    Vertical profiles of 3-D wind velocity are retrieved from triple range-height-indicator (RHI) scans performed with multiple simultaneous scanning Doppler wind lidars. This test is part of the eXperimental Planetary boundary layer Instrumentation Assessment (XPIA) campaign carried out at the Boulder Atmospheric Observatory. The three wind velocity components are retrieved and then compared with the data acquired through various profiling wind lidars and high-frequency wind data obtained from sonic anemometers installed on a 300 m meteorological tower. The results show that the magnitude of the horizontal wind velocity and the wind direction obtained from the triple RHI scans are generally retrieved with good accuracy. However, poor accuracy is obtained for the evaluation of the vertical velocity, which is mainly due to its typically smaller magnitude and to the error propagation connected with the data retrieval procedure and accuracy in the experimental setup.

    Tanner, David E.

    1981-01-01

    A nuclear reactor system is described in which a position indicator is provided for detecting and indicating the position of a movable element inside a pressure vessel. The movable element may be a valve element or similar device which moves about an axis. Light from a light source is transmitted from a source outside the pressure vessel to a first region inside the pressure vessel in alignment with the axis of the movable element. The light is redirected by a reflector prism to a second region displaced radially from the first region. The reflector prism moves in response to movement of the movable element about its axis such that the second region moves arcuately with respect to the first region. Sensors are arrayed in an arc corresponding to the arc of movement of the second region and signals are transmitted from the sensors to the exterior of the reactor vessel to provide indication of the position of the movable element.

    Pollutants in the environment cause more and more situations of burden for living beings. In certain organisms, i.e. in biological indicators, there is a correlation between the extent of the damage and the degree of the burden. That is why environmental burdens can be recognized and, in part, be quantitatively recorded. Depending of the choice of materials and the damage parameters the respective differentiated statements can be made. Compared to technical measuring stations biological indicators facilitate the assessment of situations of burden with the help of biological-ecological parameters.

  11. Indicators+: a proposal for everyday peace indicators.

    Science.gov (United States)

    Mac Ginty, Roger

    2013-02-01

    Many of the approaches to measuring peace favoured by international organisations, INGOs and donor governments are deficient. Their level of analysis is often too broad or too narrow, and their aggregated statistical format often means that they represent the conflict-affected area in ways that are meaningless to local communities. This article takes the form of a proposal for a new generation of locally organised indicators that are based in everyday life. These indicators are inspired by practice from sustainable development in which indicators are crowd sourced. There is the potential for these to become 'indicators+' or part of a conflict transformation exercise as communities think about what peace might look like and how it could be realised. The article advocates a form of participatory action research that would be able to pick up the textured 'hidden transcript' found in many deeply divided societies and could allow for better targeted peacebuilding and development assistance.

    Hardt, Daniel; Asher, Nicholas; Hunter, Julie

    2013-01-01

    This paper compares two views on the status of indices in syntactic and logical representations. On a structural view, indices are syntactic formants on a par with node labels and phrase bracketings, and are thus a part of the logical forms that are derived from syntactic representations....... On the process view, an index is not a syntactic object at all, but rather, an indication of the output of a resolution process.In this paper we argue that a recent body of data provides a clear empirical basis for distinguishing between these two views of indices. We argue that cases of sloppy VP ellipsis pose...

  1. Evaluating Living Standard Indicators

    Directory of Open Access Journals (Sweden)

    Birčiaková Naďa

    2015-09-01

    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 Arctic is undergoing unprecedented change. Indicators of change enable better decision-making at the community to policy levels. The results presented here focus on a subset of physical, biological, societal, and economic indicators of Arctic change recommended in one of a group of papers emanating from the earlier National Climate Indicators System (NCIS) work led by Kenney et al. (2016). The intent of the NCIS was to establish a "system of physical, natural, and societal indicators that communicate and inform decisions about key aspects of the physical climate, climate impacts, vulnerabilities, and preparedness" in support of the sustained U.S. National Climate Assessment. Our analysis, guided by a tailored selection and recommendation criteria, resulted in a list of "existing" indicators, as well as those "in development", "recommended", and "aspirational". A goal of this effort is to identify a set of both lagging and leading indicators that is based on reliable and sustained data sources with known user communities. We intend for these indicators to guide decision-makers in their responses to climate change, and ideally help inform decisions of groups like the Arctic Council and U.S. Global Change Research Program (USGCRP) as they develop plans and priorities.

    Science.gov (United States)

    Králík, J; Tomsů, M; Král, V

    1989-04-01

    The authors define, based on experience with 55 retrosternal oesophagocoloplasties, the indications for this operation. They divide the indications into three groups and describe them as 1. the most suitable operation, 2. as the only possible replacement of the oesophagus, 3. as a palliative operation in an otherwise insolvable disphagia due to an inoperable tumour. They emphasize the wide range of indications for the operation which can be implemented without influencing the basic disease of the oesophagus and which makes it possible to apply combined treatment. The operation, though pretentious and time consuming, has the advantage of an extrathoracic approach. As to technical aspects, the authors emphasize the importance to select a portion of the gut with an adequate blood supply. This demand is usually met by the transverse colon on a vascular pedicle of the vasa colica sin.; they also mention the conditions of safe deposition of the gut in the retrosternal tunnel. The paper is supplemented by several case-histories of particularly interesting and difficult situations. If the indication range of the operation and its technical principles are respected and the surgeon is experienced, the failures of the operation are proportional to the severity of the basic disease.

  19. New power quality indices

    2007-07-01

    The proliferation of nonlinear loads connected to power systems has led to growing concerns about power quality. This study used a high-resolution spectrum estimation method to measure the spectral parameters of distorted waveforms encountered in power systems. Power quality indices were developed using the method, and the frequency and amplitude estimation errors were compared with errors obtained using Fourier-based techniques. The root multiple signal classification (MUSIC) method used an estimated covariance matrix to compute the signal zeros from the power system. The MUSIC method was compared with the estimation of signal parameters via rotational invariance technique (ESPRIT), which used the naturally existing shift invariance between discrete time series that resulted in rotational invariance between corresponding signal subspaces. The study demonstrated that the main sources of errors using ESPRIT occurred in estimates of the matrix. Matrix errors cause errors in eigenvalue estimations, which can in turn be regarded as a performance index of ESPRIT. The mean square error method was computed. The study showed that the ESPRIT method was faster during shorter data runs, but became slower than the MUSIC method as data lengths increased. The study also demonstrated that higher values obtained using Fourier-based techniques were caused by spectral leakage. It was concluded that parametric spectral estimation methods can be used to accurately analyze waveforms in power systems. 18 refs., 5 figs.

    We introduce the concept of the ensemble averaging for financial markets. We address the question of equality of ensemble and time averaging in their sequence and investigate if these averagings are equivalent for large amount of equity indices and branches. We start with the model of Gaussian-distributed returns, equal-weighted stocks in each index and absence of correlations within a single day and show that even this oversimplified model captures already the run of the corresponding index reasonably well due to its self-averaging properties. We introduce the concept of the instant cross-sectional volatility and discuss its relation to the ordinary time-resolved counterpart. The role of the cross-sectional volatility for the description of the corresponding index as well as the role of correlations between the single stocks and the role of non-Gaussianity of stock distributions is briefly discussed. Our model reveals quickly and efficiently some anomalies or bubbles in a particular financial market and gives an estimate of how large these effects can be and how quickly they disappear.

    Progress to forecast key space weather parameters using SIFT (Solar Indices Forecasting Tool) with the ADAPT (Air Force Data Assimilative Photospheric flux Transport) model is highlighted in this presentation. Using a magnetic flux transport model, ADAPT, we estimate the solar near-side field distribution that is used as input into empirical models for predicting F10.7(solar 10.7 cm, 2.8 GHz, radio flux), the Mg II core-to-wing ratio, and selected bands of solar far ultraviolet (FUV) and extreme ultraviolet (EUV) irradiance. Input to the ADAPT model includes the inferred photospheric magnetic field from the NISP ground-based instruments, GONG & VSM. Besides a status update regarding ADAPT and SIFT models, we will summarize the findings that: 1) the sum of the absolute value of strong magnetic fields, associated with sunspots, is shown to correlate well with the observed daily F10.7 variability (Henney et al. 2012); and 2) the sum of the absolute value of weak magnetic fields, associated with plage regions, is shown to correlate well with EUV and FUV irradiance variability (Henney et al. 2015). This work utilizes data produced collaboratively between Air Force Research Laboratory (AFRL) and the National Solar Observatory (NSO). The ADAPT model development is supported by AFRL. The input data utilized by ADAPT is obtained by NISP (NSO Integrated Synoptic Program). NSO is operated by the Association of Universities for Research in Astronomy (AURA), Inc., under a cooperative agreement with the National Science Foundation (NSF). The 10.7 cm solar radio flux data service, utilized by the ADAPT/SIFT F10.7 forecasting model, is operated by the National Research Council of Canada and National Resources Canada, with the support of the Canadian Space Agency.

    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

  3. 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.

  15. Precipitation-Based ENSO Indices

    Science.gov (United States)

    Adler, Robert; Curtis, Scott

    1998-01-01

    In this study gridded observed precipitation data sets are used to construct rainfall-based ENSO indices. The monthly El Nino and La Nina Indices (EI and LI) measure the steepest zonal gradient of precipitation anomalies between the equatorial Pacific and the Maritime Continent. This is accomplished by spatially averaging precipitation anomalies using a spatial boxcar filter, finding the maximum and minimum averages within a Pacific and Maritime Continent domain for each month, and taking differences. EI and LI can be examined separately or combined to produce one ENSO Precipitation Index (ESPI). ESPI is well correlated with traditional sea surface temperature and pressure indices, leading Nino 3.4. One advantage precipitation indices have over more conventional indices, is describing the strength and position of the Walker circulation. Examples are given of tracking the impact of ENSO events on the tropical precipitation fields.

  16. Decision making with environmental indices

    Hoag, Dana L.; Ascough, James C.; Keske-Handley, C.; Koontz, Lynne; Burk, A.R.

    2005-01-01

    Since Ott's seminal book on environmental indices (1978), the use of indices has expanded into several natural resource disciplines, including ecological studies, environmental policymaking, and agricultural economics. However, despite their increasing use in natural resource disciplines, researchers and public decision makers continue to express concern about validity of these instruments to capture and communicate multidimensional, and sometimes disparate, characteristics of research data and stakeholder interests. Our purpose is to demonstrate how useful indices can be for communicating environmental information to decision makers. We discuss how environmental indices have evolved over four stages: 1) simple; 2) compound multicriteria; 3) the impact matrix and 4) disparate stakeholder management. We provide examples of simple and compound indices that were used by policy decision makers. We then build a framework, called an Impact Matrix (IM), that comprehensively accounts for multiple indices but lets the user decide how to integrate them. The IM was shaped from the concept of a financial risk payoff matrix and applied to ecosystem risk. While the IM offers flexibility, it does not address stakeholder preferences about which index to use. Therefore, the last phase in our evolutionary ladder includes stakeholder indices to specifically address disparate stakeholder preferences. Finally, we assert that an environmental index has the potential to increase resource efficiency, since the number of decision making resources may be reduced, and hence improve upon resource productivity

    Full Text Available The assessment of urban population’s life quality implies an investigation of all factors defining it: economic, social and ecological. The development of the corresponding indicators of sustainable urban development is necessary. The majority of the cities in the world and this country show unsustainable development at present time. In the article, the world and Russian experience of development of indicators of sustainable urban development is considered. In the article, opportunities of adaptation of approaches to these indicators’ development on the basis of Human Development Index developed by United Nations Development Program and an index of Adjusted Net Savings of the World Bank for Russia are considered. The authors propose a new integrated index of sustainability for Russian cities. It is based on the concept and methodology of the Adjusted Net Savings index. In order to evaluate the sustainability of urban development taking into account economic, social, and ecological factors, the authors propose applying three corresponding sub-indexes: gross capital, expenses on human capital development, and damage from environmental pollution in the cities. In the article, the authors’ set of indicators for Russian cities is proposed. It reflects the most acute problems of sustainable urban development in Russia and the quality of life in cities; also it corresponds to Russian statistics. 21 key indicators reflecting important economic, social, and ecological urban priorities are proposed. Indicators are divided into nine groups: economic indicators; energy efficiency; transport; social and institutional indicators; air and climate; water resources; waste; especially protected natural territories; noise influence. Proposed indicators for cities allow more adequately assess trends of urbanized space shaping and quality of life

  17. Preventive Indicators for Creating Brownfields

    Directory of Open Access Journals (Sweden)

    Marija Burinskienė

    2015-05-01

    Full Text Available Although the problem of brownfields in urban territories is successfully limited, it is a negative phenomenon of a sustainable city. Moreover, the number of recently created brownfield territories has become higher than that of the regenerated ones. Such territories reduce the quality of the social and economic setting of a city as well as visually and physically affect the life quality of city residents. Unfortunately, methods for the revitalization of brownfield land have been applied to deal with the consequences of the problem rather than to limit the problem itself. The authors of the article have investigated the aspects to be avoided to not create brownfields. The indicators that enable predicting the probability of a territory becoming a brownfield have been analyzed in this paper. Countries develop and exist under different social and economic conditions. Therefore, there is no uniform and universally accepted system of indicators for brownfield prevention that can be applied in any country or city. The authors have attempted to implement a recently developed idea of indicators for prevention under Lithuanian conditions and have selected those facilitating the identification of brownfields with an aim of identifying the most significant ones warning about the potential harm from the creation of brownfields in Lithuania. The selected indicators have been grouped, taking into account social, economic, natural, building and infrastructure settings of the city and ranked by a group of experts in urban planning. The established hierarchy of indicators in the groups of urban setting has allowed the authors to select the most significant preventive indicators for brownfields. The created system of indicators could be applied in practice as a basis for monitoring pertinent data and tracking their change.

    The demand is growing for practical information on climate projections and the impacts expected in different geographical regions and different sectors. It is a challenge to transform the vast amount of data produced in climate models into relevant information for climate change impact studies. Climate indices based on climate model data can be used as means to communicate climate change impact relations. In this report a vast amount of results is presented from a multitude of indices based on different regional climate scenarios. The regional climate scenarios described in this report show many similarities with previous scenarios in terms of general evolution and amplitude of future European climate change. The broad features are manifested in increases in warm and decreases in cold indices. Likewise are presented increases in wet indices in the north and dry indices in the south. Despite the extensive nature of the material presented, it does not cover the full range of possible climate change. We foresee a continued interactive process with stakeholders as well as continued efforts and updates of the results presented in the report.

It describes the executive order of the actions that have to be done to reach to the mentioned indicator, based on the selection of the selected period of time; the types of power carriers, the weight of each carrier in the structure of the consumption and the activities where they are used. With these elements several tools are used to reach to the expected results, as the bar charts, comparative tables and indices of power intensity. The indices of energy intensity are recommended as comparative elements for the contribution to the operativity and information level, meaning that not always is necessary to tie them , if not, in some cases, may be other selected indicators that may result as qualitatives type, The Cuban enterprise system uses the model Control of Consumption and Catchment Demand of fuels and lubricants (CDA 002 of the Ministry of Economy and Planning (MEP that is used in the work and it is recommended for the organizations who apply it. The study and application of this method were made in the Company of Raw materials Recovery in an experimental form.

    Full Text Available In the paper we set the aim to determine whether phonological awareness and short-term verbal memory are indicators of a subsequent reading acquisition. The sample consisted of 194 first graders from two primary schools in Belgrade. The results of our research showed that the most significant indicator of the subsequent (unsuccessful reading was phonological awareness. The short-term verbal memory is, to a lesser extent, an indicator of the subsequent reading acquisition defined by the time needed for reading the text and by the text comprehension. Our findings offer basis for proposing that the phonological awareness assessment should be implemented into the regular procedure of assessing child's readiness for school. In this way children in need for preventive stimulation within the inclusive programme in primary schools could be identified.

  6. Website quality indicators for consumers.

    The rating tool DISCERN was designed for use by consumers without content expertise to evaluate the quality of health information. There is some evidence that DISCERN may be a valid indicator of evidence-based website quality when applied by health professionals. However, it is not known if the tool is a valid measure of evidence-based quality when used by consumers. Since it is a lengthy instrument requiring training in its use, DISCERN may prove impractical for use by the typical consumer. It is therefore important to explore the validity of other simpler potential indicators of site quality such as Google PageRank. This study aimed to determine (1) whether the instrument DISCERN is a valid indicator of evidence-based Web content quality for consumers without specific mental health training, and (2) whether Google PageRank is an indicator of website content quality as measured by an evidence-based gold standard. This was a cross-sectional survey of depression websites using consumer and health professional raters. The main outcome measures were (1) site characteristics, (2) evidence-based quality of content as measured by evidence-based depression guidelines, (3) DISCERN scores, (4) Google PageRank, and (5) user satisfaction. There was a significant association between evidence-based quality ratings and average DISCERN ratings both for consumers (r = 0.62, P = .001) and health professionals (r = 0.80, P PageRank (r = 0.59, P = .002). However, the correlation between DISCERN scores and user satisfaction was higher than the correlation between Google PageRank and user satisfaction. DISCERN has potential as an indicator of content quality when used either by experts or by consumers. Google PageRank shows some promise as an automatic indicator of quality.

    The problem of control quality of components is considered for the special case where the acceptable failure rate is low, the test costs are high and where it may be difficult or impossible to test the condition of interest directly. Based on the classical control theory and the concept...... of condition indicators introduced by Benjamin and Cornell (1970) a Bayesian approach to quality control is formulated. The formulation is then extended to the case where the quality control is based on sampling of indirect information about the condition of the components, i.e. condition indicators...

    Full Text Available Abstract Developing key performance indicators (KPIs represents one step closer to the achievement of objectives and strategic vision of the organization. They are important elements of the pathway towards performance, they evaluate and indicate the level of progress, guide the organizational strategy, they can be considered even the qualitative or quantitative expression of the execution of the strategy. Building reliable and appropriate measurement systems is one of the most difficult stage in the performance evaluation process. Such systems of management will help the executives and the management teams identify and build upon the elements that create competitive advantage and opportunities for better results.

    A rigorous method to simulate titration curves with indication using two indicator electrodes (biamperometry) is presented. Computer simulations can be carried out for reversible as well as for irreversible systems. The different parameters like the area of the individual electrodes, applied potential difference, heterogeneous rate constant, and the kinetic parameter alpha were varied and investigated as to their influence upon the shape of the titration curves. The theoretically derived effects match with the effects obtained by experiment. Considering the effects described here, it is possible to tailor the shape of the titration curve by the experimental conditions for specific applications in order to get an optimum shape at the end point of the titration.

    Faculty members' contributions to research and scholarship are measured by a variety of indices. Assessment also has become an integral part of the Accreditation Council for Pharmacy Education's accreditation process for professional programs. This review describes some of the newer indices available for faculty scholarship assessment. Recently described metrics include the h-index, m-quotient, g-index, h(2) index, a-index, m-index, r-index, ar index, and the creativity index. Of the newer scholarship metrics available, the h-index and m-quotient will likely have the most widespread application in the near future. However, there is no substitute for thoughtful peer review by experienced academicians as the primary method of research and scholarship assessment. PMID:19885080

    The Earth is an open thermodynamic system, that remains in a steady state far from the equilibrium, through energy and matter exchanges with the surrounding environment. These natural constraints, which prevent the system from maximizing its entropy, are threatened by human action and our ecosystem needs urgent protection. In this viewpoint the environmental certification was born, according to international standards ISO 14001, ISO 14040, and European Regulation EMAS. These are voluntary adhesions to a program of environmental protection by companies, administrations and organizations which, starting from the respect of the existing environmental laws and regulations, decide to further improve their environmental performance. To obtain and maintain certification of a system is necessary to apply some indicators to evaluate its environmental performance and to demonstrate its progressive improvement. Here we propose to use for this purpose the thermodynamic indicators produced from energy analysis by Odum. The case study is Montalcino city (Italy) and energy indicators are used to evaluate environmental performance of this system where exist different activities, from agricultural productions, to tourism. Results show that energy analysis could become a valid standard monitoring method for environmental certification, especially in consideration of its wide application field.

  3. Indicators of Antarctic ozone depletion

    Full Text Available An assimilated data base of total column ozone measurements from satellites has been used to generate a set of indicators describing attributes of the Antarctic ozone hole for the period 1979 to 2003, including (i daily measures of the area over Antarctica where ozone levels are below 150 DU, below 220 DU, more than 30% below 1979 to 1981 norms, and more than 50% below 1979 to 1981 norms, (ii the date of disappearance of 150 DU ozone values, 220 DU ozone values, values 30% below 1979 to 1981 norms, and values 50% below 1979 to 1981 norms, for each year, (iii daily minimum total column ozone values over Antarctica, and (iv daily values of the ozone mass deficit based on a O3<220 DU threshold. The assimilated data base combines satellite-based ozone measurements from 4 Total Ozone Mapping Spectrometer (TOMS instruments, 3 different retrievals from the Global Ozone Monitoring Experiment (GOME, and data from 4 Solar Backscatter Ultra-Violet (SBUV instruments. Comparisons with the global ground-based Dobson spectrophotometer network are used to remove offsets and drifts between the different data sets to produce a global homogeneous data set that combines the advantages of good spatial coverage of satellite data with good long-term stability of ground-based measurements. One potential use of the derived indices is detection of the expected recovery of the Antarctic ozone hole. The suitability of the derived indicators to this task is discussed in the context of their variability and their susceptibility to saturation effects which makes them less responsive to decreasing stratospheric halogen loading. It is also shown that if the corrections required to match recent Earth Probe TOMS measurements to Dobson measurements are not applied, some of the indictors are affected so as to obscure detection of the recovery of the Antarctic ozone hole.

  4. Construction and demolition waste indicators.

    The construction industry is one of the biggest and most active sectors of the European Union (EU), consuming more raw materials and energy than any other economic activity. Furthermore, construction waste is the commonest waste produced in the EU. Current EU legislation sets out to implement construction and demolition waste (CDW) prevention and recycling measures. However it lacks tools to accelerate the development of a sector as bound by tradition as the building industry. The main objective of the present study was to determine indicators to estimate the amount of CDW generated on site both globally and by waste stream. CDW generation was estimated for six specific sectors: new residential construction, new non-residential construction, residential demolition, non-residential demolition, residential refurbishment, and non-residential refurbishment. The data needed to develop the indicators was collected through an exhaustive survey of previous international studies. The indicators determined suggest that the average composition of waste generated on site is mostly concrete and ceramic materials. Specifically for new residential and new non-residential construction the production of concrete waste in buildings with a reinforced concrete structure lies between 17.8 and 32.9 kg m(-2) and between 18.3 and 40.1 kg m(-2), respectively. For the residential and non-residential demolition sectors the production of this waste stream in buildings with a reinforced concrete structure varies from 492 to 840 kg m(-2) and from 401 to 768 kg/m(-2), respectively. For the residential and non-residential refurbishment sectors the production of concrete waste in buildings lies between 18.9 and 45.9 kg/m(-2) and between 18.9 and 191.2 kg/m(-2), respectively.

    There are two types of fat distribution in obese subjects. The abdominal, superior, android or apple shaped and the gluteo-femoral, gynecoid, inferior or pear shaped. In the former, fat is accumulated in the abdomen and in the latter, in the gluteal region. The superior distribution is associated with a higher risk of cardiovascular diseases. Among anthropometric measurements of fat distribution, the ratio between waist circumference measured at the level of the navel and hip circumference, measured at the level of greater trochanters, is the best indicator. Using the cutoff points of 0.8 for women and 1 for men, it has a good correlation with visceral fat.

    Full Text Available Abstract Background Vertigo and dizziness are symptoms which are reported frequently in clinical practice. We aimed to develop diagnostic indices for four prevalent vertiginous diseases: benign paroxysmal positional vertigo (BPPV, Menière's disease (MD, vestibular migraine (VM, and phobic postural vertigo (PPV. Methods Based on a detailed questionnaire handed out to consecutive patients presenting for the first time in our dizziness clinic we preselected a set of seven questions with desirable diagnostic properties when compared with the final diagnosis after medical workup. Using exact logistic regression analysis diagnostic scores, each comprising of four to six items that can simply be added up, were built for each of the four diagnoses. Results Of 193 patients 131 questionnaires were left after excluding those with missing consent or data. Applying the suggested cut-off points, sensitivity and specificity were 87.5 and 93.5% for BPPV, 100 and 87.4% for MD, 92.3 and 83.7% for VM, 73.7 and 84.1% for PPV, respectively. By changing the cut-off points sensitivity and specificity can be adjusted to meet diagnostic needs. Conclusions The diagnostic indices showed promising diagnostic properties. Once further validated, they could provide an ease to use and yet flexible tool for screening vertigo in clinical practice and epidemiological research.

    2011-01-01

    The current study objective was to compare blood platelet indices in full-term small-for-gestational-age newborns (SGA) and full-term appropriate-for-gestational-age newborns (AGA). We introduced to our study 61 SGA newborns (31 females and 30 males) and 70 eutrophic infants (32 females and 38 males). The SGA newborns were divided into two groups: those weighing less than the 5th centile: 35 infants (16 females and 19 males) and those between the 5th and 10th centiles: 26 infants (15 females and 11 males). Platelet indices were estimated in blood samples collected from the umbilical artery. SGA demonstrated a decreased count of blood platelets (238×103/μ) as compared with AGA (286×103/μL), p=0.0001. Platelet hematocrit (PTC) also showed differences in both groups (SGA=0.19% vs. AGA=0.22%; p=0.0005). Mean platelet volume (MPV) was higher in SGA (8.25fl) as compared with AGA (7.84fl); p=0.008. Large platelet count (LPLT) was higher in AGA 6.26% vs. SGA=4.75%; p=0.01. Platelet distribution width (PDW) was found to be nearly the same (SGA=47%, AGA=46%). PDW was higher in SGA newborns SGA infants between the 5th and 10th centiles (52%); p=0.008. A decreased blood platelet count, platelet hematocrit and large metabolically active platelet count, which in addition to reduced synthesis and excessive consumption of coagulation factors in states of hiperclotting is characteristic of IUGR, enhances the possibility of bleeding complications and increases the risk of infections. From a clinical point of view, it is important to take into consideration the degree of intrauterine hypotrophy during the evaluation of hemostatic disorders.

  12. Biological indicators of chrysotile exposure.

    Science.gov (United States)

    Case, B W

    1994-08-01

    Chrysotile asbestos is retained in lung tissue, where it may be used as a marker of exposure. Studies include analysis of sputum and bronchoalveolar lavage fluid, but principally lung parenchyma from autopsy or surgically resected specimens. Asbestos bodies form on chrysotile fibres but are generally not a good indicator of human exposure to chrysotile because of their greater probability of formation on amphiboles. Chrysotile fibre analyses in lung have advantages and limitations. Chrysotile concentration is related to the level of environmental and occupational exposure, but in the latter situation owing to deposition, fibre alteration and clearance cumulative exposure and interval between end-exposure and death clearly affect results. Autopsy case series are biased toward increased proportions of asbestos-related diseases as compared to epidemiological cohort data. Analytical problems include potential contamination by chrysotile at autopsy, from fixatives, from post-fixative processing and in the analytical laboratory itself. These may have greatest effect in studies of individuals with low exposure, for tissue other than lung, and for short chrysotile fibres. Selection of control subjects should be contemporaneous with that of cases, and control subjects should fully reflect the hospital population at the time of case death. Limited data are available on fibre analysis in pleural tissue. More are needed. Issues requiring attention include avoidance of contamination, selection of controls, and sample site selection (parietal pleura, or tumour or plaque). For mesothelioma, two case-control studies of lung fibre burden show the principal relationship to be with long amphiboles, but some methodological problems exist. Lung cancer shows no such fibre-type differences. Asbestosis seems to be associated with long-fibre chrysotile and tremolite in one study and short fibres in others. Overall, lung retained dose is a useful indicator of chrysotile exposure if used

  13. 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

  14. Indicators of Evidence for Bioequivalence

    Directory of Open Access Journals (Sweden)

    Stephan Morgenthaler

    2016-08-01

    Full Text Available Some equivalence tests are based on two one-sided tests, where in many applications the test statistics are approximately normal. We define and find evidence for equivalence in Z-tests and then one- and two-sample binomial tests as well as for t-tests. Multivariate equivalence tests are typically based on statistics with non-central chi-squared or non-central F distributions in which the non-centrality parameter λ is a measure of heterogeneity of several groups. Classical tests of the null λ ≥ λ 0 versus the equivalence alternative λ < λ 0 are available, but simple formulae for power functions are not. In these tests, the equivalence limit λ 0 is typically chosen by context. We provide extensions of classical variance stabilizing transformations for the non-central chi-squared and F distributions that are easy to implement and which lead to indicators of evidence for equivalence. Approximate power functions are also obtained via simple expressions for the expected evidence in these equivalence tests.

  15. Mute swans: Natural (?) environmental indicators

    Day, D.; Perry, Matthew C.

    2004-01-01

    The rapid expansion of the Chesapeake Bay's population of feral mute swans (Cygnus olar), coupled with a dramatic Bay-wide decline in submerged aquatic vegetation (SAV), has fueled much of the current debate surrounding the need for a management plan to protect the aquatic food resources that are critical to many species native to the Bay. Crucial to this decision process is a sound understanding of the ecological ramifications of having the year-round presence of a large, nonnative, aquatic herbivore on the Bay. Ultimately, this will require a quantitative assessment of the ecological harm currently posed by mute swans before a biologically defensible management strategy can be developed. Unfortunately, very little new information specific to the Bay's mute swan population has been gathered since Reese first studied them in the late 1960s and 1970s. While the debate over what to do about the rapidly expanding mute swan population continues, there is much that can be gained from study of this beautiful intruder. Several recent studies of the feeding habits of mute swans have shown that mutes can provide a unique barometer, or indicator, of environmental conditions. Because of their reliance on SAV as a primary food source, monitoring the density of swans utilizing a particular area can give some indication of the status of the area's grass beds. This phenomenon was clearly demonstrated during the summer of 1999 when there was a dramatic decline in the number of swans observed around the Eastern Neck NWR, a traditional population stronghold. The shift in bird use was precipitated by a rapid, large-scale collapse of the area's aquatic grass beds, possibly the result of a prolonged drought. During the winter of 2000/2001, a similar ecological assessment was conducted by comparing body weights of swans collected from Tangier Sound, an area with relatively abundant grass beds, and swans from the waters adjacent to Eastern Neck Island. Swans weights tended to reflect the

    Full Text Available Objective: To review of concepts and actions that aim to analyze the effects of internationalization of science and education, with emphasis in the medical field and its basement in development policies adopted by nations, exploring the potential for international interdisciplinary cooperation of each laboratory, department, university or institute. Method: Search of indicators to assess the degree of internationalization of universities and research institutes in several interconnected levels: organizational, regional, sectoral and global, and policy-making in science, technology innovation and higher education. Result: Scientific research is still carried out individually, but is now much more closely integrated with other social processes. The scientist is no longer a stranger who is allowed to surrender to his hobby to do what it wants. Internationalization of research and medical education, although it is among the topics of greatest need, as the globalized world, is difficult activity to be assessed. The leaders seem to have understood that the knowledge societies, leading to economic policy based on knowledge, can result in economic and social progress of nations. This fact has motivated increasingly the incentive to actions aimed at addressing global problems (eg health, climate change by funding research that generates new knowledge. Conclusion: The consensus is that the internationalization of science is desirable and necessary for the sustainable development of nations. However it cannot be done only by encouraging and promoting the outward students and researchers abroad. It is necessary, in addition, offer conditions to foreign researchers and students teachers to work in collaboration with Brazilian and raise the country to international scientific standards.

  17. Eosinophilic esophagitis: indications for treatment.

    Science.gov (United States)

    Straumann, Alex

    2014-01-01

    At present, it is still debated whether the focus of treatment in eosinophilic esophagitis (EoE) should be directed toward a symptomatic or histological response, or even toward a combination of both. This question cannot be answered as long as we have no solid data evaluating the long-term consequences of untreated symptoms and untreated inflammation. Nevertheless, today there are at least three established reasons to treat patients with clinically and histologically active EoE. First, dysphagia has a substantial negative impact on the patient's daily life. Despite the fact that patients often cope with this symptom and accept even marked restrictions in their nutritional habits, they usually experience a marked enhancement in quality of life under treatment. Second, untreated EoE harbors the risk of long-lasting food impactions. There is evidence that this unpleasant, unforeseeable and even risky incident can be prevented by efficient treatment of the eosinophilic inflammation. Third, it has been demonstrated in several clinical studies as well as in animal models that unbridled eosinophilic inflammation leads to a so-called remodeling of the esophagus with wall thickening, stiffness of the organ and stricture. Prevention of esophageal damage caused by tissue remodeling is therefore another reason to strongly advocate a consequential treatment. Finally, there is increasing evidence that untreated EoE might be a risk factor for acute infection of the esophagus with herpes simplex virus (HSV), leading to a severe ulcerative and extremely painful esophagitis. Prevention of HSV esophagitis might therefore be a fourth indication for treating EoE. 2014 S. Karger AG, Basel.

  18. Do Scientometric Indices Require Revision?

    that in a scientific domain, more cited articles are in a higher scientific rank, while there are articles that are analyzed and reviewed by researchers due to presenting a contradictory subject, and are frequently cited in spite of their inappropriate scientific value, although these citations are not indicative of their higher quality. The impact factor of journals can also make the comparison and ranking of researchers problematic. It is burdensome to compare two researchers with equal h index but different impact factor of journals in which they have published their papers. However, it should be noted that there are differences between two researchers with similar h index in terms of scientific life, number of publications, total number of citations and impact factor of journals in which their articles have been published. Further, the authors of an article do not have the same role and collaboration in publishing the paper. Imagine a researcher with 100 articles and h=15 has been the corresponding author only in 5 articles, but coauthor in the rest of articles. It seems that scientific index for the corresponding author of each article is more important than allocating similar credits to all authors. Nowadays, h index is extensively used to measure the scientific status of researchers, journals, departments and universities. In some academic centers, however, it is incorrectly used to compare the researchers in different majors. Since the introduction of this index, various variants have been prompted upon it; thereby, pre¬senting different variations such as a, g, m and r indices (3. Although, h index apparently differentiates the prominent researchers from those who have merely published many papers, it cannot reveal a perfect view of the scientific output of a researcher. Application of a scientometric criterion alone cannot determine the precise and valid scientific rank of the researchers. Thus, a proper combination of criteria seems necessary. Furthermore

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

    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.

  10. An efficient compression scheme for bitmap indices

    Energy Technology Data Exchange (ETDEWEB)

    Wu, Kesheng; Otoo, Ekow J.; Shoshani, Arie

    2004-04-13

    When using an out-of-core indexing method to answer a query, it is generally assumed that the I/O cost dominates the overall query response time. Because of this, most research on indexing methods concentrate on reducing the sizes of indices. For bitmap indices, compression has been used for this purpose. However, in most cases, operations on these compressed bitmaps, mostly bitwise logical operations such as AND, OR, and NOT, spend more time in CPU than in I/O. To speedup these operations, a number of specialized bitmap compression schemes have been developed; the best known of which is the byte-aligned bitmap code (BBC). They are usually faster in performing logical operations than the general purpose compression schemes, but, the time spent in CPU still dominates the total query response time. To reduce the query response time, we designed a CPU-friendly scheme named the word-aligned hybrid (WAH) code. In this paper, we prove that the sizes of WAH compressed bitmap indices are about two words per row for large range of attributes. This size is smaller than typical sizes of commonly used indices, such as a B-tree. Therefore, WAH compressed indices are not only appropriate for low cardinality attributes but also for high cardinality attributes.In the worst case, the time to operate on compressed bitmaps is proportional to the total size of the bitmaps involved. The total size of the bitmaps required to answer a query on one attribute is proportional to the number of hits. These indicate that WAH compressed bitmap indices are optimal. To verify their effectiveness, we generated bitmap indices for four different datasets and measured the response time of many range queries. Tests confirm that sizes of compressed bitmap indices are indeed smaller than B-tree indices, and query processing with WAH compressed indices is much faster than with BBC compressed indices, projection indices and B-tree indices. In addition, we also verified that the average query response time

  12. Connecting Indicators with land degradation and desertification

    Science.gov (United States)

    Kosmas, C.

    2012-04-01

    A series of 72 selected candidate indicators corresponding to the physical environment, social, economic, and land management characteristics were defined in 1672 field sites located in 17 study sites in the Mediterranean and eastern Europe, Latin America, Africa, and Asia. The selected indicators refer to specific farm characteristics such as family status, land tenure, present and previous types of land use, period of existing type of land use, soil depth, slope gradient, tillage operations, tillage depth and direction, etc., as well as to regional characteristics such as annual rainfall, rain seasonality, water availability, water quality and quantity, rate of land abandonment, rate of burned area, etc. Based on existing geo-referenced database, classes have been designated for each indicator and presented in a tabulated form. Weighing indices have been assigned to each class based on existing research or empirically assessing the importance to land degradation and desertification. Various processes or causes related to land degradation and desertification important for the study sites have been studied and the most relevant indicators have been defined. Questionnaires for each process or cause have been prepared and data were collected at field site level in collaboration with land users. The obtained data were statistically analyzed to identify the most important indicators related to each process or cause affecting land degradation and desertification. The analyses have shown that indicators may be widely, even globally, used for assessing the various land degradation and desertification processes or causes at field level. Of course, some indicators related to agriculture, social, and institutional characteristics in some cases show trends that are opposite to what happens in other study sites. These trends can be explained by further investigation including other indicators or processes affecting land degradation and desertification that it was not possible

    2012-01-01

    Objective Promoting mental health and preventing mental health problems are important tasks for international organizations and nations. Such goals entail the establishment of active information networks and effective systems and indicators to assess the mental health of populations. This being said, there is a need in Korea develop ways to measure the state of mental health in Korea. Methods This paper reviews the mental health indicator development policies and practices of seven organizations, countries, and regions: WHO, OECD, EU, United States, Australia, UK, and Scotland. Using Delphi method, we conducted two surveys of mental health indicators for experts in the field of mental health. The survey questionnaire included 5 domains: mental health status, mental health factor, mental health system, mental health service, and quality of mental health services. We considered 124 potential mental health indicators out of more than 600 from indicators of international organizations and foreign countries. Results We obtained the top 30 mental health indicators from the surveys. Among them, 10 indicators belong to the mental health system. The most important five mental health indicators are suicide rate, rate of increase in mental disorder treatment, burden caused by mental disorders, adequacy of identifying problems of mental health projects and deriving solutions, and annual prevalence of mental disorders. Conclusion Our study provides information about the process for indicator development and the use of survey results to measure the mental health status of the Korean population. The aim of mental health indicator development is to improve the mental health system by better grasping the current situation. We suggest these mental health indicators can monitor progress in efforts to implement reform policies, provide community services, and involve users, families and other stakeholders in mental health promotion, prevention, care and rehabilitation.

    2003-01-01

    To develop and use drug use indicators for epilepsy management. Descriptive prospective (outpatient) and retrospective (inpatient) drug use indicator survey. Parirenyatwa Hospital epilepsy clinic and medical wards. Random sample of 35 cases of status epilepticus and a prospective series of 31 patients attending the epilepsy clinic. Indicators of drug use and patient care were developed and measured against national standard treatment guidelines (EDLIZ). Stock levels of all anti epileptic drugs (AEDs) were determined. Adherence to EDLIZ; utility of indicator measures. For inpatients, average length of hospital stay was 8.7 days, with 60.0% adherence to EDLIZ. Less than half of the patients had an EEG performed and one third had an AED blood level measured. On discharge, patients were prescribed an average of 1.1 AEDs. Outpatient indicators showed good adherence to EDLIZ (89.2%) and an average of 1.2 AEDs drugs per prescription. Only 56.4% of prescribed drugs were actually dispensed. Most knew the dose and frequency of their medication but only 71.4% were aware of the expected duration of therapy. The use of the indicators provided a snapshot of epilepsy management and indicated that problems may exist in the use of EEGs and in drug supply at Parirenyatwa Hospital. Sensitivity of the indicators to change and across levels of care still needs to be determined.

    Daniël B van Schalkwijk

    Full Text Available BACKGROUND: Cardiovascular disease risk increases when lipoprotein metabolism is dysfunctional. We have developed a computational model able to derive indicators of lipoprotein production, lipolysis, and uptake processes from a single lipoprotein profile measurement. This is the first study to investigate whether lipoprotein metabolism indicators can improve cardiovascular risk prediction and therapy management. METHODS AND RESULTS: We calculated lipoprotein metabolism indicators for 1981 subjects (145 cases, 1836 controls from the Framingham Heart Study offspring cohort in which NMR lipoprotein profiles were measured. We applied a statistical learning algorithm using a support vector machine to select conventional risk factors and lipoprotein metabolism indicators that contributed to predicting risk for general cardiovascular disease. Risk prediction was quantified by the change in the Area-Under-the-ROC-Curve (ΔAUC and by risk reclassification (Net Reclassification Improvement (NRI and Integrated Discrimination Improvement (IDI. Two VLDL lipoprotein metabolism indicators (VLDLE and VLDLH improved cardiovascular risk prediction. We added these indicators to a multivariate model with the best performing conventional risk markers. Our method significantly improved both CVD prediction and risk reclassification. CONCLUSIONS: Two calculated VLDL metabolism indicators significantly improved cardiovascular risk prediction. These indicators may help to reduce prescription of unnecessary cholesterol-lowering medication, reducing costs and possible side-effects. For clinical application, further validation is required.

    A multifunctional smart coating for the autonomous detection, indication, and control of corrosion is been developed based on microencapsulation technology. This paper summarizes the development, optimization, and testing of microcapsules specifically designed for early detection and indication of corrosion when incorporated into a smart coating. Results from experiments designed to test the ability of the microcapsules to detect and indicate corrosion, when blended into several paint systems, show that these experimental coatings generate a color change, indicative of spot specific corrosion events, that can be observed with the naked eye within hours rather than the hundreds of hours or months typical of the standard accelerated corrosion test protocols..

  18. Water quality indicators: bacteria, coliphages, enteric viruses.

    Science.gov (United States)

    Lin, Johnson; Ganesh, Atheesha

    2013-12-01

    Water quality through the presence of pathogenic enteric microorganisms may affect human health. Coliform bacteria, Escherichia coli and coliphages are normally used as indicators of water quality. However, the presence of above-mentioned indicators do not always suggest the presence of human enteric viruses. It is important to study human enteric viruses in water. Human enteric viruses can tolerate fluctuating environmental conditions and survive in the environment for long periods of time becoming causal agents of diarrhoeal diseases. Therefore, the potential of human pathogenic viruses as significant indicators of water quality is emerging. Human Adenoviruses and other viruses have been proposed as suitable indices for the effective identification of such organisms of human origin contaminating water systems. This article reports on the recent developments in the management of water quality specifically focusing on human enteric viruses as indicators.

The level of glucose in saliva was detected by glucose oxydase technique using analyzer "EXAN-G". The protein in saliva was detected by biuretic technique. The correlation between acoustic indicator of saliva and analyzed indicators of saliva was established.

  1. Driver competence performance indicators using OTMR

    Energy Technology Data Exchange (ETDEWEB)

    Hassan EL Rashidy, R.A.

    2016-07-01

    The current practice for assessing driver competence performance is in-cab riding by driver managers. However, this paper investigates whether real-world driving data extracted from on-train monitoring recorders data (OTMR) can be used to assess the driver performance. A number of indicators were used to evaluate the drivers’ performance. These include: their use of the emergency bypass switch, the driver's reminder appliance as well as the driver’s reaction time. A study case illustrated the applicability of OTMR data to estimate the proposed indicators, which suggests that the indicators can be useful in the driver management system in addition to the current indicators. Furthermore, the proposed indicators could be used to tailor the driver training schemes up to their individual needs and evaluate their effectiveness. They could even be used for improving driver competence performance and reducing crash involvement by revealing potentially detrimental driving performance. (Author)

    Traditionally, the microbiological quality of waters has been measured by the analysis of indicator microorganisms. The article reviews the sanitary significance of traditional indicators of faecal contamination (total coliforms, faecal coliforms and faecal streptococci) and points out their limits. For some characteristics Escherichia coli may be considered a more useful indicator then faecal coliforms and recently it has been included in all recent laws regarding fresh, marine and drinking water. A clearer taxonomic definition of faecal streptococci evidenced the difficulty into defining a specific standard methodology of enumeration and suggested the more suitable role of enterococci as indicator microorganisms. Several current laws require the detection of enterococci. The resistance of Clostridium perfringens spores may mean that they would serve as a useful indicator of the sanitary quality of sea sediments.

  5. An Entangled Model for Sustainability Indicators.

    Directory of Open Access Journals (Sweden)

    Pável Vázquez

    Full Text Available Nowadays the challenge for humanity is to find pathways towards sustainable development. Decision makers require a set of sustainability indicators to know if the sustainability strategies are following those pathways. There are more than one hundred sustainability indicators but they differ on their relative importance according to the size of the locality and change on time. The resources needed to follow these sustainability indicators are scarce and in some instances finite, especially in smaller regions. Therefore strategies to select set of these indicators are useful for decision makers responsible for monitoring sustainability. In this paper we propose a model for the identification and selection of a set of sustainability indicators that adequately represents human systems. In developing this model, we applied evolutionary dynamics in a space where sustainability indicators are fundamental entities interconnected by an interaction matrix. we used a fixed interaction that simulates the current context for the city of Cuernavaca, México as an example. We were able to identify and define relevant sets indicators for the system by using the Pareto principle. In this case we identified a set of sixteen sustainability indicators with more than 80% of the total strength. This set presents resilience to perturbations. For the Tangled Nature framework we provided a manner of treating different contexts (i.e., cities, counties, states, regions, countries, continents or the whole planet, dealing with small dimensions. This model provides decision makers with a valuable tool to select sustainability indicators set for towns, cities, regions, countries, continents or the entire planet according to a coevolutionary framework. The social legitimacy can arise from the fact that each individual indicator must be selected from those that are most important for the subject community.

  6. Comparison of UTCI to selected thermal indices

    2012-05-01

    Over the past century more than 100 indices have been developed and used to assess bioclimatic conditions for human beings. The majority of these indices are used sporadically or for specific purposes. Some are based on generalized results of measurements (wind chill, cooling power, wet bulb temperature) and some on the empirically observed reactions of the human body to thermal stress (physiological strain, effective temperature). Those indices that are based on human heat balance considerations are referred to as "rational indices". Several simple human heat balance models are known and are used in research and practice. This paper presents a comparative analysis of the newly developed Universal Thermal Climate Index (UTCI), and some of the more prevalent thermal indices. The analysis is based on three groups of data: global data-set, synoptic datasets from Europe, and local scale data from special measurement campaigns of COST Action 730. We found the present indices to express bioclimatic conditions reasonably only under specific meteorological situations, while the UTCI represents specific climates, weather, and locations much better. Furthermore, similar to the human body, the UTCI is very sensitive to changes in ambient stimuli: temperature, solar radiation, wind and humidity. UTCI depicts temporal variability of thermal conditions better than other indices. The UTCI scale is able to express even slight differences in the intensity of meteorological stimuli.

    A Catalogue of Marine Biodiversity Indicators was developed with the aim of providing the basis for assessing the environmental status of the marine ecosystems. Useful for the implementation of the Marine Strategy Framework Directive (MSFD), this catalogue allows the navigation of a database of indicators mostly related to biological diversity, non-indigenous species, food webs, and seafloor integrity. Over 600 indicators were compiled, which were developed and used in the framework of different initiatives (e.g., EU policies, research projects) and in national and international contexts (e.g., Regional Seas Conventions, and assessments in non-European seas). The catalogue reflects the current scientific capability to address environmental assessment needs by providing a broad coverage of the most relevant indicators for marine biodiversity and ecosystem integrity. The available indicators are reviewed according to their typology, data requirements, development status, geographical coverage, relevance to habitats or biodiversity components, and related human pressures. Through this comprehensive overview, we discuss the potential of the current set of indicators in a wide range of contexts, from large-scale to local environmental programs, and we also address shortcomings in light of current needs. Developed by the DEVOTES Project, the catalogue is freely available through the DEVOTool software application, which provides browsing and query options for the associated metadata. The tool allows extraction of ranked indicator lists best fulfilling selected criteria, enabling users to search for suitable indicators to address a particular biodiversity component, ecosystem feature, habitat, or pressure in a marine area of interest. This tool is useful for EU Member States, Regional Sea Conventions, the European Commission, non-governmental organizations, managers, scientists, and any person interested in marine environmental assessment. It allows users to build

    Full Text Available Environmental indicators promote the eco-efficient development of companies, as demonstrated in earlier study. This study builds on a previously developed model and inventory tools for industryspecific environmental indicators for the graphic arts industry. This study is based on case studies from 14 newspaper companies with experience of the use of these industry-specific environmental indicators in actual production.This paper presents data on industry-specific environmental indicators for the newspaper industry. The data describes the average situation and the range of values for the indicators in 14 environmentally aware newspaper companies in Sweden in 2001. The data is also grouped so as to illustrate average values for various classes:Newspaper companies with printing facilities.Newspaper companies with no printing facilities.Newspaper printing companies.In addition, a preliminary comparison has been carried out using equivalent data for the commercial printing industry.The indicators calculated for each specific company, together with average values for these indicators, have been used to identify areas for action for the various companies and to formulate action plans. The aim of this is to promote more eco-efficient activities. The study also summarizes measures already implemented at the various companies.The use of indicators within these companies has been linked with the current and predicted future eed to communicate environmental issues. Financial and social aspects have been considered to a limited extent in the study in order to put forward the concept of sustainable development in the newspaper industry in Sweden.

    1996-08-01

    Site characterization is an important prerequisite of risk assessment and remediation strategies. Evaluation of the health effects of groundwater and soil contamination depends on the adequate analysis of spatial heterogeneity, exceedance levels, and uncertainties. In this work we formulate and calculate stochastic indicators that provide a rigorous characterization of exposure levels in sites with heterogeneous contaminant distributions and offer valuable information for a cost-effective cleanup analysis. These site indicators are general and can be used for different types and distributions of groundwater and soil contaminants. Important properties of the stochastic indicators are examined which can evaluate the potential for contamination at large scales, and improve understanding of threatened and damaged ecosystems. Analytically tractable formulas are derived that allow the practical estimation of site indicators on the basis of experimental data. Scale and modeling effects on contaminant level analysis are examined in terms of the stochastic indicators. Site cleanup costs depend directly on inferred characteristics of the stochastic indicators, which thus can play an important role in waste site management. Applications are discussed that offer insight regarding certain aspects of stochastic site characterization. Analytical methods of site characterization are compared to numerical simulations. It is shown that the latter can provide a practical alternative to the former, but they could lead to inaccurate results if they are not interpreted carefully.

  13. Reliability and usability of tourism climate indices

    2016-04-01

    Full Text Available Abstract Tourism climate indices (TCI are commonly used to describe the climate conditions suitable for tourism activities, from the planning, investment or daily operations perspectives. A substantial amount of research has been carried out, in particular with respect to new indices formulae adapted to specific tourism products, and parameters and their weighting, taking into account surveys on the stated preferences of tourists, especially in terms of comfort. This paper illustrates another field of research, which seeks to better understand the different sources of uncertainty associated with indices. Indeed, slight differences in formula thresholds, variations in computation methods, and also the use of multimodel ensembles create nuances that affect the ways in which indices projections are usually presented. Firstly, we assess the impact of differences in preference surveys on the definition of indices thresholds, in particular for thermal comfort. Secondly, we compare computation methods for France, showing the need to better specify detailed data sources and their use to ensure the comparability of results. Thirdly, using multimodel ensembles for the Mediterranean basin, we assess the uncertainty inherent in long-term projections, which are used in modelling the economic impact of climate change. This paper argues in favour of a more cautious use of tourism comfort indices, with more consideration given to the robustness of data (validation, debiasing, uncertainty assessment, etc. and users’ needs, from the climate services perspective.

    2015-12-01

    Full Text Available The purpose of the article is the interregional analysis of human potential. In comparison with the quality of life of the population, the quality of population itself is studied far less. The article presents an expanded characteristic of human potential in seven directions: economic activity, demographic processes, physical health, cultural potential, social health, educational potential and the attitude of the population to the environment. On the basis of statistics for 2008–2012 years, 63 indicators of human potential for all directions are selected. In the final result, the correlation analysis has led to the substantiation of the system of indicators consisting of 10 indicators. Three economic and seven social indicators characterizing human potential are included into this system. On the basis of the indicators by means of hierarchical agglomerative methods of cluster analysis, a classification of the Russian regions is carried out in two versions: with economic indicators and without them. The result of the calculations is a stable temporal typology of regions by indicators of human potential covering 74.4 % of the population of Russia. The article provides a substantial interpretation of dividing regions into groups, identifies the strengths and weaknesses of each cluster, shows the specific features of the regions included into the clusters. The obtained results can be used in the development of measures for the reduction of the interregional inequality in terms of human potential. It is possible to define what measures can be effective by studying the strategic directions of the development of regions in the cluster which is the most successful regarding the characteristics of human potential.

    Full Text Available The article shows the process of constructing the project deviations indicator model. It based on a conceptual model of project deviations integrated management (PDIM. During the project different causes (such as risks, changes, problems, crises, conflicts, stress lead to deviations of integrated project indicators - time, cost, quality, and content. For a more detailed definition of where in the project deviations occur and how they are dangerous for the whole project, it needs to develop an indicative model of project deviations. It allows identifying the most dangerous deviations that require PDIM. As a basis for evaluation of project's success has been taken famous model IPMA Delta. During the evaluation, IPMA Delta estimated project management competence of organization in three modules: I-Module ("Individuals" - a self-assessment personnel, P-module ("Projects" - self-assessment of projects and/or programs, and O-module ("Organization" - used to conduct interviews with selected people during auditing company. In the process of building an indicative model of deviations in the project, the first step is the assessment of project management in the organization by IPMA Delta. In the future, built cognitive map and matrix of system interconnections of the project, which conducted simulations and built a scale of deviations for the selected project. They determined a size and place of deviations. To identify the detailed causes of deviations in the project management has been proposed to use the extended system of indicators, which is based on indicators of project management model Project Excellence. The proposed indicative model of deviations in projects allows to estimate the size of variation and more accurately identify the place of negative deviations in the project and provides the project manager information for operational decision making for the management of deviations in the implementation of the project

  16. Identifying novel drug indications through automated reasoning.

    Directory of Open Access Journals (Sweden)

    Luis Tari

    Full Text Available With the large amount of pharmacological and biological knowledge available in literature, finding novel drug indications for existing drugs using in silico approaches has become increasingly feasible. Typical literature-based approaches generate new hypotheses in the form of protein-protein interactions networks by means of linking concepts based on their cooccurrences within abstracts. However, this kind of approaches tends to generate too many hypotheses, and identifying new drug indications from large networks can be a time-consuming process.In this work, we developed a method that acquires the necessary facts from literature and knowledge bases, and identifies new drug indications through automated reasoning. This is achieved by encoding the molecular effects caused by drug-target interactions and links to various diseases and drug mechanism as domain knowledge in AnsProlog, a declarative language that is useful for automated reasoning, including reasoning with incomplete information. Unlike other literature-based approaches, our approach is more fine-grained, especially in identifying indirect relationships for drug indications.To evaluate the capability of our approach in inferring novel drug indications, we applied our method to 943 drugs from DrugBank and asked if any of these drugs have potential anti-cancer activities based on information on their targets and molecular interaction types alone. A total of 507 drugs were found to have the potential to be used for cancer treatments. Among the potential anti-cancer drugs, 67 out of 81 drugs (a recall of 82.7% are indeed known cancer drugs. In addition, 144 out of 289 drugs (a recall of 49.8% are non-cancer drugs that are currently tested in clinical trials for cancer treatments. These results suggest that our method is able to infer drug indications (original or alternative based on their molecular targets and interactions alone and has the potential to discover novel drug indications for

    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.

    2008-11-01

    The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.

    The concept of vulnerability is delimited by dynamic social and multigenerational processes involving at least three dimensions: exposure to risk trajectories, internal and external capabilities of reaction and possibilities of adaptation based on both the intensity of risk and the resilience of people. In order to identify and describe the synthetic indices of vulnerability, there was an integrative literature review. We consulted free access articles indexed in the following databases: BioMed, Bireme, PubMed, Reldalyc, SciELO and Web of Science; and we used controlled descriptors in English and Portuguese for all time slots available with selection and analysis of 47 studies that reported results of 23 synthetic indices of vulnerability. The results showed that the synthetic indices of vulnerability address four themes: social determinants of health; environmental and climatic conditions; family and course of life; territories and specific geographic areas. It was concluded that the definition of the components and indicators, as well as the methodologies adopted for the construction of synthetic indices need to be evaluated by means of the limitations and advantages of reporting the vulnerability through summary measures in policy formulation and decision-making aimed at human development.

    Full Text Available Four East Asian winter monsoon (EAWM indices are compared in this paper. In the research periods, all the indices show similar interannual and decadal-interdecadal variations, with predominant periods centering in 3–4 years, 6.5 years and 9–15 years, respectively. Besides, all the indices show remarkable weakening trends since the 1980s. The correlation coefficient of each two indices is positive with a significance level of 99%. Both the correlation analyses and the composites indicate that in stronger EAWM years, the Siberian high and the higher-level subtropical westerly jet are stronger, and the Aleutian low and the East Asia trough are deeper. This circulation pattern is favorable for much stronger northwesterly wind and lower air temperature in the subtropical regions of East Asia, while it is on the opposite in weaker EAWM years. Besides, EAWM can also exert a remarkable leading effect on the summer monsoon. After stronger (weaker EAWM, less (more summer precipitation is seen over the regions from the Yangtze River valley of China to southern Japan, while more (less from South China Sea to the tropical western Pacific.

  1. Ciphering Indicator approaches and user awareness

    Full Text Available One of the fundamental mobile phone security problems in GSM is the absence of base station authentication, which allows man-in-the-middle attacks. During such attacks, a third party activates a fake base station, which acts as a bypass to the network, thus switching off the encryption and intercepting the user’s communications. 3G mobile networks enforce mutual authentication but this can be circumvented if the 3G band is jammed by the attacker, forcing the phone to connect using GSM. GSM and newer standards provide a user alert indicating that the encryption has been switched off, which is called a Ciphering Indicator. In the present paper, different approaches followed by various manufacturers concerning the Ciphering Indicator are investigated. A total of 38 different mobile phones ranging from old to new and from simple to smart-phones that were produced by 13 different manufacturers were intercepted using a GSM testing device in order to document their reactions. Four approaches were identified with some manufacturers choosing not to implement the feature at all. It was also found that in the cases in which the feature was actually implemented, no universal indication was used and it was seldom documented in the phones’ manuals. User awareness regarding the Ciphering Indicator and security issues was also investigated via an empirical survey employing more than 7,000 users from 10 countries and was found to be significantly low.

    2008-01-01

    The present invention discloses a lanthanide-halide based humidity indicator and method of producing such indicator. The color of the present invention indicates the humidity of an atmosphere to which it is exposed. For example, impregnating an adsorbent support such as silica gel with an aqueous solution of the europium-containing reagent solution described herein, and dehydrating the support to dryness forms a substance with a yellow color. When this substance is exposed to a humid atmosphere the water vapor from the air is adsorbed into the coating on the pore surface of the silica gel. As the water content of the coating increases, the visual color of the coated silica gel changes from yellow to white. The color change is due to the water combining with the lanthanide-halide complex on the pores of the gel.

    A topological index can be considered as transformation of chemical structure in to real number. In QSAR/QSPR study, physicochemical properties and topological indices such as Randić, Zagreb, atom-bond connectivity ABC, and geometric-arithmetic GA index are used to predict the bioactivity of chemical compounds. Dendrimers are highly branched, star-shaped macromolecules with nanometer-scale dimensions. Dendrimers are defined by three components: a central core, an interior dendritic structure (the branches), and an exterior surface with functional surface groups. In this paper we determine generalised Randić, general Zagreb, general sum-connectivity indices of poly(propyl) ether imine, porphyrin, and zinc-Porphyrin dendrimers. We also compute ABC and GA indices of these families of dendrimers.

    2015-01-01

    Modeling wind speed is one of the key element when dealing with the production of energy through wind turbines. A good model can be used for forecasting, site evaluation, turbines design and many other purposes. In this work we are interested in the analysis of the future financial cash flows generated by selling the electrical energy produced. We apply an indexed semi-Markov model of wind speed that has been shown, in previous investigation, to reproduce accurately the statistical behavior of wind speed. The model is applied to the evaluation of financial indicators like the Internal Rate of Return, semi-Elasticity and relative Convexity that are widely used for the assessment of the profitability of an investment and for the measurement and analysis of interest rate risk. We compare the computation of these indicators for real and synthetic data. Moreover, we propose a new indicator that can be used to compare the degree of utilization of different power plants.

    In 2002, world leaders committed, through the Convention on Biological Diversity, to achieve a significant reduction in the rate of biodiversity loss by 2010. We compiled 31 indicators to report on progress toward this target. Most indicators of the state of biodiversity (covering species' population trends, extinction risk, habitat extent and condition, and community composition) showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity (including resource consumption, invasive alien species, nitrogen pollution, overexploitation, and climate change impacts) showed increases. Despite some local successes and increasing responses (including extent and biodiversity coverage of protected areas, sustainable forest management, policy responses to invasive alien species, and biodiversity-related aid), the rate of biodiversity loss does not appear to be slowing.

    Full Text Available Sustainable development requires better quality of life for present and future generations. Additional data is required to measure lasting progress, that tracks economic growth. The objectives that take these aspects into consideration should be accompanied by economic, social, environmental and demographic indicators. Thus, sustainable development indicators satisfy these requirements. The articles makes an analysis of the main indicators of sustainable development. Even though it is important to observe them at a macro, European level, it is necessary to take into consideration the specific situation existing at a local and regional level, as well. Equally important is the integration of objectives aimed at sustainable development into the national policies. Economic improvement can be achieved through jobs and sustainable consumption.

    The spectral signature of nanoplasmonic films are both robust and tailorable with optical responses ranging from the visible to the near-infrared. We present the development of flexible, elastomeric nanoplasmonic films consisting of periodic arrays of gold nanocups as tamper indicating films. Gold nanocups have polarization-sensitive optical properties that may be manufactured into films that offer unique advantages for tamper indication. These flexible films can be made quickly and at low-cost using commercially available monodisperse polystyrene nanospheres through self-assembly followed by plasma etching, metal deposition, and lift-off from a sacrificial substrate. Polarization- and angle-dependent optical spectroscopic measurements were performed to characterize the fabricated films. Using polarization-sensitive hyperspectral imaging, we demonstrate how these films can be applied to tamper indication and counterfeit resistance applications.

    Full Text Available Research on the hypothalamic pituitary adrenal (HPA axis has involved a proliferation of cortisol indices. We surveyed recently published HPA-related articles and identified 15 such indices. We sought to clarify their biometric properties, specifically, how they interrelate and what they mean, because such information is rarely offered in the articles themselves. In the present article, the primary samples consist of community mothers and their infants (N = 297, who participated in two challenges, the Toy Frustration Paradigm and the Strange Situation Procedure. We sought to cross-validate findings from each of these samples against the other, and also against a clinically depressed sample (N = 48 and a sample of healthy older adults (N = 51 who participated in the Trier Social Stress Test. Cortisol was collected from all participants once before and twice after the challenges. These heterogenous samples were chosen to obtain the greatest possible range in cortisol levels and stress response regulation. Using these data, we computed the 15 summary cortisol indices identified in our literature survey. We assessed inter-relations amongst indices and determined their underlying dimensions via principal component analysis (PCA. The PCAs consistently extracted two components, accounting for 79%–93% of the variance. These components represent “total cortisol production” and “change in cortisol levels.” The components were highly congruent across challenge, time, and sample. High variable loadings and explained factor variance suggest that all indices represent their underlying dimensions very well. Thus the abundance of summary cortisol indices currently represented in the literature appears superfluous.

  12. Performance indicators to evaluate Spatial Data Infrastructures

    Full Text Available The importance of geographic information in decision-making and the ability of Spatial Data Infrastructures to transform government actions from a spatial perspective have placed the IDE as a fundamental solution in decision-making at many levels. In view of its relevance and major investments in this area, there is great interest in different sectors of society to observe the impact of the IDE, its evolution and future scenarios. This creates the need for an assessment of its impact, to obtain an approximate measure the success of these initiatives. This requires the availability of reliable mechanisms of evaluation from different approaches and objectives, which does not prevent, despite having a wide variety of studies and proposals, remains a difficult task. As part of the evaluation and monitoring IDE there is a variety of approaches using performance indicators as valid to estimate their development mechanism. In this context it is noted, the effort of experts and organizations, by agreeing a method to evaluate the IDE on the one hand and to define indicators, which are the essential part of various methodological approaches on the other. Given that the indicators are principally a desire to measure, marked differences in purpose of evaluation, the name and scope of the indicators themselves are observed, which indicates there is still much work to be done. This article presents a comparative analysis of the use of indicators for monitoring and evaluation of IDE development, which has been considered the study of five major initiatives: IDEC of Catalonia, GIDEON the Netherlands, eSDI-Net + e INSPIRE European and UN-GGIM of America.

  13. Pediatric tracheotomy: are the indications changing?

    Lawrason, Amy; Kavanagh, Katherine

    2013-06-01

    The most common indications for tracheotomy in pediatric patients include upper airway obstruction, prolonged ventilator dependence, and hypotonia secondary to neurologic impairment. In this study we review the indications for tracheotomy within our patient population over the last 11 years. We conducted a retrospective chart review of consecutive patients undergoing tracheotomy at a tertiary care pediatric hospital from January 2000 to April 2011. We evaluated patient age, sex, pre-operative and post-operative diagnosis, and direct laryngoscopic and bronchoscopic findings. Patients were divided into six groups based on their indication for tracheotomy. In order to assess changing indications for tracheotomy over time, we compared an early (2000-2005) and a late (2006-2011) patient group. We had complete data available on 158/165 patients (95.8%) who underwent tracheotomy from 2000 to 2011. There was no significant difference in mean age between the early and late groups (4.73 ± 6.0 years vs. 3.6 ± 5.5 years, p=0.26). There was a change in the most common indication for tracheotomy between the early and late groups, with upper airway obstruction becoming more common in the late group and significantly fewer patients undergoing tracheotomy for prolonged ventilation in the late group (33/76 (43%) vs. 23/82 (28%), p=0.05). More patients underwent bronchoscopy at the time of tracheotomy in the late group (52/82 (63%) vs. 28/76 (37%), p=tracheotomy experience demonstrated a change in the most common indication for tracheotomy between 2000 and 2011. In our patient population, there was a significant decline in the number of tracheotomies performed for prolonged intubation and an increasing number of patients who required tracheotomy for upper airway obstruction.

    Laparoscopic adrenalectomy has become a standard surgical procedure for the most of adrenal gland disorders. Hormonal active adenomas, feochromocytomas even some malignant tumors are the most frequent indications. The number of operations for accidentally diagnosed foci has grown rapidly. It has been suggested to revise recommendations specifying criteria, based on which incidentaloma is indicated for adrenalectomy. The aim of this work is to compare the results of adrenalectomies for hormonal active lesions and incidentalomas. An analysis of 65 patients who underwent adrenalectomy in the Department of Surgery University Hospital Brno Bohunice from 2005 to 2010. Correlation between preoperative examination outcomes and postoperative histology findings was performed. Furthermore, findings in patients indicated for surgery for hormonally active versus for hormonally inactive suprarenal tumors were compared. Thirty-eight patients underwent laparoscopic surgery for hormonally active adrenal tumors, one for bilateral metastasses of bronchogenic carcinoma. In 26 cases adrenalectomy was indicated for incidentaloma. Adrenal hyperplasia was the commonest histological finding in the group with hormonally inactive tumors. No carcinoma was detected in this group. In 5 of 19 patients operated for suspective feochromocytoma, the procedure did not result in blood pressure adjustment and feochromocytoma was histologically confirmed in 11 out of the 19 subjects. The size of the tumors was significantly higher in incidentalomas, compared to hormonally active pathologies. No incidentaloma and hypertension subjects experienced alteration in their clinical condition after the procedure. Laparoscopic adrenalectomy is a standard procedure in the majority of hormonally active focal suprarenal conditions. Patients with accidentally detected suprarenal tumors should be carefully indicated, taking into consideration internal comorbidities and any surgical procedures in a patient's history

    Knasel, A L; Collins-Barrow, M D

    1986-11-01

    Leukocytosis, blood glucose, vomiting, diarrhea, and abdominal radiograph have been reported as early indicators of toxic serum iron levels. To test the applicability of this battery of five variables, the charts of 64 patients admitted for toxic iron ingestion were reviewed. When these variables were subjected to tests of sensitivity, specificity, and predictive negative and positive values in 42 patients meeting study criteria, they failed to reach statistical significance. Only vomiting was found to approach statistical significance and, therefore, may serve as an early indicator of toxicity. In addition, several epidemiological issues relevant to the study population are discussed.

    Diabetes mellitus is one of the major causes of morbidity and mortality in EU/EFTA countries. Monitoring risk factors for diabetes and its complications will offer the possibility to evaluate the development in time as well as the influence of possible interventions. In this investigation a list with core and secondary indicators is proposed. Availability of these indicators and their data sources is discussed. An important variability of data sources is used in EU/EFTA countries, interfering with the comparability of the outcome. Further harmonisation as well as continuous evaluation of data sources will be necessary to provide reliable tools to monitor diabetes mellitus and its outcome on a routine basis.

    (1) The licensed indications of topiramate have been extended to cover treatment (in combination with an inadequately effective ongoing treatment) of generalised tonic-clonic epilepsy in adults and children over four years, and partial epilepsy in children over four. (2) The efficacy of topiramate was established in two double-blind, placebo-controlled trials in patients with generalised tonic-clonic epilepsy, and in a double-blind, placebo-controlled trial in patients with partial epilepsy. (3) Topiramate has not been compared with other antiepileptics with similar indications, i.e. lamotrigine and vigabatrin. (4) Topiramate appears to be relatively well tolerated.

    2010-03-16

    We describe herein a novel approach for visual indication of trace organic vapors. The sensor utilizes a microporous material within a visual thin film transducer to produce changes in color upon exposure to a very wide range of volatile organic compounds. Visual indication at 5 parts per million (ppm) is demonstrated, with optoelectronic detection achieved to below 50 parts per billion (ppb). Through a thoughtful design of the sensor, we are able to avoid interference from water vapor, a critical attribute needed for practical application.

    Full Text Available Food packaging is an important part of food production. Temperature is a one of crucial factor which affecting the quality and safety of food products during distribution, transport and storage. The one way of control of food quality and safety is the application of new packaging systems, which also include the intelligent or smart packaging. Intelligent packaging is a packaging system using different indicators for monitoring the conditions of production, but in particular the conditions during transport and storage. Among these indicators include the time-temperature indicators to monitor changes in temperature, which is exposed the product and to inform consumers about the potential risks associated with consumption of these products. Time temperature indicators are devices that show an irreversible change in a physical characteristic, usually color or shape, in response to temperature history.

    Safety indicators play a role in providing information on organizational performance, motivating people to work on safety and increasing organizational potential for safety. The aim of this report is to provide an overview on leading safety indicators in the domain of nuclear safety. The report explains the distinction between lead and lag indicators and proposes a framework of three types of safety performance indicators - feedback, monitor and drive indicators. Finally the report provides guidance for nuclear energy organizations for selecting and interpreting safety indicators. It proposes the use of safety culture as a leading safety performance indicator and offers an example list of potential indicators in all three categories. The report concludes that monitor and drive indicators are so called lead indicators. Drive indicators are chosen priority areas of organizational safety activity. They are based on the underlying safety model and potential safety activities and safety policy derived from it. Drive indicators influence control measures that manage the socio technical system; change, maintain, reinforce, or reduce something. Monitor indicators provide a view on the dynamics of the system in question; the activities taking place, abilities, skills and motivation of the personnel, routines and practices - the organizational potential for safety. They also monitor the efficacy of the control measures that are used to manage the socio technical system. Typically the safety performance indicators that are used are lagging (feedback) indicators that measure the outcomes of the socio technical system. Besides feedback indicators, organizations should also acknowledge the important role of monitor and drive indicators in managing safety. The selection and use of safety performance indicators is always based on an understanding (a model) of the socio technical system and safety. The safety model defines what risks are perceived. It is important that the safety

    Motivated by the high cost of human curation of biological databases, there is an increasing interest in using computational approaches to assist human curators and accelerate the manual curation process. Towards the goal of cataloging drug indications from FDA drug labels, we recently developed LabeledIn, a human-curated drug indication resource for 250 clinical drugs. Its development required over 40 h of human effort across 20 weeks, despite using well-defined annotation guidelines. In this study, we aim to investigate the feasibility of scaling drug indication annotation through a crowdsourcing technique where an unknown network of workers can be recruited through the technical environment of Amazon Mechanical Turk (MTurk). To translate the expert-curation task of cataloging indications into human intelligence tasks (HITs) suitable for the average workers on MTurk, we first simplify the complex task such that each HIT only involves a worker making a binary judgment of whether a highlighted disease, in context of a given drug label, is an indication. In addition, this study is novel in the crowdsourcing interface design where the annotation guidelines are encoded into user options. For evaluation, we assess the ability of our proposed method to achieve high-quality annotations in a time-efficient and cost-effective manner. We posted over 3000 HITs drawn from 706 drug labels on MTurk. Within 8 h of posting, we collected 18 775 judgments from 74 workers, and achieved an aggregated accuracy of 96% on 450 control HITs (where gold-standard answers are known), at a cost of $1.75 per drug label. On the basis of these results, we conclude that our crowdsourcing approach not only results in significant cost and time saving, but also leads to accuracy comparable to that of domain experts.

  11. Soil Quality Indicator: a new concept

    Science.gov (United States)

    Barão, Lúcia; Basch, Gottlieb

    2017-04-01

    During the last century, cultivated soils have been intensively exploited for food and feed production. This exploitation has compromised the soils' natural functions and many of the soil-mediated ecosystems services, including its production potential for agriculture. Also, soils became increasingly vulnerable and less resilient to a wide range of threats. To overcome this situation, new and better management practices are needed to prevent soil from degradation. However, to adopt the best management practices in a specific location, it is necessary to evaluate the soil quality status first. Different soil quality indicators have been suggested over the last decades in order to evaluate the soil status, and those are often based on the performance of soil chemical, physical and biological properties. However, the direct link between these properties and the associated soil functions or soil vulnerability to threats appears more difficult to be established. This present work is part of the iSQAPER project- Interactive Soil Quality Assessment in Europe and China for Agricultural Productivity and Environmental Resilience, where new soil quality concepts are explored to provide better information regarding the effects of the most promising agricultural management practices on soil quality. We have developed a new conceptual soil quality indicator which determines the soil quality status, regarding its vulnerability towards different threats. First, different indicators were specifically developed for each of the eight threats considered - Erosion, SOM decline, Poor Structure, Poor water holding capacity, Compaction, N-Leaching, Soil-borne pests and diseases and Salinization. As an example for the case of Erosion, the RUSLE equation for the estimate of the soil annual loss was used. Secondly, a reference classification was established for each indicator to integrate all possible results into a Good, Intermediate or Bad classification. Finally, all indicators were

  12. FINANCIAL INDICATORS IN MANAGERIAL DECISION-MAKING

    Directory of Open Access Journals (Sweden)

    Fenyves Veronika

    Full Text Available Working capital is crucial to determine the short-term financial position of a given company. Significant changes in working capital provide important information to the stakeholders. Working capital analysis is one of the methods of credit rating and it can also help to better understand the business cycle of a given company. One of the key elements of working capital management is liquidity management, that is, to maintain a company’s ability to pay continuously, because in the short-term, it ensures the company to stay afloat, and justifies its progress on the long-term. Decision makers are in need of such indicators and interrelations that can help precisely assessing the real situation and recognise problems of funding in time. Achieving this goal is a very complex task because the use of several indicators and perspectives are necessary to measure liquidity. For this, companies have to develop management and organizational structures that provide an adequate framework to measure and follow up liquidity. To facilitate this, the study draws attention to interrelations that anticipate the actual liquidity position of a company more precisely. Generally, liquidity indicators are being used to measure a company’s ability to pay, but those do not sufficiently take into account for how long different components are tied up during the operation. Adjusted liquidity indicators can be calculated to solve these problems as these include the time an asset is in the operating cycle in the case of current assets and short-term liabilities. At the same time, these days the continuous monitoring and analysis of operational data has become essential, too. The database which has been created as a result of the annual financial statement reporting obligation that was introduced by the Act C in 2000 can be used to analyse company data on a yearly basis. However, in case we would like to examine the changes of these indicators continuously during the

    Many changes have been made in different sciences by developing and advancing information and communication technology in last two decades. E-health is a very broad term that includes many different activities related to the use of electronic devices, software as well as hardware in health organizations. The aim of this study is comparing electronic health indicators in the selected countries and discussion on the best indicators. This study has chosen 12 countries randomly based on the regional division of the WHO. The relevant numbers of health indicators and general indicators and information technology indicators are extracted of these countries. We use data from the Bitarf's comparative study, which is conducted by the Iranian Supreme Council of Information Technology in 2007. By using Pearson correlation test, the relations between health general indicators and IT indicators are studied. Data was analyzed based on the research objectives using SPSS software and in accordance with research questions Pearson correlation test were used. The findings show that there is a positive relation between indicators related to IT and "Total per capita health, healthy life expectancy, percent literacy". Furthermore, there is a mutual relation between IT indicators and "mortality indicator". This study showed differences between selective indicators among different countries. The modern world, with its technological advances, is not powerless in the face of these geographic and health disparity challenges. Researchers must not rely on the available indicators. They must consider indicators like e-business companies, electronic data internet, medical supplies, health electronic record, health information system, etc., In future, continuous studies in this field, to provide the exact and regular reports of amount of using of these indicators through different countries must be necessary.

    2015-07-01

    We study the topological properties of the information transfer networks (ITN) of the global financial market indices for six different periods. ITN is a directed weighted network, in which the direction and weight are determined by the transfer entropy between market indices. By applying the threshold method, it is found that ITN undergoes a crossover from the complete graph to a small-world (SW) network. SW regime of ITN for a global crisis is found to be much more enhanced than that for ordinary periods. Furthermore, when ITN is in SW regime, the average clustering coefficient is found to be synchronized with average volatility of markets. We also compare the results with the topological properties of correlation networks.

  15. [Extend the indications of medical abortion].

    Zaidman, H

    1971-01-01

    This is a personal viewpoint resulting in part from the author's doctoral thesis on widening the indications for therapeutic abortion France. After praising the stand for medical abortion taken by Prof. Fruhinsholz, his advisor, and giving a brief history of the concept of therapeutic abortion, the authro concludes that most writers agree on the principle of such abortion, but disagree on indications. The French law of 1939 permits abortion only to save the mother's life if it is ser iously and immediately endangered. No mention is made of necessary functions such as sight, of disorders that can only be treated by procedures injurious to fetal development, of health endangered by pregnancy, or of subsequent social or economic impairment. The author believes that abortion is a social, not moral problem, but concluded by saying that to abandon a child to public assistance is more immoral than abortion.

  16. Delamination-Indicating Thermal Barrier Coatings

    Science.gov (United States)

    Eldridge, Jeffrey I.

    2007-01-01

    The risk of premature failure of thermal barrier coatings (TBCs), typically composed of yttria-stabilized zirconia (YSZ), compromises the reliability of TBCs used to provide thermal protection for turbine engine components. Unfortunately, TBC delamination proceeds well beneath the TBC surface and cannot be monitored by visible inspection. Nondestructive diagnostic tools that could reliably probe the subsurface damage state of TBCs would alleviate the risk of TBC premature failure by indicating when the TBC needs to be replaced before the level of TBC damage threatens engine performance or safety. To meet this need, a new coating design for thermal barrier coatings (TBCs) that are self-indicating for delamination has been successfully implemented by incorporating a europium-doped luminescent sublayer at the base of a TBC composed of YSZ. The luminescent sublayer has the same YSZ composition as the rest of the TBC except for the addition of low-level europium doping and therefore does not alter TBC performance.

    This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration modelling framework. The analysis is undertaken using monthly data from January 2000 to August 2011. The results suggest nonstationary long memory in the series (with orders of integration equal to or higher than 1) when breaks are not allowed for. However, endogenous break tests indicate a single break in all series except for producer prices for lignite for which two breaks are detected. When such breaks are taken into account, and with autocorrelated disturbances, evidence of mean reversion is found in practically all cases.

    Russia is sometimes referred to as 'the Saudi Arabia of energy efficiency'; its vast potential to reduce energy consumption can be considered a significant 'energy reserve'. Russia, recognising the benefits of more efficient use of energy, is taking measures to exploit this potential. The president has set the goal to reduce energy intensity by 40% between 2007 and 2020. In the past few years, the IEA has worked closely with Russian authorities to support the development of energy efficiency indicators in Russia, critical to an effective implementation and monitoring of Russia's ambitious energy intensity and efficiency goals. The key findings of the IEA work with Russia on developing energy efficiency indicators form the core of this report.

    2012-01-01

    Full Text Available Aberrations in the complement system have been shown to be direct or indirect pathophysiological mechanisms in a number of diseases and pathological conditions such as autoimmune disease, infections, cancer, allogeneic and xenogeneic transplantation, and inflammation. Complement analyses have been performed on these conditions in both prospective and retrospective studies and significant differences have been found between groups of patients, but in many diseases, it has not been possible to make predictions for individual patients because of the lack of sensitivity and specificity of many of the assays used. The basic indications for serological diagnostic complement analysis today may be divided into three major categories: (a acquired and inherited complement deficiencies; (b disorders with complement activation; (c inherited and acquired C1INH deficiencies. Here, we summarize indications, techniques, and interpretations for basic complement analyses and present an algorithm, which we follow in our routine laboratory.

  1. Ciclosporin 10 years on: indications and efficacy

    Forsythe, Peter; Paterson, Sue

    2014-01-01

    Ciclosporin is a lipophilic cyclic polypeptide with powerful immunosuppressive and immunomodulatory properties that has been used in veterinary medicine for two decades. It is a calcineurin inhibitor whose principal mode of action is to inhibit T cell activation. The drug is principally absorbed from the small intestine and is metabolised in the intestine and liver by the cytochrome P450 enzyme system. Ciclosporin is known to interact with a wide range of pharmacological agents. Numerous studies have demonstrated good efficacy for the management of canine atopic dermatitis and this has been a licensed indication since 2003. In addition to the treatment of atopic dermatitis, it has been used as an aid in the management of numerous other dermatological conditions in animals including perianal fistulation, sebaceous adenitis, pododermatitis, chronic otitis externa and pemphigus foliaceus. This article reviews the mode of action, pharmacokinetics, indications for use and efficacy of ciclosporin in veterinary dermatology. PMID:24682697

    2007-11-01

    We explore the deviations from efficiency in the returns and volatility returns of Latin-American market indices. Two different approaches are considered. The dynamics of the Hurst exponent is obtained via a wavelet rolling sample approach, quantifying the degree of long memory exhibited by the stock market indices under analysis. On the other hand, the Tsallis q entropic index is measured in order to take into account the deviations from the Gaussian hypothesis. Different dynamic rankings of inefficieny are obtained, each of them contemplates a different source of inefficiency. Comparing with the results obtained for a developed country (US), we confirm a similar degree of long-range dependence for our emerging markets. Moreover, we show that the inefficiency in the Latin-American countries comes principally from the non-Gaussian form of the probability distributions.

    We present a study in which we searched for a correlation between weak Na absorption doublet (8183Å, 8194Å) and strong H-Alpha emission (6563Å) in late-M dwarf stars (M6-M9), as both are indicative of youth. Our sample consists of late-M Dwarfs from the LSPM Survey (Lépine and Shara, 2005), which contain stars with measured proper motions of mu > 40 mas/yr.

  4. Alternative indicators for measuring hospital productivity.

    Science.gov (United States)

    Serway, G D; Strum, D W; Haug, W F

    1987-08-01

    This article explores the premise that the appropriateness and usefulness of typical hospital productivity measures have been affected by three changes in delivery: Organizational restructuring and other definition and data source changes that make full-time equivalent employee (FTE) measurements ambiguous. Transition to prospective payment (diagnosis-related groups). Increase in capitation (prepaid, at risk) programs. The effects of these changes on productivity management indicate the need for alternative productivity indicators. Several productivity measures that complement these changes in internal operations and the external hospital business environment are presented. These are based on an analysis of four hospitals within a multihospital system, and an illustration and interpretation of an array of measures, based on ten months of actual data, is provided. In conclusion, the recommendation is made for hospital management to collect an expanded set of productivity measures and review them in light of changing expense and revenue management schemes inherent in new payment modes.

    credibility are disputed. Our present goal is to improve the value of stranding data as population indicator as part of monitoring strategies by constructing the spatial and temporal null hypothesis for strandings. The null hypothesis is defined as: small cetacean distribution and mortality are uniform...... conditions did not explain observed seasonal variations of porpoise strandings. Long-term stranding anomalies increased first in the southern North Sea, the Channel and Bay of Biscay coasts, and finally the eastern North Sea. The hypothesis of changes in porpoise distribution was consistent with local visual...... surveys, mostly SCANS surveys (1994 and 2005). This new indicator could be applied to cetacean populations across the world and more widely to marine megafauna....

    2016-07-01

    Healthcare and life sciences are among the most important drivers which form the present-day landscape of science and technology in general. A whole range of emerging areas of research and disruptive technologies are related to healthcare. The applied nature of such areas of research makes it important to specify indicators which describe these areas not only from R&D, but also from user need side. We analyze the content of domain-specific social media and online consulting services in healthcare with the help of semantic technologies in order to extract widespread and emerging user needs. We will map the corresponding topics on the agenda of scientific papers in healthcare. Understanding the intersection of these two agendas and the coverage of user needs by science and technology activities leads us to the development of the “market pull” indicators for emerging areas of research.

    To quantify the force of selection, Hamilton [Hamilton, W. D. (1966) J. Theor. Biol. 12, 12-45] derived expressions for the change in fitness with respect to age-specific mutations. Hamilton's indicators are decreasing functions of age. He concluded that senescence is inevitable: survival...... and fertility decline with age. I show that alternative parameterizations of mutational effects lead to indicators that can increase with age. I then consider the case of deleterious mutations with age-specific effects. In this case, it is the balance between mutation and selection pressure that determines...... the equilibrium number of mutations in a population. In this balance, the effects of different parameterizations cancel out, but only to a linear approximation. I show that mutation accumulation has little impact at ages when this linear approximation holds. When mutation accumulation matters, nonlinear effects...

    Rajanikmanth, P V; Kate, V; Ananthakrishnan, N

    2001-01-01

    There is lack of data on risk factors, which, if present, would indicate the need for surgery in patients with adhesive bowel obstruction. A Cohort of 100 consecutive patients with adhesive obstruction was studied prospectively to compare clinical and investigative parameters between the operative and conservative group. It was found that female gender, previous obstetric or gynaecological procedures, pulse and BP on admission, nature of nasogastric aspirate, single distended loop on abdominal x-ray as also predominant ileal distension were independent factors indicating a high probability of surgical intervention. Patients with 2 or more risk factors had 12 times higher probability of surgery and in those with 3 or more the relative risk was 30 times. Patients with such risk factors should be monitored closely after admission and should be taken for surgery after an initial short trial of conservative measures.

    2012-01-01

    Magnesium is essential for a wide variety of biochemical reactions and physiological functions, but its regulatory mechanisms (both at the cellular and at the systemic level) are still poorly characterized. Not least among the reasons for this gap are the technical difficulties in sensing minor changes occurring over a high background concentration. Specific fluorescent indicators are highly sensitive tools for dynamic evaluation of intracellular magnesium concentration. We herein discuss the main criteria to consider when choosing a magnesium-specific fluorescent indicator and provide examples among commercial as well as developmental sensors. We focus on spectrofluorimetric approaches to quantify Mg(2+) concentration in cell or mitochondria suspensions, and on imaging techniques to detect intracellular magnesium distribution and fluxes by live microscopy, reporting a detailed description of standard protocols for each method. The general guidelines we provide should be applicable to specific issues by any researcher in the field. Copyright © 2012 Elsevier Inc. All rights reserved.

    In this paper, we investigate the dynamics in electron billiards by using classical and quantum mechanical calculations. We report on the existence of pointer states in single-dot and double-dot electron billiards. Additionally, we show that the two types of pointer states have the propensity to create offspring, i.e. they can be observed in the individual modes propagating between the external reservoirs. This can be understood as an indication that quantum Darwinism is present in the electron billiards.

    Indicators are usually thought of as measurements or calculations that represent important features of the status, trend, or performance of a system of interest (e.g. the economy, agriculture, air quality). They are often used for the most practical of reasons – one cannot measure everything important about systems of interest, so there is a practical need to identify major features that can be reported periodically and used to guide both research and decisions (NRC 2000).

    In this paper, we apply multidimensional scaling (MDS) and parametric similarity indices (PSI) in the analysis of complex systems (CS). Each CS is viewed as a dynamical system, exhibiting an output time-series to be interpreted as a manifestation of its behavior. We start by adopting a sliding window to sample the original data into several consecutive time periods. Second, we define a given PSI for tracking pieces of data. We then compare the windows for different values of the parameter, an...

    The objective of this study was to determine if there are differences in decannulation rates and duration of cannulation between pediatric patients undergoing tracheotomy for different indications. Retrospective chart review. Medical records for pediatric patients (age 0-18 years) undergoing tracheotomy between January 1, 2003, and May 31, 2012, were retrospectively reviewed. Patients were assigned an indication for tracheotomy from five categories: neurological, cardiopulmonary, upper airway obstruction, craniofacial anomalies, and maxillofacial/laryngotracheal trauma. Initial chart review identified 124 patients, 113 for whom complete data was available. Of these patients, the indications for tracheotomy were cardiopulmonary disease in 24 (21.2%), craniofacial anomalies in 12 (10.6%), neurological impairment in 44 (38.9%), traumatic injury in 11 (9.7%), and upper airway obstruction in 22 (19.5%). The time to decannulation was shorter for trauma patients compared to cardiopulmonary (P = 0.044) and neurological patients (P = 0.001). A total of 32 (31.9%) patients were decannulated during the study period, with a higher rate in trauma patients (72.7%) and a lower rate in those with upper airway obstruction (36.4%) than would be expected under homogeneity. Of the 32 patients who were decannulated, 11 (30.6%) were decannulated during the same hospitalization in which the tracheotomy was performed. This study demonstrates a difference in overall decannulation rates and a shorter time to decannulation in children undergoing tracheotomy for maxillofacial and laryngotracheal trauma compared to cardiopulmonary and neurological indications. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    There is no good reason why a gallbladder that has been compressed and displaced by a parasitic or malformative cyst, but is otherwise free of anatomical or irreversible lesions, should be irrevocably sacrificed. Treatment of the primary lesion can thus be followed by re-implantation of the gallbladder. The indications for this surgical technique and its limitations are described with reference to a personal series.

    Behaviour represents a reaction to the environment as fish perceive it and is therefore a key element of fish welfare. This review summarises the main findings on how behavioural changes have been used to assess welfare in farmed fish, using both functional and feeling-based approaches. Changes in foraging behaviour, ventilatory activity, aggression, individual and group swimming behaviour, stereotypic and abnormal behaviour have been linked with acute and chronic stressors in aquaculture and can therefore be regarded as likely indicators of poor welfare. On the contrary, measurements of exploratory behaviour, feed anticipatory activity and reward-related operant behaviour are beginning to be considered as indicators of positive emotions and welfare in fish. Despite the lack of scientific agreement about the existence of sentience in fish, the possibility that they are capable of both positive and negative emotions may contribute to the development of new strategies (e.g. environmental enrichment) to promote good welfare. Numerous studies that use behavioural indicators of welfare show that behavioural changes can be interpreted as either good or poor welfare depending on the fish species. It is therefore essential to understand the species-specific biology before drawing any conclusions in relation to welfare. In addition, different individuals within the same species may exhibit divergent coping strategies towards stressors, and what is tolerated by some individuals may be detrimental to others. Therefore, the assessment of welfare in a few individuals may not represent the average welfare of a group and vice versa. This underlines the need to develop on-farm, operational behavioural welfare indicators that can be easily used to assess not only the individual welfare but also the welfare of the whole group (e.g. spatial distribution). With the ongoing development of video technology and image processing, the on-farm surveillance of behaviour may in the near

    Endoscopic sinus surgery is the technique of choice in most of the frontal sinus diseases, both inflammatory and tumour-related. This is why the external approach using osteoplastic flap (OF) would be limited to cases with a difficult endoscopic approach. Our aim was to review the current indications of the osteoplastic flap in the treatment of frontal sinus pathology, through a retrospective study of patients undergoing this technique. We performed a retrospective study of 14 patients who were treated with the osteoplastic flap procedure. All the surgical indication criteria, type of sinus disease, presence or absence of prior endoscopic surgery, surgical findings, complications and recurrence were reviewed. The pathologies found were 1 osteoma (7.1%), 3 inverted papilloma (21.4%) and 10 mucoceles (71.4%). Nine patients had a prior endoscopic surgery and 10 patients had an orbital dehiscence (9 mucocele, 1 papilloma). Frontal osteoma was Grade IV and the papilloma cases were Krouse Stage III. Surgical revision was required for 21.4%. The main indications for an OF in patients with inflammatory disease are lateral extension and frontal recess neo-osteogenesis. In osteoma cases, it depends on the size of the tumour. In inverted papilloma cases, the indication is multifocal implantation with origin in the anterior and lateral wall. In all cases, performing the osteoplastic flap must be individualised. Copyright © 2014 Elsevier España, S.L.U. and Sociedad Española de Otorrinolaringología y Patología Cérvico-Facial.

Twenty-eight services, represented by a collection of indicators and metrics, have been identified as influencing these domains of human well-being. By taking an inventory of stocks or measuring the results of a service, a relationship function can be derived to understand how changes in the provisioning of that service can influence the HWBI. An extensive review of existing services was performed to identify current services, indicators and metrics in use. This report describes the indicators and methods we have selected to evaluate the provisioning of economic, ecosystem, and social services related to human well-being.

    How far in advance can the sunspot number be predicted with any degree of confidence? Solar cycle predictions are needed to plan long-term space missions. Fleets of satellites circle the Earth collecting science data, protecting astronauts, and relaying information. All of these satellites are sensitive at some level to solar cycle effects. Statistical and timeseries analyses of the sunspot number are often used to predict solar activity. These methods have not been completely successful as the solar dynamo changes over time and one cycle's sunspots are not a faithful predictor of the next cycle's activity. In some ways, using these techniques is similar to asking whether the stock market can be predicted. It has been shown that the Dow Jones Industrial Average (DJIA) can be more accurately predicted during periods when it obeys certain statistical properties than at other times. The Hurst exponent is one such way to partition the data. Another measure of the complexity of a timeseries is the fractal dimension. We can use these measures of complexity to compare the sunspot number with other solar and geomagnetic indices. Our concentration is on how trends are removed by the various techniques, either internally or externally. Comparisons of the statistical properties of the various solar indices may guide us in understanding how the dynamo manifests in the various indices and the Sun.

    The Los Alamos National Laboratory (LANL) Intrinsic Tamper Indicating Device (TID) Program has recently been developed in conjunction with the regular LANL TID Program to assist groups who perform measurements using sealed sources or store difficult-to-measure items. The program was then expanded to include other types of sealed sources and items processed for long-term storage in the Nuclear Material Packaging and Repackaging Program. The Intrinsic TID Program encompasses both Special Nuclear Material (SNM) and Nuclear Material (NM) items that have intrinsic characteristics that would immediately indicate tampering upon visual inspection. Items determined to be intrinsically sealed do not need to be sealed with authorized tamper indicating devices. Under the program, an identified intrinsic item receives the same safeguards credits as other tamper-sealed items already in the TID Program. The major benefits of the Intrinsic TID Program include reducing verification measurements on intrinsically identified inventory items and reducing exposure to operators working in highly irradiated environments. Intrinsic TIDs should be combined with other safeguards requirements, and items should have defensible measurements as well as visual inspections. Several groups at LANL are already implementing the program and providing feedback so that we can tailor it to better meet the customers` needs.

  12. Developing a size indicator for fish populations

    Directory of Open Access Journals (Sweden)

    Yong Chen

    2008-06-01

    Full Text Available Monitoring temporal and/or spatial variations in fish size-at-age data can often provide fisheries managers with important information about the status of fish stocks and therefore help them identify necessary changes in management policies. However, due to the multivariate nature of size-at-age data, commonly used single-age-based approaches ignore covariance between sizes of different age groups. Different results may therefore be derived when evaluating temporal variations using different age groups for the comparison. The possibility of atypical errors in size-at-age data due to ageing and measurement errors further complicates the comparison. We propose a two-step approach for developing an indicator for monitoring temporal and/or spatial variation in size-at-age data. A robust approach, minimum volume ellipsoid analysis, is used to identify possible outliers in size-at-age data. Then a weighted principal component analysis is applied to the data with the identified outliers down-weighted. An indicator is defined from the resultant principal components for monitoring temporal/spatial variations in size-at-age data. We illustrate the proposed approach with size-at-age data for cod (Gadus morhua in the northwest Atlantic, NAFO subdivision 3Ps. The overall size-at-age indicator identified shows that the pre-1980 year classes tend to have a much higher size-at-age than the post-1980 year classes.

    Johnston, J.W.

    1976-11-01

    A method for estimating the effects of environmental effusions on ecosystems is described. The characteristics of 25 similarity indices used in studies of ecological communities were investigated. The type of data structure, to which these indices are frequently applied, was described as consisting of vectors of measurements on attributes (species) observed in a set of samples. A general similarity index was characterized as the result of a two-step process defined on a pair of vectors. In the first step an attribute similarity score is obtained for each attribute by comparing the attribute values observed in the pair of vectors. The result is a vector of attribute similarity scores. These are combined in the second step to arrive at the similarity index. The operation in the first step was characterized as a function, g, defined on pairs of attribute values. The second operation was characterized as a function, F, defined on the vector of attribute similarity scores from the first step. Usually, F was a simple sum or weighted sum of the attribute similarity scores. It is concluded that similarity indices should not be used as the test statistic to discriminate between two ecological communities.

    Full Text Available The issue of rejection is motivating countless researchers due to the close relationship between peer rejection and difficulties in future adjustment. The study of this issue can contribute towards the detection of factors that trigger rejection, consequently making possible preventive interventions. This text is intended to provide a summary of the research undertaken by the author as part of her Master's Degree, the aim of which was to detect indicators of rejection in the final year of a private primary school in Curitiba (n=52. In this study, “indicators of rejection” are understood to be criteria that lead children to exclude each other from their recreation and working activities, within the context of the school. The study used one instrument designed to collect data from the children (“voting for the least popular” and “tag” and another aimed at obtaining data from the teachers (“teacher's card”. The analysis and cross-referencing of the data obtained indicated that children tend to reject their peers based on their inadequate behaviour (bossiness, disruptive behaviour, and this perception was reinforced by the data obtained from the teachers. On the other hand, children tend to chose other children who frequently demonstrate sociable behaviour to be their peers.

    The concentration of airborne fibers longer than 5 microns, thinner than 3 microns, and with an aspect ratio exceeding 3 as counted by phase contrast optical microscopy is the most widely used fiber exposure index. Recently, more adequate, specific exposure indices for asbestosis, lung cancer, and mesothelioma risk have been suggested by Lippmann. The consequences of using these indices are examined on the basis of calculations for a broad range of theoretical and published size distributions. Optical microscopy appears to be a good predictor of the exposure indices for asbestosis and for lung cancer after scaling. Only fibers longer than about 3 microns need to be counted in a transmission electron microscope. The lung cancer index still cannot explain the large differences of risk among chrysotile exposures. Both the mesothelioma exposure index and the ratio mesothelioma to lung cancer index ranks in order of increasing risk: wollastonite, glass and mineral wool, amosite, glass microfibers, chrysotile, and crocidolite. Amosite is thus not ranked according to epidemiological evidence. Detailed size information should be made available so that the size criteria can be adjusted. It may still prove necessary to use fiber type specific concentration limits.

    The concentration of airborne fibers longer than 5 microns, thinner than 3 microns, and with an aspect ratio exceeding 3 as counted by phase contrast optical microscopy is the most widely used fiber exposure index. Recently, more adequate, specific exposure indices for asbestosis, lung cancer, and mesothelioma risk have been suggested by Lippmann (1988, Environ. Res., 46, 86-106). The consequences of using these indices are examined on the basis of calculations for a broad range of theoretical and published size distributions. Optical microscopy appears to be a good predictor of the exposure indices for asbestosis and for lung cancer after scaling. Only fibers longer than about 3 microns need to be counted in a transmission electron microscope. The lung cancer index still cannot explain the large differences of risk among chrysotile exposures. Both the mesothelioma exposure index and the ratio mesothelioma to lung cancer index ranks in order of increasing risk: wollastonite, glass and mineral wool, amosite, glass microfibers, chrysotile, and crocidolite. Amosite is thus not ranked according to epidemiological evidence. Detailed size information should be made available so that the size criteria can be adjusted. It may still prove necessary to use fiber type specific concentration limits.

    Full Text Available Objective: The aim of this study was to analyze the reticulocyte maturity indices (low, medium, and high fluorescence ratios in iron deficient 1- to 6-year-old children, and identify the prevalence of iron deficiency anemia in this population. Methods: The present study included 39 subjects, divided into two groups: control subjects (n = 33, and subjects with iron deficiency anemia (n = 6. The results were analyzed by Student's t-test for comparison of means. Differences were considered significant when two-tailed p-value < 0.05. Results: Subjects with iron deficiency anemia presented increases in the proportion of mean (10.3 ± 4.7% vs. 6.0 ± 3.4%; p-value = 0.003, and high fluorescence reticulocytes (2.3 ± 0.87% vs. 0.9 ± 0.9%; p-value = 0.03 compared to the control group. The prevalence of anemia in this population was 15% (n = 6. Conclusion: The indices related to immaturity of reticulocytes are higher in the presence of iron deficiency, thus demonstrating a deficiency in the raw material to form hemoglobin and are, therefore, possible early markers of iron deficiency and anemia. We emphasize the need to standardize these indices for use in clinical practice and lab test results.

    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. PMID:26999180

    We analyzed cross-correlations between price fluctuations of global financial indices (20 daily stock indices over the world) and local indices (daily indices of 200 companies in the Korean stock market) by using random matrix theory (RMT). We compared eigenvalues and components of the largest and the second largest eigenvectors of the cross-correlation matrix before, during, and after the global financial the crisis in the year 2008. We find that the majority of its eigenvalues fall within the RMT bounds [ λ -, λ +], where λ - and λ + are the lower and the upper bounds of the eigenvalues of random correlation matrices. The components of the eigenvectors for the largest positive eigenvalues indicate the identical financial market mode dominating the global and local indices. On the other hand, the components of the eigenvector corresponding to the second largest eigenvalue are positive and negative values alternatively. The components before the crisis change sign during the crisis, and those during the crisis change sign after the crisis. The largest inverse participation ratio (IPR) corresponding to the smallest eigenvector is higher after the crisis than during any other periods in the global and local indices. During the global financial the crisis, the correlations among the global indices and among the local stock indices are perturbed significantly. However, the correlations between indices quickly recover the trends before the crisis.

    Different components of global change can have interacting effects on biodiversity and this may influence our ability to detect the specific consequences of climate change through biodiversity indicators. Here, we analyze whether climate change indicators can be affected by land use dynamics that are not directly determined by climate change. To this aim, we analyzed three community-level indicators of climate change impacts that are based on the optimal thermal environment and average lat...

    In healthcare, performance indicators are increasingly used to measure and control quality and efficiency of care-providing teams. This article demonstrates that when controllability is emphasized during indicator development, the level of task uncertainty influences the type of resulting performance indicators. We report findings from a field study in a medical rehabilitation centre in The Netherlands, where four low task uncertain teams ('hand trauma', 'heart failure', 'amputation', 'chronic pain'), and four high task uncertain teams ('children with developmental coordination disorders (DCD)', 'parkinson's disease', 'young children (0-4 years) with developmental disorders', and 'acquired brain injuries') participated in the development of performance indicators using the Productivity Measurement and Enhancement System (ProMES) method. Results show that teams higher on task uncertainty developed relatively more process indicators compared to outcome indicators, whereas the reverse was true for teams lower on task uncertainty. Additionally, process indicators developed by high task uncertain teams were more of a problem solving nature than process indicators developed by low task uncertain teams, which had a more procedural character. The study expands existing knowledge by providing a framework which explicates the task processes to be executed under different levels of task uncertainty, and in line with that appropriate performance indicators for healthcare teams.

    Full Text Available Orientation: Researchers need to assess the psychometric rigour of resilience measuring scales. Research purpose: The purpose of the study was to assess the psychometric properties of the South African Adult Resilience Indicator (ARI.Motivation for the study: Researchers have not previously published the psychometric properties of the South African Adult Resilience Indicator.Research design, approach and method: The authors used a cross-sectional quantitative research design. A sample of 789 young adults participated in the study. Cross-validation allowed the authors to confirm (using the validation sample the validity of the ARI structure they obtained during initial testing (using the calibration sample. They investigated two measurement models (the original factor structure and a one-dimensional factor structure.Main findings: The original factor structure presented the data and the proposed theory better than did the one-dimensional factor structure. The authors found acceptable goodness of fit for the ARI. More specifically, they found invariance (in terms of equal factor loadings,covariances and error variances in the calibration and validation samples. They also found acceptable reliability estimates for each of the eight sub-scales.Practical/managerial implications: The results can help researchers and practitioners interested in measuring resilience in adults to choose a resilience measure and to select an appropriate measure for their populations and contexts.Contribution/value-add: Previous research has clearly shown that reliable and valid resilience measures are necessary. It is also necessary to assess the psychometric properties of the currently available instruments and to publish the findings. This study has helped by examining the psychometric properties of the South African Adult Resilience Indicator.

    Patients with developmental spinal stenosis (DSS) are susceptible to developing symptomatic stenosis due to pre-existing narrowed spinal canals. DSS has been previously defined by MRI via the axial anteroposterior (AP) bony spinal canal diameter. However, MRI is hardly a cost-efficient tool for screening patients. X-rays are superior due to its availability and cost, but currently, there is no definition of DSS based on plain radiographs. Thus, the aim of this study is to develop radiographic indices for diagnosing DSS. This was a prospective cohort of 148 subjects consisting of patients undergoing surgery for lumbar spinal stenosis (patient group) and asymptomatic subjects recruited openly from the general population (control group). Ethics approval was obtained from the local institutional review board. All subjects underwent MRI for diagnosing DSS and radiographs for measuring parameters used for creating the indices. All measurements were performed by two independent investigators, blinded to patient details. Intra- and interobserver reliability analyses were conducted, and only parameters with near perfect intraclass correlation underwent receiver operating characteristic (ROC) analysis to determine the cutoff values for diagnosing DSS using radiographs. Imaging parameters from a total of 66 subjects from the patient group and 82 asymptomatic subjects in the control group were used for analysis. ROC analysis suggested sagittal vertebral body width to pedicle width ratio (SBW:PW) as having the strongest sensitivity and specificity for diagnosing DSS. Cutoff indices for SBW:PW were level-specific: L1 (2.0), L2 (2.0), L3 (2.2), L4 (2.2), L5 (2.5), and S1 (2.8). This is the first study to define DSS on plain radiographs based on comparisons between a clinically relevant patient group and a control group. Individuals with DSS can be identified by a simple radiograph using a screening tool allowing for better cost-saving means for clinical diagnosis or research

    Full Text Available Purpose: comparative analysis of limbs’ joints goniometric indicators of martial arts athletes; study of sportsmanship level influence on kick boxers’ movements’ amplitude. Material: martial arts athletes - students and senior pupils (n=29 participated in the research. The participants were divided into two groups. 1st group consisted of 18 kick boxers of age 17.44±0.34 years. 2nd group included 11 wrestlers of age 18.45±0.39 years. The first group was divided into two sub-groups: sub group 1a - 9 athletes of age 18.22±0.52 years and sportsmanship level: candidates and masters of sports. Sub group 1b consisted of 9 athletes, age (16.67±0.24 years and sportsmanship level from beginners to 1st sport category. We registered movements’ amplitude in wrist, shoulder, elbow, hip, knee and ankle joints. Results: we confirmed the distinctions of goniometric indicators of martial arts athletes’ limbs joints. It was found that sportsmanship level of kick-boxers influences to certain extent on movements’ amplitude. The found distinctions reflect clearly specific of kind of sports. Wrestlers have higher amplitude of movements in wrist joints that determines reliable grip in a fight. Kick boxers have better amplitude of movements in elbow and shoulder joints. It permits to punch with higher strength. The closeness of goniometric indicators of different sportsmanship kick-boxers proves equal orientation of their training. Need in constant keeping combat stance conditions reduction of in-movement amplitude in right wrist joint and outside movement in left shoulder joint of experienced athletes. Conclusions: increase of abduction in hip joint and reduction of bending in left knee joint illustrate specificities of punching/kicking, optimization of their technique in experienced athletes. The higher is training experience, the more working asymmetry of joints’ movements is.

    Plasma exchange is a non-selective apheresis technique that can be performed by filtration or centrifugation allowing rapid purification of high molecular weight pathogens. An immunosuppressive treatment is generally associated to reduce the rebound effect of the purified substance. Substitution solutes such as human albumin and macromolecules are needed to compensate for plasma extraction. Compensation by viro-attenuated plasma is reserved solely for the treatment of thrombotic microangiopathies or when there is a risk of bleeding, because this product is very allergenic and expensive. The treatment goal for a plasma exchange session should be between one and one and one-half times the patient's plasma volume estimated at 40 mL/kg body weight. The anticoagulation is best ensured by the citrate. Complications of plasma exchange are quite rare according to the French hemapheresis registry. The level of evidence of efficacy of plasma exchange in nephrology varies from one pathology to another. Main indications of plasma exchange in nephrology are Goodpasture syndrome, antineutrophil cytoplasmic antibody vasculitis when plasma creatinine is greater than 500 μmol/L, and thrombotic microangiopathies. During renal transplantation, plasma exchange may be proposed in the context of human leukocyte antigen (HLA) desensitization protocols or ABO-incompatible graft. After renal transplantation, plasma exchange is indicated as part of the treatment of acute humoral rejection or recurrent focal segmental glomerulosclerosis on the graft. Plasma exchanges are also proposed in the management of cryoglobulinemia or polyarteritis nodosa. Hemodialysis with membranes of very high permeability tends to replace plasma exchange for myeloma nephropathy. The benefit from plasma exchange has not been formally demonstrated for the treatment of severe lupus or antiphospholipid antibody syndrome. There is no indication of plasma exchange in the treatment of scleroderma or nephrogenic

    The aims of spinal deformity surgery are to achieve balance, relieve pain and prevent recurrence or worsening of the deformity. The main types of osteotomies are the Smith-Petersen osteotomy (SPO), pedicle subtraction osteotomy (PSO), bone-disc-bone osteotomy (BDBO) and vertebral column resection (VCR), in order of increasing complexity. SPO is a posterior column osteotomy in which the posterior ligaments and the facet joints are removed and correction is performed through the disc space. A mobile anterior disc is essential. SPO is best in patients with +6-8 cm C7 plumbline. The amount of correction is 9.3° to 10.7°/level (1°/mm bone). PSO is a technique where the posterior elements and pedicles are removed. Then a triangular wedge through the pedicles is removed and the posterior spine is shortened using the anterior cortex as a hinge. The ideal candidates are patients with a severe sagittal imbalance. A single level osteotomy can produce 30° 40° of correction. A single level osteotomy may restore global sagittal balance by an average of 9 cm with an upper limit of 19 cm. BDBO is an osteotomy done above and below a disc level. A BDBO provides correction rates in the range of 35° to 60°. The main indications are deformities with the disc space as the apex and severe sagittal plane deformities. VCR is indicated for rigid multi-planar deformities, sharp angulated deformities, hemivertebra resections, resectable spinal tumours, post-traumatic deformities and spondyloptosis. The main indication for a VCR is fixed coronal plane deformity. The type of osteotomy must be chosen mainly according to the aetiology, type and apex of the deformity. One may start with SPOs and may gradually advance to complex osteotomies. Cite this article: EFORT Open Rev 2017;2:73-82. DOI: 10.1302/2058-5241.2.160069 PMID:28507779

    Full Text Available Background: Cervical cancer is one of the most common cancers in women.Conization of the cervix is one of the best diagnostic and therapeutic modality in preinvasive lesion of the cervix. Methods: In this retrospective study we have evaluated the indications,complications, cytopathologic results, diagnostic and therapeutic value of 44 patients who underwent cervical conization. Results: Age of the study group ranged from 18 to 75 (mean=43.18, SD=±11.4, and their parity ranged from 0 to 10 (mean 4-5, SD=±2-3. Ten cases (22.7% were menopauses. The main indication was inability to visualize the entire T.zone (19 cases/43.2% that was more prevalent in menopauses (50%/5cases in menopauses and 41.2% /14 cases in premenopauses. Bleeding occurred in 2 cases (4.5% and urinary infection in 1 case (2.3%. The most common histologic result after conization was mild dysplasia in 23 cases (52.3%. The most common colposcopic biopsy result was moderate dysplasia in 16 cases (36.4%.The most common pap smear result was HSIL in 16 cases (36.4%. Two cases (4.5% had invasive cancer in colposcopic- biopsy: one of them had ASCUS in the pap and another one had HSIL. Four cases (9.1% had invasive cancer in histologic report: one of which had ASCUS on the pap and the others had HSIL. Conclusion: Pap smear in screening of cervical cancer are not reliable and colposcopy is more acceptable in LSIL and ASCUS. Gynecologists should develop the skill to perform an accurate knife conization because the classical indications for conization continue to be valid and it has a low complication rate.

    To evaluate the lifestyle indicators associated with cardiorespiratory fitness in adolescents from Ilhabela, São Paulo, Brazil. The sample consisted of 181 adolescents (53% male) from the Mixed Longitudinal Project on Growth, Development, and Physical Fitness of Ilhabela. Body composition (weight, height, and body mass index, or BMI), school transportation, time spent sitting, physical activity, sports, television time (TV), having a TV in the bedroom, sleep, health perception, diet, and economic status (ES) were analyzed. Cardiorespiratory fitness was estimated by the submaximal progressive protocol performed on a cycle ergometer. Linear regression models were used with the stepwise method. The sample average age was 14.8 years, and the average cardiorespiratory fitness was 42.2 mL.kg-1.min-1 (42.9 for boys and 41.4 for girls; p=0.341). In the total sample, BMI (unstandardized regression coefficient [B]=-0.03), height (B=-0.01), ES (B=0.10), gender (B=0.12), and age (B=0.03) were significantly associated with cardiorespiratory fitness. In boys, BMI, height, not playing any sports, and age were significantly associated with cardiorespiratory fitness. In girls, BMI, ES, and having a TV in the bedroom were significantly associated with cardiorespiratory fitness. Lifestyle indicators influenced the cardiorespiratory fitness; BMI, ES, and age influenced both sexes. Not playing any sports, for boys, and having a TV in the bedroom, for girls, also influenced cardiorespiratory fitness. Public health measures to improve lifestyle indicators can help to increase cardiorespiratory fitness levels.

    By combining oil tank monitoring, systems diagnostics and flame quality monitoring in an affordable system that communicates directly with dealers by telephone modem, Insight Technologies offers new revenue opportunities and the capability for a new order of customer relations to oil dealers. With co-sponsorship from New York State Energy Research and Development Authority, we have incorporated several valuable functions to a new product based on the original Flame Quality Indicator concept licensed from the US DOE`s Brookhaven National Laboratory. The new system is the Advanced Flame Quality Indicator, or AFQI. As before, the AFQI monitors and reports the intensity of the burner flame relative to a calibration established when the burner is set up at AFQI installation. Repairs or adjustments are summoned by late-night outgoing telephone calls when limits are exceeded in either direction, indicating an impending contamination or other malfunction. A independently, a pressure transducer for monitoring oil tank level and filter condition, safety lockout alarms and a temperature monitor; all reporting automatically at instructed intervals via an on-board modem to a central station PC computer (CSC). Firmware on each AFQI unit and Insight-supplied software on the CSC automatically interact to maintain a customer database for an oil dealer, an OEM, or a regional service contractor. In addition to ensuring continuously clean and efficient operation, the AFQI offers the oil industry a new set of immediate payoffs, among which are reduced outages and emergency service calls, shorter service calls from cleaner operation, larger oil delivery drops, the opportunity to stretch service intervals to as along as three years in some cases, new selling features to keep and attract customers, and greatly enhanced customer contact, quality and reliability.

    Do adversarial environmental conditions create social cohesion? We provide new answers to this question by exploiting spatial and temporal variation in exposure to earthquakes across Chile. Using a variety of methods and controlling for a number of socio-economic variables, we find that exposure to earthquakes has a positive effect on several indicators of social cohesion. Social cohesion increases after a big earthquake and slowly erodes in periods where environmental conditions are less adverse. Our results contribute to the current debate on whether and how environmental conditions shape formal and informal institutions.

    Nielsen, Jannie Jessen; Sørensen, John Dalsgaard

    . This deterioration is expected to cause larger loads, because increased play causes dynamic loads. At some point, the increased loads can be expected to cause a failure somewhere in the pitch system. If the loads increase with the size of the damage, the loads can be used as indicators of the size of the damage....... This hypothesis was supported by results from a measurement campaign where measurements were available both before and after maintenance was performed. The loads dramatically decreased after the maintenance. However, after a few more months of measurements, and by including data from the SCADA system, it became...

    1995-12-01

    Some supraventricular tachyarrhythmias (SVT), particularly if paroxysmal and/or related to Wolff-Parkinson-White syndrome (WPW), may in some cases endanger an athlete's professional career due to hemodynamic consequences during athletic activity, which in some instances may be life-threatening. One must also take into account that in Italy the law makes antiarrhythmic drug treatment (AAD) incompatible with sport eligibility. For these reasons, the utilization of radiofrequency ablation (RFA) in athletes has different indications as opposed to the normal population, since the primary goal is "the eligibility of the athlete." In our study, we discuss the criteria for indication of RFA in athletes with SVT on the basis of the data obtained from our population of athletes, studied over a 20-year period, from 1974 to the 31st of December 1993. These athletes were evaluated for arrhythmic events, utilizing a standardized cardioarrhythmological protocol: 1,325 athletes (1,125 men, 200 women, mean age 20.7 years). One subgroup included 380 athletes with WPW (28.7%), 22 athletes with aborted sudden death (1.6%), 6 of whom had WPW, 13 athletes with sudden death (0.98%), and 2 of whom had WPW. Another subgroup was formed by 116 top level elite professional athletes (TLA) (mean age 22.9 years), of which 10 of 116 (8.6%) had WPW and 12 of 116 (10.3%) had paroxysmal SVT. The most important indications for RFA in athletes are represented by: WPW asymptomatic at risk, symptomatic during athletic activity, and/or requiring AAD treatment: paroxysmal junctional reentrant tachycardia: when this condition is disabling and related to exercise and therefore compromising an athlete's performance and sports career. Paroxysmal junctional reentrant tachycardia is easily reproduced via transesophageal atrial pacing (TAP) during exercise (bicycle ergometer), common in athletes but normally the recurrences are concentrated only during the period in which the athlete is engaged in sport.

    1991-11-01

    The depolymerisation of the various chains of unfractionated heparin (UFH) by chemical or enzymatic reactions provides so-called low molecular weight heparin (LMWH), with an average molecular weight of approximately 5000 daltons. The specific biological and pharmacokinetic properties of LMWH with greater inhibition of factor Xa than of thrombin activity, less interaction with platelets, better bioavailability and a longer half life of anti-Xa activity, suggest possible new therapeutic applications. The hypothesis of reducing the risk of haemorrhage related to the antithrombin activity and the incidence of heparin-induced thrombocytopenia whilst preserving effective antithrombotic action has stimulated clinical and biological research. Clinical trials of prophylaxis of venous thrombo-embolism have been undertaken mainly in surgical patients. The results have shown identical if not better efficacy of LMWH compared to UFH in general surgical and above all orthopedic patients in whom subcutaneous heparin is only effective with a strict protocol which is difficult to adhere to in routine practice (adaptation of dosage to activated partial thromboplastin time). The risk of bleeding was not significantly lower using LMWH at the specified dosage, which in the latter indication, is twice that used in general surgery. There are many indications of prophylaxis of thromboembolism in the medical specialties but, paradoxically, LMWH has not been widely studied because of the difficulties in performing the therapeutic trials. Except in rare cases (extreme body weights, renal failure, haemorrhagic disease, thrombotic or haemorrhagic complications) the evaluation of amidolytic anti-Xa activity does not seem to be necessary. More recently, LMWH has been studied in a small number of trials for the treatment of deep venous thrombosis (DVT). The therapeutic efficacy is identical if not better than that of UFH without increasing the risk of bleeding. Biological monitoring seems to be

    2008-10-01

    Full Text Available Degree of decomposition is an important property of the organic matter in soils and other deposits which contain fossil carbon. It describes the intensity of transformation, or the humification degree (HD, of the original living organic matter. In this article, approaches to the determination of HD are thoroughly described and 14C dated peat columns extracted from several bogs in Latvia are investigated and compared. A new humification indicator is suggested, namely the quantity of humic substances as a fraction of the total amount of organic matter in the peat.

  20. Annual Journal citation indices: a comparative study

    2016-01-01

    We study the statistics of citations made to the indexed Science journals in the Journal Citation Reports during the period 2004-2013 using different measures. We consider different measures which quantify the impact of the journals. To our surprise, we find that the apparently uncorrelated measures, even when defined in an arbitrary manner, show strong correlations. This is checked over all the years considered. Impact factor being one of these measures, the present work raises the question whether it is actually a nearly perfect index as claimed often. In addition we study the distributions of the different indices which also behave similarly.

    The flame quality indicator concept was developed at BNL specifically to monitor the brightness of the flame in a small oil burner and to provide a ''call for service'' notification when the brightness has changed from its setpoint, either high or low. In prior development work BNL has explored the response of this system to operational upsets such as excess air changes, fouled atomizer nozzles, poor fuel quality, etc. Insight Technologies, Inc. and Honeywell, Inc. have licensed this technology from the U.S. Department of Energy and have been cooperating to develop product offerings which meet industry needs with an optimal combination of function and price. Honeywell has recently completed the development of the Flame Quality Monitor (FQM or Honeywell QS7100F). This is a small module which connects via a serial cable to the burners primary operating control. Primary advantages of this approach are simplicity, cost, and ease of installation. Call-for-service conditions are output in the form of front panel indicator lights and contact closure which can trigger a range of external communication options. Under this project a field test was conducted of the FQM in cooperation with service organizations in Virginia, Pennsylvania, New Jersey, New York, and Connecticut. At total of 83 field sites were included. At each site the FQM was installed in parallel with another embodiment of this concept--the Insight AFQI. The AFQI incorporates a modem and provides the ability to provide detailed information on the trends in the flame quality over the course of the two year test period. The test site population was comprised of 79.5% boilers, 13.7% warm air furnaces, and 6.8% water heaters. Nearly all were of residential size--with firing rates ranging from 0.6 gallons of oil per hour to 1.25. During the course of the test program the monitoring equipment successfully identified problems including: plugged fuel lines, fouled nozzles, collapsed combustion

    A turbine airfoil usable in a turbine engine and including a depth indicator for determining outer wall blade thickness. The airfoil may include an outer wall having a plurality of grooves in the outer surface of the outer wall. The grooves may have a depth that represents a desired outer surface and wall thickness of the outer wall. The material forming an outer surface of the outer wall may be removed to be flush with an innermost point in each groove, thereby reducing the wall thickness and increasing efficiency. The plurality of grooves may be positioned in a radially outer region of the airfoil proximate to the tip.

    Wessels Boer, J G

    1983-09-01

    Environmental protection policy strives to maintain an environment favourable to human health, agriculture, and the preservation of natural heritage. Infringements upon the environment have been either by sudden deliberate action of man (construction, land reclamation, dams, etc.) or by gradual, insipid stress of chemical and physical agents (chemical substances, heat, noise, radiation, etc.). Indeliberate unwanted stress upon the environment may be measured either by observing biological effects on indicator organisms or by chemically analyzing contaminants in these organisms. In this respect the author pleads for modest, cost-efficient monitoring programmes of limited duration and providing policy related information in a direct way. Biological effect monitoring programmes show limited prospects at this moment.

    Full Text Available Interproximal enamel reduction is a technique used for creating space in cases of mild or moderate crowding. There are several indications and contraindications determined by the tooth shape and the percentage of the caries index. The instruments used for the technique are diamond-coated metal strips, diamond discs and burs, each with advantages and disadvantages. Another way of interdental enamel reduction is using chemical products such as orthophosphoric acid. There are opposite impacts on the enamel surface and the periodontal tissues, based on the literature review.

    This clinical report illustrates with clinical cases the indications and limits of microabrasion in patients with discolored anterior teeth. The proposed techniques are based on the elimination of the dysplastic external enamel layer through microabrasion, completed by home bleaching and the use of modern adhesive restorative techniques, if necessary. In specific cases, the proposed technique may eliminate dysplastic enamel lesions without being invasive. The use of minimally invasive techniques based on microabrasion allows for treatment of slight enamel defects. In more severe cases, megabrasion combined with a minimally invasive adhesive resin composite restoration may present a valuable alternative to microabrasion.

    The indication for a mitral valve intervention is an important patient-relevant parameter for the assessment of process quality and the comparison of healthcare providers. In this article, we describe the development of a corresponding quality indicator for an external hospital quality assurance (QA) procedure in Germany. An expert panel was set up by the aQua Institute to assist with the development of a QA procedure for mitral valve interventions and the associated quality indicators. In a comprehensive, systematic literature and evidence research, the American and European guidelines were identified as the best evidence available. Especially the more current American guideline formed the basis on which a quality indicator dealing with the correct indication for a mitral valve intervention was developed. The developed quality indicator assesses the proportion of patients for whom an indication for a mitral valve intervention was determined in compliance with guideline recommendations. The indicator differentiates between surgical and catheter-based procedures. To determine whether or not the indication was correct, different medical parameters are included, such as, for example, type of mitral valve defect, etiology of the disease, severity of symptoms, valve morphology (e. g., mitral valve area), valve hemodynamics and comorbidity, which healthcare providers have to document. The documentation for the developed quality indicator is considerable. Nonetheless, its relevance is undeniable because it allows the user to determine whether a surgical or catheter-based mitral valve intervention was necessary and performed according to guideline recommendations. In the first year of its implementation, this indicator should be evaluated for further improvement and simplification of assessment. Copyright © 2017. Published by Elsevier GmbH.

The business demography statistics focusing on real enterprises population’s events (such as births and deaths is analyzed in terms of its descriptive statistical appearance in Romania to point out the divergent patterns as compared to some aggregates at the European Union level. Starting from the evidence that business dynamics revealed by the business demography statistics is a key source of information for analyzing the prospects of business and entrepreneurial activity, the paper suggests using a well known statistical measure – the z score to address the subject of the specific historical pattern in the companies’ demography in Romania. The usage of enterprise birth rates, death rates and the two-year survival rates is chosen for statistical analysis as they are part of the structural indicators used to monitor the progress of the Europe 2020 agenda. The investment rate which is one of the key indicators for economic sector is provided for the euro area and some EU state members.

  10. Characterizing relationships among fecal indicator bacteria ...

    Science.gov (United States)

    Bed sediments of streams and rivers may store high concentrations of fecal indicator bacteria (FIB) and pathogens. Due to resuspension events, these contaminants can be mobilized into the water column and affect overall water quality. Other bacterial indicators such as microbial source tracking (MST) markers, developed to determine potential sources of fecal contamination, can also be resuspended from bed sediments. The primary objective of this study was to predict occurrence of waterborne pathogens in water and streambed sediments using a simple statistical model that includes traditionally measured FIB, environmental parameters and source allocation, using MST markers as predictor variables. Synoptic sampling events were conducted during baseflow conditions downstream from agricultural (AG), forested (FORS), and wastewater pollution control plant (WPCP) land uses. Concentrations of FIB and MST markers were measured in water and sediments, along with occurrences of the enteric pathogens Campylobacter, Listeria and Salmonella, and the virulence gene that carries Shiga toxin, stx2. Pathogens were detected in water more often than in underlying sediments. Shiga toxin was significantly related to land use, with concentrations of the ruminant marker selected as an independent variable that could correctly classify 76% and 64% of observed Shiga toxin occurrences in water and sediment, respectively. FIB concentrations and water quality parameters were also selected a

    Data from the Atacama Cosmology Telescope (ACT) and the South Pole Telescope (SPT), combined with the nine-year data release from the WMAP satellite, provide very precise measurements of the cosmic microwave background (CMB) angular anisotropies down to very small angular scales. Augmented with measurements from Baryonic Acoustic Oscillations surveys and determinations of the Hubble constant, we investigate whether there are indications for new physics beyond a Harrison-Zel'dovich model for primordial perturbations and the standard number of relativistic degrees of freedom at primordial recombination. All combinations of datasets point to physics beyond the minimal Harrison-Zel'dovich model in the form of either a scalar spectral index different from unity or additional relativistic degrees of freedom at recombination (e.g., additional light neutrinos). Beyond that, the extended datasets including either ACT or SPT provide very different indications: while the extended-ACT (eACT) dataset is perfectly consistent with the predictions of standard slow-roll inflation, the extended-SPT (eSPT) dataset prefers a non-power-law scalar spectral index with a very large variation with scale of the spectral index. Both eACT and eSPT favor additional light degrees of freedom on top of the Harrison-Zel'dovich model. eACT is consistent with zero neutrino masses, while eSPT favors nonzero neutrino masses at more than 95% confidence.

    Full Text Available ABSTRACT Growth regulator in oat can reduce lodging with effects on yield indicators. The objective of the study is to define the optimum dose of growth regulator to reduce lodging in oats under different conditions of nitrogen (N fertilization (reduced, high and very high and the effects on yield indicators in the succession systems. In each succession system (soybean/oats and corn/oats, two experiments were conducted, one to quantify biomass yield and the other to estimate grain yield and lodging. In the four experiments, the design was randomized blocks with four replicates in 3 x 4 factorial scheme, for N-fertilizer doses (30, 90 and 150 kg ha-1 and growth regulator doses (0, 200, 400 and 600 mL ha-1, respectively. Growth regulator reduces lodging in oat plants, with the ideal doses of 500 mL ha-1 in the soybean/oat system and 400 mL ha-1 in the corn/oat system, regardless of the reduced, high and very high N doses. There is a linear reduction of biological and straw yields, and a quadratic trend in the expression of grain yield and harvest index as a function of the growth regulator doses, regardless of succession systems (soybean/oats and corn/oats.

    Full Text Available In this paper, we apply multidimensional scaling (MDS and parametric similarity indices (PSI in the analysis of complex systems (CS. Each CS is viewed as a dynamical system, exhibiting an output time-series to be interpreted as a manifestation of its behavior. We start by adopting a sliding window to sample the original data into several consecutive time periods. Second, we define a given PSI for tracking pieces of data. We then compare the windows for different values of the parameter, and we generate the corresponding MDS maps of ‘points’. Third, we use Procrustes analysis to linearly transform the MDS charts for maximum superposition and to build a globalMDS map of “shapes”. This final plot captures the time evolution of the phenomena and is sensitive to the PSI adopted. The generalized correlation, theMinkowski distance and four entropy-based indices are tested. The proposed approach is applied to the Dow Jones Industrial Average stock market index and the Europe Brent Spot Price FOB time-series.

    The relationship between frequency of consumption of a selected number of indicator foods and oral and oropharyngeal cancer risk was analysed in a case-control study conducted in Northern Italy on 105 cases of oral and pharyngeal cancer and 1169 controls in hospital for acute, non-neoplastic or digestive diseases. Besides significant and strong direct associations with tobacco (relative risk, RR = 11.0 for current versus never smokers) and alcohol (RR = 5.8 for upper versus lower consumption tertile), consumption of six food items (milk, meat, cheese, carrots, green vegetables and fruit) were inversely and significantly related to oral and pharyngeal cancer risk. The strongest protection was apparently related to frequent fruit consumption, with RRs of 0.8 and 0.2 in the two highest tertiles. Allowance for major potential confounding factors, including tobacco, alcohol and social class indicators explained only part of the dietary correlates observed. The two items remaining significant after multivariate analysis were fruit (RR = 0.3 for the upper tertile) and alcohol (RR = 3.8 for the upper tertile). The associations observed may simply reflect a generally poorer nutritional status in the cases, although the observation that fruit consumption appears to be a particularly important protective factor against oropharyngeal cancer is of potential interest, in terms of aetiological clues and preventive implications.

    To define a set of dietary components that are relevant determinants for health in Europe. The selected components are intended to serve as nutrition indicators for health in the European Health Monitoring Programme and, as such, must be limited in number, relevant to health in Europe and practical for all involved countries with respect to data gathering and comparability of data. Major nutrition factors were determined by reviewing relevant epidemiological and clinical literature in nutrition and health as well as referring to reports from international expert groups, including the report from the project Nutrition and Diet for Healthy Lifestyles in Europe. The selection of factors was also based on the relative ease and cost involved for participating countries to obtain comparable and valid data. The selected factors include foods or food groups as well as individual nutrients. Biomarkers are suggested for selected nutrients that pose the greatest difficulty in obtaining valid and comparable data from dietary studies. The following list of diet indicators for health monitoring in Europe was agreed upon by the EFCOSUM group in 2001, in order of priority: vegetables, fruit, bread, fish, saturated fatty acids as percentage of energy (%E), total fat as %E, and ethanol in grams per day. Biomarkers were suggested for the following nutrients: folate, vitamin D, iron, iodine and sodium. Energy has to be assessed in order to calculate %E from total fat and saturated fatty acids.

    Quandalle, P; Gambiez, L; Colombel, J F; Cortot, A; Paris, J C; Saudemont, A; Chambon, J P

    Indications for surgery in Crohn's disease were studied in 100 consecutive cases. Cases included emergency situations (n = 22) complicated forms (n = 55) and chronic forms (n = 23). Lesions were located in the small bowel alone (n = 43), small and large bowel (n = 16) and in the colon and rectum (n = 16). During the same period, 26 reoperations were performed, there was no operative mortality and no short bowels were observed. A stomy was required in 30 cases and could be removed in 19. For lesions involving the small bowel, resections were limited to symptomatic lesions; long and short plasties were performed with no complications. For the colon, total and segmentary colectomy was performed for 18 cases and ileorectal anastomoses in 13. Five proctectomies were required. Rectal exclusion was considered as a wait and see solution which was long in several cases with severe rectoperineal lesions. In these cases, secondary proctectomy should be widely proposed. For emergency situations, it would be prudent to use a safe operative technique with wide indication for stomies. For complicated forms, careful preparation allows for complete procedure with one operation. For chronic forms resistant to medical treatment, the decision can be rather difficult, but the fact that recurrences do exist should not mask the long-term remissions obtained in half the cases with surgery.

    Acupuncture is a medical procedure with a very wide range of indications according to the WHO. However the indications require robust scientific evidence to support them. We have conducted a systematic review (2010-2015) in order to define in which pathologies acupuncture can be an effective strategy, STRICTA criteria that aim to set up acupuncture clinical trials standard criteria were defined in 2010. Only systematic reviews and meta-analyses of good or very good methodological quality according to SIGN criteria were selected. Its main objective was to evaluate the effectiveness of acupuncture in the management of any disease. Most of the final 31 selected reviews focus on chronic pain-related diseases, mainly in the disciplines of Neurology, Orthopaedics and Rheumatology. Current evidence supports the use of acupuncture in the treatment of headaches, migraines, back pain, cervical pain and osteoarthritis. The remaining pathologies still require further good quality studies. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    Liver volumetry has emerged as an important tool in clinical practice. Liver volume is assessed primarily via organ segmentation of computed tomography (CT) and magnetic resonance imaging (MRI) images. The goal of this paper is to provide an accessible overview of liver segmentation targeted at radiologists and other healthcare professionals. Using images from CT and MRI, this paper reviews the indications for liver segmentation, technical approaches used in segmentation software and the developing roles of liver segmentation in clinical practice. Liver segmentation for volumetric assessment is indicated prior to major hepatectomy, portal vein embolisation, associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and transplant. Segmentation software can be categorised according to amount of user input involved: manual, semi-automated and fully automated. Manual segmentation is considered the "gold standard" in clinical practice and research, but is tedious and time-consuming. Increasingly automated segmentation approaches are more robust, but may suffer from certain segmentation pitfalls. Emerging applications of segmentation include surgical planning and integration with MRI-based biomarkers. Liver segmentation has multiple clinical applications and is expanding in scope. Clinicians can employ semi-automated or fully automated segmentation options to more efficiently integrate volumetry into clinical practice. • Liver volume is assessed via organ segmentation on CT and MRI examinations. • Liver segmentation is used for volume assessment prior to major hepatic procedures. • Segmentation approaches may be categorised according to the amount of user input involved. • Emerging applications include surgical planning and integration with MRI-based biomarkers.

  19. Environmental policy indicators: A systems model

    Cummings, Leslie Edwards; Cayer, N. Joseph

    1993-09-01

    This article describes and tests a systems theory-based policy indicators model. The framework is used to examine propositions about linkages between states' ecological-spatial characteristics and subsequent selected solid waste management (SWM) -related environmental policies. It was hypothesized that state characteristics of: (1) population density (used as a garbage-per-land area index), (2) population convergence within urban areas, and (3) percent population change in the interval 1980 1985, could jointly explain state variation in both the number and the vigor of SWM policy outputs. Greater levels of spatial pressure were proposed to be related directly to more numerous, more convincing policies. Proposals are grounded in the literature of organizational search theory, crisis stimulation, and technological pressure. Results revealed that the sociospatial model in fact could explain a reasonable proportion of policy variation across states. However, not all hypotheses are supported. Population change shows an indirect, rather than the anticipated direct, relationship with policy output levels. In addition, when used in the model as a pollution intensity index, population density failed to contribute significantly to an explanation of differences in state SWM policy levels. The analysis raises questions about changes occurring over time in the nature and direction of linkages between sociospatial measures and policy responses. This study suggests that strengthening policy indicator models may require questioning key assumptions and theoretical bases, conducting longitudinal studies, and factoring in political, economic, and other policy environment forces.

    2009-02-01

    Human perception of material colors depends heavily on the nature of the light sources used for illumination. One and the same object can cause highly different color impressions when lit by a vapor lamp or by daylight, respectively. Based on state-of-the-art colorimetric methods we present a modern approach for calculating color rendering indices (CRI), which were defined by the International Commission on Illumination (CIE) to characterize color reproduction properties of illuminants. We update the standard CIE method in three main points: firstly, we use the CIELAB color space, secondly, we apply a Bradford transformation for chromatic adaptation, and finally, we evaluate color differences using the CIEDE2000 total color difference formula. Moreover, within a real-world scene, light incident on a measurement surface is composed of a direct and an indirect part. Neumann and Schanda1 have shown for the cube model that interreflections can influence the CRI of an illuminant. We analyze how color rendering indices vary in a real-world scene with mixed direct and indirect illumination and recommend the usage of a spectral rendering engine instead of an RGB based renderer for reasons of accuracy of CRI calculations.

  1. Are there still indications for total pancreatectomy?

    2016-09-01

    Total pancreatectomy is associated with short- and long-term high complication rate and without evidence of oncologic advantages. Several metabolic consequences are co-related with the apancreatic state. The unstable diabetes related to the total resection of the pancreas expose the patients to short- and long-term life-threatening complications. Severe hypoglycemia is a short-term dangerous complication that can also cause patients' death. Chronic complications of severe diabetes (cardiac and vascular diseases, neuropathy, nephropathy, and retinopathy) are also cause of morbidity, mortality and worsening of quality of life. For this reasons the number of total pancreatectomies performed has certainly decreased over time. However, today there are still some indications for this kind of procedures. Chronic pancreatitis untreatable with conventional treatments, surgical treatment of precancerous pancreatic lesions, surgical treatment of locally advanced pancreatic cancer and the management of patients with extraordinary high-risk pancreatic texture after pancreaticoduodenectomy represent possible indications for total pancreatectomy and are analyzed in the present paper.

    2012-02-01

    INTRODUCTION: The purpose of this study was to evaluate the utility of imaging examinations in patients with elevated tumour markers when (a) the tumour marker is not validated for as a primary diagnostic test; (b) the patient had no personal history of cancer and (c) the patient had no other imaging indication. MATERIALS AND METHODS: Patients without known cancer who had abnormal carcinoembryonic antigen, CA19-9, CA125 and\\/or CA15-3 serology over a one-year period were included. A retrospective medical record review was performed to assess the number of these cases who underwent imaging because of \\'elevated tumour marker\\' in the absence of a clinical indication for imaging. The number and result of these imaging studies were evaluated. RESULTS: Eight hundred and nineteen patients were included. Of those, 25 patients (mean age: 67.8 [range 41-91] y), were imaged to evaluate: \\'elevated tumour marker\\'. They underwent 29 imaging studies (mean [+\\/-standard deviation (SD)] per patient = 1.2 [+\\/-0.4]), and had 42 elevated tumour marker serology tests (mean [+\\/-SD] per patient = 1.7 [+\\/-0.7]). Four patients had >1 imaging test. No patient had an imaging study which diagnosed a malignancy or explained the elevated tumour marker. CONCLUSION: The non-judicious use of tumour markers can prompt further unnecessary investigations including imaging. In this study, there was no positive diagnostic yield for imaging performed for investigation of \\'elevated tumour marker\\'. \\'Elevated tumour marker\\

QIs are intended to characterize quality of care delivered in a facility. Threats to the validity of the measurement of presumed quality of care include baseline resident health and functional status, pattern of comorbidities, and facility case mix. The goal of obtaining a valid facility-level estimate of true quality of care should include adjustment for resident- and facility-level sources of variability. Methods We present a practical and efficient method to achieve risk adjustment using restriction and indirect and direct standardization. We present information on validity by comparing QIs estimated with the new algorithm to one currently used by CMS. Results More than half of the new QIs achieved a "Moderate" validation level. Conclusions Given the comprehensive approach and the positive findings to date, research using the new quality indicators is warranted to provide further evidence of their validity and utility and to encourage their use in quality improvement activities.

    HCV Infection is a global burden disease and it is related to the development of progressive liver fibrosis, cirrhosis and hepatocellular carcinoma. At least 80% of the persons that have an acute infection evolve to chronicity. This event affects the patient and their contacts for the risk of acquiring the infection. Once chronic HCV is present some factors accelerate progression: older age, obesity, alcohol consumption, etc. Severity of fibrosis is one of the most important factors to be analyzed before deciding to treat a patient. Pegylated interferon and ribavirin is the .standard of care. for this disease, however, it has many side effects, some of them life threatening. That is the reason why this treatment must be indicated in the right moment in the right patient. A complete medical evaluation must be done previously to initiate treatment. Other concurrent problems must be ruled out or treated. Decompensated cirrhosis, autoimmune diseases or other uncontrolled disease are contraindication to HCV treatment. Previous failure to treatment for HCV must be analyzed to identify the reasons for that event and consider retreatment. Cryoglobulinemia and membranoproliferative glomerulonephritis are indications for treatment independent from the severity of liver disease.

Initially, 13 active teams were formed to recommend indicators in a range of categories, including...

  6. Climate change or land use dynamics: do we know what climate change indicators indicate?

    Directory of Open Access Journals (Sweden)

    Miguel Clavero

    Full Text Available Different components of global change can have interacting effects on biodiversity and this may influence our ability to detect the specific consequences of climate change through biodiversity indicators. Here, we analyze whether climate change indicators can be affected by land use dynamics that are not directly determined by climate change. To this aim, we analyzed three community-level indicators of climate change impacts that are based on the optimal thermal environment and average latitude of the distribution of bird species present at local communities. We used multiple regression models to relate the variation in climate change indicators to: i environmental temperature; and ii three landscape gradients reflecting important current land use change processes (land abandonment, fire impacts and urbanization, all of them having forest areas at their positive extremes. We found that, with few exceptions, landscape gradients determined the figures of climate change indicators as strongly as temperature. Bird communities in forest habitats had colder-dwelling bird species with more northern distributions than farmland, burnt or urban areas. Our results show that land use changes can reverse, hide or exacerbate our perception of climate change impacts when measured through community-level climate change indicators. We stress the need of an explicit incorporation of the interactions between climate change and land use dynamics to understand what are current climate change indicators indicating and be able to isolate real climate change impacts.

    Bacterial communities are important for the health and productivity of soil ecosystems and have great potential as novel indicators of environmental perturbations. To assess how they are affected by anthropogenic activity and to determine their ability to provide alternative metrics of environmental health, we sought to define which soil variables bacteria respond to across multiple soil types and land uses. We determined, through 16S rRNA gene amplicon sequencing, the composition of bacterial communities in soil samples from 110 natural or human-impacted sites, located up to 300 km apart. Overall, soil bacterial communities varied more in response to changing soil environments than in response to changes in climate or increasing geographic distance. We identified strong correlations between the relative abundances of members of Pirellulaceae and soil pH, members of Gaiellaceae and carbon-to-nitrogen ratios, members of Bradyrhizobium and the levels of Olsen P (a measure of plant available phosphorus), and members of Chitinophagaceae and aluminum concentrations. These relationships between specific soil attributes and individual soil taxa not only highlight ecological characteristics of these organisms but also demonstrate the ability of key bacterial taxonomic groups to reflect the impact of specific anthropogenic activities, even in comparisons of samples across large geographic areas and diverse soil types. Overall, we provide strong evidence that there is scope to use relative taxon abundances as biological indicators of soil condition. The impact of land use change and management on soil microbial community composition remains poorly understood. Therefore, we explored the relationship between a wide range of soil factors and soil bacterial community composition. We included variables related to anthropogenic activity and collected samples across a large spatial scale to interrogate the complex relationships between various bacterial community attributes and

  8. Technical and Ethical Issues in Indicator Systems

    Directory of Open Access Journals (Sweden)

    2002-01-01

    Full Text Available Most indicator systems are top-down, published, management systems, addressing primarily the issue of public accountability. In contrast we describe here a university-based suite of "grass-roots," research-oriented indicator systems that are now subscribed to, voluntarily, by about 1 in 3 secondary schools and over 4,000 primary schools in England. The systems are also being used by groups in New Zealand, Australia and Hong Kong, and with international schools in 30 countries. These systems would not have grown had they not been cost-effective for schools. This demanded the technical excellence that makes possible the provision of one hundred percent accurate data in a very timely fashion. An infrastructure of powerful hardware and ever-improving software is needed, along with extensive programming to provide carefully chosen graphical and tabular presentations of data, giving at-a-glance comparative information. Highly skilled staff, always learning new techniques, have been essential, especially as we move into computer-based data collection. It has been important to adopt transparent, readily understood methods of data analysis where we are satisfied that these are accurate, and to model the processes that produce the data. This can mean, for example, modelling separate regression lines for 85 different examination syllabuses for one age group, because any aggregation can be shown to represent unfair comparisons. Ethical issues are surprisingly often lurking in technical decisions. For example, reporting outcomes from a continuous measure in terms of the percent of students who surpassed a certain level, produces unethical behavior: a concentration of teaching on borderline students. Distortion of behavior and data corruption are ever-present concerns in indicator systems. The systems we describe would have probably failed to thrive had they not addressed schools' on-going concerns about education. Moreover, data interpretation can only be

  9. Comparing wastewater chemicals, indicator bacteria concentrations, and bacterial pathogen genes as fecal pollution indicators

    The objective of this study was to compare fecal indicator bacteria (FIB) (fecal coliforms, Escherichia coli [EC], and enterococci [ENT]) concentrations with a wide array of typical organic wastewater chemicals and selected bacterial genes as indicators of fecal pollution in water samples collected at or near 18 surface water drinking water intakes. Genes tested included esp (indicating human-pathogenic ENT) and nine genes associated with various animal sources of shiga-toxin-producing EC (STEC). Fecal pollution was indicated by genes and/or chemicals for 14 of the 18 tested samples, with little relation to FIB standards. Of 13 samples with <50 EC 100 mL-1, human pharmaceuticals or chemical indicators of wastewater treatment plant effluent occurred in six, veterinary antibiotics were detected in three, and stx1 or stx2 genes (indicating varying animal sources of STEC) were detected in eight. Only the EC eaeA gene was positively correlated with FIB concentrations. Human-source fecal pollution was indicated by the esp gene and the human pharmaceutical carbamazepine in one of the nine samples that met all FIB recreational water quality standards. Escherichia coli rfbO157 and stx2c genes, which are typically associated with cattle sources and are of potential human health significance, were detected in one sample in the absence of tested chemicals. Chemical and gene-based indicators of fecal contamination may be present even when FIB standards are met, and some may, unlike FIB, indicate potential sources. Application of multiple water quality indicators with variable environmental persistence and fate may yield greater confidence in fecal pollution assessment and may inform remediation decisions.

  10. Aligning Organizational Pathologies and Organizational Resilience Indicators

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available Developing resilient individuals, organizations and communities is a hot topic in the research agenda in Management, Ecology, Psychology or Engineering. Despite the number of works that focus on resilience is increasing, there is not completely agreed definition of resilience, neither an entirely formal and accepted framework. The cause may be the spread of research among different fields. In this paper, we focus on the study of organizational resilience with the aim of improving the level of resilience in organizations. We review the relation between viable and resilient organizations and their common properties. Based on these common properties, we defend the application of the Viable System Model (VSM to design resilient organizations. We also identify the organizational pathologies defined applying the VSM through resilience indicators. We conclude that an organization with any organizational pathology is not likely to be resilient because it does not fulfill the requirements of viable organizations.

    Aspirin (acetylsalicylic acid) has been used ever since the Antiquity for its painkilling and anti-inflammatory effects. Its antiplatelet properties have then extended its indications to the field of coronaropathy and vascular cerebral disease, and finally to vascular placental disease. Aspirin has been widely prescribed since the 1980's to prevent pre-eclampsia, intra-uterine growth retardation and fetal death of vascular origin. It has also been proposed to prevent unexplained recurrent miscarriages. Its use during pregnancy is considered as safe, provided the daily doses do not exceed 100mg. Aspirin has been proven efficient to prevent pre-eclampsia and fetal growth restriction in high-risk patients. The benefits of prescribing aspirin have been demonstrated neither for vascular placental disease prevention in low risk patients, nor in cases of unexplained recurrent miscarriages.

  12. Pancreatic sphincterotomy: technique, indications, and complications.

    Buscaglia, Jonathan M; Kalloo, Anthony N

    2007-08-14

    Pancreatic sphincterotomy serves as the cornerstone of endoscopic therapy of the pancreas. Historically, its indications have been less well-defined than those of endoscopic biliary sphincterotomy, yet it plays a definite and useful role in diseases such as chronic pancreatitis and pancreatic-type sphincter of Oddi dysfunction. In the appropriate setting, it may be used as a single therapeutic maneuver, or in conjunction with other endoscopic techniques such as pancreatic stone extraction or stent placement. The current standard of practice utilizes two different methods of performing pancreatic sphincterotomy: a pull-type sphincterotome technique without prior stent placement, and a needle-knife sphincterotome technique over an existing stent. The complications associated with pancreatic sphincterotomy are many, although acute pancreatitis appears to be the most common and the most serious of the early complications. As such, it continues to be reserved for those endoscopists who perform a relatively high-volume of therapeutic pancreaticobiliary endoscopic retrograde cholangio-pancreatography.

  13. Core inflation indicators for Saudi Arabia

    Alkhareif Ryadh M.

    2015-01-01

    Full Text Available This paper constructs and analyzes core inflation indicators for Saudi Arabia for the period of March 2012 to May 2014 using two alternative approaches: the exclusion method (ex food and housing/rent and the statistical method. The findings of the analysis suggest that the ex food and housing/ rent inflation is more volatile than the overall CPI inflation over the sample period. In contrast, the statistical core inflation is relatively more stable and less volatile. Moreover, the ex food and housing/rent inflation is only weakly correlated with headline inflation, whereas the statistical core inflation exhibits a stronger correlation. This combination of lower volatility and higher correlation with headline inflation makes the statistical method a much better choice for policymakers. From a monetary policy standpoint, using a bundle of core inflation measures, including both properly constructed exclusion and statistical methods, is more desirable, especially when variation across measures is widespread, as is the case in Saudi Arabia.

    Thermochromic semiconductive polymers that change color in response to external stimuli, such as heat and radiation, can be utilized to monitor the temperature range and elapsed time profiles of stored and prepositioned munitions. These polymers are being tailored to create paints and coatings that will alert Army logistic staff of dangerous temperature exposures. Irreversible indication via color change in multiple thermal bands, 145 F - 164 F (63o-73°C), 165 F - 184 F (74° - 84° C) and over 185 F (>85°C) are possible with these thermochromic polymers. The resulting active coating can be visually inspected to determine if safe temperatures were exceeded. More detailed information, including cumulative time of exposure in certain temperature bands through changes in optical chromaticity describing the vividness or dullness of a color, can be assessed using a hand-held optical densitometer.

    define sustainability, in other words, the maintenance of their functions inside the limits of an ecosystem. The health and quality indicators are a set of measurements (physical, chemical and biological properties that pretend to establish quality standards for this resource; the enzymatic activity is placed inside this set because of its close relationship with the other properties and because of its sensibleness to the changes due to handling and use. The present review pretends to illustrate how the tracking of the biological catalysis of the soil through uses and alterations that an ecosystem may suffer, may supply information for the understanding of how the processes responsible for the maintenance of functions such as biomass production, pollutant remediation and cycling of nutrients, suffer changes and if these are positive, negative or iterative.

    Montelukast is recommended for the treatment of asthma, exercise -induced bronchospasm and allergic rhinitis. Several trials demonstrated potential therapeutic effects in other respiratory conditions, and different animal-model-based studies explored potential pharmacological actions in non-respiratory conditions. Clinical investigations on the pharmacotherapeutic effects of montelukast, in addition to in-vivo studies on animal models of non-respiratory diseases. The data discussed in this review were mainly obtained from clinical randomized trials, real-life studies, and studies based on animal models as approve of concept. As a condition, all of the discussed articles were published in journals cited by Pubmed. Expert commentary: The current clinical data are in favor of montelukast use in the management of chronic asthma as an add-on or alternative therapy to the inhaled corticosteroids. Further clinical trials are required to confirm the effectiveness and feasibility of montelukast for the treatment of conditions other than the current clinical indications.

    Full Text Available This article is an analysis of public debt, in terms of sustainability and vulnerability indicators, under a functioning market economy. The problems encountered regarding the high level of public debt or the potential risks of budgetary pressure converge to the idea that sustainability of public finances should be a major challenge for public policy. Thus, the policy adequate to address public finance sustainability must have as its starting point the overall strategy of the European Union, as well as the economic development of Member States, focusing on the most important performance components, namely, reducing public debt levels, increasing productivity and employment and, last but not the least, reforming social security systems. In order to achieve sustainable levels of public debt, the European Union Member States are required to establish and accomplish medium term strategic budgetary goals to ensure a downward trend in public debt.

    Full Text Available Stock market prediction is an important area of financial forecasting, which attracts great interest to stock buyers and sellers, stock investors, policy makers, applied researchers, and many others who are involved in the capital market. In this paper, a comparative study has been conducted to predict stock index values using soft computing models and time series model. Paying attention to the applied econometric noises because our considered series are time series, we predict Chittagong stock indices for the period from January 1, 2005 to May 5, 2011. We have used well-known models such as, the genetic algorithm (GA model and the adaptive network fuzzy integrated system (ANFIS model as soft computing forecasting models. Very widely used forecasting models in applied time series econometrics, namely, the generalized autoregressive conditional heteroscedastic (GARCH model is considered as time series model. Our findings have revealed that the use of soft computing models is more successful than the considered time series model.

    A group of 86 volunteers was examined on each working day in autumn 2001 and in spring 2002. Systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were registered. Pulse pressure (PP) was calculated. Data about subjective psycho-physiological complaints (SPPC) were also gathered. Altogether 2799 recordings were obtained. ANOVA was employed to check the significance of influence of daily amplitude of H-component of local geomagnetic field, daily planetary Ap-index and hourly planetary Dst-index on the physiological parameters examined. Post hoc analysis was performed to elicit the significance of differences in the factors levels. Average values of SBP, DBP, PP and SPPC of the group were found to increase statistically significantly and biologically considerably with the increase of geomagnetic indices.

    Much attention has been devoted to the physiological changes that occur during bed rest. However, there has been a lack of focus on the psychological aspects per se. We investigated indices of psychological strain during three 10-d interventions, designed to assess the combined effects of inactivity/unloading and normobaric hypoxia on several physiological systems. Eleven male participants underwent three 10-d campaigns in a randomized manner: 1) normobaric hypoxic ambulatory confinement (HAMB), 2) normobaric hypoxic bed rest (HBR) and 3) normoxic bed rest (NBR). The most negative psychological profile appeared on BR10 of HBR and HAmb conditions (hypoxic conditions). Concomitantly a decrease in positive emotions was observed from BR-2 to BR10. Bed rest and exposure to hypoxic environments seems to exert a negative effect on person’s psychological mood.

En ella se describen los objetivos del proyecto, las gestiones realizadas y los resultados obtenidos durante la fase de viabilidad de este proyecto. El proyecto consiste en el establecimiento de un sistema de información sobre salud ambiental que permita desarrollar una vigilancia de los factores ambientales determinantes de los estados de salud, realizar comparaciones internacionales, elaborar políticas de acción, así como facilitar la comunicación con la ciudadanía. La OMS desarrolló una metodología para el desarrollo de estos indicadores dentro del marco conceptual de información ambiental DPSEEA (Fuerzas impulsoras, Presión, Estado, Exposición, Efecto, Acción y seleccionó un total de 55 indicadores (que incluyen 168 variables sobre 10 áreas de la salud ambiental. Durante la fase de viabilidad se predijo que podrían obtenerse el 89% de los indicadores. Sin embargo la recolección de los datos supuso muchas dificultades debido a la incompatibilidad de algunas variables en los sistemas de información españoles con las variables definidas por la OMS. A nivel de gestión del proyecto, la mayor dificultad radica en la disparidad de responsabilidades en materia de medio ambiente y salud entre las instituciones españolas. Además de la aportación técnica a la salud ambiental en España, un valor añadido de este proyecto ha sido el establecimiento de líneas de colaboración estrechas con los responsables de los diferentes Ministerios implicados.This presentation gives a general overview of the project titled Environmental Health Indicators, coordinated by WHO and managed by the Research Centre on the Toxic Oil Syndrome and Rare Diseases in Spain.

    Ambulatory nursing care can be difficult to comprehend in all its complexity. In August 2013, the American Academy of Ambulatory Care Nursing commissioned a task force to identify nursing-sensitive indicators specific to ambulatory care settings. Given the great variation in settings, staff mix, patient populations, role dimensions, skill sets, documentation systems, and resources, determining metrics that apply across the entire continuum of care is a daunting task. However, it is incumbent upon nurse leaders to define the metrics that will promote the value of the registered nurse in ambulatory practice and care coordination. Once initial measures are identified, piloted, and validated, the infrastructure can be created for ongoing benchmarking and collaboration. The long-term goal is to leverage professional nursing practice, based in the ambulatory care setting, to improve quality, safety, and cost in health care.

  5. Using inverted indices for accelerating LINGO calculations.

    Kristensen, Thomas G; Nielsen, Jesper; Pedersen, Christian N S

    2011-03-28

    The ever growing size of chemical databases calls for the development of novel methods for representing and comparing molecules. One such method called LINGO is based on fragmenting the SMILES string representation of molecules. Comparison of molecules can then be performed by calculating the Tanimoto coefficient, which is called LINGOsim when used on LINGO multisets. This paper introduces a verbose representation for storing LINGO multisets, which makes it possible to transform them into sparse fingerprints such that fingerprint data structures and algorithms can be used to accelerate queries. The previous best method for rapidly calculating the LINGOsim similarity matrix required specialized hardware to yield a significant speedup over existing methods. By representing LINGO multisets in the verbose representation and using inverted indices, it is possible to calculate LINGOsim similarity matrices roughly 2.6 times faster than existing methods without relying on specialized hardware.

    ISO 15189:2012 requires the use of quality indicators (QIs) to monitor and evaluate all steps of the total testing process, but several difficulties dissuade laboratories from effective and continuous use of QIs in routine practice. An International Federation of Clinical Chemistry and Laboratory Medicine working group addressed this problem and implemented a project to develop a model of QIs to be used in clinical laboratories worldwide to monitor and evaluate all steps of the total testing process, and decrease error rates and improve patient services in laboratory testing. All laboratories are invited, at no cost, to enroll in the project and contribute to harmonized management at the international level. Copyright © 2016 Elsevier Inc. All rights reserved.

  8. Quantifying landscape resilience using vegetation indices

    Eddy, I. M. S.; Gergel, S. E.

    Landscape resilience refers to the ability of systems to adapt to and recover from disturbance. In pastoral landscapes, degradation can be measured in terms of increased desertification and/or shrub encroachment. In many countries across Central Asia, the use and resilience of pastoral systems has changed markedly over the past 25 years, influenced by centralized Soviet governance, private property rights and recently, communal resource governance. In Kyrgyzstan, recent governance reforms were in response to the increasing degradation of pastures attributed to livestock overgrazing. Our goal is to examine and map the landscape-level factors that influence overgrazing throughout successive governance periods. Here, we map and examine some of the spatial factors influencing landscape resilience in agro-pastoral systems in the Kyrgyzstan Republic where pastures occupy >50% of the country's area. We ask three questions: 1) which mechanisms of pasture degradation (desertification vs. shrub encroachment), are detectable using remote sensing vegetation indices?; 2) Are these degraded pastures associated with landscape features that influence herder mobility and accessibility (e.g., terrain, distance to other pastures)?; and 3) Have these patterns changed through successive governance periods? Using a chronosequence of Landsat imagery (1999-2014), NDVI and other VIs were used to identify trends in pasture condition during the growing season. Least-cost path distances as well as graph theoretic indices were derived from topographic factors to assess landscape connectivity (from villages to pastures and among pastures). Fieldwork was used to assess the feasibility and accuracy of this approach using the most recent imagery. Previous research concluded that low herder mobility hindered pasture use, thus we expect the distance from pasture to village to be an important predictor of pasture condition. This research will quantify the magnitude of pastoral degradation and test

  9. Substorm behavior of the auroral electrojet indices

    J. W. Gjerloev

    2004-06-01

    Full Text Available The behavior of the auroral electrojet indices AU and AL during classical substorms is investigated by the use of global auroral images. A superposition of the 12 AE stations onto global auroral images and identification of the AL and AU contributing stations enable an understanding of the temporal as well as spatial behavior of the indices with respect to the substorm coordinate system and timeframe. Based on this simple technique it was found that at substorm onset the AL contributing station makes a characteristic jump from a location near the dawn terminator to the onset region, typically bypassing one or more AE stations. During the expansion phase this station typically lies at the poleward edge of the surge region. This is the location of the intense substorm current wedge electrojet in the semiempirical self-consistent substorm model of the three-dimensional current system by Gjerloev and Hoffman (2002. This current wedge is fed primarily pre-midnight by an imbalance of the Region 0 and Region 1 field-aligned currents, not from the dawnside westward electrojet. Then during the early recovery phase the AL contributing station jumps back to the dawn sector. The defining AU station does not show any similar systematic behavior. We also find that the dawn side westward electrojet seems to be unaffected by the introduction of the substorm current wedge. According to our model, much of this current is closed to the magnetosphere as it approaches midnight from dawn. Based on the characteristics of the AL station jumps, the behavior of the dawn-side electrojet, and the understanding of the three-dimensional substorm current system from our model, we provide additional experimental evidence for, and an understanding of, the concept of the two component westward electrojet, as suggested by Kamide and Kokubun (1996.

    The Canadian Heart Health Strategy and Action Plan recommended that the Canadian Cardiovascular Society (CCS) lead the development of pan-Canadian data definitions and quality indicators (QIs) for evaluating cardiovascular care in Canada. In response to this recommendation, the CCS developed and adopted a standardized QI development methodology. This report provides a brief overview of the CCS "Best Practices" for developing pan-Canadian cardiovascular QIs. A more detailed description is available in Supplemental Material. The CCS Best Practices QI development methodology consists of 3 phases: phase I, plan and organize the QI development initiative; phase II, develop and select QIs; and phase III, operationalize the QIs. Phase I includes identifying the cardiovascular focus or content area, determining the objective and/or purpose of the initiative, the target users of, and the target population for, the QIs, and selection of a QI working group. Phase II involves formulating the QIs including generating a preliminary set of QIs and draft definitions, followed by an indicator rating and ranking process based on the CCS QI rating criteria. Phase III involves finalizing technical specifications and pilot testing the QIs. It also describes the CCS QI approval process and addresses knowledge translation. Adoption of a standardized methodology for QI development will improve the quality, completeness, acceptability, and usability of pan-Canadian cardiovascular QIs developed by the CCS. Public release of the QI definitions and related performance data might help improve patient care quality and outcomes. Copyright © 2013 Canadian Cardiovascular Society. Published by Elsevier Inc.

    Full Text Available This study evaluated the effects of image pansharpening on Vegetation Indices (VIs, and found that pansharpening was able to downscale single-date and multi-temporal Landsat 8 VI data without introducing significant distortions in VI values. Four fast pansharpening methods—Fast Intensity-Hue-Saturation (FIHS, Brovey Transform (BT, Additive Wavelet Transform (AWT, and Smoothing Filter-based Intensity Modulation (SFIM—and two VIs—Normalized Difference Vegetation Index (NDVI and Simple Ratio (SR—were tested. The NDVI and SR formulas were both found to cause some spatial information loss in the pansharpened multispectral (MS bands, and this spatial information loss from VI transformations was not specific to Landsat 8 imagery (it will occur for any type of imagery. BT, SFIM, and other similar pansharpening methods that inject spatial information from the panchromatic (Pan band by multiplication, lose all of the injected spatial information after the VI calculations. FIHS, AWT, and other similar pansharpening methods that inject spatial information by addition, lose some spatial information from the Pan band after VI calculations as well. Nevertheless, for all of the single- and multi-date VI images, the FIHS and AWT pansharpened images were more similar to the higher resolution reference data than the unsharpened VI images were, indicating that pansharpening was effective in downscaling the VI data. FIHS best enhanced the spectral and spatial information of the single-date and multi-date VI images, followed by AWT, and neither significantly over- or under-estimated VI values.

    Rotationplasty is one treatment option for femoral bone sarcomas in skeletally immature patients. This procedure can also be used to save failed limb salvage procedures such as infected prostheses and failed bone grafts in adults. Rotationplasty is only rarely indicated, and the surgical complications and risk factors for failure of the procedure that might influence the treatment or patient choices have not been well described. We retrospectively reviewed 19 patients who underwent rotationplasty focusing on surgical indications, surgical procedures such as the type of rotationplasty, and whether vessels were sacrificed and reconstructed with vascular anastomosis or preserved. Risk factors for failure of rotationplasty were categorized into either early or late postoperative complications. Thirteen of 19 rotationplasties were done for patients diagnosed with primary sarcoma, 3 patients for unplanned excisions of sarcomas, and 3 patients for infection. Two of 19 patients did not have sufficient circulation resulting in amputation. Six of 19 patients underwent vascular anastomoses, and all of these anastomoses were successful. Three patients had multiple operations for infection before rotationplasty, and one patient's treatment failed so an amputation was required. As late complications, one patient had delayed bone union and one had postoperative infection that healed after removal of plate fixation. Two patients had malrotation of the tibia that resolved with revision surgery. One patient had a skin ulcer that healed with conservative treatment. One patient who had an unplanned excision had a hemipelvectomy for non-union 11 months after rotationplasty. Rotationplasty was successfully accomplished in 16 of the 19 patients (84 %) with sarcomas, unplanned excision of sarcomas or infection. Vascular anastomosis did not increase the risk of rotationplasty failure in our series. Patients appeared to have a higher risk of failure of rotationplasty after multiple

    Anthropogenic eutrophication is a major form of perturbation in freshwaters, and several approaches aim to recognise its effects on lake ecosystems. We compared the responses of diatom species morphology, diversity indices and diatom indices to total phosphorus, total nitrogen and distance from a point stressor causing eutrophication in a large lake. We specifically examined the degree to which extent nutrients and distance to the stressor affect variation in the values of various biological indices and diatom valve size. In addition, special attention was given to the adequate repetition of diatom valve width measurements in the context of environmental assessment. Our results showed that diatom valve width was a better indicator of nutrient concentrations than any of the diatom and diversity indices examined. However, the results varied between the two study transects, suggesting that the diatom-based variables not only respond to nutrients but also to other environmental factors (e.g. shoreline morphology). We also found that when using the method based on diatom morphology, one should measure more valves than has been originally suggested to provide a more reliable picture of response to eutrophication. We argue that diatom morphology could be considered as an additional environmental assessment tool, because it may complement the information provided by the traditional diatom indices. Diatom valve width may also be more sensitive to early phases of the eutrophication process and its effects on freshwater ecosystems than various diatom indices that were developed in regional contexts with wide ranges in nutrient levels.

  14. Indicators for Research Performance in the Humanities? The Scholars’ View on Research Quality and Indicators

    Energy Technology Data Exchange (ETDEWEB)

    Ochsner, M.; Hug, S.E.

    2016-07-01

    In this paper, we present indicators for research quality in the humanities collected in our previous work (Ochsner, Hug, & Daniel, 2012). We focus on how these indicators are accepted by humanities scholars. We also investigate differences between different subgroups of the humanities scholars we surveyed with regard to their preferences for such indicators. We address the theme of the conference (‘peripheries frontiers and beyond’) regarding two notions of (scientometric) periphery: First, we investigate indicators for research quality in the humanities, a field where there is a lack on knowledge on how to assess or even measure research quality, in fact, there is a quite broad consensus that (evaluative) bibliometrics cannot be readily applied in the humanities (Hicks, 2004; Nederhof, 2006). Second, we fully cover three humanities disciplines at Swiss universities and member universities of the League of European Research Universities (LERU). Scholars are a neglected stakeholder when it comes to the design of research assessment procedures or the selection of research indicators. However, they are directly affected, they know best what research quality in their field is and what impact the use of certain indicators could have on their research practices. The paper is structured as follows: first, we present the background for selecting indicators for research quality. This is followed by a description of our analysis methods and the presentation of the results. We finally discuss the results with regard to their use in research evaluation. (Author)

  15. Evaluation of Physiological Indices to Indicate Sleepy or Relaxed States Using Illuminance Stimulation

    The purpose of the present study was to clarify the ability of physiological indices to reflect the degree of sleepiness or relaxation of an individual due to stress, fatigue and other factors. Several studies have investigated the use of high-frequency (HF) components (0.15-0.40Hz) in heart rate variability to evaluate parasympathetic nervous activity. However, it has been difficult to assess the differences between states of sleepiness and relaxation using this method. In the present study, in order to evaluate the indices, two experimental illuminance conditions, 100 and 1,500 lx, reflecting differing states of arousal, were used during a cognitive judgment test lasting for 30 minutes. During the cognitive judgment test, electroencephalograms (EEG), electrocardiograms (ECG), physiological state and reaction time were measured, and results indicated that the two illuminance conditions could be differentiated from the recorded physiological data. More specifically, in the 1,500-lx condition, arousal level, activity level and test performance increased, and the level of HF components decreased. Opposite tendencies were observed in the 100-lx condition. Two indices of Lorenz plots (LP) at ECG RR intervals, center (C of LP) and ellipse area (S of LP), were subsequently determined from the physiological data. Subjects were then divided according to these LP indices based on their exhibited physiological responses, and we evaluated the effectiveness of the indices in differentiating between states of sleepiness and relaxation by comparing arousal level, psychological state, and reaction time. Results indicated that the C of LP and S of LP are possible indices for evaluating sleepiness or relaxation and suggest that these two indices may also be able to evaluate the relationship between physiological changes and other, subjective feelings.

  16. Rotifer trophic state indices as ecosystem indicators in brackish coastal waters

    2013-11-01

    Full Text Available Thanks to their short life cycles, rotifers react rapidly to changes in environmental conditions and so may be useful for biological monitoring. The objective of this paper was to investigate the applicability of rotifer trophic state indices as indicators of the trophic state of brackish waters, as exemplified by the Vistula Lagoon. Carried out in summer from 2007 to 2011, this study showed no significant correlation between the Lagoon's trophic state and the rotifer structure. This confirms the limited applicability of rotifer trophic state indices for evaluating water quality in brackish water bodies.

    Full Text Available Objectives: To investigate the indications and outcomes of amniotic membrane transplantation (AMT. Materials and Methods: A total of 87 eyes who underwent amnion membrane transplantation in our clinic between February 2010 and April 2013 were included in this study. Mean follow-up period was 7.49±7.84 months (range 1-29 months. Amnion membrane defrosted at room temperature and washed three times with saline covered all over the cornea independent of the position and size of the lesion and was sutured to the peripheral cornea circumferentially by 10/0 monofilament suture. At the end of the operation, therapeutic contact lens was placed. All cases were evaluated with respect to duration of surface epithelial healing, visual acuity, presence of recurrence, and infection. Results: Forty-six of the 87 patients (52.8% were men and 41 (47.1% were women. The mean age was 57.02±19.74 years (range 31-89 years in men and 66.69±16.56 years (range 8-88 years in women. The indications were: ulcers in 27 eyes, keratitis in 24 eyes, topical anesthetic abuse in 10 eyes, bullous keratopathy in 7 eyes, conjunctival mass in 7 eyes, symblepharon in 3 eyes, chemical burns in 3 eyes, pterygium in 2 eyes, endophthalmitis in 2 eyes, dellen in 1 eye, and conjunctival laceration in 1 eye. After AMT, 12 patients required second AMT, and 2 cases required third AMT. 2 eyes were eviscerated, 1 eye was exenterated. At the final follow-up visit, except for patients who underwent evisceration and exenteration, improved visual acuity was observed in 45 of the 84 eyes (53.5%. The average of healing time was between 4 and 6 weeks. No infectious, inflammatory, immunologic, or toxic/allergic reactions related to AMT was observed. Conclusion: Amniotic membrane transplantation is a safe and effective technique in ocular surface diseases. (Turk J Ophthalmol 2014; 44: 123-6

    ‘Ecosystem recovery’ is a concept that emerged from the need to preserve our environment against increasing contamination from human activity. However, ecological indicators of ecosystem recovery remain scarce, and it is still difficult to assess recovery of ecological processes at relevant spatial and temporal scales. Microbial communities hold key relevance as indicators of ecosystem recovery as they are ubiquitous among diverse ecosystems, respond rapidly to environmental changes, and supp...

    It is widely believed that oppressive dreams are frequent in bereavement--despite the lack of scientific investigations of the subject. The aims of our study were the analysis of dream quality as well as the correlates of oppressive dreams in bereavement. Participants with (N = 473) and without bereavement were compared upon the database of a national representative study (Hungarostudy Epidemiological Panel Survey 2006, N = 4329). Dream contents were assessed with the Dream Quality Questionnaire (DQQ). Depressive symptoms (BDI-S) and the presence anxiety were also investigated. Oppressive dreams occurred significantly higher frequency in the first year of bereavement (men: F = 17.525, p dreams were significantly associated with anxiety (F = 37.089, p dreams are significantly more frequent in the first year of bereavement, and may act as indicators of bereavement-linked mental health consequences like depression and anxiety. These are often masked by the symptoms of grief and therefore remain untreated. Our preliminary results could be a starting point for the development of further research aiming to clarify the relationship amongst dream contents, anxiety, and depression in bereavement.

    For the generation of sound, some woodwind musical instruments, e.g. oboe, bassoon, clarinet and saxophone, are provided with mouthpieces made from reeds. These reeds are the culms of Arundo donax, a tall, cane-like perennial grass. A general problem is that the material is of varying quality, yet externally differences cannot be observed. Hence, large proportions of the prepared reeds are unusable. One hypothesis is that the changes in quality are correlated with differences in the chemical and anatomical structure of the tissue. Therefore, a comparison of superior and inferior mouthpieces, used by professional musicians, was undertaken to determinate potential indicators of quality. Nuclear microprobe analysis of reeds was carried out and complemented by scanning electron and light microscopy. The elemental levels of Si, P, S, Cl, K and Ca were compared between good and poor mouthpieces using appropriate statistical tests. No statistically significant differences could be identified. Microscopical observations showed that partial occlusion of vessels by tylose formation was associated with material deemed unusable.

  1. PERFORMANCE MEASUREMENT THROUGH NON-FINANCIAL INDICATORS

    Full Text Available The information about a company’s performance is necessary in order to evaluate the potential modifications of the economic resources that the entity will be able to control in the future, to anticipate the ability to generate treasury fluxes with the available resources, and to establish the efficiency with which it can employ and make use of new resources. In current practice, the information regarding financial performance are mainly given by “the profit and loss account”, respectively “the budgetary execution account”, but things are not so simple as to reduce them to the synthetic data in a certain periodic report form since it would be a pity to ignore the real - time information given by the account itself. In our paper we have tried to resume the most important non-financial indicators, through which the performance of a company is measured.

  2. Amputation: A Rare Surgical Indication in Melorheostosis

    Full Text Available Melorheostosis is a rare and progressive mesenchymal dysplasia characterized by thickening (hyperostosis of the cortical bone. It is a developmental error that has been described to occur due to a mutation in LEMD3 gene. It affects bone and soft tissue development resulting in severe functional limitation; chronic pain, malformed or immobilized muscles, tendons or ligaments limb deformities and leg length discrepancies. X-ray imaging is the preferred diagnostic tool for melorheostosis, which often reveals a pattern of thickened bone resembling dripping candle wax. Treatment of melorheostosis is limited and generally conservative that includes physical and occupational therapy, and in severe cases, surgery may be considered. We report a case of 68-year-old female with melorheostosis of the middle finger, with her chief complaint being gross swelling, complete restriction of movement of all joints of the middle finger and limitations in movements of joints of index and ring finger, making the hand almost non-functional. It was treated with amputation, a rare surgical indication.

    The extension of subduction processes into the Eoarchaean era (4.0-3.6 Ga) is controversial. The oldest reported terrestrial olivine, from two dunite lenses within the ∼3,720 Ma Isua supracrustal belt in Greenland, record a shape-preferred orientation of olivine crystals defining a weak foliation and a well-defined lattice-preferred orientation (LPO). [001] parallel to the maximum finite elongation direction and (010) perpendicular to the foliation plane define a B-type LPO. In the modern Earth such fabrics are associated with deformation of mantle rocks in the hanging wall of subduction systems; an interpretation supported by experiments. Here we show that the presence of B-type fabrics in the studied Isua dunites is consistent with a mantle origin and a supra-subduction mantle wedge setting, the latter supported by compositional data from nearby mafic rocks. Our results provide independent microstructural data consistent with the operation of Eoarchaean subduction and indicate that microstructural analyses of ancient ultramafic rocks provide a valuable record of Archaean geodynamics.

    2014-07-01

    To describe trends in corneal transplantation surgery, including indications for surgery, evolution of lamellar keratoplasty, current surgical techniques, and future directions. Over the past decade, anterior and posterior lamellar keratoplasty have begun to supplant penetrating keratoplasty. Surgical techniques continue to change and improve outcomes. In recent years, Descemet membrane endothelial keratoplasty (DMEK) has gained interest as it eliminates the corneal stromal interface, which may limit visual acuity after Descemet stripping automated endothelial keratoplasty. Despite the promising results with improved visual acuity and decreased rejection, the technical challenges associated with DMEK have limited widespread acceptance. With technical refinements and more eye banks providing precut tissue for both Descemet stripping automated endothelial keratoplasty and DMEK, it is likely both procedures will continue to increase over time. Corneal transplantation has evolved rapidly over the past decade, from full-thickness penetrating keratoplasty towards lamellar keratoplasty to only remove and replace damaged layers of the cornea. Achieving minimal induced astigmatism with excellent visual acuity remains a challenge in corneal transplantation. Further refinements in surgical technique may help improve technical challenges and visual outcomes. In this article, we review changing trends in corneal transplantation and highlight developing medical treatments that may be available in the future.

    2014-11-10

    Multiple indicators, multiple causes (MIMIC) models are often employed by researchers studying the effects of an unobservable latent variable on a set of outcomes, when causes of the latent variable are observed. There are times, however, when the causes of the latent variable are not observed because measurements of the causal variable are contaminated by measurement error. The objectives of this paper are as follows: (i) to develop a novel model by extending the classical linear MIMIC model to allow both Berkson and classical measurement errors, defining the MIMIC measurement error (MIMIC ME) model; (ii) to develop likelihood-based estimation methods for the MIMIC ME model; and (iii) to apply the newly defined MIMIC ME model to atomic bomb survivor data to study the impact of dyslipidemia and radiation dose on the physical manifestations of dyslipidemia. As a by-product of our work, we also obtain a data-driven estimate of the variance of the classical measurement error associated with an estimate of the amount of radiation dose received by atomic bomb survivors at the time of their exposure.

  7. Compressing bitmap indices by data reorganization

    2004-07-01

    Many scientific applications generate massive volumes of data through observations or computer simulations, bringing up the need for effective indexing methods for efficient storage and retrieval of scientific data. Unlike conventional databases, scientific data is mostly read-only and its volume can reach to the order of petabytes, making a compact index structure vital. Bit map indexing has been successfully applied to scientific databases by exploiting the fact that scientific data are enumerated or numerical. Bitmap indices can be compressed with variants of run length encoding for a compact index structure. However even this may not be enough for the enormous data generated in some applications such as high energy physics. In this paper, we study how to reorganize bitmap tables for improved compression rates. Our algorithms are used just as a preprocessing step, thus there is no need to revise the current indexing techniques and the query processing algorithms. We introduce the tuple reordering problem, which aims to reorganize database tuples for optimal compression rates. We propose Gray code ordering algorithm for this NP-Complete problem, which is an in-place algorithm, and runs in linear time in the order of the size of the database. We also discuss how the tuple reordering problem can be reduced to the traveling salesperson problem. Our experimental results on real data sets show that the compression ratio can be improved by a factor of 4 to 7.

    Bariatric surgery is known to be the most effective and long lasting treatment for morbid obesity and many related conditions, but now mounting evidence suggests it may be among the most effective forms of treatment for metabolic diseases and conditions including type 2 diabetes, hypertension, high cholesterol levels, non-alcoholic fatty liver disease and obstructive sleep apnea. Surgery for severe obesity goes way beyond weight loss. This surgery results in the complete remission or significant improvement of type 2 diabetes and other life-threatening diseases in most patients. The new name metabolic surgery was created and reflects this expanded and evolving view of surgery. Therefore, metabolic surgery is expected to play an ever increasing role in managing these diseases. New research results indicate that metabolic surgery may improve insulin resistance and secretion by mechanisms independent of weight loss, most likely involving changes in gastrointestinal hormones. Many patients with type 2 diabetes experience complete remission within days of metabolic surgery, long before significant weight is lost. This has led to a new concept that metabolic surgery may also be appropriate for diabetic individuals who are of normal weight or only slightly overweight.

    An important aspect of constructed wetlands design for landfill leachate treatment is the assessment of landfill leachate phytotoxicity. Intravital methods of plants response observation are required both for lab scale toxicity testing and field examination of plants state. The study examined the toxic influence of two types of landfill leachate from landfill in Zakurzewo (L1) and landfill in Wola Pawłowska (L2) on five plant species: reed Phragmites australis (Cav.) Trin. ex Steud, manna grass Glyceria maxima (Hartm.) Holmb., bulrush Schoenoplectus lacustris (L.) Palla, sweet flag Acorus calamus L., and miscanthus Miscanthus floridulus (Labill) Warb. Transpiration measurement was used as indicator of plants response. The lowest effective concentration causing the toxic effect (LOEC) for each leachate type and plant species was estimated. Plants with the highest resistance to toxic factors found in landfill leachate were: sweet flag, bulrush, and reed. The LOEC values for these plants were, respectively, 17%, 16%, 9% in case of leachate L1 and 21%, 18%, 14% in case of L2. Leachate L1 was more toxic than L2 due to a higher pH value under similar ammonia nitrogen content, i.e. pH 8.74 vs. pH 8.00. Copyright © 2015 Elsevier Ltd. All rights reserved.

    In patients with the malignant tumor of bone (17 osteosarcomas, 8 Ewing tumors) longterm observations were made, and namely at the beginning of the disease, after the surgical removal of the tumor, during chemotherapy and in the terminal phase of the disease. The observations concentrated on the following selected immunology parameters: active lymphocytes T, lymphocytes T, lymphocytes B, large granular lymphocytes, IgG, IgA, IgM and circulating immune complexes. In non-treated patients prior to diagnosing the disease, reduction of active lymphocytes T was found out while the total lymphocytes T remained unchanged. However, no significant differences were found out between benign and malignant tumors. The surgical removal of the tumor results in the change in imunologic indicators, the increase of active lyphocytes T, lymphocytes T and the decrease in the circulating immune complexes. The change is of temporary nature, the subsequent deterioration is caused by both the progression of the disease and chemotherapy. The values of immunoglobulins and lymphocytes B fluctuated during the whole course of the disease in physiological levels. The observation of active lymphocytes T and lymphocytes T can be used for monitoring of the immunosuppression in cytostatic treatment. The levl of IgG is differentially diagnostically used to distinguish between the tumor and inflammatory processes.

  12. Lenticels as indicators of atmospheric smoke pollution

    Energy Technology Data Exchange (ETDEWEB)

    Pesek, F.

    1960-01-01

    The invasion of smoke pollution gets from the atmosphere into the plants only by lenticels and stomata. The most toxic smoke constituents penetrating into the stele are SO/sub 2/, H/sub 2/SiF/sub 6/, H/sub 3/AsO/sub 4/, HCl and C/sub 6/H/sub 5/OH. Lenticels are bark stomata filled with merenchym tissue, which hinders the entrance of mechanical smoke particles into the interior tissues of the stele. In autumn, the lenticels are packed by cork slabs formed by the cork cambium. In spring, this cork slab is broken by a new mechanical tissue. Sambucus nigra L. has a merenchym sensitive to the presence of smoke pollution, and the lenticels may serve, therefore, as indicators of smoke pollution in the atmosphere. The intensity of damage caused by smoke constituents penetrating into the plants through lenticels depends upon a series of exterior and interior factors. They are the number of lenticels per area unit of bark surface in the whole circumference, the pH of the biocomplex near the lenticel in the interior tissues of stele, and the concentration of smoke pollution in the atmosphere. The most effective way of preventing smoke damage is to install pollution control equipment in the industrial works.

    2014-01-01

    Quality indicators (QIs) measure the extent to which set targets are attained and provide a quantitative basis for achieving improvement in care and, in particular, laboratory services. A body of evidence collected in recent years has demonstrated that most errors fall outside the analytical phase, while the pre- and post-analytical steps have been found to be more vulnerable to the risk of error. However, the current lack of attention to extra-laboratory factors and related QIs prevent clinical laboratories from effectively improving total quality and reducing errors. Errors in the pre-analytical phase, which account for 50% to 75% of all laboratory errors, have long been included in the ‘identification and sample problems’ category. However, according to the International Standard for medical laboratory accreditation and a patient-centered view, some additional QIs are needed. In particular, there is a need to measure the appropriateness of all test request and request forms, as well as the quality of sample transportation. The QIs model developed by a working group of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) is a valuable starting point for promoting the harmonization of available QIs, but further efforts should be made to achieve a consensus on the road map for harmonization.

    Traditional antipersonnel land mines are an effective military tool, but they are unable to distinguish friend from foe, or civilian from military personnel. The concept described here uses an advanced moving target indicator (MTI) radar to scan the minefield in order to detect movement towards or within the minefield, coupled with visual identification by a human operator and a communication link for command and control. Selected mines in the minefield can then be activated by means of the command link. In order to demonstrate this concept, a 3D, interactive simulation has been developed. This simulation builds on previous work by integrating a detailed analytical model of an MTI radar. This model has been tailored to the specific application of detection of slowly moving dismounted entities immersed in ground clutter. The model incorporates the effects of internal scatterer motion and antenna scanning modulation in order to provide a realistic representation of the detection problem in this environment. The angle information on the MTI target detection is then passed to a virtual 3D sight which cues a human operator to the target location. In addition, radar propagation effects and an experimental design in which the radar itself is used as a command link are explored.

    A poly(vinyl alcohol) (PVA) film containing acid-sensitive dye (bromophenol red, BPR) and water soluble chlorine-containing substance [CCl 3COONa or chloral hydrate (CCl 3CH(OH) 2, 2,2,2-trichloroethan-1,1-diol)] may be useful as a radiation-sensitive indicator. The acid-sensitive dye in the film changes its color from violet to pale yellow by irradiation due to the consequent lowering of the pH of the film caused by the HCl generated from the radiolysis of the Cl-containing substance. This film can be used as a dosimeter in a relatively low dose range up to 5 kGy. This response range makes this film useful in some food irradiation, pasteurization and water purification applications. The effects of temperature and relative humidity during irradiation and post-irradiation storage on the response of the film are discussed. It is inexpensive, does not require toxic solvents in preparation and easy to prepare in a laboratory.

  16. [Major depression: features indicative of bipolarity?].

    Azorin, J-M

    2011-12-01

    Several recent studies have shown that bipolar disorder is underdiagnosed in patients with major depression. Missing the diagnosis of a bipolar disorder may have serious and even occasionally fatal consequences for a patient with the disease. Moreover misdiagnosis may lead to inappropriate treatment and therefore contribute to worsening medical and functional prognosis. Although there are no pathognomonic characteristics of bipolar depression compared to unipolar depression, evidence-based findings suggest that some features may be indicative of bipolarity, in patients with depression. These features are related to clinical picture of depressive state, course of episode and illness, response to treatment, family history, comorbid conditions, as well as demographic and temperamental characteristics. Based on such features, some authors have proposed operationalized criteria or a diagnostic specific for bipolarity, to identify bipolar depression. Screening instruments may also be used, to facilitate early recognition. Validation studies of these diagnostic features and instruments are underway. Copyright © 2011 L’Encéphale.

Maintaining approximately equal levels of concreteness EGE and FCE texts obtain about the same levels of complexity (B2 due to the differences in the number of verbalized local and global content links. Thus, the Russian test developers model the authentic English texts for examination purposes eliminating the connectives and verbalizing referential and deep cohesion.

  18. Mechanistic Indicators of Childhood Asthma (MICA): piloting ...

    Science.gov (United States)

    Background: Modem methods in molecular biology and advanced computational tools show promise in elucidating complex interactions that occur between genes and environmental factors in diseases such as asthma; however appropriately designed studies are critical for these methods to reach their full potential. Objective: We used a case-control study to investigate whether genomic data (blood gene expression), viewed together with a spectrum of exposure effects and susceptibility markers (blood, urine and nail), can provide a mechanistic explanation for the increased susceptibility of asthmatics to ambient air pollutants. Methods: We studied 205 non-asthmatic and asthmatic children, (9-12 years of age) who participated in a clinical study in Detroit, Michigan. The study combines a traditional epidemiological design with an integrative approach to investigate the environmental exposure of children to indoor-outdoor air. The study includes measurements of internal dose (metals, allergen specific IgE, PAH and VOC metabolites) and clinical measures of health outcome (immunological, cardiovascular and respiratory). Results: Expected immunological indications of asthma have been obtained. In addition, initial results from our analyses point to the complex nature of childhood health and risk factors linked to metabolic syndrome (obesity, blood pressure and dyslipidemia). For example, 31% and 34% of the asthmatic MICA subjects were either overweight (BMI > 25) o

    The purpose of this study is, first to present a 10-year monitoring of postanalytical turnaround time (TAT) adapted to different clinicians and patient situations, second to evaluate and analyse the indicators results during that period of time, and finally to show a synthetic appropriate indicator to be included in the balanced scorecard management system. TAT indicator for routine samples was devised as the percentage of certain key tests that were verified before a specific time on the phlebotomy day. A weighted mean synthetic indicator was also designed. They were calculated for inpatients at 15:00 and 12:00 and for primary care patients only at 15:00. The troponin TAT of emergency department patients, calculated as the difference between the troponin verification and registration time, was selected as the stat laboratory TAT indicator. The routine and stat TAT improved along the 10-year study period. The synthetic indicator showed the same trend. The implementation of systematic and continuous monitoring over years, promoted a continuous improvement in TAT which will probably benefit patient outcome and safety.

    This study aims to establish a common Key Performance Indicators (KPIs) framework for reporting about the gypsum industry biodiversity at the European level. In order to integrate different opinions and to reach a consensus framework, an original participatory process approach has been developed among different stakeholder groups: Eurogypsum, European and regional authorities, university scientists, consulting offices, European and regional associations for the conservation of nature, and the extractive industry. The strategy is developed around four main steps: (1) building of a maximum set of indicators to be submitted to stakeholders based on the literature (Focus Group method); (2) evaluating the consensus about indicators through a policy Delphi survey aiming at the prioritization of indicator classes using the Analytic Hierarchy Process method (AHP) and of individual indicators; (3) testing acceptability and feasibility through analysis of Environmental Impact Assessments (EIAs) and visits to three European quarries; (4) Eurogypsum final decision and communication. The resulting framework contains a set of 11 indicators considered the most suitable for all the stakeholders. Our KPIs respond to European legislation and strategies for biodiversity. The framework aims at improving sustainability in quarries and at helping to manage biodiversity as well as to allow the creation of coherent reporting systems. The final goal is to allow for the definition of the actual biodiversity status of gypsum quarries and allow for enhancing it. The framework is adaptable to the local context of each gypsum quarry.

    Full Text Available Conventional echocardiographic (ECHO parameters of systolic and diastolic func-tion of the left ventricular (LV have been shown to be load dependent. However, the impact of pre-load reduction on tissue Doppler (TD parameters of LV function is incompletely understood. To evaluate the effect of a single hemodialysis (HD session on LV systolic and diastolic function using pulsed Doppler echocardiography and pulsed tissue Doppler imaging (TDI, we studied 81chronic HD patients (40 males; mean age 52.4 ± 16.4 years with these tools. ECHO parameters were obtained 30 min before and 30 min after HD. Fluid volume removed by HD was 1640 ± 730 cm [3] . HD led to reduction in LV end-diastolic volume (P <0.001, end-systolic volume (P <0.001, left atrium area (P <0.001, peak early (E-wave trans-mitral flow velocity (P <0.001, the ratio of early to late Doppler velocities of diastolic mitral inflow (P <0.001 and aortic time velocity integral (P <0.001. No significant change in peak S velocity of pulmonary vein flow after HD was noted. Early and late diastolic (E′ TDI velocities and the ratio of early to late TDI diastolic velocities (E′/A′ on the lateral side of the mitral annulus decreased signi-ficantly after HD (P = 0.013; P = 0.007 and P = 0.008, respectively. Velocity of flow progres-sion (Vp during diastole was not affected by pre-load reduction. Pulmonary artery systolic pressure and the diameter of the inferior vena cava decreased significantly (P <0.001 and P <0.001, respectively after HD. We conclude that most of the Doppler-derived indices of diastolic function are pre-load-dependent and velocity of flow progression was minimally affected by pre-load reduction in HD patients.

  2. Tamper-indicating quantum optical seals

    Humble, Travis S [ORNL; Williams, Brian P [ORNL

    2015-01-01

    Confidence in the means for identifying when tampering occurs is critical for containment and surveillance technologies. Fiber-optic seals have proven especially useful for actively surveying large areas or inventories due to the extended transmission range and flexible layout of fiber. However, it is reasonable to suspect that an intruder could tamper with a fiber-optic sensor by accurately replicating the light transmitted through the fiber. In this contribution, we demonstrate a novel approach to using fiber-optic seals for safeguarding large-scale inventories with increased confidence in the state of the seal. Our approach is based on the use of quantum mechanical phenomena to offer unprecedented surety in the authentication of the seal state. In particular, we show how quantum entangled photons can be used to monitor the integrity of a fiber-optic cable - the entangled photons serve as active sensing elements whose non-local correlations indicate normal seal operation. Moreover, we prove using the quantum no-cloning theorem that attacks against the quantum seal necessarily disturb its state and that these disturbances are immediately detected. Our quantum approach to seal authentication is based on physical principles alone and does not require the use of secret or proprietary information to ensure proper operation. We demonstrate an implementation of the quantum seal using a pair of entangled photons and we summarize our experimental results including the probability of detecting intrusions and the overall stability of the system design. We conclude by discussing the use of both free-space and fiber-based quantum seals for surveying large areas and inventories.

    CNAO will be a dual center capable of providing therapeutic beams of protons and carbon ions with maximum energy of 400 MeV/u. At the beginning, it will be equipped with three treatment rooms with fixed horizontal and vertical beam lines. In a subsequent phase, two more rooms with a rotating gantry are foreseen. An active spot scanning dose delivery system will be employed. Initially, 80% of the treatments will be carried out with carbon ions. All patients will be treated within clinical trials to assess carbon ion indications with an evidence-based methodology. Seven disease-specific working groups have been developed: lung tumors, liver tumors, sarcomas, head and neck tumors, central nervous system lesions, eye tumors and pediatric tumors. The last two groups will be treated mainly with protons. In the first phase, CNAO will focus on head and neck cancers, treating inoperable, residual or recurrent malignant salivary gland tumors, mucosal melanoma, adenocarcinoma and unfavorably located SCC (nasal and paranasal sinuses). Carbon ions will be employed as a boost in the treatment of locally advanced, poor prognosis, SCC of the hypopharynx and tongue base. Bone and soft tissue sarcomas of the extremity will be treated with a limb-sparing approach, and trunk sarcomas will be treated with exclusive or post-operative irradiation. Skull base tumors (chordoma and chondrosarcoma), recurrent or malignant meningioma and glial tumors will be treated with carbon ions. After sufficient expertise has been gained in coping with organ motion, CNAO will start treating thoracic and abdominal targets. HCC will be treated in inoperable patients with one or more lesions that can be included in a single CTV. Early stage NSCLC will be treated. In the second phase, two more groups on gynecological malignancies and digestive tumors (esophageal cancer, rectal cancer, pancreatic cancer) will be created.

    The introduction on spiral computed tomography (spiral CT) has vastly enriched the methodological diversity of computer-tomographic scans. It allows for the recording of different perfusion or excretion stages of the kidney parenchyma of the urine draining paths by carrying out long-distance, phase-identical multiple examinations of the retroperitoneum. The description of the findings which are characterized by their local and contrasts behavior is possible. The following report describes the indications and technological process of kidney spiral CT using kidney-typical intravenous contrast media. Special emphasis is put on the advantages and limits of multiple phase spiral CT. Decisive preconditions are: 1. specific clinical query, 2. selection of the corresponding phase contrasts of the kidneys and uretra or bladder, 3. exact technical and temporal adjustment of the acquisition parameters. Scanning times are in the range of seconds. The overall examination can be carried out quick and without any major strain on the part of the patient. A sound proof and a general differentiation of focal kidney lesions can be derived from the acquired data. This is also true for kidneys and ureters findings. Bladder findings can be localized and differentiated according to stage. More than two "spiral acquisitions" should be carried out with re-straint taking exposure to radiation into account. Due to the sound registration of focal lesions, its capability of reproduction and its short-time examination, the spiral CT of the kidneys can be said to be the most effective current scanning method of the retroperitoneum following clinical examinations and sonography.

    Bottlenose dolphins can have iron overload (that is, hemochromatosis), and managed populations of dolphins may be more susceptible to this disease than are wild dolphins. Serum iron, total iron-binding capacity (TIBC), transferrin saturation, and ferritin were measured in 181 samples from 141 dolphins in 2 managed collections and 2 free-ranging populations. Although no iron indices increased with age among free-ranging dolphins, ferritin increased with age in managed collections. Dolphins from managed collections had higher iron, ferritin, and transferrin saturation values than did free-ranging dolphins. Dolphins with high serum iron (exceeding 300 μg/dL) were more likely to have elevated ferritin but not ceruloplasmin or haptoglobin, demonstrating that high serum levels of iron are due to a true increase in total body iron. A time-series study of 4 dolphins with hemochromatosis that were treated with phlebotomy demonstrated significant decreases in serum ferritin, iron, and TIBC between pre- and posttreatment samples; transferrin saturation initially fell but returned to prephlebotomy levels by 6 mo after treatment. Compared with those in managed collections, wild dolphins were 15 times more likely to have low serum iron (100 μg/dL or less), and this measure was associated with lower haptoglobin. In conclusion, bottlenose dolphins in managed collections are more likely to have greater iron stores than are free-ranging dolphins. Determining why this situation occurs among some dolphin populations and not others may improve the treatment of hemochromatosis in dolphins and provide clues to causes of nonhereditary hemochromatosis in humans.

The goal of this manuscript is to review the biomechanical relevance of the human knee's menisci in relation to surgical indications, surgical techniques, rehabilitation, and outcomes. In order to identify the relevant literature, we performed a PubMed search for the years ranging from 1980–2013 using the following search terms: meniscus; biomechanical function; meniscectomy; meniscal repair; and clinical outcome. The meniscus helps to distribute the forces between the tibial and femoral articular cartilage layers in a load-sharing capacity. Meniscus damage or meniscectomy intuitively leads to an overloading of the cartilage and, hence, to the development of osteoarthrosis. Precise knowledge of meniscal shape and function, of the type of injury, of surgical techniques, as well as of postsurgical rehabilitative care are of decisive importance for an individually-adjusted treatment strategy. Other underlying coexisting knee pathologies also need to be considered. The diagnosis of a meniscal injury is based upon clinical history, physical examination, and imaging studies. The treatment of a meniscal lesion includes conservative, as well as operative, procedures. The goals of surgery are to reduce pain and disability, as well as to preserve meniscal function without causing additional cartilage damage. The resection of meniscal tissue should be restricted to as much as is necessary, and as little as is reasonably possible. Postoperative rehabilitation serves the purpose of improving functional deficits and pain, as well as of restoring a good range of

    There is no general agreement on the best indication and timing of vitrectomy in patients suffering from Terson syndrome. Therefore, we reviewed our cases in order to assess factors interfering with the functional outcome and complication rates after vitrectomy. In this retrospective consecutive case series, the records from all patients undergoing vitrectomy for Terson syndrome between 1975 and 2005 were evaluated. Thirty-seven patients (45 eyes) were identified, 36 of whom (44 corresponding eyes) were eligible. The best-corrected visual acuity (BCVA) at first and last presentation was 0.07 +/- 0.12 and 0.72 +/- 0.31, respectively. Thirty-five eyes (79.5%) achieved a postoperative BCVA of > or = 0.5; 26 (59.1%) eyes achieved a postoperative BCVA of > or = 0.8. Patients operated on within 90 days of vitreous haemorrhage achieved a better final BCVA than those with a longer latency (BCVA of 0.87 +/- 0.27 compared to 0.66 +/- 0.31; P = 0.03). Patients younger than 45 years of age achieved a better final BCVA than older patients (0.85 +/- 0.24 compared to 0.60 +/- 0.33; P = 0.006). Retinal detachment developed in four patients between 6 and 27 months after surgery. Seven patients (16%) required epiretinal membrane peeling and seven cataract surgery. Ninety-eight per cent of our patients experienced a rapid and persisting visual recovery after removal of a vitreous haemorrhage caused by Terson syndrome. A shorter time between occurrence of vitreous haemorrhage and surgery as well as a younger patient age are predictive of a better outcome. Generally, the surgical risk is low, but complications (namely retinal detachment) may occur late after surgery.

    This study compares complementary feeding World Health Organization (WHO) indicators with those built in accordance with Brazilian recommendations (Ten Steps to Healthy Feeding). A cross-sectional study was carried out during the National Immunization Campaign against Poliomyelitis in Guarapuava-Paraná, Brazil, in 2012. Feeding data from 1,355 children aged 6-23 months were obtained through the 24 h diet recall. Based on five indicators, the proportion of adequacy was evaluated: introduction of solid, semi-solid, or soft foods; minimum dietary diversity; meal frequency; acceptable diet; and consumption of iron-rich foods. Complementary feeding showed adequacy higher than 85% in most WHO indicators, while review by the Ten Steps assessment method showed a less favorable circumstance and a high intake of unhealthy foods. WHO indicators may not reflect the complementary feeding conditions of children in countries with low malnutrition rates and an increased prevalence of overweight/obesity. The use of indicators according to the Ten Steps can be useful to identify problems and redirect actions aimed at promoting complementary feeding. © 2016 John Wiley & Sons Australia, Ltd.

    2007-01-01

    The European Water Framework Directive will have instituted the concept of Ecological Quality Status (EQS) as a way to assess the biological quality of water masses. The EQS will be based mainly upon the composition of the different biological compartments in the ecosystem specially the benthos as compared to certain reference sites. Such management tools are already well established for freshwater (i.e. biotic indices), but not for coastal and estuarine (i.e. transitional) waters. In the framework of the Seine-Aval programme a workshop on benthic indicators was organized at Wimereux (France) in June 2005. The aim of this workshop and this paper is (1) to present the experiences of the Seine Aval researchers, and the French scientific approaches to benthic indicators, with those international experiences and approaches that have been published or are under development; and (2) to examine the existing benthic tools and their possible use in the characterization of the state of estuarine ecosystems. The debate during the workshop and the numerous recently published on the WFD are discussed in term of the implementation of the WFD in transitional water bodies using benthic indicators and indices. Some proposals for the future underline the needs to re-examine and adapt the different index thresholds, to take into account physical disturbances, to inventory the existing conditions vs reference conditions and to be as pragmatic as possible in using the WFD in transitional waters.

    The general goal of the project wherein this paper is framed is the proposal of useful quality and safety procedures and indicators to facilitate quality improvement in digestive endoscopy units. This initial offspring sets forth procedures and indicators common to all digestive endoscopy procedures. First, a diagram of pre- and post-digestive endoscopy steps was developed. A group of health care quality and/or endoscopy experts under the auspices of the Sociedad Española de Patología Digestiva (Spanish Society of Digestive Diseases) carried out a qualitative review of the literature regarding the search for quality indicators in endoscopic procedures. Then, a paired analysis was used for the selection of literature references and their subsequent review. Twenty indicators were identified, including seven for structure, eleven for process (five pre-procedure, three intra-procedure, three post-procedure), and two for outcome. Quality of evidence was analyzed for each indicator using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification.

Upper airway obstruction and feeding difficulties are the main concerns related to the pathology. Mandibular distraction should be considered a treatment option (when other treatments result inadequate. Patiants and methods Ten patients between the ages of 1 month and 2 years with severe micrognathia and airway obstruction were treated with Mandibular Distraction Osteogenesis (MDO. All patients underwent fibroscopic examination of the upper airway and a radiographic imaging and/or computed tomography scans to detect malformations and to confirm that the obstruction was caused by posterior tongue displacement. All patients were evaluated by a multidisciplinary team. Indications for surgery included frequent apneic episodes with severe desaturation (70%. Gavage therapy was employed in all patients since oral feeding was not possible. The two tracheotomy patients were 5 months and 2 years old respectively, and the distraction procedure was performed to remove the tracheotomy tube. All patients were treated with bilateral mandibular distraction: two cases with an external multivector distraction device, six cases with an internal non-resorbable device and two cases with an internal resorbable device. In one case, the patient with Goldenhar's Syndrome, the procedure was repeated. Results The resolution of symptoms was obtained in all patients, and, when present, tracheotomy was removed without complications. Of the two patients with pre-existing tracheotomies, in the younger patient (5 months old the tracheotomy was removed 7 days postoperatively. In the Goldenhar's syndrome case (2 years old a Montgomery device was necessary for 6 months due to the presence of tracheotomy-inducted tracheomalacia. Patients were discharged when the

    For many years now percutaneous techniques have proved effective in the curative treatment of lumbar disc herniation, mostly in young subjects. This technique, however, is seldom indicated, let alone performed, in the cervical spine for a variety of reasons: a) the neck contains several closely arranged structures such as the vasculo-nervous bundles, the airway-digestive tract and the cervical spine around the spinal cord; b) the disc is approached by the anterior route, in contrast with the lumbo-sacral spine where the approach is posterolateral; c) the manufacturers insist on restrictions in the use of chymopapain in view of the potential risk of spinal cord damage, either by possible breaks in the meninges of by accidental diffusion of the enzyme into perimedullary epidural structures which support a particularly developed venous plexus; d) legal protection may be denied to operators who perform cervical chemonucleolysis, since the product has not yet been officially authorized, in France and perhaps elsewhere*, for treatment of cervical disc herniation. Several years of experience in the practice of cervical nucleolysis have convinced the authors that this method is remarkably effective and can be used in the treatment of cervicobrachial neuralgia (CBN) occurring in young subjects. Radiculalgia is essentially due to a disc fragment being positioned within the vertebral canal or a foramen, thereby compressing the nerve roots. During several years microsurgery of the disc has been effective in the treatment of refractory radiculalgia, and to compete with this procedure familiar to neurosurgeons cervical nucleolysis must convincingly demonstrate that its therapeutic value is at least as good as that of surgery. Finally, the vast majority of cervical disc herniations is made up of free disc fragments located within the meshes of the posterior longitudinal ligament of the spine (transligamentous fragment). Cervical nucleolysis was introduced in France by Bonafe and

  13. Image Quality Indicator for Infrared Inspections

    2011-01-01

    The quality of images generated during an infrared thermal inspection depends on many system variables, settings, and parameters to include the focal length setting of the IR camera lens. If any relevant parameter is incorrect or sub-optimal, the resulting IR images will usually exhibit inherent unsharpness and lack of resolution. Traditional reference standards and image quality indicators (IQIs) are made of representative hardware samples and contain representative flaws of concern. These standards are used to verify that representative flaws can be detected with the current IR system settings. However, these traditional standards do not enable the operator to quantify the quality limitations of the resulting images, i.e. determine the inherent maximum image sensitivity and image resolution. As a result, the operator does not have the ability to optimize the IR inspection system prior to data acquisition. The innovative IQI described here eliminates this limitation and enables the operator to objectively quantify and optimize the relevant variables of the IR inspection system, resulting in enhanced image quality with consistency and repeatability in the inspection application. The IR IQI consists of various copper foil features of known sizes that are printed on a dielectric non-conductive board. The significant difference in thermal conductivity between the two materials ensures that each appears with a distinct grayscale or brightness in the resulting IR image. Therefore, the IR image of the IQI exhibits high contrast between the copper features and the underlying dielectric board, which is required to detect the edges of the various copper features. The copper features consist of individual elements of various shapes and sizes, or of element-pairs of known shapes and sizes and with known spacing between the elements creating the pair. For example, filled copper circles with various diameters can be used as individual elements to quantify the image sensitivity

    Astronomers studying archival data from an Australian radio telescope have discovered a powerful, short-lived burst of radio waves that they say indicates an entirely new type of astronomical phenomenon.

The research team led by Lorimer consists of Matthew Bailes of Swinburne University in Australia, Maura McLaughlin of WVU and NRAO, David Narkevic of WVU, and Fronefield Crawford of Franklin and Marshall College in Lancaster, Pennsylvania. The astronomers announced their findings in the September 27 issue of the online journal Science Express. The startling discovery came as WVU undergraduate student David Narkevic re-analyzed data from observations of the Small Magellanic Cloud made by the 210-foot Parkes radio telescope in Australia. The data came from a survey of the Magellanic Clouds that included 480 hours of observations. "This survey had sought to discover new pulsars, and the data already had been searched for the type of pulsating signals they produce," Lorimer said. "We re-examined the data, looking for bursts that, unlike the usual ones from pulsars, are not periodic," he added. The survey had covered the Magellanic Clouds, a pair of small galaxies in orbit around our own Milky Way Galaxy. Some 200,000 light-years from Earth, the Magellanic Clouds are prominent features in the Southern sky. Ironically, the new discovery is not part of these galaxies, but rather is much more distant

    Spontaneous grass covers are an inexpensive soil erosion control measure in olive orchards. Olive farmers allow grass to grow on sloping terrain to comply with the basic environmental standards derived from the Common Agricultural Policy (CAP). However, to date there are very few studies assessing the environmental quality and extent of such covers. In this study, we described and compared the biodiversity indicators associated to herbaceous vegetation in two contrasting olive orchards in order to evaluate its relevance and quality. In addition, biodiversity patterns and their relationships with environmental factors such as soil type and properties, precipitation, topography and soil management were analyzed. Different grass cover biodiversity indices were evaluated in two olive orchard catchments under conventional tillage and no tillage with grass cover, during 3 hydrological years (2011-2013). Seasonal samples of vegetal material and pictures in a permanent grid (4 samples ha-1) were taken to characterize the temporal variations of the number of species, frequency, diversity and transformed Shannon's and Pielou's indices. Sorensen's index obtained in the two olive orchard catchments showed notable differences in composition, probably linked with the different site conditions. The catchment with the best site conditions (deeper soil and higher precipitation), with average annual soil losses over 10 t ha-1 and a more intense management, presented the highest biodiversity indices. In absolute terms, the diversity indices were reasonably high in both catchments, despite the fact that agricultural activity usually severely limits the landscape and the variety of species. Finally, a significantly higher content of organic matter in the first 10 cm of soil was found in the catchment with the worst site conditions, average annual soil losses of 2 t ha-1 and the least intense management. Therefore, the biodiversity indicators associated to weeds were not found to be

    Full Text Available The impact of resources on social unrest is of increasing interest to political leaders, business and civil society. Recent events have highlighted that (lack of access to critical resources, including food, energy and water, can, in certain circumstances, lead to violent demonstrations. In this paper, we assess a number of political fragility indices to see whether they are good indicators of propensity to food riots. We found that the most accurate is the Political Instability and Absence of Violence Indicator of the Worldwide Governance Indicators by the World Bank. We compute a likelihood of experiencing a food riot for each quartile of this index. We found that the self-sufficiency of food does not seem to affect the likelihood of the occurrence of food riots, but that the level of political stability of a country does have a role. In addition, we identify a monthly and annual threshold for the Food and Agriculture Organisation Food Price Index, above which food riots in fragile states are more likely to occur.

    During the last decades most of the coastal zones across the Mediterranean Sea concentrates population around polescities owing to the mass movement of people from the rural areas to urban areas. The extensive tourism development across the coast generates demand of new work positions and pressurizes the environment. The economic development increase the natural capital of the study areas increase the covered with buildings and infrastructures areas and as a consequence reduce the quality of life. All the above effects modify the density of the buildings and infrastructures, push and eliminate the free green covered areas and other open spaces. In order to measure the effects on the environment and the quality of life a composite index is developed which arises using combined indices using economical, social and environmental criteria. The above components give a realistic indicator of the effects on the environment. This unique index arises as a function of the ratios of a per capital income a ratio of cover area by the uncovered area and the density of people per unit area. Usually when the wealth is increased the demand of energy and goods also increased and the damage on environment becomes bigger. This paper explores how the application of sustainability indices can be used as a tool to assess the quality of life. The use of GIS and remote sensing is highlighted to support the application of the existing sustainability indices.

    BACKGROUND: In many countries, quality indicators are used to assess the quality of care of family practice. Such assessments need to have an adequate precision, so that the results can be interpreted correctly. However, a small sample size per practitioner can lead to inadequate precision. A

    Full Text Available Knowledge-based economy has become a major trend in international society in the 21st century. However, today’s strategies place a greater emphasis on sustainability than in the past, while continuing to emphasize the importance of education and its connection with labour market. There has been a re-orientation, where resource, eco-efficiency and innovation have become major elements for achieving national objectives and a relevant level of competitiveness. This article deals with 30 indices, which define the competitiveness of a specific economy, and involve knowledge parameters. They are classified into four main categories and one special category. They are then analysed regarding the participation of Serbia and their availability. The main focus of this paper is to give detailed analyses of energy indices, as a special category of knowledge indexes. It has been shown that Serbia, in many cases, was not included in the study analysis or that there was insufficient information about Serbia’s position. This article shows that only a part of the presented indices includes Serbia. It is concluded that a new, revised model is needed that will include more exact indicators.
