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

Kerndokumentation für Palliativstationen - Strukturqualität und Ergebnisqualität
No full textSeit 1996 wird in Zusammenarbeit mit der Deutschen Gesellschaft für Palliativmedizin und der Deutschen Krebsgesellschaft eine Kerndokumentation für Palliativstationen entwickelt, in der personen-, krankheits- und therapiebezogene Daten zum Aufnahmezeitpunkt und nach Behandlungsende erfasst werden können. Die Kerndokumentation wurde in zwei Phasen durchgeführt und auf Praktikabilität und Aussagekraft überprüft; in dieser Studie werden Daten zur Struktur- und Ergebnisqualität aus der zweiten Erprobungsphase vorgestellt. Von den 65 Palliativstationen, die im Jahr 2000 in Deutschland bestanden, nahmen 44 Stationen mit insgesamt 72,2 % der Palliativbetten in Deutschland an der Untersuchung teil. 47,9 % der 1087 Patienten wurden von zu Hause auf die Palliativstation eingewiesen. Von diesen 1087 Patienten konnten 45,6 % nach der stationären Behandlung wieder nach Hause entlassen werden. Der Anteil der verstorbenen Patienten lag bei den aus einem anderen Krankenhaus (59,0 %) oder einer anderen Abteilung (51,7 %) übernommenen Patienten deutlich höher als bei den von zu Hause aufgenommenen Patienten (42,1 %). Für die Vorbereitung der häuslichen Versorgung, die psychische Stabilität und Zufriedenheit, vor allem aber für die Schmerztherapie und Symptomkontrolle wurden gute Verbesserungen während der stationären Therapie dokumentiert. Pflegerische Situation und Allgemeinzustand verschlechterten sich demgegenüber während der stationären Behandlung. Die Ergebnisqualität wies weder für die gesamte Patientengruppe noch für die Gruppe der entlassenen Patienten einen Zusammenhang mit der Strukturqualität der Palliativstationen auf. So konnten weder für die Stationen mit einem höheren Schlüssel für die Krankenpflegestellen pro Palliativbett, noch für die Stationen mit eigenen Psychologen, Physiotherapeuten, Seelsorgern oder Sozialarbeitern signifikante Unterschiede in der Ergebnisqualität gezeigt werden. Die vorgestellten Ergebnisse verdeutlichen, dass für die Qualitätssicherung in der Palliativmedizin eigene Instrumente geschaffen werden müssen, die den besonderen Anforderungen an diese Fachrichtung genügen. Als Voraussetzung dafür ist es notwendig, den Stellenwert der einzelnen Elemente der Palliativmedizin wie Symptomkontrolle oder Kommunikation mit Patienten und Angehörigen zu definieren.A core documentation for palliative care units has been developed in co-operation with the German Association for Palliative Medicine and the German Cancer Society since 1996. This core documentation includes patient-, disease- and therapy-related information at the time of admission and discharge. The core documentation has been evaluated in two phases, data from the second phase related to structural quality and outcome are presented in this study. 44 of the 65 palliative care units existing in Germany in 2000 participated in the study, representing 72,2 % of the palliative care beds available in Germany. Nearly half of the 1087 patients (47,9 %) were admitted from home care to the palliative care units. Of these patients, 45,6 % returned to home care after inpatient treatment. The percentage of patients who died in the palliative care wards was higher for patients referred from another hospital (59,0 %) or from other departments of the own hospital (51,7 %) than from patients admitted from the home care setting (42,1 %). Relief of pain and symptom control were increased during inpatient treatment, as were level of care available at home, psychological stability and patient satisfaction, but to a lesser degree. Level of care needed and performance status decreased during inpatient treatment. Outcome parameters showed no relationship with the structural quality of the palliative care unit for the whole group of patients as well as for patients discharged. No significant differences were seen for units with higher ratios of nurses per bed or for units providing chaplains, psychologists, physiotherapists or social workers. The results of this study emphasise that specific instruments have to be developed for quality assurance in palliative medicine. The values assigned to each of the different domains of palliative care such as symptom control or communication with patients and relatives should be defined as a prerequisite for the development of these instruments
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
