Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Lactobacillus strategies to reduce Campylobacter jejuni colonization of broiler chickens
Get PDFCampylobacter jejuni is one of the leading causes of foodborne bacterial illness in the world. The majority of cases of campylobacteriosis are associated with the consumption of raw or undercooked poultry meat or their cross-contamination with other food products. Strategies to reduce the presence of Campylobacter in the poultry supply are underdeveloped. The probiotic Lactobacillus spp. are a viable delivery vehicle for mucosal vaccines due to the Generally Recognized As Safe (GRAS) status. In addition, recombinant lactobacilli present proteins to the mucosal surface and elicit host immune responses. The overall objectives of this research were to 1) colonize broiler chickens with C. jejuni; 2) construct recombinant Lactobacillus for oral delivery of vaccines against C. jejuni; and 3) evaluate the immunogenicity of the recombinant Lactobacillus strains in broiler chickens. To meet these objectives, broiler chickens were orally administered with 109 CFU/mL of C. jejuni NCTC 11168 on d 14, then necropsied on d 21 for direct-plating of the cecal contents. Results indicate successful C. jejuni colonization of the cecal crypts. Lactobacillus strains were engineered to express C. jejuni FlpA Domain II under a promoter fused to a secretion signal with or without an anchoring signal from the mucus-binding protein of Lactobacillus acidophilus NCFM. Additional work must be conducted to evaluate the exterior protein expression and in vivo antigen-immune response within broiler chickens. If successful, the recombinant Lactobacillus strain could be an attractive candidate as a food-grade live vaccine against Campylobacter colonization. In addition, a non-genetically modified delivery approach proposes attachment of C. jejuni FlpA to the cell wall of lactobacilli utilizing one of three cell wall binding domains. Reduction of Campylobacter at the poultry farm decreases the introduction of the bacteria into the retail market and decreases the incidence of campylobacteriosis.Item withdrawn by Mark Zulauf ([email protected]) on 2014-07-11T19:03:39Z

Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Disqualifying Conduct: How Failure to Regulate the United States Olympic Committee Enables Athlete Abuse
Get PDFIn the aftermath of the USA Gymnastics Scandal, Congress passed the Protecting Young Victims from Sexual Abuse and Safe Sport Authorization Act of 2017 and Empowering Olympic, Paralympic, and Amateur Athletes Act of 2020 to protect athletes from abuse. This comment examines how years of unregulated Olympic Sport controlled by the United States Olympic and Paralympic Committee (USOPC) created systems that make young athletes vulnerable to abuse. Part I provides a background of the Olympic Movement, specifically detailing events and legislation that prompted recent legislation. Part II describes the Safe Sport Authorization Act of 2017 and Empowering Olympic, Paralympic, and Amateur Athletes Act of 2020 and addresses their limits amidst the current culture of Olympic Sports. Specifically, it provides a case study of Track and Field coach Alberto Salazar, who abused athletes despite the Center for Safe Sport. Part III suggests measures that would not completely undermining the Amateur Sports Act, the current law establishing the USOPC. Part IV details an alternative suggestion, regulating Olympic Sport safety and wellbeing through on office within a larger administrative agency, such as the Department of Labor or Department of Health and Human Services. Administrative control and regulation may be particularly pertinent as the United States hosts the 2028 Olympic Games
