Purpose: Banks are institutions that inject money in the economy and help to boost it when there are problems in some markets, especially in productive sectors. In this way, analysing the competition in this sector is an important tool for policymakers as non-competitive behaviour could affect the financial system and economy. The purpose of this paper is to measure the degree of competition in the Ecuadorian private banking sector divided by size, from 2000 to 2015, using panel data collected by the official regulator institution. Design/methodology/approach: The authors applied the model proposed by Panzar and Rosse (1987) and its H-statistic using a reduced price and revenue equation estimated by pooled ordinary least squares, fixed effects, random effects, feasible generalised fixed effects and panel correction standard errors (PCSE). Findings: The authors show that given the presenc...

La empresa Servicios Agrícolas SAC presta servicios de volteo de tierras, actualmente cuenta con tres tractores agrícolas (massey ferguson, same y sonalika) con una programación de 12 horas diarias, durante la campaña 2018 el equipo con mayor índice de paradas imprevista es el tractor agrícola sonalika disminuyendo su disponibilidad mecánica hasta un 86% en promedio. Las paradas imprevistas por fisura de la estructura del cárter en el activo sonalika genera retraso en los trabajos programados, gastos adicionales de operación y mantenimiento para la empresa, debido a ello el objetivo de la presente investigación será analizar la estructura del cárter fisurado en el tractor agrícola sonalika en la empresa Servicios Agrícolas SAC, para cumplir con ello se recolecta información actualizada durante la campaña 2018, a través del reporte diario de cada activo de la empresa.

The study analyzes the environmental performance and the factors that can affect it in the case of construction sector companies. For this purpose, a sample of ISO 14001 certified construction companies in the Metropolitan area of Valle de Aburrá (Medellín, Colombia) was studied. The factors analyzed included training, management participation, community involvement, knowledge of environmental regulations, communication, and employee motivation. A case study methodology, descriptive observational, and exploratory in nature, was employed. The factors under review were analyzed based on the perception of coordinators and employees of the participating companies through the use of surveys. The results indicate that management and community involvement in environmental management are factors that influence environmental performance. On the other hand, factors such as training, the level of...

In radiosurgery treatments, there is always an absorbed dose (D) that is deposited outside the treatment field, this D is known as "Peripheral Dose" (PD). The objective of this work was to evaluate PD in 9 anatomical positions (eyes, thyroid, upper lungs, mediastinum, breasts and navel) of an anthropomorphic phantom. The development of the work contemplates the use of the EBT2 radiochromic films, and a photon beam of 6 MV generated in a linear accelerator Clinac 2100C / D. Analyzing the influence of collimator size, greater DP ((150.81 ± 0.97) cGy) was found in the right eye of the phantom for the collimator of 3 cm with a target fixed in the upper right plane of the head of the phantom and its influence with the distance of, a PD of (27.14 ± 1.04) cGy in the thyroid, for a target positioned in the lower left plane of the phantom head for a prescribed dose of 18 Gy. It is concluded tha...
