    A Validation Study of the Trio Measure of Visual Processing Ability

    Get PDF
    Trio is a newly developed group-administered instrument designed to measure visual ability for application in cognitive styles research. This study investigated the validity of Trio as seen in its convergence or divergence with two established tests, one conceptually related and one conceptually unrelated. The correlation of Trio scores with scores on these other two tests was examined using a sample of undergraduate students. The analysis of the relationship between scores on Trio and on the conceptually related Learning Figures Test failed to provide evidence that these two tests are measuring the same construct. At the same time, Trio\u27s correlation with the unrelated ACT English section was shown to be fairly low. This second finding supports the conclusion that Trio scores are not severely confounded by verbal ability level

    The Brazilian sardine (Sardinella brasiliensis) and anchoita (Engrautis anchoita) inhabit the southeastern Brazilian Bight. The former spawns at night (21:00-03:00) in coastal region during late-spring and summer, meanwhile, the latter spawns all year-around, mainly in coastal region during summer and in neritic region during winter. The spawning time of E. anchoita was observed all day long, but more intensively at night. During summer there occurs a strong vertical stratification of water masses. The spawning of S. brasiliensis occurs in surface mixed layer, while that of E. anchoita occurs beneath the thermocline inside the cool South Atlantic Central Water which occupies the bottom layer during late spring and summer. However, the sardine and anchovy egss and larvae were found inside both the upper tropical and lower cold water masses, but predominantly above thermocline in this regionNeste trabalho são analisados os padrões sazonais de desova da sardinha-verdadeira, Sardinella brasiliensis, e da anchoita, Engraulis anchoita, baseado em dados coletados em águas costeiras de Ubatuba (SP), entre 1985 e 1988. Ambas as espécies habitam a costa sudeste do Brasil A primeira efetua desova durante a noite (21:00 - 23:00 h) na região costeira durante o fim da primavera e o verão, enquanto que a segunda desova durante todo o ano, principalmente na região costeira durante o verão e na região nerítica durante o inverno. A desova da anchoita foi observada ao longo de todo o dia, porém com mais intensidade à noite. No verão, ocorre uma forte estratificação vertical das massas d'água. A desova da sardinha-verdadeira ocorre na camada superficial de mistura, enquanto que a da anchoita ocorre abaixo da termoclina, nas águas frias da "Água Central do Atlântico Sul" (ACAS), que ocupam as camadas do fundo durante o verão. Entretanto, ovos e larvas de ambas as espécies foram encontrados tanto na camada superior, de água tropical, como na camada inferior, de água fria, embora predominantemente acima da termoclina

    “Coronavirus Has Changed Everything”: Emotional Experiences During Pregnancy, Birth and the Postpartum Period Among Women Impacted by COVID-19

    Get PDF
    Background: The COVID-19 pandemic may have a unique emotional impact on pregnant people. There is limited qualitative data on the lived psycho-social and emotional experiences of COVID-19+ pregnant and postpartum people during the pandemic. Objective: This cross-sectional study, which employed qualitative methodology, seeks to address this gap and characterize the emotional effects of the COVID-19 pandemic on pregnant and recently pregnant patients in the Boston area who had either suspected or confirmed COVID-19 infection during the initial four months of the pandemic. Methods: Pregnant and recently pregnant individuals (n=20) from Massachusetts General Hospital obstetrics and gynecology clinical sites with suspected or confirmed COVID-19 infection were interviewed about their experiences during the COVID-19 pandemic. Interviews were transcribed and coded using NVivo 12 software. Using data display matrices, thematic analysis was performed to identify emergent, cross-cutting themes. Results: The final sample consisted of 20 pregnant and postpartum participants who were predominantly white (65%), multigravidas (60%), married (80%), and tested positive for COVID-19 (55%). The most frequently described emotions were anxiety (90%), uncertainty (80%), fear (70%), relief (65%), and sadness (60%). The following three cross-cutting themes were identified: risk, protection, and change. The ways in which participants articulated their emotional reactions to the themes of risk, protection, and change were complex and varied. Significance: There was a broad range of negative and positive emotional experiences of pregnancy, birth, and the postpartum period during the first four months of the COVID-19 pandemic. A better understanding of pregnant people’s emotional experiences may lead to changes in clinical practice and institutional policies that are more supportive of their needs and congruent with their values.Master of Public Healt

    Does the closed fishing season influence the ichthyofauna consumed by Larus dominicanus?

    Fish that are incidentally caught by shrimp trawling represent a predictable and abundant resource for feeding several bird species, especially for the gull Larus dominicanus. This fishing activity is subject to disruptions throughout the year during closed fishing seasons, when other fishing modalities are exercised, which can alter the composition, abundance and size of the fish bycatch. This study evaluated the influence of the restriction of fishing period of shrimp (closed season) on the diet of L. dominicanus, on the Paraná State coast. From December 2013 to August 2014, 10 pellets were collected per month in two distinct areas that have shrimp trawl fishery as the main economic activity: one continental and another in an estuarine island. In total, 920 fish were identified, divided into four families and 15 species, especially the family Sciaenidae with 11 species. There were differences in abundance and biomass of species between areas and between seasons of pre-closure, closure and post-closure. Differences for the mean total length of the species were only detected between the pre-closed and closed seasons in one area. This study evidenced the strong relationship between L. dominicanus and the shrimp trawl fishery, the species composition identified in the pellets and their respective morphometric measurements follow the same pattern of the literature for fish discarded in trawling activities.As capturas incidentais de peixes no arrasto do camarão representam um recurso abundante para a alimentação de muitas aves, sobretudo para a gaivota Larus dominicanus. O presente estudo avaliou a influência do defeso da pesca de arrasto do camarão sobre a dieta de L. dominicanus no litoral do estado do Paraná. Entre dezembro de 2013 e agosto de 2014 foram coletados 10 pellets alimentares por mês em duas áreas distintas, em períodos sem e com a influência do defeso do camarão sete-barbas. Ao todo, foram identificados 920 peixes, divididos em quatro famílias e 15 espécies, com destaque para a família Sciaenidae, com 11 espécies. Foram identificadas diferenças na abundância e biomassa das espécies entre as áreas e entre os períodos de pré-defeso, defeso e pós-defeso. Diferenças em relação ao comprimento total médio das espécies só foram encontradas entre o pré-defeso e defeso em uma das áreas. Com este trabalho, foi possível observar a forte relação entre L. dominicanus e a pesca de arrasto do camarão, a composição das espécies identificadas nos pellets e as estimativas de comprimento seguem o mesmo padrão do que a literatura traz para os peixes descartados nas atividades de arrasto

    Trabalho de Conclusão de Curso (graduação)—Universidade de Brasília, Faculdade de Tecnologia, Departamento de Engenharia de Produção, 2017.A roteirização de veículos é uma importante ferramenta da pesquisa operacional e da logística para melhorar e reduzir os custos da distribuição de produtos a partir da redução das distâncias percorridas e dos tempos de trajeto. Os métodos heurísticos de roteirização podem contribuir como uma alternativa mais simples e, também, eficaz para a otimização de rotas, auxiliando as empresas a melhorarem a entrega de mercadorias aos clientes espalhados em uma determinada região geográfica. Este trabalho buscou comprovar por meio da aplicação dos métodos da Varredura, do Vizinho Mais Próximo e da Inserção do Ponto Mais Distante, se a aplicação de métodos heurísticos de roteirização é capaz de impactar positivamente na distribuição de produtos de uma fábrica de gelo no Distrito Federal, diminuindo suas distâncias percorridas e seu tempo de trajeto das rotas. Para isso, os dados foram levantados a partir de visitas realizadas à empresa e acompanhamento das rotas realizadas por ela. Os resultados obtidos com a aplicação dos métodos heurísticos foram melhores do que quando realizados empiricamente, no qual o método da Inserção do Ponto Mais Distante apresentou os melhores resultados.The vehicle routing is an important operational research and logistics tool for the improvement and the reduction of products distribution costs, by minimizing the distances traveled and the travel times. Heuristic routing methods can contribute as a simpler and more effective route optimization alternative, helping companies improve the delivery of its products to customers spread in a particular geographic region. This work sought to prove, through the application of the Sweep Method, the Nearest-Neighbor Algorithm and the Insertion Of The Vertex Furthest Away From The Tour, if the application of heuristic routing techniques is capable of positively impacting the distribution of products from an ice factory in the Federal District, reducing its distances traveled and its travel time of the routes. To do so, the data was collected from visits made on the company and follow-ups of the routes performed by it. The results obtained with the application of the heuristic methods were better than when done empirically, in which the method of the Insertion of The Vertex Furthest Away From The Tour presented the best results
