title: A projection-based solution to the SP(2N) state labeling problem

authors: Gould, M.D.

subjects: Mathematics

abstract: A projection-based solution to the symplectic group state labeling problem is presented. The approach yields a nonorthogonal Gel'fand–Tsetlin basis for the irreducible representations of Sp(2n). A method for evaluating the corresponding overlap coefficients is discussed. The action of the Sp(2n) generators, in the basis obtained, is determined and some matrix element formulas are derived. The results obtained are comparable to the matrix element formulas for O(n) and U(n).

title: Semantics in Greenstone

authors: Hinze, Annika

subjects: computer science

abstract: This chapter illustrates the impact on a well known digital library system - Greenstone - when it is moved from fixed modules and simple metadatabased structures, to open semantic digital library modules. This change has profound effects on the tools available to end-users to retrieve relevant content from the library, and an equally significant impact on the digital library (DL) architecture. Most current DL systems contain protocols for internal communication that define information exchange solely in terms of searching, browsing, and document retrieval. These communications reflect traditional user interactions in the library. However, this regimented approach results in inflexible systems that are difficult to extend to support other retrieval techniques. Furthermore, simple field-based metadata limits the ability of the DL to connect or disambiguate key items of information, impeding the precision of retrieval.

title: Māori & Psychology Research Unit Annual Report 2015

authors: Waitoki, Waikaremoana

abstract: The Māori and Psychology Research Unit (MPRU) was established in August of 1997. The Unit acts as a catalyst and support network for enhancing research concerning the psychological needs, aspirations, and priorities of Māori 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 School of Psychology, the Faculty of Arts and Social Sciences, the wider University and general community.
