title: Low-cost semantic enhancement to digital library metadata and indexing: simple yet effective strategies

authors: Hinze, Annika

subjects: computer science

abstract: Most existing digital libraries use traditional lexically-based retrieval techniques. For established systems, completely replacing, or even making significant changes to the document retrieval mechanism (document analysis, indexing strategy, query processing and query interface) would require major technological effort, and would most likely be disruptive. In this paper, we describe ways to use the results of semantic analysis and disambiguation, while retaining an existing keyword-based search and lexicographic index. We engineer this so the output of semantic analysis (performed off-line) is suitable for import directly into existing digital library metadata and index structures, and thus incorporated without the need for architecture modifications.

title: Synthesis and characterisation of organo-platinum(II) complexes of the N,O-donor ligands hippuric acid (N-benzoylglycine) and N-phenylanthranilic acid

authors: Sim, Sophie A.

subjects: Science & Technology

abstract: Reaction of [PtCl₂(cod)] (cod = cyclo-octa-1,5-diene) with either hippuric acid [PhC(O)NHCH₂COOH] or N-phenylanthranilic acid (ortho-PhNHC₆H₄COOH) in refluxing dichloromethane in the presence of silver(I) oxide gave the new organoplatinum derivatives [Pt{N(COPh)CH₂COO}(cod)] and [Pt{N(Ph)C₆H₄COO}(cod)] respectively. Ligand substitution reactions of the cod ligand in [Pt{N(COPh)CH₂COO}(cod)] provided a facile route to a selection of phosphine-substituted analogues [Pt{N(COPh)CH₂COO}L₂] [L = phosphatriazaadamantane (pta), PPh3, or L₂ = Ph₂PCH₂CH₂PPh₂ or Fe(η⁵-C₅H₄PPh₂) ₂] via displacement of the labile cod ligand. The complexes were characterised using NMR spectroscopy, IR spectroscopy, and ESI mass spectrometry. The X-ray structure of [Pt{N(COPh)CH₂COO}(cod)] is also reported.

title: Kaupapa Māori framework and literature review of key prinicples

authors: Kennedy, Nathan

subjects: New Zealand

abstract: The literature review in this report was the starting point for the development of a Māori research strand within the Planning Under Co-operative Mandates (PUCM) research programme. The original purpose of this report Kaupapa Māori Framework and Literature Review of Key Principles was to establish definitions of environmentally significant concepts of kaupapa and tikanga Māori. In  addition,  the  review  sought  to  identify  and  briefly  describe  significant  variations between  understandings of the key concepts without attempting to reconcile these. As the purpose of the review in 2005 was to inform the development of a kaupapa Māori methodology for the identification and development of Māori environmental outcomes and indicators, we paid particular regard to Māori perceptions of the environment and the relevance of each concept in environmental terms.
