  2. Assessment of impacts from different waste treatment and waste disposal technologies: Regional Management Plan

    International Nuclear Information System (INIS)

    Robertson, B.C.; Sutherland, A.A.

    1986-01-01

    This report presents assessments of treatment and disposal technologies that appear to be appropriate for use in regional facilities in the Midwest Compact Region. The treatment technologies assessed: compaction with a supercompactor; incineration; and incineration followed by solidfication of the incinerator ash. The disposal technologies assessed are: shallow land burial, considered a baseline for comparison of other technologies; below-ground vaults; abov-groudn vaults; the earth mounded concrete bunker, a technology developed in France; improved shallow land burial, essentially deeper burial; modular concrete canister disposal; mined cavities (both new and existing); and unlined augered holes; and lined augered holes. The teatment technologies are assessed primarily in terms of the their impact on the waste management system, and generally not comparatively. The dispoal technologies are assessed relative to the present standard practice shallow land burial; shallow land burial was slected as a frame of reference because it has an experience base spanning several decades, not because of any preferential characteristics. 20 refs., 5 tabs

    Biomass action plans in many European countries seek to expand biomass heat and fuel supply, mainly to be supplied by peripheral, agricultural regions. We develop a two-plus-ten-region energy-focused computable general equilibrium (CGE) model that acknowledges land competition in analysing the sub-state local-regional economic implications of such a strategy, embedded within a global context. Our model is based on a full cost analysis of selected biomass technologies covering a range of agricultural and forestry crops, as well as thermal insulation. The local-regional macroeconomic effects differ significantly across technologies and are governed by factors such as net labour intensity in crop production. The high land intensity of agricultural biomass products crowds out conventional agriculture, and thus lowers employment and drives up land prices and the consumer price index. The regional economic results show that net employment effects are positive for all forestry based biomass energy, and also show for which agriculture based biomass systems this is true, even when accounting for land competition. When regional consumer price development governs regional wages or when the agricultural sector is in strong enough competition to the international market, positive employment and welfare impacts vanish fully for agriculture based bio-energy.

    Resource over-exploitation and resource depletion have received increasing attentions, especially for industrial regions. In this paper an innovative method that combines emergy analysis and an IPAT (Human Impact Population Affluence Technology) equation is developed in order to create an integrated framework for uncovering the driving forces on resource consumption in one industrial region. Liaoning province, one of the old heavy industrial bases in China, is selected as the case study region. The main results show that total emergy of Liaoning province increased from 9.25E + 23 sej in 2002 to 1.92E + 24 sej in 2012, with 165% growth on non-renewable emergy and 250% growth on imported emergy. Regional emergy/RMB ratio was higher than other developed regions and the average value of China, indicating that this province consumed more local free non-renewable resources to support its own development. The lower ESI (emergy sustainability index) indicates that Liaoning province's sustainability is still weak and far away from sustainable development. IPAT analysis further identifies that rapid economic growth was the main driving force to increase its total emergy use, while technology innovation offset the increase of total emergy use. Policy insights suggest that industrial regions should improve their energy efficiency and optimize their economic and energy structure by applying economic instruments and capacity building efforts. - Highlights: • Emergy analysis and IPAT are combined to evaluate the sustainability of Liaoning. • Total emergy of Liaoning increased from 2002 to 2011 and then decreased in 2012. • Economic scale is the key driving force to induce higher emergy consumption. • Valuable policy insights are proposed in order to promote sustainable development.

    HarvestChoice (harvestchoice.org) generates knowledge products to guide strategic investments to improve the productivity and profitability of smallholder farming systems in sub-Saharan Africa (SSA). A keynote component of the HarvestChoice analytical framework is a grid-based overlay of SSA - a cropping simulation platform powered by process-based, crop models. Calibrated around the best available representation of cropping production systems in SSA, the simulation platform engages the DSSAT Crop Systems Model with the CENTURY Soil Organic Matter model (DSSAT-CENTURY) and provides a virtual experimentation module with which to explore the impact of a range of technological, managerial and environmental metrics on future crop productivity and profitability, as well as input use. For each of 5 (or 30) arc-minute grid cells in SSA, a stack of model input underlies it: datasets that cover soil properties and fertility, historic and future climate scenarios and farmers' management practices; all compiled from analyses of existing global and regional databases and consultations with other CGIAR centers. Running a simulation model is not always straightforward, especially when certain cropping systems or management practices are not even practiced by resource-poor farmers yet (e.g., precision agriculture) or they were never included in the existing simulation framework (e.g., water harvesting). In such cases, we used DSSAT-CENTURY as a function to iteratively estimate relative responses of cropping systems to technology-driven changes in water and nutrient balances compared to zero-adoption by farmers, while adjusting model input parameters to best mimic farmers' implementation of technologies in the field. We then fed the results of the simulation into to the economic and food trade model framework, IMPACT, to assess the potential implications on future food security. The outputs of the overall simulation analyses are packaged as a web-accessible database and published

    Ever since the Apollo program ended, the development of launch propulsion systems in the US has fallen drastically, with only two new booster engine developments, the SSME and the RS-68, occurring in the past few decades.1 In recent years, however, there has been an increased interest in pursuing more effective launch propulsion technologies in the U.S., exemplified by the NASA Office of the Chief Technologist s inclusion of Launch Propulsion Systems as the first technological area in the Space Technology Roadmaps2. One area of particular interest to both government agencies and commercial entities has been the development of hydrocarbon engines; NASA and the Air Force Research Lab3 have expressed interest in the use of hydrocarbon fuels for their respective SLS Booster and Reusable Booster System concepts, and two major commercially-developed launch vehicles SpaceX s Falcon 9 and Orbital Sciences Antares feature engines that use RP-1 kerosene fuel. Compared to engines powered by liquid hydrogen, hydrocarbon-fueled engines have a greater propellant density (usually resulting in a lighter overall engine), produce greater propulsive force, possess easier fuel handling and loading, and for reusable vehicle concepts can provide a shorter turnaround time between launches. These benefits suggest that a hydrocarbon-fueled launch vehicle would allow for a cheap and frequent means of access to space.1 However, the time and money required for the development of a new engine still presents a major challenge. Long and costly design, development, testing and evaluation (DDT&E) programs underscore the importance of identifying critical technologies and prioritizing investment efforts. Trade studies must be performed on engine concepts examining the affordability, operability, and reliability of each concept, and quantifying the impacts of proposed technologies. These studies can be performed through use of the Technology Impact Forecasting (TIF) method. The Technology Impact

    2016-04-01

    During the last decades, natural hazard impacts on social and economic development in many countries were increasing due to the expansion of human activities into the areas prone to natural risks as well as to increasing in number and severity of natural hazardous events caused by climate changes and other natural phenomena. The escalation of severe disasters (such as Tohoku earthquake and tsunami in Japan 2011) triggered by natural hazards and related natural-technological and environmental events is increasingly threatening sustainable development at different levels from regional to global scale. In our study, we develop a model of ecological, economic and social sustainable development for the European part of Russia and the Republic of Belarus. The model consists of six blocks including 1) population, 2) environment, 3) mineral resources, 4) geographic space, 5) investments, and 6) food production and import. These blocks were created based on the analysis of the main processes at the regional level; all the blocks are closely interrelated between each other. Reaching the limit values of block parameters corresponds to a sharp deterioration of the system; as a result, the system can lose its stability. Aggravation of natural and natural-technological risk impacts on each block and should be taken into account in the model of regional development. Natural hazards can cause both strong influences and small but permanent perturbations. In both cases, a system can become unstable. The criterion for sustainable development is proposed. The Russian Foundation for Humanities and Belorussian Republican Foundation for Fundamental Research supported the study (project 15-22-01008).

    1979-03-01

    This report has data on population, administration, finance, housing, health and safety, human services, education, and water and sewage for 325 energy-impacted communities. A review of current and potential energy developments in the region shows over 900 energy resource impacts listed for the 325 impacted communities. Coal development represents over one-third of the developments listed. Communities reporting coal development are distributed as follows: Colorado (36), Montana (42), North Dakota (61), South Dakota (13), Utah (73), and Wyoming (35). Energy-conversion initiatives represent another high incidence of energy-resource impact, with uranium development following closely with 83 communities reporting uranium development impact in the region. These projections indicate continued development of regional energy resources to serve national energy requirements. The 325 impacted communities as reported: Colorado (46), Montana (73), North Dakota (62), South Dakota (21), Utah (80), and Wyoming (43) follow a distribution pattern similar to that of future projects which illustrates that no area of the region will escape the impacts of energy development.

We analyze arrays of vegetation indices and complex spectral transformations derived from processed long-term (1973-2013) satellite data for areas around the cities of Arkhangelsk and Zapolyarny (Murmansk oblast). These data have been used to evaluate the changes in the state of the environment and reveal areas of peak anthropogenic impacts causing significant morphologic changes in all kinds of geosystems and strongly affecting the Arctic natural ecosystems. We have identified the impact regions that are subjected to peak anthropogenic impact and found that these areas are associated with specific industrial facilities.

    The environmental impacts of land use vary regionally. Differences in geomorphology, climate, landscape structure, and biotope inventories are regarded as the main causes of this variation. We present a methodological approach for identifying regional responses in land use type to large-scale changes and the implications for the provision of habitat for farmland birds. The methodological innovations of this approach are (i) the coupling of impact assessments with economic models, (ii) the linking of cropping techniques at the plot scale with the regional distribution of land use, and (iii) the integration of statistical or monitoring data on recent states. This approach allows for the regional differentiation of farmers' responses to changing external conditions and for matching the ecological impacts of land use changes with regional environmental sensitivities. An exemplary scenario analysis was applied for a case study of an area in Germany, assessing the impacts of increased irrigation and the promotion of energy cropping on farmland birds, evaluated as a core indicator for farmland biodiversity. The potential effects on farmland birds were analyzed based on the intrinsic habitat values of the crops and cropping techniques. The results revealed that the strongest decrease in habitat availability for farmland birds occurred in regions with medium-to-low agricultural yields. As a result of the limited cropping alternatives, the increase in maize production was highest in marginal regions for both examined scenarios. Maize production replaced many crops with good-to-medium habitat suitability for birds. The declines in habitat quality were strongest in regions that are not in focus for conservation efforts for farmland birds.

    The Region 4 Market Description Summary provides information that can be used in developing an understanding of the potential markets for clean coal technologies (CCTs) in the South Atlantic Region. This region (which geographically is Federal Region 4) consists of the following eight states: Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee. In order to understand the potential market. A description is provided of the region's energy use, power generation capacity, and potential growth. Highlights of state government activities that could have a bearing on commercial deployment of CCTs are also presented. The potential markets characterized in this summary center on electric power generation by investor-owned, cooperative, and municipal electric utilities and involve planned new capacity additions and actions taken by utilities to comply with Phases I and II of the Clean Air Act Amendments (CAAA) of 1990. Regulations, policies, utility business strategies, and organizational changes that could impact the role of CCTs as a utility option are identified and discussed. The information used to develop the Region 4 Market Description is based mainly on an extensive review of plans and annual reports of 29 investor-owned, cooperative, and municipal coal-using electric utilities and public information on strategies and actions for complying with the CAAA of 1990

    This study of economic and social impacts of nuclear power facilities compares a nuclear energy center (NEC) consisting of three surrogate sites in Ocean County, New Jersey with nuclear facilities dispersed in the Pennsylvania - New Jersey - Maryland area. The NEC studied in this report is assumed to contain 20 reactors of 1200 MW(e) each, for a total NEC capacity of 24,000 MW(e). Following the Introductory chapter, Chapter II discusses briefly the methodological basis for estimating impacts. This part of the analysis only considers impacts of wages and salaries and not purchase of construction materials within the region. Chapters III and IV, respectively, set forth the scenarios of an NEC at each of three sites in Ocean County, N.J. and of a pattern of dispersed nuclear power plants of total equivalent generating capacity. In each case, the economic impacts (employment and income) are calculated, emphasizing the regional effects. In Chapter V these impacts are compared and some more general conclusions are reported. A more detailed analysis of the consequences of the construction of a nuclear power plant is given in Chapter VI. An interindustry (input-output) study, which uses rather finely disaggregated data to estimate the impacts of a prototype plant that might be constructed either as a component of the dispersed scenario or as part of an NEC, is given. Some concluding remarks are given in Chapter VII, and policy questions are emphasized

    2011-07-01

    The IEA's Smart Grids Technology Roadmap identified five global trends that could be effectively addressed by deploying smart grids. These are: increasing peak load (the maximum power that the grid delivers during peak hours), rising electricity consumption, electrification of transport, deployment of variable generation technologies (e.g. wind and solar PV) and ageing infrastructure. Along with this roadmap, a new working paper -- Impact of Smart Grid Technologies on Peak Load to 2050 -- develops a methodology to estimate the evolution of peak load until 2050. It also analyses the impact of smart grid technologies in reducing peak load for four key regions; OECD North America, OECD Europe, OECD Pacific and China. This working paper is a first IEA effort in an evolving modelling process of smart grids that is considering demand response in residential and commercial sectors as well as the integration of electric vehicles.

    SRM geoengineering may ameliorate many of the impacts of greenhouse-induced global warming but also has the potential to drive regional climates outside the envelope of greenhouse-gas induced warming, creating ‘novel’ conditions, and could affect precipitation in some regions disproportionably. We use HadCM3L [Cox et al., 2000] a fully coupled climate model to analyse the regional impacts of different levels of a sunshade SRM intervention on a world with 4 times the pre-industrial CO2 level. We employ a number of new methods to analyse these results, looking at: the regional responses, global aggregation of ‘recipients’ of climate impacts and classifying ‘novel’ climate conditions [Irvine et al., 2010]. We find that the precipitation impacts of SRM differ strongly between regions, with most regions drying but with others becoming wetter with increased levels of SRM. We show that the ‘optimal’ level of SRM for each region would differ, for example in our simulations the USA becomes drier at higher levels of SRM, with pre-industrial precipitation conditions restored at ~50% SRM, whereas Australia starts much drier at 4xCO2 and gets wetter with increasing SRM, returning to pre-industrial precipitation conditions at 100% SRM. ‘Novel’ precipitation conditions, such as the drier-than-pre-industrial conditions in the USA, are experienced across a large fraction of the Earth for all but the lowest levels of SRM, whereas ‘novel’ (cooler) temperature conditions only occur at the highest levels of geoengineering in tropical regions [Govindasamy et al., 2003]. This work shows that the impacts of SRM differ strongly between regions and that a large fraction of the world would have to contend with a regional climate that is ‘novel’ in some way, i.e. with more extreme changes than due to global warming alone. However, we find that it may be possible to identify a level of SRM geoengineering capable of meeting multiple mitigation targets, such as

    1994-01-01

    The objective of this paper is to present a broad overview of the potential environmental impacts of biomass energy from energy crops. The subject is complex because the environmental impact of using biomass for energy must be considered in the context of alternative energy options while the environmental impact of producing biomass from energy crops must be considered in the context of the alternative land-uses. Using biomass-derived energy can reduce greenhouse gas emissions or increase them; growing biomass energy crops can enhance soil fertility or degrade it. Without knowing the context of the biomass energy, one can say little about its specific environmental impacts. The primary focus of this paper is an evaluation of the environmental impacts of growing energy crops. I present an approach for quantitatively evaluating the potential environmental impact of growing energy crops at a regional scale that accounts for the environmental and economic context of the crops. However, to set the stage for this discussion, I begin by comparing the environmental advantages and disadvantages of biomass-derived energy relative to other energy alternatives such as coal, hydropower, nuclear power, oil/gasoline, natural gas and photovoltaics

    This chapter discusses a number of economic, social and knowledge impacts of the applications of nuclear technology in Malaysia as well as benchmarking with Japan and the Republic of Korea. Under economic impacts, index of gross value of products and services, index of gross value of exports, index of gross value of training expenditures, and index of total number of human resource trained are developed. In addition, the contribution of the application of nuclear technology to both Gross Domestic Products (GDP) and GDP per capita are also highlighted. The impact of the application of nuclear technology to Total Factor Productivity (TFP) is also covered in this chapter. Much of the discussions on economic impacts are based on findings in private companies. That is because many of their operations can be expressed in monetary terms by virtue of them operating in commercial environment. Public agencies, however, play crucial role in enabling the private companies attain the level of development reported in this study. Towards that end, public agencies invested in Research and development activities, human capital development, as well as in the setting-up, operation and maintenance of both technical and administrative infrastructures. The impact of such activities is discussed in the later part of this chapter. (author)

    Over the past decade technology has changed enormously. Google has made access to information nearly instantaneous while cell phones, which provide connections to both people and data, are now ubiquitous. This has led to large-scale changes in how students live their everyday lives and therefore impacts their expectations of higher education. Professors no longer need to serve as the main sources of content, but students need more guidance than ever to find the ``pearls of truth'' in the great sea of data now before them. This should impact how we do our jobs as instructors. This talk will discuss the impact of technology on students, how they learn, and how our roles as instructors will change.

    The Hypervelocity Impact Society is devoted to the advancement of the science and technology of hypervelocity impact and related technical areas required to facilitate and understand hypervelocity impact phenomena. Topics of interest include experimental methods, theoretical techniques, analytical studies, phenomenological studies, dynamic material response as related to material properties (e.g., equation of state), penetration mechanics, and dynamic failure of materials, planetary physics and other related phenomena. The objectives of the Society are to foster the development and exchange of technical information in the discipline of hypervelocity impact phenomena, promote technical excellence, encourage peer review publications, and hold technical symposia on a regular basis. It was sometime in 1985, partly in response to the Strategic Defense Initiative (SDI), that a small group of visionaries decided that a conference or symposium on hypervelocity science would be useful and began the necessary planning. A major objective of the first Symposium was to bring the scientists and researchers up to date by reviewing the essential developments of hypervelocity science and technology between 1955 and 1985. This Symposia--HVIS 2007 is the tenth Symposium since that beginning. The papers presented at all the HVIS are peer reviewed and published as a special volume of the archival journal International Journal of Impact Engineering. HVIS 2007 followed the same high standards and its proceedings will add to this body of work.

    Advancements in research and technology are transforming our world. The dental profession is changing too, in the light of scientific discoveries that are advancing biological technology-from new biomaterials to unravelling the genetic make-up of the human being. As health professionals, we embrace a model of continuous quality improvement and lifelong learning. Our pedagogical approach to incorporating the plethora of scientific-technological advancements calls for us to shift our paradigm from emphasis on skill acquisition to knowledge application. The 2017 ADEE/ADEA workshop provided a forum to explore and discuss strategies to ensure faculty, students and, ultimately, patients are best positioned to exploit the opportunities that arise from integrating new technological advances and research outcomes. Participants discussed methods of incorporating the impact of new technologies and research findings into the education of our dental students. This report serves as a signpost of the way forward and how to promote incorporation of research and technology advances and lifelong learning into the dental education curriculum. © 2018 John Wiley & Sons A/S.

    Solar energy systems (photovoltaics, solar thermal, solar power) provide significant environmental benefits in comparison to the conventional energy sources, thus contributing, to the sustainable development of human activities. Sometimes however, their wide scale deployment has to face potential negative environmental implications. These potential problems seem to be a strong barrier for a further dissemination of these systems in some consumers. To cope with these problems this paper presents an overview of an Environmental Impact Assessment. We assess the potential environmental intrusions in order to ameliorate them with new technological innovations and good practices in the future power systems. The analysis provides the potential burdens to the environment, which include - during the construction, the installation and the demolition phases, as well as especially in the case of the central solar technologies - noise and visual intrusion, greenhouse gas emissions, water and soil pollution, energy consumption, labour accidents, impact on archaeological sites or on sensitive ecosystems, negative and positive socio-economic effects

    Common features of natural disasters are intense regional impacts and the need for assessing their economic impacts on the construction sectors. The years 2004 and 2005 were record-setting time for natural disasters with major disasters or catastrophic (Cat) events all around the world with dramatic consequences in human lives and economic losses around the world, affecting developed and developing countries. Although there is a large body of literature on assessing the impact of cat events, there is little available research on the quantification and modeling of the regional economic impact of such events on the cost and length of reconstruction. Current available econometric models have serious limitations because they need detailed information for modeling the complex interactions between the different stakeholders of the economy at a regional level that is generally not available. Also, very little research was performed for quantifying the demand surge, defined as the sudden increase in the cost of repairs due to amplified payments, following a hurricane or a series of hurricane events or other natural disasters. Demand surge is an important component of the overall economic impact of cat events and there is a need to better quantify it. This paper presents results of a research program that started after the 2004 and 2005 U.S. hurricane seasons. A large data set of economic and observed losses resulting from the hurricanes that affected Florida and the Gulf states in the US was collected at county level. This provided us with the basis for assessing the change in repair costs before and after these historical events, to quantify the demand surge (after removing the underlying baseline trends) at several dozens of locations across the areas affected, and to provide information on how the changes in demand surge vary spatially and temporally in affected areas for which the amount of structure losses were reported. A parallel research effort was undertaken for

    This paper describes the Agriculture and Resources Regional Technology Information System (ARRTIS) and the Regional Applied Communication Outreach Program (RAC) of PCARRD. The ARRTIS and the RACO are the strategies in communicating scientific and technology-based information. The ARRTIS is an information system that provides an information base on the status of technologies at various levels of maturity (generation, adaptation, verification, piloting, dissemination and utilization) and offers technology alternatives based on environmental requirements, costs and returns analysis or feasibility of the technologies. This information base provides the repository of technology information from which the Applied Communication Program draws its information for packaging into various formats, using various strategies/media to cater to various users in the regions most especially the farmers. Meanwhile, as PCARRD executes its mission of developing the national research system, it incorporates a development support communication program through the RACO. The RACO is essentially a working component of a regional research center/consortium in each region coordinated by the Applied Communication Division of PCARRD. It aims at reaching farmers and their families, extensionists, administrators, policy makers and entrepreneurs with research information and technology which use a variety of appropriate communication channels, modern communication technology and strategies so that they may actively participate in research diffusion and utilization.

    ATP's Mission and Operations. The ATP partners with industry to accelerate the development of innovative technologies for broad national economic benefit. The program's focus is on co-funding collaborative, multi-disciplinary technologies and enabling technology platforms that appear likely to be commercialized, with private sector funding, once the high technical risks are reduced. Industry-led projects are selected for funding in rigorous competitions on the basis of technical and economic merit. Since 1990, ATP has co-funded 642 projects, with 1,329 participants and another 1,300 subcontractors. Measuring to Mission: Overview of ATP's Evaluation Program. ATP's multi-component evaluation strategy provides measures of progress and performance matched to the stage of project evolution; i.e., for the short-term, from the time of project selection and over the course of the R for the mid-term, as commercial applications are pursued, early products reach the market, and dissemination of knowledge created in the R projects occurs; and for the longer-term, as more fully-developed technologies diffuse across multiple products and industries. The approach is applicable to all public S programs and adaptable to private or university projects ranging from basic research to applied industrial R. Examples of Results. ATP's composite performance rating system assesses ATP's completed projects against multi-faceted performance criteria of Knowledge Creation and Dissemination and Commercialization Progress 2-3 years after the end of ATP-funded R. It generates scores ranging from zero to four stars. Results for ATP's first 50 completed projects show that 16are in the bottom group of zero or one stars. 60the middle group. It is understood that not all ATP projects will be successful given the program's emphasis on funding high-risk technology development that the private sector is unwilling and unable to fund alone.

    Full Text Available The “sustainability” concept relates to the prolonging of human economic systems with as little detrimental impact on ecological systems as possible. Construction that exhibits good environmental stewardship and practices that conserve resources in a manner that allow growth and development to be sustained for the long-term without degrading the environment are indispensable in a developed society.Past, current and future advancements in road construction as an environmentally sustainable paving material are especially important because the quantities of asphalt used annually in Europe as well as in the U.S. and all over the world are large. This research project is aimed to demonstrate the dual value of some new technologies in regards to the environmental and mechanical performance and to suggest a low environmental impact design procedure. In fact, the use of eco-friendly materials is the first phase towards an eco-compatible design but it cannot be the only step. The eco-compatible approach should be extended also to the design method and material characterization because only with these phases is it possible to exploit the maximum potential properties of the used materials.

    Full Text Available Technological change has meant that organizations require workers with higher qualifications, development, implementation and adaptation of technology looking to stay at the forefront in international competitiveness. The aim of this paper is to analyze the changes that have occurred in regional labor markets in Mexico on occupational and wage and identify to what extent these changes may have resulted from technological change and if this behavior is spatially homogeneous. The information source is made up of microdata from the National Survey of Urban Employment (Employment Survey 2000–2004. The empirical analysis –considering workers officiating at high and low technological intensity and applying a Mincerian income function with different classification criteria: education, sex, age groups and regions– during the period indicate that there have been significant changes in the Mexican labor market as a result of biased technological change, as it provides statistical evidence indicating the existence of a higher wage premium for subordinates in the technological area, and different effects at the regional level, encouraging more to the border.

    In recent decades the quantity (in weight and volume) of solid waste is grown so rapidly to become a real problem especially in densely urbanized areas. The disposal of Municipal Solid Waste by incineration with energy recovery (WtE) is recognized as the most suitable system to process non-recyclable waste. However in several countries there are still concerns from experts and local communities about the environmental impact of incinerators. Epidemiological studies, developed since the 80s, are still the subject of controversial discussion because the results of research often refer to old incinerators--built a few decades ago--and therefore more impactful. In fact inadequate levels of gas cleaning and combustion process control in these facilities tended to risk the health of plant workers and local environment. This situation furthermore contributes to increase public risk perception and the spread of the NIMBY (not in my backyard) syndrome while siting this unwanted but necessary facilities. Actually, new strategies as advances in emission control designs and very stringent new governmental regulations, have resulted in large reductions in the amount of emissions. So the first aim of this work has been to understand if these high perception of risk have a reason to exist also in modern and new municipal waste incinerators. The second aim is to discover if the law, the new technologies and the mitigation strategies can really set a limit on the negative impacts on human health and on environment and if is it possible to improve or increase these strategies. Work has been divided into two parts. The first part focuses on analysis of waste environmental impact regulations, of plant operation systems and of epidemiological studies results. The second part involves the examination of the actual use of regulatory instruments, the most advanced technologies and the strategies for mitigation in the most effective new concept incinerators plants.

    Ageing is a key challenge for many countries. The purpose of this paper is to simulate how ageing affects future regional labour market outcomes. We develop a simulation procedure based on data for 71 Nordic regions in Finland, Norway, Sweden and Denmark. The procedure combines spatial econometrics...... and population projections for scenario analyses of future employment patterns up to 2021. Compared to a “benchmark scenario” based on projections of the working age population, we find that predicted regional labour market outcomes tell a much richer story if a combination of estimation results and population...

    Full Text Available Regionalism has become one of the most discussed topics at the moment, in recent years and become one of the central challenges of the future in the modern system of international relations. Finally, in the XIX-XX centuries, scientists have expressed it a worldwide phenomenon through a process of radical change "external environment" and significant internal changes. It can be expressed in the world in one way or another, even if it has not been shown modest form until recently. Currently, regionalism and regional integration are considered as key indicators of international developments in the research of foreign policy and international relations. Theory followed the end of the era of "Cold War" and entered the post-bipolar world, multi-faceted development stage. The attention of researchers has grown to regionalization and regional integration by increasing the role and activities of regional organizations such as the EU, ASEAN, APEC and NAFTA, which coordinates the process of decision-making at supranational level, as well as issues of international regulation.

  16. Renewable energy technology applications in the Asian region

    International Nuclear Information System (INIS)

    Charters, W.W.S.

    1996-01-01

    The interest shown by Asia in renewable energy technologies is currently extremely high as the region is expected to account for up to 50 percent of the total world power generation equipment orders over the next ten years. Mature developed technologies for power production from renewable energy resources are now available in the form of micro and mini hydro plants, biomass pyrolysis and gasification units, wind aerogenerators and photovoltaic arrays. If Australia is to move towards a sustainable energy society, renewable energy resources must be utilized on a widespread scale as soon as possible. There are large niche markets for renewable energy resource based equipment in Australia, as well as immense market opportunities in the neighbouring fast growing economies in Asia. Key issues to be addressed in terms of implementing major renewable energy programs in the region on a large scale include identification and encouragement of reliable markets, and mass production of high quality reliable products.

    Hjerpe, Evan E; Kim, Yeon-Su

    2007-10-01

    Economic impact analysis (EIA) of outdoor recreation can provide critical social information concerning the utilization of natural resources. Outdoor recreation and other non-consumptive uses of resources are viewed as environmentally friendly alternatives to extractive-type industries. While outdoor recreation can be an appropriate use of resources, it generates both beneficial and adverse socioeconomic impacts on rural communities. The authors used EIA to assess the regional economic impacts of rafting in Grand Canyon National Park. The Grand Canyon region of northern Arizona represents a rural US economy that is highly dependent upon tourism and recreational expenditures. The purpose of this research is twofold. The first is to ascertain the previously unknown regional economic impacts of Grand Canyon river runners. The second purpose is to examine attributes of these economic impacts in terms of regional multipliers, leakage, and types of employment created. Most of the literature on economic impacts of outdoor recreation has focused strictly on the positive economic impacts, failing to illuminate the coinciding adverse and constraining economic impacts. Examining the attributes of economic impacts can highlight deficiencies and constraints that limit the economic benefits of recreation and tourism. Regional expenditure information was obtained by surveying non-commercial boaters and commercial outfitters. The authors used IMPLAN input-output modeling to assess direct, indirect, and induced effects of Grand Canyon river runners. Multipliers were calculated for output, employment, and income. Over 22,000 people rafted on the Colorado River through Grand Canyon National Park in 2001, resulting in an estimated $21,100,000 of regional expenditures to the greater Grand Canyon economy. However, over 50% of all rafting-related expenditures were not captured by the regional economy and many of the jobs created by the rafting industry are lower-wage and seasonal. Policy

    2017-11-01

    A characteristic trend of many countries modern development is the transition to an innovative economy. At present, this is the only opportunity to secure and maintain a high standard of living for the population. Moreover, innovative development of Russian can be achieved during technological progress in its regions. In this regard, it is necessary to assess the innovative potential of the region and identify the most actual problems that impede the transition to the trajectory of innovative development. The authors outline several main indicators that help to determine the level of innovation and technological development of one of the largest industrial areas of Russia - Kemerovo region. The special economic role of Kemerovo region as a large territorial old-industrial complex of Western Siberia requires a large-scale work to solve the most acute problems of regional development. It is necessary to find the answer for existing problems through the implementation of a system of state regulation aimed at making the innovation component a leading factor of the regional economy competitiveness.

  7. Standards And Their Impact On Technology

    Science.gov (United States)

    Endelman, Lincoln L.

    1990-01-01

    The needs for standards and the processes to provide them are very complex. Standardization is dependent upon voluntary and nonvoluntary agreement among individuals, companies, various organizations, and countries around the world. The agreements on standards, which sometimes take five to ten years, are hindered by monetary considerations, relinquishment of patent rights, disagreement among nations on dimensions in metric or the English system, and professional jealousy among some individuals. Standards, Standards, Standards - what a boring and uninteresting topic. Why did I ever agree to speak to you about something that most people take for granted and don't even bother to pay much attention to until they encounter a situation where a nonstandard item creates a problem. Have any of you ever bought a roll of 35mm film for your foreign made camera and found out that it needs 32mm film? That could have happened to you in the late nineteenth or early twentieth century. Yes, we know that, you say, but that's not a problem anymore. Well, how about when you try to put a Beta cassette into your VCR that uses VHS cassettes? Have you tried to fit a Minolta lens onto a Nikon camera? But enough, you all have the idea. Standards were developed to make interchangeable components compatible with other equipment, no matter who made it or where it was made. Some companies and countries deliberately made things different to protect their inventions and profit by their uniqueness. More and more attempts are being made to reduce the international differences in technology and establish a common ground for trade and commerce. The European Common Market is in the process of eliminating many of the barriers to free exchange of goods, services, and even moving to a universal currency. This all sounds good for Europe, but what about the USA and the rest of the world. The United States has fought the change to the metric system for almost two hundred years.

    Prowse, Terry D; Furgal, Chris; Bonsal, Barrie R; Peters, Daniel L

    2009-07-01

    Understanding the implications of climate change on northern Canada requires a background about the size and diversity of its human and biogeophysical systems. Occupying an area of almost 40% of Canada, with one-third of this contained in Arctic islands, Canada's northern territories consist of a diversity of physical environments unrivaled around the circumpolar north. Major ecozones composed of a range of landforms, climate, vegetation, and wildlife include: Arctic, boreal and taiga cordillera; boreal and taiga plains; taiga shield; and northern and southern Arctic. Although generally characterized by a cold climate, there is an enormous range in air temperature with mean annual values being as high as -5 degrees C in the south to as low as -20 degrees C in the high Arctic islands. A similar contrast characterizes precipitation, which can be > 700 mm y(-1) in some southern alpine regions to as low as 50 mm y(-1) over islands of the high Arctic. Major freshwater resources are found within most northern ecozones, varying from large glaciers or ice caps and lakes to extensive wetlands and peat lands. Most of the North's renewable water, however, is found within its major river networks and originates in more southerly headwaters. Ice covers characterize the freshwater systems for multiple months of the year while permafrost prevails in various forms, dominating the terrestrial landscape. The marine environment, which envelops the Canadian Arctic Archipelago, is dominated by seasonal to multiyear sea ice often several meters thick that plays a key role in the regional climate. Almost two-thirds of northern Canadian communities are located along coastlines with the entire population being just over 100 000. Most recent population growth has been dominated by an expansion of nonaboriginals, primarily the result of resource development and the growth of public administration. The economies of northern communities, however, remain quite mixed with traditional land

  12. Impact of bioenergy on regionalized nitrogen balances

    Häußermann, Uwe; Klement, Laura; Bach, Martin

    2017-04-01

    Results of regionalized and overall net-N-balances are used to fulfil different reporting obligations, as well as input data for nitrate leaching modelling (Bach et al. 2014). For Germany, these regionalized net-N-balances are calculated for 402 administrative units on the NUTS-III-level (Landkreise and kreisfreie Städte in Germany), 16 administrative units on the NUTS-I-level (Bundesländer in Germany) and the whole country for every year from 1995 to 2015. The so far existing net-N-balancing method includes nitrogen inputs and outputs of crop production and animal husbandry, however, not the utilization of crops and farmyard manure for energy production (Bach et al. 2014). Due to the introduction of guaranteed feed in tariffs for electricity production from biomass by the German renewable energy law in 2000 and the introduction of more favourable conditions for electricity production from biogas in 2004 (EEG 2000, EEG 2004) in the frame of the German policy of energy transition towards renewable energies („Energiewende"), the electric capacity of biogas plants had a steep increase in the years afterwards, the installed electric capacity increased from 149 MW in 2004 to 5080 MW in 2015 (BMWi and AGEE Stat 2016). The cropping area for the production of energy cops for biogas production increased as well from 0.4 Mio ha in 2007 to 1.393 Mio ha in 2015 (Statista 2017). We introduced a method to calculate the nitrogen input via energy crops, farmyard manure and organic waste, output via biogas digestates and gaseous nitrogen losses via NH3, N2O, NOx and N2 during the anaerobic digestion, digestate storage and spreading on the field, the emission factors for these nitrogen species are obtained from the report on methods and data for the agricultural part of the German national greenhouse gas inventory and informative inventory report (Haenel et al. 2016). To obtain highly resolved information on the distribution and capacity of biogas plants on NUTS-III-level, we

NASA's aeropropulsion program (primarily conducted through the Lewis Research Center) has significantly contributed to that success through research and technology advances and technology demonstration. Some past NASA contributions to engines in current aircraft are reviewed, and technologies emerging from current research programs for the aircraft of the 1990's are described. Finally, current program thrusts toward improving propulsion systems in the 2000's for subsonic commercial aircraft and higher speed aircraft such as the High-Speed Civil Transport and the National Aerospace Plane are discussed.

  14. Environmental impact on the polar regions

    1994-01-01

    The remote and frigid polar regions are no longer isolated from the activities, pollutants, and controversies that bedevil their more temperate neighbors, say three researchers at the University of Alaska in Fairbanks. For example, Daniel A. Jaffe, Elizabeth Leighton, and Mark A. Tumeo point to traces of DDT, PCBs, and heavy metals that routinely turn up in arctic marine mammals and to the ozone hole over the Antarctic. While similar in environmental makeup, the arctic and Antarctic are poles apart in their political structure and, thus, in their environmental exposure, the researchers note. The Antarctic is managed under a long-standing international treaty, while the arctic is sovereign territory to eight separate nations. The international treaty sets aside the Antarctic for peaceful scientific research within strict environmental boundaries. It bans both military activity and minerals extraction-the two activities that have caused the most damage in the arctic. The main threats to Antarctica's environment come from the intrusion of major scientific research operations and the growing tourism industry. On the other hand, the arctic suffered from the massive Cold War military buildup by both the United States and the former Soviet Union. The environmental residue from that buildup is only now being revealed, the authors say. Major oil and gas drilling and coal and metal-ore mining also have taken a huge environmental toll, they add

    The use of local therapy for prostate cancer may increase because of the perceived advantages of new technologies such as intensity-modulated radiotherapy (IMRT) and robotic prostatectomy. To examine the association of market-level technological capacity with receipt of local therapy. Retrospective cohort. Patients with localized prostate cancer who were diagnosed between 2003 and 2007 (n=59,043) from the Surveillance Epidemiology and End Results-Medicare database. We measured the capacity for delivering treatment with new technology as the number of providers offering robotic prostatectomy or IMRT per population in a market (hospital referral region). The association of this measure with receipt of prostatectomy, radiotherapy, or observation was examined with multinomial logistic regression. For each 1000 patients diagnosed with prostate cancer, 174 underwent prostatectomy, 490 radiotherapy, and 336 were observed. Markets with high robotic prostatectomy capacity had higher use of prostatectomy (146 vs. 118 per 1000 men, P=0.008) but a trend toward decreased use of radiotherapy (574 vs. 601 per 1000 men, P=0.068), resulting in a stable rate of local therapy. High versus low IMRT capacity did not significantly impact the use of prostatectomy (129 vs. 129 per 1000 men, P=0.947) and radiotherapy (594 vs. 585 per 1000 men, P=0.579). Although there was a small shift from radiotherapy to prostatectomy in markets with high robotic prostatectomy capacity, increased capacity for both robotic prostatectomy and IMRT did not change the overall rate of local therapy. Our findings temper concerns that the new technology spurs additional therapy of prostate cancer.

    2017-12-01

    Since the original Institute of Medicine (IOM) report was published there has been an accelerated development and adoption of health information technology with varying degrees of evidence about the impact of health information technology on patient safety.  This article is intended to review the current available scientific evidence on the impact of different health information technologies on improving patient safety outcomes. We conclude that health information technology improves patient's safety by reducing medication errors, reducing adverse drug reactions, and improving compliance to practice guidelines. There should be no doubt that health information technology is an important tool for improving healthcare quality and safety. Healthcare organizations need to be selective in which technology to invest in, as literature shows that some technologies have limited evidence in improving patient safety outcomes.

    Technical change is a key factor in the energy world. Failure to recognize the potential for technical change, and the pace at which it may occur, has limited the accuracy and usefulness of past energy projections. conversely, programs to develop and deploy advanced energy technologies have often proved disappointing in the face of technical and commercial obstacles. This book examines important new and emerging energy technologies, and the mechanisms by which they may develop and enter the market. The project concentrates on the potential and probable role of selected energy technologies-which are in existence and likely to be of rapidly growing importance over the next decade-and the way in which market conditions and policy environment may affect their implementation

  1. Distributional and regional economic impact of energy taxes in Belgium

    International Nuclear Information System (INIS)

    Vandyck, Toon; Van Regemorter, Denise

    2014-01-01

    We analyse the macroeconomic and distributional effects of increased oil excises in Belgium by combining a regional Computable General Equilibrium (CGE) model with a microsimulation framework that exploits the rich detail of household-level data. The link between the CGE model and the microlevel is top–down, feeding changes in commodity prices, factor returns and employment by sector into a microsimulation model. The results suggest that policymakers face an equity-efficiency trade-off driven by the choice of revenue recycling options. When the additional revenue is used to raise welfare transfers to households, the reform is beneficial for lower income groups, but output levels decrease in all regions. However, when the energy tax revenue is used to lower distortionary labour taxes, the tax shift is slightly regressive. In this case, national GDP is hardly affected but regional production levels diverge. The impact of the environmental tax reform on income distribution depends strongly on changes in factor prices and welfare payments, whereas sector composition is an important determinant for regional impact variation. - Highlights: • We study the impact of oil excises across regions and households in Belgium. • Lower income groups gain if the revenue is used to raise welfare payments. • If labour taxes are reduced, the reform is only slightly regressive. • The differential impact across households is driven by factor price changes. • Sector composition is a crucial determinant for impact variation across regions

However, the effective implementation of the majority of these approaches has not been possible only after the advent of new forms of learning (E_learning, M-learning.... These forms are closely related to technological development. Later with the emergence of technology (pervasive computing, Artificial Intelligent ... a new form of learning is established. It is called Pervasive Learning "P-Learning”. P-Learning is a social process that connects learners to communities of devices, people, and situations in a transparent and independent manner. This learning form goes far beyond the predictions suggested by pedagogue. Learning can then take part outside the learner via technology, which will be an extension of his brain by unloading the cognitive practices he performs. The aim of this paper is to answer the following questions: What alliance is there between pedagogy and technology? Are we in need of a new pedagogical approach in the new learning environment "P-Learning"? What are the new pedagogical challenges to resolve?

    Full Text Available Impacts of extreme weather events are relevant for regional (in the sense of subnational economies and in particular cities in many aspects. Cities are the cores of economic activity and the amount of people and assets endangered by extreme weather events is large, even under the current climate. A changing climate with changing extreme weather patterns and the process of urbanization will make the whole issue even more relevant in the future. In this paper, definitions and terminology in the field of extreme weather events are discussed. Possible regional impacts of extreme weather events are collected, focusing on European cities. The human contributions to those impacts are emphasized. Furthermore, methodological aspects of economic impact assessment are discussed along a temporal and a sectoral dimension. Finally, common economic impact models are compared, analyzing their strengths and weaknesses.

    2017-02-01

    Lunar Reconnaissance Orbiter (LRO) Diviner Radiometer, Mini-RF, and LRO Camera data were used to identify and characterize rocky lunar deposits that appear well separated from any potential source crater. Two regions are described: 1) A ∼18,000 km2 area with elevated rock abundance and extensive melt ponds and veneers near the antipode of Tycho crater (167.5°E, 42.5°N). This region has been identified previously, using radar and imaging data. 2) A much larger and more diffuse region, covering ∼730,000 km2, centered near 310°E, 35°S, containing elevated rock abundance and numerous granular flow deposits on crater walls. The rock distributions in both regions favor certain slope azimuths over others, indicating a directional component to the formation of these deposits. The spatial distribution of rocks is consistent with the arrival of ejecta from the west and northwest at low angles (∼10-30°) above the horizon in both regions. The derived age and slope orientations of the deposits indicate that the deposits likely originated as ejecta from the Tycho impact event. Despite their similar origin, the deposits in the two regions show significant differences in the datasets. The Tycho crater antipode deposit covers a smaller area, but the deposits are pervasive and appear to be dominated by impact melts. By contrast, the nearside deposits cover a much larger area and numerous granular flows were triggered. However, the features in this region are less prominent with no evidence for the presence of impact melts. The two regions appear to be surface expressions of a distant impact event that can modify surfaces across wide regions, resulting in a variety of surface morphologies. The Tycho impact event may only be the most recent manifestation of these processes, which likely have played a role in the development of the regolith throughout lunar history.

    2012-01-01

    Managers work to achieve the greatest output for the least input effort, better balancing all factors of delivery to achieve the most with the smallest resource effort. Documentation of actual health information technology (HIT) cost savings has been elusive. Information technology and linear programming help to control hospital costs without harming service quality or staff morale. This study presents production function results from a study of hospital output during the period 2008-2011. The results suggest that productivity varies widely among the 58 hospitals as a function of staffing patterns, methods of organization, and the degree of reliance on information support systems. Financial incentives help to enhance productivity. Incentive pay for staff based on actual productivity gains is associated with improved productivity. HIT can enhance the marginal value product of nurses and staff, so that they concentrate their workday around patient care activities. The implementation of electronic health records (EHR) was associated with a 1.6 percent improvement in productivity.

  16. The Impact of Technology on Education

    Lagowski, J. J.

    1995-08-01

    Near the top of the list of critical issues in education is the appropriate use of technology in the educational process. It is clear that some type of investment in educational technology, specifically interactive computing, is essential for nearly all institutions, and indeed, many have made some purchases already. Despite that fact, the leadership of educational institutions face a complex set of problems in this regard. What portion of a (probably) shrinking budget should be allocated to this expanding area? Which options from a growing array of technological choices are the most appropriate for a particular environment? Which of these options are essentials, and which are luxuries? What sorts of technology will benefit students the most? What is needed now in order to keep from falling (even further) behind a few years hence? The pressure to do something is great, and it is often exacerbated by arguments of efficiency that have little foundation in fact. For example, suggestions are often made that an investment in educational technology will help handle more students. This point of view may ultimately prevail, but little evidence on this point is currently available. Indeed, it appears that more faculty/staff effort is required to bring interactive technology into students' hands in a meaningful way. Often ignored is the amount of training necessary for a spectrum of novice users. Another argument often made is that empowering students with interactive technology will somehow lessen pressure on the current (classical) library operation. Presumably, this effect will come about through access to the Internet resources. As currently constituted, the Internet carries information of widely varying quality, ranging from the systematic holdings of many of the fine libraries of the world to outright garbage (from an intellectual point of view). Information on the Internet (other than that from libraries) is often unedited or unorganized to the extent that potential

    2014-12-01

    Full Text Available The aim of this article is to explain the difference between regionalism and regional development concepts that are often used interchangeably, to investigate the fundamental aspects of two phenomena: regionalism in the sense of “new regionalism” and in the sense of “regional development” at the background of the globalized economy; to check a hypothesis that these two phenomena may be linked together and to study the impact of regionalism on regional integration. The article deepens the concept of “regional development.” At the same time, peculiarities of the current stage of the world economy development under the conditions of globalization are considered. The paper is theoretical (verbal rather than statistical analysis of the nature, diversity and fundamental aspects of regionalism and regional development in general. The article deals with the impact of regionalism on the location of production, and the growth of competition and market expansion systematizes the main effects of regionalism on market expansion and the location of production.

    2011-01-01

    The impacts of the availability of low-carbon technologies on the regional distribution of mitigation costs are analyzed in a global multi-regional integrated assessment model. Three effects on regional consumption losses are distinguished: domestic measures, trade of fossil energy carriers and trade of emission permits. Key results are: (i) GDP losses and a redirection of investments in the energy system towards capital-intensive technologies are major contributions to regional consumption losses. (ii) A devaluation of tradable fossil energy endowments contributes largely to the mitigation costs of fossil fuel exporters. (iii) In case of reduced availability of low-carbon technologies, the permit market volume and associated monetary redistributions increase. The results suggest that the availability of a broad portfolio of low-carbon technologies could facilitate negotiations on the permit allocation scheme in a global cap-and-trade system. - Highlights: → We analyze the distribution of climate change mitigation costs among world regions. → We quantify contributions from various effects on regional costs. → The interference of world trade and low-carbon technologies is essential. → A broad portfolio of technologies helps international negotiations.

  1. Impacts of climate change on mangrove ecosystems: A region by region overview

    Science.gov (United States)

    Ward, Raymond D.; Friess, Daniel A.; Day, Richard H.; MacKenzie, Richard A.

    2016-01-01

    Inter-related and spatially variable climate change factors including sea level rise, increased storminess, altered precipitation regime and increasing temperature are impacting mangroves at regional scales. This review highlights extreme regional variation in climate change threats and impacts, and how these factors impact the structure of mangrove communities, their biodiversity and geomorphological setting. All these factors interplay to determine spatially variable resiliency to climate change impacts, and because mangroves are varied in type and geographical location, these systems are good models for understanding such interactions at different scales. Sea level rise is likely to influence mangroves in all regions although local impacts are likely to be more varied. Changes in the frequency and intensity of storminess are likely to have a greater impact on N and Central America, Asia, Australia, and East Africa than West Africa and S. America. This review also highlights the numerous geographical knowledge gaps of climate change impacts, with some regions particularly understudied (e.g., Africa and the Middle East). While there has been a recent drive to address these knowledge gaps especially in South America and Asia, further research is required to allow researchers to tease apart the processes that influence both vulnerability and resilience to climate change. A more globally representative view of mangroves would allow us to better understand the importance of mangrove type and landscape setting in determining system resiliency to future climate change.

    Budget impact analysis (BIA) provides operational financial forecasts to implement new technologies in healthcare systems. There were no previous specific recommendations to conduct such analyses in Brazil. This paper reviews BIA methods for health technologies and proposes BIA guidelines for the public and private Brazilian healthcare system. The following recommendations were made: adopt the budget administrator's perspective; use a timeframe of 1 to 5 years; compare reference and alternative scenarios; consider the technology's rate of incorporation; estimate the target population by either an epidemiological approach or measured demand; consider restrictions on technologies' indication or factors that increase the demand for them; consider direct and averted costs; do not adjust for inflation or discounts; preferably, integrate information on a spreadsheet; calculate the incremental budget impact between scenarios; and summarize information in a budget impact report.

    To report additional mediation findings from a descriptive cross sectional study to examine if nurses' perceptions of the impact of healthcare information technology on their practice mediates the relationship between electronic nursing care reminder use and missed nursing care. The study used a descriptive design. The sample (N = 165) was composed of registered nurses working on acute care hospital units. The sample was obtained from a large teaching hospital in Southeast Michigan in the fall of 2012. All eligible nursing units (n = 19) were included. The MISSCARE Survey, Nursing Care Reminders Usage Survey, and the Impact of Healthcare Information Technology Scale were used to collect data to test for mediation. Mediation was tested using the method described by Baron and Kenny. Multiple regression equations were used to analyze the data to determine if mediation occurred between the variables. Missed nursing care, the outcome variable, was regressed on the predictor variable, reminder usage, and the mediator variable impact of technology on nursing practice. The impact of healthcare information technology (IHIT) on nursing practice negatively affected missed nursing care (t = -4.12, p information technology mediates the relationship between nursing care reminder use and missed nursing care. The findings are beneficial to the advancement of healthcare technology in that designers of healthcare information technology systems need to keep in mind that perceptions regarding impacts of the technology will influence usage. Many times, information technology systems are not designed to match the workflow of nurses. Systems built with redundant or impertinent reminders may be ignored. System designers must study which reminders nurses find most useful and which reminders result in the best quality outcomes. © 2015 Sigma Theta Tau International.

  7. Shale gas technology innovation rate impact on economic Base Case – Scenario model benchmarks

    2015-01-01

    Highlights: • Cash flow models control which technology is affordable in emerging shale gas plays. • Impact of technology innovation on IRR can be as important as wellhead price hikes. • Cash flow models are useful for technology decisions that make shale gas plays economic. • The economic gap can be closed by appropriate technology innovation. - Abstract: Low gas wellhead prices in North America have put its shale gas industry under high competitive pressure. Rapid technology innovation can help companies to improve the economic performance of shale gas fields. Cash flow models are paramount for setting effective production and technology innovation targets to achieve positive returns on investment in all global shale gas plays. Future cash flow of a well (or cluster of wells) may either improve further or deteriorate, depending on: (1) the regional volatility in gas prices at the wellhead – which must pay for the gas resource extraction, and (2) the cost and effectiveness of the well technology used. Gas price is an externality and cannot be controlled by individual companies, but well technology cost can be reduced while improving production output. We assume two plausible scenarios for well technology innovation and model the return on investment while checking against sensitivity to gas price volatility. It appears well technology innovation – if paced fast enough – can fully redeem the negative impact of gas price decline on shale well profits, and the required rates are quantified in our sensitivity analysis

    2017-04-01

    Periods of geological changes such as super continent cycle (300-500 million years), Wilson's cycles (300-900 million years), magmatic-tectonic cycle (150-200 million years), and cycles with smaller periods (22, 100, 1000 years) lead to a basic contradiction preventing forming methodology of the study of impact of geological changes on the global and regional economies. The reason of this contradiction is the differences of theoretical and methodological aspects of the Earth science and economics such as different time scales and accuracy of geological changes. At the present the geological models cannot provide accurate estimation of time and place where geological changes (strong earthquakes, volcanos) are expected. Places of feature (not next) catastrophic events are the only thing we have known. Thus, it is impossible to use the periodicity to estimate both geological changes and their consequences. Taking into accounts these factors we suggested a collection of concepts for estimating impact of possible geological changes on regional and global economies. We illustrated our approach by example of estimating impact of Tohoku earthquake and tsunami of March 2011 on regional and global economies. Based on this example we concluded that globalization processes increase an impact of geological changes on regional and global levels. The research is supported by Russian Foundation for Basic Research (Projects No. 16-06-00056, 16-32-00019, 16-05-00263A).

    The problems of obtaining adequate pure drinking water and disposing of liquid and solid waste in the U.S Arctic, a region where virtually all water is frozen solid for much of the year, has led to unsanitary solutions. Sanitation and a safe water supply are particularly problems in rural villages. These villages are without running water and use plastic buckets for toilets. The outbreak of diseases is believed to be partially attributable to exposure to human waste and lack of sanitation. Villages with the most frequent outbreaks of disease are those in which running water is difficult to obtain. Waste is emptied into open lagoons, rivers, or onto the sea coast. It does not degrade rapidly and in addition to affecting human health, can be harmful to the fragile ecology of the Arctic and the indigenous wildlife and fish populations. Current practices for waste management and sanitation pose serious human hazards as well as threaten the environment. NASA's unique knowledge of water/wastewater treatment systems for extreme environments, identified in the Congressional Office of Technology Assessment report entitled An Alaskan Challenge: Native Villagt Sanitation, may offer practical solutions addressing the issues of safe drinking water and effective sanitation practices in rural villages. NASA's advanced life support technologies are being combined with Arctic science and engineering knowledge to address the unique needs of the remote communities of Alaska through the Advanced Life Systems for Extreme Environments (ALSEE) project. ALSEE is a collaborative effort involving the NASA, the State of Alaska, the University of Alaska, the North Slope Borough of Alaska, Ilisagvik College in Barrow and the National Science Foundation (NSF). The focus is a major issue in the State of Alaska and other areas of the Circumpolar North; the health and welfare of its people, their lives and the subsistence lifestyle in remote communities, economic opportunity, and care for the

    Selfors, A. [ed.

    1994-10-01

    This report discusses problems related to economic assessment of the environmental impacts and abatement measures in connection with energy projects. Attention is called to the necessity of assessing environmental impacts both in the form of reduced economic welfare and in the form of costs of abatement measures to reduce the impact. In recent years, several methods for valuing environmental impacts have been developed, but the project shows that few empirical studies have been carried out. The final report indicates that some important factors are very difficult to evaluate. In addition environmental impacts of energy development in Norway vary considerably from project to project. This makes it difficult to obtain a good basis for comparing environmental impacts caused by different technologies, for instance hydroelectric power versus gas power or wind versus hydroelectric power. It might be feasible however to carry out more detailed economic assessments of environmental impacts of specific projects. 33 refs., 1 fig., 4 tabs.

    Wolfe, D. W.; Hayhoe, K.

    2006-12-01

    New statistically downscaled climate modeling techniques provide an opportunity for improved regional analysis of climate change impacts on agriculture. Climate modeling outputs can often simultaneously meet the needs of those studying impacts on natural as well as managed ecosystems. Climate outputs can be used to drive existing forest or crop models, or livestock models (e.g., temperature-humidity index model predicting dairy milk production) for improved information on regional impact. High spatial resolution climate forecasts, combined with knowledge of seasonal temperatures or rainfall constraining species ranges, can be used to predict shifts in suitable habitat for invasive weeds, insects, and pathogens, as well as cash crops. Examples of climate thresholds affecting species range and species composition include: minimum winter temperature, duration of winter chilling (vernalization) hours (e.g., hours below 7.2 C), frost-free period, and frequency of high temperature stress days in summer. High resolution climate outputs can also be used to drive existing integrated pest management models predicting crop insect and disease pressure. Collectively, these analyses can be used to test hypotheses or provide insight into the impact of future climate change scenarios on species range shifts and threat from invasives, shifts in crop production zones, and timing and regional variation in economic impacts.

  16. Emission metrics for quantifying regional climate impacts of aviation

    2017-07-01

    Full Text Available This study examines the impacts of emissions from aviation in six source regions on global and regional temperatures. We consider the NOx-induced impacts on ozone and methane, aerosols and contrail-cirrus formation and calculate the global and regional emission metrics global warming potential (GWP, global temperature change potential (GTP and absolute regional temperature change potential (ARTP. The GWPs and GTPs vary by a factor of 2–4 between source regions. We find the highest aviation aerosol metric values for South Asian emissions, while contrail-cirrus metrics are higher for Europe and North America, where contrail formation is prevalent, and South America plus Africa, where the optical depth is large once contrails form. The ARTP illustrate important differences in the latitudinal patterns of radiative forcing (RF and temperature response: the temperature response in a given latitude band can be considerably stronger than suggested by the RF in that band, also emphasizing the importance of large-scale circulation impacts. To place our metrics in context, we quantify temperature change in four broad latitude bands following 1 year of emissions from present-day aviation, including CO2. Aviation over North America and Europe causes the largest net warming impact in all latitude bands, reflecting the higher air traffic activity in these regions. Contrail cirrus gives the largest warming contribution in the short term, but remain important at about 15 % of the CO2 impact in several regions even after 100 years. Our results also illustrate both the short- and long-term impacts of CO2: while CO2 becomes dominant on longer timescales, it also gives a notable warming contribution already 20 years after the emission. Our emission metrics can be further used to estimate regional temperature change under alternative aviation emission scenarios. A first evaluation of the ARTP in the context of aviation suggests that further work to account

    2009-01-01

    The diffusion of promising energy technologies in the market depends on their future energy production-cost development. When analyzing these technologies in an integrated assessment model using endogenous technological learning, the uncertainty in the assumed learning rates (LRs) plays a crucial role in the production-cost development and model outcomes. This study examines the uncertainty in LRs of some energy technologies under endogenous global learning implementation and presents a floor-cost modeling procedure to systematically regulate the uncertainty in LRs of energy technologies. The article narrates the difficulties of data assimilation, as compatible with mixed integer programming segmentations, and comprehensively presents the causes of uncertainty in LRs. This work is executed using a multi-regional and long-horizon energy system model based on 'TIMES' framework. All regions receive an economic advantage to learn in a common domain, and resource-ample regions obtain a marginal advantage for better exploitation of the learning technologies, due to a lower supply-side fuel-cost development. The lowest learning investment associated with the maximum LR mobilizes more deployment of the learning technologies. The uncertainty in LRs has an impact on the diffusion of energy technologies tested, and therefore this study scrutinizes the role of policy support for some of the technologies investigated.

    Full Text Available The study aimed to characterize the Information and Communications Technology industry utilizing online Google forms for ICT inventory and characterization to 37 respondents working in different ICT firms around Davao Region. The distribution of the firms cut across categories of enterprises, from small to large firms. Findings revealed that most of the ICT firms are new entrants of which a greater number are micro-enterprises that need government support in form of capital. In addition, the industry is predominantly populated by academic institutions that offer trainings and seminars to supplement skills and competencies needed by ICT industry. Furthermore, there is a shortage supply of ICT workers is evident and the number of ITE graduates joining the labor pool is not enough with the demand for ICT workers which will push the wages up as a result of shrinking number of workers or piracy of highly-skilled workers among ICT firms. The industry may need to strongly link with the academic institutions to imbibe corporate culture on top of the required skills of graduates. Hence a strong partnership between ICT industry and academe is indeed necessary.

    The recent announcement of commercially available high density optical storage devices will have a profound impact on the information processing industry. Just as the initial introduction of random access storage created entirely new processing strategies, optical technology will allow dramatic changes in the storage, retrieval, and dissemination of engineering drawings and other pictorial or text-based documents. Storage Technology Corporation has assumed a leading role in this arena with the introduction of the 7600 Optical Storage Subsystem, and the formation of StorageTek Integrated Systems, a subsidiary chartered to incorporate this new technology into deliverable total systems. This paper explores the impact of optical storage technology from the perspective of a leading-edge manufacturer and integrator.

    Five studies are presented which assess the impacts of global warming on physical, economic, and social systems in Canada. A study on the use of climatic change scenarios to estimate ecoclimatic impacts was carried out. These scenarios may include synthetic scenarios produced from historical data, global climate model (GCM) simulations, and hybrid scenarios. The advantages and drawbacks of various scenarios are discussed along with the criteria for selecting impact assessment models. An examination of water resources in the Great Lakes and the Saskatchewan River subbasin uses case studies of two areas that have experienced wide hydrological variations due to climatic variability in order to determine the impacts of global warming scenarios on net basin supply. Problems of developing regional models are discussed and results of projected changes in net basin supply are presented for GCM-based simulations and hypothetical warming scenarios. A study of the impacts of climate warming on transportation and the regional economy in northern Canada uses stochastic models to provide examples of how Mackenzie River barge traffic will be affected. The economic impacts of the resultant lengthened shipping season are outlined under three scenarios. The implications of climatic change on Ontario agriculture are assessed according to GCM scenarios. Results are presented for crop yields and production as well as land resource suitability. Finally, sociocultural implications of global warming on the Arctic and the Inuit are summarized, with reference to a past warming episode occurring around the year 1000. 45 refs., 4 figs., 3 tabs

    The human species has been modifying the landscape long before the development of modern agrarian techniques. Much of the land area of the conterminous United States is currently used for agricultural production. In certain regions this change in vegetative cover from its natural state may have led to local climatic change. A regional climate version of the Colorado State University Regional Atmospheric Modeling System was used to assess the impact of a natural versus current vegetation distribution on the weather and climate of July 1989. The results indicate that coherent regions of substantial changes, of both positive and negative sign, in screen height temperature, humidity, wind speed, and precipitation are a possible consequence of land use change throughout the United States. The simulated changes in the screen height quantities were closely related to changes in the vegetation parameters of albedo, roughness length, leaf area index, and fractional coverage.

    Climate change will affect one region differently from another. For that reason, the U.S. Unified Synthesis Product "Global Climate Change Impacts in the United States" broke down its assessment of climate change impacts on the country into 8 regions. Key highlights include: In the Northeast, agricultural production, including dairy, fruit, and maple syrup, will be increasingly affected as favorable climates shift northward. In the Southeast, accelerated sea-level rise and increased hurricane intensity will have serious impacts. In the Midwest, under higher emissions scenarios, significant reductions in Great Lakes water levels will impact shipping, infrastructure, beaches, and ecosystems. In the Great Plains, projected increases in temperature, evaporation, and drought frequency exacerbate concerns regarding the region's declining water resources. In the Southwest, water supplies will become increasingly scarce, calling for trade-offs among competing uses, and potentially leading to conflict. In the Northwest, salmon and other cold-water species will experience additional stresses as a result of rising water temperatures and declining summer streamflows. In Alaska, thawing permafrost damages roads, runways, water and sewer systems, and other infrastructure. And in the U.S. islands in the Caribbean and Pacific, climate changes affecting coastal and marine ecosystems will have major implications for tourism and fisheries. In addition, significant sea-level rise and storm surge will affect coastal cities and ecosystems around the nation; low-lying and subsiding areas are most vulnerable.

    IMPaCT enables comprehensive information on current NASA missions, prospective future missions, and the technologies that NASA is investing in, or considering investing in, to be accessed from a common Web-based interface. It allows dependencies to be established between missions and technology, and from this, the benefits of investing in individual technologies can be determined. The software also allows various scenarios for future missions to be explored against resource constraints, and the nominal cost and schedule of each mission to be modified in an effort to fit within a prescribed budget.

    Low impact development ( LID), as an innovative technology for stormwater management, is effective to mitigate urban flooding and to detain pollutants. This paper systemically introduced the LID technology system, and summarized the reduction effects of three typical LID facilities (i.e. , bio-retention, green roof and permeable pavement) on stormwater runoff and main pollutants in recent literature, as well as research outcomes and experiences of LID technology on model simulation, cost-benefit analysis and management system. On this basis, we analyzed the problems and limitations of current LID technology studies. Finally, some suggestions about future research directions, appropriate design and scientific management were put forth. This work intended to provide scientific basis and suggestions for widespread use and standard setting of LID technology in China by referencing overseas studies.

    Climate change and technology development can affect crop productivity in future conditions. Precise estimation of crops yield change as affected by climate and technology in the future is an effective approach for management strategies. The aim of this study was to estimate the impacts of climate change, technology improvement, CO2 enrichment, and overall impacts on wheat yield under future conditions. Wheat yield was projected for three future time periods (2020, 2050 and 2080) compared to baseline year (2011) under two scenarios of IPCC Special Report on Emission Scenarios (SRES) including SRES-A2 as regional economic scenario and SRES-B1 as global environmental scenario in Azarbaijan region (NW of Iran). A linear regression model, describing the relationship between wheat yield and historical year, was developed to investigate technology development effect. The decision support system for agro-technology transfer (DSSAT4.5) was used to evaluate the influence of climate change on wheat yield. The most positive effects were found for wheat yield as affected by technology in all studied regions. Under future climate change, the SRES projected a decrease in yield, especially in West Azarbaijan region. When the effects of elevated CO2 were considered, all regions resulted to increase in wheat yield. Considering all components effect in comparison with baseline (2011), yield increase would range from 5% to 38% across all times, scenarios and regions. According to our findings, it seems that we may expect a higher yield of wheat in NW Iran in the future if technology development continues as well as past years. (Author)

    2014-01-01

    Full Text Available In the competition for economically attractive stakeholders, regions have to implement strategies to gain and adhere those interest groups. Empirical studies concerning the migration motivations show that it is not only labor market but also soft locational factors of the social environment, nature and landscape that are of high importance: A majority of the population is willing to move or rather stay at a special place because of such soft locational factors. This study examines the impact of regional marketing projects on the development of regions from the perspectives of inhabitants and tourists as well as general attributes to measure a region’s attractiveness from the perspective of high potentials. We argue that those projects that fit to the region and its unique selling propositions contribute to positioning and building location brand value. We show that projects have a socio-economic effect on the attitude towards regions and contribute to building location brand value. An analysis of group differences shows that the project influence on the region and region attractiveness are perceived in significantly different manner depending on the knowledge level of the stakeholder group. Consequently, one should increase the awareness of marketing activities and regions and focus on soft locational factors while establishing and positioning a region brand.

    2017-09-01

    Full Text Available Aim/Purpose: The media and research have made significant noise about young people’s addictions to technology, however the American Psychological Association (APA has reserved judgment on the clinical diagnosis of technology addiction. Research to understand technology addiction is important to the future of information systems development and behavioral usage understanding. Background: Addiction implies that there is a problem from which an IS client needs to try to recover, further implying a negative impact on life. Multiple defini-tions and outcomes of addictions have been studied in the information systems discipline, with virtually no focus on quality of life of the IS client. Methodology: This research employs a survey of students at a large southwestern United States university. Measures were adopted from previously validated sources. The final sample includes 413 usable responses analyzed using PLS. Contribution: This research broadens theoretical and practical understanding of SNS IS client perceptions by relating technology addiction to a broader impact on an individual’s life. By doing so, it provides guidance on society’s understanding of frequent technology use, as well as the development of new systems that are highly used. Findings: This research indicates diminished impulse control, distraction, social influence and satisfaction are all highly correlated with technology addiction; specifically, 55% of the variance in addiction is explained by these four indicators. However, the model further shows addiction has no significant relationship with overall satisfaction of life, indicating that IS clients do not correlate the two ideas. Recommendations for Practitioners: Heavy technology use may indicate a paradigm shift in how people inter-act, instead of a concern to be addressed by the APA. Recommendation for Researchers: Research needs to clearly define technology dependence, addiction, and overuse so that there is a strong

    Coastal aquifers have been identified as particularly vulnerable to impacts on water quantity and quality due to the high density of socio-economic activities and human assets in coastal regions and to the projected rising sea levels, contributing to the process of saltwater intrusion. This paper proposes a Regional Risk Assessment (RRA) methodology integrated with a chain of numerical models to evaluate potential climate change-related impacts on coastal aquifers and linked natural and human systems (i.e., wells, river, agricultural areas, lakes, forests and semi-natural environments). The RRA methodology employs Multi Criteria Decision Analysis methods and Geographic Information Systems functionalities to integrate heterogeneous spatial data on hazard, susceptibility and risk for saltwater intrusion and groundwater level variation. The proposed approach was applied on the Esino River basin (Italy) using future climate hazard scenarios based on a chain of climate, hydrological, hydraulic and groundwater system models running at different spatial scales. Models were forced with the IPCC SRES A1B emission scenario for the period 2071-2100 over four seasons (i.e., winter, spring, summer and autumn). Results indicate that in future seasons, climate change will cause few impacts on the lower Esino River valley. Groundwater level decrease will have limited effects: agricultural areas, forests and semi-natural environments will be at risk only in a region close to the coastline which covers less than 5% of the total surface of the considered receptors; less than 3.5% of the wells will be exposed in the worst scenario. Saltwater intrusion impact in future scenarios will be restricted to a narrow region close to the coastline (only few hundred meters), and thus it is expected to have very limited effects on the Esino coastal aquifer with no consequences on the considered natural and human systems.

    Academic technology transfer in its current form began with the passage of the Bayh-Dole Act in 1980, which allowed universities to retain ownership of federally funded intellectual property. Since that time, a profession has evolved that has transformed how inventions arising in universities are treated, resulting in significant impact to US society. While there have been a number of articles highlighting benefits of technology transfer, now, more than at any other time since the Bayh-Dole Act was passed, the profession and the impacts of this groundbreaking legislation have come under intense scrutiny. This article serves as an examination of the many positive benefits and evolution, both financial and intrinsic, provided by academic invention and technology transfer, summarized in Table 1.

    Nowadays students were born in a world of continuous evolution of technology. Technology is part of their daily life inside and outside their professional studies. One of the most important discoveries when it comes to technology is the internet which provides today the possibility for students to have access to all types of information and resources which are very useful in their studies activities. Therefore, in our paper we ask a very natural question: which is the place of technology in the university studies? Moreover: What part does technology play in teaching Maritime subjects? And: Which is the impact of technology in maritime teaching? Our intention is to go into more specific details on this subject, as in trying to exemplify our observations based on our own experience in teaching in Constanta Maritime University. Further on, we intend to discuss how the so called “smart” technologies came into occupying a very important place in the daily activities of our students forcing trainers to cope with this phenomenon in order to improve their teaching activities and even their relation (communication) with their students. We chose to develop this subject because everybody needs to be aware of the huge differences between generations of students. Previous generations used to require and enjoy studying from the traditional paper resources, while present generations do not even visit the libraries anymore. This is why university lecturers need to adapt their teaching methods, teaching tools and study materials to their students’ needs and of course to the evolution of technology.

  6. Ensemble-based Regional Climate Prediction: Political Impacts

    2008-12-01

    Accurate forecasts of regional climate, including temperature and precipitation, have significant implications for human activities, not just economically but socially. Sub Saharan Africa is a region that has displayed an exceptional propensity for devastating civil wars. Recent research in political economy has revealed a strong statistical relationship between year to year fluctuations in precipitation and civil conflict in this region in the 1980s and 1990s. To investigate how climate change may modify the regional risk of civil conflict in the future requires a probabilistic regional forecast that explicitly accounts for the community's uncertainty in the evolution of rainfall under anthropogenic forcing. We approach the regional climate prediction aspect of this question through the application of a recently demonstrated method called generalized scalar prediction (Leroy et al. 2009), which predicts arbitrary scalar quantities of the climate system. This prediction method can predict change in any variable or linear combination of variables of the climate system averaged over a wide range spatial scales, from regional to hemispheric to global. Generalized scalar prediction utilizes an ensemble of model predictions to represent the community's uncertainty range in climate modeling in combination with a timeseries of any type of observational data that exhibits sensitivity to the scalar of interest. It is not necessary to prioritize models in deriving with the final prediction. We present the results of the application of generalized scalar prediction for regional forecasts of temperature and precipitation and Sub Saharan Africa. We utilize the climate predictions along with the established statistical relationship between year-to-year rainfall variability in Sub Saharan Africa to investigate the potential impact of climate change on civil conflict within that region.

  7. The Influencing Factors, Regional Difference and Temporal Variation of Industrial Technology Innovation: Evidence with the FOA-GRNN Model

    2018-01-01

    Full Text Available Technology innovation is a motivating force for sustainable development. The recognition and measurement of influencing factors are a basic prerequisite of technology innovation research. In response to the gaps and shortages of existing theories and methods, this paper builds the impact indicators of technology innovation, the proposed FOA-GRNN model, and analyzes the influencing factors, regional differences and temporal variations of technology innovation based on industrial above-scale enterprises of 31 provinces in China from 2008 to 2015. The empirical results show that innovation investment is a determinant of technology innovation in China, and is more and more significant; meanwhile a wide gap of innovation resource between Eastern China and Western China exists. In general, the enterprise scale has a negative effect: with enlargement of enterprise in China, the innovation efficiency of enterprise will decline, while the effect has regional disparity, with positive influence in Central and Western China, and negative influence in Eastern China. Government support has negative effects on technology innovation: indirect equity investment contributes more to technology innovation than direct fund support. Innovation environment has positive and weak effects on technology innovation, but it is the biggest obstacle in Western China, and the innovation environment in China has improved continuously. This paper provides new evidence that can shine some light on determining the factors affecting technology innovation, and also presents a novel approach, which comprises characteristics of nonlinear function approximation, high accuracy and a small sample.

    Aviation emissions impact surface air quality at multiple scales—from near-airport pollution peaks associated with airport landing and take off (LTO) emissions, to intercontinental pollution attributable to aircraft cruise emissions. Previous studies have quantified aviation’s air quality impacts around a specific airport, in a specific region, or at the global scale. However, no study has assessed the air quality and human health impacts of aviation, capturing effects on all aforementioned scales. This study uses a multi-scale modeling approach to quantify and monetize the air quality impact of civil aviation emissions, approximating effects of aircraft plume dynamics-related local dispersion (˜1 km), near-airport dispersion (˜10 km), regional (˜1000 km) and global (˜10 000 km) scale chemistry and transport. We use concentration-response functions to estimate premature deaths due to population exposure to aviation-attributable PM2.5 and ozone, finding that aviation emissions cause ˜16 000 (90% CI: 8300-24 000) premature deaths per year. Of these, LTO emissions contribute a quarter. Our estimate shows that premature deaths due to long-term exposure to aviation-attributable PM2.5 and O3 lead to costs of ˜21 bn per year. We compare these costs to other societal costs of aviation and find that they are on the same order of magnitude as global aviation-attributable climate costs, and one order of magnitude larger than aviation-attributable accident and noise costs.

    Climate change has been predicted to adversely impact regional air quality with resulting health effects. Here a regional air quality model and a technology analysis tool are used to assess the additional emission reductions required and associated costs to offset impacts of climate change on air quality. Analysis is done for six regions and five major cities in the continental United States. Future climate is taken from a global climate model simulation for 2049-2051 using the Intergovernmental Panel on Climate Change (IPCC) A1B emission scenario, and emission inventories are the same as current ones to assess impacts of climate change alone on air quality and control expenses. On the basis of the IPCC A1B emission scenario and current control technologies, least-cost sets of emission reductions for simultaneously offsetting impacts of climate change on regionally averaged 4th highest daily maximum 8-hr average ozone and yearly averaged PM2.5 (particulate matter [PM] with an aerodynamic diameter less than 2.5 microm) for the six regions examined are predicted to range from $36 million (1999$) yr(-1) in the Southeast to $5.5 billion yr(-1) in the Northeast. However, control costs to offset climate-related pollutant increases in urban areas can be greater than the regional costs because of the locally exacerbated ozone levels. An annual cost of $4.1 billion is required for offsetting climate-induced air quality impairment in 2049-2051 in the five cities alone. Overall, an annual cost of $9.3 billion is estimated for offsetting climate change impacts on air quality for the six regions and five cities examined. Much of the additional expense is to reduce increased levels of ozone. Additional control costs for offsetting the impacts everywhere in the United States could be larger than the estimates in this study. This study shows that additional emission controls and associated costs for offsetting climate impacts could significantly increase currently estimated

    Climate change can influence the U.S. electricity sector in many ways, the nature of which can be shaped by energy and environmental policy choices. Changing temperatures affect electricity demand largely through heating and cooling needs, and temperatures also affect generation and transmission system performance. Altered precipitation patterns affect the regional and seasonal distribution of surface water runoff, which changes hydropower operation and thermal cooling water availability. The extent to which these stimuli influence U.S. power sector operation and planning will depend to some extent on whether or not proactive policies are enacted to mitigate these impacts. Mitigation policies such as CO2 emissions limits or technology restrictions can change the makeup of the electricity system while reducing the extent of climate change itself. We use the National Renewable Energy Laboratory's Regional Energy Deployment System (ReEDS), a U.S. electric sector capacity expansion model, to explore electric sector evolution through 2050 under alternative climate and policy assumptions. The model endogenously represents climate impacts on load, power system performance, cooling water availability, and hydropower, allowing internally consistent system responses to climate change along with projected technology, market, and policy conditions. We compare climate impacts across 5 global circulation models for a 8.5 W/m2 representative concentration pathway (RCP) without a climate mitigation policy and a 4.5 W/m2 RCP with climate mitigation. Climate drivers affect the capacity and generation mix at the national and regional levels, with relative growth of wind, solar, and natural gas-based technologies depending on local electricity system characteristics. These differences affect regional economic impacts, measured here as changes to electricity price and system costs. Mitigation policy reduces the economic and system impacts of climate change largely by moderating

    New technologies can make previously invisible phenomena visible. Nowhere is this more obvious than in the field of light microscopy. Beginning with the observation of "animalcules" by Antonie van Leeuwenhoek, when he figured out how to achieve high magnification by shaping lenses, microscopy has advanced to this day by a continued march of discoveries driven by technical innovations. Recent advances in single-molecule-based technologies have achieved unprecedented resolution, and were the basis of the Nobel prize in Chemistry in 2014. In this article, we focus on developments in camera technologies and associated image processing that have been a major driver of technical innovations in light microscopy. We describe five types of developments in camera technology: video-based analog contrast enhancement, charge-coupled devices (CCDs), intensified sensors, electron multiplying gain, and scientific complementary metal-oxide-semiconductor cameras, which, together, have had major impacts in light microscopy. © 2016 Marine Biological Laboratory.

    Technology integration studies were made to examine the impact of emerging technologies on fighter aircraft. The technologies examined included advances in aerodynamics, controls, structures, propulsion, and systems and were those which appeared capable of being ready for application by the turn of the century. A primary impetus behind large increases in figher capability will be the rapid increase in fighter engine thrust-to-weight ratio. High thrust-weight engines, integrated with other advanced and emerging technologies, can result in small extremely maneuverable fighter aircraft that have thrust-weight ratios of 1.4+ and weight one-half as much as today's fighters. Future fighter aircraft requirements are likely to include a turn capability in excess of 7g's throughout much of the maneuver envelope, post-stall maneuverability, STOVL or VTOL, and a single engine for low cost.

  18. Determining long-term regional erosion rates using impact craters

    Science.gov (United States)

    Hergarten, Stefan; Kenkmann, Thomas

    2015-04-01

    More than 300,000 impact craters have been found on Mars, while the surface of Moon's highlands is even saturated with craters. In contrast, only 184 impact craters have been confirmed on Earth so far with only 125 of them exposed at the surface. The spatial distribution of these impact craters is highly inhomogeneous. Beside the large variation in the age of the crust, consumption of craters by erosion and burial by sediments are the main actors being responsible for the quite small and inhomogeneous crater record. In this study we present a novel approach to infer long-term average erosion rates at regional scales from the terrestrial crater inventory. The basic idea behind this approach is a dynamic equilibrium between the production of new craters and their consumption by erosion. It is assumed that each crater remains detectable until the total erosion after the impact exceeds a characteristic depth depending on the crater's diameter. Combining this model with the terrestrial crater production rate, i.e., the number of craters per unit area and time as a function of their diameter, allows for a prediction of the expected number of craters in a given region as a function of the erosion rate. Using the real crater inventory, this relationship can be inverted to determine the regional long-term erosion rate and its statistical uncertainty. A limitation by the finite age of the crust can also be taken into account. Applying the method to the Colorado Plateau and the Deccan Traps, both being regions with a distinct geological history, yields erosion rates in excellent agreement with those obtained by other, more laborious methods. However, these rates are formally exposed to large statistical uncertainties due to the small number of impact craters. As higher crater densities are related to lower erosion rates, smaller statistical errors can be expected when large regions in old parts of the crust are considered. Very low long-term erosion rates of less than 4

    International Nuclear Information System (INIS)

    1991-01-01

    To date, much of the attention given to global warming in scientific research as well as in policy development has focused on the global picture. International negotiations and agreements to stabilize, and eventually reduce, greenhouse gas emissions are very important. By themselves, however, they are not sufficient to address global warming. Regional strategies are also needed. They can help reduce greenhouse gas emissions, and they will be the most effective way to mitigate the consequences of global warming. Adaptive strategies must respond to local and regional conditions. In many countries, subnational jurisdictions such as states and provinces or community organizations can already take effective actions without direction from their national government or waiting for international agreements. An important factor in defining regional approaches is the disparate consequences of climate change for developed and developing areas. Different strategies will also be needed for industrial and agricultural regions. Wealthy industrial regions may be better able to develop capital-intensive, adaptive infrastructure than regions with fewer discretionary resources where people are more vulnerable to the vagaries of weather patterns. On the other hand, regions that rely on indigenous knowledge and local resources may be better equipped to make incremental adaptations and more willing to modify life-styles. Ultimately, all climate change effects are experienced in specific places and effective response depends upon local action. We recognize that individual localities cannot solve a problem of global proportions by acting alone. However, a regional strategy can supplement international and national action and be the focal point for addressing risks in the unique social and economic context of a particular area. These meetings discussions dealt with the impacts and implications of climate change on such things as agriculture, forestry, and policy

    Following approximately 10 years from the beginning of Iran's national Health Technology Assessment (HTA) programme, the present study aims to evaluate its success by examining the impact of HTA and identifying the determinant factors leading to the implementation of HTA report results. The triangulation method was employed herein. HTA reports were initially identified and their impact and determinant factors were then examined from the perspectives of both researchers (by preparing a questionnaire according to the Payback model and sending it to HTA principle investigators) and stakeholders (semi-structured interviews held with each HTA stakeholder). Simultaneously, the quality of the HTA reports was examined with relevant critical appraisal checklists. The impact of 19 equipment technologies and four pharmaceutical technologies were assessed in this study. Twenty researchers replied (response rate, 86.96%) to the questionnaire on the impact of HTA reports from the researcher's perspective. To assess the impact of HTA reports from the stakeholder's perspective, seven policy-makers were chosen and interviewed as the main target audience. The most common step taken to disseminate the results of the HTA projects was publication. Conducting the HTA had taught researchers and their colleagues' new skills and had facilitated the securing of research grants from other organisations. Most reports had used the systematic review method but the relevant details had been scarcely presented regarding outcomes, costs and analysis. The greatest impact of HTA reports on decision-making had been on policy-makers providing and allocating finances. Barriers in stewardship, identification and prioritisation of topics, performance and dissemination of HTA results were the main barriers of implementing HTAs. In most aspects, the status of HTA impact reports need improvement. Thus far, the barriers and facilitators of the HTA programme in Iran have been investigated in other studies

    Biomass burning is a major regional and global driver for atmospheric composition. Its effects in regional and global climate are very significant, but still difficult to assess. Even in large urban areas in Latin America such as Mexico City, Sao Paulo and Santiago, and in developed areas such as Paris and Californian cities it is possible to observe significant biomass burning effects air quality. The wood burning components as well as inner city and vicinities burning if agricultural residues impact heavily the concentration of organic aerosol, carbon monoxide and ozone in urban areas. Regionally, regions such as Amazonia and Central America show large plumes of smoke that extend their impact over continental areas, with changes in the radiation balance, air quality and climate. The deforestation rate in Amazonia have dropped strongly from 27,000 Km2 in 2004 to 6,200 Km2 in 2011, a very significant reduction, but this reduction was not observed in Africa and Southeast Asia. Health effects of biomass burning emissions are very significant, and observed in several key regions. Remote sensing techniques for fire detection have progressed significantly and long time series (10-15 years) are now feasible. The black carbon associated with biomass burning has important impacts in formation and development of clouds in Amazonia and other regions. The organic component of biomass burning emissions scatter light and increase diffuse radiation that alters carbon uptake in large regions of Amazonia and certainly other forested areas. Increase of up to 30% in carbon uptake associated with biomass burning emissions was observed in Amazonia, as part of the LBA Experiment. New analytical methods that quantify the absorption angstrom exponent of biomass burning and fossil fuel black carbon (BC) can differentiate BC from different burning sources. In addition, the hygroscopic properties of particles with a core shell of BC coated with organic compounds can be measured and shows

    Delta regions are attractive for high intensity agriculture due to the availability of rich sedimentary soils and of fresh water. Many of the world's tropical deltas support high population densities which are reliant on irrigated agriculture. However environmental changes such as sea level rise, tidal inundation and reduced river flows have reduced the quantity and quality of water available for successful agriculture. Additionally, anthropogenic influences such as the over abstraction of ground water and the increased use of low quality water from river inlets has resulted in the accumulation of salts in the soils which diminishes crop productivity. Communities based in these regions are usually reliant on the same water for drinking and cooking because surface water is frequently contaminated by commercial and urban pollution. The expansion of shallow tube well systems for drinking water and agricultural use over the last few decades has resulted in mobilisation of salinity in the coastal and estuarine fringes. Sustainable development in delta regions is becoming constrained by water salinity. However salinity is often studied as an independent issue by specialists working in the fields of agriculture, community water supply and groundwater. The lack of interaction between these disciplines often results in corrective actions being applied to one sector without fully assessing the effects of these actions on other sectors. This paper describes a framework for indentifying the causes and impacts of salinity in delta regions based on the source-pathway-receptor framework. It uses examples and scenarios from the Ganges-Brahmaputra-Meghna delta in Bangladesh together with field measurements and observations made in vulnerable coastal communities. The paper demonstrates the importance of creating an holistic understanding of the development and management of water resources to reduce the impact of salinity in fresh water in delta regions.

    During its four years in orbit around Mercury, the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft's X-ray Spectrometer revealed a large geochemical terrane in the northern hemisphere that hosts the highest Mg/Si, S/Si, Ca/Si, and Fe/Si and lowest Al/Si ratios on the planet. Correlations with low topography, thin crust, and a sharp northern topographic boundary led to the proposal that this high-Mg region is the remnant of an ancient, highly degraded impact basin. Here we use a numerical modeling approach to explore the feasibility of this hypothesis and evaluate the results against multiple mission-wide data sets and resulting maps from MESSENGER. We find that an 3000 km diameter impact basin easily exhumes Mg-rich mantle material but that the amount of subsequent modification required to hide basin structure is incompatible with the strength of the geochemical anomaly, which is also present in maps of Gamma Ray and Neutron Spectrometer data. Consequently, the high-Mg region is more likely to be the product of high-temperature volcanism sourced from a chemically heterogeneous mantle than the remains of a large impact event.Plain Language SummaryDuring its four years in orbit around Mercury, chemical measurements from the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft revealed a large region of unusual composition relative to the rest of the planet. Its elevated magnesium abundance, in particular, led to the name of the "high-magnesium region" (HMR). High magnesium abundance in rock can be an indicator of its origin, such as high-temperature volcanism. Although the HMR covers approximately 15% of Mercury's surface, its origin is not obvious. It does roughly correspond to a depression with thin crust, which previously led to the hypothesis that it is an ancient impact crater that was large enough to excavate mantle material, which, in rocky planets, is rich in magnesium relative to their

  10. Renewable biomass energy: Understanding regional scale environmental impacts

    Energy Technology Data Exchange (ETDEWEB)

    Graham, R.L.; Downing, M.

    1993-12-31

    If biomass energy is to become a significant component of the US energy sector, millions of acres of farmland must be converted to energy crops. The environmental implications of this change in land use must be quantitatively evaluated. The land use changes will be largely driven by economic considerations. Farmers will grow energy crops when it is profitable to do so. Thus, models which purport to predict environmental changes induced by energy crop production must take into account those economic features which will influence land use change. In this paper, we present an approach for projecting the probable environmental impacts of growing energy crops at the regional scale. The approach takes into account both economic and environmental factors. We demonstrate the approach by analyzing, at a county-level the probable impact of switchgrass production on erosion, evapotranspiration, nitrate in runoff, and phosphorous fertilizer use in multi-county subregions within the Tennessee Valley Authority (TVA) region. Our results show that the adoption of switchgrass production will have different impacts in each subregion as a result of differences in the initial land use and soil conditions in the subregions. Erosion, evapotranspiration, and nitrate in runoff are projected to decrease in both subregions as switchgrass displaces the current crops. Phosphorous fertilizer applications are likely to increase in one subregion and decrease in the other due to initial differences in the types of conventional crops grown in each subregion. Overall these changes portend an improvement in water quality in the subregions with the increasing adoption of switchgrass.

    2009-12-01

    The Earth Impact Effects Program (www.lpl.arizona.edu/impacteffects) is a popular web-based calculator for estimating the regional environmental consequences of a comet or asteroid impact on Earth. It is widely used, both by inquisitive members of the public as an educational device and by scientists as a simple research tool. It applies a variety of scaling laws, based on theory, nuclear explosion test data, observations from terrestrial and extraterrestrial craters and the results of small-scale impact experiments and numerical modelling, to quantify the principal hazards that might affect the people, buildings and landscape in the vicinity of an impact. The program requires six inputs: impactor diameter, impactor density, impact velocity prior to atmospheric entry, impact angle, and the target type (sedimentary rock, crystalline rock, or a water layer above rock), as well as the distance from the impact at which the environmental effects are to be calculated. The program includes simple algorithms for estimating the fate of the impactor during atmospheric traverse, the thermal radiation emitted by the impact plume (fireball) and the intensity of seismic shaking. The program also approximates various dimensions of the impact crater and ejecta deposit, as well as estimating the severity of the air blast in both crater-forming and airburst impacts. We illustrate the strengths and limitations of the program by comparing its predictions (where possible) against known impacts, such as Carancas, Peru (2007); Tunguska, Siberia (1908); Barringer (Meteor) crater, Arizona (ca 49 ka). These tests demonstrate that, while adequate for large impactors, the simple approximation of atmospheric entry in the original program does not properly account for the disruption and dispersal of small impactors as they traverse Earth's atmosphere. We describe recent improvements to the calculator to better describe atmospheric entry of small meteors; the consequences of oceanic impacts; and

    A set of patterns related to the impact factor of technological journals has been analyzed, with emphasis on radiation instrumentation and medical physics publications. Attention was devoted in particular to two IEEE journals, IEEE Transactions on Nuclear Science and IEEE Transactions on Medical Imaging, representative of these categories. The results are compared to a similar survey of particle physics journals. The weight of citations coming from inside the same subject area has been evaluated with respect to the amount of citations deriving from publications in external domains. A preliminary analysis hints to a significant degree of correlation between a high impact factor of some journals and a large fraction of citations originating from the same field. The results highlight the cross-disciplinary role of technological journals.

    The newly formed Chemical Institute of Canada (CIC)/Canadian Society for Chemical Engineering (CSChE) Energy Subject Division is working to develop a methodology for assessing and communicating to governments, regulators and the public the relative merits of different technologies for meeting energy demand requirements or reducing energy consumption. The focus is on developing a process that considers a broader range of issues than basic economics, or greenhouse gas (GHG) emissions. The 12 assessment criteria proposed would address five major areas of concerns including: a) how well assumptions have been tested against the scientific method over the life cycle of an energy development, b) impacts on the availability of the basic requirements for life, c) maintaining the quality of human life, d) maintaining the quality of the local environment (air, land and water), in the area where a specific technology is used, and e) considers the potential global impacts of GHG emissions.

    1999-01-01

    This article describes the different types of climate numerical models and their use to obtain scenarios for climate change due to the greenhouse gas increase. Results from global or meso-scale models are given. They illustrate the existing ways of representing climatic conditions at global and regional scales. Combined with statistical approaches based for example on the techniques of analogues, their use gives a coherent strategy going from global scale numerical simulations to the study of impacts at a local scale. In the future the increase of computer power should allow a better description of the small processes and a wider range of impact studies on natural ecosystems and various economic sectors. The results of these studies will be very useful to define a coherent policy in response to observed or predicted climate changes. (author)

    Many factors go into appropriate recommendation and use of hearing assistive technology (HAT). The aging auditory system presents with its own complications and intricacies; there are many types of age-related hearing loss, and it is possible that the underlying cause of hearing loss can significantly impact the recommendations and performance with HATs. The audiologist should take into consideration peripheral and central auditory function when selecting HATs for the aging adult population as well as when selecting appropriate types of technology including personal sound amplification products, hearing aids, cochlear implants, and other assistive technology. The cognitive ability of the patient plays a central role in the recommendations of HAT. It is possible that the use of HATs could mitigate some of the effects of cognitive decline and thus should be considered as early as possible. Assessment of ability and appropriate recommendations are crucial to consistent use of HAT devices.

    Full Text Available The paper presents the environmental impact created through the introduction of introducing new technologies in transportation domain. New electric vehicles are considered zero-emission vehicles (ZEV. However, electricity produced in power plants is still predominantly based on fossil fuel usage (required for recharge electric vehicle batteries and thus directly affects the quantity of pollutant emissions and greenhouse gases (CO2, NOx and SOx. Given the structure of EU-wide energy sources used for electricity generation, the potential pollutant emissions stemming from these energy sources, related to energy consumption of an electric vehicle, was determined under the projected environmental impact of specific market penetration of electric vehicles. In addition to the overall impact at the EU level, were identified the countries for which the use of electric vehicles is (or not feasible in terms of reaching the lower values ​​of future emissions compared to the present and future European standards.

    For the implementation of high-energy impulse technologies of mechanical shock methods of secondary rock destruction, electromagnetic machines of vibro-impact action are of particular interest. Linear synchronous electromagnetic impact machine designs as a part of progress trend are considered where the head reciprocal motion is synchronized with 50 Hz power source pulses frequency applied to a winding or a system of windings. On the basis of identified differences of the head forced mechanical oscillation processes, merits and demerits of the work cycles of single or two-winding synchronous machine design variants are analyzed. Synchronous electromagnetic machines of a new design and principles of their control in a work cycle are presented. The specific half-wave interleaving of voltages applied to the windings allows reducing current amplitude and the influence of the impact drive on the power grid. To improve forced oscillation mode stability and precision, the new engineering solutions improving machines performances and exploitation conditions are proposed.

    2016-01-01

    This paper presents a new perspective that there is a double-threshold effect in terms of the technology gap existing in the foreign direct investment (FDI) technology spillover process in different regional Chinese industrial sectors. In this paper, a double-threshold regression model was established to examine the relation between the threshold effect of the technology gap and technology spillover. Based on the provincial panel data of Chinese industrial sectors from 2000 to 2011, the empirical results reveal that there are two threshold values, which are 1.254 and 2.163, in terms of the technology gap in the industrial sector in eastern China. There are also two threshold values in both the central and western industrial sector, which are 1.516, 2.694 and 1.635, 2.714, respectively. The technology spillover is a decreasing function of the technology gap in both the eastern and western industrial sectors, but a concave curve function of the technology gap is in the central industrial sectors. Furthermore, the FDI technology spillover has increased gradually in recent years. Based on the empirical results, suggestions were proposed to elucidate the introduction of the FDI and the improvement in the industrial added value in different regions of China.

    Irrigation increases agricultural productivity, but it also stresses water resources (Huffaker and Hamilton 2007). Drought and the potential for drier conditions resulting from climate change could strain water supplies in landscapes where human populations rely on finite groundwater resources for drinking, agriculture, energy, and industry (IPCC 2007). For instance, in the North American Great Plains, rowcrops are utilized for livestock feed, food, and bioenergy production (Cassman and Liska 2007), and a large portion is irrigated with groundwater from the High Plains aquifer system (McGuire 2011). Under projected future climatic conditions, greater crop water use requirements and diminished groundwater recharge rates could make rowcrop irrigation less feasible in some areas (Rosenberg et al. 1999; Sophocleous 2005). The Rainwater Basin region of south central Nebraska, United States, is an intensively farmed and irrigated Great Plains landscape dominated by corn (Zea mays L.) and soybean (Glycine max L.) production (Bishop and Vrtiska 2008). Ten starch-based ethanol plants currently service the region, producing ethanol from corn grain (figure 1). In this study, we explore the potential of switchgrass (Panicum virgatum L.), a drought-tolerant alternative bioenergy feedstock, to impact regional annual groundwater withdrawals for irrigation under warmer and drier future conditions. Although our research context is specific to the Rainwater Basin and surrounding North American Great Plains, we believe the broader research question is internationally pertinent and hope that this study simulates similar research in other areas.

    Full Text Available Current world affairs show that the post-industrial stage of development of all mature world powers’ economies is followed by creation of a new development paradigm, which is based on the economy of knowledge, science achievements, innovations, global information and communication systems, and which leads to innovative economy formation. In the context of the national innovation economy formation in the Russian Federation, prerequisites are created for integrating the efforts of business, science and education representatives to develop, produce and market high-tech products which have significant economic or social potential. And this is not only the task announced by the Russian government, but also a natural process in the country’s economy, which contributes to the increase in the integration participants’ efficiency. The result of such integrated interaction of education, science and business consists in a synergistic effect through formation of an interactive cooperation model that involves the active use of combined knowledge, ideas, technologies and other resources during innovative projects implementation. At the same time, integration processes are diverse, complex and occur in each case taking into account the integrating parties’ activity specifics. Within this framework, the goal of the research is to characterize the impact of the education, science and business integration process, on the national technological initiative implementation in the country on the whole and to study the integrating experience of these entities at the regional level. In the course of the research, the stages of the Russian national innovation economy formation process have been studied; the role of education, science and business in the National Technological Initiative implementation has been characterized; it’s been proved that educational institutions are the key link in the integration process in the chain “education – science

    To prioritize climate adaptation strategies, there is a need for quantitative and systematic regional-level assessments which are comparable across multiple climatic hazard regimes. Assessing which countries in a region are most vulnerable to climate change requires analysis of multiple climatic hazards including: droughts, floods, extreme temperature as well as rainfall and sea-level rise. These five climatic hazards, along with population densities were modelled using GIS which enabled a summary of associated human exposure and agriculture losses. A combined index based on hazard, exposure and adaptive capacity is introduced to identify areas of extreme risks. The analysis results in population climate hazard exposure defined as the relative likelihood that a person in a given location was exposed to a given climate-hazard event in a given period of time. The study presents a detailed and coherent approach to fine-scale climate hazard mapping and identification of risks areas for the regions of South Asia that, for the first time, combines the following unique features: (a) methodological consistency across different climate-related hazards, (b) assessment of total exposure on population and agricultural losses, (c) regional-level spatial coverage, and (d) development of customized tools using ArcGIS toolbox that allow assessment of changes in exposure over time and easy replacement of existing datasets with a newly released or superior datasets. The resulting maps enable comparison of the most vulnerable regions in South Asia to climate-related hazards and is among the most urgent of policy needs. Subnational areas (regions/districts/provinces) most vulnerable to climate change impacts in South Asia are documented. The approach involves overlaying climate hazard maps, sensitivity maps, and adaptive capacity maps following the vulnerability assessment framework of the United Nations' Intergovernmental Panel on Climate Change (IPCC).

    This version of the Impact of Sector Energy Technologies (ImSET) model represents the ''next generation'' of the previously developed Visual Basic model (ImBUILD 2.0) that was developed in 2003 to estimate the macroeconomic impacts of energy-efficient technology in buildings. More specifically, a special-purpose version of the 1997 benchmark national Input-Output (I-O) model was designed specifically to estimate the national employment and income effects of the deployment of Office of Energy Efficiency and Renewable Energy (EERE) -developed energy-saving technologies. In comparison with the previous versions of the model, this version allows for more complete and automated analysis of the essential features of energy efficiency investments in buildings, industry, transportation, and the electric power sectors. This version also incorporates improvements in the treatment of operations and maintenance costs, and improves the treatment of financing of investment options. ImSET is also easier to use than extant macroeconomic simulation models and incorporates information developed by each of the EERE offices as part of the requirements of the Government Performance and Results Act.

    Cogeneration is one of the most powerful technologies for reduction of environmental pollution along with renewable energies. At the Kyoto Conference cogeneration has been identified as being the most important measure for reducing emissions of greenhouse effect gases. It has also been mentioned that cogeneration has a potential of reducing pollution with about 180 million tones per year. In order to promote new cogeneration technologies and evaluate the existing ones it is necessary to know and to be able to quantify in economical terms the environmental issues. When comparing different cogeneration technologies: steam turbine (TA), gas turbine (TG), internal combustion engine (MT), in order to choose the best one, the final decision implies an economic factor, which is even more important if it includes the environmental issues. The environmental impact of different cogeneration technologies is quantified using different criteria: depletion of non-renewable natural resources, eutrofisation, greenhouse effect, acidification etc. Environmental analysis using these criteria can be made using the 'impact with impact' methodology or the global one. The results of such an analysis cannot be quantified economically directly. Therefore there is a need of internalisation of ecological effects within the costs of produced energy: electricity and heat. In the energy production sector the externalizations represent the indirect effects on the environment. They can be materialised within different types of environmental impact: - Different buildings of mines, power plants etc; - Fuel losses during transportation and processing; - Effect of emissions in the air, water and soil. Introduction of the environmental impact costs in the energy price is called internalisation and it can be made using the direct and indirect methods. The paper discusses aspects regarding the emissions of cogeneration systems, the eco-taxes - method of 'internalisation' of environmental

    Advanced thermal treatment technologies utilizing pyrolysis or gasification, as well as a combined approach, are introduced as sustainable methods to treat wastes in Singapore. Eight different technologies are evaluated: pyrolysis-gasification of MSW; pyrolysis of MSW; thermal cracking gasification of granulated MSW; combined pyrolysis, gasification and oxidation of MSW; steam gasification of wood; circulating fluidized bed (CFB) gasification of organic wastes; gasification of RDF; and the gasification of tyres. Life cycle assessment is carried out to determine the environmental impacts of the various waste conversion systems including global warming potential, acidification potential, terrestrial eutrophication and ozone photochemical formation. The normalization and weighting results, calculated according to Singapore national emission inventories, showed that the two highest impacts are from thermal cracking gasification of granulated MSW and the gasification of RDF; and the least are from the steam gasification of wood and the pyrolysis-gasification of MSW. A simplified life cycle cost comparison showed that the two most costs-effective waste conversion systems are the CFB gasification of organic waste and the combined pyrolysis, gasification and oxidation of MSW. The least favorable - highest environmental impact as well as highest costs - are the thermal cracking gasification of granulated MSW and the gasification of tyres.

    Possible impacts of energy technologies on agriculture are evaluated, and some of the available simulation models that can be used for predictive purposes are identified. An overview of energy technologies and impacts on the environment is presented to provide a framework for the commentary on the models. Coal combustion is shown to have major impacts on the environment and these will continue into the next century according to current Department of Energy projections. Air pollution effects will thus remain as the major impacts on crop ecosystems. Two hundred reports were evaluated, representing a wide range of models increasing in complexity from mathematical functions (fitted to data) through parametric models (which represent phenomena without describing the mechanisms) to mechanistic models (based on physical, chemical, and physiological principles). Many models were viewed as suitable for adaptation to technology assessment through the incorporation of representative dose-response relationships. It is clear that in many cases available models cannot be taken and directly applied in technology assessment. Very few models of air pollutant-crop interactions were identified, even though there is a considerable data base of pollutant effects on crops.

    The North American continent has the largest tar-sand resources in the world with approximately 1.3x10 12 barrels of oil-equivalent in Canada and 3.6x10 10 barrels of oil-equivalent in the USA. Petroleum from these deposits can significantly increase crude oil supplies. However, no single oil-recovery process is likely to be applicable to all tar-sand deposits, which differ considerably in their geophysical and chemical properties. The authors have estimated the risk of occurrence of significant unfavourable environmental, health and safety impacts associated with tar-sand technologies. These estimates were made from information related to typical emerging surface (above ground) and in-situ (underground) tar-sand oil-recovery processes. Both types of processes are being developed for use on tar-sand deposits in the USA and may also be applicable to deposits in other countries. First, the levels of pollutant emissions affecting land, air and water were determined from data related to current US field experiments involving surface processes (including retort and solvent extraction methods), and in-situ techniques (including combustion and steam-injection methods). Next, these data were extrapolated to determine pollutant levels expected from conceptual commercial facilities producing 20,000 barrels per day. These estimates predict the nature and magnitude of environmental, health and safety impacts. The likelihood of occurrence of these impacts was then assessed. Experience from other industries, including information concerning health and ecosystem damage from air pollutants, measurements of groundwater transport of organic pollutants, and the effectiveness of environmental control technologies, was used to make this assessment, from which it was concluded that certain adverse effects are more likely to occur than others. These effects are discussed in the paper and ordered for surface and in-situ technologies according to their likelihood of occurrence

    ARPEGE general circulation model simulations were dynamically downscaled by The Weather Research and Forecasting Model (WRF) for the study of climate change and its impact on grapevine growth in Burgundy region in France by the mid twenty-first century. Two time periods were selected: 1970-1979 and 2031-2040. The WRF model driven by ERA-INTERIM reanalysis data was validated against in situ surface temperature observations. The daily maximum and minimum surface temperature (T{sub max} and T{sub min}) were simulated by the WRF model at 8 x 8 km horizontal resolution. The averaged daily T{sub max} for each month during 1970-1979 have good agreement with observations, the averaged daily T{sub min} have a warm bias about 1-2 K. The daily T{sub max} and T{sub min} for each month (domain averaged) during 2031-2040 show a general increase. The largest increment ({proportional_to}3 K) was found in summer. The smallest increments (<1 K) were found in spring and fall. The spatial distribution of temperature increment shows a strong meridional gradient, high in south in summer, reversing in winter. The resulting potential warming rate in summer is equivalent to 4.7 K/century under the IPCC A2 emission scenario. The dynamically downscaled T{sub max} and T{sub min} were used to simulate the grape (Pinot noir grape variety) flowering and veraison dates. For 2031-2040, the projected dates are 8 and 12 days earlier than those during 1970-1979, respectively. The simulated hot days increase more than 50% in the two principal grapevine regions. They show strong impact on Pinot noir development. (orig.)

    Past studies have shown that the use of coarse resolution SST products such as from the real-time global (RTG) SST analysis[1] or other coarse resolution once-a-day products do not properly portray the diurnal variability of fluxes of heat and moisture from the ocean that drive the formation of low level clouds and precipitation over the ocean. For example, the use of high resolution MODIS SST composite [2] to initialize the Advanced Research Weather Research and Forecast (WRF) (ARW) [3] has been shown to improve the prediction of sensible weather parameters in coastal regions [4][5}. In an extend study, [6] compared the MODIS SST composite product to the RTG SST analysis and evaluated forecast differences for a 6 month period from March through August 2007 over the Florida coastal regions. In a comparison to buoy data, they found that that the MODIS SST composites reduced the bias and standard deviation over that of the RTG data. These improvements led to significant changes in the initial and forecasted heat fluxes and the resulting surface temperature fields, wind patterns, and cloud distributions. They also showed that the MODIS composite SST product, produced for the Terra and Aqua satellite overpass times, captured a component of the diurnal cycle in SSTs not represented in the RTG or other one-a-day SST analyses. Failure to properly incorporate these effects in the WRF initialization cycle led to temperature biases in the resulting short term forecasts. The forecast impact was limited in some situations however, due to composite product inaccuracies brought about by data latency during periods of long-term cloud cover. This paper focuses on the forecast impact of an enhanced MODIS/AMSR-E composite SST product designed to reduce inaccuracies due data latency in the MODIS only composite product.

  3. A Market Model for Evaluating Technologies That Impact Critical-Material Intensity

    2016-07-01

    A recent Critical Materials Strategy report highlighted the supply chain risk associated with neodymium and dysprosium, which are used in the manufacturing of neodymium-iron-boron permanent magnets (PM). In response, the Critical Materials Institute is developing innovative strategies to increase and diversify primary production, develop substitutes, reduce material intensity and recycle critical materials. Our goal in this paper is to propose an economic model to quantify the impact of one of these strategies, material intensity reduction. Technologies that reduce material intensity impact the economics of magnet manufacturing in multiple ways because of: (1) the lower quantity of critical material required per unit PM, (2) more efficient use of limited supply, and (3) the potential impact on manufacturing cost. However, the net benefit of these technologies to a magnet manufacturer is an outcome of an internal production decision subject to market demand characteristics, availability and resource constraints. Our contribution in this paper shows how a manufacturer's production economics moves from a region of being supply-constrained, to a region enabling the market optimal production quantity, to a region being constrained by resources other than critical materials, as the critical material intensity changes. Key insights for engineers and material scientists are: (1) material intensity reduction can have a significant market impact, (2) benefits to manufacturers are non-linear in the material intensity reduction, (3) there exists a threshold value for material intensity reduction that can be calculated for any target PM application, and (4) there is value for new intellectual property (IP) when existing manufacturing technology is IP-protected.

    Full Text Available Due to the emergence of what in Indonesian is called industri rekaman daerah ‘Indonesian regional recording industries’, which has developed significantly since the 1980s, many regional recording companies have been established in Indonesia. As a consequence, more and more aspects of Indonesian regional culture have appeared in commercial recordings. Nowadays commercial cassettes and Video Compact Discs (VCDs of regional pop and oral literature genres from different ethnic groups are being produced and distributed in provincial and regency towns, even those situated far from the Indonesian capital of Jakarta. Considering the extensive mediation and commodification of ethnic cultures in Indonesia, this paper investigates the impact of the rise of a regional recording industry on Minangkabau oral literature in West Sumatra. Focussing on recordings of some Minangkabau traditional verbal art genres on commercial cassettes and VCDs by West Sumatran recording companies, this paper attempts to examine the way in which Minangkabau traditional verbal art performers have engaged with electronic communication, and how this shapes technological and commercial conditions for ethnic art and performance in one modernizing society in regional Indonesia.

    Water management in the Western USA is challenged by the demands of an increased population, ecological needs and changing values for water use, and a broadening of variability in climate, which together have created physical limits on water availability. The management of scarce water resources in this region is strictly constrained by the current legal structure (prior appropriation water rights) on one hand, and on the other assisted by the development of new, efficient water delivery and application technologies. Therefore, critical components for a complete understanding of the hydrological landscape include the institutions governing water rights, the technologies used for the highly water consumptive agricultural sector, and the role institutions and technologies play in altering when and where water is used and consumed by humans or reserved for the environment. To explore the sensitivities of water availability within the human-physical system, we present a method to incorporate water rights allocated under the prior appropriation doctrine for the western U.S. into the University of New Hampshire macro-scale Water Balance Model to capture the essential structure of these rights and their impacts on different economic sectors in Idaho and across the US West. In addition to legal structures, new irrigation technologies also alter the efficiency and timing of water use. We assess the impacts of a variety of technologies for both the delivery of water to the agricultural fields and the application methods for bringing water to the crops on consumptive and non-consumptive agricultural water use. We explore the impacts relative to natural climate variability, investigate the role that return flows from different agricultural technologies have on regional water balance, and examine the sensitivity of the entire system to extremes such as extended drought. These methods are sufficiently generalizable to be used by other hydrological models.

The reference EDGARv4.3.1 emissions include observed and reported changes in activity data, fuel consumption and air pollution abatement technologies over the past 4 decades, combined with Tier 1 and region-specific Tier 2 emission factors. Two further retrospective scenarios assess the interplay of policy and industry. The highest emission STAG_TECH scenario assesses the impact of the technology and end-of-pipe reduction measures in the European Union, by considering historical fuel consumption, along with a stagnation of technology with constant emission factors since 1970, and assuming no further abatement measures and improvement imposed by European emission standards. The lowest emission STAG_ENERGY scenario evaluates the impact of increased fuel consumption by considering unchanged energy consumption since the year 1970, but assuming the technological development, end-of-pipe reductions, fuel mix and energy efficiency of 2010. Our scenario analysis focuses on the three most important and most regulated sectors (power generation, manufacturing industry and road transport, which are subject to multi-pollutant European Union Air Quality regulations. Stagnation of technology and air pollution reduction measures at 1970 levels would have led to 129 % (or factor 2.3 higher SO2, 71 % higher NOx and 69 % higher PM2.5 emissions in Europe (EU27, demonstrating the large

    Full Text Available Abstract Background Disaster-related mortality is a growing public health concern in the African Region. These deaths are hypothesized to have a significantly negative effect on per capita gross domestic product (GDP. The objective of this study was to estimate the loss in GDP attributable to natural and technological disaster-related mortality in the WHO African Region. Methods The impact of disaster-related mortality on GDP was estimated using double-log econometric model and cross-sectional data on various Member States in the WHO African Region. The analysis was based on 45 of the 46 countries in the Region. The data was obtained from various UNDP and World Bank publications. Results The coefficients for capital (K, educational enrolment (EN, life expectancy (LE and exports (X had a positive sign; while imports (M and disaster mortality (DS were found to impact negatively on GDP. The above-mentioned explanatory variables were found to have a statistically significant effect on GDP at 5% level in a t-distribution test. Disaster mortality of a single person was found to reduce GDP by US$0.01828. Conclusions We have demonstrated that disaster-related mortality has a significant negative effect on GDP. Thus, as policy-makers strive to increase GDP through capital investment, export promotion and increased educational enrolment, they should always keep in mind that investments made in the strengthening of national capacity to mitigate the effects of national disasters expeditiously and effectively will yield significant economic returns.

  11. The regional income and employment impacts of nuclear power stations

    1982-01-01

    This paper attempts quantitatively to assess the income and employment impacts associated with two nuclear establishments in Scotland: the United Kingdom Atomic Energy Authority (U.K.A.E.A.) nuclear power establishment at Dounreay in Caithness and the South of Scotland Electricity Board (S.S.E.B.) nuclear power station presently under construction at Torness in the Lothian region. The model used is a basic Keynesian income multiplier model refined to allow detailed analysis of income and employment impacts at a local level. As used in this study it allows the identification of the increase in income and the associated increase in employment relating to the siting of a nuclear power plant in a particular locality. Results are given. The employment multipliers are estimated to be in the range 1.236 to 1.535 for Dounreay and 1.294 to 1.675 for the operational phase of the Torness plant. It is concluded that although the absolute income increases in the respective subregions are significant, compared to the total annual expenditure of the establishments these figures indicate high leakage from the subregions.

    2010-10-01

    Full Text Available Orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. Management and prognosis depend on the composition and location of the foreign body and whether there is secondary infection. Metallic objects and glass are the most frequently encountered and well-tolerated, whereas organic foreign bodies can elicit an inflammatory reaction and lead to serious complications. Despite the modern imaging methods, it is often difficult to identify and locate organic intraorbital foreign bodies. This paper presents a review of nine cases of impacted foreign bodies in the orbital region and discusses the diagnosis and treatment of this kind of injury. The following data were collected: age, gender, etiology of injury, occurrence of fracture, anatomical location of fracture, type of object, signs and symptoms, type of imaging exam used, approach, transoperative complication and occurrence of death. Foreign body injuries in the orbital region can be treated with a combination of clinical suspicion, basic knowledge and diagnostic tests and depend on the skill and experience of the surgeon, thereby decreasing the surgical risk of iatrogenic injury in relation to the inherent risk of retaining an organic intraorbital foreign body.

  13. Assessing climate change impacts on water resources in remote mountain regions

    Buytaert, Wouter; De Bièvre, Bert

    2013-04-01

    From a water resources perspective, remote mountain regions are often considered as a basket case. They are often regions where poverty is often interlocked with multiple threats to water supply, data scarcity, and high uncertainties. In these environments, it is paramount to generate locally relevant knowledge about water resources and how they impact local livelihoods. This is often problematic. Existing environmental data collection tends to be geographically biased towards more densely populated regions, and prioritized towards strategic economic activities. Data may also be locked behind institutional and technological barriers. These issues create a "knowledge trap" for data-poor regions, which is especially acute in remote and hard-to-reach mountain regions. We present lessons learned from a decade of water resources research in remote mountain regions of the Andes, Africa and South Asia. We review the entire tool chain of assessing climate change impacts on water resources, including the interrogation and downscaling of global circulation models, translating climate variables in water availability and access, and assessing local vulnerability. In global circulation models, mountain regions often stand out as regions of high uncertainties and lack of agreement of future trends. This is partly a technical artifact because of the different resolution and representation of mountain topography, but it also highlights fundamental uncertainties in climate impacts on mountain climate. This problem also affects downscaling efforts, because regional climate models should be run in very high spatial resolution to resolve local gradients, which is computationally very expensive. At the same time statistical downscaling methods may fail to find significant relations between local climate properties and synoptic processes. Further uncertainties are introduced when downscaled climate variables such as precipitation and temperature are to be translated in hydrologically

    Full Text Available The world coastal environment is made of diversified landforms and are also potentially vulnerable to climate variability, delta sinking, extreme events and anthropogenic interferences. Sustainable management of coastal resources and transforming quality ecosystem services to future generation are the goals of Integrated Coastal Zone Management (ICZM. Geographical homogenous unit are the basic implementation locus and back bone of these kinds of integrated management strategy and activities. However, coastal zone management projects in developing world using use arbitrary land-ward and sea-ward boundaries from physical reference as unit of management. The oversimplified fixed distance approaches are not able to map the spatial and temporal changes in coastal systems. The spatio-temporal variations of coastal systems are configured in geomorphic landforms and further that work on interaction between natural forces and anthropogenic inputs. The present research work is an attempt to present a simplified method of regionalization geomorphic landforms using geospatial platforms for delineating Orissa coast into smaller homogenous geographic unit as reference point for future management. Geomorphic landforms are reconstructed using Enhanced Thematic Mapper Plus (ETM+ imagery, Survey of India topomaps, field survey and Digital Elevation Model data at geographic information system (GIS plat form. Seventy geomorphic features covering an area of 5033.64 km2 were identified and further, regionalized into five homogenous geographic units. The need of time is to recognize unsustainable coastal systems in these homogenous geographic units by fine tuning development parameters and also same time allowing coastal systems to adapt naturally to any kind of variability. Although, the methodology applied to Orissa for delineation homogenous geographic area but it can be replicated to any coast in world.

    2013-12-01

    Images of the Tyre feature obtained by the Galileo spacecraft's Solid State Imager (SSI) at ~170 m/pixel show concentric graben and multiple secondary craters surrounding a central rough-textured circular region, indicating an impact origin. Only crosscut by two double ridges and a large fracture, the crater is young relative to the surrounding terrain. The crater and its surroundings were mapped by Kadel et al. (2000), who also interpreted the geological history of the region. We have remapped the Tyre area for the specific purpose of creating a product that can be used for detailed comparison with 6 km/pixel Galileo Near-Infrared Mapping Spectrometer (NIMS) data. The combined SSI and NIMS product will be used to determine variations in composition among different units using linear mixture modeling employing cryogenic laboratory reference spectra, a technique that has been successfully implemented elsewhere on Europa by e.g., Shirley et al. (2010). The major difference between our mapping results and those of Kadel et al. is that we subdivide some of the units, in order to better compare them with NIMS pixels in the next (future) phase of the study. We use an orthographic projection centered at 34 N, 146 W, and construct a geologic map that extends from 25 N to 42 N and 153 W to 133 W. We identify a number of units, subunits and structural features on the basis of relative albedo and morphology. The units are grouped into six categories: Crater materials, chaos, ridges, bands, pre-impact background terrains, and indeterminate features. Many of these units are consistent with those found in the Kadel et al. study, but we find a number of bands and chaos-related materials in the background ridged plains, that have not been mapped elsewhere. These are of a sufficient size to be relevant to our future compositional analysis. We find three types of chaos (compared to two from the previous study), which are primarily concentrated in the south of the study region. Type

    Full Text Available The paper shows the process of modeling the integrated map “Scheme of the ecological and economic regionalization of the territory of the Russian Federation on the basis of the mineral and raw materials base of natural adsorbents” using GIS technologies. The map is based on three main groups of indicators: natural, economic and environmental. The ecological content of the map is characterized by indicators that are potential or actual sources of pollutant release into the environment (nuclear power plants, nuclear reactors, radioactive waste storage and disposal sites, nuclear test sites, industrial enterprises, railways, operating and under construction oil pipelines, hydrocarbon fields, etc.. The economic component of the map is the reserves estimated by the indicators of study and development, the relationship to the subsoil fund and forecast resources. The natural group of indicators is represented by the mineral and raw material base of natural adsorbents (fields and objects of forecast resources that can be used to prevent harmful emissions and for the ecological and economic rehabilitation of contaminated areas. Based on the analysis of cartographic data, the ecological and economic areas of the territorial distribution of man-caused environmental impacts and the presence of adsorption raw materials are identified. As an example, a description is given of the ecological and economic model of the regionalization of the Privolzhsky Federal District using the GIS “Mineral resource base of natural adsorbents of Russia” developed at the Federal State Unitary Enterprise TsNIIgeolnerud.

    Technology is urgently needed to clean up contamination by volatile organic compounds at United States Department of Energy (DOE) sites. In many cases, however, existing technology is too slow, inefficient, or expensive. The record of technology development is, in some cases, similarly disappointing. Remediation technologies developed at great expense and evaluated piecemeal over long periods have not been deployed because, in the end, the public judged them ineffective or unacceptable. The need for successful methods of remediation is too great and resources too limited to continue with ineffective technology evaluation. In order to make good decisions about which technologies to deploy, remedial project managers need to know stakeholders' requirements for the performance of proposed technologies. Expanding stakeholder involvement regionally identifies the concerns of a broad range of stakeholders at and DOE sites throughout the West -- issues that must be taken into account if technologies are to be accepted for wide deployment

    2016-01-01

    For long-duration space missions outside of Earth orbit, reliability considerations will drive higher levels of redundancy and/or on-board spares for life support equipment. Component scaling will be a critical element in minimizing overall launch mass while maintaining an acceptable level of system reliability. Building on an earlier reliability study (AIAA 2012-3491), this paper considers the impact of alternative scaling approaches, including the design of technology assemblies and their individual components to maximum, nominal, survival, or other fractional requirements. The optimal level of life support system closure is evaluated for deep-space missions of varying duration using equivalent system mass (ESM) as the comparative basis. Reliability impacts are included in ESM by estimating the number of component spares required to meet a target system reliability. Common cause failures are included in the analysis. ISS and ISS-derived life support technologies are considered along with selected alternatives. This study focusses on minimizing launch mass, which may be enabling for deep-space missions.

    The purpose of this paper is to study a medication distribution technology's (MDT) impact on medication errors reported in public nursing homes in Québec Province. The work was carried out in six nursing homes (800 patients). Medication error data were collected from nursing staff through a voluntary reporting process before and after MDT was implemented. The errors were analysed using: totals errors; medication error type; severity and patient consequences. A statistical analysis verified whether there was a significant difference between the variables before and after introducing MDT. The results show that the MDT detected medication errors. The authors' analysis also indicates that errors are detected more rapidly resulting in less severe consequences for patients. MDT is a step towards safer and more efficient medication processes. Our findings should convince healthcare administrators to implement technology such as electronic prescriber or bar code medication administration systems to improve medication processes and to provide better healthcare to patients. Few studies have been carried out in long-term healthcare facilities such as nursing homes. The authors' study extends what is known about MDT's impact on medication errors in nursing homes.

    Full Text Available Abstract The fourth industrial revolution stimulates the advances of science and technology, in which the Internet of Things (IoT and its supporting technologies serve as backbones for Cyber-Physical Systems (CPS and smart machines are used as the promoters to optimize production chains. Such advancement goes beyond the organizational and territorial boundaries, comprising agility, intelligence, and networking. This scenario triggers governmental efforts that aim at defining guidelines and standards. The speed and complexity of the transition to the new digitalization era in a globalized environment, however, does not yet allow a common and coordinated understanding of the impacts of the actions undertaken in different countries and regions. The aim of this paper, therefore, is to bridge this gap through a systematic literature review that identifies the most influential public policies and evaluates their existing differences. This cross-country/region comparison provides a worldwide panorama of public policies' durations, main objectives, available funding, areas for action, focused manufacturing sectors, and prioritized technologies. Findings of this review can be used as the basis to analyse the position of a country against the existing challenges imposed towards its own industrial infrastructure and also to coordinate its public policies.

    Windows play a significant role in commercial buildings targeting the goal of net zero energy. This report summarizes research methodology and findings in evaluating the energy impact of windows technologies for commercial buildings. The large office prototypical building, chosen from the DOE commercial building benchmarks, was used as the baseline model which met the prescriptive requirements of ASHRAE Standard 90.1-2004. The building simulations were performed with EnergyPlus and TMY3 weather data for five typical US climates to calculate the energy savings potentials of six windows technologies when compared with the ASHRAE 90.1-2004 baseline windows. The six windows cover existing, new, and emerging technologies, including ASHRAE 189.1 baseline windows, triple pane low-e windows, clear and tinted double pane highly insulating low-e windows, electrochromic (EC) windows, and highly insulating EC windows representing the hypothetically feasible optimum windows. The existing stocks based on average commercial windows sales are included in the analysis for benchmarking purposes.

    The article is devoted to the study of the impact of the information economy on the formation of the middle class. The paper identifies factors contributing to the increase in the share of the middle class in the transition to the information economy. The positive synergetic influence of telecommunication technologies on the formation of the middle class is considered through a possibility of using virtual spaces for labor and educational activities, a possibility of obtaining high returns in the form of dividends on intellectual capital, a qualitative change in the structure of needs, an access to new types of information services, etc. Authors develop a complex model of research of the middle class in the information economy, differing from those available using an expanded list of criteria. In addition to such widely used criteria as income level, level of education and self-identification, the criterion "degree of involvement in the information society" was introduced. The study substantiates that the transition to the information economy made an access to information and communication technologies one of the most significant criteria for social differentiation of society. On the basis of the model, an econometric estimate of the middle class has been carried out, which makes it possible to reveal the share of the middle class in modern society, dynamics of its development, as well as multicollinearity between spending on education, the Gini coefficient, access to information and telecommunication technologies and the size of the middle class.

    To employ an experimental model of opioid-induced bowel dysfunction in healthy human volunteers, and evaluate the impact ofopioid treatment compared to placebo on gastrointestinal (GI) symptoms and motility assessed by questionnaires and regional GItransit times using the 3-dimensional (3D)-Transit system. Twenty-five healthy males were randomly assigned to oxycodone or placebo for 5 days in a double blind, crossover design. AdverseGI effects were measured with the bowel function index, gastrointestinal symptom rating scale, patient assessment of constipationsymptom questionnaire, and Bristol stool form scale. Regional GI transit times were determined using the 3D-Transit system, and segmental transit times in the colon were determined using a custom Matlab(®) graphical user interface. GI symptom scores increased significantly across all applied GI questionnaires during opioid treatment. Oxycodone increased median total GI transit time from 22.2 to 43.9 hours (P transit times in the cecum and ascending colon from 5.7 to 9.9 hours (P = 0.012), rectosigmoid colon transit from 2.7 to 9.0 hours (P = 0.044), and colorectal transit time from 18.6 to 38.6 hours (P= 0.001). No associations between questionnaire scores and segmental transit times were detected. Self-assessed GI adverse effects and increased GI transit times in different segments were induced during oxycodone treatment. This detailed information about segmental changes in motility has great potential for future interventional head-to-head trials of different laxative regimes for prevention and treatment of constipation.

    This review provides current information on the production of ethanol from lignocellulosic biomass, with the main focus on relationships between process design and efficiency, expressed as ethanol concentration, yield and productivity. In spite of unquestionable advantages of lignocellulosic biomass as a feedstock for ethanol production (availability, price, non-competitiveness with food, waste material), many technological bottlenecks hinder its wide industrial application and competitiveness with 1st generation ethanol production. Among the main technological challenges are the recalcitrant structure of the material, and thus the need for extensive pretreatment (usually physico-chemical followed by enzymatic hydrolysis) to yield fermentable sugars, and a relatively low concentration of monosaccharides in the medium that hinder the achievement of ethanol concentrations comparable with those obtained using 1st generation feedstocks (e.g. corn or molasses). The presence of both pentose and hexose sugars in the fermentation broth, the price of cellulolytic enzymes, and the presence of toxic compounds that can inhibit cellulolytic enzymes and microbial producers of ethanol are major issues. In this review, different process configurations of the main technological steps (enzymatic hydrolysis, fermentation of hexose/and or pentose sugars) are discussed and their efficiencies are compared. The main features, benefits and drawbacks of simultaneous saccharification and fermentation (SSF), simultaneous saccharification and fermentation with delayed inoculation (dSSF), consolidated bioprocesses (CBP) combining production of cellulolytic enzymes, hydrolysis of biomass and fermentation into one step, together with an approach combining utilization of both pentose and hexose sugars are discussed and compared with separate hydrolysis and fermentation (SHF) processes. The impact of individual technological steps on final process efficiency is emphasized and the potential for use

    2009-01-01

    With rapid economic development, higher income levels, urbanization and other socio-economic drivers, people's lifestyles in China have changed remarkably over the last 50 years. This paper uses the IPAT model (where I = Impact representing CO 2 emissions, P = Population, A = Affluence, and T = emission intensity) to analyze how these main drivers contributed to the growth of CO 2 emissions over this time period. Affluence or lifestyle change has been variously recognized as one of the key factors contributing to CO 2 emissions. Through comparative analysis of the development of five regions in China, we trace lifestyle changes since the foundation of the People's Republic of China (PRC) in 1949 until 2002. We find that household consumption across the five regions follows similar trajectories, driven by changes in income and the increasing availability of goods and services, although significant differences still exist between and within regions due to differential policies in China and different possibilities for social mobility. There are considerable differences between the southeast and northwest and between urban and rural areas. We also found that technological improvements have not been able to fully compensate for the increase of emissions due to population growth and increasing wealth, which is also in line with results from other studies. Finally, this paper emphasizes that developing countries such as China, which is home to 22% of the world population and a growing middle class, and which is on a fast track to modernization, need to ensure that people's lifestyles are changing towards more sustainable ways of living. China has been investing heavily in infrastructure and thus creating the emissions of tomorrow. Thus investing, for example, in public transport and low energy building today will help reduce emissions in the future and will support more sustainable lifestyles. (author)

A number of regions are supporting demonstration projects and building networks among regional stakeholders to strengthen their engagement in H2FC technology. In this article, we...... will analyse regions that are highly engaged in H2FC activity, based on three indicators: existing hydrogen infrastructure and production sites, general innovativeness and the presence of industrial clusters with relevance for H2FC. Our finding is that regions with high activity in H2FC development are also...

    2009-12-10

    On April 15, 2008, the Department of Energy (DOE) issued a Funding Opportunity Announcement for Advanced Water Power Projects which included a Topic Area for Marine and Hydrokinetic Renewable Energy Market Acceleration Projects. Within this Topic Area, DOE identified potential navigational impacts of marine and hydrokinetic renewable energy technologies and measures to prevent adverse impacts on navigation as a sub-topic area. DOE defines marine and hydrokinetic technologies as those capable of utilizing one or more of the following resource categories for energy generation: ocean waves; tides or ocean currents; free flowing water in rivers or streams; and energy generation from the differentials in ocean temperature. PCCI was awarded Cooperative Agreement DE-FC36-08GO18177 from the DOE to identify the potential navigational impacts and mitigation measures for marine hydrokinetic technologies, as summarized herein. The contract also required cooperation with the U.S. Coast Guard (USCG) and two recipients of awards (Pacific Energy Ventures and reVision) in a sub-topic area to develop a protocol to identify streamlined, best-siting practices. Over the period of this contract, PCCI and our sub-consultants, David Basco, Ph.D., and Neil Rondorf of Science Applications International Corporation, met with USCG headquarters personnel, with U.S. Army Corps of Engineers headquarters and regional personnel, with U.S. Navy regional personnel and other ocean users in order to develop an understanding of existing practices for the identification of navigational impacts that might occur during construction, operation, maintenance, and decommissioning. At these same meetings, “standard” and potential mitigation measures were discussed so that guidance could be prepared for project developers. Concurrently, PCCI reviewed navigation guidance published by the USCG and international community. This report summarizes the results of this effort, provides guidance in the form of a

    The new type of climate impact models has recently come into existence. Unlike conventional models, they take into account the probabilistic nature of climatic projections and small-scale spatial variability of permafrost parameters. In this study we describe the new stochastic permafrost modeling methodology and present the predictive results obtained for the Northern Eurasia under the ensemble climatic projection for the mid-21st century. Changes in permafrost are very illustrative of the impacts of global warming. It underlies about 22.8 million square km or 24% of the land area in the Northern Hemisphere and largely controls the state of the environment and socio-economical development in the northern lands. Observed and projected for the future warming is more pronounced in high latitudes, and there are indications that climatic change has already affected permafrost leading to deeper seasonal thawing and disappearance of the frozen ground in many locations. Particular concerns are associated with environmental and economical risks due to the damage of constructions, and with potential enhancement of the global warming through emission of greenhouse gases from thawing permafrost. Comprehensive permafrost projections are needed to predict such processes. We developed new type of stochastic model, which operates with the probability distribution functions of the parameters characterizing the state of permafrost. Air temperature, precipitation, snow depth, as well as vegetation and soil properties contribute to the variability of these parameters in space and over time, which is taken into account in the calculations of the statistical ensemble representing potential states of permafrost under the prescribed conditions. The model requires appropriate climatic and environmental data characterizing baseline or projected for the future conditions. Four gridded sets of climatic parameters constructed through spatial interpolation of meteorological observations and

  16. Environmental impacts of energy facilities: fuel cell technology compared with coal and conventional gas technology

    Seip, Knut L.; Thorstensen, Bernt; Wang, Hagbarth

    We compare the environmental side effects of power plants based on fuel cell technology with the side effects of conventional electric power plants based on coal and natural gas. The environmental impact of a solid oxide fuel cell (SOFC) plant is very much less than that of a coal-fired plant (a factor of {1}/{300} for air pollution and a factor of {1}/{5} for water pollution). Compared with a conventional gas plant, impact is reduced by between 50 and 98%. Damage to cultural monuments and buildings is negligible from a fuel cell plant. Socioeconomic negative impacts are reduced by about 30% relative to conventional gas plants (aesthetics and noise) whereas employment is unaltered. Impact on health and safety is greatly reduced compared with that from coal-fired plants and is about 70% of that from conventional gas plants. Preliminary results suggest that society's willingness to pay (WTP) for clean air, and thereby better health, matches the cost of installing emission-reducing equipment on conventional power plants. There is probably an additional WTP for other benefits (e.g., decreased risk of global warming). Thus, the utility of very small emissions, lower CO 2 discharges, and other benefits from SOFC generators may compensate for the increased cost incurred in producing electricity by SOFC generators.

    1994-01-01

    The current status of small-scale specimen technology in Charpy impact testing for ferritic steels is presented, with emphasis on the effect of the notch dimensions (notch depth, notch root radius and notch angle) on the upper shelf energy (USE) and ductile-to-brittle transition temperature (DBTT). The USE for miniaturized specimens, normalized by Bb 2 or (Bb) 3/2 (B is the specimen thickness, b the ligament size), is essentially independent of notch geometry and has a linear relationship with the USE of full size specimens, regardless of irradiation and alloy conditions. The DBTT of miniaturized specimens depends strongly on the notch dimensions; this dependence of the DBTT decreases as the DBTT of full size specimens increase due to neutron irradiation or thermal aging. These results may be useful in determining the USE and DBTT for full size specimens from those for miniaturized specimens. ((orig.))

    This article provides a general framework for understanding the use of information and communication technology in education and discusses the impact of computer usage on students' health and development. Potential beneficial and harmful effects of computer use by children are discussed. Early epidemiological and laboratory studies have indicated that children are at least of similar risk of developing musculoskeletal and vision problems as adults, and musculoskeletal and visual health problems developed in childhood are likely to persist into adulthood. This article, therefore, aims to provide a reflection on the deficits of existing policy and recommendations for child-specific guidelines in computer use. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Quantitative assessments of system reliability and equivalent system mass (ESM) were made for different life support architectures based primarily on International Space Station technologies. The analysis was applied to a one-year deep-space mission. System reliability was increased by adding redundancy and spares, which added to the ESM. Results were thus obtained allowing a comparison of the ESM for each architecture at equivalent levels of reliability. Although the analysis contains numerous simplifications and uncertainties, the results suggest that achieving necessary reliabilities for deep-space missions will add substantially to the life support ESM and could influence the optimal degree of life support closure. Approaches for reducing reliability impacts were investigated and are discussed.

    The development of educational support materials by NASA's Microgravity Science and Applications Division is discussed in the light of two programs. Descriptions of the inception and application possibilities are given for the Microgravity-Science Teacher's Guide and the program of Undergraduate Research Opportunities in Microgravity Science and Technology. The guide is intended to introduce students to the principles and research efforts related to microgravity, and the undergraduate program is intended to reinforce interest in the space program. The use of computers and electronic communications is shown to be an important catalyst for the educational efforts. It is suggested that student and teacher access to these programs be enhanced so that they can have a broader impact on the educational development of space-related knowledge.

    As part of measuring the impact of government programs on improving the energy efficiency of the nation`s building stock, the Department of Energy Office of Building Technology, State and Community Programs (BTS) is interested in assessing the economic impacts of its portfolio of programs, specifically the potential impact on national employment and income. This assessment is being done for the first time in FY99 as a supplement to the Government Performance and Results Act (GPRA--formerly, Quality Metrics) estimates of primary energy savings and environmental and direct financial benefits of the BTS programs. The programmatic needs of BTS suggest that a simple, flexible, user-friendly method is needed to derive national employment and income impacts of individual BTS programs. Therefore, BTS funded Pacific Northwest National Laboratory (PNNL) to develop a special-purpose version of the Impact Analysis for Planning (IMPLAN) national input-output model (Minnesota IMPLAN Group, Inc. 1997) specifically to estimate the employment and income effects of building energy technologies. The special-purpose version of the IMPLAN model used in this study is called ImBuild. Extensive documentation and a user`s guide are provided in Scott et al. (1998). Compared with simple economic multiplier approaches, such as the published multipliers from the Department of Commerce Regional Input-Output Modeling System (RIMS 2), ImBuild allows for more complete and automated analysis of the economic impacts of energy efficiency investments in buildings. ImBuild is also easier to use than existing macroeconomic simulation models. In this report, the authors use the ImBuild model to calculate the impact of all 32 BTS programs reported in the BTS GPRA Metrics Estimates, FY99 Budget Request, December 19, 1997.

  4. The Study of Impacts of Water Transferring From Wet Regions To Dry Regions In Iran

    Science.gov (United States)

    Motiee-Homayoun, Dr.; Ghomashchi, Dr.

    Iran, with a very diverse ecology and different climate has been classified as a dry- semidry region. Iran's annual average of rain-fall is about 250 mm, while this figure is more than 1000 mm in north and less than 100 mm in the south of the country. Overall, Iran's water resources are low. Rapid population growth, economic growth together with significant urban development, in recent decades, has led to underestimate high demands for water. Therefore, water shortage has been considered more obviously. Such an important scare is rather serious in central and eastern regions of the country. This problem has been determined as a serious challenge for Iran's government and national water authorities, in particular. Although, drinking water supply is only 6 percent of total water resources, due to direct socio-political impacts, drinking water supply, in both quality and quantity, is more serious and important than agricultural water demands. Accordingly, for the following reasons: 1) Desperation and diversity of geographical conditions of urban areas 2) Low access to underground water 3) Inadequate quality surface water supply Difficulties and the costs of supplying urban water in Iran have been sharply increased. Presently, due to unconstrained consuming underground water and negative balance in most under ground resources of the country, more specifically in central and eastern regions, water supply from groundwater resources is very risky and misleading. Furthermore, other reason such as rapid urban population growth and changes in people's every day life and their consumption patterns increase both water consumption and waste water in the circumstances of inadequate sewage systems, make a vast source of pollution for water resources. Due to the influence of extended See (Salty) water, in southern provinces, near to Persian Gulf, accessibility to fresh water is rather difficult and in many cases only after tens of kilometers far from the see, fresh water could be

    Full Text Available The introduction of translation technologies, especially translation memory software, has had a significant impact on both the translator’s professional practice and the target text itself. Apart from the fact that he or she must translate in a non-linear fashion due to the design of translation memory systems, the translator is now called upon to increase output and, in many cases, recycle what has already been translated by others. As a result, the translator, used to having full control over his or her text, is in some regards losing control over the translation process, which brings him or her to reflect on the quality of the final product and, in turn, on the transformations the field of specialized translation is undergoing. In this paper, I will present the results of an important ethnographic study conducted in three Canadian translation environments. I will focus mostly on the effects translation technologies and newly implemented practices have had on the quality of specialized texts destined for the Canadian market, where most of the specialized texts produced in French are in fact translations. Special attention will be given to the comments made by specialized translators during semi-directed interviews.

  6. The impact of environmental policy on economic indicators. Moving from global to sectoral and regional perspectives

    2013-07-01

    In recent times, environmental, energy and climate policies have gained tremendously in importance. Not least, this is due to the latest research findings related to climate change and the resulting growing environmental awareness among people. However, policy approaches to combat environmental pollution and climate change differ both in their intention and in their economic impacts. For instance, command-and-control instruments such as performance or technology standards have different implications than market-based mechanisms such as permit trading of greenhouse gas emissions. Furthermore, sectoral and regional characteristics play an important role when implementing and assessing policy measures. This applies both to the attainability of the targets and to the available instruments. The present doctoral thesis addresses this point and analyzes in several essays different policy instruments and their economic effects from global, regional and sectoral perspectives. In this respect, it deals with various, often very heterogeneous question: How are specific policy types implemented in different countries? What is the CO2 abatement potential in specific regions and sectors? What policy measures can be plausibly used to exploit this potential? How can technological developments and technology-directed policy interventions contribute to improve energy efficiency? Does the promotion of certain energy sources necessarily create positive production and employment effects? To answer these and further questions, different economic methods are applied that accommodate the particular problem, where special emphasis is put on computable general equilibrium modeling. The aim of this work is to contribute to the academic and political debate on measures to combat environmental and climate problems.

    The impact of endometrial cavity fluid (ECF) on assisted reproductive technology (ART) outcomes has not been evaluated in a meta-analysis. To evaluate the impact of ECF on the outcome of ART cycles. PubMed, China Academic Journals Full-text Database, and China Doctoral/Masters Dissertations Full-text Databases were searched for reports published in any language before January 1, 2015, using relevant keywords. Studies were included if they compared the outcome of ART in women with and without ECF. Background information, participants' characteristics, and study outcomes were recorded. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the Mantel-Haenszel method. Six studies evaluating 5928 ART cycles were included. The pregnancy rate was significantly lower in the group with ECF than in the group without ECF (OR 0.74, 95% CI 0.55-0.98; P=0.03). The same association was observed if the analysis included only patients with hydrosalpinx (OR 0.36, 95% CI 0.15-0.86; P=0.02). The clinical pregnancy rate after ART is significantly lower among patients with ECF than among those without ECF. In addition, if ECF is found in patients with hydrosalpinx, ART cycles should be cancelled after oocyte retrieval. Copyright © 2015 International Federation of Gynecology and Obstetrics.

    To reduce time and cost of damage inspection, on-line impact monitoring of aircraft composite structures is needed. A digital monitor based on an array of piezoelectric transducers (PZTs) is developed to record the impact region of impacts on-line. It is small in size, lightweight and has low power consumption, but there are two problems with the impact alarm region localization method of the digital monitor at the current stage. The first one is that the accuracy rate of the impact alarm region localization is low, especially on complex composite structures. The second problem is that the area of impact alarm region is large when a large scale structure is monitored and the number of PZTs is limited which increases the time and cost of damage inspections. To solve the two problems, an impact alarm region imaging and localization method based on digital sequences and time reversal is proposed. In this method, the frequency band of impact response signals is estimated based on the digital sequences first. Then, characteristic signals of impact response signals are constructed by sinusoidal modulation signals. Finally, the phase synthesis time reversal impact imaging method is adopted to obtain the impact region image. Depending on the image, an error ellipse is generated to give out the final impact alarm region. A validation experiment is implemented on a complex composite wing box of a real aircraft. The validation results show that the accuracy rate of impact alarm region localization is approximately 100%. The area of impact alarm region can be reduced and the number of PZTs needed to cover the same impact monitoring region is reduced by more than a half. PMID:24084123

    HVIS 2005 was a clear success. The Symposium brought together nearly two hundred active researchers and students from thirteen countries around the world. The 84 papers presented at HVIS 2005 constitute an ''update'' on current research and the state-of-the-art of hypervelocity science. Combined with the over 7000 pages of technical papers from the eight previous Symposia, beginning in 1986, all published in the International Journal of Impact Engineering, the papers from HVIS 2005 add to the growing body of knowledge and the progressing state-of-the-art of hypervelocity science. It is encouraging to report that even with the limited funding resources compared to two decades ago, creativity and ingenuity in hypervelocity science are alive and well. There is considerable overlap in different disciplines that allows researchers to leverage. Experimentally, higher velocities are now available in the laboratory and are ideally suited for space applications that can be tied to both civilian (NASA) and DoD military applications. Computationally, there is considerable advancement both in computer and modeling technologies. Higher computing speeds and techniques such as parallel processing allow system level type applications to be addressed directly today, much in contrast to the situation only a few years ago. Needless to say, both experimentally and computationally, the ultimate utility will depend on the curiosity and the probing questions that will be incumbent upon the individual researcher. It is quite satisfying that over two dozen students attended the symposium. Hopefully this is indicative of a good pool of future researchers that will be needed both in the government and civilian industries. It is also gratifying to note that novel thrust areas exploring different and new material phenomenology relevant to hypervelocity impact, but a number of other applications as well, are being pursued. In conclusion, considerable progress is still being

    In October of 2003 experts involved in various aspects of homeland security from the Pacific region met to engage in a free-wheeling discussion and brainstorming (a 'fest') on the role that technology could play in winning the war on terrorism in the Pacific region. The result was a concise and relatively thorough definition of the terrorism problem in the Pacific region, emphasizing the issues unique to Island nations in the Pacific setting, along with an action plan for developing working demonstrations of advanced technological solutions to these issues. Since PacFest 2003, the maritime dimensions of the international security environment have garnered increased attention and interest. To this end, PacFest 2004 sought to identify gaps and enabling technologies for maritime domain awareness and responsive decision-making in the Asia-Pacific region. The PacFest 2004 participants concluded that the technologies and basic information building blocks exist to create a system that would enable the Pacific region government and private organizations to effectively collaborate and share their capabilities and information concerning maritime security. The proposed solution summarized in this report integrates national environments in real time, thereby enabling effective prevention and first response to natural and terrorist induced disasters through better use of national and regional investments in people, infrastructure, systems, processes and standards.

    The application of ERTS-1 imagery is rapidly increasing man's knowledge of polar regions. Products compiled from this imagery at scales of 1:250,000, 1:500,000 and 1:1,000,000 are already providing valuable information to earth scientists working in Antarctica. Significant finds detected by these bench mark products were glaciological changes, advancement in ice fronts, discovery of new geographic features, and the repositioning of nunataks, islands, and ice tongues. Tests conducted in Antarctica have proven the feasibility of tracking Navy navigation satellites to establish ground control for positioning ERTS-1 imagery in remote areas. ERTS imagery coupled with satellite geodesy shows great promise and may prove to be the most practical and cost effective way to meet the small-scale cartographic requirements of the polar science community.

    2014-01-01

    Full Text Available Mega-sport events such as Olympic Games or Football World Cup are always presented as providing the hosting nation and/or city with huge benefits. Supporters of such events quote economic, social and cultural impacts for the region as well as contributions to scientific and technological progress and innovation. obviously, they need to politically justify the impressive and growing financial investment required by organizing Olympic Games or World Cup. The article aims at looking at a quite abundant academic literature with the objectives of defining the various potential impacts and the methods used for their assessment. It concludes that there is no universal and scientifically valid model for evaluating the benefits of mega-sport events and that organizers should be very cautious when arguing in favor of deciding to host such events.

  16. Global Impacts of Long-Term Land Cover Changes Within China's Densely Populated Rural Regions

    Ellis, E. C.

    2006-12-01

    Long-term changes in land cover are usually investigated in terms of large-scale change processes such as urban expansion, deforestation and land conversion to agriculture. Yet China's densely populated agricultural regions, which cover more than 2 million square kilometers of Monsoon Asia, have been transformed profoundly over the past fifty years by fine-scale changes in land cover caused by unprecedented changes in population, technology and social conditions. Using a regional sampling and upscaling design coupled with high-resolution landscape change measurements at five field sites, we investigated long-term changes in land cover and ecological processes, circa 1945 to 2002, within and across China's densely populated agricultural regions. As expected, the construction of buildings and roads increased impervious surface area over time, but the total net increase was surprising, being similar in magnitude to the total current extent of China's cities. Agricultural land area declined over the same period, while tree cover increased, by about 10%, driven by tree planting and regrowth around new buildings, the introduction of perennial agriculture, improved forestry, and declines in annual crop cultivation. Though changes in impervious surface areas were closely related to changes in population density, long-term changes in agricultural land and tree cover were unrelated to populated density and required explanation by more complex models with strong regional and biophysical components. Moreover, most of these changes occurred primarily at fine spatial scales (< 30 m), under the threshold for conventional global and regional land cover change measurements. Given that these changes in built structures and vegetation cover have the potential to contribute substantially to regional and global changes in biogeochemistry, hydrology, and land-atmosphere interactions, future investigations of these changes and their impacts across Monsoon Asia would benefit from models

    Tradable emissions allowance systems to reduce carbon emissions are increasingly promoted as means to mitigate climate change. This paper briefly reviews the application of such systems at the global, regional, and corporate scales. Given the recent expansion of cap-and-trade systems at the regional level, the paper concentrates on energy and economic implications at that level, using the decision of the State of Maryland, USA, to join the Regional Greenhouse Gas Initiative as an illustration. The paper presents the results of an analysis of the implications for technology choice, generation capacity, energy reliability, and cost to ratepayers of that decision, combining a national electricity market model with a regional model that includes market power and an economic impact model. The results suggest several issues that will be key to the acceptability and effectiveness of cap-and-trade systems for regional climate change mitigation policy, including rules for distribution of allowances and subsidies for energy efficiency programs.

    We investigated the impact of a sustainable development technology on the macroeconomic variables in a small economy utilizing a case study with a stochastically improving energy saving technology and a stochastically increasing energy price. The results show the technological displacement effects of energy saving technology are stronger, but there are more ambiguous instantaneous returns to physical capital. However, the energy saving technology's displacement effects might not affect the conditions under which the Harberger-Laursen-Metzler (HLM) effect holds. The effects of rising energy prices on bonds are stronger, and there are more ambiguous instantaneous returns, but the conditions under which the HLM effect holds are different.

    1995-03-01

    The purpose of this study is to estimate the potential employment and income benefits of the emerging market for gas cooling products. The emphasis here is on exports because that is the major opportunity for the U.S. heating, ventilating, and air-conditioning (HVAC) industry. But domestic markets are also important and considered here because without a significant domestic market, it is unlikely that the plant investments, jobs, and income associated with gas cooling exports would be retained within the United States. The prospects for significant gas cooling exports appear promising for a variety of reasons. There is an expanding need for cooling in the developing world, natural gas is widely available, electric infrastructures are over-stressed in many areas, and the cost of building new gas infrastructure is modest compared to the cost of new electric infrastructure. Global gas cooling competition is currently limited, with Japanese and U.S. companies, and their foreign business partners, the only product sources. U.S. manufacturers of HVAC products are well positioned to compete globally, and are already one of the faster growing goods-exporting sectors of the U.S. economy. Net HVAC exports grew by over 800 percent from 1987 to 1992 and currently exceed $2.6 billion annually (ARI 1994). Net gas cooling job and income creation are estimated using an economic input-output model to compare a reference case to a gas cooling scenario. The reference case reflects current policies, practices, and trends with respect to conventional electric cooling technologies. The gas cooling scenario examines the impact of accelerated use of natural gas cooling technologies here and abroad.

    Battelle has conducted a three-year effort, funded by the U. S Department of Energy's (DOE) Office of Technology Development, to involve stakeholders in evaluating innovative technologies to clean up volatile organic compound (VOC) contamination at arid sites. Stakeholders have been encouraged to participate in the demonstration of these innovative technologies in order to improve decisions made by DOE and its contractors about technology development, demonstration, and deployment. The basic approach is to identify people and organizations with a stake in the remediation process, and hence in the demonstration of innovative technologies. Stakeholders have included public interest group and environmental group representatives, regulators, technology users, Native Americans, Hispanic community members, and local elected officials. These people are invited to be involved and they are presented with substantive information about the technologies. Their input in terms of identifying issues and concerns, defining the kinds of information needed from the demonstrations, and assessing the acceptability of the technologies for deployment, will help ensure that only broadly promising technologies are carried forward. This approach is designed to increase the likelihood of successful deployment of the new technologies needed to accomplish environmental restoration throughout the DOE complex and at private facilities. The hypothesis in conducting this regional stakeholder involvement program is that there will be different data requirements for different sites due to geographical, institutional, programmatic, and cultural differences at the sites. Identifying the broadest set of data requirements, collecting this information during the technology demonstration, and providing the results of the demonstration to stakeholders will enhance the acceptance of the technology at these sites and, thereby, enhance the technology's deployability

    Background Dengue is an increasing public health concern in Brazil. There is a need for an updated evaluation of the economic impact of dengue within the country. We undertook this multicenter study to evaluate the economic burden of dengue in Brazil. Methods We estimated the economic burden of dengue in Brazil for the years 2009 to 2013 and for the epidemic season of August 2012- September 2013. We conducted a multicenter cohort study across four endemic regions: Midwest, Goiania; Southeast, Belo Horizonte and Rio de Janeiro; Northeast: Teresina and Recife; and the North, Belem. Ambulatory or hospitalized cases with suspected or laboratory-confirmed dengue treated in both the private and public sectors were recruited. Interviews were scheduled for the convalescent period to ascertain characteristics of the dengue episode, date of first symptoms/signs and recovery, use of medical services, work/school absence, household spending (out-of-pocket expense) and income lost using a questionnaire developed for a previous cost study. We also extracted data from the patients’ medical records for hospitalized cases. Overall costs per case and cumulative costs were calculated from the public payer and societal perspectives. National cost estimations took into account cases reported in the official notification system (SINAN) with adjustment for underreporting of cases. We applied a probabilistic sensitivity analysis using Monte Carlo simulations with 90% certainty levels (CL). Results We screened 2,223 cases, of which 2,035 (91.5%) symptomatic dengue cases were included in our study. The estimated cost for dengue for the epidemic season (2012–2013) in the societal perspective was US$ 468 million (90% CL: 349–590) or US$ 1,212 million (90% CL: 904–1,526) after adjusting for under-reporting. Considering the time series of dengue (2009–2013) the estimated cost of dengue varied from US$ 371 million (2009) to US$ 1,228 million (2013). Conclusions The economic burden

    Full Text Available The aim of this paper is to evaluate the stage of Information Technology implementation in the agricultural farms in Romania. At the level of each Romanian development region it was performed a research for identifying the use of Information Technology. In addition, it was conducted a study on the management applied in the agricultural farms, the market of information solutions developed for farms specific needs and of the politics that promote the investments in the Information Technology. The research had as result the identification of the main factors that lead to a reduced Information Technology penetration rate in the Romanian agriculture such as: the reduced number of agricultural farms with legal personality, the decreased investment potential of agricultural farms, the lack of interest of software developer enterprises in providing Farm Management Information Systems and the poor professional skills of farm managers and their employees in the Information Technology field.

  6. Energy and global warming impacts of CFC alternative technologies

    International Nuclear Information System (INIS)

    Fischer, S.K.; Fairchild, P.D.; Hughes, P.J.

    1992-01-01

    Chlorofluorocarbons (CFCs) are used in a number of applications, and volumes of CFCs used grew at a tremendous pace during the 1960s and 1970s. However, in the mid-1980s, it was confirmed that these extremely useful chemicals contribute to the destruction of stratospheric ozone. These chemicals are being phased out of use rapidly to protect the ozone layer and it is very important that the replacements for CFSs do not result in a net increase in global warming by introducing less efficient processes that lead to higher energy use and increased carbon dioxide emissions. A study was conducted to identify those alternative chemicals and technologies that could replace CFCs in energy related applications before the year 2000, and to assess the total potential impact of these alternatives on global warming. The analysis for this project included an estimate of the direct effects from the release of blowing agents, refrigerants, and solvents into the atmosphere and the indirect effects in the form of carbon dioxide emissions resulting from energy use for commercial and residential heating and cooling, household and commercial refrigeration, building and automobile air-conditioning, and general metal and electronics solvent cleaning. The discussion in this paper focuses on those aspects of the study relevant to refrigeration and air-conditioning. In general the use of hydrofluorocarbon (HFC) and hydrochlorofluorocarbon (HCFC) alternatives for CFCs lead to large and sometimes dramatic reduction in total equivalent warming impact (TEWI), lifetime equivalent CO 2 emission. Most of the reductions result from decreased direct effects without significant changes in energy use. 3 refs., 3 figs., 1 tab

    Wire-grid polarizer sheets in the terahertz region have been fabricated on flexible substrates by nanoimprint technology. They show an ideal polarization property in the terahertz frequency region, whereas the cost is very low. Since the wire pitch is far smaller than the wavelength, the effective medium theory agrees well with experimental results. The effective medium theory shows the possibility of further improvement of polarization properties by selecting appropriate materials for wire grids. © 2011 Optical Society of America

    2005-03-01

    Lasers have become accepted "tools" by a number of industries. Everything from cars to heart pacemakers to greeting cards are now using lasers to cut, drill, clad, heat treat, and weld/join. The market for industrial laser systems is expanding. For the first quarter of 2004 the sales in lasers systems increased 40% to over $120 million1. Some of this increase in sales may be due to the fact that lasers are now considered reliable and have proven to be economical. The primary industrial laser systems today are the CO2 and Nd:YAG (lamp pumped) lasers especially at the higher powers. Both laser designs have evolved in power, beam quality, and reliability. At the same time laser manufacturers have developed methods to decrease the fabrication cost for the lasers. While these improvements have had a major impact on the operating cost of lasers, significant additional improvements do not seem possible in the near future for these lasers. As a result other advances in laser technologies (diode, diode pumped Nd:YAG, disc, and Yb fiber) are being examined.

  19. Devolving healthcare delivery to regional health authorities: is health technology assessment prepared to follow?

    Science.gov (United States)

    Gibis, Bernhard R; Juzwishin, Don

    2003-01-01

    Since the establishment of health technology assessment units in the latter 1980s, Canada has witnessed an unprecedented transformation of the governance, management and service delivery of its healthcare system. In Alberta, this transformation culminated in the establishment of regional health authorities that provide integrated healthcare to Albertans. With the shift of responsibility for healthcare delivery from the provincial to the regional level, the Alberta Heritage Foundation for Medical Research HTA unit recognized that for health technology assessment to continue to be relevant, it must follow this change. Four steps were taken to refocus the unit's scope: a thorough analysis of the healthcare environment; face-to-face interviews with the chief executive officers of the regions; the development of a framework for HTA in the regions; and the organization of a conference on evidence-based decision making. These steps were helpful in bringing HTA to the attention of regional decision makers. A formal, analytical assessment of the regional healthcare environment, provision of general information (through the framework and conference) and individual information (through face-to-face interviews) enabled a proactive engagement with regions. However, to meet the demands and needs of a population that expects comprehensive coverage that delivers "state of the art" diagnostics and treatments, the efficacy and effectiveness of interventions can sometimes be of subordinate importance.

    2015-03-01

    To begin understanding the potential economic impacts of large-scale WEC technology, the Bureau of Ocean Energy Management (BOEM) commissioned the National Renewable Energy Laboratory (NREL) to conduct an economic impact analysis of largescale WEC deployment for Oregon coastal counties. This report follows a previously published report by BOEM and NREL on the jobs and economic impacts of WEC technology for the entire state (Jimenez and Tegen 2015). As in Jimenez and Tegen (2015), this analysis examined two deployment scenarios in the 2026-2045 timeframe: the first scenario assumed 13,000 megawatts (MW) of WEC technology deployed during the analysis period, and the second assumed 18,000 MW of WEC technology deployed by 2045. Both scenarios require major technology and cost improvements in the WEC devices. The study is on very large-scale deployment so readers can examine and discuss the potential of a successful and very large WEC industry. The 13,000-MW is used as the basis for the county analysis as it is the smaller of the two scenarios. Sensitivity studies examined the effects of a robust in-state WEC supply chain. The region of analysis is comprised of the seven coastal counties in Oregon—Clatsop, Coos, Curry, Douglas, Lane, Lincoln, and Tillamook—so estimates of jobs and other economic impacts are specific to this coastal county area.

    1998-11-01

    In this thesis a method to calculate the greenhouse impact of continuous, time-dependent, non-global greenhouse gas emissions is used to estimate the impact of estimated anthropogenic pre-1990 and future (post 1990) emissions of CO{sub 2}, CH{sub 4} and N{sub 2}O from Finland and the Nordic countries. Estimates for the impact of Finnish CFCs and their substitutes and the significance of Finnish forests as carbon sink are also calculated. The method is also used to compare several different wood and peat energy production schemes with fossil fuel use, in terms of caused greenhouse impact. The uncertainty of the results is examined. The greenhouse impact is measured in this thesis as the global mean direct radiative forcing caused by the emissions. Radiative forcing is the driving force behind the climate change and as such it can be used to assess the ensuing climate change. The method is suitable for greenhouse agents that can be considered to be well mixed in the atmosphere (mainly CO{sub 2}, CH{sub 4}, N{sub 2}O and both CFCs and their substitutes). According to the results Finnish greenhouse impact due to anthropogenic CO{sub 2}, CH{sub 4} and N{sub 2}O emissions has increased eight-fold during this century, and will very likely remain higher than current level throughout the next century. The impact of the Nordic countries has followed the same general pattern as Finland. It is likely that the per capita radiative forcing of the Nordic countries will remain above the global average. The uncertainty of the absolute results is quite high due to uncertain knowledge at several stages of the calculation. When the results are used in comparisons (e.g. between emission scenarios, or emissions of different countries), the accuracy of the results increases considerably. (orig.) 54 refs.

    2016-05-01

    Full Text Available Nowadays, EU28 operates in a very sensitive socio-economic environment. This is why the paper faces to the idea of changing the political approach in the EU. In order to support this idea, two essential common policies (Regional Policy and Cohesion Policy are analyzed, using pertinent indicators, as GDP per capita, gross value added and labor productivity. A comparative analysis covers EU28 and Euro area. On the other hand, the regional analysis points out the economic disparities between NUTS2 regions. The intermediate conclusions of the analysis led to a cluster approach for the Member States. Moreover, the forecasting procedures applied to the above three economic indicators led to the same idea: an EU more divided than integrated. The main conclusion of the paper is that the present economic approach has to be change into another focused on maintaining and, after that, decreasing the present European socio-economic disparities.

    2016-01-01

    This paper provides a critical review of different approaches applied in the Belgian asphalt sector in order to reduce the environmental impact of bituminous road construction works. The focus is on (1) reusing reclaimed asphalt pavement, (2) reducing the asphalt production temperature, and (3) prolonging the service life of the pavement. Environmental impact assessment of these methods is necessary to be able to compare these approaches and understand better the ability to reduce the environmental impact during the life cycle of the road pavement. Attention should be drawn to the possible shift in environmental impact between various life cycle stages, e.g., raw material production, asphalt production, or waste treatment. Life cycle assessment is necessary to adequately assess the environmental impact of these approaches over the entire service life of the bituminous pavement. The three approaches and their implementation in the road sector in Flanders (region in Belgium) are described and the main findings from life cycle assessment studies on these subjects are discussed. It was found from the review that using reclaimed asphalt pavement in new bituminous mixtures might yield significant environmental gains. The environmental impact of the application of warm mix asphalt technologies, on the other hand, depends on the technique used. - Highlights: • Recycling, lower production temperature and durability of asphalt are investigated. • The use of RAP in new asphalt mixtures yields significant environmental advantages. • It would be beneficial to allow RAP in asphalt mixtures for wearing courses. • The use of particular additives might counteract the environmental gain from WMA. • The service life and the environmental data source influence the LCA results.

    Climate change and human activities are directly or indirectly influence the acceleration of environmental problems and natural hazards such as forest fires, drought and floods in the Asia-Pacific countries. Satellite technology has become one of the key information sources in assessment, monitoring and mitigation of these hazards and related phenomenon. However, there are still gaps between science and application of space technology in practical usage. Asia-Pacific Regional Space Agency Forum (APRSAF) recommended to initiate the Space Applications for Environment (SAFE) proposal providing opportunity to potential user agencies in the Asia Pacific region to develop prototype applications of space technology for number of key issues including forest resources management, coastal monitoring and management, agriculture and food security, water resource management and development user-friendly tools for application of space technology. The main activity of SAFE is SAFE prototyping. SAFE prototyping is a demonstration for end users and decision makers to apply space technology applications for solving environmental issues in Asia-Pacific region. By utilizing space technology and getting technical support by experts, prototype executers can develop the application system, which could support decision making activities. SAFE holds a workshop once a year. In the workshop, new prototypes are approved and the progress of on-going prototypes are confirmed. Every prototype is limited for two years period and all activities are operated by volunteer manner. As of 2016, 20 prototypes are completed and 6 prototypes are on-going. Some of the completed prototypes, for example drought monitoring in Indonesia were applied to operational use by a local official organization.

  6. Impacts Seed Technology Improvement on Economic Aspects of Chilli Production in Central Java - Indonesia

    2016-06-01

    Full Text Available Vegetable production, including that of chillies, plays an important role in agricultural sector and rural economic development worldwide. This is because of greater farm productivity with regard to vegetables than cereal and staple crops. This paper analyses the impact of seed technology development on the economic aspects of chilli production in Central Java. Particular attention is paid to improved varieties of chilli. Potential consequences of seed technology development are discussed. Data of this study are compiled from surveys conducted in three selected chilli producing regions in 2010-2012. The results show that the major varieties of chilli grown by surveyed farmers are grouped into three broad types: hybrids, local and improved open pollinated varieties. The chilli varieties farmers selected varied according to location and cropping season. In the dry season, farmers grew similar proportions of hybrid, local, and open pollinated types. Nevertheless, there were differences among the survey sites. Farmers grew different varieties to exploit seasonal microclimates and market preferences. Mostly, farmers selected varieties for economic motives. The consequence of growing hybrids was less use of agrochemicals, particularly pesticides, than for other varieties. Overall, they show the best economic performance in the study site. Development of seed technology should consider agro-ecological and economic aspects to obtain better outcomes. Private sector and national research institutions need to collaborate more to utilise available genetic resources to produce better varieties of chilli.

    Full Text Available The scope of our research is the university as the key actor of economic change. Historically, it is possible to allocate four types of the university by analogy to four industrial revolutions. In the conditions of the fourth industrial revolution, there is a radical shift in the university model. From research and development and technology transfer, the university moves to the creation of the intellectual capital. The university does not simply conduct R&D for business but creates essentially new industries. The university becomes the center around which the new hi-tech enterprises grow. This phenomenon has been entitled entrepreneurial university that is the main actor of the entrepreneurial (startup economy. In this study, we examined the different approaches to the evaluation of universities, first of all, global university rankings. Each ranking methodology assesses the different functional areas; a unified methodology of the evaluation of university as a complex system is currently lacking. At the same time, we tried to define the mechanism of the impact of the universities on regional economic growth grounding on a case of Russian universities. A comparative study of Novosibirsk and Tomsk universities has revealed key problem areas and barriers in the process of university engagement in regional economic systems. The findings will be used in further theoretical and applied research, as well as decision-making in the area of educational policy

  10. The impact of domestic trade on China's regional energy uses: A multi-regional input–output modeling

    Zhang, Bo; Chen, Z.M.; Xia, X.H.; Xu, X.Y.; Chen, Y.B.

    2013-01-01

    To systematically reveal how domestic trade impacts on China's regional energy uses, an interprovincial input–output modeling is carried out to address demand-derived energy requirements for the regional economies in 2007 based on the recently available data. Both the energy uses embodied in final demand and interregional trade are investigated from the regional and sectoral insights. Significant net transfers of embodied energy flows are identified from the central and western areas to the eastern area via interregional trade. Shanxi is the largest energy producer and interregional embodied energy deficit receiver, in contrast to Guangdong as the largest energy user and surplus receiver. By considering the impacts of interregional trade, the energy uses of most eastern regions increase remarkably. For instance, Shanghai, Hainan, Zhejiang, Beijing, Jiangsu and Guangdong have their embodied energy requirements 87.49, 19.97, 13.64, 12.60, 6.46 and 6.38 times of their direct energy inputs, respectively. In contrast, the embodied energy uses of some central and western regions such as Inner Mongolia, Shanxi, Xinjiang, Shaanxi and Guizhou decrease largely. The results help understand the hidden network linkages of interregional embodied energy flows and provide critical insight to amend China's current end-reduction-oriented energy policies by addressing the problem of regional responsibility transfer. - Highlights: • Demand-derived energy requirements for China's regional economies are addressed. • Significant interregional transfers of embodied energy flows are identified. • Energy surpluses are obtained by 19 regions and deficits by the other 11 regions. • The eastern regions should take more responsibility for reducing China's energy uses

    Prudent assimilation of AIRS thermodynamic profiles and quality indicators can improve initial conditions for regional weather models. AIRS-enhanced analysis has warmer and moister PBL. Forecasts with AIRS profiles are generally closer to NAM analyses than CNTL. Assimilation of AIRS leads to an overall QPF improvement in 6-h accumulated precipitation forecasts. Including AIRS profiles in assimilation process enhances the moist instability and produces stronger updrafts and a better precipitation forecast than the CNTL run.

    2005-11-17

    The World Health Organisation estimates that the warming and precipitation trends due to anthropogenic climate change of the past 30 years already claim over 150,000 lives annually. Many prevalent human diseases are linked to climate fluctuations, from cardiovascular mortality and respiratory illnesses due to heatwaves, to altered transmission of infectious diseases and malnutrition from crop failures. Uncertainty remains in attributing the expansion or resurgence of diseases to climate change, owing to lack of long-term, high-quality data sets as well as the large influence of socio-economic factors and changes in immunity and drug resistance. Here we review the growing evidence that climate-health relationships pose increasing health risks under future projections of climate change and that the warming trend over recent decades has already contributed to increased morbidity and mortality in many regions of the world. Potentially vulnerable regions include the temperate latitudes, which are projected to warm disproportionately, the regions around the Pacific and Indian oceans that are currently subjected to large rainfall variability due to the El Niño/Southern Oscillation sub-Saharan Africa and sprawling cities where the urban heat island effect could intensify extreme climatic events.

  17. Energy Performance Impacts from Competing Low-slope Roofing Choices and Photovoltaic Technologies

    Science.gov (United States)

    Nagengast, Amy L.

    With such a vast quantity of space, commercial low-slope roofs offer significant potential for sustainable roofing technology deployment. Specifically, building energy performance can be improved by installing rooftop energy technologies such as photovoltaic (PV) panels, and/or including designs such as white or green roofs instead of traditional black. This research aims to inform and support roof decisions through quantified energy performance impacts across roof choices and photovoltaic technologies. The primary dataset for this research was measured over a 16 month period (May 24, 2011 to October 13, 2012) from a large field experiment in Pittsburgh, Pennsylvania on top of a commercial warehouse with white, black and green roof sections, each with portions covered by polycrystalline photovoltaic panels. Results from the Pittsburgh experiment were extended to three different cities (San Diego, CA; Huntsville, AL; and Phoenix, AZ) chosen to represent a wide range of irradiance and temperature values. First, this research evaluated the difference in electricity production from a green-moss roof and black roof underneath photovoltaic panels to determine if the green roof's cooler air increases the panel efficiency. Second, separate studies examine 1) average hourly heat flux by month for unobstructed and shaded roof membranes 2) heat flux peak time delay, and 3) air temperature across roof types. Results of this research show green roofs slightly increased (0.8-1.5%) PV panel efficiency in temperatures approximately at or above 25° C (77°F) compared to black roofs. However in cool climates, like Pittsburgh, the roof type under the PV panels had little overall impact on PV performance when considering year round temperatures. Instead, roof decisions should place a stronger emphasis on heat flux impacts. The green roof outperformed both black and white roofs at minimizing total conductive heat flux. These heat flow values were used to develop a new, straight

    2011-01-01

    Standalone levelised cost assessments of electricity supply options miss an important contribution that renewable and non-fossil fuel technologies can make to the electricity portfolio: that of reducing the variability of electricity costs, and their potentially damaging impact upon economic activity. Portfolio theory applications to the electricity generation mix have shown that renewable technologies, their costs being largely uncorrelated with non-renewable technologies, can offer such benefits. We look at the existing Scottish generation mix and examine drivers of changes out to 2020. We assess recent scenarios for the Scottish generation mix in 2020 against mean-variance efficient portfolios of electricity-generating technologies. Each of the scenarios studied implies a portfolio cost of electricity that is between 22% and 38% higher than the portfolio cost of electricity in 2007. These scenarios prove to be mean-variance 'inefficient' in the sense that, for example, lower variance portfolios can be obtained without increasing portfolio costs, typically by expanding the share of renewables. As part of extensive sensitivity analysis, we find that Wave and Tidal technologies can contribute to lower risk electricity portfolios, while not increasing portfolio cost. - Research Highlights: → Portfolio analysis of scenarios for Scotland's electricity generating mix in 2020. → Reveals potential inefficiencies of selecting mixes based on levelised cost alone. → Portfolio risk-reducing contribution of Wave and Tidal technologies assessed.

  12. Assessing security technology's impact: old tools for new problems.

    Science.gov (United States)

    Kreissl, Reinhard

    2014-09-01

    The general idea developed in this paper from a sociological perspective is that some of the foundational categories on which the debate about privacy, security and technology rests are blurring. This process is a consequence of a blurring of physical and digital worlds. In order to define limits for legitimate use of intrusive digital technologies, one has to refer to binary distinctions such as private versus public, human versus technical, security versus insecurity to draw differences determining limits for the use of surveillance technologies. These distinctions developed in the physical world and are rooted in a cultural understanding of pre-digital culture. Attempts to capture the problems emerging with the implementation of security technologies using legal reasoning encounter a number of problems since law is by definition oriented backwards, adapting new developments to existing traditions, whereas the intrusion of new technologies in the physical world produces changes and creates fundamentally new problems.

    Riva, Giuseppe

    2012-01-01

    The goal of this paper is to introduce and describe the "Positive Technology" approach - the scientific and applied approach to the use of technology for improving the quality of our personal experience through its structuring, augmentation and/or replacement - as a way of framing a suitable object of study in the field of cyberpsychology and human-computer interaction. Specifically, we suggest that it is possible to use technology to influence three specific features of our experience - affective quality, engagement/actualization and connectedness - that serve to promote adaptive behaviors and positive functioning. In this framework, positive technologies are classified according to their effects on a specific feature of personal experience. More, for each level we have identified critical variables that can be manipulated to guide the design and development of positive technologies.

  20. The electrification of Nova Scotia, 1884--1973: Technological modernization as a response to regional disparity

    Science.gov (United States)

    King, Lionel Bradley

    This dissertation investigates local attempts to use technology as a force for regional rehabilitation in the economically-depressed Maritime region of Canada. At the time of Confederation in 1867, the Maritime province of Nova Scotia was prosperous, progressive, and cultured. By the end of the 1910s, the province had entered a long period of economic and social decline. Recent historiography has shown that, far from passively accepting their fate, Nova Scotians and other Maritimers, actively resisted marginalization with political, cultural, or social action. The thesis expands upon that literature by exploring technology-based strategies of provincial rehabilitation using Thomas P. Hughes's systems perspective and David E. Nye's semiotic approach. In doing so, it applies methods from the social constructivist school of the history of technology to the larger concerns of Maritime Canadian historiography. In large part, the North American culture of technology determined the ways in which Nova Scotians applied technological solutions to provincial concerns. Technology has long been central to the Western idea of progress. As the "high technology" of the late nineteenth and early twentieth centuries, electricity reinforced that view: its ephemeral nature and silent efficiency led people to endow it with transformative, even mystical, powers. As a result, Nova Scotians, adopted a program of electrical modernization in the late 1910s as a remedy for regional disparity. The Nova Scotia government's first step was the creation of an Ontario-style hydroelectric commission designed to bring order to the province's fragmented and inefficient electrical network. Over the next few decades, the Nova Scotia Power Commission implemented rural electrification, home modernization, and regional system-building models that had already proven successful in Ontario and the United States. The system-building philosophies behind these programs were adapted to local conditions and

  1. Impact of Technology and Feedstock Choice on the Environmental Footprint of Biofuels

    Science.gov (United States)

    Schultz, P. B.; Dodder, R. S.

    2012-12-01

    The implementation of the U.S. Renewable Fuel Standard program (RFS2) has led to a dramatic shift in the use of biofuel in the U.S. transportation system over the last decade. To satisfy this demand, the production of U.S. corn-based ethanol has grown rapidly, with an average increase of over 25% annually from 2002 to 2010. RFS2 requires a similarly steep increase in the production of advanced biofuels, such as cellulosic ethanol. Unlike corn-based ethanol, which is derived from the biochemical fermentation of sugars in wet and dry mills, it is likely that a more diverse suite of technologies will need to be developed to be able to meet the advanced biofuel RFS2 targets, including biochemical as well as thermochemical (e.g., gasification and pyrolysis) approaches. Rather than relying on energy crops, a potential advantage of thermochemical approaches is the ability to use a wider variety of feedstocks, including municipal solid waste and wood waste. In this work, we conduct a system-level analysis to understand how technology and feedstock choice can impact the environmental footprint of biofuels in the U.S. We use a least-cost optimization model of the U.S. energy system to account for interactions between various components of the energy system: industrial, transportation, electric, and residential/commercial sectors. The model was used to understand the scale of feedstock demand required from dedicated energy crops, as well as other biomass feedstocks, in order to meet the RFS2 mandate. On a regional basis, we compare the overall water-consumption and land requirements for biofuels production given a suite of liquid-fuel production technologies. By considering a range of scenarios, we examine how the use of various feedstocks (e.g., agricultural residues, wood wastes, mill residues and municipal wastes) can be used to off-set environmental impacts as compared to relying solely on energy crops.

  6. Working memory training using mental calculation impacts regional gray matter of the frontal and parietal regions.

    Directory of Open Access Journals (Sweden)

    Hikaru Takeuchi

    Full Text Available Training working memory (WM improves performance on untrained cognitive tasks and alters functional activity. However, WM training's effects on gray matter morphology and a wide range of cognitive tasks are still unknown. We investigated this issue using voxel-based morphometry (VBM, various psychological measures, such as non-trained WM tasks and a creativity task, and intensive adaptive training of WM using mental calculations (IATWMMC, all of which are typical WM tasks. IATWMMC was associated with reduced regional gray matter volume in the bilateral fronto-parietal regions and the left superior temporal gyrus. It improved verbal letter span and complex arithmetic ability, but deteriorated creativity. These results confirm the training-induced plasticity in psychological mechanisms and the plasticity of gray matter structures in regions that have been assumed to be under strong genetic control.

    Full Text Available The aim of the paper is to conduct a research on an impact of blockchain technology platform on the financial sector through cryptocurrency, and an impact on other industries.. The subject of research is not only this technology but also its commercial exploitation. In order to understand the platform, the starting point of this research is an analysis of how the technology functions, after that the advantages for business and economic transaction are identified, and finally the paper deals with an impact of new technology on business, above all on financial operations. The basic hypothesis is that blockchain has achieved a great impact on financial sector, also it has the potential to radically change only the financial sector but also the way we buy and sell, our interaction with the authorities as a way of verifying the ownership from the authorship and the organic food production. Using the available data and synthesis of knowledge from the fields of technology, economics, finance, and politics, 4 scenarios were set up for the future of underlying technology. The scenario approach combined with trend analysis in order to prove the starting hypothesis with high reliability. The research results show that the technology being investigated already has a profound impact on the financial sector, that it is in the initial phase of changing many industries, with the likelihood that they will change them significantly in the next five to ten years. Businesses increasingly discover the power of this technology to exploit the benefits of the Fourth Technological Revolution.

    Zhang, Y; Liu, X J

    2016-04-09

    Digital medical technologies or computer aided medical procedures, refer to imaging, 3D reconstruction, virtual design, 3D printing, navigation guided surgery and robotic assisted surgery techniques. These techniques are integrated into conventional surgical procedures to create new clinical protocols that are known as "digital surgical techniques". Conventional health care is characterized by subjective experiences, while digital medical technologies bring quantifiable information, transferable data, repeatable methods and predictable outcomes into clinical practices. Being integrated into clinical practice, digital techniques facilitate surgical care by improving outcomes and reducing risks. Digital techniques are becoming increasingly popular in trauma surgery, orthopedics, neurosurgery, plastic and reconstructive surgery, imaging and anatomic sciences. Robotic assisted surgery is also evolving and being applied in general surgery, cardiovascular surgery and orthopedic surgery. Rapid development of digital medical technologies is changing healthcare and clinical practices. It is therefore important for all clinicians to purposefully adapt to these technologies and improve their clinical outcomes.

    Full Text Available The sources of formation, environmental distribution and fate of persistent organic pollutants (POPs are increasingly seen as topics to be addressed and solved at the global scale. Therefore, there are already two international agreements concerning persistent organic pollutants: the Protocol of 1998 to the 1979 Convention on the Long-Range Transboundary Air Pollution on Persistent Organic Pollutants (Aarhus Protocol; and the Stockholm Convention on Persistent Organic Pollutants. For the assessment of environmental pollution of POPs, for the risk assessment, for the evaluation of new pollutants as potential candidates to be included in the POPs list of the Stokholmo or/and Aarhus Protocol, a set of different models are developed or under development. Multimedia models help describe and understand environmental processes leading to global contamination through POPs and actual risk to the environment and human health. However, there is a lack of the tools based on a systematic and integrated approach to POPs management difficulties in the region.

    Full Text Available Compensation payments are considered active labour market policies designed to increase efficiency, to mitigate unemployment and to sustaining employment. We tested this hypothesis for the period 1993-2013, in territorial structures (42 counties through a dynamic panel model (confirmed by Granger causality tests – Toda-Yamamoto version, and by means of error correction model. We found that the dynamics of regional employment are positively related to expenditure incurred for active policies and there are negatively correlated with the ratio between the unemployment average indemnity (and support allowance and the average net nominal monthly salary earnings. But, the connexion between employment and compensation payments converges extremely slowly for a long-term stable relationship.

  3. Environmental impacts of shipping in 2030 with a particular focus on the Arctic region

    Directory of Open Access Journals (Sweden)

    S. B. Dalsøren

    2013-02-01

    Full Text Available We quantify the concentrations changes and Radiative Forcing (RF of short-lived atmospheric pollutants due to shipping emissions of NOx, SOx, CO, NMVOCs, BC and OC. We use high resolution ship emission inventories for the Arctic that are more suitable for regional scale evaluation than those used in former studies. A chemical transport model and a RF model are used to evaluate the time period 2004–2030, when we expect increasing traffic in the Arctic region. Two datasets for ship emissions are used that characterize the potential impact from shipping and the degree to which shipping controls may mitigate impacts: a high (HIGH scenario and a low scenario with Maximum Feasible Reduction (MFR of black carbon in the Arctic. In MFR, BC emissions in the Arctic are reduced with 70% representing a combination technology performance and/or reasonable advances in single-technology performance. Both scenarios result in moderate to substantial increases in concentrations of pollutants both globally and in the Arctic. Exceptions are black carbon in the MFR scenario, and sulfur species and organic carbon in both scenarios due to the future phase-in of current regulation that reduces fuel sulfur content. In the season with potential transit traffic through the Arctic in 2030 we find increased concentrations of all pollutants in large parts of the Arctic. Net global RFs from 2004–2030 of 53 mW m−2 (HIGH and 73 mW m−2 (MFR are similar to those found for preindustrial to present net global aircraft RF. The found warming contrasts with the cooling from historical ship emissions. The reason for this difference and the higher global forcing for the MFR scenario is mainly the reduced future fuel sulfur content resulting in less cooling from sulfate aerosols. The Arctic RF is largest in the HIGH scenario. In the HIGH scenario ozone dominates the RF during the transit season (August–October. RF due to BC in air, and

    Power systems of the future are likely to require additional flexibility. This has been well studied from an operational perspective, but has been more difficult to incorporate into capacity expansion models (CEMs) that study investment decisions on the decadal scale. There are two primary reasons for this. First, the necessary input data, including cost and resource projections, for flexibility options like demand response and storage are significantly uncertain. Second, it is computationally difficult to represent both investment and operational decisions in detail, the latter being necessary to properly value system flexibility, in CEMs for realistically sized systems. In this work, we extend a particular CEM, NREL's Resource Planning Model (RPM), to address the latter issue by better representing variable generation impacts on operations, and then adding two flexible technologies to RPM's suite of investment decisions: interruptible load and utility-scale storage. This work does not develop full suites of input data for these technologies, but is rather methodological and exploratory in nature. We thus exercise these new investment decisions in the context of exploring price points and value streams needed for significant deployment in the Western Interconnection by 2030. Our study of interruptible load finds significant variation by location, year, and overall system conditions. Some locations find no system need for interruptible load even with low costs, while others build the most expensive resources offered. System needs can include planning reserve capacity needs to ensure resource adequacy, but there are also particular cases in which spinning reserve requirements drive deployment. Utility-scale storage is found to require deep cost reductions to achieve wide deployment and is found to be more valuable in some locations with greater renewable deployment. Differences between more solar- and wind-reliant regions are also found: Storage

    2017-04-01

    Accurate and reliable real-time monitoring and dissemination of observations of surface weather conditions is critical for a variety of societal applications. Applications that provide local and regional information about temperature, precipitation, moisture, and winds, for example, are important for agriculture, water resource monitoring, health, and monitoring of hazard weather conditions. In many regions of the World, surface weather stations are sparsely located and/or of poor quality. Existing stations have often been sited incorrectly, not well-maintained, and have limited communications established at the site for real-time monitoring. The University Corporation for Atmospheric Research (UCAR)/National Center for Atmospheric Research (NCAR), with support from USAID, has started an initiative to develop and deploy low-cost weather instrumentation in sparsely observed regions of the world. The project is focused on improving weather observations for environmental monitoring and early warning alert systems on a regional to global scale. Instrumentation that has been developed use innovative new technologies such as 3D printers, Raspberry Pi computing systems, and wireless communications. The goal of the project is to make the weather station designs, software, and processing tools an open community resource. The weather stations can be built locally by agencies, through educational institutions, and residential communities as a citizen effort to augment existing networks to improve detection of natural hazards for disaster risk reduction. The presentation will provide an overview of the open source weather station technology and evaluation of sensor observations for the initial networks that have been deployed in Africa.

    The aim of this study was to develop an health technology assessment (HTA) decision tool to support the decision-making process on health technologies for hospital decision makers in cross-border regions. Several methods were used to collect information necessary to develop the cross-border mini-HTA decision tool. The literature was inventoried on HTA in border regions and local settings and the use of HTA by local decision makers. Semi-structured interviews with hospital decision makers in cross-border regions were also performed. Based on group discussion of the resulting information, it was decided to use the Danish mini-HTA guideline as a starting point for development of the decision tool. After finishing the first version of the decision tool it was tested in two pilot studies. Some questions in the Danish mini-HTA guideline were not relevant. Other questions needed rephrasing and questions about cross-border situations were added. The pilots showed several missing topics, including legal questions and reimbursement issues. The final decision tool consists of three sections: a general section, a section for hospitals not cooperating cross-border and a section for hospitals that are cooperating with hospitals across a national or regional border. Based on our literature search, this may be the first cross-border mini-HTA decision tool. The decision tool will be of help for healthcare professionals and decision makers in border settings who would like to use HTA evidence to support their decision-making process.

    A major theme of the Third European Congress on Technology assessment, ``Technology and Democracy`` was related to the question of how technology assessment may assist in the creation of a better foundation for decision-making when new technologies are introduced. The discussion, which involved politicians, researchers and representatives from industry, trade unions and various interest groups, focussed on how technology assessment can facilitate the creation of a dialogue between the parties involved in the decision-making processes. The Congress concluded in general, that as a result of the increasing complexity of our societies, the need for technology assessment to create the necessary multidimensional foundation for decision-making becomes more and more urgent. Such decisions will choose technologies with built-in opportunities and reduced risk factors. It was stated that ordinary people, if adequately informed, are able to form opinions on this. The involvement of citizens and the opening of a democratic debate put limits on the use of technology and heightens its acceptability, which results in an improvement of its quality and productivity. Technology assessment cases from all over Europe were presented. The workshop conclusions are included in Volume I. Volume II includes the papers form the Post-Congress workshop, ``Methods in Technology Assessment and Decision-making`` and the conclusions from the Post-Congress Workshop. (AB)

    Land use/land cover (LULC) change directly impacts the partitioning of surface mass and energy fluxes. Regional-scale weather and climate are potentially altered by LULC if the resultant changes in partitioning of surface energy fluxes are significant enough to induce changes in the evolution of the planetary boundary layer and its interaction with the atmosphere above. Dynamics of land use, particularly those related to the social dimensions of the Earth System, are often simplified or not represented in regional land-atmosphere models or Earth System Models. This study explores the role of LULC change on a regional hydroclimate system, focusing on potential hydroclimate changes arising from timber harvesting due to a land grab boom in Mozambique. We also focus more narrowly at quantifying regional impacts on Gorongosa National Park, a nationally important economic and biodiversity resource in southeastern Africa. After nationalizing all land in 1975 after Mozambique gained independence, complex social processes, including an extended low intensity conflict civil war and economic hardships, led to an escalation of land use rights grants to foreign governments. Between 2004 and 2009, large tracts of land were requested for timber. Here we use existing tree cover loss datasets to more accurately represent land cover within a regional weather model. LULC in a region encompassing Gorongosa is updated at three instances between 2001 and 2014 using a tree cover loss dataset. We use these derived LULC datasets to inform lower boundary conditions in the Weather Research and Forecasting (WRF) model. To quantify potential hydrometeorological changes arising from land use change, we performed a factorial-like experiment by mixing input LULC maps and atmospheric forcing data from before, during, and after the land grab. Results suggest that the land grab has impacted microclimate parameters in a significant way via direct and indirect impacts on land-atmosphere interactions

    Every year, hundreds of thousands of hectares of European forests are destroyed by fires. Due to the particular topography, landscape and demographic distribution in Europe (very different from typical scenarios of China, USA, Canada and Australia), rapidity in fire sighting is still the determining factor in limiting damages to people and goods. Moreover, the possibility of early fire detection means also potentially to reduce the size of the event to be faced, the necessary fire fighting resources and, therefore, even the reaction times. In such a context, integration of satellite technologies (mainly high temporal resolution data) and traditional surveillance systems within the fire fighting procedures seems to positively impact on the effectiveness of active fire fighting as demonstrated by recent experiences over Italian territory jointly performed by University of Basilicata, IMAA-CNR and Local Authorities. Real time implementation was performed since 2007, during fire seasons, over several Italian regions with different fire regimes and features, in order to assess the actual potential of different satellite-based fire detection products to support regional and local authorities in efficiently fighting fires and better mitigating their negative effects. Real-time campaigns were carried out in strict collaboration with end-users within the framework of specific projects (i.e. the AVVISA, AVVISTA and AVVISA-Basilicata projects) funded by Civil Protection offices of Regione Lombardia, Provincia Regionale di Palermo and Regione Basilicata in charge of fire risk management and mitigation. A tailored training program was dedicated to the personnel of Regional Civil Protection offices in order to ensure the full understanding and the better integration of satellite based products and tools within the existing fire fighting protocols. In this work, outcomes of these practices are shown and discussed, especially highlighting the impact that a real time satellite

    Full Text Available Abstract Background In Canada, workforce shortages in the health care sector constrain the ability of the health care system to meet the needs of its population and of its health care professionals. This issue is of particular importance in peripheral regions of Quebec, where significant inequalities in workforce distribution between regions has lead to acute nursing shortages and increased workloads. Information and communication technologies (ICTs are innovative solutions that can be used to develop strategies to optimise the use of available resources and to design new nursing work practices. However, current knowledge is still limited about the real impact of ICTs on nursing recruitment and retention. Our aim is to better understand how work practice reorganization, supported by ICTs, and particularly by telehealth, may influence professional, educational, and organizational factors relating to Quebec nurses, notably those working in peripheral regions. Methods/Design First, we will conduct a descriptive study on the issue of nursing recruitment. Stratified sampling will be used to select approximately twenty innovative projects relating to the reorganization of work practices based upon ICTs. Semi-structured interviews with key informants will determine professional, educational, and organizational recruitment factors. The results will be used to create a questionnaire which, using a convenience sampling method, will be mailed to 600 third year students and recent graduates of two Quebec university nursing faculties. Descriptive, correlation, and hierarchical regression analyses will be performed to identify factors influencing nursing graduates' intentions to practice in peripheral regions. Secondly, we will conduct five case studies pertaining to the issue of nursing retention. Five ICT projects in semi-urban, rural, and isolated regions have been identified. Qualitative data will be collected through field observation and approximately

    This population-based descriptive epidemiology study demonstrates that rates of conjoined twins, teratomas, neural tube defects, microcephaly, and microphthalmia in the Rivne province of Ukraine are among the highest in Europe. The province is 200 km distant from the Chornobyl site and its northern half, a region known as Polissia, is significantly polluted by ionizing radiation. The rates of neural tube defects, microcephaly and microphthalmia in Polissia are statistically significantly higher than in the rest of the province. A survey of at-birth head size showed that values were statistically smaller in males and females born in one Polissia county than among neonates born in the capital city. These observations provide clues for confirmatory and cause-effect prospective investigations. The strength of this study stems from a reliance on international standards prevalent in Europe and a decade-long population-based surveillance of congenital malformations in two distinct large populations. The limitations of this study, as those of other descriptive epidemiology investigations, is that identified cause-effect associations require further assessment by specific prospective investigations designed to address specific teratogenic factors.

  15. Cuban Migration Trends and Their Impact on Central America Region

    Directory of Open Access Journals (Sweden)

    Charleene Cortez Sosa

    2017-06-01

    Full Text Available In recent years, the migration of Cuban population has taken new directions; this is mainly due to the migration policy flexibility adopted by the Cuban government and other Latin America governments, such as Ecuador, Grenada, Trinidad and Tobago, Dominican Republic, and Haiti, among others, by issuing visas in favorable conditions for the population. Although there are varied reasons to migrate, this population has traditionally migrated motivated by the United States Cuban Adjustment Act which grants administrative advantages for regularization; no other country of the continent offers this privilege. Due to their political exile condition, whoever arrives to the United States will easily have access to legal mechanisms for migrant regularization. Although there has been great work on migration in general terms, little has been addressed on the Cuban migration in the Central American region; possibly this is due to the difficulty to find quantitative information in this regard. The article aims to facilitate the understanding of migration in a context of flexibility and establishment of new relations between the Caribbean and Central America.

    Full Text Available The present paper will try to offer an overview of the interpenetration and integration of two major areas: planning and environment, because we live in a time where most of us live in urban areas (75% of Europe’s population and not in the rural areas. Starting with 2020, according to projections made in the field,the proportion will be 80%. Consequently, the demand for land within and around cities will only become more acute, which already can be seen at the national level. Urban sprawl in the last period of time has already recontour landscapes, which will affect the quality of human life and environment. And perhaps it is not incidentally that the urban planning and management have reached today, the priority issues on the global political agenda. Thus we will treat through this paper will follow the existence of cohesion between land andenvironment. Yet this requires consistent interpretation of laws and their application and its implications. Having this aspect in front, the literature in domain and the EU Treaties our paper could be an efficient example for local authorities when prepare the future planning plans, in order to better uses of available resources from any region.

    1993-01-01

    To assist NASA and the Air Force in determining how and when to invest in virtual environment (VE) technology for maintenance training, we identified possible roles for VE technology in such training, assessed its cost-effectiveness relative to existing technologies, and formulated recommendations for a research agenda that would address instructional and system development issues involved in fielding a VE training system. In the first phase of the study, we surveyed VE developers to forecast capabilities, maturity, and estimated costs for VE component technologies. We then identified maintenance tasks and their training costs through interviews with maintenance technicians, instructors, and training developers. Ten candidate tasks were selected from two classes of maintenance tasks (seven aircraft maintenance and three space maintenance) using five criteria developed to identify types of tasks most likely to benefit from VE training. Three tasks were used as specific cases for cost-benefit analysis. In formulating research recommendations, we considered three aspects of feasibility: technological considerations, cost-effectiveness, and anticipated R&D efforts. In this paper, we describe the major findings in each of these areas and suggest research efforts that we believe will help achieve the goal of a cost-effective VE maintenance training system by the next decade.

    There is an imminent need to downscale the global climate models used by international consortiums like the IPCC (Intergovernmental Panel on Climate Change) to predict the future regional impacts of climate change. To meet this need, a "place-based" climate model that makes specific regional projections about future environmental conditions local inhabitants could face is being created by the Mailman School of Public Health at Columbia University, in collaboration with other researchers and universities, for New York City and the 31 surrounding counties. This presentation describes the design and initial results of this modeling study, aimed at simulating the effects of global climate change and regional land use change on climate and air quality over the northeastern United States in order to project the associated public health impacts in the region. Heat waves and elevated concentrations of ozone and fine particles are significant current public health stressors in the New York metropolitan area. The New York Climate and Health Project is linking human dimension and natural sciences models to assess the potential for future public health impacts from heat stress and air quality, and yield improved tools for assessing climate change impacts. The model will be applied to the NY metropolitan east coast region. The following questions will be addressed: 1. What changes in the frequency and severity of extreme heat events are likely to occur over the next 80 years due to a range of possible scenarios of land use and land cover (LU/LC) and climate change in the region? 2. How might the frequency and severity of episodic concentrations of ozone (O3) and airborne particulate matter smaller than 2.5 æm in diameter (PM2.5) change over the next 80 years due to a range of possible scenarios of land use and climate change in the metropolitan region? 3. What is the range of possible human health impacts of these changes in the region? 4. How might projected future human

    The rapid increase of available scientific knowledge is largely due to the introduction of novel research strategies. The application of these strategies, both in fundamental and in translational scientific research, leads to bursts of technological innovations. In order to fulfill the justified public request for sustainability of technological innovations that contribute to the shaping of the future, increasing attention should be given to science-based technology and policy assessment. These requests are illustrated by benefit/risk evaluations of relevance for the use of genetic engineering as an efficient and effective research strategy. Expected benefits of a responsibly planned introduction of GM crops are outlined as a prospective example for the guiding theme "Biotechnology for sustainability of human society".

TAMI created a structured dialogue between technology assessment experts and policymakers on current methodologies and their impact on policymaking. The TAMI team explored and assessed the whole spectrum of methodologies from the "classical" to the "interactive/participatory" and "communicative," identified good practices in project implementation and set the stage for impact evaluation based on objective criteria. Finally this report offers a series of policy recommendations based on the findings of the project. Science, Society and Policy, are three areas that technology assessment functions within and works for; this book is an attempt to improve the interaction amongst them for a more socially and economically sustainable Science and Technology p...

    Gadimova, Sharafat

    Capacity-building efforts in space science and technology are a major focus of the activities of the Office of Outer Space Affairs. Such efforts include providing support to the regional centres for space science and technology education, affiliated to the United Nations, whose goal is to develop, through in-depth education, an indigenous capability for research and applications in the core disciplines of: (a) remote sensing and geographical information systems; (b) satellite communications; (c) satellite meteorology and global climate; and (d) space and atmospheric sciences and data management. The regional centres are located in Morocco and Nigeria for Africa, in Brazil and Mexico for Latin America and the Caribbean and in India for Asia and the Pacific. The overall policy-making body of each Centre is its Governing Board and consists of member States (within the region where the Centre is located), that have agreed, through their endorsement of the Centre's agreement, to the goals and objectives of the Centre. The United Nations Programme on Space Applications, with the support of prominent educators, has developed standard education curricula, which were adopted by the Centres for teaching each of the four core disciplines. Within the framework of the International Committee on global navigation satellite systems (ICG), which is established as an informal body for the purpose of promoting the use and application of global navigation satellite systems (GNSS) on a global basis, the Regional Centres will also be acting as the ICG Information Centres. The ICG Information Centres aim to foster a more structured approach to information exchange in order to fulfil the reciprocal expectations of a network between ICG and Regional Centres.

  15. Intellectual and Technological Development of Regions: Challenges and Ways to Address them

    Directory of Open Access Journals (Sweden)

    Vladimir Stepanovich Bochko

    2017-12-01

    Full Text Available The article reveals the issues of intellectual and technological development of the country and regions. The author shows that growing number of employees with higher education is not accompanied by a proportionate increase in the technology level of the economy. This is due to the change of the purpose of higher education. Gradually, the higher education has become a tool ensuring a common cultural level of the population. The author analyses major reasons for a weak contribution of an increasing number of employees with higher education to the technological growth. Professional researchers and employees from various types of industries should be considered as producers of intellectual and technological development. I suggest calling them the generators of intelligent technologies. The author’s interpretation of the concept of «scientific and research education» implies not only the development of creative abilities, but also the understanding of the causes and consequences of natural and social processes as well as critical reflection on these processes. Scientific and research education is emerging directly from research activity. The support of scientific and research education keeps in the society the desire of scientific breakthroughs. The author has revealed the negative tendencies in science. They are related to a considerable decrease in research and development as well as to the withdrawal of the Russian business from the sphere of scientific research. I conclude that there is an urgent need to invest into science. This will result in scientific and technological progress, which would develop the society and increase the productivity of social activities.

  16. A comparison of regional and global catastrophic hazards associated with energy technologies

    International Nuclear Information System (INIS)

    Heising, C.D.; Inhaber, H.

    1984-01-01

    The paper reviews some of what is known about the relative catastrophic hazards, on both a regional and global level, of energy technologies, and proposes a logical framework for their comparison. A review of the Inhaber study results is made indicating the relative position of overall nuclear power related risks. Then, concentration is placed on describing the catastrophic and global hazards of energy technologies. Regionally catastrophic hazards include sabotage and other malicious human activities, in addition to severe accidents caused inadvertently by man, such as fires, reactor core damage events, chemical and poisonous gas releases, fuel storage fires and explosions. Global risks include such hazards as nuclear proliferation, CO 2 buildup, oil shortages and possible national conflicts over dwindling energy fuels. The conclusion is drawn that both regional and global catastrophic risks must be taken into consideration in making energy decisions, and that further study is necessary to better quantify and compare these risks. A simple decision analytic framework for making energy decisions inclusive of catastrophic risks is proposed. (author)

    . They generally have multiple queens per colony, are unicolonial (lacking internest aggression), quickly recruit to food items, thrive in a variety of habitats including disturbed areas, and can be highly aggressive to other ant species (McGlynn 1999). Hawaii’s arthropod fauna evolved in the absence of ants and has been observed by many biologists to be highly vulnerable to displacement by non-native ants. Pacific island biotas have also very likely suffered greatly from displacement by ants. However, in contrast to Hawaii, virtually nothing has been published on effects of non-native ants on native arthropod fauna elsewhere on Pacific islands, with the exception of the Galapagos archipelago, which may have at least four species of endemic ants (Lubin 1984, Nishida and Evenhuis 2000) and New Caledonia (Jourdan et al. 2001, Le Breton et al. 2005). In addition, many ant species in the Pacific have long been a nuisance for humans, and significant agricultural impacts have occurred from ants tending hemipteran insects of crop plants.

    In the past, significant research efforts have been directed towards understanding how severe geomagnetic storms affect the near-Earth space environment. From this research, we have learned that many technologies are affected by these severe space weather events. The 2015 St. Patrick's Day geomagnetic storm has provided a great opportunity to analyze three selected space weather phenomena that adversely impact modern technologies; (1) Geomagnetically Induced Currents (GICs), (2) increased thermospheric mass density, and (3) the occurrence of Equatorial Plasma Bubbles (EPBs). The serious effects of GICs on power grids in the high-latitude regions is well known. Recent research has indicated that the equatorial region is also susceptible to increased GIC activity due to the equatorial electrojet. Thus, an examination of the equatorial magnetometer data during the St. Patrick's Day storm will be presented. It is also well understood that during geomagnetic storms, the thermospheric mass density at a given altitude increases due to the increase in Joule heating in the high-latitude regions. As a consequence of this, low-Earth orbiting satellites and space debris experience increased atmospheric drag. Changes in atmospheric drag causes orbits to be perturbed, resulting in less accurate orbit predictions. An investigation of the orbits of several low-Earth orbiting satellites will be presented and discussed in the context of collision avoidance, as part of the ongoing space debris problem. Finally, Equatorial Plasma Bubbles (EPBs) are a common phenomenon in the nighttime low-latitude ionosphere. EPBs are known to cause random fluctuations (i.e., scintillations) in the amplitude and phase of trans-ionospheric radio signals. While EPBs have been reported during both geomagnetically quiet and disturbed periods, research clearly indicates that the occurrence of EPBs is dependent on the geomagnetic activity level. The occurrence of EPBs around the world will be presented

    The primary objective of this paper is to present the results of the study of the effects of varying ionospheric conditions on the GPS signal tracking in the southern polar region. In the first stage of this study, the data collected by the OSU/USGS team in October-November 2003 within the TAMDEF (Transantarctic Mountains Deformation) network were used together with some IGS Antarctic stations to study the effect of severe ionospheric storms on GPS hardware. Note that TAMDEF is a joint USGS/OSU project with the primary objective of measuring crustal motion in the Transantarctic Mountains of Southern Victoria Land using GPS techniques. This study included ten Antarctic stations equipped with different dual-frequency GPS hardware, and the data were evaluated for two 24-hour periods of severe ionospheric storm (2003/10/29) and moderate ionospheric conditions (minor storm of 2003/11/11). The results of this study were presented at the LAG Assembly in Cairns, Australia (Grejner-Brzezinska et al., 2005). Additional tests, in a more controlled environment, were carried out at the US Antarctic station, McMurdo, between January 10 and February 6, 2006, under varying ionospheric conditions, where several different types of receivers were connected to the same antenna located on the rooftop of the Crary Laboratory (the primary test site). In this scenario, each antenna was subject to identical ionospheric effects during each day of the test, and no spatial decorrelation effects were present, as seen in the previous study, due to the spatial separation of the receivers tested. It should be noted, however, that no moderate or severe ionospheric storms occurred during the experiment, so, unfortunately, this type of conditions was not tested here. The test was repeated with different receivers connected to different antenna types; a total of four 5-day sessions were carried out. The following receiver types were used at the primary site: Trimble 5700, Ashtech Z-Surveyor, JNS Euro

    Frey, H Christopher; Zhai, Haibo; Rouphail, Nagui M

    2009-11-01

    This study presents a methodology for estimating high-resolution, regional on-road vehicle emissions and the associated reductions in air pollutant emissions from vehicles that utilize alternative fuels or propulsion technologies. The fuels considered are gasoline, diesel, ethanol, biodiesel, compressed natural gas, hydrogen, and electricity. The technologies considered are internal combustion or compression engines, hybrids, fuel cell, and electric. Road link-based emission models are developed using modal fuel use and emission rates applied to facility- and speed-specific driving cycles. For an urban case study, passenger cars were found to be the largest sources of HC, CO, and CO(2) emissions, whereas trucks contributed the largest share of NO(x) emissions. When alternative fuel and propulsion technologies were introduced in the fleet at a modest market penetration level of 27%, their emission reductions were found to be 3-14%. Emissions for all pollutants generally decreased with an increase in the market share of alternative vehicle technologies. Turnover of the light duty fleet to newer Tier 2 vehicles reduced emissions of HC, CO, and NO(x) substantially. However, modest improvements in fuel economy may be offset by VMT growth and reductions in overall average speed.

    Determine the viability of a remote diagnosis system implemented to provide health care to remote and scattered populations in Paraguay. The study was conducted in all regional and general hospitals in Paraguay, and in the main district hospitals in the country's 18 health regions. Clinical data, tomographic images, sonography, and electrocardiograms (ECGs) of patients who needed a diagnosis by a specialized physician were entered into the system. This information was sent to specialists in diagnostic imaging and in cardiology for remote diagnosis and the report was then forwarded to the hospitals connected to the system. The cost-benefit and impact of the remote diagnosis tool was analyzed from the perspective of the National Health System. Between January 2014 and May 2015, a total of 34 096 remote diagnoses were made in 25 hospitals in the Ministry of Health's telemedicine system. The average unit cost of remote diagnosis was US$2.6 per ECG, tomography, and sonography, while the unit cost of "face-to-face" diagnosis was US$11.8 per ECG, US$68.6 per tomography, and US$21.5 per sonography. As a result of remote diagnosis, unit costs were 4.5 times lower for ECGs; 26.4 times lower for tomography, and 8.3 times lower for sonography. In monetary terms, implementation of the remote diagnosis system during the 16 months of the study led to average savings of US$2 420 037. Paraguay has a remote diagnosis system for electrocardiography, tomography, and sonography, using low-cost information and communications technologies (ICTs) based on free software that is scalable to other types of remote diagnostic studies of interest for public health. Implementation of remote diagnosis helped to strengthen the integrated network of health services and programs, enabling professionals to optimize their time and productivity, while improving quality, increasing access and equity, and reducing costs.

  3. Impacts of Climate Policy on Regional Air Quality, Health, and Air Quality Regulatory Procedures

    Thompson, T. M.; Selin, N. E.

    2011-12-01

    Both the changing climate, and the policy implemented to address climate change can impact regional air quality. We evaluate the impacts of potential selected climate policies on modeled regional air quality with respect to national pollution standards, human health and the sensitivity of health uncertainty ranges. To assess changes in air quality due to climate policy, we couple output from a regional computable general equilibrium economic model (the US Regional Energy Policy [USREP] model), with a regional air quality model (the Comprehensive Air Quality Model with Extensions [CAMx]). USREP uses economic variables to determine how potential future U.S. climate policy would change emissions of regional pollutants (CO, VOC, NOx, SO2, NH3, black carbon, and organic carbon) from ten emissions-heavy sectors of the economy (electricity, coal, gas, crude oil, refined oil, energy intensive industry, other industry, service, agriculture, and transportation [light duty and heavy duty]). Changes in emissions are then modeled using CAMx to determine the impact on air quality in several cities in the Northeast US. We first calculate the impact of climate policy by using regulatory procedures used to show attainment with National Ambient Air Quality Standards (NAAQS) for ozone and particulate matter. Building on previous work, we compare those results with the calculated results and uncertainties associated with human health impacts due to climate policy. This work addresses a potential disconnect between NAAQS regulatory procedures and the cost/benefit analysis required for and by the Clean Air Act.

    Centralized wastewater management system is the modern day waste management practice, but the high cost and stringent requirements for the construction and operation have made it less attractive in the under-resourced regions of the world. Considering these challenges, the use of decentralized wastewater management system, on-site treatment system, as an appropriate technology for domestic wastewater treatment is hereby advocated. Adopting this technology helps save money, protects home owners' investment, promotes better watershed management, offers an appropriate solution for low-density communities, provides suitable alternatives for varying site conditions and furnishes effective solutions for ecologically sensitive areas. In the light of this, an overview of the on-site treatment scheme, at the laboratory scale, pilot study stage, and field trials was conducted to highlight the operational principles' strength and shortcomings of the scheme. The operational requirements for the establishing and operation of the scheme and best management practice to enhance the performance and sustenance were proffered.

    1993-12-31

    The use of biomass as primary fuel for power and steam production using modern conversion technology such as the Biomass Integrated Gas Turbine/Combined Cycle (BIG/CC) has both technical and commercial potential. Brazil is implementing a BIG/CC Demonstration Plant to burn wood from eucalyptus short rotation forest and to test sugar cane bagasse as feedstock. The purpose of this project is to demonstrate the commercial viability of using biomass as a feedstock for power generation, its suitability for applications in developing countries, and the possibilities it offers for commercial activities in regions which currently have a low level of economic activities. The purpose of this paper is to show the potential applicability of this technology in the sugar cane industries of Developing Countries such as Brazil. The same quantity of sugar cane already processed in each sugar mill can produce sizable quantities of electric power at competitive costs, in addition to the traditional products -- sugar and/or ethanol, which will cause an economical impact, duplicating the revenue of these industries. The application of the BIG/CC technology in the Sugar Cane Industry may lead to the following scenario in developing countries: (1) power shall be produced at very competitive prices by specialized private firms associated with sugar mills; (2) plant sizes will be smaller -- 15 to 100 MW -- when based on biomass, a compared to large fossil fuel plants now prevailing; (3) ethanol and sugar production costs will be reduced due to more efficient and economical processes and due to the additional revenue from power production; (4) becoming more competitive with gasoline, ethanol production tends to increase, which will influence the automobile industry and improve the quality of life in big cities.

    Full Text Available This article reports on the implementation of clickers to improve the success rate of first-year mathematics students. There were 105 students registered in this course, in a university of technology in South Africa. In order to do this, an orientation test in the form of a paper-based assessment was first conducted to determine what students already knew. About 21.9% of the students did not take the test and 20% did not pass it. These results raised concerned. Thereafter students were taught. After four weeks they were evaluated on their understanding of the concept taught in class. Results did not improve much, as 48.6% of the students did not pass the test. Therefore, a technology-engagement teaching strategy (TETS using clicker technology was developed and implemented in order to improve the pass rate. Weekly continuous assessments or diagnostic tests were conducted in order to establish the changes in students’ academic performance. A survey questionnaire was administered after the teaching and learning of incorporating clickers. This questionnaire also examined students’ perspective on the usefulness of clickers in teaching and learning. The results showed that the effective implementation of clickers with the integration of a TETS improved students’ success rate.

  14. The regional economic impact of oil and gas extraction in Texas

    International Nuclear Information System (INIS)

    Lee, Jim

    2015-01-01

    This paper empirically investigates the regional economic impact of oil and gas extraction in Texas during the recent shale oil boom. Regressions with county-level data over the period 2009–2014 support smaller multiplier effects on local employment and income than corresponding estimates drawn from popular input–output-based studies. Economic impacts were larger for extraction from gas wells than oil wells, while the drilling phase generated comparable impacts. Estimates of economic impacts are greater in a dynamic spatial panel model that allows for spillover effects across local economies as well as over time. - Highlights: • Economic impacts and multiplier effects differ between oil and gas wells in Texas. • Interactions among local economies raise employment and income effects. • Impacts persist over time, raising the long-run multipliers. • Greater economic impacts from newly drilled wells than legacy wells.

  15. Introducing Sectoral Models into Regional Management: An Assessment of Regulatory Impacts on the Economy

    Directory of Open Access Journals (Sweden)

    Voloshenko K.Yu.

    2017-12-01

    Full Text Available Regardless of the geography of regions, management at the regional level, both in Russia and the Baltic Sea countries, faces many challenges. Hence, it is necessary to search for new effective economic management tools, since traditional approaches and modeling practices at the regional level are not suitable for either analysing various types of impact on regional economy (production, market (product, sector, region, or assessment of their consequences and identification of the necessary measures in any given economic conditions. The authors construct sectoral models to assess regulatory impacts on regional economic performance. Assessments of regulatory impacts on product value chains, economic sectors, and regions as a whole show good repeatability, which makes it possible to provide a rationale for economic decision-making. The authors propose new sectoral models using the Kaliningrad region as an example. The models are used in a comprehensive analysis of conditions for a GRP growth resulting from an increase in sectoral contributions. To this end, the study uses the well-known approaches of simulation modelling, as well as qualitative and quantitative methods in combination with economic-mathematical optimisation models. The article presents a pilot model of regulatory impacts for selected sectors of the Kaliningrad economy. The developed and tested models suggest that a rationale for economic decision-making and consequent actions should be based on the assessment of the impact of different groups of external, internal, and independent factors on value chains, based on the criterion of optimal factor income. In conclusion, the authors offer recommendations for using the proposed models in business, public administration and regional economic modeling.

    Marks, Lawrence B.; Light, Kim L.; Hubbs, Jessica L.; Georgas, Debra L.; Jones, Ellen L.; Wright, Melanie C.; Willett, Christopher G.; Yin Fangfang

    2007-01-01

    Purpose: To assess the impact of new technologies on deviation rates in radiation therapy (RT). Methods and Materials: Treatment delivery deviations in RT were prospectively monitored during a time of technology upgrade. In January 2003, our department had three accelerators, none with 'modern' technologies (e.g., without multileaf collimators [MLC]). In 2003 to 2004, we upgraded to five new accelerators, four with MLC, and associated advanced capabilities. The deviation rates among patients treated on 'high-technology' versus 'low-technology' machines (defined as those with vs. without MLC) were compared over time using the two-tailed Fisher's exact test. Results: In 2003, there was no significant difference between the deviation rate in the 'high-technology' versus 'low-technology' groups (0.16% vs. 0.11%, p = 0.45). In 2005 to 2006, the deviation rate for the 'high-technology' groups was lower than the 'low-technology' (0.083% vs. 0.21%, p = 0.009). This difference was caused by a decline in deviations on the 'high-technology' machines over time (p = 0.053), as well as an unexpected trend toward an increase in deviations over time on the 'low-technology' machines (p = 0.15). Conclusions: Advances in RT delivery systems appear to reduce the rate of treatment deviations. Deviation rates on 'high-technology' machines with MLC decline over time, suggesting a learning curve after the introduction of new technologies. Associated with the adoption of 'high-technology' was an unexpected increase in the deviation rate with 'low-technology' approaches, which may reflect an over-reliance on tools inherent to 'high-technology' machines. With the introduction of new technologies, continued diligence is needed to ensure that staff remain proficient with 'low-technology' approaches

    Full Text Available Research studies have proven that place-based/regional branding methods have a positive effect on brand equity and economic benefits for companies. However, very small or specific regions may be confusing to consumers, so conjunctive labeling – or the process of advertising both a larger region and the sub-region of origin for a product – is suggested as a remedy for this situation. This study analyzes the impact of conjunctive labeling by comparing two national samples of consumers, before and two years after, conjunctive wine labeling was introduced in Sonoma County. The results show a higher awareness for both Sonoma County and its sub appellations (AVAs after conjunctive labeling was introduced than before. This demonstrates the potential benefit of associating sub-regional appellations with larger wine regions.

    2014-05-01

    Land-use development planning is carried out in order to create a favourable environment for human life, sustainable socioeconomic and spatial development. Landscape planning is an important part of land-use development that aims to meet the fundamental principles of sustainable development. Geographic Information Systems (GIS) is a fundamental tool to make a better landscape planning at different territorial levels, providing data and maps to support decision making. The objective of this work is to create spatio-temporal, territorial and ecological model of development of Volyn region (Ukraine). It is based on existing spatial raster and vector data and includes the analysis of territory dynamics as the aspects responsible for it. A spatial analyst tool was used to zone the areas according to their environmental components and economic activity. This analysis is fundamental to define the basic parameters of sustainability of Volyn region. To carry out this analysis, we determined the demographic capacity of districts and the analysis of spatial parameters of land use. On the basis of the existing natural resources, we observed that there is a need of landscape protection and integration of more are natural areas in the Pan-European Ecological Network. Using GIS technologies to landscape planning in Volyn region, allowed us to identify, natural areas of interest, contribute to a better resource management and conflict resolution. Geographic Information Systems will help to formulate and implement landscape policies, reform the existing administrative system of Volyn region and contribute to a better sustainable development.

    2009-12-01

    This paper describes activities and results of melding basic scientific research in remote sensing with applied science and technology development and infusion to implement regional flood pilot programs in Sub-Saharan Africa and the Caribbean Region. These regional flood pilots support local and national agency involvement in emergency response and humanitarian assistance activities using orbital, sub-orbital, and in-situ sensors combined with predictive models and socio-economic data to form a cohesive, interoperable set of systems that cover the full cycle of disaster mitigation, warning, response, and recovery for societal benefit. Global satellite coverage is coordinated through the Committee on Earth Observation Satellites (CEOS) in conjunction with the United Nations Space Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER). Other international non-government organizations plus regional and local agencies all play individual roles in exploring the science results, applying the observations and model outputs to form geo-referenced maps that provide improved situational awareness and environmental intelligence for disaster management. The improvements to flood forecast and nowcast outputs include higher resolution drainage and hydrology mapping, improved retrievals for microwave data for soil moisture, plus improved validation from regional ground truth databases. Flow gauge and river depth archive data from local assets provide improved validation of flood model results. Incorporation of atmospheric correction using ground truth data from calibration and validation sites enables better detection and classification of plant species identification and plant stress. Open Geospatial Consortium (OGC) standards for Sensor Web Enablement (SWE) are implemented to provide internet access to satellite tasking, data processing, and distribution/notification in addition to model outputs and other local and regional data sets

    One of the main considerations in designing environmental policy is the impact of policy instruments on the timing of firms' investment decisions with respect to energy-saving technologies. This paper analyzes the impact of environmental taxes and quotas on the timing of adoption when (i) the rate at which new, improved energy-efficient technologies become available, is uncertain, and (ii) the investment decision is (at least partially) irreversible. We find that neither policy instrument is unambiguously preferred to the other when it comes to stimulating early adoption of new technologies.

  5. Study of the global and regional climatic impacts of ENSO magnitude using SPEEDY AGCM

    KAUST Repository

    Dogar, Muhammad Mubashar

    2017-03-09

    ENSO is considered as a strong atmospheric teleconnection that has pronounced global and regional circulation effects. It modifies global monsoon system, especially, Asian and African monsoons. Previous studies suggest that both the frequency and magnitude of ENSO events have increased over the last few decades resulting in a need to study climatic impacts of ENSO magnitude both at global and regional scales. Hence, to better understand the impact of ENSO amplitude over the tropical and extratropical regions focussing on the Asian and African domains, ENSO sensitivity experiments are conducted using ICTPAGCM (‘SPEEDY’). It is anticipated that the tropical Pacific SST forcing will be enough to produce ENSO-induced teleconnection patterns; therefore, the model is forced using NINO3.4 regressed SST anomalies over the tropical Pacific only. SPEEDY reproduces the impact of ENSO over the Pacific, North and South America and African regions very well. However, it underestimates ENSO teleconnection patterns and associated changes over South Asia, particularly in the Indian region, which suggests that the tropical Pacific SST forcing is not sufficient to represent ENSO-induced teleconnection patterns over South Asia. Therefore, SST forcing over the tropical Indian Ocean together with air–sea coupling is also required for better representation of ENSO-induced changes in these regions. Moreover, results obtained by this pacemaker experiment show that ENSO impacts are relatively stronger over the Inter-Tropical Convergence Zone (ITCZ) compared to extratropics and high latitude regions. The positive phase of ENSO causes weakening in rainfall activity over African tropical rain belt, parts of South and Southeast Asia, whereas, the La Niña phase produces more rain over these regions during the summer season. Model results further reveal that ENSO magnitude has a stronger impact over African Sahel and South Asia, especially over the Indian region because of its significant

    2016-12-01

    Air leakage is responsible for about 1.1 quads of energy or 6% of the total energy used by commercial buildings in the US. Consequently, infiltration and exfiltration are among the largest envelope-related contributors to the heating, ventilation, and air conditioning loads in commercial buildings. New air sealing technologies have recently emerged that aim to improve the performance of air barrier systems by simplifying their installation procedure. LIQUIDARMORTM CM Flashing and Sealant is an example of these new advanced material technologies. This technology is a spray-applied sealant and liquid flashing and can span gaps that are up to ¼ in. wide without a supporting material. ORNL verified the performance of LIQUIDARMORTM CM with field tests and energy simulations from a building in which LIQUIDARMORTM CM was one of components of the air barrier system. The Homeland Security Training Center (HTC) at the College of DuPage in Glen Ellyn, IL, served as the demonstration site. Blower door test results show the average air leakage rate in the demonstration site to be 0.15 cfm/ft2 at 1.57 psf, or 63% lower than the 0.4 cfm at 1.57 psf specified in the 2015 International Energy Conservation Code (IECC). According to simulation results, HTC lowered its annual heating and cooling cost by about $3,000 or 9% compared to a similar building that lacked an air barrier system. This demonstration project serves as an example of the level of building envelope airtightness that can be achieved by using air barrier materials that are properly installed, and illustrates the energy and financial savings that such an airtight envelope could attain.

    Full Text Available Tamar ShochatDepartment of Nursing, Faculty of Social Welfare and Health Sciences, University of Haifa, Haifa, IsraelAbstract: Although the physiological and psychological mechanisms involved in the development of sleep disorders remain similar throughout history, factors that potentiate these mechanisms are closely related to the "zeitgeist", ie, the sociocultural, technological and lifestyle trends which characterize an era. Technological advancements have afforded modern society with 24-hour work operations, transmeridian travel and exposure to a myriad of electronic devices such as televisions, computers and cellular phones. Growing evidence suggests that these advancements take their toll on human functioning and health via their damaging effects on sleep quality, quantity and timing. Additional behavioral lifestyle factors associated with poor sleep include weight gain, insufficient physical exercise and consumption of substances such as caffeine, alcohol and nicotine. Some of these factors have been implicated as self-help aids used to combat daytime sleepiness and impaired daytime functioning. This review aims to highlight current lifestyle trends that have been shown in scientific investigations to be associated with sleep patterns, sleep duration and sleep quality. Current understanding of the underlying mechanisms of these associations will be presented, as well as some of the reported consequences. Available therapies used to treat some lifestyle related sleep disorders will be discussed. Perspectives will be provided for further investigation of lifestyle factors that are associated with poor sleep, including developing theoretical frameworks, identifying underlying mechanisms, and establishing appropriate therapies and public health interventions aimed to improve sleep behaviors in order to enhance functioning and health in modern society.Keywords: sleep, technology, lifestyle, behavior

    Diabetes and its related complications and comorbidities (C&Cs) represent a significant and increasing healthcare burden. Absence of a systematic manner to evaluate value propositions of technologies from various stakeholders' perspectives impedes the best uses of current and emerging technologies. A system dynamics methodology was used to develop a comprehensive causal simulator of the U.S. population and give proof of principle that entire portfolios of present and future technologies can be evaluated for direct and indirect impacts. An explicit semiquantitative methodology was used for surveying, prioritizing, and grouping C&Cs, patient subgroups, and technologies, utilizing diverse publicly available clinical literature. The resulting model simulates the incidence and prevalence of diabetes and 10 of its most commonly associated C&Cs, reflecting their interrelated upstream and downstream relationships. The simulator enables systematic evaluation of tens of thousands of potential combinations of emerging technologies and technology leverage points that can be used to improve patient outcomes and guide technology investments. Feasibility was demonstrated through single, pair-wise, and targeted analyses of technologies. This effort demonstrated the feasibility of linking complex, interconnected disease states, impact points, outcomes, and interventions with a variety of outcome metrics, to an extent greater than existing models developed for other purposes. The project demonstrated the ability to identify priority technologies and pipeline therapies and leverage points among diabetes interventions. It demonstrated more effective knowledge management of diverse information essential for formulating strategy that could be applied in a wide range of therapeutic applications and technology innovation uses.

    Full Text Available In situ coal gasification technology (Underground Coal Gasification–UCG– is an alternative to the traditional exploitation, due to it allows to reach the today’s inaccessible coal reserves’ recovery, to conventional mining technologies. In this article I answer the question on how the today’s reserves available volume, can be increased, given the possibility to exploit further and better the same resources. Mining is an important wealth resource in Colombia as a contributor to the national GDP. According with the Energy Ministry (Ministerio de Minas y Energía [1] mining has been around 5% of total GDP in the last years. This is a significant fact due to the existence of a considerable volume of reserves not accounted for (proved reserves at year 2010 were 6.700 million of tons.

    To assess the effect of technology on sport, the performance statistics for four disciplines were analysed: the 100-m sprint, pole vault, javelin, and cycling. The concept of a performance improvement index was developed to allow comparison between athletes and between sports with a higher index indicating a greater improvement in the sport. The following performance improvement indices were found: 100-m sprint, 24% over 108 years; pole vault, 86% over 94 years; javelin, 95% over 76 years; 4-km individual pursuit, 35% over 32 years; one-hour cycling record, 221% over 111 years. Around 4% of the index for the sprint was attributed to tighter, aerodynamic clothing, suggesting that general athletic improvement in sprint-type events has been around 20%. Technological developments in simple equipment such as the pole vault or javelin were seen to affect the index by around 30%, while the index associated with aerodynamic improvements in the one-hour record was around 100%. It is concluded that the performance improvement index could be extended to amateur as well as elite sport where distance or time is used as a measure of performance.

    Full Text Available In the growing business competitiveness TQM (Total Quality Management and TM (Technology Management practices have become important for organizational success. TQM fosters business excellence while TM helps to deal with process and product related technological challenges. However, in literature TM has received little consideration with TQM. This paper is a research study that attempts to identify any combined relationship of both concepts with OP (Organizational Performance while taking into account different organizational contextual factors including ISO-9001 certification. Responses from 86 different organizations in Pakistan are collected through questionnaire survey and random sampling. Statistical analysis shows that OP is positively associated to TQM and TM. Results of this study indicate the significance of ISO-9001 certification for TQM but do not support it for OP. It is also observed that organizations of private sector are significantly better in TQM and TM practices, so in OP, in comparison to government or public sector organizations. The study contributes to explore and augment both practices for implementation to improve OP.

    Life Cycle Assessment (LCA) has been used in quantifying the environmental impacts of materials, processes, products, or systems across their entire lifespan from creation to disposal. To evaluate the environmental impact of advancing technology, Life Cycle Assessment with Technological Advances over Time (LCA-TAT) incorporates technology improvements within the traditional LCA framework. In this paper, the LCA-TAT is applied to quantify the environmental impacts of ethanol production using cellulosic biomass as a feedstock through the simultaneous saccharification and co-fermentation (SSCF) process as it improves over time. The data for the SSCF process are taken from the Aspen Plus ® simulation developed by the National Renewable Energy Lab (NREL). The Environmental Fate and Risk Assessment Tool (EFRAT) is used to calculate the fugitive emissions and SimaPro 7.1 software is used to quantify the environmental impacts of processes. The impact indicators of the processes are calculated using the Eco-indicator 95 method; impact categories analyzed include ozone layer depletion, heavy metals, carcinogens, summer smog, winter smog, pesticides, greenhouse effect, acidification, and eutrophication. Based on the LCA-TAT results, it is found that removal of the continuous ion exchange step within the pretreatment area increases the environmental impact of the process. The main contributor to the increase in the environmental impact of the process is the heavy metal indicator. In addition, a sensitivity analysis is performed to identify major inputs and outputs that affect environmental impacts of the overall process. Based on this analysis it is observed that an increase in waste production and acid use have the greatest effect on the environmental impacts of the SSCF process. Comparing economic analysis with projected technological advances performed by NREL, the improvement in environmental impact was not matched by a concomitant improvement in economic performance. In

    Marine and hydrokinetic energy (MHK) and offshore wind devices are being developed and deployed in U.S. and international waters. Electric current flowing through subsea transmission cables associated with these devices will generate electromagnetic fields (EMF), which may interact with, and potentially impact, marine fishes. Some marine fishes can detect electric and/or magnetic fields and use them to navigate, orientate, and sense prey, mates and predators. Over the past five years there have been multiple comprehensive reviews and studies evaluating the potential vulnerability of marine fishes to EMF produced by MHK devices. Most documented effects involve sub-lethal behavioral responses of individual fish when in close proximity to EMF (e.g., fish being repelled by or attracted to fields). These reviews reach conclusions that the current state of research on this topic is still in its infancy and evaluations of potential impacts are associated with great uncertainty. A variety of MHK technologies are likely to be considered for deployment offshore of the Hawaiian Islands, and there is a need to be able to better predict and assess potential associated environmental impacts. The goal of this study was to provide a complementary piece to these previous reviews (e.g., Normandeau et al. 2011) by focusing on marine fish species in the Hawaii region. We compiled the relevant available information, then prioritized fish species as candidates for various paths of future research. To address this, we first developed a list of Hawaii Region Focal Species, which included fishes that are more likely to be sensitive to EMF. We then compiled species-specific information available in the literature on their sensitivity to EMF, as well as life history, movement and habitat use information that could inform an analysis of their likelihood of encountering EMF from subsea cables associated with MHK devices. Studies have only documented EMF sensitivity in 11 of the marine fish

    This paper examines the impacts of access to extension services and cooperative membership on technology adoption, asset ownership and poverty using household-level data from rural Nigeria. Using different matching techniques and endogenous switching regression approach, we find that both extension access and cooperative membership have a positive and statistically significant effect on technology adoption and household welfare. Moreover, we find that both extension access and cooperative membership have heterogeneous impacts. In particular, we find evidence of a positive selection as the average treatment effects of extension access and cooperative membership are higher for farmers with the highest propensity to access extension and cooperative services. The impact of extension services on poverty reduction and of cooperatives on technology adoption is significantly stronger for smallholders with access to formal credit than for those without access. This implies that expanding rural financial markets can maximize the potential positive impacts of extension and cooperative services on farmers' productivity and welfare.
