ANÁLISE DO NÍVEL DE MATURIDADE EM GERENCIAMENTO DE PROJETOS EM UMA AGÊNCIA DE PUBLICIDADE DA REGIÃO DO CARIRI
Authors: Pontes Thiago Bessa , Teixeira Junior Valdi Geraldo
Published: May 2017

O tema gerenciamento de projetos tornou-se para as organizações um fator diferencial para permanência em um mercado altamente competitivo. Tidos como complexos, a maioria dos projetos necessita de um profundo gerenciamento em seu ciclo de vida. Procurar alcançar um maior nível de maturidade em gestão de projetos tem sido uma preocupação constante das organizações que buscam atingir o sucesso em seus projetos. Deste modo, este trabalho expõe um estudo de caso a analisar o nível atual da maturidade em gerenciamento de projetos em uma empresa de publicidade localizada na cidade de Juazeiro do Norte, Ceará. Para isso, foram estabelecidos os seguintes objetivos específicos: a) identificar o nível de maturidade da empresa realizando um estudo comparativo ao modelo Prado-MMGP; b) indicar caminhos a seguir de acordo com o modelo para evoluir ao nível seguinte, e indicando os seguimentos para desenvolver o plano de ações para evolução do nível de maturidade, utilizando o Modelo Prado-MMGP. Conclui-se que a empresa em estudo apresenta o nível 1 (um) da escala de maturidade pelo modelo proposto, o que representa um estágio inicial e que não existe nenhum tipo de iniciativa organizada para implantação do mesmo no ambiente de trabalho. Os projetos são executados e gerenciados de forma isolada, ou seja, tentativas individuais de “boa vontade”, no planejamento, controle, procedimentos padronizados que são utilizados de forma inadequada, uma vez que os projetos dificilmente chegam ao sucesso total. Dessa forma, foi proposto que a implantação de gerenciamento de projetos deva acontecer de forma gradual.

Propiedades psicométricas de la escala de Competencia Intrasexual a Nivel Intergrupal en Costa Rica
Authors: Torres Fernandez David , Smith-Castro Vanessa , Buunk Abraham P.
Published: May 2017

La Escala de Competencia Intrasexual-Intergrupal, diseñada por Klavina, Buunk y Park (2009) evalúa el nivel de competencia intrasexual en la selección de pareja en contextos intergrupales, en relación con extranjeros. Con el fin de proporcionar evidencias de validez de constructo en población costarricense se realizaron dos estudios. Los resultados mostraron que la escala puede ser considerada como una medida unidimensional y que sus puntuaciones correlacionan de forma positiva con medidas de competencia intrasexual, Orientación Sociosexual y Orientación a la Dominancia Social; y de forma negativa con medidas Contacto Intergrupal, Control Inhibitorio y de Valor como Pareja, tal y como se esperaba según la evidencia empírica. Se discute el aporte de esta medida al estudio del comportamiento humano desde la psicología social y la psicología evolucionista.

Published: May 2017

Tem sido a conquista dos últimos anos o reconhecimento das autoras brasileiras dos séculos passados, mias numerosas do que se supunha e que foram esquecidas devido aos preconceitos do canone Literário. A partir da segunda metade do século XIX, com o levantamento dos períodos em todo o país, dirigidos e editados por mulheres e para mulheres, veiculavam as ideias avançadas e, ao mesmo tempo, concepções do sistema patriarcado. O medo do corpo e do erotismo se transmite à produção literária feminina que, ao se inspirar no amor, quase sempre usa linguagem pudica, procuando santificar o sentimento. Mas não raro surgem passagens de uma audácia inesperada, num desafio ostensivo aos convencionalizmos do cânone comportamental. Estudam-se como as escritoreas Ana Ribeiro, Ildefonsa Laura César e Adelio Fonseca, dentro deste contexto

A literatura negra surgiu por força da situação social em que os afrobrasileiros se encontram e da qual a sociedade envolvente não os deixa sair. São muitos os temas escolhidos para apresentar a literatura afrobrasieira. Entre ele, um tema diretametne ligado às lutas contra o jogo do cativeiro e à abolição. Ao lado de expressarem solidariedade e revolta contra a opressão, regozijo pela independência conquistada, assim como repúdio a uma alforria que até hoje contiua incompoleta, poetas como Cuti (Luz Silva), Oswaldo de Camargo, Éle Semog, Olivera Silveira, Domício Proença e outros sentem-se ligados a esses símbolos heróicos, encarnação da luta contra o cativerio degradante. São em parte imagens ao mesmo tempo misticas e míticas, fonte de encorajamento e afirmação, cuja lembrança reforça o sentimento identitário dos filhos da diáspora.
The Iraq Inquiry: UK interests in Iraqi oil
Authors: Khadduri Walid
Published: May 2017

The main official reason given by the Allied powers for invading Iraq in 2003 was to destroy Iraq’s alleged Weapons of Mass Destruction. There was hardly any mention of the role of oil in the war. Iraq’s crude oil reserves are among the five largest globally. This fact did not escape the attention of allied politicians. The Chilcot Report made it clear that public statements on the war should focus on the Weapons of Mass Destruction, and that no mention should be made of oil interests, in order not to antagonize Iraqi public opinion and raise the suspicion that the war is about western control of Iraq’s oil. The Report revealed that scores of meetings took place between UK government officials and leading British oil firms such as BP and Shell to ensure that the firms received a sizeable share of the upstream contracts following the war. The Report also showed concerns raised by British officials of US attempts to stop Russia’s negative position towards the war in the UN Security Council by promising upstream oil contracts to Russian firms. British officials also complained that the United States kept the oil file strictly under its domain, particularly after the war ended. The Report documents beyond doubt the role of oil interests in the war, despite the fact that the subject was not raised publicly by the Allied officials.

Crime TV’s undercover Halloween
Authors: Steenberg Lindsay
Published: May 2017

In order to interrogate patterns of seasonal television, this article looks at Halloween themed episodes of long-running American crime television programmes such as CSI (2000−2015), Bones (2005−) and, in particular, Criminal Minds (2005−). It argues that Halloween on crime TV is predictably transgressive – offering conventional fantasies of masquerade and consumption, rather than subversive challenges to the genre’s status quo. On crime television, Halloween has harnessed the logic of the urban legend to present nostalgic visions of a festival that has become fundamentally televisual in nature. The thematic underpinnings of this televisual holiday are anxieties around children in public space and the ritual re-imagining of the risks they face when celebrating Halloween.

Authors: Predmirskyi V. S. , Tverdohleb N. G.
Published: May 2017

During the test of traveling wave tubes it was ascertained the direct dependence of the thermal conductivity of the slow wave structure from accuracy of manufacturing and from porosity of ceramic support rods. It is allowed to define the need to improve the accuracy of their production and the presorting by porosity.
In this paper it is solved the problem of fastening of the ceramic rods in the process of processing by coolant instead of adhesive layer. The list of technological parameters and modes of machining support rods held by molecular cohesion forces are defined.
The developed system of experiments allowed to determine the processing parameters required for the calculation of the bond strength (due to the liquid layer) of the ceramic support rod with a mandrel in the process of machining. This makes possible to determine the technological process parameters of ceramic supporting bars polishing for TWT slow-wave structure. It is shown the possibility of power approach to the estimation of process parameters.

Electron multiplication charge coupled devices (EMCCD) technology is an innovation first introduced slightly more than a decade ago. The EMCCD is an image sensor that is capable of detecting an isolated photon without an image intensifier. It is achieved by electron multiplication circuit that is built in the chip of ordinary CCD.
Cameras with EMCCD arrays overcome limitations of getting high sensitivity with high frame rate. Traditional CCD cameras can be highly sensitive in the visible part of spectrum but at the expense of low frame rate. EMCCD can operate at very faint illumination conditions both in visible and near infrared regions.
The paper presents a short technological description of EMCCD 640×512 arrays manufacturing and some parameters of the arrays that were designed and manufactured. It was shown that multiplication coefficient depends much on applied amplification voltage and can achieve 1000. Also it is shown that images can be obtained at low illumination conditions (illumination at EMCCD is near 5∙10–4 lx).
The influence of the key limiting factors on the limitations of heat transfer in heat pipes with various working fluids
Authors: Melnyk R. S. , Nikolaenko Yu. E. , Kravets V. Yu. , Alekseik Ye. S.
Published: May 2017

Aluminium and copper heat pipes with grooved and metal fibrous capillary structure are high effective heat transfer devices. They are used in different cooling systems of electronic equipment like a LED modules, microprocessors, receive-transmit modules and so on. However, thus heat pipes have heat transfer limitations. There are few types of these limitations: hydraulic limitation, boiling limitation, liquid entrainment by vapor flow and sonic limitation. There is necessity to know which one of these limitations is determinant for heat pipe due to design process. At a present article calculations of maximum heat transfer ability represented. All these calculations were made for LED cooling by using heat pipes with grooved and metal fibrous capillary structures. Pentane, acetone, isobutane and water were used as a coolants. It was shown that the main operation limit for axial grooved heat pipe, which determinate maximum heat transfer ability due to inclination angle for location of cooling zone higher than evaporation zone case, is entrainment limit for pentane and acetone coolants. Nevertheless, for isobutane coolant the main limitation is a boiling limit. However, for heat pipes with metal fibrous capillary structure the main limitation is a capillary limit. This limitation was a determinant for all calculated coolants: water, pentane and acetone. For high porosity range of capillary structure, capillary limit transfer to sonic limit for heat pipes with water, that means that the vapor velocity increases to sonic velocity and can’t grow any more. Due to this, coolant cant in a needed quantity infill condensation zone and the last one drained. For heat pipes with acetone and pentane, capillary limit transfer to boiling limit. All calculations were made for vapor temperature equal to 50°C, and for porosity range from 30% to 90%.

Published: May 2017

Cell‐autonomous circadian oscillations strongly influence tissue physiology and pathophysiology of peripheral organs including the heart, in which the circadian clock is known to determine cardiac metabolism and the outcome of for instance ischemic stress. Human pluripotent stem cells represent a powerful tool to study developmental processes in vitro, but the extent to which human embryonic stem (ES) cell‐derived cardiomyocytes establish circadian rhythmicity in the absence of a systemic context is unknown. Here we demonstrate that while undifferentiated human ES cells do not possess an intrinsic functional clock, oscillatory expression of known core clock genes emerges spontaneously during directed cardiac differentiation. We identify a set of clock‐controlled output genes that contain an oscillatory network of stress‐related transcripts. Furthermore, we demonstrate that this network results in a time‐dependent functional response to doxorubicin, a frequently used anti‐cancer drug with known cardiotoxic side effects. Taken together, our data provide a framework from which the effect of oscillatory gene expression on cardiomyocyte physiology can be modeled in vitro, and demonstrate the influence of a functional clock on experimental outcome.

Background: Hypothermic circulatory arrest includes a remarkable risk for neurological injury. Diazoxide, a mitochondrial adenosine triphosphate–dependent potassium ion (K+ATP) channel opener, is known to have cardioprotective effects. We assessed its efficacy in preventing ischemic injury in a clinically relevant animal model. Methods: Eighteen piglets were randomized into a diazoxide group (n = 9) and a control group (n = 9). Animals underwent 60 minutes of hypothermic circulatory arrest at 18°C. Diazoxide (5 mg/kg + 10 mL NaOH + 40 mL NaCl) was infused during the cooling phase. Metabolic and hemodynamic data were collected throughout the experiment. After 24-hour follow-up, whole brain, heart, and kidney biopsy specimens were collected for analysis. Results: Cerebellar Cytochrome-C and caspase-3 activation was higher in the control group (P = .02 and P = .016, respectively). Antioxidant activity tended to be higher in the diazoxide group (P = .099). Throughout the experiment, the oxygen consumption ratio was higher in the control animals (Pg = .04), as were the lactate levels (Pg = .02). Cardiac function tended to be better in diazoxide-treated animals. Conclusion: Diazoxide might confer neuroprotective effect as implied by the immunohistochemical analysis of the brain. Additionally, the circulatory effects of diazoxide were beneficial, supporting its neuroprotective effect.

Published: May 2017

Myxoma is the most commonly found cardiac primary tumor. The left atrium is the most common localization of myxoma, followed by the right atrium. However, it is rare in the left and right ventricles. Myxoma originating from cardiac valves is extremely rare. This article presents a case of a 17-year-old male who was admitted due to heart murmur for one year. Transthoracic echocardiography indicated a 1.9 cm round solid mass in the left ventricular outflow tract. Excision surgery and aortic valve replacement were performed in this patient. Histopathology revealed the mass as a myxoma. The aortic valve remains a very rare myxoma localization position. Echocardiography can provide a precise method for myxoma diagnosis. Early excision associated with valve replacement can provide good curative effects.

Published: May 2017

Background

Mount Oyama, on the Japanese island of Miyakejima, began erupting in June 2000, necessitating the evacuation of 3,000 island residents. Volcanic gas emissions, primarily consisting of sulfur dioxide (SO2), gradually decreased and residents returned to the island after the evacuation order was lifted in February 2005.

Objectives

To assess the exposure-effect and exposure-response relationships between SO2 exposure and effects on respiratory system in adult Miyakejima residents.

Method

Health checkups focusing on pulmonary function and respiratory/irritative symptoms were conducted six times every November from 2006 to 2011. The study population comprised 168 subjects who underwent all health checkups. SO2 concentrations were measured at six fixed monitoring stations in inhabitable areas.

Result

Based on the annual mean SO2 concentration, inhabitable areas were classified into three categories; namely, lower (L), higher (H-1), and highest (H-2) areas. Average SO2 concentrations (ppb) during 3 months prior to each health checkup dropped from 11.3 to 3.29, 32.2 to 13.4 and 75.1 to 12.6 from 2006 to 2010/2011 in L, H-1, and H-2. No significant declines in pulmonary function were observed in all areas. However, prevalence of subjective symptoms such as “Cough,” “Irritation and/or pain in throat,” “Irritation, runny nose, and/or nasal sniffles,” and “Irritation and/or pain in the eyes,” dependently increased on SO2 concentration. Odds ratios were statistically significant at approximately 70 ppb of SO2 or above.

Conclusion

Adult residents of Miyakejima island showed no deterioration in pulmonary function at SO2 levels, but complained of respiratory/irritative symptoms in an SO2 concentration-dependent manner.

Published: May 2017

Brucellae are Gram-negative cocccobacilli, facultative intracellular bacterial pathogens of both humans and animals. Brucellosis is an important disease that is difficult to diagnose and treat that causes heavy economic losses and human suffering. Diagnosis of brucellosis plays a vital role for control and prevention of the disease. Lipopolysaccharide (LPS) based Enzyme Linked Immuno Sorbent Assay (ELISA) shows false positivity due to cross-reactivity with other gram-negative bacteria LPS. The present investigation was undertaken to assess the diagnostic potential of the recombinant P17 protein of Brucella. P17 gene of Brucella abortus (B. abortus) was amplified, cloned and subcloned into pQE 30 vector yielding high levels of protein expression. The purified recombinant P17 (rP17) protein was used to develop an indirect ELISA (i-ELISA) test for brucellosis. The rP17-ELISA was compared with RBPT (Rose Bengal Precipitation Test) and LPS-ELISA using 530 cattle sera. The concordance percentage and kappa statistics of P17-ELISA is greater in compression with LPS-ELISA. Relative sensitivity and relative specificity of P17-ELISA shows a positive trend with RBPT. The data suggest that P17-ELISA can be a useful method for Brucella diagnosis and recombinant P17 protein is a potential antigen for diagnosis of cattle brucellosis.

Published: May 2017

Pasteurella multocida is a Gram negative bacterium causing severe disease in a multitude of hosts; the A: 1 strain of this bacterium is extremely virulent to hosts. In this study, the virulence of P. multocida A: 1 strain was assessed in one month old ducklings, six months old ducks and eight weeks old albino mice. The groups of experimental animals were inoculated with the different dilutions of the bacteria through subcutaneous route. The control groups were sham inoculated with sterile phosphate buffered saline via respective routes. Mortality was recorded for two weeks post inoculation. All the dead animals and birds were examined for specific gross lesions of pasteurellosis and attempted re-isolation of the organism on blood agar from their internal organs. The median lethal dose was calculated using Reed and Muench method. For ducklings, the median lethal dose was 13 colony forming units and the dilution giving 50 % end point with 0.1 ml subcutaneous dose was 10-7.4. The median lethal dose could not be arrived at for mice and adult ducks as the strain killed all the inoculated mice even in the lowest dilution tested, while most of the adult ducks were resistant to infection.

Published: May 2017

Ordered GaAs micro crystal growth on a As-terminated Si (001) surface was demonstrated using a low energy focused ion beam. Si (001) surface was terminated by Arsenic. The surface showed a (2×1) structure with As dimers. The As layer was sputtered periodically with low energy focused Ga ion beam. Supplied Ga atoms migrated on the surface and trapped at the As removed region, forming Ga droplets. GaAs micro crystals were grown from Ga droplets by As molecule supply. The proposed method was shown to be effective as a fabrication method.

Published: May 2017

Pressure induced structural phase transformation in nanocluster assembled GaAs is studied using parallel molecular dynamics simulations in the isothermal-isobaric ensemble. In this system the spatial stress distribution is found to be inhomogeneous. As a result structural transformation initiates in the high stress regions at the interface between clusters. Structural and dynamical correlations in the nanophase system are characterized by calculating the spatially resolved bond angle and pair distribution functions and phonon density of states and comparing them with those for a single cluster and bulk crystalline and amorphous systems.

ABSTRACT: The aim of this research was to evaluate the interaction between maturity stages and temperature on fruit quality of ‘Guarani’ blackberries stored under controlled atmosphere (CA). The experiment was conducted in a factorial scheme (2x2), evaluating two ripening stages (E1: red-color and E2: black-color of fruits) and two temperatures (1°C and 5°C). The fruit were stored in CA (10.0kPa O2+15.0kPa CO2) and 98±1% of relative humidity (RH). Results showed that the principal component 1 (PC I) and principal component 2 (PC II) corresponded to 92.84% of the overall variation of the evaluated variables. Harvest should not be performed in the early maturity stage, because ‘Guarani’ blackberries do not develop all quality of consumer. ‘Guarani’ blackberries must be stored at 1°C. The maturity stage showed the major importance in the overall variability of quality parameters when compared to storage temperature.
Pesticide selectivity to natural enemies: challenges and constraints for research and field recommendation
Authors: Bueno Adeney de Freitas , Carvalho Geraldo Andrade , Santos Antônio Cesar dos , Sosa-Gómez Daniel Ricardo , Silva Débora Mello da
Published: May 2017

ABSTRACT: Pesticides are considered the first line of defense for the control of pests and diseases. At least in the short and medium term, the use of pesticides will remain an important strategy for pest management, allowing growers to produce crops of sufficient quality at low costs. A broad approach known as Integrated Pest Management (IPM) combines several different pest-control strategies, among which the combination of chemical and biological control stands out. It requires pesticides that achieve optimal control of target pests with minimal impact on the activity of biological control agents. Because of the dynamics of pest infestations, IPM routines are continuously adjusted by growers, requiring comprehensive information about pesticide effects on natural enemies. However, this information is not always available and often contradictory, which constrains the design of field recommendations. In this review, we focused on the importance of selective pesticides in IPM programs, and the effects of chemical pesticides on parasitoids, predators, and entomopathogenic fungi. We provided a detailed discussion of the challenges and constraints for research on pesticide effects on natural enemies, as well as for the resulting field recommendations.

Resumo O envelhecimento é um processo natural do ser humano, mas que socialmente acarreta exclusão do indivíduo da comunidade em que está inserido. De modo a contornar tal situação e reinserir o idoso na sociedade, instituições têm oferecido cursos especiais, com ênfase para os cursos de língua estrangeira (PEREIRA, 2005). O presente relato é fruto de uma experiência de ensino de língua italiana para alunos idosos, e tem como objetivo enfatizar os fatores motivadores que levaram tal público às aulas de língua estrangeira, suas crenças, dificuldades e necessidades, bem como a concepção do aluno idoso sobre a cultura da língua meta (HALL, 2011; KUMARAVADIVELU, 2012). Ressaltamos alguns conflitos que se mostraram evidentes em sala de aula e que estão em concordância com os estudos atuais.
A bioética de proteção: uma ferramenta para a avaliação das práticas sanitárias?
Authors: Schramm Fermin Roland
Published: May 2017

Resumo A bioética de proteção (BP) é uma proposta que surge no começo do Século XXI no âmbito da bioética construída na América Latina e no contexto das tentativas de pesquisadores de pensar as condições de possibilidade de uma bioética sanitária, preocupada inter alia com as políticas públicas de saúde, para que sejam moralmente legítimas, socialmente justas (equitativas) e respeitosas dos Direitos Humanos, após constatar os limites das ferramentas bioéticas tradicionais, essencialmente aplicadas somente aos conflitos interpessoais dos agentes e pacientes morais envolvidos nas práticas da biomedicina. Do ponto de vista metodológico, a BP tenta agenciar âmbitos disciplinares problemáticos distintos, mas vinculados entre si pelo diálogo interdisciplinar e a preocupação comum com a qualidade de vida das populações humanas, consideradas em seus contextos naturais, tecnológicos, sociais e culturais: a Saúde Pública, preocupada com a saúde e o bem-estar de indivíduos e populações; a Bioética, preocupada prioritariamente com a legitimidade moral de práticas que afetam sua qualidade de vida; a Biopolítica, preocupada com os efeitos sociais das políticas sanitárias.

Foram realizadas análise de documentos e entrevistas com informantes-chave da esfera governamental e profissionais. O artigo caracteriza o Comitê Técnico Assessor como uma “comunidade de especialistas”, definida como uma rede de indivíduos com proficiência e competência em uma esfera particular, cujo conhecimento se mostra relevante em áreas críticas da decisão de política pública. Também demonstra que o processo decisório para a incorporação de antirretrovirais ao programa brasileiro foi fortemente incremental, contemplando as expectativas das empresas inovadoras líderes de mercado farmacêutico. O trabalho descreve, assim, os resultados da interação de interesses do governo, indústria farmacêutica e especialistas na implantação de uma política de relevância internacional. Oferece argumentos e evidências para o entendimento do papel de comunidades de especialistas em uma política pública setorial até agora analisada predominantemente sob a ótica dos movimentos sociais.
A relação de incerteza de Maccone-Pati
Authors: Maziero Jonas
Published: May 2017

A existência de observáveis incompatíveis em mecânica quântica (MQ) é uma das suas características mais notáveis e pode ser revelada e formalizada através de relações de incerteza. A relação de incerteza de Heisenberg-Robertson-Schrödinger (RIHRS) foi provada nos primórdios do formalismo quântico e está unipresente tanto no ensino quanto na pesquisa em MQ. Todavia, a RIHRS possui o chamado problema da trivialidade, ou seja, ela não fornece informação alguma sobre a possível incompatibilidade entre dois observáveis se o estado no qual o sistema foi preparado for autovetor de um deles. Este problema foi resolvido recentemente por Lorenzo Maccone e Arun K. Pati, depois de aproximadamente 85 anos de existência da RIHRS. Neste artigo começamos fazendo uma breve discussão sobre aspectos gerais do princípio de incerteza em MQ e recapitulando a prova da RIHRS. Na sequência apresentamos de forma simples a prova da relação de incerteza de Maccone-Pati, que pode ser obtida usando basicamente a lei dos paralelogramos e a desigualdade de Cauchy-Schwarz.

ABSTRACT Mangaba is a widely-consumed fruit in the Northeast of Brazil, which is usually exploited through extractivism. This fruit is rich in various nutrients, especially in vitamin C, with pleasant taste and aroma. The lyophilization process transforms these fruits into amorphous powders, which must be analyzed regarding their properties and hygroscopic trend. Thus, the objective of this study was to characterize and evaluate the physico-chemical properties of adsorption isotherms of the lyophilized ‘mangaba’ pulp powder, with addition of maltodextrin (DE 20). The pH, titratable acidity, soluble solids, ascorbic acid and water activity were analyzed. Regarding the isotherms, the mathematical models of GAB, BET, Oswin, and Henderson were used at temperatures of 25, 30, 35 and 40 °C. The obtained powder presented pH of 3.14, titratable acidity of 1.95 mg of citric acid 100g-1 of powder, soluble solid contents of 99 ºBrix, ascorbic acid content of 55.97 mg 100g-1 and water activity of 0.16. Henderson was the mathematical model that best fitted the data of the adsorption isotherms at the four evaluated temperatures, with average errors ranging from 5.76 to 9.70% and R2 from 0.9974 to 0.9995.

RESUMO Objetivo O objetivo desta pesquisa foi verificar se há melhora funcional do padrão de deglutição em indivíduos identificados com risco para disfagia orofaríngea após quatro semanas da realização de exercícios orofaríngeos específicos com intensidade e duração pré-determinados. Método Esta pesquisa é de caráter longitudinal de efeito funcional, determinado por medidas comparativas inicial e final. A população-alvo foi constituída de indivíduos adultos e idosos selecionados por 24 meses. Foi incluído para esta pesquisa um total de 68 indivíduos. Foi realizada avalição clínica da deglutição e observados sinais clínicos para disfagia. Os indivíduos foram divididos em dois grupos de acordo com o nivelamento inicial na escala ASHA NOMS. No Grupo 1 (G1) – ASHA NOMS, inicial de níveis 1 e 2; Grupo 2 (G2) – ASHA NOMS, inicial de níveis 3, 4 e 5. Todos os indivíduos realizaram um protocolo de exercícios por quatro semanas. O protocolo conta com sessões presenciais e continuidade das atividades em ambiente domiciliar. Ao final, foi realizada nova mensuração do desempenho de deglutição. Resultados Para o grupo G2 houve melhora estatisticamente significante. Para o G1, a relação não foi significante, apesar de mudança intensa na escala ASHA NOMS, porém, neste grupo, temos um número reduzido de indivíduos devido à gravidade do perfil. Conclusão O programa se mostrou efetivo, pois, após as quatro sessões de exercícios, houve melhora importante no padrão de deglutição, demonstrada pela escala funcional.

RESUMO Objetivo Verificar a queixa subjetiva de memória relacionada com a fluência verbal em idosos participantes de grupos de convivência. Método Trata-se de um estudo epidemiológico, quantitativo, realizado em grupos de convivência de idosos do município de Florianópolis, Estado de Santa Catarina. Os dados foram coletados por meio de entrevista estruturada utilizando-se o Questionário de Queixas de Memória (MAC-Q) e o Teste de Fluência Verbal (TFV) por categorias semânticas animais/minuto. Para a análise descritiva inferencial, consideraram-se os dados com p < 5%. Resultados Foi encontrada a queixa de memória autodeclarada em 35,7% da amostra. Não houve associação e correlação do TFV com a percepção da memória obtida pelo MAC-Q bem como com o seu escore. A análise do TFV com os indivíduos que referiram percepção negativa de memória apresentou significância estatística. Salienta-se que foi encontrada associação significativa entre a percepção (escore do MAC-Q) e a presença da queixa de memória (referida pelos idosos em questão acrescida ao questionário). Conclusão Não houve relação entre a queixa subjetiva de memória e a fluência verbal de idosos ativos, sendo as queixas mnemônicas correlacionadas à percepção negativa da memória e ao tempo de queixa apresentada. Porém a queixa subjetiva da memória se mostrou um indicativo para aqueles indivíduos com percepção negativa da memória, sendo um aspecto que deve ser considerado na fala dos idosos ao se investigar um possível declínio cognitivo. Tais dados podem auxiliar no direcionamento das ações de políticas públicas de assistência às pessoas idosas no município, salientando-se a importância em se verificar a queixa subjetiva de memória dos idosos.

Published: May 2017

RESUMO Objetivo Verificar as habilidades do processamento auditivo e a ocorrência do efeito de supressão das emissões otoacústicas em indivíduos com gagueira. Método Participaram 15 adultos com gagueira, de 18 a 40 anos, com grau de severidade variando de leve a severo, pareados por gênero, faixa etária e escolaridade com indivíduos sem queixa ou alteração de comunicação. Todos passaram por avaliação fonoaudiológica convencional, avaliação específica da gagueira, avaliação audiológica básica (audiometria, imitanciomentria e pesquisa dos reflexos acústicos) e específica (avaliação do processamento auditivo e pesquisa do efeito de supressão das emissões otoacústicas). Os dados foram submetidos à análise estatística, com aplicação do Teste Exato de Fisher e do Teste de Mann-Whitney. Resultados O grupo de gagos apresentou maior ocorrência de alterações de processamento auditivo. Os testes do processamento auditivo que diferenciaram os grupos de gagos e não gagos foram o Teste Dicótico não Verbal e o Teste Padrão de Frequência. O grupo de gagos apresentou maior ocorrência de ausência do efeito de supressão das emissões otoacústicas, indicando anormalidade do funcionamento do sistema eferente olivococlear medial. Conclusão: As habilidades do processamento auditivo investigadas neste estudo diferem indivíduos gagos e não gagos, com maior alteração nos gagos. O funcionamento do sistema eferente olivococlear medial mostrou-se deficitário nos indivíduos gagos, indicando dificuldade de discriminação auditiva, principalmente na presença de ruído.
Texture as Substance: Reading Homi K. Bhabha Re-membering Frantz Fanon
Authors: Schwarz Henry
Published: May 2017

[T]he idea of Man as his alienated image, not Self and Other but the “Otherness” of the self inscribed in the perverse palimpsest of colonial identity. (116)

According to Isaac Julien, the director of Black Skin, White Mask, a film imagining the life of Frantz Fanon, Homi Bhabha is presented in a nonspeaking role as a colored, racialized “colonial subject” to lend “texture” to the cinematography (Interview). Unlike the eloquent postcolonial critics Stuart Hall and Françoise Vergès, who are interviewed extensively in the ilm, the mute Bhabha is a cipher, a visual trace of diference in the philosophical, cinematic, and audio montage that composes Julien's meditation on decolonization (Frantz Fanon [Director's cut]). In many ways, Julien's Fanon seems indebted to Bhabha's strong reading, against the grain of Fanon's oeuvre, in “Remembering Fanon: Self, Psyche and the Colonial Condition,” a foreword Bhabha wrote for a new British edition of Fanon's Black Skin, White Masks, published in 1986. Julien's Fanon is an interstitial igure, stitched together through multiple viewpoints and physically composed of cinematic elements juxtaposed in striking contrast to one another. He emerges from scraps of discourse cast of and reassembled, much as Bhabha's Fanon is captured in Fanon's ungrammatical utterance that betrays by ellipsis the nature of identity, which is that identity is “not”: “The Negro is not. Any more than the white man” (113). The revelation that the nature of identity is spatially split and temporally deferred-the deinition of Derridean diférance-is most truly represented in the colonial situation, where white mythologies of wholeness and authenticity are actualized as performances of power. When these mythologies are accompanied by paranoid fantasies of blackness that reveal the contradictory duplicity of white representations of the other-the simian Negro, the inscrutable Chinaman-this racial discrimination and its neurotic imagery reveal the nature of the white self and its pretense of universality: that the human is not whole and that the Enlightenment dream of self-presence is an illusion thrown up by the anxious exercise of mastery over those lesser humans, the Negroes.
Before Normal, There Was Natural: John Bulwer, Disability, and Natural Signing in Early Modern England and Beyond
Authors: Bearden Elizabeth B.
Published: May 2017

Disability studies scholars and Renaissance scholars have much to learn from early modern schemata of disability. Early modern people used nature and the natural to discriminate against and to include people with atypical bodies and minds. In his writings, the English physician John Bulwer (1606–56) considers Deafness a natural human variation with definite advantages, anticipating current concepts of biolinguistic diversity and Deaf-gain, while acknowledging his society's biases. He refutes the exclusion of sign language and other forms of what he calls “ocular audition” from natural law, which made capacity for speech the benchmark for natural rights. Instead of using Deaf people as exceptions that prove the rule of nature or as limit cases for humanity, Bulwer makes deafness part of a plastic understanding of the senses, and he promotes the sociability of signed languages as a conduit to a universal language that might be encouraged and taught in England.
The Implications of federalism and decentralisation on socio-economic conditions in Ethiopia
Authors: Zimmermann-Steinhart Petra , Bekele Yakob
Published: May 2017

This paper analyses impacts of the federal system and the decentralisation of functions to the district level on Ethiopia's socio-economic development. Firstly we will highlight the principles of the Ethiopian federal system as well as those of the 2001/2002 decentralisation process. Secondly we will show how the decentralisation has impacted on two of the decentralised sectors, health and education, by comparing pre-federal, pre- and post-decentralisation data.In both cases an overall increase in allocated budgets and an increase in the scale of the services offered since decentralisation started in 2001 has been found. Studies also show that the increase in services is not homogenous across regional states. Within the four larger regions, strongly disadvantaged woredas at the outset of the decentralisation process have profited most, which shows that the constitutional imperative of equal access to services is being implemented. Some of the regions where decentralisation was started later have still not caught up with the other regions, a phenomenon which is mostly due to capacity deficits.The article concludes that decentralisation in combination with consistent development policies has led to an overall improvement in service delivery, while some challenges regarding quality and equity still need to be addressed.
