Relationship Amongst Technology Use, Work Overload, and Psychological Detachment from Work

Permanent connection to the work world as a result of new technologies raises the possibility of workday extensions and excessive workloads. The present study addresses the relationship between technology and psychological detachment from work resulting from work overload. Participants were 313 professionals from the health sector who responded to three instruments used in similar studies. Through PLS-SEM, regression and dependence analyses were developed, and through the bootstrapping method, significance of factor loadings, path coefficients and variances were examined. Results of the study corroborate a negative effect of technology use on psychological detachment from work and a positive correlation between technology and work overload. Additionally, there is a significant indirect effect of technology on psychological detachment from work as a result of work overload. Findings extend the literature related to the stressor-detachment model, and support the idea that workers who are often connected to their jobs by technological tools are less likely to reach adequate psychological detachment levels. Implications for the academic community and practitioners are discusse

Análisis de las medidas de asistencia a víctimas de trata de personas en Colombia en perspectiva de derechos humanos

La trata de personas se configura como una grave vulneración a los derechos humanos, lo cual obliga a los Estados a garantizar la asistencia y protección integral fundamentada en la reparación de quienes han sufrido dichas vulneraciones. A partir de la metodología de revisión documental, este artículo analiza la normativa aplicable a la asistencia y protección a víctimas de trata de personas en Colombia a la luz de los principios y directrices recomendados sobre derechos humanos y trata de personas. Los principios correspondena la no detención o enjuiciamiento por delitos relacionados con la condición de víctima de trata; protección y apoyo a víctimas; asistencia jurídica, protección y permisos de residencia temporales; derechos y necesidades de los niños; y regreso voluntario y en condiciones de seguridad. Los principales resultados evidencian que se han hecho importantes esfuerzos para incluir estas perspectivas de derechos humanos en la normativa colombiana. Sin embargo, solo se ha incluido como una directriz teórica en la mayoría de los documentos de trata de personas del país, sin traducirse en acciones concretas que favorezcan la recuperación de las víctimas

A graph editing framework for the StreamIt language

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2004.Includes bibliographical references (leaves 55-56).A programming language is more useful if it provides a level of abstraction that makes programming more intuitive and also allows the development of tools that take advantage of the language's internal representation. StreamIt, a language for the development of streaming applications, has a hierarchical and structural nature that lends itself to a graphical programming tool. I created a prototype StreamIt Graph Editor (SGE) to facilitate the development of streaming applications using StreamIt. The SGE provides intuitive visualization tools that allow developers to work more efficiently by automating certain processes. Thus, the programmer can focus more on design issues than on low level details that slow down the development process.by Juan C. Reyes.M.Eng

Evaluation of a customer loyalty strategy with system dymamics

The customer loyalty programs are a tool of differentiation and high impact to create long term relationships with customers of a company, so as to achieve an improvement in the portfolio and collections, redu­ced costs of customer service, increased revenue from higher sales to the most profitable customers, cross selling, among many other benefits. Ac­cordingly, we present a system dynamic model to analyze the economic benefits, in terms of profitability, which would be to implement a customer loyalty strategy. To adjust and validate the proposed model, its implemen­tation is done in a real case of a marketer of agricultural products in the department of Valle del Cauca - Colombia. The simulation results show that indeed the model fulfills its purpose, and that the loyalty program achieved significant results in the finances of the organization.Los programas de fidelización de clientes son una herramienta de diferen­ciación y alto impacto para crear relaciones de largo plazo con los clientes de una empresa, de tal forma que se logre una mejora en cartera y recaudo, reducción de costos de atención a clientes, incremento en ingresos por mayores ventas a los clientes más rentables, ventas cruzadas, entre muchos otros beneficios. De acuerdo con esto, se presenta un modelo de dinámica de sistemas que permita analizar los beneficios económicos, en términos de rentabilidad, que se tendrían al implementar una estrategia de fideliza­ción de clientes. Para ajustar y validar el modelo propuesto, se aplica en un caso real de una empresa comercializadora de productos agrícolas de la región. Los resultados de la simulación muestran que efectivamente el modelo cumple con su objetivo, y que el programa de fidelización logra importantes resultados en las finanzas de la organización

Additionally, Confirmatory Factor Analyses of the Life Satisfaction Scale and Coping Strategies Questionnaires are performed. Method. A cross-sectional study is conducted with 455 Colombian older adults, ranging from 65 to 92 years old. Results. The results show that problem-focused coping has a positive effect on SWB, whereas emotion-focused coping has a negative effect on SWB. Conclusions. This article highlights the relationship between effective coping and life satisfaction by showing that problem-focused coping strategies are adaptative and enhance well-being during agin

Numerical simulation and experiments of the multiphase flow in a liquid-liquid cylindrical cyclone separator

A Liquid-Liquid Cylindrical Cyclone separator (LLCC) is a device used in the petroleum industry to separate the oil-water mixture obtained from the well. The use of this device has not been widespread due to the lack of tools for predicting its separation capability. This paper presents a numerical and experimental study of the fluid dynamic performance of this type of cylindrical cyclone separators. The use of numerical simulations would reduce the time and cost necessary to obtain information for predicting the behavior of the equipment. The objective of this study is to determine if CFD (Computational Fluid Dynamics) techniques are able to reproduce the behavior of a LLCC separator. The CFD software examined was ANSYS-CFX 5.6TM and numerical simulations were carried out using the dispersed model with oil as the dispersed phase. The oil and water mixture entering the separator is divided due to centrifugal and buoyancy forces in an upper (oil rich) exit and a bottom (water rich) exit. The separation capability is determined as the maximum amount of water removed from the mixture with the minimum amount of oil content in the water rich exit. The experiments were conducted in a transparent LLCC separator that allows the visualization of the mixture and the measurement of the oil content. Experiments were conducted for three variables: mixture velocity and water content at the entrance, and the split ratio. The split ratio is defined as the bottom exit flow rate divided by the water flow rate at the entrance. The results showed that CFD tools are able to reproduce the oil content obtained from the experiments for all analyzed conditions. Additionally, the mixture distribution images from numerical and experimental data showed good agreement. This study confirms the capacity of CFD tools for the multiphase flow analysis of LLCC separators
