Mach, Douglas M.; Blakeslee, Richard J.; Bateman, Monte G.

2009-01-01

We determined total conduction (Wilson) currents and flash rates for 850 overflights of electrified clouds spanning regions including the Southeastern United States, the Western Atlantic Ocean, the Gulf of Mexico, Central America and adjacent oceans, Central Brazil, and the South Pacific. The overflights include storms over land and ocean, with and without lightning, and with positive and negative Wilson currents. We combined these individual storm overflight statistics with global diurnal lightning variation data from the Lightning Imaging Sensor (LIS) and Optical Transient Detector (OTD) to estimate the thunderstorm and electrified shower cloud contributions to the diurnal variation in the global electric circuit. The contributions to the global electric circuit from lightning producing clouds are estimated by taking the mean current per flash derived from the overflight data for land and ocean overflights and combining it with the global lightning rates (for land and ocean) and their diurnal variation derived from the LIS/OTD data. We estimate the contribution of non-lightning producing electrified clouds by assuming several different diurnal variations and total non-electrified storm counts to produce estimates of the total storm currents (lightning and non-lightning producing storms). The storm counts and diurnal variations are constrained so that the resultant total current diurnal variation equals the diurnal variation in the fair weather electric field (+/-15%). These assumptions, combined with the airborne and satellite data, suggest that the total mean current in the global electric circuit ranges from 2.0 to 2.7 kA, which is greater than estimates made by others using other methods.

Long term energy and emission implications of a global shift to electricity-based public rail transportation system

Chaturvedi, Vaibhav; Kim, Son H.

2015-01-01

With high reliance on light-duty vehicles in the present, the future of global transportation system is also geared towards private modes, which has significant energy and emission implications. Public transportation has been argued as an alternative strategy for meeting the rising transportation demands of the growing world, especially the poor, in a sustainable and energy efficient way. The present study analyzes an important yet under-researched question – what are the long-term energy and emission implications of an electric rail based passenger transportation system for meeting both long and short distance passenter transportation needs? We analyze a suite of electric rail share scenarios with and without climate policy. In the reference scenario, the transportation system will evolve towards dominance of fossil based light-duty vehicles. We find that an electric rail policy is more successful than an economy wide climate policy in reducing transport sector energy demand and emissions. Economy wide emissions however can only be reduced through a broader climate policy, the cost of which can be reduced by hundreds of billions of dollars across the century when implemented in combination with the transport sector focused electric rail policy. Moreover, higher share of electric rail enhances energy security for oil importing nations and reduces vehicular congestion and road infrastructure requirement as well. -- Highlights: •Economy wide carbon price policy will have little impact on transportation emissions. •Focused energy and emission mitigation policies required for transportation sector. •Large global shift towards electric rail based public transport is one possible option. •Transport sector focused policy will have marginal impact on total global emissions. •A combined transport sector and economy wide policy can reduce costs significantly

High Resolution Global Electrical Conductivity Variations in the Earth's Mantle

Kelbert, A.; Sun, J.; Egbert, G. D.

2013-12-01

Electrical conductivity of the Earth's mantle is a valuable constraint on the water content and melting processes. In Kelbert et al. (2009), we obtained the first global inverse model of electrical conductivity in the mantle capable of providing constraints on the lateral variations in mantle water content. However, in doing so we had to compromise on the problem complexity by using the historically very primitive ionospheric and magnetospheric source assumptions. In particular, possible model contamination by the auroral current systems had greatly restricted our use of available data. We have now addressed this problem by inverting for the external sources along with the electrical conductivity variations. In this study, we still focus primarily on long period data that are dominated by quasi-zonal source fields. The improved understanding of the ionospheric sources allows us to invert the magnetic fields directly, without a correction for the source and/or the use of transfer functions. It allows us to extend the period range of available data to 1.2 days - 102 days, achieving better sensitivity to the upper mantle and transition zone structures. Finally, once the source effects in the data are accounted for, a much larger subset of observatories may be used in the electrical conductivity inversion. Here, we use full magnetic fields at 207 geomagnetic observatories, which include mid-latitude, equatorial and high latitude data. Observatory hourly means from the years 1958-2010 are employed. The improved quality and spatial distribution of the data set, as well as the high resolution modeling and inversion using degree and order 40 spherical harmonics mapped to a 2x2 degree lateral grid, all contribute to the much improved resolution of our models, representing a conceptual step forward in global electromagnetic sounding. We present a fully three-dimensional, global electrical conductivity model of the Earth's mantle as inferred from ground geomagnetic

Development of the electric utility industry in the 21st Century will be central to the well-being of mankind. Electricity worldwide is still likely to be produced mainly from fossil fuel combustion for the foreseeable future. On a global scale, this energy sector will contribute to growing carbon dioxide (CO 2 ) emissions through most of the next century. A potential for global climate alteration has been identified with accumulation of CO 2 and other greenhouse gases (GHGs) in the Earth's atmosphere. If climate changes, adverse environmental effects are possible, acting on human systems, as well as on managed and natural ecosystems. Projected rates of increase in atmospheric CO 2 levels for the next century have motivated decision makers to consider early strategies for beginning to aggressively manage GHG emissions. The objective of this paper is to review the global issues associated with expected increases in gaseous emissions, particularly carbon dioxide from increased energy use, indicating the nature and significance of the issue. The authors emphasize a methodology integrating information on environmental issues with social and economic factors to develop informed international policies. The paper summarizes the technological choices available worldwide that could minimize the environmental impact of increasing energy use, particularly with respect to enhanced electricity production

Potential for reducing global carbon emissions from electricity production-A bench marking analysis

We present five performance indicators for electricity generation for 129 countries using the 2005 data. These indicators, measured at the national level, are the aggregate CO{sub 2} intensity of electricity production, the efficiencies of coal, oil and gas generation and the share of electricity produced from non-fossil fuels. We conduct a study on the potential for reducing global energy-related CO{sub 2} emissions from electricity production through simple bench marking. This is performed based on the last four performance indicators and the construction of a cumulative curve for each of these indicators. It is found that global CO{sub 2} emissions from electricity production would be reduced by 19% if all these indicators are benchmarked at the 50th percentile. Not surprisingly, the emission reduction potential measured in absolute terms is the highest for large countries such as China, India, Russia and the United States. When the potential is expressed as a percentage of a country's own emissions, few of these countries appear in the top-five list. 14 refs., 8 figs., 4 tabs.

Global Electric Circuit Implications of Combined Aircraft Storm Electric Current Measurements and Satellite-Based Diurnal Lightning Statistics

Science.gov (United States)

Mach, Douglas M.; Blakeslee, Richard J.; Bateman, Monte G.

2011-01-01

Using rotating vane electric field mills and Gerdien capacitors, we measured the electric field profile and conductivity during 850 overflights of thunderstorms and electrified shower clouds (ESCs) spanning regions including the Southeastern United States, the Western Atlantic Ocean, the Gulf of Mexico, Central America and adjacent oceans, Central Brazil, and the South Pacific. The overflights include storms over land and ocean, and with positive and negative fields above the storms. Over three-quarters (78%) of the land storms had detectable lightning, while less than half (43%) of the oceanic storms had lightning. Integrating our electric field and conductivity data, we determined total conduction currents and flash rates for each overpass. With knowledge of the storm location (land or ocean) and type (with or without lightning), we determine the mean currents by location and type. The mean current for ocean thunderstorms is 1.7 A while the mean current for land thunderstorms is 1.0 A. The mean current for ocean ESCs 0.41 A and the mean current for land ESCs is 0.13 A. We did not find any significant regional or latitudinal based patterns in our total conduction currents. By combining the aircraft derived storm currents and flash rates with diurnal flash rate statistics derived from the Lightning Imaging Sensor (LIS) and Optical Transient Detector (OTD) low Earth orbiting satellites, we reproduce the diurnal variation in the global electric circuit (i.e., the Carnegie curve) to within 4% for all but two short periods of time. The agreement with the Carnegie curve was obtained without any tuning or adjustment of the satellite or aircraft data. Given our data and assumptions, mean contributions to the global electric circuit are 1.1 kA (land) and 0.7 kA (ocean) from thunderstorms, and 0.22 kA (ocean) and 0.04 (land) from ESCs, resulting in a mean total conduction current estimate for the global electric circuit of 2.0 kA. Mean storm counts are 1100 for land

This work analyzes different current source and conductivity parameterizations and their influence on the diurnal variation of the global electric circuit (GEC). The diurnal variations of the current source parameterizations obtained using electric field and conductivity measurements from plane overflights combined with global Tropical Rainfall Measuring Mission satellite data give generally good agreement with measured diurnal variation of the electric field at Vostok, Antarctica, where reference experimental measurements are performed. An approach employing 85 GHz passive microwave observations to infer currents within the GEC is compared and shows the best agreement in amplitude and phase with experimental measurements. To study the conductivity influence, GEC models solving the continuity equation in 3-D are used to calculate atmospheric resistance using yearly averaged conductivity obtained from the global circulation model Community Earth System Model (CESM). Then, using current source parameterization combining mean currents and global counts of electrified clouds, if the exponential conductivity is substituted by the conductivity from CESM, the peak to peak diurnal variation of the ionospheric potential of the GEC decreases from 24% to 20%. The main reason for the change is the presence of clouds while effects of 222Rn ionization, aerosols, and topography are less pronounced. The simulated peak to peak diurnal variation of the electric field at Vostok is increased from 15% to 18% from the diurnal variation of the global current in the GEC if conductivity from CESM is used.

2017-10-01

A scenario-based prognosis of the evolution of global power generation markets until 2040, which was developed using the Scaner model-and-information complex, was given. The perspective development of fuel markets, vital for the power generation industry, was considered, and an attempt to predict the demand, production, and prices of oil, gas, coal, and noncarbon resources across various regions of the world was made. The anticipated decline in the growth of the global demand for fossil fuels and their sufficiency with relatively low extraction expenses will maintain the fuel prices (the data hereinafter are given as per 2014 prices) lower than their peak values in 2012. The outrunning growth of demand for electric power is shown in comparison with other power resources by regions and large countries in the world. The conditions of interfuel competition in the electric power industry considering the changes in anticipated fuel prices and cost indicators for various power generation technologies were studied. For this purpose, the ratios of discounted costs of electric power production by new gas and coal TPPs and wind and solar power plants were estimated. It was proven that accounting the system effects (operation modes, necessary duplicating and reserving the power of electric power plants using renewable energy sources) notably reduces the competitiveness of the renewable power industry and is not always compensated by the expected lowering of its capital intensity and growth of fuel for TPPs. However, even with a moderate (in relation to other prognoses) growth of the role of power plants using renewable energy sources, they will triple electric power production. In this context, thermal power plants will preserve their leadership covering up to 60% of the global electric power production, approximately half using gas.

Given limited funds for research and widespread degradation of ecosystems, environmental scientists should geographically target their studies where they will be most effective. However, in academic areas such as conservation and natural resource management there is often a mismatch between the geographic foci of research effort/funding and research needs. The former frequently being focused in the developed world while the latter is greater in the biodiverse countries of the Global South. Here, we adopt a bibliometric approach to test this hypothesis using research on artisanal fisheries. Such fisheries occur throughout the world, but are especially prominent in developing countries where they are important for supporting local livelihoods, food security and poverty alleviation. Moreover, most artisanal fisheries in the Global South are unregulated and unmonitored and are in urgent need of science-based management to ensure future sustainability. Our results indicate that, as predicted, global research networks and centres of knowledge production are predominantly located in developed countries, indicating a global mismatch between research needs and capacity.

In the background of building global energy internet, it has both theoretical and realistic significance for forecasting and analysing the ratio of electric energy to terminal energy consumption. This paper firstly analysed the influencing factors of the ratio of electric energy to terminal energy and then used combination method to forecast and analyse the global proportion of electric energy. And then, construct the cointegration model for the proportion of electric energy by using influence factor such as electricity price index, GDP, economic structure, energy use efficiency and total population level. At last, this paper got prediction map of the proportion of electric energy by using the combination-forecasting model based on multiple linear regression method, trend analysis method, and variance-covariance method. This map describes the development trend of the proportion of electric energy in 2017-2050 and the proportion of electric energy in 2050 was analysed in detail using scenario analysis.

The policy relevance of global environmental change research

International Nuclear Information System (INIS)

Yarnal, Brent

1996-01-01

Many scientists are striving to identify and promote the policy implications of their global change research. Much basic research on global environmental change cannot advance policy directly, but new projects can determine the relevance of their research to decision makers and build policy-relevant products into the work. Similarly, many ongoing projects can alter or add to the present science design to make the research policy relevant. Thus, this paper shows scientists working on global change how to make their research policy relevant. It demonstrates how research on physical global change relates to human dimensions studies and integrated assessments. It also presents an example of how policy relevance can be fit retroactively into a global change project (in this case, SRBEX-the Susquehanna River Basin Experiment) and how that addition can enhance the project's status and science. The paper concludes that policy relevance is desirable from social and scientific perspectives

Electrical and electronic waste: a global environmental problem.

Science.gov (United States)

Ramesh Babu, Balakrishnan; Parande, Anand Kuber; Ahmed Basha, Chiya

2007-08-01

The production of electrical and electronic equipment (EEE) is one of the fastest growing global manufacturing activities. This development has resulted in an increase of waste electric and electronic equipment (WEEE). Rapid economic growth, coupled with urbanization and growing demand for consumer goods, has increased both the consumption of EEE and the production of WEEE, which can be a source of hazardous wastes that pose a risk to the environment and to sustainable economic growth. To address potential environmental problems that could stem from improper management of WEEE, many countries and organizations have drafted national legislation to improve the reuse, recycling and other forms of material recovery from WEEE to reduce the amount and types of materials disposed in landfills. Recycling of waste electric and electronic equipment is important not only to reduce the amount of waste requiring treatment, but also to promote the recovery of valuable materials. EEE is diverse and complex with respect to the materials and components used and waste streams from the manufacturing processes. Characterization of these wastes is of paramount importance for developing a cost-effective and environmentally sound recycling system. This paper offers an overview of electrical and e-waste recycling, including a description of how it is generated and classified, strategies and technologies for recovering materials, and new scientific developments related to these activities. Finally, the e-waste recycling industry in India is also discussed.

Travelling Methods: Tracing the Globalization of Qualitative Communication Research

2016-05-01

Full Text Available Existing discussion of the relationships between globalization, communication research, and qualitative methods emphasizes two images: the challenges posed by globalization to existing communication theory and research methods, and the impact of post-colonial politics and ethics on qualitative research. We draw in this paper on a third image – qualitative research methods as artifacts of globalization – to explore the globalization of qualitative communication research methods. Following a review of literature which tentatively models this process, we discuss two case studies of qualitative research in the disciplinary subfields of intercultural communication and media audience studies. These cases elaborate the forces which influence the articulation of national, disciplinary, and methodological identities which mediate the globalization of qualitative communication research methods.

A global model of thunderstorm electricity and the prediction of whistler duct formation

International Nuclear Information System (INIS)

Stansbery, E.K.

1989-01-01

A two-dimensional numerical model is created to calculate the electric field and current that flow from a thunderstorm source into the global electrical circuit. The model includes a hemisphere in which the thunderstorm is located, an equalization layer, and a passive magnetic conjugate hemisphere. To maintain the fair weather electric field, the output current from the thunderstorm is allowed to spread out in the ionosphere or flow along the magnetic field lines into the conjugate hemisphere. The vertical current is constant up to approximately 65 km, decays and is redirected horizontally in the ionosphere. Approximately half of the current that reaches the ionosphere flows along magnetic field lines into the conjugate hemisphere while the rest is spread out in the ionosphere and redirected to the fair weather portion of the storm hemisphere. Our results show that it is important to include a realistic model of the equalization layer to evaluate the role of thunderstorm charging of the global circuit. The mapping of thunderstorm electric fields at middle and subauroral latitudes into the magnetic equatorial plane is studied. The geomagnetic field lines are assumed to be dipolar above approximately 150 km. The horizontal electric field computed in the ionosphere by our model is of sufficient size and shape for the formation of electron density irregularities in the magnetosphere. The mechanism involves a localized convection of ionization tubes by ExB drift. It is shown that the horizontal range of the electric field disturbance in the ionosphere must be within approximately 160 km to produce density irregularities necessary for the formation of whistler ducts. Although the electric field strength at ionospheric heights depends sensitively on the conductivity profile, the results presented show that whistler duct formation is possible by thunderstorm generated electric fields.*

The Workshop on Uncertainty and Global Climate Change Research March 22--23, 1994, in Knoxville, Tennessee. This report summarizes the results and recommendations of the workshop. The purpose of the workshop was to examine in-depth the concept of uncertainty. From an analytical point of view, uncertainty is a central feature of global climate science, economics and decision making. The magnitude and complexity of uncertainty surrounding global climate change has made it quite difficult to answer even the most simple and important of questions-whether potentially costly action is required now to ameliorate adverse consequences of global climate change or whether delay is warranted to gain better information to reduce uncertainties. A major conclusion of the workshop is that multidisciplinary integrated assessments using decision analytic techniques as a foundation is key to addressing global change policy concerns. First, uncertainty must be dealt with explicitly and rigorously since it is and will continue to be a key feature of analysis and recommendations on policy questions for years to come. Second, key policy questions and variables need to be explicitly identified, prioritized, and their uncertainty characterized to guide the entire scientific, modeling, and policy analysis process. Multidisciplinary integrated assessment techniques and value of information methodologies are best suited for this task. In terms of timeliness and relevance of developing and applying decision analytic techniques, the global change research and policy communities are moving rapidly toward integrated approaches to research design and policy analysis.

The global atmospheric electric circuit and its effects on cloud microphysics

Tinsley, B A

2008-01-01

This review is an overview of progress in understanding the theory and observation of the global atmospheric electric circuit, with the focus on its dc aspects, and its short and long term variability. The effects of the downward ionosphere-earth current density, J z , on cloud microphysics, with its variability as an explanation for small observed changes in weather and climate, will also be reviewed. The global circuit shows responses to external as well as internal forcing. External forcing arises from changes in the distribution of conductivity due to changes in the cosmic ray flux and other energetic space particle fluxes, and at high magnetic latitudes from solar wind electric fields. Internal forcing arises from changes in the generators and changes in volcanic and anthropogenic aerosols in the troposphere and stratosphere. All these result in spatial and temporal variation in J z . Variations in J z affect the production of space charge in layer clouds, with the charges being transferred to droplets and aerosol particles. New observations and new analyses are consistent with non-negligible effects of the charges on the microphysics of such clouds. Observed effects are small, but of high statistical significance for cloud cover and precipitation changes, with resulting atmospheric temperature, pressure and dynamics changes. These effects are detectable on the day-to-day timescale for repeated J z changes of order 10%, and are thus second order electrical effects. The implicit first order effects have not, as yet, been incorporated into basic cloud and aerosol physics. Long term (multidecadal through millennial) global circuit changes, due to solar activity modulating the galactic cosmic ray flux, are an order of magnitude greater at high latitudes and in the stratosphere, as can be inferred from geological cosmogenic isotope records. Proxies for climate change in the same stratified depositories show strong correlations of climate with the inferred global

This review is an overview of progress in understanding the theory and observation of the global atmospheric electric circuit, with the focus on its dc aspects, and its short and long term variability. The effects of the downward ionosphere-earth current density, J{sub z}, on cloud microphysics, with its variability as an explanation for small observed changes in weather and climate, will also be reviewed. The global circuit shows responses to external as well as internal forcing. External forcing arises from changes in the distribution of conductivity due to changes in the cosmic ray flux and other energetic space particle fluxes, and at high magnetic latitudes from solar wind electric fields. Internal forcing arises from changes in the generators and changes in volcanic and anthropogenic aerosols in the troposphere and stratosphere. All these result in spatial and temporal variation in J{sub z}.

Infectious diseases account for a significant global burden of disease and substantial investment in research and development. This paper presents a systematic assessment of research investments awarded to UK institutions and global health metrics assessing disease burden. We systematically sourced research funding data awarded from public and philanthropic organisations between 1997 and 2013. We screened awards for relevance to infection and categorised data by type of science, disease area and specific pathogen. Investments were compared with mortality, disability-adjusted life years (DALYs) and years lived with disability (YLD) across three time points. Between 1997-2013, there were 7398 awards with a total investment of £3.7 billion. An increase in research funding across 2011-2013 was observed for most disease areas, with notable exceptions being sexually transmitted infections and sepsis research where funding decreased. Most funding remains for pre-clinical research (£2.2 billion, 59.4%). Relative to global mortality, DALYs and YLDs, acute hepatitis C, leishmaniasis and African trypanosomiasis received comparatively high levels of funding. Pneumonia, shigellosis, pertussis, cholera and syphilis were poorly funded across all health metrics. Tuberculosis (TB) consistently attracts relatively less funding than HIV and malaria. Most infections have received increases in research investment, alongside decreases in global burden of disease in 2013. The UK demonstrates research strengths in some neglected tropical diseases such as African trypanosomiasis and leishmaniasis, but syphilis, cholera, shigellosis and pneumonia remain poorly funded relative to their global burden. Acute hepatitis C appears well funded but the figures do not adequately take into account projected future chronic burdens for this condition. These findings can help to inform global policymakers on resource allocation for research investment.

2005-01-01

A methodology developed to evaluate the sustainability of sources of electric generation but used in Mexico and in the World is presented. For it was applied one matrix of sustainability indicators that considers the principles and criteria of general sustainability as 'not exhaustion of natural resources', 'non production of non degradable waste', and 'not high sensibility to social and environmental factors'. The approaches to evaluate in a wide way these principles are numerous and to each approach associates an indicator, call sustainability indicator. The contribution of this work consists on the development of a methodology to qualify globally the sustainability of each option of electric generation, combining all the sustainability indicators. The methodology applies a system of diffuse control to build the function of global qualification of sustainability dependent of all the indicators. (Author)

The ability to provide optimal care to cancer patients depends on awareness of current evidence-based practices emanating from research or involvement in research where circumstances permit. The significant global variations in cancer-related research activity and its correlation to cancer-specific outcomes may have an influence on the care provided to cancer patients and their outcomes. The aim of this project is to develop a global curriculum in research literacy for the surgical oncologist. The leadership of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in research literacy for the Surgical Oncologist. A global curriculum in research literacy is developed to incorporate the required domains considered to be essential to interpret the published research or become involved in research activity where circumstances permit. The purpose of this curriculum is to promote research literacy for the surgical oncologist, wherever they are based. It does not mandate direct research participation which may not be feasible due to restrictions within the local health-care delivery environment, socio-economic priorities and the educational environment of the individual institution where they work. A global curriculum in research literacy is proposed which may promote research literacy or encourage involvement in research activity where circumstances permit. It is hoped that this will enhance cancer-related research activity, promote awareness of optimal evidence-based practices and improve outcomes for cancer patients globally.

Energy balance of the global photovoltaic (PV) industry--is the PV industry a net electricity producer?

Science.gov (United States)

Dale, Michael; Benson, Sally M

2013-04-02

A combination of declining costs and policy measures motivated by greenhouse gas (GHG) emissions reduction and energy security have driven rapid growth in the global installed capacity of solar photovoltaics (PV). This paper develops a number of unique data sets, namely the following: calculation of distribution of global capacity factor for PV deployment; meta-analysis of energy consumption in PV system manufacture and deployment; and documentation of reduction in energetic costs of PV system production. These data are used as input into a new net energy analysis of the global PV industry, as opposed to device level analysis. In addition, the paper introduces a new concept: a model tracking energetic costs of manufacturing and installing PV systems, including balance of system (BOS) components. The model is used to forecast electrical energy requirements to scale up the PV industry and determine the electricity balance of the global PV industry to 2020. Results suggest that the industry was a net consumer of electricity as recently as 2010. However, there is a >50% that in 2012 the PV industry is a net electricity provider and will "pay back" the electrical energy required for its early growth before 2020. Further reducing energetic costs of PV deployment will enable more rapid growth of the PV industry. There is also great potential to increase the capacity factor of PV deployment. These conclusions have a number of implications for R&D and deployment, including the following: monitoring of the energy embodied within PV systems; designing more efficient and durable systems; and deploying PV systems in locations that will achieve high capacity factors.

Data management and global change research: Technology and infrastructure

Morrissey, W.A.

1993-01-01

There is a consensus among many scientists who would perform global change research that global-scale scientific data management programs and enabling policies need to be developed and implemented concomitantly with, if not in advance of, global change research programs. They are hopeful that US Federal government policies for scientific and technical data and information management will provide timely archival, analysis, and dissemination of global change research data and will enable them to share that data with colleagues, internationally. Federal data managers believe that data management technology and infrastructure requirements for global change research programs can be met through existing or planned enhancements to systems in operation used for scientific data gathering, processing, and dissemination. Scientists are concerned, however, that because of the scope and diversity of global change research programs entirely new systems and approaches to data management may need to be devised

The global electrical circuit, which maintains a potential of about 280??kV between the earth and the ionosphere, is thought to be driven mainly by thunderstorms and lightning. However, very few in situ measurements of electrical current above thunderstorms have been successfully obtained. In this paper, we present dc to very low frequency electric fields and atmospheric conductivity measured in the stratosphere (30-35??km altitude) above an active thunderstorm in southeastern Brazil. From these measurements, we estimate the mean quasi-static conduction current during the storm period to be 2.5 ?? 1.25??A. Additionally, we examine the transient conduction currents following a large positive cloud-to-ground (+ CG) lightning flash and typical - CG flashes. We find that the majority of the total current is attributed to the quasi-static thundercloud charge, rather than lightning, which supports the classical Wilson model for the global electrical circuit.

The first book studies on the economics of electricity consumption. Compares the sector production functions with electricity and the commercial production functions with electricity. Introduces the global E-GDP function, the European E-GDP function and 12 national E-GDP functions. Presents the gene characters of EAI production functions and E-GDP functions for USA to see why USA's economy is entering an up-industrialization period. Discusses China's economic growth by production functions with electricity. Electricity Economics: Production Functions with Electricity studies the production output from analyzing patterns of electricity consumption. Since electricity data can be used to measure scenarios of economic performance due to its accuracy and reliability, it could therefore also be used to help scholars explore new research frontiers that directly and indirectly benefits human society. Our research initially explores a similar pattern to substitute the Cobb-Douglas function with the production function with electricity to track and forecast economic activities. The book systematically introduces the theoretical frameworks and mathematical models of economics from the perspective of electricity consumption. The E-GDP functions are presented for case studies of more than 20 developed and developing countries. These functions also demonstrate substantial similarities between human DNA and production functions with electricity in terms of four major characteristics, namely replication, mutation, uniqueness, and evolution. Furthermore, the book includes extensive data and case studies on the U.S., China, Japan, etc. It is intended for scientists, engineers, financial professionals, policy makers, consultants, and anyone else with a desire to study electricity economics as well as related applications.

Full Text Available There has been a dramatic rise in the scale and scope of collaborative global health research. A number of structural and scientific factors explain this growth and there has been much discussion of these in the literature. Little, if any, attention has been paid, however, to the factors identified by scientists and other research actors as important to successful research collaboration. This is surprising given that their decisions are likely to play a key role in the sustainability and effectiveness of global health research initiatives. In this paper, we report on qualitative research with leading scientists involved in major international research collaborations about their views on good and bad collaborations and the factors that inform their decision-making about joining and participating actively in research networks. We identify and discuss eight factors that researchers see as essential in judging the merits of active participation in global health research collaborations: opportunities for active involvement in cutting-edge, interesting science; effective leadership; competence of potential partners in and commitment to good scientific practice; capacity building; respect for the needs, interests and agendas of partners; opportunities for discussion and disagreement; trust and confidence; and, justice and fairness in collaboration. Our findings suggest that the sustainability and effectiveness of global health research collaborations has an important ethical or moral dimension for the research actors involved.

Full Text Available The rising number of vehicles over the years has driven the increase of air pollution and fuel consumption. One of the solutions to overcome this problem is using hybrid electric car because it is environmentally friendly and efficient in fuel consumption. LIPI has conducted electric car research since 1997, but there were so many problems in its development that electric car can not be developed into a national industry scale. Therefore, it is important to conduct a study that maps the problems and finds the solutions to prevent the same failure of electric car commercialization process from happening to hybrid electric car . This study was done by collecting and analyzing the primary and secondary data through interviews, discussing electric hybrid car with stakeholders, and examining earlier study results and regulations. Based on this study, several policies to support sustainability research of hybrid electric car were proposed. Some recommendations were the making of national roadmap and regulation for the usage of hybrid electric car on the road. For policy makers at LIPI, a research focus, research coordination, and pre-commercialization program were recommended.

Examining the resilience of national energy systems: Measurements of diversity in production-based and consumption-based electricity in the globalization of trade networks

Energy is a critical component of achieving sustainable development. In addition to the three aspects of promoting access, renewables, and efficiency, the dimension of resilience in energy systems should also considered. The implementation of resilient energy systems requires a quantitative understanding of the socio-economic practices underlying such systems. Specifically, in line with the increasing globalization of trade, there remains a critical knowledge gap on the link between embodied energy in the production and consumption of traded goods. To bridge this knowledge gap, we investigate the resilience of global energy systems through an examination of a diversity measure of global embodied electricity trade based on multi-regional input-output (MRIO) networks. The significance of this research lies in its ability to utilize high resolution MRIO data sets in assessing the resilience of national energy systems. This research indicates that secure and responsible consumption requires the diversification of not only energy generation but also energy imports. This research will lay the ground for further research in the governance of resilience in global energy networks. - Highlights: • We examine the resilience of global embodied energy based on (MRIO) trade networks. • We propose a secure and responsible mode of thinking for national energy consumption. • Secure & responsible consumption requires diversity in energy generation and imports.

Examining global electricity supply vulnerability to climate change using a high-fidelity hydropower dam model.

Turner, Sean W D; Ng, Jia Yi; Galelli, Stefano

2017-07-15

An important and plausible impact of a changing global climate is altered power generation from hydroelectric dams. Here we project 21st century global hydropower production by forcing a coupled, global hydrological and dam model with three General Circulation Model (GCM) projections run under two emissions scenarios. Dams are simulated using a detailed model that accounts for plant specifications, storage dynamics, reservoir bathymetry and realistic, optimized operations. We show that the inclusion of these features can have a non-trivial effect on the simulated response of hydropower production to changes in climate. Simulation results highlight substantial uncertainty in the direction of change in globally aggregated hydropower production (~-5 to +5% change in mean global production by the 2080s under a high emissions scenario, depending on GCM). Several clearly impacted hotspots are identified, the most prominent of which encompasses the Mediterranean countries in southern Europe, northern Africa and the Middle East. In this region, hydropower production is projected to be reduced by approximately 40% on average by the end of the century under a high emissions scenario. After accounting for each country's dependence on hydropower for meeting its current electricity demands, the Balkans countries emerge as the most vulnerable (~5-20% loss in total national electricity generation depending on country). On the flipside, a handful of countries in Scandinavia and central Asia are projected to reap a significant increase in total electrical production (~5-15%) without investing in new power generation facilities.

Global status of hydrogen research

Lakeman, J.B.; Browning, D.J.

2001-07-01

This report surveys the global status of hydrogen research and identifies technological barriers to the implementation of a global hydrogen economy. It is concluded that there will be a 30 year transition phase to the full implementation of the hydrogen economy. In this period, hydrogen will be largely produced by the reformation of hydrocarbons, particularly methane. It will be necessary to ensure that any carbonaceous oxides (and other unwanted species) formed as by-products will be trapped and not released into the atmosphere. Following the transition phase, hydrogen should be largely produced from renewable energy sources using some form of water cracking, largely electrolysis. Target performances and costs are identified for key technologies. The status of hydrogen research in the UK is reviews and it is concluded that the UK does not have a strategy for the adoption of the hydrogen economy, nor does it have a coherent and co-ordinated research and development strategy addressing barriers to the hydrogen economy. Despite this fact, because of the long transition phase, it is still possible for the UK to formulate a coherent strategy and make a significant contribution to the global implementation of the hydrogen economy, as there are still unresolved technology issues. The report concludes with a number of recommendations. (Author)

Global electric-field determination in the Earth's outer magnetosphere using charged particles. Progress Report No. 1, 1991

Eastman, T.; Sheldon, R.; Hamilton, D.; Mcilwain, C.

1992-03-01

Although many properties of the Earth's magnetosphere have been measured and quantified in the past 30 years since it was discovered, one fundamental (for a zeroeth order magnetohydrodynamic (MHD) equilibrium) measurement was made infrequently and with poor spatial coverage: the global electric field. This oversight is in part due to the difficulty of measuring a plasma electric field, and in part due to the difficulty of measuring a plasma electric field, and in part due to the neglect of theorists. However, there is renewed interest in the convection electric field, since it has been realized that it is vital for understanding many aspects of the magnetosphere: the global MHD equilibrium, reconnection rates, Region 2 Birkeland currents, magnetosphere-ionosphere coupling, ring current and radiation belt transport, substorm injections, acceleration mechanisms, etc. Unfortunately the standard experimental methods have not been able to synthesize a global field (excepting the pioneering work of McIlwain's geostationary models), and we are left with an overly simplistic theoretical field, the Volland-Stern electric field mode. Again, single point measurements of the plasma pause were used to infer the appropriate amplitudes of the model, parameterized by Kp (Maynard and Chen, JGR 1975). Although this result was never intended to be the definitive electric field model, it has gone nearly unchanged for 15 years. However, the data sets being taken today require a great deal more accuracy than can be provided by the Volland-Stern model. Nor has the variability of the electric field shielding been properly addressed, although effects of penetrating magnetospheric electric fields has been seen in mid- and low-latitude ionospheric data sets. The growing interests in substorm dynamics also requires a much better assessment of the electric fields responsible for particle injections

Dynamics of global supply chain and electric power networks: Models, pricing analysis, and computations

Science.gov (United States)

Matsypura, Dmytro

In this dissertation, I develop a new theoretical framework for the modeling, pricing analysis, and computation of solutions to electric power supply chains with power generators, suppliers, transmission service providers, and the inclusion of consumer demands. In particular, I advocate the application of finite-dimensional variational inequality theory, projected dynamical systems theory, game theory, network theory, and other tools that have been recently proposed for the modeling and analysis of supply chain networks (cf. Nagurney (2006)) to electric power markets. This dissertation contributes to the extant literature on the modeling, analysis, and solution of supply chain networks, including global supply chains, in general, and electric power supply chains, in particular, in the following ways. It develops a theoretical framework for modeling, pricing analysis, and computation of electric power flows/transactions in electric power systems using the rationale for supply chain analysis. The models developed include both static and dynamic ones. The dissertation also adds a new dimension to the methodology of the theory of projected dynamical systems by proving that, irrespective of the speeds of adjustment, the equilibrium of the system remains the same. Finally, I include alternative fuel suppliers, along with their behavior into the supply chain modeling and analysis framework. This dissertation has strong practical implications. In an era in which technology and globalization, coupled with increasing risk and uncertainty, complicate electricity demand and supply within and between nations, the successful management of electric power systems and pricing become increasingly pressing topics with relevance not only for economic prosperity but also national security. This dissertation addresses such related topics by providing models, pricing tools, and algorithms for decentralized electric power supply chains. This dissertation is based heavily on the following

Interpretation: Most infections have received increases in research investment, alongside decreases in global burden of disease in 2013. The UK demonstrates research strengths in some neglected tropical diseases such as African trypanosomiasis and leishmaniasis, but syphilis, cholera, shigellosis and pneumonia remain poorly funded relative to their global burden. Acute hepatitis C appears well funded but the figures do not adequately take into account projected future chronic burdens for this condition. These findings can help to inform global policymakers on resource allocation for research investment.

Combined Aircraft and Satellite-Derived Storm Electric Current and Lightning Rates Measurements and Implications for the Global Electric Circuit

Mach, Douglas M.; Blakeslee, Richard J.; Bateman, Monte G.

Using rotating vane electric field mills and Gerdien capacitors, we measured the electric field profile and conductivity during 850 overflights of electrified shower clouds and thunderstorms spanning regions including the Southeastern United States, the Western Atlantic Ocean, the Gulf of Mexico, Central America and adjacent oceans, Central Brazil, and the South Pacific. The overflights include storms over land and ocean, with and without lightning, and with positive and negative fields above the storms. The measurements were made with the NASA ER-2 and the Altus-II high altitude aircrafts. Peak electric fields, with lightning transients removed, ranged from -1.0 kV/m to 16 kV/m, with a mean value of 0.9 kV/m. The median peak field was 0.29 kV/m. Integrating our electric field and conductivity data, we determined total conduction currents and flash rates for each overpass. With knowledge of the storm location (land or ocean) and type (with or without lightning), we determine the mean currents by location and type. The mean current for ocean storms with lightning is 1.6 A while the mean current for land storms with lightning is 1.0 A. The mean current for oceanic storms without lightning (i.e., electrified shower clouds) is 0.39 A and the mean current for land storms without lightning is 0.13 A. Thus, on average, land storms with or without lightning have about half the mean current as their corresponding oceanic storm counterparts. Over three-quarters (78%) of the land storms had detectable lightning, while less than half (43%) of the oceanic storms had lightning. We did not find any significant regional or latitudinal based patterns in our total conduction currents. By combining the aircraft derived storm currents and flash rates with diurnal lightning statistics derived from the Lightning Imaging Sensor (LIS) and Optical Transient Detector (OTD) low Earth orbiting satellites, we reproduce the diurnal variation in the global electric circuit (i.e., the Carnegie

Background Infectious diseases account for a significant global burden of disease and substantial investment in research and development. This paper presents a systematic assessment of research investments awarded to UK institutions and global health metrics assessing disease burden. Methods We systematically sourced research funding data awarded from public and philanthropic organisations between 1997 and 2013. We screened awards for relevance to infection and categorised data by type of science, disease area and specific pathogen. Investments were compared with mortality, disability-adjusted life years (DALYs) and years lived with disability (YLD) across three time points. Findings Between 1997–2013, there were 7398 awards with a total investment of £3.7 billion. An increase in research funding across 2011–2013 was observed for most disease areas, with notable exceptions being sexually transmitted infections and sepsis research where funding decreased. Most funding remains for pre-clinical research (£2.2 billion, 59.4%). Relative to global mortality, DALYs and YLDs, acute hepatitis C, leishmaniasis and African trypanosomiasis received comparatively high levels of funding. Pneumonia, shigellosis, pertussis, cholera and syphilis were poorly funded across all health metrics. Tuberculosis (TB) consistently attracts relatively less funding than HIV and malaria. Interpretation Most infections have received increases in research investment, alongside decreases in global burden of disease in 2013. The UK demonstrates research strengths in some neglected tropical diseases such as African trypanosomiasis and leishmaniasis, but syphilis, cholera, shigellosis and pneumonia remain poorly funded relative to their global burden. Acute hepatitis C appears well funded but the figures do not adequately take into account projected future chronic burdens for this condition. These findings can help to inform global policymakers on resource allocation for research investment

Europe in the global race for electrical batteries

International Nuclear Information System (INIS)

Mathieu, Carole

2017-07-01

This study weighs up the different strategic approaches that Europe may adopt in the industrial race for electrical batteries, taking into account the demand potential for e-mobility and stationary storage, the global competitive landscape and the policy support for local players in Asia and the U.S. The future looks bright for battery storage technologies. They could be the answer to the grid constraints that come with the rise of intermittent renewable electricity, while opening the door to the electrification of the transport sector and a reduction of its carbon footprint. Significant improvements in terms of performance and manufacturing costs have been achieved in recent years, thanks to the development of portable electronic devices and the push for lithium-ion solutions. The prospect of widening the client base to the automobile and energy industries is now triggering a massive wave of investment in battery manufacturing capacities. Economies of scale and increasing pressure on margins should make battery technologies even more affordable, and facilitate their adoption beyond public support schemes. A true industrial race is launched, but it takes place primarily in Asia, and to a lesser extent in North America. In these regions, public authorities are already proactive in promoting local industrial players on a global market that is buoyant but still highly risky. Unless the European Union reacts swiftly, it could see its internal demand being primarily covered by non-European manufacturers. While the EU has strong academic and industrial assets in the battery field, it risks being left behind the new mass markets if it proves unable to support the European battery industry with concerted efforts. The challenge is twofold: seizing a major opportunity in terms of growth and job creation, while preventing the emergence of major technology dependence

Comment on 'Current Budget of the Atmospheric Electric Global Circuit'

Science.gov (United States)

Driscoll, Kevin T.; Blakeslee, Richard J.

1996-01-01

In this paper, three major issues relevant to Kasemir's new model will be addressed. The first concerns Kasemir's assertion that there are significant differences between the potentials associated with the new model and the conventional model. A recalculation of these potentials reveals that both models provide equivalent results for the potential difference between the Earth and ionosphere. The second issue to be addressed is Kasemir's assertion that discrepancies in the electric potentials associated with both models can be attributed to modeling the Earth as a sphere, instead of as a planar surface. A simple analytical comparison will demonstrate that differences in the equations for the potentials of the atmosphere derived with a spherical and a planar Earth are negligible for applications to global current flow. Finally, the third issue to be discussed is Kasemir's claim that numerous aspects of the conventional model are incorrect, including the role of the ionosphere in global current flow as well as the significance of cloud-to-ground lightning in supplying charge to the global circuit. In order to refute these misconceptions, it will be shown that these aspects related to the flow of charge in the atmosphere are accurately described by the conventional model of the global circuit.

2013-01-01

Full Text Available Energy management strategy influences the power performance and fuel economy of plug-in hybrid electric vehicles greatly. To explore the fuel-saving potential of a plug-in hybrid electric bus (PHEB, this paper searched the global optimal energy management strategy using dynamic programming (DP algorithm. Firstly, the simplified backward model of the PHEB was built which is necessary for DP algorithm. Then the torque and speed of engine and the torque of motor were selected as the control variables, and the battery state of charge (SOC was selected as the state variables. The DP solution procedure was listed, and the way was presented to find all possible control variables at every state of each stage in detail. Finally, the appropriate SOC increment is determined after quantizing the state variables, and then the optimal control of long driving distance of a specific driving cycle is replaced with the optimal control of one driving cycle, which reduces the computational time significantly and keeps the precision at the same time. The simulation results show that the fuel economy of the PEHB with the optimal energy management strategy is improved by 53.7% compared with that of the conventional bus, which can be a benchmark for the assessment of other control strategies.

Electric vehicles (EVs) hold the potential of transforming the way the world moves. EVs can increase energy security by diversifying the fuel mix and decreasing dependence on petroleum, while also reducing emissions of greenhouse gases and other pollutants. Just as important, EVs can unlock innovation and create new advanced industries that spur job growth and enhance economic prosperity. However, the mass deployment of EVs will require transportation systems capable of integrating and fostering this new technology. To accelerate this transition, cities and metropolitan regions around the world are creating EV-friendly ecosystems and building the foundation for widespread adoption. In recognition of the importance of urban areas in the introduction and scale-up of electric vehicles, the EV City Casebook presents informative case studies on city and regional EV deployment efforts around the world. These case studies are illustrative examples of how pioneering cities are preparing the ground for mass market EV deployment. They offer both qualitative and quantitative information on cities' EV goals, progress, policies, incentives, and lessons learned to date. The purpose of the EV City Casebook is to share experiences on EV demonstration and deployment, identify challenges and opportunities, and highlight best practices for creating thriving EV ecosystems. These studies seek to enhance understanding of the most effective policy measures to foster the uptake of electric vehicles in urban areas. The cities represented here are actively engaging in a variety of initiatives that share the goal of accelerating EV adoption. This publication is the result of an effort to coordinate those initiatives and provide a global perspective on the electric vehicle movement.

The burden of cardiovascular disease (CVD) in Canada and other developed countries is growing, in part because of the aging of the population and the alarming rise of obesity. Studying Canada's contribution to the global body of CVD research output will shed light on the effectiveness of investments in Canadian CVD research and inform if Canada has been responding to its CVD burden. Search was conducted using the Web-of-Science database for publications during 1981 through 2010 on major areas and specific interventions in CVD. Search was also conducted using Canadian and US online databases for patents issued between 1981 and 2010. Search data were used to estimate the proportions of the world's pool of research publications and of patents conducted by researchers based in Canada. The results indicate that Canada contributed 6% of global research in CVD during 1981 through 2010. Further, Canada's contribution shows a strong upward trend during the period. Based on patent data, Canada's contribution level was similar (5%-7%). Canada's contribution to the global pool of CVD research is on par with France and close to the UK, Japan, and Germany. Canada's contribution in global CVD research is higher than its average contribution in all fields of research (6% vs 3%). As the burden of chronic diseases including CVD rises with Canada's aging population, the increase in Canadian research into CVD is encouraging. Copyright © 2013 Canadian Cardiovascular Society.

Global health research in resource-limited countries has been largely sponsored and led by foreign institutions. Thus, these countries' training capacity and productivity in global health research is limited. Local participation at all levels of global health knowledge generation promotes equitable access to evidence-based solutions. Additionally, leadership inclusive of competent local professionals promotes best outcomes for local contextualization and implementation of successful global health solutions. Among the sub-Saharan African regions, West Africa in particular lags in research infrastructure, productivity, and impact in global health research. In this paper, experts discuss strategies for scaling up West Africa's participation in global health evidence generation using examples from Ghana and Nigeria. We conducted an online and professional network search to identify grants awarded for global health research and research education in Ghana and Nigeria. Principal investigators, global health educators, and representatives of funding institutions were invited to add their knowledge and expertise with regard to strengthening research capacity in West Africa. While there has been some progress in obtaining foreign funding, foreign institutions still dominate local research. Local research funding opportunities in the 2 countries were found to be insufficient, disjointed, poorly sustained, and inadequately publicized, indicating weak infrastructure. As a result, research training programs produce graduates who ultimately fail to launch independent investigator careers because of lack of mentoring and poor infrastructural support. Research funding and training opportunities in Ghana and Nigeria remain inadequate. We recommend systems-level changes in mentoring, collaboration, and funding to drive the global health research agenda in these countries. Additionally, research training programs should be evaluated not only by numbers of individuals graduated but

Development of Global Change Research in Developing Countries

Ecosystems and Global Change in the Context of the Neotropics; Medellín, Colombia, 19-20 May 2010; Research in most areas of global environmental change is overwhelmingly produced outside developing countries, which are usually consumers rather than producers of the knowledge associated with their natural resources. While there have been important recent advances in understanding the causes of global-¬scale changes and their consequences to the functioning of tropical ecosystems, there is still an important gap in the understanding of these changes at regional and national levels (where important political decisions are usually made). A symposium was held with the aim of surveying the current state of research activities in a small, developing country such as Colombia. It was jointly organized by the Research Center on Ecosystems and Global Change, Carbono and Bosques; the National University of Colombia at Medellín and the Colombian Ministry of the Environment, Housing, and Regional Development. This 2-¬day symposium gathered Colombian and international scientists involved in different areas of global environmental change, tropical ecosystems, and human societies.

Simulation of the Universal-Time Diurnal Variation of the Global Electric Circuit Charging Rate

Mackerras, D.; Darvenzia, M.; Orville, R. E.; Williams, E. R.; Goodman, S. J.

1999-01-01

A global lightning model that includes diurnal and annual lightning variation, and total flash density versus latitude for each major land and ocean, has been used as the basis for simulating the global electric circuit charging rate. A particular objective has been to reconcile the difference in amplitude ratios [AR=(max-min)/mean] between global lightning diurnal variation (AR approx. = 0.8) and the diurnal variation of typical atmospheric potential gradient curves (AR approx. = 0.35). A constraint on the simulation is that the annual mean charging current should be about 1000 A. The global lightning model shows that negative ground flashes can contribute, at most, about 10-15% of the required current. For the purpose of the charging rate simulation, it was assumed that each ground flash contributes 5 C to the charging process. It was necessary to assume that all electrified clouds contribute to charging by means other than lightning, that the total flash rate can serve as an indirect indicator of the rate of charge transfer, and that oceanic electrified clouds contribute to charging even though they are relatively inefficient in producing lightning. It was also found necessary to add a diurnally invariant charging current component. By trial and error it was found that charging rate diurnal variation curves in Universal time (UT) could be produced with amplitude ratios and general shapes similar to those of the potential gradient diurnal variation curves measured over ocean and arctic regions during voyages of the Carnegie Institute research vessels.

The market shares of the Top 10 companies were above fifty per cent of the research market’s turnover. As a young, modest market, which is 0,84% of the global expenses value, Romania was the global leader in terms of growth, in 2004. With an asymmetric demand and a relatively concentrated offer, the Romanian research market may have a spectacular development in the future, if the obstacles for the customers and research companies are surpassed. If so, the pressures following the UE’s entry of Romania and the evolution of customers needs and expectations will speed up the growth of the market research.

The goal of this research is the design and development of an integrated system for the management of very large scientific databases, cartographic/geographic information processing, and exploratory scientific data analysis for global change research. The system will represent both spatial and temporal knowledge about natural and man-made entities on the eath's surface, following an object-oriented paradigm. A user will be able to derive, modify, and apply, procedures to perform operations on the data, including comparison, derivation, prediction, validation, and visualization. This work represents an effort to extend the database technology with an intrinsic class of operators, which is extensible and responds to the growing needs of scientific research. Of significance is the integration of many diverse forms of data into the database, including cartography, geography, hydrography, hypsography, images, and urban planning data. Equally important is the maintenance of metadata, that is, data about the data, such as coordinate transformation parameters, map scales, and audit trails of previous processing operations. This project will impact the fields of geographical information systems and global change research as well as the database community. It will provide an integrated database management testbed for scientific research, and a testbed for the development of analysis tools to understand and predict global change.

Multistage and multiobjective formulations of globally optimal upgradable expansions for electric power distribution systems

Science.gov (United States)

Vaziri Yazdi Pin, Mohammad

Electric power distribution systems are the last high voltage link in the chain of production, transport, and delivery of the electric energy, the fundamental goals of which are to supply the users' demand safely, reliably, and economically. The number circuit miles traversed by distribution feeders in the form of visible overhead or imbedded underground lines, far exceed those of all other bulk transport circuitry in the transmission system. Development and expansion of the distribution systems, similar to other systems, is directly proportional to the growth in demand and requires careful planning. While growth of electric demand has recently slowed through efforts in the area of energy management, the need for a continued expansion seems inevitable for the near future. Distribution system and expansions are also independent of current issues facing both the suppliers and the consumers of electrical energy. For example, deregulation, as an attempt to promote competition by giving more choices to the consumers, while it will impact the suppliers' planning strategies, it cannot limit the demand growth or the system expansion in the global sense. Curiously, despite presence of technological advancements and a 40-year history of contributions in the area, many of the major utilities still relay on experience and resort to rudimentary techniques when planning expansions. A comprehensive literature review of the contributions and careful analyses of the proposed algorithms for distribution expansion, confirmed that the problem is a complex, multistage and multiobjective problem for which a practical solution remains to be developed. In this research, based on the 15-year experience of a utility engineer, the practical expansion problem has been clearly defined and the existing deficiencies in the previous work identified and analyzed. The expansion problem has been formulated as a multistage planning problem in line with a natural course of development and industry

As telehealth plays an even greater role in global health care delivery, it will be increasingly important to develop a strong evidence base of successful, innovative telehealth solutions that can lead to scalable and sustainable telehealth programs. This paper has two aims: (1) to describe the challenges of promoting telehealth implementation to advance adoption and (2) to present a global research agenda for personalized telehealth within chronic disease management. Using evidence from the United States and the European Union, this paper provides a global overview of the current state of telehealth services and benefits, presents fundamental principles that must be addressed to advance the status quo, and provides a framework for current and future research initiatives within telehealth for personalized care, treatment, and prevention. A broad, multinational research agenda can provide a uniform framework for identifying and rapidly replicating best practices, while concurrently fostering global collaboration in the development and rigorous testing of new and emerging telehealth technologies. In this paper, the members of the Transatlantic Telehealth Research Network offer a 12-point research agenda for future telehealth applications within chronic disease management.

Electricity use and economic development

International Nuclear Information System (INIS)

Ferguson, R.; Wilkinson, W.; Hill, R.

2000-01-01

A study of the relationship between electricity use and economic development in over one hundred countries, constituting over 99 per cent of the global economy has been undertaken. Correlations between electricity consumption/capita and GDP/capita have been analysed and compared with those between total primary energy supply/capita and GDP/capita. A supporting analysis has correlated the proportion of energy used in the form electricity, the 'e/E ratio', with GDP/capita. The general conclusions of this research are that wealthy countries have a stronger correlation between electricity use and wealth creation than do poor countries and that, for the global economy as a whole, there is a stronger correlation between electricity use and wealth creation than there is between total energy use and wealth. The study also shows that, in wealthy countries, the increase in wealth over time correlated with an increase in the e/E ratio. The results imply that the energy ratio (US dollars/toe) should be replace by the electricity ratio (US dollars/kWh) as a development indicator and, more precisely, by the e/E ratio (kWh/toe).

The current Ebola outbreak poses a threat to individual and global public health. Although the disease has been of interest to the scientific community since 1976, an effective vaccination approach is still lacking. This fact questions past global public health strategies, which have not foreseen the possible impact of this infectious disease. To quantify the global research activity in this field, a scientometric investigation was conducted. We analyzed the research output of countries, individual institutions and their collaborative networks. The resulting research architecture indicated that American and European countries played a leading role regarding output activity, citations and multi- and bilateral cooperations. When related to population numbers, African countries, which usually do not dominate the global research in other medical fields, were among the most prolific nations. We conclude that the field of Ebola research is constantly progressing, and the research landscape is influenced by economical and infrastructural factors as well as historical relations between countries and outbreak events.

Perspectives on the future of the electric utility industry

International Nuclear Information System (INIS)

Tonn, B.; Schaffhauser, A.

1994-04-01

This report offers perspectives on the future of the electric utility industry. These perspectives will be used in further research to assess the prospects for Integrated Resource Planning (IRP). The perspectives are developed first by examining economic, political and regulatory, societal, technological, and environmental trends that are (1) national and global in scope and (2) directly related to the electric utility industry. Major national and global trends include increasing global economic competition, increasing political and ethnic strife, rapidly changing technologies, and increasing worldwide concern about the environment. Major trends in the utility industry include increasing competition in generation; changing patterns of electricity demand; increasing use of information technology to control power systems; and increasing implementation of environmental controls. Ways in which the national and global trends may directly affect the utility industry are also explored. The trends are used to construct three global and national scenarios- ''business as usual,'' ''technotopia future,'' and ''fortress state'' -and three electric utility scenarios- ''frozen in headlights,'' ''megaelectric,'' and ''discomania.'' The scenarios are designed to be thought provoking descriptions of potential futures, not predictions of the future, although three key variables are identified that will have significant impacts on which future evolves-global climate change, utility technologies, and competition. While emphasis needs to be placed on understanding the electric utility scenarios, the interactions between the two sets of scenarios is also of interest

Royston, Geoff

2011-09-01

This paper considers how operational research and management science can improve the design of health systems and the delivery of health care, particularly in low-resource settings. It identifies some gaps in the way operational research is typically used in global health and proposes steps to bridge them. It then outlines some analytical tools of operational research and management science and illustrates how their use can inform some typical design and delivery challenges in global health. The paper concludes by considering factors that will increase and improve the contribution of operational research and management science to global health.

The politics of researching global health politics

Science.gov (United States)

Rushton, Simon

2015-01-01

In this comment, I build on Shiffman’s call for the global health community to more deeply investigate structural and productive power. I highlight two challenges we must grapple with as social scientists carrying out the types of investigation that Shiffman proposes: the politics of challenging the powerful; and the need to investigate types of expertise that have traditionally been thought of as ‘outside’ global health. In doing so, I argue that moving forward with the agenda Shiffman sets out requires social scientists interested in the global politics of health to be reflexive about our own exercise of structural and productive power and the fact that researching global health politics is itself a political undertaking.

Development of a global electricity supply model and investigation of electricity supply by renewable energies with a focus on energy storage requirements for Europe

Energy Technology Data Exchange (ETDEWEB)

Troendle, Tobias Wolfgang

2014-12-12

Electricity supply at present requires about 38% of the global primary energy demand and it is likely to rise further in the coming decades. Facing major problems, such as limited resources of fuels and an ongoing anthropogenic climate change, a sustainable electricity supply based on renewable energies is absolutely vital. Wind and solar power will play an extensive role in future supplies but require energy storage capacities to meet electricity demand. To investigate the relationship of power plant mix and required energy storage capacity, a computer model based on global weather data has been developed to enable the simulation of electricity supply scenarios by up to ten different power plant types for various regions. The focus of the investigation has been on the energy storage requirements of an electricity supply for Europe by wind and solar power. The minimum required energy storage capacity for a totally weather dependent electricity supply occurs at a ratio of 30% wind and 70% photovoltaic (PV) power plant capacity installed. Thus, the required energy storage capacity rises from a transition of to-day's electricity supply to the afore-mentioned 100% renewable wind and PV scenario exponentially to about 150 TWh (3.8% of the annual electricity demand). The installation of additional excess wind and PV power plant capacity was seen to be an efficient way to reduce the required energy storage. Already 10% excess capacity lead to a reduction by 50% of the required storage capacity. To use different storage technologies in an optimised way in terms of storage capacity and efficiency, the storage tasks can be separated into a daily and a seasonal usage. While the seasonal storage capacity has to be about two orders of magnitude larger than the required capacity of the storage for the daily cycle, the sum of stored energy during one year is almost equal for the long and short time storage. In summary, an electricity supply by wind and PV power was shown to

The Local Structure of Globalization. The Network Dynamics of Foreign Direct Investments in the International Electricity Industry

Science.gov (United States)

Koskinen, Johan; Lomi, Alessandro

2013-05-01

We study the evolution of the network of foreign direct investment (FDI) in the international electricity industry during the period 1994-2003. We assume that the ties in the network of investment relations between countries are created and deleted in continuous time, according to a conditional Gibbs distribution. This assumption allows us to take simultaneously into account the aggregate predictions of the well-established gravity model of international trade as well as local dependencies between network ties connecting the countries in our sample. According to the modified version of the gravity model that we specify, the probability of observing an investment tie between two countries depends on the mass of the economies involved, their physical distance, and the tendency of the network to self-organize into local configurations of network ties. While the limiting distribution of the data generating process is an exponential random graph model, we do not assume the system to be in equilibrium. We find evidence of the effects of the standard gravity model of international trade on evolution of the global FDI network. However, we also provide evidence of significant dyadic and extra-dyadic dependencies between investment ties that are typically ignored in available research. We show that local dependencies between national electricity industries are sufficient for explaining global properties of the network of foreign direct investments. We also show, however, that network dependencies vary significantly over time giving rise to a time-heterogeneous localized process of network evolution.

Climate impacts on hydropower and consequences for global electricity supply investment needs

Energy Technology Data Exchange (ETDEWEB)

Turner, Sean W. D.; Hejazi, Mohamad; Kim, Son H.; Clarke, Leon; Edmonds, Jae

2017-12-01

Recent progress in global scale hydrological and dam modeling has allowed for the study of climate change impacts on global hydropower production. Here we explore the possible consequences of these impacts for the electricity supply sector. Regional hydropower projections are developed for two emissions scenarios by forcing a coupled global hydrological and dam model with downscaled, bias-corrected climate realizations derived from sixteen general circulation models. Consequent impacts on power sector composition and associated emissions and investment costs are explored using the Global Change Assessment Model (GCAM). Changes in hydropower generation resulting from climate change can shift power demands onto and away from carbon intensive technologies, resulting in significant impacts on power sector CO2 emissions for certain world regions—primarily those located in Latin America, as well as Canada and parts of Europe. Reduced impacts of climate change on hydropower production under a low emissions scenario coincide with increased costs of marginal power generating capacity—meaning impacts on power sector investment costs are similar for high and low emissions scenarios. Individual countries where impacts on investment costs imply significant risks or opportunities are identified.

National inventory of Global Change relevant research in Norway; Nasjonal kartlegging av global change-relevant forskning

Energy Technology Data Exchange (ETDEWEB)

NONE

2001-05-01

The Norwegian Global Change Committee has made an inventory of global change research (GCR) projects funded by the Research Council of Norway (RCN) in 2001. In lack of a rigid definition, GCR was defined as research that can be considered relevant to the science agenda of the four major international global change programmes DIVERSITAS, IGBP, IHDP and WCRP. Relevance was judged based on the objectives stated for each of the international programmes and their core projects. It was not attempted to check whether the projects had any kind of link to the programmes they were considered relevant for. The grants provided by the RCN in 2001 to GCR as defined above amounts to about 77 mill. NOK. Based on a recent survey on climate change research it is reasonable to estimate that the RCN finances between 30 and 40 % of all GCR in Norway. Accordingly, the total value of Norwegian research relevant to the four international global change programmes in 2001 can be estimated to 192 - 254 mill. NOK.

The role of NGOs in global health research for development

Directory of Open Access Journals (Sweden)

Jones Lori

2005-02-01

Full Text Available Abstract Background Global health research is essential for development. A major issue is the inequitable distribution of research efforts and funds directed towards populations suffering the world's greatest health problems. This imbalance is fostering major attempts at redirecting research to the health problems of low and middle income countries. Following the creation of the Coalition for Global Health Research – Canada (CGHRC in 2001, the Canadian Society for International Health (CSIH decided to review the role of non-governmental organizations (NGOs in global health research. This paper highlights some of the prevalent thinking and is intended to encourage new thinking on how NGOs can further this role. Approach This paper was prepared by members of the Research Committee of the CSIH, with input from other members of the Society. Persons working in various international NGOs participated in individual interviews or group discussions on their involvement in different types of research activities. Case studies illustrate the roles of NGOs in global health research, their perceived strengths and weaknesses, and the constraints and opportunities to build capacity and develop partnerships for research. Highlights NGOs are contributing at all stages of the research cycle, fostering the relevance and effectiveness of the research, priority setting, and knowledge translation to action. They have a key role in stewardship (promoting and advocating for relevant global health research, resource mobilization for research, the generation, utilization and management of knowledge, and capacity development. Yet, typically, the involvement of NGOs in research is downstream from knowledge production and it usually takes the form of a partnership with universities or dedicated research agencies. Conclusion There is a need to more effectively include NGOs in all aspects of health research in order to maximize the potential benefits of research. NGOs

Essential competencies in global health research for medical trainees: A narrative review.

White, Mary T; Satterfield, Caley A; Blackard, Jason T

2017-09-01

Participation in short-term educational experiences in global health (STEGHs) among medical trainees is increasingly accompanied by interest in conducting research while abroad. Because formal training in both global health and research methods is currently under-represented in most medical curricula, trainees are often unfamiliar with the knowledge, attitudes, and skills necessary to design and conduct research successfully. This narrative review identifies essential global health research competencies for medical trainees engaged in STEGHs. The authors searched the literature using the terms global health, competency, research, research methods/process/training, scholarly project, medical student, and medical education/education. Because articles directly addressing global health research competencies for medical trainees were limited, the authors additionally drew on the broader literature addressing general research competencies and global health competencies. Articles yielded by the literature search, combined with established guidelines in research ethics and global health ethics, were used to identify six core domains and twenty discrete competencies fundamental to global health research at a level appropriate for medical trainees enrolled in STEGHs. Consideration was given to diverse research modalities, varying levels of training, and the availability of mentoring and on-site support. Research may provide important benefits to medical trainees and host partners. These competencies provide a starting point; however, circumstances at any host site may necessitate additional competencies specific to that setting. These competencies are also limited by the methodology employed in their development and the need for additional perspectives from host partners. The competencies identified outline basic knowledge, attitudes, and skills necessary for medical trainees to conduct limited global health research while participating in STEGHS. They may also be used as a

Researchers at NASA are investigating the potential for electric propulsion systems to revolutionize the design of aircraft from the small-scale general aviation sector to commuter and transport-class vehicles. Electric propulsion provides new degrees of design freedom that may enable opportunities for tightly coupled design and optimization of the propulsion system with the aircraft structure and control systems. This could lead to extraordinary reductions in ownership and operating costs, greenhouse gas emissions, and noise annoyance levels. We are building testbeds, high-fidelity aircraft simulations, and the first highly distributed electric inhabited flight test vehicle to begin to explore these opportunities.

Tobacco industry globalization and global health governance: towards an interdisciplinary research agenda

Lee, Kelley; Eckhardt, Jappe; Holden, Chris

2016-01-01

Shifting patterns of tobacco production and consumption, and the resultant disease burden worldwide since the late twentieth century, prompted efforts to strengthen global health governance through adoption of the Framework Convention on Tobacco Control. While the treaty is rightfully considered an important achievement, to address a neglected public health issue through collective action, evidence suggests that tobacco industry globalization continues apace. In this article, we provide a systematic review of the public health literature and reveal definitional and measurement imprecision, ahistorical timeframes, transnational tobacco companies and the state as the primary units and levels of analysis, and a strong emphasis on agency as opposed to structural power. Drawing on the study of globalization in international political economy and business studies, we identify opportunities to expand analysis along each of these dimensions. We conclude that this expanded and interdisciplinary research agenda provides the potential for fuller understanding of the dual and dynamic relationship between the tobacco industry and globalization. Deeper analysis of how the industry has adapted to globalization over time, as well as how the industry has influenced the nature and trajectory of globalization, is essential for building effective global governance responses. This article is published as part of a thematic collection dedicated to global governance. PMID:28458910

Aid alignment for global health research: the role of HIROs

Directory of Open Access Journals (Sweden)

Viergever Roderik F

2011-03-01

Full Text Available Abstract The lack of a mechanism that aligns financial flows for global health research towards public health priorities limits the impact of health research on health and health equity. Collaborative groups of health research funders appear to be particularly well situated to ameliorate this situation and to initiate discussion on aid alignment for global health research. One such group is the Heads of International Research Organizations (HIROs, which brings together a large number of major government and philanthropic funders of biomedical research. Surprisingly, there is hardly any information publicly available on HIROs' objectives, or on how it aims to achieve more harmonization in the field of research for health. Greater transparency on HIROs' objectives and on its current efforts towards addressing the gap between global health research needs and investments would be desirable, given the enormous potential benefits of more coordination by this group.

[Globalization in medical research].

Ehni, H-J; Wiesing, U

2018-03-01

The globalization of clinical research is gaining momentum. In particular, emerging countries, such as Brazil, India, Russia and South Africa show a significant increase in clinical trials. This trend is generating various ethical problems, which are examined in the present article. Sometimes, generally accepted ethical rules, such as the evaluation of clinical trials by ethics commissions are not respected and sometimes conflicts are generated which are difficult to resolve. For instance, it is controversial which standard of care researchers and sponsors have to provide in an international study. These conflicts are exacerbated by a fundamental dilemma: more research on diseases prevalent in developing and emerging countries is necessary. At the same time, the protection of study participants in those countries creates particular challenges. In recent years, international commissions and guidelines have achieved significant progress in solving these conflicts; however, the further development has to be analyzed very carefully. Incentives for better research on neglected diseases have to be created. Undesirable developments and abuse have to be prevented by appropriate international ethical standards.

'Electricity: The New Millennium' is a conference sponsored by four major industry associations -- Edison Electric Institute of the United States, the International Union of Producers of Electrical Energy in Europe, the Canadian Electricity Association and Japan's Federation of Electric Power Companies. The International Energy Agency and the host company, Hydro-Quebec, were also co-sponsors of this crucial and memorable event to provide company CEOs and other top executives of electric companies with opportunities to equip themselves with the facts and viewpoints essential to success in the restructured electrical business environment. The meeting and the accompanying exhibit took place in Montreal, Quebec, on June 18-21, 2000, and drew attendees and exhibitors from all over the world to discuss the radical changes that are affecting the industry in terms of the organization of production and delivery of electric power. Opportunities were also be provided to explore the challenges facing the industry on a global basis, including exploring ways to use emerging technologies for delivering the benefits of electric power to under-served regions of the world's population that has yet to enjoy the most basic quality of life improvements that electricity can afford. Critical issues sessions also explored issues such as building stronger customer relations, organizing and financing the industry's transition, mastering cultural change, the relationship between meeting society's goals and market forces, and transmission systems in transition. Commensurate with the vast range of topics, speakers and session leaders have been recruited from the ranks of chief executives of major energy companies from America to Zambia, government agencies, leaders of major power users, and industry associations.

For it was applied one matrix of sustainability indicators that considers the principles and criteria of general sustainability as 'not exhaustion of natural resources', 'non production of non degradable waste', and 'not high sensibility to social and environmental factors'. The approaches to evaluate in a wide way these principles are numerous and to each approach associates an indicator, call sustainability indicator. The contribution of this work consists on the development of a methodology to qualify globally the sustainability of each option of electric generation, combining all the sustainability indicators. The methodology applies a system of diffuse control to build the function of global qualification of sustainability dependent of all the indicators. (Author)

2018-03-01

With the rapid growth in the ownership of pure electric vehicles, the research on the valuation of used electric vehicles has become the key to the development of the pure electric used vehicle market. The paper analyzed the application of the three value assessment methods, current market price method, capitalized earning method and replacement cost method, in pure electric used vehicles, and draws a conclusion that the replacement cost method is more suitable for pure electric used car. At the same time, the article also conducted a parametric correction exploration research, aiming at the characteristics of pure electric vehicles and replacement cost of the constituent factors. Through the analysis of the applicability parameters of physical devaluation, functional devaluation and economic devaluation, the revised replacement cost method can be used for the valuation of purely used electric vehicles for private use.

Disclosure of electricity products--lessons from consumer research as guidance for energy policy

International Nuclear Information System (INIS)

Markard, Jochen; Holt, Edward

2003-01-01

In this article we compare recent findings from focus group research on electricity information disclosure in Switzerland with consumer research in the US. On the basis of the results, we provide an overview of disclosure schemes in the US and in Europe. Our aim is to summarize the key issues of electricity disclosure from a residential customer's point of view and to underline the potential of consumer research for energy policy making. The results are as follows: Consumer preferences for electricity disclosure are very similar in Switzerland and the US. There is a basic demand for trustworthy information and market transparency. Consumers want to compare electricity products with regard to price, generation sources, and environmental and contractual attributes. Thus, the disclosure of critical information is important to improve competition by increasing consumer confidence in their ability to choose among electricity offerings. Even more, electricity disclosure is a key element of consumer protection in general, and is a useful educational tool in regulated electricity markets

Pursuing Qualitative Research From the Global South: "Investigative Research" During China's "Great Leap Forward" (1958-62

Full Text Available Over the last decade, qualitative researchers have begun to challenge the domination and universalistic claims of the Global North. Nevertheless, it is still unclear what pursuing qualitative research (QR from the Global South might entail. I advance this effort by situating it in the larger context of the decentering endeavor in social science and decolonizing methodologies in aboriginal scholarship. Informed by their locally-grounded approach in the quest for constructing alternative social science accounts and articulating decolonized knowledge, I argue that writing locally-grounded histories is an essential first step to explore methodologies and epistemologies of QR from the Global South. Noting that no national history of QR has been derived from the Global South, I present an example of writing the history of QR by examining MAO Zedong's legacy of "investigative research" (IR. Specifically, I analyze the practices of IR during China's "Great Leap Forward" (1958-62. In conclusion, I discuss the implications of IR to the development of social science research in contemporary China. I lay out key issues in pursuing QR from the Global South and present how such a pursuit is relevant to social science inquiry in the Global North.

GETTING PERSONAL: ETHICS AND IDENTITY IN GLOBAL HEALTH RESEARCH

Science.gov (United States)

Simon, Christian; Mosavel, Maghboeba

2011-01-01

‘Researcher identity’ affects global health research in profound and complex ways. Anthropologists in particular have led the way in portraying the multiple, and sometimes tension-generating, identities that researchers ascribe to themselves, or have ascribed to them, in their places of research. However, the central importance of researcher identity in the ethical conduct of global health research has yet to be fully appreciated. The capacity of researchers to respond effectively to the ethical tensions surrounding their identities is hampered by lack of conceptual clarity, as to the nature and scope of the issues involved. This paper strives to provide some clarification of these ethical tensions by considering researcher identity from the perspective of (1) Guillemin and Heggen’s (2009) key distinction between procedural ethics and ethics in practice, and (2) our own distinction between perceptions of identity that are either symmetrical or asymmetrical, with the potential to shift research relationships toward greater or lesser ethical harmony. Discussion of these concepts is supported with ethnographic examples from relevant literature and from our own (United States (US) Government-funded) research in South Africa. A preliminary set of recommendations is provided in an effort to equip researchers with a greater sense of organization and control over the ethics of researcher identity. The paper concludes that the complex construction of researcher identity needs to be central among the ethical concerns of global health researchers, and that the conceptual tools discussed in the paper are a useful starting point for better organizing and acting on these ethical concerns.

Mentoring experiences and programmes are becoming increasingly recognised as important by those engaged in capacity strengthening in global health research. Using a primarily qualitative study design, we studied three experiences of mentorship and eight mentorship programmes for early career global health researchers based in high-income and low- and middle-income countries. For the latter, we drew upon programme materials, existing unpublished data and more formal mixed-method evaluations, supplemented by individual email questionnaire responses. Research team members wrote stories, and the team assembled and analysed them for key themes. Across the diverse experiences and programmes, key emergent themes included: great mentors inspire others in an inter-generational cascade, mentorship is transformative in personal and professional development and involves reciprocity, and finding the right balance in mentoring relationships and programmes includes responding creatively to failure. Among the challenges encountered were: struggling for more level playing fields for new health researchers globally, changing mindsets in institutions that do not have a culture of mentorship and building collaboration not competition. Mentoring networks spanning institutions and countries using multiple virtual and face-to-face methods are a potential avenue for fostering organisational cultures supporting quality mentorship in global health research.

The future political and economic relationships between industrial countries and between the industrial and developing countries will be influenced by the investments now being made for research and development (R and D). There is little public understanding of this $150 billion global investment, 25 percent of which is spent on military programs, 15 percent on basic research, and nearly 10 percent on space exploration, while the most-pressing world problems are receiving relatively little attention. A breakdown of geographic distribution of research and a comparison of government expenditures for different areas of R and D reveals a situation that could be corrected. National and corporate priorities need to be revised and political and institutional barriers must give way to new international and cooperative arrangements. 3 tables, 27 references. (DCK)

Global climate change: Social and economic research issues

International Nuclear Information System (INIS)

Rice, M.; Snow, J.; Jacobson, H.

1992-05-01

This workshop was designed to bring together a group of scholars, primarily from the social sciences, to explore research that might help in dealing with global climate change. To illustrate the state of present understanding, it seemed useful to focus this workshop on three broad questions that are involved in coping with climate change. These are: (1) How can the anticipated economic costs and benefits of climate change be identified; (2) How can the impacts of climate change be adjusted to or avoided; (3) What previously studied models are available for institutional management of the global environment? The resulting discussions may (1) identify worthwhile avenues for further social science research, (2) help develop feedback for natural scientists about research information from this domain needed by social scientists, and (3) provide policymakers with the sort of relevant research information from the social science community that is currently available

Authorship ethics in global health research partnerships between researchers from low or middle income countries and high income countries.

Science.gov (United States)

Smith, Elise; Hunt, Matthew; Master, Zubin

2014-05-28

Over the past two decades, the promotion of collaborative partnerships involving researchers from low and middle income countries with those from high income countries has been a major development in global health research. Ideally, these partnerships would lead to more equitable collaboration including the sharing of research responsibilities and rewards. While collaborative partnership initiatives have shown promise and attracted growing interest, there has been little scholarly debate regarding the fair distribution of authorship credit within these partnerships. In this paper, we identify four key authorship issues relevant to global health research and discuss their ethical and practical implications. First, we argue that authorship guidance may not adequately apply to global health research because it requires authors to write or substantially revise the manuscript. Since most journals of international reputation in global health are written in English, this would systematically and unjustly exclude non-English speaking researchers even if they have substantially contributed to the research project. Second, current guidance on authorship order does not address or mitigate unfair practices which can occur in global health research due to power differences between researchers from high and low-middle income countries. It also provides insufficient recognition of "technical tasks" such as local participant recruitment. Third, we consider the potential for real or perceived editorial bias in medical science journals in favour of prominent western researchers, and the risk of promoting misplaced credit and/or prestige authorship. Finally, we explore how diverse cultural practices and expectations regarding authorship may create conflict between researchers from low-middle and high income countries and contribute to unethical authorship practices. To effectively deal with these issues, we suggest: 1) undertaking further empirical and conceptual research regarding

The dynamics of technology diffusion and the impacts of climate policy instruments in the decarbonisation of the global electricity sector

This paper presents an analysis of climate policy instruments for the decarbonisation of the global electricity sector in a non-equilibrium economic and technology diffusion perspective. Energy markets are driven by innovation, path-dependent technology choices and diffusion. However, conventional optimisation models lack detail on these aspects and have limited ability to address the effectiveness of policy interventions because they do not represent decision-making. As a result, known effects of technology lock-ins are liable to be underestimated. In contrast, our approach places investor decision-making at the core of the analysis and investigates how it drives the diffusion of low-carbon technology in a highly disaggregated, hybrid, global macroeconometric model, FTT:Power-E3MG. Ten scenarios to 2050 of the electricity sector in 21 regions exploring combinations of electricity policy instruments are analysed, including their climate impacts. We show that in a diffusion and path-dependent perspective, the impact of combinations of policies does not correspond to the sum of impacts of individual instruments: synergies exist between policy tools. We argue that the carbon price required to break the current fossil technology lock-in can be much lower when combined with other policies, and that a 90% decarbonisation of the electricity sector by 2050 is affordable without early scrapping. - Highlights: • Policy scenarios for decarbonising of the global electricity sector by 90%. • Strong synergies exist between different energy policy instruments. • Carbon pricing not a sufficient policy instrument for large emissions reductions. • Improved agent behaviour assumptions for energy modelling beyond cost-optimisation

This is the final scientific/technical report for the Electric Power Infrastructure Reliability and Security R and D Initiative sponsored by the U.S. Department of Energy, Office of Electricity Delivery and Energy Reliability, under award number DE-FG02-05CH11292. This report covers results from the FSU-led, multi-institution effort conducted over the period 8/15/05 to 10/14/2007. Building upon existing infrastructure for power systems research, modeling, and simulation, the Center for Advanced Power Systems (CAPS) at Florida State University (FSU) is developing world-class programs in electric power systems research and education to support future electric power system needs and challenges. With U.S. Department of Energy Support, FSU CAPS has engaged in a multi-faceted effort to conduct basic and applied research towards understanding, developing, and deploying technologies and approaches that can lead to improved reliability and security of the North American electric power generation and delivery infrastructure. This wide-reaching project, through a number of carefully selected thrusts cutting across several research disciplines, set out to address key terrestrial electric utility power system issues and challenges. The challenges and the thrusts to address them were arrived at through analysis of a number of national reports and recommendations combined with input from an experienced multi-disciplined team of power systems research staff and faculty at FSU CAPS. The resulting project effort can be grouped into four major areas: - Power Systems and New Technology Insertion - Controls, Protection, and Security - Simulation Development - High Temperature Superconductivity (HTS)

Flexible mechanisms in the corporate greenhouse: implementation of the Kyoto Protocol and the globalization of the electric power industry

The contradictions and unresolved tensions between economic globalization and climate change negotiations have added urgency to the climate change debate. The paper argues that the declining role of the nation state in the global economy and the increasing reach of transnational corporations throughout the world present a serious challenge to the environmental integrity and success of international environmental treaties such as the Kyoto Protocol. In particular efficacy and equity of the flexible mechanism under the Kyoto Protocol are questioned as illustrated by the patterns of Foreign Direct Investment (FDI) of the US electric power industry in the developing world. US FDI in the electric power sectors of developing countries supports continued carbon-intensive development patterns which will make the long-term goals of the Kyoto Protocol more difficult to achieve. Consequently, FDI raises questions about justifiability of giving credit to Annex I countries through CDM projects undertaken by transnational electric power corporations. 13 refs.

Defining features of the practice of global health research: an examination of 14 global health research teams

Directory of Open Access Journals (Sweden)

Craig Stephen

2010-07-01

Full Text Available Objectives: This paper strives to develop a pragmatic view of the scope of practice and core characteristics of global health research (GHR by examining the activities of 14 Canadian-funded global health teams that were in the process of implementing research programs. Methods: Information was collected by a reflective exploration of team proposals and progress reports, a content analysis of the outputs from an all-team meeting and review of the literature. Results: Teams adopted equity-centered, problem-focused, systems-based approaches intended to find upstream determinants that could make people more resilient to social and ecological factors impacting their health. Long-term visions and time frames were needed to develop and solidify fully functional interdisciplinary, multinational, multicultural partnerships. The implementation of research into practice was a motivating factor for all teams, but to do this, they recognized the need for evidence-based advice on how to best do this. Traditional measures of biomedical research excellence were necessary but not sufficient to encompass views of excellence of team-based interdisciplinary research, which includes features like originality, coherence and cumulative contributions to fields of study, acceptance by peers and success in translating research into gains in health status. An innovative and nuanced approached to GHR ethics was needed to deal with some unique ethical issues because the needs for GHR were not adequately addressed by institutional biomedical research ethics boards. Core competencies for GHR researchers were a blend of those needed for health promotion, population health, international development, sustainable development, and systems science. Discussion: Developing acceptable and meaningful ways to evaluate the short-term contributions for GHR and forecast its long-term impacts is a strategic priority needed to defend decisions being made in GHR development.

Global oral health inequalities: the view from a research funder.

Garcia, I; Tabak, L A

2011-05-01

Despite impressive worldwide improvements in oral health, inequalities in oral health status among and within countries remain a daunting public health challenge. Oral health inequalities arise from a complex web of health determinants, including social, behavioral, economic, genetic, environmental, and health system factors. Eliminating these inequalities cannot be accomplished in isolation of oral health from overall health, or without recognizing that oral health is influenced at multiple individual, family, community, and health systems levels. For several reasons, this is an opportune time for global efforts targeted at reducing oral health inequalities. Global health is increasingly viewed not just as a humanitarian obligation, but also as a vehicle for health diplomacy and part of the broader mission to reduce poverty, build stronger economies, and strengthen global security. Despite the global economic recession, there are trends that portend well for support of global health efforts: increased globalization of research and development, growing investment from private philanthropy, an absolute growth of spending in research and innovation, and an enhanced interest in global health among young people. More systematic and far-reaching efforts will be required to address oral health inequalities through the engagement of oral health funders and sponsors of research, with partners from multiple public and private sectors. The oral health community must be "at the table" with other health disciplines and create opportunities for eliminating inequalities through collaborations that can harness both the intellectual and financial resources of multiple sectors and institutions.

While approaching the beginning of the twenty first century, the scientific community is faced with the formidable tasks of monitoring and detecting, understanding and predicting changes in the Earth System and its interactions with human beings. A crucial challenge is to make scientific research results accessible and usable for those involved in the decision making process related to the concept of Sustainable Development. Major international scientific programmes under the umbrella of ICSU, such as the IGBP and WCRP, are dealing with these issues. Although there exist many well developed global change research programmes in several European countries and effective collaboration networks between research institutes, there is an urgent need for overall communication with a view to promoting wider international links ensuring complementarity, synergy and coherence. Recognizing the importance of promoting coherence in research and utilising research results for various European Union (EU) policies, the European Commissioner responsible for Science, Research and Development wrote in March 1992 to all the EU Research Ministers to propose an initiative in this domain. In a rapid response, a group of Senior Experts from the EU Member States was set up in April 1992. This Group established a Task Force to develop the concept of the European Network for Research In Global CHange (ENRICH) which was approved in July 1993

Robustness of edge states in topological quantum dots against global electric field

Qu, Jin-Xian; Zhang, Shu-Hui; Liu, Ding-Yang; Wang, Ping; Yang, Wen

2017-07-01

The topological insulator has attracted increasing attention as a new state of quantum matter featured by the symmetry-protected edge states. Although the qualitative robustness of the edge states against local perturbations has been well established, it is not clear how these topological edge states respond quantitatively to a global perturbation. Here, we study the response of topological edge states in a HgTe quantum dot to an external in-plane electric field—a paradigmatic global perturbation in solid-state environments. We find that the stability of the topological edge state could be larger than that of the ground bulk state by several orders of magnitudes. This robustness may be verified by standard transport measurements in the Coulomb blockage regime. Our work may pave the way towards utilizing these topological edge states as stable memory devices for charge and/or spin information and stable emitter of single terahertz photons or entangled terahertz photon pairs for quantum communication.

Global solar energy radiation in relation with electricity supply in Romania

International Nuclear Information System (INIS)

Zoran, Maria

2001-01-01

Solar energy is one of the most viable source of renewable energy being both clean and nonpolluting. Spiraling energy use and other human activities have led to measurable effects upon the global environment and climatic changes. There is increasing international concern particularly in the areas of global warming owing to the increase of carbon dioxide (CO 2 ) in the atmosphere and of other greenhouse gases as sulfur dioxide (SO 2 ), oxides of nitrogen (NOx), hydrogen sulfide H 2 S, diethyl sulfide (DMS), chlorofluorocarbons (CFCs), methane CH 4 , as well in the effect of depletion of ozone (O 3 ) layer in the stratosphere. Climatological and global solar radiation analysis for some Romanian zones with great solar energy potential are presented. Remote sensing data provided by satellites are used for radiative fluxes monitoring and solar energy mapping as well as for solar energy use assessment. The realistic technical potential for solar energy applications in Romania is substantial, over 40000 TJyear -1 . As average energy global solar radiation in horizontal plane lies between 1100 and 1300 kWhm -2 year -1 , solar energy using for electrical power supply being a reliable alternative. More than one half of Romania's area has a range of insolation period between 1200 and 1500 hours year -1 , at an overall average daily irradiation of 1000 - 1200 kWh m -2 . The most favorable area in Romania is the North - Western part of Black Sea coast with an insolation period above 2300 hours year -1 . A small part 140 TJyear -1 are used profitably and almost 10% of the installed 10 6 m 2 of collector area, is still in operation. (author)

Investigations of radial electric field and global circulation layer in limiter tokamaks

International Nuclear Information System (INIS)

Zagorski, R.; Gerhauser, H.; Lehnen, M.; Loarer, T.

2002-01-01

An updated version of the 2D multifluid code TECXY is used to study the radial electric field structure and the appearance of a global circulation layer (GCL) inside the separatrix of the limiter tokamaks TEXTOR-94 and Tore-Supra-CIEL. The dependence of the driving forces on device geometry, limiter position, magnetic field orientation, impurity content and other parameters is investigated. The centrifugal force in the vicinity of the limiter head always determines the direction of the poloidal velocity in the GCL. There is good agreement with experimentally measured profiles of the poloidal velocity at the TEXTOR low field side. (orig.)

Cole, Donald C; Davison, Colleen; Hanson, Lori; Jackson, Suzanne F; Page, Ashley; Lencuch, Raphael; Kakuma, Ritz

2011-01-01

Different sets of competencies in public health, global health and research have recently emerged, including the Core Competencies for Public Health in Canada (CCPHC). Within this context, we believe it is important to articulate competencies for globalhealth practitioners-educators and researchers that are in addition to those outlined in the CCPHC. In global health, we require knowledge and skills regarding: north-south power dynamics, linkages between local and global health problems, and the roles of international organizations. We must be able to work responsibly in low-resource settings, foster self-determination in a world rife with power differentials, and engage in dialogue with stakeholders globally. Skills in cross-cultural communication and the ability to critically self-reflect on one's own social location within the global context are essential. Those in global health must be committed to improving health equity through global systems changes and be willing to be mentored and to mentor others across borders. We call for dialogue on these competencies and for development of ways to assess both their demonstration in academic settings and their performance in global health practice and research.

In this article, the main aspects that are considered important upon applying the ISO9000 standard [ISO 94] in a research institution, company, or group, are described. The 20 sections of the standard are discussed emphasizing the concepts and definitions that can be differently interpreted in the process of elaboration of a quality manual for a group devoted to research, than when they are applied in the elaboration of a manual for a factory that produces material goods. The exposed reasoning was used in the elaboration of the quality manual in the Information Systems Unit of the Electrical Research Institute in Mexico, and it is being used in the installation and operation of the quality system.

Global fate of POPs: Current and future research directions

International Nuclear Information System (INIS)

Lohmann, Rainer; Breivik, Knut; Dachs, Jordi; Muir, Derek

2007-01-01

For legacy and emerging persistent organic pollutants (POPs), surprisingly little is still known in quantitative terms about their global sources and emissions. Atmospheric transport has been identified as the key global dispersal mechanism for most legacy POPs. In contrast, transport by ocean currents may prove to be the main transport route for many polar, emerging POPs. This is linked to the POPs' intrinsic physico-chemical properties, as exemplified by the different fate of hexachlorocyclohexanes in the Arctic. Similarly, our current understanding of POPs' global transport and fate remains sketchy. The importance of organic carbon and global temperature differences have been accepted as key drivers of POPs' global distribution. However, future research will need to understand the various biogeochemical and geophysical cycles under anthropogenic pressures to be able to understand and predict the global fate of POPs accurately. - Future studies into the global fate of POPs will need to pay more attention to the various biogeochemical and anthropogenic cycles to better understand emissions, transport and sinks

Tuberculosis belongs to the lung infectious diseases with the highest impact on global burden of disease. Yet there is no concise scientometric study about tuberculosis research. Therefore, the NewQiS project elected this subject as focus of an in depth analysis to perform density equalizing mapping in combination with scientometrics. In this retrospective study all publications related to tuberculosis research listed in the Web of Science database between 1900 and 2012 were identified, analyzed and submitted to density equalizing mapping procedures. In total 58,319 entries on TBC were identified with the USA being the most productive country with 11,788 publications, followed by the United Kingdom (4202), India (3456), France (2541), South Africa (1840), Germany (1747) and China (1427). Concerning the citations rate Denmark leads with 43.7 citations per article, followed by Latvia (39.1), Gambia (38.3), Senegal (34.9), and the Netherlands (31.4). Chart techniques demonstrates a widely ramified international network with a focus the joint work of USA, the UK and South Africa. This is the first density equalizing and scientometric study that addresses tuberculosis research over a period of 112 years. It illustrates global tuberculosis research architecture and stresses the need for strengthening global research efforts and funding program. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Linking international research to global health equity: the limited contribution of bioethics.

Science.gov (United States)

Pratt, Bridget; Loff, Bebe

2013-05-01

Health research has been identified as a vehicle for advancing global justice in health. However, in bioethics, issues of global justice are mainly discussed within an ongoing debate on the conditions under which international clinical research is permissible. As a result, current ethical guidance predominantly links one type of international research (biomedical) to advancing one aspect of health equity (access to new treatments). International guidelines largely fail to connect international research to promoting broader aspects of health equity - namely, healthier social environments and stronger health systems. Bioethical frameworks such as the human development approach do consider how international clinical research is connected to the social determinants of health but, again, do so to address the question of when international clinical research is permissible. It is suggested that the narrow focus of this debate is shaped by high-income countries' economic strategies. The article further argues that the debate's focus obscures a stronger imperative to consider how other types of international research might advance justice in global health. Bioethics should consider the need for non-clinical health research and its contribution to advancing global justice. © 2011 Blackwell Publishing Ltd.

Decarbonization of electricity generation can support climate-change mitigation and presents an opportunity to address pollution resulting from fossil-fuel combustion. Generally, renewable technologies require higher initial investments in infrastructure than fossil-based power systems. To assess the tradeoffs of increased up-front emissions and reduced operational emissions, we present, to our knowledge, the first global, integrated life-cycle assessment (LCA) of long-term, wide-scale implementation of electricity generation from renewable sources (i.e., photovoltaic and solar thermal, wind, and hydropower) and of carbon dioxide capture and storage for fossil power generation. We compare emissions causing particulate matter exposure, freshwater ecotoxicity, freshwater eutrophication, and climate change for the climate-change-mitigation (BLUE Map) and business-as-usual (Baseline) scenarios of the International Energy Agency up to 2050. We use a vintage stock model to conduct an LCA of newly installed capacity year-by-year for each region, thus accounting for changes in the energy mix used to manufacture future power plants. Under the Baseline scenario, emissions of air and water pollutants more than double whereas the low-carbon technologies introduced in the BLUE Map scenario allow a doubling of electricity supply while stabilizing or even reducing pollution. Material requirements per unit generation for low-carbon technologies can be higher than for conventional fossil generation: 11-40 times more copper for photovoltaic systems and 6-14 times more iron for wind power plants. However, only two years of current global copper and one year of iron production will suffice to build a low-carbon energy system capable of supplying the world's electricity needs in 2050.

2017-09-01

The energy conservation of electric motor system is the key of industrial energy conservation. With the implementation and acceleration of electric motor energy efficiency improvement plan, more and more electric motors are knocked out. High-efficient remanufacturing of electric motor refers to improving the efficiency of electric motor and recycling the resources by replacing the winding, iron core and other components of electric motor on the basis of the low-efficient/outdated electric motors, which conforms to China’s policy of circular economy and resource recovery. The remanufacturing of electric motor not only maximizes the use of resources, but also reduces the energy consumption generated by reprocessing of cast iron, silicon steel sheet and other materials in dismantling of electric motor. However, structures and iron core materials used in design and manufacture of electric motors are different, and the degrees of wear of electric motors are also different under different operating conditions, which further result in diversified design schemes, increased remanufacturing cost and reduced remanufacturing efficiency. This paper analyzes the key process technologies for remanufacturing of electric motors are researched by analyzing the remanufacturing technologies of electric motors, and presents the feasibility to replace the cast-aluminum rotor with cast-copper rotor in high-efficient remanufacturing process of electric motor.

Vulnerabilities and opportunities at the nexus of electricity, water and climate

2015-01-01

The articles in this special issue examine the critical nexus of electricity, water, and climate, emphasizing connections among resources;  the prospect of increasing vulnerabilities of water resources and electricity generation in a changing climate;  and the opportunities for research to inform integrated energy and water policy and management measures aimed at reducing vulnerability and increasing resilience. Here, we characterize several major themes emerging from this research and highlight some of the uptake of this work in both scientific and public spheres.  Underpinning much of this research is the recognition that water resources are expected to undergo substantial changes based on the global warming that results primarily from fossil energy-based carbon emissions.  At the same time, the production of electricity from fossil fuels, nuclear power, and some renewable technologies (biomass, geothermal and concentrating solar power) can be highly water-intensive.  Energy choices now and in the near future will have a major impact not just on the global climate, but also on water supplies and the resilience of energy systems that currently depend heavily on them.

CERTS: Consortium for Electric Reliability Technology Solutions - Research Highlights

Energy Technology Data Exchange (ETDEWEB)

Eto, Joseph

2003-07-30

Historically, the U.S. electric power industry was vertically integrated, and utilities were responsible for system planning, operations, and reliability management. As the nation moves to a competitive market structure, these functions have been disaggregated, and no single entity is responsible for reliability management. As a result, new tools, technologies, systems, and management processes are needed to manage the reliability of the electricity grid. However, a number of simultaneous trends prevent electricity market participants from pursuing development of these reliability tools: utilities are preoccupied with restructuring their businesses, research funding has declined, and the formation of Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) to operate the grid means that control of transmission assets is separate from ownership of these assets; at the same time, business uncertainty, and changing regulatory policies have created a climate in which needed investment for transmission infrastructure and tools for reliability management has dried up. To address the resulting emerging gaps in reliability R&D, CERTS has undertaken much-needed public interest research on reliability technologies for the electricity grid. CERTS' vision is to: (1) Transform the electricity grid into an intelligent network that can sense and respond automatically to changing flows of power and emerging problems; (2) Enhance reliability management through market mechanisms, including transparency of real-time information on the status of the grid; (3) Empower customers to manage their energy use and reliability needs in response to real-time market price signals; and (4) Seamlessly integrate distributed technologies--including those for generation, storage, controls, and communications--to support the reliability needs of both the grid and individual customers.

Lucas, G.; Thayer, J. P.; Deierling, W.

2016-12-01

Kennedy Space Center (KSC) has operated an distributed array of over 30 electric field mills over the past 18 years, providing a unique data set of surface electric field measurements over a very long timespan. In addition to the electric field instruments there are many meteorological towers around KSC that monitor the local meteorological conditions. Utilizing these datasets we have investigated and found unique spatial and temporal signatures in the electric field data that are attributed to local meteorological effects and the global electric circuit. The local and global scale influences on the atmospheric electric field will be discussed including the generation of space charge from the ocean surf, local cloud cover, and a local enhancement in the electric field that is seen at sunrise.

From global bioethics to ethical governance of biomedical research collaborations.

One of the features of advanced life sciences research in recent years has been its internationalisation, with countries such as China and South Korea considered 'emerging biotech' locations. As a result, cross-continental collaborations are becoming common generating moves towards ethical and legal standardisation under the rubric of 'global bioethics'. Such a 'global', 'Western' or 'universal' bioethics has in turn been critiqued as an imposition upon resource-poor, non-Western or local medical settings. In this article, we propose that a different tack is necessary if we are to come to grips with the ethical challenges that inter-continental biomedical research collaborations generate. In particular we ask how national systems of ethical governance of life science research might cope with increasingly global research collaborations with a focus on Sino-European collaboration. We propose four 'spheres' - deliberation, regulation, oversight and interaction - as a helpful way to conceptualise national systems of ethical governance. Using a workshop-based mapping methodology (workshops held in Beijing, Shanghai, Changsha, Xian, Shenzen and London) we identified three specific ethical challenges arising from cross-continental research collaborations: (1) ambiguity as to which regulations are applicable; (2) lack of ethical review capacity not only among ethical review board members but also collaborating scientists; (3) already complex, researcher-research subject interaction is further complicated when many nationalities are involved.

Inequalities in global health inequalities research: A 50-year bibliometric analysis (1966-2015)

Science.gov (United States)

Pericàs, Juan M.; Benach, Joan

2018-01-01

Background Increasing evidence shows that health inequalities exist between and within countries, and emphasis has been placed on strengthening the production and use of the global health inequalities research, so as to improve capacities to act. Yet, a comprehensive overview of this evidence base is still needed, to determine what is known about the global and historical scientific production on health inequalities to date, how is it distributed in terms of country income groups and world regions, how has it changed over time, and what international collaboration dynamics exist. Methods A comprehensive bibliometric analysis of the global scientific production on health inequalities, from 1966 to 2015, was conducted using Scopus database. The historical and global evolution of the study of health inequalities was considered, and through joinpoint regression analysis and visualisation network maps, the preceding questions were examined. Findings 159 countries (via authorship affiliation) contributed to this scientific production, three times as many countries than previously found. Scientific output on health inequalities has exponentially grown over the last five decades, with several marked shift points, and a visible country-income group affiliation gradient in the initiation and consistent publication frequency. Higher income countries, especially Anglo-Saxon and European countries, disproportionately dominate first and co-authorship, and are at the core of the global collaborative research networks, with the Global South on the periphery. However, several country anomalies exist that suggest that the causes of these research inequalities, and potential underlying dependencies, run deeper than simply differences in country income and language. Conclusions Whilst the global evidence base has expanded, Global North-South research gaps exist, persist and, in some cases, are widening. Greater understanding of the structural determinants of these research

The Global Foot-and-mouth disease (FMD) Research Alliance periodically reviews the state of FMD research to assess progress and to identify new priorities. In this supplement we provide an update of global FMD research, comprising (i) this overview paper, which includes background information with key findings, and papers covering (ii) epidemiology, wildlife and economics, (iii) vaccines, (iv) diagnostics, (v) biotherapeutics and disinfectants, (vi) immunology and (vii) pathogenesis and molecular biology. FMD research publications were reviewed (2011-2015) and activity updates were obtained from 33 FMD research institutes from around the world. Although a continual threat, FMD has been effectively controlled in much of the world using existing tools. However, control remains a challenge in most developing countries, where little has been done to understand the ongoing burden of FMD. More research is needed to support control in endemically infected countries, particularly robust field studies. Traditional FMD vaccines have several limitations including short duration and spectrum of protection, cold chain requirements, and the costs and biosecurity risks associated with vaccine production. Significant progress has been made in the development of novel vaccine candidates, particularly in the use of recombinant vaccines and virus-like particles as an alternative to traditional inactivated whole virus vaccines. Continued investment is needed to turn these developments into improved vaccines produced at scale. Increased knowledge of cellular and mucosal immunity would benefit vaccine development, as would further advances in our ability to enhance vaccine capsid stability. Developments in molecular biology and phylogenetics underlie many of the recent advances in FMD research, including improved vaccines and diagnostics, and improved understanding of FMD epidemiology. Tools for genetic analyses continue to become both more powerful and more affordable enabling them to

Managing intermittent sources of electricity: the prospects opened by research

International Nuclear Information System (INIS)

Bigot, Bernard

2013-01-01

Beyond the difficult question of foreseeing the additional cost of placing one kWh of electricity on the grid - a cost that must be kept as low as possible to improve the technology for harnessing and converting energy - the growing share of electricity from renewable energy sources in national consumption (initially in replacement of fossil fuels) raises questions for research. How to limit the factors that make most of these forms of energy intermittent? One solution involves developing local or centralized storage capacities that are technically and economically efficient. Another proposal has to do with introducing information technology in electricity grids and electric appliances in order to reverse the currently prevailing rationale so that demand adjusts to supply, and not the reverse, in proportions that, though probably limited, are indispensable

The Centre for Global Health, Trinity College Dublin has as one of its goals, strengthening health systems in developing countries. In realising this goal we work across more than 40 countries with third-level, civil society, government, private sector and UN partners. Each of these requires that different relationships be established. Good principles must guide all global health research partnerships. An exploratory research project was undertaken with research partners of, and staff within, the Centre for Global Health. The aim was to build an evidence-based framework. An inductive exploratory research process was undertaken using a grounded theory approach in three consecutive phases: Phase I: An open-ended questionnaire was sent via email to all identified partners. Phase II: A series of consultative meetings were held with the staff of the Centre for Global Health. Phase III: Data sets from Phases I and II were applied to the development of a unifying framework. Data was analysed using grounded theory three stage thematic analysis - open, axial and selective coding. Relational and operational aspects of partnership were highlighted as being relevant across every partnership. Seven equally important core concepts emerged (focus, values, equity, benefit, leadership, communication and resolution), and are described and discussed here. Of these, two (leadership and resolution) are less often considered in existing literature on partnerships. Large complex partnerships can work well if all parties are agreed in advance to a common minimum programme, have been involved from the design stage, and have adequate resources specifically allocated. Based on this research, a framework for partnerships has been developed and is shared.

Towards an ethics safe harbor for global biomedical research

Science.gov (United States)

Dove, Edward S.; Knoppers, Bartha M.; Zawati, Ma'n H.

2014-01-01

Although increasingly global, data-driven genomics and other ‘omics’-focused research hold great promise for health discoveries, current research ethics review systems around the world challenge potential improvements in human health from such research. To overcome this challenge, we propose a ‘Safe Harbor Framework for International Ethics Equivalency’ that facilitates the harmonization of ethics review of specific types of data-driven international research projects while respecting globally transposable research ethics norms and principles. The Safe Harbor would consist in part of an agency supporting an International Federation for Ethics Review (IFER), formed by a voluntary compact among countries, granting agencies, philanthropies, institutions, and healthcare, patient advocacy, and research organizations. IFER would be both a central ethics review body, and also a forum for review and follow-up of policies concerning ethics norms for international research projects. It would be built on five principle elements: (1) registration, (2) compliance review, (3) recognition, (4) monitoring and enforcement, and (5) public participation. The Safe Harbor would create many benefits for researchers, countries, and the general public, and may eventually have application beyond (gen)omics to other areas of biomedical research that increasingly engage in secondary use of data and present only negligible risks.

Most people know that electric power lines, like the wiring in our homes, can cause serious electric shocks if we`re not careful. Many people also want to know whether the EMF (electric and magnetic fields) produced by power lines and other electrical devices affect our health. Although no adverse health effects of electric power EMF have been confirmed, there is continued scientific uncertainty about this issue. Research on EMF is ongoing throughout the world. The purpose of this booklet is to answer some common questions that the BPA (Bonneville Power Administration) receives about the possible effects of power lines on health. First, some basic electrical terms are defined, and electric and magnetic fields are debed. Next, answers are given to several questions about recent scientific studies. Some important information about electrical safety follows. We then describe how BPA is addressing public concerns about potential health effects of power lines. The last section tells you how to obtain more detailed information about the health and safety issues summarized in this booklet.

Applying a global justice lens to health systems research ethics: an initial exploration.

Recent scholarship has considered what, if anything, rich people owe to poor people to achieve justice in global health and the implications of this for international research. Yet this work has primarily focused on international clinical research. Health systems research is increasingly being performed in low and middle income countries and is essential to reducing global health disparities. This paper provides an initial description of the ethical issues related to priority setting, capacity-building, and the provision of post-study benefits that arise during the conduct of such research. It presents a selection of issues discussed in the health systems research literature and argues that they constitute ethical concerns based on their being inconsistent with a particular theory of global justice (the health capability paradigm). Issues identified include the fact that priority setting for health systems research at the global level is often not driven by national priorities and that capacity-building efforts frequently utilize one-size-fits-all approaches.

As the world's largest market for vehicles, China is facing challenges related to energy security and urban air pollution. The development of electric vehicles has been determined to be the national strategy for solving these problems. By the end of 2015, China had become the world's largest electric vehicles market, but its core technologies are still less competitive in the global marketplace. A scientific national strategy for 2016 to 2020 is expected to play a critical role in China becoming the global leader in the electric vehicle industry. The research process for this strategy includes a review of the technologies for electric vehicles, market analyses, benchmarking of the top levels in the field, and expert interviews. By these approaches, the strengths and weaknesses of China's electric vehicle technologies and industry are assessed. Competitive and feasible quantitative goals for key components and powertrains are proposed by this paper, and a core issue has been determined to be the need to improve the safety of high-energy density traction batteries. Improving the power density of electric control units is expected to the core for electric vehicles' electronics and control systems. Key problems for the fuel cell stacks used in cars and buses have been identified by this paper to be, respectively, power density and durability. Long-range plug-in hybrid electric powertrains are the optimal candidate for Chinese plug-in hybrid electric vehicles. Lightweight material, intelligent driving technologies and special electric chassis are set to be the focus for improving the energy efficiency of battery electric vehicles. Comprehensive safety and recyclable electric vehicle technologies are set to become key issues in the future, and the Chinese government should research and develop these in advance. - Highlights: • The key technologies of new energy vehicles are comprehensively reviewed. • The global technical status of key components is reviewed. �

2007-01-01

A LV electrical penetration assembly with perfusion sealing conductor feedthrough module was developed, which can be used for the connection of internal and external cables through the wall of the research reactor workshop. The LV electrical penetration assembly was combined with several independent modules. The maintenance and replacement of the assembly can be easily done in service. The sealing of conductor feedthrough module was achieved with the perfusion of self-extinguishing epoxy. The leakage between the conductor feedthrough module and the end plate module was blocked with rubber rings. The result of the leakage test and the electrical performance test for the samples of conductor feedthrough module satisfied the requirement of research reactor. The structure of the new electrical penetration assembly is simple and compact. It can be manufactured with mature technology and cost low price. The performance of the assembly is steady. It can be used widely in research reactors. (authors)

1989-01-01

The US Global Research Plan and the International Geosphere-Biosphere Programme were created to assess the effects of global climate change but have not been able to devote much attention to the consequences climate change will have on human health and welfare. Although researchers and policy makers recognize that climate change will have complex effects on resources, in general, the social and medical sciences have not received appropriate international attention under the banner of global change. To address this imbalance, the public health research community needs to launch a international coordinated effort so that the social and medical sciences are as fully represented as other scientific disciplines. This document discusses the information needs, research priorities and strategic considerations of the global change and its impact on human health.

Nuclear and global warming issues at a deregulated electricity market

International Nuclear Information System (INIS)

Mesarovic, M.

2001-01-01

The present challenge is to develop such an energy mix that best supports industrial and societal development and improves the quality of life, while simultaneously minimizing health and environmental impacts. Although two decades ago nuclear was considered to be the energy of the future, it is often overlooked in this context and is now even being questioned in many parts of the world. But, for a world facing increased energy demand and growing concerns about global warming due to the emissions of the 'greenhouse' gasses from burning fossil fuels, nuclear power may become the first priority again, since the nuclear power plants proved to be a reliable and safe source of electricity that produce no greenhouse or acid rain gases, and have already demonstrated their economic competitiveness with alternative generating sources of electrical energy. The competitiveness of nuclear power depends essentially on capital investments which must remain low enough to secure its competitive position. However, nuclear electricity in most countries is less competitive than coal and gas, particularly so after deregulation and liberalization of electricity markets have taken place. In the European Union (EU) there are at present 151 reactor blocks and 68 more in the rest of the European continent. Nuclear power plants in EU currently generate about 35% of electricity, but with the new competitive markets, a major decline in the use of coal is compensated for by an increase in gas because of its lower carbon content, and thus almost all new power stations fully or partially use gas as fuel. However, nuclear power is expected to remain a necessary component of the EU's energy mix for the next 20 years and beyond, and in Central and Eastern Europe it is continuing its growth. While Hungary recently gave up plans to construct two more blocks in its 'Pacs' plant, the Czech government agreed to continue construction of two blocks at its 'Temelin' plant. In Rumania, the second unit of

A globally nonsingular quaternion-based formulation for all-electric satellite trajectory optimization

Science.gov (United States)

Libraro, Paola

The general electric propulsion orbit-raising maneuver of a spacecraft must contend with four main limiting factors: the longer time of flight, multiple eclipses prohibiting continuous thrusting, long exposure to radiation from the Van Allen belt and high power requirement of the electric engines. In order to optimize a low-thrust transfer with respect to these challenges, the choice of coordinates and corresponding equations of motion used to describe the kinematical and dynamical behavior of the satellite is of critical importance. This choice can potentially affect the numerical optimization process as well as limit the set of mission scenarios that can be investigated. To increase the ability to determine the feasible set of mission scenarios able to address the challenges of an all-electric orbit-raising, a set of equations free of any singularities is required to consider a completely arbitrary injection orbit. For this purpose a new quaternion-based formulation of a spacecraft translational dynamics that is globally nonsingular has been developed. The minimum-time low-thrust problem has been solved using the new set of equations of motion inside a direct optimization scheme in order to investigate optimal low-thrust trajectories over the full range of injection orbit inclinations between 0 and 90 degrees with particular focus on high-inclinations. The numerical results consider a specific mission scenario in order to analyze three key aspects of the problem: the effect of the initial guess on the shape and duration of the transfer, the effect of Earth oblateness on transfer time and the role played by, radiation damage and power degradation in all-electric minimum-time transfers. Finally trade-offs between mass and cost savings are introduced through a test case.

Innovative financing for late-stage global health research and development: the Global Health Investment Fund.

Science.gov (United States)

Fitchett, Joseph Robert; Fan Li, Julia; Atun, Rifat

2016-01-01

Innovative financing strategies for global health are urgently needed to reinvigorate investment and new tools for impact. Bottleneck areas along the research and development (R&D) pipeline require particular attention, such as the transitions from preclinical discovery to clinical study, and product development to implementation and delivery. Successful organizations mobilizing and disbursing resources through innovating financing mechanisms include UNITAID, the Global Fund, and Gavi, the Vaccine Alliance. Although precise numbers are poorly documented, estimated investment in low-income settings falls seriously short of local need. This commentary discusses the newly established Global Health Investment Fund as a case study to support late-stage global health R&D. © The Author 2015.

1979-01-01

We have developed a new tool for ultrahigh-pressure research at LLL. This system, which we call the electric gun, has already achieved thin flyer plate velocities in excess of 20 km/s and pressures of the order of 2 TPa in tantalum. We believe that the electric gun is competitive with laser- and nuclear-driven methods of producing shocks in the 1-to-5 TPa range because of its precision and ease and economy of operation. Its development is recommended for shock initiation studies, dry runs for Site 300 hydroshots, and as a shock wave generator for surface studies

Inventory of Dutch National Research on Global Climate Change: Inside and outside the National Research Programme

International Nuclear Information System (INIS)

Smythe, K.D.; Bernabo, C.; Kingma, J.; Vrakking, W.

1993-04-01

This summary of Dutch research on global climate change was compiled from a survey of the major research organisations in the Netherlands. The scope and structure of the survey and this report were based on a request for information from the World Meteorological Organisation for an intergovernmental meeting on the World Climate Programme (WCP) held (from 14 to 16 April 1993). The WMO request emphasized activities related to the WCP and its associated programmes. To extend the usefulness of the exercise, an attempt has been made to broaden the focus to give additional attention to the Intergovernmental Geosphere-Biosphere Programme (IGBP) and the Human Dimensions Programme (HDP). This was the first attempt to inventory the research projects on global climate change underway in the Netherlands - both inside and outside the National Research Programme. Other surveys on Dutch climate-related research have been conducted. The most extensive effort was a cataloging of publications from climate research in the Netherlands from 1981 to 1991, which was conducted by the Netherlands Royal Academy of Sciences (KNAW). That inventory is being updated to include publications through 1992. The database resulting from this exercise will be a useful tool for organisations sponsoring and conducting global climate change research in their efforts to stimulate cooperation and promote coordination among research groups in the Netherlands and abroad. There are plans to update the inventory in the future and to provide the information to participating Dutch organisations as well as research organisations in other countries. An overview of the current research is provided in Volume 1 with a list of projects

Global warming: Towards a strategy for Ontario

International Nuclear Information System (INIS)

1990-01-01

A discussion paper is provided as background to a proposed public review of a strategy for Ontario's response to global warming. Global warming arises from the generation of greenhouse gases, which come from the use of fossil fuels, the use of chlorofluorocarbons, and deforestation. Energy policy is the backbone of achieving climate stability since the burning of fossil fuels releases most of the greenhouse gases, mainly carbon dioxide. Canada is, by international standards, a very energy-intensive country and is among the world's largest emitters of carbon dioxide on a per capita basis. Ontario is the largest energy-using province in Canada, and fossil fuels represent over 80% of provincial energy use. A proposed goal for Ontario is to provide leadership in stabilizing atmospheric concentrations of the greenhouse gases, while minimizing the social, economic, and environmental costs in Ontario of adapting to global warming. A proposed first step to address global warming is to achieve reductions in expected emissions of the greenhouse gases, especially carbon dioxide, so that levels by the year 2000 are lower than in 1989. Current policies and regulations helping to reduce the greenhouse effect include some of the current controls on automotive emissions and the adoption by the provincial electric utility of targets to reduce electricity demand. New initiatives include establishment of minimum energy efficiency standards and reduction of peak-day electricity use. Action steps for future consideration are detailed in the categories of greenhouse gas emissions reductions, carbon dioxide absorption, and research and analysis into global warming

Open Data in Global Environmental Research: Findings from the Community

Energy Technology Data Exchange (ETDEWEB)

Van Honk, J.; Calero-Medina, C.; Costas, R.

2016-07-01

This paper presents findings from the Belmont Forum’s survey on Open Data which targeted the global environmental research and data infrastructure community (Schmidt, Gemeinholzer & Treloar, 2016). It highlights users’ perceptions of the term “open data”, expectations of infrastructure functionalities, and barriers and enablers for the sharing of data. A wide range of good practice examples was pointed out by the respondents which demonstrates a substantial uptake of data sharing through e-infrastructures and a further need for enhancement and consolidation. Among all policy responses, funder policies seem to be the most important motivator. This supports the conclusion that stronger mandates will strengthen the case for data sharing. The Belmont Forum, a group of high-level representatives from major funding agencies across the globe, coordinates funding for collaborative research to address the challenges and opportunities of global environmental change. In particular, the E-Infrastructure and Data Management Collaborative Research Action has brought together domain scientists, computer and information scientists, legal scholars, social scientists, and other experts from more than 14 countries to establish recommendations on how the Belmont Forum can implement a more coordinated, holistic, and sustainable approach to the funding and support of global environmental change research.

Global implications of U.S. power deregulation

International Nuclear Information System (INIS)

Maschoff, D.C.

1996-01-01

With U.S. power deregulation remaining a topic that is dominating the entire North American energy marketplace, this paper provides an update of events occurring in U.S. electric power markets, offering some observations about changes due to increasing competition in electric power markets, and discusses some reasons why the events in U.S. electric power markets will soon transform global energy markets. How quickly is the move from local service territory to global markets proceeding? More than fifty U.S. utility companies with revenues of over $1 billion (U.S.) will soon be actively seeking and participating in global business opportunities. Using the same logic that led them to pursue utility initiatives nationally, U.S. utilities will use their core capabilities to compete in global energy services markets. In connection with these global initiatives, U.S. utilities will bring the same fuel-neutral, gas-electric perspective to international electric power and natural gas markets. (Author)

Research management at the Central Electricity Generating Board

International Nuclear Information System (INIS)

Broom, T.

1986-01-01

CEGB is responsible for power generation and transmission in England and Wales, and has a yearly production of some 230 TWh. There are three main fields of research: conventional generation and transmission, nuclear generation and environmental consequences of electricity generation. All laboratories carry out research in each field, though there are definite concentrations of specialities. The organisation of the research management changed emphasis in 1981 from an 'areal' (managing of individual institutes) to a topical approach (responsibilities for research fields). Good research requires good personnel, but also care on the part of the manager for the personal interests of the staff. There must be good cooperation between the researchers themselves, between researchers and managers, and between CEGB staff and researchers elsewhere. It is considered of prime importance that the researchers be true experts in their fields and that they maintain their scientific integrity. Other information is obtained by exchanging reports with comparable organisations, e.g. the KEMA in The Netherlands. Such an exchange requires mutual trust and research managers must therefore behave as true ambassadors. (Auth.)

Comparison of global storm activity rate calculated from Schumann resonance background components to electric field intensity E0 Z

2009-02-01

This work presents the results of a comparison between the global storm activity rate IRS and electric field intensity E0 Z. The permanent analysis of the IRS may become an important tool for testing Global Electric Circuit models. IRS is determined by a new method that uses the background component of the first 7 Schumann resonances (SR). The rate calculations are based on ELF observations carried out in 2005 and 2006 in the observatory station "Hylaty" of the Jagiellonian University in the Eastern Carpathians (Kułak, A., Zięba, S., Micek, S., Nieckarz, Z., 2003. Solar variations in extremely low frequency propagation parameters: I. A two-dimensional telegraph equation (TDTE) model of ELF propagation and fundamental parameters of Schumann resonances, J. Geophys. Res., 108, 1270, doi:10.1029/2002JA009304). Diurnal runs of the IRS rate were compared with diurnal runs of E0 Z amplitudes registered at the Earth's surface in the Geophysical Observatory of the Polish Academy of Sciences in Świder (Kubicki, M., 2005. Results of Atmospheric Electricity and Meteorological Observations, S. Kalinowski Geophysical Observatory at Świder 2004, Pub. Inst. Geophysics Polish Academy of Sciences, D-68 (383), Warszawa.). The days with the highest values of the correlation coefficient ( R) between amplitudes of both observed parameters characterizing atmosphere electric activity are shown. The seasonal changes of R, IRS and E0 Z are also presented.

GLOBEC: Global Ocean Ecosystems Dynamics: A component of the US Global Change Research Program

Science.gov (United States)

1991-01-01

GLOBEC (GLOBal ocean ECosystems dynamics) is a research initiative proposed by the oceanographic and fisheries communities to address the question of how changes in global environment are expected to affect the abundance and production of animals in the sea. The approach to this problem is to develop a fundamental understanding of the mechanisms that determine both the abundance of key marine animal populations and their variances in space and time. The assumption is that the physical environment is a major contributor to patterns of abundance and production of marine animals, in large part because the planktonic life stages typical of most marine animals are intrinsically at the mercy of the fluid motions of the medium in which they live. Consequently, the authors reason that a logical approach to predicting the potential impact of a globally changing environment is to understand how the physical environment, both directly and indirectly, contributes to animal abundance and its variability in marine ecosystems. The plans for this coordinated study of of the potential impact of global change on ocean ecosystems dynamics are discussed.

A TRMM/GPM retrieval of the total mean generator current for the global electric circuit

Science.gov (United States)

Peterson, Michael; Deierling, Wiebke; Liu, Chuntao; Mach, Douglas; Kalb, Christina

2017-09-01

A specialized satellite version of the passive microwave electric field retrieval algorithm (Peterson et al., 2015) is applied to observations from the Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) satellites to estimate the generator current for the Global Electric Circuit (GEC) and compute its temporal variability. By integrating retrieved Wilson currents from electrified clouds across the globe, we estimate a total mean current of between 1.4 kA (assuming the 7% fraction of electrified clouds producing downward currents measured by the ER-2 is representative) to 1.6 kA (assuming all electrified clouds contribute to the GEC). These current estimates come from all types of convective weather without preference, including Electrified Shower Clouds (ESCs). The diurnal distribution of the retrieved generator current is in excellent agreement with the Carnegie curve (RMS difference: 1.7%). The temporal variability of the total mean generator current ranges from 110% on semi-annual timescales (29% on an annual timescale) to 7.5% on decadal timescales with notable responses to the Madden-Julian Oscillation and El Nino Southern Oscillation. The geographical distribution of current includes significant contributions from oceanic regions in addition to the land-based tropical chimneys. The relative importance of the Americas and Asia chimneys compared to Africa is consistent with the best modern ground-based observations and further highlights the importance of ESCs for the GEC.

This report summarizes the hybrid electric concept design, analysis, and modeling work accomplished by the Boeing Subsonic Ultra Green Aircraft Research (SUGAR) team, consisting of Boeing Research and Technology, Boeing Commercial Airplanes, General Electric, and Georgia Tech.Performance and sizing tasks were conducted for hybrid electric versions of a conventional tube-and-wing aircraft and a hybrid wing body. The high wing Truss Braced Wing (TBW) SUGAR Volt was updated based on results from the TBW work (documented separately) and new engine performance models. Energy cost and acoustic analyses were conducted and technology roadmaps were updated for hybrid electric and battery technology. NOx emissions were calculated for landing and takeoff (LTO) and cruise. NPSS models were developed for hybrid electric components and tested using an integrated analysis of superconducting and non-superconducting hybrid electric engines. The hybrid electric SUGAR Volt was shown to produce significant emissions and fuel burn reductions beyond those achieved by the conventionally powered SUGAR High and was able to meet the NASA goals for fuel burn. Total energy utilization was not decreased but reduced energy cost can be achieved for some scenarios. The team was not able to identify a technology development path to meet NASA's noise goals

Romanian spatial planning research facing the challenges of globalizing sciences

Alexandru-Ionuţ Petrişor

Full Text Available There shouldn’t be any doubt that globalization not only affects economies, but also other areas of scholarly interest, such as the research environment. Within research, multi-disciplinary approaches are now being utilized on a grand scale. As a result, the joint evolution of scale and multi-disciplinarity seems to direct modern research from the ‘potholing’ towards the ‘sky-diving’ approach. In this context, many countries where the research tradition was affected by isolation are trying to catch up fast and compete within the global research ecosystem. However, some of the research domains have a longer tradition and developed their own rules, which are rapidly adopted by other fields, in order to equal the visibility of their predecessors. The positivist approach, consisting of statistically analyzing data resulting from experiments, which are, in turn, designed to test hypotheses derived from empirical observations or theoretical reasoning based on a literature review, has left an important fingerprint on current research practices. It also appears to be related to the pressure of publishing research, translated into the ‘publish or perish’ adage, and more recently, to the use of scientometric approaches to assess the value of articles, based on their citations. These new trends, along with an emerging competition between the scientometric giants, Thomson-Reuters and Scopus, facilitated the evolution of ‘predatory journals’, but also engendered a propensity towards designing hybrids between science and economy or between science and social networking. At the same time, the pressure resulted into individual unethical behaviors; some authors are no longer interested in delivering their results to the appropriate audience, but are looking instead for those means that could facilitate their academic or research promotion. Consequently, some journals are also attempting to meet these needs. The global race for research

GOING GLOBAL — ACTING LOCAL: SIEMENS IN THE CHINESE ELECTRICAL MARKET, 1904-1937

Directory of Open Access Journals (Sweden)

Mathias Mutz

2011-01-01

Full Text Available The German electrical manufacturer Siemens has been active in the Chinese market since the 1870s and established its first office in Shanghai in 1904. Focusing on marketing, the paper analyzes Siemens' business activities in China in the period from 1904 to 1937, and argues that the company exemplified a strategy of "glocalization," i.e. combining global business objectives and local adjustments. At the same time, the growing importance of international markets affected the development of the company as a whole. Referring to the contributions of "product," "price, "place" and "promotion" to the enterprise's development, this paper emphasizes the close connection between marketing and internationalization.

Governance of Transnational Global Health Research Consortia and Health Equity.

Science.gov (United States)

Pratt, Bridget; Hyder, Adnan A

2016-10-01

Global health research partnerships are increasingly taking the form of consortia of institutions from high-income countries and low- and middle-income countries that undertake programs of research. These partnerships differ from collaborations that carry out single projects in the multiplicity of their goals, scope of their activities, and nature of their management. Although such consortia typically aim to reduce health disparities between and within countries, what is required for them to do so has not been clearly defined. This article takes a conceptual approach to explore how the governance of transnational global health research consortia should be structured to advance health equity. To do so, it applies an account called shared health governance to derive procedural and substantive guidance. A checklist based on this guidance is proposed to assist research consortia determine where their governance practices strongly promote equity and where they may fall short.

Towards sustained Innovation in Education using Design-Based-Research - A new Approach to Teaching Electricity

CERN Multimedia

CERN. Geneva

2018-01-01

The influence of Physics Education Research (PER) on teaching in schools is often rather limited. Design-Based-Research tries to overcome this often-criticised research-practice gap by developing and evaluating new approaches to teaching physics. Using a variety of qualitative and quantitative research methods and working closely with schools, design research strives to find evidence-based solutions to pressing educational problems. One such problem in physics education is that most students fail to correctly analyse electric circuits even after instruction as they tend to reason exclusively with current and resistance. Effective reasoning about electric circuits, however, requires a solid understanding of voltage and potential. At the example of the development and evaluation of an innovative curriculum to teach electricity based on the electron gas model, the presentation will give an introduction to Design-Based-Research in PER.

The Human Factors Research Center was established within CRIEPI on July 1, 1987 as its research efforts to reduce human error during operation and maintenance at Japanese nuclear power plants. The Research Program has seven subjects, composed of the original subjects that include the human behavior monitoring method, and the subjects requested by the Federation of Electric Power Companies that include the establishment of techniques of analysing and evaluating information on human error. Some results of the activity are applied in nuclear power plants. We plan to obtain good results to apply to plants, and to improve the results already obtained. (author)

From Global to Local and Vice Versa: On the Importance of the 'Globalization' Agenda in Continental Groundwater Research and Policy-Making.

Science.gov (United States)

Filimonau, Viachaslau; Barth, Johannes A C

2016-09-01

Groundwater is one of the most important environmental resources and its use continuously rises globally for industrial, agricultural, and drinking water supply purposes. Because of its importance, more knowledge about the volume of usable groundwater is necessary to satisfy the global demand. Due to the challenges in quantifying the volume of available global groundwater, studies which aim to assess its magnitude are limited in number. They are further restricted in scope and depth of analysis as, in most cases, they do not explain how the estimates of global groundwater resources have been obtained, what methods have been used to generate the figures and what levels of uncertainty exist. This article reviews the estimates of global groundwater resources. It finds that the level of uncertainty attached to existing numbers often exceeds 100 % and strives to establish the reasons for discrepancy. The outcome of this study outlines the need for a new agenda in water research with a more pronounced focus on groundwater. This new research agenda should aim at enhancing the quality and quantity of data provision on local and regional groundwater stocks and flows. This knowledge enhancement can serve as a basis to improve policy-making on groundwater resources globally. Research-informed policies will facilitate more effective groundwater management practices to ensure a more rapid progress of the global water sector towards the goal of sustainability.

2013-12-01

Full Text Available globalization is changing the qualitative characteristics of society, affecting both the life and mentality of people. In relevance to globalization, higher education is gaining new dimensions as well. Bologna and Lisbon documents guide and obligate each country to create integrated and harmonious international space of higher education in Europe. phd studies are considered as integral in the higher education structure; therefore, internationalization is a significant imperative for phd studies development. In the process of internationalization, the need for students’ intercultural competencies is widely recognized. Firstly, we suppose that the impact of globalization on internationalization still remains underestimated. Globalization makes internationalization not only more intense, but also qualitatively different. Secondly, there is a lack of systemic analysis on the development of intercultural research competencies in phd studies. We relate the need for intercultural research competencies to the following critical and rhetorical question: ‘Are today’s phd students ready to solve tomorrow’s global problems?’

Conceptual framework for research on global change 1992-1995

International Nuclear Information System (INIS)

1992-04-01

For a better overall understanding of the Earth system scientists have initiated extensive international research programs dealing with the dynamics of the Earth system. These activities are characterized by their interdisciplinary, border crossing, and system orientated approach. For a long time scientists from the Federal Republic of Germany participate significantly in the conception and completion of such programs. The more and more urgent questions from politics and from the public have prompted the Federal Government under the leadership of the Federal Ministry for Research and Technology to increase these efforts. In this the Federal Government will also be supported by the Scientific Advisory Committee appointed by it, which annually presents a report on the state of global changes and their consequences. In this brochure the Conceptual Framework for Research on Global Changes is presented, which was passed by the Federal Cabinet in April 1992. It is documenting the advanced state of research, which has already been achieved in this country. At the same time, however, it is made clear that significant further steps have to be taken to contribute to the solution of the most urgent problems of the world. (orig.)

Inventory of Dutch National Research on Global Climate Change: Inside and outside the National Research Programme

International Nuclear Information System (INIS)

Smythe, K.D.; Bernabo, C.; Kingma, J.; Vrakking, W.

1993-04-01

This report contains brief descriptions of research projects in the field of global climate change, performed both within and outside the Dutch National Research Programme on Global Air Pollution and Climate Change (NRP). The descriptions result from a survey of the major research institutions in The Netherlands, conducted by two consultancies (Science and Policy Associates, SPA and Holland Consulting Group, HCG) at the request of the NRP. The inventory had to be completed within a relatively brief period; it is thus unavoidable that one or more projects may sometimes contain inaccuracies. Taken as a whole, this report presents a good picture of the Dutch research activities in this area. The scope and structure of this survey and the contents of this report are based on a request for information from the World Meteorological Organization (WMO) for an intergovernmental meeting on the World Climate Programme (WCP), held on 14-16 April 1993. The WMO request emphasised activities related to the WCP and its associated programmes. The database resulting from this exercise will be a useful tool for organisations which sponsor and conduct research into global climate change in their efforts to stimulate cooperation and to promote coordination between the research groups in The Netherlands and abroad. There are plans to update the inventory in the future and to provide the information to participating organisations in The Netherlands, as well as to research organisations in other countries. An overview of the current research is provided in Volume 1, a list of projects being provided in Annex 3. The projects are presented according to the themes and subthemes which are used in the NRP

Low-CO(2) electricity and hydrogen: a help or hindrance for electric and hydrogen vehicles?

Science.gov (United States)

Wallington, T J; Grahn, M; Anderson, J E; Mueller, S A; Williander, M I; Lindgren, K

2010-04-01

The title question was addressed using an energy model that accounts for projected global energy use in all sectors (transportation, heat, and power) of the global economy. Global CO(2) emissions were constrained to achieve stabilization at 400-550 ppm by 2100 at the lowest total system cost (equivalent to perfect CO(2) cap-and-trade regime). For future scenarios where vehicle technology costs were sufficiently competitive to advantage either hydrogen or electric vehicles, increased availability of low-cost, low-CO(2) electricity/hydrogen delayed (but did not prevent) the use of electric/hydrogen-powered vehicles in the model. This occurs when low-CO(2) electricity/hydrogen provides more cost-effective CO(2) mitigation opportunities in the heat and power energy sectors than in transportation. Connections between the sectors leading to this counterintuitive result need consideration in policy and technology planning.

International palliative care research in the context of global development: a systematic mapping review.

Science.gov (United States)

Clark, Joseph; Gardiner, Clare; Barnes, Amy

2018-03-01

An increasing amount of health policy is formulated at global level. At this global level, palliative care has attracted support primarily from normative institutions (WHO), not funding agencies. To attract greater global attention from policymakers, it has been argued that an international approach to research is required. However, the extent to which an international approach is being undertaken is unknown. To systematically identify and thematically synthesise all international palliative care research, defined as research involving two or more countries, or focused on the global level. Five bibliographic databases (CINAHL, Cochrane Library, ASSIA, Web of Knowledge, Psychinfo) were searched for journal articles relevant to international and global palliative care and end-of-life care. Data were extracted using a piloted extraction form and findings were synthesised. 184 studies were included, published across 75 different academic journals. Research emanates from and focuses on all world regions and there is increasing focus on the global level. Thematically, there is a high focus on Evaluation (n=53) and views of Stakeholders (n=38). The review revealed a predominantly observational research approach and few interventional studies were identified. International palliative care research is a relatively new, but growing field. However, many gaps in the evidence base remain and palliative care research continues to take place outside broader discourses of international development. The relative absence of interventional research demonstrating the effectiveness and cost-effectiveness of palliative care risks limiting the tools with which advocates can engage with international policymakers on this topic.

The Belmont Forum, a coalition of science funding agencies from 15 countries, is supporting an 18-month effort to assess the state of international of e-infrastructures and data management so that global change data and information can be more easily and efficiently exchanged internationally and across domains. Ultimately, this project aims to address the Belmont "Challenge" to deliver knowledge needed for action to avoid and adapt to detrimental environmental change, including extreme hazardous events. This effort emerged from conclusions by the Belmont Forum that transformative approaches and innovative technologies are needed for heterogeneous data/information to be integrated and made interoperable for researchers in disparate fields, and for myriad uses across international, institutional, disciplinary, spatial and temporal boundaries. The project will deliver a Community Strategy and Implementation Plan to prioritize international funding opportunities and long-term policy recommendations on how the Belmont Forum can implement a more coordinated, holistic, and sustainable approach to funding and supporting global change research. The Plan is expected to serve as the foundation of future Belmont Forum funding calls for proposals in support of research science goals as well as to establish long term e-infrastructure. More than 120 scientists, technologists, legal experts, social scientists, and other experts are participating in six Work Packages to develop the Plan by spring, 2015, under the broad rubrics of Architecture/Interoperability and Governance: Data Integration for Multidisciplinary Research; Improved Interface between Computation & Data Infrastructures; Harmonization of Global Data Infrastructure; Data Sharing; Open Data; and Capacity Building. Recommendations could lead to a more coordinated approach to policies, procedures and funding mechanisms to support e-infrastructures in a more sustainable way.

Global environmental security: Research and policy strategies for the 1990s

International Nuclear Information System (INIS)

Lazaro, M.A.; Wang, Hua.

1992-01-01

The subject of global environmental change is emerging as one of the most hotly debated international issues for the 1990s. In fact, our earth system has undergone a nature-induced gradual change in climate on both a temporal scale that spans over millions of years and a spatial scale ranging from regional to transcontinental. Pollutant emissions associated with population growth and industrial activities manifest the anthropogenic climatic forcing that has been superimposed on the background of natural climate fluctuations. Our incomplete understanding of the global impacts of environmental pollution on the earth systems (atmosphere, biosphere, hydrosphere, cryosphere, and lithosphere), however, make the prediction of the timing, magnitude, and patterns of future global change uncertain. This paper examines the science and policy background of global environmental change. The major scientific uncertainties and policy issues confronting decision makers are identified; and the scientific framework, as well as current national and international research programs aimed at resolving the scientific uncertainties, are discussed. A coherent, stable, and flexible policy is needed to provide a foundation for coordinated international-interagency programs of observation, research, analysis, and international negotiation toward a policy consensus concerning global environmental security. On the basis of what is currently known about global change, recommendations are presented on both near-term and long-term policy option decisions

2017-09-01

In this study, United States, China, India, United Kingdom, Nigeria, Egypt, Brazil, Italy, Germany, Taiwan, Australia, Canada and Mexico were selected to represent the global community. This enabled an overview of solid waste management worldwide and between developed and developing countries. These are countries that feature most in the International Conference on Solid Waste Technology and Management (ICSW) over the past 20 years. A total of 1452 articles directly on solid waste management and technology were reviewed and credited to their original country of research. Results show significant solid waste research potentials globally, with the United States leading by 373 articles, followed by India with 230 articles. The rest of the countries are ranked in the order of: UK > Taiwan > Brazil > Nigeria > Italy > Japan > China > Canada > Germany >Mexico > Egypt > Australia. Global capacity in solid waste management options is in the order of: Waste characterisation-management > waste biotech/composting > waste to landfill > waste recovery/reduction > waste in construction > waste recycling > waste treatment-reuse-storage > waste to energy > waste dumping > waste education/public participation/policy. It is observed that the solid waste research potential is not a measure of solid waste management capacity. The results show more significant research impacts on solid waste management in developed countries than in developing countries where economy, technology and society factors are not strong. This article is targeted to motivate similar study in each country, using solid waste research articles from other streamed databases to measure research impacts on solid waste management.

Research of Charging(Discharging Orderly and Optimizing Load Curve for Electric Vehicles Based on Dynamic Electric Price and V2G

Directory of Open Access Journals (Sweden)

Yang Shuai

2016-01-01

Full Text Available Firstly, using the Monte Carlo method and simulation analysis, this paper builds models for the behaviour of electric vehicles, the conventional charging model and the fast charging model. Secondly, this paper studies the impact that the number of electric vehicles which get access to power grid has on the daily load curve. Then, the paper put forwards a dynamic pricing mechanism of electricity, and studies how this dynamic pricing mechanism guides the electric vehicles to charge orderly. Last but not the least, the paper presents a V2G mechanism. Under this mechanism, electric vehicles can charge orderly and take part in the peak shaving. Research finds that massive electric vehicles’ access to the power grid will increase the peak-valley difference of daily load curve. Dynamic pricing mechanism and V2G mechanism can effectively lead the electric vehicles to take part in peak-shaving, and optimize the daily load curve.

Effect of global warming on willingness to pay for uninterrupted electricity supply in European nations

Science.gov (United States)

Cohen, Jed; Moeltner, Klaus; Reichl, Johannes; Schmidthaler, Michael

2018-01-01

Predicted changes in temperature and other weather events may damage the electricity grid and cause power outages. Understanding the costs of power outages and how these costs change over time with global warming can inform outage-mitigation-investment decisions. Here we show that across 19 EU nations the value of uninterrupted electricity supply is strongly related to local temperatures, and will increase as the climate warms. Bayesian hierarchical modelling of data from a choice experiment and respondent-specific temperature measures reveals estimates of willingness to pay (WTP) to avoid an hour of power outage between €0.32 and €1.86 per household. WTP varies on the basis of season and is heterogeneous between European nations. Winter outages currently cause larger per household welfare losses than summer outages per hour of outage. However, this dynamic will begin to shift under plausible future climates, with summer outages becoming substantially more costly and winter outages becoming slightly less costly on a per-household, per-hour basis.

Full Text Available Fault detection and isolation in a complex system are research hotspots and frontier problems in the reliability engineering field. Fault identification can be regarded as a procedure of excavating key characteristics from massive failure data, then classifying and identifying fault samples. In this paper, based on the fundamental of feature extraction about the fault coefficient, we will discuss the fault coefficient feature in complex electrical engineering in detail. For general fault types in a complex power system, even if there is a strong white Gaussian stochastic interference, the fault coefficient feature is still accurate and reliable. The results about comparative analysis of noise influence will also demonstrate the strong anti-interference ability and great redundancy of the fault coefficient feature in complex electrical engineering.

Terrestrial ecosystem responses to global change: A research strategy

Energy Technology Data Exchange (ETDEWEB)

NONE

1998-09-01

Uncertainty about the magnitude of global change effects on terrestrial ecosystems and consequent feedbacks to the atmosphere impedes sound policy planning at regional, national, and global scales. A strategy to reduce these uncertainties must include a substantial increase in funding for large-scale ecosystem experiments and a careful prioritization of research efforts. Prioritization criteria should be based on the magnitude of potential changes in environmental properties of concern to society, including productivity; biodiversity; the storage and cycling of carbon, water, and nutrients; and sensitivity of specific ecosystems to environmental change. A research strategy is proposed that builds on existing knowledge of ecosystem responses to global change by (1) expanding the spatial and temporal scale of experimental ecosystem manipulations to include processes known to occur at large scales and over long time periods; (2) quantifying poorly understood linkages among processes through the use of experiments that manipulate multiple interacting environmental factors over a broader range of relevant conditions than did past experiments; and (3) prioritizing ecosystems for major experimental manipulations on the basis of potential positive and negative impacts on ecosystem properties and processes of intrinsic and/or utilitarian value to humans and on feedbacks of terrestrial ecosystems to the atmosphere.

Sports, Global Politics, and Social Value Change: A Research Agenda

Directory of Open Access Journals (Sweden)

Lars Rensmann

2015-11-01

Full Text Available Despite their important role in forging, constructing and self-ascribing social identities and shaping popular culture, sports have long been a marginalized subject of social science inquiry, cultural studies, and research on international politics. Only in recent years this has begun to change. The article seeks to advance the still nascent but emerging cross-disciplinary field of research on sports and global politics in two ways: first, by addressing largely unexplored issues of sports, politics, and social conflicts, putting the spotlight on sociopolitical arenas beyond commercialized sports mega events, which have attracted most scholarly attention in contemporary research; and second, by generating hypotheses on the indirect political effects of sports cultures, in particular on the relationship between local social identities—reinforced through sports—and cosmopolitan value change. These interlinked spatial and substantive claims ground a new critical research framework and agenda: it examines sports as profoundly embedded in socioeconomic, cultural and political forms of rule and domination but also seeks to disclose sports’ emancipatory and subversive potential in advancing globalization from below.

In the last few decades, health systems research (HSR) has garnered much attention with a rapid increase in the related literature. This study aims to review and evaluate the global progress in HSR and assess the current quantitative trends. Based on data from the Web of Science database, scientometric methods and knowledge visualization techniques were applied to evaluate global scientific production and develop trends of HSR from 1900 to 2012. HSR has increased rapidly over the past 20 years. Currently, there are 28,787 research articles published in 3,674 journals that are listed in 140 Web of Science subject categories. The research in this field has mainly focused on public, environmental and occupational health (6,178, 21.46%), health care sciences and services (5,840, 20.29%), and general and internal medicine (3,783, 13.14%). The top 10 journals had published 2,969 (10.31%) articles and received 5,229 local citations and 40,271 global citations. The top 20 authors together contributed 628 papers, which accounted for a 2.18% share in the cumulative worldwide publications. The most productive author was McKee, from the London School of Hygiene & Tropical Medicine, with 48 articles. In addition, USA and American institutions ranked the first in health system research productivity, with high citation times, followed by the UK and Canada. HSR is an interdisciplinary area. Organization for Economic Co-operation and Development countries showed they are the leading nations in HSR. Meanwhile, American and Canadian institutions and the World Health Organization play a dominant role in the production, collaboration, and citation of high quality articles. Moreover, health policy and analysis research, health systems and sub-systems research, healthcare and services research, health, epidemiology and economics of communicable and non-communicable diseases, primary care research, health economics and health costs, and pharmacy of hospital have been identified as the

Potential global climate change

International Nuclear Information System (INIS)

Anon.

1994-01-01

Global economic integration and growth contribute much to the construction of energy plants, vehicles and other industrial products that produces carbon emission and in effect cause the destruction of the environment. A coordinated policy and response worldwide to curb emissions and to effect global climate change must be introduced. Improvement in scientific understanding is required to monitor how much emission reduction is necessary. In the near term, especially in the next seven years, sustained research and development for low carbon or carbon-free energy is necessary. Other measures must also be introduced, such as limiting the use of vehicles, closing down inefficient power plants, etc. In the long term, the use of the electric car, use solar energy, etc. is required. Reforestation must also be considered to absorb large amounts of carbon in the atmosphere

How are WEEE doing? A global review of the management of electrical and electronic wastes

International Nuclear Information System (INIS)

Ongondo, F.O.; Williams, I.D.; Cherrett, T.J.

2011-01-01

This paper presents and critically analyses the current waste electrical and electronic equipment (WEEE) management practices in various countries and regions. Global trends in (i) the quantities and composition of WEEE; and (ii) the various strategies and practices adopted by selected countries to handle, regulate and prevent WEEE are comprehensively examined. The findings indicate that for (i), the quantities of WEEE generated are high and/or on the increase. IT and telecommunications equipment seem to be the dominant WEEE being generated, at least in terms of numbers, in Africa, in the poorer regions of Asia and in Latin/South America. However, the paper contends that the reported figures on quantities of WEEE generated may be grossly underestimated. For (ii), with the notable exception of Europe, many countries seem to be lacking or are slow in initiating, drafting and adopting WEEE regulations. Handling of WEEE in developing countries is typified by high rate of repair and reuse within a largely informal recycling sector. In both developed and developing nations, the landfilling of WEEE is still a concern. It has been established that stockpiling of unwanted electrical and electronic products is common in both the USA and less developed economies. The paper also identifies and discusses four common priority areas for WEEE across the globe, namely: (i) resource depletion; (ii) ethical concerns; (iii) health and environmental issues; and (iv) WEEE takeback strategies. Further, the paper discusses the future perspectives on WEEE generation, treatment, prevention and regulation. Four key conclusions are drawn from this review: global amounts of WEEE will continue unabated for some time due to emergence of new technologies and affordable electronics; informal recycling in developing nations has the potential of making a valuable contribution if their operations can be changed with strict safety standards as a priority; the pace of initiating and enacting WEEE

Backed by a compelling foundation of essential requirements necessary for effective clinical trial conduct, and aided by initiatives that address concerns of data quality, regulatory timelines and IP protection, the clinical development sector in India has experienced annual revenue growth rates of 25% in the past two to three years, and is poised to participate substantially in global drug development. As both clinical trial sponsors and CROs increase their research capabilities in India, the clinical development sector is facing challenges with staff resourcing and facilities. Existing initiatives in the clinical sector must continue, and further investment must be made by stakeholders to overcome the current limitations in sector growth. Furthermore, global organizations seeking to derive long-term sustainable revenue growth and competitive advantage in the global marketplace from their business units in India must establish an appropriate organizational culture and an effective intra-organizational and industry interface for their operations.

Technical management of the reactor includes periodical maintenance as required by technical specifications, training, re-training and control of knowledge for reactor staff. During recent years, periodic preventive maintenance (PPM) has been carried out for the electric machines of the technological systems. (author)

Yours, Mine and Ours: Theorizing the Global Articulation of Qualitative Research Methods and Academic Disciplines

Directory of Open Access Journals (Sweden)

Bryan C. Taylor

2016-02-01

Full Text Available Two current forms of globalization are inherently interesting to academic qualitative researchers. The first is the globalization of qualitative research methods themselves. The second is the globalization of academic disciplines in which those methods are institutionalized as a valuable resource for professional practices of teaching and scholarly research. This essay argues that patterns in existing discussion of these two trends create an opportunity for innovative scholarship. That opportunity involves reflexively leveraging qualitative research methods to study the simultaneous negotiation by academic communities of both qualitative methods and their professional discipline. Five theories that serve to develop this opportunity are reviewed, focusing on their related benefits and limitations, and the specific research questions they yield. The essay concludes by synthesizing distinctive commitments of this proposed research program.

Culture, context and community: ethical considerations for global nursing research.

Harrowing, J N; Mill, J; Spiers, J; Kulig, J; Kipp, W

2010-03-01

High-quality research is essential for the generation of scientific nursing knowledge and the achievement of the Millennium Development Goals. However, the incorporation of Western bioethical principles in the study design may not be suitable, sufficient or relevant to participants in low-income countries and may indeed be harmful and disrespectful. Before engaging in global health studies, nurses must consider carefully the cultural and social context and values of the proposed setting in order to situate the research within the appropriate ethical framework. The purpose of this paper was to examine the ethical principles and considerations that guide health research conducted in international settings using the example of a qualitative study of Ugandan nurses and nurse-midwives by a Canadian researcher. The application of Western bioethical principles with their emphasis on autonomy fails to acknowledge the importance of relevant contextual aspects in the conduct of global research. Because ethics is concerned with how people interact and live together, it is essential that studies conducted across borders be respectful of, and congruent with, the values and needs of the community in which it occurs. The use of a communitarian ethical framework will allow nurse scientists to contribute to the elimination of inequities between those who enjoy prosperity and good health, and those who do not.

Academic Globalization And Ice: Cross-Cultural Research And Transnational Education

Full Text Available As the Lion said to the Man, "There are many statues of men slaying lions, but if only the lions were sculptors there might be quite a different set of statues." - Aesop Commensurate with Aesop's message of the sculptor matters, so does the communicator, the language and surprisingly, business context. The evolution from the experientially-based Cultureactive to the theoretically-based ICE, from first-generation to second-generation, this paper underscores the marriage of cross-cultural research and transnational education. Both Cultureactive and ICE serve at the pleasure of Globalization, and more importantly, Academic Globalization and Transnational Education. The impetus for this paper derives from two pivotal questions: Does one's professional lens create similarities more dominant than culture; and does English evoke responses significantly different from those of one's native language. ICE emerged from Cultureactive when validity and reliability research issues became noteworthy. Known as the ABC research team, Adair, Buchan and Chen [1] and [2] capitalized upon both Hall's low context/high context communication tool and Triandis' model of subjective culture to result in the theoretical underpinnings for ICE. This conceptual reconfiguration is also grounded in the works of Trompenaars, Holtgraves, Hampden-Turner, Thomas and Kilman, Yamagishi, and Bearden, Money and Nevins [3], [11], [20], [22] and [24]. ICE implementation strategies include the employment of Myers Briggs typologies. The contribution of this paper is the celebration of the first year of ICE [InterCultural Edge], and its far-reaching ramifications. Previous research streams have underscored global similarities and differences among cultures, and a previous paper [23] established that cross-professional rather than cross-cultural differences are more paramount in assessing communication differences. This study employs Cultureactive and the LMR model, noting that business

Demand response plays an important role in maintaining the economic stability of the system, and has the characteristics of high efficiency, low cost, fast response, good environmental benefits and so on. Demand side resource is an important part of electricity market. The research of demand side resources in our country is still in the initial stage, but the opening of the electricity sales side provides a broad prospect for the development of electricity market. This paper summarizes the main types of demand side resources in our country, analyzes the economic principle of demand response from the micro perspective, puts forward some suggestions on the operation mechanism of China’s demand side resources participating in the electricity market under the condition of electricity sales side opening, analyzes the current situation of pricing in the electricity wholesale market and sets up the pricing strategy of the centralized wholesale market with the demand side power supply participating in quotation, which makes the social and economic benefits reach the maximum.

Incursions from the epicentre: Southern theory, social science, and the global HIV research domain.

Science.gov (United States)

Hodes, Rebecca; Morrell, Robert

2018-03-01

Research about HIV constitutes a global domain of academic knowledge. The patterns that structure this domain reflect inequalities in the production and dissemination of knowledge, as well as broader inequalities in geopolitics. Conventional metrics for assessing the value and impact of academic research reveal that "Northern" research remains dominant, while "Southern" research remains peripheral. Southern theory provides a framework for greater critical engagement with knowledge produced by researchers within the global South. With a focus on HIV social science, we show that investigators working in and from Africa have produced and disseminated knowledge fundamental to the global domain of HIV research, and argue that their epistemological contribution may be understood within the framework of Southern theory. Through repurposing a bibliometrical measure of citation count, we constitute a new archive of highly cited social science research. With a focus on South Africa, we situate this archive within changing historical contexts, connecting research findings to developments in medicine, health sciences and politics. We focus on two key themes in the evolution of HIV knowledge: (1) the significance of context and locality - the "setting" of HIV research; and (2) sex, race and risk - changing ideas about the social determinants of HIV transmission.

Energy-Efficiency Policy Opportunities for Electric Motor-Driven Systems

Energy Technology Data Exchange (ETDEWEB)

NONE

2011-07-01

This publication is the first global analysis of energy consumption and energy efficiency potential of EMDS (electric motor- driven system). The electric motors and systems they drive are the largest single electricity end use, accounting for more than 40% of global electricity consumption. Huge energy efficiency potential was found untapped in EMDS - around 25% of EMDS electricity use could be saved cost-effectively, reducing total global electricity demand by about 10%. However, the energy efficiency of EMDS has been relatively neglected in comparison with other sustainable energy opportunities. It is crucial to scale up the operations and resources committed to realizing the vast savings potential of optimized EMDS. This paper proposes a comprehensive package of policy recommendations to help governments realize the potential for energy savings in EMDS.

Virtual CO2 Emission Flows in the Global Electricity Trade Network.

Quantifying greenhouse gas emissions due to electricity consumption is crucial for climate mitigation in the electric power sector. Current practices primarily use production-based emission factors to quantify emissions for electricity consumption, assuming production and consumption of electricity take place within the same region. The increasingly intensified cross-border electricity trade complicates the accounting for emissions of electricity consumption. This study employs a network approach to account for the flows in the whole electricity trade network to estimate CO 2 emissions of electricity consumption for 137 major countries/regions in 2014. Results show that in some countries, especially those in Europe and Southern Africa, the impacts of electricity trade on the estimation of emission factors and embodied emissions are significant. The changes made to emission factors by considering intergrid electricity trade can have significant implications for emission accounting and climate mitigation when multiplied by total electricity consumption of the corresponding countries/regions.

Nuclear plant aging research - an overview (electrical and mechanical components)

International Nuclear Information System (INIS)

Vora, J.P.

1985-01-01

As the operating nuclear power plants advance in age there must be a conscious national and international effort to understand the influence and safety implications of aging and service wear of components and structures in nuclear power plants and develop measures which are practical and cost effective for timely mitigation of aging degradation that could significantly affect plant safety. The Office of Nuclear Regulatory Research has, therefore, initiated a multi-year, multi-disciplinary program on Nuclear Plant Aging Research (NPAR). The overall goals identified for the program are as follows: 1) to identify and characterize aging and service wear effects associated with electrical and mechanical components, interfaces, and systems whose failure could impair plant safety; 2) to identify and recommend methods of inspection, surveillance and condition monitoring of electrical and mechanical components and systems which will be effective in detecting significant aging effects prior to loss of safety function so that timely maintenance and repair or replacement can be implemented; and, 3) to identify and recommend acceptable maintenance practices which can be undertaken to mitigate the effects of aging and to diminish the rate and extent of degradation caused by aging and service wear. The specific research activities to be implemented to achieve these goals are described

Scientists’ perspectives on global ocean research priorities

Murray Alan Rudd

2014-08-01

Full Text Available Diverse natural and social science research is needed to support policies to recover and sustain healthy oceans. While a wide variety of expert-led prioritization initiatives have identified research themes and priorities at national and regional scale, over the past several years there has also been a surge in the number of scanning exercises that have identified important environmental research questions and issues ‘from the bottom-up’. From those questions, winnowed from thousands of contributions by scientists and policy-makers around the world who participated in terrestrial, aquatic and domain-specific horizon scanning and big question exercises, I identified 657 research questions potentially important for informing decisions regarding ocean governance and sustainability. These were distilled to a short list of 67 distinctive research questions that, in an internet survey, were ranked by 2179 scientists from 94 countries. Five of the top 10 research priorities were shared by respondents globally. Despite significant differences between physical and ecological scientists’ priorities regarding specific research questions, they shared seven common priorities among their top 10. Social scientists’ priorities were, however, much different, highlighting their research focus on managerial solutions to ocean challenges and questions regarding the role of human behavior and values in attaining ocean sustainability. The results from this survey provide a comprehensive and timely assessment of current ocean research priorities among research-active scientists but highlight potential challenges in stimulating crossdisciplinary research. As ocean and coastal research necessarily becomes more transdisciplinary to address complex ocean challenges, it will be critical for scientists and research funders to understand how scientists from different disciplines and regions might collaborate and strengthen the overall evidence base for ocean

Thus, there is a need to provide an opportunity for the establishment of services which describe the rice information for better accessibility to information resources used by researchers to enhance the competitiveness. This work reviews some of available resources on rice bioinformatics and their roles in elucidating and propagating biological and genomic information in rice research. These reviews will also enable stakeholders to understand and adopt the change in research and development and share knowledge with the global community of agricultural scientists. The establishment like International Rice Information System, Rice Genome Research Project and Integrated Rice Genome Explorer are major initiatives for the improvement of rice. Creation of databases for comparative studies of rice and other cereals are major steps in further improvement of genetic compositions. This paper will also highlight some of the initiatives and organizations working in the field of rice improvement and explore the availability of the various web resources for the purpose of research and development of rice. We are developing a meta web server for integration of online resources such as databases, web servers and journals in the area of bioinformatics. This integrated platform, with acronym iBIRA, is available online at ibiranet.in. The resources reviewed here are the excerpts from the resources integrated in iBIRA.

The Perceptions of Globalization at a Public Research University Computer Science Graduate Department

Science.gov (United States)

Nielsen, Selin Yildiz

Based on a qualitative methodological approach, this study focuses on the understanding of a phenomenon called globalization in a research university computer science department. The study looks into the participants' perspectives about the department, its dynamics, culture and academic environment as related to globalization. The economic, political, academic and social/cultural aspects of the department are taken into consideration in investigating the influences of globalization. Three questions guide this inquiry: 1) How is the notion of globalization interpreted in this department? 2) How does the perception of globalization influence the department in terms of finances, academics, policies and social life And 3) How are these perceptions influence the selection of students? Globalization and neo-institutional view of legitimacy is used as theoretical lenses to conceptualize responses to these questions. The data include interviews, field notes, official and non-official documents. Interpretations of these data are compared to findings from prior research on the impact of globalization in order to clarify and validate findings. Findings show that there is disagreement in how the notion of globalization is interpreted between the doctoral students and the faculty in the department. This disagreement revealed the attitudes and interpretations of globalization in the light of the policies and procedures related to the department. How the faculty experience globalization is not consistent with the literature in this project. The literature states that globalization is a big part of higher education and it is a phenomenon that causes the changes in the goals and missions of higher education institutions (Knight, 2003, De Witt, 2005). The data revealed that globalization is not the cause for change but more of a consequence of actions that take place in achieving the goals and missions of the department.

Electric Power Research Institute's role in applying superconductivity to future utility systems

International Nuclear Information System (INIS)

Rabinowitz, M.

1975-01-01

Economics has been the single most important factor in determining the future of any new commercial technology in the United States. This criterion is in need of serious examination in view of the projected sharply increasing consumption of energy in the next few decades, particularly in the form of electricity. In order to make a smooth and meaningful transition from conventional methods of generating and transmitting electricity, a coordinated effort between all segments of the private and public domains will be required. The Electric Power Research Institute (EPRI) should play a vital role in planning for both the imminent short term, and long term national electrical energy needs; and in coordinating efforts to achieve these vital goals. If, as predicted, the U. S. power consumption increases by more than a factor of six in the next 30 years, it should be clear that it is necessary to develop high power density methods of producing and transmitting electricity. Superconductivity is the natural prime candidate for a new feasible technology that can take on this responsibility

The information and communication technology (ICT) sector continues to witness rapid growth and uptake of ICT equipment and services at both the national and global levels. The electricity consumption associated with this expansion is substantial, although recent adoptions of cloudcomputing services, co-location data centers, and other less energy-intensive equipment and operations have likely reduced the rate of growth in this sector. This paper is intended to aggregate existing ICT industry data and research to provide an initial look at electricity use, current and future renewable electricity acquisition, as well as serve as a benchmark for future growth and trends in ICT industry renewable electricity consumption.

Full Text Available The need to focus healthcare expenditures on innovative and sustainable health systems that efficiently use existing effective therapies are the major drivers stimulating Comparative Effectiveness Research (CER across the globe. Lack of adequate access and high cost of essential medicines and technologies in many countries increases morbidity and mortality and cost of care that forces people and families into poverty due to disability and out-of-pocket expenses. This review illustrates the potential of value-added global health care comparative effectiveness research in shaping health systems and health care delivery paradigms in the "global south". Enabling the development of effective CER systems globally paves the way for tangible local and regional definitions of equity in health care because CER fosters the sharing of critical assets, resources, skills, and capabilities and the development of collaborative of multi-sectorial frameworks to improve health outcomes and metrics globally.

Herbal medicine research and global health: an ethical analysis.

Science.gov (United States)

Tilburt, Jon C; Kaptchuk, Ted J

2008-08-01

Governments, international agencies and corporations are increasingly investing in traditional herbal medicine research. Yet little literature addresses ethical challenges in this research. In this paper, we apply concepts in a comprehensive ethical framework for clinical research to international traditional herbal medicine research. We examine in detail three key, underappreciated dimensions of the ethical framework in which particularly difficult questions arise for international herbal medicine research: social value, scientific validity and favourable risk-benefit ratio. Significant challenges exist in determining shared concepts of social value, scientific validity and favourable risk-benefit ratio across international research collaborations. However, we argue that collaborative partnership, including democratic deliberation, offers the context and process by which many of the ethical challenges in international herbal medicine research can, and should be, resolved. By "cross-training" investigators, and investing in safety-monitoring infrastructure, the issues identified by this comprehensive framework can promote ethically sound international herbal medicine research that contributes to global health.

Renewables 2013. Global Status Report

Renewable energy markets, industries, and policy frameworks have evolved rapidly in recent years. The Renewables Global Status Report provides a comprehensive and timely overview of renewable energy market, industry, investment, and policy developments worldwide. It relies on the most recent data available, provided by many contributors and researchers from around the world, all of which is brought together by a multi-disciplinary authoring team. The report covers recent developments, current status, and key trends; by design, it does not provide analysis or forecasts. This latest Renewables Global Status Report saw: a shift in investment patterns that led to a global decrease in clean energy investment; continuing growth in installed capacity due to significant technology cost reductions and increased investment in developing countries; renewables progressively supplementing established electricity systems, demonstrating that the implementation of suitable policies can enable the successful integration of higher shares of variable renewables; and the emergence of integrated policy approaches that link energy efficiency measures with the implementation of renewable energy technologies.

Bacterial meningitis is caused by a variety of pathogens and displays an important public health threat all over the world. Despite the necessity to develop customized public health-related research projects, a thorough study of global meningitis research is not present, so far. Therefore, the aim of this study was a combined density-equalizing and scientometric study. To evaluate the scientific efforts of bibliometric methods, density-equalizing algorithms and large-scale data analysis of the Web of Science were applied in the period between 1900 and 2007. From this, 7998 publications on bacterial meningitis have been found. With a number of 2698, most publications have been written by U.S. authors, followed by the UK (912), Germany (749) and France (620). This dominance can also be shown in the international cooperation. The specific citation analyses reveal that the nation with the highest average citation rate (citations per publications) was Norway (26.36), followed by Finland (24.16) and the U.S. (24.06). This study illustrates the architecture of global research on bacterial meningitis and points to the need for customized research programs with a focus on local public health issues in countries with a low development index, but high incidences, to target this global public health problem.

Access to reliable energy has been identified as a global priority and codified within United Nations Sustainable Goal 7 and the Electrify Africa Act of 2015. Reliable hospital access to electricity is necessary to provide safe surgical care. The current state of electrical availability in hospitals in low- and middle-income countries (LMICs) throughout the world is not well known. This study aimed to review the surgical capacity literature and document the availability of electricity and generators. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search for surgical capacity assessments in LMICs in MEDLINE, PubMed, and World Health Organization Global Health Library was performed. Data regarding electricity and generator availability were extracted. Estimated percentages for individual countries were calculated. Of 76 articles identified, 21 reported electricity availability, totaling 528 hospitals. Continuous electricity availability at hospitals providing surgical care was 312/528 (59.1%). Generator availability was 309/427 (72.4%). Estimated continuous electricity availability ranged from 0% (Sierra Leone and Malawi) to 100% (Iran); estimated generator availability was 14% (Somalia) to 97.6% (Iran). Less than two-thirds of hospitals providing surgical care in 21 LMICs have a continuous electricity source or have an available generator. Efforts are needed to improve electricity infrastructure at hospitals to assure safe surgical care. Future research should look at the effect of energy availability on surgical care and patient outcomes and novel methods of powering surgical equipment. Copyright © 2017 Elsevier Inc.

Challenge The lack of transparent, accessible, and centralized power sector data inhibits the ability to research the impact of the global power sector. information gaps for citizens, analysts, and decision makers worldwide create barriers to sustainable development efforts. The need for transparent, accessible, and centralized information is especially important to enhance the commitments outlined in the recently adopted Paris Agreement and Sustainable Development Goals. Offer Power Watch will address this challenge by creating a comprehensive, open-source platform on the world's power systems. The platform hosts data on 85% of global installed electrical capacity and for each power plant will include data points on installed capacity, fuel type, annual generation, commissioning year, with more characteristics like emissions, particulate matter, annual water demand and more added over time. Most of the data is reported from national level sources, but annual generation and other operational characteristiscs are estimated via Machine Learning modeling and remotely sensed data when not officially reported. In addition, Power Watch plans to provide a suite of tools that address specific decision maker needs, such as water risk assessments and air pollution modeling. Impact Through open data, the platform and its tools will allow reserachers to do more analysis of power sector impacts and perform energy modeling. It will help catalyze accountability for policy makers, businesses, and investors and will inform and drive the transition to a clean energy future while reaching development targets.

It has been broadly accepted worldwide that global warming, indeed, is the greatest threat of the time to the environment. Renewable energy (RE) is expected as a perfect solution to reduce global warming and to endorse sustainable development. Progressive release of greenhouse gases (GHG) from increasing energy-intensive industries has eventually caused human civilization to suffer. Realizing the exigency of reducing emissions and simultaneously catering to needs of industries, researchers foresee the RE as the perfect entrant to overcome these challenges. RE provides an effective option for the provision of energy services from the technical point of view while biomass, a major source of energy in the world until before industrialization when fossil fuels become dominant, appears an important renewable source of energy and researches have proven from time to time its viability for large-scale production. Being a widely spread source, biomass offers the execution of decentralized electricity generation gaining importance in liberalized electricity markets. The decentralized power is characterized by generation of electricity nearer to the demand centers, meeting the local energy needs. Researchers envisaged an increasing decentralization of power supply, expected to make a particular contribution to climate protection. This article investigates the progress and challenges for decentralized electricity generation by palm oil biomass according to the overall concept of sustainable development. (author)

Willingness to Pay for Renewable Electricity: A Review of Utility Market Research

Energy Technology Data Exchange (ETDEWEB)

Farhar, B. C.

1999-09-09

As competition in the electric utility industry has become more widespread and federal legislation deregulating the utility industry more likely, utilities have become more concerned about actions they can take to help ensure the loyalty of their customers. National polls have, for 20 years, found majority preferences for renewable energy over other energy sources. This issue brief compiles and analyzes recent market research conducted by utility companies on customer interest in and willingness to pay for renewable electricity. Findings in the areas examined in this review are: Customers are favorable toward renewable sources of electricity, although they know little about them; Solar and wind are the most favored sources of electricity generation; Majorities of 52% to nearly 100% of residential customers said they were willing to pay at least a modest amount more per month on their electric bills for green power; their responses follow a predictable curve showing that percentages willing to pay more decline as cost increases. The residential market for green pricing is approximately 2% near program rollout at a $5/month price increment, and should increase slowly but steadily over time; Customers may view with favor, and be more willing to purchase electricity from, utilities that provide green power.

Reducing Carbon Dioxide Emissions from Electricity Sector Using Smart Electric Grid Applications

Directory of Open Access Journals (Sweden)

Lamiaa Abdallah

2013-01-01

Full Text Available Approximately 40% of global CO2 emissions are emitted from electricity generation through the combustion of fossil fuels to generate heat needed to power steam turbines. Burning these fuels results in the production of carbon dioxide (CO2—the primary heat-trapping, “greenhouse gas” responsible for global warming. Applying smart electric grid technologies can potentially reduce CO2 emissions. Electric grid comprises three major sectors: generation, transmission and distribution grid, and consumption. Smart generation includes the use of renewable energy sources (wind, solar, or hydropower. Smart transmission and distribution relies on optimizing the existing assets of overhead transmission lines, underground cables, transformers, and substations such that minimum generating capacities are required in the future. Smart consumption will depend on the use of more efficient equipment like energy-saving lighting lamps, enabling smart homes and hybrid plug-in electric vehicles technologies. A special interest is given to the Egyptian case study. Main opportunities for Egypt include generating electricity from wind and solar energy sources and its geographical location that makes it a perfect center for interconnecting electrical systems from the Nile basin, North Africa, Gulf, and Europe. Challenges include shortage of investments, absence of political will, aging of transmission and distribution infrastructure, and lack of consumer awareness for power utilization.

How are WEEE doing? A global review of the management of electrical and electronic wastes.

Science.gov (United States)

Ongondo, F O; Williams, I D; Cherrett, T J

2011-04-01

This paper presents and critically analyses the current waste electrical and electronic equipment (WEEE) management practices in various countries and regions. Global trends in (i) the quantities and composition of WEEE; and (ii) the various strategies and practices adopted by selected countries to handle, regulate and prevent WEEE are comprehensively examined. The findings indicate that for (i), the quantities of WEEE generated are high and/or on the increase. IT and telecommunications equipment seem to be the dominant WEEE being generated, at least in terms of numbers, in Africa, in the poorer regions of Asia and in Latin/South America. However, the paper contends that the reported figures on quantities of WEEE generated may be grossly underestimated. For (ii), with the notable exception of Europe, many countries seem to be lacking or are slow in initiating, drafting and adopting WEEE regulations. Handling of WEEE in developing countries is typified by high rate of repair and reuse within a largely informal recycling sector. In both developed and developing nations, the landfilling of WEEE is still a concern. It has been established that stockpiling of unwanted electrical and electronic products is common in both the USA and less developed economies. The paper also identifies and discusses four common priority areas for WEEE across the globe, namely: (i) resource depletion; (ii) ethical concerns; (iii) health and environmental issues; and (iv) WEEE takeback strategies. Further, the paper discusses the future perspectives on WEEE generation, treatment, prevention and regulation. Four key conclusions are drawn from this review: global amounts of WEEE will continue unabated for some time due to emergence of new technologies and affordable electronics; informal recycling in developing nations has the potential of making a valuable contribution if their operations can be changed with strict safety standards as a priority; the pace of initiating and enacting WEEE

Globally, the majority of those who need mental health care worldwide lack access to high-quality mental health services. Stigma, human resource shortages, fragmented service delivery models, and lack of research capacity for implementation and policy change contribute to the current mental health treatment gap. In this review, we describe how health systems in low- and middle-income countries (LMICs) are addressing the mental health gap and further identify challenges and priority areas for future research. Common mental disorders are responsible for the largest proportion of the global burden of disease; yet, there is sound evidence that these disorders, as well as severe mental disorders, can be successfully treated using evidence-based interventions delivered by trained lay health workers in low-resource community or primary care settings. Stigma is a barrier to service uptake. Prevention, though necessary to address the mental health gap, has not solidified as a research or programmatic focus. Research-to-practice implementation studies are required to inform policies and scale-up services. Four priority areas are identified for focused attention to diminish the mental health treatment gap and to improve access to high-quality mental health services globally: diminishing pervasive stigma, building mental health system treatment and research capacity, implementing prevention programs to decrease the incidence of mental disorders, and establishing sustainable scale up of public health systems to improve access to mental health treatment using evidence-based interventions.

Fast Charging Electric Vehicle Research & Development Project

Energy Technology Data Exchange (ETDEWEB)

Heny, Michael

2014-03-31

The research and development project supported the engineering, design and implementation of on-road Electric Vehicle (“EV”) charging technologies. It included development of potential solutions for DC fast chargers (“DCFC”) capable of converting high voltage AC power to the DC power required by EVs. Additional development evaluated solutions related to the packaging of power electronic components and enclosure design, as well as for the design and evaluation of EV charging stations. Research compared different charging technologies to identify optimum applications in a municipal fleet. This project collected EV usage data and generated a report demonstrating that EVs, when supported by adequate charging infrastructure, are capable of replacing traditional internal combustion vehicles in many municipal applications. The project’s period of performance has demonstrated various methods of incorporating EVs into a municipal environment, and has identified three general categories for EV applications: Short Commute: Defined as EVs performing in limited duration, routine commutes. - Long Commute: Defined as tasks that require EVs to operate in longer daily mileage patterns. - Critical Needs: Defined as the need for EVs to be ready at every moment for indefinite periods. Together, the City of Charlottesville, VA (the “City”) and Aker Wade Power Technologies, LLC (“Aker Wade”) concluded that the EV has a viable position in many municipal fleets but with limited recommendation for use in Critical Needs applications such as Police fleets. The report also documented that, compared to internal combustion vehicles, BEVs have lower vehicle-related greenhouse gas (“GHG”) emissions and contribute to a reduction of air pollution in urban areas. The enhanced integration of EVs in a municipal fleet can result in reduced demand for imported oil and reduced municipal operating costs. The conclusions indicated in the project’s Engineering Report (see Attachment

International power supply policy and the globalisation of research: the example of fusion research

International Nuclear Information System (INIS)

Bechmann, G.; Gloede, F.; Lessmann, E.

2001-01-01

At the present state of our information, we can affirm that fusion research, as far as the necessary financial expenditures and their political justification are concerned, is a matter of politically controversial debate. In the political arenas, projects like controlled nuclear fusion are discussed primarily with regard to the controllability of complex technical systems and the sustainability of our future supply of electric power. The attempt to discuss this problem will have to consider: (i) on the one hand, already established concepts of sustainability; (ii) and on the other, the - according to the present state of our knowledge - foreseeable characteristics of a system of power generation and supply based on fusion reactors. Not only do the goals of global technology projects have to be embedded in patterns of universally accepted legitimisation (sustainability), but the organisation of research and development is also changing into networks acting globally. In this sense, globalisation means not only the worldwide linking of financial markets and the permanent availability of information and communication networks, but above all the creation of global organisations of research and innovation processes. The globalisation of research and development of technology has several dimensions: (i) the recognition and treatment of global problems; (ii) the transformation and evolution of new forms of organisation and cooperation in a global community of researchers; (iii) the constitution of Global Change Research. Fusion is playing a 'pathfinder role' for these processes and is at the same time itself an expression of the globalisation of the production of technology

The emerging competition on the electric power market is expected to be primarily used in the beginning by industrial or commercial customers. In Germany, households will also have free access to the competitive market right after deregulation of the market, so that private customers may likewise wish to exploit their chances and electric utilities should continue to consider the private households in their marketing concepts. The German electric power companies launched a variety of marketing research projects concentrating on the households. The article here analyses and explains the results.

A new electricity pricing theory is described that incorporates future uncertainty and intertemporal linkages between decisions. It indicates that electricity prices should contain two terms - short-run marginal cost plus a term that reflects how each particular decision is likely to affect future global welfare. A practical implementation using spot prices and forward contracts plus financial instruments for risk sharing and decision coordination is explored, and a procedure for developing long-term pricing policy is considered. The operation of industrial plant has been investigated and models developed to optimize plant behaviour in response to spot prices and forward contracts for electricity. These models are described and results of simulation studies discussed. The economic efficiency and risk sharing advantages of this advanced tariff structure compared with a conventional time-of-use tariff are illustrated.

Representations of the world enable global health research (GHR), discursively constructing sites in which studies can legitimately take place. Depoliticized portrayals of the global South frequently obscure messy legacies of colonialism and motivate technical responses to health problems with political and economic root causes. Such problematic representations of the world have not yet been rigorously examined in relation to global health ethics, a major site of scholarly effort towards GHR that promotes justice and fairness. We carried out a discourse analysis of four guidance documents relevant to the ethical practice of GHR, purposively selecting texts covering different genres (UN documents and journal articles) and prominent GHR foci (HIV and clinical trials). In light of increasing acknowledgement of the lessons Indigenous health scholarship holds for global health ethics, the four analyzed texts also included a set of principles developed to support Indigenous nation-building. Three of four documents featured global disparities as reasons for ethical caution. These inequalities appeared without explanation or causes, with generation of new scientific knowledge following as a logical response to such disparities. The fourth - Indigenous health-focused - document clearly identified 'colonialism' as a reason for both inequities in society, and related harmful research practices. Solutions to disparities in this text did not necessarily involve cutting-edge research, but focused instead on empowerment and responsiveness to community priorities and needs. These contrasting representations of the world were accomplished in ways that depended on texts' 'participants', or the people they represented; specific vocabularies or language usages; intertextual relationships to prior texts; and overall objectives or intentions of the author(s). Our results illustrate how ethics and other guidance documents serve as an important terrain for constructing, naturalizing or

Full Text Available A general-purpose Global Research Data Infrastructure (GRDI for all sciences and research purposes is not conceivable for the next decade as there are too many discipline-specific modalities that currently prevail for such generalisation efforts to be effective. On the other hand, a more pragmatic approach is to start from what currently exists, identify best practices and key issues, and promote effective inter-domain collaboration among different components forming an ecosystem. This will promote interoperability, data exchange, data preservation, and distributed access (among others. This ecosystem of interoperable research data infrastructures will be composed of regional, disciplinary, and multidisciplinary components, such as libraries, archives, and data centres, offering data services for both primary datasets and publications. The ecosystem will support data-intensive science and research and stimulate the interaction among all its elements, thus promoting multidisciplinary and interdisciplinary science. This special issue includes a set of independent papers from renowned experts on organisational and technological issues related to GRDIs. These documents feed into and compliment the GRDI2020 roadmap, which supports a Global Research Data Infrastructure ecosystem.

Is This the Only Hope for Reversing Global Warming? Transitioning Each Country's All-Purpose Energy to 100% Electricity Powered by Wind, Water, and Solar

Jacobson, M. Z.

2016-12-01

Global warming, air pollution, and energy insecurity are three of the most significant problems facing the world today. Can these problems be solved with existing technologies implemented on a large scale or do we need to wait for a miracle technology? This talk discusses the development of technical and economic plans to convert the energy infrastructure of each of 139 countries of the world to those powered by 100% wind, water, and sunlight (WWS) for all purposes using existing technology along with efficiency measures. All purposes includes electricity, transportation, heating/cooling, industry, and agriculture/forestry/fishing. The roadmaps propose using existing WWS generator technologies along with existing electrical transportation, heating/cooling, and industrial devices and appliances, plus existing electricity storage technologies, (CSP with storage, pumped hydroelectric storage, and existing hydroelectric power) and existing heat/cold storage technologies (water, ice, and rocks) for the transitions. They envision 80% conversion to WWS by 2030 and 100% by 2050. WWS not only replaces business-as-usual (BAU) power, but also reduces 2050 BAU demand due to the higher work to energy ratio of WWS electricity over combustion, the elimination of energy for mining, transporting, and processing fuels, and improvements in end-use efficiency beyond BAU. The study examines job creation versus loss, land use requirements, air pollution mortality and morbidity cost differences, and global warming cost differences due to the conversion in each country. Results suggest that implementing these roadmaps will stabilize energy prices because fuel costs are zero; reduce international conflict by creating energy-independent countries; reduce energy poverty; reduce power disruption by decentralizing power; and avoid exploding CO2 levels. Thus, the study concludes that a 100% WWS transition provides at least one solution to global warming Please see http

An Evolving Triadic World: A Theoretical Framework for Global Communication Research

Directory of Open Access Journals (Sweden)

Shelton A. Gunaratne

2015-08-01

Full Text Available A macro theory that recognizes the world’s three competing center-clusters and their respective hinterlands o?ers a realistic framework for global communication research. This study has used recent data on world trade, computers, Internet hosts, and high-tech exports to map the triadization of the world in the Information Age. The original dependency theory and world-system theory perspectives emphasized the hierarchical linking of national societies to the capitalist world-economy in a center-periphery structure. The proposed global-triadization formulation looks at the center-periphery structure in terms of a capitalist world-economy dominated by three competing center economic clusters, each of which has a dependent hinterland comprising peripheral economic clusters. These clusters may not necessarily be geographically contiguous. Strong-weak relationships may exist within each center-cluster, as well as within each periphery-cluster, with one center-cluster occupying a hegemonic role. The rudimentary Information-Society Power Index, constructed for this study, can guide the researcher to test an abundance of hypotheses on the pattern of global communication and information ?ow with particular attention to source, message, channel, and receiver.

Globalizing and crowdsourcing biomedical research.

Science.gov (United States)

Afshinnekoo, Ebrahim; Ahsanuddin, Sofia; Mason, Christopher E

2016-12-01

Crowdfunding and crowdsourcing of medical research has emerged as a novel paradigm for many biomedical disciplines to rapidly collect, process and interpret data from high-throughput and high-dimensional experiments. The novelty and promise of these approaches have led to fundamental discoveries about RNA mechanisms, microbiome dynamics and even patient interpretation of test results. However, these methods require robust training protocols, uniform sampling methods and experimental rigor in order to be useful for subsequent research efforts. Executed correctly, crowdfunding and crowdsourcing can leverage public resources and engagement to generate support for scientific endeavors that would otherwise be impossible due to funding constraints and or the large number of participants needed for data collection. We conducted a comprehensive literature review of scientific studies that utilized crowdsourcing and crowdfunding to generate data. We also discuss our own experiences conducting citizen-science research initiatives (MetaSUB and PathoMap) in ensuring data robustness, educational outreach and public engagement. We demonstrate the efficacy of crowdsourcing mechanisms for revolutionizing microbiome and metagenomic research to better elucidate the microbial and genetic dynamics of cities around the world (as well as non-urban areas). Crowdsourced studies have been able to create an improved and unprecedented ability to monitor, design and measure changes at the microbial and macroscopic scale. Thus, the use of crowdsourcing strategies has dramatically altered certain genomics research to create global citizen-science initiatives that reveal new discoveries about the world's genetic dynamics. The effectiveness of crowdfunding and crowdsourcing is largely dependent on the study design and methodology. One point of contention for the present discussion is the validity and scientific rigor of data that are generated by non-scientists. Selection bias, limited sample

Global healthcare practice has expanded in the past 20 years. At the same time the incorporation of research into the design process has gained prominence as a best practice among architects. The authors of this study investigated the status of design research in a variety of international settings. We intended to answer the question, "how pervasive is healthcare design research outside of the United States?" The authors reviewed the international literature on the design of healthcare facilities. More than 500 international studies and conference proceedings were incorporated in this literature review. A team of five research assistants searched multiple databases comparing approximately 16 keywords to geographic location. Some of those keywords included: evidence-based design, salutogenic design, design research, and healthcare environment. Additional articles were gathered by contacting prominent researchers and asking for their personal assessment of local health design research studies. While there are design researchers in most parts of the world, the majority of studies focus on the needs of populations in developed countries and generate guidelines that have significant cost and cultural implications that prohibit their implementation in developing countries. Additionally, the body of literature discussing the role of culture in healthcare environments is extremely limited. Design researchers must address the cultural implications of their studies. Additionally, we need to expand our research objectives to address healthcare design in countries that have not been previous considered. © 2014 Vendome Group, LLC.

Collaborative Development of e-Infrastructures and Data Management Practices for Global Change Research

Samors, R. J.; Allison, M. L.

2016-12-01

An e-infrastructure that supports data-intensive, multidisciplinary research is being organized under the auspices of the Belmont Forum consortium of national science funding agencies to accelerate the pace of science to address 21st century global change research challenges. The pace and breadth of change in information management across the data lifecycle means that no one country or institution can unilaterally provide the leadership and resources required to use data and information effectively, or needed to support a coordinated, global e-infrastructure. The five action themes adopted by the Belmont Forum: 1. Adopt and make enforceable Data Principles that establish a global, interoperable e-infrastructure. 2. Foster communication, collaboration and coordination between the wider research community and Belmont Forum and its projects through an e-Infrastructure Coordination, Communication, & Collaboration Office. 3. Promote effective data planning and stewardship in all Belmont Forum agency-funded research with a goal to make it enforceable. 4. Determine international and community best practice to inform Belmont Forum research e-infrastructure policy through identification and analysis of cross-disciplinary research case studies. 5. Support the development of a cross-disciplinary training curriculum to expand human capacity in technology and data-intensive analysis methods. The Belmont Forum is ideally poised to play a vital and transformative leadership role in establishing a sustained human and technical international data e-infrastructure to support global change research. In 2016, members of the 23-nation Belmont Forum began a collaborative implementation phase. Four multi-national teams are undertaking Action Themes based on the recommendations above. Tasks include mapping the landscape, identifying and documenting existing data management plans, and scheduling a series of workshops that analyse trans-disciplinary applications of existing Belmont Forum

Using Geothermal Electric Power to Reduce Carbon Footprint

Science.gov (United States)

Crombie, George W.

Human activities, including the burning of fossil fuels, increase carbon dioxide levels, which contributes to global warming. The research problem of the current study examined if geothermal electric power could adequately replace fossil fuel by 2050, thus reducing the emissions of carbon dioxide while avoiding potential problems with expanding nuclear generation. The purpose of this experimental research was to explore under what funding and business conditions geothermal power could be exploited to replace fossil fuels, chiefly coal. Complex systems theory, along with network theory, provided the theoretical foundation for the study. Research hypotheses focused on parameters, such as funding level, exploration type, and interfaces with the existing power grid that will bring the United States closest to the goal of phasing out fossil based power by 2050. The research was conducted by means of computer simulations, using agent-based modeling, wherein data were generated and analyzed. The simulations incorporated key information about the location of geothermal resources, exploitation methods, transmission grid limits and enhancements, and demand centers and growth. The simulation suggested that rapid and aggressive deployment of geothermal power plants in high potential areas, combined with a phase out of coal and nuclear plants, would produce minimal disruptions in the supply of electrical power in the United States. The implications for social change include reduced risk of global warming for all humans on the planet, reduced pollution due to reduction or elimination of coal and nuclear power, increased stability in energy supply and prices in the United States, and increased employment of United States citizens in jobs related to domestic energy production.

The globalization of health research: harnessing the scientific diaspora.

Anand, Nalini P; Hofman, Karen J; Glass, Roger I

2009-04-01

The scientific diaspora is a unique resource for U.S. universities. By drawing on the expertise, experience, and catalytic potential of diaspora scientists, universities can capitalize more fully on their diverse intellectual resources to make lasting contributions to global health. This article examines the unique contributions of the diaspora in international research collaborations, advantages of harnessing the diaspora and benefits to U.S. universities of fostering these collaborations, challenges faced by scientists who want to work with their home countries, examples of scientists engaging with their home countries, and specific strategies U.S. universities and donors can implement to catalyze these collaborations. The contributions of the diaspora to the United States are immense: International students enrolled in academic year 2007-2008 contributed an estimated $15 billion to the U.S. economy. As scientific research becomes increasingly global, the percentage of scientific publications with authors from foreign countries has grown from 8% in 1988 to 20% in 2005. Diaspora scientists can help build trusting relationships with scientists abroad, and international collaborations may improve the health of underserved populations at home. Although opportunities for diaspora networks are increasing, most home countries often lack enabling policies, infrastructure, and resources to effectively utilize their diaspora communities abroad. This article examines how some governments have successfully mobilized their scientific diaspora to become increasingly engaged in their national research agendas. Recommendations include specific strategies, including those that encourage U.S. universities to promote mini-sabbaticals and provide seed funding and flexible time frames.

A Universal Educational and Research Stand to Simulate Electrical Drive Loading

V. S. Grishin

2016-01-01

Full Text Available Universal educational and research stand was developed for analyzing an electrical drive’s behavior with different load disturbance effects. Major components of the stand are two electrical drives with rigidly coupled shafts. As a result, first electrical drive (loader has a capability to imitate effects of different loading types to another one (trial drive.Control software for the stand is developed. It allows us to combine a variety of loading types and change parameters of current loading such as joint moment, damping, additional inertia, and external torque. Also there is a capability to imitate effects of elasticity and backlash of mechanical transmissions. The paper considers the main challenge of creating the given system, i.e. discretization with a variable step. Some methods to decrease its negative effects on system stability are suggested.The given system allows to change loading parameters more rapidly and in a wider range as compared to a system with real mechanical outfit.These stands are currently used for laboratory classes within the course “Electrical robotic drives” at SM7 department in Bauman Moscow State Technical University. Also the system of interdepended stands for semi-realistic simulation of manipulation systems is under development.

The global energy industry: is competition among suppliers ensured?

International Nuclear Information System (INIS)

Regibeau, P.

2000-01-01

Over the last 15 years, many factors have affected the effective degree of competition in coal, electricity, gas and oil. This paper concentrates on the effects of globalization, regulatory reform, privatization and inter-fuel mergers. While demand side globalization has led to increased competition, greater supply side globalization might lead to more collusive behaviour in sectors such as coal and electricity. Regulatory reform has helped foster competition in the US gas market and in several electricity markets. Still, regulators have imposed insufficient vertical separation and the regulation of international electricity transmission remains problematic. Privatization is very useful in enforcing initial changes in industry structure. Inter-fuel mergers might entail efficiency gains but they also raise significant issues for competition policy authorities. (orig.)

Not so global: a bibliometric look at engineering education research

Williams, Bill; Wankat, Phillip C.; Neto, Pedro

2018-03-01

It has been suggested that Engineering Education Research (EER) is going global. If this were the case we would assume that the research of EER scholars in different parts of the globe would be informed by literature describing prior work within and beyond their home country/region. The authors set out to test this hypothesis by applying citation analysis to research presented in four publication venues: the annual conferences organised by ASEE (American Society of Engineering Education) and SEFI (European Society of Engineering Education) and two archival journals published by these two societies: Journal of Engineering Education (JEE) and European Journal of Engineering Education (EJEE). Our findings from the analysis of 4321 publications show that citations in ASEE conferences are dominated by sources with US affiliations, whereas the SEFI data show that while US sources are frequently cited, European and other authors are also well represented. With regard to the journals JEE and EJEE, a similar pattern is observed. These results suggest that, in citation terms, European EER is relatively global but US EER is not. The authors conclude by suggesting that if the EER community is to aspire to quality scholarship, there needs to be debate around how such issues can be tackled.

Power Deals. Mergers and acquisitions activity within the global electricity and gas market. 2010 Annual Review

Energy Technology Data Exchange (ETDEWEB)

NONE

2011-02-15

The global power deal market is finally seeing an upward trend in momentum from the lows reached in 2009, with the total deal value in the non-renewable electricity and gas sectors up 19% year on year from USD 97.6bn to USD 116bn in 2010 - a year which also saw an end to the deal stalemate in the US with a renewed deal flow that looks set to continue this year. Compared to the heady mountain of power deals transacted between 2005-2008, deal values remain low but conditions are in place for a return at least to the foothills of these peaks, according to PwC's annual Power Deals review. Globalisation of the power sector is moving forward on a number of fronts with, for example, companies looking at gaining a larger presence in growth markets, acquisitions of global network asset portfolios with strong international interest in infrastructure assets and signs of greater Chinese involvement, not just from grid companies but also independent power producers.

Electric Field Encephalography as a tool for functional brain research: a modeling study.

Directory of Open Access Journals (Sweden)

Yury Petrov

Full Text Available We introduce the notion of Electric Field Encephalography (EFEG based on measuring electric fields of the brain and demonstrate, using computer modeling, that given the appropriate electric field sensors this technique may have significant advantages over the current EEG technique. Unlike EEG, EFEG can be used to measure brain activity in a contactless and reference-free manner at significant distances from the head surface. Principal component analysis using simulated cortical sources demonstrated that electric field sensors positioned 3 cm away from the scalp and characterized by the same signal-to-noise ratio as EEG sensors provided the same number of uncorrelated signals as scalp EEG. When positioned on the scalp, EFEG sensors provided 2-3 times more uncorrelated signals. This significant increase in the number of uncorrelated signals can be used for more accurate assessment of brain states for non-invasive brain-computer interfaces and neurofeedback applications. It also may lead to major improvements in source localization precision. Source localization simulations for the spherical and Boundary Element Method (BEM head models demonstrated that the localization errors are reduced two-fold when using electric fields instead of electric potentials. We have identified several techniques that could be adapted for the measurement of the electric field vector required for EFEG and anticipate that this study will stimulate new experimental approaches to utilize this new tool for functional brain research.

Highlights: • We assess the performance of 4 buses that run on different alternative fuel types and technologies. • The buses assessed are Fuel Cell-Hybrid Bus, Hybrid Diesel-Electric Bus, Battery Electric Bus, and a Diesel Bus. • We examine the environmental impact caused by the Life Cycle of each vehicle technology, fossil fuel and energy carrier. • Life Cycle of Battery Electric Bus shows that it has a big potential of improvement in terms of environmental impact. - Abstract: In spite of the advanced research in automotive technology, and the improvement of fuels, the road transport sector continues to be an environmental concern, since the increase in transport demand is offsetting the effects of these technological improvements. Therefore, this poses the following question: what combination of technology and fuel is more efficient in terms of energy consumption and green house gas (GHG) emissions? To fully address this question it is necessary to carry out a Life Cycle Assessment (LCA). This paper presents a global LCA of 4 buses that run on the following fuel types and technologies: (1) Fuel Cell- Hybrid Bus, (2) Hybrid Diesel-Electric Bus (series configuration), (3) Battery Electric Bus and (4) Combustion Ignition Engine Bus. The impact categories assessed are: primary energy consumption, fossil energy and GHG emissions. Among the principal results, we can conclude that the Global LCA of buses (3) and (1) (which are the more sensitive pathways to the electricity mix variation) have for the 2008–2030 period a room for improvement of 25.62% and 28.16% in terms of efficiency of fossil energy consumption and a potential GHG emission reduction of 28.70% and 30.88% respectively

A survey of critical research areas in the energy segment of restructured electric power markets

Nanduri, Vishnu; Das, Tapas K.

2009-01-01

Availability of a large volume of recent literature on deregulated (a.k.a. restructured) electricity markets underscores the importance of the research needs to ensure proper design and functioning of the markets. Researchers have made significant contributions fueling the evolution of the fundamental market design changes that have taken place since the beginning of the restructuring process. Due to the vast scope, existing survey papers are focused on particular facets of deregulated electricity markets. We adopt a similar approach by focusing on the most important research areas related to the energy market. The contributions of the survey paper lie in the novel approach used in classifying the literature based on critical research areas. Some areas of research such as auction based pricing, bidding strategy formulation, market equilibria, and market power are reviewed in a different light than other existing survey papers. We conclude by providing some future research directions for the energy markets. (author)

Li Jiangang; Zhang Jie; Duan Xuru

2010-01-01

Energy shortage and environmental pollution are two critical issues for human beings in the 21st century. There is an urgent need for new sustainable energy to meet the fast growing demand for clean energy. Fusion is one of the few options which may be able to satisfy the requirement for large scale sustainable energy generation and global warming suppression and therefore must be developed as quickly as possible. Fusion research has been carried out for the past 50 years. It is too long to wait for another 50 years to generate electricity by fusion. A much more aggressive approach should be taken with international collaboration towards the early use of fusion energy to meet the urgent needs for energy and global warming suppression.

Global climate-oriented building energy use scenarios

International Nuclear Information System (INIS)

Harvey, L.D. Danny

2014-01-01

This paper explores the extent to which global fuel use in buildings could be reduced, and the growth in global electricity use in buildings limited, by applying stringent (factor of 3–4) improvements to recent building codes for new buildings worldwide and large (factor of 2–3) reductions in the energy use of existing buildings through renovations. The analysis is carried out for 10 different socio-economic regions of the world, taking into account existing building stock and energy intensities in each region and projected changes in population and income, which in most parts of the world will drive large increases in building floor area. A stock turnover model is applied to project changes in heating, cooling, service hot water (SHW) and non-thermal electricity demand with various rates of improvement in standards for new and renovated buildings, and various rates of renovation and demolition of existing buildings. For a scenario in which population peaks at about 9 billion and global average per capita GDP increases to twice the 2010 value by 2100, the global fuel demand could be reduced by a factor of four while limiting maximum annual electricity demand to twice the 2010 value. - Highlights: • A detailed model for generating global scenarios of building energy use is presented. • Drivers of increasing energy use are population and per capita GDP in 10 regions. • Heating, cooling and ventilation energy uses are projected using a stock turnover model. • Global building fuel demand could decrease by 60–80% by 2100 relative to 2010. • Global building electricity demand could be limited to a 100–200% increase

2018-02-01

Building on centuries of research based on herbarium specimens gathered through time and around the globe, a new era of discovery, synthesis, and prediction using digitized collections data has begun. This paper provides an overview of how aggregated, open access botanical and associated biological, environmental, and ecological data sets, from genes to the ecosystem, can be used to document the impacts of global change on communities, organisms, and society; predict future impacts; and help to drive the remediation of change. Advocacy for botanical collections and their expansion is needed, including ongoing digitization and online publishing. The addition of non-traditional digitized data fields, user annotation capability, and born-digital field data collection enables the rapid access of rich, digitally available data sets for research, education, informed decision-making, and other scholarly and creative activities. Researchers are receiving enormous benefits from data aggregators including the Global Biodiversity Information Facility (GBIF), Integrated Digitized Biocollections (iDigBio), the Atlas of Living Australia (ALA), and the Biodiversity Heritage Library (BHL), but effective collaboration around data infrastructures is needed when working with large and disparate data sets. Tools for data discovery, visualization, analysis, and skills training are increasingly important for inspiring novel research that improves the intrinsic value of physical and digital botanical collections.

Global investment in biomedical research has grown significantly over the last decades, reaching approximately a quarter of a trillion US dollars in 2010. However, not all of this investment is distributed evenly by gender. It follows, arguably, that scarce research resources may not be optimally invested (by either not supporting the best science or by failing to investigate topics that benefit women and men equitably). Women across the world tend to be significantly underrepresented in research both as researchers and research participants, receive less research funding, and appear less frequently than men as authors on research publications. There is also some evidence that women are relatively disadvantaged as the beneficiaries of research, in terms of its health, societal and economic impacts. Historical gender biases may have created a path dependency that means that the research system and the impacts of research are biased towards male researchers and male beneficiaries, making it inherently difficult (though not impossible) to eliminate gender bias. In this commentary, we - a group of scholars and practitioners from Africa, America, Asia and Europe - argue that gender-sensitive research impact assessment could become a force for good in moving science policy and practice towards gender equity. Research impact assessment is the multidisciplinary field of scientific inquiry that examines the research process to maximise scientific, societal and economic returns on investment in research. It encompasses many theoretical and methodological approaches that can be used to investigate gender bias and recommend actions for change to maximise research impact. We offer a set of recommendations to research funders, research institutions and research evaluators who conduct impact assessment on how to include and strengthen analysis of gender equity in research impact assessment and issue a global call for action.

Background Tens of millions of patients worldwide suffer disabling injuries or death every year due to unsafe medical care. Nonetheless, there is a scarcity of research evidence on how to tackle this global health priority. The shortage of trained researchers is a major limitation, particularly in developing and transitional countries. Objectives As a first step to strengthen capacity in this area, the authors developed a set of internationally agreed core competencies for patient safety research worldwide. Methods A multistage process involved developing an initial framework, reviewing the existing literature relating to competencies in patient safety research, conducting a series of consultations with potential end users and international experts in the field from over 35 countries and finally convening a global consensus conference. Results An initial draft list of competencies was grouped into three themes: patient safety, research methods and knowledge translation. The competencies were considered by the WHO Patient Safety task force, by potential end users in developing and transitional countries and by international experts in the field to be relevant, comprehensive, clear, easily adaptable to local contexts and useful for training patient safety researchers internationally. Conclusions Reducing patient harm worldwide will require long-term sustained efforts to build capacity to enable practical research that addresses local problems and improves patient safety. The first edition of Competencies for Patient Safety Researchers is proposed by WHO Patient Safety as a foundation for strengthening research capacity by guiding the development of training programmes for researchers in the area of patient safety, particularly in developing and transitional countries, where such research is urgently needed.

Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2011. The report covers both current status and key trends; by design, it does not provide analysis or forecast the future. Global energy consumption rebounded in 2010 after an overall downturn in 2009. Renewable energy, which experienced no downturn in 2009, continued to grow strongly in all end-use sectors - power, heat and transport - and supplied an estimated 16% of global final energy consumption. Renewable energy accounted for approximately half of the estimated 194 gigawatts (GW) of new electric capacity added globally during the year. Renewables delivered close to 20% of global electricity supply in 2010, and by early 2011 they comprised one quarter of global power capacity from all sources. In several countries, renewables represent a rapidly growing share of total energy supply, including heat and transport

Decarbonizing the European electricity sector. Modeling and policy analysis for electricity and CO_2 infrastructure networks

International Nuclear Information System (INIS)

Oei, Pao-Yu Charly Robin

2016-01-01

This dissertation uses three models to analyze different decarbonization strategies for combating global climate change: The cost minimizing mixed-integer model CCTS-Mod examines the economics of Carbon Capture, Transport, and Storage (CCTS) for the electricity and industry sector; the welfare maximizing quadratically constrained model ELMOD focuses on different trajectories for renewable energy sources (RES) and transmission grid expansions; and the equilibrium model ELCO combines the insights of the individual sectors to a combined CCTS and electricity investment and dispatch model. Modeling results show that an investment in CCTS is beneficial for the iron and steel sector once the CO_2 certificate price exceeds 50 Euros/t CO_2. The threshold is 75 Euros/t CO_2 for the cement industry and 100 Euros/t CO_2 for the electricity sector. Additional revenues from using CO_2 for enhanced oil recovery (CO_2-EOR) lead to an earlier adoption of CCTS in the North Sea region. The lack of economies of scale results in increasing CO_2 storage costs of more than 30%, while transport costs even double. Research from the last years, however, indicates that CCTS is unlikely to play an important role in decarbonizing the electricity sector. The identified reasons for this are incumbents' resistance to structural change, wrong technology choices, over-optimistic cost estimates, a premature focus on energy projects instead of industry, and the underestimation of transport and storage issues. Keeping global temperature rise below 2 C therefore implies the phase-out of fossilfueled power plants and, in particular, of CO_2-intensive coal power plants. The low CO_2 price established by the European Emissions Trading Scheme is insufficient to induce a fuel switch in the medium term. Therefore, supplementary national measures are necessary to reduce coal-based power generation; i.a. feed-in tariffs for RES, minimum CO_2 prices, or emissions performance standards. Analyses for Germany show

2008-04-15

The purpose of this state-of-the-art research paper is to surveying the literature on investment in market based electric power systems as a background for identifying and discussing some important issues in the optimal design and operation of such systems. A fundamental distinction has to be made between investment in the competitive part of the power system (generation and trading) on the one hand and the natural monopoly part (network infrastructure) on the other. The paper starts with a listing and discussion on market characteristics and properties of electric power and goes on to discussing performance criteria and potential sources of market failure for optimal electric power investment. After the literature survey there is a discussion of conditions under which optimal investment may occur. (author). 78 refs., figs

Full Text Available In the vision of Global Research Data Infrastructures (GRDIs, data storage and management plays a crucial role. A successful GRDI will require a common globally interoperable distributed data system, formed out of data centres, that incorporates emerging technologies and new scientific data activities. The main challenge is to define common certification and auditing frameworks that will allow storage providers and data communities to build a viable partnership based on trust. To achieve this, it is necessary to find a long-term commitment model that will give financial, legal, and organisational guarantees of digital information preservation. In this article we discuss the state of the art in data storage and management for GRDIs and point out future research directions that need to be tackled to implement GRDIs.

To establish global research priorities for interpersonal violence prevention using a systematic approach. Research priorities were identified in a three-round process involving two surveys. In round 1, 95 global experts in violence prevention proposed research questions to be ranked in round 2. Questions were collated and organized according to the four-step public health approach to violence prevention. In round 2, 280 international experts ranked the importance of research in the four steps, and the various substeps, of the public health approach. In round 3, 131 international experts ranked the importance of detailed research questions on the public health step awarded the highest priority in round 2. In round 2, "developing, implementing and evaluating interventions" was the step of the public health approach awarded the highest priority for four of the six types of violence considered (i.e. child maltreatment, intimate partner violence, armed violence and sexual violence) but not for youth violence or elder abuse. In contrast, "scaling up interventions and evaluating their cost-effectiveness" was ranked lowest for all types of violence. In round 3, research into "developing, implementing and evaluating interventions" that addressed parenting or laws to regulate the use of firearms was awarded the highest priority. The key limitations of the study were response and attrition rates among survey respondents. However, these rates were in line with similar priority-setting exercises. These findings suggest it is premature to scale up violence prevention interventions. Developing and evaluating smaller-scale interventions should be the funding priority.

Highlights: • Integrated assessment model perform a series of scenarios of technology advances. • Explore the potential roles of wind energy technology advance in global energy. • Technology advance impacts on energy consumption and global low carbon market. • Technology advance influences on global energy security and stability. - Abstract: To avoid additional global warming and environmental damage, energy systems need to rely on the use of low carbon technologies like wind energy. However, supply uncertainties, production costs, and energy security are the main factors considered by the global economies when reshaping their energy systems. Here, we explore the potential roles of wind energy technology advancement in future global electricity generations, costs, and energy security. We use an integrated assessment model performing a series of technology advancement scenarios. The results show that double of the capital cost reduction causes 40% of generation increase and 10% of cost ​decrease on average in the long-term global wind electricity market. Today’s technology advancement could bring us the benefit of increasing electricity production in the future 40–50 years, and decreasing electricity cost in the future 90–100 years. The technology advancement of wind energy can help to keep global energy security and stability. An aggressive development and deployment of wind energy could in the long-term avoid 1/3 of gas and 1/28 of coal burned, and keep 1/2 biomass and 1/20 nuclear fuel saved from the global electricity system. The key is that wind resources are free and carbon-free. The results of this study are useful in broad coverage ranges from innovative technologies and systems of renewable energy to the economic industrial and domestic use of energy with no or minor impact on the environment.

The goal of this paper is to undertake a panel data investigation of long-run Granger causality between electricity consumption and real GDP for seven panels, which together consist of 93 countries. We use a new panel causality test and find that in the long-run both electricity consumption and real GDP have a bidirectional Granger causality relationship except for the Middle East where causality runs only from GDP to electricity consumption. Finally, for the G6 panel the estimates reveal a negative sign effect, implying that increasing electricity consumption in the six most industrialised nations will reduce GDP. (author)

This synthesis article joins the authors of the special issue "Gender perspectives in resilience, vulnerability and adaptation to global environmental change" in a common reflective dialogue about the main contributions of their papers. In sum, here we reflect on links between gender and feminist approaches to research in adaptation and resilience in global environmental change (GEC). The main theoretical contributions of this special issue are threefold: emphasizing the relevance of power relations in feminist political ecology, bringing the livelihood and intersectionality approaches into GEC, and linking resilience theories and critical feminist research. Empirical insights on key debates in GEC studies are also highlighted from the nine cases analysed, from Europe, the Americas, Asia, Africa and the Pacific. Further, the special issue also contributes to broaden the gender approach in adaptation to GEC by incorporating research sites in the Global North alongside sites from the Global South. This paper examines and compares the main approaches adopted (e.g. qualitative or mixed methods) and the methodological challenges that derive from intersectional perspectives. Finally, key messages for policy agendas and further research are drawn from the common reflection.

Today we have an incomplete picture of how much the world is spending on health and disease-related research and development (R&D). As such it is difficult to align, or even begin to coordinate, health R&D investments with international public health priorities. Current efforts to track and map global health research investments are complex, resource-intensive, and caveat-laden. An ideal situation would be for all research funding to be classified using a set of common standards and definitions. However, the adoption of such a standard by everyone is not a realistic, pragmatic or even necessary goal. It is time for new thinking informed by the innovations in automated online translation - e.g. Yahoo's Babel Fish. We propose a feasibility study to develop a system that can translate and map the diverse research classification systems into a common standard, allowing the targeting of scarce research investments to where they are needed most.

The JPL Electric and Hybrid Vehicle System Research and Development Project was established in the spring of 1977. Originally administered by the Energy Research and Development Administration (ERDA) and later by the Electric and Hybrid Vehicle Division of the U.S. Department of Energy (DOE), the overall Program objective was to decrease this nation's dependence on foreign petroleum sources by developing the technologies and incentives necessary to bring electric and hybrid vehicles successfully into the marketplace. The ERDA/DOE Program structure was divided into two major elements: (1) technology research and system development and (2) field demonstration and market development. The Jet Propulsion Laboratory (JPL) has been one of several field centers supporting the former Program element. In that capacity, the specific historical areas of responsibility have been: (1) Vehicle system developments (2) System integration and test (3) Supporting subsystem development (4) System assessments (5) Simulation tool development.

Global energy futures and human development: a framework for analysis

2001-01-01

This paper explores the relationship between measures of human well-being and consumption of energy and electricity. A correlation is shown between the United Nations Human Development Index (HDI) and annual per- capita electricity consumption for 60 populous countries comprising 90% of the world population. In this correlation, HDI reaches a maximum value when electricity consumption is about 4,000 kWh per person per year, well below consumption levels for most developed countries but also well above the level for developing countries. The correlation with electricity use is better than with total primary energy use. Global electricity consumption associated with a ''Human Development Scenario'' is estimated by adding to U.S. Department of Energy projections for the year 2020 increments of additional electricity consumption sufficient to reach 4,000 kWh per capita on a country-by-country basis. A roughly constant ratio of primary energy consumption to electric energy consumption is observed for countries with high levels of electricity use, and this ratio is used to estimate global primary energy consumption in the Human Development Scenario. The Human Development Scenario implies significantly greater global consumption of electricity and primary energy than do projections for 2020 by the DOE and others. (author)

Water availability and water demands are essential factors for estimating water scarcity conditions. To reproduce historical observations and to quantify future changes in water availability and water demand, two open source tools have been developed by the JGCRI (Joint Global Change Research Institute): Xanthos and GCAM-STWD. Xanthos is a gridded global hydrologic model, designed to quantify and analyze water availability in 235 river basins. Xanthos uses a runoff generation and a river routing modules to simulate both historical and future estimates of total runoff and streamflows on a monthly time step at a spatial resolution of 0.5 degrees. GCAM-STWD is a spatiotemporal water disaggregation model used with the Global Change Assessment Model (GCAM) to spatially downscale global water demands for six major enduse sectors (irrigation, domestic, electricity generation, mining, and manufacturing) from the region scale to the scale of 0.5 degrees. GCAM-STWD then temporally downscales the gridded annual global water demands to monthly results. These two tools, written in Python, can be integrated to assess global, regional or basin-scale water scarcity or water stress. Both of the tools are extensible to ensure flexibility and promote contribution from researchers that utilize GCAM and study global water use and supply.

There are a lot of research themes in the field of urban planning and related fields as mitigation of global environment change. Main theme is reduction method of CO{sub 2} gas emission as a countermeasure against global warming. Some groups research on estimation of CO{sub 2} emission caused by construction activities both in building engineering and civil engineering and also on evaluation of countermeasures. They investigate reduction of CO{sub 2} emission by fossil fuel combustion and by building materials (cement, steel and so on) production process. But we cannot use data fitted to a spatial scale of urban planning. Many researches are focused on nation wide analysis. We, BRI, make a study of {open_quotes}Research on CO{sub 2} Emission in Urban Development and the Control Technologies{close_quotes} as will be seen later at 2. (2). There are two ways of research to reduce CO{sub 2} emission caused by daily activities to urban planning field. One is research on positive utilizing of natural environment in urban areas without depending to energy consuming artificial facilities. There is a research on mitigation of heat island phenomenon for instance. The other ways are research on improvement of energy consumption effect and on reusing of wasted energy In energy consuming type urban space for instance. There s a research on promoting District Heating and Cooling (DHC) and cogeneration.

The fact that electric-powered vehicles do not emit pollutants locally is obvious and must be considered as the main motive for their use. The global air pollution situation can only be of secondary importance because within the foreseeable future emissions linked to the use of electric-powered vehicles will remain within the variation width of power generation emissions that is not to be influenced. All the same, it is indispensable to consider the global situation. The author compares electric-powered vehicles with conventional ones by referring to the power generation of all federal German states. (orig.) [de

Enablers towards establishing and growing South Africa's waste to electricity industry.

Amsterdam, Heinrich; Thopil, George Alex

2017-10-01

In South Africa the electricity generation mix is relatively un-diverse whereas globally the transformation of the sector is advancing rapidly. Coal remains the predominant fuel source and limited success has to date been achieved in the renewable energy sector. The electricity generation sector is therefore hindered from moving towards an electricity generation landscape where alternative fuel sources is utilised. This research is aimed at gaining insight into the enablers that led towards an increasing trend (observed globally) in exploiting waste as a fuel for electricity generation, and to outline the presence of obstacles that hinder separation of waste for electricity use in the South African context. Furthermore it is an attempt at informing what appropriate interventions (operational and policy) may be considered suitable for South Africa to overcome these barriers in order to enable a sustainable South African waste to electricity (WTE) Industry. Findings show that numerous barriers to a WTE exists in the South African context, however overcoming these barriers is not as simple as adopting the European model with the aim to modify the electricity generation mix and waste management landscape. Selected enablers deemed appropriate in the South African context are adapted from the European model, and are greatly influenced by the prevailing socio-economic status of South Africa. Primary enablers identified were, (i) government support is needed especially in the form of subsidisation for green energy, (ii) increase landfill costs through the implementation of a landfill tax, (iii) streamline the process for Independent Private Power Producers (IPPPs) to connect to the national grid with off-take guaranteed and the inclusion of WTE into an electricity roadmap (effectively government's strategy). The proposed enabling interventions would help in overcoming the barriers for a South African WTE industry. Copyright © 2017 Elsevier Ltd. All rights reserved.

As the burden of noncommunicable diseases (NCDs) rises in settings with an equally high burden of infectious diseases in the Global South, a new sense of urgency has developed around research capacity building to promote more effective and sustainable public health and health care systems. In 2010, NCDs accounted for more than 2.06 million deaths in sub-Saharan Africa. Available evidence suggests that the number of people in sub-Saharan Africa with hypertension, a major risk factor for cardiovascular diseases, will increase by 68% from 75 million in 2008 to 126 million in 2025. Furthermore, about 27.5 million people currently live with diabetes in Africa, and it is estimated that 49.7 million people living with diabetes will reside in Africa by 2030. It is therefore necessary to centralize leadership as a key aspect of research capacity building and strengthening in the Global South in ways that enables researchers to claim their spaces in their own locations. We believe that building capacity for transformative leadership in research will lead to the development of effective and appropriate responses to the multiple burdens of NCDs that coexist with infectious diseases in Africa and the rest of the Global South. © 2016 Society for Public Health Education.

Decarbonizing the European electricity sector. Modeling and policy analysis for electricity and CO{sub 2} infrastructure networks

This dissertation uses three models to analyze different decarbonization strategies for combating global climate change: The cost minimizing mixed-integer model CCTS-Mod examines the economics of Carbon Capture, Transport, and Storage (CCTS) for the electricity and industry sector; the welfare maximizing quadratically constrained model ELMOD focuses on different trajectories for renewable energy sources (RES) and transmission grid expansions; and the equilibrium model ELCO combines the insights of the individual sectors to a combined CCTS and electricity investment and dispatch model. Modeling results show that an investment in CCTS is beneficial for the iron and steel sector once the CO{sub 2} certificate price exceeds 50 Euros/t CO{sub 2}. The threshold is 75 Euros/t CO{sub 2} for the cement industry and 100 Euros/t CO{sub 2} for the electricity sector. Additional revenues from using CO{sub 2} for enhanced oil recovery (CO{sub 2}-EOR) lead to an earlier adoption of CCTS in the North Sea region. The lack of economies of scale results in increasing CO{sub 2} storage costs of more than 30%, while transport costs even double. Research from the last years, however, indicates that CCTS is unlikely to play an important role in decarbonizing the electricity sector. The identified reasons for this are incumbents' resistance to structural change, wrong technology choices, over-optimistic cost estimates, a premature focus on energy projects instead of industry, and the underestimation of transport and storage issues. Keeping global temperature rise below 2 C therefore implies the phase-out of fossilfueled power plants and, in particular, of CO{sub 2}-intensive coal power plants. The low CO{sub 2} price established by the European Emissions Trading Scheme is insufficient to induce a fuel switch in the medium term. Therefore, supplementary national measures are necessary to reduce coal-based power generation; i.a. feed-in tariffs for RES, minimum CO{sub 2} prices, or

The aim is to elucidate the dynamic interactive pricing, competition and market mechanisms that are valid for the European electric power market. The perspective in the report is to analyse the vertical flow of substance and values of energy, the interaction of the actors, and the economic relations. The first link in the vertical chain is the energy raw materials supplies: the reserves and production of fossil and nuclear fuels and the relation to globalization of electricity production. The next link is the production of electricity: the production technologies used and their positioning, the importance of large trans-national utilities in relation to technological changes. The third link is the market and the changes of the market between production, transmission, distribution and consumption of electricity, and the consequences of these changes. Two horizontal regulating sectional views are analysed: The European Union regulations of the electric power sector and the Danish regulations of power supplies. Finally, production and competition of electric power from renewable energy sources, i.e. wind power, in a future European energy market is put into perspective. (LN) 134 refs

Global health issues are concerns of all public health officials throughout the world. This entails reviewing aspects such as the impact of poverty and the lack of access to quality health care, ignored global killers such as Diseases (Infectious diseases-Malaria, HIV/AIDS), Natural Disasters (Earthquakes, Tsunamis, Floods, and Armed Conflict), Health in the Media, and the Involvement of Pharmaceutical Corporations and Medical Research. These issues are challenges to many needless deaths. Global initiatives are not advancing as they should, such as access to drugs and medications, which some are political.

Transportation is the key industry of urban energy consumption and carbon emissions. The transformation of conventional gasoline vehicles to new energy vehicles is an important initiative to realize the goal of developing low-carbon city through energy saving and emissions reduction, while electric vehicles (EV) will play an important role in this transition due to their advantage in energy saving and lower carbon emissions. After reviewing the existing researches on energy saving and emissions reduction of electric vehicles, this paper analyzed the factors affecting carbon emissions reduction. Combining with electric vehicles promotion program in Beijing, the paper analyzed carbon emissions and reduction potential of electric vehicles in six scenarios using the optimized energy consumption related carbon emissions model from the perspective of fuel life cycle. The scenarios included power energy structure, fuel type (energy consumption per 100 km), car type (CO2 emission factor of fuel), urban traffic conditions (speed), coal-power technologies and battery type (weight, energy efficiency). The results showed that the optimized model was able to estimate carbon emissions caused by fuel consumption more reasonably; electric vehicles had an obvious restrictive carbon reduction potential with the fluctuation of 57%-81.2% in the analysis of six influencing factors, while power energy structure and coal-power technologies play decisive roles in life-cycle carbon emissions of electric vehicles with the reduction potential of 78.1% and 81.2%, respectively. Finally, some optimized measures were proposed to reduce transport energy consumption and carbon emissions during electric vehicles promotion including improving energy structure and coal technology, popularizing energy saving technologies and electric vehicles, accelerating the battery R&D and so on. The research provides scientific basis and methods for the policy development for the transition of new energy vehicles
