title: Detection of thin tephra deposits in peat and organic lake sediments by rapid X-radiography and X-ray fluorescence techniques

authors: Lowe, David J.

abstract: This paper reports the application of the X-ray image process of X-radiography to unopened, small diameter organic sediment cores containing thin tephra deposits. Second, a rapid technique for detecting tephra layers in peat samples by X-ray fluorescence (XRF) analysis is described.

title: Revising Z: semantics and logic

authors: Henson, Martin C.

subjects: computer science

abstract: We introduce a simple specification logic Zc comprising a logic and semantics (in ZF set theory). We then provide an interpretation for (a rational reconstruction of) the specification language Z within Zc. As a result we obtain a sound logic for Z, including the schema calculus. A consequence of our formalisation is a critique of a number of concepts used in Z. We demonstrate that the complications and confusions which these concepts introduce can be avoided without compromising expressibility.

title: Maori & Psychology Research Unit annual report 2007

authors: Rua, Mohi

subjects: Maori and Psychology Research Unit

abstract: Annual report of the Maori and Psychology Research Unit (MPRU) 2007. The unit was established in August of 1997. The unit is designed to provide a catalyst and support network for enhancing research concerning the psychological needs, aspirations, and priorities of Maori people. The MPRU is well situated to draw together skilled and experienced interdisciplinary research groups by networking and establishing working relationships with staff and students within the Faculty of Arts and Social Sciences, the University, and the wider community.
