    The objective of this study was to present the computerized structure that enables the use of the Nursing Activities Score (NAS) in mobile technology. It is a project for the development of technology production based on software engineering, founded on the theory of systems development life cycle. The NAS system was built in two modules: the search module, which is accessed using a personal computer (PC), and Data Collection module, which is accessed through a mobile device (Smartphone). The NAS system was constructed to allow other forms, in addition to the NAS tool, to be included in the future. Thus, it is understood that the development of the NAS will bring nurses closer to mobile technology and facilitate their accessibility to the data of the instrument relating to patients, thus assisting in decision-making and in staffing to provide nursing care.

    2013-01-01

    Performing music on the basis of reading a score requires reading ahead of what is being played in order to anticipate the necessary actions to produce the notes. Score reading thus not only involves the decoding of a visual score and the comparison to the auditory feedback, but also short-term storage of the musical information due to the delay of the auditory feedback during reading ahead. This study investigates the mechanisms of encoding of musical information in short-term memory during ...

  9. Why mental arithmetic counts: brain activation during single digit arithmetic predicts high school math scores.

    Price, Gavin R; Mazzocco, Michèle M M; Ansari, Daniel

    2013-01-01

    Do individual differences in the brain mechanisms for arithmetic underlie variability in high school mathematical competence? Using functional magnetic resonance imaging, we correlated brain responses to single digit calculation with standard scores on the Preliminary Scholastic Aptitude Test (PSAT) math subtest in high school seniors. PSAT math scores, while controlling for PSAT Critical Reading scores, correlated positively with calculation activation in the left supramarginal gyrus and bilateral anterior cingulate cortex, brain regions known to be engaged during arithmetic fact retrieval. At the same time, greater activation in the right intraparietal sulcus during calculation, a region established to be involved in numerical quantity processing, was related to lower PSAT math scores. These data reveal that the relative engagement of brain mechanisms associated with procedural versus memory-based calculation of single-digit arithmetic problems is related to high school level mathematical competence, highlighting the fundamental role that mental arithmetic fluency plays in the acquisition of higher-level mathematical competence.

  11. Schizotypal perceptual aberrations of time: correlation between score, behavior and brain activity.

    Shahar Arzy

    Full Text Available A fundamental trait of the human self is its continuum experience of space and time. Perceptual aberrations of this spatial and temporal continuity is a major characteristic of schizophrenia spectrum disturbances--including schizophrenia, schizotypal personality disorder and schizotypy. We have previously found the classical Perceptual Aberration Scale (PAS scores, related to body and space, to be positively correlated with both behavior and temporo-parietal activation in healthy participants performing a task involving self-projection in space. However, not much is known about the relationship between temporal perceptual aberration, behavior and brain activity. To this aim, we composed a temporal Perceptual Aberration Scale (tPAS similar to the traditional PAS. Testing on 170 participants suggested similar performance for PAS and tPAS. We then correlated tPAS and PAS scores to participants' performance and neural activity in a task of self-projection in time. tPAS scores correlated positively with reaction times across task conditions, as did PAS scores. Evoked potential mapping and electrical neuroimaging showed self-projection in time to recruit a network of brain regions at the left anterior temporal cortex, right temporo-parietal junction, and occipito-temporal cortex, and duration of activation in this network positively correlated with tPAS and PAS scores. These data demonstrate that schizotypal perceptual aberrations of both time and space, as reflected by tPAS and PAS scores, are positively correlated with performance and brain activation during self-projection in time in healthy individuals along the schizophrenia spectrum.

  16. Reliability of Accelerometer Scores for Measuring Sedentary and Physical Activity Behaviors in Persons With Multiple Sclerosis.

    Klaren, Rachel E; Hubbard, Elizabeth A; Zhu, Weimo; Motl, Robert W

    2016-04-01

    This brief research note examined the reliability of scores from an accelerometer as measures of sedentary and physical activity behaviors in persons with multiple sclerosis (MS). The analysis was performed on a combined data set from 2 previous longitudinal investigations of physical activity in MS. We focused on the number of days required to reliably estimate sedentary behavior, based on time spent in sedentary behavior per day and number of sedentary breaks, number of long sedentary bouts, and average length of sedentary bouts per day. We further examined the number of days required to reliably estimate physical activity behavior, based on time spent in light and moderate-to-vigorous physical activity and average length of activity bouts per day. Between 4-6 days of monitoring and 3-7 days of monitoring were necessary for good reliability of scores from all sedentary outcomes and physical activity outcomes, respectively. These results should guide research and practice examining sedentary and physical activity behaviors using accelerometry in persons with MS. PMID:27078272

    2015-09-01

    Full Text Available Introduction: Physical activity has become an important intervention against overweight and obesity cases in the USA and worldwide. One key aspect of physical activity is walking, which has been identified as a component that can easily be incorporated into one’s lifestyle. Recent studies on physical activity have focused on promoting walking as a health enhancing endeavor. In 2010, the proportion of Texas adults who reported no participation in leisure time activity (26.7% was significantly higher than the national average (24.4%. However, many Texans, like most Americans, are sedentary. Purpose: This study examined the walkability of the environments in selected counties in east Texas including Wood, Van Zandt and Smith counties. Methods and material: The data was drawn from the Walkscore.com and was based on all the zip codes in the three counties in east Texas. The community capitals were used a framework for analysis.  Results: Only three (8.82% zip codes had walkable scores between 70 and 89; five (14.71% had scores between 50 and 69; four (11.76% between 25 and 49 and 22 (64.71% had a score below 24. Discussion: The vast majority (26, 76.47% of zip codes are highly dependent on vehicle transport. Conclusions and recommendations: Stakeholders need therefore to focus on causes for the minimal walkability so that practical interventions are generated to enhance the physical activity friendly infrastructure so as to enhance the well-being of the residents in these three east Texas counties.

    Several multi-item activities of daily living (ADL) scales have been developed for assessment of functional status of patients with Alzheimer’s Disease (AD) in the last few decades. A disadvantage of the large number of scales is that scores of different ADL scales cannot be compared directly with each other. ADL scales which are used by McNamee’s (Townsend's disability scale) and Hill’s (Medicare Beneficiary definitions and Katz index of ADL) provide suitable tools for modelling the cost-eff...

  2. Disease activity score in rheumatoid arthritis with or without secondary fibromyalgia

    Objective: To correlate disease activity score (DAS-28) in the patients with rheumatoid arthritis (RA) with and without secondary fibromyalgia. Study Design: Comparative cross-sectional study. Place and Duration of Study: Department of Rheumatology, Pakistan Institute of Medical Sciences, Islamabad, from November 2011 to April 2012. Methodology: Patients aged above 16 years diagnosed to have rheumatoid arthritis according to ACR/EULAR criteria 2010 were included in the study. Fibromyalgia (FM) was diagnosed by ACR 1990 criteria. Patients of other autoimmune diseases or psychiatric illnesses were excluded. DAS was determined and compared using t-test with significance at p < 0.05. Results: The mean age of study subjects was 42.9 years. Thirty one out of total 138 patients had fibromyalgia (22.4%). Female gender was predominant (92.0%); being 96.8% in patients with and in 88.2% without fibromyalgia. The average DAS score was high (5.3 + 1.5) in fibromyalgia patients compared to those without fibromyalgia (3.9 + 1.2); this difference in mean value was statistically significant (p = < 0.001). Conclusion: DAS-28 is a useful tool for assessing rheumatoid arthritis disease status in outpatient setting, however, increased disease activity must be assessed for possible co-existence of fibromyalgia which can spuriously give high DAS value and adversely affect treatment decision.

    Metabolic syndrome is a complex disorder represented by a set of cardiovascular risk factors. A healthy lifestyle is strongly related to improve Quality of Life and interfere positively in the control of risk factors presented in this condition. To evaluate the effect of a program of lifestyle modification on the Framingham General Cardiovascular Risk Profile in subjects diagnosed with metabolic syndrome. A sub-analysis study of a randomized clinical trial controlled blind that lasted three months. Participants were randomized into four groups: dietary intervention + placebo (DIP), dietary intervention + supplementation of omega 3 (fish oil 3 g/day) (DIS3), dietary intervention + placebo + physical activity (DIPE) and dietary intervention + physical activity + supplementation of omega 3 (DIS3PE). The general cardiovascular risk profile of each individual was calculated before and after the intervention. The study included 70 subjects. Evaluating the score between the pre and post intervention yielded a significant value (p < 0.001). We obtained a reduction for intermediate risk in 25.7% of subjects. After intervention, there was a significant reduction (p < 0.01) on cardiovascular age, this being more significant in groups DIP (5.2%) and DIPE (5.3%). Proposed interventions produced beneficial effects for reducing cardiovascular risk score. This study emphasizes the importance of lifestyle modification in the prevention and treatment of cardiovascular diseases.

  7. Evaluation of Crohn's disease activity: Initial validation of a magnetic resonance enterography global score (MEGS) against faecal calprotectin

    To develop an MRI enterography global score (MEGS) of Crohn's disease (CD) activity compared with a reference standard of faecal calprotectin (fC), C-reactive protein (CRP) and Harvey-Bradshaw index (HBI). Calprotectin, CRP and HBI were prospectively recorded for 71 patients (median age 33, male 35) with known/suspected CD undergoing MRI enterography. Two observers in consensus scored activity for nine bowel segments, grading mural thickness, T2 signal, mesenteric oedema, T1 enhancement and pattern, and haustral loss. Segmental scores were multiplied according to disease length. Five points each were added for lymphadenopathy, comb sign, fistulae and abscesses to derive the MEGS. A previously validated MRI CD activity score (CDAS) was also calculated. MRI scores were correlated with clinical references using Spearman's rank. A logistic regression diagnostic model was built to discriminate active (fC > 100 μg/g) from inactive disease. MEGS and CDAS were significantly correlated with fC (r = 0.46, P < 0.001) and (r = 0.39, P = 0.001) respectively. MEGS correlated with CRP (r = 0.39, P = 0.002). The model for discriminating active from inactive disease achieved an area under the receiver-operating curve of 0.75 and 0.66 after leave-one-out analysis. A magnetic resonance enterography global score (MEGS) of CD activity correlated significantly with fC levels. (orig.)

    Full Text Available Estudou-se a aplicação do conceito de "risco" na área materno-infantil, partindo da proposta da Organização Mundial de Saúde relativa ao "enfoque de risco" na organização dos serviços de saúde. O estudo concentrou-se no desenvolvimento de instrumentos de identificação de grupos de alto risco de óbito infantil, seja no período neonatal, seja no período pós-neonatal, e baseou-se em estudo de caso-controle. O grupo de casos correspondeu a óbitos registrados de menores de um ano de idade, ocorridos nos anos de 1984 e 1985, de pais residentes nos municípios de Cotia e Vargem Grande Paulista, SP (Brasil, totalizando 149 óbitos (casos. O grupo controle foi formado por uma amostra probabilística de 216 crianças nascidas em 1984, filhas de pais residentes nos municípios estudados e que sobreviveram ao primeiro ano de vida, As mães de ambos os grupos responderam a um questionário, aplicado em entrevistas domiciliarias, para a identificação de variáveis independentes associadas ao óbito infantil. As variáveis que mostraram associação estatisticamente significante foram agrupadas em quatro escalas de risco: para uso em pré-natal; para uso por ocasião do parto; para uso no período neonatal; e para uso em puericultura após o período neonatal. As variáveis participaram nas escalas ponderadas pelos valores das razões dos produtos cruzados. As escalas apresentaram diferentes pontos de corte e a cada um destes correspondeu uma dada sensibilidade, especificidade e poder preditivo.The application of the concept of "risk" to maternal and child health was studied, the starting point being the World Health Organization's proposal for a "risk approach" in health services.

    Conclusion The circulating IL-18 and IL-10 concentrations were significantly elevated in SLE patients and correlated with the SLEDAI score. The study emphasized that there exists an upregulated proinflammatory as well as anti-inflammatory responses in patients with active SLE; however, the anti-inflammatory response is not enough to suppress the active disease. Identifying the exact contribution of the currently studied cytokines might provide future insights for targeted therapeutic strategies in SLE.

    Full Text Available Indirect immunofluorescence (IIF has been used to identify and measure autoantibody levels in pemphigus vulgaris but data about relationship between clinical severity of disease and antibody titers by IIF have been conflicting. We conducted this cross-sectional study to correlate the severity of oral and/or cutaneous involvement in patients with pemphigus vulgaris based on Pemphigus Area and Activity Score with IIF titers. Sixty-one new pemphigus vulgaris patients were included in this study. Human prepuce was used as substrate for IIF and assessment of disease severity was based on Pemphigus Area and Activity Score. The mean±SD age was 44.04±30.46 years, with a range of 18 to 79 years. IIF was positive in 56 (91.8% patients. There was a significant relationship between total disease score and IIF titers ((P<0.001. Also a significant relationship was found between skin score (P=0.04 and mucosal score (P=0.04 with IIF titers. Our results show that there is a significant relationship between disease activity based on Pemphigus Area and Activity Score and antibody titers by IIF. Further studies are recommended to determine the usefulness of this technique for monitoring disease.

    Full Text Available Background. Prostate cancer is the most common noncutaneous cancer and second leading cause of cancer-related mortality in men in the US. Growing evidence suggests that oxidative stress is involved in prostate cancer. Methods. In this study, thioredoxin 1 (Trx 1, an enzyme and subcellular indicator of redox status, was measured in prostate biopsy tissue from 55 men from the North Carolina-Louisiana Prostate Cancer Project. A pathologist blindly scored levels of Trx 1. The association between Trx 1 and the Gleason score, erythrocyte antioxidant enzyme activity, and dietary antioxidant intake was determined using Fisher’s exact test. Results. Trx 1 levels in benign prostate tissue in men with incident prostate cancer were positively associated with the Gleason score (P=0.01 and inversely associated with dietary antioxidant intake (P=0.03. In prostate cancer tissue, Trx 1 levels were associated with erythrocyte glutathione peroxidase activity (P=0.01. No association was found for other erythrocyte enzymes. Greater Gleason score of malignant tissue corresponds to a greater difference in Trx 1 levels between malignant and benign tissue (P=0.04. Conclusion. These results suggest that the redox status of prostate tissue is associated with prostate cancer grade and both endogenous and exogenous antioxidants.

    Pathologists provide diagnoses relevant to the disease state of the patient and identify specific tissue characteristics relevant to response to therapy and prognosis. As personalized medicine evolves, there is a trend for increased demand of tissue-derived parameters. Pathologists perform increasingly complex analyses on the same 'cases'. Traditional methods of workload assessment and reimbursement, based on number of cases sometimes with a modifier (eg, the relative value unit (RVU) system used in the United States), often grossly underestimate the amount of work needed for complex cases and may overvalue simple, small biopsy cases. We describe a new approach to pathologist workload measurement that aligns with this new practice paradigm. Our multisite institution with geographically diverse partner institutions has developed the Automatable Activity-Based Approach to Complexity Unit Scoring (AABACUS) model that captures pathologists' clinical activities from parameters documented in departmental laboratory information systems (LISs). The model's algorithm includes: 'capture', 'export', 'identify', 'count', 'score', 'attribute', 'filter', and 'assess filtered results'. Captured data include specimen acquisition, handling, analysis, and reporting activities. Activities were counted and complexity units (CUs) generated using a complexity factor for each activity. CUs were compared between institutions, practice groups, and practice types and evaluated over a 5-year period (2008-2012). The annual load of a clinical service pathologist, irrespective of subspecialty, was ∼40,000 CUs using relative benchmarking. The model detected changing practice patterns and was appropriate for monitoring clinical workload for anatomical pathology, neuropathology, and hematopathology in academic and community settings, and encompassing subspecialty and generalist practices. AABACUS is objective, can be integrated with an LIS and automated, is reproducible, backwards compatible

    The investigation of the complex processes involved in cellular differentiation must be based on unbiased, high throughput data processing methods to identify relevant biological pathways. A number of bioinformatics tools are available that can generate lists of pathways ranked by statistical significance (i.e. by p-value), while ideally it would be desirable to functionally score the pathways relative to each other or to other interacting parts of the system or process. We describe a new computational method (Network Activity Score Finder - NASFinder) to identify tissue-specific, omics-determined sub-networks and the connections with their upstream regulator receptors to obtain a systems view of the differentiation of human adipocytes. Adipogenesis of human SBGS pre-adipocyte cells in vitro was monitored with a transcriptomic data set comprising six time points (0, 6, 48, 96, 192, 384 hours). To elucidate the mechanisms of adipogenesis, NASFinder was used to perform time-point analysis by comparing each time point against the control (0 h) and time-lapse analysis by comparing each time point with the previous one. NASFinder identified the coordinated activity of seemingly unrelated processes between each comparison, providing the first systems view of adipogenesis in culture. NASFinder has been implemented into a web-based, freely available resource associated with novel, easy to read visualization of omics data sets and network modules.

  19. Effects of type of physical exercise and leisure activities on the depression scores of obese Brazilian adolescent girls

    2005-11-01

    Full Text Available Several studies have indicated that depressive states may lead to hypokinesia with diminished metabolic rate and energy use. Hypokinesia associated with certain eating behaviors may lead to an unfavorable energy balance that can contribute to the emergence and prevalence of obesity among children and adults. The purpose of the present study was to examine the possibility of reducing depression inventory scores in female adolescents with third-degree obesity while testing the effectiveness of different exercise programs in reducing anxiety and depression scores. The sample consisted of 40 female subjects (mean age 16 ± 1.56 years divided into 4 groups (aerobic training, anaerobic training, leisure activities, and control. Subjects had a body mass index of 95% or more in relation to the 50th percentile. The aerobic program consisted of three ergometric bicycle sessions per week over a 3-month period (12 weeks and the activities were prescribed after determining the anaerobic ventilatory threshold (VO2 threshold. Anaerobic training was based on the Wingate anaerobic power test. The leisure program consisted of a varied range of activities (games, exercises, etc.. A nutritionist interviewed the members of these two groups and the control group every week in order to adapt them to the nutritional guidelines proposed for the study. The study showed that all three programs (aerobic exercise, anaerobic exercise and leisure activities were effective in reducing body mass. However, we found a significant reduction when analyzing the depression scores only for aerobic exercise (18.9 ± 9.33 to 10.6 ± 9.56 or 43.9% but no significant alterations for anaerobic exercise (11.36 ± 5.23 to 9.63 ± 4.78 or 15.22% and leisure (17.28 ± 7.55 to 15.07 ± 7.54 or 12.78%, thus indicating that in principle this type of activity could be included to improve emotional well-being of obese adolescent girls.

  20. Two new atom centered fragment descriptors and scoring function enhance classification of antibacterial activity.

    2014-04-01

    Classification of pharmacologic activity of a chemical compound is an essential step in any drug discovery process. We develop two new atom-centered fragment descriptors (vertex indices)--one based solely on topological considerations without discriminating atom or bond types, and another based on topological and electronic features. We also assess their usefulness by devising a method to rank and classify molecules with regard to their antibacterial activity. Classification performances of our method are found to be superior compared to two previous studies on large heterogeneous data sets for hit finding and hit-to-lead studies even though we use much fewer parameters. It is found that for hit finding studies topological features (simple graph) alone provide significant discriminating power, and for hit-to-lead process small but consistent improvement can be made by additionally including electronic features (colored graph). Our approach is simple, interpretable, and suitable for design of molecules as we do not use any physicochemical properties. The singular use of vertex index as descriptor, novel range based feature extraction, and rigorous statistical validation are the key elements of this study. PMID:24664120

    To develop an MRI enterography global score (MEGS) of Crohn's disease (CD) activity compared with a reference standard of faecal calprotectin (fC), C-reactive protein (CRP) and Harvey-Bradshaw index (HBI). Calprotectin, CRP and HBI were prospectively recorded for 71 patients (median age 33, male 35) with known/suspected CD undergoing MRI enterography. Two observers in consensus scored activity for nine bowel segments, grading mural thickness, T2 signal, mesenteric oedema, T1 enhancement and pattern, and haustral loss. Segmental scores were multiplied according to disease length. Five points each were added for lymphadenopathy, comb sign, fistulae and abscesses to derive the MEGS. A previously validated MRI CD activity score (CDAS) was also calculated. MRI scores were correlated with clinical references using Spearman's rank. A logistic regression diagnostic model was built to discriminate active (fC > 100 μg/g) from inactive disease. MEGS and CDAS were significantly correlated with fC (r = 0.46, P < 0.001) and (r = 0.39, P = 0.001) respectively. MEGS correlated with CRP (r = 0.39, P = 0.002). The model for discriminating active from inactive disease achieved an area under the receiver-operating curve of 0.75 and 0.66 after leave-one-out analysis. A magnetic resonance enterography global score (MEGS) of CD activity correlated significantly with fC levels. (orig.)

    2013-06-01

    Full Text Available Objective: To assess whether changes in dietary intake and physical activity pattern are associated with the annual body mass index (BMI z-score change among adolescents. Methods: The study was conducted in public schools in the city of Piracicaba, Sao Paulo, Brazil, with a probabilistic sample of 431 adolescents participating in wave I (2004 (hereafter, baseline and 299 in wave II (2005 (hereafter, follow-up. BMI, usual food intake, physical activity, screen time, sexual maturation and demographic variables were assessed twice. The association between annual change in food intake, physical activity, screen time, and annual BMI z-score changes were assessed by multiple regression. Results: The study showed a positive variation in BMI z-score over one-year. Among variables related to physical activity pattern only playing videogame and using computer increased over the year. The intake of fruits and vegetables and sugar-sweetened beverages increased over one year, while the others variables showed a reduction. An increased consumption of fatty foods (β = 0.04, p = 0.04 and sweetened natural fruit juices (β = 0.05, p = 0.03 was positively associated with the rise in BMI z-score. Conclusions: Unhealthy dietary habits can predict the BMI z-score gain more than the physical activity pattern. The intake of fatty foods and sweetened fruit juices is associated with the BMI z-score over one year.

  14. Activated TLR signaling in atherosclerosis among women with lower Framingham risk score: the multi-ethnic study of atherosclerosis.

    Chiang-Ching Huang

    Full Text Available BACKGROUND: Atherosclerosis is the leading cause of cardiovascular disease (CVD. Traditional risk factors can be used to identify individuals at high risk for developing CVD and are generally associated with the extent of atherosclerosis; however, substantial numbers of individuals at low or intermediate risk still develop atherosclerosis. RESULTS: A case-control study was performed using microarray gene expression profiling of peripheral blood from 119 healthy women in the Multi-Ethnic Study of Atherosclerosis cohort aged 50 or above. All participants had low (100 and carotid intima-media thickness (IMT >1.0 mm, whereas controls (N = 71 had CAC<10 and IMT <0.65 mm. We identified two major expression profiles significantly associated with significant atherosclerosis (odds ratio 4.85; P<0.001; among those with Framingham risk score <10%, the odds ratio was 5.30 (P<0.001. Ontology analysis of the gene signature reveals activation of a major innate immune pathway, toll-like receptors and IL-1R signaling, in individuals with significant atherosclerosis. CONCLUSION: Gene expression profiles of peripheral blood may be a useful tool to identify individuals with significant burden of atherosclerosis, even among those with low predicted risk by clinical factors. Furthermore, our data suggest an intimate connection between atherosclerosis and the innate immune system and inflammation via TLR signaling in lower risk individuals.

    2015-01-01

    The Annett Hand Preference Questionnaire (AHPQ) as modified by Briggs and Nebes was administered along with Carver and White's behavioural inhibition system (BIS) and behavioural activation system (BAS) scale and a shortened form of the Big Five personality questionnaire to 92 university students. After eliminating the data from five respondents who reported having changed handedness and one outlier, there was a significant sex difference in mean BIS scores, with females (n = 43) scoring higher than males (n = 43). Replicating the results of Wright, Hardie and Wilson, non-right-handers (n = 36) had significantly higher mean BIS score than right-handers (n = 50). Controlling for sex of participant, neuroticism and BAS sub-scale scores in hierarchical regression analyses left this BIS effect substantially unaffected. There was no handedness or sex difference on any of the three BAS sub-scales. Further analyses revealed no association between strength, as distinct from direction, of handedness and BIS (or BAS) scores. The findings are discussed with reference to recent developments in reinforcement sensitivity theory on which BIS/BAS variables are based. PMID:25697855

  19. Orbital magnetic resonance imaging combined with clinical activity score can improve the sensitivity of detection of disease activity and prediction of response to immunosuppressive therapy for Graves' ophthalmopathy

    The aim of this study was to demonstrate that the addition of orbital magnetic resonance (MR) imaging can provide improvement in sensitivity of detection of active disease and the prediction of the response to intravenous glucocorticoid therapy (ivGC), over clinical activity score (CAS) alone. A prospective case series was studied at our institution. Forty eight patients were examined by CAS and orbital MR imaging. The maximum of T2 relaxation times of extraocular muscles (maxT2RT) and other parameters were evaluated by MR imaging. Thirty five of 48 patients underwent ivGC. Twenty of 35 patients, whose CAS was 2 points or less, were evaluated for the response to ivGC. The correlation between CAS and maxT2RT was evaluated. Differentiation of active and inactive Graves' ophthalmopathy (GO) was performed by CAS and orbital MR imaging. The response to ivGC was evaluated by CAS, orbital MR imaging and ophthalmic parameters. As a result, CAS and maxT2RT showed significant positive correlation (r=0.58, p<0.0001), and 15 patients were positive by CAS and orbital MR imaging. However, 20 patients were positive by only MR imaging. In those 20 patients, there was significant improvement after ivGC. We concluded that orbital MR imaging combined with CAS could improve the sensitivity of detection of active disease and the prediction of the response to ivGC. In addition, even if only one parameter of CAS is positive, further examination with orbital MR imaging is advised. (author)

    BACKGROUND/OBJECTIVES Although the association of body mass index (BMI) with metabolic syndrome (MetS) is well documented, there is little knowledge on the independent and joint associations of BMI and physical activity with MetS risk based on a continuous scoring system. This study was designed to explore the effect of physical activity on interactions between excess body weight and continuous metabolic syndrome (cMetS) in a nationwide survey of Iranian children and adolescents. SUBJECTS/METHODS Data on 5,625 school students between 10 and 18 years of age were analyzed. BMI percentiles, screen time activity (STA), leisure time physical activity (LTPA) levels, and components of cMetS risk score were extracted. Standardized residuals (z-scores) were calculated for MetS components. Linear regression models were used to study the interactions between different combinations of cMetS, LTPA, and BMI percentiles. RESULTS Overall, 984 (17.5%) subjects were underweight, whereas 501 (8.9%) and 451 (8%) participants were overweight and obese, respectively. All standardized values for cMetS components, except fasting blood glucose level, were directly correlated with BMI percentiles in all models (P-trend < 0.001); these associations were independent of STA and LTPA levels. Linear associations were also observed among LTPA and standardized residuals for blood pressure, high-density lipoprotein, and waist circumference (P-trend < 0.01). CONCLUSIONS Our findings suggest that BMI percentiles are associated with cMetS risk score independent of LTPA and STA levels. PMID:26244080

Physical inactivity in COPD patients is a crucial risk factor for OP; the COPD assessment test (CAT is the newest assessment tool for the health status and daily activities of COPD patients. This study investigated the relationship among daily physical activity (DPA, CAT scores, and bone mineral density (BMD in COPD patients with or without OP. This study included 30 participants. Ambulatory DPA was measured using actigraphy and oxygen saturation by using a pulse oximeter. BMD was measured using dual-energy X-ray absorptiometry. OP was defined as a T-score (standard deviations from a young, sex-specific reference mean BMD less than or equal to -2.5 SD for the lumbar spine, total hip, and femoral neck. We quantified oxygen desaturation during DPA by using a desaturation index and recorded all DPA, except during sleep. COPD patients with OP had lower DPA and higher CAT scores than those of patients without OP. DPA was significantly positively correlated with (lumbar spine, total hip, and femoral neck BMD (r=0.399, 0.602, 0.438, respectively

  9. Fetal Biophysical Profile Scoring

    H.R. HaghighatKhah

    2009-01-01

    significance. Fetal breathing movements, amniotic fluid volume, and the non-stress test are the most powerful variables. For example, when the biophysical profile score is 2, the perinatal mortality varies between 428/1000 with only fetal movement present to 66/1000 if the non-stress test is reactive and all of the ultrasound parameters are absent (Manning 1990b. Some authors have, therefore, proposed utilization of a modified biophysical profile that incorporates only the non-stress test and amniotic fluid volume (Miller 1996. Although the positive predictive value of these 2 tests is equivalent to a biophysical profile score of 6, the perinatal mortality is still increased over a normal test score of 8 or 10 (Manning 1990b. The false positive rate with the modified biophysical profile score is also substantially higher. "nConclusions: The fetus expresses its well being or compromised status through a number of different biophysical activities that are controlled by different central nervous system centers. The utilization of the biophysical score for antepartum surveillance in high-risk patients has resulted in a reduction in perinatal mortality when compared to historical controls. The appropriate management of the viable fetus with an abnormal biophysical profile score may also decrease long-term neurological morbidity (Manning 1998. "nIt is unlikely that in the future additional variables will be added to the biophysical profile score. However, perhaps the incorporation of the fetal state (i.e., eye movements and Doppler flow studies of specific fetal vessels (umbilical artery, middle cerebral artery, ductus venosus will be incorporated into a complete assessment of the fetal condition "n "nTable 1.

    Objectives To better understand the effectiveness of xylitol in caries prevention in adults, and to attempt improved clinical trial efficiency. Methods As part of the Xylitol for Adult Caries Trial (X-ACT), non-cavitated and cavitated caries lesions were assessed in subjects who were experiencing the disease. The trial was a test of the effectiveness of 5 grams/day of xylitol, consumed by dissolving in the mouth five 1 gram lozenges spaced across each day, compared with a sucralose placebo. For this analysis, seeking trial efficiency, 538 subjects aged 21–80, with complete data for four dental examinations were selected from the 691 randomized into the three year trial, conducted at three sites. Acceptable inter and intra examiner reliability before and during the trial was quantified using the kappa statistic. Results The mean annualized non-cavitated plus cavitated lesion transition scores in coronal and root surfaces, from sound to carious favoured xylitol over placebo, during the three cumulative periods of 12, 24, and 33 months, but these clinically and statistically non-significant differences declined in magnitude over time. Restricting the present assessment to those subjects with a higher baseline lifetime caries experience showed possible but inconsistent benefit. Conclusions There was no clear and clinically relevant preventive effect of xylitol on caries in adults with adequate fluoride exposure when non-cavitated plus cavitated lesions were assessed. This conformed to the X-ACT trial result assessing cavitated lesions. Including non-cavitated lesion assessment in this full scale, placebo controlled, multi site, randomized, double blinded clinical trial in adults experiencing dental caries, did not achieve added trial efficiency or demonstrate practical benefit of xylitol.

  13. Decompositions of Proper Scores

    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...

    2015-06-01

    Full Text Available Health-related quality of life (HRQL for nursing home residents is important, however, the concept of quality of life is broad, encompasses many domains and is difficult to assess in people with dementia. Basic activities of daily living (ADL are measured routinely in nursing homes using the Resident Assessment Instrument-Minimum Data Set Version 2.0 (RAI-MDS and Functional Independence Measure (FIM instrument. We examined the relationship between HRQL and ADL to assess the future possibility of ADL dependency level serving as a surrogate measure of HRQL in residents with dementia. To assess ADL, measures derived from the RAI-MDS and FIM data were gathered for 111 residents at the beginning of our study and at 6-month follow-up. Higher scores for independence in ADL were correlated with higher scores for a disease-specific HRQL measure, the Quality of Life—Alzheimer’s Disease Scale. Preliminary evidence suggests that FIM-assessed ADL is associated with HRQL for these residents. The associations of the dressing and toileting items with HRQL were particularly strong. This finding suggests the importance of ADL function in HRQL. The RAI-MDS ADL scales should be used with caution to evaluate HRQL.

    2011-04-01

    Full Text Available Cada vez es más necesario disponer de instrumentos de medida en el ámbito de la salud que se puedan utilizar en la práctica clínica e investigación. Para garantizar la calidad de su medición es imprescindible que los instrumentos sean sometidos a un proceso de validación. Este proceso consiste en adaptar culturalmente un instrumento al medio donde se quiere administrar y comprobar sus características psicométricas como: fiabilidad, validez, sensibilidad y factibilidad. Hay instrumentos de medida del ámbito de la salud, disponibles en otros idiomas pero sin validar al español. Además la metodología para validar un instrumento es poco conocida por profesionales sanitarios, lo que explica el uso indiscriminado de instrumentos sólo adaptados o validados de manera poco consistente. El objetivo de esta revisión es realizar una puesta al día del proceso de validación de un instrumento de medida de la salud y en qué consiste de manera práctica. La accesibilidad de instrumentos de evaluación adaptados culturalmente y validados en distintos idiomas facilitará comparar resultados obtenidos con el mismo instrumento y desarrollar estudios internacionales en distintas culturas.

  20. Fingerprinting of music scores

    Irons, Jonathan; Schmucker, Martin

    2004-06-01

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

Conclusions. mMRIA was comparable to MRIA in the evaluation of disease activity in Crohn's disease. PMID:26759554

  4. Neutrophil-lymphocyte ratio, pain perception, and disease activity score may serve as important predictive markers for sustained remission in rheumatoid arthritis

    S. Chandrashekara

    2016-02-01

    Full Text Available The implementation of new treatment strategies based on current recommendations has enabled a greater number of patients with rheumatoid arthritis (RA to achieve remission. However, there are no definite predictors of sustained remission. Moreover, the absence of clear consensus on the time of withdrawal or reduction of treatment further adds to the treatment burden. This pilot study was intended to evaluate the prognostic potential of various RA-related parameters. All the enrolled subjects (n=124 were clinically evaluated on the basis of various parameters including age, gender, duration of illness before the initiation of disease-modifying anti-rheumatic drugs, tender and swollen joints (28 joints, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP, hemoglobin percentage, lymphocyte count, total white-blood cell counts, and neutrophil to lymphocyte ratio (NLR. Student’s t-test and discriminant function analysis were performed. The specificity of all parameters and their best possible cut-off to predict relapse were calculated using the receiver operating characteristic (ROC analysis. A significant difference in terms of pain perception, NLR, tendency to have a significant tender joint count and absolute lymphocyte counts was identified between the patients in sustained remission and those in relapse. The ROC analysis indicated that NLR was consistent in predicting remission. CRP, ESR, and/or disease activity score may not be very effective in differentiating patients with sustainable remission/low disease activity. NLR along with patient’s perception of pain may assist in predicting sustained remission.

    Lilian A. Y. Fernandes

    2014-12-01

    Full Text Available BACKGROUND: Knowing the potential for and limitations of information generated using different evaluation instruments favors the development of more accurate functional diagnoses and therapeutic decision-making. OBJECTIVE: To investigate the relationship between the number of compensatory movements when climbing up and going down stairs, age, functional classification and time taken to perform a tested activity (TA of going up and down stairs in boys with Duchenne muscular dystrophy (DMD. METHOD: A bank of movies featuring 30 boys with DMD performing functional activities was evaluated. Compensatory movements were assessed using the climbing up and going down stairs domain of the Functional Evaluation Scale for Duchenne Muscular Dystrophy (FES-DMD; age in years; functional classification using the Vignos Scale (VS, and TA using a timer. Statistical analyses were performed using the Spearman correlation test. RESULTS: There is a moderate relationship between the climbing up stairs domain of the FES-DMD and age (r=0.53, p=0.004 and strong relationships with VS (r=0.72, p=0.001 and TA for this task (r=0.83, p<0.001. There were weak relationships between the going down stairs domain of the FES-DMD-going down stairs with age (r=0.40, p=0.032, VS (r=0.65, p=0.002 and TA for this task (r=0.40, p=0.034. CONCLUSION: These findings indicate that the evaluation of compensatory movements used when climbing up stairs can provide more relevant information about the evolution of the disease, although the activity of going down stairs should be investigated, with the aim of enriching guidance and strengthening accident prevention. Data from the FES-DMD, age, VS and TA can be used in a complementary way to formulate functional diagnoses. Longitudinal studies and with broader age groups may supplement this information.

  18. Fatty acid composition in serum correlates with that in the liver and non-alcoholic fatty liver disease activity scores in mice fed a high-fat diet.

    Wang, Xing-He; Li, Chun-Yan; Muhammad, Ishfaq; Zhang, Xiu-Ying

    2016-06-01

    In this study, we investigated the correlation between the serum fatty acid composition and hepatic steatosis, inflammation, hepatocellular ballooning scores, and liver fatty acids composition in mice fed a high-fat diet. Livers were collected for non-alcoholic fatty liver disease score analysis. Fatty acid compositions were analysed by gas chromatography. Correlations were determined by Pearson correlation coefficient. Exposed to a high-fat diet, mice developed fatty liver disease with varying severity without fibrosis. The serum fatty acid variation became more severe with prolonged exposure to a high-fat diet. This variation also correlated significantly with the variation in livers, with the types of fatty acids corresponding to liver steatosis, inflammation, and hepatocellular ballooning scores. Results of this study lead to the following hypothesis: the extent of serum fatty acid variation may be a preliminary biomarker of fatty liver disease caused by high-fat intake. PMID:27179602

    2013-01-01

    Background Subjective assessment tools such as visual analog scales (VAS) or pain scores are commonly used to evaluate the intensity of chronic cancer-induced pain.However,their value is limited in some cases.We measured changes in VAS pain scores and salivary a-amylase (sAA) concentrations in cancer patients receiving radiotherapy for bone metastases to ascertain the correlation between these measures.Methods We enrolled 30 patients with bone metastases attending a single institution from June 2010 to March 2011.All patients with cancer-induced bone pain received radiation therapy (RT) at the same dose (30 Gy) and fractionation (3 Gy/ fraction,5 days/week) for palliative pain relief.We assessed heart rate (HR),systolic and diastolic blood pressures (DBP/SBP) and VAS pain scores before (d0) and after five (d5) and ten fractions (d10) of irradiation,sAA and salivary cortisol (SC)concentrations were measured using a portable analyzer and automated chemiluminescence analyzer,respectively.Results Radiotherapy markedly decreased VAS scores from (82.93±9.29) to (31.43±t16.73) mm (P <0.001) and sAA concentrations from (109.40±26.38) to (36.03±19.40) U/ml (P <0.001).Moreover,there was a significant correlation between these two indices (P <0.01,r=0.541).HR decreased by 6.5% after radiotherapy,but did not correlate with VAS scores (P >0.05).SC concentrations and BP did not change significantly during the study (P >0.05).Conclusions The significant correlation between sAA concentrations and VAS pain scores identified in these preliminary results suggests that this biomarker may be a valuable,noninvasive and sensitive index for the objective assessment of pain intensity in patients with cancer-induced bone pain.

    2007-11-01

    Full Text Available Abstract Background Clinical guidelines for the management of back pain frequently recommend 'manual therapy' as a first line intervention, with psychosocial screening and 'active rehabilitation' for those not improving at 6 weeks post onset. The potential for psychosocial factors to predict treatment response and therefore outcome has not been adequately explored. The purpose of this pilot study was to determine the feasibility of a study to compare manual therapy and active rehabilitation outcomes for subjects with sub-acute/chronic back pain, investigate whether any difference in outcome was related to psychosocial factors, and to inform the design of a main study. Methods A convenience sample of 39 patients with non-specific low back pain referred to the physiotherapy department of an acute NHS Trust hospital was recruited over a nine month period. Patients completed the Linton and Hallden psychological screening questionnaire (LH and were allocated to a low LH (105 or below or high LH (106 or above scoring group. The low or high LH score was used to sequentially allocate patients to one of two treatment groups – Manual Therapy comprising physiotherapy based on manual means as chosen by the treating therapist or Active Rehabilitation comprising a progressive exercise and education programme – with the first low LH scoring patient being allocated to active rehabilitation and the next to manual therapy and so on. Treatment was administered for eight sessions over a four-week period and outcome measures were taken at baseline and at four weeks. Measures used were the Roland Morris Questionnaire (RMQ, two components of the Short Form McGill (total pain rating index [PRI] and pain intensity via visual analogue scale [VAS], and the LH. Results The manual therapy group demonstrated a greater treatment effect compared with active rehabilitation for RMQ (mean difference 3.6, 95% CI 1.1 – 6.2, p = 0.006 and PRI (7.1, 95% CI 2.0 – 12.2, p = 0

    Full Text Available Background. There is a need for tools to assess dependency among persons with severe impairments. Objectives. The aim was to compare the Functional Independence Measure (FIM and the Northwick Park Dependency Score (NPDS, in a sample from in-patient rehabilitation. Material and Methods. Data from 115 persons (20 to 65 years of age with neurological impairments was gathered. Analyses were made of sensitivity, specificity, positive predictive value, and negative predictive value. Agreement of the scales was assessed with kappa and concordance with Goodman-Kruskal’s gamma. Scale structures were explored using the Rank-Transformable Pattern of Agreement (RTPA. Content validation was performed. Results. The sensitivity of the NPDS as compared to FIM varied between 0.53 (feeding and 1.0 (mobility and specificity between 0.64 (mobility and 1.0 (bladder. The positive predictive value varied from 0.62 (mobility to 1.0 (bladder, and the negative predictive value varied from 0.48 (bowel to 1.0 (mobility. Agreement between the scales was moderate to good (four items and excellent (three items. Concordance was good, with a gamma of −.856, an asymptotic error (ase of .025, and P<.000. The parallel reliability between the FIM and the NPDS showed a tendency for NPDS to be more sensitive (having more categories when dependency is high. Conclusion. FIM and NPDS complement each other. NPDS can be used as a measure for severely injured patients who are sensitive when there is a high need of nursing time.

  10. Credit Scoring Modeling

    Siana Halim

    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 objective of this study was to use high-resolution computed tomography (HRCT) imaging to predict the presence of smear-positive active pulmonary tuberculosis (PTB) in elderly (at least 65 years of age) and non-elderly patients (18-65 years of age). Patients with active pulmonary infections seen from November 2010 through December 2011 received HRCT chest imaging, sputum smears for acid-fast bacilli and sputum cultures for Mycobacterium tuberculosis. Smear-positive PTB was defined as at least one positive sputum smear and a positive culture for M. tuberculosis. Multivariate logistic regression analyses were performed to determine the HRCT predictors of smear-positive active PTB, and a prediction score was developed on the basis of receiver operating characteristic curve analysis. Of 1,255 patients included, 139 were diagnosed with smear-positive active PTB. According to ROC curve analysis, the sensitivity, specificity, positive predictive value, negative predictive value, false positive rates and false negative rates were 98.6 %, 95.8 %, 78.5 %, 99.8 %, 4.2 % and 1.4 %, respectively, for diagnosing smear-positive active PTB in elderly patients, and 100.0 %, 96.9 %, 76.5 %, 100.0 %, 3.1 % and 0.0 %, respectively, for non-elderly patients. HRCT can assist in the early diagnosis of the most infectious active PTB, thereby preventing transmission and minimizing unnecessary immediate respiratory isolation. (orig.)

    Abarca Araya, Steven

    2013-05-01

    Full Text Available Resumen: El presente ensayo surgió de una revisión bibliográfica que permitió conocer los alcances y las limitaciones de utilizar la Internet y las redes sociales como instrumento de mediación pedagógica. La Internet y las redes sociales han pasado a ocupar un espacio preponderante en la sociedad actual, utilizándose para promover bienes, servicios, entretenimiento y, en algunos casos, como instrumento de mediación pedagógica. Como resultado de la revisión realizada se pudo constatar que la utilización de las redes sociales como instrumento de mediación pedagógica ha permitido identificar sus bondades como mayor cobertura, asincronía en la mediación, aprendizaje colaborativo, aprendizaje autónomo, entre otros. Sin embargo, en contraste con las bondades que presenta, también tiene sus limitación es como la falta de pericia de docentes y estudiantes en el uso de la tecnología, el acceso, mayor inversión de tiempo en la mediación pedagógica, la renuencia de algunas personas al uso de la tecnología, la dificultad para controlar si es realmente el estudiante quien participa en las actividades pedagógicas, entre otros. Se concluye que todavía es muy apresurado hacer conjeturas acerca del futuro que le espera al uso de las redes sociales como instrumento de mediación pedagógica, pues algunos de estos alcances y limitaciones irán desapareciendo conforme vayamos adquiriendo mayor experiencia en su utilización, y su presencia sea cotidiana en nuestro sistema educativo, mientras que otros se seguirán manteniendo o, incluso, se pueden incrementar, por lo que debe analizarse su uso a la luz del contexto y la realidad de cada institución educativa.Abstract: This essay emerged from a literature review that yielded information on the scope and limitations of using the Internet and social media as a tool for teaching mediation.

    Full Text Available Abstract Background Pharmacological and genetic studies suggest the importance of the dopaminergic, serotonergic, and noradrenergic systems in the pathogenesis of Attention Deficit Hyperactivity Disorder (ADHD and Disruptive Behavior Disorder (DBD. We have, in a population-based sample, studied associations between dimensions of the ADHD/DBD phenotype and Monoamine Oxidase B (MAO-B activity in platelets and polymorphisms in two serotonergic genes: the Monoamine Oxidase A Variable Number of Tandem Repeats (MAO-A VNTR and the 5-Hydroxytryptamine Transporter gene-Linked Polymorphic Region (5-HTT LPR. Methods A population-based sample of twins, with an average age of 16 years, was assessed for ADHD/DBD with a clinical interview; Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL. Blood was drawn from 247 subjects and analyzed for platelet MAO-B activity and polymorphisms in the MAO-A and 5-HTT genes. Results We found an association in girls between low platelet MAO-B activity and symptoms of Oppositional Defiant Disorder (ODD. In girls, there was also an association between the heterozygote long/short 5-HTT LPR genotype and symptoms of conduct disorder. Furthermore the heterozygote 5-HTT LPR genotype in boys was found to be associated with symptoms of Conduct Disorder (CD. In boys, hemizygosity for the short MAO-A VNTR allele was associated with disruptive behavior. Conclusion Our study suggests that the serotonin system, in addition to the dopamine system, should be further investigated when studying genetic influences on the development of Disruptive Behavior Disorders.

    Full Text Available El presente estudio es de tipo descriptivo metodológico con abordaje cuantitativo; tuvo como objetivo determinar la validez de constructo y confiabilidad del instrumento “Factores que influyen en la adherencia al tratamiento farmacológico y no farmacológico en pacientes con factores de riesgo de enfermedad cardiovascular”. Para obtener la información se aplicó el instrumento, diseñado por Bonilla y De Reales en al año 2006, conformado por 53 ítems y cuatro dimensiones, la cual cuenta con validez facial, de contenido y confiabilidad a 485 pacientes que cumplían los criterios de inclusión. Al instrumento se le realizó la validez de constructo por medio del análisis factorial de tipo exploratorio para determinar la correlación entre las variables y las cuatro dimensiones, por el método de extracción de componentes principales y rotación varimax con Kaiser. La consistencia interna del instrumento se realizó con los resultados que arrojó el análisis factorial (24 ítems y 4 dimensiones, a través del coeficiente alfa de Cronbach. Los resultados del estudio mostraron que la validez de constructo realizada al instrumento permitió reducir el número de ítems de 53 a 24 a través del análisis factorial, sin afectar las 4 dimensiones del instrumento; el índice de consistencia interna por medio del método del alfa de Cronbach fue de 0,60, lo cual se considera adecuado. Con la exclusión de los 29 ítems se generó una nueva versión del instrumento, que agrupa los 24 ítems en cuatro factores que explican el 45% de la varianza, lo que demostró que las variables se correlacionaban con lo que se pretendía medir, permitiendo sustentar teóricamente el constructo, haciéndolo más práctico en su aplicabilidad para los profesionales de enfermería en diferentes escenarios de cuidado. Esto demuestra que el instrumento es válido y confiable, y se puede aplicar en futuros estudios acerca de la adherencia, a fin de obtener una mejor

    2011-04-01

    Full Text Available A literatura mostra a importância da identificação precoce de sinais de atraso no desenvolvimento infantil e a dificuldade na escolha de instrumentos de avaliação. Os objetivos foram comparar o Denver II e a EDC com uma escala de referência (EEDP quanto à identificação de crianças com atraso de desenvolvimento, verificar diferença nos resultados considerando gênero dos participantes e averiguar a convergência dos resultados das escalas. Participaram 24 bebês de cinco a onze meses, de ambos os sexos, frequentadores de creches municipais. Os instrumentos foram aplicados individualmente e em sequência pré-definida. A análise estatística revelou que a escala EDC e o Denver II não podem ser considerados semelhantes à escala EEDP. Quanto ao gênero, não houve diferença significativa. Não houve convergência de itens falhos segundo as áreas. Assim, é importante ter cautela na escolha de instrumentos para triagem e obter informações de diferentes fontes sobre o desenvolvimento da criança.

    Full Text Available En este artículo nos centraremos en la evaluación neuropsicológica como proceso consistente en la utilización de diversas técnicas clínicas, psicométricas o neurológicas para conocer las peculiaridades del procesamiento en población normal y en personas que presentan algún trastorno, lesión o disfunción en el sistema nervioso. Analizaremos inicialmente qué se entiende por evaluación neuropsicológica, los ámbitos que toda evaluación neuropsicológica debe abarcar y que nos va a permitir obtener un perfil neuropsicológico comprehensivo. En coherencia con los ámbitos de exploración, analizamos los instrumentos que deben ser utilizados. Estos instrumentos pueden ser divididos en dos clases: instrumentos que, no habiéndose creado con una finalidad neuropsicológica, son utilizados en este campo con la intención de conocer el sustrato neurológico subyacente, y baterías de evaluación neuropsicológica propiamente dichas, tomando como referencia de ellas, la batería Luria-DNA.

    mantener la alegría. Se sugiere que estudios futuros sean conducidos con base en el instrumento desarrollado, teniendo en cuenta contribuir para su refinamiento.This study is aimed at both describing the steps of construction of a qualitative instrument to investigate the emotional regulation strategies of Brazilian students, and reporting preliminary results. The sample was composed of 54 third and fourth grade basic education students of a public school in Campinas. The instrument consists of a 24 interview questions grouped into four emotions: sadness, anger, fear and happiness. It also includes eight boards with pictures of children expressing each of the emotions investigated. Students' answers to interview questions were studied through content analysis. A system of categories was developed for each question and the reliability of the coding procedures was evaluated by two independent raters. The percentage of agreement between them was acceptable. The results showed that engagement in pleasant activities was the most frequent strategy to deal with sadness, anger, fear and to keep happiness. Future studies employing this instrument should be carried out to better refine it.

    Full Text Available Abstract Background Many Australian children are insufficiently active to accrue health benefits and physical activity (PA levels are consistently lower among youth of low socio-economic position. PA levels decline dramatically during adolescence and evidence suggests that competency in a range of fundamental movement skills (FMS may serve as a protective factor against this trend. Methods/design The Supporting Children’s Outcomes Using Rewards Exercise and Skills (SCORES intervention is a multi-component PA and FMS intervention for primary schools in low-income communities, which will be evaluated using a group randomized controlled trial. The socio-ecological model provided a framework for the 12-month intervention, which includes the following components: teacher professional learning, student leadership workshops (including leadership accreditation and rewards, e.g., stickers, water bottles, PA policy review, PA equipment packs, parental engagement via newsletters, FMS homework and a parent evening, and community partnerships with local sporting organizations. Outcomes will be assessed at baseline, 6- and 12-months. The primary outcomes are PA (accelerometers, FMS (Test of Gross Motor Development II and cardiorespiratory fitness (multi-stage fitness test. Secondary outcomes include body mass index [using weight (kg/height (m2], perceived competence, physical self-esteem, and resilience. Individual and environmental mediators of behavior change (e.g. social support and enjoyment will also be assessed. The System for Observing Fitness Instruction Time will be used to assess the impact of the intervention on PA within physical education lessons. Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA behavior change will be explored. Discussion SCORES is an innovative primary school-based PA and FMS intervention designed to support students attending schools in low-income communities to be more skilled

    Feldman, Michal; Meir, Reshef; Tennenholtz, Moshe

    2011-01-01

    We introduce a measure for the level of stability against coalitional deviations, called \\emph{stability scores}, which generalizes widely used notions of stability in non-cooperative games. We use the proposed measure to compare various Nash equilibria in congestion games, and to quantify the effect of game parameters on coalitional stability. For our main results, we apply stability scores to analyze and compare the Generalized Second Price (GSP) and Vickrey-Clarke-Groves (VCG) ad auctions....

  3. The scoring of movements in sleep.

    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.

  4. Correlation of signal intensity ratio on orbital MRI-TIRM and clinical activity score as a possible predictor of therapy response in Graves' orbitopathy - a pilot study at 1.5 T

    This study seeks to describe the predictive value of the signal intensity ratio (SIR) in magnetic resonance imaging-turbo inversion recovery magnitude (MRI-TIRM) in patients with Graves' orbitopathy (GO) with regard to predictability of therapy response. Included in this prospective pilot study were 36 consecutive patients with GO and 25 control subjects. Patients were clinically assessed according to the European Group on Graves' Orbitopathy recommendations with active GO defined by a clinical activity score (CAS) ≥ 3. On magnetic resonance (MR) imaging, muscle inflammation was measured with a region of interest set within the brightest extra-ocular muscle both on coronal turbo inversion recovery magnitude (TIRM) and on fat suppressed gadolinium-enhanced T1-weighted sequences. To calculate the SIR, the measured signal intensity was set in proportion to that of the ipsilateral temporalis muscle. Signal intensity ratio in coronal T2-weighted TIRM sequences in either group ranged from 1.22 to 4.92 (mean 2.04) in patients with GO and from 1.18 to 2.4 (mean 1.63) in controls without GO. The observed differences were significant on the TIRM sequences (right eye p = 0.023; left eye p = 0.022), whereas, no significant differences could be detected on the T1-weighted sequences (right eye p = 0.396; left eye p = 0.498). A cut off value of SIR > 2.5 for a CAS ≥ 4 to discriminate active from inactive patients was statistically calculated. T2 relaxation time is a reliable tool in detecting active GO. The difference in T2-SIR versus T1-SIR is helpful to distinguish inflammatory oedema of the extra ocular muscles from intra-orbital congestion due to reduced venous outflow. (orig.)

    Full Text Available Juridical instruments of pollution control are important components of the public politics related to natural resources and public health. In certain conditions, those instruments can be used to assure the public politics mentioned. The Brazilian juridical system hsa those instruments available to confront the possibility or the occurrence of the pollution for pesticides. Initial analysis of basic notions and terminology involved justify themselves because of the importance of the research activity and its evaluation. Those are used so much in documents, as in another bibliographical source, that it can be understood in many ways. It includes relationship of dates, facts and geopolitics situation concerning about the theme, and it comments, besides the implication with the social reaction to that pollution type. The new interpretations of the parameters of application has to be proposed and defended by the juridical responsability and the pesticide's registration concerning right. Basic references taken to sustainable development approach and the precautionary approach, both inserted in the Brazilian positive juridical system as it bases. It is still recognized in the Brazilian context the lack of control instruments for pesticides pollution that they did not include in the repressive group or control bureaucratic through the licensing. It was verified that the financial mechanismsmotivated the pesticides' employment, as well as rural credit. = Importantes componentes das políticas públicas relacionadas aos recursos naturais e à saúde pública, os instrumentos jurídicos de controle de poluição, em determinadas condições, podem ser utilizados para assegurar a efetivação dessas políticas.

  7. 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

  1. LAS REDES SOCIALES COMO INSTRUMENTO DE MEDIACIÓN PEDAGÓGICA: ALCANCES Y LIMITACIONES

    Steven Abarca Araya

    2013-01-01

    Full Text Available El presente ensayo surgió de una revisión bibliográfica que permitió conocer los alcances y las limitaciones de utilizar la Internet y las redes sociales como instrumento de mediación pedagógica. La Internet y las redes sociales han pasado a ocupar un espacio preponderante en la sociedad actual, utilizándose para promover bienes, servicios, entretenimiento y, en algunos casos, como instrumento de mediación pedagógica. Como resultado de la revisión realizada se pudo constatar que la utilización de las redes sociales como instrumento de mediación pedagógica ha permitido identificar sus bondades como mayor cobertura, asincronía en la mediación, aprendizaje colaborativo, aprendizaje autónomo, entre otros. Sin embargo, en contraste con las bondades que presenta, también tiene sus limitación es como la falta de pericia de docentes y estudiantes en el uso de la tecnología, el acceso, mayor inversión de tiempo en la mediación pedagógica, la renuencia de algunas personas al uso de la tecnología, la dificultad para controlar si es realmente el estudiante quien participa en las actividades pedagógicas, entre otros. Se concluye que todavía es muy apresurado hacer conjeturas acerca del futuro que le espera al uso de las redes sociales como instrumento de mediación pedagógica, pues algunos de estos alcances y limitaciones irán desapareciendo conforme vayamos adquiriendo mayor experiencia en su utilización, y su presencia sea cotidiana en nuestro sistema educativo, mientras que otros se seguirán manteniendo o, incluso, se pueden incrementar, por lo que debe analizarse su uso a la luz del contexto y la realidad de cada institución educativa.

    Full Text Available OBJETIVO: Analisar instrumento de medição da adesão ao tratamento da hipertensão por meio da "Teoria da Resposta ao Item". MÉTODOS: Estudo analítico com 406 hipertensos com complicações associadas, atendidos na atenção básica em Fortaleza, CE, 2011, pela "Teoria da Resposta ao Item". As etapas de execução foram: teste de dimensionalidade, calibração dos itens; tratamento dos dados e construção da escala, analisadas com base no modelo de resposta gradual. Estudo da dimensionalidade do instrumento foi feito pela análise da matriz de correlação policórica e análise fatorial de informação completa. Utilizou-se o software Multilog para calibração dos itens e estimação dos escores. RESULTADOS: Os itens referentes ao tratamento medicamentoso foram os mais diretamente relacionados à adesão, enquanto aqueles referentes ao tratamento não medicamentoso precisam ser reformulados, pois possuíram menor quantidade de informação psicométrica e baixa discriminação. A independência dos itens, o reduzido número de níveis da escala e as baixas variâncias explicadas no ajuste dos modelos mostraram as principais fragilidades do instrumento analisado. A "Teoria da Resposta ao Item" mostrou-se relevante para análise, pois avaliou o respondente quanto à adesão ao tratamento da hipertensão, ao nível de dificuldade dos itens e à sua capacidade de discriminação entre indivíduos com diferentes níveis de adesão, o que gerou maior quantidade de informação. CONCLUSÕES: O instrumento analisado é limitado para medir a adesão ao tratamento da hipertensão, mediante análise pela "Teoria da Resposta ao Item", e necessita de ajustes. A adequada formulação dos itens é importante para medir precisamente o traço latente desejado.

    Full Text Available Los Atlas de Riesgos municipales constituyen uno de los instrumentos que el gobierno mexicano ha privilegiado en los últimos años, con la finalidad de apoyar el ordenamiento de los asentamientos humanos en México. Este artículo recupera los principales antecedentes conceptuales, metodológicos, institucionales y legales de estos productos cartográficos, y analiza sus alcances y limitaciones reales en cuanto instrumentos de regulación de usos de suelo y gestión de riesgo en el caso mexicano. Para ello, utiliza los conceptos de juridificación, cumplimiento de marcos normativos (enforcement y gestión multi-escalar, con el objeto de analizar las condiciones en las que estos atlas surgen como dispositivos jurídicos en el contexto de una descentralización parcial del ordenamiento teritorial y la protección civil, así como la distancia que los separa de los efectos territoriales esperados de ellos. El artículo sustenta las razones para la relativa inoperancia de los atlas en el contexto de los gobiernos municipales; entre estas razones destacan la indefinición en el marco legal sobre su contenido y uso; la falta de claridad sobre las instancias responsables de su implementación, y la carencia de sanciones que conlleva su incumplimiento en la mayoría de las legislaciones estatales.

  18. Sobre o uso da sublimação como instrumento para uma "metapsicologia da arte"

    Marcel Santiago Soares

    2014-01-01

    Full Text Available Neste artigo investigaremos a noção freudiana de sublimação e seu uso como mecanismo explicativo para os processos artísticos. Notaremos que, pela sua construção, aliás, confusa e carente de formalização conceitual, é impossível separar a sublimação do campo clínico no qual nasce e no qual encontra sua potência, como descrição de uma vicissitude e de uma possibilidade de lidar com a pulsão. Dessa forma, proporemos uma delimitação de qualquer "metapsicologia da arte" como instrumento clínico, antes que como instrumento de análise ou crítica da arte. Não obstante, notaremos a influência recíproca entre a psicanálise e a estética de seu tempo.

    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.

    Traumatic injuries frequently lead to infection, organ failure, and death. Health care providers rely on several injury scoring systems to quantify the extent of injury and to help predict clinical outcome. Physiological, anatomical, and clinical laboratory analytic scoring systems (Acute Physiology and Chronic Health Evaluation [APACHE], Injury Severity Score [ISS]) are utilized, with limited success, to predict outcome following injury. The recent development of techniques for measuring the expression level of all of a person’s genes simultaneously may make it possible to develop an injury scoring system based on the degree of gene activation. We hypothesized that a peripheral blood leukocyte gene expression score could predict outcome, including multiple organ failure, following severe blunt trauma. To test such a scoring system, we measured gene expression of peripheral blood leukocytes from patients within 12 h of traumatic injury. cRNA derived from whole blood leukocytes obtained within 12 h of injury provided gene expression data for the entire genome that were used to create a composite gene expression score for each patient. Total blood leukocytes were chosen because they are active during inflammation, which is reflective of poor outcome. The gene expression score combines the activation levels of all the genes into a single number which compares the patient’s gene expression to the average gene expression in uninjured volunteers. Expression profiles from healthy volunteers were averaged to create a reference gene expression profile which was used to compute a difference from reference (DFR) score for each patient. This score described the overall genomic response of patients within the first 12 h following severe blunt trauma. Regression models were used to compare the association of the DFR, APACHE, and ISS scores with outcome. We hypothesized that patients with a total gene response more different from uninjured volunteers would tend to have poorer

    Kleinberg, Jon; Raghu, Maithra

    2015-01-01

    Team performance is a ubiquitous area of inquiry in the social sciences, and it motivates the problem of team selection -- choosing the members of a team for maximum performance. Influential work of Hong and Page has argued that testing individuals in isolation and then assembling the highest-scoring ones into a team is not an effective method for team selection. For a broad class of performance measures, based on the expected maximum of random variables representing individual candidates, we...

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

    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 Os autores compararam a resistência à torção entre os instrumentos rotatórios de níquel-titânio Quantec Series 2000 e Pow-R, valendo-se de quarenta instrumentos para cada marca divididos em oito para cada um dos seguintes tamanhos nº 15, nº 20, nº 25, nº 35 e nº 40 com 21 mm e conicidade .02. Com a ajuda de um troptômetro modificado cada instrumento foi fixado em um madril e preso à 3 mm de sua ponta, previamente marcada com uma caneta de tinta permanente, na base do aparelho por uma morsa. Em seguida ativou-se a manivela que continha a escala em graus até notar-se sinal característico da fratura do instrumento registrando-se o valor da quantidade de movimento até este momento. Após tabulação dos dados procedeu-se a análise estatística de acordo com o teste t de Student com nível de significância de 1%. Os resultados mostraram haver diferença estatisticamente significante ao comparar-se limas de mesmo número confrontadas as duas marcas, favorável para o instrumento Pow-R.The authors compared the torsional resistance between the Quantec Series 2000 and Pow-R nickel-titanium rotatory instruments, using forty instruments of each brand, divided in eight of each one of the following numbers: nº 15, nº 20, nº 25, nº 35 and nº 40 with 21 mm and taper .02. Each instrument was fixed in the mandrel of a modified tropometer and held 3 mm away from its tip, on a spot that had been previously stamped with a permanent ink pen, by apprehension claws localized on the base of the equipment. Then the graduated handle was activated until a characteristic break sign of the instrument was noticed, the quantity of movement up to this moment being recorded. After the values were tabulated, the statistical analysis was carried out according to the Student t test. The results revealed a statistically significant difference when instruments of the same number, from both evaluated brands, were compared, favouring the Pow-R instruments.

    Full Text Available Durante los 30 últimos años, los mercados financieros han registrado un enorme desarrollo. La introducción de los derivados financieros tales como opciones y futuros sobre subyacentes (títulos, obligaciones, monedas extranjeras, etc han conducido a una nueva cualidad de la seguridad de los riesgos financieros. La idea básica de un derivado financiero es comprar un seguro que cubra los activos arriesgados en el mercado, es decir, encontrar participantes en el mercado que traten de compartir los riesgos y los beneficios de los desarrollos futuros en el mercado en el que están sometidos a la incertidumbre. Una valoración de estos instrumentos financieros está basada en una teoría estadísticomatemática muy avanzada, llamada “Cálculo estocástico aplicado al campo financieroactuarial”. El modelo básico asociado a los precios de los títulos (valores, está expresado mediante el movimiento Browniano y ecuaciones diferenciales estocásticas. La valoración de una opción call Europea por Black, Scholes y Merton en 1973, fue un descubrimiento respecto a la comprensión y valoración de los derivados financieros. Su enfoque ha llegado a ser la base empresarial para las matemáticas financiero-actuariales modernas que utilizan instrumentos tales como la “teoría de martingalas” y “control estocástico” para obtener soluciones adecuadas en lo relativo a la valoración de un amplio campo del creciente número de derivados.

  12. Post-docking virtual screening of diverse binding pockets: comparative study using DOCK, AMMOS, X-Score and FRED scoring functions.

    Pencheva, Tania; Soumana, Oumarou Samna; Pajeva, Ilza; Miteva, Maria A

    2010-06-01

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

    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.

    Full Text Available Highly active antiretroviral therapy (HAART has been associated with dysglycaemia. However, there is scarce data on the risk of developing diabetes mellitus (DM in HIV/AIDS patients in Africa.Primarily to quantify and compare the risk of having diabetes mellitus in HIV/AIDS patients on HAART and HAART-naïve patients in Limbe, Cameroon; and secondarily to determine if there is an association between HAART and increased DM risk.A cross-sectional study was conducted at the Limbe Regional Hospital HIV treatment center between April and June 2013, involving 200 HIV/AIDS patients (100 on first-line HAART regimens for at least 12 months matched by age and gender to 100 HAART-naïve patients. The Diabetes Risk Score (DRS was calculated using a clinically validated model based on routinely recorded primary care parameters. A DRS ≥ 7% was considered as indicative of an increased risk of developing DM.The median DRS was significantly higher in patients on HAART (2.30% than in HAART-naïve patients (1.62%, p = 0.002. The prevalence of the increased DM risk (DRS ≥ 7% was significantly higher in patients on HAART, 31% (95% CI: 22.13-41.03 than in HAART-naïve patients, 17% (95% CI: 10.23-25.82, p = 0.020. HAART was significantly associated with an increased DM risk, the odds ratio of the HAART group compared to the HAART-naïve group was 2.19 (95% CI: 1.12-4.30, p = 0.020. However, no association was found after adjusting for BMI-defined overweight, hypertension, age, sex, family history of DM and smoking (Odds ratio = 1.22, 95% CI: 0.42-3.59, p = 0.708. Higher BMI and hypertension accounted for the increased risk of DM in patients on HAART. Also, more than 82% of the participants were receiving or had ever used Zidovudine based HAART regimens.HIV/AIDS patients on HAART could be at a greater risk of having DM than HAART-naïve patients as a result of the effect of HAART on risk factors of DM such as BMI and blood pressure.

    2008-01-01

    questionnaires were presented in part I; and, here in part II, one functional questionnaire and two sets of diagnostic criteria. Indices consist of organized forms for assigning scores to signs and symptoms thus obtaining severity degrees. Questionnaires are better employed for epidemiological purposes. Functional questionnaires are better used to assess impact of TMD on daily life activities. There are few specific sets of systematised diagnostic criteria available for diagnosing TMD. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD has been partially translated into Portuguese and had its accuracy and most psychometric properties validated, hence seems the best choice for assessing TMD.

    Introduction: The Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations instrument was developed to implement the conceptual framework of the Chronic Care Model in the Spanish national health system. It has been used to assess readiness to tackle chronicity in health care organisations. In this study, we use self-assessments at macro-, meso- and micro-management levels to (a) describe the two-year experience with the Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations tool in Spain and (b) assess the validity and reliability of this instrument. Methods: The results from 55 organisational self-assessments were included and described. In addition to that, the internal consistency, reliability and construct validity of Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations were examined using Cronbach's alpha, the Spearman–Brown coefficient and factorial analysis. Results: The obtained scores reflect opportunities for improvement in all dimensions of the instrument. Cronbach's alpha ranged between 0.90 and 0.95 and the Spearman–Brown coefficient ranged between 0.77 and 0.94. All 27 components converged in a second-order factorial solution that explained 53.8% of the total variance, with factorial saturations for the components of between 0.57 and 0.94. Conclusions: Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations is an instrument that allows health care organisations to perform self-assessments regarding their readiness to tackle chronicity and to identify areas for improvement in chronic care.

    Assessment of adolescents' dietary habits is challenging. Reliable instruments to monitor dietary trends are required to promote healthier behaviours in this group. The purpose of this cross-sectional study was to assess adolescents' adherence to Norwegian dietary recommendations with a diet score and to report results from, and test-retest reliability of, the score. The diet score involved seven food groups and one physical activity indicator, and was applied to answers from a semi-quantitative food frequency questionnaire (FFQ) administered twice. Reproducibility of the score was assessed with Cohen's Kappa (κ statistics) at an interval of three months. The setting was eight lower-secondary schools in Hordaland County, Norway, and subjects were adolescents (n = 472) aged 14-15 years and their caregivers. Results showed that the proportion of adolescents consistently classified by the diet score was 87.6% (κ = 0.465). For food groups, proportions ranged from 74.0% to 91.6% (κ = 0.249 to κ = 0.573). Less than 40% of the participants were found to adhere to recommendations for frequencies of eating fruits, vegetables, added sugar, and fish.

    2016-01-01

    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, tractio...

    Patients’ reports of their experience with illness are a key health outcome, but scores that measure these reports can be difficult to interpret. Skindex-29 measures skin-related quality of life reliably and validly. In this issue, Prinsen and colleagues compare patients’ responses to “anchor” questions with their Skindex scores to derive clinically meaningful scores for the subscales of Skindex-29. The cutoff scores identify patients whose skin diseases severely affect their quality of life....

    2013-02-01

    Full Text Available O trabalho analisa o impacto do uso de derivativos e a direção e magnitude do prêmio de cobertura relacionado a cada tipo de instrumento derivativo no valor da firma para uma amostra de empresas brasileiras não financeiras de capital aberto no período de 2004 a 2007. Os resultados indicam que a utilização de derivativos está relacionada a um impacto positivo e significativo sobre o valor de mercado das empresas. As evidências mostram que o uso de derivativos está associado a um “prêmio de cobertura” (hedging premium. Dessa maneira, é possível afirmar que as firmas que fazem uso da gestão de risco com derivativos têm um valor de mercado superior, no mercado brasileiro, quando comparadas a firmas que não utilizam esses instrumentos financeiros (hedging premium. Os resultados também indicam que, quando a análise se concentra no tipo de instrumento utilizado, a gestão de risco com tipos distintos de derivativos gera impacto de magnitude heterogênea no valor da firma. Contratos de swap e futuro/termo apresentam um impacto positivo e estatisticamente significante. Já para as opções, o impacto, embora positivo, não é estatisticamente significativo. Portanto, os resultados obtidos não só confirmam as expectativas de que a utilização de instrumentos derivativos exerce um impacto positivo e estatisticamente significativo sobre o valor da firma, mas também mostram que existe uma diferença relevante no efeito associado a derivativos distintos. Em conjunto, os resultados corroboram o fato de que investidores estão dispostos a pagar um maior valor por firmas que fazem gestão ativa de risco financeiro em ambientes mais voláteis como o Brasil, e essa disposição varia de acordo com o instrumento utilizado e com a eventual combinação de derivativos financeiros. Em pesquisa futura, uma análise das causas do impacto heterogêneo dos distintos instrumentos derivativos deve ser realizada para um melhor entendimento dos

  8. El comercio internacional un instrumento para alcanzar el desarrollo de Costa Rica

    2011-12-01

    Full Text Available El comercio internacional es un instrumento para la consecución del económico en los países subdesarrollados.  En Costa Rica las ventajas del libre comercio están asociadas a la generación de exportaciones, así como a la mayor producción y generación de nuevas oportunidades de empleo en comparación con las fuentes tradicionales.  No obstante, persisten desventajas asociadas al tamaño del país, la presencia de imperfecciones de mercado, las fuertes distorsiones causadas por la intervención estatal por la excesiva regulación, entre otras causas.  El propósito es explicar las ventajas y desventajas que tienen las empresas y los sectores productivos para competir en el comercio internacional y sugerir lineamientos estratégicos que fortalezcan la posición de las empresas en el mercado internacional.  Las dos principales interrogantes que orientan este trabajo son: ¿cuáles obstáculos enfrentan las empresas de países en desarrollo como Costa Rica para posicionarse exitosamente en los mercados internacionales?, y ¿cuál estrategia podría seguir Costa Rica para competir adecuadamente en esos mercados? La principal conclusión es que los tratados de libre comercio son instrumentos para la consecución del desarrollo económico y, por tanto, no es adecuado poner todos los esfuerzos en ellos como única fuente de superación de las múltiples necesidades sociales y económicas que experimentan las economías en desarrollo. Con seguridad, se requerirá formular políticas adicionales en el campo de la infraestructura, tecnología, salud, educación, entre otros, para posicionar mejor al país en los mercados internacionales.

    Full Text Available El presente trabajo expone la etapa inicial de un proyecto conjunto entre la Universidad Juárez Autónoma de Tabasco (UJAT y la Universidad Autónoma de Chiapas (UNACH, México; se trata de una estrategia diseñada para elaborar mecanismos que permitan a los programas virtuales autoevaluarse. La propuesta surge como resultado de la aplicación de un modelo de autoevaluación de programas a distancia diseñado por la Asociación Nacional de Universidades e Instituciones de Educación Superior (ANUIES y tomado como referencia para instrumentar en la UJAT, un ejercicio de autodiagnóstico durante el periodo 2008-2009. Los resultados mostraron la necesidad de pensar en mecanismos de evaluación situados en el contexto regional. La propuesta descansa, principalmente, en la revisión documental y en el panel de expertos elegidos mediante el método Delphi y Método combinado TZ. La estrategia metodológica consta de cuatro etapas: a revisión de modelos de evaluación; b la selección de expertos de dos universidades de los Estados de Tabasco y Chiapas que cuentan desde hace más de diez años con programas virtuales; c el diseño de instrumentos de auto diagnóstico y d la calificación de los instrumentos por los expertos. El reporte describe tres de las cuatro etapas del estudio. El promedio del índice de expertos en la autoevaluación fue similar en las dos universidades; se concluye, por lo tanto, que los expertos comparten un nivel de conocimiento afín, en especial en el diseño de materiales u objetos de aprendizaje, no así en indicadores de calidad estimados para la educación virtual.

    Full Text Available No Brasil, as ocorrências de gravidez na adolescência têm gerado discussões e preocupação no âmbito da saúde pública. Visto que a associação com o uso inadequado de métodos contraceptivos é direta, torna-se essencial avaliar o conhecimento de adolescentes sobre tais métodos para intervir adequadamente. Este estudo realizou este levantamento e avaliou a eficácia de um questionário construído para medir tal conhecimento de estudantes do nível médio de uma cidade do interior de São Paulo. Foi encontrada falta de conhecimento adequado sobre os métodos contraceptivos (como são, uso, eficácia, indicação, independente do sexo e do tipo de escola. O instrumento apresentou níveis psicométricos satisfatórios, adequado para ser disponibilizado e os dados obtidos por meio dele mostram-se confiáveis. Sua utilização enquanto recurso técnico de avaliação poderá servir como apoio para a elaboração de intervenções que almejem maior conhecimento sobre métodos contraceptivos, sexo seguro e menores taxas de gravidez na adolescência.

  18. Bioindicadores ambientais: insetos como um instrumento desta avaliação

    Marco Antonio de Oliveira

    2014-12-01

    Full Text Available Atividades agrícolas, florestais e do setor imobiliário vêm, ao longo do tempo, modificando ambientes ecologicamente estruturados. As consequências são drásticas e, por isso, faz-se necessária a busca por ferramentas e instrumentos para diagnosticar e monitorar a diversidade biológica desses locais. Os insetos têm-se destacado como potenciais organismos bioindicadores e isso se deve ao fato de apresentarem grande capacidade perceptiva, no que se refere a alterações do meio ambiente, principalmente por seu apurado sistema sensorial, que lhes permite qualificar condições ambientais em determinadas situações e, ainda, quantificar danos causados ao meio. Um dos problemas que podem ser associados a este setor é a falta de padronização e definição de protocolos de coleta e avaliação da biodiversidade, para que esses resultados possam ser analisados e extrapolados para diferentes ambientes antropizados. Neste trabalho, é contextualizada a importância da entomofauna como bioindicadora, em ecossistemas.

    2015-08-01

    Full Text Available El envejecimiento poblacional en los países desarrollados es una realidad que ha dado paso al aumento de las enfermedades degenerativas, entre ellas la demencia. Los cambios que se producen en la demencia, suponen una perdida funcional que vuelve a la persona afectada más dependiente de los demás para el desempeño de las actividades, por lo que estas pasan a ser una función asumida por el cuidador. El proceso de convertirse en cuidador supone la aparición, en muchos casos de sobrecarga, esto es, la percepción que el cuidador tiene acerca de la influencia que el cuidado tiene sobre su salud, su vida social, personal y económica. La cuantificación del riesgo de agotamiento, debería ser un procedimiento común. Por ello, este estudio pretende realizar una revisión de los instrumentos de evaluación de la sobrecarga del cuidador familiar de la persona con demencia. El método que se siguió fue la recisión sistemática de las bases de datos Lilacs, ProQuest, PsycARTICLES y Dialnet Plus, tras la cual, se pasó a buscar la fuente primaria de los instrumentos utilizados en los estudios hallados. Así, se encontraron 4 instrumentos distintos y 6 versiones de estos. En 34 de los 42 estudios, fue utilizado como instrumento de evaluación de la sobrecarga la escala de Zarit (Zarit Caregiver Burden Interview o una versión o adaptación del mismo. Estos resultados indican que la preferencia por esta escala para la evaluación de la sobrecarga en los cuidadores, es un continuo que no ha variado desde los años 90.

    Full Text Available En los últimos años se ha evidenciado que las actitudes hacia la organización o hacia la actividad en sí juegan un importante papel en la explicación de la continuidad de los voluntarios en las organizaciones. A pesar de ello, aún no se cuenta con instrumentos de evaluación adecuados que permitan un estudio más exhaustivo de estas actitudes en los voluntarios. En este artículo se presenta la adaptación a este ámbito de algunos instrumentos habitualmente utilizados para estudiar dichas actitudes en personal remunerado. El Organizational Commitment Questionarie (OCQ de Mowday, Steers y Porter, el Job Involvement de Lodahl y Kejner y el Job Diagnostic Survey de Hackman y Oldham adaptados a la población voluntaria se aplicaron a 419 voluntarios que realizaban muy diferentes actividades. El análisis de algunas de las propiedades psicométricas de estos instrumentos muestra que tanto el Organizational Commitment Questionarie como el Job Diagnostic Survey parecen adaptarse bien a las peculiaridades del voluntariado, en cambio, con el Job Involvement se encuentran resultados que permiten cuestionar su validez y adecuación, por lo que será necesario desarrollar más investigaciones para su rechazo o su afirmación definitiva en el estudio del voluntariado.

    Schomburg Dietmar

    2007-08-01

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

    The stratification score for a case-control study is the probability of disease modeled as a function of potential confounders. The authors show that the stratification score is a retrospective balancing score and thus plays a similar role in case-control studies as the propensity score plays in prospective studies. The authors further show how standardization using the stratification score can be used to compare the distributions of exposures that would be found among case and control partic...

    Sarzi-Puttini, Piercarlo; Fiorini, Tania; Panni, Benedetta; Turiel, Maurizio; Cazzola, Marco; Atzeni, Fabiola

    2002-01-01

    Background To analyse the relationship between subjective pain score and other measures of clinical, radiographic and functional status; in particular Larsen radiographic scores and Health Assessment Questionnaire (HAQ); in patients with severe rheumatoid arthritis (RA) with a disease duration of less than 3 years. Methods In this cross sectional study of 105 patients with RA (76 women, 29 men: mean age 50.93; mean disease duration 15.86 months; 71% rheumatoid factor positive) subjective pain was assessed according to the Visual Analog Scale (VAS). Correlation coefficients between pain score and disease activity measures (patients' global assessment of disease by VAS, number of tender and swollen joints, morning stiffness, erythrocyte sedimentation rate [ESR], C-reactive protein [CRP] and titre of rheumatoid factor, radiographic evaluations (Larsen-Dale scores for radiographic damage of the small joints of the hands, wrist and feet), disability measures (health assessment questionnaire [HAQ]), and demographic variables were calculated; hierarchical regression analysis was done with subjective pain score as the dependent variable. Results The Spearman's correlation coefficient comparing subjective pain and HAQ was 0.421 (p 0.05). In regression analysis, global assessment of disease by patients explained 32.8% of the variation in pain intensity score, morning stiffness 10.7%, CRP 4.0%, HAQ 3.8% and Larsen-Dale scores explained 2.1%; other variables were not significant in the model. Conclusions Pain scores of patients with early severe rheumatoid arthritis are correlated at higher levels with patients' global assessment of disease and with morning stiffness rather than with radiographic or other clinical variables such as number of tender and swollen joints.

  14. [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

  15. Random Walk Picture of Basketball Scoring

    Gabel, Alan

    2011-01-01

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

  16. Adjusting scoring matrices to correct overextended alignments

    Mills, Lauren J.; Pearson, William R.

    2013-01-01

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

  18. A Quantitative Theory of Credit Scoring

    Xuan Tam; Eric Young; Kartik Athreya

    2013-01-01

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

  19. Motivation, test scores and economic success

    Segal, Carmit

    2006-01-01

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

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

  1. Flexibilidade como Direcionador de Uso dos Instrumentos de Derivativos no Brasil

    Full Text Available Este trabalho buscou investigar a possível influência de fato- res na utlização dos instrumentos de derivativos. Em parti- cular, a pesquisa procurou analisar se percepções sobre sub- tipos de flexibilidade de produto (flexibilidade de cláusulas, flexibilidade de proteção, flexibilidade de estrutura e flexibili- dade de anonimato podem estar associados à freqüência de uso de derivativos. A partir de uma amostra de 102 profissi- onais da área financeira, respondentes de um questionário, foram realizadas análises para testar as hipóteses da pesquisa. Considerando a análise de regressão utilizada, apesar de os resultados não serem significativos do ponto de vista estatís- tico, sugerem que, com relação aos contratos de swaps, a flexibilidade das cláusulas é mais relevante na freqüência de uso. De maneira análoga, para os contratos a termo, a flexibi- lidade de proteção parece constituir fator mais relevante. Com relação aos contratos futuros, as flexibilidades de cláu- sula e de proteção surgem com coeficientes diferentes de zero na regressão dando indícios da influência destes sub-tipos de flexibilidade na freqüência de utilização do derivativo. Final- mente, para os contratos de opções, não se observou relacio- namento adequado entre sub-tipos de flexibilidade de pro- duto e o seu grau de utilização. Uma possível causa pode ser a complexidade destes instrumentos que torna menos freqüente sua utilização, mesmo tendo diversas características de flexibilidade. Dadas as limitações metodológicas do estu- do como, por exemplo, baixo número de observações na amostra e violações dos dados às premissas das técnicas estatísticas, os resultados não podem ser generalizados. Apesar das limitações, a pesquisa abordou o tema sob uma perspectiva, dentro da literatura sobre uso de derivativos, pouco explorada. Outros estudos comumente analisam o porte da empresa, o segmento de atuação, o nível de

  2. Scoring Function Based on Weighted Residue Network

    Shan Chang

    2011-12-01

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

    Zhong Guo ZHENG; Jing XU; Xing Wei TONG

    2006-01-01

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

  3. THE EFFICIENCY OF TENNIS DOUBLES SCORING SYSTEMS

    Geoff Pollard

    2010-09-01

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

  11. Steam sterilization of previously-assembled laparoscopic instruments Esterilización por vapor de los instrumentos laparoscópicos previamente armados Esterilização pelo vapor dos instrumentos laparoscópicos previamente montados

    Tamara Carolina de Camargo

    2008-01-01

    Full Text Available Video-laparoscopy represents one of the greatest surgical advances in the recent past. Reprocessable laparoscopic instruments are complex devices that, if completely disassembled for sterilization, would cause problems for the surgical teams at the moment of their use in the surgery. The method of choice for the sterilization of this equipment is saturated steam under pressure. The goal of this review was to describe the state-of-the-art in the search for safe results in autoclaving the previously-assembled reprocessable laparoscopic instruments, since they are difficult to assemble at the moment of surgery. The PUBMED database was consulted, using controlled and free keywords, as well as their combinations, without time or language restrictions. The study investigating the exact issue of this research found contamination in both assembled (1/24 and disassembled (1/30 instruments, demonstrating equivalent risks. In view of the results and considering the lack of studies, a new experimental laboratory study is recommended, using a contamination challenge.El video-laparoscopía representa uno de los mayores avances en el área de la cirugía en los últimos tiempos. Los instrumentos laparoscópicos reprocesables son artículos complejos, que si son esterilizados totalmente desarmados ocasionan trastornos a los equipos quirúrgicos en el momento de su utilización en el campo operatorio. El método de elección para la esterilización de esos instrumentos es el vapor saturado bajo presión. El objetivo de esta revisión fue describir el estado del arte en búsqueda de los resultados de la seguridad en el autoclavado del instrumental laparoscópico reprocesable, previamente armado, teniendo presente las dificultades de su montaje en el momento de la cirugía. Se consultó la base de datos PUBMED, usando vocablos controlados, libres y la combinación de ambos, sin restricción de tiempo e idioma. Fueron localizados apenas dos artículos que

    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...

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

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

    2011-08-01

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

La gestión de este nuevo objetivo lleva implícita la consideración simultánea de numerosa información de naturaleza económica, social y medioambiental. En los últimos años viene siendo práctica común la definición de un sistema de indicadores de sostenibilidad como principal instrumento de planificación. No obstante, la toma de decisiones de los agentes implicados en la planificación basada en la información proporcionada por dicho sistema no es una tarea sencilla. Para facilitar la utilización de la información contenida en este sistema por parte de los planificadores, los indicadores sintéticos constituyen un importante instrumento. En este contexto, en el presente trabajo se elaboran indicadores sintéticos de sostenibilidad para el caso del sector turístico español, centrando nuestro análisis en el caso de los destinos costeros. Para la obtención de estas medidas se aplican procedimientos de agregación alternativos basados en el Análisis de Componentes Principales y el indicador de distancia DP2.

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

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

  14. Trainee Occupational Therapists Scoring the Barthel ADL.

    Martin, Elizabeth; Nugent, Chris; Bond, Raymond; Martin, Suzanne

    2015-09-01

    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

  12. Disease severity scoring systems in dermatology

    Cemal Bilaç

    2016-06-01

    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.

Results Scores were assigned using four categories: the completeness of the assembly, the presence of full-length rRNA genes, tRNA composition and the presence of a set of 102 conserved genes in prokaryotes...

  14. Gambling scores for earthquake predictions and forecasts

    Zhuang, Jiancang

    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.

    2015-01-01

    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.

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

    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

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

    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.

MÉTODOS: Foram realizados testes de estabilidade e consistência interna. Para validação do Instrumento, os testes foram aplicados à amostra de 30 indivíduos com 60 anos ou mais, em dois momentos. A análise estatística foi realizada a partir de agrupamentos criteriosos de respostas, o que levou à formulação de uma versão simplificada do Instrumento. A estabilidade desta versão foi avaliada pelo coeficiente kappa e a consistência interna pelo coeficiente alpha de Cronbach. RESULTADOS: A estabilidade variou de moderada a excelente. A consistência interna foi verificada somente para áreas que se mostraram adequadas para o uso da metodologia baseada no cálculo do alpha de Cronbach: três das seis questões da área "perfil social" e os blocos das atividades básicas e instrumentais de vida diária da área "capacidade funcional", respectivamente com nove e oito atividades. CONCLUSÕES: Após os testes de estabilidade e consistência interna, o Instrumento possibilita classificação sucinta e simplificada de idosos quanto à capacidade funcional para atividades básicas e instrumentais e sua caracterização quanto aos demais aspectos do autocuidado. Evidências acerca de sua confiabilidade e validade podem ser ampliadas por meio de novos estudos.OBJECTIVE: To evaluate the reliability of an instrument for classifying elderly people regarding their capacity for self-care, which was developed to assist occupational therapists in attending elderly people at primary healthcare units.

  7. Perfiles de involucramiento del consumidor y el instrumento de medición para consumidores mexicanos "IP6"

    Jorge Vera Martínez

    2003-01-01

    Full Text Available Este escrito pretende esencialmente dos propósitos. En primer lugar se trata de presentar una visión general sobre el involucramiento del consumidor en el proceso de compra como una línea de investigación dentro de la mercadotecnia y el comportamiento de consumo. Además, se introduce al concepto del involucramiento en un sentido multifacético, al que se ha llamado “perfiles de involucramiento”, dependiente de diferentes factores que afectan a un consumidor cuando está en una situación de elección de compra; de igual forma se presenta una revisión de los diferentes modelos e instrumentos de medición que se han ofrecido para medir el involucramiento en este sentido multivariable. Son propuestas de operacionalización del involucramiento que se han diseñado en otros países y en idiomas distintos al español. El segundo objetivo, y más importante, radica en presentar los resultados sobre el diseño de un instrumento de medición basado en esta visión multifacética del involucramiento y en los inventarios desarrollados anteriormente en otros países; también se intenta ofrecer un instrumento que mida “los perfiles de involucramiento del consumidor en la elección de compra de un producto” en idioma español y aplicable en México. Para esto se diseñan, confiabilizan y validan (al menos de forma inicial una serie de reactivos en consumidores mexicanos que pretenden medir las distintas variables relacionadas con esta concepción del involucramiento. Este enfoque y su instrumento de medición pretende ser nombrado como el “IP6” (modelo de involucramiento de 6 perfiles. Asimismo, se obtienen 6 conjuntos de 3 reactivos cada uno con indicadores aceptables de confiabilidad y validez para medir cada perfil de involucramiento pretendido: “interés hacia el producto”, “placer percibido en su compra”, “valor simbólico que representa”, “importancia del riesgo al elegirlo”, “probabilidad percibida de ese riesgo” e

  10. La coordinación entre niveles asistenciales: una sistematización de sus instrumentos y medidas Coordination among healthcare levels: systematization of tools and measures

    Rebeca Terraza Núñez

    2006-12-01

    Full Text Available La mejora de la coordinación asistencial es una prioridad para muchos sistemas de salud y, especialmente, para la atención de problemas de salud crónicos en los que intervienen múltiples profesionales y servicios. La abundancia de estrategias y mecanismos de coordinación promovidos requiere una sistematización que ayude a utilizarlos de forma adecuada. El objetivo del artículo es analizar la coordinación asistencial y sus instrumentos, a partir de la teoría organizacional. Los mecanismos se pueden clasificar según el proceso básico utilizado para la coordinación de las actividades, programación o retroalimentación. La combinación óptima de mecanismos dependerá de 3 factores: grado de diferenciación de las actividades asistenciales, volumen y tipo de interdependencias y grado de incertidumbre. Históricamente, los servicios sanitarios han confiado la coordinación a la estandarización de las habilidades y, de manera más reciente, de los procesos mediante guías, mapas y planes. Su utilización resulta insuficiente para enfermedades crónicas en las que intervienen diversos profesionales con interdependencias recíprocas, variabilidad en la respuesta y un volumen de información procesada elevado. En este caso, son más efectivos los mecanismos basados en la retroalimentación, como grupos de trabajo, profesionales de enlace y sistemas de información vertical. La evaluación de la coordinación asistencial ha sido realizada hasta el momento de forma poco sistemática, mediante la utilización de indicadores de estructura, proceso y resultado. Las diversas estrategias e instrumentos se han aplicado, sobre todo, en los niveles sociosanitario y de salud mental; uno de los retos para la coordinación es extender y evaluar su uso a lo largo del continuo asistencial.Improving healthcare coordination is a priority in many healthcare systems, particularly in chronic health problems in which a number of professionals and services

    González de la Lastra, Leonor

    2011-06-01

    Full Text Available This paper presents the results of the labours undertaken in the Instituto San Isidro regarding the conservation, documentation and contextualization of the XIXth century scientific instruments that still belong to this institution. In order to achieve an historical understanding of the collection, the attention is focused on the political and educational decisions taken by the Spanish authorities in the period considered. Besides, particular attention is paid to technological pieces, which in general were used, as in other countries, to illustrate the “applied side” of physics.

    En el presente artículo se tratan las tareas de recuperación y documentación del material científico antiguo existente en el actual instituto San Isidro de Madrid tras el traslado en 1985 de una parte importante al Museo Nacional de Ciencia y Tecnología. Para contextualizar dicha colección, destinada en su mayoría a la enseñanza de la Física en el s. XIX, se estudia su creación y desarrollo, relacionándolos con la historia del centro, así como con los acontecimientos políticos y educativos que condicionaron sus características. Asimismo, se señala la presencia en esta colección de instrumentos tecnológicos, tema insuficientemente tratado en los trabajos disponibles, vinculados a las enseñanzas de Física. A la hora de describir las tareas destinadas a recuperar los instrumentos científicos mencionados se describe tanto la metodología seguida como los resultados, ejemplificados en la documentación de dos piezas representativas, una de Física y otra de carácter tecnológico.

    Ana Isabel Muñoz Mazón

    2012-01-01

    Full Text Available Se da un tácito consenso asumiendo que la actividad turística es un instrumento efi caz y efi ciente de desarrollo económico y social. Sin embargo, a pesar de las frecuentes declaraciones de índole política a tal respecto, es notoria la falta de un marco teórico-práctico de turismo para el desarrollo. Muchas cuestiones clave necesitan un análisis más profundo: (i qué entendemos como desarrollo a estos efectos; (ii cuál es la contribución del turismo a ese desarrollo; y (iii qué formulación y alcance deben tener las políticas turísticas y su gobernanza para que el turismo sea realmente un instrumento de desarrollo. En este artículo se expone un breve análisis-respuesta a estas cuestiones. A la vista de los paradigmas de desarrollo de las últimas décadas (modernización, neoliberalismo, dependencia, y sostenibilidad, se consideran propuestas apoyadas en la Nueva Economía Institucional y la Teoría del Capital Social, y posibles contenidos de la política y gobernanza del turismo vis-à-vis el desarrollo. Se presentan también a este respecto los resultados de la consulta, realizada en 2011, a 60 expertos de 15 países, en los ámbitos académico, profesional y político.

  14. Direito Internacional Privado: o diálogo como instrumento de efetivação dos Direitos Humanos

    Gisele Cittadino

    2012-07-01

    Full Text Available The Private international law, having as the axiological axis the man, is one of the most important tools of legal science in the recognition and preservation of dignity and human rights. The intercultural dialogue, in turn, is an instrument used by private international law as a way to find a common denominator between the rights of different peoples from different cultures. The standardization and codification of Private International Law, through the composition of large spaces of debate and negotiation, as the Permanent Convention Hague, allow respect for cultural and social differences. Consequently, during the construction of the best law to be applied or even the substantive law adopted by the Convention, it’s built a solid and legitimate set of rules that provides promotion to the individual.Resumo: O Direito Internacional Privado, tendo como eixo axiológico o homem, é um dos mais importantes instrumentos da ciência jurídica no reconhecimento e preservação da dignidade e dos direitos humanos. O dialogo intercultural, por sua vez, é instrumento utilizado pelo Direito Internacional Privado como forma de encontrar um denominador comum entre os direitos dos mais diversos povos das mais diversas culturas. A uniformização e a codificação do Direito Internacional Privado, por meio da composição de grandes ambientes de debates e negociação, como a Convenção Permanente da Haia, possibilitam o respeito às diferenças culturais e sociais. Consequentemente, no momento da construção da melhor lei a ser aplicada ou até mesmo da lei material adotada pela Convenção, constrói-se um conjunto normativo sólido e legítimo que fornece ao indivíduo sua promoção.

    Porto Currás, Mónica

    2013-04-01

    Full Text Available The instruments used for information gathering provide the information to assess whether students have achieved the competences set out in the training plan. Therefore, knowing how they understand and describe the capabilities and skills they are demonstrating is useful information to be considered at times of change and curriculum restructuring. In this paper we describe the results of study in which students describe what is involved in each of the assessment techniques they have undergone during their undergraduate studies and what skills were used in each case. With this information, we have tried to organise the types of tools to collect information with skills developed from the perceptions of students, presenting a continuum of cognitive abilities.Los instrumentos empleados para la recogida de información aportan la información para evaluar si se han logrado las competencias previstas en un plan formativo. Por ello, conocer cómo entienden y describen los estudiantes las capacidades y destrezas que están demostrando en ellos, es una información a tener en cuenta en momentos de cambio y reestructuraciones de los planes de estudio. En este artículo mostramos los resultados obtenidos en una investigación, en la que los estudiantes describen qué implica cada una de las técnicas de evaluación que han realizado a lo largo de sus estudios de licenciatura y qué destrezas debían emplear en cada una de ellas. Con la información recogida, hemos intentado organizar las tipologías de instrumentos de recogida de información con las capacidades desarrolladas desde las percepciones de los estudiantes, presentando un continuo de habilidades cognitivas.

  17. Interpreting the Meaning of Pain Severity Scores

    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.

    2014-04-01

    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

    Purpose:.Open globe eye injuries can have profound social and economic consequences. Here, we describe two cases of war and outdoor activity open globe eye injury where, despite a low OTS score,.current microsurgical technology allowed for a favorable outcome.Case report 1: A 33-year-old Libyan soldier had been treated for an open-globe grenade blast trauma to his left eye, which showed light perception and OTS score 2..He had undergone a lensectomy and PPV with silicone oil tamponade. Surgical treatment included scleral buckling,.cornea trephination, tem-porary Eckardt keratoprosthesis, PPV revision, intraocular lens (IOL) implantation, and corneal grafting. Six months later, his VA was improved to 20 / 70.Case report 2:.A 35-year-old man presented with a corneal laceration in his left eye from a meat skewer,.with marked hypotony and LP..After primary corneal wound closure,.B-scan ultrasonography revealed massive vitreous hemorrhage (OTS score 2). The patient underwent open cataract extraction with IOL implantation, 23 gauge PPV, laser photocoagulation of the retinochoroidal laceration, and a gas tamponade. After three weeks,.the patient underwent a 2nd 23G PPV due to a fibrinous reaction. Six month later, the patients exhibited 20 /25 VA.Conclusion:.These cases confirm that even for patients with a low OTS and poor visual prognosis,.an up-to-date surgery protocol may achieve visual results adequate for leading an autonomous daily life.

    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

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.

    2015-07-01

    The Tunka-HiSCORE detector is a non-imaging wide-angle EAS cherenkov array designed as an alternative technology for gamma-ray physics above 10 TeV and to study spectrum and composition of cosmic rays above 100 TeV. An engineering array with nine stations (HiS-9) has been deployed in October 2013 on the site of the Tunka experiment in Russia. In November 2014, 20 more HiSCORE stations have been installed, covering a total array area of 0.24 square-km. We describe the detector setup, the role of precision time measurement, and give results from the innovative WhiteRabbit time synchronization technology. Results of air shower reconstruction are presented and compared with MC simulations, for both the HiS-9 and the HiS-29 detector arrays.

    2010-11-01

    Full Text Available A introdução do Programa Saúde da Família foi uma tentativa de reorganizar a atenção básica no país, que instituiu a Visita Domiciliar, como instrumento diferencial da atuação do Médico de Família. Para estabelecer prioridades na visita, elaborou-se escala de risco familiar baseada na ficha A do SIAB. Tal escala se baseia em sentinelas de risco que são avaliadas na primeira visita domiciliar pelo agente de saúde (ACS. A mesma foi aplicada em diferentes comunidades e microáreas, demonstrando diversas proporções de famílias classificadas como risco 1, 2 ou 3. Os resultados ressaltam a relação morador/cômodo como um importante indicador na avaliação do risco, bem como a aplicabilidade da escala como instrumento de priorização tanto das visitas domiciliares quanto do investimento da equipe. A escala demonstrou ser um instrumento simples e eficiente de análise do risco familiar, não necessitando a criação de nenhuma nova ficha ou escala burocrática. Os autores sugerem que somente o uso sistemático da Escala de Coelho como instrumento de reorganização da demanda, e posterior avaliação de seu impacto na comunidade, poderá confirmar sua aplicabilidade na atuação do médico de família.The introduction of the Health Family Program was an attempt to reorganize the primary care in Brazil, presenting the House Visiting as an instrument peculiar to the Family Physician's activity.

  19. Balancing Covariates via Propensity Score Weighting

    Li, Fan; Morgan, Kari Lock; Zaslavsky, Alan M.

    2014-01-01

    Covariate balance is crucial for an unconfounded descriptive or causal comparison. However, lack of balance is common in observational studies. This article considers weighting strategies for balancing covariates. We define a general class of weights-the balancing weights-that balance the weighted distributions of the covariates between treatment groups. These weights incorporate the propensity score to weight each group to an analyst-selected target population. This class unifies existing we...

  20. When Can School Inputs Improve Test Scores?

    Stefan Dercon

    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...

  3. A Social Approach to Microfinance Credit Scoring

    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. MODELING CREDIT RISK THROUGH CREDIT SCORING

    Adrian Cantemir CALIN; Oana Cristina POPOVICI

    2014-01-01

    Credit risk governs all financial transactions and it is defined as the risk of suffering a loss due to certain shifts in the credit quality of a counterpart. Credit risk literature gravitates around two main modeling approaches: the structural approach and the reduced form approach. In addition to these perspectives, credit risk assessment has been conducted through a series of techniques such as credit scoring models, which form the traditional approach. This paper examines the evolution of...

    2013-02-01

    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.

    We develop new tools for formal inference and informal model validation in the analysis of spatial point pattern data. The score test is generalized to a "pseudo-score" test derived from Besag's pseudo-likelihood, and to a class of diagnostics based on point process residuals. The results lend theoretical support to the established practice of using functional summary statistics, such as Ripley's $K$-function, when testing for complete spatial randomness; and they provide new tools such as th...

  12. On Interpreting Test Scores as Social Indicators: Statistical Considerations.

    Spencer, Bruce D.

    1983-01-01

    Because test scores are ordinal not cordinal attributes, the average test score often is a misleading way to summarize the scores of a group of individuals. Similarly, correlation coefficients may be misleading summary measures of association between test scores. Proper, readily interpretable, summary statistics are developed from a theory of…

    Alhan, C; Westers, T M; Cremers, E M P; Cali, C; Witte, B I; Ossenkoppele, G J; van de Loosdrecht, A A

    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

  2. Evaluating the Validity and Applicability of Automated Essay Scoring in Two Massive Open Online Courses

    Erin Dawna Reilly

    2014-11-01

    Full Text Available The use of massive open online courses (MOOCs to expand students’ access to higher education has raised questions regarding the extent to which this course model can provide and assess authentic, higher level student learning. In response to this need, MOOC platforms have begun utilizing automated essay scoring (AES systems that allow students to engage in critical writing and free-response activities. However, there is a lack of research investigating the validity of such systems in MOOCs. This research examined the effectiveness of an AES tool to score writing assignments in two MOOCs. Results indicated that some significant differences existed between Instructor grading, AES-Holistic scores, and AES-Rubric Total scores within two MOOC courses. However, use of the AES system may still be useful given instructors’ assessment needs and intent. Findings from this research have implications for instructional technology administrators, educational designers, and instructors implementing AES learning activities in MOOC courses.

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

    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.

    Full Text Available BACKGROUND: We explore the association between bone T-scores, used in osteoporosis diagnosis, and functional status since we hypothesized that bone health can impact elderly functional status and indirectly independence. METHODS: In a cross-sectional study (2005-2006 on community dwelling elderly (> = 75 years from Herne, Germany we measured bone T-scores with Dual-energy X-ray Absorptiometry, and functional status indexed by five geriatric tests: activities of daily living, instrumental activities of daily living, test of dementia, geriatric depression score and the timed-up-and-go test, and two pooled indexes: raw and standardized. Generalized linear regression was used to determine the relationship between T-scores and functional status. RESULTS: From 3243 addresses, only 632 (19% completed a clinical visit, of which only 440 (male:female, 243:197 could be included in analysis. T-scores (-0.99, 95% confidence interval [CI], -1.1-0.9 predicted activities of daily living (95.3 CI, 94.5-96.2, instrumental activities of daily living (7.3 CI, 94.5-96.2, and timed-up-and-go test (10.7 CI, 10.0-11.3 (P < = 0.05. Pooled data showed that a unit improvement in T-score improved standardized pooled functional status (15 CI, 14.7-15.3 by 0.41 and the raw (99.4 CI, 97.8-101.0 by 2.27 units. These results were limited due to pooling of different scoring directions, selection bias, and a need to follow-up with evidence testing. CONCLUSIONS: T-scores associated with lower functional status in community-dwelling elderly. Regular screening of osteoporosis as a preventive strategy might help maintain life quality with aging.

    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.

    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

    Full Text Available O transtorno de ansiedade social (TAS é um distúrbio de difícil diagnóstico pelos clínicos, o que estimula o estudo e desenvolvimento de instrumentos que favoreçam seu reconhecimento precoce e sistemático. Objetiva-se identificar na literatura indexada entre janeiro de 1999 e julho de 2004, artigos relativos a estudos psicométricos sobre instrumentos para avaliação do TAS. Procedeu-se à busca sistemática nos indexadores PsycoInfo, Lilacs e Medline, utilizando-se as palavras-chaves: social phobia scale, social phobia validity, social phobia reliability e social anxiety, identificando-se 26 artigos. Para a análise, os estudos foram agrupados em dois conjuntos: a onze relativos à Liebowitz Social Anxiety Scale (LSAS, e b quinze relativos a outras escalas já validadas ou em validação. Dos estudos com a LSAS, seis trabalharam com a versão hetero-aplicada e quatro com a auto-aplicada, tendo identificado qualidades psicométricas satisfatórias quanto à validade no idioma original (inglês, e outros idiomas: francês, hebraico, turco e espanhol. Do mesmo modo, bons índices de fidedignidade foram encontrados e quanto à análise fatorial, o modelo de quatro fatores foi considerado o mais adequado. Dos estudos com outras escalas, sete trabalharam com instrumentos já validados e oito com novas escalas, identificando valores satisfatórios quanto à validade e fidedignidade. As principais limitações verificadas nos estudos relacionaram-se à diversidade de padrão-ouro adotada, composição amostral com ausência de claros critérios de inclusão e exclusão, e pequeno número de estudos com amostras não-clínicas, dificultando o uso dos instrumentos para rastreamento na população geral Estudos futuros que visem aprimorar a validação de critério com base na análise fatorial e de cluster, parecem necessários e oportunos.Social anxiety disorder (SAD is difficult to diagnose by clinicians, a fact that stimulates the study and

    Full Text Available Disponer de suelo urbanizable es requisito indispensable para cumplir el propósito de brindar viviendas a la población, pero, el acceso a este suelo enfrenta obstáculos de tipo técnico, administrativo y normativo, que generan procesos caóticos de urbanización en las principales ciudades del país. En este artículo se analizan los instrumentos de gestión de suelo disponibles y utilizados en proyectos desarrollados por Metrovivienda en la localidad de Bosa en Bogotá D.C. Como resultado, se encuentra que las principales causas son: la escasez y los altos precios del suelo urbanizable y la persistencia del fenómeno de urbanización ilegal que pretende cubrir la demanda insatisfecha, especialmente para población no vinculada al mercado laboral formal. La Política Pública de Vivienda se enfoca principalmente en la asignación de subsidios a la demanda y la implementación de proyectos de construcción, pero, sin una Política Pública de Suelo que regule el uso y mercado, no se podrá planear a largo plazo y será muy difícil disminuir la brecha entre la oferta y la demanda de viviendas y lograr un desarrollo eficiente, equitativo y ordenado de la ciudad.

  6. Gender, Stereotype Threat and Mathematics Test Scores

    Ming Tsui

    2011-01-01

    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.

  13. Determining utility values in patients with anterior cruciate ligament tears using clinical scoring systems

    Szucs Thomas

    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.

  14. 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 Liver biopsy is indispensable because liver stiffness measurement alone cannot provide information on intrahepatic inflammation. However, the presence of fibrosis highly correlates with inflammation. We constructed a noninvasive model to determine significant inflammation in chronic hepatitis B patients by using liver stiffness measurement and serum markers.The training set included chronic hepatitis B patients (n = 327, and the validation set included 106 patients; liver biopsies were performed, liver histology was scored, and serum markers were investigated. All patients underwent liver stiffness measurement.An inflammation activity scoring system for significant inflammation was constructed. In the training set, the area under the curve, sensitivity, and specificity of the fibrosis-based activity score were 0.964, 91.9%, and 90.8% in the HBeAg(+ patients and 0.978, 85.0%, and 94.0% in the HBeAg(- patients, respectively. In the validation set, the area under the curve, sensitivity, and specificity of the fibrosis-based activity score were 0.971, 90.5%, and 92.5% in the HBeAg(+ patients and 0.977, 95.2%, and 95.8% in the HBeAg(- patients. The liver stiffness measurement-based activity score was comparable to that of the fibrosis-based activity score in both HBeAg(+ and HBeAg(- patients for recognizing significant inflammation (G ≥3.Significant inflammation can be accurately predicted by this novel method. The liver stiffness measurement-based scoring system can be used without the aid of computers and provides a noninvasive alternative for the prediction of chronic hepatitis B-related significant inflammation.

    Full Text Available RESUMEN Actualmente, los procesos de planificación turística están orientados para que sean los agentes locales quienes formulen las actuaciones necesarias en cada destino. Sin embargo, en la práctica estos agentes no cuentan con la información suficiente para realizar esta tarea. Necesitan de herramientas que les permitan evaluar el actual grado de sostenibilidad de la actividad turística y determinar las medidas necesarias para mejorarlo. En este trabajo proponemos como instrumento de medición un sistema de indicadores de turismo sostenible. Para facilitar el uso de la información del mismo, obtenemos indicadores sintéticos que proporcionan una visión de conjunto mediante un procedimiento que combina el Análisis en Componentes Principales y la distancia a un punto de referencia, de forma que el indicador sintético obtenido, que denominamos DCP, tenga una menor subjetividad asociada. Finalmente, analizamos la sostenibilidad de los destinos costeros en Andalucía para ilustrar la forma en la que se aplica la metodología propuesta y se interpretan los resultados obtenidos.ABSTRACT Nowadays, local agents formulate the necessary public measures in the processes of tourism planning of each destination. However, in the practice these agents do not have enough information to carry out this task. They need tools to assess the current level of sustainability of tourism activity and identify the necessary measures to improve it. In this paper we propose a system of sustainable tourism indicators as a measuring tool. In order to facilitate the use of information system, we also develop synthetic indicators that provide an overview. They are obtained with a methodology that combines Principal Components Analysis and the distance to a reference point, so that this synthetic indicator, called DCP indicator, have a smaller associate subjectivity. Finally, we apply the proposed methodology to Andalusian coastal destinations and we illustrate how

  6. Scoring functions--the first 100 years.

    Tame, Jeremy R H

    2005-06-01

    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

  8. Reproducibility of scoring emphysema by HRCT

    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

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....

Esse instrumento foi desenvolvido para permitir uma rápida mensuração dos estados de humor entre populações de adolescentes e adultos, já tendo sido demonstrada, em recentes pesquisas, sua eficácia no diagnóstico desses estados alterados pelo treinamento intensivo. O POMS-A foi administrado a atletas adultos de competição, atletas estudantes adultos, atletas adolescentes de competição e estudantes adolescentes. Um subgrupo de atletas estudantes adultos foi utilizado para testar a validade do critério do POMS-A. A análise do fator confirmatório deu suporte para a validade fatorial do modelo de 24 itens e seis fatores, usando ambas as análises: independente e amostras múltiplas. Relações entre os escores do POMS-A e medidas validadas previamente, que eram coerentes com fundamentações teóricas, sustentaram a validade do critério de medida. Evidências foram encontradas dando suporte à integridade psicométrica do POMS-A quando se estendeu de adolescentes para populações de adultos. Tais evidências sugerem que o POMS-A é um instrumento apropriado para avaliação de perfis do humor, além do que a brevidade do teste facilita a coleta de dados em ambientes de pesquisa.

  14. Coronary artery calcium scoring in myocardial infarction

    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)

  15. DLQI and POSAS Scores in Keloid Patients.

    Poetschke, Julian; Reinholz, Markus; Schwaiger, Hannah; Epple, Andreas; Gauglitz, Gerd G

    2016-06-01

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

    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

  18. 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.
