Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
BIOMARKERS IDENTIFICATION AND THERAPY TARGET IN MACROPHAGE OF ATHEROSCLEROSIS: SYSTEMATIC REVIEW
Full text linkMacrophages are known to play an important role in the initiation and progression of atherosclerosis; however, the molecular signaling pathways in macrophages that are responsible for plaque rupture have not been fully identified. This study aims to identify biomarkers and therapy targets in macrophages in atherosclerotic conditions by systematic review. Research procedure of systematic reviews using the PRISMA protocol. The search engine used in this study is PubMed, with the keywords ([macrophage] AND atherosclerosis) AND (signaling pathway OR signaling pathway), the reference application used is Zotero to screen clinical articles. There were 689 articles identified and 11 clinical articles in inclusion criteria were obtained. The identification resulted in 30 biomarkers associated with macrophages in atherosclerotic conditions. The proposed biomarkers of atherosclerosis are interleukin (IL)-1β and IL-18. The proposed potential therapy targets for atherosclerosis are LOX-1 and schematic images of biomarkers in atherosclerotic plaques
Variations on the Author
Full text link“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
Kajian Pustaka 27 Tanaman Indonesia dengan Aktivitas Antihipertensi
Full text linkKasus hipertensi di Indonesia selalu meningkat setiap tahunnya. Berdasarkan data Riset Kesehatan Dasar (Riskesdas) tahun 2018, sebanyak 34,11% penduduk Indonesia berusia >18 tahun mengalami hipertensi. Obat anti hipertensi digunakan dalam jangka waktu lama, bahkan seumur hidup, dan efek sampingnya tidak sedikit. Kajian pustaka mengenai efek antihipertensi dari 27 tanaman Indonesia telah dilakukan dengan mengumpulkan data ScienceDirect (sciencedirect.com), PubMed (pubmed.ncbi.nlm.nih.gov), dan Google Scholar (scholar.google.com), serta buku Cabe Puyang: Warisan Nenek Moyang Edisi I. Pustaka menunjukkan banyak tumbuhan yang digunakan secara empiris oleh masyarakat. Sebagian tumbuhan tersebut telah melalui uji praklinis dan uji klinis. Tanaman yang berkhasiat antihipertensi secara empiris berjumlah 27 dan yang tidak ditemukan baik data uji praklinis maupun data uji klinisnya adalah tanaman buni (Antidesma bunius Spreng), trengguli (Cassia fistula Linn), lobi-lobi (Flacourtia inermis Roxb.), ranti (Solanum nigrum Linn), pulai (Alstonia spectabilis R. Br), dan srigading (Nyctanthes arbor-tristis L.). Keenam tanaman tersebut berpeluang untuk diteliti khasiat antihipertensi dan keamanannya.

Berdasarkan data Riset Kesehatan Dasar (Riskesdas) tahun 2018, sebanyak 34,11% penduduk Indonesia berusia >18 tahun mengalami hipertensi. Obat anti hipertensi digunakan dalam jangka waktu lama bahkan seumur hidup dan efek sampingnya tidak sedikit, oleh karena itu dilakukan studi pustaka tanaman Indonesia yang berkhasiat antihipertensi.

Hasilnya banyak tumbuhan yang sudah digunakan secara empiris oleh masyarakat. Sebagian sudah melalui uji praklinis, bahkan ada yang sudah diuji klinis. Tanaman yang berkhasiat antihipertensi secara empiris berjumlah 27 dan yang tidak ditemukan baik data uji praklinis maupun data uji klinisnya adalah tanaman buni (Antidesma bunius Spreng), trengguli (Cassia fistula Linn), lubi-lubi (Flacourtia inermis Roxb.), ranti (Solanum nigrum Linn), pulai (Alstonia spectabilis R.

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
