This paper presents gamma stochastic volatility models and investigates its distributional
and time series properties. The parameter estimators obtained by the
method of moments are shown analytically to be consistent and asymptotically
normal. The simulation results indicate that the estimators behave well. The insample
analysis shows that return models with gamma autoregressive stochastic
volatility processes capture the leptokurtic nature of return distributions and
the slowly decaying autocorrelation functions of squared stock index returns
for the USA and UK. In comparison with GARCH and EGARCH models, the
gamma autoregressive model picks up the persistence in volatility for the US
and UK index returns but not the volatility persistence for the Canadian and
Japanese index returns. The out-of-sample analysis indicates that the gamma
autoregressive model has a superior volatility forecasting performance compared
to GARCH and EGARCH models.
Negative magnetic permeability media
(NMPM) can be built up by using small resonant metallic
particles like Split ring resonator (SRR) which has very
high magnetic polarisability. A group of these particles
shows a negative permeability region near and above the
resonant frequency. The continuous medium parameters
describing the SRR array can be predicted from their
individual electromagnetic behavior near the resonances.
The paper presents an optimizing software using Genetic
Algorithm (GA) to design an edge coupled two ring SRR
for a particular frequency

Gap analysis is a very useful tool for firms contemplating adoption of a new system. This
paper envisages the use of the gap analysis tool as a precursor for Indian seafood exporting firms to
adopt total quality management. Total quality management (TQM) is a management philosophy
which strives to put quality at the forefront of all its decision-making, thereby satisfying customers.
We therefore recommend that firms adopt the TQM system for better alignment of management
goals. The gap analysis tool serves as a roadmap for TQM implementation, by showing the
management where they actually are and where they want to be. The main gaps were found to be in
the areas of usage of SPC tools (66.7%), benchmarking (65.6%), top management commitment
(56.25%) and customer focus (48.1%).

The major problem of the engineering entrance examination is the exclusion of certain sections of the society in social, economic, regional and gender dimensions.
This has seldom been taken for analysis towards policy correction. To lessen this problem a minor policy shift was prepared in the year 2011 with a 50–50 proportion in academic marks and entrance marks. The impact of this change is yet to be scrutinized. The data for the study is obtained from the Nodal Centre of Kerala functioning at Cochin University of Science and Technology under the National Technical Manpower Information System and also estimated from the Centralized Allotment Process. The article focuses on two aspects of exclusion based on engineering entrance examination; gender centred as well as caste-linked. Rank order spectral density and Lorenz ratio are used to cognize the exclusion and inequality in community and gender levels in various performance
scales. The article unfolds the fact that social status in society coupled with economic affordability to quality education seems to have significant influence in the performance of students in the Kerala engineering entrance examinations. But it also shows that there is wide gender disparity with respect to performance in the high ranking levels irrespective of social groups

Abstract:
The present work deals with the Gender discrimination in the law of divorce and succession among christians.Inquiries Into the personal laws bereft of the historical develcpment of the concerned communities will be extremely inadequate as they may not help the researcher to Identify the laws' real source.In this view, the origin and development of Christian law In india has not so far been adequately gone into. Keeping In view the Importance of such a study calling for an exploration of the origin and development of the Christian community and its branching out In india as a prelude to the inqury into the Christian laws, the history of the conmunity in india was examined and the present study IndIcates that christianity In india has a diverse origin in dIfferent parts of India.And this diversity has resulted in the development of different systems of personal law for different sects among them. At present Christians in India constitute a minority but their numerical strength is not negligible. Yet they have not been able to act as an Influential group either socially or politically.The social changes and developments that swept away the community of its feet have overturned the position and the liberals in the community inspired by the changes elsewhere could bring in some statute law to govern the arena traditionally held by the customs.The history of reception of canon law concepts In different parts of India throws some light on the differences In the personal laws applicable to Christians In India.

Abstract:
Women participating in work outside home and the resultant change in Labour market structure placeing female labour as a strong component were breakthrough of twentieth centry. The major share of women labourers in India is crowding in agriculture, household industries and other traditional sectors. Shift in cropping pattern has adverse impacts on female labour. Female labour lost opportunities in the labour market this has adverse impact on family consumption. The study is directed to investigate the impact of female labour saving shift in cropping on female labour force participation and the resultant change in household consumption pattern the specific objectives this study are impact of change in the cropping pattern on employment, change female employment, family consumption pattern and changing situations of womenlabour in agriculture sector.

Abstract:
The study deals with the generation of variability for salt tolerance in rice using tissue culture techniques. Rice is the staple food of more than half of the world’s population. The management of drought, salinity and acidity in soils are all energy intensive agricultural practices. The Genetic variability is the basis of crop improvement. Somaclonal and androclonal variation can be effectively used for this purpose. In the present study, eight isozymes were studied and esterase and isocitric dehydrogenase was found to have varietal specific, developmental stage specific and stress specific banding pattern in rice. Under salt stress thickness of bands and enzyme activity showed changes. Pokkali, a moderately salt tolerant variety, had a specific band 7, which was present only in this variety and showed slight changes under stress. This band was faint in tillering and flowering stage .Based on the results obtained in the present study it is suggested that esterase could possibly be used as an isozyme marker for salt tolerance in rice. Varietal differences and stage specific variations could be detected using esterase and isocitric dehydrogenase . Moreover somaclonal and androclonal variation could be effectively detected using isozyme markers.
In this paper, we have evolved a generic software architecture for a domain specific distributed embedded system. The system under consideration belongs to the Command, Control and Communication systems domain. The systems in such domain have very long operational lifetime. The quality attributes of these systems are equally important as the functional requirements. The main guiding principle followed in this paper for evolving the software architecture has been functional independence of the modules. The quality attributes considered most important for the system are maintainability and modifiability. Architectural styles best suited for the functionally independent modules are proposed with focus on these quality attributes. The software architecture for the system is envisioned as a collection of architecture styles of the functionally independent modules identified

Considerable research effort has been devoted in
predicting the exon regions of genes. The binary indicator
(BI), Electron ion interaction pseudo potential (EIIP), Filter
method are some of the methods. All these methods make use
of the period three behavior of the exon region. Even though
the method suggested in this paper is similar to above
mentioned methods , it introduces a set of sequences for
mapping the nucleotides selected by applying genetic
algorithm and found to be more promising

Abstract:
The management of exploited species requires the identification of
demographically isolated populations that can be considered as independent
management units (MUs), failuring in which can lead to over -fishing and
depletion of less productive stocks. By characterizing the distribution of genetic
variation, population sub structuring can be detected and the degree of
connectivity among populations can be estimated. The genetic variation can be
observed using identified molecular markers of both nuclear and mitochondrial
origin. Hence, the present work was undertaken to study the genetic diversity
and population/stock structure in P. homarus homarus and T. unimaculatus
from different landing centres along the Indian coast using nuclear (RAPD) and
mitochondrial DNA marker tools which will help towards developing
management strategies for management and conservation of these declining
resources.To make consistent conservation and fisheries management decisions,
accurate species identifications are needed. It is also suggested that it is not
always desirable to rely on a single sequence for taxonomic identification.
Thus, the feasibility of using partial sequences of additional mitochondrial
genes like 16SrRNA, 12SrRNA and nuclear 18SrRNA has also been explored
in our study. Phylogenies provide a sound foundation for establishing
taxonomy. The present work also attempts to reconstruct the phylogeny of
eleven species of commercially important lobsters from the Indian EEZ using
molecular markers

The thesis deals with the results of the study of the population characteristics of the marine penaeid prawn, Penaeus monodon from South India. The present findings on the morphometric and biochemical genetic structure support the hypothesis that the populations of P.monodon of South India have homogeneous stock structure. To the contrary, the significantly different random amplified polymorphic DNA (RAPD) profiles in samples of Kochi and Chennai support the hypothesis that east and west cost populations of P.monodon are separate stocks.
