A Comparative Study of the Activity of TiO2 Degussa P25 and Millennium PCs in the Photocatalytic Degradation of Bromothymol Blue
Authors: Bouanimba Nour , Laid Nassima , Zouaghi Razika , Sehili Tahar
Published: October 2017

The photocatalytic activities of TiO2 Degussa P25 and Millennium PCs (PC50, PC100, PC105 and PC500) were evaluated by the photocatalytic degradation of Bromothymol Blue (BTB). The relationship between the photocatalytic reaction and the adsorption of BTB on the TiO2 catalysts at acidic, natural and basic mediums of pH was investigated. The crystalline phase, average crystalline size and surface area of the catalyst were found to have a significant influence on the adsorption and photocatalytic activity of the TiO2 samples. The mixed phase of anatase/rutile (Degussa P25) was found to be the most efficient photocatalytical material than pure phase anatase (Millennium PCs) and faster degradation is observed for PC500 compared to other Millennium PCs, this was attributed to the high surface area of PC500. Within the PC50, PC100 and PC105 series, the photocatalytic efficiency increased with the decrease of the surface area. The COD and TOC removals increased slowly, however, the decolorization ratio of BTB increased rapidly at the same time. Thereafter, the efficiency of P25 and PC500 were compared in presence of H2O2, Cl− and HCO3− at different mediums of pH. H2O2 was found to enhance strongly the BTB degradation in presence of P25 with an optimum at natural pH. In contrast, the reaction was inhibited in the presence of PC500, due to the inhibition of dye adsorption. At different pH, the BTB degradation has been significantly inhibited in the presence of the mixtures of HCO3−/H2O2. In contrast, the mixtures of Cl−/H2O2 accelerate the BTB degradation at acidic pH.

Published: October 2017

Introduction: Due to their immunostimulatory properties TLR ligands are used prophylactically to protect against a variety of viral and bacterial pathogens in mammals. Knowledge of the molecular and functional aspects of TLRs is essential for a better understanding of the immune system and resistance to diseases in birds. For that reason, this study attempted to determine the impact of TLR21 stimulation by its synthetic ligand (CpG ODN, class B) on the chicken immune system.

Material and Methods: Sixty embryonated chicken eggs were randomly allocated into three groups (control and two experimental groups). On day 18 of embryonic development, chickens in one experimental group were administered in ovo a low dose of CpG ODN and the birds of the second experimental group were given a high dose of the ligand. Spleens were collected at 1, 2, 5, and 10 days post-hatching (dph) for analysis of IFN-α, IFN-β, IFN-γ, IL-6, and IL-10 expression using qRT-PCR.

Results: Significant differences were observed in mRNA expression levels of all the measured cytokines associated with the modulation and regulation of the immune response at different time points.

Conclusion: The obtained data clearly demonstrate that immune response induction takes place after in ovo administration of class B CpG ODN, and that the ligand has the ability to induce cytokine responses in neonatal chicken spleen.
Evaluation of Translation through the Proposal of Error Typology: An Explanatory Attempt
Authors: Akbari Alireza , Segers Winibert
Published: October 2017

In the area of translation studies, the real concern of all translators is to produce an acceptable practical translation. With this in mind, one of the critical issues is to pinpoint a good translation through translation evaluation and the types of the errors in which the translator might encounter during translation. Various methods of evaluation such as holistic method, analytic method, calibrated dichotomous items (CDI) and finally preselected items evaluation (PIE) method (Kockaert and Segers 2017), along with various approaches which have been mentioned can be applied for all kinds of translation. To do this, the research is framed to illustrate a proposed framework of error typology to evaluate translation from English into Persian in a university setting. The proposed error typology involves four interconnected parts as the source of errors, error types, error consequences, and lastly error significance, which all consist of some sub-categories. This research paper is an undergoing project with the aim of applying the mentioned framework to more data to see its efficacy.

Published: October 2017

Technical communication is a new field of work compared to other professions, and therefore it does not have a standardised curriculum. In Europe, many technical communicators do not have qualifications in the area. TecCOMFrame, a project funded by the European Union, aims to develop an academic competence framework and higher education prototype curricula at various levels that correspond to the European Framework of Qualifications. The project team has developed the competence framework, comprising six dimensions and 22 subjects. The team is currently developing prototype curricula, including one curriculum which is a focus of this paper, a specialisation stream in technical communication in a Master’s in Translation Studies.

Des Translators neue Kleider. Die Translationwirtschaft in Zeiten von Digitalisierung, Datafizierung und Big Data Management
Authors: Forstner Martin
Published: October 2017

The Internet of things will influence all professional environments, including translation services. Advances in machine learning, supported by accelerating improvements in computer linguistics, have enabled new systems that can learn from their own experience and will have repercussions on the workflow processes of translators or even put their services at risk in the expected digitalized society. Outsourcing has become a common practice and working in the cloud and in the crowd tend to enable translating on a very low-cost level. Confronted with promising new labels like Industry 4.0 and Work 4.0, professional freelance translators will have to organize themselves as smart offices by integrating digitalization and datafication and Big Data Management. Most probably, those developments will change translation training and services in the professional world of translation industry.
Twiplomacy: the meaning of social media to public diplomacy and foreign policy of Lithuania
Authors: Dumčiuvienė Aušra
Published: October 2017

Importance of public diplomacy for states foreign policy implementation and image formation continued to grow over past few decades. New communication technologies provided new means for more successful public diplomacy implementation. The aim of this article is to examine the role of twiplomacy in states foreign policy implementation. Twiplomacy is quite new phenomenon, but its significance is undeniable. A lot of states leaders, governmental institutions, diplomatic missions and diplomats have accounts in Twitter and use it for promoting foreign policy goals and developing positive image of state. Social networks are used to implement states’ public diplomacy, because they provide opportunity to reach mainstream audiences, to develop dialogue amongst politicians and wider audiences and influence people opinion on important issues.

Published: October 2017

Esophageal xanthoma is a rare lesion which is an asymptomatic small yellowish polyp, and most of the reported cases were solitary lesion. Histologically, aggregations of foam cells are found under the papillary hypertrophic squamous epithelium and the foam cells express CD68. The etiology of esophageal xanthoma is unknown. The focal irritation of the esophageal mucosa and infiltrated inflammatory cells are presumed to contribute to its pathogenesis. Although the pathogenesis may be associated with inflammation, the type and nature of the macrophages remain unclear. Here we report a 46-year-old male with esophageal xanthoma, which was incidentally found by endoscopy. Histologically, acute inflammation was not noted, and immunohistochemistry revealed that the foam cells seen in this case of esophageal xanthoma expressed increased levels of M2 macrophage markers. These findings suggest that esophageal xanthoma is associated with late inflammatory and reparative processes long after the initial inflammation of esophageal squamous epithelium.

Published: October 2017

Situated in social capital theory, the purpose of this mixed-methods study was to investigate the relationship between African-born immigrant parents’ educational level, income status, family structures, and academic performance of their children in the United States (U.S.). To that end, 205 African-born immigrant parents from a metropolitan city in the U.S. were surveyed using the modified Longitudinal Immigrant Student Adaptation Questionnaire. The participants’ (N= 205) responses to the questionnaires were analyzed using Chi-square tests and the participants’ (n = 45) interview responses were analyzed using ATLAS.ti qualitative analysis software. Findings from the quantitative data showed relationships between parents’ income, educational level, family structures and academic performance of their children. Interview findings revealed that hard work and resilience to succeed, parental expectations and academic goals, parental support and investment in education, parental involvement, parent-teacher interactions, and parental educational experiences influenced parents to support their children’s education. The authors discuss the implications of these findings for teachers who are tasked to render better educational settings for African immigrant students to succeed in United States schools.

Authors: Gołąb Agnieszka , Nowak Sebastian , Szczygieł Elżbieta
Published: October 2017

Introduction: Foot pain is highly prevalent among persons of all ages. Despite a common belief that it is necessary to perform exercises, there is a scarcity of data regarding their effectiveness. This study sought to assess the effects of a training programme on an improvement in foot function and a reduction in pain.

Material and methods: The study group consisted of 15 females with foot pain and flat foot who performed a daily set of 5 exercises for 6 weeks. The Foot Posture Index, a pedobarographic platform postural examination, functional tests (a unipedal stance test with eyes open and closed as well as a bipedal calf raise test) and the Polish translation of the Foot and Ankle Outcome Score (FAOS) were employed to assess the results. These assessment tools were used before and after the intervention.

Results: Pedobarographic examinations showed an increase in total support surface as well as a decrease in maximum and average plantar pressures and pressures in particular areas of both feet. The FAOS revealed a reduction in pain and an improvement in the remaining aspects under examination in the majority of participants. No significant differences in the results of functional tests were noted.

Conclusions: The exercise programme implemented in the study produces positive outcomes in terms of changes in plantar pressure distribution and leads to a significant reduction in foot pain.

Published: October 2017

Introduction: Upper crossed syndrome is a postural syndrome, with myofascial and functional imbalance within the shoulder girdle and the cervical spine. The therapy usually includes myofascial techniques or massage. The aim of this work was to indicate which of these forms of therapy is more effective in terms of myofascial release.

Material and methods: The study group consisted of 18 individuals (12 females and 6 males) with upper crossed syndrome who were randomly assigned to one of the two groups. In group 1 (8 females, 1 male), rehabilitation protocol involved myofascial techniques, while in group 2 (4 females, 5 males), massage was performed. In both groups, the therapy consisted of five 30-minute daily sessions. Prior to the therapy, on the 1st and the 5th day of the therapy immediately after the intervention as well as 14 days after the therapy completion, suprasternale height was measured and the cervical spine mobility was examined.

Results: It was revealed that both forms of the therapy resulted in an increase in the range of motion of the cervical spine, particularly in the case of the right flexion and right rotation. Effects were still present two weeks after the therapy. After 5 days of rehabilitation, both forms of the therapy led to a significant increase in suprasternale height (p<0.05).

Conclusions: Both myofascial techniques and massage result in an increase in the cervical spine and chest mobility in the longitudinal dimension in persons with upper crossed syndrome.

Serotonin Decreases the Gain of Visual Responses in Awake Macaque V1
Authors: Seillier Lenka , Lorenz Corinna , Kawaguchi Katsuhisa , Ott Torben , Nieder Andreas , Pourriahi Paria , Nienborg Hendrikje
Published: October 2017

Serotonin, an important neuromodulator in the brain, is implicated in affective and cognitive functions. However, its role even for basic cortical processes is controversial. For example, in the mammalian primary visual cortex (V1), heterogenous serotonergic modulation has been observed in anesthetized animals. Here, we combined extracellular single-unit recordings with iontophoresis in awake animals. We examined the role of serotonin on well-defined tuning properties (orientation, spatial frequency, contrast, and size) in V1 of two male macaque monkeys. We find that in the awake macaque the modulatory effect of serotonin is surprisingly uniform: it causes a mainly multiplicative decrease of the visual responses and a slight increase in the stimulus-selective response latency. Moreover, serotonin neither systematically changes the selectivity or variability of the response, nor the interneuronal correlation unexplained by the stimulus (“noise-correlation”). The modulation by serotonin has qualitative similarities with that for a decrease in stimulus contrast, but differs quantitatively from decreasing contrast. It can be captured by a simple additive change to a threshold-linear spiking nonlinearity. Together, our results show that serotonin is well suited to control the response gain of neurons in V1 depending on the animal's behavioral or motivational context, complementing other known state-dependent gain-control mechanisms.

SIGNIFICANCE STATEMENTSerotonin is an important neuromodulator in the brain and a major target for drugs used to treat psychiatric disorders. Nonetheless, surprisingly little is known about how it shapes information processing in sensory areas. Here we examined the serotonergic modulation of visual processing in the primary visual cortex of awake behaving macaque monkeys. We found that serotonin mainly decreased the gain of the visual responses, without systematically changing their selectivity, variability, or covariability. This identifies a simple computational function of serotonin for state-dependent sensory processing, depending on the animal's affective or motivational state.
A Newer Hamas? The Revised Charter
Authors: Hroub Khaled
Published: October 2017

On 1 May 2017, Hamas released its “Document of General Principles and Policies” following years of periodic speculation that the movement was working on a new political platform. Heralded by some as a significant milestone in Hamas's political thought and practice, the document reiterates longstanding positions but also lays out some new ones. Given the timing of its release, as well as its contents and possible implications, the document could be considered Hamas's new charter: it details the organization's views on the struggle against “the Zionist project” and Israel and outlines its strategies to counter that project. This essay aims to provide a fine-grained analysis of the substance, context, and ramifications of the recently released document. The discussion starts with an overview highlighting aspects of the document that could be considered departures from Hamas's original 1988 charter, and pointing to changes in the movement's discourse, both in form and substance. A contextual analysis then probes the regional, international, and internal impetuses behind the issuance of the document. Finally, the discussion concludes with a look at the possible implications for the movement itself, as well as for the Palestinians and for Israel.

A Horizontally Transferred Autonomous Helitron Became a Full Polydnavirus Segment in Cotesia vestalis
Authors: Heringer Pedro , Dias Guilherme B , Kuhn Gustavo C S
Published: October 2017

Bracoviruses associate symbiotically with thousands of parasitoid wasp species in the family Braconidae, working as virulence gene vectors, and allowing the development of wasp larvae within hosts. These viruses are composed of multiple DNA circles that are packaged into infective particles, and injected together with wasp’s eggs during parasitization. One of the viral segments of Cotesia vestalis bracovirus contains a gene that has been previously described as a helicase of unknown origin. Here, we demonstrate that this gene is a Rep/Helicase from an intact Helitron transposable element that covers the viral segment almost entirely. We also provide evidence that this element underwent at least two horizontal transfers, which appear to have occurred consecutively: first from a Drosophila host ancestor to the genome of the parasitoid wasp C. vestalis and its bracovirus, and then from C. vestalis to a lepidopteran host (Bombyx mori). Our results reinforce the idea of parasitoid wasps as frequent agents of horizontal transfers in eukaryotes. Additionally, this Helitron-bracovirus segment is the first example of a transposable element that effectively became a whole viral circle.
„Graikijos Vėjas“ by Algirdas Landsbergis: Features of the Narrative and Intertext of the Myth
Authors: Adomavičienė Laimutė
Published: October 2017

The article analyses novella “Graikijos Vėjas” (1956) of the exile prose writer, playwright, literary and theatre critic Algirdas Landsbergis (1924–2004) by applying the narratological analysis and the theory of transtextuality. The article is based on Gérard Genette’s classical narratology and the theory of transtextuality and Irina Melnikova’s theory of intermediality. It is an innovative approach since it has not been applied for the selected text so far. The analysis of novella’s narrative, space and time (order, duration, frequency) and narrative mode has shown that there exists the relation between time and space in the text. Temporal succession of events (one extended day) is described by providing the story of earlier events in a chronological order. The narrative is twofold: on the one hand, it consists of the fixed internal focalisation, on the other hand of zero focalisation.The analysis of transtextual relation between the own and others’ texts has revealed the significance of the context of the Greek culture. The writer uses the heritage of European mythology creatively: he transforms the classical myth of Theseus by ironizing the plot, reminding the love story of Theseus and making a parody of heroes’ former features (strength, bravery, noble ambitions and actions).
“A Long Interior Journey” of Kate Brown as Border Crossing: Gender, Age, and Class in Doris Lessing’s “The Summer Before the Dark”
Authors: Miroshnychenko Lilia
Published: October 2017

The essay collection Doris Lessing: Border Crossings (2009), claims the writer’s persistent impulse to cross borders of all kinds – gender, maternity, class, ideology, geography, etc., and explores the impact it has on Lessing’s novels and autobiography. It therefore offers a new critical and theoretical approach that revises a traditional methodological paradigm of Lessing studies. This article extends the field of exploration by examining the transgressions of borders in the author’s novel of 1973 The Summer Before the Dark. Despite the extensive scholarship on the writer over the last years this novel remains among those which are less explored. However, it is relevant to the new theoretical scheme suggested by the authors of the volume. A central protagonist, Kate Brown, breaks restrictive gender and age codes as she is moving into “the darkness” of her new life order. The controversy of this move is announced in the title of the novel but towards its end the text suggests a transformation that enables the heroine to revise her agency inside and outside the domestic space, at the same time, through a set of narrative techniques and imagery, it problematises such a change.
Structure of Metacommunicative Comment and Folk Conceptions of Communication (based on Russian- and Belarusian-language internet forums of Belarus)
Authors: Bobko Tatyana
Published: October 2017

The article discusses the factors of speaker’s choice of additional metacommunication moves in non-institutional internet communication. The study is based on Russian- and Belarusian-language internet forums of Belarus, which allows to observe directly the metacommunicative reflection of speakers. The research has a comparative aspect and focuses on similarities and differences in verbalised metacommunication conceptions of Russian and Belarusian-speaking Belarusians, caused by the attitude to the language of communication: the language situation of Belarus, in which formally equilateral languages have in fact unequal conditions of functioning, actualises the symbolic use of the Belarusian language. It has been established that the choice of additional metacommunication moves with a particular function in Russian and Belarusian-speaking internet communication is determined by such factors as speakers’ representations about the communication norms and focus on certain communication aspects; for the Belarusian-language internet dialogue a special relation to the language, conditioned by its ethno-consolidating and symbolic functions, becomes relevant.
Academic Discourse in Polish Specialised Literature
Authors: Król-Kumor Martyna
Published: October 2017

The article is an attempt at reconstructing the concept of academic discourse based on the available Polish specialised literature.In result of analysis, it has turned out that the concept of academic discourse does not have a clear definition in Polish science yet and its name is often used as a synonym for scientific discourse and didactic discourse. The works dealing with academic discourse may generally refer to two areas of expertise: pedagogy and linguistics.The most significant research result of this article is coming up with the typology of academic discourse from pragmatic point of view. The following subtypes have been separated within academic discourse: scientific-academic discourse, didactic-academic discourse, educational-academic discourse, administrative-academic discourse and public-academic discourse. Each type of academic discourse has features which are common for all subtypes (they have the same place of discourse functioning and strict connection between discourse participants and an academic institution) as well as differentiating features, among which there is a purpose of activity within each subtype of academic discourse (purposes such as cognition, working out didactic methods, teaching, managing the university and creating a positive, favourable social image of the university).
Notes on Expression GUERRILLA WAR
Authors: Połowniak-Wawrzonek Dorota
Published: October 2017

The word combination guerrilla war has a terminological meaning ‘war, during which the weaker side uses the tactics of avoiding general battles and combats unexpected enemy attacks with the help of small military units or partisans’. The combination guerrilla war is associated by users of common language primarily with semantic elements such as ‘a scope of insidious, hidden and difficult to predict, tiring opponent actions’. In the modern texts, the term guerrilla war can undergo a metaphorisation process – it is a determinologisation of multiword expression of military terms. In the figurative sense of the verbal connection guerrilla war there are characterised semantic elements as ‘set of insidious actions, hidden, difficult to predict, directed against to someone or to something, to achieve something, teasing the opposite side, her fatigue, limiting its influence’. In some texts determinologisation signals were presented – a change of component pattern, clauses appeared, which indicates metaphorisation of compound, for example: tax guerrilla war, office guerrilla war. The texts which reported metaphored military term guerrilla war featured the following metaphors: POLITICS is a WAR, ECONOMIC PERFORMANCE is a WAR, DIFFERENT, SPECIAL ACTIVITIES and FORMS OF COMPETITION is a WAR.

O risco de parcerias público-privadas em saúde pública pode ser classificado?
Authors: Silva Vera Luiza da Costa e , Turci Silvana Rubano Barretto , Oliveira Ana Paula Natividade de , Richter Ana Paula
Published: October 2017

Resumo: Durante os próximos anos, Parcerias Público-Privadas (PPP) deverão desempenhar um papel cada vez mais relevante, despontando como uma importante alternativa de financiamento de projetos e de infraestrutura no cenário de serviços públicos. No entanto, especialmente para a Saúde Pública, as PPP nem sempre são uma boa alternativa, uma vez que pode haver distorção da agenda que define as necessidades da saúde, favorecendo os interesses das empresas. Os órgãos públicos podem se beneficiar da colaboração com o setor privado em áreas em que há falta de especialização, tais como desenvolvimento de pesquisas e tecnologias. Mesmo nesses casos, os papéis de cada instituição devem ser bem definidos, para que não haja conflito de interesses. Isso pode ser um desafio quando se trata da formulação de políticas públicas e regulatórias, sobre os impactos que determinadas políticas possam exercer, especialmente sobre nações em desenvolvimento. Envolver-se com o setor privado, sem comprometer a integridade das ações governamentais, exige ampla discussão por parte dos atores da saúde pública, por motivos claros de conflito das visões e escopos entre corporações e saúde pública. Alia-se a isso a necessidade de abordagens multissetoriais, alta carga de investimentos financeiros das várias dimensões das políticas de controle de doenças mais prevalentes, sobretudo as doenças crônicas não transmissíveis (DCNT). Este artigo classifica as PPP em categorias, a fim de minimizar os riscos potenciais de conflito de interesses que podem ter impacto na saúde pública. Essas categorias são definidas como possíveis, possíveis com ressalvas e impossíveis de se envolver com determinadas instituições.

RESUMO A partir do exame dos processos multifacetados de elaboração de artigos científicos durante uma experiência didática desenvolvida na disciplina de Pesquisa Aplicada ao Ensino de Língua Portuguesa (PAELP) do curso de Letras da Universidade Federal da Paraíba, este trabalho visa descrever o artigo científico como gênero caleidoscópico. Analisamos os textos elaborados no decorrer da disciplina, por meio dos aportes teóricos e metodológicos do Interacionismo Sociodiscursivo (cf.: Bronckart 1999, 2006, 2008; Bulea 2010; Schneuwly e Dolz 2004), que, também, alicerçaram os procedimentos didáticos. Os dados gerados indicam a necessidade de ampliação das definições existentes sobre o gênero artigo científico e o papel decisivo das microações de linguagem nas estratégias de didatização do gênero artigo científico.
Um estudo do gênero abstract na disciplina de Antropologia: a heterogeneidade da(s) área(s)
Authors: GIL Beatriz , ARANHA Solange
Published: October 2017

RESUMO Este artigo analisa a constituição do gênero abstract de artigos de pesquisa em suas características retóricas e linguísticas na disciplina de Antropologia em um corpus de 24 abstracts, retirados de dois periódicos Qualis A1. O modelo de movimentos retóricos proposto por Gil (2011) e os conceitos de stance, hedges e boosters (cf.: Hyland 1998, 2002, 2011) foram usados. Mesmo sendo da mesma área, os periódicos são frutos de fazeres de pesquisa múltiplos, ou seja, as disciplinas e as fronteiras ocupadas pelas pesquisas são determinantes na constituição desses gêneros, o que corrobora a noção de tipificação (cf.: Bazerman 2006, 2009).
Recontextualização e sedimentação do discurso e da prática social: como a mídia constrói uma representação negativa para o professor e para a escola pública
Authors: FIGUEIREDO Débora de Carvalho , BONINI Adair
Published: October 2017

RESUMO O tema abordado nesse artigo é a representação do professor produzida pela mídia brasileira e o modo como essa representação, através da recontextualização da docência em diversos gêneros, se sedimenta na sociedade, inclusive na escola e no discurso do próprio professor. Como referencial teórico, adotamos a vertente da Análise Crítica do Gênero proposta em Bonini (2013), que toma por base a perspectiva crítica proposta pela Análise Crítica do Discurso (Fairclough 1992, 2003), acrescida de uma teoria de gênero. Nessa linha, discutimos como a prática social da docência (e seu agente principal, o professor) é recontextualizada de forma negativa em gêneros da mídia jornalística (notícia e reportagem) e em gêneros de outras mídias (charge, meme, vídeo, postagem de blog, página do Facebook).

Published: October 2017

RESUMO Este estudo teve por objetivo analisar evidências psicométricas de validade e confiabilidade da Escala de Motivação Docente (EMD), que visa explorar a motivação autodeterminada de professores. A EMD foi desenvolvida fundamentando-se nos pressupostos da Self-Determination Theory (SDT), que aborda a motivação autodeterminada como um processo intrínseco, sujeita a influências sociocontextuais a partir das necessidades psicológicas básicas de autonomia, competência e pertencimento. Após a análise de conteúdo e da semântica dos itens e o teste piloto, a versão preliminar da EMD foi aplicada em 398 professores universitários brasileiros. Os resultados exploratórios levaram ao refinamento da EMD, ficando a versão final composta por 24 itens, pontuados em uma escala do tipo Likert, distribuídos em cinco dimensões: Performance, Desenvolvimento, Prática Docente, Formação Continuada e Inserção Institucional. A análise fatorial confirmatória evidenciou índices de ajustes adequados, confirmando o modelo estrutural proposto. Ainda que incipientes, esses resultados são consistentes para evidenciar a validade de construto da EMD, apontando perspectivas para a sua utilização em avaliação motivacional docente. Recomenda-se, contudo, a continuidade de estudos de validação que corroborem com os atuais achados e os ampliem.
Inovação pedagógica universitária mediada pelo Facebook e YouTube: uma experiência de ensino-aprendizagem direcionado à geração-Z

Published: October 2017

RESUMO A educação superior tem encontrado grandes desafios em função das velozes transformações da sociedade e, neste sentido, a aplicação de métodos pedagógicos inovadores que estimulem os alunos a criar e a desenvolver o espírito científico e reflexivo é constantemente requisitada. Entretanto, primeiramente, deve-se considerar a utilização de estratégias de aproximação com os estudantes, especialmente com os mais jovens, nascidos a partir de meados da década de 1990, que estão, atualmente, ingressando nas universidades. Para este grupo de estudantes, denominado de Geração Z, é essencial que os educadores renovem seus métodos de ensino para melhorar o processo de aprendizagem. Neste estudo, é avaliado se a utilização de tecnologias virtuais como Facebook e YouTube apresenta bons resultados no processo de ensino-aprendizagem de estudantes de uma universidade de Salvador. O Facebook foi utilizado como principal canal de comunicação entre professor e alunos; o YouTube, como um canal para compartilhamento de videoaulas desenvolvidas pelos próprios estudantes. Ambas as propostas foram sugeridas e não impostas aos estudantes. Ao final foi aplicado um questionário semiestruturado para avaliar a percepção discente. Verificou-se um alto grau de participação dos estudantes nas atividades propostas. Além disso, a percepção deles de que tais atividades foram eficazes para a construção do conhecimento foi o principal indicador positivo da análise, o que permitiu inferir que o uso dessas tecnologias é eficaz no processo de aprendizado dos estudantes, especialmente dos mais jovens.
Conferências Nacionais de Educação: intelectuais, Estado e discurso educacional (1927-1967)
Authors: Vieira Carlos Eduardo
Published: October 2017

RESUMO O presente artigo tem como objeto o discurso educacional enunciado ao longo das treze Conferências Nacionais de Educação (CNEs), organizadas pela Associação Brasileira de Educação (ABE) e realizadas entre 1927 e 1967. Em termos metodológicos, assumimos os pressupostos do contextualismo linguístico, em especial, a noção de linguagem complexa. Privilegiaremos a caracterização da ABE e dos seus eventos, as relações da ABE com o Estado, assim como formularemos uma hipótese sobre a estruturação do discurso educacional. O corpus documental da pesquisa é composto de documentos de natureza diversificada, tais como atas, correspondências, notícias veiculadas em jornais, conferências e moções apresentadas durante as CNEs. No estudo realizado, pudemos identificar a ABE e as CNEs como lugares privilegiados para projetar uma intelligentsia autorizada a falar sobre os problemas e, sobretudo, sobre as metas e as prioridades da educação nacional. O estudo das CNEs revelou, também, que os congressos educacionais cumpriram múltiplas funções, entre as quais destacamos: dar visibilidade às ações do Estado; legitimar os intelectuais envolvidos com a direção das reformas educacionais; conquistar o consentimento da sociedade em geral e da comunidade escolar em particular para a implementação das mudanças pretendidas; e, por fim, estruturar o discurso educacional, que pretendia a organização nacional a partir da reforma da cultura e da escola.
When noise became information: State-of-the-art in biospeckle laser
Authors: Braga Júnior Roberto Alves
Published: October 2017

ABSTRACT Laser was presented to science and industry in the 1960s and shortly became a useful tool in many areas, with applications based on its multiple characteristics such as coherence of light, which presents a phenomenon known as interference pattern, or speckle, when beam returns from an illuminated surface. Despite great application of speckle pattern, its residual presence, for example, in interferometric approaches was considered as a noise, demanding filtering. However, grains themselves became information as their dynamic changes in time started to be linked to biological sample activity. Dynamic laser speckle has been since then a phenomenon widely used to monitor biological activities in many areas from agriculture to medicine. It is known as biospeckle laser (BSL) when adopted in biological material, with high sensitivity to follow very tiny movements in biological tissues, linked to changes in speckle provided by scatterer activities inside and outside cells. Since the 1970s, biospeckle laser usage follows a crescent technologic spiral where technological developments opened room for new applications, while new demands regarding biological monitoring forced the development of new methodologies. Therefore, potential adoption of the phenomenon as a sensor, for instance, in agricultural and medical processes, as well as constant offer of new devices provided new turns in the BSL technologic spiral and opened room for technique improvement. In this study, I present a short history of biospeckle laser (BSL) with applications and development associated with challenges regarding its usage in portable and accessible devices or even in commercial equipment. And the history was packed in a temporal diagram identifying the breakpoints responsible for improvements in the use of the technique.
UM PASSARINHO NA MÃO OU DOIS VOANDO? DILEMAS DO GRUPO CARTEIRO AMIGO ENTRE SE EXPANDIR ORGANICAMENTE NA FAVELA DA ROCINHA OU SE ARRISCAR PARA ALÉM DA ZONA DE CONFORTO

RESUMO O presente estudo está situado na Rocinha, a maior favela da América Latina. Durante os primeiros anos da década de 2000, nessa tradicional comunidade carioca, além dos problemas de ordem social e econômica – como trafico de drogas, violência urbana e saneamento básico – seus moradores não eram assistidos com serviços públicos básicos como a entregade correspondências pelos Correios, tanto pela violência, quanto em virtude da ausência de padronização de endereços em suas ruas e vielas. Nesse contexto, três empreendedores observam uma oportunidade e deixam seus empregos para criarem o Grupo Carteiro Amigo (GCA), uma iniciativa que transformou a realidade da comunidade. O artigo apresenta um breve histórico da empresa e, em especial, aborda o dilema do crescimento organizacional, refletindo sobre os desafios e oportunidades de aumentar a base de clientes na Rocinha ou de franquear o negócio para outras favelas do Rio de Janeiro e do Brasil.

Resumo Objetivo Avaliar os indicadores relacionados à oferta de exames citopatológicos do colo do útero, sua qualidade, frequência de alterações celulares e seguimento informado de lesões de alto grau, em Minas Gerais e suas macrorregiões de saúde. Métodos Estudo descritivo com base em dados do Sistema de Informação do Câncer do Colo do Útero (SISCOLO), de 2006 a 2011. Resultados A razão de exames citopatológicos do colo do útero em mulheres de 25 a 59 anos manteve-se estável, porém sem alcançar a meta estadual pactuada. Aproximadamente 75% dos exames foram realizados na população-alvo e houve progressiva redução na proporção de citopatológicos do colo do útero sem citologia anterior. Em média, 51,2% dos exames foram realizados no período de até um ano. Quanto à qualidade do exame, destaca-se o índice de positividade, categorizado como baixo durante todo o período analisado. Observou-se baixo percentual de seguimento informado no estado. Conclusão Os resultados evidenciam a necessidade de aprimoramento do programa de rastreamento em relação à oferta e qualidade do exame, bem como ao direcionamento correto quanto à faixa etária e à periodicidade, visando garantir o acesso da população-alvo e o encaminhamento para a investigação diagnóstica e tratamento das lesões precursoras, quando indicado.

Published: October 2017

Resume Objective: to translate and validate to Spanish the Caring Assessment Scale tool, CAT-V, by Joanne Duffy, within the framework of Jean Watson; as a secondary objective, it is proposed to evaluate its psychometric properties. There are tools designed to measure the patient’s perception of provided cares, including CAT-V, the subject of our interest, in a way that it can be used in Spanish-speaking patients. Methods: to meet the objectives, it was performed sequential translation and retro-translation of the scale to be validated, through a standardized procedure. The final version of that scale was validated in a sample of 349 patients from four public and two private hospitals in Madrid, Spain. Results: The instrument was translated and validated with high internal consistency (Cronbach’s alpha .953). The subsequent factor analysis revealed a three-factor structure, not coincident with the data from the US population. Conclusion: it is considered that the translation of CAT-V is a suitable instrument to be used in the evaluation of patient care in Ibero-american health centers whose language is Spanish.
