title: An analysis of usage of a digital library

authors: Jones, Steve

subjects: computer science

abstract: As experimental digital library testbeds gain wider acceptance and develop significant user bases, it becomes important to investigate the ways in which users interact with the systems in practice. Transaction logs are one source of usage information, and the information on user behaviour can be culled from them both automatically (through calculation of summary statistics) and manually (by examining query strings for semantic clues on search motivations and searching strategy). We conduct a transaction log analysis on user activity in the Computer Science Technical Reports Collection of the New Zealand Digital Library, and report insights gained and identify resulting search interface design issues.

title: Commentary on “An alternative to working on machine consciousness”, by Aaron Sloman

authors: Legg, Catherine

subjects: consciousness

abstract: A commentary on a current paper by Aaron Sloman where he argues that in order to make progress in AI, consciousness (and other such unclear concepts of common-sense regarding the mind), "should be replaced by more precise and varied architecture-based concepts better suited to specify what needs to be explained by scientific theories". This original vision of philosophical inquiry as the mapping out of 'design-spaces' for a contested concept seeks to achieve a holistic, synthetic understanding of what possibilities such spaces embody and how different parameters might structure them in nomic and highly inter-connected ways. It therefore does not reduce to either "relations of ideas" or "matters of fact" in Hume's famous dichotomy. It is also shown to be in interesting ways the exact opposite of the current vogue for 'experimental philosophy'.

title: Water Quality Modelling of Te Waihora/Lake Ellesmere

authors: Hamilton, David P.

abstract: As a component of work to contribute towards the management of water quality of Te Waihora/Lake Ellesmere, the University of Waikato was subcontracted by University of Otago to apply a coupled hydrodynamic-water quality model to the lake. The primary funder for this work was Environment Canterbury (ECAN), Whakaora Te Waihora and the Central Government Freshwater Cleanup Fund. The main modelling tool used in the study to simulate the dynamics of Te Waihora/Lake Ellesmere was the one‐dimensional (1‐D) hydrodynamic-water quality model DYRESM-CAEDYM. The model was used to reproduce observed water column data for a mid-lake station over the period 2011 to 2015. Once a satisfactory level of reproduction of these data had been achieved, an assessment was carried out with the model to examine the impact of various management scenarios on lake water quality. These scenarios involved: (i) projected changes to external nutrient loads to the lake that could be associated with future land management in the catchment and (ii) different lake water level management regimes based around opening of the barrier separating the lake from the ocean. The scenarios are intended here to be a catalyst for further hui and consultations that may adapt and refine additional scenarios, some of which may involve testing of multiple management options. The quantitative output from the model provides a component of the input required to inform strategies for lake management, alongside historical and expert knowledge, as well as analysis of measured data.
