    The obstacles to bringing about consumer response to environmental dangers are particularly challenging for global problems like ozone depletion and the greenhouse effect. In this situation, there is the danger of what is commonly termed the tragedy of the commons, the ecological destruction that can occur from uncontrolled use of shared resources like the atmosphere. There is probably no country for which reductions in global warming provide an adequate economic incentive to reduce greenhouse gas emissions unilaterally, even though such action could yield substantial global benefits. From any one country's viewpoint, the costs of controlling emissions may exceed the benefits since, without international agreement, reductions achieved by one nation may be offset by another. Therefore, even though the entire world may be better off as a result of efforts to lower emissions, new economic incentives are necessary to lead the market to a socially efficient outcome. This paper describes the range of domestic and international policies that could be adopted to reduce emissions of greenhouse gases, and also discusses the results of modeling analyses of government actions that could reduce or increase such emissions

  2. Vaccines against drugs of abuse: a viable treatment option?

    Drug addiction is a chronically relapsing brain disorder. There is an urgent need for new treatment options for this disease because the relapse rate among drug abusers seeking treatment is quite high. During the past decade, many groups have explored the feasibility of using vaccines directed against drugs of abuse as a means of eliminating illicit drug use as well as drug overdose and neurotoxicity. Vaccines work by inducing drug-specific antibodies in the bloodstream that bind to the drug of abuse and prevent its entry into the brain. The majority of work in this area has been conducted with vaccines and antibodies directed against cocaine and nicotine. On the basis of preclinical work, vaccines for cocaine and nicotine are now in clinical trials because they can offer long-term protection with minimal treatment compliance. In addition, vaccines and antibodies for phencyclidine, methamphetamine and heroin abuse are currently under development. An underlying theme in this research is the need for high concentrations of circulating drug-specific antibodies to reduce drug-seeking and drug-taking behaviour when the drug is repeatedly available, especially in high doses. Although vaccines against drugs of abuse may become a viable treatment option, there are several drawbacks that need to be considered. These include: a lack of protection against a structurally dissimilar drug that produces the same effects as the drug of choice;a lack of an effect on drug craving that predisposes an addict to relapse; and tremendous individual variability in antibody formation. Forced or coerced vaccination is not likely to work from a scientific perspective, and also carries serious legal and ethical concerns. All things considered, vaccination against a drug of abuse is likely to work best with individuals who are highly motivated to quit using drugs altogether and as part of a comprehensive treatment programme. As such, the medical treatment of drug abuse will not be radically

    Salinity cost agricultural sector over 27Bln pa in lost opportunities and is an issue that crosses all spatial and temporal scales - from individual fields, farms, catchments, landscapes to national and global levels. Salinity manifests itself in many forms and often leads to further soil degradation such as erosion, nutrient and soil organic matter depletion, and a loss of (soil) biodiversity. Salinity may also cause major disturbance to ecosystems due to its impact on resources (e.g. pollution of aquifers). In extreme cases it can turn previously highly productive areas into wastelands. An increasing global population and unprecedented urban sprawls are now putting additional pressures on our soil and water resources, particularly in regions where urbanisation directly competes with agriculture for access to land and water. And although everyone agrees that avoiding soil salinity in the first instance would be the most effective way of combating it, reality is that the amount of saline land and water resources is rapidly increasing, and will continue to increase, especially in developing countries. Purposefully designing our cropping systems that can cope with various levels of salinity could be one answer to this increasing problem. In this work we review some of the key cropping options that can be deployed to either avoid, reduce or remediate salt-affected lands. We argue that for these measures to be most effective an ongoing science - policy - society dialogue is required to ensure that policy frameworks that govern land and water management are conducive to reducing salinity or even assist in restoring affected areas. We first consider several case studies highlighting the extent of the problem using ongoing salinity hotspots around the globe. We then look at halophytes as a possible biological tools to remediate already saline sols, and discuss prospects of mixed (halophytes and glycophytes) cropping solutions for various agricultural systems at different

    1991-01-01

    NUMEROUS WORK TIME options have been developed to attract, retain and meet the various needs of nurses. Job sharing, a work option little known to nurses, can be a successful alternative for balancing professional and personal lifestyle. The business literature supports job sharing and other innovative work options as successful mechanisms in retaining quality employees in their respective professions. After exploring the literature in this area, a proposal for job sharing the oncology clinical nurse specialist (CNS) position was presented to the Personnel Director and Vice President of Nursing at our institution. The proposal addressed the advantages and disadvantages of the concept. These included: (1) scheduling flexibility, (2) reduced absenteeism and turnover, (3) increased productivity, (4) handling fringe benefits, and (5) job satisfaction. The proposal was accepted, and the job sharing position has been successfully implemented for more than 2 years now. This paper describes issues relevant to designing and implementing job sharing in a CNS position.

    In India, stroke care services are not well developed. There is a need to explore alternative options to tackle the rising burden of stroke. Telemedicine has been used by the Indian Space Research Organization (ISRO) to meet the needs of remote hospitals in India. The telemedicine network implemented by ISRO in 2001 presently stretches to around 100 hospitals all over the country, with 78 remote/rural/district health centers connected to 22 specialty hospitals in major cities, thus providing treatment to more than 25 000 patients, which includes stroke patients. Telemedicine is currently used in India for diagnosing stroke patients, subtyping stroke as ischemic or hemorrhagic, and treating accordingly. However, a dedicated telestroke system for providing acute stroke care is needed. Keeping in mind India's flourishing technology sector and leading communication networks, the hub-and-spoke model could work out really well in the upcoming years. Until then, simpler alternatives like smartphones, online data transfer, and new mobile applications like WhatsApp could be used. Telestroke facilities could increase the pool of patients eligible for thrombolysis. But this primary aim of telestroke can be achieved in India only if thrombolysis and imaging techniques are made available at all levels of health care. © 2014 World Stroke Organization.

    Full Text Available The management of terrestrial weed is of great concern for the scientific community as these weeds cause adverse effect in different ecosystems like forest, agriculture and urban. The widespread of these weeds by their adaptive capability and morphological advancement is difficult to control. Parthenium hysterophorous, Lantana camara, Saccharum spontaneum, Ageratum conyzoides are the weeds that spread all over the world. There are various management practices employed for the control of this weeds. But all of these practices have some drawbacks those are neither environment friendly nor economical. In this paper a review has been done to evaluate various alternative management practices for these terrestrial weeds and to analyze their feasibility. Vermicomposting and anaerobic digestion can be viable alternative option which is cost effective as well. There are few studies regarding vermicomposting and anaerobic digestions of terrestrial weeds are done.

    1995-01-01

    The National Research Council recently completed a three-year study entitled open-quotes Alternatives for Groundwater Cleanupclose quotes. One of the conclusions of this study indicated that for sites with a complex geologic and hydrologic set up, existing technologies may not be able to restore contaminated aquifers to health-based standards. Therefore, the most logical approach in these cases, perhaps, could be to adopt the open-quotes non-attainment zoneclose quotes policy. The essence of this policy is to first contain the plume and stop any further migration of contaminated groundwater, and then to remove the source of contamination. This paper briefly discusses some of the problems encountered with this approach for a contaminated area at the US Department of Energy's Lawrence Berkely National Laboratory

    2015-01-01

    Although bariatric surgery has become a recognized treatment for obesity, its utility among patients with severe psychiatric disorders has not been extensively studied. A few studies have reported similar weight loss outcomes in these patients, but psychiatric status after bariatric surgery has been studied only minimally, and it is unknown if exacerbation of the mental illness affects weight loss. The aim of this study was to shed greater light on the issue of serious mental illness and bariatric surgery. Specifically, do patients with a diagnosis of schizophrenia, bipolar I, and bipolar II have poorer weight loss outcomes postbariatric surgery than the general bariatric surgery population? Also, do patients with these diagnoses experience an exacerbation of psychiatric symptoms after bariatric surgery, and if so, is the exacerbation of these disorders linked to poorer weight loss results? Midwest university medical center. A medical record review of approximately 1500 bariatric patients in a Midwest university medical center was conducted to identify those patients with diagnoses of schizophrenia, bipolar I, and bipolar II. Information was gathered on bariatric surgery outcomes and changes in psychiatric status postsurgery. Eighteen patients were identified as undergoing bariatric surgery and having a diagnosis of schizophrenia, bipolar I, or bipolar II. Weight loss in this group was significant and comparable to expected outcomes of absolute weight lost, changes in body mass index, and percentage excess weight loss for patients in the typical bariatric population. Postsurgery psychiatric status was known on 10 patients. All 10 patients experienced some exacerbation of psychiatric problems yet weight loss outcomes were still as expected. Bariatric surgery is a viable obesity treatment option for patients with schizophrenia, bipolar I, and bipolar II disorders. Symptom exacerbations occurred postsurgery, although it is not clear if these were due to the surgery or

In this section, academics, policy makers and practitioners engage in a dialogue on global development challenges. Papers are copy-edited but not peer-reviewed. Instead, an initial thematic contribution is followed by critical comments and reactions from different stakeholders. This paper by Werner Thut is followed by reactions and analysis from a non-profit policy institute (Alexandra Gillies, Revenue Watch Institute, New York, ‘Crafting a Strategic Response to the Commodity-Development Conundrum’, a Southern scholar (Prof. Humberto Campodonico, Universidad Nacional Mayor de San Marcos, Lima ‘Going Beyond Transparency and Good Governance’ | ‘Más allá de la transparencia y una buena gobernanza’ and a representative of the trading sector (Stéphane Graber, Secretary General of Geneva Trading & Shipping Association – ‘Reassessing the Merchants’ Role in a Globalized Economy’.PAPER’S ABSTRACTSwitzerland is one of the world’s largest commodity trading hub. The author, senior policy adviser at the Swiss Agency for Development and Cooperation (SDC, reviews experiences and policy options related to commodity trading from a development policy perspective. While this sector has become of strategic importance to Switzerland’s economy, it also entails a number of risks. On the other hand, Swiss development cooperation efforts focus on several resource-rich countries, whose mineral and agricultural commodities are traded via Switzerland. How can Switzerland assist these countries to reap the benefits of their natural resource wealth? This paper looks at development policy aspects of commodity trading in relation to Swiss foreign and domestic policy. It examines ongoing policy debates in Switzerland and discusses development policy options.

    Rapid population growth is a threat to wellbeing in the poorest countries, whereas very low fertility increasingly threatens the future welfare of many developed countries. The mapping of global trends in population growth from 2005-10 shows four distinct patterns. Most of the poorest countries, especially in sub-Saharan Africa, are characterised by rapid growth of more than 2% per year. Moderate annual growth of 1-2% is concentrated in large countries, such as India and Indonesia, and across north Africa and western Latin America. Whereas most advanced-economy countries and large middle-income countries, such as China and Brazil, are characterised by low or no growth (0-1% per year), most of eastern Europe, Japan, and a few western European countries are characterised by population decline. Countries with rapid growth face adverse social, economic, and environmental pressures, whereas those with low or negative growth face rapid population ageing, unsustainable burdens on public pensions and health-care systems, and slow economic growth. Countries with rapid growth should consider the implementation of voluntary family planning programmes as their main policy option to reduce the high unmet need for contraception, unwanted pregnancies, and probirth reproductive norms. In countries with low or negative growth, policies to address ageing and very low fertility are still evolving. Further research into the potential effect of demographic policies on other social systems, social groups, and fertility decisions and trends is therefore recommended. Copyright © 2012 Elsevier Ltd.

    Mohan, Vinuta; Lind, Robert

    2016-01-01

    Graves' disease is the most common cause of hyperthyroidism. If left untreated, patients may have multiple systemic complications such as cardiac, reproductive, and skeletal disease. Thionamides, such as methimazole and propylthiouracil, and I(131) iodine ablation are the most commonly prescribed treatment for Graves' disease. Total thyroidectomy is often overlooked for treatment and is usually only offered if the other options have failed. In our case, we discuss a patient who was admitted to our medical center with symptomatic hyperthyroidism secondary to long-standing Graves' disease. She had a history of non-compliance with medications and medical clinic follow-up. The risks and benefits of total thyroidectomy were explained and she consented to surgery. A few months after the procedure, she was biochemically and clinically euthyroid on levothyroxine. She had no further emergency room visits or admissions for uncontrolled thyroid disease. Here we review the advantages and disadvantages of the more typically prescribed treatments, thionamides and I(131)iodine ablation. We also review the importance of shared decision making and the benefits of total thyroidectomy for the management of Graves' disease. Given the improvement in surgical techniques over the past decade and a significant reduction of complications, we suggest total thyroidectomy be recommended more often for patients with Graves' disease.

  3. Expanding policy options for educating teenagers.

    Stern, David

    2009-01-01

    David Stern argues that some basic features of the American high school must be modified if it is to serve all students successfully. He notes, for example, that only three-quarters of U.S. high school students graduate four years after beginning ninth grade and that the National Assessment of Educational Progress found no improvement in reading or mathematics for seventeen-year-olds between 1971 and 2004. The nation's system for educating teenagers, says Stern, seems to be stuck, despite the constant efforts of teachers and repeated waves of reform. Citing two widely accepted public purposes of educating teenagers-preparation for civic participation and for economic self-sufficiency-Stern proposes four new strategies to achieve those goals. He draws on empirical evidence suggesting that these are promising directions for research and policy, but acknowledges that existing studies provide only limited guidance. First, he says, schools should continue the current trend toward integrating educational options to provide young people with skills and experiences that pave the way to both college and careers. Second, states and districts should tie education funding not simply to the number of students attending school, but also to what young people learn, whether they graduate, and whether they find jobs or enroll in postsecondary education. Such a move, he argues, would encourage teaching and learning formats that use students' time more effectively. Third, more adults in addition to classroom teachers should be involved in educating teenagers. Other adults acting as academic advisers, learning coaches, student advocates, internship supervisors, mentors, and college counselors could help guide the education of teenagers inside and outside of school and provide some relief for the chronic shortage of teachers. Fourth, schools should expand the options for educating teenagers outside of geographically fixed schools. Combining improved Internet-based curriculum with

    Full Text Available In a market economy government resources are often insufficient to cover all the public budget needs. Public capital collecting process presents a particular interest considering the need of getting them with lower costs. The options for collecting public resources are characterized by diversity and complexity. One of them is based on municipal bonds funds. This paper explores the potential of public bonds issued at a local level in raising capital for infrastructure investments in Romanian public administration. This paper is not meant to be an empirical study at national level because sub-sovereign bonds market in Romania is not very developed. This paper is limited to a case study of public financing methods for a Romanian local public administration. Local authorities from Oradea have no other possibility without one of borrowing to achieve the objectives proposed. Thus, it resorted to a set of internal and external loans. Our study contents a comparative cost analysis of public financing by loans. The analysis lead to the result that the cheapest source of financing is the loan offered by the European Investment Bank, followed by municipal bonds issuing.

  6. GATS Mode 4 Negotiation and Policy Options

    2004-06-01

    Full Text Available This study reviews the characteristics and issues of GATS Mode 4 and guesses the effects of Mode 4 liberalization on Korean economy and labor market to suggest policy options to Korea. Mode 4 negotiation started from the trade perspective, however, since Mode 4 involves international labor migration, it also has migration perspective. Thus developed countries, that have competitiveness in service sector, are interested in free movement of skilled workers such as intra-company transferees and business visitors. On the other hand, developing countries, that have little competitiveness in service sector, are interested in free movement of low-skilled workers. Empirical studies predict that the benefits of Mode 4 liberalization will be focused on developed countries rather than developing countries. The latter may suffer from brain drain and reduction of labor supply. Nevertheless developed countries are reluctant to Mode 4 negotiation because they can utilize skilled workers from developing countries by use of their own temporary visa programs. They are interested in Mode 4 related with Mode 3 in order to ease direct investment and movement of natural persons to developing countries. Regardless of the direction of a single undertaking of Mode 4 negotiation, the net effects of Mode 4 liberalization on Korean economy and labor market may be negative. The Korean initial offer on Mode 4 is the same as the UR offer. Since Korean position on Mode 4 is most defensive, it is hard to expect that Korean position will be accepted as the single undertaking of Mode 4 negotiation. Thus Korea has to prepare strategic package measures to minimize the costs of Mode 4 liberalization and improve competitiveness of service sector.

    Outcomes of arthroscopic superior labral anterior-posterior (SLAP) repairs have been well reported with generally favorable outcomes. Unfortunately, a percentage of patients remain dissatisfied or suffer further injury after SLAP repair and may seek additional treatment. The purpose of this study was to evaluate the surgical outcomes of biceps tenodesis for failed SLAP repairs. A retrospective review of all patients undergoing biceps tenodesis was completed. Inclusion criteria were previous SLAP repair and subsequent revision biceps tenodesis. Exclusion criteria were additional shoulder procedures including rotator cuff repair, instability procedures, and preoperative frozen shoulder. Objective outcomes were postoperative assessments with Constant score, American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation, Simple Shoulder Test, and Veterans RAND 36-Item Health Survey. Physical examination was conducted to determine postoperative range of motion and strength compared with the nonoperative shoulder. A cohort of 24 patients was identified, and of these, 17 patients (71%) completed the study at 2 years' follow-up. The average postoperative Constant score was 84.4; American Shoulder and Elbow Surgeons score, 75.5; Single Assessment Numeric Evaluation score, 73.1%; Simple Shoulder Test score, 9.2; and Veterans RAND 36-Item Health Survey score, 76.1. Postoperative range of motion of the operative shoulder returned to near that of the asymptomatic nonoperative shoulder. Workers' compensation status led to inferior results. Options for patients with a failed prior SLAP repair are limited. As a salvage operation for failed SLAP repair, biceps tenodesis serves the majority of patients well, with favorable outcomes by validated measures and excellent shoulder range of motion and elbow strength at 2 years' follow-up. Workers' compensation status may predispose patients to poorer outcomes. Copyright © 2014 Journal of Shoulder and Elbow Surgery Board

  8. Freezing the biological clock: a viable fertility preservation option for young Singapore women?

    Blyth, Eric; Yee, Samantha; Lee, Geok Ling

    2013-09-01

    In March 2012, an article in The Straits Times entitled 'Freezing eggs could reverse falling birth rate' suggested that employing the latest oocyte cryopreservation techniques could both foster individual women's reproductive autonomy and impact Singapore's fertility rate, which in recent years has consistently been among the world's lowest. The article cited both local and international fertility specialists' approval of elective oocyte cryopreservation for young women wishing to protect their reproductive potential against ageing and as a potential antidote to the contemporary 'delay and defer' model of family-building. Later in 2012, the Ministry of Health announced a review of oocyte cryopreservation policy taking into account related medical, scientific and ethical issues, while the Singapore College of Obstetricians and Gynaecologists endorsed oocyte cryopreservation as an "important, safe and efficient technology". This paper outlines and analyses the arguments and empirical evidence used both to support and oppose offering elective oocyte cryopreservation as a routine fertility service, before concluding that this remains unjustifiable on the basis of insufficient evidence of its clinical efficacy and safety as regards either pregnancy rates or birth outcomes. If it is to be made available at all for these reasons in Singapore, it should be subjected to rigorous clinic-specific evaluation in accordance with accepted clinical and ethical norms.

    Estrogen replacement therapy is one of the most commonly prescribed medicines in the United States by traditional medical professionals. Over the past decade, the market for complementary/ alternative therapies for hormone replacement has dramatically increased. Women are seeking more "natural" alternatives to treat menopausal symptoms. Well-designed randomized clinical trials are often lacking, as is the information on efficacy and safety. This article will review several popular herbal therapies for menopausal symptoms including phytoestrogens, black cohosh (Cimicifuga racemosa), dong quai (Angelica sinensis), chast tree (Vitex agnus-castus), and wild Mexican yam. Their use, mechanism of action, and adverse effects are outlined.

    In the United States, fiscal and functional federalism strongly shape public health policy and programs. Federalism has implications for public health practice: it molds financing and disbursement options, including funding formulas, which affect allocations and program goals, and shapes how funding decisions are operationalized in a political context. This article explores how American federalism, both fiscal and functional, structures public health funding, policy, and program options, investigating the effects of intergovernmental transfers on public health finance and programs.

  13. Radiation indicator options for environmental policy

    2002-01-01

    It has proven impossible to create an indicator capable of showing the state of the art in a single figure so as to determine the progress made in the 'radiation component' of environmental policy from the trends indicated. This is the conclusion following an investigation requested by the Ministry of Housing, Spatial Planning and the Environment in the framework of the environmental theme 'dispersion of radioactive substances and ionising radiation' to develop a radiation indicator comparable to the indicators for proprietary substances and pesticides. The most important reasons for failing to develop this indicator lie in the absence of both suitable policy targets and data for the calculations necessary for the indicator. Substituting policy targets with reference emissions, reference concentrations and reference doses would make it possible to define indicators for radiation protection. Here, environmental pressure indicators are proposed for nuclear installations and the process industry. The environment...

    2007-07-01

    The paper analyzes the historical trends, resource distribution and forecasts the regional total primary energy consumption (TPEC) to 2050. The purpose is to provide a most probable path so that appropriate policies can be made to enhance/slowdown the energy consumption without hampering economic growth. Global TPEC is most likely to reach 763-1259 Quadrillion Btu (QBtu) to 2050 with reference case trending between and stood at 978 QBtu. By 2050 the equation of TPEC is expected to be tilted in favor of developing countries when their share is increased from 47 percent in 2003 to 59 percent. Asia developing region becomes the largest consumer of TPEC; however on per capita basis it remains the lowest after Africa. The forecast gives some guidance to policy makers. Which policy measures should be taken to ensure availability of predicted level of energy resources? How should we mobilize sizeable investment to increase the expected production/capacity/logistic both in the producing and consuming countries? Simultaneously, what strategic measures should be taken: to improve energy efficiency/conservation, development/promotion of renewable sources of energies and check population growth to downward shift the probable TPEC path without compromising economic growth, productivity and quality of life?

    Whether and in what way our society can cope with the risks of climate change and the challenge of sustainable development have been the subjects of the title project. In order to be able to answer such questions a dialogue was initiated within the project between scientists, policy makers and other societal actors, such as representatives of the trade unions, employer's organizations, ministries, businesses and environmental non-governmental organizations. In this way interest and risks of climate change were set side by side. In this brochure an overview is given of the results of the title project

    Bulatao, R A

    1984-11-01

    The 3rd Asian and Pacific Population Conference in Colombo in 1982 recommended that countries review and modify existing demographic targets and goals for reducing birth and death rates in order to attain low levels as early as possible and to attain replacement level by the year 2000. The demographic goals of selected Asian countries (Bangladesh, Indonesia, Korea, Thailand, India, Pakistan, and the Philippines are assessed and compared to World Bank population projections. It also discusses the underlying rationale for setting fertility targets, and considers what government actions could make them more achievable. 6 stages for controlling population are distinguished: 1) collection and publication of reliable demographic data; 2) enunciation of an official policy to reduce population growth; 3) development of appropriate institutions to integrate demographic projections into economic plans; 4) promotion of family planning; 5) provision of incentives and disincentives, including elimination of all implicit and explicit subsidies for child bearing; and 6) restitution of birth quotas requiring permission for each child born. Principles to maintain and accelerate fertility declines to meet demographic targets include creating appropriate and equitable development policies, increasing the standard of family planning programs, confronting organizational problems, providing easier and more equal access to contraceptive methods, exploring innovative approaches to encourage smaller families and making a firm political commitment to population control. Rapid fertility decline will also require financial commitment. Willingness to spend the necessary amounts, and the capacity to spend them as well, will determine whether the countries of Asia enter the next century in control of their population.

  2. Policy Options for Reducing Dietary Sodium Intake

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Faced with soaring health-care costs, Canadian governments should consider creative ways to enable the population to stay healthy — and making it possible for Canadians to reduce their sodium intake is an extremely cost-effective way to do so. Excess sodium consumption is a risk factor for high blood pressure, stroke and heart disease. On average, Canadians consume 3,400 mg of sodium a day (1,100 mg over recommended levels, at least three-quarters of which comes from processed foods. Any attempt at sodium reduction must therefore involve the food industry. This paper surveys sodium reduction efforts in jurisdictions around the globe, as well as past Canadian attempts, to provide provincial and federal policymakers with a comprehensive suite of lessons learned and a host of far-sighted policy recommendations ranging from food procurement to legislation and private sector engagement. Provincial governments, individually or together, must launch multi-pronged efforts involving food service companies, manufacturers, post-secondary institutes and the media to ensure that low-sodium alternatives are readily available, and that consumers are aware of them. They must also support federal action on changing dietary guidelines and introducing restrictions on food advertising to children. The benefits to be had are very real. In light of evidence showing that population-level intervention is superior to clinical intervention in terms of cost-effectiveness, returning up to $11.10 for every dollar spent and generating tens of billions in direct health-care savings, there is a very strong case for investing in population-level sodium reduction interventions that will work. The time for governments to act is now.

  3. Cost effectiveness of GHG mitigation options and policy implication

    1998-04-01

    This paper represents the summary findings and conclusions of several studies implemented about microeconomics and macroeconomics marginal costs of GHG abatement policies. Financial, economic, and, where possible, environmental microeconomics costs of reducing GHGs are estimated by a World Bank team. Six energy-related CO{sub 2} mitigation policy options are applied to estimate the macroeconomics costs of GHG emission reduction, the macroeconomics impacts on the Chinese economy. In terms of policy, conservation is a better option to cope with a restrictive mitigation constraint, assuming a developing country can achieve planned energy-saving targets. Without a CO{sub 2} emission constraint or with less restrictive CO{sub 2} emission constraints, however, the simulation results indicate that a conservation strategy may be less attractive than fuel substitution in a developing country, mainly due to the economic dampening effect of reduced production in the energy sectors. This finding suggests that an often-cited costless or negative-cost energy conservation policy may not be a better option when a less restrictive mitigation target is in force. This does not mean that the potential for energy efficiency improvements in a developing country is not worthwhile, but that the overall macroeconomics impacts should be considered before implementing the policy option.

    2017-01-01

    Using microsimulation, we estimate the effects of three policy proposals that would alter Social Security's eligibility rules or benefit structure to reflect changes in women's labor force activity, marital patterns, and differential mortality among the aged. First, we estimate a set of options related to the duration of marriage required to receive divorced spouse and survivor benefits. Second, we estimate the effects of an earnings sharing proposal with survivor benefits, in which benefits are based entirely on earned benefits with spouses sharing their earnings during years of marriage. Third, we estimate the effects of adjusting benefits to reflect the increasing differential life expectancy by lifetime earnings. The results advance our understanding of the distributional effects of these alternative policy options on projected benefits and retirement income, including poverty and supplemental poverty status, of divorced and widowed women aged 60 or older in 2030.

    Climate change and fossil fuel depletion are the main drivers for the recent focus on Renewable Energy (RE) resources. However, since the high cost of RE technologies is the main obstacle facing the diffusion of RE power generation, economic and political intervention is inevitable. In the United Arab Emirates (UAE) population and economic growth are the main causes of a sharp increase of energy demand. Two key related factors highlight the need to establish a RE sector: first the UAE has one of the highest carbon footprint in the world and second, the rate of depletion of its main energy generation resource – fossil fuel. In this study, we present a review of overall policies in sixty-one countries, focusing on their efforts to adopt RE resources in the power sector, and on their implementation of fundamental policies implemented. Furthermore, we investigate the applicability to Abu Dhabi UAE of the main RE policies implemented worldwide. As a result of our analysis, we recommend the implementation of a mixed policy of Feed-in-Tariff (FIT) and the Quota system for RE electricity generation in order for the UAE to meet its 7% target by 2020. - Highlights: ► Comprehensive review of renewable energy policy mechanisms. ► Summarizes the renewable energy policy adoptions, targets, and installed capacity in many countries. ► Gives recommendations on renewable energy policy options for Abu Dhabi, an oil rich country.

    Newton, J.

    2001-01-01

    This paper presents an initial compilation of background material in support of the development of climate change policy options for the jurisdictions of Yukon, Northwest Territories and Nunavut in Northern Canada. While Northern Canada contributes only a small fraction of the world's greenhouse gas (GHG) emissions, scientists forecast changes in average annual temperatures to be among the highest in the world. The Northern Climate Exchange at Yukon College was created in March 2001 to address this issue and to help guide northerners in what they can do now and in the future. This paper includes an annotated bibliography of a total of 75 international, national, and territorial policy documents and major reference documents relevant to climate change issues. It is meant to be a resource for researchers, policy analysts and government officials developing policy options and implementing programs for Northern Canada. While each of the three northern territories are at a different stage in the evolution of their climate change activities, they are all striving to develop strategies and action plans and to initiate the implementation of those plans. It is recognized that many long-standing programs and initiatives, particularly in the areas of energy efficiency and alternate energy, will help northern jurisdictions address their climate change objectives. The three territories are cooperating to deliver their message to the federal government. 75 refs., 4 figs

    shift in investment strategy than the lure of better profits. However strong the evidence of an imminent peaking of offshore and perhaps total non-OPEC oil supply, the reality is that governments will not readily recognise a 'bad news' scenario that will inevitably tarnish their own political image. It follows that a global and permanent threat to their economies and energy security from a shortfall in oil supply outside the Persian Gulf and central Asia will only become a policy assumption if viable and attractive energy policy options are available. If there is single focus to any energy supply threat, then it is the market for transportation fuels, the strongest growing segment of the energy market and the only segment of the energy market where there are no significant alternatives already on offer. The second half of this paper suggests that there are industrial or financial obstacles to the large-scale introduction of fuels other than current specification gasoline and diesel. Almost all the current initiatives to explore and encourage alternative fuels address a long-term future in which fuel cells or hydrogen or 'California-clean' liquids replace the current fuels at the pump. Further, most research concentrates on the environmental aspects of the alternatives rather than their large-scale industrial availability. Yet the hard reality is that any solution to the global oil supply dilemma must be large scale (at least 10% of the total market for transportation fuels) and soon, which means within a decade. The technical facts are that fuels such as ethanol and methanol can be produced in very large volumes and delivered to the consumer without any significant change to the huge infrastructure constituted by the global internal combustion engine manufacturing industry and by the existing fuel distribution networks. This large, immediate and obvious opportunity has not been grasped so far for the excellent reason that the status quo is profitable

    In Iran, based on the recent national policy documents, physician dual practice (PDP) has been prohibited. This study aimed to develop policy options (POs) to implement physicians' dual practice prohibition law in Iran. International evidence published in English and local documents published in Persian about PDP analyzed and results (advantages, disadvantages, challenges and requirements to ban PDP, and applied policies to limit the dual practice) were extracted. Results discussed among the research team in 5 rounds of meetings. In each meeting, any possible PO to limit PDP in Iran was proposed based on brainstorming technique and 12 POs were developed. These 12 POs and their advantages and disadvantages were discussed in a focus group discussion attended by 14 informed policy makers, and 3 additional POs were added. Fifteen POs were developed. Each PO has its own advantages and disadvantages. It is worth to highlight that not only are the proposed POs not mutually exclusive but they are also mutually reinforcing; that is, each of these POs can be applied alone or they can be implemented alongside each other simultaneously. No single optimal PO exists for dealing with the dual practice in Iranian health system. Implementing a mix of POs could reduce possible complications of each PO and increase the chance of successful implementation of the law. It is advisable to follow a conservative and incremental approach and start with POs that will cause less resistance and political challenges. Copyright © 2018 John Wiley & Sons, Ltd.

    The seriousness of the potential impacts of climate change on development in Africa is now well recognized within, and increasingly outside, scientific circles. The United Nations Framework Convention on Climate Change is a landmark in international environmental governance, providing a mechanism for exchange, negotiation and institution-building to re-direct development towards more efficient use of resources, especially energy. The message of 'A climate for Development' is that unless policy-makers fully understand both the international commitments made under the Convention and the essential national development priorities of their own countries, effective action on climate change is unlikely to be realized. The action needed, however, can at the same time stimulate capacity-building, planning and policy change which would strengthen the economic and ecological base of African countries. The climate change issue has hence brought us face to face with the urgency of the basic issues of sustainable development in Africa. The book discusses key issues that cut across all African countries, such as emissions and their impacts, financial resources and technology transfer for emissions abatement strategies. It then provides a sectoral analysis of greenhouse gas emissions and abatement options focusing on energy, industry, agriculture, forestry and transportation. The book concludes with guidelines for options which may be considered by African countries to ensure that climate change concerns are effectively dealt with in the context of their development priorities. 113 refs

    2013-05-15

    In 2009, the EU climate and energy package with targets for 2020 (the so-called 20-20-20 targets) were formulated. For the period after 2020, however, there are no legally binding targets at the EU level, except for a decreasing ETS cap which will not be sufficient in light of the ambition for 2050. This leads to uncertainty for market players, as project lead times are long and high upfront investments need to deliver returns well beyond 2020. In its Green Paper on a 2030 framework for climate and energy policies, the European Commission recognised the need for clarity regarding the post-2020 policy framework. Currently under discussion is whether the approach for 2020 should be continued towards 2030 in the form of three more stringent targets or that other approaches would be more appropriate. Within this context, the Dutch Government asked PBL Netherlands Environmental Assessment Agency and Ecofys for advice. PBL and Ecofys have subsequently analysed possible options for an EU policy framework for 2030 that will steer towards a low-carbon economy by 2050 in a cost-effective way.

  15. Developing a global health diplomacy supply chain--a viable option for the United States to curb extremism.

    Kumar, Sameer; Honkanen, Erik J; Karl, Chad C

    2009-01-01

    This study examines the idea of developing a global health diplomacy supply chain as an important foreign policy approach with the aim of improving the lives of vulnerable populations and serving the best interests of the United States. The study was based on the review of academic literature, news events, and military communiques, and historical writings were studied to determine the feasibility of the idea and the extent of costs and benefits of such an endeavor. An integrated strategic business model, supported by a medical care delivery process, was developed to create a framework for a feasible global health diplomacy supply chain. The findings indicate that extremism can be contained by creating and efficiently executing an effective supply chain to get medical care units to those that need them. The limitations are the potential exit strategies required, the tactical abilities, and diplomatic techniques needed in order to create positive diplomatic change in aid distribution. Managers must consider how supply chains will affect other organizations giving aid and the potential public response. Moreover, determining the level of care necessary to achieve the greatest positive health diplomacy continues to require vigilant scrutiny over the potential cost/benefit analysis. The analysis is valuable to policymakers considering the impacts of health diplomacy by utilizing supply chain management.

    Insight is given into the local policy options with respect to climate change, in this case within the sphere of influence of Amsterdam local authorities. A list of new policy options for CO2-reduction has been made with the assistance of local policy makers and representatives of interest groups. These policy options have been divided into three qualitative scenarios: Institutional Cultural Change, Technological Innovation and Least Regrets. The environmental, economic and other effects have been described for each policy option. The three most interesting policy options have been selected by local policy makers and representatives of interest groups during a workshop. Implementation strategies have been developed for the options selected. These strategies have been discussed during a second workshop. The reduction target, stabilization of CO2-emissions in 2015 compared to 1993, can be realized by a combination of all the new policy options. The three selected policy options count for 40% of this total CO2-emission reduction. Finally, a general outline on the methodology to construct local policies for climate protection has been described. This methodology can also be applied to other cities and municipal administrators, e.g. participants of Cities for Climate Protection, an initiative of the International Council for Local Environmental Initiatives, or the Netherlands Climate Association. 136 refs

    prices. Furthermore, land use change both through converting natural land to produce 1st generation biofuels, and by displacing existing agricultural activities to other areas, may drastically impact the greenhouse gas (GHG) emission reduction of biofuels production and use. However, there are ways to reduce negative impacts. Even though shifting to second generation (2nd generation) biofuels appears to be one of the best solutions in terms of decreasing the pressure on agricultural commodity markets and improving GHG performances of biofuels, a mix of 1st and 2nd generation biofuels will be the likely future. In this respect, strategies to increase agricultural productivity, especially in developing countries where yields presently are low, stands out as one of the most important requirements. Food security and agricultural productivity improvements have been addressed as part of the millennium development goals (MDG's). But policy-driven biofuel production that impacts global agricultural markets should also become part of the policy framework that supports agricultural productivity increase in the world regions that are likely to be impacted most with increased biofuel demand. 2nd generation biofuels can decrease some of the pressure on agriculture commodities if they are produced from residues and crops cultivated on marginal lands. They are in addition expected to provide a substantial contribution to reducing GHG emissions. However, those technologies are still at demonstration stage and bringing them to the market requires policy measures that take into account their risk profiles and create a favourable and stable investment climate. A set of policy options, for instance combinations of high investment subsidies with soft loans, tax exemptions, and favourable crediting in relation to biofuel targets, can help overcome the initial investment barriers and enable larger volumes of 2nd generation biofuel penetration into the market.

    Biomass, one of the most important renewable energies, is playing and will continue to play an important role in the future energy structure of the world. This article aims to analyze the position and role, assess the resource availability, discuss the geographic distribution, market scale and industry development, and present the policy options of biomass in China. The resource availability and geographical distribution of biomass byproducts are assessed in terms of crop residues, manure, forest and wood biomass byproducts, municipal waste and wastewater. The position of biomass use for power generation is just next to hydropower among types of renewable energy in China. The potential quantity of all biomass byproducts energy in 2004 is 3511 Mtce (Mtce is the abbreviation of million tons of coal equivalents and 1 Mtce is equal to106 tce.), while the acquirable quantity is 460 Mtce. Biomass energy plays a critical role in rural regions of China. The geographical distribution and quantity of biomass byproducts resources depends mainly on the relationship between ecological zones and climate conditions. Our estimation shows that the total quantity of crop residues, manure, forest and wood biomass byproducts, municipal waste and wastewater resources are 728, 3926, 2175, 155 and 48240 Mt (million tons), respectively. Crop residues come mainly from the provinces of Henan, Shandong, Heilongjiang, Jilin and Sichuan. All manure is mainly located in the provinces of Henan, Shandong, Sichuan, Hebei and Hunan. Forest and wood biomass byproducts are mainly produced in the provinces or autonomous regions of Tibet, Sichuan, Yunnan, Heilongjiang and Inner Mongolia, while most of municipal waste mainly comes from Guangdong, Shandong, Heilongjiang, Hubei and Jiangsu. Most of wastewater is largely discharged from advanced provinces like Guangdong, Jiangsu, Zhejiang, Shandong and Henan. Biomass byproducts’ energy distribution also varies from province to province in China. Based on

    The problem of site allocation on locally unwanted land uses related to energy utilities that extended most recently is becoming a new energy policy issue due to the improvement of national standard of living and livelihood quality. Residents do not generally agree on establishing the construction of public energy utilities in their village due to NIMBY syndrome while they basically agree to have them. These circumstances made a big problem against mass production of industry society and the improvement of the national welfare. Locally unwanted land use related to energy utilities includes waste incineration system, nuclear power plant, coal fired power plant, oil and Gas storage tank, briquette manufacturing plant and etc. Opportunity for SOC projects carried out by central and local government is lost because of the regional egoism. The site dispute between government and residents obstructs optimal energy supply to be necessary for industry growth and the national welfare. The main objective of this study is to propose the policy option for finding a solution after surveying theory and background of site troubles and dispute factors. Final results of this study propose a solution on structural and institutional dispute. The former introduces three kinds of approaches such as tradition, compensation and negotiation. The transition of an environmentally sound energy consumption pattern and the improvement of energy efficiency could be carried out by traditional approaches. To claim the damage and offer the accommodation facilities could be settled by compensational approaches. The establishment of regional decentralization on NIMBY facilities could be settled by negotiatory approaches through fair share criteria. The latter proposes 1) 'polluter pays principle', 2) internalization of social cost and benefit on air or water pollution, 3) the behind - the - scene negotiation in a bid to settle a site dispute, 4) and supporting system for peripheral areas

  1. A Policy Alternative Analysis and Simplified Scoring Method to Assess Policy Options for Marine Conservation Areas

    Traditional approaches to marine conservation and management are increasingly being found as inadequate; and, consequently, more complex ecosystem-based approaches to protecting marine ecosystems are growing in popularity. Ecosystem-based approaches, however, can be particularly challenging at a local level where resources and knowledge of specific marine conservation components may be limited. Marine conservation areas are known by a variety of names globally, but can be divided into four general types: Marine Protected Areas (MPAs), Marine Reserves, Fishery Reserves, and Ecological Reserves (i.e. "no take zones"). Each type of conservation area involves specific objectives, program elements and likely socioeconomic consequences. As an aid to community stakeholders and decision makers considering establishment of a marine conservation area, a simple method to compare and score the objectives and attributes of these four approaches is presented. A range of evaluation criteria are considered, including conservation of biodiversity and habitat, effective fishery management, overall cost-effectiveness, fairness to current users, enhancement of recreational activities, fairness to taxpayers, and conservation of genetic diversity. Environmental and socioeconomic costs and benefits of each type of conservation area are also considered. When exploring options for managing the marine environment, particular resource conservation needs must be evaluated individually on a case-by-case basis and the type of conservation area established must be tailored accordingly. However, MPAs are often more successful than other conservation areas because they offer a compromise between the needs of society and the environment, and therefore represent a viable option for ecosystem-based management.

    2006-01-01

    OECD/NEA has performed a study on the impact of advanced fuel cycle options on waste management policies with 33 experts from 12 member countries, 1 non-member country and 2 international organizations. The study extends a series of previous ones on partitioning and transmutation (P and T) issues, focusing on the performance assessments for repositories of high-level waste (HLW) arising from advanced fuel cycles. This study covers a broader spectrum than previous studies, from present industrial practice to fully closed cycles via partially closed cycles (in terms of transuranic elements); 9 fuel cycle schemes and 4 variants. Elements of fuel cycles are considered primarily as sources of waste, the internal mass flows of each scheme being kept for the sake of mass conservation. The compositions, activities and heat loads of all waste flows are also tracked. Their impact is finally assessed on the waste repository concepts. The study result confirms the findings from the previous NEA studies on P and T on maximal reduction of the waste source term and maximal use of uranium resources. In advanced fuel cycle schemes the activity of the waste is reduced by burning first plutonium and then minor actinides and also the uranium consumption is reduced, as the fraction of fast reactors in the park is increased to 100%. The result of the repository performance assessments, analysing the effect of different HLW isotopic composition on repository performance and on repository capacity, shows that the maximum dose released to biosphere at any time in normal conditions remains, for all schemes and for all the repository concepts examined, well below accepted radiation protection thresholds. The major impact is on the detailed concept of the repositories, through heat load and waste volume. Advanced fuel cycles could allow a repository to cover waste produced from 5 to 20 times more electricity generation than PWR once-through cycle. Given the flexibility of the advanced fuel

  4. A real option-based model to valuate CDM projects under uncertain energy policies for emission trading

    Highlights: • A real option-based model for the valuation of CDM projects is proposed. • This study investigates the impact of energy policies on the value of CDM projects. • Level of target emission and its schedule should be carefully designed. • Government subsidy facilitates the implementation of CDM projects. • Period for free emission allowance prevents promoting CDM projects. - Abstract: Emission trading has been considered a primary policy tool for emission reduction. Governments establish national targets for emission reduction and assign emission reduction goals to private entities to accomplish the targets. To attain the goal, private entities should perform offset projects that can produce emission credits or buy emission credits from the market. However, it is not easy for private entities to decide to implement the projects because energy policies associated with emission trading keep changing; thus, the future benefits of the offset projects are quite uncertain. This study presents a real option-based model to investigate how uncertain energy policies affect the financial viability of an offset project. A case study showed that the establishment of a target emission was attractive to the government because it could make the CDM project financially viable with a small amount of government subsidy. In addition, the level of the government subsidy could determine the investment timing for the CDM project. In this context, governments should be cautious in designing energy policies, because even the same energy policies could have different impacts on private entities. Overall, this study is expected to assist private entities in establishing proper investment strategies for CDM projects under uncertain energy policies

    - In some instances the standard method of doing molecular testing from formalin-fixed, paraffin-embedded block is not possible because of limited tissue. Tumor cell-enriched cell-transfer technique has been proven useful for performing immunocytochemistry and molecular testing on cytologic smears. - To establish the cell-transfer technique as a viable option for isolating tumor cells from hematoxylin-eosin (H&E)-stained slides. - Molecular testing was performed by using the cell-transfer technique on 97 archived H&E-stained slides from a variety of different tumors. Results were compared to the conventional method of molecular testing. - Polymerase chain reaction-based molecular testing via the cell-transfer technique was successfully performed on 82 of 97 samples (85%). This included 39 of 47 cases for EGFR, 10 of 11 cases for BRAF, and 33 of 39 cases for KRAS mutations. Eighty-one of 82 cell-transfer technique samples (99%) showed agreement with previous standard method results, including 4 mutations and 35 wild-type alleles for EGFR, 4 mutations and 6 wild-type alleles for BRAF, and 11 mutations and 21 wild-type alleles for KRAS. There was only 1 discrepancy: a cell-transfer technique with a false-negative >KRAS result (wild type versus G12C). - Molecular testing performed on H&E-stained sections via cell-transfer technique is useful when tissue from cell blocks and small surgical biopsy samples is exhausted and the only available material for testing is on H&E-stained slides.

    Since a decision-making by intuitive judgement under uncertain future conditions can not select an optimum alternative, reaching an agreement for alternatives between experts requires a development of several scientific opinion collection methodologies and performing these methodologies. Therefore, opinion collection for all points related to the nuclear energy, public hearing induction related researches and the acts, procedure, etc. performed in developed countries such as U.S, U.K, France, etc. are reviewed and analyzed in this research. And after the analysis of domestic spent nuclear fuel management plan, Task Force Team composed of experts in several related areas is organized to suggest strategies and directions which are necessary for making a national policy. Beside, Task Force Team selects an optimum technical alternative by the analysis and comparison in depth between these technical alternatives to establish the policy direction. They also established the procedures such as opinion collecting, etc. through policy conference and forum and suggested the technical data related nuclear policy which supports the nuclear policy conference. Results from this research are expected to decrease the trial and error that has been occurred in the present policy-making procedure such as radioactive waste repository related procedure and contribute for socio-cultural stability. Moreover, opinion collection plan for developing a nuclear policy alternative is expected to contribute for making a nuclear policy in the nuclear policy conference so that the nuclear technology will be enhanced more.

    Full Text Available Studies on the priorities for agricultural research in Eastern and CentralAfrica concluded that milk is the most important commodity for research anddevelopment in the region, based on its potential contribution to the agriculturalGDP. It has been presumed that, the right policies, marketing systems and technicalsupport must be sought for dairy development in Africa. In order to determine theright development pattern, appropriate analytical tools must be applied. The TIPICAL(Technology Impact Policy Impact model was used to analyse the impact ofdifferent policies on two typical dairy farming systems in Uganda, which accountfor more than 70% of milk produced in the country. Seven influential policy areaswere also identified: provision of veterinary services, consumption promotion,marketing promotion, input provision, credit access improvement, milk qualityimprovement and genetic improvement. In general, the policy impacts are very littleon farms with local cows but can be magnified up to threefold, if the farms havegraded cows. Policies which improve farmers’ accessibility to markets have thegreatest impacts. The results obtained from this model were compared to thoseusing the EXTRAPOLATE model. This comparison shows that both models couldcomplement each other in analysing policy impacts on African dairy farms.However, differences in results from the models indicate that more focus should bemade on farmers’ willingness to adopt new technology.

  17. Renewable energy policy evaluation using real option model. The case of Taiwan

    International Nuclear Information System (INIS)

    Lee, Shun-Chung; Shih, Li-Hsing

    2010-01-01

    This study presents a policy benefit evaluation model that integrates cost efficiency curve information on renewable power generation technologies into real options analysis (ROA) methods. The proposed model evaluates quantitatively the policy value provided by developing renewable energy (RE) in the face of uncertain fossil fuel prices and RE policy-related factors. The economic intuition underlying the policy-making process is elucidated, while empirical analysis illustrates the option value embedded in the current development policy in Taiwan for wind power. In addition to revealing the benefits that RE development provides when considering real options, analytical results indicate that ROA is a highly effective means of quantifying how policy planning uncertainty including managerial flexibility influences RE development. In addition to assessing the policy value of current RE development policy, this study also compares policy values in terms of internalized external costs and varying feed-in tariff (FIT). Simulation results demonstrate that the RE development policy with internalized CO 2 emission costs is appropriate policy planning from sustainability point of view. Furthermore, relationship between varying FIT and policy values can be shown quantitatively and appropriate FIT level could be determined accordingly. (author)

  18. Payout phase in DC pension funds – policy option - Theoretical considerations and Albanian available options

    2015-11-01

    Full Text Available The aim of this paper is to provide a brief overview of the third pillar of pensions in Albania and what are the different alternatives related to the payout. Referring to the actual development of this market in Albania, experience of the actors involved, I find it indispensable and necessary to provide some theoretical background and considerations, and then build up a simple model of projection of a pension scheme cost and a model for payout alternatives for the Albanian pension funds. A great deal of importance is shown towards posing the assumptions. Also, the paper gives an explanation about the differences among different payout options and suggests the best option for the existing pension funds in Albania. The best option represents my conclusion and recommendation for the actual third pillar of pensions and the others that might join latter. To sum up, the first conclusion of the paper is that the annuity option is the best alternative for the payout phase of the pensions. It has the advantage of providing the highest protection against the risk of longevity. The second conclusion is that based on other countries experiences, the annuity market have to be developed hand in hand with the pension system development. Therefore Albania should rely on and follow this experience.

  19. Incentive Policy Options for Product Remanufacturing: Subsidizing Donations or Resales?

    2017-01-01

    Remanufactured products offer better environmental benefits, and governments encourage manufacturers to remanufacture through various subsidy policies. This practice has shown that, in addition to product sales, remanufactured product can also achieve its value through social donation. Based on the remanufactured product value realization approaches, governments provide two kinds of incentive policies, which are remanufactured product sales subsidies and remanufactured product donation subsidies. This paper constructs a two-stage Stackelberg game model including a government and a manufacturer under two different policies, which can be solved by backward induction. By comparing the optimal decision of the two policies, our results show that, compared with the remanufacturing sales subsidy, donation subsidy weakens the cannibalization of remanufactured products for new products and increases the quantity of new products. It reduces the sales quantity of remanufactured products, but increases their total quantity. Under certain conditions of low subsidy, the manufacturer adopting sales subsidy provides better economic and environmental benefits. Under certain conditions of high subsidy, the manufacturer adopting donation subsidy offers better economic and environmental benefits. When untreated product environmental impact is large enough, donation subsidy policy has a better social welfare. Otherwise, the choice of social welfare of these two different policies depends on the social impact of remanufactured product donated. PMID:29194411

    A comprehensive case study was conducted on the policy problem of disposing of US weapons-grade plutonium, which has been declared surplus to strategic defense needs. Specifically, implementation of the mixed-oxide fuel disposition option was examined in the context of national and international nonproliferation policy, and in contrast to US plutonium policy. The study reveals numerous difficulties in achieving effective implementation of the mixed-oxide fuel option including unresolved licensing and regulatory issues, technological uncertainties, public opposition, potentially conflicting federal policies, and the need for international assurances of reciprocal plutonium disposition activities. It is believed that these difficulties can be resolved in time so that the implementation of the mixed-oxide fuel option can eventually be effective in accomplishing its policy objective.

  3. Multiperiod Production and Ordering Policies for a Retailer-Led Supply Chain through Option Contracts

    2018-01-01

    Full Text Available This paper formulates two groups of multiperiod production and ordering models with call and bidirectional option contracts for a two-party supply chain consisting of one followed supplier and one dominant retailer, respectively. Based on dynamic programming theory, we characterize the optimal policy structures for two partners in each period. We also provide an approximation for the corresponding policy parameters evaluation in two cases. Then, we investigate the impacts of different option contracts and the demand risk on the decisions and performances of two members. Our results suggest that, whether concerning call or bidirectional option contracts, the optimal policies for two members always follow a base stock type. When the price parameters are the same for different option contracts, the service levels of both the system and the retailer are higher with call option contracts than with bidirectional ones, whereas the retailer’s inventory risk is lower with bidirectional option contracts than with call ones. Under the same conditions stated above, call option contracts can always benefit the supplier, but not the retailer. Owing to the retailer’s dominant position, call option contracts are better choice for the supply chain if the option (exercise price is low (high, while bidirectional option contracts are more suitable choice for the supply chain if the option (exercise price is high (low. In addition, an increase in the demand risk would prompt the supplier to increase his production quantity and the retailer to reduce the initial firm order quantity, either with call or bidirectional option contracts.

A cost benefit analysis of two cannabis policy options the status quo (where cannabis use is illegal and a legalised-regulated option was conducted. METHOD: A cost benefit analysis was used to value the costs and benefits of the two policies in monetary terms. Costs and benefits of each policy option were classified into five categories (direct intervention costs, costs or cost savings to other agencies, benefits or lost benefits to the individual or the family, other impacts on third parties, and adverse or spill over events. The results are expressed as a net social benefit (NSB. FINDINGS: The mean NSB per annum from Monte Carlo simulations (with the 5 and 95 percentiles for the status quo was $294.6 million AUD ($201.1 to $392.7 million not substantially different from the $234.2 million AUD ($136.4 to $331.1 million for the legalised-regulated model which excludes government revenue as a benefit. When government revenue is included, the NSB for legalised-regulated is higher than for status quo. Sensitivity analyses demonstrate the significant impact of educational attainment and wellbeing as drivers for the NSB result. CONCLUSION: Examining the percentiles around the two policy options, there appears to be no difference between the NSB for these two policy options. Economic analyses are essential for good public policy, providing information about the extent to which one policy is substantially economically favourable over another. In cannabis policy, for these two options this does not appear to be the case.

  13. Renewable energy policy in South Africa: policy options for renewable electricity

    International Nuclear Information System (INIS)

    Winkler, H.

    2005-01-01

    Investment in renewable energy and energy efficiency is important to reduce the negative economic, social and environmental impacts of energy production and consumption in South Africa. Currently, renewable energy contributes relatively little to primary energy and even less to the consumption of commercial energy. This article examines policy options for promoting renewable electricity. Feed-in tariffs guarantee prices for developers, but lack certainty on the amount of renewable electricity such laws would deliver under local conditions.

    Investment in renewable energy and energy efficiency is important to reduce the negative economic, social and environmental impacts of energy production and consumption in South Africa. Currently, renewable energy contributes relatively little to primary energy and even less to the consumption of commercial energy. This article examines policy options for promoting renewable electricity. Feed-in tariffs guarantee prices for developers, but lack certainty on the amount of renewable electricity such laws would deliver under local conditions. Portfolio standards set a fixed quantity, which would guarantee diversity of supply. The question is whether the incremental upfront cost to be paid by society may be unacceptably high, compared to future health and environmental benefits. A renewables obligation combines the setting of a target with a tendering process, but may be bureaucratic to administer. Neither setting targets or regulating prices alone, however, will be sufficient. Power purchase agreements, access to the grid and creating markets for green electricity are some supporting activities that should be considered. Given that renewable electricity technologies have to compete with relatively low electricity tariffs, funding will be needed. Possible sources, both locally and internationally, are identified. The extent to which these are utilised will determine the future mix of renewable energy in South Africa

    Full Text Available Economic system after 1990 had many fluctuations. This article applies to two essential phenomena in a free market economy: inflation and unemployment. This article applies to changes in the process of inflation and fluctuations in the unemployment rate under different economic policy options. Economic policies can affect the development of the inflation and unemployment. It includes interest rates and budget deficits. Methodology of model is based on a pendulum. Economic policy has been designated as a synthetic indicator of the resultant two policies - monetary and fiscal policies. With the help of the pendulum model has been established that the character had run monetary and fiscal policy, and how developed as economic policy. By the dominance of one of the policy options is understood that during cycles level inflation or the deficit fluctuated strongly to economic stabilization. One of the stages of the study was to analyze the monetary policy and assess whether there is a link between the evolution of interest rates and the evolution of the inflation rate. In a similar way, fiscal policy was analyzed. This article attempts to determine whether the conduct of economic policy was correct, and has had an impact on the economic situation.

    By 2002, China's prevalence of overweight and obesity among adults was 18.9 and 2.9%, respectively. The replacement of traditional Chinese diet with 'Western diet', major declines in all phases of activity and increased sedentary activity are cited as the main reasons explaining the rapid increase in overweight and obesity, which bring major economic and health costs. The Nutrition Improvement Work Management Approach was released in 2010. Overweight and obesity prevention-related policies were added to national planning for disease prevention and control. The Guidelines for Prevention and Control of Overweight and Obesity of Chinese Adults and the School-age Children and Teenagers Overweight and Obesity Prevention and Control Guidelines in China were promulgated in 2003 and 2007, respectively. Few education programmes have been implemented. Selected academic intervention research projects dominate with a focus on reducing child obesity and promoting healthier diets; increasing physical activity and reducing sedentary time; and facilitating changes in family, school, social and cultural environments. Intervention samples are small and have not addressed the increasing rates of obesity throughout the entire population. Government provision of effective policy measures, multisectoral cooperation and increasing corporate social responsibility are keys to curbing the trend towards overweight and obesity in China. © 2013 The Authors.

  18. Alcohol under the radar: do we have policy options regarding unrecorded alcohol?

    Lachenmeier, Dirk W; Taylor, Benjamin J; Rehm, Jürgen

    2011-03-01

    According to the World Health Organization, the public health impact of illicit alcohol and informally produced alcohol should be reduced. This paper summarizes and evaluates the evidence base about policy and intervention options regarding unrecorded alcohol consumption. A systematic review of the literature using electronic databases. The literature on unrecorded consumption was sparse with less than 30 articles about policy options, mostly based on observational studies. The most simplistic option to reduce unrecorded consumption would be to lower recorded alcohol prices to remove the economic incentive of buying unrecorded alcohol. However, this may increase the net total alcohol consumption, making it an unappealing public health policy option. Other policy options largely depend on the specific sub-group of unrecorded alcohol. The prohibition of toxic compounds used to denature alcohol (e.g. methanol) can improve health outcomes associated with surrogate alcohol consumption. Cross-border shopping can be reduced by either narrowing the tax differences, or stricter control. Actions limiting illegal trade and counterfeiting include introduction of tax stamps and electronic surveillance systems of alcohol trade. Education campaigns might increase the awareness about the risks associated with illegal alcohol. The most problematic category appears to be the home and small-scale artisanal production, for which the most promising option is to offer financial incentives to the producers for registration and quality control. Even though there are suggestions and theories on how to reduce unrecorded alcohol consumption, there is currently no clear evidence base on the effectiveness or cost effectiveness of available policy options. In addition, the differences in consumption levels, types of unrecorded alcohol, culture and tradition point to different measures in different parts of the world. Thus, the recommendation of a framework for moving forward in decision making

    2005-01-01

    This paper analyzes national and international policy options to encourage the international transfer of technology, distinguishing between four major channels of such transfer: trade in products, trade in knowledge and technology, foreign direct investment, and intranational and international movement of people. A typology of countries and appropriate policy rules of thumb are developed as a guide to both national policymakers and multilateral rule making in the WTO. We argue that the optimal policy mix varies across countries and that there is a need for differentiation in the design and application of rules in trade agreements as well as for a more explicit focus on evaluation of the impacts of policies.

    While the energy crisis of the 1970s stimulated technological innovation in developed countries, it often had the opposite effect in the third world. However, developing countries can be considered to have two types of energy systems: ''connected'' and ''disconnected''. The connected system is affected by changes in the price of commercial energy, but the disconnected system is usually rural and remote. Commercial forms of energy may be needed in the disconnected system, but they are largely unavailable. In some of the developing countries, new energy technologies have therefore been developed which adapt traditional technologies still existing in the disconnected sector. In this article some of the work of the United National Centre for Science and Technology for Development is described. Through its ATAS (Advance Technology Alert System) programme, international and regional workshops are held to discuss policy questions arising in regard to new technologies and developments. Workshops have been held in Moscow on new energy technologies in the industry subsystem (connected), in Guatemala City on new energy technologies and the disconnected system, and in Ottawa on new energy technologies, transportation and development. Initial assessments made by or through these workshops are outlined here. A fourth workshop will be held in June 1990 in Saarbrucken on energy technologies and climate change. (author). 3 figs

  1. The Pacific Islands. Policy options for telecommunications investment.

    Jussawalla, M; Ogden, M R

    1989-03-01

    The Independent Commission for World-Wide Telecommunications Development (Maitland Commission) reported that telecommunication networks, including public telephone systems, are an infrastructure which aids economic development throughout the world. The Commissions objective is to bring the majority of the world's population within easy access of a telephone and, in time, other communications services. Development in the Pacific Islands region is slowed by a lack of efficient communications. The islands are spread over 29 million square kilometers of ocean and extremely vulnerable to natural disasters. Pacific Island Nations (PINs) have problems of foreign exchange, skill shortages, and poor credit terms. Telecommunications infrastructure audits showed the overall regional teledensity of 3 telephones per 100 population. The individual countries vary form 8.3 in Fiji to 1.5 in Papua New Guinea and 25.2 in New Zealand. The population of the developing island countries is in mostly rural areas where there is a chronic shortage of telephones. The constraints on radio systems can be overcome with satellite technology. The new technologies are coming on the market faster than these countries can afford to handle them. By using satellite technology and sharing facilities PINs can greatly reduce the cost of telecommunications systems. Fiber optic cables will be used to carry large volumes of traffic over major routes while satellites can be used for a array of services for the smallest PIN nation to the largest route rim country. Work is being done to standardize the equipment specifications and to develop policies for the coordination of regional telecommunications training. To further facilitate communications development in this area, changes need to be made in international funding priorities for development, and recommendations by the Maitland Commission must be taken seriously.

  2. Policy options for pharmaceutical pricing and purchasing: issues for low- and middle-income countries.

    Pharmaceutical expenditure is rising globally. Most high-income countries have exercised pricing or purchasing strategies to address this pressure. Low- and middle-income countries (LMICs), however, usually have less regulated pharmaceutical markets and often lack feasible pricing or purchasing strategies, notwithstanding their wish to effectively manage medicine budgets. In high-income countries, most medicines payments are made by the state or health insurance institutions. In LMICs, most pharmaceutical expenditure is out-of-pocket which creates a different dynamic for policy enforcement. The paucity of rigorous studies on the effectiveness of pharmaceutical pricing and purchasing strategies makes it especially difficult for policy makers in LMICs to decide on a course of action. This article reviews published articles on pharmaceutical pricing and purchasing policies. Many policy options for medicine pricing and purchasing have been found to work but they also have attendant risks. No one option is decisively preferred; rather a mix of options may be required based on country-specific context. Empirical studies in LMICs are lacking. However, risks from any one policy option can reasonably be argued to be greater in LMICs which often lack strong legal systems, purchasing and state institutions to underpin the healthcare system. Key factors are identified to assist LMICs improve their medicine pricing and purchasing systems.

  3. Policy options for carbon taxation in the EU

    Laurent, Eloi; Le Cacheux, Jacques

    2010-06-01

    Even though the EU clearly leads the global fight against climate change and despite the additional reduction in emissions due to the global crisis and European recession, the ambitious objectives flagged in the '20-20-20 by 2020' strategy and 'climate-energy package' are probably out of reach if a more resolute and consistent policy of carbon taxation is not rapidly put in place. First, the EU is not as 'virtuous' as it may seem, and shows signs of a 'fatigue' in mitigating climate change; this is explained by the weak incentive structure of current climate institutions, due to both narrow coverage and insufficient stringency of the European 'Emission Trading Scheme' (ETS) - the European 'carbon market'-, and to excessive reliance on emission standards combined with weak energy taxation. Fears of losing competitiveness are a major argument against imposing a higher carbon price on industries, feeding tax competition both within the EU and vis-a-vis the rest of the world. Though not fully satisfactory, the Commission's recent proposal (a revision of the 2003 energy taxation directive introducing floors on national excises based on carbon content) would help solving the intra-EU conundrum. Alternatively, an extension of the EU ETS to households and the transport sector via the 'upstream' inclusion of fossil fuel dealers would also be a feasible solution. In order to answer the 'carbon leakage' argument and to send appropriate price signals to European consumers on extra-EU imports, a border adjustment mechanism - carbon levy or inclusion of importers into the EU ETS - is also necessary. Ultimately though, in order to make sure that economic agents face a uniform carbon price, a generalized carbon tax, in the form of a European 'Carbon Added Tax' (ECAT), would be the most effective instrument in the fight against climate change, as well as the pillar of a thorough tax

    Discounted cash flow analysis, including net present value is an established way to value land use and management investments which accounts for the time-value of money. However, it provides a static view and assumes passive commitment to an investment strategy when real world land use and management investment decisions are characterised by uncertainty, irreversibility, change, and adaptation. Real options analysis has been proposed as a better valuation method under uncertainty and where the opportunity exists to delay investment decisions, pending more information. We briefly review the use of discounted cash flow methods in land use and management and discuss their benefits and limitations. We then provide an overview of real options analysis, describe the main analytical methods, and summarize its application to land use investment decisions. Real options analysis is largely underutilized in evaluating land use decisions, despite uncertainty in policy and economic drivers, the irreversibility and sunk costs involved. New simulation methods offer the potential for overcoming current technical challenges to implementation as demonstrated with a real options simulation model used to evaluate an agricultural land use decision in South Australia. We conclude that considering option values in future policy design will provide a more realistic assessment of landholder investment decision making and provide insights for improved policy performance.

    2012-02-01

    Consumption of sugar-sweetened beverages (SSBs) has increased worldwide. As public health studies expose the detrimental impact of SSBs, consumer protection and public health advocates have called for increased government control. A major focus has been on restricting marketing of SSBs to children, but many innovative policy options--legally defensible ways to regulate SSBs and support public health--are largely unexplored. We describe the public health, economic, and retail marketing research related to SSBs (including energy drinks). We review policy options available to governments, including mandatory factual disclosures, earmarked taxation, and regulating sales, including placement within retail and food service establishments, and schools. Our review describes recent international initiatives and classifies options available in the United States by jurisdiction (federal, state, and local) based on legal viability.

    2013-03-01

    Australia suffers from one of the highest prevalences among developed countries of persons being overweight and obese, these conditions arising from the overconsumption of energy-dense, nutrient-poor foods that are generally less expensive than healthier options. One potential avenue for intervention is to influence the price of foods such that healthier options are less expensive and, therefore, are an easier choice to make. This article considers the potential for fiscal policies that would realign food prices with health incentives. Through a review of consumption taxes, consumer subsidies, trade policies, agricultural support policies, and other incentive programs as possible avenues for intervention, this article asks what the Commonwealth Government has already done to help improve Australian diets, and looks at where further improvements could be made.

    Full Text Available This article develops a model to investigate the entry strategies of private investors to the elderly care service market, with the purpose of explaining the reasons behind dilemma of low signing rate plaguing China’s Public-Private Partnership projects. We focus on the competition between two private investors with or without mothballing options under price uncertainty. After the derivation of equilibria of entry strategies, we employ numerical examples to analyze the dependencies of entry thresholds on market parameters, cost parameters, subsidy, and possession of mothballing option. Conclusions are drawn and some policy implications are given with the intention to alleviate the problem of low signing rate.

    2018-01-01

    Full Text Available School nutrition policies provide promising avenues towards the improvement of children’s eating habits and the prevention of obesity. Childhood obesity rates and related chronic diseases are increasing in Queensland, in part as a result of unhealthy eating habits and lack of physical activity. There is a very high investment by the Queensland government in maintaining healthy weight and promoting nutrition and physical activity among schoolchildren through delivering a range of initiatives across the state. However, there is a lack of evidence concerning the effectiveness of nutrition/physical education and parental involvement programs addressing obesity delivered in Queensland schools. This paper can be used to guide government and policy-makers regarding the most effective policy options that will promote healthy eating and physical activity among Queensland schoolchildren. The aim of this paper is to: (i summarize current evidence on Queensland government responses to obesity; and (ii discuss potential policy options that could support healthy eating and regular physical activity, and examine the evidence base for each option and suggest new areas for future research.

    2008-09-01

    The animal husbandry industry is a major emitter of ammonia (NH3), which is a precursor of fine particulate matter (PM2.5)--arguably, the number-one environment-related public health threat facing the nation. The industry is also a major emitter of methane (CH4), which is an important greenhouse gas (GHG). We present an integrated process model of the engineering economics of technologies to reduce NH3 and CH4 emissions at dairy operations in California. Three policy options are explored: PM offset credits for NH3 control, GHG offset credits for CH4 control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane (CH4) gas. Individually these policies vary substantially in the economic incentives they provide for farm operators to reduce emissions. We report on initial steps to fully develop the integrated process model that will provide guidance for policy-makers.

    There are fragmentations in Iran's health insurance system. Multiple health insurance funds exist, without adequate provisions for transfer or redistribution of cross subsidy among them. Multiple risk pools, including several private secondary insurance schemes, have resulted in a tiered health insurance system with inequitable benefit packages for different segments of the population. Also fragmentation might have contributed to inefficiency in the health insurance systems, a low financial protection against healthcare expenditures for the insured persons, high coinsurance rates, a notable rate of insurance coverage duplication, low contribution of well-funded institutes with generous benefit package to the public health insurance schemes, underfunding and severe financial shortages for the public funds, and a lack of transparency and reliable data and statistics for policy-making. We have conducted a policy analysis study, including qualitative interviews of key informants and document analysis. As a result we introduce three policy options: keeping the existing structural fragmentations of social health insurance (SHI)schemes but implementing a comprehensive "policy integration" strategy; consolidation of existing health insurance funds and creating a single national health insurance scheme; and reducing fragmentation by merging minor well-resourced funds together and creating two or three large insurance funds under the umbrella of the existing organizations. These policy options with their advantages and disadvantages are explained in the paper. © 2016 by Kerman University of Medical Sciences.

    Lake Victoria is an international waterbody that offers the riparian communities a large number of extremely important environmental services. Over the past three decades or so, the lake has come under increasing and considerable pressure from a variety of interlinked human activities such as overfishing, species introductions, industrial pollution, eutrophication, and sedimentation. In this paper we examine the root causes for overfishing and pollution in Lake Victoria and give possible policy options that can help remediate or mitigate the environmental degradation.

    Ocean acidification has emerged over the last two decades as one of the largest threats to marine organisms and ecosystems. However, most research efforts on ocean acidification have so far neglected management and related policy issues to focus instead on understanding its ecological and biogeochemical implications. This shortfall is addressed here with a systematic, international and critical review of management and policy options. In particular, we investigate the assumption that fighting acidification is mainly, but not only, about reducing CO2 emissions, and explore the leeway that this emerging problem may open in old environmental issues. We review nine types of management responses, initially grouped under four categories: preventing ocean acidification; strengthening ecosystem resilience; adapting human activities; and repairing damages. Connecting and comparing options leads to classifying them, in a qualitative way, according to their potential and feasibility. While reducing CO2 emissions is confirmed as the key action that must be taken against acidification, some of the other options appear to have the potential to buy time, e.g. by relieving the pressure of other stressors, and help marine life face unavoidable acidification. Although the existing legal basis to take action shows few gaps, policy challenges are significant: tackling them will mean succeeding in various areas of environmental management where we failed to a large extent so far.

    Full Text Available Public health action to reduce dietary salt intake has driven substantial reductions in coronary heart disease (CHD over the past decade, but avoidable socio-economic differentials remain. We therefore forecast how further intervention to reduce dietary salt intake might affect the overall level and inequality of CHD mortality.We considered English adults, with socio-economic circumstances (SEC stratified by quintiles of the Index of Multiple Deprivation. We used IMPACTSEC, a validated CHD policy model, to link policy implementation to salt intake, systolic blood pressure and CHD mortality. We forecast the effects of mandatory and voluntary product reformulation, nutrition labelling and social marketing (e.g., health promotion, education. To inform our forecasts, we elicited experts' predictions on further policy implementation up to 2020. We then modelled the effects on CHD mortality up to 2025 and simultaneously assessed the socio-economic differentials of effect.Mandatory reformulation might prevent or postpone 4,500 (2,900-6,100 CHD deaths in total, with the effect greater by 500 (300-700 deaths or 85% in the most deprived than in the most affluent. Further voluntary reformulation was predicted to be less effective and inequality-reducing, preventing or postponing 1,500 (200-5,000 CHD deaths in total, with the effect greater by 100 (-100-600 deaths or 49% in the most deprived than in the most affluent. Further social marketing and improvements to labelling might each prevent or postpone 400-500 CHD deaths, but minimally affect inequality.Mandatory engagement with industry to limit salt in processed-foods appears a promising and inequality-reducing option. For other policy options, our expert-driven forecast warns that future policy implementation might reach more deprived individuals less well, limiting inequality reduction. We therefore encourage planners to prioritise equity.

    Surgical Heller myotomy has high rates of successful long-term results, but failed cases still remain. Moreover, the treatment strategy in patients with surgical myotomy failure is controversial. Recently, peroral endscopic myotomy (POEM) was reported to be efficient and safe in primary treatment of achalasia. In this study, we aimed to evaluate the efficacy and safety of POEM for surgical myotomy failure as a rescue second-line treatment, and we discuss the treatment options adapted in achalasia recurrence. A total of 315 consecutive achalasia patients received POEM from September 2008 to December 2012 in our hospital. Eleven (3.5%) patients who had persistent or recurrent achalasia and had received surgical myotomy as a first-line treatment from other hospitals were included in this study. Patient background, barium swallow studies, esophagogastroduodenoscopy (EGD), manometry, and symptom scores were prospectively evaluated. In principle, all patients in whom surgical myotomy failed received pneumatic balloon dilatation (PBD) as the first line "rescue" treatment, and only if PBD failed were patients considered for rescue POEM. The PBD alone was effective in 1 patient, and in the remaining 10 patients, rescue POEM was performed successfully without complications. Three months after rescue POEM, significant reduction in lower esophageal sphincter (LES) resting pressures (22.1 ± 6.6 mmHg vs 10.9 ± 4.5 mmHg, p myotomy were excellent. Long-term results are awaited. Copyright © 2013 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

  4. Renewable energy and policy options in an integrated ASEAN electricity market: Quantitative assessments and policy implications

    2015-01-01

    Energy market integration (EMI) in the ASEAN region is a promising solution to relieve the current immobilization of its renewable energy resources and would serve the fast increasing demand for electricity in the region. EMI could be further extended with coordinated policies in carbon pricing, renewable energy portfolio standards (RPS), and feed-in-tariffs (FIT) in the ASEAN countries. Using a linear dynamic programming model, this study quantitatively assesses the impacts of EMI and the above-mentioned policies on the development of renewable energy in the power generation sector of the region, and the carbon emissions reduction achievable with these policies. According to our results, EMI is expected to significantly promote the adoption of renewable energy. Along with EMI, FIT appears to be more cost-effective than RPS and is recommended for the ASEAN region, albeit political barriers for policy coordination among the countries might be a practical concern. In addition, an RPS of 30% electricity from renewable sources by 2030, which is considered politically a “low-hanging fruit”, would achieve moderate improvements in carbon emissions reductions and renewable energy development, while incurring negligible increases in the total cost of electricity. -- Highlights: •Energy market integration (EMI), carbon pricing, RPS, and FIT are examined for ASEAN. •EMI is a promising and feasible solution to promote renewable energy for ASEAN. •Along with EMI, FIT appears to be more cost-effective than RPS for ASEAN. •RPS of 30% by 2030 appears to be reasonable and feasible for ASEAN. •Coordinating FIT and RPS policies under EMI among ASEAN is advised

  5. Technical backgrounder to CAPP input on June 14, 2002 workshop on federal climate change policy options

    International Nuclear Information System (INIS)

    2002-06-01

    This paper presents arguments regarding the Federal Discussion Paper on Climate Change which presents four options for Canada to implement the Kyoto Protocol. This paper describes some major flaws with the package. The Canadian Association of Petroleum Producers (CAPP) believes that policy on climate change should ensure that measures for the trade exposed industry sectors are based on achievable objectives and that all levels of government should take a coordinated approach to greenhouse gases. In addition there should be no unfair burden on any region or unfairness in any sector. Climate change policy objectives should also consider economic, environmental and social objectives. With respect to the Kyoto Protocol in particular, governments should assess the liability that ratification would create and determine whether it makes economic sense. CAPP argues that none of the four options in the federal discussion paper meets requirements for industry objectives and form of policies. In addition, if Canada does not shift industry and emissions to other countries, or buy foreign credits, energy use by consumers would have to be significantly reduced in order to meet the Kyoto target. It was also noted that if the 'polluter pay' policy proposal is to be adopted, it must be based on a thorough understanding of what it implies and be applied in such a way to reflect the reality of international markets

    In this paper we capture and synthesize the unique knowledge of experts so that choices regarding policy measures to address methamphetamine consumption and dependency in Australia can be strengthened. We examine perceptions of the: (1) influence of underlying factors that impact on the methamphetamine problem; (2) importance of various models of intervention that have the potential to affect the success of policies; and (3) efficacy of alternative pseudoephedrine policy options. We adopt a multi-criteria decision model to unpack factors that affect decisions made by experts and examine potential variations on weight/preference among groups. Seventy experts from five groups (i.e. academia (18.6%), government and policy (27.1%), health (18.6%), pharmaceutical (17.1%) and police (18.6%)) in Australia participated in the survey. Social characteristics are considered the most important underlying factor, prevention the most effective strategy and Project STOP the most preferred policy option with respect to reducing methamphetamine consumption and dependency in Australia. One-way repeated ANOVAs indicate a statistically significant difference with regards to the influence of underlying factors (F(2.3, 144.5)=11.256, pmethamphetamine consumption and dependency. Most experts support the use of preventative mechanisms to inhibit drug initiation and delayed drug uptake. Compared to other policies, Project STOP (which aims to disrupt the initial diversion of pseudoephedrine) appears to be a more preferable preventative mechanism to control the production and subsequent sale and use of methamphetamine. This regulatory civil law lever engages third parties in controlling drug-related crime. The literature supports third-party partnerships as it engages experts who have knowledge and expertise with respect to prevention and harm minimization. Copyright © 2016 Elsevier B.V.

    2014-01-01

    Nowadays the control of greenhouse gas is probably the most challenging environmental policy issue. Since CO 2 is considered the major greenhouse gas (GHG) that contributes to the global warming, enforcing technological strategies aiming to avoid or reuse CO 2 emissions becomes crucial, in order to mitigate GHG environmental impact. Currently, solutions conventionally adopted to this purpose are carbon capture and storage (CCS) technologies. In this context, instead, the followed strategy aims to further improvements in energetic conversion efficiency with related reduced specific CO 2 emissions (per produced kWh e ). Therefore, with particular reference to the electric power generation, this paper proposes an innovative energy conversion system, based on solid oxide fuel cell (SOFC), characterized by higher efficiency and reduced CO 2 emission factor respect to an analogous conventional energy plant. In particular, the innovative solution consists of combining SOFC to methane dry reforming technology, while the conventional system refers to steam methane reforming-SOFC coupling. The innovative system performance up to 65% electric efficiency as cited in the paper, was validated through simulations carried out in Aspen Plus environment. - Highlights: • An innovative high efficiency plant with low CO 2 emissions is presented. • The new solution combined SOFC to methane dry reforming technology (CDR–SOFC). • A comparison between CDR–SOFC and SMR–SOFC system was carried out in Aspen Plus. • CDR–SOFC efficiency is greater of 6.4% percentage points respect to SMR–SOFC. • A CO 2 emission factor reduction of about 10% was achieved by CDR–SOFC plant

    2010-03-01

    Context and aims Internationally, the repertoire of alcohol pricing policies has expanded to include targeted taxation, inflation-linked taxation, taxation based on alcohol-by-volume (ABV), minimum pricing policies (general or targeted), bans of below-cost selling and restricting price-based promotions. Policy makers clearly need to consider how options compare in reducing harms at the population level, but are also required to demonstrate proportionality of their actions, which necessitates a detailed understanding of policy effects on different population subgroups. This paper presents selected findings from a policy appraisal for the UK government and discusses the importance of accounting for population heterogeneity in such analyses. Method We have built a causal, deterministic, epidemiological model which takes account of differential preferences by population subgroups defined by age, gender and level of drinking (moderate, hazardous, harmful). We consider purchasing preferences in terms of the types and volumes of alcoholic beverages, prices paid and the balance between bars, clubs and restaurants as opposed to supermarkets and off-licenses. Results Age, sex and level of drinking fundamentally affect beverage preferences, drinking location, prices paid, price sensitivity and tendency to substitute for other beverage types. Pricing policies vary in their impact on different product types, price points and venues, thus having distinctly different effects on subgroups. Because population subgroups also have substantially different risk profiles for harms, policies are differentially effective in reducing health, crime, work-place absence and unemployment harms. Conclusion Policy appraisals must account for population heterogeneity and complexity if resulting interventions are to be well considered, proportionate, effective and cost-effective.

    Overweight and obesity increases risks for many diseases, while treating them is expensive. Trends in the prevalence of overweight and obesity over the last two decades indicate the need for urgent interventions. Several different kinds of interventions could modify the obesogenic environment. The aim of this study was to map which policy options will be acceptable and effective in Hungary. Interviews were conducted with 21 stakeholders representing a wide range of viewpoints to evaluate seven core and 13 discretionary policy options under different criteria. The 21 Hungarian participants used 92 appraisal criteria covering a wide range of issues. Efficacy, practical feasibility, social acceptability and societal benefits were widely judged more important than the costs of measures. Significant additional social and health benefits were anticipated from changes in transport and planning policies, but the cost to the public sector was considered high and the implementation difficult. There was broad support for changes in patterns of food consumption and levels of physical activity. There was a consensus that without developing the attitudes of individuals to be more responsible for their health, environmental changes alone would not be enough to reverse the trend of the growing prevalence of obesity.

    Strikes by junior hospital doctors over the issue of on-call remuneration in Denmark and Sweden in 1981 are analyzed to clarify the impact of public-sector cost-control policies on intra- and interprofessional solidarity within the Scandinavian professional peak associations. The junior doctors' grievances could find expression either through increased "voice" within the medical negotiating machinery, or by pursuing the exit option in having the medical associations quit the peak associations. The article explains why the "exit" option was selected in Denmark, while in Sweden the granting of additional voice helped persuade the medical association to withdraw its exit threat and to remain within the peak association. The two cases are interpreted as presaging a divergence in the paths being taken by the various Scandinavian welfare states.

    Recently, a study has been carried out for DG Environment of the European Commission titled 'Market-based instruments for Reducing Air Pollution. Assessment of Policy Options to reducing air pollution from shipping'. Within this study it was decided to study the environmental impact of two legally possible trading systems: a voluntary emissions trading system for all sea areas belonging to the European Union and a mandatory emissions trading system for the ports and territorial waters of EU Member States. If the emissions in ports and coastal waters will be made part of such a trading system it can result in lower environmental exposure for the population. [nl

    Policy options for research, development and diffusion of the products of marker-assisted selection (MAS) depend on the development objectives and priorities of the agricultural sector, its various subsectors and cross-cutting activities dealing with science and technology (S and T), including biotechnology and the management of genetic resources. The policy agenda in each of these areas has shifted from the traditional focus of 'raising productivity' to a broader agenda of improving rural livelihoods in both economic and non-economic terms in support of the Millennium Development Goals (MDGs). Securing financial commitments from national governments and donors to invest in MAS and related molecular approaches requires more active engagement by national agricultural research and extension systems (NARES) in the processes of revising poverty reduction strategy papers (PRSPs), and in developing policies and strategies for agricultural development, S and T and genetic resources. Agriculture and agricultural S and T are undergoing rapid change but few developing countries have either agricultural S and T or biotechnology policies. They need to develop these to build coherence across the agricultural sector including delineating the roles of public and private sector entities, and as a means to strengthen accountability with respect to priority setting, monitoring and evaluating the outcomes and impacts of both research and practical applications of MAS. Options are provided for developing and implementing MAS programmes and projects, for setting priorities and evaluating outcomes and impacts. Given the uncertain nature of technical change and the long time frames that often characterize translation of the research and extension services provided by NARES into sustainable improvements in productivity and livelihoods through genetic enhancement, it is concluded that greater emphasis needs to be placed on research to analyse systematically the critical paths involved in

    Myriad policy measures aim to reduce greenhouse gas emissions from the electricity sector, promote generation from renewable sources, and encourage energy conservation. To what extent do innovation and energy efficiency (EE) market failures justify additional interventions when a carbon price is in place? We extend the model of Fischer and Newell (2008) with advanced and conventional renewable energy technologies and short and long-run EE investments. We incorporate both knowledge spillovers and imperfections in the demand for energy efficiency. We conclude that some technology policies, particularly correcting R and D market failures, can be useful complements to emissions pricing, but ambitious renewable targets or subsidies seem unlikely to enhance welfare when placed alongside sufficient emissions pricing. The desirability of stringent EE policies is highly sensitive to the degree of undervaluation of EE by consumers, which also has implications for policies that tend to lower electricity prices. Even with multiple market failures, emissions pricing remains the single most cost-effective option for reducing emissions.

    1986-07-01

    Prior to the TMI-2 accident on March 28, 1979, four nuclear power plant units that had previously been issued a construction permit were cancelled, principally because of reduced projections of regional power demand. Since that time, an additional 31 units with CPs have been cancelled and eight units deferred. On December 23, 1985 one of the deferred units (Limerick-2) was reactivated and construction resumed. The primary objective of this policy study is to identify the principal issues requiring office-level consideration in the event of reactivation of the construction of one or more of the nuclear power plants falling into two categories: (1) LWR units issued a construction permit whose construction has been cancelled, and (2) LWR units whose construction has been deferred. The study scope is limited to identifying regulatory issues or questions deserving analysis rather than providing, at this time, answers or recommended actions. Five tasks are addressed: a tabulation and discussion of the status of all cancelled and deferred LWR units; and identification of potential safety and environmental issues; an identification of regulatory or policy issues and needed information to determine the desirability of revising certain rules and policies; and identification of regulatory options and decision criteria; and an identification of decision considerations in determining staff requirements and organizational coordination of LWR reactivation policy and implementation efforts. 41 refs

    2012-01-01

    China promulgated the Medium and Long-Term Development Plan for Renewable Energy in 2007, which included sub-targets of 2010 and 2020 for various renewable energy technologies. Almost all the 2010 sub-targets have been met and even surpassed except non-grain fuel ethanol. There is debate surrounding the questions of whether and how the country will be able to meet the 2020 biofuels target. This paper provides the assessment of potential technology pathways to achieve the 2020 target regarding their respective resource potential and supply cost. Barriers and policy options are identified based on broad literatures review. And an overview of biofuels projections is presented to provide insight into the comparison of various policy scenarios. The study shows that China can potentially satisfy non-grain fuel ethanol target by 2020 from technology perspective. But she will probably fall far short of this target if current situations continue. Additional policy efforts are needed. Meanwhile, the target of biodiesel production has high probability to be achieved. However, if given support policies, it will develop better. - Highlights: ► I. Non-grain feedstocks such as cassava, sweet sorghum and sweet potato grown in low productive arable lands or unutilized lands have enough potential to meet ethanol targets in 2020. ► II. If current situations continue, China will fall far short of the 2020 target. ► III. The target of biodiesel production has high probability to be achieved, while, if given support policies, it will develop better. ► IV. Supply cost is one of the major barriers faced by all biofuels pathways. ► V. Various policy measures would be necessary to overcome the costs barriers to biofuels in China.

    The US Department of Energy (DOE) has recognized the opportunity to achieve energy, economic, and environmental benefits by promoting energy-efficient lighting through federal policies, including lighting standards, financial incentives, and information programs. To assist in this process, the Office of Conservation and Renewable Energy's Office of Codes and Standards invited Lawrence Berkeley Laboratory to assess prospective national impacts for a variety of policy options. Some progress has already been made in developing lighting policies at both the federal and state levels. The US DOE's Office of Building Technologies has evaluated lighting efficiency incentives as part of its analysis for the National Energy Strategy. Fluorescent and incandescent lamp standards are included in the national Energy Policy Act of 1992 (P.L. 102-486, October 24, 1992). A few states have analyzed or implemented lamp and luminaire standards. Many policy-related issues merit further investigation. For example, there is considerable debate over issues such as mandatory or voluntary standards versus component labeling and other education-oriented strategies. Several different technologies are involved that interact with each other-lamps (incandescent, compact fluorescent, and HID), ballasts (for fluorescent and HID lamps), and fixtures with reflectors and lenses. Control systems and operation patterns must also be considered (timers, automated dimming, or occupancy sensors). Lighting applications are diverse, ranging from offices, restaurants, hallways, hospital operating rooms, to exterior lights. Lighting energy use influences heating and cooling requirements in buildings. Successful lighting system design must also address interactions between architectural design elements and daylighting availability. Proper system installation and ongoing operation and maintenance are crucial. The economic aspects of the preceding points must also be considered for policy making.

    In the area of energy efficiency, advanced technologies combined with best practices appear to afford not only large, but also cost-effective options to conserve energy and reduce greenhouse gas emissions (McKinsey & Company, 2007). In practice, however, the realization of this potential has often proven difficult. Progress appears to require large numbers of individuals to act knowledgeably, and each individual must often act with enabling assistance from others. Even when consumer education is effective and social norms are supportive, the actions of individuals and businesses can be impeded by a broad range of barriers, many of which are non-technical in nature. Title XVI of the Energy Policy Act of 2005 included a mandate to examine barriers to progress and make recommendations in this regard. A detailed report on barriers as well as the National strategy for overcoming barriers met this requirement (Brown et al, 2008; CCCSTI, 2009). Following up on this mandate, the U.S. Climate Change Technology Program (CCTP) chose to focus next on the development of policy options to improve energy efficiency in residential buildings, with supporting analysis of pros and cons, informed in part by behavioral research. While this work is sponsored by CCTP, it has been undertaken in coordination with DOE's Building Technologies Program and Office of Electricity Delivery and Energy Reliability.

    This paper explores modified hospital casemix payment formulae that would refine the diagnosis-related group (DRG) system in Victoria, Australia, which already makes adjustments for teaching, severity and demographics. We estimate alternative casemix funding methods using multiple regressions for individual hospital episodes from 2001 to 2003 on 70 high-deficit DRGs, focussing on teaching hospitals where the largest deficits have occurred. Our casemix variables are diagnosis- and procedure-based severity markers, counts of diagnoses and procedures, disease types, complexity, day outliers, emergency admission and "transfers in." The results are presented for four policy options that vary according to whether all of the dollars or only some are reallocated, whether all or some hospitals are used and whether the alternatives augment or replace existing payments. While our approach identifies variables that help explain patient cost variations, hospital-level simulations suggest that the approaches explored would only reduce teaching hospital underpayment by about 10%. The implications of various policy options are discussed.

    To identify the policy implications of the magnitude and characteristics of alcohol consumption and problems, viewed globally, and to summarize conclusions on the effectiveness of the strategies available to policymakers concerned with reducing rates of alcohol problems. This summative article draws on the findings of the articles preceding it and of reviews of the literature. Overall volume of consumption is the major factor in the prevalence of harms from drinking. Since consumption and associated problems tend to increase with economic development, policymakers in developing economies should be especially aware of the need to develop policies to minimize overall increases in alcohol consumption. Unrecorded consumption is also an important consideration for policy in many parts of the world, and poses difficulties for alcohol control policies. Drinking pattern is also an important contributing factor toward alcohol-related harm. Although some drinking patterns have been shown to produce beneficial health effects, because the net effect of alcohol on coronary disease is negative in most parts of the world, policies that promote abstinence or lower drinking overall may be the safest options. Moreover, sporadic intoxication is common in many parts of the world, and policies are unlikely to change this drinking pattern at least in the short to medium term. At the same time, because injuries comprise a large proportion of the burden of alcohol, it is appropriate to enhance these policies with targeted harm reduction strategies such as drinking and driving countermeasures and interventions focused on reducing alcohol-related violence in specific high-risk settings. Alcohol consumption is a major factor for the global burden of disease and should be considered a public health priority globally, regionally, and nationally for the vast majority of countries in the world. The need for alcohol policy is even stronger when it is taken into consideration that the burden of

These include enhanced FFS payment for office visits to the PCMH; paying additional FFS for "new" PCMH services; variations of traditional FFS combined with new PCMH-oriented per patient per month capitation; and combined capitation payments for traditional primary care medical services as well as new medical home services. In discussing options for PCMH payment reform we consider issues in patient severity adjustment, performance payment, and the role of payments to community service organizations to collaborate with the PCMH. We also highlight some of the practical challenges that can complicate reimbursement reform for primary care and the PCMH. Through this discussion we identify key dimensions to provider payment reform relevant to promoting enhanced primary care through the patient centered medical home. These consist of paying for the basic medical home services, rewarding excellent performance of medical homes, incentivizing medical home connections to other community health care resources, and overcoming implementation challenges to medical home payments. Each of these overarching policy issues invokes a substantial subset of policy relevant research questions that collectively comprise a robust research agenda. We conclude that the conceptual strengths and weaknesses of available payment models for medical home functions invoke a complex array of options with varying levels of real-world feasibility. The different needs of patients and communities, and varying characteristics of practices must also be factors guiding PCMH payment reform. Indeed, it may be that different circumstances will require different payment approaches in various combinations.

    This paper considers several policy options which have been proposed to improve the functioning of the ETS. These options require an intervention either on the ETS cap (−30% target, set-aside, carbon central bank, long-term target) or on the carbon price (European and national price floor). We analyse the impact of each policy on the ETS carbon price and emissions. A multi-criteria evaluation method is applied to compare the policy options against a plurality of environmental, economic and procedural criteria. We find that the final ranking depends on the goals to be achieved, i.e., the relative weights attributed to the criteria. When policymakers want mainly to support the carbon price both in the short and long-run, while improving ETS flexibility and harmonization, the CCB and the EU price floor are, respectively ranked as first and second-best options. As the preference for environmental and implementation goals gradually increases, the position of the EU price floor and CCB options tend to invert. The −30% target should be adopted when reducing emissions is the priority goal, while a national price floor is the worst option, in this case. Nevertheless, self-interested States looking for a relatively quick, feasible solution, may find it optimal. - Highlights: ► A multi-criteria analysis is adopted to compare policy options to improve the ETS effectiveness. ► An ETS cap reversible adjustment by a carbon central bank is the first-best option. ► The establishment of a EU-wide price floor would represent a second-best solution. ► A national price floor is the worst option but self-interest states may find it optimal. ► A post-2020 target is not a mutually exclusive option and should be set

    Full Text Available Socio-environmental problems, such as climate change, pollution and habitat destruction, present serious challenges for fisheries economic development. The integration of interventions or investments within a coastal marine ecosystem, a defined spatial area, is considered important in the economic development of local communities leading to the planned outcomes of livelihoods, food security and conservation The coastal marine ecosystem, is the provider of products and services to the local economy adjacent to the ecosystem where the benefit flows, within that area, are interconnected. The roles of science, technology and innovation (STI are an integral part of these multi-dimensional interventions. Hence the need for an integrated approach for these interventions by government and/or through donor funded projects to enhance economic development of coastal communities. The policy framework proposed is therefore an STI perspective of the links between these intervention and investment options, based on a ‘fisheries economic development Hub’ (Hub and discussed using the multi-level perspective (MLP. The policy innovation proposal suggests an implementation strategy of a pilot project and analyses the selection and implications of a potential Indonesian site for the application of the Hub.

    This document presented a framework for future Canadian action in designing effective climate policies. The document provided background information on the rationale for reducing greenhouse gas emissions and discussed how much and how quickly. It also discussed Canada-specific targets. The author cautioned that the threat of anthropogenic climate change is worth insuring against and presented a number of criteria for evaluating potential premiums Canadians might pay for an insurance policy. Other options such as subsidies and offsets were also discussed, as well as emission taxation. The document also included a novel suggestion for a carbon-management standard that would apply to all producers and importers of fossil fuels for domestic use. It was concluded that energy efficiency is more expensive to achieve than advocates suggest, but an understanding of this fact is critical if greenhouse gas abatement policies are to be well designed. In addition, subsidies and information programs are largely ineffective by themselves. The author suggested that a carbon tax would be the most economically efficient and administratively simple way to price the atmosphere. 34 refs., 2 figs.

    Forecasts of U.K. energy consumption in this sector for four future scenarios based on different economic growth rates, energy prices, and energy conservation policies, show that by the year 2000, private transport will probably account for 76-94% of total energy consumption in surface passenger transport. A 33% increase in the average miles-per-gallon fuel consumption through technological improvements in private vehicles, conversion of private vehicles to diesel oil, additional fuel taxation equivalent to 25 or 50% fuel price increase, a 10% reduction in average car engine size (encouraged by taxation), and changes in public transport technology offer energy savings of about 20, 5-10, 6.3 or 12.5, 2-4, and 2%, respectively. There is considerable uncertainty about the outcome of these options.

    Changes in consumer behaviour can lead to major reductions in greenhouse gas emissions in the European Union, particularly in the areas of transport, housing and food. Behavioural changes can complement technological changes and can allow emission reduction targets to be achieved more cost-effectively overall. The study identifies 36 options for behavioural change that would cut greenhouse gas emissions. Of these, 11 particularly relevant options have been studied in detail. They include shifting to a more healthy and balanced diet, eating less meat and dairy products, buying and using a smaller car or an electric car, teleworking, adjusting room temperature and optimising ventilation. For each of the behavioural changes studied in depth, emission reduction potentials have been quantified for 2020, 2030 and 2050. The study identifies barriers to implementing the changes, and quantifies the likely effects of policy packages which could overcome these barriers. The results show that the behavioural changes that could take place simultaneously have the potential to save emissions totalling up to about 600 million tonnes of CO2-equivalent a year in 2020. This is about one-quarter of the projected annual emissions from sectors not covered by the EU emissions trading system. The savings potential is particularly high in the area of food.

    A quantitative general economic model has been developed for options available in greenhouse gas abatement policy concerning energy use. It has been applied in three exercises to explore the effects of energy taxes on the United Kingdom economy. One of these examined the effect of the proposed European Commission carbon/energy tax; the second attempts to set out a policy framework which would enable the UK to reach the IPCC target of 60% reduction in CO 2 emissions by 2040 and explores the economic implications; the third compares the proposal of the UK government to levy VAT on domestic fuel with the EC carbon/energy tax. Additionally, estimates have been made of the secondary benefits of reducing CO 2 emissions. The results present a striking contrast to much of the literature. They include the conclusions that: the EC carbon/energy tax would have negligible macroeconomic effects on the UK economy providing revenues were recycled in such a way as to neutralise inflation; reduction of UK CO 2 emissions by 60% would not necessarily cause great economic disruption; the secondary benefits of reducing CO 2 emissions are of sufficient size to alter radically the benefit cost profile of carbon abatement; equity and efficiency should be regarded as complementary, not competing, objectives in the abatement of CO 2 emissions from the domestic sector.

  15. A successful Charter challenge to medicare? Policy options for Canadian provincial governments.

    Flood, Colleen M; Thomas, Bryan

    2018-03-26

    In September 2016, a case went to trial in British Columbia that seeks to test the constitutionality of provincial laws that (1) ban private health insurance for medically necessary hospital and physician services; (2) ban extra-billing (physicians cannot charge patients more than the public tariff); and (3) require physicians to work solely for the public system or 'opt-out' and practice privately. All provinces have similar laws that have been passed to meet the requirements of federal legislation, the Canada Health Act (and thus qualify for federal funds). Consequently, a finding of unconstitutionality of one or more of these laws could have a very significant impact on the future of Canada's single-payer system ('medicare'). However, should the court find that a particular law is not in compliance with the Canadian Charter of Rights and Freedoms, the baton is then passed back to the government which may respond with other laws or policies that they believe to be constitutionally compliant. The ultimate impact of any successful Charter challenge to laws protecting medicare from privatization will thus significantly depend on how Canadian governments respond. Provincial governments could allow privatization to undercut equity and access, or they could respond creatively with new legal and policy solutions to both improve equity and access and tackle some of the problems that have long bedeviled Canadian medicare. This paper provides an understanding - grounded in comparative health systems evidence - of law and policy options available to Canadian lawmakers for limiting two-tier care in the wake of any successful challenge to existing laws. The paper presents the results of a large inter-disciplinary, comparative study, started in 2015, that systematically reviewed the legal and broader regulatory schemes used to regulate the public/private divide in 15 Organization for Economic Co-Operation and Development countries with a particular eye to what the effect of

    The standard treatment of necrotizing soft tissue infection (NSTI) includes extensive surgical debridement. Care of these debridements is challenging because of the size of the wound and associated pain. A potential solution is to leave the wounds open-to-air in the period after the initial debridement, allowing for regular inspection at bedside while reducing pain associated with frequent dressing changes. We evaluated the feasibility of this approach from a pain control standpoint. An audit of wound care modalities used on adult patients with NSTI admitted to a regional burn center between January 2009 and May 2014 was performed. Patients with at least one operation were included. Those opting for palliative care were excluded. Wound care was divided into four categories: open-to-air (OTA), negative-pressure wound therapy (NPWT), packing, and ointment. Wound care, pain score, pain medication use, and number of operations were collected for the first seven days after initial debridement. Pain management was assessed by pain scores. Analgesic use was measured and compared using conversion to morphine milligram equivalents (MME). Ninety-six patients were included; 67% were men with average age of 50 years, resulting in a total of 672 days of wound care evaluated: 69 days of OTA, 127 days of NPWT, 200 days of packing, and 126 days of ointment (150 days were undocumented). Average daily pain score from all wound care modalities was 2.00. Negative pressure wound therapy had the highest reported daily pain score (2.18, p = 0.034), whereas OTA had the lowest pain score (1.63, p < 0.05). Mortality was lower in the OTA cohort but was not statistically significant; there were no other differences in long-term outcome. Leaving wounds OTA is a safe and viable option in the immediate post-debridement period of NSTI to reduce pain, while permitting frequent re-evaluation for quick recognition of disease progression and repeat operative debridement if necessary.

    Biomass as a renewable energy source holds a great potential in responding to energy challenges of the future as well as meeting renewable energy targets set by the European Union. The objective of this study was to analyse various policy options and implementation measures promoting electricity from renewable biomass in the European Union, including new Member States (EU-25). The main political driving force behind this investigation was the RES-E Directive (2001/77/EC). The effectiveness of policy instruments regarding the development of electricity from biomass and biogas in the period of 1990-2002, and the framework conditions, i.e. success and risk factors, for this progress were assessed though a 'five-step approach'. Past development in terms of bioelectricity production and generating capacity was assessed based on statistics of Eurostat and the IEA. Policy instruments promoting bioelectricity and the framework factors on the national level in each EU Member State (excluding Cyprus and Malta) were investigated using the EU and governmental documents, independent evaluations and expert contacts as information sources. It became clear that determination of the effectiveness of policy instruments cannot be separated from the environment these mechanisms are applied to: mapping of the frame conditions for development is essential. Instead of selecting distinct policy instruments, successful Member State/bioelectricity combinations were chosen. The most successful combinations were found to be Germany, United Kingdom, Spain and Finland, whereas examples of unsuccessful measures were found in Greece, Luxembourg and the new Member States. Bioelectricity has clearly benefited from feed-in tariff system in countries like Germany but the use of biomass has essentially increased even without this measure in Sweden and Finland, where favourable taxation and strong links between forestry and power industries are defining factors for positive development.

    This report examines various policy design options for a future 'Supplier Obligation' to promote energy efficiency in the domestic sector. It examines possible reasons that low-cost energy efficiency measures have not been taken up to the extent predicted by simple models of household financial decision-making. Having characterised these 'barriers' to energy efficiency we review a range of policy designs that could be considered to reduce household CO{sub 2} emissions. We then evaluate these options against a range of criteria and suggest areas for further research. There is a substantial literature on the barriers to energy efficiency both within households and more generally across the economy. Based on this literature, w e have identified seven categories of 'barriers'. Briefly, these include: Basic financial barriers: These include the potentially higher (upfront) costs of energy efficient products and the interest rates available to households; Hidden costs: These include 'transaction costs' associated with finding reputable providers, time costs of disruption, and the costs of differences in quality of product or service - all of which may reduce the net benefit derived from efficiency measures. Lack of information: If households do not know their level of energy expenditure, how energy use can be reduced, by how much, or at what cost, they are unlikely to consider investing in energy efficiency. Risks and uncertainty: Uncertainty about future energy prices or period of tenure may deter households from investing, since they cannot be assured of future savings. In addition, households may be wary of the risk associated with new (or unfamiliar) products or services. Poorly aligned incentives: The most commonly cited barrier of this kind is the 'landlord-tenant split, whereby landlords under-invest in energy-efficiency because tenants pay energy bills, or tenants do not economise on energy because the landlord pays

    The Sulu-Sulawesi Sea, with neighboring Indonesian Seas and South China Sea, lies at the center of the world's tropical marine biodiversity. Encircled by 3 populous, developing nations, the Philippines, Indonesia and Malaysia, the Sea and its adjacent coastal and terrestrial ecosystems, supports ca. 33 million people, most with subsistence livelihoods heavily reliant on its renewable natural resources. These resources are being impacted severely by rapid population growth (> 2% yr-1, with expected doubling by 2035) and widespread poverty, coupled with increasing international market demand and rapid technological changes, compounded by inefficiencies in governance and a lack of awareness and/or acceptance of some laws among local populations, particularly in parts of the Philippines and Indonesia. These key root causes all contribute to illegal practices and corruption, and are resulting in severe resource depletion and degradation of water catchments, river, lacustrine, estuarine, coastal, and marine ecosystems. The Sulu-Sulawesi Sea forms a major geopolitical focus, with porous borders, transmigration, separatist movements, piracy, and illegal fishing all contributing to environmental degradation, human suffering and political instability, and inhibiting strong trilateral support for interventions. This review analyzes these multifarious environmental and socioeconomic impacts and their root causes, provides a future prognosis of status by 2020, and recommends policy options aimed at amelioration through sustainable management and development.

  1. Mathematical modeling for exploring the effects of overtime option, rework, and discontinuous inventory issuing policy on EMQ model

    Full Text Available This study employs mathematical modeling to explore the effects of overtime option, rework, and discontinuous end-item issuing policy on the economic manufacturing quantity (EMQ model. Conventional EMQ model assumed that all products fabricated are of good quality and are issued under continuous policy. In real world, however, nonconforming items are randomly produced, due to diverse unexpected factors in fabrication process. When finished items are to be distributed to outside locations, discontinuous multi-shipment policy is often used rather than continuous rule. In addition, with the intention of increasing short-term capacity or shortening replenishment cycle length to smooth the production planning, adopting overtime option can be an effective strategy. To cope with the aforementioned features in real production systems, this study incorporates overtime option, rework, and multi-shipment policy into the EMQ model and explores their joint effects on optimal lot size and number of shipments, and on other relevant system parameters. Mathematical modeling and Hessian matrix equations enable us to derive the optimal policies to the problem. Through the use of numerical example, the applicability of research result is exhibited and a variety of significant effects of these features on the proposed system are revealed.

  2. Carbon accounting of forest bioenergy: from model calibrations to policy options (Invited)

    2013-12-01

    Programs to stimulate biomass use for the production of heating/cooling and electricity have been implemented in many countries as part of their greenhouse gas emission reduction strategies. Critiques claim however that the use of forest biomass, e.g. as a replacement of hard-coal in large-scale power plants or mineral oil fuelled residential heating boilers, countervails carbon saving and thus also climate change mitigation strategies, at least in the short-term, as forest biomass combustion releases previously stored biogenic carbon back into the atmosphere. While there seems general agreement that carbon emitted from bioenergy combustion was and will again be sequestered from the atmosphere given a sustainable biomass management system, there is inherent concern that carbon release and sequestration rates may not be in temporal balance with each other and eventually jeopardize mid-century carbon/temperature/climate targets. So far, biomass carbon accounting systems (including those that are part of regulatory standards) have not incorporated this potential temporal imbalance or ';carbon debt'. The potential carbon debt caused by wood harvest and the resulting time spans needed to reach pre-harvest carbon levels (payback) or those of a reference case (parity) have become important parameters for climate and bioenergy policy developments. The present range of analyses however varies in assumptions, regional scopes, and conclusions. Policy makers are confronted with this portfolio while needing to address the temporal carbon aspect in current regulations. In order to define policies for our carbon constrained world, it is critical to better understand the dimensions and regional differences of these carbon cycles. This paper/presentation discusses to what extent and under which circumstances (i.e. bioenergy systems) a temporal forest carbon imbalance could jeopardize future temperature and eventually climate targets. It further reviews the current state of

    2016-06-01

    The aim of the article is to identify and analyse public-private incentives for the development and marketing of new animal vaccines within a real options methodological framework, and to investigate how real options methodology can be utilized to support economic incentives for vaccine development in a cost-effective way. The development of a vaccine against Campylobacter jejuni in poultry is applied as a case study. Employing the real options methodology, the net present value of the vaccine R&D project becomes larger than a purely probabilistic expected present value throughout the different stages of the project - and the net present value becomes larger, when more types of real options are taken into consideration. The insight from the real options analysis reveals opportunities for new policies to promote the development of animal vaccines. One such approach might be to develop schemes combining stage-by-stage optimized subsidies in the individual development stages, with proper account taken of investors'/developers' economic incentives to proceed, sell or cancel the project in the respective stages. Another way of using the real options approach to support the development of desirable animal vaccines could be to issue put options for the vaccine candidate, enabling vaccine developers to hedge against the economic risk from market volatility.

    Many countries rely on standard recipes for accelerating progress toward universal health coverage (UHC). With limited generalizable empirical evidence, expert confidence and consensus plays a major role in shaping country policy choices. This article presents an exploratory attempt conducted between April and September 2016 to measure confidence and consensus among a panel of global health experts in terms of the effectiveness and feasibility of a number of policy options commonly proposed for achieving UHC in low- and middle-income countries, such as fee exemptions for certain groups of people, ring-fenced domestic health budgets, and public-private partnerships. To ensure a relative homogeneity of contexts, we focused on French-speaking sub-Saharan Africa. We initially used the Delphi method to arrive at expert consensus, but since no consensus emerged after 2 rounds, we adjusted our approach to a statistical analysis of the results from our questionnaire by measuring the degree of consensus on each policy option through 100 (signifying total consensus) minus the size of the interquartile range of the individual scores. Seventeen global health experts from various backgrounds, but with at least 20 years' experience in the broad region, participated in the 2 rounds of the study. The results provide an initial "mapping" of the opinions of a group of experts and suggest interesting lessons. For the 18 policy options proposed, consensus emerged only on strengthening the supply of quality primary health care services (judged as being effective with a confidence score of 79 and consensus score of 90), and on fee exemptions for the poorest (judged as being fairly easy to implement with a confidence score of 66 and consensus score of 85). For none of the 18 common policy options was there consensus on both potential effectiveness and feasibility, with very diverging opinions concerning 5 policy options. The lack of confidence and consensus within the panel seems to

    We project the well-to-wheels (WTW) and tank-to-wheels (TTW) fossil-energy use, petroleum use, and greenhouse gas (GHG) emissions of the road-transport sector in China up to year 2050 and evaluate the effects of various potential policy options with the fuel economy and environmental impacts (FEEI) model ( (http://www.feeimodel.org/)). The policies evaluated include (1) vehicle fuel-consumption improvements, (2) dieselization, (3) vehicle electrification, and (4) fuel diversification, with plausible policy scenarios. Under the business-as-usual scenario, road transport in China would create 410–520 million metric tons (MMT) of oil-equivalent of TTW oil demand (three to four times the current level), 28–36 billion GJ of WTW energy demand, and 1900–2300 MMT of CO 2 -equivalent of WTW GHG emissions by 2050. The policies (in the same order as above) are projected to reduce the TTW oil demand by 35%, 10%, 29%, and 44%, and reduce WTW GHG emissions by 34%, 5%, 12%, and 13%, respectively, by 2050. This evaluation reveals that the fuel-consumption improvement policy could achieve greater benefit in reducing oil use, fossil-energy use, and GHG emissions. Implications of each policy option are discussed and the uncertainties associated with the policy scenarios are analyzed. - Highlights: ► Fuel-cycle energy use and GHG emissions of vehicles in China are projected up to 2050. ► Various policies are evaluated with the fuel economy and environmental impacts model. ► Fuel economy standards have greatest benefit in saving energy use and GHG emissions. ► Electrification is effective. Benefit of dieselization and fuel blending is limited.

    The international maritime transport sector has a significant abatement potential and some technical improvements that reduce GHG emissions would already be profitable without any policy in place. This paper analyses in-depth the limits and opportunities of policy options currently under consideration at the international level to stimulate the sector to reduce its GHG emissions. In particular, in order for the maritime transport sector to become more environmentally friendly, the flexible nature of international market-based measures and the European Union Emission Trading Scheme provide a definite window of opportunity without placing unnecessary high burden on the sector. However, the development of a regional policy, such as at European level, for the international maritime transport sector faces several obstacles: allocation of emissions, carbon leakage, permit allocation, treatment of the great variety in ship type, size and usage, and transaction cost. Global market-based policies could overcome most of these challenges. This paper provides an in-depth analysis of the policy instruments currently under discussion to reduce the sector's burden on the environment, and focuses on economic theory, legal principles, technological options, and the political framework that together make up the basis of decision-making regarding the international maritime transport sector's climate change policies. - Highlights: → Technologies for a more environmental friendly maritime transport sector and their cost-effectiveness. → How to combine ambitious CO 2 reduction goals with a sector-wide market-based policy. → Permits should be auctioned frequently and small emitters have to be excluded. → Inclusion of shipping in the EU ETS causes carbon leakage, so the policy should aim at expansion.

    The adverse relation between dietary trans fatty acid (TFA) intake and coronary artery disease risk is well established. Many countries in the European Union (EU) and worldwide have implemented different policies to reduce the TFA intake of their populations. The aim of this study was to assess the added value of EU-level action by estimating the cost-effectiveness of 3 possible EU-level policy measures to reduce population dietary TFA intake. This was calculated against a reference situation of not implementing any EU-level policy (i.e., by assuming only national or self-regulatory measures). We developed a mathematical model to compare different policy options at the EU level: 1) to do nothing beyond the current state (reference situation), 2) to impose mandatory TFA labeling of prepackaged foods, 3) to seek voluntary agreements toward further reducing industrially produced TFA (iTFA) content in foods, and 4) to impose a legislative limit for iTFA content in foods. The model indicated that to impose an EU-level legal limit or to make voluntary agreements may, over the course of a lifetime (85 y), avoid the loss of 3.73 and 2.19 million disability-adjusted life-years (DALYs), respectively, and save >51 and 23 billion euros when compared with the reference situation. Implementing mandatory TFA labeling can also avoid the loss of 0.98 million DALYs, but this option incurs more costs than it saves compared with the reference option. The model indicates that there is added value of an EU-level action, either via a legal limit or through voluntary agreements, with the legal limit option producing the highest additional health benefits. Introducing mandatory TFA labeling for the EU common market may provide some additional health benefits; however, this would likely not be a cost-effective strategy.

    The public perceives that the more we recycle, the better off we are. However, both the concept of recycling and the benefits to be achieved from recycling are somewhat vague. To determine the best option for disposition of a material at the end of its first use, we need to first define the available options and then clarify the possible goals that can be achieved by them. The best option will depend on the material, goals to be achieved, and location-dependent factors, such as costs, resources, and regulations. This paper presents the results of a life-cycle energy analysis of kraft paper and newsprint by Argonne National Laboratory. They indicate that under some circumstances, the option of fiber-energy recovery will maximize the benefits that can. be realized from the U.S. used paper resource.

    2013-01-01

    Highlights: • Assesses land management options after the Fukushima accident. • Builds a model for exploring intervention and decontaminations options in areas affected by radioactive contamination. • Findings suggest delaying decontamination efforts by 3–10 years is optimal with a central figure of 8.75 years. • Results are sensitive to estimates of the benefits of resettlement. • Poor state of knowledge about some variables that are key for policy actions, such as psychological benefits and costs of resettlement. -- Abstract: In the light of the Japanese government's intensive efforts to decontaminate areas affected by radioactive Caesium from Fukushima dai-ichi nuclear power plant, I create a framework for assessing the merits of management options. In particular I consider delayed intervention as a possible policy. Delay can be optimal because allowing the natural decay of radiation can lower significantly the costs of achieving targets for exposure. Using some benchmark data for Japan I estimate that optimal delay is positive for most reasonable parameter values. Optimal delay generally lies in the range of 3–10 years with a central figure of 8.8 years. There is however considerable uncertainty over some of the key parameter values, particularly with regard to the behaviour of currently evacuated inhabitants

    The World Health Organization recommends replacement of trans fat with polyunsaturated fat to reduce cardiovascular disease risk. Although several high-income countries have been successful in reducing trans fat in the food supply, low- and middle-income countries such as India may face additional contextual challenges such as the large informal sector, lack of consumer awareness, less enforcement capacity and low availability and affordability of healthier unsaturated fats. The objective of this study was to examine the feasibility and acceptability of multisectoral policy options aimed at supporting trans fat reduction and its replacement with polyunsaturated fats in India. Multisectoral policy options examined in this study were identified using food supply chain analysis. Semi-structured interviews (n = 17) were conducted with key informants from agriculture, trade, finance, retail, industry, food standards, non-governmental organizations and the health professions to gain their views on the feasibility and acceptability of the policy options. Purposive sampling was used to identify key informants. Data were coded and organized based on key themes. There was support for policies aimed at improving the quality of seeds, supporting farmer co-operatives and developing affordable farming equipment suited to smallholders to improve the production of healthier oils. Increasing the role of the private sector to improve links among producers, processors and retailers may help to streamline the fats supply chain in India. Blending healthier oils with oils high in saturated fat, which are currently readily available, could help to improve the quality of fat in the short term. Improving consumer awareness through mass media campaigns and improved labelling may help increase consumer demand for healthier products. Reorienting agricultural policies to support production of healthier oils will help increase their uptake by industry. Policy coherence across sectors will be

    U.S. environmental policy has a turbulent history. Although Americans strongly express themselves in favor of the preservation of the environment, elections do not always reflect this attitude. Thus, the policy of the seventies, which was based on strict environmental regulation, was followed by deregulation under Reagan. Environmental responsibility was shifted from the federal to the governmental level where economic interests tend to dominate and where financial means for the environment are insufficient. The environmental policy which has come on stronger in recent years is mainly based on market-oriented methods. Academic discussion about the preservation and improvement of the environment goes on and continues to bring forth different proposals. (orig.).

    AIM (Asian-Pacific Integrated Model) has been developed for predicting greenhouse gas emissions and evaluating policy measures to reduce them. Two socio-economic scenarios were assumed and CO 2 emissions were predicted based on these scenarios and policy intervention assumptions. It is found that mitigating CO 2 emissions without scaling back productive activities or standards of living in Japan is possible. However, if one relies on the market mechanism alone, it cannot be done. The analysis has shown that it is essential to introduce new policies and measures such as carbon tax and subsidies. (author)

    Ge, Jianping; Lei, Yalin

    2017-01-01

    The Chinese government has been issuing numerous incentive policies to promote non-grain bioethanol development to address the problem of excessive energy consumption and environmental pollution. In this study, we divide the incentive policies into five categories: subsidies on bioethanol production, non-grain feedstocks planting, marginal land reclamation and utilization, bioethanol consumption in more cities, and consumption tax on gasoline use. The objective of the paper is to evaluate and compare the economic, energy, and environmental effects of the incentive policies to help the government choose the optimal policies to promote bioethanol in China. The results show that subsidies on bioethanol production and consumption can boost GDP, and simultaneously, decrease crude oil and gasoline consumption, and reduce CO_2 emissions. However, the increase in bioethanol consumption is combined with the rise in coal and electricity consumption. Subsidies on bioethanol production can promote GDP and reduce energy consumption and CO_2 emission but have less effect on bioethanol development than that under the scenario of subsides on bioethanol consumption. On the contrary, although subsidies on non-grain feedstocks planting and marginal land reclamation and utilization can improve macro-economy but have a negative effect on energy saving and CO_2 emission reduction. Therefore, appropriate subsidies on bioethanol production and consumption can promote bioethanol consumption with economic, energy and environmental benefits. The Chinese government should further pay more attention to the coordination of different policy options by policy tools and intensities. - Highlights: • Non-grain bioethanol incentive policy is divided into supply and demand perspectives. • China's bioethanol CGE model is constructed. • Demand incentives have largest positive effects on GDP. • Demand incentives have better effects on energy saving and emission reduction. • Subsidies on

    To identify the behavioral mechanisms and effects of tobacco control policies designed to reduce tobacco retailer density. We developed the Tobacco Town agent-based simulation model to examine 4 types of retailer reduction policies: (1) random retailer reduction, (2) restriction by type of retailer, (3) limiting proximity of retailers to schools, and (4) limiting proximity of retailers to each other. The model examined the effects of these policies alone and in combination across 4 different types of towns, defined by 2 levels of population density (urban vs suburban) and 2 levels of income (higher vs lower). Model results indicated that reduction of retailer density has the potential to decrease accessibility of tobacco products by driving up search and purchase costs. Policy effects varied by town type: proximity policies worked better in dense, urban towns whereas retailer type and random retailer reduction worked better in less-dense, suburban settings. Comprehensive retailer density reduction policies have excellent potential to reduce the public health burden of tobacco use in communities.

    2011-01-01

    Repowering of a wind farm is the process of replacing existing wind turbines with new turbines that either have a larger nameplate capacity or more efficiency, resulting in a net increase of the power generated. Although repowering brings, both, social and private benefits, there are also several obstacles to repowering which justify public support. The aim of this paper is to provide an overview and a qualitative analysis of instruments and design options to support repowering of on-shore wind farms. The multicriteria analysis carried out in this paper shows that all instruments have their advantages and drawbacks. However, feed-in tariffs and investment subsidies seem to be particularly appropriate instruments in this regard. Furthermore, we provide an assessment of different design options to promote repowering according to key assessment criteria. The relevance of design elements hinges on the fact that these are the ones directly affecting the variables that are relevant in the decision to repower (capacity factors and investment costs). - Research highlights: → This paper provides a qualitative analysis of instruments and design options to support repowering in wind farms. → The multicriteria analysis has shown that all instruments have their advantages and drawbacks regarding promotion of repowering. → However, feed-in tariffs and investment subsidies seem to be particularly appropriate instruments in this regard. → The choice of design elements within instruments is at least as important to promote repowering as the choice of specific instruments.

    Climate change is a global challenge and one of biggest challenges of this century. Addressing the challenges posed by climate change requires new thinking in foreign policy. This paper discussed the results of a research study that examined the role of foreign policy in fostering a more effective international response to the challenge of climate change. The scope involved an examination of instruments relevant to Danish foreign policy. The paper first identified the climate change challenge and discussed international diplomacy and relations. Energy security and investment was discussed in terms of the impact of energy security on climate change efforts and opportunities for integration. Other areas where critical issues and opportunities for integration were offered include international peace and security; trade and investment; and development cooperation. The paper made several recommendations in these areas in addition to diplomatic networking. The study concluded that foreign policy can further the climate change agenda in a number of areas in diplomacy and foreign relations within the European Union, transatlantic relations, Arctic issues and United Nations affairs. This includes better integration of climate change into the European Union's common foreign and security policy, the Lisbon Agenda, and incorporating climate change in the work of a wide range of bodies under the United Nations. refs., figs

    2018-04-01

    Full Text Available The ecosystem services (ES approach offers an integrated perspective of social-ecological systems, suitable for holistic assessments of mining impacts. Yet for ES models to be policy-relevant, methodological consensus in mining contexts is needed. We review articles assessing ES in mining areas focusing on freshwater components and policy support potential. Twenty-six articles were analysed concerning (i methodological complexity (data types, number of parameters, processes and ecosystem–human integration level and (ii potential applicability for policy development (communication of uncertainties, scenario simulation, stakeholder participation and management recommendations. Articles illustrate mining impacts on ES through valuation exercises mostly. However, the lack of ground- and surface-water measurements, as well as insufficient representation of the connectivity among soil, water and humans, leave room for improvements. Inclusion of mining-specific environmental stressors models, increasing resolution of topographies, determination of baseline ES patterns and inclusion of multi-stakeholder perspectives are advantageous for policy support. We argue that achieving more holistic assessments exhorts practitioners to aim for high social-ecological connectivity using mechanistic models where possible and using inductive methods only where necessary. Due to data constraints, cause–effect networks might be the most feasible and best solution. Thus, a policy-oriented framework is proposed, in which data science is directed to environmental modelling for analysis of mining impacts on water ES.

In this paper, we analyze the causes of this gender discrimination in terms of institutions, culture and, economy, and suggest public policies that might help eliminate gender discrimination. Using a population simulation model, we study the effect of public policies on the sex ratio at birth and excess female child mortality, and the effect of gender discrimination on China's population development. We find that gender discrimination will decrease China's population size, number of births, and working age population, accelerate population aging and exacerbate the male marriage squeeze. These results provide theoretical support for suggesting that the government enact and implement public policies aimed at eliminating gender discrimination. PMID:24363477

Assessment of Policy Options to reducing air pollution from shipping'. Within this study it was decided to study the environmental impact of two legally possible trading systems: a voluntary emissions trading system for all sea areas belonging to the European Union and a mandatory emissions trading system for the ports and territorial waters of EU Member States. If the emissions in ports and coastal waters will be made part of such a trading system it can result in lower environmental exposure for the population.

Als de emissies in havens en kustwateren in een handelssysteem meedraaien, kan dat tot lagere blootstelling van de bevolking leiden.

  18. Evaluation of policy options to reform the EU Emissions Trading System. Effects on carbon price, emissions and the economy

    2013-04-15

    The EU Emissions Trading System (EU ETS) is a key instrument of EU climate policy, providing a clear reduction pathway for CO2 emissions. The current carbon price (of about 3 euros per tonne of CO2, April 2013) is much lower than previously expected (which was around 30 euros) and is likely to remain low for a long time. This fuels doubts about whether the ETS will remain a key policy instrument in the long term. Such doubts also increase investment uncertainty, which is likely to have a negative impact on further investments in low-carbon technologies needed for a low-carbon economy in 2050. In November 2012, the European Commission put forward six options for a more structural reform of the EU ETS. The proposed options vary from reducing the cap and expanding the ETS to include other sectors, to strengthening the ETS by measures directly affecting allowance prices. The Dutch Ministry of Infrastructure and the Environment (IenM) asked the PBL Netherlands Environmental Assessment Agency to assess the impact of these options. Four categories of options for reforming the ETS were evaluated: (1) reducing the supply of emission allowances; (2) expanding the ETS by including other sectors; (3) a minimum price for auctioned allowances; and (4) combining ETS with a carbon tax. Recently, the European Parliament voted against the European Commission's proposal to temporarily set aside emission allowances. In an earlier assessment of this proposal, PBL concluded that the impact of this backloading proposal on CO2 prices is likely to be limited, because the total amount of allowances up to 2020 would remain unchanged. All options analysed would reduce emissions and cause the emission price to increase. A minimum price on carbon, however, would provide the best opportunity to make the ETS more robust against unforeseen events, such as a further deterioration of the economy. Such a minimum price would result in more emission reductions if abatement proves to be cheaper

    In 2003 the May/June issue of CoalTrans International speculated that coal liquefaction would become viable due to falling coal prices. This has not proved the case but the sustained high oil price is sparking new interest. A survey by Energy Intelligence and Marketing Research during November 2005 revealed a growth in the number of projects under development or at the feasibility stage. The article reports projects in China, the USA, Australia, New Zealand, the Philippines and India. China is commissioning the first wave of large liquefaction plants. The key question is whether other countries, particularly the USA, will follow.

  1. Energy policy options--from the perspective of public attitudes and risk perceptions

    International Nuclear Information System (INIS)

    Viklund, Mattias

    2004-01-01

    In the present study a representative sample (N=797) of the Swedish population was surveyed, with regard to attitudes related to energy policy issues (e.g., environmental attitudes, risk perceptions, and attitudes towards different energy production systems), and self-reported electricity saving behavior. These factors were considered relevant in a Swedish energy policy context, due to the planned phase-out of nuclear power. Citizens' attitudes have traditionally been important factors in energy policy-making, especially nuclear policy. One of the conditions for a successful phase-out is decreased levels of electricity consumption among households and in industry, in order to compensate for the loss in energy production. Respondents reported positive attitudes to the environment in general and to electricity saving, while the attitudes to nuclear power as an energy production system in Sweden were relatively negative. Perceived risk was an important predictor of these attitudes and it was concluded that it is important to investigate factors behind this variable. The relationship between attitudes towards electricity saving and electricity saving behavior was weak. It is suggested that a contribution of psychological knowledge in energy conservation campaigns could be to elaborate on people's willingness to be public-spirited citizens in combination with their pro-environmental attitudes. Viklund (1999, Electricity saving: Attitudes and behavior of Swedish households. Center for Risk Research, Stockholm.) presented more data from the survey referred to here

    This research intends to explore possible design options for a sectoral approach in the cement sector in Shandong Province and to consider its respective advantages and disadvantages for future application. An effort has been made in this research to gather and analyze data that will provide a transparent and robust basis for development of a Business-As-Usual (BAU) scenario, maximum technology potential scenario, and ultimately a sector crediting baseline. Surveys among cement companies and discussions with stakeholders were also conducted in order to better understand the industry and local needs related to the sectoral approach.

  9. Greenhouse gas options, policy and measures for the Canadian Transportation Equipment Manufacturing Industry - Final report

    This report summarizes and analyses the work that have been carried out by the Transportation Equipment Manufacturing Sector (TEMS) Working Group of the National Climate Change Industry Table over the last 14 months, and presents the Group's view of appropriate policies for greenhouse gas emission reduction in Canada. To develop its approach, the Working Group conducted five separate studies which are included in this report as annexes. Annex A is a Foundation Paper, which provides an overview of the sector's performance vis-a-vis energy use and greenhouse gas production. Annex B analyzes the competitive position of the industry by reviewing growth trends in each of the industry sub-sectors and the key factors in maintaining and enhancing the sector's international competitive position. Annex C is a technology assessment. It provides an overview of the uptake of energy saving technology in the sector. Annex D provides a facility level analysis focusing on energy use in the automotive parts manufacturing sector. Annex E is a review of American policies on climate change, summarizing the approach currently being taken towards greenhouse gas emission reduction in the United States. Some of the key findings of this report are: (1) business-as-usual emissions will greatly exceed the implicit Kyoto target of six per cent reduction from 1990 levels, (2) relatively few opportunities exist for major emissions reductions through the use of existing technology, (3) sector-specific policies appear to be ill-advised, but cross-cutting policies provide good opportunities for the transportation equipment manufacturing sector to do its part in helping Canada meeting its Kyoto commitment. The report recommends investigation of barriers to adoption of new technologies and examination of market imperfections, promotion of cogeneration where it makes economic sense, and consideration of the use of flexible instruments such as carbon taxes and tradable emission permits.

    Indian agriculture is trapped in a complex nexus of groundwater depletion and energy subsidies. This nexus is the product of past public policy choices that initially offered opportunities to India's small-holder-based irrigation economy but has now generated in its wake myriad economic, social, and environmental distortions. Conventional `getting-the-price-right' solutions to reduce these distortions have consistently been undermined by the invidious political economy that the nexus has created. The historical evolution of the nexus is outlined, the nature and scale of the distortions it has created are explored, and alternative approaches which Indian policy makers can use to limit, if not eliminate, the damaging impacts of the distortions, are analysed.

  11. Energy in transition: a report on energy policy and future options

    Energy Technology Data Exchange (ETDEWEB)

    Loennroth, M; Steen, P; Johansson, T B

    1977-01-01

    This publication sums up reports published to create a conceptual background for analyzing Swedish long-term energy policy. Swedish energy policy--today, yesterday, tomorrow--is discussed in Chapter 1. Oil being supplemented now and replaced later is discussed in Chapter 2. Chapter 3 identifies the main alternatives: breeder reactors, coal, and renewable energy sources, i.e., solar energy. The alternatives possess varying characteristics and the supply of energy from these sources must fit into the pattern of energy use. Because of long lead times for development, Chapter 4 discusses the risks of getting rigidly committed and the chances of maintaining and creating freedom of action, so that none of the alternatives disappears unintentionally. Freedom of action has its limits, which mainly lie on three levels: the interaction of energy policy with other political goals; technical properties of the energy system; and characteristics of the economic and social system of rules in which the energy issues are to be found. Some conceivable conflicts over political goals are discussed in chapter 5, which takes up the relations between energy consumption on the one hand and, on the other hand, economic growth, environmental protection, geographic structure, foreign policy, etc. Technical limits to freedom of action are the subject of Chapter 6, which is chiefly concerned with the importance of energy quality and the energy carriers. Organizational and institutional limits to freedom of action are discussed in Chapter 7, taking as example the development of the electric sector in Sweden. The main conclusions are given in Chapter 8. (MCW)

    Gan Lin; Yu Juan

    2008-01-01

    This paper reviews the current situation of bioenergy development in China, particularly on its relationship to sustainable rural development. It argues that the current government strategy, investment policy and industrial interest are over-emphasized on biomass-burning power generation as part of the clean energy development trajectories, which may not lead to the most cost-effective outcomes in terms of investments, resource use and social development objectives. It points out that there are large potentials in developing and disseminating household-based biomass technologies in rural areas, especially with energy-efficient modern biomass stoves, which can produce far more economic, social and environmental benefits than biomass power plants. It is a decentralized solution to use renewable energy resources for meeting multi-objectives. It is suggested that key incentive policies be provided by the government to encourage this technological transition, or the leapfrogging from using traditional household stoves towards modern biomass stoves, which will lead to a win-win situation in global, regional and local environmental protection, sustainable resource management and related social benefits, particularly for the poor in remote communities. Six policy recommendations are made: (1) financial schemes development; (2) preferable tax and carbon tax; (3) regulatory policy reform; (4) service industry support; (5) market research, training and capacity building for key stakeholders; (6) development of methodologies and standards for CDM projects. The potential co-benefits brought up by this massive biomass technology transition will bring new perspectives to realizing Millennium Development Goals (MDGs) and global CO 2 emissions reduction targets in China, and also set an example to other developing countries

  15. Cost and CO2 aspects of future vehicle options in Europe under new energy policy scenarios

    International Nuclear Information System (INIS)

    Thiel, Christian; Perujo, Adolfo; Mercier, Arnaud

    2010-01-01

    New electrified vehicle concepts are about to enter the market in Europe. The expected gains in environmental performance for these new vehicle types are associated with higher technology costs. In parallel, the fuel efficiency of internal combustion engine vehicles and hybrids is continuously improved, which in turn advances their environmental performance but also leads to additional technology costs versus today's vehicles. The present study compares the well-to-wheel CO 2 emissions, costs and CO 2 abatement costs of generic European cars, including a gasoline vehicle, diesel vehicle, gasoline hybrid, diesel hybrid, plug in hybrid and battery electric vehicle. The predictive comparison is done for the snapshots 2010, 2020 and 2030 under a new energy policy scenario for Europe. The results of the study show clearly that the electrification of vehicles offer significant possibilities to reduce specific CO 2 emissions in road transport, when supported by adequate policies to decarbonise the electricity generation. Additional technology costs for electrified vehicle types are an issue in the beginning, but can go down to enable payback periods of less than 5 years and very competitive CO 2 abatement costs, provided that market barriers can be overcome through targeted policy support that mainly addresses their initial cost penalty.

  16. Policy options for the split incentive: Increasing energy efficiency for low-income renters

    International Nuclear Information System (INIS)

    Bird, Stephen; Hernández, Diana

    2012-01-01

    The split incentive problem concerns the lack of appropriate incentives to implement energy efficiency measures. In particular, low income tenants face a phenomenon of energy poverty in which they allocate significantly more of their household income to energy expenditures than other renters. This problem is substantial, affecting 1.89% of all United States' energy use. If effectively addressed, it would create a range of savings between 4 and 11 billion dollars per year for many of the nation's poorest residents. We argue that a carefully designed program of incentives for participants (including landlords) in conjunction with a unique type of utility-managed on-bill financing mechanism has significant potential to solve many of the complications. We focus on three kinds of split incentives, five concerns inherent to addressing split incentive problems (scale, endurance, incentives, savings, political disfavor), and provide a detailed policy proposal designed to surpass those problems, with a particular focus on low-income tenants in a U.S. context. - Highlights: ► We demonstrate the significant impact of the split incentive on low-income tenants. ► We discuss split incentive characteristics, and policy failures. ► We described an on-bill financing model with unique features. ► This policy has protections and incentives for tenants and landlords.

    This report provides an outline of the technical feasibility of the Dutch target of 20% biofuels on energy basis in 2020. In order to reach this target additional effort is required with respect to the obligatory market share of 10% as proposed by the EU. The first chapters of this report describe the basic data. Chapter 2 gives an overview of developments in the market for transport fuels in the period 2008-2020 and the division of that market in a number of market segments. Chapter 3 provides information on production, distribution, availability of vehicles and user aspects of the main biofuels. Subsequently, chapter 4 addresses the options for achieving the 20% biofuels target. Chapter 5 sketches the variants on the basic route and calculates the costs of these variants. Chapter 6 discusses the timing and cost of the basic route and the variants. The main conclusion of this report is that 20% blending can be achieved. [mk] [nl

  18. Who Owns Renewable Energy Certificates? An Exploration of PolicyOptions and Practice

    Energy Technology Data Exchange (ETDEWEB)

    Holt, Edward A.; Wiser, Ryan; Bolinger, Mark

    2006-04-05

    Renewable energy certificates (RECs) represent the bundle of information that describes the characteristics of renewable electricity generation, and may be (and increasingly are) sold separately from the underlying electricity itself. RECs are a relatively new phenomenon, emerging as a tradable commodity in voluntary markets in the late 1990s, and gaining strength as a means of compliance with various state policy requirements affecting renewable generation in the early 2000s (Holt and Bird 2005). Twenty states and Washington, D.C. now have mandatory renewables portfolio standard (RPS) obligations, and most of these may be satisfied by owning and retiring RECs. Many states also have fuel source and emissions disclosure requirements, for which RECs are useful. Even where state policy does not allow unbundled and fully tradable RECs to meet these requirements, RECs may still be used as an accounting and verification tool (REC tracking systems are in place or under development in many regions of the U.S.). These applications, plus REC trading activity in support of voluntary green claims, give rise to potential ''double counting'' to the extent that the purchaser of the RECs and the purchaser of the underlying electricity both make claims to the renewable energy attributes of the facility in question (Hamrin and Wingate 2003). When renewable electricity is sold and purchased, an important question therefore arises: ''Who owns the RECs created by the generation of renewable energy?'' In voluntary transactions, most agree that the question of REC ownership can and should be negotiated between the buyer and the seller privately, and should be clearly established by contract. Claims about purchasing renewable energy should only be made if REC ownership can be documented. In many other cases, however, renewable energy transactions are either mandated or encouraged through state or federal policy. In these cases, the issue of REC

    Objectives Regional centres and their rural hinterlands support significant populations of non-metropolitan Australians. Despite their importance in the settlement hierarchy and the key medical services provided from these centres, little research has focused on their issues of workforce supply and long-term service requirements. In addition, they are a critical component of the recent growth of 'regional' hub-and-spoke specialist models of service delivery. Methods The present study interviewed 62 resident specialists in four regional centres, seeking to explore recruitment and retention factors important to their location decision making. The findings were used to develop a framework of possible evidence-informed policies. Results This article identifies key professional, social and locational factors, several of which are modifiable and amenable to policy redesign, including work variety, workplace culture, sense of community and spousal employment; these factors that can be targeted through initiatives in selection, training and incentives. Conclusions Commonwealth, state and local governments in collaboration with communities and specialist colleges can work synergistically, with a multiplicity of interdigitating strategies, to ensure a positive approach to the maintenance of a critical mass of long-term rural specialists. What is known about the topic? Rural origin increases likelihood of long-term retention to rural locations, with rural clinical school training associated with increased rural intent. Recruitment and retention policy has been directed at general practitioners in rural communities, with little focus on regional centres or medical specialists. What does this study add? Rural origin is associated with regional centre recruitment. Professional, social and locational factors are all moderately important in both recruitment and retention. Specialist medical training for regional centres ideally requires both generalist and subspecialist skills

    1979-01-01

    This study provides a discussion of the origins and evolution of US strategic nuclear policy, the objectives an requirements of US nuclear forces, and an assessment of present and emerging US stategic nuclear policy and force structure options. It identifies the distinctive phases of US strategic nuclear policy, the conditions of the military environments in which those policies were developed, the interaction of US-Soviet strategic force and arms control processes during these phases, and the domestic debates which have accompanied US strategic nuclear policy developments. In particular, the study focuses on the major contending views which continue to characterize the debate concerning US strategic nuclear policy. The study assesses the implications of the contending views represented in what is commonly referred to as the counterforce-countervalue debate, particularly as they relate to the perception of what constitutes a credible US deterrent posture, and the corresponding alternatives that these views bring with them for making US strategic nuclear policy and force structure decisions. The arms control process, in general, and SALT I and SALT II in particular, is discussed as an integral and dynamic component of the strategic debate, fundamentally affecting the nation's security policies. The implications of modern weapons technology, and the problems inherent in preserving strategic stability between adversary nations with asymmetries in military force structures and doctrines, are also discussed. Further, the study focuses on the question of whether or not nuclear superiority can be considered relevant under the contemporary international conditions

    This study analyze the potential factors influencing the growth of transport sector carbon dioxide (CO 2 ) emissions in selected Asian countries during the 1980-2005 period by decomposing annual emissions growth into components representing changes in fuel mix, modal shift, per capita gross domestic product (GDP) and population, as well as changes in emission coefficients and transportation energy intensity. We find that changes in per capita GDP, population growth and transportation energy intensity are the main factors driving transport sector CO 2 emission growth in the countries considered. While growth in per capita income and population are responsible for the increasing trend of transport sector CO 2 emissions in China, India, Indonesia, Republic of Korea, Malaysia, Pakistan, Sri Lanka and Thailand; the decline of transportation energy intensity is driving CO 2 emissions down in Mongolia. Per capita GDP, population and transportation energy intensity effects are all found responsible for transport sector CO 2 emissions growth in Bangladesh, the Philippines and Vietnam. The study also reviews existing government policies to limit CO 2 emissions growth, such as fiscal instruments, fuel economy standards and policies to encourage switching to less emission intensive fuels and transportation modes.

    To determine obstacles/opportunities within policy processes, for smokefree interventions appropriate to Maori. In particular, to explore Maori policymakers' ideas on how to achieve progress on smokefree homes, cars and community property. Documents and interviews with 16 senior Maori officials and Members of Parliament, and nine interviews in two case studies, were used to explore Maori policymakers' ideas for (i) Progress, within relevant policy processes, on smoking in homes, cars and community property; (ii) Particular interventions that the interviewees felt were most and least effective, practical, sustainable, politically feasible or desirable in some way; (iii) The context, and obstacles and opportunities for such interventions. The case studies were of a Maori health service and a group of Maori District Health Board managers. Several key themes emerged from the research including, (i) children as drivers for change, (ii) strong national and local indigenous leadership needed for change, (iii) delivering smokefree messages as part of wider healthy living approaches, (iv) targeting of the messages for greatest impact for Maori, (v) need for a Maori approach, not a general approach, (vi) central and local government having a significant role in the prevention of tobacco harm, (vii) ideas on how tobacco tax revenue should be spent on tobacco control, and (viii) the rights of children to smokefree environments. Results indicate that indigenous specific approaches and indigenous leadership are critical for Maori tobacco-free advances. Harnessing indigenous values and principles related to health, family and children was the preferred method of these Maori policymakers for delivering social marketing messages.

    Uncertainty surrounds the choice of instruments that internalise fossil-fuel pollution at the local, regional and global level. This work outlines the considerable growth in the Western Australian (WA) energy sector and explores the available options and potential hazards of using specific instruments to internalise externalities. These core options are discussed with respect to liberalising energy markets, providing private investment certainty, and imparting commentary on the developments and consequences of reform in the WA context. As a large energy exporter, providing certainty for the WA energy sector investment and the community is necessary to maintain the current prosperity. Remarkably, in the decades of market reform progress, the absence of one essential element is evident: economic externalities. Policymakers are under increasing pressure to understand economic reform, new energy markets and the multifaceted repercussions they entail. With modern energy reform sitting squarely within the milieu of more efficient governments and climate policy, there are clear economic advantages to internalising negative and positive externalities and other market distortions during energy market developments. Ignoring market failures when commercialising government-owned energy utilities in de-regulated and competitive markets invites continued ad-hoc government interference that generates investment uncertainty in addition to a perplexed electorate.

    The Harvard University Center for the Environment and partner institutions in China established a multidisciplinary program of integrated research on energy-related environmental issues, local air pollution and global climate change, in China and their role in U.S.-Chinese relations. Major research streams included: (a) developing a dynamic, multi-sector model of the Chinese economy that can estimate energy use, emission, and health damages from pollution, and using this model to simulate broad economic effects of market-based pollution-control policies; (b) developing a regionally disaggregated model of technology and investment choice in the Chinese electric power sector; (c) applying an atmospheric chemical tracer transport model to investigate carbon uptake in Eurasis (notably China) and North America, and to inform observational strategies for CO{sub 2} in China and elsewhere.

    Radiologists today are faced with the challenges of maintaining and balancing individual and family health needs and the demands of the workplace. To provide the highest quality and safest care of our patients, a corresponding ethos of support for a healthy workforce is required. There is a paucity of targeted information describing protections for and maintenance of the health of the practicing radiologist, in both private and academic settings. However, a review of existing family and medical leave policies may be helpful to practice leaders and practicing radiologists as a platform for the development of strategic workforce plans. This writing, by members of the ACR Commission on Human Resources, addresses the following areas: (1) medical leave, (2) maternity and/or paternity leave, and (3) disability.

    2011-01-01

    The international community inside and outside the Conference of Disarmament is underscoring the need for concluding a fissile material cut-off treaty (FMCT). The Indian government, for a long period, has been sponsoring the idea. Notwithstanding the international stagnation, the issue has been instigating periodic debate in India on the Indian approach. The periodic revival of the issue requires that India revisit its policy on fissile material production as well as its approach towards a possible EVICT. This article examines the question: should India's approach to conclude an FMCT be within the UN institutional framework? The new international reality is pushing for a new context, new realignments and a fresh outlook for an FMCT. India should take its own time to support conclusion of an FMCT so that its national interests and security are not adversely affected. (author)

    The EU has set emission targets for new cars up to 2020 and is now preparing the post 2020 legislation. The present study aims to give insight in the design of policies to further reduce passenger car emissions after 2020. Internal combustion engine (ICE) vehicles are now expected to enable deeper and less costly CO2 emission reductions than envisioned until recently. However, even advanced ICE vehicles will not enable to meet the very stringent long term emission reduction targets for passenger cars. Therefore transport policies need not only to reduce emissions of ICE vehicles, but also ensure that electric and hydrogen vehicles are phased in timely, along with low-CO2 electricity and hydrogen. Current legislation to regulate tank-to-wheel vehicle emissions is based on CO2-limits, expressed in g CO2/km. On the short term it is important to maximize the efficiency of conventional vehicles. At the same time it is essential to foster the market introduction of electric and hydrogen vehicles, given their potential to reach eventually much deeper overall CO2-reductions. When the market share of electric and hydrogen vehicles grows it becomes increasingly important to maximize their efficiency and to minimize their upstream CO2 emissions. Maximizing both efficiency and overall CO2-performance of all vehicle types - ICE, electric, and hydrogen - will be complicated to achieve with a single CO2-based standard. At this point an efficiency-based standard is more effective, and may offer some additional benefits too. The current report provides basic directions of how such legislation could be shaped.

  15. Private initiatives and policy options: recent health system experience in India.

    In the recent past the impact of structural adjustment in the Indian health care sector has been felt in the reduction in central grants to States for public health and disease control programmes. This falling share of central grants has had a more pronounced impact on the poorer states, which have found it more difficult to raise local resources to compensate for this loss of revenue. With the continued pace of reforms, the likelihood of increasing State expenditure on the health care sector is limited in the future. As a result, a number of notable trends are appearing in the Indian health care sector. These include an increasing investment by non-resident Indians (NRIs) in the hospital industry, leading to a spurt in corporatization in the States of their original domicile and an increasing participation by multinational companies in diagnostics aiming to capture the potential of the Indian health insurance market. The policy responses to these private initiatives are reflected in measures comprising strategies to attract private sector participation and management inputs into primary health care centres (PHCs), privatization or semi-privatization of public health facilities such as non-clinical services in public hospitals, innovating ways to finance public health facilities through non-budgetary measures, and tax incentives by the State governments to encourage private sector investment in the health sector. Bearing in mind the vital importance of such market forces and policy responses in shaping the future health care scenario in India, this paper examines in detail both of these aspects and their implications for the Indian health care sector. The analysis indicates that despite the promising newly emerging atmosphere, there are limits to market forces; appropriate refinement in the role of government should be attempted to avoid undesirable consequences of rising costs, increasing inequity and consumer exploitation. This may require opening the health

    2011-01-01

    U.S. ethanol policies have contributed to changes in the levels and the volatilities of revenues and costs facing ethanol firms. The implications of these policies for optimal investment behavior are investigated through an extension of the real options framework that allows for the consideration of volatility in both revenue and cost components, as well as the correlation between them. The effects of policy affecting plant revenues dominate the effects of those policies affecting production costs. In the absence of these policies, much of the recent expansionary periods would have not existed and market conditions in the late-1990s would have led to some plant closures. We also show that, regardless of plant size, U.S. ethanol policy has narrowed the distance between the optimal entry and exit curves, implying a more narrow range of inactivity and indicative of a more volatile evolution for the industry than would have existed otherwise. - Highlights: ► An extended real options framework with two stochastic variables is developed. ► Ethanol expansion largely induced by the revenue-enhancing effects of policy. ► Removing effects of policy changes optimal entry/exit environment considerably. ► To expand US ethanol industry, size of policy contributions needs to grow. ► US ethanol policy has fostered more volatile industry development.

    The developing countries of Asia are amongst the largest contributors to the anthropogenic emissions of greenhouse gases as well as being amongst those most likely to be impacted by global climate change. There are at present no legal requirements for the Asian developing countries to reduce their emissions, however, the medium and long-term impact of global climate change is likely to be proportionately larger for the developing countries than for the industrialized countries, since the latter have the resources to reduce the adverse impacts. Therefore, it is of great interest of the developing countries, as well as the rest of the world, to have longer-term goals for stabilizing their greenhouse gas emissions, and taking actions during the medium term to achieve these goals. Asia is home to about 50% of the world's population, and there is great variation in the levels of industrialization and contribution to greenhouse gas emissions. A differentiated strategy for addressing concerns related to global climate change may be appropriate for the Asian developing countries at this time. Some elements of this strategy are discussed in this paper. Development in energy technology present several attractive options for the developing countries. However, their introduction and successful use depends at least as much on the existence of the necessary infrastructure as on the attractiveness of the technologies themselves. It is suggested that international and bilateral development agencies, as well as the countries themselves, consider the accelerated development of such infrastructure as a major way to contribute to the efforts to address global climate change.

    2009-01-01

    Research shows that livestock account for a significant proportion of greenhouse gas (GHG) emissions and global consumption of livestock products is growing rapidly. This paper reviews the life cycle analysis (LCA) approach to quantifying these emissions and argues that, given the dynamic complexity of our food system, it offers a limited understanding of livestock's GHG impacts. It is argued that LCA's conclusions need rather to be considered within a broader conceptual framework that incorporates three key additional perspectives. The first is an understanding of the indirect second order effects of livestock production on land use change and associated CO 2 emissions. The second compares the opportunity cost of using land and resources to rear animals with their use for other food or non-food purposes. The third perspective is need-the paper considers how far people need livestock products at all. These perspectives are used as lenses through which to explore both the impacts of livestock production and the mitigation approaches that are being proposed. The discussion is then broadened to consider whether it is possible to substantially reduce livestock emissions through technological measures alone, or whether reductions in livestock consumption will additionally be required. The paper argues for policy strategies that explicitly combine GHG mitigation with measures to improve food security and concludes with suggestions for further research.

    With the aim of promoting institutional births and reducing the high maternal and child mortality rates in rural and poor zones, the government of Nicaragua is supporting the creation of maternity waiting homes. This study analyzes that strategy and examines the factors associated with the use of maternity waiting homes and institutional birth. To that end, we apply a quantitative approach, by means of an econometric analysis of the data extracted from surveys conducted in 2006 on a sample of women and parteras or traditional birth attendants, as well as a qualitative approach based on interviews with key informants. Results indicate that although the operation of the maternity waiting homes is usually satisfactory, there is still room for improvement along the following lines: (i) disseminating information about the homes to both women and men, as the latter frequently decide the course of women's healthcare, and to parteras, who can play an important role in referring women; (ii) strengthening the postpartum care; (iii) ensuring financial sustainability by obtaining regular financial support from the government to complement contributions from the community; and (iv) strengthening the local management and involvement of the regional government. These measures might be useful for health policy makers in Nicaragua and in other developing countries that are considering this strategy. Copyright © 2011 John Wiley & Sons, Ltd.

    Full Text Available An important challenge of the environmental policy is conceivingappropriate economic instruments able to account for the positive externalities provided by forest ecosystems. This issue is extremely important for implementing the provisions of the Romanian Forest Act, which states that forest owners shall be compensated for the opportunity costs of giving up harvesting operations due to various conservation purposes. The paper presents a statistical method based on analytical assessment of the effective forgone revenues brought about by banning the harvesting operations in 96 cases, each case being a distinctive forest management plan conceived for a large forest area, i.e. a production unit. Doing so, the scale effect has been taken into account because all legal provisions referring to forest management planning systems are focused on production units, considered the basic reference elements for sustainable forest management. The multiple regression function produced by the statistical analysis was turned into a simple formula allowing for a straightforward set up of the average compensation worth being paid per year and hectare. In order to better fetch the real opportunity cost paid for each hectare of protected forest, the algorithmwas further improved in order to account for the differences in stumpage residual value. Actually, the average compensation is differentiated onto five categories of hauling distances, using the same algorithm used by the National Forest Administration for differentiating the average reservation price established at national level on the ground of full-cost method stumpage pricing system.

  5. Managing vulnerability to drought and enhancing livelihood resilience in sub-Saharan Africa: Technological, institutional and policy options

    Full Text Available Agriculture and the economies of Sub-Saharan Africa (SSA are highly sensitive to climatic variability. Drought, in particular, represents one of the most important natural factors contributing to malnutrition and famine in many parts of the region. The overall impact of drought on a given country/region and its ability to recover from the resulting social, economic and environmental impacts depends on several factors. The economic, social and environmental impacts of drought are huge in SSA and the national costs and losses incurred threaten to undermine the wider economic and development gains made in the last few decades in the region. There is an urgent need to reduce the vulnerability of countries to climate variability and to the threats posed by climate change. This paper attempts to highlight the challenges of drought in SSA and reviews the current drought risk management strategies, especially the promising technological and policy options for managing drought risks to protect livelihoods and reduce vulnerability. The review suggests the possibilities of several ex ante and ex post drought management strategies in SSA although their effectiveness depends on agro-climatic and socio-economic conditions. Existing technological, policy and institutional risk management measures need to be strengthened and integrated to manage drought ex ante and to minimize the ex post negative effects for vulnerable households and regions. A proactive approach that combines promising technological, institutional and policy solutions to manage the risks within vulnerable communities implemented by institutions operating at different levels (community, sub-national, and national is considered to be the way forward for managing drought and climate variability.

  8. Residential Water Scarcity in Cyprus: Impact of Climate Change and Policy Options

    Full Text Available This paper presents an assessment of the cost of water scarcity in Cyprus, today and in the next 20 years, taking into account the effect of projected climate change in the region. It focuses on the residential sector, accounting also for tourism and industry. Using a simple demand function, total scarcity costs in Cyprus are computed for the period 2010–2030, and three scenarios of future water demand are presented. The central estimate shows that the present value of total costs due to water shortages will amount to 72 million Euros (at 2009 prices, and, if future water demand increases a little faster, these costs may reach 200 million Euros. Using forecasts of regional climate models, costs are found to be about 20% higher in a “climate change” scenario. Compared to the loss of consumer surplus due to water shortages, desalination is found to be a costly solution, even if environmental damage costs from the operation of desalination plants are not accounted for. Finally, dynamic constrained optimization is employed and shows that efficient residential water prices should include a scarcity price of about 40 Eurocents per cubic meter at  2009 prices; this would constitute a 30–100% increase in current prices faced by residential consumers. Reductions in rainfall due to climate change would raise this price by another 2-3 Eurocents. Such a pricing policy would provide a clear long-term signal to consumers and firms and could substantially contribute to a sustainable use of water resources in the island.

    Between 2011 and 2013, global and national guidelines for preventing mother-to-child transmission (PMTCT) of HIV shifted to recommend Option B+, the provision of lifelong antiretroviral treatment for all HIV-infected pregnant women. We aimed to analyse how Option B+ reached the policy agenda, and unpack the processes, actors and politics that explain its adoption, with a focus on examining UNICEF's contribution to these events. Analysis drew on published articles and other documentation, 30 key informants interviews with staff at UNICEF, partner organisations and government officials, and country case studies. Cameroon, India, South Africa and Zimbabwe were each visited for 5-8 days. Interview transcripts were analysed using Dedoose software, reviewed several times and then coded thematically. A national policy initiative in Malawi in 2011, in which the country adopted Option B+, rather than existing WHO recommended regimens, irrevocably placed the policy on the global agenda. UNICEF and other organisations recognised the policy's potential impact and strategically crafted arguments to support it, framing these around operational considerations, cost-effectiveness and values. As 'policy entrepreneurs', these organisations vigorously promoted the policy through a variety of channels and means, overcoming concerted opposition. WHO, on the basis of scanty evidence, released a series of documents towards the policy's endorsement, paving the way for its widespread adoption. National-level policy transformation was rapid and definitive, distinct from previous incremental policy processes. Many organisations, including UNICEF, facilitated these changes in country, acting individually, or in concert. The adoption of the Option B+ policy marked a departure from established processes for PMTCT policy formulation which had been led by WHO with the support of technical experts, and in which recommendations were developed following shifts in evidence. Rather, changes were

  12. An Overview of Turkish Healthcare System after Health Transformation Program: Main Successes, Performance Assessment, Further Challenges, and Policy Options

    Full Text Available Turkish healthcare system has been stated to show significant improvements regarding wider access to healthcare facilities, and the quality and efficiency through the introduction of Health Transformation Program launched in 2003. While the old system relied on differing provisions and financing and lacked behind many developed nations in terms of health outcomes, the new system achieved nearly universal coverage and many health outcomes enhanced significantly. Health expenditures rose to 5.4% of GDP in 2013 from 4.8% in 1998. Furthermore, Turkey provided both better financial protection for the poor against high health expenditures, and equity in access to health care across the population. However, Turkey still faces new challenges to catch other developed countries to have better health and further improve financial sustainability. To reach these targets, Turkey needs to further implement new policy options for reform such as combating informal economy, allocating more on health resources, designing incentive- based payment methods, adopting gate keeping system and referral chain, developing capacity to deploy health technology assessments in reimbursement decisions, and ensuring the hospital autonomy.

    Effects of future expansion/intensification of irrigated agriculture on groundwater and surface water levels and availability in a semi-arid watershed were evaluated using an integrated hydrologic model (MIKE SHE/MIKE 11) in conjunction with biophysical measurements. Improved water use efficiency, water storage, and energy policy options were evaluated for their ability to sustain the future (2035) increased groundwater withdrawals. Three future withdrawal scenarios (low = 20, medium = 30, high = 50 wells/100 km2/year) based on the historical rate of growth of irrigation wells were formulated. While well drying from falling groundwater levels was limited to drought and consecutive below average rainfall years, under the current (2015) withdrawals, significant increases in frequency and duration (17-97 days/year) of well drying along with 13-26% (19-37 mm) reductions in surface flows were predicted under the future withdrawals. Higher (27-108%) energy demands of existing irrigation pumps due to declining groundwater levels and reduced hydroelectric generation due to decreased surface flows would create a vicious water-food-energy nexus in the future. Crop failure, one of the main causes of farmers' emotional distress and death in the region, is predicted to exacerbate under the future withdrawal scenarios. Shift to negative net recharge (-63 mm) and early and prolonged drying of wells under the high scenario will reduce the groundwater availability and negatively affect crop production in more than 60% and 90% of cropped areas in the Rabi (November-February) and summer (March-May) seasons, respectively during a drought year. Individual and combined demand (drip irrigation and reduced farm electricity subsidy) and supply (water storage) management options improved groundwater levels and reduced well drying by 55-97 days/year compared to business-as-usual management under the high scenario. The combined management (50% drip conversion, 50% reduction in subsidy, and

  14. Low-level radioactive waste disposal in the USA - Use of mill tailings impoundments as a new policy option

    2006-01-01

    Disposal of low-level radioactive waste (LLW) in the United States is facing severe and immediate capacity limitations. Seemingly intractable regulatory and jurisdictional conflicts make establishment of new LLW disposal sites effectively impossible. Uranium mill tailings impoundments constructed at conventional uranium open-cast and underground mines could offer approximately 40 to 80+ million tons of disposal capacity for low activity radioactive waste. Such impoundments would provide an enhanced, high level of environmental and health and safety protection for the direct disposal of depleted uranium, special nuclear material, technologically-enhanced, naturally-occurring radioactive material (TENORM) and mixed waste. Many waste streams, such as TENORM and decommissioning rubble, will be high-volume, low activity materials and ideally suited for disposal in such structures. Materials in a given decay chain with a total activity from all radionuclides present of ∼820 Bq/g (2.22 x 10 -08 Ci/g) with no single radionuclide present in an activity greater than ∼104 Bq/g (2,800 pCi/g) should be acceptable for disposal. Materials of this type could be accepted without any site-specific dose modelling, so long as the total activity of the tailings impoundment not exceed its design capacity (generally 82 x 10 07 Bq/metric tonne) (0.020 Ci/short ton) and the cover design requirements to limit radon releases are satisfied. This paper provides background on US LLW disposal regulations, examines LLW disposal options under active consideration by the US Environmental Protection Agency and Department of Energy, develops generic waste acceptance criteria and identifies policy needs for federal and state governments to facilitate use of uranium mill tailings impoundments for LLW disposal.

  19. Introducing short term flexibility in the EU ETS to assure its long-term credibility: a multi-criteria analysis of policy options. Climate Report no. 45

    Desai, Zuheir; Alberola, Emilie; Berghmans, Nicolas

    2014-07-01

    It is now well established that the European Union Emissions Trading Scheme (EU ETS) needs to be reformed. After more than 18 months of discussions, the EU Commission disclosed, in its communication published in January 2014 on 'A policy framework for climate and energy in the period from 2020 to 2030', its legislative proposal of a market stability reserve (MSR) in the EU ETS. This measure, that should be implemented from the next compliance period (2021-2028) onwards, would reduce the surplus of allowances growing since 2008 and improve the ETS's resilience to external shocks by automatically adjusting the supply of allowances to be auctioned. The operation of this MSR would be determined by predefined rules that, once agreed on, leave no discretion to either the Commission or Member States. The choice of the EU Commission to introduce a reserve in the EU ETS is very innovative even if other emissions trading schemes have already introduced a reserve in their design. Initial discussions began in March and April 2014 in the European Parliament and Council and the question of whether the MSR really improves the functioning of the EU ETS in the long term is still being debated. What other structural mechanism would be better suited in improving the long-term effectiveness of the EU ETS? To help in the decision making process, this report presents a multi-criteria analysis. Without prejudging their political support, five policy options have been evaluated that would introduce some flexibility in the EU ETS and potentially ensure its long-term credibility: an auction reserve price, permit supply rules that target a certain corridor of surplus (market stability reserve), permit supply rules that target economic activity, permit supply rules that target overlap with other energy policies and a rolling emissions cap. The assessment of these five policy options was based on a criteria tree and on the EU ETS experts' panel's votes that expressed

  1. Public health economic evaluation of different European Union–level policy options aimed at reducing population dietary trans fat intake12

    Science.gov (United States)

    Mouratidou, Theodora; Livaniou, Anastasia

    2016-01-01

    Background: The adverse relation between dietary trans fatty acid (TFA) intake and coronary artery disease risk is well established. Many countries in the European Union (EU) and worldwide have implemented different policies to reduce the TFA intake of their populations. Objective: The aim of this study was to assess the added value of EU-level action by estimating the cost-effectiveness of 3 possible EU-level policy measures to reduce population dietary TFA intake. This was calculated against a reference situation of not implementing any EU-level policy (i.e., by assuming only national or self-regulatory measures). Design: We developed a mathematical model to compare different policy options at the EU level: 1) to do nothing beyond the current state (reference situation), 2) to impose mandatory TFA labeling of prepackaged foods, 3) to seek voluntary agreements toward further reducing industrially produced TFA (iTFA) content in foods, and 4) to impose a legislative limit for iTFA content in foods. Results: The model indicated that to impose an EU-level legal limit or to make voluntary agreements may, over the course of a lifetime (85 y), avoid the loss of 3.73 and 2.19 million disability-adjusted life-years (DALYs), respectively, and save >51 and 23 billion euros when compared with the reference situation. Implementing mandatory TFA labeling can also avoid the loss of 0.98 million DALYs, but this option incurs more costs than it saves compared with the reference option. Conclusions: The model indicates that there is added value of an EU-level action, either via a legal limit or through voluntary agreements, with the legal limit option producing the highest additional health benefits. Introducing mandatory TFA labeling for the EU common market may provide some additional health benefits; however, this would likely not be a cost-effective strategy. PMID:27680991

    2015-07-30

    Combined Heat and Power (CHP) is an important option for states to consider in developing strategies to meet their emission targets under the US Environmental Protection Agency's Clean Power Plan. This Template is designed to highlight key issues that states should consider when evaluating whether CHP could be a meaningful component of their compliance plans. It demonstrates that CHP can be a valuable approach for reducing emissions and helping states achieve their targets. While the report does not endorse any particular approach for any state, and actual plans will vary dependent upon state-specific factors and determinations, it provides tools and resources that states can use to begin the process, and underscores the opportunity CHP represents for many states. . By producing both heat and electricity from a single fuel source, CHP offers significant energy savings and carbon emissions benefits over the separate generation of heat and power, with a typical unit producing electricity with half the emissions of conventional generation. These efficiency gains translate to economic savings and enhanced competitiveness for CHP hosts, and emissions reductions for the state, along with helping to lower electric bills; and creating jobs in the design, construction, installation and maintenance of equipment. In 2015, CHP represents 8 percent of electric capacity in the United States and provides 12 percent of total power generation. Projects already exist in all 50 states, but significant technical and economic potential remains. CHP offers a tested way for states to achieve their emission limits while advancing a host of ancillary benefits.

    High-priced medications with curative potential, such as the newer hepatitis C therapies, have contributed to the recent growth in pharmaceutical expenditure. Despite the obvious benefits, health care decision makers are just beginning to grapple with questions of how to value and pay for curative therapies that may feature large upfront cost, followed by health benefits that are reaped over a patient's lifespan. Alternative policy options have been proposed to promote high value and financially sustainable use of these therapies. It is unclear which policy options would be most acceptable to health care payer and biomedical manufacturer stakeholders. To (a) briefly review pharmaceutical policy options to address health system affordability and (b) assess the acceptability of alternative policy options to health care payers and biomedical manufacturers before and after an Academy of Managed Care Pharmacy (AMCP) continuing pharmacy education (CPE) session. We searched MEDLINE and Cochran databases for pharmaceutical policy options addressing affordability. With input from a focus group of managed care professionals, we developed CPE session content and an 8-question survey focusing on the most promising policy options. We fielded the survey before and after the CPE session, which occurred as part of the 2016 AMCP Annual Meeting. We first conducted a chi-squared goodness-of-fit test to assess response distributions. Next, we tested how responses differed before and after by using an ordered logit and a multinomial logit to model Likert scale and unordered responses, respectively. Although risk-sharing payments over time remained the most favorable choice before (37%) and after (35%) the CPE session, this choice was closely followed by HealthCoin after the session, which increased in favorability from 4% to 33% of responses (P = 0.001). About half of the respondents (54%) indicated that legislative change is the most significant barrier to the implementation of any

  5. System-wide and Superemitter Policy Options for the Abatement of Methane Emissions from the U.S. Natural Gas System

    2017-12-01

    This work assesses trade-offs between system-wide and superemitter policy options for reducing methane emissions from compressor stations in the U.S. transmission and storage system. Leveraging recently collected national emissions and activity data sets, we developed a new process-based emissions model implemented in a Monte Carlo simulation framework to estimate emissions for each component and facility in the system. We find that approximately 83% of emissions, given the existing suite of technologies, have the potential to be abated, with only a few emission categories comprising a majority of emissions. We then formulate optimization models to determine optimal abatement strategies. Most emissions across the system (approximately 80%) are efficient to abate, resulting in net benefits ranging from 160M to 1.2B annually across the system. The private cost burden is minimal under standard and tax instruments, and if firms market the abated natural gas, private net benefits may be generated. Superemitter policies, namely, those that target the highest emitting facilities, may reduce the private cost burden and achieve high emission reductions, especially if emissions across facilities are highly skewed. However, detection across all facilities is necessary regardless of the policy option and there are nontrivial net benefits resulting from abatement of relatively low-emitting sources.

    Canada is committed under the Kyoto Protocol to reduce greenhouse gas emissions between 2008 and 2012 to a level six percent below the 1990 reference value. To date, however, Canada's greenhouse gas emissions remain far above 1990 levels. Stringent short-term policy measures are needed if Canada is to meet this legally binding commitment. This paper uses a multi-region, multi-commodity static general equilibrium model to quantify the economic impacts of alternative compliance strategies for Canada in the context of climate policies undertaken by other Kyoto Parties. The numerical results confirm fears among Canadian policy makers of larger economic adjustment cost should Canada fulfill its Kyoto commitment solely through domestic action. Comprehensive use of flexible mechanisms - in particular the Clean Development Mechanism - could allow Canada to live up with its international climate policy commitment at a substantially lower economic cost

    Stroetmann, Karl A; Middleton, Blackford

    2011-01-01

    The European Union (EU) sponsored ARGOS project analysed current eHealth policy thinking in both the EU and the USA, compared strategic challenges and outcomes in selected fields, and drafted roadmaps towards developing advanced global approaches for these issues. This policy brief focuses on better understanding the benefits and costs of eHealth investments, assessing their overall socio-economic impact, identifying challenges and success factors, as well as measuring and globally benchmarking the concrete usage of eHealth solutions. These are by now key policy priorities not only of national governments and the European Commission, but also of international institutions like WHO or OECD. There is a strong felt transatlantic need for stocktaking, identifying lessons learned, sharing of experience, and working together to advance these issues for the benefit of health systems. A growing number of national and international activities can be taken advantage of. Recommendations on how to proceed with such transatlantic activities are proposed.

    The present Paper addresses the policy implications of Joint Comprehensive Plan of Action (JCPOA) known as 'Ian Nuclear Deal', implemented on 16{sup th} January of 2016 between the Iran and the P5+1 countries (the U.S., U.K. France, Germany, Russia, and China), along with the EU in technical terms to analyze the Plutonium Route, Uranium Route and the Covert options and Inspections, Monitoring and Verifications. A historical review is presented to understand how the Iranian Nuclear Program is formed. Following is shown the current nuclear facilities in Iran and its capacity to process nuclear materials. It is analyzed the impact of JCPOA in Uranium and Plutonium routes. Covert Options always will be an option, so the most sensitive impact is related to the new monitoring and verification policies that must ensure real control of illegal procedures. The main conclusion is that the deal postpones the Iran's nuclear program for more than a decade (15 years), delaying Iran's nuclear bomb time from a few months to at least one year, although there is a current latent capacity to develop a nuclear bomb in Uranium route. It also gives IAEA inspectors capability to monitor nuclear activities and prevent to possible development to a nuclear bomb. To arrive in this conclusion an extensive technical analyze of impact of JCPOA in Iran's nuclear capabilities was made to discover how effective is the deal to prevent Iran to build, or acquire a nuclear weapon.

  14. Policy options to reduce consumer waste to zero: comparing product stewardship and extended producer responsibility for refrigerator waste.

    Science.gov (United States)

    Nicol, Scott; Thompson, Shirley

    2007-06-01

    Today, over-consumption, pollution and resource depletion threaten sustainability. Waste management policies frequently fail to reduce consumption, prevent pollution, conserve resources and foster sustainable products. However, waste policies are changing to focus on lifecycle impacts of products from the cradle to the grave by extending the responsibilities of stakeholders to post-consumer management. Product stewardship and extended producer responsibility are two policies in use, with radically different results when compared for one consumer product, refrigerators. North America has enacted product stewardship policies that fail to require producers to take physical or financial responsibility for recycling or for environmentally sound disposal, so that releases of ozone depleting substances routinely occur, which contribute to the expanding the ozone hole. Conversely, Europe's Waste Electrical and Electronic Equipment (WEEE) Directive requires extended producer responsibility, whereby producers collect and manage their own post-consumer waste products. WEEE has resulted in high recycling rates of greater than 85%, reduced emissions of ozone-depleting substances and other toxins, greener production methods, such as replacing greenhouse gas refrigerants with environmentally friendly hydrocarbons and more reuse of refrigerators in the EU in comparison with North America.

    This article reviews the state of play of European markets and applications of Radio Frequency Identification (RFID) technology in healthcare in Europe. Based on the current situation the study presents three scenarios for 2020, to describe futures in which the technology and health care sectors develop in different ways. The scenarios were discussed in expert workshops to derive issues that need to be addressed by future policies of the European Union and other stakeholders. The market assessment is based on a review of literature and an analysis of proprietary market data. The information on the state of RFID applications in Health in Europe summarises the results of a literature review, an online Delphi survey, expert interviews and seven cases studies in Europe and the US. The policy analysis is based on the outcomes of a scenario gaming workshop with experts from academia, industry, healthcare providers, policymakers and representatives of patient organisations.

    2016-12-01

    Peer education has long been seen as a key health promotion strategy and an important tool in preventing HIV infection. In South African schools, it is currently one of the strategies employed to do so. Based on both a recent research study of peer education across 35 schools and drawing on multiple previous studies in South Africa, this paper examines the key elements of peer education that contribute to its effectiveness and asks how this aligns with current educational and health policies. From this research, it summarises and proposes shared goals and aims, minimum standards of implementation and reflects on the necessary infrastructure required for peer education to be effective. In light of these findings, it offers policy recommendations regarding who should be doing peer education and the status peer education should have in a school's formal programme.

    Universal access to health care in most western European countries has been a given for many decades; however, macroeconomic developments and increased pressure on health care budgets could mean the status quo cannot be maintained. As populations age, a declining proportion of economically active citizens are being required to support a larger burden of health and social care, while increasing availability of novel technologies for extending and improving life continues to push health care costs upwards. With health expenditure continuing to rise as a proportion of national income, concerns are raised about the current and future financial sustainability of Organisation for Economic Co-Operation and Development (OECD) health care systems. Against this backdrop, a discussion about options to fund health care in the future, including whether to raise additional health care finance (and the ways to do so), reallocate resources and/or ration services becomes very pertinent. This study elicits preferences among a group of key stakeholders (payers, providers, government, academia and health-related industry) on the issue of health care financial sustainability and the future funding of health care services, with a view to understanding the different degrees of acceptability between policy interventions and future funding options as well as their feasibility. We invited 842 individuals from academia, other research organisations (eg. think tanks), national health services, providers, health insurance organisations, government representatives and health-related industry and related advisory stakeholders to participate in an online survey collecting preferences on a variety of revenue-generating mechanisms and cost/demand reducing policies. Respondents represented the 28 EU member states as well as Norway, Iceland, Switzerland, Australia, Russian Federation, Canada and New Zealand. We received 494 responses to our survey from all stakeholder groups. Across all groups, the

    UN-Energy was created in 2004 as the United Nations' principal interagency mechanism in the field of energy. Its creation responds to a request in the Johannesburg Plan of Implementation, adopted by the 2002 World Summit on Sustainable Development, for a new collaborative mechanism between UN agencies, programmes and institutions. UN-Energy has published several reports. The first was prepared for the September 2005 World Summit, 'The Energy Challenge for Achieving the Millennium Development Goals', showing the key role energy access plays for countries to achieve the MDGs. A second report was presented at the May 2006 session of the UN Commission on Sustainable Development (CSD-14), 'Energy in the United Nations: An Overview of UN-Energy Activities'. For the May 2007 CSD-15 UN-Energy brought forward 'Sustainable Bio-Energy: A Framework for Decision-Makers' to help inform dialogue in one critical area of future energy policy choice. Another critical energy policy issue is how renewable energy can be promoted as countries plan for sustainable development. UN-Energy therefore decided to look at how the tools for energy modelling could be evolved. In May 2006, for CSD-14, UN-Energy presented 'Assessing Policy Options for Increasing the Use of Renewable Energy for Sustainable Development: Modelling Energy Scenarios for Ghana'. The Ghana study was carried out by five UN organizations and the Energy Commission of Ghana. It was led by the International Atomic Energy Agency (IAEA) and included the Department of Economic and Social Affairs (DESA) in the UN Secretariat, the Food and Agriculture Organization (FAO), the UN Environment Programme (UNEP) and the UN Industrial Development Organization (UNIDO). UN-Energy now presents a similar study for Sichuan, China. Together these two reports are the first UN-Energy reports to present analytic results from interagency cooperation that, without UN-Energy, would not have happened. This report analyzes alternative provincial

  20. From Market Uncertainty to Policy Uncertainty for Investment in Power Generation: Real Options for NPP on Electricity Market

    In the electricity sector, market participants must make decisions about capacity choice in a situation of radical uncertainty about future market conditions. Sector is normally characterised by non-storability and periodic and stochastic demand fluctuations. In these cases capacity determination is a decision for the long term, whereas production is adjusted in the short run. Capacities need to be installed well in advance (decision for investment even earlier because of long construction time and even longer in case of NPP to prepare all needed legal, financial and physical infrastructure), at times when firms face considerable demand and cost uncertainty when choosing their capacity. Paper looks on the main contributions in investment planning under uncertainty, in particular in the electricity market for capital intensive investments like NPP. The relationship between market and non-market factors (recent UK policy example) in determining investment signals in competitive electricity markets was analysed. Paper analyse the ability of competitive electricity markets to deliver the desired quantity and type of generation capacity and also investigates the variety of market imperfections operating in electricity generation and their impact on long-term dynamics for generation capacity, the most capital-intensive of the liberalised functions in the electricity supply industry. Paper analyses how price formation influences investment signals. Today, investment decisions are made by several operators that act independently. Number of factors (including market power, wholesale price volatility, lack of liquidity in the wholesale and financial market, policy and regulatory risks etc.) contribute to polluting the price signal and generating sub-optimal behaviour. Climate change policies can easily distort market signals, insulating renewables generation from market dynamics. This in turn reduces the proportion of the market that is effectively opened to competitive

    This study aims to explore new or reformed policies to be adopted by the Dutch government to encourage private sector investments in climate-friendly technologies in developing countries. A literature review of barriers to climate-friendly investments and of directions for solutions has been complemented with a number of in-depth interviews with stakeholders representing the major actors involved in investment projects (project sponsors, financing institutions, institutional investors and government). The barrier analysis has resulted in the following list of key obstacles to climate-friendly investments: (1) Lack of a sound, transparent and stable enabling environment for investing in developing countries; (2) Shortage of experienced and creditworthy sponsors; (3) High specific project risks; (4) Overestimation investment risks related to (sustainable) investments in developing countries in general (risk perspective); (5) Additional costs of climate-friendly technologies; (6) Shortage of risk capital; (7) Insufficient guarantee mechanisms; (8) Lack of know-how on public-private partnership structures and on financial design; and (9) Lack of insight how corporate social responsibility can be operationalised. Four main gaps have been identified on the basis of an assessment of current Dutch policies and instruments: (1) Shortage of instruments to directly promote investments; (2) Underdeveloped guarantee instruments; (3) Too restrictive cap on project size in financial schemes; (4) Lack of support in operationalising the concept of corporate social responsibility. Four areas for new or intensified policies have been identified based on the barrier and gap analysis: (1) Direct promotion of (potentially large scale) investments, including: (a) Supporting (the establishment of) sponsor companies developing sustainable energy projects in developing countries; (b) Making risk capital available; (c) Creating investment credit facilities; (d) Making development capital in

    This chapter focuses on energy options as a means of managing exposure to energy prices. An intuitive approach to energy options is presented, and traditional definitions of call and put options are given. The relationship between options and swaps, option value and option exercises, commodity options, and option pricing are described. An end-user's guide to energy option strategy is outlined, and straight options, collars, participating swaps and collars, bull and bear spreads, and swaption are examined. Panels explaining the defining of basis risk, and discussing option pricing and the Greeks, delta hedging, managing oil options using the Black-Scholes model, caps, floors and collars, and guidelines on hedging versus speculation with options are included in the paper

    Abatement cost is the main concern for climate change mitigation and the key factor for mitigation cost is technological change. This study established an integrated economic, energy, environmental, dynamic, computable general equilibrium (CGE) model representing endogenous technological change for China's climate change policy analysis. This study analyzed and compared the economic impact of different approaches to mitigation commitments as well as the potential role of technological change in the formulation of mitigation targets and commitments, taking into account China's climate policy-making needs based on the current international climate negotiation process. The results show that, absolute emission limits similar to the Kyoto Protocol will seriously impede the future economic development of China, while the impact of an 80% reduction in carbon intensity, forecast for 2050 based on the 2005 level, is relatively small. Technological change can promote economic growth, improve energy efficiency and reduce carbon intensity per unit of output through the substitution of production factors. Consequently it can reduce marginal abatement cost and related GDP loss by mitigation. At the same time it can increase mitigation potentials and extend the emission reduction amount, showing that consideration of the impact of technological change when deciding the emission reduction targets is necessary.

    In 2002 the German Parliament decided to exempt biofuels from the gasoline tax to increase their competitiveness compared to conventional gasoline. The policy to promote biofuels is being justified by their allegedly positive effects on climate, energy, and agricultural policy goals. An increased use of biofuels would contribute to sustainable development by reducing greenhouse-gas emissions and the use of non-renewable resources. The paper takes a closer look at bio-ethanol as a substitute for gasoline. It analyzes the underlying basic German, European, and worldwide conditions that provide the setting for the production and promotion of biofuels. It is shown that the production of bio-ethanol in Germany is not competitive and that imports are likely to increase. Using energy and greenhouse-gas balances we then demonstrate that the promotion and a possible increased use of bio-ethanol to reduce greenhouse-gas emissions are economically inefficient and that there are preferred alternative strategies. In addition, scenarios of the future development of the bio-ethanol market are derived from a model that allows for variations in all decisive variables and reflects the entire production and trade chain of bio-ethanol, from the agricultural production of wheat and sugar beet to the consumption of bio-ethanol in the fuel sector.

    Full Text Available This paper deals with the steady state analysis of batch arrival retrial queueing system with two types of service under modified vacation policy, where each type consists of an optional re-service. An arriving batch may balk the system at some particular times. After the completion of each types of service the customers may re-service of the same type without joining the orbit or may leave the system. If the orbit is empty at the service completion of each types of service, the server takes at most J vacations until at least one customer is received in the orbit when the server returns from a vacation. Busy server may breakdown at any instance and the service channel will fail for a short interval of time. The steady state probability generating function for system/orbit size is obtained by using the supplementary variable method. Some system performance measures and numerical illustrations are discussed.

    The growing economies of China and India have increased global anxieties over dwindling fossil fuel resources. Regional countries in central Asia have advocated for more extensive strategic partnerships within the oil and gas industry as insurance against the pressures of more powerful nations. However, non-traditional threats such as terrorism raise serious questions about critical oil and gas infrastructure protection in central Asia. This paper assessed the vulnerability and threats inherent in protecting the critical oil and gas infrastructure of Central Asia, with a specific focus on Kazakhstan, Turkmenistan, Uzbekistan, and the region of Xinjiang in China. An-depth analysis of the development strategies, terrorist threats, and water issues confronted by Central Asian powers was conducted to demonstrate their vulnerability. The analysis was then used to consider options available for managing oil and gas infrastructure in the regions. It was observed that different perceptions and technological difficulties have made cooperation on critical oil and gas infrastructure protection less important than national sovereignty and domestic stability. It was concluded that a low-key approach to homeland security and oil and gas infrastructure may be the best strategy for Central Asia and China. 44 refs.

    Full Text Available This study estimates the fiscal, energy, and environmental tradeoffs involved in supplying California’s future energy needs. An integrated framework is developed whereby an econometric forecasting system of California energy demand is coupled with engineering-economic models of energy supply, and economic impacts are estimated using input-output models of the California economy. A baseline scenario in which California relies on imported electricity to meet future demand is then compared against various energy supply development scenarios over the forecast horizon (2012–2035. The results indicate that if California implements its renewable portfolio standard (RPS, there will be a substantial net cost in terms of value added, employment, and state tax revenues because the economic benefits of building capacity are outweighed by higher energy prices. Although carbon emissions fall, the cost per ton of avoided emissions is well above market prices. Building out natural gas fired generation capacity also leads to losses compared to the baseline, although the impacts are relatively minor. Meanwhile, a strategy of replacing imported crude oil and natural gas with domestic production using indigenous resources increases gross state product, employment, and tax revenues, with minimal impact on carbon emissions. This option could, therefore, help mitigate the costs of California meeting its RPS commitment.

    It is feasible for EU member states to meet their commitments regarding transport fuels under the Renewable Energy Directive (RED) and the Fuel Quality Directive (FQD) without resorting to biofuels from food crops. The RED target (10% renewable transport energy in 2020) can be met by a mix of measures aimed at improving energy efficiency, combined with a strong focus on growth of renewable electricity use and biofuels and biomethane from waste and residues. These measures also contribute to the FQD target (6% reduction in carbon intensity of fuels by 2020), but will need to be complemented by other measures such as reduced flaring and venting during oil production. The report shows how EU transport energy policy could reduce its reliance on biofuels from food crops that are likely to cause land use change. This alternative vision for the transport sector in 2020 would cut CO2 emissions by 205 million tonnes.

  10. How do international trade obligations affect policy options for obesity prevention? Lessons from recent developments in trade and tobacco control.

    Regulatory measures, including taxes and subsidies on food and beverage products, food labelling requirements, regulation of food content and regulation of food marketing, have been proposed to encourage healthier eating and prevent obesity. The objective of this article is to explore the extent to which international trade agreements affect governments' choices to use such regulatory measures. It reviews key provisions of relevant World Trade Organization (WTO) agreements and their implications. Some insights can be gained by examining 2 recent developments in the WTO regarding tobacco control: a current dispute involving Australia's plain packaging law and its effect on trademarks, and a recent decision involving the United States law banning flavoured cigarettes. This decision said that the ban did not restrict trade more than necessary to fulfil its legitimate health objective, but it was discriminatory because it banned imported products (clove cigarettes) while exempting domestic products (menthol cigarettes) with similar characteristics. The conclusion we can draw from this decision is that WTO member states probably enjoy a significant degree of latitude in developing food regulations as part of an obesity prevention strategy, so long as those do not disproportionately affect imported products and therefore raise questions of discrimination. The approach taken in this case encourages the adoption of public health policies that are consistent with strong scientific evidence, but may restrict governments' ability to make political compromises, which could frustrate some proposals. The ongoing development of WTO law will continue to affect policy choices in public health. Copyright © 2013 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

    Full Text Available Hauser et al. (2002 suggest that the human language faculty emerged as a genetic innovation in the form of what is called here a ‘keystone factor’—a single, simple, formal mental capability that, interacting with the pre-existing faculties of hominid ancestors, caused a cascade of effects resulting in the language faculty in modern humans. They take Merge to be the keystone factor, but instead it is posited here that Merge is the pre-existing mechanism of thought made viable by a principle that permits relations interpretable at the interfaces to be mapped onto c-command. The simplified minimalist architecture proposed here respects the keystone factor as closely as possible, but is justified on the basis of linguistic analyses it makes available, including a relativized intervention theory applicable across Case, scope, agreement, selection and linearization, a derivation of the A/A’-distinction from Case theory, and predictions such as why in situ wh-interpretation is island-insensitive, but susceptible to intervention effects.

    There is concern over increasing prevalence of non-nucleoside reverse-transcriptase inhibitor (NNRTI) resistance in people initiating antiretroviral therapy (ART) in low-income and middle-income countries. We assessed the effectiveness and cost-effectiveness of alternative public health responses in countries in sub-Saharan Africa where the prevalence of pretreatment drug resistance to NNRTIs is high. The HIV Synthesis Model is an individual-based simulation model of sexual HIV transmission, progression, and the effect of ART in adults, which is based on extensive published data sources and considers specific drugs and resistance mutations. We used this model to generate multiple setting scenarios mimicking those in sub-Saharan Africa and considered the prevalence of pretreatment NNRTI drug resistance in 2017. We then compared effectiveness and cost-effectiveness of alternative policy options. We took a 20 year time horizon, used a cost effectiveness threshold of US$500 per DALY averted, and discounted DALYs and costs at 3% per year. A transition to use of a dolutegravir as a first-line regimen in all new ART initiators is the option predicted to produce the most health benefits, resulting in a reduction of about 1 death per year per 100 people on ART over the next 20 years in a situation in which more than 10% of ART initiators have NNRTI resistance. The negative effect on population health of postponing the transition to dolutegravir increases substantially with higher prevalence of HIV drug resistance to NNRTI in ART initiators. Because of the reduced risk of resistance acquisition with dolutegravir-based regimens and reduced use of expensive second-line boosted protease inhibitor regimens, this policy option is also predicted to lead to a reduction of overall programme cost. A future transition from first-line regimens containing efavirenz to regimens containing dolutegravir formulations in adult ART initiators is predicted to be effective and cost-effective in

    2013-01-01

    Full Text Available This paper investigates the causal relationship among electricity supply, fossil fuel consumption, CO2 emissions and economic growth in Nigeria for the period 1971-2009, in a multivariate framework.Using the bound test approach to cointegration, we found a short-run as well as a long-run relationship among the variables with a positive and statistically significant relationship between CO2 emissions and fossil fuel consumption. The findings also indicate that economic growth is associated with increased CO2 emissions while a positive relationship exists between electricity supply and CO2 emissions revealing the poor nature of electricity supply in Nigeria. Further, the Granger causality test results indicate that electricity supply has not impacted significantly on economic growth in Nigeria. The results also strongly imply that policies aimed at reducing carbon emissions in Nigeria will not impede economic growth. The paper therefore concludes that a holistic energy planning and investment in energy infrastructure is needed to drive economic growth. In the long-run however, it is possible to meet the energy needs of the country, ensure sustainable development and at the same time reduce CO2 emissions by developing alternatives to fossil fuel consumption, the main source of CO2 emissions.

    The US Graduate Medical Education (GME) system is failing to produce primary care physicians in sufficient quantity or in locations where they are most needed. Decentralization of GME training has been suggested by several federal advisory boards as a means of reversing primary care maldistribution, but supporting evidence is in need of updating. We assessed the geographic relationship between family medicine GME training sites and graduate practice location. Using the 2012 American Medical Association Masterfile and American Academy of Family Physicians membership file, we obtained the percentage of family physicians in direct patient care located within 5, 25, 75, and 100 miles and within the state of their family medicine residency program (FMRP). We also analyzed the effect of time on family physician distance from training site. More than half of family physicians practice within 100 miles of their FMRP (55%) and within the same state (57%). State retention varies from 15% to 75%; the District of Columbia only retains 15% of family physician graduates, while Texas and California retain 75%. A higher percentage of recent graduates stay within 100 miles of their FMRP (63%), but this relationship degrades over time to about 51%. The majority of practicing family physicians remained proximal to their GME training site and within state. This suggests that decentralized training may be a part of the solution to uneven distribution among primary care physicians. State and federal policy-makers should prioritize funding training in or near areas with poor access to primary care services.

    2010-01-01

    Background The prevalence of both chronic diseases and multi-morbidity increases with longer life spans. As Australia's population ages, the aged care sector is under increasing pressure to ensure that quality aged care is available. Key to responding to this pressure is leadership and management capability within the aged care workforce. A systematic literature review was conducted to inform the policy development necessary for the enhancement of clinical and managerial leadership skills of middle managers within residential aged care. Methods Using scientific journal databases, hand searching of specialist journals, Google, snowballing and suggestions from experts, 4,484 papers were found. After a seven-tiered culling process, we conducted a detailed review (narrative synthesis) of 153 papers relevant to leadership and management development in aged care, incorporating expert and key stakeholder consultations. Results • Positive staff experiences of a manager's leadership are critical to ensure job satisfaction and workforce retention, the provision of quality care and the well-being of care recipients, and potentially a reduction of associated costs. • The essential attributes of good leadership for aged care middle management are a hands-on accessibility and professional expertise in nurturing respect, recognition and team building, along with effective communication and flexibility. However, successful leadership and management outcomes depend on coherent and good organisational leadership (structural and psychological empowerment). • There is inadequate preparation for middle management leadership roles in the aged care sector and a lack of clear guidelines and key performance indicators to assess leadership and management skills. • Theory development in aged care leadership and management research is limited. A few effective generic clinical leadership programs targeting both clinical and managerial leaders exist. However, little is known regarding

To achieve no CO2 and GHG emissions in the energy sector, to have it be completely market based, energy efficient and technologically approved, a unique climate and energy policy is a necessary option and the only viable option to accomplish previously agreed climate goals.(author).

  1. The Supply of Medical Radioisotopes. Policy Options for Ensuring Long-term Supply Security of Molybdenum-99 and/or Technetium-99m Produced Without Highly Enriched Uranium Targets

    2012-01-01

    Following the shortages of the key medical radioisotopes, molybdenum-99 ( 99 Mo) and its daughter technetium-99m (' 99m Tc), the OECD-Nuclear Energy Agency (NEA) created the High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR). Since 2009, this group has identified the reasons for the isotope shortages and developed a policy approach to address the challenges to a long-term secure supply of these important medical isotopes. On top of the ongoing concerns related to long-term reliability, all current long-term major 99 Mo-producing nations have agreed to convert to using low-enriched uranium (LEU) targets for the production of 99 Mo. This decision was made based on important nonproliferation reasons; however, the conversion will have potential impacts on the global supply chain - both in terms of costs and available capacity. Recognising that conversion is important and will occur, and also recognising the need to ensure a long-term secure supply of 99 Mo/' 99m Tc, the NEA, along with stakeholders, examined potential policy options that could be used by to ensure a reliable supply of 99 Mo and/or ' 99m Tc produced without highly enriched uranium (HEU), consistent with the time frames and policies of the HLG-MR. This discussion paper provides the various policy options available to governments to encourage a reliable supply of 99 Mo and/or ' 99m Tc produced without HEU. The examination of these options was done through the lens of ensuring a reliable supply, consistent with the time frames and policies of the HLG-MR. The options described in this document are meant to meet this objective by taking one of three general actions: - Making the option of purchasing or producing non-HEU-based 99 Mo and/or ' 99m Tc more attractive. - Making the option of purchasing or producing HEU-based 99 Mo and/or ' 99m Tc less attractive. - Limiting access to HEU-based 99 Mo and/or ' 99m Tc. This paper presents the options in each category and provides some views

  2. Climate targets for all countries: the options

    2001-01-01

    This paper assesses five options for targets that could be taken by all countries to meet the ultimate objective of the Climate Change Convention: fixed, binding targets, dynamic targets; non-binding targets; sectoral targets, policies and measures. Each is evaluated according to criteria of environmental effectiveness, cost-effectiveness, contribution to economic growth and sustainable development, and equity. While fixed, binding targets continue to be viable for industrialized countries, they do not seem suitable for many developing countries in the near future. Dynamic targets could alleviate developing countries' concerns about constraining their development as well as broader concerns about possible introduction of 'hot air' in a world trading regime; they could also be considered for some or all industrialized countries. Non-binding targets could be politically appealing to developing counties, alleviate fears about development and/or hot air, but might only allow conditional participation in emissions trading by developing countries. Sectoral targets could offer a pragmatic first step - although their cost-effectiveness might be questioned. Finally, targets based on commitments to implement specific policies and measures might drive mitigation action and be part of negotiated packages including financial and technological cooperation. All these options may coexist in the future. (authors)

    Full Text Available Abstract Background The Healthy Options for Nutrition Environments in Schools (Healthy ONES study was an evidence-based public health (EBPH randomized group trial that adapted the Institute for Healthcare Improvement’s (IHI rapid improvement process model to implement school nutrition policy and environmental change. Methods A low-income school district volunteered for participation in the study. All schools in the district agreed to participate (elementary = 6, middle school = 2 and were randomly assigned within school type to intervention (n = 4 and control (n =4 conditions following a baseline environmental audit year. Intervention goals were to 1 eliminate unhealthy foods and beverages on campus, 2 develop nutrition services as the main source on campus for healthful eating (HE, and 3 promote school staff modeling of HE. Schools were followed across a baseline year and two intervention years. Longitudinal assessment of height and weight was conducted with second, third, and sixth grade children. Behavioral observation of the nutrition environment was used to index the amount of outside foods and beverages on campuses. Observations were made monthly in each targeted school environment and findings were presented as items per child per week. Results From an eligible 827 second, third, and sixth grade students, baseline height and weight were collected for 444 second and third grade and 135 sixth grade students (51% reach. Data were available for 73% of these enrolled students at the end of three years. Intervention school outside food and beverage items per child per week decreased over time and control school outside food and beverage items increased over time. The effects were especially pronounced for unhealthy foods and beverage items. Changes in rates of obesity for intervention school (28% baseline, 27% year 1, 30% year 2 were similar to those seen for control school (22% baseline, 22% year 1, 25% year 2 children

  5. On-Chip Dielectrophoretic Separation and Concentration of Viable, Non-Viable and Viable but Not Culturable (VBNC) Escherichia coli

    2012-04-12

    Although bacterial culture remains the gold standard for detection of viable bacteria in environmental specimens, the typical time requirement of twenty-four hours can delay and even jeopardize appropriate public health intervention. In addition, culture is incapable of detecting viable but not culturable (VBNC) species. Conversely, nucleic acid and antibody-based methods greatly decrease time to detection but rarely characterize viability of the bacteria detected. Through selection by membrane permeability, the method described in this work employs positive dielectrophoresis (pDEP) for separation and purification of viable and VBNC species from water and allows concentration of bacteria for downstream applications.

  8. The future of the nuclear option

    Frost, B.R.T.

    1992-01-01

    This paper reports on the future of the nuclear option. No nuclear power reactors have been ordered in the U.S.A. since 1975, but the number of operating reactors has increased to the 115 operating today. The demand for electric power continues to grow. At this time, concern over the environmental effects of fossil fuels has grown; global warming and acid rain effects are major determinants of energy policy. In these circumstances nuclear power may be the only viable option to meet the growing demand for electricity. In the past decade the nuclear power industry has addressed its major critics by standardizing designs, improving operator training, and developing safe methods of disposing of waste products. Fast breeder reactors have taken a new lease on life through the American Integral Fast Reactor (IFR) design which is inherently safe, proliferation resistant, and helps the waste-disposal problem. It will probably not be commercially available until well into the next century. The extension of reactor life raises questions of long-term thermal and radiation effects

    Haddad, Georges

    This paper is a study on functional differential inclusions with memory which represent the multivalued version of retarded functional differential equations. The main result gives a necessary and sufficient equations. The main result gives a necessary and sufficient condition ensuring the existence of viable trajectories; that means trajectories remaining in a given nonempty closed convex set defined by given constraints the system must satisfy to be viable. Some motivations for this paper can be found in control theory where F( t, φ) = { f( t, φ, u)} uɛU is the set of possible velocities of the system at time t, depending on the past history represented by the function φ and on a control u ranging over a set U of controls. Other motivations can be found in planning procedures in microeconomics and in biological evolutions where problems with memory do effectively appear in a multivalued version. All these models require viability constraints represented by a closed convex set.

    Ibitoye, F.I.; Akinbami, J.-F.K.

    1999-01-01

    Recent studies indicate that Nigeria's CO 2 budget was about 164 million tonnes (MTons) in 1990, of which the energy sector contributed close to 55%. It is expected that CO 2 emissions emanating from the energy sector will increase from 90 MTons in 1990 to about 3 times this value in another 30 years, assuming a least-cost moderate development scenario. A number of viable CO 2 -mitigation options have already been identified in the energy sector, some of them the so-called 'win-win' options. As attractive as some of these options might appear, their implementation will depend on the removal of certain barriers. These barriers include a lack of legislative framework, a lack of awareness, a lack of access to appropriate technology, as well as inappropriate energy-pricing policies, among others. The paper presents an overview of Nigeria's energy-sector, the CO 2 mitigation-options, the factors militating against implementation of the options, and some policy recommendations for removal of the barriers.

    This study deals with the evolution of (scalar) attributes (resources or income in evolutionary demography or economics, position in traffic management, etc.) of a population of “mobiles” (economic agents, vehicles, etc.). The set of mobiles sharing the same attributes is regarded as an instantaneous cohort described by the number of its elements. The union of instantaneous cohorts during a mobile window between two attributes is a cohort. Given a measure defining the number of instantaneous cohorts, the accumulation of the mobile attributes on a evolving mobile window is the measure of the cohort on this temporal mobile window. Imposing accumulation constraints and departure conditions, this study is devoted to the regulation of the evolutions of the attributes which are1.viable in the sense that the accumulations constraints are satisfied at each instant;2.and, among them, optimal, in the sense that both the duration of the temporal mobile window is maximum and that the accumulation on this temporal mobile window is the largest viable one. This value is the “accumulation valuation” function. Viable and optimal evolutions under accumulation constraints are regulated by an “implicit Volterra integro-differential inclusion” built from the accumulation valuation function, solution to an Hamilton–Jacobi–Bellman partial differential equation under constraints which is constructed for this purpose.

    The Options Study has been conducted for the purpose of evaluating the potential of alternative integrated nuclear fuel cycle options to favorably address the issues associated with a continuing or expanding use of nuclear power in the United States. The study produced information that can be used to inform decisions identifying potential directions for research and development on such fuel cycle options. An integrated nuclear fuel cycle option is defined in this study as including all aspects of the entire nuclear fuel cycle, from obtaining natural resources for fuel to the ultimate disposal of used nuclear fuel (UNF) or radioactive wastes. Issues such as nuclear waste management, especially the increasing inventory of used nuclear fuel, the current uncertainty about used fuel disposal, and the risk of nuclear weapons proliferation have contributed to the reluctance to expand the use of nuclear power, even though it is recognized that nuclear power is a safe and reliable method of producing electricity. In this Options Study, current, evolutionary, and revolutionary nuclear energy options were all considered, including the use of uranium and thorium, and both once-through and recycle approaches. Available information has been collected and reviewed in order to evaluate the ability of an option to clearly address the challenges associated with the current implementation and potential expansion of commercial nuclear power in the United States. This Options Study is a comprehensive consideration and review of fuel cycle and technology options, including those for disposal, and is not constrained by any limitations that may be imposed by economics, technical maturity, past policy, or speculated future conditions. This Phase II report is intended to be used in conjunction with the Phase I report, and much information in that report is not repeated here, although some information has been updated to reflect recent developments. The focus in this Options Study was to

    Large numbers of viable Giardia muris trophozoites were isolated from the duodenum of experimentally infected mice 6 days after inoculation with 1,000 G. muris cysts. A series of shaking, incubation, and washing steps in the presence of the broad-spectrum antibiotic piperacillin readily provided 4.9 +/- 1.5 x 10(5) G. muris trophozoites per mouse, free of detectable contaminant organisms. Anaerobic and microaerophilic culturing and scanning electron microscopy demonstrated axenic status and high purity of the isolates. The viability of trophozoites was 98 +/- 2%. Application of this technique should permit novel immunological and epidemiological analyses of G. muris infection and biochemical investigations of this protozoan parasite.

    2016-01-01

    The growing demand of maize silage for biogas production in Northern Italy has triggered an intense debate concerning land rents, maize prices and their possible negative consequences on important agri-food chains. The aim of this work is to quantify the extent to which the rapid spread of biogas raised the maize price at regional level, increasing the demand of land for energy crops. For this purpose we applied a partial-equilibrium framework simulating the agricultural sector and the biogas industry in Lombardy, under two alternative schemes of subsidization policy. Results show that policy measures implemented in 2013 – reducing the average subsidy per kWh – may contribute to enforce the complementarity of the sector with agri-food chains, decreasing the competition between energy and non-energy uses. Compared to the old scheme, maize demand for biogas would decrease, lessening the market clearing price (as well as feed opportunity cost for livestock sector) and reducing land demand for energy purposes. - Highlights: •We investigate biogas production in Lombardy under two alternative policy scenarios. •We model the biogas sector using a partial equilibrium approach. •Past legislation significantly increases maize demand and its market clearing price. •New incentive system favors manure based plants (130 kWe) decreasing maize demand. •Wider, new policy mitigates past distortions and negative effects on maize price.

    The economic feasibility of on-farm biogas energy production was investigated for swine and dairy operations under Nova Scotia, Canada farming conditions, using net present value (NPV), internal rate of return (IRR), and payback period (PP) economic decision criteria. In addition, the effects of selected environmental and 'green' energy policy schemes on co-generation of on-farm biogas energy production and other co-benefits from anaerobic digestion of livestock manure were investigated. Cost-efficiencies arising from economies of scale for on-farm anaerobic biogas production were found for swine farms, and less so for dairy production systems. Without incentive schemes, on-farm biogas energy production was not economically feasible across the farm size ranges studied, except for 600- and 800-sow operations. Among single policy schemes investigated, green energy credit policy schemes generated the highest financial returns, compared to cost-share and low-interest loan schemes. Combinations of multiple policies that included cost-share and green energy credit incentive schemes generated the most improvement in financial feasibility of on-farm biogas energy production, for both swine and dairy operations

    Techniques used in conventional project appraisal are mathematically very simple in comparison to those used in reservoir modelling, and in the geosciences. Clearly it would be possible to value assets in mathematically more sophisticated ways if it were meaningful and worthwhile so to do. The DCf approach in common use has recognized limitations; the inability to select a meaningful discount rate being particularly significant. Financial Theory has advanced enormously over the last few years, along with computational techniques, and methods are beginning to appear which may change the way we do project evaluations in practice. The starting point for all of this was a paper by Black and Scholes, which asserts that almost all corporate liabilities can be viewed as options of varying degrees of complexity. Although the financial presentation may be unfamiliar to engineers and geoscientists, some of the concepts used will not be. This paper outlines, in plain English, the basis of option pricing theory for assessing the market value of a project. it also attempts to assess the future role of this type of approach in practical Petroleum Exploration and Engineering economics.

    Are hospital-based outpatient interdisciplinary clinics a financially viable alternative for caring for our burgeoning population of older adults in America? Although highly popular, with high patient satisfaction rates among older adults and their families, senior health clinics (SHCs) can be expensive to operate, with limited quantifiable health outcomes. This study analyzed three geriatric hospital-based interdisciplinary clinics in rural Arkansas by examining their patient profiles, revenues, and expenses. It closely examined the effects of the downstream revenue using the multiplier effect and acknowledged other factors that weigh heavily on the success of SHCs and the care of older adults. The findings highlight the similarities and differences in the three clinics' operating and financial structures in addition to the clinics' and providers' productivity. The analysis presents an evidence-based illustration that SHCs can break even or lose large amounts of money.

    Is community forestry emerging from the shadows? The evidence shows that locally controlled enterprises can be economically viable, and often build on stronger social and environmental foundations than the big private-sector players. Certainly this is an industry in need of a shakeup. Many forests have become flashpoints where agro-industry, large-scale logging concerns and conservation interests clash, while forest-dependent communities are left out in the cold. Meanwhile, governments – driven by concerns over the climate impacts of deforestation – are having to gear up for legal, sustainable forestry production. Community forestry could be crucial to solving many of these challenges. By building on local core capabilities and developing strategic partnerships, they are forging key new business models that could transform the sector.

  10. Introduce of Viable But Nonculturable Bacteria

    Full Text Available Viable-But-Nonculturable-State (VBNC is the condition in which bacteria fail to grow on their routine bacteriological media where they would normally grow and develop into colonies, but are still alive and capable of renewed metabolic activity. VBNC state is useful for evaluating public health and for ascertaining the sterility of drinking water, pharmaceuticals, and foodstuff. A number of bacteria, mostly pathogenic to humans, have been proved to enter into this state in response to natural stresses such as starvation, incubation out of optimum growth temperature, increased osmotic pressure, etc. Once in the VBNC state, they undergo various physiological, structural, and genetic alterations. These alterations result in reduced cell size, conversion from bacilli to coccid, thickened cell walls, and peptidoglycan gaining many cross links. Metabolic changes also occur that include reductions in growth, nutrient transport, and respiratory rate; biosynthesis of new protein, and ATP remaining at a constant level. It has been shown that in the VBNC state, some pathogens conserve their virulence properties. Gene expression continues in the VBNC cell. Nucleic acids remain intact in the early VBNC phase but they gradually undergo degradation with prolonged VBNC. Cytological methods such as direct viable count and reduction of tetrazolium salts, and molecular methods such as reverse transcription polymerase chain reaction and green fluorescent protein have been used for the study of VBNC. Resuscitation from VBNC state starts when the inducing factor(s is/are lifted. Factors that help the resuscitation of VBNC bacteria include addition of certain nutrients and chemicals, introduction of a few culturable cells into the VBNC cell population, and passage through the animal host. As virulence properties are sustained during the VBNC phase, special care must be paid when evaluating sterility of drinking water.

    The study, along with parallel studies for the EU and Japan, was commissioned by WWF to develop policies and measures for emissions reductions that could realistically approach AOSIS's proposed 20% reduction target by 2000. It focuses on carbon dioxide and builds and expands on 'Energy innovations: a prosperous path to a clean environment' (1997). It identified policies and measures in the following sectors: industry, residential and commercial buildings, transport and electric power to reach a climate protection scenario. Amongst many policy routes recommended, key ones are: acceleration of combined heat and power in the industrial sector; more rapid penetration of ethanol in blends with gasoline for transportation fuels; and co-firing of biomass in coal-fired electricity generation. Other actions identified include: increased use of renewables; allowance trading systems to cap emissions of SO{sub 2}, NOx, CO{sub 2} and particulates; investment tax credits, R & D support, and introducing appliance and building standards for energy consumption. 53 refs., 8 figs., 3 tabs.

    2014-09-01

    Full Text Available The present study was based on the reverse transcription polymerase chain reaction (RT-PCR of the 16S ribosomal nucleic acid (rRNA of Mycoplasma for detection of viable Mycoplasma gallisepticum. To determine the stability of M. gallisepticum 16S rRNA in vitro, three inactivation methods were used and the suspensions were stored at different temperatures. The 16S rRNA of M. gallisepticum was detected up to approximately 20–25 h at 37 °C, 22–25 h at 16 °C, and 23–27 h at 4 °C. The test, therefore, could detect viable or recently dead M. gallisepticum (< 20 h. The RT-PCR method was applied during an in vivo study of drug efficacy under experimental conditions, where commercial broiler-breeder eggs were inoculated with M. gallisepticum into the yolk. Hatched chicks that had been inoculated in ovo were treated with Macrolide 1. The method was then applied in a flock of day 0 chicks with naturally acquired vertical transmission of M. gallisepticum, treated with Macrolide 2. Swabs of the respiratory tract were obtained for PCR and RT-PCR evaluations to determine the viability of M. gallisepticum. This study proved that the combination of both PCR and RT-PCR enables detection and differentiation of viable from non-viable M. gallisepticum.

  14. Commercial insurance vs community-based health plans: time for a policy option with clinical emphasis to address the cost spiral.

    Science.gov (United States)

    Amundson, Bruce

    2005-01-01

    The nation continues its ceaseless struggle with the spiraling cost of health care. Previous efforts (regulation, competition, voluntary action) have included almost every strategy except clinical. Insurers have largely failed in their cost-containment efforts. There is a strong emerging body of literature that demonstrates the relationship between various clinical strategies and reductions in utilization and costs. This article describes the organization of health services, including integration of delivery and financing systems, at the community level as a model that effectively addresses the critical structural flaws that have frustrated control of costs. Community-based health plans (CHPs) have been developed and have demonstrated viability. The key elements of CHPs are a legal organizational structure, a full provider network, advanced care-management systems, and the ability to assume financial risk. Common misconceptions regarding obstacles to CHP development are the complexity of the undertaking, difficulty assuming the insurance function, and insured pools that are too small to be viable. The characteristics of successful CHPs and 2 case studies are described, including the types of advanced care-management systems that have resulted in strong financial performance. The demonstrated ability of CHPs to establish financial viability with small numbers of enrollees challenges the common assumption that there is a fixed relationship between health plan enrollment size and financial performance. Organizing the health system at the community/regional level provides an attractive alternative model in the health-reform debate. There is an opportunity for clinical systems and state and federal leaders to support the development of community-based integrated delivery and financing system models that, among other advantages, have significant potential to modulate the pernicious cost spiral.

    Highlights: • Farmers are mainly willing to expand the uptake of mitigation practices they already implement. • Main barriers and enablers to uptake are physical–environmental constraints and personal values. • Farmers consider that agriculture is a “special case” because their function is to produce food. • Lack of incentives is not the main barrier to the uptake of mitigation practices. • Policies should allow differentiation, and mitigation measures should be integrated with other mechanisms. - Abstract: The rural land use sector could potentially mitigate a large amount of GHG emissions. Implementation requires the engagement of farmers and other land managers. Understanding the barriers and enablers for the uptake of these practices is essential both to inform policy-makers and to achieve effective policy outreach. In Scotland, the rural land use sector is subject to a greenhouse gas (GHG) emission reduction target of 21% by 2020 relative to 1990 levels. This study contributes to the body of research on stakeholders’ perspectives about suitability of climate change mitigation practices at the regional level. Mixed-methods were used to collect the data, namely participatory workshops with scientists and relevant stakeholders, a farmer questionnaire, and focus groups with farmers. Findings show that farmers were mainly willing to expand the uptake of mitigation practices they were already implementing because they consider these are the most cost-effective. Barriers to the implementation of mitigation practices are mainly related to physical–environmental constraints, lack of information and education and personal interests and values. Similarly, enablers are also related to physical–environmental factors and personal interests and values. Economic incentives, voluntary approaches and provision of information have been identified by workshop participants as the most favourable approaches needed to promote the uptake of technically feasible

    The discharge of produced waters to coastal estuaries has been common practice on the Texas coast for many years as these discharges are currently exempt from NPDES permitting. A study of the active produced water discharges in Nueces Bay, Texas revealed that all eight effluents were highly toxic as determined by the sea urchin (Arbacia punctulata) fertilization and embryological development assays. An alternative to discharging produced water into coastal estuaries is the use of disposal wells. Inactive wells can be converted to produced water disposal wells. Production records for the Nueces Bay, Texas area reveal that 52% of the gas wells produce less than 100 mcf/d and 50% of the oil wells produce less than 10 b/d. Using conservative estimates, the cost of converting an inactive well to a disposal well was calculated to be $31,500 which could be paid out by a gas well producing as little as 100 mcf/d in 26 months using only 50% of the well's profit. Combining multiple leases to a single disposal well would reduce proportionately the cost to each operation. This study has demonstrated that economically viable disposal options could be achieved in the Nueces Bay area through the imaginative and cooperative formation of produced water disposal ventures. This same model could be applied to produced water discharges in other coastal areas

    The potential benefits of wood energy (forest biomass) for space heating in Canada`s remote communities was discussed. Diesel fuel and heating oil must be transported into these communities to produce electricity and to heat large public buildings. Below the treeline, roundwood is often used to heat private homes. The move toward environmentally sustainable development has focussed much attention on renewable energy technologies such as biomass energy, (i.e. any form of energy derived from plant or animal materials). Wood is the most readily available biomass fuel in remote communities. Woodchips and sawmill waste can be burned in automated biomass heating systems which provide a convenient way to use low-grade wood to heat large buildings or groups of buildings which would not be feasible to heat with roundwood. It was shown that one cord of spruce can produce 1.5 tonnes of woodchips to ultimately displace 300 litres of heating oil. A description of a small-commercial and small-industrial biomass system was presented. The benefits of biomass were described as: (1) direct savings compared to high-cost oil heat, (2) increased circulation of energy dollars inside the community, and (3) employment opportunities in harvesting, processing and operating biomass systems. A steady supply of good quality woodchips to the heating plant must be ensured. 1 ref., 3 figs.

    Saudi Arabia has about 23 million palm trees and it is the second largest producer of dates. The biomass from the trimmed branches of palm trees amount to more than 200,000 tons/year. This biomass waste can be used to produce many commercial products. There are several relevant technologies for conversion of biomass and solid wastes into higher value products. The starting point of the project is the pretreatment of palm solid wastes. Thermogravimetric analysis has been done to understand the pyrolysis behavior of palm date wastes. A fluidized bed (FB) has been designed and to study hydrodynamics and develop optimum conditions for the pyrolysis of palm wastes. A novel fluidized bed test rig has been designed and fabricated to carry out the pyrolysis of palm wastes. The pyrolysis is used to produce activated carbon and the waste can also be readily converted to liquid phenolic products. Liquid products are particularly interesting because they have a higher energy density and can be used to produce adhesives as well as biofuels for use in power generation and transport sector. Experimental results have indicated potential opportunities of using the date biomass waste as a potential fuel in the Kingdom of Saudi Arabia.

    Colostomy irrigation (CI) is the regular irrigation of the bowel for persons with a permanent colostomy of the descending or sigmoid colon. Although this technique was first described in the 1920s, a recent study of 985 WOC nurses found that almost half (47%) do not routinely teach CI to persons with colostomies. In a systematic review (Evidence-Based Report Card) published in this issue of the Journal, we summarized current best evidence concerning the effect of CI on bowel function and found that irrigation reduces the frequency of bowel elimination episodes and allows some patients to reduce or eliminate ongoing use of a pouching system. This article describes techniques for teaching CI and discussed additional findings associated with CI.

    Full Text Available Background: The management of unsalvageable femoral head conditions in the young patient has remained an unresolved dilemma. Articular surface replacement of the hip has recently made some headway in terms of providing near-normal hip joint mechanics and function. However, this surgery has been limited to early stages of arthritis only with reasonable maintenance of head-neck congruity and morphology. Femoral neck fractures, osteonecrosis with large segment collapse, advanced arthritis with femoral incongruity, etc are traditional contraindications to the resurfacing technique. Methods: We present here a report on our series of 20 cases of unsalvageable femoral heads in young patients (age range, 27 to 52yrs, over a twelve month period (Aug 2004 to Jul 2005, treated with the unipolar ASR prosthesis. Fifteen patients (two had bilateral hip pathology had primary or secondary arthritis (degenerative, post-traumatic, ankylosing spondylitis and post-avascular necrosis while three had old operated femoral neck fractures. All patients underwent hip replacement surgery using the Unipolar ASR prosthesis. Results: Clinical and radiological results at 6-month follow up have been very encouraging and warrant further study. At an average of 4 months post-operatively, patients were able to squat, sit on the ground and perform light sporting activities. Conclusions: The Unipolar ASR prosthesis is an extension of the articular resurfacing technique employing similar principles (large size bearings, metal-on-metal interfaces, and has incorporated the advantages of the uncemented technique. We propose that this technique be more frequently used so as to brighten the prognosis of the young active patient with unsalvageable hip conditions, especially in the Asian scenario.

    Hot mix asphalt production equipment has been successfully utilized in the remediation of soils contaminated with petroleum hydrocarbons. This paper reports that there are two major ways in which this equipment can be used to remediate the petroleum contaminated soils; by incorporating the contaminated soil in the hot mix asphalt product or by using the equipment to clean the soil thermally of the contaminant, leaving a clean soil material. Both of these processes have limitations encompassing technical, political, and certainly liability problems. The remediation of contaminated soil in hot mix asphalt facilities is primarily a physical phenomenon relying on laws of heat and mass transfer. Although chemical changes do occur, the primary function of the process is to cause a physical separation of the contaminant from the soils

    Despite the growing pains of the US nuclear power industry, our dependence on nuclear energy for the production of electricity and possibly process heat is likely to increase dramatically over the next few deacades. This statement dismisses fusion as being entirely too speculative to be practical within that time frame. Sometime, between the years 2000 and 2050, fissile material will be in short supply whether it is to fuel existing LWR's or to provide initial fuel inventory for FBR's. The accelerator breeder could produce the fuel shortfall predicted to occur during the first half of the 21st century. The accelerator breeder offers the only practical means today of producing, or breeding, large quantities of fissile fuel from fertile materials, albeit at high cost. Studies performed over the last few years at Chalk River Laboratory and at Brookhaven National Laboratory have demonstrated that the accelerator breeder is practical, technically feasible with state-of-the-art technology, and is economically competitive with any other proposed synthetic means of fissile fuel production. This paper gives the parameters of a nearly optimized accelerator-breeder system, then discusses the development needs, and the economics and institutional problems that this breeding concept faces

    In cancer therapy using collimated beams of photons, the radiation oncologist must determine a set of beams that delivers the required dose to each point in the tumor and minimizes the risk of damage to the healthy tissue and vital organs. Currently, the oncologist determines these beams iteratively, by using a sequence of dose calculations using approximate numerical methods. In this paper, a more accurate and potentially faster approach, based on the Adjoint Monte Carlo method, is presented (authors).

    Granulosa cell tumour of the ovary in adults is a rare tumour of low malignant potential affecting middle aged peri or post menopausal patients. These tumours are often diagnosed at an early stage, due to their hormonally active nature. They, however, have unique distinguishing histologic features and behaviour of frequent and late local or systemic relapses. The diagnosis can be challenging with unusual presentations. There is high association of endometrial carcinoma. Surgery is the mainstay of management in early low risk disease, while radiotherapy and systemic platinum based chemotherapy are employed in higher stage with poor prognostic indices. Survival is good in early stage disease. Recurrent, progressive, and treatment refractory disease is not infrequent and poses management challenge. Endocrine manipulation and hormone treatment are employed in few cases with equivocal results, as reported in literature. We present a case of recurrent and treatment refractory GCT in a postmenopausal patient, managed by aromatase inhibitor Anastrozole with reasonable efficacy. (author)

    Colorectal cancer (CRC) is the third most common cancer worldwide and the fourth most frequent cause of cancer-related death in the world. CRC screening programs have been widely introduced worldwide, allowing for early detection and removal of precancerous lesions and avoiding major surgical intervention. However, not all polyps are suitable for conventional and advanced colonoscopic polypectomy. Thus, laparoscopically assisted colonoscopic polypectomy (LACP) was introduced to clinical practice as a method of choice for these polyps and adenomas. To overlook our experience in laparoscopically assisted colonoscopic polypectomies and evaluate effectiveness and quality of the procedure. A retrospective analysis of a prospectively maintained database was performed. using the Vilnius University Hospital Santariskiu Klinikos patient database for the period from 2010 to 2016, resulting in 21 cases in which LACP was performed. All procedures were performed using combined laparoscopy and videocolonoscopy techniques. Morphology of adenomas was classified according to the Paris classification during the procedure. Creation of the database was approved by the Lithuanian Bioethics committee. Twenty-two adenomas were removed from 21 patients, aged 65.33 ±8.9. There was no difference between male and female age, but occurrence of adenomas in females was 2-fold higher. The majority of removed lesions were localized in the cecum and mean size was 27.2 ±11.1 mm. The morphology of adenomas was distributed equally between 0-Is, 0-Ip, and 0-IIa, except one, which belonged to 0-III. Histological analysis revealed that tubulovillous adenoma occurrence was 1.4 times higher than tubulous adenoma. There was only one postoperative complication - bleeding from the adenoma resection site, which was managed by conservative means. One patient developed G2 adenocarcinoma at the polyp resection site and was referred for radical surgery. The LACP is a safe procedure with minimal risk to the elderly patient. Patient follow-up is essential for detection of recurrence.

    2013-11-01

    The paper starts summarizing the claims of Beer's viable systems model to identify five issues any viable organizations has to deal with in an unequivocal hierarchical structure of five interrelated systems. Then the evidence is introduced for additional issues and related viable structures of organizations, which deviate from Beer's model. These issues are: (1) the establishment and (2) evolution of an organization; (3) systems for independent top-down control (like "Six Sigma"); (4) systems for independent bottom-up correction of performance problems (like "Kaizen"), both working outside a hierarchical structure; (5) pull production systems ("Just in Time") and (6) systems for checks and balances of top-level power (like boards and shareholder meetings). Based on that an evolutionary approach to organizational cybernetics is outlined, addressing the establishment of organizations and possible courses of developments, including recent developments in quality and production engineering, as well as problems of setting and changing goal values determining organizational policies.

    The development of our societies and our economies this intimately related to electric power and this as well with the generating sources, due to the projection of world-wide growth should go associate with a strategy of growth of energy generation. Considering to the nuclear power as an option to satisfy the energy needs that a country can provide two main immediate benefits: The stabilization of prices of security of provision of electric power of the nation. The care of the environment, since the gas discharges greenhouse are almost null. At the moment nuclear energy represents economically a viable option for the capital investment, taking into account the development from technology, the policies implemented by the state and the prices of other fuels. Due to the great investment that its require for the nuclear plants are necessary to use financial tools that allow to analyze the future scenes in which ours investment can be seen affected and to value the flexibility of being able to enlarge, to postpone or to stop our project in order to have majors profits or to diminish the lost ones. This valuation of the flexibility can be obtained from the called method Real Options. By analysis of Real Options the process is understood to apply to the methodology of the Financial Options to the valuation of projects or the management of real assets. The Real Options appear in flexible plans, projects, activities or enterprise investments, like for example, to leave or to sell the investment project before concluding it, changing to their use or its technology, to prolong their life, the option to choose, one or the other capacity, among others possibilities. In this work is an example of the application of the method of Real Options in the decision to invest or to defer the investment for the construction of a nuclear plant following the behavior of the tariffs in the market or the costs of generation of other technologies with which a nuclear plant competes.

    1999-09-01

    This paper describes and analyzes the economics of a power relay system that takes advantage of recent technological advances to implement a system that is economically viable. A series of power relay systems are described and analyzed which transport power ranging from 1,250 megawatts to 5,000 megawatts, and distribute it to receiving sites at transcontinental distances. Two classes of systems are discussed—those with a single reflector and delivering all the power to a single rectenna, and a second type which has multiple reflectors and distributes it to 10 rectenna sites, sharing power among them. It is shown that when offering electricity at prices competitive to those prevalent in developed cities in the US that a low IRR is inevitable, and economic feasibility of a business is unlikely. However, when the target market is Japan where the prevalent electricity prices are much greater, that an IRR exceeding 65% is readily attainable. This is extremely attractive to potential investors, making capitalization of a venture likely. The paper shows that the capital investment required for the system can be less than 1 per installed watt, contributing less than 0.02 /KW-hr to the cost of energy provision. Since selling prices in feasible regions range from 0.18 to over 030 $/kW-hr, these costs are but a small fraction of the operating expenses. Thus a very large IRR is possible for such a business.

    Ultraconserved elements have been suggested to retainextended perfect sequence identity between the human, mouse, and ratgenomes due to essential functional properties. To investigate thenecessities of these elements in vivo, we removed four non-codingultraconserved elements (ranging in length from 222 to 731 base pairs)from the mouse genome. To maximize the likelihood of observing aphenotype, we chose to delete elements that function as enhancers in amouse transgenic assay and that are near genes that exhibit markedphenotypes both when completely inactivated in the mouse as well as whentheir expression is altered due to other genomic modifications.Remarkably, all four resulting lines of mice lacking these ultraconservedelements were viable and fertile, and failed to reveal any criticalabnormalities when assayed for a variety of phenotypes including growth,longevity, pathology and metabolism. In addition more targeted screens,informed by the abnormalities observed in mice where genes in proximityto the investigated elements had been altered, also failed to revealnotable abnormalities. These results, while not inclusive of all thepossible phenotypic impact of the deleted sequences, indicate thatextreme sequence constraint does not necessarily reflect crucialfunctions required for viability.

    Increasing commercialization of space services and the impending release of government's control of space access promise to make space ventures more attractive. Still, many investors shy away from going into the space tourism market as long as they do not feel secure that their return expectations will be met. First and foremost, attracting investors from the capital markets requires qualifying financing models. Based on earlier research on the cost of capital for space tourism, this paper gives a brief run-through of commercial, technical and financial due diligence aspects. After that, a closer look is taken at different valuation techniques as well as alternative ways of streamlining financials. Experience from earlier ventures has shown that the high cost of capital represents a significant challenge. Thus, the sophistication and professionalism of business plans and financial models needs to be very high. Special emphasis is given to the optimization of the debt-to-equity ratio over time. The different roles of equity and debt over a venture's life cycle are explained. Based on the latter, guidelines for the design of an optimized loan structure are given. These are then applied to simulating the financial performance of a typical space tourism venture over time, including the calculation of Weighted Average Cost of Capital (WACC) and Net Present Value (NPV). Based on a concluding sensitivity analysis, the lessons learned are presented. If applied properly, these will help to make space tourism economically viable.

    2017-02-01

    The liquid hydrogen demand, particularly driven by clean energy applications, will rise in the near future. As industrial large scale liquefiers will play a major role within the hydrogen supply chain, production capacity will have to increase by a multiple of today’s typical sizes. The main goal is to reduce the total cost of ownership for these plants by increasing energy efficiency with innovative and simple process designs, optimized in capital expenditure. New concepts must ensure a manageable plant complexity and flexible operability. In the phase of process development and selection, a dimensioning of key equipment for large scale liquefiers, such as turbines and compressors as well as heat exchangers, must be performed iteratively to ensure technological feasibility and maturity. Further critical aspects related to hydrogen liquefaction, e.g. fluid properties, ortho-para hydrogen conversion, and coldbox configuration, must be analysed in detail. This paper provides an overview on the approach, challenges and preliminary results in the development of efficient as well as economically viable concepts for large-scale hydrogen liquefaction.

    Concern with the threat posed by terrestrial asteroid and comet impacts has heightened as the catastrophic consequences of such events have become better appreciated. Although the probabilities of such impacts are very small, a reasonable question for debate is whether such phenomena should be taken into account in deciding policy for the management of spent fuel and high-level radioactive waste. The rate at which asteroid or comet impacts would affect areas of surface storage of radioactive waste is about the same as the estimated rate at which volcanic activity would affect the Yucca Mountain area. The Underground Retrievable Storage (URS) concept could satisfactorily reduce the risk from cosmic impact with its associated uncertainties in addition to providing other benefits described by previous authors.

    2013-01-01

    We applied conditional demand analysis (CDA) to estimate the average annual energy use of various electrical and natural gas appliances, and derived energy reductions associated with certain appliance upgrades and behaviours. The raw data came from 9773 Canadian households, and comprised annual electricity and natural gas use, and responses to >600 questions on dwelling and occupant characteristics, appliances, heating and cooling equipment, and associated behaviours. Replacing an old (>10 years) refrigerator with a new one was estimated to save 100 kW h/year; replacing an incandescent lamp with a CFL/LED lamp was estimated to save 20 kW h/year; and upgrading an old central heating system with a new one was estimated to save 2000 kW h/year. This latter effect was similar to that of reducing the number of walls exposed to the outside. Reducing the winter thermostat setpoint during occupied, waking hours was estimated to lower annual energy use by 200 kW h/°C-reduction, and lowering the thermostat setting overnight in winter relative to the setting during waking hours (night-time setback) was estimated to have a similar effect. This information may be used by policy-makers to optimize incentive programs, information campaigns, or other energy use change instruments. - Highlights: ► Conditional demand analysis (CDA) applied to data from 9773 Canadian households. ► Energy savings associated with certain appliance upgrades estimated. ► Energy savings associated with thermostat behaviours estimated. ► Policy-makers can use findings to optimize incentives and information campaigns

  1. Mitigation of Short-Lived Climate Pollutants from Residential Coal Heating and Combined Heating/Cooking Stoves: Impacts on the Cryosphere, Policy Options, and Co-benefits

    Residential solid fuel combustion for cooking, heating, and other energy services contributes to indoor and outdoor air pollution, and creates impacts on the cryosphere. Solid fuel use often occurs in colder climates and at higher elevations, where a wide range of combustion emissions can reduce reflectivity of the snow- and ice-covered surfaces, causing climatic warming. Reducing short-lived climate pollutants (SLCPs), such as black carbon (BC), could have substantial climate and health co-benefits, especially in areas where emissions influence the cryosphere. A review of existing literature and emissions estimates, conducted as part of the Warsaw Summit on BC and Other Emissions from Residential Coal Heating Stoves and Combined Cooking/Heating Stoves, found little nationally-representative data on the fuels and technologies used for heating and combined cooking/heating. The GAINS model estimates that 24 million tonnes of coal equivalent were combusted by households for space heating globally in 2010, releasing 190 kilotons (kt) BC. Emissions from combined cooking/heating are virtually unknown. Policy instruments could mitigate cryosphere-relevant emissions of SLCPs from residential heating or cooking. These include indoor air quality guidelines, stove emission limits, bans on the use of specific fuels, regulatory codes that stipulate when burning can occur, stove changeout programs, and voluntary public education campaigns. These measures are being implemented in countries such as Chile (fuelwood moisture reduction campaign, energy efficiency, heating system improvements), Mongolia (stove renovation, fuel switching), Peru (improved stove programs), Poland (district heating, local fuel bans), United States (stove emission regulation) and throughout the European Community (Ecodesign Directive). Few, if any, of these regulations are likely to reduce emissions from combined cooking/heating. This research team found no global platform to create and share model

    For more than 20 years there has been a concerted international effort toward addressing climate change. International conventions, such as the United Nations Foreign Convention on Climate Change (UNFCCC; ratified in 1994), have been established by committed nations seeking to address global climate change through the reduction of greenhouse gases emitted into the Earth's atmosphere (Global CCS Institute, 2011). Long recognised as the most crucial of the greenhouse gases to impact global warming, the majority of carbon dioxide's anthropogenic global emissions are directly related to fuel combustion of which both Australia and the Netherlands' energy production is significantly reliant. Both these nations will need to consider many opinions and make hard decisions if alternative energy options are to be implemented at the scale that is required to meet international emission targets. The decisions that are required not only need to consider the many options available but also their consequences. Along with politicians, policy developers and industry, the general public also need to be active participants in deciding which energy options, and their subsequent consequences, are acceptable for implementation at the national level. Access to balanced and factual information is essential in establishing informed opinions on the many policy options available. Past research has used several methods to measure public perceptions and opinions yet for complex issues, such as emission reduction, some of these methods have shown to be problematic.

    Van Schaik, L.; Van Kampen, E.

    2008-02-01

    This paper accompanies the seminar on the Commission's '08 climate action and renewable energy package. The seminar, and hence this paper, focuses on two of the legislative proposals that the package consists of, namely the revision of the EU Emissions Trading Scheme and the directive on the promotion of Renewable Energy. The purpose of this paper is to provide a clear overview of these two proposals. Its purpose is, furthermore, to provide the seminar with a clear focus. This is achieved by means of the inclusion of sections on flexibility in each proposal and the posing of issues for discussion. The objective is to analyse whether the market-based mechanism, as chosen policy instrument, and the way targets are set in the proposals allow for sufficient flexibility in achieving the targets. This refers to whether they can be expected to lead to cost-effective reductions, and whether the target-setting is perceived as fair and accommodating to economic growth projections. Important in this respect, is whether the proposals accommodate the emission reduction and renewable energy potential, as well as the investment capabilities of member states

  7. Prospects for public participation on nuclear risks and policy options: innovations in governance practices for sustainable development in the European Union.

    O'Connor, M; van den Hove, S

    2001-09-14

    We outline the potential participative governance and risk management in application to technological choices in the nuclear sector within the European Union (EU). Well-conducted public participation, stakeholder consultation and deliberation procedures can enhance the policy process and improve the robustness of strategies dealing with high-stakes investment and risk management challenges. Key nuclear issues now confronting EU member states are: public concern with large-scale environmental and health issues; the Chernobyl accident (and others less catastrophic) whose effect has been to erode public confidence and trust in the nuclear sector; the maturity of the nuclear plant, hence the emerging prominence of waste transportation, reprocessing and disposal issues as part of historical liability within the EU; the nuclear energy heritage of central and eastern European candidate countries to EU accession. The obligatory management of inherited technological risks and uncertainties on large temporal and geographical scales, is a novel feature of technology assessment and governance. Progress in the nuclear sector will aid the development of methodologies for technological foresight and risk governance in fields other than the nuclear alone.

    The U.S. Department of Energy (DOE) Fissile Materials Disposition Program (MD), in support of the U.S. arms-control and nonproliferation policies, has initiated a program to disposition surplus weapons-usable fissile material by making it inaccessible and unattractive for use in nuclear weapons. Weapons-usable fissile materials include plutonium, high-enriched uranium (HEU), and uranium-233 (sup 233)U. In support of this program, Oak Ridge National Laboratory led DOE's contractor efforts to identify and characterize options for the long-term storage and disposal of excess (sup 233)U. Five storage and 17 disposal options were identified and are described herein

  9. Climate change risks and adaptation options across Australian seafood supply chains – A preliminary assessment

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Climate change is already impacting the biology of the oceans and some dependent industries are in turn responding to these impacts. The development of response options for users of marine resources, such as fishers, is important in guiding adaptation efforts. However, harvesting fish is only the first step in a supply chain that delivers seafood to consumers. Impacts higher up the chain have seldom been considered in fisheries-climate research yet an understanding of these impacts and how climate risks and adaptation information are interpreted and used by stakeholders across the chain is vital for developing viable and sustainable adaptation options. We examined stakeholder perceptions of points where climate change impacts and adaptations currently occur, or may occur in the future, across the supply chains of several Australian fisheries (southern rock lobster, tropical rock lobster, prawn and aquaculture sectors (oyster, aquaculture prawn. We found that climate change impacts are well understood at the harvest stage and there is evidence of potential impacts and disruption to supply chains. Yet, there currently is no strong driver for change higher up the chain. Holistic adaptation planning along the supply chain, underpinned by targeted information and policy for the catch, processing and distribution, and marketing phases is needed. This effort is needed now, as some adaptation options have long lead times, and a delay in adaptation planning may limit future options. Given potential lead times and associated uncertainty, a risk-based approach is recommended with regard to adaptation planning for Australia’s seafood sector.

  10. Designing Viable Business Models for Living Labs

    Directory of Open Access Journals (Sweden)

    Bernhard R. Katzy

    2012-09-01

    Full Text Available Over 300 regions have integrated the concept of living labs into their economic development strategy since 2006, when the former Finnish Prime Minister Esko Aho launched the living lab innovation policy initiative during his term of European presidency. Despite motivating initial results, however, success cases of turning research into usable new products and services remain few and uncertainty remains on what living labs actually do and contribute. This practitioner-oriented article presents a business excellence model that shows processes of idea creation and team mobilization, new product development, user involvement, and entrepreneurship through which living labs deliver high-potential investment opportunities. Customers of living labs are identified as investors such as venture capitalists or industrial firms because living labs can generate revenue from them to create their own sustainable business model. The article concludes that living labs provide extensive support “lab” infrastructure and that it remains a formidable challenge to finance it, which calls for a more intensive debate.

  15. Management options for recycling radioactive scrap metals

    Energy Technology Data Exchange (ETDEWEB)

    Dehmel, J.C.; MacKinney, J.; Bartlett, J.

    1997-02-01

    The feasibility and advantages of recycling radioactive scrap metals (RSM) have yet to be assessed, given the unique technical, regulatory, safety, and cost-benefit issues that have already been raised by a concerned recycling industry. As is known, this industry has been repeatedly involved with the accidental recycling of radioactive sources and, in some cases, with costly consequences. If recycling were deemed to be a viable option, it might have to be implemented with regulatory monitoring and controls. Its implementation may have to consider various and complex issues and address the requirements and concerns of distinctly different industries. There are three basic options for the recycling of such scraps. They are: (1) recycling through the existing network of metal-scrap dealers and brokers, (2) recycling directly and only with specific steelmills, or (3) recycling through regional processing centers. Under the first option, scrap dealers and brokers would receive material from RSM generators and determine at which steelmills such scraps would be recycled. For the second option, RSM generators would deal directly with selected steelmills under specific agreements. For the third option, generators would ship scraps only to regional centers for processing and shipment to participating steelmills. This paper addresses the potential advantages of each option, identifies the types of arrangements that would need to be secured among all parties, and attempts to assess the receptivity of the recycling industry to each option.

    Taleitha O'Meara

    2013-09-01

    Full Text Available Abstract The use of lifetime annuities is one obvious candidate to deliver guaranteed income in retirement. This paper quantifies the marginal increase in income to a single male when compelled to purchase a lifetime annuity from superannuation savings, compared to the current position of voluntary annuitisation in the Australian market. It is found that significant increases in average income are possible under compulsion, with an associated decrease in the cost of the age pension. Future mortality is shown to be the key area of sensitivity. The critical importance of future age pension eligibility rules being adaptable in line with mortality changes is demonstrated.

    We study European options on the ratio of the stock price to its average and viceversa. Some of these options are traded in the Australian Stock Exchange since 1992, thus we call them Australian Asian options. For geometric averages, we obtain closed-form expressions for option prices. For arithmetic means, we use different approximations that produce very similar results.

  6. The Gel Generator option

    International Nuclear Information System (INIS)

    Boyd, R.E.

    1999-01-01

    The development of a national policy for guaranteeing an ample supply of 99m Tc to nuclear medicine, involves issues which go beyond the means by which radioactivation is achieved. Indeed, in such an exercise the pragmatic dictates of business and the sensitivities of politics must also be taken into account. Furthermore where a preference towards the nuclear reactor or the potential of cyclotrons is being questioned, the debate is incomplete if the only options that are considered are the fission-based 99 Mo generator versus the direct cyclotron production of 99m Tc. There is a third option (also neutron γ-based), an alternative to the fission 99 Mo generator, which ought not be overlooked. The application of low specific activity (n,γ) 99 Mo to a new type of generator, the Gel Generator, has been the focus of much research, particularly in Australia and more recently in China. After the initial concept had been established in the laboratory, the Australian researchers then undertook a comprehensive program of tests on the Gel Generator to assess its potential, either in the clinical laboratory or the centralised radiopharmacy, for supplying 99m Tc suitable for nuclear medicine. The outcome of this program was a clear indication that the Gel Generator innovation had the capability to provide both technical and economic advantages to the nuclear medicine industry. These advantages are described. Since that time the Gel Generator has been selected for routine use in China where it now satisfies more than 30% of the 99m Tc demand. (author)

    2001-02-01

    This report contains the model documentation and user instructions of the FAIR model (Framework to Assess International Regimes for differentiation of commitments). FAIR is an interactive - scanner-type - computer model to quantitatively explore a range of alternative climate policy options for international differentiation of future commitments and link these to targets for global climate protection. The model includes three different approaches for evaluating international commitment regimes: (1) Increasing participation: in this mode the number of parties involved and their level of commitment gradually increase according to participation and differentiation rules, such as per capita income, per capita emissions, or contribution to global warming; (2) Convergence: in this mode all parties participate in the burden-sharing regime, with emission rights converging to equal per capita levels over time; (3) Triptych: different burden sharing rules are applied for different sectors (e.g. convergence of per capita emissions in the domestic sector, efficiency and de-carbonisation targets for the industry sector and the power generation sector). The first two modes are representatives of top-down methodologies, so from global emission ceilings to regional emission budgets, whereas the triptych approach is more bottom-up in character, although it can be combined with specific emission targets (as illustrated in the case of the EU). In order to construct and evaluate global emission profiles, the FAIR model also has the mode: Scenario construction. In this mode the impacts in terms of the main climate indicators can be scanned of a constructed or well-defined global emissions profile

  8. Public opinion on water reuse options

    International Nuclear Information System (INIS)

    Bruvold, W.H.

    1988-01-01

    Public policy on waste water reuse options must be informed by public opinion because it is the public who must pay the cost of developing the option and who will be served by the option in the future. For public policy on reuse, guidance for innovative reuse is not as simple as first believed. It seems that public opinion regarding actual community reuse options is affected by the linkage of several factors, including water conservation, health protection, treatment and distribution costs, and environmental enhancement. Probability sampling was used in 7 studies to select respondents who were queried regarding their opinions on various reclaimed water uses such as ranging from cooling tower water to full domestic use. These 7 are briefly reviewed

    2008-02-01

    Hepatocellular carcinoma (HCC) is frequently diagnosed at advanced stages and has a high mortality rate. With improved survival of patients with cirrhotic liver disease and increased prevalence of chronic hepatitis C viral infections, a rise in the number of HCC cases is being reported worldwide. Early diagnosis and treatment can significantly improve the prognosis of patients with HCC. Although surgical resection is an important potentially curative therapy for liver tumors, in appropriately selected patients, liver transplantation has been shown to achieve excellent survival rates for a solid tumor. Locally ablative and locoregional therapies in the form of percutaneous ethanol injection, radiofrequency ablation, transcatheter arterial chemoembolization and transcatheter arterial radioembolization (TheraSphere) are viable options in patients with unresectable HCC. Unfortunately, the role of systemic therapy has been very limited in the treatment of these patients. Novel treatment options based on an improved understanding of the molecular pathogenesis of HCC are being explored. These targeted molecular therapies are aimed at growth factors and their receptors, intracellular signal transduction and cell cycle control. A substantial improvement in outcomes of intermediate and advanced stage HCC is expected with the advent of these targeted therapies, used in combination with surgical or locoregional therapies. Recent positive results from a large Phase III study of the receptor tyrosine kinase inhibitor, sorafenib, hold great promise in the treatment of HCC.

  10. A review on technological options of waste to energy for effective management of municipal solid waste.

    Science.gov (United States)

    Kumar, Atul; Samadder, S R

    2017-11-01

    Approximately one-fourth population across the world rely on traditional fuels (kerosene, natural gas, biomass residue, firewood, coal, animal dung, etc.) for domestic use despite significant socioeconomic and technological development. Fossil fuel reserves are being exploited at a very fast rate to meet the increasing energy demands, so there is a need to find alternative sources of energy before all the fossil fuel reserves are depleted. Waste to energy (WTE) can be considered as a potential alternative source of energy, which is economically viable and environmentally sustainable. The present study reviewed the current global scenario of WTE technological options (incineration, pyrolysis, gasification, anaerobic digestion, and landfilling with gas recovery) for effective energy recovery and the challenges faced by developed and developing countries. This review will provide a framework for evaluating WTE technological options based on case studies of developed and developing countries. Unsanitary landfilling is the most commonly practiced waste disposal option in the developing countries. However, developed countries have realised the potential of WTE technologies for effective municipal solid waste management (MSWM). This review will help the policy makers and the implementing authorities involved in MSWM to understand the current status, challenges and barriers for effective management of municipal solid waste. This review concluded WTE as a potential renewable source of energy, which will partly meet the energy demand and ensure effective MSWM. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Pawnee Nation of Oklahoma Energy Option Analyses In 2003, the Pawnee Nation leadership identified the need for the tribe to comprehensively address its energy issues. During a strategic energy planning workshop a general framework was laid out and the Pawnee Nation Energy Task Force was created to work toward further development of the tribe’s energy vision. The overarching goals of the “first steps” project were to identify the most appropriate focus for its strategic energy initiatives going forward, and to provide information necessary to take the next steps in pursuit of the “best fit” energy options. Description of Activities Performed The research team reviewed existing data pertaining to the availability of biomass (focusing on woody biomass, agricultural biomass/bio-energy crops, and methane capture), solar, wind and hydropower resources on the Pawnee-owned lands. Using these data, combined with assumptions about costs and revenue streams, the research team performed preliminary feasibility assessments for each resource category. The research team also reviewed available funding resources and made recommendations to Pawnee Nation highlighting those resources with the greatest potential for financially-viable development, both in the near-term and over a longer time horizon. Findings and Recommendations Due to a lack of financial incentives for renewable energy, particularly at the state level, combined mediocre renewable energy resources, renewable energy development opportunities are limited for Pawnee Nation. However, near-term potential exists for development of solar hot water at the gym, and an exterior wood-fired boiler system at the tribe’s main administrative building. Pawnee Nation should also explore options for developing LFGTE resources in collaboration with the City of Pawnee. Significant potential may also exist for development of bio-energy resources within the next decade. Pawnee Nation representatives should closely monitor

    International Nuclear Information System (INIS)

    1992-09-01

    Gasoline consumption by passenger cars and light trucks is a major source of air pollution. It also adds to the economy's dependence on petroleum and vulnerability to oil price shocks. Despite these environmental and other costs, called external cost, the price of gasoline, adjusted for inflation, has generally been declining since 1985, encouraging increased consumption. This paper reports that with these concerns in mind, the Chairman, Subcommittee on Environment, House Committee on Science, Space, and Technology, requested that GAO assess policy options for addressing the external costs of gasoline consumption. To do this, GAO identified six major policy options and evaluated whether they addressed several relevant objectives, including economic growth, environmental quality, equity, petroleum conservation, visibility of costs, energy security, traffic congestion, competitiveness, and administrative feasibility

    2013-01-01

    Different strategies and motivations in different countries have led to diverse options. In Europe the SNETP (Sustainable Nuclear Energy Technology Platform) has the objective of developing R&D supporting GEN-II (present) and GEN-III nuclear systems under development; allowing sustainability and minimisation of waste burden, promoting advanced Gen-IV Fast Reactors; and accounting for a Nuclear Cogeneration Industrial Initiative. A remarkable initiative in the USA has been the promotion of small modular reactors (SMRs) – at less than 300 MWe in capacity, much smaller than typical reactors – which can be an ideal choice for (remote) areas which cannot support a larger reactor. Compact scalable design offers a host of potential safety, construction and economic benefits. More “upbeat” strategies are expected in other areas of the world where significant increase in nuclear energy demand is predicted in the next decades. If this growth materialises, future fuel cycles characteristics, feasibility and acceptability will be crucial. This paper will discuss different scenarios for future fuel cycles, resources optimisation and/or waste minimization, the range from full fast reactor deployment to phase-out, management of spent nuclear fuel and the significant potential benefits of advanced cycles. The next 45 years will be dominated by deployment of standard large or medium size plants operating for 60 years. Available resources do allow it. However, fuel cycle will be a growing and most challenging issue and early assessments will be needed for public acceptance and policy decisions.

Based on the request of Pawnee Nation’s Energy Task Force the research team, consisting Tribal personnel and Summit Blue Consulting, focused on a review of renewable energy resource development potential, funding sources and utility organizational along with energy savings options. Elements of the energy demand forecasting and characterization and demand side options review remained in the scope of work, but were only addressed at a high level. Description of Activities Performed Renewable Energy Resource Development Potential The research team reviewed existing data pertaining to the availability of biomass (focusing on woody biomass, agricultural biomass/bio-energy crops, and methane capture), solar, wind and hydropower resources on the Pawnee-owned lands. Using these data, combined with assumptions about costs and revenue streams, the research team performed preliminary feasibility assessments for each resource category. The research team also reviewed available funding resources and made recommendations to Pawnee Nation highlighting those resources with the greatest potential for financially-viable development, both in the near-term and over a longer time horizon. Energy Efficiency Options While this was not a major focus of the project, the research team highlighted common strategies for reducing energy use in buildings. The team also discussed the benefits of adopting a building energy code and

  19. Corporate strategy and viable future land use: Planning for closure from the outset of mining

    International Nuclear Information System (INIS)

    Warhurst, A.

    2000-01-01

    This paper provides an overview of the environmental impact of mining on viable future land use and underlines the imperative of improved environmental management and closure planning. It argues that pollution prevention, through planning for closure, can lead to cost-effective strategies for sustainable minerals development and viable future land use. This seems to be most true for greenfield sites since, generally, the earlier closure planning and pollution prevention is built into a project, the more cost-effective and environmentally benign closure will be. Further, for greenfield sites, pollution prevention techniques can be employed from the outset, at the stages of exploration and mine development, and then monitored and improved through the operation stage to closure, and can be kept in place to manage future land use. The paper discusses how global changes in the industry, following the liberalisation of investment regimes, and mergers and strategic alliances between key firms, has, by virtue of the diffusion of new technology, led to further opportunities to prevent pollution and optimise future land use through planning for closure from the outset. The objectives and components of closure plans are also reviewed as the paper draws on case studies to highlight some of the possible constraints and challenges to pollution prevention that may be faced at the level of both public policy and corporate strategy. The article concludes by suggesting a forward-looking approach to integrated environmental management and viable future land-use planning based on a dynamic model for environmental management.

    Since this report was originally issued in 2001, several options proposed for increasing double-shell tank (DST) storage space were implemented or are in the process of implementation. Changes to the single-shell tank (SST) waste retrieval schedule, completion of DST space saving options, and the DST space saving options in progress have delayed the projected shortfall of DST storage space from the 2007-2011 to the 2018-2025 timeframe (ORP-11242, River Protection Project System Plan). This report reevaluates options from Rev. 0 and includes evaluations of new options for alleviating projected restrictions on SST waste retrieval beginning in 2018 because of the lack of DST storage space.

    2006-01-01

    There is renewed interest in distributed generation (DG). This paper reviews the different technological options available for DG, their current status and evaluates them based on the cost of generation and future potential in India. The non-renewable options considered are internal combustion engines fuelled by diesel, natural gas and microturbines and fuel cells fired by natural gas. The renewable technologies considered are wind, solar photovoltaic, biomass gasification and bagasse cogeneration. The cost of generation is dependent on the load factor and the discount rate. Gas engines and Bagasse based cogeneration are found to be the most cost effective DG options while wind and biomass gasifier fired engines are viable under certain conditions. PEM Fuel cells and micro turbines based on natural gas need a few demonstrations projects and cost reductions before becoming viable. A strategy involving pilot projects, tracking of costs and dissemination of information is likely to result in DG meeting 10% of India's power needs by 2012

  4. Fusion as an energy option

    International Nuclear Information System (INIS)

    Steiner, D.

    1976-01-01

    The environmental issues, alternative fusion fuels, the economic potential, and the time scale of fusion power are assessed. It is common for the advocate of a long-term energy source to claim his source (fission, fusion, solar, etc.) as the ultimate solution to man's energy needs. The author does not believe that such a stance will lead to a rational energy policy. Dr. Steiner encourages a long-term energy policy that has as its goal the development of fission breeders, fusion, and solar energy--not be totally reliant on a single source. He does advocate vigorous funding for fusion, not because it is a guarantee for ''clean, limitless, and cheap power,'' but because it may provide an important energy option for the next century

    Each of the five biotic approaches introduced in Chapter 2 is applicable to some extent in the US. Taking US land-use characteristics into account, a menu of policy options tailored to US carbon storage opportunities is presented. Several of the options are capable of significantly reducing net US carbon emissions; several offer corollary benefits in areas other than global warming mitigation. The time frame and costs of the different options vary widely, although in most cases some level of implementation appears economically justified even without considering global warming. The approach, projected costs, and advantages of seven different policy options are profiled

    The development of our societies and our economies this intimately related to electric power and this as well with the generating sources, due to the projection of world-wide growth should go associate with a strategy of growth of energy generation. Considering to the nuclear power as an option to satisfy the energy needs that a country can provide two main immediate benefits: The stabilization of prices of security of provision of electric power of the nation. The care of the environment, since the gas discharges greenhouse are almost null. At the moment nuclear energy represents economically a viable option for the capital investment, taking into account the development from technology, the policies implemented by the state and the prices of other fuels. Due to the great investment that its require for the nuclear plants are necessary to use financial tools that allow to analyze the future scenes in which ours investment can be seen affected and to value the flexibility of being able to enlarge, to postpone or to stop our project in order to have majors profits or to diminish the lost ones. This valuation of the flexibility can be obtained from the called method Real Options. By analysis of Real Options the process is understood to apply to the methodology of the Financial Options to the valuation of projects or the management of real assets. The Real Options appear in flexible plans, projects, activities or enterprise investments, like for example, to leave or to sell the investment project before concluding it, changing to their use or its technology, to prolong their life, the option to choose, one or the other capacity, among others possibilities. In this work is an example of the application of the method of Real Options in the decision to invest or to defer the investment for the construction of a nuclear plant following the behavior of the tariffs in the market or the costs of generation of other technologies with which a nuclear plant competes.

    2011-01-01

    The energy industry, accounts for the largest portion of CO 2 emissions, is facing the issue of compliance with the national clean energy policy. The methodology for evaluating the energy mix policy is crucial because of the characteristics of lead time embedded with the power generation facilities investment and the uncertainty of future electricity demand. In this paper, a modified binomial model based on sequential compound options, which may account for the lead time and uncertainty as a whole is established, and a numerical example on evaluating the optional strategies and the strategic value of the cleaner energy policy is also presented. It is found that the optimal decision at some nodes in the binomial tree is path dependent, which is different from the standard sequential compound option model with lead time or time lag concept. The proposed modified binomial sequential compound real options model can be generalized and extensively applied to solve the general decision problems that deal with the long lead time of many government policies as well as capital intensive investments. - Highlights: → Introducing a flexible strategic management approach for government policy making. → Developing a modified binomial real options model based on sequential compound options. → Proposing an innovative model for managing the long term policy with lead time. → Applying to evaluate the options of various scenarios of cleaner energy strategies.

  13. Value of an option to purchase electric power. The case of uncertain consumption

    International Nuclear Information System (INIS)

    Bhanot, Karan

    2002-01-01

    Large manufacturers and corporations often purchase options on power to protect themselves against unanticipated price increases. This paper analyzes the impact of uncertainty in power consumption by a corporation on the value of an option to purchase electric power. Because there is no economically viable method to store power, these options are exercised to satisfy immediate consumption needs only. The amount exercised may differ from the maximum amount contracted, which in turn alters the payoffs that accrue to the option contract. We apply a Monte Carlo methodology to show that 'consumption uncertainty' may substantively lower the price of an option contract under different conditions

  14. Evaluating State Options for Reducing Medicaid Churning

    2015-01-01

    Medicaid churning - the constant exit and re-entry of beneficiaries as their eligibility changes - has long been a problem for both Medicaid administrators and recipients. Churning will continue under the Affordable Care Act, because despite new federal rules, Medicaid eligibility will continue to be based on current monthly income. We developed a longitudinal simulation model to evaluate four policy options for modifying or extending Medicaid eligibility to reduce churning. The simulations suggest that two options, extending Medicaid eligibility either to the end of a calendar year or for twelve months after enrollment, would be far more effective in reducing churning than the other options of a three-month extension or eligibility based on projected annual income. States should consider implementation of the option that best balances costs, including both administration and services, with improved health of Medicaid enrollees. PMID:26153313

    Smaldino, Paul E; Richerson, Peter J

    2012-01-01

    Most research on decision making has focused on how human or animal decision makers choose between two or more options, posed in advance by the researchers. The mechanisms by which options are generated for most decisions, however, are not well understood. Models of sequential search have examined the trade-off between continued exploration and choosing one's current best option, but still cannot explain the processes by which new options are generated. We argue that understanding the origins of options is a crucial but untapped area for decision making research. We explore a number of factors which influence the generation of options, which fall broadly into two categories: psycho-biological and socio-cultural. The former category includes factors such as perceptual biases and associative memory networks. The latter category relies on the incredible human capacity for culture and social learning, which doubtless shape not only our choices but the options available for choice. Our intention is to start a discussion that brings us closer toward understanding the origins of options.

    1990-01-01

    The delayed decisions on nuclear fuel reprocessing strategies in the USA and other countries have forced the development of new long-term irradiated fuel storage techniques, to allow a larger volume of fuel to be held on the nuclear station site after removal from the reactor. The nuclear power industry has responded to the challenge by developing several viable options for long-term onsite storage, which can be employed individually or in tandem. They are: densification of storage in the existing spent fuel pool; building another fuel pool facility at the plant site; onsite cask park, and on site vault clusters. Desirable attributes of a storage option are: Safety: minimise the number of fuel handling steps; Economy: minimise total installed, and O and M cost; Security: protection from anti-nuclear protesters; Site adaptability: available site space, earthquake characteristics of the region and so on; Non-intrusiveness: minimise required modifications to existing plant systems; Modularisation: afford the option to adapt a modular approach for staged capital outlays; and Maturity: extent of industry experience with the technology. A critical appraisal is made of each of the four aforementioned storage options in the light of these criteria. (2 figures, 1 table, 4 references) (Author)

    When advising farmers on how to control Johne's disease in an infected herd, one of the main recommendations is to avoid feeding waste milk to calves and instead feed calf milk replacer (CMR). This advice is based on the assumption that CMR is free of viable Mycobacterium avium ssp. paratuberculosis (MAP) cells, an assumption that has not previously been challenged. We tested commercial CMR products (n = 83) obtained from dairy farms around the United States by the peptide-mediated magnetic separation (PMS)-phage assay, PMS followed by liquid culture (PMS-culture), and direct IS900 quantitative PCR (qPCR). Conventional microbiological analyses for total mesophilic bacterial counts, coliforms, Salmonella, coagulase-negative staphylococci, streptococci, nonhemolytic Corynebacterium spp., and Bacillus spp. were also performed to assess the overall microbiological quality of the CMR. Twenty-six (31.3%) of the 83 CMR samples showed evidence of the presence of MAP. Seventeen (20.5%) tested positive for viable MAP by the PMS-phage assay, with plaque counts ranging from 6 to 1,212 pfu/50 mL of reconstituted CMR (average 248.5 pfu/50 mL). Twelve (14.5%) CMR samples tested positive for viable MAP by PMS-culture; isolates from all 12 of these samples were subsequently confirmed by whole-genome sequencing to be different cattle strains of MAP. Seven (8.4%) CMR samples tested positive for MAP DNA by IS900 qPCR. Four CMR samples tested positive by both PMS-based tests and 5 CMR samples tested positive by IS900 qPCR plus one or other of the PMS-based tests, but only one CMR sample tested positive by all 3 MAP detection tests applied. All conventional microbiology results were within current standards for whole milk powders. A significant association existed between higher total bacterial counts and presence of viable MAP indicated by either of the PMS-based assays. This represents the first published report of the isolation of viable MAP from CMR. Our findings raise concerns

  4. Polish Toxic Currency Options

    Directory of Open Access Journals (Sweden)

    Waldemar Gontarski

    2009-06-01

    Full Text Available Toxic currency options are defined on the basis of the opposition to the nature (essence of an option contract, which is justified in terms of norms founded on the general law clause of characteristics (nature of a relation (which represents an independent premise for imposing restrictions on the freedom of contracts. So-understood toxic currency options are unlawful. Indeed they contravene iuris cogentis regulations. These include for instance option contracts, which are concluded with a bank, if the bank has not informed about option risk before concluding the contract; or the barrier options, which focus only on the protection of bank’s interests. Therefore, such options may appear to be invalid. Therefore, performing contracts for toxic currency options may be qualified as a criminal mismanagement. For the sake of security, the manager should then take into consideration filing a claim for stating invalidity (which can be made in a court verdict. At the same time, if the supervisory board member in a commercial company, who can also be a subject to mismanagement offences, commits an omission involving lack of reaction (for example, if he/she fails to notify of the suspected offence committed by the management board members acting to the company’s detriment when the management board makes the company conclude option contracts which are charged with absolute invalidity the supervisory board member so acting may be considered to act to the company’s detriment. In the most recent Polish jurisprudence and judicature the standard of a “good host” is treated to be the last resort for determining whether the manager’s powers resulting from criminal regulations were performed. The manager of the exporter should not, as a rule, issue any options. Issuing options always means assuming an obligation. In the case of currency put options it is an absolute obligation to purchase a given amount in euro at exchange rate set in advance. On the

    2005-01-01

    This resource options report (ROR) fulfils regulatory requirements in British Columbia's two-year resource planning process. It identifies a wide range of resources and technologies that could be used to meet BC Hydro's future electricity demand. As such, it facilitates a transparent public review of resource options which include both supply-side and demand-side options. The resource options that will be used in the 2005 integrated electricity plan (IEP) were characterized. This ROR also documents where there is a general agreement or disagreement on the resource type characterization, based on the First Nations and Stakeholder engagement. BC Hydro used current information to provide realistic ranges on volume and cost to characterize environmental and social attributes. The BC Hydro system was modelled to assess the benefit and cost of various resource options. The information resulting from this ROR and IEP will help in making decisions on how to structure competitive acquisition calls and to determine the level of transmission services needed to advance certain BC Hydro projects. The IEP forecasts the nature and quantity of domestic resources required over the next 20 years. A strategic direction on how those needs will be met has been created to guide the management of BC Hydro's energy resources. Supply-side options include near-commercial technologies such as energy storage, ocean waves, tidal, fuel cells and integrated coal gasification combined cycle technology. Supply-side options also include natural gas, coal, biomass, geothermal, wind, and hydro. 120 refs., 39 tabs., 21 figs., 6 appendices

  6. Aluminum industry options paper

    International Nuclear Information System (INIS)

    1999-10-01

    In 1990, Canada's producers of aluminum (third largest in the world) emitted 10 million tonnes of carbon dioxide and equivalent, corresponding to 6.4 tonnes of greenhouse gas intensity per tonne of aluminum. In 2000, the projection is that on a business-as-usual (BAU) basis Canadian producers now producing 60 per cent more aluminum than in 1990, will emit 10.7 million tonnes of carbon dioxide and equivalent, corresponding to a GHG intensity of 4.2 tonnes per tonne of aluminum. This improvement is due to production being based largely on hydro-electricity, and partly because in general, Canadian plants are modern, with technology that is relatively GHG-friendly. The Aluminum Association of Canada estimates that based on anticipated production, and under a BAU scenario, GHG emissions from aluminum production will rise by 18 per cent by 2010 and by 30 per cent by 2020. GHG emissions could be reduced below the BAU forecast first, by new control and monitoring systems at some operations at a cost of $4.5 to 7.5 million per smelter. These systems could reduce carbon dioxide equivalent emissions by 0.8 million tonnes per year. A second alternative would require installation of breaker feeders which would further reduce perfluorocarbon (PFC) emissions by 0.9 million tonnes of carbon dioxide equivalent. Cost of the breakers feeders would be in the order of $200 million per smelter. The third option calls for the the shutting down of some of the smelters with older technology by 2015. In this scenario GHG emissions would be reduced by 2010 by 0.8 million tonnes per year of carbon dioxide equivalent. However, the cost in this case would be about $1.36 billion. The industry would support measures that would encourage the first two sets of actions, which would produce GHG emissions from aluminum production in Canada of about 10.2 million tonnes per year of carbon dioxide equivalent, or about two per cent above 1990 levels with double the aluminum production of 1990.

  9. Expensing options solves nothing.

    Science.gov (United States)

    Sahlman, William A

    2002-12-01

    The use of stock options for executive compensation has become a lightning rod for public anger, and it's easy to see why. Many top executives grew hugely rich on the back of the gains they made on their options, profits they've been able to keep even as the value they were supposed to create disappeared. The supposed scam works like this: Current accounting regulations let companies ignore the cost of option grants on their income statements, so they can award valuable option packages without affecting reported earnings. Not charging the cost of the grants supposedly leads to overstated earnings, which purportedly translate into unrealistically high share prices, permitting top executives to realize big gains when they exercise their options. If an accounting anomaly is the problem, then the solution seems obvious: Write off executive share options against the current year's revenues. The trouble is, Sahlman writes, expensing option grants won't give us a more accurate view of earnings, won't add any information not already included in the financial statements, and won't even lead to equal treatment of different forms of executive pay. Far worse, expensing evades the real issue, which is whether compensation (options and other-wise) does what it's supposed to do--namely, help a company recruit, retain, and provide the right people with appropriate performance incentives. Any performance-based compensation system has the potential to encourage cheating. Only ethical management, sensible governance, adequate internal control systems, and comprehensive disclosure will save the investor from disaster. If, Sahlman warns, we pass laws that require the expensing of options, thinking that's fixed the fundamental flaws in corporate America's accounting, we will have missed a golden opportunity to focus on the much more extensive defects in the present system.

We show theoretically that this result is overturned when investors face frictions. Early option exercise can be optimal when...... it reduces short-sale costs, transaction costs, or funding costs. We provide consistent empirical evidence, documenting billions of dollars of early exercise for options and convertible bonds using unique data on actual exercise decisions and frictions.

We show theoretically that this result is overturned when investors face frictions. Early option exercise can be optimal when...... it reduces short-sale costs, transaction costs, or funding costs. We provide consistent empirical evidence, documenting billions of dollars of early exercise for options and convertible bonds using unique data on actual exercise decisions and frictions. Our model can explain as much as 98% of early exercises...

    This paper addresses options for dealing with human intrusion in terms of performance requirements and repository siting and design requirements. Options are presented, along with the advantages and disadvantages of certain approaches. At the conclusion, a conceptual approach is offered emphasizing both the minimization of subjective judgements concerning future human activity, and specification of repository requirements to minimize the likelihood of human intrusion and any resulting, harmful effects should intrusion occur

    The objectives were to evaluate a technique, outcome and complications following anterior greater trochanteric with gluteus medius muscle pedicle bone graft (AMG) procedure in the treatment of adolescent and active adult hip disorders. 20 patients (20 hips) with a mean age of 22.7 ± 15.6 (range 10.0-63.5) years who had undergone AMG and been followed up more than 12 months postoperative were retrospectively enrolled in our study. The AMG procedure was performed in conjunction with subcapital osteotomy for slipped capital femoral epiphysis in 12 and open reduction for fracture/dislocation in 8 hips. At the most recent evaluation, patient functional status was rated by the Harris Hip Score (HHS) and radiographic changes were graded according to Tönnis criteria. Complications were defined as Tönnis grade >2 or hip requiring further surgery. Univariate analysis was used to explore factors associated with complications. Spearman's rank correlation coefficient was calculated between HHS and Tönnis grading. At mean follow-up of 4.4 ± 2.6 (range 1.1-9.5) years, mean HHS was 87.4. Tönnis grading was rated as 0 in 10 hips, 1 in 5 hips, 2 in 2 hips, and 3 in 3 hips. Avascular necrosis of the femoral head as a complication developed in 3 hips (15%). Clinical parameters including age at surgery, duration of follow-up and diagnosis were not significantly associated with postoperative complications. A negative correlation between HHS and Tönnis grade was shown by Spearman's rank correlation (rs = -0.49, p = 0.03). The AMG can be safely recommended as an adjunct bone graft procedure when performing anterior open reduction of adolescent and active adult hip disorders.

    Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited renal disease, with 50-75% of these patients requiring renal replacement therapy (RRT). The outcome of peritoneal dialysis (PD) in ADPKD with end-disease renal disease (ESRD) is not clearly defined, more so in developing countries. We conducted a retrospective analysis of the outcomes and economics of PD in these ESRD patients and compared them with other causes of ESRD on PD. Data were reviewed of all the PD patients who were followed-up at our institute from January 2007 to December 2011. The inclusion criteria were ADPKD patients who chose PD as the dialysis modality (Group 1), while age and gender-matched ESRD (other than ADPKD) patients who were started on PD during the same period were considered as the other group (Group 2). A total of 26 ADPKD patients underwent PD with an average size of kidneys among ADPKD ESRD patients of 15.2 + 2.1 cm. The overall peritonitis rates were similar among the compared groups. The median survival for the first peritonitis episodes were 1.2 and 1.8 years (95% confidence interval 0.82-1.91) for the control and ADPKD groups, respectively. The overall patient survival was 22 among PKD while five patients died among the control group. Among PKD, one patient died due to intra-cerebral bleed while one patient had severe cyst hemorrhage and infection, while three others had peritonitis and sepsis. Hernia was observed in four ADPKD patients, once on PD that was surgically corrected and PD was resumed in all. Two patients lost the catheter due to peritonitis while one patient had membrane failure while one underwent surgical exploration due to diverticulosis. PD treatment was not prevented by voluminous kidneys in any of these patients and no patient ceased PD treatment due to insufficient peritoneal space. Besides this, the cost on PD was much less as compared with that on hemodialysis (HD). PD is a reasonable mode of RRT among ADPKD, where HD is not possible or contraindicated with lesser risks to bleeding and infections, and the cost benefit favoring PD in general.

    Full Text Available Abstract Background Households with fixed-line telephones have decreased while mobile (cell phone ownership has increased. We therefore sought to examine the feasibility of recruiting young women for a national health survey through random digit dialling mobile phones. Methods Two samples of women aged 18 to 39 years were surveyed by random digit dialling fixed and mobile numbers. We compared participation rates and responses to a questionnaire between women surveyed by each contact method. Results After dialling 5,390 fixed-lines and 3,697 mobile numbers, 140 and 128 women were recruited respectively. Among women contacted and found to be eligible, participation rates were 74% for fixed-lines and 88% for mobiles. Taking into account calls to numbers where eligibility was unknown (e.g. unanswered calls the estimated response rates were 54% and 45% respectively. Of women contacted by fixed-line, 97% reported having a mobile while 61% of those contacted by mobile reported having a fixed-line at home. After adjusting for age, there were no significant differences between mobile-only and fixed-line responders with respect to education, residence, and various health behaviours; however compared to those with fixed-lines, mobile-only women were more likely to identify as Indigenous (OR 4.99, 95%CI 1.52-16.34 and less likely to live at home with their parents (OR 0.09, 95%CI 0.03-0.29. Conclusions Random digit dialling mobile phones to conduct a health survey in young Australian women is feasible, gives a comparable response rate and a more representative sample than dialling fixed-lines only. Telephone surveys of young women should include mobile dialling.

    The raw starch digesting type of amylase (RSDA) presents greater opportunities for process efficiency at cheaper cost and shorter time compared to regular amylases. Chemical modification is a simple and rapid method toward their stabilization for a wider application. RSDA from Aspergillus carbonarius was modified with either phthalic anhydride (PA) or chitosan. Activity retention was 87.3% for PA-modified and 80.9% for chitosan-modified RSDA. Optimum pH shifted from 5 to 7 after PA-modification. Optimum temperature changed from 30°C (native) to 30-40°C and 60°C for PA-modified and chitosan-modified, respectively. Activation energy (kJmol -1 ) for hydrolysis was 13.5, 12.7, and 10.2 while the activation energy for thermal denaturation was 32.8, 80.3, 81.9 for free, PA-modified and chitosan-modified, respectively. The specificity constants (V max /K m ) were 73.2 for PA-modified, 63.1 for chitosan-modified and 77.1 for native RSDA. The half-life (h) of the RSDA at 80°C was increased from 6.1 to 25.7 for the PA-modified and 138.6 for the chitosan derivative. Modification also led to increase in D value, activation enthalpy and Gibbs free energy of enzyme deactivation. Fluorescence spectra showed that center of spectral mass decreased for the PA-modified RSDA but increased for chitosan modified RSDA. Copyright © 2017 Elsevier B.V. All rights reserved.

    The purpose of the research described in this report was to consider the options for future UK radioactive waste categorisation, to evaluate the advantages and disadvantages of each option and, as a result, to identify any which might be viable practical alternatives to the current arrangements. The review process included meetings with large and small waste producers, a wider consultation exercise using a questionnaire, a presentation to RWMAC, and discussion with representatives of the UK regulators. These consultations provided the basis for the formulation and evaluation of a number of alternative waste categorisation schemes. (UK)

  2. Real Options Analysis of Electricity Investments

    Heggedal, Ane Marte

    2012-07-01

    This thesis utilizes real options analysis for evaluating investment opportunities in the electricity sector. It also formally tests how investors in hydropower plants have included uncertainty when considering their investment opportunities. The real options method applies financial options theory to quantify the value of management flexibility and is chosen due to three important characteristics of investments in the electricity sector. First; the investment is completely or partially irreversible, second; the investor can choose when to invest in the facility, and third; there is uncertainty in several factors affecting the cash flows of the investments. Factors of uncertainty include the development of electricity prices, policies, technological advances, and macroeconomics measures.Four papers are included in this thesis. Paper 1, Upgrading hydropower plants with storage: Timing and capacity choice, presents a valuation framework for deciding when to upgrade an existing hydropower plant and which capacity to choose. The second paper, Transmission capacity between Norway and Germany: A real options analysis, sheds light on when two electricity markets, in this case Norway and Germany, should be connected through a sub sea cable. The investor can choose when to invest and the capacity of the cable, and may also choose to invest sequentially. Paper 3, Optimal timing and capacity choice for pumped hydropower storage, investigates when investment in a pumped hydropower plant with storage should be undertaken and what the capacity of the facility should be. Whereas the three first papers investigate investment opportunities, Paper 4, Uncertain climate policy decisions and investment timing: Evidence from small hydropower plants, studies when investors in small hydropower plants chose to invest. The analyses disclose whether the net present value approach or the real options method best describe the investment decisions made by the investors. Viewing investment

    This study performs a cost and schedule analysis of three Nevada Transportation options that support waste receipt at the repository. Based on the U.S. Department of Energy preference for rail transportation in Nevada (given in the Final Environmental Impact Statement), it has been assumed that a branch rail line would be constructed to support waste receipt at the repository. However, due to potential funding constraints, it is uncertain when rail will be available. The three Nevada Transportation options have been developed to meet a varying degree of requirements for transportation and to provide cost variations used in meeting the funding constraints given in the Technical Direction Letter guidelines for this study. The options include combinations of legal-weight truck, heavy-haul truck, and rail. Option 1 uses a branch rail line that would support initial waste receipt at the repository in 2010. Rail transportation would be the primary mode, supplemented by legal weight trucks. This option provides the highest level of confidence in cost and schedule, lowest public visibility, greatest public acceptability, lowest public dose, and is the recommended option for support of waste receipt. The completion of rail by 2010 will require spending approximately $800 million prior to 2010. Option 2 uses a phased rail approach to address a constrained funding scenario. To meet funding constraints, Option 2 uses a phased approach to delay high cost activities (final design and construction) until after initial waste receipt in 2010. By doing this, approximately 95 percent of the cost associated with completion of a branch rail line is deferred until after 2010. To support waste receipt until a branch rail line is constructed in Nevada, additional legal-weight truck shipments and heavy-haul truck shipments (on a limited basis for naval spent nuclear fuel) would be used to meet the same initial waste receipt rates as in Option 1. Use of heavy-haul shipments in the absence

  4. Geothermal power, policy, and design: Using levelized cost of energy and sensitivity analysis to target improved policy incentives for the U.S. geothermal market

    Science.gov (United States)

    Richard, Christopher L.

    At the core of the geothermal industry is a need to identify how policy incentives can better be applied for optimal return. Literature from Bloomquist (1999), Doris et al. (2009), and McIlveen (2011) suggest that a more tailored approach to crafting geothermal policy is warranted. In this research the guiding theory is based on those suggestions and is structured to represent a policy analysis approach using analytical methods. The methods being used are focus on qualitative and quantitative results. To address the qualitative sections of this research an extensive review of contemporary literature is used to identify the frequency of use for specific barriers, and is followed upon with an industry survey to determine existing gaps. As a result there is support for certain barriers and justification for expanding those barriers found within the literature. This method of inquiry is an initial point for structuring modeling tools to further quantify the research results as part of the theoretical framework. Analytical modeling utilizes the levelized cost of energy as a foundation for comparative assessment of policy incentives. Model parameters use assumptions to draw conclusions from literature and survey results to reflect unique attributes held by geothermal power technologies. Further testing by policy option provides an opportunity to assess the sensitivity of each variable with respect to applied policy. Master limited partnerships, feed in tariffs, RD&D, and categorical exclusions all result as viable options for mitigating specific barriers associated to developing geothermal power. The results show reductions of levelized cost based upon the model's exclusive parameters. These results are also compared to contemporary policy options highlighting the need for tailored policy, as discussed by Bloomquist (1999), Doris et al. (2009), and McIlveen (2011). It is the intent of this research to provide the reader with a descriptive understanding of the role of

    Due to recent SARS related issues (Science 300 (5624) 1394; Nature 423 (2003) 240; Science 300 (5627) 1966), the development of reliable airborne virus monitoring procedures has become galvanized by an exceptional sense of urgency and is presently in a high demand (In: Cox, C.S., Wathers, C.M. (Eds.), Bioaerosols Handbook, Lewis Publishers, Boca Raton, FL, 1995, pp. 247-267). Based on engineering control method (Aerosol Science and Technology 31 (1999) 249; 35 (2001) 852), which was previously applied to the removal of particles from gas carriers, a new personal bioaerosol sampler has been developed. Contaminated air is bubbled through porous medium submerged into liquid and subsequently split into multitude of very small bubbles. The particulates are scavenged by these bubbles, and, thus, effectively removed. The current study explores its feasibility for monitoring of viable airborne SARS virus. It was found that the natural decay of such virus in the collection fluid was around 0.75 and 1.76 lg during 2 and 4 h of continuous operation, respectively. Theoretical microbial recovery rates of higher than 55 and 19% were calculated for 1 and 2 h of operation, respectively. Thus, the new sampling method of direct non-violent collection of viable airborne SARS virus into the appropriate liquid environment was found suitable for monitoring of such stress sensitive virus.

    Full Text Available De los trabajos presentados acerca de las formas cocoides de Helicobacter pylori se deduce una controversia mucho mayor que la resultante del mero estudio clínico de este microorganismo. Parece claro que existe una conversión tanto in vivo como in vitro de las formas espirales a las formas cocoides inducida por varios motivos, como cultivos prolongados, estrés físico y químico, y agentes antimicrobianos. En esta revisión repasamos los puntos de vista que han dividido a investigadores de esta área en dos grupos bien definidos: Los que consideran a estas formas cocoides como un producto no viable de degeneración celular y los que piensan que estas formas son estructuras viables,durmientes o de resistencia frente a condiciones ambientales adversas. Esta discrepancia conlleva a que interrogantes sobre la relación entre la transmisión de la enfermedad y estas formas cocoides permanezcan sin respuesta todavía.

    Full Text Available Probiotics are live microorganisms that provide health benefits to humans. Some lactic acid bacteria (LAB are probiotic organisms used in the production of fermented foods, such as yogurt, cheese, and pickles. Given their widespread consumption, it is important to understand the physiological state of LAB in foods such as yogurt. However, this analysis is complicated, as it is difficult to separate the LAB from milk components such as solid curds, which prevent cell separation by dilution or centrifugation. In this study, we successfully separated viable LAB from yogurt by density gradient centrifugation. The recovery rate was >90 %, and separation was performed until the stationary phase. Recovered cells were observable by microscopy, meaning that morphological changes and cell viability could be directly detected at the single-cell level. The results indicate that viable LAB can be easily purified from fermented milk. We expect that this method will be a useful tool for the analysis of various aspects of probiotic cells, including their enzyme activity and protein expression. Keywords: Food analysis, Microbiology

  9. Disposal options for radioactive waste

    International Nuclear Information System (INIS)

    Olivier, J.P.

    1991-01-01

    On the basis of the radionuclide composition and the relative toxicity of radioactive wastes, a range of different options are available for their disposal. Practically all disposal options rely on confinement of radioactive materials and isolation from the biosphere. Dilution and dispersion into the environment are only used for slightly contaminated gaseous and liquid effluents produced during the routine operation of nuclear facilities, such as power plants. For the bulk of solid radioactive waste, whatever the contamination level and decay of radiotoxicity with time are, isolation from the biosphere is the objective of waste disposal policies. The paper describes disposal approaches and the various techniques used in this respect, such as shallow land burial with minimum engineered barriers, engineered facilities built at/near the surface, rock cavities at great depth and finally deep geologic repositories for long-lived waste. The concept of disposing long-lived waste into seabed sediment layers is also discussed, as well as more remote possibilities, such as disposal in outer space or transmutation. For each of these disposal methods, the measures to be adopted at institutional level to reinforce technical isolation concepts are described. To the extent possible, some comments are made with regard to the applicability of such disposal methods to other hazardous wastes. (au)

  3. Evaluating sub-national building-energy efficiency policy options under uncertainty: Efficient sensitivity testing of alternative climate, technological, and socioeconomic futures in a regional integrated-assessment model

    Improving the energy efficiency of building stock, commercial equipment, and household appliances can have a major positive impact on energy use, carbon emissions, and building services. Sub-national regions such as the U.S. states wish to increase energy efficiency, reduce carbon emissions, or adapt to climate change. Evaluating sub-national policies to reduce energy use and emissions is difficult because of the large uncertainties in socioeconomic factors, technology performance and cost, and energy and climate policies. Climate change itself may undercut such policies. However, assessing all of the uncertainties of large-scale energy and climate models by performing thousands of model runs can be a significant modeling effort with its accompanying computational burden. By applying fractional–factorial methods to the GCAM-USA 50-state integrated-assessment model in the context of a particular policy question, this paper demonstrates how a decision-focused sensitivity analysis strategy can greatly reduce computational burden in the presence of uncertainty and reveal the important drivers for decisions and more detailed uncertainty analysis. - Highlights: • We evaluate building energy codes and standards for climate mitigation. • We use an integrated assessment model and fractional factorial methods. • Decision criteria are energy use, CO2 emitted, and building service cost. • We demonstrate sensitivity analysis for three states. • We identify key variables to propagate with Monte Carlo or surrogate models

  4. Options for promoting high-biodiversity REDD+

    2011-11-15

    International climate and biodiversity conventions agree that to be effective in the long term, strategies to reduce emissions from deforestation, forest degradation, conservation and enhancement of forest carbon stocks, and sustainable forest management (REDD+), must not undermine biodiversity. But how do countries achieve 'high-biodiversity REDD+' in practice? At a global level, options include immediate policy strengthening in international negotiations; promotion of co-benefit standards; and financial incentives and preferences for buying countries. At a national level, developing countries can also promote high-biodiversity REDD+ through more coherent policies; integrated planning; regulatory and economic instruments; and improved monitoring of biodiversity impacts.

    In 2014, California legislators passed the Sustainable Groundwater Management Act (SGMA), which requires groundwater sustainability agencies (areas) to identify/prioritize water basins, develop current and projected water use/needs, develop a groundwater management plan, develop fees, etc. One of the challenges for implementing SGMA is the lack of data that can support alternative groundwater recharge methods such as on-farm flooding. Prior to anthropogenic river control, river floodplains captured excess water during overbank flow in the rainy season in the CA central valley. Today levees and canals strategically route rainy season high flows to the delta/ocean when irrigation water is not needed. Utilizing farmland once again as infiltration basins for groundwater banking and aquifer recharge could be a viable answer to California's depleted central valley aquifers. Prior to 2017, U.C. Davis had partnered with the Almond Board of California (ABC) and local growers to study the efficacy of agricultural flooding and the effects on annual almond crops (. LBNL joined this team to help understand the conveyance of recharge water, using electrical resistivity tomography (ERT), into the subsurface (i.e. localized fast paths, depth of infiltration, etc.) during flooding events. The fate of the recharge water is what is significant to understanding the viability of on-farm flooding as an aquifer recharge option. In this study two orchards (in Delhi and Modesto, CA), each approximately 2 acres, were flooded during the almond tree dormant period (January), to recharge 2 acre/ft of water into the local aquifers. ERT was used to characterize (soil structure) and monitor water infiltration over a single flooding event to investigate the fate of applied water. Data were collected every hour prior to flooding (baseline), during, and after all flood water had infiltrated (about 5 days total). Our time-lapse ERT results show a heterogeneous soil structure that leads to non

    International Nuclear Information System (INIS)

    BOYLES, V.C.

    2001-01-01

    A risk-based priority for the retrieval of Hanford Site waste from the 149 single-shell tanks (SSTs) has been adopted as a result of changes to the Hanford Federal Facility Agreement and Consent Order (HFFACO) (Ecology et al. 1997) negotiated in 2000. Retrieval of the first three tanks in the retrieval sequence fills available capacity in the double-shell tanks (DSTs) by 2007. As a result, the HFFACO change established a milestone (M-45-12-TO1) requiring the determination of options that could increase waste storage capacity for single-shell tank waste retrieval. The information will be considered in future negotiations. This document fulfills the milestone requirement. This study presents options that were reviewed for the purpose of increasing waste storage capacity. Eight options are identified that have the potential for increasing capacity from 5 to 10 million gallons, thus allowing uninterrupted single-shell tank retrieval until the planned Waste Treatment Plant begins processing substantial volumes of waste from the double-shell tanks in 2009. The cost of implementing these options is estimated to range from less than $1 per gallon to more than $14 per gallon. Construction of new double-shell tanks is estimated to cost about $63 per gallon. Providing 5 to 10 million gallons of available double-shell tank space could enable early retrieval of 5 to 9 high-risk single-shell tanks beyond those identified for retrieval by 2007. These tanks are A-101, AX-101, AX-103, BY-102, C-107, S-105, S-106, S-108, and S-109 (Garfield et al. 2000). This represents a potential to retrieve approximately 14 million total curies, including 3,200 curies of long-lived mobile radionuclides. The results of the study reflect qualitative analyses conducted to identify promising options. The estimated costs are rough-order-of magnitude and, therefore, subject to change. Implementing some of the options would represent a departure from the current baseline and may adversely impact the

    It is accepted that coal will continue to play the major role in the supply of energy to the country for the remainder of the century. In this paper, however, emphasis has been directed to those options which could supplement coal in an economic and technically sound manner. The general conclusion is that certain forms of solar energy hold the most promise and it is in this direction that research, development and implementation programmes should be directed. Tidal energy, fusion energy, geothermal energy, hydrogen energy and fuel cells are also discussed as alternative energy options

    2010-12-01

    To what extent do popular social networking channels represent a viable means for disseminating information regarding environmental change to the general public? Are new forms of communication such as YouTube™, Facebook™, MySpace™ and Twitter™ and smart devices such as iPhone™ and BlackBerry™ useful and effective in terms motivating people into social action and behavioural modification; or do they simply pay ‘lip service’ to these pressing environmental issues? This project will explore the background connections between social networking and environmental communication and education; and outline why such tools might be an appropriate way to connect to a broad audience in an efficient and unconventional manner. Further, research will survey the current prevalence of reliable environmental change information on social networking Internet-based media; and finally, suggestions for improved strategies and new directions will be provided.

    Early surrealistic painting and science fiction movies have envisioned dissolvable tattoo electronic devices. In this paper, we will review the recent advances that transform that vision into a viable technology, with extended capabilities even beyond the early vision. Specifically, we focus on the discussion of a stretchable design for tattoo sensors and degradable materials for dissolvable sensors, in the form of inorganic devices with a performance comparable to modern electronics. Integration of these two technologies as well as the future developments of bio-integrated devices is also discussed. Many of the appealing ideas behind developments of these devices are drawn from nature and especially biological systems. Thus, bio-inspiration is believed to continue playing a key role in future devices for bio-integration and beyond.

    1985-01-01

    The authors developed a technique which enables isolation of viable tumour cells subpopulation as a function of their distance from the blood supply. The basis for this separation procedure is that the fluorochrome, Hoechst 33342, as a result of its high avidity for cellular DNA, exhibits a marked diffusion/consumption gradient when it has to pass through several cell layers. As a result intravenous injection of Hoechst 33342 into tumour bearing animals, results in a heterogeneous straining pattern within the tumour with cells close to blood vessels being brightly fluorescent while those more distant are less intensely stained. Since these differences in staining intensity persist after tumour disaggregation, cells can be sorted into subpopulations on the basis of their fluorescence intensity using a fluorescence activated cell sorter. This technique offers the unique possibility of identifying the location of those cell subpopulations resistant to treatment with either radiation or chemotherapeutic drugs

    TiO2 nanoparticle-based dye sensitized solar cells (DSSCs) have attracted a significant level of scientific and technological interest for their potential as economically viable photovoltaic devices. While DSSCs have multiple benefits such as material abundance, a short energy payback period, constant power output, and compatibility with flexible applications, there are still several challenges that hold back large scale commercialization. Critical factors determining the future of DSSCs involve energy conversion efficiency, long-term stability, and production cost. Continuous advancement of their long-term stability suggests that state-of-the-art DSSCs will operate for over 20 years without a significant decrease in performance. Nevertheless, key questions remain in regards to energy conversion efficiency improvements and material cost reduction. In this Perspective, the present state of the field and the ongoing efforts to address the requirements of DSSCs are summarized with views on the future of DSSCs.

    As the culmination of five years of developmental work by Cummins Engines, BC Research Inc., and BC Gas Utility Ltd., a T800 Kenworth truck was outfitted with a new Cummins L10G natural gas engine, and two lightweight fully -wrapped Dynetek cylinders; it was pronounced to be 'a viable clean truck today'. The L10G spark-ignited engine operates at a relatively high peak efficiency of 37 per cent and is commercially available to meet the current California Air Resources Board heavy duty vehicle emission standards without the use of a catalytic converter. The L10G engine produces no particulate emissions, a very significant advantage, in view of the fact that particulate emissions have been identified as major contributors to respiratory ailments

    Inflation in the framework of f(R) modified gravity is revisited. We study the conditions that f(R) should satisfy in order to lead to a viable inflationary model in the original form and in the Einstein frame. Based on these criteria we propose a new logarithmic model as a potential candidate for f(R) theories aiming to describe inflation consistent with observations from Planck satellite (2015). The model predicts scalar spectral index 0.9615

    Application of whole cells in industrial processes requires high catalytic activity, manageability, and viability under technical conditions, which can in principle be accomplished by appropriate immobilization. Here, we report the identification of carrier material allowing exceptionally efficient adsorptive binding of Escherichia coli whole cells hosting catalytically active carbonyl reductase from Candida parapsilosis (CPCR2). With the immobilizates, composite formation with both hydrophobic and hydrophilized silicone was achieved, yielding advanced silCoat-material and HYsilCoat-material, respectively. HYsilCoat-whole cells were viable preparations with a cell loading up to 400 mg(E. coli) · g(-1)(carrier) and considerably lower leaching than native immobilizates. SilCoat-whole cells performed particularly well in neat substrate exhibiting distinctly increased catalytic activity.

  1. Mixed waste management options

    International Nuclear Information System (INIS)

    Owens, C.B.; Kirner, N.P.

    1992-01-01

    Currently, limited storage and treatment capacity exists for commercial mixed waste streams. No commercial mixed waste disposal is available, and it has been estimated that if and when commercial mixed waste disposal becomes available, the costs will be high. If high disposal fees are imposed, generators may be willing to apply extraordinary treatment or regulatory approaches to properly dispose of their mixed waste. This paper explores the feasibility of several waste management scenarios and management options. Existing data on commercially generated mixed waste streams are used to identify the realm of mixed waste known to be generated. Each waste stream is evaluated from both a regulatory and technical perspective in order to convert the waste into a strictly low-level radioactive or a hazardous waste. Alternative regulatory approaches evaluated in this paper include a delisting petition) no migration petition) and a treatability variance. For each waste stream, potentially available treatment options are identified that could lead to these variances. Waste minimization methodology and storage for decay are also considered. Economic feasibility of each option is discussed broadly. Another option for mixed waste management that is being explored is the feasibility of Department of Energy (DOE) accepting commercial mixed waste for treatment, storage, and disposal. A study has been completed that analyzes DOE treatment capacity in comparison with commercial mixed waste streams. (author)

    1983-01-01

    A review of photovoltaic (PV) power technology is presented with an emphasis of PV as an economical and technically feasible alternative source of energy. The successful completion of the development and transfer of emerging low-cost technologies into a fully commercialized status are identified as the means to the realization of this option's full potential. The DOE National Photovoltaics Program, a significant sponsor of PV R&D, expects both flat-plate and concentrator collectors to meet established cost targets. Citing the DOE large flat-plate grid-connected system project of the Sacramento Municipal Utility District, current technology modules priced at near $5/Wp (1983 dollars) are steadily reducing costs. A recent DOE study suggests that PV-generated electricity produced at a 30-year levelized cost of 15 cents per kWh would represent a viable energy supply alternative for the nation.

    In this investigation, five potential manned Mars transportation systems are compared. These options include: (1) a single vehicle, chemically propelled (CHEM) option, (2) a single vehicle, nuclear thermal propulsion (NTP) option, (3) a single vehicle solar electric propulsion (SEP) option, (4) a single vehicle hybrid nuclear electric propulsion (NEP)/CHEM option, and (5) a dual vehicle option (NEP cargo spacecraft and CHEM manned vehicle). In addition to utilizing the initial vehicle weight in low-earth orbit as a measure of mission feasibility, this study addresses the major technological barriers each propulsive scenario must surpass. It is shown that instead of a single clearly superior propulsion system, each means of propulsion may be favored depending upon the specified program policy and the extent of the desired manned flight time. Furthermore, the effect which aerobraking and multiple transfer cycles have upon mission feasibility is considered. 18 refs

    Willetts, J; Fane, S; Mitchell, C

    2007-01-01

    Decentralised systems have the potential to provide a viable option for long term sustainable management of household wastewater. Yet, at present, such systems hold an uncertain status and are frequently omitted from consideration. Their potential can only be realised with improved approaches to their management, and improved methods to decision-making in planning of wastewater systems. The aim of this paper is to demonstrate the value of a novel framework to guide the planning of decentralised systems so that asset management and risk management are explicitly considered. The framework was developed through a detailed synthesis of literature and practice in the area of asset management of centralised water and wastewater systems, and risk management in the context of decentralised systems. Key aspects of the framework are attention to socio-economic risks as well as engineering, public health and ecological risks, the central place of communication with multiple stakeholders and establishing a shared asset information system. A case study is used to demonstrate how the framework can guide a different approach and lead to different, more sustainable outcomes, by explicitly considering the needs and perspectives of homeowners, water authorities, relevant government agencies and society as a whole.

    Berry, Stephen; Davidson, Kathryn

    2015-01-01

    Whilst net zero energy homes are espoused in many policy circles, and many bespoke examples have been constructed to demonstrate their technical feasibility, there is a scarcity of evidence demonstrating such a standard would be economically rational, particularly for large scale housing development where orientation and aspect may not always be optimal. Drawing on energy monitoring evidence and construction economics associated with a nearly zero energy housing estate in Adelaide, Australia, this paper explores the economic feasibility of the net zero energy home policy in warm temperate climates. The results demonstrate that using economic tools and assumptions typically applied for building energy regulatory policy changes, net societal economic benefits significantly outweigh costs. The clear economic outcomes, combined with expected health and productivity benefits from improved levels of thermal comfort, should provide security to policy makers to progress home energy standards towards net zero energy performance. -- Highlights: •The concept of net zero energy homes is examined for economic viability. •Evidence is collected from a near net zero energy housing estate. •Conservative results show that societal benefits outweigh costs. •Significant additional benefits gained from net zero energy homes

    Nelson, K L; Darby, J L

    2001-12-01

    Various reagents commonly used to enumerate viable helminth eggs from wastewater and sludge were evaluated for their potential to inactivate Ascaris eggs under typical laboratory conditions. Two methods were used to enumerate indigenous Ascaris eggs from sludge samples. All steps in the methods were the same except that in method I a phase extraction step with acid-alcohol (35% ethanol in 0.1 N H(2)SO(4)) and diethyl ether was used whereas in method II the extraction step was avoided by pouring the sample through a 38-microm-mesh stainless steel sieve that retained the eggs. The concentration of eggs and their viability were lower in the samples processed by method I than in the samples processed by method II by an average of 48 and 70%, respectively. A second set of experiments was performed using pure solutions of Ascaris suum eggs to elucidate the effect of the individual reagents and relevant combination of reagents on the eggs. The percentages of viable eggs in samples treated with acid-alcohol alone and in combination with diethyl ether or ethyl acetate were 52, 27, and 4%, respectively, whereas in the rest of the samples the viability was about 80%. Neither the acid nor the diethyl ether alone caused any decrease in egg viability. Thus, the observed inactivation was attributed primarily to the 35% ethanol content of the acid-alcohol solution. Inactivation of the eggs was prevented by limiting the direct exposure to the extraction reagents to 30 min and diluting the residual concentration of acid-alcohol in the sample by a factor of 100 before incubation. Also, the viability of the eggs was maintained if the acid-alcohol solution was replaced with an acetoacetic buffer. None of the reagents used for the flotation step of the sample cleaning procedure (ZnSO(4), MgSO(4), and NaCl) or during incubation (0.1 N H(2)SO(4) and 0.5% formalin) inactivated the Ascaris eggs under the conditions studied.

  15. Assessing the impact of policy interventions on the adoption of plug-in electric vehicles: An agent-based model

    International Nuclear Information System (INIS)

    Silvia, Chris; Krause, Rachel M.

    2016-01-01

    Heightened concern regarding climate change and energy independence has increased interest in plug-in electric vehicles as one means to address these challenges and governments at all levels have considered policy interventions to encourage their adoption. This paper develops an agent-based model that simulates the introduction of four policy scenarios aimed at promoting electric vehicle adoption in an urban community and compares them against a baseline. These scenarios include reducing vehicle purchase price via subsidies, expanding the local public charging network, increasing the number and visibility of fully battery electric vehicles (BEVs) on the roadway through government fleet purchases, and a hybrid mix of these three approaches. The results point to the effectiveness of policy options that increased awareness of BEV technology. Specifically, the hybrid policy alternative was the most successful in encouraging BEV adoption. This policy increases the visibility and familiarity of BEV technology in the community and may help counter the idea that BEVs are not a viable alternative to gasoline-powered vehicles. - Highlights: •Various policy interventions to encourage electric vehicle adoption are examined. •An agent based model is used to simulate individual adoption decisions. •Policies that increase the familiarity of electric vehicles are most effective.

    2011-01-01

    Full Text Available Varicocele is one of the most common causes of male infertility. Treatment options for varicoceles includes open varicocelectomy performed at various anatomical levels. Laparoscopic varicocelectomy has been established to be a safe and effective treatment for varicoceles. Robotic surgery has been introduced recently as an alternative surgical option for varicocelectomy. Microsurgical varicocelectomy has gained increasing popularity among experts in male reproductive medicine as the treatment of choice for varicocele because of its superior surgical outcomes. There is a growing volume of literature in the recent years on minimal invasive varicocele treatment with percutaneous retrograde and anterograde venous embolization/sclerotherapy. In this review, we will discuss the advantages and limitations associated with each treatment modality for varicoceles. Employment of these advanced techniques of varicocelectomy can provide a safe and effective approach aiming to eliminate varicocele, preserve testicular function and, in a substantial number of men, increase semen quality and the likelihood of pregnancy.

    Four service and support options are available to healthcare organizations for maintaining their growth arsenals of medical and information technology. These options include maintaining and servicing all equipment using a facility-based biomedical engineering and MIS service department; using a combination of facility-based service and subcontracted service; expanding facility-based biomedical and MIS service departments to provide service to other healthcare organizations to achieve economies of scale; and outsourcing all maintenance, repair, and technical support services. Independent service companies and original equipment manufacturers (OEMs) are offering healthcare organizations a wider array of service and support capabilities than ever before. However, some health systems have successfully developed their own independent service organizations to take care of their own--and other healthcare organizations'--service and support needs.

    2001-01-01

    Future development needs to be sustainable in all of its dimensions if it is to continue to fully contribute to human welfare. In the achievement of this objective, the manner in which energy is produced and consumed is of crucial importance. In the wake of these insights, first attempts begin to provide concrete options for steps towards sustainability in the energy sector. Two criteria can be identified for developing sustainable development policies. First, such policies need to strike a balance between the three dimensions of sustainable development - economic, environmental and social - acknowledging that all three are intrinsically linked. Second, policies in the energy sector need to reduce exposure to large-scale risks and improve the resilience of the energy system through active risk management and diversification. (authors)
