    Full Text Available   ABSTRACT   Sambas traditional woven clothes produced in Sumber Harapan Village, Sambas Regency, are not known in neighboring sub-district and regency areas, but also in Pontianak City and even in Malaysia. Although many mid-scale and large organizations went bankrupt because of the tough economic crisis, this small-scale businesses remain operating without any serious hindrance. This proved that small-scale industries do not assign our government any burdens. Concerning this fact, it is recommended that these industries should be empowered. Underlined by these fact, this study is intend to investigate: (1 Some attempts of sambas woven clothes craftmen to raise their empowerment in order to optimize their business potentials, (2 Sambas Regency Government and private sector roles, and (3 sambas traditional woven clothes empowerment process in Sumber Harapan Village, Sambas Regency. The results identify that the craftmen attempts in optimizing their business potentials contain the following values: (a economical values, covering income raise, family welfare and family existence and their business; (b social values, covering aspects of increasing craftmen dignity and social status in which they should operate their own business instead of being workers; (c cultural values, covering their braveness, struggle, creativity, productivity and will to improve woven cloth design. The small-scale industries have provided economic sources, but they still cannot improve craftmen economic continuously. Sambas Regency Government roles as facilitator agency for the small-scale business has made some efforts by releasing some policies and small-scale industries empowerment. Unfortunately, these efforts has produced optimal outcome. To make the same efforts, private business offers partnership plan through merchandising and production patters. The craftmen empowerment is applied through three phases: initial, guidance, help, and establishment. The craftmen

    Full Text Available Abstract Background Recent healthcare policy has shifted the management of musculoskeletal conditions in the UK away from secondary care towards Clinical Assessment and Treatment Services at the primary-secondary care interface. However, little is known about the outcome of patients with musculoskeletal conditions referred from primary care to Clinical Assessment and Treatment Services or how best to identify those patients at high risk of poor outcome in this setting. We describe the protocol for a twelve-month prospective observational study which aims to describe the outcome of patients referred to musculoskeletal and back pain services at the primary-secondary care interface and to develop simple prognostic measures to guide clinical prioritisation and triage. Methods/Design All patients referred over a twelve-month period from primary care to musculoskeletal and back pain clinics in the primary-secondary care interface Clinical Assessment and Treatment Service in North Staffordshire will be mailed a postal questionnaire prior to their consultation. This will collect information on quality of life, general health, anxiety and depression, pain, healthcare utilisation including medication use, occupational characteristics, and socio-demographics. At the consultation in the interface clinic, the clinical diagnosis, investigations requested, and clinical interventions will be recorded. Follow-up data for the twelve-month period subsequent to recruitment will be collected via mailed follow-up questionnaires at 6 and 12 months, and review of medical records. Discussion This twelve-month prospective observational study of patients referred to a musculoskeletal Clinical Assessment and Treatment Service will assess the management and outcome of musculoskeletal care at the primary-secondary care interface as proposed in the Musculoskeletal Services Framework.

    Full Text Available Objectives: Wood dust is a known occupational allergen that may induce, in exposed workers, respiratory diseases including asthma and allergic rhinitis. Samba (obeche, Triplochiton scleroxylon is a tropical tree, which grows in West Africa, therefore, Polish workers are rarely exposed to it. This paper describes a case of occupational asthma caused by samba wood dust. Material and Methods: The patient with suspicion of occupational asthma due to wood dust was examined at the Department of Occupational Diseases and Clinical Toxicology in the Nofer Institute of Occupational Medicine. Clinical evaluation included: analysis of occupational history, skin prick tests (SPT to common and occupational allergens, determination of serum specific IgE to occupational allergens, serial spirometry measurements, metacholine challenge test and specific inhalation challenge test with samba dust. Results: SPT and specific serum IgE assessment revealed sensitization to common and occupational allergens including samba. Spirometry measurements showed mild obstruction. Metacholine challenge test revealed a high level of bronchial hyperactivity. Specific inhalation challenge test was positive and cellular changes in nasal lavage and induced sputum confirmed allergic reaction to samba. Conclusions: IgE mediated allergy to samba wood dust was confirmed. This case report presents the first documented occupational asthma and rhinitis due to samba wood dust in wooden airplanes model maker in Poland.

  6. Geochemical, microtextural and petrological studies of the Samba prospect in the Zambian Copperbelt basement: a metamorphosed Palaeoproterozoic porphyry Cu deposit.

    Ever since Wakefield (1978, IMM Trans., B87, 43-52) described a porphyry-type meta-morphosed Cu prospect, the ca 50 Mt, 0.5% Cu Samba deposit (12.717°S, 27.833°E), hosted by porphyry-associated quartz-sericite-biotite schists in northern Zambia, there has been controversy about its origin and significance. This is because it is situated in the basement to the world's largest stratabound sediment-hosted copper province, the Central African Copperbelt, which is hosted by rocks of the Neoproterozoic Katanga Supergroup. Mineralization in the pre-Katangan basement has long played a prominent role in ore genetic models, with some authors suggesting that basement Cu mineralization may have been recycled into the Katangan basin through erosion and redeposition, while others have suggested that the circulation of fluids through Cu-rich basement may have leached out the metals which are found concentrated in the Katangan orebodies. On the basis of ca 490-460 Ma Ar-Ar ages, Hitzman et al. (2012, Sillitoe Vol., SEG Spec. Publ., 16, 487-514) suggested that Samba represents late-stage impregnation of copper mineralization into the basement, and that it was one of the youngest copper deposits known in the Central African Copperbelt. If the Samba deposit really is that young, then it would have post-dated regional deformation and metamorphism (560-510 Ma), and it ought to be undeformed and unmetamorphosed. The Samba mineralization consists of chalcopyrite and bornite, occurring as disseminations, stringers and veinlets, found in a zone >1 km along strike, in steeply-dipping lenses up to 10m thick and >150m deep. Our new major and trace element XRF geochemical data (14 samples) show that the host rocks are mainly calc-alkaline metadacites. Cu is correlated with Ag (Cu/Ag ~10,000:1) with no Au or Mo. Our study focused on the microtextures and petrology of the Samba ores. We confirm that there is alteration of similar style to that accompanying classical porphyry Cu mineralization

    The connection of “groove” with low-level features in the audio signal has been mostly associated with temporal characteristics of fast metrical structures. However, the production and perception of rhythm in Afro-Brazilian contexts is often described as a result of multiple experience flows, which expands the description of rhythmical events to multiple features such as loudness, spectrum regions, metrical layers, movement and others. In this study, we analyzed how the microtiming of samba m...

  9. Samba and the other sambas: Instrumentation in different forms of Brazil's main musical genre

    Majlis, Pablo; Ilari, Beatriz

    2002-11-01

    The aim of the present paper is to describe the instruments of the different forms of samba, their origin, and their uses, focusing on percussion instruments. Samba is a Brazilian popular genre that developed mainly during the 20th century, though being deeply rooted in the precedent centuries of colonization and metissage between the Portuguese colonizers and the Africans that were brought as slaves. From its origins to the present day, samba has branched into multiple forms and instrumentation. Perhaps the most famous samba form is the samba enredo. This type of samba accompanies the Carnival parade in Rio de Janeiro, and features hundreds of percussionists. Another possible samba group instrumentation can be as simple as a single voice and a matchbox played by the singer. Between these two extremes there are several possible formations for a samba group, depending on the social context and function in which it occurs. Different group formations sometimes imply different song forms. Examples include samba de roda (i.e., circle samba), samba de gafieira (i.e., ballroom samba), and samba-cancao (i.e., samba ballad), among others. Some instruments will be available for attendees to try during the conference.

    Full Text Available Background Fungi are ubiquitous in nature, single celled or very complex multicellular organisms. Its distribution and their etiological agents varies with geographical location. The aim of the present study was to determine the clinical pattern of dermatophytosis and species of dermatophyte prevalent in district Samba, Jammu and Kashmir, India. Methods The present study was conducted in different hospitals of Jammu for the period of two years. All suspected patients with dermatophytoses, were included and specimens collected from them. The presence of fungal filaments by direct microscopy in KOH mount and culture was undertaken to isolate the fungal pathogen in each case. Results Among the 140 clinically suspected patients of dermatophytoses, 80% were positive for fungus in direct microscopy and 47.86% were culture positive. Tinea corporis was the most common clinical presentation followed by Tinea cruris. The commonest age group affected was 21–30 years (34.29% and the male to female ratio was 2.5:1. The predominant pathogen were Trichophyton rubrum (41.8% and Trichophyton tonsurans (22.4% followed by Trichophyton mentagrophytes (10.5%. Conclusion Anthropophilic species of genus Trichophyton dominated this study area. Trichophyton ruburm was the most common isolate followed by Trichophyton tonsurans. Direct microscopy and culture both should be done to increase the chances of definitive diagnosis in fungal infections

    2005-01-01

    We exploit the possibility of new configurations in three-body halo nuclei - Samba type - (the neutron-core form a bound system) as a doorway to Borromean systems. The nuclei $^{12}$Be, $^{15}$B, $^{23}$N and $^{27}$F are of such nature, in particular $^{23}$N with a half-life of 37.7 s and a halo radius of 6.36 fm is an excellent example of Samba-halo configuration. The fusion below the barrier of the Samba halo nuclei with heavy targets could reveal the so far elusive enhancement and a dominance of one-neutron over two-neutron transfers, in contrast to what was found recently for the Borromean halo nucleus $^6$He + $^{238}$U.

    Full Text Available Em 2005, o samba de roda, forma musical-coreográfica da região do Recôncavo, na Bahia, foi incluída pela Unesco na sua III Declaração de Obras-Primas do Patrimônio Imaterial da Humanidade. Essa candidatura vitoriosa foi construída num processo complexo, que envolveu agentes de políticas públicas, antropólogos, etnomusicólogos e, especialmente, sambadores e sambadoras do Recôncavo. A candidatura envolveu a elaboração de um Plano de Ação, previsto para cinco anos, para a salvaguarda do samba de roda no Recôncavo. No presente texto, depois de tratar brevemente do processo que levou à premiação da Unesco, são abordadas sobretudo questões suscitadas pela implementação do Plano de Ação, que se estruturou em torno de quatro "eixos": organização dos sambadores do Recôncavo, transmissão, difusão e documentação do samba de roda.In 2005, the samba de roda, a music-dance form from the Recôncavo region in Bahia, Brazil, was included in Unesco's Third Proclamation of the Intangible Heritage of Humanity. This award was the issue of a 20 months-long journey in wich public policy makers, anthropologists, ethnomusicologists and, specially, samba practitionners from Recôncavo were brought together. This included the writing of a Plan of Action, scheduled for five years, to safeguard samba de roda. In this paper, after a brief introduction on the process leading to Unesco's award, I will adress questions raised by the implementing of the Plan, which was built around four main themes: the organization of the sambadores; the transmission, diffusion and documentation of samba de roda.

The COBRAS/SAMBA maps will provide a major source of information relevant to several cosmological and astrophysical issues, such as testing theories of the early universe and the origin of cosmic structure. One of the main diffuse foreground emissions will be from interstellar dust, and the mission will provide relevant information on its components and emission properties. A combination of bolometric and radiometric detection techniques will ensure the sensitivity and wide spectral coverage required for accurate foreground discrimination. A far-Earth orbit has been selected to minimize the unwanted emission from the Earth as a source of contamination. The project is currently undergoing a feasibility study within the European Space Agency M3 programme.

  13. SAMBA: Sparse Approximation of Moment-Based Arbitrary Polynomial Chaos

    2016-09-01

    A new arbitrary Polynomial Chaos (aPC) method is presented for moderately high-dimensional problems characterised by limited input data availability. The proposed methodology improves the algorithm of aPC and extends the method, that was previously only introduced as tensor product expansion, to moderately high-dimensional stochastic problems. The fundamental idea of aPC is to use the statistical moments of the input random variables to develop the polynomial chaos expansion. This approach provides the possibility to propagate continuous or discrete probability density functions and also histograms (data sets) as long as their moments exist, are finite and the determinant of the moment matrix is strictly positive. For cases with limited data availability, this approach avoids bias and fitting errors caused by wrong assumptions. In this work, an alternative way to calculate the aPC is suggested, which provides the optimal polynomials, Gaussian quadrature collocation points and weights from the moments using only a handful of matrix operations on the Hankel matrix of moments. It can therefore be implemented without requiring prior knowledge about statistical data analysis or a detailed understanding of the mathematics of polynomial chaos expansions. The extension to more input variables suggested in this work, is an anisotropic and adaptive version of Smolyak's algorithm that is solely based on the moments of the input probability distributions. It is referred to as SAMBA (PC), which is short for Sparse Approximation of Moment-Based Arbitrary Polynomial Chaos. It is illustrated that for moderately high-dimensional problems (up to 20 different input variables or histograms) SAMBA can significantly simplify the calculation of sparse Gaussian quadrature rules. SAMBA's efficiency for multivariate functions with regard to data availability is further demonstrated by analysing higher order convergence and accuracy for a set of nonlinear test functions with 2, 5 and 10

    SAmBA is a new software for the design of minimal experimental protocols using the notion of orthogonal arrays of strength 2. The main application of SAmBA is the search of protein crystallization conditions. Given a user input defining the relevant effectors/variables (e.g., pH, temperature, salts) and states (e.g., pH: 5, 6, 7 and 8), this software proposes an optimal set of experiments in which all tested variables and the pairwise interactions between them are symmetrically sampled. No a priori restrictions on the number and range of experimental variables is imposed. SAmBA consists of two complementary programs, SAm and BA, using a simulated annealing approach and a backtracking algorithm, respectively. The software is freely available as C code or as an interactive JAVA applet at http:/(/)igs-server.cnrs-mrs.fr. PMID:9329089

    2013-09-01

    Full Text Available The interval between the Late Paleozoic and Early Mesozoic was marked by paleogeographic and paleoclimatic global changes, partly attributed to catastrophic events. The intense continentalization of the supercontinent Pangaea of End-Permian propitiated the development of extensive deserts that succeeded the coastal and platform environments of Early Permian. The records of these events in northern Brazil are found in intracratonic basins, particularly in the Permo-triassic succession of the Parnaíba Basin. The facies and stratigraphic outcrops analysis of this succession allowed the individualization of 14 sedimentary facies grouped into four facies associations (FA: FA1 and FA2 related to deposits of Motuca Formation and, FA3 and FA4, representative of the base of Sambaíba Formation. The FA1 – Shallow lake/Mudflat consists of red laminated mudstone with lenses of gypsum, calcite and marl, besides lobes of sigmoidal sandstones. The FA2 – Saline pan consists of lenticular bodies of laminated gypsum, nodular gypsum and gypsarenite, overlapped by greenish mudstones with dolomite nodules and palygorskite. The FA3 – sand sheet and FA4 – dunes field are formed, respectively, for orange cream sandstones with even parallel stratification and medium- to large-scale cross-bedding. In the contact between Motuca and Sambaíba formations occurs a deformed interval, laterally continuous for hundreds of kilometers. Brecciated and contorted bedded siltstones and mudstone (Motuca Formation and sandstone with sinsedimentary faults/microfaults, convolute lamination and mud-filled injection dykes (Sambaíba Formation are interpreted as seismites triggered by high magnitude earthquakes (> 8 according Richter scale.

  19. Lessons learnt from ten performance assessment studies

    International Nuclear Information System (INIS)

    The management of radioactive wastes and, in particular, the safety assessment of radioactive waste disposal systems are areas of high priority in the programme of the OECD Nuclear Energy Agency (NEA). In 1994, a Working Group was set up under the PAAG (Performance Assessment Advisory Group) on Integrated Performance Assessments of Deep Repositories (IPAG). The aim of the group is to provide a forum for informed discussion on performance assessment (PA), and to examine the overall status of PA and specific issues identified by the group and the PAAG. This document presents the report of a first phase of work completed in December 1996 and is expected to be of most interest to practitioners of repository PA and those with an interest in technical review of PA studies.

  20. Retardation mechanism studies for performance assessments

    International Nuclear Information System (INIS)

    Performance assessments of geological repositories for nuclear waste require information about how possibly escaping radionuclides will be transported through the bedrock. Retardation mechanism studies provide an important part of the database required. So far Finnish performance assessments have considered sorption and matrix diffusion as retardation mechanisms. In this report we discuss how the data supplied by experimental retardation mechanism studies meet those required by performance assessments in the Finnish case. Experimental structural studies on small-scale pore network are discussed in detail. The C-14-PMMA method and helium-gas methods provide porosity, diffusivity and permeability data. The effort within the Palmottu natural analogue project that aimed to locate large-scale flow channels is described briefly. Specific retardation mechanism studies are discussed. The laboratory studies cover column experiments and anion exclusion studies. Column experiments provide data on sorption and matrix diffusion. The natural analogue studies cover work done in the Palmottu, the Haemeenlinna boulder, and the Haestholmen projects. Studies at Palmottu provide in situ data about sorption and matrix diffusion. This review indicates that data required by current migration models in performance assessments can be met by existing experimental methods. But the situation changes if more detailed modelling is wanted. In that case, a strategic question must be answered: what is a reasonable level of detail and conceptual rigour in performance assessment modelling, considering the unavoidable overall uncertainties due to long time scales and heterogeneous bedrock? The results obtained so far in natural analogue studies indicate that there is room for improvements in sorption modelling. The current Kd based approach could be supported by parallel mechanistic sorption modelling. It is acknowledged, however, that mechanistic sorption modelling is possible for neither all

    Full Text Available In Malaysia, there has been rapidly increasing usage in amount of explosives due to widely expansion in quarrying and mining industries. The explosives are usually stored in the storage where the safety precaution had given high attention. As the storage of large quantity of explosive can be hazardous to workers and nearby residents in the events of accidental denotation of explosives, a risk assessment study for storage explosive (magazine had been carried out. Risk assessment study had been conducted in Kimanis Quarry Sdn. Bhd, located in Sabah. Risk assessment study had been carried out with the identification of hazards and failure scenarios and estimation of the failure frequency of occurrence. Analysis of possible consequences of failure and the effects of blast waves due to the explosion was evaluated. The risk had been estimated in term of fatalities and eardrum rupture to the workers and public. The average individual voluntary risk for fatality to the workers at the quarry is calculated to be 5.75 x 10-6 per person per year, which is much lower than the acceptable level. Eardrum rupture risk calculated to be 3.15 x 10-6 per person per year for voluntary risk. There is no involuntary risk found for fatality but for eardrum rupture it was calculated to be 6.98 x 10-8 per person per year, as given by Asian Development Bank.

  3. In the crossing of poetry and songs, it’s possible to learn “samba in school”

    Directory of Open Access Journals (Sweden)

    Juracy Assmann Saraiva

    2013-11-01

    Full Text Available The article proposes the inclusion of Brazilian popular music in disciplines that contemplate the study of the Language and the Literature, as a strategy to approximate the youth to the poetry. Songs, due to their way of circulating, invade the world of the youth and present them the formal characteristics of the lyric poetry, besides translating emotions and collective feelings. Under such angle, song and poetry do not distinguish themselves by their structural components, since both modalities can contain esthetic attributes. This point of view is sustained, in this article, by researchers such as Marisa Lajolo, Salete de Almeida Cara, Salvatore D’Onofrio and by the exposition of the poetry origin and its evolution, which prove that sonorous traces are presented in contemporaneous poems even that the register of the written word has provoked the rupture between the poetic art and the music. To prove the legitimacy of the convergence of poems and songs, the authors of this article analyze and interpret texts belonging to both genres, indicating common elements between them, such as the exploration of expressive resources of the language, that invoke the receptor’s participation in the deciphering of their meaning, and reflections about the human condition and about their circumstances. Therefore, the authors affirm that the reasons of esthetic and sociocultural order justify the inclusion of songs in the scholar ambit, since, such as the poems, they materialize the purpose of the art in conferring words to human feelings, while reaffirming the expressive potential of the lyric language.

  5. Analytical Similarity Assessment in Biosimilar Studies.

    Chow, Shein-Chung; Song, Fuyu; Bai, He

    2016-05-01

    For assessment of biosimilarity, the US Food and Drug Administration (FDA) recommends a stepwise approach for obtaining the totality-of-the-evidence for demonstrating biosimilarity between a proposed biosimilar product and an innovative (reference) biological product. The stepwise approach starts with analytical studies for functional and structural characterization at various stages of manufacturing process of the proposed biosimilar product. Analytical similarity assessment involves identification of critical quality attributes (CQAs) that are relevant to clinical outcomes. FDA proposes first classifying the identified CQAs into three tiers according to their criticality or risking ranking relevant to clinical outcomes and then performing equivalence test (for CQAs in Tier 1), quality range approach (for CQAs in Tier 2), and raw data or graphical presentation (for CQAs in Tier 3) for obtaining totality-of-the-evidence for demonstrating biosimilarity between the proposed biosimilar product with the reference product. In practice, some debatable issues are evitably raised due to this complicated process of analytical similarity assessment. In this article, these debatable are described and discussed.

    2001-01-01

    As part of NASA's Integrated Operations Architecture (IOA) Baseline, NASA will consolidate all communications operations. including ground-based, near-earth, and deep-space communications, into a single integrated network. This network will make maximum use of commercial equipment, services and standards. It will be an Internet Protocol (IP) based network. This study supports technology development planning for the IOA. The technical problems that may arise when LEO mission spacecraft interoperate with commercial satellite services were investigated. Commercial technology and services that could support the IOA were surveyed, and gaps in the capability of existing technology and techniques were identified. Recommendations were made on which gaps should be closed by means of NASA research and development funding. Several findings emerged from the interoperability assessment: in the NASA mission set, there is a preponderance of small. inexpensive, low data rate science missions; proposed commercial satellite communications services could potentially provide TDRSS-like data relay functions; and. IP and related protocols, such as TCP, require augmentation to operate in the mobile networking environment required by the space-to-ground portion of the IOA. Five case studies were performed in the technology assessment. Each case represented a realistic implementation of the near-earth portion of the IOA. The cases included the use of frequencies at L-band, Ka-band and the optical spectrum. The cases also represented both space relay architectures and direct-to-ground architectures. Some of the main recommendations resulting from the case studies are: select an architecture for the LEO/MEO communications network; pursue the development of a Ka-band space-qualified transmitter (and possibly a receiver), and a low-cost Ka-band ground terminal for a direct-to-ground network, pursue the development of an Inmarsat (L-band) space-qualified transceiver to implement a global, low

    This report documents some calculations performed to assess the Hydrogen Mixing Studies (HMS) code. Results are presented first for some analytical test problems, including laminar flow and mass diffusion. The von Karman vortex street problem and the Sandia FLAME Facility and Heiss Dampf Reaktor (HDR) containment facility test problems are then discussed. For the analytical problems, the code gave results that agree exceptionally well with the analytical solutions. Calculations for the von Karman vortex street problem were performed at selected Reynolds numbers for several obstacle types. The computed flow patterns agree well with experimental observations-specifically the occurrence of a vortex street (double row of vortices) above a critical Reynolds number. Calculations for the von Karman vortex street problem were performed at selected Reynolds numbers for several obstacle types. The computed flow patterns agree well with experimental observations-specifically the occurrence of a vortex street (double row of vortices) above a critical Reynolds number. The last assessment problem involves modeling the experiment T31.5. The experiment was carried out in the HDR containment building, which is a large, multi-compartment facility (11 300 m3 free volume in 72 compartments). In the experiment, a steam-water mixture was first injected into the containment to simulate a large-break blowdown of a pressure vessel, and then superheated steam was injected that was followed by a release of helium-hydrogen light gas. The calculated results (pressure, temperature, and gas concentrations) agree reasonably well with the experimental data

    Coastal waters, in particular, are the regions of high productivity and biodiversity. Detailed investigations of the variability within them can aid in understanding many biogeochemical processes. With the advent of hyperspectral remote sensing having large number of closely spaced channels and highly improved signal-to-noise ratio (SNR), the coastal applications are expected to increase and improve. In India, very less work is done in the field of coastal studies, let alone using hyperspectral remote sensing. HICO, onboard ISS, is the most recent addition to this family of instruments. So, a pilot study was conducted to assess HICO data for coastal studies especially in deriving the shallow water bathymetry estimates. The methodology for deriving bathymetry estimates is based on the different responses of shallow-water reflectance on depth and substrate type because with decreasing water depth in case 2 waters, the spectral contributions arriving from pure water reduce while from other OCAs increase. This variability is typically higher in the wavelength range 480 to 610 nm. Using this wavelength range, bathymetric estimates were made at pixel level. Bathymetry estimates were found to vary from 1 m to >12 m. Spectral variability is clearly observed in the continuum removed spectral plots from waters of different depths and is reported in this paper.

  10. System Losses and Assessment Trade Study

    International Nuclear Information System (INIS)

    This Advanced Fuel Cycle Initiative (AFCI) study has developed new analysis methods to examine old and new technology options toward the goal of improving fuel cycle systems. We have integrated participants and information from AFCI Systems Analysis, Transmutation Fuels, Separations, and Waste Form Campaigns in the Systems Losses and Assessment Trade Study. The initial objectives of this study were to (1) increase understanding of system interdependencies and thereby identify system trade-offs that may yield important insights, (2) define impacts of separations product purity on fuel manufacture and transmutation reactivity, (3) define impacts from transuranic (TRU) losses to waste, (4) identify the interrelationships involved in fuels and separations technology performance, and (5) identify system configuration adjustments with the greatest potential for influencing system losses. While bounding and analyzing this initial problem, we also identified significantly higher-level programmatic drivers with broad implications to the current fuel cycle research charter and the general issue of a DOE complex wide need for a comprehensive and integrated nuclear material management as addressed by the new DOE Order 410.2 titled 'Management of Nuclear Materials'. The initial modeling effort developed in this study for a much smaller subset of material (i.e., commercial fuel) and a selected transmutation scheme (i.e., fast reactor recycling) is a necessary first step towards examining a broader set of nuclear material management options, dispositioning strategies and integrated waste management options including potential areas of research leverage. The primary outcome from this initial study has been an enhanced integration among Campaigns and associated insights and analysis methods. Opportunities for improved understanding between the groups abound. The above lanthanide-actinide example highlights the importance of evaluating options via integration across the Campaigns

    Tokai, Akihiro

    Although, the staff for assessing environmental risk of chemicals is required in individual units of industrial sectors, there are very few systemic academic curriculums on risk assessment of chemicals in Japanese institutions of higher education. In order to meet such a social needs, Osaka University opened a limited-period program of environmental risk management for both students and working people in 2005. The author describes the contribution of his experience in offering a course on environmental risk assessment of chemicals as a part of the program. The course afforded students a kind of practical training for risk assessment. This paper also involves what to do for strengthening the education activity of risk assessment.

  19. Shift manager workload assessment - a case study

    International Nuclear Information System (INIS)

    In early 2003, Bruce Power restarted two of their previously laid up units in the Bruce A generating station, Units 3 and 4. However, due to challenges relating to the availability of personnel with active Shift Manager licenses, an alternate shift structure was proposed to ensure the safe operation of the station. This alternate structure resulted in a redistribution of responsibility, and a need to assess the resulting changes in workload. Atomic Energy of Canada Limited was contracted to perform a workload assessment based on the new shift structure, and to provide recommendations, if necessary, to ensure Shift Managers had sufficient resources available to perform their required duties. This paper discusses the performance of that assessment, and lessons learned as a result of the work performed during the Restart project. (author)

  20. Cooperative Student Assessment Method: an Evaluation Study

    2006-06-01

    Full Text Available Training through the Internet poses a series of technical problems and pedagogical issues. Traditional training is not indiscriminate but takes on different forms according to the needs of the subject being trained and the context where such training occurs. In order to make the systems adaptable in this way, a model of the student’s characteristics - the student model - has to be set up, maintained and updated. However, there are many difficulties involved in obtaining sufficient information to create an accurate student model. One way to solve this problem is to involve students in the student modeling process, stimulating them to provide the necessary information by means of a dialog in which the student and system build the student model according to a collaborative process. The present work describes a cooperative student modeling method (Cooperative Student Assessment - CSA which builds a joint system-student assessment of student’s activities on the basis of the student’s self-assessment ability estimation and a prototype system for children, addressing the learning of fractions, in which CSA is implemented. The article also reports the result of an experimentation carried out with learners attending primary school aiming at evaluating the effectiveness of involving students in the assessment process by comparing two versions of the same system: one using cooperative student modeling and the other the traditional overlay model.

    Bali, Anjana; Jaggi, Amteshwar Singh

    2015-01-01

    Stress is a state of threatened homeostasis during which a variety of adaptive processes are activated to produce physiological and behavioral changes. Stress induction methods are pivotal for understanding these physiological or pathophysiological changes in the body in response to stress. Furthermore, these methods are also important for the development of novel pharmacological agents for stress management. The well-described methods to induce stress in humans include the cold pressor test, Trier Social Stress Test, Montreal Imaging Stress Task, Maastricht Acute Stress Test, CO2 challenge test, Stroop test, Paced Auditory Serial Addition Task, noise stress, and Mannheim Multicomponent Stress Test. Stress assessment in humans is done by measuring biochemical markers such as cortisol, cortisol awakening response, dexamethasone suppression test, salivary α-amylase, plasma/urinary norepinephrine, norepinephrine spillover rate, and interleukins. Physiological and behavioral changes such as galvanic skin response, heart rate variability, pupil size, and muscle and/or skin sympathetic nerve activity (microneurography) and cardiovascular parameters such as heart rate, blood pressure, and self-reported anxiety are also monitored to assess stress response. This present review describes these commonly employed methods to induce stress in humans along with stress assessment methods. PMID:26020552

  4. Assessing biofuel crop invasiveness: a case study.

    Directory of Open Access Journals (Sweden)

    Christopher Evan Buddenhagen

    Full Text Available BACKGROUND: There is widespread interest in biofuel crops as a solution to the world's energy needs, particularly in light of concerns over greenhouse-gas emissions. Despite reservations about their adverse environmental impacts, no attempt has been made to quantify actual, relative or potential invasiveness of terrestrial biofuel crops at an appropriate regional or international scale, and their planting continues to be largely unregulated. METHODOLOGY/PRINCIPAL FINDINGS: Using a widely accepted weed risk assessment system, we analyzed a comprehensive list of regionally suitable biofuel crops to show that seventy percent have a high risk of becoming invasive versus one-quarter of non-biofuel plant species and are two to four times more likely to establish wild populations locally or be invasive in Hawaii or in other locations with a similar climate. CONCLUSIONS/SIGNIFICANCE: Because of climatic and ecological similarities, predictions of biofuel crop invasiveness in Hawaii are applicable to other vulnerable island and subtropical ecosystems worldwide. We demonstrate the utility of an accessible and scientifically proven risk assessment protocol that allows users to predict if introduced species will become invasive in their region of interest. Other evidence supports the contention that propagule pressure created by extensive plantings will exacerbate invasions, a scenario expected with large-scale biofuel crop cultivation. Proactive measures, such as risk assessments, should be employed to predict invasion risks, which could then be mitigated via implementation of appropriate planting policies and adoption of the "polluter-pays" principle.

  12. Occupational Exposure Assessment in Epidemiological Studies of EMF (invited paper)

    International Nuclear Information System (INIS)

    Numerous epidemiological studies have examined associations between occupational exposures to electric and magnetic fields (EMF) and adult cancers, with a particular focus on leukaemia and brain cancer. Meta-analyses that explored the patterns of these results with a particular emphasis on the qualitative aspects of exposure assessment are reviewed. Comparative analysis of the studies of electric utility employees are presented, along with an assessment of whether methodological differences among the studies might explain reported inconsistencies. Exposure assessment remains a foremost challenge in EMF studies. Most epidemiological studies have relied on magnetic field measurements linked to job titles. However, job titles alone explain only a small amount of variability in exposure. Recent results indicate that magnetic field exposure assessment should consider work environment in addition to job title to reduce exposure misclassification. The paper concludes with a discussion of numerous difficulties in occupational exposure assessment and offers suggestions for research. (author)

  16. Methodologic assessment of radiation epidemiology studies

    International Nuclear Information System (INIS)

    Epidemiologic studies of the late effects of ionizing radiation have utilized the entire spectrum of situations in which man has been exposed. These studies have provided insights into the dependence of human effects upon not only dose to target tissues but also other dimensions of exposure, host characteristics, and time following exposure. Over the past three decades studies have progressed from the mere identification of effects to their measurement. Because investigators of human effects have no control over the exposure situation, validity must be sought in the consistency of findings among independent studies and with accepted biologic principles. Because exposure may be confounded with factors that are hidden from view, bias may enter into any study of human exposure. Avoidance of bias and attainment of sufficient power to detect relationships that are real are methodologic challenges. Many methodologic issues, e.g., those associated with the definition and measurement of specific end-points, or with the selection of appropriate controls, permeate epidemiologic work in all fields. Others, especially those concerned with the measurement of exposure, the patterning of events in time after exposure, and the prediction of events beyond the scope of existing observations give radiation epidemiology its distinctive character

    Full Text Available Problem statement: This study aims at evaluating corresponding banks in Jordan. Characterizing the goals, instruments and profitability under unfavorable conditions of financial setbacks and unfair competition among banks. Focuses on the feasibility and profitability of Philadelphia Investment Bank in its international trade via its Correspondent banks. Approach: Problems and setbacks shall be screened out; reasoned and appropriate optimal recommendations are to be presented. Results: The study followed the analytical approach and depended on “History Documents” and “In depth Interview” techniques and puts a major emphasis on the fact that correspondent banking has become an essential cornerstone of international business amid the new era of world trade, globalization, external competition and cartels from the major opponents to Jordanian Banks, the main conclusion is realized the importance of correspondent banks in the international trade, so Philadelphia bank benefited from correspondent banks for the cheap cost of market entry and services were tailored to the scale of required locale. But there was no big investment in staff facilities. And there are setbacks in dealing with correspondent banks, such as fund delay in reaching destinations on time. Moreover, Jordanian banks have suffered in general from these correspondent banks because they deal with these correspondent banks individually. Conclusion/Recommendations: The recommendation of the study is, it is the time to consider solidification and forming one financial block, or a sort of cartel and face these correspondent banks in one unit. They are also called for developing collective strategies. Small banks should merge and form huge capital blocks. Another strategy is that Jordanian banks should minimize the reliance on foreign banks and should develop their own, by establishing international branches abroad to help financing their international activities.

    2009-12-01

    Full Text Available Abstract Background The quantification of uncertainty and variability is a key component of quantitative risk analysis. Recent advances in Bayesian statistics make it ideal for integrating multiple sources of information, of different types and quality, and providing a realistic estimate of the combined uncertainty in the final risk estimates. Methods We present two case studies related to foodborne microbial risks. In the first, we combine models to describe the sequence of events resulting in illness from consumption of milk contaminated with VTEC O157. We used Monte Carlo simulation to propagate uncertainty in some of the inputs to computer models describing the farm and pasteurisation process. Resulting simulated contamination levels were then assigned to consumption events from a dietary survey. Finally we accounted for uncertainty in the dose-response relationship and uncertainty due to limited incidence data to derive uncertainty about yearly incidences of illness in young children. Options for altering the risk were considered by running the model with different hypothetical policy-driven exposure scenarios. In the second case study we illustrate an efficient Bayesian sensitivity analysis for identifying the most important parameters of a complex computer code that simulated VTEC O157 prevalence within a managed dairy herd. This was carried out in 2 stages, first to screen out the unimportant inputs, then to perform a more detailed analysis on the remaining inputs. The method works by building a Bayesian statistical approximation to the computer code using a number of known code input/output pairs (training runs. Results We estimated that the expected total number of children aged 1.5-4.5 who become ill due to VTEC O157 in milk is 8.6 per year, with 95% uncertainty interval (0,11.5. The most extreme policy we considered was banning on-farm pasteurisation of milk, which reduced the estimate to 6.4 with 95% interval (0,11. In the second

    DeShong, Hilary L; Helle, Ashley C; Mullins-Sweatt, Stephanie N

    2016-05-01

    The current study investigated original case descriptions of psychopathy (Cleckley, 1941) in relation to current conceptualizations and general personality traits. Attorneys, forensic psychologists and clinical faculty members completed ratings of psychopathy and personality after reading vignettes based on Cleckley's descriptions of a psychopath. The results suggest that professionals' ratings are consistent with current conceptualizations of psychopathy. Furthermore, the five-factor model (FFM) personality traits of the vignettes aligned with the current literature on the FFM and psychopathy (i.e. low neuroticism, conscientiousness and agreeableness). The results further supported that a general trait model, like the FFM, may be well suited to describe the underlying personality traits of psychopathy. Gender differences were also examined.

  17. Assessing the first wave of epidemiological studies of nanomaterial workers

    International Nuclear Information System (INIS)

    The results of early animal studies of engineered nanomaterials (ENMs) and air pollution epidemiology suggest that it is important to assess the health of ENM workers. Initial epidemiological studies of workers’ exposure to ENMs (<100 nm) are reviewed and characterized for their study designs, findings, and limitations. Of the 15 studies, 11 were cross-sectional, 4 were longitudinal (1 was both cross-sectional and longitudinal in design), and 1 was a descriptive pilot study. Generally, the studies used biologic markers as the dependent variables. All 11 cross-sectional studies showed a positive relationship between various biomarkers and ENM exposures. Three of the four longitudinal studies showed a negative relationship; the fourth showed positive findings after a 1-year follow-up. Each study considered exposure to ENMs as the independent variable. Exposure was assessed by mass concentration in 10 studies and by particle count in six studies. Six of them assessed both mass and particle concentrations. Some of the studies had limited exposure data because of inadequate exposure assessment. Generally, exposure levels were not very high in comparison to those in human inhalation chamber studies, but there were some exceptions. Most studies involved a small sample size, from 2 to 258 exposed workers. These studies represent the first wave of epidemiological studies of ENM workers. They are limited by small numbers of participants, inconsistent (and in some cases inadequate) exposure assessments, generally low exposures, and short intervals between exposure and effect. Still, these studies are a foundation for future work; they provide insight into where ENM workers are experiencing potentially adverse effects that might be related to ENM exposures

    The science of exposure assessment is relatively new and evolving rapidly with the advancement of sophisticated methods for specific measurements at the picogram per gram level or lower in a variety of environmental and biologic matrices. Without this measurement capability, environmental health studies rely on questionnaires or other indirect means as the primary method to assess individual exposures. Although we use indirect methods, they are seldom used as stand-alone tools. Analyses of en...

  1. Deep geologic disposal. Lessons learnt from recent performance assessment studies

    International Nuclear Information System (INIS)

    Performance assessment (PA) studies are part of the decision basis for the siting, operation, and closure of deep repositories of long-lived nuclear wastes. In 1995 the NEA set up the Working Group on Integrated Performance Assessments of Deep Repositories (IPAG) with the goals to analyse existing PA studies, learn about what has been produced to date, and shed light on what could be done in future studies. Ten organisations submitted their most recent PA study for analysis and discussion, including written answers to over 70 questions. Waste management programmes, disposal concepts, geologies, and different types and amounts of waste offered a unique opportunity for exchanging information, assessing progress in PA since 1990, and identifying recent trends. A report was completed whose main lessons are overviewed. (author)

    2005-01-01

    @@ Introduction TERMINOLOGY AND KEY CONCEPTS The term assessment refers to a variety of ways of collecting information on a learner's language ability or achievement. Although testing and assessment are often used interchangeably, the latter is an umbrella term encompassing measurement instruments administered on a ‘one-off’ basis such as tests, as well as qualitative methods of monitoring and recording student learning such as observation, simulations of project work. Assessment is also distinguished from evaluation which is concerned with the overall language programme and not just with what individual students have learnt. Proficiency assessment refers to the assessment of general language abilities acquired by the learner independent of a course of study.This kind of assessment is often done through the administration of standardised commercial language-proficency tests. On the other hand, assessment of achievement aims to establish what a student had learned in relation to a particular course or curriculum (thus frequently carried out by the teacher) .Achievement assesssment may be based either on the specific content of the course or on the course objectives (Hughes 1989).

    This study investigated the different ways of evaluating the social support in Brazilian studies. A surveying of scientific Brazilian publications from 1987 to 2007 was done in the Indexpsi, Pepsic, SciELO and Lilacs databases according to keywords social support and social network. Fifty-five studies included some type of assessing social support in Brazilian samples. The results indicated a rise in the number of studies about social support assessment in the last years using interviews to investigate received and perceived support, predominantly. However, the construction was applied without theoretical basis and was associated with many other concepts, sometimes without an appropriate articulation. Besides, there were evidences of lacking reliable, valid and standardized instruments to Brazilian population by considering the instruments currently used and revised by this study. PMID:21519666

    A main source of outdoor air pollution is road traffic, which produces a complex mixture of nitrogen oxides, carbon monoxide, volatile hydrocarbons, airborne particles and some other compounds. Traffic exhaust affects also the concentrations of ozone and other photo chemical oxidants. In earlier studies those components have had remarkable health effects. Several studies on occupational exposure to automobile exhaust have been published and several studies have been observed an association between both outdoor and indoor pollutant levels and health outcomes. However, there are only a few epidemiological studies in which traffic exhaust, a complex mixture, has been studied in its entirety. During recent years, interesting epidemiological studies of the health effects of this complex mixture have been published. Human exposure assessment for traffic exhaust can be categorized according to the environment of exposure (indoors, outdoors, in-traffic) or to the method of exposure assessment (direct or indirect methods). In this presentation the methods are further categorized into (1) traffic activity, (2) air concentration measurements, and (3) dispersion models, in order to better understand the advantages and disadvantages of different approaches. The objective of this presentation is to make a critical review of exposure assessments in the epidemiological studies on health effects of traffic exhaust. (author)

    Full Text Available At the moment, the health-environmental risk analysis is used to decision-making targets in the contaminated sites management; this procedure allows to assess the quantitative health risk related to the pollutants presence in environmental compartments, as soil and waters. As regards potentially contaminated agricultural soils, the ingestion of food from vegetable and/or animal source, produced inside the contaminated area, is the most suitable way to assess the health risk. As an official procedure to this assessment is not available, the National Institute for Health (Istituto Superiore di Sanità, ISS has worked out an operating procedure, organized into several phases, depending on the available specific-site know-how. In this document, agricultural soils potentially contaminated in two sites have been studied; the sites are the following: Brescia Caffaro and Torviscosa.

    Ginsberg, Gary; Ginsberg, Justine; Foos, Brenda

    2016-01-01

    Children's exposure assessment is a key input into epidemiology studies, risk assessment and source apportionment. The goals of this article are to describe a methodology for children's exposure assessment that can be used for these purposes and to apply the methodology to source apportionment for the case study chemical, diethylhexylphthalate (DEHP). A key feature is the comparison of total (aggregate) exposure calculated via a pathways approach to that derived from a biomonitoring approach. The 4-step methodology and its results for DEHP are: (1) Prioritization of life stages and exposure pathways, with pregnancy, breast-fed infants, and toddlers the focus of the case study and pathways selected that are relevant to these groups; (2) Estimation of pathway-specific exposures by life stage wherein diet was found to be the largest contributor for pregnant women, breast milk and mouthing behavior for the nursing infant and diet, house dust, and mouthing for toddlers; (3) Comparison of aggregate exposure by pathways vs biomonitoring-based approaches wherein good concordance was found for toddlers and pregnant women providing confidence in the exposure assessment; (4) Source apportionment in which DEHP presence in foods, children's products, consumer products and the built environment are discussed with respect to early life mouthing, house dust and dietary exposure. A potential fifth step of the method involves the calculation of exposure doses for risk assessment which is described but outside the scope for the current case study. In summary, the methodology has been used to synthesize the available information to identify key sources of early life exposure to DEHP. PMID:27376320

  17. Preliminary Study on Conducting Experiments for Assessment of Secondary Stresses

    International Nuclear Information System (INIS)

    In order to validate the new procedure for assessment of cracks in ductile materials with presence of high secondary stresses, access to the experimental results is needed. Such experimental results are very limited in the published literature. In this report, different test options are studied in order to find a proper test program to study the effects of secondary stresses at high levels of primary stresses. These options consider the use of thermal transients or welding residual stresses in the test program. A total of 36 different cases considering crack configuration, type of thermal transient and the level of mechanical loading are studied here. The fracture assessments of these cases are conducted based on the R6-method. Based on the assessment results conducted in this study, the following options are proposed for conducting the test program: Option 1: To use a thermal transient with T0 = 200 deg C and h = 5 kW/m2 deg C on edge surface cracked plates with a/t = 0.3 subjected to a mechanical bending of σb/σY > 0.8. Option 2: To use welding residual stresses on edge surface cracked plates with a/t 0.3 subjected to a mechanical bending of σb/σY > 0.6. Option 3: To use mechanically induced residual stresses (in-plane compression) in edge surface cracked specimens subjected to a mechanical bending

    The purpose of this clinical feasibility study was to evaluate the applicability of magnetic resonance imaging (MRI) for the assessment of apical periodontitis in direct comparison with cone beam CT (CBCT). 19 consecutive patients (average age 43 ± 13 years) with 34 lesions in total (13 molars, 14 premolars and 7 front teeth) were enrolled in this feasibility study. Periapical lesions were defined as periapical radiolucencies (CBCT) or structural changes in the spongy bone signal (MRI), which were connected with the apical part of a root and with at least twice the width of the periodontal ligament space. The location and dimension of the lesions were compared between MRI and CBCT. While mainly mineralized tissue components such as teeth and bone were visible with CBCT, complimentary information of the soft tissue components was assessable with MRI. The MRI images provided sufficient diagnostic detail for the assessment of the main structures of interest. Heterogeneous contrast was observed within the lesion, with often a clear enhancement close to the apical foramen and the periodontal gap. No difference for lesion visibility was observed between MRI and CBCT. The lesion dimensions corresponded well, but were slightly but significantly overestimated with MRI. A heterogeneous lesion appearance was observed in several patients. Four patients presented with a well circumscribed hyperintense signal in the vicinity of the apical foramen. The MRI capability of soft tissue characterization may facilitate detailed analysis of periapical lesions. This clinical study confirms the applicability of multi-contrast MRI for the identification of periapical lesions.

    Severe burn injuries can require escharotomies which are urgent, infrequent, and relatively high-risk procedures necessary to preserve limb perfusion and sometimes ventilation. The American Burn Association Advanced Burn Life Support© course educates surgeons and emergency providers about escharotomy incisions but lacks a biomimetic trainer to demonstrate, practice, or provide assessment. The goal was to build an affordable biomimetic trainer with discrete points of failure and pilot a validation study. Fellowship-trained burn and plastic surgeons worked with special effect artists and anatomists to develop a biomimetic trainer with three discrete points of failure: median or ulnar nerve injury, fasciotomy, and failure to check distal pulse. Participants were divided between experienced and inexperienced, survey pre- and post-procedure on a biomimetic model while being timed. The trainer total cost per participant was less than $35. Eighteen participants were involved in the study. The inexperienced (0-1 prior escharotomies performed) had significantly more violations at the discrete points of failure relative to more experienced participants (P = .036). Face validity was assessed with 100% of participants agreement that the model appeared similar to real life and was valuable in their training. Given the advancements in biomimetic models and the need to train surgeons in how to perform infrequent, emergent surgical procedures, an escharotomy trainer is needed today. The authors developed an affordable model with a successful pilot study demonstrating discrimination between experienced and inexperienced surgeons. Additional research is needed to increase the reliability and assessment metrics. PMID:26594860

  4. Assessment of apical periodontitis by MRI. A feasibility study

    International Nuclear Information System (INIS)

    The purpose of this clinical feasibility study was to evaluate the applicability of magnetic resonance imaging (MRI) for the assessment of apical periodontitis in direct comparison with cone beam CT (CBCT). 19 consecutive patients (average age 43 ± 13 years) with 34 lesions in total (13 molars, 14 premolars and 7 front teeth) were enrolled in this feasibility study. Periapical lesions were defined as periapical radiolucencies (CBCT) or structural changes in the spongy bone signal (MRI), which were connected with the apical part of a root and with at least twice the width of the periodontal ligament space. The location and dimension of the lesions were compared between MRI and CBCT. While mainly mineralized tissue components such as teeth and bone were visible with CBCT, complimentary information of the soft tissue components was assessable with MRI. The MRI images provided sufficient diagnostic detail for the assessment of the main structures of interest. Heterogeneous contrast was observed within the lesion, with often a clear enhancement close to the apical foramen and the periodontal gap. No difference for lesion visibility was observed between MRI and CBCT. The lesion dimensions corresponded well, but were slightly but significantly overestimated with MRI. A heterogeneous lesion appearance was observed in several patients. Four patients presented with a well circumscribed hyperintense signal in the vicinity of the apical foramen. The MRI capability of soft tissue characterization may facilitate detailed analysis of periapical lesions. This clinical study confirms the applicability of multi-contrast MRI for the identification of periapical lesions.

  6. HERMES docking/berthing system pilot study. Quantitative assessment

    International Nuclear Information System (INIS)

    This study falls within the framework of the incorporation of quantitative risk assessment to the activities planned for the ESA-HERMES project (ESA/ CNES). The main objective behind the study was the analysis and evaluation of the potential contribution of so-called probabilistic or quantitative safety analysis to the optimization of the safety development process for the systems carrying out the safety functions required by the new and complex HERMES Space Vehicle. For this purpose, a pilot study was considered a good start in quantitative safety assessments (QSA), as this approach has been frequently used in the past to establish a solid base in large-scale QSA application programs while avoiding considerable economic risks. It was finally decided to select the HERMES docking/berthing system with Man Tender Free Flyer as the case-study. This report describes the different steps followed in the study, along with the main insights obtained and the general conclusions drawn from the study results. (author)

  7. Treatment of operator actions in the HTGR risk assessment study

    International Nuclear Information System (INIS)

    Methods are presented for the treatment of operator actions, developed in the AIPA risk assessment study. Some examples are given of how these methods were applied to the analysis of potential HTGR accidents. Realistic predictions of accident risks required a balanced treatment of both beneficial and detrimental actions and responses of human operators and maintenance crews. Th essential elements of the human factors methodology used in the AIPA study include event tree and fault tree analysis, time-dependent operator response and repair models, a method for quantifying common cause failure probabilities, and synthesis of relevant experience data for use in these models

    2007-01-01

    attempt has been made to capture the new trends in the regulations, to the extent they are known. There have over the last 10-15 years been published a few textbooks on risk assessment, most of them are devoted to relatively generic topics. Some are also focused on the risk management aspects, in general and with offshore applicability. None are known to address the needs and topics of the use of QRA studies by the offshore industry in particular. The present work is trying to bridge this gap. The use of QRA studies is somewhat special in Northern Europe, and par- cularly in Norway. The use of

    2009-01-01

    This paper proposes an approach to the implementation of a large-scale epidemiological study of child development. It addresses specifically how one might assess gross motor development longitudinally in a large population-based study of children, and recommends a three-phase process. Phase I, applied at key ages with the entire population, involves the use of parent-report screening tools that ask about specific age-appropriate motor skills, as well as any parental concerns about "quantity" or "quality" of their child's motor function and about any loss of motor function. In phase II, children who "fail" the screening phase (at any stage) are evaluated with specified developmental motor assessments. Those who "pass" revert to the screening stream, while those who "fail" continue to phase III. In this third component of the study, children are referred to experts in child development formally engaged in the study (including developmental paediatricians, paediatric neurologists and developmental therapists). These experts will use protocol-based evaluations to ascertain whether a child has a problem in development, what the problem might be from a diagnostic perspective, how "severe" the problem is, and what management services are or should be provided. It is argued that this is an efficient approach to the study of a population that would enable investigators to detect specific relatively common developmental motor disorders (in particular, cerebral palsy and developmental coordination disorder).

    The overall objectives of this study are to determine the market potential and the technical feasibility of using PFBC ash in high volume ash use applications. The information will be of direct use to the utility industry in assessing the economics of PFBC power generation in light of ash disposal avoidance through ash marketing. In addition, the research is expected to result in the generation of generic data on the use of PFBC ash that could lead to novel processing options and procedures. The specific objectives of the proposed research and demonstration effort are: Define resent and future market potential of PFBC ash for a range of applications (Phase I); assess the technical feasibility of PFBC ash use in construction, civil engineering and agricultural applications (Phase II); and demonstrate the most promising of the market and ash use options in full-scale field demonstrations (Phase III).

  11. Wuskwatim generation project : Canadian Environmental Assessment Act comprehensive study report

    International Nuclear Information System (INIS)

    This study report described the plan by Manitoba Hydro and the Nisichawayasihk Cree Nation (NCN) to construct a new 200- megawatt (MW) generating station at Taskinigup Falls on the Burntwood River, near the outlet of Wuskwatim Lake. This hydroelectric power project will allow Manitoba Hydro to meet its projected energy needs within the next two decades as identified in its 2002/03 Power Resource Plan. It will also allow Manitoba Hydro and NCN to obtain additional export revenues and profits by advancing the in-service date of the Project from 2020 to 2009. A formal environmental assessment is required under the Canadian Environmental Assessment Act (CEAA) because Fisheries and Oceans Canada (DFO) has determined that the Project would cause fish habitat losses requiring an authorization under the Fisheries Act. Many of the structures to be built in navigable waters would also require formal approval under the Navigable Waters Protection Act (NWPA), which has prompted this application of the CEAA. This environmental assessment report has been prepared by DFO in consultation with Transport Canada and other federal authorities concerned. It provides a summary of the Wuskwatim Generation Project and the environment in which it will be built and operated. In addition, the results of public consultations are discussed. It presents an assessment of the Project's influence on fish and fish habitat, birds, species at risk, human health (local air quality, quality of drinking water and consumption of fishery products), navigation, use of renewable resources, and current use of lands and resources for traditional purposes by Aboriginal persons (hunting, trapping, gathering, subsistence fishing and heritage sites). It was concluded that the proposed Project, as defined by the scope of the study, is not likely to cause significant adverse environmental effects. 45 refs., 5 tabs., 13 figs., 3 appendices

    In March 2011, the U.S. Department of Energy (DOE) awarded White Pine County, Nevada, a grant to assess the feasibility of renewable resource-related economic development activities in the area. The grant project included a public outreach and training component and was to include a demonstration project; however, the demonstration project was not completed due to lack of identification of an entity willing to locate a project in White Pine County. White Pine County completed the assessment of renewable resources and a feasibility study on the potential for a renewable energy-focused economic sector within the County. The feasibility study concluded "all resources studied were present and in sufficient quantity and quality to warrant consideration for development" and there were varying degrees of potential economic impact based on the resource type and project size. The feasibility study and its components were to be used as tools to attract potential developers and other business ventures to the local market. White Pine County also marketed the County’s resources to the renewable energy business community in an effort to develop contracts for demonstration projects. The County also worked to develop partnerships with local educational institutions, including the White Pine County School District, conducted outreach and training for the local community.

    In August 1978, the United States Department of Energy and the Turlock Irrigation District entered into a cooperative agreement for a Joint District's Low-Head Hydropower Assessment Study. The purpose of the agreement was to carry out a study of the hydropower potential at sites within the borders of the Turlock, Merced, South San Joaquin, and Oakdale Irrigation Districts in California. The required data were gathered and analyzed. The results of this study indicate the total potential small hydropower capacity with the Joint Districts is 19,560 kW installed with an annual energy generation of 68,561,800 kWh. This is equivalent to oil-savings of 118,616 barrels per y.

  15. Seismic probabilistic risk assessment and its impact on margin studies

    International Nuclear Information System (INIS)

    In recent years a number of seismic probabilistic risk assessments of nuclear power plants have been conducted. These studies have highlighted the significance of seismic events to the overall plant risk and have identified several dominant contributors to the seismic risk. It has been learnt from the seismic PRAs that the uncertainty in the seismic hazard results contribute to the large uncertainty in the core damage and severe release frequencies. A procedure is needed to assess the seismic safety of a plant which is somewhat removed from the influence of the uncertainties in seismic hazard estimates. In the last two years, seismic margin review methodologies have been developed based on the results and insights from the seismic probabilistic risk assessments. They focus on the question of how much larger an earthquake should be beyond the plant design basis before it compromises the safety of the plant. An indicator of the plant seismic capacity called the High Confidence Low Probability of Failure (HCLPF) capacity, is defined as the level of earthquake for which one could state with high confidence that the plant will have a low probability of severe core damage. The seismic margin review methodologies draw from the seismic PRAs, experience in seismic analyses, testing and actual earthquakes in order to minimize the review effort. The salient steps in the review consists of preliminary screening of components and systems, performance of detailed seismic walkdowns and evaluation of seismic margins for components, systems and plant.

    Full Text Available The inherent complexity of environmental performance measurement makes it difficult to be gauged, sending it forth to methodologies supported on assessments of the various factors that could influence the overall performance. In association with the environmental performance lies the need to create methods that allows the assessment over the time in order to facilitate comparisons amongst different organizations or operations of a same company. Measurement of environmental performance comes from several sources thus a dominant approach widely recognized and accepted by the academic community and organizations can not be singled out. The purpose of this review is to test a method for assessing environmental performance in a manufacturer organization, performing a case study in the paper industry. The results can be compared with other operations and can be used, cumulatively, in supply chains. The specific objectives are (i to model the environmental performance of the transaction, (ii to use the model to measure performance, and (iii to interpret the results and come to a conclusion. It begins with a review of the environmental performance measurement and then proceeds to the description of the research methodology and the results of its application. The method consists of five constructs, assessed by managers and processes experts according to their potential of environmental performance's improvement: solid waste, wastewater, gas emissions, deployment of natural resources, and legal compliance. The constructs are perceived by qualitative indicators categorically evaluated. The final result is an index of 76.69%, which represents the environmental performance of the operation.

    Full Text Available Rhinoplasty is one of the most common cosmetic surgery performed by the otorhinolaryngologists. The main indication for rhinoplasty is cosmetic or functional or both. In regard to paucity of research regarding patient satisfaction after surgery, we have done this prospective clinical study in our hospital. 40 patients were included in the study from January 2012 to December 2012. Rhinoplasty Outcomes Evaluation (ROE Questionnaire was applied to all the patients and evaluation of the satisfaction pre op and post operatively was assessed and the results were statistically analysed. The age of the study group ranged from 20 yrs to 39 yrs with the mean age of 24.85 +/- 3.43 years. The average satisfaction mark of patients undergoing rhinoplasty in pre-operative state was 28.05 & post-operative it improved and reached to 67.91.The average satisfaction of female were 26.75 preoperatively reached to 63.68 postoperatively. The average satisfaction of male were 31.2 preoperatively reached upto 67.91 post operatively. The degree of the satisfaction pre and post operatively was compared using student t test and paired t test. It was 67.91 in males and 36.53 among females which was statistically significant (p < 0.05. Patient satisfaction is as important as technical aspects of rhinoplasty. Hence a novel attempt is made in this direction to assess and understand patient expectations to achieve realistic goals in rhinoplasty.

  20. Assessment of international mitigation costing studies in developing countries

    International Nuclear Information System (INIS)

    The establishment of the Framework Convention on Climate change has motivated a large number of mitigation costing studies of developing countries. A variety of modelling approaches and input assumptions have been employed, and studies have been carried out by a range of institutions, including international research institutions, consultants and national organisations. This paper attempts to bring together the main results and characteristics of some of the major recent studies. In spite of the diversity of teams involved in the studies, the similarities in scenario definitions and in the bottom-up approach used for the energy sector analysis, enable some key macro indicators and results of the studies to be compared. Two main coordinated country study efforts have been carried out: by the Lawrence Berkeley Laboratory (LBL) and by UNEP collaborating Centre on Energy and Environment (UCCEE). The results and methodological framework of these country studies are assessed in relation to similar country study activities for China, West Africa and South East Asia in order to evaluate possible common conclusions.

  1. Life cycle assessment study of a Chinese desktop personal computer

    International Nuclear Information System (INIS)

    Associated with the tremendous prosperity in world electronic information and telecommunication industry, there continues to be an increasing awareness of the environmental impacts related to the accelerating mass production, electricity use, and waste management of electronic and electric products (e-products). China's importance as both a consumer and supplier of e-products has grown at an unprecedented pace in recent decade. Hence, this paper aims to describe the application of life cycle assessment (LCA) to investigate the environmental performance of Chinese e-products from a global level. A desktop personal computer system has been selected to carry out a detailed and modular LCA which follows the ISO 14040 series. The LCA is constructed by SimaPro software version 7.0 and expressed with the Eco-indicator'99 life cycle impact assessment method. For a sensitivity analysis of the overall LCA results, the so-called CML method is used in order to estimate the influence of the choice of the assessment method on the result. Life cycle inventory information is complied by ecoinvent 1.3 databases, combined with literature and field investigations on the present Chinese situation. The established LCA study shows that that the manufacturing and the use of such devices are of the highest environmental importance. In the manufacturing of such devices, the integrated circuits (ICs) and the Liquid Crystal Display (LCD) are those parts contributing most to the impact. As no other aspects are taken into account during the use phase, the impact is due to the way how the electricity is produced. The final process steps - i.e. the end of life phase - lead to a clear environmental benefit if a formal and modern, up-to-date technical system is assumed, like here in this study

    Full Text Available The use of secondary metrics has become special interest in bioequivalency studies. The applicability of partial area method, truncated AUC and Cmax/AUC has been argued by many authors. This study aims to evaluate the possible superiority of these metrics to primary metrics (i.e. AUCinf, Cmax and Tmax. The suitability of truncated AUC for assessment of absorption extent as well as Cmax/AUC and partial AUC for the evaluation of absorption rate in bioequivalency determination was investigated following administration of same product as test and reference to 7 healthy volunteers. Among the pharmacokinetic parameters obtained, Cmax/AUCinf was a better indicator or absorption rate and the AUCinf was more sensitive than truncated AUC in evaluation of absorption extent.

    Topographical disorientation refers to individuals who are unable to find their way around large-scale environments in a normal manner. Childhood topographical disorientation is rarely investigated or reported. Treatment of topographical disorientation is also rare with only one reported treatment study in an adult (Davis & Coltheart, 1999) and no known description of treatment in a child. This paper reports a detailed case analysis of CA, a 6-year-old child with topographical disorientation, and a description of a treatment programme focused on training orientation in the school environment. Assessment of CA revealed mild to moderate visual agnosia in conjunction with severe impairments in general spatial learning and memory, topographical new learning and memory, and a total inability to learn new topographical routes. CA was also unable to use a mental image of his environment, a simple visual plan of his environment or a simple visual map, but was able to follow verbally mediated topographical instructions. The treatment programme focused on improving CA's topographical orientation in the school environment. The programme first involved training in recognition of major school buildings and landmarks and then focused on practical training in route finding along commonly used routes in the school environment. Clear benefits from treatment were evident. The assessment and treatment methods employed provide practical and useful ideas for management of this condition in other children. PMID:17178605

    van Houwelingen Hans C

    2009-09-01

    Full Text Available Abstract Background In haplotype-based candidate gene studies a problem is that the genotype data are unphased, which results in haplotype ambiguity. The measure 1 quantifies haplotype predictability from genotype data. It is computed for each individual haplotype, and for a measure of global relative efficiency a minimum value is suggested. Alternatively, we developed methods directly based on the information content of haplotype frequency estimates to obtain global relative efficiency measures: and based on A- and D-optimality, respectively. All three methods are designed for single populations; they can be applied in cases only, controls only or the whole data. Therefore they are not necessarily optimal for haplotype testing in case-control studies. Results A new global relative efficiency measure was derived to maximize power of a simple test statistic that compares haplotype frequencies in cases and controls. Application to real data showed that our proposed method gave a clear and summarizing measure for the case-control study conducted. Additionally this measure might be used for selection of individuals, who have the highest potential for improving power by resolving phase ambiguity. Conclusion Instead of using relative efficiency measure for cases only, controls only or their combined data, we link uncertainty measure to case-control studies directly. Hence, our global efficiency measure might be useful to assess whether data are informative or have enough power for estimation of a specific haplotype risk.

    2003-01-01

    Health technology assessments propose to study the differential impact of health interventions in a complex care system which is characterised by the multitude of individual behaviours and the diverse nature of the institutions involved. Current systems for data collection lend themselves poorly to this rigorous analysis of efficacy of treatments in the actual situations where they are used. Randomised trials endeavour to neutralise any parasitic interference which could compromise testing for a causal relationship between the treatment administered and the result obtained. Their methodology which establishes the term ceteris paribus in the principle of good practice lends itself poorly to an analysis of individual behaviour. Observational studies are start from actual treatment situations to describe them as reliably as possible. By definition, however, these assume that the natural course of events is not deviated by any intervention. The absence of an experimental plan increases the likelihood of bias and makes it more difficult to test for causal relationships. They lend themselves poorly to testing for incremental efficacy. The two instruments to be preferred are decisional analysis and quasi-experimental studies. Decisional analysis help to avoid the problems of external validity associated with randomised clinical trials by associating parameters which are extracted from data obtained from everyday practice. Quasi-experimental studies or pragmatic trials are based on the reality of behaviour of the prescriber and his/her patients; their impact on efficacy, quality of life social costs of the disease and of treatments may be identified under normal conditions of use.

    Full Text Available Most studies of air pollution health effects are based on outdoor ambient exposures, mainly because of the availability of population-based data and the need to support emission control programs. However, there is also a large body of literature on indoor air quality that is more relevant to personal exposures. This assessment attempts to merge these two aspects of pollution-related health effects, emphasizing fine particles. However, the basic concepts are applicable to any pollutant. The objectives are to examine sensitivities of epidemiological studies to the inclusion of personal exposure information and to assess the resulting data requirements. Indoor air pollution results from penetration of polluted outdoor air and from various indoor sources, among which environmental tobacco smoke (ETS is probably the most toxic and pervasive. Adequate data exist on infiltration of outdoor air but less so for indoor sources and effects, all of which have been based on surveys of small samples of individual buildings. Since epidemiology is based on populations, these data must be aggregated using probabilistic methods. Estimates of spatial variation and precision of ambient air quality are also needed. Hypothetical personal exposures in this paper are based on ranges in outdoor air quality, variable infiltration rates, and ranges of indoor source strength. These uncertainties are examined with respect to two types of mortality studies: time series analysis of daily deaths in a given location, and cross-sectional analysis of annual mortality rates among locations. Regressions of simulated mortality on personal exposures, as affected by all of these uncertainties, are used to examine effects on dose-response functions using quasi-Monte Carlo methods. The working hypothesis is that indoor sources are reasonably steady over time and thus applicable only to long-term cross-sectional studies. Uncertainties in exposure attenuate the simulated mortality

    Full Text Available Considering pregnancy and motherhood as periods of increased vulnerability in migrant women, to characterize the healthcare provided to this collective, we sought to identify and understand patterns of satisfaction and demand of maternal and child healthcare, assessing women’s perceptions about its quality. The study followed a qualitative methodology (semi-structured interviews for collecting and analysing data (content analysis and was conducted in Porto, the second largest city of Portugal. Participants were 25 recent immigrant mothers from Eastern European countries, Brazil, Portuguese-speaking African countries and six native Portuguese recent mothers (for comparison, contacted through social associations and institutions. Data suggests that healthcare depends not only on accessibility but especially on social opportunities. Equitable public health action must provide individuals and groups the equal opportunity to meet their needs, which may not be achieved by providing the same standard if care to all.

    The heterogeneous nature of the Mediterranean environment, combined with a wide diversity of economic, social and cultural identities, make this region particularly amenable to integrated research on climate change impacts, vulnerabilities, and adaptive response. Within the framework of the EU FP7 CIRCE project, eleven case-study locations were selected to reflect three generic environments (urban, rural and coastal), to quantify current and future climate change and to assess the potential consequences to human communities and ecosystems at the regional to local scale. The case studies (Athens, Beirut, Alexandria, Tuscany, Apulia, Tel Hadya, Judean Foothills, Gulf of Valencia, Gulf of Oran, Gulf of Gabes, West Nile Delta) were chosen to reflect the east-west and north-south contrasts across the Mediterranean, using common selection criteria. A rigorous common framework, referred to as the CIRCE Case studies Integrating Framework was developed to facilitate a structured and systematic basis for identifying and selecting indicators. Within this framework, climate dynamics is viewed as a key driver of changes in social and biogeophysical systems and is modulated by the inherent dynamics of these systems. The top-down, indicator-based approach was complemented by a bottom-up approach involving local and regional stakeholders. A participatory level of involvement was aimed for, with stakeholder dialogue on an informal basis throughout the project, culminating in a series of more formal regional stakeholder workshops. Identification and construction of physical and socio-economic indicators was the most challenging and time-consuming aspect of the case-study work. A detailed set of selection criteria was defined and the process of reviewing and refining indicators was iterative. Nonetheless, a number of data and methodological challenges were encountered. Despite these issues, indicator linkages diagrams provided a useful preparatory stage for structuring the integrated

    2004-11-01

    The objective of this report is to document scaling studies and conceptual designs for flow and heat transfer experiments intended to assess CFD codes and their turbulence models proposed for application to prismatic NGNP concepts. The general approach of the project is to develop new benchmark experiments for assessment in parallel with CFD and coupled CFD/systems code calculations for the same geometry. Two aspects of the complex flow in an NGNP are being addressed: (1) flow and thermal mixing in the lower plenum ("hot streaking" issue) and (2) turbulence and resulting temperature distributions in reactor cooling channels ("hot channel" issue). Current prismatic NGNP concepts are being examined to identify their proposed flow conditions and geometries over the range from normal operation to decay heat removal in a pressurized cooldown. Approximate analyses have been applied to determine key non-dimensional parameters and their magnitudes over this operating range. For normal operation, the flow in the coolant channels can be considered to be dominant turbulent forced convection with slight transverse property variation. In a pressurized cooldown (LOFA) simulation, the flow quickly becomes laminar with some possible buoyancy influences. The flow in the lower plenum can locally be considered to be a situation of multiple hot jets into a confined crossflow -- with obstructions. Flow is expected to be turbulent with momentumdominated turbulent jets entering; buoyancy influences are estimated to be negligible in normal full power operation. Experiments are needed for the combined features of the lower plenum flows. Missing from the typical jet experiments available are interactions with nearby circular posts and with vertical posts in the vicinity of vertical walls - with near stagnant surroundings at one extreme and significant crossflow at the other. Two types of heat transfer experiments are being considered. One addresses the "hot channel" problem, if necessary

  14. Valdez air health study - Exposure monitoring and risk assessment

    International Nuclear Information System (INIS)

    In Valdez, Alaska there is concern about exposure of the public to benzene and other light hydrocarbons emitted during the loading of tankers from the Trans-Alaska Pipeline. As part of an overall risk assessment, the Valdez Air Health Study, a personal, indoor and outdoor air sampling program patterned after EPA's TEMA Study was designed and carried out. A unique feature of the study is that, during sampling periods, SF6 tracer was released at the terminal site to represent terminal hydrocarbon emissions to provide a basis for directly quantitating any contribution of terminal emissions to personal exposure. Sixty citizens at Valdez were selected to wear vests containing sampling equipment for 24-hour periods summer and winter. At the homes of 30 of the participants simultaneous indoor and outdoor samples for hydrocarbons and tracer were collected during the period that each participant collected personal air samples. The paper reviews the design of the program, details of the procedures used, results of the August, 1990 program and preliminary results from the February-March, 1991 program

  15. A field study comparing two methods of transportation risk assessment

    International Nuclear Information System (INIS)

    RADTRAN 4 is a computer code used for; assessing risks associated with the transportation of nuclear materials. The code employs the common modeling practice of using default values for input variables to simplify the modeling of complex scenarios, thus producing conservative final risk determinations. To better address local public concerns it is of interest to quantify the introduced conservatism by taking a site-specific approach to radiation risk assessment. With RISKIND, incident-free and accident condition doses were calculated for two suburban population groups using both default input parameters; and site-specific values to describe population demographics of regions in Pocatello, Idaho, along the I-15 corridor. The use of site-specific parameters resulted in incident-free doses ranging from the same order of magnitude to one order of magnitude less than the doses calculated with default input parameters. Correcting accident condition doses for the age distribution of the populations and employing site-specific weather data resulted in doses 1.1 times lower than estimated using default input parameters. Dose-risks calculated with RISKIND for the two population groups using site-specific data were of the same order of magnitude as the risk calculated using RADTRAN 4 for the suburban population described in DOE/EIS-0203-D. This study revealed in one specific application that use of default and site-specific parameters resulted in comparable dose estimates. If this tendency were to hold generally true over other environments and model variables, then risk assessors might prefer to select codes on the basis of criteria such as (1) the number of variables to select from; (2) ability to calculate consequences directly, and (3) outputs geared to addressing public concerns

    Full Text Available This paper assesses the reality of corporate governance in Jordan. It identifies the framework of corporate governance, which has here been set into two dimensions – institutionalisations and regulations – and describes the five major principles of corporate governance. The study was carried out by interviews with key employees and the review of related laws and selected annual reports. The study found (1 basic shareholder rights were honoured in decision-making, except for large decisions such as major asset sales; (2 shareholders were not treated equitably in practice, although controllers sometimes took action and prohibited insider trading; (3 the role and rights of stakeholders in corporate governance were respected, and stakeholders had a number of legal protections, which were largely covered in Jordan's Company Law; (4 disclosure and transparency were observed to a large extent, although limited to quantity rather than quality, because Jordan has fully adopted IFRS and ISA and (5 boards largely fulfilled their responsibilities, as these are extensively defined by law and regulation.

  17. Recent case studies and advancements in probabilistic risk assessment

    International Nuclear Information System (INIS)

    During the period from 1977 to 1984, Pickard, Lowe and Garrick, Inc., had the lead in preparing several full scope probabilistic risk assessments for electric utilities. Five of those studies are discussed from the point of view of advancements and lessons learned. The objective and trend of these studies is toward utilization of the risk models by the plant owners as risk management tools. Advancements that have been made are in presentation ad documentation of the PRAs, generation of more understandable plant level information, and improvements in methodology to facilitate technology transfer. Specific areas of advancement are in the treatment of such issues as dependent failures, human interaction, and the uncertainty in the source term. Lessons learned cover a wide spectrum and include the importance of plant specific models for meaningful risk management, the role of external events in risk, the sensitivity of contributors to choice of risk index, and the very important finding that the public risk is extremely small. The future direction of PRA is to establish less dependence on experts for in-plant application. Computerizing the PRAs such that they can be accessed on line and interactively is the key

    Highlights: •Solid solubity of Gd in (Mg) experimentally studied. •Consistent thermodynamic calculation of Mg–Gd phase diagram developed. •Vapor pressure and enthalpy of formation data analyzed by Calphad method. •Three error sources identified in earlier approximate enthalpy derivation. •Claimed systematic trends in enthalpies of formation disputed. -- Abstract: The solid solubility of Gd in (Mg) is studied experimentally using microstructure, chemical and EDX analysis on permanent mould chill cast samples which were annealed for 1–14 days at 300–550 °C. Based on those key data and all the critically assessed experimental phase equilibrium and thermodynamic data of the Mg–Gd system two Calphad-type thermodynamic descriptions are developed. This provides calculated phase diagrams, and an inherent inconsistency between the vapor pressure data and the Mg-rich phase diagram is indicated. A previous misperception of “experimental” enthalpy of formation data of binary Gd{sub x}Mg{sub y} intermetallic compounds is also revealed. The assumption of systematic trends in these key thermodynamic data for the series of rare earth elements R = (La, Ce, Pr, Nd, Sm, Gd) is scrutinized.

    Full Text Available Abstract Background Lengthy questionnaires reduce data quality and impose a burden on respondents. Previous researchers proposed that a single item ("My future seems dark to me" and a 4-item component of the Beck's Hopelessness Scale (BHS can summarise most of the information the BHS provides. There is no clear indication of what BHS cutoff values are useful in identifying people with suicide tendency. Methods In a population-based study of Chinese people aged between 15 and 59 in Hong Kong, the Chinese version of the BHS and the Centre for Epidemiologic Studies – Depression scale were administered by trained interviewers and suicidal ideation and suicidal attempts were self-reported. Receiver operating characteristics curve analysis and regression analysis were used to compare the performance of the BHS and its components in identifying people with suicidality and depression. Smoothed level of suicidal tendency was assessed in relation to scores on the BHS and its component to identify thresholds. Results It is found that the 4-item component and, to a lesser extent, the single item of the BHS perform in ways similar to the BHS. There are non-linear relationship between suicidality and scores on the BHS and the 4-item component; cutoff values identified accordingly have sensitivity and specificity of about 65%. Conclusion The 4-item component is a useful alternative to the BHS. Shortening of psycho-social measurement scales should be considered in order to reduce burden on patients or respondents and to improve response rate.

    In this paper, we discuss the advantages and drawbacks of the most classical approaches used in lichenometry. In particular, we perform a detailed comparison among methods based on the statistical analysis of either the largest lichen diameters recorded on geomorphic features or the frequency of all lichens. To assess the performance of each method, a careful comparison design with well-defined criteria is proposed and applied to two distinct data sets. First, we study 350 tombstones. This represents an ideal test bed because tombstone dates are known and, therefore, the quality of the estimated lichen growth curve can be easily tested for the different techniques. Secondly, 37 moraines from two tropical glaciers are investigated. This analysis corresponds to our real case study. For both data sets, we apply our list of criteria that reflects precision, error measurements and their theoretical foundations when proposing estimated ages and their associated confidence intervals. From this comparison, it clearly appears that two methods, the mean of the n largest lichen diameters and the recent Bayesian method based on extreme value theory, offer the most reliable estimates of moraine and tombstones dates. Concerning the spread of the error, the latter approach provides the smallest uncertainty and it is the only one that takes advantage of the statistical nature of the observations by fitting an extreme value distribution to the largest diameters.

  1. Bridging probabilistic safety assessment studies with information Management System

    International Nuclear Information System (INIS)

    Probabilistic Safety Assessment (PSA) is a critical business often known in conjunction with either new build or life extension of nuclear power plant. However, it is not so often referred to the operation phase of the plant, although it could bring a lot of long term benefits to the operator. The purpose of this paper is to discuss the potential contribution of PSA with day to day operation in bridging the deficiencies and specific failures characteristics of critical Structure System and Component (SSC) with the results of PSA studies. From and Information System prospective, the use of Information Management system (IMS) -also known as EAM solution -widely used by the majority of nuclear operators- is the potential vehicle to bridge the 2 worlds of PSA and daily operation. Most EAM solution get reliability management functionalities which are not really integrated with PSA tools and data and thus cannot provide the anticipated benefits of addressing typical aging phenomena beyond the only predictive models used by the PSA studies. The paper will also discuss potential integration scenario between PSA tools and EAM solutions. (authors)

    Full Text Available Problem statement: Thermal comfort has a great influence on the productivity and satisfaction of indoor building occupants. The exposure to excessive heat during work may cause discomfort and contributed to low productivity among workers. Malaysia known with its hot and humid weather where in most of the survey study published indicated that workers in Malaysia automotive industries had exposed to excessive temperature while working. The study investigated the thermal comfort level experienced by workers at Malaysian automotive industry. Approach: The study had been conducted at one automotive parts assembly factory in Malaysia. The human subjects for the study constitute operators at tire receiving section of the factory. The environment examined was the relative humidity (%, WBGT, air temperature and radiant temperature (°C of the surrounding workstation area. The environmental factors were measured using Babuc apparatus, which is capable to measure simultaneously those mentioned environmental factors. The time series data of fluctuating level of factors were plotted to identify the significant changes of factors. Then thermal comfort of the workers was assessed by using ASHRAE thermal sensation scale by using Predicted Mean Vote (PMV. Further Predicted Percentage Dissatisfied (PPD was used to estimate the thermal comfort satisfaction of the occupant. Finally the PPD versus PMV were plotted to present the thermal comfort scenario of workers involved in related workstation. Results: The trend of relative humidity curve from the graph also indicated the increasing level of discomfort. The radiant temperature observed seems consistent during the study while there was decreasing of WBGT start from afternoon due to the rain. The study revealed that the PPD value of 54% of the workers population at the workstation are likely to be satisfied with thermal comfort at this station while the PMV index from ASHRAE indicated the value 1

    Aims Recent research has suggested that for some individuals, educational studying may become compulsive and excessive and lead to ‘study addiction’. The present study conceptualized and assessed study addiction within the framework of workaholism, defining it as compulsive over-involvement in studying that interferes with functioning in other domains and that is detrimental for individuals and/or their environment. Methods The Bergen Study Addiction Scale (BStAS) was tested – reflecting seven core addiction symptoms (salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems) – related to studying. The scale was administered via a cross-sectional survey distributed to Norwegian (n = 218) and Polish (n = 993) students with additional questions concerning demographic variables, study-related variables, health, and personality. Results A one-factor solution had acceptable fit with the data in both samples and the scale demonstrated good reliability. Scores on BStAS converged with scores on learning engagement. Study addiction (BStAS) was significantly related to specific aspects of studying (longer learning time, lower academic performance), personality traits (higher neuroticism and conscientiousness, lower extroversion), and negative health-related factors (impaired general health, decreased quality of life and sleep quality, higher perceived stress). Conclusions It is concluded that BStAS has good psychometric properties, making it a promising tool in the assessment of study addiction. Study addiction is related in predictable ways to personality and health variables, as predicted from contemporary workaholism theory and research. PMID:26014668

    Full Text Available Abstract Background Joint replacement is an effective intervention for people with advanced arthritis, although there is an important minority of patients who do not improve post-operatively. There is a need for robust evidence on outcomes after surgery, but there are a number of measures that assess function after joint replacement, many of which lack any clear theoretical basis. The World Health Organisation has introduced the International Classification of Functioning, Disability and Health (ICF, which divides function into three separate domains: Impairment, activity limitations and participation restrictions. The aim of this study is to compare the properties and responsiveness of a selection of commonly used outcome tools that assess function, examine how well they relate to the ICF concepts, and to explore the changes in the measures over time. Methods/design Two hundred and sixty three patients listed for lower limb joint replacement at an elective orthopaedic centre have been recruited into this study. Participants attend the hospital for a research appointment prior to surgery and then at 3-months and 1-year after surgery. At each assessment time, function is assessed using a range of measures. Self-report function is assessed using the WOMAC, Aberdeen Impairment, Activity Limitation and Participation Restriction Measure, SF-12 and Measure Yourself Medical Outcome Profile 2. Clinician-administered measures of function include the American Knee Society Score for knee patients and the Harris Hip Score for hip patients. Performance tests include the timed 20-metre walk, timed get up and go, sit-to-stand-to-sit, step tests and single stance balance test. During the performance tests, participants wear an inertial sensor and data from motion analysis are collected. Statistical analysis will include exploring the relationship between measures describing the same ICF concepts, assessing responsiveness, and studying changes in measures over

  14. Assessment of existing studies of wind loading on solar collectors

    Energy Technology Data Exchange (ETDEWEB)

    Murphy, L. M.

    1981-02-01

    In developing solar collectors, wind loading is the major structural design consideration. Wind loading investigations have focused on establishing safe bounds for steady state loading and verifying rational but initial and conservative design approaches for the various solar collector concepts. As such, the effort has been very successful, and has contributed greatly to both the recognition and qualitative understanding of many of the physical phenomena involved. Loading coefficients corresponding to mean wind velocities have been derived in these prior studies to measure the expected structural loading on the various solar collectors. Current design and testing procedures for wind loading are discussed. The test results corresponding to numerous wind tests on heliostats, parabolic troughs, parabolic dishes, and field mounted photovoltaic arrays are discussed and the applicability of the findings across the various technologies is assessed. One of the most significant consistencies in the data from all the technologies is the apparent benefit provided by fences and field shielding. Taken in toto, these data show that load reductions of three or possibly more seem feasible, though a more thorough understanding of the phenomena involved must be attained before this benefit can be realized. It is recommended that the required understanding be developed to take advantage of this benefit and that field tests be conducted to correlate with both analyses and tests.

  15. Comparative assessment study of aboveground soft x-ray technology

    International Nuclear Information System (INIS)

    The soft x-ray regime accessible at the laboratory nominally extends from photon energies of 10 eV to 10 keV. The technology relies on capacitor-based, short-pulse energy storage devices to generate a high-energy-density plasma 1 cc in volume and lasting about 10 ns. The hot plasma is created either by conversion of short-pulse electrical energy into light ions that heat the plasma or into a magnetically-driven imploding plasma. Applications of these intense soft x-rays include evaluation of their interaction with materials, as an energy source for weapons effects, as a source for ICF experiments, and as a source for weapons physics experiments. Because of management's interest in encouraging the development of new applications to this technology, they did a year-long comparative assessment study that involved surveying scientists engaged in such research. The literature is filled with examples of benchmarking in the manufacturing and service industries; however, the authors found only one documented case where scientific research had been benchmarked. The experience in benchmarking an area of scientific research and some of the findings are described in this paper

    Full Text Available Background: The major contaminants usually encountered in milk and milk products include pesticide residues, heavy metals, and aflatoxin M1 (AFM1. Primarily, milk get contaminated before milching, from the cattle feed, from sources/materials used during the processing of milk as well as improper handling of the milk during the pre- and postprocessing period. Objective: The purpose of this study was to evaluate the effect of household practices on milk contaminants. Materials and Methods: Samples of pasteurized as well as unpasteurized milk (Vendor′s milk were analyzed for AFM1, pesticide residues, and heavy metals. Simulating the household practices, the impact of boiling on these contaminants was assessed. Results: The contaminant Aflatoxin M1 (AFM1 was detected at a concentration ranging from 0.071-0.075 ppb in unpasteurized as well as pasteurized milk samples analyzed during the course of study. Moreover, boiling had no impact on the quantity of AFM1 present in the milk. Pesticides and heavy metal contents were found to be within acceptable limits in all the milk samples tested. Conclusion: Mycotoxins especially aflatoxins in cattle feed and their consequential presence in milk and milk products is a serious concern world over as they are reported carcinogens. These fungal toxins are resistant to high temperatures and may lead to various health hazards. Preventive steps must be taken at each stage to ensure good quality of milk and milk products free from these contaminants. Awareness programs and education for the dairy farmers and milk processors may be helpful in this regard.

    China's legislature on the environmental impact assessments contains related provisions on public participation as an important element of institutions in this field. So far, however, the stipulation remains at the level of a plain statement of principle both substantially and procedurally. The newly enacted Law on the Assessment of the Environment Impact has seen great progress in provisions for public participation if compared with similar statutes enacted in the past legislation. However, there is a gap in the procedures,

  2. PARALLEL MODELS OF ASSESSMENT: INFANT MENTAL HEALTH AND THERAPEUTIC ASSESSMENT MODELS INTERSECT THROUGH EARLY CHILDHOOD CASE STUDIES.

    Science.gov (United States)

    Gart, Natalie; Zamora, Irina; Williams, Marian E

    2016-07-01

    Therapeutic Assessment (TA; S.E. Finn & M.E. Tonsager, 1997; J.D. Smith, 2010) is a collaborative, semistructured model that encourages self-discovery and meaning-making through the use of assessment as an intervention approach. This model shares core strategies with infant mental health assessment, including close collaboration with parents and caregivers, active participation of the family, a focus on developing new family stories and increasing parents' understanding of their child, and reducing isolation and increasing hope through the assessment process. The intersection of these two theoretical approaches is explored, using case studies of three infants/young children and their families to illustrate the application of TA to infant mental health. The case of an 18-month-old girl whose parents fear that she has bipolar disorder illustrates the core principles of the TA model, highlighting the use of assessment intervention sessions and the clinical approach to preparing assessment feedback. The second case follows an infant with a rare genetic syndrome from ages 2 to 24 months, focusing on the assessor-parent relationship and the importance of a developmental perspective. Finally, assessment of a 3-year-old boy illustrates the development and use of a fable as a tool to provide feedback to a young child about assessment findings and recommendations. PMID:27333488

  5. Hydrodynamic and Ecological Assessment of Nearshore Restoration: A Modeling Study

    International Nuclear Information System (INIS)

    Along the Pacific Northwest coast, much of the estuarine habitat has been diked over the last century for agricultural land use, residential and commercial development, and transportation corridors. As a result, many of the ecological processes and functions have been disrupted. To protect coastal habitats that are vital to aquatic species, many restoration projects are currently underway to restore the estuarine and coastal ecosystems through dike breaches, setbacks, and removals. Information on physical processes and hydrodynamic conditions are critical for the assessment of the success of restoration actions. Restoration of a 160- acre property at the mouth of the Stillaguamish River in Puget Sound has been proposed. The goal is to restore native tidal habitats and estuary-scale ecological processes by removing the dike. In this study, a three-dimensional hydrodynamic model was developed for the Stillaguamish River estuary to simulate estuarine processes. The model was calibrated to observed tide, current, and salinity data for existing conditions and applied to simulate the hydrodynamic responses to two restoration alternatives. Responses were evaluated at the scale of the restoration footprint. Model data was combined with biophysical data to predict habitat responses at the site. Results showed that the proposed dike removal would result in desired tidal flushing and conditions that would support four habitat types on the restoration footprint. At the estuary scale, restoration would substantially increase the proportion of area flushed with freshwater (< 5 ppt) at flood tide. Potential implications of predicted changes in salinity and flow dynamics are discussed relative to the distribution of tidal marsh habitat.

    2015-10-01

    Participatory GIS (PGIS) has been prescribed by scholars who sought to find a means to enable more equitable access to GIS data, diversifying the types of knowledge captured by a GIS and re-engineering GIS software. The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few. Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product. Notably, this a reflective exercise on one case study, but the methodologies used in this study have been replicated in many others undertaken by Community Based Organisations as well as Non-Governmental Organisations. Therefore the findings are relevant to such projects.

    2014-03-01

    Full Text Available Forest biodiversity is an important part of biodiversity. There is an essential significance of studying forest biodiversity assessment for promoting the conservation of biodiversity and enhancing biodiversity management in China. This study collected forest biodiversity habitat area, output value of forestry and so on forest biodiversity assessment-related data from 2001 to 2010 in China and using optimal control methods in cybernetics to establish value assessment model of forest biodiversity based on the data of habitat area, as well as calculated the optimal price for forest biodiversity assessment. The result showed that forest biodiversity habitat assessment of the optimal price is 9,970 RMB Yuan/ha and there is a dynamic model for forest biodiversity assessment. Finally, the study suggested that studies of forest biodiversity assessment in China, in particular, studying of valuation of forest biodiversity should consider using shadow price and the social, economic and other factors should be taken into account

  14. Assessment Study of Small Space Debris Removal by Laser Satellites

    Science.gov (United States)

    Choi, Sang H.; Papa, Richard S.

    2011-01-01

    Space debris in Earth orbit poses significant danger to satellites, humans in space, and future space exploration activities. In particular, the increasing number of unidentifiable objects, smaller than 10 cm, presents a serious hazard. Numerous technologies have been studied for removing unwanted objects in space. Our approach uses a short wavelength laser stationed in orbit to vaporize these small objects. This paper discusses the power requirements for space debris removal using lasers. A short wavelength laser pumped directly or indirectly by solar energy can scan, identify, position, and illuminate the target, which will then be vaporized or slow down the orbital speed of debris by laser detonation until it re-enters the atmosphere. The laser-induced plasma plume has a dispersive motion of approximately 105 m/sec with a Lambertian profile in the direction of the incoming beam [1-2]. The resulting fast ejecting jet plume of vaporized material should prevent matter recombination and condensation. If it allows any condensation of vaporized material, the size of condensed material will be no more than a nanoscale level [3]. Lasers for this purpose can be indirectly pumped by power from an array of solar cells or directly pumped by the solar spectrum [4]. The energy required for vaporization and ionization of a 10 cm cube ( 2700 gm) of aluminum is 87,160 kJ. To remove this amount of aluminum in 3 minutes requires a continuous laser beam power of at least 5.38 MW under the consideration of 9% laser absorption by aluminum [5] and 5% laser pumping efficiency. The power needed for pumping 5.38 MW laser is approximately 108 MW, which can be obtained from a large solar array with 40% efficiency solar cells and a minimal area of 450 meters by 450 meters. This solar array would collect approximately 108 MW. The power required for system operation and maneuvering can be obtained by increasing solar panel size. This feasibility assessment covers roughly the power requirement

    In the reliability-risk assessment, the second order reliability index (βⅡ) method and the Conditional ExpectationMonte Carlo (CEMC) simulation are interrelated as a new Level Ⅲ approach for the analysis of the safety level of theDalaman yacht harbor vertical wall breakwater in Turkey. The missing wave data of the Dalaman measurement station arehindcasted by use of muhi-layer feed-forward neural networks with the steepest descent and conjugate gradient algorithms.The structural failure probabilities of sliding and overturning failure modes are forecasted by approximation of the failure sur-face with a second-degree polynomial of an equal curvature at the design point. In the new approach, for each randomlygenerated load and tide combination, the joint failure probability reflects both the occurrence probability of loading conditionand the structural failure risk at the limit state. The approach can be applied to risk assessment of vertical breakwaters inshort CPU durations of portable computers.

    2014-01-01

    Patients with Parkinson's disease (PD) can exhibit a reduction of spontaneous facial expression, designated as "facial masking," a symptom in which facial muscles become rigid. To improve clinical assessment of facial expressivity of PD, this work attempts to quantify the dynamic facial expressivity (facial activity) of PD by automatically recognizing facial action units (AUs) and estimating their intensity. Spontaneous facial expressivity was assessed by comparing 7 PD patients with 8 control participants. To voluntarily produce spontaneous facial expressions that resemble those typically triggered by emotions, six emotions (amusement, sadness, anger, disgust, surprise, and fear) were elicited using movie clips. During the movie clips, physiological signals (facial electromyography (EMG) and electrocardiogram (ECG)) and frontal face video of the participants were recorded. The participants were asked to report on their emotional states throughout the experiment. We first examined the effectiveness of the emotion manipulation by evaluating the participant's self-reports. Disgust-induced emotions were significantly higher than the other emotions. Thus we focused on the analysis of the recorded data during watching disgust movie clips. The proposed facial expressivity assessment approach captured differences in facial expressivity between PD patients and controls. Also differences between PD patients with different progression of Parkinson's disease have been observed. PMID:25478003

    2016-08-01

    The goal of the present study was to compare etiologically and clinically relevant correlates of lifetime AUD (e.g., alcohol consumption, personality traits, psychiatric disorders) based on a single assessment compared to a cumulative, prospective assessment of lifetime AUD. Data were drawn from the Alcohol, Health and Behavior (AHB; baseline N=489) study, which consisted of a prospective cohort of college students assessed seven times over a 16-year period ([M(SD) age at baseline=18.56 (.97)] and [M(SD) age at final assessment=34.33 (.82)]). The participants were assessed using the Diagnostic Interview Schedule (DIS) for DSM-III at Waves 1-7 and for DSM-IV at Waves 6-7. A single assessment and cumulative assessments of DSM-III lifetime AUD at Wave 6 (M[SD] age=28.98 [1.03]) were used to predict past-year alcohol related variables (e.g., alcohol consumption, drinking motives, drinking expectancies), personality variables, general functioning, lifetime substance use, and lifetime psychiatric disorders at Wave 7. Significantly larger correlations were found between the cumulative assessment and eight of the 25 etiologically relevant correlates of AUD compared to the single assessment. Further, significant incremental validity of cumulative assessment over single, retrospective assessment was observed for 16 of the 25 covariates. Overall, this study provides further support for the value of using prospective data with multiple assessments when determining lifetime history of disorder. PMID:27082748

  20. Tissue quality assessment using a novel direct elasticity assessment device (the E-finger: a cadaveric study of prostatectomy dissection.

    Full Text Available Minimally invasive radical prostatectomy (RP (robotic and laparoscopic, have brought improvements in the outcomes of RP due to improved views and increased degrees of freedom of surgical devices. Robotic and laparoscopic surgeries do not incorporate haptic feedback, which may result in complications secondary to inadequate tissue dissection (causing positive surgical margins, rhabdosphincter damage, etc. We developed a micro-engineered device (6 mm2 sized [E-finger] capable of quantitative elasticity assessment, with amplitude ratio, mean ratio and phase lag representing this. The aim was to assess the utility of the device in differentiating peri-prostatic tissue types in order to guide prostate dissection.Two embalmed and 2 fresh frozen cadavers were used in the study. Baseline elasticity values were assessed in bladder, prostate and rhabdosphincter of pre-dissected embalmed cadavers using the micro-engineered device. A measurement grid was created to span from the bladder, across the prostate and onto the rhabdosphincter of fresh frozen cadavers to enable a systematic quantitative elasticity assessment of the entire area by 2 independent assessors. Tissue was sectioned along each row of elasticity measurement points, and stained with haematoxylin and eosin (H&E.

    The life cycle of technology is one of the most important indexes to weigh up the risk of the investment to neo-tech. There are so many uncertainties because it is conditioned by a lot of factors, we can not make a rational forecasting by traditional assessment method. So this paper gives a conprehensive consideration to the factors that influence production and makes some modification to production function, and establishes the life cycle of technology assessmet model by the method of fuzzy mathematics. So it quantifies the risk of investment. We can take it as one foundational index for the decision making of the investment.

    Increasing residential insulation can decrease energy consumption and provide public health benefits, given changes in emissions from fuel combustion, but also has cost implications and ancillary risks and benefits. Risk assessment or life cycle assessment can be used to calculate the net impacts and determine whether more stringent energy codes or other conservation policies would be warranted, but few analyses have combined the critical elements of both methodologies In this article, we present the first portion of a combined analysis, with the goal of estimating the net public health impacts of increasing residential insulation for new housing from current practice to the latest International Energy Conservation Code (IECC 2000). We model state-by-state residential energy savings and evaluate particulate matter less than 2.5 microm in diameter (PM2.5), NOx, and SO2 emission reductions. We use past dispersion modeling results to estimate reductions in exposure, and we apply concentration-response functions for premature mortality and selected morbidity outcomes using current epidemiological knowledge of effects of PM2.5 (primary and secondary). We find that an insulation policy shift would save 3 x 10(14) British thermal units or BTU (3 x 10(17) J) over a 10-year period, resulting in reduced emissions of 1,000 tons of PM2.5, 30,000 tons of NOx, and 40,000 tons of SO2. These emission reductions yield an estimated 60 fewer fatalities during this period, with the geographic distribution of health benefits differing from the distribution of energy savings because of differences in energy sources, population patterns, and meteorology. We discuss the methodology to be used to integrate life cycle calculations, which can ultimately yield estimates that can be compared with costs to determine the influence of external costs on benefit-cost calculations.

  12. Accuracy of deconvolution algorithms assessed by simulation studies: concise communication

    International Nuclear Information System (INIS)

    Deconvolution has been used to correct first-pass radionuclide angiocardiography for the time course of the delivery of radiopharmaceutical into the cardiopulmonary system. The extreme sensitivity of deconvolution to random errors in the data may account for some of the problems encountered in practice. We implemented several deconvolution algorithms that were suitable for use with the unimodal and multimodal superior vena caval and pulmonary curves found in left-to-right shunt quantification. The sensitivity of the algorithms to random errors was assessed using mathematical test problems degraded with pseudorandom noise. An algorithm that constrained the deconvolved pulmonary curve to be expressable as the non-negative sum of a set of lagged normal curves was found to have the smallest maximum error on the curves tested. Comparison with results from a previously published test problem indicated an error reduction of greater than 50% over previously used algorithms. Use of this algorithm may permit more accurate deconvolution of pulmonary time-activity curves and thereby improve shunt quantification

  14. Case study of ecological risk assessment at an Alaska airport

    International Nuclear Information System (INIS)

    An ecological risk assessment was conducted for 10 sites at a remote location that has unique biological resources. Chemicals of concern included petroleum, metals, polychlorinated biphenyls, and dioxins and furans. Risks to 23 species of mammals and birds were evaluated by using toxicity reference values and a hazard quotient approach analogous to the US Environmental Protection Agency's (USEPA's) approach for evaluating noncarcinogenic human health effects. Risks to fish and aquatic invertebrates were evaluated using risk-based concentrations for water analogous to the USEPA's water quality criteria. Risks to plants were evaluated using risk-based concentrations for soil. Toxicity reference values and risk-based concentrations were developed by applying uncertainty factors to the highest quality toxicity data available in the literature. Intake rates for wildlife were obtained from the USEPA's wildlife exposure factors handbook, or were estimated using allometric equations. The sizes of wildlife home ranges were compared with the size of each site to determine species- and site-specific exposure frequencies. Indicator chemicals were selected to represent the chemical and toxicological characteristics of petroleum fractions. The species most often at risk were found to be fish and aquatic invertebrates, as well as small-bodied, ground-dwelling or ground-feeding wildlife

  16. Assessment of human decision reliability - a case study

    International Nuclear Information System (INIS)

    In his discussion of this case study, the author indicates that human beings are not merely machines who use rules. Thus, more focus needs to be put on studying decision making situations and their contexts. Decision theory (both normative and descriptive) and contextual psychological approaches may offer tools to cope with operator decision making. Further an ideal decision space needs to be defined for operators. The case study specifically addressed a loss of feedwater scenario and the various operator decisions that were involved in that scenario. It was concluded from this particular study that there are significant differences in the crew decision behaviours that are not explained by process variables. Through use of evidence from simulator tests with expert judgement, an approach to estimate probabilities has been developed. The modelling approach presented in this discussion is an extension of current HRA paradigms, but a natural one since all human beings make decisions

    Measurement of dangerous, harmful and annoying factors in the working environment are used to assess occupational risk. Surveys on workers' subjective perception of risk are used, too. This study aimed to compare subjective assessment of work-related factors with their objective measurements and a national database on occupational risk. Spearman's correlation analysis, stepwise regression analysis and structural modelling were used to determine the relationship between subjective and objective risk assessment and to acquire knowledge about the role of psychosocial job characteristics as predictors of subjective assessment. Subjective assessment of hazards was related not only to their objective measurements but also to psychosocial job characteristics, workers' individual characteristics and work load. Even though subjective and objective assessments of hazard are strongly related, they are distinct phenomena. Hence, risk assessment should be carried out with both objective and subjective methods.

    Background: The Early Detection Research Network (EDRN), NCI funded and investigator driven, has the mission to evaluate biomarkers for their clinical utilities in cancer risk prediction, diagnosis, early detection, and prognosis. Abundant cancer biomarkers reported in literature yet few are used in clinics. Therefore, the emphasis of the EDRN is biomarker validation. Although schema for a phased approach to development exists and guidelines are available for study reporting, a coherent and comprehensive set of guideline for a definitive biomarker validation study design have not been delineated.Methods: We proposed PROBE study design, Prospective specimen collec-tion and Retrospective Blinded Evaluation, for pivotal definitive evaluation of the accuracy of a classification biomarker. A detailed formulation of all aspects of the design is provided. Four tables itemize aspects that relate to (i) the Clinical Context; (ii) Performance Criteria; (iii) the Biomarker test; and (iv) Study power and termination. Alternative designs and strategies were contrasted to illustrate the merit of PROBE design.Results: The ideas are applied to studies of biomarkers the intended use of which is for disease diagnosis, screening, or prognosis. Two EDRN valida-tion studies (breast cancer and prostate cancer) were used as examples to elucidate PROBE design.Conclusion: Common biases that pervade the biomarker research literaturewould be eliminated if these rigorous standards were followed closely. We urge the adoption of the design as standard of practice for pivotal evaluation of the classification accuracy ofbiomarkers.

    Introduction Minimally invasive radical prostatectomy (RP) (robotic and laparoscopic), have brought improvements in the outcomes of RP due to improved views and increased degrees of freedom of surgical devices. Robotic and laparoscopic surgeries do not incorporate haptic feedback, which may result in complications secondary to inadequate tissue dissection (causing positive surgical margins, rhabdosphincter damage, etc). We developed a micro-engineered device (6 mm2 sized) [E-finger]) capable of quantitative elasticity assessment, with amplitude ratio, mean ratio and phase lag representing this. The aim was to assess the utility of the device in differentiating peri-prostatic tissue types in order to guide prostate dissection. Material and Methods Two embalmed and 2 fresh frozen cadavers were used in the study. Baseline elasticity values were assessed in bladder, prostate and rhabdosphincter of pre-dissected embalmed cadavers using the micro-engineered device. A measurement grid was created to span from the bladder, across the prostate and onto the rhabdosphincter of fresh frozen cadavers to enable a systematic quantitative elasticity assessment of the entire area by 2 independent assessors. Tissue was sectioned along each row of elasticity measurement points, and stained with haematoxylin and eosin (H&E). Image analysis was performed with Image Pro Premier to determine the histology at each measurement point. Results Statistically significant differences in elasticity were identified between bladder, prostate and sphincter in both embalmed and fresh frozen cadavers (p = <0.001). Intra-class correlation (ICC) reliability tests showed good reliability (average ICC = 0.851). Sensitivity and specificity for tissue identification was 77% and 70% respectively to a resolution of 6 mm2. Conclusions This cadaveric study has evaluated the ability of our elasticity assessment device to differentiate bladder, prostate and rhabdosphincter to a resolution of 6 mm2. The

  4. An approach for integrating toxicogenomic data in risk assessment: The dibutyl phthalate case study

    International Nuclear Information System (INIS)

    An approach for evaluating and integrating genomic data in chemical risk assessment was developed based on the lessons learned from performing a case study for the chemical dibutyl phthalate. A case study prototype approach was first developed in accordance with EPA guidance and recommendations of the scientific community. Dibutyl phthalate (DBP) was selected for the case study exercise. The scoping phase of the dibutyl phthalate case study was conducted by considering the available DBP genomic data, taken together with the entire data set, for whether they could inform various risk assessment aspects, such as toxicodynamics, toxicokinetics, and dose–response. A description of weighing the available dibutyl phthalate data set for utility in risk assessment provides an example for considering genomic data for future chemical assessments. As a result of conducting the scoping process, two questions—Do the DBP toxicogenomic data inform 1) the mechanisms or modes of action?, and 2) the interspecies differences in toxicodynamics?—were selected to focus the case study exercise. Principles of the general approach include considering the genomics data in conjunction with all other data to determine their ability to inform the various qualitative and/or quantitative aspects of risk assessment, and evaluating the relationship between the available genomic and toxicity outcome data with respect to study comparability and phenotypic anchoring. Based on experience from the DBP case study, recommendations and a general approach for integrating genomic data in chemical assessment were developed to advance the broader effort to utilize 21st century data in risk assessment. - Highlights: • Performed DBP case study for integrating genomic data in risk assessment • Present approach for considering genomic data in chemical risk assessment • Present recommendations for use of genomic data in chemical risk assessment

    /Anžela Nikolovska

    2015-11-01

    Full Text Available The paper explores Macedonian primary EFL teachers’ attitudes, beliefs and practices regarding self-assessment of young learners (10-12 year-olds. The study surveyed primary EFL teachers (n=30 who teach English to 5th and 6th graders. The results indicated that vocabulary, grammar and reading were more often the focus of self-assessment tasks than the other areas of language learning. This, along with the finding that the receptive language skills were more frequently self-assessed than the productive skills has been attributed to the impact of the external exam. The most frequently used self-assessment techniques were can-do statements and check-lists. The perceived benefits and challenges of self-assessment have been found to be compatible with the findings of other studies. In spite of their positive attitudes towards learner self-assessment, the teachers expressed awareness of certain problems underlying its implementation as well as uncertainty about how to train learners to self-assess. In line with the conclusions, recommendations have been made regarding the need for greater emphasis on self-assessment of the neglected language areas (speaking and writing, the necessity of using a variety of self-assessment formats and the need for learner training in self-assessment from an early age.

    2011-03-01

    Numerous organizations have published reports in recent years that investigate the ever changing world of electric vehicle (EV) technologies and their potential effects on society. Specifically, projections have been made on greenhouse gas (GHG) emissions associated with these vehicles and how they compare to conventional vehicles or hybrid electric vehicles (HEVs). Similar projections have been made on the volumes of oil that these vehicles can displace by consuming large amounts of grid electricity instead of petroleum-based fuels. Finally, the projected rate that these new vehicle fleets will enter the market varies significantly among organizations. New ideas, technologies, and possibilities are introduced often, and projected values are likely to be refined as industry announcements continue to be made. As a result, over time, a multitude of projections for GHG emissions, oil displacement, and market penetration associated with various EV technologies has resulted in a wide range of possible future outcomes. This leaves the reader with two key questions: (1) Why does such a collective range in projected values exist in these reports? (2) What assumptions have the greatest impact on the outcomes presented in these reports? Since it is impractical for an average reader to review and interpret all the various vehicle technology reports published to date, Sentech Inc. and the Oak Ridge National Laboratory have conducted a comparative study to make these interpretations. The primary objective of this comparative study is to present a snapshot of all major projections made on GHG emissions, oil displacement, or market penetration rates of EV technologies. From the extensive data found in relevant publications, the key assumptions that drive each report's analysis are identified and 'apples-to-apples' comparisons between all major report conclusions are attempted. The general approach that was taken in this comparative study is comprised of six primary

  7. FINAL REPORT ON THE AQUATIC MERCURY ASSESSMENT STUDY

    Energy Technology Data Exchange (ETDEWEB)

    Halverson, N

    2008-09-30

    In February 2000, the United States Environmental Protection Agency (EPA) Region 4 issued a proposed Total Maximum Daily Load (TMDL) for total mercury in the middle and lower Savannah River. The initial TMDL, which would have imposed a 1 ng/l mercury limit for discharges to the middle/lower Savannah River, was revised to 2.8 ng/l in the final TMDL released in February 2001. The TMDL was intended to protect people from the consumption of contaminated fish, which is the major route of mercury exposure to humans. The most bioaccumulative form of mercury is methylmercury, which is produced in aquatic environments by the action of microorganisms on inorganic mercury. Because of the environmental and economic significance of the mercury discharge limits that would have been imposed by the TMDL, the Savannah River Site (SRS) initiated several studies concerning: (1) mercury in SRS discharges, SRS streams and the Savannah River, (2) mercury bioaccumulation factors for Savannah River fish, (3) the use of clams to monitor the influence of mercury from tributary streams on biota in the Savannah River, and (4) mercury in rainwater falling on the SRS. The results of these studies are presented in detail in this report. The first study documented the occurrence, distribution and variation of total and methylmercury at SRS industrial outfalls, principal SRS streams and the Savannah River where it forms the border with the SRS. All of the analyses were performed using the EPA Method 1630/31 ultra low-level and contaminant-free techniques for measuring total and methylmercury. Total mercury at National Pollutant Discharge Elimination System (NPDES) outfalls ranged from 0.31-604 ng/l with a mean of 8.71 ng/l. Mercury-contaminated groundwater was the source for outfalls with significantly elevated mercury concentrations. Total mercury in SRS streams ranged from 0.95-15.7 ng/l. Mean total mercury levels in the streams varied from 2.39 ng/l in Pen Branch to 5.26 ng/l in Tims Branch

  1. Reactor physics studies for assessment of tramp uranium methods

    International Nuclear Information System (INIS)

    This paper presents calculation studies towards validation of a methodology for estimations of the tramp uranium mass from water chemistry measurements. Particular emphasis is given to verify, from a reactor physics point of view, the justification basis for the so-called 'Pu-based model' versus the 'U-based model' as a key assumption for the methodology. The computational studies are carried out for a typical BWR fuel assembly with CASMO-5M and MCNPX. By approximating the evolution of fissile nuclides and the fraction of 235U fissions to total fissions in different zones of a fuel rod, including tramp uranium on the clad surface, it is found that Pu gives the dominant contribution to fissions for tramp uranium after an irradiation on the outer clad surface of at least one cycle in a BWR. Thus, the use of the so-called Pu model for the determination of the tramp uranium mass (this means in particular using the yields for 239Pu fission) appears justified in the cases considered. On that basis, replacing the older U model by a Pu model is recommended. (authors)

    Full Text Available Lesson Study is an approach used for critical analysis during the teaching and learning process. The effectiveness of this approach was proven when the Ministry of Education implemented it by stages in schools. This approach was also used to enhance the development process in the teaching profession. In conjunction with this, the science program students from the Faculty of Education were also given early exposure to Lesson Study. This approach was applied by integrating it in the teaching methods through simulated microteaching. Thus, the purpose of this study was to observe the assessment process in microteaching, which integrated with the approach of Lesson Study. This study was carried out in the Chemical Teaching Methods Course in the Faculty of Education, Universiti Kebangsaan Malaysia (UKM. It focused on how the pre-service teachers assessed the elements in microteaching. A total of 27 pre-service teachers were involved in the qualitative study. This study was carried out in one 14-weeks semester. This study involved the collection and qualitative analysis of data. Data sources were derived from observation, interviews, written reports by pre-service teachers, audio recordings (mp3, and video that was transcribed verbatim. Triangulation was done on each of the data sources. The findings showed that, through Lesson Study in microteaching, pre-service teachers were able to construct skills in doing assessment based on the lesson plan, teaching approach, and students’ behaviour. Findings from this study had a positive impact on the pre-service teachers in making assessments. This is due to the fact that the microteaching of Lesson Study allowed the pre-service teachers to construct their skills in doing assessments during the lessons. The construction of these skills is important because of the school-based assessment that focuses on the assessment process is being implemented in the school curriculum in Malaysia. Hence, the construction

  5. Environmental Assessment of a Waste Incineration Tax. Case Study and Evaluation of a Framework for Strategic Environmental Assessment

    International Nuclear Information System (INIS)

    A framework for Strategic Environmental Assessment (SEA) is tested in a case study on a proposed waste incineration tax. Also included is testing of developed methods for valuation and site-dependent life cycle impact assessment. The results indicate that although a suggested waste incineration tax of 400 SEK/ton is likely to lead to environmental improvements, these are small compared to the potential improvements as shown in more visionary scenarios. In order to go in this direction a waste incineration tax based on the content of fossil carbon in the waste would be useful. The framework for SEA includes several different pathways. These have different advantages and disadvantages and provide different types of information. It is therefore suggested that they largely complement each other and that the choice of methods should be done in relation to the function of the SEA and the questions asked.

    Full Text Available Basic aim of an epidemiological study is to quantify the association between the exposure and the outcome of interest. To achieve this, the incidence of disease in a group of individuals exposed to the putative risk factors must be compared with the incidence in a group of persons not exposed. This comparison can be summarized by calculating either the ratio of the measures of disease occurrence for the two groups, which indicates the likelihood of developing the disease in the exposed individuals relative to those unexposed, or the difference between the two, which provides information about the absolute effect of the exposure in those exposed compared with those unexposed. Some terms about relative risk were explained and examine with samples in this article. [TAF Prev Med Bull 2006; 5(5.000: 374-381

    Biomagnetic studies of the gastrointestinal system can be carried out in two ways. Recording the magnetic field produced by the myenteric nervous system or created by any oral contrast mean as magnetic tracers or markers. In the first case, a SQUID magnetometer is demanded while a fluxgate magnetometer is enough in the second case. In this work, a magnetic marker was ingested by 8 healthy volunteers, in three gastric volume conditions, to measure the luminal content volume effect in the gastric emptying and to perform the quantification of the peristaltic frequencies in gastric and duodenum tract segments. The average emptying times for low luminal content, relative to the emptying time when the intake was the highest, were 43.6 ± 15.6 % and 77.3 ± 47.0 %. These results show that the biomagnetic technique is a powerful modality to estimate the effects of the gastric volume in the gastric emptying and a way to record the peristaltic frequencies.

    We examined the feasibility of using a remotely manoeuverable robot to make home hazard assessments for fall prevention. We employed use-case simulations to compare robot assessments with in-person assessments. We screened the homes of nine elderly patients (aged 65 years or more) for fall risks using the HEROS screening assessment. We also assessed the participants' perspectives of the remotely-operated robot in a survey. The nine patients had a median Short Blessed Test score of 8 (interquartile range, IQR 2-20) and a median Life-Space Assessment score of 46 (IQR 27-75). Compared to the in-person assessment (mean = 4.2 hazards identified per participant), significantly more home hazards were perceived in the robot video assessment (mean = 7.0). Only two checklist items (adequate bedroom lighting and a clear path from bed to bathroom) had more than 60% agreement between in-person and robot video assessment. Participants were enthusiastic about the robot and did not think it violated their privacy. The study found little agreement between the in-person and robot video hazard assessments. However, it identified several research questions about how to best use remotely-operated robots. PMID:24352900

    Remote assessments of individuals with a neurological disease via telemedicine have the potential to reduce some of the burdens associated with clinical care and research participation. We aim to evaluate the feasibility of conducting the Montreal Cognitive Assessment remotely in individuals with movement disorders. A pilot study derived from two telemedicine trials was conducted. In total, 17 individuals with movement disorders (8 with Parkinson disease and 9 with Huntington disease) had Montreal Cognitive Assessment examinations evaluated in-person and remotely via web-based video conferencing to primarily determine feasibility and potential barriers in its remote administration. Administering the Montreal Cognitive Assessment remotely in a sample of movement disorder patients with mild cognitive impairment is feasible, with only minor common complications associated with technology, including delayed sound and corrupted imaging for participants with low connection speeds. The Montreal Cognitive Assessment has the potential to be used in remote assessments of patients and research participants with movement disorders. PMID:25391849

    Results: Results showed that a total of 34,981 had been treated at the inpatient departments from the year 2011 to 2013. It was observed that communicable diseases constituted about 85% (30,082 of the total disease burden with viral infections being the commonest. Most of the diseases were observed to have a seasonal variation. The most common disease identified was viral fever 8713 (28.96%, secondly acute diarrheal diseases 7965(26.52% followed by enteric fever 2958 (9.83% and malaria 2443(8.12%. The least common were Rabies 80 (0.26 % and pertussis 37 (0.12%. Outbreaks of Measles and Diphtheria were also noted in this study. Conclusions: Many diseases have a seasonal variation and the burden of these diseases could be reduced if we device measures to detect the changes in their trend through the implementation of surveillance programs. The knowledge of the burden of these would also assist the health administrators in allocation of the resources. [Int J Res Med Sci 2016; 4(4.000: 1186-1192

  14. Isotope studies to assess water development in mining dump sites

    International Nuclear Information System (INIS)

    After the ending of the lignite exploitation open mining pits with dump sites of heterogeneous mixture of Tertiary and Quaternary sediments were flooded by groundwater and river water inflow forming partially acidic (pH about 2 to 3) mining lakes with high sulphate (>3000 mg/L) and iron content (>500 mg/L) (Friese et al., 1998). The renewing of the groundwater system in mining areas is a very complicated process. The knowledge of the whole as well as of parts of that process is important for the future water management and for land use. Acidification of surface and groundwater based on pyrite oxidation dominates water quality development of the groundwater and of the flooded pits. The different sulphur compounds and the distribution of sulphur sources (pyrite, sulphate, sulphide) can easily controlled by the sulphur and oxygen isotope analyses. Our studies are focused on an acidic mine lake ML 111 in the Lusatian Lignite District and on the Cospuden lignite mine south of Leipzig

    Full Text Available During the recent financial crisis of insurance domain, there were imposed new aspects that have to be taken into account concerning the risks management and surveillance activity. The insurance societies could develop internal models in order to determine the minimum capital requirement imposed by the new regulations that are to be adopted on 1 January 2016. In this respect, the purpose of this research paper is to offer a real presentation and comparing with the main solvency regulation systems used worldwide, the accent being on their common characteristics and current tendencies. Thereby, we would like to offer a better understanding of the similarities and differences between the existent solvency regimes in order to develop the best regime of solvency for Romania within the Solvency II project. The study will show that there are clear differences between the existent Solvency I regime and the new approaches based on risk and will also point out the fact that even the key principles supporting the new solvency regimes are convergent, there are a lot of approaches for the application of these principles. In this context, the question we would try to find the answer is "how could the global solvency models be useful for the financial surveillance authority of Romania for the implementation of general model and for the development of internal solvency models according to the requirements of Solvency II" and "which would be the requirements for the implementation of this type of approach?". This thing makes the analysis of solvency models an interesting exercise.

  16. Physiochemical study of NSSC effluents and assessment of principal pollutants

    International Nuclear Information System (INIS)

    Waste effluents collected from different processing units of a pulp-mill were analyzed for various physiochemical parameters i.e. appearance, pH, conductance, total dissolved and suspended solids (TDS and TSS), chemical oxygen demand (COD) and 5- days biochemical oxygen demand (BOD/sub 5/). Various ions with reference to pulping process were investigated in these effluents which include Cr, SO/sub 4/sup 2-/, SO/sub 3/sup 2-/, CO/sub 3/sup 2-/HCO/sub 3/sup 1-/, Na/sup +/, K/sup +/, Mg/sup +2/ and Ca/sup +2/. Heavy metals like Hg, Pb, Fe, Cr, Cu and Zn was also determined by atomic absorption spectrometry. The results were compared with National Environmental Quality Standards for industrial effluents. Most of the parameters were found outside the permissible limits except the temperature, pH and few cations. Effluents from NSSC process exhibited highest values of TDS, TSS, COD and BODs (these are 103174, 31866, 23340, 6864 mg/l respectively). Chief polluting characteristics of these effluents were found to be the dissolved chemicals and suspended organic matter, which are responsible for very high COD and BODs values. This study was: an effort to monitor the concentration of various pollutants in the waste effluents of pulp and paper industry with special emphasis on NSSC effluents and their contribution in environmental pollution. The hazardous effects of these effluents and different treatment methodologies have also been discussed. (author)

    2013-06-01

    Full Text Available The instrumental case study reported here adds to the literature on authentic assessment by illuminating how one secondary agricultural education instructor employed authentic assessment in the agricultural mechanics laboratory. The study was underpinned by the constructivist notion of authentic learning and assessment, or allowing students to perform what they can do. Multiple sources of data regarding assessment practices were collected from an exemplary secondary agricultural mechanics instructor who demonstrated model authentic assessment behavior by (1 setting high and fair expectations for students, (2 establishing a progressive hierarchy of skills for students to master, (3 providing continuous feedback so that students had knowledge of their progress, and (4 being committed deeply to students’ success. The four themes resonated with previous literature and provided the foundation for a pragmatic model of authentic assessment in the secondary agricultural mechanics laboratory. Future research should focus on refining the model of authentic assessment in agricultural mechanics for a larger audience, as case studies are limited in their ability to generalize. Additionally, research should be conducted to determine how authentic assessment impacts student performance on Oklahoma Agricultural Power and Technology competency examinations.

  19. Assessing atmospheric temperature data sets for climate studies

    Directory of Open Access Journals (Sweden)

    Magnus Cederlöf

    2016-07-01

    Full Text Available Observed near-surface temperature trends during the period 1979–2014 show large differences between land and ocean, with positive values over land (0.25–0.27 °C/decade that are significantly larger than over the ocean (0.06–0.12 °C/decade. Temperature trends in the mid-troposphere of 0.08-0.11 °C/decade, on the other hand, are similar for both land and ocean and agree closely with the ocean surface temperature trend. The lapse rate is consequently systematically larger over land than over the ocean and also shows a positive trend in most land areas. This is puzzling as a response to external warming, such as from increasing greenhouse gases, is broadly the same throughout the troposphere. The reduced tropospheric warming trend over land suggests a weaker vertical temperature coupling indicating that some of the processes in the planetary boundary layer such as inversions have a limited influence on the temperature of the free atmosphere. Alternatively, the temperature of the free atmosphere is influenced by advection of colder tropospheric air from the oceans. It is therefore suggested to use either the more robust tropospheric temperature or ocean surface temperature in studies of climate sensitivity. We also conclude that the European Centre for Medium-Range Weather Forecasts Reanalysis Interim can be used to obtain consistent temperature trends through the depth of the atmosphere, as they are consistent both with near-surface temperature trends and atmospheric temperature trends obtained from microwave sounding sensors.

  20. Risk assessment after coronary angioplasty with SPECT myocardial perfusion studies

    International Nuclear Information System (INIS)

    The chest pain can be use for stratifying the risk of the patients after coronary angioplasty. Nevertheless this strategy has shown to have a low accuracy in the detection of restenosis and myocardial ischemia. Aims: To establish the usefulness of the SPECT studies in the risk stratification after the coronary angioplasty. Evaluate the incidence of silent ischemia or symptomatic, and its impact on the prognosis. Method: There were included 107 patients (p) submitted to a gated SPECT between the year of the coronary angioplasty. The analysis of the images was performed according to different scores (SSS, SRS, SDS). These data was correlated with the symptoms of the patients. We define group 1 (G1) as the asymptomatic without ischemia (n 59p), group 2 (G2) as silent ischemia (n = 28p) and group 3 (G3) as symptomatic with ischemia (n = 20p). A clinical follow-up was done in search of events (target vessel revascularization, unstable angina, AMI and death). Results: Significant differences were not observed in the clinical variables between the different groups. The SSS was lower in the G1 compare with G2 and G3 (p 0.0001) and was similar between the last two, p = NS (SSS: G1: 2.2 ± 4.9; G2: 7.6 ± 5.9; G3: 9.5 ± 6.8). The SDS was greater in G3 vs. G1 and G2, p = 0.0001, and greater in G2 vs. G1, p = 0.0001 (SDS: G1: 0; G2: 4.8 ± 3.5; G3: 7.2 ± 6.5). No differences where observed in the SRS between the three groups. In the follow-up the total percentage of events was lesser when compare the G1 with the G2 and G3 (G1: 3.3%; G2 and G3: 18.7%; p 0.02). The percentage of annual events of the G3 symptomatic with ischemia (11.03%) and G2 silent ischemia (4.04%) did not present differences (p 0.7). When the events of the G2 (4.04%) were compared with the G1 (1.24%) we observed a trend to major frequency of events in the G2 (p = 0.6). Conclusions: The presence of myocardial ischemia after coronary angioplasty is a determinant of the prognosis. Nevertheless, the extension

    Background Subtalar joint(STJ)neutral position is the position typically used by clinicians to obtain a cast representation of a patient's foot before fabrication of biomechanical functional orthosis. But no method for measuring STJ neutral position has been proven accurate and reproducible by different testers. This study was conducted to investigate the STJ neutral position in normal feet in cadavers. Methods Twelve fresh-frozen specimens of amputated lower legs were used. Pressure-sensitive films were inserted into the anterior and posterior articulation of STJ. The contact areas for various foot positions and under axial loads of 600 N were determined based on the gray level of the digitized film. The STJ neutral positions were determined as the ankle-foot position where the maxlmum contact area was achieved, because the neutral position of a joint was defined as the position where the concave and convex surfaces were completely congruous. Results In ankle-foot neutral position, the contact area of STJ was(2.79±0.24)cm2. In the range of motion of adduction-abduction (ADD-ABD), the maximum contact area was(3.00±0.26)cm2 when the foot was positioned 10°of ABD (F=221.361, P<0.05). In the range of motion of dorsiflexion-plantarflexion (DF-PF), the maximum contact area was (3. 61±0. 25)cm2 when the foot was positioned 20°of DF(F=121.067, P<0.05). In the range of motion of inversion-eversion (INV-EV), the maximum contact area was(3. 14+0.26)cm2 when the foot was positioned 10°of EV(F=256. 252, P<0.05). Conclusions Joints, such as STJ, therefore, are not necessarily in neutral position when the ankle. foot is placed in the traditional concept of neutral position. The results demonstrate that the most approximate STJ neutral position was in the foot position of 10°of abduction, 20°of dorsiflexion and 10°of eversion.

    Full Text Available Spray drying has been successfully employed for the encapsulation of herbal bioactive compounds resulting in stable phytopharmaceutical preparations. Bidens pilosa L. is a South American medicinal plant with proved antimalaric, hepatoprotector and antioxidant activities, generally linked to their secondary metabolites, flavonoids and polyacetylenes. In this work the physicochemical stability of an optimized spray dried composition from a B. pilosa extract was evaluated at three different stress storage conditions in open containers and in sealed sachets. High performance liquid chromatography was employed to monitor the concentration of three marker compounds over 12 months. Color variation of the stored samples was evaluated by using a color spectrophotometer. It was observed that the concentration of the monitored compounds of the plant decreases more drastically in samples stored in open containers. The two flavonoids monitored, rutin and hyperoside, showed lower degradation than the polyacetylene. The concentration of the markers did not change significantly at the lowest temperature. With regard to color, darker hues were observed at higher temperatures and storage times. This study showed that the storage conditions cause significant impact on stability of standardized spray dried B. pilosa extract.

    2016-01-01

    This study was to examine how well fourth- and fifth-grade students demonstrated motor skill competency assessed with selected PE Metrics assessment rubrics (2009). Fourth- and fifth-grade students (n = 1,346-1,926) were assessed on their performance of three manipulative skills using the PE Metrics Assessment Rubrics during the pre-intervention year, the post-intervention year 1, and the post-intervention year 3. Descriptive statistics, independent t-test, ANOVA, and follow-up comparisons were conducted for data analysis. The results indicated that the post-intervention year 2 cohort performed significantly more competent than the pre-intervention cohort and the post-intervention year 1 cohort on the three manipulative skill assessments. The post-intervention year 1 cohort significantly outperformed the pre-intervention cohort on the soccer dribbling, passing, and receiving and the striking skill assessments, but not on the throwing skill assessment. Although the boys in the three cohorts performed significantly better than the girls on all three skills, the girls showed substantial improvement on the overhand throwing and the soccer skills from baseline to the post-intervention year 1 and the post-intervention year 2. However, the girls, in particular, need to improve striking skill. The CTACH PE was conducive to improving fourth- and fifth-grade students’ motor skill competency in the three manipulative skills. This study suggest that PE Metrics assessment rubrics are feasible tools for PE teachers to assess levels of students’ demonstration of motor skill competency during a regular PE lesson. Key points CATCH PE is an empirically-evidenced quality PE curricular that is conducive to improving students’ manipulative skill competency. Boys significantly outperformed than girls in all three manipulative skills. Girls need to improve motor skill competency in striking skill. PE Metrics are feasible assessment rubrics that can be easily used by trained

    Full Text Available This qualitative study is intended to illuminate factors that affect the generalizability of portfolio assessments of beginning teachers. By generalizability, we refer here to the extent to which the portfolio assessment supports generalizations from the particular evidence reflected in the portfolio to the conception of competent teaching reflected in the standards on which the assessment is based. Or, more practically, “The key question is, ‘How likely is it that this finding would be reversed or substantially altered if a second, independent assessment of the same kind were made?’” (Cronbach, Linn, Brennan, and Haertel, 1997, p. 1. In addressing this question, we draw on two kinds of evidence that are rarely available: comparisons of two different portfolios completed by the same teacher in the same year and comparisons between a portfolio and a multi-day case study (observation and interview completed shortly after portfolio submission intended to parallel the evidence called for in the portfolio assessment. Our formative goal is to illuminate issues that assessment developers and users can take into account in designing assessment systems and appropriately limiting score interpretations.

  4. A study on the reliability and risk assessment of nuclear power plants

    International Nuclear Information System (INIS)

    The final objective of the present study is to establish the foundations of both performing statistical analyses of various failures and potential accidents in nuclear power plants and assessing probabilistic safety. In order to achive the objective, we have chosen the review of the state of the arts in the related methodologies and the establishment of reliability analysis method as study areas in this year. The works performed are summalized here. First, the brief reviews of the present status on the Probabilistic Risk Assessment and the development of quantiative safety goal in the Unite States were completed. It has been identified that the Probabilistic Risk Assessment techniques will take important role in nuclear safety assessment as a supporting tool in coming years. In order to establish reliability analysis methodology, a computer code for updating plant specific reliability data has been developed as a part of this project. A reliability analysis system has been estabished and used to analyize the axiliary feedwater system. (Author)

    Wave energy resource is a very important ocean renewable energy. A reliable assessment of wave energy resources must be performed before they can be exploited. Compared with wave model, altimeter can provide more accuratein situ observations for ocean wave which can be as a novel method for wave energy assessment. The advantage of altimeter data is to provide accurate significant wave height observations for wave. In order to develop characteristic and advantage of altimeter data and apply altimeter data to wave energy assessment, in this study, we established an assessing method for wave energy in local sea area which is dedicated to altimeter data. This method includes three parts including data selection and processing, establishment of evaluation indexes system and criterion of regional division. Then a case study of Northwest Pacific was performed to discuss specific application for this method. The results show that assessing method in this paper can assess reserves and temporal and spatial distribution effectively and provide scientific references for the siting of wave power plants and the design of wave energy convertors.

    Ospina, Maria; Liang, Yuanyuan; Dryden, Donna M; Hooton, Nicola; Krebs Seida, Jennifer; Klassen, Terry P

    2009-01-01

    Objectives To evaluate the risk of bias tool, introduced by the Cochrane Collaboration for assessing the internal validity of randomised trials, for inter-rater agreement, concurrent validity compared with the Jadad scale and Schulz approach to allocation concealment, and the relation between risk of bias and effect estimates. Design Cross sectional study. Study sample 163 trials in children. Main outcome measures Inter-rater agreement between reviewers assessing trials using the risk of bias tool (weighted κ), time to apply the risk of bias tool compared with other approaches to quality assessment (paired t test), degree of correlation for overall risk compared with overall quality scores (Kendall’s τ statistic), and magnitude of effect estimates for studies classified as being at high, unclear, or low risk of bias (metaregression). Results Inter-rater agreement on individual domains of the risk of bias tool ranged from slight (κ=0.13) to substantial (κ=0.74). The mean time to complete the risk of bias tool was significantly longer than for the Jadad scale and Schulz approach, individually or combined (8.8 minutes (SD 2.2) per study v 2.0 (SD 0.8), P<0.001). There was low correlation between risk of bias overall compared with the Jadad scores (P=0.395) and Schulz approach (P=0.064). Effect sizes differed between studies assessed as being at high or unclear risk of bias (0.52) compared with those at low risk (0.23). Conclusions Inter-rater agreement varied across domains of the risk of bias tool. Generally, agreement was poorer for those items that required more judgment. There was low correlation between assessments of overall risk of bias and two common approaches to quality assessment: the Jadad scale and Schulz approach to allocation concealment. Overall risk of bias as assessed by the risk of bias tool differentiated effect estimates, with more conservative estimates for studies at low risk. PMID:19841007

    International Nuclear Information System (INIS)

    This presentation discussed the public relations and public opinion strategies used as part of a soils study conducted to assess the risk of mining activities in the Sudbury region to human health and the environment. The human health risk assessment (HHRA) study was conducted and administered by a multi-stakeholder technical committee attended by the public. The study was comprised of extensive soil collection and analysis; a review of historical soils data; and extensive human health and ecological risk assessments. Extensive sampling was also conducted on air, dust, and locally-produced foods. A public advisory committee was formed to disseminate scientific information to the community. Scientific data obtained in the study were reviewed by experts in various fields. Results of the study were also peer-reviewed by an independent expert review panel comprised of leading specialists in human health, toxicology, speciation, and risk assessment. The study showed that the identified risks were over-estimated in the interest of protecting human health. It was concluded that the HHRA's findings were generally accepted by the public. tabs., figs

    Forsberg, Elenita; Ziegert, Kristina; Hult, Håkan; Fors, Uno

    2016-01-01

    To avoid test-driven learning, there have been discussions regarding the use of more formative assessments in health care education to promote students' deep learning. Feedback is important in formative assessment, but many students ignore it; therefore, interventions should be introduced which stimulate them to reflect on the new knowledge. The aim for this study was to explore if Virtual Patient (VP)-based formative assessments, in connection with self-evaluations, had an impact on postgraduate pediatric nursing students' development of clinical reasoning abilities. Students' self-evaluations served as the basis for measuring progress. Data was analysed using deductive content analysis. The findings showed a clear progression of the clinical reasoning ability of the students. After the first assessment, the students described feelings of uncertainty and that their knowledge gaps were exposed. At the mid-course assessment the awareness of improved clinical reasoning was obvious and the students were more certain of knowing how to solve the VP cases. In the final assessment, self-efficacy was expressed. VP-based assessments, in connection with self-evaluations, early in the education resulted in a gain of students' own identification of the concept of clinical reasoning, awareness of what to focus on during clinical practice and visualised expected clinical competence.

    Full Text Available This paper aimed to identify the perception of undergraduate Management course students from the Federal University of Pernambuco (UFPE, Agreste Campus, about their professors’ assessment methods. A quantitative approach was employed through a questionnaire conducted on a research sample of 155 students. The data collected and analyzed revealed that the students in question pointed out didactic and bureaucratic functions as the reasons for undertaking assessments and recognized their importance only for students, as an indication of their performance. Most students stated that their feelings about the assessment processes vary according to their time of study and empathy for the discipline, and that the teaching-assessment ratio is generally positive. Assessment feedback was common practice for the sample, but there was a lack of diversity of assessment tools and those used clash with the ones they desired. In conclusion, according to the students’ perception, it is possible to develop multiple thoughts about the assessment process, driving improvements in educational practices and the formation and training of university professors.

  1. Vulnerability and Risk Assessment of Extreme Weather Events- A Case Study from Bangladesh

    2013-12-01

    Assessment of hazard, vulnerability and risk of extreme weather are essential in order to inform and implement appropriate adaptation/prevention/mitigation strategies. Due to complex nature and uncertainties in future climate change predictions, it is not feasible to detail assessment of vulnerability at detailed scales for potential hazard and risk. Though different approaches and methods exist for running hazard, vulnerability and risk assessment, but still difficult to address all physical science, engineering, and social science research. In this study, we try to discuss on the human vulnerability and risk assessment approaches, tools and techniques of natural hazard due to extreme weather events (i.e. floods, cyclone). We analyzed different approaches and methods of vulnerability and risk assessment for flood hazard based on medium (1-10 days) and seasonal (1-3 months) ensembles probabilistic forecasts. The multiple weather ensembles (EPS) forecasts of European Center for Medium Range Forecasts (ECMWF) and downscaled Community Climate System Model Version 3 (CCSM3) forecasts data were used to set up hydrological model. Due to high uncertainty in forecasts information, results summarized that data and inherent low resolutions of the information are major constrains for details comprehensive assessment. Risk and vulnerability rises to be based on multi-scale and cross-scale analyses, considering resilience dimensions and provide innovative tools for understanding, assessing and communicating probabilistic information to the users for decision making. The sectoral responses were developed with possible impacts scenarios based on uncertainty ranges to choose the most robust solution.

The BBA was administered to 141 participants who had no history of medical issues that could impact balance. A review of the normative data collected indicated little variation in total assessment scores in the age categories of 18-29, 30-39, and 40-49, due to the presence of a ceiling effect. Variations existed in scores among participants in the remaining age categories (50-59, 60-69, and 70+. These findings may imply that the BBA has its greatest discriminative power in assessing individuals with impaired balance, and/or that the BBA is not sensitive enough to detect differences in individuals with mild balance impairments. The researchers suggest future studies be conducted with the BBA to establish norms with populations with known orthopedic or neurological conditions that may impair balance. Results of these studies could then be compared with the baseline data gathered in this study to determine the BBA’s usefulness in detecting balance impairments with clinical populations.

  3. Incorporating formative assessment and science content into elementary science methods---A case study

    Science.gov (United States)

    Brower, Derek John

    Just as elementary students enter the science classroom with prior knowledge and experiences, so do preservice elementary teachers who enter the science methods classroom. Elementary science methods instructors recognize the challenges associated with preparing teachers for the science classroom. Two of these challenges include overcoming limited science content understanding and a low science teaching efficacy. Based upon research in science misconceptions, conceptual change theory, formative assessment, and science teaching efficacy, this design experiment explored the use of formative assessment in an authentic learning environment to address some of these challenges. As a case study, the goal was to identify two specific topics in science which the preservice teachers did not understand and to model consistent use of formative assessment to guide instruction in those science topics for six weeks. The research questions for this study sought to explore the design of the class while also exploring students' understanding of the science content and their understanding of formative assessment. One specific question was whether the formative data could differentiate between deeply held student misconceptions in science and incomplete science understanding. In addition, data was collected to measure changes in science teaching efficacy as well as preservice teachers' desire to use formative assessment in their own future classrooms. Based upon student interviews and a final content quiz, the participants in this study did show improved science content understanding in the areas of plant food/energy and plate tectonics. The course design implemented a variety of formative assessment tools including formative assessment probes, student science notebooks, student concept maps, a non-graded quiz, and more. The STEBI-B survey identified improved science teaching efficacy among the participants. Student final essays indicated improved understanding of formative assessment

    In this paper, the effect of continuous assessment on the learning outcomes of two chemical engineering courses is studied over a several-year period. Average grades and passing percentages of courses after the final examination are reported and also student feedback on the courses is collected. The results indicate significantly better learning results after the adoption of continuous assessment in the courses. Also student feedback suggests higher quality in teaching after the adoption of more activating teaching methods which compel students to study effectively throughout the course.

  5. Recommendations by Cochrane Review Groups for assessment of the risk of bias in studies

    2008-04-01

    Full Text Available Abstract Background Assessing the risk of bias in individual studies in a systematic review can be done using individual components or by summarizing the study quality in an overall score. Methods We examined the instructions to authors of the 50 Cochrane Review Groups that focus on clinical interventions for recommendations on methodological quality assessment of studies. Results Forty-one of the review groups (82% recommended quality assessment using components and nine using a scale. All groups recommending components recommended to assess concealment of allocation, compared to only two of the groups recommending scales (P Conclusion We found that recommendations by some groups were not based on empirical evidence and many groups had no recommendations on how to use the quality assessment in reviews. We suggest that all Cochrane Review Groups refer to the Cochrane Handbook for Systematic Reviews of Interventions, which is evidence-based, in their instructions to authors and that their own guidelines are kept to a minimum and describe only how methodological topics that are specific to their fields should be handled.

  6. Contextual assessment of organisational culture - methodological development in two case studies

    International Nuclear Information System (INIS)

    Despite the acknowledged significance of organisational culture in the nuclear field, previous cultural studies have concentrated on purely safety related matters, or been only descriptive in nature. New kinds of methods, taking into account the overall objectives of the organisation, were needed to assess culture and develop its working practices appropriately. VTT developed the Contextual Assessment of Organisational Culture (CAOC) methodology during the FINNUS programme. The methodology utilises two concepts, organisational culture and core task. The core task can be defined as the core demands and content of work that the organisation has to accomplish in order to be effective. The core task concept is used in assessing the central dimensions of the organisation's culture. Organisational culture is defined as a solution the company has generated in order to fulfil the perceived demands of its core task. The CAOC-methodology was applied in two case studies, in the Radiation and Nuclear Safety Authority of Finland and in the maintenance unit of Loviisa NPP. The aim of the studies was not only to assess the given culture, but also to give the personnel new concepts and new tools for reflecting on their organisation, their jobs and on appropriate working practices. The CAOC-methodology contributes to the design and redesign of work in complex sociotechnical systems. It strives to enhance organisations' capability to assess their current working practices and the meanings attached to them and compare these to the actual demands of their basic mission and so change unadaptive practices.

    Directory of Open Access Journals (Sweden)

    Jon P. Nelson

    2010-03-01

    Full Text Available This paper assesses the methodology employed in longitudinal studies of advertising and youth drinking and smoking behaviors. These studies often are given a causal interpretation in the psychology and public health literatures. Four issues are examined from the perspective of econometrics. First, specification and validation of empirical models. Second, empirical issues associated with measures of advertising receptivity and exposure. Third, potential endogeneity of receptivity and exposure variables. Fourth, sample selection bias in baseline and follow-up surveys. Longitudinal studies reviewed include 20 studies of youth drinking and 26 studies of youth smoking. Substantial shortcomings are found in the studies, which preclude a causal interpretation.

    In 2010, workplace-based assessment (WBA) was formally integrated as a method of formative trainee assessment into 29 basic and higher specialist medical training (BST/HST) programmes in six postgraduate training bodies in Ireland. The aim of this study is to explore how WBA is being implemented and to examine if WBA is being used formatively as originally intended. A retrospective cohort study was conducted and approved by the institution's Research Ethics Committee. A profile of WBA requirements was obtained from 29 training programme curricula. A data extraction tool was developed to extract anonymous data, including written feedback and timing of assessments, from Year 1 and 2 trainee ePortfolios in 2012-2013. Data were independently quality assessed and compared to the reference standard number of assessments mandated annually where relevant. All 29 training programmes mandated the inclusion of at least one case-based discussion (max = 5; range 1-5). All except two non-clinical programmes (93 %) required at least two mini-Clinical Evaluation Exercise assessments per year and Direct Observation of Procedural Skills assessments were mandated in 27 training programmes over the course of the programme. WBA data were extracted from 50 % of randomly selected BST ePortfolios in four programmes (n = 142) and 70 % of HST ePortfolios (n = 115) in 21 programmes registered for 2012-2013. Four programmes did not have an eligible trainee for that academic year. In total, 1142 WBAs were analysed. A total of 164 trainees (63.8 %) had completed at least one WBA. The average number of WBAs completed by HST trainees was 7.75 (SD 5.8; 95 % CI 6.5-8.9; range 1-34). BST trainees completed an average of 6.1 assessments (SD 9.3; 95 % CI 4.01-8.19; range 1-76). Feedback-of varied length and quality-was provided on 44.9 % of assessments. The majority of WBAs were completed in the second half of the year. There is significant heterogeneity with respect to the frequency and

  10. Indoor air assessment: A review of indoor-air-quality risk characterization studies

    International Nuclear Information System (INIS)

    Risk assessment methodologies provide a mechanism for incorporating scientific evidence and judgments into the risk management decision process. A risk characterization framework has been developed to provide a systematic approach for analysis and presentation of risk characterization study results. The framework was used as a tool to review published studies that provide quantitative risk estimates associated with exposure to indoor air pollutants. Comparisons of both the methods and the resulting risk estimates are presented. Critical assumptions concerning risk estimates and exposure estimates for each study are recorded on the framework. Fourteen risk characterization studies were reviewed include three studies for radon, six for environmental tobacco smoke, three for volatile organics, one for formaldehyde only, and one for asbestos. The quality and rigor of analysis varied greatly among the studies reviewed. Some of the studies clearly state that they are intended to be preliminary analyses or screening studies, others are reported as sensitivity analyses, and others are detailed risk assessments. Studies which are technically rigorous in some risk components (e.g., dose-response relationships) are often less rigorous in other components (e.g. exposure assessment)

    The objective of this study was to identify and assess opportunities for demonstration and large scale deployment of solar electric facilities in the southeast region and to define the technical, economic, and institutional factors that can contribute to an accelerated use of solar energy for electric power generation. Graphs and tables are presented indicating the solar resource potential, siting opportunities, energy generation and use, and socioeconomic factors of the region by state. Solar electric technologies considered include both central station and dispersed solar electric generating facilities. Central stations studied include solar thermal electric, wind, photovoltaic, ocean thermal gradient, and biomass; dispersed facilities include solar thermal total energy systems, wind, and photovoltaic. The value of solar electric facilities is determined in terms of the value of conventional facilities and the use of conventional fuels which the solar facilities can replace. Suitable cost and risk sharing mechanisms to accelerate the commercialization of solar electric technologies in the Southeast are identified. The major regulatory and legal factors which could impact on the commercialization of solar facilities are reviewed. The most important factors which affect market penetration are reviewed, ways to accelerate the implementation of these technologies are identified, and market entry paths are identified. Conclusions and recommendations are presented. (WHK)

  13. A preliminary study on application of risk assessment to seismic risk management of nuclear fuel facilities

    International Nuclear Information System (INIS)

    Studies on risk-informed safety regulation and/or management of nuclear installations are being carried out world widely on the background of progress in development of probabilistic safety assessment (PSA) methodology and its application. The study on PSA methodology and application is on going at the Japan Atomic Energy Agency. A PSA methodology has been developed for MOX fuel fabrication facilities in this study. A preliminary study on application of risk assessment to examine seismic risk management of nuclear fuel facilities has been also carried out as one of those research activities. A simple approach of assessing risk has been investigated based on the analytical policy so called 'graded approach' in which detail of risk analysis can be changed corresponding with the level of potential risk of facilities. Following three issues have been studied with a sample case of uranium fuel fabrication facility. (1) Approach to application of Seismic PSA to examine reasonable practicable seismic risk management, (2) Assessing method of seismic induced accident scenarios and their consequence, (3) Applicable safety level to evaluate the effectiveness of risk management.

    Peterman, Karen; Cranston, Kayla A.; Pryor, Marie; Kermish-Allen, Ruth

    2015-11-01

    This case study was conducted within the context of a place-based education project that was implemented with primary school students in the USA. The authors and participating teachers created a performance assessment of standards-aligned tasks to examine 6-10-year-old students' graph interpretation skills as part of an exploratory research project. Fifty-five students participated in a performance assessment interview at the beginning and end of a place-based investigation. Two forms of the assessment were created and counterbalanced within class at pre and post. In situ scoring was conducted such that responses were scored as correct versus incorrect during the assessment's administration. Criterion validity analysis demonstrated an age-level progression in student scores. Tests of discriminant validity showed that the instrument detected variability in interpretation skills across each of three graph types (line, bar, dot plot). Convergent validity was established by correlating in situ scores with those from the Graph Interpretation Scoring Rubric. Students' proficiency with interpreting different types of graphs matched expectations based on age and the standards-based progression of graphs across primary school grades. The assessment tasks were also effective at detecting pre-post gains in students' interpretation of line graphs and dot plots after the place-based project. The results of the case study are discussed in relation to the common challenges associated with performance assessment. Implications are presented in relation to the need for authentic and performance-based instructional and assessment tasks to respond to the Common Core State Standards and the Next Generation Science Standards.

  20. Probabilistic safety assessment precursor studies in support of the NRU research reactor life extension

    International Nuclear Information System (INIS)

    A probabilistic safety assessment program is being undertaken in support of a major upgrade planned for the NRU research reactor at the Chalk River Laboratories of Atomic Energy of Canada Limited (AECL) Research. This paper describes the objectives of the program and discusses the safety issues against which the success of the upgrade program is being judged. A licensing basis for the reactor in the form of detailed safety goals and release criteria as a function of event frequency has been proposed. An allowance has been made in the setting of the release criteria as a function of frequency such that the summing of event sequences is not a requirement to demonstrate compliance. The ability to assess each individual sequence that leads to core damage and/or fission-product release from confinement against these release criteria has, to a large extent, dictated the character of the supporting safety analyses. To identify the release frequencies in accident sequences, a probabilistic assessment comprising a number of probabilistic precursor studies is being undertaken. Descriptive event sequences are being used extensively in these studies to complement the more traditional event/fault tree techniques, to - ensure that operating and maintenance staff are involved in their preparation. Details of the program, assessment basis, and the analysis techniques being used in support of the assessment are given. (author). 4 refs, 3 figs

  1. Deep assessment: an exploratory study of game-based, multimodal learning in Epidemic

    Directory of Open Access Journals (Sweden)

    Jennifer Jenson

    2016-03-01

    Full Text Available n this study, we examine what and how intermediate age students learned from playing in a health-focused game-based digital learning environment, Epidemic. Epidemic is a playful interactive environment designed to deliver factual knowledge, invite critical understanding, and encourage effective self-care practices in dealing with viral contagious diseases, using a social networking interface to integrate both serious games and game-like multimodal design projects. Epidemic invites a playful approach to its deadly serious core concern – communicable disease – in order to see what happens when students are encouraged to critically approach information from multiple or contradictory perspectives. To identify what participants learned while interacting within Epidemic, we deployed two instructional and assessment models, noting the differences each instructional approach could potentially make, and what approach to assessment might help us evaluate game-based learning. We found that each approach provided importantly different perspectives on what and how students learned, and on the very meaning of student success. Recognizing that traditional assessment tools based in print-cultural literacy may prove increasingly ill-suited for assessing emergent multimodal literacies in game-based learning environments, this study seeks to contribute to a growing body of work on the development of novel assessments for learning.

    Full Text Available Abstract Background Stereoscopic assessment of the optic disc morphology is an important part of the care of patients with glaucoma. The aim of this study was to assess stereoviewing of stereoscopic optic disc images using an example of the new technology of autostereoscopic screens compared to the liquid shutter goggles. Methods Independent assessment of glaucomatous disc characteristics and measurement of optic disc and cup parameters whilst using either an autostereoscopic screen or liquid crystal shutter goggles synchronized with a view switching display. The main outcome measures were inter-modality agreements between the two used modalities as evaluated by the weighted kappa test and Bland Altman plots. Results Inter-modality agreement for measuring optic disc parameters was good [Average kappa coefficient for vertical Cup/Disc ratio was 0.78 (95% CI 0.62–0.91 and 0.81 (95% CI 0.6–0.92 for observer 1 and 2 respectively]. Agreement between modalities for assessing optic disc characteristics for glaucoma on a five-point scale was very good with a kappa value of 0.97. Conclusion This study compared two different methods of stereo viewing. The results of assessment of the different optic disc and cup parameters were comparable using an example of the newly developing autostereoscopic display technologies as compared to the shutter goggles system used. The Inter-modality agreement was high. This new technology carries potential clinical usability benefits in different areas of ophthalmic practice.

  3. Results of the Weeks Island Strategic Petroleum Reserve Oil Leak Risk Assessment Study

    International Nuclear Information System (INIS)

    This study evaluated multiple, long-term environmental oil-contamination risk scenarios that could result from the potential leakage of UP to 1.5 million barrels of crude oil entombed in the Weeks Island SPR mine following site decommissioning and abandonment, and up to 100 years thereafter. This risk assessment also provides continuity with similar risk evaluations performed earlier and documented in the 1995 DOE Environmental Assessment for Decommissioning the Strategic Petroleum Reserve Weeks Island Facility (EA). This current study was requested by the DOE to help them determine if their previous Finding of No Significant Impact (FONSI), in the EA, is still valid or needs to be rescinded. Based on the calculated environmental risk results (in terms of clean-up and remediation expenses) presented in this risk assessment, including the calculated average likelihoods of oil release and potential oil-leakage volumes, none of the evaluated risk events would appear to satisfy the definition of significant environmental impact in National Environmental Policy Act (NEPA) terminology. The DOE may combine these current results with their earlier evaluations and interpretations in the 1995 EA in order to assess whether the existing FONSI is still accurate, acceptable, and valid. However, from a risk evaluation standpoint, the assessment of impacts appears to be the same whether only 10,000 to 30,000 barrels of crude oil (as considered in the 1995 EA), or up to 1.5 million barrels of oil (as considered herein) are abandoned in the Weeks Island SPR facility

    2016-01-01

    Assessments of methodological and reporting quality are critical to adequately judging the credibility of a study's conclusions and to gauging its potential reproducibility. To aid those seeking to assess the methodological or reporting quality of studies relevant to toxicology, we conducted a scoping review of the available guidance with respect to four types of studies: in vivo and in vitro, (quantitative) structure-activity relationships ([Q]SARs), physico-chemical, and human observational studies. Our aims were to identify the available guidance in this diverse literature, briefly summarize each document, and distill the common elements of these documents for each study type. In general, we found considerable guidance for in vivo and human studies, but only one paper addressed in vitro studies exclusively. The guidance for (Q)SAR studies and physico-chemical studies was scant but authoritative. There was substantial overlap across guidance documents in the proposed criteria for both methodological and reporting quality. Some guidance documents address toxicology research directly, whereas others address preclinical research generally or clinical research and therefore may not be fully applicable to the toxicology context without some translation. Another challenge is the degree to which assessments of methodological quality in toxicology should focus on risk of bias - as in clinical medicine and healthcare - or be broadened to include other quality measures, such as confirming the identity of test substances prior to exposure. Our review is intended primarily for those in toxicology and risk assessment seeking an entry point into the extensive and diverse literature on methodological and reporting quality applicable to their work.

  16. Using Geographic Information Systems for Exposure Assessment in Environmental Epidemiology Studies

    Science.gov (United States)

    Nuckols, John R.; Ward, Mary H.; Jarup, Lars

    2004-01-01

    Geographic information systems (GIS) are being used with increasing frequency in environmental epidemiology studies. Reported applications include locating the study population by geocoding addresses (assigning mapping coordinates), using proximity analysis of contaminant source as a surrogate for exposure, and integrating environmental monitoring data into the analysis of the health outcomes. Although most of these studies have been ecologic in design, some have used GIS in estimating environmental levels of a contaminant at the individual level and to design exposure metrics for use in epidemiologic studies. In this article we discuss fundamentals of three scientific disciplines instrumental to using GIS in exposure assessment for epidemiologic studies: geospatial science, environmental science, and epidemiology. We also explore how a GIS can be used to accomplish several steps in the exposure assessment process. These steps include defining the study population, identifying source and potential routes of exposure, estimating environmental levels of target contaminants, and estimating personal exposures. We present and discuss examples for the first three steps. We discuss potential use of GIS and global positioning systems (GPS) in the last step. On the basis of our findings, we conclude that the use of GIS in exposure assessment for environmental epidemiology studies is not only feasible but can enhance the understanding of the association between contaminants in our environment and disease.

    2012-01-01

    In this study, we combine bibliometric techniques with a machine learning algorithm, the sequential Information Bottleneck, to assess the interdisciplinarity of research produced by the University of Hawaii NASA Astrobiology Institute (UHNAI). In particular, we cluster abstract data to evaluate Thomson Reuters Web of Knowledge subject categories as descriptive labels for astrobiology documents, assess individual researcher interdisciplinarity, and determine where collaboration opportunities might occur. We find that the majority of the UHNAI team is engaged in interdisciplinary research, and suggest that our method could be applied to additional NASA Astrobiology Institute teams in particular, or other interdisciplinary research teams more broadly, to identify and facilitate collaboration opportunities.

    2015-10-01

    As part of the retrospective evaluation of the U.S. Department of Energy s low-income Weatherization Assistance Program that was led by Oak Ridge National Laboratory (ORNL), an assessment of the impacts of weatherization on indoor air quality (IAQ) was conducted. This assessment included nearly 500 treatment and control homes across the country. Homes were monitored for carbon monoxide, radon, formaldehyde, temperature and humidity pre- and post-weatherization. This report focuses on the topic of radon and addresses issues not thoroughly discussed in the original IAQ report. The size, scope and rigor of the radon component of the IAQ study are compared to previous studies that assessed the impacts of weatherization on indoor radon levels. It is found that the ORNL study is by far the most extensive study conducted to date, though the ORNL results are consistent with the findings of the other studies. However, the study does have limitations related to its reliance on short-term measurements of radon and inability to attribute changes in radon levels in homes post-weatherization to specific weatherization measures individually or in combination.

METHOD A cross-sectional study analyzed the functional ability of ADL measure by the Katz Index, of 650 cases randomly selected from the Brazilian Brain Bank of the Ageing Brain Study Group (BBBABSG database. Sample was divided in two subsamples for the analysis (N=325, each and then stratified according to cognitive decline assessed by the Clinical Dementia Rating Scale (CDR. Factor analyses with calculations of internal consistency and invariance were performed. RESULTS Factor analysis evidenced a unidimensional instrument with optimal internal consistency, in all subgroups. Goodness of fit indices were obtained after two treatments of covariance, indicating adequacy of the scale for assessing ADL by informants. The scale is invariant to cognitive decline meaning that it can be used for subjects with or without cognitive impairment. CONCLUSION Katz Index is valid for the retrospective assessment of basic ADL by informants, with optimal reliability.

    International Nuclear Information System (INIS)

    This study characterises a notional low-level waste repository site within the Oxford clay belt, provides a conceptual design for a shallow, engineered repository at the site, and presents a rationale of the multiple-barrier design basis in sufficient detail to enable BRE to rehearse an engineering assessment. Parameters are identified which describe the repository's structural integrity, permeability and effectiveness in physical and chemical containment of nuclides by resistance to diffusive and advective transport. Such parameters may be used by the DoE as input for the mathematical modelling of the repository's post-closure performance under various release scenarios, as part of a full radiological assessment. Limitations in the analytical methods and experience base available for such assessments are identified and suggestions are made for future research activities. (author)

    Full Text Available In many countries the approval of animal research projects depends on the decisions of Animal Ethics Committees (AEC’s, which review the projects. An animal ethics review is performed as part of the authorization process and therefore performed routinely, but comprehensive information about how well the review system works is not available. This paper reviews studies that assess the performance of animal ethics committees by using Donabedian’s structure-process-outcome model. The paper points out that it is well recognised that AECs differ in structure, in their decision-making methods, in the time they take to review proposals and that they also make inconsistent decisions. On the other hand, we know little about the quality of outcomes, and to what extent decisions have been incorporated into daily scientific activity, and we know almost nothing about how well AECs work from the animal protection point of view. In order to emphasise this viewpoint in the assessment of AECs, the paper provides an example of measures for outcome assessment. The animal suffering is considered as a potential measure for outcome assessment of the ethics review. Although this approach has limitations, outcome assessment would significantly increase our understanding of the performance of AECs.

    2009-02-01

    This paper assesses the private and social profitability of current strategies for managing processionary moth (Thaumetopoea pityocampa) in Portuguese pine forests, looking at economic and environmental costs and benefits. Costs include the expenses for forest treatment and the social costs of threats to human health (dermatitis amongst others); benefits are assessed in terms of both revenue and social benefits such as carbon fixation and recreation. The evaluation was done using Cost Benefit Analysis (CBA) as an analytical framework. While this tool is currently applied to forest and environmental assessment and specific applications to pest management strategies are to be found in agricultural economics, rather few attempts have been made in the field of forest pest management. In order to assess and compare with--without options, a case-study was analysed for the Setúbal Peninsula, south of Lisbon, an area where extensive stands of maritime pine (Pinus pinaster) grow. The exercise has shown that CBA can be a valuable tool for assessing the economic and social profitability of pest management. The results demonstrate that the loss of revenues in the no-management option is not sufficient to make pest management profitable for private forest owners in the short-term. Conversely, a social profit is gained as pest management minimizes health risks for humans and avoids possible recreational losses. PMID:18336989

    Full Text Available Abstract Background Quality of life (QoL is increasingly used to characterize the impact of disease and the efficacy of interventions. Methods Prospective cohort study in patients' and proxies' homes with137 patients with dementia (age 52 to 88; Mini-Mental Status Examination (MMSE 3 to 28 and their proxies (age 43 to 90. MMSE, Behave-AD, Geriatric Depression Scale (GDS, and Bayer-ADL scale (B-ADL, and the Euroqol (EQ-5D; patient self-rating, proxy self-rating, and proxy-rating of patient. Results B-ADL impairment and Behave-AD total score increased with dementia severity (Kruskal-Wallis p Conclusion Proxies' assessment of the patients' QoL is related to the proxies' health, and the difference of patient's and proxie's QoL-rating is correlated with dementia severity even in mild dementia stages. QOL measures use ratings of the individual to assess the impact of symptoms and disorders on everyday life. In dementia patients, however, this impact is not captured since patients' and proxies' self-assessment of their own QoL do not reflect severity of disease whatsoever. Patients' and proxies' influencing variables render the score obtained with generic quality of life assessment meaningless in capturing the impact of dementia. Decisions on initiation or discontinuation of treatment or allocation of other resources for patients with dementia therefore need not depend on generic assessment of quality of life.

    Floods are a devastating kind of natural disaster. About half of the population in China lives in rural areas. Therefore, it is necessary to assess the flood disaster risk of rural housings. The results are valuable for guiding the rescue and relief goods layout. In this study, we take the severe flood disaster that happened at Kouqian Town in Jilin, China in 2010 as an example to build an risk assessment system for flood disaster on rural housings. Based on the theory of natural disaster risk formation and "3S" technology (remote sensing, geography information systems and global positioning systems), taking the rural housing as the bearing body, we assess the flood disaster risk from three aspects: hazard, exposure and vulnerability. The hazard presented as the flood submerging range and depth. The exposure presented as the values of the housing and the property in it. The vulnerability presented as the relationship between the losses caused by flood and flood depth. We validate the model by the field survey after the flood disaster. The risk assessment results highly coincide with the field survey losses. This model can be used to assess the risk of other flood events in this area. PMID:24705363

  3. Case study of residential exposure pathways: A probabilistic risk assessment using Monte Carlo simulation

    International Nuclear Information System (INIS)

    The risk assessment case study presented in this paper evaluates the potential human health risk to residential receptors exposed to benzene, toluene, ethylbenzene, and xylene from a JP-4 fuel spill. The eight residential scenario exposure pathways quantitatively assessed for carcinogenic and non-carcinogenic toxicological effects are: ingestion of groundwater, ingestion of soil, inhalation of volatiles (outdoors), inhalation of fugitive dust, dermal exposure to soil, dermal exposure while showering, inhalation of volatiles while showering, and ingestion of fruits and vegetables. Human health risks were calculated following EPA guidance documents which recommend determining a point estimate for potential risk in a baseline risk assessment (BRA) and a quantified uncertainty in that point estimate by a probabilistic risk assessment (PRA). BRAs typically use conservative estimates for exposure parameters, and consequently, the calculated risk represents an upper-bound or worst scenario that is beyond the reasonable maximum exposure (RME) without an associated quantified uncertainty. PRAs employing Monte Carlo techniques incorporate distributions for exposure parameters into the risk analysis to calculate a distribution for risk with each value in the risk distribution having a corresponding quantified uncertainty. The results of the assessment presented in this paper are examined to show the usefulness of the PRA in quantifying the uncertainty in the BRA

    Three contrasting drift risk assessment means were evaluated when predicting absolute losses of sedimenting pesticide drift from field crop sprayers namely PDPA laser measurements, wind tunnel measurements (both indirect drift risk assessment means) and field drift experiments (direct drift risk assessment means). In total, 90 PDPA laser measurements, 45 wind tunnel experiments and 61 field drift experiments were performed with 10 different spray nozzles at a pressure of 3.0 bar. The effect of nozzle size (ISO 02, 03 04 and 06) and nozzle type (standard flat fan, low-drift flat fan, air inclusion) on the amount of near-field sedimenting spray drift was studied. The reference spray application was defined as a Hardi ISO F 110 03 standard flat fan nozzle at a pressure of 3.0 bar with a nozzle or boom height of 0.50 m and a driving speed of 8 km.h(-1) for the field measurements; conditions that were always used for the comparative assessment of the different investigated nozzle-pressure combinations. A comparison is made between the results obtained with the indirect drift assessment means and the direct drift assessment method to evaluate the potential of these three different drift assessment means. Droplet size as well as droplet velocity characteristics are related with DRPt (field experiments) and DPRP (wind tunnel experiments). Because of the strong intercorrelation between droplet size and velocity characteristics for the nozzle-pressure combinations investigated in this study, simple first-order linear regressions with one of the droplet characteristics as a predictor variable, were the best choice to predict DRPt and DPRP. Results showed that with the indirect risk assessment means (wind tunnel and PDPA laser measurement), driftability experiments can be made with different spraying systems under directly comparable and repeatable conditions and both methods are suited to permit relative studies of drift risk. Moreover, based on these indirect drift

  6. A comparison of shoreline assessment study designs used for the Exxon Valdez oil spill

    International Nuclear Information System (INIS)

    Shoreline assessment studies may be used after an oil spill to determine whether an injury has occurred and estimate the extent of injuries. Design of these studies generally cannot meet the randomisation and replication requirements of classical experimental designs. For example, oil spills cannot be replicated, nor can oiling be applied randomly to experimental units (sites). Furthermore, species counts and other measures of abundance generally do not meet the assumptions of normal theory models. This leaves the statistician and principal investigators the task of finding design and analysis strategies that take into account these departures from standard statistical practices. This paper examines the study design, analysis method and statistical power (i.e. the ability to detect oil spill effects) of three shoreline assessment programs conducted after the Exxon Valdez oil spill (Exxon's Shoreline Ecology Program, the Exxon Valdez Oil Spill Council's Coastal Habitat Injury Assessment study, and NOAA's biological Monitoring Survey) and shows the types of techniques used are influenced by study objectives.

    Full Text Available Objective — This study explored first-year students’ learning and satisfaction in a required information literacy course. The study asked how students understand connections between themselves and information literacy in terms of power, society, and personal relevance to assess if students’ understanding of information literacy increased after taking the course. Student satisfaction with the course also was measured.Methods — The study used pre- and post tests and focus group session transcripts which were coded and analyzed to determine student learning and satisfaction during the regular 2008-2009 academic year at California State University, East Bay.Results — Many students entered the course without any concept of information literacy; however, after taking the course they found information literacy to be personally relevant and were able to articulate connections among information, power, and society. The majority of students were satisfied with the course. The results from analyzing the pre- and post-tests were supported by the findings from the focus group sessions.Conclusion — The results of this study are supported by other studies that show the importance of personal relevancy to student learning. In order to fully assess information literacy instruction and student learning, librarians should consider incorporating ways of assessing student learning beyond testing content knowledge and levels of competency.

    2010-09-01

    Full Text Available Pedestrians, comprising approximately 60% of the population, are among the most vulnerable road users in South Africa. The roadside environment may be an important factor influencing the nature and frequency of pedestrian fatalities. While there are audit tools for assessing the pedestrian environment in other countries, no such tool exists for South Africa. This study evaluated existing audit tools in relation to South African issues and conditions and developed a South African Pedestrian Environment Assessment Tool (PEAT. PEAT was tested at five sites in the Tshwane Metropolitan Area in Gauteng to assess its applicability. PEAT was simple to use and provided valuable information, however, appropriate measures need to be taken to address fieldworker security, especially for night-time assessments when several roadside factors, such as lighting, should be evaluated. Although it was not the focus of our study, based on our results, we suggest that the lack of pavements, pedestrian crossings and pedestrian lighting are factors that, potentially, could increase pedestrian vulnerability.

    A case study is reported to document the details of a validation process to assess the accuracy of a mathematical model to represent experiments involving thermal decomposition of polyurethane foam. The focus of the report is to work through a validation process. The process addresses the following activities. The intended application of mathematical model is discussed to better understand the pertinent parameter space. The parameter space of the validation experiments is mapped to the application parameter space. The mathematical models, computer code to solve the models and its (code) verification are presented. Experimental data from two activities are used to validate mathematical models. The first experiment assesses the chemistry model alone and the second experiment assesses the model of coupled chemistry, conduction, and enclosure radiation. The model results of both experimental activities are summarized and uncertainty of the model to represent each experimental activity is estimated. The comparison between the experiment data and model results is quantified with various metrics. After addressing these activities, an assessment of the process for the case study is given. Weaknesses in the process are discussed and lessons learned are summarized.

    External quality assessment (EQA) for the Xpert MTB/RIF assay is part of the quality system required for clinical and laboratory practice. Five newly developed EQA panels that use different matrices, including a lyophilized sample (Vircell, Granada, Spain), a dried tube specimen (CDC), liquid (Maine Molecular Quality Control, Inc. [MMQCI], Scarborough, ME), artificial sputum (Global Laboratory Initiative [GLI]), and a dried culture spot (National Health Laboratory Services [NHLS]), were evaluated at 11 GeneXpert testing sites in South Africa. The panels comprised Mycobacterium tuberculosis complex (MTBC)-negative, MTBC-positive (including rifampin [RIF] susceptible and RIF resistant), and nontuberculosis mycobacterial material that was inactivated and safe for transportation. Twelve qualitative and quantitative variables were scored as acceptable (1) or unacceptable (0); the overall panel performance score for the Vircell, CDC, GLI, and NHLS panels was 9 of 12, while the MMQCI panel scored 6 of 12 (owing to the need for cold chain maintenance). All panels showed good compatibility with Xpert MTB/RIF testing, and none showed PCR inhibition. The use of a liquid or dry matrix did not appear to be a distinguishing criterion, as both matrices had reduced scores on insufficient volumes, a need for extra consumables, and the ability to transfer to the Xpert MTB/RIF cartridge. EQA is an important component of the quality system required for diagnostic testing programs, but it must be complemented by routine monitoring of performance indicators and instrument verification. This study aims to introduce EQA concepts for Xpert MTB/RIF testing and evaluates five potential EQA panels. PMID:24789182

  15. Simulation study to assess the INWORKS study examining leukaemia among nuclear facility personnel

    International Nuclear Information System (INIS)

    The INWORKS study of leukaemia (531 cases) in a cohort of 308 thousand nuclear workers raised questions, particularly as to whether the study can possess an appropriate statistical power and what effect can be expected from potential exposures other than occupational. A simulation study using the same occupational dose distribution was performed in order to clarify these issues. The doses were augmented with the potential doses from CT examinations. A total of 100 simulations were performed using Poisson distribution with parameters corresponding to the mean doses in categories corresponding to the initial study with the relative risk coefficient 3.4 per Sv. The numbers of the simulated cases were 442-571. In relation to the occupational doses only and to the total doses, the risk coefficient estimates lay in ranges of 0.3-7.4 (mean 3.3) and 0.1-7.8 (mean 3.4), respectively. In the simulations, 93% regression estimates were statistically significant based on the 1-sided test at a 5% significance. Hence, the power of the initial study is sufficient. In most simulations, the regression estimates corresponding to the complete doses were higher than or equal to those corresponding to the occupational doses alone. (author)

Change in proportions between 1998 and 2013 was calculated.1581 paediatric surgical articles were published in 1998, and 3453 in 2013. The most commonly used design, accounting for 45% of studies in 1998 and 46.8% in 2013, was the retrospective case series. Only 1.8% of studies were RCTs in 1998, and 1.9% in 2013. Overall, in 1998, 9.8% of studies used a recommended design. In 2013, 11.9% used a recommended design (proportion increase 2.3%, 95% confidence interval 0.5% increase to 4% increase, p = 0.017.A low proportion of published paediatric surgical manuscripts utilise a design that is recommended for assessing surgical interventions. RCTs represent fewer than 1 in 50 studies. In 2013, 88.1% of studies used a less robust design, suggesting the need for a new way of approaching paediatric surgical research.

    Full Text Available BACKGROUND: The elderly EXERNET multi-centre study aims to collect normative anthropometric data for old functionally independent adults living in Spain. PURPOSE: To describe the standardization process and reliability of the anthropometric measurements carried out in the pilot study and during the final workshop, examining both intra- and inter-rater errors for measurements. MATERIALS AND METHODS: A total of 98 elderly from five different regions participated in the intra-rater error assessment, and 10 different seniors living in the city of Toledo (Spain participated in the inter-rater assessment. We examined both intra- and inter-rater errors for heights and circumferences. RESULTS: For height, intra-rater technical errors of measurement (TEMs were smaller than 0.25 cm. For circumferences and knee height, TEMs were smaller than 1 cm, except for waist circumference in the city of Cáceres. Reliability for heights and circumferences was greater than 98% in all cases. Inter-rater TEMs were 0.61 cm for height, 0.75 cm for knee-height and ranged between 2.70 and 3.09 cm for the circumferences measured. Inter-rater reliabilities for anthropometric measurements were always higher than 90%. CONCLUSION: The harmonization process, including the workshop and pilot study, guarantee the quality of the anthropometric measurements in the elderly EXERNET multi-centre study. High reliability and low TEM may be expected when assessing anthropometry in elderly population.

  2. Application of toxicogenomics in hepatic systems toxicology for risk assessment: Acetaminophen as a case study

    International Nuclear Information System (INIS)

    Hepatic systems toxicology is the integrative analysis of toxicogenomic technologies, e.g., transcriptomics, proteomics, and metabolomics, in combination with traditional toxicology measures to improve the understanding of mechanisms of hepatotoxic action. Hepatic toxicology studies that have employed toxicogenomic technologies to date have already provided a proof of principle for the value of hepatic systems toxicology in hazard identification. In the present review, acetaminophen is used as a model compound to discuss the application of toxicogenomics in hepatic systems toxicology for its potential role in the risk assessment process, to progress from hazard identification towards hazard characterization. The toxicogenomics-based parallelogram is used to identify current achievements and limitations of acetaminophen toxicogenomic in vivo and in vitro studies for in vitro-to-in vivo and interspecies comparisons, with the ultimate aim to extrapolate animal studies to humans in vivo. This article provides a model for comparison of more species and more in vitro models enhancing the robustness of common toxicogenomic responses and their relevance to human risk assessment. To progress to quantitative dose-response analysis needed for hazard characterization, in hepatic systems toxicology studies, generation of toxicogenomic data of multiple doses/concentrations and time points is required. Newly developed bioinformatics tools for quantitative analysis of toxicogenomic data can aid in the elucidation of dose-responsive effects. The challenge herein is to assess which toxicogenomic responses are relevant for induction of the apical effect and whether perturbations are sufficient for the induction of downstream events, eventually causing toxicity.

    Ecological capital assessment is currently one of the important research contents in the interdisciplinary field of ecology, resources economics, environmental economics and ecological economics. To scientifically assess ecological capital redounds to decision-makers to consider the ecological cost in economic development, and is also necessary for sustainable economic development in arid areas. Based on the theory of landscape ecology,in this paper the per unit area ecological capital values in arid areas are researched by using the Landsat TM data, CBERS satellite data, meteorological data, MODIS satellite data and other ecological data,and the RS- and GIS-based models of assessing ecological capital values in arid areas are developed.Moreover, based on the field-measured data, a case study on ecological capital assessment in the Manas River basin, Xinjiang in 2003 is carried out. The basin is divided into 4 ecological capital areas so as to quantitatively calculate the ecological capital values of the ecosystems, analyze the spatial distribution of ecological capital, and chart the maps of spatial distribution of ecological capital. The results show that the total ecological capital value of the ecosystems in the Manas River basin in 2003 was 1.49454×1011yuan RMB. In spatial distribution, the ecological capital decreases from the alpine zones to the plains and from the oases to the deserts, which accords with the distribution of vegetation zonality in this arid area.The assessed results can objectively reflect the ecological capital and its spatial distribution in the arid basin, and can also provide reference for roundly carrying out the assessment of ecological capital in arid areas.

    Food security risk assessments can provide decision-makers with actionable information to identify critical system limitations, and alternatives to mitigate the impacts of future conditions. The majority of current risk assessments have been scenario-led and results are limited by the scenarios - selected future states of the world's climate system and socioeconomic factors. A generic scenario-neutral framework for food security risk assessments is presented here that uses plausible states of the world without initially assigning likelihoods. Measures of system vulnerabilities are identified and system risk is assessed for these states. This framework has benefited greatly by research in the water and natural resource fields to adapt their planning to provide better risk assessments. To illustrate the utility of this framework we develop a case study using livestock heat stress risk within the pastoral system of West Africa. Heat stress can have a major impact not only on livestock owners, but on the greater food production system, decreasing livestock growth, milk production, and reproduction, and in severe cases, death. A heat stress index calculated from daily weather is used as a vulnerability measure and is computed from historic daily weather data at several locations in the study region. To generate plausible states, a stochastic weather generator is developed to generate synthetic weather sequences at each location, consistent with the seasonal climate. A spatial model of monthly and seasonal heat stress provide projections of current and future livestock heat stress measures across the study region, and can incorporate in seasonal climate and other external covariates. These models, when linked with empirical thresholds of heat stress risk for specific breeds offer decision-makers with actionable information for use in near-term warning systems as well as for future planning. Future assessment can indicate under which states livestock are at greatest risk

    The Cultural Formulation of Diagnosis (CFD) Model of the Diagnostic and Statistical Manual (DSM) provides a potential framework for improving the diagnostic assessment of Posttraumatic Stress Disorder (PTSD) in culturally diverse patients. We analyzed data from the Patient-Provider Encounter Study, a multisite study that examines the process of diagnosis and clinical decision-making during an initial clinical intake session, in order to examine use of CFD for PTSD diagnosis. We find that the use of the CFD in routine community settings is inconsistently or underutilized in practice, but when employed may assist the formulation and interpretation of traumatic experiences. We discuss the implications for improving the assessment of PTSD in the time-limited setting of the clinical intake encounter and across race/ethnicity. PMID:19837780

  10. Social impact assessment and public participation in China: A case study of land requisition in Guangzhou

    International Nuclear Information System (INIS)

    This study examines the current prospects for and obstacles facing the implementation of social impact assessment (SIA) and participatory planning in the People's Republic of China. During the past two decades, rapid urbanisation and the conversion of rural land for urban development have led to numerous social conflicts and tensions between the Chinese government and its people. SIA and public participation in development decisions have received increasing attention from the Chinese authorities as possible ways to tackle the problem. Based on a Guangzhou case study, this paper argues that the assessment and mitigation of adverse impacts on the community from urban development have been carried out with different objectives, core values and principles when compared with those in Western societies. It concludes that the poor prospects of SIA and collaborative planning in China lie not only in the weak framework for environmental legislation, but also in all institutions concerning state-society relations, the socialist governing ideology and traditional Chinese culture

  11. Assessment of cerebral blood flow autoregulation (CBF AR) with rheoencephalography (REG): studies in animals

    International Nuclear Information System (INIS)

    The ability of cerebral vasculature to regulate cerebral blood flow (CBF) in the face of changes in arterial blood pressure (SAP) or intracranial pressure (ICP) is an important guard against secondary ischemia in acute brain injuries, and official guidelines recommend that therapeutic decisions be guided by continuous monitoring of CBF autoregulation (AR). The common method for CBF AR monitoring, which rests on real-time derivation of the correlation coefficient (PRx) between slow oscillations in SAP and ICP is, however, rarely used in clinical practice because it requires invasive ICP measurements. This study investigated whether the correlation coefficient between SAP and the pulsatile component of the non-invasive transcranial bioimpedance signal (rheoencephalography, REG) could be used to assess the state and lower limit of CBF AR. The results from pigs and rhesus macaques affirm the utility of REG; however, additional animal and clinical studies are warranted to assess selectivity of automatic REG-based evaluation of CBF AR.

  13. Assessment of environmental exposures from agricultural pesticides in childhood leukaemia studies: Challenges and opportunities

    International Nuclear Information System (INIS)

    Pesticides are ubiquitous in environments of many rural communities due to drift from agricultural applications and home/garden use. Studies of childhood leukaemia predominantly relied on retrospective pesticide exposure assessment and parental recall of use or proximity to fields or pesticide applications. Sample size requirements mostly preclude the collection of individual-level exposure information, bio-markers or environmental measurements of pesticides prospectively in cohorts. Yet such measures can be used in nested case-control approaches or for validating exposure models that can be applied to large populations. Recently developed models incorporate geographic information system technology and environmental databases of pesticide and/or crop data to assess exposure. Models developed in California to estimate residential exposures are presented by linking addresses to agricultural pesticide application data and land-use maps. Results from exposure validation and simulation studies and exposure measurement error issues are discussed. (authors)

  14. A study for the environmental impact assessment of the leachate migration in landfills

    International Nuclear Information System (INIS)

    In Korea there are hundreds of landfill sites all over the peninsula and the leachate problem is one of the national concern. Heavy precipitation especially during hot summers creates the fast degradation of waste products in the site which accelerates the migration of the leachate. To assess the source term, in the second year study, the computational modeling to predict the potential infiltration rate of groundwater into the landfill were developed and tested for different geomembrane sets. These results shall be used to assess the total risk of the landfill site if combined with the results in the first year R and D and potential future R and D on the biosphere. In addition the generation, migration of LFG were studied and then approaches for the monitoring and controlling of LFG were discussed. (author)

    Cognitive tests of learning and memory (L&M) have been required by U.S. Environmental Protection Agency (EPA) developmental neurotoxicity test (DNT) guidelines for more than two decades. To evaluate the utility of these guidelines, the EPA reviewed 69 pesticide DNT studies. This review found that the DNT provided or could provide the point-of-departure for risk assessment by showing the Lowest Observable Adverse Effect Level (LOAEL) in 28 of these studies in relation to other reported end points. Among the behavioral tests, locomotor activity and auditory/acoustic startle provided the most LOAELs, and tests of cognitive function and the Functional Observational Battery (FOB) the fewest. Two issues arose from the review: (1) what is the relative utility of cognitive tests versus tests of unconditioned behavior, and (2) how might cognitive tests be improved? The EPA sponsored a symposium to address this. Bushnell reviewed studies in which both screening (locomotor activity, FOB, reflex ontogeny, etc.) and complex tests (those requiring training) were used within the same study; he found relatively little evidence that complex tests provided a LOAEL lower than screening tests (with exceptions). Levin reviewed reasons for including cognitive tests in regulatory studies and methods and evidence for the radial arm maze and its place in developmental neurotoxicity assessments. Driscoll and Strupp reviewed the value of serial reaction time operant methods for assessing executive function in developmental neurotoxicity studies. Vorhees and Williams reviewed the value of allocentric (spatial) and egocentric cognitive tests and presented methods for using the Morris water maze for spatial and the Cincinnati water maze for egocentric cognitive assessment. They also reviewed the possible use of water radial mazes.

  19. ACCOUNTING FOR USERS' INFLATED ASSESSMENTS OF ONLINE CATALOG SEARCH PERFORMANCE AND USEFULNESS: AN EXPERIMENTAL STUDY

    2001-01-01

    Full Text Available User-oriented approaches to information retrieval (IR system performance evaluation assign a major role to user satisfaction with search results and overall system performance. Expressed satisfaction with search results is often used as a measure of utility. Many research studies indicate that users of on-line library catalogs (OPACs and other IR systems often express satisfaction with poor search results. This phenomenon of "false positives," inflated assessments of search results and system performance, has not been adequately explained. Non-performance factors such as interface style and ease of use may have an affect on a searcher's satisfaction with search results. The research described in this report investigates this phenomenon. This paper presents the findings of an experimental study which compared users' search performance and assessments of ease of use, system usefulness, and satisfaction with search results after use of a Web OPAC or its conventional counterpart. The primary questions addressed by this research center on the influence of two experimental factors, OPAC search interface style and search task level of difficulty, on the dependent variables: actual search performance, perceptions of ease of use and system usefulness, and assessments of satisfaction with search results. The study also investigated associations between perceived ease of use, system usefulness, and satisfaction with search results. Lastly, the study looked for associations between the dependent variables and personal characteristics. No association was found between satisfaction with search results and actual search performance. Web OPAC searchers outperformed Text OPAC searchers, but search task level of difficulty is a major determinant of search success. A strong positive correlation was found between perceptions of system ease of use and assessments of search results.
