title: International migration in New Zealand: Context, components and policy issues

authors: Bedford, Richard

subjects: population

abstract: This paper explores Aotearoa/New Zealand’s distinctive heritage as both a ‘traditional land of immigration’ as well as a ‘country of emigration’, with particular reference to contemporary policy issues and research initiatives. An underlying theme of the argument is the need for an approach which takes account of all types of movement into and out of the country when researching immigration, both as a process and as a policy domain.

title: Internal fibre length concentration in a pressure screen

authors: Atkins, Martin John

subjects: pressure screening

abstract: Localised axial consistency profiles within a pressure screen of a Pinus Radiata kraft pulp are reported. Axial Samples were also analysed using a Kajaani FS-200 to obtain fibre length distribution data. Localised consistency in the feed annulus was found to vary considerably and the consistency was found to be less than the feed consistency over some portions of the screen (annular dilution). Changes in consistency along the accept side was fairly constant although subtle changes were observed. 
Pulp passage ratios for both the bulk and individual fibre length fractions were calculated using the consistency profiles and fibre length data. In all cases fibre passage decreased along the screen length. Fibre passage was affected by a position effect which is comprised of two factors: flocculation effects, and flow and rotor effects. Fibre fractionation efficiency was found to increase along the length of the screen. 
Mechanisms that account for the observed annular dilution, passage ratio and efficiency changes are proposed. These involve flow of both fluid and fibre in the forward and reverse directions across the screen plate, increased flocculation in the feed annulus and the slip velocity between incoming pulp and the rotor tip.

title: Maori Flourishing in a Fast Changing World - Inaugural Professorial Address

authors: Nikora, Linda Waimarie

subjects: Indigenous psychology; Maori flourishing; social identity; social and emotional wellbeing

abstract: A strong sense of who one is and that one’s life matters is vital to health and wellbeing. Without meaning and belonging many people, families and communities lie open to the risk of mental illness, addiction, transience, criminality, suicide and so on. In a rapidly changing social and technological environment where being Maori is enacted in the face of a dominant Pakeha majority, and in an increasingly diverse Maori world, staying well is an important challenge that we cannot underestimate or take for granted. There are many unwellness forces upon Maori in this fast changing world. Some are obvious and readily felt, others not so easy to apprehend or explain. Surveying almost 30 years of research, Professor Nikora will examine some of these unwellness forces and responses Maori make within the broader quest to remain indigenous and to flourish.
