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
Induced mutation of in vitro aquatic plant, Cryptocoryne xwillisii reitz by using gamma irradiation and IRAP analyses to distinguish the sports (clonal mutation) / Norhanizan Sahidin
Get PDFOne part of ornamental fish industry is the aquatic plants. Ornamental fish industry
is identifying as one of National Key Economic Area (NKEA) for Malaysia, under
business opportunity. Cryptocoryne xwillisii Engler ex Baum is one of the highly
demanded aquatic plants in international market. Unfortunately, the plants take months to
grow, seldom flowering and no viable seeds. The studies were done to mass-produce the
plants by tissue culture and to develop new variety by mutation.
Tissue culture of water trumpet, Cryptocoryne xwillisii Engler ex Baum, was
developed using Murashige and Skoog 1962 (MS) medium, which contained two different
plant growth regulators, namely 6-benzyladenine purine (BAP) and α-naphthalene acetic
acid (NAA). Seven different concentrations of BAP (0, 0.5, 1.0, 5.0, 10.0, 20.0 and 40.0
μM) and NAA (0, 0.5, 1.0, 5.0, 10.0, 20.0 and 40.0 μM) were investigated using a twofactor
factorial design with 10 replicates. Results of the experiments were collected and
analysed after 40 days of culture.
The results showed that the effects of plant growth regulators on increasing the
number of shoots were highly significant (p<0.01). The MS medium containing 1.0 μM
BAP alone was the optimum concentration producing 6.8 ± 1.75 shoots per explant. This
was the minimum formula concentration of BAP used that produced the highest number of
shoots. Results showed that there were twelve hormone combinations giving high mean
values of between 4 to 6 shoots per explant. All of the explants cultured in these media
produced shoot (100 %).
Although all the explants gave a positive response in terms of regeneration, they
however differed in the number and size of shoots produced. Analysis of the data using ANOVA indicated that the number of shoots produced was significantly influenced by
both BAP and NAA concentrations simultaneously. This was suggested by the significance
of the interactions between BAP and NAA which showed that BAP concentrations
affected the number of shoots differently for each concentrations of NAA tested and vice
versa.
Two new varieties of C. xwillisii have been developed through mutagenesis in this
work. Shoot tips explants of C. xwillisii were subjected to a range of 60Co gamma ray
irradiation of 0, 100, 200, 300, 400, 500, 600, 700 and 800 Gray. Results from experiments
showed that the LD50 for the tissue culture plants of C. xwillisii was at 32 Gy dose. And
was therefore, less than 32 Gray was used as the appropriate dosage for induced mutations
of the plants.
About two thousand of the shoot tips explants were irradiated using the 25 Gy and
variants from the M1, M2, M3 and M4 generations were screened for morphological
differences. The variants shoots were subcultured repeatedly until the 4th generation (M4)
to ensure stability of mutants. Although initially many regenerants with different
morphological traits were produced, only two mutants were shown to remain stable. The
mutants obtained were dwarf plants (D1) and plants of taller stature with pigmented leaves
(G1) than the controls. This was verified from the significant value of the F test in the
ANOVA where P<0.05.
The Inter-Retrotransposon Amplified Polymorphism (IRAP) markers distinguished
the D1 and G1 genomes from normal C. xwillisii genomes. The analysis revealed two
specific bands 325 bp and 420 bp using Nikita primer for the D1 mutant and 240 bp and
300 bp using combination of 3’LTR primer and LTR 6149 primer for the G1 mutant
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
