  15. Gasbuggy Site Assessment and Risk Evaluation

    Energy Technology Data Exchange (ETDEWEB)



    This report describes the geologic and hydrologic conditions and evaluates potential health risks to workers in the natural gas industry in the vicinity of the Gasbuggy, New Mexico, site, where the U.S. Atomic Energy Commission detonated an underground nuclear device in 1967. The 29-kiloton detonation took place 4,240 feet below ground surface and was designed to evaluate the use of a nuclear detonation to enhance natural gas production from the Pictured Cliffs Formation in the San Juan Basin, Rio Arriba County, New Mexico, on land administered by Carson National Forest. A site-specific conceptual model was developed based on current understanding of the hydrologic and geologic environment. This conceptual model was used for establishing plausible contaminant exposure scenarios, which were then evaluated for human health risk potential. The most mobile and, therefore, the most probable contaminant that could result in human exposure is tritium. Natural gas production wells were identified as having the greatest potential for bringing detonation-derived contaminants (tritium) to the ground surface in the form of tritiated produced water. Three exposure scenarios addressing potential contamination from gas wells were considered in the risk evaluation: a gas well worker during gas-well-drilling operations, a gas well worker performing routine maintenance, and a residential exposure. The residential exposure scenario was evaluated only for comparison; permanent residences on national forest lands at the Gasbuggy site are prohibited

  1. Wound assessment tools and nurses' needs: an evaluation study. (United States)

    Greatrex-White, Sheila; Moxey, Helen


    The purpose of this study was to ascertain how well different wound assessment tools meet the needs of nurses in carrying out general wound assessment and whether current tools are fit for purpose. The methodology employed was evaluation research. In order to conduct the evaluation, a literature review was undertaken to identify the criteria of an optimal wound assessment tool which would meet nurses' needs. Several freely available wound assessment tools were selected based on predetermined inclusion and exclusion criteria and an audit tool was developed to evaluate the selected tools based on how well they met the criteria of the optimal wound assessment tool. The results provide a measure of how well the selected wound assessment tools meet the criteria of the optimal wound assessment tool. No tool was identified which fulfilled all the criteria, but two (the Applied Wound Management tool and the National Wound Assessment Form) met the most criteria of the optimal tool and were therefore considered to best meet nurses' needs in wound assessment. The study provides a mechanism for the appraisal of wound assessment tools using a set of optimal criteria which could aid practitioners in their search for the best wound assessment tool. © 2013 The Authors.

  2. Assessment and evaluation in interprofessional education: exploring the field. (United States)

    Blue, Amy V; Chesluk, Benjamin J; Conforti, Lisa N; Holmboe, Eric S


    The practice of interprofessional education (IPE) is expanding rapidly in the United States and globally. The publication of competencies from the Interprofessional Education Collaborative (IPEC) was a significant step forward to recognize the importance of health professions collaboration and to guide institutions for educational program development. However, there remains substantial difficulty in implementation, as well as considerable variability in assessment of learners' interprofessional collaborative knowledge and skills and evaluation of IPE programs. We conducted a multi-methods project which included 20 key informant interviews, a literature review, and a meeting of an expert panel. Our goals were 1) explore the current field of IPE, 2) identify and disseminate best practices to institutions wishing to implement/augment IPE assessment and evaluation processes, 3) uncover gaps in current IPE assessment and evaluation practices, and 4) recommend next steps for the field. A small and growing literature indicates evidence of the effectiveness of IPE. A diverse collection of methods and tools are used to assess and evaluate IPE learners and programs; these are often used without an explicit program-evaluation framework. For the field to advance and to align with the demands of changing clinical care systems, robust assessment and evaluation methods, standardized use of common tools, and longitudinal assessment from diverse data streams are needed for IPE.

  8. Contexts for Assessment and Outcome Evaluation in Librarianship

    CERN Document Server

    Woodsworth, Anne


    Assessment and outcomes evaluation have become increasingly important in librarianship. Although initially used in educational contexts to measure student learning, the strategy has migrated to other contexts such as hiring, employee development, overall organizational and institutional successes, measuring the outcomes of projects and operational changes, and self assessment at the personal level. This growing emphasis is partly due to increasingly stringent requirements that funds are used effectively to improve services and operations. The current economic climate and retrenchments in non-p

  13. The assessment of safe nursing care: development and psychometric evaluation. (United States)

    Rashvand, Farnoosh; Ebadi, Abbas; Vaismoradi, Mojtaba; Salsali, Mahvash; Yekaninejad, Mir Saeed; Griffiths, Pauline; Sieloff, Christina


    To develop an instrument for the assessment of safe nursing care (ASNC) within the Iranian context and psychometrically evaluate its reliability and validity. There is a need for a valid and reliable instrument to assess how nurses employ the components of safe nursing care in clinical practice in non-Western countries. This methodological study was conducted in two phases: (1) a qualitative phase of instrument development, and (2) a quantitative phase of psychometric evaluation of the assessment of safe nursing care (ASNC). The instrument's content validity was assessed by experts in the field of safe nursing care. The reliability of this instrument was examined using internal consistency reliability and intra-rater reliability analysis. Exploratory factor analysis was then conducted to establish the instrument's initial construct validity. The instrument developed was a questionnaire with 32 items. The Cronbach's alpha of the scale was 0.92, and Intra-class Correlation Coefficient for intra-rater reliability was 0.78. Exploratory factor analysis resulted in a four-factor solution: (1) evaluation of nursing skills, (2) assessing the patient's psychological needs, (3) assessing the patient's physical need, and (4) Assessing nurses' teamwork. The four factors accounted for 63.54% of the observed variance. The ASNC can be applied to a wide variety of settings because of the broad range of methods utilised to generate items and domains, its comprehensive consideration of the principles of safe care, and its initial reliability and validity. The ASNC can help nurse managers assess whether clinical nurses are prepared to apply their safe care skills in clinical practice. It can also be used by clinical nurses to assess their own and peers' practice to detect potential areas for improvement in nursing care and help nurse managers with planning appropriate quality improvement programmes. © 2016 John Wiley & Sons Ltd.

  14. Evaluation of speech and language assessment approaches with bilingual children. (United States)

    De Lamo White, Caroline; Jin, Lixian


    British society is multicultural and multilingual, thus for many children English is not their main or only language. Speech and language therapists are required to assess accurately the speech and language skills of bilingual children if they are suspected of having a disorder. Cultural and linguistic diversity means that a more complex assessment procedure is needed and research suggests that bilingual children are at risk of misdiagnosis. Clinicians have identified a lack of suitable assessment instruments for use with this client group. This paper highlights the challenges of assessing bilingual children and reviews available speech and language assessment procedures and approaches for use with this client group. It evaluates different approaches for assessing bilingual children to identify approaches that may be more appropriate for carrying out assessments effectively. This review discusses and evaluates the efficacy of norm-referenced standardized measures, criterion-referenced measures, language-processing measures, dynamic assessment and a sociocultural approach. When all named procedures and approaches are compared, the sociocultural approach appears to hold the most promise for accurate assessment of bilingual children. Research suggests that language-processing measures are not effective indicators for identifying speech and language disorders in bilingual children, but further research is warranted. The sociocultural approach encompasses some of the other approaches discussed, including norm-referenced measures, criterion-referenced measures and dynamic assessment. The sociocultural approach enables the clinician to interpret results in the light of the child's linguistic and cultural background. In addition, combining approaches mitigates the weaknesses inherent in each approach. © 2011 Royal College of Speech and Language Therapists.

  17. The Radboud Dysarthria Assessment: Development and Clinimetric Evaluation. (United States)

    Knuijt, Simone; Kalf, Johanna G; van Engelen, Baziel G M; de Swart, Bert J M; Geurts, Alexander C H


    In the absence of an adequate dysarthria assessment in the Netherlands, we developed the Radboud Dysarthria Assessment (RDA). This article describes its development and clinimetric evaluation. Forty-three patients were assessed with the RDA. The recording forms were subjected to exploratory factor analysis and estimation of internal consistency. The self-evaluation questionnaire was tested for internal consistency and the severity scale for intra- and inter-rater reliability. Construct validity of the severity scale and questionnaire was determined by relating them to the Speech Handicap Index (SHI), Dutch sentence intelligibility assessment (NSVO-Z), and category fluency task. Exploratory factor analysis extracted 4 factors (articulation, resonance, phonation, respiration/prosody) yielding an explained variance of 70.3%. Each factor showed good internal consistency (Cronbach's α: 0.89-0.91). The self-evaluation questionnaire showed excellent internal consistency (Cronbach's α: 0.90). Intra-class correlation coefficients of the severity scale (0.85-0.86) showed good reliability. The severity scores and self-evaluation questionnaire correlated substantially to strongly with the SHI (rs = 0.40 and 0.80) and substantially with the NSVO-Z (rs = -0.65 and -0.52). The RDA is a valid and reliable tool, but further investigation is needed to demonstrate whether this instrument can successfully support speech-language therapists in correctly diagnosing the type of dysarthria. © 2018 S.

  1. Comparative assessment of nanomaterial definitions and safety evaluation considerations. (United States)

    Boverhof, Darrell R; Bramante, Christina M; Butala, John H; Clancy, Shaun F; Lafranconi, Mark; West, Jay; Gordon, Steve C


    Nanomaterials continue to bring promising advances to science and technology. In concert have come calls for increased regulatory oversight to ensure their appropriate identification and evaluation, which has led to extensive discussions about nanomaterial definitions. Numerous nanomaterial definitions have been proposed by government, industry, and standards organizations. We conducted a comprehensive comparative assessment of existing nanomaterial definitions put forward by governments to highlight their similarities and differences. We found that the size limits used in different definitions were inconsistent, as were considerations of other elements, including agglomerates and aggregates, distributional thresholds, novel properties, and solubility. Other important differences included consideration of number size distributions versus weight distributions and natural versus intentionally-manufactured materials. Overall, the definitions we compared were not in alignment, which may lead to inconsistent identification and evaluation of nanomaterials and could have adverse impacts on commerce and public perceptions of nanotechnology. We recommend a set of considerations that future discussions of nanomaterial definitions should consider for describing materials and assessing their potential for health and environmental impacts using risk-based approaches within existing assessment frameworks. Our intent is to initiate a dialogue aimed at achieving greater clarity in identifying those nanomaterials that may require additional evaluation, not to propose a formal definition.

  2. Evaluating Micrometeoroid and Orbital Debris Risk Assessments Using Anomaly Data (United States)

    Squire, Michael


    The accuracy of micrometeoroid and orbital debris (MMOD) risk assessments can be difficult to evaluate. A team from the National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) has completed a study that compared MMOD-related failures on operational satellites to predictions of how many of those failures should occur using NASA's TM"s MMOD risk assessment methodology and tools. The study team used the Poisson probability to quantify the degree of inconsistency between the predicted and reported numbers of failures. Many elements go into a risk assessment, and each of those elements represent a possible source of uncertainty or bias that will influence the end result. There are also challenges in obtaining accurate and useful data on MMOD-related failures.

  3. Assessment of Existing Data and Reports for System Evaluation (United States)

    Matolak, David W.; Skidmore, Trent A.


    This report describes work done as part of the Weather Datalink Research project grant. We describe the work done under Task 1 of this project: the assessment of the suitability of available reports and data for use in evaluation of candidate weather datalink systems, and the development of a performance parameter set for comparative system evaluation. It was found that existing data and reports are inadequate for a complete physical layer characterization, but that these reports provide a good foundation for system comparison. In addition, these reports also contain some information useful for evaluation at higher layers. The performance parameter list compiled can be viewed as near complete-additional investigations, both analytical/simulation and experimental, will likely result in additions and improvements to this list.

  4. Developing and evaluating distributions for probabilistic human exposure assessments

    Energy Technology Data Exchange (ETDEWEB)

    Maddalena, Randy L.; McKone, Thomas E.


    This report describes research carried out at the Lawrence Berkeley National Laboratory (LBNL) to assist the U. S. Environmental Protection Agency (EPA) in developing a consistent yet flexible approach for evaluating the inputs to probabilistic risk assessments. The U.S. EPA Office of Emergency and Remedial Response (OERR) recently released Volume 3 Part A of Risk Assessment Guidance for Superfund (RAGS), as an update to the existing two-volume set of RAGS. The update provides policy and technical guidance on performing probabilistic risk assessment (PRA). Consequently, EPA risk managers and decision-makers need to review and evaluate the adequacy of PRAs for supporting regulatory decisions. A critical part of evaluating a PRA is the problem of evaluating or judging the adequacy of input distributions PRA. Although the overarching theme of this report is the need to improve the ease and consistency of the regulatory review process, the specific objectives are presented in two parts. The objective of Part 1 is to develop a consistent yet flexible process for evaluating distributions in a PRA by identifying the critical attributes of an exposure factor distribution and discussing how these attributes relate to the task-specific adequacy of the input. This objective is carried out with emphasis on the perspective of a risk manager or decision-maker. The proposed evaluation procedure provides consistency to the review process without a loss of flexibility. As a result, the approach described in Part 1 provides an opportunity to apply a single review framework for all EPA regions and yet provide the regional risk manager with the flexibility to deal with site- and case-specific issues in the PRA process. However, as the number of inputs to a PRA increases, so does the complexity of the process for calculating, communicating and managing risk. As a result, there is increasing effort required of both the risk professionals performing the analysis and the risk manager

  5. Opening the Conversation on REU Assessment and Evaluation (United States)

    Pressley, S. N.; LeBeau, J. E.


    Project evaluation is a key component to ensuring success of any Research Experience for Undergraduates (REU) program. The Washington State University (WSU) Regional Atmospheric Chemistry: State-of-the-art Measurement and Modeling in the Pacific Northwest REU Site employs a mixed method approach to determine what is working well and what can use improvement (formative evaluation) and to determine impact and effectiveness of the project in reaching the stated goals (summative evaluation). Quantitative data is collected via a pre-/post-test measuring participants' research self-efficacy (RSE), motivation, background information, extent of socialization, and their interpretation of the value of the REU experience. Qualitative data is gathered through individual interviews with the REU students (at the beginning and end of the program) and faculty mentors (at the end). Beginning interviews focus on expectations for the REU program and student backgrounds. End interviews focus on student RSE development, interpretations of their experience, and the value of the experience. Faculty mentors are interviewed to gather insight on student performance in the program and perspectives on the overall success of the program in meeting the proposed goals. Students are provided an opportunity to comment on the strengths and weaknesses of workshops, providing critical feedback to the particular instructor and enabling the faculty to modify the workshop content and activities in future years. Finally, research results are evaluated during the final poster presentation, and faculty are interviewed to report on their perception of how each student learned and gained knowledge during the program. To evaluate the retention of students in engineering and science and identify chosen career paths, a longitudinal survey was created and it is administered via email each year. Many REU programs also employ the Undergraduate Research Students Self-Assessment (URSSA) online tool designed for

  7. Integrated Assessment Model Evaluation (United States)

    Smith, S. J.; Clarke, L.; Edmonds, J. A.; Weyant, J. P.


    Integrated assessment models of climate change (IAMs) are widely used to provide insights into the dynamics of the coupled human and socio-economic system, including emission mitigation analysis and the generation of future emission scenarios. Similar to the climate modeling community, the integrated assessment community has a two decade history of model inter-comparison, which has served as one of the primary venues for model evaluation and confirmation. While analysis of historical trends in the socio-economic system has long played a key role in diagnostics of future scenarios from IAMs, formal hindcast experiments are just now being contemplated as evaluation exercises. Some initial thoughts on setting up such IAM evaluation experiments are discussed. Socio-economic systems do not follow strict physical laws, which means that evaluation needs to take place in a context, unlike that of physical system models, in which there are few fixed, unchanging relationships. Of course strict validation of even earth system models is not possible (Oreskes etal 2004), a fact borne out by the inability of models to constrain the climate sensitivity. Energy-system models have also been grappling with some of the same questions over the last quarter century. For example, one of "the many questions in the energy field that are waiting for answers in the next 20 years" identified by Hans Landsberg in 1985 was "Will the price of oil resume its upward movement?" Of course we are still asking this question today. While, arguably, even fewer constraints apply to socio-economic systems, numerous historical trends and patterns have been identified, although often only in broad terms, that are used to guide the development of model components, parameter ranges, and scenario assumptions. IAM evaluation exercises are expected to provide useful information for interpreting model results and improving model behavior. A key step is the recognition of model boundaries, that is, what is inside

  10. Instrument development and evaluation for patient-related outcomes assessments

    Directory of Open Access Journals (Sweden)

    Farnik M


    Full Text Available Małgorzata Farnik, Władysław PierzchałaDepartment of Pneumonology, Silesian University of Medicine, Katowice, PolandAbstract: Patient-related outcomes measures could provide important information for the current state of the art in medical care and even have an impact on macrodecisions in the health care system. Patient-related outcomes were initially defined as subjective health indicators that allow disability and illness to be assessed, based on patient, caregiver, or physician self-reports. As illness involves psychological and behavioral complex processes of care, a multidisciplinary approach in measuring patient-reported outcomes should be recommended, such as quality of life questionnaires. Patient-related outcomes measures should correspond to specific clinical situations and bring opportunities to improve quality of care. Objective measurements enable quantitative data to be collected and analyzed. Depending on the aim of the research, investigators can use existing methods or develop new tools. This publication presents a methodology for developing patient-related outcomes measures, based on a multistage procedure. The proper definition of specific study objectives and the methodology of instrument development are crucial for successfully transferring the study concept. The model of instrument development is the process of starting from the preliminary phase and includes questionnaire design and scaling, pilot testing (cognitive debriefing, revision of the preliminary version, evaluation of the new tool, and implementation. Validation of the new instrument includes reliability, reproducibility, internal consistency, and responsiveness. The process of designing the new tool should involve a panel of experts, including clinicians, psychologists (preliminary phase, and statisticians (scale development and scoring, and patients (cognitive debriefing. Implementation of a new tool should be followed by evaluation study – assessment of

  12. The children's menu assessment: development, evaluation, and relevance of a tool for evaluating children's menus. (United States)

    Krukowski, Rebecca A; Eddings, Kenya; West, Delia Smith


    Restaurant foods represent a substantial portion of children's dietary intake, and consumption of foods away from home has been shown to contribute to excess adiposity. This descriptive study aimed to pilot-test and establish the reliability of a standardized and comprehensive assessment tool, the Children's Menu Assessment, for evaluating the restaurant food environment for children. The tool is an expansion of the Nutrition Environment Measures Survey-Restaurant. In 2009-2010, a randomly selected sample of 130 local and chain restaurants were chosen from within 20 miles of Little Rock, AR, to examine the availability of children's menus and to conduct initial calibration of the Children's Menu Assessment tool (final sample: n=46). Independent raters completed the Children's Menu Assessment in order to determine inter-rater reliability. Test-retest reliability was also examined. Inter-rater reliability was high: percent agreement was 97% and Spearman correlation was 0.90. Test-retest was also high: percent agreement was 91% and Spearman correlation was 0.96. Mean Children's Menu Assessment completion time was 14 minutes, 56 seconds ± 10 minutes, 21 seconds. Analysis of Children's Menu Assessment findings revealed that few healthier options were available on children's menus, and most menus did not provide parents with information for making healthy choices, including nutrition information or identification of healthier options. The Children's Menu Assessment tool allows for comprehensive, rapid measurement of the restaurant food environment for children with high inter-rater reliability. This tool has the potential to contribute to public health efforts to develop and evaluate targeted environmental interventions and/or policy changes regarding restaurant foods.

  13. Vaccine safety evaluation: Practical aspects in assessing benefits and risks. (United States)

    Di Pasquale, Alberta; Bonanni, Paolo; Garçon, Nathalie; Stanberry, Lawrence R; El-Hodhod, Mostafa; Tavares Da Silva, Fernanda


    Vaccines are different from most medicines in that they are administered to large and mostly healthy populations including infants and children, so there is a low tolerance for potential risks or side-effects. In addition, the long-term benefits of immunisation in reducing or eliminating infectious diseases may induce complacency due to the absence of cases. However, as demonstrated in recent measles outbreaks in Europe and United States, reappearance of the disease occurs as soon as vaccine coverage falls. Unfounded vaccine scares such as those associating the combined measles-mumps-rubella vaccine with autism, and whole-cell pertussis vaccines with encephalopathy, can also have massive impacts, resulting in reduced vaccine uptake and disease resurgence. The safety assessment of vaccines is exhaustive and continuous; beginning with non-clinical evaluation of their individual components in terms of purity, stability and sterility, continuing throughout the clinical development phase and entire duration of use of the vaccine; including post-approval. The breadth and depth of safety assessments conducted at multiple levels by a range of independent organizations increases confidence in the rigour with which any potential risks or side-effects are investigated and managed. Industry, regulatory agencies, academia, the medical community and the general public all play a role in monitoring vaccine safety. Within these stakeholder groups, the healthcare professional and vaccine provider have key roles in the prevention, identification, investigation and management of adverse events following immunisation (AEFI). Guidelines and algorithms aid in determining whether AEFI may have been caused by the vaccine, or whether it is coincidental to it. Healthcare providers are encouraged to rigorously investigate AEFIs and to report them via local reporting processes. The ultimate objective for all parties is to ensure vaccines have a favourable benefit-risk profile. Copyright

  16. Cystic fibrosis gene mutations: evaluation and assessment of disease severity

    Directory of Open Access Journals (Sweden)

    Vallières E


    Full Text Available Emilie Vallières, Joseph Stuart ElbornCystic Fibrosis and Airways Microbiology Research Group, Queens University Belfast, Belfast, UKAbstract: The cystic fibrosis transmembrane regulator (CFTR gene encodes an ion channel transporter, the CFTR protein. Since its identification in 1989, more than 1,900 sequence variants have been reported, resulting in a wide spectrum of clinical phenotypes. Cystic fibrosis (CF is associated with many CFTR mutants and there is a continuum of disease severity observed. Recent advances in fundamental research have increased our understanding of the consequent molecular defect arising from CF mutations. This knowledge has resulted in the development of CF-specific therapies, targeting either the genetic or the molecular defect. CF care, previously focused on symptom control, is therefore moving toward a "stratified" or "precision" therapeutic approach. This review outlines normal CFTR physiology, the proposed pathologic mechanism underlying CF associated-lung injury, classification of CF mutations, and the CF-specific therapies recently approved or in clinical trials.Keywords: cystic fibrosis, gene mutations, disease severity, evaluation, assessment

    White, Kimber L; Peachee, Vanessa L; Armstrong, Sarah R; Twerdok, Lorraine E; Clark, Charles R; Schreiner, Ceinwen A


    Female Sprague Dawley rats were exposed via inhalation to vapor condensates of either gasoline or gasoline combined with various fuel oxygenates to assess potential immunotoxicity of evaporative emissions. Test articles included vapor condensates prepared from "baseline gasoline" (BGVC), or gasoline combined with methyl tertiary butyl ether (G/MTBE), ethyl t-butyl ether (G/ETBE), t-amyl methyl ether (G/TAME), diisopropyl ether (G/DIPE), ethanol (G/EtOH), or t-butyl alcohol (G/TBA). Target concentrations were 0, 2000, 10,000 or 20,000mg/mg(3) administered for 6h/day, 5days/week for 4weeks. The antibody-forming cell (AFC) response to the T-dependent antigen, sheep erythrocyte (sRBC), was used to determine the effects of the gasoline vapor condensates on the humoral components of the immune system. Exposure to BGVC, G/MTBE, G/TAME, and G/TBA did not result in significant changes in the IgM AFC response to sRBC, when evaluated as either specific activity (AFC/10(6) spleen cells) or as total spleen activity (AFC/spleen). Exposure to G/EtOH and G/DIPE resulted in a dose-dependent decrease in the AFC response, reaching the level of statistical significance only at the high 20,000mg/m(3) level. Exposure to G/ETBE resulted in a statistically significant decrease in the AFC response at the middle (10,000mg/m(3)) and high (20,000mg/m(3)) exposure concentrations. Copyright © 2014 Elsevier Inc.

  19. Voice and Speech Quality Perception Assessment and Evaluation

    CERN Document Server

    Jekosch, Ute


    Foundations of Voice and Speech Quality Perception starts out with the fundamental question of: "How do listeners perceive voice and speech quality and how can these processes be modeled?" Any quantitative answers require measurements. This is natural for physical quantities but harder to imagine for perceptual measurands. This book approaches the problem by actually identifying major perceptual dimensions of voice and speech quality perception, defining units wherever possible and offering paradigms to position these dimensions into a structural skeleton of perceptual speech and voice quality. The emphasis is placed on voice and speech quality assessment of systems in artificial scenarios. Many scientific fields are involved. This book bridges the gap between two quite diverse fields, engineering and humanities, and establishes the new research area of Voice and Speech Quality Perception.

  20. Preanesthetic Evaluation and Assessment of Children with Down's Syndrome

    Directory of Open Access Journals (Sweden)

    Letterio B. Santamaria


    Full Text Available During preoperative evaluation for anesthesia in the Down patient, it is important to focus attention on the functional conditions of the patient and systems that frequently show anomalies. One of the challenges of evaluating pre-operative conditions and potential risks in the Down patient is the lack of a gold-standard evaluation score; cervical spine abnormalities, reduced dimensions and malformations of the airways, neurological changes, respiratory and cardiac disease, as well as endocrinological and metabolic alterations. We suggest, as a possible method of evaluation for patients with mental retardation and possible malformations, a new scale which takes the functional and mental conditions into account: the Sensorial, Psychological, Anatomical, Biological, Operational and Surgical (SPABOS Compliance Score.

  12. Redesigning and aligning assessment and evaluation for a federally funded math and science teacher educational program. (United States)

    Hardré, Patricia L; Slater, Janis; Nanny, Mark


    This paper examines the redesign of evaluation components for a teacher professional development project funded by the National Science Foundation. It focuses on aligning evaluation instrumentation and strategies with program goals, research goals and program evaluation best practices. The study identifies weaknesses in the original (year 1) program evaluation design and implementation, develops strategies and tracks changes for year 2 implementation, and then reports enhancement of findings and recommendations for year 3. It includes lessons learned about assessment and evaluation over the project lifespan, with implications for research and evaluation of a range of related programs. This study functions as a classic illustration of how critical it is to observe first principles of assessment and evaluation for funded programs, the risks that arise when they are ignored, and the benefits that accrue when they are systematically observed.

  13. Evaluating variability and uncertainty in radiological impact assessment using SYMBIOSE. (United States)

    Simon-Cornu, M; Beaugelin-Seiller, K; Boyer, P; Calmon, P; Garcia-Sanchez, L; Mourlon, C; Nicoulaud, V; Sy, M; Gonze, M A


    SYMBIOSE is a modelling platform that accounts for variability and uncertainty in radiological impact assessments, when simulating the environmental fate of radionuclides and assessing doses to human populations. The default database of SYMBIOSE is partly based on parameter values that are summarized within International Atomic Energy Agency (IAEA) documents. To characterize uncertainty on the transfer parameters, 331 Probability Distribution Functions (PDFs) were defined from the summary statistics provided within the IAEA documents (i.e. sample size, minimal and maximum values, arithmetic and geometric means, standard and geometric standard deviations) and are made available as spreadsheet files. The methods used to derive the PDFs without complete data sets, but merely the summary statistics, are presented. Then, a simple case-study illustrates the use of the database in a second-order Monte Carlo calculation, separating parametric uncertainty and inter-individual variability.

  18. Impact Assessment and Environmental Evaluation of Various Ammonia Production Processes (United States)

    Bicer, Yusuf; Dincer, Ibrahim; Vezina, Greg; Raso, Frank


    In the current study, conventional resources-based ammonia generation routes are comparatively studied through a comprehensive life cycle assessment. The selected ammonia generation options range from mostly used steam methane reforming to partial oxidation of heavy oil. The chosen ammonia synthesis process is the most common commercially available Haber-Bosch process. The essential energy input for the methods are used from various conventional resources such as coal, nuclear, natural gas and heavy oil. Using the life cycle assessment methodology, the environmental impacts of selected methods are identified and quantified from cradle to gate. The life cycle assessment outcomes of the conventional resources based ammonia production routes show that nuclear electrolysis-based ammonia generation method yields the lowest global warming and climate change impacts while the coal-based electrolysis options bring higher environmental problems. The calculated greenhouse gas emission from nuclear-based electrolysis is 0.48 kg CO2 equivalent while it is 13.6 kg CO2 per kg of ammonia for coal-based electrolysis method.

  20. Barriers and facilitators influencing ethical evaluation in health technology assessment. (United States)

    Assasi, Nazila; Schwartz, Lisa; Tarride, Jean-Eric; O'Reilly, Daria; Goeree, Ron


    The objective of this study was to explore barriers and facilitators influencing the integration of ethical considerations in health technology assessment (HTA). The study consisted of two complementary approaches: (a) a systematic review of the literature; and (b) an eighteen-item online survey that was distributed to fifty-six HTA agencies affiliated with the International Network of Agencies for Health Technology Assessment. The review identified twenty-six relevant articles. The most often cited barriers in the literature were: scarcity, heterogeneity and complexity of ethical analysis methods; challenges in translating ethical analysis results into knowledge that is useful for decision makers; and lack of organizational support in terms of required expertise, time and financial resources. The most frequently cited facilitators included: usage of value-based appraisal methods, stakeholder and public engagement, enhancement of practice guidelines, ethical expertise, and educational interventions. Representatives of twenty-six (46.5 percent) agencies from nineteen countries completed the survey. A median of 10 percent (interquartile range, 5 percent to 50 percent) of the HTA products produced by the agencies was reported to include an assessment of ethical aspects. The most commonly perceived barriers were: limited ethical knowledge and expertise, insufficient time and resources, and difficulties in finding ethical evidence or using ethical guidelines. Educational interventions, demand by policy makers, and involvement of ethicists in HTA were the most commonly perceived facilitators. Our results emphasize the importance of simplification of ethics methodology and development of good practice guidelines in HTA, as well as capacity building for engaging HTA practitioners in ethical analyses.

    Functional magnetic resonance imaging (fMRI) has been used to unveil how some foods and basic rewards are processed in the human brain. This study evaluated how resting state functional connectivity in regions of the human brain changed after differing qualities of beef steaks were consumed. Functional images of participants (n=8) were collected after eating high or low quality beef steaks on separate days, after consumption a sensory ballot was administered to evaluate consumers' perceptions of tenderness, juiciness, flavor, and overall liking. Imaging data showed that high quality steak samples resulted in greater functional connectivity to the striatum, medial orbitofrontal cortex, and insular cortex at various stages after consumption (P≤0.05). Furthermore, high quality steaks elicited higher sensory ballot scores for each palatability trait (P≤0.01). Together, these results suggest that resting state fMRI may be a useful tool for evaluating the neural process that follows positive sensory experiences such as the enjoyment of high quality beef steaks.

    O'Callaghan, James P; Daughtrey, Wayne C; Clark, Charles R; Schreiner, Ceinwen A; White, Russell


    Sprague-Dawley rats were exposed via inhalation to vapor condensates of either gasoline or gasoline combined with various fuel oxygenates to assess potential neurotoxicity of evaporative emissions. Test articles included vapor condensates prepared from "baseline gasoline" (BGVC), or gasoline combined with methyl tertiary butyl ether (G/MTBE), ethyl t-butyl ether (G/ETBE), t-amyl methyl ether (G/TAME), diisopropyl ether (G/DIPE), ethanol (G/EtOH), or t-butyl alcohol (G/TBA). Target concentrations were 0, 2000, 10,000 or 20,000mg/mg(3) and exposures were for 6h/day, 5days/week for 13weeks. The functional observation battery (FOB) with the addition of motor activity (MA) testing, hematoxylin and eosin staining of brain tissue sections, and brain regional analysis of glial fibrillary acidic protein (GFAP) were used to assess behavioral changes, traditional neuropathology and astrogliosis, respectively. FOB and MA data for all agents, except G/TBA, were negative. G/TBA behavioral effects resolved during recovery. Neuropathology was negative for all groups. Analyses of GFAP revealed increases in multiplebrain regions largely limited to males of the G/EtOH group, findings indicative of minor gliosis, most significantly in the cerebellum. Small changes (both increases and decreases) in GFAP were observed for other test agents but effects were not consistent across sex, brain region or exposure concentration.

  5. Practical evaluation procedure to assess and remediate speech perception skills. (United States)

    Vergara, K C; Miskiel, L W; Oller, D K; Eilers, R E


    The University of Miami/Dade County Public Schools Model Program for the Deaf and Hard of Hearing is a research and training effort dedicated to the utilization of sensory aids including hearing aids, tactual vocoders, and cochlear implants. The program's teachers and clinicians follow the Miami Cochlear Implant, Auditory, and Tactile Skills (CHATS) Curriculum for the development of individualized speech perception and production goals. A series of peech perception tests has been used for the past five years to evaluate the children's progress. The test battery, administered at six month intervals, is extensive and impractical for school clinicians and teachers to administer to their students. To assist teachers and clinicians in the process of selecting appropriate goals and objectives for sensory aid training, a speech perception test has been developed to accompany the curriculum. This paper includes a discussion of the test design as it correlates with the curriculum.

  7. Curriculum Evaluation and Assessment of Multicultural Genetic Counselor Education. (United States)

    Wang, V O


    Multicultural competence in genetic counseling integrates racial-cultural knowledge, awareness, and skills into clinical interventions and research practices. Researchers and educators often cite racial-cultural factors as obstacles for visible racial-cultural people seeking help. However, the professional's unfamiliarity of how his or her own racial-cultural group affiliations are influenced by the history of discrimination and oppression coupled with their lack of self-understanding of racial-cultural issues for him- or herself has also limited the effectiveness of genetic counseling. The purpose of this study is to evaluate the effectiveness of the Handbook of Cross-Cultural Genetic Counseling, a multicultural curriculum developed for genetic counselor education for increasing multicultural counseling competence. The multicultural curriculum was evaluated for its effectiveness of increasing multicultural counseling competence using a nonequivalent control group design. A participant's multicultural counseling competence was hypothesized to increase after being taught the curriculum. The curriculum was effective for increasing multicultural counseling competence. Additionally, achieved multicultural counseling competence was not influenced by when the curriculum was taught. Trend analyses measuring the longitudinal impact of the curriculum on multicultural competence were significant. Implications of the results are discussed.

    Full Text Available Learner self-assessment of linguistic performance has been lately used due to its potential to activate the process of learning. Self-assessment raises learner awareness of language use and leads to developing learner responsibility and autonomy. However, usefulness of self-assessment for evaluation purposes has been scarcely researched. This paper examines some aspects of learners’ self-assessment for evaluation purposes at tertiary level. Research focuses on self-assessment of English for Specific Purposes (ESP vocabulary and some language skills relevant for vocabulary retention. Data on learner self-assessment are compared to actual results in tests. The analysis provided points to importance of self-evaluation in language acquisition and suggests practical implications of self-assessment for evaluation.

    Trujillo, Jennifer M; DiVall, Margarita V; Barr, Judith; Gonyeau, Michael; Van Amburgh, Jenny A; Matthews, S James; Qualters, Donna


    To develop a formalized, comprehensive, peer-driven teaching assessment program and a valid and reliable assessment tool. A volunteer taskforce was formed and a peer-assessment program was developed using a multistep, sequential approach and the Peer Observation and Evaluation Tool (POET). A pilot study was conducted to evaluate the efficiency and practicality of the process and to establish interrater reliability of the tool. Intra-class correlation coefficients (ICC) were calculated. ICCs for 8 separate lectures evaluated by 2-3 observers ranged from 0.66 to 0.97, indicating good interrater reliability of the tool. Our peer assessment program for large classroom teaching, which includes a valid and reliable evaluation tool, is comprehensive, feasible, and can be adopted by other schools of pharmacy.

    Full Text Available Ron Goeree1,2, Jing He1,2, Daria O'Reilly1,2, Jean-Eric Tarride1,2, Feng Xie1,2, Morgan Lim1,2, Natasha Burke1,21Programs for Assessment of Technology in Health (PATH Research Institute, St Joseph's Healthcare Hamilton, ON, Canada; 2Department of Clinical Epidemiology and Biostatistics, McMaster University, Hamilton, ON, CanadaBackground: Health technology assessments (HTA generally, and economic evaluations (EE more specifically, have become an integral part of health care decision making around the world. However, these assessments are time consuming and expensive to conduct. Evaluation resources are scarce and therefore priorities need to be set for these assessments and the ability to use information from one country or region in another (geographic transferability is an increasingly important consideration.Objectives: To review the existing approaches, systems, and tools for assessing the geographic transferability potential or guiding the conduct of transferring HTAs and EEs.Methods: A systematic literature review was conducted of several databases, supplemented with web searching, hand searching of journals, and bibliographic searching of identified articles. Systems, tools, checklists, and flow charts to assess, evaluate, or guide the conduct of transferability of HTAs and EEs were identified.Results: Of 282 references identified, 27 articles were reviewed in full text and of these, seven proposed unique systems, tools, checklists, or flow charts specifically for geographic transferability. All of the seven articles identified a checklist of transferability factors to consider, and most articles identified a subset of 'critical' factors for assessing transferability potential. Most of these critical factors related to study quality, transparency of methods, the level of reporting of methods and results, and the applicability of the treatment comparators to the target country. Some authors proposed a sequenced flow chart type approach

  16. Assessment of SOAP note evaluation tools in colleges and schools of pharmacy. (United States)

    Sando, Karen R; Skoy, Elizabeth; Bradley, Courtney; Frenzel, Jeanne; Kirwin, Jennifer; Urteaga, Elizabeth


    To describe current methods used to assess SOAP notes in colleges and schools of pharmacy. Members of the American Association of Colleges of Pharmacy Laboratory Instructors Special Interest Group were invited to share assessment tools for SOAP notes. Content of submissions was evaluated to characterize overall qualities and how the tools assessed subjective, objective, assessment, and plan information. Thirty-nine assessment tools from 25 schools were evaluated. Twenty-nine (74%) of the tools were rubrics and ten (26%) were checklists. All rubrics included analytic scoring elements, while two (7%) were mixed with holistic and analytic scoring elements. A majority of the rubrics (35%) used a four-item rating scale. Substantial variability existed in how tools evaluated subjective and objective sections. All tools included problem identification in the assessment section. Other assessment items included goals (82%) and rationale (69%). Seventy-seven percent assessed drug therapy; however, only 33% assessed non-drug therapy. Other plan items included education (59%) and follow-up (90%). There is a great deal of variation in the specific elements used to evaluate SOAP notes in colleges and schools of pharmacy. Improved consistency in assessment methods to evaluate SOAP notes may better prepare students to produce standardized documentation when entering practice. Copyright © 2017 Elsevier Inc.

  17. Determinants and Functions of Standardized Assessment Use Among School Mental Health Clinicians: A Mixed Methods Evaluation. (United States)

    Lyon, Aaron R; Ludwig, Kristy; Wasse, Jessica Knaster; Bergstrom, Alex; Hendrix, Ethan; McCauley, Elizabeth


    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.

  19. Assessing children's disaster reactions and mental health needs: screening and clinical evaluation. (United States)

    Pfefferbaum, Betty; North, Carol S


    To present a framework for assessing children's disaster reactions and mental health needs. We reviewed the relevant literature and clinical experience to identify information on assessment approaches in children and to construct an assessment framework based on disaster exposure. Child disaster mental health assessment includes 2 components-screening and clinical evaluation-but these have not been fully explicated or distinguished in the literature. Screening can be used to assess large numbers of children across exposure groups. Clinical evaluation is appropriate for children who are directly exposed to a disaster, for those whose family members and (or) close associates are directly exposed, and for those who are identified through screening as being at risk for psychiatric disturbance. Clinical evaluation includes a full diagnostic assessment (posttraumatic stress disorder and other disorders) with the goals of identifying psychopathology, determining the need for clinical care, and guiding intervention planning and referral. Children with psychiatric conditions should be referred to treatment, while those with psychological distress but without psychiatric illness may benefit from psychosocial interventions. Screening is appropriate to identify children at risk for psychiatric disturbance who will need further evaluation to determine diagnosis. Screening should not be used to dictate treatment decisions. Children who screen positive for psychiatric risk should receive a full clinical evaluation. Children determined to be suffering from psychiatric disorders should receive, or be referred for, formal treatment. Children without psychiatric disorders may benefit from psychosocial interventions.

  1. LNG Safety Assessment Evaluation Methods

    Energy Technology Data Exchange (ETDEWEB)

    Muna, Alice Baca [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States); LaFleur, Angela Christine [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)


    Sandia National Laboratories evaluated published safety assessment methods across a variety of industries including Liquefied Natural Gas (LNG), hydrogen, land and marine transportation, as well as the US Department of Defense (DOD). All the methods were evaluated for their potential applicability for use in the LNG railroad application. After reviewing the documents included in this report, as well as others not included because of repetition, the Department of Energy (DOE) Hydrogen Safety Plan Checklist is most suitable to be adapted to the LNG railroad application. This report was developed to survey industries related to rail transportation for methodologies and tools that can be used by the FRA to review and evaluate safety assessments submitted by the railroad industry as a part of their implementation plans for liquefied or compressed natural gas storage ( on-board or tender) and engine fueling delivery systems. The main sections of this report provide an overview of various methods found during this survey. In most cases, the reference document is quoted directly. The final section provides discussion and a recommendation for the most appropriate methodology that will allow efficient and consistent evaluations to be made. The DOE Hydrogen Safety Plan Checklist was then revised to adapt it as a methodology for the Federal Railroad Administration’s use in evaluating safety plans submitted by the railroad industry.

  2. Financial and testamentary capacity evaluations: procedures and assessment instruments underneath a functional approach. (United States)

    Sousa, Liliana B; Simões, Mário R; Firmino, Horácio; Peisah, Carmelle


    Mental health professionals are frequently involved in mental capacity determinations. However, there is a lack of specific measures and well-defined procedures for these evaluations. The main purpose of this paper is to provide a review of financial and testamentary capacity evaluation procedures, including not only the traditional neuropsychological and functional assessment but also the more recently developed forensic assessment instruments (FAIs), which have been developed to provide a specialized answer to legal systems regarding civil competencies. Here the main guidelines, papers, and other references are reviewed in order to achieve a complete and comprehensive selection of instruments used in the assessment of financial and testamentary capacity. Although some specific measures for financial abilities have been developed recently, the same is not true for testamentary capacity. Here are presented several instruments or methodologies for assessing financial and testamentary capacity, including neuropsychological assessment, functional assessment scales, performance based functional assessment instruments, and specific FAIs. FAIs are the only specific instruments intended to provide a specific and direct answer to the assessment of financial capacity based on legal systems. Considering the need to move from a diagnostic to a functional approach in financial and testamentary capacity evaluations, it is essential to consider both general functional examination as well as cognitive functioning.

    Wang, Sheng-qiang; Bai, Ya-Ping; Wang, Zi-chen


    To establish perfect criteria for clinical evaluation and assessment of therapeutic effects of peripheral facial paralysis. With reference to relative evaluating criteria, and in combination with self-characteristics of TCM and functional characteristics of facial nerves, and via clinical repeated investigation and control evaluation, put forward a scale for peripheral facial nerve rating, criteria for facial nerve grading, criteria of syndrome types and criteria of assessment of therapeutic effects. Clinical preliminary determination indicated that the assessment contents were characterized by rational reference, convenience and objectiveness. The program can used as criteria for clinical evaluation and assessment of therapeutic effects, but it needs support of clinical effectiveness and determination of confidence, and multi-central studies.

  5. The Geocybernetic Assessment Matrix (GAM) — A new assessment tool for evaluating the level and nature of sustainability or unsustainability

    Energy Technology Data Exchange (ETDEWEB)

    Phillips, Jason, E-mail:


    Evaluating sustainability from EIA-based assessments has been problematic at best. This is due to the use of reductionist and qualitative approaches which is dependent upon the perspective of the assessor(s). Therefore, a more rigorous and holistic approach is required to evaluate sustainability in a more consistent way. In this paper, a matrix-based methodology in order to assess the indicated level and nature of sustainability for any project, policy, indicators, legislation, regulation, or other framework is described. The Geocybernetic Assessment Matrix (GAM) is designed to evaluate the level and nature of sustainability or unsustainability occurring in respect the fundamental and complex geocybernetic paradigms. The GAM method is described in detail in respect to the theory behind it and the methodology. The GAM is then demonstrated using an appropriate case study — Part 1 of the UK Climate Change Act (2008) concerning carbon budgets and targets. The results indicate that the Part 1 of Act may not achieve the desired goals in contributing towards sustainable development through the stated mechanisms for carbon budgets and targets. The paper then discusses the broader context of the GAM with respect to the core themes evident in the development and application of the GAM of: sustainability science; sustainability assessment; application value of the GAM; and future research and development. - Highlights: • A new assessment tool called the Geocybernetic Assessment Matrix (GAM) described. • GAM evaluates the level and nature of sustainability or unsustainability. • GAM demonstrated by application to Part 1 of the UK Climate Change Act (CCA). • Part 1 of CCA has significant flaws in achieving a sustainable pathway. • GAM offers a potentially useful tool for quantitatively evaluating sustainability.

  7. Assessing Student Understanding of the "New Biology": Development and Evaluation of a Criterion-Referenced Genomics and Bioinformatics Assessment (United States)

    Campbell, Chad Edward

    Over the past decade, hundreds of studies have introduced genomics and bioinformatics (GB) curricula and laboratory activities at the undergraduate level. While these publications have facilitated the teaching and learning of cutting-edge content, there has yet to be an evaluation of these assessment tools to determine if they are meeting the quality control benchmarks set forth by the educational research community. An analysis of these assessment tools indicated that valid and reliable inferences about student learning. To remedy this situation the development of a robust GB assessment aligned with the quality control benchmarks was undertaken in order to ensure evidence-based evaluation of student learning outcomes. Content validity is a central piece of construct validity, and it must be used to guide instrument and item development. This study reports on: (1) the correspondence of content validity evidence gathered from independent sources; (2) the process of item development using this evidence; (3) the results from a pilot administration of the assessment; (4) the subsequent modification of the assessment based on the pilot administration results and; (5) the results from the second administration of the assessment. Twenty-nine different subtopics within GB (Appendix B: Genomics and Bioinformatics Expert Survey) were developed based on preliminary GB textbook analyses. These subtopics were analyzed using two methods designed to gather content validity evidence: (1) a survey of GB experts (n=61) and (2) a detailed content analyses of GB textbooks (n=6). By including only the subtopics that were shown to have robust support across these sources, 22 GB subtopics were established for inclusion in the assessment. An expert panel subsequently developed, evaluated, and revised two multiple-choice items to align with each of the 22 subtopics, producing a final item pool of 44 items. These items were piloted with student samples of varying content exposure levels

  8. Utility of factor analysis in optimization of resident assessment and faculty evaluation. (United States)

    Teman, Nicholas R; Minter, Rebecca M; Kasten, Steven J


    Increasing focus on more granular assessment in medical education has led to more lengthy instruments, with concern that the increased complexity undermines the utility of these tools. This study evaluated the relative contribution of individual questions in an assessment of resident performance and a faculty performance evaluation by residents. The authors performed factor analysis on the individual items in the resident assessment instrument (3,009 assessments of 71 residents) and faculty evaluations (7,328 evaluations of 61 faculty) collected from 2006 to 2012. Factor analysis of the resident assessment tool revealed that 1 component was responsible for 96.6% of the variance. This component encompassed each question from the assessment form, and could also be termed "overall resident competency." Factor analysis of the attending evaluation form revealed 2 unique components, representing "clinical care" and "interpersonal skills," which accounted for 89.9% of variance. Three components accounted for 90% to 97% of the observed variance in our analysis. Factor analysis represents a useful strategy for analyzing the utility of data obtained from individual items in the assessment and evaluation instruments. Copyright © 2015 Elsevier Inc.

  20. Performance Evaluation and Requirements Assessment for Gravity Gradient Referenced Navigation

    Directory of Open Access Journals (Sweden)

    Jisun Lee


    Full Text Available In this study, simulation tests for gravity gradient referenced navigation (GGRN are conducted to verify the effects of various factors such as database (DB and sensor errors, flight altitude, DB resolution, initial errors, and measurement update rates on the navigation performance. Based on the simulation results, requirements for GGRN are established for position determination with certain target accuracies. It is found that DB and sensor errors and flight altitude have strong effects on the navigation performance. In particular, a DB and sensor with accuracies of 0.1 E and 0.01 E, respectively, are required to determine the position more accurately than or at a level similar to the navigation performance of terrain referenced navigation (TRN. In most cases, the horizontal position error of GGRN is less than 100 m. However, the navigation performance of GGRN is similar to or worse than that of a pure inertial navigation system when the DB and sensor errors are 3 E or 5 E each and the flight altitude is 3000 m. Considering that the accuracy of currently available gradiometers is about 3 E or 5 E, GGRN does not show much advantage over TRN at present. However, GGRN is expected to exhibit much better performance in the near future when accurate DBs and gravity gradiometer are available.

    Srivastava D


    Full Text Available Background: Hyperuricaemia has been reported to be in normal healthy population. Method: Serum uric acid was estimated in 542 vegetarian healthy persons complaining of pain in the joint and in different musculoskeletal problems. Results: Four hundred cases (73.80 % were having uric acid level above 5 mg %. The mean uric acid level was found to be 6.16% + 3.08 percent. Increased uric acid level was not found to be associated with the age. Conclusion: The rise in the uric acid does not merely indicate gout but derails the normal physiology in some musculoskeletal sites and produces symptoms. Its association with hypertriglyceridaemia and hypertension is also alarming .It is found also closely related to the high alcohol intake, diuretic drugs, hypothyroidism and obesity. Hyperuricaemia is more than what is as usually believed and needs investigation. The possible cause of the hyperuricaemia in normal healthy individuals is discussed.

    Wendt, Kim; Crilly, Julia; May, Chris; Bates, Kym; Saxena, Rakhee


    Background Complications in early pregnancy, such as threatened or actual miscarriage is a common occurrence resulting in many women presenting to the emergency department (ED). Early pregnancy service delivery models described in the literature vary in terms of approach, setting and outcomes. Our objective was to determine outcomes of women who presented to an Australian regional ED with diagnoses consistent with early pregnancy complications following the implementation of an early pregnancy assessment service (EPAS) and early pregnancy assessment protocol (EPAP) in July 2011. Methods A descriptive, comparative (6 months before and after) study was undertaken. Data were extracted from the hospital ED information system and medical healthcare records. Outcome measures included: time to see a clinician, ED length of stay, admission rate, re-presentation rate, hospital admission and types of pathology tests ordered. Results Over the 12 -month period, 584 ED presentations were made to the ED with complications of early pregnancy (268 PRE and 316 POST EPAS–EPAP). Outcomes that improved statistically and clinically following implementation included: time to see a clinician (decreased by 6 min from 35 to 29 min), admission rate (decreased 6% from 14.5% to 8.5%), increase in β-human chorionic gonadotrophin ordering by 10% (up to 80% POST), increase in ultrasound (USS) performed by 10% (up to 73% POST) and increase in pain score documentation by 23% (up to 36% POST). Conclusions The results indicate that patient and service delivery improvements can be achieved following the implementation of targeted service delivery models such as EPAS and EPAP in the ED.

  18. Multiple flood vulnerability assessment approach based on fuzzy comprehensive evaluation method and coordinated development degree model. (United States)

    Yang, Weichao; Xu, Kui; Lian, Jijian; Bin, Lingling; Ma, Chao


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

  20. Follow-up Assessment of a Faculty Peer Observation and Evaluation Program (United States)

    Barr, Judith; Gonyeau, Michael; Matthews, S. James; Van Amburgh, Jenny; Qualters, Donna; Trujillo, Jennifer


    Objective. To assess a previously described peer observation and evaluation program 2 years after implementation. Methods. An pre-implementation survey assessed faculty needs and attitudes related to peer evaluation. Two years after implementation, the survey was repeated and additional questions asked regarding adherence to peer observation and evaluation policies and procedures, feedback received, and impact on teaching. Results. Faculty attitudes towards peer evaluation stayed the same or improved post-implementation. Adherence to the initial 3 steps of the process was high (100%, 100%, and 94%, respectively); however, step 4, which required a final discussion after student assessments were finished, was completed by only 47% of the respondents. All faculty members reported receiving a balance of positive and constructive feedback; 78% agreed that peer observation and evaluation gave them concrete suggestions for improving their teaching; and 89% felt that the benefits of peer observation and evaluation outweighed the effort of participating. Conclusions. Faculty members adhered to the policies and procedures of peer observation and evaluation and found peer feedback was beneficial. PMID:22611270

  1. A Methodological Approach to User Evaluation and Assessment of a Virtual Environment Hangout

    Directory of Open Access Journals (Sweden)

    Marco Pasin


    Full Text Available Innovation in virtual reality and motion sensing devices is pushing the development of virtual communication platforms towards completely immersive scenarios, which require full user interaction and create complex sensory experiences. This evolution influences user experiences and creates new paradigms for interaction, leading to an increased importance of user evaluation and assessment on new systems interfaces and usability, to validate platform design and development from the users’ point of view. The REVERIE research project aims to develop a virtual environment service for realistic inter-personal interaction. This paper describes the design challenges faced during the development process of user interfaces and the adopted methodological approach to user evaluation and assessment.

    Although there is increased awareness of patient and public involvement (PPI) among health technology assessment (HTA) organizations, evaluations of PPI initiatives are relatively scarce. Our objective as members of Health Technology Assessment International's (HTAi's) Patient and Citizen Involvement Group (PCIG) was to advance understanding of the range of evaluation strategies adopted by HTA organizations and their potential usefulness. In March 2016, a survey was sent to fifty-four HTA organizations through the International Network of Agencies for Health Technology Assessment (INAHTA) and contacts of members of HTAi's PCIG. Respondents were asked about their organizational structure; how patients and members of the public are involved; whether and how PPI initiatives have been evaluated, and, if so, which facilitators and challenges to evaluation were found and how results were used and disseminated. Fifteen (n = 15) programs from twelve countries responded (response rate 27.8 percent) that involved patients (14/15) and members of the public (10/15) in HTA activities. Seven programs evaluated their PPI activities, including participant satisfaction (5/7), process (5/7) and impact evaluations (4/7). Evaluation results were used to improve PPI activities, identify education and training needs, and direct strategic priorities. Facilitators and challenges revolved around the need for stakeholder buy-in, sufficient resources, senior leadership, and including patients in evaluations. A small but diverse set of HTA organizations evaluate their PPI activities using a range of strategies that reflect the range of rationales and approaches to PPI in HTA. It will be important for HTA organizations to draw on evaluation theories and methods.

  3. Evaluation model for developing, implementing, and assessing conservation education programs: Examples from Belize and Costa Rica (United States)

    Jacobson, Susan K.


    Evaluation of conservation education programs can: (1) provide accountability in demonstrating a program's worth, (2) offer an opportunity for receiving feedback and improving programs, (3) further our understanding of the process of program development, and (4) promote conservation education by substantiating claims about its benefits. The Planning-Process-Product systems evaluation model provides feedback needed for making decisions about the development, implementation, and outcome of a program. Planning evaluation was useful in assessing the needs, goals, opportunities, and constraints of a number of programs in Costa Rica and Belize, such as a forestry education project and a zoo outreach program. It provided a basis for making planning decisions incorporating specific objectives, such as the reforestation of a region or a change in knowledge and attitudes in program participants. Process evaluation provided a Costa Rican sustainable development program with feedback during its implementation and enabled it to modify and improve its newsletter for local farmers and its ecology classes for school children. Product evaluation assessed project accomplishments, such as the 700,000 raised by the Children's Rainforest group and the 20 miles of riparian land under conservation management as part of the Belize Community Baboon Sanctuary project. Outcomes are compared with the programs original monetary or land management objectives to determine the success of the programs and to provide feedback for improvement.

  4. Technological pedagogical content knowledge of prospective mathematics teachers regarding evaluation and assessment

    Directory of Open Access Journals (Sweden)

    Ercan Atasoy


    Full Text Available The ‘technology integrated assessment process’ is an innovative method to capture and determine students’ understanding of mathematics. This assessment process is claimed to provide a singular dynamism for teaching and learning activities and it is also claimed to be of the most important elements of instruction in the educational system. In this sense, this study aims to investigate technological pedagogical content knowledge (TPACK of prospective mathematics teachers regarding the ‘evaluation’ and ‘assessment’ process. To achieve this aim, the method of qualitative research was conducted with 20 teachers. Video records and lesson plans were collected and a Mathematics Teacher TPACK Development Model was utilized to reveal themes and key features of the data. The findings revealed that, although the majority of teachers stated that they would like to use technology-integrated tools in the assessment and evaluation processes, they strongly preferred to use traditional assessment and evaluation techniques, such as pen and paper activities, multiple-choice questions in virtual environments, etc. Hence, the evidence suggests that teachers would be unable to use appropriately the technological assessment process in order to reveal students’ understanding of mathematics. As seen from the teachers’ lectures, they perceived that technology would be suitable for evaluation and assessment but in a limited way.

  5. Development and evaluation of an instrument for assessing brief behavioral change interventions. (United States)

    Strayer, Scott M; Martindale, James R; Pelletier, Sandra L; Rais, Salehin; Powell, Jon; Schorling, John B


    To develop an observational coding instrument for evaluating the fidelity and quality of brief behavioral change interventions based on the behavioral theories of the 5 A's, Stages of Change and Motivational Interviewing. Content and face validity were assessed prior to an intervention where psychometric properties were evaluated with a prospective cohort of 116 medical students. Properties assessed included the inter-rater reliability of the instrument, internal consistency of the full scale and sub-scales and descriptive statistics of the instrument. Construct validity was assessed based on student's scores. Inter-rater reliability for the instrument was 0.82 (intraclass correlation). Internal consistency for the full scale was 0.70 (KR20). Internal consistencies for the sub-scales were as follows: MI intervention component (KR20=.7); stage-appropriate MI-based intervention (KR20=.55); MI spirit (KR20=.5); appropriate assessment (KR20=.45) and appropriate assisting (KR20=.56). The instrument demonstrated good inter-rater reliability and moderate overall internal consistency when used to assess performing brief behavioral change interventions by medical students. This practical instrument can be used with minimal training and demonstrates promising psychometric properties when evaluated with medical students counseling standardized patients. Further testing is required to evaluate its usefulness in clinical settings. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

  6. Development and Evaluation of a Novel Survey Tool Assessing Inpatient Consult Service Performance. (United States)

    Miloslavsky, Eli M; Chang, Yuchiao


    Subspecialty consultation in inpatient medicine is increasing, and enhancing performance of consultation services may have a broad-reaching impact. Multisource feedback is an important tool in assessing competence and improving performance. A mechanism for primary team resident feedback on performance of consult services has not been described. We developed and evaluated an instrument designed to assess internal medicine (IM) subspecialty inpatient consult service performance. We hypothesized that the instrument would be feasible to administer and provide important information to fellowship directors. The instrument was administered in 2015 and 2016 at a single academic center. All IM residents were invited to evaluate 10 IM subspecialty consult services on 4 items and an overall satisfaction rating. The instrument allowed for free-text feedback to fellows. Program directors completed another survey assessing the impact of the consult service evaluation. A total of 113 residents responded (47 in 2015 and 66 in 2016, for a combined response rate of 35%). Each of the 4 items measured (communication, professionalism, teaching, and pushback) correlated significantly with the overall satisfaction rating in univariate and multivariate analyses. There were no differences in ratings across postgraduate year or year of administration. There was considerable variation in ratings among the services evaluated. The 7 program directors who provided feedback found the survey useful and made programmatic changes following evaluation implementation. A primary team resident evaluation of inpatient medicine subspecialty consult services is feasible, provides valuable information, and is associated with changes in consult service structure and curricula.

  7. Evaluation of FCS self and peer-assessment approach based on Cooperative and Engineering Design learning. (United States)

    Cvetkovic, Dean


    The Cooperative Learning in Engineering Design curriculum can be enhanced with structured and timely self and peer assessment teaching methodologies which can easily be applied to any Biomedical Engineering curriculum. A study was designed and implemented to evaluate the effectiveness of this structured and timely self and peer assessment on student team-based projects. In comparing the 'peer-blind' and 'face-to-face' Fair Contribution Scoring (FCS) methods, both had advantages and disadvantages. The 'peer-blind' self and peer assessment method would cause high discrepancy between self and team ratings. But the 'face-to-face' method on the other hand did not have the discrepancy issue and had actually proved to be a more accurate and effective, indicating team cohesiveness and good cooperative learning.

  19. Self-Assessment and Appearance Evaluation in Student Group as Predictors in Relationships of Interpersonal Significance

    Directory of Open Access Journals (Sweden)

    Labunskaya V.A.


    Full Text Available The paper attempts to integrate the concept of relationships of interpersonal significance, approaches to the correlation between physical appearance and life satisfaction, as well as several concepts of interpersonal cognition, self-assessment and evaluations of other people’s physical appearance. It introduces the concept of “insignificant/significant assessor of appearance” and argues that among the factors that turn a group member into the “insignificant/significant assessor of appearance” are evaluations, self-evaluations and group evaluations of physical appearance. The research described in the paper involved 89 students aged 19—21 (M=20 years, 66 females and 23 males, members of five groups that have been studying together for three years. The methods employed in the study included: “The Evaluation/Content Interpretation of Appearance and its Correspondence with Gender/Age Constructs”, a technique developed by V.A. Labunskaya; a modification of a sociometric test that helped reveal “insignificant/significant assessors of appearance”. Also, nonparametric mathematical methods were used to carry out comparative analysis. The outcomes show that there are considerable differences between the self-assessments, evaluations of physical appearance of those group members who are “significant assessors of appearance”, and group evaluations of their appearance.

  1. Development and clinimetric evaluation of the mouth impairment and disability assessment (MIDA). (United States)

    Couture, Marie-Andrée; Calva, Valérie; de Oliveira, Ana; LaSalle, Léo; Forget, Nancy; Nedelec, Bernadette


    Burns of the face and mouth region have a profound impact on function. Currently the outcome measure that is most commonly used in the burn care literature is horizontal and vertical opening. Impairment-based outcomes such as this do not capture the functional implications of these injuries in spite of the devastating impact they can have on burn survivor's lives. To generate an assessment that evaluates the impairments, activity limitations, and participation restrictions associated with mouth injuries and prospectively collect data to examine the clinimetric properties. A multistep assessment development process was undertaken including a comprehensive literature search and review, burn care expert and burn survivor interviews, generation of a preliminary version and field-testing, modifications based on field testing and updated literature review, and further field testing with data collection of 23 burn survivors. Clinimetric properties were examined by evaluating: whether there was a ceiling or floor effect, the internal consistency, construct validity, and responsiveness. The mouth impairment and disability assessment (MIDA) has a 28 item self-report portion, divided into four subscales, completed by the patient and an impairment-based section completed by the burn therapist. Two items demonstrated a ceiling effect, one was removed the other retained. There was strong and statistically significant (pevaluation approximately seven and a half months after the baseline evaluation demonstrated a statistically significant change with time and treatment. The MIDA now offers clinicians the ability to assess mouth impairment and disability of burn survivors who have sustained burn injuries to their face and mouth region.

  11. A Methodology to Assess and Evaluate Rainwater Harvesting Techniques in (Semi-)Arid Regions (United States)

    Ali, Ammar; Riksen, Michel; Ouessar, Mohamed; Ritsema, Coen


    Arid and semi-arid regions around the world are generally facing water scarcity problems due to lack of precipitation and unpredictable rainfall patterns. For thousands of years rainwater harvesting (RWH) techniques have been applied to cope with water scarcity. Many researchers have presented and applied different methodologies for determining suitable sites and techniques for RWH. However, there is still little attention given to evaluation of the performance of RWH structures. The aim of this research was to design a scientifically-based and generally applicable methodology to evaluate and assess the performance of existing RWH techniques in (semi-) arid regions. The methodology takes engineering, biophysical, and socio-economic criteria into account to assess the performance of RWH using the Analytical Hierarchy Process (AHP) supported by Geographic Information System (GIS). The Oum Zessar watershed in south-eastern Tunisia is used as a case study site to test this evaluation tool. The performance of 58 RWH locations (14 jessour and 44 tabias) in three main sub-catchments of Oum Zessar watershed were assessed and evaluated. Based on the criteria selected, 60performance, 36received good performance scores. The results very accurately represent the real performance of each site. This integrated methodology, which is highly flexible, saves time and costs, and is easy to adapt in different regions, provides a scientifically based analytical tool to support designers and decision makers aiming to improve the performance of existing and new RWH sites.

However, the current swine building environmental control is only based on temperature; and evaluation and control methods based on multiple environmental factors are needed. In this paper, fuzzy comprehensive evaluation (FCE) theory was adopted for multi-factor assessment of environmental quality in two commercial swine buildings using real measurement data. An assessment index system and membership functions were established; and predetermined weights were given using analytic hierarchy process (AHP) combined with knowledge of experts. The results show that multi-factors such as temperature, humidity, and concentrations of ammonia (NH 3 ), carbon dioxide (CO 2 ), and hydrogen sulfide (H 2 S) can be successfully integrated in FCE for swine building environment assessment. The FCE method has a high correlation coefficient of 0.737 compared with the method of single-factor evaluation (SFE). The FCE method can significantly increase the sensitivity and perform an effective and integrative assessment. It can be used as part of environmental controlling and warning systems for swine building environment management to improve swine production and welfare. Copyright © 2017 Elsevier B.V.

  13. Improving internal medicine residents' falls assessment and evaluation: an interdisciplinary, multistrategy program. (United States)

    Caton, Cathryn; Wiley, M Kathleen; Zhao, Yumin; Moran, William P; Zapka, Jane


    Falls are a major problem in older adults, and physicians receive inadequate training in falls evaluation. A multicomponent program (lecture, academic detailing, and case studies) was implemented to enhance medical residents' knowledge, skills, decisions, and interventions made about falls as part of a larger project to improve assessment and care of older adults. Electronic medical record (EMR) template modifications provided cues and reminders, decision support, and documentation into the visit note. Nursing staff and the EMR prompted residents to evaluate patients with a history of falls. Knowledge and confidence were assessed using a pre- and postintervention questionnaire, and an attending physician assessed skills by direct observation of the Timed Up and Go Test (TUG). Effect on clinical actions was assessed using the EMR database. Participation in training of faculty and staff was high. Over the 3-month intervention period, an attending physician reviewed the detailing sheet outlining important points of the training with 86% of residents, and 64% demonstrated a TUG to an attending physician. Of 895 older adults seen, 15% (134) had a positive screen for falls, of whom 92% (123) had an EMR falls template completed, and 42% (56) had a TUG performed. Of the patients evaluated with the TUG, 53% (29) failed. A review of charts for patients who failed the screen or TUG revealed that the majority had special circumstances limiting their participation, even after a physical therapy evaluation. Education and system changes facilitated improvements in resident knowledge, skill, self-efficacy, and clinical action in screening, evaluating, and managing falls in older adults. © 2011, Copyright the Authors.

  15. Pharmacy students' perceptions of and attitudes towards peer assessment within a drug literature evaluation course. (United States)

    Wu, Kimberly; Davison, Lindsay; Heck Sheehan, Amy


    To assess pharmacy students' perceptions of and attitudes towards the use of peer assessment within a drug literature evaluation course. A 15-item, electronic survey instrument was sent to 158 second-year pharmacy students enrolled in a 2-credit required literature evaluation course at the Purdue University College of Pharmacy. One hundred fifty-two (96.2%) responses were received. Approximately 95% of students agreed that they had the necessary skills to assess their peers and 91.8% agreed that their peers possessed these skills as well. More students agreed they were comfortable receiving feedback from peers (95.7%) than agreed they were comfortable providing feedback to peers (80%). The majority of students (91.9%) agreed that peer assessment was a skill they will use in their career as a pharmacist. Students were more comfortable receiving feedback from peers than providing peer assessment. This skill is used by pharmacists throughout their career; therefore, students should become familiar and comfortable with the peer assessment process.

  16. The Design and Evaluation of the Comprehensive Hospitalist Assessment and Mentorship with Portfolios (CHAMP) Ultrasound Program. (United States)

    Mathews, Benji K; Reierson, Kreegan; Vuong, Khuong; Mehta, Ankit; Miller, Paula; Koenig, Seth; Narasimhan, Mangala


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

  17. Avoiding honest feedback: discordance between formal evaluations and candid assessments of Kuwaiti PBL students. (United States)

    Qadan, Laila; Al-Ozairi, Ebaa; Ayed, Adel; Huang, Grace


    Problem-based learning (PBL) allows faculty to observe students interact and solve problems. Thus, it represents a prime opportunity to provide authentic feedback on learners' knowledge, skills, and attitudes. However, we are concerned that PBL faculty do not accurately convey feedback to students. To assess the difference between formal evaluations and candid assessments of student performance, we conducted a study of 178 preclinical medical students at Kuwait University. We quantitatively compared PBL evaluations of students with candid assessments of students' competence as obtained from structured interviews with 19 PBL facilitators. We also compared facilitators' comments on the module evaluations with candid comments solicited during the interviews. We did not find a strong quantitative or qualitative correlation between faculty feedback and their candid impressions of student performance. Thematic analysis of the comments disclosed multiple factors that influenced the accuracy and specificity of faculty feedback. Systematic discrepancies between feedback given to students and actual assessments of their performance can result in false reassurance of competence, which undermines our curricular efforts and prevents the trainee from achieving his or her full potential.

  18. An assessment of implementation and evaluation phases of strategic plans in Iranian hospitals. (United States)

    Sadeghifar, Jamil; Tofighi, Shahram; Roshani, Mohamad; Toulideh, Zahra; Mohsenpour, Seyedramezan; Jafari, Mehdi


    To assess the implementation and evaluation phases of strategic plans in selected hospitals. We conducted a cross-sectional study of implementation and evaluation of strategic plan in 24 hospitals in 2015, using a questionnaire which consisted of two separate sections for strategic implementation and strategic evaluation. Data were analyzed with SPSS version 18. Nearly one-third of hospitals claimed that they allocate their budget based on priorities and strategic goals. However, it turned out that although goals had been set, no formal announcements had been made. Most of the hospitals stated that they used measures when evaluating the plan. For hospital staff, clarifying the hospital's priorities was the most important advantage of a strategic plan. There is no clear definition for strategic management in Iranian hospitals, which results in chaotic implementation and control of strategic planning.

  19. Are we bridging the gap? Evaluating climate assessment and translational science efforts in the US Southwest (United States)

    Ferguson, D. B.; Browning-Aiken, A.; Garfin, G.; McDonald, D.; Rice, J.; Stuart, M.


    Instituted in 1998 as part of NOAA's Regional Integrated Sciences and Assessments program, the Climate Assessment for the Southwest (CLIMAS) program has conducted 10 years of use-inspired science aimed at improving the ability of decision makers in the southwestern United States to respond to climate variability and change. Beginning in the Fall of 2007, we began a pilot evaluation project to understand better how the work done by CLIMAS is impacting the communities with whom we work. The evaluation approach combined qualitative and quantitative methods to understand stakeholder, partner, and collaborator perspectives on CLIMAS work. The primary goals of the project were to determine: (a) penetration of CLIMAS information to stakeholders, (b) the perceived salience, credibility, and legitimacy of CLIMAS research and outreach, and (c) changes in stakeholder attitudes, knowledge, and behavior as a result of partnerships and collaborative processes. This presentation will briefly focus on two aspects of this evaluation effort: 1) key results from the evaluation, with a particular emphasis on whom the program is reaching and examples of CLIMAS work successfully informing decision making processes; 2) insights and lessons learned from the evaluation process itself.

  1. Identifying and assessing strategies for evaluating the impact of mobile eye health units on health outcomes. (United States)

    Fu, Shiwan; Turner, Angus; Tan, Irene; Muir, Josephine


    To identify and assess strategies for evaluating the impact of mobile eye health units on health outcomes. Systematic literature review. Worldwide. Peer-reviewed journal articles that included the use of a mobile eye health unit. Journal articles were included if outcome measures reflected an assessment of the impact of a mobile eye health unit on health outcomes. Six studies were identified with mobile services offering diabetic retinopathy screening (three studies), optometric services (two studies) and orthoptic services (one study). This review identified and assessed strategies in existing literature used to evaluate the impact of mobile eye health units on health outcomes. Studies included in this review used patient outcomes (i.e. disease detection, vision impairment, treatment compliance) and/or service delivery outcomes (i.e. cost per attendance, hospital transport use, inappropriate referrals, time from diabetic retinopathy photography to treatment) to evaluate the impact of mobile eye health units. Limitations include difficulty proving causation of specific outcome measures and the overall shortage of impact evaluation studies. Variation in geographical location, service population and nature of eye care providers limits broad application. © 2017 National Rural Health Alliance Inc.

  2. A National Research Council Evaluation of the Department of Energy's Marine and Hydrokinetic Resource Assessments (United States)

    Glickson, D.; Holmes, K. J.; Cooke, D.


    Marine and hydrokinetic (MHK) resources are increasingly becoming part of energy regulatory, planning, and marketing activities in the U.S. and elsewhere. In particular, state-based renewable portfolio standards and federal production and investment tax credits have led to an increased interest in the possible deployment of MHK technologies. The Energy Policy Act of 2005 (Public Law 109-58) directed the Department of Energy (DOE) to estimate the size of the MHK resource base. In order to help DOE prioritize its overall portfolio of future research, increase the understanding of the potential for MHK resource development, and direct MHK device and/or project developers to locations of greatest promise, the DOE Wind and Water Power Program requested that the National Research Council (NRC) provide an evaluation of the detailed assessments being conducted by five individual resource assessment groups. These resource assessment groups were contracted to estimate the amount of extractable energy from wave, tidal, ocean current, ocean thermal energy conversion, and riverine resources. Performing these assessments requires that each resource assessment group estimate the average power density of the resource base, as well as the basic technology characteristics and spatial and temporal constituents that convert power into electricity for that resource. The NRC committee evaluated the methodologies, technologies, and assumptions associated with each of these resource assessments. The committee developed a conceptual framework for delineating the processes used to develop the assessment results requested by the DOE, with definitions of the theoretical, technical, and practical resource to clarify elements of the overall resource assessment process. This allowed the NRC committee to make a comparison of different methods, terminology, and processes among the five resource assessment groups. The committee concluded that the overall approach taken by the wave resource and

  3. Comparative study between subjective assessment and quantitative evaluation of CT findings with cerebral palsy

    Energy Technology Data Exchange (ETDEWEB)

    Sugie, Y.; Sugie, H.; Kitai, A.; Maruyama, H.; Fukuyama, Y. (Tokyo Women' s Medical Coll. (Japan))


    Computed tomography (CT) was performed on 200 children with cerebral palsy with Hitachi CT-H250. The CT scans of 136 cases revealed cerebral atrophy with ventricular and/or subarachnoid space enlargement. The lateral ventricles, the third ventricle and the two parts of subarachnoid space on the CT picture were subjectively evaluated and divided into five grades ranging from no enlargement to marked enlargement. In addition, the size of the ventricles and the subarachnoid spaces were quantitatively determined; the transverse diameter of brain (b), the largest width of the anterior horns of the lateral ventricles (c), the bicaudate nuclear distance (d), the greatest width of the third ventricle, the longitudinal cerebral fissure and sylvian fissures as described by Miyao et al. (1978). Comparison of these quantitative techniques confirmed the initial subjective evaluation. However, in some cases, amendment of the subjective evaluation was needed. As mentioned before (Miyao et al.), the cerebral longitudinal fissure was relatively wide in normal infants. Accordingly, it was often difficult to find out abnormal widening only by subjective evaluation. The purpose of this paper was to establish the criteria of quantitative measuring and assessing of the lateral and third ventricles, the cerebral longitudinal fissures, and the sylvian fissures enlargement. Interpretation of some problem cases associated with measuring was also discussed. The quantitative CT evaluation may be a good reference in assessing cerebral atrophy in cerebral palsy and other neurological diseases.

  4. Residential traffic noise exposure assessment: application and evaluation of European Environmental Noise Directive maps. (United States)

    Eriksson, Charlotta; Nilsson, Mats E; Stenkvist, Dag; Bellander, Tom; Pershagen, Göran


    Digital noise maps produced according to the European Environmental Noise Directive (END) could provide valuable exposure information in noise and health research. However, their usefulness in epidemiological studies has not been evaluated. The objective of this study was to apply and evaluate Swedish END maps for assessments of residential traffic noise exposure. END maps from three Swedish cities were used to assess residential traffic noise exposure for a population sample of 2496 men and women included in a national Environmental Health Survey. For each subject, we assessed noise levels manually and automatically at three geographical points, using survey data to locate dwellings within buildings. Cohen's kappa coefficient (κ) was used to assess agreement between the noise estimates. To evaluate the maps, we compared the observed and predicted proportions of annoyed residents as a function of noise exposure using survey data and already established exposure-response relationships. The root mean square deviation (r.m.s.) was used to assess the precision of observed estimates. The agreement between the noise estimates ranged from κ=0.4 to 0.8. Generally, there was a high correspondence between observed and predicted exposure-response relationships for noise annoyance, regardless of method and if data on dwelling location within building were used. The best precision was, however, found when we manually corrected the noise level according to the location of the dwelling within buildings (r.m.s.=0.029). Noise maps based on the END appear useful for assessing residential traffic noise exposure, particularly if combined with survey data on dwelling location.

  6. Image Navigation and Registration Performance Assessment Evaluation Tools for GOES-R ABI and GLM (United States)

    Houchin, Scott; Porter, Brian; Graybill, Justin; Slingerland, Philip


    The GOES-R Flight Project has developed an Image Navigation and Registration (INR) Performance Assessment Tool Set (IPATS) for measuring Advanced Baseline Imager (ABI) and Geostationary Lightning Mapper (GLM) INR performance metrics in the post-launch period for performance evaluation and long term monitoring. IPATS utilizes a modular algorithmic design to allow user selection of data processing sequences optimized for generation of each INR metric. This novel modular approach minimizes duplication of common processing elements, thereby maximizing code efficiency and speed. Fast processing is essential given the large number of sub-image registrations required to generate INR metrics for the many images produced over a 24 hour evaluation period. This paper describes the software design and implementation of IPATS and provides preliminary test results.

  7. Assessment practices of Irish speech and language therapists in the evaluation of voice disorders. (United States)

    Kenny, Ciarán


    It is commonly accepted that the evaluation of voice disorders ought to include extensive perceptual, psychometric, and instrumental measurements. This serves to encapsulate the wide-reaching effects of such a disorder, from the physical impairment in voice production to the psycho-social impact of having a dysphonic voice. In spite of this, no international gold standard exists by which voice disorders should be evaluated, and so speech and language therapists (SLTs) are often tasked with developing an assessment battery for use in their own clinics. The purpose of this study is to determine whether the evaluation of voice disorders by Irish SLTs on a national scale is suitably comprehensive, with particular reference to the guidelines published by the European Laryngological Society. A total of 49 SLTs working in a variety of settings responded anonymously to an electronic survey regarding their assessment practices. Results indicate that therapists are comprehensive in non-instrumental evaluation of voice, but lack both access to and training in instrumental assessment techniques.

    Holcomb, K E; Stull, C L


    The effects of solar or UV radiation on livestock are often evaluated in research focused on heat stress, dermatological conditions, and other topics, with radiation measurements recorded by instrumentation at a field or local weather station for a general geographical location. Individual sensors would be valuable for quantifying an individual animal's exposure, especially as they move about in a heterogeneous environment. Individual commercially available UV dosimeters were evaluated for specificity and sensitivity and found to be potentially valuable research tools for assessing and comparing the UV radiation exposure of individual animals.

  14. Industrial Assessment Center Program Impact Evaluation

    Energy Technology Data Exchange (ETDEWEB)

    Martin, M.A.


    This report presents the results of an evaluation of the U.S. Department of Energy's Industrial Assessment Center (IAC) Program. The purpose of this program is to conduct energy, waste, and productivity assessments for small to medium-sized industrial firms. Assessments are conducted by 30 university-based industrial assessment centers. The purpose of this project was to evaluate energy and cost savings attributable to the assessments, the trained alumni, and the Websites sponsored by this program. How IAC assessments, alumni, and Web-based information may influence industrial energy efficiency decision making was also studied. It is concluded that appreciable energy and cost savings may be attributed to the IAC Program and that the IAC Program has resulted in more active and improved energy-efficiency decision making by industrial firms.

  15. A quantitative screening-level approach to incorporate chemical exposure and risk into alternative assessment evaluations. (United States)

    Arnold, Scott M; Greggs, Bill; Goyak, Katy O; Landenberger, Bryce D; Mason, Ann M; Howard, Brett; Zaleski, Rosemary T


    As the general public and retailers ask for disclosure of chemical ingredients in the marketplace, a number of hazard screening tools were developed to evaluate the so-called "greenness" of individual chemical ingredients and/or formulations. The majority of these tools focus only on hazard, often using chemical lists, ignoring the other part of the risk equation: exposure. Using a hazard-only focus can result in regrettable substitutions, changing 1 chemical ingredient for another that turns out to be more hazardous or shifts the toxicity burden to others. To minimize the incidents of regrettable substitutions, BizNGO describes "Common Principles" to frame a process for informed substitution. Two of these 6 principles are: "reduce hazard" and "minimize exposure." A number of frameworks have emerged to evaluate and assess alternatives. One framework developed by leading experts under the auspices of the US National Academy of Sciences recommended that hazard and exposure be specifically addressed in the same step when assessing candidate alternatives. For the alternative assessment community, this article serves as an informational resource for considering exposure in an alternatives assessment using elements of problem formulation; product identity, use, and composition; hazard analysis; exposure analysis; and risk characterization. These conceptual elements build on practices from government, academia, and industry and are exemplified through 2 hypothetical case studies demonstrating the questions asked and decisions faced in new product development. These 2 case studies-inhalation exposure to a generic paint product and environmental exposure to a shampoo rinsed down the drain-demonstrate the criteria, considerations, and methods required to combine exposure models addressing human health and environmental impacts to provide a screening level hazard and exposure (risk) analysis. This article informs practices for these elements within a comparative risk context

  16. The Operating Characteristics of the Nonparametric Levene Test for Equal Variances with Assessment and Evaluation Data

    Directory of Open Access Journals (Sweden)

    David W. Nordstokke


    Full Text Available Many assessment and evaluation studies use statistical hypothesis tests, such as the independent samples t test or analysis of variance, to test the equality of two or more means for gender, age groups, cultures or language group comparisons. In addition, some, but far fewer, studies compare variability across these same groups or research conditions. Tests of the equality of variances can therefore be used on their own for this purpose but they are most often used alongside other methods to support assumptions made about variances. This is often done so that variances can be pooled across groups to yield an estimate of variance that is used in the standard error of the statistic in question. The purposes of this paper are twofold. The first purpose is to describe a new nonparametric Levene test for equal variances that can be used with widely available statistical software such as SPSS or SAS, and the second purpose is to investigate this test's operating characteristics, Type I error and statistical power, with real assessment and evaluation data. To date, the operating characteristics of the nonparametric Levene test have been studied with mathematical distributions in computer experiments and, although that information is valuable, this study will be an important next step in documenting both the level of non-normality (skewness and kurtosis of real assessment and evaluation data, and how this new statistical test operates in these conditions.

  18. Evaluating an Online Family Assessment Activity: A Focus on Diversity and Health Promotion. (United States)

    Smith, Paul S; Jones, Melissa


    A lack of exposure to diverse families and family interactions created a need to identify effective teaching strategies that emphasized diversity and health promotion in a Registered Nurse to Bachelor of Science in Nursing online transition course. A family assessment activity was designed to emphasize diversity and health promotion utilizing the Family Health Systems approach to family assessment and Healthy People 2020 as a framework for family health promotion. The activity was evaluated through faculty observation and student feedback, which is discussed in the article. Evaluation data indicated that students believed the activity provided a safe environment to practice assessment skills for working with diverse families, pushed them out of their comfort zones, enhanced their awareness of the need for health promotion, extended their definition of diversity, increased their cultural knowledge, expanded their personal perspectives on families, and provided them with a broader scope of nursing practice in the community. Using constructivist strategies that emphasize active learning and the use of cinema to teach family assessment results in increased awareness of diversity and increased knowledge of opportunities for health promotion in families.

  19. Assessment of recovery in older patients hospitalized with different diagnoses and functional levels, evaluated with and without geriatric assessment. (United States)

    Abrahamsen, Jenny Foss; Haugland, Cathrine; Ranhoff, Anette Hylen


    The objective of the present study was to investigate 1) the role of different admission diagnoses and 2) the degree of functional loss, on the rate of recovery of older patients after acute hospitalization. Furthermore, to compare the predictive value of simple assessments that can be carried out in a hospital lacking geriatric service, with assessments including geriatric screening tests. Prospective, observational cohort study, including 961community dwelling patients aged ≥ 70 years, transferred from medical, cardiac, pulmonary and orthopedic acute hospital departments to intermediate care in nursing home. Functional assessment with Barthel index (BI) was performed at admission to the nursing home and further geriatric assessment tests was performed during the first week. Logistic regression models with and without geriatric assessment were compared concerning the patients having 1) slow recovery (nursing home stay up to 2 months before return home) or, 2) poor recovery (dead or still in nursing home at 2 months). Slow recovery was independently associated with a diagnosis of non-vertebral fracture, BI subgroups 50-79 and geriatric assessment, also with cognitive impairment. Poor recovery was more complex, and independently associated both with BI geriatric assessment model, cognitive impairment. Geriatric assessment is optimal for determining the recovery potential of older patients after acute hospitalization. As some hospitals lack geriatric services and ability to perform geriatric screening tests, a simpler assessment based on admission diagnoses and ADL function (BI), gives good information regarding the possible rehabilitation time and possibility to return home.

  20. A prospective study assessing agreement and reliability of a geriatric evaluation. (United States)

    Locatelli, Isabella; Monod, Stéfanie; Cornuz, Jacques; Büla, Christophe J; Senn, Nicolas


    The present study takes place within a geriatric program, aiming at improving the diagnosis and management of geriatric syndromes in primary care. Within this program it was of prime importance to be able to rely on a robust and reproducible geriatric consultation to use as a gold standard for evaluating a primary care brief assessment tool. The specific objective of the present study was thus assessing the agreement and reliability of a comprehensive geriatric consultation. The study was conducted at the outpatient clinic of the Service of Geriatric Medicine, University of Lausanne, Switzerland. All community-dwelling older persons aged 70 years and above were eligible. Patients were excluded if they hadn't a primary care physician, they were unable to speak French, or they were already assessed by a geriatrician within the last 12 months. A set of 9 geriatricians evaluated 20 patients. Each patient was assessed twice within a 2-month delay. Geriatric consultations were based on a structured evaluation process, leading to rating the following geriatric conditions: functional, cognitive, visual, and hearing impairment, mood disorders, risk of fall, osteoporosis, malnutrition, and urinary incontinence. Reliability and agreement estimates on each of these items were obtained using a three-way Intraclass Correlation and a three-way Observed Disagreement index. The latter allowed a decomposition of overall disagreement into disagreements due to each source of error variability (visit, rater and random). Agreement ranged between 0.62 and 0.85. For most domains, geriatrician-related error variability explained an important proportion of disagreement. Reliability ranged between 0 and 0.8. It was poor/moderate for visual impairment, malnutrition and risk of fall, and good/excellent for functional/cognitive/hearing impairment, osteoporosis, incontinence and mood disorders. Six out of nine items of the geriatric consultation described in this study (functional

  1. Significant discrepancies exist between clinician assessment and patient self-assessment of functional capacity by validated scoring tools during preoperative evaluation. (United States)

    Stokes, John Whittemore; Wanderer, Jonathan Porter; McEvoy, Matthew David


    Preoperative assessment of functional capacity is necessary to direct decisions regarding cardiac evaluation and may help identify patients at high risk for perioperative complications. Patient self-triage regarding functional capacity could be useful for discerning which patients benefit from a clinician evaluation at a Preoperative Evaluation Center prior to the day of surgery. We evaluated the feasibility of preoperative, patient self-triage regarding functional capacity. Patients were recruited immediately prior to their preoperative evaluation. Study participants completed electronic versions of the Duke Activity Status Index (DASI) and the Patient-Reported Outcomes Measurement System (PROMIS)-Short Form 12a-Physical Function. DASI and PROMIS questionnaire responses were scored and evaluated for correlation with clinician assessments of functional capacity. Correlation was analyzed around the dichotomous outcome of evaluated the usability of the questionnaires. After IRB approval, 204 patients were enrolled and completed both DASI and PROMIS questionnaires. Clinicians assessed functional capacity at assessments assessments (Fisher's exact, two-tailed P value assessments and patient self-assessments of functional capacity. Further study is needed to determine if either patient self-triage by means of activity questionnaires or clinician evaluation is valid and reliable in the preoperative setting.

  3. Safety assessment and global regulatory requirements for genetic toxicity evaluations of medical devices. (United States)

    Przygoda, Robert T


    Medical devices have the potential to leach substances which, depending on the contact category of the device, can directly contact the human body. Hence, appropriate evaluation for genetic toxicity as part of the biocompatibility risk assessment is critical. The biocompatibility risk assessment of medical devices is guided by the ISO 10993 series of standards. The recently revised ISO 10993-3 (2014) provides guidance on evaluating the genotoxicity, carcinogenicity and reproductive toxicity potential of medical devices. The revised standard includes the use of risk assessments and chemical characterization in addition to traditional genetic toxicity tests. The ISO 10993-3 standard provides guidance on the selection and preparation of test samples, and the selection of tests to evaluate genetic toxicity. Although conformance to ISO 10993-3 is required by various national regulatory agencies for specific medical device categories, there are still differences in the interpretation of the requirements within the standard which may require additional testing.

  4. Probability and Confidence Trade-space (PACT) Evaluation: Accounting for Uncertainty in Sparing Assessments (United States)

    Anderson, Leif; Box, Neil; Carter, Katrina; DiFilippo, Denise; Harrington, Sean; Jackson, David; Lutomski, Michael


    There are two general shortcomings to the current annual sparing assessment: 1. The vehicle functions are currently assessed according to confidence targets, which can be misleading- overly conservative or optimistic. 2. The current confidence levels are arbitrarily determined and do not account for epistemic uncertainty (lack of knowledge) in the ORU failure rate. There are two major categories of uncertainty that impact Sparing Assessment: (a) Aleatory Uncertainty: Natural variability in distribution of actual failures around an Mean Time Between Failure (MTBF) (b) Epistemic Uncertainty : Lack of knowledge about the true value of an Orbital Replacement Unit's (ORU) MTBF We propose an approach to revise confidence targets and account for both categories of uncertainty, an approach we call Probability and Confidence Trade-space (PACT) evaluation.

  5. Practitioner evaluation of a novel online integrated oral health and risk assessment tool: a practice pilot. (United States)

    Busby, M; Chapple, E; Matthews, R; Chapple, I L C


    To report the development and evaluation of an evidence-based, online, patient assessment tool, capable of measuring oral health status, future disease risk and capitation fee guidance. An online integrated oral health and risk assessment tool called DEPPA was developed, incorporating 1) PreViser(™) risk scores for periodontal disease, caries, non-carious tooth surface loss and oral cancer, 2) revised versions of Denplan Excel's Oral Health Score and 3) capitation fee guidance score. DEPPA was piloted by 25 dentists who provided quantitative and qualitative feedback. Six hundred and forty assessments were performed. There was strong agreement on the need for such a tool, that it constituted a comprehensive assessment and supported good patient communication. The validity of the system was perceived as sound and the revised capitation fee guidance broadly welcomed. While some deemed the caries risk scoring algorithm to be too sensitive, the 30% high/very high risk rating is consistent with current rates of active caries in UK adults. A viable online oral health and risk-assessment tool has been developed (DEPPA) that will allow dental teams to measure oral health status, future disease risk and receive ongoing guidance on capitation fee setting. The indications are that DEPPA could be a valuable audit, care planning and patient communication tool.

  6. Assessing supervisory and motivational factors in the context of a program evaluation in rural Haiti. (United States)

    Menon, Purnima; Mbuya, Mduduzi; Habicht, Jean-Pierre; Pelto, Gretel; Loechl, Cornelia U; Ruel, Marie T


    Staff supervisory and motivational factors were assessed in the context of an ongoing program evaluation in Haiti comparing 2 models of targeting an integrated health and nutrition program. The study objectives were to 1) understand and improve supervisory and motivational factors influencing program implementation and 2) compare these factors between the 2 program models being evaluated. Qualitative methods (focus group discussions and semistructured interviews) were used to understand factors related to supervision and motivation. Quantitative measures of supervisory and motivational factors were designed, and factor analysis was used, to develop summary scales of motivational factors and supervision. T-tests were used to compare mean scores on the scales between the 2 program models. Results from the qualitative research were discussed with program management and staff to help develop solutions to implementation bottlenecks. Staff at all levels of the program seemed motivated and generally well supervised. Constraints to motivation included perceived inadequacy of wages (before changes were made to salaries), heavy workloads, and logistical constraints. We found no salient differences between the 2 program models that could contribute to differential implementation or differences in impact. This lack of salient differences between the program models suggested that supervisory and motivational factors were unlikely to contribute to differences in impact. Assessing supervisory and motivational factors was feasible and desirable in the context of this evaluation and deepened understanding of the program context and constraints to implementation.

  7. Subjective evaluation of running footwear depends on country and assessment method: a bi-national study. (United States)

    Kong, Pui W; Lim, Chen Y; Ding, Rui; Sterzing, Thorsten


    This study examined (1) the perception of running shoes between China (Beijing) and Singapore and (2) whether running shoe preference depended on assessment methods. One hundred (n = 50 each country) Chinese males subjectively evaluated four shoe models during running by using two assessment procedures. Procedure 1 used a visual analogue scale (VAS) to assess five perception variables. Procedure 2 was a 'head-to-head' comparison of two shoes simultaneously (e.g. left foot: A and right foot: B) to decide which model was preferred. VAS scores were consistently higher in Beijing participants (p shoe discrimination. Moderate agreement was seen between the VAS and 'head-to-head' procedures, with only 14 out of 100 participants matched all 6 pairwise comparisons (median = 4 matches). Footwear companies and researchers should be aware that subjective shoe preference may vary with assessment methods. Practitioner Summary: Footwear preference depends on country and assessment methods. Running shoe perception differed between Beijing and Singapore Chinese, suggesting that footwear recommendation should be country-specific. Individuals' shoe preference measured by visual analogue scale when wearing complete pairs may not reflect that when directly comparing different models in left and right feet.

  11. Fostering and evaluating reflective capacity in medical education: developing the REFLECT rubric for assessing reflective writing. (United States)

    Wald, Hedy S; Borkan, Jeffrey M; Taylor, Julie Scott; Anthony, David; Reis, Shmuel P


    Reflective writing (RW) curriculum initiatives to promote reflective capacity are proliferating within medical education. The authors developed a new evaluative tool that can be effectively applied to assess students' reflective levels and assist with the process of providing individualized written feedback to guide reflective capacity promotion. Following a comprehensive search and analysis of the literature, the authors developed an analytic rubric through repeated iterative cycles of development, including empiric testing and determination of interrater reliability, reevaluation and refinement, and redesign. Rubric iterations were applied in successive development phases to Warren Alpert Medical School of Brown University students' 2009 and 2010 RW narratives with determination of intraclass correlations (ICCs). The final rubric, the Reflection Evaluation for Learners' Enhanced Competencies Tool (REFLECT), consisted of four reflective capacity levels ranging from habitual action to critical reflection, with focused criteria for each level. The rubric also evaluated RW for transformative reflection and learning and confirmatory learning. ICC ranged from 0.376 to 0.748 for datasets and rater combinations and was 0.632 for the final REFLECT iteration analysis. The REFLECT is a rigorously developed, theory-informed analytic rubric, demonstrating adequate interrater reliability, face validity, feasibility, and acceptability. The REFLECT rubric is a reflective analysis innovation supporting development of a reflective clinician via formative assessment and enhanced crafting of faculty feedback to reflective narratives.

    I. Alimohammadi


    Full Text Available Background and aims   The Rula procedure was based on the model of OWAS which, developed by the Finish Institute of Occupational Health and the Ovako Steel Company to investigate problems of lifting and of back injuries. This process required that segments of the body by judged on a simple scale, producing a sequence of numbers which were matched against a grid. The value of the numbers and their position of the number improved the situation. Rula extends this assessment process to the control upper limb disorders. This method was designed for rapid assessment of posture in Neck, Trunk, Legs and Upper Limbs that includes a scoring system. In this method we use posture diagram and scoring tables for the purpose of presenting encounter evaluation with risk factors.   Methods   Rula will execute in three steps: posture register, scoring system, identifying action levels. This research performed in an electronics and electricity device manufacturing company with the aim of studying and evaluating posture by Rula method.

    Full Text Available Thesis examination is one of the crucial phases for students in undergraduate level. During the examination, they are required to perform best to get the maximum score which commonly is equal to six credits. Looking at the big portion of credit, the examination highly determines the student‘s GPA at last. In order to get the accurate and fair score, the appropriate assessment must be implemented by the board of examiners. The form of assessment may vary from one institution to another. This paper is aimed at discussing as well as evaluating the assessment of undergraduate thesis examination at STKIP PGRI Ponorogo, East Java, Indonesia. The evaluation was based on the principles of good assessment adapted from Brown (2003 comprised of practicality, reliability, validity, and authenticity. Based on the result of evaluation, the form of assessment on undergraduate thesis examination administered at STKIP PGRI Ponorogo hasn‘t fully fulfilled the principles of good assessment. The findings also revealed that some assessment indicators need to be improved, such as the formulation of statement, the number of assessment item, and the technical procedure on how to administer the assessment.

    Wang, Cheng; Qian, Xin; Li, Hui-ming; Sun, Yi-xuan; Wang, Jin-hua


    Contents of heavy metals involving As, Cd, Cr, Cu, Ni, Pb and Zn from atmospheric deposition in 10 parks of Nanjing were analyzed. The pollution level, ecological risk and health risk were evaluated using Geoaccumulation Index, Potential Ecological Risk Index and the US EPA Health Risk Assessment Model, respectively. The results showed that the pollution levels of heavy metals in Swallow Rock Park, Swallow Rock Park and Mochou Lake Park were higher than the others. Compared to other cities such as Changchun, Wuhan and Beijing, the contents of heavy metals in atmospheric deposition of parks in Nanjing were higher. The evaluation results of Geoaccumulation Index showed that Pb was at moderate pollution level, Zn and Cu were between moderate and serious levels, while Cd was between serious and extreme levels. The ecological risk level of Cd was high. The assessment results of Health Risk Assessment Model indicated that there was no non-carcinogenic risk for all the seven heavy metals. For carcinogenic risk, the risks of Cd, Cr and Ni were all negligible (Risk < 1 x 10⁻⁶), whereas As had carcinogenic risk possibility but was considered to be acceptable (10⁻⁶ < Risk < 10⁻⁴).

  17. Design evaluation in technology assessment: Illustrated by auditory impedance and sound distribution problems (United States)

    Halldane, J. F.


    Technology is considered as a culture for changing a physical world and technology assessment questions the inherent cultural capability to modify power and material in support of living organisms. A comprehensive goal-parameter-synthesis-criterion specification is presented as a basis for a rational assessment of technology. The thesis queries the purpose of the assessed problems, the factors considered, the relationships between factors, and the values assigned those factors to accomplish the appropriate purpose. Stationary and sequential evaluation of enviro-organismic systems are delegated to the responsible personalities involved in design; from promoter/designer through contractor to occupant. Discussion includes design goals derived from organismic factors, definitions of human responses which establish viable criteria and relevant correlation models, linking stimulus parameters, and parallel problem-discipline centered design organization. A consistent concept of impedance, as a degradation in the performance of a specified parameter, is introduced to overcome the arbitrary inoperative connotations of terms like noise, discomfort, and glare. Applications of the evaluative specification are illustrated through design problems related to auditory impedance and sound distribution.

  18. Practical Applications of Generalizability Theory for Designing, Evaluating, and Improving Psychological Assessments. (United States)

    Vispoel, Walter P; Morris, Carrie A; Kilinc, Murat


    In this article, we illustrate how generalizability theory (G-theory) can extend traditional assessment methods for designing, improving, and evaluating results from both objectively and subjectively scored measures of individual differences. Our illustrations include quantification of multiple sources of measurement error, derivation of unique indexes of consistency for norm- and criterion-referenced interpretations of scores, estimation of score consistency when changing a measurement procedure, and disattenuation of correlation coefficients for measurement error. We also expand G-theory analyses beyond the item level to include parcels and split measures and highlight linkages among G-theory, classical test theory, and structural equation modeling. Computer code and sample data are provided in online supplements to help readers apply the demonstrated techniques to their own assessments.

    Pereira da Silva, A; Matos, A; Valente, A; Gil, Â; Alonso, I; Ribeiro, R; Bicho, M; Gorjão-Clara, J


    To assess body composition, nutritional status and its differences between genders in a sample of Portuguese centenarians. Observational cross-sectional study. Centenarians recruited in Portugal, able to give informed consent. A total of 252 subjects, with a median age of 100 years, mostly women (77.8%) who accepted to participate in the study, during the period of 2012 to 2014. Anthropometric data collected (weight, height, BMI, waist circumference, hip and waist/hip ratio) were evaluated according to WHO criteria. A portable tetrapolar bioimpedance analyzer was used to calculate body composition and to assess resting metabolism. Nutritional status was evaluated according to three different criteria: BMI, waist circumference and body fat percentage using anthropometric equations and bioimpedance. We observed an overall mean weight of 51.02±11.03Kg, height of 1.55±0.07m and a BMI of 21.07±3.69Kg/m2. For most of the evaluated parameters, we found substantial differences between genders. The prevalence of underweight and overweight were 25.3% and 13.3%, respectively. Only 5 subjects were obese. Overweight subjects were mostly men (W=10.6% vs. M=22.6%), whereas women were more underweight (W=28.7% vs. M=13.2%). When considering the waist circumference, 26.5% were above the cut-off value. Most of centenarians (72.9%) had a healthy level of visceral fat. This measurement was highly correlated with waist circumference (r= 0.687, pnutritional approach should be improved on the gender basis. In relation to nutritional status, centenarians were more frequently underweight than overweight. The thinness could be a natural process, contributing for the longevity being rather overweight a reducing factor in life expectancy. BMI and waist circumference showed a good correlation with body fat percentage. Despite the results of Bland- Altman analysis, Deurenberg and Gallagher equations are not suitable to evaluate obesity prevalence in centenarians. Harris Benedict equation

  20. Evaluation of the degree of pancreatic fatty infiltration by area-based assessment of CT images: comparison with histopathology-based and CT attenuation index-based assessments. (United States)

    Hori, Mika; Onaya, Hiroaki; Hiraoka, Nobuyoshi; Yamaji, Taiki; Kobayashi, Hideaki; Takahashi, Mami; Mutoh, Michihiro; Shimada, Kazuaki; Nakagama, Hitoshi


    The purpose of this study was to evaluate the degree of fatty infiltration (FI) of the pancreas using area-based assessment on computed tomography (CT) (CT area-based assessment) in its correlation and agreement/concordance with histopathology-based assessment. Furthermore, we examined whether CT area-based assessment was better than CT attenuation index-based assessment. We retrospectively evaluated the degree of FI of the pancreas in 37 pancreatic cancer patients who had undergone preoperative CT and pancreaticoduodenectomy. The degree of FI of the pancreas was examined by histopathology-based assessment using surgical resection samples, and CT area-based and CT attenuation index-based assessments. Mean values of pancreatic FI measured by area-based assessment on unenhanced CT and by histopathology-based assessments were 14.4 ± 23.2 % (range 0-77.7 %) and 16.2 ± 17.4 % (range 0.2-60.2 %), respectively. Area-based assessment on unenhanced CT showed higher correlation and concordance with histopathology-based assessment, demonstrating a Spearman correlation coefficient of 0.78 (P assessment, the corresponding values were -0.66 (P assessment is suggested to be better than CT attenuation index-based assessment.

    Cashmore, Matthew; Richardson, Tim; Hilding-Ryedvik, Tuija


    to sharpen effectiveness evaluation theory for impact assessment instruments this article critically examines the neglected issue of their political constitution. Analytical examples are used to concretely explore the nature and significance of the politicisation of impact assessment. It is argued...... that raising awareness about the political character of impact assessment instruments, in itself, is a vital step in advancing effectiveness evaluation theory. Broader theoretical lessons on the framing of evaluation research are also drawn from the political analysis. We conclude that, at least within......The central role of impact assessment instruments globally in policy integration initiatives has been cemented in recent years. Associated with this trend, but also reflecting political emphasis on greater accountability in certain policy sectors and a renewed focus on economic competitiveness...

  2. A Critical Assessment of Child Custody Evaluations: Limited Science and a Flawed System. (United States)

    Emery, Robert E; Otto, Randy K; O'Donohue, William T


    -Most parents who live apart negotiate custody arrangements on their own or with the help of lawyers, mediators, or other professionals. However, psychologists and other mental health professionals increasingly have become involved in evaluating children and families in custody disputes, because of the large number of separated, divorced, and never-married parents and the substantial conflict that often accompanies the breakup of a family. Theoretically, the law guides and controls child custody evaluations, but the prevailing custody standard (the "best interests of the child" test) is a vague rule that directs judges to make decisions unique to individual cases according to what will be in children's future (and undefined) best interests. Furthermore, state statutes typically offer only vague guidelines as to how judges (and evaluators) are to assess parents and the merits of their cases, and how they should ultimately decide what custody arrangements will be in a child's best interests. In this vacuum, custody evaluators typically administer to parents and children an array of tests and assess them through less formal means including interviews and observation. Sadly, we find that (a) tests specifically developed to assess questions relevant to custody are completely inadequate on scientific grounds; (b) the claims of some anointed experts about their favorite constructs (e.g., "parent alienation syndrome") are equally hollow when subjected to scientific scrutiny; (c) evaluators should question the use even of well-established psychological measures (e.g., measures of intelligence, personality, psychopathology, and academic achievement) because of their often limited relevance to the questions before the court; and (d) little empirical data exist regarding other important and controversial issues (e.g., whether evaluators should solicit children's wishes about custody; whether infants and toddlers are harmed or helped by overnight visits), suggesting a need for

    Malon, Michelle; Cortes, Dina; Greisen, Gorm Ole


    We introduced video-based teaching in pediatrics. We evaluated the impact of a pediatric video program on student performance in assessing pediatric patients presented as video cases. The program consisted of a library of pediatric videos, and inclusion of these in the teaching and examination for pediatric medicine. Medical students on a pediatric clerkship at the University of Copenhagen assessed eight short pediatric video cases during autumn 2011 and spring 2012. Two independent observers evaluated a subset of records in a pilot study. A blind evaluation was made of the written records of 37 students before, and 58 students after, the introduction of the program using a Rubric score with four domains. The intraobserver interclass correlation coefficient was 0.94 and the interobserver interclass correlation was 0.71(n=25). The students' mean total Rubric score in spring 2012 (7.0) was significantly higher (ppediatric patients presented as video cases after the introduction of the program. The impact on real-life situations remains to be established.

  6. Evaluation of Acne Scars: How to Assess Them and What to Tell the Patient. (United States)

    Fife, Douglas


    The prevalence and emotional impact of acne scarring are underestimated by the medical community. Dermatology providers should be able to evaluate the acne scar patient and discuss treatment options. Important aspects of the patient history include current treatments, prior acne scar procedures, and the patient's goals for treatment. During the physical examination, the scars are assessed and classified by scar morphology and overall severity of scarring. Finally, a treatment plan is developed in which the most appropriate procedures are matched with the scars that will work the best. Helping the patient understand likely expectations for improvement will increase overall satisfaction. Copyright © 2016 Elsevier Inc. All rights reserved.

    Daghfous, Hafaoua; El Ayeb, Wejdène; Alouane, Leila; Tritar, Fatma


    Malnutrition and cachexia were a frequent problem in lung cancer and increases the risks of morbidity and mortality in these patients. Bioelectrical impedance analysis (BIA) is easy, non-invasive and reproducible method that can be performed. Evaluate nutritional status in patients with primary lung cancer by Mini Nutritional Assessment (MNA), BIA and anthropometric values (weight, arm and calf circumferences) and correlate the nutritional parameters to severity of cancer and histopathology. The nutritional status of 73 cases of primary lung cancer was evaluated by anthropometric parameters, MNA test and impedencemetrie Results: According to body mass index (BMI), malnutrition, overweight and obesity were noted in 34,2%, 13,7% and 5,5%. According to BMI, free-fat mass index (FFMI) and fat mass index (FMI), the investigations occurred malnutrition and depletion of muscle in respectively 19,2% and 23,3% of cases. Fat depletion was noted in 21,9%. Overweight and obesity were detected in 6,8% and 5,5% of cases. Assessment by MNA, revealed that 28,7% of patients were already malnourished and 49,3% of patients were at risk of malnutrition. A significant correlation existed between the score of MNA and arm and calf circumferences, FFMI and FMI. FMI was significantly lower in group of patients with small lung carcinoma. Only FFMI allows early detection of malnutrition in cancer patients overestimated by measuring BMI and arm circumference was the better indicator of depletion of muscle.

  9. A brief review and evaluation of earthworm biomarkers in soil pollution assessment. (United States)

    Shi, Zhiming; Tang, Zhiwen; Wang, Congying


    Earthworm biomarker response to pollutants has been widely investigated in the assessment of soil pollution. However, whether and how the earthworm biomarker-approach can be actually applied to soil pollution assessment is still a controversial issue. This review is concerned about the following points: 1. Despite much debate, biomarker is valuable to ecotoxicology and biomarker approach has been properly used in different fields. Earthworm biomarker might be used in different scenarios such as large-scale soil pollution survey and soil pollution risk assessment. Compared with physicochemical analysis, they can provide more comprehensive and straightforward information about soil pollution at low cost. 2. Although many earthworm species from different ecological categories have been tested, Eisenia fetida/andrei is commonly used. Many earthworm biomarkers have been screened from the molecular to the individual level, while only a few biomarkers, such as avoidance behavior and lysosomal membrane stability, have been focused on. Other aspects of the experimental design were critically reviewed. 3. More studies should focus on determining the reliability of various earthworm biomarkers in soil pollution assessment in future research. Besides, establishing a database of a basal level of each biomarker, exploring biomarker response in different region/section/part of earthworm, and other issues are also proposed. 4. A set of research guideline for earthworm biomarker studies was recommended, and the suitability of several earthworm biomarkers was briefly evaluated with respect to their application in soil pollution assessment. This review will help to promote further studies and practical application of earthworm biomarker in soil pollution assessment.

  10. The assessment and evaluation of low-frequency noise near the region of infrasound

    Directory of Open Access Journals (Sweden)

    Stanislav Ziaran


    Full Text Available The main aim of this paper is to present recent knowledge about the assessment and evaluation of low-frequency sounds (noise and infrasound, close to the threshold of hearing, and identify their potential effect on human health and annoyance. Low-frequency noise generated by air flowing over a moving car with an open window was chosen as a typical scenario which can be subjectively assessed by people traveling by automobile. The principle of noise generated within the interior of the car and its effects on the comfort of the driver and passengers are analyzed at different velocities. An open window of a car at high velocity behaves as a source of specifically strong tonal low-frequency noise which is generally perceived as annoying. The interior noise generated by an open window of a passenger car was measured under different conditions: Driving on a highway and driving on a typical roadway. First, an octave-band analysis was used to assess the noise level and its impact on the driver′s comfort. Second, a fast Fourier transform (FFT analysis and one-third octave-band analysis were used for the detection of tonal low-frequency noise. Comparison between two different car makers was also done. Finally, the paper suggests some possibilities for scientifically assessing and evaluating low-frequency sounds in general, and some recommendations are introduced for scientific discussion, since sounds with strong low-frequency content (but not only strong engender greater annoyance than is predicted by an A-weighted sound pressure level.

Second, a fast Fourier transform (FFT) analysis and one-third octave-band analysis were used for the detection of tonal low-frequency noise. Comparison between two different car makers was also done. Finally, the paper suggests some possibilities for scientifically assessing and evaluating low-frequency sounds in general, and some recommendations are introduced for scientific discussion, since sounds with strong low-frequency content (but not only strong) engender greater annoyance than is predicted by an A-weighted sound pressure level.

  12. Evaluation of data quality of interRAI assessments in home and community care. (United States)

    Hogeveen, Sophie E; Chen, Jonathan; Hirdes, John P


    The aim of this project is to describe the quality of assessment data regularly collected in home and community, with techniques adapted from an evaluation of the quality of long-term care data in Canada. Data collected using the Resident Assessment Instrument - Home Care (RAI-HC) in Ontario and British Columbia (BC) as well as the interRAI Community Health Assessment (CHA) in Ontario were analyzed using descriptive statistics, Pearson's r correlation, and Cronbach's alpha in order to assess trends in population characteristics, convergent validity, and scale reliability. Results indicate that RAI-HC data from Ontario and BC behave in a consistent manner, with stable trends in internal consistency providing evidence of good reliability (alpha values range from 0.72-0.94, depending on the scale and province). The associations between various scales, such as those reflecting functional status and cognition, were found to be as expected and stable over time within each setting (r values range from 0.42-0.45 in Ontario and 0.41-0.43 in BC). These trends in convergent validity demonstrate that constructs in the data behave as they should, providing evidence of good data quality. In most cases, CHA data quality matches that of RAI-HC data quality and shows evidence of good validity and reliability. The findings are comparable to the findings observed in the evaluation of data from the long-term care sector. Despite an increasingly complex client population in the home and community care sectors, the results from this work indicate that data collected using the RAI-HC and the CHA are of an overall quality that may be trusted when used to inform decision-making at the organizational- or policy-level. High quality data and information are vital when used to inform steps taken to improve quality of care and enhance quality of life. This work also provides evidence that a method used to evaluate the quality of data obtained in the long-term care setting may be used to

    Energy Technology Data Exchange (ETDEWEB)

    Lu, Hongyou; Masanet, Eric; Price, Lynn


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

  14. Muscle fatigue evaluation of astronaut upper limb based on sEMG and subjective assessment (United States)

    Zu, Xiaoqi; Zhou, Qianxiang; Li, Yun


    All movements are driven by muscle contraction, and it is easy to cause muscle fatigue. Evaluation of muscle fatigue is a hot topic in the area of astronaut life support training and rehabilitation. If muscle gets into fatigue condition, it may reduce work efficiency and has an impact on psychological performance. Therefore it is necessary to develop an accurate and usable method on muscle fatigue evaluation of astronaut upper limb. In this study, we developed a method based on surface electromyography (sEMG) and subjective assessment (Borg scale) to evaluate local muscle fatigue. Fifteen healthy young male subjects participated in the experiment. They performed isometric muscle contractions of the upper limb. sEMG of the biceps brachii were recorded during the entire process of isotonic muscle contraction and Borg scales of muscle fatigue were collected in certain times. sEMG were divided into several parts, and then mean energy of each parts were calculated by the one-twelfth band octave method. Equations were derived based on the relationship between the mean energy of sEMG and Borg scale. The results showed that cubic curve could describe the degree of local muscle fatigue, and could be used to evaluate and monitor local muscle fatigue during the entire process.

  20. [The methodological assessment and qualitative evaluation of psychometric performance tests based on the example of modern tests that assess reading and spelling skills]. (United States)

    Galuschka, Katharina; Rothe, Josefine; Schulte-Körne, Gerd


    This article looks at a means of objectively evaluating the quality of psychometric tests. This approach enables users to evaluate psychometric tests based on their methodological characteristics, in order to decide which instrument should be used. Reading and spelling assessment tools serve as examples. The paper also provides a review of German psychometric tests for the assessment of reading and spelling skills. This method facilitates the identification of psychometric tests.of high methodological quality which can be used for the assessment of reading and spelling skills. Reading performance should ideally be assessed with the following instruments: ELFE 1-6, LGVT 6-12, LESEN 6-7, LESEN 8-9, or WLLP-R. The tests to be used for the evaluation of spelling skills are DERET 1-2+, DERET 3-4+, WRT 1+, WRT 2+, WRT 3+, WRT 4+ or HSP 1-10.

  2. Assessment and evaluation of science process skills in secondary school biology laboratories (United States)

    Kujawinski, Daniel Bernard

    Awareness of the importance of process skills in science education has increased, but practical methods of assessing student performance of these skills has received minimal attention. The purpose of this dissertation is to examine how student science process skills may be accurately and reliably measured and evaluated. A set of laboratory activities that emphasized process skills was developed by 12 science educators from the western New York area who were participants in a summer institute sponsored by the Howard Hughes Medical Institute. These innovative laboratory activities were designed to be used in existing secondary school biology courses by students of different ages and ability levels. Student performance in the four general process categories of planning, performing, reasoning, and communicating was broken down into twenty specific, individual science process skills deemed important to science education. Nine teacher developers used these twelve activities, entirely and/or partially with their high school biology students during the 1995-1996 school year. Two types of assessment instruments were developed and field-tested for the purpose of evaluating student self evaluation and performance of the twenty individual science process skills. The first was an inventory that asked for the students' self-evaluation of their abilities to perform each of the twenty process skills based on the current year's laboratory experiences. The second was a set of three performance tasks which assessed the twenty skills and were to be completed by the students in a laboratory setting under supervision of their classroom teacher and the researcher. During May and early June, 1996, the student self-evaluation inventory and the three performance tasks were administered to 94 students of teachers in 6 schools who developed and used the activities (HH95, experimental group) and to 126 students of teachers in 9 schools that did not use the activities (HH96, control group).

  4. Evolution of Evaluation and Assessment in Diverse Audiences in the Digital Age (United States)

    Eriksson, S. C.


    Over the past decades, researchers have learned more about how people think and act and about the social and political aspects of teaching and learning. This understanding has brought changes in researchers' and practitioners' interactions with diverse groups and individuals. This paper addresses evaluation, a process that measures the degree to which learning and project goals are met and factors contributing to or hindering outcomes. Parallels are drawn to learning assessment. The concepts of inclusion, participation, and constructivism (Mertens, 1999; Mertens and Hopson, 2006) now drive best evaluation practices for projects with persons with disabilities (AEA, 2011). This is also true in cases of other people who have been marginalized in STEM fields, e.g. women and underrepresented groups. Inclusion of these stakeholders has important implications for the validity of an evaluation, including the accuracy of results (Jacobson et al, 2012; Gill, 1999; Lee, 1999). The American Indian Higher Education Consortium's framework for indigenous groups incorporates their values and goals into evaluation design and implementation. It is feasible to include participant input in designing the questions and methods of obtaining data, ensuring that issues of access, opportunity, and power (Shuffelbeam, 2001) are taken into consideration. Geoscience projects with u-learning and m-learning provide opportunities to test these theoretical models in innovative programs such as: field work for students with physical disability; underrepresented minority, secondary students using mobile devices in contextualized learning in informal settings; and graduate students using digital maps to enhance traditional field work. This study compares program evaluation methodology of tradition learning with that of programs for diverse groups of students using digital technology.

  5. Evaluation of interobserver agreement for postoperative pain and sedation assessment in cats. (United States)

    Benito, Javier; Monteiro, Beatriz P; Beauchamp, Guy; Lascelles, B Duncan X; Steagall, Paulo V


    OBJECTIVE To evaluate agreement between observers with different training and experience for assessment of postoperative pain and sedation in cats by use of a dynamic and interactive visual analog scale (DIVAS) and for assessment of postoperative pain in the same cats with a multidimensional composite pain scale (MCPS). DESIGN Randomized, controlled, blinded study. ANIMALS 45 adult cats undergoing ovariohysterectomy. PROCEDURES Cats received 1 of 3 preoperative treatments: bupivacaine, IP; meloxicam, SC with saline (0.9% NaCl) solution, IP, (positive control); or saline solution only, IP (negative control). All cats received premedication with buprenorphine prior to general anesthesia. An experienced observer (observer 1; male; native language, Spanish) used scales in English, and an inexperienced observer (observer 2; female; native language, French) used scales in French to assess signs of sedation and pain. Rescue analgesia was administered according to MCPS scoring by observer 1. Mean pain and sedation scores per treatment and time point, proportions of cats in each group with MCPS scores necessitating rescue analgesia, and mean MCPS scores assigned at the time of rescue analgesia were compared between observers. Agreement was assessed by intraclass correlation coefficient determination. Percentage disagreement between observers on the need for rescue analgesia was calculated. RESULTS Interobserver agreements for pain scores were good, and that for sedation scores was fair. On the basis of observer 1's MCPS scores, a greater proportion of cats in the negative control group received rescue analgesia than in the bupivacaine or positive control groups. Scores from observer 2 indicated a greater proportion of cats in the negative control group than in the positive control group required rescue analgesia but identified no significant difference between the negative control and bupivacaine groups for this variable. Overall, disagreement regarding need for rescue

    Harry, T [Oregon State University, Corvallis, OR (United States); University of California, San Diego, La Jolla, CA (United States); Manger, R; Cervino, L; Pawlicki, T [University of California, San Diego, La Jolla, CA (United States)


    Purpose: To evaluate the differences between the Veteran Affairs Healthcare Failure Modes and Effect Analysis (HFMEA) and the AAPM Task Group 100 Failure and Effect Analysis (FMEA) risk assessment techniques in the setting of a stereotactic radiosurgery (SRS) procedure were compared respectively. Understanding the differences in the techniques methodologies and outcomes will provide further insight into the applicability and utility of risk assessments exercises in radiation therapy. Methods: HFMEA risk assessment analysis was performed on a stereotactic radiosurgery procedure. A previous study from our institution completed a FMEA of our SRS procedure and the process map generated from this work was used for the HFMEA. The process of performing the HFMEA scoring was analyzed, and the results from both analyses were compared. Results: The key differences between the two risk assessments are the scoring criteria for failure modes and identifying critical failure modes for potential hazards. The general consensus among the team performing the analyses was that scoring for the HFMEA was simpler and more intuitive then the FMEA. The FMEA identified 25 critical failure modes while the HFMEA identified 39. Seven of the FMEA critical failure modes were not identified by the HFMEA and 21 of the HFMEA critical failure modes were not identified by the FMEA. HFMEA as described by the Veteran Affairs provides guidelines on which failure modes to address first. Conclusion: HFMEA is a more efficient model for identifying gross risks in a process than FMEA. Clinics with minimal staff, time and resources can benefit from this type of risk assessment to eliminate or mitigate high risk hazards with nominal effort. FMEA can provide more in depth details but at the cost of elevated effort.

  7. A process evaluation of systematic risk and needs assessment for caregivers in specialised palliative care. (United States)

    Thomsen, Kia Toft; Guldin, Mai-Britt; Nielsen, Mette Kjærgaard; Ollars, Chaitali Laura; Jensen, Anders Bonde


    Caregiving is strenuous and it may be associated with adverse psychological outcomes. During the palliative care trajectory, there are unique opportunities for providing support and preventing poor bereavement outcome. However, the tasks of palliative care staff in relation to caregivers are often unclear in the daily practice. Assessment is recommended to establish risk and needs and standards for caregiver support are available. Still, the feasibility of applying these standards among caregivers in everyday clinical practice has not been tested so far. This study tested the feasibility of an intervention based on key elements of the "Bereavement support standards for specialist palliative care services" in a Danish specialised palliative home care team. We followed the UK Medical Research Council's guidelines for the process evaluation of complex interventions. The intervention consisted of: 1. Systematic risk and needs assessment for caregivers at care entry; 2. Interdisciplinary conference to prepare a support plan; 3. Targeted support; 4. The establishment of an electronic medical record for caregivers to document targeted support. Outcomes included the reach, fidelity and acceptability of the intervention as well as the assessment of contextual factors. The intervention reached 76 of 164 caregivers (46%). The interdisciplinary risk assessment and documentation of a support plan was conducted in 57 (75%) of the enrolled caregivers. Finally, a separate medical record was established according to the intervention blueprint for 62% of caregivers receiving targeted support. After managing initial challenges, palliative care staff reported that the intervention was useful and acceptable. The intervention proved feasible and useful. Still, we identified barriers to the implementation which should be taken into consideration when planning implementation of a systematic risk and needs assessment and in the establishment of medical records for caregivers.

  9. Using performance-based assessments to evaluate parity between a campus and distance education pathway. (United States)

    Lenz, Thomas L; Monaghan, Michael S; Wilson, Amy F; Tilleman, Jennifer A; Jones, Rhonda M; Hayes, Mary M


    To compare the performance of campus-based students with that of distance students during the first 2 years of a doctor of pharmacy program to evaluate parity between the pathways. Twelve cases were created for each year of the program along with performance criteria. The cases were converted into computer-based simulations for programmatic assessment at the end of the 2002-2003 and 2003-2004 school years. All first-professional year (P1) and second-professional year (P2) students participated in the assessments. Overall class means were calculated and used to compare student performances between campus and distance education pathways. Overall scores for the 2003 P1 class were 56.4% for the campus-based students and 62.4% for the distance students, (p = 0.002); overall scores for the 2003 P2 class were 48.8% and 55.5%, respectively (p campus and distance students were 59.0% and 65.7%, respectively, (p = 0.001); and for 2004 P2 scores the results were 51.8% and 56.5%, respectively (p = 0.049). Students receiving their pharmacy education via a distance pathway scored higher on performance-based assessments compared with students receiving their pharmacy education via the traditional campus-based pathway. This indicates that distance students are receiving at least an equivalent curricular experience in the P1 and P2 years compared to that received by campus-based students.

  10. Assessment in Kinship Foster Care: A New Tool to Evaluate the Strengths and Weaknesses

    Directory of Open Access Journals (Sweden)

    Nuria Fuentes-Peláez


    Full Text Available Placement in kinship family has existed informally throughout time. There are many countries in which kinship family care is the most common measure used for child protection. However, it is a subject of continuous debate. One of the major issues is that kinship foster care is relied upon without carrying out an evaluation study of the family; often the child is placed directly with grandparents and uncles simply because they are direct family. This article presents an assessment tool to evaluate extended families in order to ensure the welfare of the child. The tool was created as a result of the cooperative research of 126 professionals from seven regions of Spain. The tool can identify the strengths and weaknesses of families by considering six factors: personal characteristics, the coverage of basic needs, collaboration with professionals, the family structure and dynamics, the relationship between family, child, and biological family, and, finally, the attitude towards the placement. The assessment tool is innovative and introduces the opportunity to consider the skills of the kinship foster care family, the needs of support, and which families are unfit to take care of the child. To conclude, the tool tries to overcome one of the principal disadvantages of kinship foster care: the lack of knowledge about the kinship family.

  13. Needs assessment for next generation computer-aided mammography reference image databases and evaluation studies. (United States)

    Horsch, Alexander; Hapfelmeier, Alexander; Elter, Matthias


    Breast cancer is globally a major threat for women's health. Screening and adequate follow-up can significantly reduce the mortality from breast cancer. Human second reading of screening mammograms can increase breast cancer detection rates, whereas this has not been proven for current computer-aided detection systems as "second reader". Critical factors include the detection accuracy of the systems and the screening experience and training of the radiologist with the system. When assessing the performance of systems and system components, the choice of evaluation methods is particularly critical. Core assets herein are reference image databases and statistical methods. We have analyzed characteristics and usage of the currently largest publicly available mammography database, the Digital Database for Screening Mammography (DDSM) from the University of South Florida, in literature indexed in Medline, IEEE Xplore, SpringerLink, and SPIE, with respect to type of computer-aided diagnosis (CAD) (detection, CADe, or diagnostics, CADx), selection of database subsets, choice of evaluation method, and quality of descriptions. 59 publications presenting 106 evaluation studies met our selection criteria. In 54 studies (50.9%), the selection of test items (cases, images, regions of interest) extracted from the DDSM was not reproducible. Only 2 CADx studies, not any CADe studies, used the entire DDSM. The number of test items varies from 100 to 6000. Different statistical evaluation methods are chosen. Most common are train/test (34.9% of the studies), leave-one-out (23.6%), and N-fold cross-validation (18.9%). Database-related terminology tends to be imprecise or ambiguous, especially regarding the term "case". Overall, both the use of the DDSM as data source for evaluation of mammography CAD systems, and the application of statistical evaluation methods were found highly diverse. Results reported from different studies are therefore hardly comparable. Drawbacks of the DDSM

  14. An Indian adaptation of the Involvement Evaluation Questionnaire: similarities and differences in assessment of caregiver burden. (United States)

    Grover, S; Chakrabarti, S; Ghormode, D; Dutt, A; Kate, N; Kulhara, P


    The Involvement Evaluation Questionnaire (IEQ) is a comprehensive, conceptually valid and reliable means of assessing caregiver burden. However, its psychometric properties have rarely been examined in non-European settings. The aim of the present study was to evaluate the psychometric properties of an Indian translation of the IEQ (Hindi-IEQ). The European Union (English) version of IEQ was translated into Hindi and reviewed by a group of experts and caregivers for translation accuracy, cultural appropriateness, and for relevance and acceptability of items and constructs. The Hindi-IEQ was then administered to 162 primary caregivers of patients with severe mental illnesses. Eighteen caregivers completed both the English and Hindi versions to check the level of agreement between them. Another 27 completed the Hindi-IEQ twice, a week apart, to evaluate its test-retest reliability. Factor structure of the Hindi-IEQ was examined using an exploratory, principal components and factor analysis. Pearson's correlation coefficients were significant for 24 items, while intraclass correlation coefficients were significant for 28 of the 31 items (P Hindi and English versions. Test-retest reliability for all items of the Hindi-IEQ was adequate, with kappa values ranging from 0.46 to 0.95 and intraclass correlation coefficients from 0.76 to 1.00. Internal consistency (Cronbach's alpha = 0.89) and the split-half reliability (Spearman-Brown coefficient = 0.68) of the Hindi-IEQ were also satisfactory. However, several differences were noted in the factor structure and distribution of scores of the Hindi-IEQ, which were quite unlike that of the European Union version. The similarities and differences between the 2 versions of the IEQ indicated that sociocultural factors could influence assessment of caregiver burden across different cultures.

  15. Development and Evaluation of a Wearable Device for Sleep Quality Assessment. (United States)

    Kuo, Chih-En; Liu, Yi-Che; Chang, Da-Wei; Young, Chung-Ping; Shaw, Fu-Zen; Liang, Sheng-Fu


    In this study, a wearable actigraphy recording device with low sampling rate (1 Hz) for power saving and data reduction and a high accuracy wake-sleep scoring method for the assessment of sleep were developed. The developed actigraphy recorder was successfully applied to overnight recordings of 81 subjects with simultaneous polysomnography (PSG) measurements. The total length of recording reached 639.8 h. A wake-sleep scoring method based on the concept of movement density evaluation and adaptive windowing was proposed. Data from subjects with good (N = 43) and poor (N = 16) sleep efficiency (SE) in the range of 52.7-97.42% were used for testing. The Bland-Altman technique was used to evaluate the concordance of various sleep measurements between the manual PSG scoring and the proposed actigraphy method. For wake-sleep staging, the average accuracy, sensitivity, specificity, and kappa coefficient of the proposed system were 92.16%, 95.02%, 71.30%, and 0.64, respectively. For the assessment of SE, the accuracy of classifying the subject with good or poor SE reached 91.53%. The mean biases of SE, sleep onset time, wake after sleep onset, and total sleep time were -0.95%, 0.74 min, 2.84 min, and -4.3 min, respectively. These experimental results demonstrate the robustness and reliability of our method using limited activity information to estimate wake-sleep stages during overnight recordings. The results suggest that the proposed wearable actigraphy system is practical for the in-home screening of objective sleep measurements and objective evaluation of sleep improvement after treatment.

  16. Design and evaluation of a low-cost instrumented glove for hand function assessment. (United States)

    Oess, Ninja P; Wanek, Johann; Curt, Armin


    The evaluation of hand function impairment following a neurological disorder (stroke and cervical spinal cord injury) requires sensitive, reliable and clinically meaningful assessment tools. Clinical performance measures of hand function mainly focus on the accomplishment of activities of daily living (ADL), typically rather complex tasks assessed by a gross ordinal rating; while the motor performance (i.e. kinematics) is less detailed. The goal of this study was to develop a low-cost instrumented glove to capture details in grasping, feasible for the assessment of hand function in clinical practice and rehabilitation settings. Different sensor types were tested for output signal stability over time by measuring the signal drift of their step responses. A system that converted sensor output voltages into angles based on pre-measured curves was implemented. Furthermore, the voltage supply of each sensor signal conditioning circuit was increased to enhance the sensor resolution. The repeatability of finger bending trajectories, recorded during the performance of three ADL-based tasks, was established using the intraclass correlation coefficient (ICC). Moreover, the accuracy of the glove was evaluated by determining the agreement between angles measured with the embedded sensors and angles measured by traditional goniometry. In addition, the feasibility of the glove was tested in four patients with a pathological hand function caused by a cervical spinal cord injury (cSCI). A sensor type that displayed a stable output signal over time was identified, and a high sensor resolution of 0.5° was obtained. The evaluation of the glove's reliability yielded high ICC values (0.84 to 0.92) with an accuracy error of about ± 5°. Feasibility testing revealed that the glove was sensitive to distinguish different levels of hand function impairment in cSCI patients. The device satisfied the desired system requirements in terms of low cost, stable sensor signal over time, full

    Full Text Available Abstract Background The evaluation of hand function impairment following a neurological disorder (stroke and cervical spinal cord injury requires sensitive, reliable and clinically meaningful assessment tools. Clinical performance measures of hand function mainly focus on the accomplishment of activities of daily living (ADL, typically rather complex tasks assessed by a gross ordinal rating; while the motor performance (i.e. kinematics is less detailed. The goal of this study was to develop a low-cost instrumented glove to capture details in grasping, feasible for the assessment of hand function in clinical practice and rehabilitation settings. Methods Different sensor types were tested for output signal stability over time by measuring the signal drift of their step responses. A system that converted sensor output voltages into angles based on pre-measured curves was implemented. Furthermore, the voltage supply of each sensor signal conditioning circuit was increased to enhance the sensor resolution. The repeatability of finger bending trajectories, recorded during the performance of three ADL-based tasks, was established using the intraclass correlation coefficient (ICC. Moreover, the accuracy of the glove was evaluated by determining the agreement between angles measured with the embedded sensors and angles measured by traditional goniometry. In addition, the feasibility of the glove was tested in four patients with a pathological hand function caused by a cervical spinal cord injury (cSCI. Results A sensor type that displayed a stable output signal over time was identified, and a high sensor resolution of 0.5° was obtained. The evaluation of the glove's reliability yielded high ICC values (0.84 to 0.92 with an accuracy error of about ± 5°. Feasibility testing revealed that the glove was sensitive to distinguish different levels of hand function impairment in cSCI patients. Conclusions The device satisfied the desired system requirements

    Ogasawara, Eiko; Shiihara, Yasufumi; Ando, Michiyo


    To develop and evaluate a self-care assessment inventory for workers (SCAI-W). A study using a self-care assessment inventory for workers consisting of 27 self-care items, the Japanese version of the Beck Depression Inventory (BDI), and the Japanese version of the University of Wales Institute of Science and Technology Mood Adjective Checklist (JUMACL) was conducted. These questionnaires were distributed to 2297 workers. There were 893 valid responses (39.9%, 584 men and 309 women, mean age 37.2±10.2 years). Three primary and eight secondary factors were established for the conceptual structure of self-care and validated by structural equation modeling. "Positive attitude" comprised the secondary factors, "hope" and "sense of fulfillment", and was influenced by another secondary factor, "social support". "Positive attitude" contributed to "attitude toward health". "Attitude toward health" comprised the secondary factors, "care about one's health" and "correction of bad habits". "Attitude toward health" influenced a primary factor, "everyday behavior", comprised of "wakefulness", "eating in moderation", and "lack of self-control". The primary factors "positive attitude" and "everyday behavior" influenced the BDI scores. A multiple regression analysis indicated that JUMACL subscale scores (energetic arousal and tense arousal), demographic data (living alone, sex, and age) and health-related data (exercise, smoking, body mass index, drinking more than three alcoholic drinks/day, and gambling) predicted the scores of the self-care assessment inventory for workers. This assessment inventory could be a useful measure of workers' self-care because it establishes a relationship between psychological and behavioral concepts that are important for health promotion. © 2012 The Authors.

    Heart disease is the leading cause of death for women in the United States. Research has identified that women are less likely than men to receive medical interventions for the prevention and treatment of heart disease. As part of a campaign to educate healthcare professionals, 1245 healthcare professionals in 11 states attended a structured 1-hour continuing medical education (CME) program based on the 2004 AHA Evidence-Based Guidelines for Cardiovascular Disease Prevention in Women and completed a pretest and posttest evaluation. We identified significant knowledge deficits in the pretest: 45% of attendees would initially recommend lifestyle changes alone, rather than statin therapy, for women diagnosed with coronary artery disease (CAD); 38% identified statin therapy as less effective in women compared with men for preventing CAD events; 27% identified Asian American women at low risk (rather than high risk) for type 2 diabetes mellitus (DM); and 21% identified processed meat (rather than baked goods) as the principal dietary source of trans fatty acids. Overall, healthcare professionals answered 5.1 of 8 knowledge questions correctly in the pretest, improving to 6.8 questions in the posttest (p < 0.001). Family physicians, obstetrician/gynecologists, general internists, nurse practitioners/physician assistants, and registered nurses all statistically significantly improved knowledge and self-assessed skills and attitudes as measured by the posttest. Significant knowledge deficits are apparent in a cross-section of healthcare providers attending a CME lecture on women and heart disease. A 1-hour presentation was successful in improving knowledge and self-assessed skills and attitudes among primary care physicians, nurse practitioners, physician assistants, and registered nurses.

    Dwarkasing, Roy S; Verschuuren, Sylvia I; van Leenders, Geert J L H; Braun, Loes M M; Krestin, Gabriel P; Schouten, W Rudolph


    The purpose of this study was to assess the a priori chance that primary cystic lesions of the retrorectal space are malignant and to investigate MRI characteristics that indicate malignancy. Patients referred to a center for colorectal surgery were recruited from 2000 to 2014. Lesions were proven by clinical assessment and histopathology. MRI was performed at 1.5 T with examinations evaluated by two radiologists. Interobserver agreement was assessed (Cohen kappa) and differences between malignant and benign lesions calculated (Fisher exact test). Twenty-eight patients (22 women, six men; age range, 18-70 years) with 31 lesions were included. Lesions were categorized as tailgut cysts (n = 16, 52%), teratomas (n = 9, 29%), lesions of colorectal origin (n = 4, 13%), or neurogenic lesions (n = 2, 6%). Five patients (18%) had malignant lesions. Colorectal lesions had the highest percentage of malignancy (3/4, 75%). A solid tissue component was found in all five (100%) malignant lesions and two (8%) of the benign lesions, which were both teratomas (p debris, septa, and wall thickening, differences were not significant. Interobserver agreement was excellent (κ = 1) for all characteristics except debris (κ = 0.795). The majority of retrorectal cystic lesions are benign. The presence of a solid tissue component should raise suspicion for malignancy.

  1. Environmental assessment for the satellite power system concept development and evaluation program: atmospheric effects

    Energy Technology Data Exchange (ETDEWEB)

    Rote, D.M.; Brubaker, K.L.; Lee, J.L.


    The US Department of Energy (DOE) has undertaken a preliminary, three-year program to investigate the impacts of the construction and operation of a satellite power system, of unprecedented scale. The Department of Energy's program, titled The Concept Development and Evaluation Program, focused its investigations on a Reference System description that calls for the use of either silicon (Si) or gallium aluminum-arsenide (GaAlAs) photovoltaic cells on 60 satellites to be constructed in GEO over a 30-yr period. Rectennas would be constructed on the ground to receive microwave energy from the satellites. Each satellite-rectenna pair is designed to produce 5 GW of power on an essentially continuous basis for use as a baseload power source for an electric power distribution system. The environmental assessment part of the program was divided into five interdependent task areas. The present document constitutes the final technical report on one of the five task areas, the Assessment of the Atmospheric Effects, and as such presents an in-depth summary of work performed during the assessment program. The issues associated with SPS activities in the troposphere are examined. These include tropospheric weather modification related to rectenna operations and rocket launches, and air quality impacts related to rocketlaunch ground clouds. Then progressing upward through the various levels of the atmosphere, the principal middle and upper atmospheric effects associated with rocket effluents are analyzed. Finally, all of the potential SPS atmospheric effects are summarized.

  2. Evaluation of Automated Fracture Risk Assessment Based on the Canadian Association of Radiologists and Osteoporosis Canada Assessment Tool. (United States)

    Allin, Sonya; Bleakney, Robert; Zhang, Julie; Munce, Sarah; Cheung, Angela M; Jaglal, Susan


    Fracture risk assessments are not always clearly communicated on bone mineral density (BMD) reports; evidence suggests that structured reporting (SR) tools may improve report clarity. The aim of this study is to compare fracture risk assessments automatically assigned by SR software in accordance with Canadian Association of Radiologists and Osteoporosis Canada (CAROC) recommendations to assessments from experts on narrative BMD reports. Charts for 500 adult patients who recently received a BMD exam were sampled from across University of Toronto's Joint Department of Medical Imaging. BMD measures and clinical details were manually abstracted from charts and were used to create structured reports with assessments generated by a software implementation of CAROC recommendations. CAROC calculations were statistically compared to experts' original assessments using percentage agreement (PA) and Krippendorff's alpha. Canadian FRAX calculations were also compared to experts', where possible. A total of 25 (5.0%) reported assessments did not conform to categorizations recommended by Canadian guidelines. Across the remainder, the Krippendorff's alpha relating software assigned assessments to physicians was high at 0.918; PA was 94.3%. Lower agreement was associated with reports for patients with documented modifying factors (alpha = 0.860, PA = 90.2%). Similar patterns of agreement related expert assessments to FRAX calculations, although statistics of agreement were lower. Categories of disagreement were defined by (1) gray areas in current guidelines, (2) margins of assessment categorizations, (3) dictation/transcription errors, (4) patients on low doses of steroids, and (5) ambiguous documentation of modifying factors. Results suggest that SR software can produce fracture risk assessments that agree with experts on most routine, adult BMD exams. Results also highlight situations where experts tend to diverge from guidelines and illustrate the potential for SR

  3. Evaluation of a pictorial method to assess liking of familiar fruits and vegetables among preschool children. (United States)

    Carraway-Stage, Virginia; Spangler, Hillary; Borges, Michelle; Goodell, L Suzanne


    Research suggests fruit and vegetable (FV) preferences greatly influence on FV intake. Methods for assessing children's FV preference in a reliable and valid manner are needed. The purpose of this study was to develop a practical, reliable, and valid method for evaluating FV liking among preschool-aged children using photographs. Authors formatively assessed a series of digital FV photographs and hedonic scales to develop content for the liking measure. The measure for assessment included 20 high-quality, digital photographs presenting 13 FVs. A non-gendered 5-point face scale (super yummy to super yucky) was chosen to determine level of liking. We used this measure to establish reliability (i.e., test re-test) and concurrent validity (i.e., photograph versus tasting experience) of the pictorial method. Data were analyzed using Spearman's Rho Correlation Coefficients and Wilcoxon signed-rank tests. The measure demonstrated varying levels of reliability/validity for individual FV items and the fruit scale; however, the vegetable scale and collapsed FV scale were determined to be valid measures. Authors recommended the removal of one weak pictorial fruit item (halved peach) from the fruit and FV scales to improve validity. The final recommended measure included 19 high-quality, digital photographs presenting 12 FVs. The pictorial FV measure and subscales may be useful for assessing FV liking among groups of preschool-aged children within the studied population. Additional research is needed to further validate the use of the pictorial FV measures in a larger, more generalizable sample. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Healthy People 2010 made it a priority to eliminate health disparities. We used a rapid assessment response and evaluation (RARE) to launch a program of participatory action research focused on health disparities in an urban, disadvantaged Black community serviced by a major south Florida health center. We formed partnerships with community members, identified local health disparities, and guided interventions targeting health disparities. We describe the RARE structure used to triangulate data sources and guide intervention plans as well as findings and conclusions drawn from scientific literature and epidemiological, historic, planning, clinical, and ethnographic data. Disenfranchisement and socioeconomic deprivation emerged as the principal determinants of local health disparities and the most appropriate targets for intervention.

    Loredana Meşină


    Full Text Available Introduction:Nutritional assessment gives accurate and reproducible information as regards the existence of an optimal energy metabolism: resting metabolic rate (RMR, the proportion of nutritional principles (fat, carbohydrate, protein used by the body in the basal metabolism, the intensity of effort during exercise where the maximum fat oxidation rate (MFOR is achieved. These information are used for the individualization of physical training programs and for the calorie intake adjustment in accordance with the body needs. The aim of this study is to underline once again the importance of physical activity in the weight management and to demonstrate the importance of nutritional assessment in the prescription of physical training in obese subjects.Material and methods:We investigated 43 young obese, with a mean age of 21.2 ± 3.1 years old, of which 93% were females. The subject’s evaluations consisted in: nutritional assessment (using indirect calorimetry method, maximal exercise test at baseline and the end of the study (after 6 months. After the exercise test, the subjects performed an individualized physical training with a minimum frequency of three times a week. Subject’s heart rate was monitorized during exercise by a physical therapist using a heart rate monitor (Polar F3, Finland. The dropout rate from the physical training program as part of the study was 35%, in the end remaining only 28 subjects.Results:After 6 months of individualized exercise training, we noticed a statistically significant increase of the following parameters: maximum fat oxidation rate (MFOR from 16.96±7.75 to 22.07±8.4 g/h, p=0.0043; resting metabolic rate (RMR from 2007±300.3 to 2105±290.4 kcal/day, p = 0.0026; along with the resting oxygen uptake (VO2 rest from 0.29±0.04 to 0.3±0.04 l / min, p = 0, 0035. The only parameter that has improved, but not reaching statistical significance was heart rate average at MFOR (HR_MFOR which increased from 127.1

    Bonanno Daniel


    Full Text Available Abstract Background Footwear characteristics have been linked to falls in older adults and children, and the development of many musculoskeletal conditions. Due to the relationship between footwear and pathology, health professionals have a responsibility to consider footwear characteristics in the etiology and treatment of various patient presentations. In order for health professionals and researchers to accurately and efficiently critique an individual's footwear, a valid and reliable footwear assessment tool is required. The aim of this study was to develop a simple, efficient, and reliable footwear assessment tool potentially suitable for use in a range of patient populations. Methods Consideration of previously published tools, other footwear related literature, and clinical considerations of three therapists were used to assist in the development of the tool. The tool was developed to cover fit, general features, general structure, motion control properties, cushioning, and wear patterns. A total of 15 participants (who provided two pairs of shoes each were recruited, and assessment using the scale was completed on two separate occasions (separated by 1 – 3 weeks by a physiotherapist and a podiatrist on each participant's dominant foot. Intra-rater and inter-rater reliability were evaluated using intra-class correlation coefficients (ICCs (model 2, 1 and the 95% limits of agreement (95% LOAs for continuous items, and percentage agreement and kappa (κ statistics for categorical items. Results All categorical items demonstrated high percentage agreement statistic for intra-rater (83 – 100% and inter-rater (83 – 100% comparisons. With the exception of last shape and objective measures used to categorise the adequacy of length, excellent intra-rater (ICC = 0.91 – 1.00 and inter-rater reliability (ICC = 0.90 – 1.00 was indicated for continuous items in the tool, including the motion control properties scale (0.91 – 0

    A sediment quality assessment survey was conducted in the Lavaca Bay system which has been designated a Superfund site because of elevated concentrations of mercury and other contaminants (e.g., PAHs) in the sediments. Twenty-four stations were sampled in the initial survey. Sediment pore water was extracted pneumatically and the toxicity of the pore water determined using the sea urchin fertilization and embryological development assays. Based on the results of the toxicity tests, aliquots of the toxic sediments were analyzed for metals, PAHs, and pesticides. Based on these results, several of the most toxic sites were resampled and a preliminary Toxicity Identification Evaluation (TIE) was performed with the pore water using the sea urchin fertilization test. Preliminary results indicated that the toxic components were removed by adsorption on a C-18 column but were not affected by EDTA additions and, therefore, the primary toxicants are hydrophobic in nature.

    Shizuma, Y; Zaitsu, T; Ueno, M; Ohnuki, M; Kawaguchi, Y


    To apply a self-administered assessment form about dental plaque level and gingival condition to Japanese adolescents and to examine the extent to which they can evaluate their own dental plaque and gingivae by comparing with dentists' clinical evaluation. Participants were 151 senior high school students (adolescents) who observed their own mouths and recorded dental plaque seen on their 12 anterior teeth, and gingival inflammation condition of 10 anterior interdental papillae, on a self-assessment form. Dentists clinically evaluated dental plaque using the, modified Debris Index (modified DI) and gingival condition, modified PMA index (P-index). "Recognition score" of dental plaque and gingival condition was the total number of agreement between the adolescents' self-assessment and dentists' evaluation. Proportion of agreement on dental plaque between the adolescents' self-assessment and dentists' evaluation with modified DI was 37.4%, and agreement on modified DI score 1, 2 or 3 was significantly lower than that on score 0 (Pplaque or gingival condition were significantly lower in adolescents with fair or poor modified DI or P-index than in those with good condition (Pplaque and gingival condition. Adolescents with poorer dental plaque level or gingival condition had lower recognition scores compared to those with better oral health. Improving oral health self-assessment skills could help adolescents achieve better oral health. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  13. An evaluation of EU legislation concerning risk assessment and preventive measures in occupational safety and health. (United States)

    Niskanen, Toivo; Naumanen, Paula; Hirvonen, Maria L


    The European Council Directive 89/391/EC of 12 June 1989 is concerned with the introduction of measures to encourage improvements in the occupational safety and health. For example, it deals with risk assessment and preventive measures. The Finnish legislation enacts the risk assessment and prevention measures in a similar way as the EU Directive 89/391/EC. The aim of this study was to examine: 1) the implementation of risk assessment process as a part of OSH management, and 2) the effectiveness of the OSH legislation concerned with risk assessment. The quantitative method involved an online questionnaire. The respondents were employers (N = 1478), workers (N = 1416) and occupational care (OHC) professionals' units (N = 469). Three quarters of the employer respondents and two thirds of the workers and OHC service providers felt that the EU legislative provisions have promoted the engagement of the management. According to the study, improvement is needed in ensuring the cooperation between employers and workers. The combined variables of Risk Assessment Process revealed positive impacts both on Cooperation and Management Measures and on the Concrete Preventive Measures among the employers and the workers. The combined variables of Use of Documents of Risk Assessments highlighted positive impacts on both the Exploiting of Results of Risk Assessments in Planning and Management and on the Exploiting of Results of Risk Assessment in Cooperation and Technology.

    Full Text Available Introduction Evaluation of sit-to-stand and stand-to-sit activities is used by physical therapists in patients with neurological and musculoskeletal disorders. Sit-to-stand activity presents different descriptions of phases and movements; however the phases of stand-to-sit activity have not been established yet.Objectives To describe the movements during stand-to-sit activity and create an evaluation protocol.Materials and methods Stand-to-sit activity was described on anterior and lateral views based on the observation of 27 healthy subjects. The body segments chosen to analyze were feet, ankles, knees, hips, pelvis, trunk, spine, upper limbs, head and cervical spine. The movements of body segments were described as adduction and abduction, eversion and inversion, valgus and varus, neutral position and asymmetry. The protocol was assessed with questionnaires answered by 12 physiotherapists experts in the area.Results Stand-to-sit activity was divided in 4 phases: 1- "Neutral position", 2- "Pre-squat", 3- "Squat" and 4- "Stabilization". Two models of protocols were developed considering 5 body segments to the anterior view and 7 segments for the lateral view.Conclusion Stand-to-sit activity was described in 4 phases with sequential movements of each body segment. These protocols allow physiotherapists to identify unusual movements of body segments during the stand-to-sit activity.

    Farrell, Albert D; Sullivan, Terri N; Goncy, Elizabeth A; Le, Anh-Thuy H


    This study evaluated the Problem Behavior Frequency Scale (PBFS), a self-report measure designed to assess adolescents' frequency of victimization, aggression, and other problem behaviors. Analyses were conducted on a sample of 5,532 adolescents from 37 schools at 4 sites. About half (49%) of participants were male; 48% self-identified as Black non-Hispanic; 21% as Hispanic, 18% as White non-Hispanic. Adolescents completed the PBFS and measures of beliefs and values related to aggression, and delinquent peer associations at the start of the 6th grade and over 2 years later. Ratings of participants' behavior were also obtained from teachers on the Behavioral Assessment System for Children. Confirmatory factor analyses supported a 7-factor model that differentiated among 3 forms of aggression (physical, verbal, and relational), 2 forms of victimization (overt and relational), drug use, and other delinquent behavior. Support was found for strong measurement invariance across gender, sites, and time. The PBFS factors generally showed the expected pattern of correlations with teacher ratings of adolescents' behavior and self-report measures of relevant constructs.

  19. Evaluation of triclosan in Minnesota lakes and rivers: Part I - ecological risk assessment. (United States)

    Lyndall, Jennifer; Barber, Timothy; Mahaney, Wendy; Bock, Michael; Capdevielle, Marie


    Triclosan, an antimicrobial compound found in consumer products, may be introduced into the aquatic environment via residual concentrations in municipal wastewater treatment effluent. We conducted an aquatic risk assessment that incorporated the available measured triclosan data from Minnesota lakes and rivers. Although only data reported from Minnesota were considered in the risk assessment, the developed toxicity benchmarks can be applied to other environments. The data were evaluated using a series of environmental fate models to ensure the data were internally consistent and to fill any data gaps. Triclosan was not detected in over 75% of the 567 surface water and sediment samples. Measured environmental data were used to model the predicted environmental exposures to triclosan in surface water, surface sediment, and biota tissues. Toxicity benchmarks based on fatty acid synthesis inhibition and narcosis were determined for aquatic organisms based, in part, on a species sensitivity distribution of chronic toxicity thresholds from the available literature. Predicted and measured environmental concentrations for surface water, sediment, and tissue were below the effects benchmarks, indicating that exposure to triclosan in Minnesota lakes and rivers would not pose an unacceptable risk to aquatic organisms.

  20. Using dynamic assessment to evaluate the expressive syntax of children who use augmentative and alternative communication. (United States)

    King, Marika R; Binger, Cathy; Kent-Walsh, Jennifer


    The developmental readiness of four 5-year-old children to produce basic sentences using graphic symbols on an augmentative and alternative communication (AAC) device during a dynamic assessment (DA) task was examined. Additionally, the ability of the DA task to predict performance on a subsequent experimental task was evaluated. A graduated prompting framework was used during DA. Measures included amount of support required to produce the targets, modifiability (change in participant performance) within a DA session, and predictive validity of DA. Participants accurately produced target structures with varying amounts of support. Modifiability within DA sessions was evident for some participants, and partial support was provided for the measures of predictive validity. These initial results indicate that DA may be a viable way to measure young children's developmental readiness to learn how to sequence simple, rule-based messages via aided AAC.

  1. Developments in life cycle assessment applied to evaluate the environmental performance of construction and demolition wastes. (United States)

    Bovea, M D; Powell, J C


    This paper provides a review of the literature that applies the life cycle assessment (LCA) methodology to the assessment of the environmental performance of the life cycle of construction and demolition waste (CDW) management systems. This article is focused on generating a general mapping of the literature and on identifying the best practices in compliance with LCA framework and proposing directions for future LCA studies in this field. The temporal evolution of the research in this field and the aim of the studies have grown in parallel with the legal framework related to waste and energy efficiency of buildings. Most studies have been published in Europe, followed by USA. Asia and Australia, being at an incipient application stage to the rest of the world. Topics related to "LCA of buildings, including their EoL" and "LCA of general CDW management strategies" are the most frequently analysed, followed by "LCA of EoL of construction elements" and "LCA of natural material vs recycled material". Regarding the strategies, recycling off-site and incineration, both combined with landfill for the rejected fractions, are the most commonly applied. Re-use or recycling on-site is the strategy least applied. The key aspect when LCA is applied to evaluate CDW management systems is the need to normalise which processes to include in the system boundary and the functional unit, the use of inventory data adapted to the context of the case study and the definition of a common set of appropriate impact assessment categories. Also, it is important to obtain results disaggregated by unit processes. This will allow the comparison between case studies. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Quadri, Nuz; Lloyd, Andrew; Keating, Karen N; Nafees, Beenish; Piccirillo, Jay; Wild, Diane


    To validate the Sinonasal Outcome Test-16 and Activity Impairment Assessment in patients with acute bacterial sinusitis. Data were used from a phase III clinical trial designed to evaluate the efficacy and safety of moxifloxacin 400 mg once daily for 5 consecutive days in the treatment of acute bacterial sinusitis. The psychometric properties and factor structure of the 2 measures were assessed. Participants were given the measures to self-complete using either a telephone voice response system or a paper-and-pencil format. Three hundred seventy-four patients with acute bacterial sinusitis were used in the analysis. Patients received either a placebo or 400 mg moxifloxacin once daily. Patients were then reviewed at test of cure and follow-up. All analyses were conducted on a combined sample of placebo and active treatment patients. The Sinonasal Outcome Test-16 was associated with minimal missing data at baseline but a higher proportion by test of cure. There was no evidence of floor or ceiling effects and no significant skew. The Activity Impairment Assessment also had low missing data at baseline and no obvious floor or ceiling effects, but the data were not normally distributed. Both measures had good internal consistency. Convergent and divergent validity as well as sensitivity and the minimally important difference are also reported. The measures both have good psychometric properties and are suitable for use with patients with acute bacterial sinusitis. Both instruments are sensitive. The minimal important difference estimates for the Sinonasal Outcome Test-16 are quite high but are similar to estimates reported previously.

  9. Evaluation of triclosan in Minnesota lakes and rivers: Part II - human health risk assessment. (United States)

    Yost, Lisa J; Barber, Timothy R; Gentry, P Robinan; Bock, Michael J; Lyndall, Jennifer L; Capdevielle, Marie C; Slezak, Brian P


    Triclosan, an antimicrobial compound found in consumer products, has been detected in low concentrations in Minnesota municipal wastewater treatment plant (WWTP) effluent. This assessment evaluates potential health risks for exposure of adults and children to triclosan in Minnesota surface water, sediments, and fish. Potential exposures via fish consumption are considered for recreational or subsistence-level consumers. This assessment uses two chronic oral toxicity benchmarks, which bracket other available toxicity values. The first benchmark is a lower bound on a benchmark dose associated with a 10% risk (BMDL10) of 47mg per kilogram per day (mg/kg-day) for kidney effects in hamsters. This value was identified as the most sensitive endpoint and species in a review by Rodricks et al. (2010) and is used herein to derive an estimated reference dose (RfD(Rodricks)) of 0.47mg/kg-day. The second benchmark is a reference dose (RfD) of 0.047mg/kg-day derived from a no observed adverse effect level (NOAEL) of 10mg/kg-day for hepatic and hematopoietic effects in mice (Minnesota Department of Health [MDH] 2014). Based on conservative assumptions regarding human exposures to triclosan, calculated risk estimates are far below levels of concern. These estimates are likely to overestimate risks for potential receptors, particularly because sample locations were generally biased towards known discharges (i.e., WWTP effluent).

  10. Assessing the Potential Economic Viability of Precision Irrigation: A Theoretical Analysis and Pilot Empirical Evaluation

    Directory of Open Access Journals (Sweden)

    Francesco Galioto


    Full Text Available The present study explores the value generated by the use of information to rationalize the use of water resources in agriculture. The study introduces the value of information concept in the field of irrigation developing a theoretical assessment framework to evaluate whether the introduction of “Precision Irrigation” (PI practices can improve expectations on income. This is supported by a Stakeholders consultation and by a numerical example, using secondary data and crop growth models. The study reveals that the value generated with the transition to PI varies with pedo-climate, economic, technological and other conditions, and it depends on the initial status of the farmer’s information environment. These factors affect the prerequisite needed to make viable PI. To foster the adoption of PI, stakeholders envisaged the need to set up free meteorological information and advisory service that supports farmers in using PI, as well as other type of instruments. The paper concludes that the profitability of adoption and the relevant impact on the environment cannot be considered as generally given, but must be evaluated case by case justifying (or not the activation of specific agricultural policy measures supporting PI practices to target regions.

  11. Dysphagia after vertical sleeve gastrectomy: Evaluation of risk factors and assessment of endoscopic intervention. (United States)

    Nath, Anand; Yewale, Sayali; Tran, Tung; Brebbia, John S; Shope, Timothy R; Koch, Timothy R


    To evaluate the risks of medical conditions, evaluate gastric sleeve narrowing, and assess hydrostatic balloon dilatation to treat dysphagia after vertical sleeve gastrectomy (VSG). VSG is being performed more frequently worldwide as a treatment for medically-complicated obesity, and dysphagia is common post-operatively. We hypothesize that post-operative dysphagia is related to underlying medical conditions or narrowing of the gastric sleeve. This is a retrospective, single institution study of consecutive patients who underwent sleeve gastrectomy from 2013 to 2015. Patients with previous bariatric procedures were excluded. Narrowing of a gastric sleeve includes: inability to pass a 9.6 mm gastroscope due to stenosis or sharp angulation or spiral hindering its passage. Of 400 consecutive patients, 352 are included; the prevalence of dysphagia is 22.7%; 33 patients (9.3%) have narrowing of the sleeve with 25 (7.1%) having sharp angulation or a spiral while 8 (2.3%) have a stenosis. All 33 patients underwent balloon dilatation of the gastric sleeve and dysphagia resolved in 13 patients (39%); 10 patients (30%) noted resolution of dysphagia after two additional dilatations. In a multivariate model, medical conditions associated with post-operative dysphagia include diabetes mellitus, symptoms of esophageal reflux, a low whole blood thiamine level, hypothyroidism, use of non-steroidal anti-inflammatory drugs, and use of opioids. Narrowing of the gastric sleeve and gastric sleeve stenosis are common after VSG. Endoscopic balloon dilatations of the gastric sleeve resolves dysphagia in 69% of patients.

    Styliani Gewrgios Tziaferi


    Conclusion: This study confirmed the usefulness of staff participation in the risk assessment process, despite the tendency for staff to overestimate the risk level of physical hazards. The combination of combining staff perception, experts’ evaluation and objective measures in the risk assessment process increases the efficiency of risk management in the hospital environment and the enforcement of relevant legislation.

  14. Retrospective evaluation of the impact of functional immunotoxicity testing on pesticide hazard identification and risk assessment. (United States)

    Gehen, Sean C; Blacker, Ann M; Boverhof, Darrell R; Hanley, Thomas R; Hastings, Charles E; Ladics, Gregory S; Lu, Haitian; O'Neal, Fredrick O


    Conduct of a T-cell-dependent antibody response (TDAR) assay in rodents according to Environmental Protection Agency (EPA) Test Guideline OPPTS 870.7800 is now required for chemical pesticide active ingredients registered in the United States. To assess potential regulatory impact, a retrospective analysis was developed using TDAR tests conducted on 78 pesticide chemicals from 46 separate chemical classes. The objective of the retrospective analysis was to examine the frequency of positive responses and determine the potential for the TDAR to yield lower endpoints than those utilized to calculate reference doses (RfDs). A reduction in the TDAR response was observed at only the high-dose level in five studies, while it was unaltered in the remaining studies. Importantly, for all 78 pesticide chemicals, the TDAR no-observed-adverse-effect levels (TDAR NOAELs) were greater than the NOAELS currently in use as risk assessment endpoints. The TDAR NOAELs were higher than the current EPA-selected endpoints for the chronic RfD, short-term, intermediate and long-term exposure scenarios by 3-27,000, 3-1,688, 3-1,688 and 4.9-1,688 times, respectively. Based on this analysis, conduct of the TDAR assay had minimal impact on hazard identification and did not impact human health risk assessments for the pesticides included in this evaluation. These data strongly support employment of alternative approaches including initial weight-of-evidence analysis for immunotoxic potential prior to conducting functional immunotoxicity testing for pesticide active ingredients.

  15. Supporting Sustainable Markets Through Life Cycle Assessment: Evaluating emerging technologies, incorporating uncertainty and the consumer perspective (United States)

    Merugula, Laura

    As civilization's collective knowledge grows, we are met with the realization that human-induced physical and biological transformations influenced by exogenous psychosocial and economic factors affect virtually every ecosystem on the planet. Despite improvements in energy generation and efficiencies, demand of material goods and energy services increases with no sign of a slowing pace. Sustainable development requires a multi-prong approach that involves reshaping demand, consumer education, sustainability-oriented policy, and supply chain management that does not serve the expansionist mentality. Thus, decision support tools are needed that inform developers, consumers, and policy-makers for short-term and long-term planning. These tools should incorporate uncertainty through quantitative methods as well as qualitatively informing the nature of the model as imperfect but necessary and adequate. A case study is presented of the manufacture and deployment of utility-scale wind turbines evaluated for a proposed change in blade manufacturing. It provides the first life cycle assessment (LCA) evaluating impact of carbon nanofibers, an emerging material, proposed for integration to wind power generation systems as blade reinforcement. Few LCAs of nanoproducts are available in scientific literature due to research and development (R&D) for applications that continues to outpace R&D for environmental, health, and safety (EHS) and life cycle impacts. LCAs of emerging technologies are crucial for informing developers of potential impacts, especially where market growth is swift and dissipative. A second case study is presented that evaluates consumer choice between disposable and reusable beverage cups. While there are a few studies that attempt to make the comparison using LCA, none adequately address uncertainty, nor are they representative for the typical American consumer. By disaggregating U.S. power generation into 26 subregional grid production mixes and evaluating

  17. Development and evaluation of a computer adaptive test to assess anxiety in cardiovascular rehabilitation patients. (United States)

    Abberger, Birgit; Haschke, Anne; Wirtz, Markus; Kroehne, Ulf; Bengel, Juergen; Baumeister, Harald


    To develop and evaluate a computer adaptive test for the assessment of anxiety in cardiovascular rehabilitation patients (ACAT-cardio) that tailors an optimal test for each patient and enables precise and time-effective measurement. Simulation study, validation study (against the anxiety subscale of the Hospital Anxiety and Depression Scale and the physical component summary scale of the 12-Item Short-Form Health Survey), and longitudinal study (beginning and end of rehabilitation). Cardiac rehabilitation centers. Cardiovascular rehabilitation patients: simulation study sample (n=106; mean age, 57.8y; 25.5% women) and validation and longitudinal study sample (n=138; mean age, 58.6 and 57.9y, respectively; 16.7% and 12.1% women, respectively). Not applicable. Hospital Anxiety and Depression Scale, 12-Item Short-Form Health Survey, and ACAT-cardio. The mean number of items was 9.2 with an average processing time of 1:13 minutes when an SE ≤.50 was used as a stopping rule; with an SE ≤.32, there were 28 items and a processing time of 3:47 minutes. Validity could be confirmed via correlations between .68 and .81 concerning convergent validity (ACAT-cardio vs Hospital Anxiety and Depression Scale anxiety subscale) and correlations between -.47 and -.30 concerning discriminant validity (ACAT-cardio vs 12-Item Short-Form Health Survey physical component summary scale). Sensitivity to change was moderate to high with standardized response means between .45 and .82. The ACAT-cardio shows good psychometric properties and provides the opportunity for an innovative and time-effective assessment of anxiety in cardiovascular rehabilitation. A more flexible stopping rule might further improve the ACAT-cardio. Additionally, testing in other cardiovascular populations would increase generalizability.

  18. Application and interpretation of multiple statistical tests to evaluate validity of dietary intake assessment methods. (United States)

    Lombard, Martani J; Steyn, Nelia P; Charlton, Karen E; Senekal, Marjanne


    Several statistical tests are currently applied to evaluate validity of dietary intake assessment methods. However, they provide information on different facets of validity. There is also no consensus on types and combinations of tests that should be applied to reflect acceptable validity for intakes. We aimed to 1) conduct a review to identify the tests and interpretation criteria used where dietary assessment methods was validated against a reference method and 2) illustrate the value of and challenges that arise in interpretation of outcomes of multiple statistical tests in assessment of validity using a test data set. An in-depth literature review was undertaken to identify the range of statistical tests used in the validation of quantitative food frequency questionnaires (QFFQs). Four databases were accessed to search for statistical methods and interpretation criteria used in papers focusing on relative validity. The identified tests and interpretation criteria were applied to a data set obtained using a QFFQ and four repeated 24-hour recalls from 47 adults (18-65 years) residing in rural Eastern Cape, South Africa. 102 studies were screened and 60 were included. Six statistical tests were identified; five with one set of interpretation criteria and one with two sets of criteria, resulting in seven possible validity interpretation outcomes. Twenty-one different combinations of these tests were identified, with the majority including three or less tests. Coefficient of correlation was the most commonly used (as a single test or in combination with one or more tests). Results of our application and interpretation of multiple statistical tests to assess validity of energy, macronutrients and selected micronutrients estimates illustrate that for most of the nutrients considered, some outcomes support validity, while others do not. One to three statistical tests may not be sufficient to provide comprehensive insights into various facets of validity. Results of our

  19. Military Emergency Medical Service System Assessment: Application of the National Park Service Needs Assessment and Program Audit to Objectively Evaluate the Military EMS System of Okinawa, Japan. (United States)

    Ross, Elliot M; Harper, Stephen A; Cunningham, Cord; Walrath, Benjamin D; DeMers, Gerard; Kharod, Chetan U


    As part of a Military Emergency Medical Services (EMS) system process improvement initiative, the authors sought to objectively evaluate the U.S. military EMS system for the island of Okinawa. They applied a program evaluation tool currently utilized by the U.S. National Park Service (NPS). A comprehensive needs assessment was conducted to evaluate the current Military EMS system in Okinawa, Japan. The NPS EMS Program Audit Worksheet was used to get an overall "score" of our assessment. After all the data had been collected, a joint committee of Military EMS physicians reviewed the findings and made formal recommendations. From 2011 to 2014, U.S. military EMS on Okinawa averaged 1,345 ± 137 patient transports annually. An advanced life support (ALS) provider would have been dispatched on 558 EMS runs (38%) based on chief complaint in 2014 had they been available. Over 36,000 man-hours were expended during this period to provide National Registry Emergency Medical Technician (EMT)-accredited instruction to certify 141 Navy Corpsman as EMT Basics. The NPS EMS Program Audit Worksheet was used and the program scored a total of 31, suggesting the program is well planned and operating within standards. This evaluation of the Military EMS system on Okinawa using the NPS program assessment and audit worksheet demonstrates the NPS evaluation instruments may offer a useful assessment tool for the evaluation of Military EMS systems.

    Rao, D D; Baburajan, A; Sudheendran, V; Verma, P C; Hegde, A G


    The evaluation and assessment of monitoring data generated over a period of 1983-2007 (25 years) of a nuclear facility is presented. Time trends of particulate radioactivity, correlation between (137)Cs in discharge canal seawater and station discharged activity and correlation of (137)Cs, (60)Co, and (131)I in marine species such as sponge and Nerita (gastropod) and corresponding discharged activity are discussed. The concentration of (137)Cs and (131)I in seawater versus biota are discussed. A good correlation between (137)Cs in seawater and (137)Cs in liquid waste discharged was observed (R(2) = 0.8, p Nerita and discharged concentration of (137)Cs, (131)I and (60)Co (R(2) = 0.55-0.73 and p < 0.001). The measurements over the years indicated that there is no accumulation of radionuclides in either the terrestrial or aquatic environments. The mean (137)Cs decreased from the pre-operational levels: 7.0-3.6 Bq kg(-1) in soil, 0.91-0.016 Bq L(-1) in milk and 0.28-0.036 Bq kg(-1) in vegetation. Similarly, the mean (90)Sr in these matrixes decreased from 3.9 to 0.26 Bq kg(-1); 0.37-0.011 Bq L(-1) and 0.34-0.022 Bq kg(-1) respectively. Cesium-137 of about 700 microBq m(-3) was measured in the air filter disks during 1986 and there was a decrease of three orders of magnitude in concentration over the 25 years. The evaluation of environmental data indicated that the radionuclide concentrations and potential impacts, in terms of effective dose to the members of public, have significantly reduced since 1969.

  5. Quality Assessment of Studies Published in Open Access and Subscription Journals: Results of a Systematic Evaluation. (United States)

    Pastorino, Roberta; Milovanovic, Sonja; Stojanovic, Jovana; Efremov, Ljupcho; Amore, Rosarita; Boccia, Stefania


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

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

    Simulation-based programs are increasingly being used to teach obstetrics and gynaecology examinations, but it is difficult to establish student learning acquired through them. Assessment may test student learning but its role in learning itself is rarely recognised. We undertook this study to assess medical and midwifery student learning through a simulation program using a pre-test and post-test design and also to evaluate use of assessment as a method of learning. The interprofessional simulation education program consisted of a brief pre-reading document, a lecture, a video demonstration and a hands-on workshop. Over a 24-month period, 405 medical and 104 midwifery students participated in the study and were assessed before and after the program. Numerical data were analysed using paired t-test and one-way analysis of variance. Students' perceptions of the role of assessment in learning were qualitatively analysed. The post-test scores were significantly higher than the pre-test (P assessment on learning in preparation of the assessment, reinforcement of learning occurring during assessment and reflection on performance cementing previous learning as a post-assessment effect. Both medical and midwifery students demonstrated a significant improvement in their test scores and for most students the examination process itself was a positive learning experience. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

  8. Evaluating Recall and Recognition Memory Using the Montreal Cognitive Assessment: Applicability for Alzheimer's and Huntington's Diseases. (United States)

    Van Liew, Charles; Santoro, Maya S; Goldstein, Jody; Gluhm, Shea; Gilbert, Paul E; Corey-Bloom, Jody


    We sought to investigate whether the Montreal Cognitive Assessment (MoCA) could provide a brief assessment of recall and recognition using Huntington disease (HD) and Alzheimer disease (AD) as disorders characterized by different memory deficits. This study included 80 participants with HD, 64 participants with AD, and 183 community-dwelling control participants. Random-effects hierarchical logistic regressions were performed to assess the relative performance of the normal control (NC), participants with HD, and participants with AD on verbal free recall, cued recall, and multiple-choice recognition on the MoCA. The NC participants performed significantly better than participants with AD at all the 3 levels of assessment. No difference existed between participants with HD and NC for cued recall, but NC participants performed significantly better than participants with HD on free recall and recognition. The participants with HD performed significantly better than participants with AD at all the 3 levels of assessment. The MoCA appears to be a valuable, brief cognitive assessment capable of identifying specific memory deficits consistent with known differences in memory profiles. © The Author(s) 2016.

    Li, Ping; Xue, Su-Yin; Wang, Sheng-Li; Nan, Zhong-Ren


    In order to evaluate the contamination and health risk of heavy metals from atmospheric deposition in Lanzhou, samples of atmospheric deposition were collected from 11 sampling sites respectively and their concentrations of heavy metals were determined. The results showed that the average contents of Cu, Pb, Cd, Cr, Ni, Zn and Mn were 82.22, 130.31, 4.34, 88.73, 40.64, 369.23 and 501.49 mg x kg(-1), respectively. There was great difference among different functional areas for all elements except Mn. According to the results, the enrichment factor score of Mn was close to 1, while the enrichment of Zn, Ni, Cu and Cr was more serious, and Pb and Cd were extremely enriched. The assessment results of geoaccumulation index of potential ecological risk indicated that the pollution of Cd in the atmospheric deposition of Lanzhou should be classified as extreme degree, and that of Cu, Ni, Zn, Pb as between slight and extreme degrees, and Cr as practically uncontaminated. Contaminations of atmospheric dust by heavy metals in October to the next March were more serious than those from April to August. Health risk assessment indicated that the heavy metals in atmospheric deposition were mainly ingested by human bodies through hand-mouth ingestion. The non-cancer risk was higher for children than for adults. The order of non-cancer hazard indexes of heavy metals was Pb > Cr > Cd > Cu > Ni > Zn. The non-cancer hazard indexes and carcinogen risks of heavy metals were both lower than their threshold values, suggesting that they will not harm the health.

    Kherkheulidze, M; Kavlashvili, N; Kandelaki, E; Manjavidze, T


    The aim of the study was assessment of the general nutrition knowledge and physical activity rate among the first grade school age children and evaluation of their diet and nutritional skills based on the parental interviews. Cross-sectional study was conducted in randomly selected schools of Tbilisi. In each school was selected one group of the second grade children and their parents by cluster selection method. A population of 290 children aged 6-8 years and their parents were interviewed. The statistical analysis was carried out by means of the SPPS 17. Questionnaires, except those with incomplete answers (n=30), were used for the analytical data. The study shows that in general, the level of knowledge related to rich sources of nutrients was poor. The most of the children can't identify the role of calcium (72,6%), proteins (68,1%) and iron (84,6 %). Children prefer to eat and select foods which they like (71,8%), such as sweets and cakes, hamburgers, chips and etc. The study showed that the most of the children (83,3%) have normal weight for age, underweight was revealed in 3,1% of children, more frequent was overweight (12,3%) and obesity (1,4%). There wasn't significant difference of overweight and underweight distribution in boys and girls. The assessment of child dietary intake show, that intake of fruits and vegetables, as well as milk and milk products is quite low, while intake of bread and pastry, and sweets and cakes are quite high. Daily consumption of sweets and snacks was significantly higher in girls (64.2%) than in boys (47.5%) (pinformation about healthy feeding (55%), lack of time for preparation of food (33%), inability to control child's feeding (36%), financial deficit (4%). The dietary intake of children does not correspond to WHO recommendations. It is recommended on the one hand to conduct country wide assessment of dietary intake of children and adolescent and on the other hand to implement nutrition education programs.

  11. GIS and Multi-criteria evaluation (MCE) for landform geodiversity assessment (United States)

    Najwer, Alicja; Reynard, Emmanuel; Zwoliński, Zbigniew


    In geomorphology, at the contemporary stage of methodology and methodological development, it is very significant to undertake new research problems, from theoretical and application point of view. As an example of applying geoconservation results in landscape studies and environmental conservation one can refer to the problem of the landform geodiversity. The concept of geodiversity was created relatively recently and, therefore, little progress has been made in its objective assessment and mapping. In order to ensure clarity and coherency, it is recommended that the evaluation process to be rigorous. Multi-criteria evaluation meets these criteria well. The main objective of this presentation is to demonstrate a new methodology for the assessment of the selected natural environment components in response to the definition of geodiversity, as well as visualization of the landforms geodiversity, using the opportunities offered by the geoinformation environment. The study area consists of two peculiar alpine valleys: Illgraben and Derborence, located in the Swiss Alps. Apart from glacial and fluvial landforms, the morphology of these two sites is largely due to the extreme phenomena(rockslides, torrential processes). Both valleys are recognized as geosites of national importance. The basis of the assessment is the selection of the geographical environment features. Firstly, six factor maps were prepared for each area: the landform energy, the landform fragmentation, the contemporary landform preservation, geological settings and hydrographic elements (lakes and streams). Input maps were then standardized and resulted from map algebra operations carried out by multi-criteria evaluation (MCE) with GIS-based Weighted Sum technique. Weights for particular classes were calculated using pair-comparison matrixes method. The final stage of deriving landform geodiversity maps was the reclassification procedure with the use of natural breaks method. The final maps of landform

    To develop and evaluate an objective method of technical skills assessment for graduating subspecialists in colorectal (CR) surgery-the Colorectal Objective Structured Assessment of Technical Skill (COSATS). It may be reasonable for the public to assume that surgeons certified as competent have had their technical skills assessed. However, technical skill, despite being the hallmark of a surgeon, is not directly assessed at the time of certification by surgical boards. A procedure-based, multistation technical skills examination was developed to reflect a sample of the range of skills necessary for CR surgical practice. These consisted of bench, virtual reality, and cadaveric models. Reliability and construct validity were evaluated by comparing 10 graduating CR residents with 10 graduating general surgery (GS) residents from across North America. Expert CR surgeons, blinded to level of training, evaluated performance using a task-specific checklist and a global rating scale. The mean global rating score was used as the overall examination score and a passing score was set at "borderline competent for CR practice." The global rating scale demonstrated acceptable interstation reliability (0.69) for a homogeneous group of examinees. Both the overall checklist and global rating scores effectively discriminated between CR and GS residents (P Technical Skill effectively discriminated between CR and GS residents. With further validation, the Colorectal Objective Structured Assessment of Technical Skill could be incorporated into the colorectal board examination where it would be the first attempt of a surgical specialty to formally assess technical skill at the time of certification.

    The aim of this study was to describe the magnetic resonance imaging (MRI) findings in patients with ischiofemoral impingement (IFI) and to evaluate the reliability of these MRI findings. Seventy hips of 50 patients with hip pain and quadratus femoris muscle (QFM) edema and 38 hips of 30 control cases were included in the study. The QFM edema and fatty replacement were assessed visually. Ischiofemoral space (IFS), quadratus femoris space (QFS), inclination angle (IA), hamstring tendon area (HTA), and total quadratus femoris muscle volume (TQFMV) measurements were performed independently by two musculoskeletal radiologists. The intra- and interobserver reliabilities were obtained for quantitative variables. IFS, QFS, and TQFMV values of the patient group were significantly lower than those of controls (P < 0.001). HTA and IA measurements of the patient group were also significantly higher than in controls (P < 0.05). The QFM fatty replacement grades were significantly higher in the patient group than in the control group (P < 0.001). Inter- and intra-observer reliabilities were strong for all continuous variables. Clinicians and radiologists should be aware of IFI in patients with hip or groin pain, and MRI should be obtained for the presence of the QFM edema/fatty replacement, narrowing of the IFS-QFS, and other features that may help in the clinical diagnosis of IFI for the proper diagnosis and treatment of the disease.

    Full Text Available With the revolution occurred in communication technologies at the beginning of 1990’s, network technologies have emerged as the challenging parameters accelerating improvements of instructional technologies. Online classrooms and management of them appeared as a new domain which necessitates a new paradigm different from the classical ones. User and instructor friendly learning context and management systems (LCMS have brought new approaches, techniques and tools for the assessment and measurement processes. These approaches, techniques and tools embedded in LCMS have redefined not only the way teachers teach but also students learn. WebCT, Blackboard and eCollege and many others as the online instructional environments have provided new opportunities to construct a coherent instructional system which has never been used as a unique environment any before. Assessment and measurement have been redefined within this framework. The successes of assessment and measurement methodologies or system inevitably depend on conceptualization and then implementation to different educational settings.

  15. A simple integrated assessment approach to global change simulation and evaluation (United States)

    Ogutu, Keroboto; D'Andrea, Fabio; Ghil, Michael


    We formulate and study the Coupled Climate-Economy-Biosphere (CoCEB) model, which constitutes the basis of our idealized integrated assessment approach to simulating and evaluating global change. CoCEB is composed of a physical climate module, based on Earth's energy balance, and an economy module that uses endogenous economic growth with physical and human capital accumulation. A biosphere model is likewise under study and will be coupled to the existing two modules. We concentrate on the interactions between the two subsystems: the effect of climate on the economy, via damage functions, and the effect of the economy on climate, via a control of the greenhouse gas emissions. Simple functional forms of the relation between the two subsystems permit simple interpretations of the coupled effects. The CoCEB model is used to make hypotheses on the long-term effect of investment in emission abatement, and on the comparative efficacy of different approaches to abatement, in particular by investing in low carbon technology, in deforestation reduction or in carbon capture and storage (CCS). The CoCEB model is very flexible and transparent, and it allows one to easily formulate and compare different functional representations of climate change mitigation policies. Using different mitigation measures and their cost estimates, as found in the literature, one is able to compare these measures in a coherent way.

  18. Evaluation of hyperspectral technology for assessing the presence and severity of peripheral artery disease. (United States)

    Chin, Jason A; Wang, Edward C; Kibbe, Melina R


    Hyperspectral imaging is a novel technology that can noninvasively measure oxyhemoglobin and deoxyhemoglobin concentrations to create an anatomic oxygenation map. It has predicted healing of diabetic foot ulcers; however, its ability to assess peripheral arterial disease (PAD) has not been studied. The aims of this study were to determine if hyperspectral imaging could accurately assess the presence or absence of PAD and accurately predict PAD severity. This prospective study included consecutive consenting patients presenting to the vascular laboratory at the Jesse Brown VA Medical Center during a 10-week period for a lower extremity arterial study, including ankle-brachial index (ABI) and Doppler waveforms. Patients with lower extremity edema were excluded. Patients underwent hyperspectral imaging at nine angiosomes on each extremity. Additional sites were imaged when tissue loss was present. Medical records of enrolled patients were reviewed for demographic data, active medications, surgical history, and other information pertinent to PAD. Patients were separated into no-PAD and PAD groups. Differences in hyperspectral values between the groups were evaluated using the two-tailed t test. Analysis for differences in values over varying severities of PAD, as defined by triphasic, biphasic, or monophasic Doppler waveforms, was conducted using one-way analysis of variance. Hyperspectral values were correlated with the ABI using a Pearson bivariate linear correlation test. The study enrolled 126 patients (252 limbs). After exclusion of 15 patients, 111 patients were left for analysis, including 46 (92 limbs) no-PAD patients and 65 (130 limbs) PAD patients. Groups differed in age, diabetes, coronary artery disease, congestive heart failure, tobacco use, and insulin use. Deoxyhemoglobin values for the plantar metatarsal, arch, and heel angiosomes were significantly different between patients with and without PAD (P Oxyhemoglobin values did not predict the presence or

    Workplace based assessments (WBAs) have been part of UK training for the last 3 years. Carrying out procedures efficiently and safely is of paramount importance in anaesthesia. To explore opinions and experiences of Direct Observation of Procedural Skills (DOPS) assessments in a regional anaesthetic training programme. 19 and 20-item questionnaires were distributed to trainees and consultants respectively. Questionnaire response rate was 76% (90/119) for trainees and 65% (129/199) for consultants. 43% of consultants and 33% of trainees were not trained in DOPS use. Assessments were usually not planned. 50% were ad hoc and the remainder mainly retrospective. Time spent on assessment was short with DOPS and feedback achieved in ≤15 minutes in the majority of cases with lack of suggestions for further improvement. Both trainees and consultants felt that DOPS was not a helpful learning tool (p = 0.001) or a reflection of trainee competency. DOPS assessments are currently not valued as an educational tool. Training is essential in use of this WBA tool which needs to be planned and sufficient time allocated so as to address current negative attitudes.

    Neonatal jaundice is an important disorder, because of its potential complication of kernicterus. Biochemical estimation of bilirubin can be unreliable with lots of interpersonal and interlaboratory variability. Minolta jaundicemeter and perspex icterometer were evaluated for their usefulness in assessment of neonatal jaundice. Thirty premature babies with hyperbilirubinemia were simultaneously studied with jaundicemeter, icterometer and their plasma bilirubin were estimated by AO Bilirubinometer. Babies were subdivided into three groups, viz., Group I upto 1500 g birth weight, Group II 1501-2500 g with gestation 33-34 weeks and Group III 1501-2500 g with gestation 35-36 weeks. There was a good correlation between minolta Jaundicemeter and plasma bilirubin with 'r' values of 0.84, 0.89 and 0.72 in Groups I, II and III, respectively. Except for Group III (r = 0.67), good correlation was found between icterometer and plasma bilirubin with 'r' value of 0.84 and 0.82 in Groups I and II, respectively.

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

    Semen quality in dogs has not been assessed in a longitudinal study that includes endpoints of female fertility and pregnancy. Although use of artificial insemination with chilled semen is increasingly used in canine reproduction, the resultant level of predictability and odds of fertile matings for dogs is still not fully understood. This research provides, for the first time, comprehensive semen evaluation in a large population of dogs in which fertility has been tracked. Duplicate ejaculates were obtained from 39 Labrador retriever males of the Guide Dogs for the Blind (San Rafael, CA, USA) breeding program. Sperm endpoints were determined in fresh semen and extended chilled semen at 48 hour after collection. Evaluation included total and progressive motility, average path velocity, morphology, membrane lipid peroxidation, presence of sperm reactive oxygen species, sperm chromatin structure, and mitochondrial DNA copy number. Male age ranged from 1 to 10 years and were grouped as young (Y; 1-3 years, n = 21), middle aged (M; 4-6 years, n = 13), and senior (S; 7 years or greater, n = 5) for analysis. The effects of age and sperm state (fresh vs. chilled) on the above sperm endpoints were determined using a linear mixed effects model. Semen endpoint values for all parameters were established for this group of fertile males. Progressive motility was only lower in the senior male chilled samples compared to all other groups, fresh and chilled (P dogs compared with the other age groups (P < 0.05). The presence of reactive oxygen species was lower in chilled samples compared with fresh (P < 0.05). For sperm chromatin structure, the senior-aged group had a higher %COMPαt than the middle-aged group (P < 0.05). Bayesian analysis determined that no differences were seen in total motility, membrane lipid peroxidation, and mitochondrial DNA copy number, with regard to conception rate or average litter size between age groups or between fresh and chilled samples

    Haist, Steven A; Butler, Agata P; Paniagua, Miguel A


    The aim of this review is to highlight recent and potential future enhancements to the United States Licensing Examination (USMLE) program. The USMLE program is co-owned by the National Board of Medical Examiners (NBME) and the Federation of State Medical Boards. The USMLE includes four examinations: Step 1, Step 2 Clinical Knowledge, Step 2 Clinical Skills, and Step 3; every graduate of Liaison Committee on Medical Education-accredited allopathic medical schools and all international medical graduates must pass this examination series to practice medicine in the United States. From 2006 to 2009, the program underwent an indepth review resulting in five accepted recommendations. These recommendations have been the primary driver for many of the recent enhancements, such as an increased emphasis on foundational science and changes in the clinical skills examination, including more advanced communication skills assessment. These recommendations will continue to inform future changes such as access to references (e.g., a map of metabolic pathways) or decision-making tools for use during the examination. The NBME also provides assessment services globally to medical schools, students, residency programs, and residents. In 2015, >550,000 assessments were provided through the subject examination program, NBME self-assessment services, and customized assessment services.

Subjects were divided into two groups. In one group Rockport test was used to estimate their VO2 max and in other group Balk test was used for the same purpose. Also, the VO2max of both groups were examined by a standard treadmill test and the results were compared with the results of field tests. The one way of ANOVA and Tukey's post-hoc tests were used for data analysis (p>0/05. The results showed that there were significant differences between the results of the field tests and standard treadmill test (Bruce: 40.93±5.83 vs. Rockport: 58.71±2.73 and Balke: 52.09± 6.18. As a result of these findings it was concluded that the regression equations used in this study used is not suitable for 15-17 (yr boys and does not estimate their aerobic power correctly.

  6. Bottle Traps and Dipnetting: Evaluation of two Sampling Techniques for Assessing Macroinvertebrate Biodiversity in Depressional Wetlands. (United States)

    Serieyssol, C. A.; Bouchard, R. W.; Sealock, A. W.; Rufer, M. M.; Chirhart, J.; Genet, J.; Ferrington, L. C.


    Dipnet (DN) sampling is routinely employed for macroinvertebrate bioassessments, however it has been shown that some taxa are more effectively sampled with activity traps, commonly called Bottle Traps (BT). In 2001, the Minnesota Pollution Control Agency used both DN and BT sampling in nine depressional wetlands in the North Central Hardwood Forest Ecoregion to evaluate macroinvertebrate biodiversity for the purpose of assessing water quality and developing biological criteria. Both methods, consisting of five bottle trap samples and two dip net samples per wetland, were collected from each of two sites in each wetland. To determine the performance of each method in documenting biodiversity, we compared taxa and their abundances by wetland, for each type of sample. DN sampling was more effective, with 44 of 140 macroinvertebrate taxa only identified from DN, compared to 14 only from BT. By contrast, BT more effectively collected leeches and beetles, especially active swimmers such as Tropisternus and several genera of Dytiscidae. However, taxa richness patterns for BT and DN were not strongly correlated. Consequently, we conclude these two sampling methods complement each other, providing a better overall picture of macroinvertebrate biodiversity, and should be used jointly when investigating macroinvertebrate biodiversity in depressional wetlands.

    Full Text Available Introduction: Childhood is the time of onset for many psychiatric disorders. Preschool Age Psychiatric Assessment (PAPA is developed in response to the need for a standard and reliable tool for assessment of psychiatric disorders in preschool age. The aim of this study was to translate this tool to Farsi and evaluate the face and content validity of this precious and comprehensive tool. Methods: The process was forward translation to Farsi, evaluation for face and content validity, finalization of items within expert panel, backward translation to English, matching the original PAPA with randomly selected items from the backward translation version and revision as needed and finally evaluation for validity of the changes for localization and cultural considerations. Results: The research team translated original PAPA to Farsi. In the next step, evaluation for face and content validity was performed by expert panel, a mean of 30-35 items from 100 pages were revised and 7 items which were not compatible with social and cultural conditions in our country got localized. Two percent of pages from this forward translation (14 pages were randomly selected as a sample from the whole questionnaire in order to be back translated to Farsi and expert panel were asked to evaluate. This version was revised based on their comments. The localized items were evaluated based on certainty, necessity and appropriateness and revised if needed. Conclusion: Farsi version of PAPA diagnostic interview for preschool age is available and has face and content validity.

  12. Development and evaluation of a computer-based medical work assessment programme

    Directory of Open Access Journals (Sweden)

    Spallek Michael


    Full Text Available Abstract Background There are several ways to conduct a job task analysis in medical work environments including pencil-paper observations, interviews and questionnaires. However these methods implicate bias problems such as high inter-individual deviations and risks of misjudgement. Computer-based observation helps to reduce these problems. The aim of this paper is to give an overview of the development process of a computer-based job task analysis instrument for real-time observations to quantify the job tasks performed by physicians working in different medical settings. In addition reliability and validity data of this instrument will be demonstrated. Methods This instrument was developed in consequential steps. First, lists comprising tasks performed by physicians in different care settings were classified. Afterwards content validity of task lists was proved. After establishing the final task categories, computer software was programmed and implemented in a mobile personal computer. At least inter-observer reliability was evaluated. Two trained observers recorded simultaneously tasks of the same physician. Results Content validity of the task lists was confirmed by observations and experienced specialists of each medical area. Development process of the job task analysis instrument was completed successfully. Simultaneous records showed adequate interrater reliability. Conclusion Initial results of this analysis supported the validity and reliability of this developed method for assessing physicians' working routines as well as organizational context factors. Based on results using this method, possible improvements for health professionals' work organisation can be identified.

  13. Integrating Assessment and Evaluation Into Partnership Initiatives: Lessons From the Community Partnerships for Older Adults. (United States)

    Giunta, Nancy; Thomas, M Lori


    Communities nationwide have formed cross-sector partnerships to face the needs of an aging population, particularly for the purpose of improving long-term supportive service systems. Research is limited on how evaluation strategies are incorporated into partnership work, especially in the field of aging. This retrospective qualitative study reviewed administrative and key informant interview data to examine how 15 community partnerships (CPs) within the Community Partnerships for Older Adults (CPFOA) national program incorporated evaluation into their work. The four overarching lessons drawn from our inquiry suggest that effective CPs: (a) incorporate both formative and summative methods into evaluation, (b) use and develop the knowledge and skills of its members, (c) support flexible and creative evaluation methods and strategies, and (d) use internal and external resources to support evaluation efforts, particularly with nontraditional partners. There is a need for continued research to capture the methodological complexity of partnership evaluation. © The Author(s) 2013.

  14. Assessment of Risk Evaluation and Mitigation Strategies in Oncology: Summary of the Oncology Risk Evaluation and Mitigation Strategies Workshop (United States)

    Frame, James N.; Jacobson, Joseph O.; Vogel, Wendy H.; Griffith, Niesha; Wariabharaj, Darshan; Garg, Rekha; Zon, Robin; Stephens, Cyntha L.; Bialecki, Alison M.; Bruinooge, Suanna S.; Allen, Steven L.


    To address oncology community stakeholder concerns regarding implementation of the Risk Evaluation and Mitigation Strategies (REMS) program, ASCO sponsored a workshop to gather REMS experiences from representatives of professional societies, patient organizations, pharmaceutical companies, and the US Food and Drug Administration (FDA). Stakeholder presentations and topical panel discussions addressed REMS program development, implementation processes, and practice experiences, as well as oncology drug safety processes. A draft REMS decision tool prepared by the ASCO REMS Steering Committee was presented for group discussion with facilitated, goal-oriented feedback. The workshop identified several unintended consequences resulting from current oncology REMS: (1) the release of personal health information to drug sponsors as a condition for gaining access to a needed drug; (2) risk information that is not tailored—and therefore not accessible—to all literacy levels; (3) exclusive focus on drug risk, thereby affecting patient-provider treatment discussion; (4) REMS elements that do not consider existing, widely practiced oncology safety standards, professional training, and experience; and (5) administrative burdens that divert the health care team from direct patient care activities and, in some cases, could limit patient access to important therapies. Increased provider and professional society participation should form the basis of ongoing and future REMS standardization discussions with the FDA to work toward overall improvement of risk communication.

  15. Environmental management: integrating ecological evaluation, remediation, restoration, natural resource damage assessment and long-term stewardship on contaminated lands. (United States)

    Burger, Joanna


    Ecological evaluation is essential for remediation, restoration, and Natural Resource Damage Assessment (NRDA), and forms the basis for many management practices. These include determining status and trends of biological, physical, or chemical/radiological conditions, conducting environmental impact assessments, performing remedial actions should remediation fail, managing ecosystems and wildlife, and assessing the efficacy of remediation, restoration, and long-term stewardship. The objective of this paper is to explore the meanings of these assessments, examine the relationships among them, and suggest methods of integration that will move environmental management forward. While remediation, restoration, and NRDA, among others, are often conducted separately, it is important to integrate them for contaminated land where the risks to ecoreceptors (including humans) can be high, and the potential damage to functioning ecosystems great. Ecological evaluations can range from inventories of local plants and animals, determinations of reproductive success of particular species, levels of contaminants in organisms, kinds and levels of effects, and environmental impact assessments, to very formal ecological risk assessments for a chemical or other stressor. Such evaluations can range from the individual species to populations, communities, ecosystems or the landscape scale. Ecological evaluations serve as the basis for making decisions about the levels and kinds of remediation, the levels and kinds of restoration possible, and the degree and kinds of natural resource injuries that have occurred because of contamination. Many different disciplines are involved in ecological evaluation, including biologists, conservationists, foresters, restoration ecologists, ecological engineers, economists, hydrologist, and geologists. Since ecological evaluation forms the basis for so many different types of environmental management, it seems reasonable to integrate management options

    An update of a Dutch physiotherapy practice guideline in Hip and Knee Osteoarthritis (HKOA) was made, based on current evidence and best practice. A guideline steering committee, comprising 10 expert physiotherapists, selected topics concerning the guideline chapters: initial assessment, treatment and evaluation. With respect to treatment a systematic literature search was performed using various databases, and the evidence was graded (1-4). For the initial assessment and evaluation mainly review papers and textbooks were used. Based on evidence and expert opinion, recommendations were formulated. A first draft of the guideline was reviewed by 17 experts from different professional backgrounds. A second draft was field-tested by 45 physiotherapists. In total 11 topics were selected. For the initial assessment, three recommendations were formulated, pertaining to history taking, red flags, and formulating treatment goals. Concerning treatment, 7 recommendations were formulated; (supervised) exercise therapy, education and self management interventions, a combination of exercise and manual therapy, postoperative exercise therapy and taping of the patella were recommended. Balneotherapy and hydrotherapy in HKOA, and thermotherapy, TENS, and Continuous Passive Motion in knee OA were neither recommended nor discouraged. Massage therapy, ultrasound, electrotherapy, electromagnetic field, Low Level Laser Therapy, preoperative physiotherapy and education could not be recommended. For the evaluation of treatment goals the following measurement instruments were recommended: Lequesne index, Western Ontario and McMaster Universities osteoarthritis index, Hip disability and Osteoarthritis Outcome Score and Knee injury and Osteoarthritis Outcome Score, 6-minute walktest, Timed Up and Go test, Patient Specific Complaint list, Visual Analoge Scale for pain, Intermittent and Constant OsteoArthritis Pain Questionnaire, goniometry, Medical Research Council for strength, handheld

  17. HEPATIC STEATOSIS ASSESSMENT: a comparative study between surgeon evaluation and forward histopathologic findings

    Directory of Open Access Journals (Sweden)

    Aline M. A. MARTINS


    Full Text Available Context Liver transplantation is one of the last viable resources for patients with end-stage liver disease. Many strategies are been used to improve the number of available organs and overcome waiting list delay. However, hepatic steatosis is one of the mainly concerns when organs are consider to transplantation due to it is importance as a risk factor for primary dysfunction. Surgeons play an important role to decide each organ will be accept or decline and its righteous allocation. Objective Retrospectively evaluate the surgeon assessment of steatosis degree and its confrontation with further histopathologic findings. Methods We analyzed 117 patients underwent deceased liver transplantation for end-stage liver disease in University Hospital Walter Cantideo, Fortaleza, CE, Brazil. A matrix table was organized to estimate the categorical data observed. We clustered the subjects into mild (0%–30% and moderate (30%-60% steatosis degree under the clinical criteria of organ suitability for transplantation. We categorized the organs as suitable organ for transplant and as non-suitable organ for transplant. Evaluations between the two first assessments, before perfusion (pre-perfusion vs biopsy findings and after perfusion vs biopsy findings observations were analyzed and also a comparison between pre-perfusion and after perfusion data was performed. Results On the first assessment, we obtained a 93% of agreement (n = 109 between the two evaluations. On the second assessment, we had an 8% (n = 9 of mistaken allocation. Comparing the observation before (pre-perfusion and after (after perfusion, we obtained a strong agreement between the surgeons. Conclusions Although our experienced surgeon team, we have wrongly evaluated feasible organs for transplantation. Nonetheless, our faulty percentage is low comparing to worldwide percentage.

  19. Environmental evaluation of transfer and treatment of excess pig slurry by life cycle assessment. (United States)

    Lopez-Ridaura, Santiago; Werf, Hayo van der; Paillat, Jean Marie; Le Bris, Bertrand


    Slurry management is a central topic in the agronomic and environmental analysis of intensive livestock production systems. The objective of this study is to compare the environmental performance of two scenarios of collective slurry management for the disposal of excess nitrogen from animal manure. The scenarios are the transfer of slurry and its injection to crop land, and the treatment of slurry in a collective biological treatment station. The study is based on a real case in the West of France, where a group of farmers is developing a collective plan for the disposal of almost 7000 m(3) of excess pig slurry. The evaluation is carried out by Life Cycle Assessment, where emissions and resource consumption are quantified and aggregated into four environmental impact categories: eutrophication, acidification, climate change, and non-renewable energy use. Ammonia emitted is the most important contributor to acidification and eutrophication, while methane contributes most to climate change. Both ammonia and methane are mostly emitted during the storage of slurry and, in the case of the treatment scenario, also during composting the solid fraction of the slurry. The two management strategies are similar with respect to climate change, whereas eutrophication and acidification are twice as large for treatment relative to transfer. Electricity needed for the treatment process is the main contributor to non-renewable energy use for the treatment scenario, while the transfer scenario represents a net energy saving, as energy saved by the reduction of mineral fertiliser use more than compensates for the energy needed for transport and injection of slurry. The overall environmental performance of transfer is better than that of treatment, as it involves less acidification, eutrophication and non-renewable energy use. The method employed and the results obtained in this study can provide elements for a transparent discussion of the advantages and disadvantages of contrasting

  6. Evaluation and selection of decision-making methods to assess landfill mining projects. (United States)

    Hermann, Robert; Baumgartner, Rupert J; Vorbach, Stefan; Ragossnig, Arne; Pomberger, Roland


    For the first time in Austria, fundamental technological and economic studies on recovering secondary raw materials from large landfills have been carried out, based on the 'LAMIS - Landfill Mining Austria' pilot project. A main focus of the research - and the subject of this article - was to develop an assessment or decision-making procedure that allows landfill owners to thoroughly examine the feasibility of a landfill mining project in advance. Currently there are no standard procedures that would sufficiently cover all the multiple-criteria requirements. The basic structure of the multiple attribute decision making process was used to narrow down on selection, conceptual design and assessment of suitable procedures. Along with a breakdown into preliminary and main assessment, the entire foundation required was created, such as definitions of requirements to an assessment method, selection and accurate description of the various assessment criteria and classification of the target system for the present 'landfill mining' vs. 'retaining the landfill in after-care' decision-making problem. Based on these studies, cost-utility analysis and the analytical-hierarchy process were selected from the range of multiple attribute decision-making procedures and examined in detail. Overall, both methods have their pros and cons with regard to their use for assessing landfill mining projects. Merging these methods or connecting them with single-criteria decision-making methods (like the net present value method) may turn out to be reasonable and constitute an appropriate assessment method. © The Author(s) 2015.

    Conclusion: Health Impact Assessment (HIA has been required for large development projects by the fifth development plan, however, there is a need to HIA by another fields such as air pollution and urban subjects as they have effects on human health. Presenting such assessment before presentation national health standards requirement of Iran indicates this fact. Thus, we expect from politicians and decision makers to address these issues and apply HIA by other fields alongside assessment of national development projects and plans. By doing so, we can bridge the gap between knowledge and action which may result in health promotion in the society.

  11. Telemetric assessment of social and single housing: Evaluation of electrocardiographic intervals in jacketed cynomolgus monkeys. (United States)

    Kaiser, Robert A; Tichenor, Stephen D; Regalia, Douglas E; York, Kristina; Holzgrefe, Henry H


    Proactive efforts to socially house laboratory animals are a contemporary, important focus for enhancing animal welfare. Jacketing cynomolgus monkeys has been traditionally considered an exclusionary criterion for social housing based on unsubstantiated concerns that study conduct or telemetry equipment might be compromised. Our objective was to evaluate the effects of jacketing naïve, adolescent cynomolgus monkeys in different single and social housing types based on parallel comparisons of heart rate. Eight naive cynomolgus monkeys were randomized into pairs and ECG data were collected for 24h from each animal in each housing condition using a crossover design. Caging paradigms consisted of standard individual, standard pair, quaternary pair (4 linked cages), and European-style pair housing in non-sequential order varied by pair to control for possible time bias. Dosing and blood collection procedures were performed to characterize any effects of housing on ECG data during study conduct. There was no increase in the incidence of equipment damage in pair vs. individually housed animals. Further, animals in all 4 housing paradigms showed similar acclimation assessed as heart rate (mean 139-154 beats per minute), and maintained similar diurnal rhythms, with an expected slowing of the heart rate at night (aggregate lights out HR 110±4bpm compared to daytime 146±7bpm). This study demonstrates the effects of different social access and housing types on the study-naïve cynomolgus monkeys during jacketed cardiovascular telemetry data collection in a repeat-dose toxicology study design. There were no discernible effects of social housing on baseline ECG parameters collected via jacketed telemetry, and all animals maintained expected diurnal rhythms in all housing settings tested. These data demonstrate that cynomolgus monkeys can be socially housed during data collection as a standard practice, consistent with global efforts to improve study animal welfare. Copyright

  12. Evaluation and review of body fluids saliva, sweat and tear compared to biochemical hydration assessment markers within blood and urine. (United States)

    Villiger, M; Stoop, R; Vetsch, T; Hohenauer, E; Pini, M; Clarys, P; Pereira, F; Clijsen, R


    Evaluating and testing hydration status is increasingly requested by rehabilitation, sport, military and performance-related activities. Besides commonly used biochemical hydration assessment markers within blood and urine, which have their advantages and limitations in collection and evaluating hydration status, there are other potential markers present within saliva, sweat or tear. This literature review focuses on body fluids saliva, sweat and tear compared to blood and urine regarding practicality and hydration status influenced by fluid restriction and/or physical activity. The selected articles included healthy subjects, biochemical hydration assessment markers and a well-described (de)hydration procedure. The included studies (n=16) revealed that the setting and the method of collecting respectively accessing body fluids are particularly important aspects to choose the optimal hydration marker. To obtain a sample of saliva is one of the simplest ways to collect body fluids. During exercise and heat exposures, saliva composition might be an effective index but seems to be highly variable. The collection of sweat is a more extensive and time-consuming technique making it more difficult to evaluate dehydration and to make a statement about the hydration status at a particular time. The collection procedure of tear fluid is easy to access and causes very little discomfort to the subject. Tear osmolarity increases with dehydration in parallel to alterations in plasma osmolality and urine-specific gravity. But at the individual level, its sensitivity has to be further determined.

  13. The Costs of Evaluating Species Densities and Composition of Snakes to Assess Development Impacts in Amazonia (United States)

    de Fraga, Rafael; Stow, Adam J.; Magnusson, William E.; Lima, Albertina P.


    Studies leading to decision-making for environmental licensing often fail to provide accurate estimates of diversity. Measures of snake diversity are regularly obtained to assess development impacts in the rainforests of the Amazon Basin, but this taxonomic group may be subject to poor detection probabilities. Recently, the Brazilian government tried to standardize sampling designs by the implementation of a system (RAPELD) to quantify biological diversity using spatially-standardized sampling units. Consistency in sampling design allows the detection probabilities to be compared among taxa, and sampling effort and associated cost to be evaluated. The cost effectiveness of detecting snakes has received no attention in Amazonia. Here we tested the effects of reducing sampling effort on estimates of species densities and assemblage composition. We identified snakes in seven plot systems, each standardised with 14 plots. The 250 m long centre line of each plot followed an altitudinal contour. Surveys were repeated four times in each plot and detection probabilities were estimated for the 41 species encountered. Reducing the number of observations, or the size of the sampling modules, caused significant loss of information on species densities and local patterns of variation in assemblage composition. We estimated the cost to find a snake as $ 120 U.S., but general linear models indicated the possibility of identifying differences in assemblage composition for half the overall survey costs. Decisions to reduce sampling effort depend on the importance of lost information to target-issues, and may not be the preferred option if there is the potential for identifying individual snake species requiring specific conservation actions. However, in most studies of human disturbance on species assemblages, it is likely to be more cost-effective to focus on other groups of organisms with higher detection probabilities. PMID:25147930

  14. Environmental assessment for the satellite power system concept development and evaluation program: nonmicrowave health and ecological effects

    Energy Technology Data Exchange (ETDEWEB)

    White, M R


    A Concept Development and Evaluation Program is being carried out for a proposed Satellite Power System (SPS). For purposes of this evaluation, a preliminary reference system has been developed. SPS, as described in the reference system, would collect solar energy on satellites in geosychronous orbit in space. The energy would be converted to microwaves and beamed to an earth-receiving antenna (rectenna). One task in the environmental part of the program is the assessment of the nonmicrowave effects on health and the environment. These effects would result from all phases of SPS development and operation. This report covers the current knowledge regarding these effects, and is based on the reference system. The assessment is summarized as to scope, methodology, impacts of terrestrial development, launch and recovery of spacecraft, space activities (including health effects of the space environment, ionizing radiation, electromagnetic exposure, spacecraft charging and environmental interactions, occupational hazards, etc.) and construction and operation of rectenna (ground receiving station).

  16. Inter-laboratory evaluation of instrument platforms and experimental workflows for quantitative accuracy and reproducibility assessment

    Directory of Open Access Journals (Sweden)

    Andrew J. Percy


    Full Text Available The reproducibility of plasma protein quantitation between laboratories and between instrument types was examined in a large-scale international study involving 16 laboratories and 19 LC–MS/MS platforms, using two kits designed to evaluate instrument performance and one kit designed to evaluate the entire bottom-up workflow. There was little effect of instrument type on the quality of the results, demonstrating the robustness of LC/MRM-MS with isotopically labeled standards. Technician skill was a factor, as errors in sample preparation and sub-optimal LC–MS performance were evident. This highlights the importance of proper training and routine quality control before quantitation is done on patient samples.

  18. Using In-Training Evaluation Report (ITER) Qualitative Comments to Assess Medical Students and Residents: A Systematic Review. (United States)

    Hatala, Rose; Sawatsky, Adam P; Dudek, Nancy; Ginsburg, Shiphra; Cook, David A


    In-training evaluation reports (ITERs) constitute an integral component of medical student and postgraduate physician trainee (resident) assessment. ITER narrative comments have received less attention than the numeric scores. The authors sought both to determine what validity evidence informs the use of narrative comments from ITERs for assessing medical students and residents and to identify evidence gaps. Reviewers searched for relevant English-language studies in MEDLINE, EMBASE, Scopus, and ERIC (last search June 5, 2015), and in reference lists and author files. They included all original studies that evaluated ITERs for qualitative assessment of medical students and residents. Working in duplicate, they selected articles for inclusion, evaluated quality, and abstracted information on validity evidence using Kane's framework (inferences of scoring, generalization, extrapolation, and implications). Of 777 potential articles, 22 met inclusion criteria. The scoring inference is supported by studies showing that rich narratives are possible, that changing the prompt can stimulate more robust narratives, and that comments vary by context. Generalization is supported by studies showing that narratives reach thematic saturation and that analysts make consistent judgments. Extrapolation is supported by favorable relationships between ITER narratives and numeric scores from ITERs and non-ITER performance measures, and by studies confirming that narratives reflect constructs deemed important in clinical work. Evidence supporting implications is scant. The use of ITER narratives for trainee assessment is generally supported, except that evidence is lacking for implications and decisions. Future research should seek to confirm implicit assumptions and evaluate the impact of decisions.

  20. Evaluation of orthodontists' perception of treatment need and the peer assessment rating (PAR) index. (United States)

    McGorray, S P; Wheeler, T T; Keeling, S D; Yurkiewicz, L; Taylor, M G; King, G J


    This paper examines the relationship between orthodontists' subjective assessment of treatment need and objective measurements obtained during standardized intra- and extraoral examinations. Logistic regression modeling was used to develop predictive models of treatment need. Data were obtained from 1155 eighth-grade students by four orthodontists who used standardized examination forms to assess demographics, trauma, skeletal relationships, morphologic malocclusion traits, and mandibular function. At the conclusion of the examination, the orthodontist rated the subjective treatment need as none, elective, recommended, soon, or immediate. For some analyses, the categories were collapsed to represent no need and need. The peer assessment rating (PAR) index (American validated version) was computed from the clinical exam findings and scoring of dental models; PAR scores were used to document malocclusion severity and treatment difficulty. Spearman rank correlation coefficients quantified the relationship between PAR scores and need categories. Logistic regression analysis modeled treatment need using components of the PAR index as well as other variables. The components of these models, as well as sensitivity and specificity, were compared with malocclusion severity/treatment difficulty scores obtained from malocclusion assessments using the PAR index. The five subjective treatment need categories and the PAR index scores were significantly correlated (rho = 0.62, porthodontists' subjective assessment of treatment need when that assessment is made in the absence of financial considerations and patient desires.

  1. Implementation and evaluation of a pre-assessment telephone triage system in an outpatient photopheresis service. (United States)

    Rushton, Cherie; Robertson, Leeah; Taylor, Tracie; Taylor, Peter; Alfred, Arun


    The prompt assessment of patients as fit for photopheresis is imperative to ensure delivery of a safe and efficient service. Before January 2015 the photopheresis unit was reliant on patients contacting the department directly to cancel their appointment if they were unwell or were suffering from any pre-defined exclusion criteria. Methods to reduce the number of cancellations and patients arriving unwell were therefore examined. The authors combined aspects of patient pre-assessment with telephone triage to develop a system that could provide better care and improve the use of resources within the department. The pre-assessment telephone triage system successfully reduced cancellations and increased patient awareness of conditions that would prevent delivery of photopheresis treatment. Subsequently the quality improvement initiative established that the pre-assessment telephone triage system saved the photopheresis unit over £33 000 over a 12-month period.

    Huang, Mei-Jen; Chen, Shao-Der; Chao, Yu-Jui; Chiang, Yi-Lin; Chang, Kuo-Jen


    Taiwan, due to the high seismicity and high annual rainfall, numerous landslides triggered every year and severe impacts affect the island. Concerning to the catastrophic landslides, the key information of landslide, including range of landslide, volume estimation and the subsequent evolution are important when analyzing the triggering mechanism, hazard assessment and mitigation. Thus, the morphological analysis gives a general overview for the landslides and been considered as one of the most fundamental information. We try to integrate several technologies, especially by Unmanned Aerial Vehicle (UAV) and multi-spectral camera, to decipher the consequence and the potential hazard, and the social impact. In recent years, the remote sensing technology improves rapidly, providing a wide range of image, essential and precious information. Benefited of the advancing of informatics, remote-sensing and electric technologies, the Unmanned Aerial Vehicle (UAV) photogrammetry mas been improve significantly. The study tries to integrate several methods, including, 1) Remote-sensing images gathered by Unmanned Aerial Vehicle (UAV) and by aerial photos taken in different periods; 2) field in-situ geologic investigation; 3) Differential GPS, RTK GPS and Ground LiDAR field in-site geoinfomatics measurements; 4) Construct the DTMs before and after landslide, as well as the subsequent periods using UAV and aerial photos; 5) Discrete element method should be applied to understand the geomaterial composing the slope failure, for predicting earthquake-induced and rainfall-induced landslides displacement. First at all, we evaluate the Microdrones MD4-1000 UAV airphotos derived Digital Terrain Model (DTM). The ground resolution of the DSM point cloud of could be as high as 10 cm. By integrated 4 ground control point within an area of 56 hectares, compared with LiDAR DSM and filed RTK-GPS surveying, the mean error is as low as 6cm with a standard deviation of 17cm.

    Neurobehavioral tests have long been used to assess health effects in exposed working adult populations. The heightened concern over the potential impact of environmental exposures on neurological functioning in children has led to the development of test batteries for use with children. There is a need for reliable, easy-to-administer batteries to assess neurotoxic exposure in children. One such test battery previously validated with Spanish- and English-speaking children ages 4 and older, c...

  4. Preclinical evaluation of nuclear morphometry and tissue topology for breast carcinoma detection and margin assessment. (United States)

    Nyirenda, Ndeke; Farkas, Daniel L; Ramanujan, V Krishnan


    Prevention and early detection of breast cancer are the major prophylactic measures taken to reduce the breast cancer related mortality and morbidity. Clinical management of breast cancer largely relies on the efficacy of the breast-conserving surgeries and the subsequent radiation therapy. A key problem that limits the success of these surgeries is the lack of accurate, real-time knowledge about the positive tumor margins in the surgically excised tumors in the operating room. This leads to tumor recurrence and, hence, the need for repeated surgeries. Current intraoperative techniques such as frozen section pathology or touch imprint cytology severely suffer from poor sampling and non-optimal detection sensitivity. Even though histopathology analysis can provide information on positive tumor margins post-operatively (~2-3 days), this information is of no immediate utility in the operating rooms. In this article, we propose a novel image analysis method for tumor margin assessment based on nuclear morphometry and tissue topology and demonstrate its high sensitivity/specificity in preclinical animal model of breast carcinoma. The method relies on imaging nuclear-specific fluorescence in the excised surgical specimen and on extracting nuclear morphometric parameters (size, number, and area fraction) from the spatial distribution of the observed fluorescence in the tissue. We also report the utility of tissue topology in tumor margin assessment by measuring the fractal dimension in the same set of images. By a systematic analysis of multiple breast tissues specimens, we show here that the proposed method is not only accurate (~97% sensitivity and 96% specificity) in thin sections, but also in three-dimensional (3D) thick tissues that mimic the realistic lumpectomy specimens. Our data clearly precludes the utility of nuclear size as a reliable diagnostic criterion for tumor margin assessment. On the other hand, nuclear area fraction addresses this issue very

  5. Development and psychometric evaluation of a cardiovascular risk and disease management knowledge assessment tool. (United States)

    Rosneck, James S; Hughes, Joel; Gunstad, John; Josephson, Richard; Noe, Donald A; Waechter, Donna


    This article describes the systematic construction and psychometric analysis of a knowledge assessment instrument for phase II cardiac rehabilitation (CR) patients measuring risk modification disease management knowledge and behavioral outcomes derived from national standards relevant to secondary prevention and management of cardiovascular disease. First, using adult curriculum based on disease-specific learning outcomes and competencies, a systematic test item development process was completed by clinical staff. Second, a panel of educational and clinical experts used an iterative process to identify test content domain and arrive at consensus in selecting items meeting criteria. Third, the resulting 31-question instrument, the Cardiac Knowledge Assessment Tool (CKAT), was piloted in CR patients to ensure use of application. Validity and reliability analyses were performed on 3638 adults before test administrations with additional focused analyses on 1999 individuals completing both pretreatment and posttreatment administrations within 6 months. Evidence of CKAT content validity was substantiated, with 85% agreement among content experts. Evidence of construct validity was demonstrated via factor analysis identifying key underlying factors. Estimates of internal consistency, for example, Cronbach's α = .852 and Spearman-Brown split-half reliability = 0.817 on pretesting, support test reliability. Item analysis, using point biserial correlation, measured relationships between performance on single items and total score (P knowledge instrument specifically designed for an adult CR population was systematically developed and tested in a large representative patient population, satisfying psychometric parameters, including validity and reliability.

    Kitch, D.M.; Schlonski, J.S.; Sowatskey, P.J.; Cesarski, W.V.


    This report was produced under the Detection of Defects and Degradation Monitoring Element of the Nuclear Plant Aging Research Program. It addresses aging assessments and monitoring method evaluations for auxiliary feedwater pumps (AUXFPs). The report contains four major sections: failure causes; review of inspection, surveillance, and condition monitoring (ISCM) methods; evaluation of ISCM methods; and role of maintenance in alleviating aging and service wear. Failure causes attributable to aging and service wear are given and ranked in terms of importance. Cause identifications are made on the bases of experience, postservice examinations, and in situ assessments. Measurable parameters related to failure causes are identified. ISCM methods are also identified, evaluations are made based on Westinghouse (W) experience, and recommendations are given. The methods are intended to yield required capabilities for establishing operational readiness, as well as for detecting and tracking degradation. The role of maintenance in mitigating aging and service wear effects is discussed, and the relationship of maintenance to ISCM methods is identified. Predictive, preventive, and corrective maintenance practices are discussed and evaluated.

    Deregulation and open access in the natural gas pipeline industry has changed the gas business environment towards greater reliance on local energy flow rate measurement. What was once a large, stable, and well-defined source of natural gas is now a composite from many small suppliers with greatly varying gas compositions. Unfortunately, the traditional approach to energy flow measurement [using a gas chromatograph (GC) for composition assay in conjunction with a flow meter] is only cost effective for large capacity supplies (typically greater than 1 to 30 million scfd). A less costly approach will encourage more widespread use of energy measurement technology. In turn, the US will benefit from tighter gas inventory control, more efficient pipeline and industrial plant operations, and ultimately lower costs to the consumer. An assessment of the state and direction of technology for natural gas energy flow rate measurement is presented. The alternative technologies were ranked according to their potential to dramatically reduce capital and operating and maintenance (O and M) costs, while improving reliability and accuracy. The top-ranked technologies take an unconventional inference approach to the energy measurement problem. Because of that approach, they will not satisfy the fundamental need for composition assay, but have great potential to reduce industry reliance on the GC. Technological feasibility of the inference approach was demonstrated through the successful development of data correlations that relate energy measurement properties (molecular weight, mass-based heating value, standard density, molar ideal gross heating value, standard volumetric heating value, density, and volume-based heating value) to three inferential properties: standard sound speed, carbon dioxide concentration, and nitrogen concentration (temperature and pressure are also required for the last two). The key advantage of this approach is that inexpensive on-line sensors may be used

  8. Emergy Evaluations of Denmark and Danish Agriculture. Assessing the Limits of Agricultural Systems to Power Society

    Energy Technology Data Exchange (ETDEWEB)

    Haden, Andrew C. [Swedish Univ. of Agricultural Sciences, Uppsala (Sweden). Dept. of Rural Development Studies


    As the process of industrialization has run its course over the twentieth century, the relative importance of agriculture as an economic activity and a means of cultural sustenance for nations has declined dramatically. In this thesis, a historical ecological-economic perspective offers insights into both the causes and effects of Danish agriculture's decline in economic importance relative to the economy of Denmark as a whole. Emergy evaluations were made of the national economy and agricultural subsystem of Denmark for the years 1936, 1970 and 1999. Emergy is defined as all the available energy that was used in the work of making a product and expressed in units of one type of energy. In total, six separate emergy analyses were performed. By quantifying the emergy requirements of both a national agricultural system and the economy within which this system is nested, the analysis highlights the changing relationship of these two systems over a temporal scale of 63 years. The ecological sustainability of the studied systems is assessed through the calculation of emergy-based indices and ratios. In accordance with emergy theory, ecological sustainability is considered to be a function of the dependence of a system on renewable emergy, the degree to which the system depends on imported emergy, and the overall load that the system places on the environment. The analysis indicates that as the national economy of Denmark evolved to rely more on the use of nonrenewable emergy and on emergy appropriated through trade to stimulate economic activity and to generate wealth, its sustainability declined, and the importance of the Danish agricultural system to the national economy subsided. While the total amount of emergy supporting the economy of Denmark over the period studied increased substantially, the total emergy supporting agriculture remained relatively constant. Furthermore, though the emergy signature and thermodynamic efficiencies of Danish agricultural

  9. Assessment of Intralaminar Progressive Damage and Failure Analysis Using an Efficient Evaluation Framework (United States)

    Hyder, Imran; Schaefer, Joseph; Justusson, Brian; Wanthal, Steve; Leone, Frank; Rose, Cheryl


    Reducing the timeline for development and certification for composite structures has been a long standing objective of the aerospace industry. This timeline can be further exacerbated when attempting to integrate new fiber-reinforced composite materials due to the large number of testing required at every level of design. computational progressive damage and failure analysis (PDFA) attempts to mitigate this effect; however, new PDFA methods have been slow to be adopted in industry since material model evaluation techniques have not been fully defined. This study presents an efficient evaluation framework which uses a piecewise verification and validation (V&V) approach for PDFA methods. Specifically, the framework is applied to evaluate PDFA research codes within the context of intralaminar damage. Methods are incrementally taken through various V&V exercises specifically tailored to study PDFA intralaminar damage modeling capability. Finally, methods are evaluated against a defined set of success criteria to highlight successes and limitations.

    David E Murray


    Full Text Available Aim/Purpose: The aim of this project was to explore student perceptions of the value of both the creation of video content and exposure to other students’ work though peer assessment and inclusion of exemplars as unit material. Background: The research was in a first year information technology flipped-learning unit, where the assessment involved students developing video presentations that were peer assessed and exemplars incorporated into the unit as teaching material. Methodology: Data was gathered using a mixed methods approach using an online questionnaire followed by semi-structured interviews with a selection of questionnaire respondents. The interviews were designed to further explore issues identified from the analysis of the questionnaire data. Contribution: Informs on student perceptions of peer review and the integration of student generated content into University teaching. Findings: Most students enjoyed the video assessment (58% with many preferring it to a written or programming task (55-58%. In the subsequent peer assessment, many liked seeing the work of others (67% and found the approach engaging (63% yet some other perceptions were mixed or neutral. Recommendations for Practitioners: University IT students generally enjoyed and perceived peer assessment and found student generated content to be valuable. Recommendation for Researchers: Further investigation of peer review and student generated content in contexts where the student cohort represents a variety of cultures and age categories Impact on Society: Contributes to a body of knowledge regarding peer assessment and student generated educational materials. Future Research: Future work is needed to better understand this domain, in particular the role of learners’ individual differences in order to successfully integrate these approaches into modern learning environments.

  14. Development and Evaluation of a Computer-Based Learning Environment for Teachers: Assessment of Learning Strategies in Learning Journals

    Directory of Open Access Journals (Sweden)

    Inga Glogger


    Full Text Available Training teachers to assess important components of self-regulated learning such as learning strategies is an important, yet somewhat neglected, aspect of the integration of self-regulated learning at school. Learning journals can be used to assess learning strategies in line with cyclical process models of self-regulated learning, allowing for rich formative feedback. Against this background, we developed a computer-based learning environment (CBLE that trains teachers to assess learning strategies with learning journals. The contents of the CBLE and its instructional design were derived from theory. The CBLE was further shaped by research in a design-based manner. Finally, in two evaluation studies, student teachers (N1=44; N2=89 worked with the CBLE. We analyzed satisfaction, interest, usability, and assessment skills. Additionally, in evaluation study 2, effects of an experimental variation on motivation and assessment skills were tested. We found high satisfaction, interest, and good usability, as well as satisfying assessment skills, after working with the CBLE. Results show that teachers can be trained to assess learning strategies in learning journals. The developed CBLE offers new perspectives on how to support teachers in fostering learning strategies as central component of effective self-regulated learning at school.

  17. Convergent, incremental, and criterion-related validity of multi-informant assessments of adolescents' fears of negative and positive evaluation. (United States)

    Karp, Jeremy N; Makol, Bridget A; Keeley, Lauren M; Qasmieh, Noor; Deros, Danielle E; Weeks, Justin W; Racz, Sarah J; Lipton, Melanie F; Augenstein, Tara M; De Los Reyes, Andres


    Adolescents who experience social anxiety tend to hold fears about negative evaluations (e.g., taunting) and may also hold fears about positive evaluations (e.g., praise from a teacher). The Brief Fear of Negative Evaluation (BFNE) scale and Fear of Positive Evaluation Scale (FPES) are 2 widely used measures of adults' evaluative concerns. Yet we know little about their psychometric properties when assessing adolescents. In a mixed clinical/community sample of 96 adolescents (66.7% female; M = 14.50 years, SD = 0.50; 63.3% African American), we examined both self-report and parent report versions of the BFNE and FPES. Adolescents and parents also provided reports about adolescents on survey measures of social anxiety and depressive symptoms. Adolescents participated in multiple social interactions in which they self-reported their state arousal before and during the tasks. Adolescent and parent BFNE and FPES reports distinguished adolescents who displayed elevated social anxiety from those who did not. Both informants' reports related to survey measures of adolescent social anxiety, when accounting for domains that commonly co-occur with social anxiety (i.e., depressive symptoms). Further, both the BFNE and FPES displayed incremental validity in relation to survey measures of adolescent social anxiety, relative to each other. However, only adolescents' BFNE and FPES reports predicted adolescents' self-reported arousal within social interactions, and only adolescents' FPES displayed incremental validity in predicting self-reported arousal, relative to their BFNE. Adolescent and parent BFNE and FPES reports display convergent validity and in some cases incremental and criterion-related validity. These findings have important implications for evidence-based assessments of adolescents' evaluative concerns. Copyright © 2017 John Wiley & Sons, Ltd.

  18. Exposure assessment of four pharmaceutical powders based on dustiness and evaluation of damaged HEPA filters. (United States)

    Levin, Marcus; Koponen, Ismo K; Jensen, Keld A


    In this study, we show the different dustiness characteristics of four molecular pharmaceutical powder candidates and evaluate the performance of HEPA filters damaged with three different pinhole sizes and exposed to dust using real industrial powders in a miniaturized EN15051 rotating drum dustiness tester. We then demonstrate the potential use of such data using first-order exposure modeling to assess the potential worker exposure and transmission of active powder ingredients into ventilation systems. The four powders had highly variable inhalable dustiness indices (1,036 - 14,501 mg/kg). Dust particle size-distributions were characterized by three peaks; the first occurred around 60-80 nm, the second around 250 nm, and the third at 2-3 μm. The second and third peaks are often observed in dustiness test studies, but peaks in the 60-80 nm range have not been previously reported. Exposure modeling in a 5 times 20 kg powder pouring scenario, suggests that excessive dust concentrations may be reached during use of powders with the highest dustiness levels. By number, filter-damage by three pinhole sizes resulted in damage-dependent penetration of 70-80 nm-size particles, but by volume and mass the penetration is still dominated by particles larger than 100 nm. Whereas the exposure potential was evident, the potential dust concentrations in air ducts following the pouring scenario above were at pg/m(3) levels. Hence, filter penetration at these damage levels was assumed to be only critical, if the active ingredients were associated with high hazard or unique product purity is required.

  19. Assessment of the scope and practice of evaluation among medical donation programs. (United States)

    Jenny, Alisa M; Li, Meng; Ashbourne, Elizabeth; Aldrink, Myron; Funk, Christine; Stergachis, Andy


    Medical donation programs for drugs, other medical products, training and other supportive services can improve access to essential medicines in low- and middle-income countries (LMICs) and provide emergency and disaster relief. The scope and extent to which medical donation programs evaluate their impact on recipients and health systems is not well documented. We conducted a survey of the member organizations of the Partnership for Quality Medical Donations (PQMD), a global alliance of non-profit and corporate organizations, to identify evaluations conducted in conjunction with donation programs. Twenty-five out of the 36 PQMD organizations that were members at the time of the survey participated in the study, for a response rate of 69 %. PQMD members provided information on 34 of their major medical donation programs. Half of the donation programs reported conducting trainings as a part of their donation program. Twenty-six (76 %) programs reported that they conduct routine monitoring of their donation programs. Less than 30 % of donation programs were evaluated for their impact on health. Lack of technical staff and lack of funding were reported as key barriers to conducting impact evaluations. Member organizations of PQMD provide a broad range of medical donations, targeting a wide range of public health issues and events. While some level of monitoring and evaluation was conducted in nearly 80 % of the donation programs, a program's impact was infrequently evaluated. Opportunities exist to develop consistent metrics for medical donation programs, develop a common framework for impact evaluations, and advocate for data collection and analysis plans that collect meaningful metrics.

    Mercadal, Santiago; Cortés-Romera, Montserrat; Vélez, Patricia; Climent, Fina; Gámez, Cristina; González-Barca, Eva


    To evaluate the role of positron emission tomography combined with computed tomography (PET-CT) in the initial evaluation and response assessment in primary central nervous system lymphoma (PCNSL). Fourteen patients (8 males) with a median age 59.5 years diagnosed of PCNSL. A brain PET-CT and magnetic resonance imaging (MRI) were performed in the initial evaluation. In 7 patients a PET-CT after treatment was performed. PET-CT showed at diagnosis 31 hypermetabolic focuses and MRI showed 47 lesions, with a good grade of concordance between both (k = 0.61; P = .005). In the response assessment, correlation between both techniques was good, and PET-CT was helpful in the appreciation of residual MRI lesions. Overall survival at 2 years of negative vs. positive PET-CT at the end of treatment was 100 vs. 37.5%, respectively (P = .045). PET-CT can be useful in the initial evaluation of PCNSL, and especially in the assessment of response. Despite the fact that PET-CT detects less small lesions than MRI, a good correlation between MRI and PET-CT was observed. It is effective in the evaluation of residual lesions. Prospective studies are needed to confirm their possible prognostic value. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

  9. Chemical assessment state of the science: Evaluation of 32 decision-support tools used to screen and prioritize chemicals. (United States)

    Gauthier, Alison M; Fung, Mai; Panko, Julie; Kingsbury, Tony; Perez, Angela L; Hitchcock, Kristen; Ferracini, Tyler; Sahmel, Jennifer; Banducci, Amber; Jacobsen, Megan; Abelmann, Anders; Shay, Erin


    The last decade has seen an increased focus on evaluating the safety and sustainability of chemicals in consumer and industrial products. In order to effectively and accurately evaluate safety and sustainability, tools are needed to characterize hazard, exposure, and risk pertaining to products and processes. Because many of these tools will be used to identify problematic chemistries, and because many have potential applications in various steps of an alternatives analysis, the limitations and capabilities of available tools should be understood by users so that, ultimately, potential chemical risk is accurately reflected. In our study, we examined 32 chemical characterization tools from government, industry, academia, and non-governmental organizations (NGOs). The tools we studied were diverse, and varied widely in their scope and assessment. As such, they were separated into five categories for comparison: 1) Screening and Prioritization; 2) Database Utilization; 3) Hazard Assessment; 4) Exposure and Risk Assessment; and 5) Certification and Labeling. Each tool was scored based on our weighted set of criteria, and then compared to other tools in the same category. Ten tools received a high score in one or more categories; 24 tools received a medium score in one or more categories, and five tools received a low score in one or more categories. Although some tools were placed into more than one category, no tool encompassed all five of the assessment categories. Though many of the tools evaluated may be useful for providing guidance for hazards - and, in some cases, exposure - few tools characterize risk. To our knowledge, this study is the first to critically evaluate a large set of chemical assessment tools and provide an understanding of their strengths and limitations. © 2015 SETAC.

  11. Assessment and evaluation of the high risk neonate: the NICU Network Neurobehavioral Scale. (United States)

    Lester, Barry M; Andreozzi-Fontaine, Lynne; Tronick, Edward; Bigsby, Rosemarie


    There has been a long-standing interest in the assessment of the neurobehavioral integrity of the newborn infant. The NICU Network Neurobehavioral Scale (NNNS) was developed as an assessment for the at-risk infant. These are infants who are at increased risk for poor developmental outcome because of insults during prenatal development, such as substance exposure or prematurity or factors such as poverty, poor nutrition or lack of prenatal care that can have adverse effects on the intrauterine environment and affect the developing fetus. The NNNS assesses the full range of infant neurobehavioral performance including neurological integrity, behavioral functioning, and signs of stress/abstinence. The NNNS is a noninvasive neonatal assessment tool with demonstrated validity as a predictor, not only of medical outcomes such as cerebral palsy diagnosis, neurological abnormalities, and diseases with risks to the brain, but also of developmental outcomes such as mental and motor functioning, behavior problems, school readiness, and IQ. The NNNS can identify infants at high risk for abnormal developmental outcome and is an important clinical tool that enables medical researchers and health practitioners to identify these infants and develop intervention programs to optimize the development of these infants as early as possible. The video shows the NNNS procedures, shows examples of normal and abnormal performance and the various clinical populations in which the exam can be used.

  13. Evaluation and Quantification of Uncertainty in the Modeling of Contaminant Transport and Exposure Assessment at a Radioactive Waste Disposal Site (United States)

    Tauxe, J.; Black, P.; Carilli, J.; Catlett, K.; Crowe, B.; Hooten, M.; Rawlinson, S.; Schuh, A.; Stockton, T.; Yucel, V.


    The disposal of low-level radioactive waste (LLW) in the United States (U.S.) is a highly regulated undertaking. The U.S. Department of Energy (DOE), itself a large generator of such wastes, requires a substantial amount of analysis and assessment before permitting disposal of LLW at its facilities. One of the requirements that must be met in assessing the performance of a disposal site and technology is that a Performance Assessment (PA) demonstrate "reasonable expectation" that certain performance objectives, such as dose to a hypothetical future receptor, not be exceeded. The phrase "reasonable expectation" implies recognition of uncertainty in the assessment process. In order for this uncertainty to be quantified and communicated to decision makers, the PA computer model must accept probabilistic (uncertain) input (parameter values) and produce results which reflect that uncertainty as it is propagated through the model calculations. The GoldSim modeling software was selected for the task due to its unique facility with both probabilistic analysis and radioactive contaminant transport. Probabilistic model parameters range from water content and other physical properties of alluvium to the activity of radionuclides disposed to the amount of time a future resident might be expected to spend tending a garden. Although these parameters govern processes which are defined in isolation as rather simple differential equations, the complex interaction of couple processes makes for a highly nonlinear system with often unanticipated results. The decision maker has the difficult job of evaluating the uncertainty of modeling results in the context of granting permission for LLW disposal. This job also involves the evaluation of alternatives, such as the selection of disposal technologies. Various scenarios can be evaluated in the model, so that the effects of, for example, using a thicker soil cap over the waste cell can be assessed. This ability to evaluate mitigation

    Neurobehavioral tests have long been used to assess health effects in exposed working adult populations. The heightened concern over the potential impact of environmental exposures on neurological functioning in children has led to the development of test batteries for use with children. There is a need for reliable, easy-to-administer batteries to assess neurotoxic exposure in children. One such test battery previously validated with Spanish- and English-speaking children ages 4 and older, combines computerized tests from the Behavioral Assessment and Research System (BARS) with non-computerized tests. The goal of the present study was to determine the feasibility of using standardized neurobehavioral tests in preschool and school-aged Filipino children. Test instructions were translated into the vernacular, Tagalog or Tagalog-English ("Taglish") and some instructions and materials were modified to be appropriate for the target populations. The battery was administered to 4-6-year-old Filipino children (N=50). The performance of the Filipino children was compared to data previously collected from Spanish- and English-speaking children tested in the US. The majority of children had no difficulty completing the tests in the battery with the exception of the Symbol-Digit test and Digit Span-reverse. The three groups showed similar patterns of performance on the tests and the older children performed better than the younger children on all of the tests. The findings from this study demonstrate the utility of using this test battery to assess cognitive and motor performance in Filipino children. Tests in the battery assess a range of functions and the measures are sensitive to age differences. The current battery has been utilized in several cultures and socio-economic status classes, with only minor modifications needed. This study demonstrates the importance of pilot testing the methods before use in a new population, to ensure that the test is valid for that culture.

    Full Text Available Probiotics containing food supplements available in Bangladesh market were identified and collected for assessment. To assess their label claim, they were resuspended into sterile distilled water. Then, series dilutions of each sample solution were prepared and immediately plated out, in duplicate, into De Man Rogosa Sharpe (MRS agar. These plates were then incubated at 37°C for 48 hours and colonies were counted. Viable cell numbers stated on the labels were compared with actual viable cell numbers. To assess the viability of the probiotics included in the products, probiotic strains were isolated from each of the four products and screened for inhibitory activity against six indicator strains. It was surprisingly found that although the viable cell numbers of all supplements were three to four log cycles lower than label claim of the products, however, this problem did not affect the inhibitory activity of the probiotic strains against indicator strains according to in vitro assessment. Legislation and regulation regarding prebiotic-probiotic containing products should be built up in Bangladesh to ensure quality products supply to the consumers. Moreover, manufacturers of probiotic containing products should take the responsibility for providing the consumer with scientifically and legally correct information.

    Assess the validity and reproducibility of the updated version of the French causality assessment method in conditions approaching real-life use. A random sample of 31 drug-event pairs from the French pharmacovigilance database was assessed by the consensual judgement of three experts (gold standard). Separately, a team from a pharmacovigilance centre (PhVC) and another from a pharmaceutical company assessed these pairs using the current method, then with the updated method. To test the inter- and intra-rater reproducibility, two seniors and two juniors from a PhVC and a pharmaceutical company assessed the pairs twice with the updated method. A weighted kappa coefficient was used to measure the agreement of the two causality assessment methods with the consensual expert judgement (validity) as well as the agreement of the updated causality assessment over time (intra-rater reproducibility) and between evaluators (inter-rater reproducibility). Agreement between the current method and consensual expert judgement was fair for the PhVC team (weighted kappa [Kw] 0.33) and moderate for the pharmaceutical company team (Kw 0.41). For the updated method, agreement was better for both the PhVC (Kw 0.58) and the pharmaceutical company (Kw 0.52) teams. The inter- and intra-rater reproducibility of the updated method based on the intrinsic imputability was satisfactory overall (Kw 0.30-0.91). Discrepancies between evaluations from PhVC and pharmaceutical companies were observed with the updated method. The updated method performed better than the current one for drug causality assessment, suggesting that it should be used in routine pharmacovigilance. © 2015 Société Française de Pharmacologie et de Thérapeutique.

  2. A tiered asthma hazard characterization and exposure assessment approach for evaluation of consumer product ingredients. (United States)

    Maier, Andrew; Vincent, Melissa J; Parker, Ann; Gadagbui, Bernard K; Jayjock, Michael


    Asthma is a complex syndrome with significant consequences for those affected. The number of individuals affected is growing, although the reasons for the increase are uncertain. Ensuring the effective management of potential exposures follows from substantial evidence that exposure to some chemicals can increase the likelihood of asthma responses. We have developed a safety assessment approach tailored to the screening of asthma risks from residential consumer product ingredients as a proactive risk management tool. Several key features of the proposed approach advance the assessment resources often used for asthma issues. First, a quantitative health benchmark for asthma or related endpoints (irritation and sensitization) is provided that extends qualitative hazard classification methods. Second, a parallel structure is employed to include dose-response methods for asthma endpoints and methods for scenario specific exposure estimation. The two parallel tracks are integrated in a risk characterization step. Third, a tiered assessment structure is provided to accommodate different amounts of data for both the dose-response assessment (i.e., use of existing benchmarks, hazard banding, or the threshold of toxicological concern) and exposure estimation (i.e., use of empirical data, model estimates, or exposure categories). Tools building from traditional methods and resources have been adapted to address specific issues pertinent to asthma toxicology (e.g., mode-of-action and dose-response features) and the nature of residential consumer product use scenarios (e.g., product use patterns and exposure durations). A case study for acetic acid as used in various sentinel products and residential cleaning scenarios was developed to test the safety assessment methodology. In particular, the results were used to refine and verify relationships among tiered approaches such that each lower data tier in the approach provides a similar or greater margin of safety for a given

    Habash, Riadh W Y; Brodsky, Lynn M; Leiss, William; Krewski, Daniel; Repacholi, Michael


    Exposure to electric and magnetic fields (EMF) emanating from the generation, distribution, and utilization of electricity is widespread. The major debate in recent years has focused on the possibility that exposure to EMF may result in adverse health consequences, including the development of cancer. This article provides a review and evaluation of potential health risks associated with residential and occupational exposure to EMF. In addition to reviewing data from laboratory, epidemiology, and clinical studies, we examine exposure data from field measurement surveys and exposure guidelines that have been established for EMF. Currently, the evidence in support of an association between EMF and childhood cancer is limited, although this issue warrants further investigation. Evidence of an association between EMF exposure and adult cancers, derived largely from occupational settings, is inconsistent, precluding clear conclusions. There is little evidence of an association between EMF and noncancer health effects. Epidemiological studies of EMF and population health are limited by exposure measurement error and the lack of a clear dose/response relationship in studies suggesting possible health risks. Further research is needed to clarify the ambiguous findings from present studies and to determine if EMF exposure poses a health risk.

  7. Evaluating an Introductory Geoscience Classroom Exercise using Pre- and Post-Exercise Assessments (United States)

    Shipp, S.; Henning, A. T.; Sawyer, D. S.


    Discovering Plate Boundaries is a data-rich classroom exercise that has been used successfully in middle school, high school, and college-level science classes. It is an active learning exercise that encourages students to discover the theory of plate tectonics based on their observations of maps containing earthquake, volcano, topography, and seafloor age data. Students and educators have responded with enthusiasm to this exercise, especially the jigsaw component that promotes random group interaction. We now focus our attention on assessing the impact of the exercise on student learning in order to determine whether it conveys sufficient content knowledge. We designed a pre-exercise assessment consisting of questions relating to introductory geoscience concepts, with particular emphasis on plate tectonics. These questions were based on student learning goals for introductory geoscience courses that utilize the Discovering Plate Boundaries exercise. The questions have evolved with repeated use in order to more effectively gauge student knowledge. The pre-exercise assessments have been completed by middle school, high school, and college students, and have identified some common student misconceptions about geoscience. For example, many students believe that earthquakes are a key component of mountain-building, while volcanoes are not. This type of information should be used by the instructor to stress certain concepts during the course in order to address these preconceived notions. A post-exercise assessment consisting of the same questions was administered at the end of the courses and we found that some of the initial misconceptions remained. We conclude that more pre-exercise assessments should be administered in order to establish a database of student misconceptions so that educators can focus instruction in these areas.

  8. Development and evaluation of a novel smart device-based application for burn assessment and management. (United States)

    Godwin, Zachary; Tan, James; Bockhold, Jennifer; Ma, Jason; Tran, Nam K


    We have developed a novel software application that provides a simple and interactive Lund-Browder diagram for automatic calculation of total body surface area (TBSA) burned, fluid formula recommendations, and serial wound photography on a smart device platform. The software was developed for the iPad (Apple, Cupertino, CA) smart device platforms. Ten burns ranging from 5 to 95% TBSA were computer generated on a patient care simulator using Adobe Photoshop CS6 (Adobe, San Jose, CA). Burn clinicians calculated the TBSA first using a paper-based Lund-Browder diagram. Following a one-week "washout period", the same clinicians calculated TBSA using the smart device application. Simulated burns were presented in a random fashion and clinicians were timed. Percent TBSA burned calculated by Peregrine vs. the paper-based Lund-Browder were similar (29.53 [25.57] vs. 28.99 [25.01], p=0.22, n=7). On average, Peregrine allowed users to calculate burn size significantly faster than the paper form (58.18 [31.46] vs. 90.22 [60.60]s, pphotography capabilities, and acute burn resuscitation fluid calculator. We developed an innovative smart device application that enables accurate and rapid burn size assessment to be cost-effective and widely accessible. Copyright © 2014 Elsevier Ltd and ISBI.

  9. Application of the characteristic function to evaluate and compare analytical variability in an external quality assessment scheme for serum ethanol. (United States)

    Coucke, Wim; Charlier, Corine; Lambert, Willy; Martens, Frank; Neels, Hugo; Tytgat, Jan; Van de Walle, Philippe; Vanescote, André; Wallemacq, Pierre; Wille, Sarah; Verstraete, Alain G


    As a cornerstone of quality management in the laboratory, External Quality Assessment (EQA) schemes are used to assess laboratory and analytical method performance. The characteristic function is used to describe the relation between the target concentration and the EQA standard deviation, which is an essential part of the evaluation process. The characteristic function is also used to compare the variability of different analytical methods. We fitted the characteristic function to data from the Belgian External Quality Assessment program for serum ethanol. Data included results from headspace gas chromatography and the enzymatic methods of Abbott, Roche, Siemens, and Ortho-Clinical Diagnostics. We estimated the characteristic function with weighted nonlinear regression. By introducing dummy variables, we rewrote the original formula of the characteristic function to assess statistical inference for comparing the variability of the different analytical methods. The characteristic function fitted the data precisely. Comparison between methods showed that there was little difference between the estimated variability for low concentrations, and that the increase in SD with increasing target concentration was slower for Abbott and Roche than for the other methods. The characteristic function can successfully be introduced in clinical schemes, although its applicability to fit the data should always be assessed. Because of its easy parameterization, it can be used to assess differences in performance between analytical methods and to assess laboratory performance. The characteristic function also offers an alternative framework for coefficients of variation to describe variability of analytical methods. © 2015 American Association for Clinical Chemistry.

  10. Telemedicine and the evaluation of cognitive impairment: the additive value of neuropsychological assessment. (United States)

    Harrell, Kathryn M; Wilkins, Stacy S; Connor, Megan K; Chodosh, Joshua


    The number of people in the United States living with dementia is projected to rise to over 7.1 million in the next 12 years, representing a 40% increase from current levels. This anticipated "dementia tsunami" has led to a recent state and national policy emphasis on early detection, improved care quality, reduced caregiver burden, and increased access to care. The ability to achieve these objectives is limited by few dementia specialists in rural and small communities and the challenges of travel to and within congested urban regions for dementia patients and their caregivers. Telemedicine is one such means for responding to this lack of access to subspecialty assessment and care. We describe our early experiences with this technology applied to neuropsychological assessments, with data from 31 patients. As part of an interdisciplinary dementia care demonstration project, clinical video teleconferencing provides real-time high resolution video interactions between dementia subspecialists in a major metropolitan medical center and patients in 3 outlying clinics located 180, 150, and 100 miles away. Comprehensive neuropsychological assessments, designed to address referral questions related to neurocognitive disorders via clinical video teleconferencing, are conducted as one component of interdisciplinary care. Eighty-seven percent of patients referred for neuropsychological assessment had an inaccurate neurocognitive diagnosis at the time of referral. Unmet and unrecognized mental health treatment needs were identified in over 77% of patients. In addition, acceptance was good for patients, caregivers, and clinicians. Teleneuropsychology is proving to be an excellent resource for clarifying cognitive and psychiatric diagnoses, and integrating individual strengths, weaknesses, and preferences into treatment and care plans used by other health care providers, patients, and caregivers.

Using both exploratory factor analysis (EFA and Rasch modeling, the authors investigate the (a an overall assessment of dimensionality using EFA, (b a secondary assessment of dimensionality using a principal components analysis (PCA of the residuals when the items are fit to the Rasch model, and (c an assessment of item-level properties using item-level statistics provided when the items are fit to the Rasch model. The results support the usage of the scale as a supplement to high-stakes decision making such as tenure. However, the lack of precise targeting of item difficulty to person ability combined with the low person separation index renders rank-ordering professors according to minuscule differences in overall subscale scores a highly questionable practice.

  12. Evaluation of colloid transport issues and recommendations for SKI performance assessments

    Energy Technology Data Exchange (ETDEWEB)

    Wickham, S. M.; Bennett, D. G.; Higgo, J. J. W. [Galson Sciences Ltd., Oakham (United Kingdom)


    The primary objective of this project was to develop recommendations to SKI for evaluating the potential significance of colloids in performance assessment (PA) studies by: Updating a previous review of the treatment of colloids in PA studies for radioactive waste repositories and to include information on PAs published in the period 1997-1999. We have reviewed sixteen PAs conducted in nine countries and have made the following observations: All PAs include colloid formation and colloid transport in their FEP list. Although some programmes have deferred consideration of colloidal radionuclide transport until further research has been performed, more recent PAs do account for the effects of colloids. PAs of disposal systems in which the waste canister is surrounded by a bentonite buffer do not consider the effect of colloids on the source term. These PAs assume that all colloids are filtered by the bentonite buffer and cannot escape from the near-field. PAs of disposal systems with no bentonite buffer have to account for mobilisation of radionuclides from the waste by colloids. The concentration of colloids that may form in the repository is a key uncertainty. Many PA programmes have modelled colloidal radionuclide transport in the geosphere using one-dimensional transport equations. No PA has included a comprehensive treatment of colloid transport using mechanistic modelling. Some PAs have not undertaken modelling of colloid transport in the geosphere, but have relied instead on arguments that such transport processes will be of low consequence to the performance of the disposal system. Five PAs have shown the effects of colloid transport through the geosphere to be potentially significant. For the disposal of spent nuclear fuel, SKB has developed the KBS-3 concept. For the disposal of long-lived low-level and intermediate-level radioactive waste, SKB has developed the SFL 3-5 concept. In the SFL 3-5 concept, waste is placed in underground disposal caverns and

    Morina, Naser; Ewers, Simon M; Passardi, Sandra; Schnyder, Ulrich; Knaevelsrud, Christine; Müller, Julia; Bryant, Richard A; Nickerson, Angela; Schick, Matthis


    Mental health problems resulting from persecution and forced migration are very common among refugees and asylum seekers and evolve into a major public health challenge in hosting societies. Language barriers often prevent timely access to appropriate health care, leading to chronic trajectories and abortive social integration. Tools for multilingual screening and assessment could be of great benefit for this particularly vulnerable population as well as for policy makers. This study aimed at testing the reliability, feasibility and usability of the Multi-Adaptive Psychological Screening Software (MAPSS), a newly developed Audio Computer-Assisted Self-Interview Software (ACASI) for touchscreen devices, for screening purposes in a clinical setting. In a randomized cross-over design including both MAPSS and paper-pencil clinician-administered interviews, 30 treatment-seeking refugees completed clinical measures and a feasibility questionnaire to rate the user interface of MAPSS. Five professionals performed given tasks in MAPSS and completed usability questionnaires for the administration interface. Results showed no differences between the two assessment modalities with regard to symptom scores. The findings suggest good feasibility and usability of MAPSS in traumatized refugees. The administration via MAPSS was significantly shorter than the paper-pencil interview. MAPSS may be a cost-effective, flexible and valid alternative to interpreter-based psychometric screening and assessment.

  14. Population-relevant endpoints in the evaluation of endocrine-active substances (EAS) for ecotoxicological hazard and risk assessment. (United States)

    Marty, Mary S; Blankinship, Amy; Chambers, Janice; Constantine, Lisa; Kloas, Werner; Kumar, Anupama; Lagadic, Laurent; Meador, James; Pickford, Daniel; Schwarz, Tamar; Verslycke, Tim


    For ecotoxicological risk assessment, endocrine disruptors require the establishment of an endocrine mode of action (MoA) with a plausible link to a population-relevant adverse effect. Current ecotoxicity test methods incorporate mostly apical endpoints although some also include mechanistic endpoints, subcellular-through-organ level, which can help establish an endocrine MoA. However, the link between these endpoints and adverse population-level effects is often unclear. The case studies of endocrine-active substances (EAS) (tributyltin, ethinylestradiol, perchlorate, trenbolone, propiconazole, and vinclozolin) evaluated from the Society of Environmental Toxicology and Chemistry (SETAC) Pellston Workshop ® "Ecotoxicological Hazard and Risk Assessment Approaches for Endocrine-Active Substances (EHRA)" were used to evaluate the population relevance of toxicity endpoints in various taxa according to regulatory endocrine-disruptor frameworks such as the Organisation for Economic Co-operation and Development (OECD) Conceptual Framework for Testing and Assessment of Endocrine Disruptors. A wide variety of potentially endocrine-relevant endpoints were identified for mollusks, fish, amphibians, birds, and mammals, although the strength of the relationship between test endpoints and population-level effects was often uncertain. Furthermore, testing alone is insufficient for assessing potential adaptation and recovery processes in exposed populations. For this purpose, models that link effects observed in laboratory tests to the dynamics of wildlife populations appear to be necessary, and their development requires reliable and robust data. As our understanding of endocrine perturbations and key event relationships improves, adverse population-level effects will be more easily and accurately predicted.

  16. Local scale multiple quantitative risk assessment and uncertainty evaluation in a densely urbanised area (Brescia, Italy) (United States)

    Lari, S.; Frattini, P.; Crosta, G. B.


    The study of the interactions between natural and anthropogenic risks is necessary for quantitative risk assessment in areas affected by active natural processes, high population density and strong economic activities. We present a multiple quantitative risk assessment on a 420 km2 high risk area (Brescia and surroundings, Lombardy, Northern Italy), for flood, seismic and industrial accident scenarios. Expected economic annual losses are quantified for each scenario and annual exceedance probability-loss curves are calculated. Uncertainty on the input variables is propagated by means of three different methodologies: Monte-Carlo-Simulation, First Order Second Moment, and point estimate. Expected losses calculated by means of the three approaches show similar values for the whole study area, about 64 000 000 € for earthquakes, about 10 000 000 € for floods, and about 3000 € for industrial accidents. Locally, expected losses assume quite different values if calculated with the three different approaches, with differences up to 19%. The uncertainties on the expected losses and their propagation, performed with the three methods, are compared and discussed in the paper. In some cases, uncertainty reaches significant values (up to almost 50% of the expected loss). This underlines the necessity of including uncertainty in quantitative risk assessment, especially when it is used as a support for territorial planning and decision making. The method is developed thinking at a possible application at a regional-national scale, on the basis of data available in Italy over the national territory.

    Culturally sensitive and valid assessments of participation in occupations are needed for Spanish-speaking children to enhance services offered to this population. The purpose of this study was to assess the validity and reliability of the newly developed Spanish version of the Children's Assessment of Participation and Enjoyment and Preferences for Activities of Children, the Evaluación de Participacion y Disfrute de los Niños y Preferencias de las Actividades de los Niños (EPDN/PAN). The sample included 249 children with and without disabilities, aged 6 to 15 years. Statistically significant differences (p < 0.05) in the participation of children with disabilities and children without disabilities, and between younger and older children were found. No statistical significant differences were found between males and females in the dimensions of participation assessed. Adequate internal consistency (0.70-0.92) was found for the PAN scale and the Overall and Informal domain scores of the EPDN-Intensity scale. Further study is needed to evaluate the formal domain scale and gender differences by activity types.

  18. Evaluation of Stochastic Rainfall Models in Capturing Climate Variability for Future Drought and Flood Risk Assessment (United States)

    Chowdhury, A. F. M. K.; Lockart, N.; Willgoose, G. R.; Kuczera, G. A.; Kiem, A.; Nadeeka, P. M.


    One of the key objectives of stochastic rainfall modelling is to capture the full variability of climate system for future drought and flood risk assessment. However, it is not clear how well these models can capture the future climate variability when they are calibrated to Global/Regional Climate Model data (GCM/RCM) as these datasets are usually available for very short future period/s (e.g. 20 years). This study has assessed the ability of two stochastic daily rainfall models to capture climate variability by calibrating them to a dynamically downscaled RCM dataset in an east Australian catchment for 1990-2010, 2020-2040, and 2060-2080 epochs. The two stochastic models are: (1) a hierarchical Markov Chain (MC) model, which we developed in a previous study and (2) a semi-parametric MC model developed by Mehrotra and Sharma (2007). Our hierarchical model uses stochastic parameters of MC and Gamma distribution, while the semi-parametric model uses a modified MC process with memory of past periods and kernel density estimation. This study has generated multiple realizations of rainfall series by using parameters of each model calibrated to the RCM dataset for each epoch. The generated rainfall series are used to generate synthetic streamflow by using a SimHyd hydrology model. Assessing the synthetic rainfall and streamflow series, this study has found that both stochastic models can incorporate a range of variability in rainfall as well as streamflow generation for both current and future periods. However, the hierarchical model tends to overestimate the multiyear variability of wet spell lengths (therefore, is less likely to simulate long periods of drought and flood), while the semi-parametric model tends to overestimate the mean annual rainfall depths and streamflow volumes (hence, simulated droughts are likely to be less severe). Sensitivity of these limitations of both stochastic models in terms of future drought and flood risk assessment will be discussed.

    This study establishes the concurrent validity, predictive validity, and responsiveness of the Revised Nottingham Sensation Assessment (rNSA) during rehabilitation for people with stroke. The study recruited 147 patients with stroke. The main assessment used was the rNSA, and outcome measures were the Fugl-Meyer Assessment sensory subscale (FMA-S) and motor subscale (FMA-M) and the Nottingham Extended Activities of Daily Living (NEADL) scale. Correlation coefficients were good to excellent between the rNSA and the FMA-S. The rNSA proprioception measure was a predictor for the FMA-S. The rNSA stereognosis and tactile-pinprick measures for the proximal upper limb were predictors for the FMA-M and the NEADL scale, respectively. Responsiveness was moderate to large for three subscales of the rNSA (standardized response mean = .51-.83). This study may support the concurrent validity, predictive validity, and responsiveness of the rNSA for people with stroke. Copyright © 2016 by the American Occupational Therapy Association, Inc.

    The pulmonary fibrosis extent in systemic sclerosis (SSc) has a prognostic value. Chest Computed Tomography (CT) is the gold standard to detect an interstitial lung disease (ILD). Semi-quantitative scores and quantitative methods can estimate the ILD. The first ones have a considerable inter-intraobserver variability, while quantitative scores, based on distribution of lung attenuation parameters (also called CT indexes), can be obtained through expensive and not so user-friendly software. The aim of this work is to investigate whether a DICOM-viewer open-source software (OsiriX) can obtain CT indexes correlating with semi-quantitative scores. Sixty-three chest CTs of ILD-SSc patients were assessed with two semi-quantitative methods (visual extent and limited/extensive ILD grading) and then blindly processed with OsiriX to obtain the distribution parameters of lung attenuation (kurtosis, skewness and mean). Semiquantitative assessment and CT indexes were compared through the Spearman rank test and Mann-Whitney test. All CT indexes showed a statistically significant correlation of moderate degree with the visual extent semi-quantitative assessment (p-value less than 0.05). Skewness was the lung attenuation distribution parameter with the strongest correlation (r =-0.378, p-value = 0.0023). Moreover, CT indexes of patients with an extensive and limited disease were statistically different (p less than 0.01). CT indexes correlating with a radiological semi-quantitative ILD assessment can be obtained through OsiriX. CT indexes can be considered very helpful to discriminate patients with extensive and limited ILD.

  2. Video-based self-assessment: implementation and evaluation in an undergraduate nursing course. (United States)

    Yoo, M S; Son, Y J; Kim, Y S; Park, J H


    This research was performed to investigate the effects of video-based self-assessment on the ability of nursing students to accurately measure vital signs, their communication skills, and their satisfaction. This research was conducted between March 2007 and June 2007 as a quasi-experimental control-group, pretest-posttest design. The study population was composed of 40 second-year student nurses who enrolled in a fundamentals of nursing course of a college of nursing, Ajou University in Korea. Results of the research indicate that there was a statistically significant difference in exam scores for assessing long-term memory video-review group demonstrating higher scores. Student satisfaction was also significantly higher in the video-review group than in the control group. These results may suggest video-based self-assessment is a beneficial and effective instructional method of training undergraduate nursing students to develop awareness of their strengths and weaknesses, and to improve their clinical and communication skills.

  3. Three-year outcomes of cultured limbal epithelial allografts in aniridia and Stevens-Johnson syndrome evaluated using the Clinical Outcome Assessment in Surgical Trials assessment tool. (United States)

    Limbal stem cell deficiency (LSCD) is an eye disorder in which the stem cells responsible for forming the surface skin of the cornea are destroyed by disease. This results in pain, loss of vision, and a cosmetically unpleasant appearance. Many new treatments, including stem cell therapies, are emerging for the treatment of this condition, but assessment of these new technologies is severely hampered by the lack of biomarkers for this disease or validated tools for assessing its severity. The aims of this study were to design and test the reliability of a tool for grading LSCD, to define a set of core outcome measures for use in evaluating treatments for this condition, and to demonstrate their utility. This was achieved by using our defined outcome set (which included the Clinical Outcome Assessment in Surgical Trials of Limbal stem cell deficiency [COASTL] tool) to evaluate the 3-year outcomes for allogeneic ex vivo cultivated limbal epithelial transplantation (allo-CLET) in patients who had bilateral total LSCD secondary to aniridia or Stevens-Johnson syndrome. The results demonstrate that our new grading tool for LSCD, the COASTL tool, is reliable and repeatable, and that improvements in the biomarkers used in this tool correlate positively with improvements in visual acuity. The COASTL tool showed that following allo-CLET there was a decrease in LSCD severity and an increase in visual acuity up to 12 months post-treatment, but thereafter LSCD severity and visual acuity progressively deteriorated.

  4. Preoperative evaluation and comprehensive risk assessment for children with Down syndrome. (United States)

    Lewanda, Amy Feldman; Matisoff, Andrew; Revenis, Mary; Harahsheh, Ashraf; Futterman, Craig; Nino, Gustavo; Greenberg, Jay; Myseros, John S; Rosenbaum, Kenneth N; Summar, Marshall


    Down syndrome is a common chromosome disorder affecting all body systems. This creates unique physiologic concerns that can affect safety during anesthesia and surgery. Little consensus exists, however, on the best way to evaluate children with Down syndrome in preparation for surgery. We review a number of salient topics affecting these children in the perioperative period, including cervical spine instability, cardiovascular abnormalities, pulmonary hypertension, upper airway obstruction, hematologic disturbances, prematurity, low birth weight, and the use of supplements and alternative therapies. Recommendations include obtaining a complete blood count to detect an increased risk for bleeding or stroke, and cardiology evaluation to identify patients with pulmonary hypertension, as well as undiagnosed or residual heart disease. Pediatric cardiac anesthesiologists and intensivists should be involved as needed. The potential for cervical spine instability should be considered, and the anesthesiologist may wish to have several options available both for the medications and equipment used. The child's family should always be asked if he or she is on any nutritional supplements, as some products marketed to families may have secondary effects such as inhibition of platelet function. Using this evaluation in presurgical planning will allow physicians to better consider the individual circumstances for their patients with Down syndrome. Our goal was to optimize patient safety by choosing the most appropriate setting and perioperative personnel, and to mitigate those risk factors amenable to intervention. © 2016 John Wiley & Sons Ltd.

    The quantity and frequency of alcohol consumption are crucial both in risk assessment as well as epidemiological and clinical research. Using the Munich Composite International Diagnostic Interview (M-CIDI), drinking amounts have been assessed in numerous large-scale studies. However, the accuracy of this assessment has rarely been evaluated. This study evaluates the relevance of drink categories and pouring sizes, and the factors used to convert actual drinks into standard drinks. We compare the M-CIDI to alternative drink assessment instruments and empirically validate drink categories using a general population sample (n = 3165 from Germany), primary care samples (n = 322 from Italy, n = 1189 from Germany), and a non-representative set of k = 22503 alcoholic beverages sold in Germany in 2010-2016. The M-CIDI supplement sheet displays more categories than other instruments (AUDIT, TLFB, WHO-CIDI). Beer, wine, and spirits represent the most prevalent categories in the samples. The suggested standard drink conversion factors were inconsistent for different pouring sizes of the same drink and, to a smaller extent, across drink categories. For the use in Germany and Italy, we propose the limiting of drink categories and pouring sizes, and a revision of the proposed standard drinks. We further suggest corresponding examinations and revisions in other cultures. © 2017 The Authors International Journal of Methods in Psychiatric Research Published by John Wiley & Sons Ltd.

  12. Toward holistic evaluation and assessment: linking ecosystems and human well-being for the three gorges dam. (United States)

    Kittinger, John N; Coontz, Kristopher M; Yuan, Zhanpeng; Han, Deju; Zhao, Xianfu; Wilcox, Bruce A


    A significant challenge exists in assessing the social and ecological impacts of development projects in a holistic and comprehensive manner. Our objective is to elucidate the linkages between ecological change and human well-being, and its importance in integrated assessment policy for development projects, using the Three Gorges Dam (China) as a case study. A collaborative research initiative was undertaken to review and synthesize published information on the ecological and human health effects of the Three Gorges Dam. Our synthesis suggests that the Three Gorges Dam has altered social-ecological dynamics of human health and ecosystem function in the Yangtze River basin with significant consequences for human well-being. Direct impacts to human well-being were grouped into four primary categories, including: (1) toxicological impacts; (2) shifting infectious disease dynamics; (3) natural hazards; and (4) social health. Social-ecological relationships were altered in complex ways, with both direct and indirect effects, positive and negative interactions, and chronic and acute impacts on human well-being. Our synthesis supports a comprehensive evaluation of development projects via integrated assessments of human and environmental consequences. This is probably best achieved through a coupled social-environmental impact assessment to ensure holistic and comprehensive analyses of expected costs and benefits. The role of research can thereby be to elucidate the linkages between ecosystems and human health to better inform the assessment process. A synthesis of the existing information on the Three Gorges suggests that this is best achieved through institutional collaboration and transdisciplinary integration of expertise.

  13. Assessment of hemispheric asymmetry: Development and psychometric evaluation of a chimeric face test

    Directory of Open Access Journals (Sweden)

    Garima Gupta


    Full Text Available Background: Anomaly in hemispheric functioning has been linked with various psychiatric conditions. However, most of the procedures used to assess hemispheric asymmetry in clinical population require special training and/or complex procedures and some of the measures suffer from such methodological problems that undermine their utility for clinical use. Further, the available economical procedures such as chimeric face test (CFT utilize facial expression of emotions posed by western expressers and are therefore less valid measures in Indian context. Aim: Taking these limitations into account, the present study makes an attempt to develop a CFT (using facial affect photographs of Indian expressers as an alternative and economical procedure for the assessment of hemispheric asymmetry. Materials and Methods: Using the happy and neutral expressions of eight Indian expressers, 32 chimeric faces were developed by combining the half happy and half neutral expressions. These 32 chimeric faces were presented in pairs (arranged in top-bottom fashion in booklet form to 225 right-handed participants. Using the contemporary item analytic procedure, finally 22 pairs of chimeric faces that showed satisfactory psychometric properties were retained. These 22 pairs of chimeric faces formed the final CFT. The psychometric properties of the various items as well as that of the whole CFT were found satisfactory. Results: All the items were found reliable and valid as indicated by item-total correlation and alpha-if-item deleted. The internal consistency of the CFT was also found to be highly satisfactory (Cronbach′s alpha =.80. Further, the participants on the average showed a right hemispheric advantage on the CFT that provide support to its validity. The findings of intermediate analysis of the data of an ongoing project also provide preliminary evidence for the validity of the CFT. Conclusion : The CFT is a reliable and valid measure to assess hemispheric

  15. Health assessment of gasoline and fuel oxygenate vapors: micronucleus and sister chromatid exchange evaluations. (United States)

    Schreiner, Ceinwen A; Hoffman, Gary M; Gudi, Ramadevi; Clark, Charles R


    Micronucleus and sister chromatid exchange (SCE) tests were performed for vapor condensate of baseline gasoline (BGVC), or gasoline with oxygenates, methyl tert-butyl ether (G/MTBE), ethyl tert butyl ether (G/ETBE), t-amyl methyl ether (G/TAME), diisopropyl ether (G/DIPE), t-butyl alcohol (TBA), or ethanol (G/EtOH). Sprague Dawley rats (the same 5/sex/group for both endpoints) were exposed to 0, 2000, 10,000, or 20,000mg/m(3) of each condensate, 6h/day, 5days/week over 4weeks. Positive controls (5/sex/test) were given cyclophosphamide IP, 24h prior to sacrifice at 5mg/kg (SCE test) and 40mg/kg (micronucleus test). Blood was collected from the abdominal aorta for the SCE test and femurs removed for the micronucleus test. Blood cell cultures were treated with 5μg/ml bromodeoxyuridine (BrdU) for SCE evaluation. No significant increases in micronucleated immature erythrocytes were observed for any test material. Statistically significant increases in SCE were observed in rats given BGVC alone or in female rats given G/MTBE. G/TAME induced increased SCE in both sexes at the highest dose only. Although DNA perturbation was observed for several samples, DNA damage was not expressed as increased micronuclei in bone marrow cells. Inclusion of oxygenates in gasoline did not increase the effects of gasoline alone or produce a cytogenetic hazard. Copyright © 2014 Elsevier Inc. All rights reserved.

  16. Prospective comparative evaluation study of Laser Doppler Imaging and thermal imaging in the assessment of burn depth. (United States)

    Wearn, Christopher; Lee, Kwang Chear; Hardwicke, Joseph; Allouni, Ammar; Bamford, Amy; Nightingale, Peter; Moiemen, Naiem


    The accurate assessment of burn depth is challenging but crucial for surgical excision and tissue preservation. Laser Doppler Imaging (LDI) has gained increasing acceptance as a tool to aid depth assessment but its adoption is hampered by high costs, long scan times and limited portability. Thermal imaging is touted as a suitable alternative however few comparison studies have been done. Sixteen burn patients with 52 regions of interests were analysed. Burn depth was determined using four methods LDI, thermal imaging, photographic and real-time clinical evaluation at day 1 and day 3. LDI flux and Delta T values were used for the prediction of outcomes (wound closure in evaluation of burn depth was performed by 4 blinded burn surgeons. Accuracy of assessment methods were greater on post burn day 3 compared to day 0. Accuracies of LDI on post burn day 0 and 3 were 80.8% and 92.3% compared to 55.8% and 71.2% for thermal imaging and 62.5% and 71.6% for photographic clinical assessment. Real-time clinical examination had an accuracy of 88.5%. Thermal imaging scan times were significantly faster compared to LDI. LDI outperforms thermal imaging in terms of diagnostic accuracy of burn depth likely due to the susceptibility of thermal imaging to environmental factors. Crown Copyright © 2017.

  20. Local scale multiple quantitative risk assessment and uncertainty evaluation in a densely urbanised area (Brescia, Italy

    Directory of Open Access Journals (Sweden)

    S. Lari


    Full Text Available The study of the interactions between natural and anthropogenic risks is necessary for quantitative risk assessment in areas affected by active natural processes, high population density and strong economic activities.

    We present a multiple quantitative risk assessment on a 420 km2 high risk area (Brescia and surroundings, Lombardy, Northern Italy, for flood, seismic and industrial accident scenarios. Expected economic annual losses are quantified for each scenario and annual exceedance probability-loss curves are calculated. Uncertainty on the input variables is propagated by means of three different methodologies: Monte-Carlo-Simulation, First Order Second Moment, and point estimate.

    Expected losses calculated by means of the three approaches show similar values for the whole study area, about 64 000 000 € for earthquakes, about 10 000 000 € for floods, and about 3000 € for industrial accidents. Locally, expected losses assume quite different values if calculated with the three different approaches, with differences up to 19%.

    The uncertainties on the expected losses and their propagation, performed with the three methods, are compared and discussed in the paper. In some cases, uncertainty reaches significant values (up to almost 50% of the expected loss. This underlines the necessity of including uncertainty in quantitative risk assessment, especially when it is used as a support for territorial planning and decision making. The method is developed thinking at a possible application at a regional-national scale, on the basis of data available in Italy over the national territory.

  1. Evaluation of breathing pattern: comparison of a Manual Assessment of Respiratory Motion (MARM) and respiratory induction plethysmography. (United States)

    Courtney, Rosalba; van Dixhoorn, Jan; Cohen, Marc


    Altered breathing pattern is an aspect of dysfunctional breathing but few standardised techniques exist to evaluate it. This study investigates a technique for evaluating and quantifying breathing pattern, called the Manual Assessment of Respiratory Motion (MARM) and compares it to measures performed with Respiratory Induction Plethysmography (RIP). About 12 subjects altered their breathing and posture while 2 examiners assessed their breathing using the MARM. Simultaneous measurements with RIP were taken. Inter-examiner agreement and agreement between MARM and RIP were assessed. The ability of the measurement methods to differentiate between diverse breathing and postural patterns was compared. High levels of agreement between examiners were found with the MARM for measures of the upper rib cage relative to lower rib cage/abdomen motion during breathing but not for measures of volume. The measures of upper rib cage dominance during breathing correlated with similar measures obtained from RIP. Both RIP and MARM measures methods were able to differentiate between abdominal and thoracic breathing patterns, but only MARM was able to differentiate between breathing changes occurring as result of slumped versus erect sitting posture. This study suggests that the MARM is a reliable clinical tool for assessing breathing pattern.

  4. Assessing Students' Understandings of Biological Models and their Use in Science to Evaluate a Theoretical Framework (United States)

    Grünkorn, Juliane; Belzen, Annette Upmeier zu; Krüger, Dirk


    Research in the field of students' understandings of models and their use in science describes different frameworks concerning these understandings. Currently, there is no conjoint framework that combines these structures and so far, no investigation has focused on whether it reflects students' understandings sufficiently (empirical evaluation). Therefore, the purpose of this article is to present the results of an empirical evaluation of a conjoint theoretical framework. The theoretical framework integrates relevant research findings and comprises five aspects which are subdivided into three levels each: nature of models, multiple models, purpose of models, testing, and changing models. The study was conducted with a sample of 1,177 seventh to tenth graders (aged 11-19 years) using open-ended items. The data were analysed by identifying students' understandings of models (nature of models and multiple models) and their use in science (purpose of models, testing, and changing models), and comparing as well as assigning them to the content of the theoretical framework. A comprehensive category system of students' understandings was thus developed. Regarding the empirical evaluation, the students' understandings of the nature and the purpose of models were sufficiently described by the theoretical framework. Concerning the understandings of multiple, testing, and changing models, additional initial understandings (only one model possible, no testing of models, and no change of models) need to be considered. This conjoint and now empirically tested framework for students' understandings can provide a common basis for future science education research. Furthermore, evidence-based indications can be provided for teachers and their instructional practice.

  5. Effect on work ability after team evaluation of functioning regarding pain, self-rated disability, and work ability assessment. (United States)

    Norrefalk, Jan-Rickard; Littwold-Pöljö, Agneta; Ryhle, Leif; Jansen, Gunilla Brodda


    To evaluate the effect of a 1-2 week multiprofessional team assessment, without a real rehabilitation effort, 60 patients suffering from long-standing pain and on long-lasting time on sick leave were studied. A questionnaire concerning their daily activities, quality of life, pain intensity, sick-leave level, and their work state was filled out by all patients before starting the assessment and at a 1-year follow-up. The results from the assessment period and the multiprofessional team decision of the patient's working ability were compared with the actual working rate after 1 year. The follow-up showed a significant reduction of sick leave and a higher level of activity (P work. However, the team evaluation of the patient's work ability did not correlate to predict the actual outcome. The patient's pain intensity, life satisfaction, gender, age, ethnic background, and time absent from work before the start of the evaluation showed no correlation to reduction on time on sickness benefit level. These parameters could not be used as predictors in this study.

  6. An evaluation of a framework for facilitating and assessing physiotherapy students' reflection on practice. (United States)

    Donaghy, Marie; Morss, Kate


    Reflective practice is promoted in the health care professions as a developmental process leading to competent and effective practice, although the link between reflection and enhancement of physiotherapy practice remains speculative and conjectural. This article provides evidence that reflection can influence developing practice based on the evaluation of a reflective framework for students on clinical placement. The evaluation explored, in depth, students' experiences and perceptions of its benefits and limitations. Thematic analysis of response data from five focus groups (n = 43) representing three student cohorts resolved significant outcomes-related themes: personal insight, linking reflection to the physiotherapy process, and learning and personal change. Process-related themes focused on strengths and weaknesses of the framework and associated issues. Evidence supports the effectiveness of the framework in facilitating reflection and in linking reflection to higher order cognitive processes such as gaining new insights and understandings, facilitation of systematic enquiry, problem solving, and decision making. Feedback from students indicated that the experience was meaningful and valuable in preparation for practice because they were guided to question themselves and could see the relevance and value of that for their practice. We recommend that educators consider this approach to facilitating reflection in physiotherapy undergraduate education.

  7. Quantitative Literacy at Michigan State University, 1: Development and Initial Evaluation of the Assessment

    Directory of Open Access Journals (Sweden)

    Alla Sikorskii


    Full Text Available Development, psychometric testing, and the results of the administration of a quantitative literacy (QL assessment to undergraduate students are described. Three forms were developed covering a wide range of skills, contexts, and quantitative information presentation formats. Following item generation and revision based on preliminary testing and cognitive interviewing, a total of 3,701 consented undergraduate students at Michigan State University completed one of the three forms. Two of the forms contained 14 multiple-choice items, and one form contained 17 multiple-choice items. All forms were completed by students in less than 30 minutes. Evidence of validity and reliability were obtained for the three forms. Unidimensionality of the underlying construct was established using confirmatory factor analysis. Correlations with ACT and university mathematics placement test ranged from .41 to .67, and correlations with the Lipkus numeracy scale ranged from .40 to .45. Cronbach’s alphas for the three forms were near or exceeded .70. Comparison of student QL performance according to demographic characteristics revealed gender differences, with males scoring higher than females. These gender differences persisted even after controlling for ACT composite scores. Race/ethnicity differences were significant in unadjusted analysis, but did not persist over and above ACT composite scores in the adjusted analyses. The three newly developed forms of QL assessment will need to be further tested in the future to determine if they capture the effects of interventions that aim to improve QL.

  8. Multidisciplinary assessment of children with deficits relating to attention, motor activity and perception: evaluation of the ANSER model. (United States)

    Isberg, E; Kjellman, B


    This study describes a process for multidisciplinary assessment of children having deficits in attention, motor activity and perception (DAMP) with an evaluation of that process based on the opinions of parents, teachers and team members. The process named the 'ANSER model' consists of six steps (I to VI) conducted over a 2-month period and a follow-up 2 years later (step VII). Parents and teachers are fully involved early in the process and their participation is considered essential for a good result. Particular consideration is given to directly helping a child understand him/herself and become aware of his/her own difficulties. Strategies to overcome those difficulties are developed together with the child, the parents and the teacher. A specific aspect of the assessment is the aim to provide therapy through discussion of the questions, thoughts and feelings evoked during, and by the process. The expectations of parents and teachers regarding the assessment, and their completion of six steps of the process were ascertained from questionnaires. A large majority of both parents and teachers had high expectations of the assessment. Slightly more parents than teachers were convinced of its necessity. Their expectations were satisfied. Parents, teachers and team members emphasized the importance of the participation of parents and teachers in the process. The average time required for a complete assessment according to the process and including the work of all the specialists was 33 hours.

  9. The application of inertial measurements unit for the clinical evaluation and assessment of gait events. (United States)

    Sharif Bidabadi, Shiva; Murray, Iain; Lee, Gabriel Yin Foo


    Foot drop is one of the common gait abnormalities which are difficult to detect, diagnose and evaluate. While various gait monitoring systems are available, many are computationally expensive and difficult to implement outside laboratory environments. This study introduces an in-house designed system based on inertial measurement units to capture the gait symptoms, specifically in the case of foot drop symptoms. The system specification and communication results, as well as filtering methods are discussed. Also, the pitch angle of thigh, shank and foot from a subject with no reported foot problem have been compared (gathered from identical equipment under similar conditions) to the same angle from a foot drop subject.

  10. Assessing competencies: an evaluation of ASTD's Certified Professional in Learning and Performance (CPLP) designation. (United States)

    Kwon, Seolim; Wadholm, Robert R; Carmody, Laurie E


    The American Society of Training and Development's (ASTD) Certified Professional in Learning and Performance (CPLP) program is purported to be based on the ASTD's competency model, a model which outlines foundational competencies, roles, and areas of expertise in the field of training and performance improvement. This study seeks to uncover the relationship between the competency model and the CPLP knowledge exam questions and work product submissions (two of the major instruments used to test for competency of CPLP applicants). A mixed qualitative-quantitative approach is used to identify themes, quantify relationships, and assess questions and guidelines. Multiple raters independently analyzed the data and identified key themes, and Fleiss' Kappa coefficient was used in measuring inter-rater agreement. The study concludes that several discrepancies exist between the competency model and the knowledge exam and work product submission guidelines. Recommendations are given for possible improvement of the CPLP program. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Pittayapat, Pisha; Oliveira-Santos, Christiano; Thevissen, Patrick; Michielsen, Koen; Bergans, Niki; Willems, Guy; Debruyckere, Deborah; Jacobs, Reinhilde


    Recently developed portable dental X-ray units increase the mobility of the forensic odontologists and allow more efficient X-ray work in a disaster field, especially when used in combination with digital sensors. This type of machines might also have potential for application in remote areas, military and humanitarian missions, dental care of patients with mobility limitation, as well as imaging in operating rooms. To evaluate radiographic image quality acquired by three portable X-ray devices in combination with four image receptors and to evaluate their medical physics parameters. Images of five samples consisting of four teeth and one formalin-fixed mandible were acquired by one conventional wall-mounted X-ray unit, MinRay 60/70 kVp, used as a clinical standard, and three portable dental X-ray devices: AnyRay 60 kVp, Nomad 60 kVp and Rextar 70 kVp, in combination with a phosphor image plate (PSP), a CCD, or a CMOS sensor. Three observers evaluated images for standard image quality besides forensic diagnostic quality on a 4-point rating scale. Furthermore, all machines underwent tests for occupational as well as patient dosimetry. Statistical analysis showed good quality imaging for all system, with the combination of Nomad and PSP yielding the best score. A significant difference in image quality between the combination of the four X-ray devices and four sensors was established (p1m: Rextar <0.2 microGy, MinRay <0.1 microGy). The present study demonstrated the feasibility of three portable X-ray systems to be used for specific indications, based on acceptable image quality and sufficient accuracy of the machines and following the standard guidelines for radiation hygiene.

    Pandya J


    Full Text Available Background: Postgraduate specialities require a combination of knowledge and clinical skills. The internship year is less structured. Clinical and practical skills that are picked up during training are not well regulated and the impact is not assessed. In this study, we assessed knowledge and skills using objective structured clinical examination (OSCE. Aim: To evaluate the clinical skills of new first-year surgical residents using orientation programme and OSCE as a tool for assessment. Settings and Design: Observational study. Materials and Methods: Twenty new first-year surgical residents (10 each in 2008 and 2009 participated in a detailed structured orientation programme conducted over a period of 7 days. Clinically important topics and skills expected at this level (e.g., suturing, wound care etc. were covered. The programme was preceded by an OSCE to test pre-programme knowledge (the "pre-test". The questions were validated by senior department staff. A post-programme OSCE (the "post-test" helped to evaluate the change in clinical skill level brought about by the orientation programme. Statistical Analysis: Wilcoxson matched-pairs signed-ranks test. Results: Passing performance was achieved by all participants in both pre- and post-tests. Following the orientation programme, significant improvement was seen in tasks testing the psychomotor and cognitive domains. (P = 0.0001 and P = 0.0401, respectively. Overall reliability of the OSCE was found to be 0.7026 (Cronbach′s coefficient alpha. Conclusions: This study highlighted the lacunae in current internship training, especially for skill-based tasks. There is a need for universal inclusion of structured orientation programmes in the training of first-year residents. OSCE is a reliable, valid and effective method for the assessment of clinical skills.

  14. Evaluation of the assessment and documentation of chronic wounds in residential social care in the Czech Republic. (United States)

    Saibertová, S; Pokorná, A


    Accurate evaluation of non-healing, chronic wounds followed by the selection of an appropriate therapeutic strategy is a must for the foundation of health-care management. Assessment of non-healing chronic wounds in clinical practice in the Czech Republic is not standardised in acute care settings or in residential social care facilities. The aim of the study was to analyse the methods being used to assess non-healing, chronic wounds in residential social services in the Czech Republic, where more patients with chronic wounds are present because of the increasing incidence of wounds in old age. The research was carried out at 66 residential social care institutions across all regions of the Czech Republic. A mixed model was used for the research (participatory observation including creation of field notes and content analysis of documents for documentation and analysis of qualitative and quantitative data). The same methodology was used in previous work which has been done in acute care settings in 2013. The results of this research have corroborated the inconsistencies in procedures used by general nurses for assessment of non-healing, chronic wounds. However, the situation was found to be more positive with regard to the evaluation of basic/fundamental parameters of a wound (e.g. size, depth and location of the wound) compared with the evaluation of more specific parameters (e.g. exudate or signs of infection). This included not only the number of observed variables, but also the action taken. Both were improved when a consultant for wound healing was present. An effective strategy for wound management depends on the method and scope of the assessment of non-healing, chronic wounds in place in clinical practice in observed facilities; improvement may be expected following the general introduction of 'non-healing, chronic wound assessment' algorithm.

  16. A review of performance standards to monitor, evaluate and assess the impact of technology transfer offices

    Directory of Open Access Journals (Sweden)

    Sibongile Gumbi


    Full Text Available The conversion of scientific discoveries to new products and processes and their launch onto the market can be a lengthy process. Similarly, it takes many years before the impact of scientific research on society and the economy is realised and a further length of time before its performance can be measured. Higher education and research institutions, and their governments, often make significant investments into intellectual property management and technology transfer activities through legislative and policy development, human resource development, financial allocation and infrastructure improvement. Since returns on such investments are not immediately apparent, it is important to establish a means by which the impact of their efforts can be determined. In this paper, I examined the measures and indicators that could be developed by institutions and their stakeholders in order to monitor, evaluate and determine the impact of research output and outcomes on the market.

  17. Microbial biotransformation of furosemide for environmental risk assessment: identification of metabolites and toxicological evaluation. (United States)

    Olvera-Vargas, Hugo; Leroy, Sébastien; Rivard, Michael; Oturan, Nihal; Oturan, Mehmet; Buisson, Didier


    Some widely prescribed drugs are sparsely metabolized and end up in the environment. They can thus be a focal point of ecotoxicity, either themselves or their environmental transformation products. In this context, we present a study concerning furosemide, a diuretic, which is mainly excreted unchanged. We investigated its biotransformation by two environmental fungi, Aspergillus candidus and Cunninghamella echinulata. The assessment of its ecotoxicity and that of its metabolites was performed using the Microtox test (ISO 11348-3) with Vibrio fischeri marine bacteria. Three metabolites were identified by means of HPLC-MS and 1 H/ 13 C NMR analysis: saluamine, a known pyridinium derivative and a hydroxy-ketone product, the latter having not been previously described. This hydroxy-ketone metabolite was obtained with C. echinulata and was further slowly transformed into saluamine. The pyridinium derivative was obtained in low amount with both strains. Metabolites, excepting saluamine, exhibited higher toxicity than furosemide, being the pyridinium structure the one with the most elevated toxic levels (EC 50  = 34.40 ± 6.84 mg L -1 ). These results demonstrate that biotic environmental transformation products may present a higher environmental risk than the starting drug, hence highlighting the importance of boosting toxicological risk assessment related to the impact of pharmaceutical waste.

    Velusami, Chandrasekaran Chinampudur; Boddapati, Srinivasa Rao; Hongasandra Srinivasa, Srikanth; Richard, Edwin Jothie; Balasubramanian, Murali


    Curcuma longa Linn. (Zingiberaceae) commonly known as turmeric has long been used for centuries as a spice and household remedy. The present study was carried out to assess the possible mutagenic potential and acute oral toxicity of polysaccharide extract of turmeric rhizome (NR-INF-02) using standard tests. The standard battery of in vitro genotoxicity tests, bacterial reverse mutation test (BRMT), chromosome aberration (CA), and micronucleus (MN) tests were employed to assess the possible mutagenic activity of NR-INF-02 (Turmacin). The results showed no mutagenic effect with NR-INF-02 up to a dose of 5000 µg/mL in BRMT. The results on CA and MN tests revealed the non clastogenic activity of NR-INF-02 in a dose range of 250.36 to 2500 µg/mL with and without metabolic activation (S9). In acute oral toxicity study, NR-INF-02 was found to be safe up to 5 g/kg body weight in Wistar rats. Overall, results indicated that polysaccharide extract of C. longa was found to be genotoxically safe and also exhibited maximum tolerable dose of more than 5 g/kg rat body weight. PMID:24455673

  19. Attachment based treatments for adolescents: the secure cycle as a framework for assessment, treatment and evaluation. (United States)

    Kobak, Roger; Zajac, Kristyn; Herres, Joanna; Krauthamer Ewing, E Stephanie


    The emergence of attachment-based treatments (ABTs) for adolescents highlights the need to more clearly define and evaluate these treatments in the context of other attachment based treatments for young children and adults. We propose a general framework for defining and evaluating ABTs that describes the cyclical processes that are required to maintain a secure attachment bond. This secure cycle incorporates three components: (1) the child or adult's IWM of the caregiver; (2) emotionally attuned communication; and (3) the caregiver's IWM of the child or adult. We briefly review Bowlby, Ainsworth, and Main's contributions to defining the components of the secure cycle and discuss how this framework can be adapted for understanding the process of change in ABTs. For clinicians working with adolescents, our model can be used to identify how deviations from the secure cycle (attachment injuries, empathic failures and mistuned communication) contribute to family distress and psychopathology. The secure cycle also provides a way of describing the ABT elements that have been used to revise IWMs or improve emotionally attuned communication. For researchers, our model provides a guide for conceptualizing and measuring change in attachment constructs and how change in one component of the interpersonal cycle should generalize to other components.

  20. Development and preliminary evaluation of a music-based attention assessment for patients with traumatic brain injury. (United States)

    Jeong, Eunju; Lesiuk, Teresa L


    Impairments in attention are commonly seen in individuals with traumatic brain injury (TBI). While visual attention assessment measurements have been rigorously developed and frequently used in cognitive neurorehabilitation, there is a paucity of auditory attention assessment measurements for patients with TBI. The purpose of this study was to field test a researcher-developed Music-based Attention Assessment (MAA), a melodic contour identification test designed to assess three different types of attention (i.e., sustained attention, selective attention, and divided attention), for patients with TBI. Additionally, this study aimed to evaluate the readability and comprehensibility of the test items and to examine the preliminary psychometric properties of the scale and test items. Fifteen patients diagnosed with TBI completed 3 different series of tasks in which they were required to identify melodic contours. The resulting data showed that (a) test items in each of the 3 subtests were found to have an easy to moderate level of item difficulty and an acceptable to high level of item discrimination, and (b) the musical characteristics (i.e., contour, congruence, and pitch interference) were found to be associated with the level of item difficulty, and (c) the internal consistency of the MAA as computed by Cronbach's alpha was .95. Subsequent studies using a larger sample of typical participants, along with individuals with TBI, are needed to confirm construct validity and internal consistency of the MAA. In addition, the authors recommend examination of criterion validity of the MAA as correlated with current neuropsychological attention assessment measurements.

  1. Multi-criteria evaluation of hydro-geological and anthropogenic parameters for the groundwater vulnerability assessment. (United States)

    Kumar, Prashant; Thakur, Praveen K; Bansod, Baban Ks; Debnath, Sanjit K


    Groundwater contamination assessment is a challenging task due to inherent complex dynamisms associated with the groundwater. DRASTIC is a very widely used rapid regional tool for the assessment of vulnerability of groundwater to contamination. DRASTIC has many lacunas in the form of subjectivities associated with weights and ratings of its hydro-geological parameters, and, therefore, the accuracy of the DRASTIC-based vulnerability map is questioned. The present study demonstrates the optimisation of the DRASTIC parameters along with a scientific consideration to the anthropogenic factors causing groundwater contamination. The resulting scientific consistent weights and ratings to DRASTIC parameters assist in the development of a very precise groundwater vulnerability map highlighting different zones of different gravity of contamination. One of the most important aspects of this study is that we have considered the impact of vadose zone in a very comprehensive manner by considering every sub-surface layer from the earth surface to the occurrence of groundwater. The study area for our experiment is Fatehgarh Sahib district of Punjab which is facing several groundwater issues.

  2. Perioperative outcomes following surgery for brain tumors: Objective assessment and risk factor evaluation

    Directory of Open Access Journals (Sweden)

    Aliasgar V Moiyadi


    Full Text Available Background: Perioperative outcomes following surgery for brain tumors are an important indicator of the safety as well as efficacy of surgical intervention. Perioperative morbidity not only has implications on direct patient care, but also serves as an indicator of the quality of care provided, and enables objective documentation, for comparision in various clinical trials. We document our experience at a tertiary care referral, a dedicated neuro-oncology center in India. Materials and Methods: One hundred and ninety-six patients undergoing various surgeries for intra-axial brain tumors were analyzed. Routine microsurgical techniques and uniform antibiotic policy were used. Navigation/ intraoperative electrophysiological monitoring was not available. The endpoints assessed included immediate postoperative neurological status, neurological outcome at discharge, regional complications, systemic complications, overall morbidity, and mortality. Various risk factors assessed included clinico-epidemiological factors, tumor-related factors, and surgery-related factors. Univariate and multivariate analysis were performed. Results: Median age was 38 years. 72% had tumors larger than 4 cm. Neurological morbidity, and regional and systemic complications occurred in 16.8, 17.3, and 10.7%, respectively. Overall, major morbidity occurred in 18% and perioperative mortality rate was 3.6%. Although a few of the known risk factors were found to be significant on univariate analysis, none achieved significance on multivariate analysis. Conclusions: Our patients were younger and had larger tumors than are generally reported. Despite the unavailability of advanced intraoperative aids we could achieve acceptable levels of morbidity and mortality. Objective recording of perioperative events is crucial to document outcomes after surgery for brain tumors.

This document describes ISV technology that is available as another viable tool for in place stabilization of waste sites. The following sections correspond to the chapters in the body of this document: description of the ISV process; analysis of the performane of the ISV tests conducted thus far; parameters of the ISV process; cost analysis for the ISV process; analysis of occupational and public exposure; and assessment of waste site applications.

  4. Acceptability and feasibility of mini-clinical evaluation exercise as a formative assessment tool for workplace-based assessment for surgical postgraduate students

    Directory of Open Access Journals (Sweden)

    M K Joshi


    Full Text Available Background: Despite an increasing emphasis on workplace-based assessment (WPBA during medical training, the existing assessment system largely relies on summative assessment while formative assessment is less valued. Various tools have been described for WPBA, mini-clinical evaluation exercise (mini-CEX being one of them. Mini-CEX is well accepted in Western countries, however, reports of its use in India are scarce. We conducted this study to assess acceptability and feasibility of mini-CEX as a formative assessment tool for WPBA of surgical postgraduate students in an Indian setting. Methods: Faculty members and 2nd year surgical residents were sensitized toward mini-CEX and requisite numbers of exercises were conducted. The difficulties during conduction of these exercises were identified, recorded, and appropriate measures were taken to address them. At the conclusion, the opinion of residents and faculty members regarding their experience with mini-CEX was taken using a questionnaire. The results were analyzed using simple statistical tools. Results: Nine faculty members out of 11 approached participated in the study (81.8%. All 16 2nd year postgraduate surgical residents participated (100%. Sixty mini-CEX were conducted over 7 months. Each resident underwent 3–5 encounters. The mean time taken by the assessor for observation was 12.3 min (8–30 min while the mean feedback time was 4.2 min (3–10 min. The faculty reported good overall satisfaction with mini-CEX and found it acceptable as a formative assessment tool. Three faculty members (33.3% reported mini-CEX as more time-consuming while 2 (22.2% found it difficult to carry the exercises often. All residents accepted mini-CEX and most of them reported good to high satisfaction with the exercises conducted. Conclusions: Mini-CEX is well accepted by residents and faculty as a formative assessment tool. It is feasible to utilize mini-CEX for WPBA of postgraduate students of surgery.

  5. Assessing DRAGON Measurements for Evaluation and Assimilation in the GEOS-5 Aerosol Forecasting System (United States)

    da Silva, A.; Colarco, P. R.; Darmenov, A.; Holben, B. N.


    GEOS-5 is the latest version of the NASA Global Modeling and Assimilation Office (GMAO) earth system model. GEOS-5 contains components for atmospheric circulation and composition (including data assimilation), ocean circulation and biogeochemistry, and land surface processes. In addition to traditional meteorological parameters, GEOS-5 includes modules representing the atmospheric composition, most notably aerosols and tropospheric/stratospheric chemical constituents, taking explicit account of the impact of these constituents on the radiative processes of the atmosphere. The assimilation of Aerosol Optical Depth (AOD) in GEOS-5 involves very careful cloud screening and homogenization of the observing system by means of a Neural Net scheme that translates MODIS radiances into AERONET calibrated AOD. These measurements are further quality controlled using an adaptive buddy check scheme, and assimilated using the Local Displacement Ensemble (LDE) methodology. The near real-time GEOS-5 aerosol forecasting system runs at a nominal 25km horizontal resolution with 72 vertical layers (top at ~85km). GEOS-5 is driven by daily biomass burning emissions derived from MODIS fire radiative power retrievals. In this talk we will utilize aerosol measurements from the Distributed Regional Aerosol Gridded Observation Networks (DRAGON) to evaluate the temporal and spatial distribution of aerosols in GEOS-5. While NRT assimilation of MODIS optical depth observations constrains the GEOS-5 aerosol distributions during satellite overpasses, the diurnal cycle, mixing state and optical properties are internally determined by the model parameterizations and require careful validation. By combining DRAGON with other in-situ and remotely sensed measurements from the DISCOVER-AQ and SEAC4RS field campaigns we will present a comprehensive evaluation of the GEOS-5 aerosol state, and examine the impact of assimilating the DRAGON measurements on the quality of the GEOS-5 analysis and forecasts

  6. Evaluating risks to wildlife from coal fly ash incorporating recent advances in metals and metalloids risk assessment. (United States)

    Meyer, Carolyn B; Schlekat, Tamar H; Walls, Suzanne J; Iannuzzi, Jacqueline; Souza, Marcy J


    Current scientific advances in metal and metalloid risk assessment were applied to evaluate risk to aquatic and riparian wildlife species potentially impacted by residual coal fly ash after cleanup of an unprecedented large ash release into an aquatic environment-the first assessment of its kind. Risk was evaluated using multiple lines of evidence (LOE), including 1) tissue-based risk assessment of inorganic concentrations in piscivorous and insectivorous bird eggs and raccoon organs, 2) deterministic and probabilistic diet-based risk estimates for 10 receptors species, 3) raccoon health metrics, and 4) tree swallow nest productivity measures. Innovative approaches included use of tissue-based toxicity reference values (TRVs), adjustment of bioavailability in the dietary uptake models (using sequential metal extractions in sediment), partitioning chemical species into uptake compartments (e.g., prey gut, nongut, sediment), incorporating uncertainty in both modeled dose and dietary TRVs, matching TRVs to chemical forms of constituents, and pairing these LOEs with reproductive success or health status of sensitive receptor species. The weight of evidence revealed that risk to wildlife from residual ash was low and that risk, though low, was most pronounced for insectivorous birds from exposure to Se and As. This information contributes to the debate surrounding coal combustion residue regulations prompted by this ash release. Because of the responsible party's proactive approach of applying state-of-the-art methods to assess risk using several LOEs that produced consistent results, and because of their inclusion of the regulating agencies in decisions at every step of the process, the risk assessment results were accepted, and an effective approach toward cleanup protective of the environment was quickly implemented. This study highlights the value of using multiple LOEs and the latest scientific advances to assist in timely decision making to obtain an effective

  7. Assessing the differences between numerical methods and real experiments for the evaluation of reach envelopes of the human body

    CERN Document Server

    Delangle, Mathieu; Poirson, Emilie


    The use of static human body dimensions to assess the human accessibility is an essential part of an ergonomic approach in user-centered design. Assessments of reach capability are commonly performed by exercising external anthropometry of human body parts, which may be found in anthropometric databases, to numerically define the reach area of an intended user population. The result is a reach envelope determined entirely by the segment lengths, without taking into account external variables, as the nature of the task or the physical capacities of the subject, which may influence the results. Considering the body as a simple assembly of static parts of different anthropometry is limiting. In this paper, the limit of validity of this approach is assessed by comparing the reach envelopes obtained by this method to those obtained with a simple two-dimensional experimental reaching task of a panel of subjects. Forty subjects experimentally evaluated the reach, first with the body constrained and second unconstrai...

  11. An evaluation of in-house and off-the-shelf in silico models: implications on guidance for mutagenicity assessment. (United States)

    Jolly, Robert; Ahmed, Kausar Begam Riaz; Zwickl, Craig; Watson, Ian; Gombar, Vijay


    The evaluation of impurities for genotoxicity using in silico models are commonplace and have become accepted by regulatory agencies. Recently, the ICH M7 Step 4 guidance was published and requires two complementary models for genotoxicity assessments. Over the last ten years, many companies have developed their own internal genotoxicity models built using both public and in-house chemical structures and bacterial mutagenicity data. However, the proprietary nature of internal structures prevents sharing of data and the full OECD compliance of such models. This analysis investigated whether using in-house internal compounds for training models is needed and substantially impacts the results of in silico genotoxicity assessments, or whether using commercial-off-the-shelf (COTS) packages such as Derek Nexus or Leadscope provide adequate performance. We demonstrated that supplementation of COTS packages with a Support Vector Machine (SVM) QSAR model trained on combined in-house and public data does, in fact, improve coverage and accuracy, and reduces the number of compounds needing experimental assessment, i.e., the liability load. This result indicates that there is added value in models trained on both internal and public structures and incorporating such models as part of a consensus approach improves the overall evaluation. Lastly, we optimized an in silico consensus decision-making approach utilizing two COTS models and an internal (SVM) model to minimize false negatives. Copyright © 2015 Elsevier Inc.

  12. Assessing the Straightforwardly-Worded Brief Fear of Negative Evaluation Scale for Differential Item Functioning Across Gender and Ethnicity. (United States)

    Harpole, Jared K; Levinson, Cheri A; Woods, Carol M; Rodebaugh, Thomas L; Weeks, Justin W; Brown, Patrick J; Heimberg, Richard G; Menatti, Andrew R; Blanco, Carlos; Schneier, Franklin; Liebowitz, Michael


    The Brief Fear of Negative Evaluation Scale (BFNE; Leary Personality and Social Psychology Bulletin , 9, 371-375, 1983) assesses fear and worry about receiving negative evaluation from others. Rodebaugh et al. Psychological Assessment, 16 , 169-181, (2004) found that the BFNE is composed of a reverse-worded factor (BFNE-R) and straightforwardly-worded factor (BFNE-S). Further, they found the BFNE-S to have better psychometric properties and provide more information than the BFNE-R. Currently there is a lack of research regarding the measurement invariance of the BFNE-S across gender and ethnicity with respect to item thresholds. The present study uses item response theory (IRT) to test the BFNE-S for differential item functioning (DIF) related to gender and ethnicity (White, Asian, and Black). Six data sets consisting of clinical, community, and undergraduate participants were utilized ( N =2,109). The factor structure of the BFNE-S was confirmed using categorical confirmatory factor analysis, IRT model assumptions were tested, and the BFNE-S was evaluated for DIF. Item nine demonstrated significant non-uniform DIF between White and Black participants. No other items showed significant uniform or non-uniform DIF across gender or ethnicity. Results suggest the BFNE-S can be used reliably with men and women and Asian and White participants. More research is needed to understand the implications of using the BFNE-S with Black participants.

  13. Application of food and feed safety assessment principles to evaluate transgenic approaches to gene modulation in crops. (United States)

    Parrott, Wayne; Chassy, Bruce; Ligon, Jim; Meyer, Linda; Petrick, Jay; Zhou, Junguo; Herman, Rod; Delaney, Bryan; Levine, Marci


    New crop varieties containing traits such as enhanced nutritional profiles, increased yield, and tolerance to drought are being developed. In some cases, these new traits are dependent on small RNAs or regulatory proteins such as transcription factors (TF) that modify the expression of endogenous plant genes. To date, the food and feed safety of genetically modified (GM) crops has been assessed by the application of a set of internationally accepted procedures for evaluating the safety of GM crops. The goal of this paper is to review the main aspects of the current safety assessment paradigm and to recommend scientifically sound principles for conducting a safety assessment for GM crops that are developed by technologies that modify endogenous plant gene expression. Key considerations for such a safety assessment include the following: (1) RNA and TF are generally recognized as safe (GRAS); (2) Genes encoding RNAi and regulatory proteins such as TFs are an important component of the plantgenome; (3) Crops engineered using RNAi modifications are not expected to produce heterologous proteins; (4) The modulation of TFs may result in quantitative differences in endogenous plant components,which can be assessed through agronomic performance and compositional analysis on a caseby-case basis. 2010 ILSI.

    Shastak, Y; Witzig, M; Hartung, K; Bessei, W; Rodehutscord, M


    The main objective of this study was to compare different bone measurements in response to supplements of mineral P sources. Comparisons were also made with P retention and digestibility responses determined in a companion study and with blood inorganic phosphate (P(i)) responses. A corn-soybean meal-based basal diet was used (0.35% total P on DM basis). Anhydrous monosodium phosphate (MSP(a)) or anhydrous dibasic calcium phosphate (DCP(a)) was supplemented to increment the P concentration by 0.08%, 0.16%, or 0.24%. Each of the 7 diets was fed for 10 d starting 11 d (period 1) or 25 d posthatch (period 2). Bone ash and P were determined, and density criteria were measured using quantitative computed tomography. Responses were evaluated and compared based on linear regression analysis. In general, responses to MSP(a) had a greater slope than DCP(a) for all criteria studied. In period 1, differences between the slopes were significant (P bone criteria. In period 2, the slopes significantly differed for the amounts of ash and P of all bones studied, for tibia, tarsometatarus, and foot ash percentage, for total and cortical density of tibiae, but not for the other criteria. For the different bones, the ratio of slopes for MSP(a) and DCP(a) was very similar based on the amount of ash in both periods. Foot ash proved to be as sensitive as tibia ash for evaluation of mineral P sources in both periods. Ninety-four percent of the variance of the corticalis content based on quantitative computed tomography measurements could be explained by the amount of tibia ash in period 1. Blood serum P(i) and BW gain were not suitable for P evaluation. We concluded that the ranking of mineral P sources based on bone criteria differed from the ranking that was based on P retention or prececal digestibility. This underlines the need for developing a standard protocol of determination of available P in poultry.

    The Mini-Clinical Evaluation Exercise (mini-CEX) is one of the most commonly used clinical assessment tools to provide learner feedback to drive learning. High quality constructive feedback promotes development and improves clinical competency. However, the effectiveness of feedback has not been objectively evaluated from the learners' and assessors' points of view, especially in Asia, where the nature of the student-tutor relationship is relatively hierarchical. This study seeks to compare the strengths, limitations, and feedback of the mini-CEX between assessors and students. A cross-sectional study was conducted among 275 senior medical undergraduates at the National University of Singapore and 121 clinical tutors from seven restructured hospitals in Singapore. Data was collected via a self-administered questionnaire. Univariate analysis was used to determine the prevalence of responses, as well as differences between tutors and students. The mini-CEX provided immediate feedback and timely correction of mistakes. However, effective administration was limited by inter-tutor variability and lack of time. Students reported being receptive to feedback, but tutors disagreed and felt that students were resistant to negative feedback. Additionally, students felt that their performance was compared unfairly against more senior students, although the tutors felt otherwise. The mini-CEX is an effective assessment tool, but is limited by barriers to administration and evaluation. Differing opinions and expectations between tutors and students could provide an interesting focal point for future studies.

  17. Ultrasound assessment of selected peripheral nerve pathologies. Part III: Injuries and postoperative evaluation

    Directory of Open Access Journals (Sweden)

    Berta Kowalska


    Full Text Available The previous articles of the series devoted to ultrasound diagnostics of peripheral nerves concerned the most common nerve pathologies, i.e. entrapment neuropathies. The aim of the last part of the series is to present ultrasound possibilities in the postoperative control of the peripheral nerves as well as in the diagnostics of the second most common neuropathies of peripheral nerves, i.e. posttraumatic lesions. Early diagnostics of posttraumatic changes is of fundamental importance for the course of treatment and its long-term effects. It aids surgeons in making treatment decisions (whether surgical or conservative. When surgical treatment is necessary, the surgeon, based on US findings, is able to plan a given type of operative method. In certain cases, may even abandon the corrective or reconstructive surgery of the nerve trunk (when there are extensive defects of the nerve trunks and instead, proceed with muscle transfers. Medical literature proposes a range of divisions of the kinds of peripheral nerve injuries depending on, among others, the mechanism or degree of damage. However, the most important issue in the surgeon-diagnostician communication is a detailed description of stumps of the nerve trunks, their distance and location. In the postoperative period, ultrasound is used for monitoring the operative or conservative treatment effects including the determination of the causes of a persistent or recurrent neuropathy. It facilitates decision-making concerning a repeated surgical procedure or assuming a wait-and-see attitude. It is a difficult task for a diagnostician and it requires experience, close cooperation with a clinician and knowledge concerning surgical techniques. Apart from a static assessment, a dynamic assessment of possible adhesions constitutes a crucial element of postoperative examination. This feature distinguishes ultrasound scanning from other methods used in the diagnostics of peripheral neuropathies.

    Pottier, P; Cohen Aubart, F; Steichen, O; Desprets, M; Pha, M; Espitia, A; Georgin-Lavialle, S; Morel, A; Hardouin, J B


    The revision of the French medical studies' third cycle ought to be competency-based. In internal medicine, theoretical and practical knowledge will be assessed online with e-learning and e-portfolio. In parallel, a reflection about clinical skills assessment forms is currently ongoing. In this context, our aim was to assess the reproducibility and validity of two assessment forms based on direct clinical observation. A prospective and multicentric study has been conducted from November 2015 to October 2016 aiming at evaluating the French translations of the MINI-Clinical Examination Exercice (MINI-CEX) and the Standardized Patient Satisfaction Questionnaire (SPSQ). Included residents have been assessed 2 times over a period of 6 months by the same binoma of judges. Nineteen residents have been included. The inter-judge reproducibility was satisfactory for the MINI-CEX: intraclass coefficients (ICC) between 0.4 and 0.8 and moderate for the SPSQ: ICC between 0.2 and 0.7 with a good internal coherence for both questionnaires (Cronbach between 0.92 and 0.94). Significant differences between the distributions of the scores given by the judges and a significant inter-center variability have been found. If the absolute value of the scores should not be taken into account in the evaluation process given its high variability, it could be of interest for the follow-up of the progression in the competencies. These forms could support the residents' debriefing based on the general trends given by the scores. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

  19. Evaluation of bone mechanical strenght and fracture risk assessment (Frax) in patients with hip joint replacement surgery. (United States)

    Rodrigues, A; Caetano-Lopes, J; Nery, A; Sousa, E; Polido-Pereira, J; Vale, M; Amaral, P; Romeu, J C; Viana Queiroz, M; Monteiro, J; Vaz, M F; Fonseca, J E; Canhão, H


    Fracture risk assessment tools are useful to calculate the long term probability of osteoporotic fracture. However, how it reflects bone quality is unknown. The aim of this study was to correlate the WHO clinical fracture risk assessment tool, FRAX, with bone mechanical properties. Six patients submitted to hip replacement surgery, either due to osteoporotic fractures or to osteoarthritis, were evaluated. Bone samples were collected and the mechanical properties assessed by compression tests. Patients' data regarding the presence of clinical risk factors for fracture were registered. Laboratorial assessment of bone metabolic parameters and a dual X-ray absorptiometry(DXA) were done. Analysis of the load-displacement curves showed that patients with fragility fractures (n=4) had low values of elastic modulus, yield load and energy absorbed until yield point. Osteoarthritis patients tend to have a better biomechanical performance.Femoral neck DXA scan was also performed in 3 patients. Fragility fracture patients had a lower bone mineral density than the patients with osteoarthritis. FRAX algorithm was applied and a positive relation was found between FRAX results and biomechanical parameters. Blood bone metabolic markers were within the normal range for all the subjects. The worse mechanical properties observed in the fragility fracture patients were related to high probability of fracture given by FRAX. These observations, in a very small sample, need further confirmation. However, they suggest that the fracture risk assessment tool, FRAX, may reflect the current mechanical bone behavior of the patient.

  1. Using Unmanned Aerial Vehicles to Assess Vegetative Cover and Identify Biotic Resources in Sagebrush Steppe Ecosystems: Preliminary Evaluation

    Energy Technology Data Exchange (ETDEWEB)

    Robert P. Breckenridge


    The Idaho National Laboratory (INL), in conjunction with the University of Idaho, is evaluating novel approaches for using unmanned aerial vehicles (UAVs) as a quicker and safer method for monitoring biotic resources. Evaluating vegetative cover is an important factor in understanding the sustainability of many ecosystems. In assessing vegetative cover, methods that improve accuracy and cost efficiency could revolutionize how biotic resources are monitored on western federal lands. Sagebrush steppe ecosystems provide important habitat for a variety of species, some of which are important indicator species (e.g., sage grouse). Improved methods are needed to support monitoring these habitats because there are not enough resource specialists or funds available for comprehensive ground evaluation of these ecosystems. In this project, two types of UAV platforms (fixed wing and helicopter) were used to collect still-frame imagery to assess cover in sagebrush steppe ecosystems. This paper discusses the process for collecting and analyzing imagery from the UAVs to (1) estimate total percent cover, (2) estimate percent cover for six different types of vegetation, and (3) locate sage grouse based on representative decoys. The field plots were located on the INL site west of Idaho Falls, Idaho, in areas with varying amounts and types of vegetative cover. A software program called SamplePoint developed by the U.S. Department of Agriculture, Agricultural Research Service was used to evaluate the imagery for percent cover for the six vegetation types (bare ground, litter, shrubs, dead shrubs, grasses, and forbs). Results were compared against standard field measurements to assess accuracy.

  2. A systematic assessment of MHC class II peptide binding predictions and evaluation of a consensus approach.

    Directory of Open Access Journals (Sweden)

    Peng Wang


    Full Text Available The identification of MHC class II restricted peptide epitopes is an important goal in immunological research. A number of computational tools have been developed for this purpose, but there is a lack of large-scale systematic evaluation of their performance. Herein, we used a comprehensive dataset consisting of more than 10,000 previously unpublished MHC-peptide binding affinities, 29 peptide/MHC crystal structures, and 664 peptides experimentally tested for CD4+ T cell responses to systematically evaluate the performances of publicly available MHC class II binding prediction tools. While in selected instances the best tools were associated with AUC values up to 0.86, in general, class II predictions did not perform as well as historically noted for class I predictions. It appears that the ability of MHC class II molecules to bind variable length peptides, which requires the correct assignment of peptide binding cores, is a critical factor limiting the performance of existing prediction tools. To improve performance, we implemented a consensus prediction approach that combines methods with top performances. We show that this consensus approach achieved best overall performance. Finally, we make the large datasets used publicly available as a benchmark to facilitate further development of MHC class II binding peptide prediction methods.

  3. Performance of different assessment methods to evaluate contaminant sources and fate in a coastal aquifer. (United States)

    Sbarbati, C; Colombani, N; Mastrocicco, M; Aravena, R; Petitta, M


    The present study deals with the application of different monitoring techniques and numerical models to characterize coastal aquifers affected by multiple sources of contamination. Specifically, equivalent freshwater heads in 243 monitoring wells were used to reconstruct the piezometric map of the studied aquifer; flow meter tests were carried out to infer vertical groundwater fluxes at selected wells; deuterium and oxygen isotopes were used to identify the groundwater origin, and tritium was analyzed to estimate the residence time; compound-specific isotope analyses and microbial analyses were employed to track different sources of contamination and their degradation; numerical modelling was used to estimate and verify groundwater flow direction and magnitude throughout the aquifer. The comparison of the information level for each technique allowed determining which of the applied approaches showed the best results to locate the possible sources and better understanding of the fate of the contaminants. This study reports a detailed site characterization process and outcomes for a coastal industrial site, where a comprehensive conceptual model of pollution and seawater intrusion has been built using different assessment methods. Information and results from this study encourages combining different methods for the design and implementation of the monitoring activities in real-life coastal contaminated sites in order to develop an appropriate strategy for control and remediation of the contamination.

  4. Assessment of body fatness in childhood obesity: evaluation of laboratory and anthropometric techniques

    Bandini, L.G.; Dietz, W.H. Jr.


    The identification of obesity as a pathological diagnosis depends on an accurate assessment of body fatness and a correlation of fatness with pathological consequences. Because total body fat varies with body weight, the proportion of body weight that is fat is probably a more reliable indicator of risk. Among obese children and adolescents, several problems have hindered the development of accurate clinical measures of percent body fat and total body fat. First, the use of direct methods to measure body composition is limited by expense and labor. Second, the relationship between anthropometric indexes and body composition in obese children and adolescents has not been intensively studied. Third, sample sizes of normal weight children have been too small to permit the development of diagnostic criteria. Fourth, the triceps skinfold is less reproducible in overweight subjects. Increases in lean body mass in obese adolescents may confound the use of the body mass index as a measure of adiposity. Current laboratory methods for the measurement of body composition include: (1) underwater weighing, (2) 40K counting, (3) isotopic dilution measures, (4) neutron activation, and (5) electrical impedance. This article examines relationships between those methods and anthropometry in the measurement of fatness in children and adolescents, as well as the difficulties in measuring body fatness and the importance of body fat distribution and its relationship to morbidity in children. Current evidence suggests an association of morbidity and upper segment obesity in adults. Corresponding studies in children and adolescents are yet to be carried out.

  5. Climate-physiographically differentiated Pan-European landslide susceptibility assessment using spatial multi-criteria evaluation and transnational landslide information (United States)

    Günther, Andreas; Van Den Eeckhaut, Miet; Malet, Jean-Philippe; Reichenbach, Paola; Hervás, Javier


    With the adoption of the EU Thematic Strategy for Soil Protection in 2006, small-scale (1:1 M) assessments of threats affecting soils over Europe received increasing attention. As landslides have been recognized as one of eight threats requiring a Pan-European evaluation, we present an approach for landslide susceptibility evaluation at the continental scale over Europe. Unlike previous continental and global scale landslide susceptibility studies not utilizing spatial information on the events, we collected more than 102,000 landslide locations in 22 European countries. These landslides are heterogeneously distributed over Europe, but are indispensable for the evaluation and classification of Pan-European datasets used as spatial predictors, and the validation of the resulting assessments. For the analysis we subdivided the European territory into seven different climate-physiographical zones by combining morphometric and climatic data for terrain differentiation, and adding a coastal zone defined as a 1 km strip inland from the coastline. Landslide susceptibility modeling was performed for each zone using heuristic spatial multicriteria evaluations supported by analytical hierarchy processes, and validated with the inventory data using the receiver operating characteristics. In contrast to purely data-driven statistical modeling techniques, our semi-quantitative approach is capable to introduce expert knowledge into the analysis, which is indispensable considering quality and resolution of the input data, and incompleteness and bias in the inventory information. The reliability of the resulting susceptibility map ELSUS 1000 Version 1 (1 km resolution) was examined on an administrative terrain unit level in areas with landslide information and through the comparison with available national susceptibility zonations. These evaluations suggest that although the ELSUS 1000 is capable for a correct synoptic prediction of landslide susceptibility in the majority of the

  6. Efficiency and effectiveness evaluation of three glass fiber post removal techniques using dental structure wear assessment method. (United States)

    Abe, Flávia Casale; Bueno, Carlos Eduardo da Silveira; De Martin, Alexandre Sigrist; Davini, Felipe; Cunha, Rodrigo Sanches


    This study evaluated the efficiency and effectiveness of three glass fiber post removal techniques. Forty-five extracted maxillary teeth were endodontically treated and cross-sectioned in thirds. Presence of cementing agent and dental structure wear were assessed by analyzing images taken before luting of glass fiber post and after removal procedure. Teeth were divided into 3 groups: Group 1 - diamond bur + Largo reamer; Group 2 - ultrasonic insert; Group 3 - carbide bur + ultrasonic insert. Time spent on removal procedures, dental structure wear and amount of remaining cement agent were recorded and results submitted to ANOVA, Kruskal Wallis and Tukey-Kramer tests. Group 1 - 16'46", 33.33% and 6.99%; Group 2 - 12'31", 40% and 7.86%; and Group 3 - 10'24", 80% and 8.14%. Group 3 presented the most effective removal of glass fiber posts. There was no significant difference in efficiency among the evaluated techniques.

  7. Visually impaired drivers who use bioptic telescopes: self-assessed driving skills and agreement with on-road driving evaluation. (United States)

    Owsley, Cynthia; McGwin, Gerald; Elgin, Jennifer; Wood, Joanne M


    To compare self-assessed driving habits and skills of licensed drivers with central visual loss who use bioptic telescopes to those of age-matched normally sighted drivers, and to examine the association between bioptic drivers' impressions of the quality of their driving and ratings by a "backseat" evaluator. Participants were licensed bioptic drivers (n = 23) and age-matched normally sighted drivers (n = 23). A questionnaire was administered addressing driving difficulty, space, quality, exposure, and, for bioptic drivers, whether the telescope was helpful in on-road situations. Visual acuity and contrast sensitivity were assessed. Information on ocular diagnosis, telescope characteristics, and bioptic driving experience was collected from the medical record or in interview. On-road driving performance in regular traffic conditions was rated independently by two evaluators. Like normally sighted drivers, bioptic drivers reported no or little difficulty in many driving situations (e.g., left turns, rush hour), but reported more difficulty under poor visibility conditions and in unfamiliar areas (P evaluators' ratings. Bioptic drivers show insight into the overall quality of their driving and areas in which they experience driving difficulty. They report using the bioptic telescope while driving, contrary to previous claims that it is primarily used to pass the vision screening test at licensure.
