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
N-body simulations of Globular Cluster-like systems
No full textThe dynamics of self-gravitating globular cluster-like systems, containing N = 10(5) stars, has been simulated for 6 - 10 crossing times. We followed the evolution of three different spherical systems. The first two are quasi-virialized clusters, (with and without the presence, in the centre of mass, of a black hole); the third case regards the initial violent collapse of a spherical system.The dynamics of self-gravitating globular cluster-like systems, containing N = 10(5) stars, has been simulated for 6 - 10 crossing times.

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
Shelf life study of dried pumpkin in biopolymeric films by accelerated shelf life test
No full textIn the context of consumers’ increasing demand for high-quality food, the development of strategies to prolong the shelf-life of these products can attract the interest of the food industry and the processed food field. Moreover, consumers’ awareness on environmental sustainability is increasing and leads to choose alternative packaging for food products. Bio-based polymeric films are eco-friendly and good alternatives of traditional plastic packaging [1].
Pumpkin is widely cultivated in Italy throughout many regions and in many temperate climate areas of the world. It has high nutritional value because it is rich in antioxidants, vitamins, minerals, fibres and is recommended in diets because of its low calories content [2]. After harvesting, pumpkins are stable for 1-3 months; after peeling they are more perishable and rapidly lose organoleptic quality for microbial spoilage, softening, moisture loss and colour changes. For this reason, pumpkin is generally processed to obtain juice, pomace, pickles, dried products in many countries worldwide [3]. Drying is a suitable technique for preserving nutritional value and prolonging the shelf life of pumpkin. Moreover drying combined with a pretreatment is a efficient method for reducing changes in colour and antioxidant activity and for improving preservation [4].
In this study the shelf life of dried pumpkin slabs, Cocurbita moschata, packed in a polyethylene bag and in a biopolymeric bag in PLA, polylactic acid polymer from corn starch, was investigated. The objective was to evaluate the efficiency of the bio-packaging for the preservation of dried pumpkin compared to the plastic packaging (PE). The shelf life of dried foods, when properly stored, lasts from 4 to 12 months. Accelerated Shelf-life Test (ASLT) was performed in order to determine the shelf life in a relatively shorter time. By this method, the product is stored under high stress conditions, such as high temperature, to accelerate the deterioration process.
During the trial, the total microbial aerobic count, weight loss, pH and colour of the packed dried pumpkin have been monitored at 30°C every 3 days for 12 days, at 40 °C every 3 days for 9 days at 50 °C and 25°C every 2 days for 6 days. In particular the colour was expressed in terms of polar coordinate Chroma that indicates the dullness/vividness of the product.
The results obtained showed that the shelf life of dried pumpkin, packed in PLA and PE bags, can be predicted using the ASLT by selecting an index of quality
