Moral Behavior in the Locker Room Predicts Perceptions of Task Cohesion in Youth Ice Hockey Player
Authors: Graupensperger Scott A. , Tisak Marie S. 
Published: January 2019

Abstract
Task cohesion (i.e., perceptions of team unity towards a task goal and positive feelings towards one’s own involvement) is associated with myriad psychosocial benefits for youth athletes. Accordingly, sport researchers and youth sport stakeholders are interested in ways of fostering task cohesion. Recent work has found evidence that prosocial and antisocial behaviors among teammates are associated with athletes’ perceptions of task cohesion; however, this research has been limited to moral behavior that takes place during gameplay. Despite youth sport experiences extending well beyond practices and games, we know very little about how moral behavior between teammates, in settings outside gameplay, relates to perceptions of task cohesion. To address this knowledge gap, the current study investigated whether prosocial and antisocial behaviors in the locker room setting were associated with perceptions of task cohesion in a sample of 238 youth male ice hockey players (Mage = 10.75). Using hierarchical regression analyses, our results revealed that (a) perceptions of peer prosocial behavior was positively associated with task cohesion, (b) perceptions of peer antisocial behavior was negatively associated with task cohesion, and (c) self-reported perceptions of participants’ own moral behavior was not significantly associated with task cohesion. Given the association with perceptions of task cohesion, these findings underline the value in promoting prosocial behavior and reducing antisocial behavior in sport settings outside gameplay and hold multiple theoretical and practical implications. Notably, moral behavior that takes place outside gameplay settings may be related to perceptions of task cohesion that primarily relates to goals and interactions during gameplay.
No Modification in Blood Lipoprotein Concentration but Changes in Body Composition After 4 Weeks of Low Carbohydrate Diet (LCD) Followed by 7 Days of Carbohydrate Loading in Basketball Players

Abstract
Recently, low carbohydrate diets have become very popular due to their numerous health benefits. Unfortunately, little is known about their chronic effects on the blood lipid profile and other cardiovascular disease risk factors in athletic populations. We compared the results of a four week, well-planned low carbohydrate diet (LCD) followed by seven days of carbohydrate loading (Carbo-L) on fasting lipids - triacylglycerol’s (TAG), LDL-C, HDL-C, total cholesterol (TCh), glucose, insulin and HOMA-IR levels in 11 competitive basketball players. During the experiment, we also measured body mass (BM) and body composition changes: body fat (BF), % of body fat (PBF), and fat free mass (FFM). Both diet procedures significantly changed the fasting serum concentration of TAG (p < 0.05) and body fat content (kg and %) (p < 0.05), without negative changes in FFM. The Carbo-L procedure increased (p < 0.05) fasting glucose levels significantly. A LCD may be suggested for athletes who want to reduce body mass and fat content without compromising muscle mass. Several weeks on a LCD does not change the lipoprotein - LDL-C and HDL-C level significantly, while a seven-day Carb-L procedure may increase body fat content and fasting glucose concentration. Such dietary procedures are recommended for team sport athletes to reduce fat mass, lipid profile disorders and insulin resistance.
Securitization of the Migration Crisis and Islamophobic Rhetoric: The 2016 Slovak Parliamentary Elections as a Case Study
Authors: Zvada Ľubomír 
Published: January 2019

Abstract
This paper focuses on the migration crisis from the perspective of Slovakia while examining the impact of the crisis on the last parliamentary elections in 2016. The migration/refugee crisis that started in 2015 played a significant role during the pre-electoral discourse and political campaigns. This paper has two main goals. The primarily goal is to apply the theory of securitization as proposed by the Copenhagen Peace Research Institute on the case study of Slovakia, and the secondary goal is to analyze the 2016 Slovak general elections. In here, I describe the securitization processes, actors, and other components of the case. Subsequently, I focus on a key element of this theory that is linked to the speech act. I evaluate Islamophobia manifestations in speech act and political manifesto of Slovak political parties. My source base includes the rhetoric of nationalist political parties such as Direction-SD (Smer-SD), Slovak National Party (Slovenská národná strana), We Are Family-Boris Kollár (Sme Rodina-Boris Kollár), and Kotleba-People’ Party Our Slovakia (Kotleba-Ľudová strana Naše Slovensko), all of which often apply anti-Muslim and anti-Islam rhetoric.
El laboratorio de física. Un colosal espacio interactivo en la Universidad Surcolombiana
Authors: Avendaño Alvaro 
Published: January 2019

1. ORIGEN Y DESARROLLO DEL LABORATORIO DE FISICA DE LA USCO
Tuvo su origen hace un poco mas de 23 años en las cabinas de curiosidades y en las colecciones de las empresas científicas alemanas de la antigua RDA especializadas en ese entonces, según parece en material para lo que hoy se llama secundaria. Estas colecciones llegaron en forma copiosa durante el nacimiento y de ellas empezaron a emerger lo que hoy es nuestro flamante laboratorio de física.Cuando se diseñaron los laboratorios de física se pensó en servir a la ciencia y a la industria regional. Pero lo que nunca se sospechó es que fueran a caer dentro de la categoría de museo de la historia de la física, donde se preservan desde viejos objetos como las antiguas guías de laboratorio que todavía se usan no por que hayan sido importantes para el desarrollo de la física en el Huila, sino porque no ha sido posible cambiar los montajes, los cuales muestran los principios no de la física, sino los principios de siglo.
La nueva normatividad en la formación de educadores: una invitación a la responsabilidad y a la excelencia académica
Authors: López Jiménez Nelson Ernesto 
Published: January 2019

Interesante y significativa resulta para la comunidad educativa del país la dinámica que se viene gestando en las instituciones formadoras de docentes (Escuelas Normales Superiores y Facultades de Educación) como consecuencia de las recientes normas expedidas en materia de reestructuración y replanteamiento del quehacer cotidiano de estas instituciones.
Los referentes normativos de este artículo permiten asumir una posición reflexiva y crítica frente a la actual situación por la que atraviesan estas instituciones, en donde es preciso resaltar la conveniencia de estas normas para evitar que las instituciones sigan solazándose en un río impresionante de argumentos derivados de la actitud polisémica generada de la percepción discutible de la autonomía institucional y universitaria, promoviendo un proceso de introspección académico sincero y responsable sobre la situación real actual de estas instituciones, que no nos exige mayor profundidad para afirmar el estado de crisis en el cual se debaten.
Procesos de participación y democratización de la facultad de educación
Authors: Ramírez Ofelia , Gutiérrez Hernando 
Published: January 2019

En el año de 1991 se intentó en nuestro país un pacto social con el fin de modernizar el Estado y adecuarlo a las expectativas de una nueva sociedad dentro de la cual se le diera mayor participación a sus miembros en la formulación de las políticas que lo rigen, al igual que garantizar una acción permanente de control y fiscalización de los diferentes procesos que se adelanten a través de los múltiples organismos que lo conforman y, tal vez lo más importante, dejar abierta la posibilidad de reformarlo y/o reestructurarlo.Todo este esfuerzo se orientaba a buscar un ambiente propicio para la convivencia pacífica dentro de un Estado que garantizara, a través de la racionalidad de sus instituciones jurídico-políticas, la equilibración de las relaciones sociales entre sus miembros y propiciara mecanismos para unas condiciones materiales de existencia dignas de seres humanos.

I. UNA CONTRADICCIÓN FUNDAMENTAL
1. Una contradicción del pensamiento occidental
De mi parte, he considerado siempre esta divergencia de puntos de vista manifestados como el corte más neto de la tradición intelectual europea. De un lado, el pensamiento europeo ha dado nacimiento a la ciencia y por tanto al determinismo y, de otro lado, él comprende tan bien al humanismo, quien lleva sobretodo a las ideas de responsabilidad y creatividad.Esta diferencia de puntos de vista es hoy mas fuerte que nunca. Un artículo de la revista “Scientific American” , consagrada a la vida en el universo, insiste en la evolución, en la Historia. Los físicos, opuestamente, evocan el determinismo, las leyes de Newton y la reversibilidad de éstas.
El paradigma sistémico-cibernético en la explicación cognitiva
Authors: Gooding L. Piedad 
Published: January 2019

En el siglo pasado el pensamiento científico estaba centrado en la masa, en la energía y en su conservación. El paradigma rector era la teoría de la termodinámica y su segundo principio , que indica que los sucesos tienden a generar en los sistemas estados de desorden máximo (entropía). La metodología vigente estaba regida por los principios de análisis, sumación, reactividad y mecanicidad, pues en términos generales la organización de los entes físicos (cuya ciencia, la física, era el modelo a reproducir en otras) resulta de la unión o sumación de elementos preexistentes.En 1948, Shannon sugiere la posible relación entre entropía e información y establece una analogía formal entre ellas: asi como la entropía es una medida de la desorganización, la información es una medida de la organización.Para Wiener, fundador de la Cibernética, el universo en su conjunto y los sistemas cerrados que contiene, tiende a degradarse y a pasar de un estado de organización y diferenciación a otros de caos y uniformidad.Sin embargo, existen a su interior enclaves locales cuya dirección aparece opuesta como un todo. En ellos existe una tendencia temporal y limitada a aumentar la complejidad de su organización; la vida se afirma y expresa en alguno de estos. Es aquí donde se origina y toma sentido la explicación cibernética.

LA CAPACIDAD NARRATIVA
Todos nuestros alumnos pertenecen a entornos particulares que son bastante complejos. Están compuestos por elementos culturales, sociales, históricos, físicos, etc. Estos entornos se ven transformados cuando los estudiantes migran o cuando sin migrar se presentan cambios geográficos, culturales, sociales. En consecuencia se debe aceptar que los entornos evolucionan. Esta evolución se da porque a su interior se dan transformaciones de los elementos que las componen, como de las relaciones que entre éstos y con otros entornos se presenten.Tales cambios pueden ser provocados por factores internos o externos. Es el caso del fenómeno del Niño que ha provocado, en nuestras localidades, transformaciones hidrológicas (disminución o aumento de los cauces de agua), sociales (formas de vestir,períodos de veraneo), etc.

Modelling of Fibrillation Induced Selective Cytotoxicity of Phenol Soluble Modulin α3
Authors: Das Mitradip , Dash Sandeep , Bhargava B. L. 
Published: January 2019

Phenol soluble modulin (PSM) α3, the most toxic member of α-toxin in Staphylococcus aureus bacteria, has been recently found to form cross-α amyloid fibrils and is selectively toxic to the mammalian cell membranes. In this work, it has been discovered that hydrophobic interactions play a major role in fibril formation of PSM-α3 strands, withstabilization energy of 28.7 kCal/mol. We considered two model bilayers mimicking mammalian and bacterial cell membranes, and found that single α-helix strand penetration is energetically unfavourable in both of them. Hence, we propose a simple model using energetics to understand the reason for selective toxicity of the peptide to the mammalian cell membrane. This study, besides enhancing the understanding of PSM-α3, can also act as a stepping stone in future drug development against ​S. aureus. ​
Sobre a Noção Categorial de Proto-topos
Authors: De Souza Edelcio Gonçalves 
Published: January 2019

O objetivo da presente trabalho é mostrar como é possível fazer semântica para linguagens proposicionais em ambientes categoriais que não sejam topos. Proponho a definição de dois tipos de categorias denominadas categorias com morfismos verdade (CTM) e proto-topos. Em categorias com morfismos verdade, pode-se definir as “funções de verdade” que correspondem aos conectivos lógicos de negação, conjunção, implicação e disjunção. Em proto-topos, pode-se mostrar que as “funções de verdade” assim definidas satisfazem certas propriedades desejáveis com respeito aos valores de verdade verdadeiro e falso.
Uma Crítica Popperiana ao Raciocínio Sociológico de Jean-Claude Passeron
Authors: Tarbes Sergio 
Published: January 2019

No livro "O Raciocínio Sociológico: o espaço não popperiano do raciocínio natural", o sociólogo francês Jean-Claude Passeron afirma que a utilização estrutural de linguagem natural nas ciências sociais cria o que denomina “raciocínio sociológico”, um método baseado no raciocínio natural onde não seriam possíveis a “demarcação” e “falseabilidade” de Popper e os “paradigmas” e a “ciência normal” de Kuhn. O presente artigo se propõe a analisar os fundamentos empíricos da afirmação de Passeron por meio de um método inspirado nas ideias de Karl Popper, consistente, no caso, na apresentação de exemplos empíricos que a contradigam. Os resultados permitem concluir que se existem dificuldades nas ciências sociais para a realização de experimentos e para a consolidação de paradigmas, tais dificuldades não podem ser atribuídas à utilização da linguagem natural.

Published: January 2019

Hybrid technologies are one of the directions of materials engineering development. They contribute to the subject of research on improving the performance of thermally sprayed steel coatings by thermo-chemical treatment. The paper presents the test results of arc spraying stainless steel coatings and then glow-discharge nitrided. The glow-discharge nitriding was performed with the following parameters: at 450 °C for 6 hours and at 530 °C for 4 hours. The results of the following tests are described and presented: metallographic (SEM), qualitative and quantitative analysis point EDS, measurement of hardness HV, hardness distribution, measurement of roughness parameters (Ra, Rz), wear resistance by the Amsler method. The results showed that the glow-discharge nitriding increases the hardness and the frictional wear resistance of thermal sprayed stainless steel X46Cr13 and X2CrNi18-9 coatings. The hybrid technology, combining thermal spraying of martensitic stainless steel X46Cr13 and glow-discharge nitriding at 530 °C for 4 hours, provides formation of a coating with the highest hardness and wear resistance of all the tested coatings. This coating can be applied to the regeneration of machine parts, which are required to have particularly high useful properties.

Published: January 2019

The Fasciola hepatica surface and whole body lectins (FHLs) were separated partially purified and tentatively identified. They are of protein nature and of glucose, lactose, and mannose-binding potentials. As well as they agglutinate sheep red corpuscles 2% suspension. FHLs are T lymphocyte mitogens, but the whole body lectins were more potent than surface lectins. Thus, whole-body lectin was selected for further study.T he whole body lectin stimulates specific antibody formation at both mucosal and systemic level, post to an oral immunization program in rabbits.T he immunodominant epitope can be of B cell or Th2 dependent nature and in combination with E. coli "O" antigen induces mucosal tolerance. E. coli induce significant leukocyte migration inhibitory factor ( LIF ) and the combination of E .coli -FHLs induced both significant macrophage migration inhibitory factor (MIF) and LIF in the immunoprimed rabbits.FHLs posses augmenting potential for the tuberculin skin DTH reaction indicating its cellular immunopotentiating ability. Bilateral humoral and cellular shared immunogenicity. Such shared character may be helpful in immunoprotection model of E.coli infection in one hand and source of confusion in immunodiagnosis of Fasciola infection, on the other hand. The conclusion of this study FHL functional epitope mapping, maps the following possible epitope, B or Th2 dependent.Th1, Tdth and or shared immunodominant epitopes.
