Food for thought: the health of Pacific Islands young people in New Zealand : An Analysis Of The Dietary And Lifestyle Behaviours Of Pacific Islands Adolescents, And The Potential Long-Term Effects Of These Behaviours Upon Health

Hayes, Lisa Simone January 2001 (has links)
The aim of this thesis is to provide an overview of the health of Pacific Islands young people in New Zealand, with a particular emphasis on the effects of their dietary and lifestyle behaviours upon long-term health. This research is based on the observation that noncommunicable, or life-style, diseases are the leading causes of morbidity and mortality for Pacific Islands people in New Zealand, that these diseases are invariably attributable to dietary and lifestyle habits, and that these habits become instilled during the adolescent period. Three main methods were undertaken to achieve this aim. The first constituted a review of literature concerning the health of Pacific Islands people in New Zealand, including a discussion of what health means to Pacific Islands people, along with the main health issues that this population encounters. The importance of food to Pacific Islands people is also considered in this review, along with the influence of diet on Pacific Islands people's disease patterns. Existing studies concerning the dietary habits of Pacific Islands youth are also detailed. The second stage of the research involved conducting research into the health of Pacific Islands young people in Christchurch, based in part on the methodology and findings of these previous studies. As the thesis will show, while Christchurch has the fourth largest Pacific Islands population in New Zealand, this population is considerably smaller than those in other main centres. This means that Pacific Islands people have less health resources and services available to them. This research revealed that Pacific Islands young people in Christchurch, and in New Zealand in general, consume a diet that is high in fat and low in other nutrients. Research into the health of Pacific Islands young people is deemed necessary to help to counter the high incidence of lifestyle related diseases in the adult population. Further, by identifying potential health outlooks for the future generation of Pacific Islands adults, research in Christchurch will be useful in ensuring that services and resources to meet Pacific Islands people's specific health needs.

Sustainability of the Cayman Islands / Title from signature sheet: Sustainable development in the Cayman Islands

Kemper, Charles C. January 2005 (has links)
This study has presented a comprehensive overview of environmental and economic conditions in the Cayman Islands. The project studied the development patterns of the nation's largest island, Grand Caymans. The thesis determines the impact of development and project impacts of future development; the analysis portion clarifies the overall implications of rapid development. The latter half of the thesis, the solution portion, utilizes current theories, which are recommended by the Environment Protection Agency (EPA) such as Smart Growth and Green Development. The combination of the EPA's theories provides a compressive environmental plan that would ensure long-term environmental and economic sustainability. / Department of Landscape Architecture

Darwin and the island : the impact of evolutionary thought on certain island texts of Wells, Conrad and Golding

Fox, Justin Daniel January 1995 (has links)
This thesis examines the fictional island and assesses the impact of Darwinism on the genre. I show how islands have been a recurring feature in European literature, fictional spaces where authors create a microcosm in which they satirise, criticise or hold up a mirror to their own society. I argue that traditonal Utopian islands are static realms and that through the introduction of evolution (Darwin and Wallace made their most important discoveries regarding the mechanism of evolution on islands) fictional islands of the last century and a half have been radically transformed. The elements of chance, change, random mutation, natural and sexual selection, survival of the fittest as well as the knowledge of an animal heritage have changed the castaway experience, making it a far more anti-utopian one. The publication of The Origin of Species forced a reappraisal of all areas of knowledge and I show how, in the laboratory of the fictional island, authors examine the implications of Darwin's theory. Closely related issues are also taken into account, such as degeneration, the Second Law of Thermodynamics, developments in evolutionary anthropology, psychoanalysis and the coming of modern scientific method. I conduct a close reading of H. G. Wells' The Island of Doctor Moreau in which I consider the phenomenon of the mad scientist (in this case a modern, distinctly Darwinian scientist). Using some of Wells' scientific articles as a starting point, I show how the doctor tries to replicate a speeded up version of evolution in his island laboratory. Wells was a student of T. H. Huxley and the chapter examines the situation on the island in relation to Huxley's famous essay, "Evolution and Ethics", in which he argues that the "cosmic process" must be fought with an "ethical process". Wells called the novel a "theological grotesque" and I show how the novelist parodies orthodox Christianity and creates a protagonist who is a perverted evolutionary "god". Much of the remainder of the chapter is a detailed examination of degeneration in which I describe how the beast begins to resurface in Moreau's half-human creations as well as in the human protagonists (graphically evidenced in a "return" to cannibalism). A chapter on Joseph Conrad considers the pessimistic intellectual, philosophical and metaphysical forces that affect the novelist and his protagonist. First I show how the fin de siècle mood, in conjunction with the popular contemporary philosophies of Schopenhauer and Nietzsche (perceived in the light of Darwinian science) colour the cerebral landscape of Victory. The main thrust of this chapter concerns the issues of degeneration and devolution and in this respect I examine contemporary fears concerning cannibalism, thermodynamics, atavism and the anarchy resulting from a corrosion within society. I show further how the issue of sexuality (with relation to such issues as miscegenation, heredity and perversion) bears directly upon the idea of degeneracy. Finally the chapter considers the case of the imperial subject, the other "races" represented on Samburan. Here I am particularly interested in the anthropological application of Darwinism: far from being degenerate or inferior, Conrad depicts the racial other as having the "biological" advantage. By the time William Golding wrote Lord of the Flies, evolutionary elements were coming to novelists diluted in many different areas of enquiry. I discuss how Golding's knowledge of (evolutionary) anthropology and archaeology create a blueprint for the regression of English schoolboys to the level of "savages" and metaphorically to the level of early hominids and even animals. I show how the evil they try to externalise arises from within and is a part of their "animal" heritage. The chapter traces the path of their regression looking at aspects of their microcosmic society and religion. I also consider the situation of Golding's boys with relation to Freud's Totem and Taboo and his theories of child sexuality. Finally Golding's attempt to chart an existential and spiritual course through the waters of evolutionary determinism is discussed. In my concluding chapter I account for the "demise" of the Darwinian island showing how new issues are dominating the genre and in a close reading of Marianne Wiggins' John Dollar and J. M. Coetzee's Foe I examine how and why the postmodern and poststructuralist island fails to live up to the exigencies of the genre.

Strategic imperatives, British defence policy, and the case of the Falklands War 1982

Gibran, Daniel Kahlil January 1990 (has links)
This analysis proposes the thesis that in the formulation of post-war British defence policy, wider strategic developments taking place in the international environment are as important as, if not more than, domestic economic considerations, and examines the motivations that lay behind the British government's decision to recapture the Falkland Islands after their seizure by Argentine forces in April 1982. It is a first and comprehensive attempt to explore these two themes. It presents a challenge to the dominant view that British defence policy has, over the past two decades, been influenced by purely economic factors. Throughout the post-war era, defence analysts have come to accept the orthodox paradigm of British defence policy which attributes the reduction in the size of Britain's defence dispositions entirely to financial and economic pressures. While not negating the role of economic factors, this work rejects the gravamen of the orthodox paradigm and attempts to bring balance to the intellectual debate confronting British defence policy. Using the Falklands War as a case-study, this analysis demonstrates the salience of strategic imperatives and underscores the view that economic constraints can be pushed aside for what decision-makers perceive to be higher national and politico-strategic interests. It argues that while several factors may appear to have influenced the British decision to retake the Islands, only two interlocking sets are truly credible. These relate to national honour considerations and the fight for principles. Moreover, it argues that the credibility of the latter flows from the primacy of pride and prestige, thus making national honour considerations the dominant motif or explanation. The analysis begins with a review of the literature and shows the gaps which this work attempts to fill. Chapter Two examines the strategic and economic trends and developments in British defence policy prior to the Falklands War. Chapter Three presents a comprehensive picture and explanation of the Falkland Islands as an issue of long-standing dispute between Argentina and Britain. In Chapter Four, the factors that prompted the Junta to launch its attack are examined and the British response discussed. Chapters Five and Six utilize the Falklands War as a formidable case to support the major theme of this work. Chapter Seven provides a summary, and concludes with a short examination of four basic issues relating to the analysis.

Magnetic profiles across the Aleutian Trench and ridge

Skorpen, Allan Jerome 09 October 1967 (has links)
During the North Pacific cruise of the R/V Yaquina in 1966, total magnetic field intensity was measured in the Andreanof group of the Aleutian Islands. Three north-south track lines were made across the Aleutian Trench and ridge between longitudes 175° W and 180°. Three small scale magnetic profiles across the trench and ridge and one large scale profile over the crest of the ridge were constructed from the data. Total field and anomaly contour maps were drawn from the profiles. The data reveal: 1. A strong east-west trend of the contours present south of the ridge but absent north of the ridge which suggests that the Aleutian ridge is the boundary of two different magnetic provinces. 2. Large anomalies south of the trench which appear to be continuous for a distance of about 500 miles. The anomalies result from shallow structures and are considered to be ocean floor magnetic lineations. 3. Large anomalies north of the trench which result from deep-seated structures, probably strongly magnetic intrusions. 4. Short wavelength anomalies on the crest of the ridge which may result from dike intrusions parallel to the trend of the ridge. 5. A local magnetic gradient of about 800 gammas after removal of the regional geomagnetic field. The residual gradient is "low" over the trench and "high" over the ridge. The magnetic variation may be related to changes in the depth of the Curie temperature isotherm. / Graduation date: 1968

Development of a Species Distribution Model for the East Pacific Green Sea Turtle using Ecological Geoprocessing Tools

Duncan, Roxanne 2012 August 1900 (has links)
East Pacific green sea turtles, Chelonia mydas, play ecologically important roles in marine habitats which range from grazing (and thus regularly "mowing") algae and seagrass beds to cycling nutrients between the ocean and land. However, these important grazers have been hunted to ecological extinction in some places for their eggs, meat, and skin. The conservation initiative for the survival of sea turtles requires the protection of their primary habitats in conjunction with a decrease in their interaction with humans. One way these objectives can be met is through the creation of species distribution maps (SDMs). For this thesis, a SDM was created from a generalized additive model used to identify major feeding areas for East Pacific green turtles residing in the Galapagos Islands. The input for the model was green turtle sighting locations during a June 2010 marine life observation survey and remotely sensed values of four oceanographic parameters obtained from satellite sensors (Bathymetry, Sea Surface Temperature, Chlorophyll a, and Current Speed). Line transects of intertidal and subtidal shoreline regions of the islands of Isabela, San Cristobal, and Floreana were also completed, to describe similarities and differences in macroalgal abundance between the locations. A generalized additive model (GAM) explained 56% of the data's null deviance and had a true positive rate of 0.83. The corresponding species distribution map indicated that East Pacific green sea turtles prefer to forage in warm, low chlorophyll a, slow moving waters at depths mostly less than 250m throughout the archipelago. ANOVA analyses showed that macroalgal abundance was statistically different (p-value < 0.01) between the islands of San Cristobal and Isabela. The line transects analysis also documented that red algae was the most prominent phyla at the sites and that the macroalgal abundance did not vary much between months June 2010 and April/May 2011. With these results, potential foraging areas for East Pacific green turtles can be identified and protected. Future studies will be focused on the collection of macroalgae from coastal areas outlined in the SDM and the interactions between green turtles and their competitors and/or predators. This information can be used to validate the areas delineated by the model and to further the understanding of the spatial-temporal effects on macroalgal abundance.

Interactions Between Sea Water and Coral Reefs in Kaneohe Bay, Oahu, Hawaii

Klim, Donald G 01 June 1969 (has links)
TIlis study, covering a period of eight months, was undertaken to determine if measurable changes in characteristics occur in sea water passing over a shallow coral reef. The parameters studied include salinity, temperature, current velocities, dissolved oxygen, pH, dissolved organic carbon and particulate organic and suspended inorganic carbon. Staining and microscopic observations were made to supplement the other data. The results showed noticeable increases in oxygen, pH, particulate organic and inorganic carbon abundance in the central portion of the reef, which were attributed to the influence of extensive growths of benthic algae found on the seaward edge. Dissolved organic carbon concentration increased gradually across the reef, and there is evidence that inorganic carbonate is being accumulated on the leeward side of the reef. / Typescript.

A future in the past : urban agroforestry systems in future planned urban settlements in Kiribati, a Pacific case study

East, Andrew John January 2008 (has links)
In the last 50 years, Pacific Island Countries (PICs) have experienced unprecedented levels of urban development. During this time, the general failure of traditional industrialised planning models to be successfully adapted in PICs has resulted in the need to explore alternative models for urban settlement in the Pacific. In this way, the incorporation of tree based agricultural systems (agroforestry) into urban settlements has considerable potential to address many of the problems associated with rapid urbanisation such as food security, waste management, environmental degradation and unemployment. Research in the Pacific has already shown how urban agroforestry systems can improve food security, increase access to nutritional foods, recycle organic waste, create employment and protect fragile ecological systems. However, in Pacific towns and cities urban agroforestry systems are rarely developed beyond a homegarden setting. The growth of urban centres in the Republic of Kiribati is an example of the challenges confronting many rapidly urbanising PICs. With infertile soils, severely restricted land and water resources and an emerging economy, Kiribati is a developing nation where sustainable development faces some of its greatest challenges. Due to rapidly expanding urban populations, the Kiribati Government is currently investigating the development of future planned urban settlements. In such a scenario, potential exists to extend urban agroforestry systems beyond a homegarden setting and explore alternative models for sustainable urbanisation in the Pacific. This research uses a mixed methods case study approach to investigate the potential role of food producing urban agroforestry systems in future planned urban settlements in Kiribati. More specifically, qualitative procedures are used to explore issues surrounding the promotion and development of urban agroforestry systems in future planned urban settlements while quantitative procedures are used to analyse the nutritional contribution of these systems. Findings from this study show that although urban agroforestry is a highly sustainable land use it faces two main challenges in Kiribati: (i) people’s perception that urban agroforestry systems are a relatively low value land use and (ii) the general inability of the Kiribati Government to effectively regulate urban land uses. However, in the event that urban agroforestry systems were deliberately included at a settlement wide scale beyond a homegarden setting, this study highlights the initial importance of equally allocating productive lands to individual households. Furthermore, the results emphasise the value of simple on-site composting technologies as components of the broader urban agroforestry system. Finally, the marginal nature of the atoll environment is evident in findings on the nutritional contribution of urban agroforestry species in future planned urban settlements. In summary, while considerable constraints must be overcome to ensure the long term viability of planned urban agroforestry systems at a whole of settlement scale, it is argued that such an approach is one of the most cost effective, culturally acceptable and environmentally responsible methods for addressing a range of urban issues in the Pacific and is therefore an essential component to the design of future planned urban settlements in Kiribati.

"Te Tahi o Pipiri" : Literacy and missionary pedagogy as mechanisms in change. The reactions of three rangatira from the Bay of Islands: 1814-1834

Tuato'o, Danny, n/a January 1999 (has links)
This thesis is concerned with the ways Imperialism (and consequently colonialism) has pervaded the indigenous �primitive� world. Protectorates and �the colonies� reflected imperialist ideals, expansion, territory, external revenue and power. Missionaries were the footmen of colonial policy. The relations forged between these evangelists and the indigene have been thoroughly studied and scrutinised. However, reported interaction has been about missionaries and the �native�, with less about that between the indigenes, individual and tribe, elder and young. The thesis intends to redress this imbalance in the Bay of Islands from 1814 to 1834. The following work is an examination of a process of social change in Aotearoa. In the early 19th century the physical, spiritual and intellectual contact made between Maori peoples and the European explorers, scientists, and missionaries involved a deliberate cultural entanglement. It is the processes of acculturation, assimilation, or simply misunderstanding that are of interest. The study will have several foci involving the reaction of peoples of the Bay of Islands to the missionary institution of religious education. Chapter One addresses the theoretical location of the peoples that interacted in the Bay, while the second chapter is a brief description of a Maori coastal society prior to the arrival of literate missionaries. Chapter Three is about the cultural and social engagements of Ruatara, Marsden, Kendall and Hongi. The final chapter is a biographical exploration in the life of Rawiri Tawhanga and his interactions with missionaries and Maori of the Bay. Fundamentally it is the indigenous interaction during the initial periods of external European contact and, therefore, the effects of internal societal change that the author wishes to examine.
