    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected. The gross data are submitted to a thorough review allowing the correction of abnormalities and the reconstitution of missing data. Each index is fashioned to take into account the economic activity in the various regions of the country as represented by each region's population. This demographic information represents a fair approximation of the weight of the regional economic activity. This document presents the calculation methodology of average, minimum and maximum weather indexes with the winter and summer regression equations for the different economical regions of Belgium.

    2010-05-01

    This Methodology Booklet provides a comprehensive review and methodology guiding principles for constructing energy efficiency indicators, with illustrative examples of application to individual countries. It reviews work done by international agencies and national government in constructing meaningful energy efficiency indicators that help policy makers to assess changes in energy efficiency over time. Building on past OECD experience and best practices, and the knowledge of these countries' institutions, relevant sources of information to construct an energy indicator database are identified. A framework based on levels of hierarchy of indicators -- spanning from aggregate, macro level to disaggregated end-use level metrics -- is presented to help shape the understanding of assessing energy efficiency. In each sector of activity: industry, commercial, residential, agriculture and transport, indicators are presented and recommendations to distinguish the different factors affecting energy use are highlighted. The methodology booklet addresses specifically issues that are relevant to developing indicators where activity is a major factor driving energy demand. A companion spreadsheet tool is available upon request.

    Oeien, K.; Sklet, S.

    1999-01-01

    This paper presents a generic methodology for development of risk indicators for petroleum installations and a specific set of risk indicators established for one offshore platform. The risk indicators should be used to control the risk during operation of platforms. The methodology is purely risk-based and the basis for development of risk indicators is the platform specific quantitative risk analysis (QRA). In order to identify high risk contributing factors, platform personnel are asked to assess whether and how much the risk influencing factors will change. A brief comparison of probabilistic safety assessment (PSA) for nuclear power plants and quantitative risk analysis (QRA) for petroleum platforms is also given. (au)

  7. Energy indicators for sustainable development: Guidelines and methodologies

    International Nuclear Information System (INIS)

    2005-04-01

    This publication is the product of an international initiative to define a set of Energy Indicators for Sustainable Development (EISD) and corresponding methodologies and guidelines. The successful completion of this work is the result of an intensive effort led by the International Atomic Energy Agency (IAEA) in cooperation with the United Nations Department of Economic and Social Affairs (UNDESA), the International Energy Agency (IEA), Eurostat and the European Environment Agency (EEA). The thematic framework, guidelines, methodology sheets and energy indicators set out in this publication reflect the expertise of these various agencies, recognized worldwide as leaders in energy and environmental statistics and analysis. While each agency has an active indicator programme, one goal of this joint endeavour has been to provide users with a consensus by leading experts on definitions, guidelines and methodologies for the development and worldwide use of a single set of energy indicators. No set of energy indicators can be final and definitive. To be useful, indicators must evolve over time to fit country-specific conditions, priorities and capabilities. The purpose of this publication is to present one set of EISD for consideration and use, particularly at the national level, and to serve as a starting point in the development of a more comprehensive and universally accepted set of energy indicators relevant to sustainable development. It is hoped that countries will use the EISD to assess their energy systems and to track their progress towards nationally defined sustainable development goals and objectives. It is also hoped that users of the information presented in this publication will contribute to refinements of energy indicators for sustainable development by adding their own unique perspectives to what is presented herein

    2015-12-01

    Full Text Available Today the national security system effectiveness seriously depends on the professional analysis of information and timely forecasts. Thus the efficient methods of forecasting in the sphere of international relations are of current importance for the modern intelligence services. The Indications and Warning Technique that was a key element of forecasting methodology in intelligence until the end of Cold War is estimated in the present article. Is this method still relevant in the contemporary world with its new international order, new security challenges and technological revolution in the data collection and processing? The main conclusion based on the overview of current researches and known intelligence practice is that indicators technique is still relevant for the early warning of national security threats but requires some adaptation to today’s issues. The most important trends in adaptation are supposed to be a creation of broadest possible spectrum of threatens scenarios as well as research of current strategic threatens and corresponding indicators. Also the appropriate software that automates the use of indications technique by the security services is very important. The author believes that the cooperation between intelligence services and academic community can increase the efficiency of the Indications Methodology and of the strategic forecasting as well.

    2016-04-01

    The FP7 project "Climate Information Portal for Copernicus" (CLIPC) is developing an integrated platform of climate data services to provide a single point of access for authoritative scientific information on climate change and climate change impacts. In this project, the Climate Service Center Germany (GERICS) has been in charge of the development of a methodology on how to assess the uncertainties related to climate impact indicators. Existing climate data portals mainly treat the uncertainties in two ways: Either they provide generic guidance and/or express with statistical measures the quantifiable fraction of the uncertainty. However, none of the climate data portals give the users a qualitative guidance how confident they can be in the validity of the displayed data. The need for such guidance was identified in CLIPC user consultations. Therefore, we aim to provide an uncertainty assessment that provides the users with climate impact indicator-specific guidance on the degree to which they can trust the outcome. We will present an approach that provides information on the importance of different sources of uncertainties associated with a specific climate impact indicator and how these sources affect the overall 'degree of confidence' of this respective indicator. To meet users requirements in the effective communication of uncertainties, their feedback has been involved during the development process of the methodology. Assessing and visualising the quantitative component of uncertainty is part of the qualitative guidance. As visual analysis method, we apply the Climate Signal Maps (Pfeifer et al. 2015), which highlight only those areas with robust climate change signals. Here, robustness is defined as a combination of model agreement and the significance of the individual model projections.

  13. Exploring Methodologies and Indicators for Cross-disciplinary Applications

    2015-12-01

    Assessing the impact and benefit of geospatial information is a multidisciplinary task that involves the social, economic and environmental knowledge to formulate indicators and methods. There are use cases that couple the social sciences including economics, psychology, sociology that incorporate geospatial information. Benefit - cost analysis is an empirical approach that uses money as an indicator for decision making. It is a traditional base for a use case and has been applied to geospatial information and other areas. A new use case that applies indicators is Meta Regression analysis, which is used to evaluate transfers of socioeconomic benefits from different geographic regions into a unifying statistical approach. In this technique, qualitative and quantitative variables are indicators, which provide a weighted average of value for the nonmarket good or resource over a large region. The expected willingness to pay for the nonmarket good can be applied to a specific region. A third use case is the application of Decision Support Systems and Tools that have been used for forecasting agricultural prices and analysis of hazard policies. However, new methods for integrating these disciplines into use cases, an avenue to instruct the development of operational applications of geospatial information, are needed. Experience in one case may not be broadly transferable to other uses and applications if multiple disciplines are involved. To move forward, more use cases are needed and, especially, applications in the private sector. Applications are being examined across a multidisciplinary community for good examples that would be instructive in meeting the challenge. This presentation will look at the results of an investigation into directions in the broader applications of use cases to teach the methodologies and use of indicators that have applications across fields of interest.

    1994-01-01

    Biological methods of water quality evaluation today form an integral part of environmental monitoring and permit to continuously monitor the condition of aquatic ecosystems. They indicate both improvements in water quality following redevelopment measures, and the sometimes insidious deterioration of water quality. This book on biological indication in aquatic ecosystems is a compendium of measurement and evaluation techniques for limnic systems by means of biological parameters. At present, however, an intense discussion of biological evaluation techniques is going on, for one thing as a consequence of the German reunification and the need to unify evaluation techniques, and for another because of harmonizations within the European Community.

  3. Vulnerability curves vs. vulnerability indicators: application of an indicator-based methodology for debris-flow hazards

    Science.gov (United States)

    Papathoma-Köhle, Maria

    2016-08-01

    The assessment of the physical vulnerability of elements at risk as part of the risk analysis is an essential aspect for the development of strategies and structural measures for risk reduction. Understanding, analysing and, if possible, quantifying physical vulnerability is a prerequisite for designing strategies and adopting tools for its reduction. The most common methods for assessing physical vulnerability are vulnerability matrices, vulnerability curves and vulnerability indicators; however, in most of the cases, these methods are used in a conflicting way rather than in combination. The article focuses on two of these methods: vulnerability curves and vulnerability indicators. Vulnerability curves express physical vulnerability as a function of the intensity of the process and the degree of loss, considering, in individual cases only, some structural characteristics of the affected buildings. However, a considerable amount of studies argue that vulnerability assessment should focus on the identification of these variables that influence the vulnerability of an element at risk (vulnerability indicators). In this study, an indicator-based methodology (IBM) for mountain hazards including debris flow (Kappes et al., 2012) is applied to a case study for debris flows in South Tyrol, where in the past a vulnerability curve has been developed. The relatively "new" indicator-based method is being scrutinised and recommendations for its improvement are outlined. The comparison of the two methodological approaches and their results is challenging since both methodological approaches deal with vulnerability in a different way. However, it is still possible to highlight their weaknesses and strengths, show clearly that both methodologies are necessary for the assessment of physical vulnerability and provide a preliminary "holistic methodological framework" for physical vulnerability assessment showing how the two approaches may be used in combination in the future.

    International Nuclear Information System (INIS)

    Osorio Velez, Luis Fernando; Pineda Correa, Marcelena

    2000-01-01

    The investigation mainly responds to the necessity of developing a methodology that allows getting indicators to make easier the process of making decisions in the environmental administration field. The elaboration was relied on the support of the Corporacion Autonoma Regional Rionegro - Nare CORNARE in Antioquia - Colombia, through a subscribed agreement between this entity and the authors. The development of the investigation was carried out in two parts: the first involves the search of methodological paths for the evaluation and selection of applicable indicators to basins, Through the creation of parameters that allow qualifying these indicators in direct form; this is followed by a statistical treatment that allows selecting indicators in a rational way. For application purposes, some criterions are defined in a such way that the selected indicators can be evaluated; with these criterions the matrix is constructed; this allows to view and qualify the indicators, starting from ranges and scales previously defined; once the evaluation and qualification matrix are carried out, the selection process is begun from multivariate analysis. The second part consists in the methodology application expounded to a pattern of indicators previously defined and a determined territory (Basin of the Chachafruto Stream, Rionegro - Antioquia - Colombia); starting from the listing of the whole reported indicators in the consulted literature, the ability of themselves to reflex the basin problems is analyzed, based on parameters such as local contextualization and focuses of the topic. Once the first selection is done, the indicators are submitted to the qualification and evaluation matrix and its results are analyzed by multivariate analysis, in order to condense the environmental indicators to be used. Subsequently, for the evaluation of selected indicators, it is necessary to compile diverse thematic information and to identify the existent databases for the select territory

  11. How methodological issues affect the energy indicator results for different electricity generation technologies

    International Nuclear Information System (INIS)

    Modahl, Ingunn Saur; Raadal, Hanne Lerche; Gagnon, Luc; Bakken, Tor Haakon

    2013-01-01

    The aim of this paper is to improve the basis for the comparison of energy products. The paper will discuss important methodological issues with regard to various energy indicators and it will, by means of a few selected energy indicators, show examples of results for hydropower, wind power and electricity from biomass, gas and coal. Lastly it will suggest methods to achieve results which are more consistent when comparing electricity production technologies. In general, methodological issues can affect the results of life cycle assessments. In this paper, the authors have focused on the effect of system boundaries for energy indicators and found that the internal ranking of cases within one electricity generation technology is dependent on the indicator used. These variations do not, however, alter the general ranking of the major technologies studied. The authors suggest that future assessments should focus on a smaller set of indicators: the Cumulative Energy Demand (CED), which is the most “universal” indicator, Energy Payback Ratio (EPR) for assessment of upstream activities, and a suggested “Cumulative Fossil Energy Demand” (CFED) for resource depletion assessments. There is also a need for stricter standardisation and increased transparency in the assessment of energy products. - Highlights: • There is a need for stricter standardisation of energy performance assessments. • System boundaries for renewable sources should be harmonised. • One should focus on a smaller set of indicators. CED should be included

    Full Text Available Serbian Environmental Protection Agency followed international and national indicators to do monitoring of forested landscape area for the period 1990-2000. Based on the data obtained by Corine Land Cover methodology following the indicators like Forest area, Forested landscape, Forest land and Forest and semi natural area, analysis was done. The forested landscape indicators analysis helped trends monitoring during the period from 1990 - 2000 year. Dynamic of forested area changes could have direct impact on the practical implementation of indicators. Indicator Forest area can be used in planning sustainable use of forests. Recorded growth rates value in 2000year, compared to the 1990th is 0.296%. Indicator Forested landscape increase for 0.186% till 2000 year, while the indicator Forested Land recorded value growth rate of 0.193%. Changes in rates of those indicators can be used in the future for “emission trading”. The smallest increment of rate change of 0.1% was recorded in indicator Forests and semi natural area. Information given by this indicator can be used for monitoring habitats in high mountain areas.

  14. SOCIAL INDICATORS FOR EVALUATING SUSTAINABILITY OF GOAT LIVESTOCK FARMS: METHODOLOGICAL APPROACH

    Directory of Open Access Journals (Sweden)

    Francisco de Asís Ruiz Morales

    2009-02-01

    Full Text Available Currently, sustainability is an objective for any economic activity or development process. Many studies with theoretical reflections relating to the concept of sustainability exist, but few methodological contributions adequately quantify and evaluate the level of sustainability of agraricultural systems, specifically with respect to small ruminant. The level of sustainability of these systems should be estimated taking into account not only economic and environmental aspects, but also social ones. Despite its importance to the functioning of agraricultural systems, the social dimension has been little addressed, and is frequently ignored in studies of this nature. Then, the objective of this study is to carry out methodological reflections based on identification and quantification of social indicators applied to goat livestock farms. Furthermore, this study forms part of a broader comparative study on sustainable development of animal systems in Andalusia (Spain and Chiapas (Mexico, in which economic, environmental, and social indicators are used in an integrated manner. The methodology used to obtain indicators is based on the authors´ knowledge of the functioning of goat livestock systems, focus groups and opinions of experts in the field, and revision of the available bibliography. As a result of the study, we propose a group of indicators made up of several variables based on the logical-mathematical principals of different scales of measurement as well as on multicriteria analysis. The social indicators proposed refer to several themes: i multi-functionality; ii membership in professional associations; iii implication for local life; iv social well-being (quality of life, especially that related to work; and v continuity of the goats livestock activity.

    An approach to derive relationships for defining land degradation and desertification risk and developing appropriate tools for assessing the effectiveness of the various land management practices using indicators is presented in the present paper. In order to investigate which indicators are most effective in assessing the level of desertification risk, a total of 70 candidate indicators was selected providing information for the biophysical environment, socio-economic conditions, and land management characteristics. The indicators were defined in 1,672 field sites located in 17 study areas in the Mediterranean region, Eastern Europe, Latin America, Africa, and Asia. Based on an existing geo-referenced database, classes were designated for each indicator and a sensitivity score to desertification was assigned to each class based on existing research. The obtained data were analyzed for the various processes of land degradation at farm level. The derived methodology was assessed using independent indicators, such as the measured soil erosion rate, and the organic matter content of the soil. Based on regression analyses, the collected indicator set can be reduced to a number of effective indicators ranging from 8 to 17 in the various processes of land degradation. Among the most important indicators identified as affecting land degradation and desertification risk were rain seasonality, slope gradient, plant cover, rate of land abandonment, land-use intensity, and the level of policy implementation.

  19. Laboratory methodologies for indicators of iron status: strengths, limitations, and analytical challenges.

    Pfeiffer, Christine M; Looker, Anne C

    2017-12-01

    Biochemical assessment of iron status relies on serum-based indicators, such as serum ferritin (SF), transferrin saturation, and soluble transferrin receptor (sTfR), as well as erythrocyte protoporphyrin. These indicators present challenges for clinical practice and national nutrition surveys, and often iron status interpretation is based on the combination of several indicators. The diagnosis of iron deficiency (ID) through SF concentration, the most commonly used indicator, is complicated by concomitant inflammation. sTfR concentration is an indicator of functional ID that is not an acute-phase reactant, but challenges in its interpretation arise because of the lack of assay standardization, common reference ranges, and common cutoffs. It is unclear which indicators are best suited to assess excess iron status. The value of hepcidin, non-transferrin-bound iron, and reticulocyte indexes is being explored in research settings. Serum-based indicators are generally measured on fully automated clinical analyzers available in most hospitals. Although international reference materials have been available for years, the standardization of immunoassays is complicated by the heterogeneity of antibodies used and the absence of physicochemical reference methods to establish "true" concentrations. From 1988 to 2006, the assessment of iron status in NHANES was based on the multi-indicator ferritin model. However, the model did not indicate the severity of ID and produced categorical estimates. More recently, iron status assessment in NHANES has used the total body iron stores (TBI) model, in which the log ratio of sTfR to SF is assessed. Together, sTfR and SF concentrations cover the full range of iron status. The TBI model better predicts the absence of bone marrow iron than SF concentration alone, and TBI can be analyzed as a continuous variable. Additional consideration of methodologies, interpretation of indicators, and analytic standardization is important for further

    This study aimed to develop a methodological tool to analyze and monitor the green jobs in the context of Occupational Health and Safety. A literature review in combination with an investigation of Occupational Health Indicators was performed. The resulting tool of Occupational Health Indicators was based on the existing information of "Single Report" and was validated by national's experts. The tool brings together 40 Occupational Health Indicators in four key fields established by World Health Organization in their conceptual framework "Health indicators of sustainable jobs." The tool proposed allows for assessing if the green jobs enabled to follow the principles and requirements of Occupational Health Indicators and if these jobs are as good for the environment as for the workers' health, so if they can be considered quality jobs. This shows that Occupational Health Indicators are indispensable for the assessment of the sustainability of green jobs and should be taken into account in the definition and evaluation of policies and strategies of the sustainable development.

    Full Text Available Two main components of the problem studied in the article are revealed. At the practical level, the provision of the convenient tools allowing a comprehensive evaluation the proposed innovative project in terms of its possibilities for inclusion in the portfolio or development program, and on the level of science – the need for improvement and complementing the existing methodology of assessment of innovative projects attractiveness in the context of their properties and a specific set of components. The research is scientifically applied since the problem solution involves the science-based development of a set of techniques, allowing the practical use of knowledge gained from large information arrays at the initialization stage. The purpose of the study is the formation of an integrated indicator of the project innovation, with a substantive justification of the calculation method, as a tool for the evaluation and selection of projects to be included in the portfolio of projects and programs. The theoretical and methodological basis of the research is the conceptual provisions and scientific developments of experts on project management issues, published in monographs, periodicals, materials of scientific and practical conferences on the topic of research. The tasks were solved using the general scientific and special methods, mathematical modelling methods based on the system approach. Results. A balanced system of parametric single indicators of innovation is presented – the risks, personnel, quality, innovation, resources, and performers, which allows getting a comprehensive idea of any project already in the initial stages. The choice of a risk tolerance as a key criterion of the “risks” element and the reference characteristics is substantiated, in relation to which it can be argued that the potential project holds promise. A tool for calculating the risk tolerance based on the use of matrices and vector analysis is proposed

    Full Text Available The aim of this work was to propose a methodology for quantifying the environmental compensation through the spatial analysis of vulnerability indicators. A case study was applied for the analysis of sand extraction enterprises, in the region of Descalvado and Analândia, inland of São Paulo State, Brazil. Environmental vulnerability scores were attributed for the indicators related to erosion, hydrological resources and biodiversity loss. This methodological proposal allowed analyzing the local alternatives of certain enterprise with the objective of reducing impacts and at the same time reducing the costs of environmental compensation. The application of the methodology significantly reduced the subjectivity degree usually associated to the most of the methodologies of impact evaluation.O termo compensação ambiental refere-se à obrigação do empreendedor em apoiar a implantação e manutenção de Unidades de Conservação, aplicável a empreendimentos de significativo impacto ambiental, de acordo com a Lei 9.986/2000. Esta lei estabelece que o volume de recursos a ser aplicado pelo empreendedor deve ser de no mínimo 0,5% dos custos totais previstos para a implantação do empreendimento, sendo que este percentual deve ser fixado pelo órgão ambiental competente, de acordo com o grau de impacto ambiental. Sendo assim, o presente artigo tem o objetivo de propor uma metodologia para quantificação da compensação ambiental através da análise espacial de indicadores de vulnerabilidade ambiental. A proposta foi aplicada através de um estudo de caso em empreendimentos de mineração de areia, na região de Descalvado/Analândia, interior do Estado de São Paulo. Índices de vulnerabilidade ambiental foram atribuídos a indicadores de impactos relacionados à erosão, recursos hídricos e perda de biodiversidade. Esta metodologia representa importante instrumento de planejamento ambiental e econômico, podendo ser adaptada a diversos

    Water productivity is an area of growing interest in assessing the impact of human economic activities on water resources, especially in arid regions. Indicators of water productivity can assist water users in evaluating sectoral water use efficiency, identifying sources of pressure on water resources, and in supporting water allocation rationale under scarcity conditions. This case study for the water-scarce Middle Rio Grande River Basin aims to develop an environmental-economic accounting approach for water use in arid river basins through a methodological framework that relates water use to human economic activities impacting regional water resources. Water uses are coupled to economic transactions, and the complex but mutual relations between various water using sectors estimated. A comparison is made between the calculated water productivity indicators and representative cost/price per unit volume of water for the main water use sectors. Although it contributes very little to regional economic output, preliminary results confirm that Irrigation is among the sectors with the largest direct water use intensities. High economic value and low water use intensity economic sectors in the study region include Manufacturing, Mining, and Steam Electric Power. Water accounting challenges revealed by the study include differences in water management regimes between jurisdictions, and little understanding of the impact of major economic activities on the interaction between surface and groundwater systems in this region. A more comprehensive assessment would require the incorporation of environmental and social sustainability indicators to the calculated water productivity indicators.

    Energy audits in wastewater treatment plants (WWTPs) reveal large differences in the energy consumption in the various stages, depending also on the indicators used in the audits. This work is aimed at formulating a suitable methodology to perform audits in WWTPs and identifying the most suitable key energy consumption indicators for comparison among different plants and benchmarking. Hydraulic-based stages, stages based on chemical oxygen demand, sludge-based stages and building stages were distinguished in WWTPs and analysed with different energy indicators. Detailed energy audits were carried out on five small WWTPs treating less than 10,000 population equivalent and using continuous data for 2 years. The plants have in common a low designed capacity utilization (52% on average) and equipment oversizing which leads to waste of energy in the absence of controls and inverters (a common situation in small plants). The study confirms that there are several opportunities for reducing energy consumption in small WWTPs: in addition to the pumping of influent wastewater and aeration, small plants demonstrate low energy efficiency in recirculation of settled sludge and in aerobic stabilization. Denitrification above 75% is ensured through intermittent aeration and without recirculation of mixed liquor. Automation in place of manual controls is mandatory in illumination and electrical heating.

    Full Text Available The stability of development and the results of activity of organizations representing noncommercial economic sector depend on a properly organized and effectively operated system of control about payments and funds, property, reporting and other items. To arrange the control function of management for nonbudget unprofitable organizations we single out four groups of control according to the feature of entity initiative, they are: state, public, donative, managerial. Each of them differs in its application form and sphere of interests. The article establishes common and distinct features of organizations of commercial and noncommercial economic sectors, which influence upon the organization and methodology of their control. The most significant for nonbudget unprofitable organizations are: the aim and direction of activity, the absence of production, the sources of financing, the ways of efficiency control. The paper substantiates the importance of indicative control for increasing the efficiency of the activity of nonbudget unprofitable organizations. It describes the main financial indicators of possible inefficiency for nonbudget unprofitable organization activity: debit and credit indebtedness; the mobility of own funds; a part of stocks in current assets; the rhythm of movement of funds; penalty sanctions on the part of controlling bodies; monetary circulation related to counteragents; the deviation of actual indices from planned (estimated; atypical operations for an organization; the concentration of the capital attracted; the specific gravity of administrative costs in the costs of operating activity.

    Highlights: • We spatially quantified and visualized the economic indicators of onshore wind energy in Sweden. • Possible land use constraints to wind energy were taken into account. • Economic indicators were estimated on the basis of two wind turbines. • We used a GIS-based methodology for this analysis and found it very useful. • Results suggest that Sweden holds economic feasible wind energy resource, specially in the southern and central regions. - Abstract: Due to modern advancements in renewable energy systems and increasing prices of fossil fuels wind energy is getting a lot of attention all over the world. In this regard, Sweden also fixed motivated targets to get energy supply from local renewable energy resources. So, local wind power could help the country in achieving the targets. In this study, economic indicators of wind energy were spatially estimated for Sweden by using ArcGIS tool. In order to do this, as input data one-year high resolution modeled annual average wind data was processed by means of Rayleigh distribution, wind turbine power curve, land use constraints, technical constraints and economic parameters. Based on the input data, it was concluded that Sweden possesses economically feasible wind energy resource. The results of the study indicate that southern and central regions could produce economically viable wind electricity in all aspects as compared to the northern region of the country. Lastly, it was recommended to speed up wind energy penetration in Sweden, communal awareness and acceptance regarding the resource should be increased to avoid possible misunderstanding. Additionally, the capability of the national electric grid should be enhanced to take up the large scale unpredictable wind energy resource.

    2014-01-01

    The Genuine Progress Indicator (GPI) has emerged as an important monetary measure of economic well-being. Unlike mainstream economic indicators, primarily Gross Domestic Product (GDP), the GPI accounts for both the benefits and costs of economic production across diverse economic, social, and environmental domains in a more comprehensive manner. Recently, the GPI has gained traction in subnational policy in the United States, with GPI studies being conducted in a number of states and with their formal adoption by several state governments. As the GPI is applied in different locations, new methods are developed, different data sources are available, and new issues of policy relevance are addressed using its component indicators. This has led to a divergence in methods, reducing comparability between studies and yielding results that are of varying methodological sophistication. In this study, we review the “state of the art” in recent US state-level GPI studies, focusing on those from Hawaii, Maryland, Ohio, Utah, and Vermont. Through adoption of a consistent approach, these and future GPI studies could utilize a framework that supports more uniform, comparable, and accurate measurements of progress. We also identify longer-term issues, particularly related to treatment of nonrenewable resource depletion, government spending, income inequality, and ecosystem services. As these issues are successfully addressed and disseminated, a “GPI 2.0” will emerge that better measures economic well-being and has greater accuracy and policy relevance than past GPI measurements. As the GPI expands further into mainstream policy analysis, a more formal process by which methods could be updated, standardized, and applied is needed.

    The scope of environmental impact statements prepared during the past few years has steadily expanded to incorporate all aspects of the social as well as the natural environment, including demographic, economic, social, political, and cultural conditions. Broadly conceived, social impacts are alterations in people's living conditions that occur in conjunction with a new policy, program, or project, and that (1) are in addition to all other concurrent changes produced by other factors, and (2) are seen by those affected as significant social events. Since any social environment is constantly changing, the crucial problems in analyzing social impacts are to identify those social alterations that are a direct or indirect result of the specific action under examination, apart from all other events and changes, and to determine which of these alterations are having significant social effects on the people involved. Three features of this conception of social impacts are especially noteworthy. First, although impacts are often thought of as undesirable or detrimental in nature, they may also be desirable or beneficial. Second, although impacts are often described as caused by prior intervening innovations, in reality they always interact with their original causes in a reciprocal process, either immediately or after some time lag. Third, the purpose of social impact assessment is to enable policy makers to anticipate and plan for potential impacts before they occur, and then act to prevent or mitigate undesired impacts. A new methodology for performing social impact assessment and management studies that meet current needs by emphasizing standardized social indicators and social planning techniques is proposed. We refer to our approach as the Social Impact and Planning (SIP) method of social impact assessment

    Full Text Available Purpose: The proposed methodology hopes to provide a systematic multi-disciplinary approach to assess the thermal environment while minimizing unneeded efforts. Design/methodology/approach: Different factors affect the perception of the human thermal experience: metabolic rate (biology, surrounding temperatures (heat balance and environmental factors and cognitive treatment (physiology.This paper proposes a combination of different multidisciplinary variables to generate a unique heat comfort assessment methodology. The variables at stake are physiological, biological, and environmental. Our own heat analysis is thoroughly presented and all relevant equations are described. Findings: Most companies are oblivious about potential dangers of heat stress accidents and thus about methods to monitor and prevent them. This methodology enables the company or the concerned individual to conduct a preliminary assessment with minimal wasted resources and time in unnecessary steps whilst providing a guideline for a detailed study with minimal error rates if needed. More so, thermal comfort is an integral part of sound ergonomics practices, which in turn are decisive for the success of any lean six sigma initiative. Research limitations/implications: This methodology requires several full implementations to finalize its design. Originality/value: Most used heat comfort models are inherently uncertain and tiresome to apply. An extensive literature review confirms the need for a uniform assessment methodology that combines the different thermal comfort models such as the Fanger comfort model (PMV, PPD and WGBT since high error rates coupled with tiresome calculations often hinder the thermal assessment process.

    This article provides the assessment of heavy metal soil pollution with using the calculation of various pollution indices and contains also summarization of the sources of heavy metal soil pollution. Twenty described indices of the assessment of soil pollution consist of two groups: single indices and total complex indices of pollution or contamination with relevant classes of pollution. This minireview provides also the classification of pollution indices in terms of the complex assessment of soil quality. In addition, based on the comparison of metal concentrations in soil-selected sites of the world and used indices of pollution or contamination in soils, the concentration of heavy metal in contaminated soils varied widely, and pollution indices confirmed the significant contribution of soil pollution from anthropogenic activities mainly in urban and industrial areas.

  17. Functional-diversity indices can be driven by methodological choices and species richness.

    Poos, Mark S; Walker, Steven C; Jackson, Donald A

    2009-02-01

    Functional diversity is an important concept in community ecology because it captures information on functional traits absent in measures of species diversity. One popular method of measuring functional diversity is the dendrogram-based method, FD. To calculate FD, a variety of methodological choices are required, and it has been debated about whether biological conclusions are sensitive to such choices. We studied the probability that conclusions regarding FD were sensitive, and that patterns in sensitivity were related to alpha and beta components of species richness. We developed a randomization procedure that iteratively calculated FD by assigning species into two assemblages and calculating the probability that the community with higher FD varied across methods. We found evidence of sensitivity in all five communities we examined, ranging from a probability of sensitivity of 0 (no sensitivity) to 0.976 (almost completely sensitive). Variations in these probabilities were driven by differences in alpha diversity between assemblages and not by beta diversity. Importantly, FD was most sensitive when it was most useful (i.e., when differences in alpha diversity were low). We demonstrate that trends in functional-diversity analyses can be largely driven by methodological choices or species richness, rather than functional trait information alone.

    The ODYSSEE database on energy efficiency indicators (www.odyssee-indicators.org) has been set up to enable the monitoring and evaluation of realised energy efficiency improvements and related energy savings. The database covers the 27 EU countries as well as Norway and Croatia. Energy indicators that relate energy consumption to a physical output (ton of steel), a performance (person-km driven per car) or the number of energy using devices (refrigerators) can show the increase in energy efficiency realised, and the amount of energy saved. By aggregating indicators, Odyssee calculates energy efficiency indices by sector and for the whole economy (so-called ODEX), in order to evaluate overall energy efficiency progress. This work contributes to the growing need for quantitative monitoring and evaluation of the impacts of energy policies and measures, both at the EU and national level, e.g. due to the Energy Service Directive. Because of the central role of Odyssee indicators in policy evaluations it becomes more important to know how reliable the Odyssee figures are, or in other words, what is the uncertainty margin for the indicator values and the related savings. This report presents a first analysis of uncertainty margins in the indicators and savings figures. The work builds on earlier work in the preceding Odyssee project with regard to the quality of input data used in Odyssee.

    There is a growing interest and major challenge to understand the way environmental variability and climatic change have affected and will affect ecosystems and populations. Long-term records of population parameters of vertebrates are rare, but invaluable to address this challenge. The network CLIMPOP brings together French researchers working with long term data collected on individually marked animals to study the effects of climate change on a range of vertebrate populations (reptiles, birds and mammals) and standardised methods to link climatic factors and demographic parameters. The funding from GICC-IFB has allowed the CLIMPOP group to hire a post doc bridging methodologists and ecologists, organize a workshop and support field studies. Several analyses on a series of vertebrates have been carried out on the link between large-scale and small-scale climatic factors and population dynamics. In addition the CLIMPOP group has carried out a major methodological paper reviewing statistical models and procedures to study the influence of climate on vital rates based on the analysis of individual monitoring data, to identify potential pitfalls in the utilization of these models and procedures, to review published papers in which the influence of climatic variation on survival probability in vertebrate populations has been addressed, to evaluate whether the results from these studies are relevant and to draw practical recommendations to efficiently address effects of climate effects on vital rates in natural vertebrate populations. This evaluation raised six potential methodological issues and indicates that so far most of the studies found in the ecological literature can be considered as being useful for the purpose of generating hypothesis rather than for that of obtaining solid evidence for the impact of climatic factors on vital rates.

    Citizen science is having increasing influence on environmental monitoring as its advantages are becoming recognised. However methodologies are often simplified to make them accessible to citizen scientists. We tested whether a recent citizen science survey (the OPAL Air Survey) could detect trends in lichen community composition over transects away from roads. We hypothesised that the abundance of nitrophilic lichens would decrease with distance from the road, while that of nitrophobic lichens would increase. The hypothesised changes were detected along strong pollution gradients, but not where the road source was relatively weak, or background pollution relatively high. We conclude that the simplified OPAL methodology can detect large contrasts in nitrogenous pollution, but it may not be able to detect more subtle changes in pollution exposure. Similar studies are needed in conjunction with the ever-growing body of citizen science work to ensure that the limitations of these methods are fully understood. -- Highlights: •We investigated the validity of a simplified citizen science methodology. •Lichen abundance data were used to indicate nitrogenous air pollution. •Significant changes were detected beside busy roads with low background pollution. •The methodology detected major, but not subtle, contrasts in pollution. •Sensitivity of citizen science methods to environmental change must be evaluated. -- A simplified lichen biomonitoring method used for citizen science can detect the impact of nitrogenous air pollution from local roads

    Full Text Available Glucolipotoxicity is a major pathophysiological mechanism in the development of insulin resistance and type 2 diabetes mellitus (T2D. We aimed to detect subtle changes in the circulating lipid profile by shotgun lipidomics analyses and to associate them with four different insulin sensitivity indices.The cross-sectional study comprised 90 men with a broad range of insulin sensitivity including normal glucose tolerance (NGT, n = 33, impaired glucose tolerance (IGT, n = 32 and newly detected T2D (n = 25. Prior to oral glucose challenge plasma was obtained and quantitatively analyzed for 198 lipid molecular species from 13 different lipid classes including triacylglycerls (TAGs, phosphatidylcholine plasmalogen/ether (PC O-s, sphingomyelins (SMs, and lysophosphatidylcholines (LPCs. To identify a lipidomic signature of individual insulin sensitivity we applied three data mining approaches, namely least absolute shrinkage and selection operator (LASSO, Support Vector Regression (SVR and Random Forests (RF for the following insulin sensitivity indices: homeostasis model of insulin resistance (HOMA-IR, glucose insulin sensitivity index (GSI, insulin sensitivity index (ISI, and disposition index (DI. The LASSO procedure offers a high prediction accuracy and and an easier interpretability than SVR and RF.After LASSO selection, the plasma lipidome explained 3% (DI to maximal 53% (HOMA-IR variability of the sensitivity indexes. Among the lipid species with the highest positive LASSO regression coefficient were TAG 54:2 (HOMA-IR, PC O- 32:0 (GSI, and SM 40:3:1 (ISI. The highest negative regression coefficient was obtained for LPC 22:5 (HOMA-IR, TAG 51:1 (GSI, and TAG 58:6 (ISI.Although a substantial part of lipid molecular species showed a significant correlation with insulin sensitivity indices we were able to identify a limited number of lipid metabolites of particular importance based on the LASSO approach. These few selected lipids with the closest

    Full Text Available Dry fecal matter production was estimated from neutral detergent indicators on indigestible fiber, indigestible acid detergent fiber, indigestible dry matter, incubated for 144 hours and 288 hours, as well as chromium oxide (Cr2O3 and enriched and purified isolated lignin (LIPE® in two sampling schemes (3 and 5 days on buffaloes. Sample consisted of five castrated animals with average weight of 300 ± 0.6 kg fed on elephant grass cv Cameroon (Pennisetum purpureum. Experimental design consisted of randomized blocks in subdivided plots. Production of dry fecal matter was overestimated when using Cr2O3, indigestible acid detergent fiber 144 hours, indigestible neutral detergent fiber 144 hours, indigestible neutral detergent fiber 288 hours and indigestible dry matter 144 hours, while indigestible acid detergent fiber 288 hours, indigestible dry matter 288 hours and LIPE® did not differ from total collection. The same result was observed for apparent digestibility of nutrients. There was no difference in dry fecal matter production and digestibility between both collection periods of 3 and 5 days, demonstrating that a collection period of three days can be used to estimate dry fecal matter production in buffaloes. A three-day period of sample collection, in order to estimate dry fecal matter production and apparent digestibility coefficients, is therefore recommended. The use of LIPE®, fibers in indigestible acid detergent and indigestible dry matter as indicators, both latter incubated for 288 hours, result in accurate estimates of dry fecal matter production in confined buffaloes, fed on a forage based diet.

  9. A methodology approach for analysis of sustainability indicators as a tool for decision making using fuzzy logic

    2015-01-01

    The greatest challenge of this century is focused on sustainability, due to world population growth and consequently to the increased demand for resources such as water, food and energy. The main difficulty when discussing the issue of sustainable development is the evaluation methodology. Because of this, there is a need for a measurement tool that addresses these resources in a holistic manner and be able to translate data into results that can be interpreted. There are tools validated for this purpose like, 'Dashboard of Sustainability' and other developing like the CLEW Nexus by the International Atomic Energy Agency - IAEA. This study aims to develop a new model to analyze the correlation between variables, energy, water, land use and climate, using Artificial Intelligence through Fuzzy Logic, having as a data source, indicators that represent one or more resource, considering the relative and temporal distribution required to research results and behaviors. The result is a final index generated by mapping these input data. The results presented using this methodology are indicators of Brazil, but can be applied to any other country, allowing a comparison analysis of the behavior of indices between regions. The contribution of this project will be the availability of a tool with powerful computational resource, aimed at decision makers to assist in developing strategies and development policies.

    This study sought to develop methodology for the construction of a Panel for the Monitoring and Evaluation of Management of the Unified Health System (SUS). The participative process used in addition to the systematization conducted made it possible to identify an effective strategy for building management tools in partnership with researchers, academic institutions and managers of the SUS. The final systematization of the Panel selected indicators for the management of the SUS in terms of Demand, Inputs, Processes, Outputs and Outcomes in order to provide a simple, versatile and useful tool for evaluation at any level of management and more transparent and easier communication with all stakeholders in decision-making. Taking the management of the SUS as the scope of these processes and practices in all normative aspects enabled dialog between systemic theories and those which consider the centrality of the social actor in the decision-making process.

  16. Assessing the Ability of Vegetation Indices to Identify Shallow Subsurface Water Flow Pathways from Hyperspectral Imagery Using Machine Learning: Methodology

    Byers, J. M.; Doctor, K.

    2017-12-01

    A common application of the satellite and airborne acquired hyperspectral imagery in the visible and NIR spectrum is the assessment of vegetation. Various absorption features of plants related to both water and chlorophyll content can be used to measure the vigor and access to underlying water sources of the vegetation. The typical strategy is to form hand-crafted features from the hyperspectral data cube by selecting two wavelengths to form difference or ratio images in the pixel space. The new image attempts to provide greater contrast for some feature of the vegetation. The Normalized Difference Vegetation Index (NDVI) is a widely used example formed from the ratio of differences and sums at two different wavelengths. There are dozens of these indices that are ostensibly formed using insights about the underlying physics of the spectral absorption with claims to efficacy in representing various properties of vegetation. In the language of machine learning these vegetation indices are features that can be used as a useful data representation within an algorithm. In this work we use a powerful approach from machine learning, probabilistic graphical models (PGM), to balance the competing needs of using existing hydrological classifications of terrain while finding statistically reliable features within hyperspectral data for identifying the generative process of the data. The algorithm in its simplest form is called a Naïve Bayes (NB) classifier and can be constructed in a data-driven estimation procedure of the conditional probability distributions that form the PGM. The Naïve Bayes model assumes that all vegetation indices (VI) are independent of one another given the hydrological class label. We seek to test its validity in a pilot study of detecting subsurface water flow pathways from VI. A more sophisticated PGM will also be explored called a tree-augmented NB that accounts for the probabilistic dependence between VI features. This methodology provides a

    2009-01-01

    A bottom-up methodological framework was developed and applied for the period 1985-2002, to selected manufacturing sub-sectors in Greece namely, food, beverages and tobacco, iron and steel, non-ferrous metals, non-metallic minerals and paper. Disaggregate physical data were aggregated according to their specific energy consumption (SEC) values and physical energy efficiency indicators were estimated. The Logarithmic Mean Divisia index method was also used and the effects of the production, structure and energy efficiency to changes in sub-sectoral manufacturing energy use were further assessed. Primary physical energy efficiency improved by 28% for the iron and steel and by 9% for the non-metallic minerals industries, compared to the base year 1990. For the food, beverages and tobacco and the paper sub-sectors, primary efficiency deteriorated by 20% and by 15%, respectively; finally electricity efficiency deteriorated by 7% for the non-ferrous metals. Sub-sectoral energy use is mainly driven by production output and energy efficiency changes. Sensitivity analysis showed that alternative SEC values do not influence the results whereas the selected base year is more critical for this analysis. Significant efficiency improvements refer to 'heavy' industry; 'light' industry needs further attention by energy policy to modernize its production plants and improve its efficiency

  6. Vers une éthique climatique plus efficace : motivations et incitations

    Directory of Open Access Journals (Sweden)

    Michel Bourban

    2014-06-01

    Full Text Available Cet article vise à justifier, puis à appliquer une éthique climatique centrée sur les intérêts des acteurs économiques. Après avoir expliqué pourquoi le changement climatique pose un problème important de motivation, je montre pour quelles raisons les incitations peuvent au moins partiellement y remédier. Je développe ensuite deux possibilités d’institutionnalisation de l’éthique des incitations. La première consiste en une taxe internationale augmentant progressivement le coût des émissions de dioxyde de carbone, un dispositif auquel il convient d’ajouter des subsides pour la recherche, le développement et le déploiement des énergies renouvelables. La seconde consiste en un marché global du carbone qui vise également à décourager l’utilisation des combustibles fossiles et à encourager l’utilisation de sources alternatives d’énergie. L’objectif est de montrer qu’une éthique climatique prenant en compte le problème de la motivation est plus efficace qu’une position qui se limite aux devoirs moraux incombant aux consommateurs et producteurs, soit de réduire leurs émissions.

  11. Methodology for comparative assessment of various electricity generation systems using health and environmental impacts as the indicators

    International Nuclear Information System (INIS)

    Takahara, Shogo; Homma, Toshimitsu; Matsuki, Yoshio; Muramatsu, Ken

    2010-12-01

    This report describes the procedure of the comparative risk assessment, which is the standard approach to compare health and environmental impacts of different electricity generation systems, together with the results of the assessments and the international consensus. While there are several approaches to compare the impacts, the Impact Pathway (Damage Function) Approach is known as a popular method. This approach is characterized as the methodology that considers the emissions from power plants and the other sources, the dispersions of those pollutants, and then the impacts to the recipients of the pollutants; while, the scope of the assessments, such as types of the fuel chains as well as the time and the space of the impacts, needs to be defined upon the purpose, and the data and the model need to be justified through the process of the assessment. This approach was examined at the Coordinated Research Programme (hereinafter, 'CRP), which the International Atomic Energy Agency (hereinafter, 'IAEA) implemented with the research institutes of 12 countries on the comparative risk assessment. Upon the results of the assessments made by the CRP of the IAEA and the ExternE of the European Commission (hereinafter 'EC'), it is concluded that the impacts of the fossil fuel (coal, oil and natural gas) chains are relatively larger than of the other fuel chains, especially when the secondary chemical transformation of the pollutants and the effects of global warming are considered. On the contrary, the impacts of nuclear fuel cycle are smaller than of the fossil fuel chains'; although, there are still needs for further consensus building on the risks of the severe accidents and on the impacts of long-lived radio-nuclides spreading on the global level.

    We discuss the methodological aspects related to the evaluation of turn-over and up-down sizing as indicators of work-related stress, in complex organizations like a university hospital. To estimate the active workers population we developed an algorithm which integrated several administrative databases. The indicators were standardized to take into account some potential confounders (age, sex, work seniority) when considering different hospital structures and job mansions. Main advantages of our method include flexibility in the choice of the analysis detail (hospital units, job mansions, a combination of both) and the possibility to describe over-time trends to measure the success of preventive strategies.

    To describe: a) the methods used to quantify biochemical indicators of Type 2 Diabetes (T2D), and other cardiovascular risk indicators in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) and b) compare the sub-sample with the non-selected participants in diverse socio-demographic, anthropometric and health characteristics. A sub-sample of 6 021 fasting adult participants was randomly selected from the total fasting participants (n=39 425). We compared diverse socio-demographic, anthropometric and health parameters between this sub-sample and the rest of the participants. No differences were found in sociodemographics characteristics, except age, between the sub-sample and from the rest of the fasting adults. In addition no difference were found between prevalences of overweight and obesity, central obesity, and previously diagnosed high blood pressure, T2D or hypertrigliceridemia. The randomly selected sub-sample was not essentially different from the rest of the fasting subjects. Thus, no bias is expected in the interpretation of cardiovascular risk indicators derived from these data.

    2014-01-01

    The Colombian National Federation of Coffee Growers (FNC) conducted an agro-ecological zoning study based on climate, soil, and terrain of the Colombian coffee-growing regions (CCGR) located in the tropics, between 1° and 11.5° N, in areas of complex topography. To support this study, a climate baseline was constructed at a spatial resolution of 5 km. Twenty-one bioclimatic indicators were drawn from this baseline data and from yield data for different coffee genotypes evaluated under conditions at eight experimental stations (ESs) belonging to the National Center for Coffee Research (CENICAFÉ). Three topographic indicators were obtained from a digital elevation model (DEM). Zoning at a national level resulted in the differentiation of 12 agro-climatic zones. Altitude notably influenced zone differentiation, however other factors such as large air currents, low-pressure atmospheric systems, valleys of the great rivers, and physiography also played an important role. The strategy of zoning according to coffee-growing conditions will enable areas with the greatest potential for the development of coffee cultivation to be identified, criteria for future research to be generated, and the level of technology implementation to be assessed.

    The purpose of this research is to establish urban indicators that can support a diagnosis through the application of CDU (scheme of urban inequalities) in the city of Medellin, Colombia, which has a population of about 1,850 inhabitants. Six (6) different quarters, representing all three (3) different social and economic levels, have been chosen in order to analyze and detect three (3) processes of legal and illegal ground occupation, their predominant use and their compatibility in urban accumulation with their associated production of habitation the first process is characterized by an illegal ground occupation with production of non legal habitation and invasion. The second process, the legal ground occupation with housing developed by the formal market, is associated to the private and official sectors. The third and last process, which occurred during the 80's, is characterized by illegal ground occupation and habitation production in steep areas of the city

    Full Text Available Sustainable access to safe drinking water protects against infectious disease and promotes overall health. Despite considerable progress toward increasing water access, safe water quality and reliable service delivery remain a challenge. Traditional financing strategies pay implementers based on inputs and activities, with minimal incentives for water quality monitoring and sustained service operation. Pay-for-performance offers an alternative financing strategy that delivers all or a portion of payment based on performance indicators of desired outputs or outcomes. A pay-for-performance approach in the water sector could quantify and incentivize health impact. Averted disability-adjusted life years (ADALYs have been used as a performance indicator to measure the burden of disease averted due to environmental health interventions. Water-related disease burden can be measured for application as an ADALYs performance indicator following either comparative risk assessment or quantitative microbial risk assessment. Comparative risk assessment models disease burden using water source type as a proxy indicator of microbial water quality, while quantitative microbial risk assessment models disease burden using concentrations of indicator pathogens. This paper compares these risk assessment methodologies, and summarizes the limitations of applying these approaches toward quantifying ADALYs as a performance indicator for water quality interventions.

  20. Developpement D'un Modele Climatique Regional: Fizr Simulation des Conditions de Janvier de la Cote Ouest Nord Americaine

    1995-11-01

    Le sujet de cette these concerne la modelisation numerique du climat regional. L'objectif principal de l'exercice est de developper un modele climatique regional ayant les capacites de simuler des phenomenes de meso-echelle spatiale. Notre domaine d'etude se situe sur la Cote Ouest nord americaine. Ce dernier a retenu notre attention a cause de la complexite du relief et de son controle sur le climat. Les raisons qui motivent cette etude sont multiples: d'une part, nous ne pouvons pas augmenter, en pratique, la faible resolution spatiale des modeles de la circulation generale de l'atmosphere (MCG) sans augmenter a outrance les couts d'integration et, d'autre part, la gestion de l'environnement exige de plus en plus de donnees climatiques regionales determinees avec une meilleure resolution spatiale. Jusqu'alors, les MCG constituaient les modeles les plus estimes pour leurs aptitudes a simuler le climat ainsi que les changements climatiques mondiaux. Toutefois, les phenomenes climatiques de fine echelle echappent encore aux MCG a cause de leur faible resolution spatiale. De plus, les repercussions socio-economiques des modifications possibles des climats sont etroitement liees a des phenomenes imperceptibles par les MCG actuels. Afin de circonvenir certains problemes inherents a la resolution, une approche pratique vise a prendre un domaine spatial limite d'un MCG et a y imbriquer un autre modele numerique possedant, lui, un maillage de haute resolution spatiale. Ce processus d'imbrication implique alors une nouvelle simulation numerique. Cette "retro-simulation" est guidee dans le domaine restreint a partir de pieces d'informations fournies par le MCG et forcee par des mecanismes pris en charge uniquement par le modele imbrique. Ainsi, afin de raffiner la precision spatiale des previsions climatiques de grande echelle, nous developpons ici un modele numerique appele FIZR, permettant d'obtenir de l'information climatique regionale valide a la fine echelle spatiale

    The oil exporting countries can be vulnerable to this row-material as the oil importing ones, due to their social economic dependence of the revenues generated by the oil and gas sector. So, it is also important for those countries the analysis of their social economic vulnerability in order to contribute for the comprehension of their real actions related to their production strategies, aiming to affect oil price and market-share. Due to that, this thesis proposes a methodology based on social economic indicators of oil exporting countries, which will enclose the following aspects: physical, productive, commercial, macro economic, fiscal and social. These indicators will be applied to the OPEC members, Norway and Mexico, and orientated through a normalized scale as in a multicriteria methodology (AHP - Analytic Hierarchy Process). The analyzed results will drive the social economic implications, and the studied countries will be classified in a scale that goes from very favorable to very unfavorable. The results point the main social economic fragilities of the oil exporting countries, designing pathways to Brazil and their possible exporting ambitions. The most important considerations that became from the vulnerable oil export countries experiences refers to the necessity to straight and increases their macro economic foundations, industrial diversification incentives and the creation of an stabilization fund (based on oil revenues) for the future generations, or to severe oil prices oscillations periods in the international market (author)

    Full Text Available Cette étude évalue la vulnérabilité de l’agriculture dans la plaine de Jeffera sud-est tunisien aux changements climatiques en utilisant la méthode Ricardienne. Cette méthode consiste à exprimer les revenus nets agricoles en fonction des variables climatiques, édaphiques et socio-économiques. Ces modèles ricardiens ont été testés sur la base des données d’une enquête réalisée dans le cadre de projet de développement dans la plaine Jeffera pour la compagne agricole 2002-2003.  Ces modèles ont permis d’exprimer d’une part la relation qui existe entre le revenu agricole et les variables climatiques (température et précipitation et d’autre part, d’analyser la sensibilité des revenus agricoles par rapport à ces variables climatiques. Des simulations ont été faites sur la base de scenario A2 résultat de la projection faite par le modèle HadCM3 à l’échelle nationale et régionale de la Tunisie.Les résultats de l’étude ont montré que la relation entre le revenu agricole et le climat est non linéaire. De même, les effets négatifs de certaines options d’adaptation ont montré que  l’agriculture dans la plaine de Jeffera est une agriculture paysanne basée sur le travail familial qui nécessite aujourd’hui un capital financier important et une marge de modernisation afin d’améliorer l’activité agricole dans les années futures. Tandis que les effets positifs de certaines autres options peuvent être servir comme des points de réflexion dans l’élaboration des stratégies d’adaptation aux changements climatiques comme l’utilisation des nouvelles technologies d’irrigation et l’intégration de l’activité de l’élevage dans l’exploitation agricole.

    Miguel, V.; Catalayud, A.; Ferrer, C.

    2007-01-01

    In this work a methodology to investigate deep drawing quality steel sheets deformation tendency under multiaxial deep drawing stresses has been proposed. the method consists in assaying a sheet in a wedge die in order to order to introduce a pure shear estate in the material 0 degree centigree, 45 degree centigree and 90 degree centigree rolling directions are selected in the assays, and transversal strain is the variable considered in them. a strain coefficient 0/% has been defined in order to evaluate thickness variations in the test. almost no changes in thickness have been registered and this indicates that strain carried out in the test is similar to that taking place in deep drawing. The stress necessary for practice a certain plastic deformation is obtained too and a potential function between them is formulated. Indicators presented in this work are compared to anisotropy and strength coefficients obtained in normalized tensile tests. these results allow us to justify the steel behaviour in the cup deep drawing processes related to ear forming.

    Given that floods continue to cause yearly significant worldwide human and material damages, flood risk mitigation is a key issue and a permanent challenge in developing policies and strategies at various spatial scales. Therefore, a basic phase is elaborating hazard and flood risk maps, documents which are an essential support for flood risk management. The aim of this paper is to develop an approach that allows for the identification of flash-flood and flood-prone susceptible areas based on computing and mapping of two indices: FFPI (Flash-Flood Potential Index) and FPI (Flooding Potential Index). These indices are obtained by integrating in a GIS environment several geographical variables which control runoff (in the case of the FFPI) and favour flooding (in the case of the FPI). The methodology was applied in the upper (mountainous) and middle (hilly) catchment of the Prahova River, a densely populated and socioeconomically well-developed area which has been affected repeatedly by water-related hazards over the past decades. The resulting maps showing the spatialization of the FFPI and FPI allow for the identification of areas with high susceptibility to flashfloods and flooding. This approach can provide useful mapped information, especially for areas (generally large) where there are no flood/hazard risk maps. Moreover, the FFPI and FPI maps can constitute a preliminary step for flood risk and vulnerability assessment.

    The quality of systematic reviews and meta-analyses on psoriasis, a chronic inflammatory skin disease that severely impairs quality of life and is associated with high costs, remains unknown. To assess the methodological quality of systematic reviews published on psoriasis. After a comprehensive search in MEDLINE, Embase and the Cochrane Database (PROSPERO: CDR42016041611), the quality of studies was assessed by two raters using the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Article metadata and journal-related bibliometric indices were also obtained. Systematic reviews were classified as low (0-4), moderate (5-8) or high (9-11) quality. A prediction model for methodological quality was fitted using principal component and multivariate ordinal logistic regression analyses. We classified 220 studies as high (17·2%), moderate (55·0%) or low (27·8%) quality. Lower compliance rates were found for AMSTAR question (Q)5 (list of studies provided, 11·4%), Q10 (publication bias assessed, 27·7%), Q4 (status of publication included, 39·5%) and Q1 (a priori design provided, 40·9%). Factors such as meta-analysis inclusion [odds ratio (OR) 6·22; 95% confidence interval (CI) 2·78-14·86], funding by academic institutions (OR 2·90, 95% CI 1·11-7·89), Article Influence score (OR 2·14, 95% CI 1·05-6·67), 5-year impact factor (OR 1·34, 95% CI 1·02-1·40) and article page count (OR 1·08, 95% CI 1·02-1·15) significantly predicted higher quality. A high number of authors with a conflict of interest (OR 0·90, 95% CI 0·82-0·99) was significantly associated with lower quality. The methodological quality of systematic reviews published about psoriasis remains suboptimal. The type of funding sources and author conflicts may compromise study quality, increasing the risk of bias. © 2017 British Association of Dermatologists.

Les gaz à effet de serre ne sont toutefois pas les seuls facteurs de modification du climat. Le rôle des aérosols doit aussi être souligné : il est admis que ces derniers ont partiellement masqué le pouvoir réchauffant des gaz à effet de serre depuis le début de l’ère industrielle. Ils interagissent en outre fortement avec le cycle de l’eau et un certain nombre de cycles biogéochimiques. C’est l’ensemble de ces interactions – entre aérosols, rayonnement, cycle hydrologique, etc. – que ce livre propose de passer en revue.

    Full Text Available Currently, agriculture is one of the most discussed topics in the theoretical field of sustainability. Debates regarding this issue are increasingly recurrent and put in question the model adopted from the post-war, the so-called green revolution. In the state of Rio Grande do Norte, the agricultural potential lies mainly in irrigated horticulture, where stands the agropolo Acu-Mossoró as one of the greatest watermelon producing regions of Brazil. The cultivation of watermelon, once dominated by large agricultural companies, is currently developed by agroecosystems whose management is characterized by family participation, including small farmers of rural settlements created by Incra. Aiming to assess the sustainability of this type of cultivation, was used the MESMIS methodology in the in São Romão settlement in Mossoró-RN, which is primarily engaged in the cultivation of irrigated melon. Seven critical points were determined and selected twenty-three indicators that directly affect the sustainability of the researched area.

    The implementation of an Internet option in an existing public health interview survey using a mixed-mode design is attractive because of lower costs and faster data availability. Additionally, mixed-mode surveys can increase response rates and improve sample composition. However, mixed-mode designs can increase the risk of measurement error (mode effects). This study aimed to determine whether the prevalence rates or mean values of self- and parent-reported health indicators for children and adolescents aged 0-17 years differ between self-administered paper-based questionnaires (SAQ-paper) and self-administered Web-based questionnaires (SAQ-Web), as well as between a single-mode control group and different mixed-mode groups. Data were collected for a methodological pilot of the third wave of the "German Health Interview and Examination Survey for Children and Adolescents". Questionnaires were completed by parents or adolescents. A population-based sample of 11,140 children and adolescents aged 0-17 years was randomly allocated to 4 survey designs-a single-mode control group with paper-and-pencil questionnaires only (n=970 parents, n=343 adolescents)-and 3 mixed-mode designs, all of which offered Web-based questionnaire options. In the concurrent mixed-mode design, both questionnaires were offered at the same time (n=946 parents, n=290 adolescents); in the sequential mixed-mode design, the SAQ-Web was sent first, followed by the paper questionnaire along with a reminder (n=854 parents, n=269 adolescents); and in the preselect mixed-mode design, both options were offered and the respondents were asked to request the desired type of questionnaire (n=698 parents, n=292 adolescents). In total, 3468 questionnaires of parents of children aged 0-17 years (SAQ-Web: n=708; SAQ-paper: n=2760) and 1194 questionnaires of adolescents aged 11-17 years (SAQ-Web: n=299; SAQ-paper: n=895) were analyzed.

  1. Safety functions and safety function indicators - key elements in SKB'S methodology for assessing long-term safety of a KBS-3 repository

    International Nuclear Information System (INIS)

    Hedin, A.

    2008-01-01

    The application of so called safety function indicators in SKB safety assessment of a KBS-3 repository for spent nuclear fuel is presented. Isolation and retardation are the two main safety functions of the KBS-3 concept. In order to quantitatively evaluate safety on a sub-system level, these functions need to be differentiated, associated with quantitative measures and, where possible, with quantitative criteria relating to the fulfillment of the safety functions. A safety function is defined as a role through which a repository component contributes to safety. A safety function indicator is a measurable or calculable property of a repository component that allows quantitative evaluation of a safety function. A safety function indicator criterion is a quantitative limit such that if the criterion is fulfilled, the corresponding safety function is upheld. The safety functions and their associated indicators and criteria developed for the KBS-3 repository are primarily related to the isolating potential and to physical states of the canister and the clay buffer surrounding the canister. They are thus not directly related to release rates of radionuclides. The paper also describes how the concepts introduced i) aid in focussing the assessment on critical, safety related issues, ii) provide a framework for the accounting of safety throughout the different time frames of the assessment and iii) provide key information in the selection of scenarios for the safety assessment.

    Porphyry-epithermal and orogenic gold are two of the most important styles of gold-bearing mineralization within orogenic belts. Populations of detrital gold resulting from bulk erosion of such regions may exhibit a compositional continuum wherein Ag, Cu, and Hg in the gold alloy may vary across the full range exhibited by natural gold. This paper describes a new methodology whereby orogenic and porphyry-epithermal gold may be distinguished according to the mineralogy of microscopic inclusions observed within detrital gold particles. A total of 1459 gold grains from hypogene, eluvial, and placer environments around calc-alkaline porphyry deposits in Yukon (Nucleus-Revenue, Casino, Sonora Gulch, and Cyprus-Klaza) have been characterized in terms of their alloy compositions (Au, Ag, Cu, and Hg) and their inclusion mineralogy. Despite differences in the evolution of the different magmatic hydrothermal systems, the gold exhibits a clear Bi-Pb-Te-S mineralogy in the inclusion suite, a signature which is either extremely weak or (most commonly) absent in both Yukon orogenic gold and gold from orogenic settings worldwide. Generic systematic compositional changes in ore mineralogy previously identified across the porphyry-epithermal transition have been identified in the corresponding inclusion suites observed in samples from Yukon. However, the Bi-Te association repeatedly observed in gold from the porphyry mineralization persists into the epithermal environment. Ranges of P-T-X conditions are replicated in the geological environments which define generic styles of mineralization. These parameters influence both gold alloy composition and ore mineralogy, of which inclusion suites are a manifestation. Consequently, we propose that this methodology approach can underpin a widely applicable indicator methodology based on detrital gold.

    Les activites humaines energivores telles l'utilisation intensive de l'automobile, la surconsommation de biens et l'usage excessif d'electricite contribuent aux changements climatiques et autres problemes environnementaux. Bien que plusieurs recherches rapportent que l'etre humain est de plus en plus conscient de ses impacts sur le climat de la planete, ces memes recherches indiquent qu'en general, les gens continuent a se comporter de facon non ecologique. Que ce soit a l'ecole ou dans la communaute, plusieurs chercheurs en education relative a l'environnement estiment qu'une personne bien intentionnee est capable d'adopter des comportements plus respectueux de l'environnement. Le but de cette these etait de comprendre le processus d'integration de comportements d'attenuation des changements climatiques dans des familles. A cette fin, nous nous sommes fixe deux objectifs : 1) decrire les competences et les procedes qui favorisent l'adoption de comportements d'attenuation des changements climatiques dans des familles et 2) decrire les facteurs et les dynamiques familiales qui facilitent et limitent l'adoption de comportements d'attenuation des changements climatiques dans des familles. Des familles ont ete invitees a essayer des comportements personnels et collectifs d'attenuation des changements climatiques de sorte a integrer des modes de vie plus ecologiques. Sur une periode de huit mois, nous avons suivi leur experience de changement afin de mieux comprendre comment se produit le processus de changement dans des familles qui decident volontairement d'adopter des comportements d'attenuation des changements climatiques. Apres leur avoir fourni quelques connaissances de base sur les changements climatiques, nous avons observe le vecu de changement des familles durant huit mois d'essais a l'aide de journaux reflexifs, d'entretiens d'explicitation et du journal du chercheur.

In Morocco, we should think of desalinization with renewable energies (solar, wind and the use of this water mainly in coastal areas where climate, land quality, sun and wind are adequate to these projects. To anticipate the future of food security of the country, attention should be given to the use of readily available resources to overcome the structural deficit in wheat starch and animal protein. The study suggests the use of other starch sources that Morocco can produce easily such as potato. For animal protein, we suggest fisheries resources which are still underused by the population. Résumé On présente une étude prospective concernant l’impact probable des changements climatiques sur les systèmes de culture et d’élevage au Maroc. D’après le constat de terrain et dans les limites de ce que signifie ce genre d’étude, l’effet direct du réchauffement climatique peut conduire à terme (et c’est déjà le cas dans certaines contrées à la nécessité d’une redistribution variétale pour des espèces exigeantes en froid comme les rosacées.

Le réchauffement climatique peut aussi obliger à faire évoluer les systèmes d’élevage et de culture en faisant déplacer la frontière de la sécheresse un peu plus vers le centre et le nord du pays; l’aride serait peut-être envahi par la désertification, le semi-aride passerait en partie à l’étage aride et le Bour dit favorable en partie dans le semi-aride.

    The National Quality Forum previously approved a quality indicator for mortality after congenital heart surgery developed by the Agency for Healthcare Research and Quality (AHRQ). Several parameters of the validated Risk Adjustment for Congenital Heart Surgery (RACHS-1) method were included, but others differed. As part of the National Quality Forum endorsement maintenance process, developers were asked to harmonize the 2 methodologies. Parameters that were identical between the 2 methods were retained. AHRQ's Healthcare Cost and Utilization Project State Inpatient Databases (SID) 2008 were used to select optimal parameters where differences existed, with a goal to maximize model performance and face validity. Inclusion criteria were not changed and included all discharges for patients model includes procedure risk group, age (0-28 days, 29-90 days, 91-364 days, 1-17 years), low birth weight (500-2499 g), other congenital anomalies (Clinical Classifications Software 217, except for 758.xx), multiple procedures, and transfer-in status. Among 17 945 eligible cases in the SID 2008, the c statistic for model performance was 0.82. In the SID 2013 validation data set, the c statistic was 0.82. Risk-adjusted mortality rates by center ranged from 0.9% to 4.1% (5th-95th percentile). Congenital heart surgery programs can now obtain national benchmarking reports by applying AHRQ Quality Indicator software to hospital administrative data, based on the harmonized RACHS-1 method, with high discrimination and face validity. © 2016 The Authors.

    Principale source d'approvisionnement en eau potable de la municipalite d'Edmundston, le bassin versant Iroquois/Blanchette est un enjeu capital pour cette derniere, d'ou les efforts constants deployes pour assurer la preservation de la qualite de son eau. A cet effet, plusieurs etudes y ont ete menees. Les plus recentes ont identifie des menaces de pollution de diverses origines dont celles associees aux changements climatiques (e.g. Maaref 2012). Au regard des impacts des modifications climatiques annonces a l'echelle du Nouveau-Brunswick, le bassin versant Iroquois/Blanchette pourrait etre fortement affecte, et cela de diverses facons. Plusieurs scenarios d'impacts sont envisageables, notamment les risques d'inondation, d'erosion et de pollution a travers une augmentation des precipitations et du ruissellement. Face a toutes ces menaces eventuelles, l'objectif de cette etude est d'evaluer les impacts potentiels des changements climatiques sur les risques d'erosion et de pollution a l'echelle du bassin versant Iroquois/Blanchette. Pour ce faire, la version canadienne de l'equation universelle revisee des pertes en sol RUSLE-CAN et le modele hydrologique SWAT ( Soil and Water Assessment Tool) ont ete utilises pour modeliser les risques d'erosion et de pollution au niveau dans la zone d'etude. Les donnees utilisees pour realiser ce travail proviennent de sources diverses et variees (teledetections, pedologiques, topographiques, meteorologiques, etc.). Les simulations ont ete realisees en deux etapes distinctes, d'abord dans les conditions actuelles ou l'annee 2013 a ete choisie comme annee de reference, ensuite en 2025 et 2050. Les resultats obtenus montrent une tendance a la hausse de la production de sediments dans les prochaines annees. La production maximale annuelle augmente de 8,34 % et 8,08 % respectivement en 2025 et 2050 selon notre scenario le plus optimiste, et de 29,99 % en 2025 et 29,72 % en 2050 selon le scenario le plus pessimiste par rapport a celle

There were also some relatively new adaptation practices such as the use of detergents, nails, beans and bitter leaf to aid fermentation, especially for the production of akpu and alibo. In terms of profitability, the four adaptation practices with high profitability indices were, in order of decreasing importance, increased use of sundrying, water, hired labor and palm oil. The study therefore recommends that breeding of improved varieties of cassava should begin to target those that are tolerant to excessive and extreme fluctuations of rainfall, heat and flood. In addition, the adaptation practices with high profitability indices should be vigorously disseminated. Also, further studies, especially on the chemistry of the observed relatively new adaptation practices should be explored.

    Protocol principles, creating a national climate change group in 2007 and launching its own national climate change program. The program's goal is to lower China's energy consumption per unit of GDP by 20% by 2010 compared with its 2005 level. Under a medium to long-term sustainable development plan, the share of sustainable energies in the overall energy mix will increase to 10% by 2010 and to 15% by 2020. Before the Copenhagen conference, China indicated that it was expecting the United States and Europe to commit to reducing their emissions by 40% and to devote 1% of their GDP to technology transfer towards developing countries by 2020. The Bush Administration used the argument that 'the American way of life is not negotiable' to justify the refusal of the United States to adhere to the Kyoto Protocol. Today, the United States returns to the discussion table in a more open frame of mind. The administration of Barack Obama has decided to become more involved and cooperate more with China and India on climate change. In late June, the American president succeeded in getting his climate change bill through the US House of Representatives. The climate bill, which is still up before the Senate, aims to reduce GHG emissions (particularly CO{sub 2}) by 17% before 2020 compared with the 2005 level. It also promotes the development of clean energies and provides for the creation of a cap and trade emissions trading system. Under this system, emissions allowances are either sold or given to the most vulnerable industries. The sales revenue would be used to fund the development of clean energies, among other things. The EU-15 member states are close to reaching the targets set at Kyoto. What about EU-27 member states? At the late September summit in Pittsburgh, the G20 countries, which include the most industrialized countries as well as the large emerging countries of China, India and Brazil, agreed to phase out subsidies for fossil energy sources over the

Since then, 'MIRD Dose Estimate Report' (from the 1 to 12) and 'Pamphlets', of great utility for the dose calculations, were published. The MIRD system was planned essentially for the calculation of doses received by the patients during nuclear medicine diagnostic procedures.

This reflection leads to more general reflection: what contents, for what PSA? This is why, in Part Two, we will try to offer a framework for definition of the criteria a PSA should satisfy to meet the clearly identified needs. Finally, Part Three will quickly summarize the questions approached in the first two parts, as an introduction to the debate. 15 refs.

On attend une remontée des essences en altitude qui pourrait conduire à une diminution des résineux et des espèces du subalpin. Ces changements d’essences pourraient avoir un impact négatif sur la biodiversité et sur la production de bois d’œuvre. On observe cependant également une augmentation de la productivité favorable à la production de bois énergie et au moins temporairement de bois d’œuvre, ainsi qu’au stockage de carbone. Face à une augmentation possible des évènements climatiques extrêmes, les changements de végétation pourront être marqués par des épisodes de dépérissements, très négatifs pour la filière économique, la protection contre les risques naturels et la biodiversité. Le changement climatique affectera la forêt également de manière indirecte en augmentant la demande en énergie renouvelable et en stockage de carbone.

    The present work has as it main objective the development of bioindicator methodology for use of soil biorremediation criteria and environmental assessment evaluation upon the actual soil biorremediation status quantification. In order to do so morphophysiological aspects of Avena sativa and Barbarea verna, were determinated under greenhouse conditions for a dilution series of contaminated soil with the non contaminated one. A quantification scale model was proposed report the based on the statistical analysis for the defined morphophisyological parameters. Therefore, it has possible to quantigicate phytoxicity and construct phytotoxicity curves for the contaminated soil dilution series. It was possible to conclude that the developed methodology can be used as a criteria of soil actual biorremediation status. (author)

    Several methodologies are available for screening human populations for exposure to ionizing radiation. Of these, aberration frequency determined in peripheral blood lymphocytes is the best developed. Individual exposures to large doses can easily be quantitated, and population exposures to occupational levels can be detected. However, determination of exposures to the very low doses anticipated from a low-level radioactive waste disposal site is more problematical. Aberrations occur spontaneously, without known cause. Exposure to radiation induces no new or novel types, but only increases their frequency. The limitations of chromosomal aberration dosimetry for detecting low level radiation exposures lie mainly in the statistical signal to noise'' problem, the distribution of aberrations among cells and among individuals, and the possible induction of aberrations by other environmental occupational or medical exposures. However, certain features of the human peripheral lymphocyte-chromosomal aberration system make it useful in screening for certain types of exposures. Future technical developments may make chromosomal aberration dosimetry more useful for low-level radiation exposures. Other methods, measuring gene mutations or even minute changes on the DNA level, while presently less will developed techniques, may eventually become even more practical and sensitive assays for human radiation exposure. 15 refs.

    Full Text Available Les écosystèmes alpins vont être grandement influencés par les changements climatiques à venir, mais d’autres facteurs, tels que l’utilisation des terres ou les espèces invasives, pourront aussi jouer un rôle important. Le climat peut influencer les écosystèmes à différents niveaux, et nous en décrivons certains, en mettant l’accent sur les méthodes utilisées et les données disponibles. Le climat peut d’abord modifier la phénologie des espèces, comme la date de floraison des plantes ou la date d’éclosion des insectes. Il peut ensuite affecter directement la démographie des espèces (survie, reproduction, dispersion et donc à terme leur répartition. Il peut enfin agir sur les interactions entre espèces – le couvert neigeux par exemple modifie le succès de certains prédateurs. Une caractéristique des écosystèmes alpins est la présence d’un manteau neigeux important et pourtant l’influence de la neige reste relativement mal connue, en particulier pour des raisons logistiques. Même si nous avons fait des progrès importants dans le développement de modèles prédictifs, surtout pour ce qui est de la répartition des plantes alpines, il reste à mettre en place des réseaux d’observations et d’expériences permettant de mieux tenir compte de la variabilité des écosystèmes alpins et des interactions avec le climat.Alpine ecosystems will be greatly impacted by climatic change, but other factors, such as land use and invasive species, are likely to play an important role too. Climate can influence ecosystems at several levels. We describe some of them, stressing methodological approaches and available data. Climate can modify species phenology, such as flowering date of plants and hatching date in insects. It can also change directly population demography (survival, reproduction, dispersal, and therefore species distribution. Finally it can effect interactions among species –snow cover for example

    1991-01-01

    In recent literature it has been suggested that consumers need have no knowledge of product quality as a number of quality indicators (or signals) may be used as substitutes. Very little attention has been paid to the empirical verification of these studies. The present paper is devoted...... to the issue of how well these indicators perform, using market data provided by consumer magazines from 3 countries. The results strongly indicate that price is a poor quality indicator. The paper also presents some evidence which suggests that seller reputation and easily observable characteristics are also...

Il établit un parallèle entre le développement pris au niveau international de la négociation entre Etats d’une part, et la pauvreté au niveau d’une collectivité d’autre part. Dans les deux cas, il s’agit à la fois d’un principe moral essentiel, mais aussi d’une condition centrale des consensus et donc de la réussite des politiques face au défi climatique. La question de l’équité renvoie aussi très vite au changement nécessaire des modes de vie vers plus de sobriété.The article debates Equity Issues in the Climate Change debate is debated. A parallel is set between the development issues at the international level of negotiations between States, and poverty alleviation at the local community level. In both cases, the discussions stem from an essential moral principle, but also as a requisite for consensus and thus a condition of success of climate change policies to combat Climate Change. The issue of equity brings also forward the necessary modification of consumption patterns, into more frugal modes.

    1984-08-01

    Probabilistic Risk Assessments (PRAs) for six nuclear power plants were examined to gain insight into how the choice of analytical methods can affect the results of PRAs. The PRA sreflectope considered was limited to internally initiated accidents sequences through core melt. For twenty methodological topic areas, a baseline or minimal methodology was specified. The choice of methods for each topic in the six PRAs was characterized in terms of the incremental level of effort above the baseline. A higher level of effort generally reflects a higher level of detail or a higher degree of sophistication in the analytical approach to a particular topic area. The impact on results was measured in terms of how additional effort beyond the baseline level changed the relative importance and ordering of dominant accident sequences compared to what would have been observed had methods corresponding to the baseline level of effort been employed. This measure of impact is a more useful indicator of how methods affect perceptions of plant vulnerabilities than changes in core melt frequency would be. However, the change in core melt frequency was used as a secondary measure of impact for nine topics where availability of information permitted. Results are presented primarily in the form of effort-impact matrices for each of the twenty topic areas. A suggested effort-impact profile for future PRAs is presented

    Journal article about Reliability Centered Maintenance (RCM) methodologies used by United Space Alliance, LLC (USA) in support of the Space Shuttle Program at Kennedy Space Center. The USA Reliability Centered Maintenance program differs from traditional RCM programs because various methodologies are utilized to take advantage of their respective strengths for each application. Based on operational experience, USA has customized the traditional RCM methodology into a streamlined lean logic path and has implemented the use of statistical tools to drive the process. USA RCM has integrated many of the L6S tools into both RCM methodologies. The tools utilized in the Measure, Analyze, and Improve phases of a Lean Six Sigma project lend themselves to application in the RCM process. All USA RCM methodologies meet the requirements defined in SAE JA 1011, Evaluation Criteria for Reliability-Centered Maintenance (RCM) Processes. The proposed article explores these methodologies.

  3. Formalizing the ISDF Software Development Methodology

    Directory of Open Access Journals (Sweden)

    Mihai Liviu DESPA

    2015-01-01

    Full Text Available The paper is aimed at depicting the ISDF software development methodology by emphasizing quality management and software development lifecycle. The ISDF methodology was built especially for innovative software development projects. The ISDF methodology was developed empirically by trial and error in the process of implementing multiple innovative projects. The research process began by analysing key concepts like innovation and software development and by settling the important dilemma of what makes a web application innovative. Innovation in software development is presented from the end-user, project owner and project manager’s point of view. The main components of a software development methodology are identified. Thus a software development methodology should account for people, roles, skills, teams, tools, techniques, processes, activities, standards, quality measuring tools, and team values. Current software development models are presented and briefly analysed. The need for a dedicated innovation oriented software development methodology is emphasized by highlighting shortcomings of current software development methodologies when tackling innovation. The ISDF methodology is presented in the context of developing an actual application. The ALHPA application is used as a case study for emphasizing the characteristics of the ISDF methodology. The development life cycle of the ISDF methodology includes research, planning, prototyping, design, development, testing, setup and maintenance. Artefacts generated by the ISDF methodology are presented. Quality is managed in the ISDF methodology by assessing compliance, usability, reliability, repeatability, availability and security. In order to properly asses each quality component a dedicated indicator is built. A template for interpreting each indicator is provided. Conclusions are formulated and new related research topics are submitted for debate.

    1986-01-01

    It is the aim of this paper, intended more as a general outline than a comprehensive review, to elucidate the most prominent events in the sequence of radiation induced cytological changes in the hemopoietic system taking its functional organisation and the cytokinetics of blood cell production into consideration. As could be shown, there are about ten different categories of quantitative and qualitative parameters based on methods ranging from stem cell determinations to tests for mature blood cell function that in principle are available for assessment of radiation damage to the bone marrow and that have been applied to men exposed to ionizing radiation. Some of these indicator systems have proven for a long period of time to be of essential value and to be quite feasible in practice under routine conditions. Considerable methodological progress, however, is needed for others before decisions about their practical applicability can be made. (orig.)

    Moner, David; Maldonado, José Alberto; Robles, Montserrat

    2018-03-01

    Clinical Information Models (CIMs) expressed as archetypes play an essential role in the design and development of current Electronic Health Record (EHR) information structures. Although there exist many experiences about using archetypes in the literature, a comprehensive and formal methodology for archetype modeling does not exist. Having a modeling methodology is essential to develop quality archetypes, in order to guide the development of EHR systems and to allow the semantic interoperability of health data. In this work, an archetype modeling methodology is proposed. This paper describes its phases, the inputs and outputs of each phase, and the involved participants and tools. It also includes the description of the possible strategies to organize the modeling process. The proposed methodology is inspired by existing best practices of CIMs, software and ontology development. The methodology has been applied and evaluated in regional and national EHR projects. The application of the methodology provided useful feedback and improvements, and confirmed its advantages. The conclusion of this work is that having a formal methodology for archetype development facilitates the definition and adoption of interoperable archetypes, improves their quality, and facilitates their reuse among different information systems and EHR projects. Moreover, the proposed methodology can be also a reference for CIMs development using any other formalism. Copyright © 2018 Elsevier Inc. All rights reserved.

  12. Mexican energy policy and sustainability indicators

    Sheinbaum-Pardo, Claudia; Ruiz-Mendoza, Belizza Janet; Rodríguez-Padilla, Víctor

    2012-01-01

    The authors analyze the Mexican energy policy taking as reference the methodological framework for sustainable energy development proposed by the Economic Commission for Latin America and the Caribbean. This methodology takes eight related indicators to the social, environmental and economic dimensions in order to calculate a general sustainability indicator for the energy sector. In this methodology, the weight of each dimension is different; namely, the social and environmental issues have less relevance than the economic issues. The authors use this methodology because government institutions as the Department of Energy and the Department of Environment and Natural Resources have used some indicators from such a methodology to propose plans, programs, projects and bills. Authors know of the existence of other methodologies about sustainability. Nonetheless, opting for the Economic Commission for Latin America and the Caribbean's methodology is convenient because this organization is a respectable authority for civil servants from the Mexican institutions. Our objective is just to contrast the sustainability grade of the energy sector between 1990 and 2008 for Mexico whose government started reforms in the 1990s. It concludes that those reforms did not bring about a higher sustainability level for the energy sector. - Highlights: ► We used the OLADE, CEPAL and GTZ's methodology to calculate sustainability indicators for the Mexican energy sector. ► We studied the Mexican energy policy from 1990 to date and presented it. ► Currently, the Mexican energy sector is less sustainable than in 1990.

    International Nuclear Information System (INIS)

    McLachlan, N.; Reed, J.; Metcalfe, M.P.

    1996-01-01

    To demonstrate the safety of its gas-cooled graphite-moderated AGR reactors, nuclear safety assessments of the cores are based upon a methodology which demonstrates no component failures, geometrical stability of the structure and material properties bounded by a database. All AGRs continue to meet these three criteria. However, predictions of future core behaviour indicate that the safety case methodology will eventually need to be modified to deal with new phenomena. A new approach to the safety assessment of the cores is currently under development, which can take account of these factors while at the same time providing the same level of protection for the cores. This approach will be based on the functionality of the core: unhindered movement of control rods, continued adequate cooling of the fuel and the core, continued ability to charge and discharge fuel.

    The fallout from a nuclear explosion has the potential to injure or kill 100,000 or more people through exposure to external gamma (fallout) radiation. Existing buildings can reduce radiation exposure by placing material between fallout particles and exposed people. Lawrence Livermore National Laboratory was tasked with developing an operationally feasible methodology that could improve fallout casualty estimates. The methodology, called a Regional Shelter Analysis, combines the fallout protection that existing buildings provide civilian populations with the distribution of people in various locations. The Regional Shelter Analysis method allows the consideration of (a) multiple building types and locations within buildings, (b) country specific estimates, (c) population posture (e.g., unwarned vs. minimally warned), and (d) the time of day (e.g., night vs. day). The protection estimates can be combined with fallout predictions (or measurements) to (a) provide a more accurate assessment of exposure and injury and (b) evaluate the effectiveness of various casualty mitigation strategies. This report describes the Regional Shelter Analysis methodology, highlights key operational aspects (including demonstrating that the methodology is compatible with current tools), illustrates how to implement the methodology, and provides suggestions for future work.

  16. Environmental indicators for evaluating properties

    Directory of Open Access Journals (Sweden)

    Mario Grosso

    2015-06-01

    Full Text Available Property evaluation for tax purposes has traditionally relied on urban and building criteria, mostly resulting from concepts driven by the commercial attractiveness of the property under evaluation, its building and the site itself. Due to the world climate and ecological crisis, awareness has risen about the need for other indicators, which can evaluate the quality of a property, even referring to its potential environmental impact. Technical standards for the evaluation of buildings’ environmental sustainability, which have been developed since the first years of this century, both nationally and internationally, take into account the impact of the building and its relevance for the life-cycle of materials and elements, with reference to the three sectors of sustainability: environmental, economic and social. The social sector includes indicators referring to the user’s health and comfort, which also interact with the morphological and spatial characteristics of the building. However, there is a lack of methodological tools for the evaluation of said indicators and existing ones are mainly of a qualitative type. This paper suggests a methodological approach for the quantitative evaluation of sustainability indicators, relying on the accessibility of a site’s climate resources by the property, as a criterion to evaluate the potential for the reduction of negative environmental impact, as well as a criterion to improve users’ life quality.

    Full Text Available Selecting indicators for assessing the quality of life at the regional level is not unambigous. Currently, there are no precisely defined indicators that would give comprehensive information about the quality of life on a local level. In this paper we focus on the determination (selection of groups of indicators that can be interpreted, on the basis of studied literature, as factors characterizing the quality of life. Furthermore, on the application of methods to reduce the dimensionality of these indicators, from the source of the database CULS KROK, which provides statistics on the regional and districts level. To reduce the number of indicators and the subsequent creation of derived variables that capture the relationships between selected indicators multivariate statistical analysis methods, especially method of principal components and factor analysis were used.

  1. Soft Systems Methodology

    Science.gov (United States)

    Checkland, Peter; Poulter, John

    Soft systems methodology (SSM) is an approach for tackling problematical, messy situations of all kinds. It is an action-oriented process of inquiry into problematic situations in which users learn their way from finding out about the situation, to taking action to improve it. The learning emerges via an organised process in which the situation is explored using a set of models of purposeful action (each built to encapsulate a single worldview) as intellectual devices, or tools, to inform and structure discussion about a situation and how it might be improved. This paper, written by the original developer Peter Checkland and practitioner John Poulter, gives a clear and concise account of the approach that covers SSM's specific techniques, the learning cycle process of the methodology and the craft skills which practitioners develop. This concise but theoretically robust account nevertheless includes the fundamental concepts, techniques, core tenets described through a wide range of settings.

    This report presents the general methodology and best practice approaches which combine proven existing techniques for sampling and characterisation to assess the contamination of soils prior to remediation. It is based on feedback of projects conducted by main French nuclear stakeholders involved in the field of remediation and dismantling (EDF, CEA, AREVA and IRSN). The application of this methodology will enable the project managers to obtain the elements necessary for the drawing up of files associated with remediation operations, as required by the regulatory authorities. It is applicable to each of the steps necessary for the piloting of remediation work-sites, depending on the objectives targeted (release into the public domain, re-use, etc.). The main part describes the applied statistical methodology with the exploratory analysis and variogram data, identification of singular points and their location. The results obtained permit assessment of a mapping to identify the contaminated surface and subsurface areas. It stakes the way for radiological site characterisation since the initial investigations from historical and functional analysis to check that the remediation objectives have been met. It follows an example application from the feedback of the remediation of a contaminated site on the Fontenay aux Roses facility. It is supplemented by a glossary of main terms used in the field from different publications or international standards. This technical report is a support of the ISO Standard ISO ISO/TC 85/SC 5 N 18557 'Sampling and characterisation principles for soils, buildings and infrastructures contaminated by radionuclides for remediation purposes'.

    Quality indicators are used to measure quality of care and enable benchmarking. An overview of all existing hip fracture quality indicators is lacking. The primary aim was to identify quality indicators for hip fracture care reported in literature, hip fracture audits, and guidelines. The secondary aim was to compose a set of methodologically sound quality indicators for the evaluation of hip fracture care in clinical practice. A literature search according to the PRISMA guidelines and an internet search were performed to identify hip fracture quality indicators. The indicators were subdivided into process, structure, and outcome indicators. The methodological quality of the indicators was judged using the Appraisal of Indicators through Research and Evaluation (AIRE) instrument. For structure and process indicators, the construct validity was assessed. Sixteen publications, nine audits and five guidelines were included. In total, 97 unique quality indicators were found: 9 structure, 63 process, and 25 outcome indicators. Since detailed methodological information about the indicators was lacking, the AIRE instrument could not be applied. Seven indicators correlated with an outcome measure. A set of nine quality indicators was extracted from the literature, audits, and guidelines. Many quality indicators are described and used. Not all of them correlate with outcomes of care and have been assessed methodologically. As methodological evidence is lacking, we recommend the extracted set of nine indicators to be used as the starting point for further clinical research. Future research should focus on assessing the clinimetric properties of the existing quality indicators.

    A. I. Korobko

    2017-06-01

    Full Text Available The paper describes the methodology for developing new test methods and forming solutions for the development of new test methods. The basis of the methodology for developing new test methods is the individual elements of the system and process approaches. They contribute to the development of an effective research strategy for the object, the study of interrelations, the synthesis of an adequate model of the test method. The effectiveness of the developed test method is determined by the correct choice of the set of concepts, their interrelations and mutual influence. This allows you to solve the tasks assigned to achieve the goal. The methodology is based on the use of fuzzy cognitive maps. The question of the choice of the method on the basis of which the model for the formation of solutions is based is considered. The methodology provides for recording a model for a new test method in the form of a finite set of objects. These objects are significant for the test method characteristics. Then a causal relationship is established between the objects. Further, the values of fitness indicators and the observability of the method and metrological tolerance for the indicator are established. The work is aimed at the overall goal of ensuring the quality of tests by improving the methodology for developing the test method.

    Babiuch, W.M.; Farhar, B.C.

    1994-03-01

    Stakeholder analysis allows analysts to identify how parties might be affected by government projects. This process involves identifying the likely impacts of a proposed action and stakeholder groups affected by that action. Additionally, the process involves assessing how these groups might be affected and suggesting measures to mitigate any adverse effects. Evidence suggests that the efficiency and effectiveness of government actions can be increased and adverse social impacts mitigated when officials understand how a proposed action might affect stakeholders. This report discusses how to conduct useful stakeholder analyses for government officials making decisions on energy-efficiency and renewable-energy technologies and their commercialization. It discusses methodological issues that may affect the validity and reliability of findings, including sampling, generalizability, validity, ``uncooperative`` stakeholder groups, using social indicators, and the effect of government regulations. The Appendix contains resource directories and a list of specialists in stakeholder analysis and involvement.

    Heinberg, C.L.; Roberts, N.J.

    1987-01-01

    This paper discusses an evaluation methodology which is used for inventory differences at the Los Alamos National Laboratory. It is recognized that there are various methods which can be, and are being, used to evaluate process inventory differences at DOE facilities. The purpose of this paper is to share our thoughts on the subject and our techniques with those who are responsible for the evaluation of inventory differences at their facility. One of the most dangerous aspects of any evaluation technique, especially one as complex as most inventory difference evaluations tend to be, is to fail to look at the tools being used as indicators. There is a tendency to look at the results of an evaluation by one technique as an absolute. At the Los Alamos National Laboratory, several tools are used and the final evaluation is based on a combination of the observed results of a many-faceted evaluation. The tools used and some examples are presented

Several pluri-disciplinary and interdisciplinary aspects of microscopics research are also discussed in the present scientific context. The need for an equilibrium between individual tendencies and collective constraints required by team work, already formulated thirty years ago by Frederic Joliot, is particularly stressed in the present conjuncture of Nuclear Research favouring very large team projects and discouraging individual initiatives. The increasing importance of the science of science (due to their multiple social, economical, ecological aspects) and the stronger competition between national and international tendencies of scientific (and technical) cooperation are also discussed.

    Directory of Open Access Journals (Sweden)

    Ndour, A.

    2017-01-01

    Full Text Available Climate change and cotton production in Senegal: alternate dissemination strategies of varieties. Description of the subject. Climate change challenges the strategy of varietal diffusion, employed by the Senegalese cotton company (SODEFITEX, based on the distinction of two cultivars: one adapted to humid conditions and the other to drought. Based on data collected in an experimental station and farmer plots from 2004 to 2011, the study provides an assessment of that strategy. Objectives. The aim of the study was to evaluate both the methodology used for varietal selection and the performance of released and candidate cultivars, under contrasted water environments due to variability in rainfall (spatial and temporal and crop management. Method. The methodology used allowed the identification of the occurrence of severe water stress during the critical cotton development phases (flowering and boll development and its effect on seed cotton yield and fiber quality. The resulting indicator of plant water status was then inserted into our statistical analysis as an environmental covariate. Results. The resulting indicator allowed the discrimination of seed cotton yield in the experimental station as well as in on-farm experiments. Despite an effect of cultivar on ginning outturn and fiber quality, all cultivars showed similar resilience to water status. Conclusions. Despite a lack of cultivar adaptation to water stress, results support the adoption of a single cultivar in the whole production basin. However, the diffusion strategy would benefit from a better consideration of farmer cropping conditions, which would thus allow for the evaluation of cultivars by the producers.

    A requirement for RHIC data plotting software and physics analysis is the correlation of data from all accelerator data gathering systems. Data correlation provides the capability for a user to request a plot of multiple data channels vs. time, and to make meaningful time-correlated data comparisons. The task of data correlation for RHIC requires careful consideration because data acquisition triggers are generated from various asynchronous sources including events from the RHIC Event Link, events from the two Beam Sync Links, and other unrelated clocks. In order to correlate data from asynchronous acquisition systems a common time reference is required. The RHIC data correlation methodology will allow all RHIC data to be converted to a common wall clock time, while still preserving native acquisition trigger information. A data correlation task force team, composed of the authors of this paper, has been formed to develop data correlation design details and provide guidelines for software developers. The overall data correlation methodology will be presented in this paper

    1990-01-01

    An added challenge for the designers of large scale systems such as Space Station Freedom is the appropriate incorporation of intelligent system technology (artificial intelligence, expert systems, knowledge-based systems, etc.) into their requirements and design. This presentation will describe a view of systems engineering which successfully addresses several aspects of this complex problem: design of large scale systems, design with requirements that are so complex they only completely unfold during the development of a baseline system and even then continue to evolve throughout the system's life cycle, design that involves the incorporation of new technologies, and design and development that takes place with many players in a distributed manner yet can be easily integrated to meet a single view of the requirements. The first generation of this methodology was developed and evolved jointly by ISX and the Lockheed Aeronautical Systems Company over the past five years on the Defense Advanced Research Projects Agency/Air Force Pilot's Associate Program, one of the largest, most complex, and most successful intelligent systems constructed to date. As the methodology has evolved it has also been applied successfully to a number of other projects. Some of the lessons learned from this experience may be applicable to Freedom.

    To ensure the required and desired operation over the plant lifetime, the performance analysis for the SMART NSSS design is done by means of the specified analysis methodologies for the performance related design basis events(PRDBE). The PRDBE is an occurrence(event) that shall be accommodated in the design of the plant and whose consequence would be no more severe than normal service effects of the plant equipment. The performance analysis methodology which systematizes the methods and procedures to analyze the PRDBEs is as follows. Based on the operation mode suitable to the characteristics of the SMART NSSS, the corresponding PRDBEs and allowable range of process parameters for these events are deduced. With the developed control logic for each operation mode, the system thermalhydraulics are analyzed for the chosen PRDBEs using the system analysis code. Particularly, because of different system characteristics of SMART from the existing commercial nuclear power plants, the operation mode, PRDBEs, control logic, and analysis code should be consistent with the SMART design. This report presents the categories of the PRDBEs chosen based on each operation mode and the transition among these and the acceptance criteria for each PRDBE. It also includes the analysis methods and procedures for each PRDBE and the concept of the control logic for each operation mode. Therefore this report in which the overall details for SMART performance analysis are specified based on the current SMART design, would be utilized as a guide for the detailed performance analysis

    1999-01-01

    The methodology presented in this document was developed to provide a means of calculating the RH ratios to use in developing useful graphic illustrations. The RH equation, as presented in this methodology, is primarily a collection of key factors relevant to understanding the hazards and risks associated with projected risk management activities. The RH equation has the potential for much broader application than generating risk profiles. For example, it can be used to compare one risk management activity with another, instead of just comparing it to a fixed baseline as was done for the risk profiles. If the appropriate source term data are available, it could be used in its non-ratio form to estimate absolute values of the associated hazards. These estimated values of hazard could then be examined to help understand which risk management activities are addressing the higher hazard conditions at a site. Graphics could be generated from these absolute hazard values to compare high-hazard conditions. If the RH equation is used in this manner, care must be taken to specifically define and qualify the estimated absolute hazard values (e.g., identify which factors were considered and which ones tended to drive the hazard estimation)

    Perspectives of energy consumption reduction linked to global warming are bringing a desire for actions relating to the mastering and the improvement of energy efficiency. In this context, from the French example of greater Besancon (Communaute d'Agglomeration du Grand Besancon (CAGB)), the research presented here wants to define an energy indicator useful to planners called 'Territory energy label': to measure how the urban area is situated energy wise in terms of the daily mobility of its inhabitants, the behaviour of whom is looked at in a prescriptive manner. [French] Les perspectives de reduction des consommations energetiques en lien avec le rechauffement climatique se traduisent par une volonte d'actions en matiere de maitrise et d'amelioration de l'efficacite energetique.

    To provide a scientific basis for risk assessment and decision making, the Chemical Migration and Risk Assessment (CMRA) Methodology was developed to simulate overland and instream toxic containment migration and fate, and to predict the probability of acute and chronic impacts on aquatic biota. The simulation results indicated that the time between the pesticide application and the subsequent runoff producing event was the most important factor determining the amount of the alachlor. The study also revealed that sediment transport has important effects on contaminant migration when sediment concentrations in receiving streams are high or contaminants are highly susceptible to adsorption by sediment. Although the capabilities of the CMRA methodology were only partially tested in this study, the results demonstrate that methodology can be used as a scientific decision-making tool for toxic chemical regulations, a research tool to evaluate the relative significance of various transport and degradation phenomena, as well as a tool to examine the effectiveness of toxic chemical control practice

    Full Text Available The aim of this research paper is to examine the Jordanian banks using financial soundness indicators. This is to establish if Jordanian banks were affected because of the 2007/2008 financial crisis and determine the underlying reasons. The research paper was conducted on 25 banks in Jordan listed in the countries securities exchange. The research methodology used consisted of examining the banks financial records in order to derive four crucial Basel III ratio such as the capital adequacy ratio, the leverage ratio, the liquidity ratio and finally the Total Provisions (As % Of Non-Performing Loans %. The results revealed that out of the four hypotheses under examination Jordan Banks do not meet Basel financial Indicators for Capital Adequacy Ratio, Jordan Banks does not meet Basel financial Indicators for Liquidity Ratio , Jordan Banks do not meet Basel financial Indicators for Leverage Ratio and Jordan Banks do not meet Basel financial Indicators for Total Provisions (As % Of Non-Performing Loans ratio. Only one hypothesis was accepted based on the research outcomes. The rest of the hypothesis was rejected since the average trend line did not go below the Basel III required ratio level. The general outcome of the research revealed that Jordanian banks were not affected significantly by the financial crisis.

  13. Indicators for Nuclear Power Development

    International Nuclear Information System (INIS)

    2015-01-01

    Considering the scale of nuclear power aspirations, the number of planned nuclear new builds and the prospects of a number of countries constructing their first nuclear power plants, there is a need to assess the broader context of nuclear energy programmes in areas of macro-and socioeconomic conditions, energy systems and nuclear power, and the environment. It is important to assess the degree to which introduction or expansion of nuclear power is beneficial under these specific circumstances. This publication provides a set of indicators for nuclear power development that can serve as a tool to help explore these issues. The indicators are meant to provide a first order assessment of the situation and identify the issues that present the benefits and challenges in a balanced and objective manner and thereby help guide more detailed evaluations in the next stage of planning and preparations. Methodology sheets are provided to help users in data collection, quantification and interpretation of the indicators. The application of the indicators set is flexible. Users can select a subset of indicators that are most relevant for the questions they wish to explore in a given study or decision making process

    Full Text Available Sensory science is the young but the rapidly developing field of the food industry. Actually, the great emphasis is given to the production of rapid techniques of data collection, the difference between consumers and trained panel is obscured and the role of sensory methodologists is to prepare the ways for evaluation, by which a lay panel (consumers can achieve identical results as a trained panel. Currently, there are several conventional methods of sensory evaluation of food (ISO standards, but more sensory laboratories are developing methodologies that are not strict enough in the selection of evaluators, their mechanism is easily understandable and the results are easily interpretable. This paper deals with mapping of marginal methods used in sensory evaluation of food (new types of profiles, CATA, TDS, napping.

    DOE Order 6430.1A, General Design Criteria (GDC), requires that DOE facilities be evaluated with respect to ''safety class items.'' Although the GDC defines safety class items, it does not provide a methodology for selecting safety class items. The methodology described in this paper was developed to assure that Safety Class Items at the Savannah River Site (SRS) are selected in a consistent and technically defensible manner. Safety class items are those in the highest of four categories determined to be of special importance to nuclear safety and, merit appropriately higher-quality design, fabrication, and industrial test standards and codes. The identification of safety class items is approached using a cascading strategy that begins at the 'safety function' level (i.e., a cooling function, ventilation function, etc.) and proceeds down to the system, component, or structure level. Thus, the items that are required to support a safety function are SCls. The basic steps in this procedure apply to the determination of SCls for both new project activities, and for operating facilities. The GDC lists six characteristics of SCls to be considered as a starting point for safety item classification. They are as follows: 1. Those items whose failure would produce exposure consequences that would exceed the guidelines in Section 1300-1.4, ''Guidance on Limiting Exposure of the Public,'' at the site boundary or nearest point of public access 2. Those items required to maintain operating parameters within the safety limits specified in the Operational Safety Requirements during normal operations and anticipated operational occurrences. 3. Those items required for nuclear criticality safety. 4. Those items required to monitor the release of radioactive material to the environment during and after a Design Basis Accident. Those items required to achieve, and maintain the facility in a safe shutdown condition 6. Those items that control Safety Class Item listed above

    2006-01-01

    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected. The gross data are submitted to a thorough review allowing the correction of abnormalities and the reconstitution of missing data. Each index is fashioned to take into account the economic activity in the various regions of the country as represented by each region's population. This demographic information represents a fair approximation of the weight of the regional economic activity. This document presents the calculation methodology of average, minimum and maximum weather indexes with the winter and summer regression equations for the different economical regions of Switzerland.

    2012-01-01

    Qualitative nurse researchers are required to make deliberate and sometimes complex methodological decisions about their work. Methodology in qualitative research is a comprehensive approach in which theory (ideas) and method (doing) are brought into close alignment. It can be difficult, at times, to understand the concept of methodology. The purpose of this research column is to: (1) define qualitative methodology; (2) illuminate the relationship between epistemology, ontology and methodology; (3) explicate the connection between theory and method in qualitative research design; and 4) highlight relevant examples of methodological decisions made within cardiovascular nursing research. Although there is no "one set way" to do qualitative research, all qualitative researchers should account for the choices they make throughout the research process and articulate their methodological decision-making along the way.

    This paper discusses the feasibility of using a teaching strategy called methodological pluralism, consisting of the use of various methodological resources in order to provide a meaningful learning. It is part of a doctoral thesis, which aims to investigate contributions to the use of traditional resources combined with digital technologies, in order to create autonomy for future teachers of Natural Sciences and Mathematics in relation to themes in Astronomy. It was offered an extension course at the "Federal Institution of Education, Science and Technology" in the North of Minas Gerais (FINMG), Campus Januaria, for thirty-two students of licentiate courses in Physics, Mathematics and Biological Sciences, involving themes of Astronomy, in order to search and contribute to improving the training of future teachers. The following aspects are used: the mixed methodology, with pre-experimental design, combined with content analysis. The results indicate the rates of students' prior knowledge in relation to Astronomy was low; meaningful learning indications of concepts related to Astronomy, and the feasibility of using digital resources Involving technologies, articulated with traditional materials in the teaching of Astronomy. This research sought to contribute to the initial teacher training, especially in relation to Astronomy Teaching, proposing new alternatives to promote the teaching of this area of knowledge, extending the methodological options of future teachers.

    Systematic review. To elucidate how performance indicators are currently used in spine surgery. The Patient Protection and Affordable Care Act has given significant traction to the idea that healthcare must provide value to the patient through the introduction of hospital value-based purchasing. The key to implementing this new paradigm is to measure this value notably through performance indicators. MEDLINE, CINAHL Plus, EMBASE, and Google Scholar were searched for studies reporting the use of performance indicators specific to spine surgery. We followed the Prisma-P methodology for a systematic review for entries from January 1980 to July 2016. All full text articles were then reviewed to identify any measure of performance published within the article. This measure was then examined as per the three criteria of established standard, exclusion/risk adjustment, and benchmarking to determine if it constituted a performance indicator. The initial search yielded 85 results among which two relevant studies were identified. The extended search gave a total of 865 citations across databases among which 15 new articles were identified. The grey literature search provided five additional reports which in turn led to six additional articles. A total of 27 full text articles and reports were retrieved and reviewed. We were unable to identify performance indicators. The articles presenting a measure of performance were organized based on how many criteria they lacked. We further examined the next steps to be taken to craft the first performance indicator in spine surgery. The science of performance measurement applied to spine surgery is still in its infancy. Current outcome metrics used in clinical settings require refinement to become performance indicators. Current registry work is providing the necessary foundation, but requires benchmarking to truly measure performance. 1.

    Since 1995, KNMI published a series of books(1), presenting an annual reconstruction of weather and climate in the Low Countries, covering the period AD 763-present, or roughly, the last millennium. The reconstructions are based on the interpretation of documentary sources predominantly and comparison with other proxies and instrumental observations. The series also comprises a number of classifications. Amongst them annual classifications for winter and summer temperature and for winter and summer dryness-wetness. The classification of temperature have been reworked into peer reviewed (2) series (AD 1000-present) of seasonal temperatures and temperature indices, the so called LCT (Low Countries Temperature) series, now incorporated in the Millennium databases. Recently we started a study to convert the dryness-wetness classifications into a series of precipitation; the so called LCP (Low Countries Precipitation) series. A brief outline is given here of the applied methodology and preliminary results. The WMO definition for meteorological drought has been followed being that a period is called wet respectively dry when the amount of precipitation is considerable more respectively less than usual (normal). To gain a more quantitative insight for four locations, geographically spread over the Low Countries area (De Bilt, Vlissingen, Maastricht and Uccle), we analysed the statistics of daily precipitation series, covering the period 1900-present. This brought us to the following definition, valid for the Low Countries: A period is considered as (very) dry respectively (very) wet if over a continuous period of at least 60 days (~two months) cq 90 days (~three months) on at least two out of the four locations 50% less resp. 50% more than the normal amount for the location (based on the 1961-1990 normal period) has been measured. This results into the following classification into five drought classes hat could be applied to non instrumental observations: Very wet period

    Gorokhov, V. G.

    Recently, we have reported on the definitions of nanotechnology as a new type of NanoTechnoScience and on the nanotheory as a cluster of the different natural and engineering theories. Nanotechnology is not only a new type of scientific-engineering discipline, but it evolves also in a “nonclassical” way. Nanoontology or nano scientific world view has a function of the methodological orientation for the choice the theoretical means and methods toward a solution to the scientific and engineering problems. This allows to change from one explanation and scientific world view to another without any problems. Thus, nanotechnology is both a field of scientific knowledge and a sphere of engineering activity, in other words, NanoTechnoScience is similar to Systems Engineering as the analysis and design of large-scale, complex, man/machine systems but micro- and nanosystems. Nano systems engineering as well as Macro systems engineering includes not only systems design but also complex research. Design orientation has influence on the change of the priorities in the complex research and of the relation to the knowledge, not only to “the knowledge about something”, but also to the knowledge as the means of activity: from the beginning control and restructuring of matter at the nano-scale is a necessary element of nanoscience.

    This paper reports on the tangible progress that has been made in clarifying the underlying processes that affect both the likelihood of war in general and of nuclear war in particular. It also illustrates how difficult it is to make progress in this area. Nonetheless, what has been achieved should not be minimized. We have learned a good deal on both the theoretical and the methodological fronts and, perhaps, most important, we have learned a good deal about the limits of our knowledge. Knowledge of our ignorance---especially in a policy domain where confident, even glib, causal assertions are so common---can be a major contribution in itself. The most important service the behavioral and social sciences can currently provide to the policy making community may well be to make thoughtful skepticism respectable: to sensitize those who make key decisions to the uncertainty surrounding our understanding of international conflict and to the numerous qualifications that now need to be attached to simple causal theories concerning the origins of war

    The term ''radioecology'' has been widely recognized in scientific and technical societies. At the same time, this scientific school (radioecology) does not have a precise/generally acknowledged structure, unified methodical basis, fixed subjects of investigation, etc. In other words, radioecology is a vast, important but rather amorphous conglomerate of various ideas, amalgamated mostly by their involvement in biospheric effects of ionizing radiation and some conceptual stereotypes. This paradox was acceptable up to a certain time. However, with the termination of the Cold War and because of remarkable political changes in the world, it has become possible to convert the problem of environmental restoration from the scientific sphere in particularly practical terms. Already the first steps clearly showed an imperfection of existing technologies, managerial and regulatory schemes; lack of qualified specialists, relevant methods and techniques; uncertainties in methodology of decision-making, etc. Thus, building up (or maybe, structuring) of special scientific and technological basis, which the authors call ''engineering radioecology'', seems to be an important task. In this paper they endeavored to substantiate the last thesis and to suggest some preliminary ideas concerning the subject matter of engineering radioecology

This especially applies to the case when the term “performance improvement” implies efficiency improvement measured by indicators, such as ROI, ROE, ROA, or ROVA/ROI. Such tasks are very complex, requiring implementation by means of project management. In this paper, the authors propose a methodological approach to improving the organizational performance of a large enterprise.

    Establishment of guidance for the protection of workers and members of the public from radiation exposures necessitates estimation of the radiation dose to tissues of the body at risk. The dosimetric methodology formulated by the International Commission on Radiological Protection (ICRP) is intended to be responsive to this need. While developed for radiation protection, elements of the methodology are often applied in addressing other radiation issues; e.g., risk assessment. This chapter provides an overview of the methodology, discusses its recent extension to age-dependent considerations, and illustrates specific aspects of the methodology through a number of numerical examples

  1. Country report: a methodology

    International Nuclear Information System (INIS)

    Colin, A.

    2013-01-01

    This paper describes a methodology which could be applicable to establish a country report. In the framework of nuclear non proliferation appraisal and IAEA safeguards implementation, it is important to be able to assess the potential existence of undeclared nuclear materials and activities as undeclared facilities in the country under review. In our views a country report should aim at providing detailed information on nuclear related activities for each country examined taken 'as a whole' such as nuclear development, scientific and technical capabilities, etc. In order to study a specific country, we need to know if there is already an operating nuclear civil programme or not. In the first case, we have to check carefully if it could divert nuclear material, if there are misused declared facilities or if they operate undeclared facilities and conduct undeclared activities aiming at manufacturing nuclear weapon. In the second case, we should pay attention to the development of a nuclear civil project. A country report is based on a wide span of information (most of the time coming from open sources but sometimes coming also from confidential or private ones). Therefore, it is important to carefully check the nature and the credibility (reliability?) of these sources through cross-check examination. Eventually, it is necessary to merge information from different sources and apply an expertise filter. We have at our disposal a lot of performing tools to help us to assess, understand and evaluate the situation (cartography, imagery, bibliometry, etc.). These tools allow us to offer the best conclusions as far as possible. The paper is followed by the slides of the presentation. (author)

    Searching for life in astromaterials to be delivered from the future missions to extraterrestrial bodies is undoubtedly related to studies of the properties and signatures of living microbial cells and microfossils on Earth. As model terrestrial analogs of Martian polar subsurface layers are often regarded the Antarctic glacier and Earth permafrost habitats where alive microbial cells preserved viability for millennia years due to entering the anabiotic state. For the future findings of viable microorganisms in samples from extraterrestrial objects, it is important to use a combined methodology that includes classical microbiological methods, plating onto nutrient media, direct epifluorescence and electron microscopy examinations, detection of the elemental composition of cells, radiolabeling techniques, PCR and FISH methods. Of great importance is to ensure authenticity of microorganisms (if any in studied samples) and to standardize the protocols used to minimize a risk of external contamination. Although the convincing evidence of extraterrestrial microbial life will may come from the discovery of living cells in astromaterials, biomorphs and microfossils must also be regarded as a target in search of life evidence bearing in mind a scenario that alive microorganisms had not be preserved and underwent mineralization. Under the laboratory conditions, processes that accompanied fossilization of cyanobacteria were reconstructed, and artificially produced cyanobacterial stromatolites resembles by their morphological properties those found in natural Earth habitats. Regarding the vital importance of distinguishing between biogenic and abiogenic signatures and between living and fossil microorganisms in analyzed samples, it is worthwhile to use some previously developed approaches based on electron microscopy examinations and analysis of elemental composition of biomorphs in situ and comparison with the analogous data obtained for laboratory microbial cultures and

  6. Indicators System for Poverty Measurement

    Directory of Open Access Journals (Sweden)

    2006-10-01

    Full Text Available Poverty represents a life aspect which is focusing the attention of both the macroeconomic analysis and the international comparisons. In order to measure the level being recorded by this phenomenon, there is a system of indicators which are used in order to underline, in a correlated manner, a number of aspects which are characterizing, quality and quantity wise, the evolution of the poverty in a specific country or, to a larger extent, through comparative surveys, at international level. Despite the fact that they are not the only instrument being used within the process of comparison of the stages of social and economic development at the international level, however the poverty indicators are providing a clear significance to the worked out surveys. In fact, the very purpose of the economic activity consists of increasing welfare and, as much as possible, at least reducing, if not eradicating, the poverty. The present work is broadly presenting the methodology as well as, both theoretical and practical, the way of computing the poverty, making a synthesis of the specific used indicators.

  7. Energy indicators for sustainable development

    2007-01-01

    Energy is an essential factor in overall efforts to achieve sustainable development. Countries striving to this end are seeking to reassess their energy systems with a view toward planning energy programmes and strategies in line with sustainable development goals and objectives. This paper summarizes the outcome of an international partnership initiative on indicators for sustainable energy development that aims to provide an analytical tool for assessing current energy production and use patterns at a national level. The proposed set of energy indicators represents a first step of a consensus reached on this subject by five international agencies-two from the United Nations system (the Department of Economic and Social Affairs and the International Atomic Energy Agency), two from the European Union (Eurostat and the European Environment Agency) and one from the Organization for Economic Cooperation and Development (the International Energy Agency). Energy and environmental experts including statisticians, analysts, policy makers and academics have started to implement general guidelines and methodologies in the development of national energy indicators for use in their efforts to monitor the effects of energy policies on the social, economic and environmental dimensions of sustainable development

    The purpose of risk-based indicators is to monitor plant safety. Safety is measured by monitoring the potential for core melt (core-melt frequency) and the public risk. Targets for these measures can be set consistent with NRC safety goals. In this process, the performance of safety systems, support systems, major components, and initiating events can be monitored using measures such as unavailability, failure or occurrence frequency. The changes in performance measures and their trends are determined from the time behavior of monitored measures by differentiation between stochastical and actual variations. Therefore, degradation, as well as improvement in the plant safety performance, can be determined. The development of risk-based performance indicators will also provide the means to trace a change in the safety measures to specific problem areas which are amenable to root cause analysis and inspection audits. In addition, systematic methods will be developed to identify specific improvement policies using the plant information system for the identified problem areas. The final product of the performance indicator project will be a methodology, and an integrated and validated set of software packages which, if properly interfaced with the logic model software of a plant, can monitor the plant performance as plant information is provided as input

  9. Regional indexes for France. Methodology

    International Nuclear Information System (INIS)

    2006-01-01

    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected. The gross data are submitted to a thorough review allowing the correction of abnormalities and the reconstitution of missing data. Each index is fashioned to take into account the economic activity in the various regions of the country as represented by each region's population. This demographic information represents a fair approximation of the weight of the regional economic activity. This document presents the calculation methodology of regional weather indexes for France. Each regional index covers an homogenous area in terms of temperature represented by the biggest city. Five reference cities are used to represent the 22 economical regions of France (Paris Orly, Lyon, Marignane, Bordeaux and Strasbourg). (J.S.)

    The performance indicator development work of the US Nuclear Regulatory Commission (NRC) interoffice task group involved several major activities that included selection of candidate indicators for a trial program, data collection and review, validation of the trial indicators, display method development, interactions with the industry, and selection of an optimum set of indicators for the program. After evaluating 27 potential indicators against certain ideal attributes, the task group selected 17 for the trial program. The pertinent data for these indicators were then collected from 50 plants at 30 sites. The validation of the indicators consisted of two primary processes: logical validity and statistical analysis. The six indicators currently in the program are scrams, safety system actuations, significant events, safety system failures, forced outage rate, and equipment forced outages per 100 critical hours. A report containing data on the six performance indicators and some supplemental information is issued on a quarterly basis. The NRC staff is also working on refinements of existing indicators and development of additional indicators as directed by the commission

  17. A Generalizable Methodology for Quantifying User Satisfaction

    Science.gov (United States)

    Huang, Te-Yuan; Chen, Kuan-Ta; Huang, Polly; Lei, Chin-Laung

    Quantifying user satisfaction is essential, because the results can help service providers deliver better services. In this work, we propose a generalizable methodology, based on survival analysis, to quantify user satisfaction in terms of session times, i. e., the length of time users stay with an application. Unlike subjective human surveys, our methodology is based solely on passive measurement, which is more cost-efficient and better able to capture subconscious reactions. Furthermore, by using session times, rather than a specific performance indicator, such as the level of distortion of voice signals, the effects of other factors like loudness and sidetone, can also be captured by the developed models. Like survival analysis, our methodology is characterized by low complexity and a simple model-developing process. The feasibility of our methodology is demonstrated through case studies of ShenZhou Online, a commercial MMORPG in Taiwan, and the most prevalent VoIP application in the world, namely Skype. Through the model development process, we can also identify the most significant performance factors and their impacts on user satisfaction and discuss how they can be exploited to improve user experience and optimize resource allocation.

  18. A methodology to enlarge narrow stability windows

    2004-07-01

    The stability window in a wellbore design is defined by the difference between fracture pressure and collapse pressure. Deep water environments typically present narrow stability windows, because rocks have low strength due to under-compaction process. Often also, horizontal wells are drilled to obtain a better development of reservoirs placed in thin layers of sandstone. In this scenario, several challenges are faced when drilling in deep water. The traditional approach for predicting instabilities is to determine collapses and fractures at borehole wall. However, the initiation of rupture does not indicate that the borehole fails to perform its function as a wellbore. Thus, a methodology in which the stability window may be enlarged is desirable. This paper presents one practical analytical methodology that consists in allowing wellbore pressures smaller than the conventional collapse pressure, i.e., based upon failure on the borehole wall. This means that a collapse region (shear failure) will be developed around the borehole wall. This collapse region is pre-defined and to estimate its size is used a failure criterion. The aforementioned methodology is implemented in a user-friendly software, which can perform analyses of stress, pore pressure, formation failure, mud weight and mud salinity design for drilling in shale formations. Simulations of a wellbore drilling in a narrow stability window environment are performed to demonstrate the improvements of using the methodology. (author)

    Diffusion of technology, environmental effects and rebound effects are the principal effects from the funding of renewable energy and energy economising. It is difficult to estimate the impact of the spread effects both prior to the measures are implemented and after the measures are carried out. Statistical methods can be used to estimate the spread effects, but they are insecure and always need to be complemented with qualitative and subjective evaluations. It is more adequate to evaluate potential spread effects from market and market data surveillance for a selection of technologies and parties. Based on this information qualitative indicators for spread effects can be constructed and used both ex ante and ex post (ml)

    Background and purpose: There is a widespread and increasing tendency to develop hospital performance indicators in the field of accreditation/certification systems and quality benchmarking. A study has been undertaken to develop a set of performance indicators for a typical radiotherapy Centre and to evaluate their ability to provide a continuous quality improvement. Materials and methods: A working group consisting of radiation oncologists, medical physicists and radiation technologists under the coordination of experts in health technology assessment has elaborated a set of general indicators able to monitor performances and the quality level of a typical radiotherapy Centre. The work has been carried out through four steps: a preliminary set of indicators was selected; data on these indicators were collected in a number of Italian radiotherapy Centres and medical physics Services; problems in collection and analysis of data were discussed; a final set of indicators was developed. Results: A final set of 13 indicators is here presented. They concern general structural and/or operational features, health physics activities and accuracy and technical complexity of the treatment. Conclusions: The indicators tested in a few Italian Centres of radiotherapy and medical physics Services are now ready to be utilized by a larger community

    Full Text Available The indicators, precisely describing the linkages between tourism and the environment, social and cultural base, are not easily available. How ever, some relevant organizations (WTO, EU, OECD, etc., institutions and experts, have been hardly working to create the indicators of sustainable tourism. Whereas the economic objectives are easily defined by the use of the traditional indicators used in national and business economics, it is very difficult to identify widely applicable environmental, social and cultural indicators. In order to stimulate and alleviate the process of sustainable tourism development, EU created the list of comparative indicators of sustainable tourism. In preparing this list, special attention is paid to identification of valid indicators of real tourism impacts on the social and cultural environment (the entire set of traditions, customs, history, hospitality and culture that characterize a given area, that is a very complex task. Assuming the fact that the related indicators have been analyzed in many European countries, this paper is focused on applying the related indicators in research of tourism development in villages of the Kosjerić community. .

    Full Text Available This paper deals with the evaluation of selected available indicators of living standards, divided into three groups, namely economic, environmental, and social. We have selected six countries of the European Union for analysis: Bulgaria, the Czech Republic, Hungary, Luxembourg, France, and Great Britain. The aim of this paper is to evaluate indicators measuring living standards and suggest the most important factors which should be included in the final measurement. We have tried to determine what factors influence each indicator and what factors affect living standards. We have chosen regression analysis as our main method. From the study of factors, we can deduce their impact on living standards, and thus the value of indicators of living standards. Indicators with a high degree of reliability include the following factors: size and density of population, health care and spending on education. Emissions of carbon dioxide in the atmosphere also have a certain lower degree of reliability.

    The purpose of this document is to show a method for the fast recalculation of the PSA. To avoid the information loose, it is necessary to simplify the PSA models, or at least reorganize them. The method, introduced in this document, require that preparation, so we try to show, how to do that. This document is an introduction. This is the starting point of the work related to the development of the risk indicators. In the future, with the application of this method, we are going to show an everyday use of the PSA results to produce the indicators of the core damage risk. There are two different indicators of the plant safety performance, related to the core damage risk. The first is the core damage frequency indicator (CDFI), and the second is the core damage probability indicator (CDPI). Of course, we cannot describe all of the possible ways to use these indicators, rather we will try to introduce the requirements to establish such an indicator system and the calculation process

We have to consider not only heating but all service energies related to the human comfort in the building, such as cooling, ventilation, lighting as well. The complexity coming from this embracing approach is not to be underestimated. It is less and less possible to realted simple characteristic performance indicators of building envelopes (such as the U-value) to the overall energy performance. On the one hand much more paramters (e.g. light transmittance) come into the picture we have to assess the product quality in a multidimensional world. Secondly buildings more and more have to work on a narrow optimum: For an old, badly insulated building all solar gains are useful for a high-performance building with very good insulation and heat recovery systems in the ventilation overheating becomes more likely. Thus we have to control the solar gains, and sometimes we need high gains, sometimes low ones. And thirdly we see that the technology within the building and the user patterns and interactions as well influence the performance of a building envelope. The aim of this project within IEA Task27 was to improve our knowledge on the complex situation and also to give a principal approach how to assess the performance of the building envelope. The participants have contributed to this aim not pretending that we have reached the end. (au)

  15. Screening Risk Evaluation methodology

    International Nuclear Information System (INIS)

    Hopper, K.M.

    1994-01-01

    The Screening Risk Evaluation (SRE) Guidance document is a set of guidelines provided for the uniform implementation of SREs performed on D ampersand D facilities. These guidelines are designed specifically for the completion of the second (semi-quantitative screening) phase of the D ampersand D Risk-Based Process. The SRE Guidance produces screening risk scores reflecting levels of risk through the use of risk ranking indices. Five types of possible risk are calculated from the SRE: current releases, worker exposures, future releases, physical hazards, and criticality. The Current Release Index (CRI) calculates the risk to human health and the environment from ongoing or probable releases within a one year time period. The Worker Exposure Index (WEI) calculates the risk to workers, occupants, and visitors in D ampersand D facilities of contaminant exposure. The Future Release Index (FRI) calculates the risk of future releases of contaminants, after one year, to human health and the environment. The Physical Hazards Index (PHI) calculates the risk-to human health due to factors other than that of contaminants. The index of Criticality is approached as a modifying factor to the entire SRE, due to the fact that criticality issues are strictly regulated under DOE. Screening risk results will be tabulated in matrix form and Total Risk will be calculated (weighted equation) to produce a score on which to base early action recommendations. Other recommendations from the screening risk scores will be made based either on individual index scores or from reweighted Total Risk calculations. All recommendations based on the SRE will be made based on a combination of screening risk scores, decision drivers, and other considerations, determined on a project by project basis. The SRE is the first and most important step in the overall D ampersand D project level decision making process

    1999-06-01

    This report proposes and describes in detail several air quality indicators that may be used to describe population exposure. The suggested indicators account for temporal and spatial patterns of pollution and movements of individuals between different micro-environments. The Air Quality Indicator /AQI) should represent both the spatial and temporal aspects of pollution exposure that may have important effects on health. Two indicators are needed, the Population Air Quality Indicator and the Individual Air Quality Indicator. Mean concentrations, 98th percentile and maximum values are the traditional indicators for estimating exposure. the temporal variability of PM-10 and NO 2 , however, is here described by means of: 1) The rate of change of pollution as the difference between two consecutive hourly values and of 2) episodes, described in terms of number, duration and winter episode period, maximum concentration in the episode and integrated episode exposure (episode AOT50/100). The spatial variation of AQIs can be described in several ways, e.g.: 1) Concentrations in neighbouring grid squares can be compared as an indication of spatial variation and 2) point estimates can be compared to grid values for a description of variation within a grid. Both methods are presented here. A test of the representativity of static point estimates for pollution exposure is to compare them to an estimate of air pollution exposure accounting for movements between different locations, obtained using diaries. The ultimate aim of AQIs is to describe the population exposure to ambient pollution. This is done by estimating the number of people exposed using different characteristics of AQIs. The data used to describe these indicators originates from dispersion modelling of short-term air pollution concentrations in Oslo. Two series of data are used. One represents hour-for hour concentrations in the 1 km 2 grid system covering the city of Oslo, winter 1994/95, calculated by the grid

    The concept of energy security is widely used, yet there is no consensus on its precise interpretation. In this research, we have provided an overview of available indicators for long-term security of supply (SOS). We distinguished four dimensions of energy security that relate to the availability, accessibility, affordability and acceptability of energy and classified indicators for energy security according to this taxonomy. There is no one ideal indicator, as the notion of energy security is highly context dependent. Rather, applying multiple indicators leads to a broader understanding. Incorporating these indicators in model-based scenario analysis showed accelerated depletion of currently known fossil resources due to increasing global demand. Coupled with increasing spatial discrepancy between consumption and production, international trade in energy carriers is projected to have increased by 142% in 2050 compared to 2008. Oil production is projected to become increasingly concentrated in a few countries up to 2030, after which production from other regions diversifies the market. Under stringent climate policies, this diversification may not occur due to reduced demand for oil. Possible benefits of climate policy include increased fuel diversity and slower depletion of fossil resources. (author)

    Proliferation resistance is one of the requirement to be met in GEN IV and INPRO for next generation nuclear energy system. Internationally, the evaluation methodology on PR had been already initiated from 1980, but the systematic development was started at 2000s. In Korea, for the export of nuclear energy system and the increase of international credibility and transparence of domestic nuclear system and fuel cycle development, the independent development of PR evaluation methodology was started in 2007 as a nuclear long term R and D project and the development is being performed for the model of PR evaluation methodology. In 1st year, comparative study of GEN-IV/INPRO, PR indicator development, quantification of indicator and evaluation model development, analysis of technology system and international technology development trend had been performed. In 2nd year, feasibility study of indicator, allowable limit of indicator, review of technical requirement of indicator were done. The results of PR evaluation must be applied in the beginning of conceptual design of nuclear system. Through the technology development of PR evaluation methodology, the methodology will be applied in the regulatory requirement for authorization and permission to be developed

  4. Minimum risk trigger indices

    1979-01-01

    A viable safeguards system includes among other things the development and use of indices which trigger various courses of action. The usual limit of error calculation provides such an index. The classical approach is one of constructing tests which, under certain assumptions, make the likelihood of a false alarm small. Of concern also is the test's failure to indicate a loss (diversion) when in fact one has occurred. Since false alarms are usually costly and losses both costly and of extreme strategic sinificance, there remains the task of balancing the probability of false alarm and its consequences against the probability of undetected loss and its consequences. The application of other than classical hypothesis testing procedures are considered in this paper. Using various consequence models, trigger indices are derived which have certain optimum properties. Application of the techniques would enhance the material control function

MATERIAL AND METHODS: A sub-sample of 6 021 fasting adult participants was randomly selected from the total fasting participants (n=39 425. We compared diverse socio-demographic, anthropometric and health parameters between this sub-sample and the rest of the participants. RESULTS: No differences were found in sociodemographics characteristics, except age, between the sub-sample and from the rest of the fasting adults. In addition no difference were found between prevalences of overweight and obesity, central obesity, and previously diagnosed high blood pressure, T2D or hypertrigliceridemia. CONCLUSIONS: The randomly selected sub-sample was not essentially different from the rest of the fasting subjects. Thus, no bias is expected in the interpretation of cardiovascular risk indicators derived from these data.OBJETIVO: Describir: a los métodos usados para definir Diabetes tipo 2 (T2D, y otros indicadores de riesgo cardiovascular en la submuestra de la Encuesta Nacional de Salud y Nutrición 2006 (ENSANUT 2006 y b comparar en características sociodemográficas, antropométricas y otros determinantes de salud a los participantes de la submuestra con los no seleccionados.

    A temperature indicating device comprises a plurality of planar elements some undergoing a reversible change in appearance at a given temperature the remainder undergoing an irreversible change in appearance at a given temperature. The device is useful in indicating the temperature which an object has achieved as well as its actual temperature. The reversible change is produced by liquid crystal devices. The irreversible change is produced by an absorbent surface carrying substances e.g. waxes which melt at predetermined temperatures and are absorbed by the surface; alternatively paints may be used. The device is used for monitoring processes of encapsulation of radio active waste. (author)

    Today selective coronary angiography, introduced by Sones in 1957, is used as clinical routine for diagnosing morphological changes in the coronary arteries. Hitherto, more recent techniques such as digital subtraction angiography cannot provide comparable information. Strict criteria for its indication depending on possible therapeutic consequences, have to be applied, although the risk is low with a letality of 0.01 to 0.05 percent. Radionuclear investigations can be used as additional tool in selected cases. The careful indication for coronary angiography usually implies the possible need for coronary bypass graft surgery of balloon angioplasty. (orig./MG) [de

  10. A dose to curie conversion methodology

    International Nuclear Information System (INIS)

    Stowe, P.A.

    1987-01-01

    Development of the computer code RadCAT (Radioactive waste Classification And Tracking) has led to the development of a simple dose rate to curie content conversion methodology for containers with internally distributed radioactive material. It was determined early on that, if possible, the computerized dose rate to curie evaluation model employed in RadCAT should yield the same results as the hand method utilized and specified in plant procedures. A review of current industry practices indicated two distinct types of computational methodologies are presently in use. The most common methods are computer based calculations utilizing complex mathematical models specifically established for various containers geometries. This type of evaluation is tedious, however, and does not lend itself to repetition by hand. The second method of evaluation, therefore, is simplified expressions that sacrifice accuracy for ease of computation, and generally over estimate container curie content. To meet the aforementioned criterion current computer based models were deemed unacceptably complex and hand computational methods to be too inaccurate for serious consideration. The contact dose rate/curie content analysis methodology presented herein provides an equation that is easy to use in hand calculations yet provides accuracy equivalent to other computer based computations

    The substantial burden of cancer and diabetes and the association between the two conditions has been a motivation for researchers to look for targeted strategies that can simultaneously affect both diseases and reduce their overlapping burden. In the absence of randomized clinical trials, researchers have taken advantage of the availability and richness of administrative databases and electronic medical records to investigate the effects of drugs on cancer risk among diabetic individuals. The majority of these studies suggest that metformin could potentially reduce cancer risk. However, the validity of this purported reduction in cancer risk is limited by several methodological flaws either in the study design or in the analysis. Whether metformin use decreases cancer risk relies heavily on the availability of valid data sources with complete information on confounders, accurate assessment of drug use, appropriate study design, and robust analytical techniques. The majority of the observational studies assessing the association between metformin and cancer risk suffer from methodological shortcomings and efforts to address these issues have been incomplete. Future investigations on the association between metformin and cancer risk should clearly address the methodological issues due to confounding by indication, prevalent user bias, and time-related biases. Although the proposed strategies do not guarantee a bias-free estimate for the association between metformin and cancer, they will reduce synthesis of and reporting of erroneous results.

    2015-01-01

    Full Text Available Agriculture and Climate Change: Challenges and Solutions. According to the latest report from the Intergovernmental Panel on Climate Change (IPCC, climate change is already having a significant impact on agriculture. Several models highlight the increasingly negative effects of increased temperatures on crop yields and livestock farming in developing countries. These impacts can be caused by negative physiological effects for plants and animals, which result from higher temperatures or the proliferation of pests and diseases caused by the latter. The increased number of extreme weather events, especially floods, and changing precipitation patterns are linked to climate changes. These factors dramatically affect the crop production potential of agricultural land. Populations in the developing world, which are already vulnerable and exposed to food insecurity, are the most seriously affected. In many countries in the southern hemisphere, agriculture actually represents the main source of income for a major proportion of the active population. Combined with increased demographic pressure, climate changes therefore help to exacerbate the pressure on global food systems. In addition, it should be noted that agriculture also plays a key role in the reduction of greenhouse gas emissions and is therefore at the heart of a variety of complex issues. In light of these facts, it is essential that we make every effort to identify solutions, aimed at adapting to climate changes and alleviating the contribution of certain agricultural practices to the latter, in order to respond to all the challenges that they create. This involves reinforcing research initiatives aimed at understanding and quantifying the problems, while identifying steps that need to be taken in order to limit these problems. It also involves lobbying for appropriate policies to be put into place, based on the results of this research. Last but not least, it involves developing field projects in order to identify and promote appropriate farming practices and create conditions that will help them become more widespread. With this in mind, we welcome the Montpellier Declaration initiative (http://csa2015.cirad.fr, which was developed at the Third Global Science Conference on Climate Smart Agriculture (Climate Smart Agriculture 2015 that was held in this city on 16-18 March 2015. At this event, over 600 research scientists and 150 stakeholders/policy makers - from 75 countries and 5 continents – confirmed that climate smart agriculture has become a benchmark, which creates synergies and may lead to innovative and global solutions at local, regional and international level. The participants also confirmed that climate smart solutions exist and could become a reality if the conditions and public policies lend themselves to these solutions. We encourage all readers of Tropicultura to learn more about the work completed at this conference, in order to understand issues linked to climate change and identify sources of inspiration, so that we can overcome the constraints that it imposes.

  16. Indications for fetal magnetic resonance imaging (MRI)

    International Nuclear Information System (INIS)

    Prayer, D.

    2006-01-01

    Indications to perform fetal magnetic resonance imaging (MRI) are composed of common ones related to methodological problems of ultrasound (US) assessment (such as for instance hydramnios) and special ones. The latter are related to MR capability of high-resolution soft tissue contrast and an extended field of view that allows visualization of the whole fetus, even in later stages of pregnancy. The most important indications include confirmation of US findings, work-up of malformations with respect to individual prognosis and genetic background, differentiation between acquired conditions and malformations, visualization of pathologies that have to be treated surgically immediately after birth, and morphological changes of the placenta.

    We prove that for a Hamiltonian system on a cotangent bundle that is Liouville-integrable and has monodromy the vector of Maslov indices is an eigenvector of the monodromy matrix with eigenvalue 1. As a corollary, the resulting restrictions on the monodromy matrix are derived. (letter to the editor)

    Lichens are very responsive to environmental stressors in forests, including changes in forest structure, air quality, and climate. Each lichen species on a plot is an indicator of how lichen communities respond to ecological conditions. Individual lichen species occur erratically and even common species are often absent from plots with suitable habitat. The combined...

  20. Managerial Methodology in Public Institutions

    Directory of Open Access Journals (Sweden)

    Ion VERBONCU

    2010-10-01

    Full Text Available One of the most important ways of making public institutions more efficient is by applying managerial methodology, embodied in the promotion of management tools, modern and sophisticated methodologies, as well as operation of designing/redesigning and maintenance of the management process and its components. Their implementation abides the imprint of constructive and functional particularities of public institutions, decentralized and devolved, and, of course, the managers’ expertise of these organizations. Managerial methodology is addressed through three important instruments diagnosis, management by objectives and scoreboard. Its presence in the performance management process should be mandatory, given the favorable influence on the management and economic performance and the degree of scholastic approach of the managers’ performance.

  1. Blanket safety by GEMSAFE methodology

    International Nuclear Information System (INIS)

    Sawada, Tetsuo; Saito, Masaki

    2001-01-01

    General Methodology of Safety Analysis and Evaluation for Fusion Energy Systems (GEMSAFE) has been applied to a number of fusion system designs, such as R-tokamak, Fusion Experimental Reactor (FER), and the International Thermonuclear Experimental Reactor (ITER) designs in the both stages of Conceptual Design Activities (CDA) and Engineering Design Activities (EDA). Though the major objective of GEMSAFE is to reasonably select design basis events (DBEs) it is also useful to elucidate related safety functions as well as requirements to ensure its safety. In this paper, we apply the methodology to fusion systems with future tritium breeding blankets and make clear which points of the system should be of concern from safety ensuring point of view. In this context, we have obtained five DBEs that are related to the blanket system. We have also clarified the safety functions required to prevent accident propagations initiated by those blanket-specific DBEs. The outline of the methodology is also reviewed. (author)

  2. The NLC Software Requirements Methodology

    Energy Technology Data Exchange (ETDEWEB)

    Shoaee, Hamid

    2002-08-20

    We describe the software requirements and development methodology developed for the NLC control system. Given the longevity of that project, and the likely geographical distribution of the collaborating engineers, the planned requirements management process is somewhat more formal than the norm in high energy physics projects. The short term goals of the requirements process are to accurately estimate costs, to decompose the problem, and to determine likely technologies. The long term goal is to enable a smooth transition from high level functional requirements to specific subsystem and component requirements for individual programmers, and to support distributed development. The methodology covers both ends of that life cycle. It covers both the analytical and documentary tools for software engineering, and project management support. This paper introduces the methodology, which is fully described in [1].

    Carless, J.; Dow, B.; Farivari, R.; O'Connor, J.; Fox, T.; Tunstall, D.; Mentzingen, M.

    1992-01-01

    The clear value of economic data and analysis to decisionmakers has motivated them to mandate the creation of extensive global economic data sets. This chapter contains a set of these basic economic data, which provides the context for understanding the causes and the consequences of many of the decisions that affect the world's resources. Many traditional economic indicators fail to account for the depletion or deterioration of natural resources, the long-term consequences of such depletion, the equitable distribution of income within a country, or the sustainability of current economic practices. The type of measurement shown here, however, is still useful in showing the great differences between the wealthiest and the poorest countries. Tables are given on the following: Gross national product and official development assistance 1969-89; External debt indicators 1979-89; Central government expenditures; and World commodity indexes and prices 1975-89

  6. Trochleoplasty: Indications and Technique.

    Nolan, John E; Schottel, Patrick C; Endres, Nathan K

    2018-05-09

    Trochlear dysplasia is a well-described risk factor for patellar instability. Trochleoplasty has emerged as a procedure within the surgical armamentarium for patellar instability, yet its role is unclear. A variety of trochleoplasty procedures have emerged. The purpose of this review is to clarify indications for trochleoplasty, outline the technical steps involved in performing common trochleoplasties and report the published outcomes and potential complications of these procedures. Patellar instability with severe trochlear dysplasia is the main indication for trochleoplasty. Three types of trochleoplasty have emerged: (1) lateral facet elevation; (2) sulcus deepening; and (3) recession wedge. Deepening and recession wedge trochleoplasties are the most commonly performed. Trochleoplasty is a surgical option for addressing patellar instability in patients with severe trochlear dysplasia. Deepening and recession wedge trochleoplasties that address Dejour B and D dysplastic trochleas are the most studied, with both short- and midterm outcomes reported. Long-term outcomes are lacking and comparative studies are needed.

  7. Lichens as bio indicators

    International Nuclear Information System (INIS)

    2003-01-01

    This publication discusses the use of lichens as biological indicators. Perennial growth, long life, efficient take-up of mineral nutrients from air and rain and small loss of nutrition are properties that make lichens suitable as biological indicators. In surveys and monitoring, species diversity and coverage by organisms that live as epiphytes on tree trunks have been the most commonly used parameters. A decline in the occurrence of this type of lichen is often related to the content of sulphur compounds in the air and it has been demonstrated that many species are sensitive to sulphur dioxide. It is also known that the growth of many types of lichens increases with a moderate increase in available nitrogen. In South Norway, pollution sensitive species such as Bryoria spp. have advanced strongly, which is probably due to less sulphur in the rain and a higher content of nutrition in the form of nitrate and ammonium

    While all parties involved in nuclear plant regulation endeavor to make decisions which optimize the considerations of plant safety and financial impacts, these decisions are generally made without the benefit of a systematic and rigorous approach to the questions confronting the decision makers. A Design Decision Methodology has been developed which provides such a systematic approach. By employing this methodology, which makes use of currently accepted probabilistic risk assessment techniques and cost estimation, informed decisions may be made against a background of comparisons between the relative levels of safety and costs associated with various design alternatives

    2017-10-01

    City sustainable development indicators and indices have become a hot issue in academic research and practical application, alongside the high-speed worldwide urbanization and driven by the actual managing demand. This article is aimed at a clear understanding of the progress in relevant research and practice. This is done by collecting common indicators and indices for city sustainable development and making comparison of the assessment process and contents, so as to find out main obstacles for the development of this research field and explore the direction for efforts to be made next step. The article divides these indicators and indices into two categories: ① indicators serving as single index which can provide an explicit description on the relationship between economic activities and environmental carrying capacity, but have a narrow scope of assessment and use complicated methods to collect and calculate data; ② indices based on indicator systems which can represent multiple processes, could reflect the view of strong sustainability and are easy to use, but can hardly depict the responding relationship between social, environmental and economic changes for city sustainable development or assure the scientific rigor of weight setting. Practices on indicators and indices for city sustainable development was summarized, and its problems were reviewed with China being representative of transitioning countries. According to the review, great progress has been achieved in the research and practice of indicators and indices for city sustainable development, but consistency of theories, rationality of indicators and scientific rigor of methodology are to be improved significantly.

    2011-07-01

    The work of the inter-ministerial group 'Impacts of Climate Change, Adaptation and Associated Costs for France', which met between March 2007 and October 2009, led to a sector-based assessment of all climate change related impacts and of associated adaptation measures. The aim was to obtain quantified elements that could underpin public policy decision-making and especially development of the National Adaptation Plan. While the sectoral analyses focused on quantifying the costs of adaptation, the approach of the 'Territories' group, co-steered by the Datar (regional development delegation) and Ademe (agency for energy management and environment), addressed the subject of interactions between players and activities, both spatial (sharing of resources between different uses, etc.) and temporal (transition from one situation to another, etc.) and the corresponding means for adjustment. It was in this context that the SOeS proposed a methodology for diagnosis of the socio-economic vulnerability of a given sub-national territory in the face of climate change. This document provides a broad-brush outline of the accompanying guidelines developed by Sogreah Consultants SAS for use by local players. A three step approach is followed to draw up the vulnerability profile of a territory: 1 - characterising the territory by the identification of the priority activities and physical features; 2 - using the analysis tools to produce a matrix of indices of vulnerability to climate change per hazard; 3 - drawing up an initial vulnerability profile by bringing together the information from the matrix and that from feedback, either by activity or group of activities, or by environment, depending on aims. The profile leads to identification of the important issues as well as allowing identification of potential impacts to be studied in more depth. Guidelines were tested in three pilot territories facing different climate change issues: Wateringues, in the Nord

  19. Systematic review of communication partner training in aphasia: methodological quality.

    Cherney, Leora R; Simmons-Mackie, Nina; Raymer, Anastasia; Armstrong, Elizabeth; Holland, Audrey

    2013-10-01

    Twenty-three studies identified from a previous systematic review examining the effects of communication partner training on persons with aphasia and their communication partners were evaluated for methodological quality. Two reviewers rated the studies on defined methodological quality criteria relevant to each study design. There were 11 group studies, seven single-subject participant design studies, and five qualitative studies. Quality scores were derived for each study. The mean inter-rater reliability of scores for each study design ranged from 85-93%, with Cohen's Kappa indicating substantial agreement between raters. Methodological quality of research on communication partner training in aphasia was highly varied. Overall, group studies employed the least rigorous methodology as compared to single subject and qualitative research. Only two of 11 group studies complied with more than half of the quality criteria. No group studies reported therapist blinding and only one group study reported participant blinding. Across all types of studies, the criterion of treatment fidelity was most commonly omitted. Failure to explicitly report certain methodological quality criteria may account for low ratings. Using methodological rating scales specific to the type of study design may help improve the methodological quality of aphasia treatment studies, including those on communication partner training.

  4. IMSF: Infinite Methodology Set Framework

    Science.gov (United States)

    Ota, Martin; Jelínek, Ivan

    Software development is usually an integration task in enterprise environment - few software applications work autonomously now. It is usually a collaboration of heterogeneous and unstable teams. One serious problem is lack of resources, a popular result being outsourcing, ‘body shopping’, and indirectly team and team member fluctuation. Outsourced sub-deliveries easily become black boxes with no clear development method used, which has a negative impact on supportability. Such environments then often face the problems of quality assurance and enterprise know-how management. The used methodology is one of the key factors. Each methodology was created as a generalization of a number of solved projects, and each methodology is thus more or less connected with a set of task types. When the task type is not suitable, it causes problems that usually result in an undocumented ad-hoc solution. This was the motivation behind formalizing a simple process for collaborative software engineering. Infinite Methodology Set Framework (IMSF) defines the ICT business process of adaptive use of methods for classified types of tasks. The article introduces IMSF and briefly comments its meta-model.

    1999-01-01

    A methodology for designing Unattended Monitoring Systems starting at a systems level has been developed at Sandia National Laboratories. This proven methodology provides a template that describes the process for selecting and applying appropriate technologies to meet unattended system requirements, as well as providing a framework for development of both training courses and workshops associated with unattended monitoring. The design and implementation of unattended monitoring systems is generally intended to respond to some form of policy based requirements resulting from international agreements or domestic regulations. Once the monitoring requirements are established, a review of the associated process and its related facilities enables identification of strategic monitoring locations and development of a conceptual system design. The detailed design effort results in the definition of detection components as well as the supporting communications network and data management scheme. The data analyses then enables a coherent display of the knowledge generated during the monitoring effort. The resultant knowledge is then compared to the original system objectives to ensure that the design adequately addresses the fundamental principles stated in the policy agreements. Implementation of this design methodology will ensure that comprehensive unattended monitoring system designs provide appropriate answers to those critical questions imposed by specific agreements or regulations. This paper describes the main features of the methodology and discusses how it can be applied in real world situations

  7. A methodology for string resolution

    International Nuclear Information System (INIS)

    Karonis, N.T.

    1992-11-01

    In this paper we present a methodology, not a tool. We present this methodology with the intent that it be adopted, on a case by case basis, by each of the existing tools in EPICS. In presenting this methodology, we describe each of its two components in detail and conclude with an example depicting how the methodology can be used across a pair of tools. The task of any control system is to provide access to the various components of the machine being controlled, for example, the Advanced Photon Source (APS). By access, we mean the ability to monitor the machine's status (reading) as well as the ability to explicitly change its status (writing). The Experimental Physics and Industrial Control System (EPICS) is a set of tools, designed to act in concert, that allows one to construct a control system. EPICS provides the ability to construct a control system that allows reading and writing access to the machine. It does this through the notion of databases. Each of the components of the APS that is accessed by the control system is represented in EPICS by a set of named database records. Once this abstraction is made, from physical device to named database records, the process of monitoring and changing the state of that device becomes the simple process of reading and writing information from and to its associated named records

    2016-07-01

    Full Text Available The article deals with the investigation of theoretical and methodological principles of situational analysis. The necessity of situational analysis is proved in modern conditions. The notion “situational analysis” is determined. We have concluded that situational analysis is a continuous system study which purpose is to identify dangerous situation signs, to evaluate comprehensively such signs influenced by a system of objective and subjective factors, to search for motivated targeted actions used to eliminate adverse effects of the exposure of the system to the situation now and in the future and to develop the managerial actions needed to bring the system back to norm. It is developed a methodological approach to the situational analysis, its goal is substantiated, proved the expediency of diagnostic, evaluative and searching functions in the process of situational analysis. The basic methodological elements of the situational analysis are grounded. The substantiation of the principal methodological elements of system analysis will enable the analyst to develop adaptive methods able to take into account the peculiar features of a unique object which is a situation that has emerged in a complex system, to diagnose such situation and subject it to system and in-depth analysis, to identify risks opportunities, to make timely management decisions as required by a particular period.

    The objective of this thesis was to contribute to a better understanding of the impact of the atmospheric pollutions on lichens in experimental conditions of field (Lorraine region, France). Techniques of sampling areas analysis for epiphytic lichens were little developed in bio-indication. Without a precise method and a solid validation of the choices of the surface of sampling, survey analysis continue to be subjective and comparative studies and hypotheses testing are rough. To examine this problem, we tested an operational technique of sampling and spatial analysis, based on digitized and geo-referenced data, which makes more objective the lichen covering and frequency assessment. We present a simple example to demonstrate how our investigations will allow to do the link between survey and air quality diagnosis, with perspectives on i) stratified random sampling techniques of lichen communities based on the image interpretation, ii) multi-scale sampling techniques to estimate the efficiency of the sampling grid classically used in bio-monitoring and iii) GIS (Geographical Information Systems) and geostatistical techniques to study floristic and ecological variations at every sampling point. The transplantation is a field technique used for the study air pollution effects and chemical elements accumulation on the lichen symbiosis. Precipitation is known to play an important role in the uptake and release of chemical elements by lichen thalli, but few information was available on their roles in the lichen resistance exposed to photo-oxidizing pollutants. We used this technique to study the effects of gas pollutants and airborne chemical elements on the lichen physiology exposed or not at precipitation. To analyze these interactions, the lichen Hypogymnia physodes (L.) Nyl. was transplanted to 5 locations of the Moselle valley with different levels of air pollution for 14, 34 and 68 days (summer 2001). In each of these sites, 6 transplantation designs, covered or

    Highlights: ► AESPI shows a country’s (or province’s) energy security status. ► AESPI considers social, economic and environmental aspects using 25 indicators. ► AESPI shows the impact of the trend of energy policies/measures. ► AESPI could be a tool for monitoring and evaluating the impact of energy policies. -- Abstract: An “Aggregated Energy Security Performance Indicator (AESPI)” has been developed by considering 25 individual indicators representing social, economy and environmental dimensions. The principle used, data required and the methodology for the development of AESPI have been detailed. AESPI requires time series data for its development and its value ranges from 0 to 10. The characteristics of AESPI have been compared with the existing indicators in terms of methodology, data requirements, analysis possible and the applications. The advantages of AESPI is that it not only assists in knowing the past energy security status of a country, but also helps in assessing the future status considering the energy policies and plans of the country, thus enabling the monitoring of the impacts of the policies.

  16. SG39 Deliverables. Summary of Methodology

    For providing useful and physical feedback to nuclear data evaluators from cross section adjustment results, it is necessary to assess the reliability of the adjustment results. For instance, the adjustment results may include so-called 'compensation effects' which cause fictitious alterations of adjusted cross-sections by the cancellation of two or more reactions of cross sections. Typical compensation effects are possible in the following reactions: - Pu-239 fission spectrum and inelastic in general: Equivalent effect through neutron spectrum changes - Capture and (n,2n) for irradiation experiments: Same impact of disappearing the associated isotope - Capture and fission for spectral indices: e.g. U-238 capture (C28) and Pu-239 fission (F49) for C28/F49; Compensation between numerator and denominator - Many reactions for criticalities: Capture, fission, ν, χ, inelastic, elastic,... In addition, useless and unphysical systematic effects may occur in the cross section adjustments. To avoid the compensation effects and to point out systematic effects, several criteria with parameters/indices are recommended to use. This document summarizes the methodology with the definitions of the parameters/indices. Although a lot of parameters/indices are reported in the intermediate report of Subgroup 33, many institutions use their own different nomenclature to describe the parameters/indices about the cross section adjustment. Therefore, Subgroup 39 proposes a common nomenclature for convenience. (author)

    Protecting sensitive items from undetected tampering in an unattended environment is crucial to the success of non-proliferation efforts relying on the verification of critical activities. Tamper Indicating Packaging (TIP) technologies are applied to containers, packages, and equipment that require an indication of a tamper attempt. Examples include: the transportation and storage of nuclear material, the operation and shipment of surveillance equipment and monitoring sensors, and the retail storage of medicine and food products. The spectrum of adversarial tampering ranges from attempted concealment of a pin-hole sized penetration to the complete container replacement, which would involve counterfeiting efforts of various degrees. Sandia National Laboratories (SNL) has developed a technology base for advanced TIP materials, sensors, designs, and processes which can be adapted to various future monitoring systems. The purpose of this technology base is to investigate potential new technologies, and to perform basic research of advanced technologies. This paper will describe the theory of TIP technologies and recent investigations of TIP technologies at SNL

    2001-01-01

    A new fuzzy-logic-based methodology for on-line signal trend identification is introduced. The methodology may be used for detecting the onset of nuclear power plant (NPP) transients at the earliest possible time and could be of great benefit to diagnostic, maintenance, and performance-monitoring programs. Although signal trend identification is complicated by the presence of noise, fuzzy methods can help capture important features of on-line signals, integrate the information included in these features, and classify incoming NPP signals into increasing, decreasing, and steady-state trend categories. A computer program named PROTREN is developed and tested for the purpose of verifying this methodology using NPP and simulation data. The results indicate that the new fuzzy-logic-based methodology is capable of detecting transients accurately, it identifies trends reliably and does not misinterpret a steady-state signal as a transient one

    Environmental indicators are tools utilized for measuring the industrial environmental performance and are globally used to provide the company and other stakeholders with information concerning its effectiveness and sustainability. Furthermore, the environmental indicators are an important methodological tool used for monitoring the effectiveness of Environmental Management System goals, as well as its compliance with the established environmental policies. Currently, major companies have reported their environmental indicators based on specialized guides, such as the CDP (Carbon Disclosure Project) and the GRI (Global Reporting Initiative), enumerating the most important indicators for the company activities. However, the GRI as other bibliographies of this subject does not include specific indicators for the nuclear area, leaving a significant gap to be considered for the measurement of environmental performance of this industry. Therefore, it becomes relevant to raise the following questions. May the nuclear sector use the same indicators of the non-nuclear industry? Are these indicators effective in demonstrating environmental commitment? In this work, a discussion of the indicators for the nuclear area and the CTMSP will take place. (author)

    2003-07-08

    The present invention provides an apparatus and method whereby the reliability and tamper-resistance of tamper indicators can be improved. A flexible connector may be routed through a latch for an enclosure such as a door or container, and the free ends of the flexible connector may be passed through a first locking member and firmly attached to an insert through the use of one or more attachment members such as set screws. A second locking member may then be assembled in interlocking relation with the first locking member to form an interlocked assembly around the insert. The insert may have one or more sharp projections extending toward the first or second locking member so that any compressive force applied in an attempt to disassemble the interlocked assembly results in permanent, visible damage to the first or second locking member.

    1964-02-24

    A plurality of magnetically operated switches are spaced equally in the hollow tube of a control rod actuating mechanism. One side of each switch is connected, via a low resistance, to a corresponding tap of a low resistance voltage divider network consisting of an equivalent number of low resistance sections with the opposite side of each switch connected to a common conducting wire A. To both ends of the voltage dividing network are connected, respectively, conducting wires B and C. Wires A, B, and C are further coupled to a fuel rod position indicator comprising a voltmeter and power source external to the control rod actuating member. The control rod actuating member is adapted to slide in the hollow tube so that switches passing a position facing a magnet secured to the lower end of the actuating member are rendered closed. Hence, the position of the control rod may be read by reading the voltage off the meter.

  9. Lichens as pollution indicators

    Energy Technology Data Exchange (ETDEWEB)

    Rose, F

    1970-01-01

    Although lichens are generally considered to be of little use to man, their sensitivity to air pollution makes them good biological indicators. The author describes how this feature can help to establish relative degrees of air pollution. He notes areas where lichens are reduced in number and vigor, and some in which they have disappeared altogether. He challenges the idea that dryness is responsible, since they have also disappeared from damp woodland areas. Experimental work supports the view that sulfur dioxide is the major factor rather than smoke, although there is no definitive proof. Lichen damage correlates best with mean winter levels of air pollution by SO/sub 2/. 16 references, 1 figure.

  11. Flammability Indices for Refrigerants

    Science.gov (United States)

    Kataoka, Osami

    This paper introduces a new index to classify flammable refrigerants. A question on flammability indices that ASHRAE employs arose from combustion test results of R152a and ammonia. Conventional methods of not only ASHRAE but also ISO and Japanese High-pressure gas safety law to classify the flammability of refrigerants are evaluated to show why these methods conflict with the test results. The key finding of this paper is that the ratio of stoichiometric concentration to LFL concentration (R factor) represents the test results most precisely. In addition, it has excellent correlation with other flammability parameters such as flame speed and pressure rise coefficient. Classification according to this index gives reasonable flammability order of substances including ammonia, R152a and carbon monoxide. Theoretical background why this index gives good correlation is also discussed as well as the insufficient part of this method.

    Full Text Available Osteoporosis is a condition of impaired bone strength that results in an increased risk of fracture. The current and most popular pharmacological options for the treatment of osteoporosis include antiresorptive therapy, in particular, oral bisphosphonates (alendronate, risedronate, ibandronate. Anabolic agents like teriparatide have widened our therapeutic options. They act by directly stimulating bone formation and improving bone mass quantity and quality. Two forms of recombinant human parathyroid hormone (PTH are available : full-length PTH (PTH 1-84; approved in the EU only and the 1-34 N-terminal active fragment of PTH (teriparatide, US FDA approved. This review aims to discuss the benefits of teriparatide beyond the currently licensed indications like fracture healing, dental stability, osteonecrosis of jaw, hypoparathyroidism, and hypocalcemia.

    Full Text Available Congenital heart diseases are encountered in 0.8% of live births and are among the most frequently diagnosed malformations. At least half of these anomalies end up with death or require surgical interventions and are responsible for 30% of the perinatal mortality. Fetal echocardiography is the sum of knowledge, skill and orientation rather than knowing the embryologic details of the fetal heart. The purpose of fetal echocardiography is to document the presence of normal fetal cardiac anatomy and rhythm in high risk group and to define the anomaly and arrhythmia if present. A certain sequence should be followed during the evaluation of fetal heart. Sequential segmental analysis (SSA and basic definition terminology made it possible to determine a lot of complex cardiac anomalies during prenatal period. By the end of 1970’s, Shinebourne started using sequential segmental analysis for fetal cardiac evaluation and today, prenatal diagnosis of congenital heart disease is possible without any confusion. In this manner, whole fetal heart can be evaluated as the relation of three segments (atria, ventricles and the great arteries with each other, irrelevant of complexity of a possible cardiac anomaly. Presence of increased nuchal thickness during early gestation and abnormal four-chamber-view during ultrasonography by the obstetrician presents a clear indication for fetal echocardiography,however, one should keep in mind that 80-90% of the babies born with a congenital heart disease do not have a familial or maternal risk factor. In addition, it should be remembered that expectant mothers with diabetes mellitus pose an indication for fetal echocardiography.

  16. Methodologies of Uncertainty Propagation Calculation

    International Nuclear Information System (INIS)

    Chojnacki, Eric

    2002-01-01

    After recalling the theoretical principle and the practical difficulties of the methodologies of uncertainty propagation calculation, the author discussed how to propagate input uncertainties. He said there were two kinds of input uncertainty: - variability: uncertainty due to heterogeneity, - lack of knowledge: uncertainty due to ignorance. It was therefore necessary to use two different propagation methods. He demonstrated this in a simple example which he generalised, treating the variability uncertainty by the probability theory and the lack of knowledge uncertainty by the fuzzy theory. He cautioned, however, against the systematic use of probability theory which may lead to unjustifiable and illegitimate precise answers. Mr Chojnacki's conclusions were that the importance of distinguishing variability and lack of knowledge increased as the problem was getting more and more complex in terms of number of parameters or time steps, and that it was necessary to develop uncertainty propagation methodologies combining probability theory and fuzzy theory

    Bramson, Aaron L.

    2004-04-01

    This paper presents a generalized methodology for propagating known or estimated levels of individual source document truth reliability to determine the confidence level of a combined output. Initial document certainty levels are augmented by (i) combining the reliability measures of multiply sources, (ii) incorporating the truth reinforcement of related elements, and (iii) incorporating the importance of the individual elements for determining the probability of truth for the whole. The result is a measure of confidence in system output based on the establishing of links among the truth values of inputs. This methodology was developed for application to a multi-component situation awareness tool under development at the Air Force Research Laboratory in Rome, New York. Determining how improvements in data quality and the variety of documents collected affect the probability of a correct situational detection helps optimize the performance of the tool overall.

    Since the introduction of a design methodology for Dutch banknotes, the quality of Dutch paper currency has improved in more than one way. The methodology is question provides for (i) a design policy, which helps fix clear objectives; (ii) design management, to ensure a smooth cooperation between the graphic designer, printer, papermaker an central bank, (iii) a program of requirements, a banknote development guideline for all parties involved. This systematic approach enables an objective selection of design proposals, including security features. Furthermore, the project manager obtains regular feedback from the public by conducting market surveys. Each new design of a Netherlands Guilder banknote issued by the Nederlandsche Bank of the past 50 years has been an improvement on its predecessor in terms of value recognition, security and durability.

  4. Implementation impacts of PRL methodology

    1993-02-01

    This report responds to a DOE-SR request to evaluate the impacts from implementation of the proposed Plutonium Recovery Limit (PRL) methodology. The PRL Methodology is based on cost minimization for decisions to discard or recover plutonium contained in scrap, residues, and other plutonium bearing materials. Implementation of the PRL methodology may result in decisions to declare as waste certain plutonium bearing materials originally considered to be a recoverable plutonium product. Such decisions may have regulatory impacts, because any material declared to be waste would immediately be subject to provisions of the Resource Conservation and Recovery Act (RCRA). The decision to discard these materials will have impacts on waste storage, treatment, and disposal facilities. Current plans for the de-inventory of plutonium processing facilities have identified certain materials as candidates for discard based upon the economic considerations associated with extending the operating schedules for recovery of the contained plutonium versus potential waste disposal costs. This report evaluates the impacts of discarding those materials as proposed by the F Area De-Inventory Plan and compares the De-Inventory Plan assessments with conclusions from application of the PRL. The impact analysis was performed for those materials proposed as potential candidates for discard by the De-Inventory Plan. The De-Inventory Plan identified 433 items, containing approximately 1% of the current SRS Pu-239 inventory, as not appropriate for recovery as the site moves to complete the mission of F-Canyon and FB-Line. The materials were entered into storage awaiting recovery as product under the Department's previous Economic Discard Limit (EDL) methodology which valued plutonium at its incremental cost of production in reactors. An application of Departmental PRLs to the subject 433 items revealed that approximately 40% of them would continue to be potentially recoverable as product plutonium

    This issue of Systemic Practice and Action Research, celebrating the work of Peter Checkland, in the particular nature and development of soft systems methodology (SSM), would not have happened unless the work was seen by others as being important. No significant contribution to thinking happens without a secondary literature developing. Not surprisingly, many commentaries have accompanied the ongoing development of SSM. Some of these are insightful, some full of errors, and some include both...

  9. Methodological remarks on contraction theory

    DEFF Research Database (Denmark)

    Jouffroy, Jerome; Slotine, Jean-Jacques E.

    Because contraction analysis stems from a differential and incremental framework, the nature and methodology of contraction-based proofs are significantly different from those of their Lyapunov-based counterparts. This paper specifically studies this issue, and illustrates it by revisiting some c...... classical examples traditionally addressed using Lyapunov theory. Even in these cases, contraction tools can often yield significantly simplified analysis. The examples include adaptive control, robotics, and a proof of convergence of the deterministic Extended Kalman Filter....

    Two closely related aspects of artificial intelligence that have received comparatively little attention in the recent literature are research methodology, and the analysis of computational techniques that span multiple application areas. We believe both issues to be increasingly significant as Artificial Intelligence matures into a science and spins off major application efforts. It is imperative to analyze the repertoire of AI methods with respect to past experience, utility in new domains,...

  11. Developing Foucault's Discourse Analytic Methodology

    Directory of Open Access Journals (Sweden)

    Rainer Diaz-Bone

    2006-01-01

    Full Text Available A methodological position for a FOUCAULTian discourse analysis is presented. A sequence of analytical steps is introduced and an illustrating example is offered. It is emphasized that discourse analysis has to discover the system-level of discursive rules and the deeper structure of the discursive formation. Otherwise the analysis will be unfinished. Michel FOUCAULTs work is theoretically grounded in French structuralism and (the so called post-structuralism. In this paper, post-structuralism is not conceived as a means for overcoming of structuralism, but as a way of critically continuing the structural perspective. In this way, discursive structures can be related to discursive practices and the concept of structure can be disclosed (e. g. to inter-discourse or DERRIDAs concept of structurality. In this way, the structural methodology is continued and radicalized, but not given up. In this paper, FOUCAULTs theory is combined with the works of Michel PÊCHEUX and (especially for the sociology of knowledge and the sociology of culture Pierre BOURDIEU. The practice of discourse analysis is theoretically grounded. This practice can be conceived as a reflexive coupling of deconstruction and reconstruction in the material to be analyzed. This methodology therefore can be characterized as a reconstructive qualitative methodology. At the end of the article, forms of discourse analysis are criticized that do not intend to recover the system level of discursive rules and that do not intend to discover the deeper structure of the discursive formation (i. e. episteme, socio-episteme. These forms merely are commentaries of discourses (not their analyses, they remain phenomenological and are therefore: pre-structuralist. URN: urn:nbn:de:0114-fqs060168

  12. Software engineering methodologies and tools

    Wilcox, Lawrence M.

    1993-01-01

    Over the years many engineering disciplines have developed, including chemical, electronic, etc. Common to all engineering disciplines is the use of rigor, models, metrics, and predefined methodologies. Recently, a new engineering discipline has appeared on the scene, called software engineering. For over thirty years computer software has been developed and the track record has not been good. Software development projects often miss schedules, are over budget, do not give the user what is wanted, and produce defects. One estimate is there are one to three defects per 1000 lines of deployed code. More and more systems are requiring larger and more complex software for support. As this requirement grows, the software development problems grow exponentially. It is believed that software quality can be improved by applying engineering principles. Another compelling reason to bring the engineering disciplines to software development is productivity. It has been estimated that productivity of producing software has only increased one to two percent a year in the last thirty years. Ironically, the computer and its software have contributed significantly to the industry-wide productivity, but computer professionals have done a poor job of using the computer to do their job. Engineering disciplines and methodologies are now emerging supported by software tools that address the problems of software development. This paper addresses some of the current software engineering methodologies as a backdrop for the general evaluation of computer assisted software engineering (CASE) tools from actual installation of and experimentation with some specific tools.

  13. Methodology for technical risk assessment

    International Nuclear Information System (INIS)

    Waganer, L.M.; Zuckerman, D.S.

    1983-01-01

    A methodology has been developed for and applied to the assessment of the technical risks associated with an evolving technology. This methodology, originally developed for fusion by K. W. Billman and F. R. Scott at EPRI, has been applied to assess the technical risk of a fuel system for a fusion reactor. Technical risk is defined as the risk that a particular technology or component which is currently under development will not achieve a set of required technical specifications (i.e. probability of failure). The individual steps in the technical risk assessment are summarized. The first step in this methodology is to clearly and completely quantify the technical requirements for the particular system being examined. The next step is to identify and define subsystems and various options which appear capable of achieving the required technical performance. The subsystem options are then characterized regarding subsystem functions, interface requirements with the subsystems and systems, important components, developmental obstacles and technical limitations. Key technical subsystem performance parameters are identified which directly or indirectly relate to the system technical specifications. Past, existing and future technical performance data from subsystem experts are obtained by using a Bayesian Interrogation technique. The input data is solicited in the form of probability functions. Thus the output performance of the system is expressed as probability functions

  14. Methodology for astronaut reconditioning research.

    Beard, David J; Cook, Jonathan A

    2017-01-01

    Space medicine offers some unique challenges, especially in terms of research methodology. A specific challenge for astronaut reconditioning involves identification of what aspects of terrestrial research methodology hold and which require modification. This paper reviews this area and presents appropriate solutions where possible. It is concluded that spaceflight rehabilitation research should remain question/problem driven and is broadly similar to the terrestrial equivalent on small populations, such as rare diseases and various sports. Astronauts and Medical Operations personnel should be involved at all levels to ensure feasibility of research protocols. There is room for creative and hybrid methodology but careful systematic observation is likely to be more achievable and fruitful than complex trial based comparisons. Multi-space agency collaboration will be critical to pool data from small groups of astronauts with the accepted use of standardised outcome measures across all agencies. Systematic reviews will be an essential component. Most limitations relate to the inherent small sample size available for human spaceflight research. Early adoption of a co-operative model for spaceflight rehabilitation research is therefore advised. Copyright © 2016 Elsevier Ltd. All rights reserved.

    1999-04-01

    The work described in this report has been performed as a part of the RESTRAT Project FI4P-CT95-0021a (PL 950128) co-funded by the Nuclear Fission Safety Programme of the European Commission. The RESTRAT project has the overall objective of developing generic methodologies for ranking restoration techniques as a function of contamination and site characteristics. The project includes analyses of existing remediation methodologies and contaminated sites, and is structured in the following steps: characterisation of relevant contaminated sites; identification and characterisation of relevant restoration techniques; assessment of the radiological impact; development and application of a selection methodology for restoration options; formulation of generic conclusions and development of a manual. The project is intended to apply to situations in which sites with nuclear installations have been contaminated with radioactive materials as a result of the operation of these installations. The areas considered for remedial measures include contaminated land areas, rivers and sediments in rivers, lakes, and sea areas. Five contaminated European sites have been studied. Various remedial measures have been envisaged with respect to the optimisation of the protection of the populations being exposed to the radionuclides at the sites. Cost-benefit analysis and multi-attribute utility analysis have been applied for optimisation. Health, economic and social attributes have been included and weighting factors for the different attributes have been determined by the use of scaling constants. (au)

  16. A framework for the establishment of organizational risk indicators

    International Nuclear Information System (INIS)

    Oien, K.

    2001-01-01

    Organizational risk indicators are proposed as a tool for risk control during operation of offshore installations, as a complement to QRA-based indicators. An organizational factor framework is developed based on a review of existing organizational factor frameworks, research on safety performance indicators, and previous work on QRA-based indicators. The results comprise a qualitative organizational model, proposed organizational risk indicators, and a quantification methodology for assessing the impact of the organization on risk. The risk indicators, when validated, will aid in a frequent control of the risk in the periods between the updating of the quantitative risk assessments

    Traditional methods of projecting population health statistics, such as estimating future death rates, can give inaccurate results and lead to inferior or even poor policy decisions. A new "three-dimensional" method of forecasting vital health statistics is more accurate because it takes into account the delayed effects of the health risks being accumulated by today's younger generations. Applying this forecasting technique to the US obesity epidemic suggests that future death rates and health care expenditures could be far worse than currently anticipated. We suggest that public policy makers adopt this more robust forecasting tool and redouble efforts to develop and implement effective obesity-related prevention programs and interventions.

  3. Ecodesign of cosmetic formulae: methodology and application.

    2018-04-01

    This article describes an easy-to-use ecodesign methodology developed and applied since 2014 by the L'Oréal Group to improve the sustainable performance of its new products without any compromise on their cosmetic efficacy. Cosmetic products, after being used, are often discharged into the sewers and the aquatic compartment. This discharge is considered as dispersive and continuous. A consistent progress in reducing the environmental impact of cosmetic products can be achieved through focusing upon three strategic indicators: biodegradability, grey water footprint adapted for ecodesign (GWFE) and a global indicator, complementary to these two endpoints. Biodegradability represents the key process in the removal of organic ingredients from the environment. GWFE is defined herein as the theoretical volume of natural freshwater required to dilute a cosmetic formula after being used by the consumer, down to a concentration without any foreseeable toxic effects upon aquatic species. Finally, the complementary indicator highlights a possible alert on formula ingredients due to an unfavourable environmental profile based on hazard properties: for example Global Harmonization System/Classification, Labelling and Packaging (GHS/CLP) H410 classification or potential very persistent and very bioaccumulative (vPvB) classification. The ecodesign of a new cosmetic product can be a challenge as the cosmetic properties and quality of this new product should at least match the benchmark reference. As shown in the case studies described herein, new methodologies have been developed to maximize the biodegradability of cosmetic formulae, to minimize their GWFE and to limit the use of ingredients that present an unfavourable environmental profile, while reaching the highest standards in terms of cosmetic efficacy. By applying these methodologies, highly biodegradable products (≥ 95% based on ingredient composition) have been developed and marketed, with a low GWFE. This new

    Event Tree(ET)/Fault Tree(FT) are significant methodology in Probabilistic Safety Assessment(PSA) for Nuclear Power Plants(NPPs). ET/FT methodology has the advantage for users to be able to easily learn and model. It enables better communication between engineers engaged in the same field. However, conventional methodologies are difficult to cope with the dynamic behavior (e.g. operation mode changes or sequence-dependent failure) and integrated situation of mechanical failure and human errors. Meanwhile, new possibilities are coming for the improved PSA by virtue of the dramatic development on digital hardware, software, information technology, and data analysis.. More specifically, the computing environment has been greatly improved with being compared to the past, so we are able to conduct risk analysis with the large amount of data actually available. One method which can take the technological advantages aforementioned should be the dynamic PSA such that conventional ET/FT can have time- and condition-dependent behaviors in accident scenarios. In this paper, we investigated the various enabling techniques for the dynamic PSA. Even though its history and academic achievement was great, it seems less interesting from industrial and regulatory viewpoint. Authors expect this can contribute to better understanding of dynamic PSA in terms of algorithm, practice, and applicability. In paper, the overview for the dynamic PSA was conducted. Most of methodologies share similar concepts. Among them, DDET seems a backbone for most of methodologies since it can be applied to large problems. The common characteristics sharing the concept of DDET are as follows: • Both deterministic and stochastic approaches • Improves the identification of PSA success criteria • Helps to limit detrimental effects of sequence binning (normally adopted in PSA) • Helps to avoid defining non-optimal success criteria that may distort the risk • Framework for comprehensively considering

    1995-01-01

    Since United States of America federal legislation has required ozone depleting chemicals (class 1 & 2) to be banned from production, The National Aeronautics and Space Administration (NASA) and industry have been required to find other chemicals and methods to replace these target chemicals. This project was initiated as a development of a prioritization methodology suitable for assessing and ranking existing processes for replacement 'urgency.' The methodology was produced in the form of a workbook (NASA Technical Paper 3421). The final workbook contains two tools, one for evaluation and one for prioritization. The two tools are interconnected in that they were developed from one central theme - chemical replacement due to imposed laws and regulations. This workbook provides matrices, detailed explanations of how to use them, and a detailed methodology for prioritization of replacement technology. The main objective is to provide a GUIDELINE to help direct the research for replacement technology. The approach for prioritization called for a system which would result in a numerical rating for the chemicals and processes being assessed. A Quality Function Deployment (QFD) technique was used in order to determine numerical values which would correspond to the concerns raised and their respective importance to the process. This workbook defines the approach and the application of the QFD matrix. This technique: (1) provides a standard database for technology that can be easily reviewed, and (2) provides a standard format for information when requesting resources for further research for chemical replacement technology. Originally, this workbook was to be used for Class 1 and Class 2 chemicals, but it was specifically designed to be flexible enough to be used for any chemical used in a process (if the chemical and/or process needs to be replaced). The methodology consists of comparison matrices (and the smaller comparison components) which allow replacement technology

    Novak Zuber; Ivan Catton; Upendra S Rohatgi; Wolfgang Wulff

    2005-01-01

    Full text of publication follows: a quantitative methodology is developed, based on the concepts of hierarchy and synthesis, to integrate and organize information and data. The methodology uses scaling to synthesize experimental data and analytical results, and to provide quantitative criteria for evaluating the effects of various design and operating parameters that influence processes in a complex system such as a nuclear power plant or a related test facility. Synthesis and scaling are performed on three hierarchical levels: the process, component and system levels. Scaling on the process level determines the effect of a selected process on a particular state variable during a selected scenario. At the component level this scaling determines the effects various processes have on a state variable, and it ranks the processes according to their importance by the magnitude of the fractional change they cause on that state variable. At the system level the scaling determines the governing processes and corresponding components, ranking these in the order of importance according to their effect on the fractional change of system-wide state variables. The scaling methodology reveals on all levels the fractional change of state variables and is called therefore the Fractional Scaling Methodology (FSM). FSM synthesizes process parameters and assigns to each thermohydraulic process a dimensionless effect metric Ω = ωt, that is the product of the specific rate of fractional change ω and the characteristic time t. The rate of fractional change ω is the ratio of process transport rate over content of a preserved quantity in a component. The effect metric Ω quantifies the contribution of the process to the fractional change of a state variable in a given component. Ordering of a component effect metrics provides the hierarchy of processes in a component, then in all components and the system. FSM separates quantitatively dominant from minor processes and components and

  17. Indicating anthropogenic effectson urban water system - indicators and extension

    Strauch, G.; Ufz-Team

    2003-04-01

    Urban water systems are polluted by diffusive and direct contribution of anthropogenic activities. Besides industrial contaminants like aromatic and chlorinated HC and other persistent organic compounds, the urban aquatic environment is increasingly polluted by low concentrated but high eco-toxic compounds as pharmaceuticals, fragrances, plasticizers which most have disrupt endocrine functions, and trace elements carried in by surface and sub-surface waste water and seeping processes. This contamination could have a longtime impact on the urban ecosystem and on the human health. The interdisciplinary project on risk assessment of water pollution was initiated to explore new methodologies for assessing human activities on the urban water system and processes among urban watersheds. In a first assumption we used a flow model concept with in- and output and surface water transport represented by the city of Halle, Germany, and the river Saale. The river Saale acts as surface water system collecting waste water inputs along the city traverse. We investigated the anthropogenic effect on the urban water system using the indicators hydrological parameters, compound specific pattern of complex organic substances and trace elements, isotopic signatures of water (H, O) and dissolved substances (sulfate, DIC, nitrate), pathogens, and microbiota. A first balance modeling showed that main ions are not very sensitive concerning the direct urban input into the river. Depending on the discharge of the river in high and low flood stages the load of dissolved matter has no specific urban effect. However, the concentration pattern of fragrances (tonalid, galaxolid) and endocrine disrupters (t-nonylphenol) point to a different pollution along the city traverse: downstream of the sewage plant a higher load was observed in comparison to the upstream passage. Furthermore, a degradation ability of fungi and bacteria occurred in the bank sediments could be detected in lab experiments

  18. Risk indicators as a tool for risk control

    International Nuclear Information System (INIS)

    Oien, K.

    2001-01-01

    This paper presents a general methodology for the establishment of risk indicators that can be used as a tool for risk control during operation of offshore petroleum installations. The risk indicators established are based on the platform specific quantitative risk analysis (QRA). The general methodology is evaluated against comparable approaches both in offshore and nuclear industry. There are two distinct features of this methodology. The first is that it is truly risk-based with the intention of covering the total risk picture. The second is that the identification of the risk factors contributing most to the total risk is based on realistic changes of each factor assessed by the platform personnel, not a theoretically assumed change. The set of risk indicators for one specific installation is presented along with test results

    2015-09-01

    As the body of literature on femoroacetabular impingement (FAI) continues to grow, clinicians turn to systematic reviews to remain current with the best available evidence. The quality of systematic reviews in the FAI literature is currently unknown. The goal of this study was to assess the quality of the reporting of systematic reviews addressing FAI over the last 11 years (2003-2014) and to identify the specific methodological shortcomings and strengths. A search of the electronic databases, MEDLINE, EMBASE and PubMed, was performed to identify relevant systematic reviews. Methodological quality was assessed by two reviewers using the revised assessment of multiple systematic reviews (R-AMSTAR) scoring tool. An intraclass correlation coefficient (ICC) with 95 % confidence intervals (CI) was used to determine agreement between reviewers on R-AMSTAR quality scores. A total of 22 systematic reviews were assessed for methodological quality. The mean consensus R-AMSTAR score across all studies was 26.7 out of 40.0, indicating fair methodological quality. An ICC of 0.931, 95 % CI 0.843-0.971 indicated excellent agreement between reviewers during the scoring process. The systematic reviews addressing FAI are generally of fair methodological quality. Use of tools such as the R-AMSTAR score or PRISMA guidelines while designing future systematic reviews can assist in eliminating methodological shortcomings identified in this review. These shortcomings need to be kept in mind by clinicians when applying the current literature to their patient populations and making treatment decisions. Systematic reviews of highest methodological quality should be used by clinicians when possible to answer clinical questions.

  20. Researching Lean: Methodological Implications of Loose Definitions

    Directory of Open Access Journals (Sweden)

    Mikael Brännmark

    2012-12-01

    Full Text Available Recently, Lean Production (Lean has become a prevailing management concept in Sweden. However, previous research seems to show that the Lean concept and the impact of Lean vary considerably between organizations. This paper illustrates some key methodological issues that need to be considered when researching loosely defined management concepts such as Lean. The paper is based on a review of the literature and five comparative Swedish cases studies. Our study indicates that Lean has changed over time and that operationalization and interpretations of the concept vary considerably. This study concludes that future Lean studies should include a thorough assessment of the Lean interventions, study settings, and in particular non-Lean factors mediating the outcomes of Lean-inspired change programs.

    Full Text Available Monitoring water, sanitation, and hygiene (WaSH is important to track progress, improve accountability, and demonstrate impacts of efforts to improve conditions and services, especially in low- and middle-income countries. Indicator selection methods enable robust monitoring of WaSH projects and conditions. However, selection methods are not always used and there are no commonly-used methods for selecting WaSH indicators. To address this gap, we conducted a systematic review of indicator selection methods used in WaSH-related fields. We present a summary of indicator selection methods for environment, international development, and water. We identified six methodological stages for selecting indicators for WaSH: define the purpose and scope; select a conceptual framework; search for candidate indicators; determine selection criteria; score indicators against criteria; and select a final suite of indicators. This summary of indicator selection methods provides a foundation for the critical assessment of existing methods. It can be used to inform future efforts to construct indicator sets in WaSH and related fields.

    The advancement knowledge in molecular and cell biology, biochemistry, medicine and pharmacology, which has taken place during the last 50 years, after World War II finalization, is really outstanding. It can be safely said that this fact is principally due to the application of radioisotope techniques. The research on metabolisms, biodistribution of pharmaceuticals, pharmacodynamics, etc., is mostly carried out by means of techniques employing radioactive materials. Radioisotopes and radiation are frequently used in medicine both as diagnostic and therapeutic tools. The radioimmunoanalysis is today a routine method in endocrinology and in general clinical medicine. The receptor determination and characterization is a steadily growing methodology used in clinical biochemistry, pharmacology and medicine. The use of radiopharmaceuticals and radiation of different origins, for therapeutic purposes, should not be overlooked. For these reasons, the importance to teach radioisotope methodology is steadily growing. This is principally the case for specialization at the post-graduate level but at the pre graduate curriculum it is worthwhile to give some elementary theoretical and practical notions on this subject. These observations are justified by a more than 30 years teaching experience at both levels at the School of Pharmacy and Biochemistry of the University of Buenos Aires, Argentina. In 1960 we began to teach Physics III, an obligatory pregraduate course for biochemistry students, in which some elementary notions of radioactivity and measurement techniques were given. Successive modifications of the biochemistry pregraduate curriculum incorporated radiochemistry as an elective subject and since 1978, radioisotope methodology, as obligatory subject for biochemistry students. This subject is given at the radioisotope laboratory during the first semester of each year and its objective is to provide theoretical and practical knowledge to the biochemistry students, even

  13. Safeguarding the fuel cycle: Methodologies

    Gruemm, H.

    1984-01-01

    The effectiveness of IAEA safeguards is characterized by the extent to which they achieve their basic purpose - credible verification that no nuclear material is diverted from peaceful uses. This effectiveness depends inter alia but significantly on manpower in terms of the number and qualifications of inspectors. Staff increases will be required to improve effectiveness further, if this is requested by Member States, as well as to take into account new facilities expected to come under safeguards in the future. However, they are difficult to achieve due to financial constraints set by the IAEA budget. As a consequence, much has been done and is being undertaken to improve utilization of available manpower, including standardization of inspection procedures; improvement of management practices and training; rationalization of planning, reporting, and evaluation of inspection activities; and development of new equipment. This article focuses on certain aspects of the verification methodology presently used and asks: are any modifications of this methodology conceivable that would lead to economies of manpower, without loss of effectiveness. It has been stated in this context that present safeguards approaches are ''facility-oriented'' and that the adoption of a ''fuel cycle-oriented approach'' might bring about the desired savings. Many studies have been devoted to this very interesting suggestion. Up to this moment, no definite answer is available and further studies will be necessary to come to a conclusion. In what follows, the essentials of the problem are explained and some possible paths to a solution are discussed

  14. Methodology for combining dynamic responses

    International Nuclear Information System (INIS)

    Cudlin, R.; Hosford, S.; Mattu, R.; Wichman, K.

    1978-09-01

    The NRC has historically required that the structural/mechanical responses due to various accident loads and loads caused by natural phenomena, (such as earthquakes) be combined when analyzing structures, systems, and components important to safety. Several approaches to account for the potential interaction of loads resulting from accidents and natural phenomena have been used. One approach, the so-called absolute or linear summation (ABS) method, linearly adds the peak structural responses due to the individual dynamic loads. In general, the ABS method has also reflected the staff's conservative preference for the combination of dynamic load responses. A second approach, referred to as SRSS, yields a combined response equal to the square root of the sum of the squares of the peak responses due to the individual dynamic loads. The lack of a physical relationship between some of the loads has raised questions as to the proper methodology to be used in the design of nuclear power plants. An NRR Working Group was constituted to examine load combination methodologies and to develop a recommendation concerning criteria or conditions for their application. Evaluations of and recommendations on the use of the ABS and SRSS methods are provided in the report

  1. An EPRI methodology for determining and monitoring simulator operating limits

    International Nuclear Information System (INIS)

    Eichelberg, R.; Pellechi, M.; Wolf, B.; Colley, R.

    1989-01-01

    Of paramount concern to nuclear utilities today is whether their plant-referenced simulator(s) comply with ANSI/ANS 3.5-1985. Of special interest is Section 4.3 of the Standard which requires, in part, that a means be provided to alert the instructor when certain parameters approach values indicative of events beyond the implemented model or known plant behavior. EPRI established Research Project 2054-2 to develop a comprehensive plan for determining, monitoring, and implementing simulator operating limits. As part of the project, a survey was conducted to identify the current/anticipated approach each of the sampled utilities was using to meet the requirements of Section 4.3. A preliminary methodology was drafted and host utilities interviewed. The interview process led to redefining the methodology. This paper covers the objectives of the EPRI project, survey responses, overview of the methodology, resource requirements and conclusions

    The United States Nuclear Regulatory Commission (NRC) is sponsoring a research program to develop an improved understanding of the human factors hardware, and accident consequence issues that dominate the risk from an Interfacing Systems Loss-of-Coolant Accident (ISLOCA) at a nuclear power plant. To accomplish this program, a methodology has been developed for estimating the core damage frequency and risk associated with an ISLOCA. The steps of the methodology are described with emphasis on one step which is unique, estimation of the probability of rupture of the low pressure systems. A trial application of the methodology was made for a Pressurized Water Reactor (PWR). The results are believed to be plant specific and indicate that human errors during startup and shutdown could be significant contributors to ISLOCA risk at the plant evaluated. 10 refs

  3. Methodology is more than research design and technology.

    The Society for Computers in Psychology has been at the forefront of disseminating information about advances in computer technology and their applications for psychologists. Although technological advances, as well as clean research designs, are key contributors to progress in psychological research, the justification of methodological rules for interpreting data and making theory choices is at least as important. Historically, methodological beliefs and practices have been justified through intuition and logic, an approach known as foundationism. However, naturalism, a modern approach in the philosophy of science inspired by the work of Thomas S. Kuhn, indicates that all aspects of scientific practice, including its methodology, should be evaluated empirically. This article examines implications of the naturalistic approach for psychological research methods in general and for the current debate that is often framed as one of qualitative versus quantitative methods.

    The official INPRO User Manual in the area of proliferation resistance is being processed for the evaluation of innovative nuclear energy systems. Proliferation resistance is one of the goals to be satisfied for future nuclear energy systems in INPRO. The features of currently updated and released INPRO methodology were introduced on basic principles, user requirements and indicators. The criteria for an acceptance limit were specified. The DUPIC fuel cycle was evaluated based on the updated INPRO methodology for the applicability of the INPRO User Manual. However, the INPRO methodology has some difficulty in quantifying the multiplicity and robustness as well as the total cost to improve proliferation resistance. Moreover, the integration method for the evaluation results still needs to be improved.

    2015-05-01

    Full Text Available The methodologies which are considered the most promising for irrigation management are those based on the analysis of the water status of the plants themselves. This justifies the study and improvement of indicators based on automatic and continuous measures to enable real-time monitoring data, as indices from sap flow, dendrometry and leaf turgor pressure techniques. The aim of this paper is to analyze such methodologies in order to demonstrate their principles, advantages and challenges. In conclusion, the methodologies analyzed still have many technological advances and challenges before being presented to the final user. The future research should work these tools for elaboration of technical indexes that allow their simplification, on the instrumental point of view, and the interpretation of their results.

  6. Should researchers use single indicators, best indicators, or multiple indicators in structural equation models?

    Directory of Open Access Journals (Sweden)

    Hayduk Leslie A

    2012-10-01

    Full Text Available Abstract Background Structural equation modeling developed as a statistical melding of path analysis and factor analysis that obscured a fundamental tension between a factor preference for multiple indicators and path modeling’s openness to fewer indicators. Discussion Multiple indicators hamper theory by unnecessarily restricting the number of modeled latents. Using the few best indicators – possibly even the single best indicator of each latent – encourages development of theoretically sophisticated models. Additional latent variables permit stronger statistical control of potential confounders, and encourage detailed investigation of mediating causal mechanisms. Summary We recommend the use of the few best indicators. One or two indicators are often sufficient, but three indicators may occasionally be helpful. More than three indicators are rarely warranted because additional redundant indicators provide less research benefit than single indicators of additional latent variables. Scales created from multiple indicators can introduce additional problems, and are prone to being less desirable than either single or multiple indicators.

  7. Methodology for flammable gas evaluations

    Energy Technology Data Exchange (ETDEWEB)

    Hopkins, J.D., Westinghouse Hanford

    1996-06-12

    There are 177 radioactive waste storage tanks at the Hanford Site. The waste generates flammable gases. The waste releases gas continuously, but in some tanks the waste has shown a tendency to trap these flammable gases. When enough gas is trapped in a tank`s waste matrix, it may be released in a way that renders part or all of the tank atmosphere flammable for a period of time. Tanks must be evaluated against previously defined criteria to determine whether they can present a flammable gas hazard. This document presents the methodology for evaluating tanks in two areas of concern in the tank headspace:steady-state flammable-gas concentration resulting from continuous release, and concentration resulting from an episodic gas release.

    Eldiwany, B.H.; Sharma, V.; Kalsi, M.S.; Wolfe, K.

    1994-01-01

    As part of the Motor-Operated Valve (MOV) Performance Prediction Program, the Electric Power Research Institute has sponsored the development of methodologies for predicting thrust and torque requirements of gate, globe, and butterfly MOVs. This paper presents the methodology that will be used by utilities to calculate the dynamic torque requirements for butterfly valves. The total dynamic torque at any disc position is the sum of the hydrodynamic torque, bearing torque (which is induced by the hydrodynamic force), as well as other small torque components (such as packing torque). The hydrodynamic torque on the valve disc, caused by the fluid flow through the valve, depends on the disc angle, flow velocity, upstream flow disturbances, disc shape, and the disc aspect ratio. The butterfly valve model provides sets of nondimensional flow and torque coefficients that can be used to predict flow rate and hydrodynamic torque throughout the disc stroke and to calculate the required actuation torque and the maximum transmitted torque throughout the opening and closing stroke. The scope of the model includes symmetric and nonsymmetric discs of different shapes and aspects ratios in compressible and incompressible fluid applications under both choked and nonchoked flow conditions. The model features were validated against test data from a comprehensive flowloop and in situ test program. These tests were designed to systematically address the effect of the following parameters on the required torque: valve size, disc shapes and disc aspect ratios, upstream elbow orientation and its proximity, and flow conditions. The applicability of the nondimensional coefficients to valves of different sizes was validated by performing tests on 42-in. valve and a precisely scaled 6-in. model. The butterfly valve model torque predictions were found to bound test data from the flow-loop and in situ testing, as shown in the examples provided in this paper

    Full Text Available The article considers methodological foundations of the system anthropologicalpsychology (SAP as a scientific branch developed by a well-represented groupof Siberian scientists. SAP is a theory based on axiomatics of cultural-historicalpsychology of L.S. Vygotsky and transspective analysis as a specially developedmeans to define the tendencies of science developing as a self-organizing system.Transspective analysis has revealed regularities in a constantly growing complexityof professional-psychological thinking along the course of emergence ofscientific cognition. It has proved that the field of modern psychology is shapedby theories constructed with ideation of different grades of complexity. The concept“dynamics of the paradigm of science” is introduced; it allows transitions tobe acknowledged from ordinary-binary logic characteristics of the classical scienceto a binary-ternary logic, adequate to non-classical science and then to aternary-multidimensional logic, which is now at the stage of emergence. The latteris employed in SAP construction. It involves the following basic methodologicalprinciples: the principle of directed (selective interaction and the principle ofgenerative effect of selective interaction. The concept of “complimentary interaction”applied in natural as well as humanitarian sciences is reconsidered in thecontext of psychology. The conclusion is made that the principle of selectivity anddirectedness of interaction is relevant to the whole Universe embracing all kindsof systems including the living ones. Different levels of matter organization representingsemantic structures of various complexity use one and the same principleof meaning making through which the Universe ensures its sustainability asa self-developing phenomenon. This methodology provides an explanation fornature and stages of emergence of multidimensional life space of an individual,which comes as a foundation for generation of such features of

  16. CIAU methodology and BEPU applications

    Best-Estimate calculation results from complex thermal-hydraulic system codes (like Relap5, Cathare, Athlet, Trace, etc..) are affected by unavoidable approximations that are unpredictable without the use of computational tools that account for the various sources of uncertainty. Therefore the use of best-estimate codes within the reactor technology, either for design or safety purposes, implies understanding and accepting the limitations and the deficiencies of those codes. Uncertainties may have different origins ranging from the approximation of the models, to the approximation of the numerical solution, and to the lack of precision of the values adopted for boundary and initial conditions. The amount of uncertainty that affects a calculation may strongly depend upon the codes and the modeling techniques (i.e. the code's users). A consistent and robust uncertainty methodology must be developed taking into consideration all the above aspects. The CIAU (Code with the capability of Internal Assessment of Uncertainty) and the UMAE (Uncertainty Methodology based on Accuracy Evaluation) methods have been developed by University of Pisa (UNIPI) in the framework of a long lasting research activities started since 80's and involving several researchers. CIAU is extensively discussed in the available technical literature, Refs. [1, 2, 3, 4, 5, 6, 7], and tens of additional relevant papers, that provide comprehensive details about the method, can be found in the bibliography lists of the above references. Therefore, the present paper supplies only 'spot-information' about CIAU and focuses mostly on the applications to some cases of industrial interest. In particular the application of CIAU to the OECD BEMUSE (Best Estimate Methods Uncertainty and Sensitivity Evaluation, [8, 9]) project is discussed and a critical comparison respect with other uncertainty methods (in relation to items like: sources of uncertainties, selection of the input parameters and quantification of

  17. The Methodological Dynamism of Grounded Theory

    2015-11-01

    Full Text Available Variations in grounded theory (GT interpretation are the subject of ongoing debate. Divergences of opinion, genres, approaches, methodologies, and methods exist, resulting in disagreement on what GT methodology is and how it comes to be. From the postpositivism of Glaser and Strauss, to the symbolic interactionist roots of Strauss and Corbin, through to the constructivism of Charmaz, the field of GT methodology is distinctive in the sense that those using it offer new ontological, epistemological, and methodological perspectives at specific moments in time. We explore the unusual dynamism attached to GT’s underpinnings. Our view is that through a process of symbolic interactionism, in which generations of researchers interact with their context, moments are formed and philosophical perspectives are interpreted in a manner congruent with GT’s essential methods. We call this methodological dynamism, a process characterized by contextual awareness and moment formation, contemporaneous translation, generational methodology, and methodological consumerism.

    Eileen Carey, RNID, BSc. (hons, MSc.

    2010-12-01

    Full Text Available Classic grounded theory (CGT methodology is a general methodology whereby the researcher aims to develop an emergent conceptual theory from empirical data collected by the researcher during the research study. Gaining ethical approval from relevant ethics committees to access such data is the starting point for processing a CGT study. The adoption of the Universal Declaration on Bioethics and Human Rights (UNESCO, 2005 is an indication of global consensus on the importance of research ethics. There is, however, a wide variation of health research systems across countries and disciplines (Hearnshaw 2004. Institutional Research Boards (IRB or Research Ethics Committees (REC have been established in many countries to regulate ethical research ensuring that researchers agree to, and adhere to, specific ethical and methodological conditions prior to ethical approval being granted. Interestingly, both the processes and outcomes through which the methodological aspects pertinent to CGT studies are agreed between the researcher and ethics committee remain largely ambiguous and vague. Therefore, meeting the requirements for ethical approval from ethics committees, while enlisting the CGT methodology as a chosen research approach, can be daunting for novice researchers embarking upon their first CGT study.

  3. Unification of the methodology of competitiveness evaluation

    2016-05-01

    Full Text Available The purpose of the study is the comparison of the modern methods of competitiveness evaluation and testing the results in practice at a production plant in order to unify the methodology. Analysis of the publications shows that the existing diversity in methods of the competitiveness evaluation complicates the choice of a method and interpretation of the results, which confirms the need to classify and unify the methods available today. The authors suggest that the standardized method of competitiveness evaluation should combine matrix and graphical methods. In our study, we have shown that SWOT-analysis should be carried out in two stages: firstly, it is necessary to determine the strengths and weaknesses of the company, taking into account the following factors: marketing, production, economic and financial situation, technology, the administration and personnel; secondly, it is essential to assess the opportunities and threats with the allowance for the political, legal, and economic situation, the impact of market as well as social, cultural and natural environmental factors. The proposed methodology of competitiveness evaluation has been tested at the industrial enterprise "Olvita ltd", which is dynamically developing and successfully operates on the food market of Ukraine; it specializes in processing, logistics and distribution of fresh and frozen vegetables, fruits and berries, as well as ready-to cook meat products. The results have shown that the competitiveness evaluation remains a pressing issue that requires simple and fairly demonstrative methods, one of which is a method that combines both graphical and matrix approaches. The advantage of the proposed method is its sufficiently high visualizations and record of personal approaches in evaluating the scores for strengths and weaknesses as well as opportunities and threats. In the future, the authors are planning to examine and systemize the indicators used in the competitiveness

Also, using methodology of the International Labor Organizationcorrelcation between the amount of accident fatalities and general number of accidents in Ukraine and EU countries (Austria, GreatBritain, Germany, Denmark, Norway, Poland, Hungry, Finland, France is defined. It is shown that in spite of the positive dynamicsof decreasing amount of occupational injuries, the number of occupational diseases in Ukraine always increases. The comparativeanalysis of the ratio of the number of accident fatalities to the total number of registered accidents showed that, on average, Ukraineexceeds the EU countries by this indicator by 100 times.It is noted, that such negative indicators (in particular, increasing amount of occupational diseases, may occure because ofimperfect methodology for identifying the risks of professional dangerous.Also, it is ascertained that basing on the existed methodology, the identefication process of occupational dangerous isquite subjective, which reduces objectivity of conducting quantitative assessment. In order to eliminate defined drawnbacks it is firsttime proposed to use corresponding integral criterion to conduct the process of quantitative risk assessmentTo solve this problem authors formulate and propose an algorithm of improving methodology of a process of analysing dangerousand harmful production effects (DHPE which are the mainest reasons of occupational dangerous.The proposed algorithm includes implementation of four following successive steps: DHPE identification, indication of theirmaximum allowed threshold of concentrations (levels, identification of the sources of identified DHPE, esimation of consequencesof manifestation.The improved proposed methodology allows indentify risks of occurrence occupational dangerous in systems

    Full Text Available La forêt d’Amazonie est un des biomes les plus riches et les plus importants de la Terre. Cependant, son avenir est gravement menacé par les changements climatiques. L’effet de ces changements est indissociable de celui des activités humaines. Ainsi, la déforestation est responsable de plus de la moitié des émissions de gaz à effet de serre du Brésil. La lutte contre les changements climatique au Brésil passe donc en premier lieu par la lutte contre la déforestation. Cette lutte fait face aux enjeux actuels du développement en Amazonie, en premier lieu l’élevage et l’agriculture à grande échelle. Certains éléments des politiques récentes du Brésil vont dans le sens d’un développement moins « sauvage » en Amazonie, mais se heurtent à des intérêts économiques et politiques. Les initiatives internationales comme Reduced Emissions from Deforestation and forest Degradation (REDD, dans le cadre d’un accord climatique, peuvent fournir des incitatifs économiques cruciaux. Il est dans tous les cas primordial qu’un tel développement soit adapté à la réalité amazonienne et se fasse en collaboration avec les populations locales dans une optique de développement social autant qu’écologique ou économique.The Amazon rainforest is one of most important ecosystems on earth and a biodiversity hotspot. Its future is however in peril due to the effects of climate change and human activities. Climate models predict a severe die-back of the Amazon forest by the end of this century, accompanied by the release of vast quantities of carbon actually stored in the vegetation. Deforestation is currently responsible for over one half of Brazil’s greenhouse gas emissions. Fighting deforestation is therefore Brazil’s most efficient way to reduce its emissions. This is however contrary to current development schemes in the Amazon region, and in particular large scale agricultural and cattle raising farms. However, Brazil

    Preliminary studies preceding building of a nuclear facility aim at assessing the choice of a site and establishing operating and control procedures. These studies are of two types. Studies on the impact of environment on the nuclear facility to be constructed form one type and studies on the impact of nuclear facilities on the environment form the second type. A methodology giving a framework to studies of second type is presented. These studies are undertaken to choose suitable sites for nuclear facilities. After a preliminary selection of a site based on the first estimate, a detailed site study is undertaken. The procedure for this consists of five successive phases, namely, (1) an inquiry assessing the initial state of the site, (2) an initial synthesis of accumulated information for assessing the health and safety consequences of releases, (3) laboratory and field studies simulating the movement of waste products for a quantitative assessment of effects, (4) final synthesis for laying down the release limits and radiological control methods, and (5) conclusions based on comparing the data of final synthesis to the limits prescribed by regulations. These five phases are outlined. Role of periodic reassessments after the facility is in operation for same time is explained. (M.G.B.)

  16. Zika detection: comparison of methodologies

    Tatiana Elias Colombo

    Full Text Available ABSTRACT Many countries in the Americas have detected local transmission of multiple arboviruses that cause febrile illnesses. Therefore, laboratory testing has become an important tool for confirming the etiology of these diseases. The present study aimed to compare the sensitivity and specificity of three different Zika virus detection assays. One hundred serum samples from patients presenting with acute febrile symptoms were tested using a previously reported TaqMan® RT-qPCR assay. We used a SYBR® Green RT-qPCR and a conventional PCR methodologies to compare the results. Of the samples that were determined to be negative by the TaqMan® RT-qPCR assay, 100% (Kappa = 0.670 were also found to be negative by SYBR® Green RT-qPCR based on Tm comparison; however, 14% (Kappa = 0.035 were found to be positive by conventional PCR followed by agarose gel electrophoresis. The differences between the ZIKV strains circulating worldwide and the low viremia period can compromise diagnostic accuracy and thereby the accuracy of outbreak data. Therefore, improved assays are required to improve the diagnosis and surveillance of arbovirus.

    The objective of evidence-based medicine is to employ the best scientific information available to apply to clinical practice. Understanding and interpreting the scientific evidence involves understanding the available levels of evidence, where systematic reviews and meta-analyses of clinical trials are at the top of the levels-of-evidence pyramid. The review process should be well developed and planned to reduce biases and eliminate irrelevant and low-quality studies. The steps for implementing a systematic review include (i) correctly formulating the clinical question to answer (PICO), (ii) developing a protocol (inclusion and exclusion criteria), (iii) performing a detailed and broad literature search and (iv) screening the abstracts of the studies identified in the search and subsequently of the selected complete texts (PRISMA). Once the studies have been selected, we need to (v) extract the necessary data into a form designed in the protocol to summarise the included studies, (vi) assess the biases of each study, identifying the quality of the available evidence, and (vii) develop tables and text that synthesise the evidence. A systematic review involves a critical and reproducible summary of the results of the available publications on a particular topic or clinical question. To improve scientific writing, the methodology is shown in a structured manner to implement a systematic review. Copyright © 2018 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    2015-06-01

    The process of designing a questionnaire is complicated. Many questionnaires on nursing phenomena have been developed and used by nursing researchers. The purpose of this paper was to discuss questionnaire design and factors that should be considered when using existing scales. Methodological issues were discussed, such as factors in the design of questions, steps in developing questionnaires, wording and formatting methods for items, and administrations methods. How to use existing scales, how to facilitate cultural adaptation, and how to prevent socially desirable responding were discussed. Moreover, the triangulation method in questionnaire development was introduced. Steps were recommended for designing questions such as appropriately operationalizing key concepts for the target population, clearly formatting response options, generating items and confirming final items through face or content validity, sufficiently piloting the questionnaire using item analysis, demonstrating reliability and validity, finalizing the scale, and training the administrator. Psychometric properties and cultural equivalence should be evaluated prior to administration when using an existing questionnaire and performing cultural adaptation. In the context of well-defined nursing phenomena, logical and systematic methods will contribute to the development of simple and precise questionnaires.
