RESUMO O objetivo foi avaliar o efeito do uso de extrato de plantas sobre a resposta imune, o desempenho produtivo e a morfometria intestinal de frangos de corte desafiados com a vacina contra coccidiose. Foram utilizados 720 pintos de corte, machos, distribuídos em um delineamento inteiramente casualizado com quatro tratamentos e nove repetições de 20 aves cada. A partir dos 14 dias, as aves passaram a receber os tratamentos experimentais compostos por A – Dieta basal + Antibiótico promotor do crescimento (APC) ; B - Dieta basal + APC + desafio vacinal; C - Dieta basal + extrato de plantas, e D - Dieta basal + extrato de plantas + desafio vacinal. As aves dos tratamentos B e D receberam vacina oral contra coccidiose (vinte vezes a dose individual recomendada pelo fabricante). A adição de extrato de plantas à dieta de aves desafiadas com oocistos de Eimeria sp aumentou (p <0,05) a secreção de IgA pela mucosa intestinal. As lesões microscópicas da mucosa intestinal não foram influenciadas (p >0,05) pelo desafio ou pelo uso do extrato de plantas. O desafio com oocistos de Eimeria sp ou associado ao extrato de plantas resultou em menor (p <0,05) ganho de peso e pior conversão alimentar apenas na semana seguinte à inoculação. Os resultados obtidos mostraram que a adição de extrato de plantas à dieta de aves submetidas ao desafio vacinal aumentou a secreção de IgA pela mucosa intestinal e que a inclusão do extrato de plantas ou de melhorador de desempenho resultou em desempenho produtivo semelhante.

RESUMO O objetivo foi avaliar o efeito da densidade de alojamento sobre a incidência de pododermatite e características ósseas durante todo período de criação de frangos de corte. O experimento foi realizado em três aviários comerciais. Os pintos foram alojados no mesmo dia e distribuídos de acordo com três densidades: aviário A - 14.33 aves/m2, aviário B - 15.00 aves/m2 e aviário C - 15.66 aves/m2. Semanalmente 15 aves/aviário foram sacrificadas e as pernas e o pé direito de cada ave foram coletados. Foi avaliado o score macroscópico da área do coxim plantar de cada ave, caracterizando-os em: ausência de lesão (score A), lesão leve apenas no coxim plantar (score B), lesões graves e múltiplas (C). Em seguida, foi extraído o coxim plantar do pé e fixado em formol tamponado. As amostras foram submetidas aos procedimentos histológicos (medida da derme e epiderme). Os ossos das pernas foram submetidos ao ensaio de flexão à taxa de deformação. A imagem transversal da porção medial da diáfise óssea foi capturada e medidas a área, espessura e diâmetro do osso cortical. Os dados foram analisados pelo programa SAS. O aumento na densidade de alojamento resultou em maior incidência de lesões graves no coxim plantar, menor resistência óssea à quebra e área do corte longitudinal da tíbia aos 42 dias e diminuição da espessura do osso cortical aos 21 dias de idade das aves. O aumento da densidade de alojamento afeta negativamente as características ósseas e leva a maior incidência de condenações por pododermatite ao abate.
Seismic retrofit of slab-on-girder steel bridges
Authors: Jamshidi Morteza , Majid Taksiah A.
Published: April 2017

Thin steel infill plate has been proposed in the past as a ductile end diaphragm to reduce the transverse seismic demand in slab-on-girder steel bridges. However, a simplified method is required to promote the use of steel infill plate end diaphragms as a retrofit strategy. In this paper, the retrofitting strategy is based on the ductility reduction factor (Rμ) provided by the addition of steel infill plate. A step-by-step procedure is developed to calculate the ductility reduction factor which reduces the force demand on vulnerable substructure elements. In addition, this procedure is shown to give results that compare well with numerical data from finite-element analysis.
Generalised stage–discharge relationship for rectangular weirs
Authors: Bijankhan M. , Di Stefano C. , Ferro V.
Published: April 2017

Rectangular weirs, which are very common hydraulic structures used in irrigation channels as water measuring devices, can be used for measuring very small discharges as well as high flow rates. From a practical point of view, the availability of a unique stage–discharge formula that can be applied to different types of rectangular weirs would be of great practical importance. In this paper, Buckingham's theorem of dimensional analysis and the self-similarity theory are used to deduce the stage–discharge curves of different kinds of rectangular weirs such as slit and partially contracted weirs. The proposed formula is then calibrated using measurements from this investigation and experimental data from the literature. Compared with the available stage–discharge relationships, the results indicate that the proposed method can be used for the entire range of the ratio of weir width to channel width (i.e. both slit and partially contracted weirs) with acceptable accuracy.

Purpose. Determination of patterns of cenomanian-callovian groundwater complex chemical composition formation in Kyiv due to man-caused influence. Methodology. During the study, the following approaches were used: mathematical methods of hydrogeological data processing (normalization of groundwater chemical composition parameters, determination of mineral substances export man-caused flow capacity, regression analysis and exponential trending). For graphs construction Excel and Statistica programs were used. Findings. The regularities of cenomanian-callovian groundwater complex chemical composition changes in Kyiv during the 1980s–2010s, based on primary parameters, were investigated. Correlation between changes of study groundwater complex chemical composition normalized parameters and water intake intensity was analyzed. Regular increase of mineral substances content with water intake decrease was revealed. The capacity of man-caused flow of mineral substances export from study groundwater complex was estimated. It was determined, that the dynamics of mineral substances man-caused flow parameters with high correlation coincides with the dynamics of power generation in Ukraine. Temporal patterns of water quality parameters changes were defined. The rate constant of mineral substances man-caused flow parameters changes during the1980s–2010s was calculated. Originality. It was defined that cenomanian-callovian groundwater complex quality, used as potable water source for Kyiv population, is extensively determined by man-caused factors, such as industrial production and water intake intensity. Significant negative correlation (Kcor 0,6 – -0,85) between water quality normalized parameters value, mineral substances export value, water intake intensity and industrial production output (estimated by power generation in Ukraine) was revealed. Practical value. The resulting research exponential trends of dynamics of mineral substances man-caused flow parameters, especially calculated rate constants of their changes during the 1980s–2010s, can serve as an instrument of groundwater chemical composition prediction in conditions of intensive water intake. Principles of application of exponential regression together with correlation analysis procedures allow to reveal both groundwater chemical composition quality parameters connection with man-caused factors and temporal trends of their changes, and can be successfully applied to urban areas.

Published: April 2017

The paper focuses on the psychodynamic mechanisms of Capgras phenomenon, a rare and insufficiently studied mental disorder, which has not been paid much attention to in clinical psychology and psychiatry up to the present. Despite the fact that the phenomenon was described in 1923 it has not been properly studied yet, though it is widely spread in psychiatric and psychotherapeutic practice. The most important issue at present is to understand the underlying psychodynamic mechanisms, which can make psychotherapeutic work more effective. The paper contains several clinic cases, which can facilitate understanding of psychic peculiarities of patients suffering from the syndrome. Emphasis is put on the necessity to reveal the syndrome’s causes and the resources hidden in the unconscious as a potential possibility to overcome Capgras phenomenon.

En este trabajo se estudiaron las relaciones existentes entre la demanda biológica de oxígeno (DBO) y las variaciones de la acidez producidas durante el proceso de metabolización aeróbica de las aguas residuales domésticas. En una primera fase del proyecto se utilizaron soluciones patrón de glucosa y ácido glutámico y, en una segunda, muestras provenientes de la corriente influente de la Planta de Tratamiento de Aguas Residuales El Salitre, de Bogotá, Colombia. Se utilizaron botellas comerciales de color ámbar y 500 ml de capacidad nominal para incubar las muestras; para la captura del bióxido de carbono generado por la metabolización aeróbica de la materia orgánica en la fase acuosa se empleó una solución tampón concentrada; posteriormente, se determinó la cantidad de CO2 generado durante la incubación de las muestras mediante titulación con una base fuerte. Se encontró que la DBO de las aguas residuales domésticas podía medirse cuantificando la acidez durante el metabolismo de la materia orgánica contenida con ventajas comparativas frente al método estándar de incubación durante cinco días. © 2017.

Dimensionality of the PTSD Checklist in a Canadian Aboriginal Sample
Authors: MacLeod Melissa A. , George Julie , Tremblay Paul F. , Elton-Marshall Tara , DeWit David , Graham Kathryn , Wells Samantha
Published: April 2017

Background and Purpose: The PTSD Checklist–Civilian Version (PCL-C) is a widely used screening instrument measuring posttraumatic stress disorder (PTSD). However, to our knowledge, the factor structure of the PCL-C has not been examined in an Aboriginal population. Considerable research indicates that PTSD symptoms are characterized by 4 factors, with both the “King model” and the “Simms model” supported by the literature. Methods: Using confirmatory factor analysis on the PCL-C, we examined whether these models and the overall scale were supported in an Aboriginal community sample (N = 273). Results: The data supported both models. However, the 4 factors were highly correlated, providing some support for a 1-factor model as well. Conclusions: Our data support use of the PCL-C in Aboriginal health research.

Ecuador is a diversified country with great potential for tourism. The diversity can be seen in the variety of natural and cultural attractions found in the four natural regions. Orellana province is an home of five different indigenous nationalities. Each of these nationalities has its own language, customs and traditions. The indigenous nationalities of Shuar, Kichwa, and Waorani are located in the Francisco de Orellana canton. This canton has important natural and cultural attractions, which makes the development of a community-based tourism project viable. The geographical location of the communities of Atahualpa, Nantip, and Ñoñeno makes it feasible to design a tourism route, which would help these communities to share their natural and cultural richness. These communities have had difficulties in structuring their resources in a technical way. Therefore, this study aims to integrate all the touristic attractions in order to advertise them to the public to achieve sustainability and increase their competitiveness in the market. In order to achieve this goal, a feasible study was carried out to implement a community-based tourism route. Based on the market study, it was determined that there is a high demand of national and international tourists who would like to visit a tourism route in this canton. Also, there is a high demand to visit the flora and fauna found in the Amazon region of Ecuador. Three touristic packages were developed, which bring together all the communities. As a result, it makes them more competitive in the area. In conclusion, the implementation of a community-based route that uses touristic packages, would allow the direct participation of the people in the communities, the sustainable use of natural and cultural resources, and a fair and equitable distribution of the income generated by the touristic activities.

O artigo analisa, com estatísticas e por meio de crítica do filme Azul é a Cor Mais Quente (França, 2013), as características fundamentais nas produções audiovisuais eurocêntricas – hegemônicas e dominantes no panorama mundial – que instigam, perpetram, e perpetuam a anulação e/ou a negação do feminino. Bem como enraízam os estereótipos de gênero que permeiam as diversas culturas e sociedades globais. As estatísticas sobre mulheres empregadas nas produções audiovisuais, as teorias do cinema, da fotografia em movimento, e as análises críticas das teorias feministas do cinema são desenvolvidas como ferramentas para a pesquisa. A imagem é um instrumento poderoso de comunicação, assemelha-se ou confunde-se com o que representa. Visualmente imitadora (mimesis), ou reflexo, pode levar ao conhecimento, educar, ou enganar.

RECEITANDO FICÇÕES PARA AFLIÇÕES: a Farmácia Literária X Como Proust pode mudar sua vida
Authors: Tucherman Ieda
Published: April 2017

Este texto trata do estudo dos vínculos e dos afetos na subjetividade contemporânea. Nosso interesse é o de, sem desconhecer as pesquisas biotecnológicas, apontar que a cultura somática que começou a se desenvolver desde os anos 80, correlata de uma compreensão neuroquímica da subjetividade, atua reforçando um narcisismo pragmático e nos afastando do regime que alimentou nossos sistemas imaginários e simbólicos: a literatura. Com os exemplos do livro A cura pelo romance e Como Proust pode mudar sua vida buscamos demonstrar como, mesmo quando a literatura se faz presente, sua chave de leitura a aproxima da autoajuda. Resumindo: propomos que a crise das grandes narrativas, inclusive as literárias, é causa e efeito da crise dos afetos. No mesmo sentido defendemos a necessidade da perda de tempo e a prática do devaneio.

Ostreolysin A/Pleurotolysin B and Equinatoxins: Structure, Function and Pathophysiological Effects of These Pore-Forming Proteins
Authors: Frangež Robert , Šuput Dušan , Molgó Jordi , Benoit Evelyne
Published: April 2017

Acidic ostreolysin A/pleurotolysin B (OlyA/PlyB, formerly known as ostreolysin (Oly), and basic 20 kDa equinatoxins (EqTs) are cytolytic proteins isolated from the edible mushroom Pleurotus ostreatus and the sea anemone Actinia equina, respectively. Both toxins, although from different sources, share many similar biological activities: (i) colloid-osmotic shock by forming pores in cellular and artificial membranes enriched in cholesterol and sphingomyelin; (ii) increased vascular endothelial wall permeability in vivo and perivascular oedema; (iii) dose-dependent contraction of coronary vessels; (iv) haemolysis with pronounced hyperkalaemia in vivo; (v) bradycardia, myocardial ischemia and ventricular extrasystoles accompanied by progressive fall of arterial blood pressure and respiratory arrest in rodents. Both types of toxins are haemolytic within nanomolar range concentrations, and it seems that hyperkalaemia plays an important role in toxin cardiotoxicity. However, it was observed that the haemolytically more active EqT III is less toxic than EqT I, the most toxic and least haemolytic EqT. In mice, EqT II is more than 30 times more toxic than OlyA/PlyB when applied intravenously. These observations imply that haemolysis with hyperkalaemia is not the sole cause of the lethal activity of both toxins. Additional mechanisms responsible for lethal action of the two toxins are direct effects on heart, coronary vasoconstriction and related myocardial hypoxia. In this review, we appraise the pathophysiological mechanisms related to the chemical structure of OlyA/PlyB and EqTs, as well as their toxicity.
How Older Adults and their Families Perceive Family Talk about Aging-Related EOL Issues: A Dialectical Analysis
Authors: Egbert Nichole , Child Jeffrey , Lin Mei-Chen , Savery Carol , Bosley Tammy
Published: April 2017

For older adults, approaching end-of-life (EOL) brings unique transitions related to family relationships. Unfortunately, most families greatly underestimate the need to discuss these difficult issues. For example, parents approaching EOL issues often struggle with receiving assistance from others, avoiding family conflict, and maintaining their sense of personhood. In addition, discussions of EOL issues force family members to face their parents’ mortality, which can be particularly difficult for the adult children to process emotionally. This study explored aging issues identified by aging parents and their families as they traverse these impending EOL changes. Ten focus groups of seniors (n = 65) were conducted. Focus groups were organized according to race (African American/Caucasian), gender, and whether the older adult was living independently or in an assisted care facility. When asked open-ended questions about discussing aging and EOL issues with family members, participants revealed tensions that led us to consider Relational Dialectics Theory as a framework for analysis. The predominant tension highlighted in this report was certainty versus uncertainty, with the two sub-themes of sustained life versus sustained personhood and confronting versus avoiding EOL issues. For these data, there were more similarities than differences as a result of gender, race, or living situation than one might expect, although culture and financial status were found to be influential in the avoidance of EOL discussions. The results of this study help to provide additional insight into relational dialectics related to aging, EOL, and the importance of communication in facilitating family coping.

Successful 20-Well Stimulation Campaign in a Mature Oil Field in Myanmar
Authors: Shaoul J. R. , Tkachuk I.. , Chia D. J. , Nyo T.. , Eng J..
Published: April 2017

Hydraulic-fracturing technology is widely used to facilitate and enhance the recovery process from oil and gas reservoirs. Much worldwide experience has been gained in stimulating conventional and shale oil reservoirs; however, achieving good stimulation results in mature (depleted) oil fields with moderate permeability can be challenging and results can easily fall below expectations for a variety of reasons.

To narrow the gap between expected results and actual well performance after a successful fracturing treatment, it is very important to understand the reservoir characteristics and the actual reservoir potential. Despite the common opinion that stimulating mature, depleted wells is unprofitable, experience shows that stimulating such wells can still result in substantial and profitable production increases.

Twenty hydraulic-fracturing treatments were performed on wells in a mature onshore oil field in Myanmar, in Southeast Asia. These wells had never been fracture stimulated in the past, because of the moderate-to-high permeability of the reservoir. The stimulated wells have shown significant increases in initial incremental oil-production rate—on average, by a factor of two, which was still below the expectations. The treatments have effectively increased cumulative production and added to reserves. At the time of writing, the daily production rate from the 20 wells is actually increasing, rather than declining. This is likely caused by some kind of cleanup effect related to fracture stimulation in this highly depleted reservoir.

This paper discusses the challenges seen and the results obtained using hydraulic-fracture stimulation in a mature oil field. This case shows the importance of a proper candidate-selection method, which has contributed to successful stimulation and has improved oil recovery in this case.
Recurrent Selection for Improved Germination under Water Stress in Russian Dandelion
Authors: Hodgson-Kratky Katrina J.M. , Stoffyn Olivier M. , Wolyn David J.
Published: April 2017

Russian dandelion [Taraxacum kok-saghyz (TKS)] is a promising candidate for introducing natural rubber production into North America. Seeds normally germinate in a humid microenvironment, such as the thatch layer of a lawn or under a canopy of grass; however, 5% to 15% establishment is often observed on bare soil, presumably due to water stress. Phenotypic selection and half-sib family recurrent selection were conducted for three cycles to improve germination in vitro, under low osmotic potential (Ψs), using a polyethylene glycol (PEG) solution. Populations were then tested for establishment on bare soil in the greenhouse and field. Germination under water stress in vitro increased from 5.8% for the cycle 0 (C0) population to 40.8% and 47.8% for the C3-phenotypic and C3-half-sib family populations, respectively. Soil establishment in the greenhouse and field was improved up to two- and 4-fold, respectively, compared with the C0, in two of four greenhouse experiments and three of eight field experiments. Overall, recurrent selection for germination under water stress in vitro has potential to improve establishment in the field and can be incorporated into current breeding programs to support the overall goal of creating cultivars with high-rubber yield.

Starch accumulation is important during com development. ADP-glucose pyrophosphorylase (AGPase) is the rate-limiting enzyme in starch synthesis. AGPL is the large subunit of AGPase. Here, we isolated and characterized the large subunit of AGPase gene GhAGPL1 in gladiolus (Gladiolus hybridus). GhAGPL1 was highly expressed in sink organs (cormels and corms). The expression of GhAGPL1 was induced by glucose, sucrose, and mannitol, and it was repressed by abscisic acid (ABA). Overexpression of GhAGPL1 in the arabidopsis (Arabidopsis thaliana) apl1 mutant resulted in complementation of AGPase activity and thus starch synthesis. Silencing GhAGPL1 in gladiolus decreased the transcript level of GhAGPL1 and GhSus, and resulted in the reduction of AGPase activity and starch content in gladiolus corm and cormel. Meanwhile, sucrose content was higher in GhAGPL1-silenced corm. Surprisingly, silencing GhAGPL1 in gladiolus produced smaller corms and fewer number of cormels. Overall, GhAGPL1 contributed to the quality and quantity of gladiolus corms and cormels.

Background & Aims. T-cell receptor excision circles (TREC) and к-deleting recombination excision circles (KREC) are extrachromosomal DNA segments generated during V(D)J recombination process that characterize the diversity of the antigen repertoire of T- and B-cells. The aim of our study is to identify the prognostic value of the excision circles in the chronic lymphocytic leukemia (CLL) setting. Methods. The excision circles' levels were assessed by means of real time PCR in 109 patients with high-risk CLL and 16 matched healthy individuals. Results. KREC levels were significantly (p < 0.001) lower in CLL patients vs. the reference group. TREC levels were lower in groups with unmutated status of immunoglobulin heavy chain variable region genes (p < 0.05) and 11q deletions (p < 0.1). Moreover, the KREC levels were higher in NOTCH1 mutation carriers than in noncarriers (p < 0.05). The comparison of treatment outcomes demonstrated a correlation between a high TREC level and achievement of complete remission. The prognostic value of the bio-marker was confirmed by ROC-analysis: AUCTREC = 0.713 (p = 0.001) Conclusion. Association between excision circles' le' and clinical/laboratory CLL prognostic factors, as well complete remission achievement, makes possible the plementation of the test for early prediction of the treatm outcome.

Aim. To evaluate the relevance of the positron-emission therapy (PET) for optimization of the therapy of advanced Hodgkin's lymphoma (HL) using the intensive EACOPP-14 program. Materials & Methods. 91 patients with advanced HL (IIX-IIE, III-IV) received the treatment according to the “ЛХМосква1-3” protocol over the period from November 2009 to February 2015, and then the treatment was analyzed. The median age was 29 years (range: 17-50); there were 42 men (46.3 %) and 49 (53.7 %) women. The treatment included 6 cycles of polychemotherapy according to the regimen ЕА(50)С0РР-14 ± radiation therapy. The radiation therapy was performed in 66 patients (72.5 %) after the completion of the chemotherapy. The cumulative focal dose was 30 Gy onto the areas of residual lesions and/or initially large tumor masses. Results. PET performed during the initial HL diagnosing permited to identify new areas of neoplastic lesions without changes in staging and treatment scheme, as well as specify areas and field size of planned radiation consolidation. The paper confirms the prognostic value of the intermediate PET in patients with advanced HL during the intensive first-line chemotherapy. The intensive therapy at the beginning of the treatment program is associated with higher chances for survival for patients with extremely unfavorable prognosis. After completion of the drug therapy, negative PET findings had a higher prognostic value, than the positive ones. The analysis of the relevance of residual tumor dimensions in the PET negative group demonstrated that the relapses were more common, if the residual tumor was more than 4.5 cm (according to CT findings). Conclusion. This study confirmed that it reasonable to discuss the discontinuation of the radiation therapy in patients with advanced HL, negative PET findings and small (< 2.5 cm) residual tumor after the intensive ЕАСОРР-14 program. This tactics permits avoiding a number of delayed complications.
Chromothripsis in Oncology: Literature Review and Case Report
Authors: Mamaev N.N. , Gindina Tat'yana Leonidovna , Boichenko E.G.
Published: April 2017

The article presents a clinical case and literature review dwelling on the recently discovered chromothripsis phenomenon in oncology. Chromothripsis is a type of complex genome changes when a chromosome is first torn into dozens and even thousands of fragments, and then these fragments are bound in a random manner. Sometimes, several chromosomes are involved in the restructuring. As a result, genome mutant zones are formed which trigger malignancies and congenital diseases. In other words, the use of certain methodological approaches (multicolor fluorescence in situ hybridization, SKY technique, and some others) permits to observe under a microscope the splitting of two or more chromosomes and further reunification of these fragments into new unusual two- or multicolor structures, chromosomal markers. Chromothripsis is a rare phenomenon with a peculiar pattern observed in clones of cells of various tumors including hematopoietic and lymphoid tissue malignancies. There are published data on a higher incidence of this phenomenon in patients with myelodysplastic syndromes and bone tumors. TP53 gene mutations play an important role in the development of chromothripsis. The use of paired-sequencing DNA or SNP approaches in oncology is promising both in theoretical and clinical application. The first subject cohort should include patients with TP53 and MLL gene mutations, complex chromosomal aberrations, EVI-1 gene overexpression, and some others. The article presents the chromothripsis phenomenon in an 8-month-old girl with M7 acute myeloid leukemia.
LA EDUCACIÓN FÍSICA Y EL DEPORTE EN COLOMBIA: UN DIÁLOGO ENTRE LA RELIGIÓN Y LA PEDAGOGÍA EN LOS INICIOS DEL SIGLO XX
Authors: Rúa Penagos Jonathan Andrés , Pinillos García Jesús María
Published: April 2017

Al indagar por las relaciones entre la religiosidad, la espiritualidad y los discursos pedagógicos sobre la Educación Física y el Deporte en Colombia, durante los inicios del siglo XX, a partir de la lectura e interpretación de los textos Elementos de pedagogía moderna (Restrepo & Restrepo, 1911) y Cultura física, moral y mental (Nuñez S., 1936), se encontró que todas estas categorías integran una red que adquiere un sentido teológico. De esta manera, los componentes pedagógicos y religiosos poseen un mismo sentir y actuar. Es así, entonces, como estos saberes constituyen un estatus propedéutico y son implementados como medio para el fortalecimiento de las facultades humanas, entre ellas la voluntad, y el fortalecimiento de la relación Dios-hombre-otro, en búsqueda de la felicidad humana.
RELACIÓN ENTRE EL CONCEPTO DE VERDAD Y EL CONCEPTO DE INTERPRETACIÓN
Authors: Pino Montoya José Wilmar
Published: April 2017

La filosofía hermenéutica de Gadamer está fundamentada en la teoría de una verdad interpretativa, ya que según este autor la verdad solo puede ser encontrada en la relación que se establece entre el ser como intérprete y la cosa o la realidad que este interpreta, de este modo, nace una nueva manera de acercarse al conocimiento bajo la premisa de que el problema de la verdad es un  eminentemente interpretativo. En otras palabras, para el hombre, la realidad es verdadera en cuanto esta es interpretada por el ser en el estar ahí, de este modo, lo que el hombre dice de lo que conoce, es distinto de su opinión o es distinto de sí mismo. No habla de sí, sino del mundo en el que habita y esto es lo que hace que lo que diga de este no sea tenido como verdadero o falso.
ACTORES Y ESPACIOS EDUCATIVOS: CRÍTICAS Y PROPUESTAS DE HENRY GIROUX Y PETER MCLAREN
Authors: Paredes Oviedo Diana Melisa
Published: April 2017

En este artículo se revisan algunas concepciones que Henry Giroux y Peter McLaren ofrecen acerca de los actores y los espacios educativos. Profesores y estudiantes, desde la pedagogía crítica, son considerados transformadores activos de la cultura dispuestos al intercambio y la colaboración. No obstante, hay un cambio en la propuesta de McLaren, quien postula una pedagogía revolucionaria en donde la escuela se asume como un escenario de colisión y sus actores profundizan la contradicción entre la escuela y la cultura dominante. Se trata de dar cuenta de los retos a los que hace frente la educación, expuesta a la dominación capitalista, de acuerdo a lo que expresan ambos autores.
EL REY SALOMÓN: IMAGEN TRASGRESORA DE LEYES RELIGIOSAS Y CIVILES PRESENTE COMO CRÍTICA EN EL LIBRO DEL CANTAR DE LOS CANTARES
Authors: Villadiego Rozo Adolfo Enrique
Published: April 2017

El presente artículo recoge los avances en la investigación sobre el libro sagrado del “Cantar de los Cantares” y la imagen contradictoria que el texto presenta del rey Salomón. Este personaje bíblico, símbolo de sabiduría, aparece como la imagen trasgresora de leyes religiosas y civiles apartándose de la idea de monarca modelo que las interpretaciones alegóricas de la Biblia le han atribuido. Desde una perspectiva hermenéutica y apoyándonos en planteamientos socio-críticos, se busca dilucidar aspectos clave que devela el poema sobre las actuaciones del rey Salomón, todas estas contrarias a los que las leyes de la teología deuteronómica proponían.

En el siglo V a. de C. la ciudad griega se ve atravesada por una serie de transformaciones sociales, políticas,culturales y mentales ligadas al surgimiento de la democracia ateniense. La tragedia nace unida a la par deésta y surge principalmente como forma de festividad religiosa y pretendía la unificación y la educación delciudadano ateniense. Esquilo y Eurípides son dos grandes exponentes de la tragedia griega, ambos desdesus posturas, muestran en sus obras la concepción de democracia que tenían, las transformaciones queésta iba teniendo, la manera de ver el mundo y de expresarlo. En Esquilo se ve una visión optimista y deesperanza en su pueblo que progresa paulatinamente; en Eurípides un marcado patriotismo y compartetambién la fe en su ciudad, pero a medida que la democracia se va transformando su amor y su fe en laciudad se convierten en amargura y decepción.
