Esta investigación procuró determinar la relación que existe entre las variables autoeficacia docente y autoestima de 86 profesores que laboran en colegios adventistas de los Llanos Orientales, Colombia. Además de responder a preguntas sociodemográficas, los docentes complementaron la (a) Escala del Sentido de Eficacia Docente, compuesta de 24 ítems, y el (b) Test de Autoestima en Profesores, que consta de 72 ítems. Se encontró́ correlación significativa entre las puntuaciones totales de las variables autoeficacia docente y autoestima de profesores. Las relaciones positivas significativas se observaron entre la variable autoestima del profesor y dos subescalas de la variable autoeficacia docente (instrucción y gestión) y entre la variable autoeficacia docente y dos subescalas de la variable autoestima de profesores (identidad y comportamiento). También se observó que algunas variables demográficas ─edad, años de experiencia docente, escolaridad, género y estado civil─ presentan efectos sobre las variables del estudio y sobre algunas subescalas y correlaciones entre los constructos.

Abstract Background Influenza places a significant burden on global health and economics. Individual case management and public health efforts to mitigate the spread of influenza are both strongly impacted by our ability to accurately and efficiently detect influenza viruses in clinical samples. Therefore, it is important to understand the performance characteristics of available assays to detect influenza in a variety of settings. We provide the first report of relative performance between two products marketed to streamline detection of influenza virus in the context of a highly controlled volunteer influenza challenge study. Methods Nasopharyngeal swab samples were collected during a controlled A/California/2009/H1N1 influenza challenge study and analyzed for detection of virus shedding using a validated qRT-PCR (qPCR) assay, a sample-to-answer qRT-PCR device (BioMerieux BioFire FilmArray RP), and an immunoassay based rapid test kit (Quidel QuickVue Influenza A + B Test). Results Relative to qPCR, the sensitivity and specificity of the BioFire assay was 72.1% [63.7–79.5%, 95% confidence interval (CI)] and 93.5% (89.3–96.4%, 95% CI) respectively. For the QuickVue rapid test the sensitivity was 8.5% (4.8–13.7%, 95% CI) and specificity was 99.2% (95.6–100%, 95% CI). Conclusion Relative to qPCR, the BioFire assay had superior performance compared to rapid test in the context of a controlled influenza challenge study.

AbstractThe pursuit of audience attention online has led organizations to conduct thousands of behavioral experiments each year in media, politics, activism, and digital technology. One pioneer of A/B tests was Upworthy.com, a U.S. media publisher that conducted a randomized trial for every article they published. Each experiment tested variations in a headline and image “package,” recording how many randomly-assigned viewers selected each variation. While none of these tests were designed to answer scientific questions, scientists can advance knowledge by meta-analyzing and data-mining the tens of thousands of experiments Upworthy conducted. This archive records the stimuli and outcome for every A/B test fielded by Upworthy between January 24, 2013 and April 30, 2015. In total, the archive includes 32,487 experiments, 150,817 experiment arms, and 538,272,878 participant assignments. The open access dataset is organized to support exploratory and confirmatory research, as well as meta-scientific research on ways that scientists make use of the archive.

ObjectiveThe early and efficacious detection of neurocognitive disorders poses a key diagnostic challenge. We examined how nine bedside cognitive tests perform across the spectrum of delirium and motor subtypes.MethodsThe performance on a battery of nine bedside cognitive tests were compared in elderly medical inpatients with DSM-IV delirium, subsyndromal delirium, and no neurocognitive disorder and in different motor subtypes of patients with delirium.ResultsOne hundred and ninety-eight patients (mean age 79.14 ± 8.26) were assessed with no delirium (n = 43), subsyndromal delirium (n = 45), and full syndromal delirium (n = 110). The ability to meaningfully engage with the tests varied from 59% for vigilance B test to 85% for Spatial Span forward test and was found to be least in the full syndromal delirium group. The no delirium group was distinguished from the delirium groups for all the tests and from the full syndromal delirium group for the vigilance B test and global visuospatial function test. The subsyndromal delirium group differed from the full syndromal delirium group in respect of global visuospatial function test, spatial span backwards and vigilance A tests. Patients with full syndromal delirium were best identified using the interlocking pentagons test and clock drawing test. The ability to engage with testing was higher for those in the no subtype group.ConclusionsSimple bedside tests of attention, vigilance, and visuospatial ability are useful to help to distinguish neurocognitive disorders namely subsyndromal delirium from other presentations.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

This research aimed to develop a physics problem-solving skill (PSS) test for grade X students of senior high school which met test instrument characteristics and feasibility. The development stages included: (a) test designing, (b) test trial, and (c) test revision and preparation. The designing stage included: (1) needs analysis, (2) mapping, (3) drawing conclusion, (4) determining test purpose, (5) determining competencies, (6) determining materials, (7) preparing answers, (8) writing items, (9) validating content, (10) improving and preparing the test, and (11) preparing the scoring guide with PCM. The trial stage consisted of: (1) determining trial subjects, (2) performing trial, and (3) analyzing trial result data based on IRT. The study was performed in Kulonprogo involving 281 students. The result shows that the instrument fulfills content validity with Aiken’s V of 0.95 to 0.98. Based on INFIT MNSQ criteria, 52 items fit PCM, item difficulty index ranges from -1.47 to 0.88, meaning that all items are good, and information function analysis and SEM show that the test  fits the ability between -1.3 and 2.7. Therefore, the test instrument meets the characteristics and feasibility to measure physics PSS in high school.
