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
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
Determination and identification of viruses in naturally infected honeybee colonies (Apis mellifera carnica) and development of the infection after honeybee brood virus inoculation
No full textV raziskavi smo ugotavljali in določali viruse v naravno okuženih čebeljih družinah (Apis mellifera carnica) in preučevali razvoj virusne okužbe v inokulirani čebelji zalegi. Razvili in uporabili smo nove začetne oligonukleotide, sondi TaqMan in standarda za kvantitativno metodo reverzne transkripcije in verižne reakcije s polimerazo v realnem času (RT-qPCR) za določitev in kvantifikacijo virusa Lake Sinai linije 3 (LSV3) in virusa mešičkaste zalege (SBV). Z metodo RT-qPCR smo pregledali 89 vzorcev klinično obolelih čebeljih družin, vzorčenih med aprilom 2016 in septembrom 2020, in 108 vzorcev klinično zdravih čebeljih družin, vzorčenih med oktobrom 2018 in oktobrom 2019, in ugotavljali, ali so prisotni čebelji virusi: virus akutne paralize čebel (ABPV), virus črnih matičnikov (BQCV), virus kronične paralize čebel (CBPV), virus deformiranih kril (DWV), LSV3 in SBV. Prisotnost ABPV smo ugotovili v 29,63 % klinično zdravih in 79,78 % klinično obolelih čebeljih družin, BQCV v 98,15 % klinično zdravih in 96,63 % klinično obolelih čebeljih družin. Prisotnosti CBPV nismo ugotovili v nobenem vzorcu klinično zdravih čebeljih družin, v klinično obolelih čebeljih družinah pa v 19,10 %. DWV smo ugotovili v 39,81 % zdravih in 69,66 % obolelih čebeljih družin, LSV3 pa v 67,59 % klinično zdravih in 48,31 % klinično obolelih čebeljih družin. Prisotnost SBV smo ugotovili v 35,19 % klinično zdravih in 22,47 % obolelih čebeljih družin. Statistično značilno višje število kopij smo ugotovili pri klinično obolelih čebeljih družinah, okuženih z ABPV, CBPV, DWV in SBV (p < 0,0001), medtem ko pri BQCV (p = 0,6597) in LSV3 (p = 0,0062) statistično značilnih razlik med zdravimi in obolelimi čebeljimi družinami nismo ugotovili. Iz devetih vzorcev klinično obolelih in desetih vzorcev klinično zdravih čebeljih družin, v katerih smo z določanjem nukleotidnega zaporedja po Sangerju predhodno ugotovili različne linije čebeljih virusov, smo z metodo sekvenciranja naslednje generacije (NGS) določili 22 nukleotidnih zaporedij celotnih genomov čebeljih virusov, in sicer ABPV (n = 4), BQCV (n = 3), CBPV (n = 2), DWV (n = 5), LSV (n = 4), SBV (n = 1), Apis Rhabdovirus-1 ali ARV-1 (n = 1), Bee Macula-like virus ali BeeMLV (n = 1), Hubei partiti-like virus 34 ali HPLV34 (n = 1). Nukleotidna zaporedja genomov ABPV, BQCV, DWV in SBV so prva nukleotidna zaporedja celotnih genomov teh vrst virusov, identificiranih v Sloveniji. Nukleotidna zaporedja genomov ARV-1, BeeMLV in HPLV34 smo na območju Slovenije ugotovili prvič, zato odkritje predstavlja pomemben doprinos k ugotovljeni genetski raznovrstnosti čebeljih virusov pri nas in po svetu. Z namenom raziskovanja pomnoževanja čebeljih virusov in razvoja virusnih okužb pri ličinkah smo uporabili in vitro metodo gojenja čebeljih ličink. V razvojni fazi čebelje ličinke, od prvega do petega dneva starosti, smo z inokulacijo terenskih sevov LSV3 in SBV (per os) preučevali pomnoževanje virusov in umiranje ličink. Pomnoževanja LSV3 in SBV v ličinkah nismo ugotovili, prav tako nismo ugotovili značilnih razlik v umiranju ličink glede na različne odmerke virusa. Uvedene metode imajo velik potencial za nadaljnje študije virusnih, bakterijskih in drugih okužb pri čebelah.In this study honeybee viruses in naturally infected honeybee colonies (Apis mellifera carnica) were determined and identified. Furthermore, the development of the viral infection after honeybee brood virus inoculation was studied. Two new sets of primers, TaqMan probes and standards for quantitative method of real-time reverse transcription and polymerase chain reaction (RT-qPCR) for detection and quantification of Lake Sinai virus lineage 3 (LSV3) and sacbrood bee virus (SBV) were developed and implemented. 89 samples of clinically affected honeybees sampled from April 2016 to September 2020 and 108 samples of clinically healthy honeybee colonies sampled over one year period from October 2018 to October 2019, were examined with RT-qPCR methods, for presence of six honeybee viruses: acute bee paralysis virus (ABPV), black queen cell virus (BQCV), chronic bee paralysis virus (CBPV), deformed wing virus (DWV), LSV3 and SBV. ABPV was detected in 29,63 % of clinically healthy and 79,78 % of clinically affected honeybee colonies, BQCV was detected in 98,15 % of clinically healthy and 96,63 % of clinically affected honeybee colonies. CBPV was not detected in any sample of clinically healthy but was detected in 19,10 % of clinically affected honeybee samples. DWV was detected in 39,81 % of healthy and 69,66 % of affected honeybee colonies, LSV3 was detected in 67,59 % of healthy and 48,31 % of affected honeybee colonies. SBV was detected in 35,19 % of healthy and in 22,47 % of affected honeybee colonies. There were statistically significantly higher viral copy numbers detected in clinically affected honeybee colonies infected with ABPV, CBPV, DWV in SBV (p < 0,0001), but with BQCV (p= 0,6597) and LSV3 (p=0,0062) there were no statistically significant differences detected in viral copy numbers between healthy and affected honeybee colonies. From nine samples of clinically affected and ten samples of healthy honeybee colonies in which different strains of honeybee viruses were detected by Sanger sequencing, 22 nucleotide sequences of complete genomes of honeybee viruses were determined with next generation sequencing (NGS) method (ABPV n=4, BQCV n=3, CBPV n=2, DWV n=5, LSV n=3, SBV n=1, Apis Rhabdovirus-1 (ARV-1) n=1, Bee Macula-like virus (BeeMLV) n=1, Hubei partiti-like virus 34 (HPLV34) n=1). Nucleotide sequences of complete genomes of ABPV, BQCV, DWV and SBV are first nucleotide sequences of complete genomes of this viral species determined in Slovenia. ARV-1, BeeMLV and HPLV34 were detected in Slovenia for the first time and they represent important contribution to genetic diversity of honeybee viruses identified in Slovenia and over the world. With the goal to research the replication of honeybee viruses and development of viral infections, we implemented the method of in vitro rearing of honeybee larvae. In the developing phase of honeybee larva from day one to day five, with inoculation of field strains of LSV3 and SBV per os, viral replication and dying of larvae were studied. The replication of LSV3 and SBV in the larvae was not determined and significant differences in dying of larvae depending on different viral doses were not detected. The implemented methods have great potential for further studies of viral, bacterial and other infections on the developing stages of honeybees
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.
