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
Einfluss der mütterlichen Bindung auf die Entwicklung einer postpartalen Depression : MATER-Studie
Get PDFBackground and intention Postpartum depression is one of the most common diseases of the puerperium with extensive psychological, physical and social consequences for both mother and child. The aim of the MATER-study (MATER: Maternal Attachment in Erlangen) was to assess predictors for postpartum depression and whether or not there is a connection to other more subtile phenomena such as pregnancy disorders. For this purpose mother-infant and mother-partner attachment, delivery mode and birth experience, planned breast feeding and planned start of work after birth were examined. In addition, the influence on the mothers’ state of mind and the development of postpartum depression were tested. Methods The prospective study involved interviewing 190 nulli parous women between the 26th and 40th week of gestation by means of standardized questionnaires (Fragebogen zur Schwangerschaft, Edinburgh Postnatal Depression Scale, Relationship Scales Questionnaire, Fragebogen zur Partnerbeziehung, Test für emotionale Kompetenz, Fragebogen zur emotionalen Kompetenz, Vorgeburtliche Bindung zwischen Mutter und Kind, Fragebogen zum Schema vom Kind). The aggregated questionnaires were handed over during the notice of intention to attend the birth at the Universitäts-Perinatalzentrum-Franken in the obstetric clinic of the Universitity Erlangen to our probands which met the citeria of the MATER-study. The probands completed the questionnaire at home. Furthermore the Adult Attachment Projective, a test for evaluating the type of maternal bonding, was conducted with the included probands. Also, the women were interviewed by telephone three weeks and six months postpartum by means of EPDS regarding symptoms of postpartum depression, diagnosis and therapy. Obstetric information about pregnancy, delivery and puerperium was collected from patient records. Data was analysed with the statistics software package SPSS 17.0 for Windows (SPSS Inc., Chicago, Il, USA). Results and observations The evaluation of questionnaires Maternal Attachment Scale and Fragebogen zum Schema vom Kind showed significant coherency with low EPDS-scores. The prepartum attachment serves as a predictor for less pregnancy disorders and fewer development of postpartum depression. In addition, the evaluation of questionnaire Fragebogen zur Partnerbeziehung showed significant coherency of less pregnancy disorders. Subsequently it might be inferred that a well defined mother-child-attachment has a positive influence on the postpartum depression rate. In accordance with FRAMES (Franconian Maternal Health Evaluation Study), the MATER study indicated a connection between lost feeling of control during delivery and higher EPDS-scores. Women after both assisted vaginal delivery and emergency caesarean section showed the highest values at three weeks and six months postpartum. A connection between planned breast feeding and planned start of work after birth could not be verified. Practical conclusions The MATER-study illustrates that the development of postpartum depressions is influenced by the maternal attachment style. The maternal attachment style is not merely influenced by mother-infant attachment, but a multi-faceted point of view including the partner relationship and the social background has to be taken into account. The overall birth experience and the feeling of being in control during delivery might have a significant impact on the development of postpartum depression.Hintergrund und Ziele Die postpartale Depression (PPD) zählt zu den häufigsten Erkrankungen des Wochenbettes und hat weitreichende psychische, physische als auch soziale Folgen für die Mutter und das Kind. Ziel der MATER-Studie (MATER: Maternal Attachment in Erlangen) war es verschiedene Prädiktoren für die Entwicklung einer postpartalen Depression und ihren Zusammenhang zu Schwangerschaftsbeschwerden darzustellen. Hierfür wurden die Aspekte Mutter-Kind-Bindung, Partner-Bindung, Geburtsmodus und -erleben, geplantes Stillverhalten und Arbeitsbeginn nach der Schwangerschaft untersucht und ihr Einfluss auf das mütterliche Befinden und auf die Entwicklung einer PPD hin geprüft. Methoden Die klinisch prospektive Studie umfasste die Befragung von 190 Erstgravida zwischen der 26. und der 40. SSW mittels standardisierter Fragebögen (Fragebogen zur Schwangerschaft, Edinburgh Postnatal Depression Scale, Relationship Scales Questionnaire, Fragebogen zur Partnerbeziehung, Test für emotionale Kompetenz, Fragebogen zur emotionalen Kompetenz, Vorgeburtliche Bindung zwischen Mutter und Kind, Fragebogen zum Schema vom Kind). Der aggregierte Fragebogen wurde bei der Voranmeldung zur Geburt im Universitäts-Perinatalzentrum-Franken der Frauenklinik des Universitätsklinikums Erlangen den Probandinnen überlassen. Diese wurden nach bestimmten Ein- und Ausschlusskriterien ausgewählt und sollten den Fragebogen zu Hause bearbeiten. Außerdem wurde, bei Einschluß in die Studie das Adult Attachment Projective durchgeführt, ein Test zur Bestimmung des mütterlichen Bindungstyps. Zusätzlich wurden die Probandinnen drei Wochen postpartum und sechs Monate postpartum mittels Edinburgh Postnatal Depression Scale telefonisch zu Symptomen einer PPD befragt. Geburtshilfliche Daten zu Schwangerschaft, Geburt und Wochenbett wurden der Patientenakte entnommen. Die statistische Auswertung wurde mit dem Softwarepaket SPSS 17.0 für Windows (SPSS Inc., Chicago, Il, USA) durchgeführt. Ergebnisse und Beobachtungen Die Auswertung der Fragebögen Maternal Attachment Scale und Fragebogen zum Schema vom Kind zeigte einen signifikanten Zusammenhang mit niedrigen Werten der EPDS. Die pränatale Bindung zum Ungeborenen fungiert also als Prädiktor für geringe Schwangerschaftsbeschwerden und selteneres Auftreten einer postpartalen Depressivität. Die Auswertung des Fragebogen zur Partnerbeziehung zeigte einen signifikanten Zusammenhang mit geringen Schwangerschaftsbeschwerden. Daraus lässt sich ableiten, dass eine gute Mutter-Partner-Bindung in zweiter Instanz die postpartale Depressivitäts-Rate senken kann. Wie in einer Vorgängerstudie unserer Arbeitsgruppe FRAMES (Franconian Maternal Health Evaluation Study) konnte ein Zusammenhang zwischen einem Kontrollverlust während des Geburtsvorgangs und einem erhöhten EPDS-Score dargelegt werden. Frauen, die vaginal-operativ oder per Notsectio entbanden, zeigten zu den Erhebungszeitpunkten drei Wochen und sechs Monate nach der Entbindung erhöhte EPDS Werte. Ein Zusammenhang zwischen geplantem Stillverhalten und geplantem Wiedereinstieg in die Arbeit und der Mutter-Kind-Bindung konnte nicht gezeigt werden. Praktische Schlussfolgerungen Die MATER-Studie zeigt auf, dass das Entstehen einer postpartalen Depressivität maßgeblich durch den mütterlichen Bindungstyp bedingt wird. Allerdings darf dies nicht eindimensional auf die Mutter-Kind-Bindung bezogen werden, sondern muss als multifaktorielles Geschehen gesehen werden, in dem auch der Partner und das Umfeld eine Rolle spielen. Besonders hervorzuheben ist, dass der Kontrollverlust unter der Geburt von großem Einfluss auf die Entwicklung einer postpartalen Depressivität sein kann, nicht aber der Geburtsmodus an sich
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

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.
