Authors: Navarro Roldan Claudia Patricia , Corredor Aristizabal Javier 
Published: June 2018

EspañolEn este artículo se analiza cómo los estudiantes de primaria y secundaria, en colegios rurales y urbanos, reconstruyeron la historia sobre la Independencia Colombiana. Se realiza una investigación observacional descriptiva con una medida transversal, la cual involucró una pregunta generativa de narración aplicada a 43 estudiantes, seleccionados intencionalmente, de quinto de primaria con edad promedio de 10.39 y octavo grado de secundaria con edad promedio de 13.12. El análisis de independencia o relación de las categorías de análisis incluyó el conocimiento historiográfico (e.g., el uso de fuentes históricas, factores explicativos, temporalidad histórica), y la estructura de la narrativa como un tipo de discurso (e.g., uso de secciones narrativas del modelo Labov y Waletzky, 1967/1997). Se encontró que las producciones orales de los estudiantes, a nivel de su macroestructura narrativa e historiográfica, fueron poco sofisticadas y lejanas al discurso disciplinar histórico. Además, las narra tivas históricas en contextos rurales y urbanos fueron similares. Para concluir, se sugiere la necesidad de revaluar el tipo de narraciones históricas, que circulan en las aulas escolares, como una forma de incrementar el nivel de complejidad histórica en los relatos disponibles sobre la independencia.EnglishWe analyze how the students of primary and secondary schools, from rural and urban areas, reconstructed the history of Colombian Independence. We developed a descriptive observational study with a cross-sectional measure involving a narration generating question applied to an intentionally selected sample of 43 students. We analyzed the independence or relation of the categories: historiographic knowledge (e.g., the use of historical sources, explanatory factors, historical temporality), and narrative macrostructure (e.g., use of the Labov and Waletzky model, 1967/1997). Results indicated oral productions by the students, from narrative and historiographic macrostructures, were unsophisticated and far from the historical disciplinary discourse. In addition, historical narratives in rural and urban contexts were similar. We suggest the need to re-evaluate the kind of historical narratives circulating in the school classrooms, as a way to increase the level of historical complexity in the available stories about independence.

SUMMARY

Objectives:
This study compared light transmission through different thicknesses of bulk-fill resin-based composites (RBCs) using a polywave and a single-peak light-emitting diode light-curing unit (LCU). The effect on the surface hardness was also evaluated.

Methods:
Five bulk-fill RBCs were tested. Specimens (n=5) of 1-, 2-, 4-, or 6-mm thickness were photopolymerized for 10 seconds from the top using a polywave (Bluephase Style) or single–peak (Elipar S10) LCU, while a spectrophotometer monitored in real time the transmitted irradiance and radiant exposure reaching the bottom of the specimen. After 24 hours of storage in distilled water at 37°C, the Vickers microhardness (VH) was measured at top and bottom. Results were analyzed using multiple-way analysis of variance, Tukey post hoc tests, and multivariate analysis (α=0.05).

Results:
The choice of LCU had no significant effect on the total amount of light transmitted through the five bulk-fill RBCs at each thickness. There was a significant decrease in the amount of light transmitted as the thickness increased for all RBCs tested with both LCUs (p&lt;0.001). Effect of LCU on VH was minimal (ηp2=0.010). The 1-, 2-, and 4-mm-thick specimens of SDR, X-tra Fill, and Filtek Bulk Restorative achieved a VHbottom/top ratio of approximately 80% when either LCU was used.

Conclusions:
The total amount of light transmitted through the five bulk-fill RBCs was similar at the different thicknesses using either LCU. The polywave LCU used in this study did not enhance the polymerization of the tested bulk-fill RBCs when compared with the single-peak LCU.

Published: June 2018

SUMMARY

Objective:
To evaluate, in vitro, the effect of mouth rinse exposure on bleached enamel.

Methods:
Enamel/dentin bovine blocks (4×4×2 mm) were bleached with 35% hydrogen peroxide (HP) and were submitted to immersion twice daily for 14 days with different rinses (n=10), including those involving: distilled water (C [control]), 225-ppm NaF (FM, Colgate Plax Classic), essential oil (EM, Listerine Tartar Control), 1.5% hydrogen peroxide (HPM, Colgate Plax Whitening), and 2% hydrogen peroxide, pyrophosphates, and 225-ppm NaF (HPM+P, Colgate® Luminous White). The specimens were stored in a remineralizing solution during all experiments. Analyses of color (ΔE, L*, a*, b*) and roughness (Ra) were performed at the baseline, after HP, and after exposure to the rinse. The cross-sectional microhardness (CSMH) and images by scanning electron microscopy (SEM) were assessed at the end. The data were subjected to analysis of variance (ANOVA) (ΔE), repeated measures ANOVA (Ra), and split-plot ANOVA (CSMH), followed by the Tukey test. The L*, a*, and b* values were analyzed by generalized linear models (α=0.05).

Results:
Color changes were not statistically different in the groups. Ra increased in all groups after bleaching; however, it was reestablished in C, FM, and HPM+F and increased in EM after 14 days of the rinse. EM and HPM reduced the CSMH values differing from C and promoted alterations on the enamel surface visualized by SEM.

Conclusion:
The mouth rinses did not affect the whitening efficacy or promote benefits on bleached enamel properties. Moreover, the 1.5% hydrogen peroxide– or essential oil–based mouth rinses affected the bleached enamel properties, promoting an alteration in morphologic surface and mineral loss in depth.

Published: June 2018

Be it industry or academia, Internet of the Things (IoT) has become buzzword today. Everyone is expecting a system of gadgets controlled by web without human intervention. The concept has opened many possibilities and a fear of failure too. All over the world the research is going on and few organizations have already started implementing the concept at a small level. But the available research is still immature and undirectional. The area is very young, the research too. Hence there is a need to develop an IoT architecture which is universally acceptable by various IoT objects as well as server. To facilitate with the need, the paper presents a novel IOT architecture. In addition, the interaction of IoTobjects with each other has been discussed alongwith connection of a server’s infrastructure with another server’s infrastructure through API gateway.

Published: June 2018

In recent times many studies have revealed that emotional intelligence influence the job performance of employees in a big way. “Emotional intelligence is the ability of an individual to appropriately and successfully respond to a vast variety of emotional stimuli being elicited from the inner self and immediate environment. Emotional intelligence constitutes three psychological dimensions; emotional sensitivity, emotional maturity and emotional competency, which motivate an individual to recognise truthfully, interpret honestly and handle tactfully the dynamics of human behaviour.” (Singh, 2001) Using this definition of emotional intelligence by Dr.Dalip Singh as the operational definition and the EQ test developed by Dr.Dalip Singh & N.K.Chadha, this study attempts to measure the emotional intelligence of Indian corporate employees and explore the dynamics between their emotional intelligence and job performance. This study was conducted by collecting primary data from corporate employees through questionnaires for measurement of EQ. To ascertain Job performance of employees, secondary data was collected by obtaining performance ratings from the HR departments. The study covered 216 samples from five organisations from the manufacturing sector located in Mysore and Mandya district in the State of Karnataka.

The position of Ecuador, according to indicators of innovation and competitiveness on a global scale, expose problems that in general affects the Ecuadorian industry, specifically the metal-mechanical one, that is considered an important source of employment and revitalization of the country's economy since 2010. The government has prioritized the metal-mechanical industrial sector as one of the strategic sectors for the transformation of the productive matrix of the country. The small and medium enterprises (SMEs), included in this sector, have problems associated with their technological resources, that have been turned into challenges to be faced in order to reverse the situation. This paper shows the results of a situational diagnosis aimed at identifying the problems related to the management of the processes of technology transfer in the sector that includes the analysis of the administrative, technical, technological, and economic factors involved in these processes in a selected group of SMEs, as well as their social, economic and environmental impact. The main results achieved in the design of an alternative and complementary methodological procedure are presented. The procedure is supported by a set of engineering and management tools to execute an important process of technology management, the technology transfer with strategic scope, aimed at increasing competitiveness with social responsibility.

Beyond the City of Modernism: a counter-narrative of industrial culture
Authors: Glorius Birgit , Manz Katja 
Published: June 2018

Abstract
This paper unfolds around an empirical experiment, which aimed to reveal the meaning of industrial culture and place attachment of local inhabitants of Chemnitz. The central argument of the article is that industrial culture is usually understood in a historicizing and aestheticizing way, fuelled by the possibilities to valorise the legacies of the age of industrialization and its persistent artefacts and structures for marketing or musealization purposes. This frequently observable urban strategy neglects the memories, experiences and emotions of local inhabitants, and thus fails to support positive identification processes with connection to the industrial past of a specific place. This paper elaborates a conceptual definition of industrial culture as a complex approach with tangible and intangible dimensions, various temporal layers and multiple, sometimes controversial narratives. It discusses the role of industrial culture for regional and local image building and place related identity formation and demonstrates – reporting from an empirical experiment–, how individual counter-narratives can be detected, visualized and transferred and thus can increase reflexivity of society and support regional identity processes.

Published: June 2018

Abstract
Professional development in sustainable teacher education has recently shifted to focusing on pedagogical practice rather than theoretical knowledge. Given that, reflection practice can have an effective role in identifying undiscovered potentials of prospective language teachers. Hence, the current study was an attempt to examine the potential core qualities of Iranian prospective language teachers in a way to sustain professional development through merging theoretical knowledge and pedagogical practice. To that end, core reflection model, which is a concept in the context of sustainability, was practiced by ten prospective language teachers through drawing on their reflective journals, focus group discussions, and field notes collected over a four month period. Analysis of the obtained data revealed several core qualities on the three scales of feeling, thinking, and wanting. These qualities appeared to have been developed through interaction of both theoretical knowledge and pedagogical practice. This demonstrates the value of reflection practice as a way toward more development in making sense of teachers’ core qualities. Thus it can lead to positive changes in shaping teachers sustainable professional identity.
Blockchain and the Future of Digital Learning Credential Assessment and Management
Authors: Jirgensons Merija , Kapenieks Jānis 
Published: June 2018

Abstract
Blockchain educational technology has created assessment and management tools for learner credentials that are permanent, transparent and sustainable while giving users direct access. Personal encrypted credentials enable users to shape lifelong learning pathways and personalizes education according to individual values and needs. They allow for the permanent documentation of both formal and informal learning based on transversal competencies, adjustable across the economic sector and responsive to situational needs. Badging was the initial response to online credentialing. Mozilla’s open digital badges have become the unofficial global standard and the specifications remain free. They may be viewed in e-portfolios and social networks. Yet, if issuers cease hosting badges, they become invalid even when authentic. Some experiments with blockchain technology remedy this situation by creating a permanent, secure and sustainable infrastructure for learning records. The MIT Media Lab has produced the bitcoin based Blockcerts; whereas the Knowledge Institute, Open University, UK has developed Ethereum’s Smart Contracts to document Microcredentials (Badges). Both are Open Source products. Most EU nations are experimenting with educational blockchain. The technology creates an infrastructure to document, store and manage credentials and provides learners with a sustainable record of achievements they can control. It also benefits universities by reducing administrative costs and bureaucracy.
Education for Sustainable Development: The Choice of Pedagogical Approaches and Methods for the Implementation of Pedagogical Tasks in the Anthropocene Age

Published: June 2018

Abstract
Sustainable education and education for sustainable development (ESD) have witnessed a deserved number of research studies in the recent years. The present article proposes a holistic research framework for the research on sustainable education and education for sustainable development in the 21st century. The article aims to choose a more holistic research perspective by avoiding a piecemeal approach in education research. Moreover, it proposes some strategically important ideas about the use of approaches and methods for sustaining the generational readiness for sustainable development. The paper proposes a general framework for pedagogy and practice for ESD research which is open, holistic, strategic, sustainable, and integrated. A broader perspective has been developed as the relation of the ecological–cultural–social environment aspects seen in a broader adaptive evolutionary sense as a condition necessary for the development of a human species and the development of these conditions in the evolutionary process. The choice of a broader perspective is proposed by relating it to an observational study on Generation Z that many educators, social scientists and the populations have already started recognising as one of the participants in the intergenerational process. The phenomenon of Generation Z is new; its features have not fully revealed in their apparent form, yet. Furthermore, the generation has not reached its maturity yet, but the development of this phenomenon is inextricably related to the issue of generational commitment, which is also related to the evolutionary development. The observational study has been carried out by involving participants from VECC Daugavpils Vocational School. The evaluation of the participants’ real experience in a wider and broader framework has been used to draw strategic conclusions, which will help keep focus on the need to sustain generational readiness for sustainable development in the harmonisation of the choice of pedagogical approaches and methods.
