This chapter discusses national literary histories in Australia, Canada, New Zealand, and the South Pacific and summarises the book's main findings regarding the construction and revision of narratives of national identity since 1950. In colonial and postcolonial cultures, literary history is often based on a paradox that says much about their evolving sense of collective identity, but perhaps even more about the strains within it. The chapter considers the complications typical of postcolonial literary history by focusing on the conflict between collective celebration and its refutation. It examines three issues relating to the histories of English-language fiction in Australia, Canada, New Zealand, and the South Pacific: problems of chronology and beginnings, with a special emphasis on Indigenous peoples; the role of the cultural elite and the history wars in the Australian context; and the influence of postcolonial networks on historical methodology.

<p>Subantarctic New Zealand is an oceanographycally dynamic region with the Subtropical Front (STF) to the north and the Subantarctic Front (SAF) to the south. This thesis investigates the ocean structure of the Campbell Plateau and the surrounding New Zealand subantarctic, including the spatial, seasonal, interannual and longer term variability over the ocean properties, and their connection to atmospheric variability using a combination of in-situ oceanographic measurements and remote sensing data.  The spatial and seasonal oceanographic structure in the New Zealand subantarctic region was investigated by analysing ten high resolution Conductivity Temperature and Depth (CTD) datasets, sampled during oceanographic cruises from May 1998 to February 2013. Position of fronts, water mass structure and changes over the seasons show a complex structure around the Campbell Plateau combining the influence of subtropical and subantarctic waters.  The spatial and interannual variability on the Campbell Plateau was described by analysing approximately 70 low resolution CTD profiles collected each year in December between 2002 and 2009. Conservative temperature and absolute salinity profiles reveal high variability in the upper 200m of the water column and a homogeneous water column from 200 to 600m depth. Temperature variability of about 0.7 °C, on occasions between consecutive years, is observed down to 900m depth. The presence of Subantarctic Mode Water (SAMW) on the Campbell Plateau is confirmed and Antarctic Intermediate Water (AAIW) reported for the first time in the deeper regions around the edges of the plateau.  Long-term trends and variability over the Campbell Plateau were investigated by analysing satellite derived Sea Level Anomalies (SLA) and Sea Surface Temperature (SST) time series. Links to large scale atmospheric processes are also explored through correlation with the Southern Oscillation Index (SOI) and Southern Annular Mode (SAM). SST shows a strong seasonality and interannual variability which is linked to local winds, but no significant trend is found. The SLA over the Campbell Plateau has increased at a rate of 5.2 cm decade⁻¹ in the last two decades. The strong positive trend in SLA appears to be a combination of the response of the ocean to wind stress curl (Ekman pumping), thermal expansion and ocean mass redistribution via advection amongst others.  These results suggest that the variability on the Campbell Plateau is influenced by the interaction of the STF and the SAF. The STF influence reaches the limit of the SAF over the western Campbell Plateau and the SAF influence extends all around the plateau. Results also suggest different connections between the plateau with the surrounding oceans, e.g., along the northern edge with the Bounty Trough and via the southwest edge with the SAF. A significant correlation with SOI and little correlation with SAM suggest a stronger response to tropically driven processes in the long-term variability on the Campbell Plateau.  The results of this thesis provide a new definitive assessment of the circulation, water masses and variability of the Campbell Plateau on mean, annual, and interannual time scales which will support research in other disciplines such as palaeoceanography, fisheries management and climate.</p>

All governments face difficulties in trying to ensure the full participation of every citizen. The further a citizen is located from the centre of power and administration, such as a capital city, the less engaged they are likely to be. This phenomenon can be observed at both a national and an international level. At the global level countries located in close proximity to major world markets are more likely to have well-developed e-government services, than more marginally located countries, particularly those with low population densities. Within individual countries, there is typically a marked variation between rural and urban areas both in terms of access to available infrastructure and uptake by citizens (Parker, 2000). In general, the more remote the location and the smaller the population density, the lower the rate of participation will be. This can be observed in even in the most highly developed, highly populated countries; for example, the Japanese government struggles to provide the often elderly residents of remote islands with government services (Hayashi & Hori, 2002). In a country that is less developed without easy access to major world markets, the effects on rural citizens are intensified. The small island developing states of the South Pacific are some of the most remotely located nations in the world; their economies are relatively underdeveloped and they have low population densities. By researching the difficulties faced in attempting to implement e-government in some of the most distant corners of the earth, lessons can be learned about the way that information and communication technologies (ICTs) can overcome the barriers of geography. The insights gained from this exercise are relevant worldwide; as many economically developed countries also have pockets of population that are hard to reach. A counter argument is that some of these differences may be attributable to a country’s level of economic development rather than it’s actual geographic location. A notable example of a remotely located country that has a highly developed e-government system is New Zealand. Despite having only four million inhabitants, and being placed on the other side of the globe from the major world markets of Europe and the USA, in 2001 New Zealand was nominated by the UN as the country with the third most advanced e-government system in the world (Boyle & Nicholson, 2003). ICTs now make it possible to connect a citizen in even the most far-flung location directly to central government services. This article investigates the status of e-government in remote locations. Representatives from ten different South Pacific Islands were surveyed to discover what they perceived as the main barriers and opportunities in developing e-government in each of their different countries. The island states of the South Pacific have developed independently and are culturally diverse. However, they all share some common features with regards to adoption of ICTs. In order to appreciate these factors more fully, one country, Samoa, has been used as an example. By comparing Samoa with New Zealand, lessons can be learned about how to utilise ICT to overcome the disadvantages of distance and low population. E-government is sometimes viewed as a subset of e-commerce. However, it needs to be remembered that there are substantive differences between the private and public sectors. Governments have a duty to make sure that services are available to all citizens, and usually the citizens who are the most needy are those who have the least access to government services (Curthoys & Crabtree, 2003). Often this is because such citizens live in remote rural locations. The public sector is a law-based system, and government includes many processes that are different from processes encountered in private sector settings such as retail or banking, for example: complex decision making; negotiations between stakeholders; policy formulation; and democratic participation (Lenk, 2002). An example is the highly contentious issue of land ownership in the South Pacific; the use of e-government could potentially help land boards to demonstrate a fair and transparent approach to this issue.
