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
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
Entwicklung und Evaluation eines Interventionskonzeptes zur Prävention kardiovaskulärer Risikoparameter bei Beschäftigten in KMU
Get PDFBetriebliche Gesundheitsförderung: Entwicklung und Evaluation eines Interventionskonzeptes zur Prävention kardiovaskulärer Risikoparameter bei Beschäftigten in KMU
Einleitung: Gesellschaftliche Veränderungen der vergangenen Jahrzehnte begünstigen durch Inaktivität und hyperkalorische Ernährung einen Lebensstil, der die steigenden Übergewichtsprävalenzen und deren Komorbiditätenin der Erwerbsbevölkerung erklärt. Unternehmen werden zukünftig für den Erhalt der Leistungsfähigkeit ihrer Beschäftigten verstärkt in wirkungsvolle und adressatengerechte Präventionsmaßnahmen investieren müssen. Diesbezüglich wurde im Rahmen der vorliegenden Studie ein Interventionskonzept zur Prävention kardiovaskulärer Risikoparameter bei Beschäftigten in klein- und mittelständischen Unternehmen (KMU) entwickelt und umgesetzt sowie die Effekte der Interventionen auf kardiovaskuläre Risikoparameter und das Gesundheits-verhalten untersucht.
Methodik: Das 14-wöchige Interventionskonzept berücksichtigte verhaltensmodifizierende, bewegungs- und ernährungsbasierte Inhalte. Der Untersuchungsansatz umfasste drei Messzeit-punkte (t0 Eingangsanalyse, t1 nach der 14-wöchigen Intervention, t2 nach der 24-wöchigen Vernetzungsphase) mit Erhebung kardiovaskulärer Risikoparameter (anthropometrische Daten, Lipidprofil, Blutdruck) und den Einsatz eines Fragebogens zum Ernährungs- und Bewegungsverhalten bei 170 Beschäftigten in 16 KMU. Davon bildeten 120 Beschäftigte die Interventionsgruppe (IG) und 50 Beschäftigte die Vergleichsgruppe (VG). Das Konzept umfasste individuelle Beratungsgespräche, Seminare zum Thema „Gesunde Ernährung“ und „Barrieremanagement“ sowie angeleitete Bewegungseinheiten. Innerhalb der IG nahmen die Treatment-Komplett-Teilnehmer (n=66) an allen Interventionen teil, 44 entschieden sich nur für eine Maßnahme und 10 Teilnehmer nahmen, trotz individueller Beratung, an keiner Intervention teil. Durch die anschließende Vernetzung der Beschäftigten zu regionalen Gesundheitsanbietern konnte eine Verstetigung der Effekte erreicht werden.
Ergebnisse: Die Ergebnisse zeigen, dass sich das kardiovaskuläre Risikoprofil bei den Beschäftigten der IG durch das Präventionskonzept signifikant reduziert hat. Neben einer signifikanten Reduzierung des Körpergewichts,des BMIs, des Taillenumfangsund des prozentualen Körperfettgehaltes nach der Intervention (t1)und bis zur Abschlussuntersuchung (t2) konnten auch signifikante Veränderungen beim Gesamt-C und beim LDL-C nach der Intervention (t1) sowie beim HDL-C und systolischen Blutdruck bis zur Abschlussuntersuchung (t2) nachgewiesen werden. In Bezug auf Veränderungen beim Gesundheitsverhalten belegte die Fragebogenauswertung nur in der IG signifikante Effekte hinsichtlich einer Steigerung der körperlichen Aktivität und eines gesunden Ernährungsverhaltens unter anderem durch eine Steigerung des Obst- und Gemüseverzehrs zu t1 und t2. Deutlich wird auch, dass sich die stärksten Effekte in allen Parametern für die Treatment-Komplett-Teilnehmer zeigten, diean den ernährungs- bzw. verhaltensmodifizierenden Interventionen und den angeleiteten Bewegungseinheiten teilnahmen. In anderen Treatmentgruppen, die isoliert nur an den Bewegungs- oder Ernährungsinterventionen teilnahmen, konnten keine Effekte auf die beschriebenen kardiovaskulären Risikoparameter und auf das Gesundheitsverhalten ermittelt werden.
Diskussion: Aus den Ergebnissen der Studie lässt sich ableiten, dass für betriebliche Gesundheits-projekte, die auf die Prävention kardiovaskulärer Risikoparameter abzielen, eine Kombination aus Maßnahmen zur Ernährungsumstellung und zur Steigerung der körperlichen Aktivität, ergänzt durch verhaltensmodifizierende Interventionen, zielführend sind. Zukünftige Präventionskonzepte im betrieblichen Setting sollten über die Gestaltung bewegungsförderlicher Arbeitswelten und eine gesundheitsbewusste Verpflegung sowie die gezielte Nutzung des sozialen Arbeitsumfeldes gesundheitsorientierte Verhaltensänderungen auf Beschäftigtenebene unterstützen. Diese Interventionen auf der Verhältnisebene und die Vernetzung zu regionalen Gesundheitsanbietern können einen entscheidenden Beitrag zur Verstetigung der Effekte leisten.
Health promotion: Development and evaluation of a novel intervention strategy for the prevention of cardiovascular risk factors in SME employees
Introduction: Several lifestyle changes in the working population occurred in the recent decades, leading to increased prevalence of obesity and its associated comorbidities, such as cardiovascular disease. Besides obesity, physical inactivity, a high blood pressure, increased serum cholesterol and triglyceride level represent cardiovascular risk factors. To ensure performance and health of employees, companies will have to invest in the development of effective and feasible prevention strategies in the future. Therefore, aim of the present thesis was the development and evaluation of an effective and feasible intervention strategy to prevent the prevalence of cardiovascular risk factors in employees of small and medium-sized enterprises (SMEs).
Methods: Several cardiovascular risk factors were assessed in 170 employees from 16 SMEs. Among those 120 employees underwent a 14-week lifestyle intervention (Intervention group, IG), including individual coaching, group seminars on the subject of “healthy nutrition” and “barrier management” as well as supervised exercise units. Within the IG, 66 subjects were able to follow the complete intervention program (complete intervention group, CIG), while 54 subjectspartly participated in the intervention. Cardiovascular risk factors (anthropometric data, lipid profile, blood pressure) were assessed at three different time-points (t0: baseline, t1: after the 14-week intervention, t2: after a 24-week follow-up period).Moreover, a lifestyle questionnaire was conducted at t0, t1 and t2 to report physical activity and nutritional behaviour. During the 24-week follow up period participants were cross-connected with regional health care providers.
Results: Several cardiovascular risk factors were significantly reduced in the IG after the multidisciplinary intervention compared to baseline. Body weight, BMI, waist circumference and percentage of body fat were significantly reduced after the 14-week intervention period (t1) as well as the follow-up (t2). In addition to these anthropometric parameters also clinical parameters were improved at t1 and t2. In line, decreased levels of total cholesterol and LDL-cholesterol at t1, increased HDL-cholesterol and decreasedsystolic blood pressure were observed in the IG at t2 compared to t0. Furthermore, the lifestyle questionnaire revealed significant changes in behaviour among the IG, but not in the control group. Thus, physical activity was significantly increased after the intervention (t1) and follow-up (t2) and aspects of nutritional behaviour were improved, such as increased intake of fruits and vegetables. For all parameters, the strongest effects were observed in the CIG, who participated in the full intervention program. Subjects who did not follow the complete intervention program and only partly participated showed no improvements of the assessed anthropometric as well as clinical cardiovascular risk factors.
Discussion: The present study indicates that a combination of nutritional as well as physical interventions is necessary to prevent and improve cardiovascular risk factors. Moreover, behavioural coaching is beneficial for long-term prevention and compliance with the lifestyle intervention. In conclusion, effective work place-associated prevention strategies should comprise measures increasing physical activity and improving nutrition, such as the offer of healthy catering at work. Besides, a targeted use of the social work environment can support health-orientedbehaviour. These interventions focusing on health-promoting working conditionsand the cross-connection with regional health care providerscan crucially contribute to a perpetuation of the effects

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.
