Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
Belonging and not belonging : understanding India in novels by Paul Scott, Ruth Prawer Jhabvala and V.S. Naipaul.
No full textPhDThis thesis is essentially about the "how" and "why" of the Indian
experience as documented in novels by Paul Scott, Ruth Prawer Jhabvala
and V S Naipaul. The study points to the difficulty of arriving at any
conclusive definition of the country and its people. I show that
differences in attitudes, responses or behaviour are both overt and
subtle, and depend upon whether the writer or the character identifies
with the situation or community with which he or she interacts. It is
the individual's sense of belonging or not belonging to his or her own
group - be this along racial, cultural or gender lines - that accounts
for the differing perspectives evident in these novels. The points-of-
view of the outsider and the insider can therefore be seen as
mutual comments upon the other.
Since the struggle between belonging and not belonging becomes acute
when the old meets the new, focus is centred on communities
experiencing change. These include the British in India, West-Indian
Indians and westernised Indians. Despite their differences, all three
communities share similar reasons for either an acceptance or
rejection of the 'Other'. The thesis argues that the need for
emotional stability compels allegiance to the traditional group, while
the desire for individuality encourages surrender to the new. The
former nurtures a sense of belonging while, it is argued, that the
latter is perceived as the hallmark of those who do not belong.
Tensions arise when both these needs demand to be met. What I show to
be ironic in this struggle between belonging and not belonging is that
those things which individuals overtly reject are often unexpressed
parts of their personal pysche. The barrier between "them" and "us" is
therefore very fragile

No full textTransforming traditional libraries into Digital Libraries
No full textInformation Technology (IT) developments have changed the ICAR, ICMR and CSIR Institutes' libraries over the last few decades and speculates about further changes to come. The study discussed a 3 phase procession of the effects of IT on organization: modernization, innovation and transformation. The first stage of the study is to dominate by the theme of computerization of library applied a growing range of IT in the management of collection of primarily print on agriculture, industry and medical science information. The second stage is the rise of public access through LAN and WAN shared information it's resulted that Public Access Cataloguing (PAC), abstracting and indexing databases (CDRom database) had become quite large as a result of respective conversion programs for older books and some years of use in cataloguing new acquisitions. The development of automation age, print content goes electronic, online catalogue through widely popular rapidly created demand for actual content in digital form. The third stage is the innovation and transformation of information the institutions characterized by an enormous, exhilarating flowering of innovation, creativity and experimentation. The libraries must turn their attention to defining their mission and activities in relationship to their transforming information. Numerous troubles some issues had already encountered. High cost, pricing, licesing copy right, uninterrupted online access, perpetual access to back issues etc. will be much harder and more challenging issues

Tracking the evolution of photoexcitations in strongly light absorbing systems
No full textAuthor requested closed access (OA after 2yrs) in Vireo ETD systemLimitedThis dissertation consists of the work done towards a Ph.D. degree in the research group of Professor Prashant K. Jain at the University of Illinois at Urbana-Champaign. Here, I describe the study of the conversion of light energy using hybrid perovskite and noble metal-based semiconductor nanoparticles. The large surface-area-to-volume ratios and superlative ability to absorb visible light make these materials worthy candidates for solar energy harvesting. The primary questions I have asked in my research are: what is the fate of photoexcitation in a nanostructured material and how can we channel such photo-excitations in an efficient and selective manner? Chapter 1 of this dissertation introduces some of the theoretical backdrops to my studies of strongly light-absorbing plasmonic nanoparticulate systems. This chapter elucidates what follows and introduces the concepts and terms used. Chapter 2 presents my investigation of hybrid organic-inorganic perovskite materials for potential uses towards light trapping and emission. We discovered that commonly observed luminescence from microcrystals of these materials showed a spectrum that varied with sample morphology and location on the sample. The origin of this spectral heterogeneity was then traced to the phenomenon of luminescence self-absorption, which is prevalent due to the overlapping absorption and emission, i.e., small Stokes-shift, in these materials. Then we explored light-to-chemical-energy conversion in perovskite materials, but they proved to be photochemically unstable; so, we turned our attention to noble metal nanoparticles, which have strong plasmon resonance absorption and high photostability. Chapter 3 describes the investigation of light-to-chemical energy conversion in colloidal gold (Au) nanoparticles In particular, we studied the effect of visible-light excitation of Au nanoparticles in the presence of an electron acceptor (HAuCl4) and a hole acceptor (short-chain alcohol). This led to the discovery of a hitherto unknown photoreaction, which involves the splitting and chlorination of the alcohol
generating a chloroalkane and an aldehyde. This reaction was found to take place with several alcohols, which led us to a general reaction mechanism that is catalyzed synergistically by the photoexcited nanoparticle and the Lewis acidic HAuCl4. In the specific case of 2-butanol as the hole acceptor, we found a substantial difference between the product distributions of the light-driven reaction as compared to a thermal reaction. This finding represents an example of light-driven-control of catalytic selectivity. Finally, as presented in Chapter 4, the insights gained from the study described in Chapter 3 led me to a new, simple chemical process for low-temperature chlorination of methane in a non-corrosive aqueous environment. The kinetics and mechanism of this reaction were studied. Methane chlorination is at the heart of natural-gas upgradation, so this new finding represents an ideal culmination of my dissertation. An outlook and potential future directions are presented in Chapter 5.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-12-01The student, Varun Mohan, accepted the attached license on 2020-12-01 at 18:31.The student, Varun Mohan, submitted this Dissertation for approval on 2020-12-01 at 18:50.This Dissertation was approved for publication on 2020-12-04 at 10:01.DSpace SAF Submission Ingestion Package generated from Vireo submission #16022 on 2021-03-04 at 16:33:11Made available in DSpace on 2021-03-05T21:47:26Z (GMT).
