Ideal slaughter weight of Jersey bulls for meat production
No full textWith the growth of dairy farming in Brazil the chances of the use of the males for meat production increase. Thus, the objective of this work was to evaluate the best slaughter weight of Jersey bulls, aiming at the optimization of the use of these whole animals for meat production, evaluating the performance characteristics of the animals, carcass characteristics and slaughtered meat. The experimental design was a completely randomized design with three slaughter weights (360, 390 and 420 kg), with six replicates. The experiment was conducted at the Agronomic Institute of Paraná (IAPAR) of Pato Branco from May 2017 to September 2018. Eighteen newborns of the Jersey breed were used. The animals were submitted to a single lactation system, which consisted of four liters of milk, supplied twice a day for 51 days. The diet provided after breastfeeding consisted of 15% of oat hay, 68% whole corn grain and 17% soybean meal. There was a period of adaptation to the facilities and the management system employed, with duration of 15 days. The animals were weighed at the beginning and end of the experimental period, as well as every 28 days, for monitoring the ponderal development. After slaughter the animals were submitted to carcass evaluations. Absolute dry matter intake (CMS), mean daily weight gain (GMD) and feed conversion were not affected by the slaughter weight of the animals (P> 0.05). The thickness of the subcutaneous fat decreased from the animals slaughtered with 392 to those of 422 kg, causing the animals to present less requirement for gain, compensating the fall of the dry matter consumption relative to 100 kg of live weight. The warm carcass weight and cold carcass weight increased linearly with the increase in slaughter weight of the animals.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Com o crescimento da exploração leiteira no Brasil aumentam-se as chances do aproveitamento dos machos para produção de carne. Assim o objetivo deste trabalho foi avaliar o melhor peso de abate de tourinhos Jersey, visando a otimização da utilização desses animais inteiros para a produção de carne, avaliando as características de desempenho dos animais, características da carcaça e da carne dos animais abatidos. O delineamento experimental utilizado foi o inteiramente casualizado contendo três pesos de abate (360, 390 e 420 kg), com seis repetições. O experimento foi conduzido no Instituto Agronômico do Paraná (IAPAR) de Pato Branco, no período de maio de 2017 a setembro de 2018. Foram utilizados 18 animais recém nascidos da raça Jersey. Os animais foram submetidos a um único sistema de aleitamento, que consistiu de quatro litros de leite, fornecidos duas vezes ao dia durante 51 dias. A dieta fornecida pós aleitamento foi constituída por 15% de feno de aveia, 68% grão de milho inteiro e 17% farelo de soja. Houve um período de adaptação às instalações e ao sistema de manejo empregado, com duração 15 dias. Os animais foram pesados no início e final do período experimental, assim como a cada 28 dias, para acompanhamento do desenvolvimento ponderal. Após abate os animais foram submetidos às avaliações de carcaça. O consumo absoluto de matéria seca (CMS), o ganho de peso médio diário (GMD) e a conversão alimentar não foram afetados pelo peso de abate dos animais (P>0,05). A espessura de gordura subcutânea decresceu dos animais abatidos com 392 para os de 422 kg, fazendo com que os animais apresentassem menor exigência para ganho, compensando a queda do consumo de matéria seca relativo a 100 kg de peso vivo. O peso de carcaça quente e peso de carcaça fria aumentaram linearmente com o aumento do peso de abate dos animais
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
