    Brazil is the third largest producer and exporter of turkey meat, especially in Paraná state, with the largest production volume. In worldwide the animal welfare is a prerequisite for food quality of animal origin, especially in Europe. The Regulation of European Community No 1099/2009 provides requirements for poultry stunning that associate with animal welfare as a means to minimize the pain and suffering from the slaughter. Improper application of callousness should produce low-quality meat, and significant industry losses. This Research aimed to evaluate the impacts on the quality of meat from turkeys, applying electrical stunning parameters established in the Regulation No 1099/2009 of the Council of 24 September 2009. Was applied an outline with 8 tests set equidistantly to frequency, and set parameters for current and voltage, and a control test. Were conducted qualitative assessments of hematoms and bruises / fractures in carcasses, hematoms, blood splashed and bleeding in turkey breast, and quantitative pH, color (L *), water holding capacity and shear force in turkey breast. The individual assessments showed no significant difference (p>0,05). In multivariate cluster analysis was the formation of two distinct groups: group 1 - 50 Hz to 200 Hz (low frequency) and group 2 - 633 Hz to 1500 Hz (high frequency), which showed significant difference (p= 0,016). In principal component analysis multivariate, the group 1 tend to have a higher incidence of bruising, blood splashed, bleeding and water holding capacity in breast turkeys, and bruises / fractures and hematoms on carcasses. The Group 2 tends to have a lower incidence of these parameters, and higher pH values, shear force and color (L *). Positive correlation was obtained for the parameters pH and shear force (r= 0.7506, p=0.0198); bleeding and splashed blood (r= 0.8811, p= 0.0017), and negative correlation to color (L*) and splashed blood on breast (r= -0.7889; p= 0.0115); breast hematoms and shear force (r= -0.7844; p= 0.0123). It has been observed that at lower frequencies stunning tends to have higher incidence of defects in the carcasses and turkey breast. The use of high frequencies in stunning, create smaller quantity of trimming, and an increase in turkey breast volume produced, with a financial gain of approximately R250,000.00/year.Moreover,thereisnoneedincreasetheworkerstodothetrimmingtasksand,therefore,higherfinancialresultsforcompanies.Therefore,werecommendtheuseofhighfrequenciesinthestunningofturkeys.OBrasileˊoterceiromaiorprodutoreexportadormundialdecarnedeperus,comdestaqueparaoestadodoParanaˊ,comomaiorvolumedeproduc\ca~o.Obemestaranimaleˊumpreˊrequisitodequalidadeparaosprodutosalimentıˊciosdeorigemanimalemtodomundo,comdestaqueparaEuropa.ORegulamentodaComunidadeEuropeˊian°1099/2009apresentarequisitosparainsensibilizac\ca~odeavesqueseassociamaobemestaranimalcomoummeiodeminimizaradoreosofrimentoprovenientedoabate.Aaplicac\ca~oinadequadadainsensibilizac\ca~opodeproduzircarnesdebaixaqualidade,ecomperdassignificativasparainduˊstria.Oobjetivodapesquisafoiavaliarosimpactosdaaplicac\ca~odospara^metrosdeinsensibilizac\ca~oeleˊtricadoRegulamentodaComunidadeEuropeˊian°1099/2009,doConselhode24desetembrode2009,naqualidadedacarnedeperus.Foiaplicadoumdelineamentocom8ensaios,definidosdeformaequidistanteparafreque^ncia,epara^metrosfixosparacorrenteetensa~o,eumensaiocontrole.Foramrealizadasavaliac\co~esqualitativasdehematomasecontuso~es/fraturasemcarcac\cas,hematomas,salpicamentodesangueehemorragiasempeitodeperu,equantitativasdepH,cor(L),capacidadederetenc\ca~odeaˊgua,eforc\cadecisalhamentoempeitodeperu.Asavaliac\co~esindividuaisna~oapresentaramdiferenc\casignificativa(p>0,05).Naanaˊlisemultivariadadeagrupamentoocorreuaformac\ca~odedoisgruposdistintos,sendo:grupo150Hza200Hz(freque^nciasbaixas)egrupo2633Hza1500Hz(freque^nciaselevadas),osquaisapresentaramdiferenc\casignificativa(p=0,016).Naanaˊlisemultivariadadecomponentesprincipais,ogrupo1tendeaapresentarmaiorincide^nciadehematomas,salpicamentodesangue,hemorragiasecapacidadederetenc\ca~odeaˊguaempeitodeperus,efraturas/contuso~esehematomasemcarcac\cas.Ogrupo2tendeaapresentarmenorincide^nciadestespara^metros,emaioresvaloresdepH,forc\cadecisalhamentoecor(L).Obtevesecorrelac\ca~opositivaparaospara^metrospHeforc\cadecisalhamento(r=0,7506;p=0,0198);hemorragiasesalpicamentodesangue(r=0,8811;p=0,0017);ecorrelac\ca~onegativaparacor(L)esalpicamentodesangueempeito(r=0,7889;p=0,0115);hematomasdepeitoeforc\cadecisalhamento(r=0,7844;p=0,0123).Observousequemenoresfreque^nciasnainsensibilizac\ca~otendemaapresentarmaiorincide^nciadeanomaliasnacarcac\caepeitodeperu.Autilizac\ca~odealtasfreque^nciasnainsensibilizac\ca~o,geramenorquantidadedeperdas,eumacreˊscimonovolumedepeitodeperuproduzido,comumganhofinanceirodeaproximadamenteR250,000.00 / year.

O bem estar animal é um pré requisito de qualidade para os produtos alimentícios de origem animal em todo mundo, com destaque para Europa. O Regulamento da Comunidade Européia n° 1099/2009 apresenta requisitos para insensibilização de aves que se associam ao bem estar animal como um meio de minimizar a dor e o sofrimento proveniente do abate. A aplicação inadequada da insensibilização pode produzir carnes de baixa qualidade, e com perdas significativas para indústria. O objetivo da pesquisa foi avaliar os impactos da aplicação dos parâmetros de insensibilização elétrica do Regulamento da Comunidade Européia n° 1099/2009, do Conselho de 24 de setembro de 2009, na qualidade da carne de perus. Foi aplicado um delineamento com 8 ensaios, definidos de forma equidistante para frequência, e parâmetros fixos para corrente e tensão, e um ensaio controle. Foram realizadas avaliações qualitativas de hematomas e contusões/fraturas em carcaças, hematomas, salpicamento de sangue e hemorragias em peito de peru, e quantitativas de pH, cor (L*), capacidade de retenção de água, e força de cisalhamento em peito de peru. As avaliações individuais não apresentaram diferença significativa (p>0,05). Na análise multivariada de agrupamento ocorreu a formação de dois grupos distintos, sendo: grupo 1 – 50 Hz a 200 Hz (frequências baixas) e grupo 2 – 633 Hz a 1500 Hz (frequências elevadas), os quais apresentaram diferença significativa (p= 0,016). Na análise multivariada de componentes principais, o grupo 1 tende a apresentar maior incidência de hematomas, salpicamento de sangue, hemorragias e capacidade de retenção de água em peito de perus, e fraturas/contusões e hematomas em carcaças. O grupo 2 tende a apresentar menor incidência destes parâmetros, e maiores valores de pH, força de cisalhamento e cor (L*). Obteve-se correlação positiva para os parâmetros pH e força de cisalhamento (r= 0,7506; p= 0,0198); hemorragias e salpicamento de sangue (r= 0,8811; p= 0,0017); e correlação negativa para cor (L*) e salpicamento de sangue em peito (r= -0,7889; p= 0,0115); hematomas de peito e força de cisalhamento (r= -0,7844; p= 0,0123). Observou-se que menores frequências na insensibilização tendem a apresentar maior incidência de anomalias na carcaça e peito de peru. A utilização de altas frequências na insensibilização, gera menor quantidade de perdas, e um acréscimo no volume de peito de peru produzido, com um ganho financeiro de aproximadamente R250.000,00 / ano. Além disso, não há necessidade no incremento de colaboradores para realizar a tarefa de espostejamento e, portanto, resulta em maiores ganhos financeiros para as empresas. Portanto, é recomendável a utilização de frequências elevadas na insensibilização de perus

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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 text
    In 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.
