Beyond the mincer equation: the internal rate of return to higher education in Colombia
In order to present an estimation of the Internal Rate of Return (IRR) to higher education in Colombia we take advantage of the methodological approach provided by Heckman, Lochner and Todd (2005). Trying to overcome the criticism that surrounds interpretations of the education coefficient of Mincer equations as being the rate ofreturn to investments in education we develop a more structured approach of estimation, which controls for selection bias, includes more accurate measures of labor income and the role of education costs and income taxes. Our results implied a lower rate of return than the ones found in the Colombian literature and show that the Internal Rate ofReturn for higher education in Colombia lies somewhere between 0.074 and 0.128. The results vary according to the year analyzed and individual´s gender. This last result reinforces considerations regarding gender discrimination in the Colombian labor market.Education returns, Mincer Equation, Internal Rate of Return, Colombia

APORTACIONES DE A. AGUSTÍN Y G. FAERNO (MSS. 7901-2 BN) A LA ENMIENDA DE LOS FRAGMENTOS DE L. POMPINIO
The author of this article analyzes the metrical and critical emendations written by the humanists A. Agustín (1517-1586) and G. Faerno (1510-1561) to the text of L. Pomponius' 'Atellanae'. These unpublished notes, which may be found in the mss. 7901-2 from the BN of Madrid ('Fragmenta veterum latinorum scriptorum'), constitute the first attempt to put in order the extant fragments of the earlier latin poets. Unfortunately, this project remained unfinished, probably due to the publication of H. Estiènne's 'Fragmenta' (1564). In spite of the lack of a historical methodology, their research for the best and more appropriate 'lectiones', according to the general sense and the metrical structure of each fragment, leads our humanists to propose accurate conjectures still surviving in modern editions, though ascribed to later scholars. In other cases, their comments, which are no more than approximations and provisional answers, can help us to correct or, at least, to find out some errors in the textual tradition.The author of this article analyzes the metrical and critical emendations written by the humanists A.

La “desprotección” del suelo rústico frente a la ocupación ilegal. El caso del Cerro de San Miguel
En las últimas décadas se está produciendo un proceso de ocupación ilegal del suelo rústico, en concreto de los suelos limítrofes con el Albaicín y la Alhambra. La falta de reacción por parte de la Administración está provocando un efecto “llamada” que está teniendo como consecuencia que proliferen los asentamientos en zonas de gran valor histórico y ambiental. Así, han sido ocupados el Cerro de San Miguel, el Barranco de los Naranjos, el Barranco de los Negros, Valparaiso, laderas del Avellano, barrancos cercanos al Cementerio, ... Todos estos ámbitos cuentan con unas características comunes. Son zonas elevadas, de gran valor ambiental y paisajístico, aparentemente abandonadas, cercanas a la ciudad, pero separadas de la misma para no entrar en conflicto directo
El papel de las variables comunicativas en el desarrollo de sofisticación política entre los ciudadanos. Evidencias en la zona metropolitana de Monterrey
La exposición a los medios de comunicación y la atención a sus contenidos sobre política han sido contrastadas en numerosos estudios como factores explicativos del desarrollo de actitudes políticas entre los ciudadanos, que abarcan desde la generación de conocimiento político hasta su contribución al desarrollo de una mayor implicación y participación en el sistema de los ciudadanos. Un elemento central dentro de las actitudes políticas se encuentra en el nivel de sofisticación política, en tanto que muestra el conocimiento sobre el sistema político mantenido por la ciudadanía unido al nivel de interés con todo lo relacionado con la política de esas mismas personas. Para medir la relación
entre las variables comunicativas y el desarrollo de sofisticación política, se realizó una encuesta
representativa de la población de la Zona Metropolitana de Monterrey en el contexto postelectoral de 2012. Los resultados muestran cómo la atención a contenidos de política constituye la variable explicativa principal para el fortalecimiento de la sofisticación política ciudadana, aunque su impacto se produce gracias a la mediación realizada por la conversación interpersonal.
In several studies exposure to the media and attention to their political contents have been proven to be explanatory factors in the development of political attitudes among citizens, ranging from the generation of political knowledge to a contribution towards the development of greater citizen involvement and participation in the system. A central element of political attitudes is the level of political sophistication, given that it shows the public’s knowledge about the political system as well as their level of interest in matters relating to politics. To measure the relationship between communicative variables and the development of political sophistication, a representative survey of the population of the Metropolitan Area of Monterrey in the post-electoral context of 2012 was carried out. The results show how media attention is the main explanatory variable in the strengthening of political sophistication among citizens, although its impact is produced through mediation by
interpersonal conversation
Discovering Business Models for Software Process Management - An Approach for Integrating Time and Resource Perspectives from Legacy Information Systems
Business Process Management (BPM) is becoming the modern core to support business in all type of organizations and software business is not an exception. Software companies are often involved in important and complex collaborative projects carried out by many stakeholders. Each actor (customers, suppliers or government instances, among others) works with individual and shared processes. Everyone needs dynamic and evolving approaches for managing their software projects lifecycle. Nevertheless, many companies still use systems that are out of the scope of BPM for planning and control projects and managing enterprise content (Enterprise Content Management, ECM) as well as all kinds of resources (ERP). Somehow systems include scattered artifacts that are related to BPM perspectives: control and data flow, time, resource and case, for example. It is aimed to get interoperable BPM models from these classical Legacy Information Systems (LIS). Model-Driven Engineering (MDE) allows going from application code to higher-level of abstraction models. Particularly, there are standards and proposals for reverse engineering LIS. This paper illustrates LIS cases for software project planning and ECM, looking at time and resource perspectives. To conclude, we will propose a MDE-based approach for taking out business models in the context of software process management.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-

An integrated content modeling approach for educational modules
Educational modules – concise units of study capable of integrating theoretical/practical contents and supporting tools – can be seen as relevant mechanisms to facilitate the student’s apprenticeship. The establishment of processes and modeling approaches should ease the cooperative work to create, reuse and evolve educational modules, taking also into account the impact on the learning process. There are initiatives to address the problem of modeling educational contents, but none of them provides a complete set of features addressing the conceptual, instructional and didactic perspectives.
Moreover, these initiatives do not consider a systematic process for developing educational modules. In this work we summarize the main aspects of a standardized process for developing educational modules we have proposed, focusing on the modeling activity for structuring the learning contents. An integrated modeling approach is presented and its application is illustrated by the development of an educational module for the software testing domain.
The material produced has been applied and preliminarily evaluated in terms of the student's attitude toward content, usability and navigational aspects.Education for the 21 st century - impact of ICT and Digital Resources ConferenceRed de Universidades con Carreras en Informática (RedUNCI
