    The purpose of this study was to estimate and examine ways to improve the reliability of change scores on the Alzheimer's Disease Assessment Scale, Cognitive Subtest (ADAS-Cog). The sample, provided by the Alzheimer's Disease Neuroimaging Initiative, included individuals with Alzheimer's disease (AD) (n = 153) and individuals with mild cognitive impairment (MCI) (n = 352). All participants were administered the ADAS-Cog at baseline and 1 year, and change scores were calculated as the difference in scores over the 1-year period. Three types of change score reliabilities were estimated using multivariate generalizability. Two methods to increase change score reliability were evaluated: reweighting the subtests of the scale and adding more subtests. Reliability of ADAS-Cog change scores over 1 year was low for both the AD sample (ranging from .53 to .64) and the MCI sample (.39 to .61). Reweighting the change scores from the AD sample improved reliability (.68 to .76), but lengthening provided no useful improvement for either sample. The MCI change scores had low reliability, even with reweighting and adding additional subtests. The ADAS-Cog scores had low reliability for measuring change. Researchers using the ADAS-Cog should estimate and report reliability for their use of the change scores. The ADAS-Cog change scores are not recommended for assessment of meaningful clinical change.

    1976-09-01

    In September 1974 candidates who had taken a computerized patient managment problem examination (CPMP), as part of the certification process in paediatrics required by the Royal College of Physicians and Surgeons of Canada, completed a questionnaire designed to elicit their reactions to CPMPs. The results indicated that respondents were favourable to CPMPs, that there was little distraction caused by the equipment, logic or semantics of the problems, and that CPMPs were an acceptable examination technique. It was recommended that, in the future, CPMP examinees be allowed practice time to familiarize themselves with the equipment, that pre-examination instructions should be clarified, and that problems judged inadequate by candidates be revised.

    Full Text Available Purpose: It aims to identify the effect of five variables to score of the Korean Medical Licensing Examinations (KMLE for three consecutive years from 2011 to 2013. Methods: The number of examinees for each examination was 3,364 in 2011 3,177 in 2012, and 3,287 in 2013. Five characteristics of examinees were set as variables: gender, age, graduation status, written test result (pass or fail, and city of medical school. A regression model was established, with the score of a written test as a dependent variable and with examinees’ traits as variables. Results: The regression coefficients in all variables, except the city of medical school, were statistically significant. The variable’s effect in three examinations appeared in the following order: result of written test, graduation status, age, gender, and city of medical school. Conclusion: written test scores of the KMLE revealed that female students, younger examinees, and first-time examinees had higher performances.

  16. An action research study on the effect of an examination preparation course on Veterinary Technology National Examination scores

    Limon, Jennifer S.

    The action research project used for this dissertation was intended to examine the effect of implementing an examination preparation course for graduates taking the Veterinary Technology National Examination in Louisiana. Previous data showed that scores on the VTNE were declining at not only the state, but also the national level, thus allowing less graduates to enter the workforce as Registered Veterinary Technicians in Louisiana. The research question was "What impact did the exam prep course have on VTNE test scores?" The researcher focused on helping to better prepare graduates from a local community college Veterinary Technology program to take the VTNE by implementing an exam review course in the semester prior to graduation from the program. The focus of the review course was not only content review, but also test taking techniques, help with study habits, as well as presentation of techniques to help deal with test anxiety. Three sources of data were collected by the researcher including pre and post intervention VTNE scores, as well as survey results completed by the graduates participating in the study. There were 13 graduates who participated in the study, and the data for 50 prior graduates was used as a comparison for score improvement. Upon completion of the intervention, Analysis of Variance (ANOVA) tests were used to analyze the data. The results revealed that while the intervention did have a positive effect on the graduates in terms of feeling prepared for the exam, it did not improve VTNE scores. A survey was administered to the participants upon completion of the course, and thematic coding was used to analyze the qualitative data. Overall the results indicated the learners felt the course helped prepare them for the VTNE, and the majority recommended implementing it for future learners.

  17. Impact of Online Learning Modules on Medical Student Microbiology Examination Scores

    2009-12-01

    Full Text Available Medical students have a limited amount of time in which to acquire working knowledge of an enormous amount of information, and this is especially relevant for microbiology. One large midwestern medical school is unique in having medical microbiology taught at nine regional campuses using a single core curriculum. A committee of statewide course directors writes a licensure board-style final examination that is referenced to the core and used at all campuses. To prepare for the final examination, students traditionally utilize print-based board examination review books. The purpose of the present study was to determine whether students who train using web-based quizzes score differently as a group on this statewide examination than students who do not utilize the materials online for exam preparation. The study included 71 learners from two different campuses who were taught by the same instructor and were admitted to medical school with similar exemplary credentials. Results were aggregated for three consecutive years. A standard medical microbiology textbook was used to assign the same suggested readings for all students and similar laboratory sessions were provided for all learners. The independent variable was use of the web-based quizzes to prepare before examinations, as indicated by student web usage logs. The dependent variable was score on the statewide final examination. Results support the hypothesis that students who use preparation modules online score higher on the final examination than students who do not. Moreover, students who prepared online scored higher on questions designed to test synthesis of knowledge and analysis of data. The significant difference in final examination outcome (P < 0.002 using a two-tailed unpaired t test indicates that online preparation for high-stakes examinations could improve student performance in medical microbiology.

    2016-01-01

    Background To determine whether the pre-medical Grade Point Average (GPA), Medical College Admission Test (MCAT), Internal examinations (Block) and National Board of Medical Examiners (NBME) scores are correlated with and predict the Medical Council of Canada Qualifying Examination Part I (MCCQE-1) scores. Methods Data from 392 admitted students in the graduating classes of 2010–2013 at University of Manitoba (UofM), College of Medicine was considered. Pearson’s correlation to assess the strength of the relationship, multiple linear regression to estimate MCCQE-1 score and stepwise linear regression to investigate the amount of variance were employed. Results Complete data from 367 (94%) students were studied. The MCCQE-1 had a moderate-to-large positive correlation with NBME scores and Block scores but a low correlation with GPA and MCAT scores. The multiple linear regression model gives a good estimate of the MCCQE-1 (R2 =0.604). Stepwise regression analysis demonstrated that 59.2% of the variation in the MCCQE-1 was accounted for by the NBME, but only 1.9% by the Block exams, and negligible variation came from the GPA and the MCAT. Conclusions Amongst all the examinations used at UofM, the NBME is most closely correlated with MCCQE-1. PMID:27103953

  2. Examining alternative scoring rubrics on a statewide test: The impact of different scoring methods on science and social studies performance assessments

    Creighton, Susan Dabney

    There is no consensus regarding the most reliable and valid scoring methods for the assessment of higher order thinking skills. Most of the research on alternative formats has focused on the scoring of writing ability. This study examined the value of different types of performance assessment scoring guides on state mandated science and social studies tests. A proportional stratified sample of raters were randomly assigned to one of four scoring groups: checklist, analytic rubric, holistic rubric, and generic rubrics. A fifth method, the weighted analytic rubric, was included by applying an algorithmic formula to the scores assigned by raters using the analytic rubric. A comparison of the mean scores for the five scoring groups suggests that there may be a difference in the way raters applied the rubric for each group. Although the literature suggests that it is possible to achieve high levels of inter-rater reliability, across forms of scoring, phi coefficients of moderate strength were obtained for three of the four constructed-response items. Results for each scoring group were compared indicating that item complexity may impact the level of inter-rate, reliability and the selection of the most reliable rubric for each discipline. Analytic rubrics appear to achieve more reliable results with less complex items. A multitrait-multimethod approach was utilized to investigate the external validity of the social studies and science tasks. As expected, there tended to be a stronger association between the PACT science constructed-response scores with scores based on science multiple-choice scores than between the science constructed-response scores and the writing ability subtest scores. A similar pattern was seen with social studies items. These results provide some evidence for the validity of the performance assessments. A post study survey completed by raters provided qualitative information regarding their thought processes and their primary focus during the

    Full Text Available English language oral teaching and testing has usually been a problematic issue in the Nigerian educational system. This study thus examines the way Continuous Assessment (CA and examination results compare in the ENG 121 English orals practical class in FCE, Okene. This is to assess the impact of the innovative pragmatic approach of continuous practice of pronunciation employed by the course lecturer. The performance levels of the candidates are ranked on a scale of 1-10. A frequency and percentage comparative ranking of the scores is done. A tabular and graphic presentation of the scores reveals the students’ performance is generally above average, indicating the success of the pragmatic approach. Nevertheless, a more favourable performance in the CA than in the examination is observed. The paper concludes that the innovative approach greatly helped the students to improve on their performance in spoken English. It thus recommends, among other things, that pragmatic teaching procedure should be constantly employed in teaching Nigerian students to the end of Nigeria attaining her true position in the comity of nations.Key words: English orals, Speech work class, Nigerian education system, functional education, innovation, CAand examination scores

  4. Total Mini-Mental State Examination score and regional cerebral blood flow using Z score imaging and automated ROI analysis software in subjects with memory impairment

    International Nuclear Information System (INIS)

    The Mini-Mental State Examination (MMSE) is considered a useful supplementary method to diagnose dementia and evaluate the severity of cognitive disturbance. However, the region of the cerebrum that correlates with the MMSE score is not clear. Recently, a new method was developed to analyze regional cerebral blood flow (rCBF) using a Z score imaging system (eZIS). This system shows changes of rCBF when compared with a normal database. In addition, a three-dimensional stereotaxic region of interest (ROI) template (3DSRT), fully automated ROI analysis software was developed. The objective of this study was to investigate the correlation between rCBF changes and total MMSE score using these new methods. The association between total MMSE score and rCBF changes was investigated in 24 patients (mean age±standard deviation (SD) 71.5±9.2 years; 6 men and 18 women) with memory impairment using eZIS and 3DSRT. Step-wise multiple regression analysis was used for multivariate analysis, with the total MMSE score as the dependent variable and rCBF change in 24 areas as the independent variable. Total MMSE score was significantly correlated only with the reduction of left hippocampal perfusion but not with right (P<0.01). Total MMSE score is an important indicator of left hippocampal function. (author)

    The Addenbrooke's Cognitive Examination Revised (ACE-R) is a rapid screening battery, including five sub-scales to explore different cognitive domains: attention/orientation, memory, fluency, language and visuospatial. ACE-R is considered useful in discriminating cognitively normal subjects from patients with mild dementia. The aim of present study was to provide normative values for ACE-R total score and sub-scale scores in a large sample of Italian healthy subjects. Five hundred twenty-six Italian healthy subjects (282 women and 246 men) of different ages (age range 20-93 years) and educational level (from primary school to university) underwent ACE-R and Montreal Cognitive Assessment (MoCA). Multiple linear regression analysis revealed that age and education significantly influenced performance on ACE-R total score and sub-scale scores. A significant effect of gender was found only in sub-scale attention/orientation. From the derived linear equation, a correction grid for raw scores was built. Inferential cut-offs score were estimated using a non-parametric technique and equivalent scores (ES) were computed. Correlation analysis showed a good significant correlation between ACE-R adjusted scores with MoCA adjusted scores (r = 0.612, p population useful for both clinical and research purposes.

    Several studies document high levels of job satisfaction among certified nurses, but no study has examined job satisfaction and factors influencing job satisfaction of certified multiple sclerosis (MS) nurses. This study tested a theoretical model proposing that two organizational factors, colleague relationships and benefits, will predict job satisfaction. Job satisfaction was represented by four factors: autonomy, professional status, professional growth, and time efficiency. Participants included MS nurses certified for 6 months or more practicing mostly in three countries (Canada, Great Britain, and the United States) who anonymously completed the Misener Nurse Practitioner Job Satisfaction Scale, an overall job satisfaction rating, and demographic information. Findings indicate that colleague relationships and benefits significantly estimated organization structure and that autonomy, professional status, professional growth, and time efficiency significantly estimated job satisfaction; furthermore, organization factors such as colleague relationships and benefits significantly predict job satisfaction. Among the countries, several statistically significant differences were observed between job satisfaction factors as well as items in both organization and job satisfaction subscales. Average factor scores among the countries were mostly rated satisfactory. The International Organization of Multiple Sclerosis Nurses Executive Board plans to use the study findings to see how it needs to focus efforts as an organization toward enhancing and standardizing MS care and develop MS nurse professionalism worldwide.

    Many educated adults possess exact mathematical abilities in addition to an approximate, intuitive sense of number, often referred to as the Approximate Number System (ANS). Here we investigate the link between ANS precision and mathematics performance in adults by testing participants on an ANS-precision test and collecting their scores on the Scholastic Aptitude Test (SAT), a standardized college-entrance exam in the USA. In two correlational studies, we found that ANS precision correlated with SAT-Quantitative (i.e., mathematics) scores. This relationship remained robust even when controlling for SAT-Verbal scores, suggesting a small but specific relationship between our primitive sense for number and formal mathematical abilities.

    2004-12-01

    Full Text Available Abstract Background Identification and treatment of unrecognised asthmatics in the community is important for improving the health of the individual and minimising cost and quality of life burden. It is not practical to offer clinical diagnostic assessment to whole communities, and a simple tool such as a questionnaire is required to identify a smaller target group. Conventional questionnaire screening methods which separate individuals into positive and negative categories have resulted in large numbers of individuals requiring clinical assessment. This study has therefore developed and tested a weighted scoring system that prioritises those most urgently in need, based on their questionnaire responses. Methods A stratified random sample of adult respondents to a general practice postal questionnaire survey were categorised 'asthmatic' or 'non-asthmatic' according to three expert physicians' opinions. Based on this categorisation, logistic regression was used to derive weights reflecting the relative importance of each question in predicting asthma, allowing calculation of weighted scores reflecting likelihood of asthma. Respondents scoring higher than a chosen threshold would be offered diagnostic examination. Results Age and presence of wheeze were most influential (weight 3 and overall weighted scores ranged from -1 to 13. Positive predictive values (PPV were estimated. For example, setting the threshold score at nine gave an estimated PPV for asthma diagnosis of 93.5%, a threshold score of seven corresponded to PPV 78.8%. PPV estimates were supported by examining 145 individuals from a new survey. Conclusion Weighted scoring of questionnaire responses provides a method for evaluating the priority level of an individual 'at a glance', minimising the resource wastage of examining false positives.

    The underlying neural determinants of general intelligence have been studied intensively, and seem to derive from the anatomical and functional characteristics of a frontoparietal network. Little is known, however, about the underlying neural correlates of domain-specific cognitive abilities, the other factors hypothesized to explain individual performance on intelligence tests. Previous preliminary studies have suggested that spatially distinct neural structures do not support domain-specific cognitive abilities. To test whether differences between abilities that affect performance on verbal and performance tasks derive instead from the morphological features of a single anatomical network, we assessed in two independent samples of healthy human participants (N = 83 and N = 58; age range, 5–57 years) the correlation of cortical thickness with the magnitude of the verbal intelligence quotient (VIQ)-performance intelligence quotient (PIQ) discrepancy. We operationalized the VIQ-PIQ discrepancy by regressing VIQ onto PIQ (VIQ-regressed-on-PIQ score), and by regressing PIQ onto VIQ (PIQ-regressed-on-VIQ score). In both samples, a progressively thinner cortical mantle in anterior and posterior regions bilaterally was associated with progressively greater (more positive) VIQ-regressed-on-PIQ scores. A progressively thicker cortical mantle in anterior and posterior regions bilaterally was associated with progressively greater (more positive) PIQ-regressed-on-VIQ scores. Variation in cortical thickness in these regions accounted for a large portion of the overall variance in magnitude of the VIQ-PIQ discrepancy.

    The mental status examination is the most difficult and time-consuming portion of the neurological examination. A complete mental status examination requires the examiner to assess alertness, memory, language, praxis, gnosis, attention, and visual-spatial functions. Findings of the mental status need to be interpreted in terms of severity of deficits, nature of the deficits, likely etiology, and likely area of corresponding brain injury. The performance of an accurate, complete, and detailed ...

    Background and purpose: salivary flow rates alone are not sufficient to quantify all aspects of radioxerostomia. This is a problem in studies aiming to reduce radioxerostomia. The aim of this study was to evaluate the association between objectively measured salivary flow rate and subjective xerostomia ratings by the physician (RTOG scale) or the patients (quality of life [QoL] questionnaire). Patients and methods: in a case-control study patients who underwent recall for oral cancer were screened. Inclusion criteria for this diagnostic, noninterventional study were: history of oral carcinoma, surgical and radiation therapy, time interval from start of radiation therapy > 90 days, salivary glands within the radiation field. The control group consisted of patients, who had not received radiotherapy. RTOG salivary gland score, quality of life (EORTC QLQ-C30 and H and N35), and sialometry were recorded. Results: patients with RTOG score 0 had mean salivary flow rates of 0.3 ml/min, those with RTOG 1 0.12 ml/min, RTOG 2 0.02 ml/min, and RTOG 3 < 0.01 ml/min. RTOG score 4 (total fibrosis) did not occur. Based on salivary flow rates, all patients were grouped into xerostomia < 0.2 ml/min (30 patients) and nonxerostomia (twelve patients). QoL results revealed significant differences between patients with xerostomia and nonxerostomia for physical function, dyspnea, swallowing, social eating, dry mouth, nutritional support, and a tendency to higher values for appetite loss. Conclusion: the correlation between ''subjective'' QoL parameters and salivary flow was confirmed. The different subjective aspects of radioxerostomia seem to be better differentiated by the EORTC QoL questionnaire. (orig.)

    Full Text Available The purpose of this study was to determine whether or not the specific item checklist (checklist and global rating scale (GRS scores are correlated in practical skills examinations (PSEs. Professional behaviour was evaluated using both the checklist and GRS scores for 183 students in three PSEs. Mean, standard deviation, and correlation for checklist and GRS scores were calculated for each station, within each PSE. Pass rate for checklist and GRS was determined for each PSE, as well as for each individual checklist item within each PSE. Overall, pass rate was high for both checklist and GRS evaluations of professional behaviour in all PSEs. Generally, mean scores for the checklist and GRS were high, with low standard deviations, resulting in low data variability. Spearman correlation between total checklist and GRS scores was statistically significant for two out of five stations in PSE 1, five out of six stations in PSE 2, and three out of four stations in PSE 3. The GRS is comparable to the checklist for evaluation of professional behaviour in physical therapy (PT students. The correlation between the checklist and GRS appears to become stronger in the assessment of more advanced students.

  2. A Plea to Reassess the Role of United States Medical Licensing Examination Step 1 Scores in Residency Selection.

    Science.gov (United States)

    Prober, Charles G; Kolars, Joseph C; First, Lewis R; Melnick, Donald E

    2016-01-01

    The three-step United States Medical Licensing Examination (USMLE) was developed by the National Board of Medical Examiners and the Federation of State Medical Boards to provide medical licensing authorities a uniform evaluation system on which to base licensure. The test results appear to be a good measure of content knowledge and a reasonable predictor of performance on subsequent in-training and certification exams. Nonetheless, it is disconcerting that the test preoccupies so much of students' attention with attendant substantial costs (in time and money) and mental and emotional anguish. There is an increasingly pervasive practice of using the USMLE score, especially the Step 1 component, to screen applicants for residency. This is despite the fact that the test was not designed to be a primary determinant of the likelihood of success in residency. Further, relying on Step 1 scores to filter large numbers of applications has unintended consequences for students and undergraduate medical education curricula. There are many other factors likely to be equally or more predictable of performance during residency. The authors strongly recommend a move away from using test scores alone in the applicant screening process and toward a more holistic evaluation of the skills, attributes, and behaviors sought in future health care providers. They urge more rigorous study of the characteristics of students that predict success in residency, better assessment tools for competencies beyond those assessed by Step 1 that are relevant to success, and nationally comparable measures from those assessments that are easy to interpret and apply.

    Full Text Available Introduction: There is great variation in the knowledge base of Emergency Medicine (EM interns in July. The first objective knowledge assessment during residency does not occur until eight months later, in February, when the American Board of EM (ABEM administers the in-training examination (ITE. In 2013, the National Board of Medical Examiners (NBME released the EM Advanced Clinical Examination (EM-ACE, an assessment intended for fourth-year medical students. Administration of the EM-ACE to interns at the start of residency may provide an earlier opportunity to assess the new EM residents’ knowledge base. The primary objective of this study was to determine the correlation of the NBME EM-ACE, given early in residency, with the EM ITE. Secondary objectives included determination of the correlation of the United States Medical Licensing Examination (USMLE Step 1 or 2 scores with early intern EM-ACE and ITE scores and the effect, if any, of clinical EM experience on examination correlation. Methods: This was a multi-institutional, observational study. Entering EM interns at six residencies took the EM-ACE in July 2013 and the ABEM ITE in February 2014. We collected scores for the EMACE and ITE, age, gender, weeks of clinical EM experience in residency prior to the ITE, and USMLE Step 1 and 2 scores. Pearson’s correlation and linear regression were performed. Results: Sixty-two interns took the EM-ACE and the ITE. The Pearson’s correlation coefficient between the ITE and the EM-ACE was 0.62. R-squared was 0.5 (adjusted 0.4. The coefficient of determination was 0.41 (95% CI [0.3-0.8]. For every increase of one in the scaled EM-ACE score, we observed a 0.4% increase in the EM in-training score. In a linear regression model using all available variables (EM-ACE, gender, age, clinical exposure to EM, and USMLE Step 1 and Step 2 scores, only the EM-ACE score was significantly associated with the ITE (p<0.05. We observed significant colinearity

    2016-04-01

    The purpose of the current study was to identify Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) correlates of police officer integrity violations and other problem behaviors in an archival database with original MMPI item responses and collateral information regarding integrity violations obtained for 417 male officers. In Study 1, we estimated MMPI-2-RF scores from the MMPI item pool (which includes approximately 80% of the MMPI-2-RF items) in a normative sample, a psychiatric inpatient sample, and a police officer sample, and conducted analyses that demonstrated the comparability of estimated and full scale scores for 41 of the 51 MMPI-2-RF scales. In Study 2, we correlated estimated MMPI-2-RF scores with information about subsequent integrity violations and problem behaviors from the integrity violation data set. Several meaningful associations were obtained, predominately with scales from the emotional, thought, and behavioral dysfunction domains of the MMPI-2-RF. Application of a correction for range restriction yielded substantially improved validity estimates. Finally, we calculated relative risk ratios for the statistically significant findings using cutoffs lower than 65T, which is traditionally used to identify clinically significant elevations, and found several meaningful relative risk ratios.

    Full Text Available Objective. The main aim of this study was to verify the sensitivity and specificity of Addenbrooke’s Cognitive Examination-Revised (ACE-R in discriminating between Parkinson’s disease (PD with normal cognition (PD-NC and PD with mild cognitive impairment (PD-MCI and between PD-MCI and PD with dementia (PD-D. We also evaluated how ACE-R correlates with neuropsychological cognitive tests in PD. Methods. We examined three age-matched groups of PD patients diagnosed according to the Movement Disorder Society Task Force criteria: PD-NC, PD-MCI, and PD-D. ROC analysis was used to establish specific cut-off scores of ACE-R and its domains. Correlation analyses were performed between ACE-R and its subtests with relevant neuropsychological tests. Results. Statistically significant differences between groups were demonstrated in global ACE-R scores and subscores, except in the language domain. ACE-R cut-off score of 88.5 points discriminated best between PD-MCI and PD-NC (sensitivity 0.68, specificity 0.91; ACE-R of 82.5 points distinguished best between PD-MCI and PD-D (sensitivity 0.70, specificity 0.73. The verbal fluency domain of ACE-R demonstrated the best discrimination between PD-NC and PD-MCI (cut-off score 11.5; sensitivity 0.70, specificity 0.73 while the orientation/attention subscore was best between PD-MCI and PD-D (cut-off score 15.5; sensitivity 0.90, specificity 0.97. ACE-R scores except for ACE-R language correlated with specific cognitive tests of interest.

  20. Using estimated factor scores from a bifactor analysis to examine the unique effects of the latent variables measured by the WAIS-IV on academic achievement.

    Kranzler, John H; Benson, Nicholas; Floyd, Randy G

    2015-12-01

    This study used estimated factor scores from a bifactor analysis of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) to examine the unique effects of its latent variables on academic achievement. In doing so, we addressed the potential limitation of multicollinearity in previous studies of the incremental validity of the WAIS-IV. First, factor scores representing psychometric g and 4 group factors representing the WAIS-IV index scales were computed from a bifactor model. Subtest and composite scores for the Wechsler Individual Achievement Test-Third Edition (WIAT-II) were then predicted from these estimated factor scores in simultaneous multiple regression. Results of this study only partially replicated the findings of previous research on the incremental validity of scores that can be derived from performance on the WAIS-IV. Although we found that psychometric g is the most important underlying construct measured by the WAIS-IV for the prediction of academic achievement in general, results indicated that the unique effect of Verbal Comprehension is also important for predicting achievement in reading, spelling, and oral communication skills. Based on these results, measures of both psychometric g and Verbal Comprehension could be cautiously interpreted when considering high school students' performance in these areas of achievement.

    Full Text Available Leaders get things done through building relationships and getting tasks done in a timely manner. The focus on leadership of people in different cultures are of great importance to managers since they want tasks done in a timely manner and healthy relationships maintained with their vendors and customers. To explore the orientation of respondents in the Bahamas, this research focused on the differences of male and female Bahamian respondents. From the responses of 211 individuals in Nassau, it appears that Bahamians have significantly different scores on the relationship and task orientations. They are more relationship-oriented. The responses of 46 males and 165 females demonstrate significant differences based on gender. The information is useful for international managers and expatriates working in the Bahamas. Suggestions for future research and implications are presented.

    2016-01-01

    The Circumplex Scales of Interpersonal Values (CSIV) is a 64-item self-report measure of goals from each octant of the interpersonal circumplex. We used item response theory methods to compare whether dominance models or ideal point models best described how people respond to CSIV items. Specifically, we fit a polytomous dominance model called the generalized partial credit model and an ideal point model of similar complexity called the generalized graded unfolding model to the responses of 1,893 college students. The results of both graphical comparisons of item characteristic curves and statistical comparisons of model fit suggested that an ideal point model best describes the process of responding to CSIV items. The different models produced different rank orderings of high-scoring respondents, but overall the models did not differ in their prediction of criterion variables (agentic and communal interpersonal traits and implicit motives).

    on other sub-tests of the LDE such as Turkish, social sciences, and foreign languages. Therefore, more studies are needed in order to investigate factors affecting students’ performance in the LDE. Hence, it is thought to be important to analyze the relationship between the means of the academic achievement scores of the students in English course that they had from different means of measurement and the raw scores of LDT English sub-test. In this regard, the purpose of this study is to investigate the correlation between academic averages of elementary English course and English sub-test scores in the Level Determination Examination (LDE with structural equation modelling. Method: The correlative investigation model was used in the research (McMillan & Schumacher, 2006. This model is one of the most commonly applied models in the related literature (Cohen, Manion & Morrison, 2003. A struc¬tural equation model was formed in order to better illustrate the correlation between variables in the research (Brown, 2006. Structural equation model connects the predictive structural correlations holding between the variables in the regression model to the covered factor structures in the factor analysis through a comprehensive analysis (Sümer, 2000. The population of this study consisted of students in elementary schools within the borders of Nigde province of Turkey. In order to detect the sampling of the study, from elementary schools in cosmos, 375 students from six public elementary schools were chosen according to random sampling method (Karasar, 2005. In this research, LISREL 8.51 structural equation programme was used in model establishing by using the observed variables predicted.

  7. Incidence of Brain Atrophy and Decline in Mini-Mental State Examination Score After Whole-Brain Radiotherapy in Patients With Brain Metastases: A Prospective Study

    International Nuclear Information System (INIS)

    Purpose: To determine the incidence of brain atrophy and dementia after whole-brain radiotherapy (WBRT) in patients with brain metastases not undergoing surgery. Methods and Materials: Eligible patients underwent WBRT to 40 Gy in 20 fractions with or without a 10-Gy boost. Brain magnetic resonance imaging or computed tomography and Mini-Mental State Examination (MMSE) were performed before and soon after radiotherapy, every 3 months for 18 months, and every 6 months thereafter. Brain atrophy was evaluated by change in cerebrospinal fluid-cranial ratio (CCR), and the atrophy index was defined as postradiation CCR divided by preradiation CCR. Results: Of 101 patients (median age, 62 years) entering the study, 92 completed WBRT, and 45, 25, and 10 patients were assessable at 6, 12, and 18 months, respectively. Mean atrophy index was 1.24 ± 0.39 (SD) at 6 months and 1.32 ± 0.40 at 12 months, and 18% and 28% of the patients had an increase in the atrophy index by 30% or greater, respectively. No apparent decrease in mean MMSE score was observed after WBRT. Individually, MMSE scores decreased by four or more points in 11% at 6 months, 12% at 12 months, and 0% at 18 months. However, about half the decrease in MMSE scores was associated with a decrease in performance status caused by systemic disease progression. Conclusions: Brain atrophy developed in up to 30% of patients, but it was not necessarily accompanied by MMSE score decrease. Dementia after WBRT unaccompanied by tumor recurrence was infrequent

    Full Text Available Mostafa Yakoot,1 Amel Salem,2 Sherine Helmy3 1Green Clinic and Research Center, 2Mabarrah Clinics, 3Pharco Pharmaceutical Industries, Alexandria, Egypt Background: Mild cognitive impairment encompasses the clinical continuum between physiologic age-related cognitive changes and dementia. A variety of medications, including herbal preparations (in particular Ginkgo biloba and Panax ginseng, have been advocated as treatments for cognitive impairment in the elderly. In this study, we investigated the effect of an already marketed dietary supplement (Memo® combining 750 mg of lyophilized royal jelly with standardized extracts of G. biloba 120 mg and P. ginseng 150 mg on Mini-Mental State Examination (MMSE scores in patients with mild cognitive impairment. Methods: Sixty-six subjects presenting with forgetfulness and satisfying the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR clinical criteria for mild cognitive impairment were randomly divided into an experimental group treated with one Memo capsule before breakfast daily for 4 weeks and a control group who took placebo. The mean change in MMSE score from baseline and reported adverse effects were compared between the two groups. Results: The mean change in MMSE score in the group treated with Memo for 4 weeks was significantly greater than in the control group (+2.07 versus +0.13, respectively by the Student’s t-test (t = 6.485, P < 0.0001. This was also true after adjusting for age as a covariate and educational level as a factor nested within the treatment groups in a general linear model (analysis of covariance, F = 9.675 [corrected model], P < 0.0001. Conclusion: This combined triple formula may be beneficial in treating the cognitive decline that occurs during the aging process as well as in the early phases of pathologic cognitive impairment typical of insidious-onset vascular dementia and in the early stages of Alzheimer’s disease.

    A psychiatric patient prisoner is certified and treated involuntarily under the Saskatchewan Mental Health Services Act at the Regional Psychiatric Center if he/she is mentally ill, incapable of making treatment decision and is likely to cause harm to self or others. This retrospective study examined the treatment of certified patients during a 12-year period (1996 to 2007). A total of 112 patients were treated using 263 certifications during 163 separate hospital admissions. Fifty of all the certified patients (44.6%) required more than one certification, and out of these, 72% required another certification within three months of the first certification. Among those certified, schizophrenia and related psychosis (65.2%, n = 73), substance use disorder (50%, n = 56) and antisocial personality disorder (58%, n = 65) were the most common discharge diagnoses and antipsychotics, the most frequent discharge medications. Global Assessment of Functioning score of patients improved significantly (p treatment. This benefit may be enhanced if the statutory duration of certification can be increased to account for the length of time required for the adequate resolution of symptoms and to reduce the need for repeat certification.

  7. National Board Certified Teachers andTheir Students' Achievement

    2004-09-01

    Full Text Available Contemporary research on teaching indicates that teachers are powerful contributors to students’ academic achievement, though the set and interrelationships of characteristics that make for high-quality and effective teaching have yet to be satisfactorily determined. Nevertheless, on the basis of the extant research and a vision of exemplary teaching, the National Board for Professional Teaching Standards stipulated a definition of a superior teacher. The Board did this without empirical evidence to support their claim that teachers’ who meet the standards set by the Board were superior in promoting academic achievement to those who did not meet those standards. In the 17 years since the founding of the National Board, only a few empirical studies have addressed this important issue. In this study we compare the academic performance of students in the elementary classrooms of 35 National Board Certified teachers and their non-certified peers, in 14 Arizona school districts. Board Certified teachers and their principals provide additional information about these teachers and their schools. Four years of results from the Stanford Achievement Tests in reading, mathematics and language arts, in grades three through six, were analyzed. In the 48 comparisons (four grades, four years of data, three measures of academic performance, using gain scores adjusted for students’ entering ability, the students in the classes of National Board Certified Teachers surpassed students in the classrooms of non-Board certified teachers in almost threequarters of the comparisons. Almost one-third of these differences were statistically significant. In the cases where the students of non-Board certified teachers gained more in an academic year, none of the differences found were statistically significant. Effect size, translated into grade equivalents, informs us that the gains made by students of Board Certified teachers were over one month greater than the

  13. Assessment of long-term impact of formal certified cardiopulmonary resuscitation training program among nurses

    Directory of Open Access Journals (Sweden)

    P P Saramma

    2016-01-01

    Full Text Available Context: Cardiopulmonary resuscitation (CPR and emergency cardiovascular care guidelines are periodically renewed and published by the American Heart Association. Formal training programs are conducted based on these guidelines. Despite widespread training CPR is often poorly performed. Hospital educators spend a significant amount of time and money in training health professionals and maintaining basic life support (BLS and advanced cardiac life support (ACLS skills among them. However, very little data are available in the literature highlighting the long-term impact of these training. Aims: To evaluate the impact of formal certified CPR training program on the knowledge and skill of CPR among nurses, to identify self-reported outcomes of attempted CPR and training needs of nurses. Setting and Design : Tertiary care hospital, Prospective, repeated-measures design. Subjects and Methods: A series of certified BLS and ACLS training programs were conducted during 2010 and 2011. Written and practical performance tests were done. Final testing was undertaken 3-4 years after training. The sample included all available, willing CPR certified nurses and experience matched CPR noncertified nurses. Statistical Analysis Used: SPSS for Windows version 21.0. Results: The majority of the 206 nurses (93 CPR certified and 113 noncertified were females. There was a statistically significant increase in mean knowledge level and overall performance before and after the formal certified CPR training program (P = 0.000. However, the mean knowledge scores were equivalent among the CPR certified and noncertified nurses, although the certified nurses scored a higher mean score (P = 0.140. Conclusions: Formal certified CPR training program increases CPR knowledge and skill. However, significant long-term effects could not be found. There is a need for regular and periodic recertification.

  14. Certifying nonlocality from separable marginals

    Science.gov (United States)

    Vértesi, Tamás; Laskowski, Wiesław; Pál, Károly F.

    2014-01-01

    Imagine three parties, Alice, Bob, and Charlie, who share a state of three qubits such that all two-party reduced states A-B, A-C, and B-C are separable. Suppose that they have information only about these marginals but not about the global state. According to recent results, there exists an example for a set of three separable two-party reduced states that is only compatible with an entangled global state. In this paper, we show a stronger result by exhibiting separable two-party reduced states A-B, A-C, and B-C, such that any global state compatible with these marginals is nonlocal. Hence, we obtain that nonlocality of multipartite states can be certified from information only about separable marginals.

    We describe a new algorithm, the $(k,\\ell)$-pebble game with colors, and use it obtain a characterization of the family of $(k,\\ell)$-sparse graphs and algorithmic solutions to a family of problems concerning tree decompositions of graphs. Special instances of sparse graphs appear in rigidity theory and have received increased attention in recent years. In particular, our colored pebbles generalize and strengthen the previous results of Lee and Streinu and give a new proof of the Tutte-Nash-Williams characterization of arboricity. We also present a new decomposition that certifies sparsity based on the $(k,\\ell)$-pebble game with colors. Our work also exposes connections between pebble game algorithms and previous sparse graph algorithms by Gabow, Gabow and Westermann and Hendrickson.

    2010-01-01

    In order to look for phenotypic correlation between hip (HD) and elbow (ED) dysplasia, we used radiographic scoring obtained from 1,411 dogs of different breeds, which were evaluated for authoritative grading of both conditions. In this population, we found that the risk ratio for an animal to be simultaneously affected by HD and ED is 1.67. For a dog with ED, the risk ratio to be affected by HD increases as the ED grade increases. Similarly, for a dog affected by HD, the risk ratio to be affected by ED increases as the HD grade increases. In a dog affected by HD or ED, the clinician should look for the second condition in the same animal. Due to the low, yet positive correlation, selection against one trait will not affect the other trait sufficiently. Therefore selection has to be conducted at reduction of HD as well as reduction of ED. PMID:19997665

    Proof-Carrying Code brings two big challenges to the research field of programming languages.One is to seek more expressive logics or type systems to specify or reason about the properties of low-level or high-level programs.The other is to study the technology of certifying compilation in which the compiler generates proofs for programs with annotations.This paper presents our progress in the above two aspects.A pointer logic was designed for PointerC (a C-like programming language) in our research.As an extension of Hoare logic,our pointer logic expresses the change of pointer information for each statement in its inference rules to support program verification.Meanwhile,based on the ideas from CAP (Certified Assembly Programming) and SCAP (Stack-based Certified Assembly Programming),a reasoning framework was built to verify the properties of object code in a Hoare style.And a certifying compiler prototype for PointerC was implemented based on this framework.The main contribution of this paper is the design of the pointer logic and the implementation of the certifying compiler prototype.In our certifying compiler,the source language contains rich pointer types and operations and also supports dynamic storage allocation and deallocation.

  1. An investigation of safety climate in OHSAS 18001-certified and non-certified organizations.

    Science.gov (United States)

    Ghahramani, Abolfazl

    2016-09-01

    Many organizations worldwide have implemented Occupational Health and Safety Assessment Series (OHSAS) 18001 in their premises because of the assumed positive effects of this standard on safety. Few studies have analyzed the effect of the safety climate in OHSAS 18001-certified organizations. This case-control study used a new safety climate questionnaire to evaluate three OHSAS 18001-certified and three non-certified manufacturing companies in Iran. Hierarchical regression indicated that the safety climate was influenced by OHSAS implementation and by safety training. Employees who received safety training had better perceptions of the safety climate and its dimensions than other respondents within the certified companies. This study found that the implementation of OHSAS 18001 does not guarantee improvement of the safety climate. This study also emphasizes the need for high-quality safety training for employees of the certified companies to improve the safety climate. PMID:27108658

  2. Industrial-Strength Formally Certified SAT Solving

    CERN Document Server

    Darbari, Ashish; Marques-Silva, Joao

    2009-01-01

    Boolean Satisfiability (SAT) solvers are now routinely used in the verification of large industrial problems. However, their application in safety-critical domains such as the railways, avionics, and automotive industries requires some form of assurance for the results, as the solvers can (and sometimes do) have bugs. Unfortunately, the complexity of modern, highly optimized SAT solvers renders impractical the development of direct formal proofs of their correctness. This paper presents an alternative approach where an untrusted, industrial-strength, SAT solver is plugged into a trusted, formally certified, SAT proof checker to provide industrial-strength certified SAT solving. The key novelties and characteristics of our approach are (i) that the checker is automatically extracted from the formal development, (ii), that the combined system can be used as a standalone executable program independent of any supporting theorem prover, and (iii) that the checker certifies any SAT solver respecting the agreed form...

    Kim, Dae-Hwan; Mak, Kwok-Kei

    2016-01-01

    This study examined the gender-specific associations between cohabitation with parents and stress using an econometric approach. A total of 13,565 (41.7% men and 58.3% women) Korean adults aged 20-59 years from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008 to 2011 were pooled. They reported their gender, age, marital status, education level, employment status, income, home ownership, and cohabitation status with their parents. The association of living with parents and stress, as well as the gender difference in the association, was investigated using propensity score matching and the average treatment effect on the treated. Adults with higher education and income, not owning a house, or living in larger cities were less likely to live with parents. Stress was associated with having children and participating in the labor market for both married men and women. Moreover, living with parents was a protective factor for stress among husbands, but a risk factor for wives in Korea. Gender differences existed in the association between cohabitation with parents and stress. Greater stress was related to cohabiting with parents and working for married women. PMID:26211934

  11. Norwegian farmers ceasing certified organic production: characteristics and reasons.

    Flaten, Ola; Lien, Gudbrand; Koesling, Matthias; Løes, Anne-Kristin

    2010-12-01

    This article examines the characteristics of and reasons for Norwegian farmers' ceasing or planning to cease certified organic production. We gathered cross-sectional survey data in late 2007 from organic farmers deregistering between January 2004 and September 2007 (n=220), and similar data from a random sample of farmers with certified organic management in 2006 (n=407). Of the respondents deregistering by November 2007, 17% had quit farming altogether, 61% now farmed conventionally, and 21% were still farming by organic principles, but without certification. Nearly one in four organic farmers in 2007 indicated that they planned to cease certification within the next 5-10 years. From the two survey samples, we categorised farmers who expect to be deregistered in 5-10 years into three groups: conventional practices (n=139), continuing to farm using organic principles (uncertified organic deregistrants, n=105), and stopped farming (n=33). Of the numerous differences among these groups, two were most striking: the superior sales of uncertified organic deregistrants through consumer-direct marketing and the lowest shares of organic land among conventional deregistrants. We summarised a large number of reasons for deregistering into five factors through factor analysis: economics, regulations, knowledge-exchange, production, and market access. Items relating to economics and regulations were the primary reasons offered for opting out. The regression analysis showed that the various factors were associated with several explanatory variables. Regulations, for example, figured more highly among livestock farmers than crop farmers. The economic factor strongly reflected just a few years of organic management. Policy recommendations for reducing the number of dropouts are to focus on economics, environmental attitudes, and the regulatory issues surrounding certified organic production. PMID:20702020

  19. Preliminary Study on Willingness to Pay for Environmentally Certified Wood Products Among Consumers in Malaysia

    Science.gov (United States)

    Mohamed, Shukri; Lukhman Ibrahim, Muhamad

    Consumers are expected to demand and would be willing to pay a price premium for environment-friendly products stemming from the growing global environmental consumerism. While consumers in the developed countries are reported to be willing to pay a price premium for environmentally certified wood products, there is hardly any study on consumers` willingness in other markets. This preliminary study examines consumer willingness to pay a price premium for environmentally certified wood products in Malaysia. Data were obtained using a self-administered questionnaire distributed to 100 systematically-sampled, mall-intercepted respondents. Results indicated that some 38% of the respondents would be willing to pay an average of 14.4% more for environmentally certified wood products.

  1. Examination of the Five Comparable Component Scores of the Diet Quality Indexes HEI-2005 and RC-DQI Using a Nationally Representative Sample of 2–18 Year Old Children: NHANES 2003–2006

    Sibylle Kranz

    2013-01-01

    Full Text Available Obesity has been associated with low diet quality and the suboptimal intake of food groups and nutrients. Two composite diet quality measurement tools are appropriate for Americans 2–18 years old: the Healthy Eating Index (HEI 2005 and the Revised Children’s Diet Quality Index (RC-DQI. The five components included in both indexes are fruits, vegetables, total grains, whole grains, and milk/dairy. Component scores ranged from 0 to 5 or 0 to 10 points with lower scores indicating suboptimal intake. To allow direct comparisons, one component was rescaled by dividing it by 2; then, all components ranged from 0 to 5 points. The aim of this study was to directly compare the scoring results of these five components using dietary data from a nationally representative sample of children (NHANES 2003–2006, . Correlation coefficients within and between indexes showed less internal consistency in the HEI; age- and ethnic-group stratified analyses indicated higher sensitivity of the RC-DQI. HEI scoring was likely to dichotomize the population into two groups (those with 0 and those with 5 points, while RC-DQI scores resulted in a larger distribution of scores. The scoring scheme of diet quality indexes for children results in great variation of the outcomes, and researchers must be aware of those effects.

  2. Mastitis and related management factors in certified organic dairy herds in Sweden

    2006-07-01

    Full Text Available Abstract Background Mastitis is one of the major threats to animal health, in organic farming as well as conventional. Preliminary studies of organic dairy herds have indicated better udder health in such herds, as compared to conventional herds. The aim of this paper was to further study mastitis and management related factors in certified organic dairy herds. Methods An observational study of 26 certified organic dairy herds in mid-eastern Sweden was conducted during one year. A large-animal practitioner visited the herds three times and clinically examined and sampled cows, and collected information about general health and management routines. Data on milk production and disorders treated by a veterinarian in the 26 herds, as well as in 1102 conventional herds, were retrieved from official records. Multivariable logistic regression was used to assess associations between herd type (organic vs. conventional and incidence of disorders. Results The organic herds that took part in the study ranged in size from 12 to 64 cows, in milk production from 3772 to 10334 kg per cow and year, and in bulk milk somatic cell counts from 83000 to 280000 cells/ml. The organic herds were found to have a lower incidence of clinical mastitis, teat injuries, and a lower proportion of cows with a high somatic cell count (as indicated by the UDS, Udder Disease Score compared to conventional herds. The spectrum of udder pathogenic bacteria was similar to that found in other Swedish studies. Treatment of mastitis was found to be similar to what is practised in conventional herds. Homeopathic remedies were not widely used in the treatment of clinical mastitis. The calves in most of these organic herds suckled their dams for only a few days, which were not considered to substantially affect the udder health. The main management factor that was different from conventional herds was the feeding strategy, where organic herds used a larger share of forage. Conclusion Udder

    Randomness is a fundamental feature of nature and a valuable resource for applications ranging from cryptography and gambling to numerical simulation of physical and biological systems. Random numbers, however, are difficult to characterize mathematically, and their generation must rely on an unpredictable physical process. Inaccuracies in the theoretical modelling of such processes or failures of the devices, possibly due to adversarial attacks, limit the reliability of random number generators in ways that are difficult to control and detect. Here, inspired by earlier work on non-locality-based and device-independent quantum information processing, we show that the non-local correlations of entangled quantum particles can be used to certify the presence of genuine randomness. It is thereby possible to design a cryptographically secure random number generator that does not require any assumption about the internal working of the device. Such a strong form of randomness generation is impossible classically and possible in quantum systems only if certified by a Bell inequality violation. We carry out a proof-of-concept demonstration of this proposal in a system of two entangled atoms separated by approximately one metre. The observed Bell inequality violation, featuring near perfect detection efficiency, guarantees that 42 new random numbers are generated with 99 per cent confidence. Our results lay the groundwork for future device-independent quantum information experiments and for addressing fundamental issues raised by the intrinsic randomness of quantum theory. PMID:20393558

    The Association of Energy Engineers (AEE) has offered energy efficiency training and certification programs for over 30 years. During that time AEE has certified more than 22,000 professionals. All of our certification programs are the result of extensive industry research and program development and oversight by certification boards. For this project award, AEE proposed to work with the Department of Energy to utilize and extend existing industry recognized Certified Energy Auditor (CEA) and Certified Building Commissioning Professional (CBCP) programs under this Training Program Development Announcement. These expanded training programs will have significant impact in training professionals for building commissioning and energy auditing to achieve the goal of bringing existing buildings up to their optimal energy performance potential and ensuring that new buildings maintain their expected optimal level of performance. The goals and objectives of the training development project were achieved with the development of new training programs that are now being offered as self-sustaining commercial training and certification programs. These new programs are training and certifying professionals who are accomplishing the goal of increasing building energy performance in both existing and new buildings.

  5. Decompositions of Proper Scores

    CERN Document Server

    Bröcker, Jochen

    2008-01-01

    Scoring rules are an important tool for evaluating the performance of probabilistic forecasts. A popular example is the Brier score, which allows for a decomposition into terms related to the sharpness (or information content) and to the reliability of the forecast. This feature renders the Brier score a very intuitive measure of forecast quality. In this paper, it is demonstrated that all strictly proper scoring rules allow for a similar decomposition into reliability and sharpness related terms. This finding underpins the importance of proper scores and yields further credence to the practice of measuring forecast quality by proper scores. Furthermore, the effect of averaging multiple probabilistic forecasts on the score is discussed. It is well known that the Brier score of a mixture of several forecasts is never worse that the average score of the individual forecasts. This property hinges on the convexity of the Brier score, a property not universal among proper scores. Arguably, this phenomenon portends...

  6. Applicability of microwave digestion for analysis of elements in certified reference material by ICP-MS

    International Nuclear Information System (INIS)

    Quality of an analysis is contingent by several factors such as analysis method, equipment performance, standard preparation, sample preparation, staff competency and environmental condition. One of other major factor that also contributes to the quality of analysis results is the sample pre-treatment. In this study, sample pretreatment is involving digestion process of certified reference material using microwave oven whilst elemental analysis (Ba, Cd, Cu, Mo, Ni, Pb, and Ti) was done by Inductively Couple Plasma - Mass Spectrometer (ICP-MS). The applicability of the analytical method is confirmed by analysis results of the certified reference material (CRM). The results showed that the recovery of the elements of the CRM is 65% to 133% with Z-score value of -1.63 to 1.67. (Author)

  9. Fertilizers applied to certified organic tomato culture

    International Nuclear Information System (INIS)

    The tomato culture demands large quantities of mineral nutrients, which are supplied by synthetic fertilizers in the conventional cultivation system. In the organic cultivation system only alternative fertilizers are allowed by the certifiers and accepted as safe for humans and environment. The chemical composition of rice bran, oyster flour, cattle manure and ground charcoal, as well as soils and tomato fruits were evaluated by instrumental neutron activation analysis (INAA). The potential contribution of organic fertilizers to the enrichment of chemical elements in soil and their transfer to fruits was investigated using concentration ratios for fertilizer and soil samples, and also for soil and tomato. Results evidenced that these alternative fertilizers could be taken as important sources of Br, Ca, Ce, K, Na and Zn for the organic tomato culture. (author)

  10. Sharing the Wealth:National Board Certified Teachers and the Students Who Need Them Most

    Directory of Open Access Journals (Sweden)

    Daniel C. Humphrey

    2005-03-01

    Full Text Available It is a commonly understood problem in education that many highly qualified teachers tend to gravitate toward higher performing schools, including schools with lower minority enrollments and lower incidence of poverty. This article explores the distribution of a subset of teachers, namely, those who are National Board Certified. To what extent do these teachers' assignment choices mirror the pattern of their non-Board Certified colleagues and to what extent are they different? Part of a larger study of Board Certified Teachers in lower performing schools, the article examines the distribution of NBCTs in the six states with the largest number of them'California, Florida, Mississippi, North Carolina, Ohio, and South Carolina. The research finds that, with the exception of California, Board Certified Teachers are not equitably distributed across schools that serve different populations of students. In five of the six states examined, poor, minority, and lower performing students are far less likely to benefit from the teaching of an NBCT than are their more affluent, majority, higher performing peers. The article explores some possible explanations for the California distribution pattern as well as the kinds of incentives provided across the states for teachers to seek Board Certification and for those who earn it. The authors conclude with a rationale and a set of policy suggestions for realigning the distribution of NBCTs.

  1. The environmental efficiency of non-certified organic farming in China: a case study of paddy rice production

    OpenAIRE

    GUO, Huanxiu; Marchand, Sébastien

    2013-01-01

    This case study compares the environmental efficiency of non-certified organic and conventional rice production in southern China. Using plot-season level survey data, we first test the existence of a "technology gap" between the two types of production, and then calculate the environmental efficiency scores based on the use of pure nitrogen, which is considered as an environmentally detrimental input within the framework of the stochastic frontier analysis. Our analysis reveals that organic ...

    2013-09-01

    Full Text Available Purpose: This empirical study analyzes a questionnaire answered by a sample of ISO 9000 certified companies and a control sample of companies which have not been certified, using a multivariate predictive model. With this approach, we assess which quality practices are associated to the likelihood of the firm being certified. Design/methodology/approach: We implemented nonparametric decision trees, in order to see which variables influence more the fact that the company be certified or not, i.e., the motivations that lead companies to make sure. Findings: The results show that only four questionnaire items are sufficient to predict if a firm is certified or not. It is shown that companies in which the respondent manifests greater concern with respect to customers relations; motivations of the employees and strategic planning have higher likelihood of being certified. Research implications: the reader should note that this study is based on data from a single country and, of course, these results capture many idiosyncrasies if its economic and corporate environment. It would be of interest to understand if this type of analysis reveals some regularities across different countries. Practical implications: companies should look for a set of practices congruent with total quality management and ISO 9000 certified. Originality/value: This study contributes to the literature on the internal motivation of companies to achieve certification under the ISO 9000 standard, by performing a comparative analysis of questionnaires answered by a sample of certified companies and a control sample of companies which have not been certified. In particular, we assess how the manager’s perception on the intensity in which quality practices are deployed in their firms is associated to the likelihood of the firm being certified.Purpose: This empirical study analyzes a questionnaire answered by a sample of ISO 9000 certified companies and a control sample of companies

  5. Ligand Identification Scoring Algorithm (LISA)

    Science.gov (United States)

    Zheng, Zheng; Merz, Kenneth M.

    2011-01-01

    A central problem in de novo drug design is determining the binding affinity of a ligand with a receptor. A new scoring algorithm is presented that estimates the binding affinity of a protein-ligand complex given a three-dimensional structure. The method, LISA (Ligand Identification Scoring Algorithm), uses an empirical scoring function to describe the binding free energy. Interaction terms have been designed to account for van der Waals (VDW) contacts, hydrogen bonding, desolvation effects and metal chelation to model the dissociation equilibrium constants using a linear model. Atom types have been introduced to differentiate the parameters for VDW, H-bonding interactions and metal chelation between different atom pairs. A training set of 492 protein-ligand complexes was selected for the fitting process. Different test sets have been examined to evaluate its ability to predict experimentally measured binding affinities. By comparing with other well known scoring functions, the results show that LISA has advantages over many existing scoring functions in simulating protein-ligand binding affinity, especially metalloprotein-ligand binding affinity. Artificial Neural Network (ANN) was also used in order to demonstrate that the energy terms in LISA are well designed and do not require extra cross terms. PMID:21561101

  17. Certifying Auto-Generated Flight Code

    Science.gov (United States)

    Denney, Ewen

    2008-01-01

    Model-based design and automated code generation are being used increasingly at NASA. Many NASA projects now use MathWorks Simulink and Real-Time Workshop for at least some of their modeling and code development. However, there are substantial obstacles to more widespread adoption of code generators in safety-critical domains. Since code generators are typically not qualified, there is no guarantee that their output is correct, and consequently the generated code still needs to be fully tested and certified. Moreover, the regeneration of code can require complete recertification, which offsets many of the advantages of using a generator. Indeed, manual review of autocode can be more challenging than for hand-written code. Since the direct V&V of code generators is too laborious and complicated due to their complex (and often proprietary) nature, we have developed a generator plug-in to support the certification of the auto-generated code. Specifically, the AutoCert tool supports certification by formally verifying that the generated code is free of different safety violations, by constructing an independently verifiable certificate, and by explaining its analysis in a textual form suitable for code reviews. The generated documentation also contains substantial tracing information, allowing users to trace between model, code, documentation, and V&V artifacts. This enables missions to obtain assurance about the safety and reliability of the code without excessive manual V&V effort and, as a consequence, eases the acceptance of code generators in safety-critical contexts. The generation of explicit certificates and textual reports is particularly well-suited to supporting independent V&V. The primary contribution of this approach is the combination of human-friendly documentation with formal analysis. The key technical idea is to exploit the idiomatic nature of auto-generated code in order to automatically infer logical annotations. The annotation inference algorithm

  19. Science inquiry learning environments created by National Board Certified Teachers

    Science.gov (United States)

    Saderholm, Jon

    The purpose of this study was to discern what differences exist between the science inquiry learning environments created by National Board Certified Teachers (NBCTs) and non-NBCTs. Four research questions organized the data collection and analysis: (a) How do National Board Certified science teachers' knowledge of the nature of science differ from that of their non-NBCT counterparts? (b) How do the frequencies of student science inquiry behaviors supported by in middle/secondary learning environments created by NBCTs differ from those created by their non-NBCT counterparts? (c) What is the relationship between the frequency of students' science inquiry behaviors and their science reasoning and understanding of the nature of science? (d) What is the impact of teacher perceptions factors impacting curriculum and limiting inquiry on the existence of inquiry learning environments? The setting in which this study was conducted was middle and high schools in Kentucky during the period between October 2006 and January 2007. The population sampled for the study was middle and secondary science teachers certified to teach in Kentucky. Of importance among those were the approximately 70 National Board Certified middle and high school science teachers. The teacher sample consisted of 50 teachers, of whom 19 were NBCTs and 31 were non-NBCTs. This study compared the science inquiry teaching environments created by NBCTs and non-NBCTs along with their consequent effect on the science reasoning and nature of science (NOS) understanding of their students. In addition, it examined the relationship with these science inquiry environments of other teacher characteristics along with teacher perception of factors influencing curriculum and factors limiting inquiry. This study used a multi-level mixed methodology study incorporating both quantitative and qualitative measures of both teachers and their students. It was a quasi-experimental design using non-random assignment of

    2002-01-01

    Full Text Available Introduction Induction of labor represents initiation of uterine contractions before their spontaneous onset. The aim of the study was to establish the role of Bishop score in prediction of labor induction in routine clinical work. Material and methods The study was a prospective blind, observational one. All patients had a vaginal examination prior to induction, during which Bishop score was evaluated. The mode of induction was either intravenous infusion of oxytocin or endovaginal prostaglandins. The induction was considered successful if vaginal delivery took place within 24 hours from the onset of induction. Results There were 100 patients, and induction was successful in 74% and unsuccessful in 26%. Mean Bishop score in group A was 5.65 (SD 1.40, 95% CI 5.27 - 6.03, and in group B 4.15 (SD 1.04, 95% CI 3.66 - 4.63 (p < 0.01. Statistical analysis of the area under the ROC curve showed that Bishop score is a good and reliable predictor of the outcome of labor induction (0.816, 95% CI od 0.710 - 0.896, with the best statistical performances at the cut-off value of 5 (sensitivity 65.5% specificity 95%, PPV 97.3%, NPV 50%. Conclusion In our study Bishop score proved to be a reliable and good method for prediction of the outcome of pregnancy if a single, experienced operator evaluates it, with best statistical performances at the cut-off value more than 5 (sensitivity 65.5%, specificity 95%, PPV 97.3%, NPV 50%. The next step would be introduction of more operators, of different skills and experience and subsequent further testing of the method in different conditions.

    A series of reference materials intended for use as activation or fission monitors for neutron fluence rate measurements has been prepared by the Joint Research Centre of the European Commission. Certification has been carried out by expert European laboratories and distribution of the certified reference materials (CRMs) is through the BCR programme of the Commission. The list (18 CRMs) includes materials to cover the complete energy spectrum, and suitable for different irradiation times. Fission monitors are 238UO2 or 237NpO2 in the form of microspheres. Activation monitors are high purity metals (Ni, Cu, Al, Fe, Nb, Rh, or Ti), certified for interfering trace impurities, or dilute aluminium-based alloys, where aluminium is chosen as a suitable matrix for reducing the neutron self-shielding effect. Newly certified materials are IRMM-530R Al-0.1%Au, replacing the exhausted IRMM-530 material, used as comparator for k0-standardization, and three new Al-Co alloys (0.01-1%Co). Two others, in the process of certification are Al-0.1%Ag and Al-2%Sc for thermal and epithermal fluence rate measurements. Other candidate reference materials currently being certified are two uranium-doped glass intended for dosimetry by the fission-track technique. (author)

    Full Text Available   "nFetal biophysical profile scoring is a sonographic-based method of fetal assessment first described by Manning and Platt in 1980. "nThe biophysical profile score was developed as a method to integrate real-time observations of the fetus and his/her intrauterine environment in order to more comprehensively assess the fetal condition. These findings must be evaluated in the context of maternal/fetal history (i.e., chronic hypertension, post-dates, intrauterine growth restriction, etc, fetal structural integrity (presence or absence of congenital anomalies, and the functionality of fetal support structures (placental and umbilical cord. For example, acute asphyxia due to placental abruption may result in an absence of the acute variables of the biophysical profile score (fetal breathing movements, fetal movement, fetal tone, and fetal heart rate reactivity with a normal amniotic fluid volume. With post maturity the asphyxial event may be intermittent and chronic resulting in a decrease in amniotic fluid volume, but with the acute variables remaining normal. "nWhile the 5 components of the biophysical profile score have remained unchanged since 1980 (Manning, 1980, the definitions of a normal and abnormal parameter have evolved with increasing experience. "nIn 1984 the definition of oligohydramnios was increased from < 1cm pocket of fluid to < 2.0 x 1.0 cm pocket. Oligohydramnios is now defined as a pocket of amniotic fluid < 2.0 x 2.0 cm (Manning, 1995a "nIf the four ultrasound variables are normal, the accuracy of the biophysical profile score was not found to be significantly improved by adding the non-stress test. As a result, in 1987 the profile score was modified to incorporate the non-stress test only when one of the ultrasound variables was abnormal (Manning 1987. Table 1 outlines the current definitions for quantifying a variable as present or absent. "nEach of the 5 components of the biophysical profile score does not have equal

  19. Interpreting force concept inventory scores: Normalized gain and SAT scores

    Directory of Open Access Journals (Sweden)

    Jeffrey J. Steinert

    2007-05-01

    Full Text Available Preinstruction SAT scores and normalized gains (G on the force concept inventory (FCI were examined for individual students in interactive engagement (IE courses in introductory mechanics at one high school (N=335 and one university (N=292 , and strong, positive correlations were found for both populations ( r=0.57 and r=0.46 , respectively. These correlations are likely due to the importance of cognitive skills and abstract reasoning in learning physics. The larger correlation coefficient for the high school population may be a result of the much shorter time interval between taking the SAT and studying mechanics, because the SAT may provide a more current measure of abilities when high school students begin the study of mechanics than it does for college students, who begin mechanics years after the test is taken. In prior research a strong correlation between FCI G and scores on Lawson’s Classroom Test of Scientific Reasoning for students from the same two schools was observed. Our results suggest that, when interpreting class average normalized FCI gains and comparing different classes, it is important to take into account the variation of students’ cognitive skills, as measured either by the SAT or by Lawson’s test. While Lawson’s test is not commonly given to students in most introductory mechanics courses, SAT scores provide a readily available alternative means of taking account of students’ reasoning abilities. Knowing the students’ cognitive level before instruction also allows one to alter instruction or to use an intervention designed to improve students’ cognitive level.

    2014-02-01

    Full Text Available Introduction: Eligible residents during their fourth postgraduate year (PGY-4 of emergency medicine (EM residency training who seek specialty board certification in emergency medicine may take the American Osteopathic Board of Emergency Medicine (AOBEM Part 1 Board Certifying Examination (AOBEM Part 1. All residents enrolled in an osteopathic EM residency training program are required to take the EM Resident In-service Examination (RISE annually. Our aim was to correlate resident performance on the RISE with performance on the AOBEM Part 1. The study group consisted of osteopathic EM residents in their PGY-4 year of training who took both examinations during that same year. Methods: We examined data from 2009 to 2012 from the National Board of Osteopathic Medical Examiners (NBOME. The NBOME grades and performs statistical analyses on both the RISE and the AOBEM Part 1. We used the RISE exam scores, as reported by percentile rank, and compared them to both the score on the AOBEM Part 1 and the dichotomous outcome of passing or failing. A receiver operating characteristic (ROC curve was generated to depict the relationship. Results: We studied a total of 409 residents over the 4-year period. The RISE percentile score correlated strongly with the AOBEM Part 1 score for residents who took both exams in the same year (r¼0.61, 95% confidence interval [CI] 0.54 to 0.66. Pass percentage on the AOBEM Part 1 increased by resident percent decile on the RISE from 0% in the bottom decile to 100% in the top decile. ROC analysis also showed that the best cutoff for determining pass or fail on the AOBEM Part 1 was a 65th percentile score on the RISE. Conclusion: We have shown there is a strong correlation between a resident’s percentile score on the RISE during their PGY-4 year of residency training and first-time success on the AOBEM Part 1 taken during the same year. This information may be useful for osteopathic EM residents as an indicator as to how well

    In 2010 the Salt Lake Valley Health Department conducted a pilot of an announced inspection program utilizing a randomized assignment of restaurants to an intervention group with announced inspections and a control group that remained on the usual schedule of unannounced inspections. After adjusting for food type, visible kitchen, outside quality assurance, season, and standardized inspector, significant reductions were found in the odds ratios of personal hygiene (adjusted odds ratios [aOR] = 0.11, p = .00) and equipment cleanliness (aOR = 0.19, p = .00) violations. In the models for the control group, none of the odds ratios were statistically different from one, indicating no change in the postintervention time period as compared to the preintervention period.

  4. Certifying qubit operations below the fault tolerance threshold

    2016-01-01

    Quantum information processors promise fast algorithms for problems inaccessible to classical computers. But since qubits are noisy and error-prone, they will depend on fault-tolerant quantum error correction (FTQEC) to compute reliably. Quantum error correction can protect against general noise if -- and only if -- the error in each physical qubit operation is smaller than a certain threshold. The threshold for general errors is quantified by their diamond norm. Until now, qubits have been assessed primarily by randomized benchmarking (RB), which reports a different "error rate" that is not sensitive to all errors, cannot be compared directly to diamond norm thresholds, and cannot efficiently certify a qubit for FTQEC. We use gate set tomography (GST) to completely characterize the performance of a trapped-Yb$^+$-ion qubit and certify it rigorously as suitable for FTQEC by establishing that its diamond norm error rate is less than $6.7\\times10^{-4}$ with $95\\%$ confidence.

    2005-07-01

    Measurement of trace elements is playing a vital role in industries and various sectors of science and technology including semiconductors, food, health and environmental sectors. In most of the cases a small error in measurement can vitiate all the measures taken for quality control and management. Many decisions regarding the suitability of material/products are based on the analysis. To reduce or eliminate the rejection rate of the products, accurate and reliable measurements are needed which can be achieved by the use of certified reference materials (CRMs). Their use in calibration of analytical equipments and validation of test methods ensures high quality in measurements and it provides traceability to the measurement data with national/international measurement systems (SI unit) also. In the present scenario of globalization of economy, use of certified reference materials (CRMs) in measurements is essential for global acceptance of products and test reports. Their use fulfil a mandatory requirement of international quality systems (ISO 9000, ISO/IEC standard 17025) including our national accreditation body, National Accreditation Board for Testing and Calibration Laboratories (NABL), World Trade Organization (WTO) etc. International manufacturers of CRMs are meeting most of the requirement of CRMs of the country. To meet the demand of CRMs indigenously, the National Physical Laboratory, India initiated a national programme on preparation and dissemination of certified reference materials.

    International Nuclear Information System (INIS)

    The REIMEP-22 inter-laboratory comparison aimed at determining the production date of a uranium certified test sample (i.e. the last chemical separation date of the material). Participants in REIMEP-22 on ''U Age Dating - Determination of the production date of a uranium certified test sample'' received one low-enriched 20 mg uranium sample for mass spectrometry measurements and/or one 50 mg uranium sample for a-spectrometry measurements, with an undisclosed value for the production date. They were asked to report the isotope amount ratios n(230Th)/n(234U) for the 20 mg uranium sample and/or the activity ratios A(230Th)/A(234U) for the 50 mg uranium sample in addition to the calculated production date of the certified test samples with its uncertainty. Reporting of the 231Pa/235U ratio and the respective calculated production date was optional. Eleven laboratories reported results in REIMEP-22. Two of them reported results for both the 20 mg and 50 mg uranium certified test samples. The measurement capability of the participants was assessed against the independent REIMEP-22 reference value by means of z- and zeta-scores in compliance with ISO 13528:2005. Furthermore a performance assessment criterion for acceptable uncertainty was applied to evaluate the participants' results. In general, the REIMEP-22 participants' results were satisfactory. This confirms the analytical capabilities of laboratories to determine accurately the age of uranium materials with low amount of ingrown thorium (young certified test sample). The Joint Research Centre of the European Commission (EC-JRC) organised REIMEP-22 in parallel to the preparation and certification of a uranium reference material certified for the production date (IRMM-1000a and IRMM-1000b).

    Irons, Jonathan; Schmucker, Martin

    2004-06-01

    Publishers of sheet music are generally reluctant in distributing their content via the Internet. Although online sheet music distribution's advantages are numerous the potential risk of Intellectual Property Rights (IPR) infringement, e.g. illegal online distributions, disables any innovation propensity. While active protection techniques only deter external risk factors, additional technology is necessary to adequately treat further risk factors. For several media types including music scores watermarking technology has been developed, which ebeds information in data by suitable data modifications. Furthermore, fingerprinting or perceptual hasing methods have been developed and are being applied especially for audio. These methods allow the identification of content without prior modifications. In this article we motivate the development of watermarking and fingerprinting technologies for sheet music. Outgoing from potential limitations of watermarking methods we explain why fingerprinting methods are important for sheet music and address potential applications. Finally we introduce a condept for fingerprinting of sheet music.

    Full Text Available Abstract Background Mesothelioma is a highly fatal cancer that is caused by exposure to asbestos fibres. In many populations, the occurrence of mesothelioma is monitored with the use of mortality data from death certification. We examine certified causes of death of patients who have been diagnosed with mesothelioma, and assess the validity of death certification data as a proxy for mesothelioma incidence. Methods We extracted mesothelioma registrations in the South East of England area between 2000 and 2004 from the Thames Cancer Registry database. We retained for analysis 2200 patients who had died at the time of analysis, after having excluded seven dead cases where the causes of death were not known to the cancer registry. The 2200 deaths were classified hierarchically to identify (1 mesothelioma deaths, (2 deaths certified as lung cancer deaths or (3 deaths from unspecified cancer, and (4 deaths from other causes. Results 87% of the patients had mesothelioma mentioned on the death certificate. 6% had no mention of mesothelioma but included lung cancer as a cause of death. Another 6% had no mention of mesothelioma or lung cancer, but included an unspecified cancer as a cause of death. Lastly, 2% had other causes of death specified on the death certificate. Conclusion This analysis suggests that official mortality data may underestimate the true occurrence of mesothelioma by around 10%.

    International Nuclear Information System (INIS)

    Nuclear magnetic resonance spectroscopy was found suitable for the identification of individual colours, for distinguishing individual colours from colour mixtures, for the identification and semi-quantitative determination of the individual colours in mixtures and for proofs of the adulteration of certified colours adding noncertified colours. The method is well suited for observing the purity of colours and may also be used as the control method in the manufacture of colours and in assessing their stability and their resistance to increased temperature and light.

    Full Text Available It is generally easier to predict defaults accurately if a large data set (including defaults is available for estimating the prediction model. This puts not only small banks, which tend to have smaller data sets, at disadvantage. It can also pose a problem for large banks that began to collect their own historical data only recently, or banks that recently introduced a new rating system. We used a Bayesian methodology that enables banks with small data sets to improve their default probability. Another advantage of the Bayesian method is that it provides a natural way for dealing with structural differences between a bank’s internal data and additional, external data. In practice, the true scoring function may differ across the data sets, the small internal data set may contain information that is missing in the larger external data set, or the variables in the two data sets are not exactly the same but related. Bayesian method can handle such kind of problem.

  8. Safe to Fly: Certifying COTS Hardware for Spaceflight

    2011-01-01

    Providing hardware for the astronauts to use on board the Space Shuttle or International Space Station (ISS) involves a certification process that entails evaluating hardware safety, weighing risks, providing mitigation, and verifying requirements. Upon completion of this certification process, the hardware is deemed safe to fly. This process from start to finish can be completed as quickly as 1 week or can take several years in length depending on the complexity of the hardware and whether the item is a unique custom design. One area of cost and schedule savings that NASA implements is buying Commercial Off the Shelf (COTS) hardware and certifying it for human spaceflight as safe to fly. By utilizing commercial hardware, NASA saves time not having to develop, design and build the hardware from scratch, as well as a timesaving in the certification process. By utilizing COTS hardware, the current detailed certification process can be simplified which results in schedule savings. Cost savings is another important benefit of flying COTS hardware. Procuring COTS hardware for space use can be more economical than custom building the hardware. This paper will investigate the cost savings associated with certifying COTS hardware to NASA s standards rather than performing a custom build.

    Employees in aged care are at high risk of workplace aggression. Research rarely examines the individual and contextual antecedents of aggression for specific types of workers within these settings, such as nurses and certified nursing assistants (CNAs). The study aimed to explore characteristics of the job demands-resources model (JD-R), negative affectivity (NA) and demographics related to workplace aggression for aged care workers. The survey study was based on 208 nurses and 83 CNAs working within aged care. Data from each group were analysed separately using ordinal regressions. Both aged care nurses and CNAs reported high rates of bullying, external emotional abuse, threat of assault and physical assault. Elements of the JD-R model and individual characteristics were related to aggression types for both groups. Characteristics of the JD-R model, NA and demographics are important in understanding the antecedents of aggression observed among aged care workers. PMID:26224217

    Full Text Available The academic achievements of students taught by under-certified primary school teachers were compared to the academic achievements of students taught by regularly certified primary school teachers.  This sample of under-certified teachers included three types of under-qualified personnel: emergency, temporary and provisionally certified teachers.  One subset of these under-certified teachers was from the national program "Teach For America (TFA."  Recent college graduates are placed by TFA where other under-qualified under-certified teachers are often called upon to work, namely, low-income urban and rural school districts. Certified teachers in this study were from accredited universities and all met state requirements for receiving the regular initial certificate to teach.  Recently hired under-certified and certified teachers (N=293 from five low-income school districts were matched on a number of variables, resulting in 109 pairs of teachers whose students all took the mandated state achievement test. Results indicate 1 that students of TFA teachers did not perform significantly different from students of other under-certified teachers, and 2 that students of certified teachers out-performed students of teachers who were under-certified.  This was true on all three subtests of the SAT 9—reading, mathematics and language arts.  Effect sizes favoring the students of certified teachers were substantial.  In reading, mathematics, and language, the students of certified teachers outperformed students of under-certified teachers, including the students of the TFA teachers, by about 2 months on a grade equivalent scale.  Students of under-certified teachers make about 20% less academic growth per year than do students of teachers with regular certification.  Traditional programs of teacher preparation apparently result in positive effects on the academic achievement of low-income primary school children.  Present

    Diagnostic criteria for postmenopausal osteoporosis using central dual-energy X-ray absorptiometry (DXA) T-scores have been widely accepted. The validity of these criteria for other populations, including premenopausal women and young men, has not been established. The International Society for Clinical Densitometry (ISCD) recommends using DXA Z-scores, not T-scores, for diagnosis in premenopausal women and men aged 20-49 yr, though studies supporting this position have not been published. We examined diagnostic agreement between DXA-generated T-scores and Z-scores in a cohort of men and women aged 20-49 yr, using 1994 World Health Organization and 2005 ISCD DXA criteria. Four thousand two hundred and seventy-five unique subjects were available for analysis. The agreement between DXA T-scores and Z-scores was moderate (Cohen\\'s kappa: 0.53-0.75). The use of Z-scores resulted in significantly fewer (McNemar\\'s p<0.001) subjects diagnosed with "osteopenia," "low bone mass for age," or "osteoporosis." Thirty-nine percent of Hologic (Hologic, Inc., Bedford, MA) subjects and 30% of Lunar (GE Lunar, GE Madison, WI) subjects diagnosed with "osteoporosis" by T-score were reclassified as either "normal" or "osteopenia" when their Z-score was used. Substitution of DXA Z-scores for T-scores results in significant diagnostic disagreement and significantly fewer persons being diagnosed with low bone mineral density.

Three radiologists independently scored 88 pairs of radiographs and tomosynthesis examinations of the chest in 60 patients with cystic fibrosis and 7 oncology patients. Radiographs were scored according to the Brasfield scoring system and tomosynthesis examinations were scored using the new scoring system. Observer agreements for the tomosynthesis score were almost perfect for the total score with square-weighted kappa >0.90, and generally substantial to almost perfect for subscores. Correlation between the tomosynthesis score and the Brasfield score was good for the three observers (Kendall's rank correlation tau 0.68, 0.77 and 0.78). Tomosynthesis was generally scored higher as a percentage of the maximum score. Observer agreements for the total score for Brasfield score were almost perfect (square-weighted kappa 0.80, 0.81 and 0.85). The tomosynthesis scoring system seems robust and correlates well with the Brasfield score. Compared with radiography, tomosynthesis is more sensitive to cystic fibrosis changes, especially bronchiectasis and mucus plugging, and the new tomosynthesis scoring system offers the possibility of more detailed and accurate scoring of disease severity.

    2015-12-01

    A problem that frequently occurs in metrology is the bias checking of data obtained by a laboratory against the specified value and uncertainty estimate given in the certificate of analysis. The measurand—a property of a certified reference material (CRM)—is supposed to be random with a normal distribution whose parameters are given by the certificate specifications. The laboratory’s data from subsequent measurements of the CRM (a CRM experiment) are summarized by the sample mean value and its uncertainty which is commonly based on a repeatability standard deviation. New confidence intervals for the lab’s bias are derived. Although they may lack intuitive appeal, those obtained by using higher order asymptotic methods, compared and contrasted in this paper, are recommended.

    Challenges of the current health system in the United States call for collaboration of health care professionals, careful utilization of resources, and greater efficiency of system processes. Innovations to the delivery of care include the introduction of the clinical nurse leader role to provide leadership at the point of care, where it is needed most. Clinical nurse leaders have demonstrated their ability to address needed changes and implement improvements in processes that impact the efficiency and quality of patient care across the continuum and in a variety of settings, including critical care. This article describes the role of the certified clinical nurse leader, their education and skill set, and outlines outcomes that have been realized by their efforts. Specific examples of how clinical nurse leaders impact critical care nursing are discussed. PMID:27487750

However, in light of the recent global financial crises, it has become extremely important for financial institutions to implement rigorous means of assessing clients seeking access to credit facilities.Research design, approach and method: Using a data sample of 10 349 observations drawn between 1992 and 2010, logistic regression models were utilised to examine the predictive performance of credit scoring systems.Main findings: A test of Goodness of fit demonstrated that credit scoring models that incorporated the Taiwan Corporate Credit Risk Index (TCRI, micro- and also macroeconomic variables possessed greater predictive power. This suggests that macroeconomic variables do have explanatory power for default credit risk.Practical/managerial implications: The originality in the study was that three models were developed to predict corporate firms’ defaults based on different microeconomic and macroeconomic factors such as the TCRI, asset growth rates, stock index and gross domestic product.Contribution/value-add: The study utilises different goodness of fits and receiver operator characteristics during the examination of the robustness of the predictive power of these factors.

  17. Interpreting the Meaning of Pain Severity Scores

    Directory of Open Access Journals (Sweden)

    Marilyn J Hodgins

    2002-01-01

    Full Text Available Poor pain management practices are generally discussed in terms of barriers associated with the patient, clinician and/or health care organization. The impact of deficiencies in the tools that are used to measure pain are seldom addressed. Three factors are discussed that complicate the measurement of pain: the nature of pain, the lack of meaning associated with scores generated by pain scales, and treatment goals that lack specificity and are not linked to patients' pain scores. The major premise presented in the present article is that the utility of pain measurement is limited because health care professionals do not have a common understanding of the meaning of scores generated by pain measurement tools, especially within the acute care setting. To address this issue, approaches to establishing instrument validity need to be broadened to include the examination of the meaning and consequences of these measurements within a specific context. Substantive improvements in pain management are unlikely to occur until criteria are identified to link explicitly the scores generated by pain measurement tools to treatment goals.

    Credit scores are the most widely used instruments to assess whether or not a person is a financial risk. Credit scoring has been so successful that it has expanded beyond lending and into our everyday lives, even to inform how insurers evaluate our health. The pervasive application of credit scoring has outpaced knowledge about why credit scores are such useful indicators of individual behavior. Here we test if the same factors that lead to poor credit scores also lead to poor health. Following the Dunedin (New Zealand) Longitudinal Study cohort of 1,037 study members, we examined the association between credit scores and cardiovascular disease risk and the underlying factors that account for this association. We find that credit scores are negatively correlated with cardiovascular disease risk. Variation in household income was not sufficient to account for this association. Rather, individual differences in human capital factors—educational attainment, cognitive ability, and self-control—predicted both credit scores and cardiovascular disease risk and accounted for ∼45% of the correlation between credit scores and cardiovascular disease risk. Tracing human capital factors back to their childhood antecedents revealed that the characteristic attitudes, behaviors, and competencies children develop in their first decade of life account for a significant portion (∼22%) of the link between credit scores and cardiovascular disease risk at midlife. We discuss the implications of these findings for policy debates about data privacy, financial literacy, and early childhood interventions. PMID:25404329

  19. Computer scoring of the Levels of Emotional Awareness Scale.

    Barchard, Kimberly A; Bajgar, Jane; Leaf, Duncan Ermini; Lane, Richard D

    2010-05-01

    The Levels of Emotional Awareness Scale (LEAS; Lane, Quinlan, Schwartz, Walker, & Zeitlan, 1990) is the most commonly used measure of differentiation and complexity in the use of emotion words and is associated with important clinical outcomes. Hand scoring the LEAS is time consuming. Existing programs for scoring open-ended responses cannot mimic LEAS hand scoring. Therefore, Leaf and Barchard (2006) developed the Program for Open-Ended Scoring (POES) to score the LEAS. In this article, we report a study in which the reliability and validity of POES scoring were examined. In the study, we used three participant types (adult community members, university students, children), three LEAS versions (paper based, computer based, and the LEAS for children), and a diverse set of criterion variables. Across this variety of conditions, the four POES scoring methods had internal consistencies and validities that were comparable to hand scoring, indicating that POES scoring can be used in clinical practice and other applied settings in which hand scoring is impractical.

  6. A study of compliance with environmental regulations of ISO 14001 certified companies in Korea.

    Science.gov (United States)

    Kwon, Dong-Myung; Seo, Min-Seok; Seo, Yong-Chil

    2002-08-01

    This article investigates the impact of ISO 14001 certification on the compliance with environmental regulations by Korean companies. The impact of ISO 14001 certification on the industry was studied through a questionnaire survey and the compliance of environmental regulations were investigated using government-released data. The motivation for an environment management system was a result of the current international situation and the need to maintain fair competition. ISO 14001 certification has been recognized as an essential strategy for industrial competition and to improve company/product recognition. The certified and non-certified companies' environmental regulation violation (ERV) rates were 3.5% and 11.6%, respectively, in 1997. In 1998, the ERV rate had an eight-time difference with 1.0% and 8.5% for certified and non-certified companies, respectively. Annual regulation violation rates were reduced from 3.5% in 1997 to 1.0% in 1998 with certified companies and from 11.6% in 1997 to 8.5% in 1998 with their non-certified counterparts, respectively. ISO 14001 certified companies showed more improvement than non-certified companies in regards to environmental performance. PMID:12369399

    Full Text Available The rapid evolution of information technologies and communications in the recent ten years has transformed developed countries into societies of information. The new technologies are in the heart of a debate in developing countries which also aim to take profit of the inheriting advantages. The daily press follows this evolution. For instance, it is transformed, and feeds in its turn, via its online editions, the wide web of digital networks. The observation of this adaptability permits to avoid the confusion between technical support (electronic tubes replace stain tubes and informative continent. Computing is built upon the contraction of the word information and the words mathematics and electronics. The confusion, at this level, should be ended. The written information, in terms of daily newspaper, supported by paper, stores all its propulsive force. The daily written press‟ past has a bright future as long as it‟s real dynamic is resuscitated. There a strong link between the information society and the delivery function of the written press (quality of delivering, it doesn‟t exist a unique function of delivering newspapers.

  15. Mediated definite delegation - Certified Grid jobs in ALICE and beyond

    International Nuclear Information System (INIS)

    Grid computing infrastructures need to provide traceability and accounting of their users’ activity and protection against misuse and privilege escalation, where the delegation of privileges in the course of a job submission is a key concern. This work describes an improved handling of Multi-user Grid Jobs in the ALICE Grid Services. A security analysis of the ALICE Grid job model is presented with derived security objectives, followed by a discussion of existing approaches of unrestricted delegation based on X.509 proxy certificates and the Grid middleware gLExec. Unrestricted delegation has severe security consequences and limitations, most importantly allowing for identity theft and forgery of jobs and data. These limitations are discussed and formulated, both in general and with respect to an adoption in line with Multi-user Grid Jobs. A new general model of mediated definite delegation is developed, allowing a broker to dynamically process and assign Grid jobs to agents while providing strong accountability and long-term traceability. A prototype implementation allowing for fully certified Grid jobs is presented as well as a potential interaction with gLExec. The achieved improvements regarding system security, malicious job exploitation, identity protection, and accountability are emphasized, including a discussion of non-repudiation in the face of malicious Grid jobs.

  16. Towards a Certified Lightweight Array Bound Checker for Java Bytecode

    Science.gov (United States)

    Pichardie, David

    2009-01-01

    Dynamic array bound checks are crucial elements for the security of a Java Virtual Machines. These dynamic checks are however expensive and several static analysis techniques have been proposed to eliminate explicit bounds checks. Such analyses require advanced numerical and symbolic manipulations that 1) penalize bytecode loading or dynamic compilation, 2) complexify the trusted computing base. Following the Foundational Proof Carrying Code methodology, our goal is to provide a lightweight bytecode verifier for eliminating array bound checks that is both efficient and trustable. In this work, we define a generic relational program analysis for an imperative, stackoriented byte code language with procedures, arrays and global variables and instantiate it with a relational abstract domain as polyhedra. The analysis has automatic inference of loop invariants and method pre-/post-conditions, and efficient checking of analysis results by a simple checker. Invariants, which can be large, can be specialized for proving a safety policy using an automatic pruning technique which reduces their size. The result of the analysis can be checked efficiently by annotating the program with parts of the invariant together with certificates of polyhedral inclusions. The resulting checker is sufficiently simple to be entirely certified within the Coq proof assistant for a simple fragment of the Java bytecode language. During the talk, we will also report on our ongoing effort to scale this approach for the full sequential JVM.

  17. Ripasa score: a new diagnostic score for diagnosis of acute appendicitis

    International Nuclear Information System (INIS)

    Objective: To determine the usefulness of RIPASA score for the diagnosis of acute appendicitis using histopathology as a gold standard. Study Design: Cross-sectional study. Place and Duration of Study: Department of General Surgery, Combined Military Hospital, Kohat, from September 2011 to March 2012. Methodology: A total of 267 patients were included in this study. RIPASA score was assessed. The diagnosis of appendicitis was made clinically aided by routine sonography of abdomen. After appendicectomies, resected appendices were sent for histopathological examination. The 15 parameters and the scores generated were age (less than 40 years = 1 point; greater than 40 years = 0.5 point), gender (male = 1 point; female = 0.5 point), Right Iliac Fossa (RIF) pain (0.5 point), migration of pain to RIF (0.5 point), nausea and vomiting (1 point), anorexia (1 point), duration of symptoms (less than 48 hours = 1 point; more than 48 hours = 0.5 point), RIF tenderness (1 point), guarding (2 points), rebound tenderness (1 point), Rovsing's sign (2 points), fever (1 point), raised white cell count (1 point), negative urinalysis (1 point) and foreign national registration identity card (1 point). The optimal cut-off threshold score from the ROC was 7.5. Sensitivity analysis was done. Results: Out of 267 patients, 156 (58.4%) were male while remaining 111 patients (41.6%) were female with mean age of 23.5 +- 9.1 years. Sensitivity of RIPASA score was 96.7%, specificity 93.0%, diagnostic accuracy was 95.1%, positive predictive value was 94.8% and negative predictive value was 95.54%. Conclusion: RIPASA score at a cut-off total score of 7.5 was a useful tool to diagnose appendicitis, in equivocal cases of pain. (author)

  18. Evaluation procedure for simulation facilities certified under 10 CFR 55: Final report

    International Nuclear Information System (INIS)

    This document describes the procedure to be followed by the NRC for the inspection of simulation facilities certified by facility licensees under 10 CFR 55. Inspections are divided into four major areas based on the types of evaluations conducted: (1) performance testing; (2) physical fidelity/human factors; (3) control capabilities; and (4) design, updating, modification, and testing. NRC staff representing several disciplines including license examiners, operations specialists, and human factors experts, under the direction of a team leader, will perform these inspections. A simulation facility inspection may include off-site and on-site phases. The off-site phase will consist of an examination of the simulation facility documentation and an identification of those operations and procedures which may be considered for use in performance testing during the on-site phase. In the on-site review, the staff will work closely with the facility licensee to conduct a sound and fair inspection and to evaluate the results of tests that are conducted. Inspection findings will be based upon the staff's judgment of the simulation facility's compliance with 10 CFR 55.45. Findings may range from one of ''no adverse impact on the conduct of operating tests'' through degrees of ''adverse impact requiring correction'' to ''adverse impacts so serious that the simulation facility may not be used in the conduct of operating tests until the discrepancies are corrected and the simulation facility is recertified to the NRC.''

    Full Text Available Mariam Fida,1 Salah Eldin Kassab2 1Department of Molecular Medicine, College of Medicine and Medical Sciences, Arabian Gulf University, Manama, Bahrain; 2Department of Medical Education, Faculty of Medicine, Suez Canal University, Ismailia, Egypt Purpose: The development of clinical problem-solving skills evolves over time and requires structured training and background knowledge. Computer-based case simulations (CCS have been used for teaching and assessment of clinical reasoning skills. However, previous studies examining the psychometric properties of CCS as an assessment tool have been controversial. Furthermore, studies reporting the integration of CCS into problem-based medical curricula have been limited. Methods: This study examined the psychometric properties of using CCS software (DxR Clinician for assessment of medical students (n=130 studying in a problem-based, integrated multisystem module (Unit IX during the academic year 2011–2012. Internal consistency reliability of CCS scores was calculated using Cronbach's alpha statistics. The relationships between students' scores in CCS components (clinical reasoning, diagnostic performance, and patient management and their scores in other examination tools at the end of the unit including multiple-choice questions, short-answer questions, objective structured clinical examination (OSCE, and real patient encounters were analyzed using stepwise hierarchical linear regression. Results: Internal consistency reliability of CCS scores was high (α=0.862. Inter-item correlations between students' scores in different CCS components and their scores in CCS and other test items were statistically significant. Regression analysis indicated that OSCE scores predicted 32.7% and 35.1% of the variance in clinical reasoning and patient management scores, respectively (P<0.01. Multiple-choice question scores, however, predicted only 15.4% of the variance in diagnostic performance scores (P<0.01, while

  1. Are they the same? Retrofitting 1 g sample data to certified 10 g sample characterization

    International Nuclear Information System (INIS)

    The National Institute of Standards and Technology Standard Reference Material 4357 (ocean sediment) was certified for anthropogenic radionuclides at ≥10 g sample size. However, the Aldermaston Weapons Establishment used a 1 g sample size that resulted in a highly skewed 239Pu + 240Pu alpha spectrometry measurement distribution that was outside the certified tolerance range for 10 g samples. This study evaluates the equivalence of 1 g sample results and those from 10 g samples used for certification. By re-batching the AWE 1 g results into simulated 10 g results, it was found that the AWE results were consistent with the certified plutonium activity for SRM 4357. (author)

  3. Exploring the meaning of practicing classroom inquiry from the perspectives of National Board Certified Science Teachers

    Science.gov (United States)

    Karaman, Ayhan

    Inquiry has been one of the most prominent terms of the contemporary science education reform movement (Buck, Latta, & Leslie-Pelecky, 2007; Colburn, 2006; Settlage, 2007). Practicing classroom inquiry has maintained its central position in science education for several decades because science education reform documents promote classroom inquiry as the potential savior of science education from its current problems. Likewise, having the capabilities of teaching science through inquiry has been considered by National Board for Professional Teaching Standards [NBPTS] as one of the essential elements of being an accomplished science teacher. Successful completion of National Board Certification [NBC] assessment process involves presenting a clear evidence of enacting inquiry with students. Despite the high-profile of the word inquiry in the reform documents, the same is not true in schools (Crawford, 2007). Most of the science teachers do not embrace this type of approach in their everyday teaching practices of science (Johnson, 2006; Luera, Moyer, & Everett, 2005; Smolleck, Zembal-Saul, & Yoder, 2006; Trumbull, Scarano, & Bonney, 2006). And the specific meanings attributed to inquiry by science teachers do not necessarily match with the original intentions of science education reform documents (Matson & Parsons, 2006; Wheeler, 2000; Windschitl, 2003). Unveiling the various meanings held by science teachers is important in developing better strategies for the future success of science education reform efforts (Jones & Eick, 2007; Keys & Bryan, 2001). Due to the potential influences of National Board Certified Science Teachers [NBCSTs] on inexperienced science teachers as their mentors, examining inquiry conceptions of NBCSTs is called for. How do these accomplished practitioners understand and enact inquiry? The purpose of this dissertation research study was twofold. First, it investigated the role of NBC performance assessment process on the professional development

  6. Prediction of true test scores from observed item scores and ancillary data.

    Science.gov (United States)

    Haberman, Shelby J; Yao, Lili; Sinharay, Sandip

    2015-05-01

    In many educational tests which involve constructed responses, a traditional test score is obtained by adding together item scores obtained through holistic scoring by trained human raters. For example, this practice was used until 2008 in the case of GRE(®) General Analytical Writing and until 2009 in the case of TOEFL(®) iBT Writing. With use of natural language processing, it is possible to obtain additional information concerning item responses from computer programs such as e-rater(®). In addition, available information relevant to examinee performance may include scores on related tests. We suggest application of standard results from classical test theory to the available data to obtain best linear predictors of true traditional test scores. In performing such analysis, we require estimation of variances and covariances of measurement errors, a task which can be quite difficult in the case of tests with limited numbers of items and with multiple measurements per item. As a consequence, a new estimation method is suggested based on samples of examinees who have taken an assessment more than once. Such samples are typically not random samples of the general population of examinees, so that we apply statistical adjustment methods to obtain the needed estimated variances and covariances of measurement errors. To examine practical implications of the suggested methods of analysis, applications are made to GRE General Analytical Writing and TOEFL iBT Writing. Results obtained indicate that substantial improvements are possible both in terms of reliability of scoring and in terms of assessment reliability. PMID:25773314

    2015-01-01

    The goal of the present research is to investigate and analyze possible peculiarities of the psychological state of cancer patients undergoing treatment. Scores characterizing the trait and state anxiety were acquired using the Integrative Anxiety Test from four groups: adults with no appreciable disease, pregnant women, cancer patients examined during the specific antitumor treatment, and cancer patients brought into lasting clinical remission. Statistical analysis of the testing results revealed the bimodal type of the distribution of scores. The only statistically significant exception was the distribution of the state anxiety scores in cancer patients undergoing treatment that was clearly unimodal. PMID:26176239

Using 1.5 as the cutoff, there was no significant difference between AAC and CAC results by the expert examiner (kappa = 0.756, P = 0.000 or the non-expert examiner (kappa = 0.831, P = 0.000. Evaluation of small bowel cleanliness using AAC took 15-30 min, and evaluation using CAC took about 2-3 min. The overall adequacy assessment (OAA using the AAC was not significantly different between the two examiners (χ2 = 0.586, P = 0.444. There were also no significant differences between the OAA using the AAC and the OAA using the CAC by the expert examiner (χ2 = 1.730, P = 0.188 or the non-expert examiner (χ2 = 1.124, P = 0.289. Conclusion: Both of these scores for assessment of small bowel cleanliness can be useful in clinical practice, but the CAC is simpler to use.

  16. Determination of hexavalent chromium in plastic certified reference materials by X-ray absorption fine structure analysis

    Ohata, Masaki; Matsubayashi, Nobuyuki

    X-ray absorption fine structure (XAFS) analysis with transmission mode was used to determine the percentages of hexavalent chromium {Cr(VI)} in total Cr in plastic certified reference materials (CRMs). Cr-K edge X-ray absorption near-edge structure (XANES) spectra were observed and the normalized pre-edge peaks of the spectrum where absorption data was summed was acquired for the determination of Cr(VI). Examination of different number of data point and range of photon energy for summed absorption of the pre-edge peak resulted in reproducible absorption data, though the measurements were carried out at different beam time and beam line. The concentrations of Cr(VI) in the plastic CRMs were also estimated from both the certified value of total Cr and the determined percentage of Cr(VI). The analytical procedure and the estimated concentrations can be useful for the determination of Cr(VI) in plastics with respect to RoHS (restriction of the use of hazardous substances in electrical and electronics equipment) directive.

    2015-12-01

    Full Text Available Introduction: Assessment of medical students’ knowledge in clinical settings is complex yet essential to the learning process. Clinical clerkships use various types of written examinations to objectively test medical knowledge within a given discipline. Within emergency medicine (EM, a new national standardized exam was developed to test medical knowledge in this specialty. Evaluation of the psychometric properties of a new examination is an important issue to address during test development and use. Studies have shown that student performance on selected standardized exams will reveal students’ strengths and/or weaknesses, so that effective remedial efforts can be implemented. Our study sought to address these issues by examining the association of scores on the new EM national exam with other standardized exam scores. Methods: From August 2011 to April 2013, average National EM M4 examination scores of fourthyear medical students taken at the end of a required EM clerkship were compiled. We examined the correlation of the National EM M4 examination with the scores of initial attempts of the United States Medical Licensing Exam (USMLE Step 1 and Step 2 Clinical Knowledge (CK examinations. Correlation coefficients and 95% confidence intervals of correlation coefficients are reported. We also examined the association between the national EM M4 examination score, final grades for the EM rotation, and USMLE Step 1 and Step 2 CK scores. Results: 133 students were included in the study and achieved a mean score of 79.5 SD 8.0 on the National EM M4 exam compared to a national mean of 79.7 SD 3.89. The mean USMLE Step 1 score was 226.8 SD 19.3. The mean USMLE Step 2 CK score was 238.5 SD 18.9. National EM M4 examination scores showed moderate correlation with both USMLE Step 1 (mean score=226.8; correlation coefficient=0.50; 95% CI [0.28-0.67] and USMLE Step 2 CK (mean score=238.5; correlation coefficient=0.47; 95% CI [0.25-0.65].

    Most of the benchmark studies on docking-scoring methods reported in the last decade conclude that no single scoring function performs well across different protein targets. In this study a comparison of thirteen commonly used force field and empirical scoring functions as implemented in DOCK, AMMOS, X-Score and FRED is carried out on five proteins with diverse binding pockets. The performance is analyzed in relation to the physicochemical properties of the binding sites. The solvation effects are considered via the Generalized Born/Surface Area (GBSA) solvation method for one of the assessed scoring functions. We examined the ability of these scoring functions to discriminate between active and inactive compounds over receptor-based focused libraries. Our results demonstrated that the employed here empirical scoring functions were more appropriate for the pocket of predominant hydrophobic nature while the force field scoring functions performed better on the mixed or polar pockets.

  8. Electrothermal atomic absorption spectrometric determination of vanadium in extracts of soil and sewage sludge certified reference materials after fractionation by means of the Communities Bureau of Reference modified sequential extraction procedure

    International Nuclear Information System (INIS)

    A modified three-step sequential extraction procedure proposed by the Commission of European Communities Bureau of Reference (BCR) was applied to certified reference materials of three different soil groups (rendzina, luvisol, cambisol) and sewage sludge of different composition originating from a municipal water treatment plant in order to assess potential mobility and the distribution of vanadium in the resulting fractions. Analysis of the extracts was carried out by electrothermal atomic absorption spectrometry with Zeeman background correction using transversely heated graphite atomizers. Extracts showed significant matrix interferences which were overcome by the standard addition technique. The original soil and sludge certified reference materials (CRMs) and the extraction residue from the sequential extraction were decomposed by a mixture of HNO3-HClO4-HF in an open system. The content of V determined after decomposition of the samples was in very good agreement with the certified total values. The accuracy of the sequential extraction procedure was checked by comparing the sum of the vanadium contents in the three fractions and in the extraction residue with the certified total content of V. The amounts of vanadium leached were in good correlation with the certified total contents of V in the CRMs of soils and sewage sludge. In the soils examined, vanadium was present almost entirely in the mineral lattice, while in the sewage sludge samples 9-14% was found in the oxidizable and almost 25% in the reducible fractions. The recovery ranged from 93-106% and the precision (RSD) was below 10%

    Full Text Available AIM: To compare Greek stroke score with available previous two stroke scores for the diagnosis of cerebral ischemia and hemorrhage in acute stroke patients, and validate the Greek stroke score. SETTING: A tertiary hospital in India. MATERIALS AND METHODS: In a prospective study acute stroke patients were evaluated with Greek stroke score, Allen score and Siriraj stroke score. Comparability (Kappa Statistics and validity (sensitivity, specificity, negative predictive value and positive predictive value of the Greek stroke score and previous scores were tested. RESULT: Out of the 91 patients enrolled in the study, 47 patients had cerebral infarction and 44 patients had hemorrhage by CT scan. Allen score was uncertain / equivocal in 39 patients, Siriraj Stroke score in 22 and Greek stroke score in 47 patients. Sensitivity, Specificity, positive predictive value, negative predictive value for Allen score were 0.5(95% CI:0.34,0.58, 0.94(95% CI:0.86,0.98, 0.81(95% CI:0.56,0.95, 0.78(95% CI: 0.71,0.81 for Siriraj score were 0.75(95% CI: 0.63,0.84, 0.81(95% CI: 0.71,0.89, 0.77(95% CI: 0.65,0.86, 0.78(95% CI 0.69,0.86 and for Greek Score were 0.42(95% CI: 0.23,0.53, 0.93(95% CI: 0.87,0.98, 0.71(95% CI:0.39,0.91, 0.81(95% CI:0.75,0.85 respectively. Greek stroke score was compared with previous scores using kappa statistics which revealed substantial strength of agreement between the Allen Score for certain results. CONCLUSION: The overall comparability of Greek stroke score and Allen score was better as compared to Greek stroke score and Siriraj stroke score. Greek Stroke score was more specific in diagnosing hemorrhage as compared to Siriraj score. However, all these stroke scores lack accuracy hence could not be applied safely to guide the physician in management of stroke.

    2002-07-01

    This study proposes a model linking firm motivations for seeking ISO 14001 certification to the effectiveness of three major components of an environmental management system (EMS)--environmental policy, the assessment of environmental aspect and impacts, and management review. The relationship of these EMS components with a self-reported measure of environmental performance is also examined. From a sample of 29 ISO 14001 certified facilities in Hong Kong (of 71 total certifications at the time the data was collected), it was found that motivations to enhance firm reputation are positively related to perceptions of the effectiveness of the policy statement. Motivations for reputation enhancement and cost reduction were positively related to perceptions of EMS effectiveness in assessing environmental aspects and impacts. The effectiveness of the methodology for identifying environmental aspects and impacts was also found to be positively related to improved environmental performance. PMID:12357656

    Full Text Available Background. A new public long-term care (LTC insurance was launched in 2000 in Japan. However, there have been few studies involving factors that increase LTC costs of demented subjects; no follow-up studies involving the Government-Certified Index (GCI and requisite costs related to the causes of dementia. Method. An epidemiological survey was conducted in a rural area in Japan in 1999, and 271 subjects were diagnosed as dementia patients. Age, sex, mini-mental state examination, clinical dementia rating, activity of daily living, causes of dementia, and coexisting physical disease were confirmed. After the LTC insurance has been launched, we tracked the GCI stages and payment amounts every month for 8 years. Result. 209 subjects were certified to be eligible for LTC insurance; however, 13 did not receive any payment. Only 49 out of 209 were alive after the follow-up period. The most common cause of dementia was Alzheimer’s disease (AD, followed by vascular dementia (VaD. There was no significant difference between the mortality rates of the two groups. VaD subjects required higher costs than AD subjects in the total certified period and in GCI stage 5. Conclusion. Our results indicate that causes of dementia can have an impact on the requisite costs for the LTC insurance.

  15. Reproducibility of scoring emphysema by HRCT

    International Nuclear Information System (INIS)

    Purpose: We evaluated the reproducibility of three visual scoring methods of emphysema and compared these methods with pulmonary function tests (VC, DLCO, FEV1 and FEV%) among farmer's lung patients and farmers. Material and Methods: Three radiologists examined high-resolution CT images of farmer's lung patients and their matched controls (n=70) for chronic interstitial lung diseases. Intraobserver reproducibility and interobserver variability were assessed for three methods: severity, Sanders' (extent) and Sakai. Pulmonary function tests as spirometry and diffusing capacity were measured. Results: Intraobserver -values for all three methods were good (0.51-0.74). Interobserver varied from 0.35 to 0.72. The Sanders' and the severity methods correlated strongly with pulmonary function tests, especially DLCO and FEV1. Conclusion: The Sanders' method proved to be reliable in evaluating emphysema, in terms of good consistency of interpretation and good correlation with pulmonary function tests

    In this paper we examine the possibility of using the standard Kruskal-Wallis (KW) rank test in order to evaluate whether the distribution of efficiency scores resulting from Data Envelopment Analysis (DEA) is independent of the input (or output) mix of the observations. Since the DEA frontier is...... estimated, many standard assumptions for evaluating the KW test statistic are violated. Therefore, we propose to explore its statistical properties by the use of simulation studies. The simulations are performed conditional on the observed input mixes. The method, unlike existing approaches in the...... assumption of mix independence is rejected the implication is that it, for example, is impossible to determine whether machine intensive project are more or less efficient than labor intensive projects....

  19. Provably Secure Self-certified Multi-proxy Signature with Message Recovery

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available Signature schemes with message recovery based on self-certified public keys can reduce the amount of communications and computations, since the signature verification, the public key authentication and the message recovery are simultaneously carried out in a single logical step. Integrating self-certified public-key systems and the message recovery signature schemes, in 2009, Wu et al. proposed two multi-proxy signatures based on the discrete logarithms over a finite field and the elliptic curve discrete logarithms. The proxy warrant revision attacks are proposed, and it will show that Wu et al.’s schemes can not resist the proxy warrant revision attacks by either the proxy group or the original signer. Further, a formal model of self-certified multi-proxy signature and a new scheme are proposed. The proposed scheme is provably secure in the random oracle model.

    Certified reference materials (CRMs) are essential tools to guarantee the metrological traceability of measurement results to the International System of Units (SI), which means the accuracy and comparability of results over time and space. In the pharmaceutical area, only a few CRMs are available and the use of (non-certified) reference materials is a much more common practice. In this paper, the studies on a new candidate CRM of sodium diclofenac based on the ISO Guides 34:2009 and 35:2005 are described. The project steps included characterization, homogeneity test, stability studies, and uncertainties estimation. In the characterization, the mass fractions of organic, inorganic, and volatile impurities were determined, and the results were cross-checked by independent reference methods or interlaboratorial study. The API mass fraction was calculated by mass balance and cross-checked by quantitative proton nuclear magnetic resonance (¹H qNMR). The paper also presents a Monte Carlo simulation to estimate the measurement uncertainty as an approach to validate the GUM results in ¹H qNMR. The homogeneity between batch units was verified, and the candidate CRM stability under transport and storage conditions was evaluated in short- and long-term stability studies. The CRM certified property value and corresponding expanded uncertainty, obtained from the combined standard uncertainty multiplied by the coverage factor (k=2), for a confidence level of 95%, was (999.76+0.10) mg g⁻¹.

  1. The value of CT score in predicting surgical methods and difficulty of hepatic cystic echinococcosis

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of MSCT scores on surgery method selection and its difficulty estimation for hepatic cystic echinococcosis. Methods: Based on the CT features of hepatic cystic echinococcosis (HCE), an integral system including 7 items was established. Images of preoperative CT examination performed on 71 cases of hepatic cystic echinococcosis were retrospectively analyzed by the integral system and compared with actual surgical. Total 93 cystic lesions were divided into 3 groups based on CT scores: Group A suitable for total cystectomy (0 to 5 score), Group B suitable for subtotal cystectomy (6 to 10 score), and Group C suitable forendocystectomy ( ≥ 11 scores, or 4 score in one item), Spearman rank correlation was used to analyze the relationship between WHO classification of cystic echinococcosis and actual surgery methods, the relationship between operation mode forecasted by CT scores and actual surgery methods, the relationship between vessel scores of cyst and actual surgery methods, and that between biliary score of cyst and actual surgery methods. Fisher exact test and Chi-square test were used to evaluate the incidence of residual cavity in patients with different biliary scores. Results: Thirty nine cysts got 0 to 5 scores, 45 cysts got 6 to 10 scores and 9 cysts got more than 10 scores. Total cystectomy was performed on 30 cysts, subtotal cystectomy on 40 cysts and performed endocystectomy on 23 cysts, actually. Actual operation methods were correlated with that predicated by CT scores (r=0.741, P<0.01), and with vessels score and biliary score (r=0.587, 0.327 respectively, P<0.01). The higher the biliary score, the higher the incidence of postoperative biliary tract complications. Conclusions: Preoperative CT scoring was an easy and objective way to accurately predict the surgery methods and its difficulty for hepatic cystic echinococcosis. (authors)

  2. Measurement of Nonverbal IQ in Autism Spectrum Disorder: Scores in Young Adulthood compared to Early Childhood

    Bishop, Somer L.; Farmer, Cristan; Thurm, Audrey

    2014-01-01

    Nonverbal IQ (NVIQ) was examined in 84 individuals with ASD followed from age 2 to 19. Most adults who scored in the range of ID also received scores below 70 as children, and the majority of adults with scores in the average range had scored in this range by age 3. However, within the lower ranges of ability, actual scores declined from age 2 to 19, likely due in part to limitations of appropriate tests. Use of Vineland-II DLS scores in place of NVIQ did not statistically improve the correspondence between age 2 and age 19 scores. Clinicians and researchers should use caution when making comparisons based on exact scores or specific ability ranges within or across individuals with ASD of different ages. PMID:25239176

    2013-01-01

    High School Modeling Workshops are designed to improve high school physics teachers' understanding of physics and how to teach using the Modeling method. The basic assumption is that the teacher plays a critical role in their students' physics education. This study investigated teacher impacts on students' Force Concept Inventory scores, (FCI), with the hopes of identifying quantitative differences between teachers. This study examined student FCI scores from 18 teachers with at least a year of teaching high school physics. This data was then evaluated using a General Linear Model (GLM), which allowed for a regression equation to be fitted to the data. This regression equation was used to predict student post FCI scores, based on: teacher ID, student pre FCI score, gender, and representation. The results show 12 out of 18 teachers significantly impact their student post FCI scores. The GLM further revealed that of the 12 teachers only five have a positive impact on student post FCI scores. Given these differences among teachers it is our intention to extend our analysis to investigate pedagogical differences between them.

  11. Differences in distribution of T-scores and Z-scores among bone densitometry tests in postmenopausal women (a comparative study)

    International Nuclear Information System (INIS)

    To determine the character of T-score and Z-score value distribution in individually selected methods of bone densitometry and to compare them using statistical analysis. We examined 56 postmenopausal women with an age between 43 and 68 years with osteopenia or osteoporosis according to the WHO classification. The following measurements were made in each patient: T-score and Z-score for: 1) Stiffness index (S) of the left heel bone, USM (index). 2) Bone mineral density of the left heel bone (BMDh), DEXA (g of Ca hydroxyapatite per cm2). 3) Bone mineral density of trabecular bone of the L1 vertebra (BMDL1). QCT (mg of Ca hydroxyapatite per cm3). The densitometers used in the study were: ultrasonometer to measure heel bone, Achilles plus LUNAR, USA: DEXA to measure heel bone, PIXl, LUNAR, USA: QCT to measure the L1 vertebra, CT, SOMATOM Plus, Siemens, Germany. Statistical analysis: differences between measured values of T-scores (Z-scores) were evaluated by parametric or non-parametric methods of determining the 95 % confidence intervals (C.I.). Differences between Z-score and T-score values for compared measurements were statistically significant; however, these differences were lower for Z-scores. Largest differences in 95 % C.I., characterizing individual measurements of T-score values (in comparison with Z-scores), were found for those densitometers whose age range of the reference groups of young adults differed the most, and conversely, the smallest differences in T-score values were found when the differences between the age ranges of reference groups were smallest. The higher variation in T-score values in comparison to Z-scores is also caused by a non-standard selection of the reference groups of young adults for the QCT, PIXI and Achilles Plus densitometers used in the study. Age characteristics of the reference group for T-scores should be standardized for all types of densitometers. (author)

  19. Certifying the commons: eco-certification, privatization, and collective action

    Directory of Open Access Journals (Sweden)

    Paul Foley

    2014-06-01

    Full Text Available We examine new dynamics of privatization and collective action in common pool resource situations facilitated by the nonstate multistakeholder institutions of the Marine Stewardship Council (MSC, the global leader in sustainability certification for wild caught seafood. Through a review of the literature and two case studies of fishing cooperatives in Baja California Sur, Mexico and on Fogo Island in the Canadian Province of Newfoundland and Labrador (NL, we advance two interrelated arguments. First, certification and eco-labeling institutions privatize fisheries governance in largely unexamined ways through the injection of new forms of exclusive rights or privileges into common pool resource situations already complicated by access and property privileges, creating conditions for confusion and conflict as well as cooperation. Second, the MSC whole stock definition of sustainability places greater demands on certification clients for engaging in collective action by encouraging coordination over all social extractions from targeted fish stocks. Although rules encouraging collective action in common pool situations militate against the narrow private capture of certificate and eco-label rights, they also undermine the ability of small-scale and community-based fisheries that are embedded in larger unhealthy fishery contexts to acquire the right to the MSC stamp of sustainability. We conclude that MSC certification and eco-labeling create new institutions of private property rights and collective action, which can result in exclusionary practices, inclusionary collective action, or both. Much will depend on the specific common pool context and history of the fishery.

    Taylor, Brian T.

    2014-11-01

    Full Text Available Introduction: Several studies have attempted to demonstrate that the Thrombolysis in Myocardial Infarction (TIMI risk score has the ability to risk stratify emergency department (ED patients with potential acute coronary syndromes (ACS. Most of the studies we reviewed relied on trained research investigators to determine TIMI risk scores rather than ED providers functioning in their normal work capacity. We assessed whether TIMI risk scores obtained by ED providers in the setting of a busy ED differed from those obtained by trained research investigators. Methods: This was an ED-based prospective observational cohort study comparing TIMI scores obtained by 49 ED providers admitting patients to an ED chest pain unit (CPU to scores generated by a team of trained research investigators. We examined provider type, patient gender, and TIMI elements for their effects on TIMI risk score discrepancy. Results: Of the 501 adult patients enrolled in the study, 29.3% of TIMI risk scores determined by ED providers and trained research investigators were generated using identical TIMI risk score variables. In our low-risk population the majority of TIMI risk score differences were small; however, 12% of TIMI risk scores differed by two or more points. Conclusion: TIMI risk scores determined by ED providers in the setting of a busy ED frequently differ from scores generated by trained research investigators who complete them while not under the same pressure of an ED provider.

  4. Combination of scoring schemes for protein docking

    Directory of Open Access Journals (Sweden)

    Schomburg Dietmar

    2007-08-01

    Full Text Available Abstract Background Docking algorithms are developed to predict in which orientation two proteins are likely to bind under natural conditions. The currently used methods usually consist of a sampling step followed by a scoring step. We developed a weighted geometric correlation based on optimised atom specific weighting factors and combined them with our previously published amino acid specific scoring and with a comprehensive SVM-based scoring function. Results The scoring with the atom specific weighting factors yields better results than the amino acid specific scoring. In combination with SVM-based scoring functions the percentage of complexes for which a near native structure can be predicted within the top 100 ranks increased from 14% with the geometric scoring to 54% with the combination of all scoring functions. Especially for the enzyme-inhibitor complexes the results of the ranking are excellent. For half of these complexes a near-native structure can be predicted within the first 10 proposed structures and for more than 86% of all enzyme-inhibitor complexes within the first 50 predicted structures. Conclusion We were able to develop a combination of different scoring schemes which considers a series of previously described and some new scoring criteria yielding a remarkable improvement of prediction quality.

    The stratification score for a case-control study is the probability of disease modeled as a function of potential confounders.

The authors further show how standardization using the stratification score can be used to compare the distributions of exposures that would be found among case and control partic...

  6. [The diagnostic scores for deep venous thrombosis].

    Science.gov (United States)

    Junod, A

    2015-08-26

    Seven diagnostic scores for the deep venous thrombosis (DVT) of lower limbs are analyzed and compared. Two features make this exer- cise difficult: the problem of distal DVT and of their proximal extension and the status of patients, whether out- or in-patients. The most popular score is the Wells score (1997), modi- fied in 2003. It includes one subjective ele- ment based on clinical judgment. The Primary Care score 12005), less known, has similar pro- perties, but uses only objective data. The pre- sent trend is to associate clinical scores with the dosage of D-Dimers to rule out with a good sensitivity the probability of TVP. For the upper limb DVT, the Constans score (2008) is available, which can also be coupled with D-Dimers testing (Kleinjan). PMID:26502582

  7. Random Walk Picture of Basketball Scoring

    CERN Document Server

    Gabel, Alan

    2011-01-01

    We present evidence, based on play-by-play data from all 6087 games from the 2006/07--2009/10 seasons of the National Basketball Association (NBA), that basketball scoring is well described by a weakly-biased continuous-time random walk. The time between successive scoring events follows an exponential distribution, with little memory between different scoring intervals. Using this random-walk picture that is augmented by features idiosyncratic to basketball, we account for a wide variety of statistical properties of scoring, such as the distribution of the score difference between opponents and the fraction of game time that one team is in the lead. By further including the heterogeneity of team strengths, we build a computational model that accounts for essentially all statistical features of game scoring data and season win/loss records of each team.

    Motivation: Sequence similarity searches performed with BLAST, SSEARCH and FASTA achieve high sensitivity by using scoring matrices (e.g. BLOSUM62) that target low identity (33% identity). Adjusting the scoring matrix to reflect the identity of the homologous sequence can correct higher identity overextended alignment boundaries. In addition, the scoring matrix that produced a correct alignment could be reliably predicted based on the sequence identity seen in the original BLOSUM62 alignment....

    2013-01-01

    Starting in the early 1990s credit scoring became widespread and central in credit granting decisions. Credit scores are scalar representations of default risk. They are used, in turn, to price credit, and as a result alter household borrowing and default decisions. We build on recent work on defaultable consumer credit under asymmetric information to develop a quantitative theory of credit scores. We construct and solve a rich and quantitatively-disciplined lifecycle model of consumption in ...

  12. Motivation, test scores and economic success

    OpenAIRE

    Segal, Carmit

    2006-01-01

    This paper argues that low-stakes test scores, available in surveys, may be partially determined by test-taking motivation, which is associated with personality traits but not with cognitive ability. Therefore, such test score distributions may not be informative regarding cognitive ability distributions. Moreover, correlations, found in survey data, between high test scores and economic success may be partially caused by favorable personality traits. To demonstrate these point...

  13. Consumer credit scoring: do situational circumstances matter?

    OpenAIRE

    Avery, Robert B.; Paul S. Calem; Glenn B. Canner

    2004-01-01

    Although credit history scoring offers benefits to lenders and borrowers, failure to consider situational circumstances raises important statistical issues that may affect the ability of scoring systems to accurately quantify an individual's credit risk. Evidence from a national sample of credit reporting agency records suggests that failure to consider measures of local economic circumstances and individual trigger events when developing credit history scores can diminish the potential effec...

  14. Scoring Function Based on Weighted Residue Network

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Molecular docking is an important method for the research of protein-protein interaction and recognition. A protein can be considered as a network when the residues are treated as its nodes. With the contact energy between residues as link weight, a weighted residue network is constructed in this paper. Two weighted parameters (strength and weighted average nearest neighbors’ degree are introduced into this model at the same time. The stability of a protein is characterized by its strength. The global topological properties of the protein-protein complex are reflected by the weighted average nearest neighbors’ degree. Based on this weighted network model and these two parameters, a new docking scoring function is proposed in this paper. The scoring and ranking for 42 systems’ bound and unbounded docking results are performed with this new scoring function. Comparing the results obtained from this new scoring function with that from the pair potentials scoring function, we found that this new scoring function has a similar performance to the pair potentials on some items, and this new scoring function can get a better success rate. The calculation of this new scoring function is easy, and the result of its scoring and ranking is acceptable. This work can help us better understand the mechanisms of protein-protein interactions and recognition.

    2006-01-01

    A chain graph allows both directed and undirected edges, and contains the underlying mathematical properties of the two. An important method of learning graphical models is to use scoring criteria to measure how well the graph structures fit the data. In this paper, we present a scoring criterion for learning chain graphs based on the Kullback-Leibler distance. It is score equivalent, that is, equivalent chain graphs obtain the same score, so it can be used to perform model selection and model averaging.

    2015-09-01

    Full Text Available Objectives: To evaluate the relationship between the pass rate of the American Board of Internal Medicine (ABIM certifying exam and the characteristics of residency programs. Methods: The study used a retrospective, cross-sectional design with publicly available data from the ABIM and the Fellowship and Residency Electronic Interactive Database. All categorical residency programs with reported pass rates were included. Using univariate and multivariate, linear regression analyses, I analyzed how 69 factors (e.g., location, general information, number of faculty and trainees, work schedule, educational environment are related to the pass rate. Results: Of 371 programs, only one region had a significantly different pass rate from the other regions; however, as no other characteristics were reported in this region, I excluded program location from further analysis. In the multivariate analysis, pass rate was significantly associated with four program characteristics: ratio of full-time equivalent paid faculty to positions, percentage of osteopathic doctors, formal mentoring program, and on-site child care (OCC. Numerous factors were not associated at all, including minimum exam scores, salary, vacation days, and average hours per week. Conclusions: As shown through the ratio of full-time equivalent paid faculty to positions and whether there was a formal mentoring program, a highly supervised training experience was strongly associated with the pass rate. In contrast, percentage of osteopathic doctors was inversely related to the pass rate. Programs with OCC significantly outperformed programs without OCC. This study suggested that enhancing supervision of training programs and offering parental support may help attract and produce competitive residents.

  20. Evaluation of initial diffusion-weighted image findings in acute stroke patients using a semiquantitative score

    International Nuclear Information System (INIS)

    We evaluated the usefulness of rating diffusion-weighted images (DWI) using a semiquantitative score modified from the Alberta Stroke Programme Early CT Score (ASPECTS) to predict deterioration of neurological symptoms in patients with hyperacute ischemic stroke who had undergone thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA). We examined 22 patients with acute stroke (14 men, 8 women, mean age 72.5 years) treated with intravenous rt-PA. All were assessed using the National Institutes of Health Stroke Scale (NIHSS) and underwent emergent magnetic resonance (MR) imaging within 3 hours and 24 hours of stroke onset. Patients were divided into a deteriorated group (16 patients), in which NIHSS scores were increased after thrombolysis, and a non-deteriorated group (6 patients). We compared the DWI score, ASPECTS, and volume of hyperintense ischemic lesion on DWI (DWI volume) of the 2 groups and examined correlations between these scores and initial NIHSS score or DWI volume. The DWI score and ASPECTS tended to be lower in the deteriorated group than the non-deteriorated group. In addition, with a cutoff value ≤7, the DWI score could discriminate the deteriorated group from the non-deteriorated group with a sensitivity of 50% and specificity of 87.5%, whereas for ASPECTS, sensitivity was 50% and specificity, 81.2%. The DWI score, ASPECTS, and DWI volume had no correlation with NIHSS score but weak negative correlations with the DWI volume (P<0.01; Spearman's test). Comparing initial NIHSS score with each DWI score and DWI volume, the non-deteriorated group tended to have higher DWI scores and smaller DWI volumes than the deteriorated group, but there was no statistical difference between initial NIHSS and DWI scores. Though the DWI score was not statistically different, the threshold would be set to 6 points or above. Comparing initial DWI score with volume, patients with low DWI scores tended to show large variation in DWI volume and

  14. Random Factors in IOI 2005 Test Case Scoring

    Directory of Open Access Journals (Sweden)

    Gordon CORMACK

    2006-04-01

    Full Text Available We examine the precision with which the cumulative score from a suite of test cases ranks participants in the International Olympiad in Informatics (IOI. Our concern is the ability of these scores to reflect achievement at all levels, as opposed to reflecting chance or arbitrary factors involved in composing the test suite. Test cases are assumed to be drawn from an infinite population of similar cases; variance in standardized rank is estimated by the bootstrap method and used to compute confidence intervals which contain the hypothetical true ranking with 95% probability. We examine the relative contribution of easy (so-called fifty-percent rule cases and hard cases to the overall ranking. Empirical results based on IOI 2005 suggest that easy and hard cases are both material to the ranking, but the proportion of each is unimportant.

    Colloidal quantum dot (CQD) solar cells are solution-processed photovoltaics with broad spectral absorption tunability. Major advances in their efficiency have been made via improved CQD surface passivation and device architectures with enhanced charge carrier collection. Herein, we demonstrate a new strategy to improve further the passivation of CQDs starting from the solution phase. A cosolvent system is employed to tune the solvent polarity in order to achieve the solvation of methylammonium iodide (MAI) and the dispersion of hydrophobic PbS CQDs simultaneously in a homogeneous phase, otherwise not achieved in a single solvent. This process enables MAI to access the CQDs to confer improved passivation. This, in turn, allows for efficient charge extraction from a thicker photoactive layer device, leading to a certified solar cell power conversion efficiency of 10.6%, a new certified record in CQD photovoltaics.

  16. Metrological management evaluation based on ISO10012: an empirical study in ISO-14001-certified Spanish companies

    International Nuclear Information System (INIS)

    Environmental management systems based on the ISO 14001 standard rely strongly on metrological measurement and confirmation processes to certify the extent to which organizations monitor and improve their environmental behavior. Nevertheless, the literature lacks in studies that assess the influence of these metrological processes on the performance of environmental management in organizations, even now that the international standard ISO 10012 is already available to establish requisites and guidelines for the development of a metrological management system that is compatible with any other standardized management system. This work seeks to assess that influence through the development of an evaluation model for metrological management, which is then validated through an experimental analysis of the results obtained from the application of an audit process in 11 Spanish companies, all ISO-14001-certified and operating in different industrial sectors.

    Isotope dilution mass spectrometry and standard addition techniques were developed for the analysis of four elements (Ca, As, Cd and Pb) in a mushroom powder material. Results from the validated methods were compared to those of other national metrology institutes in the CCQM-K89 intercomparisons and the results were in excellent agreement with the reference values. The same methods were then used for the assignment of reference values to a mushroom powder Certified Reference Material (CRM). The certified values obtained for Ca, As, Cd and Pb were 1.444 ± 0.099 mg/g, 5.61 ± 0.59 mg/kg, 1.191 ± 0.079 mg/kg and 5.23 ± 0.94 mg/kg, respectively. The expanded measurement uncertainties were obtained by combining the uncertainty contributions from characterization (uchar) and between-bottle homogeneity (ubb). PMID:26212973

  18. Certified reference materials for analytical quality control in neutron activation analysis

    International Nuclear Information System (INIS)

    Analytical quality control in neutron activation analysis (NAA) requires the use of certified reference materials (CRM) in order to produce reliable analytical results. It is essential to evaluate the performance of NAA method when analyzing various sample matrices. Therefore, the CRM selected for an analysis should be suitable for the type of samples. There are many aspects such as concentration range, matrix match, sample size and uncertainty, which need to be considered when selecting a suitable CRM. Eventually, results of analysis of CRM were plotted into control charts in order to evaluate the qualify of the data. This is to ensure that the results are within the 95 % confidence interval as stipulated in the certificate of CRM. Thus, this article aims to discuss the uses of certified reference materials for quality control purposes in NAA involving various sample matrices. (author)

    Full Text Available The study intends to describe the level of certified EFL teachers’ self-assessment of their competence to teach English. A cross-sectional survey design and systematic random sampling strategy were applied to take 227 research respondents. Questionnaire and interview were used for collecting data whereas frequency, percentage and descriptive statistics were employed to analyze the data. Most respondents self-rated their abilities to teach English at ‘competent’ and ‘strongly competent’ levels. Yet, their self-rating of English teaching competence did not match up with the re-sults of teacher competence test done by the government. Accordingly, the self-assessment should be endorsed with teaching performance assessment to have more reliable data for validating EFL teachers’ self-grading abilities in English teaching practices. Key Words: self-assessment, teacher certification program, teacher standard of competence, certified EFL teachers, english teaching practices

Patients were examined with dual-source CT and were grouped according to their age, gender, CACS, and estimated SCORE risk. Coronary plaque existence and degree of stenosis were assessed with CTCA. Sensitivity, specificity, and ROC curves were analyzed. CACS was the single independent variable in estimating relative risk of critical stenosis and had superior outcome when compared with SCORE risk in logistic regression and ROC curve. Area under the ROC curve was greatest in the interval between 50-59 years. When SCORE was combined with CACS in patients with zero CACS, percentage of significant stenosis increased from 1.4% to 7.0% in patients with high or very high SCORE risk, and decreased to 0.9 % in patients with low or moderate SCORE risk. CACS combination with SCORE risk predicts coronary artery stenosis. When CACS is zero, CTCA can be performed in patients with high or very high SCORE risk. (orig.)

    There is a strong association between schooling attained and test scores in many settings. If this association is causal, one might expect that programs that increase school enrollment and attainment would also improve test scores. However, if there is self-selection into school based on expected gains, marginal children brought into school by such programs may be drawn disproportionately from ...

    2016-06-01

    A certified reference material (CRM) for trace elements in acidified sea water, NMIA MX014, has been produced by the National Measurement Institute Australia (NMIA). The CRM consists of natural coastal sea water with 12 elements (As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se and V) fortified to levels relevant to environmental regulatory testing in Australia ranging from 0.4 to 22 μg/kg. Certified values for these 12 elements were assigned using reference methods developed at NMIA, using either isotope dilution or standard addition with ICP-MS measurement. Specialised sample preparation (coprecipitation) and ICP-MS optimisation (online dilution, collision/reaction chemistry, high mass resolution) were used to negate the effect of the high level of dissolved solids. Multiple confirmatory experiments were performed in order to verify that ICP-MS spectral interferences were eliminated and to estimate the measurement uncertainty contribution from method precision and method trueness. Extensive homogeneity and stability testing was performed and the measurement uncertainty of certified values includes contributions from between-bottle homogeneity, short-term stability, medium-term stability and long-term stability. Special attention was paid to the stability of Hg due to well-known preservation problems. Acidified sea water matrix was satisfactory for stabilising Hg at 0.4 μg/kg for at least 4 years. Relative expanded uncertainties (k = 2) for the 12 certified values were between 1 and 11 %. NMIA MX014 is intended for use as a reference material for analytical method validation and quality control for quantification of trace elements in saline water and other similar sample types.

  15. Data collection and analysis of non-certified AirCare repairs. Online ed.

    International Nuclear Information System (INIS)

    The AirCare program was initiated to identify light duty vehicles with excessive emissions and requires vehicles to have repairs performed to the emission control system in order to pass inspections. The AirCare program only accounts for 40 per cent of the number of repair facilities in the lower mainland of British Columbia (BC). This paper presented details of a pilot project initiated to collect invoices from motorists who had repairs performed at non-certified repair facilities for a period of 16 months. Approximately 1676 invoices were collected over the period. The data from the invoices were then analyzed and compared with data from the AirCare Repair Centres. Results of the analysis showed that motorists often chose to go to non-certified repair facilities to avoid paying the charge for a diagnostic check to determine the functionality of emissions control components of a system. Repairs performed by non-certified repair facilities were as effective in reducing emissions as those performed by AirCare Repair Centres. Only half of the vehicles in the sample passed their first re-inspection. Another quarter required 1 more attempt. The remaining quarter averaged between 5 and 6 attempts before finally passing or conditionally passing. Results also indicated that many motorists perform self-diagnosis on their vehicles, which are often not effective. 7 tabs.

  16. What Do Test Scores in Texas Tell Us?

    Directory of Open Access Journals (Sweden)

    Stephen P. Klein et al

    2000-10-01

    Full Text Available We examine the results on the Texas Assessment of Academic Skills (TAAS, the highest-profile state testing program and one that has recorded extraordinary recent gains in math and reading scores. To investigate whether the dramatic math and reading gains on the TAAS represent actual academic progress, we have compared these gains to score changes in Texas on another test, the National Assessment of Educational Progress (NAEP. Texas students did improve significantly more on a fourth-grade NAEP math test than their counterparts nationally. But, the size of this gain was smaller than their gains on TAAS and was not present on the eighth-grade math test. The stark differences between the stories told by NAEP and TAAS are especially striking when it comes to the gap in average scores between whites and students of color. According to the NAEP results, that gap in Texas is not only very large but increasing slightly. According to TAAS scores, the gap is much smaller and decreasing greatly. Many schools are devoting a great deal of class time to highly specific TAAS preparation. While this preparation may improve TAAS scores, it may not help students develop necessary reading and math skills. Schools with relatively large percentages of minority and poor students may be doing this more than other schools. We raise serious questions about the validity of those gains, and caution against the danger of making decisions to sanction or reward students, teachers and schools on the basis of test scores that may be inflated or misleading. Finally, we suggest some steps that states can take to increase the likelihood that their test results merit public confidence and provide a sound basis for educational policy.

  17. The use of certified seeds of improved wheat varieties in farms and the contributions of certified seed usage to enterprise economies: the case of Ankara province in Turkey.

    Tanrivermiş, Harun; Akdoğan, Ilyas

    2007-12-15

    In this research, the use of certificated seeds of improved wheat varieties in farms of Ankara, which have an important share in wheat production of Turkey and the contributions of the certified seeds usage to enterprise economy have been evaluated by using data collected from farms via a questionnaire. The low level of use of certificated wheat seed in farms is associated with many factors, such as price of the seed (cost), yield gains and suitability of the varieties for the farming aims of producers. Average productivity is 49.5% and average net profit is 39.7% higher in the production of wheat with certificated seeds of improved varieties in farms in comparison to farming with traditional varieties. Average productivity in wheat production with uncertified seeds of improved varieties is 24.9% and net profit per unit area is 24.3% higher than wheat production with traditional varieties. The net economic benefit of wheat production using certificated seeds of improved varieties and that of wheat farming with uncertified seeds has been estimated at $ 102.40 and $ 62.70 ha(-1), respectively. Some $ 6.4 benefit is generated in return for $ 1 of expense in wheat farming with certificated seeds of improved varieties instead of traditional varieties. In the absence of state subsidies for certificated seeds the use of uncertified seeds seems to be advantageous for producers. While the amount of subsidy per hectare will be a minimum of $ 101 for certificated seeds per hectare of planting area (as technological improvement), the support will be encouraging for usage of certified seeds. Many variables, such as farm size, use of certified seeds, topography of land, production system, education level and frequency of visiting the agriculture organizations of the producers influence the level of gross profit per unit area in wheat farming. Low level of use of certificated seed in farms decreases the economic benefit of new varieties which are developed as a result of long

  20. THE EFFICIENCY OF TENNIS DOUBLES SCORING SYSTEMS

    Directory of Open Access Journals (Sweden)

    Geoff Pollard

    2010-09-01

    Full Text Available In this paper a family of scoring systems for tennis doubles for testing the hypothesis that pair A is better than pair B versus the alternative hypothesis that pair B is better than A, is established. This family or benchmark of scoring systems can be used as a benchmark against which the efficiency of any doubles scoring system can be assessed. Thus, the formula for the efficiency of any doubles scoring system is derived. As in tennis singles, one scoring system based on the play-the-loser structure is shown to be more efficient than the benchmark systems. An expression for the relative efficiency of two doubles scoring systems is derived. Thus, the relative efficiency of the various scoring systems presently used in doubles can be assessed. The methods of this paper can be extended to a match between two teams of 2, 4, 8, …doubles pairs, so that it is possible to establish a measure for the relative efficiency of the various systems used for tennis contests between teams of players.

    have been claimed to have a smaller effect on hedonic scores than other attribute such as just-about-right or intensity scales. In this research, nine studies using consumers as participants examined effects on hedonic product scores when sensory attribute information was co-elicited using CATA...... questions. The use of CATA concurrently with hedonic was benchmarked against concurrent attribute liking scores, attribute intensity scores and just-about-right scaling. Across a range of product categories (beer, fresh fruit, tea, flavoured water, crackers, savoury dips), only weak and transient evidence...... (appearance, aroma, flavour, taste, aftertaste, mouthfeel). The present research suggests that co-elicitation of hedonic scores and product attribute information using CATA questions may bias the hedonic scores, but not that it certainly will do so.

    Full Text Available "nCoronary artery disease is the single largest cause of mortality, and is implicated in one of every five deaths. Conventional risk factors fail to identify one third of deaths caused by CAD. The currently available screening tools for coronary artery disease include Framingham risk assessment, clinical examination, and stress testing. "nIt is of interest that most coronary events occur in the territory of coronary arteries that do not demonstrate prior high grade stenosis. "nComplications of atherosclerotic plaque such as rupture or erosion with subsequent thrombus formation are important events leading to acute coronary syndrome. "nMany different factors including plaque composition, hemodynamic, endothelial function, and blood thrombogenicity may influence which plaques lead to hemodynamically significant events. "nNonetheless, there is a strong relation between the extent of coronary plaque burden and the risk of coronary event. "nSince atherosclerosis is the only disease process associated with calcification of coronary arteries, the degree of coronary calcification as demonstrated by CT is predictive of the overall burden of atherosclerotic plaque. "nThe role of coronary calcium scoring in assessing the risk for future coronary events has been a subject of considerable controversy. It is most important to understand that an elevated burden of coronary calcium may not indicate the presence of significant coronary stenosis, but is associated with a higher risk of a coronary event. "nCalcium scoring is based on the identification of high density material within the coronary circulation on a noncontrast CTscan. Both the EBCT and MDCT have been used for the evaluation of coronary calcium. "nThe current literature suggests that MDCT is comparable to EBCT for coronary calcium screening. "nCalcium scoring is a simple test that should take no more than 5 minutes. A prospective ECG gated scan with 3 mm slice thickness is obtained from the level of

    Under the existing system, it is difficult for the people's court to undertake the task of substantive examination of state secrets, and it is also enable to form an effective control over the excessive secrecy behaviors by administrative organs. Therefore,a more diversified solution method concerning the secret determination objection should be established. On one hand, backing to the Expert Proposal of the Government Information Publicity Regulation, the information committee should be set up. On the other hand, the citizens should be given the right of secret determination objection. Combined with experience of Japan, the United States and other countries and regions, this paper conducts discussions on related legal issues such as the position of the information committee, the relationship between the committee and the administrative reconsideration committee, and the system compare between secret determination objection and compulsorydecryption review, etc.%在现有体制下,人民法院难以承担对国家秘密进行实质审查的任务,亦无力对行政机关的过度保密行为形成有效的制约。应当建立更加多元化的定密争议解决方式,以推动政府信息公开:一是重拾《政府信息公开条例专家建议稿》中的方案,建立信息委员会;二是赋予公民定密异议权。结合日本、美国等国家和地区的经验,就信息委员会的定位、信息委员会与行政复议委员会的关系、定密异议与强制解密审查制度的比较等相关法律问题进行探讨,具有现实意义。

    The Roundtable on Sustainable Palm Oil (RSPO) is responsible for the certification of palm oil producers that comply with sustainability standards. However, it is not known whether RSPO-certified plantations are effective in maintaining biodiversity. Focusing on Peninsular Malaysia, we show that both RSPO-certified plantations and uncertified large-scale plantations are characterized by very low levels of landscape heterogeneity. By contrast, heterogeneity measures were many times higher in p...

    2015-07-01

    Full Text Available An effective workforce performing within the context of a positive cultural environment is central to a healthcare organization’s ability to achieve quality outcomes. The Nursing Culture Assessment Tool (NCAT provides nurses with a valid and reliable tool that captures the general aspects of nursing culture. This study extends earlier work confirming the tool’s construct validity and dimensionality by standardizing the scoring approach and establishing norm-referenced scoring. Scoring standardization provides a reliable point of comparison for NCAT users. NCAT assessments support nursing’s ability to evaluate nursing culture, use results to shape the culture into one that supports change, and advance nursing’s best practices and care outcomes. Registered nurses, licensed practical nurses, and certified nursing assistants from 54 long-term care facilities in Kentucky, Nevada, North Carolina, and Oregon were surveyed. Confirmatory factor analysis yielded six first order factors forming the NCAT’s subscales (Expectations, Behaviors, Teamwork, Communication, Satisfaction, Commitment (Comparative Fit Index 0.93 and a second order factor—The Total Culture Score. Aggregated facility level comparisons of observed group variance with expected random variance using rwg(J statistics is presented. Normative scores and cumulative rank percentages and how the NCAT can be used in implementing planned change are provided.

    Poor pain management practices are generally discussed in terms of barriers associated with the patient, clinician and/or health care organization. The impact of deficiencies in the tools that are used to measure pain are seldom addressed. Three factors are discussed that complicate the measurement of pain: the nature of pain, the lack of meaning associated with scores generated by pain scales, and treatment goals that lack specificity and are not linked to patients' pain scores. The m...

    Although some scholars maintain that education has little effect on intelligence quotient (IQ) scores, others claim that IQ scores are indeed malleable, primarily through intervention in early childhood. The causal effect of education on IQ at later ages is often difficult to uncover because analyses based on observational data are plagued by problems of reverse causation and self-selection into further education. We exploit a reform that increased compulsory schooling from 7 to 9 y in Norway...

  18. Genetic evaluation of elbow scores and the relationship with hip scores in UK Labrador retrievers.

    Lewis, T W; Ilska, J J; Blott, S C; Woolliams, J A

    2011-08-01

    A linear mixed model analysis of elbow and hip score data from UK Labrador retrievers was used to estimate the heritability of elbow score (0.16-0.19) and to determine a moderate and beneficial genetic correlation with hip score (0.40). A small improvement in the genetic trend of elbow score was observed during the years 2000-2008, equivalent to avoiding only the worst 3-4% of scored dogs for breeding, but close to what may have been anticipated if the current British Veterinary Association-approved guidelines were followed. Calculations suggested that a correlated response to indirect selection on hip score may elicit a greater response than direct selection on elbow score and that the genetic trend in elbow score may be explained as a consequence of the stronger selection pressure that has been placed on hip score. Increases in the accuracy of estimated breeding values for elbow score of 4-7% for dogs with elbow data only and 7-11% for dogs with both hip and elbow score were observed from bivariate analysis of elbow and hip data. A selection index confirmed the benefits of bivariate analysis of elbow and hip score data by identifying increases in accuracy (directly related to the response to selection) of 14% from the use of optimum coefficients compared to use of hip data only. The quantified genetic correlation means that hip score effectively acts as a 'secondary indicator' of elbow score in this breed and the preponderance of hip data means that it acts as a major source of information that may be used to improve the accuracy of estimates of genetic risk for elbow dysplasia.

  19. Costs of certified emission reductions under the Clean Development Mechanism of the Kyoto Protocol

    International Nuclear Information System (INIS)

    This paper examines the cost structure of certified emission reductions (CERs) through various types of projects under the Clean Development Mechanism (CDM) of the Kyoto Protocol. Using the CDM project data, the costs of CERs and their variation across technology and over time and space are estimated by applying alternative functional forms and specifications. Results show that the average cost of CERs decreases with the project scale and duration, scale and duration effects significantly vary across project types, and there is an upward trend in costs. The results also show that the distribution of the projects in the CDM portfolio or a given location does not strictly follow the relative cost structure, nor does the distribution of the CDM projects in different host countries follow the principle of comparative advantage. More than 84% of the CDM portfolio consists of various energy projects with substantially higher costs of CERs than afforestation and reforestation, industrial and landfill gas reduction, and methane avoidance projects, which are only 12% of all projects. While per unit cost of abatement plays an important role in the bottom-up and top-down models to evaluate emission reduction potential and analyze policy alternatives, the findings contradict the presumption of such models that project investors seek out low-cost opportunities. At the aggregate level, the cost of CER by the projects in Asia and Europe is similar but higher than those hosted in Africa, Americas, and Oceania. Yet more than 83% of the projects in the CDM portfolio are located in Asia; more than 69% of the projects are in China and India alone. China appears to have a comparative advantage (i.e., lowest opportunity cost) in energy efficiency projects, while India has a comparative advantage in hydro power projects and Brazil has a comparative advantage in wind power projects. In contrast, energy efficiency category accounts for only 8% of the CDM projects in China, hydro power

  1. Development of a candidate certified reference material of cypermethrin in green tea

    International Nuclear Information System (INIS)

    Highlights: ► A cypermethrin CRM in green tea was developed. ► Using two isotope dilution mass spectrometry techniques for characterization. ► Certified value of 148 μg kg−1 with expanded uncertainty of ±9.2%. ► Support quality assurance of pesticide residue analysis in tea to testing. - Abstract: This paper presents the preparation of a candidate certified reference material (CRM) of cypermethrin in green tea, GLHK-11-01a according to the requirements of ISO Guide 34 and 35. Certification of the material was performed using a newly developed isotope dilution mass spectrometry (IDMS) approach, with gas chromatography high resolution mass spectrometry (GC–HRMS) and gas chromatography–tandem mass spectrometry (GC–MS/MS). Statistical analysis (one-way ANOVA) showed excellent agreement of the analytical data sets generated from the two mass spectrometric detections. The characterization methods have also been satisfactorily applied in an Asia-Pacific Metrology Program (APMP) interlaboratory comparison study. Both the GC–HRIDMS and GC–IDMS/MS methods proved to be sufficiently reliable and accurate for certification purpose. The certified value of cypermethrin in dry mass fraction was 148 μg kg−1 and the associated expanded uncertainty was 14 μg kg−1. The uncertainty budget was evaluated from sample in homogeneity, long-term and short-term stability and variability in the characterization procedure. GLHK-11-01a is primarily developed to support the local and wider testing community on need basis in quality assurance work and in seeking accreditation.

    Full Text Available To investigate the performance of hematoma shape, hematoma size, Glasgow coma scale (GCS score, and intracerebral hematoma (ICH score in predicting the 30-day mortality for ICH patients. To examine the influence of the estimation error of hematoma size on the prediction of 30-day mortality.This retrospective study, approved by a local institutional review board with written informed consent waived, recruited 106 patients diagnosed as ICH by non-enhanced computed tomography study. The hemorrhagic shape, hematoma size measured by computer-assisted volumetric analysis (CAVA and estimated by ABC/2 formula, ICH score and GCS score was examined. The predicting performance of 30-day mortality of the aforementioned variables was evaluated. Statistical analysis was performed using Kolmogorov-Smirnov tests, paired t test, nonparametric test, linear regression analysis, and binary logistic regression. The receiver operating characteristics curves were plotted and areas under curve (AUC were calculated for 30-day mortality. A P value less than 0.05 was considered as statistically significant.The overall 30-day mortality rate was 15.1% of ICH patients. The hematoma shape, hematoma size, ICH score, and GCS score all significantly predict the 30-day mortality for ICH patients, with an AUC of 0.692 (P = 0.0018, 0.715 (P = 0.0008 (by ABC/2 to 0.738 (P = 0.0002 (by CAVA, 0.877 (P<0.0001 (by ABC/2 to 0.882 (P<0.0001 (by CAVA, and 0.912 (P<0.0001, respectively.Our study shows that hematoma shape, hematoma size, ICH scores and GCS score all significantly predict the 30-day mortality in an increasing order of AUC. The effect of overestimation of hematoma size by ABC/2 formula in predicting the 30-day mortality could be remedied by using ICH score.

  11. Objective structured clinical examination in radiology

    2010-01-01

    Full Text Available There is a growing need for introducing objective structured clinical examination (OSCE as a part of radiology practical examinations in India. OSCE is an established, reliable, and effective multistation test for the assessment of practical professional skills in an objective and a transparent manner. In India, it has been successfully initiated and implemented in specialties like pediatrics, ophthalmology, and otolaryngology. Each OSCE station needs to have a pre-agreed "key-list" that contains a list of objective steps prepared for uniformly assessing the tasks given to students. Broadly, OSCE stations are classified as "manned" or "unmanned" stations. These stations may include procedure or pictorial or theory stations with clinical oriented contents. This article is one of a series of measures to initiate OSCE in radiology; it analyzes the attributes of OSCE stations and outlines the steps for implementing OSCE. Furthermore, important issues like the advantages of OSCE, its limitations, a strengths, weaknesses, opportunities, and threats (SWOT analysis, and the timing of introduction of OSCE in radiology are also covered. The OSCE format in radiology and its stations needs to be validated, certified, and finalized before its use in examinations. This will need active participation and contribution from the academic radiology fraternity and inputs from faculty members of leading teaching institutions. Many workshops/meetings need to be conducted. Indeed, these collaborative measures will effectively sensitize universities, examiners, organizers, faculty, and students across India to OSCE and help successfully usher in this new format in radiology practical examinations.

    2016-01-01

    The Angoff method is a commonly used and legally defensible method for setting passing or cut scores for high-stakes examinations. It also can be used for setting passing scores on clinical skill checklists. Two variations of the Angoff method were compared with a traditional and arbitrary 75% passing score, using a Foley catheter insertion checklist as an exemplar. Both Angoff methods produced slightly lower scores than our traditional scoring; because of "must pass" steps on our checklist, 12 of 13 students still failed the evaluation. The project uncovered multiple variations of checklists within different courses and variations in teaching practices for this skill. PMID:26402909

  13. Validating a Prognostic Scoring System for Postmastectomy Locoregional Recurrence in Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: This study is designed to validate a previously developed locoregional recurrence risk (LRR) scoring system and further define which groups of patients with breast cancer would benefit from postmastectomy radiation therapy (PMRT). Methods and Materials: An LRR risk scoring system was developed previously at our institution using breast cancer patients initially treated with modified radical mastectomy between 1990 and 2001. The LRR score comprised 4 factors: patient age, lymphovascular invasion, estrogen receptor negativity, and number of involved lymph nodes. We sought to validate the original study by examining a new dataset of 1545 patients treated between 2002 and 2007. Results: The 1545 patients were scored according to the previously developed criteria: 920 (59.6%) were low risk (score 0-1), 493 (31.9%) intermediate risk (score 2-3), and 132 (8.5%) were high risk (score ≥4). The 5-year locoregional control rates with and without PMRT in low-risk, intermediate-risk, and high-risk groups were 98% versus 97% (P=.41), 97% versus 91% (P=.0005), and 89% versus 50% (P=.0002) respectively. Conclusions: This analysis of an additional 1545 patients treated between 2002 and 2007 validates our previously reported LRR scoring system and suggests appropriate patients for whom PMRT will be beneficial. Independent validation of this scoring system by other institutions is recommended

  15. Morphologic and functional scoring of cystic fibrosis lung disease using MRI

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MRI) gains increasing importance in the assessment of cystic fibrosis (CF) lung disease. The aim of this study was to develop a morpho-functional MR-scoring-system and to evaluate its intra- and inter-observer reproducibility and clinical practicability to monitor CF lung disease over a broad severity range from infancy to adulthood. 35 CF patients with broad age range (mean 15.3 years; range 0.5–42) were examined by morphological and functional MRI. Lobe based analysis was performed for parameters bronchiectasis/bronchial-wall-thickening, mucus plugging, abscesses/sacculations, consolidations, special findings and perfusion defects. The maximum global score was 72. Two experienced radiologists scored the images at two time points (interval 10 weeks). Upper and lower limits of agreement, concordance correlation coefficients (CCC), total deviation index and coverage probability were calculated for global, morphology, function, component and lobar scores. Global scores ranged from 6 to 47. Intra- and inter-reader agreement for global scores were good (CCC: 0.98 (R1), 0.94 (R2), 0.97 (R1/R2)) and were comparable between high and low scores. Our results indicate that the proposed morpho-functional MR-scoring-system is reproducible and applicable for semi-quantitative evaluation of a large spectrum of CF lung disease severity. This scoring-system can be applied for the routine assessment of CF lung disease and maybe as endpoint for clinical trials.

    2013-03-01

    In the monitoring of progression of lung disease in patients with cystic fibrosis (CF), recurrent computed tomography (CT) examinations are often used. The relatively new imaging technique chest tomosynthesis (CTS) may be an interesting alternative in the follow-up of these patients due to its visualization of the chest in slices at radiation doses and costs significantly lower than is the case with CT. A first step towards introducing CTS imaging in the diagnostics of CF patients is to establish a scoring system appropriate for evaluating the severity of CF pulmonary disease based on findings in CTS images. Previously, several such CF scoring systems based on CT imaging have been published. The purpose of the present study was to develop a CF scoring system for CTS, by starting from an existing scoring system dedicated for CT images and making modifications regarded necessary to make it appropriate for use with CTS images. In order to determine any necessary changes, three thoracic radiologists independently used a scoring system dedicated for CT on both CT and CTS images from CF patients. The results of the scoring were jointly evaluated by all the observers, which lead to suggestions for changes to the scoring system. Suggested modifications include excluding the scoring of air trapping and doing the scoring of the findings in quadrants of the image instead of in each lung lobe.

    Full Text Available Aims: To investigate initial Sequential Organ Failure Assessment (SOFA score of patients in Intensive Care Unit (ICU, who were diagnosed with infectious disease, as an indicator of multiple organ dysfunction and to examine if initial SOFA score is a better mortality predictor compared to Simplified Acute Physiology Score (SAPS. Materials and Methods: Hospital-based study done in medical ICU, from June to September 2014 with a sample size of 48. Patients aged 18 years and above, diagnosed with infectious disease were included. Patients with history of chronic illness (renal/hepatic/pulmonary/  cardiovascular, diabetes, hypertension, chronic obstructive pulmonary disease, heart disease, those on immunosuppressive therapy/chemoradiotherapy for malignancy and patients in immunocompromised state were excluded. Blood investigations were obtained. Six organ dysfunctions were assessed using initial SOFA score and graded from 0 to 4. SAPS was calculated as the sum of points assigned to each of the 17 variables (12 physiological, age, type of admission, and three underlying diseases. The outcome measure was survival status at ICU discharge. Results: We categorized infectious diseases into dengue fever, leptospirosis, malaria, respiratory tract infections, and others which included undiagnosed febrile illness, meningitis, urinary tract infection and gastroenteritis. Initial SOFA score was both sensitive and specific; SAPS lacked sensitivity. We found no significant association between age and survival status. Both SAPS and initial SOFA score were found to be statistically significant as mortality predictors. There is significant association of initial SOFA score in analyzing organ dysfunction in infectious diseases (P < 0.001. SAPS showed no statistical significance. There was statistically significant (P = 0.015 percentage of nonsurvivors with moderate and severe dysfunction, based on SOFA score. Nonsurvivors had higher SAPS but was not statistically

    Full Text Available Objective : The aim of this study is to assess the intra- and interobserver concordance of SINS, Harrington, Tokuhashi and Tomita scores among general orthopedic surgeons and spine surgeons with experience above 5 and 10 years in the evaluation of patients with spinal metastasis. Methods : Twenty cases of patients with metastatic lesion of the spine were presented to 10 examiners and the scores aforementioned have been applied. After six weeks, the cases were reintroduced in a different order and data were analyzed. Results : The intraobserver reliability showed better agreement in SINS score among examiners with less experience and Harrington and Tomita scores among those who had more than 10-year experience. The interobserver reliability of the examiners of the group with over 10-year experience showed higher precision when using these scores, especially Harrington and Tomita. The SINS score was the choice for daily practice and was able to modify the management more often. Conclusions : This study demonstrated that the use of predictive scores of instability, Harrington, and prognosis, Tomita, had a higher intra- and interobserver reliability particularly among spine surgeons with experience above 10 years.

    Full Text Available Scoring systems have been developed to interpret the disease severity objectively by evaluating the parameters of the disease. Body surface area, visual analogue scale, and physician global assessment are the most frequently used scoring systems for evaluating the clinical severity of the dermatological diseases. Apart from these scoring systems, many specific scoring systems for many dermatological diseases, including acne (acne vulgaris, acne scars, alopecia (androgenetic alopecia, tractional alopecia, bullous diseases (autoimmune bullous diseases, toxic epidermal necrolysis, dermatitis (atopic dermatitis, contact dermatitis, dyshidrotic eczema, hidradenitis suppurativa, hirsutismus, connective tissue diseases (dermatomyositis, skin involvement of systemic lupus erythematosus (LE, discoid LE, scleroderma, lichen planoplaris, mastocytosis, melanocytic lesions, melasma, onychomycosis, oral lichen planus, pityriasis rosea, psoriasis (psoriasis vulgaris, psoriatic arthritis, nail psoriasis, sarcoidosis, urticaria, and vitiligo, have also been developed. Disease severity scoring methods are ever more extensively used in the field of dermatology for clinical practice to form an opinion about the prognosis by determining the disease severity; to decide on the most suitable treatment modality for the patient; to evaluate the efficacy of the applied medication; and to compare the efficiency of different treatment methods in clinical studies.
