“Na minha época não tinha escapatória”: teleologias, temporalidades e heteronormatividade
Authors: Henning Carlos Eduardo
Published: February 2016

Resumo Este artigo se volta a analisar alguns elementos recorrentes que se fizeram presentes nos relatos de campo ao longo de minha etnografia para o doutorado em Antropologia Social na Unicamp. Meus contatos de campo foram homens entre os 45 e os 70 anos de idade que mantinham práticas sexuais homoeróticas e/ou que se identificavam como homossexuais. Os relatos reincidentes enfocavam as lidas com pressões sociais em prol da realização de determinados marcos biográficos tidos como heterossexuais e convencionados como imprescindíveis para se alcançar a felicidade e a plenitude no ínterim do curso da vida. Em um diálogo com uma vertente contemporânea dos estudos queer estadunidenses, a qual costuma ser chamada de tempo queer e temporalidades queer, – e ao mesmo tempo apresentando uma revisão desses debates – problematizo criticamente o modo como as transições entre os distintos períodos da vida são concebidas, em especial como são imaginadas e convencionadas. Por fim, a partir dessas análises de campo e diálogos teóricos, proponho a noção de teleologias heteronormativas de modo a desenvolver o debate acerca das bases prescritivas heterossexuais que tendem a fundamentar persuasivamente o modo como o curso da vida – em suas transições e em sua totalidade – é compreendido e negociado no contemporâneo.

Published: February 2016

ABSTRACT The development of efficient machines for the mechanical harvesting of coffee plants requires the use of appropriate vibrational parameters. Thus, in order to detach less unripe fruits and decrease reharvesting, branch breakage and defoliation, it is important to choose the appropriate frequency, amplitude and vibration time. This study aimed at analyzing the detachment efficiency of fruits from coffee plants according to vibrational parameters and ripening stage. Fruit bunches were sampled at the green and mature stages and subjected to vibration, using a system composed by a signal generator, an amplifier and an electromagnetic vibrating machine. Tests combined different frequencies (16.4 Hz, 20.3 Hz, 24 Hz, 25.6 Hz, 30.0 Hz and 33.0 Hz), amplitudes (5.0 mm, 7.0 mm and 9.0 mm) and vibration times (10.0 s and 20.0 s). The vibration times did not affect the detachment efficiency. There was a trend for higher detachment efficiency in mature fruits than in green fruits. The detachment efficiency increased with increasing vibration frequency and amplitude.

Published: February 2016

RESUMO O cultivo de algodoeiro adensado em segunda safra, em ambiente não irrigado, após soja ou feijão, tem aumentado no Cerrado do Centro-Oeste brasileiro. Com essa mudança de época de semeadura, as plantas de algodão estão mais expostas a condições climáticas adversas. Objetivou-se avaliar o efeito de cultivares, densidades de plantas e épocas de semeadura sobre a produção de algodão. Os experimentos foram realizados em três anos consecutivos. Em cada ano, os tratamentos foram constituídos por duas épocas de semeadura (segunda quinzena de janeiro e primeira quinzena de fevereiro), cultivares (ciclo precoce e médio) e densidades de plantas (8,9-33,3 plantas m-2). O algodão foi semeado em segunda safra, após a colheita de soja precoce. Em cada época de semeadura, os experimentos foram instalados no delineamento de blocos ao acaso, em parcelas subdivididas, com o fator cultivar disposto na parcela e a densidade na subparcela. A produtividade do algodoeiro em segunda safra foi pouco influenciada pelas densidades de plantas e cultivares. A semeadura tardia do algodoeiro reduziu a altura de plantas, número de capulhos por área e produtividade de fibra. Com o atraso na data de semeadura, a produtividade de fibra diminuiu aproximadamente 25 %, 17 % e 41 %, respectivamente em 2009, 2010 e 2011. O fator mais determinante para o cultivo do algodoeiro em segunda safra é a época de semeadura.

Published: February 2016

RESUMO A recuperação de solos com elevada salinidade e alcalinidade requer a utilização de produtos que promovam a redução do pH e diminuam os teores de Na trocável, para melhorar a sua fertilidade. Objetivou-se avaliar o efeito do sulfato de cálcio e do enxofre elementar sobre os atributos químicos de um solo com altos teores de sais solúveis e Na trocável. Dois experimentos foram conduzidos em casa-de-vegetação, utilizando-se amostras de um Neossolo Flúvico sódico sálico de textura franco-arenosa. No primeiro experimento, foram testados quatro tratamentos referentes à correção do solo (sem corretivo, sem corretivo e sem lavagem, corrigido com sulfato de cálcio e corrigido com enxofre elementar). No segundo experimento, os tratamentos compreenderam cinco doses de enxofre elementar (0 kg ha-1, 400 kg ha-1, 800 kg ha-1, 1.200 kg ha-1 e 1.600 kg ha-1). O enxofre elementar e o sulfato de cálcio influenciaram positivamente os atributos químicos do solo, proporcionando melhor fertilidade. O enxofre elementar, além de melhorar os atributos químicos desse solo, é mais eficiente que o sulfato de cálcio na diminuição de sua alcalinidade, contudo, o uso desse produto requer a aplicação de fonte adicional de cálcio ao solo. Devido ao seu baixo teor de argila, a simples lavagem contribui para diminuir a salinidade e sodicidade do solo.
Adjustment of water-crop production models for ratoon sugarcane
Authors: Souza Jorge Luiz Moretti de , Gerstemberger Emerson , Gurski Bruno César , Oliveira Ricardo Augusto de
Published: February 2016

ABSTRACT Production models need to be tested at different locations to be used as an agricultural planning tool. Hydric relations and performances of water-crop production models were used to estimate ratoon sugarcane yield along nine production cycles, in Paranavaí, Paraná State, Brazil. The crop reference and real evapotranspiration, soil water storage, water deficit and surplus were evaluated. The "Stewart" and "Jensen" models showed the best performance to estimate ratoon sugarcane yield. Water availability in the first development phase of ratoon sugarcane has the greatest influence on yield.
Efeito da temperatura de armazenamento na conservação pós-colheita de amora-preta
Authors: Palharini Maria Cecília de Arruda , Fischer Ivan Herman , Vegian Mariana Raquel da Cruz , Fileti Mirian de Souza , Montes Sonia Maria Nalesso Marangoni
Published: February 2016

RESUMO Os frutos da amoreira-preta apresentam vida útil relativamente curta, devido à sua estrutura frágil, alto metabolismo e ocorrência de doenças, exigindo, portanto, cuidados em seu armazenamento. Objetivou-se avaliar o efeito de diferentes temperaturas na conservação de amora-preta (cv. Brazos), caracterizando os atributos físico-químicos e quantificando os patógenos causadores de podridões. Utilizou se delineamento experimental inteiramente casualizado, em esquema fatorial (temperaturas x pomares), com três repetições de 10 frutos por tratamento. As temperaturas de 2 ºC e 5 ºC foram eficientes em retardar a mudança de coloração e a degradação dos ácidos orgânicos. Observou-se aumento significativo na incidência de podridões com o aumento da temperatura de armazenamento. Incidências inferiores a 7 % foram observadas ao final do armazenamento a 2 ºC e 5 ºC, mas superaram 20 % em temperaturas a partir de 15 ºC. Os principais pátogenos detectados foram Cladosporium spp. e Colletotrichum spp. A refrigeração a 2 ºC e 5 ºC constitui eficiente alternativa para manter a qualidade dos frutos de amora-preta por até nove dias, por retardar o amadurecimento e o desenvolvimento de podridões.
Silício na nutrição mineral e acúmulo de alumínio em plantas de arroz de terras altas
Authors: Freitas Lucas Barbosa de , Fernandes Dirceu Maximino , Maia Suelen Cristina Mendonça
Published: February 2016

RESUMO O silício é capaz de proteger as plantas contra vários estresses bióticos e abióticos, entre eles o estresse por alumínio. No entanto, a interação entre silício e alumínio ainda é pouco conhecida, sendo que há diversas hipóteses para justificar o papel do silício na amenização do estresse causado por alumínio. Objetivou-se avaliar o efeito da aplicação de silício nos teores e acúmulos de macro e micronutrientes, alumínio e silício na parte aérea de plantas de arroz de terras altas cultivadas sob estresse por alumínio, bem como as características químicas do solo após a colheita. O delineamento experimental utilizado foi o de blocos casualizados, disposto em modelo fatorial 2 x 5, com quatro repetições. Os tratamentos consistiram de duas cultivares de arroz de terras altas (BRS Talento - não tolerante ao alumínio; Guarani - tolerante ao alumínio) e cinco doses de silício (0 mg dm-3, 30 mg dm-3, 60 mg dm-3, 90 mg dm-3 e 120 mg dm-3). O silício aplicado aumenta o teor de silício na planta e no solo e diminui o teor de alumínio na parte aérea, porém, não incrementa a absorção de macro e micronutrientes e não altera o teor de alumínio e pH do solo.
The Bletia catenulata ornamental orchid is self-compatible but pollinator-dependent for reproduction
Authors: Paiva Neto Vespasiano Borges de , Correa Ana Paula Mezoni , Barros Fábio de , Padilha Daly Roxana Castro , Borges Monica Cristina Rezende Zuffo
Published: February 2016

ABSTRACT Bletia catenulata is a native Brazilian orchid whose populations have suffered from predatory collection. Aiming at elucidating aspects of its reproductive biology and the relation with seed germination, pollination tests were carried out in flowers of plants cultivated in a greenhouse. Manual cross and self-pollination resulted in high percentage of fructification (76.7-86.7 %), being only 26.7 % for natural pollination, in which the absence of pollinators, due to flower isolation, resulted in absence of fruits. In vitro seed germination for all fruits from the different pollination processes was low, being 8.6 % the highest percentage for protocorms. Thus, B. catenulata is selfcompatible, resulting in viable seeds, but pollinator-dependent for sexual reproduction.

Authors: Garcia Rosilei Aparecida , Marinonio Gabriel Bittencourt
Published: February 2016

RESUMO O objetivo deste estudo foi avaliar o efeito da densidade e do teor de extrativos na variação da cor da madeira de teca (Tectona grandis L. f.) proveniente de plantios de diferentes espaçamentos. As análises colorimétricas foram realizadas nas faces radial e tangencial das madeiras de cerne e alburno com o espectrofotômetro CM 2600d no espaço de cor L*a*b*. A densidade e o teor de extrativos foram determinados segundo as normas ASTM D2395 e ASTM D1105. A madeira do maior espaçamento de plantio apresentou maior densidade e maior teor de extrativos. Na seção radial, as madeiras de cerne de maior densidade apresentaram mais pigmento amarelo, enquanto que na seção tangencial elas são mais escuras e apresentam menos pigmento amarelo. As madeiras de alburno de maior densidade são mais escuras e apresentam mais pigmento vermelho em ambas as seções. As madeiras mais escuras e com mais pigmento vermelho apresentaram um maior teor de extrativos.
Dynamiques Créatives d'un Patrimoine Immatériel: la transmission orale du théâtre dansé Bharata-Nâtyam à Mysore (Inde)
Authors: Légeret Katia
Published: February 2016

Résumé: Les chercheurs qui s'intéressent aux patrimoines des théâtres dansés en Inde rencontrent un obstacle majeur, celui de leur oralité, car les archives écrites et audiovisuelles sont rarissimes. Ils doivent suivre une formation professionnelle pour avoir accès aux matériaux de recherche et pouvoir les interpréter. L'étude de cas du style Bharata-Nâtyam de Mysore, implique cette observation participante du chercheur-artiste et démontre que la vitalité de cet héritage tient à la créativité de chaque transmission locale et individuelle - selon son contexte social, esthétique, religieux et politique - et non aux œuvres dites achevées et reconnues par un public national ou international.
About Research in the Arts: a lover's discourse
Authors: Royo Victoria Pérez
Published: February 2016

Abstract: This paper is the result of an exercise of experimental re-writing and analogical thinking which had as an aim to open a new perspective on research in the arts. In terms of method, the different figures of love in Barthes' A Lover's Discourse are forced to talk about the relationship of researcher and object of study. This analogy allows us to find quality parameters based on a scale of values different to the hegemonic ones in the academy (productivity, competitiveness, innovation). These new parameters might constitute a solid ontological basis to build a new politics of artistic research in the academy that allow a radical reconsideration of processes of artistic research.
Postdramatic Theatre and Postdramatic Performance
Authors: Carlson Marvin
Published: February 2016

Abstract: Beginning with the concept of a postdramatic theatre as articulated by the German theorist Hans-Thies Lehmann, this essay considers the recent work of several major international directors - Ivo van Hove, Punchdrunk, Signa and others - as examples of postdramatic performance. It argues that what they have in common is a challenge to the traditional concept of mimesis and of the theatre world as a fictional construct distinctly separated from everyday life and its surroundings.
Reconsidering Acting: a few improvised and provisory thoughts on acting today
Authors: Pavis Patrice
Published: February 2016

Abstract: This paper summarizes my thoughts during the presentation of the conference Acting reconsidered. The study of the actor in contemporary performances should be reevaluated in the light of the experiments of the last fifty years, particularly performance art, post-dramatic theatre, participative theatre and many political theatre. The new tasks and conceptions of the actor are introduced. Stanislavki's notion of psychological realism is questioned. The suggestion of de-dramatizing, delocalizing, de-training the actor might help the actor to orient oneself in the world.
Degustação de Palavras: para uma experiência sensorial de linguagem e pensamento no trabalho do ator
Authors: Holesgrove Thomas William
Published: February 2016

Resumo: A partir da concepção metafórica a palavra é alimento, propõe-se uma série de quatro exercícios, como uma degustação de palavras, para a investigação sensorial da voz, da linguagem e do pensamento no trabalho do ator. Por meio de uma exploração da proximidade entre o falar e o comer, os exercícios buscam estimular a percepção sensível do modo como a palavra reverbera pelo corpo inteiro. A proposta visa a diminuir o controle mecânico de processos orgânicos e a manipulação direta da voz de acordo com noções estéticas preconcebidas. Ao mesmo tempo, se propõe a aprofundar a experiência físico-intelectual-emocional-sociocultural do texto no teatro.

Authors: Huapaya Cesar
Published: February 2016

Resumo: O pensar como montagem e imagem tornou-se um método revelador nos processos de estudos práticos e teóricos do artista e dos pesquisadores nos séculos XX e XXI. Este artigo procura articular três formas de pensar por montagem: nas obras de Bertolt Brecht, Sergei Eisenstein e Georges Didi-Huberman. O filósofo e historiador da arte Georges Didi-Huberman reinaugura o debate e o exercício de pensar a antropologia da imagem e a montagem como metalinguagem e forma de conhecimento.
No Marulhar das Glossolalias em Artaud
Authors: Almeida Gil Roberto , Lignelli César
Published: February 2016

Resumo: A partir da obra de Artaud, evidencia-se um ideário que sugere princípios para uma vocalidade no contexto da performance. Essa vocalidade é baseada em uma noção de glossolalia como conceito vinculado às práticas enunciativas, sobretudo como potência para desarrazoar estratos vocais. Assim, a glossolalia pode agregar valores sonoro-poéticos que desestabilizam aspectos da produção e percepção de sentidos relacionados à voz. Busca-se aqui uma discussão sobre possíveis fronteiras da produção vocal. Serão apropriados conceitos da obra de Deleuze e Guattari, assim como reflexões de Certeau e Pozzo. Os objetivos do artigo importam em suscitar e valorizar aspectos de uma vocalidade glossolálica, visando ampliar as possibilidades do performer contemporâneo, problematizando o contexto de suas práticas vocais.
TECNOLOGIAS MÓVEIS NA INCLUSÃO ESCOLAR E DIGITAL DE ESTUDANTES COM TRANSTORNOS DE ESPECTRO AUTISTA
Authors: SANTAROSA Lucila Maria Costi , CONFORTO Débora
Published: February 2016

RESUMO Com foco nas políticas públicas inclusivas, a relação entre estudantes com Transtorno de Espectro Autista e dispositivos móveis foi problematizada para discutir os limites e as possibilidades da configuração tecnológica 1:1 em apoiar processos de inclusão escolar e digital na rede pública brasileira de ensino. Metodologicamente, caracteriza-se como uma pesquisa qualitativa de enfoque exploratório e explicativo, epistemologicamente apoiada na teoria sócio-histórica e conduzida por dois grandes questionamentos: (i) Os dispositivos móveis apresentam interface acessível a sujeitos com Transtornos de Espectro Autista? (ii) Que movimentos foram desencadeados pela mediação dos dispositivos móveis para potencializar a inclusão sociodigital de sujeitos com Transtornos de Espectro Autista? A partir dos dados coletados foi possível analisar as fragilidades e as potencialidades da interação de três sujeitos de pesquisas, estudantes dos anos iniciais da Educação Básica em processo de alfabetização, pela interface da tecnologia móvel. O comportamento refratário dos sujeitos de pesquisa em relação ao laptop educacional pode ser justificado pelos problemas de acessibilidade tecnológica associada ao dispositivo móvel, muitos deles potencializados pelas especificidades do Transtorno de Espectro Autista: interface pouco amigável, de difícil compreensão pelo grau de abstração e pela complexidade do sistema operacional, com suas múltiplas escolhas e configurações. Na interação com o tablet foi possível constatar um manuseio amigável e intuitivo, pois a manipulação com o objeto ocorre de forma direta e natural, com o toque do dedo. A arquitetura dessa tecnologia permite seu uso em diferentes lugares e posições, uma resposta positiva à hiperatividade e para qualificar estratégias de mediação pedagógica.
ESTRATÉGIAS PEDAGÓGICAS EMPREGADAS POR PROFESSORES DE EDUCAÇÃO ESPECIAL AOS SEUS ALUNOS COM DEFICIÊNCIA INTELECTUAL SEVERA: UM ESTUDO DESCRITIVO DA PRÁTICA DOCENTE
Authors: CARAMORI Patricia Moralis , DALL'ACQUA Maria Júlia Canazza
Published: February 2016

RESUMO Esta pesquisa aborda a temática da educação de indivíduos com deficiência intelectual severa a partir das estratégias pedagógicas utilizadas por professoras de Educação Especial. Justifica-se por abordar o processo educacional de uma população pouco investigada, além de unir dois eixos de discussão de forma inovadora: a Teoria da Modificabilidade Cognitiva Estrutural (MCE) de Reuven Feuerstein e a educação de alunos severamente prejudicados. Segundo essa Teoria, o professor atua como mediador, interpondo-se entre os estímulos do ambiente e o aluno. Seu objetivo pauta-se na descrição e análise da implementação do processo educacional de alunos com deficiência intelectual severa, enfocando as estratégias pedagógicas de professoras de Educação Especial na cidade de Araraquara. Os procedimentos iniciais indicam o estabelecimento dos perfis das professoras, seu mapeamento e localização. Definidos os participantes, a coleta dos dados se deu por meio de três instrumentos: entrevista semiestruturada realizada com as professoras e observação, registrada em protocolo e em diário de campo. Os dados foram analisados qualitativamente a fim de permitir a extração de detalhes do cotidiano observado. Os resultados apresentam uma descrição do trabalho das quatro professoras participantes, evidenciando suas opiniões sobre suas práticas, além de arrolar as estratégias pedagógicas utilizadas. Oferece-se como conclusão a identificação de estratégias pedagógicas que se relacionam com os critérios que regem a mediação. Isso mostra que é possível associar as idéias de Feuerstein às práticas pedagógicas voltadas aos alunos com deficiência intelectual severa, já que determinados procedimentos empregados demonstram trazer em seu cerne alguns preceitos essenciais à mediação.

Published: February 2016

RESUMO A Comunicação Suplementar e Alternativa (CSA) é uma área da tecnologia assistiva que busca facilitar a participação das pessoas nos vários contextos comunicativos. Há uma variedade de estratégias em CSA e uma delas é o Sistema de Comunicação por Troca de Figuras (PECS) que propõe desenvolver as habilidades de comunicação em pessoas com necessidades complexas de comunicação. Associado à aplicação do PECS, algumas pesquisas tem demonstrado os benefícios do uso do Video Modeling (VM) que consiste em uma técnica de ensino voltada às habilidades acadêmicas, sociais, de comunicação e vida diária para indivíduos das mais variadas deficiências. Este estudo teve por objetivo investigar os efeitos do PECS associado ao VM acerca do desenvolvimento das habilidades de comunicação de uma criança com síndrome de Down com necessidades complexas de comunicação. Neste sentido, para investigar os efeitos do PECS associado ao VM um delineamento AB foi empregado, sendo o PECS associado ao VM a variável independente, enquanto as habilidades de comunicação constituíram-se na variável dependente. Os dados foram analisados considerando alguns aspectos como o desempenho da participante, monitoramento do vocabulário, nível de independência nas etapas de linha de base, intervenção e manutenção. Os resultados indicaram que a participante aumentou as iniciações comunicativas, o vocabulário, além de demonstrar independência em utilizar o sistema PECS para se comunicar com diferentes pessoas. Dessa forma, o presente estudo mostrou uma possibilidade de intervenção que favoreceu o desenvolvimento das habilidades de comunicação da participante com síndrome de Down.
ESTUDOS NACIONAIS SOBRE O ENSINO PARA CEGOS: UMA REVISÃO BIBLIOGRÁFICA
Authors: FIGUEIREDO Rosana Mendes Éleres de , KATO Olívia Misae
Published: February 2016

RESUMO O presente artigo tem como objetivo apresentar uma revisão bibliográfica dos estudos nacionais acerca do ensino curricular para cegos. Foi realizada uma busca sistemática em três bases de dados: Google Acadêmico, Scielo e Lilacs, de estudos publicados no período de 2004 a 2014, que tivessem em seu título um dos seguintes descritores: alunos cegos; alunos deficientes visuais; crianças cegas; crianças deficientes visuais. Foram localizados 188 estudos e 56 selecionados dentro dos critérios estabelecidos. Fez-se a leitura integral desses e definiram-se cinco categorias de análise: tipo de estudo; participantes; tipo de abordagem; tipo de discussão e matrizes curriculares. Para cada categoria, foram estabelecidas subcategorias. Ao total 26 subcategorias foram descritas. Os resultados indicam que o Google Acadêmico é a base de dados com maior número de títulos encontrados (188/156); a Scielo apresenta melhor eficiência na relação encontrado x selecionado (12/10). Nas subcategorias de análise, as maiores frequências são identificadas nos estudos empíricos (22); junto a crianças (19); de análises qualitativas (21); na matriz curricular de Educação Física (sete) e na subcategoria relacionamento social (16). Contudo, os estudos são convergentes em apontar que as principais dificuldades no ensino às pessoas cegas se referem a deficiências na formação de professores, onde, normalmente, não são discutidos métodos de ensino e produção de material para trabalhar com essa população específica. Em conclusão, além de realizar um mapeamento dos estudos que têm sido conduzidos junto a alunos cegos nos últimos dez anos, este artigo aponta para lacunas na literatura e direciona futuras investigações na área.
Short communication: (What) To teach or not to teach – that is the question
Authors: Santamarina Juan Carlos
Published: February 2016

There has been an explosion of knowledge in geotechnical engineering, yet the art and science paradigm remains deeply rooted in the field. Geotechnical engineering students will face today’s prevailing difficulties as well as new and demanding geotechnical challenges such as those associated with energy and the environment. Confronting these situations and needs requires a sound and resourceful foundation. Therefore, geotechnical engineering teachers must review their educational programmes (a) to reconsider the role of empiricism, (b) to prune incorrect concepts and biases (e.g., enduring misnomers, incorrect explanations, superseded graphical approaches, unsound tricks and fragile correlations, and education based on extremes (dry–saturated, clay–sand, drained–undrained)), and (c) to promote a careful understanding of fundamentals (e.g., the particulate nature of soils and fractured rocks, formation history, the essential relevance of effective stress, thermo-hydro-chemo-mechanical coupled processes, repetitive loads and ubiquitous localisations). Finally, they must continue reflecting on the role of the engineer in society, within an ever-changing world as the driver for innovation.

IgA nephropathy (IgAN), characterized by mesangial IgA1 deposits, is a leading cause of renal failure worldwide. IgAN pathogenesis involves circulating hypogalactosylated IgA1 complexed with soluble IgA Fc receptor I (sCD89) and/or anti–hypogalactosylated-IgA1 autoantibodies, but no specific treatment is available for IgAN. The absence of IgA1 and CD89 homologs in the mouse has precluded in vivo proof-of-concept studies of specific therapies targeting IgA1. However, the α1KI‑CD89Tg mouse model of IgAN, which expresses human IgA1 and human CD89, allows in vivo testing of recombinant IgA1 protease (IgA1‑P), a bacterial protein that selectively cleaves human IgA1. Mice injected with IgA1‑P (1–10 mg/kg) had Fc fragments of IgA1 in both serum and urine, associated with a decrease in IgA1–sCD89 complexes. Levels of mesangial IgA1 deposits and the binding partners of these deposits (sCD89, transferrin receptor, and transglutaminase 2) decreased markedly 1 week after treatment, as did the levels of C3 deposition, CD11b+ infiltrating cells, and fibronectin. Antiprotease antibodies did not significantly alter IgA1‑P activity. Moreover, hematuria consistently decreased after treatment. In conclusion, IgA1‑P strongly diminishes human IgA1 mesangial deposits and reduces inflammation, fibrosis, and hematuria in a mouse IgAN model, and therefore may be a plausible treatment for patients with IgAN.

This qualitative study aimed to present baseline information about the academic and social experiences of the foreign students at the University of the Immaculate Conception (UIC). The researchers conducted a focus group discussion involving 15 of them who are currently enrolled in various programs of the university. Through an in-depth interview, it was found that most of the foreign students have known UIC via a recommendation of a friend, or the internet. Findings revealed that the existence of the foreign students in UIC is characterized both by pleasant and unpleasant experiences. The positive feedback about the UIC educational system opens a possibility for more influx of foreign students while the unpleasant experiences pose dramatic amendments in established policies of the university.
Low-Cost Venturi Meter: Understanding Bernoulli’s Equation Through A Demonstration
Authors: Limjuco Renan P. , Glover Fr. Francisco G. , Mendez Isagani M.
Published: February 2016

This study intended to concretize Bernoulli’s principle through a low-cost Venturi meter designed and constructed by the researchers. Specifically, this paper aimed to improvise a device that can measure flow speeds of water both in the wide and narrow portions of a horizontal piping system for which the pressure difference is provided by a differential height revealed in the attached manometer. A mechanism which regulates volume flow rate of liquid was attached to Venturi meter to generate several trials required to establish accuracy of setup in demonstrating Bernoulli’s principle. This investigation about improvisation of apparatus required experimental development method especially in assembling various components which included PVC pipe, aluminum pipe, manometer, DC pump, variable flow controller, and a plastic container as water reservoir. The final model of the apparatus evolved from a series of functionality test sessions with experts and consultants. To determine the accuracy of the instrument, nine trials--that is three each for the three adjusted flow rates, were performed. Findings revealed that the improvised Venturi meter can concretize Bernoulli’s principle. Its accuracy in flow speed determination was high since average percentage of error for minor turbulent flow was 12.52 per cent while that for laminar was 3.86 per cent.
The Distribution and Relative Abundance of Medium-sized Arboreal Mammals at Mt. Mahuson, Mount Apo Key Biodiversity Area
Authors: Aya-ay Adorico M.
Published: February 2016

Arboreal mammals comprise the bulk of the diet of the Philippine Eagle Pithecophaga jefferyi, a globally threatened bird species that is found only in the Philippines. Field surveys were conducted in Mt. Mahuson in Arakan Valley, North Cotabato Province from October 2009 to March 2011. The team concentrated on searching for Mindanao Flying Lemur Cynocephalus volans, Mindanao Flying Squirrel Petinomys crinitus, Palm Civet Paradoxurus hermaphroditus, and Long-tailed Macaque Macaca fascicularis as these are the reported common prey items of the Philippine Eagle. The team conducted mammal surveys for a total of 48.38 observation hours in seven line transects with a total length of 14 km if connected end to end. The team was also able to gather data from opportunistic sampling and dialogues with parabiologists. Results of the transect surveys indicate that among these species, the Long- tailed Macaques are the ones abundant particularly in the remaining forests at lower altitude (below 1300 masl), followed by the Mindanao Flying Lemur and Palm Civet. The Philippine Tree Squirrel scored only “frequent” whereas both the Mindanao Flying Squirrel and Pygmy Squirrel were found rare in the study area. This study tells us that lemurs are not the primary prey items of the nesting pair in Mt. Mahuson, a finding contrary to what is known that a large bulk of the prey items of the Philippine Eagle population in Mindanao consists of flying lemurs. This hypothesis could be tested with further assessment of the prey population and foraging behavior of the eagle pair in the mountain.

Authors: Moso Raymundo S. , Capricho Neil C.
Published: February 2016

This study is an experimental development which aimed to improvise a millisecond timer for motion experiments in General Physics. Specifically, it intended to design an opto-isolator circuitry with more sensitive response, which can interface with the stopwatches in the laboratory stockroom. This investigation also sought to describe the features of the improvised millisecond timer and to assess its comparability with the multifunctional millisecond timer in terms of time readings in each of the following experiments, namely: Slow Ball, Free Fall, Uniform Acceleration on an Inclined Plane, and Pendulum. Statistical analyses employed means, standard deviations and t-test to measure the significance of the difference in time readings. Results revealed that the improvised timer was as efficient as the multifunctional timer with respect to the experiments included in the study since the p-values were all greater than 0.05, implying that for each laboratory activity, there is no significant difference in the time readings from the two devices.

Published: February 2016

This study aimed to assess and compare the knowledge, skills and attitude of the staff nurses in selected public and private tertiary hospitals in Davao City. Through a descriptive comparative approach, the researcher made use of a survey utilizing validated questionnaires that were administered to 62 respondents. Results revealed that both government and private hospital nurses possessed low level of knowledge on of insulin and insulin administration. However, the respondents demonstrated a high level with respect to attitude. No significant relationship was established between the demographic profile of the government hospital nurses and their knowledge, skills and attitudes in insulin and insulin administration except in attitude within the ward or department they are assigned to. No significant relationship was established between the demographic profile of the private hospital nurses and their knowledge, skills and attitudes in insulin and insulin administration except in skills with respect to the number of seminars attended. There was no significant difference between the government and private hospital nurses in terms of knowledge on insulin administration.

Authors: Magdaluyo Fe Frauline C.
Published: February 2016

The increased complexity and importance of today’s nursing for human life have been confronted by the theoretical and clinical learning behaviors of nursing students during the past decade. Thus, behavior of nursing students in the clinical area has been accepted as an important factor to influence the quality and competency of nursing care, knowledge, and skills. This study aimed to determine the extent of behavior of the nursing students in the clinical area and the extent of nursing roles performed by them. It used a self-administered questionnaire which was validated by three experts in the field and subjected to Cronbach’s Alpha reliability test. The researcher employed the non-probability design with convenience sampling in the selection of nursing students and clinical instructors as respondents of the study. Findings indicated that all parameters of nursing roles were rated consistently “good” by both nursing students and clinical instructors. Further, results revealed that work performance of the nursing students of the nursing role is significantly associated with the behavior of the nursing students in the clinical area.
Discourse Analysis of Persuasive Language in Philippine Print Advertising
Authors: Fernandez Edroslyn J.
Published: February 2016

This qualitative study employed discourse analysis of persuasive language of 115 print advertisements of beauty products from one year issue of three local magazines. Thorough data analysis showed that persuasive language of print advertising is embedded in indirect convincing through an appeal to emotional needs, an appeal to celebrity image, and an appeal to colonial mentality of consumers. Furthermore, persuasive language is embedded in analogy through the use of metaphor and future events. Results also showed that the syntactic and semantic features of print advertising in Philippine context include the use of adjectives, time expressions, figurative language, clipping, blending, poetic devices, imperatives, code-switching, and problemsolution structure. An interesting social issue generated from the result of the study is the myth of women’s agelessness and perfection.It is recommended that a similar study be conducted to radio and television advertising to improve the practice of advertising language that is reflective of culture, behavior, and educational practices.

Competing Standpoints of Code-Switching in Classroom Instruction of the Pre-Secondary Teachers
Authors: Baquerfo Prescila S.
Published: February 2016

This qualitative study aimed to analyze the types and function of code switching in classroom instruction of the pre-service secondary teachers and to investigate their different standpoints on the use of code- switching in classroom instruction. The results revealed that among the types of code- switching, intra-sentential was the most regular type used by the participant, followed by Intersentential, and the least was tag. The result further revealed that addressee specification came out to be the function that was frequently used by the participants. Reiteration came next followed by message qualification. Interjection and direct quotation were found to have very minimal instances. Personalization or objectivization was never found in the analysis in the three content areas. From the positive negative standpoints, the major themes extracted from the core- ides were interpersonal communication enhancer, lexical difficulty replacer, and lesson enhancer. For the negative standpoints, the major themes were oral communication barrier, habit, vocabulary deficiency and dependent on first language.

Selected Paintings of Davaoeño artists: The Perspective of artists and viewers
Authors: Sagarino Emma V. , Baucan Villalyn B. , Habla Rebecca P.
Published: February 2016

Artwork as a medium of expression reveals themes such as politics, culture, practices, beliefs, environment and many more. The value of artwork may lie on the appreciation given by the viewers. Thus, this study justified whether the youth of today possessed the ability to recognize and understand the messages conveyed through an artwork. Six paintings of two artists from Davao City, Philippines were explored and unveiled. The paintings were shown to 20 purposively chosen students from the University of the Immaculate Conception, Davao City. After the viewing, two separate Focus Group Discussions (FGD) were conducted. The two artists were also interviewed as to the themes and messages they have embodied through their paintings. The common theme conveyed by Engr. Mendros is anchored on Biblical verses. It is understood that his viewers were able to interpret the messages– “The Creation” and Jesus Walking on Top of the Water” because the study participants were composed of Philosophy students who were ex-seminarians. They were able to relate to most of the symbols reflected in the paintings. Mr. Espinosa had revealed Filipino culture and some political issues and many of his viewers were able to express the messages as they were able to relate with them as well.

Portals of Institutional Culture: University Confession Pages in Focus
Authors: Geonzon Christense , Gerasmio Anna , Lanos Khimberly , Salvan Frevilyn , Tagaytay Monique Musni
Published: February 2016

One of the innovations in the social media landscape is the proliferation of confession pages on Facebook which allow social media users to “confess” their thoughts, feelings and experiences without revealing their true identity. Confession pages associated with specific higher educational institutions have become a venue for student revelations about everything and anything pertaining to campus life. This multiple case study ventured to find out if the university confession page serves as a peep hole into institutional culture as revealed by the confessions made by users on Facebook and also to figure out whether users’ perception about their own school as well as other schools is affected by the content that they read on university confession pages. The study selected three higher educational institutions in Davao City as its locale. To obtain thick descriptions of this phenomenon, the researchers triangulated between transcripts of conducted focus group discussions, and open- ended questionnaires and content analysis of actual posts from the selected university confession pages. The data revealed that the cloak of anonymity and absence of direct consequence emboldens those who “confess” and serves much like a freedom wall. The study also reveals that while most informants used the confession page because it is the current “in” thing, reading the posts somewhat changed their perception about their school as the hallowed hall of learning as some posts shed light on events and experiences on campus.

The following classes of prac¬tices are considered: 1) Eastern-Orthodox hesychasm, 2) Hellenistic practices of the Self (practices of the Roman Stoicism, Cynism and Epicureanism) as they are interpreted by Michel Foucault, 3) Far-Eastern practices as they are represented in Zen-Buddhism. The problem of the sacred word in spiritual practice is discussed. A number of comparative observations and conclusions are obtained concerning, in particular, "hot" and "cool" practices and corresponding kinds of verbality, typolog¬ical distinctions of verbality in Eastern and Western anthropological practices, etc.
Courage to Be. Hardiness and Faith
Authors: Krichevec A.N. , Solodushkina M.V.
Published: February 2016

The article presents a comparison between hardiness (the psychological construct by S. Maddi and D.A. Leontiev), the term "courage to be" and the defined conception of faith (by P. Tillich). It is shown, that Hardiness (by S. Maddi), despite author's opinion, appears to be not an operationalization of Tillich's "courage to be", but is a development of one of its aspects. Differences between the interpretation of the term in English and Russian variants of its operationalization are also discussed.
