special issues related to tasks from the textbook or elaborating. The aim with this study is to analyze why physics teachers in upper secondary school choose to teach energy as they do. Data emerging from a questionnaire focused on indicators of the teachers' cultural and economic assets, or capital, according to the work of Pierre Bourdieu's sociology. Especially his concept on life styles and habitus provide a tool for analysis. We focus on physics teachers' positions in the social space, dispositions and standpoints towards the ideal way to teach physics in upper secondary school (n = 268). Our response rate is 29 % and due to the low response rate a non response bias analysis was made. In our analysis we primarily sought for groups, with a cluster analysis based on the teaching practice, revealed common features for both what and how they teach and three different teaching types emerged. Then we reconstructed the group habitus of the teachers by analyzing dispositions and standpoints and related those to the specific polarization of sacred values, that is struggles about the natural order (doxa) in the social space of science education, which is a part of and has boundaries to dominating fields like the natural sciences and the political fields (curriculum etc.). Three teacher-groups' habituses are described and analyzed

    Helicobacter pylori may cause many gastrointestinal problems in developing countries such as Iran. We aimed to analyze the cost- effectiveness and cost- utility of the test-and-treat and empirical treatment strategies in managing Helicobacter pylori infection. This was a Markov based economic evaluation. Effectiveness was defined as the symptoms free numbers and QALYs in 100,000 hypothetical adults. The sensitivity analysis was based on Monte Carlo approach. In the test- and- treat strategy, if the serology is the first diagnostic test vs. histology, the cost per symptoms free number would be 291,736.1 Rials while the cost per QALYs would be 339,226.1 Rials. The cost per symptoms free number and cost per QALYs when the 13 C-UBT was used as the first diagnostic test vs. serology was 1,283,200 and 1,492,103 Rials, respectively. In the empirical strategy, if histology is used as the first diagnostic test vs. 13 CUBT, the cost per symptoms free numbers and cost per QALYs would be 793,234 and 955,698 Rials, respectively. If serology were used as the first diagnostic test vs. histology, the cost per symptoms free and QALYs would be 793,234 and 368941 Rials, respectively. There was no significant and considerable dominancy between the alternatives and the diagnostic tests.

    This study tended to apply biorefinery of indigenous microbes to the fermentation of target-product generation through a novel control strategy. A novel strategy for co-producing two valuable homopoly(amino acid)s, poly(ε-l-lysine) (ε-PL) and poly(l-diaminopropionic acid) (PDAP), was developed by controlling pH and dissolved oxygen concentrations in Streptomyces albulus PD-1 fermentation. The production of ε-PL and PDAP got 29.4 and 9.6gL(-1), respectively, via fed-batch cultivation in a 5L bioreactor. What is more, the highest production yield (21.8%) of similar production systems was achieved by using this novel strategy. To consider the economic-feasibility, large-scale production in a 1t fermentor was also implemented, which would increase the gross profit of 54,243.5USD from one fed-batch bioprocess. This type of fermentation, which produces multiple commercial products from a unified process is attractive, because it will improve the utilization rate of raw materials, enhance production value and enrich product variety.

    2010-01-01

    The present biofuel policies in the European Union primarily stimulate 1st generation biofuels that are produced based on conventional food crops. They may be a distraction from lignocellulose based 2nd generation biofuels - and also from biomass use for heat and electricity - by keeping farmers' attention and significant investments focusing on first generation biofuels and the cultivation of conventional food crops as feedstocks. This article presents two strategies that can contribute to the development of 2nd generation biofuels based on lignocellulosic feedstocks. The integration of gasification-based biofuel plants in district heating systems is one option for increasing the energy efficiency and improving the economic competitiveness of such biofuels. Another option, biomass co-firing with coal, generates high-efficiency biomass electricity and reduces CO 2 emissions by replacing coal. It also offers a near-term market for lignocellulosic biomass, which can stimulate development of supply systems for biomass also suitable as feedstock for 2nd generation biofuels. Regardless of the long-term priorities of biomass use for energy, the stimulation of lignocellulosic biomass production by development of near term and cost-effective markets is judged to be a no-regrets strategy for Europe. Strategies that induce a relevant development and exploit existing energy infrastructures in order to reduce risk and reach lower costs, are proposed an attractive complement the present and prospective biofuel policies.

    Child Health Days (CHDs) are increasingly used by countries to periodically deliver multiple maternal and child health interventions as time-limited events, particularly to populations not reached by routine health services. In countries with a weak health infrastructure, this strategy could be used to reach many underserved populations with an integrated package of services. In this study, we estimate the incremental costs, impact, cost-effectiveness, and return on investment of 2 rounds of CHDs that were conducted in Somalia in 2009 and 2010. We use program costs and population estimates reported by the World Health Organization and United Nations Children's Fund to estimate the average cost per beneficiary for each of 9 interventions delivered during 2 rounds of CHDs implemented during the periods of December 2008 to May 2009 and August 2009 to April 2010. Because unstable areas were unreachable, we calculated costs for targeted and accessible beneficiaries. We model the impact of the CHDs on child mortality using the Lives Saved Tool, convert these estimates of mortality reduction to life years saved, and derive the cost-effectiveness ratio and the return on investment. The estimated average incremental cost per intervention for each targeted beneficiary was $0.63, with the cost increasing to $0.77 per accessible beneficiary. The CHDs were estimated to save the lives of at least 10,000, or 500,000 life years for both rounds combined. The CHDs were cost-effective at $34.00/life year saved. For every $1 million invested in the strategy, an estimated 615 children's lives, or 29,500 life years, were saved. If the pentavalent vaccine had been delivered during the CHDs instead of diphtheria-pertussis-tetanus vaccine, an additional 5000 children's lives could have been saved. Despite high operational costs, CHDs are a very cost-effective service delivery strategy for addressing the leading causes of child mortality in a conflict setting like Somalia and compare

  10. When There Is No Welfare: The Income Packaging Strategies of Mothers Without Earnings or Cash Assistance Following an Economic Downturn

    Directory of Open Access Journals (Sweden)

    Kristin S. Seefeldt

    2015-11-01

    Full Text Available The 1996 welfare reform law sought to reformulate single mothers’ income package, replacing cash welfare checks with paychecks. However, many single mothers have not been able to do that and have neither earnings nor cash assistance. Among a sample of single mothers in Los Angeles and southeast Michigan, we find that when single mothers lose jobs and do not receive cash assistance, they package income from a variety of sources (such as other public assistance programs and informal child support, find others in their social networks to pay their bills, or move in with others. However, their income packaging strategies are fraught with challenges. Benefits from certain public programs are difficult to secure; financial assistance from friends and family members can quickly vanish, particularly if a partner is deported or jailed; and doubling up with others often leads to living in crowded and unsafe conditions.

  11. The impact of European balancing rules on wind power economics and on short-term bidding strategies

    2014-01-01

    Wind power represents a significant percentage of the European generation mix and this will increase to fulfill the renewable energy targets. Different balancing rules are applied to wind power among the countries; for instance, to what extent wind power producers (WPPs) are responsible for the energy imbalances and how those imbalances are penalized. This paper discusses those different rules and evaluates their effects on WPP bidding strategies. To do so, a quantitative analysis is presented for an offshore wind farm, considering the differences in the balancing rules and prices of Belgium, Denmark, Germany and the Netherlands. The quantitative approach consists of a stochastic optimization model that maximizes the profits of a WPP by trading in different markets (day-ahead and intraday) and computes the final energy delivered. The model considers uncertainties of most important parameters such as wind energy forecasts and prices at different time frames. The results show that the imbalance pricing design and the allocation of balance responsibility significantly affect WPP’ revenues. Additionally, WPPs deviate differently from the expected energy depending on the balancing rules, which can impact the system. Furthermore, these balancing rules should be considered with other market regulations, such as the design of support schemes. - Highlights: • European countries apply different imbalance pricing rules. • The allocation of balance responsibility to wind power varies between the countries. • A stochastic optimization model is used to compare the effect of balancing rules. • Balancing rules have an important impact on wind generators bidding strategies. • Balancing rules have also an effect on the system imbalances

    2015-03-01

    Full Text Available A simple but economically feasible refining method to treat and re-use biodiesel wash-water was developed. In detail, microfiltration (MF through depth-filtration configuration was used in different hybrid modules. Then, the treated wash-water was mixed with clean water at different ratios, re-used for biodiesel purification and water-washing efficiency was evaluated based on methyl ester purity analysis. The findings of the present study revealed that depth-filtration-based MF combined with sand filtration/activated carbon separation and 70% dilution rate with fresh water not only achieved standard-quality biodiesel product but also led to up to 15% less water consumption after two rounds of production operations. This would be translated into a considerable reduction in the total volume of fresh water used during the operation process and would also strengthen the environmental-friendly aspects of the biodiesel production process for wastewater generation was obviously cut by the same rate as well.

    2011-01-01

    The GMS countries, supported by the Asian Development Bank, have adopted a holistic, multidimensional approach to strengthen infrastructural linkages and facilitate cross border trade through (i) the establishment of a trans-boundary road connecting two economic nodes across marginalised areas, followed by 2) facilitation of environmentally and socially sound investments in these newly connected areas as a means to develop livelihoods. The North-South Economic Corridor is currently in its second phase of development, with investment opportunities to be laid out in the NSEC Strategy and Action Plan (SAP). It targets the ecologically and culturally sensitive border area between PR China's Yunnan Province, Northern Lao PDR, and Thailand. A trans-boundary, cross-sectoral Strategic Environmental Assessment was conducted to support the respective governments in assessing potential environmental and social impacts, developing alternatives and mitigation options, and feeding the findings back into the SAP writing process. Given the spatial dimension of corridor development-both with regard to opportunities and risks-particular emphasis was put in the application of spatial modelling tools to help geographically locate and quantify impacts as a means to guide interventions and set priorities.

    Highlights: • 3E impact of WTE derived from MSW were performed. • MSW treatment technologies significantly effects the economic and environmental benefits of WTE. • Different scenarios are conducted based on the waste projections and production. • Comprehensive discussion on the trade-off of both incineration and anaerobic digestion for MSWM. - Abstract: The utilisation of municipal solid waste (MSW) for energy production has been implemented globally for many decades. Malaysia, however, is still highly dependent on landfills for MSW management. Because of the concern for greenhouse gases (GHG) emission and the scarcity of land, Malaysia has an urgent need for a better waste management strategy. This study aims to evaluate the energy, economic and environmental (3E) impact of waste-to-energy (WTE) for municipal solid waste management. An existing landfill in Malaysia is selected as the case study for consideration to adopt the advanced WTE technologies including the landfill gas recovery system (LFGRS), incineration, anaerobic digestion (AD), and gasification. The study presented an interactive comparison of different WTE scenarios and followed by further discussion on waste incineration and AD as the two potential WTE options in Malaysia. The 3E assessment reveals incineration as the superior technology choice when the production of electricity and heat were considered; however, AD is found to be more favourable under the consideration of electricity production only

    2015-11-01

    This publication reports on how the steadily increasing costs caused by the Renewable Energy Law (EEG) have brought the German strategy for the expansion of renewable energies under criticism. According to theories of regulatory economic policy, which state that politico-economic incentives of this kind must necessarily result in an inefficient allocation of scarce resources, this cost increase can be interpreted as a direct consequence of the price intervention. The present publication takes a critical stance on this viewpoint, developing for its purpose a new position on regulatory policy referred to as the evolutionary cybernetic theory of economic policy. It starts out from the works of F.A. von Hayek, which it then takes a significant step further however. The author argues that price interventions can be meaningful strategies of economic policy as long as they are aimed at a temporary initiation of market development towards sustainability and efficiency. Based on this model conception of a shrewd pricing strategy the publication undertakes an analysis from the perspective of regulatory policy of the German subsidisation of renewable energies. In the process it not only reveals errors in design of the EEG but also makes a proposal for an amendment that could be effective in cutting through the present price dynamics. In presenting its recommendation of a self-steering expansion policy the publication not only contributes to the further development of an evolutionary cybernetic theory of economic policy but addresses the urgent problem of how to wisely use regulatory policy to create pricing strategies which serve the expansion of renewable energies.

    Successful adjustment to college is required for academic success. We investigated whether inflammatory bowel disease (IBD) activity affects this adjustment process. We created an online survey that included a Student Adaptation to College Questionnaire (SACQ), a general quality of life survey (SF-12), a disease-specific short IBD quality of life survey (SIBDQ), and disease activity indices. Undergraduate students across the United States were recruited via social media. Surveys were completed by 65 students with Crohn's disease (CD), 28 with ulcerative colitis, and 214 healthy students (controls). Disease-specific quality of life (SIBDQ results) correlated with IBD disease activity (rho = -0.79; P academic work (P academic challenges (P academically successful (P academics-especially among students with CD. Successful adjustment is important for academic success, affecting graduation rates and future economic success. Strategies to increase disease control and provide social and emotional support during college could improve adjustment to college and academic performance, and increase patients' potential.

    In this work we describe the development of a biopreservation strategy for fresh fish based on the use of bacteriocinogenic LAB of marine origin. For this purpose, two multibacteriocinogenic LAB strains, Lactobacillus curvatus BCS35 and Enterococcus faecium BNM58, previously isolated from fish and fish products were selected owing to their capability to inhibit the growth of several fish-spoilage and food-borne pathogenic bacteria. Two commercially important fish species were chosen, young hake (Merluccius merluccius) and megrim (Lepidorhombus boscii), and the specimens were acquired at the Marín (Pontevedra, Spain) retail fish market, after one night in the chilled hold of a near-shore fishing vessel. The biopreservation potential and the application strategies of these two LAB strains were first tested at a laboratory scale, where several batches of fresh fish were inoculated with: (i) the multibacteriocinogenic LAB culture(s) as protective culture(s); and/or (ii) their cell-free culture supernatant(s) as food ingredient(s), and (iii) the lyophilized bacteriocin preparation(s) as lyophilized food ingredient(s). All batches were stored in polystyrene boxes, permanently filled with ice at 0-2 °C, for 14 days. Microbiological analyses, as well as sensorial analyses, were carried out during the biopreservation trials. Subsequently, Lb. curvatus BCS35 was selected to up-scale the trials, and combinations of the three application methods were assayed. For this purpose, this strain was grown in a semi-industrial scale fermentor (150l) in modified MRS broth, and three batches of fresh fish were inoculated with the protective culture and/or food ingredient, and stored on ice in a chilled chamber at 0-2 °C at the Marín retail fish market for 14 days. Microbiological analyses were carried out during the storage period, showing that when Lb. curvatus BCS35 culture or the corresponding cell-free culture supernatant was used as protective culture or food ingredient

  2. ECOLOGICAL ECONOMICS VS ECONOMIC(AL ECOLOGY

    2015-10-01

    Full Text Available Currently world faces the dilemma – ecological economy or economic(al ecology. The researchers produce hundreds of surveys on the topic. However the analyses of recent most cited simulations had shown the diversity of results. Thus, for some states the Kuznets environmental curve has place, for others – no. Same could be said about different years for the same state. It provokes the necessity of drawing new group analyses to reveal the tendencies and relationships between economic and environmental factors. Most flexible and mirror factor of environmental sustainability is the volume of CO2 emissions. The econometric analysis was used for detecting the economic impact on this indicator at the global level and in the spectra of group of states depending on their income. The hypothesis of the existence of environmental Kuznets curve for the analysed data is rejected. Real GDP per capita impact on carbon dioxide emissions is considered only at the global level. The impact of openness of the economy is weak. Rejection happened also to the hypothesis that for the developed countries there is a reverse dependence between the environmental pollution and economic openness. Indicator “energy consumption per capita” impacts on greenhouse gas emissions only in countries with high income. Whereby it should be noted that the more developed a country is, the more elastic is this influence. These results have a potential usage for environmental policy regulation and climate strategy.

    Full Text Available Considerable effort is being made to reduce the primary energy consumption in buildings. As part of this effort, fuel cell systems are attracting attention as a new/renewable energy systems for several reasons: (i distributed generation system; (ii combined heat and power system; and (iii availability of various sources of hydrogen in the future. Therefore, this study aimed to develop an economic and environmental assessment model for selecting the optimal implementation strategy of the fuel cell system, focusing on building energy policy. This study selected two types of buildings (i.e., residential buildings and non-residential buildings as the target buildings and considered two types of building energy policies (i.e., the standard of energy cost calculation and the standard of a government subsidy. This study established the optimal implementation strategy of the fuel cell system in terms of the life cycle cost and life cycle CO2 emissions. For the residential building, it is recommended that the subsidy level and the system marginal price level be increased. For the non-residential building, it is recommended that gas energy cost be decreased and the system marginal price level be increased. The developed model could be applied to any other country or any other type of building according to building energy policy.

    High levels of sedentary behaviour (i.e., sitting) are a risk factor for poor health. With high levels of sitting widespread in desk-based office workers, office workplaces are an appropriate setting for interventions aimed at reducing sedentary behaviour. This paper describes the development processes and proposed intervention procedures of Stand More AT (SMArT) Work, a multi-component randomised control (RCT) trial which aims to reduce occupational sitting time in desk-based office workers within the National Health Service (NHS). SMArT Work consists of 2 phases: 1) intervention development: The development of the SMArT Work intervention takes a community-based participatory research approach using the Behaviour Change Wheel. Focus groups will collect detailed information to gain a better understanding of the most appropriate strategies, to sit alongside the provision of height-adjustable workstations, at the environmental, organisational and individual level that support less occupational sitting. 2) intervention delivery and evaluation: The 12 month cluster RCT aims to reduce workplace sitting in the University Hospitals of Leicester NHS Trust. Desk-based office workers (n = 238) will be randomised to control or intervention clusters, with the intervention group receiving height-adjustable workstations and supporting techniques based on the feedback received from the development phase. Data will be collected at four time points; baseline, 3, 6 and 12 months. The primary outcome is a reduction in sitting time, measured by the activPAL(TM) micro at 12 months. Secondary outcomes include objectively measured physical activity and a variety of work-related health and psycho-social measures. A process evaluation will also take place. This study will be the first long-term, evidence-based, multi-component cluster RCT aimed at reducing occupational sitting within the NHS. This study will help form a better understanding and knowledge base of facilitators and

    The goals of environmental legislation and associated regulations are to protect public health, natural resources, and ecosystems. In this context, monitoring programs should provide timely and relevant information so that the regulatory community can implement legislation in a cost-effective and efficient manner. The Safe Drinking Water Act (SDWA) of 1974 attempts to ensure that public water systems (PWSs) supply safe water to its consumers. As is the case with many other federal environmental statutes, SDWA monitoring has been implemented in relatively uniform fashion across the United States. In this three part series, spatial and temporal patterns in water quality data are utilized to develop, compare, and evaluate the economic performance of alternative place-based monitoring approaches to current monitoring practice. Part II: Several factors affect the performance of monitoring strategies, including: measurable objectives, required precision in estimates, acceptable confidence levels of such estimates, available budget for sampling. In this paper, we develop place-based monitoring strategies based on extensive analysis of available historical water quality data (1960-1994) of 19 Iowa community water systems. These systems supply potable water to over 350,000 people. In the context of drinking water, the objective is to protect public health by utilizing monitoring resources to characterize contaminants that are detectable, and are close to exceeding health standards. A place-based monitoring strategy was developed in which contaminants were selected based on their historical occurrence, rather than their appearance on the SDWA contaminant list.

Three sampling allocation models (linear, quadratic, and cubic) based on historic patterns in peak occurrence were developed and

    In vitro fertilization (IVF) with single embryo transfer (SET) has been proposed as a means of reducing multiple pregnancies associated with infertility treatment. All existing cost-effectiveness studies of IVF-SET have compared it with IVF with multiple embryo transfer but not with intrauterine insemination with gonadotropin stimulation (sIUI). We conducted a systematic review of studies of cost-effectiveness of IVF-SET versus IVF with double embryo transfer (DET). Further, we developed a health economy model that compared three strategies: (1) IVF-SET, (2) IVF-DET, and (3) sIUI. The decision analysis considered three cycles for each treatment option. IVF treatment was assumed to be a combination of cycles with transfer of fresh and frozen-thawed embryos. Probabilities used to populate the model were taken from published randomized clinical trials and observational studies. Cost estimates were based on average costs of associated procedures in Canada. The results of published studies on the cost-effectiveness of IVF-SET versus IVF-DET were not consistent. In our analysis, IVF-DET proved to be the most cost-effective strategy at $35,144/live birth, followed by sIUI at $66,960/live birth, and IVF-SET at $109,358/live birth. The results were sensitive both to the cost of IVF cycles and to the probability of live birth. This economic analysis showed that IVF-DET was the most cost-effective strategy of the options, and IVF-SET was the least cost-effective. The results in this model were insensitive to various probability inputs and to the costs associated with sIUI and IVF procedures.

    Full Text Available This article is aimed at analyzing Mexico’s attempts to overcome the obstacles that the new international context, shaped by the end of World War II (WWII and the beginning of the Cold War, posed for the country’s economic development plans. Drawing largely on new Mexican primary sources along with American, British, and multilateral organizations’ documents, this work will focus on the strategy that the Miguel Alemán administration (1946-1952 designed in order to adapt to the adverse conditions that the bipolar conflict generated for Latin America’s industrial developmental projects. This article will show that in spite of the adverse setting, the Alemán government was able to create and launch an ambitious plan for economic industrialization that implemented developmental measures on a large scale. In addition, this work will also show that a crucial ingredient for the initial success of Mexico’s economic strategy was the country’s capacity to attract economic aid and political support from Washington. Paradoxically, this happened at a time when the United States’ (US economic and political backing of Latin American developmental projects had become a scarce currency in the Western Hemisphere.Este artículo tiene como objetivo analizar los intentos de México para superar los obstáculos que el nuevo contexto internacional, dibujado por el final de la Segunda Guerra Mundial y por el comienzo de la Guerra Fría, planteó para los planes de desarrollo económico del país.

    The mission of the U.S. Geological Survey (USGS) in natural hazards is to develop and apply hazard science to help protect the safety, security, and economic well-being of the Nation. The costs and consequences of natural hazards can be enormous, and each year more people and infrastructure are at risk. USGS scientific research—founded on detailed observations and improved understanding of the responsible physical processes—can help to understand and reduce natural hazard risks and to make and effectively communicate reliable statements about hazard characteristics, such as frequency, magnitude, extent, onset, consequences, and where possible, the time of future events. To accomplish its broad hazard mission, the USGS maintains an expert workforce of scientists and technicians in the earth sciences, hydrology, biology, geography, social and behavioral sciences, and other fields, and engages cooperatively with numerous agencies, research institutions, and organizations in the public and private sectors, across the Nation and around the world. The scientific expertise required to accomplish the USGS mission in natural hazards includes a wide range of disciplines that this report refers to, in aggregate, as hazard science. In October 2010, the Natural Hazards Science Strategy Planning Team (H–SSPT) was charged with developing a long-term (10–year) Science Strategy for the USGS mission in natural hazards. This report fulfills that charge, with a document hereinafter referred to as the Strategy, to provide scientific observations, analyses, and research that are critical for the Nation to become more resilient to natural hazards. Science provides the information that decisionmakers need to determine whether risk management activities are worthwhile. Moreover, as the agency with the perspective of geologic time, the USGS is uniquely positioned to extend the collective experience of society to prepare for events outside current memory. The USGS has critical

  11. Struggles over patriarchal structural adjustment in Tanzania.

    Within the space of 7 years (1986-93), structural adjustment policies have contributed to a reversal of the gains in economic development achieved in Tanzania in the 1960s and 1970s. Structural adjustment policies have helped large-scale producers and ordinary citizens but have led to a decline in social services which is reflected in drops in primary school enrollment and increases in medical costs. Government revenues are absorbed by foreign debt servicing. The reduction of support for social services has increased women's work; bolstered gender division of labor; and reduced women's access to education, formal employment, and health services. On the other hand, increased participation in market-oriented activities has increased women's mobility and exposure to modern ideas. This has led to changing gender relations which on the positive side can lead to shared decision-making but on the negative side may cause men to abdicate their familial responsibilities. Women suffer, however, from a lack of investment in ways to lighten their household responsibilities and have lost their ability to control food production because of the shift to cash crop production for export. The combination of hard work, low income, and stress has taken a toll on women's health, and both the maternal mortality rate and incidence of HIV infections among teenage girls has increased. In response to this situation, Tanzanian women have formed the Tanzania Gender Networking Programme (TGNP) which seeks to empower women and transform society through such activities as education and training, research, and lobbying and networking. Workshops sponsored by the TGNP have resulted in recommendations for adoption of a people-centered development strategy.

    Full Text Available Several approaches to reduce the incidence of invasive cervical cancers exist. The approach adopted should take into account contextual factors that influence the cost-effectiveness of the available options.To determine the cost-effectiveness of screening strategies combined with a vaccination program for 10-year old girls for cervical cancer prevention in Vientiane, Lao PDR.A population-based dynamic compartment model was constructed. The interventions consisted of a 10-year old girl vaccination program only, or this program combined with screening strategies, i.e., visual inspection with acetic acid (VIA, cytology-based screening, rapid human papillomavirus (HPV DNA testing, or combined VIA and cytology testing. Simulations were run over 100 years. In base-case scenario analyses, we assumed a 70% vaccination coverage with lifelong protection and a 50% screening coverage. The outcome of interest was the incremental cost per Disability-Adjusted Life Year (DALY averted.In base-case scenarios, compared to the next best strategy, the model predicted that VIA screening of women aged 30-65 years old every three years, combined with vaccination, was the most attractive option, costing 2 544 international dollars (I$ per DALY averted. Meanwhile, rapid HPV DNA testing was predicted to be more attractive than cytology-based screening or its combination with VIA. Among cytology-based screening options, combined VIA with conventional cytology testing was predicted to be the most attractive option. Multi-way sensitivity analyses did not change the results. Compared to rapid HPV DNA testing, VIA had a probability of cost-effectiveness of 73%. Compared to the vaccination only option, the probability that a program consisting of screening women every five years would be cost-effective was around 60% and 80% if the willingness-to-pay threshold is fixed at one and three GDP per capita, respectively.A VIA screening program in addition to a girl vaccination

    2000-05-01

    According to current forecasts, greenhouse gas emissions from energy consumption by the commercial and industrial sector will increase from 11,000 kilotonnes to 16,000 kilotons between 1990 and 2015. During the same period electricity generated in British Columbia from fossil fuel combustion will have increased from five per cent to 26 per cent. Therefore, to reduce greenhouse gas emissions it will be imperative to find ways of significantly reducing the consumption of electricity, natural gas and petroleum products in both the commercial and industrial sectors. Increased application of energy conservation practices, energy efficiency improvements, fuel switching and the increased use of renewable energy sources come to mind as the most appropriate strategies to be considered, despite formidable barriers to implementation. Despite the existence of barriers, some progress is being made as indicated by codes and standards, financial incentives, educational and public awareness campaigns, and research and development programs. This report examines the barriers, the measures that have already been implemented to combat greenhouse gas emissions and the economic and environmental benefits that will accrue from these and other measures currently under development. The beneficial impact of increased investment in greenhouse gas emission reduction technologies on employment is emphasized. 24 refs., tabs., figs

  18. A comparison of the economic benefits of centralized and distributed model predictive control strategies for optimal and sub-optimal mine dewatering system designs

    Mine dewatering can represent up to 5% of the total energy demand of a mine, and is one of the mine systems that aim to guarantee safe operating conditions. As mines go deeper, dewatering pumping heads become bigger, potentially involving several lift stages. Greater depth does not only mean greater dewatering cost, but more complex systems that require more sophisticated control systems, especially if mine operators wish to gain benefits from demand response incentives that are becoming a routine part of electricity tariffs. This work explores a two stage economic optimization procedure of an underground mine dewatering system, comprising two lifting stages, each one including a pump station and a water reservoir. First, the system design is optimized considering hourly characteristic dewatering demands for twelve days, one day representing each month of the year to account for seasonal dewatering demand variations. This design optimization minimizes the annualized cost of the system, and therefore includes the investment costs in underground reservoirs. Reservoir size, as well as an hourly pumping operation plan are calculated for specific operating environments, defined by characteristic hourly electricity prices and water inflows (seepage and water use from production activities), at best known through historical observations for the previous year. There is no guarantee that the system design will remain optimal when it faces the water inflows and market determined electricity prices of the year ahead, or subsequent years ahead, because these remain unknown at design time. Consequently, the dewatering optimized system design is adopted subsequently as part of a Model Predictive Control (MPC) strategy that adaptively maintains optimality during the operations phase. Centralized, distributed and non-centralized MPC strategies are explored. Results show that the system can be reliably controlled using any of these control strategies proposed. Under the operating

    The Great Recession of 2007-2009 adversely affected the financial stability of the community-based mental health infrastructure in Ohio. This paper presents survey results of the type of adaptive strategies used by Ohio community-based mental health organizations to manage the consequences of the economic downturn. Results were aggregated into geographical classifications of rural, mid-sized urban, and urban. Across all groups, respondents perceived, to varying degrees, that the Great Recession posed a threat to their organization's survival. Urban organizations were more likely to implement adaptive strategies to expand operations while rural and midsized urban organizations implemented strategies to enhance internal efficiencies.

    improvements in BOD, SS and NH3-N were estimated as 36.2%, 27.7% and 29.2%, respectively. The net present value (i.e., economical-based environmental impact) becomes positive in the sixtieth year following the original government planning. We designed two scenarios for further comparison: (i) treatment efficiency improvement of pollution control facilities, and (ii) biogas-based power generation using livestock manure. If government budget is not a limiting factor, improving the efficiency of sewage treatment plants can make the occurrence of balance between payments and revenues (i.e., net present value in this study) three years earlier. For the biogas-based power generation scenario, if all pig farms with livestock number >2000 install the on-site power generation equipment, BOD will further improve by 9% and the time span of payback period will be shortened by 1 year. If all the manure waste from pig-farms is collected for subsequent electricity generation, the BOD river pollution index is estimated to improve to lightly-polluted category for more than half the length of Erhjen Creek. In short, water quality modelling technique not only can assess the contributions of related projects, but establish a practical pollution reduction strategy using cost-benefit analysis, which allows decision-maker to find a suitable pollution reduction plan to exhibit most benefits in river water quality.
