Congruencia entre los valores personales y organizacionales y su influencia con el engagement en el trabajo : estudio de caso en una organización del sector salud

La capacidad de gestión del personal se ha convertido en un imperativo para las organizaciones modernas. Por tanto se vienen introduciendo temas como la administración en valores y el engagement de los trabajadores. Sin embargo, la relación entre estos dos aún no ha sido estudiada. El presente estudio tiene como objetivo analizar el efecto que tiene el grado de articulación y reconocimiento de los valores organizacionales y personales y organizacionales sobre los niveles de engagement de los empleados. Para esta investigación se utilizó una muestra constituida por 54 trabajadores de una organización del sector salud de la ciudad de Bogotá a quienes les fueron aplicadas dos escalas: el Inventario para Medir la Articulación entre la Persona y la Organización (Inventario APO) y Utrech Work Engagement Scale (UWES). Como principal resultado se obtuvo que de las tres dimensiones consideradas predictoras del engagement, solamente el reconocimiento de los valores organizacionales tuvo un efecto estadísticamente significativo.

Inequidad y posición socioeconómica en la reproducción de la actividad física en entornos educativos. Análisis conceptual.

Objetivo: analizar cómo influye la inequidad y la posición socio económica como factores determinantes de la conceptualización de la actividad física, desde la concepción de los determinantes sociales, de forma tal que su revisión conceptual, ayude a constituir la re configuración del concepto de actividad física. Métodos: Exploración de la literatura científica desde la revisión conceptual de artículos seleccionados, utilizando las categorías inequidad y posición socioeconómica para establecer la influencia del concepto de la actividad física en entornos educativos. Y a partir de ella interpretar la re configuración del concepto de la actividad física, desde diferentes concepciones asociadas a los determinantes sociales. Resultados: Se hallaron concepciones de los diferentes autores respecto al concepto de la actividad física. (Peso, raza, índice de masa corporal, edad). Se interpretaron distintos niveles de influencia desde la inequidad y la posición socio económica asociados a la ocupación, el género, sitio de vivienda, nivel de estudio, y la estructura física del entorno. Posteriormente se reportaron resultados desde un análisis explicativo en el cual se interpretan las concepciones de los autores en cuanto al concepto de la actividad física, y como desde ella se establecen relaciones entre la inequidad, la posición socioeconómica y los entornos educativos que incluyen diferentes aspectos sociales para finalmente poder establecer un concepto claro de la re configuración social del concepto de la actividad física, concluyendo que este nuevo concepto social de la actividad física no posee una definición exacta, el análisis de los aspectos sociales de ésta, involucra innumerables concepciones que la influencian y la determinan, en consecuencia el concepto de la actividad física debe ser un concepto en constante evolución y reconfiguración debido a la naturaleza cambiante del ser humano, de las dinámicas sociales y las asociaciones de la salud con los aspectos sociales que se presentan en el diario vivir. Así mismo se evidencia que el concepto de la actividad física se fundamenta en estudios que dejan de lado los aspectos sociales que influencia el concepto y en consecuencia la práctica de la actividad física, esta investigación establece un punto de partida frente a la re configuración social del concepto de la actividad física. Conclusiones: Diferentes organizaciones en el mundo reconocen a la actividad física como una herramienta que favorece la socialización de las personas. Es así como la actividad física, desde el deporte en el campo competitivo y la educación física desde el campo educativo exploran la interacción social de los individuos, esto permite la construcción de valores y fortalece la sana convivencia dentro de las comunidades. Esta trasformación desde el concepto de la actividad física biomédica hasta la actividad física social se evidencia en los documentos revisados, en los cuales la actividad física es estudiada desde las categorías de inequidad y posición socio económica, De ahí que en su conceptualización se involucren diferentes conceptos asociados a los determinantes sociales de la salud, que en definitiva establecen un nuevo concepto de la re configuración social de la actividad física trascendiendo desde la actividad física biomédica o fisiológica hasta un concepto complejo que incluye intereses y particularidades de las personas como lo son la ocupación, la educación, el entorno, el medio ambiente y la estructura física.

Da dominação à cooperação: a paz perpétua e a luta eterna entre nações

O presente ensaio tem por objetivo a construção de uma linha de pensamento sobre as teorias e a realidade das Relações Internacionais baseada na pluralidade de valores e na justaposição de ideias que designam e afetam as relações entre os atores internacionais, assim como, entender os reflexos que estes fatores têm nos desfechos destas interações resultantes em cooperação e conflito. Por meio de uma revisão bibliográfica são visitados alguns pensamentos sobre a formação dos estados nacionais e sobre as interações destes, produzindo conceitos relativos à ordem e ao equilíbrio em uma sociedade internacional, e aos fatores que afetam e são variáveis a existência dos estados. A designação teórica da realidade internacional desprovida de prescrições ou distorções ideológicas edifica neste ensaio valiosas linhas de pensamento, que podem contribuir significativamente para o desenvolvimento de proposições mais fidedignas a realidade do que a anseios específicos no campo das Ciências Políticas e das Relações Internacionais. ABSTRACT: The aim of this study is to construct of a way of thinking about the theories and the reality of International Relations based on the plurality of values and juxtaposition of ideas that mark and affect the relationships between international players. A further objective is understanding the influences of these factors in creating outcomes of cooperation or conflict within international interactions. Various thoughts and reflections on the formation of national states and their interactions have been examined by way of an intensive literature review, thus producing concepts concerning the order and equilibrium of an international society as well as the factors that affect and vary depending on the existence of states. Through the theoretical portrayal of the reality of international relations devoid of ideological prescriptions or distortions this study creates a number of lines of thinking, that could significantly contribute to the development of propositions more true to reality than specific aspirations within the field of Political Science and International Relations.

RED-Bridge: A Multiprotocol Tool Prototype for IoT Sensors

The IoT is growing more and more each year and is becoming so ubiquitous that it includes heterogeneous devices with different hardware and software constraints leading to an highly fragmented ecosystem. Devices are using different protocols with different paradigms and they are not compatible with each other; some devices use request-response protocols like HTTP or CoAP while others use publish-subscribe protocols like MQTT. Integration in IoT is still an open research topic. When handling and testing IoT sensors there are some common task that people may be interested in: reading and visualizing the current value of the sensor; doing some aggregations on a set of values in order to compute statistical features; saving the history of the data to a time-series database; forecasting the future values to react in advance to a future condition; bridging the protocol of the sensor in order to integrate the device with other tools. In this work we will show the working implementation of a low-code and flow-based tool prototype which supports the common operations mentioned above, based on Node-RED and Python. Since this system is just a prototype, it has some issues and limitations that will be discussed in this work.

Are torque values of preadjusted brackets precise?

OBJECTIVE: The aim of the present study was to verify the torque precision of metallic brackets with MBT prescription using the canine brackets as the representative sample of six commercial brands. MATERIAL AND METHODS: Twenty maxillary and 20 mandibular canine brackets of one of the following commercial brands were selected: 3M Unitek, Abzil, American Orthodontics, TP Orthodontics, Morelli and Ortho Organizers. The torque angle, established by reference points and lines, was measured by an operator using an optical microscope coupled to a computer. The values were compared to those established by the MBT prescription. RESULTS: The results showed that for the maxillary canine brackets, only the Morelli torque (-3.33º) presented statistically significant difference from the proposed values (-7º). For the mandibular canines, American Orthodontics (-6.34º) and Ortho Organizers (-6.25º) presented statistically significant differences from the standards (-6º). Comparing the brands, Morelli presented statistically significant differences in comparison with all the other brands for maxillary canine brackets. For the mandibular canine brackets, there was no statistically significant difference between the brands. CONCLUSIONS: There are significant variations in torque values of some of the brackets assessed, which would clinically compromise the buccolingual positioning of the tooth at the end of orthodontic treatment.

Estimation and prediction of parameters and breeding values in soybean using REML/BLUP and Least Squares

The aim of this study was to compare REML/BLUP and Least Square procedures in the prediction and estimation of genetic parameters and breeding values in soybean progenies. F(2:3) and F(4:5) progenies were evaluated in the 2005/06 growing season and the F(2:4) and F(4:6) generations derived thereof were evaluated in 2006/07. These progenies were originated from two semi-early, experimental lines that differ in grain yield. The experiments were conducted in a lattice design and plots consisted of a 2 m row, spaced 0.5 m apart. The trait grain yield per plot was evaluated. It was observed that early selection is more efficient for the discrimination of the best lines from the F(4) generation onwards. No practical differences were observed between the least square and REML/BLUP procedures in the case of the models and simplifications for REML/BLUP used here.

Predictive values of aspartate aminotransferase and gamma-glutamyl transferase for the hepatic accumulation of copper in cattle and buffalo

Ten cattle and 10 buffalo were divided into 2 groups (control [n = 8] and experimental [n = 12]) that received daily administration of copper. Three hepatic biopsies and blood samples were performed on days 0, 45, and 105. The concentration of hepatic copper was determined by spectrophotometric atomic absorption, and the activities of aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) were analyzed. Regression analyses were done to verify the possible existing relationship between enzymatic activity and concentration of hepatic copper. Sensitivity, specificity, accuracy, and positive and negative predictive values were determined. The serum activities of AST and GGT had coefficients of determination that were excellent predictive indicators of hepatic copper accumulation in cattle, while only GGT serum activity was predictive of hepatic copper accumulation in buffalo. Elevated serum GGT activity may be indicative of increased concentrations of hepatic copper even in cattle and buffalo that appear to be clinically healthy. Thus, prophylactic measures can be implemented to prevent the onset of a hemolytic crisis that is characteristic of copper intoxication.

Neutron Activation Analysis: A Primary (Ratio) Method to Determine SI-Traceable Values of Element Content in Complex Samples

The metrological principles of neutron activation analysis are discussed. It has been demonstrated that this method can provide elemental amount of substance with values fully traceable to the SI. The method has been used by several laboratories worldwide in a number of CCQM key comparisons - interlaboratory comparison tests at the highest metrological level - supplying results equivalent to values from other methods for elemental or isotopic analysis in complex samples without the need to perform chemical destruction and dissolution of these samples. The CCOM accepted therefore in April 2007 the claim that neutron activation analysis should have the similar status as the methods originally listed by the CCOM as `primary methods of measurement`. Analytical characteristics and scope of application are given.

Profiles of xylose reductase, xylitol dehydrogenase and xylitol production under different oxygen transfer volumetric coefficient values

BACKGROUND: Xylitol is a sugar alcohol (polyalcohol) with many interesting properties for pharmaceutical and food products. It is currently produced by a chemical process, which has some disadvantages such as high energy requirement. Therefore microbiological production of xylitol has been studied as an alternative, but its viability is dependent on optimisation of the fermentation variables. Among these, aeration is fundamental, because xylitol is produced only under adequate oxygen availability. In most experiments with xylitol-producing yeasts, low oxygen transfer volumetric coefficient (K(L)a) values are used to maintain microaerobic conditions. However, in the present study the use of relatively high K(L)a values resulted in high xylitol production. The effect of aeration was also evaluated via the profiles of xylose reductase (XR) and xylitol clehydrogenase (XD) activities during the experiments. RESULTS: The highest XR specific activity (1.45 +/- 0.21 U mg(protein)(-1)) was achieved during the experiment with the lowest K(L)a value (12 h(-1)), while the highest XD specific activity (0.19 +/- 0.03 U mg(protein)(-1)) was observed with a K(L)a value of 25 h(-1). Xylitol production was enhanced when K(L)a was increased from 12 to 50 h(-1), which resulted in the best condition observed, corresponding to a xylitol volumetric productivity of 1.50 +/- 0.08 g(xylitol) L(-1) h(-1) and an efficiency of 71 +/- 6.0%. CONCLUSION: The results showed that the enzyme activities during xylitol bioproduction depend greatly on the initial KLa value (oxygen availability). This finding supplies important information for further studies in molecular biology and genetic engineering aimed at improving xylitol bioproduction. (C) 2008 Society of Chemical Industry

Pupal Development of Ceratitis capitata (Diptera: Tephritidae) and Diachasmimorpha longicaudata (Hymenoptera: Braconidae) at Different Moisture Values in Four Soil Types

This study aimed to evaluate adult emergence and duration of the pupal stage of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), and emergence of the fruit fly parasitoid, Diachasmimorpha longicaudata (Ashmead), under different moisture conditions in four soil types, using soil water matric potential Pupal stage duration in C capitata was influenced differently for males and females In females, only soil type affected pupal stage duration, which was longer in a clay soil In males, pupal stage duration was individually influenced by moisture and soil type, with a reduction in pupal stage duration in a heavy clay soil and in a sandy clay, with longer duration in the clay soil As allude potential decreased, duration of the pupal stage of C capitata males increased, regardless of soil type C capitata emergence was affected by moisture, regardless of soil type, and was higher in drier soils The emergence of D longicaudata adults was individually influenced by soil type and moisture factors, and the number of emerged D longicaudata adults was three times higher in sandy loam and lower in a heavy clay soil Always, the number of emerged adults was higher at higher moisture conditions C capitata and D longicaudata pupal development was affected by moisture and soil type, which may facilitate pest sampling and allow release areas for the parasitoid to be defined under field conditions.

Evaluation of nutritional and genetic determinants of total homocysteine, methylmalonic acid and S-adenosylmethionine/S-adenosylhomocysteine values in Brazilian childbearing-age women

Background: Cobalamin (Cbl) and folate deficiencies and gene polymorphism of key enzymes or carriers can impair homocysteine metabolism and may change the serum values of S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH). We investigated the nutritional and genetic determinants for total homocysteine (tHcy), methylmalonic acid (MMA) and SAM/SAH in healthy Brazilian childbearing-age women. Methods: Serum concentrations of Cbl, folate, red blood cell folate, ferritin, tHcy, MMA, SAM, SAH and other metabolites were measured in 102 healthy unrelated women. The genotypes for MTHFR C677T, MTHFR A1298C, MTR A2756G, MTRR A66G, TC2 C776G, TC2 A67G and RFCI A80G gene polymorphisms were identified by PCR-RFLP. Results: Serum folate and Cbl were inversely correlated with tHcy and serum MMA, respectively. Cbl deficiency was associated with increased MMA and reduced alpha-aminobutyrate, serine and N-methylglycine concentrations. No variable was associated with SAM/SAH ratio. In addition, gene polymorphisms were not selected as determinants for tHcy, MMA and SAM/SAH ratio. Iron, Cbl and folate deficiencies were found respectively in 30.4%, 22.5% and 2.0% of individuals studied. Conclusions: There was a high frequency of Cbl and iron deficiency in this group of childbearing-age women. Serum folate and Cbl were the determinants of serum tHcy and MMA concentration, respectively. (c) 2007 Elsevier B.V. All rights reserved.
