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

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
Error Reporting from a Nurse's Point of View: Results of a Survey in Nursing Homes and Hospitals

Das Gesundheitswesen. 2014;76(8-9):486-493.Zusammenfassung Ziel der Studie: Es sollten Erkenntnisse zu Fehlermeldungen aus Sicht von Pflegenden in stationaren Einrichtungen generiert werden. Methode: Eine schriftliche Befragung von in deutschen Pflegeheimen und Krankenhausern angestellten Pflegekraften wurde durchgefuhrt. Ergebnisse: Die 1100 Teilnehmer haben in einem halben Jahr durchschnittlich 1,9 Fehler gemeldet, im Pflegeheim mehr als im Krankenhaus. Der Anteil gemeldeter Fehler an allen Fehlern wird durchschnittlich auf 20,5% geschatzt. Einem Drittel der Pflegenden war nicht klar, welche Ereignisse gemeldet werden sollten. Jeweils uber 20% befurchteten disziplinarische Ma ss nahmen und gaben mangelnde Ruckmeldung zu Fehlermeldungen an. Die Ergebnisse sind statistisch unabhangig vom Vorhandensein eines Fehlermeldesystems, es gibt jedoch Hinweise auf organisatorische Vor- und arbeitsaufwandbezogene Nachteile systematischer Formen der Fehlermeldung. Auch zeigten sich Zusammenhange des Meldeverhaltens mit der Wahrnehmung auf die Organisation des konkreten Vorgangs der Fehlermeldung bezogener Faktoren. Schlussfolgerungen: Die inhaltliche Bestimmung von zu meldenden Fehlern und organisatorische und auf den Umgang mit Fehlern bezogene Hindernisse mussen angegangen werden, um die Melderate zu erhohen und Meldesysteme nutzbar zu machen. Abstract Aim of the Study: The aim of this study was to gain insight into the reporting of errors as perceived by nurses employed in inpatient health-care facilities. Method: A representative written survey of nurses working in German nursing homes and hospitals was conducted. Results: The 1100 respondents reported an average of 1.9 errors in the last half year, with nurses working in nursing homes reporting more errors than hospital-employed ones. They estimated that 20.5% of all errors are reported. One third of the participants did not know what events should be reported; more than 20% feared repercussions and mentioned a lack of feedback on error reports. Results are not statistically associated to the presence or absence of an error reporting system, but there are hints for organisational advantages and workload-related disadvantages of systematic forms of reporting. Reporting behaviour was also related to the perception of factors concerning the organisation of the actual reporting of errors. Conclusion: Defining reportable error events, organisational barriers to report errors and deficits in the dealing with errors and error reports have to be tackled to augment error reporting rates and profit from reporting systems
