title: Diverse and highly active diazotrophic assemblages inhabit ephemerally wetted soils of the Antarctic Dry Valleys

authors: Niederberger, Thomas D.

subjects: diazotrophs

abstract: Eolian transport of biomass from ephemerally wetted soils, associated with summer glacial meltwater runoffs and lake edges, to low-productivity areas of the Antarctic Dry Valleys (DV) has been postulated to be an important source of organic matter (fixed nitrogen and fixed carbon) to the entire DV ecosystem. However, descriptions and identification of the microbial members responsible for N₂ fixation within these wetted sites are limited. In this study, N₂ fixers from wetted soils were identified by direct nifH gene sequencing and their in situ N₂ fixation activities documented via acetylene reduction and RNA-based quantitative PCR assays. Shannon-index nifH diversity levels ranged between 1.8 and 2.6 and included the expected cyanobacterial signatures and a large number of phylotypes related to the gamma-, beta-, alpha-, and delta-proteobacteria. N₂ fixation rates ranged between approximately 0.5 and 6 nmol N cm⁻³ h⁻¹ with measurements indicating that approximately 50% of this activity was linked with sulfate reduction at some sites. Comparisons with proximal dry soils also suggested that these communities are not ubiquitously distributed, and conditions unrelated to moisture content may define the composition, diversity, or habitat suitability of the microbial communities within wetted soils of the DVs.

title: An Elusive Dream: Multiracial Harmony in Fiji 1970-2000.

authors: Gaunder, Padmini

subjects: Fiji

abstract: The common perception of Fiji, which is unique in the South Pacific, is that of an ethnically divided society with the indigenous and immigrant communities often at loggerheads. This perception was heightened by the military coups of 1987, which overthrew the democratically elected government of Dr. Timoci Bavadra because it was perceived as Indian-dominated. Again in 2000, the People's Coalition Government headed by an Indian, Mahendra Chaudhry, was ousted in a civilian coup.

Yet Fiji had been genuinely multiethnic for several decades (even centuries) before it became a colony in 1874. From then onwards, however, because of the policies of the colonial government, the society slowly became plural (in Furnivall's classic sense) as the different races were separated in almost every walk of life. Until the 1920s there were hardly any conflicts between Fijians and Indians.  From the 1920s, however, the Fijians were taught to be wary of the Indians.

After independence in 1970, the Alliance government under Ratu Sir Kamisese Mara followed a policy of  multiracialism  with the stated aim of bringing the different ethnic groups together in a society where people achieved some degree of integration in terms of a common national identity, while retaining their own separate traditions.  But, more than thirty years later, Fiji still remains an ethnically divided society with hardly any integration. My research explores the reason for this failure.

My thesis is that the failure arose from the kind of democratic system that the country adopted at independence. That is, the Westminster concept of government and opposition can be problematic in a multiethnic society if political parties are divided on ethnic lines rather than based on political ideologies. Ratu Mara was one Fiji leader who recognized this problem and had said that the confrontational Westminster system is not appropriate in a South Pacific island with a multiracial population.

While Stephanie Lawson, Peter Larmour, Futa Helu and others have made some important contribution to this debate, my thesis will focus on an argument put forward by  Michael Goldsmith on the role of the opposition, making a distinction between two kinds of pposition,  confrontational  and  thoughtful . This thesis contends that the Westminster system that Fiji adopted at independence failed to bring integration in part because the National Federation Party (NFP) degenerated over the years from a 'thoughtful' and effective opposition to a 'confrontational', ethnic opposition.

title: Māori whānau experiences of a neonatal intensive care unit: Waikato hospital

authors: Thompson, Keri

subjects: Maori whanau narratives

abstract: This thesis topic emerged from my personal experience of having a premature baby in the Neonatal Intensive Care Unit (NICU) at Waikato hospital.  My whānau and I felt like aliens; culturally inept, and totally alone during our time in the NICU.  It was not until I spoke to other Māori mothers that I realised our stories were similar.   

I sought to understand how other Māori whānau members made sense of their own experiences, how they coped/adjusted to the experience of having a premature baby in an NICU and at home, and the sources of support they utilised. This study did not seek to delineate parents' experiences but attempted to allow whānau members to share their stories and explore their experiences of having a premature or special-care baby in an NICU.

The event of childbirth and the placing of a natural event into a pathological illness model through necessity has repercussions for the ways in which women experience and make sense of the event.  Knowing this, six whānau stories were collected comprising of four individual interviews with the mothers and two whānau hui (focus groups).  My use of a narrative methodology and kaupapa Māori approach enabled all the participants the opportunity to share their stories on how they make sense of their own experiences without the frame of pathological illness. 

The findings present each whānau story autonomously, to highlight the key events that   occur once the birth of a premature/special-care infant is admitted into an NICU. The participants' narratives followed their transitions through an NICU and return home. The narrative analysis and discussion confirmed that this research had been successful in creating a space for the mothers and their whānau members to share their stories.  The discussion combined their narratives to reveal that the effective coping strategies did not remove the sources of stress but rather lessened the impact of the stresses.  In situations where sources of stress were unable to be removed or reduced, participants perceptions of ineffective coping translated into narratives of negative perceptions of the NICU, and birthing experience. 

The importance of positive relationships within an NICU, and in particular, the role of the nurse as a key facilitator, highlighted that efficacious communication resulted in positive experiences for Māori whānau.  Whānau support was identified as one of the most important coping strategies for mothers in the NICU.  Those participants who were encouraged to maintain connections with whānau members reported more positive experiences overall.

Three levels of implications were identified in this research. Firstly, that the participants'narratives provided a range of coping strategies for future Māori parents and their whānau who enter an NICU.  Secondly, there are implications for NICU policy, and best practice particularly when supporting Māori in an NICU environment.  Lastly, the narratives provided meaningful insights that contribute to gaps in local, national, and international literature.  Overall, I realised that just like me, these mothers, and other whānau members, constructed narratives that are meaningful accounts to be shared with others.
