title: Phylogeography and species discrimination in the Paracalliope fluviatilis species complex (Crustacea: Amphipoda): can morphologically similar heterospecifics identify compatible mates?

authors: Sutherland, Darin Lee

subjects: arthropoda

abstract: We examined the phylogeographic patterns of Paracalliope fluviatilis (Amphipoda) over its entire range and the prevalence of mate discrimination in laboratory mate choice tests using genetically distinct populations. We predicted that mate discrimination would increase as the level of genetic divergence increased between populations. Thirty different haplotypes were found with pairwise sequence divergences in the range 1–23.5% between locations. Individuals were selected from seven genetically distinct populations and males were presented with 'local' (same population) or 'foreign' (genetically divergent) females. Males were more likely to pair with local than foreign females but there was no evidence of a gradual increase in discrimination. Discrimination became most prominent (approximately 5 : 1 local : foreign) when genetic divergences exceeded approximately 20%; matings between divergent individuals also resulted in significantly fewer females producing eggs. We suggest that: (1) this abrupt shift in discrimination occurs because individuals from different, but similarly divergent, clades rely on different recognition cues (e.g. moulting pheromones with disparate chemical signatures) that trigger recognition and subsequent discrimination of incompatible mates; (2) geological history associated with sea level changes and a series of isolation events may be responsible for the patterns of discrimination that we observed; and (3) amphipods may be more genetically variable relative to other invertebrate taxa.

title: The business of the other: representing the non-west in management and media

authors: Munshi, Debashish

abstract: This thesis explores current facets of the business of the other in western management and business media discourses. It identifies the shaping of these facets through continuities between imperial colonisation and contemporary neocolonialism in ways that mainstream management discourses marginalise or ignore. In establishing marginalisation and neglect, and opening up some of the consequences, the thesis draws on conceptual frameworks from indigenous, feminist, postcolonial, and subaltern studies. In addition, it argues that this ongoing incorporation of colonial concepts and practices into contemporary neocolonialism not only needs to be acknowledged but needs to be challenged by the reconceptualisation of current approaches to the other across a number of business fields.

After analysing the process of othering in the mainstream media through a study of the New Zealand press, the thesis focuses its four main lines of inquiry on the fields of business journalism, public relations, diversity management, and intercultural communication. In particular, it looks at aspects of western control involved in the ‘globalisation’ campaigns of the western media; the theoretical formulation of ‘requisite variety’ in public relations; the rhetoric of ‘managing diversity’ in organisations; and the formulation of ‘intercultural communication’ in education.

For the first line of inquiry, the thesis analyses how western business journalism texts exercise control over the other by updating Orientalist or Eurocentric ideologies as a discursive underpinning of, and accompaniment to, neocolonial economic expansion. Its second inquiry leads to a critique of the outwardly egalitarian concept of requisite variety in public relations literature. The thesis finds that, although this concept has allowed public relations to take note of the cultural other, it has, in a largely ethnocentric field, done little to shift the balance of power away from dominant western elites. Instead, it shows how the field operates to support those who already hold privileged positions and keep those on the margin marginalised.

In the third and fourth lines of inquiry, into discourses of diversity management and intercultural communication, similar consolidations of western neocolonial power are evident. While acknowledging attempts by these fields to incorporate the other into the larger organisational frame, the thesis tracks a systematic tendency to avoid or sideline issues of socio-political power in representations of diversity. It further contends that these benign-looking discourses of diversity align with the neocolonial west’s strategies to retain power in a world where major demographic shifts are reducing western populations to a numerical minority. 

The thesis also attempts, by introducing my lived experience as an other, to synthesise subjective observations with academic analysis. This integration of lived experience with the legitimacy of theory has been crucial to the project of the thesis as a whole. That project aims to resist sites of control entrenched in western worldviews and, in the face of persistent denials that they exist, to acknowledge racism and other potent discursive and material traces of imperialism.

title: Rangatiratanga - Kawanatanga: Dealing with rhetoric

authors: Nikora, Linda Waimarie

abstract: Numbered among the few Maori appointed to an academic position during the late 1980s, I have seen our discipline and profession, in all its awkward self-consciousness, make genuine attempts to grapple the respond to questions and challenges delivered by Maori and Pakeha alike.  For example, Where is the Maori content in courses?  Why aren’t Maori graduating from professional training programmes?  Why are there not more Maori academics? Where is the place/space for Maori as practitioners, academics, researchers and decision-makers?  Why does it seem that Maori are always on the ‘client’ side of the professional/client equation?  Where are the Maori men?  In responding to these persistent challenges the professional and discipline in Aotearoa/New Zealand has been irreversibly changed, in my opinion.  The change has not been dramatic (psychology is somewhat averse to self-promotion) but, of those changes that have occurred, a definite contribution has been made to advancing Maori development, to building a more bicultural discipline and practice, and to supporting the strength of the Kawanatanga and Rangatiratanga dynamic whose importance I emphasize here.
