Outlook for marine fisheries research in India
No full textThat marine fisheries is nothing but exploitation of a natural resource and
human interventions in harnessing the resource will only harm the health of
the ecosystem has never been better understood than at a time when the
country’s marine fisheries are passing through a period of setback, stagnation
and uncertainty. There is general belief that research in the field of capture
fisheries should result in increasing fish production from the seas. However,
the truth is that fish production from the seas depends on the productivity of
the seas, the availability of fish at given point of time, the fishing effort
expended, accessibility and vulnerability of the resources coupled with
umpteen natural factors. Marine fisheries resources, unlike the land-based
resources, are invisible, migrating and easily affected by the characteristics
of the fluid medium in which they live. The resources are subject to its own
dynamics fishing pressures and natural mortalities. Man has a lot of control
on land-based resources through interventions, but in the seas there are no
inputs from man, only exploitation. In other production systems such as crops,
man can increase production by adding fertilizers, irrigation, pest management,
using appropriate species, genetically selected seed etc. These characteristics
of the marine fishery resources make it unique and difficult to fully understand,
monitor, manage and intervene. The only opportunity for man to intervene is
through management of the capture process. It is this uniqueness of the marin
Down Memory Lane Preface
Get PDFThis is a tribute to all of you, the elders, who served
CMFRI in various capacities in the past 60 years to make
this institution a standing testimony to the devotion and
dedication of the numerous scientists, technical and administrative staff who made this institution stand apart Mohan Joseph Modayil
and shine amidst the best marine fisheries institutions in the world. Hats
off to each one of you for what you have done for CMFRI, the fruits of
which are here to stay. My personal gratitude to all of you for all the
support and encouragement you have been giving me in the past seven
years and I will always cherish the time I spent in CMFRI, contributing
my small mite to the development of this premier institution. I had requested
several of our former colleagues to write a few words about their memories
in CMFRI. Many responded promptly, a few thought it was not worth
writing. I thank you all for putting in so few words so much of feelings
and emotions which truly reflect what CMFRI means to each one of you.
And let me assure you all that each one of you mean so much for each one
of us passing through the corridors of this great institution, reminding us
that there are miles to go before we sleep, miles to go before we sleep. Thank
you all
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
