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
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
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
The Influence of Rheological Properties on The Pump Power Requirement for Transfering Ketchup
Full text linkAbstract. This research aimed to analyze the influence of rheological properties of ketchup on the pump power, required during transporting process. This research was done through using a computer programme designed for calculating and analyzing the influence of rheological properties toward materials and equipments installed in the transport system. Those rheological properties derived from laboratory analysis and literature review include viscosity and density from any type of ketchup. Results analysed by a computer programming revealed that flow behaviour Index (n) and consistency coefficient (m) were the rheological properties interacting with each other since these parameters were the viscosity of ketchup that influences energy losses in the transport system. Once the total of energy losses was obtained from the system, the pump power required for transfering the product also can be known. Based on the simulation conducted by using rheological parameters of ketchup with consistency coefficient of 12.33 PaSn, and flow behaviour Index at 0.41 was obtained total energy losses at 202.26 J/kg with the pump power requirement at 0.22 kW. Once consistency coefficient was 18.7 PaSn, and flow behaviour Index was at around 0.4, the total of energy losses increased to 277.58 J/kg with pump power requirement at 0.28 kW.
Abstrak. Penelitian ini bertujuan untuk menganalisa pengaruh dari sifa-sifat reologi dari kecap terhadap daya pompa yang dibutuhkan selama proses transfer atau pengalirannya. Penelitian ini dilakukan menggunakan suatu program komputer yang didesain untuk menghitung dan menganalisa pengaruh sifat-sifat reologi terhadap peralatan dan bahan yang digunakan pada sistem transfer. Sifat-sifat reologi tersebut diperoleh dari analisis laboratorium dan studi literatur yang berupa viskositas dan densitas dari berbagai tipe kecap. Hasil yang telah dianalisis dengan program komputer mengungkapkan bahwa index perilaku aliran (n) dan koefisien konsistensi (m) merupakan sifat reologi bahan yang saling berinteraksi, hal ini karena parameter tersebut merupakan viskositas dari kecap yang mempengaruhi kehilangan energi pada sistem transfer. Ketika total kehilangan energi dari sistem diketahui, maka daya pompa yang dibutuhkan untuk mentransferkan produk kecap tersebut juga dapat diketahui. Berdasarkan simulasi yang dilakukan dengan menggunakan parameter-parameter reologi dari kecap dengan koefisien konsistensi 12.33 PaSndan index perilaku aliran 0.41 maka diperoleh total kehilangan energi sebesar 202.26 J/kg, daya pompa yang dibutuhkan sebesar 0.22 kW. Ketika koefisien konsistensi bahan 18.7 PaSn, dan index perilaku aliran 0.4, maka total kehilangan energi meningkat menjadi 277.58 J/kg dengan daya pompa yang dibutuhkan juga meningkat menjadi 0.28 kW
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
