Published: February 2020

Inadequate insulin secretion in response to glucose is an important factor for β-cell failure in type 2 diabetes (T2D). Although HMG-CoA reductase degradation 1 (HRD1), a subunit of the endoplasmic reticulum–associated degradation complex, plays a pivotal role in β-cell function, HRD1 elevation in a diabetic setting contributes to β-cell dysfunction. We report in this study the excessive HRD1 expression in islets from humans with T2D and T2D mice. Functional studies reveal that β-cell–specific HRD1 overexpression triggers impaired insulin secretion that will ultimately lead to severe hyperglycemia; by contrast, HRD1 knockdown improves glucose control and response in diabetic models. Proteomic analysis results reveal a large HRD1 interactome, which includes v-maf musculoaponeurotic fibrosarcoma oncogene homolog A (MafA), a master regulator of genes implicated in the maintenance of β-cell function. Furthermore, mechanistic assay results indicate that HRD1 is a novel E3 ubiquitin ligase that targets MafA for ubiquitination and degradation in diabetic β-cells, resulting in cytoplasmic accumulation of MafA and in the reduction of its biological function in the nucleus. Our results not only reveal the pathological importance of excessive HRD1 in β-cell dysfunction but also establish the therapeutic importance of targeting HRD1 in order to prevent MafA loss and suppress the development of T2D.

Published: February 2020

En Costa Rica se han incrementado los nuevos diagnósticos del virus de inmunodeficiencia humana (VIH). La epidemia afecta desproporcionadamente a hombres que tienen relaciones sexuales con hombres (HSH). Por consiguiente, el foco de interés de este estudio se centró en la conducta de protección de estos y la identificación de predictores del uso del condón. El estudio persiguió indagar: a) estrategias personales de protección ante una infección por VIH de HSH de 18 a 24 años en Costa Rica, b) consistencia del uso del condón de este grupo con parejas ocasionales, c) en qué medida puede validarse el modelo de información, motivación y habilidades conductuales (IMB, por sus siglas en inglés) como explicativo del uso del condón. Se realizó una muestra de accesibilidad de 238 HSH de 18 a 24 años. La recopilación de datos se efectuó a través de entrevistas personales estandarizadas. El análisis estadístico se efectuó mediante estadística descriptiva y procedimientos bi y multivariadas. La comprobación del modelo IMB se realizó mediante modelos de ecuaciones estructurales. Los 119 encuestados con parejas ocasionales en los seis meses previos señalaron una amplia gama de estrategias personales de protección. Solo 5.6 % indicó no tomar conscientemente precauciones frente a una infección. De los participantes que mantuvieron relaciones anales con parejas ocasionales en los seis meses previos, 13.4 % indicaron haber utilizado siempre un condón. La prueba del modelo IMB evidenció que el uso del condón está codeterminado por la estrategia personal y la severidad percibida de una infección. Es decir, el modelo IMB no se comprobó en su totalidad. El estudio genera información que puede servir como base para la prevención y destaca el rol de las estrategias personales de protección frente al VIH y de inhibidores situacionales y relacionados a la pareja. Los resultados invitan a la extensión del modelo IMB.

Published: February 2020

La contratación de proveedores de tercera parte logística (3PL) ha venido aumentando en los últimos años a nivel mundial y local. Uno de los servicios que más se terceriza es el transporte. La contratación de un proveedor de tercera parte para el transporte terrestre de mercancías es un problema de decisión multicriterio que debe ser abordado con herramientas adecuadas de manera que se garantice la mejor contratación posible considerando los criterios que la organización contratante considere para esta transacción. El presente trabajo propone un desarrollo multicriterio a partir de la utilización del proceso analítico jerárquico difuso (AHP difuso) y TOPSIS para la selección de un proveedor de tercera parte en el transporte terrestre de mercancía incluyendo el riesgo operacional como uno de los criterios de selección. La propuesta es aplicada para la selección de un transportador por parte de una empresa manufacturera del Valle del Cauca en Colombia.
Pedagogia e diversidade cultural
Authors: Azevedo Samara Moço , André Bianka Pires
Published: February 2020

O desrespeito ao outro e às diferenças tem provocado significativas discussões no âmbito acadêmico e no cenário educacional. Estas têm alcançado não só a escola básica, mas também as instituições que oferecem cursos de licenciatura, onde tem-se refletido e buscado uma formação que contemple o multiculturalismo como política educacional, a fim de valorizar e promover a diversidade cultural como realidade latente e concreta na sociedade brasileira. Assim, torna-se relevante refletir e repensar como a diversidade cultural tem sido tratada em cursos de Licenciatura em Pedagogia, tendo em vista as demandas da sociedade, do contexto escolar e acadêmico na contemporaneidade.
Internacionalização do ensino superior
Authors: Macedo Maria do Socorro Alencar Nunes
Published: February 2020

Neste artigo examinamos dados de uma universidade pública tomando como referência o discurso sobre internacionalização presente em seus documentos oficiais e na fala da assessoria internacional.   A partir de uma perspectiva descolonial aliada a uma compreensão da língua como um discurso socialmente situado, buscamos identificar elementos que indiquem a perspectiva de internacionalização da política institucional, evidenciando possíveis marcas da lógica colonial. A análise dos documentos oficiais e da entrevista com a assessora indica  uma adesão à tendência dominante que têm o inglês e os países do Norte como principal destino para a construção de parcerias internacionais, em detrimento de uma postura mais crítica que considere, em igual medida, os países da América Latina e outros do Sul-Global como possibilidades reais de investimento em parcerias mais efetivas e menos assimétricas.

Published: February 2020

There is a research shortage on environmental education management indicators, which have allowed a specific sustainability criterion for schools. This study aimed to evaluate the effectiveness and use of Environmental Sustainability Indicators (ESI) in the Brazilian Federal Institutes of Education (BFIE) to verify the efficiency of environmental management education. The equation used in the survey indicates that rates close to zero suggest maximum inefficiency in conservational management, whereas an index of 1, suggests maximum efficiency in environmental management. The equation has the variables pi = score assigned to the variable i; n = total number of variables i, i = 1, ..., 09 and m = total number of campuses j, j = 1, ..., 230. The Index of Environmental Performance in Federal Institutes (IEPFI) obtained in this study showed that the campuses presented indexes that did not exceed the value 0.35, where the ideal value would be 1.0.
Educação superior e solicitações da realidade
Authors: Lima Paulo Gomes
Published: February 2020

Embora com desenhos distintos de Educação Superior, Brasil e Portugal não escapam à  lógica do conflito, visto que as solicitações sociais, quando atendidas, são circunscritas às políticas de varejo – isto é, tem um alcance limitado de atendimento aos cidadãos quanto à oportunização, condições de acesso, permanência do/a estudante  e o sucesso delimitado pela lógica de mercado em nível de promessa. Se de fato, os jovens das nações correspondem ao projeto de futuro que se deseja,  as políticas e formação correlata de profissionais devem garantir uma performatividade correspondente.  Diz-se, entretanto, que o custo para tal empenho possa ser inalcançável por inferir em tempo, materiais específicos, intercâmbios, dentre outros; por outra lado, sabe-se, mais caro e inoperante será a educação superior de um país que não oportuniza a formação necessária aos seus jovens, independente de classe social – desde que iminentemente eivado de vontade e disposição para trilhar tal desenho.
Um giro decolonial
Authors: Tavares Manuel , Santos Eduardo
Published: February 2020

A proposta que discutimos neste texto, de uma epistemologia crítica pós-colonial em oposição à epistemologia ocidentocêntrica, segue a produção teórica dos autores do Grupo Modernidade-Colonialidade (MC). O diálogo intercultural e o intercâmbio de experiências e significações vazadas em outras racionalidades que, com alguma legitimidade, poderão ter a pretensão de alguma universalidade, são propostos no texto como a outra face possível de sociedades de conhecimento emancipatório, em oposição ao simplismo de sociedades de mercado. Dessa forma, buscamos ampliar os horizontes teórico-epistêmicos que potencializem a construção de uma nova geopolítica do conhecimento, a partir da diversidade de saberes e culturas que existem no Sul. A tese central do texto é que a defesa dos processos de decolonialidade das instituições educativas constitui pressuposto da construção de uma outra geopolítica do conhecimento. Nossas teorizações se concentram no território latino-americano e se valem de exemplos da educação brasileira.

The paper analyzes the strategies for the profes-sional adaptation of young scientific and teaching personnel. Based on the results of a sociological survey of graduate students of the Russian Tech-nical University MIREA, the authors identify the main directions of the university personnel policy in work-ing with youth. They pay particular attention to the study of the components that determine profes-sional self-identification of graduate students. The paper assesses the dependence of academic mobili-ty of postgraduate students and their scientific ac-tivity on various factors. The study of the evolving practice of training scientific and scientific-pedagogical personnel allows to focus on creating academic environment conducive to scientific activi-ty of graduate students and improvement of the quality of ongoing research projects. Today, active participation of graduate students and teachers of a department in scientific work of the university be-comes one of the indicators of successful scientific activity of its structural divisions. The identified low estimate of the demand for research activity in a number of structural divisions is largely determined by the low level of fulfillment of the basic needs of graduate students in connection to further career development in academia. In this regard, the direc-tion of the formation of resources of educational institutions is significant both on the basis of moti-vation for research activities, and on expanding youth access to scientific design.
Methodical Aspects of Developing Stability of 13–15-Year Old Young Rifle and Pistol Shooting Athletes in the System “Shooter – Gun – Target” Taking Into Account the Temperament
Authors:   Moscow Pedagogical State University, Shilenok Veronika Viktorovna
Published: February 2020

The study considers the influence of temperament peculiarities on the dynamics of the number of mis-takes made by young rifle and pistol shooting ath-letes aged 13–15 years in excess of permissible ped-agogical requirements taking into account sports categories in PP-2 exercise (40 shots with an air pis-tol at a distance of 10 meters) through the example of a sample group of 90 pistol athletes. The identi-fied problem areas of maintaining stability in the “shooter – gun – target” system led to the develop-ment of the content of pedagogical requirements for threshold values of permissible mistakes made by young rifle and pistol shooting athletes when exe-cuting a series of 10 shots taking into account their sports qualifications. The study provides specifics of competitive activity performance, the stability shown in the “shooter –gun – target” system, as well as the requirements which should be met by rifle and pistol shooting athletes to be qualified for a certain sports rank taking into account their type of temperament: 54.4% of the sample group are phlegmatic people with the highest sports ranks, 31.7 % are sanguine people and 13.9 % are choleric ones. The largest number of mistakes, according to young rifle and pistol shooting athletes (n = 90) and coaches (n = 10), was caused by the following: hast-iness, spontaneity of the onset of action, sudden movement when pulling the trigger, inattentiveness to the technique of executing a shot. To a greater extent, such mistakes are made by choleric athletes, i.e. 9.39 mistakes out of 40 shots, to a lesser extent – by athletes of sanguine (4.99) and phlegmatic (4.96) types respectively. The data obtained make it possi-ble to identify specific aspects of influence of vari-ous types of temperament on stability in the “shooter – gun – target” system, as well as on the occurrence of mistakes when performing a competi-tive exercise and thus allow to improve and adjust a sports training program. The study describes the key problems during psychological adaptation of young shooting athletes to the execution of a series of 10, 20, 40 and 60 shots, and the content of seman-tic units of psychological attitudes and mental im-ages that improve behavior during trainings as well as in a competitive environment.

Published: February 2020

The present study considers the relationship be-tween the processes of regional identity and public communication. The relevance of the theme is de-termined by the need to overcome possible negative trends in the development of interethnic and inter-faith relations in the border territories of the Russian Federation. The expansion of contact zones be-tween ethnic groups in the conditions of developed federalism is a typical process of the current social situation in the country. It seems possible to devel-op not only state, but also regional identity within the framework of Russian national policy. The au-thors consider regional identity as a personal and group set of cognitive symbols that form an inte-grated representation of the surrounding locus. Identity is discussed at the micro-, meso- and mac-ro-social levels from the viewpoint of the sociologi-cal approach. The research presents the classifica-tion of the studied phenomenon reproduction sce-narios, the factors that influence the choice of a particular scenario. Special attention is devoted to the consideration of actors and stakeholders of identification processes at the territorial level, the specific character of administrative and public im-pact in the space of public communication.

Authors:   Magnitogorsk State Technical University, Musiychuk Maria Vladimirovna , Yatsenko Tatyana Vladimirovna ,   Baranovichi State University
Published: February 2020

The analysis of modern psychological studies of victimhood has allowed to identify the following predictors of adolescents falling into the risk group of increased vulnerability to victimizing influences and predisposition to consolidation of victim behav-ior patterns: immaturity of the system of value orien-tations and self-worth factors, seeking external evaluation in determining the significance of their own personality, diffuse representations of their "self", the intensity of self-consciousness formation and, as a consequence, exposure to social influ-ence. Statistical data analysis was carried out by regression analysis of data based on the methods of studying victimization and propensity to deviant behavior. Multiple linear regression was calculated using a direct stepwise method. Predictors of vari-ous types of addictions belonging to the types of victim deformation of personality of adolescents were revealed. The conducted research proved that victim deformation of personality of adolescents, degree of formation of patterns of vic-tim behavior and existence of experience of repro-duction of the model of victim behavior in various vital spheres essentially increase the risk of various types of addictive behavior in adolescents as a pas-sive, maladaptive way of coping with difficult life situations corresponding to defensiveness, insecuri-ty, social passivity and learned helplessness that are common in victim adolescents.
SILICON NUTRITION IN ALLEVIATING SALT STRESS IN APPLE PLANT
Authors: Aras Servet
Published: February 2020

Salinity is one of the major environmental stresses that adversely affect fruit yield and quality. Thus, finding an effective way of ameliorating salinity damage is important for sustainable fruit production. Silicon (Si) treatment effectively counteracts the effects of many abiotic stress factors such as salinity, drought, cold, iron deficiency. To probe into the potential alleviating salinity malignant effects, we investigated the protective roles of Si. An apple plant (Malus domestica Borkh.) cv. ‘Fuji’ grafted on M9 clonal rootstock was chosen for the experiment and imposed to salinity stress for 4 months with 35 mM NaCl. Si with different three doses (0.5, 1 ve 2 mM) was applied to the roots of the salt-stressed apple plants except control. Si treatments inhibited apple plants growth depression through increasing stomatal conductivity, chlorophyll and decreasing electrolyte leakage. 0.5 mM Si improved root:shoot dry weight under salinity condition. The lowest values of membrane permeability were found in 0.5 and 2 mM Si treatments (21.45 and 21.55%, respectively) while salt had the highest value (48.43%). Salt exhibited a rapid decrease in stomatal conductivity by 49% compared to the control. We hypothesis that Si treatment contributed to cell walls, involving membrane stabilizing and fortification. Our findings showed that Si increased apple plant tolerance against salinity.

Authors: Karaat Fırat Ege
Published: February 2020

Rain-fed agriculture is a common growing system relies on rainfall for water requirements of crops. This factbrings some drawbacks in cultivation that causes significant differences in yield and quality. However, fruitsfrom rain-fed trees are generally accepted as better tasting thanks to their richer flavor and aroma compounds. This study compares pomological parameters, some selected chemical properties, fatty acid composition and volatile aroma compounds of irrigated and rain-fed grown ‘Ferragnes’ and ‘Ferraduel’ almond cultivars. Results indicated significant differences between cultivars and growing systems. Total oil was significantly lower in rain-fed samples (24.8% for ‘Ferragnes’ and 24.9% for ‘Ferraduel’) when compared with irrigated samples (44.1% for ‘Ferragnes’ and 40.2% for ‘Ferraduel’). Palmitic and oleic acid was higher in irrigated samples, whereas linoleic acid was higher in rain-fed samples. Most of the aroma compounds detected in this present study are new record for almond aroma-active compounds. In an overall view, rain-fed samples resulted with higher contents of aroma compounds.

Authors: Pekşen Aysun , Kibar Beyhan
Published: February 2020

Macrolepiota procera, commonly called the Parasol Mushroom, is a delicious mushroom collected from the nature and commonly consumed by the public in many regions of Turkey. This study was conducted to determine the optimum culture conditions (pH, temperature, carbon and nitrogen sources) for mycelial growth of M. procera. Three pH values (pH 5.0, 5.5 and 6.0), four incubation temperatures (15, 20, 25 and 30°C), seven carbon (C) sources (dextrose, glucose, lactose, maltose, mannitol, sucrose and xylose) and six nitrogen (N) sources ((NH4)2HPO4, NH4NO3 and Ca(NO3)2, malt extract, peptone and yeast extract) were investigated. In the second step of the study, the effect of seven pH values (4.0, 4.5, 5.0, 5.5, 6.0, 6.5 and 7.0) on the mycelial colony diameter was examined at 20 and 25°C since these temperatures gave the best mycelial growth in the previously conducted temperature experiment. The best mycelial growth was determined at pH 6.0. The optimum temperature for mycelial growth of M. procera was found as 25°C. The use of glucose as carbon source and yeast extract and peptone as nitrogen source in the culture medium gave the best results for mycelial growth. Determining of optimum culture conditions for mycelial growth of M. procera will provide important contributions to the fortcoming studies on it’s commercially cultivation in Turkey.
ASSESSMENT OF PHYSIOLOGICAL AND MORPHOLOGICAL TRAITS OF PLANTS OF THE GENUS Fragaria UNDER CONDITIONS OF WATER DEFICIT – A STUDY REVIEW
Authors: Rokosa Marta , Mikiciuk Małgorzata
Published: February 2020

The genus Fragaria belongs to the Rosaceae family. The most popular representatives of this species are the strawberry (Fragaria × ananassa Duch.) and wild strawberry (Fragaria vesca L.), whose taste and health benefits are appreciated by a huge number of consumers. The cultivation of Fragaria plants is widespread around the world, with particular emphasis on the temperate climate zone. Increasingly occurring weather anomalies, including drought phenomena, cause immense losses in crop cultivation. The Fragaria plant species are very sensitive to drought, due to the shallow root system, large leaf area and the high water content of the fruit. There have been many studies on the influence of water deficit on the morphological, biochemical and physiological features of strawberries and wild strawberries. There is a lack of research summarizing the current state of knowledge regarding of specific species response to water stress. The aim of this study was to combine and compare data from many research carried out and indicate the direction of future research aimed at improving the resistance of Fragaria plants species to stress related to drought. These plants show patterns of response to stress caused by drought, such as: osmotic adjustment, reduction of transpiration and photosynthesis, and increased efficiency of water use. Drought also causes significant changes in the composition and palatability of the fruit of the Fragaria plant species.

The study was conducted in 2017 in the district of Sivas. In the study, 20 genotypes, which are considered to be different from each other, taking into account the fruit characteristics such as color and size and shape, were determined from the hawthorns that were naturally grown in the flora of Suşheri. At harvest time, the fruit, which would be adequate for pomological and biochemical measurements and analyzes, was harvested. According to the results of the measurements and analyzes in the study, fruit weight was found to vary between 0.68 g and 6.35 g, fruit width was between 10.52 and 29.48 mm and fruit length was between 11.40 and 20.67 mm. The highest firmness values were recorded with the genotype (G) 20 genotype, while the G4 had the lowest values in terms of the firmness values of the fruit flesh. While there are no significant differences between the pH values of the genotypes, the differences between the genotypes in terms of SSC, TA and vitamin C contents are quite significant. It has been found that there are significant differences between the genotypes in terms of total phenolic, total flavonoid and antioxidant activity. The total phenolic content ranged from 218.8 (G17) to 605.8 (G5 and G8) mg GAE kg–1 f.w., while the lowest total flavonoid content was 21.58 (G 17) and the highest total flavonoid content was 67.75 (G9) mg GAE kg–1 f.w. When the antioxidant activity was evaluated, the DPPH values were 1.08 (G17) – 15.43 (14) mmol TE kg–1 f.w., the FRAP values were 15.43 (G16) – 47.23 (G8) mmol TE kg–1 f.w. respectively.

Authors: Hicks Terrence , Heastie Samuel , Allen Tawannah , Ford Shelton , Taylor Robert
Published: February 2020

The primary purpose of this study was to determine the differences in the levels of social engagement between first-generation and other college students enrolled in a STEM discipline at a Historically Black College and University. A two-group ex post facto research design using a single questionnaire was used for the study. A stratified sample of 90 college students participated in the study. The data for the research questions were analyzed using descriptive and inferential statistics based upon the subscales of the College Student Experiences Questionnaire. These findings indicated that there were significant differences among first-generation and other college students who were enrolled in a STEM discipline at an HBCU. Statistically significant differences between first-generation and other college students were found for three items in the social integration category: “met other students,” (p = .017, η2 = .063); “used campus recreational facilities,” (p = .050, η2 = .043); and “became acquainted with students,” (p = .035, η2 = .050). Both groups felt that meeting others would happen “often.” Both groups differ for using campus recreational facilities and becoming acquainted with students whose family backgrounds were different. Firstgeneration students reported that “occasionally” and “often”; and the other college students felt “often” and “very often” that using campus recreational facilities and becoming acquainted with students whose family background was different would happen. The study documented the impact of the nurturing environment that exists at an HBCU and focused on the social engagement aspects of attending college. The study findings provide clues to ways that college administrators and researchers can assist first-generation college students enrolled in a STEM discipline at an HBCU. Implications for future research and policymakers are discussed.
The Impact of a Camp Orientation Program on First-Year Academic Engagement and Persistence
Authors: Haynes Michael R. , Atchley T. Wayne
Published: February 2020

More and more, institutions of higher education are being held accountable for student success measures such as persistence and completion rates. If research indicates that higher levels of student engagement lead to better academic outcomes, it is then reasonable to equate this to improved retention and graduation rates. The present study presents findings associated with a camp orientation program for first-year students and its impact on levels of academic engagement and persistence. Data collected from the Beginning College Survey of Student Engagement (BCSSE) and National Survey of Student Engagement (NSSE) were used to determine if statistically significant differences exist between camp participants and non-participants. Findings indicate no statistically significant difference between camp participants and non-participants on NSSE benchmarks related to academic satisfaction, enriching educational experiences, student-faculty engagement or persistence from fall to spring of the first college year.
Transition Programs for Student Veterans
Authors: Ritz Gary , Heggen Alyssa , Ericson Katie , Harris Jacqueline
Published: February 2020

Many times, student veterans are returning to, or entering for the first time, an institution of higher education at an older age than the traditional student, and with very different background experiences. As institutions prepare a welcoming environment for their matriculating students, an orientation program for student veterans, supplemental to the already existing orientation, is suggested. Doing so provides all the necessary information to the student veteran about the institution, along with a separate time to create a support group with their peers. The program described was implemented at a four-year, public, Midwestern university in the fall semester of 2011. Through a multi-pronged approach, student veterans were offered a variety of resources to help ease their transition from “boots to books.” An analysis of the data on the students who participated in the activities was compared to data on the students who were not involved. The results of the analysis show positive support for continuing the specialized orientation program.
El uso de las fuentes en los manuales de Historia en el bachillerato en España
Authors: Sánchez Ibáñez Raquel , Álvarez Martínez-Iglesias José María
Published: February 2020

Este artículo muestra los resultados de una investigación cuyo objetivo fue evaluar el empleo de fuentes en los manuales de Historia de 1. º de bachillerato. Para ello se han analizado cinco editoriales que se encuentran entre las más vendidas en España. Se han seleccionado los temas relacionados con la Guerra Fría, por tratarse de un conflicto internacional que puede estudiarse a través de fuentes de diversa naturaleza. Los resultados son similares a otros países europeos, como Francia, y evidencian que las fuentes se usan de forma equilibrada para ilustrar contenidos y para un fin didáctico. Sin embargo, en las actividades que incorporan fuentes, las demandas cognitivas solicitadas al alumnado son muy básicas por lo que se dificulta que este adquiera unas competencias históricas.

La Ley de Acciones Afirmativas para Afrodescendientes promulgada en Uruguay el 21/8/2013 establece que los programas educativos y de formación docente deben incorporar los aportes de las comunidades afrodescendientes a la enseñanza de la historia y su participación en la construcción de la nación, así como sus diversas expresiones culturales. Pretendemos analizar los ecos y las irrupciones de este campo haciendo dialogar los aportes del análisis político del discurso, con el campo político afrodescendiente en América Latina y el Caribe y sus demandas desde la perspectiva poscolonial/decolonial para mostrar cómo aparecen algunas referencias a la historia de África y a los aportes de la cultura afrodescendiente en los marcos normativos y en los programas oficiales de Historia para educación media en Uruguay.
Aprender historia del arte mediante salidas didácticas. Una experiencia en educación superior
Authors: Moreno-Vera Juan Ramón , Monteagudo Fernández José
Published: February 2020

En la experiencia que aquí se presenta, estudiantes de la Universidad de Murcia dejaron las aulas por unas horas para llevar a cabo un aprendizaje situado de la historia del arte mediante un itinerario didáctico sobre la Murcia medieval. De este modo, se rompen las barreras físicas del aula y se integran los elementos de aprendizaje con el propio paisaje urbano por donde los estudiantes pasan a diario. El itinerario didáctico partía desde el antiguo Alcázar Seguir de la ciudad, hoy Convento de clausura, pasando por la plaza de Santo Domingo, antigua plaza del zoco; la conjunción urbana de “las cuatro esquinas”, donde convergen las calles de los principales gremios de la ciudad; la catedral de Murcia, donde se conservan los restos de la antigua mezquita Al-Jama y, finalmente, en el conjunto monumental de San Juan de Dios, donde aún es visible el nicho del mihrab del antiguo oratorio del Alcázar mayor medieval. Los resultados de la investigación se basan en el análisis de un pre-test y un post-test que el alumnado contestó sobre sus conocimientos de la Murcia medieval. La progresión de aprendizaje del alumnado participante fue positiva mejorando en el post-test los resultados previos.
Escuela, historiografía y nación. El caso de la representación de Francisco Pizarro y la conquista española
Authors: Romero Meza Eddy Walter
Published: February 2020

La conquista o invasión española continúa siendo uno de los temas más sensibles en la enseñanza de la historia peruana. Un personaje central es el conquistador Francisco Pizarro, ubicado entre un discurso histórico prohispanista y un enérgico discurso antihispanista en la historiografía nacional. Las representaciones históricas en los textos escolares han partido en gran medida de las interpretaciones que la historiografía peruana ha propuesto. La escuela ha reproducido así las imágenes que sobre Francisco Pizarro y la conquista ha desarrollado nuestra tradición historiográfica. Sin embargo, esta historiografía ha oscilado entre una mirada conservadora o hispanofílica y una mirada crítica o hispanofóbica. Las representaciones de Pizarro y la conquista permiten distinguir, además, diferentes concepciones de la nación entre los historiadores y autores de textos escolares. Para unos, Pizarro constituye un personaje fundador (de la capital y el Perú), así como el iniciador del “mestizaje”; para otros, es el destructor de la gran civilización inca y autor del genocidio de la “verdadera nación”, la indígena. Los textos de divulgación escolar y sus autores permiten aproximarnos a los conflictos entre la historia oficial criolla y las versiones críticas nacional-indigenistas; y, finalmente, a los cambios y las nuevas narrativas históricas surgidas en las últimas décadas.

Identidad, memoria y enseñanza de la historia
Authors: Bracho Martínez Jorge Ángel
Published: February 2020

La importancia de la enseñanza de la historia se puede medir por los propósitos en ella implícitos. También, porque lo que con ella se estampa en la memoria es válido para toda la vida. Se sabe que muchas de las imágenes con las que los actores sociales asumen su existencia vital se asocian con lo aprehendido en la infancia y la juventud. La ductilidad de la mente humana, a temprana edad, es propicia para fijar en ella representaciones y configuraciones con las cuales se afinan formas de pertenencia territorial, política y cultural; he allí uno de los elementos clave para abordar algunos aspectos de la enseñanza de la historia en tiempos de parcialidad cultural y moldeados bajo la idea de revolución. Las líneas que siguen se enmarcan en una breve aproximación a libros de texto de la colección bicentenaria, dedicados a la enseñanza de la historia y divulgados en Venezuela a partir del año 2012, así como también a algunos valores culturales afines con el proyecto político desplegado desde 1998, entre los que se destaca la afrodescendencia y sus concomitancias.
Tomás Cornejo C., Ciudad de voces impresas. Historia cultural de Santiago de Chile, 1880-1910. México-Santiago: Colmex-Centro de Investigaciones Diego Barros Arana, 2019. 424 p.
Authors: Bello Kenya
Published: February 2020

El año es 1896 y el escenario la capital chilena. Los actores, tanto las élites como las clases trabajadoras, cuyas reacciones a un hecho de sangre, el asesinato de Sara Bell, están sedimentadas en distintos formatos impresos: periódicos, hojas sueltas, novelas de actualidad, prensa satírica e incluso piezas dramáticas llevadas a las tablas. Con esa pluralidad de fuentes, en este volumen compuesto por siete capítulos, Tomás Cornejo reconstruye con pericia y profundidad los diferentes circuitos desde los cuales se produjeron y difundieron discursos culturales alrededor de ese acontecimiento que se denominó el crimen de la calle Fontecilla. Cada uno de los capítulos da cuenta de un universo coherente en sí mismo, pero en su articulación queda plasmada la complejidad de la sociedad chilena al finalizar el siglo xix y despuntar el xx.
“Para tener libertad mayor en el campo de la cultura había que estar afuera”. Conversaciones con el intelectual colombiano Eduardo Gómez
Authors: Jaramillo Restrepo Sandra
Published: February 2020

Este texto visibiliza el intelectual, poeta y crítico de arte colombiano, Eduardo Gómez (Miraflores, 1932), como parte de la aquí llamada generación de la utopía. Esto es, aquella que en las décadas de 1960 y 1970 desplegó intensas y plurales relaciones entre la cultura y la política, tanto en Colombia como en el concierto internacional. El país andino, a través de sus artistas e intelectuales, también hizo a esa época en la que la perspectiva del cambio social era prioritaria y una de sus herramientas más importantes era precisamente la cultura.
Tras una presentación del tema, el texto compone para el conocimiento público un extracto de una larga conversación intergeneracional con el intelectual aquí visibilizado.

Analiza trendów atrakcyjności inwestycyjnej polskich miast na prawach powiatu w latach 2010 i 2017
Authors: Burzyńska Dorota , Jabłońska Małgorzata , Bartosik Grzegorz
Published: February 2020

Przedmiot badań: Atrakcyjność inwestycyjna jest zbiorem czynników, które powodują, że dany obszar wyróżnia się spośród innych i daje więcej korzyści z prowadzenia działalności potencjal­nym inwestorom aniżeli jest to w innych regionach. Rozwój inwestycji w regionach jest determi­nowany przez wiele czynników, na które w dużej mierze wpływ mają jednostki samorządu tery­torialnego. Szczególne miejsce w trójszczeblowej strukturze administracyjnej Polski odgrywają miasta na prawach powiatu, które realizując własną politykę rozwoju, mają wpływ na rozwój lokalnej przedsiębiorczości, a w tym poziom i jakość inwestycji.

Cel badawczy: Celem niniejszej pracy było określenie poziomu atrakcyjności inwestycyjnej w miastach na prawach powiatu w Polsce oraz analiza porównawcza otrzymanych wyników w latach 2010 i 2017.1

Metoda badawcza: W oparciu o podstawy teoretyczne, które pozwoliły na dogłębne zrozumie­nie zjawiska atrakcyjności inwestycyjnej, jak i dane pochodzące z Banku Danych Lokalnych Głównego Urzędu Statystycznego, metodą korelacyjno-wagową obliczony został wskaźnik, któ­ry pozwolił na porównanie atrakcyjności inwestycyjnej miast na prawach powiatu w latach 2010 i 2017. W tym celu zdefiniowano zestaw zmiennych oraz podzielono je na mikroklimaty, które przedstawiają najważniejsze obszary brane pod uwagę przez potencjalnych inwestorów przy wyborze miejsca nowych działań gospodarczych. Do przeprowadzonej analizy wykorzystano zestaw 17 zmiennych, które zostały pogrupowane w 5 mikroklimatach.

Wyniki: Przeprowadzenie analizy zawartej w niniejszym opracowaniu miało na celu stworzenie obrazu klimatu inwestycyjnego w przekroju całego kraju. Uzyskane wyniki pozwoliły stwierdzić, iż atrakcyjność inwestycyjna miast na prawach powiatu jest uzależniona w głównej mierze od polityki prowadzonej przez samorządy. Warunki geograficzne nie dają bowiem pewności, że re­gion będzie atrakcyjny dla inwestorów jedynie dzięki dobrej lokalizacji. Przykład mogą stanowić takie miasta jak Łódź, gdzie wzrost atrakcyjności inwestycyjnej jest w dużej mierze zasługą prze­prowadzonych działań rewitalizacyjnych, oraz Lublin, gdzie władze opracowały kompleksową strategie przyciągania inwestorów do miasta.
