title: Characteristics of proteinases and lipases produced by seven Bacillus sp. isolated from milk powder production lines

authors: Chen, L.

subjects: Bacillus species

abstract: Seven Bacillus strains isolated from milk powder production lines were grown in two selective media. All the strains produced extracellular and intracellular proteinase and lipase activity, but at different levels. Proteolytic activity was generally highest at neutral to alkaline pH. Inhibitor studies showed that two types of proteinase were produced — a serine proteinase and a metallo-proteinase. Not all of the strains produced both types of activity and those that did produced different levels. All strains produced a 1,3-specific lipolytic activity that showed a preference for short-chain fatty acids. The lipolytic activity had greater heat stability than the proteinase activities, but all would clearly survive pasteurisation at 72°C for 2 min in milk. Further, the enzymes are likely to survive any heat treatments applied during commercial milk powder manufacture. The enzymes remain active in milk powder during storage, and are therefore likely to be active in milk products made from recombined milk powder.

title: Diasporic films and the migrant experience in New Zealand: A case study in social imagination

authors: Zalipour, Arezou

subjects: Asian diaspora

abstract: Drawing upon interviews and focus groups with Asian migrants, this article interrogates responses to ‘diasporic’ films that seek to represent multicultural experiences in contemporary New Zealand. We argue that these responses provide an effective demonstration of the operation of the ‘social imagination’, a discursive process that articulates the fundamental linkage between symbolic representation, community formation and social action. As our respondents narrated the personal meanings that they construct around ethnically specific media, they were compelled to describe known and hypothetical others, to elucidate symbolic and moral codes, and to reveal social empathies and anxieties. In this study, we found that discussions around migrant stories revealed a series of deeply personalised notions of self and place that were always situated in juxtaposition with externalised projections of community formation and the ‘mainstream’ culture. This dynamic reflects what can be conceptualised as the central preoccupations of a ‘diasporic social imagination’. These responses, therefore, constitute a case study of social imagination at work in a multicultural context, underlining the utility of narrative media in providing a public forum for discussing cultural diversity.

title: Mā hea (which way)? Mō te aha (what for)? Too many questions, not enough answers, for Māori on the march

authors: Te Awekotuku, Ngahuia

subjects: Aotearoa/New Zealand

abstract: This presentation will be in four sections. The first section introduces two major issues: mana motuhake, and mana tāngata, then we will consider some proposed legislation: the Foreshore and Seabed Bill and the Civil Union Bill. Then I will look at strategic Māori responses to political pressure over the last three decades and note two recent and dramatic examples – the Hīkoi Takutai Moana, April 2004, and the Enough is Enough Rally, August 2004. The final section considers the implications for psychologies and psychologists working today in Aotearoa.
