Problemas y tendencias de interpretación de las obras de arte en las actividades educativas de museos
Authors: Arriaga Azcarate Amaia
Published: February 2020

La teoría sobre la interpretación de las obras de arte ha influido en la forma en que los museos interpretan sus colecciones para los visitantes, esto es, en la manera en que exponen las obras, en el tipo de información que ofrecen los recursos interpretativos y en la forma en que los educadores interpretan las obras para o con los visitantes.Si bien encontramos bastante literatura relacionada con los estilos expositivos y los recursos interpretativos, poca investigación se ha realizado sobre el modo en que los educadores de museo enfocan la mediación entre las obras de arte y el público y las nociones de interpretación que subyacen en sus practicas educativas.En este artículo se analizan las concepciones de interpretación que subyacen en las actividades desarrolladas por educadores de museos. Se reflexiona sobre cómo las practicas de los educadores responden a las cuestiones fundamentales sobre la interpretación de las obras de arte. Por ejemplo, ¿el significado de una obra de arte reside en sí misma o es un constructo? ¿Cuáles son los límites y criterios para la interpretación? ¿Quién debería tener la autoridad en la interpretación?En la conclusión, se sugieren pautas para articular nuevas prácticas de educación museística que promuevan un modelo de interpretación consciente y crítico.

Authors: Quevedo Marcolino Taís , Medeiros Rodrigues Reali Aline Maria de
Published: February 2020

Los diarios reflexivos han sido utilizados como instrumento para facilitar el proceso de reflexión respecto de la acción, y así contribuir con el desarrollo profesional. Los feedbacks hechos a esos diarios, por mentores, son herramientas esenciales para la promoción del aprendizaje, pues contribuyen para la identificación de cuestiones que requieren más reflexiones. Para comprender mejor las posibilidades del trabajo del mentor con esta herramienta, fueron realizados análisis de contenido de los feedbacks de los diarios reflexivos de seis participantes de una investigación-acción, cuya intervención se caracterizó por ser un grupo de mentoría para terapeutas ocupacionales en el inicio de la carrera profesional. El análisis ha sido auxiliado por el software ALCESTE. Los resultados indican que el trabajo del mentor siguió cuatro cursos de acción: a) el trabajo acerca de la práctica explícita: la promoción de la reflexión respecto de los contextos y de los procedimientos; b) el trabajo más allá de la práctica: de los contenidos latentes al desarrollo profesional; c) el diario reflexivo y las conexiones con otras herramientas educacionales; d) las dificultades en la promoción de la reflexión. Cada línea de acción implicó tareas propias para la mentora. De este modo, las líneas de acción evidenciadas en esta investigación son coherentes con lo propuesto educacionalmente para el desarrollo profesional y pueden ser utilizadas como guías iniciales para apoyar el trabajo del mentor, y también para basar otras investigaciones respecto de procesos de mentoría y desarrollo profesional

Authors: Murillo F. Javier , Román Marcela
Published: February 2020

La brecha entre lo que se considera calidad de la educación y las acciones que se toman para evaluarla en América Latina es cada vez más amplia. Desde esa perspectiva, en este artículo se plantea la necesidad de asumir un enfoque global e integrador de la evaluación. Para ello se proponen principios y criterios que deben sostener esta evaluación y ser coherentes con los principios de aprendizaje a lo largo de la vida, una educación para todos y el desarrollo integral de los estudiantes como finalidad. También se sugieren cuatro temas que parecen prioritarios para avanzar en la mejora de la evaluación de la calidad de la educación: evaluar a los docentes, a los estudiantes en sus escuelas y al funcionamiento de las administraciones educativas; valorar la participación de la sociedad en la evaluación; abordar el estudio de factores asociados, y plantear la necesidad de la participación social en el diseño de las políticas de evaluación.
Canadian Regional Agriculture Model: Positive Mathematical Programming Applied to the Beef Sector in Canada
Authors: Colwill Timothy , Gill Ravinderpal
Published: February 2020

This paper describes the Positive Mathematical Programming (PMP), the method for calibrating models of agricultural livestock production and resource use using a nonlinear total cost function. The PMP method is applied to agricultural sectoral models to study changes in policy and market signals. The Canadian Regional Agriculture Model (CRAM) is a regional, multi-sectoral, comparative static, partial equilibrium, mathematical programming model developed and maintained by Agriculture and Agri-Food Canada (AAFC) since mid-eighties. The PMP process converts a linear model using flexibility constraints into a nonlinear model in the absence of the flexibility constraints. A component of CRAM is the beef sector. The elements of the set of total cost curves are defined as quadratic function in terms of the number of cows and calves in the beef production activities. The marginal cost curves are then approximated using the shadow values from linear programming solution with linear curves. Once the flexibility constraints were removed, the model automatically calibrates to the base year production levels. The results from four scenarios indicated the beef sector of CRAM could predict the impact of the scenarios on the size of beef herd. In Scenario 1 where cash costs were increased by 10 percent, the breeding herd size decreased from 3.73 percent in New Brunswick to 0.0 percent in Ontario and Quebec. In Scenario 2 where barley costs were decreased by 10 percent, the breeding herd size increased from 0 percent for British Columbia, Alberta, Ontario, Quebec, Prince Edward Island and Nova Scotia to 1.93 percent for New Brunswick. In Scenario 3 where carcass weight per beef cow could be increased by 10 percent, the increase in beef herd size ranged from 0 percent for Ontario and Quebec to 2.56 percent for New Brunswick. In Scenario 4 where world beef prices were increased by 10 percent increase in beef herd size ranged from 4.48 percent for Manitoba to 25.78 percent for New Brunswick.

Published: February 2020

The aim of the work was to study the epizootic situation on the occurrence of intestinal fluke diseases in foxes in Eastern Ukraine. The epizootic situation regarding fox fluke diseases was studied in vivo according to the results of feces coproscopy and posthumously by a partial helminthological autopsy according to K. I. Scrjabin. In total, 213 samples of feces from foxes were collected and examined by helminthologic methods. As a result of the research, the wide spread of intestinal fluke diseases was found in foxes of Eastern Ukraine. Two trematode species, Alaria alata and Nanophyetus salmincola, were found in foxes of the forest-steppe zone. In the Eastern Ukraine, the invasion of foxes with A. alata reaches 67.13%, mean intensity — from 2 to 38 eggs per microscopic field, median intensity — 12.7 ± 1.7. The invasion of foxes with N. salmincola is insignificant: prevalence — 0.93% with mean intensity — 1–8 eggs per microscopic field (median intensity — 4.5 ± 2.5). In the forest-steppe geographical zone of Eastern Ukraine, alariasis was found in 91.24% of foxes with low, medium, and high levels of mean intensity — from 3 to 47 eggs per microscopic field (median intensity — 16.5 ±1.0). Nanophyetiasis was detected in two foxes (prevalence — 1.45%) with median intensity — 4.5 ± 2.5 eggs per microscopic field.

The production of dried tea leaves and tea consumption in Indonesia has increased from year to year. This condition was directly proportional to the spent tea leaves produced. Spent tea leaves contained 37% cellulose which can adsorb heavy metals in polluted water. Iron (II) metal was often found in high concentrations in ground water, so a treatment process was needed. This study aimed to analyze the removal of iron (II) in water by using activated spent tea leaves.The type of this research was true experiment with a pretest-posttest controlled group design. Spent tea leaves with size 80 mesh was activated with 0.1 N HCl for 36 hours. The method was carried out with a batch system in an artificial iron solution the initial concentration was 9.85 mg / L, with mass of adsorbent was 10 grams, pH = 7, stirring speed 100 rpm, contact time 15 minutes, 25 minutes, and 35 minutes. Measurement of iron levels was carried out before and after treatment using the SSA method. FTIR test carried out before and after activated spent tea leaves were used adsorption. Data analysis was carried out descriptively and analytically (One-way Anova Test and LSD Test).The results showed that activated spent tea leaves can remove iron (II) levels in water. The result of One-way Anova test and LSD test, the higgest removal of iron (II) occurred at 35 minutes contact time with adsorption efficiency was 90.36%. FTIR test results showed that activated spent tea leaves in this study contained functional groups were O-H, C-H, C=O, C=C, and C-N.This study concluded that activated spent tea leaves can remove iron (II) in water. The higgest removal of iron (II) occurred at 35 minutes contact time. Further research is needed to achieve 100% adsorption efficiency and find an effort to reduce turbidity in sample water after treatment. Keywords: Clean Water, Iron (II), Spent tea leaves

Geography of brewery: development of spatial distribution of Czech beer market after 1989
Authors: Hasman Jiří , Hána David , Materna Kryštof
Published: February 2020

Much of the current research in economic geography focuses on spatial distribution of industries and their market competition. As the data about localization are relatively easily accessible, empirical studies are often conducted. However, our knowledge of retail distribution strategies is still incomplete. By examining 54 Czech breweries and their distribution regions, this article aims to fill the knowledge gap relating to retail distribution strategies in the brewing industry. Based on the Bennison typology of retail location strategies, which is used within the field of retail development, we identified four factors determining the decision on the future retail strategy of a specific brewery: geographic location, competitiveness, affiliation to a business group, and beer taste. As a result, the Czech beer market constitutes not only an attractive topic, but also an exceptional case for the study of economic actors’ spatial behaviour. The article tries to contribute to the social and scientific knowledge by adding a topic located on the borders of economic geography and retail geography which has not yet been studied in this way.

Modelling Colloidal Stability in Gold Nanoparticles Synthesis - A Review
Authors: Faith U. Babalola
Published: February 2020

Nanoparticles are commonly synthesized in colloidal systems, a liquid with suspended macromolecules. By the Brownian motion, these particles can collide and aggregate, leading to larger particles. To stabilize the aggregation process, charges induced by ions cause repulsion among the particles. Through the works of researchers in the past, various models for describing particles aggregation and stabilization have been developed and modified. These models are based on the popular DLVO theory, named after Derjaguin, Landau, Verwey and Overbreek. In this work, evidence illustrating aggregation and stabilization in gold nanoparticles synthesis is reported. Thereafter, models for describing aggregation by the Brownian motion and stabilization by the electrostatic effect are reviewed. The electrostatic effect among the particles is mathematically expressed as the cumulative sum of the Van der Waal’s energy of interaction and the electrostatic energy of repulsion. As the resulting stabilization model is too complex to solve, past researchers reported a simplified stabilization submodel and employed it in describing gold nanoparticles synthesis. Unfortunately, as shown in this review, the submodel failed to describe the synthesis as the aggregation process never stopped, thus making a case for a new modelling approach.
Contrapondo acordos entre pessoas e parques em contextos do Sul

Apresento, neste artigo, os resultados da pesquisa realizada no doutorado (2010-2016), acerca das estratégias engendradas por atores estatais, a fim de solucionar conflitos envolvendo projetos de desenvolvimento concorrentes: a criação de parques e a reparação histórica de comunidades negras por meio da titulação de seus territórios. Optei pelo estudo aprofundado de dois casos: o processo de titulação da comunidade quilombola de Ivaporunduva, localizada no Vale do Ribeira, e o da comunidade Bhangazi, situada na província de Kwazulu-Natal, África do Sul. Notei que, tanto no Brasil quanto na África do Sul, a conversão dos beneficiários em ‘nativos ecológicos’ (Ulloa, 2004) faz-se sob uma perspectiva de conservação pautada em um conceito de ambiente que mais se assemelha aos valores ocidentais, excluindo outras visões de mundo sobre o lugar demandado e suas agências.
