    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.

  4. 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

    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

    Prior to the discovery of the mimivirus in 2003, viruses were thought to be physically small and genetically simple. Mimivirus, with its ~750-nm particle size and its ~1.2-Mbp genome, shattered these notions and changed what it meant to be a virus. Since this discovery, the isolation and characterization of giant viruses has exploded. One of the more recently discovered giant viruses, Samba virus, is a Mimivirus that was isolated from the Rio Negro in the Brazilian Amazon. Initial characterization of Samba has revealed some structural information, although the preparation techniques used are prone to the generation of structural artifacts. To generate more native-like structural information for Samba, we analyzed the virus through cryo-electron microscopy, cryo-electron tomography, scanning electron microscopy, and fluorescence microscopy. These microscopy techniques demonstrated that Samba particles have a capsid diameter of ~527 nm and a fiber length of ~155 nm, making Samba the largest Mimivirus yet characterized. We also compared Samba to a fiberless mimivirus variant. Samba particles, unlike those of mimivirus, do not appear to be rigid, and quasi-icosahedral, although the two viruses share many common features, including a multi-layered capsid and an asymmetric nucleocapsid, which may be common amongst the Mimiviruses.

    A significant proportion of coding sequences or open reading frames discovered in the course of sequencing projects do not show any similarity with other sequences deposited with the protein databanks. In such cases the search for similarities must be performed with as many comparison algorithms as possible, so as to increase the chance of finding weak relationships. A specialised parallel hardware (SAMBA) implementing the Smith & Waterman algorithm has been developed at the 'Institut de Recherche en Informatique et Systèmes Aléatoìres' (IRISA). It makes it possible to scan protein databanks at a speed comparable with that of BLAST or FASTA. We report here a study performed with SAMBA on 814 orphan sequences from S cerevisiae and compare the results with those from BLAST and FASTA.

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.

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

    Science.gov (United States)

    Ahlfeld, R.; Belkouchi, B.; Montomoli, F.

    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

    2013-12-01

    Combinatorial peptide ligand libraries (CPLLs) have been adopted for investigating the proteomes of mango peel and pulp as well their peptidome content (the latter as captured with a C18 resin). The aim of this study was not only to perform the deepest investigation so far of the mango proteome, but also to assess the potential presence of allergens and of peptides endowed with biological activities. The proteins of peel and pulp have been captured under both native and denaturing extraction techniques. A total of 334 unique protein species have been identified in the peel vs. 2855 in the pulp, via capture with CPLLs at different pH values (2.2 and 7.2).

    Full Text Available Abstract This article discusses the impact of inter-ethnic conflict in 1999 to the multi-ethnic community life in Sambas and offers a concept of education as a modified formulation of the local wisdom in the communication aspect that the Malay ethnic community in Sambas have in responding relations between ethnic groups post-conflict of ethnics in 1999. The methodology used is literature review observation interview and documentation-based qualitative analysis. The result is that ethnic conflict 1999 in Sambas West Kalimantan causes a number of problems or moral and social impacts in some small communities of Malay. By gaining the value of local wisdom into a new form of education an effort to respond the post-conflict negative impact through cultural communication greeting of sapa and base that shows a polite language education in Malay Sambas society and even the culture is believed to be an alternative solution that can deal with inter-ethnic conflicts and prevent conflict to happen again

  10. 40LoVe and Samba are involved in Xenopus neural development and functionally distinct from hnRNP AB.

    Directory of Open Access Journals (Sweden)

    Maria Andreou

    Full Text Available Heterogeneous nuclear ribonucleoproteins (hnRNPs comprise a large group of modular RNA-binding proteins classified according to their conserved domains. This modular nature, coupled with a large choice of alternative splice variants generates functional diversity. Here, we investigate the biological differences between 40LoVe, its splice variant Samba and its pseudoallele hnRNP AB in neural development. Loss of function experiments lead to defects in neural development with reduction of eye size, which stem primarily from increased apoptosis and reduced proliferation in neural tissues. Despite very high homology between 40LoVe/Samba and hnRNP AB, these proteins display major differences in localization, which appear to be in part responsible for functional differences. Specifically, we show that the 40Love/Samba carboxy-terminal domain (GRD enables nucleocytoplasmic shuttling behavior. This domain is slightly different in hnRNP AB, leading to nuclear-restricted localization. Finally, we show that shuttling is required for 40LoVe/Samba function in neural development.

Por que para o referido intelectual o samba não poderia coexistir em meio a outras práticas culturais da folia recifense? Qual o sentido de tradição que estava defendendo para o festejo? O que estava em jogo para que o samba fosse condenado? Ao se procurar responder a essas perguntas, evidenciou-se uma cidade que se colocava em disputa pelo formato de festa desejado. E dar visibilidade a estes conflitos é compreender, naqueles "alegres" dias de Momo, não um campo de consenso harmônico, mas um meio de efetivação de embates entre diferentes práticas e tradições a serem legitimadas

  12. Development of a single-antigen magnetic bead assay (SAMBA) for the sensitive detection of HPA-1a alloantibodies using tag-engineered recombinant soluble β3 integrin.

    Timely and accurate testing for human platelet antigen 1a (HPA-1a) alloantibodies is vital for clinical diagnosis of neonatal alloimmune thrombocytopenia (NAIT). Current antigen-specific assays used for the detection of HPA-1 alloantibodies are technically very complex and cumbersome for most diagnostic laboratories. Hence, we designed and applied recombinant soluble (rs) β3 integrins displaying HPA-1a or HPA-1b epitopes for the development of a single-antigen magnetic bead assay (SAMBA). Soluble HPA-1a and HPA-1b were produced recombinantly in human embryonic kidney 293 (HEK293) cells and differentially tagged. The recombinant soluble proteins were then immobilized onto paramagnetic beads and used for analysis of HPA-1 alloantibodies by enzyme-linked immunosorbent assay (ELISA). HPA-1a serum samples (n=7) from NAIT patients, inert sera and sera containing non-HPA-1a antibodies were used to evaluate the sensitivity and specificity of the SAMBA. Fusion of V5-His or GS-SBP-His tags to the rsβ3 integrins resulted in high-yield expression. SAMBA was able to detect all HPA-1a and -1b alloantibodies recognized by monoclonal antibody-specific immobilization of platelet antigens assay (MAIPA). No cross-reactions between the sera were observed. Two out of seven of the HPA-1a alloantibody-containing sera demonstrated weak to moderate reactivity in MAIPA but strong signals in SAMBA. SAMBA provides a very reliable method for the detection of HPA-1 antibodies with high specificity and sensitivity. This simple and rapid assay can be adapted for use in any routine laboratory and can be potentially adapted for use on automated systems.

    Full Text Available Já se tornou notória a mobilização de milhares de pessoas para prestigiar o carnaval paulistano. Como o evento é atrativo turístico da cidade, é considerado motivo para investimentos do governo em obras públicas. Diante da relevância do evento carnavalesco, da estrutura complexa das agremiações e o alto nível de competitividade nos desfiles, este trabalho tem como propósito explorar o carnaval como fonte de inovação e organização. Acredita-se que o evento carnavalesco deve ser analisado não só como espetáculo, mas como fonte de teorias para a área dos estudos organizacionais. Como a investigação compreende um objeto pouco comum, as Escolas de Samba, o procedimento metodológico que melhor se enquadrou foi uma pesquisa exploratória de cunho empírico, por meio de estudo de caso e levantamento bibliográfico. A liderança é responsável por um ambiente de incentivo a interação e o aprendizado contínuo, enfatizando as competências e habilidades dos integrantes, como meio de promover ações inovadoras. Compreende-se que a inovação exige um processo metodológico para ser adotada e desenvolvida nas organizações, mas já foi possível notar que a Escola de Samba Vai Vai, dispõe de ambiente e histórico propício para ações de inovação, o que provavelmente influencia o seu bom desempenho nos desfiles.

    Felipe Costa Trotta

    2008-11-01

    Full Text Available Every esthetic experience involves symbolic sharing of tastes and representations that are particularly visible in the construction of value judgments. In popular music, musical genres work as representations through which individuals and social groups develop quality criteria that begin to guide musical experiences and shape identities. This paper discusses strategies of valuation surrounding the practice of samba, particularly those that emerged in the 1990s, motivated by the success of "romantic pagode" groups. At that time, samba became divided into two categories, i.e., "root samba" and "pagode", representing different and conflicting forms of attributing values and gaining esthetic and commercial legitimacy. As experiências estéticas implicam processos de compartilhamento simbólico de gostos e representações que se manifestam fortemente na construção de julgamentos de valor. Na música popular, os gêneros musicais funcionam como abrigos dessas representações e, através deles, os sujeitos e grupos sociais desenvolvem critérios de qualidade que passam a nortear as experiências musicais e formação de identidades. Neste trabalho, serão discutidas as estratégias de valoração que circulam em torno da prática do samba e, em especial, aquelas que surgiram na última década do século passado motivadas pelo sucesso dos grupos de pagode romântico. Neste momento, o samba passou a ser dividido no mercado entre "raiz" e "pagode", representando formas distintas e conflituosas de atribuir valor e conquistar legitimidade estética e comercial.

    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.

    Full Text Available Abstract Background Previous studies have assessed the validity of the observational study design by comparing results of studies using this design to results from randomized controlled trials. The present study examined design features of observational studies that could have influenced these comparisons. Methods To find at least 4 observational studies that evaluated the same treatment, we reviewed meta-analyses comparing observational studies and randomized controlled trials for the assessment of medical treatments. Details critical for interpretation of these studies were abstracted and analyzed qualitatively. Results Individual articles reviewed included 61 observational studies that assessed 10 treatment comparisons evaluated in two studies comparing randomized controlled trials and observational studies. The majority of studies did not report the following information: details of primary and ancillary treatments, outcome definitions, length of follow-up, inclusion/exclusion criteria, patient characteristics relevant to prognosis or treatment response, or assessment of possible confounding. When information was reported, variations in treatment specifics, outcome definition or confounding were identified as possible causes of differences between observational studies and randomized controlled trials, and of heterogeneity in observational studies. Conclusion Reporting of observational studies of medical treatments was often inadequate to compare study designs or allow other meaningful interpretation of results. All observational studies should report details of treatment, outcome assessment, patient characteristics, and confounding assessment.

    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.

    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.

    Multifaceted community interventions directed at improving food environments are emerging, but their impact on dietary change and obesity prevalence has not been documented adequately. The Healthy Communities Study (HCS) is seeking to identify characteristics and combinations of programs and policies that are associated with children’s diets and obesity-related outcomes in various types of communities across the U.S. The purpose of this paper is to describe the methods used in 2013–2015 in the HCS to assess dietary intake, school nutrition environments, and other nutrition-related behaviors. The conceptual framework of the HCS is based on the socioecological model and behaviors shown in previous studies to be related to obesity in children-guided selection of domains. Nine domains were identified as essential measures of nutrition in the HCS: (1) intake of selected foods and beverages; (2) food patterns and behaviors; (3) social support; (4) home environment; (5) school environment; (6) community environment; (7) breastfeeding history; (8) household food insecurity; and (9) dieting behaviors and body image. Children’s dietary intake was assessed using a dietary screener and up to two automated 24-hour recalls. Dietary-related behaviors were assessed by a survey administered to the parent, child, or both, depending on child age. School nutrition measures were obtained from a combination of school staff surveys and researcher observations. Information from these measures is expected to contribute to a better understanding of “what is working” to improve the dietary behaviors that are likely to prevent obesity and improve health in children.

    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

    The undergraduate curriculum in psychology profoundly reflects and shapes the discipline. Yet, reliable information on the undergraduate psychology curriculum has been difficult to acquire due to insufficient research carried out on unrepresentative program samples with disparate methods. In 2014, APA launched the first systematic effort in a decade to gather national data on the psychology major and program outcomes. We surveyed a stratified random sample of department chairs/coordinators of accredited colleges and universities in the United States that offer undergraduate courses and programs in psychology. A total of 439 undergraduate psychology programs (45.2%) completed the survey. This article summarizes, for both associate and baccalaureate programs, the results of the Undergraduate Study in Psychology. Current practices concerning the introductory course, the courses offered, core requirements, the psychology minor, and tracks/concentrations are presented. The frequency of formal program reviews and program-level assessment methods are also addressed. By extending prior research on the undergraduate curriculum, we chronicle longitudinal changes in the psychology major over the past 20 years.

    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.

    The purpose of this study was to ascertain how well different wound assessment tools meet the needs of nurses in carrying out general wound assessment and whether current tools are fit for purpose. The methodology employed was evaluation research. In order to conduct the evaluation, a literature review was undertaken to identify the criteria of an optimal wound assessment tool which would meet nurses' needs. Several freely available wound assessment tools were selected based on predetermined inclusion and exclusion criteria and an audit tool was developed to evaluate the selected tools based on how well they met the criteria of the optimal wound assessment tool. The results provide a measure of how well the selected wound assessment tools meet the criteria of the optimal wound assessment tool. No tool was identified which fulfilled all the criteria, but two (the Applied Wound Management tool and the National Wound Assessment Form) met the most criteria of the optimal tool and were therefore considered to best meet nurses' needs in wound assessment. The study provides a mechanism for the appraisal of wound assessment tools using a set of optimal criteria which could aid practitioners in their search for the best wound assessment tool.

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.

  6. Case studies in Bayesian microbial risk assessments

    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

    2014-07-01

    Full Text Available This article includes a study that examines how formative assessment in dance education is constituted in three Swedish upper secondary schools. The starting-point for the study is life-world phenomenology.  A phenomenological way of thinking entails that the human being is intersubjective, linked with and within the world and that learning requires the bodily subject´s active experience. To turn towards the things themselves and to be open and adherent to things in the world is a basic rule and the starting point for research within phenomenology. This study is based on empirical material from observations of the phenomenon formative assessment in dance. Spiegelberg´s philosophical method was used as a base for phenomenological analysis. The analysis results in three themes: modes of communication, dance-related knowledge and function of formative assessment. Formative assessment was observed in the study to commonly involve teachers´ verbal communication and visualisation. The assessment practice is a continuous activity and very rarely involves any kind of self-assessment or tests. The results were discussed and related to a life-world phenomenological view of learning and earlier research.

    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.

    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).

    Ryan, Thomas Gerald

    This practical participatory action research study illuminates the assessment praxes of four Ontario secondary level science teachers at one school using a facilitative approach. Participants were joined by a thematic concern, that is, a commitment to inform and improve assessment. Hence, two distinct sets of research questions emerged. The first involves the nature of assessment as we asked, what was the current state of assessment practice in secondary science? What were participants' initial understandings of assessment and actual practices at the onset of this research? To what extent did these initial understandings and actual practices change due to the illumination of assessment praxes through action research involvement? What was their level of awareness of current Ontario government pronouncements and in what ways did they implement this knowledge? The second theme, concerning the nature of action research, was realised by asking what did participants learn about action research? What other learning and professional gains were realised during this study? And, what did I learn about action research and assessment through my involvement in this study? Data were collected via supportive discussion groups, individual interviews, classroom visitations, journals and documentation. This professional development experience facilitated 'interactive professionalism' as teachers worked in a small group and interacted frequently in the course of planning, testing new ideas, attempting to solve different problems, and assess the effectiveness of those ideas. In addition, this action research effort was strategic and systematic, to attain a high degree of specific interactions, (personal interviews, group meetings, classroom observations, evidence collection). This series of deliberate and planned intentions helped participants solve assessment dilemmas. We developed an awareness and understanding of the need for more preservice and inservice assessment training

    The veterinary parasiticide ivermectin was selected as a case study compound within the project ERAPharm (Environmental Risk Assessment of Pharmaceuticals). Based on experimental data generated within ERAPharm and additional literature data, an environmental risk assessment (ERA) was performed mainly according to international and European guidelines. For the environmental compartments surface water, sediment, and dung, a risk was indicated at all levels of the tiered assessment approach. Only for soil was no risk indicated after the lower tier assessment. However, the use of effects data from additional 2-species and multispecies studies resulted in a risk indication for collembolans. Although previously performed ERAs for ivermectin revealed no concern for the aquatic compartment, and transient effects on dung-insect populations were not considered as relevant, the present ERA clearly demonstrates unacceptable risks for all investigated environmental compartments and hence suggests the necessity of reassessing ivermectin-containing products. Based on this case study, several gaps in the existing guidelines for ERA of pharmaceuticals were shown and improvements have been suggested. The action limit at the start of the ERA, for example, is not protective for substances such as ivermectin when used on intensively reared animals. Furthermore, initial predicted environmental concentrations (PECs) of ivermectin in soil were estimated to be lower than refined PECs, indicating that the currently used tiered approach for exposure assessment is not appropriate for substances with potential for accumulation in soil. In addition, guidance is lacking for the assessment of effects at higher tiers of the ERA, e.g., for field studies or a tiered effects assessment in the dung compartment.

    2002-04-01

    The methods involved in the safety assessment of resins used in hair-spray products have received little peer review, or debate in the published literature, despite their widespread use, in both hairdressing salons and the home. The safety assessment for these resins currently involves determining the type of lung pathology that can be caused in animal inhalation exposure studies, and establishing the no-observable-effect level (NOEL) for these pathologies. The likely human consumer exposure is determined by techniques that model the simulated exposure under "in use" conditions. From these values it is then possible to derive the likely safety factors for human exposure. An important part of this process would be to recognize the intrinsic differences between rodents and humans in terms of the respiratory doses that each species experiences during inhalation exposures, for the purpose of the safety assessment. Interspecies scaling factors become necessary when comparing the exposure doses experienced by rats, compared to humans, because of basic differences between species in lung clearance rates and the alveolar area in the lungs. The rodent inhalation data and modeled human exposure to Resin 6965, a resin polymer that is based on vinyl acetate, has been used to calculate the safety factor for human consumer exposure to this resin, under a range of "in use" exposure conditions. The use of this safety assessment process clearly demonstrates that Resin 6965 is acceptable for human consumer exposure under the conditions considered in this risk assessment.

    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 : Self-assessment is recognized as a necessary skill for lifelong learning. It is widely reported to offer numerous advantages to the learner. The research evaluated the impact of students’ and supervisors’ self-assessment and feedback training on students’ perceptions and practices of self-assessment. Moreover, it evaluated the effect of self-assessment process on students’ study strategies within a community of clinical practice.: We conducted a qualitative phenomenological study from May 2008 to December 2009. We held 37 semi-structured individual interviews with three different cohorts of undergraduate medical students until we reached data saturation. The cohorts were exposed to different contexts while experiencing their clinical years’ assessment program. In the interviews, students’ perceptions and interpretations of ‘self-assessment practice’ and ‘supervisor-provided feedback’ within different contexts and the resulting study strategies were explored.: The analysis of interview data with the three cohorts of students yielded three major themes: strategic practice of self-assessment, self-assessment and study strategies, and feedback and study strategies. It appears that self-assessment is not appropriate within a summative context, and its implementation requires cultural preparation. Despite education and orientation on the two major components of the self-assessment process, feedback was more effective in enhancing deeper study strategies.: This research suggests that the theoretical advantages linked to the self-assessment process are a result of its feedback component rather than the practice of self-assessment isolated from feedback. Further research exploring the effects of different contextual and personal factors on students’ self-assessment is needed.

    This is an interim report discussing possible guidelines for the assessment and evaluation of projects developing speech and language systems. It was prepared at the request of the European Commission DG XIII by an ad hoc study group, and is now being made available in the form in which it was submitted to the Commission. However, the report is not an official European Commission document, and does not reflect European Commission policy, official or otherwise. After a discussion of terminology, the report focusses on combining user-centred and technology-centred assessment, and on how meaningful comparisons can be made of a variety of systems performing different tasks for different domains. The report outlines the kind of infra-structure that might be required to support comparative assessment and evaluation of heterogenous projects, and also the results of a questionnaire concerning different approaches to evaluation.

  1. Environmental impact assessment as a complement of life cycle assessment. Case study: Upgrading of biogas.

    2015-08-01

    This work presents a comparison between an environmental impact assessment (EIA) and a life cycle assessment (LCA) using a case study: upgrading of biogas. The upgrading of biogas is studied using three solvents: water, physical solvent and amine. The EIA follows the requirements of the legislation of Santa Fe Province (Argentina), and the LCA follows ISO 14040. The LCA results showed that water produces a minor impact in most of the considered categories whereas the high impact in the process with amines is the result of its high energy consumptions. The positive results obtained in the EIA (mainly associated with the cultural and socioeconomic components) make the project feasible and all the negative impacts can be mitigated by preventive and remedial measures. From the strengths and weaknesses of each tool, it is inferred that the EIA is a procedure that can complement the LCA.

    of the influence of delay on survival have been subject to great uncertainties due to unmeasured confounding and measurement error. Systematic evaluation of confounding is needed. AIM: The purpose of this project is to assess confounding in studies of delay and survival in breast cancer patients. We aim to: 1......) Clarify which factors are considered confounders or intermediate variables in the literature. 2) Assess how and to what extent these factors bias survival estimates. CONSIDERATIONS: As illustrated in Figure 1, symptoms of cancer may alert patients, GP's, and hospital doctors differently and influence both...... delay and survival time in different ways. We therefore assume that the impact of confounding factors depends on the type of delay studied (e.g., patient delay, GP delay, referral delay, or treatment delay). MATERIALS & METHODS: The project includes systematic review and methodological developments...

    The potential internal occupational exposure encountered as a consequence of the {sup 232}Th-{sup 233}U fuel cycle are likely to arise predominantly from the inhalation of {sup 232}Th, {sup 233}U and ({sup 232}Th + {sup 233}U) compounds of absorption Types M and S. In the past, although direct and indirect methods for assessments of internal exposure to {sup 232}Th and its daughters were developed, standardised and employed, no such attempts have been made with regard to {sup 233}U and {sup 233}U+{sup 232}Th. Therefore, feasibility studies for assessing internal exposures to {sup 233}U have been conducted using three methods: urine bioassay, in vivo counting and measurement of thoron gas in the exhaled breath of a worker. This paper describes details of these studies and discusses the results obtained. (author)

    Several questions related to the potential for explosions are explored as this became an important subject during an enterprise risk analysis. The understanding of explosions underwent a substantial evolution in the final 20 years of the 20{sup th} century following international research projects in Europe involving several research institutes, as well gas and oil companies. This led to the development of techniques that could be used to assess the potential consequences of explosions on oil, gas and petrochemical facilities. This paper presents an overview of the potential for explosions in communities close to industrial sites or pipelines right of way (RoW), where the standard explosion assessment methods cannot be applied. With reference to experimental studies, the potential for confined explosions in buildings and Vapor Cloud Explosions is explored. Vapor Cloud Explosion incidents in rural or urban areas are also discussed. The method used for incorporating possible explosion and fire events in risk studies is also described using a case study. Standard explosion assessment methodologies and a revised approach are compared as part of an on going evaluation of risk (author)

    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.

    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

    A pilot study of Seaside, Oregon is underway, to develop methodologies for probabilistic tsunami hazard assessments that can be incorporated into Flood Insurance Rate Maps (FIRMs) developed by FEMA's National Flood Insurance Program (NFIP). Current NFIP guidelines for tsunami hazard assessment rely on the science, technology and methodologies developed in the 1970s; although generally regarded as groundbreaking and state-of-the-art for its time, this approach is now superseded by modern methods that reflect substantial advances in tsunami research achieved in the last two decades. In particular, post-1990 technical advances include: improvements in tsunami source specification; improved tsunami inundation models; better computational grids by virtue of improved bathymetric and topographic databases; a larger database of long-term paleoseismic and paleotsunami records and short-term, historical earthquake and tsunami records that can be exploited to develop improved probabilistic methodologies; better understanding of earthquake recurrence and probability models. The NOAA-led U.S. National Tsunami Hazard Mitigation Program (NTHMP), in partnership with FEMA, USGS, NSF and Emergency Management and Geotechnical agencies of the five Pacific States, incorporates these advances into site-specific tsunami hazard assessments for coastal communities in Alaska, California, Hawaii, Oregon and Washington. NTHMP hazard assessment efforts currently focus on developing deterministic, "credible worst-case" scenarios that provide valuable guidance for hazard mitigation and emergency management. The NFIP focus, on the other hand, is on actuarial needs that require probabilistic hazard assessments such as those that characterize 100- and 500-year flooding events. There are clearly overlaps in NFIP and NTHMP objectives. NTHMP worst-case scenario assessments that include an estimated probability of occurrence could benefit the NFIP; NFIP probabilistic assessments of 100- and 500-yr

    The biosimilar industry is witnessing an unprecedented growth with the newer therapeutics increasing in complexity over time. A key step towards development of a biosimilar is to establish analytical comparability with the innovator product, which would otherwise affect the safety/efficacy profile of the product. Choosing appropriate analytical tools that can fulfil this objective by qualitatively and/or quantitatively assessing the critical quality attributes (CQAs) of the product is highly critical for establishing equivalence. These CQAs cover the primary and higher order structures of the product, product related variants and impurities, as well as process related impurities, and host cell related impurities. In the present work, we use such an analytical platform for assessing comparability of five approved Granulocyte Colony Stimulating Factor (GCSF) biosimilars (Emgrast, Lupifil, Colstim, Neukine and Grafeel) to the innovator product, Neupogen(®). The comparability studies involve assessing structural homogeneity, identity, secondary structure, and product related modifications. Physicochemical analytical tools include peptide mapping with mass determination, circular dichroism (CD) spectroscopy, reverse phase chromatography (RPC) and size exclusion chromatography (SEC) have been used in this exercise. Bioactivity assessment include comparison of relative potency through in vitro cell proliferation assays. The results from extensive analytical examination offer robust evidence of structural and biological similarity of the products under consideration with the pertinent innovator product. For the most part, the biosimilar drugs were found to be comparable to the innovator drug anomaly that was identified was that three of the biosimilars had a typical variant which was reported as an oxidized species in the literature. But, upon further investigation using RPC-FLD and ESI-MS we found that this is likely a conformational variant of the biotherapeutic been

    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.

    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.

    Numerous epidemiological accounts suggest that waterpipe smoking (aka hookah, shisha, narghile) has become a global phenomenon, especially among youth. The alarming spread of waterpipe and accumulating evidence of its addictive and harmful effects represent a new threat in the global fight to limit tobacco-related morbidity and mortality. In response to waterpipe's alarming trends, major public health and tobacco control organisations have started or are considering systematic collection of data about waterpipe smoking to monitor its trends and assess its harmful effects in different societies. Such plans require coordination and agreement on epidemiological measurement tools that reflect the uniqueness of this tobacco use method, and at the same time allow comparison of waterpipe trends across time and place, and with other tobacco use methods. We started a decade ago our work to develop standardised measures and definitions for the assessment of waterpipe smoking in epidemiological studies. In this communication, we try to expand and update these assessment tools in light of our increased knowledge and understanding of waterpipe use patterns, its context and marketing, as well as the need for evidence-guided policies and regulations to curb its spread. We have assembled for this purpose a group of leading waterpipe researchers worldwide, and worked through an iterative process to develop the suggested instruments and definitions based on what we know currently about the waterpipe epidemic. While the suggested measures are by no means comprehensive, we hope that they can provide the building blocks for standard and comparable surveillance of waterpipe smoking globally.

    In the last two decades, animal models have become important tools in understanding and treating pain, and in predicting analgesic efficacy. Although rodent models retain a dominant role in the study of pain mechanisms, large animal models may predict human biology and pharmacology in certain pain conditions more accurately. Taking into consideration the anatomical and physiological characteristics common to man and pigs (median body size, digestive apparatus, number, size, distribution and communication of vessels in dermal skin, epidermal–dermal junctions, the immunoreactivity of peptide nerve fibers, distribution of nociceptive and non-nociceptive fiber classes, and changes in axonal excitability), swines seem to provide the most suitable animal model for pain assessment. Locomotor function, clinical signs, and measurements (respiratory rate, heart rate, blood pressure, temperature, electromyography), behavior (bright/quiet, alert, responsive, depressed, unresponsive), plasma concentration of substance P and cortisol, vocalization, lameness, and axon reflex vasodilatation by laser Doppler imaging have been used to assess pain, but none of these evaluations have proved entirely satisfactory. It is necessary to identify new methods for evaluating pain in large animals (particularly pigs), because of their similarities to humans. This could lead to improved assessment of pain and improved analgesic treatment for both humans and laboratory animals. PMID:24855386

    This study aims to broaden knowledge about pain expression and assessment in daily life situations in children with Autism Spectrum Disorder (ASD). The goals are to provide a description of the responses of the GED-DI, the French version of the NCCPC, and to test the internal structure validity of this scale. Thirty five children with ASD were included in this study (mean age=58months; mean developmental age=32months). The French version of the NCCPC was filled in by parents. Descriptive analysis of responses shows that children with ASD express pain through varied and common behaviours, related to different expressive markers (vocal, facial, activity, etc.). Behaviours more specific to the symptomology and disturbances of ASD are also displayed. A four-factor solution (negative emotional reaction, idiosyncratic expression, hyper-vigilance reaction, pain expression) emerges from an exploratory factor analysis that explains 54.4% of the total variance. Correlation coefficients show good psychometric qualities in terms of internal consistency, factorial validity and discriminant validity. This study provides new data about pain expression in daily life situations and shows that the French version of NCCPC adjusted to ASD children is relevant to assess pain in daily life situations.

    In 2 studies, we examined the reliability and validity of an interpersonal measure of schizoid personality disorder (SZPD) based on nonverbal behaviors and interpersonal interactions occurring during interviews. A total of 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. Across both samples, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM-SZ) exhibited adequate reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM-SZ correlated in an expected manner with features of psychopathy and antisocial personality and with independent ratings of interpersonal behavior. We address implications for assessment of personality disorder.

    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.

    2016-01-01

    Full Text Available It has been a long time that Chinese small and medium-sized enterprises (SMEs have difficulties in dealing with financial problems. As a result of the imperfect financial environment in China, SMEs cannot find the effective way to obtain the funding, especially from Chinese commercial banks. In practice, the existing credit risk assessment and management policies cannot adapt to the requirements of SMEs, which means that developing new mechanisms and management policies is necessary. Based on the previous studies and the economic realities, this paper analyzes the credit status of commercial banks and sorts out the complex background to make a valuable conclusion. In the section of credit risk assessment mechanisms for SMEs, the author compares three classical models and introduces a parameter selection method which measures the financial and non-financial factors together. Besides the theoretical section, a case of Agricultural Bank of China will be studied and the paper will focus on the credit rating system and explore the innovative service for SMEs.

    Despite impediments to travel imposed by global political and health concerns, 332 scientists and students from 32 countries gathered in Washington, D.C. in early May to celebrate the conclusion of the Joint Global Ocean Flux Study (JGOFS), and to assess both its accomplishments and the future course of research in ocean ecology and biogeochemistry.Launched in 1987 under the auspices of the Scientific Committee on Oceanic Research (SCOR), JGOFS became the first core project of the International Geosphere-Biosphere Programme (IGBP) 2 years later as its first field studies were getting underway. Global in scope and multinational and interdisciplinary from its inception, JGOFS adopted two major goals: to understand the processes controlling the cycling of carbon and other biogenic elements in the ocean and their exchange with the atmosphere and the sea floor, and to advance our capacity to predict the response of ocean systems to anthropogenic perturbations.

    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.

    1996-12-31

    The philosophical basis for the on-going international and Australian action on climate change is the precautionary principle. The version of this relevant to Australia is that agreed to by the Australian States and by the Commonwealth of Australia as expressed in the Inter-Governmental Agreement on the Environment (IGAE). This study addresses the following questions: 1. What form of assessment of the risk-weighted consequences of climate change has been undertaken, as required under the precautionary principle? This paper claims that the IPCC process constitutes the risk-weighted assessment that is needed to justify the use of the precautionary principle. 2. Reducing the risk due to climate change requires actions on the basis of some combination of environmental integrity, equity, and economic efficiency as measured by cost-benefit analysis. Is the concept of intergenerational equity consistent with cost-benefit analysis? This paper claims that the problems of valuation over future time-scales, which may range from decades to centuries, make it difficult to apply cost-benefit analysis to the problem.

    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.

    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.

  13. An assessment of the solar irradiance record for climate studies

    Directory of Open Access Journals (Sweden)

    Kopp Greg

    2014-04-01

    Full Text Available Total solar irradiance, the spatially and spectrally integrated radiant output from the Sun at a mean Sun-Earth distance of 1 astronomical unit, provides nearly all the energy driving the Earth’s climate system. Variations in this energy, particularly over long time scales, contribute to changes in Earth’s climate and have been linked to historical glaciation and inter-glacial periods as well as having a small effect on more recent global warming. Accurate measurements of solar irradiances require measurements above the Earth’s atmosphere. The total solar irradiance spaceborne record began in 1978 and has been uninterrupted since, with over a dozen instruments contributing to the present solar climate data record. I assess the required and achieved accuracies of this record with a focus on its value for climate studies.

    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

    Automatic methods to evaluate the perceptual quality of a digital video sequence have widespread applications wherever the end-user is a human. Several objective video quality assessment (VQA) algorithms exist, whose performance is typically evaluated using the results of a subjective study performed by the video quality experts group (VQEG) in 2000. There is a great need for a free, publicly available subjective study of video quality that embodies state-of-the-art in video processing technology and that is effective in challenging and benchmarking objective VQA algorithms. In this paper, we present a study and a resulting database, known as the LIVE Video Quality Database, where 150 distorted video sequences obtained from 10 different source video content were subjectively evaluated by 38 human observers. Our study includes videos that have been compressed by MPEG-2 and H.264, as well as videos obtained by simulated transmission of H.264 compressed streams through error prone IP and wireless networks. The subjective evaluation was performed using a single stimulus paradigm with hidden reference removal, where the observers were asked to provide their opinion of video quality on a continuous scale. We also present the performance of several freely available objective, full reference (FR) VQA algorithms on the LIVE Video Quality Database. The recent MOtion-based Video Integrity Evaluation (MOVIE) index emerges as the leading objective VQA algorithm in our study, while the performance of the Video Quality Metric (VQM) and the Multi-Scale Structural SIMilarity (MS-SSIM) index is noteworthy. The LIVE Video Quality Database is freely available for download1 and we hope that our study provides researchers with a valuable tool to benchmark and improve the performance of objective VQA algorithms.

    2013-01-01

    Full Text Available Language assessment allows teachers to gather information about student learning and adjust their instructional practices accordingly. When integrated with instruction, assessment can support student-centered teaching by helping instructors understand what students have learned or are able to do and what they still need to know (Shepard, 2000. However, language teachers often receive limited pre-service training in assessment and testing (Malone, 2008. To date, limited empirical work has been conducted about LCTL teacher education and language assessment literacy. This paper explores a teacher training program designed to address the assessment needs of LCTL educators. This program provides a model of evidence-based assessment training that may be useful to other teacher educators. Furthermore, data generated from the project contributes to research about LCTL teacher education and assessment literacy and suggests future directions for work in this area.

    2016-01-01

    Full Text Available Nowadays, floods are among the most impactful calamities regarding costs. Looking at the natural hazards damage data collected in the International Disaster Database (EM-DAT, it is observable a significant increase over the past four decades of both frequency of floods and associated costs. Similarly, dramatic trends are also found by analyzing other types of flood losses, such as the number of people affected by floods, homeless, injured or killed.To deal with the aforementioned rise of flood risk, more and more efforts are being made to promote integrated flood risk management, for example, the Flood Directive 2007/60/EC. The main goals of this research are the estimation of flood damages using the KULTURisk methodology and the comparing of the projected costs with the observed one. The case study is the 2002 flood in Eilenburg. According to KULTURisk methodology, two major classes of data are considered to evaluate flood risk damage: hydraulic data as regards Hazard and economic information to assess Exposure and Vulnerability This study shows the possibility to extend the lesson learned with the Eilenburg case study in other similar contexts.

    Full Text Available Ray parenchyma is an essential tissue for tree functioning and survival. This living tissue plays a major role for storage and transport of water, nutrients and non-structural carbohydrates (NSC, thus regulating xylem hydraulics and growth. However, despite the importance of rays for tree carbon and water relations, methodological challenges hamper knowledge about ray intra- and inter-tree variability and its ecological meaning. In this study we provide a methodological toolbox for soundly quantifying spatial and temporal variability of different ray features.Anatomical ray features were surveyed in different cutting planes (cross-sectional, tangential, and radial using quantitative image analysis on stem-wood micro-sections sampled from 41 mature Scots pines (Pinus sylvestris. The percentage of ray surface (PERPAR, a proxy for ray volume, was compared among cutting planes and between early- and latewood to assess measurement-induced variability. Different tangential ray metrics were correlated to assess their similarities. The accuracy of cross-sectional and tangential measurements for PERPAR estimates as a function of number of samples and the measured wood surface was assessed using bootstrapping statistical technique. Tangential sections offered the best 3D insight of ray integration into the xylem and provided the most accurate estimates of PERPAR, with 10 samples of 4 mm2 showing an estimate within ±6.0% of the true mean PERPAR (relative 95% confidence interval, CI95, and 20 samples of 4 mm2 showing a CI95 of ±4.3%. Cross-sections were most efficient for establishment of time series, and facilitated comparisons with other widely used xylem anatomical features. Earlywood had significantly lower PERPAR (5.77 vs. 6.18% and marginally fewer initiating rays than latewood. In comparison to tangential sections, PERPAR was systematically overestimated (6.50 vs. 4.92% and required approximately twice the sample area for similar accuracy. Radial

  20. Study of creep cavity growth for power plant lifetime assessment

    2001-01-01

    This report aims to the sub project lifetime assessment by creep (livslaengdspredikteringar vid kryp), which is involved in the project package strength in high temperature power plant, KME 708. The physical creep damage includes mainly cavities and their development. Wu and Sandstroem have observed that cavity size increases linearly with increasing creep strain in a 12%Cr steel. Sandstroem has showed that, based on the relations between the nucleation and growth of creep cavities with creep strain, the physical creep damage can be modelled as a function of creep strain. In the present paper the growth of creep cavity radius R in relation to time t and strain {epsilon} in low alloy and 12%Cr steels as well as a Type 347 steel has been studied. The results exhibit that the power law cavity radius with creep time (R-t) and with creep strain (R-{epsilon}) relations are found for these materials at various testing conditions. The power law R-t and R-{epsilon} relations are in most cases dependent and independent on testing conditions, respectively. The empirical power law R-{epsilon} relations give a description of cavity evolution, which can be used for lifetime assessment. Experimental data have also been compared to the estimations by the classical models for cavity growth, including the power law growth due to Hancock, the diffusion growth due to Speight and Harris, the constrained diffusion growths due to Dyson and due to Rice and the enhanced diffusion growth due to Beere. It appears that the constraint diffusion growth models give a reasonable estimation of R-{epsilon} relation in many cases. The diffusion growth model is only applicable for limited cases where the power over t in R-t relation takes about 1/3. The power law and the enhanced diffusion models are found in most cases to overestimate the cavity growth.

    The prevalence of osteoarthritis is increasing globally but current compliance with rehabilitation remains poor. This study explores whether wearable sensors can be used to provide objective measures of performance with a view to using them as motivators to aid compliance to osteoarthritis rehabilitation. More specifically, the use of a novel attachable wearable sensor integrated into clothing and inertial measurement units located in two different positions, at the waist and thigh pocket, was investigated. Fourteen healthy volunteers were asked to complete exercises adapted from a knee osteoarthritis rehabilitation programme whilst wearing the three sensors including five times sit-to-stand test, treadmill walking at slow, preferred and fast speeds. The performances of the three sensors were validated against a motion capture system and an instrumented treadmill. The systems showed a high correlation (r(2) > 0.7) and agreement (mean difference range: -0.02-0.03 m, 0.005-0.68 s) with gold standards. The novel attachable wearable sensor was able to monitor exercise tasks as well as the inertial measurement units (ICC > 0.95). Results also suggested that a functional placement (e.g., situated in a pocket) is a valid position for performance monitoring. This study shows the potential use of wearable technologies for assessing subject performance during exercise and suggests functional solutions to enhance acceptance.

    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.

    Research suggests that sedentary behavior is a risk factor for mortality. However, most studies rely on questionnaires, which are prone to reporting error. We examined the association between sedentary time assessed by actigraphy and mortality among 1839 participants, aged 45-98years, from the prospective population-based Rotterdam Study, enrolled between 2004 and 2007. Participants wore an actigraph around the wrist for seven days. Sedentary time was evaluated continuously, per 1h/day increase, and categorically in three groups (sedentary behavior and mortality over and beyond other activity measures (including physical activity (PA) and activities of daily living (ADL)) in a final model. During 11years of follow-up (median: 7.5years, interquartile range: 6.6-8.3years), 212 participants (11.5%) died. In the multivariable model, the hazard ratio (HR) and 95% confidence interval (95% CI) per 1 more hour/day sedentary time was 1.09 (1.00, 1.18). The HR (95% CI) after adjustment for PA and ADL was 1.04 (0.96, 1.13). Participants sedentary for ≥11h/day had a higher mortality risk (HR: 1.80, 95% CI: 1.14, 2.84) than those sedentary sedentary behavior is a risk factor for mortality. Further investigation is needed to examine whether this association is distinct from the effect of other measures of activity.

    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.

    Full Text Available Based on theories of assessment as well as on the pedagogical and administrative advantages Computer Assisted Assessment (CAA has to offer in foreign language learning, the study presented in this paper examines how computers can facilitate the formative assessment of EFL learners and enhance their feeling of responsibility towards monitoring their progress. The subjects of the study were twenty five 14-year-old students attending the third class of a State Gymnasium in Greece. The instruments utilized were questionnaires on motivation and learning styles, three quizzes designed with the software Hot Potatoes, a self–assessment questionnaire and an evaluation questionnaire showing the subjects’ attitudes towards the experience of using computers for assessing purposes. After reviewing formative assessment, CAA and how these two can be combined, the paper focuses on the description of the three class quizzes used in the study. Ιnformation from the questionnaires filled in by students combined with the results of the quizzes, shows how computers can be used to provide continuous ongoing measurement of students’ progress needed for formative assessment. The results are also used to show how students and teachers can benefit from formative CAA and the extent to which such kind of assessment could be applicable in the Greek state school reality.

    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

    This study is based on the theories of terrestrial exploration risk in the Beibu Gulf Economic Zone in the Guangxi Zhuang Autonomous Region. Using ArcGIS and modelling methods, the spatial distributions of resources and environmental carrying capacity, terrestrial exploration dynamics, and terrestrial exploration potential are studied and evaluated in an integrated way. The results of the study are as follows: Mashan county, Longan county, Luchuan county, et al. have some low-risk land that can be explored, and infrastructure investment should be increased in these locations. Whereas, low-risk terrestrial development is possible in Qinzhou city, Heng county, Longan county, et al. and should be carried out in a planned and gradual fashion. The medium risk regions are distributed all over the region, but are concentrated in the city area of Nanning. However, the middle and north parts of Yulin city, the south part of Chongzuo city, Qinnan district, et al. are also in the same category and priority can be given to improve the quality and efficiency of these regions. The high risk regions, mainly distribute in the Liangqin district, Yining district, Binyang county, et al. This region should focus on the development principles of priority protection, appropriate development, and point-like development. Whereas, the extremely-high-risk areas, of which more than 60% are in Tiandeng county, Daxin county, Shanglin county, et al., are unsuitable for further development. The three-dimensional risk matrix method can make up for the deficiencies of other methods and has broad prospects in regional terrestrial development risk assessment.

    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

    Monsanto employs several pragmatic approaches for evaluating the toxicity of mixtures. These approaches are similar to those recommended by many national and international agencies. When conducting hazard and risk assessments, priority is always given to using data collected directly on the mixture of concern. To provide an example of the first tier of evaluation, actual data on acute respiratory irritation studies on mixtures were evaluated to determine whether the principle of additivity was applicable to the mixture evaluated. If actual data on the mixture are unavailable, extrapolation across similar mixtures is considered. Because many formulations are quite similar in composition, the toxicity data from one mixture can be extended to a closely related mixture in a scientifically justifiable manner. An example of a family of products where such extrapolations have been made is presented to exemplify this second approach. Lastly, if data on similar mixtures are unavailable, data on component fractions are used to predict the toxicity of the mixture. In this third approach, process knowledge and scientific judgement are used to determine how the known toxicological properties of the individual fractions affect toxicity of the mixture. Three examples of plant effluents where toxicological data on fractions were used to predict the toxicity of the mixture are discussed. The results of the analysis are used to discuss the predictive value of each of the above mentioned toxicological approaches for evaluating chemical mixtures.

    The goal of the African Programme for Onchocerciasis Control (APOC) is to eliminate Onchocerciasis as a disease of public Health significance and an important constraint to socio-economic development in the 19 none OCP (Onchocerciasis Control Project) countries covered through Community-Directed Treatment with Ivermectin, CDTI. In 1998, impact assessment studies were carried out in Morogoro, Tanzania during which baseline ophthalmological parameters were established. The hypothesis being tested is that CDTI will prevent or delay progression of onchocercal eye lesions and blindness. A total of 425 subjects aged 10 years or more from 14 villages within Bwakira district ofMorogoro region in Tanzania were examined for Snellen visual acuity, ocular microfilaria, lens opacities, uveitis and posterior segment disease especially chorioretinitis and optic nerve disease. Motion Sensitivity Screening Test (MSST) was carried out as well. Microfilaria was present in the anterior chamber of nearly half (49.2%) of all subjects examined. Prevalence of blindness was extremely high at 15.2%. Onchocercal lesions were responsible for blindness in 41.5% of these, followed by cataracts (27.7%), glaucoma (10.8%) and trachoma (6.2%). The main pathway to onchocercal blindness in this population was anterior uveitis with or without secondary cataracts. There is an urgent need to get CDTI underway and institute other horizontal primary eye care measures, especially cataract backlog reduction, in order to reduce the excessive burden of avoidable blindness in this community.

    There is growing evidence to show the effectiveness of physical exercise for multiple sclerosis (MS) patients. Aim of this study was to evaluate aerobic capacity, strength, balance, and the rate of perceived exertion (RPE) after exercise, in ambulatory patients with mild MS and matched control healthy participants. Seventeen MS patients aged 48.09 ± 10.0 years, with mild MS disability (Expanded Disability Status Scale: EDSS 1.5 to 4.5) and 10 healthy sedentary age matched (41.9 ± 11.2 years) subjects volunteered for the study. MS patients underwent medical examination with resting electrocardiogram, arterial blood pressure, EDSS, and Modified Fatigue Impact Scale-MFIS. Both groups also underwent physical assessment with the Berg Balance Scale(,) test (Berg), Six Minutes Walking Test (6MWT), maximal isometric voluntary contraction (MIVC) of forearm, lower limb, shoulder strength test, and the Borg 10-point scale test. The one-way ANOVA showed significant differences for MFIS (F1.19=9.420; p<0.01), Berg (F1.19=13.125; p<0.01), handgrip MIVC (F1.19=4.567; p<0.05), lower limbs MIVC (F1.19=7.429; p<0.01), and 6MWT (F1.19=28.061; p<0.01) between groups. EDSS, Berg test and Borg scores explained 80% of 6MWT variation. Mild grade EDSS patients exhibited impaired balance, muscle strength, and low self pace-6MWT scores, whereas RPE response after the exercise was similar to that of sedentary individuals. Both groups showed similar global physiological adjustments to exercise.

    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.

    2009-04-01

    This paper evaluates uncertainties in two solute transport models based on tracer experiment data from the Upper River Narew. Data Based Mechanistic and transient storage models were applied to Rhodamine WT tracer observations. We focus on the analysis of uncertainty and the sensitivity of model predictions to varying physical parameters, such as dispersion and channel geometry. An advection-dispersion model with dead zones (Transient Storage model) adequately describes the transport of pollutants in a single channel river with multiple storage. The applied transient storage model is deterministic; it assumes that observations are free of errors and the model structure perfectly describes the process of transport of conservative pollutants. In order to take into account the model and observation errors, an uncertainty analysis is required. In this study we used a combination of the Generalized Likelihood Uncertainty Estimation technique (GLUE) and the variance based Global Sensitivity Analysis (GSA). The combination is straightforward as the same samples (Sobol samples) were generated for GLUE analysis and for sensitivity assessment. Additionally, the results of the sensitivity analysis were used to specify the best parameter ranges and their prior distributions for the evaluation of predictive model uncertainty using the GLUE methodology. Apart from predictions of pollutant transport trajectories, two ecological indicators were also studied (time over the threshold concentration and maximum concentration). In particular, a sensitivity analysis of the length of "over the threshold" period shows an interesting multi-modal dependence on model parameters. This behavior is a result of the direct influence of parameters on different parts of the dynamic response of the system. As an alternative to the transient storage model, a Data Based Mechanistic approach was tested. Here, the model is identified and the parameters are estimated from available time series data using

COPD severity may be evaluated by the Global initiative for chronic ­Obstructive Lung Disease (GOLD combined risk assessment score (GOLD score. Spirometry, body plethysmography, diffusing capacity of the lung for carbon monoxide (DLCO, and high-resolution computed tomography (HR-CT measure lung function and elucidate pulmonary pathology. This study assesses associations between GOLD score and measurements of lung function in COPD patients with and without (≤1 comorbidities. It evaluates whether the presence of comorbidities influences evaluation by GOLD score of COPD severity, and questions whether GOLD score describes morbidity rather than COPD severity.Methods: In this prospective study, 106 patients with stable COPD were included. Patients treated for lung cancer were excluded. Demographics, oxygen saturation (SpO2, modified Medical Research Council Dyspnea Scale, COPD exacerbations, and comorbidities were recorded. Body plethysmography and DLCO were measured, and HR-CT performed and evaluated for emphysema and airways disease. COPD severity was stratified by the GOLD score.

    It is known that assessment drives learning and hence a good assessment design is key to effective student development. This paper gives some case studies in effective assessment strategies within engineering. The main contribution is to demonstrate how one can simultaneously meet a number of requirements with individual assessments and therefore be efficient in both the student and staff assessment load. The paper also proposes that assessments should be challenging and the benefits of expecting students to rise to this challenge and also how one can meet many independent learning objectives in a single assignment in order to manage the overall assessment load for staff and students.

    Full Text Available Shein-Chung Chow Biostatistics and Bioinformatics, Duke University School of Medicine, Durham, NC, USA Abstract: For assessing biosimilarity of biosimilar products, the US Food and Drug Administration (FDA proposed a stepwise approach for providing totality-of-the-evidence of similarity between a proposed biosimilar product and a US-licensed (reference product. The stepwise approach starts with an assessment of critical quality attributes (CQAs that are relevant to clinical outcomes in structural and functional characterization in manufacturing process of the proposed biosimilar product. The FDA suggests that these critical quality–relevant attributes be identified and classified into three tiers depending their criticality or risk ranking. To assist the sponsors, the FDA also suggests some statistical approaches for the assessment of analytical similarity for CQAs from different tiers, namely equivalence test for Tier 1, quality range approach for Tier 2, and descriptive raw data and graphical comparison for Tier 3. In this paper, challenging issues to the FDA's recommended approaches are discussed followed by alternative methods for the assessment of analytical similarity (mainly for CQAs from Tier 1.

    Full Text Available Health care policy background: Findings from scientific studies form the basis for evidence-based health policy decisions. Scientific background: Quality assessments to evaluate the credibility of study results are an essential part of health technology assessment reports and systematic reviews. Quality assessment tools (QAT for assessing the study quality examine to what extent study results are systematically distorted by confounding or bias (internal validity. The tools can be divided into checklists, scales and component ratings. Research questions: What QAT are available to assess the quality of interventional studies or studies in the field of health economics, how do they differ from each other and what conclusions can be drawn from these results for quality assessments? Methods: A systematic search of relevant databases from 1988 onwards is done, supplemented by screening of the references, of the HTA reports of the German Agency for Health Technology Assessment (DAHTA and an internet search. The selection of relevant literature, the data extraction and the quality assessment are carried out by two independent reviewers. The substantive elements of the QAT are extracted using a modified criteria list consisting of items and domains specific to randomized trials, observational studies, diagnostic studies, systematic reviews and health economic studies. Based on the number of covered items and domains, more and less comprehensive QAT are distinguished. In order to exchange experiences regarding problems in the practical application of tools, a workshop is hosted. Results: A total of eight systematic methodological reviews is identified as well as 147 QAT: 15 for systematic reviews, 80 for randomized trials, 30 for observational studies, 17 for diagnostic studies and 22 for health economic studies. The tools vary considerably with regard to the content, the performance and quality of operationalisation. Some tools do not only include the

    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.

  3. Studies towards assessing the effects of aviation on climate

    Science.gov (United States)

    Khodayari, Arezoo

    Emissions from aviation are an important component in the overall concerns about the effects of human activities on climate. Aviation emissions modify the chemical and physical properties of the upper troposphere and lower stratosphere (UTLS) in various ways. Aircraft emit gases and particles that can either directly or indirectly affect climate and air quality, including: carbon dioxide (CO2); nitrogen oxides (NOx) that can increase ozone (O3) production and increase the destruction of methane (CH4); water vapor that under certain atmospheric conditions can lead to contrail formation; and soot and other particles that along with contrails can affect the amount and characteristics of cirrus clouds. Soot and sulfate particles can also change the cloudiness by acting as cloud condensation nuclei. Due to the high growth in air traffic that is projected to continue, it is important to understand the effects of aviation on air quality and climate. Based on then existing analyses of the emissions and their effects, the aviation contribution in changing the radiative forcing on the climate system was about 5% of the total human-related emissions (relative to 1750) in 2005 (Lee et al., 2009). This contribution is a result of various effects, especially the direct effects of CO2, NOx-induced effects, aerosol direct and indirect effects, and increased cloudiness from contrail formation and aerosols acting as cloud condensation nuclei. One of the main challenges of the aviation scientific community has been to increase the level of scientific understanding of these effects, especially with respect to those most uncertain (i.e. NOx effects, contrail-cirrus and aerosol effects). Another challenge has been to develop a simple climate model (SCM) that has the level of sophistication necessary to accurately assess aviation induced climate effects while being easy to use by policy makers for use in policy considerations. The main objectives in this study were: (1) to evaluate the

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

    Directory of Open Access Journals (Sweden)

    Daniel W Good

    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. Image analysis was performed with Image Pro Premier to determine the histology at each measurement point.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.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 results provide useful data for which to continue to

    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.

    Accurate and effective assessment of strategic alternatives of an organization directly affects the decision-making and execution of its development strategy. In evaluation of strategic alternatives, relevant elements from both internal and external environments of an organization must be considered. In this paper we use strategic assessment model to evaluate strategic alternatives of an air-conditioning company. Strategic objectives and alternatives of the company are developed through analysis of the competitive environment,key competitors and internal conditions. The environment factors are classified into internal, task, and general opportunities and threats. Analytical hierarchy process, subjective probabilities, entropy concept,and utility theory are used to enhance decision-maker's ability in evaluating strategic alternatives. The evaluation results show that the most effective strategic alternative for the company is to reduce types of products, concentrate its effort on producing window-type and cupboard-type air-conditioners, enlarge the production scale, and pre-empt the market. The company has made great progress by implementing this alternative. We conclude that SAM is an appropriate tool for evaluating strategic alternatives.

    Statistical parametric mapping (SPM) has become the technique of choice to statistically evaluate positron emission tomography (PET), functional magnetic resonance imaging (fMRI), and single photon emission computed tomography (SPECT) functional brain studies. Nevertheless, only a few methodological studies have been carried out to assess the performance of SPM in SPECT. The aim of this paper was to study the performance of SPM in detecting changes in regional cerebral blood flow (rCBF) in hypo- and hyperperfused areas in brain SPECT studies. The paper seeks to determine the relationship between the group size and the rCBF changes, and the influence of the correction for degradations. The assessment was carried out using simulated brain SPECT studies. Projections were obtained with Monte Carlo techniques, and a fan-beam collimator was considered in the simulation process. Reconstruction was performed by using the ordered subsets expectation maximization (OSEM) algorithm with and without compensation for attenuation, scattering, and spatial variant collimator response. Significance probability maps were obtained with SPM2 by using a one-tailed two-sample t-test. A bootstrap resampling approach was used to determine the sample size for SPM to detect the between-group differences. Our findings show that the correction for degradations results in a diminution of the sample size, which is more significant for small regions and low-activation factors. Differences in sample size were found between hypo- and hyperperfusion. These differences were larger for small regions and low-activation factors, and when no corrections were included in the reconstruction algorithm.

  14. Risk of falls in Brazilian elders with and without low back pain assessed using the Physiological Profile Assessment: BACE study

    Directory of Open Access Journals (Sweden)

    Nayza M. B. Rosa

    Full Text Available ABSTRACT Background Low back pain (LBP is a common musculoskeletal condition among elders and is associated with falls. However, the underlying biological risk factors for falling among elders with LBP has been poorly investigated. The Physiological Profile Assessment (PPA is a validated fall-risk assessment tool that involves the direct assessment of sensorimotor abilities and may contribute to the understanding of risk factors for falls among elders with LBP. Objective To assess fall risk using the PPA in elders with and without LBP. Method This is an observational, comparative, cross-sectional study with elders aged ≥65 years. The present study was conducted with a subsample of participants from the Back Complaints in the Elders (BACE - Brazil study. Fall risk was assessed using the PPA, which contains five tests: visual contrast sensitivity, hand reaction time, quadriceps strength, lower limb proprioception, and postural sway. Results Study participants included 104 individuals with average age of 72.3 (SD=4.0 years, divided into two groups: GI 52 participants with LBP; GII 52 participants without LBP. The participants with LBP had a significantly higher fall risk (1.10 95% CI 0.72 to 1.48, greater postural sway (49.78 95% CI 13.54 to 86.01, longer reaction time (58.95 95% CI 33.24 to 84.65, and lower quadriceps strength (–4.42 95% CI –8.24 to –0.59 compared to asymptomatic participants. There was no significant difference for vision and proprioception tests between LBP and non-LBP participants. Conclusion Elders with LBP have greater risk for falls than those without LBP. Our results suggest fall-risk screening may be sensible in elders with LBP.

    Traditional deterministic approaches for small signal stability assessment (SSSA) are unable to properly reflect the existing uncertainties in real power systems. Hence, the probabilistic analysis of small signal stability (SSS) is attracting more attention by power system engineers. This paper discusses and compares two probabilistic methodologies for SSSA, which are based on the two point estimation method and the so-called Monte Carlo method, respectively. The comparisons are based on the results obtained for several power systems of different sizes and with different SSS performance. It is demonstrated that although with an analytical approach the amount of computation of probabilistic SSSA can be reduced, the different degrees of approximations that are adopted, lead to deceptive results. Conversely, Monte Carlo based probabilistic SSSA can be carried out with reasonable computational effort while holding satisfactory estimation precision. (author)

The proliferation status was significantly higher in histologically atypical than in typical carcinoids. Moreover, using a 4% cutoff, we observed a significant difference for the 4-year overall survival rate. Semiquantitative analysis of the proliferation index by KI-67 immunostaining seemed to be an effective means of identifying high risk subsets among patients with histologically atypical carcinoids and for whom adjuvant chemotherapy could be proposed.

    HIV/AIDS, suicide, violence, and barriers to health care access among transgender people were explored using two needs assessment surveys conducted in Philadelphia in 1997. A total of 182 people responded to a face-to-face interview or self-administered mail survey: 113 male-to-female individuals and 69 female-to-male individuals. About three-fifths of respondents had engaged in unprotected sexual activity during the past 12 months. The risk for HIV infection from unprotected sex was significantly higher among respondents of color than among white respondents. About one-third (30.1 percent) of respondents had attempted suicide. More than half of respondents had been forced to have sex, 56.3 percent had experienced violence in their homes, and 51.3 percent had been physically abused. Twenty-six percent of respondents had been denied medical care because they were transgender. These findings suggest that prevention services that specifically address HIV/AIDS, suicide, and violence among transgender people are urgently needed.

There are different characteristics such as courage, hardness, braveness, which could help an entrepreneur reach his/her goals. In this paper, we present an empirical study to learn more about students who are supposed to act as entrepreneur to create jobs in different fields of accounting, computer science, mechanical engineering, etc. In this paper, There are seven aspects of accepting reasonable risk, locus of control, the need for success, mental health conditions, being pragmatic, tolerating ambiguity, dreaming and the sense of challenging in our study to measure the level of entrepreneurship. We implement ANOVA test to measure different entrepreneurship characteristics of students who study in various educational fields. The case study is associated with Sama private university located in city of Zanjan/Iran. The results indicate that there are not meaningful differences among pairwise comparison of many engineering fields.

    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.

    Commonly, it is said that there is lack of communication among scientists, conservators, restorers, project managers and architects. But sometimes this communication flows, and we can find enormous benefits from and for all the participating agents. This is the case we present in this work, in which technical agents in charge of the restoration of a building, asked for some scientific advice to perform the restoration of a heritage building. The results were successful and fantastic for both of them, in terms of one part asking for consultation and the other answering to the demands and resolving real problems. This is the case of a marvellous Renaissance building (Medinaceli Dukes palace, 15th-16th centuries) in the central area of Spain (Cogolludo, Guadalajara). Focused on the restoration project, we were asked for consultancy on how to solve matters like the assessment of the already fixed in project cleaning method for the stone façades, the efficacy and durability methods for some conservation products to be applied, the presence or not of a patina on the stone; the viability of using some restoration mortars, and the origin of some efflorescences that came out just after placed in the building a restoration rendering mortar. Responses to these matters were answered by performing tests both in the lab and on site in the building. The efficiency and effects on stone of the blasting cleaning method was assessed by first analysing the nature and thickness of the surface deposits to be removed (SEM-EDS analyses); secondly, roughness and colour measurements were performed, and thirdly, SEM-EDS analyses were carried out again to determine whether the cleaning method was able to remove part of the surface deposits, completely, or even part of the stone substrate. Some conservation products were tested on stone specimens, both their efficacy and their durability, concluding that it was better not to apply any of them. A patina was found on the stone façade under SEM

    Vascular and endothelial dysfunction (VED) is emerging as a potential set of early markers of cardiovascular disease risk and tests for its measurement have been widely used in clinical research. The aim of this viewpoint is to describe and discuss the current usage of these measures in well-designed nutritional trials, using the potential relationship between fruit juice intake and VED as example. A search was conducted using the NHS evidence portal including studies published in English between January 1980 and October 2013. Only 10 suitable studies were selected, which investigated the effect of fruit juice intake on VED, among which 4 interventions used flow-mediated dilatation, 2 arterial stiffness, 2 a combination of arterial stiffness and flow-mediated dilatation, 2 carotid intimal media thickness and 1 iontophoresis with laser Doppler. Despite minimal effects reported on classical CVD markers, such as lipids, 8 out of the 10 identified studies reported an effect on endothelial function following juice consumption, indicating that VED tests can be effectively used in human dietary interventions to identify relationships between bioactive compounds from fruit and CVD risk. However, paucity of available data, scarcity of compound bioavailability and metabolism information, strong heterogeneity among experimental methodologies and a number of limitations to study designs, still limit the interpretation of the results obtained through these measures. Future, well-designed studies with greater attention to consider use of VED measures are needed to strengthen the utility of VED tests in nutrition research such as those investigating the impact of polyphenol-rich juices and CVD risk.

    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.

    Full Text Available Abstract Background "Examinations drive students' learning." This statement refers to what is assumed to be one of the strongest relationships in education. We explored in this research how and why students differ in their approaches to learning, how assessment affects deep learning, and which barriers stand in the way of good assessment and learning in the clinical years of a Problem Based Learning (PBL graduate entry medical curriculum. Findings Method: We conducted a qualitative, phenomenological study using semi-structured group interviews with students and semi-structured individual interviews with teachers and students. The transcripts were analyzed, and themes were identified. Setting: The research was conducted at the King Saud bin Abdulaziz University for Health Sciences, College of Medicine, Riyadh, Saudi Arabia from November 2007 to March 2008. Results: A total of 28 students participated in 7 focus group interviews. Semi-structured individual interviews were conducted with 12 teachers and 12 students. The analysis yielded four themes: summative assessment, formative assessment, continuous assessment of clinical attachments, and learning objectives. Conclusions The results of this study confirm that assessment affects students' perceptions of learning and how they learn. These effects are not uniformly positive. According to the students, the predominantly summative assessment program offers little inducement to engage in deep learning. They express a clear preference for formative assessment, which may foster a deeper approach to learning. Efforts to achieve more clinically relevant assessment with adequate balance between the various types of assessment are required. Research is needed to decide this balance.

    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.

    Based on a thorough review of the available literature in the delayed-onset muscle soreness (DOMS) model, we identified multiple study design characteristics that are considered to be normative in acute pain research but have not been followed in a majority of published DOMS experiments. We designed an analgesic investigation using the DOMS model that both complied with current scientifically accepted standards for the conduct of analgesic studies and demonstrated reasonable assay sensitivity. This randomized, double-blind, placebo-controlled within-subject study compared the efficacy of topical diclofenac sodium 1% with a matching placebo in reducing pain associated with DOMS. After exercise, subjects reporting DOMS received topical diclofenac sodium gel 1% (DSG 1%) applied to one leg and placebo to the other every 6 hours for 48 hours. Pain intensity was assessed at rest, upon standing, and when walking in the 48 hours after initial drug application (T0). The primary end point was the reduction in pain intensity (SPID 24) on walking. Subjects receiving DSG 1% had less pain while walking compared with those receiving placebo at 24 hours (SPID 24 = 34.9 [22.9] and 23.6 [19.4], respectively; P = 0.032). This investigation used experimental techniques that have been vetted in the field of exercise physiology and superimposed techniques that are considered to be best practice in the field of analgesic research. Over time and with the help of colleagues in both fields of study, similar investigations will validate design features that impact the assay sensitivity of analgesic end points in DOMS models. In addition, the study confirmed the analgesic efficacy of topical DSG 1% over placebo in subjects experiencing DOMS.

    The goal of this in vitro study was to identify the most suitable dye for endodontic dye leakage studies, which could be a further step towards standardisation. The root canals of 70 extracted, single-rooted human adult teeth were enlarged to apical size 50 using hand instruments. The teeth were divided into seven groups (n = 10 each), and all root canals were completely filled by injection with one of the following dyes: methylene blue 0.5% and 5%, blue ink, black ink, eosin 5%, basic fuchsin 0.5% and drawing ink. Transverse root sections from the coronal, middle and apical part of the roots were examined, and the percentage of the dentine penetrated by dye was evaluated by software-supported light microscopy. In addition, the range of particle size of drawing ink particles was evaluated. There were conspicuous differences in the relative dye penetration into the root dentine and the penetration behaviour in the different root sections (two-way ANOVA, both p < 0.0001). One dye (drawing ink) penetrated less into the root dentine compared with all the others (p <0.0001). The particle size of this agent (0.1-2 microm) corresponds best with the size range of a representative selection of 21 species of pathogenic endodontic bacteria. Compared to the other dyes tested, drawing ink appears to be superior for use in endodontic dye leakage studies. The penetration behaviour into the root dentine of all the other dyes tested might be one factor that limits the applicability of these dyes in dye leakage studies.

    Objectives. To review the contribution of the Nurses’ Health Studies (NHSs) to identifying epidemiological factors associated with multiple skin diseases, including skin cancer, psoriasis, and other inflammatory and autoimmune skin diseases. Methods. We carried out a narrative review of NHS articles published between 1976 and 2016. Results. The NHSs have identified environmental and lifestyle factors related to psoriasis, supporting obesity and smoking as psoriasis risk factors; associations between psoriasis and diabetes, myocardial infarction, and Crohn’s disease, supporting psoriasis as a systemic disorder; and associations of pigmentary traits, ultraviolet radiation, and lifestyle factors such as citrus consumption with risk of skin cancer. Genetic studies have identified novel genetic loci for skin pigmentation (e.g., IRF4, SLC24A4, NID1, and EDNRB) and skin cancer (e.g., TET2 and HERC2-OCA2). Work continues on highly prevalent but less studied skin conditions such as rosacea, acne, and atopic dermatitis. The NHS results have influenced public health policies on indoor tanning devices. Conclusions. The NHSs have provided invaluable resources on skin disease population science and contributed to the etiological understanding of multiple skin disorders. PMID:27459457

    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

    Full Text Available Soil salinity is one of the main environmental problems affecting extensive area in the world. There are some problems with traditional data collection methods for soil studies. Using the new methods and techniques such as remote sensing could overcome most of these problems. However using these data in areas with uncommon usages needed some researches to find the best calibration between the data and real situations in soil. This research was carried out using Landsat satellite images in Neyshabour area, North East of Iran. In order to prepare suitable learning samples for the image processing in this study, 300 locations were randomly selected in the area, among which 273 locations were finally selected as suitable surface soil samples. All samples were moved to laboratory and their electrical conductivity was measured. Six reflective bands of ETM+ satellite images taken from the study area in 2002 were used for the image processing analysis. Classification of different soil salinities was carried out using common algorithms of image classification based on the best composition bands and using statistical methods between soil salinity variables and digital numbers of the images to represent a suitable method. the research results showed that the reflective bands 7, 3, 4 and 1 are the best band composition for preparing the color composite images and for the classification of the salinity in this area. The highest coefficient of determination was R2=0.311 and R2=0.44 for saline and non-saline soil respectively using band 2 and 3 of the images at 5% significant level. Based on the results, it can be concluded that the potential of ETM+ images for delineation and identification of different soil salinity are limited.

  13. 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

    In urban cities, the environmental services are the responsibility of the public sector, where piped water supply is the norm for urban household. Likewise, in Beirut City (capital of Lebanon) official water authorities are the main supplier of domestic water through a network of piping system that leaks in many areas. Beirut City and its suburbs are overpopulated since it is the residence of 1/3 of the Lebanese citizens. Thus, Beirut suffers deficiency in meeting its water demand. Water rationing, as a remedial action, is firmly established since four decades by the Lebanese Water Authorities. Consumers resorted then to private wells to supplement their domestic water needs. Consequently, household water quality is influenced by external factors relating to well water characteristics and internal factors depending on the types of the pipes of the distribution network and cross connections to sewer pipes. These factors could result in chemical and microbial contamination of drinking water. The objective of this study is to investigate domestic water quality variation in Beirut City emerging form the aforementioned factors. The presented work encircles a typical case study of Beirut City (Ras Beirut). Results showed deterioration pattern in domestic water quality. The predicted metal species and scales within the water pipes of distribution network depended on water pH, hardness, sulfate, chloride, and iron. The corrosion of iron pipes mainly depended on Mg hardness.

    2003-12-01

    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 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.

    2006-03-01

    A structure is vulnerable if any small damage will trigger disproportionately large consequences, even leads to a cascade of failure events and progressive collapse. The structural vulnerability performance depends upon the properties, locations of damaged components and the way they are connected to the rest of the structure. In this paper, progressive failure analysis method is utilized for the vulnerability study of cable-stayed bridges. The goal of it is to identify various failure scenarios initiated from the sudden damage of some bridge components. Based on the analysis results, assuming that the behaviors of damaged components can be modeled using plastic hinges, the hybrid element model is introduced to derived the modified stiffness matrix considering both of the effects of bending moments and shear forces. Furthermore, the vulnerability index in terms of the nodal stiffness degradation can be analytically quantified, which could be regarded as an index to determine the bridge failure consequences, so that the vulnerability distribution graph for the whole bridge can be sketched to evaluate the bridge performances from vulnerability viewpoints. This quantitative approach is applicable for structural evaluation under unforeseen attack and illustrated on a typical long-span cable-stayed bridge.

    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.

    In general, reliable studies are well designed and well performed, and enough details on study design and performance are reported to assess the study. For hazard and risk assessment in various legal frameworks, many different types of ecotoxicity studies need to be evaluated for reliability. These studies vary in study design, methodology, quality, and level of detail reported (e.g., reviews, peer-reviewed research papers, or industry-sponsored studies documented under Good Laboratory Practice [GLP] guidelines). Regulators have the responsibility to make sound and verifiable decisions and should evaluate each study for reliability in accordance with scientific principles regardless of whether they were conducted in accordance with GLP and/or standardized methods. Thus, a systematic and transparent approach is needed to evaluate studies for reliability. In this paper, 8 different methods for reliability assessment were compared using a number of attributes: categorical versus numerical scoring methods, use of exclusion and critical criteria, weighting of criteria, whether methods are tested with case studies, domain of applicability, bias toward GLP studies, incorporation of standard guidelines in the evaluation method, number of criteria used, type of criteria considered, and availability of guidance material. Finally, some considerations are given on how to choose a suitable method for assessing reliability of ecotoxicity studies. Integr Environ Assess Manag. ©2016 SETAC.

  20. 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.

    2008-01-01

    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.

    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.

    Objective: While there is general agreement that patient education is essential for compliance, no objective tools exist to assess knowledge in children and parents of children with endocrine disorders. We aimed to design and validate a Pediatric Endocrine Knowledge Assessment Questionnaire (PEKAQ) for congenital hypothyroidism, Hashimoto’s thyroiditis, isolated growth hormone deficiency, Graves’ disease, and congenital adrenal hyperplasia. We evaluated baseline knowledge of children and parents of children with these disorders and assessed impact of educational intervention. Methods: At baseline, 77 children (12-18 years) and 162 parents of children 1-18 years participated in this prospective intervention study. Educational handouts for five targeted disorders were designed. Following one-on-one educational intervention, 55 children and 123 parents participated. Baseline and post-intervention knowledge scores were compared using McNemar’s test. Results: Adequate multi-rater Kappa measure of agreement was achieved for children’s (0.70) and parent’s (0.75) PEKAQs. Flesch Reading Ease Score for both PEKAQs (15 questions each) was 65. Post-intervention, significantly higher proportion of parents and children answered majority of questions correctly (pexercise and diet with these disorders, and long-term prognosis. Parent’s knowledge score was an independent predictor of child’s score. Conclusions: To our knowledge, this is the first validated PEKAQ that can be used widely in pediatric endocrinology clinics. We noted significant improvement in knowledge of children and parents of children with endocrine disorders. PMID:27353948

  12. Revision Vodcast Influence on Assessment Scores and Study Processes in Secondary Physics

    Science.gov (United States)

    Marencik, Joseph J.

    A quasi-experimental switching replications design with matched participants was employed to determine the influence of revision vodcasts, or video podcasts, on students' assessment scores and study processes in secondary physics. This study satisfied a need for quantitative results in the area of vodcast influence on students' learning processes. Thirty-eight physics students in an urban Ohio public high school participated in the study. The students in one Physics class were paired with students in another Physics class through the matching characteristics of current student cumulative test score mean and baseline study process as measured by the Study Process Questionnaire (SPQ). Students in both classes were given identical pedagogic treatment and access to traditional revision tools except for the supplemental revision vodcasts given to the experimental group. After students in the experimental group viewed the revision vodcast for a particular topic, the assessment scores of the students in the experimental group were compared to the assessment scores of the control group through the direct-difference, D, test to determine any difference between the assessment score means of each group. The SPQ was given at the beginning of the experiment and after each physics assessment. The direct-difference method was again used to determine any difference between the SPQ deep approach scores of each group. The SPQ was also used to determine any correlative effects between study process and revision vodcast use on students' assessment scores through descriptive statistics and an analysis of variance (ANOVA) test. Analysis indicated that revision vodcast use significantly increased students' assessment scores (p.05). There were no significant correlative effects of revision vodcast use and study processes on students' assessment scores (p>.05). This study offers educators the empirical support to devote the necessary effort, time, and resources into developing successful

    Chen, Weiyun; Mason, Steve; Hypnar, Andrew; Bennett, Austin

    2016-03-01

    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 pointsCATCH 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 physical

    2011-01-01

    Full Text Available his study is to investigate whether self-assessment contains construct- irrelevant variances of gender and age, and whether self-assessment correlates with test scores. The data were collected from seventy-eight newly arrived international students at the English Lan­guage Center, Michigan State University, USA. Prior to class com­mencement, they were asked to self-assess their listening, speaking, and interactive skill. Then, a test of listening was administered; finally, they were assigned to perform task-based conversational activities.The statistical findings imply that, firstly, gender and age do not provide construct irrelevant variances to the validity of self-assessment and, se­condly, self-assessment produces reliable scores.

    2008-01-01

    Undertaking assessment is a significant component of a Child Psychotherapist's work within Child and Adolescent Mental Health Services (CAMHS), yet as an activity it has been relatively neglected in the research literature. This study made use of a small-scale, qualitative design to explore the nature and function of psychoanalytic assessment work within a single CAMHS team. After an initial audit of child psychotherapy assessment work, indepth interviews with 5 Child and Adolescent Psychotherapists, exploring the nature of assessment work, were analysed using Interpretative Phenomenological Analysis (IPA). Results suggested that assessment is a major part of the Child Psychotherapist's work, although there are different types of assessment done in different contexts. Among the participants there was a certain shared understanding of the psychoanalytic approach to assessment, although with significant differences in regard to process, technique (e.g. use of interpretation, the role of countertransference) and the reporting of assessments. The analysis also suggested tensions between the role of the assessor as an 'expert' and as a 'therapist'.

    Becker, Madeline

    The purpose of the study was to assess if science learning could be determined by using written reflection and drawings in a science classroom of 5 th-grade Navajo students. The significance of this study was the understanding of the culture, assessments and learning of Navajo students. I studied a classroom on the Navajo reservation wherein 26 members of the class took part in science instruction complemented by using writing and drawing which were used as their assessments. The perceptions of the 8 students who were interviewed represent the case. In the study I profiled the 8 participants. Their culture, language, and views on assessment and learning were documented by their words. Their responses described their learning experiences. Assessments were seen as frustrating and limiting expression of what was known and damaging when not contributed to learning. Students explained that drawing enabled them to remember along with provoking vocabulary development. Student cultural knowledge was documented as valuable background experience contributing to learning within the classroom. Students viewed science as needing to be useful in their culture. Finally, they were also very candid that their teachers must first get to know them for meaningful learning to begin. Learning for students was reinforced through writing and drawing the lesson's activities. Further concept development was assisted utilizing metacognition and creative problem solving techniques of elaboration and fluency applied to the writing and drawings. Based on the findings of this study, recommendations were made for use of holistic means of assessing Navajo children in science where preferred learning styles along with cultural background need to be included in assessment protocols. Using new and better assessment techniques can directly impact how students document their learning as well as reveal how they acquire new knowledge.

    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.

    Many studies document the efficacy of psychotherapy for acute syndromes such as depression, but less is known about personality change in patients treated for personality pathology. The Shedler-Westen Assessment Procedure (SWAP-200; Westen & Shedler, 1999a, 1999b) is an assessment tool that measures a broad spectrum of personality constructs and is designed to bridge the gap between the clinical and empirical traditions in personality assessment. In this article, we demonstrate the use of the SWAP-200 as a measure of change in a case study of a patient diagnosed with borderline personality disorder. We collected assessment data at the start of treatment and after 2 years of psychotherapy. The findings illustrate the personality processes targeted in intensive psychotherapy for borderline personality.

    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.

  11. E-assessment of prior learning: a pilot study of interactive assessment of staff with no formal education who are working in Swedish elderly care

    2014-01-01

    Background The current paper presents a pilot study of interactive assessment using information and communication technology (ICT) to evaluate the knowledge, skills and abilities of staff with no formal education who are working in Swedish elderly care. Methods Theoretical and practical assessment methods were developed and used with simulated patients and computer-based tests to identify strengths and areas for personal development among staff with no formal education. Results Of the 157 staff with no formal education, 87 began the practical and/or theoretical assessments, and 63 completed both assessments. Several of the staff passed the practical assessments, except the morning hygiene assessment, where several failed. Other areas for staff development, i.e. where several failed (>50%), were the theoretical assessment of the learning objectives: Health, Oral care, Ergonomics, hygiene, esthetic, environmental, Rehabilitation, Assistive technology, Basic healthcare and Laws and organization. None of the staff passed all assessments. Number of years working in elderly care and staff age were not statistically significantly related to the total score of grades on the various learning objectives. Conclusion The interactive assessments were useful in assessing staff members’ practical and theoretical knowledge, skills, and abilities and in identifying areas in need of development. It is important that personnel who lack formal qualifications be clearly identified and given a chance to develop their competence through training, both theoretical and practical. The interactive e-assessment approach analyzed in the present pilot study could serve as a starting point. PMID:24742168

    2012-11-01

    Clinical reasoning is a core competence of doctors. Therefore, the assessment of clinical reasoning of undergraduate students is an important part of medical education. Three medical universities in the Netherlands wish to develop a shared question database in order to assess clinical reasoning of undergraduate students in Computer-Based Assessments (CBA). To determine suitable question types for this purpose a literature study was carried out. Search of ERIC and PubMed and subsequent cross referencing yielded 30 articles which met the inclusion criteria of a focus on question types suitable to assess clinical reasoning of medical students and providing recommendations for their use. Script Concordance Tests, Extended Matching Questions, Comprehensive Integrative Puzzles, Modified Essay Questions/Short Answer Questions, Long Menu Questions, Multiple Choice Questions, Multiple True/False Questions and Virtual Patients meet the above-mentioned criteria, but for different reasons not all types can be used easily in CBA. A combination of Comprehensive Integrative Puzzles and Extended Matching Questions seems to assess most aspects of clinical reasoning and these question types can be adapted for use in CBA. Regardless of the question type chosen, patient vignettes should be used as a standard stimulus format to assess clinical reasoning. Further research is necessary to ensure that the combination of these question types produces valid assessments and reliable test results.

    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.

  19. Worth it? Findings from a study of how academics assess students’ Web 2.0 activities

    Full Text Available Educational commentators have offered many pedagogical rationales for using Web 2.0 to support learning in higher education, and academics are being encouraged to find ways for their students to use social web technologies. Questions arise as to the value of these activities compared to more conventional assignments, and whether implementing such changes to student assessment is worth the effort. We conducted a survey of academics’ assessment of students’ Web 2.0 activities in Australian universities and found that this form of assessment is being conducted by a small number of academics, in a range of fields of study, but mainly in Humanities and Social Sciences, with varying kinds of intended and actual learning outcomes. Blogging and wiki-writing predominate, low and medium-stakes assessment are most common, and different methods of marking and feedback are in use. Qualitative feedback from the survey and follow-up interviews gave further insights into benefits and challenges of Web 2.0 assessment in relation to pedagogy, policy and practice. It appears that academics’ conservative approaches to conducting assessment and their novice approaches to utilising social web technologies are factors which seriously limit realising the potential of Web 2.0 for medium or high-stakes assessment.

    Although adequate assessment of exposure is needed in epidemiological studies among foundry workers, previous studies are often lacking in this aspect. We conducted a retrospective cohort study of a Chinese iron and steel company with a 14-yr follow up during 1980-1993. Exposure assessment was performed for a single job, i.e., the current job for the active worker and the longest job for the retired or deceased worker as of the end of the follow-up, which was allocated as the surrogate of lifetime job and was applied to a job-exposure matrix. Of the 147,062 cohort members, 52,394 males (43%) and 5,291 females (21%) were exposed to any of 15 hazardous factors such as dust, silica, PAHs (polycyclic aromatic hydrocarbons), CO (carbon monoxide) and heat. In 2,104 randomly selected samples, the exposure assessment of exposed workers based on a single job was found to be 12-14% lower than the real situation. This study suggests that the exposure assessment is valuable in evaluating the health effects among the foundry workers, despite some limitations such as underestimation of exposure assessment and the lack of data regarding smoking and drinking habits.

  2. Establishing Normative Values for the Barnett Balance Assessment Tool: A Preliminary Study

    2014-04-01

    Full Text Available The purpose of this study was to establish normative data for the Barnett Balance Assessment (BBA for individuals ages 18-70+ years. The BBA is a newly developed assessment tool that may address limitations present in other assessments currently used to detect balance deficits. 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.

    Oil and gas well drilling activities are associated with numerous hazards which have the potential to cause injury or harm for people, property and the environment. These hazards are also a threat for the reputation of drilling companies. To prevent accidents and undesired events in drilling operations it is essential to identify, evaluate, assess and control the attendant risks. In this work, a structured methodology is proposed for risk assessment of drilling activities. A case study is performed to identify, analyze and assess the risks arising from human factors in one of the on shore drilling sites in southern Iran. A total of 17 major hazards were identified and analyzed using the proposed methodology. The results showed that the residual risks of 100% of these hazards were in the acceptable or transitional zone, and their levels were expected to be lowered further by proper controls. This structured methodology may also be used in other drilling sites and companies for assessing the risks.

  5. 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

    2014-01-01

    Wearable EEG systems for continuous brain monitoring is an emergent technology that involves significant technical challenges. Some of these are related to the fact that these systems operate in conditions that are far less controllable with respect to interference and artifacts than is the case for conventional systems. Quantitative assessment of artifacts provides a mean for optimization with respect to electrode technology, electrode location, electronic instrumentation and system design. To this end, we propose an artifact assessment method and evaluate it over an empirical study of 3 subjects and 5 different types of artifacts. The study showed consistent results across subjects and artifacts.

    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)

    Little is known about the bioavailability of heavy metal contamination and its health risks after rice ingestion. This study aimed to determine bioavailability of heavy metal (As, Cd, Cu, Cr, Co, Al, Fe, Zn and Pb) concentrations in cooked rice and human Health Risk Assessment (HRA). The results found Zn was the highest (4.3±0.1 mg/kg), whereas As showed the lowest (0.015±0.001 mg/kg) bioavailability of heavy metal concentration in 22 varieties of cooked rice. For single heavy metal exposure, no potential of non carcinogenic health risks was found, while carcinogenic health risks were found only for As. Combined heavy metal exposures found that total Hazard Quotient (HQtotal) values for adult were higher than the acceptable range (HQTotal1×10(-4)) for both adult and children. This study is done to understand that the inclusion of bioavailability heavy metal into HRA produces a more realistic estimation of human heavy metal exposure.

    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.

  14. What is Learned from Longitudinal Studies of Advertising and Youth Drinking and Smoking? A Critical Assessment

    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.

    2008-05-01

    Full Text Available Abstract Background Several thousand human genome epidemiology association studies are published every year investigating the relationship between common genetic variants and diverse phenotypes. Transparent reporting of study methods and results allows readers to better assess the validity of study findings. Here, we document reporting practices of human genome epidemiology studies. Methods Articles were randomly selected from a continuously updated database of human genome epidemiology association studies to be representative of genetic epidemiology literature. The main analysis evaluated 315 articles published in 2001–2003. For a comparative update, we evaluated 28 more recent articles published in 2006, focusing on issues that were poorly reported in 2001–2003. Results During both time periods, most studies comprised relatively small study populations and examined one or more genetic variants within a single gene. Articles were inconsistent in reporting the data needed to assess selection bias and the methods used to minimize misclassification (of the genotype, outcome, and environmental exposure or to identify population stratification. Statistical power, the use of unrelated study participants, and the use of replicate samples were reported more often in articles published during 2006 when compared with the earlier sample. Conclusion We conclude that many items needed to assess error and bias in human genome epidemiology association studies are not consistently reported. Although some improvements were seen over time, reporting guidelines and online supplemental material may help enhance the transparency of this literature.

    2009-01-01

    The 8.0 Mw Wenchuan earthquake triggered widespread and large scale landslides in mountainous regions.An approach was used to map and assess landslide susceptibility in a given area. A numerical rating system was applied to five factors that contribute to slope instability. Factors such as lithology, topography, streams and faults have an important influence as event-controlling factors for landslide susceptibility assessment. A final map is provided to show areas of low,medium, and high landslide susceptibility. Areas identified as having high landslide susceptibility were located in the central,northeastern, and far south regions of the study area. The assessment results will help decision makers to select safe sites for emergency placement of refuges and plan for future reconstruction. The maps may also be used as a basis for landslide risk management in the study area.

  4. Bayesian hierarchical models combining different study types and adjusting for covariate imbalances: a simulation study to assess model performance.

    Directory of Open Access Journals (Sweden)

    C Elizabeth McCarron

    Full Text Available BACKGROUND: Bayesian hierarchical models have been proposed to combine evidence from different types of study designs. However, when combining evidence from randomised and non-randomised controlled studies, imbalances in patient characteristics between study arms may bias the results. The objective of this study was to assess the performance of a proposed Bayesian approach to adjust for imbalances in patient level covariates when combining evidence from both types of study designs. METHODOLOGY/PRINCIPAL FINDINGS: Simulation techniques, in which the truth is known, were used to generate sets of data for randomised and non-randomised studies. Covariate imbalances between study arms were introduced in the non-randomised studies. The performance of the Bayesian hierarchical model adjusted for imbalances was assessed in terms of bias. The data were also modelled using three other Bayesian approaches for synthesising evidence from randomised and non-randomised studies. The simulations considered six scenarios aimed at assessing the sensitivity of the results to changes in the impact of the imbalances and the relative number and size of studies of each type. For all six scenarios considered, the Bayesian hierarchical model adjusted for differences within studies gave results that were unbiased and closest to the true value compared to the other models. CONCLUSIONS/SIGNIFICANCE: Where informed health care decision making requires the synthesis of evidence from randomised and non-randomised study designs, the proposed hierarchical Bayesian method adjusted for differences in patient characteristics between study arms may facilitate the optimal use of all available evidence leading to unbiased results compared to unadjusted analyses.

    2011-01-01

    This pilot study examined the use of a touch-screen tablet personal computer to assess smoking and alcohol use among low-income primary care patients (N = 100) and tested cross-method consistency with a paper assessment. Data were collected in 2009. A touch-screen survey assessed smoking, alcohol use, partner smoking, and acceptability. A separate paper survey assessed smoking, partner smoking, and acceptability. The touch-screen assessment was highly acceptable and reliable. Implications and limitations are noted. Future research should explore the use of touch-screen technology for clinical endeavors requiring a quick assessment of substance use. There was no outside funding for this study.

    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.

    Burden of disease (BoD) studies aim to identify the public health impact of different health problems and risk factors. To assess BoD, detailed knowledge is needed on epidemiology, disability and mortality in the population under study. This is particularly challenging for foodborne disease, because of the multitude of causative agents and their health effects. The purpose of this study is to systematically review the methodology of foodborne BoD studies. Three key questions were addressed: 1) which data sources and approaches were used to assess mortality, morbidity and disability?, 2) which methodological choices were made to calculate Disability Adjusted Life Years (DALY), and 3) were uncertainty analyses performed and if so, how? Studies (1990-June 2012) in international peer-reviewed journals and grey literature were identified with main inclusion criteria being that the study assessed disability adjusted life years related to foodborne disease. Twenty-four studies met our inclusion criteria. To assess incidence or prevalence of foodborne disease in the population, four approaches could be distinguished, each using a different data source as a starting point, namely 1) laboratory-confirmed cases, 2) cohort or cross-sectional data, 3) syndrome surveillance data and 4) exposure data. Considerable variation existed in BoD methodology (e.g. disability weights, discounting, age-weighting). Almost all studies analyzed the effect of uncertainty as a result of possible imprecision in the parameter values. Awareness of epidemiological and methodological rigor between foodborne BoD studies using the DALY approach is a critical priority for advancing burden of disease studies. Harmonization of methodology that is used and of modeling techniques and high quality data can enlarge the detection of real variation in DALY outcomes between pathogens, between populations or over time. This harmonization can be achieved by identifying substantial data gaps and uncertainty and

    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.

  10. The human component of sustainability: a study for assessing "human performances" of energy efficient construction blocks.

    Attaianese, Erminia; Duca, Gabriella

    2012-01-01

    This paper presents an applied research aimed at understanding the relevance and the applicability of human related criteria in sustainability assessment of construction materials. Under a theoretical perspective, human factors consideration is strongly encouraged by building sustainability assessment methods, but the practice demonstrates that current models for building sustainability assessment neglect ergonomic issues, especially those ones concerning the construction phase. The study starts from the observation that new construction techniques for high energy efficient external walls are characterized by elements generally heavier and bigger than traditional materials. In this case, high sustainability performances connected with energy saving could be reached only consuming high, and then not very much sustainable, human efforts during setting-up operations. The paper illustrates a practical approach for encompassing human factors in sustainability assessment of four block types for energy efficient external walls. Research steps, from block selections to bricklaying task analysis, human factors indicators and metrics formulation, data gathering and final assessment are going to be presented. Finally, open issues and further possible generalizations from the particular case study will be discussed.

    2011-10-01

    Although many aspects of environmental accounting methodologies in food production have already been investigated, the application of environmental indicators in the fruit sector is still rare and no consensus can be found on the preferred method. On the contrary, widely diverging approaches have been taken to several aspects of the analyses, such as data collection, handling of scaling issues, and goal and scope definition. This paper reviews studies assessing the sustainability or environmental impacts of fruit production under different conditions and identifies aspects of fruit production that are of environmental importance. Four environmental assessment methods which may be applied to assess fruit production systems are evaluated, namely Life Cycle Assessment, Ecological Footprint Analysis, Emergy Analysis and Energy Balance. In the 22 peer-reviewed journal articles and two conference articles applying one of these methods in the fruit sector that were included in this review, a total of 26 applications of environmental impact assessment methods are described. These applications differ concerning e.g. overall objective, set of environmental issues considered, definition of system boundaries and calculation algorithms. Due to the relatively high variability in study cases and approaches, it was not possible to identify any one method as being better than the others. However, remarks on methodologies and suggestions for standardisation are given and the environmental burdens of fruit systems are highlighted.

    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.

    This paper presents the inclusion of new, relevant impact categories for agriculture life cycle assessments. We performed a specific case study with a focus on the applicability of spatially explicit characterization factors. The main goals were to provide a detailed evaluation of these new impact category methods, compare the results with commonly used methods (ReCiPe and USEtox) and demonstrate how these new methods can help improve environmental assessment in agriculture. As an overall conclusion, the newly developed impact categories helped fill the most important gaps related to land use, water consumption, pesticide toxicity, and nontoxic emissions linked to fertilizer use. We also found that including biodiversity damage due to land use and the effect of water consumption on wetlands represented a scientific advance toward more realistic environmental assessment of agricultural practices. Likewise, the dynamic crop model for assessing human toxicity from pesticide residue in food can lead to better practice in pesticide application. In further life cycle assessment (LCA) method developments, common end point units and normalization units should be agreed upon to make it possible to compare different impacts and methods. In addition, the application of site-specific characterization factors allowed us to be more accurate regarding inventory data and to identify precisely where background flows acquire high relevance.

    2012-07-01

    Full Text Available Abstract Background Alcohol causes huge problems for population health and for society, which require interventions with individuals as well as populations to prevent and reduce harms. Brief interventions can be effective and increasingly take advantage of the internet to reach high-risk groups such as students. The research literature on the effectiveness of online interventions is developing rapidly and is confronted by methodological challenges common to other areas of e-health including attrition and assessment reactivity and in the design of control conditions. Methods/design The study aim is to evaluate the effectiveness of a brief online intervention, employing a randomized controlled trial (RCT design that takes account of baseline assessment reactivity, and other possible effects of the research process. Outcomes will be evaluated after 3 months both among student populations as a whole including for a randomized no contact control group and among those who are risky drinkers randomized to brief assessment and feedback (routine practice or to brief assessment only. A three-arm parallel groups trial will also allow exploration of the magnitude of the feedback and assessment component effects. The trial will be undertaken simultaneously in 2 universities randomizing approximately 15,300 students who will all be blinded to trial participation. All participants will be offered routine practice intervention at the end of the study. Discussion This trial informs the development of routine service delivery in Swedish universities and more broadly contributes a new approach to the study of the effectiveness of online interventions in student populations, with relevance to behaviors other than alcohol consumption. The use of blinding and deception in this study raise ethical issues that warrant further attention. Trial registration ISRCTN28328154

  20. Comparative assessment of predictions in ungauged basins – Part 2: Flood and low flow studies

    Directory of Open Access Journals (Sweden)

    J. L. Salinas

    2013-07-01

    Full Text Available The objective of this paper is to assess the performance of methods that predict low flows and flood runoff in ungauged catchments. The aim is to learn from the similarities and differences between catchments in different places, and to interpret the differences in performance in terms of the underlying climate-landscape controls. The assessment is performed at two levels. The Level 1 assessment is a meta-analysis of 14 low flow prediction studies reported in the literature involving 3112 catchments, and 20 flood prediction studies involving 3023 catchments. The Level 2 assessment consists of a more focused and detailed analysis of individual basins from selected studies from Level 1 in terms of how the leave-one-out cross-validation performance depends on climate and catchment characteristics as well as on the regionalisation method. The results indicate that both flood and low flow predictions in ungauged catchments tend to be less accurate in arid than in humid climates and more accurate in large than in small catchments. There is also a tendency towards a somewhat lower performance of regressions than other methods in those studies that apply different methods in the same region, while geostatistical methods tend to perform better than other methods. Of the various flood regionalisation approaches, index methods show significantly lower performance in arid catchments than regression methods or geostatistical methods. For low flow regionalisation, regional regressions are generally better than global regressions.

    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.

    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.

    School violence has increased over the past decade and innovative, sensitive, and standardized approaches to assess school violence risk are needed. In our current feasibility study, we initialized a standardized, sensitive, and rapid school violence risk approach with manual annotation. Manual annotation is the process of analyzing a student's transcribed interview to extract relevant information (e.g., key words) to school violence risk levels that are associated with students' behaviors, attitudes, feelings, use of technology (social media and video games), and other activities. In this feasibility study, we first implemented school violence risk assessments to evaluate risk levels by interviewing the student and parent separately at the school or the hospital to complete our novel school safety scales. We completed 25 risk assessments, resulting in 25 transcribed interviews of 12-18 year olds from 15 schools in Ohio and Kentucky. We then analyzed structured professional judgments, language, and patterns associated with school violence risk levels by using manual annotation and statistical methodology. To analyze the student interviews, we initiated the development of an annotation guideline to extract key information that is associated with students' behaviors, attitudes, feelings, use of technology and other activities. Statistical analysis was applied to associate the significant categories with students' risk levels to identify key factors which will help with developing action steps to reduce risk. In a future study, we plan to recruit more subjects in order to fully develop the manual annotation which will result in a more standardized and sensitive approach to school violence assessments.

    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.

    Ecological Risk Assessment (ERA) of GMO is basically identical to ERA of chemical substances, when it comes to assessing specific effects of the GMO plant material on the soil ecosystem. The tiered approach always includes the option of studying more complex but still realistic ecosystem level...... effects in 2nd tier caged experimental systems, cf. the new GMO ERA guidance: EFSA Journal 2010; 8(11):1879. We propose to perform a trophic structure analysis, TSA, and include the trophic structure as an ecological endpoint to gain more direct insight into the change in interactions between species, i.......e. the food-web structure, instead of relying only on the indirect evidence from population abundances. The approach was applied for effect assessment in the agro-ecosystem where we combined factors of elevated CO2, viz. global climate change, and GMO plant effects.

    2014-04-01

    Full Text Available 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.

    Visual pursuit is a key marker of residual consciousness in patients with disorders of consciousness (DOC). Currently, its assessment relies on subjective clinical decisions. In this study, we explore the variability of such clinical assessments, and present an easy-to-use device composed of cameras and video processing algorithms that could help the clinician to improve the detection of visual pursuit in a clinical context. Visual pursuit was assessed by an experienced research neuropsychologist on 31 patients with DOC and on 23 healthy subjects, while the device was used to simultaneously record videos of both one eye and the mirror. These videos were then scored by three researchers: the experienced research neuropsychologist who did the clinical assessment, another experienced research neuropsychologist, and a neurologist. For each video, a consensus was decided between the three persons, and used as the gold standard of the presence or absence of visual pursuit. Almost 10% of the patients were misclassified at the bedside according to their consensus. An automatic classifier analyzed eye and mirror trajectories, and was able to identify patients and healthy subjects with visual pursuit, in total agreement with the consensus on video. In conclusion, our device can be used easily in patients with DOC while respecting the current guidelines of visual pursuit assessment. Our results suggest that our material and our classification method can identify patients with visual pursuit, as well as the three researchers based on video recordings can.

  19. Importance of hydrological uncertainty assessment methods in climate change impact studies

    Science.gov (United States)

    Honti, M.; Scheidegger, A.; Stamm, C.

    2014-01-01

    Climate change impact assessments have become more and more popular in hydrology since the middle 1980's with a recent boost after the publication of the IPCC AR4 report. During hundreds of impact studies a quasi-standard methodology emerged, which is mainly shaped by the growing public demand for predicting how water resources management or flood protection should change in the following decades. The "standard" workflow relies on a model cascade from global circulation model (GCM) predictions for selected IPCC scenarios to future catchment hydrology. Uncertainty is present at each level and propagates through the model cascade. There is an emerging consensus between many studies on the relative importance of the different uncertainty sources. The prevailing perception is that GCM uncertainty dominates hydrological impact studies. Our hypothesis was that the relative importance of climatic and hydrologic uncertainty is (among other factors) heavily influenced by the uncertainty assessment method. To test this we carried out a climate change impact assessment and estimated the relative importance of the uncertainty sources. The study was performed on two small catchments in the Swiss Plateau with a lumped conceptual rainfall runoff model. In the climatic part we applied the standard ensemble approach to quantify uncertainty but in hydrology we used formal Bayesian uncertainty assessment with two different likelihood functions. One was a time-series error model that was able to deal with the complicated statistical properties of hydrological model residuals. The second was an approximate likelihood function for the flow quantiles. The results showed that the expected climatic impact on flow quantiles was small compared to prediction uncertainty. The source, structure and composition of uncertainty depended strongly on the uncertainty assessment method. This demonstrated that one could arrive to rather different conclusions about predictive uncertainty for the same

    Climate change impact assessments have become more and more popular in hydrology since the middle 1980s with a recent boost after the publication of the IPCC AR4 report. From hundreds of impact studies a quasi-standard methodology has emerged, to a large extent shaped by the growing public demand for predicting how water resources management or flood protection should change in the coming decades.

    Full Text Available Context: Deficits in social skills may present in a range of psychiatric disorders, particularly in the more serious and persistent conditions, and have an influence on functioning across various domains. Aims: This pilot study aimed at developing a brief measure, for structured evaluation and screening for social skills deficits, which can be easily integrated into routine clinical practice. Settings and Design: The sample consisted of 380 inpatients and their accompanying caregivers, referred to Psychiatric Rehabilitation Services at a tertiary care government psychiatric hospital. Materials and Methods: The evaluation included an Inpatient intake Proforma and the 20-item Social Skills Assessment Screening Scale (SSASS. Disability was assessed using the Indian Disability Evaluation and Assessment Scale (IDEAS for a subset of 94 inpatients. Statistical Analysis Used: The analysis included means and standard deviations, frequency and percentages, Cronbach's alpha to assess internal consistency, t-tests to assess differences in social skills deficits between select subgroups, and correlation between SSASS and IDEAS scores. Results: The results indicated the profile of social skills deficits assessed among the inpatients with varied psychiatric diagnoses. The “psychosis” group exhibited significantly higher deficits than the “mood disorder” group. Results indicated high internal consistency of the SSASS and adequate criterion validity demonstrated by correlations with select IDEAS domains. Modifications were made to the SSASS following the pilot study. Conclusions: The SSASS has potential value as a measure for screening and individualised intervention plans for social skills training in mental health and rehabilitation settings. The implications for future work on the psychometric properties and clinical applications are discussed.

  3. A Review of Exposure Assessment Methods in Epidemiological Studies on Incinerators

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Incineration is a common technology for waste disposal, and there is public concern for the health impact deriving from incinerators. Poor exposure assessment has been claimed as one of the main causes of inconsistency in the epidemiological literature. We reviewed 41 studies on incinerators published between 1984 and January 2013 and classified them on the basis of exposure assessment approach. Moreover, we performed a simulation study to explore how the different exposure metrics may influence the exposure levels used in epidemiological studies. 19 studies used linear distance as a measure of exposure to incinerators, 11 studies atmospheric dispersion models, and the remaining 11 studies a qualitative variable such as presence/absence of the source. All reviewed studies utilized residence as a proxy for population exposure, although residence location was evaluated with different precision (e.g., municipality, census block, or exact address. Only one study reconstructed temporal variability in exposure. Our simulation study showed a notable degree of exposure misclassification caused by the use of distance compared to dispersion modelling. We suggest that future studies (i make full use of pollution dispersion models; (ii localize population on a fine-scale; and (iii explicitly account for the presence of potential environmental and socioeconomic confounding.

  4. The changing assessments of John Snow's and William Farr's cholera studies.

    Science.gov (United States)

    Eyler, J M

    2001-01-01

    This article describes the epidemiological studies of cholera by two major British investigators of the mid-nineteenth century, John Snow and William Farr, and it asks why the assessments of their results by contemporaries was the reverse of our assessment today. In the 1840s and 1850s Farr's work was considered definitive, while Snow's was regarded as ingenious but flawed. Although Snow's conclusions ran contrary to the exceptations of his contemporaries, the major reservations about his cholera studies concerned his bold use of analogy, his thoroughgoing reductionism, and his willingness to ignore what seemed to be contrary evidence. Farr's electric use of current theories, his reliance multiple causation, and his discovery of a mathematical law to describe the outbreak in London in 1849 was much more convincing to his contemporaries. A major change in thinking about disease causation was needed before Snow's work could be widely accepted. William Farr's later studies contributed to that acceptance.

  5. The studies of phase equilibria and efficiency assessment for self-emulsifying lipid-based formulations.

    2012-06-01

    The study was designed to build up a database for the evaluation of the self-emulsifying lipid formulations performance. A standard assessment method was constructed to evaluate the self-emulsifying efficiency of the formulations based on five parameters including excipients miscibility, spontaneity, dispersibility, homogeneity, and physical appearance. Equilibrium phase studies were conducted to investigate the phase changes of the anhydrous formulation in response to aqueous dilution. Droplet size studies were carried out to assess the influence of lipid and surfactant portions on the resulted droplet size upon aqueous dilution. Formulations containing mixed glycerides showed enhanced self-emulsification with both lipophilic and hydrophilic surfactants. Increasing the polarity of the lipid portion in the formulation leaded to progressive water solubilization capacity. In addition, formulations containing medium chain mixed glycerides and hydrophilic surfactants showed lower droplet size compared with their long chain and lipophilic counterparts.

    In 2003, the QUADAS tool for systematic reviews of diagnostic accuracy studies was developed. Experience, anecdotal reports, and feedback suggested areas for improvement; therefore, QUADAS-2 was developed. This tool comprises 4 domains: patient selection, index test, reference standard, and flow and timing. Each domain is assessed in terms of risk of bias, and the first 3 domains are also assessed in terms of concerns regarding applicability. Signalling questions are included to help judge risk of bias. The QUADAS-2 tool is applied in 4 phases: summarize the review question, tailor the tool and produce review-specific guidance, construct a flow diagram for the primary study, and judge bias and applicability. This tool will allow for more transparent rating of bias and applicability of primary diagnostic accuracy studies.

    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.

    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.

    Full Text Available Accurate assessment of obsessions and compulsions is a crucial step in treatment planning for Obsessive-Compulsive Disorder (OCD. In this pilot study, we sought to determine if the use of Ecological Momentary Assessment (EMA could provide additional symptom information beyond that captured during standard assessment of OCD. We studied three adults diagnosed with OCD and compared the number and types of obsessions and compulsions captured using the Yale-Brown Obsessive-compulsive Scale (Y-BOCS compared to EMA. Following completion of the Y-BOCS interview, participants then recorded their OCD symptoms into a digital voice recorder across a twelve-hour period in reply to randomly sent mobile phone SMS prompts. The EMA approach yielded a lower number of symptoms of obsessions and compulsions than the Y-BOCS but produced additional types of obsessions and compulsions not identified by the Y-BOCS. We conclude that the EMA-OCD procedure may represent a worthy addition to the suite of assessment tools used when working with clients who have OCD. Further research with larger samples is required to strengthen this conclusion.

    The goals of this quasi-experimental pilot study were to test an assessment tool designed to evaluate students' teamwork skills, and to assess the effectiveness of an interprofessional education (IPE) course. Participants were health professional students (physical therapy, pharmacy, dental and osteopathic medicine), 24 of whom were second-year students who had previously taken part in an IPE course (experimental group), and 22 of whom were third years that had not (control group). Students interacted with a standardized patient and her son during an asynchronous Team Objective Structured Clinical Exam (TOSCE), after which they were scored on their teamwork skills using newly designed teamwork rating scales. Cronbach Alpha calculations suggest that the rating scales are reliable when rater scores are aggregated (0.81). Pearson coefficient calculations determined that teamwork scores of live raters and video raters were significantly correlated (p teamwork skills. The results of this study contribute to the much needed IPE assessment literature, and suggest that teamwork skills can be taught and effectively assessed using this new rating scale.

    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.

  16. Epidemiologic evidence for chloroprene carcinogenicity: review of study quality and its application to risk assessment.

    Bukowski, John Arthur

    2009-09-01

    This article evaluates the quality and weight of evidence associated with epidemiologic studies of cancer among occupational cohorts exposed to chloroprene. The focus is on liver, lung, and lymphohematopoietic cancers, which had been increased in early studies. Literature searches identified eight morbidity/mortality studies covering seven chloroprene-exposed cohorts from six countries. These studies were summarized and their quality was assessed using the 10 criteria suggested by the U.S. Environmental Protection Agency. The limitations within this literature (primarily the early studies) included crude exposure assessment, incomplete follow-up, uncertain baseline rates, and uncontrolled confounding by factors such as smoking, drinking, and co-exposure to benzene and vinyl chloride. Four cohorts were studied by the same group of investigators, who reported no overall increased associations for any cancers. This four-cohort study was by far the most rigorous, having the most comprehensive exposure assessment and follow-up and the most detailed documentation. This study also contained the two largest cohorts, including an American cohort from Louisville, Kentucky, that ranked at or near the top for each of the 10 quality criteria. There was evidence of a strong healthy worker effect in the four-cohort study, which could have hidden small excess risks. Small increased risks were suggested by internal or company-specific analyses, but these were most likely caused by uncontrolled confounding and low baseline rates. Overall, the weight of evidence does not support any substantial link between chloroprene exposure and cancer, but inconsistencies and a lack of control for major confounders preclude drawing firmer conclusions.

    Full Text Available Identify every paediatric surgical article published in 1998 and every paediatric surgical article published in 2013, and determine which study designs were used and whether they were appropriate for robustly assessing interventions in surgical conditions.A systematic review was conducted according to a pre-specified protocol (CRD42014007629, using EMBASE and Medline. Non-English language studies were excluded. Studies were included if meeting population criteria and either condition or intervention criteria.Children under the age of 18, or adults who underwent intervention for a condition managed by paediatric surgeons when they were under 18 years of age.One managed by general paediatric surgeons.Used for treatment of a condition managed by general paediatric surgeons.Studies were classified according to whether the IDEAL collaboration recommended their design for assessing surgical interventions or not. 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.

    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.

  2. Scenario-neutral Food Security Risk Assessment: A livestock Heat Stress Case Study

    2015-12-01

    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

  3. Assessment of learning, memory and attention in developmental neurotoxicity regulatory studies: Introduction.

    Science.gov (United States)

    Makris, Susan L; Vorhees, Charles V

    2015-01-01

    There are a variety of chemicals, including pharmaceuticals, that alter neurobehavior following developmental exposure and guidelines for the conduct of studies to detect such effects by statute in the United States and Europe. Guidelines for Developmental Neurotoxicity Testing (DNT) studies issued by the U.S. Environmental Protection Agency (EPA) under prevailing law and European Organization for Economic Cooperation and Development (OECD) recommendations to member countries provide that such studies include a series of neurobehavioral and neuropathological assessments. Among these are assessment of cognitive function, specifically learning and memory. After reviewing 69 DNT studies submitted to the EPA, tests of learning and memory were noted to have detected the lowest observed adverse effect level (LOAELs) less frequently than behavioral tests of locomotor activity and acoustic/auditory startle, but slightly more than for the developmental Functional Observational Battery (devFOB; which is less extensive than the full FOB), but the reasons for the lower LOAEL detection rate for learning and memory assessment could not be determined. A major concern identified in the review, however, was the adequacy of the methods employed in these studies rather than on the importance of learning and memory to the proper assessment of brain function. Accordingly, a symposium was conducted to consider how the guidelines for tests of learning and memory might be improved. Four laboratories with established histories investigating the effects of chemical exposures during development on learning, memory, and attention, were invited to review the topic and offer recommendations, both theoretical and practical, on approaches to improve the assessment of these vital CNS functions. Reviewers were asked to recommend methods that are grounded in functional importance to CNS integrity, well-validated, reliable, and amenable to the context of regulatory studies as well as to basic

    2013-01-01

    The objective of the present review was to examine how predictive validity is analyzed and reported in studies of instruments used to assess violence risk. We reviewed 47 predictive validity studies published between 1990 and 2011 of 25 instruments that were included in two recent systematic reviews. Although all studies reported receiver operating characteristic curve analyses and the area under the curve (AUC) performance indicator, this methodology was defined inconsistently and findings often were misinterpreted. In addition, there was between-study variation in benchmarks used to determine whether AUCs were small, moderate, or large in magnitude. Though virtually all of the included instruments were designed to produce categorical estimates of risk - through the use of either actuarial risk bins or structured professional judgments - only a minority of studies calculated performance indicators for these categorical estimates. In addition to AUCs, other performance indicators, such as correlation coefficients, were reported in 60% of studies, but were infrequently defined or interpreted. An investigation of sources of heterogeneity did not reveal significant variation in reporting practices as a function of risk assessment approach (actuarial vs. structured professional judgment), study authorship, geographic location, type of journal (general vs. specialized audience), sample size, or year of publication. Findings suggest a need for standardization of predictive validity reporting to improve comparison across studies and instruments.

    Neuropsychological impairments (NPI) can lead to difficulties in daily functioning and ultimately contribute to poor health outcomes. However, evidence for the feasibility of NPI assessment in resource-limited settings using tests developed in high literacy/high education cultures is sparse. The main objectives were to: (1) determine the feasibility and appropriateness of conducting neuropsychological assessments among a migrant farm worker population in Baja California, Mexico and (2) preliminary describe neuropsychological test performance in this unique population. A neuropsychological test battery was administered to 21 presumably healthy adults (8 men, 13 women) during a two-day international health services and research collaboration. All but one neuropsychological test (i.e. figure learning) was feasible and appropriate to administer to the study population. Contrary to expectations, participants performed better on verbal rather than nonverbal neuropsychological tests. Results support inclusion of neuropsychological tests into future studies among migrant farm worker populations in Baja California, Mexico.

    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)

    2007-01-01

    Because of the lack of existing information needed to evaluate the risks from inhalation exposures to depleted uranium (DU) aerosols of US soldiers during the 1991 Persian Gulf War, the US Department of Defense funded an experimental study to measure the characteristics of DU aerosols created when Abrams tanks and Bradley fighting vehicles are struck with large-caliber DU penetrators, and a dose and risk assessment for individuals present in such vehicles. This paper describes some of the difficulties experienced in dose assessment modelling of the very complex DU aerosols created in the Capstone studies, e.g. high concentrations, heterogeneous aerosol properties, non-lognormal particle size distributions, triphasic in vitro dissolution and rapid time-varying functions of both DU air concentration and particle size. The approaches used to solve these problems along with example results are presented.

    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.

    The blueprints for the assessment, treatment, and future study of catatonia in autism spectrum disorders (ASDs), which are submitted in this chapter aim to increase early recognition and treatment of catatonia in ASDs, show the urgency of controlled treatment trials, and increase collaborative and interdisciplinary research into the co-occurrence of these two enigmatic disorders. Catatonia should be assessed in any patient with ASDs when there is an obvious and marked deterioration in movement, pattern of activities, self-care, and practical skills, compared with previous levels, through a comprehensive diagnostic evaluation of medical and psychiatric symptoms. A formal diagnosis should be ascertained using ASD specific criteria for catatonia that takes into account baseline symptoms like muteness, echophenomena, stereotypy, negativism, or other psychomotor abnormalities. Any underlying medical and neurological conditions should be treated, and culprit medications or other substances that may cause catatonia should be eliminated. Separate treatment blueprints are presented for mild, moderate, and severe catatonia, featuring combinations of a psychological approach developed by Shah and Wing and medical treatments that have shown efficacy in catatonia: lorazepam challenge, lorazepam trial, lorazepam continuation, and bilateral electroconvulsive therapy (ECT). These treatment modalities in themselves are well established. Side effects and complications are known and manageable. Legal, ethical, and practice guidelines governing all treatment aspects should be followed. The treatment blueprints should be viewed as best estimates pending future controlled studies. The blueprint for the future study of catatonia in ASDs describes promising clinical and preclinical research avenues. Longitudinal studies need to assess the possible effect of early recognition and adequate treatment of catatonia in ASDs in order to avoid the impairment associated with chronicity. Effects of

    Full Text Available Abstract Background The Perineal Assessment and Repair Longitudinal Study (PEARLS is a national clinical quality improvement initiative designed to improve the assessment and management of perineal trauma. Perineal trauma affects around 85% of women who have a vaginal birth in the UK each year and millions more world-wide. Continuous suturing techniques compared with traditional interrupted methods are more effective in reducing pain and postnatal morbidity, however they are not widely used by clinicians despite recommendations of evidence based national clinical guidelines. Perineal suturing skills and postnatal management of trauma remain highly variable within and between maternity units in the UK as well as worldwide. Implementation of a standardised training package to support effective perineal management practices could reduce perineal pain and other related postnatal morbidity for a substantial number of women. Methods/Design PEARLS is a matched pair cluster trial, which is being conducted in maternity units across the UK. Units within a matched pair will be randomised to implement the study intervention either early or late in the study period. The intervention will include the cascading of a multi-professional training package to enhance midwifery and obstetric skills in the assessment, repair and postnatal management of perineal trauma. Women who have had an episiotomy or second degree perineal tear will be eligible for recruitment. Prior to developing the intervention and deciding on study outcomes, a Delphi survey and a consensus conference were held to identify what women, who previously suffered perineal trauma during childbirth, considered to be important outcomes for them. Findings from this preliminary work (which will be reported elsewhere and other outcomes including women's experiences of perineal pain and pain on activity, breastfeeding uptake and duration and psychological well-being as assessed using the Edinburgh

    Full Text Available The objective of this study was to assess the role of motivation on teacher performance in Indonesia. This study in an assessment of this aim used deductive approach where a qualitative survey was conducted among students at Universitas Negeri Medan (UNIMED, Indonesia who are assumed to be future teachers. The survey was intended to get their responses on what they feel are the best factors that could motivate them as future teachers among a list of ten motivational factors. In the light of this the study sets to identify the most ranked factors among the ten motivational factors. The analysis from the empirical findings showed that Good Salary was the most ranked factor for both sub groups that made up the sample survey. However, a study from previous researches used in this study showed that different results could be obtained from different groups of already working employees. This study therefore can be seen as an introduction to a more detailed study to be carried by future researchers in the field of teachers’ motivation.

  5. Cyberbullying: a systematic review of research, its prevalence and assessment issues in Spanish studies

    Full Text Available Research on cyberbullying started at the beginning of the 21st century and the number of studies on the topic is increasing very rapidly. Nevertheless, the criteria used to define the phenomenon and evaluation strategies are still under debate. Therefore, it is still difficult to compare the findings among the studies or to describe their prevalence in different geographic areas or time points. Thus, the current systematic review has been conducted with the objective of describing the studies on the phenomenon in Spain taking into account its different definitions and evaluation strategies in relation to its prevalence. After conducting systematic searches and applying the inclusion criteria, 29 articles reporting the results of 21 different studies were included. It was found that the number of studies on the topic in Spain is growing and that most of the definitions include the criteria of repetition, intention, and power imbalance. It was also found that timeframes and cut-off points varied greatly among the studies. All the studies used self-reports with one-item or multi-item instruments. The prevalence also varied depending on the evaluation strategies and when assessed with multi-item instruments it was about twice as high as when assessed with one-item instruments. It is suggested that specific instruments should be chosen depending on the research questions posed in each investigation and that it could be useful to unify the criteria for further advancement of the field.

    The use of life-cycle assessment (LCA) to understand the embodied energy, environmental impacts, and potential energy-savings of manufactured products has become more widespread among researchers in recent years. This paper reviews recent LCA studies in the cement industry in China and in other countries and provides an assessment of the methodology used by the researchers compared to ISO LCA standards (ISO 14040:2006, ISO 14044:2006, and ISO/TR 14048:2002). We evaluate whether the authors provide information on the intended application, targeted audience, functional unit, system boundary, data sources, data quality assessment, data disaggregation and other elements, and draw conclusions regarding the level of adherence to ISO standards for the papers reviewed. We found that China researchers have gained much experience during last decade, but still have room for improvement in establishing boundaries, assessing data quality, identifying data sources, and explaining limitations. The paper concludes with a discussion of directions for future LCA research in China.

  7. Assessing Landscape Ecological Risk in a Mining City: A Case Study in Liaoyuan City, China

    2015-06-01

    Full Text Available Landscape ecological risk assessment can effectively identify key elements for landscape sustainability, which directly improves human wellbeing. However, previous research has tended to apply risk probability, measured by overlaying landscape metrics to evaluate risk, generally lacking a quantitative assessment of loss and uncertainty of risk. This study, taking Liaoyuan City as a case area, explores landscape ecological risk assessment associated with mining cities, based on probability of risk and potential ecological loss. The assessment results show landscape ecological risk is lower in highly urbanized areas than those rural areas, suggesting that not only cities but also natural and semi-natural areas contribute to overall landscape-scale ecological risk. Our comparison of potential ecological risk in 58 watersheds in the region shows that ecological loss are moderate or high in the 10 high-risk watersheds. The 35 moderate-risk watersheds contain a large proportion of farmland, and the 13 low-risk watersheds are mainly distributed in flat terrain areas. Our uncertainty analyses result in a close range between simulated and calculated values, suggesting that our model is generally applicable. Our analysis has good potential in the fields of resource development, landscape planning and ecological restoration, and provides a quantitative method for achieving landscape sustainability in a mining city.

  8. CHALLENGES IN ASSESSING CHARACTER EDUCATION IN ELT: IMPLICATIONS FROM A CASE STUDY IN A CHRISTIAN UNIVERSITY

    Full Text Available In this article I examine some challenges of assessing character education in the context of Teaching English as a Foreign Language in Indonesia (TEFLIN. Major sources of character education in Indonesia (e.g., Kurikulum 2013 seem to be religious values. However, there are two salient problems. First, in religiously inspired character education, there are concerns about religious values imposition. Second, it is oftentimes vague what types of, and how, character education can be evaluated in English language teaching and learning settings. In the context of an EFL teacher education program in a Christian university that I studied, one Christian student showed her religious dogmatism in classroom interactions or elsewhere in which peers having different religious views were present. Students’ communicative competence in expressing religious values can be assessed by examining their growing self-reflexivity (which problematizes dogmatism, among others, in their discourse. Character education assessment rubrics are developed from the cases reported here, in light of: (1 the Indonesian government’s guidelines for assessing character education; (2 critical ELT; and (3 Celce-Murcia’s (2007 model of communicative competence.

    Environmental impact assessment of agriculture has received increased attention over recent decades, leading to development of numerous methods. Among them, three deal with energy use: Energy Analysis (EA), Ecological Footprint (EF) and Emergy synthesis (Em). Based on a review of 197 references applying them to a variety of agricultural systems, this paper evaluates their ability to assess energy use. While EF assesses energy use as land use via a global accounting approach in which energy is only one component of the assessment, EA and Em are energy-focused and appear more appropriate to highlight ways to increase energy-use efficiency. EA presents a clear methodology via fossil energy use and its associated impacts but does not consider all energy sources. With inclusion of natural and renewable resources, Em focuses on other energy resources, such as solar radiation and energy from labour, but does not present impact indicators nor establish a clear link between activities and their environmental impacts. Improvements of the EA and Em methods could increase their ability to perform realistic and unbiased energy analysis or the diversity of livestock systems encountered in the world. First, to consider all energy sources, as Em does, EA could include solar radiation received by farm surfaces and energy expenditure by humans and animals to accomplish farm operations. Second, boundaries of the studied system in EA and Em must include draft animals, humans and communal grazing lands. Third, special attention should be given to update and locally adapt energy coefficients and transformities.

    SR suffered a right hemispheric stroke more than 3 years ago, and now lives with left-sided hemiparesis and chronic spatial neglect due to damaged white matter pathways connecting the frontal, temporal and parietal regions. We report here that SR suffers from both viewer-centered (i.e., egocentric) and object-centered (i.e., allocentric) spatial neglect. Notably, unlike most neuropsychological and functional assessments that focus on egocentric deficits, a specialized neuropsychological figurative discrimination test (the Apples test) revealed SR's allocentric neglect. Further, using assessments sensitive to detect functional deficits related to allocentric neglect, we observed SR's difficulty in reading and using clocks, reflecting his object-centered errors in these everyday activities. SR's case suggests that allocentric-specific assessments, both neuropsychological and functional, are valuable in standard neglect examinations, particularly to predict daily function after stroke. We recommend that neglect-related functional disability be distinguished further with respect to allocentric spatial deficits, and functional assessments for allocentric neglect should be validated in future large sample studies. Identifying allocentric neglect early, and learning about its influence on daily function, may enhance care quality and facilitate effective rehabilitation planning for stroke recovery.

    Full Text Available Creative projects in various fields are often subjected to afterthe- fact 'post-mortem' assessments to better understand their successes and failures. Names for these include project retrospectives or post occupancy evaluations (POEs depending on their field of origin. This case study from the architecture field will show the utility of engaging in multiple rounds of post-mortem activities in order to assess the solution from multiple stakeholder perspectives and in doing so, more fully recognize its strengths and weaknesses. The design of a homeless shelter bedroom was subjected to two POE analyses: a 'demand side' focused study that analyzed user accommodation, and a 'supply side' study that addressed issues including budget and funding. The two POEs yielded both corroborative and contrasting findings that sometimes worked at cross purposes. Three evaluation tactics emerged that could be extended to other fields' post mortem assessment activities: 1 conduct two or more POEs; 2 vary the POE criteria so that one is deep and focused 'demand side' user analysis and the other is 'supply side' operational and installation issues; and 3 conduct the POEs over a broad time period.

    Magnetic resonance imaging overcomes the limitations of videofluoroscopy in assessing without radiation exposure. The clinical utility of dynamic MRI for swallowing disorders is not well documented. This study demonstrates the feasibility of using dynamic MRI in assessment of swallowing disorders. Ten normal and three brainstem lesion patients participated in this study. GE Signa HDxt 1.5 Tesla MRI scanner with head-and-neck coil as a receiver and fast imaging employing steady state acquisition sequence was used. The swallow was analyzed in terms of symmetry and amplitude of movements of velum, faucial pillars, tongue, epiglottis and cricopharyngeous and images from the sagittal, coronal and axial planes. In sagittal plane posterior movement of tongue and its compression on velum, elevation of hyoid bone, elevation of larynx and lid action of epiglottis, in the coronal view the symmetrical movements of the faucial pillars and pharyngeal constrictor muscles and in axial plane three anatomical landmarks were targeted based on their role in swallowing, viz. velum, epiglottis and cricopharyngeous were studied. In brainstem lesion individuals, posterior movement of tongue, and elevation of larynx were not seen. Asymmetrical movements of faucial pillars and cricopharyngeous muscle were appreciated in the dynamic MRI. This demonstrates that, dynamic MRI is an efficient tool to understand the swallowing physiology and helps the speech language pathologist in modifying the swallowing maneuvers. Dynamic MRI is an effective tool in assessing swallowing and its disorders. This muscle specific information is not appreciated in videofluoroscopy and this information is necessary to modify the therapy maneuvers.

    2014-12-01

    Mobile phone-based data collection encompasses the richness of social network research. Both individual-level and network-level measures can be recorded. For example, health-related behaviors can be reported via mobile assessment. Social interactions can be assessed by phone-log data. Yet the potential of mobile phone data collection has largely been untapped. This is especially true of egocentric studies in public health settings where mobile phones can enhance both data collection and intervention delivery, e.g. mobile users can video chat with counselors. This is due in part to privacy issues and other barriers that are more difficult to address outside of academic settings where most mobile research to date has taken place. In this article, we aim to inform a broader discussion on mobile research. In particular, benefits and challenges to mobile phone-based data collection are highlighted through our mobile phone-based pilot study that was conducted on egocentric networks of 12 gay men (n = 44 total participants). HIV-transmission and general health behaviors were reported through a mobile phone-based daily assessment that was administered through study participants' own mobile phones. Phone log information was collected from gay men with Android phones. Benefits and challenges to mobile implementation are discussed, along with the application of multi-level models to the type of longitudinal egocentric data that we collected.

    About two-thirds of the vital genes in the Drosophila genome are involved in eye development, making the fly eye an excellent genetic system to study cellular function and development, neurodevelopment/degeneration, and complex diseases such as cancer and diabetes. We developed a novel computational method, implemented as Flynotyper software (http://flynotyper.sourceforge.net), to quantitatively assess the morphological defects in the Drosophila eye resulting from genetic alterations affecting basic cellular and developmental processes. Flynotyper utilizes a series of image processing operations to automatically detect the fly eye and the individual ommatidium, and calculates a phenotypic score as a measure of the disorderliness of ommatidial arrangement in the fly eye. As a proof of principle, we tested our method by analyzing the defects due to eye-specific knockdown of Drosophila orthologs of 12 neurodevelopmental genes to accurately document differential sensitivities of these genes to dosage alteration. We also evaluated eye images from six independent studies assessing the effect of overexpression of repeats, candidates from peptide library screens, and modifiers of neurotoxicity and developmental processes on eye morphology, and show strong concordance with the original assessment. We further demonstrate the utility of this method by analyzing 16 modifiers of sine oculis obtained from two genome-wide deficiency screens of Drosophila and accurately quantifying the effect of its enhancers and suppressors during eye development. Our method will complement existing assays for eye phenotypes, and increase the accuracy of studies that use fly eyes for functional evaluation of genes and genetic interactions. PMID:26994292

    Full Text Available Abstract Background Musculoskeletal physiotherapists routinely assess lumbar segmental motion during the clinical examination of a patient with low back pain. The validity of manual assessment of segmental motion has not, however, been adequately investigated. Methods In this prospective, multi-centre, pragmatic, diagnostic validity study, 138 consecutive patients with recurrent or chronic low back pain (R/CLBP were recruited. Physiotherapists with post-graduate training in manual therapy performed passive accessory intervertebral motion tests (PAIVMs and passive physiological intervertebral motion tests (PPIVMs. Consenting patients were referred for flexion-extension radiographs. Sagittal angular rotation and sagittal translation of each lumbar spinal motion segment was measured from these radiographs, and compared to a reference range derived from a study of 30 asymptomatic volunteers. Motion beyond two standard deviations from the reference mean was considered diagnostic of rotational lumbar segmental instability (LSI and translational LSI. Accuracy and validity of the clinical assessments were expressed using sensitivity, specificity, and likelihood ratio statistics with 95% confidence intervals (CI. Results Only translation LSI was found to be significantly associated with R/CLBP (p Conclusion This study provides the first evidence reporting the concurrent validity of manual tests for the detection of abnormal sagittal planar motion. PAIVMs and PPIVMs are highly specific, but not sensitive, for the detection of translation LSI. Likelihood ratios resulting from positive test results were only moderate. This research indicates that manual clinical examination procedures have moderate validity for detecting segmental motion abnormality.

    1992-11-01

    The Environmental Monitoring and Assessment Program (EMAP) was initiated by the U.S. Environmental Protection Agency (EPA) to monitor the condition of the Nation's natural resources. The Wetlands component of EMAP is designed to quantitatively assess the current status and long-term trends in wetland condition at regional and national scales. In the short-term, EMAP-Wetlands will provide standarized protocols for measuring and describing wetland condition, report on estimates of wetland condition in selected regions of the country, and develop standardized formats for reporting results. EMAP-Wetlands is being implemented by wetland class and geographic regions in three phases. Pilot studies are being conducted in small geographic regions (e.g., states) during the first phase to evaluate the ability of potential indicators to meet certain selection criteria. These studies will be followed by demonstration studies that evaluate the performance of indicators on larger scales (e.g., Gulf Coast region). Indicators that successfully meet critical criteria will be implemented regionally and nationally to assess wetland condition.

    Full Text Available Along with the proliferation of Open Access (OA publishing, the interest for comparing the scientific quality of studies published in OA journals versus subscription journals has also increased. With our study we aimed to compare the methodological quality and the quality of reporting of primary epidemiological studies and systematic reviews and meta-analyses published in OA and non-OA journals.In order to identify the studies to appraise, we listed all OA and non-OA journals which published in 2013 at least one primary epidemiologic study (case-control or cohort study design, and at least one systematic review or meta-analysis in the field of oncology. For the appraisal, we picked up the first studies published in 2013 with case-control or cohort study design from OA journals (Group A; n = 12, and in the same time period from non-OA journals (Group B; n = 26; the first systematic reviews and meta-analyses published in 2013 from OA journals (Group C; n = 15, and in the same time period from non-OA journals (Group D; n = 32. We evaluated the methodological quality of studies by assessing the compliance of case-control and cohort studies to Newcastle and Ottawa Scale (NOS scale, and the compliance of systematic reviews and meta-analyses to Assessment of Multiple Systematic Reviews (AMSTAR scale. The quality of reporting was assessed considering the adherence of case-control and cohort studies to STrengthening the Reporting of OBservational studies in Epidemiology (STROBE checklist, and the adherence of systematic reviews and meta-analyses to Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA checklist.Among case-control and cohort studies published in OA and non-OA journals, we did not observe significant differences in the median value of NOS score (Group A: 7 (IQR 7-8 versus Group B: 8 (7-9; p = 0.5 and in the adherence to STROBE checklist (Group A, 75% versus Group B, 80%; p = 0.1.

    2011-12-01

    Venous thromboembolism is a frequent clinical condition with high impact on both morbidity and mortality. Venous thromboembolism risk is particularly high in hospitalized patients as well as in oncologic patients, being a factor of poor prognosis for the oncologic disease. Several clinical studies have shown the need to develop effective hospital strategies using a systematic and individualized assessment of venous thromboembolism risk, and additionally to optimize the institution of prophylaxis treatment and its proper use in the context of in-hospital and outpatient management. The ARTE national study is a non-interventional, multicentre, prospective study which is divided in two phases. In the first phase patients are followed in the hospital; in the second phase patients are followed in ambulatory context for a period of 6 months after discharge. Four thousand patients will be included, equally distributed over medical, surgical, oncologic and orthopaedic patients. Data will be collected from the patient's clinical files and through direct clinical evaluation of risk factors for venous thromboembolism, in the departments of medicine, oncology, surgery, and orthopaedics of the participating centres. The main objectives of the study are to assess the risk profile of venous thromboembolism of the study population using a risk assessment model adapted from the Caprini and Khorana et al models, and the validation of the score for the Portuguese population. Simultaneously, the secondary objectives are as follows: to determine the proportion of patients with venous thromboembolism risk, according to the risk assessment model, that are doing prophylaxis; to determine the duration of prophylaxis during the hospitalization; to determine the proportion of patients doing long-term prophylaxis, at the moment of the discharge; to determine the incidence of thromboembolic events (deep venous thrombosis; stroke; pulmonary thromboembolism; transient ischemic attack

    Full Text Available Abstract Background Decisions on disability pensions are based, among others, on medical reports. The way these medical assessments are performed is largely unclear. The aim of the study was to determine which grounds are used by social insurance physicians (SIPs in these assessments and to determine if the identification of these grounds can help improve the quality of assessments in social insurance practice. The article describes a focus group study and a questionnaire study with SIPs in four different countries. Method Using focus group discussions of SIPs discussing the same case in Belgium, the Netherlands, Norway and Slovenia (N = 29 we determined the arguments and underlying grounds as used by the SIP's. We used a questionnaire study among other SIPs (N = 60 in the same countries to establish a first validation of these grounds. Results Grounds in the focus groups were comparable between the countries studied. The grounds were also recognized by SIPs who had not participated in the focus groups. SIPs agreed most on grounds with regard to the claimant's health condition, and about the claimant's duty to explore rehabilitation and work resumption, but less on accepting permanent incapacity when all options for treatment were exhausted. Conclusion Grounds that SIPs use refer to a limited group of key elements of disability evaluation. SIPs interpret disability in social insurance according to the handicapped role and strive at making their evaluation fair trials. ICF is relevant with regard to the health condition and to the process of evaluation. Identification of grounds is a valuable instrument for controlling the quality of disability evaluation. The grounds also appear to be internationally comparable which may enhance scientific study in this area.

    Full Text Available While most R&D activities in the multimedia field today focus on developing new algorithms and tools to automatically understand, index, manage and present media contents so that they could be used to help reduce people’s manual efforts in dealing with large amount of media contents, the issues of linking the developing or developed algorithms and tools to realistic end-user scenarios and applications have largely been relegated to other disciplines such as Human-Computer Interaction (HCI and Interaction Design. In this paper we present our reflection and interpretation of a multimedia project developing an end-to-end novel application incorporating a state-of-the-art “movie scene detection and classification” technique. Unlike any other technology-oriented projects in the multimedia community, this project attempted to bring usability engineering to the core of our experimental system development, extensively adopting the procedures, tools and methods available in usability engineering throughout all stages of the project – user study, ideation, interaction sketching, system implementation and deployment. Largest amount of effort was put to deployment stage, which involved facilitating the web-based system to 256 students in a film study course during a 3 month-long semester, during which the lecturers from the course provided necessary administration and coordination such as access to students, assignments and lab tutorials in order to fully integrate the system to the delivery of the course. Qualitative and quantitative data on the use of the system were recorded over time and analysed, to better understand the nature and characteristics of the developed system and its novel features afforded by the multimedia technology.

    A demonstration study was conducted in May 1994 on Bayou Chico to assess the utility of various assessment and measurement endpoints in determining the condition of bayous and estuaries. Bayou Chico has water quality problems attributed to its low flushing rate and urban/industrial land use in its watershed. The sampling scheme assessed the within-sampling station and spatial variability of measurement endpoints. Fourteen sampling stations in Bayou Chico and 3 stations in Pensacola Bay were selected based on an intensified EMAP sampling grid. Time and space coordinated sampling was conducted for: sediment contaminants and properties, sediment toxicity, water quality, benthic infauna, zooplankton and phytoplankton populations. Fish and crabs were also collected and analyzed for a suite of biomarkers and organic chemical residues. Primary productivity was measured via the light bottle dark bottle oxygen method and via diurnal oxygen measurements made with continuous recording data sondes. Stream sites were evaluated for water and sediment quality, water and sediment toxicity, benthic invertebrates and fish. Watershed analyses included assessment of land use/landcover (via SPOT and TM images), soils, pollution sources (point and non-point) and hydrography. These data were coordinated via an Arc/Info GIS system for display and spatial analysis. 1994 survey data were used to parameterize environmental fate models such as SWMM (Storm Water Management Model), DYNHYD5 (WASP5 hydrodynamics model) and WASP5 (Water Quality Analysis Simulation Program) to make predictions about the dynamics and fate of chemical contaminants in Bayou Chico. This paper will present an overview, and report on the results in regards to within-site and spatial variability in Bayou Chico. Conclusions on the efficacy of the assessment and measurement endpoints in evaluating the condition (health) of Bayou Chico will be presented.

    Full Text Available Nowadays, there are several models to evaluate technological acceptance of software developed through Action Design Research and Action Research. These models rely on quantitative techniques to study user behavioural intentions and thus predict the use of a technology. This paper presents our experiences in using qualitative methods to assess such acceptance in the development of specialized tools for Strategic Scanning. Our study suggests that qualitative methods can be an alternative to evaluate technology acceptance in situations where the number of users is small or where there are requirements for continuous improvement.

    Full Text Available The problem of this article is to answer the question whether and to what extent the learning outcomes are achieved by students? The problem is illustrated on the basis of own research carried out on one of education university, majoring in Economics. The effectiveness of the implementation of the effects will be studied based on the subjective opinions of students regarding the scope of their assimilation. Survey was realized within pilot program as a part of systematic survey program “ An assessment of Economy study direction by the students” pointed in introducing students opinions concerning both quality and effectiveness of education but practical-implementation aim is to elaborate indications to improve education quality. An author used public opinion research – questionnaires to collect information. Subjective assessment of education effects realization level by students is positive but it is difficult to determine at that survey stage how realistic above mentioned assessment is. In the opinion of students an effectiveness of practical skills and competences gaining depends upon used research methods like: activating and project methods.

    Full Text Available This paper assessed encroachment of streams due to physical development in Wa Urban Area of the Upper West Region of Ghana. The assessment was informed by the recognition that the roles played by streams in flood control are undermined by physical developments. This affects sustainable urban development and renders the urban area vulnerable to floods. The assessment was based on the 300m buffer zone standard set by the Ghana Water Resources Commission as a protective zone for such streams in the country. It is mandatory to offset all physical development from this zone but that is not the situation on the ground. For the purpose of this study each buffer zone was divided into sub-buffer zones of 100m in order to appreciate how far development has moved into the prohibited buffer zone. The streams and physical structures were mapped with a Trimble GPS receiver while land owners and tenants were purposively selected and interviewed. The buffer zone and sub-buffer zones were defined using GIS and overlaid with map of the physical structures. The categories of structures found in the buffer zones were residential (93.4 %, commercial (5.1%, public (1.3% and agriculture (0.2%. The results of the study indicates that more than 50 % of physical structures mapped are located in the inner buffer and the land acquisition process for development of these structures amongst others in Wa is mostly initiated by developers.

  10. Do Metacognitions and Intolerance of Uncertainty Predict Worry in Everyday Life? An Ecological Momentary Assessment Study.

    Cognitive models of generalized anxiety disorder (GAD) suggest that excessive worry is due to positive and negative metacognitive beliefs and/or intolerance of uncertainty. Empirical support mainly derives from cross-sectional studies with limited conclusiveness, using self-report measures and thereby possibly causing recall biases. The aim of the present study therefore was to examine the power of these cognitive variables to predict levels of worry in everyday life using Ecological Momentary Assessment (EMA). Metacognitions and intolerance of uncertainty were assessed using well-established self-report questionnaires in 41 nonclinical participants who subsequently completed ratings on worry intensity and burden on a portable device for 1week at seven times a day once every 2hours. Results showed significant associations of negative metacognitive beliefs and intolerance of uncertainty, but not positive metacognitive beliefs, with worry in everyday life. In multilevel regression analyses, a substantial proportion of variance of everyday worry could be accounted for by negative metacognitions over and above trait worry and daily hassles. Intolerance of uncertainty likewise emerged as a valid predictor when tested in isolation, but did not explain additional variance once negative metacognitions were controlled. The findings support current cognitive models of excessive worry and highlight the role of negative metacognitions. By using EMA to assess levels of worry in everyday life, they extend earlier findings focusing exclusively on retrospective questionnaire measures.

    Questionnaire and interview assessment can provide reliable data on attitudes and self-perceptions on emotion, and experimental laboratory assessment can examine functional relations between stimuli and reactions under controlled conditions. On the other hand, ambulatory assessment is less constrained and provides naturalistic data on emotion in daily life, with the potential to (1) assure external validity of laboratory findings, (2) provide normative data on prevalence, quality and intensity of real-life emotion and associated processes, (3) characterize previously unidentified emotional phenomena, and (4) model real-life stimuli for representative laboratory research design. Technological innovations now allow for detailed ambulatory study of emotion across domains of subjective experience, overt behavior and physiology. However, methodological challenges abound that may compromise attempts to characterize biobehavioral aspects of emotion in the real world. For example, emotional effects can be masked by social engagement, mental and physical workloads, as well as by food intake and circadian and quasi-random variation in metabolic activity. The complexity of data streams and multitude of factors that influence them require a high degree of context specification for meaningful data interpretation. We consider possible solutions to typical and often overlooked issues related to ambulatory emotion research, including aspects of study design decisions, recording devices and channels, electronic diary implementation, and data analysis.

    Recent clinical practice parameters encourage systematic use of concussion surveillance/management tools that evaluate participating athletes at baseline and after concussion. Office-based tools (Sports Concussion Assessment Tool; SCAT2) require accurate baseline assessment to maximize utility but no normative data exist for children on the SCAT2, limiting identification of "normal" or "impaired" score ranges. The purpose of this study was to develop child and adolescent baseline norms for the SCAT2 to provide reference values for different age groups. A community-based approach was implemented to compile baseline performance data on the SCAT2 in 761 children aged 9 to 18 to create age- and sex-graded norms. Findings indicate a significant age effect on SCAT2 performance such that older adolescents and teenagers produced higher (better) total scores than younger children (ages 9 to 11) driven by age differences on individual components measuring cognition (SAC), postural stability (BESS), and symptom report. Females endorsed greater numbers of symptoms at baseline than males. Normative data tables are presented. Findings support the SCAT2 as a useful clinical tool for assessing baseline functioning in teenagers, but suggest clinical utility may be limited in children under age 11. Follow-up studies after incident concussion are needed to confirm this assumption.

    Multifaceted community interventions directed at improving food environments are emerging, but their impact on dietary change and obesity prevalence has not been adequately documented. The Healthy Communities Study (HCS) is seeking to identify characteristics and combinations of programs and policies that are associated with children's diets and obesity-related outcomes in various types of communities across the U.S. The purpose of this paper is to describe the methods used in 2013-2015 in the HCS to assess dietary intake, school nutrition environments, and other nutrition-related behaviors. The conceptual framework of the HCS is based on the socioecological model and behaviors shown in previous studies to be related to obesity in children guided selection of domains. Nine domains were identified as essential measures of nutrition in the HCS: (1) intake of selected foods and beverages; (2) food patterns and behaviors; (3) social support; (4) home environment; (5) school environment; (6) community environment; (7) breastfeeding history; (8) household food insecurity; and (9) dieting behaviors and body image. Children's dietary intake was assessed using a dietary screener and up to two automated 24-hour recalls. Dietary-related behaviors were assessed by a survey administered to the parent, child, or both, depending on child age. School nutrition measures were obtained from a combination of school staff surveys and researcher observations. Information from these measures is expected to contribute to a better understanding of "what is working" to improve the dietary behaviors that are likely to prevent obesity and improve health in children.

    The purpose of this study is to quantitatively assess the myocardial perfusion by first-pass technique in swine model. Numerous techniques based on the analysis of Computed Tomography (CT) Hounsfield Unit (HU) density have emerged. Although these methods proposed to be able to assess haemodynamically significant coronary artery stenosis, their limitations are noticed. There are still needs to develop some new techniques. Experiments were performed upon five (5) closed-chest swine. Balloon catheters were placed into the coronary artery to simulate different degrees of luminal stenosis. Myocardial Blood Flow (MBF) was measured using color microsphere technique. Fractional Flow Reserve (FFR) was measured using pressure wire. CT examinations were performed twice during First-pass phase under adenosine-stress condition. CT HU Density (HUDCT) and CT HU Density Ratio (HUDRCT) were calculated using the acquired CT images. Our study presents that HUDRCT shows a good (y=0.07245+0.09963x, r2=0.898) correlation with MBF and FFR. In receiver operating characteristic (ROC) curve analyses, HUDRCT provides excellent diagnostic performance for the detection of significant ischemia during adenosine-stress as defined by FFR indicated by the value of Area Under the Curve (AUC) of 0.927. HUDRCT has the potential to be developed as a useful indicator of quantitative assessment of myocardial perfusion.

    In the continuation of PYROREP (FP5), the pyrochemical domain of EUROPART (FP6) involves today 7 European participants and 2 international partners in order to assess treatment processes which could be used in a broad variety of fuel cycles: molten salt reactor spent fuel, metallic, oxide, carbide or nitride fuels from any reactors. Indeed, a pyrochemical process is not sensitive to radiolysis, and obviously to temperature effects, and could afford to treat fuels after a short cooling period, even at high concentrations. Within EUROPART, the chemistry of actinides and of some fission products was studied in depth in either chloride or fluoride molten salts. Laboratory-scale demonstration experiments were used in order to assess electrolytic processes in molten chlorides and liquid-liquid reductive extraction in molten fluoride/liquid aluminum. An electrolysis process is also under development in molten fluoride. To complete the studies, the development of devices and the modeling of processes are taken into consideration. In order to be fitted for acceptance, a process has to produce minimal quantities of wastes, compatible with storage constraints. Therefore, decontamination techniques, as well as materials suitable for disposal, have to be developed. Fission products precipitation by carbonate and phosphate, and filtration on zeolites were studied. Some original confinement matrices such as sodalite or pollucite were also studied. Integration studies have been carried out in order to evaluate and to compare some selected process flowsheets and possibly to redirect development programs. (authors)

    2012-09-01

    Full Text Available Abstract Background Currently over 50% of drugs prescribed to children have not been evaluated properly for use in their age group. One key reason why children have been excluded from clinical trials is that they are not considered able to exercise meaningful autonomy over the decision to participate. Dutch law states that competence to consent can be presumed present at the age of 12 and above; however, in pediatric practice children’s competence is not that clearly presented and the transition from assent to active consent is gradual. A gold standard for competence assessment in children does not exist. In this article we describe a study protocol on the development of a standardized tool for assessing competence to consent in research in children and adolescents. Methods/design In this study we modified the MacCAT-CR, the best evaluated competence assessment tool for adults, for use in children and adolescents. We will administer the tool prospectively to a cohort of pediatric patients from 6 to18 years during the selection stages of ongoing clinical trials. The outcomes of the MacCAT-CR interviews will be compared to a reference standard, established by the judgments of clinical investigators, and an expert panel consisting of child psychiatrists, child psychologists and medical ethicists. The reliability, criterion-related validity and reproducibility of the tool will be determined. As MacCAT-CR is a multi-item scale consisting of 13 items, power was justified at 130–190 subjects, providing a minimum of 10–15 observations per item. MacCAT-CR outcomes will be correlated with age, life experience, IQ, ethnicity, socio-economic status and competence judgment of the parent(s. It is anticipated that 160 participants will be recruited over 2 years to complete enrollment. Discussion A validity study on an assessment tool of competence to consent is strongly needed in research practice, particularly in the child and adolescent population. In

    . The assessment, both on open loop and closed loop, was carried out based on an industrial case study and compared to a modified case without heat integration. Although the heat integrated system displayed a certain deterioration of controllability, the control system made possible an efficient operation....... The reduction of energy consumption achieved thanks to heat integration was considerably larger than the losses due to poor control of the process, confirming the importance of heat integration in energy intensive processes.......Heat integration is essential for reducing the energy consumption of process industries. However, it may render the dynamic operation more interactive and difficult to control. This paper assesses the implications of heat integration in controllability and performance in energy reduction...

    Limiting Conditions for Operations (LCOs) are evaluated dynamically using the tool of system dynamics. The LCOs define the Allowed Outage Times (AOTs) and the actions to be taken if the repair cannot be completed within the AOT. System dynamics has been developed to analyze the dynamic reliability of a complicated system. System dynamics using Vensim software have been applied to LCOs assessment for an example system, the auxiliary feed water system of a reference nuclear power plant. Analysis results of both full power operation and shutdown operation have been compared for a measure of core damage frequency. The framework developed in this study has been shown to be very flexible in that it can be applied to assess LCOs quantitatively under any operational context of the TS in FSAR.
