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

Ling-Zhi Polysaccharides Potentiate Cytotoxic Effects of Anticancer Drugs against Drug-Resistant Urothelial Carcinoma Cells
No full textThe combined effects of ling-zhi polysaccharide fraction 3 ( LZP-F3) and anticancer drugs (cisplatin and arsenic trioxide) were examined in three human urothelial carcinoma (UC) cells (parental, NTUB1; cisplatin- resistant, N/P(14); and arsenic-resistant, N/As(0.5)). MIT assay and median- effect analysis revealed that LZP-F3 could profoundly reverse the chemosensitivity of NIP(14) and N/As(0.5) to cisplatin and arsenic, respectively, in a dose-dependent manner, which involved activation of p38 and down-regulation of Akt and XPA. A dose of 10 mu g/mL of LZP-F3 induced significant G1 arrest in NIP(14) and N/As(0.5) cells by flow cytometry, which may be mediated by the induction of p21( WAF1/CIP1). The combination of LZP-F3 and arsenic trioxide produced a significant synergistic growth inhibition of NTUB 1 and N/As( 0.5) cells. Similar results were also found in N /P(14) cells. These molecular events of combined effects involved significant and earlier induction of Fas, caspase 3 and 8 activation, Bax and Bad up-regulation, Bcl-2 and Bcl- x(L) down-regulatuion, and cytochrome c release
Data for: Sea urchin control of macroalgal communities across a productivity gradient

"Procedural_control_octocoral_graer-exclusion_experiment_PPB.xlsx"Data set (1.) contains survey data - point intercept counts of macroalgae across 3 distinct environmental zones of Port Phillip Bay in Oct/ Nov 2013. Percentage cover of macroalgae was assessed visually by inspecting algae present at each of 50 intersecting points (defined by the intersection of perpendicularly strung wires) within five 0.5 m by 0.5 m metal quadrats placed at 10 m intervals along a single 50 m transect line laid at each of 6 sites within each of the environmentally distinct zones during Spring (October/ November). The intersecting points were then multiplied by two to obtain percentage cover estimates for each macroalgal taxa (resolved to species-level where possible, or genera-level). The total number of intersecting points counted could exceed 50 points (i.e. >100% cover) as algal taxa composing the overstory, understory and substratum were assessed.Data set (2.) contains co-variates concurrently measured at each survey transect in data set (1.).Data set (3.) contains data for the pilot octocoral grazer-exclusion experiment.

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
