Contribución del comercio electrónico al desempeño de las PyMEs industriales: un modelo estructural

El rol que juegan las Tecnologías de la Información y comunicación (TIC) para lograr un mejor desempeño organizacional aún requiere de un análisis más profundo entre las pequeñas y medianas empresas (PyMEs) de los países en desarrollo. Este estudio pretende ampliar la literatura empírica sobre la relación entre TIC, comercio electrónico y desempeño de las PyMEs en países en desarrollo. Para alcanzar este objetivo, utilizamos una muestra de 87 empresas manufactureras de la ciudad de Bahia Blanca, Argentina correspondiente al año 2015. Mediante la estimación de un Modelo de ecuación estructura, se obtiene que la adopción del comercio electrónico posee una influencia positiva y significativa en las ventas de las PyMEs la cual es potenciada por el nivel de uso de las TIC. Otros factores organizacionales tales como el tamaño de la empresa y los programas públicos explican el desempeño, pero no son predictores significativos de la adopción del comercio electrónico.The role Information and Communication Technologies (ICT) play in achieving a better organizational performance still needs further analysis among small and medium sized enterprises (SME) from developing countries. This study aims to extend the empirical literature on the relationship between ICT, electronic commerce and SME performance in developing countries. To achieve this goal, we employ a sample of 87 manufacturing firms from the city of Bahía Blanca, Argentina in the year 2015. By estimating a structural equation model, we obtain that electronic commerce adoption has a positive and significant influence on SME sales which is reinforced by the level of ICT use. Other organizational factors such as firm size and public programs explain performance, but are not significant predictors of the electronic commerce adoption.Fil: Alderete, Maria Veronica.

The Common Core: An Enhancement or Hindrance for the Youth of America?

Education in America differs from other nations and may benefit from modeling some of these foreign practices. Although there are many improvements that the country could make, curriculum could be one of the sources of inadequacy in the education system and is often what receives the most attention. Therefore, the subsequent sections will explore the United States’ major attempt in improving education through creating consistency through the Common Core curriculum. In all, if the United States seeks to maintain its power in various sectors, it must strengthen its education system to ensure success

A real-time, dual processor simulation of the rotor system research aircraft

A real-time, man-in-the loop, simulation of the rotor system research aircraft (RSRA) was conducted. The unique feature of this simulation was that two digital computers were used in parallel to solve the equations of the RSRA mathematical model. The design, development, and implementation of the simulation are documented. Program validation was discussed, and examples of data recordings are given. This simulation provided an important research tool for the RSRA project in terms of safe and cost-effective design analysis. In addition, valuable knowledge concerning parallel processing and a powerful simulation hardware and software system was gained

Effect of supplementary cementitious materials on capillary sorption : relation with drying rate and testing time

The water sorption phenomenon in a cementitious matrix is responsible for the ingress of several deleterious agents, and it is directly related to pore connectivity and pore volume. One of the most common tests used to describe this mechanism is the capillary sorption test. Furthermore, the drying rate (DR) is a process that strongly depends on the transport properties and also provides valuable information related to porosity and durability. Supplementary cementitious materials (SCMs) are known to enhance durability-related properties, especially pore refinement with time due to the pozzolanic action. Therefore, changes in the pore structure could be assessed by means of the capillary sorption and drying rate. For this study, mortars with ground granulated blast-furnace slag, natural pozzolan and limestone powder at three different levels of replacement were made and the capillary sorption test was performed at 28 and 90 days. Weight loss was also assessed at 28 days and the DR was calculated. Calculation of the weight gain, weight loss, DR and capillary sorption rate (CSR) is made considering the stoppage of the test at different stages. A comparison between different approaches in the calculations is made. Also, the relation of DR and CSR is assessed. Results show the effect of SCMs with time, and also the influence of the calculations on the CSR and DR values

Los movimientos campesinos frente a la dominación y concentración del poder en Paraguay

Anais das IV Jornadas Internacionais de Problemas Latino-Americanos: Lutas, Experiências e Debates na América Latina - ISBN 978-950-793-223-6 - Orgs. Paulo Renato da Silva ; Mario Ayala ; Fabricio Pereira da Silva ; Fernando José MartinsEl interés de este trabajo gira en torno al papel que juegan las organizaciones campesinas en la histórica lucha contra la desigualdad e injusticia que caracterizan al país, y sobre posibles escena- rios futuros partiendo del actual contexto que se presenta al menos conflictivo. Los movimientos campesinos son quienes ejercen la mayor presión contra este modelo excluyente, donde la pose- sión o no de la tierra es la que estructura el poder. En el 2008 con Fernando Lugo en la presidencia, se presentó la posibilidad de un nuevo juego político donde los movimientos campesinos tuvieron mayor capacidad de acción y una presencia diferente en el escenario público. Este gobierno fue interrumpido por medio de un juicio político al presidente, luego de la masacre ocurrida en Curuguaty que dejó doce muertos, la mayoría de ellos campesinos. Con el actual gobierno de Cartes las políticas neoliberales están a la orden del día, el avance de los agronegocios es más intenso y la conflictividad social adquiere mayor presencia.PPG – IELA – UNIL
