Government Policies and Programmes for Tribal Development in West Bengal, 1947-2011
Full text linkThe present dissertation deals with the problems concerning the fate of the Scheduled Tribes in West Bengal between the years 1947 and 2011. It analyses this steps that have been taken by both the Centre and State Governments in this regard. A brief review of the existing literature on the subject serves as a Foreword to the discussion. The different viewpoints that have been advanced from time to time with regard to the policy to be under taken towards the tribal population of India have also been discussed a length. We have examined the measures undertaken by the State and Central Government with regard to the Scheduled Tribes of India under the following heads;- economy, education, health and social security. A concluding chapter rounds off the discussion

No full textA study on doubt fuzzy BCK/BCI-algebras and other algebraic structures
Full text linkFuzzy set theories provide strict mathematical frameworks using vague phenomena
and can be precisely and rigorously studied. The core theories in mathematics such as
algebra, topology, lattices and analysis are subject to fuzzi cation. Many researchers
have dealt with subalgebras, ideals, subimplicative ideals, P-ideals, H-ideals, implica-
tive ideals, hyper structure etc. and their fuzzi cation.
This study attempts to introduce a new class of algebraic structures in intuitionis-
tic fuzzy set and interval-valued fuzzy set. The concepts of doubt intuitionistic fuzzy
subalgebra/ideals, doubt intuitionistic fuzzy H-ideals, doubt intuitionistic fuzzy sub-
implicative ideals, doubt intuitionistic fuzzy P-ideals and doubt intuitionistic fuzzy
translations of doubt intuitionistic fuzzy sub-implicative ideals are introduced for
BCK/BCI-algebra and their properties are duly characterized.
The notion of direct product of two doubt intuitionistic fuzzy subalgebras and two
doubt intuitionistic fuzzy H-ideals of two BCK/BCI-algebras has also been discussed
and some related properties have investigated. We have also found that the direct
product of two intuitionistic fuzzy sets becomes doubt intuitionistic fuzzy H-ideals
and doubt intuitionistic fuzzy subalgebras if and only if for any t; s 2 [0; 1], upper and
lower level sets are H-ideals or subalgebras of BCK/BCI algebra X Y .
Results of doubt interval-valued fuzzy subalgebras and doubt interval-valued fuzzy
ideals in BCK-algebras and BF-algebras are also provided. Cartesian product of two
interval-valued fuzzy sets is de ned and its properties are established. The relation
between doubt intuitionistic fuzzy ideals and an upper level and lower level cuts of
BCK/BCI-algebra have also been explored.
Besides doubt intuitionistic fuzzy hyper lters in hyper BE-algebras have also been
established in the present work
Evolution of Public Libraries in Colonial Bengal: 1800-1947
Full text linkColonial rulers were almost indifferent to spread mass education in the country. Public libraries were established in town and villages in Bengal by the active initiative of common people to spread mass education. Evolution of 275 public libraries in Colonial Bengal during 1800-1947 have been taken in the study. It has framed to trace the genesis of public libraries in Colonial Bengal, to trace the gradual development of public libraries in Bengal, to trace the role of secret societies to develop public libraries, to trace the role of colonial public libraries in preservation as well as dissemination of knowledge, to trace the role of public libraries in social welfare activities, to trace the role of Bengal Library Association to create library awareness among people. A comprehensive list of primary as well as secondary sources used to trace the development of public libraries and community information need of the period. The study in its six chapters observed that most of the libraries during the period were the product of voluntary effort. Since approach of twentieth century public libraries were appearing as strong media to preach nationalism attaching themselves as a branch of secret societies. Rare books, journals, patriotic history and local history are found in their collection. In order to attract mass- base to the library, social services used to perform from the library. Present public library system of both west Bengal and Bangladesh are found as successor of Colonial Public library system in Bengal in many aspects
The Unity of Phenomenal Consciousness and The Unity Thesis: A Critical Study
Full text linkConsciousness occupies a fundamental place in our daily life. Conscious experience always
comes as a unified phenomenon. We find many different senses of ‘unity’. The main purpose
of the thesis is to present a critical discussion of the unity of phenomenal consciousness and
also the critical evaluation of the unity thesis proposed by Tim Bayne in his magisterial work
entitled ‘The Unity of Consciousness’ published in 2010.The thesis is divided into seven chapters including introduction and concluding
remarks. I begin my discussion with definition and nature of different types of consciousness
in chapter 1. In the 2nd chapter I have focused only on the nature of phenomenal
consciousness and also the possibility of the unity of phenomenal consciousness critically. In
the third chapter of the thesis I have critically explored the nature of phenomenal unity and
the unity thesis of consciousness following Tim Bayne. In the fourth chapter, I have
considered some arguments in defense of the unity thesis. Some philosophers oppose the
unity thesis and they argue on the basis of some facts of behaviourally and clinically
disordered patients and claim that there are some kinds of breakdown of unity in
consciousness of these persons. These opposite views have been discussed in chapter five. In
chapter six, I discuss some recent criticisms against the mereological account and I have tried to respond from my own standpoint. In the concluding observations, I argue that there are
some positive aspects to explain the nature of the unity of phenomenal consciousness without
involving any kind of category mistakes. Again with the help of this thesis, I shall be able to
explain the problem of consciousness effectively and get the plausibility of achieving a
unique way to explain the historical problem without any ambiguity. Lastly, I think that the
unity thesis of Tim Bayne is more revolutionary than the others to deal with the problem of
consciousness like Kantian Copernican Revolution. After dwelling upon the arguments for
and against of the unity thesis I came to the conclusion that the cases of disunity as shown by the opponents are nothing but the contextual manifestation of the unity. The whole matter can
be represented in an argumentative form. The concept of disunity necessarily comes after the
concept of unity. Without the existence of unity, there is no plausibility of the explanations of
this disunity. Unity of phenomenal consciousness always remains as the locus of the socalled-
disunity
Understanding the role of micro RNAs involved in seed physiology and related developmental processes using Arabidopsis thaliana as a model system
Full text linkPost embryonic life of higher plants begins with the germination of dormant seeds. Mature seeds of
most of the higher plants harbour dormant embryos and go through the complex process of
germination under favourable environmental conditions. The germination process involves dynamic
physiological, cellular and metabolic events that are controlled by the interplay of several gene
products and different phyto hormones. Micro RNAs (miRNAs) are a major class of endogenous
small non-coding RNAs of 19-22 nucleotides length. They have been implicated in various aspects
of plant development and physiology. Some miRNAs have been shown to be important in seed
development and germination. However, global expression pattern and role of miRNAs during
stages and conditions of seed germination remains elusive. Using functional genomics approach, we
have identified 58 miRNAs that are differently expressed and regulate target genes during various
stages and conditions of seed germination in Arabidopsis. Amongst them 15 differentially
expressed miRNAs were validated by quantitative Reverse Transcription Polymerase Chain
Reaction (qRT-PCR).We identified miRNA targets, annotated their functions and analyzed their
expression patterns. In majority of the cases, we observed a strong correlation between expression
pattern of miRNAs and their targets indicating role of miRNA mediated post-transcriptional gene
regulation in seed germination. Interestingly, the expression of miR390, which regulate the
production of a trans acting-small interfering RNA (ta-siRNA), called tasiR-ARF correlates with
that of Auxin Response Factor 2/3/4 (ARF2/3/4), targets of tasiR-ARF. We have showed that the
germination efficiency and viability of seeds of ta-siRNA biogenesis pathway mutant allele sgs3-
11 are significantly altered under abiotic stress conditions, suggesting that both miRNAs, ta-siRNAs
and their targets contribute to seed germination process under normal and stress conditions.
Functional characterisation of miR165/166 using target mimic line seeds (eTM-miR165/166)
suggests its role in seed viability and germination efficiency under normal and various abiotic stress
conditions
