Published: December 2018

La Realidad Aumentada es una tecnología emergente que cada día tiene una mayor incidencia en la docencia. Junto a ella la tecnología móvil se dibujan como uno de los binomios más eficaces para apoyar un aprendizaje significativo y ubicuo. No obstante, para que este pueda funcionar con validez el estudiante debe encontrarse motivado para utilizarlos durante el proceso formativo. A través de la aplicación del modelo Instructional Material Motivational Survey de Keller (1983), se ha tratado de determinar el grado de motivación que el alumnado de Grado de Pedagogía de la Universidad de Sevilla tienen sobre la utilización en el aula de apuntes enriquecidos a través de Realidad Aumentada y disponibles mediante dispositivos móviles. Esta metodología, ha sido valorada de forma positiva por los alumnos participantes en este estudio. Además podemos señalar que el principal hallazgo logrado ha sido la alta relación entre la motivación de los alumnos para emplear los apuntes enriquecidos y el rendimiento en la materia que los emplea. Igualmente se ha constatado que la utilización de la Realidad Aumentada beneficia el proceso de aprendizaje.

Published: December 2018

RESUMENLa universidad debería formar estudiantes bien informados, dotados de sentido crítico y comprometidos con la transformación social desde una ética universal basada en la solidaridad y en el bien común. Sin embargo, en la universidad actual predomina una visión utilitarista de la formación. La asignatura Educación para la paz y la igualdad se imparte en los Grados de Educación Infantil y Educación Primaria de la Universidad de Valladolid. Su finalidad es contribuir a la formación de personas éticas y comprometidas. En este artículo se analizan la potencialidad y los logros de esa asignatura. Mediante un estudio de caso en el que se utilizan entrevistas, observación no participante, cuestionarios, análisis de documentos y análisis de producciones del alumnado de la asignatura, se evalúa la valoración por parte de los estudiantes y la influencia que ejerce en ellos, así como los aprendizajes que genera. Se constata una mayor sensibilización, una mejora en la comprensión de la realidad global y el descubrimiento de estrategias didácticas para trabajar la paz y la igualdad en la escuela, pero sigue existiendo una actitud pasiva en buena parte del alumnado. Se precisa una educación contra el conformismo y la indiferencia.Palabras Clave: Formación inicial, Compromiso ético, Estudio de caso, Modelos de universidad.ABSTRACTThe university should educate well-informed students, endowed with critical sense and committed to social transformation from a universal ethic based on solidarity and the common good. However, at the current university, a utilitarian vision of education predominates. The subject Education for peace and equality is been taught in the Degrees of Early Childhood Education and Primary Education at the University of Valladolid. Its purpose is contributing to educate ethical and committed people. This paper analyzes the potentiality and achievements of this subject. Through a case study using interviews, non-participant observation, questionnaires, analysis of documents and that of student productions for the subject, assessment made by the students and their influence on them are evaluated, as well as the learnings generated by it. There is a greater awareness, an improvement in the understanding of the globalreality and the discovery of didactic strategies to work for peace and equality at school, but a passive attitude remains in many of the students. An education against conformism and indifference is needed.Keywords: Initial formation, Ethical commitment, Case study, University models.
Association of the hormonal status parameters with the results of the cardiorespiratory exertion test in athletes
Authors: Megeryan S. D.
Published: December 2018

The aim of this study was to identify the specifics of the endocrine system functioning in males professionally involved in sports. We have observed 70 sportsmen and 70 students of the Maritime Academy. The check-up included the following procedures: the ultrasound examination of the thyroid gland, assessment of the hormonal status (measuring concentrations of prolactin, cortisol, thyroid stimulating hormone, free thyroxin, antibodies to thyroid peroxidase in the blood serum), complete blood count (assessment of the hemoglobin level), assessment of microelements in the blood serum (calcium and magnesium levels). The study has established that athletes have significantly higher concentrations of thyroid-stimulating hormone and lower concentrations of cortisol and free thyroxin, as compared to people not involved in sports. A positive correlation between the levels of cortisol, thyroid-stimulating hormone, free thyroxin and prolactin in the blood serum has been found in athletes. The high levels of thyroid-stimulating hormone and relatively low values of cortisol may be considered as indicators of a better athlete’s performance and a reflection of the optimal adaptation of the pituitary-thyroid and pituitary-adrenal systems to systematic high physical loads.

Published: December 2018

Presently, the improvement in the quality of life of patients who underwent a laparoscopic surgical repair of hiatus hernia and the absence of the gastroesophageal reflux disease (GERD) recurrence are the basic characteristics of the surgical treatment. In this connection, further perfection of the tactics and techniques of the surgical GERD treatment becomes an important problem of modern surgery.

Here, we present a comparative analysis of the remote results of the surgical treatment of 159 patients with GERD-complicated hiatus hernia. The patients were divided into two groups, depending on the technique of the performed endosurgical treatment. The first group consisted of patients operated via the standard laparoscopic Nissen fundoplication. In the second group, we included those patients who underwent surgical treatment using a modified procedure of Nissen fundoplication with the formation of a non-tension cuff (RF patent No. 2529415 of 27.09.2014).

Evaluation of the results, based on the survey questionnaires Gerd-Q, GSRS, SF-36 and the data of instrumental research methods, was performed 1 to 5 years post-treatment.

The treatment of the GERD-complicated hiatus hernia patients with application of the technique of forming a non-hanging fundoplication cuff shows the best long-term results: the incidence of the reflux syndrome and signs of hyperfunction of the fundoplication cuff is lower. The revealed differences coincide with the data of the Gerd-Q and GSRS questionnaires, as well as the life quality estimation by the SF-36 questionnaire. The developed techniques do not require application of sophisticated technical skills and re-equipment and may be recommended for the practical use in the everyday practice in surgical hospitals of all levels.

Significance of APTT as early predictor of bleeding in comparison to thrombocytopenia in dengue virus infection
Authors: B. T. Hamsa , S. V. Srinivasa , K. Prabhakar , A. Raveesha , A. G. Manoj
Published: December 2018

Background: Dengue is a systemic viral infection transmitted by mosquitoes such as Aedes aegypti or Aedes albopictus. Dengue Fever (DF) is characterized by fever, headache, muscle or joint pain, and rash. The spectrum of dengue virus infection spreads from an undifferentiated fever and dengue fever (DF) to dengue haemorrhagic fever (DHF) with shock. Factors responsible for bleeding manifestations in dengue are vasculopathy, thrombocytopenia, coagulopathy, and disseminated intravascular coagulation (DIC). Coagulopathy results in derangement of activated partial thromboplastin time (APTT) which is an indicator of impending bleeding risk.Methods: A prospective study was conducted from June to December in 2017 in R L Jalappa Hospital. Patients aged above 18 years with febrile thrombocytopenia who are positive for dengue virus serology (NS1Ag and/ or IgM) were included in the study. Serial daily monitoring of platelet count and analysis of APTT levels were done. APTT was considered abnormal if it was more than 33.8s. Patients were followed up for evidence of leaking and bleeding manifestations.Results: Out of 170 patients 28.1% patients had bleeding manifestations. Bleeding signs were seen on clinical examination in 52.37% of patients. capillary leak was found in the form of Pleural effusion in 35.3%, Ascites in 41.2% and Periorbital edema in 31.2% of patients. Elevated APTT levels were seen in 110(64.7%) patients. Among patients with abnormal APTT platelet transfusion was done in 78.9% of patients, and among those with normal APTT levels platelet transfusion was done in 21.1% of patients.Conclusions: Our study showed significant correlation between bleeding manifestations and prolonged APTT levels as well as thrombocytopenia with abnormal APTT levels. Study concluded that 21.1% of platelet transfusions could have been prevented considering prolonged APTT as a predictor of bleeding manifestation, thus saving the resources and reactions due to platelet concentrate transfusion.

Published: December 2018

Este trabalho tem como objetivos fazer a análise de pavimentos dimensionado por meio do método oficial do DNIT confrontando com do uso do software SisPavBR desenvolvido na UFRJ e também o software AASHTOWare Pavement, que carrega consigo o método de dimensionamento proposto pelo AASHTO ME, NCHRP 1-37A. Para isto, foi então feito uso da contagem de veículos realizados para BR116/RS; no entanto, foi necessário criar bandas de volume de tráfego (N), devido o método do DNIT não considerar o arranjo dos eixos como o SisPavBR e AASHTOWare fazem em suas avaliações. Foi realizado também o levantamento do custo executivo do km de pavimento dimensionado por cada método. Desta maneira, verificou-se que enquanto um pavimento dimensionado pelo DNIT necessita de uma espessura de revestimento de 12,5 cm, no SisPavBR a camada necessária é de 19,5 cm e a conforme a AASHTO 40 cm. Da mesma forma, o custo do pavimento foi mais elevado para o dimensionamento da AASHTO e do SisPavBR, em relação ao método oficial. Adicionalmente foi realizada a análise da vida de projeto do pavimento dimensionado pelo DNIT, o qual ficou bem abaixo do esperado em ambas as análises, chegando em um caso a durar apenas 2 meses. Fica patente a necessidade de discutir a evolução do método oficial para uma abordagem mais moderna e em sintonia com a Mecânica de Pavimentos.

What Constitutes an ‘Actionable Insight’ in Learning Analytics?
Authors: Jørnø Rasmus Leth , Gynther Karsten
Published: December 2018

The possibilities of Learning Analytics as a tool for empowering teachers and educators have created a steep interest in how to provide so-called actionable insights. However, the literature offers little in the way of defining or discussing what the term “actionable insight” means. This selective literature review provides a look into the use of the term in current literature. The review points to a dominant perspective in the literature that assumes the perspective of a rational actor, where actionable insights are treated as insights mined from data and subsequently acted upon. It also finds evidence of other perspectives and discusses the need for clarification of the term in order to establish a more precise and fruitful use of the term.
Scaling Effective Learning Strategies: Retrieval Practice and Long-Term Knowledge Retention in MOOCs
Authors: Davis Dan , Kizilcec René , Hauff Claudia , Houben Geert-Jan
Published: December 2018

Scientific evidence for effective learning strategies is primarily derived from studies conducted in controlled laboratory or classroom settings with homogeneous populations. Large-scale online learning environments such as MOOCs provide an opportunity to evaluate the efficacy of these learning strategies in an informal learning context with a diverse student population. Retrieval practice, a learning strategy focused on actively recalling information, is recognized as one of the most effective learning strategies in the literature. In this study, we evaluate the extent to which retrieval practice facilitates long-term knowledge retention among MOOC learners using an instructional intervention. We conducted a pre-registered randomized encouragement experiment to test how retrieval practice affects learning outcomes in a MOOC. We observed no effect on learning outcomes and high levels of treatment non-compliance. This suggests that even evidence-based strategies may not work "out of the box" in new learning contexts and require context-aware research on effective implementation approaches. We conducted a series of exploratory studies on the extent to which learners recall knowledge gained in MOOCs over the long term. To our surprise, passing and non-passing learners scored similarly on a knowledge post-test, and both retained approximately two-thirds of what they learned over the long term.
Exploratory versus Explanatory Visual Learning Analytics: Driving Teachers’ Attention through Educational Data Storytelling

Published: December 2018

From a human-centred computing perspective, supporting the interpretation of educational dashboards and visualizations by the people intended to use them exposes critical design challenges that may often be trivialized. Empirical evidence already shows that “usable” visualizations are not necessarily effective from an educational perspective. Since an educator’s interpretation of visualized data is essentially the construction of a narrative about student progress, in this paper, we propose the concept of “Educational Data Storytelling” as an approach for explaining student data by aligning educational visualizations with the intended learning design. We present a pilot study that explores the effectiveness of these data storytelling elements based on educator responses to prototypes by analyzing the kinds of stories they articulate, their eye-tracking behaviour, and their preferences after inspecting a series of student data visualizations. The dual purpose is to understand the contribution of each visual element for data storytelling, as well as the effectiveness of the enhancements when combined.
Using Temporal Analytics to Detect Inconsistencies Between Learning Design and Students’ Behaviours
Authors: Nguyen Quan , Huptych Michal , Rienties Bart
Published: December 2018

Extensive research in learning science has established the importance of time management in online learning. Recently, learning analytics (LA) has shed further lights on the temporal characteristics of learning by allowing researchers to capture authentic digital footprints of student learning behaviours. Nonetheless, students’ timing of engagement and its relation to learning design (LD) and academic performance have received limited attention. This study investigates to what extent students’ timing of engagement aligned with instructor learning design, and how engagement varied across different levels of performance. Our findings revealed a mismatch between how instructors designed for learning and how students study. In most weeks, students spent less time studying the assigned materials on the virtual learning environment (VLE) compared to the number of hours recommended by instructors. The timing of engagement also varied, from in advance to catching up patterns. High-performing students spent more time studying in advance, while low-performing students spent a higher proportion of their time on catching-up activities. By incorporating the pedagogical context into learning analytics, not only we can understand what, why, and when students engage, but also how their behaviours are influenced by the way instructors design for learning.

Stavropol region is well known zone of vegetable seed production from 70th years of last century. Development seed production of main vegetable crops is connected with using of new technologies. New technological methods and its influence on the seed yield formation and on the quality of carrot seeds have been investigated in this study. The objects of the study were seeds of carrot variety Marlinka and different technological methods, including in schemes of sowing. Methods and conditions of experiments have been written in details with scheme of experiment by the study influence of sowing schemes on the seed productivity of carrot plants variety Marlinka. Years of study (2015-2017) have been characterized as drought. Seedling capacity of seeds was very small (about of 30%). Sowing with seed drill Matermacc (by the scheme of sowing: 25+20x20x20x20x20+25 sm) ensured the seedling capacity needed for survive of plants after winter. Yield of seeds was in 4-6 time higher in variant with using seed drill Matermacc and scheme of sowing 25+20x20x20x20x20+25 sm, than in variants with traditional technologies. Mass of 1000 seeds was similar under different technologies and schemes of sowing. But seedling capacity was significantly decreased under traditional technologies and using seed drill SZ-5,4.

Authors: Sokolova D. V.
Published: December 2018

The article presents the results of ecological and geographical study of table beet samples of the VIR collection. The study was carried out between 2014 and 2016 in three stations located in different soil and climatic zones of the Russian Federation: in Leningrad, Moscow and Krasnodar regions. The main attention is paid to the interaction of the genotype and the environment, as the main reason for the considerable variability in the yield of table beet varieties when growing them in different ecological and geographical zones. Today the search and creation of an initial high-yielding and versatile material for breeding of adaptive beet varieties is one of the most important trends in the table beet breeding programs. The article describes the evaluation of the factors of time and place of cultivation on yield. The factors that make the greatest contribution in the formation of yield are identified. Significant variability in the yield of collection samples, depending on the cultivation zone, was noted. Samples for the intensive type of cultivation in different zones are identified. The variety of table beet for inclusion in breeding programs, as a source of adaptability and high yield is recommended. The variety of table beet «Perfected Detroid Dark Red» (Canada) is recommended for inclusion in breeding programs as a source of adaptability and high yield.
ANALYSIS OF MARKET: METHODOLOGICAL ASPECT
Authors: Shabanov T. Yu.
Published: December 2018

A methodology for analyzing the agricultural market has been proposed. The concept of the market model from the standpoint of the dynamic equilibrium of supply and demand is described, a technique based on variational deviations of trends is proposed. Approbation shows the practical usefulness of the results obtained in the analysis and management of the cabbage market. The interrelation between the gross volume and the price of cabbage is established, the gradient and nature of market equilibrium are revealed, and the perspective of the cabbage market in the Russian Federation is described. The proposed analysis methodology considers market modeling as a dynamic equilibrium mechanism of supply and demand, it is a method based on variational deviations of trends. Approbation confirms the practical utility of the results for analyzing and managing the cabbage market. In the course of testing, it was established that the amplitude of price fluctuations with the current increase in gross production characterizes the cabbage market as developing; the market offer of each thousand tons of cabbage can change the price by 0.1416 c.u./t; the cabbage market maximum is at the level of 258 c.u./t at gross harvest of 3,138 thousand tons of cabbage. For the modern stage of development of the cabbage market with increasing production volumes, a decrease in prices is typical. It is shown that there are market relations between gross volume and price of cabbage, market characteristics and equilibrium gradient, which determine the prospects of the Russian cabbage market. The description of the methodology and the presentation of the results of testing the methods of modeling the market perspectives allow us to make optimistic conclusions about the expansion of the scope of application of theoretical economics for practical activities. In this regard, the proposed methodology for analyzing the market (concept, methodology) may be of interest to practicing economists. Despite the simplicity and accessibility of the described methodology, there are a number of issues related to the error of statistical data and unaccounted factors that require further research.

Sprouts of agricultural crops seeds are considered to be functional food products with high content of antioxidants. Though seeds of Allium species plants are used in some countries as spices the possibilities of appropriate sprouts utilization have never been investigated so far. Evaluation of perennial and A. cepa seeds biofortification with selenium revealed high nutritional value of the resulting sprouts characterized not only by high selenium content exclusively in a form of selenomethyl selenocysteine (a natural anti carcinogen) but also with high levels of antioxidant activity and high polyphenol content. It was demonstrated that among seven studied representatives of Allium species Allium cepa variety Krasnoye krugevo and perennial onion Allium fistulosum give seeds sprouts with the highest levels of selenium (10500-11000 μg/kg d.w.), polyphenols (9.3-10.8 mg-eq GA/g d.w) and the largest values of antioxidant activity (14.7-17.1 mg-eq GA/g d.w.). Utilization of one g of dried seeds sprouts powder, fortified with selenium provides up to 15.7% of the adequate consumption level of selenium exclusively in a form of selenomethyl selenocysteine possessing powerful anti carcinogenic activity.

Expanding the VPE-qGM Environment Towards a Parallel Quantum Simulation of Quantum Processes Using GPUs
Authors: Maron Adriano , Reiser Renata , Pilla Mauricio , Yamin Adenauer
Published: December 2018

Quantum computing proposes quantum algorithms exponentially faster than their clas- sical analogues when executed by a quantum computer. As quantum computers are currently unavailable for general use, one approach for analyzing the behavior and re- sults of such algorithms is the simulation using classical computers. As this simulation is inefficient due to the exponential growth of the temporal and spatial complexities, solutions for these two problems are essential in order to increase the simulation capa- bilities of any simulator. This work proposes the development of a methodology defined by two main steps: the first consists of the sequential implementation of the abstractions corresponding to the Quantum Processes and Quantum Partial Processes defined in the qGM model for reduction in memory consumption related to multidimensional quantum transformations; the second is the parallel implementation of such abstractions allowing its execution on GPUs. The results obtained by this work embrace the sequential simu- lation of controlled transformations up to 24 qubits. In the parallel simulation approach, Hadamard gates up to 20 qubits were simulated with a speedup of ≈ 50× over an 8-core parallel simulation, which is a significant performance improvement in the VPE-qGM environment when compared with its previous limitations.
Dynamic Scheduling based on Particle Swarm Optimization for Cloud-based Scientific Experiments
Authors: Pacini Elina , Mateos Cristian , García Garino Carlos
Published: December 2018

Parameter Sweep Experiments (PSEs) allow scientists to perform simulations by running the same code with different input data, which results in many CPU-intensive jobs, and hence par- allel computing environments must be used. Within these, Infrastructure as a Service (IaaS) Clouds offer custom Virtual Machines (VM) that are launched in appropriate hosts available in a Cloud to handle such jobs. Then, correctly scheduling Cloud hosts is very important and thus efficient scheduling strategies to appropriately allocate VMs to physical resources must be devel- oped. Scheduling is however challenging due to its inherent NP-completeness. We describe and evaluate a Cloud scheduler based on Particle Swarm Optimization (PSO). The main performance metrics to study are the number of Cloud users that the scheduler is able to successfully serve, and the total number of created VMs, in online (non-batch) scheduling scenarios. Besides, the number of intra-Cloud network messages sent are evaluated. Simulated experiments performed using CloudSim and job data from real scientific problems show that our scheduler achieves better performance than schedulers based on Random assignment and Genetic Algorithms. We also study the performance when supplying or not job information to the schedulers, namely a qualitative indication of job length.

Published: December 2018

The performance of the many-core Tile64 versus the multi-core Xeon x86 architecture on bioinformatics has been compared. We have used the pairwise algorithm MC64-NW/SW that we have previously developed to align nucleic acid (DNA and RNA) and peptide (protein) sequences for the benchmarking, being an enhanced and parallel implementation of the Needleman-Wunsch and Smith-Waterman algorithms. We have ported the MC64-NW/SW (originally developed for the Tile64 processor), to the x86 architecture (Intel Xeon Quad Core and Intel i7 Quad Core processors) with excellent results. Hence, the evolution of the x86-based architectures towards coprocessors like the Xeon Phi should represent significant performance improvements for bioinformatics.

MODELS OF ECONOMIC DEVELOPMENT OF CENTRAL BLACK EARTH REGION
ESTATES IN THE LATE 19th – EARLY 20th CENTURY
Authors: ZHITIN Ruslan Magometovich
Published: December 2018

We examine the peculiarities of the economic activity of landlords in the late 19th and early 20th century. The origins of conservative approaches to the development of private estates are analyzed, the reasons that led some nobles to proceed to successful management are revealed. The urgency of work is determined by the importance of studying the most optimal forms of socio-economic modernization of the post-reform agricultural sector. An analysis of the published sources shows that the majority of owners turned to traditional methods of economic activity. A promising area was the transfer of land in rent. Evaluating the advantages of city life, they completely broke ties with rural life and moved to the cities. Only a small, economically active stratum of landowners, under new conditions, could create self-sufficient capitalist farms. They modernized the estates that belonged to them, introduced into the practice of administration progressive management methods, rationally using available economic resources. Analyzing the sources of rationalization of exemplary estates, we turned to the memoirs of A.A. Fet, A.N. Engelhardt, S.F. Sharapov. The success of modernization of estates, in their opinion, was associated with attention to specific aspects of the farms economy, the introduction of new production technologies, administrative activities rationalization.

O presente artigo problematiza a relação entre o desenvolvimento do Estado de Bem-Estar no Brasil e a corrupção, vistos a partir da transição de um paradigma desenvolvimentista para um modelo liberal. Buscou-se analisar, através de revisão de bibliografia, o modelo de Bem-Estar Social implantado na América Latina e suas particularidades, com posterior transformação na década de 80, quando adquire caráter eminentemente liberal e proporciona grande trânsito de agentes privados junto ao Estado, influenciando as relações de poder e no crescimento de prática corruptivas, visto que não se atentou para a devida regulamentação desse novo paradigma. Então, pondera-se que a sociedade almeja por novas políticas públicas que respaldem as relações entre público e privado, a fim de salvaguardar os direitos sociais fundamentais dos cidadãos, sendo essa nova agenda de combate à corrupção no Brasil iniciada com a Lei 12.846/13, mediante um novo marco pela efetividade no cumprimento da função social da empresa.

Este artigo demonstrou a relevância do Terceiro Setor na atualidade, que mesmo em um ambiente de crise, instaurada no Brasil a partir do ano 2010 por motivos financeiros, políticos e sociais, agravada pelos fenômenos da globalização e mundialização, continuou a se desenvolver conforme demonstraram os dados examinados. Assim, apontamos a importância deste segmento social para a construção da democracia brasileira, através da efetivação do princípio democrático, que possui tanto uma dimensão jurídica, quanto contrafactual. Comprovou-se ainda, que o Terceiro Setor representa, ao mesmo tempo os anseios e a pluralidade da sociedade hodierna, considerada doutrinariamente como líquida, cabendo-lhe incentivar o exercício do fundamento republicano da cidadania na busca por melhorias que são necessárias para a sociedade brasileira. Para tanto, foram utilizados os métodos de revisão bibliográfica e análise dos casos pertinentes, tanto da literatura nacional, quanto estrangeira, evidenciando-se que pelos prismas econômicos e jurídicos que a sociedade civil organizada deve agir como um instrumento de concretização dos direitos essenciais dos cidadãos e principalmente deve servir como uma fonte de evolução constante do ambiente democrático brasileiro.

A presente pesquisa tem por finalidade efetuar a análise da discussão que permeia o exercício da jurisdição em meio ao ativismo judicial dialógico, dentro da lógica aristotélica da separação dos poderes e do mecanismo de freios e contrapesos. Diante do dever de dar evidência ao primado do Estado Democrático de Direito e, dessa forma, garantir a efetivação dos direitos fundamentais, notadamente no que concerne aos direitos sociais, o estudo volta-se para delinear a necessidade de proteção do patrimônio histórico-cultural. Para tanto, analisa a dinâmica do diálogo entre os poderes, a fim de que sejam encontradas soluções de fomento para as políticas públicas culturais. Por meio do método dedutivo, parte da premissa de que a cultura é bem jurídico pertencente a toda a coletividade, sem que haja o descarte do indivíduo enquanto sujeito de direitos, parte de um todo unitário ao qual está destinada a conservação da identidade de um povo, para esta e as futuras gerações. Utilizou-se, nesse espeque, pesquisa qualitativa, recorrendo à doutrina nacional e estrangeira. A pesquisa, portanto, pretende acirrar o debate acerca da necessidade de dar prioridade às políticas públicas voltadas ao universo cultural, apontando que cabe ao Estado a tarefa precípua de proporcionar seu acesso de qualidade.

Published: December 2018

Este artigo promove um diálogo entre dois grupos sociais discriminados: as religiões de matriz africana e os defensores dos direitos dos animais, e os próprios animais que são vítimas da exploração institucionalizada dos pelos humanos. Por meio de uma pesquisa bibliográfica, esta pesquisa utiliza elementos da Antropologia Cultural, especificamente os fundamentos do multiculturalismo, e a partir de uma ética biocêntrica, promove um diálogo intercultural entre os fiéis das religiões de matriz africana e os animalistas. Partindo do pressuposto de que a cultura é dinâmica e que se relaciona com outras expressões culturais, agregando novos valores, este artigo analisa a possibilidade de ressemantização no ritual de culto aos orixás, no tocante ao sacrifício de animais, para atender à demanda de reconhecimento de dignidade ao animal e dos seus direitos fundamentais básicos.

A TEORIA JURÍDICA DE RONALD DWORKIN COMO EXPRESSÃO DE UMA TEORIA PRAGMÁTICA DO DIREITO
Authors: Pedron Flávio Quinaud , Ommati José Emílio
Published: December 2018

O presente texto pretende discutir se a teoria do Direito como Integridade, de Ronald Dworkin, pode ser caracterizada em alguma vertente daquilo que se denomina de perspectivas pragmáticas do Direito. De tal forma, pretende-se demonstrar que se pode estabelecer uma relação entre o pensamento de Dworkin e a postura desenvolvida por Wittgenstein em sua obra Investigações Filosóficas. Desta forma, quando o primeiro elabora uma crítica a teoria pragmática ele está se referindo antes a autores como Richard Rorty e Richard Posner, e não Donald Davidson e Ludwig Wittgenstein. Para tanto a pesquisa analisará reconstrutivamente o movimento do giro linguístico, quer sob o olhar do pragmatismo filosófico, quer sobre o olhar da hermenêutica filosófica, para identificar elementos de uma certa teoria pragmática na construção de Dworkin.
ECO-CIDADANIA EM LUIS ALBERTO WARAT: UM OLHAR PARA O FUTURO DOS REFUGIADOS AMBIENTAIS
Authors: Bertaso Joao Martins , Seger Franciele
Published: December 2018

A presente pesquisa versa sobre a eco-cidadania como possibilidade de enfrentar a crise ecológica e suas consequências, dentre as quais destaca-se a massa de refugiados ambientais, pessoas forçadas ao deslocamento devido à ocorrência de desastres naturais. Nesse sentido, objetiva-se descrever, por meio do método dedutivo, da técnica de pesquisa bibliográfica e do procedimento histórico, os desafios e violações sofridas pelos refugiados ambientais, já que lhes é negado reconhecimento e proteção jurídica internacional. A partir disso, estudar a eco-cidadania em Luis Alberto Warat, a qual envolve ecologia, cidadania, política e subjetividade, elementos que, interligados, são capazes de alterar o atual estilo de vida, restaurando a relação homem-natureza, a fim de assegurar um direito ao amanhã, que dê condições de existência a um futuro comum. A eco-cidadania visa o reconhecimento do Outro (ser humano e natureza) nas suas diferenças, valendo-se do amor como cuidado. Por isso, ela contribui tanto para a formação de um sujeito ecológico, que se torne consciente da necessidade de preservação do meio onde vive, como para o reconhecimento de pessoas excluídas como os refugiados ambientais.

Problem-solving is a high-level ability to find solution to a problem. In the problem-solving process, students have to identify and understand the problems, plan the solutions, execute the plans and review the resolution process. This ability is needed by students to produce meaningful knowledge. This article discusses the effect of virtual labs in physics learning toward student’s problem-solving abilities. The improvement of problem-solving skills was analyzed in each step of the solution process. This quasi-experimental study was conducted at three different senior high schools. There were 165 students participating in this study, all of whom were divided into three experimental groups and three control groups. The research instrument used was five to eight questions of essay test. The results showed that the problem-solving ability of the experimental group was higher than that of the control group at each school. The analysis of each problem-solving step showed that, in each school, the students' ability to identify and define the problem and also to establish goals and objectives show a similar result. Students have an excellent ability in identifying problem up to plan for problem-solving, whereas for the step of analyzing the choice of ideas and step to follow up of problem-solving overall still need to be improved. Students who are unable to complete a particular problem-solving step will not be able to complete the next step well.

Pragmatic competence plays a crucial role in EFL learners’ communicative competence. In order to communicate successfully and appropriately, the effective potential of using pragmatic competence cannot be disregarded. A number of studies have aimed to investigate its production, but how EFL learners acquire and use those production appropriately has not been fully explored. To fulfill this gap, this research article attempted to investigate the effect of the flipped classroom on pragmatic development focused on apology strategies. The participants were 22 English-major students in their third and fourth year of study. The study made use of an experimental design in which the participants were homogenized and taught by the flipped classroom instruction. The data collection was done by using a Discourse Completion Test (DCT) as pre-test and post-test. The findings revealed that the frequency of use in some categories of apology speech act set significantly differed between the two groups, but the overall number of frequency was not significantly different. In addition, the result from the paired sample t-test of the pre-test and post-test showed that the learners who were taught by the flipped classroom instruction used English apology more appropriate and accurate than the pre-test.
