title: Miocene isotope zones, paleotemperatures, and carbon maxima events at intermediate water-depth, Site 593, Southwest Pacific

authors: Cooke, Penelope J.

subjects: Tasman Sea

abstract: Oxygen and carbon isotopic stratigraphies are presented from both benthic and planktic foraminifera for the late early Miocene to earliest Pliocene interval (c. 19–5 Ma) of intermediate water-depth DSDP Site 593 in the southern Tasman Sea. The benthic values are interpreted as recording Miocene Southern Component Intermediate Water, while the planktic species record the Miocene mode and surface water signals. Comparisons are made between temperate Site 593 and the intermediate-depth polar Site 747 in the southern Indian Ocean. Glacial Mi zones Mi1b–Mi6, representing extreme glacial events, are evident in both the Site 593 intermediate and surface water records. Miocene Southern Component Intermediate Water δ18O values are generally lighter than the Holocene equivalent (Antarctic Intermediate Water), indicating slightly warmer intermediate waters and/or less global ice volume. The benthic-planktic gradient is interpreted as indicating a less stratified Tasman Sea during the Miocene. The benthic δ13C record contains most of the global carbon maxima (CM) events, CM1–7 (CM1–6 = the Monterey Excursion). Like global deep-water records, the Tasman Sea intermediate water δ13C values indicate that most CM events correspond with Mi glacials, including Mi4 at Site 593, not reported previously. Intermediate waters play an important role in propagating climatic changes from the polar regions to the tropics, and the Site 593 dataset provides a full water column record of the structure of Miocene intermediate to surface watermasses prior to the modern situation.

title: Investigating the Journalistic Field:The Influence of Objectivity as a Journalistic Norm on the Public Debate on Genetic Engineering in New Zealand

authors: Rupar, Verica

subjects: Journalism

abstract: This thesis explores the relationship between journalism as a specific type of socio-cultural practice and the production of meaning in public discussion. Through a case study of newspaper coverage of the issue of genetic engineering in New Zealand (2001-2002), it specifically examines journalists' newsgathering methods, their use of sources and their story-telling frames, and analyses how the news media uses the norm of objectivity to shape public debate on contentious issues. 

The study argues that elements and structures of journalistic practice both determine a newspaper's ability to address events and issues in a meaningful way and define a newspaper's potential to create a space for public debate. Drawing on field theory, discourse studies and the sociology of journalism, the thesis develops a new operational framework for investigation of journalistic practice by looking at the ideal of objectivity as a method of news gathering, an account of representing reality, and an attitude towards the reality so constructed. This framework is applied in the case study of newspaper coverage of the GE issue where four components of journalistic practice are analysed: journalistic form, transparency of newsgathering, sources and frame. Using content analysis, discourse analysis, interviews and a survey, the thesis explores the relationship between journalistic norms around these elements of the practice and the discursive potential of the news text to represent, interpret and construct reality.

The findings of this study highlight the tension between outmoded forms of practice and the complexity of issues in the public domain. The analysis reveals how the norm of objectivity, originally developed as a shield for the defence of the autonomy of the profession to mediate reality, became, in the case of media coverage of genetic engineering, an obstacle in extending journalism's potential to contribute to public debate. As a method, objectivity failed to provide a set of transparent protocols for the representation of the issue in the public arena; as an account, it reflected the impossibility of separating 'facts' from 'views' and positions of detachment from those of partisanship; and as an attitude, objectivity was endangered by the increasing power of economic imperatives in the production of news.  Following this analysis, the thesis explores the influence of journalistic norms on public debate by looking at journalism as a text, as a discursive practice and as a field of cultural production.  The GE issue, constructed in the New Zealand press as a key component of the 'knowledge economy', drew attention to the dynamics between the economic imperatives
and professional standards of the journalistic field.  The objectivity norm was reduced in news reports to reporting 'what people say' rather than what the issue or argument meant, which led to a simplification of the genetic engineering issue in the public domain. The study concludes with the call for a re-examination of the journalistic field in light of the press's incapacity to challenge the status quo and map the social world for its readers.

title: Indigenous languages shaping multi-lingual interfaces

authors: Keegan, Te Taka Adrian Gregory

subjects: computer science

abstract: This paper reports on an investigation into the indigenous language usage of two bilingual/multilingual digital libraries. Results show that the indigenous language was significantly used by clients and indicate why clients chose to use the indigenous language. Feedback from clients has suggested how the interface should be improved to assist both indigenous and non-indigenous language usage. These results serve as an example of how indigenous languages are shaping multilingual interfaces.
