A mixed-integer linear programming model for harvesting, loading and transporting sugarcane. A case study in Peru

Abstract: Due to opportunities for economic and social development in the biofuels market, improvement to the supply chain has become a relevant matter. In agro-industrial supply chains, procurement costs are highly relevant. Since sugarcane is a high performance raw material for ethanol production, this paper proposes a Mixed-Integer Linear Programming Model for cost optimization for harvesting, loading and transportation operations. The model determines the quantity of machines and workers to meet the biofuel plant requirements. Costs of resources for harvesting and loading as well as transportation costs from the land parcel to the production plant are minimized. Also, the model calculates the cost of penalties for shortages (unmet demand) and the cost of equipment idle time. The implementation of the model in a Peruvian biofuels company, showed a cost reduction of around 11 % when compared to the current costs.

La evaluación del desempeño docente

Abstract: This paper accounts for the process that led to the construction of a public policy about teaching assesment in Colombia. Teaching performance assessment in this country has been a controversial issue during the last decades, as it is one of the tools favored by the government to impact the quality of education. The discussion about its pertinence, its conception and its characteristics becomes the meeting point of different actors that, while looking for the best option to characterize teachers’ performance and assessment, have allowed for the statement of some public policy trends on the issue. The paper accounts for this process.

El Compromiso Ambiental de Instituciones de Educación Superior en Colombia

Abstract: espanolEl proposito de este articulo es presentar una vision actualizada de los avances logrados por instituciones de educacion superior [IES] del pais en el proceso de institucionalizacion del compromiso ambiental. Se indaga por la inclusion de los temas ambientales en ambitos que incluyen, ademas de las funciones sustantivas de docencia, investigacion y extension, las politicas institucionales y la participacion, gestion y ordenamiento ambiental. La encuesta fue diligenciada por 60 IES publicas y privadas, ubicadas en diferentes regiones del pais. El caracter de la investigacion es cualitativo, de tipo exploratorio, apoyado en analisis de estadistica descriptiva y elaborada con base en una escala establecida para cada ambito a partir de porcentajes que definen los niveles de compromiso ambiental de cada una de las IES. El ambito de desempeno mas alto fue el de gobierno y participacion, lo cual muestra el interes de las IES por fortalecer las politicas ambientales. El mas bajo fue el de gestion y ordenamiento del campus. Estos resultados establecen la necesidad, de generar estrategias de autorregulacion y mejoramiento institucional, y promover procesos de continuidad de esta investigacion. EnglishThe aim of this article is to present an updated overview of the progress achieved by Higher Education Institutions (HEIs) in Colombia in the institutionalization of the environmental engagement. The document explores the incorporation of environmental issues into domains including, in addition to the fundamental activities—teaching, research, and extension—institutional policies and participation, and environmental planning and management. A survey was conducted with 60 private and public HEIs located in different regions of the country. This is a qualitative exploratory research supported by analysis of descriptive statistics. It was carried out based on a scale fixed for each domain, which uses percentages as a basis for indicating the levels of environmental engagement of each of the HEIs. Governance and participation constituted the highest-performing domain, showing the interest of the HEIs in strengthening environmental policies. Campus management and planning was the less-performing domain. These results establish the need to generate self-regulation and institutional improvement strategies, and to promote processes for further research. francaisL’objectif de cet article est de presenter un apercu actualise des progres accomplis par les Institutions d’Enseignement Superieur (IES) en Colombie dans le processus d’institutionnalisation de l’engagement envers l’environnement. Le document examine l’incorporation de questions environnementales dans des domaines tels que les politiques institutionnelles et la participation, la gestion et l’amenagement du territoire, outre les activites fondamentales d’enseignement, de recherche, et de vulgarisation. Une enquete a ete menee aupres de 60 IES publiques et privees situees dans diverses regions du pays. La presente etude est de caractere exploratoire et qualitatif, etayee par une analyse de statistique descriptive, et elaboree sur la base d’une echelle etablie pour chaque domaine, dont l’usage de pourcentages determine le niveau d’engagement vers l’environnement de chacune de ces IES. Le domaine le plus performant a ete celui de la gouvernance et la participation, ce qui indique l’interet des IES de renfoncer les politiques environnementales. Le moins performant correspond a la gestion et l’amenagement du campus. Ces resultats soulignent la necessite d’elaborer des strategies d’auto-regulation et d’amelioration des institutions, et la necessite de promouvoir des processus de poursuite de cette recherche. portuguesO proposito deste artigo e apresentar uma visao atualizada dos avancos logrados pelas instituicoes de educacao superior [IES] do pais no processo de institucionalizacao do compromisso ambiental.

This text take a reference the legal systems of countries such as Chile, Argentina, Peru and Mexico in the decades of 1990-2010, to review and to characterize the introduction of the neoliberal discourse as a key piece of the field training latinamerican legal.

Metodología para la Predicción del Grado de Riesgo Psicosocial en Docentes de Colegios Colombianos utilizando Técnicas de Minería de Datos

Abstract: espanolEn este articulo se presenta la aplicacion de la mineria de datos en diagnosticos de evaluaciones psicosociales para la identificacion del grado de riesgo psicosocial en docentes de educacion basica primaria y media secundaria en Colombia. Se tomo una muestra de datos de 1100 registros, correspondientes a evaluaciones personales. Se realizo la revision y limpieza de los datos para poder utilizarlos como entradas en la herramienta de mineria de datos WEKA. Se comparan los resultados obtenidos al aplicar las tecnicas de mineria de datos, arboles de clasificacion J48 y Naive Bayes. Finalmente se obtiene como resultado las caracteristicas psicosociales predictivas con una efectividad del 91% comparado con el diagnostico clinico. Se concluye que la herramienta puede ser usada como un instrumento para la prevencion de la aparicion de factores de riesgo psicosocial en docentes de colegios publicos colombianos. EnglishThis paper proposed the application of data mining to identify the psychosocial risk level in teaching elementary, middle y high school education in Colombia. A sample of 1100 data records corresponding to individual assessments were analyzed and processed. The samples were used as input data to the data mining tool called WEKA. Results were compared to assess the performance when applying data mining techniques and classification trees J48 and Naive Bayes. Finally, the application of this predictive tool allows the accuracy 91% compared to the clinic diagnostic. It is concluded that the method can be used tool for preventing the occurrence of psychosocial risk factors in Colombian public school teachers.
