Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Assessment of the cross-protective capability of recombinant capsid proteins derived from pig, rat, and avian hepatitis E viruses (HEV) against challenge with a genotype 3 HEV in pigs
No full textHepatitis E virus (HEV), the causative agent of hepatitis E, is primarily transmitted via the fecal-oral route through contaminated water supplies, although many sporadic cases of hepatitis E are transmitted zoonotically via direct contact with infected animals or consumption of contaminated animal meats. Genotypes 3 and 4 HEV are zoonotic and infect humans and other animal species, whereas genotypes 1 and 2 HEV are restricted to humans. There exists a single serotype of HEV, although the cross-protective ability among the animal HEV strains is unknown. Thus, in this study we expressed and characterized N-terminal truncated ORF2 capsid antigens derived from swine, rat, and avian HEV strains and evaluated their cross-protective ability in a pig challenge model. Thirty, specific-pathogen-free, pigs were divided into 5 groups of 6 pigs each, and each group of pigs were vaccinated with 200 μg of swine HEV, rat HEV, or avian HEV ORF2 antigen or PBS buffer (2 groups) as positive and negative control groups. After a booster dose immunization at 2 weeks post-vaccination, the vaccinated animals all seroconverted to IgG anti-HEV. At 4 weeks post-vaccination, the animals were intravenously challenged with a genotype 3 mammalian HEV, and necropsied at 4 weeks post-challenge. Viremia, fecal virus shedding, and liver histological lesions were compared to assess the protective and cross-protective abilities of these antigens against HEV challenge in pigs. The results indicated that pigs vaccinated with truncated recombinant capsid antigens derived from three animal strains of HEV induced a strong IgG anti-HEV response in vaccinated pigs, but these antigens confer only partial cross-protection against a genotype 3 mammalian HEV. The results have important implications for the efficacy of current vaccines and for future vaccine development, especially against the novel zoonotic animal strains of HEV

Alimentos de rua em Florianóplis: perfil do manipulador e características dos alimentos comercializados
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em NutriçãoO comércio informal de alimentos de rua desempenha papel importante em muitos países, destacando-se como fonte de emprego e de variedade de alimentos convenientes e acessíveis para as pessoas. Por outro lado, apresenta aspectos que podem comprometer a segurança dos alimentos comercializados. Apesar da importância dos alimentos de rua há poucos estudos na maioria dos municípios brasileiros, inclusive em Florianópolis, onde o estudo foi realizado. O objetivo deste estudo foi caracterizar o perfil do manipulador de alimentos de rua e os alimentos comercializados na região central da cidade de Florianópolis-SC. Realizou-se um estudo exploratório, descritivo, de natureza quali-quantitativa, com todos os vendedores de alimentos de rua cadastrados na lista da prefeitura local, que operavam em pontos de venda estacionários. Foram coletadas informações sobre as características sociodemográficas, gerais, do ponto de venda e as práticas de higiene do vendedor por meio de observação e de um roteiro de entrevista estruturado, pré-testado, entre novembro e dezembro de 2011. Dentre os 50 participantes do estudo, 60% eram do sexo masculino, a maior parte era casada e tinha idade entre 40 e 59 anos. Predominaram vendedores sem ensino formal ou fundamental incompleto e com estimativa de venda em reais de até dois salários mínimos. A partir dos dados sobre a atividade laboral, verificou-se que os pontos de vendas eram operados, em sua maioria, por um vendedor e que 90% não tinham outra fonte de renda. O interesse e a dificuldade em encontrar outro emprego foram os principais motivos que levaram os vendedores a trabalharem com a atividade. Dentre os vendedores, 46% nunca haviam realizado o curso para manipulação de alimentos e 28% não tinham o atestado de saúde. Com relação às práticas de higiene, foi observado que 86% dos vendedores usavam jaleco e o mantinham limpo. A maioria protegia parcialmente os cabelos com touca ou boné e quase ¾ usavam adornos. Dentre os 15 tabagistas deste estudo, 20% informaram fumar durante o preparo dos alimentos. Observou-se que quase todos manipulavam o dinheiro e o alimento, sem higienizar as mãos. Com base nas informações sobre o tipo de alimento comercializado, verificou-se que 30% dos participantes vendiam pipoca preparada no ponto de venda; 28%, doces e salgadinhos industrializados; 20%, cachorro-quente e churrasquinho; 22%, alimentos preparados com antecedência ou pré-preparados e finalizados no ponto de venda. O percentual de vendedores que tinha o curso para manipulação de alimentos foi maior para os de alimentos preparados antecipadamente ou pré-preparados e finalizados no ponto de venda, do que os de industrializados. A partir deste estudo, verificou-se que o comércio de alimentos de rua representa para muitos vendedores sua única fonte de renda e, que a maioria dos pontos de venda é operada por apenas um vendedor, que não movimenta a economia. Por meio dos vendedores, as pessoas que transitam pelo centro da cidade e os comerciantes têm disponíveis alimentos prontos e regionais, como o pinhão. Embora uma exigência legal, verificou-se que quase metade dos vendedores nunca havia feito o curso para manipulação de alimentos e 28% não tinham o atestado de saúde. Entre as práticas de higiene inadequadas observadas neste estudo destacam-se: manuseio de dinheiro e alimento sem higienizar as mãos; fumar durante o preparo dos alimentos; proteção parcial dos cabelos e uso de adornos. Constata-se a necessidade de repensar os treinamentos ofertados, a fim de que sejam efetivos para que os vendedores cumpram as normas básicas de higiene. Aos órgãos competentes cabe verificar a razão pela qual as exigências dispostas na lei não estão sendo cumpridas e o vendedor continua tendo seu alvará de licença renovado. Ainda, tornar mais eficientes as maneiras de verificar as razões pelas quais tais exigências e as boas práticas de higiene não estão sendo seguidas. Por fim, formular normas específicas para a venda de alimentos de rua e proporcionar infraestrutura básica e adequada ao vendedor.The informal trade of street food plays an important role in many countries, especially as a source of employment and of convenient and affordable food for people. On the other hand, it has aspects that may compromise food safety. Despite the importance of street food, there are few studies in most Brazilian cities, including Florianópolis, where this research was conducted. The aim of this study was to characterize the street food vendor profile and the food marketed in the central region of the city of Florianópolis-SC. An exploratory, descriptive, qualitative and quantitative study was held with all street food vendors registered with the local government, which operated in stationary points of sale. Information regarding general and sociodemographic characteristics, as well as good manipulation practices of the stationary vendors was collected through a pre-tested and well structured interview questionnaire, between November and December 2011. Among the 50 participants of the study, 60% were male; most were married and aged between 49 and 50 years. Their level of education was predominantly low and their average monthly income was between one and two minimum wages. The data collected about labour activity showed that the semi-permanent stationary vending stalls were mostly operated by a single seller and that 90% of them had no other source of income. The interest and the difficulty in finding another job were the main reasons that led vendors to work on this activity. Among the sellers, 46% had not received training in food handling and 72% had a health certificate. In relation to hygienic handling of street-vended foods, it was observed that 86% of the sellers wore a uniform or overall, changed daily and kept clean. More than half of the sellers partially covered their hair with a hair cap and approximately ¾ wore jewelry. Among the 15 sellers who were smokers, 20% informed smoking during food preparation. It was observed that almost all sellers handled money and food without cleaning their hands. Based on information about the type of food marketed, it was found that 30% of the participants sold prepared popcorn at the point of sale; 28% sold industrialized snacks and sweets and 20%, hot dog and barbecue; 22% sold food previously prepared or pre-prepared and finalized on the point of sale. The percentage of sellers that had taken the food handling course was higher for sellers of previously prepared or finalized food on the point of sale (cocada, pamonha, bonbon and churros), than those of industrialized snacks and sweets. From this study, it would appear that the street food trade represents, for many sellers, a source of employment and the only source of income. It was also observed that most of the points of sale were operated by only one seller that does not move the economy. Through the work of these street food vendors, people going through the city center, as well as traders, have available local and ready-to-eat foods, like the pine nut. Although a legal obligation, it was observed that almost half of the sellers had never had course of food handling and 28% had no health certificate. Among the inadequate hygienic practices observed in this study the following outstand: the handling of money and food without cleaning hands, smoking during food preparation, partial protection of the hair and use of jewelry. There is a need to rethink the trainings offered in order to be more effective and have the sellers following the basic rules of hygiene. With regards to regulatory organizations, it is their responsibility to verify why obligations existing in the law are not being followed and sellers continue to have permits renewed. Nevertheless, it is necessary to find more efficient ways to verify the reasons why these obligations and good handling practices are not being followed. Finally, it is necessary to formulate specific rules for the street food segment and provide some basic and adequate infrastructure to vendor

Factors associated with selling price of cattle at livestock marts
No full textpeer-reviewedThe objective of this study was to determine the factors associated with selling price of animals at livestock marts around Ireland.
Data consisted of four distinct maturity categories: calves (2 to 84 days of age, n553 838); weanlings (6 to 12 months of age,
n519 972); post-weanlings (12 to 36 months of age, n593 081) and cows (.30 months to 12 years of age, n594 839); sold through livestock marts between 2000 and 2008. Factors associated with animal price were determined within each maturity
category separately using mixed models; random effects were mart, date of sale nested within mart, and herd of origin nested
within year of sale. Mean selling price was h157, h580, h655 and h592 for calves, weanlings, post-weanlings and cows,
respectively. The greatest prices were paid for singleton crossbred male calves, weanlings and post-weanlings from older dams.
With the exception of the Aberdeen Angus, beef breeds and their crosses consistently received higher prices than their dairy
counterparts across all four maturity categories; increased proportion of Belgian Blue and Charolais was associated with greater prices compared with other beef breeds. When live-weight was included in the multiple regression models the association
between price and all factors regressed toward zero but most factors remained associated with price. The highest price was
recorded in the spring months for calves, post-weanlings and cows, and in the autumn months for weanlings. Results from this
study may be used to help farmers make more informed management decisions, as well as provide information for bio-economic
models for evaluating alternative production systems or estimating economic values
