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
Study Of Protein, Lipid And Metabolite Profiles In Type 2 Diabetes Mellitus (T2dm) Rats Model Upon High Calories Food Intake And Metformin Treatment
Get PDFType 2 diabetes mellitus (T2DM) is a metabolic disease characterized by high blood glucose due to insulin resistance or insulin deficiency. Type 2 diabetes is primarily caused by an unhealthy lifestyle. Lifestyle management such as healthy diet and physical activity is essential for diabetes management. Food prepared in oil or high fat content add taste and textures to the palate; therefore, it is more favourable by most people. In this study, metabolic parameters, proteins (kidney), lipids (blood), and metabolites (urine) profile of T2DM rats were studied upon palm oil enriched-high fat diet and metformin treatment
Sodium Cloride And Sucrose Rescued Cupriavidus Necator H16 Δsecb Mutant When Grown In Nutrient Rich Media
Get PDFSecB adalah salah satu komponen utama dalam sistem translokasi protein Sec
terutamanya bagi bakteria Gram-negatif. Dalam kajian ini, fungsi SecB telah dikaji
dengan membina mutan Cupriavidus necator H16 ΔsecB. Mutan ini telah dibina
melalui pertukaran alel menggunakan vektor swa-hapus pDM4. Untuk mengesahkan
perubahan fenotip disebabkan oleh gen yang dimutasi, mutan pelengkap juga dibina,
yang mana vektor pBBR1MCS2 yang mengandungi gen SecB telah dikonjugasi ke
dalam mutan C. necator H16 ΔsecB. Jenis liar, C. necator H16 ΔsecB mutan dan
mutan pelengkap telah dikaji mengguna sistem Biolog Phenotype Microarray. Mutan
pelengkap menunjukkan fenotip jenis liar, bermakna penglengkapan secB telah
berjaya. Mutan Cupriavidus necator H16 ΔsecB tidak menunjukkan perbezaan yang
signifikan apabila ditumbuh dialam kebanyakan substrat.
SecB is one of the key players in the Sec protein-translocation system
ubiquitous to Gram-negative bacteria. In this study the function of SecB was studied
by studying an unmarked Cupriavidus necator H16 ΔsecB mutant. The mutant was
constructed through allelic exchange utilizing the pDM4 suicidal vector. In order to
confirm that the phenotypic change is due to the mutated gene, a complementation
mutant was also constructed, in which vector pBBR1MCS2 harbouring a secB gene
was introduced into the C. necator H16 ΔsecB mutant via conjugation. The wild type,
C. necator H16 ΔsecB mutant and the complementation mutant were characterised
using Biolog Phenotype Microarray. The result shows that the complementation
mutant exhibits the wild type phenotype, indicating successful complementation of
the unmarked secB deletion. The C. necator H16 ΔsecB mutant did not show any
significant difference when grown on most substrate
