    We explored the current practice with respect to the neuropsychological assessment of surgical epilepsy patients in European epilepsy centers, with the aim of harmonizing and establishing common standards. Twenty-six epilepsy centers and members of "E-PILEPSY" (a European pilot network of reference centers in refractory epilepsy and epilepsy surgery), were asked to report the status of neuropsychological assessment in adults and children via two different surveys. There was a consensus among these centers regarding the role of neuropsychology in the presurgical workup. Strong agreement was found on indications (localization, epileptic dysfunctions, adverse drugs effects, and postoperative monitoring) and the domains to be evaluated (memory, attention, executive functions, language, visuospatial skills, intelligence, depression, anxiety, and quality of life). Although 186 different tests are in use throughout these European centers, a core group of tests reflecting a moderate level of agreement could be discerned. Variability exists with regard to indications, protocols, and paradigms for the assessment of hemispheric language dominance. For the tests in use, little published evidence of clinical validity in epilepsy was provided. Participants in the survey reported a need for improvement concerning the validity of the tests, tools for the assessment of everyday functioning and accelerated forgetting, national norms, and test co-normalization. Based on the present survey, we documented a consensus regarding the indications and principles of neuropsychological testing. Despite the variety of tests in use, the survey indicated that there may be a core set of tests chosen based on experience, as well as on published evidence. By combining these findings with the results of an ongoing systematic literature review, we aim for a battery that can be recommended for the use across epilepsy surgical centers in Europe.

  6. Assessing Current State Science Teaching and Learning Standards for Ability to Achieve Climate Science Literacy

    2012-12-01

    Even though there exists a high degree of consensus among scientists about climate change, doubt has actually increased over the last five years within the general U.S. public. In 2006, 79% of those polled agreed that there is evidence for global warming, while only 59% agreed in 2010 (Pew Research Center, 2010). The source for this doubt can be partially attributed to lack of knowledge. Formal education is one mechanism that potentially can address inadequate public understanding as school is the primary place where students - and future citizens - learn about the climate. In a joint effort, several governmental agencies, non-governmental organizations, scientists and educators have created a framework called The Essential Principles of Climate Science Literacy, detailing seven concepts that are deemed vital for individuals and communities to understand Earth's climate system (USGCRP, 2009). Can students reach climate literacy - as defined by these 7 concepts - if they are taught using a curriculum based on the current state standards? To answer this question, the K-12 state science teaching and learning standards for Texas and California - two states that heavily influence nation-wide textbook creation - were compared against the Essential Principles. The data analysis consisted of two stages, looking for: 1) direct reference to "climate" and "climate change" and 2) indirect reference to the 7 Essential Principles through axial coding. The word "climate" appears in the California K-12 science standards 4 times and in the Texas standards 7 times. The word "climate change" appears in the California and Texas standards only 3 times each. Indirect references to the 7 Essential Principles of climate science literacy were more numerous. Broadly, California covered 6 of the principles while Texas covered all 7. In looking at the 7 principles, the second one "Climate is regulated by complex interactions among component of the Earth system" was the most substantively

    2009-01-01

    This study sought to extract information on individual patient habitus from scout imaging and to correlate radiograph tube current settings with enhancement of the coronaries as a function of patient profiles for coronary multidetector computed tomography. Fifty patients underwent coronary 64-slice multidetector computed tomography consisting of 2-plane scouts and electrocardiography-gated coronary studies at 64 x 0.625 mm, radiograph voltage of 120 kVp, and radiograph currents of 295 to 788 mA, which were reconstructed during 65%, 75%, and 85% R-R intervals. Patients' weight was recorded. On scout imaging, chest diameters were determined, and circumferences were calculated. To determine whether body weight showed sex-specific characteristics, t test was used. Pearson correlation determined whether cross-sectional measurements reflected female/male body habitus. On coronary imaging, contrast-to-noise ratios (CNRs) of the aorta and the coronaries were calculated. To assess whether CNRs differed throughout the diastolic phase, t test was used. Data triplets of CNRs and the corresponding current and circumference were plotted; CNRs less than 250 Hounsfield unit (HU) were discarded, dissecting lines as 95th percentiles correlating radiograph currents and patients' circumferences were calculated. Female/male weights differed significantly (P = 0.0006); circumferences based on scouts adequately reflected body weight (coefficients, 0.86 male/0.87 female). Homogenous vascular enhancement of the aorta (mean +/- SD, 344.4 +/- 81.8 HU) and the right (292.3 +/- 82.8 HU) and left (285.8 +/- 81.3 HU) coronaries was achieved (P > 0.005). Ninety-fifth percentile cutoffs identified linear relationships between patient's circumference and the minimal adequate radiograph current achieving CNR less than or equal to 250 HU. Scout imaging can be used to determine individual patient habitus; habitus-adjusted minimal radiograph tube current cutoff levels identified in this study ensuring

    Mitogenome metadata are descriptive terms about the sequence, and its specimen description that allow both to be digitally discoverable and interoperable. Here, we review a sampling of mitogenome metadata published in the journal Mitochondrial DNA between 2005 and 2014. Specifically, we have focused on a subset of metadata fields that are available for GenBank records, and specified by the Genomics Standards Consortium (GSC) and other biodiversity metadata standards; and we assessed their presence across three main categories: collection, biological and taxonomic information. To do this we reviewed 146 mitogenome manuscripts, and their associated GenBank records, and scored them for 13 metadata fields. We also explored the potential for mitogenome misidentification using their sequence diversity, and taxonomic metadata on the Barcode of Life Datasystems (BOLD). For this, we focused on all Lepidoptera and Perciformes mitogenomes included in the review, along with additional mitogenome sequence data mined from Genbank. Overall, we found that none of 146 mitogenome projects provided all the metadata we looked for; and only 17 projects provided at least one category of metadata across the three main categories. Comparisons using mtDNA sequences from BOLD, suggest that some mitogenomes may be misidentified. Lastly, we appreciate the research potential of mitogenomes announced through this journal; and we conclude with a suggestion of 13 metadata fields, available on GenBank, that if provided in a mitogenomes's GenBank record, would increase their research value.

    Definition: Radiofrequency (RF) induces thermal destruction of the targeted tissue by an electrical current at a frequency of 0.5 MHz (RF). As the electrode tip is not heated, there is minimal thermal damage to the surrounding tissues, producing good esthetic results. Therefore, RF ablation is also known as cold ablation or "coblation." Modality: It has three modes of operation: (a) Cut, (b) cut and coagulate and (c) coagulate. Therefore, it can be used for various purposes like incision, ...

  18. Pharmacotherapy of erectile dysfunction: Current standards

    2006-01-01

    Full Text Available Pharmacotherapy is currently the therapeutic option of choice for erectile dysfunction. Comprising mainly intracavernosal injection therapy using alprostadil or alprostadil combined with phentolamine and/or papaverine and oral phosphodiesterase-5 inhibitors, it is safe and effective if appropriately prescribed and administered. The medications in current use produce satisfactory erectile responses by enhancing cavernosal vasodilatation mainly through their ability to promote relaxation of the smooth muscle cells in the corpora cavernosa involving the synthesis and activity of nitric oxide via the cyclic guanosine monophosphate and cyclic adenosine monophosphate biochemical pathways. The main side-effects and complications of intracavernosal injections are postinjection pain, prolonged erections, priapism and penile fibrosis. There may be a variety of side-effects with phosphodiesterase-5 inhibition but these are usually inconsequential. Recent serious ill health and the need for ongoing long-acting nitrate therapy or frequent use of short-acting nitrates for angina are absolute contraindications to the use of phosphodiesterase-5 inhibitors. Caution has to be exercised in prescribing phosphodiesterase-5 inhibitors for patients with impaired renal or hepatic functions or receiving multi-drug therapy for any systemic disease. All patients presenting with erectile dysfunction should be investigated and treated for cardiovascular risk factors. They should also be counseled regarding lifestyle factors particularly healthy balanced diet, regular physical exercise and inappropriate social habits.

    Full Text Available Definition: Radiofrequency (RF induces thermal destruction of the targeted tissue by an electrical current at a frequency of 0.5 MHz (RF. As the electrode tip is not heated, there is minimal thermal damage to the surrounding tissues, producing good esthetic results. Therefore, RF ablation is also known as cold ablation or "coblation." Modality: It has three modes of operation: (a Cut, (b cut and coagulate and (c coagulate. Therefore, it can be used for various purposes like incision, ablation, fulguration, shave excision and coagulation. Because of the coagulation facility, hemostasis can be achieved and operation becomes easier and faster. Indications: It is effective in treating various skin conditions like dermatosis papulosa nigra, warts, molluscum contagiosum, colloid milia, acquired junctional, compound and dermal melanocytic nevi, seborrheic keratosis, skin tags, granuloma pyogenicum, verrucous epidermal nevi, xanthelesma, rhinophyma, superficial basal cell carcinoma and telangiectasia. It can also be used for cosmetic indications such as resurfacing, earlobe repair and blepharoplasty. Anesthesia: The procedure is accomplished either under topical anesthesia eutactic mixture of local anesthetics or local injectable anesthesia, under all aseptic precautions. Procedure: While operating, only the tip of the electrode should come in contact with the tissue. Actual contact of the electrode with the tissue should be very brief in order to prevent excessive damage to the deeper tissues. This can be accomplished by moving the electrode quickly. Complications: Complications are uncommon and mainly occur due to an improper technique. The treating physician should be aware of the contraindications of the procedure as listed in these guidelines. Physician qualification: RF surgery may be performed by a dermatologist who has acquired adequate training during post-graduation or through recognized fellowships and workshops dedicated to RF surgery.

    Full Text Available Science standards have a long history in the United States and currently form the backbone of efforts to improve primary and secondary education in science, technology, engineering, and math (STEM. Although there has been much political controversy over the influence of standards on teacher autonomy and student performance, little light has been shed on how well standards cover science content. We assessed the coverage of genetics content in the Next Generation Science Standards (NGSS using a consensus list of American Society of Human Genetics (ASHG core concepts. We also compared the NGSS against state science standards. Our goals were to assess the potential of the new standards to support genetic literacy and to determine if they improve the coverage of genetics concepts relative to state standards. We found that expert reviewers cannot identify ASHG core concepts within the new standards with high reliability, suggesting that the scope of content addressed by the standards may be inconsistently interpreted. Given results that indicate that the disciplinary core ideas (DCIs included in the NGSS documents produced by Achieve, Inc. clarify the content covered by the standards statements themselves, we recommend that the NGSS standards statements always be viewed alongside their supporting disciplinary core ideas. In addition, gaps exist in the coverage of essential genetics concepts, most worryingly concepts dealing with patterns of inheritance, both Mendelian and complex. Finally, state standards vary widely in their coverage of genetics concepts when compared with the NGSS. On average, however, the NGSS support genetic literacy better than extant state standards.

    We compute the complete one-loop contributions to low-energy charged current weak interaction observables in the minimal supersymmetric standard model (MSSM). We obtain the constraints on the MSSM parameter space which arise when precision low-energy charged current data are analyzed in tandem with measurements of the muon anomaly. While the data allow the presence of at least one light neutralino, they also imply a pattern of mass splittings among first and second generation sleptons and squarks which contradicts predictions of widely used models for supersymmetry-breaking mediation.

    Full Text Available Cloud Computing technologies and cloud-based Geographic Information Systems have became widely used in recent decades. However, the complexity and size of geospatial datasets remains growing and sometimes become going out of the cloud infrastructure paradigm. Additionally, many of currently used client devices have sufficient computational resources to store and process some amounts of data directly. Consequently, multilevel management techniques are demanded that support capabilities of horizontal (client-to-client data flows in addition to vertical (cloud-to-client data flows. These tendencies in information technologies (in general have led to the appearance of Fog Computing paradigm that extends a cloud infrastructure with the computational resources of client devices and implements client-side data storage, management and interchange. This position paper summarizes and discusses mentioned tendencies in connection with a number of available Open Geospatial Consortium standards. The paper highlights the standards, which can be recognized as the platform for the Fog Computing implementation into geospatial domain, and analyzing their strong and weak features from the Fog Computing point of view. The analysis is built upon author’s experience in implementation of the client-side geospatial Web services.

    1994-04-01

    777 cerebral MRI examinations of children aged 3 days to 14 years were staged for myelination to establish an age standardization. Staging was performed using a system proposed in a previous paper, separately ranking 10 different regions of the brain. Interpretation of the results led to the identification of foue clinical diagnoses that are frequently associated with delays in myelination: West syndrome, cerebral palsy, developmental retardation, and congenital anomalies. In addition, it was found that assessment of myelination in children with head injuries was not practical as alterations in MRI signal can simulate earlier stages of myelination. Age limits were therefore calculated from the case material after excluding all children with these conditions. When simplifications of the definition of the stages are applied, these age limits for the various stages of myelination of each of the 10 regions of the brain make the staging system applicable for routine assessment of myelination.

    In this study, we investigated current personality assessment practice and attitudes toward Rorschach (Exner, 2003) usage by 215 psychologists. We administered an Internet survey to members of the Society for Personality Assessment (SPA) and the American Psychological Association. Results were similar to those of past surveys, but the importance of using tests with strong psychometric properties was greater in this study. The majority of respondents reported using the Rorschach and supporting efforts to standardize and psychometrically validate the test. However, SPA members agreed more strongly than non-SPA members that the Rorschach is an effective test. Implications and directions for future research are discussed.

  10. Infection control: its evolution to the current standard precautions.

    2003-05-01

    The use of appropriate infection control precautions to protect against transmission of bloodborne and other occupational microbial pathogens has become a routine component of health care provision. Evolution and revision of recommendations continues to be based on updated scientific information, as well as documented and inferred clinical applications of new knowledge. In addition, surveillance of occupational risks in medical treatment settings often has served as a basis for subsequent disease prevention recommendations for dental care. Guidelines designed to protect dental professionals and their patients have focused on bloodborne pathogens since the first published American Dental Association recommendations in the 1970s. Subsequent statements developed by the Centers for Disease Control and Prevention, the ADA and other organizations during the past 30 years also have addressed prevention of other infections, transmitted by either direct or indirect contact with a variety of potentially infectious body fluids. Review of the major features of these recommendations provides an appropriate framework to consider current guideline revisions. The success of long-standing universal precautions, or UP, against bloodborne infection has been augmented with the incorporation of body substance isolation, or BSI, practices into the infection control protocol designated "standard precautions." Combination of the major tenets of UP with the BSI systems routinely employed in acute care facilities affords all health care professionals the means of preventing a spectrum of bloodborne, respiratory, contact and other potential exposures during provision of patient care. As infection control recommendations for dentistry are updated this year, they undoubtedly will include guidelines expanding previous UP to provide expanded protection for dental professionals in the multiple types of nonacute treatment settings in which routine treatment is provided.

  12. Fibrinolysis standards: a review of the current status.

    Science.gov (United States)

    Thelwell, C

    2010-07-01

    Biological standards are used to calibrate measurements of components of the fibrinolytic system, either for assigning potency values to therapeutic products, or to determine levels in human plasma as an indicator of thrombotic risk. Traditionally WHO International Standards are calibrated in International Units based on consensus values from collaborative studies. The International Unit is defined by the response activity of a given amount of the standard in a bioassay, independent of the method used. Assay validity is based on the assumption that both standard and test preparation contain the same analyte, and the response in an assay is a true function of this analyte. This principle is reflected in the diversity of source materials used to prepare fibrinolysis standards, which has depended on the contemporary preparations they were employed to measure. With advancing recombinant technology, and improved analytical techniques, a reference system based on reference materials and associated reference methods has been recommended for future fibrinolysis standards. Careful consideration and scientific judgement must however be applied when deciding on an approach to develop a new standard, with decisions based on the suitability of a standard to serve its purpose, and not just to satisfy a metrological ideal. 2010 The International Association for Biologicals.

  13. Standard practice for characterization of coatings using conformable Eddy-Current sensors without coating reference standards

    CERN Document Server

    American Society for Testing and Materials. Philadelphia

    2011-01-01

    1.1 This practice covers the use of conformable eddy-current sensors for nondestructive characterization of coatings without standardization on coated reference parts. It includes the following: (1) thickness measurement of a conductive coating on a conductive substrate, (2) detection and characterization of local regions of increased porosity of a conductive coating, and (3) measurement of thickness for nonconductive coatings on a conductive substrate or on a conductive coating. This practice includes only nonmagnetic coatings on either magnetic (μ ≠ μ0) or nonmagnetic (μ = μ0) substrates. This practice can also be used to measure the effective thickness of a process-affected zone (for example, shot peened layer for aluminum alloys, alpha case for titanium alloys). For specific types of coated parts, the user may need a more specific procedure tailored to a specific application.

  14. Reef Fish Survey Techniques: Assessing the Potential for Standardizing Methodologies.

    Directory of Open Access Journals (Sweden)

    Zachary R Caldwell

    Full Text Available Dramatic changes in populations of fishes living on coral reefs have been documented globally and, in response, the research community has initiated efforts to assess and monitor reef fish assemblages. A variety of visual census techniques are employed, however results are often incomparable due to differential methodological performance. Although comparability of data may promote improved assessment of fish populations, and thus management of often critically important nearshore fisheries, to date no standardized and agreed-upon survey method has emerged. This study describes the use of methods across the research community and identifies potential drivers of method selection. An online survey was distributed to researchers from academic, governmental, and non-governmental organizations internationally. Although many methods were identified, 89% of survey-based projects employed one of three methods-belt transect, stationary point count, and some variation of the timed swim method. The selection of survey method was independent of the research design (i.e., assessment goal and region of study, but was related to the researcher's home institution. While some researchers expressed willingness to modify their current survey protocols to more standardized protocols (76%, their willingness decreased when methodologies were tied to long-term datasets spanning five or more years. Willingness to modify current methodologies was also less common among academic researchers than resource managers. By understanding both the current application of methods and the reported motivations for method selection, we hope to focus discussions towards increasing the comparability of quantitative reef fish survey data.

  15. Community Assessment: A Current Essential Need

    Directory of Open Access Journals (Sweden)

    Full Text Available Health; as a basic right of the people and essential demand; should be considered as a joint responsibility of the government and people of a community. As much as the people of a community aware and involved in the individual health promotion and problem solving of their community in all dimensions, the probability of reaching to favorable health measurements is also increased. Community assessment is considered as a foundation for health improving and promoting the community members. The main objectives of community assessment are; to identify factors that affect the health of a population and determine the availability of resources within the community to adequately address these factors. In this Vera, community leaders, public health agencies, businesses, hospitals, private practitioners, and academic centers have each one a defined role. These groups can begin to answer key questions such as (a “What are the strengths in our community?” (b “What health concerns do community members have?” and (c “What resources are available and what do we need in the community to address these concerns? An important use of a community health assessment is to create Community Health Action to develop effective community health strategies. The health reform plan of Islamic Republic of Iran, started at the earlier months of the current year (2014, with establishing of the family physician program begun firstly at the level of rural regions, then will developed to cities with population 20000 to 500000 also borderlines of metropolitans cities and finally in the future, covering all urban eras of cities in the country aimed to executive the referral system with all its attributes. Being a full time physician along with a comprehensive teamwork including different prestigious health workers prepare a gold opportunity for implementation of community assessment in these regions. Although, some efforts have been accomplished in some parts of country by

  16. Technical standardization of oil well abandonment: a review of current standards and technologies

    2008-07-01

    The objective of this study is to provide a new methodology for well abandonment. This practice is becoming more and more important because of the increasing number of production fields being abandoned. We strongly recommend a study of cement slurries properties for specific use in temporary and permanent abandonment plugs based on the estimation of the cement slurry hardened when placed in the well. By using specific additives, it is possible to achieve very stable slurries. For example, when permeability is reduced, formation fluid migration can be blocked and chemical reactions between the fluid and the slurry may be inhibited. With this objective, we present a laboratory investigation model and an example of slurry testing recommendation. During the abandonment operation, all records of the well characteristics should be maintained to include the reason for the abandonment, and location of fresh water, brine, and hydrocarbon zones that may exist. This documentation will also allow the analysis of solutions for the problems that originally caused the abandonment of the well. This data could be important for future use by environmental protection commissions to reopen or to drill an adjacent well. Given the high price of oil, it may now be economically feasible to reopen the well, if the reason for abandonment was low productivity. This way, a critical analysis of the current conditions of well and field abandonment in the country is presented. Based on this information, a review of the current standards is suggested. (author)

  17. Is it time to reassess current safety standards for glyphosate-based herbicides?

    2017-06-01

    Use of glyphosate-based herbicides (GBHs) increased ∼100-fold from 1974 to 2014. Additional increases are expected due to widespread emergence of glyphosate-resistant weeds, increased application of GBHs, and preharvest uses of GBHs as desiccants. Current safety assessments rely heavily on studies conducted over 30 years ago. We have considered information on GBH use, exposures, mechanisms of action, toxicity and epidemiology. Human exposures to glyphosate are rising, and a number of in vitro and in vivo studies challenge the basis for the current safety assessment of glyphosate and GBHs. We conclude that current safety standards for GBHs are outdated and may fail to protect public health or the environment. To improve safety standards, the following are urgently needed: (1) human biomonitoring for glyphosate and its metabolites; (2) prioritisation of glyphosate and GBHs for hazard assessments, including toxicological studies that use state-of-the-art approaches; (3) epidemiological studies, especially of occupationally exposed agricultural workers, pregnant women and their children and (4) evaluations of GBHs in commercially used formulations, recognising that herbicide mixtures likely have effects that are not predicted by studying glyphosate alone.

    2016-07-18

    Disparate data must be represented in a common format to enable comparison across multiple institutions and facilitate big data science. Nursing assessments represent a rich source of information. However, a lack of agreement regarding essential concepts and standardized terminology prevent their use for big data science in the current state. The purpose of this study was to align a minimum set of physiological nursing assessment data elements with national standardized coding systems. Six institutions shared their 100 most common electronic health record nursing assessment data elements. From these, a set of distinct elements was mapped to nationally recognized Logical Observations Identifiers Names and Codes (LOINC®) and Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT®) standards. We identified 137 observation names (55% new to LOINC), and 348 observation values (20% new to SNOMED CT) organized into 16 panels (72% new LOINC). This reference set can support the exchange of nursing information, facilitate multi-site research, and provide a framework for nursing data analysis. © The Author(s) 2016.

    2007-10-01

    Full Text Available Indexing is one of the most important methods of content representation where by assigning descriptors to the documents, their subject content are made known. Since index and indexing are remarkably significant in information retrieval, its quality and evaluation and provision of criteria and standards had always been the mainstay of researchers in this field. Given the fact that Indexing is a complex process, offering definitions, principles and methods could be step towards optimal use of the information. The present study, while offering a capsule definition of index, will investigate the indexing evaluation criteria and would follow it up with a definition of indexing. Finally a number of standards in the field of indexing are presented and would make its conclusions.

    2017-03-01

    Thermal modalities represent the only currently viable mass fever screening approach for outbreaks of infectious disease pandemics such as Ebola and SARS. Non-contact infrared thermometers (NCITs) and infrared thermographs (IRTs) have been previously used for mass fever screening in transportation hubs such as airports to reduce the spread of disease. While NCITs remain a more popular choice for fever screening in the field and at fixed locations, there has been increasing evidence in the literature that IRTs can provide greater accuracy in estimating core body temperature if appropriate measurement practices are applied - including the use of technically suitable thermographs. Therefore, the purpose of this study was to develop a battery of evaluation test methods for standardized, objective and quantitative assessment of thermograph performance characteristics critical to assessing suitability for clinical use. These factors include stability, drift, uniformity, minimum resolvable temperature difference, and accuracy. Two commercial IRT models were characterized. An external temperature reference source with high temperature accuracy was utilized as part of the screening thermograph. Results showed that both IRTs are relatively accurate and stable (<1% error of reading with stability of +/-0.05°C). Overall, results of this study may facilitate development of standardized consensus test methods to enable consistent and accurate use of IRTs for fever screening.

  19. PASSING STANDARDIZED ASSESSMENTS WITH FADING PROMPTS

    Directory of Open Access Journals (Sweden)

    Amy Marie GREENE

    2015-11-01

    Full Text Available Introduction: No Child Left Behind Act of 2001 mandates that all students perform at a level of proficient on state assessments. This includes students with learning and intellectual disabilities who are inherently performing below grade level. Given that schools are held accountable for meeting these goals and some states are not allowing students to graduate if they do not pass the assessments, this is a large concern for students, parents, teachers, and administration Method: Forty-five students with a disability in writing or an intellectual disability participated in this quasi-experimental, single-group, pretest-posttest design that evaluated the effectiveness of the Fading Prompts through Graphic Organizers method for students with learning and intellectual disabilities in written expression as measured according to the Pennsylvania System of School Assessment. Results: Data analyses were conducted through the use of four dichotomies for percent differences, which compared teacher administered pretests and posttests, pretests and the state administered PSSA, teacher administered posttests and the PSSA, and the participants’ PSSA and the average state PSSA score. All forty-five students performed at a below basic level during baseline and a proficient level on the posttest. The learned skills generalized to the PSSA with forty-three students earning a passing score of proficient, while two students advanced to basic. Conclusion: Based on the outcomes of this study, it is highly recommended that this program be utilized at least for students with learning and intellectual disabilities until further research can be done.

    2011-10-31

    Current interest expressed by industry in HTGR plants, particularly modular plants with power up to about 600 MW(e) per unit, has prompted NRC to task PNNL with assessing the currently available literature related to codes and standards applicable to HTGR plants, the operating history of past and present HTGR plants, and with evaluating the proposed designs of RPV and associated piping for future plants. Considering these topics in the order they are arranged in the text, first the operational histories of five shut-down and two currently operating HTGR plants are reviewed, leading the authors to conclude that while small, simple prototype HTGR plants operated reliably, some of the larger plants, particularly Fort St. Vrain, had poor availability. Safety and radiological performance of these plants has been considerably better than LWR plants. Petroleum processing plants provide some applicable experience with materials similar to those proposed for HTGR piping and vessels. At least one currently operating plant - HTR-10 - has performed and documented a leak before break analysis that appears to be applicable to proposed future US HTGR designs. Current codes and standards cover some HTGR materials, but not all materials are covered to the high temperatures envisioned for HTGR use. Codes and standards, particularly ASME Codes, are under development for proposed future US HTGR designs. A 'roadmap' document has been prepared for ASME Code development; a new subsection to section III of the ASME Code, ASME BPVC III-5, is scheduled to be published in October 2011. The question of terminology for the cross-duct structure between the RPV and power conversion vessel is discussed, considering the differences in regulatory requirements that apply depending on whether this structure is designated as a 'vessel' or as a 'pipe'. We conclude that designing this component as a 'pipe' is the more appropriate choice, but that the ASME BPVC

    2016-01-01

    The current study evaluated why and how school mental health clinicians use standardized assessment tools in their work with youth and families. Quantitative and qualitative (focus group) data were collected prior to and following a training and consultation sequence as part of a trial program to assess school clinician's (n = 15) experiences administering standardized tools to youth on their caseloads (n = 191). Findings indicated that, although assessment use was initially somewhat low, clinicians used measures to conduct initial assessments with the bulk of their caseloads (average = 62.2%) during the implementation period. Clinicians also reported on factors influencing their use of assessments at the client, provider, and system levels; perceived functions of assessment; student responses to assessment use; and use of additional sources of clinically-relevant information (primarily educational data) for the purposes of assessment and progress monitoring. Implications for the contextual appropriateness of standardized assessment and training in assessment tools are discussed.

  3. Performance Standards': Utility for Different Uses of Assessments

    Directory of Open Access Journals (Sweden)

    Robert L. Linn

    2003-09-01

    Full Text Available Performance standards are arguably one of the most controversial topics in educational measurement. There are uses of assessments such as licensure and certification where performance standards are essential. There are many other uses, however, where performance standards have been mandated or become the preferred method of reporting assessment results where the standards are not essential to the use. Distinctions between essential and nonessential uses of performance standards are discussed. It is argued that the insistence on reporting in terms of performance standards in situations where they are not essential has been more harmful than helpful. Variability in the definitions of proficient academic achievement by states for purposes of the No Child Left Behind Act of 2001 is discussed and it is argued that the variability is so great that characterizing achievement is meaningless. Illustrations of the great uncertainty in standards are provided.

    The trophic status assessment of lakes in different lake regions may provide important and fundamental information for lake trophic state classification and eutrophication control. In this study, a region-specific lake eutrophication assessment standard was established through a frequency distribution method based on chlorophyll-a concentration. The assessment standards under the oligotrophic state for lakes in the Eastern plain, Yungui Plateau, Northeast Plain and Mountain Mongolia-Xinjiang regions are total phosphorus of 0.068, 0.005, 0.011, 0.005 mg/L; total nitrogen of 1.00, 0.16, 0.37, 0.60 mg/L; Secchi depth of 0.60, 8.00, 1.55, 3.00 m; and COD(Mn) of 2.24, 1.00, 5.11, 4.00 mg/L, respectively. Moreover, a region-specific comprehensive trophic level index was developed to provide an understandable assessment method for the public. The results indicated that the frequency distribution analysis based on chlorophyll-a combined with trophic level index provided a useful metric for the assessment of the lake trophic status. In addition, the difference of eutrophication assessment standards in different lake regions was analyzed, which suggested that the sensitivities of algae to nutrients and the assessment standard of trophic status possessed significant regional differences for the four lake ecoregions. Lake eutrophication assessment standards would contribute to maximizing the effectiveness of future management strategies, to control and minimize lake eutrophication problems.

    Ochal-Choińska, Aleksandra

    2016-01-01

    The paper is an update of 2011 Standards for Ultrasound Assessment of Salivary Glands, which were developed by the Polish Ultrasound Society. We have described current ultrasound technical requirements, assessment and measurement techniques as well as guidelines for ultrasound description. We have also discussed an ultrasound image of normal salivary glands as well as the most important pathologies, such as inflammation, sialosis, collagenosis, injuries and proliferative processes, with particular emphasis on lesions indicating high risk of malignancy. In acute bacterial inflammation, the salivary glands appear as hypoechoic, enlarged or normal-sized, with increased parenchymal flow. The echogenicity is significantly increased in viral infections. Degenerative lesions may be seen in chronic inflammations. Hyperechoic deposits with acoustic shadowing can be visualized in lithiasis. Parenchymal fibrosis is a dominant feature of sialosis. Sjögren syndrome produces different pictures of salivary gland parenchymal lesions at different stages of the disease. Pleomorphic adenomas are usually hypoechoic, well-defined and polycyclic in most cases. Warthin tumor usually presents as a hypoechoic, oval-shaped lesion with anechoic cystic spaces. Malignancies are characterized by blurred outlines, irregular shape, usually heterogeneous echogenicity and pathological neovascularization. The accompanying metastatic lesions are another indicator of malignancy, however, final diagnosis should be based on biopsy findings. PMID:27446602

    Standards have a significant role in showing the minimum level of optimal optimum and the expected performance. Since the perfusion technology staffs play an the leading role in providing the quality services to the patients undergoing open heart surgery with cardiopulmonary bypass machine, this study aimed to assess the standards on how Iranian perfusion technology staffs evaluate and manage the patients during the cardiopulmonary bypass process and compare their practice with the recommended standards by American Society of Extracorporeal Technology. In this descriptive study, data was collected from 48 Iranian public hospitals and educational health centers through a researcher-created questionnaire. The data collection questionnaire assessed the standards which are recommended by American Society of Extracorporeal Technology. Findings showed that appropriate measurements were carried out by the perfusion technology staffs to prevent the hemodilution and avoid the blood transfusion and unnecessary blood products, determine the initial dose of heparin based on one of the proposed methods, monitor the anticoagulants based on ACT measurement, and determine the additional doses of heparin during the cardiopulmonary bypass based on ACT or protamine titration. It was done only in 4.2% of hospitals and health centers. Current practices of cardiopulmonary perfusion technology in Iran are inappropriate based on the standards of American Society of Cardiovascular Perfusion. This represents the necessity of authorities' attention to the validation programs and development of the caring standards on one hand and continuous assessment of using these standards on the other hand.

  16. Air Emissions Damages from Municipal Drinking Water Treatment Under Current and Proposed Regulatory Standards.

    Gingerich, Daniel B; Mauter, Meagan S

    2017-09-19

    Water treatment processes present intersectoral and cross-media risk trade-offs that are not presently considered in Safe Drinking Water Act regulatory analyses. This paper develops a method for assessing the air emission implications of common municipal water treatment processes used to comply with recently promulgated and proposed regulatory standards, including concentration limits for, lead and copper, disinfection byproducts, chromium(VI), strontium, and PFOA/PFOS. Life-cycle models of electricity and chemical consumption for individual drinking water unit processes are used to estimate embedded NO x , SO 2 , PM 2.5 , and CO 2 emissions on a cubic meter basis. We estimate air emission damages from currently installed treatment processes at U.S. drinking water facilities to be on the order of $500 million USD annually. Fully complying with six promulgated and proposed rules would increase baseline air emission damages by approximately 50%, with three-quarters of these damages originating from chemical manufacturing. Despite the magnitude of these air emission damages, the net benefit of currently implemented rules remains positive. For some proposed rules, however, the promise of net benefits remains contingent on technology choice.

  2. Environmental assessment. Energy efficiency standards for consumer products

    Energy Technology Data Exchange (ETDEWEB)

    McSwain, Berah

    1980-06-01

    The Energy Policy and Conservation Act of 1975 requires DOE to prescribe energy efficiency standards for 13 consumer products. The Consumer Products Efficiency Standards (CPES) program covers: refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners (cooling and heat pumps), furnaces, dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers. This Environmental Assessment evaluates the potential environmental and socioeconomic impacts expected as a result of setting efficiency standards for all of the consumer products covered by the CPES program. DOE has proposed standards for eight of the products covered by the Program in a Notice of Proposed Rulemaking (NOPR). DOE expects to propose standards for home heating equipment, central air conditioners (heat pumps only), dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers in 1981. No significant adverse environmental or socioeconomic impacts have been found to result from instituting the CPES.

    2009-01-01

    As one of its many responses to the 2003 Space Shuttle Columbia accident, NASA decided to develop a formal standard for models and simulations (M&S). Work commenced in May 2005. An interim version was issued in late 2006. This interim version underwent considerable revision following an extensive Agency-wide review in 2007 along with some additional revisions as a result of the review by the NASA Engineering Management Board (EMB) in the first half of 2008. Issuance of the revised, permanent version, hereafter referred to as the M&S Standard or just the Standard, occurred in July 2008. Bertch, Zang and Steeleiv provided a summary review of the development process of this standard up through the start of the review by the EMB. A thorough recount of the entire development process, major issues, key decisions, and all review processes are available in Ref. v. This is the second of a pair of papers providing a summary of the final version of the Standard. Its focus is the Credibility Assessment Scale, a key feature of the Standard, including an example of its application to a real-world M&S problem for the James Webb Space Telescope. The companion paper summarizes the overall philosophy of the Standard and an overview of the requirements. Verbatim quotes from the Standard are integrated into the text of this paper, and are indicated by quotation marks.

  4. Standards of Ombudsman Assessment: A New Normative Concept?

    Directory of Open Access Journals (Sweden)

    Milan Remac

    2013-07-01

    Full Text Available Today, an ombudsman is a traditional component of democratic legal systems. Generally, reports of the ombudsman are not legally binding. Due to this fact, the ombudsman can rely only on his own persuasiveness, on his acceptance by individuals and state institutions, on the understanding of the administration and on the accessibility and transparency of rules that underpin his reports. During investigations, ombudsmen assess whether the administration has acted in accordance with certain legal or extra-legal standards. Depending on the legal system, ombudsmen can investigate whether there is an instance of maladministration in the activities of administrative bodies, whether the administration has acted ‘properly’, whether it has acted in accordance with the law, whether administrative actions have breached the human rights of complainants or whether the actions of the administration were in accordance with anti-corruption rules etc. Regardless of the legislative standard of an ombudsman’s control, the ombudsman should consider and assess the situation described in complaints against certain criteria or against certain normative standards. A distinct set of standards which ombudsmen use during their investigation, or at least a clear statement of their assessment criteria, can increase the transparency of their procedures and the persuasiveness of their reports. Are the normative standards used by different ombudsmen the same? Do they possibly create a new normative concept? And can it possibly lead to a higher acceptance of their reports by the administration?

    In the past decade, many guidance documents have been issued through collaboration of global organizations and regulatory authorities. Most of these are applicable to new products, but there is a risk that currently marketed products will not meet the new compliance standards during audits and inspections while companies continue to make changes through the product life cycle for continuous improvement or market demands. This discussion presents different strategies to bringing drug product marketing applications to meet current and emerging standards. It also discusses stability and method designs to meet process validation and global development efforts.

  6. Standardizing Quality Assessment of Fused Remotely Sensed Images

    Science.gov (United States)

    Pohl, C.; Moellmann, J.; Fries, K.

    2017-09-01

    The multitude of available operational remote sensing satellites led to the development of many image fusion techniques to provide high spatial, spectral and temporal resolution images. The comparison of different techniques is necessary to obtain an optimized image for the different applications of remote sensing. There are two approaches in assessing image quality: 1. Quantitatively by visual interpretation and 2. Quantitatively using image quality indices. However an objective comparison is difficult due to the fact that a visual assessment is always subject and a quantitative assessment is done by different criteria. Depending on the criteria and indices the result varies. Therefore it is necessary to standardize both processes (qualitative and quantitative assessment) in order to allow an objective image fusion quality evaluation. Various studies have been conducted at the University of Osnabrueck (UOS) to establish a standardized process to objectively compare fused image quality. First established image fusion quality assessment protocols, i.e. Quality with No Reference (QNR) and Khan's protocol, were compared on varies fusion experiments. Second the process of visual quality assessment was structured and standardized with the aim to provide an evaluation protocol. This manuscript reports on the results of the comparison and provides recommendations for future research.

    The benefit of small animal imaging is directly linked to the validity and reliability of the collected data. If the data (regardless of the modality used) are not reproducible and/or reliable, then the outcome of the data is rather questionable. Therefore, standardization of the use of small animal imaging equipment, as well as of animal handling in general, is of paramount importance. In a recent paper, guidance for efficient small animal imaging quality control was offered and discussed, among others, the use of phantoms in setting up a quality control program (Osborne et al. 2016). The same phantoms can be used to standardize image quality parameters for multi-center studies or multi-scanners within center studies. In animal experiments, the additional complexity due to animal handling needs to be addressed to ensure standardized imaging procedures. In this review, we will address the current status of standardization in preclinical imaging, as well as potential benefits from increased levels of standardization.

    Many countries try to efficiently deliver high quality healthcare services at lower and manageable costs where healthcare information and communication technologies (ICT) standardisation may play an important role. New Zealand provides a good model of healthcare ICT standardisation. The purpose of this study was to review the current healthcare ICT standardisation and progress in New Zealand. This study reviewed the reports regarding the healthcare ICT standardisation in New Zealand. We also investigated relevant websites related with the healthcare ICT standards, most of which were run by the government. Then, we summarised the governance structure, standardisation processes, and their output regarding the current healthcare ICT standards status of New Zealand. New Zealand government bodies have established a set of healthcare ICT standards and clear guidelines and procedures for healthcare ICT standardisation. Government has actively participated in various enactments of healthcare ICT standards from the inception of ideas to their eventual retirement. Great achievements in eHealth have already been realized, and various standards are currently utilised at all levels of healthcare regionally and nationally. Standard clinical terminologies, such as International Classification of Diseases (ICD) and Systematized Nomenclature of Medicine - Clinical Terms (SNOMED-CT) have been adopted and Health Level Seven (HL7) standards are actively used in health information exchanges. The government to New Zealand has well organised ICT institutions, guidelines, and regulations, as well as various programs, such as e-Medications and integrated care services. Local district health boards directly running hospitals have effectively adopted various new ICT standards. They might already be benefiting from improved efficiency resulting from healthcare ICT standardisation.

    2013-10-01

    Vascular cognitive impairment (VCI) includes vascular dementia (VaD), vascular mild cognitive impairment (VaMCI) and mixed dementia. In clinical practice, VCI concerns patients referred for clinical stroke or cognitive complaint. To improve the characterization of VCI and to refine its diagnostic criteria, an international group has elaborated a new standardized evaluation battery of clinical, cognitive, behavioral and neuroradiological data which now constitutes the reference battery. The adaption of the battery for French-speaking subjects is reported as well as preliminary results of the on-going validation study of the GRECOG-VASC group [Clinical Trial NCT01339195]. The diagnostic accuracy of various screening tests is reviewed and showed an overall sub-optimal sensitivity (dementia. In addition to the well known NINDS-AIREN criteria of VaD, criteria of VCI have been recently proposed which are based on the demonstration of a cognitive disorder by neuropsychological testing and either history of clinical stroke or presence of vascular lesion by neuroimaging suggestive of a link between cognitive impairment and vascular disease. A memory deficit is no longer required for the diagnosis of VaD as it is based on the cognitive decline concerning two or more domains that affect activities of daily living. Both VaMCI and VaD are classified as probable or possible. These new criteria have yet to be validated. Considerable uncertainties remain regarding the determinant of VCI, and especially the lesion amount inducing VCI and VaD. The interaction between lesion amount and its location is currently re-examined using recent techniques for the analysis of MRI data. The high frequency of associated Alzheimer pathology is now assessable in vivo using amyloid imaging. The first studies showed that about a third of patients with VaD due to small vessel disease or with poststroke dementia have amyloid PET imaging suggestive of AD. These new techniques will examine the

  3. Training in clinical forensic medicine in the UK--perceptions of current regulatory standards.

    Science.gov (United States)

    Stark, Margaret M; Norfolk, Guy A

    2011-08-01

    As clinical forensic medicine (CFM) is not currently recognised as a speciality in the UK there are no nationally agreed mandatory standards for training forensic physicians in either general forensic (GFM) or sexual offence medicine (SOM). The General Medical Council (GMC), the medical regulator in the UK, has issued clear standards for training in all specialities recommending that "trainees must be supported to acquire the necessary skills and experience through induction, effective educational supervision, an appropriate workload and time to learn". In order to evaluate the current situation in the field of clinical forensic medicine, doctors who have recently (within the last two years) started working in the field "trainees" (n = 38), and trainers (n = 61) with responsibility for clinical and educational supervision of new trainees, were surveyed by questionnaire to gather their perceptions of how the relevant GMC standards are being met in initial on-the-job training. Telephone interviews were performed with eleven doctors working as clinical or medical directors to determine their views. It is clear that currently the quality of training in CFM is sub-standard and inconsistent and that the published standards, as to the minimum requirement for training that must be met by post-graduate medical and training providers at all levels, are not being met. The Faculty of Forensic and Legal Medicine (FFLM) needs to set explicit minimum standards which will comply with the regulator and work to pilot credentialing for forensic physicians. A number of recommendations are made for urgent FFLM development. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

    The Nuclear Medicine Global Initiative (NMGI) was formed in 2012 and consists of 13 international organizations with direct involvement in nuclear medicine. The underlying objectives of the NMGI are to promote human health by advancing the field of nuclear medicine and molecular imaging, encourage global collaboration in education, and harmonize procedure guidelines and other policies that ultimately lead to improvements in quality and safety in the field throughout the world. For its first project, the NMGI decided to consider the issues involved in the standardization of administered activities in pediatric nuclear medicine. It was decided to divide the final report of this project into 2 parts. Part 1 was published in this journal in the spring of 2015. This article presents part 2 of the final report. It discusses current standards for administered activities in children and adolescents that have been developed by various professional organizations. It also presents an evaluation of the current practice of pediatric nuclear medicine specifically with regard to administered activities as determined by an international survey of 313 nuclear medicine clinics and centers from 29 countries. Lastly, it provides recommendations for a path toward global standardization of the administration of radiopharmaceuticals in children. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    The standard model of particle physics is our best description yet of fundamental particles and their interactions, but it is known to be incomplete. As yet undiscovered particles and interactions might exist. One of the most powerful ways to search for new particles is by studying processes known as flavour-changing neutral current decays, whereby a quark changes its flavour without altering its electric charge. One example of such a transition is the decay of a beauty quark into a strange quark. Here we review some intriguing anomalies in these decays, which have revealed potential cracks in the standard model—hinting at the existence of new phenomena.

    Direct assessment of health professional student performance of clinical skills can be accurately performed in the standardized performance assessment laboratory (SPAL), typically by health professional faculty. However, owing to time and economic considerations, nonmedical individuals have been specially trained to perform the same function (standardized patients [SPs]). This study compared the assessment scores of the history and physical examination components of a SPAL designed for second-year podiatric medical students at Des Moines University (DMU) by a podiatry medical faculty member and SPs. A total of 101 students from the classes of 2015 and 2016 were evaluated in 2013 and 2014 by 11 to 13 SPs from the DMU SPAL program. The video recordings of these 101 students were then evaluated by one faculty member from the College of Podiatric Medicine and Surgery at DMU. The Pearson correlation coefficient for each class showed a strong linear relationship between SP and faculty assessment scores. The associations between SP and faculty assessment scores in the history, physical examination, and combined history and physical examination components for the 2016 class (0.706, 0.925, and 0.911, respectively) were found to be stronger than those for the 2015 class (0.697, 0.791, and 0.791, respectively). This study indicated that there are strong associations between the assessment scores of trained SPs and faculty for the history, physical examination, and combined history and physical examination components of second-year SPAL activity for podiatric medical students.

    The objective structured examination is one of the most valid, reliable, and effective tools for assessing clinical and communication skills, often by use of standard patients (SPs). SPs can also be assessors of those skills. One of the crucial areas when utilizing SP-based assessment is the quality and consistency assurance of their portrayal of the case and their ability to fill in checklists in an adequate way. The aim of this study was to assess the validity and reliability of SPs' ability to assess students' communication skill via a Calgary-Cambridge checklist. This cross-sectional and correlational study was conducted at the Tehran University of Medical Science. We first analyzed validity; the criterion validity of the SPs' filling in the checklists was assessed through determining the correlation between the SPs' completed checklists and the checklists filled in by three physician raters individually and then reproducibility: it was assessed by a test-retest approach inter-rater reliability. The mean correlation for assessing the validity of SPs' completed checklists by individual SPs was 0.81. The inter-rater reliability was calculated by kappa coefficient, and the total correlation among the three raters was 0.85. The reliability of the test-retest approach showed no significant differences between the test and re-test results. The increased number of medical students and different faculties' responsibilities such as doing educational, research, and health services duties assessing medical student communication skills is a complex issue. The results of our study showed that trained SPs can be used as a valid tool to assess medical students' communication skills, which is also more cost effective and reduces work load of medical faculties.

    Over the past decade, a variety of MRI methods have been developed and applied to many kidney diseases. These MRI techniques show great promise, enabling the noninvasive assessment of renal structure, function and injury in individuals. This review will highlight the current applications of functional MRI techniques for the assessment of renal disease and discuss future directions. Many pathological (functional and structural) changes or factors in renal disease can be assessed by advanced MRI techniques. These include renal vascular structure and function (contrast-enhanced MRI, arterial spin labelling), tissue oxygenation (blood oxygen level dependent MRI), renal tissue injury and fibrosis (diffusion or magnetization transfer imaging, magnetic resonance elastography), renal metabolism (chemical exchange saturation transfer, spectroscopic imaging), nephron endowment (cationic-contrast imaging), sodium concentration (23Na-MRI) and molecular events (targeted-contrast imaging). Current advances in MRI techniques have enabled the noninvasive investigation of renal disease. Further development, evaluation and application of the MRI techniques should facilitate better understanding and assessment of renal disease, and the development of new imaging biomarkers, enabling the intensified treatment of high-risk populations and a more rapid interrogation of novel therapeutic agents and protocols.

    Many developing countries have limited capacity to adequately assess and manage health impacts associated with environmental change. In Mongolia, methodologies to introduce health impact assessment (HIA) as part of the environmental impact assessment (EIA) process have been investigated, and a mechanism to incorporate HIA into the current EIA process is proposed. Some challenges to the implementation of HIA are discussed. The country is now in a position to incorporate HIA as part of the approvals process for development projects. Given the recent growth in population, industrial development, and urbanization together with the interest from international mining companies in the resources of the country, it is important for Mongolia to have such tools in place in order to take advantage of economic growth while improving health and well-being outcomes for the population. © 2012 APJPH.

    Standard postharvest unit operations that rely on copious water contact, such as fruit unloading and washing, approach the criteria for a true critical control point in fresh tomato production. Performance data for approved sanitizers that reflect commercial systems are needed to set standards for audit compliance. This study was conducted to evaluate the efficacy of chlorine dioxide (ClO(2)) for water disinfection as an objective assessment of recent industry-adopted standards for dump tank and flume management in fresh tomato packing operations. On-site assessments were conducted during eight temporally distinct shifts in two Florida packinghouses and one California packinghouse. Microbiological analyses of incoming and washed fruit and dump and flume system water were evaluated. Water temperature, pH, turbidity, conductivity, and oxidation-reduction potential (ORP) were monitored. Reduction in populations of mesophilic and coliform bacteria on fruit was not significant, and populations were significantly higher (P Water temperature varied during daily operations, but pH and ORP mostly remained constant. The industry standard positive temperature differential of 5.5°C between water and fruit pulp was not maintained in tanks during the full daily operation. ORP values were significantly higher in the flume than in the dump tank. A positive correlation was found between ORP and temperature, and negative correlations were found between ORP and turbidity, total mesophilic bacteria, and coliforms. This study provides in-plant data indicating that ClO(2) can be an effective sanitizer in flume and spray-wash systems, but current operational limitations restrict its performance in dump tanks. Under current conditions, ClO(2) alone is unlikely to allow the fresh tomato industry to meet its microbiological quality goals under typical commercial conditions.

    To evaluate the diagnostic capability of a smartphone handset compared with a standard office computer workstation for teleophthalmology fundus photo assessments of diabetic retinopathy. Eligible, consenting participants' fundus images were acquired using a non-mydriatic camera. These images along with other medical data were transmitted 20 miles away through the Internet (gold standard) and also through an iPhone(®) (Apple, Cupertino, CA) to two ophthalmologists, who independently compared the images. The κ coefficient between the gold standard workstation display and iPhone images to detect retinopathy-related changes for both readers was more than 0.9. The image quality of the iPhone was scored high by the ophthalmologists. Ophthalmic images transmitted through both smartphone and Internet techniques match well with each other. Despite current limitations, smartphones could represent as a tool for fundus photo assessments of diabetic retinopathy. Further studies are needed to investigate the economic and clinical feasibility of smartphones in ophthalmology.

    Measuring knee range of motion (ROM) is an important assessment for the outcomes of total knee arthroplasty. Recent technological advances have led to the development and use of accelerometer-based smartphone applications to measure knee ROM. The purpose of this study was to develop, standardize, and validate methods of utilizing smartphone accelerometer technology compared to radiographic standards, visual estimation, and goniometric evaluation. Participants used visual estimation, a long-arm goniometer, and a smartphone accelerometer to determine range of motion of a cadaveric lower extremity; these results were compared to radiographs taken at the same angles. The optimal smartphone position was determined to be on top of the leg at the distal femur and proximal tibia location. Between methods, it was found that the smartphone and goniometer were comparably reliable in measuring knee flexion (ICC=0.94; 95% CI: 0.91-0.96). Visual estimation was found to be the least reliable method of measurement. The results suggested that the smartphone accelerometer was non-inferior when compared to the other measurement techniques, demonstrated similar deviations from radiographic standards, and did not appear to be influenced by the person performing the measurements or the girth of the extremity.

    A study of the transport and loss of ions in the earth's quiet time ring current, in which the standard radial diffusion model developed for the high-energy radiation belt particles is compared with the measurements of the lower-energy ring current ions, is presented. The data set provides ionic composition information in an energy range that includes the bulk of the ring current energy density, 1-300 keV/e. Protons are found to dominate the quiet time energy density at all altitudes, peaking near L of about 4 at 60 keV/cu cm, with much smaller contributions from O(+) (1-10 percent), He(+) (1-5 percent), and He(2+) (less than 1 percent). A minimization procedure is used to fit the amplitudes of the standard electric radial diffusion coefficient, yielding 5.8 x 10 exp -11 R(E-squared)/s. Fluctuation ionospheric electric fields are suggested as the source of the additional diffusion detected.

  3. Including Alternative Resources in State Renewable Portfolio Standards: Current Design and Implementation Experience

    2012-11-01

    Currently, 29 states, the District of Columbia, and Puerto Rico have instituted a renewable portfolio standard (RPS). An RPS sets a minimum threshold for how much renewable energy must be generated in a given year. Each state policy is unique, varying in percentage targets, timetables, and eligible resources. This paper examines state experience with implementing renewable portfolio standards that include energy efficiency, thermal resources, and non-renewable energy and explores compliance experience, costs, and how states evaluate, measure, and verify energy efficiency and convert thermal energy. It aims to gain insights from the experience of states for possible federal clean energy policy as well as to share experience and lessons for state RPS implementation.

    It is difficult to accurately assess and differentially diagnose the anxiety disorders. The current system of assessment relies heavily on the subjective measures of client self-report, clinical observation, and clinical judgment. Fortunately, recent technological advances may enable practitioners to utilize objective, biobehavioral measures of assessment in a clinical setting. The current body of literature on two of these biobehavioral tools (eye-tracking and electrocardiogram devices) is promising, but more validation and standardization research is needed to maximize the utility of these devices. Eye-tracking devices are uniquely capable of providing data that can be used to differentially diagnose anxiety disorders from both other commonly comorbid and misdiagnosed disorders. Both eye-tracking and electrocardiogram devices are able to provide change-sensitive assessment information. This objective, real-time feedback can assist clinicians and researchers in assessing treatment efficacy and symptom fluctuation. Recently developed wearable and highly portable electrocardiogram devices, like the wearable fitness and behavior tracking devices used by many consumers, may be particularly suited for providing this feedback to clinicians. Utilizing these biobehavioral devices would supply an objective, dimensional component to the current categorical diagnostic assessment system. We posit that if adequate funding and attention are directed at this area of research, it could revolutionize diagnostic and on-going assessment practices and, in doing so, bring the field of diagnosis out of the 20th century.

  6. Development of the Test Of Astronomy STandards (TOAST) Assessment Instrument

    Slater, Timothy F.; Slater, S. J.

    2008-05-01

    Considerable effort in the astronomy education research (AER) community over the past several years has focused on developing assessment tools in the form of multiple-choice conceptual diagnostics and content knowledge surveys. This has been critically important in advancing the AER discipline so that researchers could establish the initial knowledge state of students as well as to attempt measure some of the impacts of innovative instructional interventions. Unfortunately, few of the existing instruments were constructed upon a solid list of clearly articulated and widely agreed upon learning objectives. This was not done in oversight, but rather as a result of the relative youth of AER as a discipline. Now that several important science education reform documents exist and are generally accepted by the AER community, we are in a position to develop, validate, and disseminate a new assessment instrument which is tightly aligned to the consensus learning goals stated by the American Astronomical Society - Chair's Conference on ASTRO 101, the American Association of the Advancement of Science's Project 2061 Benchmarks, and the National Research Council's National Science Education Standards. In response, researchers from the Cognition in Astronomy, Physics and Earth sciences Research (CAPER) Team at the University of Wyoming's Science & Math Teaching Center (UWYO SMTC) have designed a criterion-referenced assessment tool, called the Test Of Astronomy STandards (TOAST). Through iterative development, this instrument has a high degree of reliability and validity for instructors and researchers needing information on students’ initial knowledge state at the beginning of a course and can be used, in aggregate, to help measure the impact of course-length duration instructional strategies for courses with learning goals tightly aligned to the consensus goals of our community.

  7. SECOND LANGUAGE VOCABULARY ASSESSMENT: CURRENT PRACTICES AND NEW DIRECTIONS

    Directory of Open Access Journals (Sweden)

    John Read

    2007-12-01

    Full Text Available This paper surveys some current developments in second language vocabulary assessment, with particular attention to the ways in which computer corpora can provide better quality information about the frequency of words and how they are used in specific contexts. The relative merits of different word lists are discussed, including the Academic Word List and frequency lists derived from the British National Corpus. Word frequency data is needed for measures of vocabulary size, such as the Yes/No format, which is being developed and used for a variety of purposes. The paper also reviews work on testing depth of knowledge of vocabulary, where rather less progress has been made, both in defining depth as a construct and in developing tests for practical use. Another important perspective is the use of vocabulary within particular contexts of use or registers, and recent corpus research is extending our understanding of the lexical features of academic registers. This provides a basis for assessing learners’ ability to deploy their vocabulary knowledge effectively for functional communication in specific academic contexts. It is concluded that, while current tests of vocabulary knowledge are valuable for certain purposes, they need to be complemented by more contextualised measures of vocabulary use.

    The circulation of the travelling standards in the CIPM key comparison CCEM-K12 of AC-DC current transfer difference began in March 2005 and was completed in April 2007. The travelling standards were lost on their way from the last participant to the pilot laboratory. Since, prior to their disappearance, the travelling standards exhibited exceptional stability, the CCEM Working Group on Low-Frequency Quantities decided in June 2008 to accept the results of the comparison as valid without the final measurement by the pilot laboratory. The AC-DC transfer differences of the travelling standards have been measured at 10 mA and 5 A, and at the frequencies 10 Hz, 55 Hz, 1 kHz, 10 kHz, 20 kHz, 50 kHz and 100 kHz. The key comparison reference values were calculated as the weighted means of the results of the National Metrology Institutes (NMIs) with independent realizations of primary standards and low reported uncertainties. The degrees of equivalence relative to the key comparison reference values, as well as between pairs of NMIs, have been determined for the measurement points and show very good agreement. All but three of the calculated degrees of equivalence relative to the key comparison reference values are within the limits of the expanded uncertainties. Main text.

    Accurate islet quantification has proven difficult to standardize in a good manufacturing practices (GMP) approved manner. The influence of assessment variables from both manual and computer-assisted digital image analysis (DIA) methods were compared using calibrated, standardized microspheres or islets alone. Additionally, a mixture of microspheres and exocrine tissue was used to evaluate the variability of both the current, internationally recognized, manual method and a novel GMP-friendly purity- and volume-based method (PV) evaluated by DIA in a semiclosed, culture bag system. Computer-assisted DIA recorded known microsphere size distribution and quantities accurately. By using DIA to evaluate islets, the interindividual manually evaluated percent coefficients of variation (CV%; n=14) were reduced by almost half for both islet equivalents (IEs; 31% vs. 17%, P=0.002) and purity (20% vs. 13%, P=0.033). The microsphere pool mixed with exocrine tissue did not differ from expected IE with either method. However, manual IE resulted in a total CV% of 44.3% and a range spanning 258 k IE, whereas PV resulted in CV% of 10.7% and range of 60 k IE. Purity CV% for each method were similar approximating 10.5% and differed from expected by +7% for the manual method and +3% for PV. The variability of standard counting methods for islet samples and clinical quantities of microspheres mixed with exocrine tissue were reduced with DIA. They were reduced even further by use of a semiclosed bag system compared with standard manual counting, thereby facilitating the standardization of islet evaluation according to GMP standards.

    The aim of this study was to describe the current regulatory environment in Greece to evaluate the potential introduction of health technology assessment (HTA) for medicinal products for human use. Data sources consist of national legislation on pricing and reimbursement of health technologies to identify the potential need of establishing HTA and its relevant structure. The pricing procedure regarding medicinal products for human use is based on an external reference pricing mechanism which considers the average of the three lowest Euorpean Union prices. Currently, a formal HTA procedure has not been applied in Greece, and the only prerequisite used for the reimbursement of medicinal products for human use is their inclusion in the Positive Reimbursement List. To restrict pharmaceutical expenditure, a variety of measures-such as clawback mechanisms, rebates, monthly budget caps per physician, generics penetration targeting-have been imposed, aiming mainly to regulate the price level rather than control the introduction of medicinal products for human use in the Greek pharmaceutical market. Greece has the opportunity to rapidly build capacity, implement, and take advantage of the application of HTA mechanisms by clearly defining the goals, scope, systems, context, stakeholders, and methods that will be involved in the local HTA processes, taking into account the country's established e-prescription system and the recently adapted legislative framework.

    The increased popularity of commercially available 3-dimensional human skin equivalents in recent years has allowed for assessment of melanogenesis modulated by compounds topically applied to the skin or directly incorporated from the medium. These skin equivalents provide a suitable model for elucidating the mechanisms of action of various factors that modulate skin pigmentation or other properties of the skin. As such, researchers need to objectively quantify cutaneous responses at the macroscopic level. A simple method to standardize macrophotography images is reported that can quantify cutaneous responses in human skin equivalents of Asian, Black or African American, and Caucasian or White racial/ethnic origin. Macrophotographs are analyzed using the Commission Internationale de l’Eclairage L*a*b* color space system in combination with a personal computer and image editing software. Pigmentation changes monitored over a 9 day period showed a high correlation with melanin content evaluated in Fontana-Masson stained sections. These results indicate the feasibility of using a macrophotography setup in a sterile tissue culture environment to objectively assess in vitro cutaneous responses in human skin equivalents. This serves as an adjunct tool to biochemical and morphological methods to effectively quantify changes in pigmentation over time. PMID:19320841

  14. Standardization of figures and assessment procedures for DTM verticalaccuracy

    Full Text Available Digital Terrain Models (DTMs are widely used in many sectors. They play a key role in hydrological risk prevention, risk mitigation and numeric simulations. This paper deals with two questions: (i when it is stated that a DTM has a given vertical accuracy, is this assertion univocal? (ii when DTM vertical accuracy is assessed by means of checkpoints, does their location influence results? First, the paper illustrates that two vertical accuracy definitions are conceivable: Vertical Accuracy at the Nodes (VAN, the average vertical distance between the model and the terrain, evaluated at the DTM's nodes and Vertical Accuracy at the interpolated Points (VAP, in which the vertical distance is evaluated at the generic points. These two quantities are not coincident and, when they are calculated for the same DTM, different numeric values are reached. Unfortunately, the two quantities are often interchanged, but this is misleading. Second, the paper shows a simulated example of a DTM vertical accuracy assessment, highlighting that the checkpoints’ location plays a key role: when checkpoints coincide with the DTM nodes, VAN is estimated; when checkpoints are randomly located, VAP is estimated, instead. Third, an in-depth, theoretical characterization of the two considered quantities is performed, based on symbolic computation, and suitable standardization coefficients are proposed. Finally, our discussion has a well-defined frame: it doesn't deal with all the items of the DTM vertical accuracy budget, which would require a much longer essay, but only with one, usually called fundamental vertical accuracy.

    Full Text Available South Africa’s performance in international benchmark tests is a major cause for concern amongst educators and policymakers, raising questions about the effectiveness of the curriculum reform efforts of the democratic era. The purpose of the study reported in this article was to investigate the degree of alignment between the TIMSS 2003 Grade 8 Mathematics assessment frameworks and the Revised National Curriculum Statements (RNCS assessment standards for Grade 8 Mathematics, later revised to become the Curriculum and Assessment Policy Statements (CAPS. Such an investigation could help to partly shed light on why South African learners do not perform well and point out discrepancies that need to be attended to. The methodology of document analysis was adopted for the study, with the RNCS and the TIMSS 2003 Grade 8 Mathematics frameworks forming the principal documents. Porter’s moderately complex index of alignment was adopted for its simplicity. The computed index of 0.751 for the alignment between the RNCS assessment standards and the TIMSS assessment objectives was found to be significantly statistically low, at the alpha level of 0.05, according to Fulmer’s critical values for 20 cells and 90 or 120 standard points. The study suggests that inadequate attention has been paid to the alignment of the South African mathematics curriculum to the successive TIMSS assessment frameworks in terms of the cognitive level descriptions. The study recommends that participation in TIMSS should rigorously and critically inform ongoing curriculum reform efforts.

    Drought is a critical issue, and it has a pressing, negative impact on agriculture, ecosystems, livelihoods, food security, and sustainability. The problem has been studied globally, but its regional or even local dimension is sometimes overlooked. Local-level drought assessment is necessary for developing adaptation and mitigation strategies for that particular region. Keeping this in understanding, an attempt was made to create a detailed assessment of drought characteristics at the local scale in Bangladesh. Standardized precipitation evapotranspiration (SPEI) is a new drought index that mainly considers the rainfall and evapotranspiration data set. Globally, SPEI has become a useful drought index, but its local scale application is not common. SPEI base (0.5° grid data) for 110 years (1901-2011) was utilized to overcome the lack of long-term climate data in Bangladesh. Available weather data (1955-2011) from Bangladesh Meteorology Department (BMD) were analyzed to calculate SPEI weather station using the SPEI calculator. The drivers for climate change-induced droughts were characterized by residual temperature and residual rainfall data from different BMD stations. Grid data (SPEI base ) of 26 stations of BMD were used for drought mapping. The findings revealed that the frequency and intensity of drought are higher in the northwestern part of the country which makes it vulnerable to both extreme and severe droughts. Based on the results, the SPEI-based drought intensity and frequency analyses were carried out, emphasizing Rangpur (northwest region) as a hot spot, to get an insight of drought assessment in Bangladesh. The findings of this study revealed that SPEI could be a valuable tool to understand the evolution and evaluation of the drought induced by climate change in the country. The study also justified the immediate need for drought risk reduction strategies that should lead to relevant policy formulations and agricultural innovations for developing

    EOS is a 2D/3D muscle skeletal diagnostic imaging system. The device has been developed to produce a high quality 2D, full body radiographs in standing, sitting and squatting positions. Three dimensional images can be reconstructed via sterEOS software. This Health Technology Assessment study aimed to investigate efficacy, effectiveness and cost-effectiveness of new emerged EOS imaging system in comparison with conventional x-ray radiographic techniques. All cost and outcome data were assessed from Iran's Ministry of Health Perspective. Data for clinical effectiveness was extracted using a rigorous systematic review. As clinical outcomes the rate of x-ray emission and related quality of life were compared with Computed Radiography (CR) and Digital Radiography (DR). Standard costing method was conducted to find related direct medical costs. In order to examine robustness of the calculated Incremental Cost Effectiveness Ratios (ICERs) we used two-way sensitivity analysis. GDP Per capita of Islamic Republic of Iran (2012) adopted as cost-effectiveness threshold. Review of related literature highlighted the lack of rigorous evidence for clinical outcomes. Ultra low dose EOS imaging device is known as a safe intervention because of FDA, CE and CSA certificates. The rate of emitted X-ray was 2 to 18 fold lower for EOS compared to the conventional techniques (p<0.001). The Incremental Cost Effectiveness Ratio for EOS relative to CR calculated $50706 in baseline analysis (the first scenario) and $50714, $9446 respectively for the second and third scenarios. Considering the value of neither $42146 as upper limit, nor the first neither the second scenario could pass the cost-effectiveness threshold for Iran. EOS imaging technique might not be considered as a cost-effective intervention in routine practice of health system, especially within in-patient wards. Scenario analysis shows that, only in an optimum condition such as lower assembling costs and higher utilization rates

    Standardizing scoring reduces variability and increases accuracy. A detailed scoring and training method for the Fugl-Meyer motor assessment (FMA) is described and assessed, and implications for clinical trials considered. A standardized FMA scoring approach and training materials were assembled, including a manual, scoring sheets, and instructional video plus patient videos. Performance of this approach was evaluated for the upper extremity portion. Inter- and intrarater reliability in 31 patients were excellent (intraclass correlation coefficient = 0.98-0.99), validity was excellent (r = 0.74-0.93, P versus 0.9 ± 4.9 points posttraining. The current approach was implemented without incident into training for a phase II trial. Among 66 patients treated with robotic therapy, change in FMA was smaller (P ≤ .01) at the high and low ends of baseline FMA scores. Training with the current method improved accuracy, and reduced variance, of FMA scoring; the 20% FMA variance reduction with training would decrease sample size requirements from 137 to 88 in a theoretical trial aiming to detect a 7-point FMA difference. Minimal detectable change was much smaller than FMA minimal clinically important difference. The variation in FMA gains in relation to baseline FMA suggests that future trials consider a sliding outcome approach when FMA is an outcome measure. The current training approach may be useful for assessing motor outcomes in restorative stroke trials.

    Several studies have demonstrated the importance of environmental conditions in the radiology reporting environment, with many indicating that incorrect parameters could lead to error and misinterpretation. Literature is available with recommendations as to the levels that should be achieved in clinical practice, but evidence of adherence to these guidelines in radiology reporting environments is absent. This study audited the reporting environments of four teleradiologist and eight hospital based radiology reporting areas. This audit aimed to quantify adherence to guidelines and identify differences in the locations with respect to layout and design, monitor distance and angle as well as the ambient factors of the reporting environments. In line with international recommendations, an audit tool was designed to enquire in relation to the layout and design of reporting environments, monitor angle and distances used by radiologists when reporting, as well as the ambient factors such as noise, light and temperature. The review of conditions were carried out by the same independent auditor for consistency. The results obtained were compared against international standards and current research. Each radiology environment was given an overall compliance score to establish whether or not their environments were in line with recommended guidelines. Poor compliance to international recommendations and standards among radiology reporting environments was identified. Teleradiology reporting environments demonstrated greater compliance than hospital environments. The findings of this study identified a need for greater awareness of environmental and perceptual issues in the clinical setting. Further work involving a larger number of clinical centres is recommended.

  20. Assessing the performance of standard methods to predict the standard uncertainty of air quality data having incomplete time coverage.

    2014-07-01

    As a result of the complex nature of operating multi-station national air quality networks it is rare that complete data sets are produced from these networks. The reliance of most air quality legislation on the assessment of measured annual average concentrations against target or limit concentrations necessitates the use of methods to calculate an annual average value and the uncertainty in this value in the absence of a complete data set for the year in question. Standard procedures exist for performing these calculations, but it is not clear how effective these are when data having low time resolution are collected and missing data accounts for large periods of the year. This paper investigates the influence of these deficiencies using data from UK air quality networks in the form of monthly average concentrations for polycyclic aromatic hydrocarbons and for metals in the PM10 phase of ambient air. Whilst the standard methods currently employed produce good results on average, for individual cases the uncertainty in the annual average calculated when data is missing may be appreciably different from that obtained when full knowledge of the distribution of the data is known. These effects become more apparent as the quantity of missing data increases.

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

    Radiographic assessment of skeletal age in pediatric patients is a common practice among orthopaedic surgeons. Current methods of assessment remain labor intensive and require special resources. This study sought to investigate a novel, abridged method of bone age assessment that may serve as a simpler and more efficient alternative to the current standard. A shorthand bone age (SBA) method developed at our institution was compared against the Greulich and Pyle method from which it was derived. Standard left hand bone age radiographs of 140 male and 120 female patients, previously assigned skeletal ages ranging from 12.5 to 16 years in males and 10 to 16 years in females by musculoskeletal radiologists using the Greulich and Pyle radiographic atlas, were read using the shorthand method by 3 attending pediatric orthopaedic surgeons and an orthopaedic surgery resident. The shorthand method utilizes a single, univariable criterion for each age, rather than a multivariable subjective comparison to a radiographic atlas. All reviewers were blinded to the original bone age determination. Interobserver reliability, intraobserver reliability, and agreement with the previous records utilizing the atlas were calculated using weighted κ. The SBA method readings demonstrated substantial agreement with readings by the Greulich and Pyle atlas, demonstrating weighted κ values ranging from 0.71 to 0.75. The SBA method also demonstrated substantial to almost perfect interobserver and intraobserver reliability, with values ranging from 0.77 to 0.87 and from 0.87 to 0.95, respectively. These results are comparable or superior to previous reports which investigate the validity and reliability of other skeletal age assessment tools. The SBA assessment tool offers a simple and efficient alternative to current methods. Diagnostic study, level III.

    Density Functional Theory (DFT) based Equation of State (EOS) construction is a prominent part of Sandia’s capabilities to support engineering sciences. This capability is based on augmenting experimental data with information gained from computational investigations, especially in those parts of the phase space where experimental data is hard, dangerous, or expensive to obtain. A key part of the success of the Sandia approach is the fundamental science work supporting the computational capability. Not only does this work enhance the capability to perform highly accurate calculations but it also provides crucial insight into the limitations of the computational tools, providing high confidence in the results even where results cannot be, or have not yet been, validated by experimental data. This report concerns the key ingredient of projector augmented-wave (PAW) potentials for use in pseudo-potential computational codes. Using the tools discussed in SAND2012-7389 we assess the standard Vienna Ab-initio Simulation Package (VASP) PAWs for Molybdenum.

    Renewable portfolio standards (RPS) exist in 29 US states and the District of Columbia. This article summarizes the first national-level, integrated assessment of the future costs and benefits of existing RPS policies; the same metrics are evaluated under a second scenario in which widespread expansion of these policies is assumed to occur. Depending on assumptions about renewable energy technology advancement and natural gas prices, existing RPS policies increase electric system costs by as much as 31 billion, on a present-value basis over 2015-2050. The expanded renewable deployment scenario yields incremental costs that range from 23 billion to 194 billion, depending on the assumptions employed. The monetized value of improved air quality and reduced climate damages exceed these costs. Using central assumptions, existing RPS policies yield 97 billion in air-pollution health benefits and 161 billion in climate damage reductions. Under the expanded RPS case, health benefits total 558 billion and climate benefits equal 599 billion. These scenarios also yield benefits in the form of reduced water use. RPS programs are not likely to represent the most cost effective path towards achieving air quality and climate benefits. Nonetheless, the findings suggest that US RPS programs are, on a national basis, cost effective when considering externalities.

    Despite increasing emphasis on the implementation of evidence-based treatments in community service settings, little attention has been paid to supporting the use of evidence-based assessment (EBA) methods and processes, a parallel component of evidence-based practice. Standardized assessment (SA) tools represent a key aspect of EBA and are central to data-driven clinical decision making. The current study evaluated the impact of a statewide training and consultation program in a common elements approach to psychotherapy. Practitioner attitudes toward, skill applying, and use of SA tools across four time points (pre-training, post-training, post-consultation, and follow-up) were assessed. Results indicated early increases in positive SA attitudes, with more gradual increases in self-reported SA skill and use. Implications for supporting the sustained use of SA tools are discussed, including the use of measurement feedback systems, reminders, and SA-supportive supervision practices.

    With its transparent orthography, Standard Indonesian is spoken by over 160 million inhabitants and is the primary language of instruction in education and the government in Indonesia. An assessment battery of reading and reading-related skills was developed as a starting point for the diagnosis of dyslexia in beginner learners. Founded on the International Dyslexia Association's definition of dyslexia, the test battery comprises nine empirically motivated reading and reading-related tasks assessing word reading, pseudoword reading, arithmetic, rapid automatized naming, phoneme deletion, forward and backward digit span, verbal fluency, orthographic choice (spelling), and writing. The test was validated by computing the relationships between the outcomes on the reading-skills and reading-related measures by means of correlation and factor analyses. External variables, i.e., school grades and teacher ratings of the reading and learning abilities of individual students, were also utilized to provide evidence of its construct validity. Four variables were found to be significantly related with reading-skill measures: phonological awareness, rapid naming, spelling, and digit span. The current study on reading development in Standard Indonesian confirms findings from other languages with transparent orthographies and suggests a test battery including preliminary norm scores for screening and assessment of elementary school children learning to read Standard Indonesian.

  19. Environmental assessment for the Consumer Products Efficiency Standards program

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-23

    The Energy Policy and Conservation Act of 1975 as amended by the National Energy Conservation Policy Act of 1978, requires the DOE to prescribe energy efficiency standards for thirteen consumer products. The Consumer Products Efficiency Standards (CPES) program covers the following products: refrigerators and refrigerator-freezers; freezers;clothes dryers;water heaters; room air conditioners; home heating equipment (not including furnaces); kitchen ranges and ovens; central air conditioners (cooling and heat pumps); furnaces; dishwashers; television sets; clothes washers; and humidifiers and dehumidifiers. DOE is proposing two sets of standards for all thirteen consumer products: intermediate standards to become effective in 1981 for the first nine products and in 1982 for the second four products, and final standards to become effective in 1986 and 1987, respectively. The final standards are more restrictive than the intermediate standards and will provide manufacturers with the maximum time permitted under the Act to plan and develop extensive new lines of efficient consumer products. The final standards proposed by DOE require the maximum improvements in efficiency which are technologically feasible and economically justified, as required by Section 325(c) of EPCA. The thirteen consumer products account for approximately 90% of all the energy consumed in the nation's residences, or more than 20% of the nation's energy needs. Increases in the energy efficiency of these consumer products can help to narrow the gap between the nation's increasing demand for energy and decreasing supplies of domestic oil and natural gas. Improvements in the efficiency of consumer products can thus help to solve the nation's energy crisis.

    Hepatic encephalopathy (HE) is defined as a metabolically induced, potentially reversible, functional disturbance of the brain that may occur in acute or chronic liver disease. Standardized nomenclature has been proposed but a standardized approach to the treatment, particularly of persistent, episodic and recurrent encephalopathy associated with liver cirrhosis has not been proposed. This review focuses on the pathogenesis and treatment of HE in patients with cirrhosis. The pathogenesis and treatment of hepatic encephalopathy in fulminant hepatic failure is quite different and is reviewed elsewhere.

  2. Eddy heat flux across the Antarctic Circumpolar Current estimated from sea surface height standard deviation

    Foppert, Annie; Donohue, Kathleen A.; Watts, D. Randolph; Tracey, Karen L.

    2017-08-01

    Eddy heat flux (EHF) is a predominant mechanism for heat transport across the zonally unbounded mean flow of the Antarctic Circumpolar Current (ACC). Observations of dynamically relevant, divergent, 4 year mean EHF in Drake Passage from the cDrake project, as well as previous studies of atmospheric and oceanic storm tracks, motivates the use of sea surface height (SSH) standard deviation, H*, as a proxy for depth-integrated, downgradient, time-mean EHF (>[EHF>¯>]) in the ACC. Statistics from the Southern Ocean State Estimate corroborate this choice and validate throughout the ACC the spatial agreement between H* and >[EHF>¯>] seen locally in Drake Passage. Eight regions of elevated >[EHF>¯>] are identified from nearly 23.5 years of satellite altimetry data. Elevated cross-front exchange usually does not span the full latitudinal width of the ACC in each region, implying a hand-off of heat between ACC fronts and frontal zones as they encounter the different >[EHF>¯>] hot spots along their circumpolar path. Integrated along circumpolar streamlines, defined by mean SSH contours, there is a convergence of ∮>[EHF>¯>] in the ACC: 1.06 PW enters from the north and 0.02 PW exits to the south. Temporal trends in low-frequency [EHF] are calculated in a running-mean sense using H* from overlapping 4 year subsets of SSH. Significant increases in downgradient [EHF] magnitude have occurred since 1993 at Kerguelen Plateau, Southeast Indian Ridge, and the Brazil-Malvinas Confluence, whereas the other five >[EHF>¯>] hot spots have insignificant trends of varying sign.

    Full Text Available This paper reports the results of a phenomenographic study on the different ways that secondary students understood and utilized student self-assessment and how various ego types could affect the accuracy of self-assessment. The study sought to contribute to the growing literature which recognizes the critical role that students play in assessment processes, and in particular the different roles that they assume in student self-assessment. The results of the study provide insights into how different students experience self-assessment by articulating the variation in the perception and purposes of assessing one's own learning. This variation is depicted as a hierarchy of logically related students' conceptions of self-assessment.

    Remington, Benjamin C.

    2017-09-01

    Risk analysis is a three part, interactive process that consists of a scientific risk assessment, a risk management strategy and an exchange of information through risk communication. Quantitative risk assessment methodologies are now available and widely used for assessing risks regarding the unintentional consumption of major, regulated allergens but new or modified proteins can also pose a risk of de-novo sensitization. The risks due to de-novo sensitization to new food allergies are harder to quantify. There is a need for a systematic, comprehensive battery of tests and assessment strategy to identify and characterise de-novo sensitization to new proteins and the risks associated with them. A risk assessment must be attuned to answer the risk management questions and needs. Consequently, the hazard and risk assessment methods applied and the desired information are determined by the requested outcome for risk management purposes and decisions to be made. The COST Action network (ImpARAS, www.imparas.eu) has recently started to discuss these risk management criteria from first principles and will continue with the broader subject of improving strategies for allergen risk assessment throughout 2016-2018/9.

    2015-07-01

    Full Text Available The authors of this qualitative study set out to investigate self-assessment practices within the library profession. The researchers conducted semi-structured interviews with a purposeful sample of nine librarians coming from a range of library settings and possessing a diversity of library experience. Interviews were then transcribed and coded in NVIVO to identify emergent themes. This paper details some of the results of that study, highlighting motivations, limitations, and strategies with regard to self-assessment. The findings present a summary of a range of approaches to the practice of assessment as reported by the interviewees. One area of possible growth for our profession, as highlighted by the findings, is in the development of peer networks as a support for the individual practice of self-assessment. While the results of this small case study cannot be generalized, the authors hope these preliminary findings can open up the conversation around self-assessment both for individual librarians and for those librarians and managers working to shape their workplace culture.

    Although idiosyncratic adverse drug reactions are rare, they are still a major concern to patient safety. Reactive metabolites are widely accepted as playing a pivotal role in the pathogenesis of idiosyncratic adverse drug reactions. While there are today well established strategies for the risk assessment of stable metabolites within the pharmaceutical industry, there is still no consensus on reactive metabolite risk assessment strategies. This is due to the complexity of the mechanisms of these toxicities as well as the difficulty in identifying and quantifying short-lived reactive intermediates such as reactive metabolites. In this review, reactive metabolite risk and hazard assessment approaches are discussed, and their pros and cons highlighted. We also discuss the nature of idiosyncratic adverse drug reactions, using acetaminophen and nefazodone to exemplify the complexity of the underlying mechanisms of reactive metabolite mediated hepatotoxicity. One of the key gaps moving forward is our understanding of and ability to predict the contribution of immune activation in idiosyncratic adverse drug reactions. Sections are included on the clinical phenotypes of immune mediated idiosyncratic adverse drug reactions and on the present understanding of immune activation by reactive metabolites. The advances being made in microphysiological systems have a great potential to transform our ability to risk assess reactive metabolites, and an overview of the key components of these systems is presented. Finally, the potential impact of systems pharmacology approaches in reactive metabolite risk assessments is highlighted.

    Assessment has become a major aspect of accreditation processes across all of higher education. As the Accreditation Council for Pharmacy Education (ACPE) plans a major revision to the standards for doctor of pharmacy (PharmD) education, an in-depth, scholarly review of the approaches and strategies for assessment in the PharmD program accreditation process is warranted. This paper provides 3 goals and 7 recommendations to strengthen assessment in accreditation standards. The goals include: (1) simplified standards with a focus on accountability and improvement, (2) institutionalization of assessment efforts; and (3) innovation in assessment. Evolving and shaping assessment practices is not the sole responsibility of the accreditation standards. Assessment requires commitment and dedication from individual faculty members, colleges and schools, and organizations supporting the college and schools, such as the American Association of Colleges of Pharmacy. Therefore, this paper also challenges the academy and its members to optimize assessment practices.

    2016-05-15

    In December 2014, unknown hackers hacked internal documents sourced from Korea Hydro and Nuclear Power (KHNP) and those electronic documents were posted five times on a Social Network Service (SNS). The data included personal profiles, flow charts, manuals and blueprints for installing pipes in the nuclear power plant. Although the data were not critical to operation or sabotage of the plant, it threatened people and caused social unrest in Korea and neighboring countries. In December 2015, cyber attack on power grid caused a blackout for hundreds of thousands of people in Ukraine. The power outage was caused by a sophisticated attack using destructive malware called 'BlackEnergy'. Cyber attacks are reality in today's world and critical infrastructures are increasingly targeted. Critical infrastructures, such as the nuclear power plant, need to be proactive and protect the nuclear materials, assets and facilities from potential cyber attacks. The threat assessment document and its detailed procedure are confidential for the State. Nevertheless, it is easy to find cooperation on assessing and evaluating the threats of nuclear materials and facilities with other government departments or agencies including the national police. The NSSC and KINAC also cooperated with the National Intelligence Service (NIS) and National Security Research Institute (NSR). However, robust cyber threat assessment system and regular consultative group should be established with domestic and overseas organization including NIS, NSR, the National Police Agency and the military force to protect and ensure to safety of people, public and environment from rapidly changing and upgrading cyber threats.

    future research directions. First, we found that BC and EC mass concentration in Rome are larger than those measured in similar urban areas across Europe (the urban background mass concentration of eBC in Rome in winter being on average 2.6 ± 2.5 μ g · m − 3 , mean eBC at the peak level hour being 5.2 (95% CI = 5.0–5.5 μ g · m − 3 . Then, we discussed significant variations of carbonaceous aerosol properties occurring with time scales of minutes, and questioned on the data averaging period used in current air quality standard for PM 10 (24-h. Third, we showed that the oxidative potential induced by aerosol depends on particle size and composition, the effects of toxicity being higher with lower mass concentrations and smaller particle size. Albeit this is a preliminary analysis, findings reinforce the need for an urgent update of existing air quality standards for PM 10 and PM 2.5 with regard to particle composition and size distribution, and data averaging period. Our results reinforce existing concerns about the toxicity of carbonaceous aerosols, support the existing evidence indicating that particle size distribution and composition may play a role in the generation of this toxicity, and remark the need to consider a shorter averaging period (<1 h in these new standards.

  20. Assessing children’s competence to consent in research by a standardized tool: a validity study

    Directory of Open Access Journals (Sweden)

    2012-09-01

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

  1. Standardizing Benchmark Dose Calculations to Improve Science-Based Decisions in Human Health Assessments

    Science.gov (United States)

    Wignall, Jessica A.; Shapiro, Andrew J.; Wright, Fred A.; Woodruff, Tracey J.; Chiu, Weihsueh A.; Guyton, Kathryn Z.

    2014-01-01

    Background: Benchmark dose (BMD) modeling computes the dose associated with a prespecified response level. While offering advantages over traditional points of departure (PODs), such as no-observed-adverse-effect-levels (NOAELs), BMD methods have lacked consistency and transparency in application, interpretation, and reporting in human health assessments of chemicals. Objectives: We aimed to apply a standardized process for conducting BMD modeling to reduce inconsistencies in model fitting and selection. Methods: We evaluated 880 dose–response data sets for 352 environmental chemicals with existing human health assessments. We calculated benchmark doses and their lower limits [10% extra risk, or change in the mean equal to 1 SD (BMD/L10/1SD)] for each chemical in a standardized way with prespecified criteria for model fit acceptance. We identified study design features associated with acceptable model fits. Results: We derived values for 255 (72%) of the chemicals. Batch-calculated BMD/L10/1SD values were significantly and highly correlated (R2 of 0.95 and 0.83, respectively, n = 42) with PODs previously used in human health assessments, with values similar to reported NOAELs. Specifically, the median ratio of BMDs10/1SD:NOAELs was 1.96, and the median ratio of BMDLs10/1SD:NOAELs was 0.89. We also observed a significant trend of increasing model viability with increasing number of dose groups. Conclusions: BMD/L10/1SD values can be calculated in a standardized way for use in health assessments on a large number of chemicals and critical effects. This facilitates the exploration of health effects across multiple studies of a given chemical or, when chemicals need to be compared, providing greater transparency and efficiency than current approaches.

    Full Text Available The usability of Web sites and online services is of rising importance. When creating a completely new Web site, qualitative data are adequate for identifying the most usability problems. However, changes of an existing Web site should be evaluated by a quantitative benchmarking process. The proposed paper describes the creation of a questionnaire that allows a quantitative usability benchmarking, i.e. a direct comparison of the different versions of a Web site and an orientation on general standards of usability. The questionnaire is also open for qualitative data. The methodology will be explained by the digital library services of the ZBW.

    Fifteen evidence-based Standards for Psychosocial Care for Children with Cancer and Their Families (Standards) were published in 2015. The Standards cover a broad range of topics and circumstances and require qualified multidisciplinary staff to be implemented. This paper presents data on the availability of psychosocial staff and existing practices at pediatric oncology programs in the United States, providing data that can be used to advocate for expanded services and prepare for implementation of the Standards. Up to three healthcare professionals from 144 programs (72% response rate) participated in an online survey conducted June-December 2016. There were 99 pediatric oncologists with clinical leadership responsibility (Medical Director/Clinical Director), 132 psychosocial leaders in pediatric oncology (Director of Psychosocial Services/Manager/most senior staff member), and 58 administrators in pediatric oncology (Administrative Director/Business Administrator/Director of Operations). The primary outcomes were number and type of psychosocial staff, psychosocial practices, and identified challenges in the delivery of psychosocial care. Over 90% of programs have social workers and child life specialists who provide care to children with cancer and their families. Fewer programs have psychologists (60%), neuropsychologists (31%), or psychiatrists (19%). Challenges in psychosocial care are primarily based on pragmatic issues related to funding and reimbursement. Most participating pediatric oncology programs appear to have at least the basic level of staffing necessary to implement of some of the Standards. However, the lack of a more comprehensive multidisciplinary team is a likely barrier in the implementation of the full set of Standards. © 2017 Wiley Periodicals, Inc.

    Hagen, Neil A; Biondo, Patricia; Stiles, Carla

    2008-08-01

    Cancer pain is highly prevalent and often severe. Fortunately, most cancer pain can be readily managed, with up to 90% of patients responding well to standard interventions. However, breakthrough cancer pain-brief flares of severe pain superimposed on baseline pain-is common, difficult to manage, and often negatively impacts patients' quality of life. Breakthrough cancer pain is traditionally managed with oral, immediate-release opioids. However, because of its sudden onset and severity, oral opioids often fall short of providing adequate control. Research into novel approaches to pain management has identified several innovative strategies for this difficult cancer pain problem. We describe current approaches to assess, define, characterize, and treat breakthrough cancer pain, and summarize recent clinical research on novel agents, novel routes of drug delivery, and other advances in its management.

    1992-12-31

    The Panel on Basic Nuclear Data Compilations believes that it is important to provide the user with an evaluated nuclear database of the highest quality, dependability, and currency. It is also important that the evaluated nuclear data are easily accessible to the user. In the past the panel concentrated its concern on the cycle time for the publication of A-chain evaluations. However, the panel now recognizes that publication cycle time is no longer the appropriate goal. Sometime in the future, publication of the evaluated A-chains will evolve from the present hard-copy Nuclear Data Sheets on library shelves to purely electronic publication, with the advent of universal access to terminals and the nuclear databases. Therefore, the literature cut-off date in the Evaluated Nuclear Structure Data File (ENSDF) is rapidly becoming the only important measure of the currency of an evaluated A-chain. Also, it has become exceedingly important to ensure that access to the databases is as user-friendly as possible and to enable electronic publication of the evaluated data files. Considerable progress has been made in these areas: use of the on-line systems has almost doubled in the past year, and there has been initial development of tools for electronic evaluation, publication, and dissemination. Currently, the nuclear data effort is in transition between the traditional and future methods of dissemination of the evaluated data. Also, many of the factors that adversely affect the publication cycle time simultaneously affect the currency of the evaluated nuclear database. Therefore, the panel continues to examine factors that can influence cycle time: the number of evaluators, the frequency with which an evaluation can be updated, the review of the evaluation, and the production of the evaluation, which currently exists as a hard-copy issue of Nuclear Data Sheets.

    Canada's wind energy industry is experiencing significant growth. Government initiatives such as the wind power production incentive program (WPPI) may result in a cumulative installed wind energy capacity of up to 10,000 MW by 2015. However, the methods used to assess wind farm performance have never been thoroughly investigated in a specifically Canadian context. This project was conducted to provide a more accurate understanding of the limitations of various wind farm performance measuring methods and recommend effective methodologies based on the effect of terrain, the position of the wind turbines, and wind characteristics. The study was conducted at 5 wind farms in various Canadian locations, including Prince Edward Island (PEI). A full year of data for each wind farm was used to determine wind speed, wind direction, temperature, pressure, relative humidity, power, and Nacelle orientation. Various wind resource assessment software programs were analyzed in order to evaluate topography and roughness effects, wake analyses, and to compare results from the models with actual wind speed data. tabs., figs.

    Characterizing and contrasting the current state of affairs concerning patients' rights-associated accreditation standards in a sample of drug-addiction treatment centers in Colombia. This was mixed methodology research (i.e. descriptive and hermeneutic); a pilot sample of 21 drug-addiction treatment centers in Colombia was used for determining the current state of patients' rights accreditation standards. The possible relationship or independence between categorical variables was evaluated by using Fisher's exact test (0.05 significance level). A contrasting documentary review was made at the same time. Drug-addiction treatment centers provided more information for families (95 %) than patients (90 %) or minors (81 %). Possible barriers to gaining access for treatment were being HIV positive (29 %), being part of the LGTB population (14 %) and being female (10 %); religion and ethnicity were not seen as grounds for discrimination or treatment barriers. The patients' rights standards group coincided with Colombia's accreditation system and Joint Commission standards; however, the latter accreditation entity has made significant progress regarding a specific manual for drug-addiction treatment centers. The centers assessed in Colombia had made advances regarding accrediting patients' rights, but such standards require revision for being adapted to international developments and specific matters involved in treating addicts and the specific conditions for institutions dealing with such treatment.

  19. Do Currently Available Blood Glucose Monitors Meet Regulatory Standards? 1-Day Public Meeting in Arlington, Virginia

    2013-01-01

    Blood glucose monitors (BGMs) are approved by regulatory agencies based on their performance during strict testing conducted by their manufacturers. However, after approval, there is uncertainty whether BGMs maintain the accuracy levels that were achieved in the initial data. The availability of inaccurate BGM systems pose a public health problem because their readings serve as a basis for treatment decisions that can be incorrect. Several articles have concluded that BGMs in the marketplace may not consistently provide accurate results in accordance with the regulatory standards that led to approval. To address this growing concern, Diabetes Technology Society organized and conducted a 1-day public meeting on May 21, 2013, in Arlington, VA, presided by its president, David Klonoff, M.D., FACP, Fellow AIMBE, to determine whether BGMs on the market meet regulatory standards. The meeting consisted of four sessions in which Food and Drug Administration diabetes experts as well as leading academic clinicians and clinical chemists participated: (1) How is BGM performance determined? (2) Do approved BGMs perform according to International Organization for Standardization standards? (3) How do approved BGMs perform when used by patients and health care professionals? (4) What could be the consequence of poor BGM performance? PMID:23911191

    Trauzettel-Klosinski, Susanne; Dietz, Klaus

    2012-08-13

    There is a need for standardized texts to assess reading performance, for multiple equivalent texts for repeated measurements, and for texts equated across languages for multi-language studies. Paragraphs are preferable to single sentences for accurate speed measurement. We developed such texts previously in 6 languages. The aim of our current study was to develop texts in more languages for a wide range of countries and users, and to assess the reading speeds of normally-sighted readers. Ten texts were designed for 17 languages each by a linguist who matched content, length, difficulty, and linguistic complexity. The texts then were used to assess reading speeds of 436 normally-sighted native speakers (age 18-35 years, 25 per language, 36 in Japanese), presented at a distance of 40 cm and size 1 M, that is 10-point Times New Roman font. Reading time (aloud) was measured by stopwatch. For all 17 languages, average mean reading speed was 1.42 ± 0.13 texts/min (±SD), 184 ± 29 words/min, 370 ± 80 syllables/min, and 863 ± 234 characters/min. For 14 languages, mean reading time was 68 ms/character (95% confidence interval [CI] 65-71 ms). Our analysis focussed on words per minute. The variability of reading speed within subjects accounts only for an average of 11.5%, between subjects for 88.5%. The low within-subject variability shows the equivalence of the texts. The IReST (second edition) can now be provided in 17 languages allowing standardized assessment of reading speed, as well as comparability of results before and after interventions, and is a useful tool for multi-language studies (for further information see www.amd-read.net).

    2017-09-26

    Pulsed Eddy Current (PEC) sensing is used for Non-Destructive Evaluation (NDE) of the structural integrity of metallic structures in the aircraft, railway, oil and gas sectors. Urban water utilities also have extensive large ferromagnetic structures in the form of critical pressure pipe systems made of grey cast iron, ductile cast iron and mild steel. The associated material properties render NDE of these pipes by means of electromagnetic sensing a necessity. In recent years PEC sensing has established itself as a state-of-the-art NDE technique in the critical water pipe sector. This paper presents advancements to PEC inspection in view of the specific information demanded from water utilities along with the challenges encountered in this sector. Operating principles of the sensor architecture suitable for application on critical pipes are presented with the associated sensor design and calibration strategy. A Gaussian process-based approach is applied to model a functional relationship between a PEC signal feature and critical pipe wall thickness. A case study demonstrates the sensor's behaviour on a grey cast iron pipe and discusses the implications of the observed results and challenges relating to this application.

    1988-01-01

    At present, there is no standardized method for assessing remote memory (RM) for visuospatial information in humans. The Fargo Map Test (FMT) uses knowledge of the locations of geographical features in regions of the country in which subjects currently live and formerly resided to provide a measure of this aspect of RM. Two different formats of the FMT have been developed, which differ in their demands for fine motor skill, ease of scoring, and in the amount and nature of geographical knowledge that can be measured. Preliminary findings suggest that both formats are equally sensitive to the influences of gender and age in normal subjects. Furthermore, knowledge of the geography of regions of prior residence appears to be stable over a period of at least 15 years.

  5. Current methodological issues in the economic assessment of personalized medicine.

    Annemans, Lieven; Redekop, Ken; Payne, Katherine

    2013-01-01

    There is a need for methodological scrutiny in the economic assessment of personalized medicine. In this article, we present a list of 10 specific issues that we argue pose specific methodological challenges that require careful consideration when designing and conducting robust model-based economic evaluations in the context of personalized medicine. Key issues are related to the correct framing of the research question, interpretation of test results, data collection of medical management options after obtaining test results, and expressing the value of tests. The need to formulate the research question clearly and be explicit and specific about the technology being evaluated is essential because various test kits can have the same purpose and yet differ in predictive value, costs, and relevance to practice and patient populations. The correct reporting of sensitivity/specificity, and especially the false negatives and false positives (which are population dependent), of the investigated tests is also considered as a key element. This requires additional structural complexity to establish the relationship between the test result and the consecutive treatment changes and outcomes. This process involves translating the test characteristics into clinical utility, and therefore outlining the clinical and economic consequences of true and false positives and true and false negatives. Information on treatment patterns and on their costs and outcomes, however, is often lacking, especially for false-positive and false-negative test results. The analysis can even become very complex if different tests are combined or sequentially used. This potential complexity can be handled by explicitly showing how these tests are going to be used in practice and then working with the combined sensitivities and specificities of the tests. Each of these issues leads to a higher degree of uncertainty in economic models designed to assess the added value of personalized medicine compared

  6. Genomic resources in fruit plants: an assessment of current status.

    Rai, Manoj K; Shekhawat, N S

    2015-01-01

    The availability of many genomic resources such as genome sequences, functional genomics resources including microarrays and RNA-seq, sufficient numbers of molecular markers, express sequence tags (ESTs) and high-density genetic maps is causing a rapid acceleration of genetics and genomic research of many fruit plants. This is leading to an increase in our knowledge of the genes that are linked to many horticultural and agronomically important traits. Recently, some progress has also been made on the identification and functional analysis of miRNAs in some fruit plants. This is one of the most active research fields in plant sciences. The last decade has witnessed development of genomic resources in many fruit plants such as apple, banana, citrus, grapes, papaya, pears, strawberry etc.; however, many of them are still not being exploited. Furthermore, owing to lack of resources, infrastructure and research facilities in many lesser-developed countries, development of genomic resources in many underutilized or less-studied fruit crops, which grow in these countries, is limited. Thus, research emphasis should be given to those fruit crops for which genomic resources are relatively scarce. The development of genomic databases of these less-studied fruit crops will enable biotechnologists to identify target genes that underlie key horticultural and agronomical traits. This review presents an overview of the current status of the development of genomic resources in fruit plants with the main emphasis being on genome sequencing, EST resources, functional genomics resources including microarray and RNA-seq, identification of quantitative trait loci and construction of genetic maps as well as efforts made on the identification and functional analysis of miRNAs in fruit plants.

  7. Current status and standards for establishment of hemodialysis units in Korea

    Lee, Young-Ki; Kim, Kiwon

    2013-01-01

    The number of hemodialysis patients and dialysis facilities is increasing each year, but there are no surveillance programs validating that the services and equipment of each hemodialysis unit meet specified safety and quality standards. There is a concern that excessive competition and illegal activities committed by some dialysis facilities may violate patients' right to health. Contrastingly, developed countries often have their own survey program to provide initial certification and monitoring to ensure that these clinics continue to meet basic requirements. Because hemodialysis units provide renal replacement therapy to critical patients suffering from severe chronic renal failure, appropriate legal regulation is important for the provision of initial certification and maintenance of facility, equipment, and human resource quality. Therefore, several standards providing minimum requirements for the area of hemodialysis unit, equipment for emergency care, physician and nurse staffs, water purification and quality management are urgently needed.

    2017-12-01

    Full Text Available By studying languages in contact, we can observe one language while revealing hidden features of another. This was the original idea of the two Slovene-Croatian phonetic and phonological bilateral projects, which connected various Slovene and Croatian phonologists. This paper highlights the work of Rastislav Šuštaršič, who continued his contrastive research of English and Slovene in contact within these projects. Several open issues of the Slovene standard language were also at the centre of his research interests, including the issue of tonemic accent in Slovene, which he studied mainly in collaboration with H. Tivadar. The findings of their works underlined a gap between the explicit norm and language use, which future codifiers of the Slovene standard language should take into consideration.

  9. The renewables portfolio standard in Texas: An early assessment

    Wiser, Ryan H.; Langniss, Ole

    2001-11-01

    Texas has rapidly emerged as one of the leading wind power markets in the United States. This development can be largely traced to a well-designed and carefully implemented renewables portfolio standard (RPS). The RPS is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation. Though replacing existing renewable energy policies with an as-of-yet largely untested approach in the RPS is risky, early experience from Texas suggests that an RPS can effectively spur renewables development and encourage competition among renewable energy producers. Initial RPS targets in Texas will be far exceeded by the end of 2001, with as much as 930 MW of wind slated for installation this year. RPS compliance costs appear negligible, with new wind projects reportedly contracted for under 3(US)/242/kWh, in part as a result of a 1.7(US)/242/kWh production tax credit, an outstanding wind resource, and an RPS that is sizable enough to drive project economies of scale. Obliged retail suppliers have been willing to enter into long-term contracts with renewable generators, reducing important risks for both the developer and the retail supplier. Finally, the country's first comprehensive renewable energy certificate program has been put into place to monitor and track RPS compliance.

    Magee, Justin; McClelland, Brian; Winder, John

    2012-09-01

    Digital modeling of human anatomy has become increasingly important and relies on well-documented quantitative anatomy literature. This type of documentation is common for the spine and pelvis; however, significant issues exist due to the lack of standardization in measurement and technique. Existing literature on quantitative anatomy for the spine and pelvis of white adults (aged 18-65 years, separated into decadal categories) was reviewed from the disciplines of anatomy, manipulative therapy, anthropometrics, occupational ergonomics, biomechanics and forensic science. The data were unified into a single normative model of the sub-axial spine. Two-dimensional orthographic drawings were produced from the 590 individual measurements identified, which informed the development of a 3D digital model. A similar review of full range of motion data was conducted as a meta-analysis and the results were applied to the existing model, providing an inter-connected, articulated digital spine. During these data analysis processes several inconsistencies were observed accompanied by an evidential lack of standardization with measurement and recording of data. These have been categorized as: anatomical terminology; scaling of measurements; measurement methodology, dimension and anatomical reference positions; global coordinate systems. There is inconsistency in anatomical terminology where independent researchers use the same terms to describe different aspects of anatomy or different terms for the same anatomy. Published standards exist for measurement methods of the human body regarding spatial interaction, anthropometric databases, automotive applications, clothing industries and for computer manikins, but none exists for skeletal anatomy. Presentation of measurements often lacks formal structure in clinical publications, seldom providing geometric reference points, therefore making digital reconstruction difficult. Published quantitative data does not follow existing

    2016-04-01

    In order to further advance research and development on the Clinical Data Interchange Standards Consortium (CDISC) Operational Data Model (ODM) standard, the existing research must be well understood. This paper presents a methodological review of the ODM literature. Specifically, it develops a classification schema to categorize the ODM literature according to how the standard has been applied within the clinical research data lifecycle. This paper suggests areas for future research and development that address ODM's limitations and capitalize on its strengths to support new trends in clinical research informatics. A systematic scan of the following databases was performed: (1) ABI/Inform, (2) ACM Digital, (3) AIS eLibrary, (4) Europe Central PubMed, (5) Google Scholar, (5) IEEE Xplore, (7) PubMed, and (8) ScienceDirect. A Web of Science citation analysis was also performed. The search term used on all databases was "CDISC ODM." The two primary inclusion criteria were: (1) the research must examine the use of ODM as an information system solution component, or (2) the research must critically evaluate ODM against a stated solution usage scenario. Out of 2686 articles identified, 266 were included in a title level review, resulting in 183 articles. An abstract review followed, resulting in 121 remaining articles; and after a full text scan 69 articles met the inclusion criteria. As the demand for interoperability has increased, ODM has shown remarkable flexibility and has been extended to cover a broad range of data and metadata requirements that reach well beyond ODM's original use cases. This flexibility has yielded research literature that covers a diverse array of topic areas. A classification schema reflecting the use of ODM within the clinical research data lifecycle was created to provide a categorized and consolidated view of the ODM literature. The elements of the framework include: (1) EDC (Electronic Data Capture) and EHR (Electronic Health Record

    Autotrophic microalgae represent a potential feedstock for transportation fuels, but life cycle assessment (LCA) studies based on laboratory-scale or theoretical data have shown mixed results. We attempt to bridge the gap between laboratory-scale and larger scale biodiesel production by using cultivation and harvesting data from a commercial algae producer with ∼1000 m(2) production area (the base case), and compare that with a hypothetical scaled up facility of 101,000 m(2) (the future case). Extraction and separation data are from Solution Recovery Services, Inc. Conversion and combustion data are from the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation Model (GREET). The LCA boundaries are defined as "pond-to-wheels". Environmental impacts are quantified as NER (energy in/energy out), global warming potential, photochemical oxidation potential, water depletion, particulate matter, and total NOx and SOx. The functional unit is 1 MJ of energy produced in a passenger car. Results for the base case and the future case show an NER of 33.4 and 1.37, respectively and GWP of 2.9 and 0.18 kg CO2-equivalent, respectively. In comparison, petroleum diesel and soy diesel show an NER of 0.18 and 0.80, respectively and GWP of 0.12 and 0.025, respectively. A critical feature in this work is the low algal productivity (3 g/m(2)/day) reported by the commercial producer, relative to the much higher productivities (20-30 g/m(2)/day) reported by other sources. Notable results include a sensitivity analysis showing that algae with an oil yield of 0.75 kg oil/kg dry biomass in the future case can bring the NER down to 0.64, more comparable with petroleum diesel and soy biodiesel. An important assumption in this work is that all processes are fully co-located and that no transport of intermediate or final products from processing stage to stage is required.

    Nuclear cardiology imaging tests are widely performed in Japan as clinical practice. The Japanese nuclear cardiology community has developed new diagnostic imaging tests using (123)I-beta-methyl-p-iodophenyl-pentadecanoic acid, (123)I-metaiodobenzylguanidine, and (18)F-fluorodeoxyglucose PET for detecting cardiac involvement in sarcoidosis. These tests have become popular worldwide. The Japanese Circulation Society and the Japanese Society of Nuclear Cardiology have published clinical imaging guidelines showing indications and standards for the new imaging tests. JSNC is currently striving to improve the standard of clinical practice and is promoting research activities.

    Full Text Available Introduction: A short screening tool for high-risk individuals with personality disorder (PD is useful both for clinicians and researchers. The aim of this study was to assess the validity and reliability of the Farsi version of the Standardized Assessment of Personality-Abbreviated Scale (SAPAS. Methods: The original English version of the SAPAS questionnaire was translated into Farsi, and then, translated back into English by two professionals. A survey was then conducted using the questionnaire on 150 clients of primary health care centers in Tabriz, Iran. A total of 235 medical students were also studied for the reliability assessment of the questionnaire. The SAPAS was compared to the short form of Minnesota Multiphasic Personality Inventory (MMPI. The data analysis was performed using receiver operating characteristic (ROC curve technique, operating characteristic for diagnostic efficacy, Cronbach's alpha, and test-retest for reliability evaluation. Results: We found an area under the curve (AUC of 0.566 [95% confidence intervals (CI: 0.455-0.677]; sensitivity of 0.89 and specificity of 0.26 at the cut-off score of 2 and higher. The total Cronbach's alpha coefficient was 0.38 and Cohen's kappa ranged between 0.5 and 0.8. Conclusion: The current study showed that the Farsi version of the SAPAS was relatively less efficient, in term of validity and reliability, in the screening of PD in the population.

    Postoperative infectious complications are independently associated with increased hospital length of stay (LOS) and cost and contribute to significant inpatient morbidity. Many strategies such as avoidance of long periods of preoperative fasting, re-establishment of oral feeding as early as possible after surgery, metabolic control and early mobilization have been used to either prevent or reduce the incidence of postoperative infections. Despite these efforts, it remains a big challenge to our current healthcare system to mitigate the cost of postoperative morbidity. Furthermore, preoperative nutritional status has also been implicated as an independent risk factor for postoperative morbidity. Perioperative nutritional support using enteral and parenteral routes has been shown to decrease postoperative morbidity, especially in high-risk patients. Recently, the role of immunonutrition (IMN) in postoperative infectious complications has been studied extensively. These substrates have been found to positively modulate postsurgical immunosuppression and inflammatory responses. They have also been shown to be cost-effective by decreasing both tpostoperative infectious complications and hospital LOS. In this review, we discuss the postoperative positive outcomes associated with the use of perioperative IMN, their cost-effectiveness, current guidelines and future clinical implications. © The Author(s) 2016.

    A nursing quality consortium standardized nursing practice across 17 independently functioning ambulatory oncology sites. Programs were developed to validate both competences and competencies. One program assessed nine competences needed to develop systems of care to detect and treat treatment-related side effects. A second program was developed to assess competencies needed to prevent harm to oncology patients. This manuscript describes a successful approach to standardizing nursing practice across geographically distant academic and community sites.

Motion sensors, pressure sensors, and tool-tip interaction software are a few of the broad categories of approaches that have been used in simulation-based assessments. The purpose of this article is to present a focused review of 3 sensor-enabled simulations that are currently being used for patient-centered assessments of clinical palpation skills. The first part of this article provides a review of technology components, capabilities, and metrics. The second part provides a detailed discussion regarding validity evidence and implications using the Standards for Educational and Psychological Testing as an organizational and evaluative framework. Special considerations are given to content domain and creation of clinical scenarios from a developer's perspective. The broader relationship of this work to the science of touch is also considered.

    Setting, maintaining and re-evaluation of assessment standard periodically are important issues in medical education. The cut-off scores are often "pulled from the air" or set to an arbitrary percentage. A large number of methods/procedures used to set standard or cut score are described in literature. There is a high degree of uncertainty in performance standard set by using these methods. Standards set using the existing methods reflect the subjective judgment of the standard setters. This review is not to describe the existing standard setting methods/procedures but to narrate the validity, reliability, feasibility and legal issues relating to standard setting. This review is on some of the issues in standard setting based on the published articles of educational assessment researchers. Standard or cut-off score should be to determine whether the examinee attained the requirement to be certified competent. There is no perfect method to determine cut score on a test and none is agreed upon as the best method. Setting standard is not an exact science. Legitimacy of the standard is supported when performance standard is linked to the requirement of practice. Test-curriculum alignment and content validity are important for most educational test validity arguments. Representative percentage of must-know learning objectives in the curriculum may be the basis of test items and pass/fail marks. Practice analysis may help in identifying the must-know areas of curriculum. Cut score set by this procedure may give the credibility, validity, defensibility and comparability of the standard. Constructing the test items by subject experts and vetted by multi-disciplinary faculty members may ensure the reliability of the test as well as the standard.

  9. Testing keywords internationally to define and apply undergraduate assessment standards in art and design

    2015-07-01

    Full Text Available What language should be featured in assessment standards for international students? Have universities adjusted their assessment methods sufficiently to match the increased demand for studying abroad? How might art and design benefit from a more stable definition of standards? These are some questions this paper seeks to address by reporting the results of recent pedagogic research at the School of the Arts, Loughborough University, in the United Kingdom. Language use is at the heart of this issue, yet it is generally overlooked as an essential tool that links assessment, feedback and action planning for international students. The paper reveals existing and new data that builds on research since 2009, aimed at improving students’ assessment literacy. Recommendations are offered to stimulate local and global discussion about keyword use for defining undergraduate assessment standards in art and design.

    Full Text Available EDITORIAL COMMENT The prevalence of urinary stone disease is increasing worldwide. The dissemination of the clinical use of the ultrasound has increased the rate of diagnosis of stones at an earlier stage, thus, has increased the expansion of the indications for flexible ureterorenoscopy (fURS. With the advancements in flexible ureteroscopy (FU, more successful outcomes are being reported. The most recent EAU guidelines state that fURS can be the first choice of treatment for all stones smaller than 2 cm. Especially for the lower pole stones, the stone-free rate is better than that with extracorporeal shock wave lithotripsy. For stones larger than 2 cm, staged procedures may be necessary. This paper recommends a standardized technique for fURS which is aimed to decrease the rate of possible complications and increase the success rate. Endourological techniques are widely adopted by most of the urological surgeons, hence fURS is an expansion of our surgical armamentarium. In this paper, an experienced group recommended some tips and tricks for each step of the procedure. The authors recommended general anesthesia over spinal anesthesia for two reasons: larger tidal volume during spinal anesthesia may cause movement, which can make the procedure harder. Secondly, the duration of the spinal anesthesia may be too short for some cases. Placement of ureteral access sheath (UAS should be done under fluoroscopic guidance and proper force should be applied. Ideally, the distal tip of the UAS should be just below the ureteropelvic junction. For preventing functional deterioration of the FU, the tip of the laser probe should be out of the scope as far as one-quarter of the screen diameter. For preventing excessive prolonged deflections, the stones in the lower pole should be repositioned in order to allow a more straight working channel. Pulverization of the stone is preferred over fragmentation since it decreases the operative time and risk of injury

    Background Myofascial pain syndrome (MPS) in the shoulder is among the most prevalent pain problems in the middle-aged population worldwide. Evidence suggests that peripheral and central sensitization may play an important role in the development and maintenance of shoulder MPS. Given previous research supporting the potential efficacy of anodal transcranial direct current stimulation (tDCS) for modulating pain-related brain activity in individuals with refractory central pain, we hypothesized that anodal tDCS when applied over the primary motor cortex (M1) combined with standard treatment will be more effective for reducing pain in patients with MPS than standard treatment alone. Method Study participants were randomized to receive either (1) standard treatment with 5-consecutive days of 1 mA anodal tDCS over M1 for 20 min or (2) standard treatment plus sham tDCS. Measures of pain intensity, shoulder passive range of motion, analgesic medication use, and self-reported physical functioning were administered before treatment and again at post-treatment and 1-, 2-, 3-and 4-week follow-up. Results Thirty-one patients with MPS were enrolled. Participants assigned to the active tDCS condition reported significantly more pre- to post-treatment reductions in pain intensity that were maintained at 1-week post-treatment, and significant improvement in shoulder adduction PROM at 1-week follow-up than participants assigned to the sham tDCS condition. Conclusion 5 consecutive days of anodal tDCS over M1 combined with standard treatment appears to reduce pain intensity, and may improve PROM, faster than standard treatment alone. Further tests of the efficacy and duration of effects of tDCS in the treatment of MPS are warranted. PMID:25373724

  13. Assessing risk of non-compliance of phosphorus standards for lakes in England and Wales

    2009-04-01

    High population densities, use of inorganic fertilizer and intensive livestock agriculture have increased phosphorus loads to lakes, and accelerated eutrophication is a major pressure for many lakes. The EC Water Framework Directive (WFD) requires that good chemical and ecological quality is restored in all surface water bodies by 2015. Total phosphorus (TP) standards for lakes in England and Wales have been agreed recently, and our aim was to estimate what percentage of lakes in England and Wales is at risk of failing these standards. With measured lake phosphorus concentrations only being available for a small number of lakes, such an assessment had to be model based. The study also makes a source apportionment of phosphorus inputs into lakes. Phosphorus loads were estimated from a range of sources including agricultural loads, sewage effluents, septic tanks, diffuse urban sources, atmospheric deposition, groundwater and bank erosion. Lake phosphorus concentrations were predicted using the Vollenweider model, and the model framework was satisfactorily tested against available observed lake concentration data. Even though predictions for individual lakes remain uncertain, results for a population of lakes are considered as sufficiently robust. A scenario analysis was carried out to investigate to what extent reductions in phosphorus loads would increase the number of lakes achieving good ecological status in terms of TP standards. Applying the model to all lakes in England and Wales greater than 1 ha, it was calculated that under current conditions roughly two thirds of the lakes would fail the good ecological status with respect to phosphorus. According to our estimates, agricultural phosphorus loads represent the most frequent dominant source for the majority of catchments, but diffuse urban runoff also is important in many lakes. Sewage effluents are the most frequent dominant source for large lake catchments greater than 100 km². The evaluation in terms of

  2. Emission standards versus immission standards for assessing the impact of urban drainage on ephemeral receiving water bodies.

    Freni, Gabriele; Mannina, Giorgio; Viviani, Gaspare

    2010-01-01

    In the past, emission standard indicators have been adopted by environmental regulation authorities in order to preserve the quality of a receiving water body. Such indicators are based on the frequency or magnitude of a polluted discharge that may be continuous or intermittent. In order to properly maintain the quality of receiving waters, the Water Framework Directive, following the basic ideas of British Urban Pollution Manual, has been established. The Directive has overtaken the emission-standard concept, substituting it with the stream-standard concept that fixes discharge limits for each polluting substance depending on the self-depurative characteristics of receiving waters. Stream-standard assessment requires the deployment of measurement campaigns that can be very expensive; furthermore, the measurement campaigns are usually not able to provide a link between the receiving water quality and the polluting sources. Therefore, it would be very useful to find a correlation between the quality status of the natural waters and the emission-based indicators. Thus, this study is aimed to finding a possible connection between the receiving water quality indicators drawn by environmental regulation authorities and emission-based indicators while considering both continuous (i.e. from the wastewater treatment plants) and intermittent pollution discharges (mainly from combined sewer overflows). Such research has been carried out by means of long-term analysis adopting a holistic modelling approach. The different parts of the integrated urban drainage system were modelled by a parsimonious integrated model. The analysis was applied to an ephemeral river bounding Bologna (Italy). The study concluded that the correlation between receiving water quality and polluting emissions cannot be generally stated. Nevertheless, specific analyses on polluting emissions were pointed out in the study highlighting cause-effect link between polluting sources and receiving water quality.

    Insulin resistance contributes to the pathophysiology of diabetes and is a hallmark of obesity, metabolic syndrome, and many cardiovascular diseases. Therefore, quantifying insulin sensitivity/resistance in humans and animal models is of great importance for epidemiological studies, clinical and basic science investigations, and eventual use in clinical practice. Direct and indirect methods of varying complexity are currently employed for these purposes. Some methods rely on steady-state analysis of glucose and insulin, whereas others rely on dynamic testing. Each of these methods has distinct advantages and limitations. Thus, optimal choice and employment of a specific method depends on the nature of the studies being performed. Established direct methods for measuring insulin sensitivity in vivo are relatively complex. The hyperinsulinemic euglycemic glucose clamp and the insulin suppression test directly assess insulin-mediated glucose utilization under steady-state conditions that are both labor and time intensive. A slightly less complex indirect method relies on minimal model analysis of a frequently sampled intravenous glucose tolerance test. Finally, simple surrogate indexes for insulin sensitivity/resistance are available (e.g., QUICKI, HOMA, 1/insulin, Matusda index) that are derived from blood insulin and glucose concentrations under fasting conditions (steady state) or after an oral glucose load (dynamic). In particular, the quantitative insulin sensitivity check index (QUICKI) has been validated extensively against the reference standard glucose clamp method. QUICKI is a simple, robust, accurate, reproducible method that appropriately predicts changes in insulin sensitivity after therapeutic interventions as well as the onset of diabetes. In this Frontiers article, we highlight merits, limitations, and appropriate use of current in vivo measures of insulin sensitivity/resistance.

    To develop and propose a standardized battery of neuropsychological tests for the assessment of cognitive functioning of children and adolescents with pediatric systemic lupus erythematosus (SLE). A committee of health care professionals involved in the assessment of pediatric SLE patients reviewed the literature to identify cognitive domains most commonly affected in pediatric SLE and in adult SLE. They then reviewed the standardized tests available for children and adolescents that assess the cognitive domains identified. Through a structured consensus formation process, the committee considered the psychometric characteristics and durations of the tests. A test battery was developed that appears suitable to provide a comprehensive assessment of cognitive domains commonly affected by pediatric SLE within a 2.5-hour period. It is hoped that the consistent use of this reliable and efficient battery increases the practicality of routine evaluations in pediatric SLE, enabling between-cohort comparisons and facilitating the longitudinal assessment of individual patients over time.

    Autistic individuals often struggle developmentally, even in areas that are not explicit diagnostic criteria, such as motor skills. This study explored the relation between early motor skills, assessed retrospectively, and current pragmatic language skills. Caregivers of neurotypical and autistic children, matched on gender and age, completed assessments of their child's early motor development and current language abilities. Early motor skills were correlated with later pragmatic language skills, and autistic children exhibited fewer motor skills than neurotypical children. In fact, motor skills were a better predictor of an autism spectrum diagnosis than were scores on a measure of current pragmatic language. These results highlight the important role of motor skills in autism spectrum disorders.

    Otolaryngologists utilize a variety of diagnostic techniques to assess middle ear health. Tympanometry, audiometry, and otoacoustic emissions examine the mobility of the tympanic membrane (eardrum) and ossicles using ear canal pressure and auditory tone delivery and detection. Laser Doppler vibrometry provides non-contact vibrational measurement, and acoustic reflectometry is used to assess middle ear effusion using sonar. These technologies and techniques have advanced the field beyond the use of the standard otoscope, a simple tissue magnifier, yet the need for direct visualization of middle ear disease for superior detection, assessment, and management remains. In this study, we evaluated the use of portable optical coherence tomography (OCT) and pneumatic low-coherence interferometry (LCI) systems with handheld probe delivery to standard tympanometry, audiometry, otoacoustic emissions, laser Doppler vibrometry, and acoustic reflectometry. Comparison of these advanced optical imaging techniques and current diagnostics was conducted with a case study subject with a history of unilateral eardrum trauma. OCT and pneumatic LCI provide novel dynamic spatiotemporal structural data of the middle ear, such as the thickness of the eardrum and quantitative detection of underlying disease pathology, which could allow for more accurate diagnosis and more appropriate management than currently possible.

  15. Assessing the Impact of Stricter Alcohol Advertising Standards: The Case of Beam Global Spirits

    Ross, Craig S.; Sparks, Alicia; Jernigan, David H.

    2015-01-01

    Summary Reducing youth exposure to alcohol advertising is a global health priority. In most countries around the world, the alcohol industry is given the opportunity to regulate itself with respect to advertising practices. Generally, the alcohol industry self-regulations are lax, allowing youth to be disproportionately exposed to alcohol advertising. However, Beam Global Spirits and Wine (Beam) voluntarily adopted more restrictive advertising standards in the United States in 2007. This study assessed Beam's compliance with their new standard and estimates its effect on youth exposure and advertising costs. We found that Beam's compliance with its more restrictive standards was imperfect, but never-the-less, we estimated that youth exposure to alcohol advertising was reduced compared to other spirits brands. Beam's more restrictive standards did not increase their advertising costs and therefore other alcohol companies should consider adopting similar standards around the world. PMID:28042284

  16. Assessing Quality of Data Standards: Framework and Illustration Using XBRL GAAP Taxonomy

    Zhu, Hongwei; Wu, Harris

    The primary purpose of data standards or metadata schemas is to improve the interoperability of data created by multiple standard users. Given the high cost of developing data standards, it is desirable to assess the quality of data standards. We develop a set of metrics and a framework for assessing data standard quality. The metrics include completeness and relevancy. Standard quality can also be indirectly measured by assessing interoperability of data instances. We evaluate the framework using data from the financial sector: the XBRL (eXtensible Business Reporting Language) GAAP (Generally Accepted Accounting Principles) taxonomy and US Securities and Exchange Commission (SEC) filings produced using the taxonomy by approximately 500 companies. The results show that the framework is useful and effective. Our analysis also reveals quality issues of the GAAP taxonomy and provides useful feedback to taxonomy users. The SEC has mandated that all publicly listed companies must submit their filings using XBRL. Our findings are timely and have practical implications that will ultimately help improve the quality of financial data.

    The objective of the present paper was to review international and national standards for the criteria of assessment of the noise-induced occupational loss of hearing. The importance of healthy hearing for the occupational safety is emphasized which implies the necessity of the more rigorous criteria for hearing conservation in the workers engaged in the noisy technological environment compared with those for the general population. A rationale for the development of the standard program of hearing conservation in the workers engaged in the noisy technological environment is proposed including hygienic norms and rules or national state standards.

    Neuropsychiatric symptoms, such as apathy, have an important impact on the quality of life of both patients diagnosed with dementia and their caregivers and represent a strong predictor of progression of the illness. Current clinical assessment methods risk bias resulting from the assessor's subjectivity, pointing to a need for additional objective and systematic assessment tools. Therefore, the use of information and communication technologies (ICT) such as actigraphy and automatized video monitoring are of interest in addition to current assessment methods. The goal of this study is to give an overview of current assessment tools for apathy in clinical practice and new approaches to assessment methods with the help ICT. This study was conducted with the use of narrative literature overview. There is evidence that apart from the currently used assessment methods for apathy, new ICT approaches could provide clinicians with valuable additional information for an earlier detection and therefore more accurate diagnosis of apathy. There are no ICT techniques specifically designed for the assessment of apathy, but nevertheless several techniques seem to be promising and deserve more study.

    The aim of this study was to gain insight into the nature of the role played by self- and peer assessment in the development of dental students' reflective practice skills and the value gained through structured encounters with standardized patients. Four standardized patient encounters in an objective structured clinical exam (OSCE) format served as a learning experience for students to demonstrate decision making and communication skills in complex scenarios regarding issues of ethics. Self- and peer assessment and peer-to-peer discourse were used to enhance student reflection. A sample of 16 peer pairs was randomly selected from the population of 108 fourth-year students who participated in the 2014 Clinical Dental Ethics OSCE. Data were collected from self- and peer assessment forms. Five overall performance themes (personal affect, verbal communication, professional demeanor, relationship-building, and patient management) and three student learning themes (application and knowledge, ways to change, and impressed with peer/increased confidence in self) were identified. The results showed that peer assessment ratings were consistently higher than those in the self-assessments, but overall the students deemed both their peers' and their own decision making and communication skills to be quite good. These students rated their experience with the OSCE and self- and peer assessments as positive, appreciating the importance of reflection and learning from their peers. These results provide support for the continued formative use of standardized patient OSCEs and self- and peer assessment to help students develop skills in decision making, communication, professionalism, and reflection.

    2010-01-01

    The Italian decree law 81/2008 mentions the application of ergonomic principles as a basic tool for the prevention. In this regulation we can not find the definition either of Ergonomics nor of the competences required for its correct application. The Authors consider that occupational physicians have a suitable competence and knowledge on the matter, thanks to their highly specialized training. Actually, the ergonomic doctrine shows up in the daily practice of occupational physicians, who regularly base their activity on the evaluation of the binomial "worker-task": in the management of fitness to work judgements they try to combine operating conditions with worker's psychophysical state, not confining themselves to a simple expression ofa medico-legal certificate. However, the legislative references to specific regulations raise difficulties to occupational physicians in dealing with aspects such as gender, age, reference values and methodological choices. The Authors debate these difficulties in the application of rules.

    This article outlines several important issues regarding the management of patients with gout. The topics discussed include best practices for gout based on the most current guidelines, opportunities for improving gout management, and current and emerging therapies for gout. [PubMed and Google Scholar databases] were search for all articles and trials published before 2016, using the key terms [hyperuricemia, gout, tophi, joint erosion, joint damage, treatment guidelines, American College of Rheumatology (ACR), European League Against Rheumatism (EULAR), flare, comorbidity, epidemiology, adherence, serum uric acid (sUA), monosodium urate (MSU), gout treatment, including drugs under development, and on the management of gout from both the physician and patient perspectives. The reference lists of identified articles were searched manually for additional publications. Gout, a progressive debilitating form of inflammatory arthritis, is caused by factors that elevate serum uric acid (sUA) levels, leading to hyperuricemia. Continued elevated sUA can result in monosodium urate crystal deposition in joints and soft tissues, causing acute and chronic inflammation. Crystal deposition can lead to chronic gout, with an increased number of flares, tophi development, and structural joint damage. The aims of gout treatment are to reduce the sUA level to Gout is often poorly managed for several reasons, including a lack of adherence to treatment guidelines by health care providers, patients' poor adherence to therapy, and differences between a provider's and patient's perspectives regarding treatment. Patients need to be educated about their diagnosis and management of the disease, such as the importance of compliance with long-term treatment. Gout treatment may also confounded by contraindications to current standards of therapy and the limitations of current treatment paradigms. Recently approved medications, as well as drugs under development, may provide new ways for reaching

  3. Toward Clarity in Clinical Vitamin D Status Assessment: 25(OH)D Assay Standardization.

    2017-12-01

    Widespread variation in 25-hydroxyvitamin D (25(OH)D) assays continues to compromise efforts to develop clinical and public health guidelines regarding vitamin D status. The Vitamin D Standardization Program helps alleviate this problem. Reference measurement procedures and standard reference materials have been developed to allow current, prospective, and retrospective standardization of 25(OH)D results. Despite advances in 25(OH)D measurement, substantial variability in clinical laboratory 25(OH)D measurement persists. Existing guidelines have not used standardized data and, as a result, it seems unlikely that consensus regarding definitions of vitamin D deficiency, inadequacy, sufficiency, and excess will soon be reached. Until evidence-based consensus is reached, a reasonable clinical approach is advocated. Copyright © 2017 Elsevier Inc. All rights reserved.

    Construct: This study aims to provide validity evidence for the standardized Assessment Letter for Pediatrics as a measure of competencies expected of a 1st-year pediatrics resident as part of a pediatric residency admissions process. The Narrative Letter of Recommendation is a frequently used tool in the residency admissions process even though it has poor interrater reliability, lacks pertinent content, and does not correlate with residency performance. A newer tool, the Standardized Letter, has shown validity evidence for content and interrater reliability in other specialties. We sought to develop and provide validity evidence for the standardized Assessment Letter for Pediatrics. All 2012 and 2013 applicants invited to interview at the University of Geneva Pediatrics Residency Program provided 2 standardized Assessment Letters. Content for the letter was based on CanMEDS roles and ratings of 6 desired competencies and an overall assessment. Validity evidence was gathered for internal structure (Cronbach's alpha and generalizability), response process (interrater reliability with intraclass correlation), relations to other variables (Pearson's correlation coefficient), and consequences (logistic regression to predict admission). One hundred fourteen faculty completed 142 standardized Assessment Letters for 71 applicants. Average overall assessment was 3.0 of 4 (SD = 0.59). Cronbach's alpha was 0.93. The G-coefficient was 0.59. The decision study projected that four Assessment Letters are needed to attain a G-coefficient of 0.73. Applicant variance (28.5%) indicated high applicant differentiation. The Assessment Letter intraclass coefficient was 0.51, 95% confidence interval (CI) [0.43, 0.59]. Assessment Letter scores were correlated with the structured interview (r = .28), 95% CI [0.05, 0.51]; global rating (r = .36), 95% CI [0.13, 0.58]; and admissions decision (r = .25), 95% CI [0.02, 0.46]. Assessment Letter scores did not predict the admissions decision

  5. Reconsidering the risk assessment concept: Standardizing the impact description as a building block for vulnerability assessment

    Full Text Available Risk assessments for natural hazards are becoming more widely used and accepted. Using an extended definition of risk, it becomes obvious that performant procedures for vulnerability assessments are vital for the success of the risk concept. However, there are large gaps in knowledge about vulnerability. To alleviate the situation, a conceptual extension of the scope of existing and new models is suggested. The basis of the suggested concept is a stadardization of the output of hazard assessments. This is achieved by defining states of the target objects that depend on the impact and at the same time affect the object's performance characteristics. The possible state variables can be related to a limited set of impact descriptors termed generic impact description interface. The concept suggests that both hazard and vulnerability assessment models are developed according to the specification of this interface, thus facilitating modularized risk assessments. Potential problems related to the application of the concept include acceptance issues and the lacking accuracy of transformation of outputs of existing models. Potential applications and simple examples for adapting existing models are briefly discussed.

    Full Text Available Objective: Diabetes has gradually emerged as one of the most serious public health problems in our country. This underlines the need for timely disease detection and decisive therapeutic intervention. This prospective cross-sectional observational study aims at analyzing the utilization pattern of antidiabetic agents in a remote North-East Indian tertiary care teaching hospital in the perspective of current standard treatment guidelines. Materials and Methods: Diabetic patients receiving antidiabetic medication, both as outpatients and inpatients in our hospital over a period of 12 months (May 2013–May 2014, were included in this study. The data obtained were sorted and analyzed on the basis of gender, type of therapy, and hospital setting. Results: A total of 310 patients were included in the study. Metformin was the single most frequently prescribed antidiabetic agent (66.8% followed by the sulfonylureas group (37.4%. Insulin was prescribed in 23.2% of the patients. Combination antidiabetic drug therapy (65.1% was used more frequently than monotherapy (34.8%. The use of biguanides (P < 0.0001 and sulfonylureas (P = 0.02 in combination was significant as compared to their use as monotherapy. A total of 48% of all antidiabetic combinations used, comprised metformin and sulfonylureas (n = 96. Insulin use was significantly higher as monotherapy and in inpatients (P< 0.0001. The utilization of drugs from the National List of Essential Medicines was 51.2%, while 11% of antidiabetics were prescribed by generic name. Conclusion: The pattern of utilization largely conforms to the current standard treatment guidelines. Increased use of generic drugs is an area with scope for improvement.

    An assessment of a draft AIAA standard for flight dynamics model exchange, ANSI/AIAA S-119-2011, was conducted on behalf of NASA by a team from the NASA Engineering and Safety Center. The assessment included adding the capability of importing standard models into real-time simulation facilities at several NASA Centers as well as into analysis simulation tools. All participants were successful at importing two example models into their respective simulation frameworks by using existing software libraries or by writing new import tools. Deficiencies in the libraries and format documentation were identified and fixed; suggestions for improvements to the standard were provided to the AIAA. An innovative tool to generate C code directly from such a model was developed. Performance of the software libraries compared favorably with compiled code. As a result of this assessment, several NASA Centers can now import standard models directly into their simulations. NASA is considering adopting the now-published S-119 standard as an internal recommended practice.

    This study was conducted to establish a prognostic model in patients with pathologic N1 (pN1) breast cancer who have not undergone elective nodal irradiation (ENI) under the current standard management and to suggest possible indications for ENI. We performed a retrospective study with patients with pN1 breast cancer who received the standard local and preferred adjuvant chemotherapy treatment without neoadjuvant chemotherapy and ENI from January 2005 to June 2011. Most of the indicated patients received endocrine and trastuzumab therapy. In 735 enrolled patients, the median follow-up period was 58.4 months (range, 7.2-111.3 months). Overall, 55 recurrences (7.4%) developed, and locoregional recurrence was present in 27 patients (3.8%). Recurrence-free survival was significantly related to lymphovascular invasion (P = .04, hazard ratio [HR], 1.83; 95% confidence interval [CI], 1.03-2.88), histologic grade (P = .03, HR, 2.57; 95% CI, 1.05-6.26), and nonluminal A subtype (P = .02, HR, 3.04; 95% CI, 1.23-7.49) in multivariate analysis. The prognostic model was established by these 3 prognostic factors. Recurrence-free survival was less than 90% at 5 years in cases with 2 or 3 factors. The prognostic model has stratified risk groups in pN1 breast cancer without ENI. Patients with 2 or more factors should be considered for ENI. Copyright © 2015 Elsevier Inc. All rights reserved.

    Number-processing may be altered following brain injury and might affect the everyday life of patients. We developed the first ecological tool to assess number-processing disorders in brain-injured patients, the Ecological Assessment Battery for Numbers (EABN; in French, the BENQ). The aim of the present study was to standardize and validate this new tool. Standardization included 126 healthy controls equally distributed by age, sex and sociocultural level. First, 17 patients were evaluated by the EABN; then scores for a subgroup of 10 were compared with those from a French analytical calculation test, the Évaluation Clinique des Aptitudes Numériques (ECAN). The concordance between the EABN and the ECAN was analyzed to determine construct validity. Discrimination indexes were calculated to assess the sensitivity of the subtests. Standardization highlighted a major effect of sociocultural level. In total, 9 of 17 patients had a pathological EABN score, with difficulties in telling time, making appointments and reading numerical data. The results of both the EABN and ECAN tests were concordant (Kendall's w=0.97). Finally, the discriminatory power was good, particularly for going to the movies, cheque-writing and following a recipe: scores were>0.4. The EABN is a new tool to assess number-processing disorders in adults. This tool has been standardized and has good psychometric properties for patients with brain injury.

    Full Text Available This study reports the results of a survey about the improvements achieved as result of ISO 14000 Environmental Management System (EMS standard implementation and the differences of improvements with respect to firm characteristics. A survey has been conducted in order to explain the improvements related to environmental management process and overall firm performance. The survey involved sixty-six enterprises implementing ISO 14000 EMS standard in Turkey. In order to assess improvements obtained from ISO 14000 EMS implementation, statements related to environmental management process and overall firm performance indicators have been prepared. The statements in this study are relevant to previous research. A factor analysis was employed to determine the factors of the variables explaining improvements. Nine factors have been identified related to achieved improvements, such as establishment of pro-active environmental management system, effectiveness in resource utilization, effectiveness of process control, relationships with industry and government, meeting expectations of stakeholders, demonstration of social responsibility, profitability, productivity, and competitiveness. Then, a T- test was conducted to determine the differences of managers’ assessments with respect to certain firm characteristics. The findings have shown that there are differences in the assessments of improvements achieved as a result of ISO 14000 EMS standard implementation with respect to sales volume, foreign-capital possession, and ISO 14000 EMS standard implementation. On the other hand, industrial sector, age of establishment, and export orientation are not statistically significant for the differences in the assessments of improvements.

    2015-04-01

    Sustainability standards and certification serve to differentiate and provide market recognition to goods produced in accordance with social and environmental good practices, typically including practices to protect biodiversity. Such standards have seen rapid growth, including in tropical agricultural commodities such as cocoa, coffee, palm oil, soybeans, and tea. Given the role of sustainability standards in influencing land use in hotspots of biodiversity, deforestation, and agricultural intensification, much could be gained from efforts to evaluate and increase the conservation payoff of these schemes. To this end, we devised a systematic approach for monitoring and evaluating the conservation impacts of agricultural sustainability standards and for using the resulting evidence to improve the effectiveness of such standards over time. The approach is oriented around a set of hypotheses and corresponding research questions about how sustainability standards are predicted to deliver conservation benefits. These questions are addressed through data from multiple sources, including basic common information from certification audits; field monitoring of environmental outcomes at a sample of certified sites; and rigorous impact assessment research based on experimental or quasi-experimental methods. Integration of these sources can generate time-series data that are comparable across sites and regions and provide detailed portraits of the effects of sustainability standards. To implement this approach, we propose new collaborations between the conservation research community and the sustainability standards community to develop common indicators and monitoring protocols, foster data sharing and synthesis, and link research and practice more effectively. As the role of sustainability standards in tropical land-use governance continues to evolve, robust evidence on the factors contributing to effectiveness can help to ensure that such standards are designed and

    BACKGROUND: This project directly and empirically measured the level of gastrointestinal (GI) illness related to the consumption of tapwater prepared from sewage-contaminated surface waters and meeting current water quality criteria. METHODS: A randomized intervention trial was carried out; 299 eligible households were supplied with domestic water filters (reverse-osmosis) that eliminate microbial and chemical contaminants from their water, and 307 households were left with their usual tapwater without a filter. The GI symptomatology was evaluated by means of a family health diary maintained prospectively by all study families over a 15-month period. RESULTS: The estimated annual incidence of GI illness was 0.76 among tapwater drinkers compared with 0.50 among filtered water drinkers (p less than 0.01). These findings were consistently observed in all population subgroups. CONCLUSION: It is estimated that 35% of the reported GI illnesses among the tapwater drinkers were water-related and preventable. Our results raise questions about the adequacy of current standards of drinking water quality to prevent water-borne endemic gastrointestinal illness. PMID:2029037

  11. Paralympic sports medicine--current evidence in winter sport: considerations in the development of equipment standards for paralympic athletes.

    Science.gov (United States)

    Burkett, Brendan

    2012-01-01

    To highlight and discuss the considerations for the future development of equipment standards for Winter Paralympic sports. Literature searches were performed (in English) during May 2011 using the key words "technology, winter sport, Olympic, and Paralympic" in the computerized databases PubMed, PsycINFO, Science Direct, and Google Scholar. In addition, personal scientific observations were made at several Winter Paralympic Games. The retrieved articles were screened and assessed for relevance to the biological, biomechanical, and sport medicine aspects of equipment. There are 3 key areas in which technology has influenced sports performance in Paralympic winter sports, namely, specialized prostheses, crutch skis or outriggers (in lieu of poles), and sport-specific wheelchairs (such as the sit-ski). From a sport medicine perspective, a crucial factor not considered in the standard laboratory test of mechanical efficiency is the influence of the human-equipment connection, such as the stump-to-prosthesis interface or the required human-to-wheelchair control. This connectivity is critical to the effective operation of the assistive device. When assessing the efficiency of this equipment, the not-so-obvious, holistic, compensatory factors need to be considered. Assistive equipment is fundamental for a person with a disability to participate and compete in winter sport activities. Although there have been improvements in the mechanical function of some assistive devices, the key issue is matching the residual function of the person with the assistive equipment. Equitable access to this technology will also ensure that the fundamental spirit of fair play that underpins the Paralympic Games is maintained.

    Johnsen, David C; Williams, John N; Baughman, Pauletta Gay; Roesch, Darren M; Feldman, Cecile A

    2015-10-01

    This opinion article applauds the recent introduction of a new dental accreditation standard addressing critical thinking and problem-solving, but expresses a need for additional means for dental schools to demonstrate they are meeting the new standard because articulated outcomes, learning models, and assessments of competence are still being developed. Validated, research-based learning models are needed to define reference points against which schools can design and assess the education they provide to their students. This article presents one possible learning model for this purpose and calls for national experts from within and outside dental education to develop models that will help schools define outcomes and assess performance in educating their students to become practitioners who are effective critical thinkers and problem-solvers.

    2016-08-01

    Introduction Disasters often overwhelm a community's capacity to respond and recover, creating a gap between the needs of the community and the resources available to provide services. In the wake of multiple disasters affecting nursing homes in the last decade, increased focus has shifted to this vital component of the health care system. However, the long-term care sector has often fallen through the cracks in both planning and response. Problem Two recent reports (2006 and 2012) published by the US Department of Health and Human Services (DHHS), Office of Inspector General (OIG), elucidate the need for improvements in nursing homes' comprehensive emergency preparedness and response. The Center for Medicare and Medicaid Services (CMS) has developed an emergency preparedness checklist as a guidance tool and proposed emergency preparedness regulations. The purpose of this study was to evaluate the progress made in nursing home preparedness by determining the level of completion of the 70 tasks noted on the checklist. The study objectives were to: (1) determine the preparedness levels of nursing homes in North and South Carolina (USA), and (2) compare these findings with the 2012 OIG's report on nursing home preparedness to identify current gaps. A survey developed from the checklist of items was emailed to 418 North Carolina and 193 South Carolina nursing home administrators during 2014. One hundred seventeen were returned/"bounced back" as not received. Follow-up emails and phone calls were made to encourage participation. Sixty-three completed surveys and 32 partial surveys were received. Responses were compared to data obtained in a 2010 study to determine progress. Progress had been made in many of the overall planning and sheltering-in-place tasks, such as having contact information of local emergency managers as well as specifications for availability of potable water. Yet, gaps still persisted, especially in evacuation standards, interfacing with emergency

    2007-11-01

    To evaluate methods of performance assessment through an international literature review and a survey of current practice. Over the past two decades health care organizations have focussed on promoting high quality care in conjunction with retaining motivated staff. Cognisant of such initiatives, we sought to evaluate assessment methods for qualified staff according to their utility in the working environment. A systematic literature search was completed and each paper independently reviewed. All health care organizations in Northern Ireland submitted details of their performance assessments. Each was critically appraised using a utility index. Performance was not universally defined. A broad range of assessments were identified, each method had advantages and disadvantages. Although many lacked rigorous testing, areas of good practice were also noted. No single method is appropriate for assessing clinical performance. Rather, this study endorses proposals for a multi-method strategy to ensure that performance assessment demonstrates all attributes required for effective nursing and midwifery practice.

  16. New Concept for Assessment of Tidal Current Energy in Jiangsu Coast, China

    2013-01-01

    Full Text Available Tidal current energy has attracted more and more attentions of coastal engineers in recent years, mainly due to its advantages of low environmental impact, long-term predictability, and large energy potential. In this study, a two-dimensional hydrodynamic model is applied to predict the distribution of mean density of tidal current energy and to determine a suitable site for energy exploitation in Jiangsu Coast. The simulation results including water elevation and tidal current (speed and direction were validated with measured data, showing a reasonable agreement. Then, the model was used to evaluate the distribution of mean density of tidal current energy during springtide and neap tide in Jiangsu Coast. Considering the discontinuous performance of tidal current turbine, a new concept for assessing tidal current energy is introduced with three parameters: total operating time, dispersion of operating time, and mean operating time of tidal current turbine. The operating efficiency of tidal current turbine at three locations around radial submarine sand ridges was taken as examples for comparison, determining suitable sites for development of tidal current farm.

  17. Improving pest risk assessment and management through the aid of geospatial information technology standards

    2013-09-01

    Full Text Available Delivery of geospatial information over the Internet for the management of risks from invasive alien species is an increasingly important service. The evolution of information technology standards for geospatial data is a key factor to simplify network publishing and exchange of maps and data. The World Wide Web Consortium (W3C-geolocation specification is a recent addition that may prove useful for pest risk management. In this article we implement the W3C-geolocation specification and Open Geospatial Consortium (OGC mapping standards in a Web browser application for smartphones and tablet computers to improve field surveys for alien invasive species. We report our first season field experiences using this tool for online mapping of plant disease outbreaks and host plant occurrence. It is expected that the improved field data collection tools will result in increased data availability and thereby new opportunities for risk assessment, because data-needs and availability are crucial for species distribution modelling and model-based forecasts of pest establishment potential. Finally, we close with a comment on the future potential of geospatial information standards to enhance the translation from data to decisions regarding pest risks, which should enable earlier detection of emerging risks as well as more robust projections of pest risks in novel areas. The forthcoming standard for processing of geospatial information, the Web Processing Standard (WPS, should open new technological capabilities both for automatic initiation and updating of risk assessment models based on new incoming data, and subsequent early warning.

  18. Considerations for Using Genetic and Epigenetic Information in Occupational Health Risk Assessment and Standard Setting.

    Science.gov (United States)

    Schulte, P A; Whittaker, C; Curran, C P

    2015-01-01

    Risk assessment forms the basis for both occupational health decision-making and the development of occupational exposure limits (OELs). Although genetic and epigenetic data have not been widely used in risk assessment and ultimately, standard setting, it is possible to envision such uses. A growing body of literature demonstrates that genetic and epigenetic factors condition biological responses to occupational and environmental hazards or serve as targets of them. This presentation addresses the considerations for using genetic and epigenetic information in risk assessments, provides guidance on using this information within the classic risk assessment paradigm, and describes a framework to organize thinking about such uses. The framework is a 4 × 4 matrix involving the risk assessment functions (hazard identification, dose-response modeling, exposure assessment, and risk characterization) on one axis and inherited and acquired genetic and epigenetic data on the other axis. The cells in the matrix identify how genetic and epigenetic data can be used for each risk assessment function. Generally, genetic and epigenetic data might be used as endpoints in hazard identification, as indicators of exposure, as effect modifiers in exposure assessment and dose-response modeling, as descriptors of mode of action, and to characterize toxicity pathways. Vast amounts of genetic and epigenetic data may be generated by high-throughput technologies. These data can be useful for assessing variability and reducing uncertainty in extrapolations, and they may serve as the foundation upon which identification of biological perturbations would lead to a new paradigm of toxicity pathway-based risk assessments.

  19. Towards continuous improvement of endoscopy standards: Validation of a colonoscopy assessment form.

    LENUS (Irish Health Repository)

    2012-02-01

    Aim: Assessment of procedural colonoscopy skills is an important and topical. The aim of this study was to develop and validate a competency-based colonoscopy assessment form that would be easy to use, suitable for the assessment of junior and senior endoscopists and potentially be a useful instrument to detect differences in performance standards following different training interventions. Method: A standardised assessment form was developed incorporating a checklist with dichotomous yes\\/no responses and a global assessment section incorporating several different elements. This form was used prospectively to evaluate colonoscopy cases during the period of the study in several university teaching hospitals. Results were analysed using ANOVA with Bonferroni corrections for post-hoc analysis. Results: 81 procedures were assessed, performed by eight consultant and 19 trainee endoscopists. There were no serious errors. When divided into three groups based on previous experience (novice, intermediate and expert) the assessment form demonstrated statistically significant differences between all three groups (p<0.05). When separate elements were taken into account, the global assessment section was a better discriminator of skill level than the checklist. Conclusion: This form is a valid, easy to use assessment method. We intend to use it to assess the value of simulator training in trainee endoscopists. It also has the potential to be a useful training tool when feedback is given to the trainee.

    To describe physical examination and cancer prevention services provided by primary care physicians in response to the request for a "checkup" by an asymptomatic 55-year-old woman seeking to establish ongoing care; to assess the effects of two interventions (education and office organization) intended to improve these services; and to assess the feasibility of using "standardized" patients to evaluate physician responses to such a request. Northern New England. Fifty-nine primary care physicians who were accepting new patients and were participating in a study of early detection and prevention of cancer. Cross sectional; observations of patient visits. Actresses trained to portray a specific patient role ("standardized" or "simulated" patients) visited each physician once. Physicians were blinded to the simulated patients' true identities. Actresses reported the components of the general physical examination and the cancer-related "checkup." Most interactions were audiotaped. Fourteen physical examination components were measured, ranging from assessment of vibratory sense (5%) to measurement of blood pressure (98%). Provision of 10 services recommended by the National Cancer Institute to standardized patients included 16% being advised to reduce dietary fat; 53% to do monthly breast self-examination; 74% to quit smoking; and 89% to obtain a mammogram. Physicians spent from 5 to 60 minutes with the patients. Two physicians did not charge, whereas others charged from $24 to $108. Study group assignment was not associated with statistical differences in provider performance. Two standardized patients (3%) were detected by physicians. Audiotapes were used to verify the actresses' ability to replicate their scenario (consistently repeat their performance) and to verify physician performance. Physician responses to an identical patient request varied widely in terms of time spent with the patient, the services provided, and the cost of the visit. Using standardized

    2016-02-01

    Energy harvested from surface ocean waves and tidal currents has the potential to be a significant source of green energy, particularly for countries with extensive coastlines such as Japan. As part of a larger marine renewable energy project*, The University of Tokyo (in cooperation with JAMSTEC) has conducted a state-of-the-art wave resource assessment (with uncertainty estimates) to assist with wave generator site identification and construction in Japan. This assessment will be publicly available and is based on a large-scale NOAA WAVEWATCH III (version 4.18) simulation using NCEP and JAMSTEC forcings. It includes several key components to improve model skill: a 20-year simulation to reduce aleatory uncertainty, a four-nested-layer approach to resolve a 1 km shoreline, and finite-depth and current effects included in all wave power density calculations. This latter component is particularly important for regions near strong currents such as the Kuroshio. Here, we will analyze the different wave power density equations, discuss the model setup, and present results from the 20-year assessment (with a focus on the role of wave-current interactions). Time permitting, a comparison will also be made with simulations using JMA MSM 5 km winds. *New Energy and Industrial Technology Development Organization (NEDO): "Research on the Framework and Infrastructure of Marine Renewable Energy; an Energy Potential Assessment"

  8. The Impact of Excluding Food Guarding from a Standardized Behavioral Canine Assessment in Animal Shelters

    Directory of Open Access Journals (Sweden)

    Heather Mohan-Gibbons

    2018-02-01

    Full Text Available Many shelters euthanize or restrict adoptions for dogs that exhibit food guarding while in the animal shelter. However, previous research showed that only half the dogs exhibiting food guarding during an assessment food guard in the home. So, dogs are often misidentified as future food guarders during shelter assessments. We examined the impact of shelters omitting food guarding assessments. Nine shelters conducted a two-month baseline period of assessing for food guarding followed by a two-month investigative period during which they omitted the food guarding assessment. Dogs that guarded their food during a standardized assessment were less likely to be adopted, had a longer shelter stay, and were more likely to be euthanized. When the shelters stopped assessing for food guarding, there was no significant difference in the rate of returns of food guarding dogs, even though more dogs were adopted because fewer were identified with food guarding behavior. Additionally, the number of injuries to staff, volunteers, and adopters was low (104 incidents from a total of 14,180 dogs and did not change when the food guarding assessment was omitted. These results support a recommendation that shelters discontinue the food guarding assessment.

    2017-04-01

    Under the US Clean Water Act, wetland restoration is used to compensate for adverse impacts to wetlands. Following construction, compensation wetlands are monitored for approximately 5 years to determine if they comply with project-specific performance standards. Once a compensation site complies with performance standards, it is assumed that the site will continue to meet standards indefinitely. However, there have been few assessments of long-term compliance. We surveyed, in 2012, 30 compensation sites 8-20 years after restoration to determine whether projects continued to meet performance standards. Additionally, we compared floristic quality of compensation sites to the quality of adjacent natural wetlands to determine whether wetland condition in compensation sites could be predicted based on the condition of nearby wetlands. Compensation sites met, on average, 65% of standards during the final year of monitoring and 53% of standards in 2012, a significant decrease in compliance. Although forested wetlands often failed to meet standards for planted tree survival, the temporal decrease in compliance was driven by increasing dominance by invasive plants in emergent wetlands. The presumption of continued compliance with performance standards after a 5-year monitoring period was not supported. Wetlands restored near better quality natural wetlands achieved and maintained greater floristic quality, suggesting that landscape context was an important determinant of long-term restoration outcomes. Based on our findings, we recommend that compensation wetlands should be monitored for longer time periods, and we suggest that nearby or adjacent natural wetlands provide good examples of reasonably achievable restoration outcomes in a particular landscape.

    This report updates a baseline risk assessment for the 300 Area prepared in 1994. The update includes consideration of changes in contaminants of interest and in the environment that have occurred during the period of interim remedial action, i.e., 1996 to the present, as well as the sub-regions, for which no initial risk assessments have been conducted. In 1996, a record of decision (ROD) stipulated interim remedial action for groundwater affected by releases from 300 Area sources, as follows: (a) continued monitoring of groundwater that is contaminated above health-based levels to ensure that concentrations continue to decrease, and (b) institutional controls to ensure that groundwater use is restricted to prevent unacceptable exposure to groundwater contamination. In 2000, the groundwater beneath the two outlying sub-regions was added to the operable unit. In 2001, the first 5-year review of the ROD found that the interim remedy and remedial action objectives were still appropriate, although the review called for additional characterization activities. This report includes a current conditions baseline ecological and human health risk assessment using maximum concentrations in the environmental media of the 300-FF-5 Operable Unit and downstream conditions at the City of Richland, Washington. The scope for this assessment includes only current measured environmental concentrations and current use scenarios. Future environmental concentrations and future land uses are not considered in this assessment.

  13. Towards a Quantitative Performance Measurement Framework to Assess the Impact of Geographic Information Standards

    Vandenbroucke, D.; Van Orshoven, J.; Vancauwenberghe, G.

    2012-12-01

    Over the last decennia, the use of Geographic Information (GI) has gained importance, in public as well as in private sector. But even if many spatial data and related information exist, data sets are scattered over many organizations and departments. In practice it remains difficult to find the spatial data sets needed, and to access, obtain and prepare them for using in applications. Therefore Spatial Data Infrastructures (SDI) haven been developed to enhance the access, the use and sharing of GI. SDIs consist of a set of technological and non-technological components to reach this goal. Since the nineties many SDI initiatives saw light. Ultimately, all these initiatives aim to enhance the flow of spatial data between organizations (users as well as producers) involved in intra- and inter-organizational and even cross-country business processes. However, the flow of information and its re-use in different business processes requires technical and semantic interoperability: the first should guarantee that system components can interoperate and use the data, while the second should guarantee that data content is understood by all users in the same way. GI-standards within the SDI are necessary to make this happen. However, it is not known if this is realized in practice. Therefore the objective of the research is to develop a quantitative framework to assess the impact of GI-standards on the performance of business processes. For that purpose, indicators are defined and tested in several cases throughout Europe. The proposed research will build upon previous work carried out in the SPATIALIST project. It analyzed the impact of different technological and non-technological factors on the SDI-performance of business processes (Dessers et al., 2011). The current research aims to apply quantitative performance measurement techniques - which are frequently used to measure performance of production processes (Anupindi et al., 2005). Key to reach the research objectives

    2015-06-01

    Physician-patient communication is vital to patient care, and physician-nurse interactions are equally critical. Conflict between nurses and physicians can greatly impair communication, increasing the risk of treatment errors, yet physicians receive little education during training on recognizing and resolving professional conflicts. We created and implemented the Standardized Professional (S-Pro) Encounter to improve training and provide opportunities to evaluate resident professionalism and communication with health care team colleagues. The standardized patient model is well established for teaching and assessing clinical and communication skills. Using the standardized patient concept, we created a nurse-resident encounter with 2 professionally trained medical portrayers (1 "nurse," 1 "patient"), in which the nurse disagrees with the resident's treatment plan. Residents were surveyed for prior experience with nurse-physician conflict management, and we assessed postencounter for collaborative skills and conflict resolution. All residents (n=18) observed at least 1 physician-nurse conflict in front of patients. Eleven (61%) reported being involved in at least 1 conflict. Twelve residents (67%) had 2 or fewer prior education experiences in interprofessional conflict management. Faculty assessment and S-Pro scores demonstrated high agreement, while resident self-assessment scores demonstrated low agreement with faculty and S-Pro scores. Participants and evaluators found the encounter to be reasonably authentic. There was strong agreement between the faculty and S-Pro assessment of resident performance when using the Boggs scale. The S-Pro Encounter is easily adapted for other clinical situations or training programs, and facilitates the assessment of professionalism and communication skills between residents and other health care professionals.

  15. Mannequin or standardized patient: participants' assessment of two training modalities in trauma team simulation

    Directory of Open Access Journals (Sweden)

    Wisborg Torben

    2009-01-01

    Full Text Available Abstract Background Trauma team training using simulation has become an educational compensation for a low number of severe trauma patients in 49 of Norway's 50 trauma hospitals for the last 12 years. The hospitals' own simple mannequins have been employed, to enable training without being dependent on expensive and advanced simulators. We wanted to assess the participants' assessment of using a standardized patient instead of a mannequin. Methods Trauma teams in five hospitals were randomly exposed to a mannequin or a standardized patient in two consecutive simulations for each team. In each hospital two teams were trained, with opposite order of simulation modality. Anonymous, written questionnaires were answered by the participants immediately after each simulation. The teams were interviewed as a focus group after the last simulation, reflecting on the difference between the two simulation modalities. Outcome measures were the participants' assessment of their own perceived educational outcome and comparison of the models, in addition to analysis of the interviews. Results Participants' assessed their educational outcome to be high, and unrelated to the order of appearance of patient model. There were no differences in assessment of realism and feeling of embarrassment. Focus groups revealed that the participants felt that the choice between educational modalities should be determined by the simulated case, with high interaction between team and patient being enhanced by a standardized patient. Conclusion Participants' assessment of the outcome of team training seems independent of the simulation modality when the educational goal is training communication, co-operation and leadership within the team.

    Full Text Available This paper identifies trends in secondary school accounting participation and achievement during the firstfive years of the full implementation of the National Certificate of Educational Achievement (NCEA in NewZealand schools. NCEA marks a shift from a norm-referenced assessment regime to standards-basedassessment. Literature suggests that standards-based assessment increases the academic performance ofminority ethnic groups (such as Maori and Pacific Island students, and low socio-economic status (SESstudents. The author pays particular attention to these groups and his analysis reveals some interestingresults: in accounting, the NCEA has not met expectations for these students. From 2004 to 2008, thenumber of low SES accounting students has dropped, as has the number of accounting standards entered andthe rates of achievement. Likewise, there has been no significant improvement in the academic performanceof Maori students taking accounting standards, while Pacific Island students have experienced a significantdecrease in achievement. The author also discusses how studying high school accounting impacts on tertiarylevel study and offers some future implications of this research.

    For peer review of teaching to be credible and reliable, peer raters must be trained to identify and measure teaching behaviors accurately. Peer rater training, therefore, must be based on expert-derived rating standards of teaching performance. The authors sought to establish precise lecture rating standards for use in peer rater training at their school. From 2008 to 2010, a panel of experts, who had previously helped to develop an instrument for the peer assessment of lecturing, met to observe, discuss, and rate 40 lectures, using a consensus-building model to determine key behaviors and levels of proficiency for each of the instrument's 11 criteria. During this process, the panelists supplemented the original instrument with precise behavioral descriptors of lecturing. The reliability of the derived rating standards was assessed by having the panelists score six sample lectures independently. Intraclass correlation coefficients of the panelists' ratings of the lectures ranged from 0.75 to 0.96. There was moderate to high positive association between 10 of the 11 instrument's criteria and the overall performance score (r = 0.752-0.886). There were no statistically significant differences among raters in terms of leniency or stringency of scores. Two relational themes, content and style, were identified within the instrument's variables. Recommendations for developing expert-derived ratings standards include using an interdisciplinary group for observation, discussion, and verbal identification of behaviors; asking members to consider views that contrast with their own; and noting key teaching behaviors for use in future peer rater training.

    In general, reliable studies are well designed and well performed, and enough details on study design and performance are reported to assess the study. For hazard and risk assessment in various legal frameworks, many different types of ecotoxicity studies need to be evaluated for reliability. These studies vary in study design, methodology, quality, and level of detail reported (e.g., reviews, peer-reviewed research papers, or industry-sponsored studies documented under Good Laboratory Practice [GLP] guidelines). Regulators have the responsibility to make sound and verifiable decisions and should evaluate each study for reliability in accordance with scientific principles regardless of whether they were conducted in accordance with GLP and/or standardized methods. Thus, a systematic and transparent approach is needed to evaluate studies for reliability. In this paper, 8 different methods for reliability assessment were compared using a number of attributes: categorical versus numerical scoring methods, use of exclusion and critical criteria, weighting of criteria, whether methods are tested with case studies, domain of applicability, bias toward GLP studies, incorporation of standard guidelines in the evaluation method, number of criteria used, type of criteria considered, and availability of guidance material. Finally, some considerations are given on how to choose a suitable method for assessing reliability of ecotoxicity studies. Integr Environ Assess Manag 2017;13:640-651. © 2016 The Authors.

    Full Text Available Abstract Background The purpose of this study was to compare diagnostic performance for the detection of caries using photographs with an established visual examination method and histological sections as the reference standard. Methods 50 extracted permanent teeth were assessed for the presence of occlusal caries by 9 examiners using two methods; traditional visual examination developed by BASCD and photographs produced by an intra-oral camera. For both methods, diagnoses were made at “caries into dentine” level. The teeth were histologically sectioned and the diagnostic decisions using visual and photographic assessment were compared to the histological reference standard. Inter- and intra- examiner reliability for the methods was assessed and weighted kappa values were calculated. Results The visual examination method had a median sensitivity value of 65.6% and a median specificity value of 82.4%. The photographic assessments method had a median sensitivity of 81.3% and a median specificity of 82.4%. Conclusions The photographic assessments method had a higher sensitivity for caries detection than the visual examination. The two methods had comparable specificities and good intra- and inter- examiner reliability.

    Full Text Available The evaluation is not enough to improve education necessary but. There are no magic to educational problems through assessment solutions. However, the evaluation, in partnership with the methodology, should be treated as determinants of the quality and improving education. Surely, many teachers agree that it is not easy to design assessment tools that are consistent with the teaching-learning competence and, in turn, with rigorous curriculum standards and assessment of the Autonomous Community. However, this difficulty should not be considered as an impossibility. Through this article aims to contribute to building an improvement plan associated with the design of the evaluation instruments from different areas or subjects. Such a design should be based on at least the following: I want to evaluate (referring to assessment criteria and standards of assessable learning included in the instrument and I will evaluate (referencing jurisdictional situations linked to next and known student context, HOW I WILL QUALIFY (preserving the right of students to an objective evaluation and what consequences they will have the results for the different agents that make up the educational community.

    Many municipal activities require updated large-scale maps that include both topographic and thematic information. For this purpose, the efficient use of very high spatial resolution (VHR) satellite imagery suggests the development of approaches that enable a timely discrimination, counting and delineation of urban elements according to legal technical specifications and quality standards. Therefore, the nature of this data source and expanding range of applications calls for objective methods and quantitative metrics to assess the quality of the extracted information which go beyond traditional thematic accuracy alone. The present work concerns the development and testing of a new approach for using technical mapping standards in the quality assessment of buildings automatically extracted from VHR satellite imagery. Feature extraction software was employed to map buildings present in a pansharpened QuickBird image of Lisbon. Quality assessment was exhaustive and involved comparisons of extracted features against a reference data set, introducing cartographic constraints from scales 1:1000, 1:5000, and 1:10,000. The spatial data quality elements subject to evaluation were: thematic (attribute) accuracy, completeness, and geometric quality assessed based on planimetric deviation from the reference map. Tests were developed and metrics analyzed considering thresholds and standards for the large mapping scales most frequently used by municipalities. Results show that values for completeness varied with mapping scales and were only slightly superior for scale 1:10,000. Concerning the geometric quality, a large percentage of extracted features met the strict topographic standards of planimetric deviation for scale 1:10,000, while no buildings were compliant with the specification for scale 1:1000.

    2009-05-01

    The Test Of Astronomy STandards (TOAST) assessment instrument is a multiple-choice survey tightly aligned to the consensus learning goals stated by the American Astronomical Society - Chair's Conference on ASTRO 101, the American Association of the Advancement of Science's Project 2061 Benchmarks, and the National Research Council's National Science Education Standards. Researchers from the Cognition in Astronomy, Physics and Earth sciences Research (CAPER) Team at the University of Wyoming's Science and Math Teaching Center (UWYO SMTC) have been conducting a question-by-question distractor analysis procedure to determine the sensitivity and effectiveness of each item. In brief, the frequency each possible answer choice, known as a foil or distractor on a multiple-choice test, is determined and compared to the existing literature on the teaching and learning of astronomy. In addition to having statistical difficulty and discrimination values, a well functioning assessment item will show students selecting distractors in the relative proportions to how we expect them to respond based on known misconceptions and reasoning difficulties. In all cases, our distractor analysis suggests that all items are functioning as expected. These results add weight to the validity of the Test Of Astronomy STandards (TOAST) assessment instrument, which is designed to help instructors and researchers measure the impact of course-length duration instructional strategies for undergraduate science survey courses with learning goals tightly aligned to the consensus goals of the astronomy education community.

    Morphological embryo classification is of great importance for many laboratory techniques, from basic research to the ones applied to assisted reproductive technology. However, the standard classification method for both human and cattle embryos, is based on quality parameters that reflect the overall morphological quality of the embryo in cattle, or the quality of the individual embryonic structures, more relevant in human embryo classification. This assessment method is biased by the subjectivity of the evaluator and even though several guidelines exist to standardize the classification, it is not a method capable of giving reliable and trustworthy results. Latest approaches for the improvement of quality assessment include the use of data from cellular metabolism, a new morphological grading system, development kinetics and cleavage symmetry, embryo cell biopsy followed by pre-implantation genetic diagnosis, zona pellucida birefringence, ion release by the embryo cells and so forth. Nowadays there exists a great need for evaluation methods that are practical and non-invasive while being accurate and objective. A method along these lines would be of great importance to embryo evaluation by embryologists, clinicians and other professionals who work with assisted reproductive technology. Several techniques shows promising results in this sense, one being the use of digital images of the embryo as basis for features extraction and classification by means of artificial intelligence techniques (as genetic algorithms and artificial neural networks). This process has the potential to become an accurate and objective standard for embryo quality assessment.

    Background Medication nonadherence is a major problem in chronic kidney failure patients undergoing dialysis. Pharmacists play a vital role in improving medication-related patient outcomes, reducing drug-related problems, and improving medication adherence. However, little is known about how pharmacists assess medication adherence in dialysis patients. Objective To measure pharmacists' perceptions, current practices, and barriers to assessing adherence in dialysis patients. Setting Australian renal-specialised pharmacists. Method An online survey was conducted between March and May 2016. Survey included five psychometric scales measuring perceived prevalence, contributors, effective methods, barriers, and confidence to assess adherence on a 10-point Likert scale (1 = strongly disagree; 10 = strongly agree). Current practices were identified using a 4-point graded response (1 = do not practice; 4 = practice for all). Perception scores, scale reliability, and responses to current practices questionnaire. Results 41 pharmacists completed the survey (response rate, 91.1%). The majority (91.9%, n = 34; median = 8.0) agreed patients were nonadherent to medication. Time constraints (43.8%, n = 14) and hospital support (31.3%, n = 10) were perceived as barriers to assessment. Objective blood monitoring was frequently used to determine nonadherence (57.1%, n = 16), whereas subjective interviews were rarely conducted (27.6%, n = 8). Though all pharmacists support the presence of dedicated pharmacist for assessing adherence (100.0%, n = 33), only 24.2% were actually performing this function. Conclusion Pharmacists were rarely assigned for adherence assessment in dialysis settings. Established self-report methods were under-utilised compared to objective methods. Future research should investigate the effectiveness of pharmacists' involvement in facilitating adherence promotion and early identification of medication-related issues in dialysis patients.

    Full Text Available Background : The first step in controlling pollutants is to measure and analyze them, because comparing them with standards and practically controlling them will not become possible without full awareness of the qualities and quantities of pollutants. The present study was conducted to assess and determine the amount of volatile organic compounds in the air in Khorramabad, Iran. Methods and Materials: The present research is a descriptive study. On the whole, a total of 144 samples were randomly taken from the air in Khorramabad during one year. Sampling was done through an environmental sampling pump and activated carbon absorbent tubes. The sampling method the continuous random 24-hour type. The preparation of the samples and the extraction of the pollutants were carried out by solvent carbon disulfide. The samples were analyzed using Gas Chromatography – Mass Spectrometry (GC-MS device equipped with capillary columns. Data analysis was conducted using SPSS 17 and t-tests. Results: The results of the present study showed that the total concentration of the volatile organic compounds (VOCs in the air of Khorramabad was 1140.9 µg/m3, which was about 7 times greater than the maximum acceptable amount set by USEPA (United States Environmental Protection Agency. Additionally, the findings of the present research indicate that, totally the mean concentration of all volatile organic compounds in different areas of the city of Khorramabad was higher than the permissible level set by EPA for breathable air. The comparison of the mean concentration of VOCs in the air in Khorramabad in the warm and cold seasons using the t-test indicated that there is a significant relationship between the concentrations of benzene and toluene and the season of the year (p < 0.05. But for the other identified hydrocarbons no significant relationship was found despite the fact that they have higher concentrations during the warm season. Conclusion: Regarding the

    Purpose Although language samples and standardized tests are regularly used in assessment, few studies provide clinical guidance on how to synthesize information from these testing tools. This study extends previous work on the relations between tests and language samples to a new population—school-age bilingual speakers with primary language impairment—and considers the clinical implications for bilingual assessment. Method Fifty-one bilingual children with primary language impairment completed narrative language samples and standardized language tests in English and Spanish. Children were separated into younger (ages 5;6 [years;months]–8;11) and older (ages 9;0–11;2) groups. Analysis included correlations with age and partial correlations between language sample measures and test scores in each language. Results Within the younger group, positive correlations with large effect sizes indicated convergence between test scores and microstructural language sample measures in both Spanish and English. There were minimal correlations in the older group for either language. Age related to English but not Spanish measures. Conclusions Tests and language samples complement each other in assessment. Wordless picture-book narratives may be more appropriate for ages 5–8 than for older children. We discuss clinical implications, including a case example of a bilingual child with primary language impairment, to illustrate how to synthesize information from these tools in assessment.

    Frequent skin cleaning fulfils the definition of occupational 'wet work'. Standardized methods are required to assess the irritation potential of workplace cleansers. To develop a standardized procedure for testing the irritation potential of occupational skin cleansers. In this single-blind, single-centre trial in 25 healthy volunteers, the irritation potential of five generic reference cleansers was tested by three-times-daily washing with an automated skin cleaning device for 4 days, and quantification of cumulative skin barrier damage was performed by visual scoring, chromametry, transepidermal water loss TEWL, and corneometry. For two cleansers, reproducibility of the irritancy assessment was assessed. Furthermore, the irritation induced by four commercial workplace skin cleansers was studied. Whereas no significant changes were observed for any of the tested cleansers by either visual scoring or chromametry, significant increases in TEWL and significant decreases in stratum corneum hydration were found for all cleansers. Cleansers differed significantly in their irritation potential. On retesting of two cleansers, the first results were confirmed. Among the four commercial cleansers, one that was claimed to be mild was found to be disproportionally irritant. The presented model for testing cleansing preparations allows a highly controlled, practically relevant and reproducible irritancy assessment of occupational skin cleansers. © 2013 John Wiley & Sons A/S.

    Full Text Available “Global Learning” with shared learning contents, resources, activities and goals is one of the contributions of Globalization. With the capability to use new Information and Communication Technologies (ICT it is a bit easier to have a technology based learning systems that enable learners to share the learning resources and possibilities. As a result many Learning Management Systems (LMS were developed with divers of platforms and approaches. Consequently, sharing learning resources and components has become a major challenge. E-assessment as a primary activity of any LMS is facing the same challenges and problems. In order to stand on this challenge people in the field of technology enhanced learning have recommended that LMS should conform to specific standards. This paper discuses this challenge, the consequences and limitations of standards in the modern learning settings. Moreover, it shows a service oriented framework for assessment which aims to make the e-assessment systems flexible and also to initiate the term of “Global Learning Assessment” with the possibility of sharing the e-assessment system components.

    Wound-healing outcomes applying standardized protocols have typically been measured within controlled clinical trials, not natural settings. Standardized protocols of wound care have been validated for clinical use, creating an opportunity to measure the resulting outcomes. Wound-healing outcomes were explored during clinical use of standardized validated protocols of care based on patient and wound assessments. This was a prospective multicenter study of wound-healing outcomes management in real-world clinical practice. Healing outcomes from March 26 to October 31, 2001, were recorded on patients in 3 long-term care facilities, 1 long-term acute care hospital, and 12 home care agencies for wounds selected by staff to receive care based on computer-generated validated wound care algorithms. After diagnosis, wound dimensions and status were assessed using a tool adapted from the Pressure Sore Status Toolfor use on all wounds. Wound, ostomy, and continence nursing professionals accessed consistent protocols of care, via telemedicine in home care or paper forms in long-term care. A physician entered assessments into a desktop computer in the wound clinic. Based on evidence that healing proceeds faster with fewer infections in environments without gauze, the protocols generally avoided gauze dressings. Most of the 767 wounds selected to receive the standardized-protocols of care were stage III-IV pressure ulcers (n = 373; mean healing time 62 days) or full-thickness venous ulcers (n = 124; mean healing time 57 days). Partial-thickness wounds healed faster than same-etiology full-thickness wounds. These results provide benchmarks for natural-setting healing outcomes and help to define and address wound care challenges. Outcomes primarily using nongauze protocols of care matched or surpassed best previously published results on similar wounds using gauze-based protocols of care, including protocols applying gauze impregnated with growth factors or other agents.

  1. Global Risk Assessment of Aflatoxins in Maize and Peanuts: Are Regulatory Standards Adequately Protective?

    Science.gov (United States)

    Wu, Felicia

    2013-01-01

    The aflatoxins are a group of fungal metabolites that contaminate a variety of staple crops, including maize and peanuts, and cause an array of acute and chronic human health effects. Aflatoxin B1 in particular is a potent liver carcinogen, and hepatocellular carcinoma (HCC) risk is multiplicatively higher for individuals exposed to both aflatoxin and chronic infection with hepatitis B virus (HBV). In this work, we sought to answer the question: do current aflatoxin regulatory standards around the world adequately protect human health? Depending upon the level of protection desired, the answer to this question varies. Currently, most nations have a maximum tolerable level of total aflatoxins in maize and peanuts ranging from 4 to 20ng/g. If the level of protection desired is that aflatoxin exposures would not increase lifetime HCC risk by more than 1 in 100,000 cases in the population, then most current regulatory standards are not adequately protective even if enforced, especially in low-income countries where large amounts of maize and peanuts are consumed and HBV prevalence is high. At the protection level of 1 in 10,000 lifetime HCC cases in the population, however, almost all aflatoxin regulations worldwide are adequately protective, with the exception of several nations in Africa and Latin America.

    Research in emergencies is needed to understand the prevalence of mental health and psychosocial problems and strengthen the evidence base for interventions. All research - including operational needs assessments, programme monitoring and evaluation, and formal academic research - must be conducted ethically. While there is broad consensus on fundamental principles codified in research ethics guidelines, these do not address the ethical specificities of conducting mental health and psychosocial support (MHPSS) research with adults in emergencies. To address this gap, this paper presents a review of multidisciplinary literature to identify specific ethical principles applicable to MHPSS research in emergencies. Fifty-nine sources meeting the literature review inclusion criteria were analysed following a thematic synthesis approach. There was consensus on the relevance of universal ethical research principles to MHPSS research in emergencies, including norms of participant informed consent and protection; ensuring benefit arises from research participation; researcher neutrality, accountability, and safety; and the duty to ensure research is well designed and accounts for contextual factors in emergency settings. We go onto discuss unresolved issues by highlighting six current debates relating to the application of ethics in emergency settings: (1) what constitutes fair benefits?; (2) how should informed consent be operationalised?; (3) is there a role for decision making capacity assessments?; (4) how do risk management approaches impact upon the construction of ethical research?; (5) how can ethical reflection best be achieved?, and (6) are ethical review boards sufficiently representative and equipped to judge the ethical and scientific merit of emergency MHPSS research? Underlying these debates is a systemic tension between procedural ethics and ethics in practice. In summary, underpinning the literature is a desire to ensure the protection of participants

    Professionalism is a critically important competency that must be evaluated in medical trainees but is a complex construct that is hard to assess. A systematic review was undertaken to give insight into the current best practices for assessment of professionalism in medical trainees and to identify new research priorities in the field. A search was conducted on PubMed for behavioral assessments of medical students and residents among the United States and Canadian allopathic schools in the last 15 years. An initial search yielded 594 results, 28 of which met our inclusion criteria. Our analysis indicated that there are robust generic definitions of the major attributes of medical professionalism. The most commonly used assessment tools are survey instruments that use Likert scales tied to attributes of professionalism. While significant progress has been made in this field in recent years, several opportunities for system-wide improvement were identified that require further research. These include a paucity of information about assessment reliability, the need for rater training, a need to better define competency in professionalism according to learner level (preclinical, clerkship, resident etc.) and ways to remediate lapses in professionalism. Student acceptance of assessment of professionalism may be increased if assessment tools are shifted to better incorporate feedback. Tackling the impact of the hidden curriculum in which students may observe lapses in professionalism by faculty and other health care providers is another priority for further study. PMID:28652951

    Full Text Available Drought assessment is essential for coping with frequent droughts nowadays. Owing to the large spatio-temporal variations in hydrometeorology in most regions in China, it is very necessary to use a physically-based hydrological model to produce rational spatial and temporal distributions of hydro-meteorological variables for drought assessment. In this study, the large-scale distributed hydrological model Variable Infiltration Capacity (VIC was coupled with a modified standardized runoff index (SRI for drought assessment in the Weihe River basin, northwest China. The result indicates that the coupled model is capable of reasonably reproducing the spatial distribution of drought occurrence. It reflected the spatial heterogeneity of regional drought and improved the physical mechanism of SRI. This model also has potential for drought forecasting, early warning and mitigation, given that accurate meteorological forcing data are available.

    This study analyzes impacts from energy efficiency standards and labeling in Mexico from 1994 through 2005 for four major products: household refrigerators, room air conditioners, three-phase (squirrel cage) induction motors, and clothes washers. It is a retrospective analysis, seeking to assess verified impacts on product efficiency in the Mexican market in the first ten years after standards were implemented. Such an analysis allows the Mexican government to compare actual to originally forecast program benefits. In addition, it provides an extremely valuable benchmark for other countries considering standards, and to the energy policy community as a whole. The methodology for evaluation begins with historical test data taken for a large number of models of each product type between 1994 and 2005. The pre-standard efficiency of models in 1994 is taken as a baseline throughout the analysis. Model efficiency data were provided by an independent certification laboratory (ANCE), which tested products as part of the certification and enforcement mechanism defined by the standards program. Using this data, together with economic and market data provided by both government and private sector sources, the analysis considers several types of national level program impacts. These include: Energy savings; Environmental (emissions) impacts, and Net financial impacts to consumers, manufacturers and utilities. Energy savings impacts are calculated using the same methodology as the original projections, allowing a comparison. Other impacts are calculated using a robust and sophisticated methodology developed by the Instituto de Investigaciones Electricas (IIE) and Lawrence Berkeley National Laboratory (LBNL), in a collaboration supported by the Collaborative Labeling and Standards Program (CLASP).

    Implementation of microbial fuel cells (MFCs) for electricity production requires effective current generation from waste products via robust cathode reduction. Three cathode types using dissolved oxygen cathodes (DOCs), ferricyanide cathodes (FeCs) and air cathodes (AiCs) were therefore assessed...... responses to substrate loading rates and external resistance. At the lowest external resistance of 27 and highest substrate loading rate of 2 g chemical oxygen demand (COD) per Lday, FeC-MFC generated highest average current density (1630 mA/m(2)) followed by AiC-MFC (802 mA/m(2)) and DOC-MFC (184 mA/m(2......)). Electrochemical impedance spectroscopy (EIS) was used to determine the impedance of the cathodes. It was thereby confirmed that the FeC-MFC produced the highest current density with the lowest internal resistance for the cathode. However, in a setup using bioethanol effluent, the AiC-MFC was concluded...

    Chamberlain, Jude; Huprich, Steven K

    2011-10-01

    The Depressive Personality Disorder Inventory (DPDI; Huprich, Margrett, Barthelemy, & Fine, 1996; see Appendix) was created to assess Depressive Personality Disorder in clinical and nonclinical samples. Since its creation, the DPDI has been used in multiple studies, and the psychometric properties of the measure have generally supported its reliability, convergent validity, and construct validity; however, evidence for the measure's discriminant validity has been mixed. Specifically, the DPDI tends to correlate highly with measures of current depressive symptoms, which limits its efficacy in differentiating current depressive symptoms from a depressive personality structure. A principal components analysis of 362 individuals who completed both the DPDI and Beck Depression Inventory (BDI-II; Beck, Steer, & Brown, 1996) found that 49% of the variance was accounted for in two components. Seven items from the DPDI loaded more strongly on the first component composed of many BDI-II items. These items were removed in order to create a measure believed to assess DPD without the confounding influence of current depressive symptomology. Principal components analysis of the revised measure yielded three components, accounting for 46% of the variance. The revised DPDI was used to calculate convergent, discriminant, and construct validity coefficients from measures used in former studies. Virtually no improvement in the validity coefficients was observed. It is concluded that assessing DPD via self-report is limited in its utility.

    For the quantitative assessment of dopamine transporter (DAT) using [123I]FP-CIT single-photon emission computed tomography (SPECT) (DaTscan), anatomic standardization is preferable for achieving objective and user-independent quantification of striatal binding using a volume-of-interest (VOI) template. However, low accumulation of DAT in Parkinson's disease (PD) would lead to a deformation error when using a DaTscan-specific template without any structural information. To avoid this deformation error, we applied computed tomography (CT) data obtained using SPECT/CT equipment to anatomic standardization. We retrospectively analyzed DaTscan images of 130 patients with parkinsonian syndromes (PS), including 80 PD and 50 non-PD patients. First we segmented gray matter from CT images using statistical parametric mapping 12 (SPM12). These gray-matter images were then anatomically standardized using the diffeomorphic anatomical registration using exponentiated Lie algebra (DARTEL) algorithm. Next, DaTscan images were warped with the same parameters used in the CT anatomic standardization. The target striatal VOIs for decreased DAT in PD were generated from the SPM12 group comparison of 20 DaTscan images from each group. We applied these VOIs to DaTscan images of the remaining patients in both groups and calculated the specific binding ratios (SBRs) using nonspecific counts in a reference area. In terms of the differential diagnosis of PD and non-PD groups using SBR, we compared the present method with two other methods, DaTQUANT and DaTView, which have already been released as software programs for the quantitative assessment of DaTscan images. The SPM12 group comparison showed a significant DAT decrease in PD patients in the bilateral whole striatum. Of the three methods assessed, the present CT-guided method showed the greatest power for discriminating PD and non-PD groups, as it completely separated the two groups.

    High definition (HD) digital imaging represents a major advance in endoscope technology. The development of the charge-coupled device chip and its location at the distal end of the endoscope allows for image capture and digitization, as well as specific light filtration and processing. We assessed the capability of HD technology combined with digital imaging to provide improved image quality and enhanced spatial three-dimensional positioning. A HD digital laparoscope and a standard definition (SD) laparoscope were evaluated in the laboratory setting to assess and compare image resolution, brightness, contrast, and color reproducibility, using standard industry testing protocols. Compared with the SD laparoscope, the HD laparoscope had superior resolution at 50 mm distance (2.4 line pairs/mm v 2.0 line pairs/mm), increased image brightness (129 lumens v 112 lumens), increased depth of field, and decreased distortion. Color and grayscale reproduction were found to be similar for the two laparoscopes. HD laparoscopy has superior objective performance characteristics compared with standard laparoscopes. Further investigation is required to determine whether these objective findings translate into subjective improvements, and which characteristics can be adjusted to obtain the best possible results. These improved optics may lead to easier identification of anatomic structures, finer dissection, and enhanced three-dimensional spatial positioning during HD laparoscopic procedures.

    2013-06-01

    Recently, several researchers have attempted to address Deepwater Horizon incident environmental fate and effects issues using laboratory testing and extrapolation procedures that are not fully reliable measures for environmental assessments. The 2013 Rico-Martínez et al. publication utilized laboratory testing approaches that severely limit our ability to reliably extrapolate such results to meaningful real-world assessments. The authors did not adopt key methodological elements of oil and dispersed oil toxicity standards. Further, they drew real-world conclusions from static exposure tests without reporting actual exposure concentrations. Without this information, it is not possible to compare their results to other research or real spill events that measured and reported exposure concentrations. The 1990s' Chemical Response to Oil Spills: Ecological Effects Research Forum program was established to standardize and conduct exposure characterization in oil and dispersed oil aquatic toxicity testing (Aurand and Coelho, 2005). This commentary raises awareness regarding the necessity of standardized test protocols. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The US Nuclear Regulatory Commission (NRC) is initiating a new rulemaking project to develop a digital system common-cause failure (CCF) rule. This rulemaking will review and modify or affirm the NRC's current digital system CCF policy as discussed in the Staff Requirements Memorandum to the Secretary of the Commission, Office of the NRC (SECY) 93-087, Policy, Technical, and Licensing Issues Pertaining to Evolutionary and Advanced Light Water Reactor (ALWR) Designs, and Branch Technical Position (BTP) 7-19, Guidance on Evaluation of Defense-in-Depth and Diversity in Digital Computer-Based Instrumentation and Control Systems, as well as Chapter 7, Instrumentation and Controls, in NRC Regulatory Guide (NUREG)-0800, Standard Review Plan for Review of Safety Analysis Reports for Nuclear Power Plants (ML033580677). The Oak Ridge National Laboratory (ORNL) is providing technical support to the NRC staff on the CCF rulemaking, and this report is one of several providing the technical basis to inform NRC staff members. For the task described in this report, ORNL examined instrumentation and controls (I&C) technology implementations in nuclear power plants in the light of current CCF guidance. The intent was to assess whether the current position on CCF is adequate given the evolutions in digital safety system implementations and, if gaps in the guidance were found, to provide recommendations as to how these gaps could be closed.

    2017-10-01

    The authors’ expert assessment of the current state of the energy management system in the company is proposed in the article. The experts are invited to assess the status of the energy management system in the following categories: energy policy, organizational structure, training, motivation, control, communication, investment, and energy consumption culture. For the purposes of interpretation of the results of the expert evaluation obtained, a gradation based on a possible range of values is proposed. The expert evaluation allows representing the status of the energy management system in general and at each of its individual levels, which makes it possible to identify the problem areas more accurately. To confirm the applied nature of the proposed methodology, the authors assessed the opinions of 8 experts, employed by the road construction company of the Tyumen Region and related in one way or another to the process of energy consumption in the company due to the nature of their activities.

    The appropriate measurement of food security is critical for targeting food and economic aid; supporting early famine warning and global monitoring systems; evaluating nutrition, health, and development programs; and informing government policy across many sectors. This important work is complicated by the multiple approaches and tools for assessing food security. In response, we have prepared a compendium and review of food security assessment tools in which we review issues of terminology, measurement, and validation. We begin by describing the evolving definition of food security and use this discussion to frame a review of the current landscape of measurement tools available for assessing food security. We critically assess the purpose/s of these tools, the domains of food security assessed by each, the conceptualizations of food security that underpin each metric, as well as the approaches that have been used to validate these metrics. Specifically, we describe measurement tools that 1) provide national-level estimates of food security, 2) inform global monitoring and early warning systems, 3) assess household food access and acquisition, and 4) measure food consumption and utilization. After describing a number of outstanding measurement challenges that might be addressed in future research, we conclude by offering suggestions to guide the selection of appropriate food security metrics.

    Full Text Available New Zealand approaches to territorial landscape assessment have been strongly influenced by: research carried out in the United Kingdom in the 1970s, particularly visual quality assessments; and theoretical work from American universities during the 1970s and early 1980s. The visual emphasis of this work remained the focus of New Zealand landscape assessment into the early 1990s. However, a number of developments during the 1990s have encouraged a gradual readjustment of focus. Of particular significance have been: the introduction of the Resource Management Act 1991 (RMA91 with its holistic environmental perspective and broad-ranging landscape provisions; a greater bicultural awareness which recognises that Maori perspectives add different dimensions to mainstream landscape appreciation; and a highly competitive market economy where landscape investigations have to be cost effective and outcome focused. As a consequence of the introduction of the RMA91, many district and regional councils have commissioned landscape assessments. This paper considers the current situation of these district scale assessments and suggests ways of improving the assessment process.

    This work consisted of the assessment of humidification parameters and flow resistance for different heat and moisture exchanger filters (HMEF) used in intensive care unit. Four electrostatic HMEF were assessed: Hygrobac S (Tyco); Humidvent compact S (Teleflex); Hygrovent S/HME (Medisize-Dräger); Clear-Therm+HMEF (Intersurgical). Humidification parameters (loss of water weight, average absolute moisture [AAM], absolute variation of moisture) have been evaluated on a bench-test in conformity with the ISO 9360: 2000 standard, for 24h with the following ventilatory settings: tidal volume at 500 ml, respiratory rate at 15 c/min, and inspiration/expiration ratio at 1:1. The flow resistance of HMEFs assessed using the pressure drop method was measured before and after 24h of humidification for three increasing air flows of 30, 60, and 90 l/min. All the HMEFs allowed satisfactory level of humidification exceeding 30 mgH(2)O/l. The less powerful remained the Clear-Therm. Concerning HMEFs flow resistance, results showed a pressure drop slightly more important for the Hygrobac S filter as compared with other filters. This test showed differences between the HMEFs for both humidification and resistance parameters. When compared to the new version of the standards, HMEFs demonstrated their reliability. However, evolution of humidification and flow resistance characteristics over 24h showed a structural degradation of HMEFs, limiting their use over a longer period.

    Tracer methodology has been used by Accreditation Canada since 2008 to collect evidence on the quality and safety of care and services, and to assess compliance with accreditation standards. Given the importance of this methodology in the accreditation program, the objective of this study is to assess the quality of the methodology and identify its strengths and weaknesses. A mixed quantitative and qualitative approach was adopted to evaluate consistency, appropriateness, effectiveness and stakeholder synergy in applying the methodology. An online questionnaire was sent to 468 Accreditation Canada surveyors. According to surveyors' perceptions, tracer methodology is an effective tool for collecting useful, credible and reliable information to assess compliance with Qmentum program standards and priority processes. The results show good coherence between methodology components (appropriateness of the priority processes evaluated, activities to evaluate a tracer, etc.). The main weaknesses are the time constraints faced by surveyors and management's lack of cooperation during the evaluation of tracers. The inadequate amount of time allowed for the methodology to be applied properly raises questions about the quality of the information obtained. This study paves the way for a future, more in-depth exploration of the identified weaknesses to help the accreditation organization make more targeted improvements to the methodology.

    Full Text Available INTRODUCTION: Patients with schizophrenia elicit cognitive decline from the early phase of the illness. Mismatch negativity (MMN has been shown to be associated with cognitive function. We investigated the current source density of duration mismatch negativity (dMMN, by using low-resolution brain electromagnetic tomography (LORETA, and neuropsychological performance in subjects with early schizophrenia. METHODS: Data were obtained from 20 patients meeting DSM-IV criteria for schizophrenia or schizophreniform disorder, and 20 healthy control (HC subjects. An auditory odd-ball paradigm was used to measure dMMN. Neuropsychological performance was evaluated by the brief assessment of cognition in schizophrenia Japanese version (BACS-J. RESULTS: Patients showed smaller dMMN amplitudes than those in the HC subjects. LORETA current density for dMMN was significantly lower in patients compared to HC subjects, especially in the temporal lobes. dMMN current density in the frontal lobe was positively correlated with working memory performance in patients. CONCLUSIONS: This is the first study to identify brain regions showing smaller dMMN current density in early schizophrenia. Further, poor working memory was associated with decreased dMMN current density in patients. These results are likely to help understand the neural basis for cognitive impairment of schizophrenia.

    Variable adherence to standardized case definitions, clinical procedures, specimen collection techniques, and laboratory methods has complicated the interpretation of previous multicenter pneumonia etiology studies. To circumvent these problems, a program of clinical standardization was embedded in the Pneumonia Etiology Research for Child Health (PERCH) study. Between March 2011 and August 2013, standardized training on the PERCH case definition, clinical procedures, and collection of laboratory specimens was delivered to 331 clinical staff at 9 study sites in 7 countries (The Gambia, Kenya, Mali, South Africa, Zambia, Thailand, and Bangladesh), through 32 on-site courses and a training website. Staff competency was assessed throughout 24 months of enrollment with multiple-choice question (MCQ) examinations, a video quiz, and checklist evaluations of practical skills. MCQ evaluation was confined to 158 clinical staff members who enrolled PERCH cases and controls, with scores obtained for >86% of eligible staff at each time-point. Median scores after baseline training were ≥80%, and improved by 10 percentage points with refresher training, with no significant intersite differences. Percentage agreement with the clinical trainer on the presence or absence of clinical signs on video clips was high (≥89%), with interobserver concordance being substantial to high (AC1 statistic, 0.62-0.82) for 5 of 6 signs assessed. Staff attained median scores of >90% in checklist evaluations of practical skills. Satisfactory clinical standardization was achieved within and across all PERCH sites, providing reassurance that any etiological or clinical differences observed across the study sites are true differences, and not attributable to differences in application of the clinical case definition, interpretation of clinical signs, or in techniques used for clinical measurements or specimen collection.

    Diabetes mellitus is a highly prevalent multisystemic disorder with numerous potential complications and substantial socioeconomic consequences. In many cases, the patient history, physical examination and laboratory tests are not sufficient for a comprehensive evaluation of complicating disorders. Imaging modalities, such as sonography, computed tomography (CT) and magnetic resonance imaging (MRI) are of major significance in the evaluation of complicating disorders of diabetes according to current guidelines. Examples include assessment of coronary artery disease, peripheral artery disease, stroke and diabetic foot syndrome. Technical developments allow a substantial reduction in radiation dose and scan time in CT and MRI, respectively and could therefore justify a broader application in this patient population. In the future CT and MRI could also be used for the early detection of diabetic complications. Furthermore, they could also be used for risk stratification, e.g. measurement of hepatic fat content and evaluation of atherosclerosis in whole body MRI. Prior to widespread application of advanced imaging techniques in this patient population, improved outcomes with respect to survival, quality of life and cost-effectiveness need to be demonstrated. Diagnostic imaging modalities for the evaluation of the syndrome complex of diabetic disorders should be used according to the current guidelines but the use is predicted to increase given the high potential in this population.

    The current status of solid waste management in Lahore, a metropolitan city of Pakistan, is reviewed in this article using an existing approach, the UN-Habitat city profile. This involves a systematic quantitative and qualitative assessment of physical components and governance features of the current waste management system. A material flow diagram (MFD) is developed, which allows visualisation of the current waste management system with all related inputs and outputs. This study shows that in the current system, waste collection and transportation is the main focus, however the collection coverage is only about 68%. There is no controlled or even semi-controlled waste disposal facility in Lahore. There is no official recycling system in the city. It is estimated that currently ~27% of waste by weight is being recycled through the informal sector. Making use of the organic content of the waste, a composting facility is operative in the city, producing 47,230 tonnes year(-1) of organic compost. Lahore does not perform very well in governance features. Inclusivity of users and providers of the waste management system is low in the city, as not all stakeholders are consulted in the decision making processes. Waste management costs US$20 per tonne of waste, where the main focus is only on waste collection, and the current user fees are much lower than the actual costs. This study recommends that recycling should be promoted by increasing public awareness and integrating the informal sector to make the current system sustainable and financially viable. © The Author(s) 2014.

    Full Text Available Abstract Background Previously published studies have reported that up to 43% of patients with disorders of consciousness are erroneously assigned a diagnosis of vegetative state (VS. However, no recent studies have investigated the accuracy of this grave clinical diagnosis. In this study, we compared consensus-based diagnoses of VS and MCS to those based on a well-established standardized neurobehavioral rating scale, the JFK Coma Recovery Scale-Revised (CRS-R. Methods We prospectively followed 103 patients (55 ± 19 years with mixed etiologies and compared the clinical consensus diagnosis provided by the physician on the basis of the medical staff's daily observations to diagnoses derived from CRS-R assessments performed by research staff. All patients were assigned a diagnosis of 'VS', 'MCS' or 'uncertain diagnosis.' Results Of the 44 patients diagnosed with VS based on the clinical consensus of the medical team, 18 (41% were found to be in MCS following standardized assessment with the CRS-R. In the 41 patients with a consensus diagnosis of MCS, 4 (10% had emerged from MCS, according to the CRS-R. We also found that the majority of patients assigned an uncertain diagnosis by clinical consensus (89% were in MCS based on CRS-R findings. Conclusion Despite the importance of diagnostic accuracy, the rate of misdiagnosis of VS has not substantially changed in the past 15 years. Standardized neurobehavioral assessment is a more sensitive means of establishing differential diagnosis in patients with disorders of consciousness when compared to diagnoses determined by clinical consensus.

    Full Text Available Objective To investigate and evaluate whether the present physical examination standards for selection of pilot trainees meet the requirements for the medical selection of pilot trainees. Methods The experimental procedure was divided into three steps to evaluate the physical examination standards for the selection of pilot trainees. The first step was to compile a manual of investigation, which was composed of suitability assessments and the result of its use. The second step was to screen for specialists. A social science survey was adopted, and 119 specialists were selected composing 98 specialists in recruitment of pilots and 21 aviation medical clinicians. A total of 359 standard items were evaluated for suitability approval, and then the reliability of evaluation results was analyzed. The final step was the formation of criteria for final judgment. The worthiness of the items was based on the specialists' opinions. When a certain item was deemed suitable by more than 80% of the specialists, it was considered as appropriate, and when a certain item was deemed suitable by less than 60% of the specialists, it was not appropriate. Results A total of 134 survey brochures were sent out, and 128 out of 134 were retrieved. The positive index of specialist participation was 0.95, and the authority index was 0.86. 271 (75.5% of the 359 items were generally accepted by specialists as appropriate, and 27 (7.5% items were not accepted. Most of these rejected items involved function evaluation, the concept and essence of which could not be easily grasped. Conclusions Although the majority of the items in the physical examination standards were deemed appropriate by the specialists, there were a few items not accepted. These standards should be revised after being applied in the future.

    The Sustainable Development Goals have set an agenda for transformational change in water access, aiming for secure household connections globally. Despite this goal, communal groundwater supplies are likely to remain the main source of improved water supplies for many rural areas in Africa and South Asia for decades to come. Understanding the poor functionality of existing communal supplies remains, therefore, a priority. A critical first step is to establish a sector-wide definition of borehole supply functionality and a standard method of its assessment.

    2014-06-01

    In a risk assessment of cosmetic products, it is necessary to know both qualitative and quantitative compositions. Currently, European Regulation No. 1223/2009 requires the industries to provide ingredient lists for finished cosmetic products but not their concentrations. Ingredient concentrations are available in few bibliographic references but in an incomplete and approximate way. In this study, we propose a method to qualitatively and quantitatively estimate the composition of a cosmetic product. This method has the advantages of being applicable to all cosmetic products and supplying concentration data for all ingredients. The results obtained seem quite fair compared to literature data. Applied to nail polish as an example, this method can be used to assess exposure per ingredient according to the Monte Carlo probabilistic method. It should be promising to assess the consumer risk to cosmetic product compositions. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The aim of this article is to report on current provider evidence-based assessment and treatment practices for older adults with cancer in community-based hospice settings. Using the Cancer Pain Practices Index (CPPI), a tool developed by the researchers to measure evidence-based pain management practices, patients received an average of 32% of the those key evidence-based practices (EBPs) that were applicable to their situation. When examining individual practices, the majority of patients had their pain assessed at admission using a valid pain scale (69.7%) and had primary components of a comprehensive assessment completed at admission (52.7%); most patients with admission reports of pain had an order for pain medication (83.5%). However, data revealed a number of practice gaps including: additional components of a comprehensive assessment completed within 48 hours of admission (0%); review of the Pain Treatment Plan at each reassessment (35.7%); reassessment of moderate or greater pain (5.3%); consecutive pain reports of 5 or greater followed by pain medication increases (15.8%); monitoring of analgesic- induced side effects (19.3%); initiation of a bowel regimen for patients with an opioid order (32.3%); and documentation of both non-pharmacological therapies (22.5%) and written pain management plans (0.6%). Findings highlight positive EBPs and areas for improving the translation of EBPs into practice. Data suggest that cancer pain is not being documented as consistently assessed, reassessed or treated in a manner consistent with current EBP recommendations for older adults with cancer in community-based hospices.

    1999-11-01

    A network of national and international guidelines and directives developed in the last few decades by various bodies will lead to a new concept of total quality for medical laboratory services comprising legislative regulations on national and international levels, standardizations backed up by legislation and recommendations of professional societies. One example is the IVD Directive of the European Community. It will not only stimulate accreditation in the field of laboratory medicine, but also necessitate numerous standardization activities which are presently co-ordinated by the European Committee for Standardization (CEN). Another standardization example is the development of quality management systems, mainly by ISO. The ISO 9000 series has become the most successful family of standards world-wide. Meanwhile, specific standards for the needs of laboratories (ISO 17025), and in particular of medical laboratories (ISO 15189), are being worked out. A new trend to develop quality management systems towards total quality management systems can be observed including additional aspects such as economic and quality interests of society, customers and owners of laboratories. The goal of all activities is to create a network of confidence which provides some guarantee to the clients, i.e. the physicians and their patients, that they will receive a high-quality medical laboratory service.

    To develop standardized texts in Brazilian Portuguese to assess reading speed and compare performances among four European languages. 10 texts were designed by a linguistic expert at the level of a sixth grade reading material (reading ages 10-12 years) and were matched for length and syntactic complexity, according to the syntactic prediction locality theory of Gibson. Normally sighted native speaking volunteers aged 18-35 years read each text aloud at random. The reading speed was on average 1100 +/- 167 (standard deviation) characters per minute. Only small differences were found between the measured reading speeds of the 10 texts, and these differences were not statistically significant in groups of at least 6 texts. The mean reading speed in age-matched volunteers in Finnish was: 1263 +/- 142; French: 1214 +/- 152; English: 1234 +/- 147; and German: 1126 +/- 105. The authors developed a set of standardized, homogeneous, and comparable texts in Brazilian Portuguese. These texts will be a valuable tool to measure reading speed for repeated measurements and in international studies in the field of reading and low vision research.

    This study provided new information on sediment mercury (Hg) and monomethylmercury (MMHg) content and chemistry. The current inventory of Hg in East Fork Poplar Creek (EFPC) bed sediments was estimated to be 334 kg, which represents a ~67% decrease relative to the initial investigations in 1984. MMHg sediment inventory was estimated to be 44.1 g, lower but roughly similar to past estimates. The results support the relevance and potential impacts of other active and planned investigations within the Mercury Remediation Technology Development for Lower East Fork Poplar Creek project (e.g., assessment and control of bank soil inputs, sorbents for Hg and MMHg removal, re-introduction of freshwater clams to EFPC), and identify gaps in current understanding that represent opportunities to understand controlling variables that may inform future technology development studies.

    Workers exposed to hand-arm vibration are at risk of developing the neurological abnormalities of hand-arm vibration syndrome (HAVS). The Stockholm classification of the neurological component of HAVS is based on history and physical examination. There is a need to determine the association between neurological tests and the Stockholm scale. The main objective of this study was to compare the Stockholm neurological scale and the results of current perception threshold (CPT) tests and nerve conduction studies (NCS). Detailed physical examinations were done on 162 subjects referred for HAVS assessment at a specialist occupational health clinic. All subjects had NCS and measurement of CPT. The Stockholm neurological classification was carried out blinded to the results of these neurological tests and compared to the test results. The nerve conduction results indicated that median and ulnar neuropathies proximal to the hand are common in workers being assessed for HAVS. Digital sensory neuropathy was found in only one worker. Neither the nerve conduction results nor the current perception results had a strong association with the Stockholm neurological scale. Exposure to vibration in total hours was the main variable associated with the Stockholm neurological scale [right hand: OR 1.30, 95% CI (1.10-1.54); left hand: OR 1.18, 95% CI (1.0-1.39)]. Workers being assessed for HAVS should have nerve conduction testing to detect neuropathies proximal to the hand. Quantitative sensory tests such as current perception measurement are insufficient for diagnostic purposes but may have a role in screening workers exposed to vibration.

    To compare the validity of the Montreal Cognitive Assessment (MoCA) with the criterion standard of standardized neuropsychological testing and to compare the convergent validity of the MoCA with that of existing screening tools and global measures of cognition. Cross-sectional observational study. Tertiary care hospital-based cognitive neurology subspecialty clinic. A convenience sample of 107 individuals with mild Alzheimer's disease (AD, n=75) or mild cognitive impairment (MCI, n=32) from the Sunnybrook Dementia Study. In addition to the MoCA, all participants completed the Mini-Mental State Examination (MMSE), the Mattis Dementia Rating Scale (DRS), and detailed neuropsychological testing. Convergent validity was supported, with MoCA scores correlating well with the MMSE (correlation coefficient (r)=0.66, Ptests and, in the case of memory (area under the receiver operating characteristic curve (AUC)=0.86), executive (AUC=0.79), and visuospatial function (AUC=0.79), being reasonably sensitive to impairment in those domains. The MoCA is a valid assessment of cognition that shows good agreement with existing screening tools and global measures (convergent validity) and was superior to the MMSE in this regard. The MoCA domain-specific subscores align with performance on more-detailed neuropsychological tests, suggesting not only good criterion validity for the MoCA, but also that it may be useful in guiding further neuropsychological testing. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

    2015-01-01

    Full Text Available Recently increasing interest in multimedia services leads to requirements for quality assessment, especially in the video domain. There are many factors that influence the video quality. Compression technology and transmission link imperfection can be considered as the main ones. This paper deals with the assessment of the impact of H.265/HEVC compression standard on the video quality using subjective metrics. The evaluation is done for two types of sequences with Full HD resolution depending on content. The paper is divided as follows. In the first part of the article, a short characteristic of the H.265/HEVC compression standard is written. In the second part, the subjective video quality methods used in our experiments are described. The last part of this article deals with the measurements and experimental results. They showed that quality of sequences coded between 5 and 7 Mbps is for observers sufficient, so there is no need for providers to use higher bitrates in streaming than this threshold. These results are part of a new model that is still being created and will be used for predicting the video quality in networks based on IP.

    Purpose: Osteogenesis imperfecta (OI) is a rare hereditary disease leading to multiple bone deformities and fractures. In the absence of causal therapy, a symptomatic approach is based on treatment with bisphosphonates and physiotherapy. The clinical and radiological manifestations vary. Therefore, standardization and quantification for an objective comparison, especially during therapy, are required. In this paper, radiological changes of the spine are quantified according to their clinical relevance to define a scoring system that transfers the morphological changes into a single value representing the severity of the disease. Materials and Methods: 268 lateral spine X-rays of 95 patients with OI (median age 5.6 years) were assessed. The findings were classified based on their clinical relevance. Results: The three criteria, vertebral compression, thoracolumbar kyphosis and deformity type, were quantified in a new grading system. Based on this, a 'severity classification' (1 to 5) was defined with implications for diagnostics and treatment. A mathematical formula that takes into account the three criteria and their correlations to clinical relevance, resulting in a 'severity score', was developed. Conclusion: 'Severity classification' and 'severity score' introduce a new concept for a standardized evaluation of spine X-rays in patients with OI. For both scientific and routine purposes, it provides the user with a simple and easy-to-handle tool for assessing and comparing different stages of severity prior to and during therapy with detailed accuracy.

    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.

    In the present study, existing regulatory frameworks and test systems for assessing potential endocrine active chemicals are described, and associated challenges are discussed, along with proposed approaches to address these challenges. Regulatory frameworks vary somewhat across geographies, but all basically evaluate whether a chemical possesses endocrine activity and whether this activity can result in adverse outcomes either to humans or to the environment. Current test systems include in silico, in vitro, and in vivo techniques focused on detecting potential endocrine activity, and in vivo tests that collect apical data to detect possible adverse effects. These test systems are currently designed to robustly assess endocrine activity and/or adverse effects in the estrogen, androgen, and thyroid hormone signaling pathways; however, there are some limitations of current test systems for evaluating endocrine hazard and risk. These limitations include a lack of certainty regarding: 1) adequately sensitive species and life stages; 2) mechanistic endpoints that are diagnostic for endocrine pathways of concern; and 3) the linkage between mechanistic responses and apical, adverse outcomes. Furthermore, some existing test methods are resource intensive with regard to time, cost, and use of animals. However, based on recent experiences, there are opportunities to improve approaches to and guidance for existing test methods and to reduce uncertainty. For example, in vitro high-throughput screening could be used to prioritize chemicals for testing and provide insights as to the most appropriate assays for characterizing hazard and risk. Other recommendations include adding endpoints for elucidating connections between mechanistic effects and adverse outcomes, identifying potentially sensitive taxa for which test methods currently do not exist, and addressing key endocrine pathways of possible concern in addition to those associated with estrogen, androgen, and thyroid

    Full Text Available One of the critical issues in managing information within an organization is to ensure that proper controls exist and are applied in allowing people access to information. Passwords are used extensively as the main control mechanism to identify users wanting access to systems, applications, data files, network servers or personal information. In this article, the issues involved in selecting and using passwords are discussed and the current practices employed by users in creating and storing passwords to gain access to sensitive information are assessed. The results of this survey conclude that information managers cannot rely only on users to employ proper password control in order to protect sensitive information.

    A measure of the efficiency in transforming energy input into transport work is defined and applied to road vehicles as well as to sea, air and rail vehicles for passenger or freight transportation. The insight obtained with this measure is compared with the results of applying the conventional measure of kilometres per unit of energy for current fleets of vehicles. Then, simulation methods are used to assess the performance of fuel cell vehicles, electric vehicles and hybrids between the two. The latter are found to provide an optimum performance for a small, efficient passenger car. (author)

    The right ventricle has unique structural and functional characteristics. It is now well recognized that the so-called forgotten ventricle is a key player in cardiovascular physiology. Furthermore, there is accumulating evidence that demonstrates right ventricular dysfunction as an important marker of morbidity and mortality in several commonly encountered clinical situations such as heart failure, pulmonary hypertension, pulmonary embolism, right ventricular myocardial infarction, and adult congenital heart disease. In contrast to the left ventricle, echocardiographic assessment of right ventricular function is more challenging as volume estimations are not possible without the use of three-dimensional (3D) echocardiography. Guidelines on chamber quantification provide a standardized approach to assessment of the right ventricle. The technique and limitations of each of the parameters for RV size and function need to be fully understood. In this era of multimodality imaging, echocardiography continues to remain a useful tool for the initial assessment and follow-up of patients with right heart pathology. Several novel approaches such as 3D and strain imaging of the right ventricle have expanded the usefulness of this indispensable modality. © 2017, Wiley Periodicals, Inc.

    With advances in joint preservation surgery that are intended to alter the course of osteoarthritis by early intervention, accurate and reliable assessment of the cartilage status is critical. Biochemically sensitive MRI techniques can add robust biomarkers for disease onset and progression, and therefore, could be meaningful assessment tools for the diagnosis and follow-up of cartilage abnormalities. T2* mapping could be a good alternative because it would combine the benefits of biochemical cartilage evaluation with remarkable features including short imaging time and the ability of high-resolution three-dimensional cartilage evaluation - without the need for contrast media administration or special hardware. Several in vitro and in vivo studies, which have elaborated on the potential of cartilage T2* assessment in various cartilage disease patterns and grades of degeneration, have been reported. However, much remains to be understood and certain unresolved questions have become apparent with these studies that are crucial to the further application of this technique. This review summarizes the principles of the technique and current applications of T2* mapping for articular cartilage assessment. Limitations of recent studies are discussed and the potential implications for patient care are presented. (orig.)

    Fibrosis, a common pathogenic pathway of chronic liver disease (CLD), has long been indicated to be significantly and most importantly associated with severe prognosis. Nowadays, with remarkable advances in understanding and/or treatment of major CLDs such as hepatitis C, B, and nonalcoholic fatty liver disease, there is an unprecedented requirement for the diagnosis and assessment of liver fibrosis or cirrhosis in various clinical settings. Among the available approaches, liver biopsy remains the one which possibly provides the most direct and reliable information regarding fibrosis patterns and changes in the parenchyma at different clinical stages and with different etiologies. Thus, many endeavors have been undertaken for developing methodologies based on the strategy of quantitation for the invasive assessment. Here, we analyze the impact of fibrosis assessment on the CLD patient care based on the data of recent clinical studies. We discuss and update the current invasive tools regarding their technological features and potentials for the particular clinical applications. Furthermore, we propose the potential resolutions with application of quantitative invasive tools for some major issues in fibrosis assessment, which appear to be obstacles against the nowadays rapid progress in CLD medicine.

    Considerable effort in the astronomy education research over the past several years has focused on developing assessment tools in the form of multiple-choice conceptual diagnostics and content knowledge surveys. This has been critically important in advancing astronomy as a sub-discipline of physics education research, allowing researchers to establish the initial knowledge state of students as well as to attempt to measure some of the impacts of innovative instructional interventions. Before now, few of the existing instruments were constructed upon a solid list of clearly articulated and widely agreed upon learning objectives. Moving beyond the 10-year old Astronomy Diagnostics Test, we have developed and validated a new assessment instrument that is tightly aligned to the consensus learning goals stated by the American Astronomical Society - Chair's Conference on ASTRO 101, the American Association of the Advancement of Science's Project 2061 Benchmarks, and the National Research Council's National Science Education Standards. Researchers from the Cognition in Astronomy, Physics and Earth sciences Research (CAPER) Team at the University of Wyoming's Science and Math Teaching Center (UWYO SMTC) designed a criterion-referenced assessment tool, called the Test Of Astronomy STandards (TOAST). Through iterative development, this multiple-choice instrument has a high degree of reliability and validity for instructors and researchers needing information on students’ initial knowledge state at the beginning of a course and can be used, in aggregate, to help measure the impact of course-length duration instructional strategies for undergraduate science survey courses with learning goals tightly aligned to the consensus goals of the astronomy education community.

    SUMMARY Background Existing studies on quality of tuberculosis care mostly reflect knowledge, not actual practice. Methods We conducted a validation study on the use of standardized patients (SPs) for assessing quality of TB care. Four cases, two for presumed TB and one each for confirmed TB and suspected MDR-TB, were presented by 17 SPs, with 250 SP interactions among 100 consenting providers in Delhi, including qualified (29%), alternative medicine (40%) and informal providers (31%). Validation criteria were: (1) negligible risk and ability to avoid adverse events for providers and SPs; (2) low detection rates of SPs by providers, and (3) data accuracy across SPs and audio verification of SP recall. We used medical vignettes to assess provider knowledge for presumed TB. Correct case management was benchmarked using Standards for TB Care in India (STCI). Findings SPs were deployed with low detection rates (4.7% of 232 interactions), high correlation of recall with audio recordings (r=0.63; 95% CI: 0.53 – 0.79), and no safety concerns. Average consultation length was 6 minutes with 6.2 questions/exams completed, representing 35% (95% confidence interval [CI]: 33%–38%) of essential checklist items. Across all cases, only 52 of 250 (21%; 95% CI: 16%–26%) were correctly managed. Correct management was higher among MBBS doctors (adjusted OR=2.41, 95% CI: 1.17–4.93) as compared to all others. Provider knowledge in the vignettes was markedly more consistent with STCI than their practice. Interpretation The SP methodology can be successfully implemented to assess TB care. Our data suggest a big gap between provider knowledge and practice. PMID:26268690

    Extinction rates in the Anthropocene are three orders of magnitude higher than background and disproportionately occur in the tropics, home of half the world's species. Despite global efforts to combat tropical species extinctions, lack of high-quality, objective information on tropical biodiversity has hampered quantitative evaluation of conservation strategies. In particular, the scarcity of population-level monitoring in tropical forests has stymied assessment of biodiversity outcomes, such as the status and trends of animal populations in protected areas. Here, we evaluate occupancy trends for 511 populations of terrestrial mammals and birds, representing 244 species from 15 tropical forest protected areas on three continents. For the first time to our knowledge, we use annual surveys from tropical forests worldwide that employ a standardized camera trapping protocol, and we compute data analytics that correct for imperfect detection. We found that occupancy declined in 22%, increased in 17%, and exhibited no change in 22% of populations during the last 3-8 years, while 39% of populations were detected too infrequently to assess occupancy changes. Despite extensive variability in occupancy trends, these 15 tropical protected areas have not exhibited systematic declines in biodiversity (i.e., occupancy, richness, or evenness) at the community level. Our results differ from reports of widespread biodiversity declines based on aggregated secondary data and expert opinion and suggest less extreme deterioration in tropical forest protected areas. We simultaneously fill an important conservation data gap and demonstrate the value of large-scale monitoring infrastructure and powerful analytics, which can be scaled to incorporate additional sites, ecosystems, and monitoring methods. In an era of catastrophic biodiversity loss, robust indicators produced from standardized monitoring infrastructure are critical to accurately assess population outcomes and identify

    The impact of opioid-related sedation progressing to respiratory depression in the Post Anesthesia Care Unit (PACU) can be extensive; however, there is a paucity of research on the subject of standardized assessment tools to prevent adverse events. The purposes of this study were: (1) to measure the efficacy of a standardized method of assessing sedation and administering opioids for pain management via the Pasero Opioid-Induced Sedation Scale (POSS) with interventions in the PACU; (2) to increase PACU nurses' confidence in assessing sedation associated with opioid administration for pain management and in the quality of care provided in their clinical area; and (3) to facilitate PACU and postoperative clinical unit nurses' communications during patient handoffs regarding safe opioid administration. A quasi-experimental design was used to evaluate the POSS protocol. Two PACUs and six nursing units receiving postsurgical patients in a Midwestern inner-city hospital served as the setting for this research. Medical records were surveyed for outcome data to evaluate the efficacy of the care protocol in two patient cohorts before and after implementation of the POSS protocol. Nurses completed a written survey to identify changes in satisfaction with nurse-to-nurse communication, perceptions of quality of care, and confidence with opioid administration. The final sample included 842 PACU patients and 67 nurses from the PACU and clinical units. The intervention did not significantly change PACU length of stay or amount of administered opioids and patients were noted to be more alert at time of discharge from the PACU. Nurses reported increased perceptions of quality of care and confidence in opioid administration. The findings from this study support the use of the POSS Scale with interventions in the PACU care protocols. Copyright © 2014 American Society for Pain Management Nursing. Published by Elsevier Inc.

    The evaluation of the exposure from mobile communication devices requires consideration of electromagnetic fields (EMFs) over a broad frequency range from dc to GHz. Mobile phones in operation have prominent spectral components in the low-frequency (LF) and radio-frequency (RF) ranges. While the exposure to RF fields from mobile phones has been comprehensively assessed in the past, the LF fields have received much less attention. In this study, LF fields from mobile phones are assessed experimentally and numerically for the global system for mobile (GSM) and universal mobile telecommunications system (UMTS) communication systems and conclusions about the global (LF and RF) EMF exposure from both systems are drawn. From the measurements of the time-domain magnetic fields, it was found that the contribution from the audio signal at a normal speech level, i.e., -16 dBm0, is the same order of magnitude as the fields induced by the current bursts generated from the implementation of the GSM communication system at maximum RF output level. The B-field induced by currents in phones using the UMTS is two orders of magnitude lower than that induced by GSM. Knowing that the RF exposure from the UMTS is also two orders of magnitude lower than from GSM, it is now possible to state that there is an overall reduction of the exposure from this communication system.

    Intrroduction: Incorrect eating habits are a significant risk factor for breast tumours. An appropriate diet is a vital part in the treatment of such a disorder. The aim of the study was to assess current eating habits in women diagnosed with breast tumours and the changes introduced after diagnosis. The survey was conducted among 200 women aged 59±11.2 with a diagnosed breast tumour. An original survey questionnaire was used to assess the respondents' dietary habits. Questions pertained to the frequency of consumption of certain food groups, changes in diet since the moment of diagnosis and sources of knowledge about nutrition. A number of current incorrect eating habits became apparent (namely, low frequency of eating wholemeal products, legumes, fish, vegetables, fruit and high frequency of eating sweets), as well as many beneficial changes introduced after the diagnosis (more frequent consumption of wholemeal products, poultry, vegetables and fruit and lower frequency of consumption of red meat, meat preserves, sweets, sweetened drinks and alcohol), with no difference in age, education or time elapsed since the diagnosis. Less than one third of respondents have received nutrition advice after their diagnosis. In spite of the beneficial changes in dietary habits there is a need for widely available, reliable nutrition education amongst all women diagnosed with a breast tumour.

    There is a pressing need for drug development in pediatric Crohn disease (CD). Our aim was to provide strategic approaches toward harmonization of current thinking about clinical outcome assessments (COAs) and biomarkers to facilitate drug development in pediatric CD. Scientists from the United States Food and Drug Administration, European Medicines Agency, Health Canada, and the Pharmaceuticals and Medical Devices Agency of Japan had monthly teleconferences from January 2014 through May 2015. A literature review was conducted to assess the measurement properties of all existing COA tools and to evaluate the current landscape of biomarkers used in pediatric CD. Based on the findings of literature review, we reached the consensus on the strategic approaches for evaluating outcomes in pediatric CD trials. The pediatric Crohn's Disease Activity Index, Crohn's Disease Activity Index, and Harvey-Bradshaw's index were used in pediatric CD clinical studies. But they lack adequate measurement properties (validity, reliability, and ability to detect change of the treatment) that are required to support approval of products intended to treat pediatric CD. Biomarkers (ie, fecal lactoferrin, osteoprotegerin, and calprotectin) have shown some promise for their potential as noninvasive surrogate endpoints in CD. Lack of well-defined and reliable COAs presents a hurdle for global drug development in pediatric CD. It is essential to develop well-defined and reliable COAs that can measure meaningful clinical benefit for patients in terms of how they feel, function, and survive. Development of noninvasive biomarkers as reliable surrogate endpoints needs to be further explored.

    As planning for the next generation of high contrast imaging instruments (e.g., WFIRST, HabEx, and LUVOIR, TMT-PFI, EELT-EPICS) matures and second-generation ground-based extreme adaptive optics facilities (e.g., VLT-SPHERE, Gemini-GPI) finish their principal surveys, it is imperative that the performance of different designs, post-processing algorithms, observing strategies, and survey results be compared in a consistent, statistically robust framework. In this paper, we argue that the current industry standard for such comparisons—the contrast curve—falls short of this mandate. We propose a new figure of merit, the “performance map,” that incorporates three fundamental concepts in signal detection theory: the true positive fraction, the false positive fraction, and the detection threshold. By supplying a theoretical basis and recipe for generating the performance map, we hope to encourage the widespread adoption of this new metric across subfields in exoplanet imaging.

    The present paper deals with the quality assessment of PLC channel which is a part of fault-tolerant self-organizing heterogeneous communication system. The PLC implementation allows to reduce exploitation costs when constructing new info-communication networks. PLC is used for transmitting information between various devices in alternating current mains. There exist different approaches to transfer information over power lines. Their differences resulted from the requirements of typical apps which use PLC as a data transmission channel. In the process of research described in this paper, the simulation of a signal in AC mains with regard to different kinds of noise caused by power line loads was performed.

    Abstract Background A number of recent developments in medical and nursing education have highlighted the importance of communication and consultation skills (CCS). Although such skills are taught in all medical and nursing undergraduate curriculums, there is no comprehensive screening or assessment programme of CCS using professionally trained Standardized Patients Educators (SPE\\'s) in Ireland. This study was designed to test the content, process and acceptability of a screening programme in CCS with Irish medical and nursing students using trained SPE\\'s and a previously validated global rating scale for CCS. Methods Eight tutors from the Schools of Nursing and Medicine at University College Cork were trained in the use of a validated communication skills and attitudes holistic assessment tool. A total of forty six medical students (Year 2 of 5) and sixty four nursing students (Year 2\\/3 of 4) were selected to under go individual CCS assessment by the tutors via an SPE led scenario. Immediate formative feedback was provided by the SPE\\'s for the students. Students who did not pass the assessment were referred for remediation CCS learning. Results Almost three quarters of medical students (33\\/46; 72%) and 81% of nursing students (56\\/64) passed the CCS assessment in both communication and attitudes categories. All nursing students had English as their first language. Nine of thirteen medical students referred for enhanced learning in CCS did not have English as their first language. Conclusions A significant proportion of both medical and nursing students required referral for enhanced training in CCS. Medical students requiring enhanced training were more likely not to have English as a first language.

    Telemedicine has been used for remote management of many medical problems. Given the ever-expanding demands to provide increasing service with increasingly limited resources, quality care and practice efficiency can be enhanced by telemedicine. This study was undertaken to explore the reliability of wound assessment using computer-transmitted digital imagery compared with a traditional bedside evaluation and also to assess its potential role in healthcare delivery. In the hospital setting, rounding vascular surgeons and a surgical resident evaluated the wounds on the service. A digital photograph was obtained with a 3.3 megapixel camera, and a wound-assessment tool was completed. A plastic surgery attending then reviewed the images at a later date and completed the same data tool. Wounds were rated for eschar, exposed bone, cellulitis, purulence, swelling, granulation tissue, granulation color, and depth using a standardized data collection tool. kappa statistics were computed for all variables, between raters. There were 2 phases of the study. In both phases, there was 100% agreement by the rounding physicians that the digital image was representative of the wound. Phase 1 agreement between evaluators was moderate to almost perfect, as demonstrated by kappa values (range, 0.50-0.87). In phase 2, all variable kappa values were rated as almost perfect, except the ability to evaluate depth of the wound to the millimeter, which was rated as substantial. The ability to accurately evaluate a wound on the basis of a digital image is possible. However, it requires training of participants and is facilitated by use of an assessment tool. With these caveats, evaluation of wounds using digital images is equivalent to bedside examination. This technology can improve practice efficiency, provide needed expertise at remote sites, and is an acceptable alternative method of wound assessment.

    Full Text Available OBJECTIVES: To describe the development, validation and inter-rater reliability of an instrument to measure the quality of patient decision support technologies (decision aids. DESIGN: Scale development study, involving construct, item and scale development, validation and reliability testing. SETTING: There has been increasing use of decision support technologies--adjuncts to the discussions clinicians have with patients about difficult decisions. A global interest in developing these interventions exists among both for-profit and not-for-profit organisations. It is therefore essential to have internationally accepted standards to assess the quality of their development, process, content, potential bias and method of field testing and evaluation. METHODS: Scale development study, involving construct, item and scale development, validation and reliability testing. PARTICIPANTS: Twenty-five researcher-members of the International Patient Decision Aid Standards Collaboration worked together to develop the instrument (IPDASi. In the fourth Stage (reliability study, eight raters assessed thirty randomly selected decision support technologies. RESULTS: IPDASi measures quality in 10 dimensions, using 47 items, and provides an overall quality score (scaled from 0 to 100 for each intervention. Overall IPDASi scores ranged from 33 to 82 across the decision support technologies sampled (n = 30, enabling discrimination. The inter-rater intraclass correlation for the overall quality score was 0.80. Correlations of dimension scores with the overall score were all positive (0.31 to 0.68. Cronbach's alpha values for the 8 raters ranged from 0.72 to 0.93. Cronbach's alphas based on the dimension means ranged from 0.50 to 0.81, indicating that the dimensions, although well correlated, measure different aspects of decision support technology quality. A short version (19 items was also developed that had very similar mean scores to IPDASi and high correlation

    The ability to perform two tasks simultaneously has become increasingly important as attention-demanding technologies have become more common in daily life. This type of attentional resources allocation is commonly called "divided attention". Because of the importance of divided attention in natural world settings, substantial efforts have been made recently so as to promote an integrated, realistic assessment of functional abilities in dual-task paradigms. In this context, virtual reality methods appear to be a good solution. However to date, there has been little discussion on validity of such methods. Here, we offer a comparative review of conventional tools used to assess divided attention and of the first virtual reality studies (mostly from the field of road and pedestrian safety). The ecological character of virtual environments leads to a better understanding of the influence of dual-task settings and also makes it possible to clarify issues such as the utility of hands-free phones. After discussing the theoretical and clinical contributions of these studies, we discuss the limits of virtual reality assessment, focusing in particular: (i) on the challenges associated with lack of familiarity with new technological devices; (ii) on the validity of the ecological character of virtual environments; and (iii) on the question of whether the results obtained in a specific context can be generalized to all dual-task situations typical of daily life. To overcome the limitations associated with virtual reality, we propose: (i) to include a standardized familiarization phase in assessment protocols so as to limit the interference caused by the use of new technologies; (ii) to systematically compare virtual reality performance with conventional tests or real-life tests; and (iii) to design dual-task scenarios that are independent from the patient's expertise on one of the two tasks. We conclude that virtual reality appears to constitute a useful tool when used in

    The NASA Earth Venture Program has led to a dramatic increase in airborne observations, requiring updated data management practices with clearly defined data standards and protocols for metadata. While the current data management practices demonstrate some success in serving airborne science team data user needs, existing metadata models and standards such as NASA's Unified Metadata Model (UMM) for Collections (UMM-C) present challenges with respect to accommodating certain features of airborne science metadata. UMM is the model implemented in the Common Metadata Repository (CMR), which catalogs all metadata records for NASA's Earth Observing System Data and Information System (EOSDIS). One example of these challenges is with representation of spatial and temporal metadata. In addition, many airborne missions target a particular geophysical event, such as a developing hurricane. In such cases, metadata about the event is also important for understanding the data. While coverage of satellite missions is highly predictable based on orbit characteristics, airborne missions feature complicated flight patterns where measurements can be spatially and temporally discontinuous. Therefore, existing metadata models will need to be expanded for airborne measurements and sampling strategies. An Airborne Metadata Working Group was established under the auspices of NASA's Earth Science Data Systems Working Group (ESDSWG) to identify specific features of airborne metadata that can not be currently represented in the UMM and to develop new recommendations. The group includes representation from airborne data users and providers. This presentation will discuss the challenges and recommendations in an effort to demonstrate how airborne metadata curation/management can be improved to streamline data ingest and discoverability to a broader user community.

    Health professions education is gradually moving away from the more traditional approaches to new innovative ways of training aimed at producing professionals with the necessary competencies to address the community health needs. In response to these emerging trends, Medical Education for Equitable Services to All Ugandans (MESAU), a consortium of Ugandan medical schools developed key competencies desirable of graduates and successfully implemented Competency Based Education (CBE) for undergraduate medical students. To examine the current situation and establish whether assessment methods of the competencies are standardized across MESAU schools as well as establish the challenges, opportunities and lessons learned from the MESAU consortium. It was a cross-sectional descriptive study involving faculty of the medical schools in Uganda. Data was collected using focus group discussions and document reviews. Findings were presented in form of themes. Although the MESAU schools have implemented the developed competencies within their curricular, the assessment methods are still not standardized with each institution having its own assessment procedures. Lack of knowledge and skills regarding assessment of the competencies was evident amongst the faculty. The fear for change amongst lecturers was also noted as a major challenge. However, the institutional collaboration created while developing competencies was identified as key strength. Findings demonstrated that despite having common competencies, there is no standardized assessment blue print applicable to all MESAU schools. Continued collaboration and faculty development in assessment is strongly recommended.

    To assess patient adherence among pregnant women infected with Chlamydia trachomatis given a self-administered, 10-day course of erythromycin prescribed as 500-mg tablets to be taken four times a day for the full 10-day period of treatment. Study participants (n = 30) were given the standard, 10-day supply of 500-mg tablets of erythromycin and instructed to take one tablet four times daily for 10 days. Patients were blinded to the fact that the Medication Event Monitoring System was being used and that their adherence to this course of drug therapy was being monitored. A 100% cure rate was achieved. The average percentage of therapeutic coverage actually achieved by the study participants declined with the length of erythromycin therapy. Further, as the duration of treatment increased, the longest interval between two successive doses of erythromycin also increased. This study demonstrated the importance of assessing both the quantitative and temporal aspects of self-administered oral medication when assessing patient adherence. Moreover, since the length of the course of antibiotic therapy was shown to affect patient adherence, coupled with the 100% cure rate we observed, future research geared toward maximizing adherence while minimizing duration of treatment seems warranted.

  11. CRM Assessment: Determining the Generalization of Rater Calibration Training. Summary of Research Report: Gold Standards Training

    The extent to which pilot instructors are trained to assess crew resource management (CRM) skills accurately during Line-Oriented Flight Training (LOFT) and Line Operational Evaluation (LOE) scenarios is critical. Pilot instructors must make accurate performance ratings to ensure that proper feedback is provided to flight crews and appropriate decisions are made regarding certification to fly the line. Furthermore, the Federal Aviation Administration's (FAA) Advanced Qualification Program (AQP) requires that instructors be trained explicitly to evaluate both technical and CRM performance (i.e., rater training) and also requires that proficiency and standardization of instructors be verified periodically. To address the critical need for effective pilot instructor training, the American Institutes for Research (AIR) reviewed the relevant research on rater training and, based on "best practices" from this research, developed a new strategy for training pilot instructors to assess crew performance. In addition, we explored new statistical techniques for assessing the effectiveness of pilot instructor training. The results of our research are briefly summarized below. This summary is followed by abstracts of articles and book chapters published under this grant.

  12. Best Practices in Physics Program Assessment: Should APS Provide Accreditation Standards for Physics?

    Science.gov (United States)

    Hodapp, Theodore

    The Phys21 report, ``Preparing Physics Students for 21st Century Careers,'' provides guidance for physics programs to improve their degree programs to make them more relevant for student career choices. Undertaking such changes and assessing impact varies widely by institution, with many departments inventing assessments with each periodic departmental or programmatic review. American Physical Society has embarked on a process to integrate information from Phys21, the results of other national studies, and educational research outcomes to generate a best-practices guide to help physics departments conduct program review, assessment, and improvement. It is anticipated that departments will be able to use this document to help with their role in university-level accreditation, and in making the case for improvements to departmental programs. Accreditation of physics programs could stem from such a document, and I will discuss some of the thinking of the APS Committee on Education in creating this guide, and how they are advising APS to move forward in the higher education landscape that is increasingly subject to standards-based evaluations. I will describe plans for the design, review, and dissemination of this guide, and how faculty can provide input into its development.

  13. Construction and assessment of hierarchical edge elements for three-dimensional computations of eddy currents

    1997-12-31

    This thesis considers the feasibility of doing calculations to optimize electrical machines without the need to build expensive prototypes. It deals with the construction and assessment of new, hierarchical, hexahedral edge elements for three-dimensional computations of eddy currents with the electric vector potential formulation. The new elements, five in all, gave up to second-order approximations for both the magnetic field and the current density. Theoretical arguments showed these elements to be more economical for a given polynomial order of the approximated fields than the serendipity family of nodal elements. Further it was pointed out how the support of a source field computed by using edge elements could be made very small provided that a proper spanning tree was used in the edge element mesh. This was exploited for the voltage forcing technique, where source fields were used as basis functions, with unknown total currents in voltage forced conductors as degrees of freedom. The practical assessment of the edge elements proved the accuracy to improve with increasing polynomial order, both for local and global quantities. The most economical element was, however, one giving only complete first-order approximations for both fields. Further, the edge elements turned out to be better than the nodal elements also in practice. For the voltage forcing technique, source field basis functions which had small support, resulted in large reduction of the CPU-time for solving the main equation system, compared to source fields which had large support. The new elements can be used in a p-type adaptive scheme, and they should also be applicable for other tangentially continuous field problems. 67 refs., 34 figs., 10 tabs.

    2017-12-07

    The first standards for chemical protective clothing (CPC) emerged mid to late 1980's and have evolved since as most standards are revisited every 5 yr. Over the past years, we have also seen a strengthening of the chemical and worker protection legislation around the globe (various forms of REACH) but also protection of workers. The most prevalent standards originate under the auspices of the International Standards Organisation (ISO), European Committee for Standardisation (CEN) or under various US standards organisations (e.g. NFPA, ASTM). Protective clothing against hazardous materials is required in many of the professional and non-professional activities of everyday life. Effective and adequate protection is important in many scenarios from household (e.g. cleaning agents, peroxides, acids and bases, paints), to agricultural (e.g. fuel, pesticides), to medical (e.g. pharmaceuticals and active ingredients), to industrial production (e.g. petro-chemicals, chemicals, paints, adhesive and coatings) but also manufacturing of many products (e.g. light bulbs, cars, semi-conductors), during various emergency activities (e.g. boat, rail or road accidents as well as fire-fighting in an urban and industrial setting), and finally, military operations or response to incidents of terrorism. Nevertheless, CPC must remain the last line of defence whenever possible through a preference for less hazardous chemicals, less dangerous processes and handling operations, and by engineering controls to reduce and minimise human contact with the chemicals. This article provides information about the selection, use, care and maintenance (SUCAM) of protective clothing against chemical and microbiological hazards.

    2013-10-01

    Novel mobile assessment and intervention capabilities are changing the face of physical activity (PA) research. A comprehensive systematic review of how mobile technology has been used for measuring PA and promoting PA behavior change is needed. Article collection was conducted using six databases from February to June 2012 with search terms related to mobile technology and PA. Articles that described the use of mobile technologies for PA assessment, sedentary behavior assessment, and/or interventions for PA behavior change were included. Articles were screened for inclusion and study information was extracted. Analyses were conducted from June to September 2012. Mobile phone-based journals and questionnaires, short message service (SMS) prompts, and on-body PA sensing systems were the mobile technologies most utilized. Results indicate that mobile journals and questionnaires are effective PA self-report measurement tools. Intervention studies that reported successful promotion of PA behavior change employed SMS communication, mobile journaling, or both SMS and mobile journaling. mHealth technologies are increasingly being employed to assess and intervene on PA in clinical, epidemiologic, and intervention research. The wide variations in technologies used and outcomes measured limit comparability across studies, and hamper identification of the most promising technologies. Further, the pace of technologic advancement currently outstrips that of scientific inquiry. New adaptive, sequential research designs that take advantage of ongoing technology development are needed. At the same time, scientific norms must shift to accept "smart," adaptive, iterative, evidence-based assessment and intervention technologies that will, by nature, improve during implementation. © 2013 American Journal of Preventive Medicine.

    Managers often nest sections of water bodies together into assessment units (AUs) to monitor and assess water quality criteria. Ideally, AUs represent an extent of waters with similar ecological, watershed, habitat and land-use conditions and no overlapping characteristics with other waters. In the United States, AUs are typically based on political or hydrologic boundaries rather than on ecologically relevant features, so it can be difficult to detect changes in impairment status. Our goals were to evaluate if current AU designation criteria of an impaired water body in southeastern Idaho, USA that, like many U.S. waters, has three-quarters of its mainstem length divided into two AUs. We focused our evaluation in southeastern Idaho's Portneuf River, an impaired river and three-quarters of the river is divided into two AUs. We described biological and environmental conditions at multiple reaches within each AU. We used these data to (1) test if variability at the reach-scale is greater within or among AUs and, (2) to evaluate alternate AU boundaries based on multivariate analyses of reach-scale data. We found that some biological conditions had greater variability within an AU than between AUs. Multivariate analyses identified alternative, 2- and 3-group, AUs that reduced this variability. Our results suggest that the current AU designations in the mainstem Portneuf River contain ecologically distinct sections of river and that the existing AU boundaries should be reconsidered in light of the ecological conditions measured at the reach scale. Variation in biological integrity within designated AUs may complicate water quality and biological assessments, influence management decisions or affect where monitoring or mitigation resources are directed.

    2013-09-15

    Increasing energy consumption and depleting reserves of fossil fuels have resulted in growing interest in alternative renewable energy from the ocean. Ocean currents are an alternative source of clean energy due to their inherent reliability, persistence and sustainability. General ocean circulations exist in the form of large rotating ocean gyres, and feature extremely rapid current flow in the western boundaries due to the Coriolis Effect. The Gulf Stream system is formed by the western boundary current of the North Atlantic Ocean that flows along the east coastline of the United States, and therefore is of particular interest as a potential energy resource for the United States. This project created a national database of ocean current energy resources to help advance awareness and market penetration in ocean current energy resource assessment. The database, consisting of joint velocity magnitude and direction probability histograms, was created from data created by seven years of numerical model simulations. The accuracy of the database was evaluated by ORNL?s independent validation effort documented in a separate report. Estimates of the total theoretical power resource contained in the ocean currents were calculated utilizing two separate approaches. Firstly, the theoretical energy balance in the Gulf Stream system was examined using the two-dimensional ocean circulation equations based on the assumptions of the Stommel model for subtropical gyres with the quasi-geostrophic balance between pressure gradient, Coriolis force, wind stress and friction driving the circulation. Parameters including water depth, natural dissipation rate and wind stress are calibrated in the model so that the model can reproduce reasonable flow properties including volume flux and energy flux. To represent flow dissipation due to turbines additional turbine drag coefficient is formulated and included in the model. Secondly, to determine the reasonableness of the total power

    Cystic fibrosis (CF) is one of the most frequent monogenic disease in the Caucasian population, inherited in an autosomal recessive pattern. This is a multiple organ disease and its main manifestations include pulmonary and gastrointestinal dysfunction. The exocrine pancreatic deficiency results in impaired digestion and absorption what may lead to malnutrition and vitamins and minerals deficiencies. The life expectancy of cystic fibrosis patients has been increasing over the past years, so there is a need to verify usefulness of existing or create new methods of nutritional status assessment. The aim of this paper was presentation current data on the methods of assessment and monitoring of nutritional status. Particular attention has been paid to appropriate nutritional support in prevention and treatment of malnutrition patients with cystic fibrosis. On the basis of recent literature we can conclude that the advanced nutritional status assessment is recommended in patient with CF by using anthropometrical methods, body composition analysis and biochemical data. Good nutritional status is connected with pulmonary functions, quality and life length. © 2015 MEDPRESS.

    There have been numerous global calls to action to utilize human resources information systems (HRIS) to improve the availability and quality of data for strengthening the regulation and deployment of health workers. However, with no normative guidance in existence, the development of HRIS has been inconsistent and lacking in standardization, hindering the availability and use of data for health workforce planning and decision making (Riley et al., 2012). CDC and WHO partnered with the Ministry of Health in several countries to conduct HRIS functional requirements analyses and establish a Minimum Data Set (MDS) of elements essential for a global standard HRIS. As a next step, CDC advanced a study to examine the alignment of one of the HRIS it supports (in Zimbabwe) against this MDS. For this study, we created a new data collection and analysis tool to assess the extent to which Zimbabwe's CDC-supported HRIS was aligned with the WHO MDS. We performed systematic "gap analyses" in order to make prioritized recommendations for addressing the gaps, with the aim of improving the availability and quality of data on Zimbabwe's health workforce. The majority of the data elements outlined in the WHO MDS were present in the ZHRIS databases, though they were found to be missing various applicable elements. The lack of certain elements could impede functions such as health worker credential verification or equitable in-service training allocation. While the HRIS MDS treats all elements equally, our assessment revealed that not all the elements have equal significance when it comes to data utilization. Further, some of the HRIS MDS elements exceeded the current needs of regulatory bodies and the Ministry of Health and Child Care (MOHCC) in Zimbabwe. The preliminary findings of this study helped inspire the development of a more recent HRH Registry MDS subset, which is a shorter list of priority data elements recommended as a global standard for HRIS.

    The principal aim of this study is to provide an account of variation in UK undergraduate medical assessment styles and corresponding standard setting approaches with a view to highlighting the importance of a UK national licensing exam in recognizing a common standard. Using a secure online survey system, response data were collected during the period 13 - 30 January 2014 from selected specialists in medical education assessment, who served as representatives for their respective medical schools. Assessment styles and corresponding choices of standard setting methods vary markedly across UK medical schools. While there is considerable consensus on the application of compensatory approaches, individual schools display their own nuances through use of hybrid assessment and standard setting styles, uptake of less popular standard setting techniques and divided views on norm referencing. The extent of variation in assessment and standard setting practices across UK medical schools validates the concern that there is a lack of evidence that UK medical students achieve a common standard on graduation. A national licensing exam is therefore a viable option for benchmarking the performance of all UK undergraduate medical students.

    The authors conducted this study to assess the quality of the information available on the Web about oral hygiene for patients with fixed orthodontic appliances. The authors entered the search terms "cleaning braces," "brushing braces," and "oral hygiene and braces" into Google, Yahoo, and Bing search engines. They analyzed Web sites satisfying the inclusion criteria from the first 20 hits of each search for accessibility, usability, and reliability by using the LIDA instrument; for readability by using the Flesch Reading Ease (FRE) score; and for the completeness of oral hygiene instructions. Sixty-two Web sites met the inclusion criteria. The mean total LIDA score of 71.2 indicated the moderate quality of the design of the reviewed Web sites. The mean (standard deviation [SD]) values of LIDA scores for accessibility, usability, and reliability were 85.9 (7.0), 63.4 (16.1), and 48.0 (10.4), respectively. The mean (SD) FRE Score of 68.6 (9.7) applied to standard reading skills. The completeness of information (mean [SD] = 67.1 [27.8]) presented the highest variability. Overall, the authors found that the standards of online oral hygiene materials for orthodontic patients with fixed appliances exhibited modest scores. Readability appeared to be appropriate for young adolescents, whereas the comprehensiveness of the displayed information was highly variable. Further improvement of the infrastructure of electronic health information (that is, e-health) in orthodontics is necessary to meet patients' needs. Given the moderate quality of oral hygiene instruction available on the Web for patients with fixed appliances, orthodontic patients and caregivers should be cautious when browsing the Internet for relevant information. Dental professionals should refer patients to valid Web-based educational materials. Copyright © 2015 American Dental Association. Published by Elsevier Inc. All rights reserved.

    Full Text Available Objectives: 1 to explore clinical assessor’s values regarding behaviours related to cultural aspects of care, 2 to generate standardized narrative profiles regarding cultural behavioural outcomes within clinical teaching settings, and 3 to rank order standardized narrative profiles according to performance expectations. Methods: Ten interviews were completed with clinicians to determine values and performance expectations for culturally competent behaviours. Transcripts were produced and coded. Six narrative profiles were developed based on data obtained. Twenty clinicians categorized profiles according to performance expectations and rank ordered. Intraclass correlation coefficients (ICCs determined inter-rater reliability. Clinicians rated usability of profiles in clinical training settings. Results: Eighteen categories were coded with communication, awareness and ability most frequently reported with each ranging from 9.6-11.5% of the utterances. Consensus for categorization of all profiles was achieved at a level of 70% (ICC = 0.837, 95% CI 0.654-0.969. High inter-rater reliability was achieved for rank ordering (ICC = 0.815, 95% CI 0.561 to 0.984. Seventeen (85% clinicians agreed that the profiles would be usable in clinical training settings. Conclusions: Standardized narrative profiles may aid assessment and self-reflection for student performance within culturally diverse interactions.

    One of the challenges with the sperm DNA fragmentation results is the inconsistency and the large variability in the results obtained by different techniques. The terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay quantifies the incorporation of fluoresceinated dUTP into single- and double-strand DNA breaks by labeling the 3'-OH terminal with TdT. The goal of this study was optimize the TUNEL protocol for assessment of sperm DNA fragmentation by standardization of the method and comparison of the data across two reference laboratories (i) at Basel, Switzerland and (ii) Cleveland Clinic, Ohio, USA. Semen samples from 31 subjects grouped into three cohorts. Sperm DNA fragmentation was data measured by two experienced operators at two different laboratories using identical semen samples, assay kit, protocol and acquisition settings using identical flow cytometers (BD Accuri C6). No significant differences were observed between the duplicates in any of the experiments performed. By including an additional washing step after fixation in paraformaldehyde, a high correlation was seen between the two laboratories (r = 0.94). A strong positive correlation was observed between the average sperm DNA fragmentation rates (r = 0.719). The mean sperm DNA fragmentation measured in each laboratory was similar. Both flow cytometers were identical in their settings and performance. This inter- and intra-laboratory study establishes that TUNEL is a reproducible assay when utilizing a standardized staining protocol and flow cytometer acquisition settings. Standardization and consensual guidelines for TUNEL validate the assay and establishes TUNEL as a robust test for measuring sperm DNA fragmentation especially in a multicenter setting. © 2017 American Society of Andrology and European Academy of Andrology.

    Full Text Available The Wada Test (WT is part of the presurgical evaluation for refractory epilepsy. The WT is not standardized and the protocols differ in important ways, including stimulus type of material presented for memory testing, timing of presentations and methods of assessment. The aim of this study was to contribute to establish parameters for a WT to Brazilian population investigating the performance of 100 normal subjects, without medication. Two parallel models were used based on Montreal Procedure adapted from Gail Risse's (MEG-MN,EUA protocol. The proportions of correct responses of normal subjects submitted to two parallel WT models were investigated and the two models were compared. The results showed that the two models are similar but significant differences among the stimulus type were observed. The results suggest that the stimulus type may influence the results of the WT and should be considered when constructing models and comparing different protocols.

    To develop a Standardized Donor Ratio (SDR) as an outcome measure for evaluating the effectiveness of organ procurement organizations (OPOs). All deaths by cause in the United States during 1993-1994 as reported in the Vital Mortality Statistics, Multiple Cause of Death files. The OPO-specific data were provided by the United Network for Organ Sharing (UNOS). Each OPO's expected number of donors was calculated by applying national donation rates to deaths with potential for donation in 24 age, sex, and race cells. The SDR was calculated by dividing the observed number of donors by the expected number. The chi2 tests of the hypothesis that the OPO's performance differed from the national norm of 1.0 were performed. The SDR was compared to the existing performance standard based on the unadjusted number of donors per million live population in the OPO's service area. An ordinary least squares (OLS) regression assessed predictors of the SDR. The SDRs ranged from 0.41 to 1.99. Twenty-nine of 64 OPOs had SDRs significantly different than 1.0. The SDRs were positively associated with the percent of white living population and the number of organ types transplanted per transplant center served by the OPO. The SDRs can be used by Centers for Medicare and Medicaid Services (CMS), UNOS, and OPOs to target quality improvement initiatives, present more accurate comparisons of OPO performance, and develop public policy on the evaluation of the effectiveness of organ procurement efforts.

  9. Assessment of human sleep depth is being de-standardized by recently advised EEG electrode locations.

    Directory of Open Access Journals (Sweden)

    Bob Kemp

    Full Text Available Human sleep depth was traditionally assessed by scoring electro-encephalographic slow-wave amplitudes at the globally standardized C4-M1 electrode derivation. Since 2007, the American Association of Sleep Medicine (AASM has accepted three additional derivations for the same purpose. These might well differ in slow wave amplitudes which would bias the scorings. Some derivations might also introduce large inter-individual variability. We compared mean and variability of slow wave amplitudes between six derivations including the four AASM ones. Slow wave amplitudes in those derivations were simultaneously measured using automated analysis in 29 patients. Each amplitude was divided by the average from the six derivations, thus removing shared factors such as age, gender and sleep depth while retaining factors that differ between the derivations such as caused by local skull characteristics, electrode distance and neuronal dipole orientation. The remaining inter-individual variability differed significantly and up to a factor of two between the AASM derivations. The amplitudes differed significantly and up to 60% between the AASM derivations, causing substantial scoring bias between centres using different derivations. The resulting de-standardization most likely affects any patient group because the amplitude differences were consistent over diagnoses, genders, and age. Derivation-dependent amplitude thresholds were proposed to reduce the scoring bias. However, it would be better to settle on just one derivation, for instance Cz-Oz or Fpz-Cz because these have lowest variability while matching the traditional C4-M1 amplitudes.

    2003-01-01

    Background: The burden of parasitic disease imported into the temperate zone is increasing, and in the tropics remains very high. Thus, high quality diagnostic parasitology services are needed, but to implement clinical governance a measure of quality of service is required. Aim: To examine performance in the United Kingdom National External Quality Assessment Scheme for Parasitology for evidence of improved standards in parasite diagnosis in clinical specimens. Methods: Analysis of performance was made for the period 1986 to 2001, to look for trends in performance scores. Results: An overall rise in performance in faecal and blood parasitology schemes was found from 1986 to 2001. This was seen particularly in the identification of ova, cysts, and larvae in the faecal scheme, the detection of Plasmodium ovale and Plasmodium vivax in the blood scheme, and also in the correct identification of non-malarial blood parasites. Despite this improvement, there are still problems. In the faecal scheme, participants still experience difficulty in recognising small protozoan cysts, differentiating vegetable matter from cysts, and detecting ova and cysts when more than one species is present. In the blood scheme, participants have problems in identifying mixed malarial infections, distinguishing between P ovale and P vivax, and estimating the percentage parasitaemia. The reasons underlying these problems have been identified via the educational part of the scheme, and have been dealt with by distributing teaching sheets and undertaking practical sessions. Conclusions: UK NEQAS for Parasitology has helped to raise the standard of diagnostic parasitology in the UK. PMID:14645352

  11. Assessing the National Bioengineered Food Disclosure Standard of 2016: Can Americans Access Electronic Disclosure Information?

    Directory of Open Access Journals (Sweden)

    Craig F. Berning

    2017-05-01

    Full Text Available The debate as to whether to require mandatory labeling of genetically modified organism (GMO foods was partially settled on 29 July 2016, when President Obama signed the National Bioengineered Food Disclosure Standard into public law. In contrast to precipitating legislation passed by the State of Vermont that required disclosure of GMO ingredients on food shelves or food packages, the superseding National Standard allows firms to disclose bioengineered ingredients to consumers via symbols, electronic or digital links, or phone numbers, and further requires a study assessing the ability of consumers to access disclosure information by these means. This communication analyzes survey responses from 525 adults to investigate whether U.S. consumers are able to obtain information as per the disclosure methods allowed in the Federal legislation. The survey probes deeper to investigate consumer perceptions of genetically modified organisms and whether consumers would use the tools available to access disclosure about bioengineered ingredients. Findings from the survey show that 93.8% of respondents have the ability to access information via the disclosure methods permitted. Those in the lowest income group, and from the oldest age group are least likely to have such access. This provides the United State Department of Agriculture with information relevant to how they can implement the law and highlights particular demographic segments that may require additional attention to ensure the disclosed information is universally accessible.

    We assessed the sensitivity and specificity of 8 electronic health record (EHR)-based phenotypes for diabetes mellitus against gold-standard American Diabetes Association (ADA) diagnostic criteria via chart review by clinical experts. We identified EHR-based diabetes phenotype definitions that were developed for various purposes by a variety of users, including academic medical centers, Medicare, the New York City Health Department, and pharmacy benefit managers. We applied these definitions to a sample of 173 503 patients with records in the Duke Health System Enterprise Data Warehouse and at least 1 visit over a 5-year period (2007-2011). Of these patients, 22 679 (13%) met the criteria of 1 or more of the selected diabetes phenotype definitions. A statistically balanced sample of these patients was selected for chart review by clinical experts to determine the presence or absence of type 2 diabetes in the sample. The sensitivity (62-94%) and specificity (95-99%) of EHR-based type 2 diabetes phenotypes (compared with the gold standard ADA criteria via chart review) varied depending on the component criteria and timing of observations and measurements. Researchers using EHR-based phenotype definitions should clearly specify the characteristics that comprise the definition, variations of ADA criteria, and how different phenotype definitions and components impact the patient populations retrieved and the intended application. Careful attention to phenotype definitions is critical if the promise of leveraging EHR data to improve individual and population health is to be fulfilled.

    Concerns about quality of care have led to the integration of patient safety standards and goals in national and international accreditation programs. Since 2005, two national hospital accreditation surveys have been conducted in Lebanon. In 2010, the Ministry of Health integrated patient safety standards into the current program. This study is one of the first efforts in Lebanon and the region to assess hospitals' readiness to integrate patient safety standards into routine practice. This cross-sectional study sampled 6807 respondents from 68 hospitals in Lebanon. This paper will detail results from the qualitative thematic analysis of the responses on 5 open-ended questions added to the Hospital Survey on Patient Safety Culture. The emerging themes were compared across regions, accreditation status, and hospital size. Lebanese hospitals have made progress by recognizing patient safety as a major strategic goal and priority, but gaps still exist in implementation. Very few hospitals are ready for effective implementation of these standards. Staff education and training are needed. Public awareness about patient safety and integrating these concepts into health educational curricula were cited as important strategies among others for creating a culture of patient safety. Variations in responses across regions, accreditation status, and hospital size were discussed. Integrating patient safety initiatives into routine practices requires a cultural shift in health-care organizations. Before assessing whether hospitals comply with patient safety standards, it is important to provide them with sufficient training and education on how to successfully implement these standards. Study findings provide valuable lessons for Lebanon and other countries, which are in the process or currently mandating the implementation of patient safety standards and/or accreditation programs.

    The implications of undertaking DXA scans using best practice protocols (subjects fasted and rested) or a less precise but more practical protocol in assessing chronic changes in body composition following training and a specialized recovery technique were investigated. Twenty-one male cyclists completed an overload training program, in which they were randomized to four sessions per week of either cold water immersion therapy or control groups. Whole-body DXA scans were undertaken with best practice protocol (Best) or random activity protocol (Random) at baseline, after 3 weeks of overload training, and after a 2-week taper. Magnitudes of changes in total, lean and fat mass from baseline-overload, overload-taper and baseline-taper were assessed by standardization (Δmean/SD). The standard deviations of change scores for total and fat-free soft tissue mass (FFST) from Random scans (2-3%) were approximately double those observed in the Best (1-2%), owing to extra random errors associated with Random scans at baseline. There was little difference in change scores for fat mass. The effect of cold water immersion therapy on baseline-taper changes in FFST was possibly harmful (-0.7%; 90% confidence limits ±1.2%) with Best scans but unclear with Random scans (0.9%; ±2.0%). Both protocols gave similar possibly harmful effects of cold water immersion therapy on changes in fat mass (6.9%; ±13.5% and 5.5%; ±14.3%, respectively). An interesting effect of cold water immersion therapy on training-induced changes in body composition might have been missed with a less precise scanning protocol. DXA scans should be undertaken with Best.

    The severity of white matter lesions (WML) is a risk factor of hemorrhage and predictor of clinical outcome after ischemic stroke; however, in contrast to magnetic resonance imaging (MRI) reliable quantification for this surrogate marker is limited for computed tomography (CT), the leading stroke imaging technique. We aimed to present and evaluate a CT-based automated rater-independent method for quantification of microangiopathic white matter changes. Patients with suspected minor stroke (National Institutes of Health Stroke scale, NIHSS < 4) were screened for the analysis of non-contrast computerized tomography (NCCT) at admission and compared to follow-up MRI. The MRI-based WML volume and visual Fazekas scores were assessed as the gold standard reference. We employed a recently published probabilistic brain segmentation algorithm for CT images to determine the tissue-specific density of WM space. All voxel-wise densities were quantified in WM space and weighted according to partial probabilistic WM content. The resulting mean weighted density of WM space in NCCT, the surrogate of WML, was correlated with reference to MRI-based WML parameters. The process of CT-based tissue-specific segmentation was reliable in 79 cases with varying severity of microangiopathy. Voxel-wise weighted density within WM spaces showed a noticeable correlation (r = -0.65) with MRI-based WML volume. Particularly in patients with moderate or severe lesion load according to the visual Fazekas score the algorithm provided reliable prediction of MRI-based WML volume. Automated observer-independent quantification of voxel-wise WM density in CT significantly correlates with microangiopathic WM disease in gold standard MRI. This rapid surrogate of white matter lesion load in CT may support objective WML assessment and therapeutic decision-making during acute stroke triage.

    Oral and maxillofacial surgeons who perform orthognathic surgery face major changes in their practices, and these challenges will increase in the near future, because the extraordinary advances in technology applied to our profession are not only amazing but are becoming the standard of care as they promote improved outcomes for our patients. Orthognathic surgery is one of the favorite areas of practicing within the scope of practice of an oral and maxillofacial surgeon. Our own practice in orthognathic surgery has completed over 1,000 surgeries of this type. Success is directly related to the consistency and capability of the surgical-orthodontic team to achieve predictable, stable results, and our hypothesis is that a successful result is directly related to the way we take our records and perform diagnosis and treatment planning following basic general principles. Now that we have the opportunity to plan and treat 3-dimensional (3D) problems with 3D technology, we should enter into this new era with appropriate standards to ensure better results, instead of simply enjoying these new tools, which will clearly show not only us but everyone what we do when we perform orthognathic surgery. Appropriate principles need to be taken into account when implementing this new technology. In other words, new technology is welcome, but we do not have to reinvent the wheel. The purpose of this article is to review the current protocol that we use for orthognathic surgery and compare it with published protocols that incorporate new 3D and virtual technology. This report also describes our approach to this new technology. Copyright © 2011 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.

    Automatic segmentation of the endocardial surface in three-dimensional (3D) echocardiographic images is an important tool to assess left ventricular (LV) geometry and cardiac output (CO). The presence of speckle noise as well as the nonisotropic characteristics of the myocardium impose strong demands on the segmentation algorithm. In the analysis of normal heart geometries of standardized (apical) views, it is advantageous to incorporate a priori knowledge about the shape and appearance of the heart. In contrast, when analyzing abnormal heart geometries, for example in children with congenital malformations, this a priori knowledge about the shape and anatomy of the LV might induce erroneous segmentation results. This study describes a fully automated segmentation method for the analysis of non-standard echocardiographic images, without making strong assumptions on the shape and appearance of the heart. The method was validated in vivo in a piglet model. Real-time 3D echocardiographic image sequences of five piglets were acquired in radiofrequency (rf) format. These ECG-gated full volume images were acquired intra-operatively in a non-standard view. Cardiac blood flow was measured simultaneously by an ultrasound transit time flow probe positioned around the common pulmonary artery. Three-dimensional adaptive filtering using the characteristics of speckle was performed on the demodulated rf data to reduce the influence of speckle noise and to optimize the distinction between blood and myocardium. A gradient-based 3D deformable simplex mesh was then used to segment the endocardial surface. A gradient and a speed force were included as external forces of the model. To balance data fitting and mesh regularity, one fixed set of weighting parameters of internal, gradient and speed forces was used for all data sets. End-diastolic and end-systolic volumes were computed from the segmented endocardial surface. The cardiac output derived from this automatic segmentation was

    2002-01-01

    The purpose of this article is to introduce the cross-disciplinary competency standards for work-related assessments, why they are needed and how they have been developed in New South Wales (NSW). Cross-disciplinary competency standards communicate the benchmarks for effective performance of work-related assessments. They outline what is expected of rehabilitation professionals, including the ability to apply and transfer competence across different conditions and workplace contexts. Outcomes in occupational rehabilitation are affected by the efficacy of the work-related assessments performed, which is dependent upon competent, clinical decision-making by rehabilitation professionals. However, in Australia, work-related assessment practice is not governed by universally accepted competency standards or by any competency-based training/education and assessment system. To enhance professional practice, WorkCover NSW has developed cross-disciplinary competency standards for work-related a ssessments. The competencies provide (i) quality standards for professional workplace training and development, (ii) benchmarks for assessing the competence of rehabilitation professionals, (iii) a framework for evidence-based practice, (iv) benchmarks for measuring service quality and (v) "real world" learning outcomes and assessment criteria for professional education programs.

  2. Specification of Energy Assessment Methodologies to Satisfy ISO 50001 Energy Management Standard

    Science.gov (United States)

    Kanneganti, Harish

    Energy management has become more crucial for industrial sector as a way to lower their cost of production and in reducing their carbon footprint. Environmental regulations also force the industrial sector to increase the efficiency of their energy usage. Hence industrial sector started relying on energy management consultancies for improvements in energy efficiency. With the development of ISO 50001 standard, the entire energy management took a new dimension involving top level management and getting their commitment on energy efficiency. One of the key requirements of ISO 50001 is to demonstrate continual improvement in their (industry) energy efficiency. The major aim of this work is to develop an energy assessment methodology and reporting format to tailor the needs of ISO 50001. The developed methodology integrates the energy reduction aspect of an energy assessment with the requirements of sections 4.4.3 (Energy Review) to 4.4.6 (Objectives, Targets and Action Plans) in ISO 50001 and thus helping the facilities in easy implementation of ISO 50001.

    This paper presents'new correlations for assessment of the likelihood of initiation (or triggering) of soil liquefaction. These new correlations eliminate several sources of bias intrinsic to previous, similar correlations, and provide greatly reduced overall uncertainty and variance. Key elements in the development of these new correlations are (1) accumulation of a significantly expanded database of field performance case histories; (2) use of improved knowledge and understanding of factors affecting interpretation of standard penetration test data; (3) incorporation of improved understanding of factors affecting site-specific earthquake ground motions (including directivity effects, site-specific response, etc.); (4) use of improved methods for assessment of in situ cyclic shear stress ratio; (5) screening of field data case histories on a quality/uncertainty basis; and (6) use of high-order probabilistic tools (Bayesian updating). The resulting relationships not only provide greatly reduced uncertainty, they also help to resolve a number of corollary issues that have long been difficult and controversial including: (1) magnitude-correlated duration weighting factors, (2) adjustments for fines content, and (3) corrections for overburden stress. ??

    The growing need for valid assessment procedures of the outdoor thermal environment in the fields of public weather services, public health systems, urban planning, tourism & recreation and climate impact research raised the idea to develop the Universal Thermal Climate Index UTCI based on the most recent scientific progress both in thermo-physiology and in heat exchange theory. Following extensive validation of accessible models of human thermoregulation, the advanced multi-node 'Fiala' model was selected to form the basis of UTCI. This model was coupled with an adaptive clothing model which considers clothing habits by the general urban population and behavioral changes in clothing insulation related to actual environmental temperature. UTCI was developed conceptually as an equivalent temperature. Thus, for any combination of air temperature, wind, radiation, and humidity, UTCI is defined as the air temperature in the reference condition which would elicit the same dynamic response of the physiological model. This review analyses the sensitivity of UTCI to humidity and radiation in the heat and to wind in the cold and compares the results with observational studies and internationally standardized assessment procedures. The capabilities, restrictions and potential future extensions of UTCI are discussed.

    While hydroxycarbamide (hydroxyurea, HU) has less and fewer indications in malignant hemopathies, it represents the only widely used drug which modifies sickle cell disease pathogenesis. Clinical experience with HU for patients with sickle cell disease has been accumulated over the past 25 years in Western countries. The review of the literature provides increasing support for safety and efficacy in both children and adults for reducing acute vaso-occlusive events including pain episodes and acute chest syndrome. No increased incidence of leukemia and teratogenicity was demonstrated. HU has become the standard-of-care for sickle cell anemia but remains underused. Barriers to its use should be identified and overcome. PMID:28293403

Methods: The Self-assessment for Hearing Screening of the Elderly (SHSE consisted of 20 questions based on the characteristics of presbycusis using a five-point scale: seven questions covered general issues related to sensorineural hearing loss, seven covered hearing difficulty under distracting listening conditions, two covered hearing difficulty with fast-rated speech, and four covered the working memory function during communication. To standardize SHSE, 83 elderly participants took part in the study: 25 with normal hearing, and 22, 23, and 13 with mild, moderate, and moderate-to-severe sensorineural hearing loss, respectively, according to their hearing sensitivity. All were retested 3 weeks later using the same questionnaire to confirm its reliability. In addition, validity was assessed using various hearing tests such as a sentence test with background noise, a time-compressed speech test, and a digit span test. Results: SHSE and its subcategories showed good internal consistency. SHSE and its subcategories demonstrated high test–retest reliability. A high correlation was observed between the total scores and pure-tone thresholds, which indicated gradually increased SHSE scores of 42.24%, 55.27%, 66.61%, and 78.15% for normal hearing, mild, moderate, and moderate-to-severe groups, respectively.

    Neglecting occupational safety and health (OSH) can have adverse and even deadly consequences. While OSH is important in any nation, the issue is particularly concerning in developing countries, including ones in the Caribbean. The purpose of this study, which was carried out in 2012 and 2013, was to examine the reasons for an apparent fundamental lack of awareness of OSH in the Caribbean. We conducted a descriptive study, in which a questionnaire was administered, via telephone, to key policy-making representatives from six English-speaking Caribbean nations, in order to assess the current OSH environment in their countries. We also did a situational analysis of current OSH regulations and legislation within the six countries. We found that that some of the countries' OSH laws are out of date or are limited to a certain type of industry. We also found that there is very little documentation on research on exposure to and risks from hazards and on psychological and reproductive health as related to OSH. It is recommended that these Caribbean countries both increase national OSH awareness and strengthen enforcement of OSH regulations. Additionally, further assistance and a more coordinated effort from intergovernmental bodies could help build and fortify OSH systems in the Caribbean.

    Measurement of tremor has been used in several occupational studies of workers with long-term exposure to mercury vapor (Hg(0)). Recent studies indicate an adverse effect even at relatively low exposure levels. In the present study, we used sensitive quantitative methods to assess tremor in chloralkali workers with current low exposure to Hg(0). Neurological examinations and recordings of tremor using both an accelerometer and a laser-based system were conducted in 43 mercury-exposed workers and 22 age-matched referents. The median urinary mercury concentration in exposed workers was 5.9 (1.3-25) microg/g creatinine (microg/gC), while it was 0.7 (0.2-4.1) microg/gC in referents. The mean exposure time was 15 years, and the median cumulative mercury index was 161 years x microg/gC in exposed workers. There were no differences between the exposed workers and the referents in the clinical evaluation of tremor. In the quantitative tremor tests, no associations were found with current or cumulative mercury exposure for the majority of tremor measures. There were indications that exposure to Hg(0) was associated with a lowering of tremor frequency in the non-dominant hand, and a possible interaction with smoking. The differences were small, however, and overall, this study indicates no significant adverse effects on tremor at these exposure levels.

    Full Text Available Background. Tanzania started a countrywide lymphatic filariasis elimination programme in 2000 adopting the mass drug administration (MDA strategy. The drug used for the programme was the combination of ivermectin and albendazole. However, there is limited information on the current epidemiological trend of the infections, where MDA implementation is ongoing. The present study aimed at assessing the current status of Bancroftian filariasis infection rate and morbidity where MDA has been distributed and administered for over eight rounds. Methodology. The study was a cross-sectional descriptive study involving 272 individuals (>18 years from endemic communities in Tanga region where MDA has been implemented. Clinical, sociodemographic, and circulating filarial antigen (CFA test was undertaken using immune chromatographic card test according to the manufacturer’s instructions. Results. A total of 472 individuals were screened: 307/472 (65.1% were males while 165/472 (34.9% were females. The overall prevalence of CFA was 5.51%, that of hydrocoele was 73.2%, and that of lymphoedema was 16.0%. The prevalence of hydrocoele combined with lymphoedema was 5.5%. Conclusion. Our findings demonstrate a considerable reduction in filarial infection. However, there is clear evidence of ongoing transmission despite the 8 rounds of MDA. It is unlikely that the annual MDA would interrupt filarial transmission; therefore, additional strategies are needed to accelerate lymphatic filariasis control and elimination.

    Improving the reading performance of children with developmental surface dyslexia has proved challenging, with limited generalisation of reading skills typically reported after intervention. The aim of this study was to provide tailored, theoretically motivated intervention to two children with developmental surface dyslexia. Our objectives were to improve their reading performance, and to evaluate the utility of current reading models in therapeutic practice. Detailed reading and cognitive profiles for two male children with developmental surface dyslexia were compared to the results obtained by age-matched control groups. The specific area of single-word reading difficulty for each child was identified within the dual route model (DRM) of reading, following which a theoretically motivated intervention programme was devised. Both children showed significant improvements in single-word reading ability after training, with generalisation effects observed for untrained words. However, the assessment and intervention results also differed for each child, reinforcing the view that the causes and consequences of developmental dyslexia, even within subtypes, are not homogeneous. Overall, the results of the interventions corresponded more closely with the DRM than other current reading models, in that real word reading improved in the absence of enhanced nonword reading for both children.

    A program to demonstrate Solvent Refined Coal (SRC) technology has been initiated by the US Department of Energy (DOE) in partnership with two industrial groups. Project management responsibility has been assigned to the Oak Ridge Operations Office (ORO) of DOE. ORO requested that the Oak Ridge National Laboratory assess current research and development (R and D) activities and develop recommendations for those activities that might contribute to successful completion of the SRC demonstration plant projects. The objectives of this final report are to discuss in detail the problem areas in SRC; to discuss the current and planned R and D investigations relevant to the problems identified; and to suggest appropriate R and D activities in support of designs for the SRC demonstration plants. Four types of R and D activities are suggested: continuation of present and planned activities; coordination of activities and results, present and proposed; extension/redirection of activities not involving major equipment purchase or modifications; and new activities. Important examples of the first type of activity include continuation of fired heater, slurry rheology, and slurry mixing studies at Ft. Lewis. Among the second type of activity, coordination of data acquisition and interpretation is recommended in the areas of heat transfer, vapor/liquid equilibria, and physical properties. Principal examples of recommendations for extension/redirection include screening studies at laboratory scale on the use of carbonaceous precoat (e.g., anthracite) infiltration, and 15- to 30-day continuous tests of the Texaco gasifier at the Texaco Montebello facility (using SRC residues).

    Having an effective triage tool is an important step toward a careful use of the restricted time and qualified personnel to perform comprehensive psychiatric assessment in juvenile justice settings. The aims of this study were to examine the construct validity of the Massachusetts Youth Screening Inventory-second version (MAYSI-2), and its likelihood to identify youths who might have a psychiatric disorder. Data from up to 781 male adolescents (mean age = 16.73 years) were gathered as part of the standardized mental health screening and assessment in two all-male Youth Detention Centers in the Netherlands. Categorical assessments were based on two structured diagnostic interviews. Sensitivity, specificity, positive and negative predictive values, and the area under the curve were calculated to evaluate the likelihood of the MAYSI-2 to identify youths with a psychiatric disorder. Youths with a disorder scored significantly higher on the corresponding MAYSI-2 subscale than youths without a disorder. In the total sample, 70 % of the youths with a disorder met the Caution cut-off criteria on at least one MAYSI-2 scale, while youths without a psychiatric disorder were very unlikely to meet cut-off criteria for multiple MAYSI-2 scales. Overall, the sensitivity was slightly better when analyses were repeated in groups of youths from various ethnic origins. The findings supported the construct validity of the Dutch MAYSI-2 and suggested that the MAYSI-2 is a valid mental health screening tool that may serve relatively well as a triage tool. Its effectiveness, however, may differ between ethnic groups.

  16. Standardizing the protocol for hemispherical photographs: accuracy assessment of binarization algorithms.

    Full Text Available Hemispherical photography is a well-established method to optically assess ecological parameters related to plant canopies; e.g. ground-level light regimes and the distribution of foliage within the crown space. Interpreting hemispherical photographs involves classifying pixels as either sky or vegetation. A wide range of automatic thresholding or binarization algorithms exists to classify the photographs. The variety in methodology hampers ability to compare results across studies. To identify an optimal threshold selection method, this study assessed the accuracy of seven binarization methods implemented in software currently available for the processing of hemispherical photographs. Therefore, binarizations obtained by the algorithms were compared to reference data generated through a manual binarization of a stratified random selection of pixels. This approach was adopted from the accuracy assessment of map classifications known from remote sensing studies. Percentage correct (Pc and kappa-statistics (K were calculated. The accuracy of the algorithms was assessed for photographs taken with automatic exposure settings (auto-exposure and photographs taken with settings which avoid overexposure (histogram-exposure. In addition, gap fraction values derived from hemispherical photographs were compared with estimates derived from the manually classified reference pixels. All tested algorithms were shown to be sensitive to overexposure. Three of the algorithms showed an accuracy which was high enough to be recommended for the processing of histogram-exposed hemispherical photographs: "Minimum" (Pc 98.8%; K 0.952, "Edge Detection" (Pc 98.1%; K 0.950, and "Minimum Histogram" (Pc 98.1%; K 0.947. The Minimum algorithm overestimated gap fraction least of all (11%. The overestimation by the algorithms Edge Detection (63% and Minimum Histogram (67% were considerably larger. For the remaining four evaluated algorithms (IsoData, Maximum Entropy, Min

    Given the high incidence of burn injuries in children, it is important that all clinicians involved in the care of these patients, including occupational therapists and physiotherapists, are able to assess patients with valid, sensitive, and reliable measurement tools to optimize outcomes and clinical management. The aims of this study were to identify therapist- relevant outcome measurement tools that have been previously used with pediatric burn patients and to ascertain the outcome measurement tools currently used by occupational therapists and physiotherapists working in pediatric burns units. A literature review was undertaken to identify therapist-relevant outcome measurement tools that have been used in the pediatric burn population. A survey involving therapists working in Australian pediatric burns units was then conducted to identify outcome measurement tools in common usage. Few outcome measurement tools were identified that had been specifically validated for use, or were in common usage in Australia, with pediatric patients with burn injury. The lack of validated and widely used measurement tools adversely impacts on the ability of therapists to accurately assess outcomes of treatment and undertake clinical research involving pediatric patients with burn injury.

    Recently occurred failures in water supply system derived from lacking rainfall in Korea has raised severe concerns about limited water resources exacerbated by anthropogenic drivers as well as climatic changes. Since Korea is under unprecedented changes in both social and environmental aspects, it is required to integrate social and environmental changes as well as climate factors in order to consider underlying problems and their upcoming impacts on sustainable water use. In this study, we proposed a framework to assess multilateral aspects in sustainable water use in support of performance-based monitoring. The framework is consisted of four thematic indices (climate, infrastructure, pollution, and management capacity) and subordinate indicators. Second, in order to project future circumstances, climate variability, demographic, and land cover scenarios to 2050 were applied after conducting statistical analysis identifying correlations between indicators within the framework since water crisis are caused by numerous interrelated factors. Assessment was conducted throughout 161 administrative boundaries in Korea at the time of 2010, 2030, and 2050. Third, current and future status in water use were illustrated using GIS-based methodology and statistical clustering (K-means and HCA) to elucidate spatially explicit maps and to categorize administrative regions showing similar phenomenon in the future. Based on conspicuous results shown in spatial analysis and clustering method, we suggested policy implementations to navigate local communities to decide which countermeasures should be supplemented or adopted to increase resiliency to upcoming changes in water use environments.

  19. THE ASSESSMENT OF ENTREPRENEURIAL PERSONALITY: THE CURRENT SITUATION AND FUTURE DIRECTIONS

    Full Text Available Entrepreneurship is fundamental in modern society because it represents an important source of innovation, employment, productivity, and growth. While the first theoretical models arose from economic and sociological approaches, psychology provides models that integrate different aspects such as cognitions, attitudes and personality, which allow a more detailed study. The purpose of this paper is to show the main contributions of psychology to the assessment of the enterprising personality. For this purpose, the main models and instruments developed to date were reviewed. The results confirm that the enterprising personality has a multidimensional structure and eight personality traits can be highlighted: achievement motivation, risk-taking, autonomy, self-efficacy, stress tolerance, innovativeness, internal locus of control, and optimism. From a methodological point of view, Item Response Theory and Computerised Adaptive Tests represent the most advanced and modern methods for assessing enterprising personality. There are currently several measurement instruments available. Future areas of research should be directed at the construction of multidimensional models as well as providing alternatives that facilitate a reduction in social desirability and other biases inherent in self-reports.

    Nutritional states of Japanese patients with liver cirrhosis have recently shown great diversity, some show protein energy malnutrition and others excessive nutrition and obesity. For there to be adequate guidance regarding dietary treatment, it is important that a patient's current nutritional state be clarified. We assessed nutritive intake in Japanese cirrhotic patients and determined their nutritional problems. Subjects were non-hospitalized patients with hepatitis C virus (HCV)-related cirrhosis in the compensated stage (n=47), chronic hepatitis C (n=46) or healthy volunteers (n=32). A brief self-administered diet history questionnaire was conducted with assistance from a registered dietitian. We categorized patients with cirrhosis according to daily intake of energy and protein; 10.6% had an energy and protein intake within a normal range, 72.4% showed excessive intake, and 17.0% showed insufficient intake of energy or protein. In cirrhotic patients with diabetic complications, the intake levels of energy, proteins, fat and carbohydrates were significantly higher than in patients without diabetes. Moreover, cirrhotic patients had significantly higher intake levels of energy, protein and fat than did chronic hepatitis C patients and healthy individuals. In patients with HCV-related liver cirrhosis, insufficient intake of energy and protein was shown in some, while many, especially those with diabetes, showed excessive intake. For nutritive management of cirrhotic patients, the intake of various nutrients should be appropriately assessed and effective nutritional education systems established.

    Chest pain is one of the most common presenting symptoms leading to presentation to medical clinics and Emergency Departments worldwide. Defining the nature and etiology of chest pain can pose a diagnostic dilemma for clinicians, despite the availability of several diagnostic algorithms and guidelines to assist them in evaluating these patients. Most investigations in patients with acute chest pain are initially performed to either exclude or diagnose and manage potentially life-threatening conditions such as acute coronary syndrome, pulmonary embolism and aortic dissection. In cases of stable chest pain syndromes, the focus shifts to determining the presence, extent and severity of coronary artery disease. In recent years, coronary computed tomography angiography (CCTA) is being increasingly used worldwide in the assessment of both stable and acute chest pain syndromes. This review evaluates the current evidence regarding the clinical utility of CCTA in the stable and acute chest pain settings and outlines the latest advances in CCTA techniques, including functional assessment of coronary stenoses, and their potential clinical application to improve patient care in a cost-effective manner.

    Emergency ultrasound (EUS) has been recognized as integral to the training and practice of emergency medicine (EM). The Council of Emergency Medicine Residency-Academy of Emergency Ultrasound (CORD-AEUS) consensus document provides guidelines for resident assessment and progression. The Accredited Council for Graduate Medical Education (ACGME) has adopted the EM Milestones for assessment of residents' progress during their residency training, which includes demonstration of procedural competency in bedside ultrasound. The objective of this study was to assess EM residents' use of ultrasound and perceptions of the proposed ultrasound milestones and guidelines for assessment. This study is a prospective stratified cluster sample survey of all U.S. EM residency programs. Programs were stratified based on their geographic location (Northeast, South, Midwest, West), presence/absence of ultrasound fellowship program, and size of residency with programs sampled randomly from each stratum. The survey was reviewed by experts in the field and pilot tested on EM residents. Summary statistics and 95% confidence intervals account for the survey design, with sampling weights equal to the inverse of the probability of selection, and represent national estimates of all EM residents. There were 539 participants from 18 residency programs with an overall survey response rate of 85.1%. EM residents considered several applications to be core applications that were not considered core applications by CORD-AEUS (quantitative bladder volume, diagnosis of joint effusion, interstitial lung fluid, peritonsillar abscess, fetal presentation, and gestational age estimation). Of several core and advanced applications, the Focused Assessment with Sonography in Trauma examination, vascular access, diagnosis of pericardial effusion, and cardiac standstill were considered the most likely to be used in future clinical practice. Residents responded that procedural guidance would be more crucial to

  9. Adaptive capacity indicators to assess sustainability of urban water systems - Current application.

    Science.gov (United States)

    Spiller, Marc

    2016-11-01

    Sustainability is commonly assessed along environmental, societal, economic and technological dimensions. A crucial aspect of sustainability is that inter-generational equality must be ensured. This requires that sustainability is attained in the here and now as well as into the future. Therefore, what is perceived as 'sustainable' changes as a function of societal opinion and technological and scientific progress. A concept that describes the ability of systems to change is adaptive capacity. Literature suggests that the ability of systems to adapt is an integral part of sustainable development. This paper demonstrates that indicators measuring adaptive capacity are underrepresented in current urban water sustainability studies. Furthermore, it is discussed under which sustainability dimensions adaptive capacity indicators are lacking and why. Of the >90 indicators analysed, only nine are adaptive capacity indicators, of which six are socio-cultural, two technological, one economical and none environmental. This infrequent use of adaptive capacity indicators in sustainability assessments led to the conclusion that the challenge of dynamic and uncertain urban water systems is, with the exception of the socio-cultural dimension, not yet sufficiently reflected in the application of urban water sustainability indicators. This raises concerns about the progress towards urban water systems that can transform as a response variation and change. Therefore, research should focus on developing methods and indicators that can define, evaluate and quantify adaptive capacity under the economic, environmental and technical dimension of sustainability. Furthermore, it should be evaluated whether sustainability frameworks that focus on the control processes of urban water systems are more suitable for measuring adaptive capacity, than the assessments along environmental, economic, socio-cultural and technological dimensions.

    Bernert, Rebecca A; Hom, Melanie A; Roberts, Laura Weiss

    2014-10-01

    The current paper aims to: (1) examine clinical practice guidelines in suicide prevention across fields, organizations, and clinical specialties and (2) inform emerging standards in clinical practice, research, and training. The authors conducted a systematic literature review to identify clinical practice guidelines and resource documents in suicide prevention and risk management. The authors used PubMed, Google Scholar, and Google Search, and keywords included: clinical practice guideline, practice guideline, practice parameters, suicide, suicidality, suicidal behaviors, assessment, and management. To assess for commonalities, the authors reviewed guidelines and resource documents across 13 key content categories and assessed whether each document suggested validated assessment measures. The search generated 101 source documents, which included N = 10 clinical practice guidelines and N = 12 additional resource documents (e.g., non-formalized guidelines, tool-kits). All guidelines (100 %) provided detailed recommendations for the use of evidence-based risk factors and protective factors, 80 % provided brief (but not detailed) recommendations for the assessment of suicidal intent, and 70 % recommended risk management strategies. By comparison, only 30 % discussed standardization of risk-level categorizations and other content areas considered central to best practices in suicide prevention (e.g., restricting access to means, ethical considerations, confidentiality/legal issues, training, and postvention practices). Resource documents were largely consistent with these findings. Current guidelines address similar aspects of suicide risk assessment and management, but significant discrepancies exist. A lack of consensus was evident in recommendations across core competencies, which may be improved by increased standardization in practice and training. Additional resources appear useful for supplemental use.

    2004-05-01

    We examined the use of figural rating scales to measure body dissatisfaction and the ideal body standards of women. We also attended to the potential influence of demand characteristics in body assessment research using these measures, a methodological concern largely ignored in this field. We used both within- and between-subjects designs to assess whether women hold different body standards for themselves compared to their same sex peers and whether their own ideal body size (IBS) is different from what they think men prefer. Regardless of the method of data collection (within or between design), we failed to find any differences on separate items of body image ideals. The findings do provide evidence of robust and large effects for the current-ideal discrepancy as measured by figural rating scales, but argue against including multiple questions about ideal body preferences on these types of scales. Concerns about the influence of demand characteristics were not supported by the data.

    Beaulieu, Joyce; Scutchfield, F Douglas

    2002-01-01

    The National Public Health Performance Standards Program (NPHPSP) has developed performance standards measurement instruments, based on the 10 "Essential Services of Public Health" that are being tested in several states. This article is a report on the face and content validity of the instrument designed for local public health systems. Judgments about the face validity of the standards were obtained in a survey of local public health systems that had used the instrument in a test state. The validity of each standard was addressed along the following dimensions: the importance of the standard as a measure of the Essential Service; its completeness as a measure; and its reasonableness for achievement. All standards for each Essential Service were then judged in terms of their completeness in measuring performance of that service. Respondents judged the standards to be highly valid measures of local public health system performance. Some respondents had reservations about whether standards related to "enforcing laws and regulations" were achievable. Holding local public health systems accountable for the activities of other agencies was a factor mentioned in conjunction with those standards. The NPHPSP standards have face and content validity for measuring local public health system performance. Further testing of their validity and reliability is continuing.

    Mental health clinicians can experience difficulties communicating diagnostic information to patients and their families/carers, especially about distressing psychiatric disorders such as schizophrenia. There is evidence for the effectiveness of communication skills training (CST) for improving diagnostic discussions, particularly in specialties such as oncology, but only limited evidence exists about CST for psychiatry. This study evaluated a CST program specifically developed for psychiatry residents called ComPsych that focuses on conveying diagnostic and prognostic information about schizophrenia. The ComPsych program consists of an introductory lecture, module booklets for trainees, and exemplary skills videos, followed by small group role-plays with simulated patients (SPs) led by a trained facilitator. A standardized patient assessment (SPA) was digitally recorded pre- and post-training with a SP using a standardized scenario in a time-limited (15 min) period. Recorded SPAs were independently rated using a validated coding system (ComSkil) to identify frequency of skills used in five skills categories (agenda setting, checking, questioning, information organization, and empathic communication). Thirty trainees (15 males and 15 females; median age = 32) undertaking their vocational specialty training in psychiatry participated in ComPsych training and pre- and post-ComPsych SPAs. Skills increased post-training for agenda setting (d = -0.82), while questioning skills (d = 0.56) decreased. There were no significant differences in any other skills grouping, although checking, information organization, and empathic communication skills tended to increase post-training. A dose effect was observed for agenda setting, with trainees who attended more CST sessions outperforming those attending fewer. Findings support the generalization and translation of ComPsych CST to psychiatry.

    Full Text Available Abstract Background Inadequate response to proton pump inhibitor (PPI therapy in patients with gastroesophageal reflux disease (GERD is reported in up to 40%. Patients with non erosive reflux disease (NERD have lower response rates compared to patients with erosive reflux disease (ERD; pH metry contributes to GERD diagnosis and is critical for proper diagnosis of NERD. Aim of the study was to assess the need for doubling esomeprazole standard dose (40 mg for 4 weeks in PPI naive patients with typical reflux symptoms and diagnosis of GERD based on endoscopy and 48 hours, wireless pH metry. Methods All patients underwent upper GI endoscopy. Symptoms were recorded with a structured questionnaire (RDQ and acid exposure was determined by 48 hours, wireless pH monitoring (BRAVO. In case of abnormal acid exposure, patients received a short term treatment with esomeprazole 40 mg q.d. for 4 weeks. If symptoms persisted, patients underwent a second pH metry on PPI and the dose was increased to 40 mg b.i.d. Results 31 consecutive patients with typical reflux symptoms underwent 48 hours pH monitoring. 22 patients (71% had abnormal acid exposure, 9 patients had normal pH metry (29%. Of the 9 patients with normal pH metry, 2 were found with erosive esophagitis and 7 without endoscopic abnormalities. 24 patients with documented GERD received esomeprazole treatment. 21 patients achieved complete symptom resolution with 40 mg q.d. after 4 weeks (88%. Only 2 patients required doubling the dose of esomeprazole for complete symptom resolution, 1 patient remained with symptoms. Conclusions Patients with typical reflux symptoms and abnormal acid exposure have a high response rate to standard dose esomeprazole regardless of whether they have ERD or NERD.

    Fuel cladding material plays important role as a primary structure under the high temperature, high pressure and neutron environment of nuclear power plant. According to this environment, cladding material can be experienced several type aging phenomena including the neutron irradiation embrittlement. On the other hand, although the early nuclear power plant was designed to fitting into the 40MWd/KgU burn-up, the currently power plant intends to go to the high burn-up range. In this case, the safety criteria which was established at low burn-up needs to conform the applicability at the high burn-up. In this study, the safety criteria of fuel cladding material was reviewed to assess the cladding material integrity, and the material characteristics of cladding were reviewed. The current LOCA criterial was also reviewed, and the basic study for re-establishment of LOCA criteria was performed. The time concept safety criteria was also discussed to prevent the breakaway oxidation. Through the this study, safety issues will be produced and be helpful for integrity insurance of nuclear fuel cladding material. This report is the final report.

    The era of school accountability and standards based reform (SBR) has brought many challenges and changes to Florida's public schools. It is important to understand any shifts in teachers' attitudes and to identify the changes teachers are making as they implement SBR. The study was designed to assess teachers' attitudes and perceptions of changes related to SBR and the Florida Comprehensive Assessment Test (FCAT) in middle school science programs in Florida. Survey questions sought to identify teacher perceptions of changes in curriculum, instruction and daily practice as schools documented and incorporated the Sunshine State Standards (SSS) for science and began focusing on preparing students for the science FCAT. The survey was distributed to 265 randomly selected middle school science teachers throughout the State of Florida. Seventy-six and ninety-two percent of teachers reported increased levels of stress as a result of SBR and the science FCAT, respectively. Eighty-six percent of teachers reported loss of autonomy and control over what goes on in their classrooms, and fifty-four percent of teachers reported loss of freedom and creativity regarding curriculum and lessons. Eighty-three percent of teachers believe that increased time spent on test preparation has come at the expense of other important curricular items. By contrast, only nineteen percent of teachers believe that the science FCAT has brought about improvement in curriculum, instruction and student learning in science. Yet, twenty-five percent of teachers believe that reform efforts will improve their school. An important finding is that teachers' attitudes toward reform efforts are strongly influenced by their attitudes toward the administration at their school. Teachers who receive more support from administrators have more positive attitudes toward all aspects of SBR and the science FCAT measured in this study. Although the majority of teachers reported negative attitudes toward the reform

    Full Text Available Functional MRI is increasingly recognized for its potential as a powerful new tool in clinical neuropsychology. This is likely due to the fact that, with some degree of innovation, it is possible to convert practically any familiar cognitive test into one that can be performed in the MRI scanning environment. However, like any assessment approach, meaningful interpretation of fMRI data for the purpose of patient evaluation crucially requires normative data derived from a sample of unimpaired persons, against which individual patients may be compared. Currently, no such normative data are available for any fMRI-based cognitive testing protocol. In this paper, we report the first of a series of fMRI-compatible cognitive assessment protocols, a matrix reasoning test (f-MRT, for which normative samples of functional activation have been collected from unimpaired control subjects and structured in a manner that makes individual patient evaluation possible in terms of familiar z-score distributions. Practical application of the f-MRT is demonstrated via a contrastive case-study of two individuals with cognitive impairment in which fMRI data identifies subtleties in patient deficits otherwise missed by conventional measures of performance.

    The large explosive eruption of Merapi volcano, Indonesia, in 2010 presented a key, and rare, opportunity to study the impacts of a major explosive eruption in a densely populated area. Pyroclastic density currents (PDCs) produced throughout the 2010 eruption were unusually destructive, causing near complete devastation across a 22 km2 swath of the densely populated southern flanks and casualties to the end of their runout at 15.5 km from the volcano. The majority (> 120) of the more than 200 fatalities occurred more than 12 km from the volcano, where many people were caught in PDCs as they were evacuating. The 2010 eruption (VEI 4) exhibited a range of PDC behaviour in a complex multi-stage event that marked a change in eruption behaviour at Merapi, being the first eruption of this magnitude and style since 1872. This shift in style may mark a change in regime, and so understanding the potential impact of such large explosive eruptions is essential for future risk-assessment at Merapi. We describe a new impact assessment methodology that allowed us to collect important empirical geological, damage and casualty information and reconstruct impact dynamics associated with the PDCs. In contrast to previous PDC impact studies, we combined remote, field, laboratory and GIS assessments and were able to enter the affected areas safely and before their disturbance by rains or human activity. By integrating the results of our geological, damage and medical studies, we could reconstruct the spatial and temporal dynamics of the PDCs and their main hazard characteristics. Our interdisciplinary methods and preliminary findings are discussed here. In the areas damaged by PDCs, we used empirical damage data and calculations of material and structural resistance to lateral force to estimate approximate dynamic pressures. Dynamic pressures associated with the 5 November paroxysm exceeded 15 kPa more than 6 km from source and rapidly attenuated over a distance of less than 1 km at

  4. System Energy Assessment (SEA, Defining a Standard Measure of EROI for Energy Businesses as Whole Systems

    Full Text Available A more objective method for measuring the energy needs of businesses, System Energy Assessment (SEA, measures the combined impacts of material supply chains and service supply chains, to assess businesses as whole self-managing net-energy systems. The method is demonstrated using a model Wind Farm, and defines a physical measure of their energy productivity for society (EROI-S, a ratio of total energy delivered to total energy expended. Energy use records for technology and proxy measures for clearly understood but not individually recorded energy uses for services are combined for a whole system estimate of consumption required for production. Current methods count only energy needs for technology. Business services outsource their own energy needs to operate, leaving no traceable record. That uncounted business energy demand is often 80% of the total, an amount of “dark energy” hidden from view, discovered by finding the average energy estimated needs for businesses far below the world average energy consumed per dollar of GDP. Presently for lack of information the energy needs of business services are counted to be “0”. Our default assumption is to treat them as “average”. The result is a hard measure of total business demand for energy services, a “Scope 4” energy use or GHG impact assessment. Counting recorded energy uses and discounting unrecorded ones misrepresents labor intensive work as highly energy efficient. The result confirms a similar finding by Hall et al. in 1981 [1]. We use exhaustive search for what a business needs to operate as a whole, tracing internal business relationships rather than energy data, to locate its natural physical boundary as a working unit, and so define a business as a physical rather than statistical subject of scientific study.

    Full Text Available Bangladesh is one of the vulnerable countries of the world for natural disasters. Drought is one of the common and severe calamities in Bangladesh that causes immense suffering to people in various ways. The present research has been carried out to examine the frequency of meteorological droughts in Bangladesh using the long-term rainfall data of 30 meteorological observatories covering the period of 1948–2011. The study uses the highly effective Standardized Precipitation Index (SPI for drought assessment in Bangladesh. By assessing the meteorological droughts and the history of meteorological droughts of Bangladesh, the spatial distributions of meteorological drought indices were also analysed. The spatial and temporal changes in meteorological drought and changes in different years based on different SPI month intervals were analysed. The results indicate that droughts were a normal and recurrent feature and it occurred more or less all over the country in virtually all climatic regions of the country. As meteorological drought depends on only rainfall received in an area, anomaly of rainfall is the main cause of drought. Bangladesh experienced drought in the years 1950, 1951, 1953, 1954, 1957, 1958, 1960, 1961, 1962, 1963, 1965, 1966, 1967 and 1971 before independence and after independence Bangladesh has experienced droughts in the years 1972, 1973, 1975, 1979, 1980, 1983, 1985, 1992, 1994, 1995, 2002, 2004, 2006, 2009 and 2011 during the period 1948–2011. The study indicated that Rajshahi and its surroundings, in the northern regions and Jessore and its surroundings areas, the island Bhola and surrounding regions, in the south-west region, were vulnerable. In the Sylhet division, except Srimongal, the areas were not vulnerable but the eastern southern sides of the districts Chittagong, Rangamati, Khagrachhari, Bandarban and Teknaf were vulnerable. In the central regions, the districts of Mymensingh and Faridpur were more vulnerable

    Animal models are often used to assess interventions that might improve fat grafting outcomes; however, there is great variability in the models. The authors sought to determine the predictive value of the immunocompromised mouse model for fat grafting so that experiments could be standardized and optimized. Human lipoaspirate injections at different volumes and time points were assessed in a nude mouse model and compared with control injections of nonviable fat. Volume retention and explant histologic score were compared. In a separate study, interanimal reproducibility was determined by implanting a highly consistent hydrogel and measuring variability in volume retention. Injection volume significantly affects adipose resorption kinetics at 6 and 12 weeks. Masson trichrome staining revealed that macrophages were unable to infiltrate large (1 ml) grafts, and oil cysts were not absorbed by 18 weeks, which interfered with interpretation of volume retention data. Nonviable tissue was resorbed when grafts were 0.3 ml, and quantification of graft histologic viability correlated well with graft retention at all study time points. Interanimal variability was measured to be 8.44 percent of the mean retention volume for small graft volumes. Human fat graft retention in the immunodeficient mouse correlates with graft viability in small, 0.3-ml-volume grafts. However, centralized oil cysts in nonviable 1.0-ml grafts were not resorbed by 18 weeks and thus volume measurements were confounded and not significantly different from viable samples. In addition, tissue injury scores increased in initially healthy fat grafts at 18 weeks, possibly because of a delayed immune reaction.

    Foods consist of a large number of different nutrients that are contained in a complex structure. The nature of the food structure and the nutrients therein (i.e., the food matrix) will determine the nutrient digestion and absorption, thereby altering the overall nutritional properties of the food. Thus, the food matrix may exhibit a different relation with health indicators compared to single nutrients studied in isolation. The evidence for a dairy matrix effect was presented and discussed by an expert panel at a closed workshop, and the following consensus was reached: 1) Current evidence does not support a positive association between intake of dairy products and risk of cardiovascular disease (i.e., stroke and coronary heart disease) and type 2 diabetes. In contrast, fermented dairy products, such as cheese and yogurt, generally show inverse associations. 2) Intervention studies have indicated that the metabolic effects of whole dairy may be different than those of single dairy constituents when considering the effects on body weight, cardiometabolic disease risk, and bone health. 3) Different dairy products seem to be distinctly linked to health effects and disease risk markers. 4) Different dairy structures and common processing methods may enhance interactions between nutrients in the dairy matrix, which may modify the metabolic effects of dairy consumption. 5) In conclusion, the nutritional values of dairy products should not be considered equivalent to their nutrient contents but, rather, be considered on the basis of the biofunctionality of the nutrients within dairy food structures. 6) Further research on the health effects of whole dairy foods is warranted alongside the more traditional approach of studying the health effects of single nutrients. Future diet assessments and recommendations should carefully consider the evidence of the effects of whole foods alongside the evidence of the effects of individual nutrients.

    Background and aims After a series of seminal works during the last decade of the 20th century, nitric oxide (NO) is now firmly placed in the pantheon of plant signals. Nitric oxide acts in plant–microbe interactions, responses to abiotic stress, stomatal regulation and a range of developmental processes. By considering the recent advances in plant NO biology, this review will highlight certain key aspects that require further attention. Scope and conclusions The following questions will be considered. While cytosolic nitrate reductase is an important source of NO, the contributions of other mechanisms, including a poorly defined arginine oxidizing activity, need to be characterized at the molecular level. Other oxidative pathways utilizing polyamine and hydroxylamine also need further attention. Nitric oxide action is dependent on its concentration and spatial generation patterns. However, no single technology currently available is able to provide accurate in planta measurements of spatio-temporal patterns of NO production. It is also the case that pharmaceutical NO donors are used in studies, sometimes with little consideration of the kinetics of NO production. We here include in planta assessments of NO production from diethylamine nitric oxide, S-nitrosoglutathione and sodium nitroprusside following infiltration of tobacco leaves, which could aid workers in their experiments. Further, based on current data it is difficult to define a bespoke plant NO signalling pathway, but rather NO appears to act as a modifier of other signalling pathways. Thus, early reports that NO signalling involves cGMP—as in animal systems—require revisiting. Finally, as plants are exposed to NO from a number of external sources, investigations into the control of NO scavenging by such as non-symbiotic haemoglobins and other sinks for NO should feature more highly. By crystallizing these questions the authors encourage their resolution through the concerted efforts of the plant

    The UK Water Industry currently generates approximately 800GWh pa of electrical energy from sewage sludge. Traditionally energy recovery from sewage sludge features Anaerobic Digestion (AD) with biogas utilisation in combined heat and power (CHP) systems. However, the industry is evolving and a number of developments that extract more energy from sludge are either being implemented or are nearing full scale demonstration. This study compared five technology configurations: 1 - conventional AD with CHP, 2 - Thermal Hydrolysis Process (THP) AD with CHP, 3 - THP AD with bio-methane grid injection, 4 - THP AD with CHP followed by drying of digested sludge for solid fuel production, 5 - THP AD followed by drying, pyrolysis of the digested sludge and use of the both the biogas and the pyrolysis gas in a CHP. The economic and environmental Life Cycle Assessment (LCA) found that both the post AD drying options performed well but the option used to create a solid fuel to displace coal (configuration 4) was the most sustainable solution economically and environmentally, closely followed by the pyrolysis configuration (5). Application of THP improves the financial and environmental performance compared with conventional AD. Producing bio-methane for grid injection (configuration 3) is attractive financially but has the worst environmental impact of all the scenarios, suggesting that the current UK financial incentive policy for bio-methane is not driving best environmental practice. It is clear that new and improving processes and technologies are enabling significant opportunities for further energy recovery from sludge; LCA provides tools for determining the best overall options for particular situations and allows innovation resources and investment to be focused accordingly.

Malignant gliomas have high morbidity and mortality. Even with optimal treatment, median survival is only 12–15 months for glioblastomas and 2–5 years for anaplastic gliomas. However, recent advances in imaging and quantitative analysis of image data have led to earlier diagnosis of tumors and tumor response to therapy, providing oncologists with a greater time window for therapy management. In addition, improved understanding of tumor biology, genetics, and resistance mechanisms has enhanced surgical techniques, chemotherapy methods, and radiotherapy administration. After proper diagnosis and institution of appropriate therapy, there is now a vital need for quantitative methods that can sensitively detect malignant glioma response to therapy at early follow-up times, when changes in management of nonresponders can have its greatest effect. Currently, response is largely evaluated by measuring magnetic resonance contrast and size change, but this approach does not take into account the key biologic steps that precede tumor size reduction. Molecular imaging is ideally suited to measuring early response by quantifying cellular metabolism, proliferation, and apoptosis, activities altered early in treatment. We expect that successful integration of quantitative imaging biomarker assessment into the early phase of clinical trials could provide a novel approach for testing new therapies

    Using a Standardized Clinical Assessment and Management Plan (SCAMP) for pediatric patients presenting to clinic with chest pain, we evaluated the cost impact associated with implementation of the care algorithm. Prior to introduction of the SCAMP, we analyzed charges for 406 patients with chest pain, seen in 2009, and predicted 21% reduction of overall charges had the SCAMP methodology been used. The SCAMP recommended an echocardiogram for history, examination, or ECG findings suggestive of a cardiac etiology for chest pain. Resource utilization was reviewed for 1517 patients (7-21 years) enrolled in the SCAMP from July 2010 to April 2014. Compared to the 2009 historic cohort, patients evaluated by the SCAMP had higher rates of exertional chest pain (45% vs 37%) and positive family history (5% vs 1%). The SCAMP cohort had fewer abnormal physical examination findings (1% vs 6%) and abnormal electrocardiograms (3% vs 5%). Echocardiogram use increased in the SCAMP cohort compared to the 2009 historic cohort (45% vs 41%), whereas all other ancillary testing was reduced: exercise stress testing (4% SCAMP vs 28% historic), Holter (4% vs 7%), event monitors (3% vs 10%), and MRI (1% vs 2%). Total charges were reduced by 22% ($822 625) by use of the Chest Pain SCAMP, despite a higher percentage of patients for whom echocardiogram was recommended compared to the historic cohort. The Chest Pain SCAMP effectively streamlines cardiac testing and reduces resource utilization. Further reductions can be made by algorithm refinement regarding echocardiograms for exertional symptoms. © 2017 Wiley Periodicals, Inc.

    A bacterial spore assay and a molecular DNA microarray method were compared for their ability to assess relative cleanliness in the context of bacterial abundance and diversity on spacecraft surfaces. Colony counts derived from the NASA standard spore assay were extremely low for spacecraft surfaces. However, the PhyloChip generation 3 (G3) DNA microarray resolved the genetic signatures of a highly diverse suite of microorganisms in the very same sample set. Samples completely devoid of cultivable spores were shown to harbor the DNA of more than 100 distinct microbial phylotypes. Furthermore, samples with higher numbers of cultivable spores did not necessarily give rise to a greater microbial diversity upon analysis with the DNA microarray. The findings of this study clearly demonstrated that there is not a statistically significant correlation between the cultivable spore counts obtained from a sample and the degree of bacterial diversity present. Based on these results, it can be stated that validated state-of-the-art molecular techniques, such as DNA microarrays, can be utilized in parallel with classical culture-based methods to further describe the cleanliness of spacecraft surfaces.

    Semantic verbal fluency (SVF) tests are widely used in clinical neuropsychology. We propose the standardization and clinical validation of a new SVF test based on the production of names of birds and articles of furniture (Birds and Articles of Furniture test-BAF). A sample of 268 subjects aged 40 years or more underwent the test. The clinical validation was conducted on subjects affected by amnesic Mild Cognitive Impairment (aMCI; N = 106), mild (N = 178), and moderate (N = 114) Alzheimer's disease (AD). The BAF total score was influenced by both age and education, whereas the single scores obtained on BAF were also influenced by gender. The percentage of subjects with pathological score on BAF increased from aMCI (19%) to mild (45.5%) and moderate (71.1%) AD, and receiver operating characteristic curves analysis showed that the BAF may be highly reliable in distinguishing aMCI and AD patients from healthy subjects. We also provide typicality norms for birds and articles of furniture that could be useful in the assessment of qualitative features of words produced in semantic fluency tests. The BAF test could be a valid and reliable tool in both clinical practice and research on subjects affected by cognitive impairment. © The Author 2016. Published by Oxford University Press.

    Full Text Available Abstract Ethiopia is facing rapid urbanization leading to overcrowding and the development of slums and informal settlements with poor waste management practices. Urban dwellers generally consume more resources than rural dwellers and so generate huge quantities of solid wastes. This study is focused on the overall assessment of the existing MSWM service of Gondar town. The overall objective of this study was assessing the current solid waste management service of Gondar town. Both primary and secondary sources were used to achieve the objectives. The analysis of this study was carried out using both qualitative and quantitative techniques. The findings of this study revealed that the present system of MSWM in Gondar town entirely relied on the municipality which provided the full range of waste collection transportation and disposal service. But the provision of this service is not kept in pace with the town solid waste generation. Based on the findings of this study the town households dominantly produced biodegradable solid wastes with generation rate of 0.21kgpersonday. This made the daily total solid waste generation of households to be 8140Kg. Together with other four solid waste sources the total daily solid waste generation of the town is about 11660 kg. So that MSWM of the town is found in very low status and spatial coverage. This poor status of MSWM is also intensified by three critical factors i.e poor institutional structure and capacity of Sanitation and beautification limited participation and contribution of stakeholders and poor households solid waste management practices. This study concluded that there should be sustainable solid waste management systems reuse recycle composting and incineration through awareness creation and training improvement of SB institutional structure and capacity and implementation of integrated MSWM approach which recognizes and comprises all stakeholders in the town.

    We aimed to compare the standardized central review of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT scans performed after induction therapy for follicular lymphoma (FL) in the PRIMA study (Salles et al., Lancet 377:42-51, 2011; Trotman et al., J Clin Oncol 29:3194-3200, 2011) to scan review at local centres. PET/CT scans were independently evaluated by two nuclear medicine physicians using the 2007 International Harmonization Project (IHP) criteria (Cheson et al., J Clin Oncol 25:579-586, 2007; Juweid et al., J Clin Oncol 25:571-578, 2007; Shankar et al., J Nucl Med 47:1059-1066, 2006) and Deauville 5-point scale (5PS) criteria (Meignan et al., Leuk Lymphoma 50:1257-1260, 2009; Meignan et al., Leuk Lymphoma 51:2171-2180, 2010; Barrington et al., Eur J Nucl Med Mol Imaging 37:1824-1833, 2010). PET/CT status was compared with prospectively recorded patient outcomes. Central evaluation was performed on 119 scans. At diagnosis, 58 of 59 were recorded as positive, with a mean maximum standardized uptake value (SUV{sub max}) of 11.7 (range 4.6-35.6). There was no significant association between baseline SUV{sub max} and progression-free survival (PFS). Sixty post-induction scans were interpreted using both the IHP criteria and 5PS. Post-induction PET-positive status failed to predict progression when applying the IHP criteria [p = 0.14; hazard ratio (HR) 1.9; 95 % confidence interval (CI) 0.8-4.6] or 5PS with a cut-off ≥3 (p = 0.12; HR 2.0; 95 % CI 0.8-4.7). However, when applying the 5PS with a cut-off ≥4, there was a significantly inferior 42-month PFS in PET-positive patients of 25.0 % (95 % CI 3.7-55.8 %) versus 61.4 % (95 % CI 45.4-74.1 %) in PET-negative patients (p = 0.01; HR 3.1; 95 % CI 1.2-7.8). The positive predictive value (PPV) of post-induction PET with this liver cut-off was 75 %. The 42-month PFS for patients remaining PET-positive by local assessment was 31.1 % (95 % CI 10.2-55.0 %) vs 64.6 % (95 % CI 47.0-77.6 %) for PET

    NO2 concentrations at the street level are a major concern for urban air quality in Europe and have been regulated under the EU Thematic Strategy on Air Pollution. Despite the legal requirements, limit values are exceeded at many monitoring stations with little or no improvement in recent years. In order to assess the effects of future emission control regulations on roadside NO2 concentrations, a downscaling module has been implemented in the GAINS integrated assessment model. The module follows a hybrid approach based on atmospheric dispersion calculations and observations from the AirBase European air quality database that are used to estimate site-specific parameters. Pollutant concentrations at every monitoring site with sufficient data coverage are disaggregated into contributions from regional background, urban increment, and local roadside increment. The future evolution of each contribution is assessed with a model of the appropriate scale: 28 × 28 km grid based on the EMEP Model for the regional background, 7 × 7 km urban increment based on the CHIMERE Chemistry Transport Model, and a chemical box model for the roadside increment. Thus, different emission scenarios and control options for long-range transport as well as regional and local emissions can be analysed. Observed concentrations and historical trends are well captured, in particular the differing NO2 and total NOx = NO + NO2 trends. Altogether, more than 1950 air quality monitoring stations in the EU are covered by the model, including more than 400 traffic stations and 70% of the critical stations. Together with its well-established bottom-up emission and dispersion calculation scheme, GAINS is thus able to bridge the scales from European-wide policies to impacts in street canyons. As an application of the model, we assess the evolution of attainment of NO2 limit values under current legislation until 2030. Strong improvements are expected with the introduction of the Euro 6 emission standard
