Dinámicas de poder en la minería extractiva argentina: el caso de Mina Veladero
Authors: Giménez Eisenacht Candela 
Published: December 2020

En el año 2015, las aguas sanjuaninas comenzaron a presentar altos niveles de cianuro. El origen de esta anomalía fue un derrame ocurrido en Mina Veladero, un emprendimiento minero que, a partir de entonces, fue puesto bajo la lupa. No son sólo los derrames de cianuro lo que se le critica, sino su localización dentro de una Reserva Natural y su violación a la Ley de Glaciares así como a algunas leyes provinciales. Mientras las organizaciones ambientalistas reclaman que los marcos legales nacional y provincial avalan su cierre, Mina Veladero sigue funcionando, e incluso expandiéndose. Lo que subyace a esta disputa es el aparente debate que opone a la economía y la sustentabilidad, que enmascara relaciones de poder entre los actores intervinientes a escala local y entre los países a escala internacional. Con base en esto, el presente artículo busca adentrarse en la estructura minera argentina, a partir del estudio de caso del proyecto minero mencionado, analizando cuáles son los pros y los contras de la actividad, para así entender por qué la mina sigue funcionando cuando existen leyes que justificarían su clausura.
Abstract
In 2015, the rivers of San Juan began to present high levels of cyanide. The origin of this anomaly was a spill that occurred in Veladero mine, a mining venture that, from then on, has been subject to criticism. It’s not only cyanide spills that are criticized, but its location within a Nature Reserve and its violation of the Glaciers Law as well as some provincial laws. Even though environmental organizations claim that the national and provincial legal frameworks guarantee its closure, Veladero mine continues to function and even to expand. What underlies this dispute is the apparent debate that opposes economy and sustainability, which masks power relations between the actors involved at a local level and the countries at an international level. Based on this, this article seeks to delve into the Argentine mining structure, based on the case study of the aforementioned mining project, analyzing the pros and cons of the activity, in order to understand why the mine continues to operate when there are laws that would justify its closure.

Published: December 2020

El presente trabajo se realizó con el objetivo de indagar el grado de cultura ambiental de un grupo de estudiantes pertenecientes al tercer año de una escuela secundaria y consistió en una encuesta escrita, individual y anónima realizada a 96 alumnos. La encuesta contó con cinco secciones tendientes a evaluar los conocimientos en temas ambientales generales, los hábitos cotidianos que podrían contribuir a un empeoramiento de la situación ambiental, su comportamiento cotidiano, sus intenciones de comportamiento respecto del cuidado ambiental y la importancia que le asignan a la educación en temas ambientales. Los resultados obtenidos permiten afirmar que el grupo de estudiantes analizados obtuvo un valor de aprobación en su cultura ambiental, de acuerdo con los parámetros de la educación secundaria del lugar en que residen, pero resultaron desaprobados en cuanto a sus hábitos cotidianos. De la investigación realizada surgió también que la mayoría de los estudiantes se mostró interesado en mejorar sus actitudes con el ambiente y en participar de charlas de capacitación que les permitan contribuir al cuidado ambiental.
Abstract
The present work was carried out with the objective of investigating the degree of environmental culture of a group of students belonging to the third year of a secondary school and consisted of a written, individual and anonymous survey carried out on 96 students. The survey had five sections aimed at evaluating knowledge on general environmental issues, daily habits that could contribute to a worsening of the environmental situation, their daily behavior, their behavioral intentions regarding environmental care and the importance they assign to education on environmental issues. The results obtained allow us to affirm that the group of students analyzed obtained an approval value in their environmental culture, according to the parameters of secondary education of the place where they reside, but they were disapproved in terms of their daily habits. From the research carried out, it also emerged that most of the students were interested in improving their attitudes towards the environment and in participating in training talks that allow them to contribute to environmental care.

Repercusiones defensivas del ataque sin portera en el balonmano femenino europeo de élite (Defensive repercussions of the attack without a goalkeeper in European elite womens handball)
Authors: Bonjour Camila , Tortajada Diego Andres , Dol Gonzalo , Gonzalez Andres 
Published: December 2020

El objetivo de esta investigación fue analizar la eficacia de las secuencias de ataque utilizando el cambio de portera - jugadora de campo y sus consecuencias en la siguiente fase defensiva en el balonmano femenino de élite. Se utilizó la metodología observacional. Se empleó un diseño observacional puntual, nomotético y multidimensional. La muestra estuvo compuesta por 571 secuencias de ataque de 50 partidos pertenecientes a la EHF Champions League 2018-2019 de balonmano femenino. Se elaboró un instrumento observacional ad hoc que presenta la combinación de formato de campo y sistemas de categorías. La calidad del dato fue probada mediante concordancia inter e intra observadores. Los resultados destacan que el principal motivo por el cual se hizo uso de la regla que posibilita el cambio portera-jugadora fue mantener la igualdad numérica luego de haber sufrido una sanción disciplinaria, y en menor medida para generar superioridad numérica 7x6. La eficacia presentó los valores más altos cuando se utilizó para generar superioridad numérica. Las situaciones de igualdad numérica 6x6 arrojaron peores valores tanto en eficacia lanzamiento como en pérdidas de pelota. Se concluye que los equipos al atacar con portería vacía asumen un riesgo importante de recibir un gol de forma rápida si el ataque no finaliza en gol, ya que las consecuencias defensivas inmediatas están directamente relacionadas con la eficacia en la fase de ataque.
Abstract. The objective of this research was to analyze the efficacy of the attack sequences performance using the goalkeeper-field player change and its consequences in the following defensive phase in the women´s handball elite. The observational methodology was used. The observational design was punctual, nomothetic and multidimensional. The sample was 571 attack sequences from 50 matches from EHF Women´s Handball Champion League 2018-2019. An ad hoc observational instrument was developed that presents the combination of field format and category systems. The quality of data was tested by inter and intra observer agreement. The results highlight that the main reason why the rule that makes the goalkeeper-field player change possible was used was to maintain numerical equality after having suffered a disciplinary sanction, and to a less extent to generate 7x6 numerical superiority. The effectiveness presented the highest values when used to generate numerical superiority. The 6x6 numerical equality situations throw worse values in both shooting efficacy and lost balls. It is concluded that the teams assume a significant risk of receiving a goal quickly if the attack does not end in goal, since the immediate defensive consequences are directly related to the effectiveness in the attack phase.
Las razones del cambio de desempeño laboral en los docentes de Educación Física en el contexto gallego (The reasons for changing jobs among Physical Education teachers in the Galician context)
Authors: Eirín Nemiña Raúl , Sanmiguel-Rodríguez Alberto , Rodríguez Rodríguez Jesús 
Published: December 2020

En este estudio analizamos las razones que justifican los cambios de desempeño laboral en los docentes de Educación Física (EF). De un modo concreto, nos preguntamos por las razones del desgaste profesional que sufren los docentes y que justifican los cambios y abandono de los docentes. Para ello desarrollamos un estudio descriptivo en el que participaron un total de 120 docentes de EF que realizan su función en las etapas de Educación Primaria y Secundaria en la Comunidad Autónoma de Galicia. Para la obtención de información cumplimentaron un cuestionario, elaborado a partir del Teacher Follow-up Survey. Destacamos que, en general, el profesorado indica que la escasa valoración hacia la EF por parte de la administración influye mucho en dicho cambio de trabajo. Igualmente, otro de los factores determinantes del cambio de desempeño laboral es la escasa consideración hacia la EF por parte de las familias. Los docentes cuando deciden buscar un nuevo horizonte profesional suelen optar por un cambio de especialidad y la dedicación a tareas de gestión docente.
Abstract. In this study we analyze the reasons that justify changes in job performance in Physical Education (PE) teachers. In a concrete way, we ask ourselves about the reasons for the professional burnout suffered by teachers and that justify the changes and abandonment of teachers. For this, we developed a descriptive study in which a total of 120 PE teachers participated, who perform their function in the stages of Primary and Secondary Education in the Autonomous Community of Galicia. To obtain information, they completed a questionnaire, prepared from the Teacher Follow-up Survey. We highlight that, in general, the teaching staff indicates that the low assessment of PE by the administration greatly influences this job change. Likewise, another of the determining factors of the change in job performance is the scant consideration for PE by families. When teachers decide to seek a new professional horizon, they usually opt for a change of specialty and dedication to teaching management tasks.

Revisión sistemática del entrenamiento de fuerza en futbolistas pre-adolescentes y adolescentes (Systematic review of strength training in preadolescent and adolescent football players)
Authors: Martínez-Pérez Pablo , Vaquero-Cristóbal Raquel 
Published: December 2020

El objetivo del presente estudio fue realizar una revisión sistemática sobre los efectos de los programas de fuerza utilizados en futbolistas varones pre-adolescentes y adolescentes. Se analizaron un total de veinticinco artículos, en español o en inglés, a raíz de la búsqueda en PubMed, ISI Web of Knowledge y SportDiscus. Se encontró que el entrenamiento pliométrico, seguido del entrenamiento de fuerza-resistencia y el entrenamiento isoinercial, por ese orden, son los comúnmente empleados para el entrenamiento de fuerza en futbolistas pre-adolescentes y adolescentes. Sin embargo, en función del estado madurativo, y del bagaje motriz del jugador, parecen generar diferentes adaptaciones en estos, y por tanto, requieren de una individualización de la carga de entrenamiento en función de su nivel tanto físico, como técnico.
Abstract. The aim of the study was to do a systematic review about the effects of strength programs used in pre-adolescent and adolescent male football players. A total of twenty-five articles, in Spanish or English, were analyzed by searching PubMed, ISI Web of Knowledge and SportDiscus. Plyometric training, followed by strength-resistance training and isoinertial training, in that order, were found to be commonly used for strength training in pre-adolescent and adolescent footballers. However, depending on the maturation state, and the player's motor experience, they seem to generate different adaptations in these, and therefore, require an individualization of the training load depending on their physical and technical level.

Estimación de la fenología de la vegetación a partir de imágenes de satélite: el caso de la península ibérica e islas Baleares (2001-2017)
Authors: Caparros-Santiago J.A. , Rodríguez-Galiano V.F. 
Published: December 2020

Phenological dynamics of vegetation is considered as an important biological indicator for understanding the functioning of terrestrial ecosystems. Land surface phenology (LSP), the study of vegetation phenology from time series of vegetation indices (IV), has provided a comprehensive overview of ecosystem dynamics. Iberian Peninsula is one of the regions with the greatest diversity of ecosystems in European continent. It is therefore an excellent study area for monitoring phenological dynamics of vegetation. The aim of this study is to analyse the spatial variability of the phenology of the vegetation of the Iberian Peninsula and Balearic Islands for the period 2001-2017. NDVI (Normalized Difference Vegetation Index) time series were generated from the surface reflectance product MOD09Q1 at a spatial resolution of 250 meters and with a composite period of 8 days. Atmospheric disturbances and noise were reduced using a Savitzky-Golay smoothing filter. Different phenological metrics or phenometrics were extracted using a threshold-based method. Results showed the existence of a different behaviour between spring and autumn phenophases in the Atlantic and Mediterranean biogeographic regions. The Mediterranean mountainous areas showed a similar phenological behaviour to the Atlantic vegetation. Biogeographic regions showed an internal variability, which may be derived from the different behaviour of land covers (e.g., natural vegetation vs. crops).
Staining Cells with Extracts Prepared from Flowers of Bougainvillea X Buttiana.
Authors:   , Towet Paul 
Published: December 2020

Background: Staining is the application of dyes to specimens to impart colour to cells through a chemical reaction. The study aimed at finding plant extracts to stain human blood cells, stem sections of Amaranthus species, Gram-negative organisms such as Escherichia coli, and Gram-positive organisms such as Staphylococcus aureus. Methodology: Healthy mature flowers of Bougainvillea X buttiana and Amaranthus species plants were picked from gardens around the University of Kisubi. Bracts of Bougainvillea X buttiana were separated from other flower parts and air-dried. Both negative and positive controls for cells were prepared. Results: White blood cells, platelets, and cells of Escherichia Coli and Staphylococcus aureus did not stain under all treatments with the extracts while human red blood cells and stem sections of Amaranthus species stained under certain treatments with the extracts. The extracts were more successful in staining stem sections of Amaranthus species as compared to human red blood cells where staining occurred in very few circumstances. Stem sections of Amaranthus species required shorter to stain effectively while human red blood cells required longer to stain effectively. Conclusion: Extracts of the bracts of Bougainvillea X can be experimented with various cells when their pH is neutral and alkaline.

Abstract

Background:
Sexual dysfunction in multiple sclerosis (MS) is a significant but overlooked impairment, and treatment options are rare. The aims of this systematic review were to identify psychological interventions used to treat sexual dysfunction in MS, to estimate their benefit, and to note appropriate treatment approaches for research projects and clinical use.

Methods:
A systematic review update was conducted to find psychological interventions aiming to improve sexual dysfunction in MS. A comprehensive search and review of MEDLINE, PsycINFO, CINAHL, and PubMed were completed, and the effects and quality of selected studies were reported.

Results:
Six publications with 295 participants were identified. All selected studies assessed the effectiveness of psychological interventions on sexual dysfunction or sexual satisfaction in people with MS; four studies directly targeted sexual dysfunction in MS, one was a mindfulness yoga program to improve fatigue and quality of life, and one other presented a secondary analysis of a study targeting depression in MS. All six studies reported significant improvements in sexual dysfunction or sexual satisfaction and somewhat in psychological variables.

Conclusions:
A pressing need for development and adequate evaluation of psychological interventions for sexual dysfunction in MS remains. In addition, assessment of sexual dysfunction in MS and its treatment should be more focused in clinical care.
