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
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
Triglyceride-rich lipoproteins from type 2 diabetic patients : Effects on platelet activation and sphingolipidomic profile
No full textLe diabète de type 2 (DT2) est associé à plusieurs altérations du métabolisme lipidique ainsi qu’à l’incidence de complications cardiovasculaires. L’hypertriglycéridémie (HTG), caractérisée par une augmentation de la concentration des lipoprotéines riches en triglycérides (LRT), à jeun et en postprandial, ainsi que l’hyperactivité plaquettaire sont des facteurs de risque d’athérothrombose chez les patients DT2. La composition lipidomique des lipoprotéines peut également être modifiée dans un contexte de DT2, ce qui peut, par conséquent, affecter leur fonctionnalité. Notre objectif était de déterminer l’effet des LRT de patientes DT2 à jeun et suite à un repas contenant une matière grasse de source différente (végétale vs laitière) sur l’agrégation de plaquettes saines, ainsi que de déterminer la composition lipidomique, plus particulièrement en sphingolipides (SL), des LRT. D’abord, nous avons montré que les LRT de patients DT2 à jeun activent la voie de signalisation de l’acide arachidonique dans les plaquettes et augmentent leur concentration de thromboxane B2 (TxB2) et leur agrégation. Nous avons ensuite mis en place un protocole clinique en parallèle randomisé visant à étudier les effets des LRT de 30 patientes DT2 à jeun et 4h après l’ingestion d’un petit déjeuner contenant 20g de lipides de source laitière (beurre) ou végétale (pâte à tartiner cacao-noisette) sur les plaquettes et la composition en SL de ces lipoprotéines. Nous avons démontré que l’ingestion de 20g de lipides cause une augmentation des triglycérides et de l’ApoB-48 plasmatiques à 4h et modifie la composition en acides gras (AG) des LRT. De plus, les LRT isolés à jeun et en postprandial augmentent de manière similaire l’agrégation et la concentration de TxB2 plaquettaire. Concernant la composition en SL, la consommation d’une matière grasse riche en AG saturés a augmenté les concentrations en céramides (Cer) totales des LRT, plus précisément au niveau des espèces Cer 16:0, 22:0, 24:1 et 24:0, comparativement aux concentrations à jeun. La composition en SL des LRT de DT2 à jeun est également différente de celle de volontaires saines (augmentation des sphingomyélines, gangliosides GM3, de la sphingosine-1-phosphate et de la lyso sphingomyéline). Ces travaux mettent en évidence l’implication possible des LRT post-prandiales dans le développement de l’athérothrombose chez les patients DT2, ainsi que l’intérêt de l’étude du lipidome des lipoprotéines dans une optique de prévention des complications cardiovasculaires associées au DT2. Les mécanismes sous-tendant les effets de la composition en SL des LRT sur leur interaction avec les plaquettes restent à élucider.Type 2 diabetes (T2D) is associated with impaired lipid metabolism as well as higher incidence of cardiovascular complications. Hypertriglyceridemia (HTG), defined by an increase of triglyceride-rich lipoproteins (TGRL) in the fasting and postprandial states, and platelet hyperactivity are risk factors for atherothrombosis development in T2D individuals. Lipidomic composition of lipoproteins can also be modified in the context of T2D, and therefor affect their functionality. Our objective was to determine the effect of TGRL from T2D patients in the fasting state and after a breakfast containing a fat rich in saturated fatty acids (SFA) from a different source (dairy vs vegetal oil) on aggregation of healthy platelets, as well as assessing the lipidomic composition, especially of sphingolipids (SL), of TGRL. We first showed that TGRL from fasting T2D patients activate the arachidonic acid signaling pathway in platelets and increase their thromboxane B2 (TxB2) concentration and aggregation. We then designed a randomized parallel clinical trial that aimed to study the effect of TGRL from thirty T2D patients in fasting state and 4h after the ingestion of a breakfast containing 20g of lipids from dairy or vegetal oil on platelets, as well as the SL composition of the particles. We showed that the ingestion of 20g of saturated lipids induce an increase in plasma TG and ApoB-48 at 4h and modify the fatty acid (FA) composition of TGRL. Moreover, TGRL isolated in the fasting and postprandial state increase platelet aggregation and TxB2 concentration similarly. Regarding TGRL SL composition, consumption of a fat rich in SFA led to an increase in total ceramides (Cer) content in TGRL, more precisely of Cer16:0, 22:0, 24:1 and 24:0 molecular species. There are also differences in the SL composition of TGRL from fasting T2D patients compared to particles from controls (increase in sphingomyelins, GM3 gangliosides, sphingosine-1-phosphate and lyso sphingomyelin contents).This work highlights the probable implication of TGRL in atherothrombosis development in T2D patients, as well as the relevance of studying lipoproteins lipidome to identify new strategies for the prevention of cardiovascular complications associated with T2D. The mechanisms underlying the effects of TGRL SL composition and their interaction with platelets remain to be elucidated

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.
