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
Investigating the Performance of Geocell Reinforced Unbound Layer Using Light Weight Deflectometer
No full textRapid road infrastructure construction has become a trend in India and around the world. Many road projects have necessitated early-stage maintenance during the last few decades. To figure out what's causing it, a structural evaluation study is needed to analyze the existing material qualities of the pavement. Many studies have evaluated flexible pavements using widely used NDT technologies such as LWD, BBD, and FWD. While LWD is gaining acceptance and popularity as an in-situ spot-testing device all over the world, only a few studies have been done and are necessary to be carried out in India in order to make the use of the LWD technique beneficial in road repair projects. The primary objective of this research is to use LWD to estimate the subbase surface and subgrade modulus of the unreinforced and reinforced sections and to provide rehabilitation options based on the LWD results. The lightweight deflectometer (LWD) is a highly advanced and sophisticated device that was developed to evaluate the deformation modulus (Esub LWD) of compacted geomaterials as an alternative density test.
One of the ground improvement techniques rapidly expanding is geosynthetic soil reinforcement, primarily due to cost-effectiveness, simplicity, and ease of construction. The most recent development in the field of geosynthetics soil reinforcement is the use of geocells at the base and subbase courses of the pavement systems. Geocells improve pavement performance while also attaining sustainable goals, as shown by research, testing, field trails, and case studies. This research aimed to figure out what causes improved bearing capacity and what benefits geocells deliver. Geocell was used in this study in a variety of layouts and sizes with gradation (Grade I as per MoRTH for both Laboratory and Field Evaluations. It was also discovered that the best performance is achieved when a geocell of height 125 mm layer is installed in the unbound layer.
The performance improvement was presented in terms of Modulus Improvement Factor (MIF). This study intends to use the LWD device and present the ranges of deformation modulus for various geomaterials from several studies. For instance, in the case of soils and aggregates, deformation modulus values were found to be in the range of 35-60 MPa and 80-120 MPa, respectively. In addition, several studies have been compiled to completely comprehend the relationship between LWD and various geocell layouts. In addition to the cost savings, this would
v
conserve natural materials like aggregates used in pavement construction. Overall, the inclusion of geocell in the subbase layer helps improve the life, uniform distribution of load and provides an economical and sustainable solution to the present practices.
Finite Element Analyses (FEA) were used in the investigation, and the results were confirmed through laboratory tests. The objective is to understand the behavior of unpaved roads with unreinforced and geocell-reinforced subbase. Based on FEA and laboratory evaluation, the study investigated that the geocells are beneficial when construction is performed with a lower/marginal subbase and subgrade material. The geocells allow placement on top of the weak quality subgrade
Child Alert System
Get PDFIn the early times questions come out on how to protect the child or make them safe as many children were facing death, being lost or come across some serious accidents. Later many researches come out and many systems were developed for different child safety purposes like health safety, danger from surroundings etc. As technology advanced many systems were developed including tracking, wrist bands and alarm system. In this paper we will describe some of the child alert systems that can prove handy and functional
