Not AvailableThe Society of Statistics, Computer and Applications was founded in 1998 with a goal to
provide a platform for promotion and dissemination of research in Statistics among the
statisticians, who have keen interest in the applications of Statistics to varied fields like
agriculture, biological sciences, medical sciences, finance statistics, and industrial statistics
blended with information technology. Since then the Society has been performing several
activities and promoting development of theoretical and applied research work in Statistics.
The Nineteenth Annual Conference of the Society of Statistics, Computer and Applications
(SSCA) was organized during 06-08 March 2017 at the Department of Statistics and
Computer Science, Sher-e-Kashmir University of Agricultural Sciences and Technology of
Jammu (SKUAST-J), Jammu, Jammu & Kashmir. The conference was academically very
enriching. There were some very interesting and important presentations made by scientists
of international repute and eminence. Among the many technical sessions organized, was a
session on Macro-Financial Statistics, in which delegates from Reserve Bank of India,
Securities and Exchange Board of India, National Bank for Agriculture and Rural
Development, Ministry of Statistics and Programme Implementation, Government of India
made presentations.
The Executive Council of the Society decided to bring out “Special Proceedings" of the
conference covering Keynote address, Dr. M.N. Das Memorial Lecture, Plenary talks and all
the presentations made in the session on Macro-Financial Statistics. The Executive Council
of the Society nominated Aloke Dey, V.K. Gupta, Rajender Parsad, Ashish Das, L.M. Bhar
and Dipak Roy Choudhary as the Guest editors for bringing out these special proceedings.
Distinguished speakers for Keynote Address, Dr. M.N. Das Memorial Lecture, Plenary
lectures and invited speakers in the session on Macro-Financial Statistics were invited to
submit research papers for possible inclusion in the special proceedings. After the usual
review process, 09 research papers were accepted for publication and are included in these
special proceedings.Not Availabl
Male meiosis in structural heterozygotes
ABSTRACT
The incident of structural heterozygosity is presently noticed for the first time in 9 diploid species, namely, Artemisia annua (n=9), Datura stramonium (n=12), Dicliptera bupleuroides (n=13), Hemigraphis latebrosa (n=12), Leycesteria formosa (n=9), Salvia plebeia (n=8), Senecio nudicaulis (n=5), Sonchus brachyotus (n=9) and Verbena officinalis (n=6, 7). These are heterozygous for chromosomal alternation involving 4-6 chromosomes in reciprocal translocations. All the species show >80% pollen fertility thus indicated the possibility of multivalent formation with alternate disjunction. Almost all the species are involved in some sort of meiotic abnormalities during meiosis I and II.
Key words: Multivalent, reciprocal translocations, structural heterozygosity, pollen fertility.

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
