    The 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

    YouTube als emanzipatorisches Aufklärungs- und Informationsmedium für Jugendliche? : Eine qualitative Untersuchung zu Chancen und Grenzen entlang von Expert*inneninterviews

    WhatsApp, Instagram, YouTube, Snapchat - die Neuen Medien sind aus dem Alltag Jugendlicher nicht mehr wegzudenken. Nach aktuellem Forschungsstand ist das Internet nicht nur ein beliebtes Medium zu Kommunikations- und Unterhaltungszwecken, sondern dient auch im Bereich der Sexualität als Hauptinformationsquelle. Der Wunsch nach sexualitätsbezogenen Informationen in der Adoleszenz ist groß, weshalb sich Jugendliche der Quellen bedienen, die für sie zugänglich sind. Hier spielt vor allem die Videoplattform YouTube eine bedeutende Rolle: Laut der aktuellen JIM-Studie (2018) ist sie mit 70% bei den Jungen und mit 55% bei den Mädchen die populärste Onlineplattform. Auch bezüglich der Informationssuche und Recherche im Internet hat sich YouTube als relevante Quelle etabliert: Zwei Drittel der Befragten gaben an, YouTube mehrmals pro Woche zu Informationszwecken zu nutzen und so ist die Plattform aktuell, nach Google und sogar vor Wikipedia, die zweitwichtigste Webseite zur Recherche von informationsorientierten Themen. Anhand der genannten Ergebnisse ist ersichtlich, welch hohen Stellenwert diese Videoplattform, nicht zuletzt durch die bisher kostenfreie Nutzung, im Alltag Jugendlicher hat. Durch die rasante Entwicklung der Neuen Medien ist den Nutzer*innen dadurch ein schnellerer sowie leichterer und demzufolge bequemerer Zugang zu Informationen möglich. Hinzu kommt, dass der Aufklärungsunterricht in der Schule die Wissenslücken Jugendlicher nicht ausreichend schließen und ihre wichtigen Fragen nicht beantworten kann, weshalb der Informations- und Wissensaustausch einerseits über die Neuen Medien und andererseits bevorzugt über Peers stattfindet. Jedoch bleibt fraglich, woher diese ihr Wissen beziehen und wie die Qualität der Informationen zu bewerten ist. Vor diesem Hintergrund sieht die Autorin dieser Arbeit eine große Verantwortung für sexualpädagogische Fachkräfte, die in der außerschulischen Aufklärungs- und sexuellen Bildungsarbeit tätig sind. Ferner ist zu konstatieren, dass eine notwendige Aufgabe darin besteht, sich mit aktuellen Themen rund um Sexualität und Medien auseinanderzusetzen und zeitgemäße sowie zielgruppenorientierte Angebote für Jugendliche zu schaffen und Einblicke in die (digitale) Lebenswelt der Jugendlichen zu erhalten, um somit auf deren individuelle Bedürfnisse eingehen und auf ihre sexualitäts- sowie medienbezogenen Fragen adäquat reagieren zu können

    Variations on the Author

    “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

    We 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 PDF
    We 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

    Prospective evaluation of sexual health following radical cystectomy due to bladder cancer.

    BACKGROUND There is a lack of data concerning sexual health following open radical cystectomy (RC), especially in elderly patients and women. AIM To describe sexual health and its impact on general health as well as survival in patients undergoing standard open RC for the treatment of bladder cancer (BC). Due to limited data, subgroup analysis for elderly patients and women was performed. METHODS A prospective noninterventional clinical study was performed evaluating sexual health in RC with any kind of urinary diversion due to BC with a follow-up of 12 months after RC. The study was approved by the local ethics review board (A 2021-0175) and was registered at the German Clinical Trial Register (DRKS00026255). Assessment of sexual health was done with the following validated questionnaires: EORTC QLQ-C30 (for quality of life; European Organisation for Research and Treatment of Cancer), EORTC SH22 (for sexual health), and IIEF-5 (5-item International Index of Erectile Function). OUTCOMES The standard measurements of EORTC QLQ-C30, EORTC SH22, and IIEF-5 as well as overall survival. RESULTS Thirty-two patients participated in the study with a mean age of 71.5 years (SD, 9.7): 25 (78.1%) were male and 7 (21.9%) were female. Overall there is a heterogenic picture for sexual health in the study population, but sexual satisfaction is significantly higher prior to surgery while the importance of a sex life stays high and stable. Interestingly, the general health score is significantly correlated to sexual satisfaction (Pearson's correlation; r = 0.522, P = .002) preoperatively but not following surgery: r = 0.103 (P = .665) after 3 months, r = 0.478 (P = .052) after 6 months, r = 0.276 (P = .302) after 9 months, and r = 0.337 (P = .202) after 12 months. The importance of a sex life is still essential for the patients, especially when recovering from RC; nearly the same can be reported for elderly patients. Unfortunately, the data for women are too limited to report robust results. CLINICAL IMPLICATIONS Evaluation, advice, and monitoring of sexual health must be integrated into clinical practice, particularly in women. STRENGTHS AND LIMITATIONS At least to our knowledge, this is the first systematic prospective evaluation of sexual health in patients with BC receiving RC. Due to the small sample size, there is a risk of selection bias. CONCLUSION Sexual health is important for patients with BC receiving RC, and it is an essential part of quality of life, especially in elderly patients

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
