    The central role of the propensity score analysis (PSA) in observational studies is for causal inference; as such, PSA is often used for making causal claims in research articles. However, there are still some issues for researchers to consider when making claims of causality using PSA results. This summary first briefly reviews PSA, followed by…

  3. Original article Stability of WISC-R scores in students with borderline intellectual functioning

    Full Text Available BACKGROUND Previous studies on the measurement of intelligence in students with learning difficulties indicate low stability of results observed over time. Therefore, careful analysis of changes in intelligence quotient, as well as in results within Verbal and Performance scale subtests, is necessary. PARTICIPANTS AND PROCEDURE The aim of the research was to analyze changes in WISC-R scores over time in students with borderline intellectual functioning. Test-retest stability of WISC-R was evaluated for Full, Verbal (VIQ, and Performance (PIQ scales. The study involved 30 students, who were tested three times, when their mean age was 8, 10.8, and 13.6 years old. RESULTS The results showed that Full Scale IQ was fairly stable over time and remained below the average level, between –1.01 and –2.00 standard deviations. Significant changes were observed in the Verbal and Performance scale; VIQ decreased and PIQ increased over time. An initially insignificant statistical difference between the scales grew as time progressed. Furthermore, considerable subtest score fluctuation was observed; over time scores in the Vocabulary subtest significantly decreased whereas in Block Design and Picture Arrangement they increased. CONCLUSIONS The authors argue that delayed acquisition of verbal skills may result from chronic school failure and deficiency of educational support experienced by this group of students. Meanwhile, non-verbal skills, that are less dependent on educational influences and academic knowledge, improve with students’ development through their engagement in everyday life activities.

    Hip dysplasia (HD) scores, based on the five grades, as defined by the Fédération Cynologique Internationale, were compared between anaesthetized (group 1, n = 3839) and non-sedated non-anaesthetized dogs (group 2, n = 1517). Each dog was radiographed in the standard ventro-dorsal hip joint extended position. Each radiograph was evaluated by the same reader blinded regarding the dog's status of anaesthesia. Results showed that there was a significant difference in hip dysplasia prevalence between group 1 (22%) compared with group 2 (9%) (P < 0.005). This difference was the result of a lower rate of hip-joint laxity assessment and the measurement of Norberg-Olsson angle <105 degrees in group 2 compared with group 1. The acetabular and femoral morphologies were not significantly different between the groups. The data confirm that the scoring of dogs for HD on standard radiographs with the hip joints extended is influenced by anaesthesia. PMID:16970631

    2015-11-01

    Markov processes are widely used to model the dynamics of a credit portfolio and forecast the portfolio risk and profitability. In the Markov chain model the loan portfolio is divided into several groups with different quality, which determined by presence of indebtedness and its terms. It is proposed that dynamics of portfolio shares is described by a multistage controlled system. The article outlines mathematical formalization of controls which reflect the actions of the bank's management in order to improve the loan portfolio quality. The most important control is the organization of approval procedure of loan applications. The credit scoring is studied as a control affecting to the dynamic system. Different formalizations of "good" and "bad" consumers are proposed in connection with the Markov chain model.

    2010-07-01

    In this study, we investigated if freshman student's participation in small group discussions in the tutorial sessions would influence their score of the Lao version of the Force Concept Inventory test (LFCI). We used the LFCI version to test 188 students" understanding of mechanics concepts before and after they studied mechanics at university. In three classes the students used group discussions when they solved the end-of-chapter questions in the textbook during tutorials and they also used group discussions to answer the LFCI. We video recorded three groups when they solved end-of-chapter questions. In two classes the students both solved the problems and answered the LFCI individually. A questionnaire about advantages and disadvantages of cooperative group and individual problem solving were handed out to the students. The questionnaire was supplemented by interviews with four students and three groups. We found that almost all students would like to work with group discussions; only 3% of them were negative. Students that worked with group discussions obtained an average score of 26% correct answers to the LFCI which was slightly higher than the average score of 23% for students that worked individually. The improvement from the pre- to the post-test in average score was 7 percentage points for classes with group discussions and 6 percentage points for classes with individual problem solving. It is not possible to claim that one of these ways of study will result in a larger improvement in the LFCI-score. Apparently, the group discussions did not help the students to improve their theoretical understanding of mechanics concepts as it is tested by the LFCI. However, it was observed in the video analysis that group discussions helped students to better understand mechanics concepts in the context of solving the end-of-chapter questions in the textbook. This observation was also supported by the students' answers to the questionnaire and the interview.

    Catchment and riparian degradation has resulted in declining ecosystem health of streams worldwide. With restoration a priority in many regions, there is an increasing interest in the scale at which land use influences stream ecosystem health. Our goal was to use a substantial data set collected as part of a monitoring program (the Southeast Queensland, Australia, Ecological Health Monitoring Program data set, collected at 116 sites over six years) to identify the spatial scale of land use, or the combination of spatial scales, that most strongly influences overall ecosystem health. In addition, we aimed to determine whether the most influential scale differed for different aspects of ecosystem health. We used linear-mixed models and a Bayesian model-averaging approach to generate models for the overall aggregated ecosystem health score and for each of the five component indicators (fish, macroinvertebrates, water quality, nutrients, and ecosystem processes) that make up the score. Dense forest close to the survey site, mid-dense forest in the hydrologically active near-stream areas of the catchment, urbanization in the riparian buffer, and tree cover at the reach scale were all significant in explaining ecosystem health, suggesting an overriding influence of forest cover, particularly close to the stream. Season and antecedent rainfall were also important explanatory variables, with some land-use variables showing significant seasonal interactions. There were also differential influences of land use for each of the component indicators. Our approach is useful given that restoring general ecosystem health is the focus of many stream restoration projects; it allowed us to predict the scale and catchment position of restoration that would result in the greatest improvement of ecosystem health in the regions streams and rivers. The models we generated suggested that good ecosystem health can be maintained in catchments where 80% of hydrologically active areas in close

  18. The influence of motion artifacts conditioned by reconstruction, on the coronary calcium score in multislice spiral CT

    International Nuclear Information System (INIS)

    Purpose: A major problem of the quantification of coronary calcifications is a high variability of the coronary calcium score between recurrent examinations and different observers. Aim of our study is to evaluate the influence of different RR-intervals on the coronary calcium score utilizing retrospectively gated multislice spiral CT (MSCT) data sets. Materials and Method: 50 consecutive patients underwent MSCT examination (Somatom Volume Zoom, Siemens, Forchheim, G) utilizing a standardized scan protocol (4 x 2.5 mm collimation, 3 mm increment, tube current 133 mAs, tube voltage 120 kV). Retrospectively gated image reconstruction was performed every 10% of the RR interval. Coronary calcification was evaluated by the Agatston score. Coronary risk assessment was performed in all patients with image reconstruction beginning at 80% of the RR interval. The reconstruction intervals with the least motion artifacts were identified and chosen as reference for a reevaluation of the coronary risk. The results of different reconstruction times were compared. Results: The mean calcium score was 551.6. The calcium score varied between 512.2 (90%) and 571.7 (70%), depending on the image reconstruction interval. Compared to the mean calcium score a new classification of the coronary risk was necessary in 7/50 of the patients at 80% reconstruction interval, and in 2/50 of the patients at 50% of the RR interval, respectively. Conclusion: Movement of the coronary arteries at different image reconstruction intervals has an important influence on the coronary calcium score. Based on our data, we propose image reconstruction at 50% of the RR interval for evaluation of the coronary calcium score by MSCT. (orig.)

    In 1944, John Willis produced a summary of his meticulous record keeping of weather and plants over the 30 years 1913 1942. This publication contains fixed-date, fixed-subject photography taken on the 1st of each month from January to May, using as subjects snowdrop Galanthus nivalis, daffodil Narcissus pseudo-narcissus, horse chestnut Aesculus hippocastanum and beech Fagus sylvatica. We asked 38 colleagues to assess rapidly the plant development in each of these photographs according to a supplied five-point score. The mean scores from this exercise were assessed in relation to mean monthly weather variables preceding the date of the photograph and the consistency of scoring was examined according to the experience of the recorders. Plant development was more strongly correlated with mean temperature than with minimum or maximum temperatures or sunshine. No significant correlations with rainfall were detected. Whilst mean scores were very similar, botanists were more consistent in their scoring of developmental stages than non-botanists. However, there was no overall pattern for senior staff to be more consistent in scoring than junior staff. These results suggest that scoring of plant development stages on fixed dates could be a viable method of assessing the progress of the season. We discuss whether such recording could be more efficient than traditional phenology, especially in those sites that are not visited regularly and hence are less amenable to frequent or continuous observation to assess when a plant reaches a particular growth stage.

    Fearon, Angela; Dahlstrom, Jane E.; Twin, Jane; Cook, Jill; Scott, Alex

    2016-01-01

    Objectives Tendinopathy is a common, costly condition affecting both sporting and sedentary populations. Research into tendinopathy frequently involves the evaluation of tendinosis, a pathology characterized by a lack of inflammatory cells, collagen disruption, neovascularisation, altered cell numbers and morphology and increased glycosaminoglycans. Evaluation of these characteristics can be undertaken using the Bonar histopathology score, but the characteristics are heterogeneous throughout tendon specimens with no standardized method of determining the area to be evaluated. The objective of this study was to assess whether the Bonar score varies depending on the criteria used to define the area of evaluation. Design Case series. Methods Two independent assessors, with a third to resolve disputes, evaluated 103 areas from 35 tendon specimens using the Bonar score. Specimens were scored once each in the area of worst collagen disruption, degree of vascularization, and cell morphological changes. The inter-tester reliability of the updated Bonar scale was good (r2 = 0.71) Results The Bonar score was highest in the areas of worst cell morphological (CM) changes, followed by collagen disruption (CD) and lowest for the area of most extensive vascular proliferation (VS) (regression: CD vs. CM, p = 0.008, CM vs. VS, p < 0.001, CD vs. VS, p = 0.013). Suggested modifications to the Bonar score include the addition of a cellularity domain, specific definitions of hypo- and hypercellularity, and changes to the vascularity score to include pathological avascularity. Conclusions The updated Bonar score includes a standardized method of selecting the area of evaluation, which should provide increased reliability when assessing the extent of tendon degeneration.

    2001-12-01

    Full Text Available Before a principled explanation of variability in raters' judgements of ESL compositions can be offered, the process of constructing scoring criteria and the manner in which prior experience enters this process must be analyzed. Therefore, utilizing protocol and intewiew data collected in the context of a comparative study, a case study will describe how one experienced rater dealt with the following operations while assessing a corpus of 60 TOEFL essays: establishing the purpose of assessment, developing a reading strategy to deal with a corpus of essays, and collecting context-specific information. Within each operation, the influence of background variables such as teaching and assessment experience will be examined, particularly on determining what type of information to collect, and on articulating expectations concerning test takers, test scores and the textual qualities of essays. The results of the study will be used to specific directions for future research into explaining inter-rater variability.

    2016-09-01

    Despite their recognized limitations, bibliometric assessments of scientific productivity have been widely adopted. We describe here an improved method to quantify the influence of a research article by making novel use of its co-citation network to field-normalize the number of citations it has received. Article citation rates are divided by an expected citation rate that is derived from performance of articles in the same field and benchmarked to a peer comparison group. The resulting Relative Citation Ratio is article level and field independent and provides an alternative to the invalid practice of using journal impact factors to identify influential papers. To illustrate one application of our method, we analyzed 88,835 articles published between 2003 and 2010 and found that the National Institutes of Health awardees who authored those papers occupy relatively stable positions of influence across all disciplines. We demonstrate that the values generated by this method strongly correlate with the opinions of subject matter experts in biomedical research and suggest that the same approach should be generally applicable to articles published in all areas of science. A beta version of iCite, our web tool for calculating Relative Citation Ratios of articles listed in PubMed, is available at https://icite.od.nih.gov. PMID:27599104

    2016-06-01

    To make good decisions, operating room (OR) managers often act autocratically after obtaining expert advice. When such advice is provided by e-mail, attachments of research articles can be included. We performed a quasi-experimental study using an evaluation of 4 articles used in a 50-hour OR management course to assess how their content influences trust in the article's content, including its quality, usefulness, and reliability. There were (a) 2 articles containing data with specific examples of application for health systems and 2 without and (b) 2 articles containing appendices of formulas and 2 without. Some of the formulas in the readings were relatively complicated (e.g., stochastic optimization using the Lagrange method) and unlikely to be used by the subjects (i.e., they show what does not need to be done). Content complexity (±data, ±formulas) served both as sources of limitation in understanding the content and potentially as peripheral cues influencing perception of the content. The 2-page evaluation forms were generated with random sequences of articles and response items. The N = 17 subjects each completed 9 items about each of the 4 articles (i.e., answered 36 questions). The 9-item assessment of trust provided a unidimensional construct (Cronbach α, 0.94). Formulas in the articles significantly increased trust in the information (P = 0.0019). Presence of data did not significantly influence trust (P = 0.15). Therefore, when an expert sends e-mail to a manager who has completed this basic OR management science and asks a question, choosing a paper with formulas has no disadvantage. PMID:27166745

    2016-01-01

    Eight standard inbred mouse strains were evaluated for ethanol effects on a refined battery of behavioral tests in a study that was originally designed to assess the influence of rat odors in the colony on mouse behaviors. As part of the design of the study, two experimenters conducted the tests, and the study was carefully balanced so that equal numbers of mice in all groups and times of day were tested by each experimenter. A defect in airflow in the facility compromised the odor manipulation, and in fact the different odor exposure groups did not differ in their behaviors. The two experimenters, however, obtained markedly different results for three of the tests. Certain of the experimenter effects arose from the way they judged behaviors that were not automated and had to be rated by the experimenter, such as slips on the balance beam. Others were not evident prior to ethanol injection but had a major influence after the injection. For several measures, the experimenter effects were notably different for different inbred strains. Methods to evaluate and reduce the impact of experimenter effects in future research are discussed. PMID:24933191

  15. Citation analysis as a measure of article quality, journal influence and individual researcher performance

    International Nuclear Information System (INIS)

    The research-related performance of universities, as well as that of individual researchers, is increasingly evaluated through the use of objective measures, or metrics, which seek to support or in some cases even replace more traditional methods of peer review. In particular there is a growing awareness in research communities, government organisations and funding bodies around the concept of using evaluation metrics to analyse research citations. The tools available for ‘citation analysis’ are many and varied, enabling a quantification of scientific quality, academic impact and prestige. However there is increasing concern regarding the potential misuse of such tools, which have limitations in certain research disciplines. This article uses ‘real world’ examples from radiography research and scholarship to illustrate the range of currently available citation analysis tools. It explores the academic debate surrounding their strengths and limitations, and identifies the potential impact of citation analysis on the radiography research community. The article concludes that citation analysis is a valuable tool for researchers to use for personal reflection and research planning, yet there are inherent dangers if it is used inappropriately. Whilst citation analysis can give objective information regarding an individual, research group, journal or higher education institution, it should not be used as a total substitute for traditional qualitative review and peer assessment.

    The Affordable Care Act of 2010 launch of Medicare Value-Based Purchasing has become the platform for payment reform. It is a mechanism by which buyers of health care services hold providers accountable for high-quality and cost-effective care. The objective of the study was to examine the relationship between quality of hospital care and hospital competition using the quality-quantity behavioral model of hospital behavior. The quality-quantity behavioral model of hospital behavior was used as the conceptual framework for this study. Data from the American Hospital Association database, the Hospital Compare database, and the Area Health Resources Files database were used. Multivariate regression analysis was used to examine the effect of hospital competition on patient mortality. Hospital market competition was significantly and negatively related to the 3 mortality rates. Consistent with the literature, hospitals located in more competitive markets had lower mortality rates for patients with acute myocardial infarction, heart failure, and pneumonia. The results suggest that hospitals may be more readily to compete on quality of care and patient outcomes. The findings are important because policies that seek to control and negatively influence a competitive hospital environment, such as Certificate of Need legislation, may negatively affect patient mortality rates. Therefore, policymakers should encourage the development of policies that facilitate a more competitive and transparent health care marketplace to potentially and significantly improve patient mortality.

    Full Text Available Neuropathological studies are crucial for the new knowledge on pathophysiology and treatment of neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease. The postmortem brain tissue processing method directly impacts on both the appropriate integrity and the biomolecules detection by different histological and molecular biology techniques. In this review we will discuss topics on the influence of some external factors on the preservation of the brain tissue for histological studies (histochemistry and immunohistochemistry, such as factors either prior or after the death, and the chosen method for the preservation of nervous tissue. By means of a specific example, we propose a strict record of various conditions involved in the method of preservation of nervous tissue, and its correlation with variables that measure the quality of the histological sample as markers of preservation of biological material for further studies.

    Full Text Available Background and Context: Beta - blockers have been used for attenuation of stress response, decreasing anaesthetic requirement and augmentation of the effect of opioids during general anaesthesia. Aims and Objectives: The present study aims to evaluate the influence of esmolol on the requirement of an inhalational agent while monitoring the depth of anaesthesia by entropy and also its effect on immediate postoperative pain score. Methods: Fifty American Society of Anaesthesiologists (ASA I and II patients, between 25 and 65 years of age who underwent lower abdominal surgeries were randomly allocated to two groups: Group E and Group S of 25 patients each. Group E received esmolol infusion while Group S received the same volume of saline infusion. Demographic data, haemodynamics, amount of isoflurane used, end-tidal isoflurane concentration, postoperative pain score and total dose of morphine consumed in immediate postoperative period of 30 min were analyzed by using appropriate statistical tests. Value of P<0.05 was considered significant and P<0.001 as highly significant. Results: The two groups were comparable with respect to age, weight, ASA physical status, duration of surgery and amount of isoflurane used during anaesthesia. Assessment of postoperative pain was assessed by Visual Analogue Scale (VAS which showed significant difference at 30 min. The total dose of morphine consumption was significantly less (P<0.05 in Group E for relief of postoperative pain. Conclusions: We conclude that in light of depth of anaesthesia monitor esmolol has no effect on requirement of isoflurane, but it decreases the postoperative pain as well as postoperative requirement of morphine without increasing the risk of awareness.

    2015-05-01

    Academic achievement has been found to have a pervasive and substantial impact on a wide range of developmental outcomes and has also been implicated in the critical transition from adolescence into early adulthood. Previous research has revealed that self-reported grades tend to diverge from official transcript grade point average (GPA) scores, with students being more likely to report inflated scores. Making use of a sample of monozygotic twin (N = 282 pairs), dizygotic twin (N = 441 pairs), and full sibling (N = 1,757 pairs) pairs from the National Longitudinal Study of Adolescent Health (Add Health; 65 % White; 50 % male; mean age = 16.14), the current study is the first to investigate the role that genetic and environmental factors play in misreporting grade information. A comparison between self-reported GPA (mean score of 2.86) and official transcript GPA scores (mean score of 2.44) revealed that self-reported scores were approximately one-half letter grade greater than official scores. Liability threshold models revealed that additive genetic influences explained between 40 and 63 % of the variance in reporting inflated grades and correctly reporting GPA, with the remaining variance explained by the nonshared environment. Conversely, 100 % of the variance in reporting deflated grade information was explained by nonshared environmental influences. In an effort to identify specific nonshared environmental influences on reporting accuracy, multivariate models that adequately control for genetic influences were estimated and revealed that siblings with lower transcript GPA scores were significantly less likely to correctly report their GPA and significantly more likely to report inflated GPA scores. Additional analyses revealed that verbal IQ and self-control were not significantly associated with self-reported GPA accuracy after controlling for genetic influences. These findings indicate that previous studies that implicate verbal IQ and self

    Full Text Available The objective of this work was to evaluate the influence of low-stress handling (LSH on reactivity score and pregnancy rate during fixed-time artificial insemination (FTAI for extensively raised Nellore cows. Multiparous cows (n = 126 were randomly allocated into two groups: G1 (n = 66 and G2, the control group (n = 60. Group G1 was subjected to LSH, in which the animals were handled in a calm and quiet manner, without loud noises or physical aggression, using the point of balance, respecting the flight zone and using flags to supplement handling. Group G2 was handled following the typical procedure, with yelling, kicking and the use of electric prods and sticks. On D0, D8 and D10, FTAI was performed in both groups. Reactivity was scored on D0, D8 and D10 at the squeeze chute, based on the tension score, breathing score, and bellowing score. Using the three criteria above, the reactivity scores were defined as follows: R1 (calm; R2 (slightly reactive; R3 (moderately reactive; R4 (reactive; and R5 (highly reactive. Thirty-five days after artificial insemination, pregnancy was determined using ultrasonography. There was no significant correlation between reactivity score and pregnancy rate in each group or between the pregnancy rates in both groups. However, there was a statistically significant difference between the G1 and G2 groups with regard to reactivity score (1.62±0.05 vs. 2.12±0.07. Low-stress handling influenced reactivity but did not affect pregnancy rate in extensively raised Nellore cows subjected to FTAI.

    The influence of perioperative transfusion (PT) on outcome following surgery for gastric cancer (GC) remains controversial, with randomized trials lacking and observational series confounded by patient risk factors. This analysis determines the association between reception of leukocyte-depleted blood products and post-operative survival for GC.Data from 610 patients who underwent curative surgery for GC in a German tertiary care clinic from 2001 to 2013 were included. Kaplan-Meier survival curves and Cox proportional hazards regression were applied to determine the association of PT and clinical and patient risk factors for overall and relapse-free survival. Propensity score analysis was performed to adjust for observational biases in reception of PT.Higher Union International Contre le Cancer/American Joint Committee on Cancer (UICC/AJCC)-stages (P female gender (P = 0.03). In the adjusted propensity score weighted analysis, PT remained associated with an increased risk of death (hazard ratio (HR): 1.31, 95% CI: 1.01-1.69, P = 0.04).Because of the association of PT with negative influence on patient survival following resection for GC, risks from application of blood products should be weighed against the potential benefits.

    Full Text Available Abstract Background Political conflicts in Bangkok, Thailand have caused mass casualties, especially the latest event April 10, 2010, in which many military personnel were injured. Most of them were transferred to Phramongkutklao Hospital, the largest military hospital in Thailand. The current study aimed to assess factors influencing Injury Severity Score (ISS regarding Thai military personnel injured in the mass casualty incident (MCI April 10, 2010. Methods A total of 728 injured soldiers transferred to Phramongkutklao Hospital were reviewed. Descriptive statistics was used to display characteristics of the injuries, relationship between mechanism of injury and injured body regions. Multiple logistic regressions were used to calculate the adjusted odds ratio (adjusted OR of ISS comparing injured body region categories. Results In all, 153 subjects defined as major data category were enrolled in this study. Blast injury was the most common mechanism of injury (90.2%. These victims displayed 276 injured body regions. The most common injured body region was the extremities (48.5%. A total of 18 patients (11.7% had an ISS revealing more than 16 points. Three victims who died were expected to die due to high Trauma and Injury Severity Score (TRISS. However, one with high TRISS survived. Factors influencing ISS were age (p = 0.04, abdomen injury (adjusted OR = 29.9; 95% CI, 5.8-153.5; P P P Conclusions Blast injury was the most common mechanism of injury among Thai military personnel injured in the MCI April 10, 2010. Age and injured body region such as head & neck, chest and abdomen significantly influenced ISS. These factors should be investigated for effective medical treatment and preparing protective equipment to prevent such injuries in the future.

    2012-01-01

    To validate the recently proposed pediatric severity score (PSS) for sickle cell disease (SCD), we retrospectively assembled clinical data from a cohort of 122 patients with SCD (105 S/S or S/β(0) -thal. and 17 S/C) followed up for at least 2 years. Besides age and α- and β-globin genotypes, four new parameters were also tested against the PSS: duration of data assembly, neonatal screening, use of transcranial Doppler ultrasound to prevent vasculopathies and β-globin gene cluster haplotype. Once again, the PSS clearly differentiated patients by their β-globin genotype (P=0.004) but not by their age during data assembly (P=0.159). But, surprisingly, alpha-gene deletions were not associated with a lower PSS (P=0.604), possibly reflecting the opposite effects of α-thalassemia on global SCD severity. As for the newly tested parameters, the PSS appeared not to be influenced by the duration of data assembly (P=0.071) and neonatal screening (P=0.678) but rather by the introduction of transcranial Doppler ultrasound (P=0.006). Moreover, the Senegal haplotype at the homozygous state may be associated with a lower PSS. Methodologically, our data globally confirm the usefulness of the PSS to identify major etiological factors of SCD gravity. Nevertheless, the score is surely underestimated for patients who have been switched to a chronic therapy before the main SCD complications. Biologically, our study questions about the exact influence of α-thalassemia on global SCD severity. PMID:21910753

    Directory of Open Access Journals (Sweden)

    Jintao Lu

    2014-11-01

    Full Text Available A detailed study and analysis of previous research has been carried out to illustrate the relationships between a range of environmental emergencies, and their effects on the emotional state of the rescuers involved in responding to them, by employing Pub Med, Science Direct, Web of Science, Google Scholar, CNKI and Scopus for required information with the several keywords "emergency rescue", "occupational safety", "natural disaster", "emotional management". The effect of the rescuers' emotion on their occupational safety and immediate and long-term emotional behavior is then considered. From these considerations, we suggested four research propositions related to the emotional effects at both individual and group levels, and to the responsibilities of emergency response agencies in respect of ensuring the psychological and physical occupational safety of rescuers during and after environmental emergencies. An analysis framework is proposed which could be used to study the influence paths of these different aspects of emotional impact on a range of occupational safety issues for rescue workers. The authors believe that the conclusions drawn in this paper can provide a useful theoretical reference for decision-making related to the management and protection of the occupational safety of rescuers responding to natural disasters and environmental emergencies.

    Most previous studies have been single case reports, and studies with large samples are presently lacking. In addition, no studies have investigated the associations between the clinical characteristics and prognosis of hepatoid adenocarcinoma of the stomach (HAS).The aim of this study was to explore the associations of different clinical characteristics with the ages, serum alpha-fetoprotein (AFP) levels, and survival times of HAS patients.The present study was conducted using the CBM disc, HowNet, Wanfang and VIP data resource systems, and PubMed. According to the PRISMA Flow Diagram, certain case reports from the same center, those that did not provide patient age or sex, and those that did not report serum AFP levels or AFP immunohistochemistry results were excluded. A total of 131 relevant articles, including 124 case reports, 5 reviews, and 2 postgraduate Master's theses, were reported in the above-mentioned five databases. We applied inclusion criteria to case reports on the clinical characteristics and prognosis of HAS, which resulted in the ultimate inclusion of 180 patients from 62 case reports for statistical analyses.The main finding was that the age of the men was significantly higher than that of the women (P = 0.004). In addition, the serum AFP levels of the participants with antral disease were significantly higher than those with nonantral disease (P = 0.001). The median serum AFP levels and survival times significantly differed among the patients with the three lesion types (P = 0.001 and 0.019, respectively). The serum AFP levels of the participants with ulcerative-upheaval-type tumors and purely ulcerative tumors were significantly higher than those with upheaval-type tumors (P = 0.000 and 0.017, respectively). In addition, the serum AFP levels of the participants with ulcerative-upheaval-type tumors were significantly higher than those with ulcerative-type tumors (P = 0.019), and their survival time was also significantly

    Full Text Available The five viscera score (FVS is a diagnostic scale for traditional Chinese medicine (TCM. The purposes of current study are to elucidate the characteristics of FVS obtained from middle-aged to elderly individuals and to investigate the validity of FVS using biological medical data of middle-aged and elderly individuals. Structural equation modeling (SEM was used to conduct assessments between FVS and medical data. Eighty men and 99 women participated in this study, whose mean ages (SD were 58 ± 7 years in both genders showing no significant difference. FVS of women was significantly higher than that of men in the spleen of the 50s (P=0.019 and liver of the 60s age group (P=0.030. By SEM, the following biomedical factors were found to influence viscera: gender, diastolic blood pressure, and HDL-C for the liver; GLU, GOT, and γ-GTP for the spleen; age, BMI, and HCRP for the lungs; and HbA1c and creatinine clearance for the kidneys. These results provide objective evidence that FVS can be used for TCM diagnosis in middle-aged and elderly individuals.

    Full Text Available It has been possible to realize the significant contribution of entrepreneurs to the economy, given its ability to create jobs, provide new products, as well as establishing networks of small businesses. This can be verified in the importance given to the study of entrepreneurship worldwide. Evidence of this is the Global Entrepreneurship Monitor (GEM project, which booted in 1999, a partnership with London Business School and Babson College - UK, initially considered ten countries and now are 85 (GEM, 2012. We can realize the growing interest on the subject in academic environmentalist. In order to undertake the study of behavior has been gaining momentum. Many authors describe the Enterprising as individuals who have specific characteristics that differentiate them from others. In addition there has been increasing interest in entrepreneurship, a topic that has been gaining attention in the literature, reflected in the increasing number of publications on the subject. With the U.S., this paper aims to develop a meta-analysis of articles published in EnANPAD on entrepreneurial behavior in the period between 2004 and 2008, and identify the influence of international podução. Looking from this, to review the issue in order to present a theoretical map of the paths which Brazilian researchers have followed in the search for understanding of the topic, as well as identify possible inflência international publications in the national production on the subject.

    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.

  14. 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...

    Zeyner, A; Romanowski, K; Vernunft, A; Harris, P; Kienzle, E

    2014-04-01

    Based on a series of exercise tests which included the estimation of sweat losses, this article proposes a novel sweat scoring system for exercising horses. This provides a practical estimate of individual animal exercise-induced sweat losses, based on visible appearance of sweat on the coat after work, which takes into account the effect of various influencing factors. In terms of accuracy and flexibility, the score seems to provide advantages over estimates based on current general recommendations from reference books. Additional studies are needed to validate this scoring system and its use under more diverse situations. PMID:23534876

  19. Looking to score: the dissociation of goal influence on eye movement and meta-attentional allocation in a complex dynamic natural scene.

    Directory of Open Access Journals (Sweden)

    Shuichiro Taya

    Full Text Available Several studies have reported that task instructions influence eye-movement behavior during static image observation. In contrast, during dynamic scene observation we show that while the specificity of the goal of a task influences observers' beliefs about where they look, the goal does not in turn influence eye-movement patterns. In our study observers watched short video clips of a single tennis match and were asked to make subjective judgments about the allocation of visual attention to the items presented in the clip (e.g., ball, players, court lines, and umpire. However, before attending to the clips, observers were either told to simply watch clips (non-specific goal, or they were told to watch the clips with a view to judging which of the two tennis players was awarded the point (specific goal. The results of subjective reports suggest that observers believed that they allocated their attention more to goal-related items (e.g. court lines if they performed the goal-specific task. However, we did not find the effect of goal specificity on major eye-movement parameters (i.e., saccadic amplitudes, inter-saccadic intervals, and gaze coherence. We conclude that the specificity of a task goal can alter observer's beliefs about their attention allocation strategy, but such task-driven meta-attentional modulation does not necessarily correlate with eye-movement behavior.

    Directory of Open Access Journals (Sweden)

    V. Paoletti

    2012-07-01

    Full Text Available Shear wave velocities have a fundamental role in connection with the mitigation of seismic hazards, as their low values are the main causes of site amplification phenomena and can significantly influence the susceptibility of a territory to seismic-induced landslides. The shear wave velocity (Vs and modulus (G of each lithological unit are influenced by factors such as the degree of fracturing and faulting, the porosity, the clay amount and the precipitation, with the latter two influencing the unit water content. In this paper we discuss how these factors can affect the Vs values and report the results of different analyses that quantify the reduction in the rock Vs and shear modulus values connected to the presence of clay and water. We also show that significant results in assessing seismic-induced slope failure susceptibility for land planning targets could be achieved through a careful evaluation, based only on literature studies, of the geo-lithological and geo-seismic features of the study area.

    2015-11-01

    The aim of this study was to evaluate the influence of the geometrical detail of the DNA on nanodosimetric parameters of track structure induced by protons and alpha particles of different energies (LET values ranging from 1 to 162.5~\\text{keV}~μ {{\\text{m}}-1} ) as calculated by Geant4-DNA Monte Carlo simulations. The first geometry considered consisted of a well-structured placement of a realistic description of the DNA double helix wrapped around cylindrical histones (GeomHist) forming a 18 kbp-long chromatin fiber. In the second geometry considered, the DNA was modeled as a total of 1800 ten bp-long homogeneous cylinders (2.3 nm diameter and 3.4 nm height) placed in random positions and orientations (GeomCyl). As for GeomHist, GeomCyl contained a DNA material equivalent to 18 kbp. Geant4-DNA track structure simulations were performed and ionizations were counted in the scoring volumes. For GeomCyl, clusters were defined as the number of ionizations (ν) scored in each 10 bp-long cylinder. For GeomHist, clusters of ionizations scored in the sugar-phosphate groups of the double-helix were revealed by the DBSCAN clustering algorithm according to a proximity criteria among ionizations separated by less than 10 bp. The topology of the ionization clusters formed using GeomHist and GeomCyl geometries were compared in terms of biologically relevant nanodosimetric quantities. The discontinuous modeling of the DNA for GeomCyl led to smaller cluster sizes than for GeomHist. The continuous modeling of the DNA molecule for GeomHist allowed the merging of ionization points by the DBSCAN algorithm giving rise to larger clusters, which were not detectable within the GeomCyl geometry. Mean cluster size (m1) was found to be of the order of 10% higher for GeomHist compared to GeomCyl for LET <15~\\text{keV}~μ {{\\text{m}}-1} . For higher LETs, the difference increased with LET similarly for protons and alpha particles. Both geometries showed the same relationship

  4. Tracking Multiple Topics for Finding Interesting Articles

    Pon, R K; Cardenas, A F; Buttler, D J; Critchlow, T J

    2007-02-15

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

  5. Long-term trends in tourism climate index scores for 40 stations across Iran: the role of climate change and influence on tourism sustainability

    Tourism is a rapidly growing international sector and relies intrinsically on an amenable climate to attract visitors. Climate change is likely to influence the locations preferred by tourists and the time of year of peak travel. This study investigates the effect of climate change on the Tourism Climate Index (TCI) for Iran. The paper first calculates the monthly TCI for 40 cities across Iran for each year from 1961 to 2010. Changes in the TCI over the study period for each of the cities are then explored. Increases in TCI are observed for at least one station in each month, whilst for some months no decreases occurred. For October, the maximum of 45 % of stations demonstrated significant changes in TCI, whilst for December only 10 % of stations demonstrated change. The stations Kashan, Orumiyeh, Shahrekord, Tabriz, Torbat-e-Heidarieh and Zahedan experienced significant increases in TCI for over 6 months. The beginning of the change in TCI is calculated to have occurred from 1970 to 1980 for all stations. Given the economic dependence on oil exports, the development of sustainable tourism in Iran is of importance. This critically requires the identification of locations most suitable for tourism, now and in the future, to guide strategic investment.

    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.

  19. Vinardo: A Scoring Function Based on Autodock Vina Improves Scoring, Docking, and Virtual Screening

    Science.gov (United States)

    Villarreal, Marcos A.

    2016-01-01

    Autodock Vina is a very popular, and highly cited, open source docking program. Here we present a scoring function which we call Vinardo (Vina RaDii Optimized). Vinardo is based on Vina, and was trained through a novel approach, on state of the art datasets. We show that the traditional approach to train empirical scoring functions, using linear regression to optimize the correlation of predicted and experimental binding affinities, does not result in a function with optimal docking capabilities. On the other hand, a combination of scoring, minimization, and re-docking on carefully curated training datasets allowed us to develop a simplified scoring function with optimum docking performance. This article provides an overview of the development of the Vinardo scoring function, highlights its differences with Vina, and compares the performance of the two scoring functions in scoring, docking and virtual screening applications. Vinardo outperforms Vina in all tests performed, for all datasets analyzed. The Vinardo scoring function is available as an option within Smina, a fork of Vina, which is freely available under the GNU Public License v2.0 from http://smina.sf.net. Precompiled binaries, source code, documentation and a tutorial for using Smina to run the Vinardo scoring function are available at the same address. PMID:27171006

    Full Text Available Abstract Background Rapid identification of subject experts for medical topics helps in improving the implementation of discoveries by speeding the time to market drugs and aiding in clinical trial recruitment, etc. Identifying such people who influence opinion through social network analysis is gaining prominence. In this work, we explore how to combine named entity recognition from unstructured news articles with social network analysis to discover opinion leaders for a given medical topic. Methods We employed a Conditional Random Field algorithm to extract three categories of entities from health-related new articles: Person, Organization and Location. We used the latter two to disambiguate polysemy and synonymy for the person names, used simple rules to identify the subject experts, and then applied social network analysis techniques to discover the opinion leaders among them based on their media presence. A network was created by linking each pair of subject experts who are mentioned together in an article. The social network analysis metrics (including centrality metrics such as Betweenness, Closeness, Degree and Eigenvector are used for ranking the subject experts based on their power in information flow. Results We extracted 734,204 person mentions from 147,528 news articles related to obesity from January 1, 2007 through July 22, 2010. Of these, 147,879 mentions have been marked as subject experts. The F-score of extracting person names is 88.5%. More than 80% of the subject experts who rank among top 20 in at least one of the metrics could be considered as opinion leaders in obesity. Conclusion The analysis of the network of subject experts with media presence revealed that an opinion leader might have fewer mentions in the news articles, but a high network centrality measure and vice-versa. Betweenness, Closeness and Degree centrality measures were shown to supplement frequency counts in the task of finding subject experts. Further

  5. Measuring the Interestingness of Articles in a Limited User Environment

    Search engines, such as Google, assign scores to news articles based on their relevancy to a query. However, not all relevant articles for the query may be interesting to a user. For example, if the article is old or yields little new information, the article would be uninteresting. Relevancy scores do not take into account what makes an article interesting, which varies from user to user. Although methods such as collaborative filtering have been shown to be effective in recommendation systems, in a limited user environment, there are not enough users that would make collaborative filtering effective. A general framework, called iScore, is presented for defining and measuring the 'interestingness' of articles, incorporating user-feedback. iScore addresses various aspects of what makes an article interesting, such as topic relevancy, uniqueness, freshness, source reputation, and writing style. It employs various methods to measure these features and uses a classifier operating on these features to recommend articles. The basic iScore configuration is shown to improve recommendation results by as much as 20%. In addition to the basic iScore features, additional features are presented to address the deficiencies of existing feature extractors, such as one that tracks multiple topics, called MTT, and a version of the Rocchio algorithm that learns its parameters online as it processes documents, called eRocchio. The inclusion of both MTT and eRocchio into iScore is shown to improve iScore recommendation results by as much as 3.1% and 5.6%, respectively. Additionally, in TREC11 Adaptive Filter Task, eRocchio is shown to be 10% better than the best filter in the last run of the task. In addition to these two major topic relevancy measures, other features are also introduced that employ language models, phrases, clustering, and changes in topics to improve recommendation results. These additional features are shown to improve recommendation results by iScore by

    2014-01-01

    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.

    The International Classification of Sleep Disorders (ICSD-2) has separated sleep-related movement disorders into simple, repetitive movement disorders (such as periodic limb movements in sleep [PLMS], sleep bruxism, and rhythmic movement disorder) and parasomnias (such as REM sleep behavior disorder and disorders of partial arousal, e.g., sleep walking, confusional arousals, night terrors). Many of the parasomnias are characterized by complex behaviors in sleep that appear purposeful, goal directed and voluntary but are outside the conscious awareness of the individual and therefore inappropriate. All of the sleep-related movement disorders described here have specific polysomnographic findings. For the purposes of developing and/or revising specifications and polysomnographic scoring rules, the AASM Scoring Manual Task Force on Movements in Sleep reviewed background literature and executed evidence grading of 81 relevant articles obtained by a literature search of published articles between 1966 and 2004. Subsequent evidence grading identified limited evidence for reliability and/or validity for polysomnographic scoring criteria for periodic limb movements in sleep, REM sleep behavior disorder, and sleep bruxism. Published scoring criteria for rhythmic movement disorder, excessive fragmentary myoclonus, and hypnagogic foot tremor/alternating leg muscle activation were empirical and based on descriptive studies. The literature review disclosed no published evidence defining clinical consequences of excessive fragmentary myoclonus or hypnagogic foot tremor/alternating leg muscle activation. Because of limited or absent evidence for reliability and/or validity, a standardized RAND/UCLA consensus process was employed for recommendation of specific rules for the scoring of sleep-associated movements.

  19. 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.

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

    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.

    The treatment of cattle pain often relies upon veterinarians. The aim of this study was to qualify the influence of veterinarians skills, attitudes, and empathy on cattle pain assesment and consequently disbudding pain management. A web-based questionnaire was sent to Finnish veterinary students in either the preclinical or clinical stage, and also to production-animal practice oriented veterinarians. The questionnaire recorded demographics, statements of opinions, pain scoring of cattle conditions and procedures. Empathy towards humans (Interpersonal Reactivity Index, IRI) and reworded IRI to measure empathy towards animals were also covered. The overall response rate was approximately 40%. The association between pain and empathy scores were analyzed by Pearsońs correlation, and the factors affecting pain scores and empathy towards animals analyzed using linear models. The need for pain medication of calves during disbudding was well recognized and the intention to treat such pain was very common. Higher mean scores for cattle pain were associated with greater empathy towards humans. On average, respondents' empathy towards animals was greater than towards humans, and was associated with respondents' empathy towards humans, family size and attachment to family pet. PMID:24685101

    2012-04-01

    Full Text Available In this introduction to the Special Issue on cognitive polyphasia, we make an initial attempt at clarifying some aspects of this concept by proposing two developmental perspectives that provide an interesting explanation for the genesis of cognitive polyphasia and its persistence in contemporary societies: * In the first, a diachronic perspective, cognition is viewed as being influenced by the social, political and economic arrangements found in different societies. It is argued that to specific societies correspond different types of knowledge but that, contrary to the conventional view in social sciences, the progression from one society to another, and their respective types of knowledge, is not completely straightforward. One can observe reminiscences of ‘old’ types of knowledge in modern societies, one way of understanding the idea of cognitive polyphasia. * In the second, a synchronic perspective, the various functions played by different types of knowledge are emphasised and one can see why individuals, groups and societies may want to draw on a plurality of types of knowledge to make sense of their environment and fulfil different objectives. Here, cognitive polyphasia describes the use of different types of knowledge as a result of the different characteristics they have and the different roles they play. We conclude this introduction by presenting the different papers that are comprised in this Special Issue and highlighting the contributions each of them makes to a better understanding of cognitive polyphasia.

    Full Text Available Orientation: The article discussed the importance of rigour in credit risk assessment.Research purpose: The purpose of this empirical paper was to examine the predictive performance of credit scoring systems in Taiwan.Motivation for the study: Corporate lending remains a major business line for financial institutions. 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.

    Full Text Available Abstract Background Osteoarthritis (OA involves changes in both bone and cartilage. These processes might be associated under some circumstances. This study investigated correlations between bone and cartilage degradation in patients with OA as a function of sex, Kellgren-Lawrence (KL score, Body Mass Index (BMI, oral salmon calcitonin (sCT treatment and diurnal variation. Methods This study was a 2-week, double-blind, double-dummy, randomized study including 37 postmenopausal women and 36 men, aged 57-75 years, with painful knee OA, and a KL-score of I - III. Subjects were allocated to one of three treatment arms: 0.6 mg or 0.8 mg oral sCT, or placebo given twice-daily for 14 days. Correlations between gender, KL score, or BMI and the bone resorption marker, serum C-terminal telopeptide of collagen type I (CTX-I, or the cartilage degradation marker, urine C-terminal telopeptide of collagen type II (CTX-II were investigated. Results At baseline, biomarkers indicated women with OA experienced higher bone and cartilage degradation than men. CTX-I levels were significantly higher, and CTX-II levels only marginally higher, in women than in men (p = 0.04 and p = 0.06, respectively. Increasing KL score was not correlated with bone resorption, but was significantly associated with the cartilage degradation CTX-II marker in both men and women (p = 0.007. BMI was significantly and negatively correlated to the bone resorption marker CTX-I, r = -0.40 (p = 0.002, but showed only a borderline positive correlation to CTX-II, r = 0.25 (p = 0.12. Before morning treatments on days 1 and 14, no correlation was seen between CTX-I and CTX-II in either the sCT or placebo group. However, oral sCT and food intake induced a clear correlation between these bone and cartilage degradation markers. Four hours after the first sCT dose on treatment days 1 and 14, a significant correlation (r = 0.71, p p = 0.02, but not on day 14. Conclusion Bone resorption was higher in

  17. Ligand Identification Scoring Algorithm (LISA)

    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

    Science.gov (United States)

    Kolahi, J; Khazaei, S

    2016-06-10

    Introduction Altmetrics is a new and emerging scholarly tool that measures online attention surrounding journal articles. Altmetric data resources include: policy documents, news outlets, blogs, online reference managers (eg Mendeley and CiteULike), post-publication peer-review forums (eg PubPeer and Publons), social media (eg Twitter, Facebook, Weibo, Google(+), Pinterest, Reddit), Wikipedia, sites running Stack Exchange (Q&A), and reviews on F1000 and YouTube.Methods To identify the top 50 dental articles in 2014, PubMed was searched using the following query "("2014/1/1"[PDAT]:"2014/12/31"[PDAT]) and jsubsetd[text]" in December, 2015. Consequently, all PubMed records were extracted and sent to Altmetric LLP (London, UK) as a CSV file for examination. Data were analysed by Microsoft Office Excel 2010 using descriptive statistics and charts.Results Using PubMed searches,15,132 dental articles were found in 2014. The mean Altmetric score of 50 top dental articles in 2014 was 69.5 ± 73.3 (95% CI: -74.14 to 213.14). The British Dental Journal (48%) and Journal of Dental Research (16%) had the maximum number of top articles. Twitter (67.13%), Mendeley (15.89%) and news outlets (10.92%) were the most popular altmetric data resources.Discussion Altmetrics are intended to supplement bibliometrics, not replace them. Altmetrics is a fresh and emerging arena for the dental research community. We believe that dental clinical practitioners, research scientists, research directors and journal editors must pay more attention to altmetrics as a new and rapid tool to measure the social impact of scholarly articles.

    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.

    Full Text Available Introduction. A family history of Alzheimer’s disease is a significant risk factor for its onset, but the genetic risk associated with possessing multiple risk alleles is still poorly understood. Methods. In a sample of 95 older adults (Mean age = 75.1, 64.2% female, we constructed a genetic risk score based on the accumulation of risk alleles in BDNF, COMT, and APOE. A neuropsychological evaluation and consensus determined cognitive status (44 nonimpaired, 51 impaired. Logistic regression was performed to determine whether the genetic risk score predicted cognitive impairment above and beyond that associated with each gene. Results. An increased genetic risk score was associated with a nearly 4-fold increased risk of cognitive impairment (OR = 3.824, P = .013 when including the individual gene polymorphisms as covariates in the model. Discussion. A risk score combining multiple genetic influences may be more useful in predicting late-life cognitive impairment than individual polymorphisms.

    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.

    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.

    Massidda, Myosotis; Calò, Carla M

    2012-01-01

    Scores in artistic gymnastics are subject to changes in the rules that occur each Olympic cycle as outlined in the Code of Points, because rules influence the composition of routines and therefore performance. The aim of this study was to identify the most important routine apparatus for success in a World competition. The data were the official results for the 478 gymnasts (262 men, 216 women) who competed in the 43rd Artistic Gymnastic World Championships in 2011 in Tokyo, Japan. The factors least influenced by the technical standard of competitors were performance scores on uneven bars and balance beam for women, and those on pommel horse for men. For uneven bars, balance beam, and pommel horse, scores were consistently good predictors of final standing. Our results suggest that high scores on these apparatus have a greater influence on overall performance than scores on the other apparatus, regardless of the competitors' standard. PMID:22845333

  13. Digital watermarking for the protection of music scores

    Science.gov (United States)

    Schmucker, Martin; Busch, Christoph; Pant, Anoop

    2001-08-01

    The need for protection mechanisms for multimedia content is widely recognized. In the past digital watermarking algorithms for images have been developed that provide a certain level of protection for colored or gray-scale images. Since classical raster-oriented watermarking algorithms do not satisfy the needs for symbol oriented music score images we present in this paper a solution that should give promising robustness of the watermark at minimal visibility impact. This solution respects the content of binary images and can be considered as a symbolic interpretation and modification of music scores. Some music symbols are used by changing their features for hiding an information string in a music score. The advantage is its robustness and invisibility. Regarding the invisibility a musician should under no circumstances be impeded in reading the music. One must even consider the fact of being influenced unconsciously. For example, it might be more difficult to concentrate on a music sheet if the symbols were changed invisibly. The most probable way of distributing music scores is the analog (paper) form. Music scores are copied and distributed. So watermarks should be readable even after multiple copy procedures. By choosing suitable features a blind detection of the watermark is possible.

  17. Journal ratings as predictors of articles quality in Arts, Humanities and Social Sciences: an analysis based on the Italian Research Evaluation Exercise [v1; ref status: indexed, http://f1000r.es/5d3

    Directory of Open Access Journals (Sweden)

    Andrea Bonaccorsi

    2015-07-01

    Full Text Available The aim of this paper is to understand whether the probability of receiving positive peer reviews is influenced by having published in an independently assessed, high-ranking journal: we eventually interpret a positive relationship among peer evaluation and journal ranking as evidence that journal ratings are good predictors of article quality. The analysis is based on a large dataset of over 11,500 research articles published in Italy in the period 2004-2010 in the areas of architecture, arts and humanities, history and philosophy, law, sociology and political sciences. These articles received a score by a large number of externally appointed referees in the context of the Italian research assessment exercise (VQR; similarly, journal scores were assigned in a panel-based independent assessment, which involved all academic journals in which Italian scholars have published, carried out under a different procedure. The score of an article is compared with that of the journal it is published in: more specifically, we first estimate an ordered probit model, assessing the probability for a paper of receiving a higher score, the higher the score of the journal; in a second step, we concentrate on the top papers, evaluating the probability of a paper receiving an excellent score having been published in a top-rated journal. In doing so, we control for a number of characteristics of the paper and its author, including the language of publication, the scientific field and its size, the age of the author and the academic status. We add to the literature on journal classification by providing for the first time a large scale test of the robustness of expert-based classification.

  18. Combination of scoring schemes for protein docking

    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.

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

    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

  5. Random Walk Picture of Basketball Scoring

    CERN Document Server

    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.

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.

    The all scores matrix of a grid graph is a matrix containing the optimal scores of paths from every vertex on the first row of the graph to every vertex on the last row. This matrix is commonly used to solve diverse string comparison problems. All scores matrices have the Monge property, and this was exploited by previous works that used all scores matrices for solving various problems. In this paper, we study an extension of grid graphs that contain an additional set of edges, called bridges...

    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.

  6. Lo Score: un algoritmo per investigare la Body Knowledge

    Directory of Open Access Journals (Sweden)

    Letizia Gioa Monda

    2015-03-01

    Full Text Available Both inside and outside theatre, body work is the first and principle aspect of work on the ‘self’. It is the first inescapable step in the path toward the aware action which in theatre is the “action in perception”, i.e. thinking-in-movement. This aware thought involves the whole background of the person. It is an action that arises only when the person is present and at the same time dynamically involved entirely in the environment: it is the perceptual consciousness that integrates the planning of the action with the execution of the same action. “Thinking-in-movement” is a dynamic process that is not possible to be codified: it is a language that asks to be experienced in order to be able to be understood and learned. Therefore, what is the Score? Is it a concept, a method of movement, or a digital tool? Perhaps it is each one of these things. The Score is an indispensable algorithm to read the dance that the human writes in order to obtain information, transfer them and so continue in the evolution of the body knowledge. The Score is the medium in which the human being structured tensions are shaped: i.e., an alternative site to understand the potential instigation of the human body and the organization of his residual actions. In this article I will read the score like a crystal: metaphor of the shaped dynamism innate in the expressive movement. I will explain how this crystal is the necessary channel to make sure the choreographic counterpoint can show up during the live performance. I will explore what this means for the choreographers involved in Motion Bank - William Forsythe, Deborah Hay, Jonathan Burrows and Matteo Fargion - analyzing the somatic connections between their dance-making and the score-creation.

    2004-12-01

    Full Text Available Abstract Background Uncertainty regarding comorbid illness, and ability to tolerate aggressive therapy has led to minimal enrollment of elderly cancer patients into clinical trials and often substandard treatment. Increasingly, comorbid illness scales have proven useful in identifying subgroups of elderly patients who are more likely to tolerate and benefit from aggressive therapy. Unfortunately, the use of such scales has yet to be widely integrated into either clinical practice or clinical trials research. Methods This article reviews evidence for the validity of the Charlson Comorbidity Index (CCI in oncology and provides a Microsoft Excel (MS Excel Macro for the rapid and accurate calculation of CCI score. The interaction of comorbidity and malignant disease and the validation of the Charlson Index in oncology are discussed. Results The CCI score is based on one year mortality data from internal medicine patients admitted to an inpatient setting and is the most widely used comorbidity index in oncology. An MS Excel Macro file was constructed for calculating the CCI score using Microsoft Visual Basic. The Macro is provided for download and dissemination. The CCI has been widely used and validated throughout the oncology literature and has demonstrated utility for most major cancers. The MS Excel CCI Macro provides a rapid method for calculating CCI score with or without age adjustments. The calculator removes difficulty in score calculation as a limitation for integration of the CCI into clinical research. The simple nature of the MS Excel CCI Macro and the CCI itself makes it ideal for integration into emerging electronic medical records systems. Conclusions The increasing elderly population and concurrent increase in oncologic disease has made understanding the interaction between age and comorbid illness on life expectancy increasingly important. The MS Excel CCI Macro provides a means of increasing the use of the CCI scale in clinical

Data were collected from 250 examinees using the “Many Uses Test” of DT. The most important finding involved the flexibility scores from both scoring methods. This was critical because semantic networks are based on conceptual structures, and thus a high SBA score should be highly correlated with the traditional flexibility score from DT tests. Results confirmed this correlation (r = .74. This supports the use of algorithmic scoring of DT. The nearly-immediate computation time required by SBA method may make it the method of choice, especially when it comes to moderate- and large-scale DT assessment investigations. Correlations between SBA scores and GPA were insignificant, providing evidence of the discriminant and construct validity of SBA scores.

  12. Finding and Recommending Scholarly Articles

    Kurtz, Michael J.; Henneken, Edwin A.

    2014-05-01

    The rate at which scholarly literature is being produced has been increasing at approximately 3.5 percent per year for decades. This means that during a typical 40 year career the amount of new literature produced each year increases by a factor of four. The methods scholars use to discover relevant literature must change. Just like everybody else involved in information discovery, scholars are confronted with information overload. Two decades ago, this discovery process essentially consisted of paging through abstract books, talking to colleagues and librarians, and browsing journals. A time-consuming process, which could even be longer if material had to be shipped from elsewhere. Now much of this discovery process is mediated by online scholarly information systems. All these systems are relatively new, and all are still changing. They all share a common goal: to provide their users with access to the literature relevant to their specific needs. To achieve this each system responds to actions by the user by displaying articles which the system judges relevant to the user's current needs. Recently search systems which use particularly sophisticated methodologies to recommend a few specific papers to the user have been called "recommender systems". These methods are in line with the current use of the term "recommender system" in computer science. We do not adopt this definition, rather we view systems like these as components in a larger whole, which is presented by the scholarly information systems themselves. In what follows we view the recommender system as an aspect of the entire information system; one which combines the massive memory capacities of the machine with the cognitive abilities of the human user to achieve a human-machine synergy.

  13. THE EFFICIENCY OF TENNIS DOUBLES SCORING SYSTEMS

    Directory of Open Access Journals (Sweden)

    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.

Iran J Child Neurol. 2014 Summer;8(3: 1-5.AbstractObjectiveInfantile spasm (IS is a convulsive disease characterized by brief, symmetric axial muscle contraction (neck, trunk, and/or extremities. IS is a type of seizure that was first described by West in 1841, who witnessed the seizure in his own son. West’s syndrome refers to the classic triad of spasms, characteristic EEG, and neurodevelopmental regression. Most cases involve flexors and extensors,but either of the types may be involved independently.IS, as its name implies, most often occurs during the first year of life with an incidence of approximately 1 per 2000-4000 live births. Most, but not all, patients with this disorder have severe EEG abnormalities; this pattern was originallyreferred to as hypsarrhythmia by Gibbs and Gibbs. Cases with known etiology or signs of brain damage are considered as symptomatic. The Overall prognosis of the disease is poor. Peak onset age of the epileptic syndrome is 3 to 7 months, which mainly occurs before 2 years of age in 93% of patients. Hypsarrhythmia is the EEG hallmark of IS, which comprised a chaotic, bilaterally asynchronous high-voltage polyspike, and slow wave discharges interspersed with multifocal spikes and slow waves.Etiological classification is as follows: 1 Symptomatic: with identifiable prenatal, perinatal, and postnatal causes with developmental delay at the presentation time; 2 Cryptogenic: unknown underlying cause, normal development at the onset of spasms, normal neurological exam and neuroimaging, and no abnormality in the metabolic evaluation; 3 Idiopathic: pure functional cerebral dysfunction with complete recovery, no residual dysfunction, normal neuroimaging and normal etiologic evaluation, and normal neurodevelopment.ReferencesInfantile Spasms.

    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.

    In this paper we test whether the disclosure of test scores has direct impacts on student performance, school composition and school inputs. We take advantage of the discontinuity on the disclosure rules of The National Secondary Education Examination (ENEM) run in Brazil by the Ministry of Education: In 2006 it was established that the 2005 mean score results would be disclosed for schools with ten or more students who took the exam in the previous year. We use a regression discontinuity des...

    A model combining student preferences for college with university admissions decisions is estimated to provide information on the role of test scores in the determination of post-secondary educational opportunities. In contrast to implications of much of the recent criticism of tests and their use, we find that scholastic aptitude test scores are more strongly related to student application and choice of college "quality" than to college admissions decisions. In addition, although there is a ...

    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...

    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.

    2016-04-01

    Full Text Available Emerging metrics based on article-level does not exclude traditional metrics based on citations to the journal, but complements them. Article-level metrics (ALMs provide a wide range of metrics about the uptake of an individual journal article by the scientific community after publication. They include citations, statistics of usage, discussions in online comments and social media, social bookmarking, and recommendations. In this editorial, the role of article level metrics in publishing scientific papers has been described. Article-Level Metrics (ALMs are rapidly emerging as important tools to quantify how individual articles are being discussed, shared, and used. Data sources depend on the tool, but they include classic metrics indicators depending on citations, academic social networks (Mendeley, CiteULike, Delicious and social media (Facebook, Twitter, blogs, and Youtube. The most popular tools used to apply this new metrics are: Public Library of Science - Article-Level Metrics, Altmetric, Impactstory and Plum Analytics. Journal Impact Factor (JIF does not consider impact or influence beyond citations count as this count reflected only through Thomson Reuters’ Web of Science® database. JIF provides indicator related to the journal, but not related to a published paper. Thus, altmetrics now becomes an alternative metrics for performance assessment of individual scientists and their contributed scholarly publications. Macedonian scholarly publishers have to work on implementing of article level metrics in their e-journals. It is the way to increase their visibility and impact in the world of science.

  20. Using family atopy scores to identify the risk of atopic dermatitis in infants

    2014-11-01

    Full Text Available Background Atopic dermatitis is the first manifestation of allergic disease in early life. Early interventions may prevent the development of allergy disease. Allergy trace cards have been used to identify the level of allergic risk, based on family atopy scores. Because environmental factors may also influence the development of atopic dermatitis, the usefulness of the allergy trace card needs to be reevaluated. Objective To compare the incidence of atopic dermatitis in infants aged 0-4 months with total family atopy scores of > 0 to those with scores of 0. Methods We conducted this cohort study from June 1, 2012 to December 31, 2012 at Sanglah Hospital, Denpasar. Family atopy score was tabulated from all pregnant woman in the Obstetric Outpatient Clinic and the Maternity Room. Subjects were divided into two groups based on their total family atopy score: those with scores > 0 and those with scores of 0. The appearance of atopic dermatitis symptoms in the infants were evaluated until they reached 4 months of age. The incidence of atopic dermatitis in two groups was compared using Chi-square test. Results The incidence of atopic dermatitis in this study was 10.9%. The group with total family atopy scores of 0 had a significantly higher incidence of atopic dermatitis than the group with scores > 0 (adjusted RR 22.5; 95%CI 8.8 to 57.0; P = 0.001. Conclusion The incidence of atopic dermatitis is higher in infants with total family atopy score > 0 and this group has a 22.5 times higher risk of atopic dermatitis compared to infants with total family atopy score of 0. Allergy trace cards are relevant in differentiating the risk of atopy with regards to development of atopic dermatitis. We suggest that family atopy scores be evaluated during antenatal care in order to limit the development of atopic dermatitis in infants. [Paediatr Indones. 2014;54:330-7.].

    Full Text Available At the present age, strategic planning is considered as an important and vital matter for organizations and formulating and implementing strategic plans and accurate parameters may result in organizations long-term superiority in competitive field. But, regarding that competitive factors of all organizations are not the same, formulating the strategy with a similar trend is unlikely to be effective and the prerequisite for success of any organization is to focus and pay attention to its own capacities and unique competitive advantages and to formulate strategies based on those capacities along with focusing on the weakness and threats points. This article presents a model integrated of the strategic planning process and balanced score card and considering four dimensions of the Balanced Score Card (BSC, it accomplishes the process of strategic planning in the fields of financial, customer, internal processes and growth and learning separately and then determines the position of an organization in each dimension. Therefore, the strength and weakness points of the organization are identified and the type of strategies needed for any dimension determined separately. With the aid of this model, top managers are able to determine the organization expects and goals of different sectors clearly and in line with the vision and strategy of organization and deliver to the managers and authorities of different sectors. The results of this model are the analysis of factors influencing on the strategy formulation, extraction of key dimensions, provision of the SWOT matrix for four-folds dimensions of BSC and the identification of organization situation in each dimension such that through basing it on, integrated strategies and operational plans will be formulated for the organization. In this survey, Isfahan Company of tile industry has been studied as a sample and the results of the model implementation for this company described in the text.

    Full Text Available OBJECTIVE: To examine the effects of reading exercise-related magazine articles (health, appearance, or control and the moderating effects of exercise self-identity on reasons for exercise and perceptions of attractiveness, among women in first year university. An additional purpose was to use a thought listing technique, the results of which were examined for evidence of internalization of the exercise-related messages. PARTICIPANTS: Female students in their first year of studies between September 2010 and April 2011 (N = 173; mean age = 19.31 years, mean body mass index = 22.01. METHODS: Participants read a health, appearance, or control article, listed thoughts, and completed questionnaires measuring reasons for exercising, physical self-perception, and exercise self-identity. RESULTS: Participants in the health condition rated exercise for health significantly higher than control condition participants. Participants with high exercise self-identity rated attractiveness as a reason for exercising significantly higher than low exercise self-identity participants in both the health and appearance conditions. Participants with higher internalization scores (i.e., accepted societal norms of appearance reported exercising for attractiveness reasons more so than participants with lower internalization scores. CONCLUSIONS: The good news is that health messages may be influential and result in wanting to exercise for health purposes. However, exercising for attractiveness was rated highly by participants with high exercise identity who read either the health or appearance articles. Health and appearance are not necessarily distinct concepts for female undergraduate students and the media may influence cited reasons for exercise.

    Full Text Available Event coreference detection is a task of automatically determining which fine-grained textual descriptions of events (e.g. sentences corefer. The task is important in organizing information in large collections of news articles, as extracted coreferring event mentions can provide the user with an overview of the events discussed in articles, and can also provide a glimpse into the factual data related to the events. In this article, we survey previous approaches to automatic event analysis, discuss theoretical considerations related to event coreference detection and also outline a motivation for experimenting with event coreference detection in the context of limited linguistic resources. In the experimental part of our work, we consider the task of event coreference detection in the subset of articles mentioning a specific person in a fixed publishing period, and we use the experiments to outline possible general factors that are influencing the results.

    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.

  5. Gambling scores for earthquake predictions and forecasts

    2010-04-01

    This paper presents a new method, namely the gambling score, for scoring the performance earthquake forecasts or predictions. Unlike most other scoring procedures that require a regular scheme of forecast and treat each earthquake equally, regardless their magnitude, this new scoring method compensates the risk that the forecaster has taken. Starting with a certain number of reputation points, once a forecaster makes a prediction or forecast, he is assumed to have betted some points of his reputation. The reference model, which plays the role of the house, determines how many reputation points the forecaster can gain if he succeeds, according to a fair rule, and also takes away the reputation points betted by the forecaster if he loses. This method is also extended to the continuous case of point process models, where the reputation points betted by the forecaster become a continuous mass on the space-time-magnitude range of interest. We also calculate the upper bound of the gambling score when the true model is a renewal process, the stress release model or the ETAS model and when the reference model is the Poisson model.

    Objective The aim of this study was to construct a prognostic index that predicts risk of relapse in women who have completed first-line treatment for ovarian cancer (OC). Methods A database of OC cases from 2000 to 2010 was interrogated for International Federation of Gynecology and Obstetrics stage, grade and histological subtype of cancer, preoperative and posttreatment CA-125 level, presence or absence of residual disease after cytoreductive surgery and on postchemotherapy computed tomography scan, and time to progression and death. The strongest predictors of relapse were included into an algorithm, the Risk of Ovarian Cancer Relapse (ROVAR) score. Results Three hundred fifty-four cases of OC were analyzed to generate the ROVAR score. Factors selected were preoperative serum CA-125, International Federation of Gynecology and Obstetrics stage and grade of cancer, and presence of residual disease at posttreatment computed tomography scan. In the validation data set, the ROVAR score had a sensitivity and specificity of 94% and 61%, respectively. The concordance index for the validation data set was 0.91 (95% confidence interval, 0.85-0.96). The score allows patient stratification into low (0.67) probability of relapse. Conclusions The ROVAR score stratifies patients according to their risk of relapse following first-line treatment for OC. This can broadly facilitate the appropriate tailoring of posttreatment care and support. PMID:25647256

    Full Text Available Background: The TIMI Score for ST-segment elevation myocardial infarction (STEMI was created and validated specifically for this clinical scenario, while the GRACE score is generic to any type of acute coronary syndrome. Objective: Between TIMI and GRACE scores, identify the one of better prognostic performance in patients with STEMI. Methods: We included 152 individuals consecutively admitted for STEMI. The TIMI and GRACE scores were tested for their discriminatory ability (C-statistics and calibration (Hosmer-Lemeshow in relation to hospital death. Results: The TIMI score showed equal distribution of patients in the ranges of low, intermediate and high risk (39 %, 27 % and 34 %, respectively, as opposed to the GRACE Score that showed predominant distribution at low risk (80 %, 13 % and 7%, respectively. Case-fatality was 11%. The C-statistics of the TIMI score was 0.87 (95%CI = 0.76 to 0.98, similar to GRACE (0.87, 95%CI = 0.75 to 0.99 - p = 0.71. The TIMI score showed satisfactory calibration represented by χ2 = 1.4 (p = 0.92, well above the calibration of the GRACE score, which showed χ2 = 14 (p = 0.08. This calibration is reflected in the expected incidence ranges for low, intermediate and high risk, according to the TIMI score (0 %, 4.9 % and 25 %, respectively, differently to GRACE (2.4%, 25% and 73%, which featured middle range incidence inappropriately. Conclusion: Although the scores show similar discriminatory capacity for hospital death, the TIMI score had better calibration than GRACE. These findings need to be validated populations of different risk profiles.

  8. The impact of a revised EQ-5D population scoring on preference-based utility scores in an inflammatory arthritis cohort.

    Adams, Roisin

    2012-02-01

    BACKGROUND AND OBJECTIVE: It is well established that there are problems with the EQ-5D. This is due to the original scoring methods used and how negative time trade-off (TTO) values were treated. A revised scoring method has been published. This article applies this to an inflammatory arthritis cohort. The objective is to examine the impact of a revised scoring system for the EQ-5D (UK) TTO on the utility estimates and in the case of rheumatoid arthritis, to explore the impact of using different utility metrics on the incremental cost-effectiveness ratio (ICER) results of an economic model. METHODS: A total of 504 patients with inflammatory arthritis were rescored using revised EQ-5D scoring, which uses an episodic random utility model to deal with negative TTO values. Differences in utility scores were compared and the new mapping coefficients were obtained. These were then used in an economic model to examine the impact on the ICER. RESULTS: In rheumatoid arthritis, the overall change is less for the revised EQ-5D scoring than with the original EQ-5D (TTO) but greater than the SF-6D: EQ-5D UK -0.22 (95% confidence interval [CI] -0.30 to -0.15), revised EQ-5D UK -0.16 (95% CI -0.21 to -0.10) and SF-6D -0.08 (95% CI -0.11 to -0.05). A similar trend is seen in the psoriatic arthritis group. The economic model produced different ICERs, when different utility measures were used; EQ-5D (TTO) euro42,402, SF-6D euro111,788, and revised EQ-5D (TTO) euro57,747. CONCLUSION: In the context of inflammatory arthritis, this article demonstrates that a revised scoring for EQ-5D may have a significant impact on utility estimates and on the output of the economic model.

    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.

    Full Text Available Introduction: Newborns should be evaluated immediately after birth and the traditional way of assessing is to use the Apgar score. The aim of this study was to estimate the Apgar score and evaluate the first 24 hour- clinical outcome of babies born at Yazd hospitals. Methods: In a descriptive cross-sectional study, Apgar score was assessed for 462 newborns at the 4 centers of Afshar, Madar, Kargar and Bahman of Yazd. 262 out of 462 babies were born by vaginal delivery and the other 200 babies were delivered by cesarean section. The data was analyzed by using both parametric and non parametric tests. Apgar score of 7 and less was considered as abnormal. Results: In this study, the type of delivery (cesarean section or vaginal delivery, method of anesthesia (epidural or general and gender of newborn had no impact on Apgar score, but prematurity, low birth weight, premature rupture of membranes, inadequate prenatal care and the level of maternal education had influence on reduction of the Apgar score. Those babies who were in good condition and were kept beside their mothers had the highest Apgar score. Conclusion: Apgar score is a useful measure to assess the general condition of the newborns at birth and for the prediction of their morbidity, mortality and neurologic impairment.

  15. Comparison of BISAP Score with Ranson Score in Determining the Severity of Acute Pancreatitis

    International Nuclear Information System (INIS)

    Objective:To determine the accuracy of BISAPscore in finding out the frequency of severity and mortality in patients with acute pancreatitis by comparing it with Ranson score. Study Design: Crosse-sectional study. Place and Duration of Study: Department of Surgery, Pakistan Institute of Medical Sciences, Islamabad, from April to December 2010. Methodology: A total of 80 patients who presented in emergency with acute pancreatitis were included by consecutive non probability sampling technique. Cases of acute pancreatitis were classified as mild or severe based on the organ failure criteria and/or local complications according to the Atlanta Symposium. All patients were scored according to both Ranson score and BISAP score. Results: Out of 80 patients, 35 (44 percentage) were males and 45 (56 percentage) were females. The mean age was 46.89 ± 15.75 years. Twenty five patients (31.25 percentage) were classified as severe acute pancreatitis and 3 patients (3.75 percentage) had evidence of pancreatic necrosis on CT scan. The duration of hospital stay was 1 - 54 days with a mean of 13.12 ± 12.83 days and mortality rate was 5 percentage. The number of patients with a BISAP score of =3 was 15 and Ranson score =3 was 25. The observed incidence of severe disease stratified by the BISAP score has (p greater than 0.001) and by Ranson score has (p greater than 0.001). In regards to mortality, patients having BISAP score =3 has p=0.003, while patients having Ranson score =3 has p=0.002, both are statistically significant. Conclusion:The newly proposed BISAPscore is a simple and accurate tool for severity stratification and is equally effective in finding out frequency of severity and in turns mortality in patients with acute pancreatitis as Ranson score.

  1. MEASURING SEMANTIC RELATEDNESS BETWEEN TWO WIKIPEDIA ARTICLES

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available This paper mainly focuses on estimating the relatedness and similarities between any two Wikipedia [1] articles. This paper describes various ways of determining the similarities. We hypothesize that by using some kind of properties of the Wikipedia articles, which can be internal or external, we can estimate the relatedness between Wikipedia articles. Each article is believed to have some kinds of internal properties and some external properties. Internal properties are those which are embedded inside the articles. It can be, for instance, have something to do with the content and text of the articles. External properties are those which are deduced or inferred from the articles. It can be, for example, the topic of the articles or even the closest distance between the two articles when plotted in a graph or in a category hierarchy.External properties include the properties associated with individual articles like topics (as mentioned,categories of the articles. Other techniques which are relevant when comparing the Wikipedia articles are cosine similarity, Jaccard similarity measure etc

  4. Measuring the Interestingness of News Articles

    Energy Technology Data Exchange (ETDEWEB)

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

  6. Comorbidity polypharmacy score and its clinical utility: A pragmatic practitioner′s perspective

    Directory of Open Access Journals (Sweden)

    Stanislaw P Stawicki

    2015-01-01

    Full Text Available Modern medical management of comorbid conditions has resulted in escalating use of multiple medications and the emergence of the twin phenomena of multimorbidity and polypharmacy. Current understanding of how the polypharmacy in conjunction with multimorbidity influences trauma outcomes is limited, although it is known that trauma patients are at increased risk for medication-related adverse events. The comorbidity-polypharmacy score (CPS is a simple clinical tool that quantifies the overall severity of comorbidities using the polypharmacy as a surrogate for the "intensity" of treatment necessary to adequately control chronic medical conditions. Easy to calculate, CPS is derived by counting all known pre-injury comorbid conditions and medications. CPS has been independently associated with mortality, increased risk for complications, lower functional outcomes, readmissions, and longer hospital stays. In addition, CPS may help identify older trauma patients at risk of post-emergency department undertriage. The goal of this article was to review and refine the rationale for CPS and to provide an evidence-based outline of its potential clinical applications.

  16. Use of Functional Ambulation Performance Score as measurement of gait ability: Review

    Directory of Open Access Journals (Sweden)

    Arnaud Gouelle, PhD

    2014-09-01

    Full Text Available Gait analysis systems are widely used for the assessment of gait disabilities and provide more accurate and detailed information than clinical tests. Scores and indexes have been proposed to summarize the large volume of data produced, each emphasizing different aspects of gait. Based on specific spatiotemporal gait parameters, the Functional Ambulation Performance Score (FAPS quantifies gait at a self-selected speed. Integrated within electronic walkways, the FAPS is commonly used for clinical evaluations and has been used in an increasing number of publications over the past few years. However, its use is sometimes distorted by misunderstandings of its composition and calculation, practical and/or conceptual limits, and even the meaning of the score. This technical report reviews the use of the FAPS for the evaluation of gait based on peer-reviewed articles and clinical experience and addresses important issues that must be considered for an optimal unbiased understanding and analysis of the score.

  4. Genesis of altmetrics or article-level metrics for measuring efficacy of scholarly communications: Current perspectives

    Directory of Open Access Journals (Sweden)

    Anup Kumar Das

    2014-01-01

    Full Text Available The article-level metrics (ALMs or altmetrics becomes a new trendsetter in recent times for measuring the impact of scientific publications and their social outreach to intended audiences. The popular social networks such as Facebook, Twitter, and Linkedin and social bookmarks such as Mendeley and CiteULike are nowadays widely used for communicating research to larger transnational audiences. In 2012, the San Francisco Declaration on Research Assessment got signed by the scientific and researchers communities across the world. This declaration has given preference to the ALM or altmetrics over traditional but faulty journal impact factor (JIF-based assessment of career scientists. JIF does not consider impact or influence beyond citations count as this count reflected only through Thomson Reuters′ Web of Science® database. Furthermore, JIF provides indicator related to the journal, but not related to a published paper. Thus, altmetrics now becomes an alternative metrics for performance assessment of individual scientists and their contributed scholarly publications. This paper provides a glimpse of genesis of altmetrics in measuring efficacy of scholarly communications and highlights available altmetric tools and social platforms linking altmetric tools, which are widely used in deriving altmetric scores of scholarly publications. The paper thus argues for institutions and policy makers to pay more attention to altmetrics based indicators for evaluation purpose but cautions that proper safeguards and validations are needed before their adoption.

  5. Stochastic sensitivity analysis using HDMR and score function

    Indian Academy of Sciences (India)

    Rajib Chowdhury; B N Rao; A Meher Prasad

    2009-12-01

    Probabilistic sensitivities provide an important insight in reliability analysis and often crucial towards understanding the physical behaviour underlying failure and modifying the design to mitigate and manage risk. This article presents a new computational approach for calculating stochastic sensitivities of mechanical systems with respect to distribution parameters of random variables. The method involves high dimensional model representation and score functions associated with probability distribution of a random input. The proposed approach facilitates first-and second-order approximation of stochastic sensitivity measures and statistical simulation. The formulation is general such that any simulation method can be used for the computation such as Monte Carlo, importance sampling, Latin hypercube, etc. Both the probabilistic response and its sensitivities can be estimated from a single probabilistic analysis, without requiring gradients of performance function. Numerical results indicate that the proposed method provides accurate and computationally efficient estimates of sensitivities of statistical moments or reliability of structural system.

    AIM: To implement a quick and simple test- rapid assessment faecal incontinence score(RAFIS) and show its reliability and validity.METHODS: From March 2008 through March 2010, we evaluated a total of 261 consecutive patients, including 53 patients with faecal incontinence. Demographic and comorbidity information was collected. In a single visit, patients were administered the RAFIS. The results obtained with the new score were compared with those of both Wexner score and faecal incontinence quality of life scale(FIQL) questionnaire. The patient withoutinfluence of the surgeon completed the test. The role of surgeon was explaining the meaning of each section and how he had to fill. Reliability of the RAFIS score was measured using intra-observer agreement and Cronbach’s alpha(internal consistency) coefficient. Multivariate analysis of the main components within the different scores was performed in order to determine whether all the scores measured the same factor and to conclude whether the information could be encompassed in a single factor. A sample size of 50 patients with faecal incontinence was estimated to be enough to detect a correlation of 0.55 or better at 5% level of significance with 80% power.RESULTS: We analysed the results obtained by 53 consecutive patients with faecal incontinence(median age 61.55 ± 12.49 years) in the three scoring systems. A total of 208 healthy volunteers(median age 58.41 ± 18.41 years) without faecal incontinence were included in the study as negative controls. Pearson’s correlation coefficient between "state" and "leaks" was excellent(r = 0.92, P < 0.005). Internal consistency in the comparison of "state" and "leaks" yielded also excellent correlation(Cronbach’s α = 0.93). Results in each score were compared using regression analysis and a correlation value of r = 0.98 was obtained with Wexner score. As regards FIQL questionnaire, the values of "r " for the different subscales of the questionnaire were: "lifestyle" r

  13. Citation pattern of newsworthy research articles

    Directory of Open Access Journals (Sweden)

    Manjari Manisha

    2015-01-01

    Full Text Available Popular science magazines cover research articles published in scholarly journals that the magazines perceive as having news value. Despite thousands of research articles being published in research journals, a very few get identified for coverage in popular science magazines, general magazines, and newspapers. Do research articles published in journals that are covered in popular science magazines receive higher citations? We hypothesize that newsworthy articles should receive higher citations as the newsworthiness can be a reflection of higher research value of the articles and also because of the visibility received by the articles owing to its coverage in popular science magazine. To empirically study the citedness, we identified 193 research articles and that were reported in New Scientist magazine in 2001. The characteristics of these articles including the citations received following coverage in New Scientist in 2001 were looked at. It was found that average citations per paper of articles covered in New Scientist was higher than the journal average for the year 2001 for 19 out of the 24 journals identified here.

    2016-06-01

    Despite abundant biological, biomechanical, and clinical research, return to sport after anterior cruciate ligament (ACL) injury remains a significant challenge. Residual rotatory knee laxity has been identified as one of the factors responsible for poor functional outcome. To improve and standardize the assessment of knee instability, a variety of instability scoring systems is available. Recently, devices to objectively quantify static and dynamic clinical exams have been developed to complement traditional subjective grading systems. These devices enable an improved evaluation of knee instability and possible associated injuries. This additional information may promote the development of new treatment algorithms and allow for individualized treatment. In this review, the different subjective laxity scores as well as complementary objective measuring systems are discussed, along with an introduction of injury to an individualized treatment algorithm.

    2011-01-01

    Problem statement: Stereotype threat has repeatedly been shown to depress womens scores on difficult math tests. An attempt to replicate these findings in China found no support for the stereotype threat hypothesis. Our math test was characterized as being personally important for the student participants, an atypical condition in most stereotype threat laboratory research. Approach: To evaluate the effects of this personal demand, we conducted three experiments. Results: ...

  18. When Can School Inputs Improve Test Scores?

    OpenAIRE

    2004-01-01

    Most studies fail to find an impact of school inputs on outcomes such as test scores. We argue that this might be a consequence of ignoring the possibility that households respond optimally to changes in school inputs and thus obscure the real effect of such provision on cognitive achievement. To incorporate the forward-looking behavior of households, we present a household optimization model relating household resources and cognitive achievement to school inputs. In this framework if househo...

  19. Deriving modified rankin scores from medical records

  1. A Social Approach to Microfinance Credit Scoring

    OpenAIRE

    Serrano-Cinca, Carlos; Gutiérrez-Nieto, Begoña; Nydia M. Reyes

    2013-01-01

    Microfinance Institutions (MFIs) provide loans to low income individuals. The credit scoring systems of MFIs, if they exist, are strictly financial. Although many MFIs consider the social impact of their loans, they do not incorporate formal systems to estimate this social impact. This paper proposes that their creditworthiness evaluations should be coherent with their social mission and should, accordingly, estimate the social impact of microcredit. Thus, a decision support system to facilit...

  7. Probabilistic Forecasts: Scoring Rules and Their Decomposition and Diagrammatic Representation via Bregman Divergences

    Directory of Open Access Journals (Sweden)

    Gareth Hughes

    2015-07-01

    Full Text Available A scoring rule is a device for evaluation of forecasts that are given in terms of the probability of an event. In this article we will restrict our attention to binary forecasts. We may think of a scoring rule as a penalty attached to a forecast after the event has been observed. Thus a relatively small penalty will accrue if a high probability forecast that an event will occur is followed by occurrence of the event. On the other hand, a relatively large penalty will accrue if this forecast is followed by non-occurrence of the event. Meteorologists have been foremost in developing scoring rules for the evaluation of probabilistic forecasts. Here we use a published meteorological data set to illustrate diagrammatically the Brier score and the divergence score, and their statistical decompositions, as examples of Bregman divergences. In writing this article, we have in mind environmental scientists and modellers for whom meteorological factors are important drivers of biological, physical and chemical processes of interest. In this context, we briefly draw attention to the potential for probabilistic forecasting of the within-season component of nitrous oxide emissions from agricultural soils.

    2016-03-01

    The prognosis of myelodysplastic syndromes (MDS) is currently estimated by using the revised International Prognostic Scoring System (IPSS-R). Several studies have shown that further refinement of prognostication for MDS can be achieved by adding flow cytometric parameters. However, widespread implementation of flow cytometry for the prognosis of MDS is hampered by complexity of the analysis. Therefore, the aim of this study was to construct a robust and practical flow cytometric score that could be implemented as a routine procedure. To achieve this, bone marrow aspirates of 109 MDS patients were analyzed by flow cytometry. A second cohort consisting of 103 MDS patients was used to validate the MDS flow cytometric score (MFS). The parameters forming the MFS were sideward light scatter and CD117 expression of myeloid progenitor cells and CD13 expression on monocytes. Three MFS risk categories were formed. Patients with MDS and intermediate MFS scores had significantly better overall survival (OS) compared with the patients with high MFS scores. The MFS further refined prognostication within the IPSS-R low-risk category, by identifying patients with worse OS in case of high MFS. In conclusion, a practical three parameter flow cytometric prognostic score was constructed enabling further refinement of prognostication of MDS. PMID:26503643

  19. What’s the Score? Walkable Environments and Subsidized Households

    Directory of Open Access Journals (Sweden)

    Young-Jae Kim

    2016-04-01

    Full Text Available Neighborhood walkability can influence individual health, social interactions, and environmental quality, but the relationships between subsidized households and their walkable environment have not been sufficiently examined in previous empirical studies. Focusing on two types of subsidized housing developments (Low-Income Housing Tax Credit (LIHTC and Public Housing (PH in Austin, Texas, this study evaluates the neighborhood walkability of place-based subsidized households, utilizing objectively measured Walk Score and walking-related built environment data. We also used U.S. Census block group data to account for the socio-demographic covariates. Based on various data, we employed bivariate and multivariate analyses to specify the relationships between subsidized households and their neighborhood walkable environment. The results of our bivariate analyses show that LIHTC households tend to be located in car-dependent neighborhoods and have more undesirable walking-related built environment conditions compared with non-LIHTC neighborhoods. Our regression results also represent that LIHTC households are more likely to be exposed to neighborhoods with low Walk Score, less sidewalk coverage, and more highways and major roads, while there are no significant associations for PH households. These findings imply that more attention and effort toward reducing the inequitable distributions of walkable neighborhood features supporting rather than hindering healthy lifestyles must be provided to subsidized households.

    2010-04-01

    Full Text Available A group of 147 shelter dogs were weighted and assigned a body condition score (BCS using a 9 point scale system, in order to evaluate the prevalence of obesity in the kennel. More than 60% of the animals showed a BCS³6 (overweight and obese and this condition was mainly attributed to an excess of carbohydrates and fat in the diet. In 67/147 dogs, a blood sample was drawn and the effects of BCS, age and time spent in the shelter were evaluated on biochemical parameters. Obese dogs showed significantly higher levels of triglycerides (P<0.01, while increasing BCS determined only an increasing non significant trend on cholesterol values. Age influenced creatinine (P<0.05 and the oldest dogs scoring BCS³6 registered significant higher NEFA (P<0.05 and CK (P=0.01 levels. Time spent in the shelter did not affect any parameter. The dogs’ metabolic condition reflects the need of taking more care of the quality of feed administered in the shelters to avoid the negative health effects caused by chronic obesity.

  2. Ranking of Wikipedia articles in search engines revisited: Fair ranking for reasonable quality?

    CERN Document Server

    Lewandowski, Dirk; 10.1002/asi.21423

    2011-01-01

    This paper aims to review the fiercely discussed question of whether the ranking of Wikipedia articles in search engines is justified by the quality of the articles. After an overview of current research on information quality in Wikipedia, a summary of the extended discussion on the quality of encyclopedic entries in general is given. On this basis, a heuristic method for evaluating Wikipedia entries is developed and applied to Wikipedia articles that scored highly in a search engine retrieval effectiveness test and compared with the relevance judgment of jurors. In all search engines tested, Wikipedia results are unanimously judged better by the jurors than other results on the corresponding results position. Relevance judgments often roughly correspond with the results from the heuristic evaluation. Cases in which high relevance judgments are not in accordance with the comparatively low score from the heuristic evaluation are interpreted as an indicator of a high degree of trust in Wikipedia. One of the sy...

  3. Neighborhood Social Context and Individual Polycyclic Aromatic Hydrocarbon Exposures Associated with Child Cognitive Test Scores.

    Childhood cognitive and test-taking abilities have long-term implications for educational achievement and health, and may be influenced by household environmental exposures and neighborhood contexts. This study evaluates whether age 5 scores on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R, administered in English) are associated with polycyclic aromatic hydrocarbon (PAH) exposure and neighborhood context variables including poverty, low educational attainment, low English language proficiency, and inadequate plumbing. The Columbia Center for Children's Environmental Health enrolled African-American and Dominican-American New York City women during pregnancy, and conducted follow-up for subsequent childhood health outcomes including cognitive test scores. Individual outcomes were linked to data characterizing 1-km network buffers around prenatal addresses, home observations, interviews, and prenatal PAH exposure data from personal air monitors. Prenatal PAH exposure above the median predicted 3.5 point lower total WPPSI-R scores and 3.9 point lower verbal scores; the association was similar in magnitude across models with adjustments for neighborhood characteristics. Neighborhood-level low English proficiency was independently associated with 2.3 point lower mean total WPPSI-R score, 1.2 point lower verbal score, and 2.7 point lower performance score per standard deviation. Low neighborhood-level educational attainment was also associated with 2.0 point lower performance scores. In models examining effect modification, neighborhood associations were similar or diminished among the high PAH exposure group, as compared with the low PAH exposure group. Early life exposure to personal PAH exposure or selected neighborhood-level social contexts may predict lower cognitive test scores. However, these results may reflect limited geographic exposure variation and limited generalizability. PMID:24994947

    Full Text Available Abstract: This article describes the advantages of using analytic proce­dure in speaking assessment. An analytic scoring guide, as compared to the impressionistic one, has a double function: as an instrument to mea­sure the learner's speaking proficiency and as a diagnostic procedure for remedial teaching. Thus, it provides reliable sources of information in the form of scores of the speaking components and can be used as feed-back for the teacher and learner to identify which component needs im­provement.

  6. Validation of new prognostic and predictive scores by sequential testing approach

    International Nuclear Information System (INIS)

    Background and Purpose: For practitioners, the question arises how their own patient population differs from that used in large-scale analyses resulting in new scores and nomograms and whether such tools actually are valid at a local level and thus can be implemented. A recent article proposed an easy-to-use method for the in-clinic validation of new prediction tools with a limited number of patients, a so-called sequential testing approach. The present study evaluates this approach in scores related to radiation oncology. Material and Methods: Three different scores were used, each predicting short overall survival after palliative radiotherapy (bone metastases, brain metastases, metastatic spinal cord compression). For each scenario, a limited number of consecutive patients entered the sequential testing approach. The positive predictive value (PPV) was used for validation of the respective score and it was required that the PPV exceeded 80%. Results: For two scores, validity in the own local patient population could be confirmed after entering 13 and 17 patients, respectively. For the third score, no decision could be reached even after increasing the sample size to 30. Conclusion: In-clinic validation of new predictive tools with sequential testing approach should be preferred over uncritical adoption of tools which provide no significant benefit to local patient populations. Often the necessary number of patients can be reached within reasonable time frames even in small oncology practices. In addition, validation is performed continuously as the data are collected.

  7. Measuring the Interestingness of Articles in a Limited User Environment Prospectus

    Energy Technology Data Exchange (ETDEWEB)

    Pon, R K

    2007-04-18

    Search engines, such as Google, assign scores to news articles based on their relevancy to a query. However, not all relevant articles for the query may be interesting to a user. For example, if the article is old or yields little new information, the article would be uninteresting. Relevancy scores do not take into account what makes an article interesting, which would vary from user to user. Although methods such as collaborative filtering have been shown to be effective in recommendation systems, in a limited user environment there are not enough users that would make collaborative filtering effective. I present a general framework for defining and measuring the ''interestingness'' of articles, called iScore, incorporating user-feedback including tracking multiple topics of interest as well as finding interesting entities or phrases in a complex relationship network. I propose and have shown the validity of the following: 1. Filtering based on only topic relevancy is insufficient for identifying interesting articles. 2. No single feature can characterize the interestingness of an article for a user. It is the combination of multiple features that yields higher quality results. For each user, these features have different degrees of usefulness for predicting interestingness. 3. Through user-feedback, a classifier can combine features to predict interestingness for the user. 4. Current evaluation corpora, such as TREC, do not capture all aspects of personalized news filtering systems necessary for system evaluation. 5. Focusing on only specific evolving user interests instead of all topics allows for more efficient resource utilization while yielding high quality recommendation results. 6. Multiple profile vectors yield significantly better results than traditional methods, such as the Rocchio algorithm, for identifying interesting articles. Additionally, the addition of tracking multiple topics as a new feature in iScore, can improve iScore

    Rajasekaran S

    2005-01-01

    Full Text Available Background: Gustilo′s grade IIIB classification includes a wide spectrum of injuries and is limited by high inter and intra observer error rates. Methods: A trauma score for grade IIIB open tibial fractures was devised to assess injury to three components; the covering tissues, musculotendinous units and bone with the severity scale in each category from one to five. Seven co-morbid conditions known to influence the prognosis were each given a score of two and summed up. Results : Ninety six consecutive Grade IIIB open injuries of tibia were prospectively evaluated. At 3-5 year follow up, of the 88 available, final score was less than five in 6 patients (Group I, between six and ten in 48 (Group II, eleven to fifteen in 29 (Group III and above 16 in five (Group IV. All patients in Group IV and one in Group III with score of fifteen underwent amputation. There was a significant difference (p less than 0.001 between the three groups in the requirement for flap (16.7,75&100 percent, time for union (16.3,24.9 &46.9, incidence of deep infection (0,22.9 &60.7 percent, number of surgical procedures (1.2,3.1 &6.3 and inpatient days (12.5,22.6 &59.4. A score of greater than three in any one component required special skills in management and interfered with healing of other structures. Conclusion: The scoring system was easy to apply and had a high degree of interobservor aggreement rate. This comprehensive score reliably prognosticates both limb salvage and outcome measures in severe open injuries of tibia.

  9. A comprehensive survey of retracted articles from the scholarly literature.

    Directory of Open Access Journals (Sweden)

    Michael L Grieneisen

    Full Text Available BACKGROUND: The number of retracted scholarly articles has risen precipitously in recent years. Past surveys of the retracted literature each limited their scope to articles in PubMed, though many retracted articles are not indexed in PubMed. To understand the scope and characteristics of retracted articles across the full spectrum of scholarly disciplines, we surveyed 42 of the largest bibliographic databases for major scholarly fields and publisher websites to identify retracted articles. This study examines various trends among them. RESULTS: We found, 4,449 scholarly publications retracted from 1928-2011. Unlike Math, Physics, Engineering and Social Sciences, the percentages of retractions in Medicine, Life Science and Chemistry exceeded their percentages among Web of Science (WoS records. Retractions due to alleged publishing misconduct (47% outnumbered those due to alleged research misconduct (20% or questionable data/interpretations (42%. This total exceeds 100% since multiple justifications were listed in some retraction notices. Retraction/WoS record ratios vary among author affiliation countries. Though widespread, only miniscule percentages of publications for individual years, countries, journals, or disciplines have been retracted. Fifteen prolific individuals accounted for more than half of all retractions due to alleged research misconduct, and strongly influenced all retraction characteristics. The number of articles retracted per year increased by a factor of 19.06 from 2001 to 2010, though excluding repeat offenders and adjusting for growth of the published literature decreases it to a factor of 11.36. CONCLUSIONS: Retracted articles occur across the full spectrum of scholarly disciplines. Most retracted articles do not contain flawed data; and the authors of most retracted articles have not been accused of research misconduct. Despite recent increases, the proportion of published scholarly literature affected by retraction

    Duchane, D.V.

    1981-05-29

    Super-smooth rounded or formed articles made of thermoplastic materials including various poly(methyl methacrylate) or acrylonitrile-butadiene-styrene copolymers are produced by immersing the articles into a bath, the composition of which is slowly changed with time. The starting composition of the bath is made up of at least one solvent for the polymer and a diluent made up of at least one nonsolvent for the polymer and optional materials which are soluble in the bath. The resulting extremely smooth articles are useful as mandrels for laser fusion and should be useful for a wide variety of other purposes, for example lenses.

  12. 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)

    Full Text Available PURPOSE: To test whether corneal hysteresis (CH and corneal resistance factor (CRF can discriminate between keratoconus and normal eyes and to evaluate whether the averages of two consecutive measurements perform differently from the one with the best waveform score (WS for diagnosing keratoconus. METHODS: ORA measurements for one eye per individual were selected randomly from 53 normal patients and from 27 patients with keratoconus. Two groups were considered the average (CH-Avg, CRF-Avg and best waveform score (CH-WS, CRF-WS groups. The Mann-Whitney U-test was used to evaluate whether the variables had similar distributions in the Normal and Keratoconus groups. Receiver operating characteristics (ROC curves were calculated for each parameter to assess the efficacy for diagnosing keratoconus and the same obtained for each variable were compared pairwise using the Hanley-McNeil test. RESULTS: The CH-Avg, CRF-Avg, CH-WS and CRF-WS differed significantly between the normal and keratoconus groups (p<0.001. The areas under the ROC curve (AUROC for CH-Avg, CRF-Avg, CH-WS, and CRF-WS were 0.824, 0.873, 0.891, and 0.931, respectively. CH-WS and CRF-WS had significantly better AUROCs than CH-Avg and CRF-Avg, respectively (p=0.001 and 0.002. CONCLUSION: The analysis of the biomechanical properties of the cornea through the ORA method has proved to be an important aid in the diagnosis of keratoconus, regardless of the method used. The best waveform score (WS measurements were superior to the average of consecutive ORA measurements for diagnosing keratoconus.

    The popular Biometric used to authenticate a person is Fingerprint which is unique and permanent throughout a person's life. A minutia matching is widely used for fingerprint recognition and can be classified as ridge ending and ridge bifurcation. In this paper we projected Fingerprint Recognition using Minutia Score Matching method (FRMSM). For Fingerprint thinning, the Block Filter is used, which scans the image at the boundary to preserves the quality of the image and extract the minutiae from the thinned image. The false matching ratio is better compared to the existing algorithm.

  17. Explaining the black-white gap in cognitive test scores: Toward a theory of adverse impact.

    2015-11-01

    In understanding the causes of adverse impact, a key parameter is the Black-White difference in cognitive test scores. To advance theory on why Black-White cognitive ability/knowledge test score gaps exist, and on how these gaps develop over time, the current article proposes an inductive explanatory model derived from past empirical findings. According to this theoretical model, Black-White group mean differences in cognitive test scores arise from the following racially disparate conditions: family income, maternal education, maternal verbal ability/knowledge, learning materials in the home, parenting factors (maternal sensitivity, maternal warmth and acceptance, and safe physical environment), child birth order, and child birth weight. Results from a 5-wave longitudinal growth model estimated on children in the NICHD Study of Early Child Care and Youth Development from ages 4 through 15 years show significant Black-White cognitive test score gaps throughout early development that did not grow significantly over time (i.e., significant intercept differences, but not slope differences). Importantly, the racially disparate conditions listed above can account for the relation between race and cognitive test scores. We propose a parsimonious 3-Step Model that explains how cognitive test score gaps arise, in which race relates to maternal disadvantage, which in turn relates to parenting factors, which in turn relate to cognitive test scores. This model and results offer to fill a need for theory on the etiology of the Black-White ethnic group gap in cognitive test scores, and attempt to address a missing link in the theory of adverse impact.

    Dietary components are important determinants of systemic inflammation, a risk factor for most chronic diseases. The Dietary Inflammatory Index (DII) was developed to assess dietary inflammatory potential. It was hypothesized that anti-inflammatory DII scores would be associated with "healthier" scores on other dietary indices. The Energy Balance Study is an observational study focusing on energy intake and expenditure in young adults; only baseline data were used for this analysis (n=430). The DII, as well as the Healthy Eating Index-2010 (HEI-2010), the Alternative Healthy Eating Index (AHEI), and the Dietary Approaches to Stop Hypertension Index (DASH) were calculated based on one to three 24-hour dietary recalls. General linear models were used to estimate least square means of the AHEI, HEI-2010, and DASH according to DII quartiles. Those with higher (ie, more proinflammatory) DII scores were more likely to be males, have less than a completed college education, and be younger. In addition, those with higher scores for cognitive restraint for eating or drive for thinness had lower (ie, anti-inflammatory) DII scores. Linear regression analyses indicated that as the DII increased, the AHEI, HEI-2010, and DASH dietary indices decreased (ie, became more unhealthy, all Pfactor for chronic disease. PMID:26923507

    Molecular biology and literature databases represent essential infrastructure for life science research. Effective integration of these data resources requires that there are structured cross-references at the level of individual articles and biological records. Here, we describe the current patterns of how database entries are cited in research articles, based on analysis of the full text Open Access articles available from Europe PMC. Focusing on citation of entries in the European Nucleotide Archive (ENA), UniProt and Protein Data Bank, Europe (PDBe), we demonstrate that text mining doubles the number of structured annotations of database record citations supplied in journal articles by publishers. Many thousands of new literature-database relationships are found by text mining, since these relationships are also not present in the set of articles cited by database records. We recommend that structured annotation of database records in articles is extended to other databases, such as ArrayExpress and Pfam, entries from which are also cited widely in the literature. The very high precision and high-throughput of this text-mining pipeline makes this activity possible both accurately and at low cost, which will allow the development of new integrated data services.

    Full Text Available Background: Scientific publications within Medical Sciences are an important factor for professionals to achieve services of excellence. However, the training to write this kind of articles is not enough. Objective: To design a theoretical and practical course of composition and style for scientific articles publications. Methods: Observational, descriptive, cross-sectional study including 50 professionals of the Medical School Branch. The main difficulties that they face to publish an article were determined and a distance learning course was designed on this basis, using the Moodle platform. Results: All the surveyed individuals referred that among the main causes limiting their ability to publish scientific articles are: little practical knowledge about the requirements to write scientific articles, not receiving any subject enhancing textual composition during their academic formation, and not attending to any post-graduate course aimed at improving academic writing for publication. A curse of 10 hours (theoretical part and 30 hours (practical part divide into five chapters including stylistic, methodological and compositional elements. Conclusions: This course helps improving the composition of scientific articles written by professional and their further publication in scientific journals.

    Full Text Available Problem statement: Stereotype threat has repeatedly been shown to depress women’s scores on difficult math tests. An attempt to replicate these findings in China found no support for the stereotype threat hypothesis. Our math test was characterized as being personally important for the student participants, an atypical condition in most stereotype threat laboratory research. Approach: To evaluate the effects of this personal demand, we conducted three experiments. Results: Experiment 1, where in Chinese students were tested with the added independent variable of test importance. Our results produced only marginally significant stereotype threat effects. Experiment 2, a replication of experiment 1, yielded completely different results, with no threat effects at all. Math-test scores were significantly higher in the threat condition for both men and women, consistent with the phenomena of stereotype lift and stereotype reactance. Experiment 3, which did not include the test-important variable, yielded no significant effects. Conclusion: Stereotype threat, in the mathematics domain, does not seem to be a problem for women in China. We discuss our results in terms of factors which moderate stereotype threat and societal differences in the U.S. and China.

    Total knee arthroplasties (TKAs) are reliable procedures for treating end-stage knee osteoarthritis with excellent long-term outcomes. The purpose of this study was to longitudinally evaluate temporal trends of Knee Society Scores (KSS) after TKA and to identify potential demographic and comorbid factors that affect these outcomes. This prospective study evaluated 281 patients (108 men and 173 women) with a mean age of 66 years (range, 39-80 years) who underwent primary TKA (minimum follow-up 5 years). During each follow-up visit, KS objective, function, and total scores were evaluated. The effects of different demographics and comorbidities on outcomes were further analyzed using multivariate regression analysis. Following TKA, peak mean KSS were observed at 1-year follow-up (mean, 92 points), after which there was no significant difference in scores at 5 years compared with 1-year follow-up (mean, 92 points). KS function scores were observed to be unchanged from preoperative levels (mean, 53 points) and at 6 weeks (mean, 56 points). These were significantly higher at 3 months (mean, 78 points) and reached a maximum mean peak at 1 year (mean, 85 points). KS objective scores increased earlier than function scores. The demographic variables and comorbidities that demonstrated a significantly negative impact in KS function scores were increased age, female gender, higher body mass index, and several medical comorbidities including immunological and neurological disease, and neoplasm. Race was the only variable that significantly decreased the KS objective scores. KSS after TKA follow temporal trends with scores initially unchanged from preoperative levels for the objective component, but the scores increased for the functional component. All components demonstrated higher levels compared with preoperative scores by 3 months and peaked at 1-year follow-up. At 5-year follow-up, all mean KSS were unchanged relative to peak scores seen at 1 year. Various patient

    According to the European Association of Urology (EAU) guidelines,a life expectancy of>10 years is considered an important factor in the treatment of prostate cancer.The Charlson score is used to predict mortality based on comorbidities.The purpose of this study was to investigate the relationship between age,Charlson score and outcome in patients with cT3a prostate cancer.Between 1987 and 2004,200 patients,who were with clinical T3a prostate cancer and who underwent radical prostatectomy (RP),were previously detected by digital rectal examination (DRE).Patients were categorized into two age groups (<65 and≥65 years old).Patients were also divided into two groups according to Charlson score (=0 and≥1).Both age and Charlson score were analyzed regarding their predictive power of patients' outcomes.The mean follow-up period was 70.6 months,and the mean age of patients was 63.3 years.In all,106 patients were<65 years old and 94 patients were≥65 years old.Age was a significant predictor of overall survival (OS).A Charlson score of O was found in 110 patients,and of≥1 in 90 patients.Charlson score was not a significant predictor of biochemical progression-free survival (BPFS),clinical progression-free survival (CPFS) or OS.Cox multivariate analysis showed that margin status was a significant independent factor in BPFS,and cancer volume was a significant independent factor in CPFS.Charlson score does not influence the outcome in patients with clinical locally advanced prostate cancer.Age may influence OS.RP can be performed in motivated healthy older patients.However,the patients need to be counseled regarding possible surgery-related side effects,such as urinary incontinence and erectile dysfunction,which are age-and comorbidity-dependent.

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

    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

    Full Text Available PURPOSE: The aim of this study was to evaluate the performance of strain elastography in an elasticity phantom and to assess which factors influenced visual scoring, strain histograms and strain ratios. Furthermore this study aimed to evaluate the effect of observer experience on visual scorings. MATERIALS AND METHODS: Two operators examined 20 targets of various stiffness and size (16.7 to 2.5 mm in an elasticity phantom at a depth of 3.5 cm with a 5-18 MHz transducer. Two pre-settings were used yielding 80 scans. Eight evaluators, four experienced, four inexperienced, performed visual scorings. Cut-offs for semi-quantitative methods were established for prediction of target stiffness. Data was pooled in two categories allowing calculations of sensitivity and specificity. Statistical tests chi-square test and linear regression as relevant. RESULTS: Strain ratios and strain histograms were superior to visual scorings of both experienced and inexperienced observers (p = 0.025, strain histograms vs. experienced observers, p<0.001, strain histograms vs. inexperienced observers, p = 0.044 strain ratios vs. experienced observers and p = 0.002 strain ratios vs. inexperienced observers. No significant difference in predicting target stiffness between strain ratios and strain histograms (p = 0.83 nor between experienced and inexperienced observers (p = 0.054 was shown when using four categories. When pooling data in two groups (80 kPa/45 kPa vs. 14/8 kPa the difference between the observers became significant (p<0.001. Target size had a significant influence on strain ratios measurements (p = 0.017 and on visual scorings (p<0.001 but not on the strain histograms(p = 0.358. Observer experience had significant effect on visual scorings(p = 0.003. CONCLUSION: Strain ratios and strain histograms are superior to visual scoring in assessing target stiffness in a phantom. Target size had a significant impact on strain ratios and

    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.

    2011-08-01

    Full Text Available Abstract Background Several instruments and clinical scoring systems have been established to evaluate patients with ligamentous knee injuries. A comparison of individual articles in the literature is challenging, not only because of heterogeneity in methodology, but also due to the variety of the scoring systems used to document clinical outcomes. There is limited information about the correlation between used scores and quality of life with no information being available on the impact of each score on the utility values. The aim of this study was to compare the most commonly used scores for evaluating patients with anterior cruciate ligament (ACL injuries, and to establish corresponding utility values. These values will be used for the interpretation and comparison of outcome results in the currently available literature for different treatment options. Methods Four hypothetical vignettes were defined, based on different levels of activities after rupture of the ACL to simulate typical situations seen in daily practice. A questionnaire, including the Health Utility Index (HUI for utility values, the IKDC subjective score, the Lysholm and the Tegner score, was created and 25 orthopedic surgeons were asked to fill the questionnaire for each hypothetical patient as proxies for all patients they had treated and who would fit in that hypothetical vignette. Results The utility value as an indicator for quality of life increased with the level of activity. Having discomforts already during normal activities of daily living was rated with a mean utility value of 0.37 ± 0.19, half of that of a situation where mild sport activity was possible without discomfort (0.78 ± 0.11. All investigated scores were able to distinguish clearly (p Conclusions Here we report the correlation between the most commonly used scores for the assessment of patients with a ruptured ACL and utility values as an indicator of quality of life.

    Ossification score and animal age are both used as proxies for maturity-related collagen crosslinking and consequently decreases in beef tenderness. Ossification score is strongly influenced by the hormonal status of the animal and may therefore better reflect physiological maturity and consequently eating quality. As part of a broader cross-European study, local consumers scored 18 different muscle types cooked in three ways from 482 carcasses with ages ranging from 590 to 6135 days and ossification scores ranging from 110 to 590. The data were studied across three different maturity ranges; the complete range of maturities, a lesser range and a more mature range. The lesser maturity group consisted of carcasses having either an ossification score of 200 or less or an age of 987 days or less with the remainder in the greater maturity group. The three different maturity ranges were analysed separately with a linear mixed effects model. Across all the data, and for the greater maturity group, animal age had a greater magnitude of effect on eating quality than ossification score. This is likely due to a loss of sensitivity in mature carcasses where ossification approached and even reached the maximum value. In contrast, age had no relationship with eating quality for the lesser maturity group, leaving ossification score as the more appropriate measure. Therefore ossification score is more appropriate for most commercial beef carcasses, however it is inadequate for carcasses with greater maturity such as cull cows. Both measures may therefore be required in models to predict eating quality over populations with a wide range in maturity. PMID:26687476

  4. Complex dynamics in the distribution of players’ scoring performance in Rugby Union world cups

    The evolution of the scoring performance of Rugby Union players is investigated over the seven rugby world cups (RWC) that took place from 1987 to 2011, and a specific attention is given to how they may have been impacted by the switch from amateurism to professionalism that occurred in 1995. The distribution of the points scored by individual players, Ps, ranked in order of performance were well described by the simplified canonical law Ps∝(, where r is the rank, and ϕ and α are the parameters of the distribution. The parameter α did not significantly change from 1987 to 2007 (α=0.92±0.03), indicating a negligible effect of professionalism on players’ scoring performance. In contrast, the parameter ϕ significantly increased from ϕ=1.32 for 1987 RWC, ϕ=2.30 for 1999 to 2003 RWC and ϕ=5.60 for 2007 RWC, suggesting a progressive decrease in the relative performance of the best players. Finally, the sharp decreases observed in both α(α=0.38) and ϕ(ϕ=0.70) in the 2011 RWC indicate a more even distribution of the performance of individuals among scorers, compared to the more heterogeneous distributions observed from 1987 to 2007, and suggest a sharp increase in the level of competition leading to an increase in the average quality of players and a decrease in the relative skills of the top players. Note that neither α nor ϕ significantly correlate with traditional performance indicators such as the number of points scored by the best players, the number of games played by the best players, the number of points scored by the team of the best players or the total number of points scored over each RWC. This indicates that the dynamics of the scoring performance of Rugby Union players is influenced by hidden processes hitherto inaccessible through standard performance metrics; this suggests that players’ scoring performance is connected to ubiquitous phenomena such as anomalous diffusion.

    Scientific research and the publication of the results of the studies go hand in hand. Exquisite research methods can only be adequately reflected in formal publication with the optimum structure. To ensure the success of this process, it is necessary to follow orderly steps, including selecting the journal in which to publish and following the instructions to authors strictly as well as the guidelines elaborated by diverse societies of editors and other institutions. It is also necessary to structure the contents of the article in a logical and attractive way and to use an accurate, clear, and concise style of language. Although not all the authors are directly involved in the actual writing, elaborating a scientific article is a collective undertaking that does not finish until the article is published. This article provides practical advice about formal and not-so-formal details to take into account when writing a scientific article as well as references that will help readers find more information in greater detail.

    Full Text Available Background Bipolar disorder (BD patients have been reported to be associated higher creativity abilities, and recent data tend to support the hypothesis that dopaminergic system that could be associated with creativity. Catechol-O-methyltransferase (COMT is one of the major enzymes involved in the metabolic degradation of dopamine. The COMT gene polymorphism (rs4680 or Val158Met Met allele is reported to cause decreased activity of this enzyme in prefrontal cortex and improve performance in several cognitive domains. Objective The objective of this study was to evaluate the influence of Val158Met on creativity in BD type I and healthy controls. Methods Ninety-seven healthy volunteers and 120 BD type I were genotyped for COMT rs4680 and tested for creativity (Barrow Welsh Art Scale – BWAS and intelligence Wechsler Abbreviated Scale of Intelligence (WASI. Results COMT Met allele positively influenced creativity scores in healthy controls but not in BD subjects during mood episodes and euthymia. The presence of allele Met did not influence IQ scores. No influence of IQ total score on creativity was observed. Limitations control group presented higher IQ scores and euthymic group was under medication use. Discussion Our research suggests positive effect of COMT rs4680 (allele Met on creativity scores in healthy controls. One possible interpretation is that creativity is more likely to be associated with lesser degrees of bipolarity. The fact that the same results were not observed in BD may be associated to dysfunctions in the dopaminergic system that characterizes this disorder. Further studies with larger samples and other types of BD should explore the role of the dopaminergic system in creativity.

    Full Text Available Abstract Background Patients referred to a medical admission unit (MAU represent a broad spectrum of disease severity. In the interest of allocating resources to those who might potentially benefit most from clinical interventions, several scoring systems have been proposed as a triaging tool. Even though most scoring systems are not meant to be used on an individual level, they can support the more inexperienced doctors and nurses in assessing the risk of deterioration of their patients. We therefore performed a systematic review on the level of evidence of literature on scoring systems developed or validated in the MAU. We hypothesized that existing scoring systems would have a low level of evidence and only few systems would have been externally validated. Methods We conducted a systematic search using Medline, EMBASE and the Cochrane Library, according to the PRISMA guidelines, on scoring systems developed to assess medical patients at admission. The primary endpoints were in-hospital mortality or transfer to the intensive care unit. Studies derived for only a single or few diagnoses were excluded. The ability to identify patients at risk (discriminatory power and agreement between observed and predicted outcome (calibration along with the method of derivation and validation (application on a new cohort were extracted. Results We identified 1,655 articles. Thirty were selected for further review and 10 were included in this review. Eight systems used vital signs as variables and two relied mostly on blood tests. Nine systems were derived using regression analysis and eight included patients admitted to a MAU. Six systems used in-hospital mortality as their primary endpoint. Discriminatory power was specified for eight of the scoring systems and was acceptable or better in five of these. The calibration was only specified for four scoring systems. In none of the studies impact analysis or inter-observer reliability were analyzed. None of the

    The use of simple linear mathematical models to estimate chemical properties is not a new idea. Albert Einstein used very simple 'gravity-like' forces to explain the capillarity of different liquids in 1900-1901. Today such models are used in more complicated situations, and a great many have been developed to analyse interactions between proteins and their ligands. This is not surprising, since proteins are too complicated to model accurately without lengthy numerical analysis, and simple models often do at least as good a job in predicting binding constants as much more computationally expensive methods. One hundred years after Einstein's 'miraculous year' in which he transformed physics, it is instructive to recall some of his even earlier work. As approximations, 'scoring functions' are excellent, but it is dangerous to read too much into them. A few cautionary tales are presented for the beginner to the field of ligand affinity prediction by linear models. PMID:16231202

  10. 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....

  14. Coronary artery calcium scoring in myocardial infarction

    International Nuclear Information System (INIS)

    Background. The aim of this study was to evaluate coronary artery calcium scoring and the assessment of the risk factors in patients with myocardial infarction (MI). Methods. During the period of three years, 27 patients with MI were analyzed. The average age of patients was 66.1 years (46 to 81). Coronary arteries calcium was evaluated by multi row detector computed tomography (MTDC) Somatom Volume Zoom Siemens, and, retrospectively by ECG gating data acquisition. Semi automated calcium quantification to calculate Agatston calcium score (CS) was performed with 4 x 2.5 mm collimation, using 130 ml of contrast medium, injected with an automatic injector, with the flow rate of 4 ml/sec. The delay time was determined empirically. At the same time several risk factors were evaluated. Results. Out of 27 patients with MI, 3 (11.1%) patients had low CS (10- 100), 5 (18.5%) moderate CS (101- 499), and 19 (70.4%) patients high CS (>500). Of risk factors, smoking was confirmed in 17 (63.0%), high blood pressure (HTA) in 10 (57.0%), diabetes mellitus in 7 (25.9%), positive family history in 5 (18.5%), pathological lipids in 5 (18.5%), alcohol abuse in 4 (1.8%) patients. Six (22.2%) patients had symptoms of angina pectoris. Conclusions. The research showed high correlation of MI and high CS (>500). Smoking, HTA, diabetes mellitus, positive family history and hypercholesterolemia are significant risk factors. Symptoms are relatively poor in large number of patients. (author)

    The treatment of keloids remains complex and challenging. A multitude of different treatment options exists. While current guidelines frequently promote the combination of intralesional triamcinolone acetonide (TAC) and cryotherapy as a first-line therapy for keloids, its efficacy has mainly been proven clinically and objective evaluation is widely missing. Here, we aimed to evaluate the efficacy of TAC and cryotherapy for the improvement of keloids by employing two well-recognized questionnaires for the evaluation of scar appearance and patient's quality of life. Twenty keloid patients from our outpatient scar clinic were treated with individual doses of TAC and cryotherapy in four consecutive sessions. Retrospectively, Patient and Observer Scar Assessment Scale (POSAS) and Dermatology Life Quality Index (DLQI) questionnaire data from those patients were analyzed to evaluate changes over five visits (one baseline, four after treatment). Both overall patient and observer scores of the POSAS significantly decreased (41.10 ± 9.771 to 29.85 ± 11.42 [p < 0.001] and 33.75 ± 6.231 to 22.70 ± 5.992 [p < 0.001], respectively), while DLQI scores significantly declined over the time period studied, indicating significant improvements in scar appearance. Objective evaluation confirmed the clinically demonstrated improvements of scar appearance and symptoms after treatments with TAC and cryotherapy which was associated with significant improvements in quality of life as indicated by DLQI measures. Standardized questionnaires help in objectifying clinical improvements; however, more detailed options for scar documentation, such as objective imaging, may be additionally required for an in-depth analysis of treatment progress.

  16. Characteristics and production of compound powder articles

    International Nuclear Information System (INIS)

    Characteristics of production of compound powder articles have been studied. It is shown that parts made from powder can be joined when heating using the 'growth' effect of pressed parts during sintering due to austenite-carbide alloy introduction into composition of the insent. Joining of parts is very strong if the structure of the jouning zone is similar to that of the basic material. It is reached by formation of grains common to joined materials due to the boundary migration induced either by primary or secondary recrystallization. The production parameters, temperature, sintering time, amount of the introduced addition, are ascertained to affect the joining strength. Properties of sintered materials based on iron are studied as affected by the process of complex thermodiffusion alloying. Mechanical properties, corrosion and scale resistance are determined in sintered articles with diffusion coatings. Saturation with chromium, nickel and silicon is shown to increase essentially mechanical-and-physical properties of sintered articles. (author)

The purpose of this trilogy of articles is to introduce shared services as a business model, and how to efficiently and effectively manage a shared services business unit. The purpose of the first article in the trilogy, introduces shared services as a business model, defines what shared services is, the transformation required to successfully implement a shared services business model, as well as the benefits that can be derived from implementing a shared services business model. Methodology: A comprehensive literature study was conducted in order to: - Define and describe shared services as a business model, - Compare shared services with centralisation and de-centralisation, - Determine and describe the transformation required to successfully implement shared services. Findings: In the article, a framework is generated to help organisations understand the business concept of shared services. This work has further potential: when applied correctly, there are both tangible and intangible benefits that can be accrued above cost savings. Implications: The findings of this article are important for organisations that are in the process of implementing or have implemented shared services, as it will assist the organisation in determining if shared services is the correct business model for them to implement. Value: This article provides an understanding of shared services and the business environment required to successfully implement a shared services business model. Value created by a shared services business model is further enhanced once the organisation has embarked on the successful implementation of a shared services business model, which is the primary objective of the second article, Implementation and continuous evolution in shared services.

  18. Passage-Based Bibliographic Coupling: An Inter-Article Similarity Measure for Biomedical Articles.

    Directory of Open Access Journals (Sweden)

    Rey-Long Liu

    Full Text Available Biomedical literature is an essential source of biomedical evidence. To translate the evidence for biomedicine study, researchers often need to carefully read multiple articles about specific biomedical issues. These articles thus need to be highly related to each other. They should share similar core contents, including research goals, methods, and findings. However, given an article r, it is challenging for search engines to retrieve highly related articles for r. In this paper, we present a technique PBC (Passage-based Bibliographic Coupling that estimates inter-article similarity by seamlessly integrating bibliographic coupling with the information collected from context passages around important out-link citations (references in each article. Empirical evaluation shows that PBC can significantly improve the retrieval of those articles that biomedical experts believe to be highly related to specific articles about gene-disease associations. PBC can thus be used to improve search engines in retrieving the highly related articles for any given article r, even when r is cited by very few (or even no articles. The contribution is essential for those researchers and text mining systems that aim at cross-validating the evidence about specific gene-disease associations.

  19. The Glasgow Prognostic Score, an inflammation based prognostic score, predicts survival in patients with hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Elevated Glasgow Prognostic Score (GPS) has been related to poor prognosis in patients with hepatocellular carcinoma (HCC) undergoing surgical resection or receiving sorafenib. The aim of this study was to investigate the prognostic value of GPS in patients with various stages of the disease and with different liver functional status. One hundred and fifty patients with newly diagnosed HCC were prospectively evaluated. Patients were divided according to their GPS scores. Univariate and multivariate analyses were performed to identify clinicopathological variables associated with overall survival; the identified variables were then compared with those of other validated staging systems. Elevated GPS were associated with increased asparate aminotransferase (P<0.0001), total bilirubin (P<0.0001), decreased albumin (P<0.0001), α-fetoprotein (P=0.008), larger tumor diameter (P=0.003), tumor number (P=0.041), vascular invasion (P=0.0002), extra hepatic metastasis (P=0.02), higher Child-Pugh scores (P<0.0001), and higher Cancer Liver Italian Program scores (P<0.0001). On multivariate analysis, the elevated GPS was independently associated with worse overall survival. Our results demonstrate that the GPS can serve as an independent marker of poor prognosis in patients with HCC in various stages of disease and different liver functional status

  1. Standard-setting methodology: Establishing performance standards and setting cut-scores to assist score interpretation.

    Zumbo, Bruno D

    2016-06-01

    A critical step in the development and use of tests of physical fitness for employment purposes (e.g., fitness for duty) is to establish 1 or more cut points, dividing the test score range into 2 or more ordered categories reflecting, for example, fail/pass decisions. Over the last 3 decades elaborated theories and methods have evolved focusing on the process of establishing 1 or more cut-scores on a test. This elaborated process is widely referred to as "standard-setting". As such, the validity of the test score interpretation hinges on the standard-setting, which embodies the purpose and rules according to which the test results are interpreted. The purpose of this paper is to provide an overview of standard-setting methodology. The essential features, key definitions and concepts, and various novel methods of informing standard-setting will be described. The focus is on foundational issues with an eye toward informing best practices with new methodology. Throughout, a case is made that in terms of best practices, establishing a test standard involves, in good part, setting a cut-score and can be conceptualized as evidence/data-based policy making that is essentially tied to test validity and an evidential trail.

    OpenAIRE

    Taisuke Otsu; Myung Hwan Seo

    2014-01-01

    Abstract. Since Manski's (1975) seminal work, the maximum score method for discrete choice models has been applied to various econometric problems. Kim and Pollard (1990) established the cube root asymptotics for the maximum score estimator. Since then, however, econometricians posed several open questions and conjectures in the course of generalizing the maximum score approach, such as (a) asymptotic distribution of the conditional maximum score estimator for a panel data dynamic discrete ch...

    Abstract Background Prognostic scores might be useful tools both in clinical practice and clinical trials, where they can be used as stratification parameter. The available scores for patients with brain metastases have never been tested specifically in patients with primary breast cancer. It is therefore unknown which score is most appropriate for these patients. Methods Five previously published prognostic scores were evaluated in a group of 83 patients with brain metastases from breast can...

  14. Environmental structure and competitive scoring advantages in team competitions

    OpenAIRE

    Sears Merritt; Aaron Clauset

    2013-01-01

    In most professional sports, the structure of the environment is kept neutral so that scoring imbalances may be attributed to differences in team skill. It thus remains unknown what impact structural heterogeneities can have on scoring dynamics and producing competitive advantages. Applying a generative model of scoring dynamics to roughly 10 million team competitions drawn from an online game, we quantify the relationship between a competition's structure and its scoring dynamics. Despite wi...

  15. Propensity score methodology for confounding control in health care utilization databases

    Directory of Open Access Journals (Sweden)

    Elisabetta Patorno

    2013-06-01

    Full Text Available Propensity score (PS methodology is a common approach to control for confounding in nonexperimental studies of treatment effects using health care utilization databases. This methodology offers researchers many advantages compared with conventional multivariate models: it directly focuses on the determinants of treatment choice, facilitating the understanding of the clinical decision-making process by the researcher; it allows for graphical comparisons of the distribution of propensity scores and truncation of subjects without overlapping PS indicating a lack of equipoise; it allows transparent assessment of the confounder balance achieved by the PS at baseline; and it offers a straightforward approach to reduce the dimensionality of sometimes large arrays of potential confounders in utilization databases, directly addressing the “curse of dimensionality” in the context of rare events. This article provides an overview of the use of propensity score methodology for pharmacoepidemiologic research with large health care utilization databases, covering recent discussions on covariate selection, the role of automated techniques for addressing unmeasurable confounding via proxies, strategies to maximize clinical equipoise at baseline, and the potential of machine-learning algorithms for optimized propensity score estimation. The appendix discusses the available software packages for PS methodology. Propensity scores are a frequently used and versatile tool for transparent and comprehensive adjustment of confounding in pharmacoepidemiology with large health care databases.

    2000-01-01

    An article is welded, as in weld repair of a defect, by positioning a weld lift-off block at a location on the surface of the article adjacent to the intended location of the end of the weldment on the surface of the article. The weld lift-off block has a wedge shape including a base contacting the surface of the article, and an upper face angled upwardly from the base from a base leading edge. A weld pool is formed on the surface of the article by directly heating the surface of the article using a heat source. The heat source is moved relative to the surface of the article and onto the upper surface of the weld lift-off block by crossing the leading edge of the wedge, without discontinuing the direct heating of the article by the heat source. The heating of the article with the heat source is discontinued only after the heat source is directly heating the upper face of the weld lift-off block, and not the article.

    Full Text Available Aim: To establish a scoring system for predicting the incidence of postoperative complications and mortality in patients with perforation peritonitis based on the modified physiological and operative severity score for the enumeration of mortality and morbidity (M-POSSUM, and to evaluate its efficacy. Methods: Patients under study, were grouped as those with postoperative complications (n = 35 and those without postoperative complications (n = 35. The period of study was 12 months and the data was analysed retrospectively and prospectively for logistical regression. Patients with age less than 12 years were excluded. Modified POSSUM (M-POSSUM was used and its efficacy evaluated. Fifteen indices were assessed as part of the scoring system such as age, cardiovascular function, respiratory function, blood test results, endocrine function, central nervous system function, hepatic function, renal function, nutritional status, extent of operative trauma, and course of anaesthesia. Results: Logistic regression analysis yielded statistically significant equations for both morbidity and mortality for comparison of both groups. The predictive accuracy of morbidity equation and mortality equation was 83.6% and 94.1%, respectively. Significant risk factors were found to be age, cardiovascular function, respiratory function, hepatic function, renal function, blood test results, endocrine function, nutritional status, duration of operation, intra-operative blood loss, and course of anaesthesia. These factors were all included in the scoring system. There was significant difference in the scores between the patients with and without postoperative complications, between the patients who died and those who survived with complications, and between the patients who died and those who survived without complications. Conclusion: Our study validates the main perioperative complications of surgery for perforation peritonitis and influencing and non-influencing risk

    2009-01-01

    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.

    Full Text Available Bankruptcy risk made the subject of many research studies that aim at identifying the time of the bankruptcy, the factors that compete to achieve this state, the indicators that best express this orientation (the bankruptcy. The threats to enterprises require the managers knowledge of continually economic and financial situations, and vulnerable areas with development potential. Managers need to identify and properly manage the threats that would prevent achieving the targets. In terms of methods known in the literature of assessment and evaluation of bankruptcy risk they are static, functional, strategic, and scoring nonfinancial models. This article addresses Altman and Conan-Holder-known internationally as the model developed at national level by two teachers from prestigious universities in our country-the Robu-Mironiuc model. Those models are applied to data released by the profit and loss account and balance sheet Turism Covasna company over which bankruptcy risk analysis is performed. The results of the analysis are interpreted while trying to formulate solutions to the economic and financial viability of the entity.

  2. Modification of Foamed Articles Based on Cassava Starch

    International Nuclear Information System (INIS)

    This work reports the influence of radiation, plasticizers and poly vinyl alcohol (PVA) on the barrier properties [water vapour permeability (WVP)) and mechanical properties (tensile strength and elongation; compression resistance and flexibility) of foamed articles based on cassava starch. The starch foam was obtained by thermopressing process. Poly ethylene glycol (PEG, 300) was selected as plasticizer and water was necessary for the preparation of the foams. The foamed articles based on cassava starch were irradiated at low doses of 2 and 5 kGy, commonly used in food irradiation. The mechanical properties of starch foams are influenced by the plasticizer concentration and by irradiation dose. An increase in PEG content showed a considerable increase in elongation percentage and a decrease in the tensile strength of the foams; also increase the permeability of the foams in water. After irradiation, the barrier properties and mechanical properties of the foams were improved due to chemical reactions among polymer molecules. Irradiated starch cassava foams with poly vinyl alcohol (PVA) have good flexibility and low water permeability. WVP can be reduced by low doses of gamma radiation

  3. Essays on probability elicitation scoring rules

    Firmino, Paulo Renato A.; dos Santos Neto, Ademir B.

    2012-10-01

    In probability elicitation exercises it has been usual to considerer scoring rules (SRs) to measure the performance of experts when inferring about a given unknown, Θ, for which the true value, θ*, is (or will shortly be) known to the experimenter. Mathematically, SRs quantify the discrepancy between f(θ) (the distribution reflecting the expert's uncertainty about Θ) and d(θ), a zero-one indicator function of the observation θ*. Thus, a remarkable characteristic of SRs is to contrast expert's beliefs with the observation θ*. The present work aims at extending SRs concepts and formulas for the cases where Θ is aleatory, highlighting advantages of goodness-of-fit and entropy-like measures. Conceptually, it is argued that besides of evaluating the personal performance of the expert, SRs may also play a role when comparing the elicitation processes adopted to obtain f(θ). Mathematically, it is proposed to replace d(θ) by g(θ), the distribution that model the randomness of Θ, and do also considerer goodness-of-fit and entropylike metrics, leading to SRs that measure the adherence of f(θ) to g(θ). The implications of this alternative perspective are discussed and illustrated by means of case studies based on the simulation of controlled experiments. The usefulness of the proposed approach for evaluating the performance of experts and elicitation processes is investigated.

  4. Gambling scores in earthquake prediction analysis

    CERN Document Server

    Molchan, G

    2010-01-01

    The number of successes 'n' and the normalized measure of space-time alarm 'tau' are commonly used to characterize the strength of an earthquake prediction method and the significance of prediction results. To evaluate better the forecaster's skill, it has been recently suggested to use a new characteristic, the gambling score R, which incorporates the difficulty of guessing each target event by using different weights for different alarms. We expand the class of R-characteristics and apply these to the analysis of results of the M8 prediction algorithm. We show that the level of significance 'alfa' strongly depends (1) on the choice of weighting alarm parameters, (2) on the partitioning of the entire alarm volume into component parts, and (3) on the accuracy of the spatial rate of target events, m(dg). These tools are at the disposal of the researcher and can affect the significance estimate in either direction. All the R-statistics discussed here corroborate that the prediction of 8.0<=M<8.5 events by...

  5. Fast network community detection by SCORE

    2012-01-01

    Consider a network where the nodes split into K different communities. The community labels for the nodes are unknown and it is of major interest to estimate them (i.e., community detection). Degree Corrected Block Model (DCBM) is a popular network model. How to detect communities with the DCBM is an interesting problem, where the main challenge lies in the degree heterogeneity. We propose a new approach to community detection which we call the Spectral Clustering On Ratios-of-Eigenvectors (SCORE). Compared to classical spectral methods, the main innovation is to use the entry-wise ratios between the first leading eigenvector and each of the other leading eigenvectors for clustering. The central surprise is, the effect of degree heterogeneity is largely ancillary, and can be effectively removed by taking entry-wise ratios between the leading eigenvectors. The method is successfully applied to the web blogs data and the karate club data, with error rates of 58/1222 and 1/34, respectively. These results are muc...

On the basis of literature metrology, comprehensive statistical methods such as quantitative analysis, the research gave suggestions on improving all of the earth science projects. [ Result/Conclusion] The results showed that: the funds has a promoting effect on all the National Natural Science Funds for Distinguished Young Scholar(NSFC-DYS) output, leads to the growth of all the NSFC-DYS to be a laboratory or large scientific team leader. There is no big difference in academic output between the female and male NSFC-DYSs, the maximum achievement can be expected when fund recipients are in their age of 37- 39. But as inflation and more and more of the same level funds as NSFC-DYS appeared in recent years, the fund’s academic output promoting effect on the recipient was decreasing year by year. The research suggested that less application constraints be imposed to promote the transition of the fund. The overall influence of the fund on academic output was on the rise except for the falls witnessed in certain years.

    2016-09-01

    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.

    Full Text Available Aim. Cognitive impairment in schizophrenia strongly relates to social outcome and is a good candidate for endophenotypes. When we accurately measure drug efficacy or effects of genes or variants relevant to schizophrenia on cognitive impairment, clinical factors that can affect scores on cognitive tests, such as age and severity of symptoms, should be considered. To elucidate the effect of clinical factors, we conducted multiple regression analysis using scores of the Continuous Performance Test Identical Pairs Version (CPT-IP, which is often used to measure attention/vigilance in schizophrenia. Methods. We conducted the CPT-IP (4-4 digit and examined clinical information (sex, age, education years, onset age, duration of illness, chlorpromazine-equivalent dose, and Positive and Negative Symptom Scale (PANSS scores in 126 schizophrenia patients in Japanese population. Multiple regression analysis was used to evaluate the effect of clinical factors. Results. Age, chlorpromazine-equivalent dose, and PANSS-negative symptom score were associated with mean d′ score in patients. These three clinical factors explained about 28% of the variance in mean d′ score. Conclusions. As conclusion, CPT-IP score in schizophrenia patients is influenced by age, chlorpromazine-equivalent dose and PANSS negative symptom score.

    The impact of important preexisting comorbidities, such as liver and renal disease, on the outcome of liver resection remains unclear. Identification of patients at risk of mortality will aid in improving preoperative preparations. The purpose of this study is to develop and validate a population-based score based on available preoperative and predictable parameters predicting 90-day mortality after liver resection using data from a hepatitis endemic country.We identified 13,159 patients who underwent liver resection between 2002 and 2006 in the Taiwan National Health Insurance Research Database. In a randomly selected half of the total patients, multivariate logistic regression analysis was used to develop a prediction score for estimating the risk of 90-day mortality by patient demographics, preoperative liver disease and comorbidities, indication for surgery, and procedure type. The score was validated with the remaining half of the patients.Overall 90-day mortality was 3.9%. Predictive characteristics included in the model were age, preexisting cirrhosis-related complications, ischemic heart disease, heart failure, cerebrovascular disease, renal disease, malignancy, and procedure type. Four risk groups were stratified by mortality scores of 1.1%, 2.2%, 7.7%, and 15%. Preexisting renal disease and cirrhosis-related complications were the strongest predictors. The score discriminated well in both the derivation and validation sets with c-statistics of 0.75 and 0.75, respectively.This population-based score could identify patients at risk of 90-day mortality before liver resection. Preexisting renal disease and cirrhosis-related complications had the strongest influence on mortality. This score enables preoperative risk stratification, decision-making, quality assessment, and counseling for individual patients. PMID:25211044

    Despite growing interest in quantifying and modeling the scoring dynamics within professional sports games, relative little is known about what patterns or principles, if any, cut across different sports. Using a comprehensive data set of scoring events in nearly a dozen consecutive seasons of college and professional (American) football, professional hockey, and professional basketball, we identify several common patterns in scoring dynamics. Across these sports, scoring tempo---when scoring events occur---closely follows a common Poisson process, with a sport-specific rate. Similarly, scoring balance---how often a team wins an event---follows a common Bernoulli process, with a parameter that effectively varies with the size of the lead. Combining these processes within a generative model of gameplay, we find they both reproduce the observed dynamics in all four sports and accurately predict game outcomes. These results demonstrate common dynamical patterns underlying within-game scoring dynamics across prof...

    Abstract The Gait Deviation Index (GDI) and Gait Profile Score (GPS) are the most used summary measures of gait in children with cerebral palsy (CP). However, the reliability and agreement of these indices have not been investigated, limiting their clinimetric quality for research and clinical...... practice. The aim of this study was to investigate the intra-rater reliability and agreement of summary measures of gait (GDI; GPS; and the Gait Variable Score (GVS) derived from the GPS). The intra-rater reliability and agreement were investigated across two repeated sessions in 18 children aged 5......–12 years diagnosed with spastic CP. No systematic bias was observed between the sessions and no heteroscedasticity was observed in Bland–Altman plots. For the GDI and GPS, excellent reliability with intraclass correlation coefficient (ICC) values of 0.8–0.9 was found, while the GVS was found to have fair...

    The Library of Babel, described by Jorge Luis Borges, stores an enormous amount of information. The Library exists ab aeterno. Wikipedia, a free online encyclopaedia, becomes a modern analogue of such a Library. Information retrieval and ranking of Wikipedia articles become the challenge of modern society. While PageRank highlights very well known nodes with many ingoing links, CheiRank highlights very communicative nodes with many outgoing links. In this way the ranking becomes two-dimensional. Using CheiRank and PageRank we analyze the properties of two-dimensional ranking of all Wikipedia English articles and show that it gives their reliable classification with rich and nontrivial features. Detailed studies are done for countries, universities, personalities, physicists, chess players, Dow-Jones companies and other categories.

    We describe a physical and logical layout analysis algorithm, which is applied to segment and label online medical journal articles (regular HTML and PDF-Converted-HTML files). For these articles, the geometric layout of the Web page is the most important cue for physical layout analysis. The key to physical layout analysis is then to render the HTML file in a Web browser, so that the visual information in zones (composed of one or a set of HTML DOM nodes), especially their relative position, can be utilized. The recursive X-Y cut algorithm is adopted to construct a hierarchical zone tree structure. In logical layout analysis, both geometric and linguistic features are used. The HTML documents are modeled by a Hidden Markov Model with 16 states, and the Viterbi algorithm is then used to find the optimal label sequence, concluding the logical layout analysis.

    Evaluation of text summarization approaches have been mostly based on metrics that measure similarities of system generated summaries with a set of human written gold-standard summaries. The most widely used metric in summarization evaluation has been the ROUGE family. ROUGE solely relies on lexical overlaps between the terms and phrases in the sentences; therefore, in cases of terminology variations and paraphrasing, ROUGE is not as effective. Scientific article summarization is one such cas...

    Full Text Available Abstract Background Medicare hospital Value-based purchasing (VBP program that links Medicare payments to quality of care will become effective from 2013. It is unclear whether specific hospital characteristics are associated with a hospital’s VBP score, and consequently incentive payments. The objective of the study was to assess the association of hospital characteristics with (i the mean VBP score, and (ii specific percentiles of the VBP score distribution. The secondary objective was to quantify the associations of hospital characteristics with the VBP score components: clinical process of care (CPC score and patient satisfaction score. Methods Observational analysis that used data from three sources: Medicare Hospital Compare Database, American Hospital Association 2010 Annual Survey and Medicare Impact File. The final study sample included 2,491 U.S. acute care hospitals eligible for the VBP program. The association of hospital characteristics with the mean VBP score and specific VBP score percentiles were assessed by ordinary least square (OLS regression and quantile regression (QR, respectively. Results VBP score had substantial variations, with mean score of 30 and 60 in the first and fourth quartiles of the VBP score distribution. For-profit status (vs. non-profit, smaller bed size (vs. 100–199 beds, East South Central region (vs. New England region and the report of specific CPC measures (discharge instructions, timely provision of antibiotics and beta blockers, and serum glucose controls in cardiac surgery patients were positively associated with mean VBP scores (p Conclusions Although hospitals serving the poor and the elderly are more likely to score lower under the VBP program, the correlation appears small. Profit status, geographic regions, number and type of CPC measures reported explain the most variation among scores.

    Objective: To investigate the distribution of academic conflicts, if any, in medical research articles. Methods: Twenty-seven and 25 medical research articles in the field of internal medicine were selected from English and Chinese respectable jour⁃nals, respectively. Then, the speech acts that reflected a conflict between a scientist’s knowledge claim and another scientist’s knowledge claim were manually searched and recorded in each paper. Data were analyzed using non-parametric Chi-test. Results:There were 123 academic conflicts recorded in the English corpus and 49 Academic Conflicts in the Chinese corpus. Significant difference was observed in the overall frequency of academic conflicts between the English and Chinese medical discourse (p=0.001). Besides, as for the distribution within research articles, introduction and discussion sections were the sections where Aca⁃demic Conflict speech acts were most likely to occur in both corpra. Conclusion: The Chinese scholars are less likely to criticize peers. Introduction and discussion sections were the sections where Academic Conflict speech acts were most likely to occur. Our results are in agreement with previous results and confirmed the claim that highly different cultures vary in their discourse prefer⁃ences. Our findings are of pedagogical significance.

    We present an article viewer application that allows a scientific reader to easily discover and share knowledge by linking genomics-related concepts to knowledge of disparate biomedical databases. High-throughput data streams generated by technical advancements have contributed to scientific knowledge discovery at an unprecedented rate. Biomedical Informaticists have created a diverse set of databases to store and retrieve the discovered knowledge. The diversity and abundance of such resources present biomedical researchers a challenge with knowledge discovery. These challenges highlight a need for a better informatics solution. We use a text mining algorithm, Genomine, to identify gene symbols from the text of a journal article. The identified symbols are supplemented with information from the GenoDB knowledgebase. Self-updating GenoDB contains information from NCBI Gene, Clinvar, Medgen, dbSNP, KEGG, PharmGKB, Uniprot, and Hugo Gene databases. The journal viewer is a web application accessible via a web browser. The features described herein are accessible on www.genotation.org The Genomine algorithm identifies gene symbols with an accuracy shown by .65 F-Score. GenoDB currently contains information regarding 59,905 gene symbols, 5633 drug-gene relationships, 5981 gene-disease relationships, and 713 pathways. This application provides scientific readers with actionable knowledge related to concepts of a manuscript. The reader will be able to save and share supplements to be visualized in a graphical manner. This provides convenient access to details of complex biological phenomena, enabling biomedical researchers to generate novel hypothesis to further our knowledge in human health.

    Full Text Available The semantics of the articles is crucial for their proper usage in L2 speakers. However, we believe that for their proper acquisition a pairing of concrete form and concrete meaning must take place. In other words, a schema must be created for various meanings of articles. Therefore, in this paper English articles will be viewed from the aspect of Construction grammar. Working within the framework of CxG we will perceive the noun phrases of the type a/the+ N as lexico-syntactic meaningful constructions where the articles attribute a particular meaning to the noun(s they determine. Together they constitute Determination (article Construction. Each particular meaning of the articles can be conceptualized and adequate abstract constructional schemas and subschemas as a schematic pairing of form and meaning can be created. In addition, we will use the Serbo-Croatian semantic equivalents of English articles such as indefinite pronouns neki, poneki, koji, kakav, numerals jedan, ijedan, adverbs nekako and makar, demonstrative determiners onaj, adjectives, negative forms ni, nikakav, possessive pronominals and many more. They will serve as a starting point for offering possible constructional schema models for meaningful constructions a/the +N. Other meanings and usages of the articles will be treated in the same way.

    Within medical applications there are two main types of information design; paper-based and digital information [1]. As technology is constantly changing, information within healthcare management and delivery is continually being transitioned from traditional paper documents to digital and online resources. Activity of Daily Living (ADL) charts are still predominantly paper based and are therefore prone to "human error" [2]. In light of this, an investigation has taken place into the design for reducing the amount of human error, between a paper based ADL, specifically the Barthel Index, and the same ADL created digitally. The digital ADL was developed as an online platform as this offers the best method of data capture for a large group of participants all together [3]. The aim of the study was to evaluate the usability of the Barthel Index ADL in paper format and then reproduce the same ADL digitally. This paper presents the findings of a study involving 26 participants who were familiar with ADL charts, and used three scenarios requiring them to complete both a paper ADL and a digital ADL. An evaluation was undertaken to ascertain if there were any 'human errors' in completing the paper ADL and also to find similarities/differences through using the digital ADL. The results from the study indicated that 22/26 participants agreed that the digital ADL was better, if not the same as a paper based ADL. Further results indicated that participants rate highly the added benefit of the digital ADL being easy to use and also that calculation of assessment scores were performed automatically. Statistically the digital BI offered a 100 % correction rate in the total calculation, in comparison to the paper based BI where it is more common for users to make mathematical calculation errors. Therefore in order to minimise handwriting and calculation errors, the digital BI proved superior than the traditional paper based method. PMID:26250757

  13. Gambling score in earthquake prediction analysis

    2011-03-01

    The number of successes and the space-time alarm rate are commonly used to characterize the strength of an earthquake prediction method and the significance of prediction results. It has been recently suggested to use a new characteristic to evaluate the forecaster's skill, the gambling score (GS), which incorporates the difficulty of guessing each target event by using different weights for different alarms. We expand parametrization of the GS and use the M8 prediction algorithm to illustrate difficulties of the new approach in the analysis of the prediction significance. We show that the level of significance strongly depends (1) on the choice of alarm weights, (2) on the partitioning of the entire alarm volume into component parts and (3) on the accuracy of the spatial rate measure of target events. These tools are at the disposal of the researcher and can affect the significance estimate. Formally, all reasonable GSs discussed here corroborate that the M8 method is non-trivial in the prediction of 8.0 ≤M < 8.5 events because the point estimates of the significance are in the range 0.5-5 per cent. However, the conservative estimate 3.7 per cent based on the number of successes seems preferable owing to two circumstances: (1) it is based on relative values of the spatial rate and hence is more stable and (2) the statistic of successes enables us to construct analytically an upper estimate of the significance taking into account the uncertainty of the spatial rate measure.

    Full Text Available Numerous studies have demonstrated a relationship between Mediterranean Diet (MD adherence and the prevention of cardiovascular diseases, cancer, and diabetes, etc. The study aim was to validate a novel instrument to measure MD adherence based on the consumption of food servings and food groups, and apply it in a female population from southern Spain and determining influential factors.The study included 1,155 women aged 12-83 yrs, classified as adolescents, adults, and over-60-yr-olds. All completed a validated semi-quantitative food frequency questionnaire (FFQ. The Mediterranean Dietary Serving Score (MDSS is based on the latest update of the Mediterranean Diet Pyramid, using the recommended consumption frequency of foods and food groups; the MDSS ranges from 0 to 24. The discriminative power or correct subject classification capacity of the MDSS was analyzed with the Receiver Operating Characteristic (ROC curve, using the MDS as reference method. Predictive factors for higher MDSS adherence were determined with a logistic regression model, adjusting for age. According to ROC curve analysis, MDSS evidenced a significant discriminative capacity between adherents and non-adherents to the MD pattern (optimal cutoff point=13.50; sensitivity=74%; specificity=48%. The mean MDSS was 12.45 (2.69 and was significantly higher with older age (p<0.001. Logistic regression analysis showed highest MD adherence by over 60-year-olds with low BMI and no habit of eating between meals.The MDSS is an updated, easy, valid, and accurate instrument to assess MD adherence based on the consumption of foods and food groups per meal, day, and week. It may be useful in future nutritional education programs to prevent the early onset of chronic non-transmittable diseases in younger populations.

Campion and Matthew H. Reider were originally incorrect. All versions of this article have been corrected.] Emerging advancements including the exponentially growing availability of computer-collected data and increasingly sophisticated statistical software have led to a "Big Data Movement" wherein organizations have begun attempting to use large-scale data analysis to improve their effectiveness. Yet, little is known regarding how organizations can leverage these advancements to develop more effective personnel selection procedures, especially when the data are unstructured (text-based). Drawing on literature on natural language processing, we critically examine the possibility of leveraging advances in text mining and predictive modeling computer software programs as a surrogate for human raters in a selection context. We explain how to "train" a computer program to emulate a human rater when scoring accomplishment records. We then examine the reliability of the computer's scores, provide preliminary evidence of their construct validity, demonstrate that this practice does not produce scores that disadvantage minority groups, illustrate the positive financial impact of adopting this practice in an organization (N ∼ 46,000 candidates), and discuss implementation issues. Finally, we discuss the potential implications of using computer scoring to address the adverse impact-validity dilemma. We suggest that it may provide a cost-effective means of using predictors that have comparable validity but have previously been too expensive for large-scale screening.

    Accurate neuropsychological assessment of older individuals from heterogeneous backgrounds is a major challenge. Education, ethnicity, language, and age are associated with scale level differences in test scores, but item level bias might contribute to these differences. We evaluated several strategies for dealing with item and scale level demographic influences on a measure of executive abilities defined by working memory and fluency tasks. We determined the impact of differential item funct...

    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

    A single-electron tunneling (SET) device with a nanoscale central island that can move with respect to the bulk source- and drain electrodes allows for a nanoelectromechanical (NEM) coupling between the electrical current through the device and mechanical vibrations of the island. Although an electromechanical "shuttle" instability and the associated phenomenon of single-electron shuttling were predicted more than 15 years ago, both theoretical and experimental studies of NEM-SET structures are still carried out. New functionalities based on quantum coherence, Coulomb correlations and coherent electron-spin dynamics are of particular current interest. In this article we present a short review of recent activities in this area.

    In the medical sciences, the importance of review articles is rising. When clinicians want to update their knowledge and generate guidelines about a topic, they frequently use reviews as a starting point. The value of a review is associated with what has been done, what has been found and how these findings are presented. Before asking ‘how,’ the question of ‘why’ is more important when starting to write a review. The main and fundamental purpose of writing a review is to create a readable sy...

    2009-01-01

    Full Text Available An Optical Music Recognition (OMR system especially adapted for handwritten musical scores of the XVII-th and the early XVIII-th centuries written in white mensural notation is presented. The system performs a complete sequence of analysis stages: the input is the RGB image of the score to be analyzed and, after a preprocessing that returns a black and white image with corrected rotation, the staves are processed to return a score without staff lines; then, a music symbol processing stage isolates the music symbols contained in the score and, finally, the classification process starts to obtain the transcription in a suitable electronic format so that it can be stored or played. This work will help to preserve our cultural heritage keeping the musical information of the scores in a digital format that also gives the possibility to perform and distribute the original music contained in those scores.

    MANAGING MISSING SCORES ON THE ROLAND MORRIS DISABILITY QUESTIONNAIRE  Peter Kenta and Henrik Hein Lauridsenb  aBack Research Centre and bInstitute of Sports Science and Clinical Biomechanics, University of Southern Denmark Background There is no standard method to calculate Roland Morris...... Disability Questionnaire (RMDQ) sum scores when one or more questions have not been answered. However, missing data are common on the RMDQ and the current options are: calculate a sum score regardless of unanswered questions, reject all data containing unanswered questions, or to impute scores. Other...... questionnaires, such as the Oswestry Disability Index (Oswestry) convert their raw score into a standardized score out of 100. An advantage of this method is that it allows missing data to be accommodated by proportional recalculation. For example, if 17 questions had been answered ’yes’ on a RMDQ questionnaire...

  13. TRII: A Probabilistic Scoring of Drosophila melanogaster Translation Initiation Sites

    Directory of Open Access Journals (Sweden)

    Rice Michael D

    2010-01-01

    Full Text Available Relative individual information is a measurement that scores the quality of DNA- and RNA-binding sites for biological machines. The development of analytical approaches to increase the power of this scoring method will improve its utility in evaluating the functions of motifs. In this study, the scoring method was applied to potential translation initiation sites in Drosophila to compute Translation Relative Individual Information (TRII scores. The weight matrix at the core of the scoring method was optimized based on high-confidence translation initiation sites identified by using a progressive partitioning approach. Comparing the distributions of TRII scores for sites of interest with those for high-confidence translation initiation sites and random sequences provides a new methodology for assessing the quality of translation initiation sites. The optimized weight matrices can also be used to describe the consensus at translation initiation sites, providing a quantitative measure of preferred and avoided nucleotides at each position.

    This article focuses on the implementation of propensity score matching for clustered data. Different approaches to reduce bias due to cluster-level confounders are considered and compared using Monte Carlo simulations. We investigated methods that exploit the clustered structure of the data in two ways: in the estimation of the propensity score model (through the inclusion of fixed or random effects) or in the implementation of the matching algorithm. In addition to a pure within-cluster matching, we also assessed the performance of a new approach, 'preferential' within-cluster matching. This approach first searches for control units to be matched to treated units within the same cluster. If matching is not possible within-cluster, then the algorithm searches in other clusters. All considered approaches successfully reduced the bias due to the omission of a cluster-level confounder. The preferential within-cluster matching approach, combining the advantages of within-cluster and between-cluster matching, showed a relatively good performance both in the presence of big and small clusters, and it was often the best method. An important advantage of this approach is that it reduces the number of unmatched units as compared with a pure within-cluster matching. We applied these methods to the estimation of the effect of caesarean section on the Apgar score using birth register data. Copyright © 2016 John Wiley & Sons, Ltd. PMID:26833893

  15. Bone mineralization in male commercial broilers and its relationship to gait score.

    Broilers selected for increased body size and breast muscle have imposed stress on the skeletal system, resulting in poorer walking ability. Our objectives were to determine the relationship between bone mineralization and gait score in 4 crosses of commercial broilers and to ascertain if mineralization of the toe is correlated to the tibia. Three chickens per pen each with good (gait score of 0 or 1) or poorer (gait score of 3) walking ability were killed and weighed. The left humerus, the left middle toe, and both drumsticks were collected for determination of bone mineral density (BMD), bone mineral content, and bone size traits using dual-energy x-ray absorptiometry. The BMD and bone size traits were similar among the 4 crosses of commercial broilers at 6 wk of age. However, gait scores differed among genotypes, with cross C having better gait scores than crosses A and B, but did not differ from cross D. The bone mineral content and bone size traits did not differ between birds with good walking ability as compared with those broilers of poorer walking ability. However, birds with poorer walking ability had higher BMD (P<0.05) and BW (P<0.001) than males with good walking ability. Within a cross, the correlation between gait score and BMD was not significant except for cross D birds. Broilers of cross D with better walking ability had decreased bone mineralization (r=0.19, P=0.03). The stronger correlation between gait score and BW for all crosses of commercial broilers (r=0.38, P<0.0001) suggests that the low association between gait score and bone mineralization for cross D was mainly due to BW. The BMD of the left toe was correlated to the BMD of the left tibia (r=0.91, P<0.0001) and right tibia (r=0.87, P<0.0001). In conclusion, bone mineralization was similar among crosses of meat-type chickens, and it had little influence on the gait score of male broilers. PMID:20075288

    We propose a generalization of the wild bootstrap of Wu (1986) and Liu (1988) based upon perturbing the scores of M-estimators. This "score bootstrap" procedure avoids recomputing the estimator in each bootstrap iteration, making it substantially less costly to compute than the conventional nonparametric bootstrap, particularly in complex nonlinear models. Despite this computational advantage, in the linear model, the score bootstrap studentized test statistic is equivalent to that of the con...
