    To evaluate the impact to the Columbia River from the Hanford Site-derived contaminants, the U.S. Department of Energy, U.S. Environmental Protection Agency, and Washington State Department of Ecology initiated a study referred to as the Columbia River Comprehensive Impact Assessment (CRCIA). To address concerns about the scope and direction of CRCIA as well as enhance regulator, tribal, stockholder, and public involvement, the CRCIA Management Team was formed in August 1995. The Team agreed to conduct CRCIA using a phased approach. The initial phase, includes two components: 1) a screening assessment to evaluate the potential impact to the river, resulting from current levels of Hanford-derived contaminants in order to support decisions on Interim Remedial Measures, and 2) a definition of the essential work remaining to provide an acceptable comprehensive river impact assessment. The screening assessment is described in Part I of this report. The essential work remaining is Part II of this report. The objective of the screening assessment is to identify areas where the greatest potential exists for adverse effects on humans or the environment. Part I of this report discusses the scope, technical approach, and results of the screening assessment. Part II defines a new paradigm for predecisional participation by those affected by Hanford cleanup decisions.

    The U.S. Department of Energy's (USDOE) Albuquerque Operations Office installations are being evaluated under its Comprehensive Environmental Assessment and Response Program (CEARP). The installations consist of eight weapons development and production facilities, which are located across the United States. The evaluation covers the major environmental regulations, with emphasis on the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and on the Resource Conservation and Recovery Act (RCRA). The CEARP is intended to help fulfill USDOE obligations for federal facilities under the U.S. Environmental Protection Agency (USEPA) CERCLA Program and constitutes the same basic approach as contained in USEPA guidance to federal facilities. The Program is a phased program to identify, assess, and correct existing and potential environmental concerns relative to these regulations. The five phases are Phase I - Installation Assessment, Phase II - Confirmation, Phase III - Technological Assessment, Phase IV - Remedial Action, and Phase V - Compliance and Verification. Phase I activities and reports should be completed during 1986. The Phase II generic sampling plans, data management plans, health and safety plans, and quality assurance/quality control plans will be prepared during 1986. Significant characterization of CERCLA sites will be initiated during 1987

    Because of past nuclear production operations along the Columbia River, there is intense public and tribal interest in assessing any residual Hanford Site related contamination along the river from the Hanford Reach to the Pacific Ocean. The Columbia River Comprehensive Impact Assessment was proposed to address these concerns. The assessment of the Columbia River is being conducted in phases. The initial phase is a screening assessment of the risk, which addresses current environmental conditions for a range of potential uses. One component of the screening assessment estimates the risk from contaminants in the Columbia River to the environment. The objective of the ecological risk assessment is to determine whether contaminants from the Columbia River pose a significant threat to selected receptor species that exist in the river and riparian communities of the study area. This report (1) identifies the receptor species selected for the screening assessment of ecological risk and (2) describes the selection process. The species selection process consisted of two tiers. In Tier 1, a master species list was developed that included many plant and animal species known to occur in the aquatic and riparian systems of the Columbia River between Priest Rapids Dam and the Columbia River estuary. This master list was reduced to 368 species that occur in the study area (Priest Rapids Dam to McNary Dam). In Tier 2, the 181 Tier 1 species were qualitatively ranked based on a scoring of their potential exposure and sensitivity to contaminants using a conceptual exposure model for the study area

    With growing calls for changes in the field of risk assessment, improved systematic approaches for addressing environmental issues with greater transparency and stakeholder engagement are needed to ensure sustainable trade-offs. Here we describe the comprehensive environmental assessment (CEA) approach as a holistic way to manage complex information and to structure input from diverse stakeholder perspectives to support environmental decision-making for the near- and long-term. We further note how CEA builds upon and incorporates other available tools and approaches, describe its current application at the U.S. Environmental Protection Agency, and point out how it could be extended in evaluating a major issue such as the sustainability of biofuels.

    The sentence comprehension test from the sentence comprehension cognitive examination (ECCO) battery can be used to assess children and adults with grammar comprehension disorders by means of a simple verification procedure that requires few memory resources. AIM. To present a psychometric analysis of the sentence comprehension test based on the classical theory of tests and on item response theory, as well as several studies that show its usefulness for assessing grammar comprehension in different populations. The test was applied to 2238 subjects with ages ranging from 6 to 85 years. The analysis shows that the test has a high overall reliability and, through the age groups that were considered, it includes elements that are especially discriminating or informative (lexical and syntactic distractors) and is biased towards medium-low levels of the trait. In view of the results, the sentence comprehension test from the ECCO battery provides a reliable measure of grammar comprehension through a wide variety of constructions and has great potential value for use in the clinical and research domains.

    Root Kustritz, Margaret V; Lowum, Susan; Flynn, Kristi; Fairbairn, Heather; Diesch-Chham, Athena

    The primary purpose of this study was to compare two methods for assessing student communication skills: a labor-intensive review of video-recorded interactions and global communications assessment using a comprehensive rotation-assessment tool. Secondary goals of the study were to evaluate student strengths and weaknesses to inform the pre-clinical communications curriculum and to evaluate for consistency between types of reviewers. Video recordings of 43 student encounters with clients presenting their animals for wellness or diagnostic appointments to the primary care service at a veterinary teaching hospital were reviewed by one of three primary care clinicians, a social worker, and a clinical communications instructor, using a common rubric. Scores using the rubric were compared with overall scores for verbal communications on a comprehensive rotation-assessment tool, both for the primary care rotation and for other small-animal rotations. Duration did not vary significantly between wellness and diagnostic appointments, or between dog and cat appointments. Scores achieved by students on video review varied by evaluator, with the clinical communications instructor scoring students the lowest and the social worker scoring students the highest. Strengths identified included greeting the client appropriately, gathering initial information about the reason for the visit, and using lay terminology appropriately. Weaknesses included summarizing information for the client, talking to clients about money, and making strong recommendations.

  14. Probabilistic Capacity Assessment of Lattice Transmission Towers under Strong Wind

    Full Text Available Serving as one key component of the most important lifeline infrastructure system, transmission towers are vulnerable to multiple nature hazards including strong wind and could pose severe threats to the power system security with possible blackouts under extreme weather conditions, such as hurricanes, derechoes, or winter storms. For the security and resiliency of the power system, it is important to ensure the structural safety with enough capacity for all possible failure modes, such as structural stability. The study is to develop a probabilistic capacity assessment approach for transmission towers under strong wind loads. Due to the complicated structural details of lattice transmission towers, wind tunnel experiments are carried out to understand the complex interactions of wind and the lattice sections of transmission tower and drag coefficients and the dynamic amplification factor for different panels of the transmission tower are obtained. The wind profile is generated and the wind time histories are simulated as a summation of time-varying mean and fluctuating components. The capacity curve for the transmission towers is obtained from the incremental dynamic analysis (IDA method. To consider the stochastic nature of wind field, probabilistic capacity curves are generated by implementing IDA analysis for different wind yaw angles and different randomly generated wind speed time histories. After building the limit state functions based on the maximum allowable drift to height ratio, the probabilities of failure are obtained based on the meteorological data at a given site. As the transmission tower serves as the key nodes for the power network, the probabilistic capacity curves can be incorporated into the performance based design of the power transmission network.

    Full Text Available The world today is constantly changing requiring organizations to adapt quickly and seek expertise to help meet the demands on their business. There are many workforce challenges that organizations seek to overcome, and one of the hardest things to do in modern corporations is to keep the talent pool young and vibrant. Early career hires tend to bring new and exciting ideas into play that may not even be considered by their more seasoned peers. The challenge with early career hires, especially in the Science, Technology, Engineeringand Math (STEM career fields, is the extreme difficulty in finding candidates who, not only have book knowledge, but also have hands-on, real world experience. Statistics show that this is a real concern to professional workforce employers. In this presentation, we highlight a model aimed at adopting new approaches for seeking and evaluating high quality candidates for on-boarding, conducting interviews and hiring to build a corporate talent pipeline. We discuss the model as it relates to recruiting, training, competition-based interviewing and providing hands-on work experience toward helping to build strong professionals in an organization. We conclude by highlighting several examples of successful approaches and their outcomes.

    A comprehensive geomechanical approach to wellbore stability requires knowledge of rock strength, pore pressure and the magnitude and orientation of the three principal stresses. These parameters are often uncertain, making confidence in deterministic predictions of the risks associated with instabilities during drilling and production difficult to assess. This paper demonstrates the use of Quantitative Risk Assessment (QRA) to formally account for the uncertainty in each input parameter to assess the probability of achieving a desired degree of wellbore stability at a given mud weight. We also utilize QRA to assess how the uncertainty in each parameter affects the mud weight calculated to maintain stability. In one case study, we illustrate how this approach allows us to compute optimal mud weight windows and casing set points at a deep-water site. In another case study, we demonstrate how to assess the feasibility of underbalanced drilling and open-hole completion of horizontal wells utilizing a comprehensive stability analysis that includes application of QRA.

  17. An Interactive View of Reading Comprehension: Implications for Assessment.

    2017-04-20

    This clinical focus article explores further the multidimensional view of reading comprehension put forward by Catts and Kamhi (2017) in this clinical forum and its implications for reading assessment. It is argued that a multidimensional or interactive view of reading predicts variability in student performance on reading assessments as a function of the interaction among reader, text, and task factors. Student performance on any given reading assessment should be interpreted in relation to the specific reading demands of the assessment, rather than as a fixed ability that generalizes to any given reading situation. This view implies a different approach to the use of both summative and classroom assessment than is currently common practice.

    Comprehension emerges as the results of inference and strategic processes that support the construction of a coherent mental model for a text. However, the vast majority of comprehension skills tests adopt a format that does not afford an assessment of these processes as they operate during reading. This study assessed the viability of the Reading Strategy Assessment Tool (RSAT), which is an automated computer-based reading assessment designed to measure readers' comprehension and spontaneous use of reading strategies while reading texts. In the tool, readers comprehend passages one sentence at a time, and are asked either an indirect ("What are your thoughts regarding your understanding of the sentence in the context of the passage?") or direct (e.g., why X?) question after reading each pre-selected target sentence. The answers to the indirect questions are analyzed on the extent that they contain words associated with comprehension processes. The answers to direct questions are coded for the number of content words in common with an ideal answer, which is intended to be an assessment of emerging comprehension. In the study, the RSAT approach was shown to predict measures of comprehension comparable to standardized tests. The RSAT variables were also shown to correlate with human ratings. The results of this study constitute a "proof of concept" and demonstrate that it is possible to develop a comprehension skills assessment tool that assesses both comprehension and comprehension strategies.

    2014-05-01

    Pneumatic actuators and electric actuators have almost been applied to all manufacturing industries. The two kinds of actuators can replace each other in most fields, such as the point to point transmission occasion and some rotating occasions. However, there are very few research results about the advantages and disadvantages of two kinds of actuators under the same working conditions so far. In this paper, a novel comprehensive assessment method, named as overall life cycle comprehensive assessment (OLCCA), is proposed for comparison and assessment of pneumatic and electric actuators. OLCCA contains mechanical properties evaluation (MPE), life cycle cost analysis based on users (LCCABOU) and life cycle environmental impact analysis (LCEIA) algorithm in order to solve three difficult problems: mechanical properties assessment, cost analysis and environmental impact assessment about actuators. The mechanical properties evaluation of actuators is a multi-objective optimization problem. The fuzzy data quantification and information entropy methods are combined to establish MPE algorithm of actuators. Two kinds of pneumatic actuators and electric actuators with similar bearing capacity and similar work stroke were taken for example to verify the correctness of MPE algorithm. The case study of MPE algorithm for actuators verified its correctness. LCCABOU for actuators is also set up. Considering cost complex structure of pneumatic actuators, public device cost even method (PDCEM) is firstly presented to solve cost division of public devices such as compressors, aftercooler, receivers, etc. LCCABOU method is also effective and verified by the three groups of pneumatic actuators and electric actuators. Finally, LCEIA model of actuators is established for the environmental impact assessment of actuators. LCEIA data collection method and model establishment procedure for actuators are also put forward. With Simapro 7, LCEIA comparison results of six actuators can be

    2016-10-06

    With an increasing number of older people using emergency services, researchers have raised concerns about the quality of care in an environment that is not designed to address older patients' specific needs and conditions. The comprehensive geriatric assessment (CGA) model was developed to address these issues, and to optimise healthcare delivery to older adults. This article introduces a complementary mnemonic, FRAIL, that refers to important elements of health information to consider before initiating care for older patients - falls/functional decline, reactions, altered mental status, illnesses, and living situation. It is not intended to replace the CGA, but can help to quickly identify high-risk older patients who warrant a more in-depth clinical assessment with CGA.

    2013-01-01

    The anticipated benefits of engineered nanomaterials (ENMs) should be weighed against their possible negative impacts. Comprehensive environmental assessment (CEA) provides a means of evaluating such trade-offs in a holistic and systematic manner. CEA consists of both a framework for organizing information and a process for using collective judgment to identify and prioritize the issues presented by ENMs. As a meta-assessment approach, CEA is designed to assist both research planners and risk managers by building on various assessment and analytic tools used by risk assessors. Given the immature state of the science for ENMs, CEA is currently being primarily used for prioritizing research directions. Therefore, highlights of case studies of selected ENM applications are presented to illustrate how CEA has been applied thus far to help guide research efforts to support future assessment efforts. In addition, CEA is discussed in relation to topical subjects, such as sustainability, transparency, and stakeholder engagement. Finally, comparisons to other life cycle-based assessment approaches directed at ENMs are noted. Copyright © 2012 Wiley Periodicals, Inc.

    2011-07-01

    Advanced therapy medicinal products (ATMP) are associated with high expectations because they offer new opportunities for the treatment of diseases, e.g., the possibility of regenerating damaged or lost tissue. What the products (gene therapy, somatic cell therapy, and tissue engineered products) have in common is an innovative and complex development process that combines science and engineering. At the same time, this field of research is becoming increasingly interdisciplinary and requires international cooperation. A comprehensive assessment of ATMP has to take these issues into account. The application of Beauchamp and Childress' Four Principles (Principle-Based Ethics) as well as Discourse Ethics as a framework may lead to a broader consideration of medical ethics issues.

    2015-01-15

    Intrinsically disordered regions are key for the function of numerous proteins. Due to the difficulties in experimental disorder characterization, many computational predictors have been developed with various disorder flavors. Their performance is generally measured on small sets mainly from experimentally solved structures, e.g. Protein Data Bank (PDB) chains. MobiDB has only recently started to collect disorder annotations from multiple experimental structures. MobiDB annotates disorder for UniProt sequences, allowing us to conduct the first large-scale assessment of fast disorder predictors on 25 833 different sequences with X-ray crystallographic structures. In addition to a comprehensive ranking of predictors, this analysis produced the following interesting observations. (i) The predictors cluster according to their disorder definition, with a consensus giving more confidence. (ii) Previous assessments appear over-reliant on data annotated at the PDB chain level and performance is lower on entire UniProt sequences. (iii) Long disordered regions are harder to predict. (iv) Depending on the structural and functional types of the proteins, differences in prediction performance of up to 10% are observed. The datasets are available from Web site at URL: http://mobidb.bio.unipd.it/lsd. Supplementary data are available at Bioinformatics online. © The Author 2014. Published by Oxford University Press.

    The Columbia River Comprehensive Impact Assessment (CRCIA) Project at the Pacific Northwest Laboratory (PNL) is evaluating the current human and ecological risks from contaminants in the Columbia River. The risks to be studied are those attributable to past and present activities on the Hanford Site. The Hanford Site is located in southcentral Washington State near the town of Richland. Human risk from exposure to radioactive and hazardous materials will be addressed for a range of river use options. Ecological risk will be evaluated relative to the health of the current river ecosystem. The overall purpose of the project is to determine if enough contamination exists in the Columbia River to warrant cleanup actions under applicable environmental regulations. This report documents an initial review, from a risk perspective, of the wealth of historical data concerning current or potential contamination in the Columbia River. Sampling data were examined for over 600 contaminants. A screening analysis was performed to identify those substances present in such quantities that they may pose a significant human or ecological risk. These substances will require a more detailed analysis to assess their impact on humans or the river ecosystem.

We used Dr. SUPERMAN to examine patients with AD (24 men and 53 women, mean age 83.0 ± 5.1 years), VaD (10 men and 12 women, mean age 80.4 ± 5.0 years) and DLB (28 men and 20 women, mean age 81.2 ± 5.5 years). Patients with DLB or VaD had functional deficits more frequently than those with AD in many fields. Significant correlations between functional impairments and clinical characteristics, such as age, sex and Mini-Mental State Examination scores, in the non-AD group (including DLB and VaD) were found in more extensive fields than those in the AD group. Patients with dementia, particularly DLB, have several geriatric problems. Correlations between functional deficits and clinical characteristics differ between the AD group and the non-AD group. Non-AD patients of older age who are male and have advanced dementia are more likely have several functional deficits. In addition to age and severity of dementia, the type of dementia should be considered in the treatments and interventions of elderly patients with dementia. © 2014 Japan Geriatrics Society.

    Recently, the US NRC Regulatory Guide 1.20(RG 1.20) was revised to allow the usage of CFD code in the analysis program of a comprehensive vibration assessment program (CVAP) for reactor vessel internals (RVIs). Thus, the analysis program of Shin-Kori no.4 RVI CVAP has been developed according to the revised guideline of RG1.20 Rev. 3. The analysis program consists of a hydraulic analysis to calculate the hydraulic forcing functions and a structural response analysis with inputting the calculated hydraulic forcing functions on each component of RVIs. The hydraulic forcing functions are comprised of the deterministic loads induced by the rotor and blade of reactor coolant pump (RCP) and the random loads generated by the flow turbulence. In this study, according to the RG1.20 Rev. 3, the hydraulic analysis methodology of RVI CVAP was developed to use the CFD codes. In order to verify the developed hydraulic methodology, the deterministic and random loads of Yonggwang no.4 RVIs were calculated with modeling the fluid domain model of reactor vessel in the full 3D and verified through the comparison between the calculated results and the measured data in the Yonggwang no.4 RVI CVAP test

    The development of transgenic cloned animals offers new opportunities for agriculture, biomedicine and environmental science. Expressing recombinant proteins in dairy animals to alter their milk composition is considered beneficial for human health. However, relatively little is known about the expression profile of the proteins in milk derived from transgenic cloned animals. In this study, we compared the proteome and nutrient composition of the colostrum and mature milk from three lines of transgenic cloned (TC) cattle that specifically express human α-lactalbumin (TC-LA), lactoferrin (TC-LF) or lysozyme (TC-LZ) in the mammary gland with those from cloned non-transgenic (C) and conventionally bred normal animals (N). Protein expression profile identification was performed, 37 proteins were specifically expressed in the TC animals and 70 protein spots that were classified as 22 proteins with significantly altered expression levels in the TC and C groups compared to N group. Assessment of the relationship of the transgene effect and normal variability in the milk protein profiles in each group indicated that the variation in the endogenous protein profiles of the three TC groups was within the limit of natural variability. More than 50 parameters for the colostrum and mature milk were compared between each TC group and the N controls. The data revealed essentially similar profiles for all groups. This comprehensive study demonstrated that in TC cattle the mean values for the measured milk parameters were all within the normal range, suggesting that the expression of a transgene does not affect the composition of milk.

    Within a hybrid strong/weak coupling model for jets in strongly coupled plasma, we explore jet modifications in ultra-relativistic heavy ion collisions. Our approach merges the perturbative dynamics of hard jet evolution with the strongly coupled dynamics which dominates the soft exchanges between the fast partons in the jet shower and the strongly coupled plasma itself. We implement this approach in a Monte Carlo, which supplements the DGLAP shower with the energy loss dynamics as dictated by holographic computations, up to a single free parameter that we fit to data. We then augment the model by incorporating the transverse momentum picked up by each parton in the shower as it propagates through the medium, at the expense of adding a second free parameter. We use this model to discuss the influence of the transverse broadening of the partons in a jet on intra-jet observables. In addition, we explore the sensitivity of such observables to the back-reaction of the plasma to the passage of the jet.

    Comprehensive geriatric assessment (CGA) is a process that consists of a multidimensional data-search and a process of analyzing and linking patient characteristics creating an individualized intervention-plan, carried out by a multidisciplinary team. In general, the positive health care effects of CGA are established, but in oncology both CGA and the presence of geriatric syndromes still have to be implemented to tailor oncological therapies to the needs of elderly cancer patients. In this paper the conceptualization of geriatric syndromes, their relationship to CGA and results of clinical studies using CGA in oncology are summarized. Geriatric syndromes are associated with increased vulnerability and refer to highly prevalent, mostly single symptom states (falls, incontinence, cognitive impairment, dizziness, immobility or syncope). Multifactorial analysis is common in geriatric syndromes and forms part of the theoretical foundation for using CGA. In oncology patients, we reviewed the value of CGA on the following endpoints: recognition of health problems, tolerance to chemotherapy and survival. Most studies performed CGA to identify prognostic factors and did not include an intervention. The ability of CGA to detect relevant health problems in an elderly population is reported consistently but no randomized studies are available. CGA should explore the pre-treatment presence of (in)dependence in Instrumental Activities of Daily Living (IADL), poor or moderately poor quality of life, depressive symptoms and cognitive decline, and thereby may help to predict survival. However, if scored by the Charlson comorbidity-index, comorbidities are not convincingly related to survival. The few studies that included a CGA-linked intervention show inconsistent results with regard to survival but compared to usual care quality of life is improved in the surviving period. Functional performance scores and dependency at home appeared to be independent predictive factors for

    Full Text Available In this study we present our adaptation and preliminary standardization of Test for Reception of Grammar TROG (Bishop, 1989 for Serbian language. TROG is a receptive test of grammatical structures, constructed primarily for an assessment of grammatical development and detection of children with Specific Language Impairment (SLI. Due to the lack of standardized tests for language development in our clinical community, TROG is selected for adaptation as a test which includes two components relevant for discrimination of children with language difficulties: a measure of receptive abilities and b distinguishing knowledge of grammar from semantic aspect of comprehension. Preliminary standardization was done on a sample of 335 participants between 4 and 7 years of age, divided into 8 age subsamples. Since dynamic of language change at early ages is faster, age samples covered range of 3 months at the ages 4;0-4;2, 4;3-4;5, 4;6-4;8, 4;9-4;11, and range of 6 months at the ages 5;0-5;5, 5;6-5;11, 6;00-6;05, 6;06-6;11. Analyses have revealed that the first version of Serbian TROG is discriminative for the differences between age samples, but discrimination is smaller then it was expected. The test discriminates three age-samples (4;0-4;8, 4;9-5;5, and 5;6-6;11. It is easier for the children older then 5 years, which causes statistical significance of discrimination to tilt within a narrow margin around 0,05. Reliability of the whole instrument is estimated very high - between 0,86 and 0,91, depending on the method of estimation. However, reliability estimated for particular blocks (grammatical structure revealed that internal consistency of blocks is not homogeneous. This finding prevents reliable estimation of competence for particular structures, and makes difficult to define which contrast is understood by a child and which is not. Furthermore, internal inconsistency of blocks may also be additional source of low discrimination of test for children

    The Columbia River is a critical resource for residents of the Pacific Northwest. This resource drew the Manhattan Project's planners to the site now called Hanford to produce nuclear weapon materials. Production of those materials has left behind a legacy of chemical and radioactive contamination and materials that have, are, and will continue to pose a threat to the Columbia river for the foreseeable future. To evaluate the impact to the river from this Hanford-derived contamination, the US Department of Energy, US Environmental Protection Agency, and State of Washington Department of Ecology (the Tri-Party agencies) initiated a study referred to as the Columbia River Comprehensive Impact Assessment (CRCIA). To address concerns about the scope and direction of CRCIA as well as enhance regulator, stakeholder, tribal, and public involvement, the CRCIA Management Team was formed in August 1995. A major CRCIA Team decision was to organize CRCIA into phases, with additional phases to be identified as warranted after completion of the initial phase. The initial phase is comprised of two parts: (1) a screening assessment to evaluate the current impact to the river resulting from Hanford-derived contamination and (2) identification of requirements considered necessary by the CRCIA Management Team for a comprehensive assessment of impact to the river. The purpose of the screening assessment is to support cleanup decisions. The scope of the screening assessment is to evaluate the current risk to humans and the environment resulting from Hanford-derived contaminants. The screening assessment has the primary components of: identifying contaminants to be assessed; identifying a variety of exposure scenarios to evaluate human contaminant exposure; identifying a variety of other species to evaluate ecological contaminant exposure; and assessing risks posed by exposure of humans and other species to the contaminants

    The study assessed the depth of school disaster safety at public elementary schools in Banda Aceh City, Indonesia in terms of comprehensive school safety, especially school location, disaster management and disaster education. The findings indicate that 56% of public elementary schools in Banda Aceh City are exposed to high tsunami risk, and most externally driven school disaster preparedness activities were not continued by the schools due to lack of ownership and funding. To realize comprehensive school safety, disaster preparedness programs should neither be brought in by external donors, nor be in a patchwork. Rather, it should be conducted jointly and sustainably by the local school and the community and supported by multi-sectoral support in the city. Comprehensive school safety of public elementary schools in Banda Aceh City could be realized by reviewing, updating and localizing school disaster preparedness programs by all the education partners in the city with strong political will and commitment.

    Transmission towers are often subjected to the external damage of severe weather like strong wind and so on, which may cause the collapse due to the yield and fracture of the tower material. Aiming this issue, an assessment method was proposed in this paper to assess the operation condition of transmission towers under strong wind. With a reasonable assess index system established firstly, then the internal force of the tower material was solved and its stability was determined through the mechanical analysis of the transmission tower finite element model. Meanwhile, the condition risk level of the tower was finally determined by considering the difference among the influences of other factors like corrosion and loose of members, slope on the transmission tower through the analytic hierarchy process. The assessment method was applied to assess the wind-induced collapse of towers in 110kV Bao Yi II line in Wenchang City, Hainan Province, of which the result proves the method can assess the condition of transmission tower under strong wind and of guiding significance for improving the windproof capability of transmission towers.

  17. A Comprehensive Evaluation Rubric for Assessing Instructional Apps

    Directory of Open Access Journals (Sweden)

    Cheng-Yuan Lee

    2015-01-01

    Full Text Available There is a pressing need for an evaluation rubric that examines all aspects of educational apps designed for instructional purposes. In past decades, many rubrics have been developed for evaluating educational computer-based programs; however, rubrics designed for evaluating the instructional implications of educational apps are scarce. When an Internet search for existing rubrics was conducted, only two such rubrics were found, and the evaluation criteria used in those rubrics was not clearly linked to previously conducted research nor were their evaluative dimensions clearly defined. These shortcomings result in reviewers being unable to use those rubrics to provide teachers with a precise analysis of an educational app’s instructional potential. In response, this paper presents a comprehensive rubric with 24-evaluative dimensions tailored specifically to analyze the educational potential of instructional apps.

    Brimo, Danielle; Lund, Emily; Sapp, Alysha

    2017-12-18

    Syntax is a language skill purported to support children's reading comprehension. However, researchers who have examined whether children with average and below-average reading comprehension score significantly different on spoken-syntax assessments report inconsistent results. To determine if differences in how syntax is measured affect whether children with average and below-average reading comprehension score significantly different on spoken-syntax assessments. Studies that included a group comparison design, children with average and below-average reading comprehension, and a spoken-syntax assessment were selected for review. Fourteen articles from a total of 1281 reviewed met the inclusionary criteria. The 14 articles were coded for the age of the children, score on the reading comprehension assessment, type of spoken-syntax assessment, type of syntax construct measured and score on the spoken-syntax assessment. A random-effects model was used to analyze the difference between the effect sizes of the types of spoken-syntax assessments and the difference between the effect sizes of the syntax construct measured. There was a significant difference between children with average and below-average reading comprehension on spoken-syntax assessments. Those with average and below-average reading comprehension scored significantly different on spoken-syntax assessments when norm-referenced and researcher-created assessments were compared. However, when the type of construct was compared, children with average and below-average reading comprehension scored significantly different on assessments that measured knowledge of spoken syntax, but not on assessments that measured awareness of spoken syntax. The results of this meta-analysis confirmed that the type of spoken-syntax assessment, whether norm-referenced or researcher-created, did not explain why some researchers reported that there were no significant differences between children with average and below

    2006-12-01

    To perform internal and external evaluations of all 5 medical schools in Bosnia and Herzegovina against international standards. We carried out a 2-stage survey study using the same 5-point Likert scale for internal and external evaluations of 5 medical schools in Bosnia and Herzegovina (Banja Luka, Foca/East Sarajevo, Mostar, Sarajevo and Tuzla). Participants consisted of managerial staff, teaching staff and students of medical schools, and external expert assessors. Main outcome measures included scores on internal and external evaluation forms for 10 items concerning aspects of school curriculum and functioning: 'School mission and objectives'; 'Curriculum'; 'Management'; 'Staff'; 'Students'; 'Facilities and technology'; 'Financial issues'; 'International relationships'; 'Internal quality assurance', and 'Development plans'. During internal assessment, schools consistently either overrated their overall functioning (Foca/East Sarajevo, Mostar and Tuzla) or markedly overrated or underrated their performance on individual items on the survey (Banja Luka and Sarajevo). Scores for internal assessment differed from those for external assessment. These differences were not consistent, except for the sections 'School mission and objectives', 'Curriculum' and 'Development plans', which were consistently overrated in the internal assessments. External assessments was more positive than internal assessments on 'Students' and 'Facilities and technology' in 3 of 5 schools. This assessment exercise in 5 medical schools showed that constructive and structured evaluation of medical education is possible, even in complex and unfavourable conditions. Medical schools in Bosnia and Herzegovina have successfully formed a national consortium for formal collaboration in curriculum development and reform.

    The paper reports a study on an emotionally-loaded dynamic assessment procedure used with Iranian EFL learners. It focuses on the effect of using emotional intelligence characteristics (based on Goleman's framework) as a tool for motivating learners while performing reading tasks. The study with 50 intermediate learners aged 12-15 used three modalities: a control group, which was taught under institute's normal procedures; a comparison group, which received dynamic assessment (DA); and an experimental group, which received emotionalized dynamic assessment (EDA) procedures, in the form of an intervention focusing on characteristics of Goleman's emotional intelligence framework with the express purpose of inducing them to work with their emotions. Results showed that applying EDA procedures to reading assessment tasks made a difference in learners' level of performance in comparison to those who went through pure DA procedures who in turn performed significantly better than those who did not received DA in any form.

    Full Text Available International business demands seamless service and IT-infrastructure throughout the entire supply chain. However, dependencies between different parts of this vulnerable ecosystem form a fragile web. Assessment of the financial effects of any abnormalities in any part of the network is demanded in order to protect this network in a financially viable way. Contractual environment between the actors in a supply chain, different business domains and functions requires a management model, which enables a network wide protection for critical infrastructure. In this paper authors introduce such a model. It can be used to assess financial differences between centralized and decentralized protection of critical infrastructure. As an end result of this assessment business resilience to unknown threats can be improved across the entire supply chain.

    2015-09-01

    With many effective anti-aging solutions for the face, consumer focus is now turning to other parts of the body including the delicate skin on the neck. This study investigates the effect of a new neck cream on the appearance of texture, fine lines and wrinkles, laxity, and hydration. 85 adult females ages 35-65 with Fitzpatrick skin types I through IV applied the test neck cream twice daily for a 3-month study period. Screening was conducted at Baseline, 2, 30, 60, and 90 days via a virtual trial. Subjects rated satisfaction in each of 4 anti-aging categories including hydration, texture, appearance of wrinkles, and appearance of laxity as well as three product attributes including application, feel, and smell. Improvement was statistically significant for all measured categories (hydration, texture, appearance of wrinkles, and appearance of laxity) with 94% of study subjects noting improvement in one or more of the measured categories. Further, the quantity of "Satisfied" and "Highly Satisfied" assessments increased 8-fold from baseline with a 94x increase in the quantity of "Highly Satisfied" assessments. The results demonstrate the product's rapid and continuing ability to improve the self-perceived signs of aging in the neck area including improvement in skin texture on the neck and a reduction in the appearance of wrinkles and laxity along the jawline. Future studies are recommended to determine the primary action mechanisms and to assess the degree of improvement by blinded physician assessment.

Inconsistent recording formats present challenges for primary care providers who must document each child's…

  10. Hydrologic Scenario Uncertainty in a Comprehensive Assessment of Hydrogeologic Uncertainty

    2005-12-01

    A method to jointly assess hydrogeologic conceptual model and parameter uncertainties has recently been developed based on a Maximum Likelihood implementation of Bayesian Model Averaging (MLBMA). Evidence from groundwater model post-audits suggests that errors in the projected future hydrologic conditions of a site (hydrologic scenarios) are a significant source of model predictive errors. MLBMA can be extended to include hydrologic scenario uncertainty, along with conceptual model and parameter uncertainties, in a systematic and quantitative assessment of predictive uncertainty. Like conceptual model uncertainty, scenario uncertainty is represented by a discrete set of alternative scenarios. The effect of scenario uncertainty on model predictions is quantitatively assessed by conducting an MLBMA analysis under each scenario. We demonstrate that posterior model probability is a function of the scenario only through the possible dependence of prior model probabilities on the scenario. As a result, the model likelihoods (computed from calibration results), are not a function of the scenario and do not need to be recomputed under each scenario. MLBMA results for each scenario are weighted by the scenario probability and combined to render a joint assessment of scenario, conceptual model, and parameter uncertainty. Like model probability, scenario probability represents a subjective evaluation, in this case of the plausibility of the occurrence of the specific scenario. Because the scenarios describe future conditions, the scenario probabilities represent prior estimates and cannot be updated using the (past) system state data as is used to compute posterior model probabilities. Assessment of hydrologic scenario uncertainty is illustrated using a site-specific application considering future changes in land use, dam operations, and climate. Estimation of scenario probabilities and consideration of scenario characteristics (e.g., timing, magnitude) are discussed.

  11. Ring Current Dynamics in Moderate and Strong Storms: Comparative Analysis of TWINS and IMAGE/HENA Data with the Comprehensive Ring Current Model

    We present a comparative study of ring current dynamics during strong and moderate storms. The ring current during the strong storm is studied with IMAGE/HENA data near the solar cycle maximum in 2000. The ring current during the moderate storm is studied using energetic neutral atom (ENA) data from the Two Wide-Angle Imaging Neutral- Atom Spectrometers (TWINS) mission during the solar minimum in 2008. For both storms, the local time distributions of ENA emissions show signatures of postmidnight enhancement (PME) during the main phases. To model the ring current and ENA emissions, we use the Comprehensive Ring Current Model (CRCM). CRCM results show that the main-phase ring current pressure peaks in the premidnight-dusk sector, while the most intense CRCM-simulated ENA emissions show PME signatures. We analyze two factors to explain this difference: the dependence of charge-exchange cross section on energy and pitch angle distributions of ring current. We find that the IMF By effect (twisting of the convection pattern due to By) is not needed to form the PME. Additionally, the PME is more pronounced for the strong storm, although relative shielding and hence electric field skewing is well developed for both events.

    There is a strong link between drug use and crime, but this relationship is complex. Drug use does not necessarily lead to an increase in crimes, such as theft, rape or assault, even among regular users or addicts. However, in cases of individuals who consume drugs excessively and commit crimes, both factors are linked. Poverty, personality disorders, social and cultural variables, relationships with other users and previous incarceration or drug use are all factors. These issues play an important role in understanding the risk of crime and drug use. Most addicts should be held liable for most criminal behaviour motivated by addiction, but that addiction can, in some cases, affect one's capacity for self-control over one's actions. This paper examines the current response of the Spanish Criminal Justice System to various aspects of drug abuse, focusing on court decisions related with the nature and enforcement of drug laws. It also addresses aspects of criminal responsibility for drug abuse and drug-related crimes and suggests legislation on drugs, sentencing alternatives for drug offenses, and drug treatment options. Expert evidence plays a crucial role in this area in the court.

    Orthostatic Tremor (OT) is a movement disorder characterized by a sensation of unsteadiness and tremors in the 13-18 Hz range present upon standing. The pathophysiology of OT is not well understood but there is a relationship between the sensation of instability and leg tremors. Despite the sensation of unsteadiness, OT patients do not fall often and balance in OT has not been formally assessed. We present a prospective blinded study comparing balance assessment in patients with OT versus healthy controls. We prospectively enrolled 34 surface Electromyography (EMG)-confirmed primary OT subjects and 21 healthy controls. Participants underwent evaluations of balance by blinded physical therapists (PT) with standardized, validated, commonly used balance scales and tasks. OT subjects were mostly female (30/34, 88%) and controls were majority males (13/20, 65%). The average age of OT subjects was 68.5 years (range 54-87) and for controls was 69.4 (range 32-86). The average duration of OT symptoms was 18 years. OT subjects did significantly worse on all the balance scales and on most balance tasks including Berg Balance Scale, Functional Gait Assessment, Dynamic Gait Index, Unipedal Stance Test, Functional Reach Test and pull test. Gait speed and five times sit to stand were normal in OT. Common validated balance scales are significantly abnormal in primary OT. Despite the objective finding of impaired balance, OT patients do not commonly have falls. The reported sensation of unsteadiness in this patient population seems to be out of proportion to the number of actual falls. Further studies are needed to determine which components of commonly used balance scales are affected by a sensation of unsteadiness and fear of falling. Copyright © 2017 Elsevier Ltd.

    2017-04-20

    In this epilogue, we review the 4 response articles and highlight the implications of a multidimensional view of reading for the assessment and instruction of reading comprehension. We reiterate the problems with standardized tests of reading comprehension and discuss the advantages and disadvantages of recently developed authentic tests of reading comprehension. In the "Instruction" section, we review the benefits and limitations of strategy instruction and highlight suggestions from the response articles to improve content and language knowledge. We argue that the only compelling reason to administer a standardized test of reading comprehension is when these tests are necessary to qualify students for special education services. Instruction should be focused on content knowledge, language knowledge, and specific task and learning requirements. This instruction may entail the use of comprehension strategies, particularly those that are specific to the task and focus on integrating new knowledge with prior knowledge.

    The Fundamentals of Laparoscopic surgery (FLS) is a validated program for the teaching and evaluation of the basic knowledge and skills required to perform laparoscopic surgery. The educational component includes didactic, Web-based material and a simple, affordable physical simulator with specific tasks and a recommended curriculum. FLS certification requires passing a written multiple-choice examination and a proctored manual skills examination in the FLS simulator. The metrics for the FLS program have been rigorously validated to meet the highest educational standards, and certification is now a requirement for the American Board of Surgery. This article summarizes the validation process and the FLS-related research that has been done to date. The Fundamentals of Endoscopic Surgery is a program modeled after FLS with a similar mission for flexible endoscopy. It is currently in the final stages of development and will be launched in April 2010. The program also includes learning and assessment components, and is undergoing the same meticulous validation process as FLS. These programs serve as models for the creation of simulation-based tools to teach skills and assess competence with the intention of optimizing patient safety and the quality of surgical education.

    UU focused on the behavior of trace metals in the combustion zone by studying vaporization from single coal particles. The coals were burned at 1700 K under a series of fuel-rich and oxygen-rich conditions. The data collected in this study will be applied to a model that accounts for the full equilibrium between carbon monoxide and carbon dioxide. The model also considers many other reactions taking place in the combustion zone, and involves the diffusion of gases into the particle and combustion products away from the particle. A comprehensive study has been conducted at UA to investigate the post-combustion partitioning of trace elements during large-scale combustion of pulverized coal combustion. For many coals, there are three distinct particle regions developed by three separate mechanisms: (1) a submicron fume, (2) a micron-sized fragmentation region, and (3) a bulk (>3 {micro}m) fly ash region. The controlling partitioning mechanisms for trace elements may be different in each of the three particle regions. A substantial majority of semi-volatile trace elements (e.g., As, Se, Sb, Cd, Zn, Pb) volatilize during combustion. The most common partitioning mechanism for semi-volatile elements is reaction with active fly ash surface sites. Experiments conducted under this program at UC focused on measuring mercury oxidation under cooling rates representative of the convective section of a coal-fired boiler to determine the extent of homogeneous mercury oxidation under these conditions. In fixed bed studies at EERC, five different test series were planned to evaluate the effects of temperature, mercury concentration, mercury species, stoichiometric ratio of combustion air, and ash source. Ash samples generated at UA and collected from full-scale power plants were evaluated. Extensive work was carried out at UK during this program to develop new methods for identification of mercury species in fly ash and sorbents. We demonstrated the usefulness of XAFS spectroscopy for

    Despite a growing literature on the climate response to solar geoengineering—proposals to cool the planet by increasing the planetary albedo—there has been little published on the impacts of solar geoengineering on natural and human systems such as agriculture, health, water resources, and ecosystems. An understanding of the impacts of different scenarios of solar geoengineering deployment will be crucial for informing decisions on whether and how to deploy it. Here we review the current state of knowledge about impacts of a solar-geoengineered climate and identify the major research gaps. We suggest that a thorough assessment of the climate impacts of a range of scenarios of solar geoengineering deployment is needed and can be built upon existing frameworks. However, solar geoengineering poses a novel challenge for climate impacts research as the manner of deployment could be tailored to pursue different objectives making possible a wide range of climate outcomes. We present a number of ideas for approaches to extend the survey of climate impacts beyond standard scenarios of solar geoengineering deployment to address this challenge. Reducing the impacts of climate change is the fundamental motivator for emissions reductions and for considering whether and how to deploy solar geoengineering. This means that the active engagement of the climate impacts research community will be important for improving the overall understanding of the opportunities, challenges, and risks presented by solar geoengineering.

    The Comprehensive Assessment Battery for Children - Working Memory (CABC-WM) is a computer-based battery designed to assess different components of working memory in young school-age children. Working memory deficits have been identified in children with language-based learning disabilities, including dyslexia 1 , 2 and language impairment 3 , 4 , but it is not clear whether these children exhibit deficits in subcomponents of working memory, such as visuospatial or phonological working memory. The CABC-WM is administered on a desktop computer with a touchscreen interface and was specifically developed to be engaging and motivating for children. Although the long-term goal of the CABC-WM is to provide individualized working memory profiles in children, the present study focuses on the initial success and utility of the CABC-WM for measuring central executive, visuospatial, phonological loop, and binding constructs in children with typical development. Immediate next steps are to administer the CABC-WM to children with specific language impairment, dyslexia, and comorbid specific language impairment and dyslexia.

    Anthropogenic activities like industrial production and transportation, a wide range of chemical pollutants such as trace and toxic metals, pesticides, polycyclic aromatic hydrocarbons etc. eventually found their way into various environmental compartments. These pollutants get distributed among soil, water bodies, air and if left unattended can cause serious health risk to all exposed ecosystem components including human beings. These compounds may produce immediate toxicity to ecosystems or exhibit long term effects such as mutagenicity, carcinogenicity or biomagnify (concentrations of pollutant increase per unit body weight) in higher trophic organism of the food chain. Thus regular monitoring of these toxic chemicals in all the environmental matrices is unquestionably essential for reclaiming our natural resources. This report describes some of the activities of Environmental Assessment Division which are having direct relevance to the public health and regulatory bodies. Extensive studies were carried out in our laboratories for the Trombay site, over the years; on the organic as well as inorganic pollution in the environment to understand inter compartmental behaviour of these chemical pollutants. In this report attempt has been made to compare the data on various toxic chemical pollutants that are being monitored regularly at Trombay site and their levels are compared with existing regulations. For monitoring, methodologies have been standardized for characterization of toxic chemical pollutants using different analytical techniques. Regular sample collection from different environmental matrices has been done. Sample analysis has been carried out using different analytical instruments such as high performance liquid chromatograph, ion chromatograph, gas chromatograph, atomic absorption spectrophotometer, and differential pulse anodic stripping voltammetry. Major portion of the study covers Air quality monitoring of toxic chemical pollutants, as the other

    While in active operation from 1952 until 1989, the Feed Material Production Center (FMPC),currently referred to as the Fernald Environmental Management Project (FEMP), produced highly purified uranium metal for ultimate use in the manufacture of nuclear weapons. In 1986 the U.S. Environmental Protection Agency (EPA) and the DOE entered into a Federal Facility Compliance Agreement covering environmental impacts associated with the FMPC. In response to the FFCA, a sitewide Remedial Investigation/Feasibility Study (RI/FS) was initiated. Production was permanently suspended at the facility in 1989, and the focus has since shifted to environmental restoration and waste management activities. The original RI/FS work plan identified 39 units, but these were later categorized and grouped into 5 larger, more manageable units as follows: (1) operable unit 1 - waste pit area; (2) operable unit 2 - other solid waste units; (3) operable unit 3 - former production area; (4) operable unit 4- silos I through 4; and (5) operable unit 5 - environmental media. On June 29, 1990, a consent agreement (under Sec. 120 and 106[a] of CERCLA) between the DOE and EPA became effective. The purpose of this agreement was to achieve consistency between the operable units and ensure commitments to the RI/FS program without altering the underlying objectives. The consent agreement was amended the following year to revise the schedules for completing the remediation of the five operable units and to direct operable unit integration to ensure compliance with the residual risk requirements of the National Hazardous Substances and Oil Contingency Plan. This Amended Consent Agreement (ACA) was signed on September 20, 1991, and became effective on December 19, 1991. In accordance with provisions of the ACA, a methodology has been prepared for performing risk assessments and establishing risk-based remedial action goals at the FEMP

    We examine the economic consequences of strong earthquakes by example of M9 Tahoku one that occurred on March 11, 2011 close to the northeast shore of Japanese coast Honshu. This earthquake became the strongest in the whole history of the seismological observations in this part of the planet. The generated tsunami killed more than 15,700 people, damaged 332,395 buildings and 2,126 roads. The total economic loss in Japan was estimated at 309 billion. The catastrophe in Japan also impacted global economy. To estimate its impact, we used regional and global stock indexes, production indexes, stock prices of the main Japanese, European and US companies, import and export dynamics, as well as the data provided by the custom of Japan. We also demonstrated that the catastrophe substantially affected the markets and on the short run in some indicators it even exceeded the effect of the global financial crisis of 2008. The last strong earthquake occurred in Nepal (25.04.2015, M7.8) and Chile (16.09.2015, M8.3), both actualized the research of cost assessments of the overall economic impact of seismic hazard. We concluded that it is necessary to treat strong earthquakes as one very important factor that affects the world economy depending on their location. The research was supported by Russian Foundation for Basic Research (Project 16-06-00056A).

    In Ethiopia, more adolescents are in school today than ever before; however, there are no studies that have assessed their comprehensive knowledge of HIV/AIDS. Thus, this study tried to assess the level of this knowledge and the factors associated with it among in-school adolescents in eastern Ethiopia. A cross-sectional school-based study was conducted using a facilitator-guided self-administered questionnaire. The respondents were students attending regular school in 14 high schools located in 14 different districts in eastern Ethiopia. The proportion of in-school adolescents with comprehensive HIV/AIDS knowledge was computed and compared by sex. The factors that were associated with the comprehensive HIV/AIDS knowledge were assessed using bivariate and multivariable logistic regression. Only about one in four, 677 (24.5%), in-school adolescents have comprehensive HIV/AIDS knowledge. The knowledge was better among in-school adolescents from families with a relatively middle or high wealth index (adjusted OR [95% CI]=1.39 [1.03-1.87] and 1.75 [1.24-2.48], respectively), who got HIV/AIDS information mainly from friends or mass media (adjusted OR [95% CI]=1.63 [1.17-2.27] and 1.55 [1.14-2.11], respectively) and who received education on HIV/AIDS and sexual matters at school (adjusted OR [95% CI]=1.59 [1.22-2.08]). The females were less likely to have comprehensive HIV/AIDS knowledge compared to males (adjusted OR and [95% CI]=0.60 [0.49-0.75]). In general, only about a quarter of in-school adolescents had comprehensive HIV/AIDS knowledge. Although the female adolescents are highly vulnerable to HIV infection and its effects, they were by far less likely to have comprehensive HIV/AIDS knowledge. HIV/AIDS information, education and communication activities need to be intensified in high schools.

  7. Seismic rupture modelling, strong motion prediction and seismic hazard assessment: fundamental and applied approaches

    Berge-Thierry, C.

    2007-05-01

    The defence to obtain the 'Habilitation a Diriger des Recherches' is a synthesis of the research work performed since the end of my Ph D. thesis in 1997. This synthesis covers the two years as post doctoral researcher at the Bureau d'Evaluation des Risques Sismiques at the Institut de Protection (BERSSIN), and the seven consecutive years as seismologist and head of the BERSSIN team. This work and the research project are presented in the framework of the seismic risk topic, and particularly with respect to the seismic hazard assessment. Seismic risk combines seismic hazard and vulnerability. Vulnerability combines the strength of building structures and the human and economical consequences in case of structural failure. Seismic hazard is usually defined in terms of plausible seismic motion (soil acceleration or velocity) in a site for a given time period. Either for the regulatory context or the structural specificity (conventional structure or high risk construction), seismic hazard assessment needs: to identify and locate the seismic sources (zones or faults), to characterize their activity, to evaluate the seismic motion to which the structure has to resist (including the site effects). I specialized in the field of numerical strong-motion prediction using high frequency seismic sources modelling and forming part of the IRSN allowed me to rapidly working on the different tasks of seismic hazard assessment. Thanks to the expertise practice and the participation to the regulation evolution (nuclear power plants, conventional and chemical structures), I have been able to work on empirical strong-motion prediction, including site effects. Specific questions related to the interface between seismologists and structural engineers are also presented, especially the quantification of uncertainties. This is part of the research work initiated to improve the selection of the input ground motion in designing or verifying the stability of structures. (author)

    The purpose of this study was to assess the effectiveness of a team-based educational program designed to enhance the flow of applied, research-based, nutrition information to dairy veterinarians. A comprehensive dairy cattle nutrition curriculum was developed and participants from 11 veterinary practices located in 5 states (IN, NY, PA, NM, and OH), serving an estimated 186,150 dairy cattle in 469 herds, attended the 2 advanced nutrition modules (∼2.5 d each and ∼40 h of learning) held in 2009. Nutrients, feeding transition cows, calves, and heifers, dry matter intake, feed storage, metabolic diseases, evaluating cows (scoring body condition, manure, and lameness), metabolic blood profiles, and feeding behavior were discussed. Educational materials were delivered through in-class lectures, followed by case-based learning and group discussions. A farm visit and out-of-class assignments were also implemented. Attendees were assessed using pre- and post-tests of knowledge to determine the level of knowledge gained in both nutrition modules. Participants evaluated the program and provided feedback at the conclusion of each module. Veterinarians (100%) reported that the overall program, presentations, and discussions were useful. Attendees found the presented information relevant for their work (agree=60% and strongly agree=40%) and of great immediate use to them (neutral=6.5%, agree=56%, and strongly agree=37.5%). The presented materials and the implemented educational delivery methods substantially increased the knowledge level of the attendees (16.9% points increase from pre-test to post-test scores). Importance of feed particle size, ration evaluation, interpreting feed analysis, balancing carbohydrate components, and metabolic profiling in fresh cows were listed as learned concepts that participants could apply in their practices. Results suggested that both nutrition modules were relevant and effective, offering new information with immediate field

    2009-11-24

    Baylor University Center for Reservoir and Aquatic Systems Research (CRASR) has conducted a phased, comprehensive evaluation of Lake Whitney to determine its suitability for use as a regional water supply reservoir. The area along the Interstate 35 corridor between Dallas / Fort Worth Metroplex and the Waco / Temple Centroplex represents one of the fastest growth areas in the State of Texas and reliable water supplies are critical to sustainable growth. Lake Whitney is situated midway between these two metropolitan areas. Currently, the City of Whitney as well as all of Bosque and Hill counties obtain their potable water from the Trinity Sands aquifer. Additionally, parts of the adjoining McLennan and Burleson counties utilize the Trinity sands aquifer system as a supplement to their surface water supplies. Population growth coupled with increasing demands on this aquifer system in both the Metroplex and Centroplex have resulted in a rapid depletion of groundwater in these rural areas. The Lake Whitney reservoir represents both a potentially local and regional solution for an area experiencing high levels of growth. Because of the large scope of this project as well as the local, regional and national implications, we have designed a multifaceted approach that will lead to the solution of numerous issues related to the feasibility of using Lake Whitney as a water resource to the region. Phase IA (USEPA, QAPP Study Elements 1-4) of this research focused on the physical limnology of the reservoir (bathymetry and fine scale salinity determination) and develops hydrodynamic watershed and reservoir models to evaluate how salinity would be expected to change with varying hydrologic and climatic factors. To this end, we implemented a basic water quality modeling program in collaboration with the Texas Parks and Wildlife Department and the Texas Commission on Environmental Quality to add to the developing long-term database on Lake Whitney. Finally, we conducted an initial

    Verbs and sentences are often impaired in individuals with aphasia, and differential impairment patterns are associated with different types of aphasia. With currently available test batteries, however, it is challenging to provide a comprehensive profile of aphasic language impairments because they do not examine syntactically important properties of verbs and sentences. This study presents data derived from the Northwestern Assessment of Verbs and Sentences (NAVS; Thompson, 2011), a new test battery designed to examine syntactic deficits in aphasia. The NAVS includes tests for verb naming and comprehension, and production of verb argument structure in simple active sentences, with each examining the effects of the number and optionality of arguments. The NAVS also tests production and comprehension of canonical and non-canonical sentences. A total of 59 aphasic participants (35 agrammatic and 24 anomic) were tested using a set of action pictures. Participants produced verbs or sentences for the production subtests and identified pictures corresponding to auditorily provided verbs or sentences for the comprehension subtests. The agrammatic group, compared to the anomic group, performed significantly more poorly on all subtests except verb comprehension, and for both groups comprehension was less impaired than production. On verb naming and argument structure production tests both groups exhibited difficulty with three-argument verbs, affected by the number and optionality of arguments. However, production of sentences using three-argument verbs was more impaired in the agrammatic, compared to the anomic, group. On sentence production and comprehension tests, the agrammatic group showed impairments in all types of non-canonical sentences, whereas the anomic group exhibited difficulty primarily with the most difficult, object relative, structures. Results show that verb and sentence deficits seen in individuals with agrammatic aphasia are largely influenced by

    Reading comprehension assessment should rely on valid instruments that enable adequate conclusions to be taken regarding students' reading comprehension performance. In this article, two studies were conducted to collect validity evidence for the vertically scaled forms of two Tests of Reading Comprehension for Portuguese elementary school students in the second to fourth grades, one with narrative texts (TRC-n) and another with expository ones (TRC-e). Two samples of 950 and 990 students participated in Study 1, the study of the dimensionality of the TRC-n and TRC-e forms, respectively. Confirmatory factor analyses provided evidence of an acceptable fit for the one-factor solution for all test forms. Study 2 included 218 students to collect criterion-related validity. The scores obtained in each of the test forms were significantly correlated with the ones obtained in other reading comprehension measures and with the results obtained in oral reading fluency, vocabulary and working memory tests. Evidence suggests that the test forms are valid measures of reading comprehension. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Flood is a serious challenge that increasingly affects the residents as well as policymakers. Flood vulnerability assessment is becoming gradually relevant in the world. The purpose of this study is to develop an approach to reveal the relationship between exposure, sensitivity and adaptive capacity for better flood vulnerability assessment, based on the fuzzy comprehensive evaluation method (FCEM) and coordinated development degree model (CDDM). The approach is organized into three parts: establishment of index system, assessment of exposure, sensitivity and adaptive capacity, and multiple flood vulnerability assessment. Hydrodynamic model and statistical data are employed for the establishment of index system; FCEM is used to evaluate exposure, sensitivity and adaptive capacity; and CDDM is applied to express the relationship of the three components of vulnerability. Six multiple flood vulnerability types and four levels are proposed to assess flood vulnerability from multiple perspectives. Then the approach is applied to assess the spatiality of flood vulnerability in Hainan's eastern area, China. Based on the results of multiple flood vulnerability, a decision-making process for rational allocation of limited resources is proposed and applied to the study area. The study shows that multiple flood vulnerability assessment can evaluate vulnerability more completely, and help decision makers learn more information about making decisions in a more comprehensive way. In summary, this study provides a new way for flood vulnerability assessment and disaster prevention decision. Copyright © 2018 Elsevier Ltd. All rights reserved.

  3. Assessment of Sustainability of Urban Water Supply and Demand Management Options: A Comprehensive Approach

    2016-12-01

    Full Text Available A comprehensive evaluation framework that can assess a wide range of water supply and demand management policy options in terms of economic, social, environmental, risk-based, and functional performance is crucial to ascertain their level of sustainability. However, such a detailed, generic, and holistic policy evaluation framework is not found in the literature. This paper reviews studies to evaluate water supply and/or demand management options conducted during 2000–2016. Primarily, the paper reviews the evaluation criteria used by different studies for decision making given their significant difference and the importance of a comprehensive set of criteria to complete a rigorous evaluation. In addition, a comprehensive set of water supply and demand management options are not considered together for a comparative assessment to prioritise best options for a certain area and time. Further, performance of these options needs to be evaluated for a range of uncertainties arising from changes of spatial and temporal variables of the system. While this paper highlights the important aspects that need to be included in a comprehensive policy evaluation framework, available studies collectively present a rich set of information to support it.

  4. Probabilistic safety assessment. A systematic and comprehensive method to evaluate risk

    Probabilistic safety assessment (PSA) is a systematic and comprehensive methodology to evaluate risks with every life-cycle aspect of a complex engineered technological entity such as a chemical facility, a spacecraft or a nuclear power plant. PSA can help to identify possible weaknesses of the plant design but also to provide insights into the existing safety margins for event sequences exceeding the design limits. A further benefit of PSA in this context is to show the existing safety margins correlating the original design criteria and boundary conditions and the real operating experience (e.g. by comparing the expected loads on structures, systems and components with the actual situation since a lot of years of operation). In that sense PSA is a very useful tool to complement deterministic insights in safety evaluation, as far its quality, scope and documentation is sufficient, and a strong co-ordination between both areas exist. At present, probabilistic tools to support the safety assessment of operating nuclear power plants built to earlier standards and/or the judgement of the safety relevance of certain back fitting measures are applied by the utilities, experts and regulators. Therefore, most operating nuclear power plants worldwide have been studied using PSA methods. Usually, a level 1 internal events PSA has been performed on all plants. In the last years, in some countries this has been extended to a level 1, also investigating some external hazards, or a level 2 PSA. However, in several cases the level 2 PSA is limited to the determination of the large early release frequency and is not a complete Level 2 analysis of plant damage states. The importance to use PSA already in the design phase of a nuclear power plant is growing because the model combines front-line safety systems and support systems in a manner that allows designers to determine the risk importance of structures, systems and components, to classify the respective requirements and to

    In many countries, biodiversity compensation is required to counterbalance negative impacts of development projects on biodiversity by carrying out ecological measures, called offset when the goal is to reach "no net loss" of biodiversity. One main issue is to ensure that offset gains are equivalent to impact-related losses. Ecological equivalence is assessed with ecological equivalence assessment methods taking into account a range of key considerations that we summarized as ecological, spatial, temporal, and uncertainty. When equivalence assessment methods take into account all considerations, we call them "comprehensive". Equivalence assessment methods should also aim to be science-based and operational, which is challenging. Many equivalence assessment methods have been developed worldwide but none is fully satisfying. In the present study, we examine 13 equivalence assessment methods in order to identify (i) their general structure and (ii) the synergies and trade-offs between equivalence assessment methods characteristics related to operationality, scientific-basis and comprehensiveness (called "challenges" in his paper). We evaluate each equivalence assessment methods on the basis of 12 criteria describing the level of achievement of each challenge. We observe that all equivalence assessment methods share a general structure, with possible improvements in the choice of target biodiversity, the indicators used, the integration of landscape context and the multipliers reflecting time lags and uncertainties. We show that no equivalence assessment methods combines all challenges perfectly. There are trade-offs between and within the challenges: operationality tends to be favored while scientific basis are integrated heterogeneously in equivalence assessment methods development. One way of improving the challenges combination would be the use of offset dedicated data-bases providing scientific feedbacks on previous offset measures.

    Small populations are more prone to extinction if the dispersal among them is not adequately maintained by ecological connections. The degree of isolation between populations could be evaluated measuring their genetic distance, which depends on the respective geographic (isolation by distance, IBD) and/or ecological (isolation by resistance, IBR) distances. The aim of this study was to assess the ecological connectivity of fire salamander Salamandra salamandra populations by means of a landscape genetic approach. The species lives in broad-leaved forest ecosystems and is particularly affected by fragmentation due to its habitat selectivity and low dispersal capability. We analyzed 477 biological samples collected in 47 sampling locations (SLs) in the mainly continuous populations of the Prealpine and Eastern foothill lowland (PEF) and 10 SLs in the fragmented populations of the Western foothill (WF) lowland of Lombardy (northern Italy). Pairwise genetic distances (Chord distance, DC) were estimated from allele frequencies of 16 microsatellites loci. Ecological distances were calculated using one of the most promising methodology in landscape genetics studies, the circuit theory, applied to habitat suitability maps. We realized two habitat suitability models: one without barriers (EcoD) and a second one accounting for the possible barrier effect of main roads (EcoDb). Mantel tests between distance matrices highlighted how the Log-DC in PEF populations was related to log-transformed geographic distance (confirming a prevalence of IBD), while it was explained by the Log-EcoD, and particularly by the Log-EcoDb, in WF populations, even when accounting for the confounding effect of geographic distance (highlighting a prevalence of IBR). Moreover, we also demonstrated how considering the overall population, the effect of Euclidean or ecological distances on genetic distances acting at the level of a single group (PEF or WF populations) could not be detected, when

    Full Text Available Analysis of the cost-effectiveness of 29 Comprehensive School Reform (CSR models suggests that all 29 models are less cost-effective than an alternative approach for raising student achievement, involving rapid assessment systems that test students 2 to 5 times per week in math and reading and provide rapid feedback of the results to students and teachers. Results suggest that reading and math achievement could increase approximately one order of magnitude greater for every dollar invested in rapid assessment rather than CSR. The results also suggest that reading and math achievement could increase two orders of magnitude for every dollar invested in rapid assessment rather than class size reduction and three orders of magnitude for every dollar invested in rapid assessment rather than high quality preschool.

  10. Considerations on comprehensive risk assessment and mitigation planning of volcanic ash-fall

    2010-01-01

    Volcanic ash-fall is inevitable hazard throughout Japan, and causes wide range of effects due to its physical and chemical properties. Nuclear power plants in Japan face the necessity to assess the risk from volcanic ash-fall. Risk assessment of the volcanic ash-fall should include engineering solution and mitigation planning as well as the ash-fall hazard. This report points out the characteristics for reducing the various effects of volcanic ash-fall as follows. Large-scale eruptions produce prominent volcanic ash-falls that can approach power plants at a great distance. Aftermath hazards of ash-fall events, such as remobilization of fine ash particles and generation of lahars, require further assessments. The kind and extent of damages becomes greater whenever ash is wet. Wet ash requires separate assessments in contrast to dry ash. The mitigation and recovery measures at power plants involve quick cleanup operations of volcanic ash. Those operations should be prepared through comprehensive risk assessment, and by cooperation with authorities, during pre-eruption repose period. The comprehensive assessment for volcanic ash-fall hazards, however, has yet to be conducted. Development of risk communication method may result in increased implementation mitigation planning. Numerical analysis of the ash-fall hazards provides quantitative data on particle motions that can be used in the risk assessment. In order to implement the quantitative assessment method, the verification on the effect of ambient air condition to the altitude of volcanic ash cloud is necessary. We need to develop a three-dimensional model of volcanic ash cloud, and calculate motions of ash clouds under multiple conditions of ambient air. (author)

    Because of past nuclear production operations along the Columbia River, there is intense public and tribal interest in assessing any residual Hanford Site related contamination along the river from the Hanford Reach to the Pacific Ocean. The Columbia River Impact Assessment (CRCIA) was proposed to address these concerns. The assessment of the Columbia River is being conducted in phases. The initial phase is a screening assessment of risk, which addresses current environmental conditions for a range of potential uses. One component of the screening assessment estimates the risk from contaminants in the Columbia River to humans. Because humans affected by the Columbia river are involved in a wide range of activities, various scenarios have been developed on which to base the risk assessments. The scenarios illustrate the range of activities possible by members of the public coming in contact with the Columbia River so that the impact of contaminants in the river on human health can be assessed. Each scenario illustrates particular activity patterns by a specific group. Risk will be assessed at the screening level for each scenario. This report defines the scenarios and the exposure factors that will be the basis for estimating the potential range of risk to human health from Hanford-derived radioactive as well as non-radioactive contaminants associated with the Columbia River.

    1990-05-01

    The U.S. Department of Energy (DOE) has placed strong emphasis on a new way of doing business patterned on the lessons learned in the nuclear power industry after the accident at Three Mile Island Unit 2. The new way relies on strict adherence to policies and procedures, a greatly expanded training program, and much more rigor and formality in operations. Another key element is more visible oversight by upper management and auditability by DOR Although the Chemical Technology Division (Chem Tech) has functioned in a safe manner since its beginning, the policies and methods of the past are no longer appropriate. Therefore, in accordance with these directives, Chem Tech is improving its operational performance by making a transition to greater formality in the observance of policies and procedures and a more deliberate consideration of the interrelationships between organizations at ORNL. This transition to formality is vitally important because both our staff and our facilities are changing with time. For example, some of the inventors and developers of the processes and facilities in use are now ''passing the torch'' to the next generation of Chem Tech staff. Our faculties have also served us well for many years, but the newest of these are now over 20 years old. All have increasing needs of refurbishment and repair, and some of the older ones need to be replaced. The Comprehensive Self-Assessment and Upgrade Program (CSAUP) has been patterned on a similar activity performed at the High Flux Isotope Reactor. Using the Draft DOE Performance Objectives and Criteria for Technical Safety Appraisals (May 1987) as a starting point, it was determined that 14 functional areas for evaluation listed in the report were suitable for Chem Tech use. An additional 5 functional areas were added for completeness since Chem Tech has a broader set of missions than a reactor facility. The Performance Objectives and Criteria (POC) for each functional area in the DOE report were

    : Environment functions in various aspects including soil and water conservation, biodiversity and habitat, aesthetics, etc. Comprehensive assessment of environmental quality thus is a great challenge. The issues include how to assess individual functions of environment such as landscape aesthetics and how to integrate them into an indicator that can be used to comprehensively quantifying environmental quality. In this study, remote sensing, geographic information systems (GIS), and spatial multi-criteria decision analysis methods were combined to create an integrated indicator. This approach was applied to a case study in which land condition and its dynamics due to military training activities was assessed. The indicator was derived based on soil erosion, water quality, noise, and spatial metrics that measure landscape fragmentation and aesthetics. The results showed that landscape level indicator well quantified the overall environmental health and its dynamics, while the patch level indicator detailed the local environmental quality. The environmental quality was mostly determined by soil erosion, then landscape fragmentation, water quality, aesthetics, and noise. Moreover, both landscape shape index (LSI) and Aggregation Index (AI) had significant correlation with military training intensity and quantified the landscape fragmentation. Without doubt, this study provided effective tools for army land managers to accurately analyze environmental dynamics. It is also expected this approach can be applied to environmental management of other lands.

    Full Text Available Derived from Vygotsky’s works, dynamic assessment (DA enables learners to move beyond their current level of functioning through offering needs-sensitized mediation. This study aimed at exploring the learners’ development in novel and increasingly more challenging situations called transcendence (TR in an L2 context focusing on reading comprehension through computerized dynamic assessment (CDA. An overall number of 32 BA TEFL advanced students were selected from among undergraduates of a university in Iran to participate in this study. To fulfil the purpose of the study, the researchers developed Computerized Dynamic Reading Assessment to examine Transcendence (CDRAT software which included reading comprehension CDA tests. To monitor the maintenance of learning in different time intervals, two software programs named CDRAT1 and CDRAT2 were utilized in specific time intervals after the posttest. The results indicated that not only did increased task complexity not lead to regression of students’ development, but also it had an effect on enhancing their development. Thus, transcendence had an effect on the generalizability of the contentions to a great extent. In conclusion, it was disclosed that there is no endpoint to progress and merely gaining a low or high score should not be interpreted as the inability of a special learner to surpass. This would more reinforce the need for applying TR in other future DA studies.

    Groundwater contamination is a serious threat to water supply. Risk assessment of groundwater contamination is an effective way to protect the safety of groundwater resource. Groundwater is a complex and fuzzy system with many uncertainties, which is impacted by different geological and hydrological factors. In order to deal with the uncertainty in the risk assessment of groundwater contamination, we propose an approach with analysis hierarchy process and fuzzy comprehensive evaluation integrated together. Firstly, the risk factors of groundwater contamination are identified by the sources-pathway-receptor-consequence method, and a corresponding index system of risk assessment based on DRASTIC model is established. Due to the complexity in the process of transitions between the possible pollution risks and the uncertainties of factors, the method of analysis hierarchy process is applied to determine the weights of each factor, and the fuzzy sets theory is adopted to calculate the membership degrees of each factor. Finally, a case study is presented to illustrate and test this methodology. It is concluded that the proposed approach integrates the advantages of both analysis hierarchy process and fuzzy comprehensive evaluation, which provides a more flexible and reliable way to deal with the linguistic uncertainty and mechanism uncertainty in groundwater contamination without losing important information.

    A comprehensive radioecological and nonradiological characterization and hazards assessment was conducted on DOE-Niagara Falls Storage Site. Pitchblende residues and other low-level nuclear waste have been stored on the site since 1944. The most highly radioactive residues were stored in four abandoned buildings, while other wastes were deposited in pits or piled on surface soils on the Site. Several ditches were constructed on the Site to facilitate drainage or excess precipitation. Results of the study will permit the US DOE to form an appropriate remedial action plan for the Site

    We describe a comprehensive software-oriented approach to virtual reality-based neuroscientific systems in order to establish an easy to use framework for neuroscientific assessment and treatment. We have defined a process model and implemented the NeuroVRAC authoring tool for design and execution of experiments in virtual environments. Our system enables the modeling of virtual world objects and the definition of events, which are used to control the experimental process. We have included the virtual test person concept to enhance the sense of presence during the execution of virtual reality-based neuroscientific experiments.

    Eco-design is an advanced design approach which plays an important part in the national innovation project and serves as a key point for the successful transformation of the supply structure. However, the practical implementation of the pro-environmental designs and technologies always faces a dilemma situation, where some processes can effectively control their emissions to protect the environment at relatively high costs, while others pursue the individual interest in making profit by ignoring the possible adverse environmental impacts. Thus, the assessment on the eco-design process must be carried out based on the comprehensive consideration of the economic and environmental aspects. Presently, the assessment systems in China are unable to fully reflect the new environmental technologies regarding their innovative features or performance. Most of the assessment systems adopt scoring method based on the judgments of the experts, which are easy to use but somewhat subjective. The assessment method presented in this paper includes the environmental impact (EI) assessment based on LCA principal and willingness-to-pay theory, and economic profit (EP) assessment mainly based on market price. The results from the assessment are in the form of EI/EP, which evaluate the targeted process from a combined perspective of environmental and economic performance. A case study was carried out upon the utilization process of coal fly ash, which indicates the proposed method can compare different technical processes in an effective and objective manner, and provide explicit and insightful suggestions for decision making.

    Literature supports the use of point-ofcare ultrasound performed by the treating hospitalist in the diagnosis of common diseases. There is no consensus on the training paradigm or the evaluation of skill retention for hospitalists. To evaluate the effectiveness of a comprehensive bedside ultrasound training program with postcourse competency assessments for hospitalists. A retrospective report of a training program with 53 hospitalists. The program consisted of online modules, a 3-day in-person course, portfolios, 1-day refresher training, monthly scanning, and assessments. Hospitalists were rated by using similar pre- and postcourse competency assessments and self-rating parameters during the 3-day and refresher courses. A large tertiary-care center. Skills increased after the 3-day course from a median preassessment score of 15% correct (interquartile range [IQR] 10%-25%) to a median postassessment score of 90% (IQR 80%-95%; P < .0001). At the time of the refresher course, the median precourse skills score had decreased to 65% correct (IQR 35%-90%), which improved to 100% postcourse (IQR 85%-100%; P < .0001). Skills scores decreased significantly less between the post 3-day course assessment and pre 1-day refresher course for hospitalists who completed portfolios (mean decrease 13.6% correct; P < .0001) and/or monthly scanning sessions (mean decrease 7.3% correct; P < .0001) compared with hospitalists who did not complete these items. A comprehensive longitudinal ultrasound training program including competency assessments improved ultrasound acquisition skills with hospitalists. Skill retention remained high in those who completed portfolios and/or monthly scanning sessions along with a 1-day in-person refresher course.

    To determine family-reported psychosocial stressors and social worker assessments and interventions within a comprehensive cleft team. Single-institution prospective provider-completed survey. Four hundred one families seen by cleft team social worker over a 7-month period. Most families (n = 331; 83%) participated in the team social work assessment. At least 1 active psychosocial stressor was reported by 238 (72%) families, with 63 (19%) families reported 3 or more stressors. There were 34 types of stressors reported. Most common were financial strain, young age of patient, new cleft diagnosis, and distance from clinic (57% of families live over an hour away). Family structure and home environment were assessed in detail for 288 (87%) families. Detailed assessments for access to care and behavioral/developmental issues also figured prominently. Social work interventions were provided in 264 (80%) of the visits, of which 91 were for families of new patients with over half who had infants less than 3 months old. Of the 643 interventions provided, the most frequent were parent mental health screens and counseling, early intervention referrals, transportation assistance, securing local hotel discounts, orthodontic referrals, and orthodontic cost coverage. Approximately 10% of encounters required follow-up contact related to the psychosocial concerns identified in clinic. The inclusion of a cleft team social worker is a critical component of comprehensive cleft team care as evidenced by the large proportion of families who required assistance. Ongoing social work assessments are recommended for each patient to help address the variety of psychosocial stressors families face.

    As an important part of national energy supply system, transmission pipelines for natural gas are possible to cause serious environmental pollution, life and property loss in case of accident. The third party damage is one of the most significant causes for natural gas pipeline system accidents, and it is very important to establish an effective quantitative risk assessment model of the third party damage for reducing the number of gas pipelines operation accidents. Against the third party damage accident has the characteristics such as diversity, complexity and uncertainty, this paper establishes a quantitative risk assessment model of the third party damage based on Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE). Firstly, risk sources of third party damage should be identified exactly, and the weight of factors could be determined via improved AHP, finally the importance of each factor is calculated by fuzzy comprehensive evaluation model. The results show that the quantitative risk assessment model is suitable for the third party damage of natural gas pipelines and improvement measures could be put forward to avoid accidents based on the importance of each factor.

    Post graduate learning and assessment is an important responsibility of an academic oral and maxillofacial surgeon. The current method of assessment for post graduate training include formative evaluation in the form of seminars, case presentations, log books and infrequently conducted end of year theory exams. End of the course theory and practical examination is a summative evaluation which awards the degree to the student based on grades obtained. Oral and maxillofacial surgery is mainly a skill based specialty and deliberate practice enhances skill. But the traditional system of assessment of post graduates emphasizes their performance on the summative exam which fails to evaluate the integral picture of the student throughout the course. Emphasis on competency and holistic growth of the post graduate student during training in recent years has lead to research and evaluation of assessment methods to quantify students' progress during training. Portfolio method of assessment has been proposed as a potentially functional method for post graduate evaluation. It is defined as a collection of papers and other forms of evidence that learning has taken place. It allows the collation and integration of evidence on competence and performance from different sources to gain a comprehensive picture of everyday practice. The benefits of portfolio assessment in health professions education are twofold: it's potential to assess performance and its potential to assess outcomes, such as attitudes and professionalism that are difficult to assess using traditional instruments. This paper is an endeavor for the development of portfolio method of assessment for post graduate student in oral and maxillofacial surgery.

    Comprehensive continuing veterinary medical education (CVME) programs are critical for veterinary practitioners to update their knowledge and improve their skills and services. CVME must offer an educational environment in which veterinarians can effectively rejuvenate their knowledge and skills and learn about new practices. The Ohio Dairy Health and Management Certificate Program is a comprehensive CVME program for practicing dairy veterinarians that was developed to provide advanced training on previously identified needs of the dairy industry. Our objectives in this article were (1) to provide a description of a comprehensive CVME program designed to enhance the flow of applied, research-based knowledge from educators and researchers to dairy veterinary practitioners and (2) to provide an assessment of outcomes achieved and experiences gained after the delivery of the first two modules on advanced dairy reproductive management. Findings from the two reproductive modules suggested that (1) the designed dairy reproductive management program was able to meet the participants' educational needs, (2) the implemented delivery methods significantly increased participants' knowledge level, and (3) additional educational needs should be addressed with future programming. In conclusion, results from the participants' self-reports suggested that both reproductive modules were relevant and effective, offering new information with immediate field application. These types of educational programs are important for dairy veterinary practitioners because they are a vital source of information and service providers for dairy producers. For the program to be considered completely successful, a detailed follow-up assessment of participants' behavior change, adoption of new practices and skills, and their on-farm impact is needed.

    Diagnostic testing often assesses the cardiovascular or respiratory systems in isolation, ignoring the major pathophysiologic interactions between the systems in many diseases. When both systems are assessed currently, multiple modalities are utilized in costly fashion with burdensome logistics and decreased accessibility. Thus, we have developed a new acquisition and reconstruction paradigm using the flexibility of MRI to enable a comprehensive exam from a single 5-15 min scan. We constructed a compressive-sensing approach to pseudo-randomly acquire highly subsampled, multi-dimensionally-encoded and time-stamped data from which we reconstruct volumetric cardiac and respiratory motion phases, contrast-agent dynamics, and blood flow velocity fields. The proposed method, named XD flow, is demonstrated for (a) evaluating congenital heart disease, where the impact of bulk motion is reduced in a non-sedated neonatal patient and (b) where the observation of the impact of respiration on flow is necessary for diagnostics; (c) cardiopulmonary imaging, where cardiovascular flow, function, and anatomy information is needed along with pulmonary perfusion quantification; and in (d) renal function imaging, where blood velocities and glomerular filtration rates are simultaneously measured, which highlights the generality of the technique. XD flow has the ability to improve quantification and to provide additional data for patient diagnosis for comprehensive evaluations.

    As the essential components in formulations, pharmaceutical excipients directly affect the safety, efficacy, and stability of drugs. Recently, safety incidents of pharmaceutical excipients posing seriously threats to the patients highlight the necessity of controlling the potential risks. Hence, it is indispensable for the industry to establish an effective risk assessment system of supply chain. In this study, an AHP-fuzzy comprehensive evaluation model was developed based on the analytic hierarchy process and fuzzy mathematical theory, which quantitatively assessed the risks of supply chain. Taking polysorbate 80 as the example for model analysis, it was concluded that polysorbate 80 for injection use is a high-risk ingredient in the supply chain compared to that for oral use to achieve safety application in clinic, thus measures should be taken to control and minimize those risks.

    The vulnerability assessment of power grid is of great significance in the current research. Power system faces many kinds of uncertainty factors, and the disturbance caused by them has become one of the main factors which restrict the safe operation of power grid. To solve this problem, considering the anti-interference ability of the system when the system is disturbed and the effect of the system when the node is out of operation, a set of index to reflect the anti-interference ability and the influence of nodes are set up. On this basis, a new comprehensive vulnerability assessment method of nodes is put forward by using super efficiency data envelopment analysis to scientific integration. Finally, the simulative results of IEEE30-bus system indicated that the proposed model is rational and valid.

    Full Text Available ObjectiveCognitive frailty (CF refers to the co-occurrence of physical frailty (PF and cognitive impairment in persons without dementia. We aimed to explore the prevalence and associated factors of CF in China.MethodData were obtained from the China Comprehensive Geriatric Assessment Study. A total of 5,708 community-dwelling older adults without dementia were included. CF was assessed using the Mini–Mental State Examination for the evaluation of cognitive status and the Comprehensive Geriatric Assessment-Frailty Index for the evaluation of PF. Participants with both cognitive impairment and PF were classified as having CF. Sociodemographic and clinical history was also collected. Logistic analysis was used to explore the association between the associated factors and CF.ResultsThe overall crude prevalence of CF was 3.3% [95% confidence interval (CI = 3.0–4.0], and the standard prevalence of CF was 2.7% (95% CI = 2.0–3.0. The prevalence of CF was significantly higher in women than men and higher in residents of rural areas than urban areas. Moreover, the prevalence of CF was found to increase with age. Multiple factor analysis showed that depression (OR = 2.462, 95% CI = 1.066–5.687 and hearing impairment (OR = 2.713, 95% CI = 1.114–6.608 were independent associated factors of CF in elderly individuals with PF.ConclusionOur results provide the first empirical evidence of CF in China. We have identified several associated factors with CF which should be considered while assessing older adults. More studies in Chinese population with CF are demanded to confirm with our findings.

    Full Text Available Purpose: Xerostomia is a well known complication of radiation for head and neck cancer. It causes significant impairment of Quality Of Life (QOL.Comprehensive assessment is possible with the help of scintigraphy, Dose-volume histogram (DVH parameters as well as QOL questionnaire.Methods: Thirty patients of head and neck cancer undergoing radiation were assessed for xerostomia. Scintigraphic assessment of parotid gland function was done before and at six weeks after radiation. QOL questionnaire was administered before, during, and at six weeks after radiation as well as at two years of follow up. Dose received by parotids were correlated with scintigraphic and QOL outcomes.Results: Mean parotid gland volume and dose received were 24.9 cc and 45.3 Gy respectively. Mean Salivary Excretion Factor (SEF decreased from 54.1 to 12 at six weeks after radiation. QOL scores worsened from first week (mean value: 2.37 of radiotherapy (RT to fourth week (mean value: 15.50, p < 0.0000 , remained same till completion of RT (mean value: 17.57, p = 0.1063 and at six weeks after radiation (mean value:16.10, p = 0.2519 . There was a significant decrease in QOL scores between post RT six weeks versus two years follow up (p < 0.0000. Mean parotid dose and QOL scores correlated at six weeks (p < 0.0000, whereas no correlation was found between SEF and QOL.Conclusion: Comprehensive assessment of parotid gland function with Scintigraphy, QOL questionnaire and its correlation with dose volume parameters is helpful in quantifying xerostomia. Even though radiation induced xerostomia persisted for a long time after radiation, it did not translate to decreased QOL.

  17. Assessing Viability and Sustainability: a Systems-based Approach for Deriving Comprehensive Indicator Sets

    Directory of Open Access Journals (Sweden)

    Hartmut Bossel

    2002-01-01

    Full Text Available Performance assessment in holistic approaches such as integrated natural resource management has to deal with a complex set of interacting and self-organizing natural and human systems and agents, all pursuing their own "interests" while also contributing to the development of the total system. Performance indicators must therefore reflect the viability of essential component systems as well as their contributions to the viability and performance of other component systems and the total system under study. A systems-based derivation of a comprehensive set of performance indicators first requires the identification of essential component systems, their mutual (often hierarchical or reciprocal relationships, and their contributions to the performance of other component systems and the total system. The second step consists of identifying the indicators that represent the viability states of the component systems and the contributions of these component systems to the performance of the total system. The search for performance indicators is guided by the realization that essential interests (orientations or orientors of systems and actors are shaped by both their characteristic functions and the fundamental and general properties of their system environments (e.g., normal environmental state, scarcity of resources, variety, variability, change, other coexisting systems. To be viable, a system must devote an essential minimum amount of attention to satisfying the "basic orientors" that respond to the properties of its environment. This fact can be used to define comprehensive and system-specific sets of performance indicators that reflect all important concerns. Often, qualitative indicators and the study of qualitative systems are sufficient for reliable performance assessments. However, this approach can also be formalized for quantitative computer-assisted assessment. Examples are presented of indicator sets for the sustainable development of

    Improved methods for assessing bulbar impairment are necessary for expediting diagnosis of bulbar dysfunction in ALS, for predicting disease progression across speech subsystems, and for addressing the critical need for sensitive outcome measures for ongoing experimental treatment trials. To address this need, we are obtaining longitudinal profiles of bulbar impairment in 100 individuals based on a comprehensive instrumentation-based assessment that yield objective measures. Using instrumental approaches to quantify speech-related behaviors is very important in a field that has primarily relied on subjective, auditory-perceptual forms of speech assessment(1). Our assessment protocol measures performance across all of the speech subsystems, which include respiratory, phonatory (laryngeal), resonatory (velopharyngeal), and articulatory. The articulatory subsystem is divided into the facial components (jaw and lip), and the tongue. Prior research has suggested that each speech subsystem responds differently to neurological diseases such as ALS. The current protocol is designed to test the performance of each speech subsystem as independently from other subsystems as possible. The speech subsystems are evaluated in the context of more global changes to speech performance. These speech system level variables include speaking rate and intelligibility of speech. The protocol requires specialized instrumentation, and commercial and custom software. The respiratory, phonatory, and resonatory subsystems are evaluated using pressure-flow (aerodynamic) and acoustic methods. The articulatory subsystem is assessed using 3D motion tracking techniques. The objective measures that are used to quantify bulbar impairment have been well established in the speech literature and show sensitivity to changes in bulbar function with disease progression. The result of the assessment is a comprehensive, across-subsystem performance profile for each participant. The profile, when compared to

    The assessment of clinical competence in health disciplines is a critical issue. Universities have a responsibility to graduate students who can demonstrate fitness to practice because clinical competence relates directly to the quality of patients' care-the quality of their treatment, their health outcomes, and their experience. In respect of the last of these, this article argues that the nature of what we term "clinical competence" ought to recognize the patient before the medical/dental condition or clinical intervention and, in order to achieve this, dental education should adopt learning, teaching, and assessment strategies that develop integrated learning outcomes consistent with a paradigm of comprehensive care. The article describes the ways in which this paradigm has been operationalized in the learning, teaching, and assessment strategies at Griffith University in Australia. It places a particular focus upon the assessment methods used in the Bachelor of Oral Health program. In this way, the article aims to illustrate ways that the quality of the assessment of clinical competence can, and should, be improved. While this is a work in progress, this description may be useful for educators at other academic dental institutions who wish to adopt, adapt, and develop similar approaches.

    2008-01-01

    Pragmatic language impairment in children with specific language impairment has proved difficult to assess, and the nature of their abilities to comprehend pragmatic meaning has not been fully investigated. To develop both a cognitive approach to pragmatic language assessment based on Relevance Theory and an assessment tool for identifying a group of children with pragmatic language impairment from within an specific language impairment group. The authors focused on Relevance Theory's view of the role of context in pragmatic language comprehension using questions of increasing pragmatic complexity in different verbal contexts (scenarios with and without pictures and a story with supporting pictures). The performances of the children with and without pragmatic impairment on the most pragmatically demanding Implicature questions were examined. This study included 99 children: 27 with specific language impairment (including nine pragmatically impaired children) and two groups of typically developing children (32 children aged 5-6 years and 40 children aged 7-11 years). The specific language impairment group performed similarly to their peers when utilizing context in inferring referents, inferring semantic meaning, and generating Implicatures, only when the answer was provided by pictorial context. Both the children with specific language impairment and the 5-6 year olds were not yet competent at utilizing verbal context when answering the most pragmatically demanding questions (targeting Implicature). On these questions the children with pragmatic language impairment performed significantly poorer than the rest of the specific language impairment group and performance scores on Implicature questions were found to identify accurately the children with pragmatic language impairment from the rest of the specific language impairment group (sensitivity = 89%). Children's ability to infer and integrate information in the comprehension of pragmatic meaning was found to be

    We study a one-dimensional extended Hubbard model with longer-range Coulomb interactions at quarter-filling in the strong coupling limit. In this limit, we find the one dimensional transverse field Ising model (TFIM) to be the effective Hamiltonian governing the dynamics of the charge degrees of freedom. We find two different charge-ordered (CO) ground states as the strength of the longer range interactions is varied. At lower energies, these CO states drive two different spin-ordered ground states. A variety of response functions computed here bear a remarkable resemblance to recent experimental observations for organic TMTSF systems, and so we propose that these systems are proximate to a QCP associated with T = 0 charge order.

    In the interests of guarding lives and property against the effects of earthquakes, building codes are frequently enforced when erecting conventional structures, usually calling for simple, static calculations. Where more vulnerable facilities are involved, the failure of which, or of parts of which, could subject the environment to harmful substances, more sophisticated methods are used to compute or verify their design, often accompanied by safety margins intended to compensate for uncertainties encountered at various stages of the analysis that begins with input seismic data and culminates with an effective anti-seismic design. The forthcoming discussion will deal with what is known of the characteristics of strong ground motion, highly variable according to context, without entering into the problems raised by seismotectonic studies, which actually constitute the first aspect that must be addressed when performing such an analysis. Our conclusion will be devoted to cogent R and D work in this area

    2002-02-01

    The U.S. Department of Energy's Columbia River Comprehensive Impact Assessment (CRCIA) was an ambitious attempt to direct its cleanup of the Hanford Nuclear Reservation toward the most significant risks to the Columbia River resulting from past plutonium production. DOE's approach was uncommonly open, including tribal, regulatory agency, and other Hanford interest group representatives on the board that was to develop the assessment approach. The CRCIA process had attributes of the "analytic-deliberative" process for risk assessment recommended by the National Research Council. Nevertheless, differences between the DOE and other participants over what was meant by the term "comprehensive" in the group's charge, coupled with differing perceptions of the likely effectiveness of remediation efforts in reducing risks, were never resolved. The CRCIA effort became increasingly fragmented and the role its products were to play in influencing future clean-up decisions increasingly ambiguous. A procedural evaluation of the CRCIA process, based on Thomas Webler's procedural normative model of public participation, reveals numerous instances in which theoretical-normative discourse disconnects occurred. These had negative implications for both the basic procedural dimensions of Webler's model-fairness and competence. Tribal and other interest group representatives lacked the technical resources necessary to make or challenge what philosopher Jurgens Habermas terms cognitive validity claims, while DOE and its contractors did not challenge normative claims made by tribal representatives. The results are cautionary for implementation of the analytic-deliberative process. They highlight the importance of bringing rigor to the evaluation of the quality of the deliberation component of risk characterization via the analytic-deliberative process, as well as to the analytic component.

    In confined swine buildings, temperature, humidity, and air quality are all important for animal health and productivity. However, the current swine building environmental control is only based on temperature; and evaluation and control methods based on multiple environmental factors are needed. In this paper, fuzzy comprehensive evaluation (FCE) theory was adopted for multi-factor assessment of environmental quality in two commercial swine buildings using real measurement data. An assessment index system and membership functions were established; and predetermined weights were given using analytic hierarchy process (AHP) combined with knowledge of experts. The results show that multi-factors such as temperature, humidity, and concentrations of ammonia (NH 3 ), carbon dioxide (CO 2 ), and hydrogen sulfide (H 2 S) can be successfully integrated in FCE for swine building environment assessment. The FCE method has a high correlation coefficient of 0.737 compared with the method of single-factor evaluation (SFE). The FCE method can significantly increase the sensitivity and perform an effective and integrative assessment.

    Tamoxifen bioactivation to endoxifen is mediated primarily by CYP2D6; however, considerable variability remains unexplained. Our aim was to perform a comprehensive assessment of the effect of genetic variation in tamoxifen-relevant enzymes and transporters on steady-state endoxifen concentrations. Comprehensive genotyping of CYP enzymes and transporters was performed using the iPLEX ADME PGx Pro Panel in 302 tamoxifen-treated breast cancer patients. Predicted activity phenotype for 19 enzymes and transporters were analyzed for univariate association with endoxifen concentration, and then adjusted for CYP2D6 and clinical covariates. In univariate analysis, higher activity of CYP2C8 (regression β=0.22, P=0.020) and CYP2C9 (β=0.20, P=0.04), lower body weight (β=-0.014, P<0.0001), and endoxifen measurement during winter (each β<-0.39, P=0.002) were associated with higher endoxifen concentrations. After adjustment for the CYP2D6 diplotype, weight, and season, CYP2C9 remained significantly associated with higher concentrations (P=0.02), but only increased the overall model R by 1.3%. Our results further support a minor contribution of CYP2C9 genetic variability toward steady-state endoxifen concentrations. Integration of clinician and genetic variables into individualized tamoxifen dosing algorithms would marginally improve their accuracy and potentially enhance tamoxifen treatment outcomes.

    Potocki-Shaffer syndrome is a rare contiguous gene deletion syndrome due to haploinsufficiency of the 11p11.2p12 region and is characterized by craniofacial abnormalities, developmental delay, intellectual disability, multiple exostoses, and biparietal foramina. In this study, six patients with the Potocki-Shaffer syndrome were identified and evaluated using a multidisciplinary protocol that included assessments by a geneticist, ophthalmologist, otolaryngologist, orthopedist, nephrologist, audiologist, and neuropsychologist. Diagnostic studies included skeletal survey, magnetic resonance imaging of the brain, renal ultrasound, complete blood count, comprehensive metabolic panel, thyroid studies, and urinalysis. Using array comparative genomic hybridization, we further characterized the deletion in five of these patients. The results of these evaluations were combined with a comprehensive review of reported cases. Our data highlight the characteristic facial features, biparietal foramina, moderate-to-severe developmental delay and intellectual disability, myopia and strabismus, and multiple exostoses seen with this disorder. We also identify for the first time an association of Potocki-Shaffer syndrome with sensorineural hearing loss and autistic behaviors. Finally, we provide recommendations for the health maintenance of patients with Potocki-Shaffer syndrome. (c) 2010 Wiley-Liss, Inc.

    Shakya, Pramila

    The purpose of this study was to determine if the use of active-learning activities to teach weak force and strong force to students enrolled in various courses at The University of Southern Mississippi, Hattiesburg campus and Gulf Park campus at different class times would increase their knowledge. There were eighty-six students that took part in this study. The study was conducted in the lab classes of an introductory astronomy survey course (AST 111), an introductory algebra-based physics course (PHY 112), and an introductory calculus-based physics course (PHY 202) during fall semester, 2014. Each class was randomly assigned as active-learning or direct instruction. A pretest followed by lecture was administered to all groups. The active-learning group performed four activities whereas the direct group watched a video irrelevant to the lesson. At the end of the lesson, the same post-test was given to all groups. Various statistical methods were used to analyze the differences in mean pretest and posttest scores. Overall, results show that the mean posttest scores were higher than the mean pretest scores. Findings support the use of active-learning activities work to the small number of students or the equal number of students in a group. The mean posttest scores of the direct instruction classes were higher than those of the active-learning groups.

    Older adults comprise a heterogeneous population group that usually has a high disease burden, comorbidities, and, in many cases, subclinical conditions that compromise their health and quality of life. In addition to the physical component, the health conditions of elderly individuals are significantly influenced by cognitive and affective components, social and family factors such as abandonment, and functional factors including the ability to perform everyday activities. In response to this complex scenario, the comprehensive geriatric evaluation constitutes a multidimensional and interdisciplinary diagnostic tool that assesses the health of older adults in all of its complexity by considering the physical, mental, social/family, and functional needs to obtain full knowledge of older person's health status and creating a plan that consists of appropriate and individualized interventions that considers the preferences and values of older individuals and their families.

  9. Psychometric validation of the Sentence Verification Technique to assess L2 reading comprehension ability

    Full Text Available English teachers use the Sentence Verification Technique (Royer et al., 1979 to determine the readability of written material for their classes. This process requires students to read short passages from a book, followed by isolated sentences. These sentences can be either identical or different from the original passages, in their meaning as well as in their form. For each sentence, students must indicate whether or not itscontent corresponds to that of the original passage. This paper reports on the design and assessment of an SVT test created for measuring reading comprehension ability, based on four English texts. The instrument was administered to 171 adult English learners, of various levels of English proficiency. The data were analysed using both traditional psychometric methods and the Raschmodel. Results indicate that the test shows high internal consistency, that it respects the basic assumptions behind the Rasch model, and that it is in the recommended range of difficulty for that technique.

  10. Towards a comprehensive assessment and framework for low and high flow water risks

    2017-04-01

    Driven by international organizations such as the Intergovernmental Panel on Climate Change (IPCC) the past years have seen a move from a vulnerability concept of climate change impacts towards a risk framework. Risk is now conceived at the intersection of climate-driven hazard and socioeconomic-driven vulnerability and exposure. The concept of risk so far has been mainly adopted for sudden-onset events. However, for slow-onset and cumulative climate change impacts such as changing water resources there is missing clarity and experience how to apply a risk framework. Research has hardly dealt with the challenge of how to integrate both low and high flow risks in a common framework. Comprehensive analyses of risks related to water resources considering climate change within multi-dimensional drivers across different scales are complex and often missing in climate-sensitive mountain regions where data scarcity and inconsistencies represent important limitations. Here we review existing vulnerability and risk assessments of low and high flow water conditions and identify critical conceptual and practical gaps. Based on this, we develop an integrated framework for low and high flow water risks which is applicable to both past and future conditions. The framework explicitly considers a water balance model simulating both water supply and demand on a daily basis. We test and apply this new framework in the highly glacierized Santa River catchment (SRC, Cordillera Blanca, Peru), representative for many developing mountain regions with both low and high flow water risks and poor data availability. In fact, in the SRC, both low and high flow hazards, such as droughts and floods, play a central role especially for agricultural, hydropower, domestic and mining use. During the dry season (austral winter) people are increasingly affected by water scarcity due to shrinking glaciers supplying melt water. On the other hand during the wet season (austral summer) high flow water

  11. Comprehensive, Quantitative Risk Assessment of CO{sub 2} Geologic Sequestration

    Lepinski, James

    2013-09-30

    A Quantitative Failure Modes and Effects Analysis (QFMEA) was developed to conduct comprehensive, quantitative risk assessments on CO{sub 2} capture, transportation, and sequestration or use in deep saline aquifers, enhanced oil recovery operations, or enhanced coal bed methane operations. The model identifies and characterizes potential risks; identifies the likely failure modes, causes, effects and methods of detection; lists possible risk prevention and risk mitigation steps; estimates potential damage recovery costs, mitigation costs and costs savings resulting from mitigation; and ranks (prioritizes) risks according to the probability of failure, the severity of failure, the difficulty of early failure detection and the potential for fatalities. The QFMEA model generates the necessary information needed for effective project risk management. Diverse project information can be integrated into a concise, common format that allows comprehensive, quantitative analysis, by a cross-functional team of experts, to determine: What can possibly go wrong? How much will damage recovery cost? How can it be prevented or mitigated? What is the cost savings or benefit of prevention or mitigation? Which risks should be given highest priority for resolution? The QFMEA model can be tailored to specific projects and is applicable to new projects as well as mature projects. The model can be revised and updated as new information comes available. It accepts input from multiple sources, such as literature searches, site characterization, field data, computer simulations, analogues, process influence diagrams, probability density functions, financial analysis models, cost factors, and heuristic best practices manuals, and converts the information into a standardized format in an Excel spreadsheet. Process influence diagrams, geologic models, financial models, cost factors and an insurance schedule were developed to support the QFMEA model. Comprehensive, quantitative risk assessments

  12. Alternative Assessment Strategy and Its Impact on Student Comprehension in an Undergraduate Microbiology Course

    2009-12-01

    Full Text Available Medical Microbiology is a content-intensive course that requires a large time commitment from the students. Students are typically biology or prenursing majors, including students headed for professional schools, such as medical school and pharmacy school. This group is somewhat diverse in terms of background science coursework, so it can be difficult to teach in a way that benefits all the students. Numerous changes have been implemented in our microbiology curriculum to address the different abilities of our students by altering assessment and teaching strategies. It was hypothesized that changing the assessment strategy from the traditional scheme of two or three exams and one final to a new model of seven or eight shorter exams would have a positive impact on student comprehension and retention. The quantity of material taught or expected of the students to learn did not change, but there was definitely an impact on them. Although 30.0% of students routinely did not pass microbiology in previous semesters, the new method of assessment resulted in only 9.63% not completing the semester successfully, as determined by earning a grade of C or better. There is some evidence from conversations and interviews with students that indicates a positive impact of this methodology on student attitude. Implementation of these changes in other courses and their current effectiveness will be examined in the future, with an eye towards more broadly applicable successful teaching techniques in the sciences, especially for nonmajors.

  13. Assessment of potential strong ground motions in the city of Rome

    1994-06-01

    Full Text Available A methodology is used which combines stochastic generation of random series with a finite-difference technique to estimate the expected horizontal ground motion for the city of Rome as induced by a large earthquake in the Central Apennines. In this approach, source properties and long-path propagation are modelled through observed spectra of ground motion in the region, while the effects of the near-surface geology in the city are simulated by means of a finite-difference technique applied to 2-D models including elastic and anelastic properties of geologic materials and topographic variations. The parameters commonly used for earthquake engineering purposes are estimated from the simulated time histories of horizontal ground motion. We focus our attention on peak ground acceleration and velocity, and on the integral of the squared acceleration and velocity (that are proportional to the Arias intensity and seismic energy flux, respectively. Response spectra are analyzed as well. Parameter variations along 2-D profiles visualize the effects of the small-scale geological heterogeneities and topography irregularities on ground motion in the case of a strong earthquake. Interestingly, the largest amplification of peak ground acceleration and Arias intensity does not necessarily occur at the same sites where peak ground velocity and flux of seismic energy reach their highest values, depending on the frequency band of amplification. A magnitude 7 earthquake at a distance of 100 km results in peak ground accelerations ranging from 30 to 70 gals while peak ground velocities are estimated to vary from 5 to 7 cm/s; moreover, simulated time histories of horizontal ground motion yield amplitudes of 5% damped pseudovelocity response spectra as large as 15-20 cm/s for frequencies from 1to 3 Hz. In this frequency band, the mean value is 7 cm/s for firm sites and ranges from 10 to 13 cm/s for soil sites. All these results are in good agreement with predictions

    We have recently developed and validated a screening test for comprehensive geriatric assessment (CGA). We investigated the prevalence of geriatric problems in elderly inpatients using CGA, and determined the relationship between geriatric problems and cognitive decline. We enrolled consecutive elderly inpatients aged >65 years who were admitted to all of the hospital departments at Tokyo Medical University Hospital, Tokyo, Japan, between July and December 2013. We investigated the prevalence of specific geriatric problems or situations in elderly inpatients using a screening test for CGA named "Dr. SUPERMAN." We examined 3969 elderly inpatients (2211 men and 1758 women; mean age 75.5 ± 6.7 years) using CGA. Inpatients were divided into three groups by age, namely, 65-74 years, 75-84 years and ≥85 years. Inpatients were divided into the two groups of "internal medicine" and "other departments." Geriatric problems were more frequently found in patients who were aged ≥85 years and admitted to "internal medicine" departments. Furthermore, multiple regression analysis found cognitive decline significantly correlated with ADL decline, age, poor medication adherence, upper and lower extremity function disorder, visual/auditory disorder, and urinary disorder. In particular, cognitive decline strongly correlated with a decline in activities of daily living. CGA should be considered for the treatment of elderly inpatients, particularly those with cognitive decline and admitted to "internal medicine" departments.

    The probabilistic seismic performance of a standard Korean nuclear power plant (NPP) with an idealized isolation is investigated in the present work. A probabilistic seismic hazard analysis (PSHA) of the Wolsong site on the Korean peninsula is performed by considering peak ground acceleration (PGA) as an earthquake intensity measure. A procedure is reported on the categorization and selection of two sets of ground motions of the Tohoku earthquake, i.e. long-period and common as Set A and Set B respectively, for the nonlinear time history response analysis of the base-isolated NPP. Limit state values as multiples of the displacement responses of the NPP base isolation are considered for the fragility estimation. The seismic risk of the NPP is further assessed by incorporation of the rate of frequency exceedance and conditional failure probability curves. Furthermore, this framework attempts to show the unacceptable performance of the isolated NPP in terms of the probabilistic distribution and annual probability of limit states. The comparative results for long and common ground motions are discussed to contribute to the future safety of nuclear facilities against drastic events like Tohoku.

    The establishment of baseline IUCN Red List assessments for plants is a crucial step in conservation planning. Nowhere is this more important than in biodiversity hotspots that are subject to significant anthropogenic pressures, such as Madagascar. Here, all Madagascar palm species are assessed using the IUCN Red List categories and criteria, version 3.1. Our results indicate that 83% of the 192 endemic species are threatened, nearly four times the proportion estimated for plants globally and exceeding estimates for all other comprehensively evaluated plant groups in Madagascar. Compared with a previous assessment in 1995, the number of Endangered and Critically Endangered species has substantially increased, due to the discovery of 28 new species since 1995, most of which are highly threatened. The conservation status of most species included in both the 1995 and the current assessments has not changed. Where change occurred, more species have moved to lower threat categories than to higher categories, because of improved knowledge of species and their distributions, rather than a decrease in extinction risk. However, some cases of genuine deterioration in conservation status were also identified. Palms in Madagascar are primarily threatened by habitat loss due to agriculture and biological resource use through direct exploitation or collateral damage. The recent extension of Madagascar's protected area network is highly beneficial for palms, substantially increasing the number of threatened species populations included within reserves. Notably, three of the eight most important protected areas for palms are newly designated. However, 28 threatened and data deficient species are not protected by the expanded network, including some Critically Endangered species. Moreover, many species occurring in protected areas are still threatened, indicating that threatening processes persist even in reserves.

    Full Text Available This article presents a test for assessing metaphor comprehension (MCT in explicit linguistic form for subjects aged 9- to 14 years-old, i.e. in a transitional age where significant qualitative changes appear for this type of ability. Metaphor is viewed as a form of semantic conflict induced by the anomalous combination of the conventional meanings of its main constituents - tenor and vehicle - and metaphor comprehension is framed as a metasemantic ability based on the analysis of these meanings (Gombert 1990, that can have implications both for teaching and for learning strategies.The authors propose a functionalist piagetian frame, based on Piaget’s latest equilibration model (1975, for analysing how this semantic conflict can be faced and solved by children in the developmental span considered. The test is paper-and-pencil, composed of 12 items subdivided into 2 groups of metaphors: Psycho-physical (PP and Conceptual (C, mainly drawn and adapted to Italian language from international literature on metaphor comprehension. The sample is composed of 874 Italian children from 4th to 8th grade, with gender balance, of average social background. By means of Principal Components Analysis, with oblimin rotation, a two-factor solution emerged, that espouses the C/PP metaphors distinction. All corrected item-total correlation coefficients >.30 were representative and acceptable. Correlation coefficients between MCT and Standard progressive Matrices (SPM38 and some validated metalinguistic subtests were all significant at p <0.01 level, showing good convergent validity. Cronbach’s Alpha coefficients for the two subscales were: .62 (C, .51 (PP and .70 for MCT total score. Test-retest correlation oefficients for the two subscales were .79 (C, .69 (PP, and .83 for MCT total score.

    Full Text Available In the context of economic sanctions and growing international isolation, the research into regional differences in integration development acquires special relevance for Russia; this fact determines the need for a comprehensive assessment of integration activity of business structures in Russian regions. The diversity of approaches to the study of problems and prospects of economic integration and the current debate about the role of integration processes in the development of regional economies determined a comprehensive approach to the concepts of “integration” and “integration activity” in order to create objective prerequisites for analyzing integration activity of business structures in the regions of Russia. The information base of the research is the data of Russian information and analytical agencies. The tools used in the research include methods for analyzing structural changes, methods for analyzing economic differentiation and concentration, nonparametric statistics methods, and econometric analysis methods. The first part of the paper shows that socio-economic development in constituent entities of Russia is closely connected with the operation of integrated business structures located on their territory. Having studied the structure and dynamics of integration activity, we reveal the growing heterogeneity of integration activity of business structures in Russian regions. The hypothesis about significant divergence of mergers and acquisitions for corporate structures in Russian regions was confirmed by high values of the Gini coefficient, the Herfindahl index and the decile differentiation coefficient. The second part of the paper contains a comparative analysis and proposes an econometric approach to the measurement of integration activity of business structures in subjects of the Russian Federation on the basis of integral synthetic categories. The approach we propose focuses on the development of a system of indicators

    The training of medical specialists is a long and complex process. Its purpose is to guarantee the society that they are the right professionals to meet the health needs of the population. The first step to ensure this objective is the admission process. In psychiatry this process, monitoring resident students and the criteria for each one are different in each country. Admission in Colombia is a heterogeneous process, not standardized, which varies greatly from one university to another, even between private and public universities. At the National University of Colombia, the admissions process is handled by the Admissions Office and includes: a written test for which you must obtain a minimum score, a resume rating and an interview. The Teaching Committee and the Department of Psychiatry considered the admission procedure in general to be good, but in need of refinement. Due to the experience of some teachers and given the current rules, a "comprehensive assessment" for master and doctoral students was required and in 1996 it was decided that this method of assessment for admission to a specialization in Psychiatry would serve to complement the admission process. The article describes the experience of the process and its outcomes, strengths and weaknesses. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    2007-12-01

    The Comprehensive Assessment of Prospective Memory (CAPM) is a questionnaire designed to evaluate frequency of prospective memory (PM) failures in people with brain injury. The aims of this study were to investigate the psychometric properties of the CAPM, including test-retest reliability and internal consistency, and to establish normative data by comparing CAPM scores between groups on the basis of sex, age, and education. Data were collected on 95 people aged 15-60 years living in the community, with no history of brain injury, using the CAPM. The results showed that the test-retest reliability and internal consistency for the CAPM were within acceptable ranges, indicating that the CAPM provides a stable and homogenous measure of an individual's self-report of PM failures. Normative data are presented in two age groups based on the significant difference found between the age groups 15-30 years and 31-60 years. These established norms can be used to describe perceived or observed behaviours indicative of PM failure in patients with brain injury by comparing CAPM ratings from significant others with the norms. The CAPM questionnaire provides researchers or clinicians with a stable and reliable assessment option that specifically focuses on PM for individuals with brain injury.

    Full Text Available Abstract Background The Comprehensive Geriatric Assessment (CGA is an analytical tool increasingly implemented in clinical practice. Breast cancer is primarily a disease of older people; however, most evidence-based research is aimed at younger patients. Methods A systematic review of literature was carried out to assess the use of CGA in older breast cancer patients for clinical decision making. The PubMed, Embase and Cochrane databases were searched. Results A total of nine useful full text article results were found. Only five of these were exclusively concerned with early breast cancer; thus, studies involving a variety of cancer types, stages and treatments were accepted, as long as they included early breast cancer.The results comprised a series of low sources of evidence. However, all results shared a common theme: the CGA has a use in determining patient suitability for different types of cancer treatment and subsequently maximizing the patient’s quality of life. Conclusions There is not yet sufficient high level evidence to instate CGA guidelines as a mandatory practice in the management of breast cancer, due to the heterogeneity of available studies. More studies need to be conducted to cement current work on the benefits of the CGA. An area of particular interest is with regard to treatment options, especially surgery and chemotherapy, and identifying patients who may be suitable for these treatments.

However, all results shared a common theme: the CGA has a use in determining patient suitability for different types of cancer treatment and subsequently maximizing the patient's quality of life. There is not yet sufficient high level evidence to instate CGA guidelines as a mandatory practice in the management of breast cancer, due to the heterogeneity of available studies. More studies need to be conducted to cement current work on the benefits of the CGA. An area of particular interest is with regard to treatment options, especially surgery and chemotherapy, and identifying patients who may be suitable for these treatments.

    Full Text Available As the significant variation of GM in waves for very large container ships, strict demands are raised for this ship type in the evaluation and safety assessment of parametric roll. Targeting a 10 000 TEU container ship sailing in head sea, this study conducts a series of calculations and evaluations on parametric roll motion in which each loading condition is calculated step-by-step. Direct calculation is conducted if neither Level 1 nor Level 2 is satisfied. In this paper, an independently developed time-domain simulation is conducted for loading conditions that fail to match the Level 2 criteria, which is based on a typical 3-DOF weakly nonlinear numerical model. Ship velocity and wave conditions are taken into consideration to explore sensible conditions concerning parametric roll. Finally, according to the results, corresponding safety assessments and several avoidance measures are proposed, such as reducing the height of the center of gravity and raising the speed moderately. In addition, if wave predictions can be detected in advance, the circumstance of the natural rolling period being twice as great as the encountering period should be avoided, which is the most sensible factor for inducing parametric roll. Comprehensive calculation and checking for the 10 000 TEU ship can instruct the general design and improve safety for very large container ships; as a result, remarkable engineering applications and reference value can be recognized.

    Full Text Available Desertification is a typical disaster risk event in which human settlements and living environments are destroyed. Desertification Disaster Risk Assessment can control and prevent the occurrence and development of desertification disasters and reduce their adverse influence on human society. This study presents the methodology and procedure for risk assessment and zoning of desertification disasters in Horqin Sand Land. Based on natural disaster risk theory and the desertification disaster formation mechanism, the Desertification Disaster Risk Index (DDRI combined hazard, exposure, vulnerability and restorability factors and was developed mainly by using multi-source data and the fuzzy comprehensive evaluation method. The results showed that high risk and middle risk areas account for 28% and 23% of the study area, respectively. They are distributed with an “S” type in the study area. Low risk and very low risk areas account for 21% and 10% of the study area, respectively. They are distributed in the west-central and southwestern parts. Very high risk areas account for 18% of the study area and are distributed in the northeastern parts. The results can be used to know the desertification disaster risk level. It has important theoretical and practical significance to prevention and control of desertification in Horqin Sand Land and even in Northern China.

    This study examined correlates of preschoolers' anxiety disorders using a comprehensive, multimethod design. Participants included a community sample of 541 three-year-old children, of whom 106 (19.6%) met criteria for at least 1 anxiety disorder. Child and parental psychopathology and life stress were assessed with clinical interviews. Child temperament and parenting behavior were assessed with laboratory observations. Mothers and fathers reported on their parenting styles. Compared to preschoolers with no anxiety disorder, preschoolers with an anxiety disorder were more likely to meet criteria for comorbid depressive and oppositional defiant disorders and to exhibit greater temperamental behavioral inhibition and lower positive affectivity, and more sleep problems. Children with anxiety disorders also experienced more stressful life events in the previous 6 months, and their mothers had a higher rate of current anxiety disorders. Compared to children with other anxiety disorders, children with only specific phobia exhibited a somewhat different pattern of associations than children with other anxiety disorders. Overall, the findings suggest that many of the correlates observed in older youth with anxiety disorders are also observed in preschoolers.

    A catalog has been prepared which contains information for: (1) world-wide, ground-motion accelerograms (2) the accelerograph sites where these records were obtained, and (3) the seismological parameters of the causative earthquakes. The catalog is limited to data for those accelerograms which have been digitized and published. In addition, the quality and completeness of these data are assessed. This catalog is unique because it is the only publication which contains comprehensive information on the recording conditions of all known digitized accelerograms. However, information for many accelerograms is missing. Although some literature may have been overlooked, most of the missing data has not been published. Nevertheless, the catalog provides a convenient reference and useful tool for earthquake engineering research and applications. (author)

    This study aimed to examine the confluence of depression, cognitive impairment, and vascular risk factors in older individuals. The study uses baseline data from the National Alzheimer's Coordinating Center. Data were collected across Alzheimer's Disease Centers in the USA. The sample included 12,634 individuals (cognitive intact = 8022; amnestic mild cognitive impairment [aMCI] = 3652; nonamnestic MCI [nonaMCI] = 960). The Geriatric Depression Scale assessed depression; the Trail Making Test assessed executive function. The proportion of participants with depression was higher in the aMCI (18%) and nonaMCI group (21%) as compared with that in the cognitively intact group (8%); there was no difference in rates of depression between aMCI and nonaMCI groups. The proportion of participants with executive dysfunction differed between nondepressed and depressed individuals for the cognitively intact (8% vs. 12%) and aMCI groups (28% vs. 35%), but not for the nonaMCI group (37% vs. 41%). Nine percent of the cognitively intact group had executive dysfunction compared with 31% of the aMCI group and 40% of the nonaMCI group. The proportion of participants with hypertension was greater in individuals with executive dysfunction compared with those with no executive deficits; the presence of hypertension was not associated with depression severity. The confluence of vascular risk factors, episodic memory impairment, and depression and executive dysfunction highlights the need for comprehensive assessment of depressed older adults that can aid clinicians in the formulation of treatment planning and inform clinicians and researchers about long-term prognosis.

    The Joint Commission on the Accreditation of Healthcare Organizations requires that hospitals have a planned approach to systematically collect data on processes related to the use, ordering, and administering of blood components. This study describes how a comprehensive blood-administering assessment program and the FOCUS-PDCA approach improved overall blood-administering practices. Nurses were trained to observe blood issuance, blood administering, and patient monitoring steps, and to audit patient's charts to measure compliance with blood-ordering procedures. The observations were recorded on a standardized scannable form, which allowed automatic entry of recorded data directly into a computer database. A total of 982 assessments were completed during the 51-month study period. Documentation of informed consent improved from 80 percent to 100 percent. Compliance with a California law that requires patients to receive information on the risks, benefits, and alternatives to transfusion rose from 30 percent to 100 percent. Physicians' compliance in specifying the rate of blood administration improved from 30 percent to 100 percent, and verification of information on the patient's identification band with the patient's self-identification rose from 50 percent to 100 percent. For all other blood-administering steps, compliance remained high throughout the study period. For the past 9 months, 100-percent compliance has been maintained for all transfusion processes, and during this period no mistransfusions or blood administration near-misses have been reported. The blood-administering assessment program described above has improved transfusion practice, reduced the number of near-miss events, and may have prevented mistransfusions.

  15. Conus: first comprehensive conservation red list assessment of a marine gastropod mollusc genus.

    Full Text Available Marine molluscs represent an estimated 23% of all extant marine taxa, but research into their conservation status has so far failed to reflect this importance, with minimal inclusion on the authoritative Red List of the International Union for the Conservation of Nature (IUCN. We assessed the status of all 632 valid species of the tropical marine gastropod mollusc, Conus (cone snails, using Red List standards and procedures to lay the groundwork for future decadal monitoring, one of the first fully comprehensive global assessments of a marine taxon. Three-quarters (75.6% of species were not currently considered at risk of extinction owing to their wide distribution and perceived abundance. However, 6.5% were considered threatened with extinction with a further 4.1% near threatened. Data deficiency prevented 13.8% of species from being categorised although they also possess characteristics that signal concern. Where hotspots of endemism occur, most notably in the Eastern Atlantic, 42.9% of the 98 species from that biogeographical region were classified as threatened or near threatened with extinction. All 14 species included in the highest categories of Critically Endangered and Endangered are endemic to either Cape Verde or Senegal, with each of the three Critically Endangered species restricted to single islands in Cape Verde. Threats to all these species are driven by habitat loss and anthropogenic disturbance, in particular from urban pollution, tourism and coastal development. Our findings show that levels of extinction risk to which cone snails are exposed are of a similar magnitude to those seen in many fully assessed terrestrial taxa. The widely held view that marine species are less at risk is not upheld.

The present study aimed to determine the effect of the comprehensive geriatric assessment (CGA on polypharmacy, potentially inappropriate medications (PIMs and potential prescribing omissions (PPOs, and to evaluate the economic reflections of medication changes.Methods: One thousand five hundred and seventy-nine older patients, who had undergone CGA, were retrospectively evaluated. The drugs, drug groups, and number of drugs that the patients used were recorded. Appropriate drug therapy was identified by both CGA and STOPP/START criteria. Based on these criteria, PIMs were discontinued and PPOs were started. The monthly cost of these drugs was calculated separately for PIMs and PPOs by using the drugstore records.Results: After CGA, while the prevalence of non-polypharmacy was increased from 43.3% to 65.6%, the prevalence of polypharmacy and hyperpolypharmacy was decreased from 56.7% to 34.4% and 12.0% to 3.6%, respectively. The three most common PIMs discontinued were proton pump inhibitors, anti-dementia drugs, and antipsychotics, respectively. However, the most common PPOs started were vitamin D and B12 supplements, and anti-depressants. After CGA, monthly saved total per capita cost of PIMs was US$12.8 and monthly increased total per capita cost of PPOs was $5.6.Conclusion: It was demonstrated that prevalence of polypharmacy, PIM, and PPO could be decreased by CGA including START/STOPP criteria in older adults. Furthermore, this will have beneficial effects on

    Geospatial literacy -- the ability to conceptualize, capture, analyze and communicate spatial phenomena -- represents an important competency for 21st Century learners in a period of 'Geospatial Revolution'. Though relevant to in-course learning, these skills are often taught externally, placing time and resource pressures on the service providers - commonly libraries - that are relied upon to provide instruction. The emergence of online and blended modes of instruction has presented a potential means of increasing the cost-effectiveness of such activities, by simultaneously reducing instructional costs, expanding the audience for these resources, and addressing student preferences for asynchronous learning and '24-7' access. During 2011 and 2012, McMaster University Library coordinated the development, implementation and assessment of blended learning modules for geospatial literacy instruction in first-year undergraduate Social Science courses. In this paper, we present the results of a comprehensive mixed-methods approach to assess the efficacy of implementing blended learning modules to replace traditional (face-to-face), library-led, first-year undergraduate geospatial literacy instruction. Focus groups, personal interviews and an online survey were used to assess modules across dimensions of: student use, satisfaction and accessibility requirements (via Universal Instructional Design [UID] principles); instructor and teaching staff perception of pedagogical efficacy and instructional effectiveness; and, administrator cost-benefit assessment of development and implementation. Results showed that both instructors and students identified significant value in using the online modules in a blended-learning setting. Reaffirming assumptions of students' '24/7' learning preferences, over 80% of students reported using the modules on a repeat basis. Students were more likely to use the modules to better understand course content than simply to increase their grade in

    Immune system dysregulation has been demonstrated to occur during spaceflight and has the potential to cause serious health risks to crewmembers participating in exploration class missions. As a part of an ongoing NASA flight experiment assessing viral immunity (DSO-500), a generalized immune assessment was performed on 3 crewmembers who participated in the recent STS-114 Space Shuttle mission. The following assays were performed: (1) comprehensive immunophenotype analysis; (2) T cell function/intracellular cytokine profiles; (4) secreted Th1/Th2 cytokine profiles via cytometric bead array. Immunophenotype analysis included a leukocyte differential, lymphocyte subsets, T cell subsets, cytotoxic/effector CD8+ T cells, memory/naive T cell subsets and constitutively activated T cells. Study timepoints were L-180, L-65, L-10, R+0, R+3 and R+14. Detailed data are presented in the poster text. As expected from a limited number of human subjects, data tended to vary with respect to most parameters. Specific post-flight alterations were as follows (subject number in parentheses): Granulocytosis (2/3), reduced NK cells (3/3), elevated CD4/CD8 ratio (3/3), general CD8+ phenotype shift to a less differentiated phenotype (3/3), elevated levels of memory CD4+ T cells (3/3), loss of L-selectin on T cell subsets (3/3), increased levels of activated T cells (2/3), reduced IL-2 producing T cell subsets (3/3), levels of IFNg producing T cells were unchanged. CD8+ T cell expression of the CD69 activation markers following whole blood stimulation with SEA+SEB were dramatically reduced postflight (3/3), whereas other T cell function assessments were largely unchanged. Cytometric bead array assessment of secreted T cell cytokines was performed, following whole blood stimulation with either CD3/CD28 antibodies or PMA+ionomycin for 48 hours. Specific cytokines assessed were IFNg, TNFa, IL-2, IL-4, IL-5, IL-10. Following CD3/CD28 stimulation, all three crewmembers had a mission

    Infidelity is a leading cause of relationship discord and dissolution, and couples generally report expectations to maintain monogamy. However, a majority of men and women report engaging in some form of infidelity at least once in their lives. Research assessing judgments of the behaviors that constitute infidelity is lacking. The three studies reported here advanced the literature by developing and validating the Definitions of Infidelity Questionnaire (DIQ), a comprehensive measure examining infidelity judgments. Exploratory and confirmatory factor analyses indicated four factors to the scale: sexual/explicit behaviors, technology/online behaviors, emotional/affectionate behaviors, and solitary behaviors. Investigation of the psychometric properties demonstrated the DIQ to be reliable and valid. Participants agreed that sexual/explicit behaviors comprised infidelity to the largest extent, whereas other types of behaviors (technology/online behaviors, emotional/affectionate behaviors, and solitary behaviors) were judged as comprising infidelity to a lesser extent. Men reported more permissive judgments than did women. This study provides insights regarding operationalizing infidelity and identifying areas of ambiguity and consensus. Implications of the findings for educators and practitioners working with individuals in intimate relationships are discussed.

    The environmental issues caused by the municipal solid waste disposal are becoming a worldwide concern. We studied the situations both domestically and abroad by the strategic environmental assessment (SEA) approach and also conducted comprehensive evaluations of garbage disposal in Changchun City. On the basis of this study, we found that SEA is of great importance in the municipal solid waste disposal. Moreover, with the rapid socioeconomic development of Changchun City, municipal solid waste production increases on an annual basis, and thus, good waste management planning is of great significance. Considering the situation of the economic development of Changchun City, garbage disposal was handled mainly in the major sanitary landfills with appropriate use of incineration technology. This plan is environmentally friendly at a relatively high degree and has met the requirements of minimum investment. It also takes into account the requirements of the development of incineration technology. Regarding environmental pollution in terms of groundwater pollution and atmospheric pollution, this plan is a feasible one by meeting various requirements with low environmental impact among the three plans discussed in this study.

    The objective of this study was to assess the overall health, including sexual and reproductive health (SRH) knowledge and needs, sexual behaviors, and testicular health practices among young minority males. Anonymous questionnaires were administered to 18- to 25-year-old males receiving services at health clinics in a large southwestern U.S. city. The survey was completed by 258 males with a mean age of 20.8 years. Most young males (67.1%) identified as African American, and 32.9% as Hispanic. Results suggest study participants lack SRH knowledge related to pregnancy and condom effectiveness, and engage in risky sexual behavior including not using birth control at their last sexual encounter. Although 21.6% of participants had a sexually transmitted infection (STI) in the past year, approximately 80% perceived their STI/HIV risk as very low or low. Respondents had low engagement and lack of knowledge of testicular health practices. The majority of respondents (71.1%) reported having been in a physical fight one or more times and 18.1% reported being victims of intimate partner violence. These data support a need for comprehensive health services for minority young males.

  2. Comprehensive assessment of flexible-ligand docking algorithms: current effectiveness and challenges.

    2017-03-14

    Protein-ligand docking has been playing an important role in modern drug discovery. To model drug-target binding in real systems, a number of flexible-ligand docking algorithms with different sampling strategies and scoring methods have been subsequently developed over the past three decades, while rigid-ligand docking is still being used because of its compelling computational efficiency. Here, a comprehensive assessment has been conducted to investigate the effectiveness of flexible-ligand docking versus rigid-ligand docking for three representative docking algorithms (global optimization, incremental construction and multi-conformer docking) in virtual screening and pose prediction on the Directory of Useful Decoys. It was found that overall flexible-ligand docking did not achieve a statistically significant improvement in enrichments over rigid-ligand docking in virtual screening, but all docking programs significantly improved the success rates when considering ligand flexibility in pose prediction. The worse effectiveness of flexible-ligand docking in virtual screening than in pose prediction suggests that the challenges of current docking algorithms exist in ranking more than docking, although the use of flexible-ligand docking in virtual screening was justified by its better effectiveness for more flexible ligand in virtual screening. Challenges for scoring, including internal energy, charge polarization, entropy and flexibility, were investigated and discussed. An empirical way was also proposed to consider loss of ligand conformational entropy for virtual screening. © The Author 2017. Published by Oxford University Press. All rights reserved.

    In the preceding project 'Life Cycle Assessment of genetically modified products as a basis for a comprehensive assessment of possible environmental effects' for the first time the risks of deliberate release of genetically modified organisms (GMOs) into the environment have been taken into account in a Life Cycle Assessment (LCA). This was performed by a risk assessment in addition to a quantitative impact assessment. As from a methodological perspective this was not satisfactory, the Federal Environment Agency commissioned the C.A.U. GmbH and the Institute of Applied Ecology Freiburg to further develop the impact assessment methodology for the risks of GMOs. Any further development of the methodology of impact assessment in LCAs has to be performed on the basis of the standard EN/ISO 14042. There are 2 options for taking into account risks of deliberate release of GMOs: 1. allocation of the potential effects resulting from the genetic modification on human beings and the environment to existing categories of the impact assessment and attempt to quantify within those existing methods of characterization; 2. development of a new category, e.g. 'effects of genetically modified crop plants'. In order to asses the possibilities under option 1 various models of characterization within the categories human toxicity, ecotoxicity and land use (appropriation of environmental space) have been analyzed. The risks of GMOs identified and dealt with in the preceding study were allocated to these categories. It seemed to be impossible to integrate the risks in existing models of characterization for human toxicity and ecotoxicity, as these are based on exposure and impact factors. The development of a factor for exposure seems possible for GMOs, however a suitable impact factor is not possible to generate. In addition it was analyzed if in other impact categories which are difficult to quantify any solutions for operationalization exist. This does not seem to be the case. As a

    2013-01-01

    People with intellectual disability (ID) comprise 2-3% of the Australian population. They mostly rely on their GP for primary health care. In rural areas where there are issues with health workforce shortages, there is a risk that people with ID may not get timely access to primary care or may not be aware of the range of healthcare services available to support them. Internationally, research has shown that regular health assessments are beneficial for people with ID. Annual comprehensive health assessments (ACHAs) have been shown to result in increased detection of medical conditions and could assist in reducing the gap in mortality between people with ID and the broader population. In Australia, people with ID have been eligible to access ACHAs under Medicare since 2007. These provide for a regular review of the person's physical, psychological and social functioning. This study explored the extent to which rural people with ID were accessing these ACHAs, and factors which affected their access to ACHAs. In this qualitative study in-depth interviews were conducted with 18 participants including people with ID, carers/support workers and rural doctors. Interviews were then coded and analysed for themes. Seven themes were identified: (1) healthcare barriers in rural areas; (2) cohesion of rural communities; (3) the way rural doctors practice; (4) lack of knowledge/understanding; (5) venturing into new territory; (6) the role of the practice nurse; and (7) the health communication triangle. Despite the well-known problems of lack of services and distance to specialists in rural Australia, there are compensatory factors which were perceived as improving the wellbeing of people with ID, such as increased social cohesion and community connectedness. More education is needed to ensure that the rationale for ACHAs for people with ID is understood and that doctors feel confident to use them. The number of Medicare reforms implemented in a relatively short period

    This article is a compilation of own research performed during the European COoperation in Science and Technology (COST) action 2103: 'Advance Voice Function Assessment', an initiative of voice and speech processing teams consisting of physicists, engineers, and clinicians. This manuscript concerns analyzing largely irregular voicing types, namely substitution voicing (SV) and adductor spasmodic dysphonia (AdSD). A specific perceptual rating scale (IINFVo) was developed, and the Auditory Model Based Pitch Extractor (AMPEX), a piece of software that automatically analyses running speech and generates pitch values in background noise, was applied. The IINFVo perceptual rating scale has been shown to be useful in evaluating SV. The analysis of strongly irregular voices stimulated a modification of the European Laryngological Society's assessment protocol which was originally designed for the common types of (less severe) dysphonia. Acoustic analysis with AMPEX demonstrates that the most informative features are, for SV, the voicing-related acoustic features and, for AdSD, the perturbation measures. Poor correlations between self-assessment and acoustic and perceptual dimensions in the assessment of highly irregular voices argue for a multidimensional approach.

  10. When nature frowns: A comprehensive impact assessment of the 2012 Babessi floods on people’s livelihoods in rural Cameroon

    Full Text Available Floods are the most common natural disasters worldwide. Much of the growing literature on the impact of floods, especially in developed countries, and to a lesser extent in rural areas of developing countries, concentrates on economic rather than a comprehensive assessment of combined effects on people’s livelihoods. Holistic floods impact assessments are often done long after the shock, raising problems of data reliability following long recall periods, although post-disaster needs assessments when carried out earlier can facilitate appropriate disaster recovery, relief and reconstruction activities. We applied the sustainable livelihoods framework as a comprehensive approach to assess the impacts of the Babessi floods in 2012 on livelihoods in rural (north western region of Cameroon 6 weeks after the floods. Using a structured questionnaire, data was collected from victims before and after the floods, using recall methods. A matched sample of nonvictims randomly selected from the same village as the victims was used to assess vulnerability to the floods by household type. Floods were found to have serious economic, social, human and food security impacts on victims. Both government and nongovernmental support were jointly crucial for household recovery. Comparatively observed high levels of recovery were attributed to the low loss of human lives. The article concludes with the need for comprehensive approaches to floods impact assessments.

    Elucidating the complex mechanisms by which harsh parenting increases risk of child psychopathology is key to targeted prevention. This requires nuanced methods that capture the varied perceptions and experiences of diverse families. The Family Socialization Interview—Revised (FSI-R), adapted from an interview developed by Dodge et al. (Child Development, 65,649–665,1994), is a comprehensive, semi-structured interview for characterizing methods of parental discipline used with young children. The FSI-R coding system systematically rates parenting style, usual discipline techniques, and most intense physical and psychological discipline based on rater judgment across two eras: (1) birth to the previous year, and (2) the previous year to present. The current study examined the psychometric properties of the FSI-R in a diverse, high-risk community sample of 386 mothers and their children, ages 3 to 6 years. Interrater reliability was good to excellent for codes capturing physically and psychologically harsh parenting, and restrictive/punitive parenting styles. Findings supported the FSI-R’s convergent and incremental validity. Importantly, the FSI-R demonstrated incremental utility, explaining unique variance in children’s externalizing and internalizing symptoms beyond that explained by traditional surveys and observed parenting. The FSI-R appeared particularly promising for capturing risk associated with young children’s depressive symptoms, as these were generally not significantly associated with other measures of harsh parenting. Overall, findings support the added value of the FSI-R within a multi-method assessment of disciplinary practices across early child development. Future implications for prevention are discussed.

    Full Text Available Background: Pharmacists are currently providing comprehensive medication management in the outpatient setting. However, there is little documented evidence demonstrating pharmacists are generating further improved health outcomes utilizing non-pharmacologic support, such as fitness and nutrition counseling. The objective of this study is to determine if a pharmacist-led wellness program with medication management and lifestyle modifications through fitness and nutrition coaching can lead to improved biometric markers. Methods: The wellness program targeted corporate employees and was offered in a corporate headquarters' setting with an on-site workout facility. The program was expected to recruit approximately 15 patients into the wellness program consisting of two treatment arms. The standard group featured nutrition-based classes, medication therapy management and fitness education. The intervention group performed the standard group's activities plus direct, supervised fitness training once weekly. Measured biometric markers were assessed at baseline, 3.5 months, and 7 months and included body mass index (BMI, waist circumference (WC, fasting blood glucose (FBG, systolic and diastolic blood pressure (SBP and DBP, and full lipid panel (TC, TG, HDL, and LDL. Results: Seventeen patients were enrolled in the study. The standard group (n = 11 and intervention group (n = 6 had relatively similar biometric markers at baseline. Seven total patients completed the study (4 from standard group, 3 from intervention group. The majority of biometric markers improved in both groups, and BP and LDL control was maintained for all who completed the study. Conclusion: These data suggest that a licensed pharmacist with certified personal trainer credentials may be capable of maintaining biometric markers at healthy levels and improving where necessary in an employee wellness program through one-on-one medication, fitness and nutrition support.

    The Faiyum Oasis in the Western Desert of Egypt is famous for its palaeontological localities (Cenozoic whales, primates, etc.) of global importance, but its geological heritage has been not studied in the modern theoretical frame. The new investigation based on the field studies and the literature review permits comprehensive assessment of the geological heritage diversity in this oasis. For this purposes, unique geological features are inventoried with establishment of their geological essence, rank, relative abundance, and intrinsic diversity. As a result, the existence of ten geological heritage types in the Faiyum Oasis is found. These include palaeontological, palaeogeographical, geomorphological, stratigraphical, sedimentary (merged with mineralogical), hydrological coupled with geochemical, igneous, and economical types. From them, the palaeontological and palaeogeographical types are ranked globally, and the geomorphological and hydrological types are ranked nationally. The other types are either of regional (provincial) or local importance. Some hills and cliffs can serve as viewpoint sites for observation of the local geological landscape. The relative abundance and the intrinsic diversity of the unique geological features vary between low and high. Generally, the concentration of this geological heritage in the Faiyum Oasis permits recognition of the geodiversity hotspot that requires conservation and use for tourism purposes. The protected areas located in the oasis and the existing tourism programs do not offer geoconservation and geotourism activities for the entire hotspot. The possible solution of this problem would be creation of a large geopark similar in its design to the Jeju Island Geopark in South Korea. There are important premises for geotourism development in the Faiyum Oasis and its combination with the archaeological and industrial tourism. Nature conservation failures in this geopark should be avoided; some recommendations are given on

    2013-07-01

    The main objective of this work was to design a comprehensive dosimetry package that would keep all aspects of internal dose calculation within the framework of a single software environment and that would be applicable for a variety of dose calculation approaches. Our MATLAB-based graphical user interface (GUI) can be used for processing data obtained using pure planar, pure SPECT, or hybrid planar/SPECT imaging. Time-activity data for source regions are obtained using a set of tools that allow the user to reconstruct SPECT images, load images, coregister a series of planar images, and to perform two-dimensional and three-dimensional image segmentation. Curve fits are applied to the acquired time-activity data to construct time-activity curves, which are then integrated to obtain time-integrated activity coefficients. Subsequently, dose estimates are made using one of three methods. The organ level dose calculation subGUI calculates mean organ doses that are equivalent to dose assessment performed by OLINDA/EXM. Voxelized dose calculation options, which include the voxel S value approach and Monte Carlo simulation using the EGSnrc user code DOSXYZnrc, are available within the process 3D image data subGUI. The developed internal dosimetry software package provides an assortment of tools for every step in the dose calculation process, eliminating the need for manual data transfer between programs. This saves times and minimizes user errors, while offering a versatility that can be used to efficiently perform patient-specific internal dose calculations in a variety of clinical situations.

    Soil amendments, such as compost and manure, can be applied to grasslands to improve soil conditions and enhance aboveground net primary productivity. Applying such amendments can also lead to soil carbon (C) sequestration and, when materials are diverted from waste streams (e.g., landfills, manure lagoons), can offset greenhouse gas (GHG) emissions. However, amendment production and application is also associated with GHG emissions, and the net impact of these amendments remains unclear. To investigate the potential for soil amendments to reduce net GHG emissions, we developed a comprehensive, field-scale life cycle assessment (LCA) model. The LCA includes GHG (i.e., CO2, CH4, N2O) emissions of soil amendment production, application, and ecosystem response. Emissions avoided by diverting materials from landfills or manure management systems are also considered. We developed the model using field observations from grazed annual grassland in northern California (e.g., soil C; above- and belowground net primary productivity; C:N ratios; trace gas emissions from soils, manure piles, and composting), CENTURY model simulations (e.g., long-term soil C and trace gas emissions from soils under various land management strategies), and literature values (e.g., GHG emissions from transportation, inorganic fertilizer production, composting, and enteric fermentation). The LCA quantifies and contrasts the potential net GHG impacts of applying compost, manure, and commercial inorganic fertilizer to grazing lands. To estimate the LCA uncertainty, sensitivity tests were performed on the most widely ranging or highly uncertain parameters (e.g., compost materials, landfill emissions, manure management system emissions). Finally, our results are scaled-up to assess the feasibility and potential impacts of large-scale adoption of soil amendment application as a land-management strategy in California. Our base case results indicate that C sinks and emissions offsets associated with

    The wide variation in performance among the elderly leads to the search for a suitable instrument to identify the necessary support. The aim of this study was to examine the scope of independent functioning of the elderly and to indicate the necessary support using basic instruments, Comprehensive Geriatric Assessment (CGA) and EASY-Care Standard 2010. For statistical analysis were qualified 101 questionnaires of patients from oncological surgery clinic. The study group was dominated by women (79.2%). The average age for the entire group was 74.7 ± 7.5 years. In terms of basic life activities (Barthel Index), 75.2% of the elderly performed most of their activities independently. The Lawton IADL (Instrumental Activity of Daily Living Scale) median was 25 points. Moderate depression (Geriatric Depression Scale) reported 37.6% of the group. The influence of age, education, mode of movement and efficiency in basic and instrumental life activities and depression (Geriatric Depression Scale) was demonstrated in the results in three scales of the EASY-Care Standard 2010 questionnaire: Independence score, Risk of break down in care and Risk of falls. There was no difference in terms of gender and the nature of the residence. The study group of the elderly was characterised by a good level of efficiency in basic and instrumental activities of daily living. Questionnaire EASY-Care Standard 2010 enables to identify functional limitations of the elderly that may form the basis for planning individual support. © 2015 Nordic College of Caring Science.

    The implementation of resource management strategies aimed at reducing the impacts of the anthropogenic activities system requires a comprehensive approach to evaluate on the whole the environmental burdens of productive processes and to identify the best recovery strategies from both an environmental and an economic point of view. In this framework, an analytical methodology based on the integration of Life Cycle Assessment (LCA), ExternE and Comprehensive Analysis was developed to perform an in-depth investigation of energy systems. The LCA methodology, largely utilised by the international scientific community for the assessment of the environmental performances of technologies, combined with Comprehensive Analysis allows modelling the overall system of anthropogenic activities, as well as sub-systems, the economic consequences of the whole set of environmental damages. Moreover, internalising external costs into partial equilibrium models, as those utilised by Comprehensive Analysis, can be useful to identify the best paths for implementing technology innovation and strategies aimed to a more sustainable energy supply and use. This paper presents an integrated application of these three methodologies to a local scale case study (the Val D'Agri area in Basilicata, Southern Italy), aimed to better characterise the environmental impacts of the energy system, with particular reference to extraction activities. The innovative methodological approach utilised takes advantage from the strength points of each methodology with an added value coming from their integration as emphasised by the main results obtained by the scenario analysis.

    Using a component processes task (CPT) that differentiates between higher-level cognitive processes of reading comprehension provides important advantages over commonly used general reading comprehension assessments. The present study contributes to further development of the CPT by evaluating the relative contributions of its components (text memory, text inferencing, and knowledge integration) and working memory to general reading comprehension within a single study using path analyses. Participants were 173 third- and fourth-grade children. As hypothesized, knowledge integration was the only component of the CPT that directly contributed to reading comprehension, indicating that the text-inferencing component did not assess inferential processes related to reading comprehension. Working memory was a significant predictor of reading comprehension over and above the component processes. Future research should focus on finding ways to ensure that the text-inferencing component taps into processes important for reading comprehension.

    Full Text Available In order to propose a comprehensive corrosion risk evaluation model based on an analysis of the corrosion risk of sea water pipe systems of ships in service,the modes of potential corrosion and their causes were first analyzed by identifying the origins of the inner and outer corrosion of the sea water pipe systems. In accordance with the matrixes of corrosion occurrence possibility and corrosion risk consequence,a corrosion risk matrix was established for a sea water pipe system. The method for the quantitative evaluation value of each mode of corrosion possibly occurring in a sea water pipe system was then presented. The comprehensive evaluation model of the corrosion was first built using the Analytical Hierarchy Process(AHP,which can be used for the comprehensive corrosion evaluation. The results show that the comprehensive evaluation value will be expressed as the corrosion risk level and corrosion-induced consequence of the sea water pipe system. This will be very useful for accurately protecting the sea water pipe systems of ships in service from corrosion,thereby attaining the goals of economy,rationality and timeliness.

    This final report summarizes research undertaken collaboratively between Princeton University, the NOAA Geophysical Fluid Dynamics Laboratory on the Princeton University campus, the State University of New York at Stony Brook, and the University of California, Los Angeles between September 1, 2000, and November 30, 2006, to do fundamental research on ocean iron fertilization as a means to enhance the net oceanic uptake of CO2 from the atmosphere. The approach we proposed was to develop and apply a suite of coupled physical-ecological-biogeochemical models in order to (i) determine to what extent enhanced carbon fixation from iron fertilization will lead to an increase in the oceanic uptake of atmospheric CO2 and how long this carbon will remain sequestered (efficiency), and (ii) examine the changes in ocean ecology and natural biogeochemical cycles resulting from iron fertilization (consequences). The award was funded in two separate three-year installments: September 1, 2000 to November 30, 2003, for a project entitled “Ocean carbon sequestration by fertilization: An integrated biogeochemical assessment.” A final report was submitted for this at the end of 2003 and is included here as Appendix 1; and, December 1, 2003 to November 30, 2006, for a follow-on project under the same grant number entitled “Carbon sequestration by patch fertilization: A comprehensive assessment using coupled physical-ecological-biogeochemical models.” This report focuses primarily on the progress we made during the second period of funding subsequent to the work reported on in Appendix 1. When we began this project, we were thinking almost exclusively in terms of long-term fertilization over large regions of the ocean such as the Southern Ocean, with much of our focus being on how ocean circulation and biogeochemical cycling would interact to control the response to a given fertilization scenario. Our research on these types of scenarios, which was carried out largely during the

    2014-01-01

    For many years, the issue of the legal form of the new climate agreement has hovered over the international negotiations. Countries have insisted on first discussing substance. Indeed, it is here that the main divergences remain. However, one year out from the Paris climate conference, it is time to open the discussion on the legal form of the final agreement. The issue of legal form is often reduced to the negotiation of a 'binding' or 'non-binding' agreement. The bindingness of an international environmental agreement however depends on multiple parameters. We propose four parameters to be considered: the form of the core agreement; the 'anchoring' of commitments; mechanisms for transparency, accountability and facilitation; and mechanisms for compliance. Parties should assess pros and cons of these options, and the agreement be optimised across all four. Negotiations appear to be heading towards a hybrid agreement. Some provisions would be contained in a core agreement, and some in implementing documents such as decisions or schedules. This structure can help to balance legal certainty with flexibility. The core agreement should contain a binding provision to implement and regularly update a 'nationally determined contribution' (NDC). If these NDCs were to be housed outside the agreement, this could give more flexibility on their content, submission and updating. The core agreement should contain strong provisions on transparency, accountability and facilitation, including independent institutional arrangements (a Transparency Committee). At this stage in global cooperation and given inherent weaknesses in international environmental law, a punitive compliance mechanism seems unfeasible. However, the agreement should contain a compliance mechanism regarding procedural obligations, such as submission and updating of NDCs. (authors)

    On the macro level, the structural properties of the network and the electrical characteristics of the micro components determine the risk of cascading failures. And the cascading failures, as a process with dynamic development, not only the direct risk but also potential risk should be considered. In this paper, comprehensively considered the direct risk and potential risk of failures based on uncertain risk analysis theory and connection number theory, quantified uncertain correlation by the node degree and node clustering coefficient, then established a comprehensive risk indicator of failure. The proposed method has been proved by simulation on the actual power grid. Modeling a network according to the actual power grid, and verified the rationality of the proposed method.

    Although the extant literature provides robust evidence of the influence of language exposure and socioeconomic status (SES) on language acquisition, it is unknown how sensitive the early receptive vocabulary system is to these factors. The current study investigates effects of minimal second language exposure and SES on the comprehension vocabulary of 16-month-old children in the language in which they receive the greatest exposure. Study 1 revealed minimal second language exposure and SES exert significant and independent effects on a direct measure of vocabulary comprehension in English-dominant and English monolingual children (N = 72). In Study 2, we replicated the effect of minimal second language exposure in Spanish-dominant and Spanish monolingual children (N = 86), however no effect of SES on vocabulary was obtained. Our results emphasize the sensitivity of the language system to minimal changes in the environment in early development. PMID:26957947

    We review briefly the fundamental equations of a semimicroscopic core-particle coupling method that makes no reference to an intrinsic system of coordinates. We then demonstrate how an intrinsic system can be introduced in the strong coupling limit so as to yield a completely equivalent formulation. It is emphasized that the conventional core-particle coupling calculation introduces a further approximation that avoids what has hitherto been the most time-consuming feature of the full theory, and that this approximation can be introduced either in the intrinsic system, the usual case, or in the laboratory system, our preference. A new algorithm is described for the full theory that largely removes the difference in complexity between the two types of calculation. Comparison of the full and approximate theories for some representative cases provides a basis for the assessment of the accuracy of the traditional approach. We find that for well-deformed nuclei, e.g., 157 Gd and 157 Tb, the core-coupling method and the full theory give similar results. copyright 1997 The American Physical Society

    Purpose: To promote the rational use of scarce research funding, scholars have developed methods for the systematic identification and prioritization of health research needs. The Radiation Oncology Institute commissioned an independent, comprehensive assessment of research needs for the advancement of radiation oncology care. Methods and Materials: The research needs assessment used a mixed-method, qualitative and quantitative social scientific approach, including structured interviews with diverse stakeholders, focus groups, surveys of American Society for Radiation Oncology (ASTRO) members, and a prioritization exercise using a modified Delphi technique. Results: Six co-equal priorities were identified: (1) Identify and develop communication strategies to help patients and others better understand radiation therapy; (2) Establish a set of quality indicators for major radiation oncology procedures and evaluate their use in radiation oncology delivery; (3) Identify best practices for the management of radiation toxicity and issues in cancer survivorship; (4) Conduct comparative effectiveness studies related to radiation therapy that consider clinical benefit, toxicity (including quality of life), and other outcomes; (5) Assess the value of radiation therapy; and (6) Develop a radiation oncology registry. Conclusions: To our knowledge, this prioritization exercise is the only comprehensive and methodologically rigorous assessment of research needs in the field of radiation oncology. Broad dissemination of these findings is critical to maximally leverage the impact of this work, particularly because grant funding decisions are often made by committees on which highly specialized disciplines such as radiation oncology are not well represented.

    Objective: To investigate the comprehensive nutritional status and diet behavior of middle aged and elderly women with osteoporosis, and thereby to explore the relationship between diet behavior and comprehensive nutritional status. Methods: 311 middle-aged and elderly women with osteoporosis in Chengdu were included in this study. Mini Nutritional Assessment (MNA) was applied to assess their comprehensive nutritional status. Information of social-demographic characteristics and diet behavior (about meals, snacks and water drinking, etc.) of the subjects was collected by questionnaire. Chi square test was used to assess the differences in nutritional status among patients who have different eating behaviors. Logistic regression analysis was performed to evaluate the relationship between diet behaviors and comprehensive nutritional status. Results: The mean MNA score of subjects was 25.8±2.5. 20.3% (63/311) of the subjets were at risk of potential malnutrition, but there was no malnourished subjects found. 46.9% (46/311) of the subjects were in good appetite. 95.2% (296/311) of them had a fixed food intake each meal. 65.8% (198/311) of them had snacks every day, and the most common choice was fruit (86.4% (248/287)). 54.8% (165/311) of them had initiative drinking water habits, and the most common choice was plain boiled water (79.9%, 246/308). 76.5% (238/311) of them had daily portable water less than 1 500 ml. After adjusting the effects of age, occupation and education level, bad appetite ( OR= 3.50, 95% CI: 1.18-10.62), unfixed food intake ( OR= 7.27, 95% CI: 1.40-35.83), and seldom or never intake of snack ( OR= 3.71, 95% CI: 1.42-9.72) were risk factors for malnutrition risk, while tea drinking was protective factor( OR= 0.31, 95% CI: 0.11-0.93). Conclusion: Risk of potential malnutrition and unhealthy diet behavior among the middle aged and elderly women with osteoporosis should be paid more attention. Unhealtghy diet behavior has a negative effect on their

    In this paper we present the development and usability of an electronic health record (EHR) system in a comprehensive dental clinic.The graphic user interface of the system was designed to consider the concept of cognitive ergonomics.The cognitive task analysis was used to evaluate the user interface of the EHR by identifying all sub-tasks and classifying them into mental or physical operators, and to predict task execution time required to perform the given task. We randomly selected 30 cases that had oral examinations for routine clinical care in a comprehensive dental clinic. The results were based on the analysis of 4 prototypical tasks performed by ten EHR users. The results showed that on average a user needed to go through 27 steps to complete all tasks for one case. To perform all 4 tasks of 30 cases, they spent about 91 min (independent of system response time) for data entry, of which 51.8 min were spent on more effortful mental operators. In conclusion, the user interface can be improved by reducing the percentage of mental effort required for the tasks.

    To develop and psychometrically evaluate an audio digitised tool for assessment of comprehension of informed consent among low-literacy Gambian research participants. We conducted this study in the Gambia where a high illiteracy rate and absence of standardised writing formats of local languages pose major challenges for research participants to comprehend consent information. We developed a 34-item questionnaire to assess participants' comprehension of key elements of informed consent. The questionnaire was face validated and content validated by experienced researchers. To bypass the challenge of a lack of standardised writing formats, we audiorecorded the questionnaire in three major Gambian languages: Mandinka, Wolof and Fula. The questionnaire was further developed into an audio computer-assisted interview format. The digitised questionnaire was administered to 250 participants enrolled in two clinical trials in the urban and rural areas of the Gambia. One week after first administration, the questionnaire was readministered to half of the participants who were randomly selected. Participants were eligible if enrolled in the parent trials and could speak any of the three major Gambian languages. The primary outcome measure was reliability and validity of the questionnaire. Item reduction by factor analysis showed that 21 of the question items have strong factor loadings. These were retained along with five other items which were fundamental components of informed consent. The 26-item questionnaire has high internal consistency with a Cronbach's α of 0.73-0.79 and an intraclass correlation coefficient of 0.94 (95% CI 0.923 to 0.954). Hypotheses testing also showed that the questionnaire has a positive correlation with a similar questionnaire and discriminates between participants with and without education. We have developed a reliable and valid measure of comprehension of informed consent information for the Gambian context, which might be easily adapted to

    Full Text Available AbstractPurpose: To study reading comprehension performance profiles of children with dyslexia as well as language-based learning disability by means of retelling tasks. Method: 105 children from second to fifth grades of elementary school were gathered into six groups: Dyslexia group (D; n=19, Language-based learning disability group (LBLD; n=16; their respective control groups paired according to different variables - age, gender, grade and school system (public or private (D-control and LBLD-control; and other control groups paired according to different reading accuracy (D-accuracy; LBLD-accuracy. All of the children read an expository text and orally retold the story as they understood it. The analysis quantified propositions (main ideas and details and retold links. A retelling reference standard (3-0 was also established from the best to the worst performance. We compared both clinical groups (D and LBLD with their respective control groups by means of Mann-Whitney tests.Results: D showed the same total of propositions, links and reference standards as D-control, but performed better than D-accuracy in macro structural (total of links and super structural (retelling reference standard measures. Results suggest that dyslexic children are able to use their linguistic competence and their own background knowledge to minimize the effects of their decoding deficit, especially at the highest text processing levels. LBLD performed worse than LBLD-control in all of the retelling measures and LBLD showed worse performance than LBLD-accuracy in the total retold links and retelling reference standard. Those results suggest that both decoding and linguistic difficulties affect reading comprehension. Moreover, the linguistic deficits presented by LBLD students do not allow these pupils to perform as competently in terms of text comprehension as the children with dyslexia do. Thus, failure in the macro and super-structural information processing of the

    The first four levels of Bloom's taxonomy were used to create quiz questions designed to assess student learning of the gross anatomy, histology, and physiology of the gastrointestinal (GI) system. Information on GI histology and physiology was presented to separate samples of medical, dental, and podiatry students in computer based tutorials where the information from the two disciplines was presented either separately or in an integrated fashion. All students were taught GI gross anatomy prior to this study by course faculty as part of the required curriculum of their respective program. Student responses to the quiz questions were analyzed to assess both the validity of Bloom's cumulative hierarchy and the effectiveness of an integrated curriculum. No statistically significant differences were found between quiz scores from students who received the integrated tutorial and from those who received the separate tutorials. Multiple regression analyses provided partial support for a cumulative hierarchy where scores on the lower levels of Bloom's taxonomy predicted scores on higher levels. Notably, in the majority of regression analyses, the comprehension score was the key foundational predictor for application and analysis scores. This study supports the suggestion that educators increase the number of comprehension level questions, even at the expense of knowledge level questions, in course assessments both to evaluate lower order cognitive skills and also as a predictor of success on questions requiring application and analysis levels of the higher order cognitive skills of Bloom's taxonomy.

    2016-01-01

    Abstract The prevalence of cognitive impairment and orthostatic hypotension (OH) increases with age, but the results of studies that assessed possible associations between them are inconsistent. The aim of this study is to assess possible associations between cognitive impairment and OH in patients ≥65 years of age who underwent a comprehensive geriatric assessment. A retrospective analysis was conducted of the computerized medical records of the study population from 2005 to 2013. Data collected included blood pressure measurements that enabled the calculation of OH, results of the mini-mental state examination (MMSE), results of the Montreal cognitive assessment (MoCA) test, and cognitive diagnoses that were determined over the course of the assessment. The rate of OH in the study population of 571 adults was 32.1%. The mean MMSE score was 22.5 ± 5.2 among participants with OH and 21.6 ± 5.8 among those without OH (P = 0.09). The absence of a significant association between OH and MMSE remained after adjusting the MMSE score for age and education level. The mean MoCA score was 16.4 ± 5.0 among participants with OH and 16.4 ± 4.8 among those without (P = 0.33). The prevalence of OH was 39% among participants without cognitive impairment, 28.9% among those with mild cognitive impairment (MCI), and 30.6% among those with dementia (P = 0.13). There was no association between OH and cognitive impairment in adults who underwent a comprehensive geriatric assessment. PMID:27442658

  4. Rapid Damage Assessment by Means of Multi-Temporal SAR — A Comprehensive Review and Outlook to Sentinel-1

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available Fast crisis response after natural disasters, such as earthquakes and tropical storms, is necessary to support, for instance, rescue, humanitarian, and reconstruction operations in the crisis area. Therefore, rapid damage mapping after a disaster is crucial, i.e., to detect the affected area, including grade and type of damage. Thereby, satellite remote sensing plays a key role due to its fast response, wide field of view, and low cost. With the increasing availability of remote sensing data, numerous methods have been developed for damage assessment. This article gives a comprehensive review of these techniques focusing on multi-temporal SAR procedures for rapid damage assessment: interferometric coherence and intensity correlation. The review is divided into six parts: First, methods based on coherence; second, the ones using intensity correlation; and third, techniques using both methodologies combined to increase the accuracy of the damage assessment are reviewed. Next, studies using additional data (e.g., GIS and optical imagery to support the damage assessment and increase its accuracy are reported. Moreover, selected studies on post-event SAR damage assessment techniques and examples of other applications of the interferometric coherence are presented. Then, the preconditions for a successful worldwide application of multi-temporal SAR methods for damage assessment and the limitations of current SAR satellite missions are reported. Finally, an outlook to the Sentinel-1 SAR mission shows possible solutions of these limitations, enabling a worldwide applicability of the presented damage assessment methods.

    Despite significant advancements in computational fluid dynamics and their coupling with computational structural dynamics (= CSD, or comprehensive codes) for rotorcraft applications, CSD codes with their engineering level of modeling the rotor blade dynamics, the unsteady sectional aerodynamics and the vortical wake are still the workhorse for the majority of applications. This is especially true when a large number of parameter variations is to be performed and their impact on performance, structural loads, vibration and noise is to be judged in an approximate yet reliable and as accurate as possible manner. In this paper, the capabilities of such codes are evaluated using the HART II Inter- national Workshop data base, focusing on a typical descent operating condition which includes strong blade-vortex interactions. Three cases are of interest: the baseline case and two cases with 3/rev higher harmonic blade root pitch control (HHC) with different control phases employed. One setting is for minimum blade-vortex interaction noise radiation and the other one for minimum vibration generation. The challenge is to correctly predict the wake physics - especially for the cases with HHC - and all the dynamics, aerodynamics, modifications of the wake structure and the aero-acoustics coming with it. It is observed that the comprehensive codes used today have a surprisingly good predictive capability when they appropriately account for all of the physics involved. The minimum requirements to obtain these results are outlined.

    Significant advancements in computational fluid dynamics (CFD) and their coupling with computational structural dynamics (CSD, or comprehensive codes) for rotorcraft applications have been achieved recently. Despite this, CSD codes with their engineering level of modeling the rotor blade dynamics, the unsteady sectional aerodynamics and the vortical wake are still the workhorse for the majority of applications. This is especially true when a large number of parameter variations is to be performed and their impact on performance, structural loads, vibration and noise is to be judged in an approximate yet reliable and as accurate as possible manner. In this article, the capabilities of such codes are evaluated using the HART II International Workshop database, focusing on a typical descent operating condition which includes strong blade-vortex interactions.

    2016-01-01

    There has been an increasing need to conduct investigative safety pharmacology studies to complement regulatory-required studies, particularly as it applies to a comprehensive assessment of cardiovascular (CV) risk. We describe refined methodology using a combination of telemetry and direct signal acquisition to record concomitant peripheral hemodynamics, ECG, and left ventricular (LV) structure (LV chamber size and LV wall thickness) and function, including LV pressure-volume (PV) loops to determine load independent measures of contractility (end systolic elastance, Ees, and preload recruitable stroke work, PRSW) in conscious beagle dogs. Following baseline characterization, 28days of chronic rapid ventricular pacing (RVP) was performed and cardiac function monitored: both as a way to compare measures during development of dysfunction and to characterize feasibility of a model to assess CV safety in animals with underlying cardiac dysfunction. While ±dP/dT decreased within a few days of RVP and remained stable, more comprehensive cardiac function measurements, including Ees and PRSW, provided a more sensitive assessment confirming the value of such endpoints for a more clear functional assessment. After 28days of RVP, the inodilator pimobendan was administered to further demonstrate the ability to detect changes in cardiac function. Expectedly pimobendan caused a leftward shift in the PV loop, improved ejection fraction (EF) and significantly improved Ees and PRSW. In summary, the data show the feasibility and importance in measuring enhanced cardiac functional parameters in conscious normal beagle dogs and further describe a relatively stable cardiac dysfunction model that could be used as an investigative safety pharmacology risk assessment tool.

    National Pollution Discharge Elimination Permit (NPDES)-driven effluent toxicity tests using Ceriodaphnia dubia and fathead minnows were conducted for more than 20 years to assess and monitor the effects of wastewaters at the United States (U.S.) Department of Energy Y-12 National Security Complex (Y-12 Complex) in Oak Ridge, Tennessee. Toxicity testing was also conducted on water samples from East Fork Poplar Creek (EFPC), the wastewater receiving stream, as part of a comprehensive biological monitoring and assessment program. In this paper, we evaluate the roles of this long-term toxicity assessment and monitoring program in the management and ecological recovery of EFPC. Effluent toxicity testing, associated toxicant evaluation studies, and ambient toxicity monitoring were instrumental in identifying toxicant sources at the Y-12 Complex, guiding modifications to wastewater treatment procedures, and assessing the success of various pollution-abatement actions. The elimination of untreated wastewater discharges, the dechlorination of remaining wastewater streams, and the implementation of flow management at the stream headwaters were the primary actions associated with significant reductions in the toxicity of stream water in the upper reaches of EFPC from the late 1980s through mid 1990s. Through time, as regulatory requirements changed and water quality improved, emphasis shifted from comprehensive toxicity assessments to more focused toxicity monitoring efforts. Ambient toxicity testing with C. dubia and fathead minnows was supplemented with less-standardized but more sensitive alternative laboratory toxicity tests and in situ bioassays. The Y-12 Complex biological monitoring experience demonstrates the value of toxicity studies to the management of a wastewater receiving stream.

    Stephan, André; Crawford, Robert H.; Myttenaere, Kristel de

    2013-01-01

    Highlights: • The life cycle energy demand of a passive house (PH) is measured over 100 years. • Embodied, operational and user transport energy demand are considered. • Embodied energy represents the highest energy consumption in all variations. • A PH might not save energy compared to a standard house. • A poorly insulated city apartment can use less energy than a best case suburban PH. - Abstract: Certifications such as the Passive House aim to reduce the final space heating energy demand of residential buildings. The latter are responsible for a significant share of final energy consumption in Europe of which nearly 70% is associated with space conditioning, notably heating. The improvement of the energy efficiency of residential buildings, in terms of space heating, can therefore reduce their total energy demand. However, most certifications totally overlook other energy requirements associated with residential buildings. Studies on passive houses do not take into consideration the embodied energy required to manufacture the building materials, especially the large amount of insulation required to achieve high operational efficiencies. At an urban scale, most passive houses are single family detached houses located in low density suburbs with a high car usage, resulting in considerable transport related energy demand. This paper analyses the total life cycle energy demand of a typical Belgian passive house, comprising embodied, operational and transport energy. It relies on a comprehensive technique developed by Stephan et al. [1] and conducts a parametric analysis as well as a comparison to alternative building types. Results show that current building energy efficiency certifications might not ensure a lower energy demand and can, paradoxically result in an increased energy consumption because of their limited scope. More comprehensive system boundaries should be used to make sure that net energy savings do occur. The embodied energy of passive

    Fletcher, Jack M; Miciak, Jeremy

    2017-02-01

    There is considerable controversy about the necessity of cognitive assessment as part of an evaluation for learning and attention problems. The controversy should be adjudicated through an evaluation of empirical research. We review five sources of evidence commonly provided as support for cognitive assessment as part of the learning disability (LD) identification process, highlighting significant gaps in empirical research and where existing evidence is insufficient to establish the reliability and validity of cognitive assessments used in this way. We conclude that current evidence does not justify routine cognitive assessment for LD identification. As an alternative, we offer an instructional conceptualization of LD: a hybrid model that directly informs intervention and is based on documenting low academic achievement, inadequate response to intensive interventions, and a consideration of exclusionary factors. © The Author 2016.

    Anemia and hypoalbuminemia (HA) are acknowledged independent risk factors for morbidity and mortality in geriatric patients and are associated with nutritional status and frailty. Data exist regarding the association between albumin and frailty, anemia and frailty as well as frailty and nutritional status; however, there is a lack of information on the association between HA, anemia and nutritional status in older people. This study retrospectively analyzed 626 patients admitted to a German geriatrics department (average age 81.1 years, 68.2% female and 31.8% male) for anemia and HA. Data from the comprehensive geriatric assessment (CGA) and from the mini-nutritional assessment (MNA) were available in all patients. Patients with anemia suffered significantly more often from HA (pGeriatric inpatients with anemia should be evaluated in terms of the presence of malnutrition risk and HA.

    Full Text Available In this era of external teacher testing with the intent of ensuring the competence of the teaching force, as well as holding students and institutions accountable for results, the Idaho Comprehensive Literacy Assessment (ICLA stands in sharp contrast. It represents an alternative to external testing of preservice teachers, testing procured from an outside agency unconnected to preservice programs, since it has been developed and is managed by literacy faculty from Idaho’s major institutions of higher learning. This paper provides a brief history of major events in the field of literacy including teacher testing initiatives and policies, which led to the creation of the ICLA. A description of the ICLA assessment and its construction is provided, along with a report of initial performance. Implications and policy consequences of this approach are explored.

    The percentage of patients receiving haemodialysis (HD) treatment and of patients with Alzheimer's disease (AD) within the elderly population is increasing day by day. Functional dependence, malnutrition, cognitive impairment or depression impairs the quality of life and increases mortality in both diseases. This study aims to assess HD and AD patients through comprehensive geriatric assessment (CGA) and compare their results. A total of 579 patients (121 HD, 188 AD patients and 270 control subjects) over the age of 65, who were followed at geriatric and nephrology departments between January 2011 and July 2012, were included in this prospective cross-sectional study. Mini-Mental State Examination, Mini-Nutritional Assessment, Geriatric Depression Scale and basic and Instrumental Activities of Daily Living indexes were applied to all patients. The results obtained were compared among the patient groups. The mean age of the participants was 72.6 ± 8.2. Based on the CGA findings, the results for both groups were considerably different from control group. While depression scores were observed higher in HD patients than in AD patients, cognition, nutrition and functional capacity were mostly affected in AD patients. The management of geriatric HD patients is substantially complex. Depression, cognitive impairment and decrease in functional capacity can often be overlooked, so findings may be ascribed to underlying kidney impairment. Therefore, comprehensive geriatric assessment should be regularly performed in HD patients in order to detect problems at an early stage, to take necessary preventative measures, to initiate treatment as soon as possible and to enhance quality of life.

    The impact of a quality-assessment dashboard and individualized pharmacist performance feedback on the adherence of order verification was evaluated. A before-and-after study was conducted at a 1,440-bed academic medical center. Adherence of order verification was defined as orders verified according to institution-derived, medication-related guidelines and policies. Formulas were developed to assess the adherence of verified orders to dosing guidelines using patient-specific height, weight, and serum creatinine clearance values from the electronic medical record at the time of pharmacist verification. A total of 5 medications were assessed by the formulas for adherence and displayed on the dashboard: ampicillin-sulbactam, ciprofloxacin, piperacillin-tazobactam, acyclovir, and enoxaparin. Adherence of order verification was assessed before (May 1-July 31, 2015) and after (November 1, 2015-January 31, 2016) individualized performance feedback was given based on trends identified by the quality-assessment dashboard. There was a significant increase in the overall adherence rate postintervention (90.1% versus 91.9%, p = 0.040). Among the 34 pharmacists who participated, the percentage of pharmacists with at least 90% overall adherence increased postintervention (52.9% versus 70.6%, p = 0.103). Time to verification was similar before and after the study intervention (median, 6.0 minutes; interquartile range, 3-13 minutes). The rate of documentation for nonadherent orders increased significantly postintervention (57.1% versus 68.5%, p = 0.019). The implementation of the quality-assessment dashboard, educational sessions, and individualized performance feedback significantly improved pharmacist order-verification adherence to institution-derived, medication-related guidelines and policies and the documentation rate of nonadherent orders.

  1. Indicators of bioenergy-related certification schemes – An analysis of the quality and comprehensiveness for assessing local/regional environmental impacts

    International Nuclear Information System (INIS)

    Meyer, Markus A.; Priess, Joerg A.

    2014-01-01

    Bioenergy is receiving increasing attention because it may reduce greenhouse gas emissions, secure and diversify energy supplies and stimulate rural development. The environmental sustainability of bioenergy production systems is often determined through life-cycle assessments that focus on global environmental effects, such as the emission of greenhouse gases or air pollutants. Local/regional environmental impacts, e.g., the impacts on soil or on biodiversity, require site-specific and flexible options for the assessment of environmental sustainability, such as the criteria and indicators used in bioenergy certification schemes. In this study, we compared certification schemes and assessed the indicator quality through the environmental impact categories, using a standardized rating scale to evaluate the indicators. Current certification schemes have limitations in their representation of the environmental systems affected by feedstock production. For example, these schemes predominantly use feasible causal indicators, instead of more reliable but less feasible effect indicators. Furthermore, the comprehensiveness of the depicted environmental systems and the causal links between human land use activities and biophysical processes in these systems have been assessed. Bioenergy certification schemes seem to demonstrate compliance with underlying legislation, such as the EU Renewable Energy Directive, rather than ensure environmental sustainability. Beyond, certification schemes often lack a methodology or thresholds for sustainable biomass use. Lacking thresholds, imprecise causal links and incomplete indicator sets may hamper comparisons of the environmental performances of different feedstocks. To enhance existing certification schemes, we propose combining the strengths of several certification schemes with research-based indicators, to increase the reliability of environmental assessments. - Highlights: • Certification schemes for bioenergy feedstocks are

    Risk assessments and risk management efforts to protect human health and the environment can benefit from early, coordinated research planning by researchers, risk assessors, and risk managers. However, approaches for engaging these and other stakeholders in research planning have not received much attention in the environmental scientific literature. The Comprehensive Environmental Assessment (CEA) approach under development by the United States Environmental Protection Agency (USEPA) is a means to manage complex information and input from diverse stakeholder perspectives on research planning that will ultimately support environmental and human health decision making. The objectives of this article are to 1) describe the outcomes of applying lessons learned from previous CEA applications to planning research on engineered nanomaterial, multiwalled carbon nanotubes (MWCNTs) and 2) discuss new insights and refinements for future efforts to engage stakeholders in research planning for risk assessment and risk management of environmental issues. Although framed in terms of MWCNTs, this discussion is intended to enhance research planning to support assessments for other environmental issues as well. Key insights for research planning include the potential benefits of 1) ensuring that participants have research, risk assessment, and risk management expertise in addition to diverse disciplinary backgrounds; 2) including an early scoping step before rounds of formal ratings; 3) using a familiar numeric scale (e.g., US dollars) versus ordinal rating scales of "importance"; 4) applying virtual communication tools to supplement face-to-face interaction between participants; and 5) refining criteria to guide development of specific, actionable research questions. © 2015 SETAC.

    Structural changes and metabolic stress have been reported on diffusion-weighted magnetic resonance imaging in the cornu ammonis 1 area of the hippocampus in patients with transient global amnesia (TGA), but a consensus on pathogenesis is still lacking. The aim of our study was to perform a comprehensive ultrasound analysis of the cerebrovascular circulation in our population of patients with TGA. One hundred patients with TGA and 50 age- and sex-matched control participants underwent ultrasound examinations of the cervicocranial circulation. The most significant risk factor for TGA was arterial hypertension (P  .05). Rarely detected microembolic signals or a right-left cardiopulmonary shunt excluded an emboligenic mechanism of TGA (P > .05). The internal jugular vein valves were incompetent in 54% of patients with TGA, and this condition was associated with an increased risk of TGA (odds ratio, 4.16; 95% confidence interval, 1.91-9.04). The mean values of the breath holding index and pulsatility index, as parameters of small-vessel function, were within normal ranges and without differences between the TGA and control groups (P > .05). Our ultrasound examination did not detect significant structural atherosclerotic changes of cervicocranial arteries, and an emboligenic mechanism was excluded. Only a significant rise of blood pressure in TGA and significant valvular insufficiency of the internal jugular vein were established. New research should clarify whether these simultaneous functional circulatory changes have relevance for metabolic stress in the cornu ammonis of the hippocampus. © 2017 by the American Institute of Ultrasound in Medicine.

    Recent studies have revealed that the blood of healthy humans is not as sterile as previously supposed. The objective of this study was to provide a comprehensive description of the microbiome present in different fractions of the blood of healthy individuals. The study was conducted in 30 healthy blood donors to the French national blood collection center (Établissement Français du Sang). We have set up a 16S rDNA quantitative polymerase chain reaction assay as well as a 16S targeted metagenomics sequencing pipeline specifically designed to analyze the blood microbiome, which we have used on whole blood as well as on different blood fractions (buffy coat [BC], red blood cells [RBCs], and plasma). Most of the blood bacterial DNA is located in the BC (93.74%), and RBCs contain more bacterial DNA (6.23%) than the plasma (0.03%). The distribution of 16S DNA is different for each fraction and spreads over a relatively broad range among donors. At the phylum level, blood fractions contain bacterial DNA mostly from the Proteobacteria phylum (more than 80%) but also from Actinobacteria, Firmicutes, and Bacteroidetes. At deeper taxonomic levels, there are striking differences between the bacterial profiles of the different blood fractions. We demonstrate that a diversified microbiome exists in healthy blood. This microbiome has most likely an important physiologic role and could be implicated in certain transfusion-transmitted bacterial infections. In this regard, the amount of 16S bacterial DNA or the microbiome profile could be monitored to improve the safety of the blood supply. © 2016 AABB.

    2014-03-31

    The Forest County Potawatomi Community, a federally-recognized Indian Tribe with a strong commitment to the natural environment, sought and obtained funding to investigate energy efficient improvements to its Potawatomi Carter Casino & Hotel and the adjacent Potawatomi Carter C-Store and Smoke Shop. The resulting energy studies recommended energy conservation measures that would collectively reduce energy use by more than 30% at the facilities and would save approximately $200,000 per year in energy costs. Consistent with its commitment to the natural environment, and to advance its goal of energy independence using Carbon free or Carbon neutral renewable resources, the Community has already begun implementing certain measures and continues to seek funding sources necessary to implement the remaining measures.

    2015-03-01

    The purpose of this study was to conduct a baseline assessment of intimate partner violence (IPV) practices in a pediatric hospital system. The Delphi Instrument for Hospital-based Domestic Violence Programs was used to assess the structure and components of the hospital system's IPV practices. Through key stakeholder interviews, we also assessed IPV practices in individual patient care areas. Qualitative analysis of interview data used a grounded theory approach. The hospital scored 17 of 100 points on the Delphi instrument assessment. Key areas of weakness identified by the Delphi instrument and interviews included lack of coordinated provider training and evaluation of IPV-related processes and no standards for IPV screening, safety assessment, and documentation. Most interviewees supported addressing IPV; all identified barriers to IPV screening at individual provider and institutional levels. Institutional barriers included lack of a standardized response to IPV disclosure, need for individualized screening protocols for different patient care settings, lack of standardized provider training, concerns about overextending social work resources, and lack of resources for hospital staff experiencing vicarious trauma. Individual barriers included concern that screening may harm physician-patient-family relationships and the perception that physicians are unwilling to address psychosocial issues. The Delphi Instrument for Hospital-based Domestic Violence Programs identified weaknesses and key areas for improvement in IPV practices. Deficiencies revealed by the Delphi instrument were affirmed by individual interview results. Institutional and individual provider level barriers must be addressed to optimize IPV practices in a pediatric hospital system. Copyright © 2015 by the American Academy of Pediatrics.

  11. A robust and versatile mass spectrometry platform for comprehensive assessment of the thiol redox metabolome

    Directory of Open Access Journals (Sweden)

    2018-06-01

    Full Text Available Several diseases are associated with perturbations in redox signaling and aberrant hydrogen sulfide metabolism, and numerous analytical methods exist for the measurement of the sulfur-containing species affected. However, uncertainty remains about their concentrations and speciation in cells/biofluids, perhaps in part due to differences in sample processing and detection principles. Using ultrahigh-performance liquid chromatography in combination with electrospray-ionization tandem mass spectrometry we here outline a specific and sensitive platform for the simultaneous measurement of 12 analytes, including total and free thiols, their disulfides and sulfide in complex biological matrices such as blood, saliva and urine. Total assay run time is < 10 min, enabling high-throughput analysis. Enhanced sensitivity and avoidance of artifactual thiol oxidation is achieved by taking advantage of the rapid reaction of sulfhydryl groups with N-ethylmaleimide. We optimized the analytical procedure for detection and separation conditions, linearity and precision including three stable isotope labelled standards. Its versatility for future more comprehensive coverage of the thiol redox metabolome was demonstrated by implementing additional analytes such as methanethiol, N-acetylcysteine, and coenzyme A. Apparent plasma sulfide concentrations were found to vary substantially with sample pretreatment and nature of the alkylating agent. In addition to protein binding in the form of mixed disulfides (S-thiolation a significant fraction of aminothiols and sulfide appears to be also non-covalently associated with proteins. Methodological accuracy was tested by comparing the plasma redox status of 10 healthy human volunteers to a well-established protocol optimized for reduced/oxidized glutathione. In a proof-of-principle study a deeper analysis of the thiol redox metabolome including free reduced/oxidized as well as bound thiols and sulfide was performed

  12. Assessment of pulmonary artery pressure by echocardiography—A comprehensive review

    Directory of Open Access Journals (Sweden)

    Sathish Parasuraman

    2016-09-01

    Full Text Available Pulmonary hypertension is a pathological haemodynamic condition defined as an increase in mean pulmonary arterial pressure ≥ 25 mmHg at rest, assessed using gold standard investigation by right heart catheterisation. Pulmonary hypertension could be a complication of cardiac or pulmonary disease, or a primary disorder of small pulmonary arteries. Elevated pulmonary pressure (PAP is associated with increased mortality, irrespective of the aetiology. The gold standard for diagnosis is invasive right heart catheterisation, but this has its own inherent risks. In the past 30 years, immense technological improvements in echocardiography have increased its sensitivity for quantifying pulmonary artery pressure (PAP and it is now recognised as a safe and readily available alternative to right heart catheterisation. In the future, scores combining various echo techniques can approach the gold standard in terms of sensitivity and accuracy, thereby reducing the need for repeated invasive assessments in these patients.

    To assess the environmental impact of As and Hg, bioindicator organisms such as bivalves have been used. Nevertheless, few studies have assessed the impacts of As and Hg in Ruditapes decussatus and Ruditapes philippinarum, which are native and exotic species in Europe, respectively. The main goal of the present study was to assess elements' partitioning and detoxification strategies of R. decussatus and R. philippinarum. Both clams showed a higher capacity to bioconcentrate Hg (BCF 2.29-7.49), when compared to As (0.59-1.09). Furthermore, As accumulation in both species was similar in the soluble and insoluble fractions, while in both species the majority of Hg was found in the insoluble fraction. Clams exposed to As showed different detoxification strategies, since R. decussatus had higher ability to enhance antioxidant enzymes and metallothioneins in order to reduce toxicity, and R.philippinarum increased glutathione S-transferase Ω activity, that catalyzes monomethyl arsenate reduction, the rate-limiting reaction in arsenic biotransformation. When exposed to Hg, R. decussatus presented, higher synthesis of antioxidant enzymes and lower LPO, being able to better tolerate Hg than the exotic species R. philippinarum. Thus under relevant levels of As and Hg contamination our work evidenced the higher ability of R. decussatus to survive and inhabit coastal environments not heavily contaminated by Hg and As.

    2018-03-01

    Full Text Available Under dual pressures of energy and environmental security, sweet sorghum is becoming one of the most promising feedstocks for biofuel production. In the present study, the technical feasibility of sweet sorghum production was assessed in eight agricultural regions in China using the Sweet Sorghum Production Technique Maturity Model. Three top typical agricultural zones were then selected for further sustainability assessment of sweet sorghum production: Northeast China (NEC, Huang-Huai-Hai Basin (HHHB and Ganxin Region (GX. Assessment results demonstrated that NEC exhibited the best sustainable production of sweet sorghum, with a degree of technical maturity value of 0.8066, followed by HHHB and GX, with corresponding values of 0.7531 and 0.6594, respectively. Prospective economic profitability analysis indicated that bioethanol production from sweet sorghum was not feasible using current technologies in China. More efforts are needed to dramatically improve feedstock mechanization logistics while developing new bioethanol productive technology to reduce the total cost. This study provides insight and information to guide further technological development toward profitable industrialization and large-scale sweet sorghum bioethanol production.

    A comprehensive component-level assessment of several strategic and minor metals (SaMMs), including copper, manganese, magnesium, nickel, tin, niobium, light rare earth elements (LREEs; lanthanum, cerium, praseodymium, neodymium, promethium, and samarium), cobalt, silver, tungsten, heavy rare earth elements (yttrium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium), and gold, use in the 2013 model year Ford Fiesta, Focus, Fusion, and F-150 is presented. Representative material contents in cars and light-duty trucks are estimated using comprehensive, component-level data reported by suppliers. Statistical methods are used to accommodate possible errors within the database and provide estimate bounds. Results indicate that there is a high degree of variability in SaMM use and that SaMMs are concentrated in electrical, drivetrain, and suspension subsystems. Results suggest that trucks contain greater amounts of aluminum, nickel, niobium, and silver and significantly greater amounts of magnesium, manganese, gold, and LREEs. We find tin and tungsten use in automobiles to be 3-5 times higher than reported by previous studies which have focused on automotive electronics. Automotive use of strategic and minor metals is substantial, with 2013 vehicle production in the United States, Canada, EU15, and Japan alone accounting for approximately 20% of global production of Mg and Ta and approximately 5% of Al, Cu, and Sn. The data and analysis provide researchers, recyclers, and decision-makers additional insight into the vehicle content of strategic and minor metals of current interest.

    To comprehensively assess thoracic anatomy and pulmonary microcirculation in pulmonary embolism by using computed tomographic (CT) angiography of the pulmonary arteries combined with functional CT imaging of blood flow. Twenty-two patients suspected of having acute pulmonary embolism underwent contrast material-enhanced thin-section electron-beam CT angiography of the pulmonary arteries. In addition, in each patient, a dynamic multisection blood flow CT study was performed on a 7.6-cm lung volume with electrocardiographic gating. Pulmonary blood flow was calculated, and perfusion parameters were visualized on color-coded maps. The color-coded maps and CT angiograms were independently evaluated, segment by segment, by two readers for perfusion deficits and the presence of clots, respectively. The results were compared. Mean pulmonary blood flow was 0.63 mL/min/mL in the occluded segments versus 2.27 mL/min/mL in the nonoccluded segments (P: =.001). The sensitivity and specificity of perfusion maps for the presence of segmental pulmonary embolism compared with those of CT angiography were 75.4% and 82.3%, respectively, with positive and negative predictive values of 79.6% and 84.7%, respectively. The false-negative findings were caused mainly by partial occlusion of vessels. In eight patients, a substantial alternative or additional pathologic entity was diagnosed. By combining CT angiography and dynamic CT imaging, a comprehensive and noninvasive diagnosis of thoracic structure and function is feasible with a single modality.

    To evaluate radiology residents' performance in interpretation and comprehension of breast ultrasonographic descriptors in the Breast Imaging Reporting and Data System (BI-RADS) to suggest the adequate duration of training in breast ultrasonography. A total of 102 radiology residents working in the Department of Radiology were included in this study. They were asked to answer 16 questions about the ultrasonographic lexicon and 11 questions about the BI-RADS category. We analyzed the proportion of correct answers according to the radiology residents’ year of training and duration of breast imaging training. With respect to the duration of breast imaging training, the proportion of correct answers for lexicon descriptors ranged from 77.2% to 81.3% (p = 0.368) and the proportion of correct answers for the BI-RADS category was highest after three-four months of training compared with after one month of training (p = 0.033). The proportion of correct answers for lexicon descriptors and BI-RADS category did not differ significantly according to the year of residency training. Radiology residents' comprehension of the BI-RADS category on breast ultrasonography was not associated with their year of residency training. Based on our findings, radiology residents' assessment of the BI-RADS category was significantly improved with three-four months of training compared with one month of training.

    2004-01-01

    This report presents the results of an environmental assessment of Hydro-Quebec's proposed project to build a new facility on the Peribonka River. The facility includes a run-of-river generating station with an installed capacity of 385 MW. The Quebec Region of the Department of Fisheries and Oceans Canada has conducted an environmental assessment of the project's effects. A summary of the project and the environment in which it will be carried out was presented along with the results of public consultations conducted by Hydro-Quebec. A summary of the main environmental effects was included along with cumulative effects and the effects caused by accidents or malfunctions that may occur. In addition, the terms and conditions of mitigation measures and follow-up programs were described and the significance of any environmental impacts were assessed. The project includes the construction of a 80 metre high dam, two dikes and one spillway upstream of the mouth of the Manouane River. The level of the reservoir would remain at close to its maximum level of 244.2 metres to optimize hydroelectric production. The power house would be integrated into the Hydro-Quebec transmission network. The main impacts of the project would result from the construction of the reservoir, the encroachment caused by associated facilities and the changes in hydrological conditions. This report outlined the current use of lands and resources for traditional purposes by Aboriginals. It also discussed the effects of natural events such as flooding, waves and climate that may cause damage to the facilities. It was determined that the project is not likely to cause significant effects on the renewable resources of the forest and the fisheries. The Department of Fisheries and Oceans, after having taking into account proposed mitigation measures, has rendered a preliminary conclusion which states that the project is not likely to have significant negative environmental effects. 29 refs., 7 tabs., 2

  2. Comprehensive Self-Assessment and Upgrade Program (CSAUP) performance objectives and criteria

    Energy Technology Data Exchange (ETDEWEB)

    1990-05-01

    The US Department of Energy (DOE) has placed strong emphasis on a new way of doing business patterned on the lessons learned in the nuclear power industry after the accident at Three Mile Island Unit 2. The new way relies on strict adherence to policies and procedures, a greatly expanded training program, and much more rigor and formality in operations. Another key element is more visible oversight by upper management and auditability by DOE. Although the Chemical Technology Division (Chem Tech) has functioned in a safe manner since its beginning, the policies and methods of the past are no longer appropriate. Therefore, in accordance with these directives, Chem Tech is improving its operational performance by making a transition to greater formality in the observance of policies and procedures and a more deliberate consideration of the interrelationships between organizations at ORNL. This transition to formality is vitally important because both our staff and our facilities are changing with time. For example, some of the inventors and developers of the processes and facilities in use are now passing the torch'' to the next generation of Chem Tech staff. Our facilities have also served us well for many years, but the newest of these are now over 20 years old All have increasing needs of refurbishment and repair, and some of the older ones need to be replaced. This procedure, based on the lessons learned in the nuclear industry, will enhance Chem Tech's operational performance in some important ways, while maintaining the special factors that have allowed the Chem Tech staff to be creative and successful in the RD D activities.

    Cancer is an age-related disease, and the increase in life expectancy will lead to a progressive increase of cancer cases in the elderly (> or =70 years of age). We have created a group called GONG (Gruppo Oncologico Geriatrico) to apply cancer geriatric assessment in elderly cancer patients, in order to select which of them are eligible for oncological treatment or supportive care only. We applied this model to evaluate 153 patients from March 2004 to August 2005. Our model included three categories of patients: frail (at least one of the following items: Activities of Daily Living scale or =3 comorbidities unrelated to the tumor according to the Charlson Index, performance status or =3 according respectively to Karnofsky and the ECOG scale, > or =1 geriatric syndrome); borderline (patients with multiple comorbidities not affecting performance status or ability in daily activities); non-frail. Applying the aforementioned criteria, we found 30 borderline, 14 frail and 109 non-frail patients. Statistical analysis showed a significant difference in mortality between frail and non-frail patients (P patients. Our model was thus able to identify patients at higher risk of death. These results confirm the importance of cancer geriatric assessment also for the clinical evaluation of oncological patients. Additional randomized studies with a larger number of patients, also in an adjuvant setting, should be performed to confirm the effectiveness of this approach.

    A framework for risk assessment due to offsite transportation of hazardous wastes is designed based on the type of event that can be triggered from an accident of a hazardous waste carrier. The objective of this study is to design a framework for computing the risk to population associated with offsite transportation of inflammable and volatile wastes. The framework is based on traditional definition of risk and is designed for conditions where accident databases are not available. The probability based variable in risk assessment framework is substituted by a composite accident index proposed in this study. The framework computes the impacts due to a volatile cloud explosion based on TNO Multi-energy model. The methodology also estimates the vulnerable population in terms of disability adjusted life years (DALY) which takes into consideration the demographic profile of the population and the degree of injury on mortality and morbidity sustained. The methodology is illustrated using a case study of a pharmaceutical industry in the Kolkata metropolitan area. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available The number of models of Decentralized Renewable Energy (DRE systems, particularly for rural electrification, is growing globally. Most approaches to assess the sustainability of these solutions beyond simple techno-economic considerations are comparative in nature, and only allow us to evaluate performance within a set of other interventions. This leaves a gap in our understanding of the conditions for a specific model to be sustainable and whether its replication is likely to succeed. The approach suggested develops a framework to evaluate the sustainability of specific models for energy access individually and proposes analytical methods to illustrate its use. It combines the multi-dimensional analysis over five sustainability dimensions and the Multi-Tier Framework (MTF to assess technical sustainability, extending MTF’s rigorous scoring methodology to the other dimensions. The scores are based on qualitative and quantitative data collected from key stakeholders, taking into account different perspectives and aims. The framework and analytical methods are exemplified using a subset of data collected in over 40 off-grid DRE systems utilizing a common community ownership and hybrid financial structure. The proposed methodology can be used to understand the sustainability conditions of a given approach to energy access and can therefore be used by practitioners and policy makers to develop strategies and guide policies to roll out effective solutions.

    This study aimed to examine the latent structure of the Chinese version of the Comprehensive Assessment of Prospective Memory (CAPM) using confirmatory factor analysis. A total of 264 healthy Chinese participants (118 men and 146 women) took part in the study and their ages ranged from 17 to 90 years. There was no gender effect upon the frequency of prospective memory (PM) forgetting but age and education were found to be correlated significantly with these frequencies in the current sample. Results of the study also showed that the model with the best fit had a tripartite structure which consisted of a general memory factor (with all items loading on it) plus a basic activities of daily living as well as an instrumental activities of daily living factor. Furthermore, this tripartite model was robust across subgroups with respect to gender, education, and age. These findings provide support for the construct validity of the original CAPM and demonstrate its utility in another culture.

    Geographic information systems (GIS) mapping technologies have potential to advance public health promotion by mapping regional differences in attributes (e.g., disease burden, environmental exposures, access to health care services) to suggest priorities for public health interventions. Training in GIS for comprehensive cancer control (CCC) has been overlooked. State CCC programs' GIS training needs were assessed by interviewing 49 state CCC directors. A majority perceived a need for GIS training, slightly more than half of state CCC programs had access to geocoded data, and the majority of programs did not require continuing education credits of their staff. CCC directors perceived judging maps and realizing their limitations as important skills and identified epidemiologists, CCC staff, public health officials, policy makers, and cancer coalition members as training audiences. They preferred in-class training sessions that last a few hours to a day. Lessons learned are shared to develop training programs with translatable GIS skills for CCC.

  9. Elements for a comprehensive assessment of natural resources: bridging environmental economics with ecological economics

    Rodriguez Romero, Paulo Cesar; Cubillos Gonzalez, Alexander

    2012-01-01

    The predominance of economic assessments regarding the value of natural resources has caused a sub-valuing of the real benefits which societies can obtain from nature. This is due to a lack of knowledge about the complexity of ecological functions, as well as a dismissal of the integrated relations of the sub-systems which make up the environment. It is therefore necessary to establish conceptual bridges between environmental sciences to fill in the gaps in economic valuation methods by recurring to diverse measuring scales, participation from the different actors involved, and a principle of precaution regarding the limits of nature. This paper explores the concepts of value and economic valuation methods from the perspectives of Environmental Economics and Ecological Economics. It then proposes an integration of valuing methodologies which take into account how complementary and complex natures value relations are. This proposal of valuing integrally ecosystem goods and services contributes to adjusting political decisions more accordingly to real environmental conditions.

    On August 24, 1992, Hurricane Andrew struck southern Florida. More than 28,000 houses, mobile homes, and apartment buildings were destroyed, and approximately 107,000 additional dwellings sustained major damage. An estimated 180,000 persons were left homeless; insured damages were estimated at $15.5 billion and total damages at more than $30 billion. During the recovery period, many private and public health-care facilities damaged or destroyed in the storm were not functional. During November 3-13, to help prioritize health needs and direct public health resources, the Dade County Public Health Unit of the Florida Department of Health and Rehabilitative Services conducted a survey to assess health needs and the availability of health-care services during the recovery phase with funds provided by the Federal Emergency Management Agency (FEMA). This report summarizes the results of the survey.

    Purpose: Our past practice for liver and pancreas SBRT consisted of free breathing (FB) with gated treatment delivery using a 30-70% phase window. We have recently adopted an assessment method leading to individualized motion management to minimize target motion. We present our results from 47 patients treated with this new approach. Methods: We perform an initial patient coaching and assessment session in our conventional simulator suite to observe the motion of the implanted fiducials with FB anterior and lateral 20-second cine acquisitions. The physician decides whether to attempt inhale or exhale breath-hold (BH). The patient is coached while observing with cine to ascertain their ability to achieve the desired BH mode for long periods as needed for treatment delivery. If the patient cannot comply, a FB approach is adopted using gating or simple ITV method (for patients without fiducials). After achieving a patient-specific motion management mode, we perform CT-simulation using the Varian RPM system to reproduce the chosen mode and record a reference session for treatment delivery. For pre-treatment imaging, the fiducials are observed under fluoro while coaching the patient. Results: Of 47 SBRT cases analyzed, 32 were liver and 15 were pancreas. The chosen techniques were: 32 exhale BH (12 with abdominal compression), 7 FB gated, 4 inhale BH, and 4 FB ITV. Maximum fiducial motion amplitude was 5 mm for the FB gated patients, and less than 5 mm for all BH patients with most able to achieve a maximum amplitude of 3 mm. Conclusion: This study showed that an individualized motion management approach can reduce the target volume and, therefore, the volume of irradiated healthy tissue from liver or pancreas SBRT. Effective coaching is essential in achieving consistent BH with 3 mm amplitude. The fluoro/cine session is helpful in establishing the right coaching approach for each patient.

    Assessing the impact of human intervention on flow regimes is important in policy making and resource management. Previous impact assessments of dam regulation on flow regimes have focused on long-term average patterns, but interannual variations, which are important characteristics to be considered, have been ignored. In this study, the entire signatures of hydrograph variations of Miyun Reservoir in northern China were described by forty flow regime metrics that incorporate magnitude, variability and frequency, duration, timing, and rate of change for flow events based on a long-term synchronous observation series of inflow and outflow. Principal component analysis and cluster analysis were used to reduce the multidimensionality of the metrics and time and to determine impact patterns and their interannual shifts. Statistically significant driving factors of impact pattern variations were identified. We found that dam regulation resulted in four main impact classes on the flow regimes and that the regulated capacity was interannually attenuated from 1973 to 2010. The impact patterns alternated between the highly regulated class with extremely decreasing flow magnitude, slight variability, and extreme intermittency and the slightly regulated class with extremely increasing flow magnitude, slight variability, and extreme intermittency from 1973 to 1987 and then stabilized in the latter class from 1988 to 2001. After 2001, the pattern gradually changed from the moderately regulated class with moderately decreasing flow magnitude, extreme variability, and extreme intermittency to the slightly regulated class with slightly decreasing flow magnitude, slight variability, and no intermittency. Decreasing precipitation and increasing drought were the primary drivers for the interannual variations of the impact patterns, and inflow variability was the most significant factor affecting the patterns, followed by flow event frequency and duration, magnitude, and timing.

    Allocation of inevitably limited financial resources for health care requires assessment of an intervention's effectiveness. Interventions likely affect quality of life (QOL) more broadly than is measurable with commonly used health-related QOL utility scales. In line with the World Health Organization's definition of health, a recent Delphi procedure showed that assessment needs to put more emphasis on mental and social dimensions. To identify the core dimensions of health-related subjective well-being (HR-SWB) for a new, more comprehensive outcome measure. We formulated items for each domain of an initial Delphi-based set of 21 domains of HR-SWB. We tested these items in a large sample (N = 1143) and used dimensionality analyses to find a smaller number of latent factors. Exploratory factor analysis suggested a five-factor model, which explained 65% of the total variance. Factors related to physical independence, positive affect, negative affect, autonomy, and personal growth. Correlations between the factors ranged from 0.19 to 0.59. A closer inspection of the factors revealed an overlap between the newly identified core dimensions of HR-SWB and the validation scales, but the dimensions of HR-SWB also seemed to reflect additional aspects. This shows that the dimensions of HR-SWB we identified go beyond the existing health-related QOL instruments. We identified a set of five key dimensions to be included in a new, comprehensive measure of HR-SWB that reliably captures these dimensions and fills in the gaps of the existent measures used in economic evaluations.

    To present current strategies for the assessment and comprehensive care of patients with hemophilia and von Willebrand's disease. Hospital care, home care, single-provider care and multidisciplinary care. Morbidity and quality of life associated with bleeding and treatment. Relevant clinical studies and reports published from 1974 to 1994 were examined. A search was conducted of own reprint files, MEDLINE, citations in the articles reviewed and references provided by colleagues. In the MEDLINE search the following terms were used singly or in combination: "hemophilia," "von Willebrand's disease," "Factor VIII," "Factor IX," "von Willebrand factor," "diagnosis," "management," "home care," "comprehensive care," "inhibitor," "AIDS," "hepatitis," "life expectancy," "complications," "practice guidelines," "consensus statement" and "controlled trial." The in-depth review included only articles written in English from North America and Europe that were relevant to human disease and to a predetermined outline. The availability of treatment products in Canada was also considered. Minimizing morbidity and maximizing functional status and quality of life were given a high value. The optimal use of treatment procedures and home care offers patients the advantages of minimized disability, improved survival and financial benefit. It is also cost effective. Potential harm, including the risk of hepatitis B, hepatitis C and HIV infection, has now been minimized through viral inactivation of plasma-derived coagulation-factor concentrates and through the use of recombinant clotting factor concentrates and other non-plasma-derived hemostatic agents. Patients with hemophilia and severe von Willebrand's disease should be followed in comprehensive care centres that offer expertise in the diagnosis, assessment and management of bleeding and complications and that can meet the educational and counselling needs of patients, family members and health care providers. Eligible patients should

    Few data is available on the nutritional status of old Chinese. The present study aimed to describe the nutritional status and clinical correlates for malnutrition risk in the older people. Cross-sectional study. Hospital- and community-based older people were recruited in the region of Chongqing, China. 558 individuals aged 60 years old or over between April 2011 and October 2012. Comprehensive geriatric assessment was performed and nutritional status was assessed by the Mini Nutritional Assessment Short Form (MNA-SF). Nutrition-associated factors were analyzed, including health status (chronic diseases, depression, cognition, function impaired), social factors (education status, marital status, the type of work before 60 years old) and life style factors (smoking, drinking, diet). The mean age was 73.1±8.0 years and 43.9% were men. Prevalence of malnutrition and risk for malnutrition were 3.2% and 19.3 %, respectively. Several factors increased poor nutrition independently including self-rated health, comorbidity, chronic obstructive pulmonary disease, gastrointestinal disease and cognitive impairment. Fish decreased the risk of poor nutrition. The prevalence was relatively low in older people of Chongqing, Southwest China. Poor nutrition was found to be increased due to the common health problems. Thus the patients with these problems should pay more attention on nutritional status. The older people should often have fish because of their nutritional benefit.

    Currently, the most advanced and well documented risk assessments for the transportation of dangerous goods by railway take into account:(i)statistics-based loss of containment frequencies, (ii) specification of potential consequences for a given release situations using event tree methodology as an organisational tool and (iii) consequence calculation models to determine a risk figure known as CCDF (Complementary Cumulative Distribution Function). Such procedures for the risk assessment (including for example decision-making on preventive measures) may offer only a limited insight into the causes and sequences leading to an accident and do not allow for any kind of predictive analysis. The present work introduces an enhanced solution, and a related software platform, which attempts to integrate loss of containment causes and consequences with system's infrastructure and its environment. The solution features:(i)the use of a detailed Master Logical Diagram, including fault/event tree analysis to determine a loss of containment frequency based on different initiating events, scenarios and specific basic data, (ii) the characterization of a resulting source term following a release situation, and (iii) the calculation of various potential impacts on the neighbouring site. Results are wrapped into a CCDF format for each selected traffic segment. The risk-related results are integrated on a software platform, structured as a decision support system using intelligent maps and a variety of GIS (Geographical Information System) data processing procedures. The introduction of the hot spot approach, allows us to focus on the most risk-relevant areas and to use information on various railway infrastructure elements (e.g. points, tunnels), are the basis of the new models employed. The software is applicable to any railway transportation system, comprising its technical infrastructure, rolling stock, human actions, regulation and management procedures. It provides the

    Full Text Available Distribution and fraction of heavy metals (Pb, Cr, Zn, and Mn in water and sediment in Liangtan River, Chongqing was analyzed using the atomic absorption spectrometry method. Pearson correlation coefficient, bioavailability index, geoaccumulation index and potential ecological risk index were introduced to classify the source and assess the environmental risk of the heavy metal. Pb, Cr, and Zn mainly existed in residual fraction and fraction bounded to Fe–Mn oxides while Mn mainly existed in the fraction bounded to carbonates and the residual fraction. Mn and Pb, Zn and Cr in the sediment were confirmed originating from, separate common sources. Igeo and $E_\\text{r}^{i}$ were both in the order of Pb > Zn > Cr > Mn. Geoaccumulation indexes demonstrated that the Liangtan River has been heavily polluted by Pb and Zn with the class of 2–4 and 2–3, independently. From viewpoint of the whole Liangtan River, the mean RI (45.1 belonged to low risk level.

    In this study, the distribution of steroid hormones, phytoestrogens, and estrogenic activity was thoroughly characterized within the anaerobic waste lagoon of a typical commercial swine sow operation. Three independent rounds of sampling were conducted in June 2009, April 2010, and February 2011. Thirty-seven analytes in lagoon slurry and sludge were assessed using LC/MS-MS, and yeast estrogen screen was used to determine estrogenic activity. Of the hormone analytes, steroidal estrogens were more abundant than androgens or progesterone, with estrone being the predominant estrogen species. Conjugated hormones were detected only at low levels. The isoflavone metabolite equol was by far the predominant phytoestrogen species, with daidzein, genistein, formononetin, and coumestrol present at lower levels. Phytoestrogens were often more abundant than steroidal estrogens, but contributed minimally towards total estrogenic activity. Analytes were significantly elevated in the solid phases of the lagoon; although low observed log KOC values suggest enhanced solubility in the aqueous phase, perhaps due to dissolved or colloidal organic carbon. The association with the solid phase, as well as recalcitrance of analytes to anaerobic degradation, results in a markedly elevated load of analytes and estrogenic activity within lagoon sludge. Overall, findings emphasize the importance of adsorption and transformation processes in governing the fate of these compounds in lagoon waste, which is ultimately used for broadcast application as a fertilizer.

    At the Community Coordinated Modeling Center (CCMC), the assessment of modeling skill using a library of model-data comparison metrics is taken to the next level by fully integrating the ability to request a series of runs with the same model parameters for a list of events. The CAMEL framework initiates and runs a series of selected, pre-defined simulation settings for participating models (e.g., WSA-ENLIL, SWMF-SC+IH for the heliosphere, SWMF-GM, OpenGGCM, LFM, GUMICS for the magnetosphere) and performs post-processing using existing tools for a host of different output parameters. The framework compares the resulting time series data with respective observational data and computes a suite of metrics such as Prediction Efficiency, Root Mean Square Error, Probability of Detection, Probability of False Detection, Heidke Skill Score for each model-data pair. The system then plots scores by event and aggregated over all events for all participating models and run settings. We are building on past experiences with model-data comparisons of magnetosphere and ionosphere model outputs in GEM2008, GEM-CEDAR CETI2010 and Operational Space Weather Model challenges (2010-2013). We can apply the framework also to solar-heliosphere as well as radiation belt models. The CAMEL framework takes advantage of model simulations described with Space Physics Archive Search and Extract (SPASE) metadata and a database backend design developed for a next-generation Run-on-Request system at the CCMC.

  2. Developing a Comprehensive Risk Assessment Framework for Geological Storage CO2

    Energy Technology Data Exchange (ETDEWEB)

    Duncan, Ian [Univ. of Texas, Austin, TX (United States)

    2014-08-31

    The operational risks for CCS projects include: risks of capturing, compressing, transporting and injecting CO₂; risks of well blowouts; risk that CO2 will leak into shallow aquifers and contaminate potable water; and risk that sequestered CO2 will leak into the atmosphere. This report examines these risks by using information on the risks associated with analogue activities such as CO2 based enhanced oil recovery (CO2-EOR), natural gas storage and acid gas disposal. We have developed a new analysis of pipeline risk based on Bayesian statistical analysis. Bayesian theory probabilities may describe states of partial knowledge, even perhaps those related to non-repeatable events. The Bayesian approach enables both utilizing existing data and at the same time having the capability to adsorb new information thus to lower uncertainty in our understanding of complex systems. Incident rates for both natural gas and CO2 pipelines have been widely used in papers and reports on risk of CO2 pipelines as proxies for the individual risk created by such pipelines. Published risk studies of CO2 pipelines suggest that the individual risk associated with CO2 pipelines is between 10-3 and 10-4, which reflects risk levels approaching those of mountain climbing, which many would find unacceptably high. This report concludes, based on a careful analysis of natural gas pipeline failures, suggests that the individual risk of CO2 pipelines is likely in the range of 10-6 to 10-7, a risk range considered in the acceptable to negligible range in most countries. If, as is commonly thought, pipelines represent the highest risk component of CCS outside of the capture plant, then this conclusion suggests that most (if not all) previous quantitative- risk assessments of components of CCS may be orders of magnitude to high.

    It is noted that dozens of hectares of Kazakhstan's land are removed from national use due to high level of ecologically permissible effect. In some regions there is treat of complete loss of lands due to technogene pollution. There are areales of toxic and radioactive industrial wastes and environmental radiation contamination zones forming in result of: activity of Semipalatinsk nuclear test site and nuclear explosions of period 1949-1961; activity of military-industrial, atomic-industrial and military-space enterprises; mining and processing of mineral resources with high content of radioactive elements; wind transfer of radionuclides and radioactive particles of both the natural and the technogene origin; radiation background of natural (In average by Republic 11-18 μR/h) landscapes. Most dangerous are consequences of tests on nuclear and space sites. Kazakhstan is single place on the Earth where nuclear strategic programs were carried out in full volume, beginning from mining and processing of uranium containing raw by producing and testing of nuclear warheads, missiles destroying and disposal of uranium and other radioactive and toxic wastes of military-industrial complex. So, there were 500 atmosphere and underground explosions in former Semipalatinsk, Kostanaj, Akmola, Aktyube, South-Kazakhstan, West-Kazakhstan, Mangistau and Atyrau oblasts. In West Kazakhstan on known nuclear sites (Azgir, Tojsogan, Central) and on Kapustin Yar fly-test complex more than 30 nuclear explosions were carried out in both the atmosphere and the underground. More than hundred military units were tested and exposed and 20 thousand of missiles were destroyed. Powerful sources of pollution are Bojkonyr spaceport and Saryshgan and Elba test sites. Authors noted, that it is necessary develop criteria of definition of payments for resources use, indexes to base taxes, pay for damages. Some problems of regional management could be solved with help this assessment mechanism

    Upper limb amputations are one of the unpleasant war injuries that armed forces are exposed to frequently. The present study aimed to assess the musculoskeletal and peripheral nervous systems in Iraq-Iran war veterans with bilateral upper extremity amputation. The study consisted of taking a history and clinical examinations including demographic data, presence and location of pain, level of amputation, passive and active ranges of movement of the joints across the upper and lower extremities and spine, manual palpation, neurological examination, blood circulation pulses and issues related to a prosthetic limb. In this study, 103 Iranian bilateral upper extremity amputees (206 amputations) from the Iran-Iraq war were evaluated, and a detailed questionnaire was also administered. The most common level of amputation was the finger or wrist level (108, 52.4 %). Based on clinical examination, we found high frequencies of limited active and passive joint range of movement across the scapula, shoulder, elbow, wrist and metacarpophalangeal, interphalangeal and thumb joints. Based on muscle strength testing, we found varying degrees of weakness across the upper limbs. Musculoskeletal disorders included epicondylitis (65, 31.6 %), rotator cuff injury (24, 11.7 %), bicipital tendonitis (69, 33.5 %), shoulder drop (42, 20.4 %) and muscle atrophy (19, 9.2 %). Peripheral nerve disorders included carpal tunnel syndrome in 13 (6.3 %) and unilateral brachial plexus injury in 1 (1 %). Fifty-three (51.5 %) were diagnosed with facet joint syndrome at the level of the cervical spine (the most frequent site). Using a prosthesis was reported by 65 (63.1 %), both left and right sides. The back was the most common site of pain (71.8 %). The high prevalence of neuro-musculoskeletal disorders among bilateral upper extremity amputees indicates that they need regular rehabilitation care.

    Surface downward longwave radiation (SDLR) is a key variable for calculating the earth's surface radiation budget. In this study, we evaluated seven widely used clear-sky parameterization methods using ground measurements collected from 71 globally distributed fluxnet sites. The Bayesian model averaging (BMA) method was also introduced to obtain a multi-model ensemble estimate. As a whole, the parameterization method of Carmona et al. (2014) performs the best, with an average BIAS, RMSE, and R 2 of - 0.11 W/m2, 20.35 W/m2, and 0.92, respectively, followed by the parameterization methods of Idso (1981), Prata (Q J R Meteorol Soc 122:1127-1151, 1996), Brunt and Sc (Q J R Meteorol Soc 58:389-420, 1932), and Brutsaert (Water Resour Res 11:742-744, 1975). The accuracy of the BMA is close to that of the parameterization method of Carmona et al. (2014) and comparable to that of the parameterization method of Idso (1981). The advantage of the BMA is that it achieves balanced results compared to the integrated single parameterization methods. To fully assess the performance of the parameterization methods, the effects of climate type, land cover, and surface elevation were also investigated. The five parameterization methods and BMA all failed over land with the tropical climate type, with high water vapor, and had poor results over forest, wetland, and ice. These methods achieved better results over desert, bare land, cropland, and grass and had acceptable accuracies for sites at different elevations, except for the parameterization method of Carmona et al. (2014) over high elevation sites. Thus, a method that can be successfully applied everywhere does not exist.

    The fractured rock region of Maryland, which includes land areas north and west of the Interstate 95 corridor, is the source of water supply for approximately 4.4 million Marylanders, or approximately 76 percent of the State's population. Whereas hundreds of thousands of residents rely on wells (both domestic and community), millions rely on surface-water sources. In this region, land use, geology, topography, water withdrawals, impoundments, and other factors affect water-flow characteristics. The unconfined groundwater systems are closely interconnected with rivers and streams, and are affected by seasonal and climatic variations. During droughts, groundwater levels drop, thereby decreasing well yields, and in some cases, wells have gone dry. Low ground-water levels contribute to reduced streamflows, which in turn, can lead to reduced habitat for aquatic life. Increased demand, over-allocation, population growth, and climate change can affect the future sustainability of water supplies in the region of Maryland underlain by fractured rock. In response to recommendations of the 2008 Advisory Committee on the Management and Protection of the State's Water Resources report, the Maryland Department of the Environment's Water Supply Program, the Maryland Geological Survey, the Maryland Department of Natural Resources, Monitoring and Non-Tidal Assessment (MANTA) Division, and the U.S. Geological Survey have developed a science plan for a comprehensive assessment that will provide new scientific information, new data analysis, and new tools for the State to better manage water resources in the fractured rock region of Maryland. The science plan lays out five goals for the comprehensive assessment: (1) develop tools for the improved management and investigation of groundwater and surface-water resources; (2) characterize factors affecting reliable yields of individual groundwater and surface-water supplies; (3) investigate impacts on nearby water withdrawal users caused

    Landsat satellite imagery has long been recognized as unique among remotely sensed data due to the combination of its extensive archive, global coverage, and relatively high spatial and temporal resolution. Since the imagery became available at no cost in 2008, the number of users registered with the U.S. Geological Survey (USGS) has increased tenfold while the number of scenes downloaded annually has increased a hundredfold. It is clear that the imagery is being used extensively, and understanding the benefits provided by this imagery can help inform decisions involving its provision. However, the value of Landsat imagery is difficult to measure for a variety of reasons, one of which stems from the fact that the imagery has characteristics of a public good and does not have a direct market price to reflect its value to society. Further, there is not a clear understanding of the full range of users of the imagery, as well as how these users are distributed across the many different end uses this data is applied to. To assess the value of Landsat imagery, we conducted a survey of users registered with USGS in early 2012. Over 11,000 current users of Landsat imagery responded to the survey. The value of the imagery was measured both qualitatively and quantitatively. To explore the qualitative value of the imagery, users were asked about the importance of the imagery to their work, their dependence on the imagery, and the impacts on their work if there was no Landsat imagery. The majority of users deemed Landsat imagery important to their work and stated they were dependent on Landsat imagery to do their work. Additionally, if Landsat imagery was no longer available, over half of the users would have to discontinue some of their work. On average, these users would discontinue half of their current work if the imagery was no longer available. The focus of this presentation will be the quantitative results of a double-bounded contingent valuation analysis which reveals

    The rapid development of multiple national geospatial datasets related to topography, hydrology, and environmental characteristics in the past decade have provided new opportunities for the refinement of hydropower resource potential from undeveloped stream-reaches. Through 2011 to 2013, the Oak Ridge National Laboratory (ORNL) was tasked by the Department of Energy (DOE) Water Power Program to evaluate the new stream-reach development (NSD) resource potential for more than 3 million US streams. A methodology was designed that contains three main components: (1) identification of stream-reaches with high energy density, (2) topographical analysis of stream-reaches to estimate inundated surface area and reservoir storage, and (3) environmental attribution to spatially join information related to the natural ecological systems, social and cultural settings, policies, management, and legal constraints to stream-reaches of energy potential. An initial report on methodology (Hadjerioua et al., 2013) was later reviewed and revised based on the comments gathered from two peer review workshops. After implementing the assessment across the entire United States, major findings were summarized in this final report. The estimated NSD capacity and generation, including both higher-energy-density (>1 MW per reach) and lower-energy-density (<1 MW per reach) stream-reaches is 84.7 GW, around the same size as the existing US conventional hydropower nameplate capacity (79.5 GW; NHAAP, 2013). In terms of energy, the total undeveloped NSD generation is estimated to be 460 TWh/year, around 169% of average 2002 2011 net annual generation from existing conventional hydropower plants (272 TWh/year; EIA, 2013). Given the run-of-river assumption, NSD stream-reaches have higher capacity factors (53 71%), especially compared with conventional larger-storage peaking-operation projects that usually have capacity factors of around 30%. The highest potential is identified in the Pacific Northwest

    Introduction. A comprehensive geriatric assessment systematically collects information on geriatric conditions and is propagated in oncology as a useful tool when assessing older cancer patients. Objectives. The objectives were: (a) to study the prevalence of geriatric conditions in cancer patients aged ≥65 years, acutely admitted to a general medicine ward; (b) to determine functional decline and mortality within 12 months after admission; and (c) to assess which geriatric conditions and cancer-related variables are associated with 12-month mortality. Methods. This was an observational cohort study of 292 cancer patients aged ≥65 years, acutely admitted to the general medicine and oncology wards of two university hospitals and one secondary teaching hospital. Baseline assessments included patient characteristics, reason for admission, comorbidity, and geriatric conditions. Follow-up at 3 and 12 months was aimed at functional decline (loss of one or more activities of daily living [ADL]) and mortality. Results. The median patient age was 74.9 years, and 95% lived independently; 126 patients (43%) had metastatic disease. A high prevalence of geriatric conditions was found for instrumental ADL impairment (78%), depressive symptoms (65%), pain (65%), impaired mobility (48%), malnutrition (46%), and ADL impairment (38%). Functional decline was observed in 8% and 33% of patients at 3 and 12 months, respectively. Mortality rates were 38% at 3 months and 64% at 12 months. Mortality was associated with cancer-related factors only. Conclusion. In these acutely hospitalized older cancer patients, mortality was only associated with cancer-related factors. The prevalence of geriatric conditions in this population was high. Future research is needed to elucidate if addressing these conditions can improve quality of life. PMID:21914699

    To assess the efficacy of comprehensive geriatric assessment (CGA) in prevention of delirium after hip fracture. Systematic review and metaanalysis. Ward based models on geriatrics wards and visiting team based models on orthopaedics wards were included. Four trials (three European, one U.S.; 973 participants) were identified. Two assessed ward-based, and two assessed team-based interventions. MEDLINE, EMBASE, CINAHL and PsycINFO databases; Clinicaltrials.gov; and the Central Register of Controlled Trials were searched. Reference lists from full-text articles were reviewed. Incidence of delirium was the primary outcome. Length of stay, delirium severity, institutionalization, long-term cognition and mortality were predefined secondary outcomes. Duration of delirium was included as a post hoc outcome. There was a significant reduction in delirium overall (relative risk (RR) = 0.81, 95% confidence interval (CI) = 0.69-0.94) in the intervention group. Post hoc subgroup analysis found this effect to be preserved in the team-based intervention group (RR = 0.77, 95% CI = 0.61-0.98) but not the ward-based group. No significant effect was observed on any secondary outcome. There was a reduction in the incidence of delirium after hip fracture with CGA. This is in keeping with results of non-randomized controlled trials and trials in other populations. Team-based interventions appeared superior in contrast to the Ellis CGA paper, but it is likely that heterogeneity in interventions and population studied affected this. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Studies on gene expression in response to therapy have led to the discovery of pharmacogenomics biomarkers and advances in precision medicine. Whole transcriptome sequencing (RNA-seq) is an emerging tool for profiling gene expression and has received wide adoption in the biomedical research community. However, its value in regulatory decision making requires rigorous assessment and consensus between various stakeholders, including the research community, regulatory agencies, and industry. The FDA-led SEquencing Quality Control (SEQC) consortium has made considerable progress in this direction, and is the subject of this review. Specifically, three RNA-seq platforms (Illumina HiSeq, Life Technologies SOLiD, and Roche 454) were extensively evaluated at multiple sites to assess cross-site and cross-platform reproducibility. The results demonstrated that relative gene expression measurements were consistently comparable across labs and platforms, but not so for the measurement of absolute expression levels. As part of the quality evaluation several studies were included to evaluate the utility of RNA-seq in clinical settings and safety assessment. The neuroblastoma study profiled tumor samples from 498 pediatric neuroblastoma patients by both microarray and RNA-seq. RNA-seq offers more utilities than microarray in determining the transcriptomic characteristics of cancer. However, RNA-seq and microarray-based models were comparable in clinical endpoint prediction, even when including additional features unique to RNA-seq beyond gene expression. The toxicogenomics study compared microarray and RNA-seq profiles of the liver samples from rats exposed to 27 different chemicals representing multiple toxicity modes of action. Cross-platform concordance was dependent on chemical treatment and transcript abundance. Though both RNA-seq and microarray are suitable for developing gene expression based predictive models with comparable prediction performance, RNA-seq offers

    Spatial concentrations and chemical fractions of heavy metals (Cr, Cu, Pb, Zn and Cd) in 16 sampling sites from the Honghu Lake were investigated using an atomic absorption spectrophotometer and optimized BCR (the European Community Bureau of Reference) three-stage extraction procedure. Compared with the corresponding probable effect levels (PELs), adverse biological effects of the studied five sediment metals decreased in the sequence of Cr > Cu > Zn > Pb > Cd. Geo-accumulation index ( I geo ) values for Cr, Cu, Pb and Zn in each sampling site were at un-contamination level, while the values for Cd varied from un-contamination level to moderate contamination level. Spatially, the enrichment degree of Cd in lower part of the South Lake, the west part of the North Lake and the outlet were higher than the other parts of Honghu Lake. For metal chemical fractions, the proportions of the acid-extractable fraction of five metal contents were in the descending order: Cd, Cu, Zn, Pb and Cr. Cd had the highest bioaccessibility. Being the above indexes focused always on heavy metals' total content or chemical fraction in deterministic assessment system, which may confuse decision makers, the fuzzy comprehensive risk assessment method was established based on PEI (Potential ecological risk index), RAC (Risk assessment code) and fuzzy theory. Average comprehensive risks of heavy metals in sediments revealed the following orders: Cd (considerable risk) > Cu (moderate risk) > Zn (low risk) > Pb > Cr. Thus, Cd and Cu were determined as the pollutants of most concern. The central part of South Honghu Lake (S4, S5, S6, S9, S12 and S14), east part of the North Honghu Lake (S1) and outlet of outlet of the Honghu Lake (S10) were recommended as the priority control areas. Specifically, it is necessary to pay more attention to S1, S4, S5, S6, S9 and S16 when decision making for their calculated membership values (probabilities) of adjacent risk levels quite close.

    In the paper the methodological problems of establishing a general class of working conditions on the results of certification of workplaces are analyzed There is proposed the use of an additional parameter - the index of harm, characterizing the degree of correspondence of the general level of harmful occupational factors to applicable health standards with taking into account the nonequivalence of their display. The recommendations for the use of hazard index as the main criterion for a priori evaluation ofthe category ofsuspected occupational risk and the tool to establish by the correlation methods cause-and-effect relations between indices of health status and the impact ofoccupational factors are presented. As exemplified by real working conditions the possibilities of the use the index of harm as an indicator describing the hazard probability are considered with comprehensive assessment of occupational risk of health problems on the basis of the matrix method with the use of the table of vectors and nomograms "probability of harm - the severity of the consequences". The use of index of harm will permit to increase the objectivity of the assessment and the efficacy of management of occupational hazards in the workplaces.

    We present new observations of the three nearest early-type galaxy (ETG) strong lenses discovered in the SINFONI Nearby Elliptical Lens Locator Survey (SNELLS). Based on their lensing masses, these ETGs were inferred to have a stellar initial mass function (IMF) consistent with that of the Milky Way, not the bottom-heavy IMF that has been reported as typical for high- σ ETGs based on lensing, dynamical, and stellar population synthesis techniques. We use these unique systems to test the consistency of IMF estimates derived from different methods. We first estimate the stellar M {sub *}/ L using lensing and stellar dynamics. We then fit high-quality optical spectra of the lenses using an updated version of the stellar population synthesis models developed by Conroy and van Dokkum. When examined individually, we find good agreement among these methods for one galaxy. The other two galaxies show 2–3 σ tension with lensing estimates, depending on the dark matter contribution, when considering IMFs that extend to 0.08 M {sub ⊙}. Allowing a variable low-mass cutoff or a nonparametric form of the IMF reduces the tension among the IMF estimates to <2 σ . There is moderate evidence for a reduced number of low-mass stars in the SNELLS spectra, but no such evidence in a composite spectrum of matched- σ ETGs drawn from the SDSS. Such variation in the form of the IMF at low stellar masses ( m ≲ 0.3 M {sub ⊙}), if present, could reconcile lensing/dynamical and spectroscopic IMF estimates for the SNELLS lenses and account for their lighter M {sub *}/ L relative to the mean matched- σ ETG. We provide the spectra used in this study to facilitate future comparisons.

    Accurate documentation of disease severity is a prerequisite for clinical research and the practice of evidence-based medicine. The quantification of skin diseases such as psoriasis currently relies heavily on clinical scores. Although these clinical scoring methods are well established and very useful in quantifying disease severity, they require an extensive clinical experience and carry a risk of subjectivity. We explore the opportunity to use in vivo near-infrared (NIR) spectra as an objective and noninvasive method for local disease severity assessment in 31 psoriasis patients in whom selected plaques were scored clinically. A partial least squares (PLS) regression model was used to analyze and predict the severity scores on the NIR spectra of psoriatic and uninvolved skin. The correlation between predicted and clinically assigned scores was R=0.94 (RMSE=0.96), suggesting that in vivo NIR provides accurate clinical quantification of psoriatic plaques. Hence, NIR may be a practical solution to clinical severity assessment of psoriasis, providing a continuous, linear, numerical value of severity.

    Disability affects older adults' quality of life. This study aimed to examine the socio-demographic characteristics of disability in older adults in China. Data was obtained from the China Comprehensive Geriatric Assessment Study (CCGAS). The sample comprised 6864 people aged 60 years and above from seven provinces in China. A door-to-door survey was conducted by formally trained interviewers using a unified questionnaire. Disability was assessed with physical health assessment comprising activities of daily living (ADL), and independent activities of daily living (IADL). For the purpose of this study, we analyzed only disability and some socio-demographic dimensions. The rates were standardized based on China's Sixth National Census population distribution. The disability rate in older adults was 7.0%. The disability rate was significantly higher in women than men, significantly higher in rural areas than urban areas, and higher in northern China than southern China. Urban disability rates ranged from 5.7% to 1.2%. The differences were statistically significant, with Beijing having the highest and Shanghai the lowest disability rates. Disability increased with age. In China, the disability rate in older adults is 7.0%, and increases with age. The disability rate is significantly higher in women, rural area, and northern China. This is the first study to report the epidemiology of disability in older adults in China in recent years and indicates the need for further epidemiological data on disability in China to facilitate long-term care and care policy formulation.

Case 1 had visited the ED twice/month due to chest discomfort. Her ED visits were significantly reduced to 0.2 visits/month following CGA-based MDT care. Case 2 had failed back surgery syndrome and bipolar disorder. His ED visit was reduced from 2.8 visits to 0.8 visits/month following CGA-based MDT intervention. Case 3 had chronic obstructive pulmonary disease, heart failure, and urinary incontinence, with a urinary catheter in place. He made 31 ED visits (5.1 visits/month before his lung cancer and depression were discovered by CGA. He died 2 months later. Case 4 made 27 ED visits (2.7 visits/month due to dizziness. His problems of early dementia and neglect were identified by CGA, and he visited the ED only once following MDT intervention. In conclusion, CGA-based MDT intervention successfully reduced ED visits among these EDFUs, but further investigation is needed to evaluate the effectiveness of geriatric services in the ED.

    There have been few evaluations of the quality of computerized decision support tools in medical oncology despite their widespread use in clinical practice. In this article, we provide an in-depth quality assessment of eviQ, an Australian web-based protocol system. We used the Appraisal of Guidelines for Research and Evaluation (AGREE-II) instrument to examine the quality of eviQ chemotherapy protocols across six domains: scope and purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability, editorial independence and overall quality rating. Domain scores were categorized as high quality (scores of >70%), moderate quality (30-70%), and low quality (development process and the rigor with which protocols were developed were of moderate quality (scores of 34-37%) and the management of editorial independence and conflict of interest issues were rated in the low quality range (22%). Our evaluation demonstrated the eviQ protocol system is generally of high quality. However, we identified a number of areas in which eviQ could improve either its development processes or the means by which these processes are communicated to end-users. This research represents the first comprehensive evaluation of oncology protocols and paves the way for continued quality assurance research to ensure that these tools meet their objective of facilitating evidence-based medicine, standardizing treatment and, ultimately, improving patient outcomes. © 2011 Blackwell Publishing Asia Pty Ltd.

    Combining wastewater treatment and biofuel production is considered the cost-effective way for better waste remediation and lowering the environmental impact for biofuel production. In this study, an innovative integrated system incorporating sludge, scum and centrate treatment and biofuel production was developed. A comprehensive techno-economic analysis was conducted to evaluate the technology and economic feasibility of the integrated system with the consideration of biofuel production, wastewater treatment improvement, tax credits, carbon credit, and coproducts utilization. Benefited from the integrated system that the intermediate byproducts can be used in between the sub-systems, such as the glycerol generated from the scum-to-biodiesel production can be used as an organic carbon for the centrate-to-algae production, the estimated breakeven selling price of the bio-oil ($1.85/gallon) is very close to the 5-year averaged crude oil price. The assessment result showed the payback period and the IRRs of the integrated system are superior in comparison with others. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The currently used instruments which measure the psychosocial work environment have been criticized. We analyzed the association between work stressors and cardiovascular disease, using the Maastricht Cohort Study Work Stressor Score (MCS-WSS), a comprehensive measure which has been associated with work strain. At baseline 11,489 employees of the Maastricht Cohort Study were participating. This prospective cohort study started in 1998 in the Netherlands and includes a heterogeneous population of employees. The psychosocial work environment, cardiovascular risk factors and the occurrence of cardiovascular disease were measured with questionnaires at various time points during follow-up, the last follow-up was in 2008. For a subsample of employees, CVD extracted from medical records was available. The MCS-WSS consists of items from emotional demands, psychological demands, role clarity, career possibilities, working overtime, job insecurity, cognitive demands, skills discretion and decision authority. Each item has its own contribution in inducing work strain, represented by its own weighting factor. The association between a high exposure to work stressors at baseline and cardiovascular morbidity was assessed with Cox regression analyses. Analyses were adjusted for age, gender, educational level, smoking, body mass index, alcohol consumption and leisure physical activity. During a median follow-up of 49 months, 309 employees developed incident cardiovascular disease. Overall, no significant associations were found between a high exposure to work stressors at baseline and cardiovascular morbidity. The results of this study indicate that high exposure to work stressors has no considerable impact on cardiovascular disease.

  6. A comparison of the responses to three comprehension and three production tasks assessing the morpho-syntactic abilities of Afrikaans-speaking preschoolers

    Full Text Available The lack of standardised assessment instruments for assessing the morpho-syntactic abilities of Afrikaans-speaking children often leads to the use of informal assessment tools and/or spontaneous language samples. The question that this paper addresses is how best to assess these morpho-syntactic abilities when using nonstandardised assessment instruments of this kind. The general aim of the present study was to answer this question. Eight typically developing, monolingual children (one boy and one girl of 3, 4, 5, and 6 years from monolingual Afrikaans-speaking homes participated. Tasks were administered to assess comprehension and production of grammatical features related to number, person, case, and tense, as well as questions forms, binding relations and passive constructions. The comprehension tasks entailed picture selection, judging the (incorrectness of utterances produced by the researcher, and question answering, whereas the production tasks consisted of sentence completion, question asking and a language sample. A specific aim of the study was to determine which method(s rendered the highest number of (i correct responses and (ii usable responses (i.e., responses strictly related to the aspect under assessment by these typically developing participants. The results indicate that picture selection elicited the highest number of both correct and usable responses in the comprehension tasks. The production task that provided the highest number of both correct and usable responses was language sample elicitation. This suggests that these tasks should receive precedence when assessing the morpho-syntactic abilities of Afrikaans-speaking preschool children.

    In clinical practice, a variety of diagnostic tests are available to assess a child's comprehension of spoken language. However, none of these tests have been designed specifically for use with children who have severe motor impairments and who experience severe difficulty when using speech to communicate. This article describes the process of investigating the reliability and validity of the Computer-Based Instrument for Low Motor Language Testing (C-BiLLT), which was specifically developed to assess spoken Dutch language comprehension in children with cerebral palsy and complex communication needs. The study included 806 children with typical development, and 87 nonspeaking children with cerebral palsy and complex communication needs, and was designed to provide information on the psychometric qualities of the C-BiLLT. The potential utility of the C-BiLLT as a measure of spoken Dutch language comprehension abilities for children with cerebral palsy and complex communication needs is discussed.

    The aim of this work was to reach a national consensus in Spain regarding the Comprehensive Geriatric Assessment (CGA) domains in older oncological patients and the CGA scales to be used as a foundation for widespread use. The Delphi method was implemented to attain consensus. Representatives of the panel were chosen from among the members of the Oncogeriatric Working Group of the Spanish Society of Medical Oncology (SEOM). Consensus was defined as ≥66.7% coincidence in responses and by the stability of said coincidence (changes ≤15% between rounds). The study was conducted between July and December 2016. Of the 17 people invited to participate, 16 agreed. The panel concluded by consensus that the following domains should be included in the CGA:(and the scales to evaluate them): functional (Barthel Index, Lawton-Brody scale, gait speed), cognitive (Pfeiffer questionnaire), nutritional (Mini Nutritional Assessment - MNA), psychological/mood (Yesavage scale), social-familial (Gijon scale), comorbidity (Charlson index), medications, and geriatric syndromes (urinary and/or fecal incontinence, low auditory and/or visual acuity, presence of falls, pressure sores, insomnia, and abuse). Also by consensus, the CGA should be administered to older patients with cancer for whom there is a subsequent therapeutic intent and who scored positive on a previous frailty-screening questionnaire. After 3 rounds, consensus was reached regarding CGA domains to be used in older patients with cancer, the scales to be administered for each of these domains, as well as the timeline to be followed during consultation.

    As efforts to develop new applications of engineered nanoscale materials (ENMs) continue to grow, so too has interest in the environmental, health, and safety (EHS) implications of these materials. However, thorough evaluation and interpretation of such implications could require substantial resources (e.g., estimated as >$120 million per year in federal funding 2013-2017). A structured, strategic approach for transparently planning research would support improved linkages between ENM research and risk assessments, and thereby enhance the utility of financial and other resources for EHS studies of ENMs. For this reason, we applied Comprehensive Environmental Assessment (CEA) as an approach to provide transparent input into research planning for 2 types of ENMs: nanoscale titanium dioxide and nanoscale silver. For each of these CEA applications, we employed a collective judgment method known as Nominal Group Technique (NGT) in 2 workshops sponsored by the US Environmental Protection Agency (USEPA). The objective of this paper is to present the outcomes of these CEA applications in the context of how our methodology can inform future efforts to identify collective goals in science (e.g., research priorities) through structured decision support approaches. Outcomes include clear lists of research priorities for each ENM developed through transparently engaging stakeholders having diverse technical and sector perspectives. In addition, we identified several procedural aspects that could be refined, including emphasizing breakout group interactions, identifying broad information priorities before more detailed research questions, and using rating rather than ranking prioritization methods. Beyond the research directions identified for specific ENMs, lessons learned about engaging stakeholders in research planning are expected to inform future research planning efforts for ENMs and other emerging materials across the scientific community. © 2014 SETAC.

    The Safety Pharmacology Society (SPS) has conducted a survey of its membership to identify industry practices related to testing considered in the Comprehensive In vitro Proarrhythmia Assay (CiPA). Survey topics included nonclinical approaches to address proarrhythmia issues, conduct of in silico studies, in vitro ion channel testing methods used, drugs used as positive controls during the conduct of cardiac ion channel studies, types of arrhythmias observed in non-clinical studies and use of the anticipated CiPA ion channel assay. In silico studies were used to evaluate effects on ventricular action potentials by only 15% of responders. In vitro assays were used mostly to assess QT prolongation (95%), cardiac Ca 2+ and Na + channel blockade (82%) and QT shortening or QRS prolongation (53%). For de-risking of candidate drugs for proarrhythmia, those assays most relevant to CiPA including cell lines stably expressing ion channels used to determine potency of drug block were most frequently used (89%) and human stem cell-derived or induced pluripotent stem cell cardiomyocytes (46%). Those in vivo assays related to general proarrhythmia derisking include ECG recording using implanted telemetry technology (88%), jacketed external telemetry (62%) and anesthetized animal models (53%). While the CiPA initiative was supported by 92% of responders, there may be some disconnect between current practice and future expectations, as explained. Proarrhythmia liability assessment in drug development presently includes study types consistent with CiPA. It is anticipated that CiPA will develop into a workable solution to the concern that proarrhythmia liability testing remains suboptimal. Copyright © 2017 The Authors. Published by Elsevier Inc.

    Objectives. We comprehensively assessed health care utilization in a population-based sample of homeless adults and matched controls under a universal health insurance system. Methods. We assessed health care utilization by 1165 homeless single men and women and adults in families and their age- and gender-matched low-income controls in Toronto, Ontario, from 2005 to 2009, using repeated-measures general linear models to calculate risk ratios and 95% confidence intervals (CIs). Results. Homeless participants had mean rates of 9.1 ambulatory care encounters (maximum = 141.1), 2.0 emergency department (ED) encounters (maximum = 104.9), 0.2 medical–surgical hospitalizations (maximum = 14.9), and 0.1 psychiatric hospitalizations per person-year (maximum = 4.8). Rate ratios for homeless participants compared with matched controls were 1.76 (95% CI = 1.58, 1.96) for ambulatory care encounters, 8.48 (95% CI = 6.72, 10.70) for ED encounters, 4.22 (95% CI = 2.99, 5.94) for medical–surgical hospitalizations, and 9.27 (95% CI = 4.42, 19.43) for psychiatric hospitalizations. Conclusions. In a universal health insurance system, homeless people had substantially higher rates of ED and hospital use than general population controls; these rates were largely driven by a subset of homeless persons with extremely high-intensity usage of health services.

    Arsenic (As), particularly of its inorganic form (iAs) is highly toxic, and its presence in food composites is a matter of concern for the public health safety, specifically in Bangladesh which is regarded as the most arsenic affected country throughout the world. This study was carried out to investigate the levels of As in the composite samples of commonly consumed foodstuffs collected from 30 different agro-ecological zones for the first time in Bangladesh. Most of the individual food composites contain a considerable amount of As which was, as a whole, in the range of 0.077–1.5 mg/kg fw which was lower than those reported from Spain, EU, France, Korea, whereas higher than those of Mexico, Chile, Japan, Cambodia, Hong Kong, Serbia, respectively. Cereals, vegetables, milk, and fish contribute about 90% to the daily intake of inorganic arsenic. Human health risk of dietary iAs was assessed separately for both the rural and urban adults. The estimated daily dietary intakes (EDI) of iAs for the exposed rural (3.5) and urban residents (3.2 μg/kg-BW/day) clearly exceeded the previous provisional tolerable daily intake (PTDI) value of 2.1 μg/kg-BW/day, recommended by the World Health Organization (WHO). From the health point of view, this study concluded that both the rural and urban residents of Bangladesh are exposed to carcinogenic and non-carcinogenic risks who consume As-contaminated water and foodstuffs. - Highlights: • A comprehensive health risk assessment from dietary arsenic exposure was evaluated. • Sample collected from 30 agro-ecological zones for the first time in Bangladesh. • Rural and urban adults are consuming more arsenic through food than the safe limit. • Cereals, vegetables, milk, and fish contribute about 90% to EDI of inorganic As. • Inhabitants are exposed chronically to arsenic induced risks.

    Frailty is closely linked to health results. Frailty indexes (FI) and the Comprehensive Geriatric Assessment (CGA) are multidimensional tools. FI serve to quantitatively measure frailty levels. They have shown to have an excellent correlation with mortality. However, they are infrequently used in clinical practice. Given the need for new, more concise, and pragmatic FI, a new FI is proposed based on a CGA (Frail-VIG Index). A prospective, observational, longitudinal study was conducted, with cohort follow up at 12 months or death. Participants were patients admitted in the Geriatric Unit of the University Hospital of Vic (Barcelona, Spain) during 2014. Contrast of hypothesis log-rank for survival curves according to Frail-VIG index, and analysis of ROC curves were performed to assess prognostic capacity. A total of 590 patients were included (mean age=86.39). Mortality rate at 12 months was 46.4%. The comparative analysis showed statistically significant differences (P<.05) for almost all variables included in the Frail-VIG index. Survival curves also show significant differences (X 2 =445, P<.001) for the different Frail-VIG index scores. The area under the ROC curve at 12 months was 0.9 (0.88-0.92). An administration time of the Index is estimated at less than 10minutes. Results endorse the Frail-VIG index as a simple (as for contents), rapid (for administration time) tool, with discriminative (for situational diagnosis) and predictive capacity (high correlation with mortality).

    A catalog has been prepared which contains information for: (1) world-wide, ground-motion accelerograms, (2) the accelerograph sites where these records were obtained, and (3) the seismological parameters of the causative earthquakes. The catalog is limited to data for those accelerograms which have been digitized and published. In addition, the quality and completeness of these data are assessed. This catalog is unique because it is the only publication which contains comprehensive information on the recording conditions of all known digitized accelerograms. However, information for many accelerograms is missing. Although some literature may have been overlooked, most of the missing data has not been published. Nevertheless, the catalog provides a convenient reference and useful tool for earthquake engineering research and applications.

    Full Text Available The aim of this study was to develop and validate an electronic questionnaire, the Electronic Maternal Health Survey (EMat Health Survey, related to women’s knowledge and perceptions of the current gestational weight gain guidelines (GWG, as well as pregnancy-related health behaviours. Constructs addressed within the questionnaire include self-efficacy, locus of control, perceived barriers, and facilitators of physical activity and diet, outcome expectations, social environment and health practices. Content validity was examined using an expert panel (n = 7 and pilot testing items in a small sample (n = 5 of pregnant women and recent mothers (target population. Test re-test reliability was assessed among a sample (n = 71 of the target population. Reliability scores were calculated for all constructs (r and intra-class correlation coefficients (ICC, those with a score of >0.5 were considered acceptable. The content validity of the questionnaire reflects the degree to which all relevant components of excessive GWG risk in women are included. Strong test-retest reliability was found in the current study, indicating that responses to the questionnaire were reliable in this population. The EMat Health Survey adds to the growing body of literature on maternal health and gestational weight gain by providing the first comprehensive questionnaire that can be self-administered and remotely accessed. The questionnaire can be completed in 15–25 min and collects useful data on various social determinants of health and GWG as well as associated health behaviours. This online tool may assist researchers by providing them with a platform to collect useful information in developing and tailoring interventions to better support women in achieving recommended weight gain targets in pregnancy.

    In the drought-prone Upper Blue Nile River (UBNR) basin of Ethiopia, soil erosion by water results in significant consequences that also affect downstream countries. However, there have been limited comprehensive studies of this and other basins with diverse agroecologies. We analyzed the variability of gross soil loss and sediment yield rates under present and expected future conditions using a newly devised methodological framework. The results showed that the basin generates an average soil loss rate of 27.5tha -1 yr -1 and a gross soil loss of ca. 473Mtyr -1 , of which, at least 10% comes from gully erosion and 26.7% leaves Ethiopia. In a factor analysis, variation in agroecology (average factor score=1.32) and slope (1.28) were the two factors most responsible for this high spatial variability. About 39% of the basin area is experiencing severe to very severe (>30tha -1 yr -1 ) soil erosion risk, which is strongly linked to population density. Severe or very severe soil erosion affects the largest proportion of land in three subbasins of the UBNR basin: Blue Nile 4 (53.9%), Blue Nile 3 (45.1%), and Jema Shet (42.5%). If appropriate soil and water conservation practices targeted ca. 77.3% of the area with moderate to severe erosion (>15tha -1 yr -1 ), the total soil loss from the basin could be reduced by ca. 52%. Our methodological framework identified the potential risk for soil erosion in large-scale zones, and with a more sophisticated model and input data of higher spatial and temporal resolution, results could be specified locally within these risk zones. Accurate assessment of soil erosion in the UBNR basin would support sustainable use of the basin's land resources and possibly open up prospects for cooperation in the Eastern Nile region.

Nodes, or hubs, showing alterations common to more than one RSN were mostly localized within the prefrontal cortex and the mesial-temporal cortex. The cerebellum showed a unique behavior where voxels of decreased gFC were only found in AD while a significant gFC increase was only found in MCI. The gFC alterations showed strong correlations (p< 0.001 with psychological scores, in particular MMSE and attention/memory tasks. In conclusion, this analysis revealed that the DMN was affected by remarkable FC increases, that FC alterations extended over several RSNs, that derangement of functional relationships between multiple areas occurred already in the early stages of dementia. These results warrant future work to verify whether these represent compensatory mechanisms that exploit a pre-existing neural reserve through plasticity, which evolve in a state of lack of connectivity between different networks with the worsening of the pathology.

    The aim of this study was to evaluate the value of comprehensive renal ultrasound (US), i.e., combining greyscale US and amplitude-coded color Doppler sonography (aCDS), for assessment of urinary tract infection (UTI) in infants and children, compared to (1) {sup 99m}Tc DMSA scintigraphy and (2) final diagnosis. Two hundred eighty-seven children with UTI underwent renal comprehensive US and DMSA scintigraphy. The results were compared with regard to their reliability to diagnose renal involvement, using (1) DMSA scintigraphy and (2) final diagnosis as the gold standard. Sixty-seven children clinically had renal involvement. Sensitivity increased from 84.1% using only aCDS to 92.1% for the combined US approach, using DMSA scintigraphy as the reference standard. When correlated with the final diagnosis, sensitivity for DMSA scintigraphy was 92.5%; sensitivity for comprehensive US was 94.0%. Our data demonstrate an increasing sensitivity using the combination of renal greyscale US supplemented by aCDS for differentiation of upper from lower UTI. Sensitivity for DMSA and comprehensive US was similar for both methods compared to the final diagnosis. Comprehensive US should gain a more important role in the imaging algorithm of children with acute UTI, thereby reducing the radiation burden. (orig.)

  4. Assessing the Determinants of Renewable Electricity Acceptance Integrating Meta-Analysis Regression and a Local Comprehensive Survey

    Full Text Available In dealing with renewable electricity (RE, individuals are involved both as end-consumers on the demand side and as stakeholders (citizens in the local production process on the supply side. Empirical evidence shows that in many countries, consumers are willing to pay a significant amount to facilitate adoption of RE. By contrast, environmental externalities are often the cause of strong opposition to RE adoption if local communities are involved as stakeholders in wind, solar or biomass investment projects. Looking at the literature on willingness to pay and on willingness to accept, we have investigated RE acceptance mechanisms. First, we have used the meta-analysis to assess the major determinants of RE acceptance on both demand and supply sides. Meta-analysis has provided some insights useful for managing field research on an onshore wind farm enlargement project located in the Umbria region. Meta-analysis and survey results confirm that the local community plays a central role in local RE acceptance. Furthermore, people who have previous experience with windmills require less compensation, or are willing to pay more, for RE development. Results suggest that these attributes should be included in future research to improve understanding of determinants of RE acceptance.

    Drug-induced cardiotoxicity is a potentially severe side effect that can adversely affect myocardial contractility through structural or electrophysiological changes in cardiomyocytes. Human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) are a promising human cardiac in vitro model system to assess both proarrhythmic and non-proarrhythmic cardiotoxicity of new drug candidates. The scalable differentiation of hiPSCs into cardiomyocytes provides a renewable cell source that overcomes species differences present in current animal models of drug toxicity testing. The Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative represents a paradigm shift for proarrhythmic risk assessment, and hiPSC-CMs are an integral component of that paradigm. The recent advancements in hiPSC-CMs will not only impact safety decisions for possible drug-induced proarrhythmia, but should also facilitate risk assessment for non-proarrhythmic cardiotoxicity, where current non-clinical approaches are limited in detecting this risk before initiation of clinical trials. Importantly, emerging evidence strongly suggests that the use of hiPSC-CMs with cardiac physiological relevant measurements in vitro improves the detection of structural cardiotoxicity. Here we review high-throughput drug screening using the hiPSC-CM model as an experimentally feasible approach to assess potential contractile and structural cardiotoxicity in early phase drug development. We also suggest that the assessment of structural cardiotoxicity can be added to electrophysiological tests in the same platform to complement the Comprehensive in vitro Proarrhythmia Assay for regulatory use. Ideally, application of these novel tools in early drug development will allow for more reliable risk assessment and lead to more informed regulatory decisions in making safe and effective drugs available to the public.

    Transgenic Tg2576 mice overexpressing human amyloid precursor protein (hAPP) are a widely used Alzheimer’s disease (AD) mouse model to evaluate treatment effects on amyloid beta (Aβ) pathology and cognition. Tg2576 mice on a B6;SJL background strain carry a recessive rd1 mutation that leads to early retinal degeneration and visual impairment in homozygous carriers. This can impair performance in behavioral tests that rely on visual cues, and thus, affect study results. Therefore, B6;SJL/Tg2576 mice were systematically backcrossed with 129S6/SvEvTac mice resulting in 129S6/Tg2576 mice that lack the rd1 mutation. 129S6/Tg2576 mice do not develop retinal degeneration but still show Aβ accumulation in the brain that is comparable to the original B6;SJL/Tg2576 mouse. However, comprehensive studies on cognitive decline in 129S6/Tg2576 mice are limited. In this study, we used two dementia mouse models on a 129S6 background—scopolamine-treated 129S6/SvEvTac mice (3–5 month-old) and transgenic 129S6/Tg2576 mice (11–13 month-old)–to establish a behavioral test battery for assessing learning and memory. The test battery consisted of five tests to evaluate different aspects of cognitive impairment: a Y-Maze forced alternation task, a novel object recognition test, the Morris water maze, the radial arm water maze, and a Y-maze spontaneous alternation task. We first established this behavioral test battery with the scopolamine-induced dementia model using 129S6/SvEvTac mice and then evaluated 129S6/Tg2576 mice using the same testing protocol. Both models showed distinctive patterns of cognitive impairment. Together, the non-invasive behavioral test battery presented here allows detecting cognitive impairment in scopolamine-treated 129S6/SvEvTac mice and in transgenic 129S6/Tg2576 mice. Due to the modular nature of this test battery, more behavioral tests, e.g. invasive assays to gain additional cognitive information, can easily be added. PMID:26808326

    The aim of this study was to investigate whether the acute care of frail elderly patients in a comprehensive geriatric assessment (CGA) unit is superior to the care in a conventional acute medical care unit. This is a clinical, prospective, randomized, controlled, one-center intervention study. This study was conducted in a large county hospital in western Sweden. The study included 408 frail elderly patients, aged ≥75 years, in need of acute in-hospital treatment. The patients were allocated to the intervention group (n=206) or control group (n=202). Mean age of the patients was 85.7 years, and 56% were female. This organizational form of care is characterized by a structured, systematic interdisciplinary CGA-based care at an acute elderly care unit. The primary outcome was the change in health-related quality of life (HRQoL) 3 months after discharge from hospital, measured by the Health Utilities Index-3 (HUI-3). Secondary outcomes were all-cause mortality, rehospitalizations, and hospital care costs. After adjustment by regression analysis, patients in the intervention group were less likely to present with decline in HRQoL after 3 months for the following dimensions: vision (odds ratio [OR] =0.33, 95% confidence interval [CI] =0.14-0.79), ambulation (OR =0.19, 95% CI =0.1-0.37), dexterity (OR =0.38, 95% CI =0.19-0.75), emotion (OR =0.43, 95% CI =0.22-0.84), cognition (OR = 0.076, 95% CI =0.033-0.18) and pain (OR =0.28, 95% CI =0.15-0.50). Treatment in a CGA unit was independently associated with lower 3-month mortality adjusted by Cox regression analysis (hazard ratio [HR] =0.55, 95% CI =0.32-0.96), and the two groups did not differ significantly in terms of hospital care costs ( P >0.05). Patients in an acute CGA unit were less likely to present with decline in HRQoL after 3 months, and the care in a CGA unit was also independently associated with lower mortality, at no higher cost.

  10. Global patterns of socioeconomic biomass flows in the year 2000. A comprehensive assessment of supply, consumption and constraints

    Human use of biomass has become a major component of the global biogeochemical cycles of carbon and nitrogen. The use of land for biomass production (e.g. cropland) is among the most important pressures on biodiversity. At the same time, biomass is indispensable for humans as food, animal feed, raw material and energy source. In order to support research into these complex issues, we here present a comprehensive assessment of global socioeconomic biomass harvest, use and trade for the year 2000. We developed country-level livestock balances and a consistent set of factors to estimate flows of used biomass not covered by international statistics (e.g. grazed biomass, crop residues) and indirect flows (i.e. biomass destroyed during harvest but not used). We found that current global terrestrial biomass appropriation amounted to 18.7 billion tonnes dry matter per year (Pg/yr) or 16% of global terrestrial NPP of which 6.6 Pg/yr were indirect flows. Only 12% of the economically used plant biomass (12.1 Pg/yr) directly served as human food, while 58% were used as feed for livestock, 20% as raw material and 10% as fuelwood. There are considerable regional variations in biomass supply and use. Distinguishing 11 world regions, we found that extraction of used biomass ranged from 0.3 to 2.8 t/ha/yr, per-capita values varied between 1.2 and 11.7 t/cap/yr (dry matter). Aggregate global biomass trade amounted to 7.5% of all extracted biomass. An analysis of these regional patterns revealed that the level of biomass use per capita is determined by historically evolved patterns of land use and population density rather than by affluence or economic development status. Regions with low population density have the highest level of per-capita biomass use, high-density regions the lowest. Livestock, consuming 30-75% of all harvested biomass, is another important factor explaining regional variations in biomass use. Global biomass demand is expected to grow during the next decades

    Sleep affects adolescents in various ways. However, the effects of multiple factors on sleep hygiene remain unclear. A comprehensive assessment of the effects of life habits on sleep in high-school students was conducted. A cross-sectional survey of 344 high school students (age range 15-17; 171 boys, 173 girls) in Tokyo, Japan was conducted in 2015. Complete responses were provided by 294 students. Demographic variables, Pittsburgh Sleep Quality Index (PSQI), diurnal type scale, Pediatric Daytime Sleepiness Scale (PDSS), and life habits such as dinnertime, viewing electronic displays, caffeine intake, sunlight in the morning, and the brightness of the room in the night were asked. The mean scores were PSQI: 5.9 (±2.3), PDSS: 19.0 (±5.8), and the diurnal type scale: 16.7 (±3.4). Using an electronic display in bed (OR = 3.01; (95%CI) 1.24-7.30), caffeine intake at night always (OR = 2.22; 1.01-4.90), and waking up before dawn (OR = 3.25; 1.34-7.88) were significantly associated with sleep disturbance. Irregular timing of the evening meal (OR = 2.06; 1.10-3.84) and display viewing within 2 h before bedtime (OR = 2.50; 1.01-6.18) or in bed (OR = 3.60; 1.41-9.21) were significantly associated with excessive daytime sleepiness. Using an electronic display within 2 h before bedtime (OR = 2.64; 1.10-6.38) or in bed (OR = 3.50; 1.40-8.76) and a living room which is bright at night (OR = 1.89; 1.06-3.36) were significantly associated with eveningness. Each type of sleep-related problem had its own associated life habit factors. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

    Energy-environmental planning must join normative, environmental and socio-economic features to obtain effective strategies aimed to a sustainable development. Therefore a comprehensive methodology for the analysis and the optimisation of the anthropogenic activities system configuration, can usefully support decision-makers in the definition of harmonised sector plans, joining waste management issues with resource use problems and exploiting energy and materials feedback among supply and demand sectors. In this paper we present an innovative application of the Advanced Local Energy Environmental Planning methodology (ALEP), aimed to the definition of optimal waste management strategies which comply with comprehensive as well as sectorial issues.

    Knowledge about predictors for reading comprehension in children with intellectual disabilities (ID) is still fragmented. This study compared reading comprehension, word decoding, listening comprehension, and reading related linguistic and cognitive precursor measures in children with mild ID and typically developing controls. Moreover, it was explored how the precursors related to reading achievement. Children with mild ID and typical controls were assessed on reading comprehension, decoding, language comprehension, and linguistic (early literacy skills, vocabulary, grammar) and cognitive (rapid naming, phonological short-term memory, working memory, temporal processing, nonverbal reasoning) precursor measures. It was tested to what extent variations in reading comprehension could be explained from word decoding, listening comprehension and precursor measures. The ID group scored significantly below typical controls on all measures. Word decoding was at or above first grade level in half the ID group. Reading comprehension in the ID group was related to word decoding, listening comprehension, early literacy skills, and temporal processing. The reading comprehension profile of children with mild ID strongly resembles typical early readers. The simple view of reading pertains to children with mild ID, with additional influence of early literacy skills and temporal processing. Copyright © 2016 Elsevier Ltd. All rights reserved.

  15. Returns to Scale and Damages to Scale with Strong Complementary Slackness Conditions in DEA Assessment: Japanese Corporate Effort on Environment Protection

    2012-01-01

    This study proposes a use of Data Envelopment Analysis (DEA) for environmental assessment. All organizations in private and public sectors produce not only desirable (good) but also undesirable (bad) outputs as a result of their economic activities. The proposed use of DEA determines the level of unified (operational and environmental) efficiency of all the organizations. A contribution of this study is that it explores how to measure not only RTS (Returns to Scale) on desirable outputs but also a new concept regarding “DTS: Damages to Scale” (corresponding to RTS for undesirable outputs). This study discusses how to measure RTS under natural disposability and DTS under managerial disposability by DEA. The measurement of RTS and DTS is formulated by incorporating “Strong Complementary Slackness Conditions (SCSCs)”. As a result, this study can handle an occurrence of multiple reference sets and multiple projections in the RTS/DTS measurement. The incorporation of SCSCs makes it possible both to restrict DEA multipliers in a specific range without any prior information and to identify all possible efficient organizations as a reference set. Using the unique capabilities of SCSCs, this study discusses the use of DEA environmental assessment by exploring how to classify the type of RTS/DTS with SCSCs. Such analytical capabilities are essential, but not previously explored in DEA environmental assessment for energy industries. As an illustrative example, this study applies the proposed approach for the performance evaluation of Japanese manufacturing industries. This study finds that these firms need to introduce technology innovation to reduce an amount of greenhouse gases and wastes. The empirical result confirms the importance of measuring RTS/DTS in DEA environmental assessment.

    The sword razor shell Ensis siliqua (Linnaeus, 1758) is a bivalve with a high commercial value being appreciated in fresh and processed markets. However, the genetic studies carried out in populations of E. siliqua are scarce. In this work, the genetic variability and differentiation of the sword razor shell was assessed using PCR-RFLPs of a fragment of the 16S rRNA mitochondrial gene and random amplified polymorphic loci (RAPD) in nine localities from Ireland, Spain, and Portugal. In the 314 individuals examined for the mitochondrial fragment, 12 composite haplotypes were observed; meanwhile, a unique phenotype was observed for each of the 242 individuals analyzed with 61 RAPD loci. Two of the mitochondrial composite haplotypes accounted for the majority of individuals (89.81%) and showed a remarkably disjoint distribution between Irish and Iberian samples, with the exception of Aveiro which exhibited as the most frequent haplotype the same found in Ireland. The level of variability observed for each sample was generally correlated with both types of markers and the results obtained suggest the existence of a strong population differentiation between Irish and Iberian localities, except for the Portuguese sample from Aveiro which is surprisingly closer to Irish individuals, although it is probably highly differentiated.

    Health literacy, or the ability to access, understand, appraise and apply health information, is central to individuals' health and well-being. A comprehensive, concept-based measure of most dimensions of health literacy has been developed for the general population in Europe, which enables comparisons within and between countries. This study seeks to validate this tool for use in Japan, and to use a Japanese translation to compare health literacy levels in Japan and Europe. A total of 1054 Japanese adults recruited through an Internet research service company, completed a Japanese-language version of the 47-item European Health Literacy Survey Questionnaire (HLS-EU-Q47). The survey was administered via an online questionnaire, and participant demographics were closely matched to those of the most recent Japanese national census. Survey results were compared with those previously reported in an eight-country European study of health literacy. Internal consistency for the translated questionnaire was valid across multiple metrics. Construct validity was checked using confirmatory factor analyses. The questionnaire correlated well with existing scales measuring health literacy and mental health status. In general, health literacy in the Japanese population was lower than in Europe, with Japanese respondents rating all test items as more difficult than European respondents. The largest difference (51.5 %) was in the number of respondents finding it difficult to know where to get professional help when they are ill. This study translated a comprehensive health literacy questionnaire into Japanese and confirmed its reliability and validity. Comparative results suggest that Japanese health literacy is lower than that of Europeans. This discrepancy may be partly caused by inefficiency in the Japanese primary health care system. It is also difficult to access reliable and understandable health information in Japan, as there is no comprehensive national online platform

    Cycle ergometer training (CET) has been shown to improve exercise performance of the quadriceps muscles in patients with COPD, and inspiratory muscle training (IMT) may improve the pressure-generating capacity of the inspiratory muscles. However, the effects of combined CET and IMT remain unclear and there is a lack of comprehensive assessment. Eighty-one patients with COPD were randomly allocated to three groups: 28 received 8 weeks of CET + IMT (combined training group), 27 received 8 weeks of CET alone (CET group), and 26 only received 8 weeks of free walking (control group). Comprehensive assessment including respiratory muscle strength, exercise capacity, pulmonary function, dyspnea, quality of life, emotional status, nutritional status, and body mass index, airflow obstruction, and exercise capacity index were measured before and after the pulmonary rehabilitation program. Respiratory muscle strength, exercise capacity, inspiratory capacity, dyspnea, quality of life, depression and anxiety, and nutritional status were all improved in the combined training and CET groups when compared with that in the control group ( P Inspiratory muscle strength increased significantly in the combined training group when compared with that in the CET group (ΔPI max [maximal inspiratory pressure] 5.20±0.89 cmH 2 O vs 1.32±0.91 cmH 2 O; P 0.05). Patients with weakened respiratory muscles in the combined training group derived no greater benefit than those without respiratory muscle weakness ( P >0.05). There were no significant differences in these indices between the patients with malnutrition and normal nutrition after pulmonary rehabilitation program ( P >0.05). Combined training is more effective than CET alone for increasing inspiratory muscle strength. IMT may not be useful when combined with CET in patients with weakened inspiratory muscles. Nutritional status had slight impact on the effects of pulmonary rehabilitation. A comprehensive assessment approach can be more

    Functional decline in community-dwelling older persons is associated with the loss of independence, the need for hospital and nursing-home care and premature death. The effectiveness of multifactorial interventions in preventing functional decline remains controversial. The aim of this study is to investigate whether functional decline in community-dwelling older persons can be delayed or prevented by a comprehensive geriatric assessment, multifactorial interventions and nurse-led care coordination. In a cluster randomized controlled trial, with the general practice as the unit of randomization, 1281 participants from 25 general practices will be enrolled in each condition to compare the intervention with usual care. The intervention will focus on older persons who are at increased risk for functional decline, identified by an Identification of Seniors at Risk Primary Care (ISAR-PC) score (≥ 2).

    Full Text Available The academic debate nowadays is focused on producing an applied science of learning, aiming to teach students how to learn and be strategic in their acquisition. The aim of the study is to identify and discuss the reading comprehension instruction approach applied in the Albanian system of education. Findings from 10 classes of Albanian language and literature with students of third grade were directly observed and analyzed, in order to gather evidence based on indicators and instruments that assess the way of reading comprehension. Findings were categorized according to strategy use; the frequency of their application in different classes was counted and represented in percentages. In this paper we will try to respond to questions like: What are students' main barriers of comprehending? Does the instructional approach respond to students’ needs and level of comprehension? Are teachers prepared to teach comprehension strategies? Furthermore, examples of procedures on how to deliver instruction of comprehension strategies in natural contexts will be represented. Results from teacher practices during lessons of reading comprehension confirmed that teachers use limited teaching strategies to deliver lessons. They mainly use strategies to test comprehension; while the approach of teaching students to read independently and strategically is an unknown practice.

    Systematic analysis of STD programme data contributes to a national portrait of sexually transmitted disease (STD) prevention activities, including research and evaluation specifically designed to optimise programme efficiency and impact. We analysed the narrative of the 2009 annual progress reports of the US Comprehensive STD Prevention Systems cooperative agreement for 58 STD programmes, concentrating on programme characteristics and partnerships. Programmes described 516 unique partnerships with a median of seven organisations cited per STD programme. Non-profit organisations (including service providers) were most frequently cited. Higher gonorrhoea morbidity was associated with reporting more partnerships; budget problems were associated with reporting fewer. Challenges to engaging in partnerships included budget constraints, staff turnover and low interest. Data provide a source of information for judging progress in programme collaboration and for informing a sustained programme-focused research and evaluation agenda.

    The purposes of this study were (a) to describe the adaptation and psychometric properties of the Skills for Cognitive Therapy (SoCT) measure for use by an independent observer (SoCT-IO) who rates the cognitive therapy (CT) skill acquisition, comprehension, and use by depressed adults and (b) to compare ratings of CT skill comprehension, acquisition, and use by independent observers to those by patients and therapists. Like the other SoCT versions, the SoCT-IO consists of 8 items that assess patients' comprehension, acquisition, and use of cognitive and behavioral skills for managing depressive symptoms, using a 5-point Likert-type scale. Four experienced raters (2 doctoral-level CT therapists and 2 bachelor-level nontherapists) used the SoCT-IO to rate 80 CT videotapes from both mid and later sessions in acute-phase CT from a randomized controlled trial for outpatients with recurrent major depression. The SoCT-IO ratings showed excellent internal consistency reliability and moderately high interrater reliability. Concurrent validity was demonstrated by convergence of the SoCT-IO with 2 other versions of the SoCT, 1 completed by therapists (SoCT-O) and the other by patients (SoCT-P). SoCT-IO ratings evidenced good predictive validity: Independent observers' ratings of patient CT skills midphase in therapy predicted treatment response even when the predictive effects of SoCT ratings by therapists and patients were controlled. The SoCT-IO is a psychometrically sound measure of CT skill comprehension, acquisition and use for rating outpatients with recurrent depression. The clinical utility and implications for using the SoCT-IO as a measure of CT skills acquisition are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Previous research suggests that being interrupted while reading a text does not disrupt the later recognition or recall of information from that text. This research is used as support for Ericsson and Kintsch's (1995) long-term working memory (LT-WM) theory, which posits that disruptions while reading (e.g., interruptions) do not impair subsequent text comprehension. However, to fully comprehend a text, individuals may need to do more than recognize or recall information that has been presented in the text at a later time. Reading comprehension often requires individuals to connect and synthesize information across a text (e.g., successfully identifying complex topics such as themes and tones) and not just make a familiarity-based decision (i.e., recognition). The goal for this study was to determine whether interruptions while reading disrupt reading comprehension when the questions assessing comprehension require participants to connect and synthesize information across the passage. In Experiment 1, interruptions disrupted reading comprehension. In Experiment 2, interruptions disrupted reading comprehension but not recognition of information from the text. In Experiment 3, the addition of a 15-s time-out prior to the interruption successfully removed these negative effects. These data suggest that the time it takes to process the information needed to successfully comprehend text when reading is greater than that required for recognition. Any interference (e.g., an interruption) that occurs during the comprehension process may disrupt reading comprehension. This evidence supports the need for transient activation of information in working memory for successful text comprehension and does not support LT-WM theory. (c) 2015 APA, all rights reserved).

    A variety of cardiac magnetic resonance indexes predict mid-term prognosis in ST-segment elevation myocardial infarction patients. The extent of transmural necrosis permits simple and accurate prediction of systolic recovery. However, its long-term prognostic value beyond a comprehensive clinical and cardiac magnetic resonance evaluation is unknown. We hypothesized that a simple semiquantitative assessment of the extent of transmural necrosis is the best resonance index to predict long-term outcome soon after a first ST-segment elevation myocardial infarction. One week after a first ST-segment elevation myocardial infarction we carried out a comprehensive quantification of several resonance parameters in 206 consecutive patients. A semiquantitative assessment (altered number of segments in the 17-segment model) of edema, baseline and post-dobutamine wall motion abnormalities, first pass perfusion, microvascular obstruction, and the extent of transmural necrosis was also performed. During follow-up (median 51 months), 29 patients suffered a major adverse cardiac event (8 cardiac deaths, 11 nonfatal myocardial infarctions, and 10 readmissions for heart failure). Major cardiac events were associated with more severely altered quantitative and semiquantitative resonance indexes. After a comprehensive multivariate adjustment, the extent of transmural necrosis was the only resonance index independently related to the major cardiac event rate (hazard ratio=1.34 [1.19-1.51] per each additional segment displaying>50% transmural necrosis, P<.001). A simple and non-time consuming semiquantitative analysis of the extent of transmural necrosis is the most powerful cardiac magnetic resonance index to predict long-term outcome soon after a first ST-segment elevation myocardial infarction.

    This report discusses the scope of risk assessment strategies in the management of the transport of high-level radioactive wastes. In spite of the shortcomings of probabilistic risk assessment(PRA), the Transportation Needs Assessment recommended this as the preferred methodology to assess the risks of high level nuclear waste (HLNW) transportation. A PRA also will need to heed the lessons learned from the development and application of PRA elsewhere, such as in the nuclear power industry. A set of guidelines will aid this endeavor by outlining the appropriate scope, content, and use of a risk assessment which is more responsive to the uncertainties, human-technical interactions, social forces, and iterative relationship with risk management strategies, than traditional PRAS. This more expansive definition, which encompasses but is not totally reliant on rigorous data requirements and quantitative probability estimates, we term Comprehensive Risk Assessment (CRA) Guidelines will be developed in three areas: the limitations of existing methodologies and suggested modifications; CRA as part of a flexible, effective, adaptive risk management system for HLNW transportation; and, the use of CRA in risk communication

    Long-term-care comprehensive geriatric assessments, such as the Minimum Data Set 3.0, are used to evaluate the clinical, psychological, and personal status of residents in long-term-care nursing facilities. Nursing staff conducts assessment interviews, thereby increasing the workload of nurses and the cost of patient care. This study explored the ability of nursing home residents to use two different mobile devices for a geriatric self-assessment. Study participants were residents of long-term-care nursing homes. A modified Minimum Data Set 3.0 was converted to a format for use with a 6-inch mobile pad and a 3.7-inch mobile smartphone. The survey completion rate and the response time were measured. A Technology Assessment Model questionnaire analyzed the participants' experience. All participants were able to use a 6-inch pad, with an average completion rate of 92.9% and an average time for completion of 21 minutes. Only 20% of the participants could complete the assessment with the 3.7-inch smartphone. The participants found the 6-inch pad easier to use than the 3.7-inch smartphone. This exploratory study suggests that nursing home residents are able to use a mobile device to perform a geriatric self-assessment and delineates the importance of the ergonomics of the device.

The core of the “One Belt, One Road” strategy initiative is to promote infrastructure construction and interconnection, dock national policies and development strategies, deepen pragmatic cooperation, promote coordinated and coordinated development and achieve common prosperity. With the “The Belt and Road” strategy in-depth, Chinese enterprises will go abroad, in the countries along the country to invest in more and more examples, accompanied by the increasing risk. Analysis of the failure of investment cases, we can easily find that this is the majority of enterprises overseas investment in the lack of careful assessment of risk and risk of foreign investment risk management has a great relationship. In this paper, the risk factors are used to identify the risk factors table, and the fuzzy comprehensive evaluation method is used to estimate the comprehensive risk value of many uncertain factors that cannot be determined by the overseas investment. The risk assessment system is constructed to help Chinese enterprises to follow the " Investment to avoid risks, improve the success rate.

    To determine how best to measure the provision of comprehensive preventive care assessment of adults with intellectual and developmental disabilities (IDD). Cross-sectional study. Ontario. Adults with IDD between 40 and 64 years of age in 2013 and 2014. Health examination was defined using the Ontario Health Insurance Plan billing data fee code A003 (with diagnostic code 917 or 319) or fee code K131, and the Primary Care Quality Composite Score (PCQS), a measure combining 7 different screening maneuvers (lipid, glucose, breast cancer, cervical cancer, colorectal cancer, eye, and hemoglobin A 1c screening), was identified using administrative health data. A total of 28 825 adults with IDD were identified in 2013 and 2014. Overall, 12.1% of adults with IDD received a health examination; 51.2% received a high (≥ 0.6) PCQS. Male patients were more likely to have received all of their eligible screening maneuvers if they had had a health examination compared with female patients (odds ratio of 5.73 vs 3.99, respectively). Less than 60% of adults with IDD appear to be receiving comprehensive preventive care. Future studies assessing the quality of preventive care received by adults with IDD should combine health examination billing codes and the PCQS.

    Full Text Available Abstract Background In highly copy number variable (CNV regions such as the human defensin gene locus, comprehensive assessment of sequence variations is challenging. PCR approaches are practically restricted to tiny fractions, and next-generation sequencing (NGS approaches of whole individual genomes e.g. by the 1000 Genomes Project is confined by an affordable sequence depth. Combining target enrichment with NGS may represent a feasible approach. Results As a proof of principle, we enriched a ~850 kb section comprising the CNV defensin gene cluster DEFB, the invariable DEFA part and 11 control regions from two genomes by sequence capture and sequenced it by 454 technology. 6,651 differences to the human reference genome were found. Comparison to HapMap genotypes revealed sensitivities and specificities in the range of 94% to 99% for the identification of variations. Using error probabilities for rigorous filtering revealed 2,886 unique single nucleotide variations (SNVs including 358 putative novel ones. DEFB CN determinations by haplotype ratios were in agreement with alternative methods. Conclusion Although currently labor extensive and having high costs, target enriched NGS provides a powerful tool for the comprehensive assessment of SNVs in highly polymorphic CNV regions of individual genomes. Furthermore, it reveals considerable amounts of putative novel variations and simultaneously allows CN estimation.

    To assess the availability and coverage of publicly available road safety data at the national and state levels in India. We reviewed the 2 publicly accessible data sources in India for the availability of data related to traffic injuries and deaths: (1) the National Crime Records Bureau (NCRB) and (2) the Ministry of Road Transport and Highways (MORTH). Using the World Health Organization (WHO) manual for the comprehensive assessment of road safety data, we developed a checklist of indicators required for comprehensive road safety assessment. These indicators were then used to assess the availability of road safety data in India using the NCRB and MORTH data. We assessed the availability of data on outcomes and exposures indicators (i.e., number of crashes, injuries, deaths, timing of deaths, gender and age distribution of injuries and deaths), safety performance indicators (i.e., with reference to select risk factors of speeding, alcohol, and helmet use), and cost indicators (i.e., medical costs, material costs, intervention costs, productivity costs, time costs, and losses to quality of life). Information on outcome indicators was the most comprehensive in terms of availability. Both NCRB and MORTH databases had data for most of the need areas specified by the WHO under outcomes and exposure indicators. Regarding outcome and exposure indicators, data were available for 81 and 91 percent of specified need areas at the national level from NCRB and MORTH databases, respectively. At the state level, data on outcome and exposure indicators were available for only 54 percent of need areas from either of the 2 sources. There were no data on safety performance indicators in the NCRB database. From the MORTH database, data availability on safety performance indicators was 60 percent at both national and state levels. Data availability on costs and process indicators was found to be below 20 percent at the national and state levels. Overall, there is an urgent need to

    Around 2000, China began to address the comprehensive restoration of its urban rivers and attempt to restore river ecosystem services. This paper reports an integrated contingent valuation of the ecosystem services of Zhangjiabang Creek in Shanghai, which is in the most developed region of China. A total of 1440 questionnaires were delivered, and 1153 were returned as usable in August 2008. The willingness to pay for the restoration of the urban river is 20.22 RMB (2.91 USD) per month per household under the payment card and 110.64 RMB (15.92 USD) under the dichotomous format. Several important methodological issues of the contingent valuation method (CVM) are observed, including the disparity between willingness to pay and willingness to accept, the difference between payment card and dichotomous choice question formats, and the comparison of different models in welfare estimation using dichotomous choice data. Several new findings are disclosed for these three issues of CVM. Copyright © 2013 Elsevier B.V. All rights reserved.

    Elderly in Egypt is approximately 7.2% of the population. The main physical health problems affecting old age is Non-communicable diseases (NCDs). Depression is the commonest geriatric psychiatric disorder related to various life events. Malnutrition is associated with poor health, and cognitive impairment. To determine the prevalence of chronic non-communicable diseases; malnutrition and depression with identification of related risk factors among Fayoum elderly population. A cross-sectional descriptive community based survey was conducted among elderly population 2219 in Fayoum governorate. The sample was multistage stratified cluster random. An interview structured questionnaire including socio-demographic characteristics, history of chronic NCDs, evaluation of nutritional and psychological status by MNASF and GDSLF tools respectively. More than ninety percent of the studied population was suffering from more than one disease either physiological or pathological. The prevalence of malnutrition and depression was 10.9% and 74.5% respectively. Logistic regression analysis revealed that female gender, with increased age, and disease burden were common risk factor for both malnutrition and depression. Non-communicable disease, malnutrition and depression were prevalent in our older population. These findings indicated the need for comprehensive integrated medical, psychological and nutritional health care at the level of the primary health care units. Copyright © 2016 Elsevier Ireland Ltd.

    OBJECTIVES: The costs of comprehensive cardiac rehabilitation are established and compared to the corresponding costs of usual care. The effect on health-related quality of life is analyzed. METHODS: An unprecedented and very detailed cost assessment was carried out, as no guidelines existed...... for the situation at hand. Due to challenging circumstances, the cost assessment turned out to be ex-post and top-down. RESULTS: Cost per treatment sequence is estimated to be approximately euro 976, whereas the incremental cost (compared with usual care) is approximately euro 682. The cost estimate is uncertain...... and may be as high as euro 1.877. CONCLUSIONS: Comprehensive cardiac rehabilitation is more costly than usual care, and the higher costs are not outweighed by a quality of life gain. Comprehensive cardiac rehabilitation is, therefore, not cost-effective....

    We describe a 68-year-old man with acute stroke in whom the newly developed single sweep method for three-dimensional (3D) carotid ultrasound provided a rapid and comprehensive assessment of atherosclerotic plaque burden in the internal carotid artery. The two-dimensional duplex carotid scan diagnosed 50-69% stenosis, and with the three-dimensional method, the markedly hypoechogenic plaque (total volume 1.42 mL) was shown to occupy 77% of the total arterial volume (1.84 mL), consistent with severe lesion. The ultrasound findings were confirmed by computed tomographic angiography and subsequent carotid endarterectomy. The new single sweep 3D carotid ultrasound has the potential to become a valuable clinical tool in the assessment of stroke patients. © 2013, Wiley Periodicals, Inc.

    Our aim was to assess the impact of increase in homeostasis model assessment of insulin resistance (HOMA-IR) on the development of type 2 diabetes in Japanese individuals with impaired insulin secretion (IIS). This study included 2,209 participants aged 30-69 without diabetes at baseline who underwent comprehensive medical check-ups between April 2006 and March 2007 at Saku Central Hospital. Participants were classified into eight groups according to the combination of baseline IIS status (non-IIS and IIS) and category of HOMA-IR change between the baseline and follow-up examinations (decrease, no change/small increase, moderate increase, and large increase). Type 2 diabetes was determined from fasting and 2 h post-load plasma glucose concentrations at the follow-up examination between April 2009 and March 2011. At baseline, 669 individuals (30.3%) were classified as having IIS. At follow-up, 74 individuals developed type 2 diabetes. After adjusting for confounding factors including baseline HOMA-IR values, the multivariable-adjusted odds ratios (95% confidence intervals) for type 2 diabetes in the non-IIS with a decrease (mean change in HOMA-IR: -0.47), non-IIS with a moderate increase (mean change in HOMA-IR: 0.28), non-IIS with a large increase (mean change in HOMA-IR: 0.83), IIS with a decrease (mean change in HOMA-IR: -0.36), IIS with no change/small increase (mean change in HOMA-IR: 0.08), IIS with a moderate increase (mean change in HOMA-IR: 0.27), and IIS with a large increase (mean change in HOMA-IR: 0.73) groups, relative to the non-IIS with no change/small increase (mean change in HOMA-IR: 0.08) group were 0.23 (0.04, 1.11), 1.22 (0.26, 5.72), 2.01 (0.70, 6.46), 1.37 (0.32, 4.28), 3.60 (0.83, 15.57), 5.24 (1.34, 20.52), and 7.01 (1.75, 24.18), respectively. Moderate and large increases in HOMA-IR had a strong impact on the development of type 2 diabetes among individuals with IIS in this Japanese population.

    Chromium (Cr) pollution caused by wastewater from tanneries is a worldwide environmental problem. To develop a countermeasure, we performed a comprehensive study using Hazaribagh, the tannery area in Dhaka City, Bangladesh, as a model. Our environmental monitoring indicated that the soluble form of Cr, but not barium or arsenic, in Buriganga River is derived from Hazaribagh. Our chemical analysis next showed that Cr, the primary pollutant in canal water at Hazaribagh, consisted of ≤0.7 μM hexavalent Cr [Cr(VI)] and ≤1705 μM trivalent Cr [Cr(III)]. Our biological study then showed that coexposure to Cr(VI) and Cr(III) at possible ratios in canal water at Hazaribagh synergistically promotes transforming activity of human non-tumorigenic HaCaT keratinocytes with activated MEK/ERK and AKT. Our environmental engineering study finally indicated that a magnesium and iron-based hydrotalcite-like compound (MF-HT), our original depurative, can maximally adsorb 9.0 mg/g Cr(VI) and 1041 mg/g Cr(III). Our results suggested the importance of removal of Cr(III) as well as Cr(VI) by showing that Cr(III), which is generally recognized as a chemical with low toxicity, synergistically promoted carcinogenicity of a low level of Cr(VI). Therefore, we propose the use of our original high-efficient and low-cost depurative as a countermeasure to address the worldwide problem of environmental Cr pollution. Copyright © 2018 Elsevier Ltd.

    Withania somnifera (L.) Dunal (Family, Solanaceae), is among the most valuable medicinal plants used in Ayurveda owing to its rich reservoir of pharmaceutically active secondary metabolites known as withanolides. Withanolides are C 28 -steroidal lactones having a triterpenoidal metabolic origin synthesised via mevalonate (MVA) pathway and methyl-D-erythritol-4-phosphate (MEP) pathway involving metabolic intermediacy of 24-methylene (C 30 -terpenoid) cholesterol. Phytochemical studies suggest differences in the content and/or nature of withanolides in different tissues of different chemotypes. Though development of genomic resources has provided information about putative genes encoding enzymes for biosynthesis of intermediate steps of terpenoid backbone, not much is known about their regulation and response to elicitation. In this study, we generated detailed molecular information about genes catalysing key regulatory steps of withanolide biosynthetic pathway. The full-length sequences of genes encoding enzymes for intermediate steps of terpenoid backbone biosynthesis and their paralogs have been characterized for their functional and structural properties as well as phylogeny using bioinformatics approach. The expression analysis suggests that these genes are differentially expressed in different tissues (with maximal expression in young leaf), chemotypes and in response to salicylic acid (SA) and methyl jasmonate (MJ) treatments. Sub-cellular localization studies suggest that both paralogs of sterol ∆-7 reductase (WsDWF5-1 and WsDWF5-2) are localized in the endoplasmic reticulum (ER) thus supporting their indispensible role in withanolide biosynthesis. Comprehensive information developed, in this study, will lead to elucidation of chemotype- as well as tissue-specific withanolide biosynthesis and development of new tools for functional genomics in this important medicinal plant.

    The objectives of this study were to investigated changes in OHRQoL among patients with different classifications of malocclusion during comprehensive orthodontic treatment. Clinical data were collected from 81 patients (aged 15 to 24) who had undergone comprehensive orthodontic treatment. Participants were classified 3 groups: Class I (n = 35), II (n = 32) and III (n = 14) by Angle classification. OHRQoL was assessed using the Oral Health Impact Profile (OHIP-14). All subjects were examined and interviewed at baseline (T0), after alignment and leveling (T1), after correction of molar relationship and space closure (T2), after finishing (T3). Friedman 2-way analysis of variance (ANOVA) and Wilcoxon signed rank tests were used to compare the relative changes of OHRQoL among the different time points. A Bonferroni correction with P  0.005) in class I and class II, Handicap in class II and class III (P > 0.005). Class I patients showed significant changes for psychological disability and psychological discomfort domain at T1, functional limitation, physical pain at T2. Class III patients showed a significant benefit in all domains except physical pain and functional limitation. Class II patients showed significant changes in the physical pain, functional disability, and physical disability domains at T1. The impact of comprehensive orthodontic treatment on patients' OHRQoL do not follow the same pattern among patients with different malocclusion. Class II patients benefits the most from the stage of space closure, while class I patients benefits the first stage (alignment and leveling) of treatment in psychological disability and psychological discomfort domains.

    The objective of this study was to conduct a comprehensive formative assessment of chronic pain management in a large, multisite community health centre and use the results to design a quality improvement initiative based on an evidence-based practice model developed by the Veterans Health Administration. Improving quality and safety by incorporating evidence-based practices (EBP) is challenging, particularly in busy clinical practices such as Federally Qualified Health Centers (FQHCs). FQHCs grapple with financial constraints, lack of resources and complex patient populations. The Promoting Action on Research Implementation in Health Services (PARIHS) Framework served as a basis for the comprehensive assessment. We used a range of measures and tools to examine pain care from a variety of perspectives. Patients with chronic pain were identified using self-reported pain scores and opioid prescription records. We employed multiple data collection strategies, including querying our electronic health records system, manual chart reviews and staff surveys. We found that patients with chronic pain had extremely high primary care utilisation rates while referral rates to pain-related specialties were low for these patients. Large gaps existed in primary care provider adherence to standards for pain care documentation and practice. There was wide provider variability in the prescription of opioids to treat pain. Staff surveys found substantial variation in both pain care knowledge and readiness to change, as well as low confidence in providers' ability to manage pain, and dissatisfaction with the resources available to support chronic pain care. Improving chronic pain management at this Community Health Center requires a multifaceted intervention aimed at addressing many of the problems identified during the assessment phase. During the intervention we will put a greater emphasis on increasing options for behavioural health and complementary medicine support, increasing

    Cancer patients suffer from a variety of physical and mental complaints. Since physician assessment of symptoms seems insufficient to reveal the complete range of patients' ailments, patient-reported outcomes (PRO) have become of key importance in modern cancer treatment. The implementation and first results of a systematic electronic real-time assessment of PRO in routine care is described. Consecutive patients presenting for the first time to a German comprehensive cancer center were asked to fill in an adaptive self-administered electronic questionnaire consisting of standardized PRO measures. After completion, patient-reported data was linked to the patients' medical files for discussion in the first consultation with the treating physician. Interviews with staff were conducted to identify barriers in implementation. Out of 160 cancer patients, 126 (79 %; mean age 63 years, 67 % males) agreed to participate. The number of recruited patients increased over time. Of participating patients, 67 % provided complete information on all PRO-related scales. On average, 31 min (range 3-140) were required to fill in the questionnaire. Of participating patients, 53.0 % comprised need for psychooncological support and 62 % revealed moderate to severe psychosocial distress. The mean score for global quality of life according to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) was 55.2 (SD ±25.6). Comprehensive oncological treatment needs to consider disease symptoms, quality of life, preferences, and comorbidities of individual patients in a structured, standardized, and transparent way. Our findings indicate that an adaptive, self-administered electronic assessment tool for cancer patients to report a broad set of PRO can be feasibly implemented and is well accepted by patients in a realistic setting.

    Highlights: • A methodological approach by NMR was developed to assess the safety of food contact materials. • Additives from PLA were rapidly identified by an automatic NMR methodology coupled with dedicated database. • Quantitative NMR (qNMR) allowed to quantify 12 additives in three types of polylactide. • qNMR is as sensitive as chromatographic methods to quantify additives in PLA. - Abstract: A nuclear magnetic resonance (NMR) methodology was assessed regarding the identification and quantification of additives in three types of polylactide (PLA) intended as food contact materials. Additives were identified using the LNE/NMR database which clusters NMR datasets on more than 130 substances authorized by European Regulation No. 10/2011. Of the 12 additives spiked in the three types of PLA pellets, 10 were rapidly identified by the database and correlated with spectral comparison. The levels of the 12 additives were estimated using quantitative NMR combined with graphical computation. A comparison with chromatographic methods tended to prove the sensitivity of NMR by demonstrating an analytical difference of less than 15%. Our results therefore demonstrated the efficiency of the proposed NMR methodology for rapid assessment of the composition of PLA

    The SECURE Water Act § 9503(b)(2) authorizes the U.S. Department of Interior's Bureau of Reclamation to assess climate change risks for water and environmental resources in eight "major Reclamation river basins" in the Western United States (i.e. Colorado, Columbia, Klamath, Missouri, Rio Grande, Sacramento, San Joaquin, and Truckee basins). The legislation calls for Reclamation to provide periodic reports on implications for water supplies, water deliveries, hydropower generation, fish and wildlife, water quality, flood control, ecological resiliency, and recreation. Reclamation's is developing a framework for consistently characterizing risks in Western U.S. river basins through the West-Wide Climate Risk Assessments, part of the Basin Study Program. One initial activity within this framework is focused on characterizing hydrologic and water supply implications of climate change. The centerpiece of this activity is the development of a west-wide ensemble of hydrologic projections, tiering from information in the online archive "Bias Corrected and Downscaled WCRP CMIP3 Climate Projections" (http://gdo-dcp.ucllnl.org/downscaled_cmip3_projections/dcpInterface.html) and utilizing a network of hydrologic model applications featured in the University of Washington and Princeton University's "Experimental National Hydrologic Prediction System" (http://www.hydro.washington.edu/forecast/westwide/index.shtml). The resulting hydrologic information has the same space and time attributes as the underlying downscaled climate information: 112 projections of monthly downscaled CMIP3 conditions from 1950-2099 at 1/8° resolution over the Western U.S. (nested within the underlying archive’s contiguous U.S. domain). Such attributes permit a time evolving risk-based portrayal of hydrologic conditions, which is useful for climate change adaptation discussions where the timing of impacts matters in relation the initiation and investment of adaptation or mitigation measures

    Mineralogical analyses of clinical samples have been proved useful to identify causal relationship between exposure to airborne particles and pulmonary diseases. The most striking example is asbestosis where the assessment of asbestos bodies in patient lung samples has allowed defining values specific of pathologies. However, this type of analyses only considers the micro-sized fraction of the particles, neglecting the specific impact of nano-sized particles which have been otherwise shown to be reactive and able to induce biological effects. Similarly, in nanotoxicology, the mineralogical analysis of pulmonary fluids could be used as an indicator of exposure to inhaled nanoparticles and could help investigations on the relationship between exposure to these nanoparticles and lung diseases. We designed this study first to demonstrate the technical feasibility of this approach, then to get a clear picture of the metals present, and in what form, in patient lungs and finally to determine if indeed it is worth investigating separately the micro, sub-micro and nano fractions. Broncho-alveolar lavages were recovered from 100 patients suffering from interstitial lung diseases. A protocol was specifically developed to isolate three fractions containing respectively microparticles, sub-microparticles and nanoparticles with ions. The metal content in each fraction was qualitatively and quantitatively characterized. Results showed significant differences between the three fractions in terms of metal load confirming that the separate analysis of the fractions is relevant. It also means that the assessment of the micro-sized fraction alone, as commonly done in clinical practice, only gives a partial view of the mineralogical analysis.

    It has been proposed that the offspring of parents with bipolar disorder (OBD), through genetic mechanisms and early family interactions, develop a heightened sensitivity to stress, maladaptive coping, and dysregulated behavior, which ultimately increases the risk for affective disorders. The current study tested certain predictions of this model by assessing different psychosocial and health-related outcomes in the OBD, including personality, coping style, smoking, suicidality, high-risk sexual behaviors, criminality, and mental health. The sample was composed of 74 OBD and 75 control offspring, who were between 14 and 27 years of age (mean: 19.38±3.56). Participants underwent a diagnostic interview and a structured interview to assess high-risk behavior and other maladaptive outcomes, and they completed the Revised NEO Personality Inventory and Coping in Stressful Situations questionnaire. The rates of affective (31.1%) and non-affective (56.8%) disorders were elevated in the OBD compared to controls (9.5% and 32.4%). Relative to controls, OBD endorsed fewer task-oriented and more distraction coping strategies [Wilk׳s λ=.83, F(1, 136) =6.92, p<.01], and were more likely to report engaging in high-risk sexual behavior (OR=2.37; Wald=4.13, 1 df, p<05). Importantly, OBD reported elevated high-risk sexual behavior relative to controls, irrespective of affective disorder diagnosis. The results highlight a potential risk profile for the OBD, consisting of ineffective coping strategies and risky sexual behavior and are discussed in the context of current knowledge of stress and coping in this population. The present findings were based on cross-sectional data and relied on offspring self-report. It would be useful to corroborate these findings with biobehavioural and longitudinal measures.

    The Comprehensive Assessment of Psychopathic Personality (CAPP) is a concept map of psychopathic personality disorder (PPD). The CAPP- Institutional Rating Scale (IRS) is a tool designed to assess CAPP symptoms in institutional settings. The CAPP contains 33 personality traits organized in six domains: attachment, behavioural, cognitive, dominance, emotional and self. Until now, much of the CAPP research has been conducted out of clinical, forensic and correctional settings using self-ratings. In the current study, the psychometric properties and construct validity of the CAPP-IRS were evaluated in a non-convenience sample of 204 Spanish convicts. Clinician ratings were employed. Participants had been imprisoned for at least 6 months at Pereiro de Aguiar Penitentiary. This group of inmates was heterogeneous with respect to type of official charges, and representative as all convicts interned for at least 6 months in this prison were screened for participation. Classical test theory indexes of reliability, correlations between CAPP items and domains and external correlations and structural analyses demonstrated that CAPP assessment is a solid and robust way of evaluating psychopathy in a correctional setting. Best fit was found for a three-factor model: attachment and emotional items associated with a callous and unemotional trait, dominance and self items associated with a pathological interpersonal style, and behavioural and residual items from other domains associated with impulsivity.

    This paper describes the assessment method of measures mitigating heat island phenomena in urban areas. The heat island phenomena were classified into meso-scale with 100 km-scale, block-scale with several km-scale, and building-scale with 100 m-scale. Urban thermal environment simulation model was developed in response to each scale. For the development, regional data using aircraft and artificial satellite observations, surface observation and thermal environment observation at Shinjuku new central city of Tokyo, and artificial waste heat actual survey data in the southern Kanto district were utilized. Results of the urban thermal environment simulation were introduced as an application of this model. Temperature distributions of the heat island in the Kanto district were simulated with considering urban conditions near Tokyo and without considering it.

    Purpose To retrospectively validate a first-pass analysis (FPA) technique that combines computed tomographic (CT) angiography and dynamic CT perfusion measurement into one low-dose examination. Materials and Methods The study was approved by the animal care committee. The FPA technique was retrospectively validated in six swine (mean weight, 37.3 kg ± 7.5 [standard deviation]) between April 2015 and October 2016. Four to five intermediate-severity stenoses were generated in the left anterior descending artery (LAD), and 20 contrast material-enhanced volume scans were acquired per stenosis. All volume scans were used for maximum slope model (MSM) perfusion measurement, but only two volume scans were used for FPA perfusion measurement. Perfusion measurements in the LAD, left circumflex artery (LCx), right coronary artery, and all three coronary arteries combined were compared with microsphere perfusion measurements by using regression, root-mean-square error, root-mean-square deviation, Lin concordance correlation, and diagnostic outcomes analysis. The CT dose index and size-specific dose estimate per two-volume FPA perfusion measurement were also determined. Results FPA and MSM perfusion measurements (P FPA and P MSM ) in all three coronary arteries combined were related to reference standard microsphere perfusion measurements (P MICRO ), as follows: P FPA_COMBINED = 1.02 P MICRO_COMBINED + 0.11 (r = 0.96) and P MSM_COMBINED = 0.28 P MICRO_COMBINED + 0.23 (r = 0.89). The CT dose index and size-specific dose estimate per two-volume FPA perfusion measurement were 10.8 and 17.8 mGy, respectively. Conclusion The FPA technique was retrospectively validated in a swine model and has the potential to be used for accurate, low-dose vessel-specific morphologic and physiologic assessment of coronary artery disease. © RSNA, 2017.

    Human enterovirus 71 (EV71) is a causative agent of hand, foot, and mouth disease (HFMD). In a previous phase III trial in children, a human diploid cell-based inactivated EV71 vaccine elicited EV71 specific immune responses and protection against EV71 associated HFMD. This study aimed to assess the factors influencing the severity of adverse events observed in this previous trial. This was a randomized, double-blinded, placebo-controlled, phase III clinical trial of a human diploid vaccine carried out in 12,000 children in Guangxi Zhuang Autonomous Region, China (ClinicalTrials.gov: NCT01569581). Solicited events were recorded for 7 days and unsolicited events were reported for 28 days after each injection. Age trend analysis of adverse reaction was conducted in each treatment group. Multiple logistic regression models were built to identify factors influencing the severity of adverse reactions. Fewer solicited adverse reactions were observed in older participants within the first 7 days after vaccination (P < 0.0001), except local pain and pruritus. More severe adverse reactions were observed after the initial injection than after the booster injection. Serious cold or respiratory tract infections (RTI) were observed more often in children aged 6-36 months than in older children. Only the severity of local swelling was associated with body mass index. Children with throat discomfort before injection had a higher risk of serious cold or RTI. These results indicated that the human diploid cell-based vaccine achieved a satisfactory safety profile.

    This study examined working memory contributions to reading comprehension subskills in Greek children (mean age 9 years, 1 month). The phonological loop of the Baddeley and Hitch working memory model was assessed with 3 recall tasks (words, nonwords, and digits) and a word list matching task. The central executive (CE) was assessed with 3 tasks (listening, counting, and backward digit recall). Participants were also given a receptive vocabulary task, a reading fluency task, and written stories accompanied by comprehension questions. Canonical correlation analyses showed that the comprehension variables were related to the CE rather than the phonological loop measures. CE functions were more strongly associated with elaborative inference generation (involving significant offline processing) and comprehension control (involving metacognitive monitoring). Smaller yet significant associations were observed between the CE and the necessary inference and literal comprehension measures, whereas a moderate relationship was found in the case of the simile comprehension variable. Among the CE variables, listening recall demonstrated the highest loading on the canonical function, followed by moderate yet significant counting and backward digit recall loadings. Vocabulary was found to fully mediate several associations between working memory and comprehension measures; however, the relationship between listening recall and elaborative inferences was partly mediated. Reading fluency and, on several occasions, Greek vocabulary knowledge did not mediate the relationships between CE measures and comprehension skills assessed. This study demonstrates the usefulness of CE measures for identifying young children's possible difficulties in carrying out specific reading comprehension processes.

    The objectives of this study are to establish a comprehensive method for radiation dose estimates for the most common imaging examinations performed for research, for internal use of institutional review board (IRB) and radiation safety committees; to provide investigators with relative examination doses so that they may better assess the potential radiation effects and risks for research subjects; and to provide simplified language that investigators can use in consent documents. Nineteen common radiation-based examinations used in clinical research at our institution were identified. For each modality (CT, digital radiography, dual-energy x-ray absorptiometry, PET/CT, and nuclear medicine), a comprehensive patient-specific dosimetry method was established. Effective dose was calculated according to average population calculated doses for the following age groups: 0-1, 2-8, 9-13, 14-15, and older than 15 years. Estimated effective dose values were tabulated and posted on our institutional IRB intranet site for use by IRB and radiation safety committee members and institutional investigators. Relative examination dose levels were compared for all ages and for all examinations. A three-tiered approach to establish consent language for radiation exposure was established for research subjects receiving an effective dose less than 3 mSv, a dose between 3 and 50 mSv, and a dose greater than 50 mSv. The method to estimate effective dose was tabulated for 19 of the most common ionizing radiation examinations at our institute. These results will act as a resource to help investigators better understand the implications of radiation exposure in research and can assist investigators in protocol development and correct categorization of radiation exposure risk.

    In accordance with the US Nuclear Regulatory Commission (US NRC), Regulatory Guide 1.20, the reactor vessel internals comprehensive vibration assessment program (RVI CVAP) has been developed for an Advanced Power Reactor 1400 (APR1400). The purpose of the RVI CVAP is to verify the structural integrity of the reactor internals to flow-induced loads prior to commercial operation. The APR1400 RVI CVAP consists of four programs (analysis, measurement, inspection, and assessment). Thoughtful preparation is essential to the measurement program, because data acquisition must be performed only once. The optimized design of a vibration and stress measurement system for the RVI CVAP is essential to verify the integrity of the APR1400 RVI. We successfully designed a vibration and stress measurement system for the APR1400 RVI CVAP based on the design materials, the hydraulic and structural analysis results, and performance tests of transducers in an extreme environment. The measurement system designed in this paper will be utilized for the APR1400 RVI CVAP as part of the first construction project in Korea

    Nutritional risk is relatively common in community-dwelling older people. To objective of this study was to evaluate the effects of individual dietary counseling as part of a Comprehensive Geriatric Assessment on nutritional status among community-dwelling people aged 75 years or older. Data were obtained from a subpopulation of participants in the population-based Geriatric Multidisciplinary Strategy for the Good Care of the Elderly (GeMS) intervention study in 2004 to 2007. In the present study, the population consist 173 persons at risk of malnutrition in the year 2005 in an intervention (n=84) and control group (n=89). Nutritional status, body weight, body mass index, serum albumin were performed at the beginning of the study and at a two-year follow-up. The nutritional screening was performed using the Mini Nutritional Assessment (MNA) test. A increase in MNA scores (1.8 95% confidence interval [CI]: 0.7 to 2.0) and in serum albumin (0.8 g/L, 95% CI: 0.2 to 0.9 g/L) were a significant difference between the groups. Nutritional intervention, even dietary counseling without nutritional supplements, may improve nutritional status.

    Heavy metals do not degrade and can remain in the environment for a long time. In this study, we analyzed the effects of Cu, Cd, Pb, Zn, Hg, and As, on environmental quality, pollutant enrichment, ecological hazard, and source identification of elements in sediments using data collected from samples taken from Shuangtai tidal wetland. The comprehensive pollution indices were used to assess environmental quality; fuzzy similarity analysis and geoaccumulation index were used to analyze pollution accumulation; correlation matrix, principal component analysis, and clustering analysis were used to analyze pollution source; environmental risk index and ecological risk index were used to assess ecological risk. The results showed that the environmental quality was either clean or almost clean. Pollutant enrichment analysis showed that the four sub-regions had similar pollution-causing metals to the background values of the soil element of the Liao River Plain, which were ranked according to their similarity. Source identification showed that all the elements were correlated. Ecological hazard analysis showed that the environmental risk index in the study area was less than zero, posing a low ecological risk. Ecological risk of the six elements was as follows: As > Cd > Hg > Cu > Pb > Zn.

    The assessment of cognitive function is important in comprehensive geriatric assessment (CGA), and several standardized screening tests for dementia such as the Mini-Mental State Examination (MMSE) are available. However, it takes 5 to 20 minutes to perform the MMSE. We have developed a CGA initiative named 'Dr. Superman' which is designed to accomplish CGA within 10 minutes. In this study, we evaluated a short-form screening test for cognitive decline preceding the MMSE. The MMSE and a question on episodic memory, ("What kind of food did you have last night?") were administered to 90 elderly outpatients with various diseases. They were divided into 2 groups according to their MMSE scores: a normal group (MMSE score≥24) and an abnormal group (MMSE score≤23). Within these groups, each domain (D) (D1: time orientation, D2: place orientation, D3: immediate memory, D4: calculation, D5: recall, D6: language, and D7: spatial cognition) and episodic memory was separately scored and the sensitivity, specificity, and positive predicative value of each were calculated. Based on these data, the best combination of the domains was evaluated for practical use as an assessment tool. The MMSE scores ranged from 10 to 30, and 42 cases were classified into the normal group. High sensitivity, specificity, or positive predicative value was observed in D1, D2, D4, D5 and episodic memory categories. On the basis of the characteristics of each item in these domains in order to make a short-form assessment, a combination of "What is this year" in D1, "Serial 7's twice" in D4, and a question on episodic memory was found to be superior to other combinations (sensitivity: 93.8%; specificity: 71.4%; positive predicative value: 78.9%). Using this combination for 50 outpatients with 2 raters, it took 32 to 55 seconds to accomplish the assessment with good inter-rater reliability (κ=0.861). The combination of "What is this year?", "Serial 7's twice", and "What kind of food did you have

    Full Text Available ICDAS (the International Caries Detection and Assessment System is a new approach to the detection and classification of dental caries, starting with the stage showing the earliest visual changes. Methodology: This article describes the implementation of the ICDAS at the School of Dentistry, International Medical University, and Kuala Lumpur, Malaysia in a step-by-step systematically planned process. Beginning with the setting up of a Task Force in 2011 for the evaluation and preparation of the training resources and the running of exploratory training exercises, it finally culminated in carrying out training workshops for the entire staff and students. After the internal processes had been completed, an international expert (KE was invited to evaluate the process and conduct another workshop using the resources developed within the University, including a reference set of carious teeth. The overall time taken was one and a half years. Conclusions: The implementation of the ICDAS has been comprehensively set into motion within the context of our local curriculum and oral healthcare delivery arrangements. However, this will be an ongoing process with further quality assurance measures being required clinically together with the continuing training of new staff. Sharing this ‘framework’ of the ICDAS implementation process should considerably ease the path and reduce the time period of future implementations by other dental teaching institutions.

    For the realization of environmentally friendly, sound economic activities and the assurance of a safe and peaceful daily life for people, studies were conducted about comprehensive risk assessment and management techniques to use in dealing with chemical substances. Concerning the above-named management program, a workshop was called, where panel discussion and exchange of views and opinions were held. In the study of overseas technological trends, visits were paid to interested institutes and corporations in Denmark, Sweden, and Germany, where hearings were held over the management and manufacture of chemical substances. Concerning the control of chemical substances, surveys were conducted of the control in Japan and abroad and of the methods that businesses and other organizations followed in meeting the control. It was found that the control was being dealt with earnestly in every country and that chemical substances would stay managed under international collaborative conditions. Efforts were being positively exerted by businesses and other organizations to properly manage and reduce chemical substances and to develop and use substitutes. It was found that measures for handling chemical substances were closely knit into business management. (NEDO)

    Mitchell, Mary A.

    This study analyzed English language learner (ELL) performance on the June 2012 Biology MCAS, namely on item attributes of domain, cognitive skill, and linguistic complexity. It examined the impact of English proficiency, Latinate first language, first language orthography, and late-entry ELL status. The results indicated that English proficiency was a strong predictor of performance and that ELLs at higher levels of English proficiency overwhelmingly passed. The results further indicated that English proficiency introduced a construct-irrelevant variance on the Biology MCAS and raised validity issues for using this assessment at lower levels of English proficiency. This study also found that ELLs with a Latinate first language consistently had statistically significant lower performance. Late-entry ELL status did not predict Biology MCAS performance.

    Context The severity of Sjögren’s syndrome has been evaluated using a wide variety of clinical measures and patient-reported outcomes (PROs). This may contribute to the lack of clarity concerning the burden of Sjögren’s from the patient perspective. Objective To perform a comprehensive peer-reviewed literature analysis of the patient aspects of Sjögren’s, focusing on PROs, to investigate the complexity underlying the evaluation of the syndrome and to elucidate the discordance between the different measures. Methods We searched Embase for articles published between January 2005 and September 2015. Research articles, clinical and diagnostic reviews, and validation studies with a focus on patient aspects of Sjögren’s were selected as the primary information source. Results 157 articles met the eligibility criteria. A wide variety of assessment measures used to evaluate glandular, extraglandular and functional domains were observed. Many different, non-validated Visual Analogue Scales, with a wide range of anchor words, were used in the quantification of Sjögren’s disease burden, impeding comparisons between studies. Relatively few clinical trials of drug therapies used validated scales: European League Against Rheumatism Sjögren’s Syndrome Patient Reported Index was used most often for symptom assessment and 36 Item Short Form Survey for quality of life (QoL). Conclusion A wide range and diversity of measures are used to evaluate the patient burden of Sjögren’s; most are not validated for use in this disease. PRO endpoints, validated specifically in Sjögren’s, that demonstrate improvement are needed. These measures should focus on QoL aspects important to patients and will most likely involve gauging change in function rather than patient-reported symptoms. PMID:28955493

    Full Text Available The ladybird beetle, Coleomegilla maculata (DeGeer, is a common and abundant predator in many cropping systems. Its larvae and adults are predaceous, feeding on aphids, thrips, lepidopteran larvae and plant tissues, such as pollen. Therefore, this species is exposed to insecticidal proteins expressed in insect-resistant, genetically engineered cotton expressing Cry proteins derived from Bacillus thuringiensis (Bt. A tritrophic bioassay was conduced to evaluate the potential impact of Cry2Ab- and Cry1Ac-expressing cotton on fitness parameters of C. maculata using Bt-susceptible and -resistant larvae of Trichoplusia ni as prey. Coleomegilla maculata survival, development time, adult weight and fecundity were not different when they were fed with resistant T. ni larvae reared on either Bt or control cotton. To ensure that C. maculata were not sensitive to the tested Cry toxins independent from the plant background and to add certainty to the hazard assessment, C. maculata larvae were fed artificial diet incorporated with Cry2Ab, Cry1Ac or both at >10 times higher concentrations than in cotton tissue. Artificial diet containing E-64 was included as a positive control. No differences were detected in any life-table parameters between Cry protein-containing diet treatments and the control diet. In contrast, larvae of C. maculata fed the E-64 could not develop to the pupal stage and the 7-d larval weight was significantly negatively affected. In both feeding assays, the stability and bioactivity of Cry proteins in the food sources were confirmed by ELISA and sensitive-insect bioassays. Our results show that C. maculata is not affected by Bt cotton and is not sensitive to Cry2Ab and Cry1Ac at concentrations exceeding the levels in Bt cotton, thus demonstrating that Bt cotton will pose a negligible risk to C. maculata. More importantly, this study demonstrates a comprehensive system for assessing the risk of genetically modified plants on non

    Epidemiological studies suggested that poor sleep is a potentially novel risk factor for several health outcomes currently; however, there are no validated questionnaires that can systematically measure sleep parameters within these studies. We evaluated the reliability and validity of 17-item sleep factors questionnaire (SFQ), which was developed to comprehensively assess long-term sleep habits for the Jiujiang Breast Cancer Study (JBCS), Jiujiang, China. The participants included 100 women aged 18-74years, who were randomly selected from the JBCS project, and completed a SFQ at baseline and again 1year later, and 4 quarterly 30 consecutive days (a total of 120days) sleep diaries over this same year. Reliability was tested by comparing the 2 SFQs; validity by comparing the average measures between the SFQ and the 4 sleep diaries. Validity analysis showed moderate correlation (γ=0.41) for sleep duration with the adjusted concordance correlation coefficient (CCC adj ) of 0.54; the weighted κ statistics indicated an excellent agreement for night/shift work and sleep medication use; fair-to-moderate for sleep quality, light at night (LAN), nighttime sleeping with light on, sleep noise and nap time; slight-to-fair for sleep quality and nighttime wakings frequency. Reliability analysis showed excellent correlation for night/shift work and sleep medication use; fair-to-moderate for LAN, nighttime wakings frequency, insomnia frequency, sleep noise and nap time; but slight-to-fair for insomnia frequency and nighttime sleeping with light on; the CCC adj for sleep duration was 0.61. The SFQ showed reasonable reliability and validity for sleep assessments in most domains. Copyright © 2017 Elsevier Inc. All rights reserved.

    Yin-Qiao-Jie-Du (YQJD) tablet is a well-known non-prescription Chinese patent drug widely used for the prevention and treatment of diseases in China. However, documented studies for assessing and controlling the quality of YQJD tablet are limited. In this article, a rapid and comprehensive method for the quality assessment and control of YQJD tablets was developed, via qualitative and quantitative analysis of the major active ingredients of YQJD tablets by ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS) in combination with multivariate statistical analysis. The samples of YQJD tablets were triturated and then extracted with methanol, and the extracts were analyzed by UHPLC-QTOF-MS. A good separation was achieved within 30 min by using an Agilent RRHD SB-C18 (150 mm × 2.1mm I.D., 1.8 μm) column with a gradient elution of water (0.5% formic acid) and acetonitrile. Forty-one major chromatographic peaks were obtained, and 31 of them were identified according to the obtained data from the measurements of accurate mass, isotopic composition, and collision-induced dissociation. Among them, 21 were confirmed by the comparison of retention times, MS, and MS/MS information with those of their references. Quantitative analysis was performed based on the peak areas of extracted ion chromatograms of the exact pseudo-molecular ions (with a 0.01 Da window), and the result of method validation demonstrated that the proposed method possessed desirable specificity, linearity, precision, and accuracy. Subsequently, the method was utilized to analyze the major constituents in YQJD tablets of 18 batches produced by different manufacturers. The obtained contents of the 21 confirmed ingredients were applied for orthogonal partial-least squares to latent structures discriminant analysis (OPLS-DA). An assessment of the quality consistency and stability as well as tracing the origins of the investigated YQJD tablets

    The Hawking-Penrose theorems tell us that solutions of Einstein's equations are generally singular, in the sense of the incompleteness of causal geodesics (the paths of physical observers). These singularities might be marked by the blowup of curvature and therefore crushing tidal forces, or by the breakdown of physical determinism. Penrose has conjectured (in his `Strong Cosmic Censorship Conjecture`) that it is generically unbounded curvature that causes singularities, rather than causal breakdown. The verification that ``AVTD behavior'' (marked by the domination of time derivatives over space derivatives) is generically present in a family of solutions has proven to be a useful tool for studying model versions of Strong Cosmic Censorship in that family. I discuss some of the history of Strong Cosmic Censorship, and then discuss what is known about AVTD behavior and Strong Cosmic Censorship in families of solutions defined by varying degrees of isometry, and discuss recent results which we believe will extend this knowledge and provide new support for Strong Cosmic Censorship. I also comment on some of the recent work on ``Weak Null Singularities'', and how this relates to Strong Cosmic Censorship.

    Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical detection of strong lenses. Such a ''piggy-back'' survey might be expected even pessimistically to provide a catalogue of a few thousand new strong lenses, with the numbers dominated by systems of faint blue galaxies lensed by foreground ellipticals. After sketching out our strategy for detecting and measuring these galaxy lenses using the SNAP images, we discuss some of the scientific applications of such a large sample of gravitational lenses: in particular we comment on the partition of information between lens structure, the source population properties and cosmology. Understanding this partitioning is key to assessing strong lens cosmography's value as a cosmological probe.

    Assessment of the nutritional state is important in comprehensive geriatric assessment (CGA). Several standardized screening tests for malnutrition are available such as the Mini-Nutritional Assessment (MNA) and MNA-Short Form (MNA-SF). However, it takes more than 10 minutes to perform the MNA-SF alone. We have developed a CGA initiative named 'Dr. SUPERMAN', which is designed to accomplish CGA within 10 minutes. In this study, we evaluated a short-form screening test for malnutrition preceding the MNA. The MNA-SF, which consists of 6 items (A-F), was administered to 163 elderly outpatients (mean age: 83.4 years, 80 men) with various diseases. Using the results of the MNA-SF score (normal ≥ 12 and abnormal ≤ 11) as a gold standard, the sensitivity, specificity, and positive predictive values (PPVs) of each item were calculated and the best combination of 2 items for identifying malnutrition among the elderly outpatients was selected. According to the combination of 2 items (item B: weight loss during the last 3 months; item F: body mass index (BMI)/calf circumference (CC) in cm), they were divided into 2 groups: the normal control (NC) group (neither items B nor F) and the malnutrition/at risk (MN) group (either items B or D, or both). Findings of the clinical feature, anthropometric measurement, and nutritional biomarker between the 2 groups were examined to clarify the characteristics of each. The MNA-SF score was distributed as follows: 3-7 in 12 cases, 8-11 in 68 cases, and 12-14 in 83 cases. Based on the MNA-SF score, the combination of items B and F revealed the highest sensitivity (91.3%), specificity (63.9%), and PPV (70.9%), resulting in 103 cases in the MN group and 60 cases in the NC group. A high frequency of anorexia, living alone, hypoprealbuminemia, lymphocytopenia, and dehydration was observed in the MN group, whereas a high frequency of leg edema was observed in the NC group.

  13. "Life-like" assessment of antimicrobial surfaces by a new touch transfer assay displays strong superiority of a copper alloy compared to silver containing surfaces.

    Directory of Open Access Journals (Sweden)

    Johannes Karl-Mark Knobloch

    Full Text Available Transmission of bacteria from inanimate surfaces in healthcare associated environments is an important source of hospital acquired infections. A number of commercially available medical devices promise to fulfill antibacterial activity to reduce environmental contamination. In this study we developed a touch transfer assay modeling fingerprint transmission to investigate the antibacterial activity of surfaces, with confirmed antibacterial activity by a modified ISO 22196 (JIS Z 2801 assay to test such surfaces under more realistic conditions. Bacteria were taken up from a dry standardized primary contaminated surface (PCS with disinfected fingers or fingers covered with sterile and moistened cotton gloves. Subsequently, bacteria were transferred by pressing on secondary contaminated surfaces (SCS with or without potential antibacterial activity and the relative reduction rate was determined after 24 h. A stable transmission rate between PCS and SCS was observed using moistened sterile gloves. A copper containing alloy displayed at least a tenfold reduction of the bacterial load consistently reaching less than 2.5 cfu/cm2. In contrast, no significant reduction of bacterial contamination by silver containing surfaces and matured pure silver was observed in the touch transfer assay. With the touch transfer assay we successfully established a new reproducible method modeling cross contamination. Using the new method we were able to demonstrate that several surfaces with confirmed antimicrobial activity in a modified ISO 22196 (JIS Z 2801 assay lacked effectiveness under defined ambient conditions. This data indicate that liquid based assays like the ISO 22196 should be critically reviewed before claiming antibacterial activity for surfaces in the setting of contamination of dry surfaces by contact to the human skin. We suggest the newly developed touch transfer assay as a new additional tool for the assessment of potential antimicrobial surfaces

    This paper shows that the counterexamples proposed by Strong in 2008 in the Journal of Medical Ethics to Marquis's argument against abortion fail. Strong's basic idea is that there are cases--for example, terminally ill patients--where killing an adult human being is prima facie seriously morally......'s scenarios have some valuable future or admitted that killing them is not seriously morally wrong. Finally, if "valuable future" is interpreted as referring to objective standards, one ends up with implausible and unpalatable moral claims....

    To assess the validity of the American Board of Orthodontics Discrepancy Index (ABO-DI) and Peer Assessment Rating (PAR) Index in evaluating malocclusion severity in Chinese orthodontic patients. A stratified random sample of 120 orthodontic patients based on Angle classification was collected from six university orthodontic centres. Sixty-nine orthodontists rated malocclusion severity on a five-point scale by assessing a full set of pre-treatment records for each case and listed reasons for their decision. Their judgement was then compared with ABO-DI and PAR scores determined by three calibrated examiners. Excellent interexaminer reliability of clinician judgement, ABO-DI and PAR index was demonstrated by the Intraclass Correlation Coefficient (rho= 0.995, 0.990 and 0.964, respectively). Both the ABO-DI and US-PAR index showed good correlation with clinician judgement (r=.700 and r=.707, respectively). There was variability among the different Angle classifications: the ABO-DI showed the highest correlation with clinician judgement in Class II patients (r=.780), whereas the US-PAR index showed the highest correlation with clinician judgement in Class III patients (r=.710). Both indices demonstrated the lowest correlations with clinician judgement in Class I patients. With strong interexaminer agreement, the panel consensus was used for validating the ABO-DI and US-PAR index for malocclusion severity. Overall, the ABO-DI and US-PAR index were reliable for measuring malocclusion severity with significantly variable weightings for different Angle classifications. Further modification of the indices for different Angle classification may be indicated. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    NABIR funding at the University of Tennessee Center for Biomarker Analysis (CBA) has led to several key contributions to the investigation of bioremediation of metals and radionuclides. This lab has played an integral part in assessing microbial communities at the field scale at the ORNL FRC (Istok et al., 2004) and two UMTRA sites (Anderson et al., 2003, Chang et al., 2001). Our work over the period of the grant has resulted in 42-peer reviewed publications, 62 presentations (14 of which were international), and one patent pending. Currently CBA has 2 papers in press. The main objectives relating to the field portion of this program were to provide comprehensive biomarker analysis for NABIR collaborators to enhance the understanding of microbial geo-bioprocesses involved in the effective immobilization of metals (We have worked with and published or currently are publishing with 10 groups of NAIBR investigators). The laboratory portion of our research centered on methods development and has led to three major innovations that could result in a systematic way of evaluating sites for potential bioremediation. The first of these is the development of an in situ sampling device (Peacock et al., 2004, Anderson et al., 2003, Istok et al., 2004) for the collection and concentration of microbial biomass. The second is the development of expanded lipid analysis based on the significantly greater sensitivity and selectivity of the LC/MS/MS that allows the analysis of respiratory quinones, diglycerides, sterols, intact phospholipids, poly-hydroxyalkonates, and potentially archaeol, and caldarchaeols from archea. These new analyses are accomplished more rapidly and with increased sensitivities and resolution than in the past (Lytle et al., 2000a, 2000b, 2001a, Geyer et al., 2004). The third advance is the coupling of lipid analysis with 13C enrichment experiments (Lytle et al., 2001b, Geyer et al. 2005). With this technique it is now possible to follow the active portion of

  1. Strong Electroweak Symmetry Breaking

    Grinstein, Benjamin

    2011-01-01

    Models of spontaneous breaking of electroweak symmetry by a strong interaction do not have fine tuning/hierarchy problem. They are conceptually elegant and use the only mechanism of spontaneous breaking of a gauge symmetry that is known to occur in nature. The simplest model, minimal technicolor with extended technicolor interactions, is appealing because one can calculate by scaling up from QCD. But it is ruled out on many counts: inappropriately low quark and lepton masses (or excessive FCNC), bad electroweak data fits, light scalar and vector states, etc. However, nature may not choose the minimal model and then we are stuck: except possibly through lattice simulations, we are unable to compute and test the models. In the LHC era it therefore makes sense to abandon specific models (of strong EW breaking) and concentrate on generic features that may indicate discovery. The Technicolor Straw Man is not a model but a parametrized search strategy inspired by a remarkable generic feature of walking technicolor,...

  2. Plasmons in strong superconductors

    2011-01-01

    We present a study of the possible plasmon excitations that can occur in systems where strong superconductivity is present. In these systems the plasmon energy is comparable to or smaller than the pairing gap. As a prototype of these systems we consider the proton component of Neutron Star matter just below the crust when electron screening is not taken into account. For the realistic case we consider in detail the different aspects of the elementary excitations when the proton, electron components are considered within the Random-Phase Approximation generalized to the superfluid case, while the influence of the neutron component is considered only at qualitative level. Electron screening plays a major role in modifying the proton spectrum and spectral function. At the same time the electron plasmon is strongly modified and damped by the indirect coupling with the superfluid proton component, even at moderately low values of the gap. The excitation spectrum shows the interplay of the different components and their relevance for each excitation modes. The results are relevant for neutrino physics and thermodynamical processes in neutron stars. If electron screening is neglected, the spectral properties of the proton component show some resemblance with the physical situation in high-T c superconductors, and we briefly discuss similarities and differences in this connection. In a general prospect, the results of the study emphasize the role of Coulomb interaction in strong superconductors.

    Standard path-integral techniques such as instanton calculations give good answers for weak-coupling problems, but become unreliable for strong-coupling. Here we consider a method of replacing the original potential by a suitably chosen harmonic oscillator potential. Physically this is motivated by the fact that potential barriers below the level of the ground-state energy of a quantum-mechanical system have little effect. Numerically, results are good, both for quantum-mechanical problems and for massive phi 4 field theory in 1 + 1 dimensions. 9 references, 6 figures

    With an assumed weak multiplet structure for bosonic hadrons, which is consistent with the ΔI = 1/2 rule, it is shown that the strong interaction effective hamiltonian is compatible with the weak SU(2) x U(1) gauge transformation. Especially the rho-meson transforms as a triplet under SU(2)sub(w), and this is the origin of the rho-photon analogy. It is also shown that the existence of the non-vanishing Cabibbo angle is a necessary condition for the absence of the exotic hadrons. (orig.)

  6. Strong Coupling Holography

    We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4+d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this effect for orbifold planes, as well as for the solitonic branes and string theoretic D-branes. In all cases the emergence of a 4D strong coupling scale from bulk holography is a persistent phenomenon. The effect turns out to be insensitive even to such extreme deformations of the brane action that seemingly shield 4D theory from the bulk gravity effects. A well understood example of such deformation is given by large 4D Einstein term in the 3-brane action, which is known to suppress the strength of 5D gravity at short distances and change the 5D Newton's law into the four-dimensional one. Nevertheless, we observe that the ...

    2007-05-15

    The defence to obtain the 'Habilitation a Diriger des Recherches' is a synthesis of the research work performed since the end of my Ph D. thesis in 1997. This synthesis covers the two years as post doctoral researcher at the Bureau d'Evaluation des Risques Sismiques at the Institut de Protection (BERSSIN), and the seven consecutive years as seismologist and head of the BERSSIN team. This work and the research project are presented in the framework of the seismic risk topic, and particularly with respect to the seismic hazard assessment. Seismic risk combines seismic hazard and vulnerability. Vulnerability combines the strength of building structures and the human and economical consequences in case of structural failure. Seismic hazard is usually defined in terms of plausible seismic motion (soil acceleration or velocity) in a site for a given time period. Either for the regulatory context or the structural specificity (conventional structure or high risk construction), seismic hazard assessment needs: to identify and locate the seismic sources (zones or faults), to characterize their activity, to evaluate the seismic motion to which the structure has to resist (including the site effects). I specialized in the field of numerical strong-motion prediction using high frequency seismic sources modelling and forming part of the IRSN allowed me to rapidly working on the different tasks of seismic hazard assessment. Thanks to the expertise practice and the participation to the regulation evolution (nuclear power plants, conventional and chemical structures), I have been able to work on empirical strong-motion prediction, including site effects. Specific questions related to the interface between seismologists and structural engineers are also presented, especially the quantification of uncertainties. This is part of the research work initiated to improve the selection of the input ground motion in designing or verifying the stability of structures. (author)

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions. Following ALEPH he tur...

  14. Stirring Strongly Coupled Plasma

    Fadafan, Kazem Bitaghsir; Rajagopal, Krishna; Wiedemann, Urs Achim

    2009-01-01

    We determine the energy it takes to move a test quark along a circle of radius L with angular frequency w through the strongly coupled plasma of N=4 supersymmetric Yang-Mills (SYM) theory. We find that for most values of L and w the energy deposited by stirring the plasma in this way is governed either by the drag force acting on a test quark moving through the plasma in a straight line with speed v=Lw or by the energy radiated by a quark in circular motion in the absence of any plasma, whichever is larger. There is a continuous crossover from the drag-dominated regime to the radiation-dominated regime. In the crossover regime we find evidence for significant destructive interference between energy loss due to drag and that due to radiation as if in vacuum. The rotating quark thus serves as a model system in which the relative strength of, and interplay between, two different mechanisms of parton energy loss is accessible via a controlled classical gravity calculation. We close by speculating on the implicati...

    International Nuclear Information System (INIS)

    Volkas, R.R.; Foot, R.; He, X.; Joshi, G.C.

    1989-01-01

    The universal QCD color theory is extended to an SU(3) 1 direct product SU(3) 2 direct product SU(3) 3 gauge theory, where quarks of the ith generation transform as triplets under SU(3)/sub i/ and singlets under the other two factors. The usual color group is then identified with the diagonal subgroup, which remains exact after symmetry breaking. The gauge bosons associated with the 16 broken generators then form two massive octets under ordinary color. The interactions between quarks and these heavy gluonlike particles are explicitly nonuniversal and thus an exploration of their physical implications allows us to shed light on the fundamental issue of strong-interaction universality. Nonuniversality and weak flavor mixing are shown to generate heavy-gluon-induced flavor-changing neutral currents. The phenomenology of these processes is studied, as they provide the major experimental constraint on the extended theory. Three symmetry-breaking scenarios are presented. The first has color breaking occurring at the weak scale, while the second and third divorce the two scales. The third model has the interesting feature of radiatively induced off-diagonal Kobayashi-Maskawa matrix elements

    1999-05-01

    This thesis contains the main results of the research topics I have pursued during the my PhD studies at the University of Innsbruck and partly in collaboration with the Institut d' Optique in Orsay, France. It is divided into three parts. The first and largest part discusses the possibility of using strong standing waves as a tool to cool and trap neutral atoms in optical cavities. This is very important in the field of nonlinear optics where several successful experiments with cold atoms in cavities have been performed recently. A discussion of the optical parametric oscillator in a regime where the nonlinearity dominates the evolution is the topic of the second part. We investigated mainly the statistical properties of the cavity output of the three interactive cavity modes. Very recently a system has been proposed which promises fantastic properties. It should exhibit a giant Kerr nonlinearity with negligible absorption thus leading to a photonic turnstile device based on cold atoms in cavity. We have shown that this model suffers from overly simplistic assumptions and developed several more comprehensive approaches to study the behavior of this system. Apart from the division into three parts of different contents the thesis is divided into publications, supplements and invisible stuff. The intention of the supplements is to reach researchers which work in related areas and provide them with more detailed information about the concepts and the numerical tools we used. It is written especially for diploma and PhD students to give them a chance to use the third part of our work which is actually the largest one.

    Full Text Available La comprensión narrativa es una habilidad fundamental en la alfabetización infantil, poco atendida por investigadores y educadores por las dificultades para comprenderla y medirla, sobre todo a edades tempranas. Se reportan resultados de un estudio cuyo objetivo fue elaborar y validar un instrumento para la medición de la comprensión narrativa en niños en edad preescolar. Participaron 117 niños y niñas chilenos entre 3 años 6 meses y 5 años 1 mes de edad, pertenecientes a jardines infantiles de la Región Metropolitana. Se encontró evidencia que apoya la confiabilidad y la validez concurrente del instrumento, de fácil y rápida aplicación y codificación. Se discuten las implicancias de contar con un instrumento para medir comprensión narrativa que sea adecuado a la población preescolar chilena, así como estudios futuros necesarios para mejorar el instrumento.Narrative comprehension is a fundamental ability for children's literacy development that has been largely ignored by researchers and educators, due to the difficulties in understanding and measuring it, particularly in the early ages. The results of a study, whose goal was to construct and validate an instrument to measure narrative comprehension in preschool age children, are presented. Participants were 117 Chilean children aged 3 years and 6 months to 5 years and 1 month. Evidence was found to support the reliability and concurrent validity of the instrument, which is simple and quick to administer and code. The implications of having an instrument to measure narrative comprehension that is adequate for the Chilean preschool population are discussed, as are future studies to improve the instrument.

    2012-01-01

    Full Text Available Canadian Aboriginals, like others globally, suffer from disproportionately high rates of diabetes. A comprehensive evidence-based approach was therefore developed to study potential antidiabetic medicinal plants stemming from Canadian Aboriginal Traditional Medicine to provide culturally adapted complementary and alternative treatment options. Key elements of pathophysiology of diabetes and of related contemporary drug therapy are presented to highlight relevant cellular and molecular targets for medicinal plants. Potential antidiabetic plants were identified using a novel ethnobotanical method based on a set of diabetes symptoms. The most promising species were screened for primary (glucose-lowering and secondary (toxicity, drug interactions, complications antidiabetic activity by using a comprehensive platform of in vitro cell-based and cell-free bioassays. The most active species were studied further for their mechanism of action and their active principles identified though bioassay-guided fractionation. Biological activity of key species was confirmed in animal models of diabetes. These in vitro and in vivo findings are the basis for evidence-based prioritization of antidiabetic plants. In parallel, plants were also prioritized by Cree Elders and healers according to their Traditional Medicine paradigm. This case study highlights the convergence of modern science and Traditional Medicine while providing a model that can be adapted to other Aboriginal realities worldwide.

    2015-04-01

    We apply a social-ecological interpretive framework to understanding relationships among patient privacy, psychological health, social stigma, and continuity in care in the HIV treatment cascade in the rural southeastern US. This research was conducted as part of the 2013 comprehensive needs assessment for the Northeast Georgia Ryan White Consortium using an anthropologically informed mixed-methods design, and a deductive-inductive approach to thematic analysis of qualitative data obtained in interviews and focus groups with service providers and service utilizers. Our comprehensive needs assessment yielded two key components. First, we identified salient phenomena influencing introduction to, retention among, and satisfaction of patients in the Ryan White-coordinated treatment cascade in NE-GA. Second, we formulated actionable recommendations around leverage points identified in the current district-wide system of care. Results highlight spatial, institutional, and interpersonal aspects of the system of care that intersect around issues of patient privacy, psychological health, and social stigma. These intersections constitute pathways by which persons living with HIV are exposed to stigma and other negative social signals regarding their health status without sufficient access to behavioral health services. These negative issues, in turn, can erect significant barriers to long-term continuity in care. Copyright © 2015 Elsevier Ltd. All rights reserved.

    1980-08-01

    Initial plans for research of the carbon dioxide (CO/sub 2/) and climate issue were prepared in 1978 and were reviewed extensively at that time by federal agencies and members of the scientific community. Since then the plans have been used to guide early phases of the Department of Energy's and the nation's efforts related to this issue. This document represents a revision of the 1978 plan to (a) reflect recent ideas and strategies for carbon cycle research, and (b) expand the scope of research on climatic responses to increasing atmospheric concentrations of CO/sub 2/. The revised plan takes into account a number of investigations already being supported by various agencies, and it attempts to build on or add to existing research where there is a crucial need for information directly related to the CO/sub 2/ issue. It should be recognized that this document is the first section of a comprehensive plan on the overall consequences of increasing concentrations of CO/sub 2/, and includes guidelines for research on the Global Carbon Cycle and Climatic Effects of Increasing CO/sub 2/.

    Full Text Available The idea of a circular economy (CE, which differs from traditional linear economy with a high consumption of natural resources and pollution, has captured much interest and attention. This paper uses a CE system of coal power and cement in Kongtong District, Pingliang City, Gansu Province, China as a case study to analyze the comprehensive effects of CE paradigm. Our simulation results, based on system dynamics (SD modeling, infer that the transformation of manufacturing towards a CE system can prominently help coal power and cement enterprises reduce waste emission and increase economic profits. Through solid waste exchanges, a power plant can achieve over RMB 80 million of additional revenue per year at the highest level. CE also contributes to the reduction of regional pollution, saves mineral resources, and improves the atmospheric environment, an accumulated total of 14.11 million t of natural gypsum and 22.67 million t of coal can be saved. This sets a promising example for coal power and cement plants worldwide. Effective regulatory measures and further optimization towards a circular economy system are essential in maintaining the stable development of a CE system due to the risk of surplus production of upstream industries and other defects.

    Full Text Available Diabetic foot ulcers (DFU are increasingly prevalent, and associated with significant morbidity, mortality, and cost. An interprofessional approach to DFU management is critical given the etiological complexity involved. This study aimed to assess the impact of an interprofessional team approach on DFU diagnosis and management for a cohort of patients receiving treatment in an Ontario Canada home care setting.A retrospective cohort study of patients attending a large regional Community Care Access Centre (CCAC between February 11, 2013-September 30, 2014 was conducted. Following CCAC referral, patients were assessed by an interprofessional team at the Toronto Regional Wound Healing Centre (TRWHC. Those aged > 18 years with a DFU of > 6 weeks duration were included. The primary outcome was the precision of the initial diagnosis relating to DFU etiology (i.e. neuropathic, ischemic or mixed etiology.

    A fixed-dose combination of atorvastatin and aspirin is widely used for the treatment of myocardial infarction. The present work describes a comprehensive study of the stress degradation behavior of atorvastatin and aspirin alone as well as in combination of 1:1 and 1:7.5 ratios, respectively, as per ICH guidelines. The degradation products of aspirin as well as atorvastatin were successfully separated by a developed simple, selective, and precise stability-indicating reversed-phase HPLC method. Chromatographic separation was achieved on the Phenomenex Luna analytical column, 150 mm × 4.6 mm, 5μm. The mobile phase consisted of 0.1% glacial acetic acid in water and acetonitrile in the ratio of 50:50 v/v at a flow rate of 1.0 ml/min. UV detection was performed at 246 nm. The extent of degradation was significantly influenced when both of the drugs were present in combination. Stress degradation behavior of atorvastatin was highly influenced by aspirin under acid hydrolysis, thermal degradation, and oxidative stress conditions. Similarly, the stress degradation behavior of aspirin was affected by atorvastatin especially under neutral hydrolysis, thermal degradation, and oxidative stress conditions. Additionally, the combination ratio of aspirin and atorvastatin also influenced the percentage degradation of each other. A mixture of aspirin and atorvastatin was also analyzed after a one-month stability study at 40 °C and 75% RH. All the results indicate chemical incompatibility of both aspirin and atorvastatin if present in combination.

    2017-12-26

    This study aims to develop assessment indicators of health education and promotion for non-communicable disease (NCD) demonstration districts in China and to identify significant factors associated with NCD health education and promotion work. Three complementary techniques were used to conduct this study in Hunan Province, China, between late 2013 and 2015. The Delphi technique was used to develop weighted assessment indicators, followed by the rank sum ratio (RSR) to normalise the weights through rank conversion. Lastly, the technique for order of preference by similarity to ideal solution was conducted to assess five randomly selected NCD demonstration districts representing five different orientations in the province. A total of 24 assessment indicators were constructed covering the following sections: organisational management, fund support, personnel supplies, health education and promotion, people's awareness of NCDs, management and control of patients with NCD, satisfaction with health education and promotion and health literacy of residents. Five districts were selected as samples for evaluation (Furong District, Ziyang District, Shaodong County, Shuangfeng County and Luxi County). Performance varied among the sites, with Furong District greatly surpassing the other sites, especially in fund support, media promotion, technical support for publicity materials, community promotion and supportive environment supplies. The latter four factors were also much greater in the second-ranked Luxi County site than those in the other sites (except Furong District). There were gaps in health education and promotion work in NCD demonstration districts in Hunan Province. The districts that performed better had obvious advantages in fund support, media promotion, technical support, community promotion and supportive environment supplies. Our study provided both a methodological reference and an assessment indicator framework for similar future studies. © Article author

  16. Quotient-Comprehension Chains

    Directory of Open Access Journals (Sweden)

    Kenta Cho

    2015-11-01

    Full Text Available Quotients and comprehension are fundamental mathematical constructions that can be described via adjunctions in categorical logic. This paper reveals that quotients and comprehension are related to measurement, not only in quantum logic, but also in probabilistic and classical logic. This relation is presented by a long series of examples, some of them easy, and some also highly non-trivial (esp. for von Neumann algebras. We have not yet identified a unifying theory. Nevertheless, the paper contributes towards such a theory by introducing the new quotient-and-comprehension perspective on measurement instruments, and by describing the examples on which such a theory should be built.

    Pahn, Gregor; Skornitzke, Stephan; Schlemmer, Hans-Peter; Kauczor, Hans-Ulrich; Stiller, Wolfram

    2016-01-01

    Based on the guidelines from "Report 87: Radiation Dose and Image-quality Assessment in Computed Tomography" of the International Commission on Radiation Units and Measurements (ICRU), a software framework for automated quantitative image quality analysis was developed and its usability for a variety of scientific questions demonstrated. The extendable framework currently implements the calculation of the recommended Fourier image quality (IQ) metrics modulation transfer function (MTF) and noise-power spectrum (NPS), and additional IQ quantities such as noise magnitude, CT number accuracy, uniformity across the field-of-view, contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR) of simulated lesions for a commercially available cone-beam phantom. Sample image data were acquired with different scan and reconstruction settings on CT systems from different manufacturers. Spatial resolution is analyzed in terms of edge-spread function, line-spread-function, and MTF. 3D NPS is calculated according to ICRU Report 87, and condensed to 2D and radially averaged 1D representations. Noise magnitude, CT numbers, and uniformity of these quantities are assessed on large samples of ROIs. Low-contrast resolution (CNR, SNR) is quantitatively evaluated as a function of lesion contrast and diameter. Simultaneous automated processing of several image datasets allows for straightforward comparative assessment. The presented framework enables systematic, reproducible, automated and time-efficient quantitative IQ analysis. Consistent application of the ICRU guidelines facilitates standardization of quantitative assessment not only for routine quality assurance, but for a number of research questions, e.g. the comparison of different scanner models or acquisition protocols, and the evaluation of new technology or reconstruction methods.

    Purpose: To evaluate comprehensively the effect of a radiotherapy boost on breast cosmetic outcomes after 5 years in patients treated with breast-conserving surgery. Methods: The St. George and Wollongong trial (NCT00138814) randomized 688 patients with histologically proven Tis-2, N 0–1, M0 carcinoma to the control arm of 50 Gy in 25 fractions (342 patients) and the boost arm of 45 Gy in 25 fractions to the whole breast followed by a 16 Gy in 8 fraction electron boost (346 patients). Five-year cosmetic outcomes were assessed by a panel subjectively in 385 patients and objectively using pBRA (relative breast retraction assessment). A subset of patients also had absolute BRA measurements. Clinician assessment and patient self-assessment of overall cosmetic and specific items as well as computer BCCT.core analysis were also performed. Results: The boost arm had improved cosmetic overall outcomes as scored by the panel and BCCT.core software with 79% (p = 0.016) and 81% (p = 0.004) excellent/good cosmesis respectively compared with 68% in no-boost arm. The boost arm also had lower pBRA and BRA values with a mean difference of 0.60 and 1.82 mm, respectively, but was not statistically significant. There was a very high proportion of overall excellent/good cosmetic outcome in 95% and 93% in the boost and no–boost arms using patient self-assessment. However, no difference in overall and specific items scored by clinician assessment and patient self-assessment was found. Conclusion: The results show the negative cosmetic effect of a 16-Gy boost is offset by a lower whole-breast dose of 45 Gy.

  4. Strong CP, flavor, and twisted split fermions

    International Nuclear Information System (INIS)

    Harnik, Roni; Perez, Gilad; Schwartz, Matthew D.; Shirman, Yuri

    2005-01-01

    We present a natural solution to the strong CP problem in the context of split fermions. By assuming CP is spontaneously broken in the bulk, a weak CKM phase is created in the standard model due to a twisting in flavor space of the bulk fermion wavefunctions. But the strong CP phase remains zero, being essentially protected by parity in the bulk and CP on the branes. As always in models of spontaneous CP breaking, radiative corrections to theta bar from the standard model are tiny, but even higher dimension operators are not that dangerous. The twisting phenomenon was recently shown to be generic, and not to interfere with the way that split fermions naturally weaves small numbers into the standard model. It follows that out approach to strong CP is compatible with flavor, and we sketch a comprehensive model. We also look at deconstructed version of this setup which provides a viable 4D model of spontaneous CP breaking which is not in the Nelson-Barr class. (author)

  5. Transport phenomena in strongly correlated Fermi liquids

    Energy Technology Data Exchange (ETDEWEB)

    Kontani, Hiroshi [Nagoya Univ., Aichi (Japan). Dept. of Physics

    2013-03-01

    Comprehensive overview. Written by an expert of this topic. Provides the reader with current developments in the field. In conventional metals, various transport coefficients are scaled according to the quasiparticle relaxation time, {tau}, which implies that the relaxation time approximation (RTA) holds well. However, such a simple scaling does not hold in many strongly correlated electron systems, reflecting their unique electronic states. The most famous example would be cuprate high-Tc superconductors (HTSCs), where almost all the transport coefficients exhibit a significant deviation from the RTA results. To better understand the origin of this discrepancy, we develop a method for calculating various transport coefficients beyond the RTA by employing field theoretical techniques. Near the magnetic quantum critical point, the current vertex correction (CVC), which describes the electron-electron scattering beyond the relaxation time approximation, gives rise to various anomalous transport phenomena. We explain anomalous transport phenomena in cuprate HTSCs and other metals near their magnetic or orbital quantum critical point using a uniform approach. We also discuss spin related transport phenomena in strongly correlated systems. In many d- and f-electron systems, the spin current induced by the spin Hall effect is considerably greater because of the orbital degrees of freedom. This fact attracts much attention due to its potential application in spintronics. We discuss various novel charge, spin and heat transport phenomena in strongly correlated metals.

  8. Climate Benefits of Potential Avoided Emissions from Forest Conversion Diminished by Albedo Warming: Comprehensive, Data-Driven Assessment for the US and Beyond

    Science.gov (United States)

    Williams, C. A.; Gu, H.; Jiao, T.

    2017-12-01

    Avoided deforestation is a leading pathway for climate change mitigation, featuring prominently in many country's Intended Nationally Determined Contributions, but its climate benefits remain contested, in part because of reports of large offsetting effects in some regions of the world. It is well known that avoiding forest to non-forest conversion prevents forest carbon release, and sustains forest carbon uptake, but also increases albedo thus diminishing the potency of this mitigation strategy. While the mechanisms are known, their relative importance and the resulting climate benefit remain unclear. This is in part due to a lack of quantitative assessments documenting geographic variation in rates of forest conversion, associated carbon emissions, resulting radiative forcing, and the magnitude of simultaneous albedo offsets. This study (i) quantifies the current rate of forest conversion and carbon release in the United States with Landsat remote sensing and a carbon assessment framework, and (ii) compares this to quantitative estimates of the radiative forcing from the corresponding albedo change. Albedo radiative forcing is assessed with a recently-generated, global atlas of land-cover-specific albedos derived from a fusion of MODIS and Landsat reflectances, combined with snow cover and solar radiation datasets. We document the degree to which albedo warming offsets carbon cooling from contemporary forest conversions taking place in different regions of the United States and identify the underlying drivers of spatial variability. We then extend this to other regions of the world where forests are under threat and where avoided deforestation is viewed as a primary tool for climate mitigation. Results shed light on the, at times contentious, debate about the efficacy of forest protection as a mitigation mechanism.

    Previous studies have shown distinct models of cardiac adaptations to the training in master athletes and different effects of endurance and strength-training on cardiovascular function. We attempted to assess left-ventricular (LV) function, aortic (Ao) function, and right-ventricular (RV) function in athletes with different forms of training by using three-dimensional (3D) echocardiography, tissue Doppler imaging (TDI) and speckle-tracking imaging (STI). We examined 35 male marathon runners (endurance-trained athletes, ETA), 35 powerlifting athletes (strength-trained athletes, STA), 35 martial arts athletes (mixed-trained athletes, MTA), and 35 sedentary untrained healthy men (controls, CTR). Two-dimensional and three-dimensional echocardiography were performed for the assessment of LV and RV systolic/diastolic function. LV and RV longitudinal strain (LS) and LV torsion (LVtor) were determined using STI (EchoPAC BT11, GE-Ultrasound). Maximum velocity of systolic wall expansion peaks (AoSvel) was determined using TDI. ETA experienced LV eccentric hypertrophy with increased 3D LV end-diastolic volume and mass and significant increase in peak systolic apical rotation and LVtor. In all groups of athletes, RV-LS was reduced at rest and improved after exercise. AoSvel was significantly increased in ETA and MTA and significantly decreased in STA compared with CTR. There were good correlations between LV remodelling and aortic stiffness values. Multivariate analysis showed aortic wall velocities to be independently related to LV mass index. In strength-trained, endurance-trained, and mixed-trained athletes, ventricular and vascular response assessed by 3DE, TDI, and STI underlies different adaptations of LV, RV, and aortic indexes.

    Snow samples from the territory of the Setun River Valley Wildlife Sanctuary are analyzed for the content of rare-earth elements, heavy metals, and other hazardous elements by the inductively coupled plasma mass-spectrometry method. The changes in the concentrations of rare-earth elements, Pt, Pd, and indicator ratios of elements in the solid fractions of snow are revealed. A trend toward a decrease in the content of several elements northeastward of the Moscow Ring Road (MRR) is established. The level of seasonal atmospheric contamination of the area under study is assessed, and a possible source is identified.

    The calculation decides the integrity of the safety latch that will hold the strong-back to the pump during lifting. The safety latch will be welded to the strong-back and will latch to a 1.5-in. dia cantilever rod welded to the pump baseplate. The static and dynamic analysis shows that the safety latch will hold the strong-back to the pump if the friction clamps fail and the pump become free from the strong-back. Thus, the safety latch will meet the requirements of the Lifting and Rigging Manual for under the hook lifting for static loading; it can withstand shock loads from the strong-back falling 0.25 inch

    Multidisciplinary care of prostate cancer is increasingly offered in specialised cancer centres. It requires the optimisation of medical and operational processes and the integration of the different medical and non-medical stakeholders. To develop a standardised operational process assessment tool basing on the capability maturity model integration (CMMI) able to implement multidisciplinary care and improve process quality and efficiency. Information for model development was derived from medical experts, clinical guidelines, best practice elements of renowned cancer centres, and scientific literature. Data were organised in a hierarchically structured model, consisting of 5 categories, 30 key process areas, 172 requirements, and more than 1500 criteria. Compliance with requirements was assessed through structured on-site surveys covering all relevant clinical and management processes. Comparison with best practice standards allowed to recommend improvements. 'Act On Oncology'(AoO) was applied in a pilot study on a prostate cancer unit in Europe. Several best practice elements such as multidisciplinary clinics or advanced organisational measures for patient scheduling were observed. Substantial opportunities were found in other areas such as centre management and infrastructure. As first improvements the evaluated centre administration described and formalised the organisation of the prostate cancer unit with defined personnel assignments and clinical activities and a formal agreement is being worked on to have structured access to First-Aid Posts. In the pilot study, the AoO approach was feasible to identify opportunities for process improvements. Measures were derived that might increase the operational process quality and efficiency.

    2010-01-01

    We examined latitudinal variation in adult and larval heat tolerance in Drosophila melanogaster from eastern Australia. Adults were assessed using static and ramping assays. Basal and hardened static heat knockdown time showed significant linear clines; heat tolerance increased towards the tropics......, particularly for hardened flies, suggesting that tropical populations have a greater hardening response. A similar pattern was evident for ramping heat knockdown time at 0.06 °C min-1 increase. There was no cline for ramping heat knockdown temperature (CTmax) at 0.1 °C min-1 increase. Acute (static) heat...... resistance depend on assay methods. Genetic correlations in thermotolerance across life stages and evolutionary potential for critical thermal limits should be the focus of future studies....

  17. Sediment quality of the SW coastal Laizhou Bay, Bohai Sea, China: a comprehensive assessment based on the analysis of heavy metals.

    Xuelu Gao

    Full Text Available Historically, the Bohai Sea is one of the most important fishing grounds in China. Yet, surrounded by one of the biggest economic rims of China, its ecological functions have been declining rapidly in recent two decades under the heavy anthropogenic impacts. The Laizhou Bay is the smallest one of the three main bays in the Bohai Sea. Owing to the rich brine deposits, chemical industries using brine as raw materials are booming in the southern coast of the Laizhou Bay, the scale of which ranks as the largest one in China. In order to monitor and assess the environmental quality, surface sediments were collected from the coastal waters of southwestern Laizhou Bay and the rivers it connects with during summer and autumn in 2012, and analyzed for heavy metals. Several widely adopted methods were used in the overall assessment of heavy metal pollution status and potential ecological risks in these sediments, and the data were analyzed to infer the main sources of the pollutants. The results showed that the remarkably high concentrations of heavy metals were almost all recorded in a small number of riverine sites. Cr, Cu, Ni and Zn were the main environmental threat according to the sediment quality guidelines. The marine area was generally in good condition with no or low risk from the studied metals and adverse effects on biota could hardly occur. Natural sources dominated the concentrations and distributions of Cu, Ni, Pb and Zn in the marine area. Our results indicated that heavy metal pollution was not a main cause of the ecological degradation of the Laizhou Bay at present.

    The Historic Centre of Krakow is on the UNESCO World Heritage List and includes the Main Market Square, which is surrounded by the historical Planty Park. Soils in the Planty Park are an example of a green area in an urban environment that is particularly exposed to heavy metal-rich pollution. To assess the relative content of heavy metals and evaluate the sources of the contamination, pollution indices were used: Enrichment Factor (EF), Geoaccumulation Index (I geo ), Nemerow Pollution Index (PI Nemerow ), Potential Ecological Risk (RI), and Contamination Security Index (CSI). Pollution indices were calculated on the base of both reference and local geochemical backgrounds. Sources of heavy metals in soils of Planty Park are related to its historic role as a metallurgy centre, as well as the more recent urban and industrial development of Krakow centre and neighbouring areas. It is concluded that increased accumulation of heavy metals is an effect of growing numbers of emission sources. The variation of each element may not unambiguously reflect the natural or anthropogenic effect on the Planty Park soil cover. In general, the present and historical emission of pollutants and heavy metal-rich contamination has led to a mixed origin of Cd, Cu, Pb, and Zn. Moreover, it can be assumed that the content of Cr and Ni is derived from natural sources. Furthermore, a comparison of the quality of the Planty Park topsoil with the heavy metal content assessment in other urban parks in the world has been presented. Copyright © 2017 Elsevier Ltd.

    Titanium (Ti) is a strong silver-gray metal that is highly resistant to corrosion and is chemically inert. It is as strong as steel but 45 percent lighter, and it is twice as strong as aluminum but only 60 percent heavier. Titanium dioxide (TiO2) has a very high refractive index, which means that it has high light-scattering ability. As a result, TiO2 imparts whiteness, opacity, and brightness to many products. ...Because of the unique physical properties of titanium metal and the whiteness provided by TiO2, titanium is now used widely in modern industrial societies.

    Full Text Available Roots, stems, leaves, and flowers of Longdan (Gentiana rigescens Franch. ex Hemsl were collected from six geographic origins of Yunnan Province (n = 240 to implement the quality assessment based on contents of gentiopicroside, loganic acid, sweroside and swertiamarin and chemical profile using HPLC-DAD and FTIR method combined with principal component analysis (PCA. The content of gentiopicroside (major iridoid glycoside was the highest in G. rigescens, regardless of tissue and geographic origin. The level of swertiamarin was the lowest, even unable to be detected in samples from Kunming and Qujing. Significant correlations (p < 0.05 between gentiopicroside, loganic acid, sweroside, and swertiamarin were found at inter- or intra-tissues, which were highly depended on geographic origins, indicating the influence of environmental conditions on the conversion and transport of secondary metabolites in G. rigescens. Furthermore, samples were reasonably classified as three clusters along large producing areas where have similar climate conditions, characterized by carbohydrates, phenols, benzoates, terpenoids, aliphatic alcohols, aromatic hydrocarbons, and so forth. The present work provided global information on the chemical profile and contents of major iridoid glycosides in G. rigescens originated from six different origins, which is helpful for controlling quality of herbal medicines systematically.

    Seven mesocosm-scale constructed wetlands (CWs) of different configurations were operated outdoors for nine months to assess their ability to remove pharmaceuticals and personal care products (PPCPs) from urban wastewaters. CWs differed in some design parameters, namely the presence of plants, the species chosen (i.e., Typha angustifolia vs Phragmites australis), flow configuration (i.e., surface flow vs subsurface flow) and the presence of a gravel bed. A nearby conventional activated-sludge wastewater treatment plant (WWTP) fed with the same sewage was simultaneously monitored for comparison. The PPCPs ketoprofen, naproxen, ibuprofen, diclofenac, salicylic acid, carbamazepine, caffeine, galaxolide, tonalide and methyl dihydrojasmonate were monitored. The presence of plants favoured the removal of some PPCPs. The performance of the mesocosm studied was compound-dependant, soilless CWs showing the highest removal efficiency for ketoprofen, ibuprofen and carbamazepine, while free-water CWs with effluent leaving through the bottom of the tank performed well for the degradation of ketoprofen, salicylic acid, galaxolide and tonalide. Finally, subsurface horizontal flow CWs were efficient for the removal of caffeine. Significant linear correlations were observed between the removal of some PPCPs and temperature or redox potential. Hence, microbiological pathways appear to be the most probable degradation route for PPCPs in the CWs studied. 2010 Elsevier Ltd. All rights reserved.

  5. Comprehensive and comparative ecotoxicological and human risk assessment of polycyclic aromatic hydrocarbons (PAHs) in reef surface sediments and coastal seawaters of Iranian Coral Islands, Persian Gulf.

    The concentration and spatial distribution along with ecotoxicological risk of 30 polycyclic aromatic hydrocarbons were investigated in the reef surface sediments (RSSs) and coastal seawater (CSW) of ten coral Islands from the Persian Gulf, Iran, in January 2015. For all sampling sites, assessment of ecological risk was undertaken using several approaches. Mean concentration of ∑30PAHs varied between 70 and 884ngL -l with an overall mean value of 464ngL -l in the CSW, while the RSS ranged from 274 to 1098ngg -1 dw with a total average of 619ngg -1 dw. The results showed a gradient in PAH concentration and toxicity estimates from the northern Hormoz site increasing to the eastern Kharg site. Most of the toxicity estimates were in the moderate range or less than risk values for damage to the marine environment. The calculated Dermal Hazard Quotient (HQs), the sum of HQs (HI) and other cancer risk values of most compounds were less than safety values at most sites. It means that the possibility of negative effects of PAHs via dermal absorption from sediments for children and adults is low. Some sampling sites studied have already been impacted with hazardous pollutants for an extended period of time and evidence from this investigation demonstrates that mixtures of PAHs may be carcinogenic to humans, especially in the western part of the Gulf.

    2003-01-01

    Full Text Available The imminent prediction on a group of strong earthquakes that occurred in Xinjiang, China in April 1997 is introduced in detail. The prediction was made on the basis of comprehensive analyses on the results obtained by multiple innovative methods including measurements of crustal stress, observation of infrasonic wave in an ultra low frequency range, and recording of abnormal behavior of certain animals. Other successful examples of prediction are also enumerated. The statistics shows that above 40% of 20 total predictions jointly presented by J. Z. Li, Z. Q. Ren and others since 1995 can be regarded as effective. With the above methods, precursors of almost every strong earthquake around the world that occurred in recent years were recorded in our laboratory. However, the physical mechanisms of the observed precursors are yet impossible to explain at this stage.

    The article deals with issues of technical and economic substantiation of priorities and scopes of modernizing the existing thermal power plants (TPPs) in Russia to work out long-term forecasts of the development of the industry. The current situation in the TPP modernization trends is analyzed. The updated initial figures of the capital and operation costs are presented and the obtained estimates of the comparative efficiency of various investment decisions on modernization and equipment replacement at gas-and-oil-burning and coal-fired TPPs with regard to the main zones of the national Unified Power System (UPS) of Russia are cited. The results of optimization of the generating capacity structure underlie a study of alternative TPP modernization strategies that differ in the scope of switching to new technologies, capital intensity, and energy efficiency (decrease in the average heat rate). To provide an integral economic assessment of the above strategies, the authors modified the traditional approach based on determination of the overall discounted costs of power supply (least-cost planning) supplemented with a comparison by the weighted average wholesale price of the electricity. A method for prediction of the wholesale price is proposed reasoning from the direct and dual solutions of the optimization problem. The method can be adapted to various combinations of the mechanisms of payment for the electricity and the capacity on the basis of marginal and average costs. Energy and economic analysis showed that the opposite effects of reduction in the capital investment and fuel saving change in a nonlinear way as the scope of the switch to more advanced power generation technologies at the TPPs increases. As a consequence, a strategy for modernization of the existing power plants rational with respect to total costs of the power supply and wholesale electricity prices has been formulated. The strategy combines decisions on upgrade and replacement of the equipment

    Full Text Available Micraspis discolor (Fabricius (Coleoptera: Coccinellidae is a widely distributed coleoptera predator in southern Asia in rice ecosystem, and adult M. discolor feed on both rice pollen and soft-bodied arthropods. Bitrophic bioassay and tritrophic bioassay were conducted to evaluate the potential impact of Cry1Ac/Cry1Ab-expressing rice Huahui 1 and its non-transgenic counterpart Minghui 63 on fitness parameters of adult M. discolor. The results showed that the survival, and fecundity of this beetle' adults were not different when they fed on Bt rice or non-Bt rice pollen or Nilaparvata lugens (Stål reared on Bt rice or non-Bt rice. Toxicity assessment to ensure M. discolor adults were not sensitive to Cry1Ab or Cry1Ac protein independent from the pollen background, M. discolor adults were fed with an artificial diet containing Cry1Ac, Cry1Ab or both protein approximately 10 times higher concentration than in Huahui 1 rice pollen. No difference was detected for any of the life-table parameters tested between Cry protein-containing and pure diet. Artificial diet containing E-64 (N-(trans-Epoxysuccinyl-L-leucine 4-guanidinobutylamide was included as a positive control. In contrast, the pre-oviposition and fecundity of M. discolor were significantly adversely affected by feeding on E-64-containing diet. In both bioassays, the uptakes of Cry protein by adult M. discolor were tested by ELISA measurements. These results indicated that adults of M. discolor are not affected by Cry1Ab- or Cry1Ac-expressing rice pollen and are not sensitive to Cry protein at concentrations exceeding the levels in rice pollen in Huahui1. This suggests that M. discolor adults would not be harmed by Cry1Ac/Cry1Ab rice if Bt rice Huahui 1 were commercialized.
