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
The role of intra-ovarian factors in the regulation of follicular death and survival, and management of ovarian lifespan
No full textLiving organisms are characterized by their ability to reproduce. History has witnessed the importance given by human societies to the process of procreation. Nevertheless, the people of yore were not capable of comprehending the intricate processes underlying such an important function and attributed it to divine intervention. While fertility and procreation formed the very basis of the dogmas of early life, failure to conceive was perceived as the ultimate curse. Light was thrown on the science of reproductive processes during the sixteenth century. With time, our knowledge has managed to permeate profoundly to understand the process of reproduction, but infertility continues to remain a major and painful life crisis that provides lifelong scarring with significant psychological, economic, demographic and medical effects. The inability to conceive strikes out at the very base of human identity, rapidly plummeting the couple downhill emotional turmoil; needless to say however, the women are subjected to more emotional damage than their male counterparts. Despite all the breakthroughs in the empowerment of women, a woman is still considered incomplete if she cannot become a mother. In humans, reproduction is much the same as for other mammals where they employ in-vivo fertilization that depends on the integrated action of hormones, the nervous system, and the reproductive system. It involves production and maturation of male and female gametes by the gonads, fertilization of the oocyte by spermatozoa, implantation in the uterus, and beginning of a new life. For the woman this demands regular and reliable ovarian cycles centrally featured by ovarian follicle development leading to ovulation in concert with production of estrogen and progesterone under the chief controlling influence of pulsatile gonadotropin secretion from pituitary. For both sexes, the gonads, ovaries in female and testes in male, serve the gametogenic and key endocrine functions, while the hypothalamo-pituitary unit governs the whole process. Diseases interfering with any of these components adversely affect the ability of a couple to conceive. Infertility can be defined as a failure to become pregnant in a period of 12 months for patients under the age of 35 and failure to conceive in a 6 month period for the over 35 age group. Causes of infertility can be found in about 90% of the cases, but despite extensive investigations, about 10% of couples will never know why they cannot conceive.Male or female infertility each accounts for about 30% to 40% of cases. Other cases are due to a combination of male and female factors or to unknown causes. Over the past several decades, demographic and socioeconomic trends have resulted in an increase in the absolute number of women seeking pregnancy in their late 30’s and early to mid 40’s. Compared to other major organ systems the female reproductive system ages to the point of failure at a relatively young age. Although the average age of menopause is 51, peak efficiency in the female reproductive system occurs in the early 20’s with a steady decline thereafter. There is a gradual loss of fertility as a function of female age with the rate of decline in fertility becoming more dramatic after the age of 35. This decline in fertility occurs in spite of the fact that women generally maintain regular, ovulatory menstrual cycles well into the fifth decade. A significant number of women in the advance age group seek evaluation and treatment for infertility. The general consensus is that the ovarian aging is accompanied not only by remarkable decline in the ovarian follicle pool but also by an increase in low-quality oocytes that are not competent enough for fertilization and further development. There are several lines of evidence documenting that oocyte quality determines its fertilization and subsequent development potential, and abnormalities of the oocyte act as the predominant cause of age-associated infertility. Clinical research over the last three decades almost exclusively concentrated on the ovarian hyperstimulation and in vitro fertilization. A number of recent documents raised suspicion over the classical concept of ‘oocyte aging’. Indirect evidence are there to support the view that the so called ‘aged oocytes’ collected from ‘aged ovary’ may be rendered fertile if cultured in ‘suitable’ conditions. This forms the basis of the present dissertation that endeavors understanding the ovarian milieu with respect to size of follicular reserve that, in fact, differentiates the ‘healthy’ and ‘aged’ ovary. The objective is to identify the missing link between declining follicular reserve and loss of oocyte quality, which may perhaps open a new frontier in the management of infertility

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.
