Authors:   Bashkir State Agrarian University, Khalitova Larisa Rafikovna
Published: February 2018

The paper analyzes the purchasing power of company and organization employees’ wages in the Republic of Bashkortostan. The research is based on available statistical data on foodstuffs consumption per capita in the Republic of Bashkortostan, changes in nominal wages and consumer prices. The effect of factors on the purchasing power of wages is considered. These factors are represented by twelve indicators which are directly related to their results. Assessing the influence of factors on the real wage index, the author selects the most significant indicators which are crucial in the correlation and regression model. Such foodstuffs as bread and bakery products made from wheat flour, ordinary vodka, whole milk, butter, and wheat flour have the greatest impact on the consumer purchasing power.

Authors: Villamayor Claudia
Published: February 2018

En el presente trabajo la autora plantea la necesidad de construir pensamiento alternativo de manera urgente e insurgente. Las epistemologías del sur, propone, podrían constituirse en alteridades permanentes y, al mismo tiempo, volverse vitales para cualquier lucha emancipatoria en la medida en la que se permita innovar en sus lógicas de producción intelectual y seamos capaces de producir procesos de comprensión. La autora también presenta algunos interrogantes como ¿qué  hacer ante la dominación instituida?, ¿solo deconstruir?, ¿algo así como volver sobre las huellas a partir de los relatos cientificistas? Y propone trabajar con categorías creativas de la mano de un pensamiento activo, de acción y objetivable.

Published: February 2018

Indonesia has high burden of multidrug-resistant tuberculosis (MDR-TB). Cartridge-based nucleic acid amplification test (CB-NAAT), which is recommended as a diagnostic method of MDR-TB by World Health Organization, is faster in achieving the result. This method determines MDR-TB only from the rifampisin resistance, by detecting mutations that occur on the 81 bp hot-spot region of the rpoB gene. The isoniazid resistance is not included in the determination of MDR-TB by this method. Hybridization-based NAAT (HB-NAAT) detects MDR-TB not only from the rifampisin resistance (codon 526 and 531 rpoB gene), but also from the isoniazid resistance (codon 315 katG gene). The aim of this study was to know the validity of the HB-NAAT in detecting MDR-TB using sputum with CB-NAAT as the gold standard in a diagnostic study. All of 51 sputums were collected during June 2013 from patients suspected pulmonary MDR-TB at Dr. Hasan Sadikin General Hospital. The result of CB-NAAT were 16 MDR-TB, 12 TB non MDR, and 23 non TB. HB-NAAT examination results were 3 MDR-TB, 25 TB non MDR (3 RMR, 6 IMR, 16 susceptible) and 23 non TB. The sensitivity of HB-NAAT was 18.75% and specificity 100%. Low sensitivity values may due to the high mutation variations in the samples. So it could not be detected only by codons 526 and 531 for rifampisin resistance. For the detection of isoniazid resistance, HB-NAAT have optimal primer at low concentrations and it also need more than katG genes to detect isoniazid resistance. Based on this study, it can be conclued, that HBNAAT has low sensitivity but high specificity in the detecting MDR-TB.

Elevated fibrinogen levels is related to the blood hyperviscosity, that causes low blood velocity. Non-contrast-enhanced transcranial Doppler (TCD) is used to evaluate blood flow from the cerebrovascular system. To know the relationship between fibrinogen levels and examination of TCD in acute ischemic stroke through evaluation. A cross sectional study was admitted from July 2012-Juny 2013. The researchers determined the differences between fibrinogen and TCD in the stroke group and control. The researchers examined the relationship between fibrinogen and TCD examination in the stroke group. The fibrinogenwas measured with Clauss method. The TCD was examined due to middle of the cerebral artery (MCA) and the Internal Carotid one Artery (ICA). The patients were diagnosed as ischemic stroke from head CT-scan. Statistical analyses employed the Independent T test, Anova test and Pearson correlation. The researchers had 24 patients and 24 controls that the Fibrinogen levels in stroke group is 549.16±104.84 mg/mL and in the control group is 385.64±16.80 mg/mL. The researchers examined MCA in the stroke as well as the control and found the mean velocity 43.12±21.03and 56.97±6.22 (p=0.05), the peak velocity 74.17±32.58 and 94.55±14.11 (p=0.05) end diastolic velocity 23.27±12.66 and 35.30±7.34 (p=0.00). In ICA, the stroke group and control and found the mean velocity 31.40±8.86 and 43.07±8.06 (p=0.00), thepeak velocity 54.99±11.50 and 75.04±16.04 (p=0.00) end diastolic velocity 18.23±7.67 and 25.64±5.24 (p=0.00). The correlation between fibrinogen and TCD in the stroke group was not significant on MCA and ICA, P>0.05. It can be concluded that the differences between fibrinogen levels and TCD in the stroke group and control are significant. But there is no correlation between the fibrinogen and TCD in the stroke group.

Published: February 2018

Introducción. Entre las estrategias afectivas como forma de afrontar estados afectivos vinculados al proceso de aprendizaje se incluyen aquellas orientadas al control de emociones y las enfocadas a la motivación; ambas influyen directa o indirectamente en el rendimiento. El objetivo de esta investigación fue diseñar un instrumento para medir las estrategias afectivas utilizadas por los estudiantes universitarios durante el proceso de aprendizaje coherente con el concepto de estrategia de tipo afectivo y con el modelo teórico presentado.Método. Un total de 487 estudiantes universitarios de distintas titulaciones respondieron a la Escala de Estrategias Afectivas de Aprendizaje y a la Escala de Competencia para aprender. Para la validación del instrumento se realizaron diferentes técnicas y análisis tales como juicio de expertos, análisis factorial confirmatorio, análisis de fiabilidad y correlaciones.Resultados. Se ha validado un instrumento de 37 item para medir las Estrategias Afectivas basado en un modelo teórico formado por cinco factores: Evitación de Esfuerzo, Imagen Social, Motivación Intrínseca, Control de Ansiedad Externo y Control de Ansiedad Interno. Todos los factores están correlacionados menos el factor Evitación de Esfuerzo que no se relaciona con Control de Ansiedad Interno y apenas se relaciona con Motivación. Es preciso seguir avanzando en el modelo y en el instrumento para mejorar el ajuste. Las correlaciones de esta escala de Estrategias Afectivas y sus dimensiones con la escala y con las dimensiones de la Competencia para Aprender avalan la validez de criterio del instrumento. Los datos confirman que la Motivación Intrínseca y el Control de Ansiedad correlacionan de forma positiva y moderada con la Autogestión del Aprendizaje, mientras que la Evitación del Esfuerzo no se relaciona con ninguna dimensión de la Competencia para Aprender.Conclusiones. Se propone incidir en el uso de estrategias afectivas adaptativas y sustituir, en la medida de lo posible, las estrategias negativas por alternativas más eficaces para aprender.
Educational assistance to improve reflective practice among student teachers
Authors: Mauri Teresa , Clarà Marc , Colomina Rosa , Onrubia Javier
Published: February 2018

Introduction. Recent educational research suggests that joint reflection can enhance student teachers’ reflections on their own practice if they have adequate tutor support. This study aims to identify and characterize the assistance offered by college tutors in situations of joint reflection and analyses their contribution to the development of students’ ability to reflect on their teaching practice. More specifically, we aim to identify the kind of tutor assistance that best helps students to develop their reflective capacity and to understand the situations they encounter during teaching practice.Method. The research uses a case-study design to analyse the process of joint reflection engaged in by two groups of student teachers (13 and 15 students) with the assistance of their university tutors over five weeks of a teaching practice module. Data in the form of video recordings were subjected to two kinds of analysis: interactivity analysis and content analysis, both with the aim of examining the assistance offered by tutors in relation to reflective practice.Results. Each tutor distributed assistance in a specific way, focusing on different characteristics of reflection and prioritizing intervention in particular dimensions of it. Differences were also observed in the type and amount of assistance offered in each dimension of reflection. The tutors also differed in the extent to which their assistance targeted those dimensions of most relevance for an in-depth understanding of teaching practice situations.Discussion and Conclusion. In general, the tutors appeared to be better at helping students to identify the factors involved in their teaching practice experiences than they were in aiding their understanding through the identification and analysis of the characteristic dilemmas involved in these situations.

Published: February 2018

Introduction. The self-regulation of motivation (SRM) is conceptualized as a metamotivational process that guides students’ efforts and persistence when performing tasks. This process regulates students’ behavior through strategies that are influenced by motivational beliefs. SRM allows students to motivate themselves and guides their behavior.Method. In this article we aim to analyze and identify factors that may contribute to students ´ motivation to learn. The Self-Regulation of Motivation for Learning Scales (SRMLS) is an inventory developed to assess the SRM process in two major dimensions: motivational beliefs and SRM strategies. In order to achieve our goals 550 students from 7th to 9th grades responded to SRMLS.Results. Self-efficacy expectations, task value and achievement goals are good predictors of self-regulation of motivation strategies.Conclusion. Results suggest that self-efficacy expectations, task value and achievement goals may be important in promoting student´s regulation of motivation for learning. Also, data analyses support the Self-Regulation of Motivation for Learning Scales’ construct and concurrent validities for use with this population. Future implications for research and education are discussed.

Entre Duas Modernidades: A Constituição da Persona e o Mercado
Authors: Fachin Luiz Edson
Published: February 2018

Partindo-se de uma análise crítica que arrosta a primeira modernidade – entendida como o legado eurocêntrico de um sistema patriarcal, codificado e arrimado em um Estado-Nação – a segunda modernidade – identificada em uma sociedade econômica regulada por leis próprias, na qual os direitos fundamentais deixaram o campo do debate da efetividade para consubstanciar um hiperconsumo das ideias destacadas da cidadania e da democracia –, buscar-se-á investigar como a complexidade do real e a mácula do aparente convivem sob uma Constituição dirigente, que proclama a emancipação do indivíduo e funda uma ordem pautada em princípios democraticamente erigidos. Com isso, pretende-se demonstrar que entre os significados da equidade, democracia e direitos humanos entroniza-se a compra e venda que tudo transforma em mercadoria, fazendo se premente a construção de um novo direito,pautado em novos códigos e novos discursos, estruturados em uma principiologia axiológica de índole constitucional.

A Exoneração Tributária e o Direito de Crédito nos Impostos Sobre Consumo
Authors: Prado Daniel Santos
Published: February 2018

O presente trabalho tem o objetivo de discutir, primeiramente, as concepções e princípios acerca do poder de tributar e como ele é aplicado no contexto dos impostos sobre consumo no Brasil, considerando o princípio da não cumulatividade. De acordo com o princípio da capacidade contributiva, devem ser concedidas exonerações tributárias para casos específicos. Por outro lado, existe o direito de crédito aolongo da cadeia produtiva para aqueles que são contribuintes de ICMS e IPI. Mas a legislaçãovigente não protege esse direito nos casos em que são garantidas isenções, por exemplo, e as consequências podem ser drásticas. Apesar de isso representar aumento na arrecadação, é, por outro lado, prejuízo para a sociedade, tanto para o consumidor como para o produtor.
