Whole-Genome Draft Sequences of Six Commensal Fecal and Six Mastitis-Associated Escherichia coli Strains of Bovine Origin.
Full text linkThe bovine gastrointestinal tract is a natural reservoir for commensal and pathogenic Escherichia coli strains with the ability to cause mastitis. Here, we report the whole-genome sequences of six E. coli isolates from acute mastitis cases and six E. coli isolates from the feces of udder-healthy cows
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
Protection against transplacental transmission of Classical swine fever virus using live marker vaccine “CP7_E2alf"
No full textClassical swine fever is one of the most important diseases in swine and despite implemented eradication programs still present in many countries worldwide. Recently, the live marker vaccine “CP7_E2alf” (Suvaxyn® CSF Marker, Zoetis), has been licensed by the European Medicines Agency. However, data are still missing regarding the use on breeding farms, expecially in breeding sow herds. A major concern was the protection against vertical transmission of CSFV. Since transmission of virus in mid‐gestation can lead to persistently infected offspring, it was important to show that the vaccine is able to protect the fetuses against an infection with CSFV. Along these lines, a study was conducted according to the guidelines of the OIE Manual of Diagnostic Tests and Vaccines. A relevant, moderately virulent CSFV strain was used for challenge purposes. It was demonstrated that the vaccine protected the fetuses completely against an infection with CSFV and fulfilled all requirements of the guidelines. No virus was found in the blood of vaccinated sows and their fetuses, and also no antibodies were found in the serum of the fetuses from the vaccinated sows. Furthermore, all of the fetuses of the control group tested positive for viral genome in qPCR and tested positive in virus isolation. This study provided solid data, that it might not be necessary to exclude sows and breeding farms from (emergency) vaccination programs.Die Klassische Schweinepest (KSP) gehört bis heute zu den wichtigsten Infektionskrankheiten im Bereich der Schweineproduktion und ist trotz massiver Bekämpfungsmaßnahmen weltweit immer noch in vielen Ländern verbreitet. Vor kurzem wurde der Lebendmarkerimpfstoff “CP7_E2alf” (Suvaxyn® CSF Marker, Zoetis) nach eingehender Prüfung durch die Europäische Arzneimittel-Argentur (European Medicines Agency, EMA) zugelassen. Trotzdem bestehen noch einige Wissenlücken, insbesondere in Bezug auf den Einsatz in Zuchtsauenbetrieben. Ein besonderes Augenmerk lag hierbei auf dem Schutz vor transplazentarer Übertragung des Virus auf die Föten, da es bei einer solchen Übertragung im mittleren Drittel der Trächtigkeit zur Geburt von persistierent infizierten Ferkeln kommen kann, welche eine Immuntoleranz gegenüber dem Virus zeigen und es durch Ausscheidung unkontrolliert weiterverbreiten können. In der vorliegenden Studie wurde geprüft, ob eine Impfung der Muttersau den Fetus vor einer Infektion mit dem Virus der Klassichen Schweinepest (KSPV) schützt. Der Versuchsaufbau entsprach den Vorgaben des Diagnosehandbuchs der Weltorganisation für Tiergesundheit. Als Material für die Belastungsinfektion der Tiere wurde ein aktueller moderat virulenter KSPV-Stamm verwendet. Es konnte gezeigt werden, dass eine einmalige Impfung der Sau die Föten vor einer Infektion mit KSPV schützt. Es konnten kein Virus und keine Antikörper im Blut und den Organen der Föten nachgewiesen werden, darüber hinaus wurden alle Tiere der Kontrollgruppe positiv in der Virusisolierung und im Genormnachweis getestet. Die gewonnenen Ergebnisse erfüllen somit alle Anforderungen des Handbuchs. Die in dieser Studie gewonnen Daten zeigen umfassend, dass es nicht unbedingt nötig ist, Sauen und Zuchtbetriebe von (Not)-Impfprogrammen auszuschließen
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
