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
The Influence of Intellectual Capital on Financial Performance of Indonesian Conventional Banks
No full textThis study is to determine how much influence Intellectual Capital has on financial performance of Indonesian Conventional Banks. The type of research conducted is quantitavie research, which is research related to numbers that can be measured. Sample selection using purposive sampling as many as 39 Indonesian Conventional Bank listed on the Indonesian Stock Exchange (IDX) consistently publish complete financial reports during the 2017-2023 period.
The research data used in the form of panel data of the period 2017-2023 which is processed using eviews 10 software. The Random Effect Model wasused to analyze the effect of independent variables, namely Value added Capital Employed (VACA), Value Added Human capital (VAHU), Structural Capital Value Added (STVA), on dependent variables, namely Return on Equity (ROE) and Return On Assets (ROA).
The results of this study indicate that Value added Capital Employed (VACA) has a positive and insignificant effect on Return on Equity (ROE) of Indonesian Conventional Banks. While Value added Capital Employed (VACA) has a positive and significant effect on Return On Assets (ROA) of Indonesian Conventional Banks. Value Added Human capital (VAHU) has a positive and significant effect on Return on Equity (ROE) of Indonesian Conventional Banks. While Value Added Human capital (VAHU) has a positive and significant effect on Return On Assets (ROA) of Indonesian Conventional Banks. Structural Capital Value Added (STVA), has a negative and significant effect on Return on Equity (ROE) of Indonesian Conventional Banks. While Structural Capital Value Added (STVA), has a negative and insignificant effect on Return On Assets (ROA) of Indonesian Conventional Banks.96 PagesSkripsi Sarjan
STUDI OPTIMASI PEMBUATAN KOMBUCHA DARI EKSTRAK TEH HITAM SERTA UJI AKTIVITAS ANTIOKSIDAN
No full textKombucha merupakan minuman hasil fermentasi yang telah diinokulasikan dengan sejenis kultur simbiotik campuran antara bakteri dan khamir pada larutan teh manis. Teh kombucha, memiliki rasa asam yang bermanfaat sebagai minuman penyegar juga menyehatkan bagi kesehatan, hal ini disebabkan oleh adanya aktivitas antioksidan yang terkandung didalamnya. Proses pembuatan kombucha dapat dipengaruhi oleh jenis dan kadar teh, kadar gula, kadar starter, dan waktu fermentasi yang mengakibatkan adanya perbedaan baik antara aroma, rasa serta kandungan kimianya. Oleh sebab itu, maka diperlukan suatu kondisi optimum untuk memperoleh kombucha dengan hasil yang lebih baik. Dalam penelitian ini, dilakukan studi optimasi pembuatan kombucha dari ekstrak teh hitam terhadap waktu fermentasi, kadar teh dan kadar starter serta aktivitas antioksidan. Bertujuan untuk mengetahui kondisi optimum terbentuknya teh kombucha serta aktivitas antioksidan hasil dari kondisi optimumnya. Metode yang digunakan dalam penentuan kondisi optimum didasarkan pada pengukuran ketebalan nata, serta pengujian aktivitas antioksidan dengan menggunakan metode DPPH. Berdasarkan hasil penelitian, diperoleh bahwa kondisi optimum terbentuknya kombucha berdasarkan waktu fermentasi teroptimasi diperoleh selama 14 hari, kadar teh sebesar 1,2 % b/v dan kadar starter sebesar 3 % b/v + 10 % v/v. Aktivitas antioksidan pada kombucha yang dihasilkan pada kondisi optimum diperoleh sebesar 90, 19 % jauh lebih besar daripada teh biasanya 48,04 %.

Kombucha is a fermented beverage that has been inoculated with a sort of mix between a symbiotic culture of bacteria and yeast in a solution of sweet tea. Kombucha tea, having a sour taste which is also useful as healthy beverages for your health, it is caused by the activity of antioxidants contained there in. The process of making kombucha may be influenced by the type and grade of tea, sugar, level starter, and fermentation time resulted in the difference between aroma, taste and chemical content. Therefore, we need optimum conditions to obtain kombucha with better results. In this study, conducted optimization studies kombucha manufacture of black tea extract on the fermentation time, the levels of tea and a starter as well as the levels of antioxidant activity. Aims to determine the optimum conditions for the formation of kombucha tea and antioxidant activity results from its optimum condition. The method used in the determination of optimum conditions based on the measurement of the thickness of nata, as well as testing the antioxidant activity using DPPH method. Based on the results of the study, found that the optimum condition based on the time of formation of kombucha fermentation derived optimized for 14 days, the levels of tea at 1.2% w / v and starter levels of 3% w / v + 10% v / v. The antioxidant activity of the kombucha resulting in optimum condition was obtained by 90, 19% is much larger than the usual tea 48.04%.
