    China issued its first Fuel Economy Standards (FES) for light-duty passenger vehicles (LDPV) in September 2004, and the first and second phases of the FES took effective in July 2005 and January 2008, respectively. The stringency of the Chinese FES ranks third globally, following the Japanese and European standards. In this paper, we first review the policy-making background, including the motivations, key players, and the process; and then explain the content and the features of the FES and why there was no compliance flexibility built into it. Next, we assess the various aspects of the standard's impact, including fuel economy improvement, technology changes, shift of market composition, and overall fuel savings. Lastly, we comment on the prospect of tightening the existing FES and summarize the complementary policies that have been adopted or may be considered by the Chinese government for further promoting efficient vehicles and reducing transport energy consumption. The Chinese experience is highly relevant for countries that are also experiencing or anticipating rapid growth in personal vehicles, those wishing to moderate an increase in oil demand, or those desirous of vehicle technology upgrades.

    2016-06-01

    Full Text Available The emergence of biotechnology is one of the most important changes in the health innovation systems. This paper discusses the rationale that has supported the public policies oriented to boost health biotechnology development in Brazil during 2004 and 2014. Based on a thorough revision of policy documents and on an extensive fieldwork, the study highlights the accumulative path followed by the Brazilian public policies. This research shows how these policies followed an uneven accumulative path were several rationales cohabited integrating explicit and implicit policies. Finally, the boundaries of policy action are discussed, stressing two critical dimensions that delimit the scope of policy action: i the change of policy orientation and rationale, ii that pose new governance’s challenges, which, in turn require new coordination with other implicit policies.

    Full Text Available The growing flows of foreign immigrants toward Spain, as well as their characteristics and the diffusion of the phenomenon through the media, have helped to make immigration a matter of great consequence in spanish society. For this reason, the Government and Public Administrations have undertaken the task of elaborating different proposals for action. These have altered with the changes in the migrant phenomenon and in the dominant political direction. Put together these form the so called «Immigration Policy». The article reviews the main actions of the Spanish Government from the year 1985 until the present time, establishing the differences between a policy of control of flows and an integration policy. The first has been profusely developed, but not the second. The actions put into practice, do not have clear definitions of the main aim (integration or lack sufficient knowledge of the effects of the specific actions. In face of the challenge of designing a coherent integration policy, the article stresses the need to think previously about the way in which this process should be carried out and to count on a solid and reliable methodological tool to help us in this assignment.

  15. Directionality across Diversity: Governing Contending Policy Rationales in the Transition towards the Bioeconomy

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Although the bioeconomy has been embraced by many governments around the world as a way of responding to the grand challenge of climate change, it remains unclear what the bioeconomy is and how it can contribute to achieving these broad policy objectives. The aim of this paper is to improve our understanding of whether, and how, the bioeconomy includes contending rationales for governance and policy-making. In order to do this, we apply a typology of three bioeconomy visions onto the policy discourse on the bioeconomy. These visions are (1 a bio-technology vision; (2 a bio-resource vision; and (3 a bio-ecology vision. Based on a discourse analysis of 41 submissions to a public hearing on the development of a bioeconomy strategy in Norway, the paper explores the actors involved in shaping the new bioeconomy and analyses their positions on this emerging field. The paper finds that it is possible to categorise the consultative inputs into these three visions, and also that the bio-resource vision is predominant, which reflects the structure of the national economy. Moreover, the paper reflects upon how the contending visions observed imply negotiations and power struggles, which may hamper directionality in the current socio-technical transition.

    Full Text Available Recently different studies of green transport have become interesting for policy makers,car manufacturers, customers and energy suppliers. Many stakeholders from the publicand private sectors are investing a lot of effort to identify consumer behaviour for futureimprovements in development of green products and effective strategies, which couldaccelerate the transition to sustainable future. This paper presents the effects of electricvehicle promotional policies and customer preferences about alternative fuel vehicles.This study has shown that the electric vehicle promotional policies adopted in Sloveniahave been unsuccessful, as the share of first-time registered electric vehicles in 2013 wasbelow 1%. For different segments of people whose opinions about low emission vehiclesdiffer, different measures must be adopted. When designing promotional policies focusmust be on the most relevant factors such as the total vehicle price and fuel economy.

    A workshop held on May 18, 2016, at the University of Maryland focused on key principles that should govern state policy decisions intended to ensure the safe operation of autonomous vehicles (AVs). The patchwork approach taken by early state adopters had primarily addressed only testing of these vehicles. As uncertainties in technology and business models play out, and in the absence of more suitable policies and regulations, states are relying on laws created for conventional vehicles to govern AV operations. The workshop addressed these challenges with three panel discussions that examined the underpinnings of policy development, factors affecting policy decisions, and the ultimate impact of AVs in a number of areas, including economic competitiveness; quality of mobility, particularly for disabled community; and energy use and emissions.

    The transportation sector accounts for approximately one-fifth of global final energy consumption and will account for nearly all future growth in oil use, particularly for road vehicles. The right policy mix can allow countries to improve the fuel economy of road vehicles, which in turn can enhance energy security and reduce CO2 emissions. Improving the Fuel Economy of Road Vehicles highlights lessons learned and examples of good practices from countries with experience in implementing fuel economy policies for vehicles. The report, part of the IEA’s Policy Pathway series, outlines key steps in planning, implementation, monitoring and evaluation. It complements the IEA Technology Roadmap: Fuel Economy for Road Vehicles, which outlines technical options, potentials, and costs towards improvement in the near, medium and long term.

    The U.S. federal government first introduced incentives for plug-in electric vehicles (PEVs) through the American Clean Energy and Security Act of 2009, which provided a tax credit of up to $7,500 for a new PEV purchase. Soon after, in December 2010, two mass-market PEVs were introduced, the plug-in hybrid electric vehicle (PHEV) Chevrolet Volt and the battery electric vehicle (BEV) Nissan LEAF. Since that time, numerous additional types of PEV incentives have been provided by federal and regional (state or city) government agencies and utility companies. These incentives cover vehicle purchases as well as the purchase and installation of electric vehicle supply equipment (EVSE) through purchase rebates, tax credits, or discounted purchase taxes or registration fees. Additional incentives, such as free high-occupancy vehicle (HOV) lane access and parking benefits, may also be offered to PEV owners. Details about these incentives, such as the extent to which each type is offered by region, can be obtained from the U.S. Department of Energy (DOE) Alternative Fuel Data Center (http://www.afdc.energy.gov/). In addition to these incentives, other policies, such as zero-emission vehicle (ZEV) mandates,1 have also been implemented, and community-scale federal incentives, such as the DOE PEV Readiness Grants, have been awarded throughout the country to improve PEV market penetration. This report reviews 18 studies that analyze the impacts of past or current incentives and policies that were designed to support PEV adoption in the U.S. These studies were selected for review after a comprehensive survey of the literature and discussion with a number of experts in the field. The report summarizes the lessons learned and best practices from the experiences of these incentive programs to date, as well as the challenges they face and barriers that inhibit further market adoption of PEVs.

    2003-01-01

    Full Text Available Various control policies, such as skyhook and groundhook control, have often been considered for semi-active vehicle suspensions. Past studies have shown the performance limitations of these policies, as well as others that have been considered for vehicle applications. This study will provide a look into an alternative control technique called "hybrid control", which attempts to merge the performance benefits of skyhook and groundhook control. The results of this study are based on an experimental evaluation of hybrid control using a quarter-car rig and a magneto-rheological damper. The control policy is employed and evaluated under a steady-state or pure tone input, and a transient or step input. Peak-to-peak displacement and peak-to-peak acceleration are used to evaluate performance. The results indicate that hybrid control can offer benefits to both the sprung mass and the unsprung mass. The steady-state results reveal that hybrid control can be used to reduce the peak-to- peak displacements and accelerations of both bodies. The transient evaluation shows that hybrid control can be effective at reducing the peak-to-peak displacement of the sprung mass.

    Full Text Available Comprehensive insurance is the coverage purchased by the individuals in exchange for the premiums paid for insuring their movable properties against the damages caused by either their or others’ faults. Comprehensive insurance is generally rooted in the automotive sector and its applications are generally designed for this sector. Vehicle owners buy their vehicles according to their tastes using a considerable part of their savings. Purchasing of a comprehensive car insurance policy means that the purchaser is transferring the costs borne by the risks to be occurred related to his or her vehicle to the insurance company. Thus, the vehicle is insured against any costs arise in case of any damage. This study were examined to investigate the comprehensive car insurance policy ownership ratio of vehicle owners, factors that may be affecting the ownership of such policies, opinions of policy owners on the insurance company providing the coverage and the factors affecting the decision of not purchasing comprehensive car insurance policies.

  7. Ethnocentrism is an unacceptable rationale for health care policy: a critique of transplant tourism position statements.

    Science.gov (United States)

    Evans, R W

    2008-06-01

    Medical tourism has emerged as a global health care phenomenon, valued at $60 billion worldwide in 2006. Transplant tourism, unlike other more benign forms of medical tourism, has become a flashpoint within the transplant community, underscoring the uneasy relationships among science, religion, politics, ethics and international health care policies concerning the commercialization of transplantation. Numerous professional associations have drafted or issued position statements condemning transplant tourism. Often the criticism is misdirected. The real issue concerns both the source and circumstances surrounding the procurement of donor organs, including commercialization. Unfortunately, many of the position statements circulated to date represent an ethnocentric and decidedly western view of transplantation. As such, the merits of culturally insensitive policy statements issued by otherwise well-intended transplant professionals, and the organizations they represent, must be evaluated within the broader context of foreign relations and diplomacy, as well as cultural and ethical relativity. Having done so, many persons may find themselves reluctant to endorse statements that have produced a misleading social desirability bias, which, to a great extent, has impeded more thoughtful and inclusive deliberations on the issues. Therefore, instead of taking an official position on policy matters concerning the commercial aspects of transplantation, international professional associations should offer culturally respectful guidance.

    2005-01-01

    To examine differences in motor vehicle crash involvement for teenagers in communities with and without school policies enabling teens to drive off campus during lunchtime. Comparison of lunchtime motor vehicle crashes involving teen drivers in two North Carolina counties having open-lunch policies with a third county without an open-lunch policy. We also compare crash rates during the before-school period and at all times of the day in the three counties. Data were analyzed by computing rate ratios of teens' involvement in a crash during the three time periods and comparing them among the three counties. Crash rates over the lunch hours were significantly higher for teenagers in the counties with open-lunch policies, despite these counties having no elevated crash risk during other time periods. This resulted in a relative risk of lunchtime crash involvement of 3.10 and 2.98 (95% CI 1.97-4.89 and 1.87-4.74, respectively) compared with the county without an open-lunch policy. Number of vehicle occupants also increased during the lunch hours in the counties with open-lunch policies. Open-lunch policies contribute to motor vehicle crashes in teenagers and encourage a situation where there are multiple occupants per vehicle, a known risk factor for teenage motor vehicle crashes.

  10. Ethical and policy issues in cluster randomized trials: rationale and design of a mixed methods research study

    Directory of Open Access Journals (Sweden)

    Chaudhry Shazia H

    2009-07-01

    Full Text Available Abstract Background Cluster randomized trials are an increasingly important methodological tool in health research. In cluster randomized trials, intact social units or groups of individuals, such as medical practices, schools, or entire communities – rather than individual themselves – are randomly allocated to intervention or control conditions, while outcomes are then observed on individual cluster members. The substantial methodological differences between cluster randomized trials and conventional randomized trials pose serious challenges to the current conceptual framework for research ethics. The ethical implications of randomizing groups rather than individuals are not addressed in current research ethics guidelines, nor have they even been thoroughly explored. The main objectives of this research are to: (1 identify ethical issues arising in cluster trials and learn how they are currently being addressed; (2 understand how ethics reviews of cluster trials are carried out in different countries (Canada, the USA and the UK; (3 elicit the views and experiences of trial participants and cluster representatives; (4 develop well-grounded guidelines for the ethical conduct and review of cluster trials by conducting an extensive ethical analysis and organizing a consensus process; (5 disseminate the guidelines to researchers, research ethics boards (REBs, journal editors, and research funders. Methods We will use a mixed-methods (qualitative and quantitative approach incorporating both empirical and conceptual work. Empirical work will include a systematic review of a random sample of published trials, a survey and in-depth interviews with trialists, a survey of REBs, and in-depth interviews and focus group discussions with trial participants and gatekeepers. The empirical work will inform the concurrent ethical analysis which will lead to a guidance document laying out principles, policy options, and rationale for proposed guidelines. An

  11. Public policies for hybrid-electric vehicles: The impact of government incentives on consumer adoption

    Science.gov (United States)

    Diamond, David B.

    This dissertation examines the outcomes and effectiveness of public policies designed to promote the adoption of hybrid-electric vehicles (HEVs). As a primary methodology, I employ cross-sectional analysis of hybrid registration data over time for U.S. states and Virginia municipalities to examine the relationship between hybrid adoption and a variety of socioeconomic and policy variables. I also compare hybrid adoption patterns over time to the U.S. average for specific states that have changed incentive policies, to determine whether these policy changes are consistent with significant changes in adoption patterns. The results of these analyses suggest a strong relationship between gasoline prices and hybrid adoption, but a much weaker relationship between incentive policies and hybrid adoption. Incentives that allow hybrids to access High Occupancy Vehicle (HOV) lanes with only one occupant may also be effective in promoting adoption, but only under specific circumstances and with the potential for significant unintended consequences.

    2012-01-01

    In the recent years, China's auto industry develops rapidly, thus bringing a series of burdens to society and environment. This paper uses Logistic model to simulate the future trend of China's vehicle population and finds that China's auto industry would come into high speed development time during 2020-2050. Moreover, this paper predicts vehicles' fuel consumption and exhaust emissions (CO, HC, NO(x), and PM) and quantificationally evaluates related industry policies. It can be concluded that (1) by 2020, China should develop at least 47 million medium/heavy hybrid cars to prevent the growth of vehicle fuel consumption; (2) China should take the more stringent vehicle emission standard V over 2017-2021 to hold back the growth of exhaust emissions; (3) developing new energy vehicles is the most effective measure to ease the pressure brought by auto industry.

  13. Consumer-Oriented Policy towards Diffusion of Electric Vehicles: City-Level Evidence from China

    Directory of Open Access Journals (Sweden)

    Guoqiang Zhang

    2016-12-01

    Full Text Available Public policy is crucial for the diffusion of green innovation, and debates exist about the effects of different policies. This paper explores appropriate types of policy instruments by explaining the quick rise in sales of electric vehicles (EVs in China. Based on a three-year longitudinal dataset across 88 cities, the study shows that consumer-oriented policies are able to significantly promote EV diffusion. Consumer-oriented policies target consumers to facilitate their usage of cars and lower the lifecycle cost, and typical examples include electricity charging and traffic management. This paper contributes to the literature of clean technology policy in two ways. Firstly, it reveals and empirically tests the importance of consumer-oriented policy instruments for the deployment of green innovation. Secondly, it is one of very few scholarly works offering a detailed review of city-level policies in China’s EV industry, which will be useful for scholars who are also interested in similar topics.

  14. SDP Policy Iteration-Based Energy Management Strategy Using Traffic Information for Commuter Hybrid Electric Vehicles

    Directory of Open Access Journals (Sweden)

    Xiaohong Jiao

    2014-07-01

    Full Text Available This paper demonstrates an energy management method using traffic information for commuter hybrid electric vehicles. A control strategy based on stochastic dynamic programming (SDP is developed, which minimizes on average the equivalent fuel consumption, while satisfying the battery charge-sustaining constraints and the overall vehicle power demand for drivability. First, according to the sample information of the traffic speed profiles, the regular route is divided into several segments and the statistic characteristics in the different segments are constructed from gathered data on the averaged vehicle speeds. And then, the energy management problem is formulated as a stochastic nonlinear and constrained optimal control problem and a modified policy iteration algorithm is utilized to generate a time-invariant state-dependent power split strategy. Finally, simulation results over some driving cycles are presented to demonstrate the effectiveness of the proposed energy management strategy.

  15. Rationale and Consequences of Reclassifying Obesity as an Addictive Disorder: Neurobiology, Food Environment and Social Policy Perspectives

    Allen, Patricia; Batra, Payal; Geiger, Brenda M.; Wommack, Tara; Gilhooly, Cheryl; Pothos, Emmanuel N.

    2012-01-01

    The rapid increase in the prevalence of obesity is a priority for investigators from across numerous disciplines, including biology, nutritional science, and public health and policy. In this paper, we systematically examine the premise that common dietary obesity is an addictive disorder, based on the criteria for addiction described in the Diagnostic and Statistical Manual (DSM) of Mental Disorders of the American Psychiatric Association, version IV, and consider the consequences of such a reclassification of obesity for public policy. Specifically, we discuss evidence from both human and animal studies investigating the effects of various types and amounts of food and the food environment in obese individuals. Neurobiological studies have shown that the hedonic brain pathways activated by palatable food overlap considerably with those activated by drugs of abuse and suffer significant deficits after chronic exposure to high-energy diets. Furthermore, food as a stimulus can induce the sensitization, compulsion and relapse patterns observed in individuals who are addicted to illicit drugs. The current food environment encourages these addictive-like behaviors where increased exposure through advertisements, proximity and increased portion sizes are routine. Taking lessons from the tobacco experience, it is clear that reclassifying common dietary obesity as an addictive disorder would necessitate policy changes (e.g., regulatory efforts, economic strategies, and educational approaches). These policies could be instrumental in addressing the obesity epidemic, by encouraging the food industry and the political leadership to collaborate with the scientific and medical community in establishing new and more effective therapeutic approaches.

    The rapid increase in the prevalence of obesity is a priority for investigators from across numerous disciplines, including biology, nutritional science, and public health and policy. In this paper, we systematically examine the premise that common dietary obesity is an addictive disorder, based on the criteria for addiction described in the Diagnostic and Statistical Manual (DSM) of Mental Disorders of the American Psychiatric Association, version IV, and consider the consequences of such a reclassification of obesity for public policy. Specifically, we discuss evidence from both human and animal studies investigating the effects of various types and amounts of food and the food environment in obese individuals. Neurobiological studies have shown that the hedonic brain pathways activated by palatable food overlap considerably with those activated by drugs of abuse and suffer significant deficits after chronic exposure to high-energy diets. Furthermore, food as a stimulus can induce the sensitization, compulsion and relapse patterns observed in individuals who are addicted to illicit drugs. The current food environment encourages these addictive-like behaviors where increased exposure through advertisements, proximity and increased portion sizes are routine. Taking lessons from the tobacco experience, it is clear that reclassifying common dietary obesity as an addictive disorder would necessitate policy changes (e.g., regulatory efforts, economic strategies, and educational approaches). These policies could be instrumental in addressing the obesity epidemic, by encouraging the food industry and the political leadership to collaborate with the scientific and medical community in establishing new and more effective therapeutic approaches.

  17. Market barriers to energy efficiency: A critical reappraisal of the rationale for public policies to promote energy efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Golove, W.H.; Eto, J.H. [Lawrence Berkeley National Lab., CA (United States). Energy and Environment Div.

    1996-03-01

    This report reviews current perspectives on market barriers to energy efficiency. Ratepayer-funded utility energy-efficiency programs are likely to change in scope, size, and nature as the deregulation process proceeds; the authors research focuses on understanding to what extent some form of future intervention may be warranted and how they might judge the success of particular interventions, especially those funded by ratepayers. They find that challenges to the existence of market barriers have, for the most part, failed to provide a testable alternative explanation for evidence suggesting that there is a substantial ``efficiency gap`` between a consumer`s actual investments in energy efficiency and those that appear to be in the consumer`s own interest. They then suggest that differences of opinion about the appropriateness of public policies stem not from disputes about whether market barriers exist, but from different perceptions of the magnitude of the barriers, and the efficacy and (possibly unintended) consequences of policies designed to overcome them. They conclude that there are compelling justifications for future energy-efficiency policies. Nevertheless, in order to succeed, they must be based on a sound understanding of the market problems they seek to correct and a realistic assessment of their likely efficacy. This understanding can only emerge from detailed investigations of the current operation of individual markets.

  18. Comparative Studies on Vehicle Related Policies for Air Pollution Reduction in Ten Asian Countries

    2010-01-01

    Full Text Available Asian countries are facing major air pollution problems due to rapid economic growth, urbanization and motorization. Mortality and respiratory diseases caused by air pollution are believed to be endemic in major cities of these countries. Regulations and standards are the first requirement for reducing emissions from both fixed and mobile sources. This paper emphasizes monitoring problems such as vehicle registration systems, inspection and maintenance (I/M systems and fuel quality monitoring systems for vehicles in use. Monitoring problems in developing countries share similar characteristics such as a weakness in government initiatives and inadequate operation of government agencies, which results from a lack of human resources and availability of adequate facilities. Finally, this paper proposes a method to assure air quality improvements under the different shares of emission regulations in these Asian countries and introduces an example of an evaluation method based on a policy survey to improve air quality.

    Vehicle emissions are a major source of urban air pollution. In recent decade, the Chinese government has introduced a range of policies to reduce vehicle emissions. In order to understand the chemical characteristics of PM2.5 from on-road vehicle emissions in the Pearl River Delta (PRD) region and to evaluate the effectiveness of control policies on vehicle emissions, the emission factors of PM2.5 mass, elemental carbon (EC), organic carbon (OC), water-soluble organic carbon (WSOC), water-soluble inorganic ions (WSII), metal elements, organic compounds and stable carbon isotopic composition were measured in the Zhujiang tunnel of Guangzhou, in the PRD region of China in 2013. Emission factors of PM2.5 mass, OC, EC and WSOC were 92.4, 16.7, 16.4 and 1.31 mg vehicle-1 km-1 respectively. Emission factors of WSII were 0.016 (F-) ~ 4.17 (Cl-) mg vehicle-1 km-1, contributing about 9.8% to the PM2.5 emissions. The sum of 27 measured metal elements accounted for 15.2% of PM2.5 emissions. Fe was the most abundant metal element, with an emission factor of 3.91 mg vehicle-1 km-1. Emission factors of organic compounds including n-alkanes, polycyclic aromatic hydrocarbons, hopanes and steranes were 91.9, 5.02, 32.0 and 7.59 μg vehicle-1 km-1, respectively. Stable carbon isotopic composition δ13C value was -25.0‰ on average. An isotopic fractionation of 3.2‰ was found during fuel combustion. Compared to a previous study in Zhujiang tunnel in 2004, emission factors of PM2.5mass, EC, OC, WSII except Cl- and organic compounds decreased by 16.0 ~ 93.4%, which could be attributed to emission control policy from 2004 to 2013. However, emission factors of most of the metal elements increased significantly, which could be partially attributed to the changes in motor oil additives and vehicle conditions. There are no mandatory national standards to limit metal content from vehicle emissions, which should be a concern of the government. A snapshot of the 2013 characteristic

    Full Text Available Sovereign funds are an important actor occurring on international financial markets in the last decade, being, in fact, state controlled international investments. Generally, they are financed from foreign currency reserves of the emergent countries they are constituted in, being managed apart of the official reserves and used for external expansion; they are likely to be detrimental to certain strategic interests. As public financial vehicles, they own, endorse or manage public funds of some emergent countries, freely invested by them in a great number of assets, being seen as a foreign policy element.

    2017-06-01

    The high volume of freight vehicles that enters, leaves or passes through the urban areas, especially Jakarta, has caused traffic congestion. Local authority plans to perform the access restriction on freight vehicles on the Jakarta Outer Ring Road (JORR) to reduce the congestion on that toll road. The study aims to analyze the alternative solutions of the logistics companies to overcome the impact of such policy. The data collection is done by interviewing 102 truck drivers and 7 staffs of logistic companies that use JORR. The results show that the most preferred action is shifting the operating time. Based on the open test, access restriction policy on JORR may cause a significant impact on the operational costs of delivery. Shifting the operational time will increase the operating cost by 1.71%, while turning the route will increase the operating costs by 4.35%. Moreover, changing the mode will reduce the operating expenses by 50%, and the combination action of shifting the route and the time will increase the operating costs by 5.39%.

    Debinski, Beata; Clegg Smith, Katherine; Gielen, Andrea

    2014-01-01

    Legislation is an effective strategy for reducing road-related fatalities and injuries. Public opinion can be an impetus for passing new laws and can affect the success of their implementation, but little is known about the current state of public opinion toward existing and proposed road-related policies in the United States. This review describes the scope and results of research on public support for state- and local-level evidence-based motor vehicle- and bicycle-related policies. We identify gaps in our understanding of public support for these policies. Published U.S. literature and all reports from the NHTSA from the past decade (2003-2012) were searched for data on opinions about existing or proposed policies related to motor vehicle or bicycle injury prevention. Twenty-six studies fulfilled the inclusion criteria. In all, studies reported public opinion about 7 injury prevention topic areas: all-terrain vehicles (n = 1), automated enforcement with red light and speed cameras (n = 5), distracted driving (n = 4), drinking and driving (n = 5), graduated driver licensing (n = 7), helmets (n = 7), and seat belts (n = 4). Twenty-three studies focused only on one topic, and 3 sought public opinion about multiple topic areas. The studies revealed generally high levels of support for injury prevention policies in all topic areas. Fifteen studies collected information from national samples, and only 7 studies reported data from the state (n = 5) or local (n = 2) level. There is a relatively small evidence base on public opinion related to motor vehicle- and bicycle-related evidence-based policies; even less is less known for state- or county-specific policies. The findings of this review suggest that the public's opinion toward injury prevention legislation is generally favorable. This information can be used to communicate with the media and policy makers to reinforce the need for effective policy solutions to continuing motor vehicle injury problems. More research

  9. Assessment for Fuel Consumption and Exhaust Emissions of China’s Vehicles: Future Trends and Policy Implications

    2012-01-01

    Full Text Available In the recent years, China’s auto industry develops rapidly, thus bringing a series of burdens to society and environment. This paper uses Logistic model to simulate the future trend of China’s vehicle population and finds that China’s auto industry would come into high speed development time during 2020–2050. Moreover, this paper predicts vehicles’ fuel consumption and exhaust emissions (CO, HC, NOx, and PM and quantificationally evaluates related industry policies. It can be concluded that (1 by 2020, China should develop at least 47 million medium/heavy hybrid cars to prevent the growth of vehicle fuel consumption; (2 China should take the more stringent vehicle emission standard V over 2017–2021 to hold back the growth of exhaust emissions; (3 developing new energy vehicles is the most effective measure to ease the pressure brought by auto industry.

    In Norway the sale of electric vehicles per capita is higher than in any other country. The high share of electric vehicles has been achieved by a broad range of government incentives which have been introduced to help Norway reduce GHG emissions. The electric vehicle is more environmentally friendly, but produces approximately the same amount of road use externalities as the conventional vehicle. According to literature on optimal environmental taxation the electric vehicle should therefore ...

  11. Evaluating the effect of vehicle impoundment policy on illegal construction and demolition waste dumping: Israel as a case study.

    Construction and demolition (C&D) waste dumped alongside roads and in open areas is a major source of soil and underground water pollution. Since 2006, Israeli ministry for environmental protection enacted a policy of vehicle impoundment (VI) according to which track drivers caught while dumping C&D waste illegally have their vehicles impounded. The present study attempted to determine whether the VI policy was effective in increasing the waste hauling to authorized landfill sites, thus limiting the number of illegal unloads of C&D waste at unauthorized landfill sites and in open areas. During the study, changes in the ratio between the monthly amount of C&D waste brought to authorized landfills sites and the estimated total amount of C&D waste generated in different administrative districts of Israel were examined, before and after the enactment of the 2006 VI policy. Short questionnaires were also distributed among local track drivers in order to determine the degree of awareness about the policy in question and estimate its deterrence effects. According to the study's results, in the district of Haifa, in which the VI policy was stringently enacted, the ratio between C&D waste, dumped in authorized landfill sites, and the total amount of generated C&D waste, increased, on the average, from 20% in January 2004 to 35% in October 2009, with the effect attributed to the number of vehicle impoundments being highly statistically significant (t=2.324; p0.1). The analysis of the questionnaires, distributed among the local truck drivers further indicated that the changes observed in the district of Haifa are not coincident and appeared to be linked to the VI policy's enactment. In particular, 62% of the truck drivers, participated in the survey, were aware of the policy and 47% of them personally knew a driver whose vehicle was impounded. Furthermore, the drivers estimated the relative risk of being caught for unloading C&D waste in unauthorized sites, on the average, as

    Concerns about climate change, urban air pollution and dependence on unstable and expensive supplies of foreign oil have led policy-makers and researchers to investigate alternatives to conventional petroleum-fuelled internal-combustion-engine vehicles in transportation. Because vehicles that get some or all of their power from an electric drivetrain can have low or even zero emissions of greenhouse gases (GHGs) and urban air pollutants, and can consume little or no petroleum, there is considerable interest in developing and evaluating advanced electric vehicles (EVs), including pure battery-electric vehicles, plug-in hybrid electric vehicles and hydrogen fuel-cell electric vehicles. To help researchers and policy-makers assess the potential of EVs to mitigate climate change and reduce petroleum use, this paper discusses the technology of EVs, the infrastructure needed for their development, impacts on emissions of GHGs, petroleum use, materials use, lifetime costs, consumer acceptance and policy considerations.

    In most western cities the present-day car is by far the principal mode of transport. The wrong side of it is that automobile circulation is a source of air-pollution, noise and traffic jam, inconveniences against which public opinion shows itself more and more susceptible. Facing this situation governments in succession have since several years encouraged by different measures the development of fitted or alternative vehicles: electric, natural gas (NG) fuelled and liquefied petroleum gas (LPG) vehicles. These vehicles have the advantage of responding both to pollution problem and energy diversification challenge. The present-day regulation system gathers a number of attractive provisions: - maintaining para-fiscal taxes upon gas fuels at a level much lower than for other fuels; - VAT refunding for these gas fuels and electricity consumed by vehicles of this type; - general councils can be totally or partially exonerated from automobile taxation; - assigning future green label allowing these vehicles to be excepted from traffic restrictions applied to cope with pollution peaks. Other additional advantages are provided by the law on air and rational use of energy of 30 December 1996. Merits and drawbacks of each of the mentioned types of alternative vehicles are reviewed. So, although entirely un-polluting the electric cars are not cheap and what is even more hindering is their very limited range which for current batteries does not exceed 80 km. Only little over 3000 electric vehicles were sold, a third of them to EDF. The natural gas is rather pure a fuel at burning of which the release of sulfur and solid particles are practically negligible. Due to its characteristics, the short and medium term development of this alternative seems to reside only in buses and service vehicles, the only able to support the supplementary load of high pressure gas tanks. Being formed of liquefied butane and propane at low pressure, LPG is as attractive as NG, with respect to the

    This study examines the associations between alcohol policies and motor vehicle fatality rates from 1984 to 1995 in the United States. State policies and state characteristics variables were merged with motor vehicle fatality rates over an 11 year period and analyzed using minimum logit chi-square method and fixed effects to create a quasi time-series analysis. Laws allowing individuals to sue bars for the drunken behavior of their patrons were the policies most strongly associated with lower minor and adult fatality rates. The mandatory first offense fine was associated with lower minor fatality rates but not adult fatality rates, while minor and adult rates fell after administrative per se license suspension and anti-consumption laws for all vehicle occupants. Many other public policies evaluated were not associated with lower fatality rates.

    Since natural and triggered lightning are demonstrated hazards to launch vehicles, payloads, and spacecraft, NASA and the Department of Defense (DoD) follow the Lightning Launch Commit Criteria (LLCC) for launches from Federal Ranges. The LLCC were developed to prevent future instances of a rocket intercepting natural lightning or triggering a lightning flash during launch from a Federal Range. NASA and DoD utilize the Lightning Advisory Panel (LAP) to establish and develop robust rationale from which the criteria originate. The rationale document also contains appendices that provide additional scientific background, including detailed descriptions of the theory and observations behind the rationales. The LLCC in whole or part are used across the globe due to the rigor of the documented criteria and associated rationale. The Federal Aviation Administration (FAA) adopted the LLCC in 2006 for commercial space transportation and the criteria were codified in the FAA's Code of Federal Regulations (CFR) for Safety of an Expendable Launch Vehicle (Appendix G to 14 CFR Part 417, (G417)) and renamed Lightning Flight Commit Criteria in G417.

    Plug-in hybrid electric vehicles (PHEVs) can use both grid-supplied electricity and liquid fuels. We show that under recent conditions, millions of PHEVs could have charged economically in California during both peak and off-peak hours even with modest gasoline prices and real-time electricity pricing. Special electricity rate tariffs already in place for electric vehicles could successfully render on-peak charging uneconomical and off-peak charging very attractive. However, unless battery prices fall by at least a factor of two, or gasoline prices double, the present value of fuel savings is smaller than the marginal vehicle costs, likely slowing PHEV market penetration in California. We also find that assumptions about how PHEVs are charged strongly influence the number of PHEVs that can be charged before the electric power system must be expanded. If most PHEVs are charged after the workday, and thus after the time of peak electricity demand, our forecasts suggest that several million PHEVs could be deployed in California without requiring new generation capacity, and we also find that the state's PHEV fleet is unlikely to reach into the millions within the current electricity sector planning cycle. To ensure desirable outcomes, appropriate technologies and incentives for PHEV charging will be needed if PHEV adoption becomes mainstream.

    2008-05-01

    Plug-in hybrid electric vehicles (PHEVs), which use electricity from the grid to power a portion of travel, could play a role in reducing greenhouse gas (GHG) emissions from the transport sector. However, meaningful GHG emissions reductions with PHEVs are conditional on low-carbon electricity sources. We assess life cycle GHG emissions from PHEVs and find that they reduce GHG emissions by 32% compared to conventional vehicles, but have small reductions compared to traditional hybrids. Batteries are an important component of PHEVs, and GHGs associated with lithium-ion battery materials and production account for 2-5% of life cycle emissions from PHEVs. We consider cellulosic ethanol use and various carbon intensities of electricity. The reduced liquid fuel requirements of PHEVs could leverage limited cellulosic ethanol resources. Electricity generation infrastructure is long-lived, and technology decisions within the next decade about electricity supplies in the power sector will affectthe potential for large GHG emissions reductions with PHEVs for several decades.

    Policy options to reduce passenger transport emissions in Europe are simulated with the EUCARS model. The EUCARS welfare analysis includes changes in consumer surplus, congestion and tax revenues. Simulations also address consumer myopia, i.e., the underestimation of fuel costs by car buyers. The best policy mix to reduce CO{sub 2} consists of fuel taxes that are combined with differentiated purchase taxes to correct for the assumed myopia. This combination could reduce CO{sub 2} emissions of over 25% without reducing contemporaneous well-being. For the reduction of conventional emissions, an equivalent best mix includes an emissions-based kilometre tax combined with a purchase feebate. This mix allows a 60% reduction in toxic emissions without any noticeable welfare reduction. The overall superiority of these two mixes compared to alternative choices is higher when the evaluation includes a broad group of externalities, a premium on public funds, and positive feedbacks across emissions categories. Local traffic management measures are important zero-cost complements for an overall emissions strategy.

  7. A rationale for intra-party democracy

    OpenAIRE

    Zudenkova, Galina

    2012-01-01

    This paper provides a rationale for intra-party democracy within a political agency model with moral hazard. The focus is on the party's internal procedures for policy determination. I show that democratizing those procedures benefits the party leadership, which seeks to maximize joint reelection chances of the party's incumbents. The reason is that under intra-party democracy, the voters adopt less demanding reappointment rules and reelect the party's incumbents more often than under leaders...

  8. Does Design Rationale Enhance Creativity?

    Full Text Available Creativity and rationale are often viewed as two contrasting facets in software design. A lack in recognizing the facilitative relationship between creativity and rationale not only underestimates the benefits designers can obtain from rationale practices, but also confines the approaches that support creativity in software design. Our exploratory study provides empirical evidence of the positive correlation between rationale and creativity. Furthermore, we found that the feasibility of design alternatives and the comprehensiveness of tradeoff evaluation are critical to enhancing novelty, persuasiveness, and insightfulness. We also discuss future directions to further understand how these properties, or rationale quality in general, affects design creativity.

    Steward, Darlene; Sears, Ted

    2017-02-01

    The Energy Policy Act (EPAct) of 1992, with later amendments, was enacted with the goal of reducing U.S. petroleum consumption by building a core market for alternative fuels and vehicles. The U.S. Department of Energy manages three federal programs related to EPAct; the Sustainable Federal Fleets Program, the State and Alternative Fuel Provider Program, and Clean Cities. Federal agencies and State and Alternative Fuel Provider Fleets are required to submit annual reports that document their compliance with the legislation. Clean Cities is a voluntary program aimed at building partnerships and providing technical expertise to encourage cities to reduce petroleum use in transportation. This study reviews the evolution of these three programs in relation to alternative fuel and vehicle markets and private sector adoption of alternative fueled vehicles to assess the impact of the programs on reduction in petroleum use and greenhouse gas emissions both within the regulated fleets and through development of alternative fuel and vehicle markets. The increased availability of alternative fuels and use of alternative fuels in regulated fleets is expected to improve cities' ability to respond to and quickly recover from both local disasters and short- and long-term regional or national fuel supply interruptions. Our analysis examines the benefits as well as potential drawbacks of alternative fuel use for the resiliency of U.S. cities.

    This article is an analytical report on the 20-year trajectory of the 'medical rationale' category that emerged in the early 1990s in the area of Social and Human Sciences in Health in the field of Public Health. Its objective was to study complex and therapeutic medical systems and traditional, complementary and alternative medicines. Based on a critical review of the literature, it presents some aspects of the cultural, political, institutional and social context of its emergence, as well as its main contributions and developments on a theoretical level and on social policies and practices in health. The southern epistemology concept of Boaventura de Sousa Santos is used to reflect upon the contribution of the 'medical rationale' category to the critique of the post-modern scientific rationale and to the creation of a new epistemology in health.

    Energy Technology Data Exchange (ETDEWEB)

    Goddard, H.C. [Instituto Tecnologico Autonomo de Mexico, Mexico City (Mexico)

    1997-07-01

    Many large cities in the world have serious ground level ozone problems, largely the product of vehicular emissions and thus the argued unsustainability of current urban growth patterns is frequently blamed on unrestricted private vehicle use. This article reviews Mexico City`s experience with vehicle use restrictions as an emissions control program and develops the conditions for optimal quantitative restrictions on vehicle use and for complementary abatement technologies. The stochastic nature of air pollution outcomes is modelled explicitly in both the static and dynamic formulations of the control problem, in which for the first time in the literature the use of tradeable vehicle use permits is proposed as a cost-effective complement to technological abatement for mobile emissions control. This control regime gives the authorities a broader and more flexible set of instruments with which to deal more effectively with vehicle emissions, and with seasonal and stochastic variation of air quality outcomes. The market in tradeable vehicle use permits would be very competitive with low transactions costs. This control policy would have very favorable impacts on air quality, vehicle congestion and on urban form and development. Given the general political resistance to environmental taxes, this program could constitute a workable and politically palatable set of policies for controlling greenhouse gas emissions from the transport sector. 7 figs., 1 appendix, 23 refs.

  20. A life-cycle approach to technology, infrastructure, and climate policy decision making: Transitioning to plug-in hybrid electric vehicles and low-carbon electricity

    Science.gov (United States)

    Samaras, Constantine

    In order to mitigate the most severe effects of climate change, large global reductions in the current levels of anthropogenic greenhouse gas (GHG) emissions are required in this century to stabilize atmospheric carbon dioxide (CO2) concentrations at less than double pre-industrial levels. The Intergovernmental Panel on Climate Change (IPCC) fourth assessment report states that GHG emissions should be reduced to 50-80% of 2000 levels by 2050 to increase the likelihood of stabilizing atmospheric CO2 concentrations. In order to achieve the large GHG reductions by 2050 recommended by the IPCC, a fundamental shift and evolution will be required in the energy system. Because the electric power and transportation sectors represent the largest GHG emissions sources in the United States, a unique opportunity for coupling these systems via electrified transportation could achieve synergistic environmental (GHG emissions reductions) and energy security (petroleum displacement) benefits. Plug-in hybrid electric vehicles (PHEVs), which use electricity from the grid to power a portion of travel, could play a major role in reducing greenhouse gas emissions from the transport sector. However, this thesis finds that life cycle GHG emissions from PHEVs depend on the electricity source that is used to charge the battery, so meaningful GHG emissions reductions with PHEVs are conditional on low-carbon electricity sources. Power plants and their associated GHGs are long-lived, and this work argues that decisions made regarding new electricity supplies within the next ten years will affect the potential of PHEVs to play a role in a low-carbon future in the coming decades. This thesis investigates the life cycle engineering, economic, and policy decisions involved in transitioning to PHEVs and low-carbon electricity. The government has a vast array of policy options to promote low-carbon technologies, some of which have proven to be more successful than others. This thesis uses life

    A growing population and urbanization is a challenge for finite natural resources. Without strict regulation to recycle, recover and reuse resources, waste is discarded with no value. Every year throughout the world, more than twenty-five million vehicles turn into end-of-life vehicles (ELV) and most of their valuable resources end up in landfill sites. This research analyses the effect of regulation on ELV innovation for additional recovery of resources in Japan and EU nations using patent data as a proxy. The analysis determines the statistical difference in patent activity before and after regulations were enacted in the case studies. The relevant data on ELV technologies was gathered for the period 1985-2013. The study suggests that in general environmental regulation in Japan drove innovation and reveals that environmental policy in Japan was more effective in enabling innovation compared to EU nations. Specifically, the results from these developed countries can be used by the rapidly growing developing countries in automobile manufacturing like China for amendment of their ELV regulation accordingly.

    Full Text Available Development of effective policy responses to address complex public health problems can be challenged by a lack of clarity about the interaction of risk factors driving the problem, differing views of stakeholders on the most appropriate and effective intervention approaches, a lack of evidence to support commonly implemented and acceptable intervention approaches, and a lack of acceptance of effective interventions. Consequently, political considerations, community advocacy and industry lobbying can contribute to a hotly contested debate about the most appropriate course of action; this can hinder consensus and give rise to policy resistance. The problem of alcohol misuse and its associated harms in New South Wales (NSW, Australia, provides a relevant example of such challenges. Dynamic simulation modelling is increasingly being valued by the health sector as a robust tool to support decision making to address complex problems. It allows policy makers to ask ‘what-if’ questions and test the potential impacts of different policy scenarios over time, before solutions are implemented in the real world. Participatory approaches to modelling enable researchers, policy makers, program planners, practitioners and consumer representatives to collaborate with expert modellers to ensure that models are transparent, incorporate diverse evidence and perspectives, are better aligned to the decision-support needs of policy makers, and can facilitate consensus building for action. This paper outlines a procedure for embedding stakeholder engagement and consensus building in the development of dynamic simulation models that can guide the development of effective, coordinated and acceptable policy responses to complex public health problems, such as alcohol-related harms in NSW.

  6. Telemetry: Summary of concept and rationale

    Science.gov (United States)

    1987-12-01

    This report presents the concept and supporting rationale for the telemetry system developed by the Consultative Committee for Space Data Systems (CCSDS). The concepts, protocols and data formats developed for the telemetry system are designed for flight and ground data systems supporting conventional, contemporary free-flyer spacecraft. Data formats are designed with efficiency as a primary consideration, i.e., format overhead is minimized. The results reflect the consensus of experts from many space agencies. An overview of the CCSDS telemetry system introduces the notion of architectural layering to achieve transparent and reliable delivery of scientific and engineering sensor data (generated aboard space vehicles) to users located in space or on earth. The system is broken down into two major conceptual categories: a packet telemetry concept and a telemetry channel coding concept. Packet telemetry facilitates data transmission from source to user in a standardized and highly automated manner. It provides a mechanism for implementing common data structures and protocols which can enhance the development and operation of space mission systems. Telemetry channel coding is a method by which data can be sent from a source to a destination by processing it in such a way that distinct messages are created which are easily distinguishable from one another. This allows construction of the data with low error probability, thus improving performance of the channel.

    Since natural and artificially-initiated (or "triggered") lightning are demonstrated hazards to the launch of space vehicles, the American space program has responded by establishing a set of Lightning Flight Commit Criteria (LFCC), also known as Lightning Launch Commit Criteria (LLCC), and associated Definitions to mitigate the risk. The LLCC apply to all Federal Government ranges and similar LFCC have been adopted by the Federal Aviation Administration for application at state-operated and private spaceports. The LLCC and Definitions have been developed, reviewed, and approved over the years of the American space program, progressing from relatively simple rules in the mid-twentieth century (that were inadequate) to a complex suite for launch operations in the early 21st century. During this evolutionary process, a "Lightning Advisory Panel (LAP)" of top American scientists in the field of atmospheric electricity was established to guide it. Details of this process are provided in a companion document entitled "A History of the Lightning Launch Commit Criteria and the Lightning Advisory Panel for America s Space program" which is available as NASA Special Publication 2010-216283. As new knowledge and additional operational experience have been gained, the LFCC/LLCC have been updated to preserve or increase their safety and to increase launch availability. All launches of both manned and unmanned vehicles at all Federal Government ranges now use the same rules. This simplifies their application and minimizes the cost of the weather infrastructure to support them. Vehicle operators and Range safety personnel have requested that the LAP provide a detailed written rationale for each of the LFCC so that they may better understand and appreciate the scientific and operational justifications for them. This document provides the requested rationales

    Assuming that the functional area for vehicles with combustion engines will be limited in some densely populated areas in the coming years and that improved expansion possibilities are also available for alternative drive and vehicle concepts such as the electric vehicle, this vehicle technology promises to develop very interesting potentials in terms of environmental and traffic technology. Until an unforeseeable time electric vehicles will continue to be technically down-graded vehicles with a high fun factor which can also be used in environmentally sensitive areas. The limitation in use forces the user to combine and to carry out the own route plan with other traffic carriers. Conventional automobiles are autarkic means of traffic in the functional area that has been provided so far. Electric vehicles can only be used in a co-operative traffic network and thus provide an important link for a realistic change in traffic policy that is not any longer supported by moral but by use-orientated arguments.

  14. Does Driving Range of Electric Vehicles Influence Electric Vehicle Adoption?

    2017-10-01

    Full Text Available This study aims to determine the influential factors on the market share of electric vehicles through panel data analysis based on time series data from 2011 to 2015 in 31 countries. We selected five significant independent variables that are expected to affect electric vehicle adoption based on literature review. The econometric model in this study suggests that the relative price of electric vehicle compared to internal combustion engine vehicle, driving range, and number of models available in markets are correlated to the market share of electric vehicles. On the other hand, relationship between recharging infrastructure—an important factor for electric vehicle adoption in many studies—and market share of electric vehicles turned out to be insignificant in this study. From a political point of view, we argue that policy makers need to allocate more resources to research and development in order to extend driving range at the early stage of electric vehicle deployment in the markets.

    2009-08-15

    This paper discussed the market transformations needed for the mass adoption of electric vehicles on Prince Edward Island (PEI) by the year 2030. The benefits of widespread electric vehicle use were also investigated. Results of the study indicated that 18,726 electric vehicles could be in use on the island by 2030, assuming a 24 per cent consumer adoption rate. Use of the vehicles would result in a reduction of greenhouse gases (GHGs) of up to 115 kilotonnes of carbon dioxide (CO{sub 2}), a 7 per cent decrease from current total energy related emissions. The annual electricity supply needed to power 78,024 electric cars and light trucks was estimated at between 200 GWh to 300 GWh. The complete adoption of electric vehicles in the province will results in GHG emissions reduction of up to 479 kilotonnes of CO{sub 2} annually, a 31 per cent decrease from current total energy related emissions. It was estimated that between 26 to 39 large wind turbines may provide sufficient power output for 78,024 electric vehicles.

  20. Macular Edema - Rationale for Therapy.

    Wolfensberger, Thomas J

    2017-01-01

    Macular edema represents the end-stage of multiple pathophysiological pathways in a multitude of ocular vascular, inflammatory, and other diseases. The rationale for clinical treatment of macular edema is based on the understanding and the inhibition of these pathophysiological mechanisms. When macular edema is caused by a generalized health problem such as diabetes, high blood pressure, or generalized inflammatory conditions, treatment of these generalized diseases can in many cases cure macular edema directly. In ocular diseases, the local exudation of fluid from blood vessels is governed by Starling's law as well as by intricate cellular mechanisms linked to the tight junctions in the inner and outer blood-retinal barrier. Drugs used in clinical practice, such as nonsteroidal anti-inflammatory drugs, corticosteroids, carbonic anhydrase inhibitors, and anti-vascular endothelial growth factor agents, all act in one way or another through these cellular mechanisms. Novel treatments such as neuroprotective agents like nerve growth factors, somatostatins and antiapoptotic agents like calpain, the glutamate blocker memantine, and different caspase inhibitors may in the future inhibit neuronal cell death in the retina by separate pathways. Using dimmed nocturnal illumination may be an additional novel method to reduce hypoxic stress during dark adaptation of the rod photoreceptors in diabetes. Successful surgical treatment of macular edema using vitrectomy and peeling relies, apart from the evident release of vitreomacular traction, on many other cellular and biochemical mechanisms activated by the surgery such as oxygenation of the inner retina, removal of the posterior hyaloid as a growth factor sink, and possible Müller cell remodeling with fluid redirection after internal limiting membrane peeling. © 2017 S.

  6. How important is vehicle safety in the new vehicle purchase/lease process for fleet vehicles?

    Science.gov (United States)

    Koppel, Sjaanie; Charlton, Judith; Fildes, Brian

    2007-06-01

    Despite the potential benefits that fleet vehicle purchase decisions could have on road safety, the role that vehicle safety plays in fleet managers' purchase decisions is poorly understood. In this study, fleet managers from Sweden and Spain completed a questionnaire regarding the importance of vehicle safety in the new vehicle purchase/lease process and the importance that is placed on safety options/features relative to other convenience and comfort features. The findings of the current study suggest that vehicle safety is generally not the primary consideration in the vehicle purchase process and is consistently outranked by factors such as price and dependability/reliability. For example, when asked to indicate the vehicle factors that are included in their company's criteria for purchasing/leasing a new vehicle, fleet managers from both Sweden and Spain were more likely to list the vehicle's price, reliability, running costs, size, and fuel consumption than the vehicle's safety (defined as the vehicle's EuroNCAP rating/other safety reports). In addition, the findings of this study suggest that the importance of vehicle safety did not differ across the two countries. For example, there was no significant difference in the proportion of fleet managers who indicated that EuroNCAP ratings were part of their official policy across the two countries. The findings highlighted the need to educate fleet managers about vehicle safety in the new vehicle purchase/lease process. In addition, vehicle safety information, such as EuroNCAP results or other crash test results need to be promoted more widely and effectively so that they play a more prominent role in their new vehicle choices.

  13. Comparative costs and benefits of hydrogen vehicles

    Energy Technology Data Exchange (ETDEWEB)

    Berry, G.D. [Lawrence Livermore National Lab., CA (United States)

    1996-10-01

    The costs and benefits of hydrogen as a vehicle fuel are compared to gasoline, natural gas, and battery-powered vehicles. Costs, energy, efficiency, and tail-pipe and full fuel cycle emissions of air pollutants and greenhouse gases were estimated for hydrogen from a broad range of delivery pathways and scales: from individual vehicle refueling systems to large stations refueling 300 cars/day. Hydrogen production from natural gas, methanol, and ammonia, as well as water electrolysis based on alkaline or polymer electrolytes and steam electrolysis using solid oxide electrolytes are considered. These estimates were compared to estimates for competing fuels and vehicles, and used to construct oil use, air pollutant, and greenhouse gas emission scenarios for the U.S. passenger car fleet from 2005-2050. Fuel costs need not be an overriding concern in evaluating the suitability of hydrogen as a fuel for passenger vehicles. The combined emissions and oil import reduction benefits of hydrogen cars are estimated to be significant, valued at up to {approximately}$400/yr for each hydrogen car when primarily clean energy sources are used for hydrogen production. These benefits alone, however, become tenuous as the basis supporting a compelling rationale for hydrogen fueled vehicles, if efficient, advanced fossil-fuel hybrid electric vehicles (HEV`s) can achieve actual on-road emissions at or below ULEV standards in the 2005-2015 timeframe. It appears a robust rationale for hydrogen fuel and vehicles will need to also consider unique, strategic, and long-range benefits of hydrogen vehicles which can be achieved through the use of production, storage, delivery, and utilization methods for hydrogen which are unique among fuels: efficient use of intermittent renewable energy sources, (e,g, wind, solar), small-scale feasibility, fuel production at or near the point of use, electrolytic production, diverse storage technologies, and electrochemical conversion to electricity.

  19. Ethical implications of co-benefits rationale within climate change mitigation strategy

    Directory of Open Access Journals (Sweden)

    Rita Vasconcellos Oliveira

    2016-10-01

    Full Text Available Climate change mitigation effort is being translated into several actions and discourses that make collateral benefits and their rationale increasingly relevant for sustainability, in such a way that they are now a constant part of the political agenda. Taking a border and consensual perspective, co-benefits are considered here to be emerging advantages of the implementation of measures regarding the lowering of greenhouse gases.Departing from the analysis of policy documents referring to two European urban transportation strategies, the emergent co-benefits are problematized and discussed to better understand their moral aspect. Further ethical reflection is conducted after an analysis of some unintended consequences of co-benefits rationale coming from the mentioned examples. The focus is primarily on the challenges of an integrative moral justification for co-benefits and also for their role in the climate change mitigation effort. We also discuss the limitations of the current normative models that frame co-benefits rationale, from a moral viewpoint and in relation to the overall climate change mitigation strategy.In this article, we propose the concepts of well-being and freedom, as portrayed by Capabilities Approach, as possible guiding notions for the moral and social evaluation of goodness of these emergent benefits and their rationale too. Additionally, some preliminary conclusions are drawn regarding the potential of the presented concepts to favour the climate change mitigation action. Finally, a scenario is drawn where Capabilities Approach is the moral guideline for co-benefits rationale showing this way its potential in terms of enhancing climate change mitigation strategy.

  20. Abandoned vehicles

    Relations with the Host States Service

    2004-01-01

    The services in charge of managing the CERN site have recently noted an increase in the number of abandoned vehicles. This poses a risk from the point of view of safety and security and, on the eve of several important events in honour of CERN's fiftieth anniversary, is detrimental to the Organization's image. Owners of vehicles that have been left immobile for some time on the CERN site, including on the external car park by the flags, are therefore invited to contact the Reception and Access Control Service (service-parking-longterm@cern.ch) before 1st October 2004 and, where appropriate, move their vehicle to a designated long-term parking area. After this date, any vehicle whose owner has failed to respond to this request and which is without a number plate, has been stationary for several weeks or is out of service, may be impounded at the owner's risk and expense.

  3. Global Trends in Immigration Detention and Alternatives to Detention: Practical, Political and Symbolic Rationales

    Directory of Open Access Journals (Sweden)

    Robyn Sampson

    2013-10-01

    Full Text Available Immigration detention is a growing threat to the well-being of migrants worldwide. While the use of this tool continues to increase, there is a growing consensus by governments on the need to pursue alternative programs. This paper examines the nature of these apparently contradictory developments and the reasons for tension in this area of migration policy. Drawing from research conducted by the International Detention Coalition and La Trobe University, this paper describes the Community Assessment and Placement (CAP model, which seeks to prevent unnecessary detention, while allowing governments to meet the rationale offered for detention. It argues that the global trends of growth in detention and an increased emphasis on alternatives reflect competing political, policy and operational objectives.  For example, governments wish to ensure compliance with deportation orders; alleviate political pressures regarding the harms associated with detention; and demonstrate control of territorial borders. Understanding the multiple rationales that shape this area of migration policy can help make sense of contradictory policy developments and identify the most effective ways to safeguard those who might be subject to detention.  

  4. Telework rationale and implementation for people with disabilities: considerations for employer policymaking.

    Moon, Nathan W; Linden, Maureen A; Bricout, John C; Baker, Paul M A

    2014-01-01

    Telework has been promoted as a viable workplace accommodation for people with disabilities since the 1990s, when information and communication technologies (ICT) had developed sufficiently to facilitate its widespread adoption. This initial research and accompanying policy recommendations were prescriptive in nature and frequently aimed at employers. This article adds to existing policy models for facilitating successful telework outcomes for people with disabilities. Drawing upon two studies by the Rehabilitation Engineering Research Center on Workplace Accommodations, we expound on employee-side considerations in the implementation of telework. Our policy model utilizes established typologies for policy evaluation to develop a process model that considers rationales and implementation factors for telework among people with physical disabilities. Telework may be used as an accommodation for disability, but employee rationales for telework are more complex, involving work-life balance, strategies for pain and fatigue not formally recognized as disability, and expediency in travel and transportation. Implementation of telework as a component of workplace operations is similarly multifaceted, involving non-technology accommodations to realize job restructuring left incomplete by telework. Our model grounds new empirical research in this area. We also renew our call for additional research on effective telework practices for people with disabilities.

    Little is understood about how the public perceives exposure-based therapy (ET) for treating anxiety and trauma-related disorders or how ET rationales affect treatment credibility. Distinct approaches to framing ET are practiced, including those emphasized in traditional cognitive behavioral therapy, acceptance and commitment therapy, and the more recent inhibitory learning model. However, their relative effect on ET's credibility remains unknown. A final sample of 964 U.S. adults provided baseline views of ET. Participants rated ET treatment credibility following a simple ET definition (pre-rationale) and following randomization to rationale modules addressing ET goals, fear, and cognitive strategies from distinct theoretical perspectives (post-rationale). Baseline ET views, symptoms, and sociodemographic characteristics were examined as putative moderators and predictors. At baseline, the majority had never heard of ET. From pre- to post-rationale, ET treatment credibility significantly increased but the rationales' theoretical perspective had little impact. More negative baseline ET views, specific ethnic/racial minority group status, and lower education moderated or predicted greater increases in treatment credibility following the rationale. ET remains relatively unknown as a treatment for anxiety or trauma, supporting the need for direct-to-consumer marketing. Diverse theory-driven rationales similarly increased ET credibility, particularly among those less likely to use ET. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The experiment on 83 rats has provided a rationale for the use of enterosorbents in acute ethanol intoxication. Polysorb reduces the halflife of ethanol, recovers physical fitness in the animals with acute poisoning. The enterosorbents polysorb, litovit, and sapropel have been found to have a corrective effect on the level of the major plasma antioxidant ceruloplasmin in acute ethanol intoxication. Enterosorbents are an effective detoxifying agent in this condition. Examining the mechanisms of toxic action of ethanol allows the most expedient treatment policy to be substantiated in acute poisonings.

  1. Why Are Cultural Policy Decisions Communicated in Cool Cash?

    Bille, Trine; Grønholm, Adam; Møgelgaard, Jeppe

    2016-01-01

    In this article, we analyze the role of the economic rationale in modern cultural policy decision communication and ask why it remains such an important factor, even though research has argued against it. Based on Luhmann’s system theory, we show how the economic rationale manifests itself...... complexity which the communicating cultural politician faces and must handle. As our analysis shows, this complexity is handled by communicating within the economic rationale and coding, with the result that complexity is reduced....... in the cultural political communication as parasitic and complementary couplings, and how different communication forms are in play: the indirect, direct, and the both-and form. The point is to construct communicative positions in cultural policy. The positions involve the economic rationale in their own...

    Davis, Stacy Cagle [ORNL; Boundy, Robert Gary [ORNL; Diegel, Susan W [ORNL

    2012-02-01

    This report details the major trends in U.S. light-duty vehicle and medium/heavy truck markets as well as the underlying trends that caused them. This report is supported by the U.S. Department of Energy s (DOE) Vehicle Technologies Program (VTP), and, in accord with its mission, pays special attention to the progress of high-efficiency and alternative-fuel technologies. This third edition since this report was started in 2008 offers several marked improvements relative to its predecessors. Most significantly, where earlier editions of this report focused on supplying information through an examination of market drivers, new vehicle trends, and supplier data, this edition uses a different structure. After opening with a discussion of energy and economics, this report features a section each on the light-duty vehicle and heavy/medium truck markets, and concluding with a section each on technology and policy. In addition to making this sectional re-alignment, this year s edition of the report also takes a different approach to communicating information. While previous editions relied heavily on text accompanied by auxiliary figures, this third edition relies primarily on charts and graphs to communicate trends. Any accompanying text serves to introduce the trends communication by the graphic and highlight any particularly salient observations. The opening section on Energy and Economics discusses the role of transportation energy and vehicle markets on a national (and even international) scale. For example, Figures 11 through 13 discuss the connections between global oil prices and U.S. GDP, and Figures 20 and 21 show U.S. employment in the automotive sector. The following section examines Light-Duty Vehicle use, markets, manufacture, and supply chains. Figures 26 through 33 offer snapshots of major light-duty vehicle brands in the U.S. and Figures 38 through 43 examine the performance and efficiency characteristics of vehicles sold.

    Full Text Available Instructors searching for learning objects in online repositories will be guided in their choices by the content of the object, the characteristics of the learners addressed, and the learning process embodied in the object. We report here on a feasibility study for metadata to record process-oriented information about instructional approaches for learning objects, though a set of Educational Rationale [ER] tags which would allow authors to describe the critical elements in their design intent. The prototype ER tags describe activities which have been demonstrated to be of value in learning, and authors select the activities whose support was critical in their design decisions. The prototype ER tag set consists descriptors of the instructional approach used in the design, plus optional sub-elements for Comments, Importance and Features which implement the design intent. The tag set was tested by creators of four learning object modules, three intended for post-secondary learners and one for K-12 students and their families. In each case the creators reported that the ER tag set allowed them to express succinctly the key instructional approaches embedded in their designs. These results confirmed the overall feasibility of the ER tag approach as a means of capturing design intent from creators of learning objects. Much work remains to be done before a usable ER tag set could be specified, including evaluating the impact of ER tags during design to improve instructional quality of learning objects.

  7. Rationale for a Program in Community Ophthalmology

    Bath, Patricia E.

    1979-01-01

    The high incidence of eye abnormalities among blacks, coupled with the relative unavailability of ophthalmic services, has resulted in excessive rates of blindness otherwise preventable or curable. As a consequence, incidence rates for blindness are higher for the black population than the white population. Statistics show that black children requiring eyeglasses are less likely to receive eyeglasses than similar age-matched white children. In virtually every state surveyed, blacks were more frequently and severely afflicted with eye diseases and were less likely to receive treatment than whites. Yet, no programs exist in any state specifically targeted to promote eye care among blacks and reverse the ever-worsening trend. Additional data characterizing the scope of the problem shall be presented. An initial strategy for approaching the problem, namely, community ophthalmology, has been developed. Community ophthalmology represents a new discipline promoting eye health and blindness prevention through programs utilizing methodologies of public health, community medicine, and ophthalmology. Basically, the use of community ophthalmology strategies is critical to positive out-come, when given a population composed of blacks and other minorities who are chronically underserved with regard to all sectors of health. The evolution and rationale for these concepts are discussed from national, as well as international, perspectives. PMID:423288

  8. Rationale for Antioxidant Supplementation in Hemodialysis Patients

    Directory of Open Access Journals (Sweden)

    Morena Marion

    2001-01-01

    Full Text Available Oxidative stress, which results from an imbalance between reactive oxygen species (ROS production and antioxidant defense mechanisms, is now a well recognized pathogenic process in hemodialysis (HD patients that could be involved in dialysis-related pathologies such as accelerated atherosclerosis, amyloidosis and anemia. This review is aimed at evaluating the rationale for preventive intervention against oxidative damage during HD as well as the putative causal factors implicated in this imbalance. The antioxidant system is severely impaired in uremic patients and impairment increases with the degree of renal failure. HD further worsens this condition mainly by losses of hydrophilic unbound small molecular weight substances such as vitamin C, trace elements and enzyme regulatory compounds. Moreover, inflammatory state due to the hemo-incompatibility of the dialysis system plays a critical role in the production of oxidants contributing further to aggravate the pro-oxidant status of uremic patients. Prevention of ROS overproduction can be achieved by improvement of dialysis biocompatibility, a main component of adequate dialysis, and further complimented by antioxidant supplementation. This could be achieved either orally or via the extracorporeal circuit. Antioxidants such as vitamin E could be bound on dialyzer membranes. Alternatively, hemolipodialysis consisting of loading HD patients with vitamin C or E via an ancillary circuit made of vitamin E-rich liposomes may be used.

  9. Transcatheter intraarterial therapies: rationale and overview.

    Lewandowski, Robert J; Geschwind, Jean-Francois; Liapi, Eleni; Salem, Riad

    2011-06-01

    Transcatheter intraarterial therapies have proved valuable in the battle against primary and secondary hepatic malignancies. The unique aspects of all such therapies are their reduced toxicity profiles and highly effective tumor responses. These unique characteristics coupled with their minimally invasive nature provide an attractive therapeutic option in patients who may have previously had few alternatives. The concept of all catheter-based intraarterial therapies is to selectively deliver anticancer treatment to tumor(s). These therapies, which include transarterial embolization, intraarterial chemoinfusion, transarterial chemoembolization with or without drug-eluting beads, and radioembolization with use of yttrium 90, inflict lethal insult to tumors while preserving normal hepatic parenchyma. This is possible because hepatic neoplasms preferentially derive their blood supply from an arterial source while the majority of noncancerous liver is supplied by the portal vein. As part of the interventional oncology review series, in this article we describe the rationale behind each of these transcatheter therapies and provide a review of the existing medical literature.

    Science.gov (United States)

    Ehrlich, Carl F., Jr.

    1993-10-01

    Design approaches for new space transportation systems strive to lower the cost per flight at affordable lifecycle costs in the 2000 plus era. Achieving efficiency in all operational activities is a major goal for all future systems. The key design drivers are adequate margins, the use of airline/aircraft approaches to certification, and ease of maintenance via subsystem accessibility. These goals have driven the design of the Rockwell HL-20 personnel launch system (PLS) concept. The entire system, both the spacecraft and support systems, has been designed for maintainability and producibility in order to minimize life-cycle costs. In these studies, the aircraft/airline approach to aircraft certification and flightworthiness was used. The vehicle and vehicle subsystems are certified one time, and regular maintenance is scheduled to ensure that flightworthiness is maintained throughout the life of the system. The resulting system-design concept described here reflects these goals through design features that facilitate operations, manufacturing, maintenance, and inspection and overhaul.

    1981-02-01

    This study examined the role of contextual factors, such as assignment rationale, on the attitudinal effects of peer tutoring. Fourth-grade children engaged in brief tutoring experiences as either a tutor or tutee. Subjects received four rationales for being selected as tutor or tutee: (a) a competence rationale, (b) a physical characteristic rationale, (c) a chance rationale, or (d) no rationale. As predicted, tutors had more positive attitudes than tutees when they had been given a competence or physical characteristic rationale but not when the tutors were provided a chance rationale or no rationale. Additionally, the tutors' and tutees' attitudes were enhanced when no rationale was provided. Results are discussed in terms of their implications for a role-theory analysis of tutoring and their implications for applied programs.

  5. Climate Model Ensemble Methodology: Rationale and Challenges

    Science.gov (United States)

    Vezer, M. A.; Myrvold, W.

    2012-12-01

    A tractable model of the Earth's atmosphere, or, indeed, any large, complex system, is inevitably unrealistic in a variety of ways. This will have an effect on the model's output. Nonetheless, we want to be able to rely on certain features of the model's output in studies aiming to detect, attribute, and project climate change. For this, we need assurance that these features reflect the target system, and are not artifacts of the unrealistic assumptions that go into the model. One technique for overcoming these limitations is to study ensembles of models which employ different simplifying assumptions and different methods of modelling. One then either takes as reliable certain outputs on which models in the ensemble agree, or takes the average of these outputs as the best estimate. Since the Intergovernmental Panel on Climate Change's Fourth Assessment Report (IPCC AR4) modellers have aimed to improve ensemble analysis by developing techniques to account for dependencies among models, and to ascribe unequal weights to models according to their performance. The goal of this paper is to present as clearly and cogently as possible the rationale for climate model ensemble methodology, the motivation of modellers to account for model dependencies, and their efforts to ascribe unequal weights to models. The method of our analysis is as follows. We will consider a simpler, well-understood case of taking the mean of a number of measurements of some quantity. Contrary to what is sometimes said, it is not a requirement of this practice that the errors of the component measurements be independent; one must, however, compensate for any lack of independence. We will also extend the usual accounts to include cases of unknown systematic error. We draw parallels between this simpler illustration and the more complex example of climate model ensembles, detailing how ensembles can provide more useful information than any of their constituent models. This account emphasizes the

    Zhang, Ye; Marshall, Iain; Wallace, Byron C

    2016-11-01

    We present a new Convolutional Neural Network (CNN) model for text classification that jointly exploits labels on documents and their constituent sentences. Specifically, we consider scenarios in which annotators explicitly mark sentences (or snippets) that support their overall document categorization, i.e., they provide rationales. Our model exploits such supervision via a hierarchical approach in which each document is represented by a linear combination of the vector representations of its component sentences. We propose a sentence-level convolutional model that estimates the probability that a given sentence is a rationale, and we then scale the contribution of each sentence to the aggregate document representation in proportion to these estimates. Experiments on five classification datasets that have document labels and associated rationales demonstrate that our approach consistently outperforms strong baselines. Moreover, our model naturally provides explanations for its predictions.

  11. Collaborative Design Rationale And Social Creativity In Cultures Of Participation

    Directory of Open Access Journals (Sweden)

    Gerhard Fischer

    2011-01-01

    Full Text Available The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three case studies, and provides evidence that design rationale and creativity need not be at odds with each other. Coordinating and integrating collective design rationale and social creatively provide new synergies and opportunities, particularly amid complex, open-ended, and ill-defined design problems requiring contributions and collaboration of multiple stakeholders supported by socio-technical environments in cultures of participation.

    Torsion vehicle model test of Simple Structural Surfaces (SSS) model for automotive vehicle sedan is proposed in this paper to demonstrate the importance of providing continuous load path within the vehicle structures. The proposed approach is relatively easy to understand as compared to Finite Element Method (FEM). The results prove that the proposed vehicle model test is capable to show that a satisfactory load paths can five a sufficient structural stiffness within the vehicle structure. It is clearly observed that the global torsion stiffness reduces significantly when only one panel is removed from the complete SSS model. The results also five a food agreement with respect to the theoretical hypothesis as the structure is less stiff in torsion in an open section condition. The SSS model and the corresponding torsion test is obviously useful to give an overview of vehicle structural integrity. It can be potentially integrated with FEM to speed up the design process of automotive vehicle.

    Steva, Thomas; Stevens, Jennifer

    2016-01-01

    The Space Shuttle was developed by NASA to be a largely reusable launch system which could provide frequent access to low earth orbit. Like all previous launch systems, safe reentry for the crew and payload required the use of a thermal protection system (TPS). Unlike previous spacecraft though, the Shuttle's TPS was exposed from launch, making it sensitive to debris which could be generated by the vehicle on ascent. The most likely and potentially destructive source of debris was considered to be ice, which could build-up anywhere on the External Tank (ET) where there was exposed metal. Ice could form during ground operations after the cryogenic propellants had been loaded and then be knocked loose on ascent. In order to prevent both ice build-up and boil-off of the propellants, the entire ET and all protuberances (orbiter attach points, pressurization lines, propellant feed lines, etc.) were covered with a spray on foam insulation (SOFI) type TPS. Unfortunately the foam was also susceptible to liberation during ascent, and posed a debris risk of its own. During the early years of the Shuttle Program engineers spent a good deal of effort characterizing the amount of foam that was shed.

    Science.gov (United States)

    Etchegaray, M. I.

    1987-05-01

    A proposed mission to 1000 astronomical units (TAU) is under study by the Jet Propulsion Laboratory. Launch date for a TAU mission is likely to be well into the first decade of the 21st century. Study of TAU has focused on the technologies required to carry out this ambitious mission and the identification of preliminary scientific rationale for such a deep space flight. A 1-MW nuclear-powered electric propulsion (NEP) system forms the baseline method for achieving the high velocities required. A solar system escape velocity of 106 km/s is needed to propel the TAU vehicle to 1000 AU in 50 years. The NEP system must accelerate the vehicle for about ten years before this velocity is attained because of the extremely low thrust nature of the xenon-fueled ion engines. At the end of the thrusting phase the NEP system is jettisoned to allow the TAU spacecraft and science experiments to coast out to 1000 AU. Another important technology for TAU is advanced optical communication systems, which are envisioned for transmitting science data to Earth. A 1-m optical telescope combined with a 10-W laser transponder can transmit 20 kbps to a 10-m Earth-orbit-based telescope from 1000 AU.

  17. Mobility in Turkey. Electric Vehicles

    Energy Technology Data Exchange (ETDEWEB)

    Yazgan, M. [Embassy of the Kingdom of the Netherlands, Turan Gunes Bulvari, Hollanda Caddesi, No.5,06550 Yildiz-Ankara (Turkey)

    2013-01-15

    The purpose of this report is to provide information about electric vehicles (EVs) and e-mobility as an emerging market in Turkey. EVs receive attention from the Turkish government for a number of reasons: Turkey has a strong automotive industry and needs to follow the technological developments taking place regarding intelligent vehicles and intelligent transport systems, as well as electric transportation technologies. Secondly, a considerable amount of carbon emissions from motor vehicles is of great concern in relation to climate change. EVs might be an alternative which can break the dependence of Turkey on imported fuel that has a negative influence on its current account deficit (CAD). On top of these factors, the Prime Minister of Turkey has a desire to have a 'Local Brand Vehicle' before the 100th year of the establishment of the Republic in 2023 and preferably an 'EV'. EVs are included in the strategy documents and action plans of almost all ministries and public institutions. Among all ministries, the Ministry of Science, Industry and Technology (MoSI and T) takes a leading position. It holds bi-annual meetings with stakeholders to monitor and evaluate progress about the level of actualization of the identified policies on e-mobility. MoSI and T's related institution of the Scientific and Technological Research Council of Turkey (TUBITAK) co-ordinates the R and D activities and provides generous R and D incentives. EVs have been put on sale in Turkey in 2012 and are still very limited in number. Public institutions are taking the lead by converting their vehicle fleet to EVs. EVs are also more suitable for businesses/ duties with a fixed/short route; therefore it is expected that the growth of the sector will mainly come from the vehicle fleet of the public organisations and institutions, followed by the private vehicle fleet of companies, e.g. freight companies. Although there are some on-going test drives, it is not yet proven

    Geller, Marvin A.

    2004-02-01

    In December 2002, AGU Council voted to extend the lifetime of AGU's position statement, ``Climate Change and Greenhouse Gases,'' for one year until a new statement was prepared. A year later, Council voted unanimously to adopt a new statement, ``Human Impacts on Climate,'' that reflected advances in the relevant science since 1998 when the original statement was adopted (see Eos, 23 December 2003). The purposes of this article are to provide the rationale for this revision, and to explain the process for formulating and approving this new statement. Background material for this new AGU statement can be found in several sources. These include Ledley et al. [1999], IPCC [2001], NRC [2001], and CSSP [2003]. The statement itself is available at http://www.agu.org/sci_soc/policy/climate_change_position.html.

  1. How important is vehicle safety in the new vehicle purchase process?

    Science.gov (United States)

    Koppel, Sjaanie; Charlton, Judith; Fildes, Brian; Fitzharris, Michael

    2008-05-01

    Whilst there has been a significant increase in the amount of consumer interest in the safety performance of privately owned vehicles, the role that it plays in consumers' purchase decisions is poorly understood. The aims of the current study were to determine: how important vehicle safety is in the new vehicle purchase process; what importance consumers place on safety options/features relative to other convenience and comfort features, and how consumers conceptualise vehicle safety. In addition, the study aimed to investigate the key parameters associated with ranking 'vehicle safety' as the most important consideration in the new vehicle purchase. Participants recruited in Sweden and Spain completed a questionnaire about their new vehicle purchase. The findings from the questionnaire indicated that participants ranked safety-related factors (e.g., EuroNCAP (or other) safety ratings) as more important in the new vehicle purchase process than other vehicle factors (e.g., price, reliability etc.). Similarly, participants ranked safety-related features (e.g., advanced braking systems, front passenger airbags etc.) as more important than non-safety-related features (e.g., route navigation systems, air-conditioning etc.). Consistent with previous research, most participants equated vehicle safety with the presence of specific vehicle safety features or technologies rather than vehicle crash safety/test results or crashworthiness. The key parameters associated with ranking 'vehicle safety' as the most important consideration in the new vehicle purchase were: use of EuroNCAP, gender and education level, age, drivers' concern about crash involvement, first vehicle purchase, annual driving distance, person for whom the vehicle was purchased, and traffic infringement history. The findings from this study are important for policy makers, manufacturers and other stakeholders to assist in setting priorities with regard to the promotion and publicity of vehicle safety features

  8. ISRU Propellant Selection for Space Exploration Vehicles

    Science.gov (United States)

    Chen, Timothy T.

    2013-01-01

    Chemical propulsion remains the only viable solution as technically matured technology for the near term human space transportation to Lunar and Mars. Current mode of space travel requires us to "take everything we will need", including propellant for the return trip. Forcing the mission designers to carry propellant for the return trip limits payload mass available for mission operations and results in a large and costly (and often unaffordable) design. Producing propellant via In-Situ Resource Utilization (ISRU) will enable missions with chemical propulsion by the "refueling" of return-trip propellant. It will reduce vehicle propellant mass carrying requirement by over 50%. This mass reduction can translates into increased payload to enhance greater mission capability, reduces vehicle size, weight and cost. It will also reduce size of launch vehicle fairing size as well as number of launches for a given space mission and enables exploration missions with existing chemical propulsion. Mars remains the ultimate destination for Human Space Exploration within the Solar System. The Mars atmospheric consist of 95% carbon dioxide (CO2) and the presence of Ice (water) was detected on Mars surfaces. This presents a basic chemical building block for the ISRU propellant manufacturing. However, the rationale for the right propellant to produce via ISRU appears to be limited to the perception of "what we can produce" as oppose to "what is the right propellant". Methane (CH4) is often quoted as a logical choice for Mars ISRU propellant, however; it is believed that there are better alternatives available that can result in a better space transportation architecture. A system analysis is needed to determine on what is the right propellant choice for the exploration vehicle. This paper examines the propellant selection for production via ISRU method on Mars surfaces. It will examine propellant trades for the exploration vehicle with resulting impact on vehicle performance, size

    Full Text Available When creativity is taken as a long-term, complex, and collaborative activity, support for awareness is required for group members to monitor the development of ideas, track how these ideas became narrowed, and understand how alternatives are being implemented and integrated by colleagues. In this paper, we investigate the effects of exposing design rationale to convey awareness, specifically activity awareness, in group creativity. Through evaluating a prototype, we investigate status updates that convey design rationale, and to what consequences, in small groups in fully distributed collaboration. We found that status updates are used for a variety of purposes and that participants’ comments on their collaborators’ status updates provided feedback. Overall, results suggest that participants’ awareness about their collaborators’ future plans increased over time. Majority of participants found the status updates useful, particularly those with higher metacognitive knowledge. Based on our results, two design strategies for activity awareness are proposed.

    Full Text Available This paper presents a review of the rationale for the in vitro mineralization process, preparation methods, and clinical applications of mineralized collagen. The rationale for natural mineralized collagen and the related mineralization process has been investigated for decades. Based on the understanding of natural mineralized collagen and its formation process, many attempts have been made to prepare biomimetic materials that resemble natural mineralized collagen in both composition and structure. To date, a number of bone substitute materials have been developed based on the principles of mineralized collagen, and some of them have been commercialized and approved by regulatory agencies. The clinical outcomes of mineralized collagen are of significance to advance the evaluation and improvement of related medical device products. Some representative clinical cases have been reported, and there are more clinical applications and long-term follow-ups that currently being performed by many research groups.

    Barnett, Michael L

    2006-11-01

    This article reviews the rationale for incorporating effective antimicrobial mouthrinses into a daily oral hygiene regimen along with mechanical plaque control methods. The author reviewed studies demonstrating the essential etiologic role of a pathogenic dental plaque biofilm in the development of gingivitis, as well as studies indicating that most people fail to maintain a level of mechanical plaque control sufficient to prevent disease. In addition, he did a brief review of studies of oral microbial ecology that identified the oral mucosal tissues as a reservoir of bacteria that colonize tooth surfaces, and he summarized six-month clinical studies of marketed antimicrobial mouthrinse ingredients and products. There is a twofold rationale for daily use of antimicrobial mouthrinses: first, given the inadequacy of mechanical plaque control by the majority of people, as a component added to oral hygiene regimens for the control and prevention of periodontal diseases; second, as a method of delivering antimicrobial agents to mucosal sites throughout the mouth that harbor pathogenic bacteria capable of recolonizing supragingival and subgingival tooth surfaces, thereby providing a complementary mechanism of plaque control. The efficacy of several mouthrinse ingredients and products is supported by published six-month clinical trials. The daily use of an effective antiplaque/antigingivitis antimicrobial mouthrinse is well-supported by a scientific rationale and can be a valuable component of oral hygiene regimens.

    A modular space vehicle chassis may facilitate convenient access to internal components of the space vehicle. Each module may be removable from the others such that each module may be worked on individually. Multiple panels of at least one of the modules may swing open or otherwise be removable, exposing large portions of the internal components of the space vehicle. Such chassis architectures may reduce the time required for and difficulty of performing maintenance or modifications, may allow multiple space vehicles to take advantage of a common chassis design, and may further allow for highly customizable space vehicles.

    Full battery electric vehicles (BEVs) have become an important policy option to mitigate climate change, but there are major uncertainties in the scale and timing of market diffusion. Although there has been substantial work showing the potential energy and climate benefits of BEVs, demand-side factors, such as consumer behaviour, are less recognized in the debate. We show the importance of assessing BEV diffusion from an integrated perspective, focusing on key interactions between technology and behaviour across different scales, including power-system demand, charging infrastructure, vehicle performance, driving patterns and individual adoption behaviour.

    and their family from a crash, their traffic infringement history, and whether they had children. These findings are consistent with previous research that suggests that, though older consumers highlight the importance of safety features (i.e., seat belts, air bags, braking), they often downplay the role of safety in their vehicle purchasing process and are more likely to equate vehicle safety with the presence of specific vehicle safety features or technologies rather than the vehicle's crash safety/test results or crashworthiness. The findings from this study provide a foundation to support further research in this area that can be used by policy makers, manufacturers, and other stakeholders to better target the promotion and publicity of vehicle safety features to particular consumer groups (such as older consumers). Better targeted campaigns may help to emphasize the value of safety features and their role in reducing the risk of injury/death. If older consumers are better informed of the benefits of safety features when purchasing a vehicle, a further reduction in injuries and deaths related to motor vehicle crashes may be realized.

    2015-05-01

    Plato's cosmology influenced classical astronomy and religion, but was in turn influenced by the polytheistic context of its time. Throughout his texts, including the cosmological treatise Timaeus, and the discussions on the soul in the Phaedrus, Plato (c.428-c.348 BC) established what can be generalised as Platonic cosmological thought. An understanding of the philosophical and mythical levels of Platonic thought can provide a rationale for polytheistic and astrological worldviews, pointing to some cosmological continuity, alongside major shifts, from ancient Greek religion to the astrological thought of ancient astronomers such as Claudius Ptolemy.

  15. Glucocorticoid augmentation of prolonged exposure therapy: rationale and case report

    Directory of Open Access Journals (Sweden)

    Laura Pratchett

    2010-12-01

    Full Text Available Rationale: Prolonged exposure (PE therapy has been found to reduce symptoms of posttraumatic stress disorder (PTSD; however, it is difficult for many patients to engage fully in the obligatory retelling of their traumatic experiences. This problem is compounded by the fact that habituation and cognitive restructuring – the main mechanisms through which PE is hypothesized to work – are not instantaneous processes, and often require several weeks before the distress associated with imaginal exposure abates. Case reports: Two cases are described that respectively illustrate the use of hydrocortisone and placebo, in combination with PE, for the treatment of combat-related PTSD. Based on known effects of glucocorticoids on learning and memory performance, we hypothesized that augmentation with hydrocortisone would improve the therapeutic effects of PE by hastening “new” learning and facilitating decreases in the emotional impact of fear memories during the course of treatment. The veteran receiving hydrocortisone augmentation of PE displayed an accelerated and ultimately greater decline in PTSD symptoms than the veteran receiving placebo. Conclusions: While no general conclusion can be derived from comparison of two patients, the findings are consistent with the rationale for augmentation. These case reports support the potential for an appropriately designed and powered clinical trial to examine the efficacy of glucocorticoids in augmenting the effects of psychotherapy for PTSD.

    Pregnancy and the postpartum period have been suggested as important contributors to overweight and obesity among women. This paper presents the design, rationale, and baseline participant characteristics of a randomized controlled intervention trial to enhance weight loss in postpartum women who entered pregnancy overweight or obese. Active Mothers Postpartum (AMP) is based on the rationale that the birth of a child can be a teachable moment. AMP's primary objectives are to promote and sustain a reduction in body mass index (BMI) up to 2 years postpartum via changes in diet and exercise behavior, with a secondary aim to assess racial differences in these outcomes. Women in the intervention arm participate in ten physical activity group sessions, eight healthy eating classes, and six telephone counseling sessions over a 9-month period. They also receive motivational tools, including a workbook with recipes and exercises, a pedometer, and a sport stroller. Four hundred fifty women aged > or =18 (mean 30.9), with a BMI > or = 25 kg/m(2) (mean 33.0) at baseline (6 weeks postpartum) were enrolled; 45% of the final sample are black and 53% are white. Baseline characteristics by study arm and by race are presented. Our intervention is designed to be disseminated broadly to benefit the public health. Behavior change interventions based on principles of social cognitive theory, stage of readiness, and other models that coincide with a teachable moment, such as the birth of a child, could be important motivators for postpartum weight loss.

  17. Rationale for statistical characteristics of road safety parameters

    Directory of Open Access Journals (Sweden)

    Dormidontova Tatiana

    2017-01-01

    Full Text Available When making engineering decisions at the stage of designing auto-roads and man-made structures it is necessary to take into account the statistical variability of physical and mechanical characteristics of the used materials as well as the different effects on the structures. Thus the rationale for the statistical characteristics of the parameters that determine the reliability of roads and man-made engineering facilities is of particular importance.There are many factors to be considered while designing roads, such as natural climatic factors, the accidental effects of the operating loads, the strength and deformation characteristics of the materials, the geometric parameters of the structure, etc. which affect the strength characteristics of roads and man-made structures. The rationale for statistical characteristics of the parameters can help an engineer assess the reliability of the decision and the economic risk, as well as avoid making mistakes in the design of roads and man-made structures.However, some statistical characteristics of the parameters that define the reliability of a road and man-made structures play a key role in the design. These are the visibility distance in daytime for the peak curve, variation coefficient of radial acceleration, the reliability of visibility distance and other parameters.

    Full Text Available As occupant protection offered by new passenger vehicles has improved, there has been growing concern about the harm that some vehicle designs may inflict on occupants of other vehicles with which they collide. Preceding analyses of crash statistics have clearly demonstrated the incompatibility between passenger sedan cars (PS and pick-up trucks (PU involved in side impact crashes in British Columbia. A comparison of light truck and passenger car crashes in previous literature reveals that light truck vehicles inflict greater harm than passenger cars for a number of reasons including their greater weight, stiffer structure, and higher ride height. These features place occupants of passenger cars at a disadvantage should they be involved in a collision with a light truck vehicle. The injury risk for passenger sedan car occupants is greater than the risk for pick-up truck occupants in two-vehicle crashes (Odds Ratio (OR 1.87; 95% Confidence Interval (CI 1.38-2.52. In addition, the risk of vehicle damage severity was increased for passenger cars compared with pick-up trucks (write off vehicle-OR 5.35; 95% CI 3.75-7.63, severely damaged vehicles-OR 5.87; 95% CI 4.79–7.19, moderately damaged vehicles-OR 2.86; 95% CI 2.44–3.36. There is strong justification for injury prevention experts and policy makers to step up motor vehicle crash injury prevention advocacy by implementing evidence-based policies to reduce rates of injury as a result of passenger sedan cars and pick-up trucks involved in side impact crashes in the province of British Columbia.

  1. Energy harvesting water vehicle

    KAUST Repository

    Singh, Devendra

    2018-01-04

    An efficient energy harvesting (EEH) water vehicle is disclosed. The base of the EEH water vehicle is fabricated with rolling cylindrical drums that can rotate freely in the same direction of the water medium. The drums reduce the drag at the vehicle-water interface. This reduction in drag corresponds to an increase in speed and/or greater fuel efficiency. The mechanical energy of the rolling cylindrical drums is also transformed into electrical energy using an electricity producing device, such as a dynamo or an alternator. Thus, the efficiency of the vehicle is enhanced in two parallel modes: from the reduction in drag at the vehicle-water interface, and from capturing power from the rotational motion of the drums.

    2010-07-01

    Today, electric vehicles (EVs) are being proposed in China as one of the potential options to address the dramatically increasing energy demand from on-road transport. However, the mass use of EVs could involve multiple environmental issues, because EVs use electricity that is generated primarily from coal in China. We examined the fuel-cycle CO(2), SO(2), and NO(x) emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids. EVs do not promise much benefit in reducing CO(2) emissions currently, but greater CO(2) reduction could be expected in future if coal combustion technologies improve and the share of nonfossil electricity increases significantly. EVs could increase SO(2) emissions by 3-10 times and also double NO(x) emissions compared to gasoline vehicles if charged using the current electricity grid. In the future, EVs would be able to reach the NO(x) emission level of gasoline vehicles with advanced emission control devices equipped in thermal power plants but still increase SO(2). EVs do represent an effective solution to issues in China such as oil shortage, but critical policy support is urgently needed to address the environmental issues caused by the use of EVs to make EVs competitive with other vehicle alternatives.

  3. Technology Roadmap: Fuel Economy of Road Vehicles

    Energy Technology Data Exchange (ETDEWEB)

    2012-07-01

    This roadmap explores the potential improvement of existing technologies to enhance the average fuel economy of motorised vehicles; the roadmap’s vision is to achieve a 30% to 50% reduction in fuel use per kilometre from new road vehicles including 2-wheelers, LDV s and HDV s) around the world in 2030, and from the stock of all vehicles on the road by 2050. This achievement would contribute to significant reductions in GHG emissions and oil use, compared to a baseline projection. Different motorised modes are treated separately, with a focus on LDV s, HDV s and powered two-wheelers. A section on in-use fuel economy also addresses technical and nontechnical parameters that could allow fuel economy to drastically improve over the next decades. Technology cost analysis and payback time show that significant progress can be made with low or negative cost for fuel-efficient vehicles over their lifetime use. Even though the latest data analysed by the IEA for fuel economy between 2005 and 2008 showed that a gap exists in achieving the roadmap’s vision, cutting the average fuel economy of road motorised vehicles by 30% to 50% by 2030 is achievable, and the policies and technologies that could help meet this challenge are already deployed in many places around the world.

The celebratory tone of the video is consistent with a Community Partnered Participatory Research approach, a local variant of participatory action research, where study findings are celebrated by the partners, and dissemination efforts include approaches intended for general audiences, especially from low-income, low-literacy, minority communities, in addition to traditional academic products like peer-reviewed scientific manuscripts. The CPIC video offers a community perspective on the study results to our partners, the general public, other scientists and policy makers. We designed the video to teach community and healthcare partners how to adapt and implement the CPIC depression care model and to offer other community -academic partnerships an example of a non-traditional product developed for dissemination from an NIH-funded research study.

  5. Hydrogen vehicle fueling station

    Hydrogen fueling stations are an essential element in the practical application of hydrogen as a vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology which is the link between the local storage facility and the vehicle. Because most merchant hydrogen delivered in the US today (and in the near future) is in liquid form due to the overall economics of production and delivery, we believe a practical refueling station should be designed to receive liquid. Systems studies confirm this assumption for stations fueling up to about 300 vehicles. Our fueling station, aimed at refueling fleet vehicles, will receive hydrogen as a liquid and dispense it as either liquid, high pressure gas, or low pressure gas. Thus, it can refuel any of the three types of tanks proposed for hydrogen-powered vehicles -- liquid, gaseous, or hydride. The paper discusses the fueling station design. Results of a numerical model of liquid hydrogen vehicle tank filling, with emphasis on no vent filling, are presented to illustrate the usefulness of the model as a design tool. Results of our vehicle performance model illustrate our thesis that it is too early to judge what the preferred method of on-board vehicle fuel storage will be in practice -- thus our decision to accommodate all three methods.

  6. Alcohol-fueled vehicles: An alternative fuels vehicle, emissions, and refueling infrastructure technology assessment

    Energy Technology Data Exchange (ETDEWEB)

    McCoy, G.A.; Kerstetter, J.; Lyons, J.K. [and others

    1993-06-01

    Interest in alternative motor vehicle fuels has grown tremendously over the last few years. The 1990 Clean Air Act Amendments, the National Energy Policy Act of 1992 and the California Clean Air Act are primarily responsible for this resurgence and have spurred both the motor fuels and vehicle manufacturing industries into action. For the first time, all three U.S. auto manufacturers are offering alternative fuel vehicles to the motoring public. At the same time, a small but growing alternative fuels refueling infrastructure is beginning to develop across the country. Although the recent growth in alternative motor fuels use is impressive, their market niche is still being defined. Environmental regulations, a key driver behind alternative fuel use, is forcing both car makers and the petroleum industry to clean up their products. As a result, alternative fuels no longer have a lock on the clean air market and will have to compete with conventional vehicles in meeting stringent future vehicle emission standards. The development of cleaner burning gasoline powered vehicles has signaled a shift in the marketing of alternative fuels. While they will continue to play a major part in the clean vehicle market, alternative fuels are increasingly recognized as a means to reduce oil imports. This new role is clearly defined in the National Energy Policy Act of 1992. The Act identifies alternative fuels as a key strategy for reducing imports of foreign oil and mandates their use for federal and state fleets, while reserving the right to require private and municipal fleet use as well.

    -innovation policies in important ways. The paper argues that the evolutionary economic perspective entails a new policy rationale which not only puts more emphasis on greening of markets as a means towards reaching climate goals but also shifts the representation of the economy towards a more dynamic one. The policy...... and innovation policy areas are currently little aligned and have in fact been considered “opposites” until very recently. The paper seeks to identify how evolutionary economic theory, hitherto very little applied to the environmental area, may guide the development of climate policies and eco...

    2009-05-01

    The 2003 Bureau of Labor Statistics American Time Use Survey (ATUS) contains 438 distinct primary activity variables that can be analyzed with regard to how time is spent by Americans. The Compendium of Physical Activities is used to code physical activities derived from various surveys, logs, diaries, etc to facilitate comparison of coded intensity levels across studies. This article describes the methods, challenges, and rationale for linking Compendium estimates of physical activity intensity (METs, metabolic equivalents) with all activities reported in the 2003 ATUS. The assigned ATUS intensity levels are not intended to compute the energy costs of physical activity in individuals. Instead, they are intended to be used to identify time spent in activities broadly classified by type and intensity. This function will complement public health surveillance systems and aid in policy and health-promotion activities. For example, at least one of the future projects of this process is the descriptive epidemiology of time spent in common physical activity intensity categories. The process of metabolic coding of the ATUS by linking it with the Compendium of Physical Activities can make important contributions to our understanding of American's time spent in health-related physical activity.

    Sex and gender differences are often overlooked in research design, study implementation and scientific reporting, as well as in general science communication. This oversight limits the generalizability of research findings and their applicability to clinical practice, in particular for women but also for men. This article describes the rationale for an international set of guidelines to encourage a more systematic approach to the reporting of sex and gender in research across disciplines. A panel of 13 experts representing nine countries developed the guidelines through a series of teleconferences, conference presentations and a 2-day workshop. An internet survey of 716 journal editors, scientists and other members of the international publishing community was conducted as well as a literature search on sex and gender policies in scientific publishing. The Sex and Gender Equity in Research (SAGER) guidelines are a comprehensive procedure for reporting of sex and gender information in study design, data analyses, results and interpretation of findings. The SAGER guidelines are designed primarily to guide authors in preparing their manuscripts, but they are also useful for editors, as gatekeepers of science, to integrate assessment of sex and gender into all manuscripts as an integral part of the editorial process.

    Full Text Available The problem of recycling end of life automotive vehicles is serious worldwide. It is one of the most important streams of waste in developed countries. It has big importance as recycling potential of raw materials content in automotive vehicles is valuable. Different parts and assemblies after dismantling can also be reused in vehicles where replacement of specific component is necessary. Reuse of the components should be taken into consideration in selecting the vehicles dismantling strategy. It also complies with European Union policy concerning end of life vehicles (ELV. In the paper it is presented systematic approach to dismantling strategies including disassembly oriented on further reuse of components. It is focused on decision making and possible benefits calculation from economic and environmental point of view.

    2008-01-01

    With the headline 'Ecstasy Over The Counter' in a popular daily newspaper, the debate on drug policy officially entered the arena of the 2003 New South Wales (Australia) State Election. The debate resurfaced in the lead-up to the 2004 Australian Federal Election. This paper analyses the pre-election coverage of drug policy issues in four Australian newspapers. Four high-circulation daily newspapers were monitored for a one-month period prior to both elections and analysed for their coverage of drug policy, particularly with respect to the policy of the Greens. The newspapers took different perspectives on drug policy issues, with two framing it in emotive terms as a moral debate and two framing it as political manoeuvring. The newspapers focused upon emotive and sensationalist factors. They did not provide their readers with information or a rationale for the formulation of drug policy, be this from a harm minimisation or zero tolerance perspective.

    With the aim of reducing greenhouse gas emissions associated with the transportation sector, policy-makers are supporting a multitude of measures to increase electric vehicle adoption. The actual level of emission reduction associated with the electrification of the transport sector is dependent on the contexts that determine when and where drivers charge electric vehicles. This analysis contributes to our understanding of the degree to which a particular electricity grid profile, vehicle type, and charging patterns impact CO2 emissions from light-duty, plug-in electric vehicles. We present an analysis of emissions resulting from both battery electric and plug-in hybrid electric vehicles for four charging scenarios and five electricity grid profiles. A scenario that allows drivers to charge electric vehicles at the workplace yields the lowest level of emissions for the majority of electricity grid profiles. However, vehicle emissions are shown to be highly dependent on the percentage of fossil fuels in the grid mix, with different vehicle types and charging scenarios resulting in fewer emissions when the carbon intensity of the grid is above a defined level. Restricting charging to off-peak hours results in higher total emissions for all vehicle types, as compared to other charging scenarios.

    Disclosed are various seats for vehicles particularly military vehicles that are susceptible to attack by road-bed explosive devices such as land mines or improvised explosive devices. The seats often have rigid seat shells and may include rigid bracing for rigidly securing the seat to the chassis of the vehicle. Typically embodiments include channels and particulate media such as sand disposed in the channels. A gas distribution system is generally employed to pump a gas through the channels and in some embodiments the gas is provided at a pressure sufficient to fluidize the particulate media when an occupant is sitting on the seat.

  18. Rationale and Development of a Security Assurance Index with Application toward the Development of a World Risk Index

    M. M. Plum; G. A. Beitel, PhD

    2006-06-01

    Assurance categories were previously developed to support the Department of Homeland Security’s efforts in the mitigation of Cyber Control System events. Defined according to the risk of life and economic loss, the minimum range is designated by policy, whereas the maximum limit seems to be constrained only by limits and interdependencies of the event. Use of this life / assets scale has proven to be helpful in managing risk due to the scale's ease of use, communication, and understanding. Suggestions have been made that this scale could be applied to all events of terror, disaster, and calamity of an international scale, with equally good results. This paper presents the history of some existing scales of disaster and assurance, the rationale behind the development of the original Security Assurance Index, and our proposed scale of disaster and calamity as a World Risk Index.

  19. Motor Vehicles, Air Pollution, and Climate Change

    Science.gov (United States)

    Mark, Jason

    2000-04-01

    Despite years of technical progress, motor vehicles continue to be a leading cause of environmental damage in the United States. For example, today's cars and trucks are the largest source of air pollution in many urban areas. US motor vehicles also account for 25 percent of the nation's carbon emissions, more than most countries emit from all sources combined. Fortunately, a host of technical improvements are emerging that could go a long ways towards taking vehicles out of the pollution picture. In the near-term, improving on the century-old internal combustion engine can deliver much-needed incremental gains. But electric drive vehicles--whether powered by batteries, small engines in hybrid configuration, or fuel cells--ultimately offer the greatest promise. Such technologies could dramatically reduce energy use, greenhouse gas emissions, and key air pollutants. The bulk of technical attention in recent years has been focused on improving the passenger vehicle, which will be the dominant energy consumer in the transportation sector for years to come. But freight trucks are also of growing concern, both because their contribution to global warming is on the rise and because serious questions are being raised about the public health impact of diesel technology. As a result, heavy trucks are emerging as a priority issue. Capitalizing on the opportunity presented by new technologies will not only require continued technical innovation but also policy action. As research into improved engines, fuels, and drive systems bears fruit over the coming years, aggressive and prudent policies will ensure that these new options make it onto the road and deliver on their environmental promise.

    discussion of how a vehicle can be used as a new threat vector to penetrate secure facilities will be presented. This includes how a modern automobile can be used as the exploitation mechanism for nearby devices such as laptops, cell phones, and wireless access points. Additional discussion will highlight how vehicle security might impact transportation of nuclear material through remote exploitation of a moving vehicle. The final discussion will include what possible implications might be relative to the physical protection systems at nuclear facilities. The audience will also be given details regarding the complexity of attack, thus implying the likelihood of successful exploitation, and information on how such attacks may be mitigated. Emerging security products for automobiles will be discussed and other mitigation methods will be detailed (e.g. disabling vehicle cellular modems). As a result, the audience will have a greater understanding of how to add vehicle security as a part of a comprehensive nuclear security policy.Finally, this paper will highlight the similarities between CAN Bus and other broadcast serial bus networks such as Profibus or DeviceNet, helping educate the reader on how susceptible this type of networking is to nefarious attacks and how it might affect components connected to many different nuclear systems, including control systems, safety systems, emergency systems, and support systems.

  4. Essays on Environmental Economics and Policy

    Science.gov (United States)

    Walker, W. Reed

    A central feature of modern government is its role in designing welfare improving policies to address and correct market failures stemming from externalities and public goods. The rationale for most modern environmental regulations stems from the failure of markets to efficiently allocate goods and services. Yet, as with any policy, distributional effects are important there exist clear winners and losers. Despite the clear theoretical justification for environmental and energy policy, empirical work credibly identifying both the source and consequences of these externalities as well as the distributional effects of existing policies remains in its infancy. My dissertation focuses on the development of empirical methods to investigate the role of environmental and energy policy in addressing market failures as well as exploring the distributional implications of these policies. These questions are important not only as a justification for government intervention into markets but also for understanding how distributional consequences may shape the design and implementation of these policies. My dissertation investigates these questions in the context of programs and policies that are important in their own right. Chapters 1 and 2 of my dissertation explore the economic costs and distributional implications associated with the largest environmental regulatory program in the United States, the Clean Air Act. Chapters 3 and 4 examine the social costs of air pollution in the context of transportation externalities, showing how effective transportation policy has additional co-benefits in the form of environmental policy. My dissertation remains unified in both its subject matter and methodological approach -- using unique sources of data and sound research designs to understand important issues in environmental policy.

    Current methods of detecting caries, especially fissure caries, are inaccurate, causing some caries to go undetected until it has reached more advanced stages. Minimally invasive dentistry is a philosophy in which the goal of intervention to conserve healthy tooth structure. The authors review the rationale and role of air abrasion in successful practice in the 21st century that includes the philosophy of minimal intervention. This objective encompasses a range of clinical procedures that includes assessment of caries risk to reinforce patient self-help, early detection of the disease before lesion cavitation to fortify the oral environment, restoration of fissure caries with maximum retention of sound tooth structure and sealant placement in unaffected areas. This conservative approach minimizes the restoration/re-restoration cycle, thus benefiting the patient over a lifetime.

    2012-06-01

    Portal vein embolization (PVE) is a technique used before hepatic resection to increase the size of liver segments that will remain after surgery. This therapy redirects portal blood to segments of the future liver remnant (FLR), resulting in hypertrophy. PVE is indicated when the FLR is either too small to support essential function or marginal in size and associated with a complicated postoperative course. When appropriately applied, PVE has been shown to reduce postoperative morbidity and increase the number of patients eligible for curative intent resection. PVE is also being combined with other therapies in novel ways to improve surgical outcomes. This article reviews the rationale, technical considerations, and current use of preoperative PVE.

    The great controversy surrounding the treatment of localized prostate cancer is related with its possibilities of radical treatment or active surveillance. The objective of this paper is to analyze the rationale selection among current focal therapy modalities regarding tumor and patient selection. Current articles about advantages and disadvantages on the treatment of localized prostate cancer as well as information about focal therapy regarding tumour selection, characteristics and indications cited in MEDLINE search were reviewed. Focal therapy standardized criteria must be: low risk tumors, PSA15. Focal therapy is an alternative for localized prostate cancer treatment. However, some aspects of their diagnosis and selection criteria should be defined by prospective studies which should provide knowledge about the indication for focal therapy. Copyright © 2013 AEU.

    2013-01-01

    Arthroscopic surgery has been widely used for treatment of temporomandibular joint (TMJ) internal derangements and diseases for the last 40 years. Although 626 articles have been hit by Pubmed search in terms of “TMJ arthroscopic surgery”, this review article is described based on distinguished publishing works and on my experiences with TMJ arthroscopic surgery and related research with an aim to analyse the rationale of arthroscopic surgeries of the temporomandibular joint. With arthrocentesis emerging as an alternative, less invasive, treatment for internal derangement with closed lock, the primary indication of arthroscopic surgery seems to be somewhat limited. However, the value of endoscopic inspection and surgery has its position for both patient and physician with its long-term reliable results. PMID:25737901

    The expansion of employment-centered family policies of the Grand Coalition in Germany came with some surprise, as Christian Democrats have traditionally been strongly committed to the male breadwinner model and corresponding family policies. This article investigates why Christian Democrats (though with some inconsistencies) promoted “social-democratic” family policies guided by the adult worker rather than by the male breadwinner model. Illuminating the politics of recent family policy reforms, the electoral rationale for this modernization of family policy, the role of political entrepreneurship, and intraparty political conflicts over the new policy paradigm are discussed.

  12. Homeschooling in the United States: Examining the Rationales for Individualizing Education

    Directory of Open Access Journals (Sweden)

    T. Jameson Brewer

    Full Text Available Abstract This article provides an exploratory overview of the history of homeschooling in the United States in addition to examining some of the claims made by advocacy organizations. There are two broad categories of rationales for homeschooling: (1 empirical — claims of greater efficiency, effectiveness, or pedagogical appropriateness; and (2 ideological – often informed by a religious or political disposition. A detailed discussion of both rationales is provided. First examined are claims made by homeschooling advocates related to effectiveness and efficiency, finding that this rationale does not have the same validity that ideological rationales like religion and safety may have. Finally, these rationales are cast against the backdrop of the aims of education as a mechanism for the collective good or for the individual good.

Owners of vehicles that have been left immobile for some time on the CERN site, including on the external car park by the flags, are therefore invited to contact the Reception and Access Control Service (service-parking-longterm@cern.ch) before 1st October 2004 and, where appropriate, move their vehicle to a designated long-term parking area. After this date, any vehicle whose owner has failed to respond to this request and which is without a number plate, has been stationary for several weeks or is out of service, may be impounded at the owner's risk and expense.

  18. Aerodynamics of Small Vehicles

    Science.gov (United States)

    Mueller, Thomas J.

    In this review we describe the aerodynamic problems that must be addressed in order to design a successful small aerial vehicle. The effects of Reynolds number and aspect ratio (AR) on the design and performance of fixed-wing vehicles are described. The boundary-layer behavior on airfoils is especially important in the design of vehicles in this flight regime. The results of a number of experimental boundary-layer studies, including the influence of laminar separation bubbles, are discussed. Several examples of small unmanned aerial vehicles (UAVs) in this regime are described. Also, a brief survey of analytical models for oscillating and flapping-wing propulsion is presented. These range from the earliest examples where quasi-steady, attached flow is assumed, to those that account for the unsteady shed vortex wake as well as flow separation and aeroelastic behavior of a flapping wing. Experiments that complemented the analysis and led to the design of a successful ornithopter are also described.

    A method and apparatus for heating a catalytic converter's catalyst to an efficient operating temperature in a hybrid electric vehicle when the vehicle is in a charge limited mode such as e.g., the charge depleting mode or when the vehicle's high voltage battery is otherwise charge limited. The method and apparatus determine whether a high voltage battery of the vehicle is incapable of accepting a first amount of charge associated with a first procedure to warm-up the catalyst. If it is determined that the high voltage battery is incapable of accepting the first amount of charge, a second procedure with an acceptable amount of charge is performed to warm-up the catalyst.

    2007-05-08

    Revision 75 of the Tracked Vehicle software is a soft real-time simulation of a differentially steered, tracked mobile robot, which, because of the track flippers, resembles the iRobot PackBot (http://www.irobot.com/). Open source libraries are used for the physics engine (http://www.ode.org/), the display and user interface (http://www.mathies.com/cpw/), and the program command line and configuration file parameters (http://www.boost.org/). The simulation can be controlled by a USB joystick or the keyboard. The configuration file contains demonstration model parameters of no particular vehicle. This simulation can be used as a starting point for those doing tracked vehicle simulations. This simulation software is essentially a research tool which can be modified and adapted for certain types of tracked vehicle research. An open source license allows an individual researchers to tailor the code to their specific research needs.

    2012-01-01

    Vehicle Dynamics and Control provides a comprehensive coverage of vehicle control systems and the dynamic models used in the development of these control systems. The control system applications covered in the book include cruise control, adaptive cruise control, ABS, automated lane keeping, automated highway systems, yaw stability control, engine control, passive, active and semi-active suspensions, tire-road friction coefficient estimation, rollover prevention, and hybrid electric vehicle. In developing the dynamic model for each application, an effort is made to both keep the model simple enough for control system design but at the same time rich enough to capture the essential features of the dynamics. A special effort has been made to explain the several different tire models commonly used in literature and to interpret them physically. In the second edition of the book, chapters on roll dynamics, rollover prevention and hybrid electric vehicles have been added, and the chapter on electronic stability co...

    2012-01-01

    The Handbook of Intelligent Vehicles provides a complete coverage of the fundamentals, new technologies, and sub-areas essential to the development of intelligent vehicles; it also includes advances made to date, challenges, and future trends. Significant strides in the field have been made to date; however, so far there has been no single book or volume which captures these advances in a comprehensive format, addressing all essential components and subspecialties of intelligent vehicles, as this book does. Since the intended users are engineering practitioners, as well as researchers and graduate students, the book chapters do not only cover fundamentals, methods, and algorithms but also include how software/hardware are implemented, and demonstrate the advances along with their present challenges. Research at both component and systems levels are required to advance the functionality of intelligent vehicles. This volume covers both of these aspects in addition to the fundamentals listed above.

    Horne, J A; Reyner, L A

    1995-03-04

    To assess the incidence, time of day, and driver morbidity associated with vehicle accidents where the most likely cause was the driver falling asleep at the wheel. Two surveys were undertaken, in southwest England and the midlands, by using police databases or on the spot interviews. Drivers involved in 679 sleep related vehicle accidents. Of all vehicle accidents to which the police were summoned, sleep related vehicle accidents comprised 16% on major roads in southwest England, and over 20% on midland motorways. During the 24 hour period there were three major peaks: at around 0200, 0600, and 1600. About half these drivers were men under 30 years; few such accidents involved women. Sleep related vehicle accidents are largely dependent on the time of day and account for a considerable proportion of vehicle accidents, especially those on motorways and other monotonous roads. As there are no norms for the United Kingdom on road use by age and sex for time of day with which to compare these data, we cannot determine what the hourly exposure v risk factors are for these subgroups. The findings are in close agreement with those from other countries.

  12. An economic assessment of low carbon vehicles

    Energy Technology Data Exchange (ETDEWEB)

    Summerton, P. [Cambridge Econometrics CE, Cambridge (United Kingdom); Harrison, P. [European Climate Foundation ECF, Brussels (Belgium)] (eds.)

    2013-03-15

    The study aimed to analyse the economic impacts of decarbonizing light duty vehicles. As part of the study, the impacts of the European Commissions proposed 2020 CO2 regulation for cars and vans have been assessed. The analysis showed that a shift to low-carbon vehicles would increase spending on vehicle technology, therefore generating positive direct employment impacts, but potentially adding 1,000-1,100 euro to the capital cost of the average new car in 2020. However, these additional technology costs would be offset by fuel savings of around 400 euro per year, indicating an effective break-even point for drivers of approximately three years. At the EU level, the cost of running and maintaining the European car fleet would become 33-35 billion euro lower each year than in a 'do nothing scenario' by 2030, leading to positive economic impacts including indirect employment gains. Data on the cost of low carbon vehicle technologies has largely been sourced from the auto industry itself, with the study supported by a core working group including Nissan, GE, the European Association of Automotive Suppliers (CLEPA), and the European Storage Battery Manufacturers Association (Eurobat). Fuel price projections for the study were based on the IEA's World Energy Outlook, while technical modelling was carried out using the transport policy scoping tool SULTAN (developed by Ricardo-AEA for the European Commission) and the Road Vehicle Cost and Efficiency Calculation Framework, also developed by Ricardo-AEA. Macro-economic modelling was done using the E3ME model, which has previously been used for several European Commission and EU government impact assessments. This report focuses on efficient use of fossil fuels in internal combustion- and hybrid electric vehicles. It will be followed by a second report, which will focus on further reducing the use of fossil fuels by also substituting them with domestically produced energy carriers, such as electricity and

  13. Factors Influencing the Behavioural Intention towards Full Electric Vehicles: An Empirical Study in Macau

    Ivan K. W. Lai

    2015-09-01

    Full Text Available This study examines the factors that influence individual intentions towards the adoption of full electric vehicles. A sample including 308 respondents was collected on the streets of Macau. The collected data were analysed by confirmatory factor analysis and structural equation modelling. The results demonstrate that environmental concerns and the perception of environmental policy are antecedent factors of the perception of full electric vehicles, which influences the behavioural intention to purchase full electric vehicles. This study also finds that the perception of economic benefit is one of the key factors influencing the adoption of full electric vehicles. Vehicle operators seek economic benefits from future long-term fuel savings, high energy efficiency, and cheap electricity. Thus, a government striving to promote low-carbon transportation needs to scale up its efforts to enhance citizens’ environmental concerns and to establish proper environmental policy as well as to provide long-term financial and strategic support for electric vehicles.

    Mark L. Niebylski

    2014-03-01

    Full Text Available Unhealthy eating is the leading risk for death and disability globally. As a result, the World Health Organization (WHO has called for population health interventions. One of the proposed interventions is to ensure healthy foods are available by implementing healthy food procurement policies. The objective of this systematic review was to evaluate the evidence base assessing the impact of such policies. A comprehensive review was conducted by searching PubMed and Medline for policies that had been implemented and evaluated the impact of food purchases, food consumption, and behaviors towards healthy foods. Thirty-four studies were identified and found to be effective at increasing the availability and purchases of healthy food and decreasing purchases of unhealthy food. Most policies also had other components such as education, price reductions, and health interventions. The multiple gaps in research identified by this review suggest that additional research and ongoing evaluation of food procurement programs is required. Implementation of healthy food procurement policies in schools, worksites, hospitals, care homes, correctional facilities, government institutions, and remote communities increase markers of healthy eating. Prior or simultaneous implementation of ancillary education about healthy eating, and rationale for the policy may be critical success factors and additional research is needed.

    China's Launch Vehicle technologies have been started since 1950s. With the efforts made by several-generation Chinese Space people, the Long March (LM) Launch Vehicles, China's main space transportation tools, have undergone a development road from conventional propellants to cryogenic propellants, from stage-by-stage to strap-on, from dedicated-launch to multiple-launch, from satellite-launching to space capsule-launching. The LM Launch Vehicles are capable of sending various payloads to different orbits with low cost and high reliability. Till now, the LM Launch Vehicles have conducted 67 launch missions, putting 76 spacecraft into the given orbits since the successful mission made by LM-1 in 1970. Especially, they have performed 22 international commercial satellite-launching missions, sending 27 foreign satellites successfully. The footprints of LM Launch Vehicles reflect the development and progress of Chinese Space Industry. At the beginning of the 21st century, with the development of launch vehicle technology and the economic globalization, it is an inexorable trend that Chinese space industry must participate in the international cooperation and competition. Being faced with both opportunities and challenges, Chinese Space Industry should promote actively the commercial launch service market to increase service quality and improve the comprehensive competition capabilities. In order to maintain the sustaining development of China's launch vehicle technology and to meet the increasing needs in the international commercial launch service market, Chinese space industry is now doing research work on developing new-generation Chinese launchers. The new launchers will be large-scale, powerful and non-contamination. The presence of the new-generation Chinese launchers will greatly speed up the development of the whole space-related industries in China, as well as other parts of the world. In the first part, this paper gives an overview on China Aerospace Science

  1. Distributed Propulsion Vehicles

    Science.gov (United States)

    Kim, Hyun Dae

    2010-01-01

    Since the introduction of large jet-powered transport aircraft, the majority of these vehicles have been designed by placing thrust-generating engines either under the wings or on the fuselage to minimize aerodynamic interactions on the vehicle operation. However, advances in computational and experimental tools along with new technologies in materials, structures, and aircraft controls, etc. are enabling a high degree of integration of the airframe and propulsion system in aircraft design. The National Aeronautics and Space Administration (NASA) has been investigating a number of revolutionary distributed propulsion vehicle concepts to increase aircraft performance. The concept of distributed propulsion is to fully integrate a propulsion system within an airframe such that the aircraft takes full synergistic benefits of coupling of airframe aerodynamics and the propulsion thrust stream by distributing thrust using many propulsors on the airframe. Some of the concepts are based on the use of distributed jet flaps, distributed small multiple engines, gas-driven multi-fans, mechanically driven multifans, cross-flow fans, and electric fans driven by turboelectric generators. This paper describes some early concepts of the distributed propulsion vehicles and the current turboelectric distributed propulsion (TeDP) vehicle concepts being studied under the NASA s Subsonic Fixed Wing (SFW) Project to drastically reduce aircraft-related fuel burn, emissions, and noise by the year 2030 to 2035.

    An approach to overcome the accidental problem happens in the night, while the driver is drunk or feels sleepy. This system controls the speed of the vehicle at steep turns. It is designed, to provide the information to the driver, whether the next turn is right/left, is there any traffic jam or land sliding in the coming way. It also assists during heavy rains and mist conditions. It may be implemented by using computer or by using a dedicated microcontroller. If we have a group of vehicles connected with the system then we can locate them by using the cameras, at different places. Information regarding any vehicle can be transmitted anywhere using Internet provided at the monitoring system, so as to prevent accidents or provide information during any calamity.

  8. Dynamics of aerospace vehicles

    Schmidt, David K.

    1991-01-01

    The focus of this research was to address the modeling, including model reduction, of flexible aerospace vehicles, with special emphasis on models used in dynamic analysis and/or guidance and control system design. In the modeling, it is critical that the key aspects of the system being modeled be captured in the model. In this work, therefore, aspects of the vehicle dynamics critical to control design were important. In this regard, fundamental contributions were made in the areas of stability robustness analysis techniques, model reduction techniques, and literal approximations for key dynamic characteristics of flexible vehicles. All these areas are related. In the development of a model, approximations are always involved, so control systems designed using these models must be robust against uncertainties in these models.

    2017-01-01

    This book on the dynamics of rail vehicles is developed from the manuscripts for a class with the same name at TU Berlin. It is directed mainly to master students with pre-knowledge in mathematics and mechanics and engineers that want to learn more. The important phenomena of the running behaviour of rail vehicles are derived and explained. Also recent research results and experience from the operation of rail vehicles are included. One focus is the description of the complex wheel-rail contact phenomena that are essential to understand the concept of running stability and curving. A reader should in the end be able to understand the background of simulation tools that are used by the railway industry and universities today.

    Ma, Jun; Qian, Kun; Gong, Zaiyan

    2017-05-01

    The paper optimizes the original spacing policy when adopting VTH (Variable Time Headway), proposes to introduce the road curve curvature K to the spacing policy to cope with following the wrong vehicle or failing to follow the vehicle owing to the radar limitation of curve in ACC system. By utilizing MATLAB/Simulink, automobile longitudinal dynamics model is established. At last, the paper sets up such three common cases as the vehicle ahead runs at a uniform velocity, an accelerated velocity and hits the brake suddenly, simulates these cases on the curve with different curvature, analyzes the curve spacing policy in the perspective of safety and vehicle following efficiency and draws the conclusion whether the optimization scheme is effective or not.

    Public and private launch vehicle developers are reducing the cost of propulsion for small commercial launchers, but conventional high-performance, high-reliability avionics remain the disproportionately high cost driver for launch. AVA technology performs as well or better than conventional launch vehicle avionics, but with a fraction of the recurring costs. AVA enables small launch providers to offer affordable rides to LEO to nano-satellites as primary payloads meaning, small payloads can afford to specify their own launch and orbit parameters

    Piccoli, B; Soci, G; Zambelli, P L; Pisaniello, D

    2004-01-01

    The assessment of lighting conditions in workplaces has traditionally focused on the measurement of illuminance. The rationale for a new method for the detailed evaluation of natural and artificial light in 'near work' situations, involving the assessment of luminance, is described. The procedure comprises four successive phases: (1) identify object/images observed during work tasks; (2) outline the area of the operator's visual field where gaze is predominantly directed; (3) measure luminances in the visual field, pin-pointing all sources of primary and secondary luminance, and constructing iso-luminance maps; and (4) compare luminance ratios. The procedure was illustrated using the common example of near work in an office environment. Illuminance was found to be inadequate to evaluate the effects of natural and artificial environmental light in the workplace. This is due to the fact that the luxmeter is designed to integrate the light detected over a large angle, whereas in near work the operator's retina is mainly stimulated by light originating from objects/images placed in the occupational visual field. A detailed measurement of luminance within the occupational visual field is consistent with ocular anatomy and physiology, and can be used as part of a risk assessment for visual disturbances and to rationalize lighting at workstations.

  14. Glucocorticoid augmentation of prolonged exposure therapy: rationale and case report.

    Yehuda, Rachel; Bierer, Linda M; Pratchett, Laura; Malowney, Monica

    2010-01-01

    Prolonged exposure (PE) therapy has been found to reduce symptoms of posttraumatic stress disorder (PTSD); however, it is difficult for many patients to engage fully in the obligatory retelling of their traumatic experiences. This problem is compounded by the fact that habituation and cognitive restructuring - the main mechanisms through which PE is hypothesized to work - are not instantaneous processes, and often require several weeks before the distress associated with imaginal exposure abates. Two cases are described that respectively illustrate the use of hydrocortisone and placebo, in combination with PE, for the treatment of combat-related PTSD. Based on known effects of glucocorticoids on learning and memory performance, we hypothesized that augmentation with hydrocortisone would improve the therapeutic effects of PE by hastening "new" learning and facilitating decreases in the emotional impact of fear memories during the course of treatment. The veteran receiving hydrocortisone augmentation of PE displayed an accelerated and ultimately greater decline in PTSD symptoms than the veteran receiving placebo. While no general conclusion can be derived from comparison of two patients, the findings are consistent with the rationale for augmentation. These case reports support the potential for an appropriately designed and powered clinical trial to examine the efficacy of glucocorticoids in augmenting the effects of psychotherapy for PTSD.

    This paper outlines the economic rationale for investments that reduce stunting. We present a framework that illustrates the functional consequences of stunting in the 1000 days after conception throughout the life cycle: from childhood through to old age. We summarize the key empirical literature around each of the links in the life cycle, highlighting gaps in knowledge where they exist. We construct credible estimates of benefit-cost ratios for a plausible set of nutritional interventions to reduce stunting. There are considerable challenges in doing so that we document. We assume an uplift in income of 11% due to the prevention of one fifth of stunting and a 5% discount rate of future benefit streams. Our estimates of the country-specific benefit-cost ratios for investments that reduce stunting in 17 high-burden countries range from 3.6 (DRC) to 48 (Indonesia) with a median value of 18 (Bangladesh). Mindful that these results hinge on a number of assumptions, they compare favourably with other investments for which public funds compete. © 2013 John Wiley & Sons Ltd.

    2006-04-01

    The 2000 guidelines for cardiopulmonary resuscitation (CPR) recommend up to three sequential shocks for persistent ventricular fibrillation (VF). We hypothesized that the time consumed for repetitive rhythm analyses and recharging of the capacitor compromises the success of the second and third shock of each sequence. In 60 domestic pigs, VF was electrically induced and untreated for 7 min. After 1 min of CPR, which includes precordial compression and ventilation, up to three sequential shocks were delivered. All animals were resuscitated. For purposes of the present study we determined the outcomes of the first, the second, and the third shock of each sequence during attempted defibrillation. Our criterion of success was the restoration of spontaneous circulation (ROSC). Forty-eight of the 60 animals (80%) attained ROSC after the first shock, 9/60 (15%) after the second shock, and only 3/60 (5%) after the third shock. In confirmation of the earlier observations, ROSC was highly predictive when the coronary perfusion pressure (CPP) exceeded 12 mmHg and end-tidal CO(2) (ETCO(2)) exceeded 11 mmHg. However, these criteria were never achieved after the second shock. The present study supports the rationale of delivering only a single shock, or at the most two shocks, prior to resuming chest compression, to re-establish the threshold levels of CPP and ETCO(2) before delivery of a subsequent electrical shock.

    Arthritis causes disability due to pain and inflammation in joints. There are many forms of arthritis, one of which is osteoarthritis whose prevalence increases with age. It occurs in various joints including hip, knee and hand with knee osteoarthritis being more prevalent. There is no cure for it. The management strategies include exercise, glucosamine plus chondroitin sulfate and NSAIDs. In vitro and animal studies provide a rationale for the use of antioxidant supplements for its management. This review assesses the reality of the benefits of antioxidant supplements in the management of knee osteoarthritis. Several difficulties were encountered in examining this issue: poorly conducted studies, a lack of uniformity in disease definition and diagnosis, and muddling of conclusions from attempts to isolate the efficacious molecules. The antioxidant supplements with most evidence for benefit for pain relief and function in knee osteoarthritis were based on curcumin and avocado-soya bean unsaponifiables. Boswellia and some herbs used in Ayurvedic and Chinese medicine may also be useful. The benefits of cuisines with the appropriate antioxidants should be assessed because they may be more economical and easier to incorporate into the lifestyle.

    The transport sector globally is overly dependent on liquid fossil fuels. Electric vehicles (EVs) are touted as a way of diversifying the fuel mix and helping to reduce dependence on fossil fuels. There could also be other co-benefits of EVs, such as improved energy security, decarbonising...... to infrastructure and policies. While the literature on EVs has focused more on the role of electric cars, it could be electric two-wheelers which could make early headway, as is the case in China where nearly 120 million such vehicles had been sold by the end of 2012. Three scenarios (Business as Usual (BAU......), Electric Vehicles, and Electric Vehicles Plus 2°), for EVs from 2010 to 2050, are analysed using the bottom-up energy system ANSWER MARKAL model.

    2010-11-01

    Nowadays, policies are being developed in many countries in order to decrease their greenhouse gases emissions. While in this area some technologies are widely installed (hydro and solar energy), other ones, like the Wind energy could get an important role in the medium and long term. Coal, gas, diesel, atomic etc. are the basic Natural source of energy. The uses of these sources are also harmful to the nature because they produce the different types of pollution. On the other hand hydro and wind energy are Clean, Green, renewable energy and pollution free sources. Now a day's most of the Company manufactures the hybrid vehicles with the coordination. But they are suffering lot of limitation like the speed of the vehicle and travel distance by the vehicle. So here we have proposed the Electrical and wind energy coordination (EWEC) system. This system is highly useful to improve the overall performance of hybrid vehicle. This system is also 100% pollution free.

  1. Development of a Publicly Available, Comprehensive Database of Fiber and Health Outcomes: Rationale and Methods.

    Directory of Open Access Journals (Sweden)

    Kara A Livingston

    Full Text Available Dietary fiber is a broad category of compounds historically defined as partially or completely indigestible plant-based carbohydrates and lignin with, more recently, the additional criteria that fibers incorporated into foods as additives should demonstrate functional human health outcomes to receive a fiber classification. Thousands of research studies have been published examining fibers and health outcomes.(1 Develop a database listing studies testing fiber and physiological health outcomes identified by experts at the Ninth Vahouny Conference; (2 Use evidence mapping methodology to summarize this body of literature. This paper summarizes the rationale, methodology, and resulting database. The database will help both scientists and policy-makers to evaluate evidence linking specific fibers with physiological health outcomes, and identify missing information.To build this database, we conducted a systematic literature search for human intervention studies published in English from 1946 to May 2015. Our search strategy included a broad definition of fiber search terms, as well as search terms for nine physiological health outcomes identified at the Ninth Vahouny Fiber Symposium. Abstracts were screened using a priori defined eligibility criteria and a low threshold for inclusion to minimize the likelihood of rejecting articles of interest. Publications then were reviewed in full text, applying additional a priori defined exclusion criteria. The database was built and published on the Systematic Review Data Repository (SRDR™, a web-based, publicly available application.A fiber database was created. This resource will reduce the unnecessary replication of effort in conducting systematic reviews by serving as both a central database archiving PICO (population, intervention, comparator, outcome data on published studies and as a searchable tool through which this data can be extracted and updated.

    This paper describes the rationale, study design and procedures of the National Eye Survey of Trinidad and Tobago (NESTT). The main objective of this survey is to obtain prevalence estimates of vision impairment and blindness for planning and policy development. A population-based, cross-sectional survey was undertaken using random multistage cluster sampling, with probability-proportionate-to-size methods. Eligible participants aged 5 years and older were sampled from the non-institutional population in each of 120 cluster segments. Presenting distance and near visual acuity were screened in their communities. People aged 40 years and older, and selected younger people, were invited for comprehensive clinic assessment. The interview included information on potential risk factors for vision loss, associated costs and quality of life. The examination included measurement of anthropometrics, blood glucose, refraction, ocular biometry, corneal hysteresis, and detailed assessment of the anterior and posterior segments, with photography and optical coherence tomography imaging. Adult participants were invited to donate saliva samples for DNA extraction and storage. The fieldwork was conducted over 13 months in 2013-2014. A representative sample of 10,651 individuals in 3410 households within 120 cluster segments identified 9913 people who were eligible for recruitment. The study methodology was robust and adequate to provide the first population-based estimates of the prevalence and causes of visual impairment and blindness in Trinidad and Tobago. Information was also gathered on risk factors, costs and quality of life associated with vision loss, and on normal ocular parameters for the population aged 40 years and older.

    This report documents assessments that address waste issues and life cycle impacts associated with the vehicle materials and vehicle technologies being developed under the Partnership for a New Generation of Vehicles (PNGV) program. We refer to these vehicles as 3XVs, referring to the PNGV goal that their fuel mileage be three times better than the baseline vehicle. To meet the program's fuel consumption goals, these vehicles substitute lightweight materials for heavier materials such as steel and iron that currently dominate the composition of vehicles, and use engineering and power system changes. Alternative power systems being developed through the PNGV program include batteries for hybrid electric vehicles and fuel cells. With respect to all these developments, it is imperative to learn what effects they will have on the environment before adopting these designs and technologies on a large-scale basis.

    2010-07-01

    The decarbonization of transport is a key element in both energy and environmental European policies as well as one of the levers that will help us achieve the goals of improving energy efficiency, reducing CO{sub 2} emissions and energy dependence. The use of electricity compared to other low-carbon fuels such as bio fuels and hydrogen has the advantage of its existing infrastructure (power generation plants, transmission and distribution networks), being only necessary to developed recharging infrastructures. We emphasize the role of electricity networks and their evolution, which will enable to manage demand and maximise the potential of renewable energies. The idea of an electric vehicle is not a recent one but dates back to the beginning of the last century, when first units appeared. Unfortunately, technological barriers were too high at the time to let them succeed. Namely those barriers limited the range of the electric vehicle due to problems with battery recharges. Nowadays, those difficulties have almost been solved and we can state that institutional support and coordination among all actors involved have made the electric vehicle a plausible reality. While the technological improvements needed for the electric vehicle to become cost competitive are carried out, the plug-in hybrid vehicle represents the intermediate step to reach a total decarbonization of transport. Endesa is committed to this revolution in transport mobility and believes that now is the right time to focus our efforts on it. Our goal is to contribute to a more balanced and sustainable world in the near future. (Author)

  6. VEHICLE OWNERSHIP AND TRIP GENERATION MODELLING

    Directory of Open Access Journals (Sweden)

    Pattarathep SILLAPARCHARN

    2007-01-01

    Full Text Available This paper aims to address some important issues of a rapid growth in vehicle ownership, how different types of vehicles interact and how these growths affect a number of trip generations, especially in a country undergoing fast economic development, such as Thailand. The forecasts of such growth are important for strategic transport decision-making, travel demand forecasts and other policy issues at both regional and national levels. For these reasons, a series of vehicle ownership models, which include: (1 car, (2 motorcycle, (3 truck and heavy goods vehicle and (4 bus and coach models, are proposed together with a trip generation model. These models are built upon the limited aggregate data, both time series and cross sectional and disaggregated spatially by province, using non-log-linear weighted least squares regression for motor vehicle ownership models and exponential modelling for a trip generation model. The inputs required are basically forecasted gross provincial products per capita and population level. All proposed models have good statistical properties, i.e. all statistically significant coefficients and high adjusted R squared value and very good fits which are within 12% of observed values during the base years. The car ownership model also gives reasonable car ownership elasticities with respect to income and a sensible saturation level when compared with other studies. The forecast for a case of increasing income shows that the car and truck ownership level will increase together with the trip generation level. However, as people own more cars, the motorcycle and bus ownership levels will decrease as there might be a switch to car ownership.

    1974-01-01

    A summary of the constraints and requirements on the Earth Observatory Satellite (EOS-A) orbit and launch vehicle analysis is presented. The propulsion system (hydrazine) and the launch vehicle (Delta 2910) selected for EOS-A are examined. The rationale for the selection of the recommended orbital altitude of 418 nautical miles is explained. The original analysis was based on the EOS-A mission with the Thematic Mapper and the High Resolution Pointable Imager. The impact of the revised mission model is analyzed to show how the new mission model affects the previously defined propulsion system, launch vehicle, and orbit. A table is provided to show all aspects of the EOS multiple mission concepts. The subjects considered include the following: (1) mission orbit analysis, (2) spacecraft parametric performance analysis, (3) launch system performance analysis, and (4) orbits/launch vehicle selection.

  8. Supplement use in sport: is there a potentially dangerous incongruence between rationale and practice?

    Naughton Declan P

    2007-05-01

    Full Text Available Abstract Background Supplement use by athletes is complex and research supports the alarming notion of misinformed decisions regarding supplements. Hypothesis A frequent divergence between the type of supplements chosen by athletes and the rationale dictating the supplement use is hypothesized. Thus, a potentially dangerous incongruence may exist between rationale and practice. Testing the hypothesis In the continued absence of reliable data on supplement use, an alternative approach of studying the reasons underlying supplement use in athletes is proposed to determine whether there is an incongruence between rationale and practice. Existing data from large scale national surveys can be used to investigate this incongruence. Implications of the hypothesis In this report, analyses of distinctive patterns between the use and rationale for use of supplements among athletes are recommended to explore this potentially dangerous phenomenon.

  12. Non-exhaust PM emissions from electric vehicles

    Science.gov (United States)

    Timmers, Victor R. J. H.; Achten, Peter A. J.

    2016-06-01

    Particulate matter (PM) exposure has been linked to adverse health effects by numerous studies. Therefore, governments have been heavily incentivising the market to switch to electric passenger cars in order to reduce air pollution. However, this literature review suggests that electric vehicles may not reduce levels of PM as much as expected, because of their relatively high weight. By analysing the existing literature on non-exhaust emissions of different vehicle categories, this review found that there is a positive relationship between weight and non-exhaust PM emission factors. In addition, electric vehicles (EVs) were found to be 24% heavier than equivalent internal combustion engine vehicles (ICEVs). As a result, total PM10 emissions from EVs were found to be equal to those of modern ICEVs. PM2.5 emissions were only 1-3% lower for EVs compared to modern ICEVs. Therefore, it could be concluded that the increased popularity of electric vehicles will likely not have a great effect on PM levels. Non-exhaust emissions already account for over 90% of PM10 and 85% of PM2.5 emissions from traffic. These proportions will continue to increase as exhaust standards improve and average vehicle weight increases. Future policy should consequently focus on setting standards for non-exhaust emissions and encouraging weight reduction of all vehicles to significantly reduce PM emissions from traffic.

    1997-01-01

    Hybrid electric power trains may revolutionize today's ground passenger vehicles by significantly improving fuel economy and decreasing emissions. The NASA Lewis Research Center is working with industry, universities, and Government to develop and demonstrate a hybrid electric vehicle. Our partners include Bowling Green State University, the Cleveland Regional Transit Authority, Lincoln Electric Motor Division, the State of Ohio's Department of Development, and Teledyne Ryan Aeronautical. The vehicle will be a heavy class urban transit bus offering double the fuel economy of today's buses and emissions that are reduced to 1/10th of the Environmental Protection Agency's standards. At the heart of the vehicle's drive train is a natural-gas-fueled engine. Initially, a small automotive engine will be tested as a baseline. This will be followed by the introduction of an advanced gas turbine developed from an aircraft jet engine. The engine turns a high-speed generator, producing electricity. Power from both the generator and an onboard energy storage system is then provided to a variable-speed electric motor attached to the rear drive axle. An intelligent power-control system determines the most efficient operation of the engine and energy storage system.

    2015-01-01

    The liftoff phase induces acoustic loading over a broad frequency range for a launch vehicle. These external acoustic environments are then used in the prediction of internal vibration responses of the vehicle and components which result in the qualification levels. Thus, predicting these liftoff acoustic (LOA) environments is critical to the design requirements of any launch vehicle. If there is a significant amount of uncertainty in the predictions or if acoustic mitigation options must be implemented, a subscale acoustic test is a feasible pre-launch test option to verify the LOA environments. The NASA Space Launch System (SLS) program initiated the Scale Model Acoustic Test (SMAT) to verify the predicted SLS LOA environments and to determine the acoustic reduction with an above deck water sound suppression system. The SMAT was conducted at Marshall Space Flight Center and the test article included a 5% scale SLS vehicle model, tower and Mobile Launcher. Acoustic and pressure data were measured by approximately 250 instruments. The SMAT liftoff acoustic results are presented, findings are discussed and a comparison is shown to the Ares I Scale Model Acoustic Test (ASMAT) results.

  6. Sizing of scramjet vehicles

    Ingenito, A.; Gulli, S.; Bruno, C.

    2011-10-01

    The current European project LAPCAT II has the ambitious goal to define a conceptual vehicle capable of achieving the antipodal range Brussels-Sydney (~18,000 km) in about 2 h at Mach number Ma = 8. At this high speed, the requirement of high lift to drag (L/D) ratio is critical to high performance, because of high skin friction and wave drag: in fact, as the Mach number increases, the L/D ratio decreases. The design of the vehicle architecture (shape and propulsion system) is, as a consequence, crucial to achieve a reasonably high L/D. In this work, critical parameters for the preliminary sizing of a hypersonic airbreathing airliner have been identified. In particular, for a given Technology Readiness Level (TRL) and mission requirements, a solution space of possible vehicle architectures at cruise have been obtained. In this work, the Gross Weight at Take-Off (TOGW) was deliberately discarded as a constraint, based on previous studies by Czysz and Vanderkerkhove [1]. Typically, limiting from the beginning, the TOGW leads to a vicious spiral where weight and propulsion system requirements keep growing, eventually denying convergence. In designing passenger airliners, in fact, it is the payload that is assumed fixed from the start, not the total weight. In order to screen the solutions found, requirements for taking-off (TO) and landing as well as the trajectory have been accounted for. A consistent solution has finally been obtained by imposing typical airliner constraints: emergency take-off and landing. These constraints enable singling out a realistic design from the broad family of vehicles capable of performing the given mission. This vehicle has been obtained by integrating not only aerodynamics, trajectory, and airliner constraints, but also by integrating the propulsion system, the trimming devices and by doing some adjustments to the conceptual vehicle shape (i. e., spatular nose). Thus, the final vehicle is the result of many iterations in the design

    2009-12-15

    Transportation within the EU, as in most of the industrialized world, shows an increasing trend in CO{sub 2} emissions. This calls for measures to decrease the amount of transportation but also to increase the efficiency in the vehicle fleet. To achieve this, numerous policy measures are available, all of which targets the agents in the economy in various ways. Policy makers thus face a highly complex task. The present paper aims at providing a simple and transparent analytical model that illustrates how different policy measures address different parts of an interlinked system, which determines the composition of the future car fleet. Apart from being simple, and thereby providing an intuitive framework, the model provides important lessons for policy design, e.g., through highlighting the difference between initial responses to policies and the outcome in equilibrium both in the short and the long run.

    In India, there is growing interest among policymakers, planners, and regulators for aggressive electrification of passenger vehicles. For example, Piyush Goyal, the Minister of State for India’s Ministry of Coal, Power, New and Renewable Energy, announced an aspirational goal of converting all vehicle sales in India to battery electric vehicles (BEVs) by 2030 (Economic Times, 2016). In 2012, India has already announced the National Mission on Electric Mobility (NMEM) sets a countrywide goal of deploying 6 to 7 million hybrid and electric vehicles (EVs) by 2020 (DHI, 2012). A major policy motivation for transport electrification is to reduce India’s oil import dependency. The objective of this paper is to assess the effect of full electrification of vehicle sales in India by 2030 on the key stakeholders such as BEV owners, electric utilities, and the government. Specifically, we attempt to answer the following questions: (a) How does the total vehicle ownership cost of BEVs compare with the conventional vehicles? (b) What is the additional load due BEV charging? (c) What is the impact on the power sector investments, costs, and utility revenue? (d) How can smart BEV charging help renewable energy grid integration? (e) What is the impact on the crude oil imports? (f) What is the impact on the greenhouse gas (GHG) emissions?

    Background Effective medications to treat cocaine dependence have not been identified. Recent pharmacotherapy trials demonstrate the potential efficacy of buprenorphine (BUP) (alone or with naltrexone) for reducing cocaine use. The National Institute on Drug Abuse Clinical Trials Network (CTN) launched the Cocaine Use Reduction with Buprenorphine (CURB) investigation to examine the safety and efficacy of sublingual BUP (as Suboxone®) in the presence of extended-release injectable naltrexone (XR-NTX, as Vivitrol®) for the treatment of cocaine dependence. This paper describes the design and rationale for this study. Methods This multi-site, double-blind, placebo-controlled study will randomize 300 participants across 11 sites. Participants must meet the DSM-IV criteria for cocaine dependence and past or current opioid dependence or abuse. Participants are inducted onto XR-NTX after self-reporting at least 7 days of abstinence from opioids and tolerating a naloxone challenge followed by oral naltrexone and are then randomly assigned to one of three medication conditions (4 mg BUP, 16 mg BUP, or placebo) for 8 weeks. Participants receive a second injection of XR-NTX 4 weeks after the initial injection, and follow-up visits are scheduled at 1 and 3 months post-treatment. Participants receive weekly cognitive behavioral therapy (CBT). Recruitment commenced in September, 2011. Enrollment, active medication, and follow-up phases are ongoing, and recruitment is exceeding targeted enrollment rates. Conclusions This research using 2 medications will demonstrate whether BUP, administered in the presence of XR-NTX, reduces cocaine use in adults with cocaine dependence and opioid use disorders and will demonstrate if XR-NTX prevents development of physiologic dependence on BUP.

    Retinal photocoagulation and nondamaging laser therapy are used for treatment of macular disorders, without understanding of the response mechanism and with no rationale for dosimetry. To establish a proper titration algorithm, we measured the range of tissue response and damage threshold. We then evaluated safety and efficacy of nondamaging retinal therapy (NRT) based on this algorithm for chronic central serous chorioretinopathy (CSCR) and macular telangiectasia (MacTel). Retinal response to laser treatment below damage threshold was assessed in pigmented rabbits by expression of the heat shock protein HSP70 and glial fibrillary acidic protein (GFAP). Energy was adjusted relative to visible titration using the Endpoint Management (EpM) algorithm. In clinical studies, 21 eyes with CSCR and 10 eyes with MacTel were treated at 30% EpM energy with high spot density (0.25-diameter spacing). Visual acuity, retinal and choroidal thickness, and subretinal fluid were monitored for 1 year. At 25% EpM energy and higher, HSP70 was expressed acutely in RPE, and GFAP upregulation in Müller cells was observed at 1 month. Damage appeared starting at 40% setting. Subretinal fluid resolved completely in 81% and partially in 19% of the CSCR patients, and visual acuity improved by 12 ± 3 letters. Lacunae in the majority of MacTel patients decreased while preserving the retinal thickness, and vision improved by 10 letters. Heat shock protein expression in response to hyperthermia helps define the therapeutic window for NRT. Lack of tissue damage enables high-density treatment to boost clinical efficacy, therapy in the fovea, and retreatments to manage chronic diseases.

    The authors conducted a review of the history and empirical basis of genomewide association studies (GWAS), the rationale for GWAS of psychiatric disorders, results to date, limitations, and plans for GWAS meta-analyses. A literature review was carried out, power and other issues discussed, and planned studies assessed. Most of the genomic DNA sequence differences between any two people are common (frequency >5%) single nucleotide polymorphisms (SNPs). Because of localized patterns of correlation (linkage disequilibrium), 500,000 to 1,000,000 of these SNPs can test the hypothesis that one or more common variants explain part of the genetic risk for a disease. GWAS technologies can also detect some of the copy number variants (deletions and duplications) in the genome. Systematic study of rare variants will require large-scale resequencing analyses. GWAS methods have detected a remarkable number of robust genetic associations for dozens of common diseases and traits, leading to new pathophysiological hypotheses, although only small proportions of genetic variance have been explained thus far and therapeutic applications will require substantial further effort. Study design issues, power, and limitations are discussed. For psychiatric disorders, there are initial significant findings for common SNPs and for rare copy number variants, and many other studies are in progress. GWAS of large samples have detected associations of common SNPs and of rare copy number variants with psychiatric disorders. More findings are likely, since larger GWAS samples detect larger numbers of common susceptibility variants, with smaller effects. The Psychiatric GWAS Consortium is conducting GWAS meta-analyses for schizophrenia, bipolar disorder, major depressive disorder, autism, and attention deficit hyperactivity disorder. Based on results for other diseases, larger samples will be required. The contribution of GWAS will depend on the true genetic architecture of each disorder.

    Lehr, William H.; Pupillo, Lorenzo Maria

    The Internet is now widely regarded as essential infrastructure for our global economy and society. It is in our homes and businesses. We use it to communicate and socialize, for research, and as a platform for E-commerce. In the late 1990s, much was predicted about what the Internet has become at present; but now, we have actual experience living with the Internet as a critical component of our everyday lives. Although the Internet has already had profound effects, there is much we have yet to realize. The present volume represents a third installment in a collaborative effort to highlight the all-encompassing, multidisciplinary implications of the Internet for public policy. The first installment was conceived in 1998, when we initiated plans to organize an international conference among academic, industry, and government officials to discuss the growing policy agenda posed by the Internet. The conference was hosted by the European Commission in Brussels in 1999 and brought together a diverse mix of perspectives on what the pressing policy issues would be confronting the Internet. All of the concerns identified remain with us today, including how to address the Digital Divide, how to modify intellectual property laws to accommodate the new realities of the Internet, what to do about Internet governance and name-space management, and how to evolve broadcast and telecommunications regulatory frameworks for a converged world.

    Participation in regular prolonged physical exercise is associated with specific adaptation in cardiac structure and function which could predispose to sudden cardiac death and has been recorded in celebrated cases and with an increasing frequency in recent time especially in Nigerian footballers. There is no policy or strategy in place for preventing recurrence To review the current literature on sudden death in athletes generally, identify current strategies that have been found useful and recommend measures to prevent or reduce prevalence in Nigerian sportsmen. Internet search on the subject using Google and Medline web search engine. The search words were sudden death, athletes, Africans and sports screening. Sudden death in young athletes is rare occurring in in n 100,000 to 1 in 280,000 persons per year and hypertrophic cardiomyopathy is the commonest cause and blacks are more affected than caucasians. Screening guidelines are available in some countries and mandatory pre participatory screening has reduced the incidence of sudden death in athletes in these countries. In Nigeria there is no legislation or policy on routine screening in sportsmen or measures to prevent or reduce incident of sudden death in athletes. There has been increased report of sudden death in Nigerian footballers in recent years and the investigations into these deaths are shrouded in secrecy. There is no policy for routine screening of sports participants in Nigeria, there is urgent need to develop a policy to ensure appropriate pre participation screening for all sportsmen and women each year or at the beginning of each sports season.

  8. Electric vehicle drive systems

    Appleyard, M.

    1992-01-01

    New legislation in the State of California requires that 2% of vehicles sold there from 1998 will be 'zero-emitting'. This provides a unique market opportunity for developers of electric vehicles but substantial improvements in the technology are probably required if it is to be successfully exploited. There are around a dozen types of battery that are potentially relevant to road vehicles but, at the present, lead/acid and sodium—sulphur come closest to combining acceptable performance, life and cost. To develop an efficient, lightweight electric motor system requires up-to-date techniques of magnetics design, and the latest power-electronic and microprocessor control methods. Brushless machines, coupled with solid-state inverters, offer the most economical solution for mass production, even though their development costs are higher than for direct-current commutator machines. Fitted to a small car, even the highest energy-density batteries will only provide around 200 km average range before recharging. Therefore, some form of supplementary on-board power generation will probably be needed to secure widespread acceptance by the driving public. Engine-driven generators of quite low power can achieve useful increases in urban range but will fail to qualify as 'zero-emitting'. On the other hand, if the same function could be economically performed by a small fuel-cell using hydrogen derived from a methanol reformer, then most of the flexibility provided by conventional vehicles would be retained. The market prospects for electric cars would then be greatly enhanced and their dependence on very advanced battery technology would be reduced.

    Hydrogen is an especially attractive transportation fuel. It is the least polluting fuel available, and can be produced anywhere there is water and a clean source of electricity. A fuel cycle in which hydrogen is produced by solar-electrolysis of water, or by gasification of renewably grown biomass, and then used in a fuel-cell powered electric-motor vehicle (FCEV), would produce little or no local, regional, or global pollution. Hydrogen FCEVs would combine the best features of bat...

  16. Payload vehicle aerodynamic reentry analysis

    Science.gov (United States)

    Tong, Donald

    An approach for analyzing the dynamic behavior of a cone-cylinder payload vehicle during reentry to insure proper deployment of the parachute system and recovery of the payload is presented. This analysis includes the study of an aerodynamic device that is useful in extending vehicle axial rotation through the maximum dynamic pressure region. Attention is given to vehicle configuration and reentry trajectory, the derivation of pitch static aerodynamics, the derivation of the pitch damping coefficient, pitching moment modeling, aerodynamic roll device modeling, and payload vehicle reentry dynamics. It is shown that the vehicle dynamics at parachute deployment are well within the design limit of the recovery system, thus ensuring successful payload recovery.

    Garcia, Richard D.; Sturgeon, Purser; Brown, Mike

    2012-06-01

    The last decade has seen a significant increase in intelligent safety devices on private automobiles. These devices have both increased and augmented the situational awareness of the driver and in some cases provided automated vehicle responses. To date almost all intelligent safety devices have relied on data directly perceived by the vehicle. This constraint has a direct impact on the types of solutions available to the vehicle. In an effort to improve the safety options available to a vehicle, numerous research laboratories and government agencies are investing time and resources into connecting vehicles to each other and to infrastructure-based devices. This work details several efforts in both the commercial vehicle and the private auto industries to increase vehicle safety and driver situational awareness through vehicle-to-vehicle and vehicle-to-infrastructure communication. It will specifically discuss intelligent behaviors being designed to automatically disable non-compliant vehicles, warn tractor trailer vehicles of unsafe lane maneuvers such as lane changes, passing, and merging, and alert drivers to non-line-of-sight emergencies.

    1994-02-01

    Due to the recently enacted California regulations requiring zero emission vehicles be sold in the market place by 1998, electric vehicle research and development (R&D) is accelerating. Much of the R&D work is focusing on the Achilles' heel of electric vehicles -- advanced batteries. This report provides an assessment of the R&D work currently underway in advanced batteries and electric vehicles in the following countries: Denmark, France, Germany, Italy, Japan, Russia, and the United Kingdom. Although the US can be considered one of the leading countries in terms of advanced battery and electric vehicle R&D work, it lags other countries, particularly France, in producing and promoting electric vehicles. The US is focusing strictly on regulations to promote electric vehicle usage while other countries are using a wide variety of policy instruments (regulations, educational outreach programs, tax breaks and subsidies) to encourage the use of electric vehicles. The US should consider implementing additional policy instruments to ensure a domestic market exists for electric vehicles. The domestic is the largest and most important market for the US auto industry.

    A modular robotic vehicle includes a chassis, driver input devices, an energy storage system (ESS), a power electronics module (PEM), modular electronic assemblies (eModules) connected to the ESS via the PEM, one or more master controllers, and various embedded controllers. Each eModule includes a drive wheel containing a propulsion-braking module, and a housing containing propulsion and braking control assemblies with respective embedded propulsion and brake controllers, and a mounting bracket covering a steering control assembly with embedded steering controllers. The master controller, which is in communication with each eModule and with the driver input devices, communicates with and independently controls each eModule, by-wire, via the embedded controllers to establish a desired operating mode. Modes may include a two-wheel, four-wheel, diamond, and omni-directional steering modes as well as a park mode. A bumper may enable docking with another vehicle, with shared control over the eModules of the vehicles.

    Full Text Available The Brazilian automotive industry accounted for 18% of Gross Domestic Product Industrial in 2012, moreover, this segment has strong linkages with other activities in the economy. After declining sales of vehicles in order to encourage growth in the sector, the government adopted a countercyclical policy to reduce TAX (IPI. This policy aimed at increasing the sales. In this sense, the objective of this study was to determine if measure was effective for the recovery of vehicle sales. The analysis follows a cointegration model. Some simulations indicate the the countercyclical policy accounted for 31.07% of vehicle sales from May to December 2012, suggesting the policy was effective and leveraged the automobile industry.

    Household Vehicles Energy Consumption 1994 reports on the results of the 1994 Residential Transportation Energy Consumption Survey (RTECS). The RTECS is a national sample survey that has been conducted every 3 years since 1985. For the 1994 survey, more than 3,000 households that own or use some 6,000 vehicles provided information to describe vehicle stock, vehicle-miles traveled, energy end-use consumption, and energy expenditures for personal vehicles. The survey results represent the characteristics of the 84.9 million households that used or had access to vehicles in 1994 nationwide. (An additional 12 million households neither owned or had access to vehicles during the survey year.) To be included in then RTECS survey, vehicles must be either owned or used by household members on a regular basis for personal transportation, or owned by a company rather than a household, but kept at home, regularly available for the use of household members. Most vehicles included in the RTECS are classified as {open_quotes}light-duty vehicles{close_quotes} (weighing less than 8,500 pounds). However, the RTECS also includes a very small number of {open_quotes}other{close_quotes} vehicles, such as motor homes and larger trucks that are available for personal use.

    Beijing, the capital of China, has experienced rapid motorization since 1990; a trend that is likely to continue. The growth in vehicles and the corresponding emissions create challenges to improving the urban air quality. In an effort to reduce the impact of vehicle emissions on urban air quality, Beijing has adopted a number of vehicle emission control strategies and policies since the mid 1990 s. These are classified into seven categories: (1) emission control on new vehicles; (2) emission control on in-use vehicles; (3) fuel quality improvements; (4) alternative-fuel and advanced vehicles; (5) economic policies; (6) public transport; and (7) temporal traffic control measures. Many have proven to be successful, such as the Euro emission standards, unleaded gasoline and low sulfur fuel, temporal traffic control measures during the Beijing Olympic Games, etc. Some, however, have been failures, such as the gasoline-to-LPG taxi retrofit program. Thanks to the emission standards for new vehicles as well as other controls, the fleet-average emission rates of CO, HC, NO(X), and PM(10) by each major vehicle category are decreasing over time. For example, gasoline cars decreased fleet-average emission factors by 12.5% for CO, 10.0% for HC, 5.8% for NO(X), and 13.0% for PM(10) annually since 1995, and such a trend is likely to continue. Total emissions for Beijing's vehicle fleet increased from 1995 to 1998. However, they show a clear and steady decrease between 1999 and 2009. In 2009, total emissions of CO, HC, NO(X), and PM(10) were 845,000 t, 121,000 t, 84,000 t, and 3700 t, respectively; with reductions of 47%, 49%, 47%, and 42%, relative to 1998. Beijing has been considered a pioneer in controlling vehicle emissions within China, similar to the role of California to the U.S. The continued rapid growth of vehicles, however, is challenging Beijing's policy-makers.

  9. Rationale for an early detection program for bladder cancer

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Introduction : A total of 356,557 new cases were diagnosed annually worldwide in 2009, it was estimated that 52,810 new patients were to be diagnosed with bladder cancer and there were 10,180 projected deaths from the disease in the USA. Despite being the fourth commonest cancer in men, we do not have an early detection/screening program for bladder cancer. The review was aimed at looking at the evidence for the rationale for an early detection program for bladder cancer. Materials and Methods : A detailed search on bladder cancer epidemiology, diagnosis, pathology, tumor markers, treatment outcomes, screening, morbidity and mortality of bladder cancer was carried out on Pubmed central/Medline. Original articles, review articles, monograms, book chapters on bladder cancer, text books on urological oncology, oncology and urology were reviewed. The latest information for new articles before publication was last accessed in June 2010. Discussion and Conclusions : Bladder cancer is the fourth commonest cancer in men, the annual death rate from this disease is significant and every year there is an increase in its incidence globally. The prognosis of bladder cancer is stage and grade dependent; the lower the stage (T2 or less the better is the survival. Delay in the diagnosis and treatment does alter the overall outcome. Therefore, there is a clear need for early detection of bladder cancer and screening program. Although we do not have an ideal marker for bladder cancer, it is time we maximize the potential of markers such as UroVysion, NMP22 along with cytology to start such a program. May be as a first step the early detection and screening program could be started in high-risk population. It is not worth waiting till we find the best marker as it would be unfair to our patients. The fear of unnecessary tests and treatment in bladder cancer after its detection in screening program is without any substance. The cost-effectiveness of such a program

    A new vehicle following controller is proposed for autonomous intelligent vehicles. The proposed vehicle following controller not only provides smooth transient maneuvers for unavoidable nonzero initial conditions but also guarantees the asymptotic platoon stability without the availability of feedforward information. Furthermore, the achieved asymptotic platoon stability is shown to be robust to sensor delays and an upper bound for the allowable sensor delays is also provided in this paper.

  17. Incentives for environmentally friendly vehicles. A report from the Environment and Health Protection Administration in Stockholm

    Energy Technology Data Exchange (ETDEWEB)

    Henriksson, Cecilia; Paedam, S. [Inregia AB, Stockholm (Sweden)

    1999-11-01

    This report deals with incentives for environmentally friendly vehicles. The report includes a description of the current status of these vehicles in Sweden, Stockholm County Council, and the City of Stockholm. A forecast of possible development of zero and low emission vehicles is carried out. The major obstacles which currently hinder a market for these vehicles are noted. In order to determine market readiness and factors which affect these firms' purchase of vehicles, interviews were carried out with private firms. This analysis indicates that institutional barriers in Sweden hinder zero and low emission vehicles, with laws and tax policies which offer conflicting signals. To follow international developments, these obstacles must be reduced. Therefore, it is important that Stockholm works to create a positive climate for environmentally friendly vehicles. This means that it is important that the policies recommended in this report are implemented with adequate intensity. Because knowledge about zero and low emission vehicles is limited, there is a need to produce factual information. Information can be spread to a larger group, but it is more cost effective to reach a group which is most likely to accept environmentally friendly vehicles. This could include companies with environmental profiles, or those who drive and use company cars. To increase the effectiveness of this information campaign, we suggest that the City also maintain a demonstration fleet with loaner cars for companies who wish to test these vehicles in daily operation before deciding whether or not to purchase them. The incentive package recommended for Stockholm includes offering parking rebates to various groups who park in the city centre; residents , commercial vehicles, and temporary visitors. For equity reasons, all groups should in practice be offered the rebate. To increase the positive effect of the incentive, environmentally friendly vehicles should also be allowed to drive in

    2011-06-01

    This paper addresses the research question "Are more stringent exhaust emissions standards, as applied to light vehicle type approval, resulting in reduced vehicle pollution in an urban area?" The exhaust emissions of a sample of over fifty thousand road vehicles operating in London were measured using roadside remote sensing absorption spectroscopy techniques (infrared and ultraviolet), combined with Automatic Number Plate Recognition for vehicle identification. Levels of carbon monoxide (CO), hydrocarbons (HC), nitric oxide (NO), and smoke (particulate) exhaust emissions are reported by vehicle class, fuel type, and Euro emissions standard. Emissions from petrol cars of each pollutant were all observed to display a statistically significant reduction with the introduction of each successive Euro emissions standard from Euro 1 onwards. However, Euro 2 diesel cars were observed to emit statistically higher rates of NO than either Euro 1 or Euro 3 standard diesel cars. The study also confirms the continuing 'dieselisation' of the UK passenger car fleet. Mean NO emissions from Euro 4 diesel cars were found to be 6 times higher than Euro 4 petrol cars, highlighting the need to develop a sound understanding of the current and future 'in-use' emissions characteristics of diesel vehicles, and their influence on local air quality. Smoke emissions from TXII London taxis (black cabs) were found to be statistically higher than either earlier TX1 or later TX4 model variants, with possible implications for local air quality policy interventions such as maximum age limits for taxis.

  1. Motor vehicle drivers' injuries in train-motor vehicle crashes.

    Science.gov (United States)

    Zhao, Shanshan; Khattak, Aemal

    2015-01-01

    The objectives of this research were to: (1) identify a more suitable model for modeling injury severity of motor vehicle drivers involved in train-motor vehicle crashes at highway-rail grade crossings from among three commonly used injury severity models and (2) to investigate factors associated with injury severity levels of motor vehicle drivers involved in train-motor vehicle crashes at such crossings. The 2009-2013 highway-rail grade crossing crash data and the national highway-rail crossing inventory data were combined to produce the analysis dataset. Four-year (2009-2012) data were used for model estimation while 2013 data were used for model validation. The three injury severity levels-fatal, injury and no injury-were based on the reported intensity of motor-vehicle drivers' injuries at highway-rail grade crossings. The three injury severity models evaluated were: ordered probit, multinomial logit and random parameter logit. A comparison of the three models based on different criteria showed that the random parameter logit model and multinomial logit model were more suitable for injury severity analysis of motor vehicle drivers involved in crashes at highway-rail grade crossings. Some of the factors that increased the likelihood of more severe crashes included higher train and vehicle speeds, freight trains, older drivers, and female drivers. Where feasible, reducing train and motor vehicle speeds and nighttime lighting may help reduce injury severities of motor vehicle drivers. Copyright © 2014 Elsevier Ltd. All rights reserved.

  2. Free to Learn: The Rationale for Legalizing Homeschooling in Albania

    Directory of Open Access Journals (Sweden)

    Timothy Paul Hagen

    2011-12-01

    Full Text Available In the years following the collapse of communism in 1991, Albania allowed greater freedom in educational choice by abolishing the government monopoly on education and allowing private schools to operate. However, it is only now, two decades after the fall of communism, that Albania is moving towards officially recognizing the most natural and fundamental option for educating its citizens – allowing parents to educate their children at home. By looking at homeschooling from the perspectives of student achievement, individual freedom, and natural rights, this paper will show that it is good and proper for Albania – and all countries worldwide – to legally recognize the natural right of parents to homeschool their children. While homeschooling is the best option for some children, it may not be the best for all children. Homeschooling should be one option alongside public schools, private schools, private tutoring, and distance-learning programs. While this article focuses on homeschooling in Albania, relying on research from North America, it contributes to the wider discussion of homeschooling policy in Europe, where policies range from homeschooling being largely illegal in nations such as Bulgaria and Germany to being freely permitted with minimal regulation in a nation such as the United Kingdom.

    The goal of this project was to install a production-ready, state-of-the-art engine control system on the Mack E7G natural gas engine to improve efficiency and lower exhaust emissions. In addition, the power rating was increased from 300 brake horsepower (bhp) to 325 bhp. The emissions targets were oxides of nitrogen plus nonmethane hydrocarbons of less than 2.5 g/bhp-hr and particulate matter of less than 0.05 g/bhp-hr on 99% methane. Vehicle durability and field testing were also conducted. Further development of this engine should include efficiency improvements and oxides of nitrogen reductions.

    In 2009, the annual car production in China was 13.8 million cars, a year-on-year increase of more than 48% (Sun 2010: 3). In 2010, automobile production reached 18,264,700 units, an increase of 32.4% compared with 2009. China's share of the global market for car sales amounts to 20%, up from 13% (Sun 2010: 4). China became the biggest car market in the world in 2010 (China Association of Automobile Manufacturers CAAM 2011). Considering the car ownership per capita, there is still a huge development potential for the Chinese car market. And it is exactly this huge development potential which makes analysts believe that China will become the largest market for electric vehicles in the future. This belief is shared by the Chinese government, and the government has implemented or drafted several different policies and rules to support and speed up the development of electric vehicles. At the highest policy-making level, the Chinese government adopted the development of electric vehicles in its highest priority national plan, the 12{sup th} Five-Year Plan (12 FYP 2011-2015). At the same time, the electric vehicle industry has been selected as one of the seven strategic emerging industries by the National Development and Reform Commission (NDRC). This again has also been manifested in the 12 FYP. The overall goals foresee a rapid development of electrification of cars in China and by 2015 the number of electric cars on Chinese streets should reach 1 million. The following analysis will take a deeper look into the different policies that are behind these developments in order to increase the understanding of the opportunities and challenges that lie ahead. Hence, contributing to an evaluation of the current development in this field is one of the major goals of this working paper. As in all other countries, there is no single policy dedicated to electric mobility in China today. Yet there are many different policies from different ministries and agencies with

  9. Energy management and vehicle synthesis

    Science.gov (United States)

    Czysz, P.; Murthy, S. N. B.

    The major drivers in the development of launch vehicles for the twenty-first century are reduction in cost of vehicles and operations, continuous reusability, mission abort capability with vehicle recovery, and readiness. One approach to the design of such vehicles is to emphasize energy management and propulsion as being the principal means of improvements given the available industrial capability and the required freedom in selecting configuration concept geometries. A methodology has been developed for the rational synthesis of vehicles based on the setting up and utilization of available data and projections, and a reference vehicle. The application of the methodology is illustrated for a single stage to orbit (SSTO) with various limits for the use of airbreathing propulsion.

    Full Text Available Considering the complexity of lane changing using automated vehicles and the frequency of turning lanes in city settings, this paper aims to generate an accelerated lane-changing trajectory using vehicle-to-vehicle collaboration (V2VC. Based on the characteristics of accelerated lane changing, we used a polynomial method and cooperative strategies for trajectory planning to establish a lane-changing model under different degrees of collaboration with the following vehicle in the target lane by considering vehicle kinematics and comfort requirements. Furthermore, considering the shortcomings of the traditional elliptical vehicle and round vehicle models, we established a rectangular vehicle model with collision boundary conditions by analysing the relationships between the possible collision points and the outline of the vehicle. Then, we established a simulation model for the accelerated lane-changing process in different environments under different degrees of collaboration. The results show that, by using V2VC, we can achieve safe accelerated lane-changing trajectories and simultaneously satisfy the requirements of vehicle kinematics and comfort control.

    In this study participants were provided with either the standard rationale that accompanies the Harvard Group Scale of Hypnotic Susceptibility: A (Shor & Orne, 1962) or a rationale that presented hypnosis as a nondeceptive placebo, consistent with Kirsch's (1994) sociocognitive perspective of hypnosis. The effects of the placebo and standard rationales were highly comparable with respect to hypnotic attitudes; prehypnotic expectancies; objective, subjective, and involuntariness measures of hypnotic responding; as well as a variety of subjective experiences during hypnosis, as measured by the Phenomenology of Consciousness Inventory (Pekala, 1982). Differences among correlations were not evident when measures were compared across groups. However, indices of hypnotic responding were correlated with attitudes in the hypnosis but not the placebo condition, and, generally speaking, the link between subjective experiences during hypnosis and measures of hypnotic responding were more reliable in the placebo than the hypnosis group. Researcher findings are neutral with respect to providing support for altered state versus sociocognitive models of hypnosis.

    Olguin, Abel [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

    2014-07-01

    Hypersonic Glide Vehicles (HGVs) are a type of reentry vehicle that couples the high speed of ballistic missiles with the maneuverability of aircraft. The HGV has been in development since the 1970s, and its technology falls under the category of Conventional Prompt Global Strike (CPGS) weapons. As noted by James M. Acton, a senior associate in the Nuclear Policy Program at the Carnegie Endowment, CPGS is a “missile in search of a mission.” With the introduction of any significant new military capability, a doctrine for use—including specifics regarding how, when and where it would be used, as well as tactics, training and procedures—must be clearly defined and understood by policy makers, military commanders, and planners. In this paper, benefits and limitations of the HGV are presented. Proposed criteria and four scenarios illustrate a possible method for assessing when to use an HGV.

    Our need for wide-band global communications, earth imaging and sensing, atmospheric measurements and military reconnaissance is extensive, but growing dependence on space-based systems raises concerns about vulnerability. Military commanders require space assets that are more accessible and under local control. As a result, a robust and low cost access to space-like capability has become a national priority. Free floating buoyant vehicles in the middle stratosphere can provide the kind of cost effective access to space-like capability needed for a variety of missions. These vehicles are inexpensive, invisible, and easily launched. Developments in payload electronics, atmospheric modeling, and materials combined with improving communications and navigation infrastructure are making balloon-borne concepts more attractive. The important milestone accomplished by this project was the planned test flight over the continental United States. This document is specifically intended to review the technology development and preparations leading up to the test flight. Although the test flight experienced a payload failure just before entering its assent altitude, significant data were gathered. The results of the test flight are presented here. Important factors included in this report include quality assurance testing of the balloon, payload definition and characteristics, systems integration, preflight testing procedures, range operations, data collection, and post-flight analysis. 41 figs., 5 tabs.

    2017-02-01

    Targeted delivery of chemotherapeutic drugs to tumor sites is a major challenge in cancer chemotherapy. Cell-based vectorization of therapeutic agents has great potential for cancer therapy in that it can target and maintain an elevated concentration of therapeutic agents at the tumor site and prevent their spread into healthy tissue. The use of circulating cells such as monocytes/macrophages (Ma) offers several advantages compared to nanoparticles as targeted drug delivery vehicles. Ma can be easily obtained from the patient, loaded in vitro with drugs and reinjected into the blood stream. Ma can selectively cross the partially compromised blood-brain barrier surrounding brain tumors and are known to actively migrate to tumors, drawn by chemotactic factors, including hypoxic regions where conventional chemo and radiation therapy are least effective. The utility of Ma as targeted drug delivery vehicles for photochemical internalization (PCI) of tumors was investigated in this study. In vitro studies were conducted using a mixture of F98 rat glioma cells and rat macrophages loaded with a variety of chemotherapeutic agents including bleomycin and 5-fluorouracil. Preliminary data show that macrophages are resistant to both chemotherapeutics while significant toxicity is observed for F98 cells exposed to both drugs. Co-incubation of F98 cells with loaded Ma results in significant F98 toxicity suggesting that Ma are releasing the drugs and, hence providing the rationale for their use as delivery vectors for cancer therapies such as PCI.

  3. Exponential Stabilization of Underactuated Vehicles

    Energy Technology Data Exchange (ETDEWEB)

    Pettersen, K.Y.

    1996-12-31

    Underactuated vehicles are vehicles with fewer independent control actuators than degrees of freedom to be controlled. Such vehicles may be used in inspection of sub-sea cables, inspection and maintenance of offshore oil drilling platforms, and similar. This doctoral thesis discusses feedback stabilization of underactuated vehicles. The main objective has been to further develop methods from stabilization of nonholonomic systems to arrive at methods that are applicable to underactuated vehicles. A nonlinear model including both dynamics and kinematics is used to describe the vehicles, which may be surface vessels, spacecraft or autonomous underwater vehicles (AUVs). It is shown that for a certain class of underactuated vehicles the stabilization problem is not solvable by linear control theory. A new stability result for a class of homogeneous time-varying systems is derived and shown to be an important tool for developing continuous periodic time-varying feedback laws that stabilize underactuated vehicles without involving cancellation of dynamics. For position and orientation control of a surface vessel without side thruster a new continuous periodic feedback law is proposed that does not cancel any dynamics, and that exponentially stabilizes the origin of the underactuated surface vessel. A further issue considered is the stabilization of the attitude of an AUV. Finally, the thesis discusses stabilization of both position and attitude of an underactuated AUV. 55 refs., 28 figs.

    Writing the theoretical rationale for a study can be a daunting prospect for novice researchers. Nursing's conceptual models provide excellent frameworks for placement of study variables, but moving from the very abstract concepts of the nursing model to the less abstract concepts of the study variables is difficult. Similar to the five-paragraph essay used by writing teachers to assist beginning writers to construct a logical thesis, the authors of this column present guidelines that beginners can follow to construct their theoretical rationale. This guide can be used with any nursing conceptual model but Neuman's model was chosen here as the exemplar.

    In this paper we assume away standard distributional and static-efficiency arguments for public health and instead seek a dynamic efficiency rationale. We study a lifecycle model wherein young agents make health investments to reduce mortality risk. We identify a welfare rationale for public health...... under dynamic efficiency and exogenous mortality even when private and public investments are perfect substitutes. If health investment reduces mortality risk but individuals do not internalize its effect on the life-annuity interest rate, the “Philipson-Becker effect” emerges; when the young are net...... borrowers, this works together with dynamic efficiency to support a role for public health....

    2015-03-01

    In 2011, the Institute of Medicine Early Childhood Prevention Policies Report identified feeding dynamics as an important focus area for childhood obesity prevention and treatment. Feeding dynamics includes two central components: (1) caregiver feeding practices (i.e., determining how, when, where, and what they feed their children) and (2) child eating behaviors (i.e., determining how much and what to eat from what food caregivers have provided). Although there has been great interest in overweight and obesity prevention and treatment in young children, they have not focused comprehensively on feeding dynamics. Interventions on feeding dynamics that reduce caregivers' excessive controlling and restrictive feeding practices and encourage the development of children's self-regulation of energy intake may hold promise for tackling childhood obesity especially in the young child but currently lack an evidence base. This manuscript describes the rationale and design for a randomized controlled trial designed to compare a group of mothers and their 3-to 5-year old children who received an intervention focused primarily on feeding dynamics called the Feeding Dynamic Intervention (FDI) with a Wait-list Control Group (WLC). The primary aim of the study will be to investigate the efficacy of the FDI for decreasing Eating in the Absence of Hunger (EAH) and improving energy compensation (COMPX). The secondary aim will be to examine the effect of the FDI in comparison to the WLC on maternal self-reported feeding practices and child satiety responsiveness. Copyright © 2015 Elsevier Inc.

    2000-07-01

    In urban area, due to their beneficial effect on environment, electric vehicles, hybrid electric vehicles and fuel cell electric vehicles are an important factor for improvement of traffic and more particular for a healthier environment. Moreover, the need for alternative energy source is growing and the price competition of alternatives against oil is becoming more and more realistic. Electric vehicles, hybrid electric vehicles and fuel cell electric vehicles are offering the best possibility for the use of new energy sources, because electricity can result from a transformation with high efficiency of these sources and is always used with the highest possible efficiency in systems with electric drives or components. Some basic considerations about the situation today and in a mid and long-term perspective, are presented together with the infrastructure developments.

  10. Vehicle to grid: electric vehicles as an energy storage solution

    McGee, Rodney; Waite, Nicholas; Wells, Nicole; Kiamilev, Fouad E.; Kempton, Willett M.

    2013-05-01

    With increased focus on intermittent renewable energy sources such as wind turbines and photovoltaics, there comes a rising need for large-scale energy storage. The vehicle to grid (V2G) project seeks to meet this need using electric vehicles, whose high power capacity and existing power electronics make them a promising energy storage solution. This paper will describe a charging system designed by the V2G team that facilitates selective charging and backfeeding by electric vehicles. The system consists of a custom circuit board attached to an embedded linux computer that is installed both in the EVSE (electric vehicle supply equipment) and in the power electronics unit of the vehicle. The boards establish an in-band communication link between the EVSE and the vehicle, giving the vehicle internet connectivity and the ability to make intelligent decisions about when to charge and discharge. This is done while maintaining compliance with existing charging protocols (SAEJ1772, IEC62196) and compatibility with standard "nonintelligent" cars and chargers. Through this system, the vehicles in a test fleet have been able to successfully serve as portable temporary grid storage, which has implications for regulating the electrical grid, providing emergency power, or supplying power to forward military bases.

    2011-01-01

    The rural population in China remains in the majority, and has traditionally played a key role in the development of China. This paper outlines the rhetoric of, and the material changes in the development of rural sports policy in the period since 1949. In effect this represents the largest single programmatic attempt to develop a rural sports policy, and it is one which reflects and contributes to the changing ideology of the state in China. The article explores the historical context of the unfolding of rural sports policy, the rationales provided by state and party leaders and representatives, and the rhetoric employed in supporting such policy direction. The development of policy is described as falling into three periods. From 1949 to 1977 the emphasis was on developing policies to promote labour production and national defence. This was succeeded by a period from 1978 to 2001 in which the major focus was on promoting a culturally positive environment (the construction of a 'spiritual civilization'), while in the period 2002 -08 the concern was with promoting equity and reducing the gap between urban and rural life quality. These developing rationales have sought in a variety of ways to address the major imbalances that exist in Chinese society between urban and rural, Eastern and Western China, and sports policy has thus became a significant tool in China's modernization agenda in the rural context.

  14. Sustainable vehicle fuels - Do they exist?

    Energy Technology Data Exchange (ETDEWEB)

    Boerjesson, Paal; Ericsson, Karin; Di Lucia, Lorenzo; Nilsson, Lars J.; Aahman, Max

    2009-03-15

    Our aim with this report is to discuss vehicle fuels from a wide perspective of sustainability. Biofuels and electricity are analyzed and compared to fossil vehicle fuels. Our goal is to try to point out the circumstances under which vehicle fuels can be reasonably perceived as sustainable, and which systems we should develop and which we should avoid. The all-embracing conclusion of this study is that one can not establish how sustainable fuels will develop in the future without simultaneously taking into consideration both scale and pace of growth. Today's biofuels produced in Sweden are sustainable, given the present production volume, and promote further development of new fuel systems. However, in the case of increased production volumes, exact requirements should be established for the energy- and climate efficiency of the entire fuel chain (from cultivation to tank). High priority should be given to the development of fuel-efficient cars. In this field hybrid electric technology and electric cars will grow in importance. Any long-term strategy for biofuels should include investments in technology for both thermal gasification and biological conversion methods of lignocellulose, since these are complementing as much as competing technologies, both increasing the flexibility as well as decreasing the risk of conflicts. Biogas from waste products has great environmental advantages and the sector can be expanded with only small risks of conflicts. Certification (if correctly formulated) is an important and necessary tool on the way towards more sustainable vehicle fuels and increased production volumes, but certification systems should not be overrated since they can not cover all sustainability aspects. Socio-economic aspects such as working conditions, local rural development etc. must be dealt with through general measures such as national laws, distribution policies, programs and plans, all of which should be supported by international agreements and

    Five consumer vehicle choice models that give projections of future sales shares of light-duty vehicles were compared by running each model using the same inputs, where possible, for two scenarios. The five models compared — LVCFlex, MA3T, LAVE-Trans, ParaChoice, and ADOPT — have been used in support of the Energy Efficiency and Renewable Energy (EERE) Vehicle Technologies Office in analyses of future light-duty vehicle markets under different assumptions about future vehicle technologies and market conditions. The models give projections of sales shares by powertrain technology. Projections made using common, but not identical, inputs showed qualitative agreement, with the exception of ADOPT. ADOPT estimated somewhat lower advanced vehicle shares, mostly composed of hybrid electric vehicles. Other models projected large shares of multiple advanced vehicle powertrains. Projections of models differed in significant ways, including how different technologies penetrated cars and light trucks. Since the models are constructed differently and take different inputs, not all inputs were identical, but were the same or very similar where possible.

    The US DOE sponsors Advanced Vehicle Technology competitions to help educate the public and advance new vehicle technologies. For several years, DOE has provided financial and technical support for the American Tour de Sol. This event showcases electric and hybrid electric vehicles in a road rally across portions of the northeastern United States. The specifications contained in this technical memorandum apply to vehicles that will be entered in the 1997 American Tour de Sol. However, the specifications were prepared to be general enough for use by other teams and individuals interested in developing hybrid electric vehicles. The purpose of the specifications is to ensure that the vehicles developed do not present a safety hazard to the teams that build and drive them or to the judges, sponsors, or public who attend the competitions. The specifications are by no means the definitive sources of information on constructing hybrid electric vehicles - as electric and hybrid vehicles technologies advance, so will the standards and practices for their construction. In some cases, the new standards and practices will make portions of these specifications obsolete.

    This report describes a model for forecasting total US highway travel by all vehicle types, and its implementation in the form of a personal computer program. The model comprises a short-run, econometrically-based module for forecasting through the year 2000, as well as a structural, scenario-based longer term module for forecasting through 2030. The short-term module is driven primarily by economic variables. It includes a detailed vehicle stock model and permits the estimation of fuel use as well as vehicle travel. The longer-tenn module depends on demographic factors to a greater extent, but also on trends in key parameters such as vehicle load factors, and the dematerialization of GNP. Both passenger and freight vehicle movements are accounted for in both modules. The model has been implemented as a compiled program in the Fox-Pro database management system operating in the Windows environment.

  12. Let's call it "aphasia": Rationales for eliminating the term "dysphasia".

    Health professionals, researchers, and policy makers often consider the two terms aphasia and dysphasia to be synonymous. The aim of this article is to argue the merits of the exclusive use of the term aphasia and present a strategy for creating change through institutions such as the WHO-ICD. Our contention is that one term avoids confusion, speech-language pathologists prefer aphasia, scholarly publications indicate a preference for the term aphasia, stroke clinical guidelines indicate a preference for the term aphasia, consumer organizations use the title aphasia in their name and on their websites, and languages other than English use a term similar to aphasia. The use of the term dysphasia in the broader medical community may stem from the two terms being used interchangeably in the ICD10. Aphasia United http://www.shrs.uq.edu.au/aphasiaunited , an international movement for uniting the voice of all stakeholders in aphasia within an international context, will seek to eliminate the use of the term dysphasia.

  13. The polio endgame: rationale behind the change in immunisation.

    2017-04-01

    The decades long effort to eradicate polio is nearing the final stages and oral polio vaccine (OPV) is much to thank for this success. As cases of wild poliovirus continue to dwindle, cases of paralysis associated with OPV itself have become a concern. As type-2 poliovirus (one of three) has been certified eradicated and a large proportion of OPV-related paralysis is caused by the type-2 component of OPV, the World Health Assembly endorsed the phased withdrawal of OPV and the introduction of inactivated polio vaccine (IPV) into routine immunisation schedules as a crucial step in the polio endgame plan. The rapid pace of IPV scale-up and uptake required adequate supply, planning, advocacy, training and operational readiness. Similarly, the synchronised switch from trivalent OPV (all three types) to bivalent OPV (types 1 and 3) involved an unprecedented level of global coordination and country commitment. The important shift in vaccination policy seen through global IPV introduction and OPV withdrawal represents an historical milestone reached in the polio eradication effort.

    The Global EV Outlook represents the collective efforts of two years of primary data gathering and analysis from the Electric Vehicles Initiative (EVI) and IEA. Key takeaways and insights include landscape analysis of electric vehicle (EV) stock/sales and charging station deployment. Existing policy initiatives are delineated and future opportunities highlighted in an ''Opportunity Matrix: Pathways to 2020''. Together EVI countries accounted for more than 90% of world EV stock at the end of 2012. Strong government support in EVI countries on both the supply and demand sides are contributing to rising market penetration. 12 out of 15 EVI countries offer financial support for vehicle purchases, and most employ a mix of financial and non-financial incentives (such as access to restricted highway lanes) to help drive adoption. The Global EV Outlook is a unique and data-rich overview of the state of electric vehicles today, and offers an understanding of the electric vehicle landscape to 2020.

  15. Environmental impacts of electric vehicles in South Africa

    Full Text Available Electric vehicles have been seen by some policymakers as a tool to target reductions in greenhouse gas emissions.1,2 Some researchers have shown that the full environmental impact of electric vehicles depends very much on the cleanliness of the electricity grid.3 In countries such as the USA and China, where coal-fired power plants still play a very important role in electricity generation, the environmental impact of electric vehicles is equivalent to, or even higher than that of cars running on internal combustion engines.4,5 In this study, the environmental impacts of electric vehicles in South Africa were investigated. We found that, as the bulk of South Africa’s electricity is generated from relatively low-quality coal and the advanced exhaust clean up technologies are not implemented in the current coal-fired power plants, the use of electric vehicles in South Africa would not help to cut greenhouse gas emissions now (2010 or in the future (in 2030 using the IRP 2010 Revision 2, policy-adjusted IRP scenario, and actually would lead to higher SOx and NOx emissions.

    This document, issued by the French Ministry of Economy, Finances and Industry, presents national measures fostering alternative vehicles, i.e., electric, natural gas and liquefied oil gas vehicles. Financial supports for studies aiming at optimizing the fleet and choosing the alternative vehicles as well as for purchasing vehicles both by counter procedure and for demonstration programmes are provided. Amount of subsidies, conditions of obtaining and categories of addressees are indicated. The document contains also two relating studies. The first one is titled 'the policy of developing alternative vehicles'. The following four items are addressed: - the present frame favouring the alternative vehicles; - the electric vehicles; - natural gas fuelled vehicles (GNV); - liquefied oil gas fuelled vehicles (GPLc). Although non-polluting the electric vehicles are not tempting because of their rather limited range (80 Km at a battery charging). So far only around 3,000 vehicles were sold. Fifty GNV buses were ordered by RATP and the figure raised at 70 in 1998 and 1999. The GPLc fleet amounts up to 70,000 vehicles and by the end of 2000 it is foreseen to reach the level of 300,000 vehicles. The second study addresses to the issue of natural gas for vehicles. It presents: - its advantages; - its peculiarities; - the action of public authorities; -the current state and trends of GNV vehicles. In a joint effort public authorities and partners of this option are aiming at a fleet of 2500 light service vehicles and 300 bus for urban transport by the end of 1999.

Projections of models differed in significant ways, including how different technologies penetrated cars and light trucks. Since the models are constructed differently and take different inputs, not all inputs were identical, but were the same or very similar where possible. Projections by all models were in close agreement only in the first few years. Although the projections from LVCFlex, MA3T, LAVE-Trans, and ParaChoice were in qualitative agreement, there were significant differences in sales shares given by the different models for individual powertrain types, particularly in later years (2030 and later). For example, projected sales shares of conventional spark-ignition vehicles in 2030 for a given scenario ranged from 35% to 74%. Reasons for such differences are discussed, recognizing that these models were not developed to give quantitatively accurate predictions of future sales shares, but to represent vehicles markets realistically and capture the connections between sales and important influences. Model features were also compared at a high level, and suggestions for further comparison
