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
The Effect of Including Sea Buckthorn Berry By-Products on White Chocolate Quality and Bioactive Characteristics under a Circular Economy Context
No full textThe by-products of the extraction of sea buckthorn (Hippophae rhamnoides L.) concentrated
juice may represent a functional food ingredient for white chocolate production, as a rich source of
bioactive compounds. The effects of six treatments derived from the factorial combination of two
types of by-products (with oil or without oil) and three different concentrations (5%, 10%, and 15%),
were assessed on rheological, quality, colour, antioxidant, and mineral properties of chocolate. The
15% addition of full powder led to the highest values of max firmness, total shear energy, shear
energy, cohesiveness, gummosity, dry matter, and ABTS, compared to the untreated control, but the
two highest concentrations of the oil-deprived powder resulted in the protein content increasing.
The full powder addition always raised fat levels. Both the ‘L’ and ‘a’ colour component as well
as total carotenoids, β-carotene, lycopene, and vitamin C increased with the rise of H. rhamnoides
powder addition, compared to the untreated control. The opposite trend was shown by the ‘b’ colour
component and pH, whereas polyphenols and antioxidant activity attained higher values with the
oil-deprived powder. The content of potassium decreased upon the 15% addition of the Hippophae
rhamnoides by-product powder, compared to the untreated control, whereas calcium and magnesium
increased. The 15% H. rhamnoides full powder elicited the augmentation of phosphorus content in
chocolate, compared to the untreated control, contrary to the effect of the oil-deprived powder on
P and Zn. The employment of SBB by-products highlights the great potential for manufacturing
innovative functional foods with high nutritional value, such as chocolate
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
An approach to sustainability and circularity regarding the influence of the heat treatment duration of sugar syrup and the addition of Aronia Melanocarpa by-products as powder on the physico-chemical characteristics of artisanal chocolate
No full textThe main aim of the current research was to assess the possibilities of integrating Aronia Melanocarpa coarse powder, a by-product resulting from the processing of aronia juice, to obtain innovative chocolate with an appropriate commercial formula, in the context of the circular economy and sustainability approach, thus valorising the mentioned waste. Aronia powder is a versatile product that can be easily integrated into semi-viscous or thick food products. The experimental protocol was based on the factorial combination between 3 different concentrations of coarse Aronia powder addition (1%, 2%, 3%) plus an untreated control, and two durations of heat treatment of the sugar syrup at 103.5°C (7 and 10 minutes). The research results showed that both the concentration of chokeberry powder addition and the heat treatment duration had a significant impact on the textural parameters maximum strength and mechanical work, as well as on the colour components L*, a∗ and b*, whereas pH was only affected by Aronia powder addition. This research highlights the need to identify the most effective Aronia powder addition percentage and the technological process to obtain a qualitative or healthy chocolate
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
