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
Pembaziran bahan binaan / Muhammad Faiz Che Ismail
No full textLaporan ini terbahagi kepada beberapa bahagian dan dimulakan dengan latar belakang syarikat dan latar belakang projek pembinaan. TSP Numumwah Sdn. Bhd. merupakan syarikat yang terlibat secara langsung bagi projek ini. Penglibatan TSP Numumwah Sdn. Bhd. di dalam pembinaan semenjak tahun 1985 lagi sebagai kontraktor pembinaan kelas 'D' dengan nama TSP Cahaya. Syarikat ini telah menubuhkan syarikat Sdn. Bhd. Untuk mendaftar kontraktor kelas 'A'. Kos projek ini bernilai RM 6,711,840.00. Tarikh milik tapak ialah pada 10 Ogos 2009 dan dijangka siap pada 28 November 2010. Hasil pemerhatian penulis mendapati bahan-bahan seperti konkrit, batu-bata, batu-baur, kayukayan, besi tetulang dan mortar. Pembaziran bahan-bahan binaan ini kebanyakan disebabkan sikap pekerja yang tidak bertanggungjawab dalam penggunaan bahan binaan. Selain itu, antara kesan-kesan lain ialah seperti sistem pengurusan kurang teratur, aktiviti jenayah, tempat penyimpanan bahan yang kurang sesuai dan lebihan stok. Namun demikian, untuk mengatasi masalah ini pelbagai langkah diambil oleh pihak kontraktor seperti memantau aktiviti kerja dan menghadkan kemasukan pekerja tidak mahir
Metabolite profiling, lignin accumulation and gene expression of oil palm germinated seed treated with Hendersonia GanoEF1
Get PDFOil palm (Elaeis guineensis Jacq.) is considered as a golden crop and also one of the main contributors to economy of Malaysia. Unfortunately, basal stem rot (BSR) disease remains as a major obstacle in oil palm cultivation and production in Malaysia. The uses of biocontrol agents become the main attention to control and suppress the plant disease. The objective of this study is to compare the metabolite profiling, lignin accumulation and gene expression of root of oil palm germinated seed treated with Hendersonia toruloidea (GanoEF1) and Ganoderma boninense. Endophytic fungi Hendersonia GanoEF1 was obtained from GanoDROP Unit (MPOB) Kajang, Selangor. Four hundred and fifty oil palm germinated seed were used and arranged randomly by using completely randomized design (CRD). The experiment conducted using four-week-old oil palm germinated seed with five following treatments; germinated seed control untreated and uninfected with G. boninense (TC), germinated seed treated Hendersonia GanoEF1 (TH), germinated seed infected G. boninense (TG), germinated seed treated Hendersonia GanoEF1 and infected with G. boninense (THG), and germinated seed control with uninfected rubber wood block, RWB (TB). Methanol extraction methods were used for metabolite profile analysis. Sixty five compounds from different treatments were selected as main compounds. Three types of sterols detected from these treatments such as β-sitosterol, Stigmasterol and Campesterol were used as a potential indicator to detect the present of pathogen (stress) in plant. Using the Venn-digram, few compounds have been identified and used to detect the present of G. boninense and Hendersonia GanoEF1 in oil palm roots were: Methyl 6-0-[1-methylpropyl]-β-D-galactopyranoside; Hexadecanoic acid, methyl ester; Tetradecanoic acid and 9,12-Octadecadienoic acid (Z,Z)-, 2-hydroxy-1-(hydroxymethyl)ethyl ester. Determination of lignin accumulation and total lignin content in oil palm root is one of the potential methods to indicate the level of plant‘s stress. Two cm above the root tips were cut to determine the lignin accumulation whereas for total lignin content, 100 mg of root were used to compare the acid-soluble and acid- insoluble lignin between the treatments. Highest thickness of lignin was found in treatment TG (82.65 ± 2.98) and the lowest in treatment TC (61.11 ± 1.05). For total lignin content, treatment TC shows the highest (263.73 ± 22.52) and the lowest found in treatment TG (188.43 ± 7.42). Study the gene expression of plant defence-related enzymes which are superoxide dismutase (SOD) and catalase (CAT) is also one of the method that possibily used to indicate the stress level in plant. Highest SOD level was found in treatment TC (24.56 ± 0.12) and lowest in treatment THG (23.49 ± 0.19) whereas highest CAT found in treatment THG (17.62 ± 0.06) and lowest in treatment TC (16.98 ± 0.19). This study revealed that Hendersonia GanoEF1 is suitable as an effective biological control agent for promoting the growth of oil palm seedlings and controlling BSR disease
