Winter School on Impact of Climate Change on Indian Marine Fisheries Lecture Notes - Part 1, CMFRI, Cochin held on 18.1.2008 - 7.2.2008
Get PDFThe man-made problem of climate change is emerging as the biggest test for humankind. The
greenhouse gas emission is increasing rapidly, and if unchecked, is likely to reach unprecedented and
irreversible levels in another three to four decades. Every individual will have to experience the hardship of
climate change in the near future. This challenge calls for preparedness and action at every level

Concept and objectives of stock assessment
Get PDFAmong all the exploited natural animal resources, fisheries resources are the largest. The
magnitude, dynamics and resilience of fish stock pose great challenge to their assessment as
well as management. The fishery resources are unique at least on three factors (Vivekanandan,
2005). (i) Many species have wide spatial distribution. (ii) Several species show wide temporal
variations in abundance. (iii) Since the resources cannot be seen visually, gaining an insight
into the structure and function of the resources is a challenge. It is reported that 667 marine
species are fished (Sathianandan et al., 2013) by 194,490 boats (DAHDF and CMFRI, 2012)
along the Indian coast, showing the dynamism of fisheries. To exploit these resources, to
manage and develop the fisheries, and to conserve the fish stocks, it is essential to have
accurate information on these stocks such as how much or how many are present in the
sea, what is their reproductive capacity, their growth potential, etc
Adaptive Sampling and Routing in a Floodplain Monitoring Sensor Network
No full textWe describe the design of a flood warning system which uses a set of sensor nodes to collect readings of water level and a grid-based flood predictor model developed by environmental experts to make flood predictions based on the readings. The reporting frequency of sensor nodes is required to be adaptive to local conditions as well as the flood predictor model to optimize battery consumption. We therefore propose an energy aware routing protocol which allows sensor nodes to consume energy according to this need. This system is notable both for the adaptive sampling regime and the methodology adopted in the design of the adaptive behavior, which involved development of simulation tools and close collaboration with environmental experts
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
