Experimental nasopharyngeal colonization by Neisseria meningitidis using explant organ culture
No full textThis chapter will describe the use of organ cultures of human nasopharyngeal mucosa to study the interaction of Neisseria meningitidis with this complex tissue. Colonization of nasopharyngeal mucosa is the first step in the pathogenesis of meningococcal disease. Supporting evidence for this is the correlation between the prevalence of community carriage and the occurrence of meningococcal disease (1). During nonepidemic periods, the baseline prevalence of nasopharyngeal carriage of meningococci is 5-10% but is considerably higher in certain populations such as military personnel (2), and in households of cases (3). There are a number of influences on the acquisition of meningococcal carriage; these include smoking (4) but not season (5). It is possible that coincident viral infections may affect acquisition of meningococ cal carriage (6,7). There is good evidence that genetic factors are involved, as some individuals appear resistant to acquisition of carriage, while others chronically or intermittently carry N. meningitidis (8). Carriage of the organism also appears to be associated with secretor status (9). The precise site within the nasopharynx that Neisseria meningitidis colonizes and invades is not known. However, during natural carriage, the organism can be isolated both from the rhinopharynx and from the throat (10).</p
Using Authentic Literature to Enrich Young Children\u27s Literacy Experiences
No full textThis article focuses on the five components (phonemic awareness, phonics, fluency, vocabulary, and comprehension) needed to effectively teach children to read. Early childhood educators can teach these five skills through the use of authentic literature. To be classified as authentic literature, books and texts need to utilize “real life” writing that is written to engage the reader. Authentic narrative texts generally appeal to the reader and offers a theme and a moral to the story. The article explains the five components needed to teach children to read and offers some authentic texts, synopses, and lesson ideas specifically for each of the components. Although children may not be able to read the texts, the texts selected are at the child’s listen-ing comprehension level. In addition, the selected texts will aid early childhood educators and parents in infusing these skills for engaging implementation
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Designing role-based view for object-relational databases
No full textIn a federated database system, a view mechanism is crucial since it is used to define exportable subsets of data ; to perform a virtual restructuring d ataset; and to construct the integrated schema. The view service in federated databa se systems must be capable of retaining as much semantic information as possible. The object-oriented ( 0 - 0 ) model was considered the suitable canonical data model since it meets the original criteria for canonical model selection. However, with the emergence of stronger object-relational (0 -R ) model, the re is a clear argument for using an 0 - R canonical model in the federation. Hence, research should now focus on th e development of semantically powerful view mechanism for th e newer model. Meanwhile, the availability of real 0 -R technologies offers researchers the opportunity to develop different forms of view mechanisms.
The concept of roles has been widely studied in 0 - 0 modelling and development. The role model represents some characteristics that the traditional 0-0 model lacked, such as object migration, multiple occurrences and context-dependent access. While many forms of 0-0 views were designed for the 0-0 canonical model, one option was to extend the 0-0 model to incorporate a role model. In a role model, the real entity is modelled in the form of a role rather than an object. An object represents the permanent properties of an entity is a root object; and an object represents the temporary properties of an entity is a role object.
The contribution of this research is to design a view system that employees the concept of roles for the 0 -R canonical model in a federated database system. In this thesis, an examination of the current 0 -R metamodel is provided first in order to provide an environment for recognising the roleview metadata and measuring the view performance; then a Roleview Definition Language (RDL) is introduced, along with the semantics for defining virtual classes and generating virtua l extents; finally, a working prototype is provided to prove th e role-based view system is implementable and the syntax is semantically correct
Reading in the mobile era
No full textMobile technology can advance literacy and learning in underserved communities around the world.
Summary
Millions of people do not read for one reason: they do not have access to text. But today mobile phones and cellular networks are transforming a scarce resource into an abundant one.
Drawing on the analysis of over 4,000 surveys collected in seven developing countries and corresponding qualitative interviews, this report paints the most detailed picture to date of who reads books and stories on mobile devices and why.
The findings illuminate, for the first time, the habits, beliefs and profiles of mobile readers. This information points to strategies to expand mobile reading and, by extension, the educational, social and economic benefits associated with increased reading.
Mobile technology can advance literacy and learning in underserved communities around the world. This report shows how
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

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
