    Full Text Available Este trabalho teve como objetivo avaliar em escalas espacial (vertical e horizontal e temporal as características limnológicas do Reservatório Rio das Pedras (Complexo Billings, São Bernardo do Campo, SP – Brasil. Nos meses de março e outubro de 2004 foram amostradas em perfil três estações no reservatório. As variáveis analisadas foram: temperatura, condutividade elétrica e pH, com sonda multiparâmetros; concentrações de amônio, nitrito, nitrato, fosfato, ortosilicato, fósforo total, clorofila-a e feofitina, por método espectrofotométrico; oxigênio dissolvido por método titulométrico; além das concentrações de sólidos totais e material em suspensão. Para análise estatística dos dados foi aplicada a ACP (Análise de Componentes Principais. A heterogeneidade temporal observada foi conseqüência das diferenças de temperatura, que geraram estratificação térmica, química e biológica, no mês de março. As diferenças espaciais verticais também resultaram da estratificação térmica. As maiores discrepâncias das características limnológicas, em relação ao padrão de distribuição espacial horizontal, foram obtidas na estação 1, e são diretamente relacionadas à influência das águas provenientes do reservatório Billings. De acordo com a CONAMA 357/05, para o mês de outubro de 2004 as águas do reservatório estão em conformidade com a Classe 3. Para o mês de março, na estação 3 os valores estão abaixo do estabelecido, conferindo não conformidade para a Classe 3.

    Full Text Available Este artigo analisa se, entre 1996 e 2010, a execução por parte do Executivo das emendas individuais de deputados federais ao orçamento aproximou esses parlamentares das preferências do governo nas votações nominais. Os argumentos que enxergam componente não partidário, personalista e paroquial no apoio parlamentar ao Executivo inspiram-se na influência dessas emendas. No entanto, tanto sua defesa como sua refutação deixam lacunas importantes que mantêm aberta a questão, pois ou desconsideraram o fator tempo nos testes realizados ou seu tratamento metodológico necessita correções. Buscamos superar esses problemas verificando se a distância entre pontos ideais dos parlamentares e da indicação do líder do governo, em dado ano, é influenciada pelas emendas orçamentárias executadas tanto naquele ano como nos anteriores. Propomos modelar tal defasagem temporal entre emendas e apoio parlamentar, corrigindo autocorrelação serial, controlando por medidas de pertencimento à coalizão e lidando com os inerentes problemas de instrumentalização desses modelos.

    Full Text Available The objective of the present study was to evaluate spatial and temporal patterns of limnological characteristics of the Rio das Pedras Reservoir (Billings Complex, São Bernardo do Campo, São Paulo – Brazil. Profile samples were taken at three stations during two periods (March and October, 2004. The variables analyzed were: temperature, electrical conductivity, pH, with multiparameter probe; concentration of ammonium, nitrite, nitrate, phosphate, orthosilicate, total phosphorus, chlorophyll-a and phaeophytin, by spectrophotometric method; dissolved oxygen by titrimetric method; beyond concentrations of total solids and suspended material. PCA (Principal Components Analyses was applied for the statistical analyses. The temporal heterogeneity observed was a consequence of differences in temperature observed in the month of March, which generated thermal, chemical and biological stratification. The vertical spatial differences also resulted from the thermal stratification. The largest discrepancies in the limnological characteristics, in relation to the pattern of horizontal spatial distribution, were obtained in station 1, and are directly related to the influence of the incoming waters of the Billings reservoir. According to CONAMA 357/05, for the month of October, 2004, the waters of the reservoir were in accordance with Class 3. In March, the values for station 3 were below the standards established, indicating non-conformity with Class 3.

    Full Text Available O estudo da distribuição temporal de chuvas é realizado com objetivo de caracterizar o padrão de chuva mais frequente. O conhecimento das características físicas das chuvas com relação aos padrões de precipitação permite realizar modelagem matemática de eventos hidrológicos em condições mais próximas às condições reais. O objetivo deste trabalho foi caracterizar as chuvas erosivas em Urussanga, SC, com relação aos padrões hidrológicos de distribuição temporal. Foram usados os pluviogramas da estação meteorológica de Urussanga (latitude 28,31º S, longitude 49,19º W e altitude de 49 m relativos ao período de outubro de 1980 a março de 2012. As chuvas erosivas foram classificadas em padrões avançado, intermediário e atrasado, se a maior intensidade ocorre no terço de duração inicial, intermediário e final, respectivamente. Foram determinadas as características de altura pluvial, duração da chuva, energia cinética, intensidade máxima em 30 min, erosividade e frequência de chuvas mensais de cada padrão de chuva. Verificou-se a ocorrência de 1.221 chuvas erosivas, das quais 651 com perfil avançado; 416, intermediário; e 154, atrasado. A duração média das chuvas erosivas é de 14,4 h. A média total de intensidade média para as chuvas erosivas foi de 17,4 mm h-1. A maior concentração de chuvas (32,9 % foi observada no intervalo de duração de 6 a 12 h. Para duração inferior a 18 h, ocorre maior frequência de chuvas do padrão avançado; já para acima de 18 h, as frequências de chuvas do padrão avançado e intermediário são semelhantes.

    Full Text Available The progress of epilepsies diagnosis has been great, but, amongst the diagnostic detailing that demand research, one of the most important is the essential lateralization and localization of epileptogenic zone, considered as the cerebral cortex region, that removed, will result in a free state of seizures. The present study aims to analyze the possible uses of proton spectroscopy for clinical and pre-surgical evaluation of focal extratemporal epilepsies, since this group presents the highest difficulty degree for lateralizing and locating epileptogenic zones. In almost all cases, a non invasive diagnosis can be performed using routine electroencephalography, video-electroencephalography - considered as gold standard, and magnetic resonance imaging. However, when the results of these exams are contradictory, some patients need invasive techniques, as the intra-cranial video-EEG, using deep electrodes, sub-dural strip and grid, that are associated with increased diagnostic cost and risk of complications, as cerebral hemorrhages and intra-cranial infections. Proton spectroscopy appears as a possibility, given its capacity to evaluate cerebral metabolism, by N-acetyl-aspartate (NAA, creatine (Cre and choline (Cho concentrations, amongst other metabolites. This non invasive method may provide time reduction of this evaluation and reliable level improvement for this topographical diagnosis.Tem sido grande o progresso no diagnóstico das epilepsias, mas dentre os detalhamentos diagnósticos a exigir pesquisas, estão a lateralização e a localização precisas da zona epileptogênica, considerada como a região do córtex cerebral que, removida, irá resultar num estado livre de crises. Por meio de revisão da literatura, o objetivo deste estudo é expor e analisar os métodos diagnósticos das epilepsias neocorticais extratemporais, dadas as características que as tornam mais complexas do que as epilepsias temporais visto que estas apresentam o

    Full Text Available OBJETIVO: Analisar o padrão temporal dos óbitos e internações, no período de 1995 a 1998, associadas à diarréia em crianças menores de cinco anos de idade para subsidiar ações específicas de prevenção e controle dessa doença. MÉTODOS: Os dados foram obtidos do Sistema de Informações sobre Mortalidade (SIM e Sistema de Internações Hospitalares (SIH do Ministério da Saúde. As séries mensais de internações e de óbitos por diarréia foram decompostas em componentes de tendência linear estocástica, sazonalidade determinística e irregularidades mediante a aplicação dos modelos estruturais para análise de séries temporais. RESULTADOS: Os níveis de ambas as séries apresentaram mudanças ao longo do tempo, com declínio mais perceptível na série de internações. A variação das taxas de inclinação foi constante para cada uma das séries, em média, a menos 5,3 internações por mês (p-valor <0,001 e menos um óbito por mês (p-valor <0,1, respectivamente. Na análise dos resíduos do modelo de internações, observou-se mudança no nível da tendência em janeiro de 1996. O componente sazonal de ambos os modelos foi estatisticamente significante (p-valor <0,0001, sendo maio e junho os meses com maior excesso de internações e óbitos. Os pressupostos de normalidade e de independência temporal dos resíduos não puderam ser rejeitados ao nível de 0,05. CONCLUSÕES: Os resultados sugerem a predominância da etiologia viral das diarréias moderadas e graves. Neste caso, a vacinação específica é a medida mais eficaz na prevenção e controle, sendo necessários estudos de eficácia de novas candidatas à vacina contra o rotavírus no Brasil.

    Full Text Available Avaliou-se a dinâmica espacial e temporal do uso do solo na microbacia que contém a nascente do Rio São Lourenço, situada no bioma Cerrado. Foram utilizadas imagens orbitais obtidas pelo sensor Mapeador Temático (TM do Landsat 5, referentes à órbita/ponto 226/71 dos anos de 1985, 1997 e 2011, com resolução espacial de 30 metros, compreendendo um período de 26 anos. O mapa de uso das terras foi gerado a partir de classificação supervisionada, utilizando o algoritmo Máximo Verossimilhança. O Índice de vegetação por diferença normalizada (NDVI foi gerado a partir das bandas 4 e 3 correspondentes ao infravermelho próximo e ao vermelho, respectivamente. Verificou-se que mais de 78% da área da microbacia é destinada à agricultura. A classe floresta aumentou no decorrer dos anos analisados, fato este explicado pelo plantio de floresta de eucalipto, no setor norte da microbacia. O NDVI evidenciou áreas que estavam com pouca biomassa vegetal, diferenciando-as das áreas com cobertura vegetal densa. Considerando o NDVI de uma área em processo de recuperação ambiental, denominada de unidade demonstrativa de restauração ecológica, observou-se que com nove meses de implantação, a mesma ainda não apresenta resposta espectral semelhante à mata ciliar adjacente. As matas ciliares da microbacia representam potenciais corredores de dispersão de fluxo biológico, que conectam áreas de planalto situadas no bioma Cerrado à planície sedimentar do Pantanal situada no sudoeste de Mato Grosso. A pesquisa fornece subsídios para a adequação ambiental das propriedades rurais junto à legislação ambiental pertinente.

Water samples were collected monthly from October/1996 to October/1997 for turbidity, electric conductivity, pH, alkalinity, dissolved oxygen, nutrients, biomass, and algal phenology analysis. Spatial distribution pattern of algal biomass showed that all four sampling stations were similar among themselves during the whole study period. Regarding the temporal variation, greatest algal total biomass values (98.35-266.06 g.m-2 were measured during the rainy period whereas the smallest ones (48.86-170.56 g.m-2 were detected during the dry period. Algal population density peaked at all four sampling stations from October/1996 to April/1997 (rainy period when the greatest values of air and water temperature, precipitation, solar radiation, turbidity, total nitrogen, and ammonium were measured allowing favorable conditions for the algal growth. Period from May/1997 (late fall to October/1997 (early spring was favorable to the development of reproductive structures (nucules and globules with consequent decrease of algal biomass and population density, clearly suggesting the greatest energy allocation towards the development of sexual reproductive structures. This fact was confirmed by the canonic correspondence analysis that indicated strong correlation between nucules length and width, number of nucules per plant, and oospores length and width with the low values of pH and high ones of dissolved inorganic matter detected during the dry period. Consequently, environmental factors such as increasing of water temperature and nutrients availability

    Full Text Available OBJETIVO: Avaliar os resultados preliminares da técnica de epifisiodese temporária utilizando-se as placas de Sherman no tratamento de distúrbios e deformidades dos membros inferiores. MÉTODOS: Foram avaliados, retrospectivamente, 27 pacientes submetidos à epifisiodese temporária do fêmur distal ou tíbia proximal com as placas de Sherman, em um total de 28 procedimentos. A idade média no momento da cirurgia foi de 11,2 anos (3-15 anos. Os implantes de dois furos eram confeccionados em liga de aço e apresentavam um orifício central para ser utilizado como guia. A fixação foi feita com dois parafusos canulados de 3,5mm. As indicações para o tratamento foram os desvios angulares dos membros inferiores em valgo (n = 10, varo (n = 2 e mistos (n = 1; discrepância do comprimento dos membros (n = 9; e contratura em flexo do joelho (n = 5. RESULTADOS: O tempo médio de seguimento foi de 11,78 meses (±4,07. Observamos apenas um evento adverso (migração do implante em um paciente submetido à epifisiodese anterior do fêmur distal para correção de flexo de joelho. Não houve nenhum caso de quebra do material ou fechamento fisário prematuro. CONCLUSÃO: A técnica de epifisiodese temporária com o uso das placas de Sherman mostrou ser de fácil execução e esteve envolvida com um baixo índice de complicações e custo inferior aos implantes similares em titânio.

Houve boa concordância entre a análise visual prospectiva e outra retrospectiva, realizada por dois observadores independentes (C=0,748 e 0,720. Houve também concordância entre a análise retrospectiva dos dois observadores (C=0,733. Houve ainda concordância genuína (C=0,788 entre os resultados das análises quantitativa e qualitativa realizadas prospectivamente. A análise quantitativa demonstrou uma tendência não-significativa a lateralizar mais casos de atrofia hipocampal presumida clinicamente. Nossos resultados confirmam a confiabilidade da análise visual qualitativa e indicam a utilidade da volumetria hipocampal como uma medida suplementar, objetiva e quantitativa, de esclerose hipocampal.

    Full Text Available Os processos de oxirredução influem na reatividade dos óxidos de ferro no solo, o que pode afetar a disponibilidade do fósforo. Com o objetivo de avaliar como estes processos interferem na disponibilidade do fósforo, realizou-se um estudo com seis solos do Uruguai sujeitos a variações temporais nas condições de oxirredução. Amostras do horizonte A desses solos, com diferente material de origem e que ocupam posição topográfica plana e encostas baixas da paisagem, foram colocadas sob condições de alagamento por 5, 15 e 45 dias. Decorridos estes períodos de tempo, os materiais de solo foram secos durante um período de 21 dias e amostrados para análises químicas. As formas de ferro de baixa cristalinidade, extraídas pelo oxalato de amônio a pH 6 (Fe6, aumentaram com o alagamento dos solos e, após a secagem, decresceram, mas ficaram, entretanto, acima dos teores iniciais. Encontrou-se uma relação significativa entre o conteúdo de carbono orgânico dos solos e a proporção de formas de ferro de baixa cristalinidade, antes e depois dos diferentes períodos de alagamento. Os teores de fósforo disponível extraídos por Bray-1 aumentaram com o alagamento e, com exceção do solo Algorta, após a secagem dos solos, diminuíram para valores similares aos iniciais. O alagamento do solo e a posterior secagem determinaram o aumento das frações de ferro de maior reatividade, acarretando a adsorção de fósforo, evidenciado pelos menores teores de fósforo remanescentes na solução. Houve tendência muito definida de diminuição do fósforo na solução dos solos com o aumento dos teores de ferro em formas de alta reatividade química (Fe6. Estes resultados indicam que, após ciclos de alagamento-secagem do solo, a adsorção do fósforo aumenta pela reação com compostos de ferro recentemente precipitados, o que resulta em menor disponibilidade do fósforo para as plantas.

    Distributed Acoustic Sensing (DAS) is creating a "field as laboratory" capability for seismic monitoring of subsurface changes. By providing unprecedented spatial and temporal sampling at a relatively low cost, DAS enables field-scale seismic monitoring to have durations and temporal resolutions that are comparable to those of laboratory experiments. Here we report on seismic processing approaches developed during data analyses of three case studies all using DAS-enabled seismic monitoring with applications ranging from shallow permafrost to deep reservoirs: (1) 10-hour downhole monitoring of cement curing at Otway, Australia; (2) 2-month surface monitoring of controlled permafrost thaw at Fairbanks, Alaska; (3) multi-month downhole and surface monitoring of carbon sequestration at Decatur, Illinois. We emphasize the data management and processing components relevant to DAS-based seismic monitoring, which include scalable approaches to data management, pre-processing, denoising, filtering, and wavefield decomposition. DAS has dramatically increased the data volume to the extent that terabyte-per-day data loads are now typical, straining conventional approaches to data storage and processing. To achieve more efficient use of disk space and network bandwidth, we explore improved file structures and data compression schemes. Because noise floor of DAS measurements is higher than that of conventional sensors, optimal processing workflow involving advanced denoising, deconvolution (of the source signatures), and stacking approaches are being established to maximize signal content of DAS data. The resulting workflow of data management and processing could accelerate the broader adaption of DAS for continuous monitoring of critical processes.

    Full Text Available O objetivo deste estudo foi investigar os efeitos de diferentes padrões respiratórios no desempenho e na organização temporal das braçadas do nado "Crawl" de atletas de elite. Vinte e um jovens atletas do gênero masculino participaram de forma voluntária do estudo. Eles foram filmados nadando 25 m do nado "Crawl", em velocidade máxima, em quatro condições de respiração: inspiração para o lado preferido (LP; para o lado não preferido (LNP; bilateral (B; e, sem respiração (S. Duas filmadoras digitais (60 fps captaram as imagens que foram analisadas através do "software" Kinovea 0.8.7 nos 10 metros centrais do percurso. Para análise foram consideradas medidas de desempenho e de organização temporal das braçadas. Os resultados permitiram concluir que o padrão respiratório afeta o desempenho de atletas jovens de elite. Mostraram que, em termos de velocidade, tempo, frequência e comprimento de braçada, é mais vantajosa a condição de nadar "Crawl" em apneia (S que em qualquer das condições com inspiração (B, LP e LNP. Portanto, o padrão preferido de respiração, não necessariamente, corresponde ao mais eficiente em termos do desempenho. Assim, professores e técnicos de Natação deveriam incentivar a prática e o emprego do padrão em apneia como estratégia tática para nadadores velocistas. Em relação à braçada, os resultados mostraram que diante da modificação do padrão respiratório, nadadores peritos jovens mantêm a estrutura temporal das braçadas direita e esquerda (aspectos invariantes da braçada bem como a coordenação entre os braços inalterada enquanto efetuam ajustes na fase aérea da braçada (aspectos variantes. Assim sendo, atletas jovens de elite apresentam braçada com relativa autonomia frente ao componente respiração e nadam efetuando ajustes considerando a economia de recursos.The aim of this study was to investigate the effects of different breathing patterns on the performance and

    Full Text Available This study was carried out in headwater streams in the Paraguay and Paraná river basins, with bi-monthly samples from January to November 2004, aiming to quantify the influence of environmental factors on the temporal rate of turnover in species composition of the fish communities. The environmental variables explained 73.5% of the variation in beta diversity and 52.5% of the variation in mean dissimilarity. Altitude was the only environmental descriptor that significantly explained the variation in beta diversity and mean dissimilarity in both basins.O presente estudo foi realizado em riachos de cabeceira nas bacias dos rios Paraguai e Paraná, por amostragens bimestrais de janeiro a novembro de 2004, com o objetivo de se quantificar a influência dos fatores ambientais sobre a taxa de alteração temporal na composição de espécies nas comunidades de peixes. As variáveis ambientais utilizadas explicaram 73,5% da variação na taxa de alteração na composição de espécies, utilizando a diversidade beta e 52,5% da variação na taxa de alteração pelo coeficiente de Jaccard. A altitude dos locais amostrados foi o único preditor significativo da taxa de alteração temporal na composição de espécies para ambas as bacias.

    Full Text Available A estabilidade temporal é descrita como a persistência temporal de um padrão espacial e é avaliada pela análise de correlação de medidas em datas sucessivas. Neste trabalho, foi avaliada a armazenagem de água no solo em duas transeções de 76 m cada, contendo 20 pontos em cada uma. em um Latossolo Vermelho-Amarelo argissólico cultivado com citros com 11 anos em Piracicaba/SP. A umidade do solo para determinação da armazenagem, na camada de 0,00-1,10 m, ao longo do tempo, foi obtida com uma sonda de nêutrons, calibrada para o solo em estudo, realizando leituras semanais às profundidades de 0,20, 0,40, 0,60, 0,80, 1,0 e 1,10 m. A armazenagem de água no solo foi determinada utilizando-se o método de Simpson. Os dados da armazenagem média de água no solo nos três anos de estudo mostraram que sua distribuição, ao longo do tempo, apresentou comportamento semelhante e que os coeficientes de correlação linear e de posição de Spearman foram altos entre o ano 1 e o ano 2, o ano 2 e o ano 3 e o ano 1 e o ano 3, indicando existência de estabilidade temporal e persistência temporal significativa do padrão espacial observado. Foi verificada dependência espacial moderada de 17,10 m pelo semivariograma exponencial. Pela técnica da diferença relativa, os pontos que apresentaram comportamento estável no tempo foram o ponto 29, para os anos 1 e 2, e os pontos 16, 29 e 39, para o ano 3, que podem ser usados para estimar com segurança a armazenagem média de água no solo. O ponto 29 foi o que se apresentou estável para os três anos de estudo, sendo, portanto, o mais recomendável tanto para a armazenagem gravimétrica como para a volumétrica.Temporal stability is described as the temporal persistence of a spatial pattern and is evaluated through correlation analysis of successive measurement data.

    Research on the distribution of natural radionuclides in Antarctica is rare and thus, there is great interest in to know their occurrence and factors related to its mobilization, transference and accumulation in this extremely fragile environment. Natural radionuclides have been used intensively as tracers in the ocean, helping to better understand processes as sinking and particle resuspension, water masses mixture and oceanic circulation. {sup 234}Th (t½ = 24.1 days) is a particle-reactive radionuclide produced continuously in seawater by the decay of its soluble precursor conservative with salinity {sup 238}U (t½ = 4.5 10{sup 9} years). Since {sup 234}Th presents relatively short half-life, it is used to quantify processes that occur in temporal scale varying from days to weeks. The disequilibrium {sup 234}Th/{sup 238}U in the surface ocean has been applied to estimate carbon fluxes exported via sinking material. The flux of particles biologically productive out of the euphotic zone in the Southern Ocean has special attention due to its importance in the control of CO{sub 2} atmospheric concentrations. The radionuclides {sup 210}Pb (t½ = 22.3 years) and {sup 210}Po (t½ = 138 days) are also particle-reactive. The disequilibrium {sup 210}Po/{sup 210}Pb has been used to estimate fluxes of particles exported in the ocean in the time scale of weeks. The long-lived Ra isotopes, {sup 226}Ra (t½ = 1,600 years) and {sup 228}Ra (t½ = 5.75 years) are soluble in seawater, presenting unique properties that make them excellent tracers of water masses. This research work had the aim to study the distributions of natural radionuclides {sup 238}U, {sup 234}Th, {sup 22}'6Ra, {sup 22}'8Ra, {sup 210}Pb and {sup 210}Po in the Bransfield Strait during 2 samplings carried out in the 2011 Austral Summer (OPERANTAR XXIX and XXX).

  15. Temporal naturalism

    Science.gov (United States)

    Smolin, Lee

    2015-11-01

    Two people may claim both to be naturalists, but have divergent conceptions of basic elements of the natural world which lead them to mean different things when they talk about laws of nature, or states, or the role of mathematics in physics. These disagreements do not much affect the ordinary practice of science which is about small subsystems of the universe, described or explained against a background, idealized to be fixed. But these issues become crucial when we consider including the whole universe within our system, for then there is no fixed background to reference observables to. I argue here that the key issue responsible for divergent versions of naturalism and divergent approaches to cosmology is the conception of time. One version, which I call temporal naturalism, holds that time, in the sense of the succession of present moments, is real, and that laws of nature evolve in that time. This is contrasted with timeless naturalism, which holds that laws are immutable and the present moment and its passage are illusions. I argue that temporal naturalism is empirically more adequate than the alternatives, because it offers testable explanations for puzzles its rivals cannot address, and is likely a better basis for solving major puzzles that presently face cosmology and physics. This essay also addresses the problem of qualia and experience within naturalism and argues that only temporal naturalism can make a place for qualia as intrinsic qualities of matter.

    Contingency, and more particularly temporal contingency, has often figured in thinking about the nature of learning. However, it has never been formally defined in such a way as to make it a measure that can be applied to most animal learning protocols. We use elementary information theory to define contingency in such a way as to make it a measurable property of almost any conditioning protocol. We discuss how making it a measurable construct enables the exploration of the role of different contingencies in the acquisition and performance of classically and operantly conditioned behavior.

    principais fatores ecológicos relacionados com sua dinâmica. MÉTODOS: As amostras foram coletadas em cinco estações entre julho de 2002 e julho de 2003. As variáveis físicas e químicas foram amostrados mensalmente e a densidade foi estimada a través de coletas realizadas dentro da zona fótica, a taxa de crescimento (r, taxa de rotatividade (T, Tempo de Geração (GT, Largura do nicho (NW, Power Taylor's Law, e a taxa de mudança da população (σs foram utilizados. Análise de Correspondência Canônica (CCA foi usado também. RESULTADOS: A densidade total foi 264.163,4 cel.L-1, a maior foi encontrada em Up Río Chico e a mais baixa na barragem. As espécie foi achada mais agrupada no espaço que no tempo. O valor de r variou entre 0,29 e 0,3 cel.d-1, GT entre 1,8 e 2,4 dias, T entre 0,55 e 0,42 divisões por dia, NW entre 0,58 e 0,72, e σs entre 0,3 e 2,3 d-1. Os três primeiros componentes da CCA explicaram 92,2% da variação. A densidade foi positivamente associado com clorofila a, NH4+, RWCS e direção do vento. A atenuação da luz, NO3-, SiO2 e O2 estiveram associados negativamente com C. furcoides. DISCUSSÃO: C. furcoides é um estrategista tipo S, aumenta sua densidade nos periodos mais quentes perante condições eutróficas, penetração de luz baixa e alta estabilidade térmica. A espécie é independente da temperatura, mas dependente das mudanças na precipitação e nutrientes, - especialmente nitrogênio - não fósforo solúvel. Up Río Chico apresentou as melhores condições para o aumento de C. furcoides, porque esta estação apresentou os mais altos níveis de nitrogênio total e a maior estabilidade relativa. CONCLUSÃO: C. furcoides tem uma ecologia muito semelhante a aquela de C. hirundinella; é um organismo altamente variável nas escalas temporal e espacial, com uma vasta gama de nicho e uma distribuição agregada. Pertence ao Grupo morfo-funcional V e às associações Lo e LM.

    Full Text Available RESUMO As características de uma imagem de Buda são o resultado do processo milenar que uniu três fatores: as mitologias orientais mais antigas que o budismo, sua capacidade de se adequar às crenças locais e as suas próprias reinterpretações. Após o surgimento das primeiras estátuas que representavam o Buda histórico, o ideal de beleza para um ser que alcançou a Iluminação baseou-se nas antigas "ciências" orientais, predominantemente mentais e de energias sutis. Enquanto a estética ocidental discutia as idealizações da arte com racionalidade, ignorando um oriente "pagão e supersticioso", as imagens budistas personificavam estados mentais que o ocidente só cogitaria na sua modernidade. A arte budista transmite o legado ancestral e imutável de chaves místicas da consciência e do equilíbrio..

    Full Text Available Abstract Background The Distributed Annotation System (DAS has proven to be a successful way to publish and share biological data. Although there are more than 750 active registered servers from around 50 organizations, setting up a DAS server comprises a fair amount of work, making it difficult for many research groups to share their biological annotations. Given the clear advantage that the generalized sharing of relevant biological data is for the research community it would be desirable to facilitate the sharing process. Results Here we present easyDAS, a web-based system enabling anyone to publish biological annotations with just some clicks. The system, available at http://www.ebi.ac.uk/panda-srv/easydas is capable of reading different standard data file formats, process the data and create a new publicly available DAS source in a completely automated way. The created sources are hosted on the EBI systems and can take advantage of its high storage capacity and network connection, freeing the data provider from any network management work. easyDAS is an open source project under the GNU LGPL license. Conclusions easyDAS is an automated DAS source creation system which can help many researchers in sharing their biological data, potentially increasing the amount of relevant biological data available to the scientific community.

    and attractive renderings of bright light sources. Based on the anatomy of the human eye, we propose a model that enables real-time simulation of dynamic glare on a GPU. This allows an improved depiction of HDR images on LDR media for interactive applications like games, feature films, or even by adding movement......Glare is a consequence of light scattered within the human eye when looking at bright light sources. This effect can be exploited for tone mapping since adding glare to the depiction of high-dynamic range (HDR) imagery on a low-dynamic range (LDR) medium can dramatically increase perceived contrast....... Even though most, if not all, subjects report perceiving glare as a bright pattern that fluctuates in time, up to now it has only been modeled as a static phenomenon. We argue that the temporal properties of glare are a strong means to increase perceived brightness and to produce realistic...

    Full Text Available The pterional craniotomy is one of the most frequently surgical approaches used in neurosurgery and currently it has become a mainsteam. It allows excellent microsurgical exposure of anterior and posterior regions of the arterial circle of Willis, supra and paraselar regions, the superior orbital fissure of sphenoid bone, cavernous sinus, orbit, temporal lobe, midbrain and the frontal lobe. Like others techniques, the pterional craniotomy presented disadvantages related to dissection of the temporal muscle. From the first fronto lateral craniotomy described by Dandy to expose the optic chiasm and the pituitary we pass through the Yasargil's classical description of craniotomy centered in fronto-temporal sylvian fissure until reaching the recent"minipterional craniotomy", modifications of the pterional craniotomy were proposed to reduce the extra cranial tissue trauma and reduce the area of craniotomy without affecting the exposure of surgical targets, thus improving their aesthetic and functional results. An historical analysis of the frontolateral approaches has demonstrated that they have evolved from larger craniotomies to smaller ones, however only the minipterional craniotomy is able to offer similar surgical exposure.A craniotomia pterional é um dos acessos cirúrgicos mais freqüentemente utilizados. Esta técnica permite excelente exposição microcirúrgica das regiões anterior e posterior do polígono de Willis, regiões supra-selar, fissura orbital superior do osso esfenóide, seio cavernoso, órbita, lobo temporal, mesencéfalo e lobo frontal.

    2013-12-01

    Full Text Available Sven Kommer fragt in seinem Beitrag, inwieweit das Habitus-Konzept als Erklärungsmuster für die beobachtbare Zementierung sozialer Ungleichheit im Schulsystem greift. Dabei konstatiert der Beitrag, dass alle an der Weiterschreibung des Habitus-Konzepts beteiligten AutorInnen sich darin einig sind, dass es wichtige Beiträge für die Selbst-Aufklärung einer weitestgehend mediatisierten Gesellschaft leistet. Der Artikel geht dabei – auch angesichts der PISA-Studien – von dem empirischen Befund aus, dass die individuelle Ausprägung der Medienkompetenz aufs engste mit den Ressourcen des Elternhauses verbunden ist und sich dabei die elterlichen Formen der Medienerziehung unübersehbar mit den aktuellen medialen Handlungspraxen verbinden. Dieser Befund deckt sich auf weite Strecken auch mit den Ergebnissen der Bildungssoziologie Pierre Bourdieus, weshalb die Diskussionen zum medialen Habitus im Rahmen dieser Ausführungen auch mit empirischen Argumenten unterfüttert werden. Ganz in diesem Sinne arbeitet der Artikel auch heraus, dass die aus dem Kontext der Cultural Studies stammenden Thesen zur Nivellierung kultureller Milieu-Unterschiede wenig empirisch fundiert sind. Der Artikel betont dahingehend, dass hier eine unreflektierte Infiltration durch genuin neoliberales Gedankengut vorliegt, da mit ihr auch die Annahme einer "freien Wahl" von Lebensweg, Milieuzugehörigkeit oder Gender verbunden werden kann. Dabei wir auch eingehend der "Clash of Habitus" diskutiert, der zwischen Lehrenden und Lernenden stattfindet und das Augenmerk ein Mal mehr auf die Tatsache lenkt, das unser Bildungssystem auf dieser pädagogisch relevanten Ebene durch soziale Ungleichheiten gekennzeichnet ist. In his essay, Sven Kommer questions whether the notion of habitus is suitable to support the understanding of the obvious consolidation of inequality in the school system. He shows that all authors active in the continued use of the notion of habitus agree that it

    Full Text Available Previous studies suggest that there is an excellent correlation between the morphology and dimensions of ear structures in sheep and human beings. AIM: To analyze and describe the histology of structures inside the temporal bone in sheep. MATERIAL AND METHODS: A total of 307 slides obtained from vertical and horizontal sections of the temporal bone of eight sheep were analyzed. Structures were classified as similar or not similar to human structures, based on cellularity and histological architecture parameters. STUDY DESIGN: Experimental. RESULTS: The study revealed similarities between sheep and humans in terms of type of epithelium, bone component, spaces in the auditory meatus, in addition to a marked histological resemblance of cellularity and that of the structures surrounding the ear. The main differences observed were the presence of an anatomic bulla, the absence of aeration in the mastoid and the inferior opening of the hypotympanum into the bulla in sheep. CONCLUSION: Based on these observations, it is possible to conclude that sheep represent an adequate option for training and research in otologic surgery.Resultados prévios apontam para uma ótima correlação entre a morfologia e as dimensões das estruturas anatômicas de ovelhas e seres humanos.

    Full Text Available Als biochemisches Rezidiv (BCR wird der Wiederanstieg des nach kurativer Therapie des Prostatakarzinoms (PCa abgefallenen PSA-Werts bezeichnet. Der PSA-Verlauf nach kurativer Therapie ist von der primären Behandlungsmethode abhängig, weshalb auch unterschiedliche Definitionen dafür vorliegen. Der Verlauf selbst scheint prognostische Bedeutung zu haben. Ein Wiederanstieg des PSA-Werts geht der klinischen Progression voraus, wodurch frühzeitig eine Therapie eingeleitet werden kann. Der ideale Zeitpunkt für eine Sekundärbehandlung ist allerdings noch ungenügend definiert. Fast die Hälfte der BCR treten innerhalb der ersten 2 Jahre, ¾ innerhalb der ersten 5 Jahre nach Primärtherapie auf. Als Risikofaktoren für einen BCR werden ein primäres Tumorstadium ≥ T2c, PSA 15, Samenblaseninvasion, Lymphknotenbefall sowie Gleason-Score ≥ 8 angesehen. Von klinischer Bedeutung ist vor allem die Unterscheidung zwischen lokoregionärem und systemischem Rezidiv. Hierzu werden als Parameter neben dem primären Tumorstadium und Gleason-Score das posttherapeutische Intervall und die PSA-Dynamik empfohlen. Als diagnostische Maßnahmen erscheinen nur die Skelettszintigraphie und die Positronenemissionstomographie mit Acetat- oder Cholintracern und diese ebenfalls nur bei entsprechend hohen PSA-Werten sinnvoll. Therapeutisch kommt nach primärer Radikaloperation und Verdacht auf einen lokalen Progress in erster Linie die Salvagebestrahlung zur Anwendung, nach primärer Radiatio wird allerdings vorwiegend die hormonelle Manipulation einer Salvageoperation oder alter“nativen lokaltherapeutischen Maßnahmen vorgezogen.

    Complex partial seizures (CPSs) can present with various semiologies, while mesial temporal lobe epilepsy (mTLE) is a well-recognized cause of CPS, neocortical temporal lobe epilepsy (nTLE) albeit being less common is increasingly recognized as separate disease entity. Differentiating the two remains a challenge for epileptologists as many symptoms overlap due to reciprocal connections between the neocortical and the mesial temporal regions. Various studies have attempted to correctly localize the seizure focus in nTLE as patients with this disorder may benefit from surgery. While earlier work predicted poor outcomes in this population, recent work challenges those ideas yielding good outcomes in part due to better localization using improved anatomical and functional techniques. This paper provides a comprehensive review of the diagnostic workup, particularly the application of recent advances in electroencephalography and functional brain imaging, in neocortical temporal lobe epilepsy.

    Vrionis, F D; Robertson, J H; Gardner, G; Heilman, C B

    1999-01-01

    Meningiomas involving the temporal bone may originate from arachnoid cell nests present within the temporal bone (intratemporal), but more frequently originate from arachnoid cell nests of the posterior or middle cranial fossa with secondary invasion of the TB (extratemporal). In this study, we retrospectively reviewed the charts of 13 patients with meningiomas involving the temporal bone who underwent surgery. Tumors of the posterior fossa with only temporal bone hyperostosis, but without invasion, were excluded. Patients presented primarily with otologic symptoms and signs. The tumors originated in the temporal bone (5/13), jugular foramen (4/13), petroclival region (2/13), the asterion (1/13) or the internal auditory meatus (1/13). All of the intratemporal meningiomas had the radiological appearance of en-plaque menigiomas. The tumor extended into the middle ear (11/13), eustachian tube (5/13), and/or the labyrinth (3/13). A gross total resection was achieved in 11 patients and a subtotal resection in 2 patients. The lower cranial nerves were infiltrated by tumor in 4 patients, and were sacrificed. At a mean follow-up of approximately 6 years, 12 patients are currently alive and doing well and 1 died from tumor progression. Six patients showed tumor recurrence and were reoperated on (5/6) or followed conservatively (1/6). Surgical treatment of temporal bone meningiomas is associated with high recurrence rate due to indiscreet tumor margins. Combined surgical approaches (temporal craniotomy and mastoidectomy) by neurosurgical and otological teams are recommended for meningiomas originating in the temporal bone.

  20. Temporal network epidemiology

    CERN Document Server

    Holme, Petter

    2017-01-01

    This book covers recent developments in epidemic process models and related data on temporally varying networks. It is widely recognized that contact networks are indispensable for describing, understanding, and intervening to stop the spread of infectious diseases in human and animal populations; “network epidemiology” is an umbrella term to describe this research field. More recently, contact networks have been recognized as being highly dynamic. This observation, also supported by an increasing amount of new data, has led to research on temporal networks, a rapidly growing area. Changes in network structure are often informed by epidemic (or other) dynamics, in which case they are referred to as adaptive networks. This volume gathers contributions by prominent authors working in temporal and adaptive network epidemiology, a field essential to understanding infectious diseases in real society.

    Full Text Available ABSTRACT The well-known phenomenological argument draws metaphysical conclusions about time, specifically about change through time and the resulting passage or flow of time, from our temporal experience. The argument begins with the phenomenological premise that there is a class of properties which underlies our experience of time and change through time, and its conclusion is that these properties are not merely experienced but exemplified. I argue that the phenomenological argument is best served by the adoption of a representational theory of perception. I then present a representational theory of temporal experience.

    2016-09-01

    Being able to give reasons for what the world is and how it works is one of the defining characteristics of modernity. Mathematical reason and empirical observation brought science and engineering to unprecedented success. However, modernity has reached a post-state where an instrumental view of technology needs revision with reasonable arguments and evidence, i.e. without falling back to superstition and mysticism. Instrumentally, technology bears the potential to ease and to harm. Easing and harming can't be controlled like the initial development of technology is a controlled exercise for a specific, mostly easing purpose. Therefore, a revised understanding of information technology is proposed based upon mathematical concepts and intuitions as developed in quantum mechanics. Quantum mechanics offers unequaled opportunities because it raises foundational questions in a precise form. Beyond instrumentalism it enables to raise the question of essences as that what remains through time what it is. The essence of information technology is acausality. The time of acausality is temporality. Temporality is not a concept or a category. It is not epistemological. As an existential and thus more comprehensive and fundamental than a concept or a category temporality is ontological; it does not simply have ontic properties. Rather it exhibits general essences. Datability, significance, spannedness and openness are general essences of equiprimordial time (temporality).

    Blair, Robert D G

    2012-01-01

    Epilepsy represents a multifaceted group of disorders divided into two broad categories, partial and generalized, based on the seizure onset zone. The identification of the neuroanatomic site of seizure onset depends on delineation of seizure semiology by a careful history together with video-EEG, and a variety of neuroimaging technologies such as MRI, fMRI, FDG-PET, MEG, or invasive intracranial EEG recording. Temporal lobe epilepsy (TLE) is the commonest form of focal epilepsy and represents almost 2/3 of cases of intractable epilepsy managed surgically. A history of febrile seizures (especially complex febrile seizures) is common in TLE and is frequently associated with mesial temporal sclerosis (the commonest form of TLE). Seizure auras occur in many TLE patients and often exhibit features that are relatively specific for TLE but few are of lateralizing value. Automatisms, however, often have lateralizing significance. Careful study of seizure semiology remains invaluable in addressing the search for the seizure onset zone.

As sementes de urucum, representadas por quatro acessos genéticos, e por três lotes, foram avaliadas pelos testes de germinação, primeira contagem da germinação, classificação do vigor das plântulas e emergência das plântulas (total e índice de velocidade. No teste de envelhecimento acelerado foram avaliados a temperatura, de 41 ºC, e os períodos, de 48; 72 e 96 horas, de exposição das sementes às umidades relativas de 100% (água e de 76% (solução saturada de NaCl. A solução saturada reduz a quantidade de água absorvida pelas sementes de urucum, expostas às condições do teste de envelhecimento acelerado, reduzindo a deterioração das sementes, favorecendo a uniformidade dos resultados e a redução da proliferação de fungos, comuns na germinação das sementes de urucum. O teste de envelhecimento acelerado, com água ou solução salina, por 72 horas ou 96 horas, é eficiente para classificar as sementes de urucum quanto à qualidade.

  6. Spontaneous lateral temporal encephalocele.

    Science.gov (United States)

    2013-01-01

    A spontaneous encephalocele is one that develops either because of embryological maldevelopment or from a poorly understood postnatal process that permits brain herniation to occur. We here report a rare case of lateral temporal encephalocele extending to the infratemporal fossa under the zygomatic arch. At birth, the infant was noted to have a large cystic mass in the right side of the face. After being operated on initially in another center in the newborn period, the patient was referred to our clinic with a diagnosis of temporal encephalocele. He was 6 months old at the time of admission. Computerized tomography scan and magnetic resonance imaging studies revealed a 8 × 9 cm fluid-filled, multiloculated cystic mass at the right infratemporal fossa. No intracranial pathology or connection is seen. The patient was operated on to reduce the distortion effect of the growing mass. The histopathological examination of the sac revealed well-differentiated mature glial tissue stained with glial fibrillary acid protein. This rare clinical presentation of encephaloceles should be taken into consideration during the evaluation of the lateral facial masses in the infancy period, and possible intracranial connection should be ruled out before surgery to avoid complications.

    Full Text Available Resumo Na perspectiva da Psicologia Social em diálogo com as teorizações de Michel Foucault e Giorgio Agamben, o objetivo deste artigo é problematizar de que maneira as drogas são constituídas como explicação para assassinatos de moradores de rua, construindo práticas e discursos relacionados ao governo da vida e da morte nas cidades. O material que apresentamos consiste em textos midiáticos e documentos públicos elaborados entre julho de 2010 e novembro de 2012 abordando tais assassinatos. Analisamos como o dispositivo das drogas formula uma ambiguidade e uma complexidade importantes para o governo dos moradores de rua a partir da construção de oposições: criminoso ou em situação de vulnerabilidade social. Procuramos contribuir criticamente com políticas públicas que visem os diversos modos de existir na cidade, pensar os espaços urbanos, os modos de governo e os processos de subjetivação, considerando a análise da ambiguidade e da complexidade produzidas em torno do dispositivo das drogas.

  13. Model Based Temporal Reasoning

    Systems that assess the real world must cope with evidence that is uncertain, ambiguous, and spread over time. Typically, the most important function of an assessment system is to identify when activities are occurring that are unusual or unanticipated. Model based temporal reasoning addresses both of these requirements. The differences among temporal reasoning schemes lies in the methods used to avoid computational intractability. If we had n pieces of data and we wanted to examine how they were related, the worst case would be where we had to examine every subset of these points to see if that subset satisfied the relations. This would be 2n, which is intractable. Models compress this; if several data points are all compatible with a model, then that model represents all those data points. Data points are then considered related if they lie within the same model or if they lie in models that are related. Models thus address the intractability problem. They also address the problem of determining unusual activities if the data do not agree with models that are indicated by earlier data then something out of the norm is taking place. The models can summarize what we know up to that time, so when they are not predicting correctly, either something unusual is happening or we need to revise our models. The model based reasoner developed at Advanced Decision Systems is thus both intuitive and powerful. It is currently being used on one operational system and several prototype systems. It has enough power to be used in domains spanning the spectrum from manufacturing engineering and project management to low-intensity conflict and strategic assessment.

  14. Multiple Temporalities, Layered Histories

    Full Text Available In Quotational Practices: Repeating the Future in Contemporary Art, Patrick Greaney asserts, “the past matters not only because of what actually happened but also because of the possibilities that were not realized and that still could be. Quotation evokes those possibilities. By repeating the past, artists and writers may be attempting to repeat that past’s unrealized futures.”[1]  In the information age, the Internet, for instance, provides us an expanded collection of visual information—quite literally available at our fingertips—summoning together aspects of the past and possibilities of the future into a boundless present. Sketchbook Revisions (2014–2015, a series of mixed-media paintings, represents my attempt to communicate the ways in which I experience my contemporary moment constructed from multiple temporalities excavated from my past. This body of work combines fragments of representational paintings created between 1995 and 2003 and nonrepresentational renderings produced between 2003 and 2014. Using traditional tracing paper and graphic color, I randomly select moments of my previous work to transfer and layer over selected areas of already-filled pages of a sketchbook I used from 2003 to 2004. These sketches depict objects I encountered in studio art classrooms and iconic architecture on the campus of McDaniel College, and often incorporate teaching notes. The final renditions of fragmented and layered histories enact the ways that we collectively experience multiple temporalities in the present. Quoting my various bodies of work, Sketchbook Revisions challenges both material and conceptual boundaries that determine fixed notions of artistic identity.

    This paper aims at analyzing the main operation and design of operationally robust controllers in order to damp the electromechanics oscillations type inter area. For this we used an intelligent control technique based on artificial neural networks, where a multilayer perceptron it was implemented. We used a symmetrical test system of four generators, ten bars and nine transmission lines to verify the performance of the power system stabilizers and power oscillation damping (POD) for the FACTS devices, unified power flow controller (UPFC), designed for neural networks. The results show the superiority in the operation and control of oscillations in power systems using UPFC equipped with the POD.

  16. [Temporal meaning of suffering].

    Science.gov (United States)

    Porée, J

    2015-09-01

    If we had to find a few simple words to express what a suffering human being experiences, no matter what ills are causing the suffering and no matter what circumstances underlie the ills themselves, we could unmistakably say that it is the experience of not being able to go on like this. Suffering can be described, in this same sense, as an alteration in temporality. However, describing suffering as such only makes sense if we already have a conception of normal temporality. Yet for this, philosophical tradition offers not one but four competing conceptions. In the present article, we begin by briefly presenting these different conceptions. We then show how each one sheds light, by way of contrast, on a phenomenon whose meaning thus appears to be essentially negative. But does this phenomenon have a negative meaning only? Doesn't it correspond as much to a transformation as an alteration of temporality? This is what we will strive to establish in the third part of the article by relating suffering to hope, in a paradoxical sense of the term. Of the four conceptions of time likely to shed a contrasting light on the upheavals that suffering introduces into our life experience, the one described by Aristotle in Physics is historically the first. In particular, the notion of succession originates therein. But this conception does not account for what makes time the unit of a past, a present, and a future. In Book XI of Confessions, St. Augustine situated this unit not in nature but in the human mind. Hence, his definition of time as a distension of the soul and the necessary division into physical time and psychic time it entails. Husserl's Lessons on the phenomenology of the consciousness of internal time lend credit to this division, but they illuminate only the internal constitution of the "present", which is at the heart of the psychological conception of time. In Being and Time, Heidegger breaks away from this long-standing tradition; in his view, physical time

  17. Temporal Representation in Semantic Graphs

    2007-08-07

    A wide range of knowledge discovery and analysis applications, ranging from business to biological, make use of semantic graphs when modeling relationships and concepts. Most of the semantic graphs used in these applications are assumed to be static pieces of information, meaning temporal evolution of concepts and relationships are not taken into account. Guided by the need for more advanced semantic graph queries involving temporal concepts, this paper surveys the existing work involving temporal representations in semantic graphs.

    Full Text Available Introduction. Intracranial extension of cholesteatoma is rare. This may occur de novo or recur some time later either contiguous with or separate to the site of the original cholesteatoma. Presentation of Case. A 63-year-old female presented to a tertiary referral hospital with a fluctuating level of consciousness, fever, headache, and right-sided otorrhoea, progressing over several days. Her past medical history included surgery for right ear cholesteatoma and drainage of intracranial abscess 23 years priorly. There had been no relevant symptoms in the interim until 6 weeks prior to this presentation. Imaging demonstrated a large right temporal lobe mass contiguous with the middle ear and mastoid cavity with features consistent with cholesteatoma. The patient underwent a combined transmastoid/middle fossa approach for removal of the cholesteatoma and repair of the tegmen dehiscence. The patient made an uneventful recovery and remains well over 12 months later. Conclusion. This case presentation details a large intracranial cholesteatoma which had extended through a tegmen tympani dehiscence from recurrent right ear cholesteatoma treated by modified radical mastoidectomy over two decades priorly. There was a completely asymptomatic progression of disease until several weeks prior to this presentation.

    Rigorous characterization of the performance and generalization ability of cyber defense systems is extremely difficult, making it hard to gauge uncertainty, and thus, confidence. This difficulty largely stems from a lack of labeled attack data that fully explores the potential adversarial space. Currently, performance of cyber defense systems is typically evaluated in a qualitative manner by manually inspecting the results of the system on live data and adjusting as needed. Additionally, machine learning has shown promise in deriving models that automatically learn indicators of compromise that are more robust than analyst-derived detectors. However, to generate these models, most algorithms require large amounts of labeled data (i.e., examples of attacks). Algorithms that do not require annotated data to derive models are similarly at a disadvantage, because labeled data is still necessary when evaluating performance. In this work, we explore the use of temporal generative models to learn cyber attack graph representations and automatically generate data for experimentation and evaluation. Training and evaluating cyber systems and machine learning models requires significant, annotated data, which is typically collected and labeled by hand for one-off experiments. Automatically generating such data helps derive/evaluate detection models and ensures reproducibility of results. Experimentally, we demonstrate the efficacy of generative sequence analysis techniques on learning the structure of attack graphs, based on a realistic example. These derived models can then be used to generate more data. Additionally, we provide a roadmap for future research efforts in this area.

O estudo foi abordado a partir da abordagem da Nova Economia Institucional. As instituições jurídicas são importantes componentes na formatação do sistema de contratação; a atuação dessas instituições tende a restringir algumas formas de contratação e incentivar outras. Verificou-se que as instituições jurídicas apresentavam grandes restrições quanto ao funcionamento e contratação das cooperativas de trabalhadores rurais, pois muitas delas apresentavam um caráter fraudulento, acarretando perda de diretos trabalhistas à mão-de-obra que prestava serviço nas propriedades rurais por meio das cooperativas. Além disso, as empresas que contratavam essas cooperativas estariam gerando elevados riscos potenciais de custos de transação adotando este sistema de contração de trabalhadores rurais.The purpose of this study is to analyze the agricultural seasonal labor contract system and mainly the rural labor cooperatives, from the legal system's point of view. Legal institutions are important components that affect the agricultural seasonal labor contract. Therefore, these institutions trend to restrict some contract frameworks and to provide incentive to other contracts. The work verified that rural labor cooperatives have high restrictions from legal institutions. The reason is the high incidence of corruption in this contract system. Thus, there is a potential increase in the transactions cost of the labor contract system.

    Traumatic injury to the temporal bone can lead to significant morbidity or mortality and knowledge of the pertinent anatomy, pathophysiology of injury, and appropriate management strategies is critical for successful recovery and rehabilitation of such injured patients. Most temporal bone fractures are caused by motor vehicle accidents. Temporal bone fractures are best classified as either otic capsule sparing or otic capsule disrupting-type fractures, as such classification correlates well with risk of concomitant functional complications. The most common complications of temporal bone fractures are facial nerve injury, cerebrospinal fluid (CSF) leak, and hearing loss. Assessment of facial nerve function as soon as possible following injury greatly facilitates clinical decision making. Use of prophylactic antibiotics in the setting of CSF leak is controversial; however, following critical analysis and interpretation of the existing classic and contemporary literature, we believe its use is absolutely warranted.

  5. Temporal bone trauma and imaging

    International Nuclear Information System (INIS)

    Turetschek, K.; Czerny, C.; Wunderbaldinger, P.; Steiner, E.

    1997-01-01

    Fractures of the temporal bone result from direct trauma to the temporal bone or occur as one component of a severe craniocerebral injury. Complications of temporal trauma are hemotympanon, facial nerve paralysis, conductive or sensorineur hearing loss, and leakage of cerebrospinal fluid. Erly recognition and an appropiate therapy may improve or prevent permanent deficits related to such complications. Only 20-30% of temporal bone fractures can be visualized by plain films. CT has displaced plain radiography in the investigation of the otological trauma because subtle bony details are best evaluated by CT which even can be reformatted in multiple projections, regardless of the original plane of scanning. Associated epidural, subdural, and intracerebral hemorrhagic lesions are better defined by MRI. (orig.) [de

  6. The grounding of temporal metaphors.

    2016-03-01

    Grounded cognition suggests that the processing of conceptual knowledge cued by language relies on the sensory-motor regions. Does temporal language similarly engage brain areas involved in time perception? Participants read sentences that describe the temporal extent of events with motion verbs (The hours crawled until the release of the news) and their static controls. Comparison conditions were fictive motion (The trail crawled until the end of the hills) and literal motion (The caterpillar crawled towards the top of the tree), along with their static controls. Several time sensitive locations, identified using a meta-analysis, showed activation specific to temporal metaphors, including in the left insula, right claustrum, and bilateral posterior superior temporal sulci. Fictive and literal motion contrasts did not show this difference. Fictive motion contrast showed activation in a conceptual motion sensitive area of the left posterior inferior temporal sulcus (ITS). These data suggest that language of time is at least partially grounded in experiential time. In addition, motion semantics has different consequences for events and objects: temporal events become animate, while static entities become motional. Copyright © 2016 Elsevier Ltd.

  7. Distributed Acoustic Sensing (DAS) Array near a Highway for Traffic Monitoring and Near-Surface Shear-Wave Velocity Profiles

    Monitoring traffic is important for many technical reasons. It allows for better design of future roads and assessment of the state of current roads. The number, size, weight, and speed of vehicles control deterioration rate. Also, real-time information supplies data to intelligent information systems to help control traffic. Recently there have been studies looking at monitoring traffic seismically as vibrations from traffic are not sensitive to weather and poor visibility. Furthermore, traffic noise can be used to image S-wave velocity distribution in the near surface by capturing and interpreting Rayleigh and Love waves (Nakata, 2016; Zeng et al. 2016). The capability of DAS for high spatial sampling (1 m), temporal sampling (up to 10 kHz), and distributed nature (tens of kilometers) allows for a closer look at the traffic as it passes and how the speed of the vehicle may change over the length of the array. The potential and difficulties of using DAS for these objectives were studied using two DAS arrays. One at Garner Valley in Southern California (a 700-meter array adjacent to CA Highway 74) and another in Brady Hot Springs, Nevada (an 8700-meter array adjacent to Interstate 80). These studies experimentally evaluated the use of DAS data for monitoring traffic and assessing the use of traffic vibration as non-localized sources for seismic imaging. DAS arrays should also be resilient to issues with lighting conditions that are problematic for video monitoring and it may be sensitive to the weight of a vehicle. This study along a major interstate provides a basis for examining DAS' potential and limitations as a key component of intelligent highway systems.

    The term `inflammation of the middle ear` covers a couple of deseases which range from the acute otitis media to the middle ear cholesteatoma. However, a clear characterization of a certain pathology is essential for any further treatment. Therefore this article presents a short overview about the different types of infections and their clinical manifestation. The tumors of the temporal bone show a great variety in their incidence. Even if tumors like the acoustic neurinoma or the paraganglioma are compareable common, the chondroblastoma of the temporal bone is absolutely rare. In spite of these differences the individual temporal bone neoplasias are shortly mentioned herein. (orig.) [Deutsch] Der Begriff Mittelohrentzuendung umfasst ein weites Spektrum von Krankheiten welches von der akuten Mittelohrentzuendung bis hin zum Cholesteatom reicht. Es soll in diesem Artikel eine kurze Uebersicht ueber die verschiedenen Entzuendungen gegeben werden, wobei vor allem auf eine klare Begriffsdefinition der einzelnen Entzuendungsformen und deren klinisches Erscheinungsbild geachtet wurde. Bei den Tumoren des Schlaefenbeins ist ein grosser Unterschied in der Inzidenz der einzelnen Tumoren gegeben. Waehrend Neubildungen wie das Akustikusneurinom oder das Paragangliom vergleichsweise haeufig im klinischen Alltag zu sehen sind, stellen Veraenderungen wie das Chondroblastom eine Raritaet dar. Trotz dieses Unterschieds im Vorkommen der verschiedenen Tumoren, wurde versucht, einen kurzen Gesamtueberblick ueber die Tumore des Mittel- und Innenohres zu geben. (orig.)

    To report the increasing frequency with which temporal anteroinferior encephalocele is a cause of adult temporal lobe epilepsy, to illustrate the clinical and imaging characteristics of this condition, and to report its surgical treatment in a series of 23 adult patients. Epilepsy patients diagnosed with temporal anteroinferior encephalocele from January 2006 to December 2013 in a national epilepsy reference center were included in this noninterventional study. Twenty-three epilepsy patients (14 female, mean age 43.8 years) were diagnosed with temporal anteroinferior encephalocele in our institute. Thirteen patients had ≥2 encephaloceles; 7 cases presented bilaterally. The estimated frequency of this condition was 0.3% among MRI examinations performed due to newly diagnosed epilepsy (n = 6) and 1.9% among drug-resistant patients referred to our center (n = 17). Nine patients with local encephalocele disconnection (n = 4) or anterior temporal lobectomy and amygdalohippocampectomy (n = 5) have become seizure-free (Engel 1) for a mean 2.8 years (range 3 months-6.2 years) of follow-up. Three patients with local encephalocele disconnection were almost seizure-free or exhibited worthwhile improvement. Histologically, all 12 surgical patients had gliosis at the base of the encephalocele; some had cortical laminar disorganization (n = 5) or mild hippocampal degeneration (n = 1). The possibility of a temporal encephalocele should be considered when interpreting MRI examinations of patients with medically intractable focal epilepsy. These patients can significantly benefit from unitemporal epilepsy surgery, even in cases with bilateral encephaloceles. © 2015 American Academy of Neurology.

  15. Temporal coordination between performing musicians.

    Loehr, Janeen D; Palmer, Caroline

    2011-11-01

    Many common behaviours require people to coordinate the timing of their actions with the timing of others' actions. We examined whether representations of musicians' actions are activated in coperformers with whom they must coordinate their actions in time and whether coperformers simulate each other's actions using their own motor systems during temporal coordination. Pianists performed right-hand melodies along with simple or complex left-hand accompaniments produced by themselves or by another pianist. Individual performers' preferred performance rates were measured in solo performance of the right-hand melody. The complexity of the left-hand accompaniment influenced the temporal grouping structure of the right-hand melody in the same way when it was performed by the self or by the duet partner, providing some support for the action corepresentation hypothesis. In contrast, accompaniment complexity had little influence on temporal coordination measures (asynchronies and cross-correlations between parts). Temporal coordination measures were influenced by a priori similarities between partners' preferred rates; partners who had similar preferred rates in solo performance were better synchronized and showed mutual adaptation to each other's timing during duet performances. These findings extend previous findings of action corepresentation and action simulation to a task that requires precise temporal coordination of independent yet simultaneous actions.

    DAS is a widely adopted protocol for providing syntactic interoperability among biological databases. The popularity of DAS is due to a simplified and elegant mechanism for data exchange that consists of sources exposing their RESTful interfaces for data access. As a growing number of DAS services are available for molecular biology resources, there is an incentive to explore this protocol in order to advance data discovery and integration among these resources. We developed DASMiner, a Matlab toolkit for querying DAS data sources that enables creation of integrated biological models using the information available in DAS-compliant repositories. DASMiner is composed by a browser application and an API that work together to facilitate gathering of data from different DAS sources, which can be used for creating enriched datasets from multiple sources. The browser is used to formulate queries and navigate data contained in DAS sources. Users can execute queries against these sources in an intuitive fashion, without the need of knowing the specific DAS syntax for the particular source. Using the source's metadata provided by the DAS Registry, the browser's layout adapts to expose only the set of commands and coordinate systems supported by the specific source. For this reason, the browser can interrogate any DAS source, independently of the type of data being served. The API component of DASMiner may be used for programmatic access of DAS sources by programs in Matlab. Once the desired data is found during navigation, the query is exported in the format of an API call to be used within any Matlab application. We illustrate the use of DASMiner by creating integrative models of histone modification maps and protein-protein interaction networks. These enriched datasets were built by retrieving and integrating distributed genomic and proteomic DAS sources using the API.

    Full Text Available É difícil encontrar ossos temporais humanos para o ensino de cirurgia otológica. Ossos temporais de ovelhas podem representar uma possível alternativa. MATERIAIS E MÉTODOS: Os ossos temporais de ovelhas foram dissecados em um programa convencional de dissecação de osso temporal no laboratório. Incluímos mastoidectomia, abordagens endaurais, mas também analisamos a aparência externa, o meato acústico externo e o hipotímpano. Algumas etapas são diferentes das preparações de ossos humanos. Os resultados morfométricos foram comparados à anatomia conhecida de humanos para verificar se o osso temporal de ovelhas seria utilizável para o ensino de cirurgia otológica. RESULTADOS: O osso temporal de ovelhas parece menor do que o humano. Encontramos uma área bolhosa se estendendo ao hipotímpano abaixo do meato acústico externo. A membrana timpânica é muito semelhante à humana. O meato acústico externo é menor e mais curto. A cadeia ossicular exibe analogias para com a humana. DISCUSSÃO: Esse estudo mostra que especificamente o ouvido médio, a membrana timpânica e o conduto auditivo externo são morfologicamente semelhantes às suas contrapartidas encontradas nos ossos temporais humanos. A ovelha parece ser um modelo viável para o ensino da anatomia do ouvido. A menor escala de algumas estruturas, especialmente dos componentes externos do osso temporal representa uma desvantagem.

    2012-01-01

    The temporal lobe is a common focus for epilepsy. Temporal lobe epilepsy in infants and children differs from the relatively homogeneous syndrome seen in adults in several important clinical and pathological ways. Seizure semiology varies by age, and the ictal EEG pattern may be less clear cut than what is seen in adults. Additionally, the occurrence of intractable seizures in the developing brain may impact neurocognitive function remote from the temporal area. While many children will respond favorably to medical therapy, those with focal imaging abnormalities including cortical dysplasia, hippocampal sclerosis, or low-grade tumors are likely to be intractable. Expedient workup and surgical intervention in these medically intractable cases are needed to maximize long-term developmental outcome. PMID:22957247

    2017-10-01

    Several characteristics of emotions are that they: first, evolve dynamically over time, second, extend beyond the individual to incorporate multiple people, and third, function as a system. In other words, emotions can be seen as temporal interpersonal systems. This review summarizes current models for temporal interpersonal emotion systems (TIES), evidence they matter beyond levels of emotional responding, their connections with relationship quality and interpersonal regulation, and some of the challenges for studying them. Important directions for future research include distinguishing between different patterns of interpersonal emotional dynamics and extending theory and experimental work to uncover mechanisms for altering harmful TIES and promoting beneficial ones.

    Dalsgård, Anne Line; Frederiksen, Martin Demant; Højlund, Susanne

    As we experience and manipulate time—be it as boredom or impatience—it becomes an object: something materialized and social, something that affects perception, or something that may motivate reconsideration and change. The editors and contributors to this important new book, Ethnographies of Youth...... and Temporality, have provided a diverse collection of ethnographic studies and theoretical explorations of youth experiencing time in a variety of contemporary socio-cultural settings. The essays in this volume focus on time as an external and often troubling factor in young people’s lives, and show how...... of Youth and Temporality use youth as a prism to understand time and its subjective experience....

    Full Text Available Die Idee, dass vor allem monetäre Anreize das Verhalten von Wirtschaftsakteuren in gewünschte Richtungen lenken und sogar dabei helfen können, durch Leistungssteigerung zusätzliche Wohlfahrtseffekte zu generieren, spielt in der politischen Ökonomie seit ihren Anfängen eine zentrale Rolle. Es spricht sogar einiges dafür, dass dieser Gedanke das verbindende Glied der Ökonomik als Gesellschaftstheorie im Gegensatz zu anderen gesellschaftstheoretischen Entwürfen ausmacht. Dennoch halte ich dieses Anreizargument aus normativer Perspektive für unterentwickelt, wie ich in Auseinandersetzung mit der Ökonomischen Ethik bzw. Ordnungsethik nach Karl Homann und der Integrativen Wirtschaftsethik zeigen möchte. Weder gelingt es der Ordnungsethik nach Karl Homann, die Bedeutung von Anreizstrukturen hinreichend zu begründen, obwohl sie in Ansätzen wichtige Argumente formuliert. Noch gelingt es der Integrativen Wirtschaftsethik, die zentrale Rolle von Anreizstrukturen für die normative Theoriebildung überzeugend zurückzuweisen. Mir geht es nicht darum, den einen oder anderen wirtschaftsethischen Ansatz grundsätzlich zurückzuweisen, sondern vielmehr, auf Lücken in der Argumentation und sich daraus ergebende Forschungsfragen hinzuweisen. Vor diesem Hintergrund könnte es helfen, einen verwandten Diskurs aus der gegenwärtigen Gerechtigkeitstheorie in die Überlegungen mit einzubeziehen. Denn die grundlegende Idee der ökonomischen Gesellschaftstheorie einer Wohlfahrtssteigerung durch die gezielte Manipulation von Anreizstrukturen hat auch in der gegenwärtigen Gerechtigkeitstheorie ihre Wirkung entfaltet. In seiner Theorie der Gerechtigkeit hat John Rawls argumentiert, dass selbst Egalitaristen bestimmte Einkommensunterschiede zulassen müssen, wenn dadurch für Leistungsträgerinnen solche Anreize gesetzt werden, die gleichzeitig auch den Schlechtestgestellten zum Vorteil gereichen. Diese Argumentation ist von Gerald Cohen einer harschen

    For the study of information propagation, one fundamental problem is uncovering universal laws governing the dynamics of information propagation. This problem, from the microscopic perspective, is formulated as estimating the propagation probability that a piece of information propagates from one individual to another. Such a propagation probability generally depends on two major classes of factors: the intrinsic attractiveness of information and the interactions between individuals. Despite the fact that the temporal effect of attractiveness is widely studied, temporal laws underlying individual interactions remain unclear, causing inaccurate prediction of information propagation on evolving social networks. In this report, we empirically study the dynamics of information propagation, using the dataset from a population-scale social media website. We discover a temporal scaling in information propagation: the probability a message propagates between two individuals decays with the length of time latency since their latest interaction, obeying a power-law rule. Leveraging the scaling law, we further propose a temporal model to estimate future propagation probabilities between individuals, reducing the error rate of information propagation prediction from 6.7% to 2.6% and improving viral marketing with 9.7% incremental customers.

    We report a case of temporal bone necrosis that emerged after radiotherapy for epipharyngeal carcinoma performed 13 years ago. The patient was a 51-year-old male. His major complaint was left facial swelling. The patient underwent chemotherapy and radiotherapy (Co 60, 6120 rad), as the treatment of that period, for epipharyngeal carcinoma from September 30, 1986 to January 31, 1987. He also underwent lobectomy of the left temporal lobe in brain surgery for left temporal lobe necrosis in August, 1989. After that operation, we saw constriction in his left external acoustic meatus and continued the follow-up. On October 22, 1999 he felt a left facial swelling. We found skin defects and ulcer formation in the front part of his left ear. Although we administered an antiseptic and antibiotic to the diseased area, his condition did not improve. He was hospitalized for the purpose of undergoing medical treatment on January 6, 2000. We found extensive skin necrosis and defects in his left auricular area. The corrupted temporal bone reached the zygomatic, the bone department external acoustic meatus and the mastoid process was exposing. We performed debridement of the diseased area on January 19, 2000. On February 23, we performed reconstruction by left trapezius muscle flap after debridement once again. One year after the operation, the flap was completely incorporated. (author)

  16. Temporal Coding of Volumetric Imagery

    Science.gov (United States)

    Llull, Patrick Ryan

    'Image volumes' refer to realizations of images in other dimensions such as time, spectrum, and focus. Recent advances in scientific, medical, and consumer applications demand improvements in image volume capture. Though image volume acquisition continues to advance, it maintains the same sampling mechanisms that have been used for decades; every voxel must be scanned and is presumed independent of its neighbors. Under these conditions, improving performance comes at the cost of increased system complexity, data rates, and power consumption. This dissertation explores systems and methods capable of efficiently improving sensitivity and performance for image volume cameras, and specifically proposes several sampling strategies that utilize temporal coding to improve imaging system performance and enhance our awareness for a variety of dynamic applications. Video cameras and camcorders sample the video volume (x,y,t) at fixed intervals to gain understanding of the volume's temporal evolution. Conventionally, one must reduce the spatial resolution to increase the framerate of such cameras. Using temporal coding via physical translation of an optical element known as a coded aperture, the compressive temporal imaging (CACTI) camera emonstrates a method which which to embed the temporal dimension of the video volume into spatial (x,y) measurements, thereby greatly improving temporal resolution with minimal loss of spatial resolution. This technique, which is among a family of compressive sampling strategies developed at Duke University, temporally codes the exposure readout functions at the pixel level. Since video cameras nominally integrate the remaining image volume dimensions (e.g. spectrum and focus) at capture time, spectral (x,y,t,lambda) and focal (x,y,t,z) image volumes are traditionally captured via sequential changes to the spectral and focal state of the system, respectively. The CACTI camera's ability to embed video volumes into images leads to exploration

TB showed a higher incidence among individuals with less schooling (< 8 years, while PCP and KS had higher incidence rates among those with 8 or more years of schooling, despite similar downward trends. Access to antiretroviral therapy and OI prophylaxis may partially explain these results. However, data reliability, delay in reporting, OI incidence after AIDS, and reporting and diagnostic criteria are factors that also need to be carefully assessed.

    Full Text Available On the route to a spatio-temporal geoscience information system, an appropriate data model for geo-objects in space and time has been developed. In this model, geo-objects are represented as sequences of geometries and properties with continuous evolution in each time interval. Because geomodeling software systems usually model objects at specific time instances, we want to interpolate the geometry and properties from two models of an object with only geometrical constraints (no physical or mechanical constraints. This process is called spatio-temporal data construction or morphological interpolation of intermediate geometries. This paper is strictly related to shape morphing, shape deformation, cross-parameterization and compatible remeshing and is only concerned with geological surfaces. In this study, two main sub-solutions construct compatible meshes and find trajectories in which vertices of the mesh evolve. This research aims to find an algorithm to construct spatio-temporal data with some constraints from the geosciences, such as cutting surfaces by faulting or fracturing phenomena and evolving boundaries attached to other surfaces. Another goal of this research is the implementation of the algorithm in a software product, namely a gOcad plug-in. The four main procedures of the algorithm are cutting the surfaces, setting up constraints, partitioning and calculating the parameterizations and trajectories. The software has been tested to construct data for a salt dome and other surfaces in regard to the geological processes of faulting, deposition and erosion. The result of this research is an algorithm and software for the construction of spatio-temporal data.

  6. The Machinic Temporality of Metadata

    Directory of Open Access Journals (Sweden)

    Claudio Celis

    2015-03-01

    Full Text Available In 1990 Deleuze introduced the hypothesis that disciplinary societies are gradually being replaced by a new logic of power: control. Accordingly, Matteo Pasquinelli has recently argued that we are moving towards societies of metadata, which correspond to a new stage of what Deleuze called control societies. Societies of metadata are characterised for the central role that meta-information acquires both as a source of surplus value and as an apparatus of social control. The aim of this article is to develop Pasquinelli’s thesis by examining the temporal scope of these emerging societies of metadata. In particular, this article employs Guattari’s distinction between human and machinic times. Through these two concepts, this article attempts to show how societies of metadata combine the two poles of capitalist power formations as identified by Deleuze and Guattari, i.e. social subjection and machinic enslavement. It begins by presenting the notion of metadata in order to identify some of the defining traits of contemporary capitalism. It then examines Berardi’s account of the temporality of the attention economy from the perspective of the asymmetric relation between cyber-time and human time. The third section challenges Berardi’s definition of the temporality of the attention economy by using Guattari’s notions of human and machinic times. Parts four and five fall back upon Deleuze and Guattari’s notions of machinic surplus labour and machinic enslavement, respectively. The concluding section tries to show that machinic and human times constitute two poles of contemporary power formations that articulate the temporal dimension of societies of metadata.

    A novel conceptual framework for theoretical psychology is presented and illustrated for the example of bistable perception. A basic formal feature of this framework is the non-commutativity of operations acting on mental states. A corresponding model for the bistable perception of ambiguous stimuli, the Necker-Zeno model, is sketched and some empirical evidence for it so far is described. It is discussed how a temporal nonlocality of mental states, predicted by the model, can be understood and tested.

    In many situations, imagers are required to have higher imaging speed, such as gunpowder blasting analysis and observing high-speed biology phenomena. However, measuring high-speed video is a challenge to camera design, especially, in infrared spectrum. In this paper, we reconstruct a high-frame-rate video from compressive video measurements using temporal compressive imaging (TCI) with a temporal compression ratio T=8. This means that, 8 unique high-speed temporal frames will be obtained from a single compressive frame using a reconstruction algorithm. Equivalently, the video frame rates is increased by 8 times. Two methods, two-step iterative shrinkage/threshold (TwIST) algorithm and the Gaussian mixture model (GMM) method, are used for reconstruction. To reduce reconstruction time and memory usage, each frame of size 256×256 is divided into patches of size 8×8. The influence of different coded mask to reconstruction is discussed. The reconstruction qualities using TwIST and GMM are also compared.

    Wolkovich, E M; Cook, B I; McLauchlan, K K; Davies, T J

    2014-11-01

    Two fundamental axes - space and time - shape ecological systems. Over the last 30 years spatial ecology has developed as an integrative, multidisciplinary science that has improved our understanding of the ecological consequences of habitat fragmentation and loss. We argue that accelerating climate change - the effective manipulation of time by humans - has generated a current need to build an equivalent framework for temporal ecology. Climate change has at once pressed ecologists to understand and predict ecological dynamics in non-stationary environments, while also challenged fundamental assumptions of many concepts, models and approaches. However, similarities between space and time, especially related issues of scaling, provide an outline for improving ecological models and forecasting of temporal dynamics, while the unique attributes of time, particularly its emphasis on events and its singular direction, highlight where new approaches are needed. We emphasise how a renewed, interdisciplinary focus on time would coalesce related concepts, help develop new theories and methods and guide further data collection. The next challenge will be to unite predictive frameworks from spatial and temporal ecology to build robust forecasts of when and where environmental change will pose the largest threats to species and ecosystems, as well as identifying the best opportunities for conservation. © 2014 John Wiley & Sons Ltd/CNRS.

    Temporal lobe epilepsy is diagnosed by clinical symptoms and signs and by localization of an epileptogenic focus. A brain SPECT study of two patients with temporal lobe epilepsy, using 99m Tc-HMPAO, was used to demonstrate a perfusion abnormality in the temporal lobe, while brain CT and MRI were non-contributory. The electroencephalogram, though abnormal, did not localize the diseased area. The potential role of the SPECT study in diagnosis and localization of temporal lobe epilepsy is discussed. (orig.)

    Full Text Available Constructing catalogue of temporal situations The paper is aiming to create a common basis for description, comparing, and analysis natural languages. As a subject of comparison we have chosen temporal structures of some languages. For such a choice there exists a perfect tool, describing basic temporal phenomena, namely an ordering of states and events in time, certainty and uncertainty, independency of histories of separate objects, necessity and possibility. This tool is supported by the Petri nets formalism, which seems to be well suited for expressing the above mentioned phenomena. Petri nets are built form three primitive notions: of states, of events that begin or end the states, and so-called flow relation indicating succession of states and events. This simple constituents give rise to many possibilities of representing temporal phenomena; it turns out that such representations are sufficient for many (clearly, not necessarily all temporal situations appearing in natural languages. In description formalisms used till now there is no possibility of expressing such reality phenomena as temporal dependencies in compound statement, or combination of temporality and modality. Moreover, using these formalisms one cannot distinguish between two different sources of uncertainty of the speaker while describing the reality: one, due to the lack of knowledge of the speaker what is going on in outside world, the second, due to objective impossibility of foreseen ways in which some conflict situations will be (or already have been resolved. Petri net formalism seems to be perfectly suited for such differentiations. There are two main description principles that encompassed this paper. First, that assigns meaning to names of grammatical structures in different languages may lead to misunderstanding. Two grammatical structures with apparently close names may describe different reality. Additionally, some grammatical terms used in one language may be

    The Data Access System (DAS) is a and data management software system, providing a reusable solution for the storage of data acquired both from telescopes and auxiliary data sources during the instrument development phases and operations. It is part of the Customizable Instrument WorkStation system (CIWS-FW), a framework for the storage, processing and quick-look at the data acquired from scientific instruments. The DAS provides a data access layer mainly targeted to software applications: quick-look displays, pre-processing pipelines and scientific workflows. It is logically organized in three main components: an intuitive and compact Data Definition Language (DAS DDL) in XML format, aimed for user-defined data types; an Application Programming Interface (DAS API), automatically adding classes and methods supporting the DDL data types, and providing an object-oriented query language; a data management component, which maps the metadata of the DDL data types in a relational Data Base Management System (DBMS), and stores the data in a shared (network) file system. With the DAS DDL, developers define the data model for a particular project, specifying for each data type the metadata attributes, the data format and layout (if applicable), and named references to related or aggregated data types. Together with the DDL user-defined data types, the DAS API acts as the only interface to store, query and retrieve the metadata and data in the DAS system, providing both an abstract interface and a data model specific one in C, C++ and Python. The mapping of metadata in the back-end database is automatic and supports several relational DBMSs, including MySQL, Oracle and PostgreSQL.

    2013-12-01

    Temporal information in clinical narratives plays an important role in patients' diagnosis, treatment and prognosis. In order to represent narrative information accurately, medical natural language processing (MLP) systems need to correctly identify and interpret temporal information. To promote research in this area, the Informatics for Integrating Biology and the Bedside (i2b2) project developed a temporally annotated corpus of clinical narratives. This corpus contains 310 de-identified discharge summaries, with annotations of clinical events, temporal expressions and temporal relations. This paper describes the process followed for the development of this corpus and discusses annotation guideline development, annotation methodology, and corpus quality. Copyright © 2013 Elsevier Inc.

    DAS-77 is a traditional herbal preparation composed of the young callous bark of mango (Mangifera indica Linn., Anacardiaceae) and the dried root of pawpaw (Carica papaya Linn., Caricaceae). This phytomedicine is claimed to have beneficial effects in the treatment of gastrointestinal disorders, including diarrhoea. To investigate the antidiarrhoeal effect of DAS-77 using standard pharmacological models. Normal and castor oil-induced intestinal transit, and castor oil-induced diarrhoea tests wore carried out in mice while intestinal fluid accumulation and gastric emptying tests were carried out in rats. Acute toxicity test and preliminary phytochemical analysis were also conducted. The results obtained in this study revealed that DAS-77 had no significant inhibitory effect on normal intestinal transit, castor oil-induced diarrhoea, intestinal fluid accumulation and gastric emptying. However, the inhibitory effect of DAS-77 was significant (psafety of the preparation. The i.p. LD50 was estimated to be 1122 mg/kg. The remedy was found to contain saponins, tannins, phenols and alkaloids. Findings in this study suggest that DAS-77 possesses antidiarrhoeal activity due to the inhibition of intestinal motility possibly mediated by muscarinic and alpha adrenergic receptors.

    1975-01-01

    A digital data acquisition system (DAS) based on a minicomputer is described which registers the failure sequences in various equipment areas of the CERN synchrocyclotron (henceforward referred to as the SC). The avalanches of failure signals which occur from time to time are tapped from the alarm/security systems, time-resolved to 10 msec and recorded on a printer in order to aid SC failure diagnosis. The mechanisms of the DAS and its relation to the SC equipment are explained in some detail. All programs were constructed at assembler language level for speed and for ease of on-line program maintenance. The alarm sequences recorded have been of considerable help during the running in of the new radiofrequency system. Now that the new SC is operational, the DAS furnishes useful data from several equipment areas to the operators and engineers.

    Lateral temporal encephalocele is an extremely rare clinical condition, with only 18 cases presented in the literature to date. No review articles have examined lateral temporal encephalocele in depth. We therefore reviewed past cases of lateral encephalocele to clarify the clinical characteristics of this extremely rare deformity. We also present a case of lateral encephalocele with arachnoid cyst which has never been reported in past reports. We identified 8 reports describing 18 cases of lateral temporal encephalocele. We therefore reviewed 19 cases of lateral temporal encephalocele, including our own experience, and discussed the clinical characteristics of this pathology. All the cases with lateral temporal encephalocele were detected at birth except for an occult case. The majority occurred at the pterion, and occurrence at the asterion appears much rarer. Due to the preference for the pterion, the ipsilateral orbital wall was also distorted in some cases. Lateral temporal encephalocele seems to have fewer associated malformations: only 3 cases of lateral temporal encephalocele had associated malformations, including our case which was associated with intracranial arachnoid cyst. The only case of lateral temporal encephalocele to have shown hydrocephalus was our own case. Patients with this deformity have relatively good prognoses: only 3 of the 19 cases showed delayed psychomotor development during follow-up. Provision of adequate treatment is likely to achieve a good prognosis in patients with lateral temporal encephalocele, so we should keep in mind this deformity when encountering pediatric patients with mass lesions on the temporal cranium.

  17. Auditory evoked fields elicited by spectral, temporal, and spectral-temporal changes in human cerebral cortex

    2012-05-01

    Full Text Available Natural sounds contain complex spectral components, which are temporally modulated as time-varying signals. Recent studies have suggested that the auditory system encodes spectral and temporal sound information differently. However, it remains unresolved how the human brain processes sounds containing both spectral and temporal changes. In the present study, we investigated human auditory evoked responses elicited by spectral, temporal, and spectral-temporal sound changes by means of magnetoencephalography (MEG. The auditory evoked responses elicited by the spectral-temporal change were very similar to those elicited by the spectral change, but those elicited by the temporal change were delayed by 30 – 50 ms and differed from the others in morphology. The results suggest that human brain responses corresponding to spectral sound changes precede those corresponding to temporal sound changes, even when the spectral and temporal changes occur simultaneously.

    Human visual temporal sensitivity is examined. The stimuli used to measure temporal sensitivity are described and the linear systems theory is reviewed in terms of temporal sensitivity. A working model which represents temporal sensitivity is proposed. The visibility of a number of temporal wave forms, sinusoids, rectangular pulses, and pulse pairs, is analyzed. The relation between spatial and temporal effects is studied. Temporal variations induced by image motion and the effects of light adaptation on temporal sensitivity are considered.

  1. A Temporal Map of Coaching

    2017-08-01

    Full Text Available Economic pressures on companies, technological developments, and less stable career paths pose potential threats to the well-being of employees (e.g., stress, burn-out and require constant adaptation. In the light of these challenges, it is not surprising that employees often seek the support of a coach. The role of a coach is to foster change by facilitating a coachees’ movement through a self-regulatory cycle with the ultimate aim of stimulating sustained well-being and functioning. While meta-analytic research indicates that coaching interventions can be effectively applied to assist employees in dealing with change, the current literature on coaching lacks solid theoretical frameworks that are needed to build a cumulative knowledge-base and to inspire evidence-based practice. In this conceptual analysis, we examine the coaching process through a temporal lens. By doing so, we provide an integrated theoretical framework: a temporal map of coaching. In this framework, we link seminal concepts in psychology to the coaching process, and describe which competencies of coachees are crucial in the different stages of change that coaching aims to bring about. During the preparatory contemplation stage, targeting coachees’ awareness by enhancing their mindfulness and environmental receptiveness is important. During the contemplation stage, coachees’ willingness and perceived ability to change are central competencies. We propose that coaches should therefore foster intrinsic goal orientation and self-efficacy during this stage. During the planning stage, coaches should focus on goal-setting and implementation intentions. Finally, during the maintenance/termination stage, stimulating coachees’ reflection is especially important in order to help them to integrate their learning experiences. The framework delineated in this paper contributes to the understanding of coaching as a tool to assist employees in dealing with the challenges of an

  2. Motor activity improves temporal expectancy.

    Directory of Open Access Journals (Sweden)

    Lilian Fautrelle

    Full Text Available Certain brain areas involved in interval timing are also important in motor activity. This raises the possibility that motor activity might influence interval timing. To test this hypothesis, we assessed interval timing in healthy adults following different types of training. The pre- and post-training tasks consisted of a button press in response to the presentation of a rhythmic visual stimulus. Alterations in temporal expectancy were evaluated by measuring response times. Training consisted of responding to the visual presentation of regularly appearing stimuli by either: (1 pointing with a whole-body movement, (2 pointing only with the arm, (3 imagining pointing with a whole-body movement, (4 simply watching the stimulus presentation, (5 pointing with a whole-body movement in response to a target that appeared at irregular intervals (6 reading a newspaper. Participants performing a motor activity in response to the regular target showed significant improvements in judgment times compared to individuals with no associated motor activity. Individuals who only imagined pointing with a whole-body movement also showed significant improvements. No improvements were observed in the group that trained with a motor response to an irregular stimulus, hence eliminating the explanation that the improved temporal expectations of the other motor training groups was purely due to an improved motor capacity to press the response button. All groups performed a secondary task equally well, hence indicating that our results could not simply be attributed to differences in attention between the groups. Our results show that motor activity, even when it does not play a causal or corrective role, can lead to improved interval timing judgments.

  3. Memory for temporally dynamic scenes.

    Ferguson, Ryan; Homa, Donald; Ellis, Derek

    2017-07-01

    Recognition memory was investigated for individual frames extracted from temporally continuous, visually rich film segments of 5-15 min. Participants viewed a short clip from a film in either a coherent or a jumbled order, followed by a recognition test of studied frames. Foils came either from an earlier or a later part of the film (Experiment 1) or from deleted segments selected from random cuts of varying duration (0.5 to 30 s) within the film itself (Experiment 2). When the foils came from an earlier or later part of the film (Experiment 1), recognition was excellent, with the hit rate far exceeding the false-alarm rate (.78 vs. 18). In Experiment 2, recognition was far worse, with the hit rate (.76) exceeding the false-alarm rate only for foils drawn from the longest cuts (15 and 30 s) and matching the false-alarm rate for the 5 s segments. When the foils were drawn from the briefest cuts (0.5 and 1.0 s), the false-alarm rate exceeded the hit rate. Unexpectedly, jumbling had no effect on recognition in either experiment. These results are consistent with the view that memory for complex visually temporal events is excellent, with the integrity unperturbed by disruption of the global structure of the visual stream. Disruption of memory was observed only when foils were drawn from embedded segments of duration less than 5 s, an outcome consistent with the view that memory at these shortest durations are consolidated with expectations drawn from the previous stream.

  4. SST: Single-Stream Temporal Action Proposals

    KAUST Repository

    Buch, Shyamal

    2017-11-09

    Our paper presents a new approach for temporal detection of human actions in long, untrimmed video sequences. We introduce Single-Stream Temporal Action Proposals (SST), a new effective and efficient deep architecture for the generation of temporal action proposals. Our network can run continuously in a single stream over very long input video sequences, without the need to divide input into short overlapping clips or temporal windows for batch processing. We demonstrate empirically that our model outperforms the state-of-the-art on the task of temporal action proposal generation, while achieving some of the fastest processing speeds in the literature. Finally, we demonstrate that using SST proposals in conjunction with existing action classifiers results in improved state-of-the-art temporal action detection performance.

    2010-04-15

    We experimentally demonstrate, for the first time to our knowledge, an ultrafast photonic high-order (second-order) complex-field temporal integrator. The demonstrated device uses a single apodized uniform-period fiber Bragg grating (FBG), and it is based on a general FBG design approach for implementing optimized arbitrary-order photonic passive temporal integrators. Using this same design approach, we also fabricate and test a first-order passive temporal integrator offering an energetic-efficiency improvement of more than 1 order of magnitude as compared with previously reported passive first-order temporal integrators. Accurate and efficient first- and second-order temporal integrations of ultrafast complex-field optical signals (with temporal features as fast as approximately 2.5ps) are successfully demonstrated using the fabricated FBG devices.

    In our previous in vivo study 67 Ga DFO-DAS-Fibrinogen was assessed for its usefulness as a radiopharmaceutical for the detection of thrombin in experimental animals (Report 1). The present study was undertaken to appraise the diagnostic value of 67 Ga DFO-DAS-Fibrinogen in human disease, especially in relation to blood coagulability as well as to thrombolytic drug regimen being given, in an effort to investigate its clinical applicability. Involved in this study were 48 patients with thrombosis proven by X-ray CT and other examinations. Of these 48, 42 had arterial thrombosis (20 with aortic aneurysm including the dissecting form, 11 in postoperative condition following vascular surgery with a prosthesis, 9 with intracardiac thrombosis accompanying heart disease, and 1 each with occlusive arteriosclerosis and cerebral infarction) and 6 had venous thrombosis. The 67 Ga DFO-DAS-Fibrinogen test proved to be positive in 55 % of arterial thrombin and in 50 % of venous thrombin. It is interesting to note that as high a positivity rate as 80 % was obtained for aortic aneurysm, although the positivity rate was disappointingly low for left atrial thrombin. No distinct correlation was noted to exist between the degree of accumulation of the tracer in thrombotic lesions and any of factors conceivably of clinical releavance, i.e. time elapsing from onset till testing, thrombolytic medication being given, and hematological factors. 67 Ga DFO-DAS-Fibrinogen appeared to be a radiodiagnostic agent that could possibly indicate the existing activity status of thrombosis.

    Many decision problems in Operations Research are defined on temporal networks, that is, workflows of time-consuming tasks whose processing order is constrained by precedence relations. For example, temporal networks are used to model projects, computer applications, digital circuits and production processes. Optimization problems arise in temporal networks when a decision maker wishes to determine a temporal arrangement of the tasks and/or a resource assignment that optimizes some network characteristic (e.g. the time required to complete all tasks). The parameters of these optimization probl

  15. Temporal Ontologies for Geoscience: Alignment Challenges

    Science.gov (United States)

    Cox, S. J. D.

    2014-12-01

    Time is a central concept in geoscience. Geologic histories are composed of sequences of geologic processes and events. Calibration of their timing ties a local history into a broader context, and enables correlation of events between locations. The geologic timescale is standardized in the International Chronostratigraphic Chart, which specifies interval names, and calibrations for the ages of the interval boundaries. Time is also a key concept in the world at large. A number of general purpose temporal ontologies have been developed, both stand-alone and as parts of general purpose or upper ontologies. A temporal ontology for geoscience should apply or extend a suitable general purpose temporal ontology. However, geologic time presents two challenges: Geology involves greater spans of time than in other temporal ontologies, inconsistent with the year-month-day/hour-minute-second formalization that is a basic assumption of most general purpose temporal schemes; The geologic timescale is a temporal topology. Its calibration in terms of an absolute (numeric) scale is a scientific issue in its own right supporting a significant community. In contrast, the general purpose temporal ontologies are premised on exact numeric values for temporal position, and do not allow for temporal topology as a primary structure. We have developed an ontology for the geologic timescale to account for these concerns. It uses the ISO 19108 distinctions between different types of temporal reference system, also linking to an explicit temporal topology model. Stratotypes used in the calibration process are modelled as sampling-features following the ISO 19156 Observations and Measurements model. A joint OGC-W3C harmonization project is underway, with standardization of the W3C OWL-Time ontology as one of its tasks. The insights gained from the geologic timescale ontology will assist in development of a general ontology capable of modelling a richer set of use-cases from geoscience.

  16. Computed tomography of temporal bone fractures and temporal region anatomy in horses.

    In people, specific classifications of temporal bone fractures are associated with clinical signs and prognosis. In horses, similar classifications have not been evaluated and might be useful establishing prognosis or understanding pathogenesis of certain types of trauma. We hypothesized associations between temporal bone fracture location and orientation in horses detected during computed tomography (CT) and frequency of facial nerve (CN7) deficit, vestibulocochlear nerve (CN8) deficit, or temporohyoid osteoarthropathy (THO). Complex temporal region anatomy may confound fracture identification, and consequently a description of normal anatomy was included. All horses undergoing temporal region CT at our hospital between July 1998 and May 2008. Data were collected retrospectively, examiners were blinded, and relationships were investigated among temporal bone fractures, ipsilateral THO, ipsilateral CN7, or ipsilateral CN8 deficits by Chi-square or Fischer's exact tests. Seventy-nine horses had CT examinations of the temporal region (158 temporal bones). Sixteen temporal bone fractures were detected in 14 horses. Cranial nerve deficits were seen with fractures in all parts of the temporal bone (petrosal, squamous, and temporal) and, temporal bone fractures were associated with CN7 and CN8 deficits and THO. No investigated fracture classification scheme, however, was associated with specific cranial nerve deficits. Without knowledge of the regional anatomy, normal structures may be mistaken for a temporal bone fracture or vice versa. Although no fracture classification scheme was associated with the assessed clinical signs, simple descriptive terminology (location and orientation) is recommended for reporting and facilitating future comparisons.

  17. Temporal Convergence for Knowledge Management

    Directory of Open Access Journals (Sweden)

    Christopher Phillip Martin

    2008-05-01

    Full Text Available Time and knowledge have tended to be conceptualised in conventional knowledge management systems as either ‘timeless’ recordings of procedures, or time-stamped records of past events and states. The concept of temporal convergence was previously developed to help apply knowledge-management theory to complex military processes such as commander’s intent, shared situation awareness, and self-synchronisation. This paper clarifies the concept and introduces several others in forming a framework to assist discussion and exploration of the types of knowledge required for complex endeavours, such as warfighting, characterised by opposition and uncertainty. The approach is grounded in a pragmatist philosophy and constructivist epistemology. Argument proceeds along mathematical lines from a basis that the types of knowledge most valuable to goal-directed agents in uncertain environments can be modelled as directed graph topologies. The framework is shown to be useful in describing and reasoning about the knowledge requirements and prerequisites for distributed decision-making through the sharing of situational knowledge and common intentions, with practical application to the planning and execution of operations. To the designers of knowledge management systems seeking to address this space, it presents a challenge that cannot be addressed merely by construction, storage, search and retrieval of documents and records pertaining to the past.

  18. Correlated Temporal and Spectral Variability

    Science.gov (United States)

    Swank, Jean H.

    2007-01-01

    The variability of neutron star and black hole X-ray sources has several dimensions, because of the roles played by different important time-scales. The variations on time scales of hours, weeks, and months, ranging from 50% to orders of magnitude, arise out of changes in the flow in the disk. The most important driving forces for those changes are probably various possible instabilities in the disk, though there may be effects with other dominant causes. The changes in the rate of flow appear to be associated with changes in the flow's configuration, as the accreting material approaches the compact object, for there are generally correlated changes in both the Xray spectra and the character of the faster temporal variability. There has been a lot of progress in tracking these correlations, both for Z and Atoll neutron star low-mass X-ray binaries, and for black hole binaries. I will discuss these correlations and review briefly what they tell us about the physical states of the systems.

    2005-03-01

    In an attempt to determine whether temporal references identified in dreams follow the same temporal distributions as those documented for autobiographical memories, 28 younger women (18-35 years of age) and 30 older women (60-77 years of age) kept a home dream diary for 1 week and then slept 1 night in the laboratory for rapid eye movement sleep dream collection. The following morning, they identified temporal references in their dreams and produced a sample of autobiographical memories using the semantic cuing method. For both groups, there was a linear decrease in temporal references identified in dreams and autobiographical memories with increased remoteness for the last 30 years. As predicted, for the older group, there were similar cubic trends reflecting a disproportionately higher number of both temporal references identified in dreams and autobiographical memories from adolescence/early adulthood compared with adulthood and childhood. The results support the notion of continuity between waking and dreaming memory processes.

O objetivo deste estudo foi demonstrar que competências individuais podem transformar-se em competências coletivas e, nesse nível, predizer o desempenho da equipe. A testagem empírica foi realizada em 51 aeródromos brasileiros, totalizando 106 equipes (entre 3 e 32 integrantes. Instrumentos respondidos pelos membros focaram nas competências enquanto os respondidos pelos lideres indagaram sobre o desempenho das equipes. Os resultados revelaram que as competências coletivas explicam aproximadamente 20% do desempenho das equipes. Disso depreende-se que as competências podem se manifestar como atributos coletivos que predizem resultados de equipes de trabalho.

    Fu, Tianshunag; Imado, Fumiaki

    DAS (Dive and Ascent Satellite) is a kind of satellite that can approach very close to the earth, which was designed by NAL (National Aerospace Laboratory of Japan) in later 1970’s. Now we paid attention to the function of the satellite that can descend and ascend, and proposed to use it for getting detailed information of the area which is suffered from a natural disaster. In this paper orbital control of DAS with minimum fuel consumption is discussed, where the earth is treated as an ellipsoid of revolution, the atmosphere drag and the second zonal coefficient is considered. The optimal orbital control problems are treated as nonlinear two point boundary problems, and solved by the steepest ascent method. The derivation of equations and results are shown in detail.

Uma pesquisa exploratória foi realizada através do estudo de caso de três empresas com ações negociadas na BM&FBOVESPA no período 2006-2009. A partir das demonstrações financeiras das empresas, foram medidos seus desempenhos pelas métricas tradicionais, Retorno sobre Ativo e Retorno sobre Patrimônio Líquido, e pelo RE. O valor das ações de cada empresa foi usado como referência para criação de valor. Um estudo empírico complementar apontou que a correlação entre o RE e o preço das ações foi mais alta e significativa do que a correlação entre os indicadores tradicionais para a empresa mais intensiva em capital intelectual. Para as empresas intensivas em capital físico e em mão de obra, os indicadores de desempenho tradicionais apresentaram correlação mais alta. Sugere-se que a métrica alternativa seja um importante índice para empresas intensivas em capital intelectual. Reforça-se que tal medida de desempenho corporativo, que incorpora o efeito da força de trabalho intelectual, é uma contribuição importante à literatura sobre intangíveis.

Para atender a esse propósito, desenvolveu-se um modelo que, além de oferecer suporte à pesquisa, possa servir de base para estudos e ações sobre internacionalização de empresas de base tecnológica incubadas. O modelo foi elaborado a partir da literatura sobre as duas áreas de interesse do trabalho. De um lado, foram abordadas referências sobre internacionalização de empresas, fazendo-se um levantamento sobre os fatores que influenciam sua internacionalização, principalmente micro e pequenas empresas de base tecnológica; de outro, foram estudados aspectos sobre o processo de incubação de empreendimentos tecnológicos, bem como as ações e os serviços disponibilizados pelas incubadoras.

    Full Text Available RESUMOA higroscopicidade de sementes fornece informações essenciais para otimização de processos de secagem, armazenamento e desenvolvimento de embalagens. O objetivo neste trabalho foi determinar as isotermas de dessorção das sementes de pimenta (Capsicum chinense L., variedade Cabacinha, para diferentes condições de temperatura e atividade de água utilizando-se o método estático indireto, sendo a atividade de água (aw determinada por meio do equipamento Hygropalm Model Aw1. Aos dados experimentais foram ajustados modelos matemáticos frequentemente utilizados para representação da higroscopicidade de produtos agrícolas. Para uma atividade de água constante o aumento da temperatura reduz o teor de água de equilíbrio higroscópico das sementes de pimenta. As isotermas de dessorção apresentam formato sigmoidal do tipo II. Os modelos de Cavalcanti Mata, Chen Clayton, Chung Pfost, Chung Pfost Modificado, Henderson e Henderson Modificado são adequados para representar a higroscopicidade das sementes de pimenta Cabacinha para a faixa de temperatura de 10 a 40 °C e atividade de água de 0,213 a 0,975.

  1. "Doidas e putas”: usos das categorias travesti e transexual

    Directory of Open Access Journals (Sweden)

    Bruno Cesar Barbosa

    Full Text Available Neste artigo discuto os usos das categorias travesti e transexual com base em trabalho de campo realizado entre 2008 e 2009 com participantes das reuniões denominadas Terças Trans. A questão central que norteou a análise foi como as diferentes pessoas observadas utilizavam categorias relacionadas a identidades sexuais e de gênero e como acionavam e articulavam diversas associações convencionais nesse processo para produzir sentidos e diferenças acerca destas categorias. Embora as convenções do discurso médico sejam referências centrais para a definição de corpos, subjetividades e identidades das pessoas pesquisadas, foi possível observar também uma variedade de reelaborações e deslocamentos de sentidos. Procuro desenvolver o argumento de que travesti e transexual são categorias performativas, e que tal performatividade não se esgota apenas em enunciados de gênero e sexualidade, mas também pode ser expressa por meio de articulações contingentes que remetem a diferenças de classe, cor/raça e geração.

Assim, o diagnóstico das tendências sazonais e mensais das chuvas é necessário, principalmente por se tratar de uma região com irregular distribuição espaço-temporal das chuvas. A variação da chuva mensal e sazonal na RSM foi analisada com base em séries climáticas de 45 anos (1960-2004. Aplicou-se na identificação de regiões com chuvas mensais homogêneas a análise de agrupamento (método de Ward. Com base na análise de agrupamento identificaram-se três grupos de estações com chuvas mensais homogêneas (G1, G2 e G3 e outras três estações que não foram agrupadas (NDg. As chuvas apresentaram gradiente espacial negativo na direção de G1 para G3 (nordeste-sudoeste, e totais entre os maiores nas estações do NDg (próximas ao litoral. O período chuvoso mostrou padrão similar, com maior comprimento nas estações do G1 e NDg e, menor nas estações do G3. As variabilidades sazonais e mensais das chuvas na RSM são condicionadas pelos Ciclones Tropicais, Sistemas Frontais, e a influência da Corrente Quente do Canal de Moçambique, enquanto as variabilidades espaciais são, principalmente, definidas pela Zona de Convergência Intertropical.

    This article presents a study that evaluates the effectiveness of a DC link in order to damp power oscillations, of inter area exchange, under small disturbance conditions, operating with Automatic Control Generation. The DC link was represented by a power injection model included the Sensitivity Power Model. Through this representation, the DC link was inserted in the block diagram, modeled as an injection power in the bars terminals in the net active and reactive, closing a new power balance at every instant. It was also designed a controller for damping power oscillations (POD-Power Oscillation Damping Controller) for modulation the power of the DC link and, therefore, insertion of additional damping in a frequency oscillations of exchange lines. The results confirm that the DC link has a great potential for maintaining the damping of oscillations frequency so inter area when equipped with POD controllers.

    Full Text Available Para que o alimento possa cumprir seu papel de mantenedor do estado nutricional dos pacientes, é preciso considerar a composição nutricional, a qualidade microbiológica e os aspectos organolépticos da refeição. Nesse contexto, este estudo teve por objetivo avaliar a temperatura das preparações destinadas aos pacientes de um hospital particular em São Paulo. As refeições são acondicionadas em dois tipos de recipientes: pratos retornáveis e pratos térmicos descartáveis capazes de suportar reaquecimento em forno micro-ondas. Neste trabalho, foram analisadas as dietas oferecidas no almoço e jantar dos pacientes em sete refeições. A temperatura foi aferida na montagem, e antes da entrega ao paciente com um termômetro a laser. Todos os alimentos apresentaram temperaturas corretas ao final da cocção, porém apenas 5,4% das preparações se encontravam em temperatura de segurança no momento da montagem das bandejas dos pacientes. Nas copas, 8,9% das preparações se encontravam abaixo da temperatura correta, após o reaquecimento. Apesar do reaquecimento final possivelmente melhorar a aceitação da dieta, a qualidade microbiológica pode estar comprometida, uma vez que os alimentos foram mantidos em temperatura inadequada entre uma e duas horas. Torna-se necessário investimento em novos equipamentos no local de produção, para evitar perda da temperatura antes da montagem das bandejas com consequente aumento do tempo de exposição dessas preparações em temperaturas inadequadas, além de manutenção preventiva e corretiva dos equipamentos utilizados no local de distribuição, treinamento dos funcionários e monitoramento constante da temperatura durante todo processo produtivo.

    Full Text Available Since the discovery of Bell’s theorem, the physics community has come to take seriously the possibility that the universe might contain physical processes which are spatially nonlocal, but there has been no such revolution with regard to the possibility of temporally nonlocal processes. In this article, we argue that the assumption of temporal locality is actively limiting progress in the field of quantum foundations. We investigate the origins of the assumption, arguing that it has arisen for historical and pragmatic reasons rather than good scientific ones, then explain why temporal locality is in tension with relativity and review some recent results which cast doubt on its validity.

    Full Text Available Este artigo faz parte de uma pesquisa de mestrado que se propõe a analisar conceitos educacionais e curriculares por meio da filosofia da linguagem elaborada por Ludwig Wittgenstein. Dessa perspectiva, examinamos alguns pressupostos teóricos da chamada pedagogia das competências e interrogamos se esse modelo pedagógico, em nome de pretensa renovação do ensino, não encorajaria a reificação de conceitos mentais concernentes ao processo de aprendizagem. Com este fim, abordamos a reformulação que essa pedagogia oferece a respeito de conceitos como aprender, saber, compreender, destacando as ambiguidades daí decorrentes. Argumenta-se que é possível obter uma leitura mais rigorosa das suas propostas de modernização pedagógica se investigarmos o uso dado a esses conceitos nos jogos de linguagem em que eles são mobilizados. Wittgenstein, na segunda fase de sua produção intelectual, mostrou como a negligência linguística à dinâmica que dá significado aos conceitos e metáforas referentes à nossa vida mental fez com que diversas filosofias assumissem um perfil metafísico. Este artigo não apenas examina como um fenômeno análogo pode ocorrer no campo pedagógico, como também defende que as ferramentas analíticas construídas por Wittgenstein podem ser usadas contra os diferentes dogmatismos pedagógicos. Desse modo, o artigo aponta vias alternativas de problematização acerca do significado das reformas dos sistemas escolares que têm buscado fundamentos naquela pedagogia.

  18. The temporal-relevance temporal-uncertainty model of prospective duration judgment.

    Science.gov (United States)

    Zakay, Dan

    2015-12-15

    A model aimed at explaining prospective duration judgments in real life settings (as well as in the laboratory) is presented. The model is based on the assumption that situational meaning is continuously being extracted by humans' perceptual and cognitive information processing systems. Time is one of the important dimensions of situational meaning. Based on the situational meaning, a value for Temporal Relevance is set. Temporal Relevance reflects the importance of temporal aspects for enabling adaptive behavior in a specific moment in time. When Temporal Relevance is above a certain threshold a prospective duration judgment process is evoked automatically. In addition, a search for relevant temporal information is taking place and its outcomes determine the level of Temporal Uncertainty which reflects the degree of knowledge one has regarding temporal aspects of the task to be performed. The levels of Temporal Relevance and Temporal Uncertainty determine the amount of attentional resources allocated for timing by the executive system. The merit of the model is in connecting timing processes with the ongoing general information processing stream. The model rests on findings in various domains which indicate that cognitive-relevance and self-relevance are powerful determinants of resource allocation policy. The feasibility of the model is demonstrated by analyzing various temporal phenomena. Suggestions for further empirical validation of the model are presented. Copyright © 2015 Elsevier Inc.

  5. Compressive Temporal Summation in Human Visual Cortex.

    2018-01-17

    Combining sensory inputs over space and time is fundamental to vision. Population receptive field models have been successful in characterizing spatial encoding throughout the human visual pathways. A parallel question, how visual areas in the human brain process information distributed over time, has received less attention. One challenge is that the most widely used neuroimaging method, fMRI, has coarse temporal resolution compared with the time-scale of neural dynamics. Here, via carefully controlled temporally modulated stimuli, we show that information about temporal processing can be readily derived from fMRI signal amplitudes in male and female subjects. We find that all visual areas exhibit subadditive summation, whereby responses to longer stimuli are less than the linear prediction from briefer stimuli. We also find fMRI evidence that the neural response to two stimuli is reduced for brief interstimulus intervals (indicating adaptation). These effects are more pronounced in visual areas anterior to V1-V3. Finally, we develop a general model that shows how these effects can be captured with two simple operations: temporal summation followed by a compressive nonlinearity. This model operates for arbitrary temporal stimulation patterns and provides a simple and interpretable set of computations that can be used to characterize neural response properties across the visual hierarchy. Importantly, compressive temporal summation directly parallels earlier findings of compressive spatial summation in visual cortex describing responses to stimuli distributed across space. This indicates that, for space and time, cortex uses a similar processing strategy to achieve higher-level and increasingly invariant representations of the visual world. SIGNIFICANCE STATEMENT Combining sensory inputs over time is fundamental to seeing. Two important temporal phenomena are summation, the accumulation of sensory inputs over time, and adaptation, a response reduction for repeated

    The new DSM-5 diagnostic criteria for autism spectrum disorders (ASDs) include sensory disturbances in addition to the well-established language, communication, and social deficits. One sensory disturbance seen in ASD is an impaired ability to integrate multisensory information into a unified percept. This may arise from an underlying impairment in which individuals with ASD have difficulty perceiving the temporal relationship between cross-modal inputs, an important cue for multisensory integration. Such impairments in multisensory processing may cascade into higher-level deficits, impairing day-to-day functioning on tasks, such as speech perception. To investigate multisensory temporal processing deficits in ASD and their links to speech processing, the current study mapped performance on a number of multisensory temporal tasks (with both simple and complex stimuli) onto the ability of individuals with ASD to perceptually bind audiovisual speech signals. High-functioning children with ASD were compared with a group of typically developing children. Performance on the multisensory temporal tasks varied with stimulus complexity for both groups; less precise temporal processing was observed with increasing stimulus complexity. Notably, individuals with ASD showed a speech-specific deficit in multisensory temporal processing. Most importantly, the strength of perceptual binding of audiovisual speech observed in individuals with ASD was strongly related to their low-level multisensory temporal processing abilities. Collectively, the results represent the first to illustrate links between multisensory temporal function and speech processing in ASD, strongly suggesting that deficits in low-level sensory processing may cascade into higher-order domains, such as language and communication.

    Functional magnetic resonance imaging can demonstrate the functional anatomy of cognitive processes. In patients with refractory temporal lobe epilepsy, evaluation of preoperative verbal and visual memory function is important as anterior temporal lobe resections may result in material specific memory impairment, typically verbal memory decline following left and visual memory decline after right anterior temporal lobe resection. This study aimed to investigate reorganization of memory functions in temporal lobe epilepsy and to determine whether preoperative memory functional magnetic resonance imaging may predict memory changes following anterior temporal lobe resection. We studied 72 patients with unilateral medial temporal lobe epilepsy (41 left) and 20 healthy controls. A functional magnetic resonance imaging memory encoding paradigm for pictures, words and faces was used testing verbal and visual memory in a single scanning session on a 3T magnetic resonance imaging scanner. Fifty-four patients subsequently underwent left (29) or right (25) anterior temporal lobe resection. Verbal and design learning were assessed before and 4 months after surgery. Event-related functional magnetic resonance imaging analysis revealed that in left temporal lobe epilepsy, greater left hippocampal activation for word encoding correlated with better verbal memory. In right temporal lobe epilepsy, greater right hippocampal activation for face encoding correlated with better visual memory. In left temporal lobe epilepsy, greater left than right anterior hippocampal activation on word encoding correlated with greater verbal memory decline after left anterior temporal lobe resection, while greater left than right posterior hippocampal activation correlated with better postoperative verbal memory outcome. In right temporal lobe epilepsy, greater right than left anterior hippocampal functional magnetic resonance imaging activation on face encoding predicted greater visual memory decline

    One of the most widely studied perceptual measures of sensory dysfunction in dystonia is the temporal discrimination threshold (TDT) (the shortest interval at which subjects can perceive that there are two stimuli rather than one). However the elevated thresholds described may be due to a number of potential mechanisms as current paradigms test not only temporal discrimination but also extraneous sensory and decision-making parameters. In this study two paradigms designed to better quantify temporal processing are presented and a decision-making model is used to assess the influence of decision strategy. 22 patients with cervical dystonia and 22 age-matched controls completed two tasks (i) temporal resolution (a randomized, automated version of existing TDT paradigms) and (ii) interval discrimination (rating the length of two consecutive intervals). In the temporal resolution task patients had delayed (P = 0.021) and more variable (P = 0.013) response times but equivalent discrimination thresholds. Modelling these effects suggested this was due to an increased perceptual decision boundary in dystonia with patients requiring greater evidence before committing to decisions (P = 0.020). Patient performance on the interval discrimination task was normal. Our work suggests that previously observed abnormalities in TDT may not be due to a selective sensory deficit of temporal processing as decision-making itself is abnormal in cervical dystonia. © 2017 EAN.

    2017-11-03

    Music is a curious example of a temporally patterned acoustic stimulus, and a compelling pan-cultural phenomenon. This review strives to bring some insights from decades of music psychology and sensorimotor synchronization (SMS) literature into the mainstream auditory domain, arguing that musical rhythm perception is shaped in important ways by temporal processing mechanisms in the brain. The feature that unites these disparate disciplines is an appreciation of the central importance of timing, sequencing, and anticipation. Perception of musical rhythms relies on an ability to form temporal predictions, a general feature of temporal processing that is equally relevant to auditory scene analysis, pattern detection, and speech perception. By bringing together findings from the music and auditory literature, we hope to inspire researchers to look beyond the conventions of their respective fields and consider the cross-disciplinary implications of studying auditory temporal sequence processing. We begin by highlighting music as an interesting sound stimulus that may provide clues to how temporal patterning in sound drives perception. Next, we review the SMS literature and discuss possible neural substrates for the perception of, and synchronization to, musical beat. We then move away from music to explore the perceptual effects of rhythmic timing in pattern detection, auditory scene analysis, and speech perception. Finally, we review the neurophysiology of general timing processes that may underlie aspects of the perception of rhythmic patterns. We conclude with a brief summary and outlook for future research.

  12. Pseudoaneurysm of the anterior superficial temporal artery.

    1996-12-01

    Pseudoaneurysm of the superficial temporal artery must be considered in the differential diagnosis of masses of the lateral forehead and temporal fossa. While the first reported case of a temporal artery aneurysm was reported by Thomas Bartholin in 1740, there is scant mention of this lesion in the plastic and maxillofacial surgical literature. Pseudoaneurysms can arise in the forehead and scalp as a result of blunt traumatic impingement of the superficial temporal artery against the calvarium. The anterior branch of the artery is most vulnerable, because in the lateral forehead it courses over the frontal osseous ridge in the galea aponeurotica formed by the fusion line of the deep and superficial temporalis muscle fascia. This dense fascial investment has a tethering effect in the gap between the temporalis and frontalis muscles and prevents the artery from displacing laterally in response to traumatic forces. A history of recent blunt trauma or surgery to the forehead, combined with a pulsatile bruit, should direct the physician to the diagnosis of pseudoaneurysm of the superficial temporal artery. Treatment is surgical resection of the involved segment without the need for reconstruction. This report includes a review of the literature and presents the first documented case of a bicycle helmet as the cause of a superficial temporal artery pseudoaneurysm.

    Temporal integration is the process by which temporally separated visual components are combined into a unified representation. Although this process has been studied in object recognition, little is known about temporal integration in face perception and recognition. In the present study, the authors investigated the characteristics and time boundaries of facial temporal integration. Whole faces of nonfamous and famous people were segmented horizontally into 3 parts and presented in sequence, with varying interval lengths between parts. Inversion and misalignment effects were found at short intervals (0-200 ms). Moreover, their magnitude was comparable to those found with whole-face presentations. These effects were eliminated, or substantially reduced, when the delay interval was 700 ms. Order of parts presentation did not influence the pattern of inversion effects obtained within each temporal delay condition. These results demonstrate that temporal integration of faces occurs in a temporary and limited visual buffer. Moreover, they indicate that only integrated faces can undergo configural processing.

A coleta de dados de produtividade de seis cultivos, entre 2000 e 2005, foi realizada por colhedora equipada com monitor de produtividade. Análises estatísticas e geoestatísticas foram realizadas a fim de avaliar a variabilidade espacial e a presença de dependência espacial ao longo dos anos. A produtividade da soja, do milho e do trigo alcançada apresenta variabilidade com continuidade espacial, correlacionando-se entre si, ao longo dos anos. Em anos de deficit hídrico, verifica-se aumento da variabilidade espacial da produtividade. A cultura do milho é mais eficiente do que a da soja em detectar a variabilidade espacial da produtividade existente na lavoura.The objective of this work was to analyze the spatial and temporal yield variability of soybean, corn and wheat in a 57 ha cropland, without irrigation, under no-till for more than ten years in a Typic Hapludox, located in Palmeira das Missões, RS. Yield data of crops from 2000 to 2005 were collected using a combine equipped with yield monitor. Statistical and geostatistical analysis were performed to monitor the range of the spatial variability and its spatial dependence, as well as its behavior over the years. Soybean, corn and wheat yield present spatial variability, which is maintained over time. In dry years, yield variance coefficient increases compared to wet years. Corn was more efficient than soybean to identify spatial yield variability in the cropland.

    For more than fifteen years electromagnetic fields (EMFs) are intensively discussed in connection with health hazards in mass media as well as questions of standard setting by the authorities. The present elaboration gives an extended overview over the actual situation of the special electromagnetic hypersensitivity issue in relation to electromagnetic field research in the international scientific community. There are parallels and analogies between the symptoms of electromagnetic hypersensitivity and those of the Multiple-Chemical-Sensitivity-Syndrome and other environmental diseases. The first part deals with the biophysical fundamental knowledge of interactions between electromagnetic fields and biological systems such as man or animal including threshold values and threshold philosophy. Then hypothetical mechanisms of action of EMF are demonstrated, with a special focus on the melatonin hypothesis, which has not been proved in all its parts up to now. Additionally, in the context of our biomedical research into disorders of well-being we conducted an analysis of written and telephone questions about the EMF issue which are sent to our center. The results are of scientific and political interest and are demonstrated in detail. (orig.)

Através da realização de entrevistas em profundidade e da observação participante, o artigo analisa as percepções dessas mulheres a respeito das realidades por elas vivenciadas tanto no âmbito produtivo (lavoura como reprodutivo (doméstico. É importante destacar que, em Arroio do Padre, há um processo incipiente de “agroecologização”, ou seja, as unidades familiares encontram-se nos níveis iniciais da transição agroecológica. Já em São Lourenço do Sul, observou-se que essas mulheres atuam na agroecologia há mais de 40 anos. Estas distintas trajetórias conferem percepções de mundo diferenciadas entre os dois contextos sociais. Enquanto para as interlocutoras de Arroio do Padre a agroecologia pouco interfere em suas escolhas dentro e fora de casa, já para as entrevistadas de São Lourenço do Sul é essencial no repensar das relações estabelecidas no lar e no seu entorno, especialmente nos assuntos que tangem aos mercados e a sua valorização enquanto “agricultora”.

    Full Text Available A estratégia para a introdução de uma metodologia nacional de avaliação de impactos ambientais de edifícios iniciou-se quando o Brasil formalizou a sua integração ao projeto Green Building Challenge durante a Conferência Sustainable Building 2000. Desde então novas implementações foram elaboradas para se adequarem ao contexto nacional e refletirem as necessidades da agenda brasileira. Uma nova metodologia desenvolvida por SILVA (2003 ampliou o escopo tradicional de avaliação ambiental para avaliação de sustentabilidade de edifícios através da incorporação de aspectos sócio-econômicos. No entanto uma interface de avaliação ainda está em desenvolvimento. Além disso, a consulta às partes interessadas na construção civil do estado de São Paulo revelou a carência de ferramentas de orientação para o mercado no ciclo de vida das edificações, principalmente para a etapa de projeto. O objetivo deste trabalho é, portanto, definir diretrizes para a sustentabilidade das edificações capazes de orientar clientes, incorporadores, projetistas, construtores, fornecedores e usuários na tomada de decisões em cada fase do ciclo de vida do empreendimento. Para cumprir com o objetivo proposto foi elaborada uma planilha de diretrizes para a sustentabilidade das edificações que foram aplicadas em um estudo de caso demonstrando como esta ferramenta contribui na busca de metas sustentáveis. Palavras-chave: diretrizes, edifícios, sustentabilidade.

    Widespread changes involving neocortical and mesial temporal lobe structures can be present in patients with temporal lobe epilepsy and hippocampal sclerosis. The incidence, pathology, and clinical significance of neocortical temporal lobe sclerosis (TLS) are not well characterized. We identified TLS in 30 of 272 surgically treated cases of hippocampal sclerosis. Temporal lobe sclerosis was defined by variable reduction of neurons from cortical layers II/III and laminar gliosis; it was typically accompanied by additional architectural abnormalities of layer II, that is, abnormal neuronal orientation and aggregation. Quantitative analysis including tessellation methods for the distribution of layer II neurons supported these observations. In 40% of cases, there was a gradient of TLS with more severe involvement toward the temporal pole, possibly signifying involvement of hippocampal projection pathways. There was a history of a febrile seizure as an initial precipitating injury in 73% of patients with TLS compared with 36% without TLS; no other clinical differences between TLS and non-TLS cases were identified. Temporal lobe sclerosis was not evident preoperatively by neuroimaging. No obvious effect of TLS on seizure outcome was noted after temporal lobe resection; 73% became seizure-free at 2-year follow-up. In conclusion, approximately 11% of surgically treated hippocampal sclerosis is accompanied by TLS. Temporal lobe sclerosis is likely an acquired process with accompanying reorganizational dysplasia and an extension of mesial temporal sclerosis rather than a separate pathological entity.

    We present our approach to speech therapy developed for patients with definitive peripheral facial palsy treated by temporal lengthening myoplasty. The main goal is to rehabilitate smiling function, a major component in social communication codes, by transferring labial and jugal functions to the transferred temporal muscle. Several phases are involved. The first phase, termed the Mandibular Smile involves mobilization of the mandible (original function of the temporal) by contraction of the transferred temporal and inducing an elevation of the commissura labiorum. The second phase, the Voluntary Temporal Smile is obtained by contraction of the temporal independently of mandibular movement which remains under voluntary control. The smile produces should become as symmetrical as possible. Finally, the last phase is designed to achieve a spontaneous smile independent of mandibular movement Spontaneous Temporal Smile. Temporal contraction should produce both a "real" expressive smile and good quality articulate speech, saliva evacuation, prehension, and labial junction. Acquisition of the Temporal Smile involves cerebral plasticity implying rehabilitation processes both on the peripheral and central levels.

Utilizando-se de uma abordagem qualitativa numa pesquisa bibliográfica, procura-se demonstrar que o referido filósofo desenvolve sua apreciação do assunto em tela a partir de pressupostos que conduzem-no a concluir que as ciências e artes promovem mais vícios que virtudes, tanto para os indivíduos quanto para as sociedades. Apesar desta situação, ele acredita ser possível que ambas sejam causa do bem, uma vez que a causa da corrupção delas está ligada ao modo como a sociedade, e em particular quem detém o poder, lida com o Saber.

    Full Text Available Este artigo examina os conteúdos das alucinações visuais induzidas pela infusão psicotrópica ayahuasca. Ele faz parte de uma investigação fenomenológica mais ampla que busca estudar a ayahuasca de uma perspectiva psicológico-cognitiva. (Até agora, quase todos os estudos da ayahuasca partiram das ciências naturais ou da antropologia. Análises comparativas quantitativas revelam que certos itens de conteúdo específico são especialmente prevalescentes em visões da ayahuasca e se reencontram em relatos de informantes de diferentes origens socioculturais. Os resultados são discutidos teoricamente à luz de considerações tanto psicológicas como antropológicas.This paper examines the contents of the visual hallucinations induced by the Amazonian psychotropic brew ayahuasca. It is part of a comprehensive phenomenological investigation attempting to study ayahuasca from a cognitive-psychological perspective. (So far, practically all studies of ayahuasca pertained either to the natural sciences or to anthropology. Comparative quantitative analyses reveal that some specific content items are especially prevalent in ayahuasca visions, and that these are encountered in the reports of informants from different personal and socio-cultural backgrounds. Theoretically, the findings are discussed in light of both psychological and anthropological considerations.

    Nerlich, Mark R.; Schiffner, Felix; Vogt, Walter

    Mit Daten aus eigenen Erhebungen können das einkaufsbezogene Informations- und Einkaufsverhalten im Zusammenhang mit den verkehrlichen Aspekten (Distanzen, Verkehrsmittel, Wegekopplungen) dargestellt werden. Die Differenzierung in die drei Produktkategorien des täglichen, mittelfristigen und des langfristigen Bedarfs berücksichtigt in erster Linie die Wertigkeit eines Gutes, die seine Erwerbshäufigkeit unmittelbar bestimmt. Der Einsatz moderner IKT wie das Internet eröffnet dem Endverbraucher neue Möglichkeiten bei Information und Einkauf. Die verkehrliche Relevanz von Online-Shopping wird deutlich, wenn man berücksichtigt, dass im Mittel rund 17% aller Online-Einkäufe, die die Probanden durchgeführt haben, Einkäufe in Ladengeschäften ersetzen. Dies gilt in verstärktem Maße für Online-Informationen: etwa die Hälfte hätte alternativ im stationären Einzelhandel stattgefunden. Da der Erwerb von Gütern des täglichen Bedarfs häufig nahräumlich und in relevantem Anteil nicht-motorisiert erfolgen kann, sind in diesem Segment - im Gegensatz zum mittel- und langfristigen Bedarf - nur geringe Substitutionseffekte zu beobachten.

    1.Within natural communities, different taxa display different dynamics in time. Why this is the case we do not fully know. This thwarts our ability to predict changes in community structure, which is important for both the conservation of rare species in natural communities and for the prediction of pest outbreaks in agriculture. 2.Species sharing phylogeny, natural enemies and/or life history traits have been hypothesized to share similar temporal dynamics. We operationalized these concepts into testing whether feeding guild, voltinism, similarity in parasitoid community, and/or phylogenetic relatedness explained similarities in temporal dynamics among herbivorous community members. 3.Focusing on two similar data sets from different geographical regions (Finland and Japan), we used asymmetric eigenvector maps as temporal variables to characterize species- and community-level dynamics of specialist insect herbivores on oak (Quercus). We then assessed whether feeding guild, voltinism, similarity in parasitoid community, and/or phylogenetic relatedness explained similarities in temporal dynamics among taxa. 4.Species-specific temporal dynamics varied widely, ranging from directional decline or increase to more complex patterns. Phylogeny was a clear predictor of similarity in temporal dynamics at the Finnish site, whereas for the Japanese site, the data were uninformative regarding a phylogenetic imprint. Voltinism, feeding guild and parasitoid overlap explained little variation at either location. Despite the rapid temporal dynamics observed at the level of individual species, these changes did not translate into any consistent temporal changes at the community level in either Finland or Japan. 5.Overall, our findings offer no direct support for the notion that species sharing natural enemies and/or life history traits would be characterised by similar temporal dynamics, but reveal a strong imprint of phylogenetic relatedness. As this phylogenetic signal cannot be

  3. The medial temporal lobe: memory and beyond.

    2013-10-01

    The structures of the medial temporal lobe, e.g., the hippocampus, entorhinal cortex, perirhinal cortex, and parahippocampal cortex, are known to be essential for long-term memory processing and hence are labeled the medial temporal lobe memory system. Nevertheless, the exact contributions of each structure and the involvement in different cognitive processes remain controversial. This article discusses recent findings dealing with recognition memory and a long lasting involvement of the hippocampus and perirhinal cortex in episodic memory, based on functional imaging and lesion studies. Furthermore, a new paradigm employing objective manipulations of recollection and familiarity is presented, showing no anatomical distinction for these two processes, as opposed to studies using subjective ratings. Additionally, results regarding an involvement of the medial temporal lobe in visual processing are presented, in general supporting the visual-mnemonic theory. The discussed findings show that many questions regarding the functional organization remain unsolved, and that we are in need of further research to create a comprehensive model of the medial temporal lobe. For this, we might need to give up the distinctions into different cognitive processes and start to investigate the different types of representations that are processed by the medial temporal lobe.

    Full Text Available Creation problem of model of grammatical means of temporality expression in translation from English into Kazakh and Russian languages is considered in the article. At a choice of translation of transformations of aspectual-temporal categories of a verb from English into Kazakh and Russian languages it is considered not only grammatical compliance of categories of tense, but also the contextual use of a functional and semantic field of verbs, comparison of lexical temporality with positions of concepts, specific to each language world picture, with positions of modern philosophy and logic of language. Authors come to a conclusion that productive use of analytical forms in the Kazakh and English languages is the result of structural features of categories of tense and a type of English and Kazakh languages. Comparison of a phase of actions of a verb in English and Kazakh languages allows creation of reference model of grammatical means of expression of temporality in translation from English into Kazakh and Russian languages on the basis of a functional and semantic field of verbs, comparison of lexical temporality from positions specific on each language picture of the world.

Analisaram-se séries históricas pluviométricas de 97 postos pluviométricos, compreendendo o período de 1985 a 2009. A erosividade foi estimada por meio de equações nas quais a variável independente foi a precipitação média mensal ou o coeficiente de chuva de Fournier (Rc. A geoestatística foi aplicada para o mapeamento da erosividade tanto na escala mensal quanto na anual. A erosividade anual apresentou valores entre 6.599 e 14.000 MJ mm ha-1 h-1, com auge em dezembro, quando atingiu valores de até 2.800 MJ mm ha-1 h-1 por mês. De maio a setembro, a erosividade apresentou valores inferiores ao crítico, tido como 500 MJ mm ha-1 h-1 por mês. Foram identificadas três regiões prioritárias para ações de planejamento visando a conservação do solo e da água: região centro-oeste do Estado, nas imediações do Parque Estadual do Cantão, com maior erosividade anual; região norte do Estado, especialmente no primeiro trimestre; e região sudeste do Estado, no quarto trimestre.

    To investigate dynamic ictal perfusion changes during temporal lobe epilepsy (TLE). We investigated 37 patients with TLE by ictal and interictal SPECT. All ictal injections were performed within 60 s of seizure onset. Statistical parametric mapping was used to analyse brain perfusion changes and temporal relationships with injection time and seizure duration as covariates. The analysis revealed significant ictal hyperperfusion in the ipsilateral temporal lobe extending to subcortical regions. Hypoperfusion was observed in large extratemporal areas. There were also significant dynamic changes in several extratemporal regions: ipsilateral orbitofrontal and bilateral superior frontal gyri and the contralateral cerebellum and ipsilateral striatum. The study demonstrated early dynamic perfusion changes in extratemporal regions probably involved in both propagation of epileptic activity and initiation of inhibitory mechanisms. (orig.)

    Full Text Available Facial attractiveness is an important biological and social signal on social interaction. Recent research has demonstrated that an attractive face captures greater spatial attention than an unattractive face does. Little is known, however, about the temporal characteristics of visual attention for facial attractiveness. In this study, we investigated the temporal modulation of visual attention induced by facial attractiveness by using a rapid serial visual presentation (RSVP. Fourteen male faces and two female faces were successively presented for 160 ms respectively, and participants were asked to identify two female faces embedded among a series of multiple male distractor faces. Identification of a second female target (T2 was impaired when a first target (T1 was attractive compared to neutral or unattractive faces, at 320 ms SOA; identification was improved when T1 was attractive compared to unattractive faces at 640 ms SOA. These findings suggest that the spontaneous appraisal of facial attractiveness modulates temporal attention.

  10. Dreams and the temporality of consciousness.

    Science.gov (United States)

    MacDuffie, Katherine; Mashour, George A

    2010-01-01

    Understanding dreams has long been considered fundamental to the development of a theory of consciousness. Evidence from neurobiology and neuroimaging research has paved the way for new theories of dreaming that are empirically supported. In this article we argue that dreaming is a unique state of consciousness that incorporates 3 temporal dimensions: experience of the present, processing of the past, and preparation for the future. The temporal complexity of dreams is made possible in part by the unique neurobiological environment of sleep, in which stimuli are internally generated and many of the restrictions associated with waking thought are absent. Because dream consciousness is not determined by sensory stimuli, a flexible integration of past experiences and the forging of novel connections are possible. We argue that disparate dream theories may not be mutually exclusive but rather relate to different temporal domains of the dream state.

  11. What Is Spatio-Temporal Data Warehousing?

    Science.gov (United States)

    Vaisman, Alejandro; Zimányi, Esteban

    In the last years, extending OLAP (On-Line Analytical Processing) systems with spatial and temporal features has attracted the attention of the GIS (Geographic Information Systems) and database communities. However, there is no a commonly agreed definition of what is a spatio-temporal data warehouse and what functionality such a data warehouse should support. Further, the solutions proposed in the literature vary considerably in the kind of data that can be represented as well as the kind of queries that can be expressed. In this paper we present a conceptual framework for defining spatio-temporal data warehouses using an extensible data type system. We also define a taxonomy of different classes of queries of increasing expressive power, and show how to express such queries using an extension of the tuple relational calculus with aggregated functions.

    2008-01-01

    In literature, existing researches on building recognition mainly concentrate on scales, rotations, and viewpoints variance. In urban environment, large temporal variations of weather and lighting conditions should also be considered as major challenges for robust recognition. For instances......, there are differences between images captured during daytime and nighttime, especially significant changes in building appearances between seasons because of the differences in light setting. To date, these large temporal variation issues have not been fully investigated. In this paper, we therefore focus...... on constructing a system that deals with the temporal difference factors in recognizing urban buildings. In order to build such a system, two main criteria are raised, namely the efficiency of the recognition algorithm and the speed for interactive search purpose. For recognition purpose, we exploit the MOPS...

  18. Error and attack vulnerability of temporal networks

    Science.gov (United States)

    Trajanovski, S.; Scellato, S.; Leontiadis, I.

    2012-06-01

    The study of real-world communication systems via complex network models has greatly expanded our understanding on how information flows, even in completely decentralized architectures such as mobile wireless networks. Nonetheless, static network models cannot capture the time-varying aspects and, therefore, various temporal metrics have been introduced. In this paper, we investigate the robustness of time-varying networks under various failures and intelligent attacks. We adopt a methodology to evaluate the impact of such events on the network connectivity by employing temporal metrics in order to select and remove nodes based on how critical they are considered for the network. We also define the temporal robustness range, a new metric that quantifies the disruption caused by an attack strategy to a given temporal network. Our results show that in real-world networks, where some nodes are more dominant than others, temporal connectivity is significantly more affected by intelligent attacks than by random failures. Moreover, different intelligent attack strategies have a similar effect on the robustness: even small subsets of highly connected nodes act as a bottleneck in the temporal information flow, becoming critical weak points of the entire system. Additionally, the same nodes are the most important across a range of different importance metrics, expressing the correlation between highly connected nodes and those that trigger most of the changes in the optimal information spreading. Contrarily, we show that in randomly generated networks, where all the nodes have similar properties, random errors and intelligent attacks exhibit similar behavior. These conclusions may help us in design of more robust systems and fault-tolerant network architectures.

Os resultados reportados sugerem que a baixa elasticidade-preço das importações agregadas reflete fundamentalmente a baixa elasticidade-preço das importações de combustíveis, bens intermediários e de alguns tipos de serviços - notadamente, transporte, aluguel de equipamentos e pagamentos de royalties - produtos que, somados, respondem por pouco menos de dois terços do total importado. Isso ocorre porque vários desses produtos têm pouca ou nenhuma possibilidade de substituição por similares nacionais, devido principalmente a deficiências estruturais na oferta nacional.

  1. Statistical Mechanics of Temporal and Interacting Networks

    Zhao, Kun

    In the last ten years important breakthroughs in the understanding of the topology of complexity have been made in the framework of network science. Indeed it has been found that many networks belong to the universality classes called small-world networks or scale-free networks. Moreover it was found that the complex architecture of real world networks strongly affects the critical phenomena defined on these structures. Nevertheless the main focus of the research has been the characterization of single and static networks. Recently, temporal networks and interacting networks have attracted large interest. Indeed many networks are interacting or formed by a multilayer structure. Example of these networks are found in social networks where an individual might be at the same time part of different social networks, in economic and financial networks, in physiology or in infrastructure systems. Moreover, many networks are temporal, i.e. the links appear and disappear on the fast time scale. Examples of these networks are social networks of contacts such as face-to-face interactions or mobile-phone communication, the time-dependent correlations in the brain activity and etc. Understanding the evolution of temporal and multilayer networks and characterizing critical phenomena in these systems is crucial if we want to describe, predict and control the dynamics of complex system. In this thesis, we investigate several statistical mechanics models of temporal and interacting networks, to shed light on the dynamics of this new generation of complex networks. First, we investigate a model of temporal social networks aimed at characterizing human social interactions such as face-to-face interactions and phone-call communication. Indeed thanks to the availability of data on these interactions, we are now in the position to compare the proposed model to the real data finding good agreement. Second, we investigate the entropy of temporal networks and growing networks , to provide

  2. Controlling Laser Plasma Instabilities Using Temporal Bandwidth

    2016-10-01

    We are performing particle-in-cell simulations using the code OSIRIS to study the effects of laser plasma interactions in the presence of temporal bandwidth under conditions relevant to current and future experiments on the NIKE laser. Our simulations show that, for sufficiently large bandwidth (where the inverse bandwidth is comparable with the linear growth time), the saturation level, and the distribution of hot electrons, can be effected by the addition of temporal bandwidths (which can be accomplished in experiments using beam smoothing techniques such as ISI). We will quantify these effects and investigate higher dimensional effects such as laser speckles. This work is supported by DOE and NRL.

    In literature, existing researches on building recognition mainly concentrate on scales, rotations, and viewpoints variance. In urban environment, large temporal variations of weather and lighting conditions should also be considered as major challenges for robust recognition. For instances...... on constructing a system that deals with the temporal difference factors in recognizing urban buildings. In order to build such a system, two main criteria are raised, namely the efficiency of the recognition algorithm and the speed for interactive search purpose.

    This is a report of two cases of spontaneous temporal encephalocele: one was anteroinferior and presented with epilepsy; the other was posteroinferior and presented with facial neuritis and labyrinthitis. Spontaneous temporal encephalocele is relatively rare and apparently not familiar to a majority of primary physicians. It may present with a variety of symptoms according to its anatomical location, including cerebrospinal fluid fistulas, recurrent meningitis, chronic otitis media, hearing loss, facial nerve palsy and medically intractable epilepsy. Attention should be paid to this disease entity, as it is easily overlooked in imaging studies and can leave serious neurological deficits. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Full Text Available Identifying a temporal pattern of events is a fundamental task of online (real-time verification. We present efficient schemes for online monitoring of events for identifying desired/undesired patterns of events. The schemes use preprocessing to ensure that the number of comparisons during run-time is minimized. In particular, the first comparison following the time point when an execution sub-sequence cannot be further extended to satisfy the temporal requirements halts the process that monitors the sub-sequence.

    2014-09-01

    Full Text Available Der strukturelle Budgetsaldo ist eine zentrale Kontrollgröße im EU-Fiskalregelwerk. Vor dem Hintergrund der rechtlichen Bindung der Fiskalpolitik über diese für Konjunktur- und Einmaleffekte korrigierte Budgetgröße sind jedoch erhebliche Prognoseabweichungen und Ex-post-Ergebniskorrekturen bei der Berechnung des strukturellen Budgetsaldos zu problematisieren. Dieses Papier beleuchtet diese Revisionen im Hinblick auf die zugrunde liegenden methodischen Probleme und diskutiert die politischen Implikationen. Das zentrale methodische Problem besteht in der Schätzung des Output-Potenzials. Die Europäische Kommission unterschätzte in den letzten Jahren die negativen Outputlücken, was eine Überschätzung der strukturellen Defizite zur Folge hat. Eine strikte rechtliche Bindung des Gesamtstaates an strukturelle Budgetregelgrenzen, die Vorgaben bis auf die zweite Nachkommastelle beinhalten, erscheint angesichts der hohen Revisionsanfälligkeit des strukturellen Budgetsaldos somit als problematisch.

    Full Text Available The article "The Visual Imagination of Paul Celan - das Aug, dunkel" raises the problem of the poet's search for language and "the place, from where you can see the best perspective". It shows the number of methodological dilemmas which inevitably result from analysing the visual imagination. It speaks of "the eye" understood as the crucial element of Celan's poetics. The author questions in his article the common percepcion of Celan as a poet of Shoah (as if shifting the momentum to the eye. The eye, reduced in the very grammatical form of the word (Auge is turned into Aug, gives the unity to Celan's work. The eye, the restless wanderer, accompanies this poetry from the first to the last poem. The author of the article ventures to elucidate various aspects of the use of the organ of vision in Celan's poetry and draws a conclusion that the consistent theory of visual perception is central to Celan's work.

Ellen Wood, Jürgen Habermas, Boaventura de Sousa Santos e Claus Offe são convocados para a terefa de esclarecimento do polissêmico conceito de democracia e expressar a crise mesma do fenômeno que se busca nomear, portanto, das idéias de representação e de participação, das relações entre o político e o econômico, entre o mercado e a cidadania. Os quatro autores indicam os limites inextricáveis no fazer democrático do modelo representativo liberal e expõem diagnósticos e prognósticos distintos, complementares ou mesmo antagônicos que buscamos sistematizar. As matrizes teóricas anunciadas permitiram-nos a reconstrução de modelos de democracia: a democracia radical de Wood em sua crítica nodal ao capitalismo como organizador da vida em sociedade; a democracia procedural ou deliberacionista de Habermas que visa à síntese dos modelos liberal e republicano sem os vícios destes; a democracia participativa Sousa Santos e sua aposta num novo contrato social e recriar o Estado; a democracia liberal reformada de Offe no capitalismo desorganizado pós-welfare. O debate em torno destas propostas de democracia, por fim, sugere pistas na renegociação da democracia em contextos pós-nacionais

As razões para esta implicação de governos subnacionais no cenário externo são vinculadas tanto às mudanças que ocorreram na esfera internacional, às reformas no interior dos Estados, quanto às modificações que têm lugar no comportamento dos governos subnacionais. A proposta deste artigo é analisar o conflito, resultante da construção de usinas Papeleras, de uma conjunção entre o governo nacional argentino, o governo provincial de Entre Ríos e setores da sociedade civil de Gualeguaychú contra o governo uruguaio. O caso das papeleras revela-se um objeto de pesquisa que reflete os desafios enfrentados pelo Estado-nação na contemporaneidade. Esses desafios perpassam: (i a questão da governance, a saber, uma forma ótima de gerenciar problemas socioeconômicos aliando mecanismos políticos de legitimidade e dispositivos econômicos eficientes; (ii o tema da emergência paulatina de níveis concorrentes de gerenciamento da coisa pública em nível global, os agentes infraestatais despontando como vetor de legitimidade da ação cidadã; (iii o tópico relativo à ecologia e a seu regime internacional ativo balizando a tendência de reformulação da concepção do conceito de soberania, tanto no seu flanco interno, quanto no externo.

A monitorização video-eletrencefalográfica de uma paciente com 34 anos de idade que apresentava episódios de perda de consciência permitiu a detecção de períodos de assistolia como principal manifestação clínica, exigindo a implantação de marca-passo. O registro eletrencefalográfico concomitante mostrou atividade rítmica a 6-7 Hz de projeção na região temporal esquerda. A ressonância magnética mostrou lesão expansiva no giro para-hipocampal esquerdo. Alterações do ritmo cardíaco como taquicardia sinusal são frequentes em crises epilépticas. A descrição de bradicardia e/ou assistolia é rara. As conexões das estruturas mesiais temporais com estruturas profundas como o hipotálamo devem ser responsáveis pelas manifestações vegetativas durante crises epilépticas temporais.We describe a patient who had cardiac arrhythmia as epileptic manifestation. In a 34-year-old woman who had many episodes of loss of consciousness, the simultaneous ECG and video-EEG monitoring recorded bradycardia with a short episode of asystolia (4 seconds and left temporal rhythmic teta activity on EEG. MRI showed a small mass lesion in the left parahippocampal gyrus. Alterations in cardiac rhythm have been reported in epileptic seizures and taquycardia is the most common finding associated with them; bradyarrhythmia during seizures was uncommon. Many interconnections among insular cortex, limbic system and hypothalamus, may be responsible for vegetative manifestations in temporal lobe epilepsy.

    Full Text Available A questão informacional permeia as mais diversas áreas do conhecimento. Em relação ao ambiente industrial, elevados custos são imputados à indústria em virtude de deficiências no ciclo informacional e no de mercadorias. Falhas ocasionam interrupções e rupturas nesses ciclos, reduzindo a competitividade das organizações. O trabalho debruça-se sobre a possibilidade de categorizar essas falhas na cadeia de suprimentos. O objetivo principal é, a partir de um olhar da Ciência da Informação (CI, propor uma taxonomia para as falhas existentes, tendo por base os seguintes objetivos: (i identificar as principais falhas nas cadeias de suprimentos evidenciadas na literatura; (ii posicionar cada falha dentro do fluxo logístico e informacional, e (iii agrupar, organizar e hierarquizar essas falhas. Trata-se uma pesquisa bibliográfica, exploratória e qualitativa. Os resultados obtidos permitem afirmar que existem diversas similaridades nos termos que definem os locais e a origem das ocorrências de falhas, assim como, a percepção de que, com base na taxonomia proposta, há elevados riscos de interrupções e rupturas na cadeia de suprimentos. Finalmente, com o trabalho, espera-se contribuir com a ampliação da compreensão das falhas que acometem diversas organizações e, igualmente, com a geração de conhecimento para discussões futuras que envolvam as cadeias de suprimentos e a Ciência da Informação. Há um vasto espaço de colaboração no que tange à questão informacional na cadeia de suprimentos, que ainda não está devidamente preenchido pela CI.

  13. Non-verbal auditory cognition in patients with temporal epilepsy before and after anterior temporal lobectomy

    Full Text Available For patients with pharmaco-resistant temporal epilepsy, unilateral anterior temporal lobectomy (ATL - i.e. the surgical resection of the hippocampus, the amygdala, the temporal pole and the most anterior part of the temporal gyri - is an efficient treatment. There is growing evidence that anterior regions of the temporal lobe are involved in the integration and short-term memorization of object-related sound properties. However, non-verbal auditory processing in patients with temporal lobe epilepsy (TLE has raised little attention. To assess non-verbal auditory cognition in patients with temporal epilepsy both before and after unilateral ATL, we developed a set of non-verbal auditory tests, including environmental sounds. We could evaluate auditory semantic identification, acoustic and object-related short-term memory, and sound extraction from a sound mixture. The performances of 26 TLE patients before and/or after ATL were compared to those of 18 healthy subjects. Patients before and after ATL were found to present with similar deficits in pitch retention, and in identification and short-term memorisation of environmental sounds, whereas not being impaired in basic acoustic processing compared to healthy subjects. It is most likely that the deficits observed before and after ATL are related to epileptic neuropathological processes. Therefore, in patients with drug-resistant TLE, ATL seems to significantly improve seizure control without producing additional auditory deficits.

    Full Text Available Large ports need to deal with a number of disparate activities:the movement of ships, containers and other cargo, theloading and unloading of ships and containers, customs activities.As well as human resources, anchorages, channels, lighters,tugs, berths, warehouse and other storage spaces have to beallocated and released. The efficient management of a port involvesmanaging these activities and resources, managing theflows of money involved between the agents providing and usingthese resources, and providing management information.Many information systems will be involved.Many applications have to deal with a large amount of datawhich not only represent the perceived state of the real world atpresent, but also past and/or future states. These applicationsare not served adequately by today's computer managementand database systems. In particular, deletions and updates insuch systems have destructive semantics. This means that previousdatabase contents (representing previous perceived statesof the real world cannot be accessed anymore.A review of how define temporal data models, based ongeneralizing a non-temporal data model in to a temporal one toimprove port management is presented. This paper describes apractical experiment which supports managing temporal dataalong with the corresponding prototype implementations.

  19. Anterior Temporal Lobe Morphometry Predicts Categorization Ability

    Directory of Open Access Journals (Sweden)

    Béatrice Garcin

    2018-02-01

    Full Text Available Categorization is the mental operation by which the brain classifies objects and events. It is classically assessed using semantic and non-semantic matching or sorting tasks. These tasks show a high variability in performance across healthy controls and the cerebral bases supporting this variability remain unknown. In this study we performed a voxel-based morphometry study to explore the relationships between semantic and shape categorization tasks and brain morphometric differences in 50 controls. We found significant correlation between categorization performance and the volume of the gray matter in the right anterior middle and inferior temporal gyri. Semantic categorization tasks were associated with more rostral temporal regions than shape categorization tasks. A significant relationship was also shown between white matter volume in the right temporal lobe and performance in the semantic tasks. Tractography revealed that this white matter region involved several projection and association fibers, including the arcuate fasciculus, inferior fronto-occipital fasciculus, uncinate fasciculus, and inferior longitudinal fasciculus. These results suggest that categorization abilities are supported by the anterior portion of the right temporal lobe and its interaction with other areas.

    Redfearn, A.; Pimm, S.L.

    1993-01-01

    Ecologists use the term 'stability' to mean to number of different things (Pimm 1984a). One use is to equate stability with low variability in population density over time (henceforth, temporal variability). Temporal variability varies greatly from species to species, so what effects it? There are at least three sets of factors: the variability of extrinsic abiotic factors, food web structure, and the intrinsic features of the species themselves. We can measure temporal variability using at least three statistics: the coefficient of variation of density (CV); the standard deviation of the logarithms of density (SDL); and the variance in the differences between logarithms of density for pairs of consecutive years (called annual variability, hence AV, b y Wolda 1978). There are advantages and disadvantages to each measure (Williamson 1984), though in our experience, the measures are strongly correlated across sets of taxonomically related species. The increasing availability of long-term data sets allows one to calculate these statistics for many species and so to begin to understand the various causes of species differences in temporal variability

  11. High resolution CT of temporal bone trauma

    Youn, Eun Kyung

    1986-01-01

    Radiographic studies of the temporal bone following head trauma are indicated when there is cerebrospinal fluid otorrhea or rhinorrhoea, hearing loss, or facial nerve paralysis. Plain radiography displays only 17-30% of temporal bone fractures and pluridirectional tomography is both difficult to perform, particularly in the acutely ill patient, and less satisfactory for the demonstration of fine fractures. Consequently, high resolution CT is the imaging method of choice for the investigation of suspected temporal bone trauma and allows special resolution of fine bony detail comparable to that attainable by conventional tomography. Eight cases of temporal bone trauma examined at Korea General Hospital April 1985 through May 1986. The results were as follows: Seven patients (87%) suffered longitudinal fractures. In 6 patients who had purely conductive hearing loss, CT revealed various ossicular chain abnormality. In one patient who had neuro sensory hearing loss, CT demonstrated intract ossicular with a fracture nearing lateral wall of the lateral semicircular canal. In one patient who had mixed hearing loss, CT showed complex fracture.

    the Random Gap Detection Test (RGDT) evaluates temporal resolution threshold. There are doubts as to whether performance in this task remains unchanged with the aging process. At the same time, there is a concern about how much the difficulties of communication experienced by elderly individuals are related to the deterioration of temporal resolution. to determine auditory temporal resolution threshold in elderly individuals with normal peripheral hearing or symmetric mild sensorineural hearing loss, and to correlate findings with gender, age, audiometric findings and scores obtained in the Self - Assessment of Communication (SAC) questionnaire. 63 elderly individuals, aged between 60 and 80 years (53 women and 10 men), were submitted to the RGDT and the SAC. statistical analysis of the relationship between gender and the RGDT indicated that the performance of elderly females was statistically poorer when compared to elderly males. Age and audiometric configuration did not correlate to performance in the RDGT and in the SAC. The results indicate that in the SAC both genders presented no significant complaints about communication difficulties regardless of the outcome obtained in the RGDT or audiometric configuration. the average temporal resolution threshold for women was 104.81ms. Considering gender, females did not present correlations between age and audiometric configuration, not only when considering the RGDT results but also when analyzing the SAC results.

    2012-09-01

    Full Text Available Abstract Background Cerebral cortex has a very large number of testosterone receptors, which could be a basis for sex differences in sensory functions. For example, audition has clear sex differences, which are related to serum testosterone levels. Of all major sensory systems only vision has not been examined for sex differences, which is surprising because occipital lobe (primary visual projection area may have the highest density of testosterone receptors in the cortex. We have examined a basic visual function: spatial and temporal pattern resolution and acuity. Methods We tested large groups of young adults with normal vision. They were screened with a battery of standard tests that examined acuity, color vision, and stereopsis. We sampled the visual system’s contrast-sensitivity function (CSF across the entire spatio-temporal space: 6 spatial frequencies at each of 5 temporal rates. Stimuli were gratings with sinusoidal luminance profiles generated on a special-purpose computer screen; their contrast was also sinusoidally modulated in time. We measured threshold contrasts using a criterion-free (forced-choice, adaptive psychophysical method (QUEST algorithm. Also, each individual’s acuity limit was estimated by fitting his or her data with a model and extrapolating to find the spatial frequency corresponding to 100% contrast. Results At a very low temporal rate, the spatial CSF was the canonical inverted-U; but for higher temporal rates, the maxima of the spatial CSFs shifted: Observers lost sensitivity at high spatial frequencies and gained sensitivity at low frequencies; also, all the maxima of the CSFs shifted by about the same amount in spatial frequency. Main effect: there was a significant (ANOVA sex difference. Across the entire spatio-temporal domain, males were more sensitive, especially at higher spatial frequencies; similarly males had significantly better acuity at all temporal rates.

    Full Text Available Os autores estudaram do ponto de vista psiquiátrico, no pré e no pós-operatório, série de 31 casos operados por epilepsia temporal incontrolável. Esta, com seu substrato fisiopatológico, está associada a irritabilidade patológica, tenacidade afetiva, impulsividade, disfunção cognitiva epiléptica e deficiências de abstração nos processos intelectuais. As altas incidências dessas psicopatologias nos doentes estudados demonstram essa associação e sugerem fortemente a existência de relação causal entre elas e a epilepsia temporal. As lobectomias temporais unilaterais se mostraram eficazes para o controle das crises epilépticas, cuja freqüência se reduziu intensamente no pós-operatório. As cirurgias promoveram intensa e útil redução nas manifestações da irritabilidade patológica, da impulsividade, da disfunção cognitiva epiléptica e das instabilidades da capacidade de abstração promovidas por impactos afetivos. A tenacidade afetiva foi pouco alterada pelas operações, embora tenha ocorrido efeito favorável. Incapacidades de abstração, estáveis, não foram afetadas pelas cirurgias. A presença de focos em ambos os lobos temporais não diminuiu a eficácia da cirurgia, nem quanto a seu efeito sobre as crises, nem quanto a seu efeito sobre as alterações psicopatológicas estudadas.

    2016-01-01

    Medial temporal lobe epilepsy associated with mesial temporal sclerosis (MTS) is perhaps the most well-defined epilepsy syndrome that is responsive to structural interventions such as surgery. Several minimally invasive techniques have arisen that provide additional options for the treatment of MTS while potentially avoiding many of open surgery's associated risks. By evading these risks, they also open up treatment options to patients who otherwise are poor surgical candidates. Radiosurgery is one of the most intensively studied of these alternatives and has found a growing role in the treatment of medial temporal lobe epilepsy. Copyright © 2016 Elsevier Inc.

  5. Temporally resolved refractive index structure parameter measurement

    Science.gov (United States)

    Henriksson, Markus; Forsling, Robin

    2017-09-01

    The refractive index structure parameter is the most common measure of optical turbulence. It is defined as a statistical quantity for the Kolmogorov spectrum energy cascade of turbulent eddies of different sizes. As such it is formally assumed to be constant in time and space. However, the large scale variation with the diurnal cycle, with altitude or with terrain characteristics is well known. The ensemble average in the definition of the refractive index structure parameter is thus assumed to be applied over a restricted region in space and time. The question of how large volume is needed to determine the refractive index structure parameter and on how short temporal scales it can vary has not received significant attention. To study the temporal variation we have used two independent measurement systems to measure the path-averaged refractive index structure parameter over a 171 m path at 1 m above ground with higher than 1 Hz temporal resolution. One measurement system uses the differential angle-of-arrival of an array of LEDs. The other system measures the scintillation of a single path laser beam using a photon counting system, with time correlation of picosecond pulses for simultaneous measurement of signal and background and with temporal autocorrelation-based variance determination to separate turbulence related scintillations from shot noise. The data shows excellent agreement between the two measurement systems on second level temporal variation, giving confidence in that the measured values show true variation of the refractive index structure parameter. Large scale variation of up to two orders of magnitude can be coupled to solar insolation on this partly cloudy day. High frequency variations that are consistent between the systems used show factor two changes at time scales below one second.

    Full Text Available Este trabalho, subdividido em três partes, apresentou breve histórico da cirurgia cardíaca, com ênfase a cirurgia valvar e substitutos valvulares, empregados com sucesso na década de 60, inicialmente com próteses mecânicas, seguidas pelas heterólogas após a introdução do glutaraldeído para preservação dos tecidos biológicos. As indicações básicas para operar lesões valvares consistem em alívio dos sintomas, prevenção das complicações e da mortalidade. Foram descritos, também, na primeira parte da publicação, aspectos da indicação cirúrgica, com ênfase em estenose e insuficiência das valvas mitral, aórtica, tricúspide e pulmonar, endocardite infecciosa ativa e da conduta pré-operatória, além da caracterização das diferentes próteses valvulares cardíacas mecânicas e biológicas existentes no mercado e suas complicações mais freqüentes. O tratamento cirúrgico das valvopatias, incluindo técnica operatória para troca de valvas mitral, aórtica, tricúspide e pulmonar, condutas anestésica e pós-operatória e reoperações foram abordados na segunda parte da publicação. O trabalho foi concluído considerando as situações especiais, como tratamento cirúrgico na endocardite em valvas mitral, tricúspide e aórtica, cuja incidência é maior que na mitral e a causa mais comum de insuficiência aórtica aguda. O desenvolvimento da endocardite tem fisiopatologia diferente quando comparado às próteses e valvas naturais, com morbi-mortalidade maior que a observada nas valvas nativas. Existem fatores que aumentam o risco de endocardite em valva nativa, raça negra, próteses mecânicas, sexo masculino e longo tempo de circulação extracorpórea. A interação clínico-cirúrgica parece influenciar de forma decisiva na obtenção de melhores resultados para essa lesão. Finalmente, foi registrada a nossa experiência com próteses biológicas em posição mitral e aórtica com 11 e 10 anos de seguimento

    Full Text Available A análise da variabilidade espacial e da variabilidade temporal de atributos naturais vem recebendo destaque nos últimos tempos, devido à possibilidade de se realizar estimativas com maior precisão, destacando-se entre esses atributos a precipitação pluviométrica. Objetivou-se com este trabalho estudar o comportamento temporal das chuvas mensais na Estação Climatológica de Uberaba - MG, utilizando-se a série das precipitações pluviais mensais e anuais de 1914 a 2000. Os dados referentes à Estação Climatológica de Uberaba - Estação Experimental Getúlio Vargas - foram obtidos no Laboratório de Climatologia e Recursos Hídricos do Instituto de Geografia - Universidade Federal de Uberlândia. Realizou-se análise exploratória dos dados por meio de algumas estatísticas, como média aritmética, desvio-padrão, valores máximos e valores mínimos e histogramas. A análise de variabilidade temporal foi feita por meio de semivariâncias. Verificou-se uma tendência à normalidade nos meses correspondentes ao período de outubro a março e assimetria no período de abril a setembro. Observou-se a presença do efeito pepita puro, não constatando-se dependência temporal e, conseqüentemente, estudos e inferências estatísticas podem ser realizados com base em métodos da estatística não espacial.The purpose of this work was to verify the temporal dependence of monthly rainfall in the climatological station of Uberaba-MG, Brazil, using geostatistical methods.

    The research projects on epilepsy addressed two main issues: the pathophysiology of the inter-ictal hypo-metabolism in temporal lobe epilepsy and the role of the basal ganglia in the control of seizure. Our research projects focused primarily on temporal lobe epilepsy: The pathophysiology of inter-ictal hypo-metabolism and its correlation with the epileptogenic network was investigated in patients with mesial temporal lobe epilepsy. Inter-ictal hypo-metabolism is commonly found in mesio-temporal lobe epilepsy (MTLE) but its pathophysiology remains incompletely understood. We hypothesized that metabolic changes reflect the preferential networks involved in ictal discharges. We analyzed the topography of inter-ictal hypo-metabolism according to electro-clinical patterns in 50 patients with unilateral hippocampal sclerosis (HS) and consistent features of MTLE. Based on electro-clinical correlations we identified 4 groups:1) mesial group characterized by mesial seizure onset without evidence of early spread beyond the temporal lobe; 2) anterior mesio-lateral group (AML) with early anterior spread, involving the anterior lateral temporal cortex and insulo-fronto-opercular areas; 3) widespread mesio-lateral group (WML) with widespread spread, involving both anterior and posterior lateral temporal and peri-sylvian areas; 4) bi-temporal group (BT) with early contralateral temporal spread. Results of FDG-PET imaging in each group were compared to control subjects using statistical parametric mapping software (SPM99). MRI data and surgical outcome in each group were compared to metabolic findings. Hypo-metabolism was limited to the hippocampal gyrus, the temporal pole and the insula in the mesial group. Gradual involvement of the lateral temporal cortex, the insula and the peri-sylvian areas was observed in the AML and WML groups. The BT group differed from the others by mild bi-temporal involvement, bilateral insular hypo-metabolism and longer epilepsy duration. MRI

    Full Text Available Auditory recognition memory in non-human primates differs from recognition memory in other sensory systems. Monkeys learn the rule for visual and tactile delayed matching-to-sample within a few sessions, and then show one-trial recognition memory lasting 10-20 minutes. In contrast, monkeys require hundreds of sessions to master the rule for auditory recognition, and then show retention lasting no longer than 30-40 seconds. Moreover, unlike the severe effects of rhinal lesions on visual memory, such lesions have no effect on the monkeys’ auditory memory performance. It is possible, therefore, that the anatomical pathways differ. Long-term visual recognition memory requires anatomical connections from the visual association area TE with areas 35 and 36 of the perirhinal cortex (PRC. We examined whether there is a similar anatomical route for auditory processing, or that poor auditory recognition memory may reflect the lack of such a pathway. Our hypothesis is that an auditory pathway for recognition memory originates in the higher order processing areas of the rostral superior temporal gyrus (rSTG, and then connects via the dorsolateral temporal pole to access the rhinal cortex of the medial temporal lobe. To test this, we placed retrograde (3% FB and 2% DY and anterograde (10% BDA 10,000 MW tracer injections in rSTG and the dorsolateral area 38DL of the temporal pole. Results showed that area 38DL receives dense projections from auditory association areas Ts1, TAa, TPO of the rSTG, from the rostral parabelt and, to a lesser extent, from areas Ts2-3 and PGa. In turn, area 38DL projects densely to area 35 of PRC, entorhinal cortex, and to areas TH/TF of the posterior parahippocampal cortex. Significantly, this projection avoids most of area 36r/c of PRC. This anatomical arrangement may contribute to our understanding of the poor auditory memory of rhesus monkeys.

    Full Text Available This study aims to acknowledge the teaching work of/in the Specialized Educational Service (SES in the public education system of the state of Santa Catarina, Brazil, through the voices of teachers who work in the area. Data were collected by questionnaires from approximately 34 Kindergarten and Elementary School teachers. All the participants were women between 31 and 50 years old selected through public tender, and who work a 40-hour week journey in the Specialized Education Service. These teachers are experienced in the field - 71% have been teaching for over six years in the municipal education; however, 88% of them have been working in the SES for three years or less and are, therefore, undergoing a professional moment of discovery and survival. Considering that these teachers are in a (recognition moment in the SES, their work is still singly configured. Nevertheless, some of the teachers perform activities that involve the whole school community. Participants’ voices revealed a lack of cohesion of teachers in the SES. There is need to discuss about this issue in order to try to understand their role, and even signify the SES as a pedagogical strategy in the school context, by contributing to the schooling process students, who are, first of all, school students. O estudo teve por objetivo conhecer o trabalho docente do/no Atendimento Educacional Especializado (AEE em uma rede municipal de ensino do Estado de Santa Catarina, Brasil, pelas vozes das professoras que atuam nesse serviço. Para a construção dos dados, aplicaram?se questionários a 34 professoras atuantes na Educação Infantil e no Ensino Fundamental, que foram tratados à luz da análise de conteúdo. Todas as participantes da pesquisa são mulheres com idades entre 31 e 50 anos concursadas como docentes no AEE, atuando 40 horas semanais como docentes no AEE. Pode-se dizer que as professoras especializadas são experientes, já que 71% atuam há mais de seis anos na rede

    Full Text Available Surgery of temporal lobe epilepsy is the best opportunity for seizure freedom in medically intractable patients. The surgical approach has evolved to recognize the paramount importance of the mesial temporal structures in the majority of patients with temporal lobe epilepsy who have a seizure origin in the mesial temporal structures. For those individuals with medically intractable mesial temporal lobe epilepsy, a selective amygdalohippocampectomy surgery can be done that provides an excellent opportunity for seizure freedom and limits the resection to temporal lobe structures primarily involved in seizure genesis.

    A common but an important feature of all real-world networks is that they are temporal in nature, i.e., the network structure changes over time. Due to this dynamic nature, it becomes difficult to propose suitable growth models that can explain the various important characteristic properties of these networks. In fact, in many application oriented studies only knowing these properties is sufficient. For instance, if one wishes to launch a targeted attack on a network, this can be done even without the knowledge of the full network structure; rather an estimate of some of the properties is sufficient enough to launch the attack. We, in this paper show that even if the network structure at a future time point is not available one can still manage to estimate its properties. We propose a novel method to map a temporal network to a set of time series instances, analyze them and using a standard forecast model of time series, try to predict the properties of a temporal network at a later time instance. To our aim, we consider eight properties such as number of active nodes, average degree, clustering coefficient etc. and apply our prediction framework on them. We mainly focus on the temporal network of human face-to-face contacts and observe that it represents a stochastic process with memory that can be modeled as Auto-Regressive-Integrated-Moving-Average (ARIMA). We use cross validation techniques to find the percentage accuracy of our predictions. An important observation is that the frequency domain properties of the time series obtained from spectrogram analysis could be used to refine the prediction framework by identifying beforehand the cases where the error in prediction is likely to be high. This leads to an improvement of 7.96% (for error level ≤20%) in prediction accuracy on an average across all datasets. As an application we show how such prediction scheme can be used to launch targeted attacks on temporal networks. Contribution to the Topical Issue

    The standard measure of the intensity of a tornado is the Enhanced Fujita scale, which is based qualitatively on the damage caused by a tornado. An alternative measure of tornado intensity is the tornado path length, L. Here we examine the spatial-temporal clustering of severe tornadoes, which we define as having path lengths L ≥ 10 km. Of particular concern are tornado outbreaks, when a large number of severe tornadoes occur in a day in a restricted region. We apply a spatial-temporal clustering analysis developed for earthquakes. We take all pairs of severe tornadoes in observed and modelled outbreaks, and for each pair plot the spatial lag (distance between touchdown points) against the temporal lag (time between touchdown points). We apply our spatial-temporal lag methodology to the intense tornado outbreaks in the central United States on 26 and 27 April 2011, which resulted in over 300 fatalities and produced 109 severe (L ≥ 10 km) tornadoes. The patterns of spatial-temporal lag correlations that we obtain for the 2 days are strikingly different. On 26 April 2011, there were 45 severe tornadoes and our clustering analysis is dominated by a complex sequence of linear features. We associate the linear patterns with the tornadoes generated in either a single cell thunderstorm or a closely spaced cluster of single cell thunderstorms moving at a near-constant velocity. Our study of a derecho tornado outbreak of six severe tornadoes on 4 April 2011 along with modelled outbreak scenarios confirms this association. On 27 April 2011, there were 64 severe tornadoes and our clustering analysis is predominantly random with virtually no embedded linear patterns. We associate this pattern with a large number of interacting supercell thunderstorms generating tornadoes randomly in space and time. In order to better understand these associations, we also applied our approach to the Great Plains tornado outbreak of 3 May 1999. Careful studies by others have associated

    Full Text Available Moralidade e conhecimento são desenvolvidos através de um processo interno de construção e estão estreitamente relacionados, como estudado por Piaget (1994. As implicações pedagógicas da teoria piagetiana nos dois domínios, moral e intelectual, são mostradas por Kamii e DeVries (1991 que desenvolvem, com base nessa teoria, princípios de ensino e objetivos cognitivos e socioemocionais para atividades de conhecimento físico para a pré-escola. Nas atividades de conhecimento físico, as ações da criança sobre o objeto passam por quatro níveis descritos pelas autoras. Gonçalves (1991 cria atividades de conhecimento físico para as primeiras séries do ensino fundamental, fazendo a extensão dos princípios de ensino e dos objetivos cognitivos de Kamii e DeVries para essas séries, e verifica que o nível das explicações causais, que não é alcançado na pré-escola, é atingido nas primeiras séries. Os objetivos socioemocionais definidos por Kamii e DeVries dizem respeito às relações da criança com o adulto e com seus iguais, e compreendem o desenvolvimento da autonomia, cooperação e iniciativa, considerando que, à luz do construtivismo de Piaget, essas características são necessárias para que a construção ocorra. Nesse contexto, desde que a proposta de Gonçalves focaliza o domínio cognitivo, buscamos investigar o potencial das atividades de conhecimento físico também para o desenvolvimento socioemocional nas séries iniciais.

    Full Text Available OBJETIVO: Descrever o padrão de distribuição das oclusopatias em adolescentes brasileiros e identificar fatores associados a esse agravo bucal. MÉTODOS: Foram analisados dados de 7.328 e 5.445 adolescentes de 12 e 15-19 anos, respectivamente, participantes da Pesquisa Nacional de Saúde Bucal (SBBrasil 2010. O desfecho foi oclusopatia muito grave segundo o índice de estética dental. As variáveis de exposição foram sexo, cor da pele, renda familiar mensal, número de bens, aglomeração no domicílio, cárie não tratada, perda dentária, uso, frequência e motivo da consulta odontológica. Foram conduzidas análises de regressão logística considerando a complexidade do desenho amostral, com base em modelo hierarquizado. RESULTADOS: Prevalência de oclusopatia muito grave foi observada em 6,5% e 9,1% nos jovens de 12 e 15-19 anos, respectivamente. Após análise ajustada, a chance do desfecho foi 1,59 (IC95% 1,08;2,34 vez maior nos pardos e pretos em relação aos brancos e 2,66 (IC95% 1,26;5,63 vezes maior dentre aqueles com perda de pelo menos um primeiro molar aos 12 anos. Jovens de 15-19 anos cuja renda familiar mensal foi de até R$ 1.500,00 (OR 2,69 [IC95% 1,62;4,47] e aqueles que consultaram o dentista para tratamento (OR 2,59 [IC95% 2,55;4,34] apresentaram maior chance de oclusopatia muito grave quando comparados aos de maior renda e que procuraram o dentista para prevenção. CONCLUSÕES: A distribuição das oclusopatias em adolescentes brasileiros segue o padrão de iniquidade social de outros agravos à saúde. Essas informações são úteis para a formulação de critérios relacionados tanto com a distribuição e provisão de recursos quanto com as prioridades de tratamento ortodôntico fundamentados no princípio da equidade da atenção à saúde bucal.

    Full Text Available Desde o início dos tempos o ser humano teve necessidade de transformar a natureza, afastandose de sua forma natural de organização. Atualmente, a necessidade do contato direto permanece, mesmo com a grande distância imposta pela criação das cidades, porque faz parte da condição humana. Os jardins foram inventados pelo homem para realizar esta relação, ficando a meio caminho entre a beleza espontânea das formas naturais e o ato de ordenação e simplificação da realidade que requer a percepção humana. Eles são a expressão arquitetônica do homem pelos elementos naturais. Este trabalho objetiva estudar as formas vegetais e compreendê-las como instrumentos de produção da arquitetura, simulando diferentes situações de projeto relacionadas à composição da paisagem. Para estudo e aplicação de uma metodologia de projeto foi desenvolvido como estudo de caso a proposta de um jardim botânico para a cidade de Florianópolis/SC. A idéia de projetar um jardim botânico surgiu ao se pensar que este espaço possibilita não só o contato dos seres humanos com a natureza por meio do lazer, mas também pela ciência, sendo necessária a criação de ambientes formados por grupos vegetais específicos, aumentando a diversidade de situações projetuais. Primeiramente foram definidas e estudadas formas de composição vegetal em relação a elementos isolados e conjuntos, associando a utilização da vegetação à percepção que se deseja que as pessoas tenham de cada espaço determinado de forma genérica. Pela aplicação dos parâmetros compositivos foram simuladas diferentes situações de projeto por meio de croquis, criando os ambientes desejados e definindo a partir daí as espécies vegetais que se adequassem melhor à composição escolhida. Para escolher as espécies foram criados parâmetros de classificação relacionados a características formais, funcionais e temporais de cada elemento

    Full Text Available The functional significance of MRI-defined mesial temporal sclerosis in temporal lobe epilepsy (TLE is not completely established. In order to study the possible relationship between signals of mesial temporal sclerosis on MRI and interictal SPECT findings we selected 18 patients with complex partial seizures, unilateral temporal EEG focus and normal CT. The EEG focus was defined by the presence of interictal sharp waves and slow background on several scalp EEG obtained during many years of follow up in all patients and by ictal recordings with sphenoidal electrodes in 12 patients. Group I comprised patients (n=11 in whom MRI showed mesial temporal sclerosis; group II patients (n=7 had normal MRIs. All patients were submitted to interictal 99m-Tc HMPAO injections with concomitant EEG monitoring. Lateralized hypoperfusion ipsilateral to the EEG was found in 13 patients (72%. In all Group II and in 6 Group I patients a temporal hypoperfusion was found. This SPECT study showed a higher positivity rate in patients with normal MRI than previously reported. On the other hand, in all these group II patients a neocortical origin of epileptic focus was suspected on clinical or electroencephalographic basis. Positive SPECT findings may be at least as prevalent in neocortical as in mesiolimbic epilepsy.

    We retrospectively analyzed 8 patients with intractable medial temporal lobe epilepsy (MTLE) who underwent the anterior temporal lobectomy with hippocampectomy (ATL) without invasive examinations such as chronic subdural electrode recording. Five patients had a history of febrile convulsion. While all 8 patients had oral automatism, automatism of ipsilateral limbs with dystonic posture of contralateral limbs was demonstrated in 2 patients. Bilateral temporal paroxysmal activities on interictal EEG was observed in 4 patients and all patients had clear ictal onset zone on unilateral anterior temporal region. MRI demonstrated unilateral hippocampal sclerosis in 5 cases. Interictal FDG-PET depicted hypometabolism of the unilateral temporal lobe in all cases, however, ECD-SPECT failed to reveal the hypoperfusion of the unilateral temporal lobe in a case. Postoperatively, 7 cases became seizure free, and one had rare seizure. Non-invasive examinations, especially ictal EEG and concordant FDG-PET findings, in patients with oral automatism in seizure semiology, successfully select patients with MTLE for ATL. (author)

    Music in Dementia Assessment Scales (MiDAS), an observational outcome measure for music therapy with people with moderate to severe dementia, was developed from qualitative data of focus groups and interviews. Expert and peer consultations were conducted at each stage of the scale development to maximize its content validity. This study aimed to evaluate the psychometric properties of MiDAS. Care home residents with dementia attended weekly group music therapy for up to ten sessions. Music therapists and care home staff were requested to complete weekly MiDAS ratings. The Quality of Life Scale (QoL-AD) was completed at three time-points. A total of 629 (staff = 306, therapist = 323) MiDAS forms were completed. The statistical analysis revealed that MiDAS has high therapist inter-rater reliability, low staff inter-rater reliability, adequate staff test-retest reliability, adequate concurrent validity, and good construct validity. High factor loadings between the five MiDAS Visual Analogue Scale (VAS) items, levels of Interest, Response, Initiation, Involvement, and Enjoyment, were found. This study indicates that MiDAS has good psychometric properties despite the small sample size. Future research with a larger sample size could provide a more in-depth psychometric evaluation, including further exploration of the underlying factors. MiDAS provides a measure of engagement with musical experience and offers insight into who is likely to benefit on other outcomes such as quality of life or reduction in psychiatric symptoms.

    Full Text Available Neste artigo, investiga-se a dinâmica do processo decisório conduzido por grupos de trabalho ao longo do tempo em ambientes com diferentes latitudes de ação (graus de liberdade para a atuação dos gestores distintos. O objetivo é verificar a influência do tempo e do ambiente nos processos decisórios em grupo. O tema é enfocado a partir de uma revisão teórica considerando três tópicos - o processo decisório conduzido por grupos, a influência do tempo nesses processos e a influência do ambiente nesses processos -, os quais dão origem às hipóteses a serem testadas. Na pesquisa de campo, de natureza quantitativa, utiliza-se o método survey e os dados foram coletados com 89 grupos da disciplina Jogos de Empresa, em um curso de graduação em Administração de Empresas. Para o tratamento dos dados, utilizou-se a modelagem por equações estruturais via partial least square para avaliação das relações entre os construtos. Como resultado, constatou-se influência temporal na associação entre qualidade do processo decisório e resultados organizacionais, reduzindo-se o efeito do perfil dos grupos. Já as relações interpessoais, independente do ambiente, influenciaram nos processos de planejamento e execução das decisões. Concluiu-se que diferentes relações entre perfil dos gestores, qualidade do processo e resultados são observadas pela incorporação simultânea das dimensões temporal e ambiental como contingências na análise do processo decisório em grupo.

    This paper focuses on temporal constraint problems where the objective is to optimize a set of local preferences for when events occur. In previous work, a subclass of these problems has been formalized as a generalization of Temporal CSPs, and a tractable strategy for optimization has been proposed, where global optimality is defined as maximizing the minimum of the component preference values. This criterion for optimality, which we call 'Weakest Link Optimization' (WLO), is known to have limited practical usefulness because solutions are compared only on the basis of their worst value; thus, there is no requirement to improve the other values. To address this limitation, we introduce a new algorithm that re-applies WLO iteratively in a way that leads to improvement of all the values. We show the value of this strategy by proving that, with suitable preference functions, the resulting solutions are Pareto Optimal.

    2006-01-01

    Statistical Methods for Spatio-Temporal Systems presents current statistical research issues on spatio-temporal data modeling and will promote advances in research and a greater understanding between the mechanistic and the statistical modeling communities.Contributed by leading researchers in the field, each self-contained chapter starts with an introduction of the topic and progresses to recent research results. Presenting specific examples of epidemic data of bovine tuberculosis, gastroenteric disease, and the U.K. foot-and-mouth outbreak, the first chapter uses stochastic models, such as point process models, to provide the probabilistic backbone that facilitates statistical inference from data. The next chapter discusses the critical issue of modeling random growth objects in diverse biological systems, such as bacteria colonies, tumors, and plant populations. The subsequent chapter examines data transformation tools using examples from ecology and air quality data, followed by a chapter on space-time co...

  12. Perceived luminance depends on temporal context.

    Science.gov (United States)

    Eagleman, David M; Jacobson, John E; Sejnowski, Terrence J

    2004-04-22

    Brightness--the perception of an object's luminance--arises from complex and poorly understood interactions at several levels of processing. It is well known that the brightness of an object depends on its spatial context, which can include perceptual organization, scene interpretation, three-dimensional interpretation, shadows, and other high-level percepts. Here we present a new class of illusion in which temporal relations with spatially neighbouring objects can modulate a target object's brightness. When compared with a nearby patch of constant luminance, a brief flash appears brighter with increasing onset asynchrony. Simultaneous contrast, retinal effects, masking, apparent motion and attentional effects cannot account for this illusory enhancement of brightness. This temporal context effect indicates that two parallel streams--one adapting and one non-adapting--encode brightness in the visual cortex.

    The power of any kind of network approach lies in the ability to simplify a complex system so that one can better understand its function as a whole. Sometimes it is beneficial, however, to include more information than in a simple graph of only nodes and links. Adding information about times of interactions can make predictions and mechanistic understanding more accurate. The drawback, however, is that there are not so many methods available, partly because temporal networks is a relatively young field, partly because it is more difficult to develop such methods compared to for static networks. In this colloquium, we review the methods to analyze and model temporal networks and processes taking place on them, focusing mainly on the last three years. This includes the spreading of infectious disease, opinions, rumors, in social networks; information packets in computer networks; various types of signaling in biology, and more. We also discuss future directions.

    2004-10-01

    Music genre provides an efficient way to index songs in the music database, and can be used as an effective means to retrieval music of a similar type, i.e. content-based music retrieval. In addition to other features, the temporal domain features of a music signal are exploited so as to increase the classification rate in this research. Three temporal techniques are examined in depth. First, the hidden Markov model (HMM) is used to emulate the time-varying properties of music signals. Second, to further increase the classification rate, we propose another feature set that focuses on the residual part of music signals. Third, the overall classification rate is enhanced by classifying smaller segments from a test material individually and making decision via majority voting. Experimental results are given to demonstrate the performance of the proposed techniques.

    1991-01-01

    Basal meningoencephaloceles represent a rare entity, and they may be associated with a variety of midline cerebral abnormalities. The classification of basal meningoencephaloceles is related to their anatomic location. This paper reports experience in 3 patients, 2 who have temporal lobe epilepsy and a bone defect in the region of the foramen rotondum. In these 2 patients the encephalocele and its covering were protruding into the pterygopalatine fossa without any orbital involvement. The third patient presented with cerebrospinal fluid rhinorrhea caused by a transsphenoidal meningoencephalocele. MR imaging is the examination of choice for detecting these lesions since it allows for the visualization of the encephalocele and its meningeal covering as well as the bone defect and associated lesions in the temporal lobes

    This article discusses the requirements of a formal specification for the annotation of temporal information in clinical narratives. We discuss the implementation and extension of ISO-TimeML for annotating a corpus of clinical notes, known as the THYME corpus. To reflect the information task and the heavily inference-based reasoning demands in the domain, a new annotation guideline has been developed, “the THYME Guidelines to ISO-TimeML (THYME-TimeML)”. To clarify what relations merit annotation, we distinguish between linguistically-derived and inferentially-derived temporal orderings in the text. We also apply a top performing TempEval 2013 system against this new resource to measure the difficulty of adapting systems to the clinical domain. The corpus is available to the community and has been proposed for use in a SemEval 2015 task. PMID:29082229

    Full Text Available Heidegger’s thinking about poetic dwelling and Derrida’s impressions of Freudian estrangement are employed to provide a constitutional analysis of the experience of Japanese architecture, in particular, the Japanese vestibule (genkan. This analysis is supplemented by writings by Japanese architects and poets. The principal elements of Japanese architecture are: (1 ma, and (2 en. Ma is usually translated as ‘interval’ because, like the English word, it applies to both space and time.  However, in Japanese thinking, it is not so much an either/or, but rather a both/and. In other words, Japanese architecture emphasises the temporal aspect of dwelling in a way that Western architectural thinking usually does not. En means ‘joint, edge, the in-between’ as an ambiguous, often asymmetrical spanning of interior and exterior, rather than a demarcation of these regions. Both elements are aimed at producing an experience of temporality and transiency.

    Real social contacts are often intermittent such that a link between a pair of nodes in a social network is only temporarily used. The effects of such temporal networks on social dynamics have been investigated for several phenomenological models such as epidemic spreading, linear diffusion processes, and nonlinear oscillations. Here, we numerically investigate nonlinear social balance dynamics in such a situation. Social balance is a classical psychological theory, which dictates that a triad is balanced if the three agents are mutual friends or if the two of them are the friends of each other and hostile to the other agent. We show that the social balance dynamics is slowed down on the temporal complete graph as compared to the corresponding static complete graph.

    People often prefer inferior options in the present even when options in the future are more lucrative. Five studies investigated whether decision making could be improved by manipulating construal level and psychological distance. In Studies 1a, 1b, and 2, temporal discounting was reduced when future rewards (trips to Paris) were construed at a relatively concrete level, thus inducing a similar level of construal to present rewards. By contrast, Studies 3 and 4 reduced temporal discounting by making present financial rewards more psychologically distant via a social proximity manipulation, and thus linked to a similar high level of construal as future rewards. These results suggest that people prefer the more lucrative option when comparing two intertemporal choices that are construed on a similar level instead of on a different level. Thus, changes in construal level and mental representations can be used to promote more desirable choices in economic decision making.

    2002-06-01

    Full Text Available Many algorithms for temporal video partitioning rely on the analysis of uncompressed video features. Since the information relevant to the partitioning process can be extracted directly from the MPEG compressed stream, higher efficiency can be achieved utilizing information from the MPEG compressed domain. This paper introduces a real-time algorithm for scene change detection that analyses the statistics of the macroblock features extracted directly from the MPEG stream. A method for extraction of the continuous frame difference that transforms the 3D video stream into a 1D curve is presented. This transform is then further employed to extract temporal units within the analysed video sequence. Results of computer simulations are reported.

Este artigo procura recuperar a memória desse período, basicamente sob três ângulos: técnicooperacional, acadêmico e legal. Em termos operacionais, a primeira empresa de Auditoria Independente a se estabelecer no Brasil foi a DeloitteToucheTohmatsu, que instalou seu primeiro escritório no Rio de Janeiro, em 1911, e o segundo em Recife, em 1917. Àquela época, o país estava longe de ter qualquer tipo de preocupação com o assunto. Um dos primeiros artigos sobre esse tema foi publicado, em 1928, pela Revista Paulista de Contabilidade, com o título "Contabilidade na Grã-bretanha". O primeiro livro sobre Auditoria foi publicado apenas em 1957 e denominado "Curso de Auditoria". No que se refere ao aspecto legal, os conceitos e técnicas de auditoria foram formalmente introduzidos no ensino universitário por força do Decreto-Lei 7.988, de 22 de dezembro de 1945, o qual regulamentava a educação superior nos cursos de Economia, Contabilidade e Ciências Atuariais. Ainda no âmbito das leis, somente em 1965, pela primeira vez, foi introduzida afigura do Auditor Independente em um diploma legal. Esse foi um marco de enorme importância para a evolução da profissão e das práticas contábeis. Desde então, tanto as práticas de Auditoria quanto seu ensino acadêmico se consolidaram no país, de forma a atender seu principal objetivo: opinar a respeito da adequação das demonstrações contábeis publicadas, no que diz respeito aos seus aspectos mais relevantes.It is hard to determine the exact date of the first auditing work in Brazil but, about one century ago, the balance sheet

    Synonyms for the `battered child` syndrome (BCS) are terms describing the physical and body aspects of the process, such as `child abuse`, or `non-accidental injury`. These are to be distinguished from the psychic aspects and abuse, emotional and bodily neglect, and sexual abuse. Most cases are one or another combination of these aspects. Radiology is the essential method for giving proof of such abuses, identifying the signs of maltreatment in a medical record, or for disproving suspected abuse. (orig./AJ) [Deutsch] Als Synonym fuer das `Battered-Child`-Syndrom (BCS) stehen die Begriffe der koerperlichen-/physikalischen-Kindesmisshandlung, im angelsaechsischen Sprachraum die Begriffe `Child Abuse` und `Nonaccidental Injury`. Vom Syndrom abzugrenzen sind die seelische Misshandlung, die seelische und koerperliche Vernachlaessigung, und der sexuelle Missbrauch. Kombinationsformen sind nicht selten. Bei der Diagnostik des Syndroms spielt die Radiologie eine entscheidende Rolle. So hilft der Einsatz adaequater Untersuchungsmethoden, den Tatbestand der Misshandlung zu identifizieren und zu dokumentieren, aber auch einen Verdacht zu widerlegen. (orig./AJ)

The biggest tax gaps are not due to „simple“ tax fraud, but to tax evasion which in a globalized and „dematerialized“ world of economic activities taking place in the cloud is hardly detected by tax administrations. This lack of efficiency in the enforcement of tax law is not only based on the lack of State ́s resources but also on the fact that the instruments of enforcement have been adapted little to the changements in the way economic activities are effectuated. Concepts of good governance could offer new ideas for improving the enforcement rules. DEUTSCH: Eine gleichmäßige Besteuerung sicherzustellen fällt den Staaten heutzutage nicht leicht. Die größten Steuerausfälle werden nach überwiegender Auffassung nicht mehr durch einfache Steuerhinterziehungen, sondern durch Steuerumgehungen bewirkt, die in einer globalisierten und „entmaterialisierten“ (weil in der „Cloud“ stattfindenden Wirtschaftswelt vielfach vom Staat unentdeckt möglich sind. Die Vollzugsineffizienz liegt nicht nur an knappen staatlichen Ressourcen zur Sicherstellung der Kontrolle, sondern auch am Vollzugsinstrumentarium, das den geänderten Verhältnissen wirtschaftlicher Aktivitäten wenig angepasst wurde. Governance-Aspekte könnten Lösungsansätze bieten.

    Full Text Available A definição da resposta espectral da cultura do café é uma das etapas na identificação de lavouras cafeeiras em imagens de satélites de sensoriamento remoto, para fins de mapeamento e estimativa de área plantada. O objetivo deste trabalho foi avaliar o potencial das imagens adquiridas pelos satélites da série Landsat, no mapeamento da cultura do café para a previsão de safras. Foi feita uma análise temporal do comportamento espectral de lavouras de café-formação e café-produção por meio de imagens livres de nuvens adquiridas nos anos de 1999 e 2001. Também foi analisado o comportamento espectral das classes pastagem e mata, que compõem os alvos de maior ocupação na área de estudo. As imagens do período seco foram mais eficientes no mapeamento de lavouras de café-formação e café-produção. As imagens da banda 4 dos dois sensores apresentaram melhor diferenciação espectral entre café e os demais alvos da cena. A reflectância do café-produção apresentou grande variabilidade entre lavouras, que pode ser atribuída à idade, espaçamento de plantas, cultivar, indicando a necessidade de trabalho em campo para a correta identificação das lavouras de café nas imagens Landsat.The definition of the spectral response of coffee crop is one of the steps to identify coffee fields in remote sensing images in order to map and estimate planted area. The objective of this work was to analyze the potential of the images acquired by the Landsat series satellites, for coffee crop mapping and forecast. A temporal analysis of the spectral behavior of coffee crop fields under development and under active production was performed through cloud free images acquired in the years of 1999 and 2001. The spectral behavior of pasture and forest was also analyzed due to their relevance in the study area. The results showed that images acquired during the dry season were more efficient to map coffee crop at early development and under

    With the ongoing crisis of biodiversity loss and limited resources for conservation, the concept of biodiversity hotspots has been useful in determining conservation priority areas. However, there has been limited research into how temporal variability in biodiversity may influence conservation area prioritization. To address this information gap, we present an approach to evaluate the temporal consistency of biodiversity hotspots in large marine ecosystems. Using a large scale, public monitoring dataset collected over an eight year period off the US Pacific Coast, we developed a methodological approach for avoiding biases associated with hotspot delineation. We aggregated benthic fish species data from research trawls and calculated mean hotspot thresholds for fish species richness and Shannon’s diversity indices over the eight year dataset. We used a spatial frequency distribution method to assign hotspot designations to the grid cells annually. We found no areas containing consistently high biodiversity through the entire study period based on the mean thresholds, and no grid cell was designated as a hotspot for greater than 50% of the time-series. To test if our approach was sensitive to sampling effort and the geographic extent of the survey, we followed a similar routine for the northern region of the survey area. Our finding of low consistency in benthic fish biodiversity hotspots over time was upheld, regardless of biodiversity metric used, whether thresholds were calculated per year or across all years, or the spatial extent for which we calculated thresholds and identified hotspots. Our results suggest that static measures of benthic fish biodiversity off the US West Coast are insufficient for identification of hotspots and that long-term data are required to appropriately identify patterns of high temporal variability in biodiversity for these highly mobile taxa. Given that ecological communities are responding to a changing climate and other

    The new DSM-5 diagnostic criteria for autism spectrum disorders (ASDs) include sensory disturbances in addition to the well-established language, communication, and social deficits. One sensory disturbance seen in ASD is an impaired ability to integrate multisensory information into a unified percept. This may arise from an underlying impairment in which individuals with ASD have difficulty perceiving the temporal relationship between cross-modal inputs, an important cue for multisensory inte...

    The debate regarding the role of ventral occipito-temporal cortex (vOTC) in visual word recognition arises in part from difficulty delineating the functional contributions of vOTC as separate from other areas of the reading network. Successful transcranial magnetic stimulation (TMS) of the area could provide a novel source of information regarding the area’s function, by offering the possibility of temporarily, non-invasively perturbing its information processing and assessing the consequence...

    Many hypotheses have been put forth to explain the origin and early radiation of dinosaurs, but poor age constraints for constituent fossil assemblages make these scenarios difficult to test. Using precise radioisotopic ages, we demonstrate that the temporal gap between assemblages containing only dinosaur precursors and those with the first dinosaurs was 5–10 million years shorter than previously thought. Thus, these data suggest that the origin of dinosaurs was a relatively rapid evolutiona...

    In the last decade, models of rational choice have chimed into the discussion on racial profiling, the use of race in stop and search decisions of the police. The models describe the behavior of motorists and the police and provide empirical tests to assess the question whether the police exhibit racial animus. However, existing studies have neglected the effect of spatial and temporal aggregation of the data on the application of the tests. Using data from the Florida Highway Patrol, this pa...

    Full Text Available No sudeste do Brasil, principalmente no Estado de Minas Gerais, são observados planaltos escalonados drenados por diferentes bacias hidrográficas, muitas vezes separadas entre si por nítidos degraus morfológicos resultantes da diferença no potencial erosivo de suas cabeceiras de drenagem, como resposta à tectônica distensiva cenozoica. Adicionalmente, capturas fluviais que condicionam a rede de drenagem a buscar um novo perfil de equilíbrio e alteram a morfologia dos canais envolvidos (captor, capturado, decaptado e afluentes diretos são frequentes. Esse artigo apresenta o papel de três grandes capturas fluviais (Capturas de São Vicente de Paula, de Carandaí e de Vilas-Boas na morfodinâmica de três bordas interplanálticas entre as quatro mais importantes bacias hidrográficas do sudeste do Brasil: são Francisco, Doce, Paraná e Paraíba do Sul.  A análise inicial com base em material cartográfico (cartas topográficas, geológicas e geomorfológicas e os trabalhos de campo, com descrição dos canais envolvidos mostraram que as três capturas analisadas apresentam características diferentes: 1 em Vilas-Boas a crista da escarpa se encontra na posição original e as alterações na paisagem se limitam aos vales, com incisão de 2,5m, até 1 km à montante do ponto de captura; 2 em Carandaí a crista da escarpa já se encontra recuada a cerca de 1,5 km do ponto de captura, que foi rebaixado em100 m, e as alterações atingem os 3 km de distância desse ponto; e 3 em São Vicente a crista da escarpa já se encontra recuada a cerca de 3,5 km do ponto de captura, que foi rebaixado em 250m (atingindo o planalto inferior e as alterações atingem 8km de distância desse ponto.   Estes resultados demonstram a influência das capturas fluviais na morfodinâmica das bordas interplanálticas do sudeste do Brasil.

    To study differences in the whole-brain structural connectomes of patients with left temporal lobe epilepsy (TLE) and healthy control subjects. This study was approved by the institutional review board, and all individuals gave signed informed consent. Sixty-direction diffusion-tensor imaging and magnetization-prepared rapid acquisition gradient-echo (MP-RAGE) magnetic resonance imaging volumes were analyzed in 24 patients with left TLE and in 24 healthy control subjects. MP-RAGE volumes were segmented into 1015 regions of interest (ROIs) spanning the entire brain. Deterministic white matter tractography was performed after voxelwise tensor calculation. Weighted structural connectivity matrices were generated by using the pairwise density of connecting fibers between ROIs. Graph theoretical measures of connectivity networks were compared between groups by using linear models with permutation testing. Patients with TLE had 22%-45% reduced (P < .01) distant connectivity in the medial orbitofrontal cortex, temporal cortex, posterior cingulate cortex, and precuneus, compared with that in healthy subjects. However, local connectivity, as measured by means of network efficiency, was increased by 85%-270% (P < .01) in the medial and lateral frontal cortices, insular cortex, posterior cingulate cortex, precuneus, and occipital cortex in patients with TLE as compared with healthy subjects. This study suggests that TLE involves altered structural connectivity in a network that reaches beyond the temporal lobe, especially in the default mode network.

  17. Temporality and the torments of time.

    Immersion in time gives birth to consciousness, as well as conflict and torment. When human beings developed a sense of future, they also gained the ability to anticipate threats from nature or their fellow beings. They thereby created cultures that are bastions of survival, as well as places of poetry, art and religion where they could band together and reflect upon their common plight. The practice of psychoanalysis is in many ways a temporal process, a process of remembering, for owning and elaborating a past that gives us substance, thereby providing a basis for reflective consciousness. Stimulated by Freud's early writings, Lacan, Laplanche and their successors in particular have focussed extensively on time and psychoanalysis, and their views are a central point of this discussion. A substantial case study is offered that provides concrete examples of these perspectives. A multi-faceted view of temporality emerges, one that is more syncopated than linear or teleological. In conclusion, I will briefly discuss recent findings in the neuroscience of memory and 'time travel' that underpin contemporary psychoanalytic ideas in surprising ways. It is important to remember that acceptance of the contradictory nature of temporal experience can open space for increased freedom and playfulness. © 2015, The Society of Analytical Psychology.

  18. Temporal and Evolving Data Warehouse Design

    2017-01-01

    Full Text Available The data model of the classical data warehouse (formally, dimensional model does not offer comprehensive support for temporal data management. The underlying reason is that it requires consideration of several temporal aspects, which involve various time stamps. Also, transactional systems, which serves as a data source for data warehouse, have the tendency to change themselves due to changing business requirements. The classical dimensional model is deficient in handling changes to transaction sources. This has led to the development of various schemes, including evolution of data and evolution of data model and versioning of dimensional model. These models have their own strengths and limitations, but none fully satisfies the above-stated broad range of aspects, making it difficult to compare the proposed schemes with one another. This paper analyses the schemes that satisfy such challenging aspects faced by a data warehouse and proposes taxonomy for characterizing the existing models to temporal data management in data warehouse. The paper also discusses some open challenges.

  19. Spatio-Temporal Reasoning and Context Awareness

    Science.gov (United States)

    Guesgen, Hans W.; Marsland, Stephen

    Smart homes provide many research challenges, but some of the most interesting ones are in dealing with data that monitors human behaviour and that is inherently both spatial and temporal in nature. This means that context becomes all important: a person lying down in front of the fireplace could be perfectly normal behaviour if it was cold and the fire was on, but otherwise it is unusual. In this example, the context can include temporal resolution on various scales (it is winter and therefore probably cold, it is not nighttime when the person would be expected to be in bed rather than the living room) as well as spatial (the person is lying in front of the fireplace) and extra information such as whether or not the fire is lit. It could also include information about how they reached their current situation: if they went from standing to lying very suddenly there would be rather more cause for concern than if they first knelt down and then lowered themselves onto the floor. Representing all of these different temporal and spatial aspects together is a major challenge for smart home research. In this chapter we will provide an overview of some of the methodologies that can be used to deal with these problems. We will also outline our own research agenda in the Massey University Smart Environments (MUSE) group.

    The distribution of a syndrome in space and time may suggest clues to its etiology. The cause of Kawasaki syndrome, a systemic vasculitis of infants and children, is unknown, but an infectious etiology is suspected. Seasonality and clustering of Kawasaki syndrome cases were studied in Japanese children with Kawasaki syndrome reported in nationwide surveys in Japan. Excluding the years that contained the 3 major nationwide epidemics, 84,829 cases during a 14-year period (1987-2000) were analyzed. To assess seasonality, we calculated mean monthly incidence during the study period for eastern and western Japan and for each of the 47 prefectures. To assess clustering, we compared the number of cases per day (daily incidence) with a simulated distribution (Monte Carlo analysis). Marked spatial and temporal patterns were noted in both the seasonality and deviations from the average number of Kawasaki syndrome cases in Japan. Seasonality was bimodal with peaks in January and June/July and a nadir in October. This pattern was consistent throughout Japan and during the entire 14-year period. Some years produced very high or low numbers of cases, but the overall variability was consistent throughout the entire country. Temporal clustering of Kawasaki syndrome cases was detected with nationwide outbreaks. Kawasaki syndrome has a pronounced seasonality in Japan that is consistent throughout the length of the Japanese archipelago. Temporal clustering of cases combined with marked seasonality suggests an environmental trigger for this clinical syndrome.
