title: Categories of insight and their correlates: An exploration of relationships among classic-type insight problems, rebus puzzles, remote associates and esoteric analogies.

authors: Cunningham, J. Barton

subjects: insight problem solving

abstract: A central question in creativity concerns how insightful ideas emerge. Anecdotal examples of insightful scientific and technical discoveries include Goodyear's discovery of the vulcanization of rubber, and Mendeleev's realization that there may be gaps as he tried to arrange the elements into the Periodic Table. Although most people would regard these discoveries as insightful, cognitive psychologists have had difficulty in agreeing on whether such ideas resulted from insights or from conventional problem solving processes. One area of wide agreement among psychologists is that insight involves a process of restructuring. If this view is correct, then understanding insight and its role in problem solving will depend on a better understanding of restructuring and the characteristics that describe it.
This article proposes and tests a preliminary classification of insight problems based on several restructuring characteristics: the need to redefine spatial assumptions, the need to change defined forms, the degree of misdirection involved, the difficulty in visualizing a possible solution, the number of restructuring sequences in the problem, and the requirement for figure-ground type reversals. A second purpose of the study was to compare performance on classic spatial insight problems with two types of verbal tests that may be related to insight, the Remote Associates Test (RAT), and rebus puzzles. In doing so, we report on the results of a survey of 172 business students at the University of Waikato in New Zealand who completed classic-type insight, RAT and rebus problems.

title: Mode I and Mode II interlaminar fracture toughness of composite laminates interleaved with electrospun nanofibre veils

authors: Beckermann, Gareth W.

subjects: Science & Technology

abstract: In this study, the effects of interleaved nanofibre veils on the Mode I and Mode II interlaminar fracture toughness (ILFT) of autoclave cured unidirectional carbon/epoxy composite laminates were investigated. Various electrospun nanofibre veils consisting of a range of different polymer types, fibre diameters and veil architectures were placed in the laminate mid-planes, which were subsequently subjected to double cantilever beam and end-notch flexure tests. It was found that the polymer type and veil areal weight were the most important factors contributing to laminate performance. A 4.5 g/m2 PA66 veil provided the best all-round performance with fracture toughness improvements of 156% and 69% for Mode I and Mode II, respectively.

title: Nga taonga o Te Urewera

authors: Te Awekotuku, Ngahuia

subjects: Maori

abstract: This report sets out to establish that Te Urewera and Tuhoe - the place, the people -
are synonymous. It is argued by two discrete approaches - cultural property and the
significance of place. These are both enmeshed in the Tuhoe concept of
matemateaone, which is defined and demonstrated throughout the text. Issues of
Tuhoe heritage and cultural property are positioned within the international
indigenous context, and considered in detail with reference to the United Nations
Report on the Protection of the Heritage of Indigenous Peoples tabled in June 1995.
A Tuhoe response to the nine sections of this document form the basis of this
submission, as they clearly reflect the intentions and principles that configure the
articles of the Treaty of Waitangi.
