Guía programática para el desarrollo de la asignatura derecho laboral, en la carrera de Licenciatura en Contaduría Pública de la Universidad de El Salvador, Facultad Multidisciplinaria Oriental, año 2016

Diseñar una Guía Programática de Derecho Laboral que contribuya al proceso de enseñanza - aprendizaje de los estudiantes de Contaduría Pública de la Facultad Multidisciplinaria Oriental. Para poder tener una idea clara sobre el método de investigación, primero se debe saber en qué consiste, por ello, se entenderá por método de investigación a la manera de alcanzar un objetivo; o bien se le define como determinado procedimiento para ordenar la actividad; es el camino que se sigue en la investigación. Este ayudará a abordar o enfocar un problema, recopilar la información, analizarla y presentarla. Finalmente, se identificó que al inicio del ciclo académico al desarrollar la asignatura de Derecho Laboral les fue proporcionado a los estudiantes el Programa de Estudio, indicando la responsabilidad por parte del docente para dárselos a conocer y de esta forma los estudiantes verificar el desarrollo de todos los contenidos a lo largo del curso de la materia. Y también se comprobó que existe la necesidad de actualizar el Programa de estudio de Derecho Laboral mediante una Guía Programática que facilite el proceso de enseñanza aprendizaje de los estudiantes de Contaduría Pública, así como la necesidad de que se incorporen nuevos temas en el desarrollo de la asignatura acordes a la actualidad para el Contador Público en el campo del Derecho Labora

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Precision measurement of the structure of the CMS inner tracking system using nuclear interactions

The structure of the CMS inner tracking system has been studied using nuclear interactions of hadrons striking its material. Data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are used to reconstruct millions of secondary vertices from these nuclear interactions. Precise positions of the beam pipe and the inner tracking system elements, such as the pixel detector support tube, and barrel pixel detector inner shield and support rails, are determined using these vertices. These measurements are important for detector simulations, detector upgrades, and to identify any changes in the positions of inactive elements

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
