title: Triangular Bézier sub-surfaces on a triangular Bézier surface

authors: Chen, Wenyu

subjects: composition

abstract: This paper considers the problem of computing the Bézier representation for a triangular sub-patch on a triangular Bézier surface. The triangular sub-patch is defined as a composition of the triangular surface and a domain surface that is also a triangular Bézier patch. Based on de Casteljau recursions and shifting operators, previous methods express the control points of the triangular sub-patch as linear combinations of the construction points that are constructed from the control points of the triangular Bézier surface. The construction points contain too many redundancies. This paper derives a simple explicit formula that computes the composite triangular sub-patch in terms of the blossoming points that correspond to distinct construction points and then an efficient algorithm is presented to calculate the control points of the sub-patch.

title: Commercial bank load loss recoveries

authors: Hess, Kurt

subjects: banking

abstract: We present a new approach to analyse historical recovery rates on distressed bank assets. Our approach uses banks’ reported impaired assets and the corresponding specific provisions. The dynamics and drivers of this credit loss recovery proxy are studied for a comprehensive sample of Australian banks from 1989 to 2005. We find that macroeconomic and bank-specific factors influence banks’ estimates of loan loss recoveries, consistent with banks smoothing their earnings. In contrast with findings based on prices of distressed corporate bonds, banks record lower recoveries in years of strong economic growth.

title: Claiming spaces: Maori (indigenous persons) making the invalid valid

authors: Hickey, Huhana

subjects: Maori

abstract: Identity is a shifting paradigm because of the constant movement between identities throughout our lives, depending on the context within which we are identifying ourselves. Once we identify, we place ourselves within a certain construct. When positioning within identity labels, multiplicitous experiences of marginalisation need to be accounted for in clarifying identity frameworks. Barile (2000) asserts that it is the multiple minority status of persons of minority ethnic identity with disabilities that positions them into multiple minority discriminatory experiences with greater limitations and discrimination than those with a single minority status identity. Barile (2000) also asserts that it challenges ethnic minority people with disabilities who work collectively and as a group where they are forced to work as individuals, often in isolation from their ethnic and cultural communities.
