title: Keeping free-edited textual and graphical views of information consistent

authors: Grundy, John C.

subjects: computer science

abstract: Multi-view editing is useful in many situations where users of a software application want to see and interact with different representations of the same information. This paper describes a new approach to keeping free-edited multiple textual and graphical views of information consistent. Descriptions of changes to information items are displayed in various ways in the multiple views of these items. Users can request an editing tool to automatically apply changes to a view, select a change to make from a range of possible changes, or manually implement changes to maintain view consistency. Semantic errors, user-defined changes and hierarchical changes can be represented, and this technique also supports flexible view consistency for cooperative work systems. Experience with this technique in several diverse multi-view editing environments is described.

title: Identification of fatty acid esters of pectenotoxin-2 seco acid in blue mussels (mytilus edulis) from Ireland

authors: Wilkins, Alistair L.

subjects: Dinophysis

abstract: Pectenotoxins from marine dinoflagellates of the genus Dinophysis are rapidly hydrolyzed by many shellfish to give pectenotoxin-2 seco acid, which isomerizes to 7-epi-pectenotoxin-2 seco acid. Three series of fatty acid esters of pectenotoxin-2 seco acid (PTX-2 seco acid) and 7-epi-PTX-2 seco acid were detected by LC-MS analysis of extracts from blue mussels (Mytilus edulis) from Ireland. The locations of the fatty acid ester linkages were identified by a combination of LC-MSn in positive- and negative-ion modes, LC-MS analysis of the products from reaction of the esters with sodium periodate, and NMR analysis of purified samples of the two most abundant ester derivatives. The 37-O-acyl esters of PTX-2 seco acid were the most abundant, followed by the corresponding 11-O-acyl esters, accompanied by low levels of the 33-O-acyl esters. The most abundant fatty acid esters in the fractionated sample were, in order, the 16:0, 22:6, 14:0, 16:1, 18:4, and 20:5 fatty acids, although a wide array of other PTX-2 seco acid fatty acid esters were also present at low levels.

title: Intra-propositional relations and their signalling: An investigation of authentic Māori texts

authors: Whaanga, Hēmi

subjects: Language & education

abstract: I report here on one part of a research project that involved the investigation of a range of authentic Māori texts in terms of two types of meaning relation – those that operate within propositions (‘intra-propositional relations’) and those that link propositions or groups of propositions (‘inter-propositional relations’). The focus here is on intra-propositional relations (relationships within propositions). On the basis of the comparison of a number of intra-propositional relational models, a new model which draws inspiration from the work of Crombie is proposed and applied to a corpus of texts written in Māori, the emphasis being on the ways in which these relations are signalled in Māori.
