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
Dethiobacteraceae fam. nov.
No full textDe.thi’o.bac.ter.a.ce.a.e. N.L. masc. n. Dethiobacter, the type genus of the family; L. fem. pl. n. suff. -aceae, ending to denote a family; N.L. fem. pl. n. Dethiobacteraceae, the family of the genus Dethiobacter. The family Dethiobacteraceae includes obligately anaerobic, moderately salt-tolerant, and obligately alkaliphilic bacteria able to grow chemolithoautotrophically by elemental sulfur disproportionation and fixingCO2 by the Wood–Ljungdahl pathway. The two strains currently known in pure culture are both isolated from saline soda lakes. H2 can serve as an additionalelectron donor for sulfur and thiosulfate reduction. The family consists of a single genus Dethiobacter with the type species Dethiobacter alkaliphilus. DNA G +C content (%): 48.3–48.5 (genomes of two isolates).

Natronospira
No full textNa.tro.no.spi’ra. N.L. neut. n. natron (arbitrarily derived from the Arabic n. natrun or natron), soda; L. fem. n. spira, coil; N.L. fem. n. Natronospira, a soda-loving coil-shaped bacterium.The genus Natronospira was originally classified as a member of the family Ectothiorhodospiraceae, order Chromatiales, and class Gammaproteobacteria, according to the 16S rRNA-based gene sequence comparison, while according to the phylogenomic analysis it forms a separate order-level branch within the Gammaproteobacteria unrelated to the Chromatiales members. It is an aerobic heterotroph that preferably utilizes proteins and peptides for growth. Natronospira is an extremely salt-tolerant, chloride-independent obligate alkaliphile. It inhabits oxic brines of hypersaline soda lakes, particularly in southwestern Siberia. The genus currently includes a single (type) species:N. proteinivora. DNA G +C content (%): 59.8 (genome).

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
Natronoflexus
No full textNa.tro.no.fle’xus; N.L. neut. n. natron (arbitrarily derived from the Arabic n. natrun or natron) soda, sodium carbonate; N.L. pref. natrono-, pertaining to soda; L. masc. n. flexus, a bending, N.L. masc. n. Natronoflexus, bending/flexible cells living in soda. The genus Natronoflexus is a member of the family Marinilabiliaceae, order Bacteroidales, class Bacteroidia, and phylum Bacteroidota. It is an obligately anaerobic fermentative saccharolytic bacterium with the ability to utilize polygalacturonates and xylan as carbon and energy sources. The only species of the genus, N. pectinivorans, is a moderately salt-tolerant, chloride-independent obligate alkaliphile found in soda lakes in Central Asia. The DNA G+C content is 39.6mol% (genome). DNA G +C content (%): 39.6 (genome).

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
