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
Wikis: Tool for Altering Tacit Knowledge Explicit
No full textThe paper presentsives an overview of the concept and dimensions of knowledge and its management in libraries using ICT based systems. Explores how Wikis can be used in libraries to commute the implicit knowledge explicit among the professionals and the users. Discusses in detail the scope of Wikis implementation in libraries. Explains the relative advantage and weakness of Wikis as a knowledge management tool in libraries

Buthan: Pele La, 01.iii. 2002, 3200 m asl., one female (ZMAN), dissected and slide mounted in Hoyer's fluid. Morphology. Female: Idiosoma (ventral view: Fig. 9) L 862, W 669. One pair of fused dorsocentral plates (Dc- 3) (Fig. 8). Coxal field: L between anterior end of first coxae and posterior end of fourth coxae 428; L of genital valves 155; genital valves not covering the genital acetabula; posterior acetabula rounded; L of acetabula 1–3: 58-65 - 33. Capitulum (Fig. 13) L 218; chelicera (Fig. 14) L 232, H 56, L/H ratio 4.1, basal segment L 167, claw L 68, ratio chelicerae basal segment/claw L 2.5; palp (Fig. 12) total L 560, dL and %L (in parentheses, given as % of total L): P- 1 25 (4.5), P- 2 128 (22.9), P- 3 163 (29.1), P- 4 200 (35.7), P- 5 44 (7.9); P- 2 /P- 4 ratio 0.64; Ambulacrum (Fig. 11) with slightly developed claw blade, claws with clawlet. L of IV–L (Fig. 10) segments: IV – 125, 125, 139, 259, 265, 219. Remarks. Due to the presence of glandularia on Cx- 3, P- 2 with a long ventrodistal projection, and excretory pore surrounded by sclerotized ring, the specimen from Bhutan shows a general conformity with Sperchon indicus Kumar et al. Differences (in parentheses data taken from Kumar et al. 2007) are found in its major idiosoma and gnathosoma dimensions (e.g., S. indicus idiosoma L 694, genital valves L 124, capitulum L 158–181, palp total L 515–544). Furthermore the specimen from Bhutan has P- 4 less elongated and the claw blade less developed (strongly developed in S. indicus – see Kumar et al. 2007). The variability of further specimens from Bhutan needs to be known and studies on male specimens of S. indicus are necessary before we can assess the taxonomic status of this specimen. Distribution.

S. garhwalensis was described from India by Kumar, Kumar & Pesic in 2007 (Kumar et al. 2007). But in their original description, only female was described and it’s taxonomic status of the subgenus was not given. It is the first report with the first description of the male from China. The features of both male and female examined well coincide with the characteristic of the subgenus Hispidosperchon, so it should be placed in this subgenus. The decorations of cuticle, E 4 on CxIII, P- 4 shorter than P- 3 and excretory pore with a sclerotized ring in the females from China show a general conformity with S. garhwalensis Kumar, Kumar & Pesic, 2007 from India. Some differences in the body size and the number of the plates on the dorsum and venter should be regarded as the variety between the different geographical populations. FIGURE B (1–9).

Multivariate Quantitative Representativeness and Constituency Analysis of Ecological Observation Networks
Author: Jitendra (Jitu) Kumar ([email protected]), Oak Ridge National Laboratory
Regional and global ecological research networks, representing coordinated and standardized as well as adhoc networks of observation sites, provide valuable observations necessary for ecological modeling and synthesis studies. Studies conducted across observational networks strive to scale up their results to larger areas, trying to reach conclusions that are valid throughout regional, continental, and even global scales. Network representativeness and constituency can show how well conditions at those locations represent conditions elsewhere within a larger area containing the network and can be used to help scale-up results over larger regions.
Representativeness: Euclidean distance between two sites plotted in multivariate environmental space can be used as an inverse measure of multivariate similarity to quantify representativeness. Close sites in environmental space have a similar combination of environmental factors, and therefore are highly representative of each other.
Constituency: For any site in the network, its Constituency represent all locations that are best represented by the multivariate environmental drivers at that site.
