O artigo Artes e currículo: trajetórias e narrativas docentes estuda os programas curriculares na área de Artes Visuais vigentes em instituições públicas de ensino das secretarias municipal, estadual, federal e também em (algumas) instituições privadas na cidade do Rio de Janeiro. O entendimento acerca dos programas curriculares de Artes Visuais torna-se pertinente para a formação e interesse acadêmico-profissional de pesquisadores envolvidos na Iniciação Científica (PIBIC) de uma universidade pública. Tais currículos voltados à educação básica e institucionalizados nas respectivas escolas selecionadas na pesquisa são percebidos através das seguintes vias metodológicas: das orientações curriculares - entendidas como apoio metodológico para os docentes - às entrevistas, propriamente ditas, com alguns docentes de certas instituições sobre suas trajetórias cotidianas - isto é, como os docentes articulam artisticamente o repertório imagético da historiografia da arte e da cultura visual, por exemplo, nos planejamentos de curso. Os resultados aqui por ora apresentados prosseguem com a finalidade de impulsionar a pesquisa autoral docente voltada à dinamização curricular na área de Artes Visuais na educação básica, considerando-se as especificidades das diferentes realidades escolares e as urgências cotidianas do imaginário cultural dos discentes na atualidade.

Authors:   Universidade do Estado de Santa Catarina (UDESC), Florianópolis, SC, Clemencio Maria Aparecida
Published: October 2019

O presente artigo analisa possíveis interseções entre currículo, diversidades e ações afirmativas no espaço acadêmico; tendo como ponto de partida os novos sujeitos, presentes no espaço de instituições públicas de ensino superior, com a institucionalização da política de ações afirmativas por meio das cotas e também via legislação: lei 10.639/2003 - 11645/2008. São corpos, culturas, valores e identidades circulando num espaço e tempo que antes era de certo modo restritivo para estes novos sujeitos. Surgem com as ações afirmativas, no sentido de superar desigualdades, que tem se mantido para alguns indivíduos, como raça, sexo, deficiência, influindo sobremaneira na definição de oportunidades no ingresso e desempenho educacional, no mercado de trabalho, no progresso na carreira e na participação na vida política e de gestão pública. As reflexões foram norteadas com base na bibliografia e documentos sobre o tema. Como resultado observa-se um campo em constantes disputas entre as construções, desconstruções do currículo normatizado e as alterações epistemológicas na produção de conhecimento nos diferentes cursos de formação universitária.

Published: October 2019

Los objetivos del estudio fueron identificar los perfiles motivacionales de estudiantes universitarios y evaluar sus diferencias en cuanto a la satisfacción académica. Los participantes fueron 882 estudiantes con edades comprendidas entre los 17 y 50 años, procedentes de nueve universidades chilenas. Los perfiles motivacionales se identificaron mediante análisis de conglomerados, siguiendo la combinación de métodos jerárquicos y no jerárquicos. El análisis de conglomerados se realizó incluyendo las siguientes variables motivacionales: (1) motivación autónoma, (2) motivación controlada, (3) percepción de apoyo a la autonomía, y (4) percepción de control de la autonomía. Las diferencias entre los perfiles se evaluaron a través de la prueba Anova unifactorial, considerando el cálculo del tamaño del efecto y el análisis post-hoc de Games-Howell. Los resultados del análisis de conglomerados apoyaron una solución de cuatro perfiles motivacionales: mala calidad (n = 167), baja cantidad (n = 144), buena calidad (n = 333), y alta cantidad (n = 238). Además, los estudiantes agrupados en los perfiles con mayores niveles de autonomía para el aprendizaje, presentaron los niveles más altos de satisfacción académica. Como conclusión, se destaca la importancia que tienen los factores motivacionales para facilitar el desarrollo del bienestar de los estudiantes universitarios.

The aims of the study were to identify the motivational profiles of university students and to assess their differences according the academic satisfaction. The participants were 882 students aged 17 to 50, from nine Chilean universities. Motivational profiles were identified by cluster analysis, following the combination of hierarchical and non-hierarchical methods. The cluster analysis was perform including the following motivational variables: (1) autonomous motivation, (2) controlled motivation, (3) perception of autonomy support, and (4) perception of autonomy control. The differences among the profiles were assessed through the one way Anova test, considering the effect size calculation, and the Games-Howell post-hoc analysis. The cluster analysis results supported a four motivational profiles solution: poor quality (n = 167), low quantity (n = 144), good quality (n = 333), and high quantity (n = 238). Moreover, students grouped into profiles with higher levels of autonomy for learning, presented the highest levels of academic satisfaction. In conclusion, the importance of motivational factors to facilitate the development of university students’ well-being is highlighted.

Published: October 2019

Las organizaciones enfrentan el reto de gestionar una fuerza laboral multigeneracional con características propias que difieren en el valor que le otorgan al trabajo. La incorporación al mercado laboral de las generaciones más jóvenes hace imprescindible el estudio de sus diferentes actitudes hacia el trabajo en comparación con las generaciones antecesoras. El propósito de la investigación fue analizar a través del constructo de la ética protestante las diferencias existentes en las actitudes hacia el trabajo de cuatro generaciones (Baby Boomers, Generación X, Generación Y, y Generación Z).

La muestra de 624 participantes ecuatorianos (BB 11.2%; GX 11.2%, GY 58.5% y GZ 19.1%) se agrupó por cohortes. Se aplicó el Cuestionario Multidimensional Ética del Trabajo (MWEP). Los resultados mostraron que los BB y la GX tiene una mayor creencia en la importancia del trabajo y más tolerancia a la utilización improductiva del tiempo de trabajo que las generaciones Y y Z. En el aplazamiento de las recompensas la GZ muestra puntuaciones superiores a las obtenidas por los BB, GX y GY. No se encuentran diferencias significativas en las dimensiones de autoconfianza, ocio y moralidad-ética.

Enterprises face the challenge of managing a multigenerational workforce which has its characteristics that differ in the value they grant to work. Incorporation of younger generations into the labour market requires to study all their attitudes towards work, contrasting them with previous generations. The purpose of this research was to analyse, through the Protestant Ethic construct, the differences of four age groups in attitudes towards work (Baby Boomers, Generation X, Generation Y, and Generation Z).

Cohorts grouped the sample of 624 Ecuadorians (BB 11.2%; Gen X 11.2%, Gen Y 58.5% and Gen Z 19.1%). The Multidimensional Work Ethic Profile (MWEP) was applied. The results showed that BB and Gen X believe more in the importance of work than generations Y and Z. At the same time, BB and Gen X are more tolerant to the unproductive use of time than generations Y and Z. Gen Z has higher scores than BB, Gen X and Gen Y in the postponement of rewards dimension. Besides, there are no meaningful differences in self-reliance, leisure and morality/ethics dimensions.

Calibration
Authors: Sander Lane C.
Published: October 2019

In the context of chemical metrology, calibration is the process of relating a
known quantity of an analyte to the corresponding measured instrumental response
through a mathematical relationship. Calibration permits the assignment of analyte
levels in unknown samples based on the known levels of the calibrants. Details of
the calibration model are important to achieve accurate results. Several common
approaches are used in calibrating methods. Most frequently, calibration models are
based on linear instrumental response, with mathematical models that include zero
intercept, fixed intercept, unconstrained (fitted), and bracketed models. When
instrumental response is nonlinear, a linear model may still provide accurate
results if the calibration range is sufficiently limited. This presentation will
provide an overview and application of various calibration models, with
recommendations of ways to improve measurement accuracy. Examples are presented that
illustrate advantages and disadvantages for each of these models as applied to low
level samples and to unknowns with levels that span several orders of
magnitude.
Machine translation and author keywords: A viable search strategy for scholars with limited English proficiency?
Authors: Bowker Lynne
Published: October 2019

Author keywords are valuable for indexing articles and for information retrieval (IR). Most scientific literature is published in English. Can machine translation (MT) help researchers with limited English proficiency to search for information? We used two MT systems (Google Translate, DeepL Translator) to translate into English 71 Spanish keywords and 43 French keywords from articles in the domain of Library and Information Science. We then used the English translations to search the Library, Information Science and Technology Abstracts (LISTA) database. Half of the translated keywords returned relevant results. Of the half that did not, 34% were well translated but did not align with LISTA descriptors. Translation-related problems stemming from orthographic variation, synonymy, differing syntactic preferences, and semantic field coverage interfered with IR in just 16% of cases. Some of the MT errors are relatively “predictable” and if knowledge organization systems could be augmented to deal with them, then MT may prove even more useful for searching.
Sobre Dewey, jogos digitais e ensino de História
Authors: Pedrosa Stella Maria Peixoto de Azevedo , Soares Kauan Pessanha
Published: October 2019

O artigo associa a filosofia progressista de John Dewey, talvez o mais influente filósofo da educação no século XX, às concepções de jogos digitais e ao processo ensino-aprendizagem da História, considerando o jogo como uma possibilidade para o ensino dos conteúdos curriculares desta disciplina. Dewey defendeu a afinidade de todo conhecimento com o conhecimento prévio e, em termos historicistas, via a disciplina História como um produto do desenvolvimento histórico. Em sua perspectiva, para a compreensão de qualquer porção do conhecimento e sua relação com um indivíduo ou sociedade, deve-se entender sua história e, nesse sentido, considera o currículo organizado como uma história reencenada e cuidadosamente selecionada. Deste modo, os jogos digitais podem contribuir para o ensino dos conteúdos curriculares de História, visto que muitas de suas temáticas envolvem, de forma lúdica, importantes fatos históricos da humanidade, proporcionando o contato e ampliando o interesse pelo conhecimento histórico. Sob o enfoque deweyano, buscando-se integrar a “vida real” com as atividades escolares, discute-se de que modo os jogos digitais podem colaborar para que suas narrativas sejam relacionadas ao processo de ensino-aprendizagem. Em síntese, no artigo a perspectiva de Dewey é relacionada às concepções de jogos digitais e ao ensino da História, sendo, o jogo apresentado como uma possibilidade para a aprendizagem da História.
Ensino de dança na escola: desafios e perspectivas na visão de professores
Authors: Batalha Cecília Silvano , Cruz Giseli Barreto da
Published: October 2019

O presente estudo trata de uma pesquisa, desenvolvida no Estado do Rio de Janeiro, cujo objetivo consistiu em compreender como professores com formação superior em dança, que atuaram ou estão atuando na educação básica, no contexto da escola pública, concebem o ensino de dança e, além disso, o que fazem (se fazem) a favor da sua inserção enquanto área de conhecimento no currículo escolar. A abordagem se atém a parte dos resultados obtidos, detendo-se especificamente nos aspectos referentes à inserção da dança no currículo escolar, considerando quatro eixos analíticos: i - produção do conhecimento por meio do corpo; ii - possibilidade de trabalhar questões sociais e humanas; iii - questões multiculturais presentes na inserção da dança no currículo; iv - dificuldades estruturais para o ensino de dança na escola. O referencial teórico baseia-se em Cochran-Smith e Lytle (1999; 2002), Gauthier (2006) e Schön (2000); Canen/Ivenicki (2012; 2014); Marques (2010a; 2011; 2012); Strazzacappa (2010); Strazzacappa e Morandi (2012). Metodologicamente, adota-se a análise documental e a entrevista semiestruturada. Os resultados da pesquisa indicam que a inserção da dança no currículo é um desafio evidente para os professores, ainda que se reconheça que este ensino possa ser um espaço potente para a produção do conhecimento por meio do corpo, possibilitando uma formação mais abrangente.
Por que Black Mirror dá muito o que pensar?
Authors: Santaella Lucia , Gabriel Martha
Published: October 2019

Já na sua primeira temporada, a série Black Mirror ganhou grande popularidade. As razões para isso são muitas. Entre elas, vale a pena destacar a maneira distópica com que a narrativa desenvolve as questões relativas ao futuro das tecnologias a partir de sinais que já se deixam ver no presente. Para isso, os episódios fazem uso da hipérbole, ou seja, o exagero no tratamento dos temas escolhidos. A internet está repleta de sites e blogs que comentam e buscam as interpretações mais justas para cada um dos episódios que muitas vezes se engendram de maneira bastante engenhosa. O objetivo deste artigo é comparar a exacerbação a que a série conduz os temas tratados com a estratégia composicional dos contos de terror de Edgar Allan Poe. Com isso, pretende-se evidenciar um dos pontos mais fundamentais da montagem narrativa da série de modo a subsidiar sua utilização em contextos educacionais.
Dotando robôs com habilidades socioemocionais: presente, futuro e implicações éticas
Authors: Jaques Patricia
Published: October 2019

Nesse artigo busco discutir os impactos de robôs (em software ou hardware) dotados de habilidades socioemocionais. Para isso, uso como cenário ilustrativo o episódio “Volto Já”, da segunda temporada da série de televisão “Black Mirror”. Nesse episódio, Martha compra um robô que simula a personalidade do seu falecido marido, aprendida através das interações dele em redes sociais. O episódio trata das relações de afeto com robôs, justamente o tema que pretendo abordar, me focando nas emoções. Para tanto, primeiramente, apresento o estado da arte nas pesquisas em Computação Afetiva que envolvem robôs que são capazes de detectar emoções de diversas formas e responder a essas emoções para interagir de maneira mais antropomórfica. Posteriormente, abordarei potenciais impactos desse tipo de tecnologia na vida de humanos e no seu bem-estar e possíveis implicações éticas. Finalizarei esse artigo discutindo sobre como as tecnologias podem ser empregadas para aprendermos mais sobre nossos afetos.

Refletimos, com base em nossa pesquisa (SANTOS et al, 2015), as implicações provocadas na educação através da possibilidade de novas práticas pedagógicas no processo de aprendizagem na escola do século XXI. Também utilizamos episódios da série Black Mirror para enriquecer nosso debate sobre a aprendizagem em tempos onde os conceitos de objetos inteligentes e ciborgues já estão presentes.
Tecnologias digitais, espetáculo e violência na escola: uma análise de “Urso Branco”
Authors: Casagrande Ana Lara , Costa Aliana França Camargo , Fernandes Terezinha
Published: October 2019

O presente artigo se propõe a analisar as práticas de violência mediadas por aparatos tecnológicos no ambiente escolar, a partir do episódio intitulado Urso Branco, parte da série Black Mirror, da Netflix. Nesse episódio, há uma narrativa que se desenvolve em meio a um contexto de sadismo coletivo acerca da punição da personagem central, registrado pelos aparelhos celulares. Partimos do pressuposto de que a relação com a câmera é fundamental para a compreensão do registro passivo da violência e seu compartilhamento em redes. A abordagem deste texto é qualitativa e tem como eixos de desenvolvimento: o cenário mediado pelas tecnologias digitais; episódios de violências escolares; discussão sobre violência e conflito; o papel da escola e dos letramentos digitais em uma perspectiva social e abordagem crítica na educação. Nota-se que as práticas sociais, interfaceadas por produções e compartilhamentos de mensagens transmidiáticas, circulam fugaz e velozmente pela rede, o que demanda reflexão sobre as práticas de ensino docente, o papel da escola e a aprendizagem com o uso de tecnologias digitais, na ótica da repulsa às ocorrências de violência escolar, que infringem os direitos humanos, sociais e de acesso ao conhecimento de outrem.
“Black Mirror” e aprendizagens em rede: distopia, retrotopia e utopias em vivências (trans)formadoras na educação
Authors: Bruno Adriana Rocha , Silva Judilma Aline , Almeida Júnior Sebastião Gomes
Published: October 2019

O presente artigo apresenta três experiências de pesquisa desenvolvidas pelo Grupo de Pesquisa Aprendizagem em Rede, fomentadas com episódios da série de TV britânica “Black Mirror - BM”. Tendo como objetivo os estudos da cultura e educação digitais, a primeira vivência (trans)formativa se deu no interior do grupo de estudos, seguida de outra que envolveu o grupo e estudantes da Faculdade de Educação e uma última, com jovens que cumprem medidas sócioeducativas em regime semi-aberto. Sob o viés teórico de estudos recentes da cibercultura, destacam-se conceitos tratados por Pierre Lévy (1999, 2014) e por André Lemos (2018), em diálogo com conceitos de distopia (JACOBY, 2007), retrotopia (BAUMAN, 2017) e utopia (FREIRE, 2006a). A análise, em meio a pesquisa narrativa (CLANDININ e CONNELLY, 2011), considerou que no mundo atual coexistem movimentos

Rede social e comunicação ubíqua: o que podemos aprender com Black Mirror?
Authors: Couto Junior Dilton Ribeiro , Santos Rosemary dos , Velloso Luciana
Published: October 2019

Este texto busca tecer reflexões em torno de práticas sociais mediadas pelo digital em rede retratadas no episódio intitulado Queda Livre da série Black Mirror. A proposta é discutir a relação entre interconectividade, popularidade e visibilidade na era da comunicação ubíqua com a intenção de ressignificar nossa própria experiência humana, que vem sendo cada vez mais mediada pelos processos comunicacionais digitais. Buscar inspiração na ficção de Black Mirror pode se constituir como um caminho potente para refletirmos sobre nossa humanização numa era marcada pela intensa produção e compartilhamento de dados entre usuárias/os geograficamente dispersas/os. Para além do caráter ficcional da série e das situações expressas no episódio, há ali um alerta para os extremos a que o uso dos dispositivos digitais pode nos levar, fazendo-nos refletir sobre a importância de se colocar em prática uma educação que amplie nossa visão sobre o potencial da interconectividade e seus desdobramentos. Que esses novos fenômenos ciberculturais nos permitam tecer reflexões profícuas para uma melhor compreensão das práticas sociais contemporâneas, pelas relações que vimos estabelecendo com as redes sociais, com a emergência da comunicação ubíqua e com a ressignificacão de novas experiências sociais que emergem atravessadas pelo digital em rede na vida cotidiana.
Realidade aumentada na escola: experiências de aprendizagem em espaços híbridos
Authors: Bassani Patrícia Brandalise Scherer
Published: October 2019

As tecnologias de realidade aumentada possibilitam experiências em espaços híbridos, misturando o físico e o virtual por meio de representações tridimensionais. Este estudo tem por objetivo compartilhar práticas educativas em realidade aumentada desenvolvidas no contexto escolar e refletir sobre o envolvimento e a participação dos alunos na criação desses espaços híbridos. O estudo, de natureza aplicada e abordagem qualitativa, se apoia no método da Cartografia. Os dados foram produzidos no contexto do projeto Ambientes de Aprendizagem na Web desenvolvido na Universidade Feevale. Durante os anos de 2017 e 2018 foram propostas e desenvolvidas nove práticas educativas com o uso dos aplicativos Quiver e HP_Reveal. As práticas foram analisadas à luz de três categorias de participação: passiva, ativa e perceptiva. Na categoria de participação passiva o espectador observa, explora a obra; na participação ativa o espectador se torna parte da obra, explorando, intervindo, a fim de colaborar com a construção da mesma; na participação perceptiva, o espectador e o autor estabelecem uma relação recíproca, a partir da interatividade, que pode estar imposta através de interfaces computacionais. Resultados mostram que as experiências de aprendizagem em realidade aumentada desenvolvidas possibilitaram a imersão do sujeito/aluno no espaço híbrido por meio de práticas de participação ativa e perceptiva.
Animal Transformation in Early Modern English Witchcraft Pamphlets
Authors: Rutkowski Paweł
Published: October 2019

Animal metamorphosis was a traditional component of witchcraft beliefs during the European early modern witch-hunts, during which it was taken for granted that witches could and did turn into animals regularly in order to easier do evil. It must be noted, however, that the witch-turned-animal motif was much less common in England, where witches did possess the shape-shifting abilities but relatively rarely used them. A likely reason for the difference, explored in the present paper, was the specifically English belief that most witches were accompanied and served by familiar spirits, petty demons that customarily assumed the shape of animals. It seems that the ubiquity of such demonic shape-shifters effectively satisfied the demand for magical transformations in the English witchcraft lore.
Presenilin/γ-secretase-dependent EphA3 processing mediates axon elongation through non-muscle myosin IIA
Authors: Javier-Torrent Míriam , Marco Sergi , Rocandio Daniel , Pons-Vizcarra Maria , Janes Peter W , Lackmann Martin , Egea Joaquim , Saura Carlos A
Published: October 2019

EphA/ephrin signaling regulates axon growth and guidance of neurons, but whether this process occurs also independently of ephrins is unclear. We show that presenilin-1 (PS1)/γ-secretase is required for axon growth in the developing mouse brain. PS1/γ-secretase mediates axon growth by inhibiting RhoA signaling and cleaving EphA3 independently of ligand to generate an intracellular domain (ICD) fragment that reverses axon defects in PS1/γ-secretase- and EphA3-deficient hippocampal neurons. Proteomic analysis revealed that EphA3 ICD binds to non-muscle myosin IIA (NMIIA) and increases its phosphorylation (Ser1943), which promotes NMIIA filament disassembly and cytoskeleton rearrangement. PS1/γ-secretase-deficient neurons show decreased phosphorylated NMIIA and NMIIA/actin colocalization. Moreover, pharmacological NMII inhibition reverses axon retraction in PS-deficient neurons suggesting that NMIIA mediates PS/EphA3-dependent axon elongation. In conclusion, PS/γ-secretase-dependent EphA3 cleavage mediates axon growth by regulating filament assembly through RhoA signaling and NMIIA, suggesting opposite roles of EphA3 on inhibiting (ligand-dependent) and promoting (receptor processing) axon growth in developing neurons.
N-cadherin-regulated FGFR ubiquitination and degradation control mammalian neocortical projection neuron migration
Authors: Kon Elif , Calvo-Jiménez Elisa , Cossard Alexia , Na Youn , Cooper Jonathan A , Jossin Yves
Published: October 2019

The functions of FGF receptors (FGFRs) in early development of the cerebral cortex are well established. Their functions in the migration of neocortical projection neurons, however, are unclear. We have found that FGFRs regulate multipolar neuron orientation and the morphological change into bipolar cells necessary to enter the cortical plate. Mechanistically, our results suggest that FGFRs are activated by N-Cadherin. N-Cadherin cell-autonomously binds FGFRs and inhibits FGFR K27- and K29-linked polyubiquitination and lysosomal degradation. Accordingly, FGFRs accumulate and stimulate prolonged Erk1/2 phosphorylation. Neurons inhibited for Erk1/2 are stalled in the multipolar zone. Moreover, Reelin, a secreted protein regulating neuronal positioning, prevents FGFR degradation through N-Cadherin, causing Erk1/2 phosphorylation. These findings reveal novel functions for FGFRs in cortical projection neuron migration, suggest a physiological role for FGFR and N-Cadherin interaction in vivo and identify Reelin as an extracellular upstream regulator and Erk1/2 as downstream effectors of FGFRs during neuron migration.
Differential requirements for cyclase-associated protein (CAP) in actin-dependent processes of Toxoplasma gondii
Authors: Hunt Alex , Russell Matthew Robert Geoffrey , Wagener Jeanette , Kent Robyn , Carmeille Romain , Peddie Christopher J , Collinson Lucy , Heaslip Aoife , Ward Gary E , Treeck Moritz
Published: October 2019

Toxoplasma gondii contains a limited subset of actin binding proteins. Here we show that the putative actin regulator cyclase-associated protein (CAP) is present in two different isoforms and its deletion leads to significant defects in some but not all actin dependent processes. We observe defects in cell-cell communication, daughter cell orientation and the juxtanuclear accumulation of actin, but only modest defects in synchronicity of division and no defect in the replication of the apicoplast. 3D electron microscopy reveals that loss of CAP results in a defect in formation of a normal central residual body, but parasites remain connected within the vacuole. This dissociates synchronicity of division and parasite rosetting and reveals that establishment and maintenance of the residual body may be more complex than previously thought. These results highlight the different spatial requirements for F-actin regulation in Toxoplasma which appear to be achieved by partially overlapping functions of actin regulators.
Murder in the Consulate: The Grammar of Transitivity in the Headlines of News Reports about Jamal Khashoggi
Authors: Samir El-Falaky May
Published: October 2019

The present study explicates the nature of the lexicogrammatical choices made in journalistic discourse about the death of the Saudi journalist Jamal Khashoggi. The case is internationally represented in the mostly circulated newspapers. The online versions of the four newspapers Arab News (Kingdom of Saudi Arabia), Hürreyat Daily News (Turkey), New York Times (United States of America) and Tehran Times (Iran) are selected for the study. Proceeding within the framework of the transitivity system, the paper intends to expound how the four newspapers express the stances and viewpoints about the case. The analysis positions the newspapers writing technique within an ideological bifurcation of the legitimized US and the delegitimized THEM. The use of the transitivity system as an approach for analysis of the headlines unveils how journalists’ attitudes steer readers toward the opinions preferred by the national policies of their countries.
Losing Sight, Gaining Insight: Blindness and the Romantic Vision in Grimm’s “Rapunzel”
Authors: Wing Bo TSO Anna
Published: October 2019

In Brothers’ Grimm’s fairy tales, the motif of blindness occurs quite frequently, each time with a different symbolic meaning. In “Hansel and Gretel”, blindness is represented as a body deformity, an abject feature of the red-eyed, half-blind cannibalistic witch who lives in the candy house in the middle of the forest, while in “Cinderella”, blindness becomes more: a brutal punishment for wrongdoings, such as when: the wickedly unkind stepsisters’ eyes are pecked out by pigeons as they are on the way to the wedding of the Cinderella and her handsome prince. Yet, in “Rapunzel”, blindness is not meant to be an abject feature nor a direct punishment. Rather, it opens the door to the Romantic vision and spirit. Through studying the earlier versions of the Rapunzel story and the Grimm’s later version, this paper explores how blindness represents the limitations of logic and reason and, through embracing the beautiful power of the female sensibility, welcomes the rebirth of insight, faith and Romantic sentiments.
Structural Organisation of Research Article Titles: A Comparative Study of Titles of Business, Gynaecology and Law
Authors: Richard Appiah Kingsley , Ankomah Christopher , Yaw Osei Harrison , Hattoh-Ahiaduvor Timothy
Published: October 2019

Since titles are gateways to the heart of research articles (RAs), their organisational structure should be regarded very crucial in appealing to the potential reader. This study aimed to investigate how titles of RAs are presented in three disciplines (Gynaecology/Obstetrics, Business, and Law). After a thorough study of 574 titles, the study revealed that Business titles were averagely longer than those in the other two disciplines. In terms of title style, it was revealed that the Single Unit Title was extensively used in Gynaecology/Obstetrics and Law, while the Compound Unit Title dominated the Business titles. Syntactically, Noun Phrases extremely dominated the Single Unit Titles across the three domains. Detailed examination of the NP modifications showed that nominal titles which were both Pre and Post-modified were highly frequent in all the disciplines, which contrasts what is in the literature. The study also identified the Prepositional Phrase as the commonest structure used in post-modifying the nominal structures than using non-finite clauses in all the disciplines. Again, colon was the most predominant punctuation mark used in partitioning the Compound Unit Titles across the three disciplines, with Law recording the highest followed by Gynaecology/Obstetrics and Business. Lastly, the data exhibited high frequency of Domain-Specific words in the titles more than Research-Based words across the disciplines. This study provides useful information on the nature of effective RA titles to novice writers and advanced authors. It also informs the teaching of academic writing skills.
On the Gender Discrimination in English
Authors: Lan Tian , Jingxia Liu
Published: October 2019

Language, as a tool for people’s daily communication, has no gender bias itself. With the development of society, the language has changed correspondingly. Language serve as the mirror of society, inevitably reflecting people’s minds or ideology as well as the culture and social conditions of a society. While in English, as the mother tongue of many western countries, amounts of gender discrimination expressions are embodied. To some extent, the gender bias toward females serves as the embodiment that females are considerably insignificant and share a low social status. In this paper, the author will analyse the phenomenon of gender discrimination in English language, and find the reason behind it to make people realize the importance of eliminating this phenomenon. If people keep using sexism language unconsciously, it will become the hindrance of the social harmony.

This study is to understand the teaching materials, approaches and methods used in the plus curriculum in the teaching English as compulsory subject in the Madrasah Aliyah Darul Ulum Banda Aceh. An ethnography method was purposefully used where four participants were involved for an in-depth interview and classroom observation. The result revealed that the approaches were used namely scientific and communicative approach. The method becomes priority were lecture method, demonstration, discussion, simulation, grammar translation method, direct method, debate, and role play. Whereas the teaching material were sourced from the technical school guiding book, relevant technical books, magazines, visual-based teaching, audio-visual based and multimedia-based learning sources. Therefore, this is one of evidences that the using of teaching material, approaches and method under the plus curriculum can mediate the Madrasah Aliyah students’ English learning outcomes. This may put into account due to the specific educational and cultural issue and practices in those private Madrasah Aliyah. Moreover, it can be recommended to other schools in Banda Aceh to apply such an innovative and combination curriculum contents; local school and national curriculum instruction. A further ethnographic research is needed to investigate how teachers and principals prepare or determine teaching materials and learning model prior to the learning process conducted.

Obesity is demonstrated to be a risk factor in the development of cancers of various organs, such as colon, prostate, pancreas and so on. Leptine (LEP) is the most renowned of the adipokines. As a hormone, it mediates its effect through leptin receptor (LEPR), which is widely expressed in various tissues including colon mucosa. In this study, we have investigated the degree of expression of LEP and LEPR in colorectal cancer (CRC). We collected 44 surgically resected colon cancer tissues along with normal adjacent colon tissue (NACT) from a sample of CRC patients from the Malaysian population and looked for leptin and leptin receptors using immunohistochemistry (IHC). All the samples showed low presence of both LEP and LEPR in NACT, while both LEP and LEPR were present at high intensity in the cancerous tissues with 100% and 97.7% prevalence, respectively. Both were sparsed in the cytoplasm and were concentrated beneath the cell membrane. However, we did not find any significant correlation between their expression and pathological parameters like grade, tumor size, and lymph node involvement. Our study further emphasizes the possible causal role of LEP and LEPR with CRC, and also the prospect of using LEPR as a possible therapeutic target.

Hydrocolloids isolated from the flour of peels of selected root and tuber crops were purified and their physicochemical properties were determined using standard procedures. The experimental material used was the peels of three species of Dioscorea: alata (water yam), dumentorum (trifoliate yam), rotundata (white yam) and bulbifera (aerial yam); Colocasia esculenta (cocoyam); white and yellow flesh of Ipomoea batatas (sweet potato). The fresh peels were dried under three drying method (oven, sun and air-dried). Proximate composition gave 4.4 to 10.7% for moisture content, 0.40 to 6.10% for ash content, 0.32 to 4.13% for crude fibre and in carbohydrates it ranges from 81.3 to 93.7%. There were no fat and protein in the experimental samples. Oven-dried alata peel flour gave the highest swelling index value 1.44% while, air-dried had the highest value of (4.00%) ranking the highest in foaming capacities. The highest in water and oil absorption capacities were sun-dried (2.05) dumentorum peel and rotundata peel air-dried (2.21). In emulsifying capacity and freezing-thawing stability, the highest results were observed in colocasia peel oven-dried (54.3%) and white flesh Ipomoea batatas peel sun-dried (74.3%). Yellow flesh Ipomoea batatas (0.31 g/ml) gave the lowest in bulk density. Gelation temperature ranges from 70 to 83ºC with pH of 6.6 to 7.6.
Modelling of Instructors Publication Factors in Ethiopia Public Universities: Advanced Count Regression Models
Authors: Abebe Alebachew
Published: October 2019

Instructors’ publication (IP) is one of the major activity in higher education institutes. Currently, IP faced problem both high prevalence and severity in Ethiopia public universities. Even if the problem is common to both developed and developing countries, about 352 (73.9 %) of the instructors employed by public universities in Ethiopia have been affected by a lack of scholarly publications. Since the outcomes from IP factors are mostly discrete variable; they are often modelled using advanced count regression models. The purpose of this study was to model the appropriate count regression model that efficiently fit the IP data and further to identify the key risk factors contributing significantly to IP in public Universities in Ethiopia. The data were collected between November 2015 through November 2016 from selected thirteen (13) public universities in Ethiopia through both questionnaires and interview. The cross-sectional study design was employed using IP data. A simple random sampling technique was applied to the population of Ethiopia public universities to obtain a sample of 13 universities or 476 individual instructors were selected. The average age of the 476 participants was found to be 30 years with 31(6.5%) being females and 445(93.5%) being males. The count outcomes obtained were modelled using count regression models which included Zero-Inflated Negative Binomial (ZINB), Zero-Inflated Poisson (ZIP) and Poisson Hurdle regression models. To compare the performance and the efficiency of the listed count regression models concerning the IP data, the various model selection methods such as the Vuong Statistic (V) and Akaike’s Information Criterion (AIC) were used. The ZINB count regression model concerning the values of the Vuong Statistic and AIC was selected as the most appropriate and efficient count regression model for modelling IP data. Based on the ZINB model the variables age, experience, average work-load, association member and motivation to work were statistically significant risk factors contributing to IP in Ethiopia public universities.

Study Design: This was a hospital-based cross-sectional study.

Place and Duration of Study: This study was carried out at the Dialysis clinic of the University of Port Harcourt Teaching Hospital, Rivers State, Nigeria from February 2013 to February 2014.

Methodology: The Sample size was estimated to be 85 adult patients and cconsecutive adult patients with chronic renal failure who are having haemodialysis were enrolled into the study. The patients who met the inclusion criteria were randomly booked at the Dialysis Clinic and had no prior knowledge of the study; hence there was no bias in case selection. Ethical approval was obtained from the institutions ethical committee. Each participant had a comprehensive ocular examination including fundus photography. Subjects needing further evaluation and treatment were referred to the Eye Clinic of the Ophthalmology Department of the University of Port Harcourt Teaching Hospital, Port Harcourt.

Results: A total of 170 eyes of 85 persons were examined in this study (100% coverage). A total of 30 (35.4%) females and 55 (64.6%) males were examined giving a male to female ratio of 1.8:1.

Approximately half of the study subjects (54.1%) had no previous eye problem prior to developing chronic renal failure while about a quarter (n= 20, 23.5%) had refractive error and difficulty in reading near prints .After diagnosis of chronic kidney disease however a total of 40 (47%) of study subjects had visual impairment while 2(2.4%) were blind and 43(50.6%) of the study population however had normal vision.

Conclusion: Chronic Kidney disease is an important cause of ocular morbidity in our environment with majority of those affected being males in the third to fifth decades of life. Posterior segment disorders were the commonest disorders seen.

As two‐dimensional (2D) layered materials attract more attention owing to their unique optical, electrical, and thermal properties, there are persistent efforts to grow high‐quality 2D layered materials for fundamental research and device applications. While large‐area 2D layered materials with high crystal quality can be obtained through chemical vapor transport, the strong binding between 2D layered materials and substrates poses a significant challenge for attempts to reveal their intrinsic properties and to use these 2D building blocks for constructing advanced heterostructured devices. Therefore, it would be ideal to grow high‐quality 2D materials with minimized contact and binding with substrate. Through both calculation and experiment, it is demonstrated that by introducing a seed layer at the nucleation stage, the crystallographic disregistry and the corresponding adhesion energy between 2D materials and substrate can be altered, resulting in a change of crystal surface in contact with the substrate, and therefore vertical growth of 2D materials on substrates. As an example, it is demonstrated that with Bi2O3 serving as a seed layer, vertical growth of 2D plates of Bi2O2Se on mica substrates can be realized. These vertically grown 2D nanoplates of Bi2O2Se can be conveniently transferred with their thermal properties investigated for the first time.
