    In the current study, we explore the influence of orthographic knowledge on phonological awareness in children with cochlear implants and compare developmental associations to those found for hearing children matched for word reading level or chronological age. We show an influence of orthographic knowledge on syllable and phoneme awareness in deaf and hearing children, but no orthographic effect on rhyme awareness. Nonorthographic rhyme awareness was a significant predictor of reading outcomes for all groups. However, whereas receptive vocabulary knowledge was the most important predictor of word reading variance in the cochlear implant group, rhyme awareness was the only important predictor of word reading variance in the reading level matched hearing group. Both vocabulary and rhyme awareness were equally important in predicting reading in the chronological age-matched hearing group. The data suggest that both deaf and hearing children are influenced by orthography when making phonological judgments, and that phonological awareness and vocabulary are both important for reading developmen

    Prestressed concrete is a highly being used material in the construction of strategic and important structures such as nuclear containments, bridges, storage structures and military bunkers. It is highly durable, fire and corrosion resistant and nonporous. In order to study the influence of prestresing on the ballistic characteristics of concrete targets ballistic experiments have been carried out against ogival nosed (3 CRH) hard steel projectiles. The projectile of 0.5 kg mass were normally impacted on 80 mm thick presstressed concrete targets of plan size 450 mm x 450 mm. The unconfined compressive target strength of concrete was designed 48 MPa. An initial stress of 10% magnitude of compressive strength was induced by 4 mm diameter high tensile strength (1700 MPa) steel wires in prestressed concrete targets. A grid of 8 mm diameter steel bars were inserted in the reinforced and prestressed concrete targets to enable the straight comparison between these concretes. The prestressing in concrete has been found to be effective in reducing the volume of scabbed material as well as the ballistic resistance of prestressed concrete targets. The ballistic limit of prestressed concrete with 10% induced stress was found to be 10.2 % higher than that of the reinforced concrete and 14% higher than the plain concrete target, respectively

    Genetic variation at the apolipoprotein B gene and associations with coronary heart disease and its factors.

    PhDCoronary heart disease (CED) is the major cause of mortality in Western societies. The main risk factors are plasma lipoprotein concentrations, smoking, blood pressure and family history. The effect of family history implies a genetic contribution to the aetiology, support for which has also come from twin, and other heritability studies. The genetic component of CHID may be studied by the candidate gene approach, whereby the genes of products most likely to be involved in the processes leading to CHD, and in its risk factors, are analysed. The plasma concentration of apolipoprotein (apo) B, the major protein component of low density lipoprotein (LDL), is positively correlated with the risk of developing CHD. In this research, the gene for apo B was analysed for restriction enzyme fragment length polymorphisms (RFLPs). A RFLP is caused by a sequence change in the DNA, and results in length variation in the fragments. RFLPs for apo B have been shown to be associated with CHD and the plasma concentrations of cholesterol, triglycerides and apo B in some population studies. However, other studies have failed to confirm these relations. The work described in this thesis was designed to overcome some of the problems which niay have produced these inconsistencies. A random sample of 300 men, aged 49-65 years, residing in South Wales was studied. RFLPs determined in these individuals were used to generate genotypes and haplotypes (arrangements of specific alleles on a single chromosome). Significant associations were found between some genotypes and some haplotypes with altered concentrations of plasma total cholesterol and LDL cholesterol and with risk of CHD and/or with obesity. Presence of Xbal site (X2X2 genotype) was significantly associated with higher concentrations of plasma LDL cholesterol (p=0.0 19). Absence of Mspl site (M 1) was associated with significantly elevated concentrations of plasma total and LDL cholesterol (p < 0.05) by both the techniques of genotype and haplotype analysis. EcoRl RFLP (absence of the site - El) was the minimum haplotype necessary to detect a significant association with decreased plasma cholesterol J Rajput- Williams Ph. D. Thesis Page 3 concentrations (p < 0.05). Genotypes generated from alleles defined by the Mspl-EcoRl RFLPs were associated with significant variation in serum cholesterol concentration (p < 0.03), showing a stratification of concentration with the highest being associated with loss of the Mspl site and the lowest with the presence of the EcoRl site. Both these RFLPs result in charged aminoacid alterations, and lie close to the LDL receptor binding domain of apo B. The minimum haplotype necessary for detection of apo B with CHD was Xbal-Mspl (p < 0.05). The minimum haplotype associated with obesity was the RFLP pair Pvull-Xbal (p < 0.05). Further examination for mutations of the CpG dinucleotide which may influence cholesterol metabolism was undertaken by screening around the putative LDL receptorbinding domain (RBD) of the apo B gene. One variant was detected for aminoacid residue 3500 (Arg,,,,, 4 Gln) mutation, and two variants for aminoacid residue 3611 which also corresponds to the MspI mutation (Arg,,, ,4 Gln)

    OntoFast: Construct ontology rapidly

    No full text
    Ontology construction is a time consuming and labor intensive task. It may take many months to construct an ontology as according to standard practices each concept must have synonyms, domain specific definition, unique identifier and references. Current practices of ontology construction require manual data input to feed this data via programs such as Protégé etc. We designed a small application that speeds up the development of new ontologies. It provides an easy to use and convenient interface that allows to theoretically build an ontology within few days. The output of our program can be easily opened and then used into a standard ontology editor like Protégé.

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We 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
