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
Kurt R. Weiss
No full textDr. Kurt R. Weiss is an associate professor in the University of Pittsburgh Department of Orthopaedic Surgery, Division of Musculoskeletal Oncology. He has joint appointments in Surgical Oncology and Pathology. He serves as an Advisory Dean for the University of Pittsburgh School of Medicine and as Vice Chair of Translational Research for his Department. His research career began as an undergraduate student at Notre Dame when he worked in the Ferguson Laboratory with Dr. Christopher Evans. During medical school at Jefferson Medical College, he performed a summer research internship with Dr. Eugenie Kleinerman at the University of Texas MD Anderson Cancer Center in Houston. Between his second and third years of medical school he participated in the Howard Hughes Medical Institute/National Institutes of Health Research Scholars Program where he worked in Dr. Lee Helman’s Laboratory in the National Cancer Institute (NCI) Pediatric Oncology Branch. During residency he performed original osteosarcoma research during his lab year with Dr. Johnny Huard. After his fellowship in Musculoskeletal Oncology at the University of Toronto with Drs. Jay Wunder and Peter Ferguson, Dr. Weiss was recruited back to Pittsburgh by his Chairman, Dr. Freddie Fu, as faculty and started his own Lab.
The Musculoskeletal Oncology Laboratory (MOL) is focused on sarcoma metastatic potential. Dr. Weiss’s team of PhD collaborators, residents, medical students, undergraduate students, and technicians perform basic and translational sarcoma research experiments. Much of this work is accomplished with samples from the Musculoskeletal Oncology Tumor Registry and Tissue Bank (MOTOR) that Dr. Weiss and his clinical partners established in 2012. The MOTOR now holds over 16,000 unique samples from over 600 sarcoma patients with clinical annotation, making it one of the largest sarcoma tissue repositories in the country. This resource provides vital biological reagents for both intramural and extramural sarcoma investigators who collaborate with the MOL.
Dr. Weiss is an author on over 80 peer-reviewed publications. He recently finished his term as Research Committee Chair for the Musculoskeletal Tumor Society, the largest professional society for musculoskeletal oncology surgeons on the continent of North America. He is on the Mentorship Committee for the Connective Tissue Oncology Society, for which he has also served on the Board of Directors. He was recently named to the Scientific Steering Committee of the Sarcoma Alliance for Research through Collaboration (SARC), the largest private supporter of sarcoma clinical trials in the world. He has taught at the Orthopedic Research Society grant writing course for many years. Dr. Weiss is a regular reviewer for NCI grant applications and was on the inaugural Programmatic Panel for the Department of Defense Rare Cancers Research Program. His funding sources have included K08 and R21 awards from the NCI as well as the support of numerous foundations including the Orthopedic Research and Education Foundation and the Connective Tissue Oncology Society. Dr. Weiss is a founding member of the Pittsburgh Cure Sarcoma (PCS) patient advocacy group, as well as the Pittsburgh Sarcoma Research Collaborative (PSaRC).https://openworks.mdanderson.org/kleinermanbios/1004/thumbnail.jp
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
