    Full Text Available Este artículo presenta, a partir de una etnografía realizada en 1979, un análisis de los barrios de Catumbi y Selva da Pedra , en Río de Janeiro, como casos ilustrativos de una polaridad característica de las ciudades brasileñas y en particular de las regiones metropolitanas. La tradición urbana ibérica, predominante y reproducida en la arquitectura y el urbanismo de los barrios y suburbios más antiguos, constituye uno de los extremos del espectro. En el otro se ubican los modelos del modernismo, que tratan de compensar su falta de inercia histórico-cultural con una extraordinaria agresividad ideológica asentada en el cientificismo progresista, legado más permanente de nuestro siglo XIX. Así, el foco de esta investigación es la apropiación del espacio, un proceso que forma parte de la dimensión de lo vivido, de la experiencia cotidiana.O presente artigo apresenta parte da etnografia, realizada em 1979, através da articulação de dois casos -bairros de Catumbí e da Selva da Pedra , no Rio de Janeiro- ilustrativos de uma polaridade característica das cidades brasileiras, em particular nas regiões metropolitanas.

    Full Text Available O artigo analisa, por meio da descrição de uma pesquisa etnográfica de cinco anos em uma vizinhança de Paris, França, um tipo específico de situação estabelecida nas relações entre atores na vida pública de uma grande cidade, aquelas chamadas aqui de “disputas de cortesia”. Trata-se daquele momento em que pessoas que não se conhecem põem-se a discutir por conta de algum discurso em sinal de reprovação apresentado por uma das partes e, devido a uma polêmica em torno de uma demanda de cortesia, podem chegar ao enfrentamento. The article Courtesy disputes in urban space: When courtesy becomes violence analyses, by the description of a five-year ethnography in a French neighborhood, the “courtesy dispute”, a specific type of situation established on the relations between actors in a big city public life. “Courtesy dispute” refers to the moment when people who don’t know each other start an argument because of a criticism made by another part and, motivated by a demand for courtesy, may follow towards violence.

  4. CUANDO LA ESCUELA SE TRANSFORMA EN UN INFIERNO: ESTUDIO SOBRE LAS REPRESENTACIONES SOCIALES DE LA VIOLENCIA ESCOLAR EN UNA ESCUELA SECUNDARIA DE LA CIUDAD DE MEXICO

    2012-12-01

    Full Text Available La violencia en la escuela se ha constituido a los largo de los últimos años en México en un tema prioritario en las investigaciones sociales como asimismo en un tópico destacado en la agenda pública gubernamental debido al incremento de la inseguridad en el interior de los establecimientos educativos y en su entorno, al grado de crueldad que denotan las acciones violentas y sus consecuencias, originando una multiplicidad de estudios que amparados en marcos teóricos y disciplinarios diversos han permitido un análisis del tema desde la perspectiva educativa, social, política, psicológica y de la salud. No obstante, la limitada literatura disponible que escrute este problema social desde la mirada de las representaciones sociales hace que el presente escrito muestre el análisis de las narrativas que los actores de una escuela secundaria periférica de la ciudad de México tienen sobre la violencia escolar con la pretensión de conocer el contenido de las representaciones sociales. Para alcanzar este objetivo se tuvo en cuenta un diseño cualitativo en donde se destaca la utilización de la entrevista, la observación y la revisión documental como las técnicas que permiten la creación de los datos a partir de los testimonios ofrecidos por los actores escolares de una escuela secundaria técnica y la teoría fundamentada como el recurso para la reconstrucción analítica del contenido de las narrativas. La importancia de estudiar este tema radica en la necesidad de hacer visible los significados sociales que el sentido común le atribuye a este fenómeno para entender las prácticas agresivas que se suscitan en el interior de la escuela además de brindar insumos que ayuden a una revisión de las políticas públicas que se implementan actualmente para la creación de ambientes escolar basados en el desarrollo de una cultura de la paz. En este sentido, consideramos que el significado de la violencia escolar es construido por los

    Full Text Available La recomposición de las é lites políticas mexicanas durante la década de los ochenta se entrevera con la transfor mación del modelo de desarrollo: de uno predominante mente proteccionista y nacionalista a un modelo de corte neoliberal y aperturista. Dicha transformación he implicado cambios de fondo en las prácticas sociales de las é lites políticas. A partir de una base de datos que incluye a todos los funcionarios más importantes del perí odo 1988 - 2014, se investigan los mecanismos que estructuraron una red de poder transexenal y transnacional en México, así como los factores que favorecieron la organización de un campo de poder que se centra cada vez más en la frontera entre los espacios nacionales, regionales y globales. E ntre dichos mecanismos, encontramos : el contexto histórico internacional; la formación de equipos de trabajo con una visión del mundo predominantemente neoliberal; las trayectorias de los funcionarios; las reformas impulsadas ; el fluido tránsito entre posiciones públi cas y privadas; y las muy diversas relaciones que este grupo de funcionarios sostiene con organizaciones y otros actores transnacionales. Se concluye que las nuevas prácticas sociales de la s élites no sólo obstaculizan y socavan la formación de bienes públicos y de estructuras autónomas con la capacidad para planificar en función de un interés general, sino que promueven la depredación institucional.

    2001-11-01

    Full Text Available This study deals with the analysis of evolution of the urban transformations in the lots of Vila Casoni, an old district in Londrina. The sucessivel interventions carried out in order to adequate themselves to the programs, called additive transformations, resulted in the gradual formation of villasconsisting of three to seven units in the same lot. Despite the apparent “invisibility”, for they are situated intramurally, the villas have a dense repertoire of spatial organization, articulation of open spaces, hierarchy and definition of patios. Qualities such as conviviality, defensibility allowing safety to the neighbourhood, alternative of horizontal densification, constitute important aspects for the rehabilitation process. O estudo trata do levantamento e análise das transformações internas em lotes da Vila Casoni, bairro pioneiro em Londrina. Intervenções sucessivas de adequação aos programas, as transformações aditivas, resultaram no surgimento gradual de dezenas de “vilas” constituídas de tres a sete unidades no mesmo lote. Apesar da aparente “invisibilidade” por se localizarem intra quadra, as vilas possuem denso repertório de linguagem de ordenação espacial na sua forma de implantação, articulação dos espaços livres, hierarquia e definição de pátios internos. Qualidades como: suporte à convivialidade, a defensibilidade trazendo segurança, alternativa de adensamento horizontal constituem subsídios importantes ao processo de reabilitação urbana.

Na produção de isomaltulose a partir da sacarose utilizando-se células de Erwinia sp D12 imobilizadas em alginato de cálcio, estudou-se o efeito da temperatura (25 - 35ºC e da concentração de substrato (12,5 - 60% p/v. Foi obtido um rendimento em torno de 50% de isomaltulose, com soluções de sacarose entre 20-30% (p/v a 35ºC. Concentrações em excesso de sacarose (ao redor de 40% p/v afetaram a atividade da célula imobilizada, diminuindo a conversão de sacarose em isomaltulose. O xarope de isomaltulose foi purificado através de cromatografia de troca iônica e o eluato cristalizado por abaixamento de temperatura. Os cristais apresentaram 91,39% de isomaltulose.The glucosyltransferase of Erwinia sp D12 is able to convert sucrose into isomaltulose (6-0-alpha-D-glucopyranosyl-D-fructofuranose, an alternative sugar which presents low cariogenic potential, and can be

    Full Text Available Embora o uso do teatro para mediar e enriquecer processos educacionais não seja uma ideia nova, a forma como é desenvolvido pode servir para a reprodução ou para a transformação da sociedade. O teatrólogo Augusto Boal desenvolveu uma metodologia, à qual denominou de Teatro do Oprimido, para, através da linguagem teatral promover autonomia e capacidade crítica, tornando o espectador em ator. Na sua última obra, editada em 2009, A Estética do Oprimido, levanta uma importante questão contemporânea sobre o papel da estética e suas relações com o poder.

    Full Text Available O presente artigo tem como objetivo analisar as transformações do mundo do trabalho advindas da acumulação flexível do capital, com a finalidade de apontar como, na atual conjuntura, o avanço incessante da precarização e da flexibilização impõe-se como consequência da lógica destrutiva da era neoliberal no Brasil. Assim, argumenta-se, com base na literatura recente, a existência de um processo de precarização social do trabalho no país, por meio da articulação do neoliberalismo, da financeirização da economia e da reestruturação produtiva.

    2003-01-01

    Full Text Available No artigo, considera-se que as transformações que têm marcado nossas sociedades a partir da crise e reestruturação do capitalismo desde as últimas décadas do século XX repercutem fortemente sobre as relações de trabalho, desordenando as relações que conformaram o Estado de Bem-Estar Social e reordenando-as sob a égide da regulação pelo mercado. Considerando o papel central atribuído ao trabalho em nossas sociedades, torna-se relevante discutir as diferentes interpretações sobre os fenômenos emergentes no mundo do trabalho - desde enfoques que apontam para o "fim do trabalho" até os que defendem a permanência da centralidade do trabalho -, refletindo sobre suas implicações sociais. Ressalta-se que o processo veloz de difusão tecnológica em voga vem precarizando as relações de trabalho, ampliando inseguranças e vulnerabilidades e sendo fonte crucial de desigualdade social. Encerra-se o artigo com reflexões sobre o evolver do mundo do trabalho, propondo um olhar crítico a posições extremadas sobre o tema e ressaltando as repercussões desfavoráveis acarretadas pelas mutações em curso, no sentido de advertir sobre conseqüências sociais não desejadas.In this article, the changes that have marked our societies after the crisis and restructuring of capitalism since the last decades of the 20th century are seen as having had great impact over labor relations, disarraying the relations that have shaped the Welfare State and reordering them under market regulation. Considering the central role assigned to work in our societies, it becomes relevant to discuss different interpretations of emergent phenomena in the world of labor - from approaches that point to "the end of work" to those that argue its sustained centrality - reflecting over their social implications. It is underlined that the speedy process of current technological diffusion has been making labor relations precarious, broadening insecurities and

    Full Text Available O objetivo deste trabalho é analisar aspectos condicionantes das transformações e as tipologias presentes na paisagem urbana de Jundiaí na região situada às margens das rodovias Dom Gabriel P. B. Couto e João Cereser, nas proximidades da serra do Japi. A partir da conceituação de Magnoli (1982 de espaços livres, e através da análise de informações de diversas naturezas, como legislações urbanísticas, fotos aéreas e visitas in loco, pode-se afirmar que Jundiaí, cidade-polo do Aglomerado Urbano de Jundiaí (AUJ, caracteriza-se pela presença de grandes áreas de preservação ambiental, como a serra do Japi, e áreas de conservação de mananciais, que impedem a expansão urbana para os vetores sul ou leste, favorecendo o crescimento da forma urbana no sentido noroeste e oeste. Devido à sua localização, num espaço intersticial entre as Regiões Metropolitanas de São Paulo, Campinas e o Aglomerado Urbano de Sorocaba (AUS, a cidade convive com diversas influências socioeconômicas e espaciais decorrentes do processo de metropolização típico da macrometrópole paulista. Assim, as áreas de preservação ambiental, as presenças de espaços livres não urbanizados de grandes proporções e a sinergia de Jundiaí com a rede de cidades dos Aglomerados Urbanos tornaram-se os principais agentes transformadores da paisagem urbana deste território.

  5. Breves considerações sobre processo de transformação da existência dos pescadores artesanais na modernidade

    Dauto João da Silveira

    2012-12-01

    Full Text Available Este artigo tem como objetivo discutir as transformações sociais sofridas pelos pescadores artesanais ao longo da história e o papel das forças produtivas na consolidação destes acontecimentos. Para alcançar estes objetivos usou-se o método materialista-dialético diante do qual as contradições da realidade social engendram elementos decisivos para a superação dos homens. Desse modo, percebeu-se que a modernidade foi responsável não só pela dissolução profunda das vida tradicional dos pescadores artesanais como também criou condições para que eles se apropriassem de novos arranjos materiais.

  6. Transformação genética em espécies florestais.

    Claudia Studart-Guimarães

    2010-08-01

    Full Text Available A transformação genética, que compreende a introdução de genes exógenos de forma controlada no genoma de uma célula vegetal e posterior regeneração da planta transgênica, tem contribuído com os programas de melhoramento genético de plantas pela obtenção de genótipos com novas características de interesse. O melhoramento de espécies florestais é limitado por características intrínsecas a tais espécies, como a altura dos indivíduos e o ciclo longo de vida. A transformação genética constitui, portanto, uma alternativa para a obtenção de espécies florestais com características desejáveis em um menor espaço de tempo. Plantas transgênicas com resistência a determinadas pragas, com melhor qualidade de madeira, maior produção de biomassa, tolerância a herbicidas, entre outras características de interesse, já foram obtidas para diferentes espécies florestais de importância econômica como álamo, eucalipto e pinheiros em geral. Este trabalho mostra a importância da transformação genética, associada a outras técnicas biotecnológicas no melhoramento de espécies florestais, as técnicas de transformação mais utilizadas e as características que já foram introduzidas nessas espécies pela transformação.

  7. Rituais políticos e a transformação do Partido Comunista Italiano

    2001-07-01

    Full Text Available Os rituais exercem um papel central na vida política contemporânea, mesmo que, freqüentemente, este papel não seja reconhecido. Demonstramos, através da análise da transformação, entre 1989-1991, do Partido Comunista Italiano (PCI em um partido pós-comunista, o papel-chave do ritual na política moderna. Ao longo deste caminho, examinamos e ilustramos as maneiras pelas quais os rituais são empregados para propósitos políticos. Após a queda do muro de Berlim, líderes do PCI decidiram que a identidade comunista tornou-se demasiadamente estigmatizada, e que uma nova identidade era necessária para o Partido, para que se evitasse o seu declínio. Desde a metade dos anos 1979, o segundo maior partido da Itália, o PCI, vinha constantemente perdendo suporte eleitoral. Na tentativa de mudar sua identidade, no entanto, os líderes do PCI deparam-se com a grande força do simbolismo associado ao Comunismo na Itália. Para muitos membros, o ser "Comunista" era parte central de sua própria auto-imagem. A oposição dentro do Partido tirou vantagem da força deste simbolismo, e dos ritos associados a ele, para opor-se à mudança. A inabilidade para inventar novos ritos e símbolos que tivessem o mesmo poder, deixou a liderança vulnerável. Este artigo examina esta disputa, pensada através do simbolismo e do ritual, olhando para o processo pelo qual o Partido Comunista Italiano tornou-se o Partido Democrático da Esquerda (PDS.Rituals occupy a central role in contemporary political life, although this role is often not recognized. Through the examination of the transformation, in 1989-1991, of the Italian Communist Party (PCI into a post-communist party, the key role of ritual in modern politics is demonstrated. Along the way, the ways in which rituals are employed for political purposes are examined and illustrated. Following the fall of the Berlin wall, PCI leaders decided that a Communist identity had become too stigmatic, and that a new

  12. Do Génio ao jogo. O papel da Técnica na Transformação dos Valores Estéticos em Walter Benjamin

    Directory of Open Access Journals (Sweden)

    Nélio Rodrigues Conceição

    Full Text Available Resumo: Analisando o papel desempenhado pela questão da técnica no pensamento de Walter Benjamin, o artigo debruça-se sobre a transformação dos valores estéticos, na modernidade. As técnicas de reprodução/registo inventadas nos séculos XIX e XX, como a fotografia e o cinema, obrigaram a uma revisão das articulações entre arte, técnica e história, articulações que Benjamin desenvolveu em diversos sentidos. Contudo, não encontramos, nos seus textos, uma filosofia da técnica de princípios claramente estabelecidos. Portanto, o presente artigo visa estabelecer uma constelação de temas, os quais, brotando dos seus textos, nos permitem clarificar como a técnica influencia a transformação e a criação de valores estéticos, sendo estes entendidos como eixos em torno dos quais se dão a produção e a crítica dos fenómenos estéticos. A fotografia, constituindo um momento de viragem incisivamente estudado pelo autor, é o fio condutor das diferentes leituras. Historicidade da percepção; dimensão política da arte; sua relação com a memória; elemento de jogo: são estes os quatro eixos em torno dos quais se procura clarificar e, sempre que possível, prolongar a proposta benjaminiana.

    2009-09-01

    Full Text Available Em olericultura, o interesse é a produção de frutos comercializáveis. Nesses experimentos, comumente são avaliadas variáveis, tais como a fitomassa e o número de frutos. No entanto, essas variáveis apresentam uma característica particular que está relacionada com sua ausência ou presença no momento da colheita. Esse atributo é representado por valores zeros, para essas variáveis, gerando certa variabilidade e afetando a análise de variância dos dados. Este trabalho teve por objetivo definir uma transformação adequada para as variáveis observadas em experimentos com a cultura da abobrinha italiana, realizados em ambiente protegido, visando a estabilizar a variabilidade gerada pela presença de valores zeros nas múltiplas colheitas dos frutos. Foram analisados experimentos com a cultura da abobrinha italiana utilizando a família de transformações de Box-Cox, com uma adaptação apresentada em YAMAMURA (1999. Concluiu-se que, para experimentos com abobrinha italiana, avaliando a fitomassa e o número de frutos, a transformação indicada é a raiz quarta. Mesmo com redução na variabilidade e a normalidade dos resíduos, observadas em todos os experimentos, o uso do método não foi eficiente para tornar as variâncias homocedásticas.The interest in horticulture is the production of marketable fruit. In such experiments , phytomass and the number of fruits are commonly measured variables. However, these variables have a particular characteristic related to their absence or presence at harvest time. This attribute is represented by zero values for these variables, generating some variability and affecting the variance analysis. This work aimed to define an appropriate data transformation for the variables observed in experiments with the zucchini culture, realized in protected environment, designed to stabilize the variability values generated by the presence of zeros in harvest multiple fruit. The analysis was based on

    Full Text Available As transformações no mundo do trabalho e suas consequências sobre as relações de trabalho enfatizam a importância de se considerar o comprometimento organizacional como um fenômeno que é construído processualmente e que pode se alterar ao longo do tempo, destacando a pertinência da realização de estudos longitudinais. Nesse sentido, o presente trabalho objetiva avaliar o processo de comprometimento afetivo (CA, de comprometimento de continuação (CC, de percepção de suporte organizacional (PSO e de intenção de deixar a organização (IDO, associando-os às transformações organizacionais percebidas pelo gestor e trabalhadores. Foram coletados dados em três organizações de fruticultura irrigada de um mesmo grupo econômico do Vale do São Francisco, em quatro momentos, com intervalos de seis meses. Foram aplicados questionários com questões sobre transformações organizacionais percebidas e quatro escalas: CA, CC, PSO e IDO. Nos quatro tempos, participaram 114, 135, 162 e 162 trabalhadores, respectivamente, tendo 46 participado nos quatro tempos. Os participantes foram, em sua maioria, homens, jovens e de baixa escolaridade. Realizaram-se análises descritivas e comparações de médias. Ao longo dos dois anos investigados, os trabalhadores perceberam mudanças na estrutura física, no processo de trabalho, nas chefias, no quadro de funcionários e destacaram o atraso no pagamento dos salários como uma importante mudança. Na amostra total, observou-se uma redução nas médias de CA e de CC, acompanhadas por uma queda da média de PSO até o tempo 3 e por um aumento de IDO até o tempo 3. A mesma tendência foi observada entre os 46 trabalhadores, tendo ocorrido reduções estatisticamente significativas das médias de PSO entre os tempos 1 e 3, e entre os tempos 2 e 3, e de CA e de CC entre os tempos 2 e 3. Também foi verificado um aumento estatisticamente significativo de IDO entre os tempos 1 e 3. Os achados

Foram avaliadas duas situações: 1ª carreta utilizada e retirada do processo após o fim de sua vida útil; 2ª carreta utilizada, transformada em caminhão truck e, posteriormente, em caminhão toco. A equação diferencial foi utilizada para definir o momento ótimo das transformações. Os resultados obtidos indicaram que, no modelo sem transformação, obteve-se um tempo ótimo de utilização de nove anos, apresentando um Valor Anual Equivalente (VAE de R$4.084,06. No modelo com transformação (carreta/truck/toco, obteve-se um (VAE de R$10.555,04, indicando a viabilidade no sistema de transformação. Com base nos dados de custo e receita utilizados, a transformação (carreta/truck/toco mostrou-se a melhor alternativa. Conclui-se que os modelos desenvolvidos permitem auxiliar a tomada de decisão referente à substituição de veículos de transporte.The objective of this work was to analyse the economic feasibility of the transformation of forest transport vehicles. Two situations were evaluated; in one the cart was used and removed after its useful lifetime, in the other one the cart is transformed in to truck and, finally, in to a two-wheeled cart. The differential equation was used to define the optimal time of the transformations. The results obtained showed that in the model without transformation an optimal time nine years used was defined, presenting an Equivalent Annual Value of R$4,084.06. In the model with transformation (cart/truck/two-wheeled cart, an Equivalent Annual Value of R$10,555.04 was obtained, indicating the viability of the transformation system. Based on data of costs and incomes used the transformation (cart/truck/two-wheeled cart showed to be best alternative.

    Full Text Available O desenvolvimento da agricultura brasileira ao longo do século XX e início deste século XXI provocou grandes transformações no processo produtivo de diversas cadeias agropecuárias. Neste contexto, o Cerrado Mineiro merece destaque particular, pois se consolidou como uma das regiões cafeicultoras mais modernas do país, com a adoção de um conjunto de inovações tecnológicas, cujo resultado foi a obtenção de elevada produtividade e qualidade do café. Entretanto, para se alcançar tal grau de desenvolvimento tecnológico, a estrutura produtiva passou por grandes transformações desde o início dos anos 70 até 2000, inclusive no que diz respeito às relações de trabalho. O objetivo deste artigo é apontar como se deram essas transformações, qual o impacto sobre a produção e o emprego, bem como sobre a organização dos cafeicultores em torno do fortalecimento da cadeia do café. Para alcançar esses objetivos, foi realizada revisão bibliográfica de trabalhos de especialistas da área, além da utilização de dados dos censos agropecuários de 1970 a 2006 e pesquisa de campo junto a produtores e lideranças representativas dos cafeicultores, pesquisadores agronômicos, técnicos de assistência técnica e empresas líderes na comercialização de insumos e equipamentos. Concluiu-se que o processo de modernização da atividade do café no Cerrado Mineiro provocou impactos significativos na ampliação da área produtiva, na produtividade, na geração de novos postos de trabalho em atividades mais qualificadas e redução das menos qualificadas.The development of the Brazilian agriculture over the twentieth century and at the beginning of this century led to major changes in the production process of different agricultural chains. Coffee in the Cerrado Mineiro region deserves special attention in this context; therefore, it has been established as one of the most modern in Brazil, with the adoption of a set of technological

    Directory of Open Access Journals (Sweden)

    Marcelo Garcia Navarro

    2017-03-01

    Full Text Available No presente artigo apresento reflexões acerca da relação entre imaginação e razão, contidas nas obras de Gaston Bachelard e Herbert Marcuse, e a importância de tal discussão para a educação. A docência adquire categoria filosófica porque ela pode estabelecer parâmetros para uma disciplina estética que redimensione a relação da imaginação com a razão. O que se propõe é outro paradigma epistemológico e uma filosofia do psiquismo imaginante. O primeiro sugere rupturas epistemológicas, a segunda, novas possibilidades estéticas. Trata-se de uma disciplina estética que procura compreender a relação dialética e oscilante da imaginação com a razão. Bachelard sugere, para tanto, uma pedagogia psicanalítica que propõe como conceito e método a vigilância intelectual de si, e distingue a censura moral, imbuída de caráter autoritário, do relativismo da vigilância intelectual. O trabalho docente assume posição estratégica na formação e na transformação da cultura quando procura transcender a realidade e considera a possibilidade de construção de um novo mundo. Tal transformação só pode se realizar através da ação de um sujeito histórico, essencialmente novo, que busca autonomia e confronta a mecânica da submissão que impõe os padrões psicológicos e de organização do aparato.

    Directory of Open Access Journals (Sweden)

    Teresa Cristina Schneider Marques

    Full Text Available RESUMO O presente artigo analisa a trajetória política da segunda geração de exilados brasileiros pelo regime militar no Chile e na França, visando compreender a dinâmica das transformações dos repertórios de ação dos migrantes frequentemente observadas nos estudos sobre exílio. Verificou-se que a migração forçada promove uma metamorfose total da estrutura de oportunidades políticas. Como resultado, o exilado se vê inserido em uma estrutura que não é a mesma daquela verificada pelos estudos sobre o confronto político nos enfrentamentos no interior do Estado-Nação e nem mesmo pelos movimentos transnacionais globais mais atuais. Com efeito, no Chile os exilados apresentaram um repertório adaptado às particularidades do exílio chileno, tendo como foco a continuidade do confronto travado com o regime brasileiro. Na França, por sua vez, eles viveram transformações profundas, ao abandonar o projeto revolucionário e adotar os direitos humanos e a democracia, entre outras reivindicações até então novas para a esquerda brasileira.

    1999-10-01

    Full Text Available Este ensaio visa propor uma reflexão sobre as mudanças na sensibilidade musical no mundo ocidental neste fim de século. As profundas transformações na tecnologia da produção musical ocorridas nas últimas décadas provocaram uma alteração dramática do lugar que a música ocupa na sociedade e também para o indivíduo. Interpreto o impacto dessas mudanças através de quatro elementos de análise profundamente interrelacionados: a tecnologia de gravação e reprodução, a execução musical, a recepção do produto musical e as subculturas musicais que condicionam as opções de uma vasta gama de consumidores de música, jovens e velhos. Na tentativa de construir uma sensibilidade musical deveras pluralista, procurei ilustrar esses argumentos com exemplos musicais retirados dos estilos mais diversos: eruditos, tradicionais, populares, massificados, folclóricos, ritualizados, etc. Dialogo também com teorias da música e da cultura contemporânea que cobrem um amplo eixo da Musicologia e da Etnomusicologia, de Béla Bártok, Adorno e Benjamin a John Blacking, Jacques Attali, Jean Baudrillard, Simon Frith, Lawrence Kramer, entre outros.

    2011-10-01

    Full Text Available É consenso a relação das atividades comerciais com a estruturação das cidades. Desde as primeiras cidades o mercado, enquanto forma e função, apresenta papel de destaque nesse processo. Todavia, enquanto palco, e ao mesmo tempo, condicionante para a reprodução das relações sociais, a cidade e seus múltiplos usos apresentam-se em constante transformação de acordo com os anseios da sociedade ao longo de cada período histórico. Sendo que, nos mercados públicos, espaços voltados não só para a comercialização, mas também para a socialização, é possível apreender elementos e produtos típicos de uma dada cidade, região ou país, os quais são cada vez mais valorizados enquanto mercadorias capazes de atrair fluxos e assegurar a permanência dos destes nos dias atuais. Neste sentido, este trabalho tem como objetivo analisar a dinâmica do Mercado Municipal de Uberlândia a fim de compreender o papel do Mercado Municipal ao longo de sua existência. Para tanto fez-se necessário a realização de um levantamento do referencial teórico a cerca da temática em questão, bem como de trabalhos de campo. A partir da concretização desse trabalho tem-se que o Mercado Municipal de Uberlândia assumiu distintas configurações, de acordo com os desígnios dos períodos históricos.

Neste buscamos compreender e refletir as lutas e reinvindicações dos movimentos sociais negros a partir das estruturas impostas pelos sistemas de poder que, mediante as crises e os avanços cíclicos no sistema capitalista, pouco ou nada alteram a força estruturante do racismo na sociedade brasileira. Destacam-se também as reações e manifestações racistas frente à implementação das políticas de promoção da igualdade racial no século XXI, que, em regra, advogam a manutenção do status quo nos espaços de poder.

A proporção das bactérias com atividade enzimática em relação ao total variou de 25 a 87% e, a dos fungos, de 2 a 36%. Os grupos de bactérias aumentaram sua população nas parcelas em que se aplicou superfosfato e calcário em relação aos outros tratamentos (exceto as ureolíticas que aumentaram na ausência de adubo e os fungos prevaleceram na ausência de adubação (exceto os ureolíticos que aumentaram com superfosfato e de calagem. No solo cultivado com braquiária, foram obtidas as maiores contagens de bactérias ureolíticas e fungos proteolíticos. Na ausência de planta, preponderaram os fungos CM-celulolíticos (CM, celulose microcristalina e ureolíticos e na presença de guandu, os amilolíticos e CMC-celulolíticos (CMC, carboximetilcelulose. Os demais grupos de bactérias não foram influenciados pelo sistema de cultivo. A população e a habilidade enzimática dos fungos foram menores que as das bactérias, o que sugere menor participação na transformação dos nutrientes no solo. As bactérias apresentaram múltiplas atividades enzimáticas, mostrando maior versatilidade que os fungos.

    Maria Conceição Barletta Scussel

    Full Text Available Num contexto global de urbanização crescente e de transformações acentuadas no espaço das cidades, destacam-se os processos peculiares à dinâmica das grandes cidades brasileiras, que alteram substancialmente sua configuração, promovendo rupturas no tecido urbano consolidado e nas práticas de apropriação e uso desse espaço, comprometendo sua sustentabilidade. A partir dessa perspectiva, o objetivo do presente trabalho é analisar o impacto do processo de verticalização e adensamento na qualidade do espaço residencial de um bairro de Porto Alegre (RS, promovido por alterações na legislação urbanística. Mediante estudo de caso, realizou-se análise comparativa de diferentes quarteirões, utilizando-se método de avaliação da Qualidade do Espaço Residencial (QER. Os procedimentos adotados incluem a análise de documentos, levantamentos a campo e observação direta. Apresentam-se os resultados da aplicação do método de avaliação QER, em termos de qualidade do espaço da habitação, qualidade do contexto da habitação, qualidade do espaço dos serviços, qualidade dos percursos casa / serviços, apontando diferenças significativas entre quarteirões que sofreram verticalização acentuada e quarteirões que mantiveram a tipologia original. A principal contribuição deste artigo reside em explorar o potencial de uso da ferramenta QER para ilustrar o impacto da aplicação de legislação urbanística, instrumentando a discussão do modelo espacial de desenvolvimento da cidade.

  20. Assessing call centers’ success:

    2013-07-01

    This paper introduces a model to evaluate the performance of call centers based on the Delone and McLean Information Systems success model. A number of indicators are identified to track the call center’s performance. Mapping of the proposed indicators to the six dimensions of the D&M model is presented. A Weighted Call Center Performance Index is proposed to assess the call center performance; the index is used to analyze the effect of the identified indicators. Policy-Weighted approach was used to assume the weights with an analysis of different weights for each dimension. The analysis of the different weights cases gave priority to the User satisfaction and net Benefits dimension as the two outcomes from the system. For the input dimensions, higher priority was given to the system quality and the service quality dimension. Call centers decision makers can use the tool to tune the different weights in order to reach the objectives set by the organization. Multiple linear regression analysis was used in order to provide a linear formula for the User Satisfaction dimension and the Net Benefits dimension in order to be able to forecast the values for these two dimensions as function of the other dimensions

A interpretação e a análise da relação estabelecida são feitas à luz de teorias antropológicas acerca da centralidade que corpo, corporalidade e processos corporais degenerativos ocupam nas sociedades indígenas brasileiras. Propõe-se que corpo, sociedade e agentes macroconjunturais são articulados pela práxis; por isso, devem ser relacionados nos estudos socio-antropológicos concernentes aos fenômenos de doença. O artigo traz a descrição sucinta das epidemias advindas com o contato, tentando vinculá-las aos contextos históricos específicos que o marcaram. Categorias da etnomedicina, cosmologia e corporalidade Xokléng são associadas à organização social e aos casos de AIDS.

Para responder a esta questão - objetivo deste estudo -, procedeu-se a uma pesquisa qualitativa com os discentes matriculados no quinto período do curso, por meio de entrevistas, as quais foram categorizadas e analisadas. Os resultados evidenciaram significativa receptividade ao novo modelo curricular, pelo entendimento de que este é capaz de suscitar novas reflexões dirigidas à futura prática do estudante, e, igualmente, ao conceito de saúde e ao processo de adoecimento. Verificou-se, ainda, que a opção precoce por uma especialidade, expressa pela maior parte dos entrevistados, não foi alterada sob o novo currículo e que a formação do médico como generalista ou médico de família é ainda pouco valorizada.

    Full Text Available A exposição ao ruído no trabalho é o fator de risco modificável mais importante para a perda auditiva em adultos. Na indústria de transformação, a exposição a níveis elevados de pressão sonora afeta um grande número de trabalhadores. As normas brasileiras estabelecem como obrigatório, para todas as empresas, o monitoramento do ruído ocupacional e da condição auditiva dos trabalhadores, assim como garantias para a proteção do trabalhador. No entanto, a aplicação das normas é frágil e pouco se sabe sobre a distribuição de exposição ao ruído no País. Este estudo tem como objetivo investigar e sumarizar a distribuição da exposição ao ruído e do uso do equipamento de proteção auditiva entre trabalhadores da indústria de transformação no Brasil. A menor prevalência de exposição ao ruído dentre os ramos da indústria da transformação é de 45% e poucos são os dados sobre o uso do equipamento de proteção auditiva entre os trabalhadores expostos. Comparando-se os disponíveis para os diferentes ramos de atividade, a exposição ao ruído alcança níveis mais altos no ramo da fabricação de produtos de madeira, onde também se observa a menor proporção de uso do equipamento de proteção auditiva. A escassez de dados sobre as condições de trabalho, exposição ao ruído e proteção auditiva, limita os esforços em fazer com que a saúde auditiva seja incluída entre as prioridades da saúde pública no Brasil.Occupational noise exposure is the most important modifiable risk factor for hearing loss in adults.

Esta pode ser uma ferramenta importante para os melhoristas, pois, além de aumentar a variabilidade genética existente, torna possível criar variabilidade não disponível via métodos de melhoramento convencional. No entanto, ainda existem algumas dificuldades a serem superadas para que os genes de interesse agronômico sejam incorporados no genoma dos cereais, como aidentificação de estirpes de bactérias que infectem monocotiledôneas e a adequação da técnica. O objetivo deste trabalho é de revisar as potencialidades e problemas do uso da A. tumefaciens para transformação de cereais no presentemomento e abordar suas perspectivas futuras. Trabalhos recentes com arroz e trigo indicam que estas culturas podem ser transformadas com A. tumefaciens, sendo que em arroz plantas transgênicas foram obtidas com este método. Esta tecnologia vem sendo aprimorada e a curto prazo possibilitará a transferência de genes para diversas espécies monocotiledôneas.The genetic transformation via Agrobacterium tumefaciens allows the insertion of one or few copies of a transgene into the host DNA. This can be an important tool to plant breeders because it expands the genetic variability in breeding programs, developing variability not readily available from traditional methods. However, there are some difficulties that have to be overcome before this technology may be used in cereals, as the identification of highly ineffective bacteria strains and the adjustments of the technique to various crops. The objective of this paper is to revise the potentialities and limitations of using A. tumefaciens to transform cereals and to indicate the future perspectives of this technology. Recent studies have indicated that it is possible to transform rice and wheat with A. tumefaciens, so that rice

Estes foram co-cultivados com Agrobacterium tumefaciens (EHA-105, realizando-se vários experimentos para avaliar a eficiência do processo de transformação genética: explantes co-cultivados por um, três e cinco dias; tempo de inoculação com a bactéria de 5, 10, 20 e 40 minutos; co-cultivo em meio de cultura contendo 0, 100 e 200 mimol L-1 de acetoseringona; Incisão longitudinal (2-3 mm nas extremidades do explante; temperatura de co-cultivo 19, 23 e 27°C. Todos os experimentos consistiram de cinco repetições por tratamento, sendo cada repetição representada por uma placa de Petri contendo 30 explantes, perfazendo um total de 150 explantes por tratamento. Plântulas transgênicas dos três cultivares foram obtidas utilizando-se tempo de inoculação de 20 minutos, co-cultivo com Agrobacterium tumefaciens (EHA-105 por três dias, na ausência de acetoseringona no meio de cultura de co-cultivo e temperatura de co-cultivo de 23-27°C. A incisão longitudinal na extremidade do explante favoreceu à organogênese in vitro, mas quando co-cultivado com Agrobacterium não houve regeneração de brotações.

    Full Text Available Em olericultura, o interesse é a produção de frutos comercializáveis. Em experimentos nessa área agronômica comumente são avaliadas variáveis tais como a fitomassa e o número de frutos. No entanto, essas variáveis apresentam uma característica particular que está relacionada com sua ausência no momento da colheita. Este atributo é representado por valores zero, gerando certa variabilidade e afetando a análise de variância dos dados. Assim, teve-se por objetivo definir uma transformação adequada para as variáveis observadas em colheitas por planta de experimentos com a cultura do pimentão, realizados em ambiente protegido, visando estabilizar a variabilidade gerada pela presença de valores zero nas múltiplas colheitas dos frutos. Os experimentos foram realizados nas estações sazonais verão/outono e inverno/primavera, utilizando a família de transformações de Box-Cox, com uma adaptação apresentada em Yamamura (1999. Apesar da redução na variabilidade e a normalidade dos resíduos, observadas em todos os experimentos, o uso do método não foi eficiente para tornar as variâncias homocedásticas. Concluiu-se que para dados de colheitas por planta de experimentos com pimentão, avaliando a fitomassa e o número de frutos, a transformação indicada é a inversa da raiz quarta.The major purpose of vegetable crops production systems is the profitable and economically viable yield of marketable products. Numerous field experiments with vegetable crops are carried out to determine biomass production of marketable and non-marketable variables. However, these variables possess the particular characteristic related to their presence or absence at harvest time. Absent variables, represented by zero values, generate variability and affect variance analyses. This research deals with the search of applicable transformations for variables studied in green pepper field experiments carried out in protected environments attempting

    Full Text Available O fenômeno religioso no Brasil vem atraindo crescente atenção da academia, impulsionado, em grande parte, pela expansão das seitas protestantes no país, sobretudo de vertente pentecostal. Na esteira dessa transformação, um tema, em particular, reveste-se de especial importância. Trata-se do papel dos chamados empreendedores religiosos aqui compreendidos como os novos pastores evangélicos. No entanto, tais atores não vêm sendo muito estudados. O presente trabalho busca preencher essa lacuna. Recorre-se, para isso, às contribuições teóricas clássicas derivadas de Weber, em associação às contribuições contemporâneas originárias de Granovetter, em particular, sobre acoplamento e desacoplamento. Conclui-se o trabalho propondo um novo referencial para a análise de certas dimensões do empreendedorismo religioso.

    Full Text Available The obtaining of commercial cultivars of potato with resistance to the phytopatogen is a very promising alternative that the genetic engineering can provide, through the introduction of exogenous genes for the genetic transformation. In order to establish an efficient system of transformation, it is crucial first to optimize in vitro organogenesis protocol. This work aimed to establish an efficient protocol for the genetic transformation of potato cv. Atlantic. The efficiency of the in vitro organogenesis is influenced by the explant type and by the kind and concentrations of growth regulators used. Shoot segments of potato cv. Atlantic present better organogenesis capacity than leaf explants. It is recommended to use the woody plant medium (WPM supplied with 1,0 mg L-1 of naphthalene acetic acid (NAA + 5,0 mg L-1 of zeatin riboside (ZEA, to obtain shoots from shoot segments, and the carbenicilin (Cb added to this medium increased this formation. For the process to enlarge shoots, this same antibiotic when added to the WPM medium in growing concentrations (100; 250; 500 mg L-1 promoted a decrease in the height of plants, number of shoots and length of roots. After the co-cultivation of shoots segments with Agrobacterium tumefaciens these concentrations of Cb are not efficient in the elimination of the bacteria, which commits the organogenesis. However, it is possible to establish a protocol of in vitro organogenesis of potato cv. Atlantic starting from shoots segments not co-cultivated. These results will be useful for futures experiments of genetic transformation with this and another commercials cultivars of potato.A obtenção de cultivares comerciais de batata com resistência a fitopatógenos é uma alternativa muito promissora que a engenharia genética pode proporcionar, através da introdução de genes exógenos visando transformação genética.

    2018-02-01

    Full Text Available Resumo O objetivo deste trabalho é apresentar uma metodologia para análise da influência das transformações urbanas no conforto acústico de um espaço urbano. Esta avaliação é baseada em um estudo-piloto, utilizando como objeto de análise a Cidade Universitária da Universidade Federal do Rio de Janeiro, na qual diversas transformações urbanas vêm ocorrendo ao longo dos anos, muitas destas definidas pelo Plano Diretor da UFRJ para o ano de 2020. A avaliação do impacto das transformações foi realizada através da comparação dos mapas de ruído produzidos pelas diversas configurações urbanas, principalmente as viárias e morfológicas das edificações. A validação dos mapas foi realizada através da medição dos níveis de pressão sonora nos pontos de interesse. Os mapas foram gerados utilizando dados de contagens veiculares e levantamento da tipologia física local. Os resultados da análise dos mapas, em função das transformações urbanas, permitiram constatar que os níveis de ruído na área estão acima dos recomendados legalmente e identificar as principais causas dessa elevação de ruído. Dessa forma, foi possível realizar uma análise crítica das transformações ao longo do tempo e da configuração espacial atual, para propor medidas mitigadoras da poluição sonora e obter um quadro de maior conforto acústico na Ilha do Fundão, sede da Cidade Universitária da UFRJ.

    Full Text Available Em O Instinto da Linguagem, Steven Pinker discorre sobre sua célebre tese: a linguagem não é a mais prodigiosa invenção cultural humana. Ela é uma peça da constituição biológica do cérebro. A linguagem é uma habilidade complexa e especializada, que se desenvolve espontaneamente na criança, sem qualquer esforço consciente ou instrução formal, que se manifesta sem que se perceba sua lógica subjacente, que é qualitativamente a mesma em todo indiví­duo, e que difere de capacidades mais gerais de processamento de informações ou de comportamento inteligente. Para Pinker, a concepção de linguagem como um tipo de instinto transmite a idéia de que as pessoas sabem falar mais ou menos da mesma maneira que as aranhas sabem tecer suas teias. Ele apóia suas idéias em Darwin e Chomsky. Palavras-chave linguagem, gramática universal, evolução Abstract In Language Instinct, Steven Pinker argues about his famous thesis: language is not the most prodigious human cultural invention. It is a distinct piece of the biological constitution of the brain. Language is a complex, specialized skill, which develops spontaneously in the child, without conscious effort or formal instruction. It reveals itself without awareness of its underlying logic, which is qualitatively the same in every individual, and which is distinct from more general abilities of information processing of intelligent behavior. According to Pinker, the conception of language as a kind of instinct conveys the idea that people know how to talk in more or less the same way as spiders know how to spin webs. His thesis is founded in Darwin and Chomsky-s theories. Keywords language, universal grammar, evolution

    To establish the validity of various proposed structural models, we have investigated the structure of the binary As x Se 100-x chalcogenide glass family (x≤40) by high-resolution x-ray photoelectron spectroscopy. From the composition dependence of the valence band, the contributions to the density of states from the 4p lone pair electrons of Se and the 4p bonding states and 4s electrons of Se and As are identified in the top part of the band. The analysis of Se 3d and As 3d core-level spectra supports the so-called chain crossing model for the atomic structure of Se-rich As x Se 100-x bulk glasses. The results also indicate small deviations (∼3-8%) from this model, especially for glass compositions with short Se chains (25 40 Se 60 and of Se-Se-Se fragments in a glass with composition x=30 is established

  10. Calling to Nursing: Concept Analysis.

    Science.gov (United States)

    Emerson, Christie

    The aims of this article are (a) to analyze the concept of a calling as it relates nursing and (b) to develop a definition of calling to nursing with the detail and clarity needed to guide reliable and valid research. The classic steps described by Walker and Avant are used for the analysis. Literature from several disciplines is reviewed including vocational psychology, Christian career counseling, sociology, organizational management, and nursing. The analysis provides an operational definition of a calling to nursing and establishes 3 defining attributes of the concept: (a) a passionate intrinsic motivation or desire (perhaps with a religious component), (b) an aspiration to engage in nursing practice, as a means of fulfilling one's purpose in life, and (c) the desire to help others as one's purpose in life. Antecedents to the concept are personal introspection and cognitive awareness. Positive consequences to the concept are improved work meaningfulness, work engagement, career commitment, personal well-being, and satisfaction. Negative consequences of having a calling might include willingness to sacrifice well-being for work and problems with work-life balance. Following the concept analysis, philosophical assumptions, contextual factors, interdisciplinary work, research opportunities, and practice implications are discussed.

    Full Text Available Transformações mineralógicas e cristaloquímicas foram investigadas em amostras de argilas cauliníticas ferruginosas aquecidas a temperaturas de 800, 1000 e 1200 °C. As análises de difração de raios X e térmica diferencial e gravimétrica mostraram ser a caulinita o argilomineral predominante nas amostras naturais. Os resultados da espectroscopia Mössbauer mostraram que o alto conteúdo em Fe (22,5% em peso, determinado por fluorescência de raios X, é relacionado à presença de goethita (18% em peso e hematita (16% em peso. Entretanto um resíduo deste elemento (Fe3+ e Fe2+ foi constatado após a extração do ferro usando solução de ditionito-citrato-bicarbonato, e possivelmente se deve à presença de ferro na estrutura da caulinita. O processo de sinterização mostra uma desestruturação da caulinita, assim como a transformação da goethita em hematita, cujo tamanho dos cristais cresce com o incremento da temperatura. O tamanho do cristal de hematita a 1200 °C é 5 vezes maior do que na amostra natural. A mulita formada a 1000 °C é constituída da solução sólida de Fe2O3, com Al2O3, o que resulta em produto resistente e de maior estabilidade térmica.Mineralogical and crystallochemical transformations of representative ferruginous kaolinitic clay samples were investigated in specimens burned at 800, 1000 and 1200 °C. X-ray diffraction and differential thermal and thermogravimetric analyses showed that kaolinite was the predominant mineral in the raw samples. The Mössbauer spectroscopy results showed that the high iron content (22.5 wt.%, as determined by X-ray fluorescence, is related to the presence of goethite (18 wt.% and hematite (16 wt.%. However, after Fe was extracted using a dithionite-citrate system buffered with sodium bicarbonate, a residue of this element (Fe3+ and Fe2+ was found in the structure of the kaolinite. The sintering process showed the destruction of kaolinite, as well as the transformation of

    Full Text Available Cold cracking resistance is a relevant evaluation criterion for welded joints and affected by residual stresses which result from the welding procedure. Compressive residual stresses can thereby have a positive influence on preventing cracking. A unique possibility of generating compressive residual stresses already during the welding procedure is offered by the so-called Low Transformation Temperature (LTT filler wires. Compared to conventional wires, these materials show decreased phase transformation temperatures which can work against the cooling-specific contraction. In consequence, distinct compressive residual stresses can be observed within the weld and adjacent areas. The strength of these fillers makes them potentially applicable to high-strength steel welding. Investigations were carried out to determine the phase transformation behaviour of different LTT-filler materials. Transformation temperatures were identified using Single Sensor Differential Thermal Analysis (SS-DTA. Additionally Synchrotron radiation was used to measure the transformation kinetics of all involved crystalline phases during heating and cooling of a simulated weld thermal cycle.Fissuração a frio é um critério de avaliação relevante para juntas soldadas, sendo afetada pelas tensões residuais resultantes da soldagem. Neste contexto, tensões residuais de compressão podem ter uma influência positiva no sentido de prevenir a fissuração. Uma possibilidade única de já gerar tensões residuais de compressão já durante a execução da soldagem é oferecida pelos materiais de adição conhecidos como de "baixa temperatura de transformação" (BTT. Comparados com metais de adição convencionais, esses apresentam uma temperatura de transformação de fase inferior a qual pode contrapor a contração térmica do material durante o seu resfriamento. Como resultado, claras tensões residuais compressivas podem ser observadas na soldas e áreas adjacentes. A

    Full Text Available The vocal repertoire of some animal species has been considered a non-invasive tool to predict distress reactivity. In rats ultrasound emissions were reported as distress indicator. Capybaras[ vocal repertoire was reported recently and seems to have ultrasound calls, but this has not yet been confirmed. Thus, in order to check if a poor state of welfare was linked to ultrasound calls in the capybara vocal repertoire, the aim of this study was to track the presence of ultrasound emissions in 11 animals under three conditions: 1 unrestrained; 2 intermediately restrained, and 3 highly restrained. The ultrasound track identified frequencies in the range of 31.8±3.5 kHz in adults and 33.2±8.5 kHz in juveniles. These ultrasound frequencies occurred only when animals were highly restrained, physically restrained or injured during handling. We concluded that these calls with ultrasound components are related to pain and restraint because they did not occur when animals were free of restraint. Thus we suggest that this vocalization may be used as an additional tool to assess capybaras[ welfare.

    Full Text Available The objective of this work was to develop a genetic transformation system for tropical maize genotypes via particle bombardment of immature zygotic embryos. Particle bombardment was carried out using a genetic construct with bar and uidA genes under control of CaMV35S promoter. The best conditions to transform maize tropical inbred lines L3 and L1345 were obtained when immature embryos were cultivated, prior to the bombardment, in higher osmolarity during 4 hours and bombarded at an acceleration helium gas pressure of 1,100 psi, two shots per plate, and a microcarrier flying distance of 6.6 cm. Transformation frequencies obtained using these conditions ranged from 0.9 to 2.31%. Integration of foreign genes into the genome of maize plants was confirmed by Southern blot analysis as well as bar and uidA gene expressions. The maize genetic transformation protocol developed in this work will possibly improve the efficiency to produce new transgenic tropical maize lines expressing desirable agronomic characteristics.O objetivo deste trabalho foi desenvolver um sistema de transformação genética para genótipos tropicais de milho pelo bombardeamento de embriões imaturos com micropartículas.

    A field of primate linguistics is gradually emerging. It combines general questions and tools from theoretical linguistics with rich data gathered in experimental primatology. Analyses of several monkey systems have uncovered very simple morphological and syntactic rules and have led to the development of a primate semantics that asks new questions about the division of semantic labor between the literal meaning of monkey calls, additional mechanisms of pragmatic enrichment, and the environmental context. We show that comparative studies across species may validate this program and may in some cases help in reconstructing the evolution of monkey communication over millions of years. Copyright © 2016.

    Meng, Shuang; Schroeder, B. R.; Olmstead, Marjorie A.

    2000-01-01

    Deposition of Se and GaSe on Si(111)7x7 surfaces was studied with low-energy electron diffraction, x-ray photoelectron spectroscopy, and x-ray photoelectron diffraction to probe initial nucleation and interface structure for GaSe/Si(111) heteroepitaxy. Room-temperature deposition of Se on Si(111)7x7 results in an amorphous film. Subsequent annealing leads to Se evaporation without ordering or interdiffusion. Se deposition at 450 degree sign C saturates at submonolayer coverage with no diffusion of Se into the substrate. There is no clear evidence of ordered sites for the Se. Growth of GaSe on Si(111)7x7 above 500 degree sign C results in a pseudomorphic bilayer, with Si-Ga-Se bonding. Additional GaSe does not stick to the bilayer above 525 degree sign C. The resulting Se lone pair at the surface leads to an ideally passivated surface similar to As/Si(111). This stable surface is similar to the layer termination in bulk GaSe. The single domain bilayer is oriented with the Ga-Se bond parallel to the substrate Si-Si bond. (c) 2000 The American Physical Society

Este trabalho teve como objetivo investigar a experiência de tornar-se avó e sua importância no processo de individuação. Foi utilizado delineamento de estudo de caso coletivo. Onze avós maternas, com idades entre 49 e 66 anos, cujas filhas tiveram seu primeiro filho, responderam a uma entrevista semi-estruturada. Todas as avós tinham tido seus primeiros netos e a entrevista referia-se a sua experiência como avós desses netos. Os dados mostraram que o ser avó é uma fonte de renovação e renascimento. O estudo propiciou que as participantes refletissem sobre seus diferentes papéis familiares: avó, mãe, neta e filha. Os dados sugerem que tornar-se avó possibilita que antigos conflitos sejam repensados, renovando antigos vínculos e desejos, o que permite que a avó dê mais um passo rumo à sua individuação.

  1. Hornbills can distinguish between primate alarm calls.

    Science.gov (United States)

    Rainey, Hugo J.; Zuberbühler, Klaus; Slater, Peter J. B.

    2004-01-01

    Some mammals distinguish between and respond appropriately to the alarm calls of other mammal and bird species. However, the ability of birds to distinguish between mammal alarm calls has not been investigated. Diana monkeys (Cercopithecus diana) produce different alarm calls to two predators: crowned eagles (Stephanoaetus coronatus) and leopards (Panthera pardus). Yellow-casqued hornbills (Ceratogymna elata) are vulnerable to predation by crowned eagles but are not preyed on by leopards and might therefore be expected to respond to the Diana monkey eagle alarm call but not to the leopard alarm call. We compared responses of hornbills to playback of eagle shrieks, leopard growls, Diana monkey eagle alarm calls and Diana monkey leopard alarm calls and found that they distinguished appropriately between the two predator vocalizations as well as between the two Diana monkey alarm calls. We discuss possible mechanisms leading to these responses. PMID:15209110

Un sitio se hace lugar, a partir de la apropiación cultural que la gente hace de él, desde el pensar, el construir y el habitar. Pensar el espacio público signifca considerarlo como estructurador y ordenador de la ciudad. Se hace necesario pensarlo desde la posibilidad de incrementar valores de inclusión; allí se producen los encuentros, se socializan, se realizan como ciudadanos y como sujetos políticos de una democracia. Construir en el espacio público, se introduce en la esfera del hacer y en la necesidad de reflexionar sobre el cómo hacer. Es posible hacer más con menos, la austeridad formal y material tiene hoy valor de compromiso ético con la sociedad. Habitar en el espacio público es complejo. A partir de la apropiación social, del ser vividos y usados, es que los mismos adquieren su verdadera dimensión. Estos se transforman cada vez más, en el escenario crítico de una sociedad de consumo masifcada y excluyente. Se presenta la ciudad como el escenario de la cultura y sus espacios públicos, como lugares claves en la construcción de la trama social, como marco para la conformación de identidades.

    Physical ageing effects caused by prolonged natural storage are recorded for binary As{sub x}Se{sub 1-x} glasses with 0.2{<=}x<0.4. Their origin is associated with pure 'shrinkage' of under-constrained glass networks. It is shown that only stoichiometric As{sub 2}Se{sub 3} composition, which network is formed by a so-called self-organized phase, possesses the ideal non-ageing ability.

    Full Text Available O presente artigo visa à análise da transformação da temporalidade, como elemento chave para a compreensão das mudanças no mundo do trabalho. Tomamos como referente dessa análise as teorias dos tempos sociais e a idéia do tempo dominante na constituição dos quadros temporais das sociedades. A passagem de um modelo de temporalidade relativamente estável e quase hegemônica do modelo industrial, para um tempo cada vez mais diversificado e diluído, advindo das novas jornadas - com durações e ritmos cada vez mais complexos - não parece ser suficiente, ainda, para atribuir a perda desse domínio do trabalho na estruturação dos quadros temporais.The present article aims to analyze transformations of temporality in the context of labor as a key element for understanding the changes in its realm. As reference for this analysis we use the theories of social time and the idea of dominant time in the constitution of the temporal frames of societies. The change from a model of relatively stable and almost hegemonic temporality of the industrial model for a more diversified and diluted time, resulting from new types of daytime jobs - controlled by more complex durations and rhythms - it still does not seem to be enough to attribute the loss of this domain of labor in constituting temporal frames.

  18. Long-distance calls in Neotropical primates

    Directory of Open Access Journals (Sweden)

    Oliveira Dilmar A.G.

    2004-01-01

    Full Text Available Long-distance calls are widespread among primates. Several studies concentrate on such calls in just one or in few species, while few studies have treated more general trends within the order. The common features that usually characterize these vocalizations are related to long-distance propagation of sounds. The proposed functions of primate long-distance calls can be divided into extragroup and intragroup ones. Extragroup functions relate to mate defense, mate attraction or resource defense, while intragroup functions involve group coordination or alarm. Among Neotropical primates, several species perform long-distance calls that seem more related to intragroup coordination, markedly in atelines. Callitrichids present long-distance calls that are employed both in intragroup coordination and intergroup contests or spacing. Examples of extragroup directed long-distance calls are the duets of titi monkeys and the roars and barks of howler monkeys. Considerable complexity and gradation exist in the long-distance call repertoires of some Neotropical primates, and female long-distance calls are probably more important in non-duetting species than usually thought. Future research must focus on larger trends in the evolution of primate long-distance calls, including the phylogeny of calling repertoires and the relationships between form and function in these signals.

    2011-11-01

    Full Text Available Resumo: O propósito deste artigo é o de discutir a introdução do turismo rural no povoado Terra Caída no município de Indiaroba, em Sergipe. Especificamente, pretendeu-se caracterizar os aspectos físicos e culturais que sustentam a prática do turismo local e identificar as estratégias utilizadas pela comunidade para inserção na prática do turismo. Para o desenvolvimento deste trabalho foram realizadas pesquisa bibliográfica e documental, complementadas pelos trabalhos de campo, com observação direta e sistemática e entrevistas com líderes comunitários. O povoado tem na pesca tradicional a sua principal fonte de ocupação e renda, a qual, nos últimos tempos, vem apresentando transformações quanto ao potencial de produção e garantia de ocupação dos habitantes da localidade, além de ser pressionada pelas atividades de carcinicultura, com sérias transformações na (reorganização sócio espacial e territorial da localidade. Também foram considerados para esta reflexão os aspectos do turismo no espaço rural de base comunitária como fator de reorganização territorial e desenvolvimento local. Para tanto, analisou-se o nível de organização social local e sua interface com o desenvolvimento do turismo, bem como o papel da Associação pela Cidadania dos Pescadores e Moradores do Povoado Terra Caída, Município de Indiaroba/SE, na implementação do turismo local. Nos resultados observaram-se os fatores determinantes para a inserção da comunidade na atividade turística frente ao modelo adotado pelas políticas públicas e iniciativa privada. Conclui-se que o fetiche promovido pela atividade turística foi percebido pelas lideranças locais que acreditavam nessa alternativa. Percebeu-se, no entanto, que as estratégias implementadas pela comunidade local apresentam-se fragilizadas, necessitando de novos impulsos. Palavras-chave: Turismo. Meio Rural.

    To improve patient satisfaction ratings and decrease readmissions, many organizations utilize internal staff to complete postdischarge calls to recently released patients. Developing, implementing, monitoring, and sustaining an effective call program can be challenging and have eluded some of the renowned medical centers in the country. Using collaboration with an outsourced vendor to bring state-of-the-art call technology and staffed with specially trained callers, health systems can achieve elevated levels of engagement and satisfaction for their patients postdischarge.

  13. Call Duration Characteristics based on Customers Location

    2014-05-01

    Full Text Available Nowadays a lot of different researches are performed based on call duration distributions (CDD analysis. However, the majority of studies are linked with social relationships between the people. Therefore the scarcity of information, how the call duration is associated with a user's location, is appreciable. The goal of this paper is to reveal the ties between user's voice call duration and the location of call. For this reason we analyzed more than 5 million calls from real mobile network, which were made over the base stations located in rural areas, roads, small towns, business and entertainment centers, residential districts. According to these site types CDD’s and characteristic features for call durations are given and discussed. Submitted analysis presents the users habits and behavior as a group (not an individual. The research showed that CDD’s of customers being them in different locations are not equal. It has been found that users at entertainment, business centers are tend to talk much shortly, than people being at home. Even more CDD can be distorted strongly, when machinery calls are evaluated. Hence to apply a common CDD for a whole network it is not recommended. The study also deals with specific parameters of call duration for distinguished user groups, the influence of network technology for call duration is considered.

    Full Text Available São discutidas as transformações sociais e econômicas que incidem sobre a vida dos idosos decorrentes do aumento da população de 60 anos ou mais, no Brasil. O processo migratório e a intensa urbanização (em 1940 a população rural era de 68,8% e em 1980 de 32,4% afetaram particularmente a população idosa dos grandes centros, ou daqueles que envelheceram nestas cidades. Esta nova organização social acentuou os problemas de solidão e pobreza dos idosos. Além desta perda de status social que exclui sua participação na sociedade moderna, o idoso teve também reduzido o suporte emocional no interior de sua família. Entre os fatores que concorrem para tal, destacam-se a mudança do padrão do modelo familiar, de extensa para nuclear, a maior mobilidade e o aumento do número de separações e divórcios. O maior período de vida da mulher e suas conseqüências (redução de renda, aumento do número de viúvas e maior freqüência de longos períodos de doenças crônicas, como também a mudança do papel social da mulher no mundo contemporâneo, fazem parte de uma discussão específica relativa à mulher e à velhice.

  16. Using poison center exposure calls to predict methadone poisoning deaths.

    Directory of Open Access Journals (Sweden)

    Nabarun Dasgupta

    Full Text Available PURPOSE: There are more drug overdose deaths in the Untied States than motor vehicle fatalities. Yet the US vital statistics reporting system is of limited value because the data are delayed by four years. Poison centers report data within an hour of the event, but previous studies suggested a small proportion of poisoning deaths are reported to poison centers (PC. In an era of improved electronic surveillance capabilities, exposure calls to PCs may be an alternate indicator of trends in overdose mortality. METHODS: We used PC call counts for methadone that were reported to the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS® System in 2006 and 2007. US death certificate data were used to identify deaths due to methadone. Linear regression was used to quantify the relationship of deaths and poison center calls. RESULTS: Compared to decedents, poison center callers tended to be younger, more often female, at home and less likely to require medical attention. A strong association was found with PC calls and methadone mortality (b=0.88, se=0.42, t=9.5, df=1, p<0.0001, R(2 =0.77. These findings were robust to large changes in a sensitivity analysis assessing the impact of underreporting of methadone overdose deaths. CONCLUSIONS: Our results suggest that calls to poison centers for methadone are correlated with poisoning mortality as identified on death certificates. Calls received by poison centers may be used for timely surveillance of mortality due to methadone. In the midst of the prescription opioid overdose epidemic, electronic surveillance tools that report in real-time are powerful public health tools.

  19. Análise das Barreiras que Dificultam a Transformação do Agricultor Familiar em Empreendedor Rural no Contexto Brasileiro

    Directory of Open Access Journals (Sweden)

    Patricia Amelia Tomei

    2014-09-01

    Full Text Available Apesar da relevância da agricultura familiar, até meados da década de 90, os agricultores brasileiros tinham pouco acesso ao crédito e as políticas públicas existentes muitas vezes não atendiam aos anseios desta população. Em 1996, o governo brasileiro criou o PRONAF – Programa Nacional da Agricultura Familiar, que apesar de inúmeras qualidades, enfrenta desafios relacionados a aspectos sócio-culturais e características psicossociais dos agricultores, que nem sempre conseguem incorporar os comportamentos necessários para serem empreendedores num setor que cada vez mais demanda por inovação e desenvolvimento. Este é o principal objetivo deste trabalho: relacionar a questão do empreendedorismo rural e da agricultura familiar à questão da inovação e do desenvolvimento a partir da análise das barreiras enfrentadas pelo agricultor familiar (AF que dificultam ou impedem sua transformação em empreendedor rural (ER. Para o estudo destes dois grupos, fizemos entrevistas em profundidade e aplicamos um questionário estruturado a agricultores indicados por uma cooperativa de crédito rural do Sul do Brasil. A análise evidenciou que as barreiras para o empreendedorismo rural estavam associadas à ausência de  liderança e capacidade de assumir riscos; e enfatizou a importância da família, das redes sociais e da educação formal no desenvolvimento do AF. Concluímos que os AF não podem ser considerados como potenciais empreendedores schumpeterianos típicos, mas, alguns pontos são importantes para a implementação de políticas públicas: uma abordagem contingencial; direcionamento de recursos para perfis mais empreendedores; favorecer as avaliações objetivas e subjetivas dos resultados da alocação de recursos, desenvolver incubadoras de negócios, formação e educação gerencial.

  20. Economia social, economia solidária, terceiro setor: do que se trata?

    Lechat, Noëlle Marie Paule

    2002-01-01

    Full Text Available A partir da segunda metade da década de 90, aparece na literatura acadêmica brasileira uma série de novas categorias que poderiámos agrupar sob as apelações de "terceiro setor" e "economia solidária". A pesquisa concentra-se na segunda categoria e tem por objetovo identificar sua origem e a realidade que ela pretende abranger. Neste texto são expostas algumas definições que podem ser encontradas na literatura internacional a respeito de termos como economia social, economia solidária, terceiro setor e outros mais. Deste confronto aparece que os conceitos utilizados no Brasil para estudar o campo da economia solidária tendem a uma certa estreiteza devido à pouca ênfase sobre questões como o resgate histórico anterior aos anos 80, a pluralidade ideológica e o hibridismo econômico, porém demonstram sensibilidade quanto à construção de uma outra cultura econômica de mercado, economia estatal e economia de reciprocidade que a categoria de terceiro setor tende a mascarar. Em vista disto, constata-se a necessidade de repensar esta categoria e de questionar as grandes expectativas assentadas na for mação de uma economia solidária para a transformação da sociedade

    2014-02-01

    Animals emit vocalizations that convey information about external events. Many of these vocalizations, including those emitted in response to predators, also encode information about the individual that produced the call. The relationship between acoustic features of antipredator calls and information relating to signalers (including sex, identity, body size, and social rank) were examined in peafowl (Pavo cristatus). The "bu-girk" antipredator calls of male and female peafowl were recorded and 20 acoustic parameters were automatically extracted from each call. Both the bu and girk elements of the antipredator call were individually distinctive and calls were classified to the correct signaler with over 90% and 70% accuracy in females and males, respectively. Females produced calls with a higher fundamental frequency (F0) than males. In both females and males, body size was negatively correlated with F0. In addition, peahen rank was related to the duration, end mean frequency, and start harmonicity of the bu element. Peafowl antipredator calls contain detailed information about the signaler and can potentially be used by receivers to respond to dangerous situations.

    2018-03-01

    The purpose of this study was to explore the relationship of perceived calling and work engagement in nursing over and above major work environment factors. In all, 351 nurses from various health care institutions completed the survey. Data were collected about the most demanding aspects of nursing, major job resources, the degree to which nursing is perceived as a meaningful calling, work engagement, and main demographic information. Hierarchical linear regression was applied to assess the relation between perceived calling and work engagement, while controlling for demographic and work environment factors, and perceived calling was significantly related to two out of three components of nurses' work engagement. The highest association was found with dedication component, and vigor component was related insignificantly. Results have shown that perceived calling might motivate nurses to engage in their work even in burdensome environment, although possible implications for the occupational well-being of nurses themselves remains unclear.

  10. Call cultures in orang-utans?

    Directory of Open Access Journals (Sweden)

    Serge A Wich

    Full Text Available BACKGROUND: Several studies suggested great ape cultures, arguing that human cumulative culture presumably evolved from such a foundation. These focused on conspicuous behaviours, and showed rich geographic variation, which could not be attributed to known ecological or genetic differences. Although geographic variation within call types (accents has previously been reported for orang-utans and other primate species, we examine geographic variation in the presence/absence of discrete call types (dialects. Because orang-utans have been shown to have geographic variation that is not completely explicable by genetic or ecological factors we hypothesized that this will be similar in the call domain and predict that discrete call type variation between populations will be found. METHODOLOGY/PRINCIPAL FINDINGS: We examined long-term behavioural data from five orang-utan populations and collected fecal samples for genetic analyses. We show that there is geographic variation in the presence of discrete types of calls. In exactly the same behavioural context (nest building and infant retrieval, individuals in different wild populations customarily emit either qualitatively different calls or calls in some but not in others. By comparing patterns in call-type and genetic similarity, we suggest that the observed variation is not likely to be explained by genetic or ecological differences. CONCLUSION/SIGNIFICANCE: These results are consistent with the potential presence of 'call cultures' and suggest that wild orang-utans possess the ability to invent arbitrary calls, which spread through social learning. These findings differ substantially from those that have been reported for primates before. First, the results reported here are on dialect and not on accent. Second, this study presents cases of production learning whereas most primate studies on vocal learning were cases of contextual learning. We conclude with speculating on how these findings might

    The lunar hypothesis, that is, the notion that lunar phases can directly affect human behavior, was tested by time-series analysis of 4,575 crisis center telephone calls (all calls recorded for a 6-month interval). As expected, the lunar hypothesis was not supported. The 28-day lunar cycle accounted for less than 1% of the variance of the frequency of crisis center calls. Also, as hypothesized from an attribution theory framework, crisis center workers reported significantly greater belief in lunar effects than a non-crisis-center-worker comparison group.

  2. Perceiving a calling, living a calling, and job satisfaction: testing a moderated, multiple mediator model.

    2012-01-01

    The current study examined the relation between perceiving a calling, living a calling, and job satisfaction among a diverse group of employed adults who completed an online survey (N = 201). Perceiving a calling and living a calling were positively correlated with career commitment, work meaning, and job satisfaction. Living a calling moderated the relations of perceiving a calling with career commitment and work meaning, such that these relations were more robust for those with a stronger sense they were living their calling. Additionally, a moderated, multiple mediator model was run to examine the mediating role of career commitment and work meaning in the relation of perceiving a calling and job satisfaction, while accounting for the moderating role of living a calling. Results indicated that work meaning and career commitment fully mediated the relation between perceiving a calling and job satisfaction. However, the indirect effects of work meaning and career commitment were only significant for individuals with high levels of living a calling, indicating the importance of living a calling in the link between perceiving a calling and job satisfaction. Implications for research and practice are discussed. (c) 2012 APA, all rights reserved.

    To describe symptom type and reporting patterns found in spontaneously initiated telephone calls placed to an ambulatory cancer center practice. Retrospective, descriptive. Adult hematology oncology cancer center. 563 individuals with a wide range of oncology diagnoses who initiated 1,229 telephone calls to report symptoms. Raw data were extracted from telephone forms using a data collection sheet with 23 variables obtained for each phone call, using pre-established coding criteria. A literature-based, investigator-developed instrument was used for the coding criteria and selection of which variables to extract. Symptom reporting, telephone calls, pain, and symptoms. A total of 2,378 symptoms were reported by telephone during the four months. At least 10% of the sample reported pain (38%), fatigue (16%), nausea (16%), swelling (12%), diarrhea (12%), dyspnea (10%), and anorexia (10%). The modal response was to call only one time and to report only one symptom (55%). Pain emerged as the symptom that most often prompted an individual to pick up the telephone and call. Although variation was seen in symptom reporting, an interesting pattern emerged with an individual reporting on a solitary symptom in a single telephone call. The emergence of pain as the primary symptom reported by telephone prompted educational efforts for both in-person clinic visit management of pain and prioritizing nursing education and protocol management of pain reported by telephone. Report of symptoms by telephone can provide nurses unique insight into patient-centered needs. Although pain has been an important focus of education and research for decades, it remains a priority for individuals with cancer. A wide range in symptom reporting by telephone was evident.

Na disjunção entre elas, os muedenses relacionaram-se criticamente com o processo de democratização em curso, articulando a sua própria visão acerca do funcionamento do poder no mundo que habitam. Equiparações à primeira vista paradoxais - como entre descentralização democrática e abandono por parte do Estado, entre liberdade individual e perigo colectivo de feitiçaria, ou entre democracia e carnificina - constituíram, afinal, formas em última instância democráticas de avaliação e de crítica às transformações ocorridas e às formas como o poder é exercido no novo contexto de capitalismo neoliberal.The language of power spoken by the inhabitants of the Mueda plateau in the course of the neoliberal transformation of Mozambican political and economic life is substantially different to the language spoken by democratic reformers, despite the commonalities and internal variations in both languages. In the rift between the languages, the Muedans adopt a critical stance towards the current process of democratization, articulating their own vision of how power operates in their world. Equivalences which are at first sight paradoxical - such as equating democratic decentralization with abandonment by the state, individual freedom with the collective danger of witchcraft, and democracy with carnage - were ultimately democratic ways of evaluating and criticizing the changes taking place and the ways in which power is used in the new context of neoliberal capitalism.

    Some octopamine agonists were found to suppress the calling behavior of the stored product Indian meal moth, Plodia interpunctella. Compounds were screened using a calling behavior bioassay using female P. interpunctella. Four active derivatives, with inhibitory activity at the nanomolar range, were identified in order of decreasing activity: 2-(1-phenylethylamino)-2-oxazoline > 2-(2-ethyl,6-methylanilino)oxazolidine > 2-(2-methyl benzylamino)-2-thiazoline > 2-(2,6-diethylanilino)thiazolidine. Three-dimensional pharmacophore hypotheses were built from a set of 15 compounds. Among the ten common-featured models generated by the program Catalyst/HipHop, a hypothesis including a hydrogen-bond acceptor lipid, a hydrophobic aromatic and two hydrophobic aliphatic features was considered to be essential for inhibitory activity in the calling behavior. Active compounds mapped well onto all the hydrogen-bond acceptor lipid, hydrophobic aromatic and hydrophobic aliphatic features of the hypothesis. On the other hand, less active compounds were shown not to achieve the energetically favorable conformation that is found in the active molecules in order to fit the 3D common-feature pharmacophore models. The present studies demonstrate that inhibition of calling behavior is via an octopamine receptor.

  8. Relabeling the Medications We Call Antidepressants

    Directory of Open Access Journals (Sweden)

    David Antonuccio

    2012-01-01

    Full Text Available This paper raises the question about whether the data on the medications we call antidepressants justify the label of antidepressant. The authors argue that a true antidepressant should be clearly superior to placebo, should offer a risk/benefit balance that exceeds that of alternative treatments, should not increase suicidality, should not increase anxiety and agitation, should not interfere with sexual functioning, and should not increase depression chronicity. Unfortunately, these medications appear to fall short on all of these dimensions. Many of the “side effects” of these medications have larger effect sizes than the antidepressant effect size. To call these medications antidepressants may make sense from a marketing standpoint but may be misleading from a scientific perspective. Consumers deserve a label that more accurately reflects the data on the largest effects and helps them understand the range of effects from these medications. In other words, it may make just as much sense to call these medications antiaphrodisiacs as antidepressants because the negative effects on libido and sexual functioning are so common. It can be argued that a misleading label may interfere with our commitment to informed consent. Therefore, it may be time to stop calling these medications antidepressants.

    Full Text Available Treatment with dexamethasone (DMS in the early phases of the experimental Schistosoma mansoni infection causes an indirect effect on the cercaria-schistosomulum transformation process. This is observed when naive albino mice are treated with that drug (50 mg/Kg, subcutaneously and infected intraperitonealy 01 hour later with about 500 S. mansoni cercariae (LE strain. An inhibition in the host cell adhesion to the larvae, with a simultaneous delay in the cercaria-schistosomulum transformation, is observed. This effect is probably due to a blockade of the neutrophil migration to the peritoneal cavity of mice, by an impairment of the release of chemotactic substances. Such delay probably favors the killing of S. mansoni larvae, still in the transformation process, by the vertebrate host defenses, as the complement system.O tratamento com dexametasona (DMS nas fases iniciais da infecção experimental com S. mansoni leva a um efeito indireto sobre o processo de transformação da cercária em esquistossômulo, quando camundongos isentos de infecção são tratados com esta droga (50 mg/ kg, subcutâneamente e, 01 hora depois, são infectados intraperitonealmente com cerca de 500 cercárias de S. mansoni (cepa LE. Foi observada uma significativa redução na adesão de células do hospedeiro às larvas, com um atraso simultâneo no processo de transformação das cercárias em esquistossômulos. Este efeito é, provavelmente, devido a um bloqueio inespecifícico da migração neutrofilica para a cavidade peritoneal, através de um bloqueio da liberação de substâncias quimio-táticas. Tal atraso pode permitir a morte das larvas de S. mansoni (ainda em processo de transformação pelas defesas do hospedeiro vertebrado, como o sistema do complemento.

    In Bratislava, one year ago, exactly in April 28, the privatization deal of a 66% stake in Slovenske elektrarne (SE) was finally closed. The Slovak government and the Italian company ENEL signed final documents and ENEL thus definitely entered into SE. In May 2006, Miroslav Pikus, a former CEO, was replaced by Marco Arcelli, who, as a regional manager for Slovakia, had been preparing the entry of ENEL into SE since March 2005. Not only did he sometimes cook for us, in his 'kitchen' but also there were prepared 160 investment projects, e.g the improvement of nuclear safety and resistance of the Bohunice power plant, electricity sale through the so-called 'virtual power plant', ensuring a non-attended operation in hydro power plants, reconstruction and modernization of the Orava and Dobsina hydro power plants.

      PALAVRAS-CHAVE: consumo; marketing; publicidade; segmentação; semiótica.     ABSTRACT The immense transformations that Brazil has undergone in the last decade - connected, as it is known, to the consumption - have brought great challenges to marketing and advertising. This paper intends to discuss, from an interpretive look, how this new socio-cultural panorama has manifested itself in terms of sign in the Brazilian advertising, subverting basic issues such as demographic segmentation and positioning. From the analytical perspective of semiotics along with the theoretical references of the anthropology of consumption, we examine how the imaginary of the elite and the popular unfold in the current Brazilian advertising, delimiting two worlds that complete one another, between which transitions are allowed and from which maybe we can understand the dynamics of the contemporary consumption.   KEYWORDS: consumption; marketing; advertising; segmentation; semiotics.     RESUMEN Las inmensas transformaciones que Brasil ha experimentado en la última década - conectadas, como se sabe, al consumo - han traído grandes desafíos a la comercialización y por lo tanto a la publicidad.

  7. Eight Leadership Emergency Codes Worth Calling.

    Science.gov (United States)

    Freed, David H

    Hospitals have a contemporary opportunity to change themselves before attempting to transform the larger US health care system. However, actually implementing change is much more easily described than accomplished in practice. This article calls out 8 dysfunctional behaviors that compromise professional standards at the ground level of the hospital. The construct of calling a code when one witnesses such behaviors is intended to make it safe for leaders to "See something, say something" and confront them in real time. The coordinated continuum of services that health care reform seeks to attain will not emerge until individual hospital organizations prepare themselves to operate better in their own spaces and the ones that immediately surround them.

Assim, um envolvimento com estudos críticos transmodernos do turismo e atividades turísticas de esperança nos dão um peso político enorme para apontar a função e autoridade do turismo para possivelmente mudar o mundo para melhor e ajudá-lo no desejo de uma economia e sociedade global mais consciente. Ao fazer isso, nós podemos, finalmente, penetrar os discursos públicos e mudar a sua perspectiva dominante do turismo como sendo nada mais que uma atividade fútil de lazer ou mais uma forma de desenvolvimento econ

    Ghislieri, Chiara; Ricotta, Simona; Colombo, Lara

    2012-01-01

    The working environment of call centers, which have seen a significant growth in recent years, has been the subject of several studies aiming at understanding its specific dynamics, with particular attention to the possible causes of stress and discomfort. Despite the fact that the work-family conflict is considered a source of stress responsible for undermining workers' well-being, and as such has been explored in many work environments, there is still very little research specific to call centers. This study had the following aims: to explore work-family conflict perceived by call-center operators taking account of any differences related to respondents'professional and personal characteristics; to understand which demands and resources can have an impact on work-family conflict in this context. The study was carried out on a sample of 898 call center operators in a telecommunications company through the administration of a self-reporting questionnaire. Data analysis included: t-test, one-way analysis of variance, linear correlations and multiple regressions. A higher perception of work-family conflict among workers having a full-time contract was observed compared to those having part-time contracts. Multiple regression analysis identified as sources of influence on work-family conflict: emotional dissonance, uneasiness due customer dissatisfaction, workload, avoidance coping and working hours. Work-family conflict in the context studied is not particularly critical: it is in part influenced by professional and personal characteristics of respondents and primarily caused by work demands. Managerial implications are discussed, especially referred to training activities.

    2014-04-01

    Full Text Available Este trabalho apresenta uma metodologia voltada para mensurar a velocidade de um corpo rígido em movimento, tendo como ponto de partida, uma sequência de imagens obtidas por meio de uma filmadora digital. No processo de mensuração da velocidade, na etapa de identificação dos corpos em movimento, é utilizada uma técnica de segmentação baseada na média temporal dos valores de cada pixel registrados em N quadros de imagens consecutivos, em que, após a identificação desses corpos, é realizada a transformação dos pontos no plano imagem para o espaço objeto, por meio do modelo matemático definido como funções racionais. Conhecendo-se as coordenadas dos pontos no espaço objeto, a velocidade de deslocamento do corpo pode ser calculada, através do intervalo de tempo obtido pela quantidade de quadros que a câmara captura por segundo. Para validar a metodologia proposta foi realizado um experimento que contou com a utilização de um aparelho denominado trilho de ar, cinco sensores fotoelétricos dispersos sobre o mesmo com distancias conhecidas entre si e um cronômetro ligado aos sensores. No momento em que um corpo em movimento passa por um sensor, o cronômetro é paralisado e com isso, se tem a distância percorrida pelo corpo entre cada sensor e, quanto tempo foi necessário para percorrer cada uma dessas distâncias. Com esses dados em mãos é realizada uma comparação dos resultados obtidos por meio da análise de sequência de imagens com os resultados obtidos através dos cronômetros e dos sensores fotoelétricos.

    Full Text Available A reflexão se pauta na recuperação do trabalho como catego-ria chave da compreensão da história, e indica limites e possibilidadesda ação sindical em um contexto de restrição de espaços públicos e ações coletivas. Ao considerar a importância do espaço público parase compreender a dinâmica do movimento sindical de trabalhadoreshoje, busca enfatizar o fato de tal movimento ser um tipo de ação coletiva e que não pode ser pensado apenas no espaço do “mundo do trabalho” ou no espaço institucional das relações profissionais. A ampliação do campo de ação sindical torna-se interessante, para além do que se passa na esfera do trabalho e das empresas, pois a ação tradicional do sindicalismo mostra-se insuficiente para enfrentar a multiplicidade de terrenos, disputas e lutas que devem ser conduzidas fora do trabalho, as quais são tão numerosas e complexas que nenhuma organização pode pretender assumi-las sozinha. A constituição de espaços públicosé uma estratégia que pode reinventar o debate, descentrando-o da oposição estatal-privado, tão em voga e conveniente à operação ideológica liberal.

  18. Selenium Se and tellurium Te

    International Nuclear Information System (INIS)

    1978-01-01

    The basic methods for determining selenium and tellurium in various objects are presented. The bichromatometric determination of Te in cadmium, zinc and mercury tellurides is based on oxidation of Te(4) to (6) in H 2 SO 4 with potassium bichromate. In steels, Te is determined photometrically with the aid of KI. The determination is hindered by Fe(3), Cu(2), Bi(3) and Se(4) ions, which must be separated. The extraction-photometric determination of Te in native sulfur is carried out with the aid of 5-mercapto-3-(naphthyl-2)-1,3,4-thiadiazolthione-2 (pH=4.8-5.0). The dyed complex is readily extracted with chloroform and benzene. The spectrophotometric determination of Te in selenium is performed with the aid of 3,5-diphenylpyrazoline-1-dithiocarbamate of sodium. Te is determined in commercial indium, arsenic and their semiconductor compounds photometrically with the aid of copper diethyldithiocarbamate. The method permits determining 5x10 -5 % Te in a weighed amount of 0.5 g. The chloride complex of Te(4) with diantipyriodolpropylmethane is quantitatively extracted with dichloroethane from hydrochloric acid solutions. Thus, any amounts of Te can be separated from Se and determined photometrically. The extraction-photometric determination of Te in commercial lead and bismuth is carried out with the aid of pyrazolone derivatives, in commercial copper with the aid of diantipyridolpropylmethane, and in ores (more than 0.01% Te) with the aid of bismuthol 2. Also described is the extraction-polarographic determination of Te in sulfide ores

    Selenium biotransformation by lactic acid bacteria during the preparation of Se-enriched yogurt was evaluated. The study focused on the distribution of selenium in the aqueous soluble protein fraction and the detection of selenoamino acids. Screening of selenium in Tris-buffer-urea soluble fraction was carried out by sodium dodecyl sulphate polyacrylamide gel electrophoresis after pre-fractionating with asymmetric field flow fractionation using inductively coupled plasma-mass spectrometry as the detector. Selenium-containing fractions were identified by peptide mapping using nano LC-ESI/LTQMS. Proteins such as thioredoxin, glutaredoxin, albumin, β-lactoglobulin, and lactoperoxidase were identified in the selenium-containing fraction. All these proteins were detected in both the control and the selenium-enriched yogurt except chaperones, which were only detected in the control samples. Chaperones are heat-shock proteins expressed in response to elevated temperature or other cellular stresses. Selenium may have an effect on chaperones expression in Lactobacillus. For the amino acids analysis, selenocysteine was the primary seleno-containing species. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Modern technologies not only provide a variety of communication modes (e.g., texting, cell phone conversation, and online instant messaging), but also detailed electronic traces of these communications between individuals. These electronic traces indicate that the interactions occur in temporal bursts. Here, we study intercall duration of communications of the 100,000 most active cell phone users of a Chinese mobile phone operator. We confirm that the intercall durations follow a power-law distribution with an exponential cutoff at the population level but find differences when focusing on individual users. We apply statistical tests at the individual level and find that the intercall durations follow a power-law distribution for only 3,460 individuals (3.46%). The intercall durations for the majority (73.34%) follow a Weibull distribution. We quantify individual users using three measures: out-degree, percentage of outgoing calls, and communication diversity. We find that the cell phone users with a power-law duration distribution fall into three anomalous clusters: robot-based callers, telecom fraud, and telephone sales. This information is of interest to both academics and practitioners, mobile telecom operators in particular. In contrast, the individual users with a Weibull duration distribution form the fourth cluster of ordinary cell phone users. We also discover more information about the calling patterns of these four clusters (e.g., the probability that a user will call the c(r)-th most contact and the probability distribution of burst sizes). Our findings may enable a more detailed analysis of the huge body of data contained in the logs of massive users.

    Full Text Available O presente artigo apresenta pesquisa que estuda as consequências perceptíveis do processo de penetração dos fundos financeiros na educação superior no Brasil e, posteriormente, a emissão de ações de instituições de ensino diretamente na bolsa de valores. Entre os resultados observados encontra-se o rápido crescimento das instituições que adotaram tal estratégia. A forma mais visível desse crescimento é a compra de outras instituições e seu aperfeiçoamento, por meio da implantação de uma gestão mais profissionalizada. Tal processo tem propiciado o crescimento acelerado de algumas instituições, generalizando a educação como uma mercadoria, assim como a tendencial oligopolização da oferta. Conclui-se afirmando que é cabível falar-se em uma financeirização da educação, posto que é o setor financeiro que assume a hegemonia na educação privada no país.This paper presents a research on the noticeable consequences of the supply of private equities and venture capital in Brazilian Higher Education and of the subsequent going public of many teaching institutions. These are growing fast, mainly through the purchase of other schools, whose administration is professionalized. Such process has generalized both education as a commodity and the oligopolization of provision. It is thus possible to conclude that education has been financialized, since private education is nowadays hegemonic in Brazil.

    We would like to continue the series of special issue or maybe edit a book on this topic. To complete the formerly edited special issues we would like to link natural hazards research to cultural heritage research. We see a way of doing this connected to "integrated conservation", which sees the involvment of urban planning in conservation, as well as the (urban) sociology, the integration of the user, the participatism. We further call for investigation of GIS applications for the investigation of natural hazards' impact in this field. We are open for further ideas and wait for you at the Splinter meeting.

    In March 2016 the Joint Photographic Experts Group (JPEG), formally known as ISO/IEC SC29 WG1, issued a call for proposals soliciting compression technologies for a low-latency, lightweight and visually transparent video compression scheme. Within the JPEG family of standards, this scheme was denominated JPEG XS. The subjective evaluation of visually lossless compressed video sequences at high resolutions and bit depths poses particular challenges. This paper describes the adopted procedures, the subjective evaluation setup, the evaluation process and summarizes the obtained results which were achieved in the context of the JPEG XS standardization process.

    Full Text Available Weak-head normalization is inconsistent with functional extensionality in the call-by-name λ-calculus. We explore this problem from a new angle via the conflict between extensionality and effects. Leveraging ideas from work on the λ-calculus with control, we derive and justify alternative operational semantics and a sequence of abstract machines for performing head reduction. Head reduction avoids the problems with weak-head reduction and extensionality, while our operational semantics and associated abstract machines show us how to retain weak-head reduction's ease of implementation.

No entanto, argumenta-se aqui que uma nova hegemonia tem-se formado por meio da distinção de uma nova agenda tecnocientífica global. Esta agenda se instala em função da controvérsia das mudanças climáticas, que exigirá, neste século, uma corrida pela  produção de um novo paradigma tecnológico, “produtivo”, mas “sustentável”.

  9. Interactionability in Computer Game: Call of Duty

    Full Text Available For a long time communication theorists have criticized public media for being unilateral. What they prescript is to transform pattern of communication into bilateral one; in other words, to make media interactional. Telephone is the first fully interactional, however, there was a long road to the contemporary communication and information media which are highly interactional. Nevertheless, not all the modern media are equally interactional. Therefore, it is necessary to evaluate levels of interactionability in modern media and strength them. As other concepts in communication, interaction has different definitions, implying various aspects of the audience-media relation. And this feature of multi-dimensionality is to be considered. Quistis (2002 suggests a model in which all the technical, social, and comprehensive aspects of interaction are inherent. In other words, not only the technical aspect of media, but also audience’s perception plays a key role in the model. Visual-computer games are good instance of interactionability in modern media. However, not all games are equally interactional. Analyzing a well-known computer game “Call of Duty”, this article attempts to study different levels of interactionability. The main question is: how can one offer a pragmatic definition of three dimensions of interactionability to study computer games; and how this features are in Call of Duty applied?

  10. Theology links Christian ministry with God's call.

    O'Connell, L J

    1984-03-01

    Catholic health care ministry originates in and is shaped by the theme of call in the Old and New Testaments. To be specifically Catholic, health professionals and facilities must define their ministries according to the values expressed in this theological tradition. Sponsorship. The opportunity to provide health care enables religious communities to contribute to God's ongoing creation process and to reiterate Christ's call to minister to others. Although health care facility sponsorship thrusts religious communities into the arena of big business, the abandonment of the health care mission could be considered a betrayal of evangelical values. Quality of life. The implicit concern for human dignity that distinguishes Catholic health care facilities should be evident in personalized patient care, just working conditions, and a commitment to healing in the civic community. Stewardship in ethics. The development of business policies and procedures and institutional responses to social change should be carefully considered in light of the Catholic understanding of loving covenant and the Christian way of life. Shared ministry. Health care facilities have played a leading role in implementing the Second Vatican Council's vision of ministry. Sponsoring communities' continued willingness to share responsibilities with laity will be imperative in meeting the health care demands of the future.

Sustenta-se na teoria sociológica articulando três abordagens: do materialismo histórico-dialético sobre o processo de trabalho em saúde e enfermagem; da sociologia das profissões em uma perspectiva crítica; e da filosofia da ciência. A argumentação está organizada considerando aspectos da Enfermagem enquanto disciplina, trabalho e profissão da saúde. Sustenta que a produção do conhecimento deve ser orientada pela finalidade do trabalho de cuidar de seres humanos com carências de saúde e pela defesa das condições necessárias para um fazer seguro e responsável. Conclui que, para fortalecer a Enfermagem, é necessário produzir conhecimentos que fundamentem as ações de cuidado, assim como as lutas políticas em defesa da profissão, do direito universal à saúde e a cuidados seguros e de qualidade.

    . Furthermore, our results concerning the pair structure of the wave functions of the even-spin states in chains of even-even and odd-odd N = Z nuclei in the A 60 - 80 mass region revealed a clear interplay between isovector neutron-proton and like-nucleon pairing correlations. Nevertheless, detailed aspects of these properties are sensitive to the renormalization of the effective interaction in the pairing channels. Taking advantage of our microscopic investigations on the coexistence phenomena in this mass region, which have already past many experimental tests, we address the problem of the structure of the lowest few even-spin positive-parity states in 68 Se. Also we present details of the results obtained using a few slightly different prescriptions for the effective interaction in order to illustrate the above mentioned problems. The theoretical spectrum of 68 Se for even spin positive parity states is compared with the experimental results. (authors)

This history rejects the notion that human societies do not cause significant environmental alterations and analyzes the specific conditions of that recurring interaction. The agroecologic system is one of the most typical cases of the intervention of human activity on natural ecosystems in a complex interaction between indigenous plants, exotic vegetation, fertility of the soil and diverse agricultural practices. The roadmap of these changes is essential to understand history from the view point of the environment.

  1. From nestling calls to fledgling silence: adaptive timing of change in response to aerial alarm calls.

    Science.gov (United States)

    Magrath, Robert D; Platzen, Dirk; Kondo, Junko

    2006-09-22

    Young birds and mammals are extremely vulnerable to predators and so should benefit from responding to parental alarm calls warning of danger. However, young often respond differently from adults. This difference may reflect: (i) an imperfect stage in the gradual development of adult behaviour or (ii) an adaptation to different vulnerability. Altricial birds provide an excellent model to test for adaptive changes with age in response to alarm calls, because fledglings are vulnerable to a different range of predators than nestlings. For example, a flying hawk is irrelevant to a nestling in a enclosed nest, but is dangerous to that individual once it has left the nest, so we predict that young develop a response to aerial alarm calls to coincide with fledging. Supporting our prediction, recently fledged white-browed scrubwrens, Sericornis frontalis, fell silent immediately after playback of their parents' aerial alarm call, whereas nestlings continued to calling despite hearing the playback. Young scrubwrens are therefore exquisitely adapted to the changing risks faced during development.

    Full Text Available Motivated by call center practice, we study the optimal staffing of many-server queues with impatient and repeat-calling customers. A call center is modeled as an M/M/s+M queue, which is developed to a behavioral queuing model in which customers come and go based on their satisfaction with waiting time. We explicitly take into account customer repeat behavior, which implies that satisfied customers might return and have an impact on the arrival rate. Optimality is defined as the number of agents that maximize revenues net of staffing costs, and we account for the characteristic that revenues are a direct function of staffing. Finally, we use numerical experiments to make certain comparisons with traditional models that do not consider customer repeat behavior. Furthermore, we indicate how managers might allocate staffing optimally with various customer behavior mechanisms.

    Full Text Available Call frequency and movements of the gecko Hemidactylus frenatus were studied in Punta Morales, Costa Rica from April 1999 through May 2000. Call activity of H. frenatus was positively related to air temperature at night and throughout the year. Higher activity was at dusk, dawn, and during the hottest months. Call frequency was related with gecko abundance per month, although not during the night. More males and females had a regenerated tail compared to juveniles, the last ones could have it complete or regenerated. Females moved longer distances than males and juveniles. Adults were found higher on walls. Males and females were recaptured more times than juveniles, and the period of time between their recaptures was longer. Members of this population do not seem to be as aggressive to other geckos as mentioned in the literature. Rev. Biol. Trop. 54 (4: 1125-1130. Epub 2006 Dec. 15Estudié la frecuencia de canto y el desplazamiento de la lagartija Hemidactylus frenatus en Punta Morales, CostaRica. La frecuencia de canto se corelaciona positivamente con la temperatura ambiental durante la noche y con la temperatura a lo largo del año. La mayor actividad fue al anochecer, al amanecer y durante los meses más calurosos. La abundancia mensual de lagartijas se relacionó con la frecuencia de canto, no así la abundancia por noche. Las colas regeneradas son más frecuentes en hembras y machos que en las lagartijas jóvenes. Las hembras se desplazaron mayores distancias que machos y jóvenes. Los adultos se encontraban más alto en las paredes de los edificios. Los machos y hembras se recapturaron más veces que los jóvenes, y el tiempo entre recapturas fue mayor. Esta población no parece ser tan agresiva como se menciona en la literatura

    Open-source software (OSS) encourages computer programmers to reuse software components written by others. In evolutionary bioinformatics, OSS comes in a broad range of programming languages, including C/C++, Perl, Python, Ruby, Java, and R. To avoid writing the same functionality multiple times for different languages, it is possible to share components by bridging computer languages and Bio* projects, such as BioPerl, Biopython, BioRuby, BioJava, and R/Bioconductor. In this chapter, we compare the two principal approaches for sharing software between different programming languages: either by remote procedure call (RPC) or by sharing a local call stack. RPC provides a language-independent protocol over a network interface; examples are RSOAP and Rserve. The local call stack provides a between-language mapping not over the network interface, but directly in computer memory; examples are R bindings, RPy, and languages sharing the Java Virtual Machine stack. This functionality provides strategies for sharing of software between Bio* projects, which can be exploited more often. Here, we present cross-language examples for sequence translation, and measure throughput of the different options. We compare calling into R through native R, RSOAP, Rserve, and RPy interfaces, with the performance of native BioPerl, Biopython, BioJava, and BioRuby implementations, and with call stack bindings to BioJava and the European Molecular Biology Open Software Suite. In general, call stack approaches outperform native Bio* implementations and these, in turn, outperform RPC-based approaches. To test and compare strategies, we provide a downloadable BioNode image with all examples, tools, and libraries included. The BioNode image can be run on VirtualBox-supported operating systems, including Windows, OSX, and Linux.

A pesquisa foi desenvolvida junto a agricultores tradicionais moradores de duas microbacias hidrográficas do município de Biguaçu-SC. A unidade amostral foi a propriedade onde reside o informante-chave, selecionado via Bola-de-Neve. Foram conduzidas entrevistas semiestruturadas, observações participante e turnês-guiadas para coleta de dados. A análise de dados se deu por meio do software Atlas.ti, de estatística descritiva e análise multivariada de Componentes Principais. Os dados foram interpretados com base na linha histórica de ocorrência. A pesquisa diagnosticou que o manejo realizado pela população local se fundamenta na condução periódica de cultivos agrícolas e florestais, num sistema de rotação com períodos de pousio. As principais culturas agrícolas utilizadas eram a mandioca, a banana, o milho, o café e a cana-de-açúcar, mas atualmente apenas a mandioca tem forte expressão. Para todas as fases de desenvolvimento do manejo os agricultores apresentam conhecimentos específicos de leitura da paisagem e da dinâmica florestal. Mudanças nas políticas agrícolas e gestão das florestas nativas têm afetado diretamente o sistema de roça itinerante nas microbacias estudadas. A população local apresenta relação intrínseca com os recursos florestais nativos devendo ter seu modo de vida respeitado e seu sistema tradicional valorizado.

  9. After four months new privatisation committee in SE

    2003-01-01

    In spite of a delay the Minister of Economy of the Slovak Republic wants to meet the schedule set by Government. In middle of September 2002 six prospect submitted their tender offers for entering Slovenske elektrarne (SE), a.s, Bratislava. Representative of privatisation advisor of SE, PricewaterhouseCoopers, Peter Mitka told TREND that he was in contact with the investors but they were waiting for a signal from official authorities about the current state of the tender. And they have been waiting for four months. Only last week a new privatisation commission started dealing with the offers. In spite of these facts Minister of Economy, Robert Nemcsics does not consider the process slow and said that the Ministry would use all its efforts to adhere to the original privatisation schedule prepared by the former government. He further added that everything would depend on the offers submitted. Investors are not interest in SE as a whole but only in its parts. Several members of the committee do not agree with the privatisation and restructuring principles set by the government including a split of SE to conventional and nuclear parts. One of the opponents is the former manager of SE Tibor Mikus (HZDS) - representative of the Parliament or Vladimir Mojs representative of Slovak Energeticists Unions. This put a brake on the tender and changes in the management of SE as well. Privatisation Agency FNM still has not decided upon calling a Extraordinary General Meeting of SE that would elect new bodies. Spokeswoman of FNM, Tatjana Lesajova claims that the Fund is still missing a legal analysis that would review the possibility of changing SE's Articles of Association so that the Board of Directors could be assigned based on a tender (proposal of the Ministry). Members of SE Privatisation Committee: Eva Simkova - Secretary of State, Ministry of Economy SR; Laszlo Pomothy - Secretary of State, Ministry of Economy SR; Henrich Herceg - Advisor to the Minister of Economy SR

    Cholangiocarcinoma (CC) arising from the large intrahepatic bile ducts and extrahepatic hilar bile ducts share clinicopathological features and have been called hilar and perihilar CC as a group. However, "hilar and perihilar CC" are also used to refer exclusively to the intrahepatic hilar type CC or, more commonly, the extrahepatic hilar CC. Grossly, a major distinction can be made between papillary and non-papillary tumors. Histologically, most hilar CCs are well to moderately differentiated conventional type (biliary) carcinomas. Immunohistochemically, CK7, CK20, CEA and MUC1 are normally expressed, being MUC2 positive in less than 50% of cases. Two main premalignant lesions are known: biliary intraepithelial neoplasia (BilIN) and intraductal papillary neoplasm of the biliary tract (IPNB). IPNB includes the lesions previously named biliary papillomatosis and papillary carcinoma. A series of 29 resected hilar CC from our archives is reviewed. Most (82.8%) were conventional type adenocarcinomas, mostly well to moderately differentiated, although with a broad morphological spectrum; three cases exhibited a poorly differentiated cell component resembling signet ring cells. IPNB was observed in 5 (17.2%), four of them with an associated invasive carcinoma. A clear cell type carcinoma, an adenosquamous carcinoma and two gastric foveolar type carcinomas were observed.

    Intimate partner violence (IPV) is a global public health and criminal justice concern with significant impacts; especially high rates are seen among rural Hispanic American (HA) communities, the fastest growing population in the United States. They experience additional barriers to care including extreme poverty, lesser education, gender norms, and language and immigration issues. A systematic literature review was conducted using Cooper's framework to identify evidence supporting associations between interventions and prevention, reduction, and elimination of IPV among rural HA women. Searches conducted on databases including CINAHL, PubMed, Medline, Women's Studies International, MedicLatina, and JSTOR used the MeSH terms Hispanic Americans (Latino/a and Hispanic), domestic violence, and intimate partner violence. Selected studies were published between January 1, 2000, and January 1, 2014. Of the 617 yielded articles, only 6 met the inclusion criteria. Of these, none closely examined rurality or provided valid and reliable measures of outcomes, instead reporting program descriptions and suggested interventions. We identify key findings to guide program, screening, and tool development. Our study identifies a gap in knowledge, research, and effective practices and issues a call for action to create evidence-based tools to prevent, reduce, and eliminate IPV in these underserved populations.

    2005-01-01

    What happened? A CERN colleague, complaining of pains that might indicate serious heart problem, went to the ?infirmary' on the Prévessin site for medical aid. He was unaware that the ?infirmary' was in fact no such thing, but the office of the French contractors' medical practitioner, and, on top of that, it was closed. He therefore took his own car and went to the CERN Fire Station on the Meyrin Site (Building 65). The firemen and the CERN medical team took care of him and requested helicopter transport to the Geneva cantonal hospital, where he responded well to medical treatment. What do we learn from this event? You must call the CERN internal number 74444 in the event of serious and acute illness, and do not have to present yourself in person or get somebody to go with you. This number is not reserved exclusively for accident, pollution, fire etc. The Firemen can prodice professional assistance at all times as required: first aid on the spot, amulance transport and medical assistance as necessary. ...

    Twenty-four patients with unexplained somatic complaints were subjected to a thorough somatic examination. Only when the examination proved negative was the patient entered into the study. The patients were clinically appraised according to criteria given in DSM-III. Generalized anxiety disorder (GAD) was diagnosed in 12, somatization disorder (SD) in 8, and hypochondriasis in 4 patients. Seventeen of the 24 patients agreed to participate in biochemical investigations including a TRH load, a dexamethasone test, and a determination of the monoamine metabolites 5-HIAA and HVA in cerebrospinal fluid (CSF). A normal TSH increase and a normal suppression of cortisol were registered. The HVA values correlated significantly with the 5-HIAA values as well as with the alexithymia scores. Concerning alexithymia and maturity level, no difference as to social class was found. The patients filled in a Zung depression chart. The Zung scale and the 5-HIAA values were both inconsistent with depressive illness. In so-called hypochondriasis a long-term relationship, including selected somatic and biochemical examinations and thorough information, was crucial in abating the patient's distrust and thus the need for health care.

    Toothed whales rely on sound to echolocate prey and communicate with conspecifics, but little is known about how extreme pressure affects pneumatic sound production in deep-diving species with a limited air supply. The short-finned pilot whale (Globicephala macrorhynchus) is a highly social species among the deep-diving toothed whales, in which individuals socialize at the surface but leave their social group in pursuit of prey at depths of up to 1000 m. To investigate if these animals communicate acoustically at depth and test whether hydrostatic pressure affects communication signals, acoustic DTAGs logging sound, depth and orientation were attached to 12 pilot whales. Tagged whales produced tonal calls during deep foraging dives at depths of up to 800 m. Mean call output and duration decreased with depth despite the increased distance to conspecifics at the surface. This shows that the energy content of calls is lower at depths where lungs are collapsed and where the air volume available for sound generation is limited by ambient pressure. Frequency content was unaffected, providing a possible cue for group or species identification of diving whales. Social calls may be important to maintain social ties for foraging animals, but may be impacted adversely by vessel noise.

Dentre os primeiros elementos se situam a permanência de um mesmo grupo de nações de economia avançada no pelotão das potências dominantes que formulam e determinam a agenda política internacional, bem como a importância do poderio tecnológico e industrial para apoiar a projeção estratégica e militar dessas potências; dentre as rupturas podem ser citadas a derrota dos emergentes, em especial Japão e Alemanha, que desafiaram a ordem política e econômica mundial mediante tentativas de projeção imperial que destoavam dos esforços de interdependência global que estavam sendo construídos pelas principais economias de mercado, todas de orientação política liberal democrática. A outra potência emergente no período, a União Soviética, foi relativamente marginal economicamente no período e só projetaria poder, verdadeiramente, no final da Segunda Guerra Mundial.

Essa mudança estrutural da economia brasileira é a motivação para este estudo, cujo objetivo é analisar o efeito da nacionalidade das empresas sobre o fluxo de empregos industrial. Trata-se de um tema sobre o qual há pouca evidência, mesmo para países desenvolvidos, embora não seja raro considerar as empresas estrangeiras como mais 'voláteis' que as empresas domésticas. Usando dados da RAIS e de outras bases e uma amostra de empresas domésticas e estrangeiras, comparamos várias medidas de fluxos de empregos nos dois tipos de empresas. Os resultados apresentados neste trabalho sugerem não haver diferenças significativas nos fluxos de empregos das empresas domésticas e estrangeiras.The late 1990s in Brazil are a period characterized by a large increase in foreign direct investment inflows (and outflows. This process motivates the present study about job flows in domestic and foreign firms. Although foreign firms tend to be considered more 'footloose' than domestic firms, there is very little evidence on this difference, even for developed countries. Using data from RAIS, a large matched employer-employee panel, and other data sets and a sample of foreign and domestic firms, we compare different measures of job flows across the two types of firms. We do not find evidence of job flows' differences between domestic and foreign firms.

    Érica Chulvis do Val Ferreira

    Full Text Available Este artigo tem por objetivo identificar os impactos que mudanças organizacionais oriundas de programa de privatização causam na cultura das empresas e no comportamento dos funcionários. A pesquisa foi realizada em uma empresa do setor de energia privatizada em 1997, com base no método de estudo de caso. A estrutura do estudo de caso consistiu, num primeiro momento, em entrevistas realizadas no nível gerencial, a fim de entender as características e percepções das mudanças empreendidas com a privatização. Posteriormente, foram utilizados questionários fechados para o nível operacional, com o intuito de verificar e estratificar os resultados identificados na primeira etapa. O estudo revelou que as mudanças estratégico-estruturais, culturais e as verificadas nas percepções dos relacionamentos intraorganizacionais foram as que mais impactaram o comportamento dos funcionários. Concluiu-se que as mudanças organizacionais despertaram tanto resistências quanto reações positivas, dependendo da posição hierárquica na organização e da influência de variáveis como: ambiente externo, cultura organizacional, multiculturalismo organizacional, tempo de trabalho na empresa, nacionalidade do empregado e acesso à informação. Este estudo fornece subsídios para uma maior compreensão sobre os impactos dos processos de privatização nas organizações brasileiras, propiciando informações para o gerenciamento de transições corporativas, sejam públicas e/ou privadas.

    Full Text Available The purpose of this paper is to explore the ways in which social perceptions of the Mafia have shifted over time. Initially considered as a Sicilian way of being, as an attitude, the Sicilian Mafia was subsequently viewed as a universal, global, and even religious form of Evil, to be fought in a war in which texts and images were weapons and judicial institutions constituted the battlefield. I will also explore how local powers institutionalised an “anti-Mafia religion”, using as a case-study the Festival of Santa Rosalia in Palermo. In this context, I will discuss the emergence of a new, anti-Mafia iconography and the use of a specific literary genre, that of political hagiography.O objectivo deste artigo é o de explorar os processos através dos quais as percepções sociais sobre a máfia se foram alterando no decurso do tempo. Inicialmente considerada como uma “forma de ser siciliana”, uma atitude, a máfia siciliana foi subsequentemente sendo interpretada como uma expressão universal, global, religiosa do “mal”, a ser combatida numa guerra - onde as armas eram os textos e as imagens e as instituições judiciais o campo de batalha. Abordarei também, através do estudo de caso do Festival de Santa Rosália em Palermo, a forma como os poderes locais institucionalizaram uma “religião antimáfia”. Neste contexto, discutirei a emergência de uma nova iconografia antimáfia e o uso de um género literário específico: a hagiografia política.

  6. Geneva calling: WHO resolution on mental disorders

    2012-06-01

    Full Text Available Abstract Background A new resolution on mental, neurological and substance use disorders was adopted in January 2012 by the World Health Organization (WHO Executive Board. The resolution urges WHO and Member States to collaborate in the development of a comprehensive mental health action plan, to be submitted for discussion and approval to the WHO World Health Assembly. This commentary aims at rising awareness on the risk that this resolution may not fulfil its potential. Discussion Lack of political awareness and visibility of the resolution is a first major issue. Theoretically, Member States should be aware of the resolution and support its implementation at their respective national level, but in practice political commitment may not be high enough, and technical and financial resources made available may be limited. A second challenge is that the resolution suggests to work with Member States and technical agencies to promote academic exchange through which to contribute to policy-making in mental health. It is not straightforward, however, how such a statement may be effectively translated into action. A third key methodological aspect is how scientific evidence and factors other than scientific evidence will be handled. This seems particularly relevant in the field of mental health, where value-based decisions together with resource and feasibility considerations may be unavoidable. Summary We argue that WHO and Member States should work together to increase the visibility of the resolution, ensuring that Ministries of Health and other relevant components of the health systems are aware of the resolution and its implications. As the resolution urges for academic exchange, WHO should develop a plan for an explicit, inclusive and open call for support and collaboration, so that partners willing to contribute are not kept out from the process. The production of an action plan for mental disorders should be based on scientifically sound

    Full Text Available This contribution presents findings from a qualitative study which focused on young urban professionals in the Philippines who work(ed in international call centers – workplaces usually characterized by job insecurity and other forms of precarity, factory-like working conditions, and disembeddedness. Nevertheless, trade unions in these centers have not come into existence. Why collective action is not chosen by call center agents as an option to tackle the above mentioned problems – this is what the research project this article is based on tried to understand. After outlining some workrelated problems identified by Filipino call center agents, the article will focus on the strategies the agents employ to counter these problems (mainly accommodation and everyday resistance. By highlighting five objective and five subjective reasons (or reasons by circumstances and reasons by framing, we conclude that it is not repressive regulation policies, but rather the formative power and the internalization of discourses of rule within individual life strategies that are preventing the establishment of unions and other collective action structures.

    Full Text Available Conversation between the agent and client are being evaluated manually by a quality assurance officer QA. This job is only one of the responsibilities being done by a QA and particularly eat ups a lot of time for them which lead to late evaluation results that may cause untimely response of the company to concerns raised by their clients. This research developed an application software that automates and evaluates the quality assurance in business process outsourcing companies or customer service management implementing sentence similarity. The developed system includes two modules speaker diarization which includes transcription and question and answer extraction and similarity checker which checks the similarity between the extracted answer and the answer of the call center agent to a question. The system was evaluated for Correctness of the extracted answers and accurateness of the evaluation for a particular call. Audio conversations were tested for the accuracy of the transcription module which has an accuracy of 27.96. The Precision Recall and F-measure of the extracted answer was tested as 78.03 96.26 and 86.19 respectively. The Accuracy of the system in evaluating a call is 70.

    Propose a new degradation call admission control(DCAC)scheme, which can be used in wideband code division multiple access communication system. So-called degradation is that non-real time call has the characteristic of variable bit rate, so decreasing its bit rate can reduce the load of the system, consequently the system can admit new call which should be blocked when the system is close to full load, therefore new call's access probability increases. This paper brings forward design project and does system simulation, simulation proves that DCAC can effectively decrease calls' blocking probability and increase the total number of the on-line users.

    Full Text Available In beach volleyball the setter has the opportunity to give her or his hitter a “call”. The call intends that the setter suggests to her or his partner where to place the attack in the opponent’s court. The effectiveness of a call is still unknown. We investigated the women’s and men’s Swiss National Beach Volleyball Championships in 2011 and analyzed 2185 attacks. We found large differences between female and male players. While men called in only 38.4% of attacks, women used calls in 85.5% of attacks. If the male players followed a given call, 63% of the attacks were successful. The success rate of attacks without any call was 55.8% and 47.6% when the call was ignored. These differences were not significant (χ2(2 = 4.55, p = 0.103. In women’s beach volleyball, the rate of successful attacks was 61.5% when a call was followed, 35% for attacks without a call, and 42.6% when a call was ignored. The differences were highly significant (χ2(2 = 23.42, p < 0.0005. Taking into account the findings of the present study, we suggested that the call was effective in women’s beach volleyball, while its effect in men’s game was unclear. Considering the quality of calls we indicate that there is a significant potential to increase the effectiveness of a call.

  13. Semiconductor-metal transition of Se in Ru-Se Catalyst Nanoparticles

    2009-03-01

    Ru-Se composite nanoparticles are promising catalysts for the oxygen reduction reaction (ORR) in fuel cells. Though the role of Se in enhancing the chemical stability of Ru nanoparticles is well established, the microscopic nature of Ru-Se interaction was not clearly understood. We carried out a combined investigation of ^77Se NMR and XPS on Ru-Se nanoparticles and our results indicate that Se, a semiconductor in elemental form, becomes metallic when interacting with Ru. ^77Se spin-lattice relaxation rates are found to be proportional to T, the well-known Korringa behavior characteristic of metals. The NMR results are supported by the XPS binding energy shifts which suggest that a possible Ru->Se charge transfer could be responsible for the semiconductor->metal transition of Se which also makes Ru less susceptible to oxidation during ORR.

  14. One-step synthesis of PbSe-ZnSe composite thin film

    2011-01-01

    Full Text Available Abstract This study investigates the preparation of PbSe-ZnSe composite thin films by simultaneous hot-wall deposition (HWD from multiple resources. The XRD result reveals that the solubility limit of Pb in ZnSe is quite narrow, less than 1 mol%, with obvious phase-separation in the composite thin films. A nanoscale elemental mapping of the film containing 5 mol% PbSe indicates that isolated PbSe nanocrystals are dispersed in the ZnSe matrix. The optical absorption edge of the composite thin films shifts toward the low-photon-energy region as the PbSe content increases. The use of a phase-separating PbSe-ZnSe system and HWD techniques enables simple production of the composite package.

    2009-03-01

    Full Text Available The title compound, neodymium sesquiselenide, is isotypic with the other known rare-earth metal(III selenides M2Se3 (M = La–Pr and Sm–Lu with the cubic C-type structure. It adopts a cation-defective Th3P4-type arrangement with close to 8/9 of the unique neodymium-cation site occupied, leading to the composition Nd2.667Se4 (Z = 4 or Nd2Se3 (Z = 5.333, respectively. The Nd3+ cations are thus surrounded by eight selenide anions, forming trigonal [NdSe8]13− dodecahedra, whereas the Se2− anions exhibit a sixfold coordination, but due to the under-occupation of neodymium, each one is statistically surrounded by only 5.333 cations. The crystal studied was a merohedral twin with a 0.31 (6:0.69 (6 domain ratio.

  17. Synthesis and characterization of ZnSe:Fe/ZnSe core/shell nanocrystals

    2014-04-15

    High-quality ZnSe:Fe/ZnSe core/shell nanocrystals were prepared via a hydrothermal microemulsion technique. Effective surface passivation of monodisperse ZnSe:Fe nanocrystals is achieved by overcoating them with a ZnSe shell. The samples were characterized by means of XRD, EDX, TEM, PSD, XPS, photoluminescence, and Raman spectrum. The results show that the as-synthesized nanocrystals are cubic zinc blende ZnSe structure with high purity and the average particle size of ZnSe:Fe/ZnSe core/shell nanocrystal is larger than that of ZnSe:Fe core. The growth of ZnSe shell causes a small red shift in PL spectra, and then the PL quantum yield (QY) increases from 16% before shell growth to the maximum of 37% after increasing shell thickness up to 1.2 monolayers (ML). Moreover, both transverse optic (TO) and longitudinal optic (LO) phonon modes of ZnSe are shifted toward lower frequency as compared with the reported ones. -- Highlights: • ZnSe:Fe/ZnSe core/shell QDs were prepared by a hydrothermal microemulsion method. • ZnSe shell efficiently passivates surface defects by serving as a physical barrier. • The particle size and PL properties can be turned with the growth of ZnSe shell. • The luminescence efficiency and stability of QDs could be improved in this manner.

    Kaiser Permanente (KP) has been developing its use of call centers as a way to provide an expansive set of healthcare services to KP members efficiently and cost effectively. Since 1995, when The Permanente Medical Group (TPMG) began to consolidate primary care phone services into three physical call centers, the TPMG Appointments and Advice Call Center (AACC) has become the "front office" for primary care services across approximately 89% of Northern California. The AACC provides primary care phone service for approximately 3 million Kaiser Foundation Health Plan members in Northern California and responds to approximately 1 million calls per month across the three AACC sites. A database records each caller's identity as well as the day, time, and duration of each call; reason for calling; services provided to callers as a result of calls; and clinical outcomes of calls. We here summarize this information for the period 2000 through 2003.

    2014-01-01

    Summary For most frogs, advertisement calls are essential for reproductive success, conveying information on species identity, male quality, sexual state and location. While the evolutionary divergence of call characters has been examined in a number of species, the relative impacts of genetic drift or natural and sexual selection remain unclear. Insights into the evolutionary trajectory of vocal signals can be gained by examining how advertisement calls vary in a phylogenetic context. Evolution by genetic drift would be supported if more closely related species express more similar songs. Conversely, a poor correlation between evolutionary history and song expression would suggest evolution shaped by natural or sexual selection. Here, we measure seven song characters in 20 described and two undescribed species of African clawed frogs (genera Xenopus and Silurana) and four populations of X. laevis. We identify three call types — click, burst and trill — that can be distinguished by click number, call rate and intensity modulation. A fourth type is biphasic, consisting of two of the above. Call types vary in complexity from the simplest, a click, to the most complex, a biphasic call. Maximum parsimony analysis of variation in call type suggests that the ancestral type was of intermediate complexity. Each call type evolved independently more than once and call type is typically not shared by closely related species. These results indicate that call type is homoplasious and has low phylogenetic signal. We conclude that the evolution of call type is not due to genetic drift, but is under selective pressure.

  15. EPR of SeO2- and SeO3- radicals in alkaline borate glasses with 77Se isotope

    International Nuclear Information System (INIS)

    Galimov, D.G.; Tarzimanov, K.D.

    1977-01-01

    Alkaline borate glasses with 77 Se were investigated in order to establish the nature of selenium compounds and radicals in glasses. The relationship between alkali ions and the oxygen radical of selenium was determined by decoding the hyperfine structure of the alkaline borate glass EPR spectra obtained before and after γ-irradiation. The irradiated and non-irradiated glasses were characterized by hyperfine splitting of the EPR lines from the α- and β centres. Moreover, the irradiated samples were noted to have a line doublet (signal phi). With intenser reduction conditions of glass fusion, the intensities of α, β, and phi signals were noted to decline. This confirmes the suggestion that these centres were caused by oxygen compouds. The authors concluded that α and β signals were due to the paramagnetic centres of SeO 2 - and [SeO 2 - ]R + , and phi signal to the SeO 3 - radicals

    2011-01-01

    A 0.01 M CaCl(2) extraction is often used to asses the bioavailability of plant nutrients in soils. However, almost no correlation was found between selenium (Se) in the soil extraction and Se content in grass. The recently developed anion Donnan membrane technique was used to analyze chemical speciation of Se in the 0.01 M CaCl(2) extractions of grassland soils and fractionation of DOC (dissolved organic carbon). The results show that most of Se (67-86%) in the extractions (15 samples) are colloidal-sized Se. Only 13-34% of extractable Se are selenate, selenite and small organic Se (<1 nm). Colloidal Se is, most likely, Se bound to or incorporated in colloidal-sized organic matter. The dominant form of small Se compounds (selenate, selenite/small organic compounds) depends on soil. A total of 47-85% of DOC is colloidal-sized and 15-53% are small organic molecules (<1 nm). In combination with soluble S (sulfur) and/or P (phosphor), concentration of small DOC can explain most of the variability of Se content in grass. The results indicate that mineralization of organic Se is the most important factor that controls Se availability in soils. Competition with sulfate and phosphate needs to be taken into account. Further research is needed to verify if concentration of small DOC is a good indicator of mineralization of soil organic matter.

    Full Text Available Objectives. There are no published studies on the Barbados Emergency Ambulance Service and no assessment of the calls that end in nontransported individuals. We describe reasons for the nontransport of potential clients. Methods. We used the Emergency Medical Dispatch (Medical Priority Dispatch System instrument, augmented with five local call types, to collect information on types of calls. The calls were categorised under 7 headings. Correlations between call types and response time were calculated. Results. Most calls were from the category medical (54%. Nineteen (19% percent of calls were in the non-transported category. Calls from call type Cancelled accounted for most of these and this was related to response time, while Refused service was inversely related (. Conclusions. The Barbados Ambulance Service is mostly used by people with a known illness and for trauma cases. One-fifth of calls fall into a category where the ambulance is not used often due to cancellation which is related to response time. Other factors such as the use of alternative transport are also important. Further study to identify factors that contribute to the non-transported category of calls is necessary if improvements in service quality are to be made.

    Thin films of PbSe of 400-600 nm in thickness, were obtained via chemical deposition from a solution containing lead nitrate, thiourea and selenosufate. SnSe thin films of 90-180 nm in thickness, were also obtained by chemical deposition from a solution containing selenosulfate. Optical and electrical properties of these thin films were significantly altered by heating them in selenium vapor at 300 °C. Thin film PbSe has a bandgap (Eg) of 1.17 eV (direct gap, forbidden transitions), which decreases to 0.77 eV when it has been heated. Its electrical conductivity (σ) is p-type: 0.18 Ω-1 cm-1 (as-prepared), and 6.4 Ω-1 cm-1 when heated. Thin film SnSe is of orthorhombic crystalline structure which remains stable when heated at 300 °C, but its Eg increases from 1.12 eV (indirect) in as-prepared film to 1.5 eV (direct, forbidden transitions) upon heating. Its electrical conductivity is p-type, which increases from 0.3 Ω-1 cm-1 (as-prepared) to 1 Ω-1 cm-1 when heated (without Se-vapor). When SnSe film is heated at 300 °C in the presence of Se-vapor, they transform to SnSe2, with Eg of 1.5 eV (direct, forbidden) with n-type electrical conductivity, 11 Ω-1 cm-1. The Seebeck coefficient for the PbSe films is: +0.55 mV K-1 (as prepared) and +0.275 mV K-1 (heated); for SnSe films it is: +0.3 mV K-1 (as prepared) and +0.20 mV K-1 (heated); and for SnSe2 film, - 0.35 mV K-1. A five-element PbSe-SnSe2-PbSe-SnSe2-PbSe thermoelectric device demonstrated 50 mV for a temperature difference ΔT = 20 °C (2.5 mV K-1). For SnSe-SnSe2-SnSe-SnSe2-SnSe device, the value is 15 mV for ΔT = 20 °C (0.75 mV K-1). Prospect of these thin films in thermoelectric devices of hybrid materials, in which the coatings may be applied on distinct substrate and geometries is attractive.

    Full Text Available O objetivo deste artigo é compreender o contexto do trabalho na chamada sociedade da informação e as diferentes formas de trabalho que nela se desenvolvem, em especial o teletrabalho em call centers. Diante de um novo paradigma tecnológico, característico da era da informação, trata-se de analisar as diferentes configurações do trabalho. O trabalho em call centers parece condensar as ambigüidades de um trabalho informacional com alto controle, o que o colocaria entre as esperanças do pós-taylorismo e os temores do neo-taylorismo. A Teoria Crítica de Axel Honneth permite-nos pensar a experiência do trabalho no seio daquilo que o autor intitula "paradoxos do capitalismo". O significado do trabalho, em sua dimensão social, ganha força ao ser demonstrado que o "novo capitalismo" logra produzir progresso moral, baseado nos legados do Estado Social e do modelo taylorista e fordista de trabalho, e, simultaneamente, produz o seu contrário, ao erodir o alcance emancipador dessas normas e valores. Este estudo analisa o trabalho em call centers em três países de língua portuguesa: Brasil, Portugal e Cabo Verde.

    Adverse effects by night-call duty have become an important occupational health issue. The aim of this study was to investigate whether the heart rate variability (HRV) differed during recovery from day work and night-call duty between distinct physician specialities. We studied the impact of a 16-h night-call duty on autonomic balance, measured by HRV, among two physician groups differing with respect to having to deal with life-threatening conditions while on call. Nineteen anaesthesiologists (ANEST) and 16 paediatricians and ear, nose and throat surgeons (PENT) were monitored by ambulatory digital Holter electrocardiogram (ECG). Heart rate variability was analysed between 21:00 and 22:00 after an ordinary workday, on night call and in the evening post-call. Absolute and normalized high-frequency power (HF, HFnu) were the main outcome variables, expressing parasympathetic influence on the heart. ANEST had lower HF power than PENT while on night call and post-daytime work (p work compared with post-night-call duty (p balance and did not differ between specialities. However, the less dynamic HRV after daytime work and during night-call duty in the ANEST group may indicate a higher physiological stress level. These results may contribute to the improvement of night-call schedules within the health care sector.

    Small amount of Se atoms are used to tune the carrier concentrations (n H ) and electrical transport in Ag 2 Se. Significant enhancements in power factor and thermoelectric figure of merit (zT) are observed in the compositions of Ag 2 Se 1.06 and Ag 2 Se 1.08 . The excessive Se atoms do not change the intrinsically electron-conducting character in Ag 2 Se. The detailed analysis reveals the experiment optimum carrier concentration in Ag 2 Se is around 5 × 10 18  cm −3 . We also investigate the temperature of maximum zT and the thermoelectric transport during the first order phase transitions using the recently developed measurement system

    The (γ, n) cross sections of Se isotopes ( 76 Se, 78 Se) were measured to supply fundamental data for estimating the inverse reaction cross section, i.e., the 79 Se(n, γ) 80 Se cross section. The enriched samples and a reference 197 Au sample were irradiated with laser-Compton scattering (LCS) γ-rays. The excitation function of each (γ, n) cross section was determined for the energy range from each near neutron separation energy to the threshold energy of (γ, 2n) reaction. The energy point corresponding to each cross section was deduced using the accurately determined energy distribution of LCS γ-rays. Systematic (γ, n) cross sections for Se isotopes including 80 Se were compared with those calculated by using a statistical model calculation code TALYS. (author)

    On-call working arrangements are employed in a number of industries to manage unpredictable events, and often involve tasks that are safety- or time-critical. This study investigated the effects of call likelihood during an overnight on-call shift on self-reported pre-bed anxiety, sleep and next-day cognitive performance. A four-night laboratory-based protocol was employed, with an adaptation, a control and two counterbalanced on-call nights. On one on-call night, participants were instructed that they would definitely be called during the night, while on the other on-call night they were told they may be called. The State-Trait Anxiety Inventory form x-1 was used to investigate pre-bed anxiety, and sleep was assessed using polysomnography and power spectral analysis of the sleep electroencephalographic analysis. Cognitive performance was assessed four times daily using a 10-min psychomotor vigilance task. Participants felt more anxious before bed when they were definitely going to be called, compared with the control and maybe conditions. Conversely, participants experienced significantly less non-rapid eye movement and stage two sleep and poorer cognitive performance when told they may be called. Further, participants had significantly more rapid eye movement sleep in the maybe condition, which may be an adaptive response to the stress associated with this on-call condition. It appears that self-reported anxiety may not be linked with sleep outcomes while on-call. However, this research indicates that it is important to take call likelihood into consideration when constructing rosters and risk-management systems for on-call workers.

    Full text : The semiconductive InSe layer compound is characterized by a strong covalent bond inside the layers and a weak Van der Waals bonding between them. It was shown that across the layers of InSe single crystals at low temperatures (T ≤ 200 K) at direct current (dc) hopping conduction through localized states near the Fermi level takes place. The results of dc-conductivity of gamma-irradiated p-InSe and n-InSe : Sn layer single crystals have been presented in this work. ρ-InSe single crystal specimens grown by the Bridgman method were used in the experiments. Plates of the crystals under study were obtained by cleaving along the layers of single crystal ingots. The single-crystal InSe samples for electric measurements had the form of planar capacitors normal to the C axis of the crystals, with silver-paste electrodes. The thickness of the InSe samples was 300 mkm. Co 60 serves as the source of irradiation with energy of gamma-quantum equal to 1.3 MeV. The electric properties of non-irradiated and gamma-irradiated InSe crystals were measured under the same conditions. It is revealed that InSe and InSe : Sn (0.2 and 0.4 mole percent Sn) single crystals exhibit a variable range hopping conduction along a normal to their natural layers at temperatures T≤200 K in a dc electric field. From experimental data the parameters of localized states of p-InSe and n-InSe : Sn were calculated before and after gamma-irradiation. It is revealed that gamma-irradiation of p-InSe and n-InSe : Sn (0.2 and 0.4 mole percent Sn) single crystals leads to significant change of localized states parameters. After gamma-irradiation the density of states near the Fermi level increased, but their energy spread and the average jump distance decreased. The concentrations of radiated defects were estimated in p-InSe (5.18*10 1 7 sm - 3) and n-InSe : Sn (2.5*10 1 7 - 2.7*10 1 8 sm - 3) single crystals. The present results demonstrate that gamma-irradiation offers the possibility of tuning

    Using a sample of 70 juvenile probationers (39 treatment and 31 controls), we evaluated the effectiveness of a rehabilitation program that combined cognitive-behavioral training and automated phone calls. The cognitive-behavioral training contained six 90-min sessions, one per week, and the phone calls occurred twice per day for the year following treatment. Recidivism was measured by whether they were rearrested and the total number of rearrests during the 1st year. To test the impact of the phone calls, those who received phone calls were divided into high and low groups depending on whether they answered more or less than half of their phone calls. Those who completed the class and answered at least half of their phone calls were less likely to have been arrested and had fewer total arrests.

    An economic study of the the behaviour of financial managers of utility companies was presented. The study examined whether or not an option pricing based model of the call decision does a better job of explaining callable preferred share prices and call decisions compared to other models. In this study, the Rust (1987) empirical technique was extended to include the use of information from preferred share prices in addition to the call decisions. Reasonable estimates were obtained from data of shares of the Pacific Gas and Electric Company (PGE) for the transaction costs associated with a call. It was concluded that the managers of the PGE clearly take into account the value of the option to delay the call when making their call decisions

    The objective of this study was to compare admission rates and medical interventions among children whose caregivers called their child's primary care provider (PCP) before taking an ambulance to the pediatric emergency department (PED) versus those who did not. This was a prospective cohort study of patients brought to an urban, public hospital PED via emergency medical system (EMS). Children were included if the caregiver called 911 to have them transported via EMS and was present in the PED. The main variable was whether the child's PCP was called before EMS utilization. Study outcomes were medical interventions, such as intravenous line insertion or laboratory tests, and hospital admission. χ Test and logistic regression were used to evaluate the relationship of the main variable to the study outcomes. Six hundred fourteen patients met inclusion criteria and were enrolled. Five hundred eighty-five patients (95.3%) were reported to have a PCP. Seventy-four caregivers (12.1%) called their child's PCP before calling EMS. Two hundred seventy-seven patients (45.1%) had medical interventions performed; of these, 42 (15.2%) called their PCP (P = 0.03). Forty-two patients (6.8%) were admitted; among these, 14 (33.3%) called their PCP (P < 0.01). Adjusting for triage level, patients whose caregiver called the PCP before calling EMS were 3.2 times (95% confidence interval, 1.9-5.2 times) more likely to be admitted and 1.7 times (95% confidence interval, 1.1-2.9 times) more likely to have a medical intervention compared with patients whose caregivers did not call their child's PCP. Children were more likely to be admitted or require a medical intervention if their caregiver called their PCP before calling EMS. The availability of a PCP for telephone triage may help to optimize EMS utilization.

    We report the design, fabrication, and characterization of colloidal PbSe nanocrystal (NC)-based photovoltaic test structures that exhibit an excitonic solar cell mechanism. Charge extraction from the NC active layer is driven by a photoinduced chemical potential energy gradient at the nanostructured heterojunction. By minimizing perturbation to PbSe NC energy levels and thereby gaining insight into the "intrinsic" photovoltaic properties and charge transfer mechanism of PbSe NC, we show a direct correlation between interfacial energy level offsets and photovoltaic device performance. Size dependent PbSe NC energy levels were determined by cyclic voltammetry and optical spectroscopy and correlated to photovoltaic measurements. Photovoltaic test structures were fabricated from PbSe NC films sandwiched between layers of ZnO nanoparticles and PEDOT:PSS as electron and hole transporting elements, respectively. The device current-voltage characteristics suggest a charge separation mechanism that Is distinct from previously reported Schottky devices and consistent with signatures of excitonic solar cells. Remarkably, despite the limitation of planar junction structure, and without film thickness optimization, the best performing device shows a 1-sun power conversion efficiency of 3.4%, ranking among the highest performing NC-based solar cells reported to date. © 2009 American Chemical Society.

    A transferable force field for the PbSe-CdSe solid system using the partially charged rigid ion model has been successfully developed and was used to study the cation exchange in PbSe-CdSe heteronanocrystals [A. O. Yalcin et al., "Atomic resolution monitoring of cation exchange in CdSe-PbSe heteronanocrystals during epitaxial solid-solid-vapor growth," Nano Lett. 14, 3661-3667 (2014)]. In this work, we extend this force field by including another two important binary semiconductors, PbS and CdS, and provide detailed information on the validation of this force field. The parameterization combines Bader charge analysis, empirical fitting, and ab initio energy surface fitting. When compared with experimental data and density functional theory calculations, it is shown that a wide range of physical properties of bulk PbS, PbSe, CdS, CdSe, and their mixed phases can be accurately reproduced using this force field. The choice of functional forms and parameterization strategy is demonstrated to be rational and effective. This transferable force field can be used in various studies on II-VI and IV-VI semiconductor materials consisting of CdS, CdSe, PbS, and PbSe. Here, we demonstrate the applicability of the force field model by molecular dynamics simulations whereby transformations are initiated by cation exchange.

    Objectives: This research explored the use of management information and its impact on two fundamental functions namely, improving productivity without compromising the quality of service, in the call centre of a well-known South African fashion retailer, Edcon. Following the implementation of the call centre technology project the research set out to determine how Edcon can transform their call centre to improve productivity and customer service through effective utilisation of their management information. Method: Internal documents and reports were analysed to provide the basis of evaluation between the measures of productivity prior to and post the implementation of a technology project at Edcon’s call centre. Semi-structured in-depth and group interviews were conducted to establish the importance and use of management information in improving productivity and customer service. Results: The results indicated that the availability of management information has indeed contributed to improved efficiency at the Edcon call centre. Although literature claims that there is a correlation between a call centre technology upgrade and improvement in performance, evident in the return on investment being realised within a year or two of implementation, it fell beyond the scope of this study to investigate the return on investment for Edcon’s call centre. Conclusion: Although Edcon has begun realising benefits in improved productivity in their call centre from their available management information, information will continue to play a crucial role in supporting management with informed decisions that will improve the call centre operations.

    Full Text Available Abstract Many professions in the fields of engineering, aviation and medicine employ this form of scheduling. However, on-call work has received significantly less research attention than other work patterns such as shift work and overtime hours. This paper reviews the current body of peer-reviewed, published research conducted on the health effects of on-call work The health effects studies done in the area of on-call work are limited to mental health, job stress, sleep disturbances and personal safety. The reviewed research suggests that on-call work scheduling can pose a risk to health, although there are critical gaps in the literature.

  6. The Influence of Judgment Calls on Meta-Analytic Findings.

    2016-01-01

    Previous research has suggested that judgment calls (i.e., methodological choices made in the process of conducting a meta-analysis) have a strong influence on meta-analytic findings and question their robustness. However, prior research applies case study comparison or reanalysis of a few meta-analyses with a focus on a few selected judgment calls. These studies neglect the fact that different judgment calls are related to each other and simultaneously influence the outcomes of a meta-analysis, and that meta-analytic findings can vary due to non-judgment call differences between meta-analyses (e.g., variations of effects over time). The current study analyzes the influence of 13 judgment calls in 176 meta-analyses in marketing research by applying a multivariate, multilevel meta-meta-analysis. The analysis considers simultaneous influences from different judgment calls on meta-analytic effect sizes and controls for alternative explanations based on non-judgment call differences between meta-analyses. The findings suggest that judgment calls have only a minor influence on meta-analytic findings, whereas non-judgment call differences between meta-analyses are more likely to explain differences in meta-analytic findings. The findings support the robustness of meta-analytic results and conclusions.

    Full Text Available O objetivo deste artigo é introduzir elementos da reprodução econômica da sociedade capitalista na avaliação da dinâmica contemporânea da acumulação da saúde. São identificadas a direção e o sentido da acumulação de capital e o ambiente onde se desenvolvem os atuais processos de competição.O trabalho considerou a hipótese da hipertrofia da órbita financeira como um modo de estruturação da economia capitalista desde o último quartel do século XX, onde ficam embaçadas e corroídas antigas delimitações entre produção de bens e prestação de serviços. Mudam os padrões de competição entre as empresas, bem como as contradições internas e externas ao setor saúde. A abordagem é teórico-histórico-conceitual, visando aportar elementos para uma abordagem contemporânea do tema "complexo médico-industrial". São identificadas transformações internacionais e nacionais referentes à dinâmica do capital no complexo, com destaque para o crescente papel dos serviços. A nova abordagem é elaborada a partir do pensamento econômico de Marx, acrescido da discussão contemporânea sobre financeirização e novas configurações produtivas da grande empresa. Ao final, o caráter das contradições existentes no interior do complexo produtivo da saúde é problematizado.The purpose of this article is to introduce elements of the capitalist society economic reproduction to the discussion around the current dynamics of health accumulation. It identifies the direction and significance of capital accumulation in the health area as well as the characteristics of the economic environment where the competition currently takes place. The hypothetic hypertrophy of the financial sphere is seen as a means for structuring the capitalist economy since the late twentieth century. The former delimitations between industrial production and service delivery are blurred and weakened; the competition process shows new features and the

    Full Text Available O objetivo deste trabalho foi avaliar as transformações do N no solo após a aplicação de dejeto líquido (DLS e cama sobreposta (CSS de suínos, com e sem palha de aveia, e com e sem incorporação ao solo. Os tratamentos avaliados foram: solo (S, S + palha incorporada (S + Pi, S + palha em superfície (S + Ps, S + CSS incorporada (S + CSSi, S + CSS em superfície (S + CSSs, S + DLS incorporado (S + DLSi, S + DLS em superfície (S + DLSs, S + Pi + DLSi e S + Ps + DLSs. Avaliaram-se a volatilização de amônia, a nitrificação e a mineralização do N do DLS e da CSS. A incorporação do DLS reduziu a volatilização de amônia em 93%, em comparação à aplicação na superfície do solo. O N amoniacal da CSS foi nitrificado nos cinco primeiros dias. A taxa de nitrificação líquida foi duas vezes maior com a incorporação do DLS ao solo do que na superfície. A mineralização do N orgânico não diferiu com o modo de aplicação do DLS e da CSS no solo. Na CSS, 14,6% do N foi mineralizado, contra 34,9% no DLS. A aplicação do DLS com a palha de aveia na superfície do solo favorece a imobilização microbiana de N, mas não reduz as perdas de N por volatilização de amônia.The objective of this work was to evaluate soil N transformations after the application of pig slurry (PS and pig deep‑litter (PDL, with and without oat straw, and with and without incorporation into the soil.

    Full Text Available The conversion of p-coumaric acid, ferulic acid, and caffeic acid into 4-ethylphenol, 4-ethylguaiacol and 4-ethylcatechol was studied in Dekkera bruxellensis ISA 1791 under defined conditions in a synthetic medium and in a red wine. Liquid chromatography (HPLC-DAD was used to quantify the phenolic acids, and gas chromatography (GC coupled to a FID detector was used to quantify volatile phenols using a novel analytical methodology that does not require sample derivatization. Identification was achieved by gas chromatography-mass detection (GC-MS. The results show that phenolic acids concentration decreases while volatile phenols concentration increases. The proportion of caffeic acid taken up by Dekkera bruxellensis is lower than that for p-coumaric or ferulic acid; therefore less 4-ethylcatechol is formed. More important, 4-ethylcathecol synthesis by Dekkera bruxellensis in wine has never been demonstrated so far. These results contribute decisively to a better understanding of the origin of the volatile phenols in wines. The accumulation of these compounds in wine is nowadays regarded as one of the key factors of quality control.A transformação do ácido p-cumárico, ácido ferúlico e ácido cafeico em 4-etilfenol, 4-etilguaiacol e 4-etilcatecol foi estudada na presença de Dekkera bruxelensis ISA 1791, sob condições controladas, em meio sintético e em vinho tinto. Os compostos fenólicos foram doseados por cromatografia em fase líquida (HPLC-DAD e os fenóis voláteis foram doseados por cromatografia em fase gasosa (GC com detector de ionização de chama (FID, recorrendo a uma metodologia que não requer prévia derivatização da amostra. A identificação dos compostos foi comprovada por espectrometria de massa (GC-MS.

    The phonon dispersions and phonon density of states of LaSe are obtained, based on density functional perturbation theory and the norm-conserving pseudo-potential method. An anomaly in calculated phonon dispersion curves is presented and interpreted as a Kohn anomaly. The heat capacity of LaSe is calculated then. For the three-phonon process scattering, the lowest non-harmonic cubic terms of the interatomic potential are considered to obtain single-phonon relaxation rate by applying the Fermi's golden rule. For the boundary scattering, the average phonon relaxation time was obtained. Considering two kinds of phonon scattering mechanisms, we obtain the lattice thermal conductivity of LaSe.

    Size-controllable monodisperse CdSe nanocrystals with different organic capping were prepared based on the hot-injection method. The effective separation of nucleation and growth was achieved by rapidly mixing two highly reactive precursors. As a contrast, we prepared CdSe/CdS nanocrystals (NCs) successfully based on the selective ion layer adsorption and reaction (SILAR) technique. This inorganic capping obtained higher photoluminescence quantum yield (PLQY) of 59.3% compared with organic capping of 40.8%. Furthermore, the CdSe-epoxy resin (EP) composites were prepared by adopting a flexible ex situ method, and showed excellent stability in the ambient environment for one year. So the composites with both high PLQY of nanocrystals and excellent stability are very promising to device application.

    Density estimates accounting for differential animal detectability are difficult to acquire for wide-ranging and elusive species such as mammalian carnivores. Pairing distance sampling with call-response surveys may provide an efficient means of tracking changes in populations of coyotes (Canis latrans), a species of particular interest in the eastern United States. Blind field trials in rural New York State indicated 119-m linear error for triangulated coyote calls, and a 1.8-km distance threshold for call detectability, which was sufficient to estimate a detection function with precision using distance sampling. We conducted statewide road-based surveys with sampling locations spaced ≥6 km apart from June to August 2010. Each detected call (be it a single or group) counted as a single object, representing 1 territorial pair, because of uncertainty in the number of vocalizing animals. From 524 survey points and 75 detections, we estimated the probability of detecting a calling coyote to be 0.17 ± 0.02 SE, yielding a detection-corrected index of 0.75 pairs/10 km2 (95% CI: 0.52–1.1, 18.5% CV) for a minimum of 8,133 pairs across rural New York State. Importantly, we consider this an index rather than true estimate of abundance given the unknown probability of coyote availability for detection during our surveys. Even so, pairing distance sampling with call-response surveys provided a novel, efficient, and noninvasive means of monitoring populations of wide-ranging and elusive, albeit reliably vocal, mammalian carnivores. Our approach offers an effective new means of tracking species like coyotes, one that is readily extendable to other species and geographic extents, provided key assumptions of distance sampling are met.

    2014-01-01

    Highlights: • Nucleation behavior of As 2 Se 3 glass was studied by DSC in dependence on particle size. • Correlation between the enthalpies of fusion and crystallization were confirmed. • Apart from classical heterogeneous nucleation a second nucleation mechanism was found. • Rapid formation of crystallization centers from a damaged glassy structure occurs. • Mechanical defects seem to partially suppress the CNT nucleation process. - Abstract: Differential scanning calorimetry was used to study nucleation behavior in As 2 Se 3 glass, dependent on particle size. The nucleation process was examined for a series of different coarse powders; the nucleation rate was estimated from the proportion of the crystalline material fraction. The enthalpy of fusion was utilized in this respect, and a correlation between ΔH m and ΔH c was confirmed. Two mechanisms of nucleus formation were found: classical heterogeneous nucleation (following CNT) and so-called “activation” of mechanically-induced defects. The latter appears to represent rapid formation of crystallization centers from a damaged glassy structure, where complete saturation occurs for fine powders in the range of 195–235 °C. A high amount of mechanical defects, on the other hand, was found to partially suppress the CNT nucleation process

    We have studied the emission spectra and structural properties of double CdSe/ZnSe quantum dot (QD) sheet structures grown by molecular beam epitaxy in order to elucidate the mechanisms of the electronic and strain field interaction between the QD planes. The thickness of the ZnSe barrier separating the CdSe sheets was in the range of 10-60 monolayers (ML) in the set of samples studied. We have found that coupling between dots in adjacent layers becomes relatively strong in CdSe/ZnSe double layers structures with 25-27 ML barrier, while it is rather weak when the barrier thickness exceeds 30 ML.

    Hollow NiSe-CoSe samples have been synthesized for the first time via a one-pot solvothermal approach. The strategy is robust enough to synthesize NiSe-CoSe nanoparticles with different NiSe to CoSe ratios but with a similar hollow structure. Co ions in the NiSe-CoSe nanoparticles play decisive role for formation of the hollow structure; otherwise, the nanoparticles become solid for the NiSe sample. When used as the positive electroactive materials for energy storage, the NiSe-CoSe samples show excellent electrochemical activity in alkaline electrolyte. Using the synergistic effect between NiSe and CoSe, the electrochemical performance of NiSe-CoSe can be tuned by varying the NiSe to CoSe ratios. The NiSe-CoSe sample with a NiSe to CoSe ratio of 4:2 shows the best electrochemical performance in terms of superior specific capacity, improved rate capability and excellent cycling stability. In addition, the electrochemical performance of NiSe-CoSe sample with a NiSe to CoSe ratio of 4:2 is also evaluated via assembling hybrid supercapacitors with RGO, and the hybrid supercapacitor delivers both high power and energy densities (41.8 Wh kg-1 at 750 W kg-1 and 20.3 Wh kg-1 at 30 kW kg-1).

    Research highlights: → Determination of the glass-forming region in the pseudo-ternary CdSe-AgI-As 2 Se 3 system. → Characterization of macroscopic properties of the new CdSe-AgI-As 2 Se 3 glasses. → Far infrared transmission of chalcogenide glasses. → Characterization of the total conductivity of CdSe-AgI-As 2 Se 3 glasses. -- Abstract: The glass-forming region in the pseudo-ternary CdSe-AgI-As 2 Se 3 system was determined. Measurements including differential scanning calorimetry (DSC), density, and X-ray diffraction were performed. The effect resulting from the addition of CdSe or AgI has been highlighted by examining three series of different base glasses. The characteristic temperatures of the glass samples, including glass transition (T g ), crystallisation (T x ), and melting (T m ) temperatures are reported and used to calculate their ΔT = T x - T g and their Hruby, H r = (T x - T g )/(T m - T x ), criteria. Evolution of the total electrical conductivity σ and the room temperature conductivity σ 298 was also studied. The terahertz transparency domain in the 50-600 cm -1 region was pointed for different chalcogenide glasses (ChGs) and the potential of the THz spectroscopy was suggested to obtain structural information on ChGs.

    Full Text Available Con el presente artículo pretendemos mostrar una aproximación al complejo universo de las lógicas que dirigen la colonización del espacio público urbano a través de las prácticas físico-deportivas que, en menor o mayor medida, hacen uso y se apropian de las calles y plazas de la ciudad de Barcelona. En las reflexiones que siguen, se observa la heterogeneidad del fenómeno que, lejos de representar en exclusiva la superación y el rebasamiento del sistema deportivo moderno –así como de las características que lo sustentaban– para ubicarse en un universo postmoderno, se presenta como un hecho social total. Un deporte “urbano” que es moderno y postmoderno a la vez, informal y formal, lúdico y competitivo, libre y dirigido, abierto y cerrado, contradictorio y complejo siempre. Este estudio nos permite dibujar las características de algunos itinerarios deportivos urbanos, señalar diferentes perfiles de practicantes y nos acerca a las redes de socialidad que se establecen en este contexto. Las investigaciones empíricas que apoyan la parte de revisión teórica de este estudio, se basan en una serie de trabajos realizados desde el “Grup de Recerca i Innovació en Esport i Societat” (GRIES de la Universitat Ramon Llull, que incorporan un trabajo de campo realizado en diferentes fases durante el periodo 2002-2006.

    Although acoustic signals are important for communication in many taxa, signal propagation is affected by environmental properties. Strong environmental constraints should drive call evolution, favoring signals with greater transmission distance and content integrity in a given calling habitat. Yet, few empirical studies have verified this prediction, possibly due to a shortcoming in habitat characterization, which is often too broad. Here we assess the potential impact of environmental constraints on the evolution of advertisement call in four groups of torrent-dwelling frogs in the family Ranidae. We reconstruct the evolution of calling site preferences, both broadly categorized and at a finer scale, onto a phylogenetic tree for 148 species with five markers (∼3600 bp). We test models of evolution for six call traits for 79 species with regard to the reconstructed history of calling site preferences and estimate their ancestral states. We find that in spite of existing morphological constraints, vocalizations of torrent-dwelling species are most probably constrained by the acoustic specificities of torrent habitats and particularly their high level of ambient noise. We also show that a fine-scale characterization of calling sites allows a better perception of the impact of environmental constraints on call evolution. © 2016 The Author(s).

    Based on the current tools, de novo secretome (full set of proteins secreted by an organism) prediction is a time consuming bioinformatic task that requires a multifactorial analysis in order to obtain reliable in silico predictions. Hence, to accelerate this process and offer researchers a reliable repository where secretome information can be obtained for vertebrates and model organisms, we have developed VerSeDa (Vertebrate Secretome Database). This freely available database stores information about proteins that are predicted to be secreted through the classical and non-classical mechanisms, for the wide range of vertebrate species deposited at the NCBI, UCSC and ENSEMBL sites. To our knowledge, VerSeDa is the only state-of-the-art database designed to store secretome data from multiple vertebrate genomes, thus, saving an important amount of time spent in the prediction of protein features that can be retrieved from this repository directly. VerSeDa is freely available at http://genomics.cicbiogune.es/VerSeDa/index.php. © The Author(s) 2017. Published by Oxford University Press.

    Full Text Available A new paradigm in second language pedagogy has Computer Assisted Language Learning (CALL playing a significant role. Much of the literature to-date claims that CALL can have a positive impact on students’ second language acquisition (SLA. Mixed method of research produces data to investigate if CALL positively affects student language proficiency, motivation and autonomy. Classroom observation of participants in their natural environment is a qualitative technique used but has situational variables that could skew results if not structured. A questionnaire is a quantitative tool that can offer insight regarding participants’ perception of performance but can contradict what the researcher has observed. This paper will take an in-depth look at variables such as: instructor’s pedagogical application; blending CALL into the curriculum; types of CALL implemented; feedback received and their implications for design of the data collection tools

  10. Call Admission Scheme for Multidimensional Traffic Assuming Finite Handoff User

    Full Text Available Usually, the number of users within a cell in a mobile cellular network is considered infinite; hence, M/M/n/k model is appropriate for new originated traffic, but the number of ongoing calls around a cell is always finite. Hence, the traffic model of handoff call will be M/M/n/k/N. In this paper, a K-dimensional traffic model of a mobile cellular network is proposed using the combination of limited and unlimited users case. A new call admission scheme (CAS is proposed based on both thinning scheme and fading condition. The fading condition of the wireless channel access to a handoff call is prioritized compared to newly originated calls.

    1983-01-01

    Communication errors involving aircraft call signs were portrayed in reports of 462 hazardous incidents voluntarily submitted to the ASRS during an approximate four-year period. These errors resulted in confusion, disorder, and uncoordinated traffic conditions and produced the following types of operational anomalies: altitude deviations, wrong-way headings, aborted takeoffs, go arounds, runway incursions, missed crossing altitude restrictions, descents toward high terrain, and traffic conflicts in flight and on the ground. Analysis of the report set resulted in identification of five categories of errors involving call signs: (1) faulty radio usage techniques, (2) call sign loss or smearing due to frequency congestion, (3) confusion resulting from similar sounding call signs, (4) airmen misses of call signs leading to failures to acknowledge or readback, and (5) controller failures regarding confirmation of acknowledgements or readbacks. These error categories are described in detail and several associated hazard mitigating measures that might be aken are considered.

    This document discusses various issues associated with the planned competitive call on the French hydraulic power plants. The principles of this competitive call for hydroelectric concessions are first addressed: administrative regime of concessions, competitive call process, criteria of selection of the concession holder, case of 'concession of valleys', potential competitors. It outlines and discusses the difficulties of this competitive call: France is the single country to implement this procedure; it concerns a national asset; it questions the guarantee of a future use of equipment at best for the energy benefits of French consumers; the competitive call is a nice idea indeed but extremely complex. A note discusses the profitability aspects of Plants for Transfer of Energy by Pumping

  13. Evidence That Calls-Based and Mobility Networks Are Isomorphic.

    Directory of Open Access Journals (Sweden)

    Michele Coscia

    Full Text Available Social relations involve both face-to-face interaction as well as telecommunications. We can observe the geography of phone calls and of the mobility of cell phones in space. These two phenomena can be described as networks of connections between different points in space. We use a dataset that includes billions of phone calls made in Colombia during a six-month period. We draw the two networks and find that the call-based network resembles a higher order aggregation of the mobility network and that both are isomorphic except for a higher spatial decay coefficient of the mobility network relative to the call-based network: when we discount distance effects on the call connections with the same decay observed for mobility connections, the two networks are virtually indistinguishable.

    The advertisement call plays an important role in the life history of anuran amphibians, mainly during the breeding season. Call features represent an important character to discriminate species, and sound emissions are very effective to assure or reinforce genetic incompatibility, especially in the case of sibling species. Since frogs are ectotherms, acoustic properties of their calls will vary with temperature. In this study, we described the advertisement call of C. cranwelli, quantifying the temperature effect on its components. The acoustic emissions were recorded during 2007 using a DAT record Sony TCD-100 with stereo microphone ECM-MS907 Sony and tape TDK DAT-RGX 60. As males emit their calls floating in temporary ponds, water temperatures were registered after recording the advertisement calls with a digital thermometer TES 1300+/-0.1 degreeC. Altogether, 54 calls from 18 males were analyzed. The temporal variables of each advertisement call were measured using oscillograms and sonograms and the analyses of dominant frequency were performed using a spectrogram. Multiple correlation analysis was used to identify the temperature-dependent acoustic variables and the temperature effect on these variables was quantified using linear regression models. The advertisement call of C. cranwelli consists of a single pulse group. Call duration, Pulse duration and Pulse interval decreased with the temperature, whereas the Pulse rate increased with temperature. The temperature-dependent variables were standardized at 25 degreeC according to the linear regression model obtained. The acoustic variables that were correlated with the temperature are the variables which emissions depend on laryngeal muscles and the temperature constraints the contractile properties of muscles. Our results indicated that temperature explains an important fraction of the variability in some acoustic variables (79% in the Pulse rate), and demonstrated the importance of considering the effect of

    We report first-principles band structure calculations that show that ZnSe/CuInSe 2 has a significant valence band offset (VBO, ΔE v ): 0.70±0.05 eV for the relaxed interface and 0.60±0.05 eV for the coherent interface. These large values demonstrate the failure of the common anion rule. This is traced to a stronger Cu,d-Se,p level repulsion in CuInSe 2 than the Zn,d-Se,p repulsion in ZnSe. The VBO was then studied by synchrotron radiation soft x-ray photoemission spectroscopy. ZnSe overlayers were sequentially grown in steps on n-type CuInSe 2 (112) single crystals at 200 degree C. In situ photoemission measurements were acquired after each growth in order to observe changes in the valence band electronic structure as well as changes in the In 4d and Zn 3d core lines. Results of these measurements reveal that the VBO is ΔE v =0.70±0.15 eV, in good agreement with the first-principles prediction

  1. Anisotropy in CdSe quantum rods

    Energy Technology Data Exchange (ETDEWEB)

    2003-01-01

    The size-dependent optical and electronic properties of semiconductor nanocrystals have drawn much attention in the past decade, and have been very well understood for spherical ones. The advent of the synthetic methods to make rod-like CdSe nanocrystals with wurtzite structure has offered us a new opportunity to study their properties as functions of their shape. This dissertation includes three main parts: synthesis of CdSe nanorods with tightly controlled widths and lengths, their optical and dielectric properties, and their large-scale assembly, all of which are either directly or indirectly caused by the uniaxial crystallographic structure of wurtzite CdSe. The hexagonal wurtzite structure is believed to be the primary reason for the growth of CdSe nanorods. It represents itself in the kinetic stabilization of the rod-like particles over the spherical ones in the presence of phosphonic acids. By varying the composition of the surfactant mixture used for synthesis we have achieved tight control of the widths and lengths of the nanorods. The synthesis of monodisperse CdSe nanorods enables us to systematically study their size-dependent properties. For example, room temperature single particle fluorescence spectroscopy has shown that nanorods emit linearly polarized photoluminescence. Theoretical calculations have shown that it is due to the crossing between the two highest occupied electronic levels with increasing aspect ratio. We also measured the permanent electric dipole moment of the nanorods with transient electric birefringence technique. Experimental results on nanorods with different sizes show that the dipole moment is linear to the particle volume, indicating that it originates from the non-centrosymmetric hexagonal lattice. The elongation of the nanocrystals also results in the anisotropic inter-particle interaction. One of the consequences is the formation of liquid crystalline phases when the nanorods are dispersed in solvent to a high enough

    Background Call light systems remain the primary means of hospitalized patients to initiate communication with their health care providers. Although there is vast amounts of literature discussing patient communication with their health care providers, few studies have explored patients’ perceptions concerning call light use and communication. The specific aim of this study was to solicit patients’ perceptions regarding their call light use and communication with nursing staff. Methods Patients invited to this study met the following inclusion criteria: proficient in English, been hospitalized for at least 24 hours, aged ≥21 years, and able to communicate verbally (eg, not intubated). Thirty participants provided written informed consent, were enrolled in the study, and completed interviews. Results Using qualitative descriptive methods, five major themes emerged from patients’ perceptions (namely; establishing connectivity, participant safety concerns, no separation: health care and the call light device, issues with the current call light, and participants’ perceptions of “nurse work”). Multiple minor themes supported these major themes. Data analysis utilized the constant comparative methods of Glaser and Strauss. Discussion Findings from this study extend the knowledge of patients’ understanding of not only why inconsistencies occur between the call light and their nurses, but also why the call light is more than merely a device to initiate communication; rather, it is a direct conduit to their health care and its delivery.

    One hundred and thirty-eight echolocation calls of 63 free-flying individuals of five bat species (Rhinolophus ferrumequinum,Myotis formosus,Myotis ikonnikovi,Myotis daubentoni and Murina leucogaster)were recorded (by ultrasonic bat detector (D980)) in Zhi'an village of Jilin Province,China.According to the frequency-time spectra,these calls were categorized into two types:FM/CF (constant frequency) / FM (R.ferrumequinum) and FM (frequency modulated)(M.formosus,M.ikonnikovi,M.daubentoni and M.leucogaster).Sonograms of the calls of R.ferrumequinum could easily be distinguished from those of the other four species.For the calls of the remaining four species,six echolocation call parameters,including starting frequency,ending frequency,peak frequency duration,longest inter-pulse interval and shortest inter-pulse interval,were examined by stepwise discriminant analysis.The results show that 84.1% of calls were correctly classified,which indicates that these parameters of echolocation calls play an important role in identifying bat species.These parameters can be used to test the accuracy of general predictions based on bats' morphology in the same forest and can provide essential information for assessing patterns of bat habitat use.

    Objective This study assessed the cost effectiveness of different types of television and radio advertisements and the time of day in which advertisements were placed in generating calls to the Oregon tobacco quitline. Design Cost effectiveness was measured by cost per call, calculated as the cost of advertising divided by the number of quitline calls generated by that advertising. Advertising was bought in one‐week or two‐week blocks and included 27 daytime television buys, 22 evening television buys and 31 radio buys. Results Cost effectiveness varied widely by medium, time of day and advertisement used. Daytime television was seven times more cost effective than evening television and also more cost effective than radio. The most effective advertisements at generating quitline calls were real life testimonials by people who lost family members to tobacco and advertisements that deal practically with how to quit. Conclusions Placement of television advertisements during the day versus the evening can increase an advertisement's effectiveness in generating calls to a quitline. Some advertising messages were more effective than others in generating calls to a quitline. Quitline providers can apply findings from previous research when planning media campaigns. In addition, call volume should be monitored in order to assess the cost effectiveness of different strategies to promote use of the quitline. PMID:18048626

  6. Frogs Call at a Higher Pitch in Traffic Noise

    Directory of Open Access Journals (Sweden)

    Kirsten M. Parris

    2009-06-01

    Full Text Available Male frogs call to attract females for mating and to defend territories from rival males. Female frogs of some species prefer lower-pitched calls, which indicate larger, more experienced males. Acoustic interference occurs when background noise reduces the active distance or the distance over which an acoustic signal can be detected. Birds are known to call at a higher pitch or frequency in urban noise, decreasing acoustic interference from low-frequency noise. Using Bayesian linear regression, we investigated the effect of traffic noise on the pitch of advertisement calls in two species of frogs, the southern brown tree frog (Litoria ewingii and the common eastern froglet (Crinia signifera. We found evidence that L. ewingii calls at a higher pitch in traffic noise, with an average increase in dominant frequency of 4.1 Hz/dB of traffic noise, and a total effect size of 123 Hz. This frequency shift is smaller than that observed in birds, but is still large enough to be detected by conspecific frogs and confer a significant benefit to the caller. Mathematical modelling predicted a 24% increase in the active distance of a L. ewingii call in traffic noise with a frequency shift of this size. Crinia signifera may also call at a higher pitch in traffic noise, but more data are required to be confident of this effect. Because frog calls are innate rather than learned, the frequency shift demonstrated by L. ewingii may represent an evolutionary adaptation to noisy conditions. The phenomenon of frogs calling at a higher pitch in traffic noise could therefore constitute an intriguing trade-off between audibility and attractiveness to potential mates.

    We present a study of entropy transport in Bi2Se3 at low temperatures and high magnetic fields. In the zero-temperature limit, the magnitude of the Seebeck coefficient quantitatively tracks the Fermi temperature of the three-dimensional Fermi surface at the Γ point as the carrier concentration changes by two orders of magnitude (1017 to 1019 cm-3). In high magnetic fields, the Nernst response displays giant quantum oscillations indicating that this feature is not exclusive to compensated semimetals. A comprehensive analysis of the Landau level spectrum firmly establishes a large g factor in this material and a substantial decrease of the Fermi energy with increasing magnetic field across the quantum limit. Thus, the presence of bulk carriers significantly affects the spectrum of the intensively debated surface states in Bi2Se3 and related materials.

  12. Properties of the CuGaSe2 and CuInSe2 (001) surface

    Deniozou, T.

    2005-01-01

    The main task of this work was to investigate the (001) CuGaSe 2 and CuInSe 2 surface in dependence of preparation and stoichiometry. The knowledge of the atomic structure as well as other surface properties is important in respect to optimization of novel thin film solar cells. For the characterization of the layers mainly Auger electron Spectroscopy, low-energy electron diffraction and photoelectron spectroscopy were implemented. The development of an appropriate procedure with Ar + sputtering and annealing combined with decapping enabled the preparation of clean and well-ordered surfaces. Different surface structures were observed in dependence of the layer preparation and composition. A (4 x 1) reconstruction was observed for the first time on CuGaSe 2 layers grown with a moderate Cu-excess after preparation by sputtering and annealing. Similarly a (4 x 2) reconstruction was detected on CuInSe2 surfaces of Cu-poor layers. A reconstruction could be also observed on Cu-poorer layers, however the facets/steps could not be completely removed. Cu-richer layers were facet-free, however the observed reconstruction was also weaker. Thus it was shown that in contrary to recent expectations, according to which only the (112) surface is stable, also the (001) can be stable under particular conditions. The appearance of facets or steps is correlated with the presence of CuIn 3 Se 5 or CuGa 3 Se 5 phases. This information is furthermore important for the understanding of grain boundaries in polycrystalline CuGaSe 2 and CuInSe 2 . Binding energy shifts were observed for the first time on all Se3d, In4d, Ga3d, Cu3d core levels of the reconstructed surfaces. By comparison with results from the literature from the similar ZnSe (100) surface a modell for the (4 x 2) reconstruction was proposed. The surface components in the Se3d, In4d and Cu3d emission were attributed to Se dimers or In and Cu adatoms respectively. The x 1 periodicity of the (4 x 1) reconstruction of CuGaSe 2 is

    Full Text Available A rather significant proportion of the Societas Europaeas (the European Company, or SE formed to date have had German roots. German corporate law has been enriched by an interesting alternative which meanwhile seems to have gained momentum. This contribution focuses on SEs incorporated by German entrepreneurs and provides an interesting account concerning the use of SEs in Germany in practice, such as Allianz, Fresenius, BASF and Porsche. Has the SE been used to circumvent rigid company law provisions or is it a more flexible and effective tool, perhaps, for company mobility? The practical motives behind setting up this company form are also reflected upon. These include: the facilitation of cross-border mergers; transfer of the registered office; the ‘European’ image; a more flexible form of co-determination in large companies (reduction of the number of supervisory board members; avoidance and freezing of co-determination for medium-sized enterprises; the appeal of the one-tier system and its endangerment by German co-determination; and flat and uniform structures for company groups. The author also briefly discusses some of the problems arising from the formation of SEs in Germany. He ultimately concludes that practice has shown that it is possible to work with the legal regime of the SE in Germany, which adds a new company form to those available in that Member State.

  18. Forming Glasses from Se and Te

    2009-10-01

    Full Text Available Despite being close neighbors on the Periodic Table, selenium and tellurium present a totally different abilities to form glasses. Se is a very good glass former, and gives rise to numerous glass compositions which are popular for their transparency in the infrared range and their stability against crystallization. These glasses can be shaped into sophisticated optical devices such as optical fibers, planar guides or lenses. Nevertheless, their transparencies are limited at about 12 μm (depending on the thickness of the optical systems due to the relatively small mass of the Se element. On the other hand, tellurium is heavier and its use in substitution for Se permits to shift the IR cutoff beyond 20 μm. However, the semimetallic nature of Te limits its glass formation ability and this glass family is known to be unstable and consequently has found application as phase change material in the Digital Versatile Disk (DVD technology. In this paper, after a review of selenide glasses and their applications, it will be shown how, in a recent past, it has been possible to stabilize tellurium glasses by introducing new elements like Ga or I in their compositions.

    2016-07-01

    Full Text Available SNPMClust is an R package for genotype clustering and calling with Illumina microarrays. It was originally developed for studies using the GoldenGate custom genotyping platform but can be used with other Illumina platforms, including Infinium BeadChip. The algorithm first rescales the fluorescent signal intensity data, adds empirically derived pseudo-data to minor allele genotype clusters, then uses the package mclust for bivariate Gaussian model fitting. We compared the accuracy and sensitivity of SNPMClust to that of GenCall, Illumina's proprietary algorithm, on a data set of 94 whole-genome amplified buccal (cheek swab DNA samples. These samples were genotyped on a custom panel which included 1064 SNPs for which the true genotype was known with high confidence. SNPMClust produced uniformly lower false call rates over a wide range of overall call rates.

    The mourning dove (Zenaidura macroura) call-count survey is a nationwide audio-census of breeding mourning doves. Recent analyses of the call-count routes have utilized a stratification based upon physiographic regions of the United States. An analysis of 5 years of call-count data, based upon stratification using potential natural vegetation, has demonstrated that this uew stratification results in strata with greater homogeneity than the physiographic strata, provides lower error variance, and hence generates greatet precision in the analysis without an increase in call-count routes. Error variance was reduced approximately 30 percent for the contiguous United States. This indicates that future analysis based upon the new stratification will result in an increased ability to detect significant year-to-year changes.

    Templeton, Christopher N.; Greene, Erick

    2007-01-01

    Many animals recognize the alarm calls produced by other species, but the amount of information they glean from these eavesdropped signals is unknown. We previously showed that black-capped chickadees (Poecile atricapillus) have a sophisticated alarm call system in which they encode complex information about the size and risk of potential predators in variations of a single type of mobbing alarm call. Here we show experimentally that red-breasted nuthatches (Sitta canadensis) respond appropriately to subtle variations of these heterospecific “chick-a-dee” alarm calls, thereby evidencing that they have gained important information about potential predators in their environment. This study demonstrates a previously unsuspected level of discrimination in intertaxon eavesdropping. PMID:17372225

Total 456 patients (326 males and 130 females) were attended by on-call general surgery team during 30 emergency days. Most of the calls, 191 (41.9%) were received from 8 am to 5 pm. 224 (49.1%) calls were of abdominal pain, with acute appendicitis being the most common specific pathology in 41 (9.0%) patients. Total 73 (16.0%) calls were received for trauma. Total 131 (28.7%) patients were admitted in the surgical unit for urgent operation or observation while 212 (46.5%) patients were discharged from A and E. 92 (20.1%) patients were referred to other units with medical referral accounts for 45 (9.8%) patients. Total 104 (22.8%) emergency surgeries were done and the most common procedure performed was appendicectomy in 34 (32.7%) patients. Major workload of on-call surgical emergency team is dealing with the acute conditions of abdomen. However, significant proportion of patients are suffering from other conditions including trauma that require a holistic approach to care and a wide range of skills and experience. These results have important implications in future healthcare planning and for the better training of general surgical residents.

    The structural and optical properties of the chalcopyrite CunGanSe2n and CunInnSe2n nanoclusters (n = 2, 4, 6, and 8) are investigated as a function of the size using a combination of basin-hopping global optimization and time-dependent density functional theory. Although the lowest energy structures are found to show almost random geometries, the band gaps and absorption spectra still are subject to systematic blue shifts for decreasing cluster size in the case of CunGanSe2n, indicating strong electron confinement. The applicability of the nanoclusters in photovoltaics is discussed. © 2015 American Chemical Society.

    Thinning of CdSe nanowires (NWs) with controllable size was achieved by a simple acid treatment and subsequent annealing on thick CdSe NWs synthesized from vapour phase growth. During acid treatment, not only the undesired impurities such as native oxides of Cd and Se could be etched, but surface reactions of CdSe NWs were also observed, resulting in the formation of a layer of elemental Se around a thinner CdSe core. As a result, a heterostructure of Se - CdSe nanostructure formed after acid treatment of CdSe NWs. Upon thermal annealing, the Se shell was effectively removed and thinned stoichiometric single-crystalline CdSe NWs could be obtained. It was observed that NWs could be thinned by up to {approx}60% in diameter by acid treatment and subsequent Se thermal desorption. The degree of thinning was controllable by adjusting the duration of acid treatment. The success of the thinning of CdSe NWs by simple acid treatment and the annealing process reported here opens a new processing route for obtaining stoichiometric CdSe NWs with controllable size reduction and improved aspect ratio. This can undoubtedly broadly improve the range of applications of 1D CdSe nanostructures and allow more exploration of their uni-directional properties. A correction was made to the last paragraph of section 3 on 18 September 2007. The corrected electronic version is identical to the print version.

  5. Leveraging Call Center Logs for Customer Behavior Prediction

    Science.gov (United States)

    Parvathy, Anju G.; Vasudevan, Bintu G.; Kumar, Abhishek; Balakrishnan, Rajesh

    Most major businesses use business process outsourcing for performing a process or a part of a process including financial services like mortgage processing, loan origination, finance and accounting and transaction processing. Call centers are used for the purpose of receiving and transmitting a large volume of requests through outbound and inbound calls to customers on behalf of a business. In this paper we deal specifically with the call centers notes from banks. Banks as financial institutions provide loans to non-financial businesses and individuals. Their call centers act as the nuclei of their client service operations and log the transactions between the customer and the bank. This crucial conversation or information can be exploited for predicting a customer’s behavior which will in turn help these businesses to decide on the next action to be taken. Thus the banks save considerable time and effort in tracking delinquent customers to ensure minimum subsequent defaulters. Majority of the time the call center notes are very concise and brief and often the notes are misspelled and use many domain specific acronyms. In this paper we introduce a novel domain specific spelling correction algorithm which corrects the misspelled words in the call center logs to meaningful ones. We also discuss a procedure that builds the behavioral history sequences for the customers by categorizing the logs into one of the predefined behavioral states. We then describe a pattern based predictive algorithm that uses temporal behavioral patterns mined from these sequences to predict the customer’s next behavioral state.

  6. Responses of squirrel monkeys to their experimentally modified mobbing calls

    Fichtel, Claudia; Hammerschmidt, Kurt

    2003-05-01

    Previous acoustic analyses suggested emotion-correlated changes in the acoustic structure of squirrel monkey (Saimiri sciureus) vocalizations. Specifically, calls given in aversive contexts were characterized by an upward shift in frequencies, often accompanied by an increase in amplitude. In order to test whether changes in frequencies or amplitude are indeed relevant for conspecific listeners, playback experiments were conducted in which either frequencies or amplitude of mobbing calls were modified. Latency and first orienting response were measured in playback experiments with six adult squirrel monkeys. After broadcasting yaps with increased frequencies or amplitude, squirrel monkeys showed a longer orienting response towards the speaker than after the corresponding control stimuli. Furthermore, after broadcasting yaps with decreased frequencies or amplitude, squirrel monkeys showed a shorter orienting response towards the speaker than after the corresponding manipulated calls with higher frequencies or amplitude. These results suggest that changes in frequencies or amplitude were perceived by squirrel monkeys, indicating that the relationship between call structure and the underlying affective state of the caller agreed with the listener's assessment of the calls. However, a simultaneous increase in frequencies and amplitude did not lead to an enhanced response, compared to each single parameter. Thus, from the receiver's perspective, both call parameters may mutually replace each other.

    Full Text Available This research aims to define a sustainable resource in Computer-Assisted Language Learning (CALL. In order for a CALL resource to be sustainable it must work within existing educational curricula. This feature is a necessary prerequisite of sustainability because, despite the potential for educational change that digitalization has offered since the nineteen nineties, curricula in traditional educational institutions have not fundamentally changed, even as we move from a pre-digital society towards a digital society. Curricula have failed to incorporate CALL resources because no agreed-upon pedagogical language enables teachers to discuss CALL classroom practices. Systemic Functional Grammar (SFG can help to provide this language and bridge the gap between the needs of the curriculum and the potentiality of CALL-based resources. This paper will outline how SFG principles can be used to create a pedagogical language for CALL and it will give practical examples of how this language can be used to create sustainable resources in classroom contexts.

    Differential cross sections for neutron elastic and inelastic scattering from {sup 76}Se, {sup 78}Se, {sup 80}Se and {sup 82}Se, have been measured at 8-MeV incident neutron energy and from {sup 76}Se and {sup 82}Se at 6- and 10-MeV incident energies. The differences observed in the elastic scattering cross sections are interpretable as the effects of isospin term in the scattering potentials. A full analysis of the elastic scattering data are presented.

    EXAFS functions had been extracted from measurements on the K edge of Se at different temperatures between 20 and 300 K. The analysis of the EXAFS of the filtered first two shells has been done in the wavevector range laying between 2 and 15.5 A -1 in terms of the cumulants of the effective distribution of distances. The cumulants C 3 and C 4 obtained from the phase difference and the amplitude ratio methods have shown the anharmonicity in the vibrations of atoms around their equilibrium position.

    Thermoelectric power of InSe samples doped with tin has been measured as functions of the doping concentration in the range of 0.01 to 10% Sn and of the temperature in the range of 50 to 550 K. In the low temperature range the results obtained are coherent with the two-dimensional behaviour of electrons proposed by other authors. About 100 K the results can be explained successfully by introducing the same scattering mechanisms used to interpret the temperature dependence of the electron mobility

    2016-08-10

    Semiconductor quantum rings are of great fundamental interest because their non-trivial topology creates novel physical properties. At the same time, toroidal topology is difficult to achieve for colloidal nanocrystals and epitaxially grown semiconductor nanostructures. In this work, we introduce the synthesis of luminescent colloidal CdSe nanorings and nanostructures with double and triple toroidal topology. The nanorings form during controlled etching and rearrangement of two-dimensional nanoplatelets. We discuss a possible mechanism of the transformation of nanoplatelets into nanorings and potential utility of colloidal nanorings for magneto-optical (e.g., Aharonov-Bohm effect) and other applications.

    We have fabricated wire structures with (sub)micron sizes in the charge-density wave conductor NbSe 3 . Electrical transport measurements include complete mode-locking on Shapiro steps and show that the patterning has not affected the CDW material. Our mesoscopic wires show strong fluctuation and hysteresis effects in the low-temperature current-voltage characteristics, as well as a strong reduction of the phase-slip voltage. This reduction can not be explained with existing models. We suggest that single phase-slip events are responsible for a substantial reduction of the CDW strain in micron-sized systems. (orig.)

    CuInSe2 powders were synthesized by solvothermal method, and then the CuInSe2/In2Se3 bulk samples were fabricated by spark plasma sintering (SPS) technique. To investigate the phase composition, the powders were determined by X-ray diffraction (XRD). The microstructures of the powders and bulk samples were observed by scanning electron microscopy (SEM). The transportation of the electronic properties and thermal conductivity were measured at room temperature to 700 K. According to the results, the CuInSe2 powders appeared in flower-like patterns which ranged from 3 μm to 6 μm. CuInSe2 powders were synthesized at 180∘C with a chalcopyrite structure. The Seebeck coefficient increased significantly in composite thermoelectric materials up to 200μVṡK-1 at 623 K. The thermal conductivity of the sample significantly decreases from the room temperature to 700 K. The CuInSe2 bulk composite by solvothermal method achieves the highest ZT value of 0.187 at 700 K.

Although there is vast amounts of literature discussing patient communication with their health care providers, few studies have explored patients’ perceptions concerning call light use and communication. The specific aim of this study was to solicit patients’ perceptions regarding their call light use and communication with nursing staff. Methods: Patients invited to this study met the following inclusion criteria: proficient in English, been hospitalized for at least 24 hours, aged ≥21 years, and able to communicate verbally (eg, not intubated. Thirty participants provided written informed consent, were enrolled in the study, and completed interviews. Results: Using qualitative descriptive methods, five major themes emerged from patients’ perceptions (namely; establishing connectivity, participant safety concerns, no separation: health care and the call light device, issues with the current call light, and participants’ perceptions of “nurse work”. Multiple minor themes supported these major themes. Data analysis utilized the constant comparative methods of Glaser and Strauss. Discussion: Findings from this study extend the knowledge of patients’ understanding of not only why inconsistencies occur between the call light and their nurses, but also why the call light is more than merely a device to initiate communication; rather, it is a direct conduit to their health care and its delivery. Keywords: nurse–patient communication, medical technology, quality of care, qualitative research

    Dash, S.; Ravindren, S.; Boolchand, P.

    A universal feature of glasses is the stretched exponential relaxation, f (t) = exp[ - t / τ ] β . The model of diffusion of excitations to randomly distributed traps in a glass by Phillips1 yields the stretched exponent β = d[d +2] where d, the effective dimensionality. We have measured the enthalpy of relaxation ΔHnr (tw) at Tg of Se glass in modulated DSC experiments as glasses age at 300K and find β = 0.43(2) for tw in the 0 Se100-x glasses as x increases to 20%, the length of the polymeric Sen chains between the Ge-crosslinks decreases to n = 2. and the striking relaxation effects nearly vanish.

    Mobile phone use is increasing but there is also concern for adverse health effects. Well-designed prospective studies to assess several health outcomes are required. In designing a study of mobile phone use, it is important to assess which factors need to be considered in classifying the exposure to radiofrequency fields (RF). A pilot study was performed in Sweden and in the UK 2002 to 2003 to test the feasibility of recruiting a cohort of mobile phone users from a random population sample and from mobile phone subscription lists for a prospective study. As one part of this pilot study, different factors were evaluated regarding possible influence on the output power of the phones. By local switch logging, information on calls made from predefined subscriptions or dedicated handsets were obtained and the output power of phones during calls made indoors and outdoors, in moving and stationary mode, and in rural as well in urban areas were compared. In this experiment, calls were either 1, 1.5 or 5 min long. The results showed that high mobile phone output power is more frequent in rural areas whereas the other factors (length of call, moving/stationary, indoor/outdoor) were of less importance. Urban and rural area should be considered in an exposure index for classification of the exposure to RF from mobile phones and may be assessed by first base station during mobile phone calls or, if this information is not available, possibly by using home address as a proxy.

    Off-hours medical care in hospitals is provided by residents, while attendings on call are available for assistance. This study evaluated the gap between residents' expectations and professional guidelines' requirements of attendings on call and what actually occurs during night shifts, while comparing surgical and medical specialties. Two questionnaires based on professional guidelines were filled by residents. The first queried about residents' expectations of attendings on call, and the second asked about communication with the attendings during actual night shifts. While 91 (100%) of residents expected the attending on call to be available by phone during the shift, only 44 (48%) expected the attending to initiate contact, and only 17 (19%) expected the attending to visit the ward or emergency department (ED) without being requested to do so. In 127 shifts (84%), some form of communication occurred. Residents called their attendings during 105 shifts (70%). However, attendings initiated contact with residents at the beginning or during the shift in only 67 (44%) and 62 (41%) shifts, respectively, and initiated a visit to the ward/ED during the shift in only 41 cases (27%). Surgical attendings initiated contact in these three ways significantly more frequently than medical attendings [21 (28%) versus 46 (61%), 20 (26%) versus 42 (56%) and 4 (5%) versus 37 (50%), respectively; P communication during night shifts between residents and attendings occurs in most shifts, attendings initiate far less contact with residents than is required by the guidelines. © 2013 John Wiley & Sons Ltd.

    Italian Poison Centers answer to approximately 100,000 calls per year. Potentially, this activity is a huge source of data for toxicovigilance and for syndromic surveillance. During the last decade, surveillance systems for early detection of outbreaks have drawn the attention of public health institutions due to the threat of terrorism and high-profile disease outbreaks. Poisoning surveillance needs the ongoing, systematic collection, analysis, interpretation, and dissemination of harmonised data about poisonings from all Poison Centers for use in public health action to reduce morbidity and mortality and to improve health. The entity-relationship model for a Poison Center relational database is extremely complex and not studied in detail. For this reason, not harmonised data collection happens among Italian Poison Centers. Entities are recognizable concepts, either concrete or abstract, such as patients and poisons, or events which have relevance to the database, such as calls. Connectivity and cardinality of relationships are complex as well. A one-to-many relationship exist between calls and patients: for one instance of entity calls, there are zero, one, or many instances of entity patients. At the same time, a one-to-many relationship exist between patients and poisons: for one instance of entity patients, there are zero, one, or many instances of entity poisons. This paper shows a relational model for a poison center database which allows the harmonised data collection of poison centers calls.

    Full Text Available The object was to design part of a new building which had been seriously damaged during the war, so that the old and new parts would blend into a pleasant whole, with a capacity for 600 girls. The new designs avoid the glass box style of school buildings, and glass walls have been adopted only on the ground floor, thus giving an impression of light and airiness to what used to be a partial basement. Classrooms have been designed in a simple manner, and give the impression of conventional rooms. Simple lines and materials have been chosen throughout. Strong contrasts in the external finish have been avoided, and colours provide a relaxing background to the intensive activities of the students. A constructional feature is the use of prefabricated concrete joists and supports. Outer walls consist of brick panels filling in the space between the visible concrete framework. Ceilings are of insulating boards, and the floors are covered with linoleum. Special attention has been devoted to the hall. In this case the roof is of white gypsum, and the only features are the grills covering the fluorescent lighting. The walls of this hall are of glass, and are covered with heavy velvet curtains. A balcony with hardwood posts adds a simple and friendly feature to the building. The furniture and drapery have been carefully chosen. Camden school has a rigid tradition of individualism and fine education, and the new building has succeeded in maintaining the exclusive quality of the older parts, as well as offering an overall impression of up to date construction.El problema consistía en proyectar un nuevo núcleo para un edificio que había sido seriamente bombardeado durante la guerra, de tal modo que las partes antiguas y nuevas formasen un conjunto agradable y con capacidad para más de 600 chicas.

    The chemical modification of polycrystalline CuInSe 2 absorber surfaces by the so-called Cd partial electrolyte (PE) treatment was studied by synchrotron X-ray photoelectron spectroscopy (SXPS). The Cd PE treatment was found to remove surface indium oxides and hydroxides and segregated sodium compounds. A hydroxide-terminated CdSe surface layer of one monolayer thickness is formed by the partial electrolyte treatment. The reaction mechanism is discussed as substrate site-controlled exchange reaction, where surface indium is removed and replaced by cadmium. Electronically, the Cd PE treated surface is inverted and exhibits a surface barrier which is by 0.2 eV higher than a comparable structure that was prepared by the vacuum deposition of one monolayer of CdS onto clean CuInSe 2

    Highlights: → CuInSe 2 phase increased gradually accompanied with a decrease in γ-In 2 Se 3 and no intermediate phase during calcination. → CuInSe 2 formation from Cu 2 Se and In 2 Se 3 powders follows a one-dimensional diffusion-controlled reaction with apparent activation energy of about 122.5 kJ/mol. → The solid reaction kinetics may be dominated by the diffusion of In 3+ ions. - Abstract: The reaction mechanism and CuInSe 2 formation kinetics using a solid state reaction from Cu 2 Se and In 2 Se 3 powders synthesized using a heating up process were investigated using X-ray diffractomy (XRD) and transmission electron microscopy (TEM). It was observed that the CuInSe 2 phase increased gradually, accompanied with a decrease in γ-In 2 Se 3 with no intermediate phase as the calcination temperature and soaking time were increased. The reaction kinetics was analyzed using the Avrami and polynomial kinetic model, suggesting that CuInSe 2 formation from Cu 2 Se and In 2 Se 3 powders follows a diffusion-controlled reaction with an apparent activation energy of about 122.5-182.3 kJ/mol. Cu 2 Se and In 2 Se 3 phases react and directly transform into CIS without the occurrence of any intermediate phase and the size of the newly formed CuInSe 2 crystallites was close to that of the Cu 2 Se reactant particle based on the TEM results, which indicated that the solid reaction kinetics may be dominated by the diffusion of In 3+ ions.

    Differential cross sections and vector analyzing powers were measured at an incident deuteron energy of 12.5 MeV for the 76 78 80 82 Se(d,p) 77 79 81 83 Se reactions. The data are compared with the predictions of the DWBA theory to determine the l-value, spin, parity and spectroscopic factor of the resolved states. High resolution measurements were made with a 100 cm broad-range magnetic spectrograph to determine the excitation energies of the states studied, and the possible existence of contaminants in the targets. Definitive spin and parity assignments are made to 16 states in 77 Se, 22 states in 79 Se, 17 states in 81 Se, and 18 states in 83 Se, fifteen of which were previously assigned. In addition, tentative spin assignments were made to one state in 83 Se. The spectrograph measurements allowed the determination of the excitation energies of anumber of additional states in each isotope. Among the 76 states studied in this work, ther are 8 2P/sub 3/2/ states, 4 1F/sub 5/2/ states 6 2P/sub 1/2/ states 4 1G/sub 9/2/ states, 31 2D/sub 5/2/ states, 10 3S/sub 1/2/ states, and 13 2D/sub 3/2 states. A sum-rule analysis was made and the results compared to previous work and to the predictions of the simple pairing theory

In January 1998, the division leader set up the 'call-for-tender co-ordination office' to check and approve each technical document leaving the division. The mandate of the call-for-tender co-ordination office is to check the quality of the documents, in order for these documents to be as clear as possible in terms of both content and structure. The role of this office is to contribute positively and give service to the people writing the documents, and not to give negative criticism. The aim of this paper is to present the mandate of the office, how papers are processed, and to draw up a first result summary.

    Full Text Available The aim of this study was to investigate the relationship between six characteristics of call centre work environments, burnout, affective commitment and turnover intentions. These characteristics were competing management goals, work overload, electronic performance monitoring, lack of career opportunities, lack of skill variety and emotional labour. A convenient sample of employees (N = 146 was obtained from a call centre. Multiple regression analysis showed that work overload, lack of career opportunities, skill variety and emotional labour were the most important predictors of burnout. Burnout had a direct effect on turnover intentions. Affective commitment partially mediated the relationship between burnout and turnover intention.

  19. Basket call option pricing for CCVG using sparse grids

    The use of processes with jumps to overcome the shortcomings of the classical Black and Scholes when modelling stock prices has became very popular. One of the best-known models is the Common Clock Variance Gamma model (CCVG), introduced by Madan and Seneta in the 1990 [3]. We propose a method to price European basket call options modelled by the CCVG. The method could be extended to other model obtained by the subordination of a multidimensional Brownian motion and to more general options. To simplify the expositions we consider calls under the CCVG.

    Executing application function calls in response to an interrupt including creating a thread; receiving an interrupt having an interrupt type; determining whether a value of a semaphore represents that interrupts are disabled; if the value of the semaphore represents that interrupts are not disabled: calling, by the thread, one or more preconfigured functions in dependence upon the interrupt type of the interrupt; yielding the thread; and if the value of the semaphore represents that interrupts are disabled: setting the value of the semaphore to represent to a kernel that interrupts are hard-disabled; and hard-disabling interrupts at the kernel.
