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
Systems of change: a study on the nature of ICT and AI and their impact on industrial trajectories
Get PDFThe dissertation emphasises the role of technological side of ICTs in establishing industrial links both within and beyond ICT cluster or system. The overarching aim of the dissertation is to bring technological and systemic aspects into economic mechanisms driving the process of digitalisation in different industries. The dissertation consists of four chapters and has a funnel-like structure; it starts with the study on macro productivity dynamics indicated with intersectoral labor mobility moving away from industries with depleted techno-economic opportunities. The dissertation continues with the research on two technology systems - ICT and AI - as sources of new technological opportunities and economic activities setting in motion the dynamics described before. It is important to estimate the magnitude and structure of the ICT's "grip" over the countries' economies and rationalise AI's nature to construct better predictions with regard to their impact on established technological trajectories, productivity, employment and long-term growth. Thus, the concluding study is an example of envisaging potential futures for the semiconductor industry whose technological trajectory is disrupted by the emergence of AI. The employed methods include analytical modeling, text analysis, decomposition exercise, productivity analysis, network analysis, and metrics of economic complexity such as relatedness. The author worked with various sources of secondary data such as PATSTAT, REGPAT, COR&DIP, STAN OECD, as well as with primary data collected through webscraping and text mining
Additional file 5: Figure S3. of A robust (re-)annotation approach to generate unbiased mapping references for RNA-seq-based analyses of differential expression across closely related species
Get PDFCorrelation plots for RPKM-limma. Relation between length differences and the log2-fold change. Comparisons between D. mauritiana and D. melanogaster are shown on the left side, comparisons between D. mauritiana and D. simulans are shown on the right side. On the first row, the published annotations are used as mapping references; on the second row, the directly re-annotated references are used as mapping references and on the third row, the reciprocally re-annotated references are used. Dots represent genes with length difference > 49 bp in these annotations. Genes significantly differentially expressed in the presented analysis (padj < 0.05) are shown in red. A negative log2-fold change indicates higher expression in D. mauritiana. A positive length difference indicates that the ortholog of D. mauritiana is longer. The p-value and rho of the Spearman’s rank correlation are indicated on the upper right side of the plots. (PDF 3811 kb
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
