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
Genetic variation affecting fitness in the Eastern oyster (Crassostrea Virginica)
No full textGenetic variation or genetic diversity plays a crucial role in the adaptability and survival of oyster populations. Comprehending its influence on oyster fitness helps us understand oyster adaptability and contributes to genetic improvement of oysters for aquaculture. This dissertation, comprised of five chapters, delves into the significance and practical applications of genetic variation in the context of oyster fitness and adaptability.Based on the foundation of genetic variation's crucial role in oyster adaptability and survival, this dissertation explores the phenomenon of heterosis and its implications for genetic diversity within oyster populations. Chapter 1 delves into the performance of inbred and hybrid oysters from the D larvae to adult stage, providing concrete evidence of heterosis in terms of oyster survival and growth. The utilization of the recently developed high density single nucleotide polymorphism (SNP) array provides insight into the importance of heterosis and genetic diversity in enhancing oyster performance including survival and growth, contributing to our understanding of heterosis in oysters. Chapter 2 addresses genetic load in the eastern oyster by analyzing genetic markers showing segregation distortion (SD) during the larval stage. This analysis reveals why oysters are sensitive to inbreeding and suffer from inbreeding depression. The high proportion of markers with SD suggests that balancing selection is the main contributing factor to the genetic load and genetic diversity. Furthermore, the discovery of high levels of null alleles in the eastern oyster genome offers insights into other forms of genetic variation in oysters. In Chapter 3, the focus shifts to understanding genetic mechanisms of growth and heterosis through transcriptome analysis. Through gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, distinctions in growth-related physiological strategies among different size groups are illuminated. The identification of candidate genes associated with shell formation and stress response suggest a relationship with growth. Comparing hybrid and inbred transcriptome data suggests hybrids have a more sophisticated regulatory network for optimized stress response. This chapter argues that the observed heterosis in oyster growth results from a combination of additive and non-additive genetic effects. Chapter 4 identifies candidate loci and genes associated with field survival by studying the genetic changes after field mortalities. The findings suggest that field survival is a polygenic trait influenced by many genes related to disease resistance, growth, and thermal tolerance. This study provides a rich source of genetic data for possible genetic improvement of oysters. Finally, Chapter 5 conducts genomic selection (GS) to improve dermo resistance by using genome-wide genotype data. The performance of the F1 generation proves the effectiveness of GS in improving dermo resistance. And it is the first report on the successful application of high-density SNP array and GS in improving dermo resistance in the eastern oyster.
In conclusion, this dissertation provides a comprehensive examination of the critical role of genetic variation in the adaptability and survival of eastern oysters. Through detailed investigations spanning from inbred and hybrid performance analyses to high genetic load assessments, to the exploration of genetic mechanisms underlying growth and heterosis, this research highlights the significance of maintaining and promoting genetic diversity within oyster populations. The utilization of high-density SNP arrays and transcriptome data has not only shed light on the phenomenon of heterosis but also contributed to genetic improvement practices in oyster aquaculture. By identifying candidate loci and genes associated with key traits such as field survival and growth, this study provides valuable insights into genetic architecture of production traits, potentially useful for the genetic improvement of oysters. This research demonstrates that GS is effective for improving polygenic traits such as dermo resistance. These findings emphasize that genetic variation is crucial for the adaptability of oysters, and understanding this diversity is critical for oyster aquaculture, breeding and conservation.Ph.D.Includes bibliographical reference
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

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.
