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
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
Systemic transcriptional profiling of immune cell heterogeneity in autoimmune disease
No full textWas sind die genomischen Fußabdrücke der Immunaktivierung? Diese Dissertation geht
dieser Frage nach, indem mRNA- und Omics-Technologien eingesetzt werden – Werkzeuge,
die sowohl bekannte Immunantworten analysieren als auch subtile Übergänge aufdecken,
welche die immunologische Heterogenität prägen. Ziel ist es, immunologische Signaturen
mittels genomweiter Datensätze zu identifizieren und das Verständnis der Immunregulation zu vertiefen. Die Arbeit umfasst drei Studien: zwei experimentelle Datensätze aus der
Dörner-Gruppe an der Charité – Universitätsmedizin Berlin und der Romagnani-Gruppe
am DRFZ Berlin sowie einen öffentlichen Datensatz. Die erste Studie (PMID: 38102122)
untersucht die Genexpression in Immunzellen nach anti-CD3-Stimulation und identifiziert
Interferon-stimulierte Gene (ISGs). Die zweite Studie beleuchtet die Reifung natürlicher
Killerzellen (NK-Zellen) und deren transkriptionelle Diversität während einer HCMV-
Infektion, wobei klonale Expansion und Gedächtnisbildung im Vordergrund stehen (PMID:
36289449). In der dritten Studie wird Einzelzell-RNA-Sequenzierung (scRNA-seq) genutzt,
um systemischen Lupus erythematodes (SLE) bei pädiatrischen Patienten zu untersuchen
– mit Einblicken in die Rolle von Monozyten und T-Zellen in der Krankheitsdynamik
(PMID: 32747814). Diese Studien beleuchten zelltypspezifische Immunaktivierung, Marker
autoimmuner Erkrankungen sowie die klinische Relevanz von ISGs, und sie erweitern
Einzelzellmethoden zur Identifikation verborgener Akteure der adaptiven Immunität. Ein
Schwerpunkt liegt auf der Erfassung dynamischer Immunprozesse durch Genexpressions-
Heterogenität. Durch die Abkehr von populationsbasierten Mittelwerten werden feine Regulationsmuster sichtbar, die durch Reifung und Aktivierungszustände geformt sind. Die
Studien zeigen, wie transkriptionelle Variabilität die Flexibilität und Reaktionsfähigkeit
von Immunzellen in autoimmunen und viralen Kontexten widerspiegelt. Zur Unterstützung
wurden rechnergestützte Methoden entwickelt, um Heterogenität zu quantifizieren, Differenzierungspfade zu rekonstruieren und Ligand-Rezeptor-Interaktionen über Immunzelltypen hinweg zu entschlüsseln. Diese Erkenntnisse vertiefen das Verständnis immunologischer Dynamiken und betonen die Rolle zellulärer Diversität in Krankheitsverläufen und
Therapieansätzen.What are the genomic footprints of immune activation? This dissertation addresses
that question by leveraging mRNA and Omics technologies, tools for dissecting known
immune responses and uncovering the subtle transitions that define immune heterogeneity.
The primary objective is to identify immunological signatures through genome-scale data
and to refine our understanding of immune regulation. It comprises three studies: two
experimental datasets from the Dörner group at Charité Universitätsmedizin Berlin and
the Romagnani group at DRFZ Berlin, and one public dataset. The first study (PMID:
38102122) investigates gene expression in immune cells after anti-CD3 stimulation, revealing Interferon-stimulated gene (ISG) responses. The second study focuses on natural
killer (NK) cell maturation and transcriptional diversity during human cytomegalovirus
(HCMV) infection, highlighting clonal expansion and memory formation. The dataset of
second study utilized in this study was obtained from PMID:36289449. In the third study,
single-cell RNA sequencing (scRNA-seq) was employed to investigate systemic lupus erythematosus (SLE) in pediatric patients. This analysis provided insights into the functional
roles of monocytes and T cells in modulating disease activity and influencing the dynamic
trajectory of SLE progression. The corresponding dataset of third study for this investigation was sourced from PMID: 32747814. Collectively, these studies explore immune
cell type-specific activation, autoimmune disease markers, and the clinical relevance of
ISG, while advancing single-cell methods to uncover hidden mediators of adaptive immunity. Special emphasis is placed on capturing the dynamic immune processes through the
lens of gene expression heterogeneity. By moving beyond population-level averages, this
work uncovers fine-grained regulatory patterns shaped by immune cell maturation, and
activation states. The studies reveal how transcriptional variability reflects the flexibility
and responsiveness of immune cells in both autoimmune and viral settings. To support
this, computational approaches were developed to quantify heterogeneity, trace differentiation trajectories, and decode ligand-receptor interactions across diverse immune cell types.
These insights deepen our understanding of immune response dynamics, emphasizing how
cellular diversity drives disease progression and guides therapeutic strategies

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.
