Los padres ocupan un lugar muy importante en el crecimiento de los hijos, siendo uno de los principales garantes de un adecuado logro de las diferentes tareas que los hijos enfrentan en cada etapa. Así pues, por un lado, favorecen el desarrollo saludable proveyéndoles del sostén y acompañamiento que ellos necesitan (Carver y Scheier, 1997; Kantrowitz y Springen, 2005). Por otro, actúan como factor protector ante problemas de conducta, dificultades académicas, depresión, etc. (O’Connor, 1995; McCurdy y Scherman, 1996; Klein, Forehand, Armistead, Long, 1997; Ausloos, 1998; Wittekind y Vazsonyi, 2003).

El desarrollo de software es una actividad demandada por el mundo entero, en el que se requiere de habilidades técnicas y blandas para desempeñarse con destreza en una carrera tan globalizada y competitiva. Las investigaciones revisadas muestran la existencia de una brecha entre la industria y la academia. Los centros de formación proveen a los profesionales de habilidades técnicas, sin embargo en estos ultimos tiempos manifiesta la necesidad de contar con habilidades blandas, por lo que es clave estudiarlas y encontrar maneras de poder insertarlas en los profesionales que se integran a la industria. Existe una metodología llamada PSP creada por Watts Humphrey, que ayuda a cada individuo a fortalecer sus destrezas en el proceso de desarrollo de software, a pesar de eso, el método no es muy difundido en la académia y la industria. Esta investigación muestra la importancia de las h...

En los orígenes de la ciencia de la computación todo el énfasis estuvo puesto en desarrollar sistemas que automatizaran tareas que se hacían manualmente. Este era suficiente desafío. En la actualidad, se han automatizado muchas tareas y el gran desafío es cómo mejorar la capacidad de los sistemas para alcanzar nuevos requerimientos: agregar nuevas interfaces, combinar múltiples fuentes de datos en una sola, interactuar con dispositivos móviles y reemplazar viejas aplicaciones con nuevas. La tendencia de hoy es hacia un paradigma orientado a los procesos, donde las aplicaciones cubren la actividad global de la empresa y las herramientas son los BPMS (Business Process Management Systems o Sistemas de Gestión de Procesos de Negocio). Los modelos actuales resultan insuficientes porque son pobres en su integración y se orientan a describir datos y transacciones. El cambio de enfoqu...

Mathematical modelling applied to batch milling (at experimental level), is a very important tool to simulate and predict the granulometric yield of a given treated ore; this means, for a given duration of milling operation, to obtain an estimate of the corresponding granulometric analysis, which can then be tested with real data later on, to verify the estimates. The model involves the selection and fracture functions depending on each mesh size in the ore distribution. This will allow the prediction of effective and reliable results, saving costs and more importantly, time, without the need to perform the milling process for each prediction of batch milling.

One characteristic that best defines today's society is the production of waste, this being higher in so-called "developed" countries. Virtually no human activity that does not generate any waste also exist a direct relationship between the standard of living of a society or country and the amount of waste generated. Approximately 23% of the world population lives in developed countries consume 78% of resources and produces 82% of the waste [Black and Malate, 1996]. Furthermore, the volume of waste grows exponentially with the level of industrialization of a country. There are currently about five million registered substances known of which approximately 70,000 are widely used throughout the world, estimated at about 1,000 new chemicals each year are added to the list.

The Soxhlet method in extracting plasticizers from PVC compounds presents various areas for improvement, such as the amount of solvent used, the time required in the process, and its costs. This study proposes replacing the Soxhlet method with the ultrasound-assisted method to reduce the time, costs, and amount of solvent used in plasticizer extraction. It also proposes using solvent recovered from previous extractions to reduce costs further. The study involved experimentation with three different grades of PVC compounds (medical, cable, and profile) to compare the recovery of plasticizers by the Soxhlet and the ultrasound-assisted methods. The plasticizers obtained were analyzed using gas chromatography, gas chromatography coupled with mass spectroscopy, and Fourier-transform infrared spectroscopy to evaluate the results of each extraction method as compared to reference co...

This study focuses on enhancing the competitiveness of small and medium-sized companies (SMEs) specializing in heavy equipment maintenance. It introduces an innovative model that links the operational efficacy of technical processes to the overall effectiveness of maintenance services. This approach considers all elements of the value chain, including the processes and resources involved at each stage. The research highlights that a gap in the technical development of these processes hinders companies from achieving optimal outcomes due to inconsistency in maintenance methods. To address this challenge, a quantitative study has been conducted to explore the causal relationship between the efficacy of technical processes and the effectiveness of maintenance services. This research study aims to identify strategies that enable companies to improve their performance in this area.

This article presents the problem of defining the concept of “competence”, due to it being an integral and complex term that has been applied in many domains as well as in a more general sense for everyday life. However, no doubt, a competence can only be tested and valuated in the practice, and it is a person who becomes competent in a context for a certain function. This is why there are many different conceptions in the literature regarding this issue; it’s a consequence of its imprecise, variable character. However, the position profiles (mainly in educational entities) and the acceptation/ graduation profiles are being more and more frequently established in terms of competences. This paper intends to check what has been valuated and written about the managerial competences training and development regarding the educational field, in order to obtain conclusions regarding its d...
