Domain-specific backlinking services in the Web of Data
No full textThis paper describes an Open Linked Data back- linking service, a generic architecture component to support the discovery of useful links between items across highly connected data sets. Using Public Sector Information (PSI) currently available as Linked Data, we demonstrate that contemporary publishing practices do not adequately support the ability to navigate or automatically traverse between resources published by different vendors, or the capacity to discover information relevant to a particular URI. Although some useful services in this area have been developed, such as large triple indexes of published data, and the collection of sameAs relationships between individuals, we believe that an important component is missing: a mechanism to discover the backlinks to relevant resources that cannot be found by direct URI resolution. We present the implementation of such a component, integrating data from various PSI sources

From Information to Sense-Making: Fetching and Querying Semantic Repositories
No full textInformation, its gathering, sharing, and storage, is growing at a very rapid rate. Information turned into knowledge leads to sense- making. Ontologies, and their representations in RDF, are increasingly being used to turn information into knowledge. This paper describes how to leverage the power of ontologies and semantic repositories to turn today’s glut of information into sense-making. This would enable better applications to be built making users’ lives easier and more effective

Managerial business qualifications, organizational performance and managerial behavior - evidence from Australia
No full textIn this article, we assess the operational impact of tertiary qualifications in business of senior managers experienced by organizations led by them, as opposed to those led by managers without such qualifications. We find that business qualifications coincide with various significant differences in the area of business planning and occupational health and safety systems. Overall, however, the level of performance of firms between the two groups does not vary significantly. © John Rice, Nigel Martin, Sasikala Rathnappulige, 2009.John Rice, Nigel Martin, Sasikala Rathnappulig
Synthetic studies towards pinguisone
No full textThe novel structure and antifeedant activity of the furanosesquiterpene pinguisone make it an interesting synthetic target. The approach described in this work involves a [4+2]cycloaddition as the key reaction in constructing the correct indene skeleton. Whereas 1-methoxy-3-trimethyl-siloxybuta-1,3-diene (Danishefsky's diene) was completely unreactive towards 2,3,4-trimethyl-2-cyclopentenone, Diels-Alder cycloaddition was found to occur at very high pressure (13-15 kBar) with the more reactive dienophile methyl 2,3-dimethyl-5-oxo-1-cyclopentene-1-carboxylate giving after hydrolysis (3R*,3aS*,7aR*)-methyl 3,3a-dimethyl-1,5(4H)-dioxo-2,3,3a,7a-tetrahydroindene-7a-carboxylate in good yield. The structure of this was confirmed by X-ray diffraction. Reaction of the lithium enolate of the diene with the more reactive dienophile at low temperatures gave one Michael addition only; however, the resulting ketoester was converted to the desired indene intermediate in a good overall yield. Model studies provided a route which when applied to the indene intermediate enabled an efficient conversion (3R*,3aS*,7aS*)-2,3,3a-7a-tetrahydro-3,3a,7a-trimethylindene-1,5(4H)-dione. Conjugate addition with lithium dimethylcuprate gave the undesired epimer exclusively which on further elaboration gave 4-epipinguisone and 4-epipinguisanol. (D71565/87) he undesired epimer exclusively which on further elaboration gave 4-epipinguisone and 4-epipinguisanol. (D71565/87)</p
