Pompano farming at Vethalai using low-cost cages: Technology demonstration initiative by Mandapam RC
An artisanal type of cage was fabricated at Mandapam Regional
Centre with 6×6 m outer and 5×5 m inner square frame,
which is made of 50mm GI pipe for farming demonstrations involving
local fishermen at Vethalai village, Ramnad District, Tamil Nadu.The ongoing pompano farming
demonstration in an artisanal type of sea cages is a way forward for
the spread of mariculture in India.

Artisanal innovation in cage farming of pompano at Vethalai, Ramanathapuram
On 25th July 2012, pompano from an artisanal cage was
harvested. The total harvest was 92 kg, the length and weight
ranges observed were 16 to 32 cm and 62 to 433 grams.The harvest was handed over to the farmer Shri.Nagadoss
by Dr. G. Gopakumar, Scientist-in-Charge. The farm gate price
for the harvested pompano was `120/kg- and it was sold by
the merchant in the retail market at `180/kg-.

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

Not AvailableThe impact of motorization of traditional craft on two fisheries resources, viz. tunas and whitebait
anchovies, was studied. A conspicuous increase in the annual tuna catch was seen from 1984 due to the
increased effort expended by the motorized craft by using more units of drift nets, hooks and lines than
non-motorized craft. The tuna landing increased from 361 tonnes during the pre-motorization period to
1976 tonnes during the motorization period. On the contrary, the anchovy landing came down from 580
tonnes during the pre-motorization period to 386 tonnes on motorization. A decline was noticed in the effort
expended for whitebait anchovies but the catch rate did not show a steep decline which indicated that the
reduction of effort was not due to the decrease in the catch rate. The shifting over of motorized units to drift
net and hooks and lines operation seems to be the major reason for the decline in the effort of boat siene
and nelholi vala which are the main gears for whitebait anchovies.

The motorization of traditional craft was
initiated in central Kerala by 1980. It spread
to northern and southern areas by 1983 (Balan
et al. 1989). At Vizhinjam, the most important
fish landing centre in Trivandrum, the
motorization was initiated during the middle
of 1982. A substantial increase in the effort
from the motorized craft was recorded from
A 984 which resulted in an immediate increase
in the total fish catch at Vizhinjam. An account
of the traditional fishery in the area has
been given by Luther et al. (1982) and Nair et
al. (1988) and the initiation of motorization of
traditional craft in the area has been reported

Motorization has extended the fishing areas of
traditional craft to relatively more distant
grounds and has increased the yield of certain
resources like tunas which are caught chiefly
by drift net and hooks and lines. This has

Fast Regression of the Tritium Breeding Ratio in Fusion Reactors
The tritium breeding ratio (TBR) is an essential quantity for the design of
modern and next-generation D-T fueled nuclear fusion reactors. Representing the
ratio between tritium fuel generated in breeding blankets and fuel consumed
during reactor runtime, the TBR depends on reactor geometry and material
properties in a complex manner. In this work, we explored the training of
surrogate models to produce a cheap but high-quality approximation for a Monte
Carlo TBR model in use at the UK Atomic Energy Authority. We investigated
possibilities for dimensional reduction of its feature space, reviewed 9
families of surrogate models for potential applicability, and performed
hyperparameter optimisation. Here we present the performance and scaling
properties of these models, the fastest of which, an artificial neural network,
demonstrated and a mean prediction time of ,
representing a relative speedup of with respect to the expensive
MC model. We further present a novel adaptive sampling algorithm,
Quality-Adaptive Surrogate Sampling, capable of interfacing with any of the
individually studied surrogates. Our preliminary testing on a toy TBR theory
has demonstrated the efficacy of this algorithm for accelerating the surrogate
modelling process.Comment: 13 pages, 8 figure

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
Answering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
