Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Körperliche Aktivität bei ambulanten Patient*innen mit psychischen Erkrankungen: Prävalenz, motivationale und volitionale Determinanten als Ansatzpunkte zur Förderung körperlicher Aktivität
Full text linkKörperliche Aktivität hat einen positiven Einfluss auf die psychische Gesundheit und kann zur Prävention und Therapie psychischer Erkrankungen eingesetzt werden. Da nur eine Minderheit der Menschen mit psychischen Erkrankungen ein gesundheitsförderliches Ausmaß körperlicher Aktivität betreibt, scheint die Entwicklung von Interventionen, die Patient*innen dabei unterstützen, ihr Aktivitätsniveau zu steigern, dringend geboten. In den vorliegenden Arbeiten wird zunächst die Prävalenz körperlicher Aktivität bei ambulanten Patient*innen mit psychischen Erkrankungen und die Übereinstimmung von subjektiven und objektiven Messverfahren zur Erfassung körperlicher Aktivität bei dieser Population untersucht. Zudem wird untersucht, inwieweit sich das Motivations-Volitions-Modell (MoVo-Modell), das sozial-kognitive Determinanten körperlicher Aktivität zusammenfasst, auch auf Menschen mit psychischen Erkrankungen übertragen lässt. Daraufhin wird evaluiert, ob eine auf diesem Modell basierende psychologische Gruppenintervention zur Steigerung körperlicher Aktivität, die für Populationen ohne psychische Erkrankungen entwickelt wurde, auch bei ambulanten Patienten mit psychischen Erkrankungen effektiv ist. Zudem wird evaluiert, ob körperliche Aktivität unmittelbar vor der Exposition bei der Verhaltenstherapie der Panikstörung und Agoraphobie eine wirksame Kombinationstherapie darstellt. Die Ergebnisse zeigen, konsistent mit dem aktuellen Forschungsstand, dass auch in unserer Stichprobe nur eine Minderheit der Menschen mit psychischen Erkrankungen ein ausreichendes Maß körperlicher Aktivität betreibt. Bezüglich der Messbarkeit körperlicher Aktivität zeigt sich eine gute Übereinstimmung von subjektiven und objektiven Messverfahren für globale Gruppenmittelwerte. Bei der Messung auf Individualebene oder der Differenzierung in verschiedene Intensitätslevel zeigen sich jedoch deutlich Differenzen zwischen subjektiver und objektiver Messung, sodass sich die Kombination beider Messverfahren für zukünftige Studien, in denen die solche Parameter von Interesse sind, dringend empfiehlt. Zudem ergeben sich Hinweise darauf, dass das MoVo-Modell grundsätzlich auch bei Menschen mit psychischen Erkrankungen Anwendung finden kann. Bezüglich der darauf aufbauenden Intervention zur Steigerung körperlicher Aktivität zeigt sich, dass dieses auch bei ambulanten Patienten mit psychischen Erkrankungen wirksam ist. Bezüglich der Rolle körperlicher Aktivität zur Kombination mit expositionsbasierter Verhaltenstherapie bei Panikstörung und Agoraphobie zeigen sich erste Hinweise auf eine mögliche Reduktion der Wirklatenz der Verhaltenstherapie durch körperliche Aktivität unmittelbar vor der Exposition. Zusammengefasst zeigt sich, dass viele Menschen mit psychischen Erkrankungen die Empfehlungen bezüglich gesundheitsförderlicher Aktivität nicht erfüllen, dass die untersuchte Intervention effektiv ist, den Anteil dieser zu steigern und dass körperliche Aktivität effektiv sein könnte, um die Wirklatenz expositionsbasierter Verhaltenstherapie zu reduzieren.Physical activity has a positive effect on mental health and can be used in prevention and treatment of mental disorders. As only a minority of patients with mental disorders shows a health beneficial level of physical activity, there is a strong need for the development of interventions that support patients to increase their level of physical activity. The present work examines the prevalence of physical activity and the congruence of subjective and objective measurements of physical activity in outpatients with mental disorders. It further examines if the Motivation-Volition-Model (MoVo-Model), that summarizes social-cognitive determinants of physical activity, is suitable for patients with mental disorders as well. A psychological group intervention to increase physical activity, that is based on this model and was developed for populations without mental disorders, is tested on its effectiveness in patients with mental disorders. Additionally, it is investigated, if physical activity is an effective combination therapy with cognitive behavioural therapy, when applied directly prior to in-vivo exposure in patients with agoraphobia and panic disorder. Consistently with other research, our findings show that only a minority of patients with mental disorders shows a sufficient level of physical activity. Concerning the measurement of physical activity, there is a good accordance of subjective and objective measurement for global group averages. When it comes to measurement on individual-level or the differentiation into different intensity levels, there are noticeable differences between subjective and objective measurement. Therefore, the combination of both forms of measurement is strongly advised for studies where these parameters are of interest. Furthermore, from the present work arises evidence that the MoVo-Model is suitable for patients with mental disorders as well. The examined group intervention was effective in increasing physical activity in outpatients with mental disorders. Concerning the role of physical activity as a combination therapy with exposure based cognitive behavioural therapy in agoraphobia and panic disorder, from the present work arises some evidence that physical activity prior to exposure might accelerate the effect of cognitive behavioural therapy. Summarized the present work shows that a large proportion of patients with mental diseases does not reach the recommendations for health beneficial physical activity, that the used intervention is effective in increasing this proportion and that physical activity might be effective to accelerate the effect of exposure based cognitive behavioural therapy
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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.
