Shakespeare hizo famosa la frase: ¡Cuídate de los idus de Marzo! con la que se advertía a Julio César sobre el peligro que representaba salir de casa en estas fechas. Esta frase recogía la leyenda de Plutarco que comentaba que el emperador romano Julio César había sido advertido de los problemas potenciales en una profecía y precisamente fue asesinado en esos días (1). Desde entonces, el mes de marzo es considerado un mes de cambios y potenciales problemas como los que atraviesa en estos momentos nuestro país.

A problem in many schools is the difficulty of students to understand texts, which is due to multiple factors, including habits and motivation to read. On the other hand, augmented reality is a didactic technology which, when applied to the educational area, becomes a dynamic, interactive activity and arouses interest in the student. This study shows the results obtained after the application of augmented reality for reading comprehension through stories in fourth grade primary students. A mobile application based on augmented reality named “IdeAR” was implemented using Mobile-D methodology. For empirical demonstration the statistical sample included two sections of students from a public school in Lima city, where the experimental group showed improvements in memory level and content understanding. Finally, this work is important for the educational sector because it provides a tool...

This short communication complements the DEA model proposed by Lovell and Pastor (Eur. J. Oper. Res. 118 (1999), 46-51), by incorporating both positive and negative criteria in the model. As such, we propose a DEA model, known as pure DEA, using a directional distance function approach.

In this paper, we propose a method to measure competitiveness performance at the subnational level, with an application to Peruvian regions. For this, we propose a benefit-of-the-doubt composite index that summarizes the information of several indicators that characterize competitiveness. It is based on an optimization approach, using Data Enveloping Analysis (DEA) techniques, so that each indicator is weighted in an endogenous way, and each unit is evaluated in the most favourable light. Our proposed index is a non-radial variant of the typical DEA scores, which avoids the traditional pitfalls of DEA-based composite indexes, such as unreasonable weights. Additionally, we propose a meta-frontier approach in order to compare the competitiveness performances across different periods of evaluation. Our assessments of the Peruvian regions' competitiveness performance improve on the results o...

The performance of the airline industry has been widely studied using data envelopment analysis (DEA). Many existing DEA-based airline performance studies have used the standard DEA model, with some minor modifications. These studies have ignored the internal structure relative to the measures characterizing airline operations performance. In the current paper, airline performance is measured using a two-stage process. In the first stage, resources (fuel, salaries, and other factors) are used to maintain the fleet size and load factor. In the second stage, the fleet size and load factors generate revenue. The model used is called the centralized efficiency model where two stages are used to optimize performance simultaneously. The approach generates efficiency decomposition for the two individual stages. The use of this centralized DEA model enables obtaining insights not available from ...

Ever since the inception of brand values, these have become a benchmark for many data-driven strategies, eventually providing a basis for vertical/horizontal integrations, as well. In recent decades, brands have become comparable across the industries, based on their value derived either from the customer perception or in terms of the firm financials. Numerous models have been developed in time to measure the customer-based brand equity; nevertheless, they all evaluate brand equity in an absolute sense. The present research paper provides an avenue to measure the customer-based brand equity in a relative sense using a satisficing DEA model. The information for this model has been collected through a customer-based survey questionnaire in line with predefined brand equity dimensions, which have been verified through a confirmatory factor analysis. We demonstrate the approach by means of a...

The purpose of this paper is to evaluate the performance of a sample of natural resources exchange traded funds (ETFs) by applying a two-stage procedure. In the first stage, the generalized proportional distance function (GPDF) in the data envelopment analysis (DEA) context is used for the first time to measure the relative efficiency of sectoral ETFs. In the second stage, a Tobit model is employed to identify the drivers of performance. The results indicate there is scope for efficiency improvement for about half or more of the sample funds depending on the variables used in the assessments, and fund performance can be explained by fund persistence and the beta coefficient.

Benchmarking has been suggested as a useful regulatory tool for water companies in both developed and developing countries, specially due to the predominance of public firms in these sectors. However, in order to be effective, the comparison should be about credibly reflecting differences in the firms' performances, rather than capturing differences in their operating contexts. In this paper I apply a conditional data envelopment analysis (DEA) benchmarking technique that specifically controls for these different operating environments. As a result, I find that conditioning on the population density in each firm's area of operation affect the estimated efficiencies in a significant way. The results are consistent with previous findings in other countries (which use different methodologies), and are new in the case of Peru.

The measure proposed in this paper is a new nonparametric data envelopment analysis (DEA) scheme, the hybrid measure, for determining efficiency in the presence of radial and nonradial inputs or outputs. Further extension of the scheme occurred to address nonseparable desirable and undesirable outputs. Applying the model to measure the overall efficiency of U.S. electric utilities in the presence of both desirable and undesirable outputs indicated that the utilities had improved their overall management and environmental efficiency between 1996 and 2000.

Competitiveness provides higher levels of productivity, efficiency and quality, hence its importance to measure it. This paper presents a DEA model to measure the competitiveness of Peruvian textile sector manufacturers. The proposed model consists of two phases: the first phase, measures the levels of development of quality, innovation and efficiency of the companies; the second phase the competitiveness of companies considering their quality innovation and efficiency. To illustrate the proposed model, the SIAD software applied to 16 companies in the textile manufacturing sector was used, and the ranking of companies by each factor and competitiveness is shown.

Las instituciones de microfinanzas (IMF) en el Perú se pueden agrupar en Cajas Municipales de Ahorro y Crédito (CMAC), Cajas Rurales de Ahorro y Crédito (CRAC) y Empresas de Desarrollo de la Pequeña y Micro Empresa (EDPYME). Los tres tipos de IMF se diferencian desde su origen por el objetivo, la coyuntura económica y política, y el marco legal bajo el cual fueron creados. De acuerdo con el marco normativo, cada uno de los sistemas microfinancieros se encuentra autorizado a realizar diferentes tipos de operaciones, y el universo de dichas operaciones no es el mismo que el permitido a las empresas bancarias. Este trabajo intenta responder a dichos planteamientos y analiza la eficiencia relativa de las IMF aplicando una herramienta no tradicional: el análisis envolvente de datos (DEA, por sus siglas en inglés). El trabajo se divide en cuatro secciones. En la primera sección se des...

The performance of discrete element method (DEM) simulations is highly dependent on the requirements of the associated algorithms in terms of computer memory usage and CPU time. In particular, computer CPU time heavily depends on the identification of neighbor particles and the computation of particle-particle interactions. Over the years several neighbor particles searching methods have been developed. Accordingly, in this work the performance of two of well-known searching methods, linked cell and Verlet tables algorithms, are assessed in the context of the development of a new DEM-based tool. More specifically, the neighbor searching methods performance and related computational costs are parametrically analyzed and an assessment of their suitability for carrying the intended numerical simulations is provided. The referred numerical simulations are performed accounting for a canonical...

The aim of this paper is to analyze the technical efficiency of the companies that operated on the electric power distribution sector in Peru from 1995 to 1998. For this purpose we will employ Data Envelopment Analysis (DEA), and we will point out the main advantages and limitations of this technique. This well-known non-parametric and deterministic tool is used to empirically build the production frontier in this sector. Finally, we will discuss about the topic of efficiency in the public sector comparing the average performance according with the ownership of the capital for public, privatized and private companies. From this empirical analysis we conclude that the privatization process, per se, does not suppose improvements of efficiency respect to public companies if we do not capture others characteristics of the market.
