Corporate Social Responsibility and Business Performance in Takaful Agencies: The Moderating Role of Objective Environment
Authors: Nazri Muhamad Azrin , Omar Nor Asiah , Aman Aini , Ayob Abu Hanifah , Ramli Nur Ainna
Published: October 2020

The previous research on the relationship between corporate social responsibility (CSR) and business performance produced mixed findings. Scholars exerted the mixed findings are largely influenced by several factors and contexts where different markets, type of companies, industries, and countries would show different results. On that basis, this study examines how the dimensions of objective environment influence the relationship between CSR dimensions and the business performance of Takaful agencies in Malaysia. Malaysia was chosen as the country because it is among the largest Takaful contributors in the world. Stakeholder and contingency theory are used to analyze the hypothetical relationship between the variables. Questionnaires were distributed to Takaful agency managers who operate their businesses in Kuala Lumpur, Putrajaya, and Selangor state. About 211 of them participated in this study. The empirical findings suggest that economic and ethical activities have a direct influence on Takaful agencies’ business performance. Further results imply that while environmental dynamism influences business performance directly, environmental complexity significantly moderates the relationship between legal, philanthropy, and business performance. This research considered only the direct effect of CSR activities and the moderating effect of environmental dimensions on business performance with only the agency managers’ perspective studied. It adds new insights to the CSR and Takaful literature by revealing the relationship between the dimensions of CSR and business performance in the Takaful context, and sheds light on how governing authorities and Takaful operators should implement the CSR strategy and activities to make the industry successful in Malaysia and around the world, as Takaful businesses are heading towards becoming a global industry.
An Improved Hybrid Highway Traffic Flow Prediction Model Based on Machine Learning
Authors: Wang Zhanzhong , Chu Ruijuan , Zhang Minghang , Wang Xiaochao , Luan Siliang
Published: October 2020

For intelligent transportation systems (ITSs), reliable and accurate real-time traffic flow prediction is an important step and a necessary prerequisite for alleviating traffic congestion and improving highway operation efficiency. In this paper, we propose an improved hybrid predicting model including two steps: decomposition and prediction to predict highway traffic flow. First, we adopted the complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) method to adaptively decompose the original nonlinear, nonstationary, and complex highway traffic flow data. Then, we used the improved weighted permutation entropy (IWPE) to obtain new reconstructed components. In the prediction step, we used the gray wolf optimizer (GWO) algorithm to optimize the least-squares support vector machine (LSSVM) prediction model established for each reconstruction component and integrate the prediction results of each subsequence to obtain the final prediction result. We experimentally validated the effectiveness of the proposed approach. The research results reveal that the proposed model is useful for predicting traffic flow and its changing trends and also allowing transportation officials to make more effective traffic decisions.
Women in Engineering: Almost No Gap at University but a Long Way to Go for Sustaining Careers
Authors: Jung Eunju , Kim Ja Young Eunice
Published: October 2020

Engineering is one of the career fields where women’s underrepresentation has been tenacious. In Korea, the government has made continuous efforts in the last decades to make a difference, yet the rate of women who pursue an engineering career pathway is still low. In this study, we analyzed 415 survey responses at a large private university in Korea to fulfill the aims of the current study: (1) to examine the gender difference on the 11 major- and career-related variables using t-test, (2) to test the adjusted social cognitive career theory (SCCT) model for the engineering undergraduate students’ intention to pursue an engineering career using path analysis. The independent t-test results revealed that the gender differences were found not in any major-related variable, but in three career-related variables, indicating the female students perceived their future career less vested than the male students. The path analysis results indicated that the adjusted SCCT model fitted to the data well and the relations among the variables were generally in the expected way with some exceptions. The highlighted implication is that removing systematic barriers and gender stereotype threats is as important as providing supports for gender equity in pursuing an engineering career.
Towards More Proactive Sustainable Human Resource Management Practices? A Study on Stress Due to the ICT-Mediated Integration of Work and Private Life
Authors: Palm Kristina , Bergman Ann , Rosengren Calle
Published: October 2020

This article discusses sustainability in Human Resource Management (HRM) in the blurred digital working life, focusing on the emotion of stress. Its empirical basis is an activity and emotion diary study conducted with 26 employees of three industrial companies in Sweden. Our results show that work and private life are integrated by digital activities and also by emotions. Due to the extensive use of digital devices, stress in the working sphere is not only connected with work, and stress in the private sphere is not only connected with private life. The study also shows that stress is often episodic and can end due to activities connected with both the trigger and non-trigger spheres. From a social sustainability perspective, this study suggests that HRM should gently extend employee consideration beyond the traditional temporal and spatial boundaries of work, i.e., also including private life when understanding work in the digital age.

Published: October 2020

The safety climate is becoming more and more important in the processes of subway operation safety management due to various accidents. The research objective of this study is to explore the effects of safety climate and personal factors on safety behavior in subway operation. First, a conceptual model is developed based on the literature review and expert experience. Then, data are collected from 352 workers in the Xuzhou subway operation company by questionnaire survey. Third, the structural equation model is employed to do model analysis based on SPSS and AMOS, and the final model is achieved through a serious of model tests and modification. At last, the quantitative effect of safety climate on worker’s safety behavior in subway operation is obtained and analyzed. The results show that the descending order of total influence effect of safety climate on safety behavior is safety attitude (0.36), safety communication (0.265), safety policy (0.238), safety education and training (0.1), management commitment (0.099), and safety participation (0.073), respectively. The total influence effects of mediator variables (safety awareness and safety ability) are 0.242 and 0.194, respectively. This study would be beneficial by offering recommendations in regard to worker’s safety behavior to raise the safety level in subway operation.
Glyphosate Resistance in Sonchus oleraceus and Alternative Herbicide Options for Its Control in Southeast Australia
Authors: Chauhan Bhagirath S. , Jha Prashant
Published: October 2020

Sonchus oleraceus is becoming a hard-to-control weed in Australian cropping systems, especially in glyphosate-tolerant cotton and during summer fallows. Several biotypes of this weed have developed resistance to glyphosate as a result of common management practices under conservation agriculture systems in the country. A series of pot experiments were conducted to evaluate the effect of temperature on glyphosate efficacy and performance of several post-emergence and pre-emergence herbicides on a glyphosate-resistant (GR) and a glyphosate-susceptible (GS) biotype of S. oleraceus. At low temperatures (19–24 °C), no plants of the GS biotype survived glyphosate application at 570 g/ha; however, in the high-temperature regime (28–30 °C), 83% of the plants survived this rate of glyphosate. Similarly, for the GR biotype, up to 58% of the plants survived at 2280 g/ha of glyphosate when applied during the high-temperature regime and no plants survived this rate during the low-temperature regime. A number of post-emergence herbicides were found to be effective for S. oleraceus control. However, herbicide application delayed to the six-leaf stage compared with the four-leaf stage reduced control, especially for bromoxynil and saflufenacil herbicides. Glufosinate and paraquat were the most effective herbicides for S. oleraceus control, resulting in no seedling survival for both biotypes. Isoxaflutole, pendimethalin or s-metolachlor efficacy was not reduced by the presence of crop residue, suggesting that these herbicides could be used to control S. oleraceus in conservation agriculture systems. The results of this study suggest that growers will need to reduce over-reliance on glyphosate for weed control in summer fallows and use alternative post-emergence herbicides.
A New Solution for City Distribution to Achieve Environmental Benefits within the Trend of Green Logistics: A Case Study in China
Authors: Bi Kexin , Yang Mengke , Zahid Latif , Zhou Xiaoguang
Published: October 2020

Green logistics has become a consensus and an important method to achieve sustainable development in industrial activities. However, the traditional direct distribution mode has high carbon emissions, an uncertain delivery time, and a low delivery efficiency. Uncoordinated resource allocations and unreasonable network layouts of terminal distributions have shackled green development within the express delivery industry. Considering the trend of green logistics, this study innovatively proposes a comprehensive and environmentally friendly mode for city distribution based on end crowdsourcing service stations (ECSSs). This study also adopts node centrality indices of complex network theory to evaluate the node importance of existing terminal distribution outlets. The comprehensive weights of the indices are obtained via the three-scale AHP (Analytic Hierarchy Process) and TOPSIS (Technology for Order Preference by Similarity to an Ideal Solution) methods to identify the candidate nodes for ECSSs. Finally, a location model is built to determine the optimal location to establish the ECSSs. A real-world case study was conducted to provide the location scheme of ECSSs in Beijing, China. Environmental benefits as well as economic and social benefits can be substantially achieved through the implementation of the new mode. The results show that carbon emissions can be reduced by 23.79–28.49% for the end of the distribution, 16.27–16.35% for the front-end, and approximately 17% for the entire distribution. Additionally, the loading rate of vans for the front-end of the distribution can be improved by 15.77%.
Land Degradation and Mitigation Policies in the Mediterranean Region: A Brief Commentary
Authors: Halbac-Cotoara-Zamfir Rares , Smiraglia Daniela , Quaranta Giovanni , Salvia Rosanna , Salvati Luca , Giménez-Morera Antonio
Published: October 2020

Land degradation is more evident where conditions of environmental vulnerability already exist because of arid climate and unsustainable forms of land exploitation. Consequently, semi-arid and dry areas have been identified as vulnerable land, requiring attention from both science and policy perspectives. In some regions, such as the Mediterranean region, land degradation is particularly intense, although there are no extreme ecological conditions. In these contexts, a wide range of formal and informal responses is necessary to face particularly complex and spatially differentiated territorial processes. However, the fit of responses has been demonstrated to be different over time and space according to the underlying socioeconomic context and the specific ecological conditions. The present commentary discusses this sort of “entropy” in the policy response to land degradation in Southern Europe, outlining the intrinsic complexity of human–nature dynamics at the base of such processes. Reflecting the need of differentiated regional strategies and more specific national measures to combat desertification, three policy frameworks (agro-environmental, economic, social) with an indirect impact on fighting land degradation have been considered, delineating the importance of policy assemblages. Finally, the importance of policy impact assessment methodologies was highlighted, focusing on the possible responses reinforcing a continental strategy against land degradation. By evidencing the role of participatory planning, developmental policies indirectly addressing land degradation reveal to be an important vector of more specific measures abating desertification risk, creating, in turn, a favorable context for direct interventions of mitigation or adaptation to climate change.
Modeling and Mapping of Soil Salinity and its Impact on Paddy Lands in Jaffna Peninsula, Sri Lanka
Authors: Gopalakrishnan Tharani , Kumar Lalit
Published: October 2020

Soil salinity is a major threat to land productivity, water resources and agriculture in coastal areas and arid and semi-arid regions of the world. This has a significantly negative effect on the land and causes desertification. Monitoring salt accumulation in the soil is crucial for the prevention of land degradation in such environments. This study attempted to estimate and map soil salinity in Jaffna Peninsula, a semi-arid region of Sri Lanka. A Partial Least Squares Regression (PLSR) model was constructed using Sentinel 2A satellite imagery and field-measured soil electrical conductivity (EC) values. The results showed that satisfactory prediction of the soil salinity could be made based on the PLSR model coupled with Sentinel 2A satellite imagery (R2 = 0.69, RMSE = 0.4830). Overall, 32.8% of the land and 45% of paddy lands in Jaffna Peninsula are affected by salt. The findings of this study indicate that PLSR is suitable for the soil salinity mapping, especially in semi-arid regions like Jaffna Peninsula. The results underpin the importance of building adaptive capacity and implementing suitable preventive strategies for sustainable land and agricultural management.

Since 2003, H5N1 highly pathogenic avian influenza viruses (HPAIV) have not only caused outbreaks in poultry but were also transmitted to humans with high mortality rates. Vaccination is an efficient and economical means of increasing immunity against infections to decrease the shedding of infectious agents in immunized animals and to reduce the probability of further infections. Subunit vaccines from plants are the focus of modern vaccine developments. In this study, plant-made hemagglutinin (H5) trimers were purified from transiently transformed N. benthamiana plants. All chickens immunized with purified H5 trimers were fully protected against the severe HPAIV H5N1 challenge. We further developed a proof-of-principle approach by using disulfide bonds, homoantiparallel peptides or homodimer proteins to combine H5 trimers leading to production of H5 oligomers. Mice vaccinated with crude leaf extracts containing H5 oligomers induced neutralizing antibodies better than those induced by crude leaf extracts containing trimers. As a major result, eleven out of twelve chickens (92%) immunized with adjuvanted H5 oligomer crude extracts were protected from lethal disease while nine out of twelve chickens (75%) vaccinated with adjuvanted H5 trimer crude extracts survived. The solid protective immune response achieved by immunization with crude extracts and the stability of the oligomers form the basis for the development of inexpensive protective veterinary vaccines.

Authors: Belova L.A. , Mashin V.V. , Sitnikova A.I. , Belov D.V.
Published: October 2020

The review presents the main risk factors for cerebral venous thrombosis (CVT). It outlines current understanding of their role in the pathogenesis of venous strokes. The purpose of the review is to systematize the CVT risk factors according to their effect on a particular component of the Virchow’s triad. Pubmed and eLIBRARY, as well as publications and papers on the issue were considered to be the main sources. As a rule, CVT is a multifactorial disease, which is more typical for young people, more often women. However, it can also occur in children and elderly patients. Since CVT does not always have a specific onset, knowledge of risk factors can help in the early disease diagnostics. In comparison with arterial thrombosis, CVT prognosis is generally more favorable. However, the consequences of the disease remain in 15–30 % of patients. The article presents the factors influencing CVT prognosis and outcome. It is considered, that such patients require timely detection and early diagnostics, as it will increase treatment efficacy, reduce after-effects and mortality. Keywords: cerebral venous thrombosis, risk factors, deep vein thrombosis, superficial vein thrombosis, venous stroke. В обзоре представлены основные факторы риска развития церебральных венозных тромбозов (ЦВТ). Обсуждаются современные представления о роли этих факторов в патогенезе венозных инсультов. Целью данного обзора является систематизация факторов риска ЦВТ в зависимости от влияния на тот или иной компонент триады Вирхова. В качестве источников информации использовались данные электронных библиотек Pubmed, eLIBRARY , а также публикации и статьи по данной проблеме. ЦВТ представляет собой, как правило, мультифакторное заболевание, более характерное для лиц молодого возраста, чаще женского пола, но также встречающееся у детей и пожилых пациентов. Поскольку ЦВТ не всегда имеет специфическое начало, знание факторов риска может помочь в ранней диагностике этого заболевания. Прогноз при ЦВТ, по сравнению с артериальным тромбозом, в целом более благоприятный. Однако у 15–30 % пациентов остаются последствия данного заболевания. В статье представлены факторы, влияющие на прогноз и исход ЦВТ. Постулируется, что указанная категория пациентов требует своевременного распознавания и ранней диагностики заболевания, что будет способствовать повышению эффективности лечения, уменьшению последствий патологии и снижению летальности. Ключевые слова: церебральный венозный тромбоз, факторы риска, тромбоз глубоких вен, тромбоз поверхностных вен, венозный инсульт.

Authors: Budnik Galina A. , Korolyova Tat’yana V. , Kotlova Tat’yana B.
Published: October 2020

The article studies the main problems of the power engineering of the front-line areas of the centre of Russia during World War II. The details of the evacuation of power plant equipment from the centre of the country to the Urals and Siberia, the organisation in the front-line zone of uninterrupted supply of electricity to the army and industrial enterprises, and the power plants recovery on the territory liberated from the enemy are shown. The problems and diffi culties in the work of labour collectives, such as providing power plants with fuel and workforce are pointed out. The main ways to overcome them are analysed. The novelty of the study lies in the fact that for the fi rst time an attempt is made for comprehensive, multi aspect study of the work of the branch in 1941-1945. The most important factors contributing to the organisation of the uninterrupted operation of energy facilities are elicited. Among them is a patriotic upsurge; the advantage of planned, policy-based methods for managing the industry; tightening, in accordance with the martial laws, labour legislation; the employment of prisoners of the Gulag of the NKVD of the USSR in the construction of power plants; achievements of scientists, inventors and innovators of production. The range of issues requiring further scientifi c study is determined.
DOMESTIC PROBLEMS OF RESIDENTS OF THE REAR REGIONS OF RUSSIA DURING WORLD WAR II
Authors: Volkova Yelena Yu. , Volkov Grigoriy Yu.
Published: October 2020

To create an objective picture of the achievement of Victory over the Axis powers, it is necessary to analyse the numerous everyday problems faced by workers of the rear regions of Russia. Preferring the analysis of certain aspects of everyday life (fi rewood harvesting, industrial goods production, public utilities, urban improvement), the authors briefl y considered the historiography of the problem. They showed that researchers began to pay attention to this question only from the beginning of the 1970s. Based on archival materials and the recollections of eyewitnesses, it is shown that the war sharply aggravated the already poorly developed sphere of life. Centralised market funds, local repair and construction facilities were reduced, and there was a shortage of qualifi ed personnel, fuel, transport, etc. On the other hand, the attention of the local leadership, especially in 1941-1942, was focused primarily on the mobilisation of all forces to repel the enemy. In 1943-1945, after increasing state allocations for social needs and fi nding ways out of the current critical situation, domestic problems eased somewhat. The authors come to the conclusion that not only the physical and psychological state of workers depended on solving everyday problems, but the main thing in war conditions was their desire to work for the sake of Victory. Throughout
the war, living conditions remained extremely diffi cult. There were objective and subjective reasons for this. In general, the solution of everyday problems depended on the initiative of the workers themselves, their creativity and resourcefulness.

Authors: Romero Bello Ezequiel , Gómez Morales Yakelín
Published: October 2020

La Educación Patrimonial se ocupa del patrimonio y de la formación de los individuos y las sociedades en función de su protección, conservación y uso sostenible. Es importante en la educación primaria la creación de espacios que la potencien y logren su pertinencia donde los escolares jueguen un papel protagónico y activo a partir de sus experiencias en el contacto directo con su entorno. Del trabajo que se desarrolle en función de lograr estos objetivos con aquellos bienes patrimoniales que atesora una ciudad, dependerá en gran medida su sostenibilidad en el tiempo para que sea aprovechada por las presentes y futuras generaciones como legado de las que las han antecedido. El artículo presenta los resultados de una investigación cuyo objetivo fue construir una metodología para el trabajo con la Educación Patrimonial de los escolares de esta enseñanza a través de talleres de Artes Plásticas que desarrollan los instructores de arte.

Emplea métodos y técnicas que permiten la obtención de la información a partir de la interacción del investigador en el propio campo. Desde lo teórico aporta la metodología, con un enfoque interdisciplinar y contextualizado en el entorno de la institución educativa. Como aporte práctico ofrece un sistema de acciones que se desarrollan por etapas y donde se utilizan bienes patrimoniales importantes de la localidad. Las transformaciones que se operan en el cuidado, conservación y sostenibilidad del patrimonio dan cuenta del valor científico de la metodología como propuesta de solución al problema declarado.
La pérdida de legitimidad de los partidos políticos argentinos
Authors: Sidicaro Ricardo
Published: October 2020

Para analizar las causas de la declinación de la legitimidad de los partidos políticos argentinos en el período de reconstrucción institucional abierto en 1983, este artículo se centra: 1) en el sentido de las acciones de los dirigentes políticos y 2) en las  transformaciones de las subjetividades de los ciudadanos. El análisis sostiene que en la medida que la vida política nacional de 1930-1983 se caracterizó por la violación casi permanente de las reglas democráticas, los dirigentes políticos adquirieron estilos de acción que luego obstaculizaron la construcción de un sistema democrático moderno. Desde 1983, en la sociedad, las combinaciones entre reclamos antimilitaristas y demandas democráticas produjeron muchas expectativas que luego se frustraron. Por otra parte,  el debilitamiento de la cohesión social y la mayor libertad cultural aumentaron los niveles de exigencias políticas de los ciudadanos y sus críticas a los partidos políticos.
Las políticas sensibles al género: variedades conceptuales y desafíos de intervención
Authors: Rodríguez Gustá Ana Laura
Published: October 2020

Este artículo repasa algunas de las principales características de las políticas orientadas a instaurar una mayor igualdad de género, discutiendo, en líneas generales, cuatro grandes categorías identifcadas en la literatura: a) las políticas de acción afrmativa, b) las políticas para las mujeres, c) las políticas con perspectiva de género y, finalmente, d) las políticas de  transversalización de género –conocidas por su término en inglés, gender mainstreaming–. Dichas políticas difieren en sus enfoques teóricos y en sus metodologías de intervención. Además, este artículo discute sus efectos imprevistos e inesperados. A modo de conclusión, examinamos qué aspectos de cada una de estas líneas de acción podrían combinarse en una plataforma de políticas mayor en aras de promover intervenciones estatales capaces de instaurar un Estado democrático de género.

La dialéctica de la exclusión y de la inclusión en las sociedades democráticas
Authors: Yannuzzi María de los Ángeles
Published: October 2020

Las sociedades democráticas han insertado en su seno las múltiples diferencias que el liberalismo mantuvo neutralizadas en una esferano-política. Pero esta inclusión presenta problemas. Primero, porque se trata de sociedades altamente conflictivas. Al pensarse las diferencias en términos de igualdad, se dificulta, particularmente en los casos de diferencias insolubles, la conformación de criterios compartidos para unaestrategia pacífica de resolución de conflictos. Segundo, porque la política democrática se basa en el consenso, por lo que se busca alguna forma de homogeneización que excluya aquellas diferencias atentatorias de la unidad. Vemos así que el relativismo que caracteriza en su base a toda democracia no hace más que cuestionar la constitución de universales a partir de los cuales pensar la política. Esta paradoja constituye uno de los mayores riesgos que se deben enfrentar, ya que según como se la resuelva será la dinámica de exclusión e inclusión.

Impacto de las nuevas normativas electorales en Argentina. Discusión y análisis de la Ley de Reforma Política 26.571
Authors: Gallo Adriana
Published: October 2020

En el presente trabajo se analiza la Ley de Democratización de la Representación Política,la Transparencia y la Equidad Electoral, sancionada a fies de 2009 en nuestro país; poniendoparticular énfasis en la normativa de primarias abiertas, simultáneas y obligatorias (PASO), iniciativa inspirada en el modelo de Uruguay, donde se aplica una regla que obliga a todos los partidos registrados ofiialmente a celebrar internas abiertas simultáneas, reguladas por el organismo electoral del país.Aquí consideramos que el principal inconveniente de la reciente reforma radica en que se quiere ordenar al sistema utilizando el criterio partidario como elemento organizador, peropartiendo de principios contradictorios, sustentados sobre visiones antagónicas respecto de los partidos políticos; lo cual difiulta una consideración apropiada de los mismos, tanto en loreferente a su estructura interna como a su posición y comportamiento en el marco general de las instituciones democráticas. En este contexto, se verá que cuando se pauta un tipo de competencia despartidizada, sectorial y personalizada, y se recurre a la totalidad de la ciudadanía para que se expida en ella, se termina promoviendo la fragmentación, la inconsistencia interna y la pérdida de relevancia de los partidos políticos en la escena electoral.

Estado y servicios públicos en la posconvertibilidad (2003-2015): ¿qué hubo de nuevo en la participación estatal?
Authors: Pérez Verónica , Rocca Mariela Verónica
Published: October 2020

En el año 2003 se abrió un nuevo ciclo político en Argentina que implicó profundas transformaciones respecto de la década precedente. Entre ellas se destacó un replanteo de las relacionesdel Estado con las empresas privatizadas. El presente trabajo aborda el accionar del Estado en los servicios públicos durante el período 2003-2015, estudiando comparativamente dos servicios del Área Metropolitana de Buenos Aires que fueron re-estatizados en esa etapa: el de agua potable y saneamiento y el de transporte ferroviario de pasajeros. En dicho contexto, planteamos los siguientes interrogantes: ¿Cuál fue la lógica de las re-estatizaciones? ¿Qué tipo de institucionalidad se forjó en relación con este cambio en la gestión de dichos servicios? Para el desarrollo de las hipótesis propuestas se analizaron articuladamente diversas fuentes primarias y secundarias y fueron puestos en relación con estudios específicos sobre la temática.

Authors: GAYTÁN-LARA Francisco Javier , ZÁRRAGA–NUÑEZ Ramón , GALINDO-GONZÁLEZ Rosario
Published: October 2020

The creation of films formed by the incorporation of ZnO or TiO2 in poly(methylmethacrylate) PMMA matrices was proposed in order to improve their properties as resistance to high temperatures. ZnO and TiO2 nanoparticles were synthesized by the sol-gel method, which does not require the use of surfactants and is easily scalable. In the present work, zinc oxide (ZnO) or titanium oxide (TiO2) incorporations were carried out in a polymeric matrix of Poly(methylmethacrylate) PMMA. Both oxides were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction spectroscopy (XRD) and diffuse reflectance UV-Vis spectroscopy. PMMA was obtained by the suspension free radical polymerization method and PMMA composites containing ZnO or TiO2 were obtained. Polymer characterization was performed using Fourier transform infrared spectroscopy (FTIR). The composites were analyzed by thermogravimetric analysis (TGA) and its thermal resistance was found to be the best incorporation of TiO2 in 1%.
Analysis of significant learning in the flipped classroom: a conceptual cartography
Authors: ESCUDERO-NAHÓN Alexandro , MERCADO-LÓPEZ Emma Patricia
Published: October 2020

The Flipped Classroom is an educational model that asks students to study educational content at home and come to the classroom for learning activities. This promotes meaningful learning with the help of digital technologies. The aim this documentary research was to analyze the relationship between the Flipped Classroom and learning meaningful, through Conceptual Cartography, in order to propose an evaluation model for Flipped Classroom. To achieve this, the documentary research method called Conceptual Cartography was applied, which is developed in four phases: The findings suggest that, theoretically, there is a direct relationship between the Flipped Classroom and meaningful learning. This relationship is based on the theoretical principles of constructivism. However, there are no specific instructional designs for the Flipped Classroom and, so far, the evaluation of the Flipped Classroom has focused on students' perception of the model and not on their significant learning. In conclusion, although the Flipped Classroom does easily admit constructivist theoretical foundations when promoting meaningful learning, this relationship has not been reflected in its own instructional designs, nor in properly constructivist evaluation models.
Sports education an element of academic development

Published: October 2020

Sport is regularly seen as one of the forms of activation of the body that provide motor skills and contribute to healthy health, however it is important to appreciate it from the point of view of knowledge, so its contribution in aspects of academic competencies in students was analyzed upper middle level. In the first part, the history of sport was discussed, as well as the contributions of authors about educational sport and the learning generated. Subsequently, a comparison was made in young upper-middle-level students divided into two groups: the experiential group (they practice and perform exercise, sport and physical activity) and the control group (individuals who are totally sedentary), in order to observe performance. in school performance, class participation, decision making as well as knowing how influential or manipulable their peers can be to analyze and solve problems, in the study a questionnaire was applied to both groups using the Likert scale to know these results. The information obtained shows the positive influence that sport has on the development of educational capacities in students.

Mexico concentrates the marginalization in the southeastern states, to counteract this problem the federal government implemented several universal social programs, including Prospera. This research analyzes the impact generated among the beneficiaries of the Prospera Program based on income from work, and the variables of education, health, food security, both at the state level in Veracruz and Oaxaca and in the Istmo region that integrate both states. The Propensity Score Matching method was used to assess the impacts on labor inclusion that have those who receive the program, in contrast, with those who do not receive federal support. In addition, through the Analysis of Main Components, we related the productive and marginalization variables to find the characteristics of the study population. The results show that the Prospera program does not have a significant impact on the per capita income of the head of household. However, quintiles two and five have greater negative effects for the population from the Istmo. It is essential to revalue the Prospera Program strategy and incorporate more rigorous administration to have a positive impact for the rural population dedicated to agricultural activities.

The processes of educational and curricular innovation have been presented in recent decades within the Higher Education Institutions in a remarkable way by the emergence of new policies by the governments in charge, as well as by the various social movements that have promoted improvements in the processes of student learning. However, the accelerated work that has been done to incorporate change into education systems has left two issues unresolved, on the one hand, the careful and in-depth analysis of the concept of innovation and on the other, the way in which academics incorporate change into practice both in classroom and in academic management. The purpose of this research is to make progress in these two aspects, and to do so, it addresses innovation from the perspective of globalization and identifies academics as factors of change.

Current messaging applications communicate users through the use of the Internet, in their absence, they cannot operate. Gmail and WhatsApp are the main means that the students of the campus of the Polytechnic University of the State of Morelos (Upemor), use to communicate within the facilities of the university. However, when the Internet of the campus tends to fail, network users cannot use these applications and as a consequence student have to resort to rudimentary methods to transfer files or text messages. A possible solution to this problem is the use of the network infrastructure already available by the Polytechnic University of the State of Morelos, added to a system that allows the transfer and sending of messages and files through a local area network. During the present, the development of this system, its implications and its pros and cons will be described.

In this work, the reactive compatibilization of Polylactic Acid/Thermoplastic Starch (PLA/TPS, 80/20% w/w) blends using acrylic copolymers of methyl methacrylate-glycidyl methacrylate (MMA-GMA) was examined. The compatibilization was studied using torque rheometry, thermal analysis (DSC), Scanning Electron Microscopy (SEM) and mechanical properties. During melt mixing, the torque of PLA/TPS blends decreased, this was related to the breakup of starch chains. The addition of MMA-GMA copolymer increased the torque during the mixing period. This torque increasing is evidence of a viscosity increase and it was related to the reactions between the epoxy group present in the acrylic copolymer, the end-groups of the PLA and TPS hydroxyl groups. The morphologies of the compatibilized blends showed a decrease in the particle size of the TPS domains and an increase in elongation of 30%. The reactive compatibilization is an interesting technique to expand the property range of PLA materials, which can potentially substitute oil-based materials.

Published: October 2020

In this work, the process for the formulation of flexible polyurethane foam is presented following a design of experiments for mixtures. The proportion of polyol, diisocyanate, and crosslinker was considered as factors. The response variables considered were foaming time and reaction temperature. The result of the experiments showed that there is an area where the foam formulation is better. This zone is closed with 5% crosslinker, 50% polyol, and 45% diisocyanate, in this formulation denser foams with more uniform bubbles were obtained
