    The main target of climate change policies in the majority of industrialized countries is to reduce energy consumption in their facilities, which would reduce the carbon emissions that are generated. Through this idea, energy management plans are developed, energy reduction targets are established, and energy-efficient technologies are applied to achieve high energy savings, which are environmentally compatible. In order to evaluate the impact of their operations and investments, companies promote measures of performance in their energy management plans. An integral part of measuring energy performance is the establishment of energy baselines applicable to the complete facility that provide a basis for evaluating energy efficiency improvements and incorporating energy performance indicators. The implementation of energy management systems in accordance with the requirements of ISO Standard 50001 is a contribution to the aim and strategies for improving cleaner production in industries. This involves an option for the industry to establish energy benchmarks to evaluate performance, predict energy consumption, and align production with the lowest possible consumption of primary and secondary forms of energy. Ultimately, this goal should lead to the manufacturing of cleaner products that are environmentally friendly, energy efficient, and are in accordance with the global environmental targets of cleaner manufacturing. This paper discusses an alternative for establishing energy baselines for the industrial sector in which several products are produced from a single raw material, and we determined the energy consumption of each product and its impact on the overall efficiency of the industry at the same time. The method is applied to the plastic injection process and the result is an energy baseline (EBL) in accordance with the requirements of ISO 50001, which serves as a reference for determining energy savings. The EBL facilitates a reduction in energy consumption and greenhouse gas emissions in sectors such as plastics, a sector which accounts for 15% of Colombia’s manufacturing GD

    The topic of online instructors’ roles has been of interest to the educational community since the late twentieth century. In previous studies, the identification of online instructors’ roles was done using a top-down (deductive) approach. This study applied a bottom-up (inductive) procedure to examine not only the roles of online instructors from a student perspective, but also how well these roles are implemented in practice. In the first stage, roles were defined using factor analysis on a sample of 925 students. A questionnaire was created after an extensive literature review and in-depth interviews with experts. The methodology detected six roles: pedagogical, course designer, social, life skills promoter, technical, and managerial. In the second stage, students’ scores were projected over those factors to obtain the instructors’ performance in each role (the significance of the results was assessed using non-parametric tests). Main findings included: (i) the emergence of a new role, the life skills promoter; (ii) online scenarios becoming more transparent and intuitive due to syllabus design; (iii) the consideration of more audio-visual resources by instructors in asynchronous learning environments; and (iv) the value of offering guidelines to students for collaborative activities to reduce the level of frustration with these activities

    Este trabajo pretende describir los problemas de conflictividad en centros de Educación Primaria a partir de la valoración del alumnado y analizar si existen diferencias entre niños y niñas. Han participado 1265 estudiantes (edad M= 11.11; DT= 0.75), muestra representativa de la población andaluza en España. La metodología utilizada ha sido analítica, a través de encuestas y un diseño transversal. Se han analizado cinco dimensiones negativas de la Escala de Convivencia Escolar (ECE): victimización, disruptividad, agresión, indisciplina y desidia docente. Los resultados señalan a la disruptividad como una de las principales fuentes de conflictividad y la existencia de diferencias en la Valoración de las dificultades analizadas entre chicos y chicas, siendo los chicos los que puntúan más alto en general, aunque no en todas las dimensiones. En la discusión y las conclusiones se aborda el impacto de las dificultades analizadas así como las diferencias entre ellos y ellas. Finaliza con una serie de Implicaciones educativas en torno a propuestas de actuación en función de las dificultades detectadas.This work pretends to describe the conflictive problems in the Primary Education Centers, starting with the valorization of the students and establishing whether there are differences between boys and girls. The participants are 1265 students (age M=11.11; DT=0.75), this sample is representative of the Andalusian population in Spain. The methodology employed has been analytical, by means of surveys and transversal design. Five negative dimensions of the Scale of School Behavior (SSB): victimization, disruption, aggression, indiscipline, teacher indolence were analyzed. The results show that disruption is one of the main sources of conflict and the existence of differences in the valorization of the difficulties between boys and girls analyzed, being the boys the ones that score higher in general although not in all the dimensions. In the discussion and conclusions the impact of the difficulties analyzed as well as the differences between boys and girls are dealt with. It ends up with a series of educational implications around the acting proposals in connections with the difficulties detected

    Regulation of Ace2-dependent genes requires components of the PBF complex in schizosaccharomyces pombe

    The division cycle of unicellular yeasts is completed with the activation of a cell separation program that results in the dissolution of the septum assembled during cytokinesis between the 2 daughter cells, allowing them to become independent entities. Expression of the eng1+ and agn1+ genes, encoding the hydrolytic enzymes responsible for septum degradation, is activated at the end of each cell cycle by the transcription factor Ace2. Periodic ace2+ expression is regulated by the transcriptional complex PBF (PCB Binding Factor), composed of the forkhead-like proteins Sep1 and Fkh2 and the MADS box-like protein Mbx1. In this report, we show that Ace2-dependent genes contain several combinations of motifs for Ace2 and PBF binding in their promoters. Thus, Ace2, Fkh2 and Sep1 were found to bind in vivo to the eng1+ promoter. Ace2 binding was coincident with maximum level of eng1+ expression, whereas Fkh2 binding was maximal when mRNA levels were low, supporting the notion that they play opposing roles. In addition, we found that the expression of eng1+ and agn1+ was differentially affected by mutations in PBF components. Interestingly, agn1+ was a major target of Mbx1, since its ectopic expression resulted in the suppression of Mbx1 deletion phenotypes. Our results reveal a complex regulation system through which the transcription factors Ace2, Fkh2, Sep1 and Mbx1 in combination control the expression of the genes involved in separation at the end of the cell division cycle

To access the final edited and published work see https://doi.org/10.7866/HPE-PE.17.1.3We study the program Préstamos Renta Universidad that provided loans to Master’s students in Spain between 2007 and 2010. We estimate predicted income functions and calculate individual repayment burdens and government cost using unconditional quantile regression analysis. We exploit the changing conditions of the successive calls to illustrate three important lessons for the design of student loan schemes: fixed monthly repayments exert an excessive burden to graduates at the lower end of the income distribution; general interest rate subsidies are costly to the taxpayer and unfairly distributed; while the deferment of payments due in case of hardship protects low earners, general grace periods are costly and inequitable

    In this paper, we have developed a classification model for online learning environments that relates the Instructors Overall Performance (IOP) rating (according to students’ perceptions) with the course characteristics, students’ demographics and the effectiveness of the instructor in his/her teaching roles. To that end, a comprehensive Student Evaluation of Teaching (SET) instrument is proposed, which includes not only conventional teaching elements, but also items that encourage twenty-first century skills. The goal of the study is twofold: (i) to quantify the extent to which the selected variables explain the IOP rating, and (ii) determine which teaching and non-teaching variables most affect the IOP rating. The best performing classifier achieved a competitive accuracy, highlighting that the selected variables mainly determine the IOP values. Other important findings include: (i) the IOP value is mainly influenced by the effectiveness of the instructor in his/her teaching roles; (ii) teaching strategies that involve the cooperation between the technical and pedagogical roles should be promoted; (iii) the pedagogical role has the highest impact on the final IOP value; and (iv) the most influential demographic variable is the student’s status (working commitments and family responsibilities)
