Using affective brain-computer interfaces to characterize human influential factors for speech quality-of-experience perception modelling
Authors: Gupta Rishabh , Laghari Khalil , Banville Hubert , Falk Tiago H.
Published: April 2016

As new speech technologies emerge, telecommunication service providers have to provide superior user experience in order to remain competitive. To this end, quality-of-experience (QoE) perception modelling and measurement has become a key priority. QoE models rely on three influence factors: technological, contextual and human. Existing solutions have typically relied on the former two and human influence factors (HIFs) have been mostly neglected due to difficulty in measuring them. In this paper, we show that measuring human affective states is important for QoE measurement and propose the use of affective brain-computer interfaces (aBCIs) for objective measurement of perceived QoE for two emerging speech technologies, namely far-field hands-free communications and text-to-speech systems. When incorporating subjectively-derived HIFs into the QoE model, gains of up to 26.3 % could be found relative to utilizing only technological factors. When utilizing HIFs derived from an electroencephalography (EEG) based aBCI, in turn, gains of up to 14.5 % were observed. These findings show the importance of using aBCIs in QoE measurement and also highlight that further improvement may be warranted once improved affective state correlates are found from EEGs and/or other neurophysiological modalities.
Lateral Load Behavior of an Open-Ground-Story RC Building with AAC Infills in Upper Stories
Authors: Bose Supratik , Rai Durgesh C.
Published: April 2016

Autoclaved aerated concrete (AAC) masonry infills in upper stories can be beneficial for improving the seismic response of open-ground-story (OGS), reinforced concrete (RC)–frame buildings. Two reduced 1:2.5-scale models of single-story, single-bay RC frames with and without AAC infill masonry were tested for resistance properties and hysteretic behavior. Low strength and stiffness of AAC masonry, about half of the conventional brick masonry, led to improved load sharing between the infill and the frame, which helped an early development of frame yield mechanism for enhanced energy dissipation. Test results were used to evaluate the reliability of using existing strength and stiffness relations of conventional masonry infilled RC frames for AAC infilled frames. Analytical models were developed to predict the observed hysteretic behavior of tested specimens. Nonlinear analyses of a five-story, four-bay OGS-RC frame were performed for conventional brick masonry infills and relatively softer and weaker AAC infills in upper stories. The results indicated that the undesirable effect of weak/soft ground story mechanism of OGS-RC frames can be reduced to an acceptable level by using AAC infills in upper stories.
Invasive Narratives and the Inverse of Slow Violence: Alien Species in Science and Society
Authors: Lidström Susanna , West Simon , Katzschner Tania , Pérez-Ramos M. Isabel , Twidle Hedley
Published: April 2016

Environmental narratives have become an increasingly important area of study in the environmental humanities. Rob Nixon has drawn attention to the difficulties of representing the complex processes of environmental change that inflict ‘slow violence’ on vulnerable human (and non-human) populations. Nixon argues that a lack of “arresting stories, images and symbols” reduces the visibility of gradual problems such as biodiversity loss, climate change and chemical pollution in cultural imaginations and on political agendas. We agree with Nixon that addressing this representational imbalance is an important mission for the environmental humanities. However, we argue that another aspect of the same imbalance, or representational bias, suggests the inverse of this is also needed—to unpack the ways that complicated and multifaceted environmental phenomena can be reduced to fast, simple, evocative, invasive narratives that percolate through science, legislation, policy and civic action, and to examine how these narratives can drown out rather than open up possibilities for novel social-ecological engagements. In this article we demonstrate the idea of invasive narratives through a case study of the ‘invasive alien species' (IAS) narrative in South Africa. We suggest that IAS reduces complex webs of ecological, biological, economic, and cultural relations to a simple ‘good’ versus ‘bad’ battle between easily discernible ‘natural’ and ‘non-natural’ identities. We argue that this narrative obstructs the options available to citizens, land managers and policy-makers and prevents a more nuanced understanding of the dynamics and implications of biodiversity change, in South Africa and beyond.
Mathematizing Nature's Messiness: Graphical Representations of Variation in Ecology, 1930-Present
Authors: Martin Laura J.
Published: April 2016

This article explores the rise of the line graph and an associated statistical method, linear regression, in ecology. At the turn of the 20th century, many ecologists studied variation in organismal traits, like height and weight, among populations of a species. The statistical practice of “polygons of variation” emerged out of such studies. But between 1930 and 1950, polygons of variation were gradually eclipsed by line graphs. Motivated by the recent and disastrous Dust Bowl, American ecologists began to place organismal variables and environmental variables on the same graph. They began to use linear regression, a then-obscure statistical method first developed to study whether parents passed their morphological traits onto offspring, to interpret these graphs. This use of linear regression marked an important shift in how ecologists interpreted biological variation. Variation—once ecologists' object of study—was now noise. Yet ecologists did not abandon their commitment to the idea that nature is complex, various, and interconnected. Rather, they came to read biologically meaningful patterns in seemingly “messy” graphs, using linear regression differently than other scientists, even those in closely allied disciplines. I situate this analysis in a broad STS literature on modeling that has tended to analyze the decision to model, or the choice of variables to include in a model, rather than how practitioners interpret the models they choose. I contend that not only has ecologists' use of linear regression shaped understandings of nature, but ecologists' understandings of nature have also shaped their use of linear regression.
Thinking About Inheritance Through the Figure of the Anthropocene, from the Antipodes and in the Presence of Others
Authors: Instone Lesley , Taylor Affrica
Published: April 2016

Modes of thinking matter. In this article we engage with the figure of the Anthropocene as the impetus for rethinking the messy environmental legacies of Australian settler colonialism that we have inherited. We do this rethinking in a small rural valley community, where the intractable realities of human and more than human settler colonial relations are played out on a daily basis. We also try to do this rethinking collectively, in the presence of other animals with whom our inherited pasts, our mundane everyday presents and our uncertain futures are inextricably enmeshed. What comes of all this thinking is a common account of mutual multispecies vulnerabilities and of collective agencies that recasts the dominant tales of a singular Anthropocene and the conventional human-centred inheritances of a rural Australian place.
Unruly Raccoons and Troubled Educators: Nature/Culture Divides in a Childcare Centre
Authors: Pacini-Ketchabaw Veronica , Nxumalo Fikile
Published: April 2016

Current times of anthropogenically damaged landscapes call us to re-think human and nonhuman relations and consider multiple possibilities for alternative and more sustainable futures. As many environmental and Indigenous humanities scholars have noted, central to this re-thinking is unsettling the colonial nature/culture divide in Western epistemology. In this article, through a series of situated, small, everyday stories from childcare centres, we relate raccoon-child-educator encounters in order to consider how raccoons' repeated boundary-crossing and their apprehension as unruly subjects might reveal the impossibility of the nature/culture divide. We tell these stories, not to offer a final fixed solution to the asymmetrical, awkward and frictional entanglements of humans' and raccoons' lives, but as a responsive telling that may bring forth new possibilities for responsible, affective and ethical co-habitations.
Raven, Dog, Human: Inhuman Colonialism and Unsettling Cosmologies
Authors: Zahara Alexander R. D. , Hird Myra J.
Published: April 2016

As capitalism's unintended, and often unacknowledged, fallout, humans have developed sophisticated technologies to squirrel away our discards: waste is buried, burned, gasified, thrown into the ocean, and otherwise kept out-of-sight and out-of-mind. Some inhuman animals seek out and uncover our wastes. These ‘trash animals' choke on, eat, defecate, are contaminated with, play games with, have sex on, and otherwise live out their lives on and in our formal and informal dumpsites. In southern Canada's sanitary landfills, waste management typically adopts a ‘zero tolerance’ approach to trash animals. These culturally sanctioned (and publicly funded) facilities practice diverse methods of ‘vermin control.’ By contrast, within Inuit communities of the Eastern Canadian Arctic, ravens eat, play, and rest on open dumps by the thousands. In this article, we explore the ways in which western and Inuit cosmologies differentially inform particular relationships with the inhuman, and ‘trash animals' in particular. We argue that waste and wasting exist within a complex set of historically embedded and contemporaneously contested neo-colonial structures and processes. Canada's North, we argue, is a site where differing cosmologies variously collide, intertwine, operate in parallel, or speak past each other in ways that often marginalize Inuit and other indigenous ways of knowing and being. Inheriting waste is more than just a relay of potentially indestructible waste materials from past to present to future: through waste, we bequeath a set of politically, historically, and materially constituted relations, structures, norms, and practices with which future generations must engage.
Resposta emocional à publicidade em mídias sociais
Authors: Hahn Ivanete Schneider , Scherer Flavia Luciane , Oliveira Maria Carolina Serpa Fagundes De , Scheid Régis
Published: April 2016

Este estudo partiu da lacuna teórica de que as investigações sobre a publicidade em mídias sociais não costumam descrever as emoções dos consumidores sobre os anúncios. Deste modo, se propôs a descrever as respostas dos consumidores para anúncios reais expostos em duas comunidades de marca no Facebook: uma de marca icônica e a outra de uma marca local. Foram conduzidos dois levantamentos de campo, sendo que o primeiro ocorreu com 985 seguidores da marca icônica e o segundo com 233 consumidores da marca local. Os resultados permitem concluir que (1) o tipo de anúncio parece não influenciar diretamente o desejo de compra/consumo do produto; (2) a crença dos seguidores a respeito da marca afeta a reação emocional aos anúncios; (3) as características sociodemográficas (escolaridade e gênero) não se mostraram significantes na análise dos anúncios.
Formas de aprendizagem e saberes no trabalho de manicures
Authors: Gallon Shalimar , Bitencourt Betina Magalhães , Viana Daniela Dietz , Antonello Claudia Simone
Published: April 2016

As discussões a respeito da importância do trabalho são crescentes em nossa sociedade. Ela se mobiliza a fim de atender interesses econômicos, legitimando determinadas profissões como mais importantes. Com o objetivo de superar essa concepção, analisamos ofícios que contribuem para a sociedade, mas não possuem o mesmo valor social percebido. Estudamos o conhecimento adquirido no exercício de determinado trabalho e como ocorre a aprendizagem por meio das práticas, baseados na ideia que todo tipo de ação produz conhecimento. A investigação para o presente estudo desenvolveu-se em dois salões de beleza, na cidade de Porto Alegre (RS), nos quais trabalham sete manicures, no total. O estudo foi realizado por meio de observação não participante e de entrevistas não estruturadas, no período de dezembro de 2011 a março de 2012. Identificou-se que as profissionais adaptam a maioria das técnicas ensinadas no curso de manicure. Isso significa que cada indivíduo tem seu jeito de exercer o próprio trabalho, não havendo uma única maneira certa de realizá-lo. O jeito de cada manicure desempenhar suas atividades só é descoberto na prática, quando ela aplica seu conhecimento. Tal processo produz novo conhecimento e nova prática, uma vez que as ações tanto são sustentadas pela prática como a constituem.

Além disso, essas empresas encontram dificuldades para alinhar as estratégias de inovação e suas práticas organizacionais. O artigo contribui de forma prática, ao destacar as dificuldades que essas empresas enfrentam para gerir seus processos de inovação, e de forma teórica, pela apresentação de um modelo de diagnóstico de inovação.
Do TOC para manufatura enxuta: um estudo de caso de mudança de gestão da produção
Authors: Pinto Ricardo Aurélio Quinhões , Torres Júnior Alvair Silveira , Tortato Ubiratã
Published: April 2016

Esta pesquisa se deu em uma empresa que trocou a forma de gestão da produção de Teoria das Restrições (TOC) para manufatura enxuta – Sistema Toyota de Produção (STP) – como base para firmar sua vantagem competitiva. A empresa em análise, uma das líderes do segmento de metais sanitários, tem o baixo lead time de entrega dos seus produtos como objetivo estratégico de produção. Porém, para manter esse objetivo, enquanto usava a TOC, a empresa precisava se valer de altos volumes de estoques como forma de prevenir-se das incertezas do mercado e do processo. Com intuito de firmar sua vantagem competitiva e reduzir custos produtivos, a empresa decidiu-se por implantar o sistema de manufatura enxuta. Com a conclusão da pesquisa, constatou-se que fatores relacionados à “cesta” de elementos da manufatura enxuta estavam fortemente relacionados à robustidão da sua vantagem competitiva. Esta pesquisa é exploratória descritiva, formatada nos moldes de estudo de caso único.

Authors: Wegner Douglas , Begnis Heron Sérgio Moreira , Alievi Rejane Maria , Maehler Alisson Eduardo
Published: April 2016

A dinâmica das redes interorganizacionais (RIOs) permanece pouco estudada na teoria organizacional e com limitadas contribuições à prática gerencial. Este estudo tem o objetivo de revisar a teoria sobre o ciclo de vida de RIOs e propor um modelo ajustado às características das redes de pequenas empresas. A partir da revisão teórica e entrevistas com especialistas, foi gerado um modelo preliminar e foram identificadas sete dimensões de análise. Como resultado, o artigo apresenta um modelo de ciclo de vida de RIOs composto por seis fases e suas respectivas descrições: Concepção, Nascimento & Formalização, Desenvolvimento, Consolidação & Maturidade, Declínio e Dissolução. A existência de períodos de transformação ou reestruturação é apontada como necessária para que as redes se mantenham atrativas ao longo do tempo ou consigam reverter uma tendência de declínio.
Como a gestão das redes estratégicas regionais afeta os ganhos proporcionados às pequenas empresas associadas
Authors: Verschoore Jorge Renato , Klanovicz Cristiano , Durayski Juliana , Vieira Leonidas
Published: April 2016

A trajetória dos estudos brasileiros sobre a cooperação em redes evidenciou a íntima relação entre a gestão e os resultados das iniciativas. Essa evolução motivou a realização deste estudo, que objetiva compreender como a gestão de redes estratégicas regionais (RERs) afeta os ganhos proporcionados às pequenas empresas associadas. Para tanto, realizou-se uma pesquisa exploratória quantitativa baseada em uma survey com 150 entrevistas em cinquenta RERs. Os resultados apontam que as RERs proporcionam ganhos às empresas envolvidas. Evidenciou-se que ganhos como aprendizagem, inovação e poder de mercado são mais intensos em RERs com um nível avançado de gestão e, também, que o ganho das relações de interação é proporcionado em intensidade similar tanto por RERs avançadas quanto por redes intermediárias e básicas. Por fim, os resultados indicaram como as ferramentas de gestão afetam positivamente os ganhos proporcionados pelas RERs, originando proposições de implicações práticas da adoção dessas ferramentas.

Authors: Begnini Sérgio , Almeida Lirane Elise Defante Ferreto de
Published: April 2016

A concepção de desenvolvimento rural está em plena construção, havendo consenso de que é multidimensional. Nesse sentido a identificação de graus de desenvolvimento pode revelar determinados fenômenos, auxiliando nas tomadas de decisões e formulação de políticas públicas que contribuam para a melhoria na qualidade de vida. O objetivo desta pesquisa foi analisar o desenvolvimento rural do estado de Santa Catarina, calculando o grau de desenvolvimento rural, considerando 293 municípios. O estado de Santa Catarina aparece como heterogêneo, pois 47,78% dos municípios ficaram classificados com grau de desenvolvimento rural acima ou igual à média, e 52,22% ficaram abaixo da média. Cada mesorregião apresentou um agrupamento de municípios com variados graus de desenvolvimento rural, e a maior parte ficou classificada nos graus médio, baixo e alto. Conclui-se que entre as regiões existem padrões de desenvolvimento divergentes, sendo possível identificar aglomerações geográficas de acordo com o grau de desenvolvimento rural.

Media Inc.: Consolidated Television, Tele-King and investment diversification by organized crime
Authors: Barnett Vincent L.
Published: April 2016

This article documents the involvement of leading members of American organized crime, specifically the East Coast Syndicate lead by Meyer Lansky and Frank Costello, with some US media industries in the 1940s and 1950s. It does so by tracing the creation, ownership and business history of two television-manufacturing companies, Consolidated Television Incorporated and the Tele-King Corporation, which it has been alleged were controlled by Syndicate interests. It uses various forms of primary and secondary sources to do this, such as FBI files, witness testimony and published accounts. It also examines the types of media products that these companies manufactured, why Syndicate members ventured into this investment sector, and how Syndicate control was initially exerted, maintained, and then exposed.
‘A Revolutionary Voice’: Analysing Maxine Peake’s Northern stardom in Silk and Room at the Top
Authors: Gorton Kristyn , Peirse Alison
Published: April 2016

This article explores how Maxine Peake’s explicit and directly articulated social conscience – specifically in terms of class, gender and Northernness – can be explored in television drama, and what this might say about her ‘Northern Stardom’ in our contemporary cultural climate. Our central case studies are the series Silk (2011–2014) and mini-series Room at the Top (2012), both chosen as recent productions that explicitly engage with politics but in quite different ways. In the case of Silk this is foregrounded as a courtroom drama, while Room at the Top’s 1950s’ setting demonstrates the way working-class men and women were able to break free of expectations around their gender and social standing – but at a cost. Peake is presented in popular culture as a rarity, a socially aware, politically active Northern actor who is able to break free of a Northern stereotype; at the same time, we will argue, as an actor she brings an honesty/emotion to the roles she plays that both chime with audience expectations of the ‘strong’ Northern woman and yet allow her to expose the fragility and anxiety inherent to this persona.
‘The Bake Off beefcake with the best buns in the business’: Sex, pies and Paul Hollywood
Authors: Jamieson Gill
Published: April 2016

As one of the judges on the hugely successful BBC series The Great British Bake Off (2010–), Paul Hollywood has become a food icon in the United Kingdom. Like other celebrity chefs, he has augmented an appreciation for careful food preparation and enhanced taste experiences, resisting the widespread consumer desire for easily accessible convenience food. This article explores Hollywood’s persona and the extent to which personality attributions associated with a ‘Northern’ identity paradigm are an intrinsic part of his appeal. I argue that Hollywood is selling more than cakes, pies, pastries and fancy bread through his various endeavours both on-and off-screen: he is selling an idea of the North as a place which values hard work, frugality and resourcefulness. For all the posturing about ‘food porn’ in the press, Hollywood’s work often celebrates the simplicity of comfort food, or the staples that define the routines of home cooking where repetition and familiarity are key aspects of the experience. Despite his success in the United Kingdom, Hollywood failed to emulate that success in the United States when he co-hosted The American Baking Competition (2013). This begs the question: what is it about a television star like Hollywood that makes his commodity value appeal and resonate in one market but ultimately sink without trace in the international market? Might we consider Hollywood as a case study in the limits of the transnational celebrity?

Published: April 2016

A cenoura é a quarta hortaliça mais consumida no país e uma das mais consumidas no mundo. Com o objetivo de avaliar o desempenho produtivo da cenoura em diferentes espaçamentos de plantio conduziu-se um experimento no período de outubro de 2013 a fevereiro de 2014. Utilizou-se o delineamento de blocos ao acaso em esquema fatorial 2 x 4, consistindo em dois espaçamentos entre linhas (20 e 25 cm) e quatro espaçamentos entre plantas (4, 6, 8 e 10 cm) com três repetições e utilizando a cultivar Brasília. A altura das plantas oscilou de 52,1 a 53,3 cm para os espaçamentos entre linhas e de 51,0 a 53,2 cm nos espaçamentos entre plantas, não se verificando diferenças significativas. Produtividade comercial de raízes superior foi obtida para o espaçamento de 20 cm entre linhas (40,6 t ha-1), em comparação ao espaçamento de 25 cm entre linhas (35,4 t ha-1). O espaçamento 4 cm entre plantas linhas apresentou maior rendimento de raízes comerciais (44,5 t ha-1). Maior massa fresca de raízes foi observada nos maiores espaçamentos entre linhas e plantas. À medida que se aumentou a população de plantas houve um acréscimo no percentual de raízes de maior comprimento e redução percentual de raízes mais curtas.

Este artigo apresenta resultados de um experimento de campo realizado para avaliar a resposta morfológica de uma praia arenosa durante um evento de ressaca do mar. O estudo foi realizado na Praia do Icaraí, localizada no litoral da Região Metropolitana de Fortaleza. O experimento de campo foi baseado no acompanhamento contínuo de cinco seções de controle a partir de informações topográficas e oceanográficas. Foram realizadas 7 campanhas de campo (28/01/14 a 09/02/14). As respostas morfológicas dos trechos observados foram diferentes em termos de erosão e deposição. A seção limitada por dunas antropizadas (S1) apresentou erosão da berma e da praia submersa. Os trechos costeiros limitados por uma estrutura de proteção costeira (S2 a S4) apresentaram recuo da parte superior do perfil. No trecho de dunas frontais (S5), houve uma erosão generalizada da duna e da berma. De forma geral, a Praia do Icaraí é vulnerável a eventos de ressaca do mar.

Prädiktions- oder Simulationsgüte sind nicht zwangsläufig die relevanten Eigenschaften für Modelle, die zur Reglersynthese verwendet
werden sollen. Eine regelungsorientierte Modellerstellung aus Messdaten wird mit dem Begriff ,,Identification for Control“
bezeichnet, wobei die bekannten Methoden für lineare Modelle und Regler entwickelt wurden. Eine nichtlineare Erweiterung ist dabei
nicht ohne weiteres möglich. Lokal lineare/affine Multi-Modell-Ansätze lassen es jedoch zu, Teile der linearen Theorie approximativ
auf nichtlineare Systeme anzuwenden. Dieser Beitrag stellt ein TS-Reglerentwurfsverfahren vor, das die lokalen Driftterme der
Teilmodelle näherungsweise kompensiert, um einen an der linearen Theorie orientierten lokalen Entwurf zu ermöglichen. Des Weiteren
wird ein iterativer Entwurf auf Basis von im geschlossenen Regelkreis identifizierten TS-Modellen vorgestellt. Die Methoden werden in
zwei Simulationsfallstudien (Fahrzeuglängsdynamik und Drei-Tank-System) demonstriert.

Zur Wiederherstellung der Bewegungsfähigkeit, beispielsweise nach Verletzungen des Rückenmarks, werden bei der Rehabilitation verstärkt
Therapieroboter eingesetzt. In diesem Beitrag wird die Regelung eines Gangrehabilitationsroboter mittels adaptiver Folgereglung
vorgestellt. Ziel ist die Einregelung einer Gangtrajektorie unabhängig von den Einflüssen des Patienten durch die zusätzliche Masse
oder aufgebrachte Kräfte beim Training. Darüber hinaus treten dominante, variierende Reibungseffekte in den Antrieben des Roboters
auf, die ebenfalls kompensiert werden müssen. Die Evaluation des Verfahrens anhand von Messungen an einem Prototyp des Roboters zeigt,
dass bereits nach kurzer Einschwingzeit der Adaption eine sehr gute Trajektorienfolge erzielt wird.

Segmentation and classification of bright lesions to diagnose diabetic retinopathy in retinal images
Authors: Santhi D. , Manimegalai D. , Parvathi S. , Karkuzhali S.
Published: April 2016

In view of predicting bright lesions such as hard exudates, cotton wool spots, and drusen in retinal images, three different segmentation techniques have been proposed and their effectiveness is compared with existing segmentation techniques. The benchmark images with annotations present in the structured analysis of the retina (STARE) database is considered for testing the proposed techniques. The proposed segmentation techniques such as region growing (RG), region growing with background correction (RGWBC), and adaptive region growing with background correction (ARGWBC) have been used, and the effectiveness of the algorithms is compared with existing fuzzy-based techniques. Images of eight categories of various annotations and 10 images in each category have been used to test the consistency of the proposed algorithms. Among the proposed techniques, ARGWBC has been identified to be the best method for segmenting the bright lesions based on its sensitivity, specificity, and accuracy. Fifteen different features are extracted from retinal images for the purpose of identification and classification of bright lesions. Feedforward backpropagation neural network (FFBPNN) and pattern recognition neural network (PRNN) are used for the classification of normal/abnormal images. Probabilistic neural network (PNN), radial basis exact fit (RBE), radial basis fewer neurons (RB), and FFBPNN are used for further bright lesion classification and achieve 100% accuracy.

Published: April 2016

Clinical translation denotes a focused and rapid process of transferring scientific knowledge into clinical practice and patient care. As a new model of innovation it has gained importance in the biomedical research in recent years. To identify the current state of clinical translation within the routines of hospital based research, we examine structures of the interdisciplinary research consortium BIOFABRICATION in Hannover (Germany) with regard to translational strategies. Moreover, we illustrate general requirements and infrastructural conditions, which are essential to establish a top-level translation center. Consequently, a translational training programme, standardized processes for documentation as well as a platform to support the communication between translational stakeholders were introduced. As an outlook the framework conditions will be evaluated on translational efficiency. The acquired knowledge will be a first step to develop a guideline for an optimized clinical translation of life science research results. It can be finally used as a role model for the planning and optimization of other translational centers.
Shielding Effectiveness Estimation by using Monopole-receiving Antenna and Comparison with Dipole Antenna
Authors: Nešić Nataša J. , Dončov Nebojša S.
Published: April 2016

In this paper, a numerical analysis of shielding properties of a protective metal enclosure has been performed by simulating a receiving antenna placed inside. Here, the main focus is put on the monopole antenna type. This antenna type is used in an experimental set-up to measure the shielding effectiveness (SE) of the enclosure as often as some other antennas such as dipole. Numerical model, based on the Transmission-Line Matrix (TLM) method, is applied to numerically investigate an impact this antenna might have on a detected level of electromagnetic (EM) field when it is used in the SE measurements. As in experiments, the estimation of SE of an enclosure in the numerical model is performed based on the current induced on the antenna, directly provided by a compact TLM wire model. The model accuracy is verified through a comparison with the experimental results from the literature. The analysis includes the monopole antenna with different radii and lengths, in order to consider changes in the resonant frequencies and the SE level of enclosure. Finally, the enclosure with either the monopole or the dipole is simulated in order to compare their influence on EM field distribution inside the enclosure.

Solid Inclusions in Au-nuggets, genesis and derivation from alkaline rocks of the Guli Massif, Northern Siberia
Authors: Dvorani Sami N.
Published: April 2016

A total of 112 Au-nuggets, collected from alluvial placer deposits of the Ingarinda River from the Guli massif, located in northem Siberia, Russia, were investigated. The Guli massif consists of a huge dunite-clinopyroxenite complex (the largest complex in the world), an alkaline to highly alkaline rock suite (melilite, nephelinite, ijolite) enveloping the dunite and carbonatite intrusions, associated with disseminated schlieren type chromitite and Au-Ag, Pt placer deposits. The nuggets are characterized by various sizes and shapes and show chemical compositions Au, Au-Ag and AuCu, typical for a derivate of carbon-atites and/or ultramafic complexes. A great variety of oxide, silicate, REE-minerals, carbonate and sulphide inclusions have been detected in the nuggets, which are identical in mineralogy and chemical composition to mineral constituents of the alkaline to highly alkaline rock suite surrounding the Guli dunite core complex thus, considered as the source for Au-nuggets.
Airing Dirty Laundry: Reforming the Anti-Money Laundering and Anti-Terrorism Financing Regime in Malaysia
Authors: Hamin Zaiton , Omar Normah , Wan Rosli Wan Rosalili
Published: April 2016

Dealing with money laundering has been one of the toughest struggles nations around the world, including Malaysia, have had to face. Prevalent international concerns over such crime have led to the establishment of international policies and standards by the Financial Action Task Force (FATF), which aimed at preventing and ultimately criminalising such crime within the national boundary. In accordance with such policies, Malaysia has introduced the Anti-Money Laundering Act in 2001 (AMLA) as a legal modality in governing such crime. It has been amended and renamed the AMLATFA in 2003 to include terrorism financing. Again, recently in late 2013, AMLATFA has been amended to keep up with changing standards and times. Within this legal landscape, this paper will highlight the instrumental and normative problems surrounding the said legislation. The authors contend that despite the adherence to global governance standards, legal deficiencies in the AML/ATF law in Malaysia remained, which merits urgent attention and action from the relevant authorities. This paper employs a doctrinal legal research and secondary data of which the AMLATFA is the primary source. The secondary sources for this article include decided cases, articles in academic journals, books and online databases.

Efficient green synthesis of monomethine cyanines via grinding under solvent-free conditions
Authors: Eissa Fayez M. , Abdel Hameed Reda S.
Published: April 2016

A solvent-free, efficient, and green approach for the synthesis of monomethine cyanine dyes was carried out via grinding at room temperature in the presence of a minimum amount of catalyst. This green methodology aims to overcome the limitations and drawbacks of previously reported methods such as heating at high temperatures, use of large amounts of catalysts, use of solvents, modest yields, and long reaction times. Moreover, the advantages of the process include mild conditions with excellent conversion, and inexpensive procedure. The new synthetic method was demonstrated for eight reported dyes, as representatives, and showed high applicability for their analogues in the same way. The green context of the new methodology was noticeable, compared with the non-green components of the conventional one. The structure and purity of the resulting compounds were compared with the previously reported data and confirmed using thin layer chromatography, absorption spectra, elemental analysis, mass spectrometry, 1H-nuclear magnetic resonance (NMR) and 13C-NMR spectroscopy.
The anti-oxidant and pro-oxidant dichotomy of Bcl-2
Authors: Yee Yi Hui , Chong Stephen Jun Fei , Pervaiz Shazib
Published: April 2016

Across a wide spectrum of cellular redox status, there emerges a dichotomy of responses in terms of cell survival/proliferation and cell death. Of note, there is emerging evidence that the anti-apoptotic protein, Bcl-2, in addition to its conventional activity of titrating the pro-apoptotic effects of proteins such as Bax and Bak at the mitochondria, also impacts cell fate decisions via modulating cellular redox metabolism. In this regard, both pro- and anti-oxidant effects of Bcl-2 overexpression have been described under different conditions and cellular contexts. In this short review, we attempt to analyze existing observations and present a probable explanation for the seemingly conflicting redox regulating activity of Bcl-2 from the standpoint of its pro-survival function. The consequential effect(s) of the dual redox functions of Bcl-2 are also discussed, particularly from the viewpoint of developing novel therapeutic strategies against cancers rendered refractory due to the aberrant expression of Bcl-2.
Slovak healthcare workers’ lived experience of conscience
Authors: Blaho Radoslav
Published: April 2016

This paper investigates the meaning of conscience in providing healthcare and Slovak healthcare workers’ lived experience of conscience. It draws on data from semi-structured interviews with eleven healthcare professionals. The data was analyzed using a phenomenological hermeneutic interpretation. Two main themes relating to the lived experience of conscience were derived—preserving one’s conscience integrity, by satisfying one’s conscience in order to sustain it, using defense mechanisms for protection, following one’s inner conviction, and respecting the patient’s individuality and having a troubled conscience in relation to external factors, medical procedures and options, and demands by the authorities. The results are discussed in relation to the literature.
Prevalence of lesbian, gay, bisexual, and transgender among Japanese university students: a single institution survey
Authors: Ikuta Nasa , Koike Yuji , Aoyagi Naoko , Matsuzaka Akira , Fuse-Nagase Yasuko , Kogawa Kazuhiro , Takizawa Toshiyuki
Published: April 2016

Objective:

To elucidate the prevalence of lesbian, gay, bisexual, and transgender (LGBT) among Japanese youth, we conducted a survey research that targeted university students.

Materials and methods:

Participants were first-year students (n=1597) at Ibaraki University, Japan (Phase 1 study) or second- to fourth-year students (n=944) at the university who were randomly preferred in the survey (Phase 2 study). Surveys measured gender identity and sexual orientation, partly using the gender identity scale (GIS).

Results:

The prevalence of LGBT youth among university students were 2.7%, 0.5%, 5.3%, and 0.8% (Phase 1 study) or 1.4% (Phase 2 study), respectively. The GIS scores of the transgender group were significantly lower than those of the female, male, and LGB groups (p<0.01).

Discussion:

This is the first to clarify the prevalence of LGBT among youth in Japan. It has been suggested that such individuals in Japan, as in other countries, are at risk for physical and mental health concerns, thereby necessitating social and medical intervention. Further investigation in these areas will be needed.

Published: April 2016

Objective:

To verify the effects of metabolic syndrome (MS) and its relation to insulin resistance (IR) in children and adolescents with overweight or obesity after 24 months of follow-up.

Design:

Studies of repeated measures from April 2009 to April 2012. For both measurements, the evaluations performed were anthropometry, MS diagnosis, fasting blood glucose, glucose homeostasis model assessment (HOMA-IR), and insulin level; at a second evaluation, glycated hemoglobin (HbA1c) was used as an additional indicator of glucose metabolism alterations. Logistic regression between syndrome persistence and its components with glucose metabolism alterations was performed for each of its indicators. The SPSS version 17.0 software (95% CI) was used.

Location:

Center for Childhood Obesity, Campina Grande, Brazil.

Subjects:

Children and adolescents (n=133), aged 2–18 years, with overweight or obesity.

Results:

There was a significant decrease in MS during the study period, with persistence of the syndrome in 17.3% of the individuals. The presence of at least one alteration in glucose metabolism occurred in 45.1% of children and adolescents. The systolic and diastolic blood pressure, and the average levels of HOMA-IR showed significant decrease at the end of 24 months (p<0.01), and an elevated waist circumference (WC) remained associated with IR (p<0.01).

Conclusion:

There was observed no relationship of IR or other indicator of glycemic disorders by persistence of MS. An elevated WC remained associated with IR after controlling for the effects of the following variables: gender, age group, and other MS components.
