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
Социодемографски профил и мутации за тромбофилија кај жени со неуспешна in vitro фертилизација – почетни резултати од студија на случај и контрола
Get PDFThere are many factors for in vitro fertilization (IVF) failure, and hereditary thrombophilia has been mentioned as one of them in the last few years. Thrombophilia is a condition of predisposition to thromboembolism. The aim of the study was to evaluate the sociodemographic characteristics and to examine the representation of thrombophilic mutations in women with IVF failure. Material and methods: In a retrospective-prospective case-control study we evaluated 52 women, divided in two groups. Twenty-twowomen with at least three IVF failures were included in the examined group (EG). Thirty women, age matched, who gave birth to at least one healthy child without obstetric complications were included in the control group. Presence of gene mutations for factor II Prothrombin (G20210A), factor V Leiden (FVL) and methylentetrahydrofolate reductase (MTHFR C677T) was examined in both groups. Sociodemographic data, data from personal, family and obstetric anamnesis was collected with standard questionnaire. Results: Representation of nationality in both groups roughly corresponds to the national structure in Republic of Macedonia. In both groups the most prevalent age was from 30 to 34 years (40% in the CG and 50% in the EG). According to the degree of education, homogeneity between the two groups was registered. In most of the EG, MTHFR heterozygous was 63.6% vs. 56.7% in the CG, followed by the FV Leiden heterozygous with 13.6% vs. 3.3% in the CG, MTHFR homozygous with 9.1% vs. 6.7% in CG, factor II Prothrombin (G20210A) heterozygous with 4.5% vs. 6.7 in CG. 72.7% of women in the EG and 60% in the CG had one thrombophilic mutation, and 9.1% of women in EG and 6.7% in CG had two thrombophilic mutations. 18.2% of women in EG and 33.3% in CG did not have any mutations. Conclusion: The sociodemographic profile of women with IVF failure is a woman aged between 30 and 34 years with a university degree, with at least one thrombophilic mutation. Thrombophilic mutation has not been registered in only a small percentage of women with failed IVF.За неуспешната in vitro фертилизација (ИВФ) се заслужни повеќе фактори, меѓу кои последниве години се вбројува и наследната тромбофилија. Тромбофилија е состојба на предиспозиција за тромбоемболизам. Цел на трудот е да се евалуираат социодемографските карактеристики и да се испита застапеноста на мутациите за тромбофилија кај жените со неуспешна in vitro фертилизација. Материјал и методи: Во ретроспективно-проспективна студија на случај и контрола се евалуирани 52 жени, поделени во две групи. Во испитуваната група (ИГ) се вклучени 22 жени со најмалку три неуспешни ИВФ. Во контролната група (КГ) се вклучени 30 жени на иста возраст, што веќе родиле барем едно здраво дете, без акушерски компликации. Кај жените е испитано присуство на мутации на генот за фактор II протромбин (G20210A), фактор V Leiden (FVL) и метилентетрахидрофолатредуктаза (MTHFR C677T). Социодемографски податоци, податоци од лична, акушерска и семејна анамнеза беа прибрани со стандарден прашалник. Резултати: Застапеноста на националноста во испитуваните групи приближно одговара на националната структура во Република Македонија. И во двете групи најзастапена група е на возраст од 30 до 34 години (40% во КГ и 50% во ИГ). Според степенот на образование се регистрира хомогеност помеѓу двете групи. Во ИГ во најголем процент се регистрира MTHFR хетерозигот 63,6% vs. 56,7% во КГ, потоа FV Leiden хетерозигот со 13,6% vs. 3,3% во КГ, MTHFR хомозигот со 9,1% vs 6,7% во КГ и фактор II (G20210A) хетерозигот со 4,5% vs. 6,7 во КГ. 72,7% од жените во ИГ и 60% во КГ имаат присуство на една тромбофилна мутација, а 9,1% од жените во ИГ и 6,7% во КГ имаат присуство на две тромбофилни мутации. 18,2% од жените во ИГ и 33,3% во КГ немаат ниту една мутација. Заклучок: Социодемографскиот профил на жените со неуспешни ИВФ е жена на возраст помеѓу 30 и 34 години, со високо образование, кај која има присуство на најмалку една тромбофилна мутација. Само кај мал процент од жените со неуспешни ИВФ не е регистрирана ниту една тромбофилна мутација
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.
