Published: December 2019

In this study, two hormones 17β-estradiol (E2) and 17α-ethynylestradiol (EE2), and three phenolic compounds, bisphenol A (BPA), 4-N-nonylphenol (4-NP) and 4-tert-octylphenol (4-t-OP), were determined in surface water in the Cuautla River at the State of Morelos during the dry-season in Mexico. The endocrine disrupting compounds (EDCs) were extracted from water samples using solid-phase extraction (SPE) with end-capped C18, and then the extracts were chemically derivatized to TMS (trimethylsylane)-compounds and analyzed by gas chromatography coupled to mass spectrometry (GCMS). The most abundant compound was BPA (22.46 ± 30.17 ng L−1), followed by 4-t-OP (11.24 ± 11.76 ng L−1), 4-NP (7.53 ± 14.88 ng L−1), EE2 (2.37 ± 4.36 ng L−1) and E2 (0.97 ± 1.82 ng L−1). The residual amounts of target compounds could either reach stream surface water from direct domestic wastewater discharges, conventional wastewater treatment plant or can be a result from the use of agrochemicals in crop areas. The EDCs in Cuautla River exerted a high pressure on the aquatic ecosystem because their presences in surface water caused medium and high potential ecological risk. Besides, it was found that aquatic organisms were exposed to estrogenic activity.
Evaluation of Groundwater Potential by GIS-Based Multicriteria Decision Making as a Spatial Prediction Tool: Case Study in the Tigris River Batman-Hasankeyf Sub-Basin, Turkey
Authors: Çelik Recep
Published: December 2019

The Tigris River Batman-Hasankeyf region sub-basin drainage area is in the Upper Tigris basin and lies between the area where the Batman stream joins the river and the Yanarsu stream flows into the river. Intensive agricultural activities are carried out in this region, and irrigation is generally obtained from groundwater just as it moves away from the riverfront. The study area is a valuable basin for both Turkey and the Middle East. In this study, the effectiveness of the Geographic Information System (GIS)-based multicriteria decision-making (MCDM) analytic hierarchy process (AHP) as a spatial prediction tool was utilized in exploring the groundwater potential of the drainage area. In the analysis, eight hydrological and hydrogeological criteria were considered as influencing factors, namely, geomorphology, geology, rainfall, drainage density, slope, lineament density, land use, and soil properties. The weights of these criteria were determined through the AHP method; the Arc GIS 10.2.2 program and its submodules were used. The major findings of the study were that groundwater-potential index values of the basin were derived. Groundwater-potential-zone evaluation of the basin was obtained as follows: very poor (19%), poor (17%), moderate (34%), good (17%), very good (13%); and groundwater potential zone (GWPZ) maps of the sub-basin were created.
Examination of Blockage Effects on the Progression of Local Scour around a Circular Cylinder
Authors: Williams Priscilla , Balachandar Ram , Bolisetti Tirupati
Published: December 2019

An evaluation of scour estimation methods has indicated that the effects of blockage ratio are neglected in both scour modelling and development of new predictive methods. The role of channel blockage on the mechanism and progression of local scour is not well understood, and further analysis is required in order to incorporate this effect into scour estimation. In the present investigation, local scour experiments were carried out under varying blockage ratio. The results were compared with data from literature in order to explore the effects of blockage ratio (D/b, where D is the pier diameter, and b is the channel width) on equilibrium scour depth (dse/D, where dse is the depth of scour at equilibrium). It was determined that D/b had a small influence on both dse/D and the progression of scour depth (ds/D) when relative coarseness D/d50 < 100 (where d50 is the median diameter of sediment), and that the influence appeared to be amplified when D/d50 > 100. The efficacy of scour estimation methods used to predict the progression of local scour was also dependent on D/d50. A method of scour estimation used to predict dse/D was evaluated, and it was similarly found to be particularly effective when D/d50 < 100. In future work, further experiments and analysis in the range of D/d50 > 100 are required in order to establish the role of D/b under prototype conditions and to refine existing scour estimation methods.
Factors Influencing the Adoption of Water Conservation Technologies by Smallholder Farmer Households in Tanzania
Authors: Jha Srijna , Kaechele Harald , Sieber Stefan
Published: December 2019

In Tanzania, the increasing population coupled with climate change amplifies issues of food insecurity and negatively impacts the livelihoods of smallholder farmer households. To address these issues a range of water conservation techniques (WCTs) have been useful. However, the adoption of these WCTs in Tanzania has been limited due to many reasons. With the objective to better understand and identify the factors that significantly influence the adoption of WCTs in Tanzania, the study uses survey data from 701 smallholder farmer households and a bivariate logistic regression, to provide, for the first time, a comprehensive model for the adoption of WCTs in Tanzania that includes a range of individual, household, socio-economic, and farmer perception related variables (factors). The evaluation shows that 120 farmers (17.12%) adopted WCTs and finds the farmer perceptions of rainfall instability, household wealth, and food security to be crucial. The results suggest that policy interventions should encourage conservation behavior (especially when the rainfall is perceived to be uncertain), emphasize the economic and food security-related benefits of adopting WCTs, include strategies that make adoption of WCTs attractive to female-led households, attempt to reach greater number of farmers via social networks and provide better access to public funds for farmers.

Corrupção e desrespeito aos direitos dos índios brasileiros:
Authors: Reis de Macedo Michelle
Published: December 2019

A imprensa brasileira possui um papel importante na denúncia de casos de corrupção, sobretudo em instituições públicas. No entanto, toda matéria publicada em jornal passa por uma seleção, cujos critérios podem revelar interesses políticos, ideológicos e econômicos não explícitos. Portanto, a proposta é analisar os ditos e os silêncios da imprensa brasileira em relação aos problemas enfrentados por um grupo social específico, os índios brasileiros, devido ao mau uso da verba pública pelos órgãos indigenistas, bem como o precário cumprimento de sua função ao longo do século XX.
Delações e vida cotidiana no Brasil durante a ditadura civil-militar
Authors: Martins Cordeiro Janaina
Published: December 2019

A formulação de denúncias e delações contra indivíduos, grupos ou situações consideradas suspeitas tem sido prática recorrente na modernidade. Especificamente, as ditaduras e regimes autoritários do século XX incentivaram amplamente tais comportamentos. Este artigo propõe analisar as práticas delatórias no Brasil durante a ditadura civil-militar de 1964. Busca, sob este aspecto, compreender as formas a partir das quais cidadãos passaram a recorrer ao Estado e suas instituições com o objetivo de delatar autoridades locais, vizinhos, conhecidos, colegas de trabalho, etc. Considerando a pluralidade das práticas de delação, para além das denúncias fornecidas por informantes do regime, o artigo propõe analisar as motivações de “informantes eventuais” e, de maneira mais ampla, tem como objetivo compreender como o cotidiano da sociedade foi invadido e moldado pela linguagem e modus operandi da ditadura.
Alguns aspectos da Revolução Russa nas páginas das revistas ilustradas do Brasil Republicano
Authors: Casa Nova Maia Andrea , Carris Luciene
Published: December 2019

O artigo problematiza as diferentes leituras dos acontecimentos que levaram a tomada de poder pelos bolcheviques na revolução russa de 1917 presentes nas revistas ilustradas brasileiras, analisando as representações nas imagens e textos dos impressos que circulavam sobretudo na capital da recém proclamada República brasileira. As representações especialmente elaboradas pelas revistas ilustradas contribuíram para a formação de “visões” e diferentes interpretações sobre o ocorrido naqueles meses de guerra e revolução. Imagens e discursos que nos permitem analisar a construção de um discurso singular sobre a História nas páginas das revistas da República brasileira. Como as revistas Careta, FonFon, o Malho, Eu sei Tudo, A Leitura para Todos, Para Todos e A Revista da Semana apresentaram a Revolução Russa de 1917? Qual era o tipo de informação disseminada em tais periódicos? E em que medida a qualidade dessas informações se distanciava de outras fontes, como os jornais operários ou jornais diários da grande imprensa da época? Qual a contribuição dos periódicos ilustrados no entendimento de como a notícia e os fatos sobre a Rússia chegaram ao Brasil e eram difundidos? Quais as principais tópicas trabalhadas pelas revistas ao tratar do tema da Revolução Russa? O que se destaca?
Eleições na Primeira República:
Authors: M.R. Viscardi Cláudia , Fonseca Figueiredo Vitor
Published: December 2019

O presente artigo analisa as eleições realizadas na Primeira República (1889-1930), mais especificamente a participação da população nos pleitos presidenciais. A abordagem adotada difere de boa parte dos estudos já produzidos sobre a história política da primeira fase do regime republicano brasileiro. Interessa-nos compreender porque os cidadãos deixavam de participar do processo de escolha dos seus representantes. Durante o período votar não era uma obrigação, mas um direito a ser exercido aos que se interessassem. Essa característica impunha uma lógica diferenciada ao campo político e, em especial às campanhas. Cabia aos candidatos atrair os seus eleitores, o que nem sempre ocorria sob coação, como parte da historiografia já afirmou. Portanto, levar os eleitores às urnas constituía um desafio. Para os fins deste artigo foram analisadas quatro eleições presidenciais em quatro unidades federadas, por meio de pesquisa realizada sobre os Diários do Congresso, a Imprensa e dados demográficos históricos do IBGE

Sosyal Bilgiler Dersinde Değerler Eğitimi ve Diğer Duyuşsal Süreçlerde Ölçme ve Değerlendirme: Sorunlar ve Çözüme Yönelik Etkinlik Örnekleri
Authors: TAHİROĞLU Mustafa , ÇETİN Turhan
Published: December 2019

Bilindiği üzere, ölçme ve değerlendirme bilişsel, duyuşsal ve psikomotor kazanımlar olmak üzere üç alanda ele alınmaktadır. Bu alanlardaki bilişsel ve psikomotor kazanımlar, belli sınavlar veya etkinliklerle kolaylıkla ölçülebilirken, duyuşsal kazanımların ölçülmesi bu kadar kolay olmayabilir. Çünkü duyuşsal davranışların, kişiden kişiye farklılık gösterebileceği gibi kişinin o anki içinde bulunduğu koşullara göre de değişebileceği; bu yüzden de tek bir doğru veya yanlışın olmadığı savunulmaktadır.  Ayrıca kişinin, içinde bulunduğu duruma göre gerçek düşüncelerini yansıtmayabileceği de bilinmektedir. Bu ve benzeri durumlar, duyuşsal eğitiminin sonuçlarını ölçmenin zor ve zahmetli bir iş olduğunu göstermektedir. Ancak son zamanlarda alandaki gelişmeler, insanların duygularını ifade etme yollarının belirlenebileceğini ve duygu, değer, davranış arasındaki ilişkinin tespit edilebileceğini ortaya koymaktadır. Literatür incelendiğinde, duyuşsal eğitim ve ölçme süreçlerinin temelde birbirini takip eden benzer işlemlerden oluştuğu ve özellikle Sosyal Bilgiler Dersinde konunun önemli bir kısmını değerler eğitiminin oluşturduğu görülmüştür. Bu yüzden çalışmada; Sosyal Bilgiler Dersinde verilen değerler eğitimi ve diğer duyuşsal süreçlerin sonuçlarının değerlendirilmesine yönelik sorunların tartışılması ve bu sorunların çözümüne katkı sağlamak için örnek ölçme-değerlendirme etkinliklerinin hazırlanması amaçlanmıştır. Bu amaç doğrultusunda öncelikle ilgili alandaki ölçme-değerlendirme sorunları tespit edilmeye çalışılmıştır. Sonra duyuşsal eğitim süreçleri, değerler eğitimi süreçleri, duyuşsal ölçme-değerlendirme süreçleri, kişiyi tanıma teknikleri, vb. süreçlerden de yararlanılarak konuya yönelik ölçme-değerlendirme etkinlik örnekleri hazırlanmaya çalışılmıştır.

La construcción del bien en atmósferas antiéticas en La ciudad y los perros (1963)
Authors: Delgado del Aguila Jesús Miguel
Published: December 2019

Uno de los problemas planteados en la historia desarrollada de los protagonistas de La ciudad y los perros (1963), del escritor peruano Mario Vargas Llosa, es la presencia de una formación familiar mal constituida (padres agresivos, distanciamiento de cualquiera de ellos, favoritismo materno hacia el hijo, etc.). Esta base retrógrada provocó una limitación para cada uno de ellos: sus conductas no son corregidas, tienen comportamientos rebeldes o inhibidos, se sienten incapaces de afrontar la realidad con responsabilidad y terminan incluyéndose en el mecanismo dinámico de la violencia, ya sea como víctima o victimario. Para ello, se recurrirá al análisis literario, para abordar las conductas vinculadas con los personajes que poseen rasgos de violencia en su representación. Principalmente, las propuestas teóricas de Jacques Lacan, Slavoj Žižek y Mijaíl Bajtín revelan qué se entiende en la actualidad por practicar el bien en nuestra sociedad. A partir de esa conceptualización, se buscarán indicadores que permitan apreciar la procedencia de la mala formación del Jaguar, el Poeta o el Esclavo.
Lenguaje y extrañeza: una lectura psicoanalítica y gótica de “El cuervo” de Edgar Allan Poe
Authors: Marín Calderón Norman
Published: December 2019

Este artículo explora la relevancia teórica que lo ominoso freudiano (das Unheimlich) y la angustia lacaniana (l’ Angoisse) tienen para los estudios literarios góticos. Distinto de lo sublime y lo terrorífico, lo ominoso (o siniestro) se caracteriza por presentar elementos intrínsecamente familiares que producen, no obstante, miedo y repulsión, pero a pesar de ello, también generan fascinación. Para Freud, lo ominoso está relacionado con los mecanismos de la castración y la represión haciendo que lo más hogareño, lo cual ha quedado reprimido en lo inconsciente, retorne transformándose en algo extraño. Por su parte, Lacan explica el fenómeno de lo ominoso a partir del concepto de angustia, la cual emerge cada vez que un objeto que obligatoriamente debería estar velado aparece importunando al sujeto. Finalmente, todo este deambular teórico por los conceptos de lo siniestro y la angustia serán puestos a prueba a partir de una lectura gótica y psicoanalítica del poema “El cuervo” de Edgar Allan Poe en donde el elemento destacado será el lenguaje.
Ideas para un sueño. Cien bagatelas de Manoel Carlos Karam
Authors: Barrós Manuel
Published: December 2019

En esta oportunidad, Manuel Barrós presenta y traduce una importante selección de bagatelas del escritor brasileño Manoel Carlos Karam que, originalmente, fueron publicadas en el libro Godot é uma árvore (2015). Estas han sido seleccionadas porque representan parte fundamental de la poética de Karam, uno de los autores más originales y desconocidos de la literatura de lo absurdo en Brasil. Algunos de sus rasgos a resaltar son lo insólito, lo lúdico y la intertextualidad; todos ellos matizados con un sentido del humor muy crítico en su lectura de las literaturas y culturas brasileña, latinoamericana y universal. Cabe añadir que esta es la primera vez que Karam es traducido a otro idioma. Por ello, al publicar una versión bilingüe, el traductor difunde el estilo original de la obra de Karam y amplía el panorama que de la literatura brasileña se tiene en el Perú y en Latinoamérica.

The synthesis of (Bi1-xPbx)2Sr2Ca2Cu3O8+σ (x=0 and 0.4) bulk samples (hereafter called as Bi-2223) were completed by using solid-state reaction method. The Bi-2223 samples were subjected to calcination for 24 hours at 840°C, Then, the pelletized powder for both samples were sintered at 865°C for 48 hours. Each sample was exposed to high energy electron irradiation with a dosage of 100 kGray. Structural examination was conducted by using the Bruker D8-Advanced X-ray powder Diffraction (XRD). According to Bi-2223 indexed phase structure, the XRD patterns obtained shows that the samples, both Bi-2223 (x=0 and x=0.4) samples showed well-defined peaks and phase structure remains unchanged after the sample being exposed to the electron source. Measurement of the critical temperature, TC were obtained by using AC susceptibility technique and four-point probe. Bi/Pb (x=0.4) sample showed significant TC value compared to Bi/Pb (x=0) sample. Grain alignment in SEM micrographs show enhancement in their grain connectivity and also layering texture in irradiated sample which might lead to has better superconducting properties. In contrast, the impact of electron irradiation on its microstructure and consequently the TC was destructive in the Bi/Pb (x=0) sample.

Evolución y condiciones sanitarias de los Centros de Adorno Corporal de la Comunidad de Madrid (2005-2018)
Authors: Butler Sierra Mercedes
Published: December 2019

El adorno corporal agrupa prácticas que se caracterizan
por la ruptura o perforación de la barrera epidérmica
para la incorporación de tintas y/o pigmentos o joyas.
Esto implica posibles riesgos para la salud del cliente,
pero también del aplicador, si no se realizan por personal
suficientemente formado y con los medios y condiciones
higiénico- sanitarias adecuadas. La Comunidad
de Madrid publicó el Decreto 35/2005, que regula estas
técnicas y obliga a los centros donde se practican a registrarse.
En este trabajo se ha hecho una caracterización de
las empresas, en base a la información consignada en el
registro y la obtenida en las inspecciones. Un 85% de los
establecimientos tenían buenas condiciones higiénicosanitarias.
Se podría concluir que, en términos generales,
el sector se ha profesionalizado, disponiendo de aplicadores
formados y establecimientos con unas adecuadas
condiciones higiénico-sanitarias y estructurales.

A Educação Financeira e a Base Nacional Comum Curricular
Authors: Giordano Cassio Cristiano , Assis Marco Rodrigo da Silva , Coutinho Cileda De Queiroz e Silva
Published: December 2019

Este artigo discute as novas perspectivas para a Educação Financeira no Brasil com ênfase na publicação da Base Nacional Comum Curricular e o potencial dessas mudanças para a promoção do letramento financeiro. A abordagem metodológica é o estudo bibliográfico documental e o quadro teórico é a Educação Matemática Crítica, norteando a análise sobre as dimensões cultural, social, educativa e política que permeiam as discussões sobre Educação Financeira na Educação Básica Brasileira. Nossa questão de pesquisa é “Em relação aos Parâmetros Curriculares Nacionais – PCN, a Base Nacional Comum Curricular – BNCC apresenta avanços para o desenvolvimento da Educação Financeira Brasileira e promoção do letramento financeiro dos alunos?” Concluímos que sim.  Enquanto os PCN ignoram totalmente a Educação Financeira, garantindo apenas a presença da Matemática Financeira, a BNCC mantém a segunda e ainda amplia o espaço da primeira no currículo, propõe um trabalho centrado na realidade do aluno, tratando de problemas sociais e ambientais, estimulando o emprego de tecnologias digitais e o desenvolvimento do pensamento crítico.

A preocupação com estratégias que contribuíssem para o processo de ensino e aprendizagem de frações, levou a busca por artigos que contemplassem este conhecimento no ensino fundamental. Assim, a questão que norteou este trabalho foi: de que forma as pesquisas abordam propostas para o ensino de frações no ensino fundamental? Para tanto, foi realizado um levantamento de trabalhos publicados nos anais do Encontro Nacional de Educação Matemática (ENEM) e do Encontro Paranaense de Educação Matemática (EPREM). Constatou-se que há pesquisas que abordam as frações no ensino fundamental a partir de estratégias diversificadas e outras que apresentam considerações sobre diferentes fatores relacionados a esse conteúdo. Porém, foram encontrados poucos relatos de práticas consolidadas para efetivação do ensino das frações nos anos iniciais do ensino fundamental, o que evidencia que ainda há necessidade de mais trabalhos que ressaltem esses aspectos.

Del amor sublime en Aura
Authors: Pérez Martínez Manuel
Published: December 2019

Aunque la magia de Consuelo es doble (partenogénesis de Aura y anamnesis de Felipe), en términos de la ficción, sin embargo, esta magia tiene como base al amor. La belleza no resulta una explicación suficiente para el amor que Fuentes hace nacer entre el historiador y la bruja; pues si la belleza se anula, es necesario buscar otra razón que vaya más allá del hecho aparente que es la hermosura física: el amor sublime. En Aura, de Carlos Fuentes, tiene lugar el triunfo de la magia sobre la historia y el enfrentamiento de dos modelos de conocimiento: el académico y la imaginación.
