Peacebuilding Theory in the Pacific Context: Towards creating a categorical framework for comparative post-conflict analysis

Adams, Nicholas Marc January 2008 (has links)
The transformation period between intrastate civil conflicts has been primarily examined within sporadic case studies. A lack of macro theory in the field of Peacebuilding has led to a predisposition towards policy-friendly academic works. The policy changes and studies that get suggested take advantage of hindsight and are often case specific. Without allowing for the variances in differing post-conflict situations the changes struggle to provide usable theoretical works. This field requires accurate comparative studies, but the dominance of micro theoretical casework has undermined any larger analysis. This thesis proposes a categorical framework for qualitative analysis of post-conflict studies and tests it within a series of conflicts in the Pacific region. Comparing the Bougainville independence conflict, Fijian coups and reoccurring violence in the Solomon Islands, the differences apparent in each case will demonstrate what changes occur for better or worse, reinforcing the need for more incorporative frameworks.

ANZAC Peacekeeping: Trans-Tasman Responses to the Bougainville Crisis in 1997 and the Subsequent Evolution of Australia's and New Zealand's Regional Peacekeeping

Baird, Rosemary Anne January 2008 (has links)
This thesis investigates the evolution of Australian and New Zealand peacekeeping operations in the Pacific through a trans-Tasman lens. Both Australian and New Zealand sources are used in order to understand the relationship and interaction between the two nations. This study has a particular focus on the Truce Monitoring Group (TMG) sent to Bougainville in late 1997. This New Zealand-led operation was the first long-term regional peace initiative of recent times, and set the stage for future regional interventions by Australia and New Zealand. The thesis also considers more broadly the subsequent involvement of Australian and New Zealand peacekeepers in the International Force in East Timor (INTERFET) and Regional Assisted Mission to Solomon Islands (RAMSI). These two later operations are considered with particular attention to lessons learnt from previous peacekeeping experiences and the changing tenor of trans-Tasman relations. Since this is a history thesis it sets the argument within a historical and historiographical framework. It seeks to identify long-term trends surrounding Australia's and New Zealand's relationship with the Pacific, defence connection and Anzac heritage. A further aim of this thesis is to investigate whether joint Australian and New Zealand peacekeeping in the Pacific revived the Anzac relationship first formed at Gallipoli. By looking at evidence taken from interviews and first-hand accounts with Australian and New Zealand participants in the TMG, INTERFET and RAMSI, this thesis argues that hallmarks of the earlier Anzac relationship did re-emerge, though in a slightly different form. The phenomenon of New Zealand's reputation as having a cultural advantage in the Pacific is explored in some detail as this is an important aspect of the Anzac relationship.

The hybrid list decoding and Chase-like algorithm of Reed-Solomon codes.

Jin, Wei. January 2005 (has links)
Reed-Solomon (RS) codes are powerful error-correcting codes that can be found in a wide variety of digital communications and digital data-storage systems. Classical hard decoder of RS code can correct t = (dmin -1) /2 errors where dmin = (n - k+ 1) is the minimum distance of the codeword, n is the length of codeword and k is the dimension of codeword. Maximum likelihood decoding (MLD) performs better than the classical decoding and therefore how to approach the performance of the MLD with less complexity is a subject which has been researched extensively. Applying the bit reliability obtained from channel to the conventional decoding algorithm is always an efficient technique to approach the performance of MLD, although the exponential increase of complexity is always concomitant. It is definite that more enhancement of performance can be achieved if we apply the bit reliability to enhanced algebraic decoding algorithm that is more powerful than conventional decoding algorithm. In 1997 Madhu Sudan, building on previous work of Welch-Berlekamp, and others, discovered a polynomial-time algorithm for decoding low-rate Reed- Solomon codes beyond the classical error-correcting bound t = (dmin -1) /2. Two years later Guruswami and Sudan published a significantly improved version of Sudan's algorithm (GS), but these papers did not focus on devising practical implementation. The other authors, Kotter, Roth and Ruckenstein, were able to find realizations for the key steps in the GS algorithm, thus making the GS algorithm a practical instrument in transmission systems. The Gross list algorithm, which is a simplified one with less decoding complexity realized by a reencoding scheme, is also taken into account in this dissertation. The fundamental idea of the GS algorithm is to take advantage of an interpolation step to get an interpolation polynomial produced by support symbols, received symbols and their corresponding multiplicities. After that the GS algorithm implements a factorization step to find the roots of the interpolation polynomial. After comparing the reliability of these codewords which are from the output of factorization, the GS algorithm outputs the most likely one. The support set, received set and multiplicity set are created by Koetter Vardy (KV) front end algorithm. In the GS list decoding algorithm, the number of errors that can be corrected increases to tcs = n - 1 - lJ (k - 1) n J. It is easy to show that the GS list decoding algorithm is capable of correcting more errors than a conventional decoding algorithm. In this dissertation, we present two hybrid list decoding and Chase-like algorithms. We apply the Chase algorithms to the KV soft-decision front end. Consequently, we are able to provide a more reliable input to the KV list algorithm. In the application of Chase-like algorithm, we take two conditions into consideration, so that the floor cannot occur and more coding gains are possible. With an increase of the bits that are chosen by the Chase algorithm, the complexity of the hybrid algorithm increases exponentially. To solve this problem an adaptive algorithm is applied to the hybrid algorithm based on the fact that as signal-to-noise ratio (SNR) increases the received bits are more reliable, and not every received sequence needs to create the fixed number of test error patterns by the Chase algorithm. We set a threshold according to the given SNR and utilize it to finally decide which unreliable bits are picked up by Chase algorithm. However, the performance of the adaptive hybrid algorithm at high SNRs decreases as the complexity decreases. It means that the adaptive algorithm is not a sufficient mechanism for eliminating the redundant test error patterns. The performance of the adaptive hybrid algorithm at high SNRs motivates us to find out another way to reduce the complexity without loss of performance. We would consider the two following problems before dealing with the problem on hand. One problem is: can we find a terminative condition to decide which generated candidate codeword is the most likely codeword for received sequence before all candidates of received set are tested? Another one is: can we eliminate the test error patterns that cannot create more likely codewords than the generated codewords? In our final algorithm, an optimality lemma coming from the Kaneko algorithm is applied to solve the first problem and the second problem is solved by a ruling out scheme for the reduced list decoding algorithm. The Gross list algorithm is also applied in our final hybrid algorithm. After the two problems have been solved, the final hybrid algorithm has performance comparable with the hybrid algorithm combined the KV list decoding algorithm and the Chase algorithm but much less complexity at high SNRs. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, 2005

Choiseul and the missionaries : the Methodist Mission on Choiseul, Solomon Islands, 1905-1941 : a thesis submitted for the degree of Master of Philosophy at Massey University, Albany

McDonald, Lynne January 2009 (has links)
This project will examine the impact and the progress of Methodist missionary work on Choiseul from 1905 to 1941. The predominant European contact on Choiseul was with missionaries and this was significantly more recent than many of the other islands in the group. Choiseul was unattractive for settlement or commercial development because the lack of arable land meant that it was unsuitable for large plantations to be established. A lacuna exists in the current historiography of the Solomons with regard to Choiseul. A study of the Methodist Mission on Choiseul offers the opportunity to examine the development of the mission, and the people on the island during the period under study, and fill that gap. The nature of conversion to Christianity on Choiseul, and the way the missionaries, including European, Solomon Islanders and Pacific Islanders, operated, cooperated, and disagreed with the Choiseulese and with each other will be examined to help answer the question, to what extent was Choiseul a Methodist, or a missionary, island.

The role of Customary Marine Tenure and local knowledge in fishery management at West Nggela, Solomon Islands

Foale, Simon Unknown Date (has links) (PDF)
A proper understanding of the management of small-scale subsistence and artisanal fisheries requires not only detailed sociocultural study, but comprehensive analysis of the state of the fished population(s) using rigorous stock assessment and other fisheries biology tools. This study comprises such an interdisciplinary approach taken in an attempt to understand subsistence and artisanal fishing at West Nggela, with a particular focus on the management of the artisanal trochus fishery. The importance of an understanding of Customary Marine Tenure is dealt with in some detail. An analysis of the various categories of fishers’ ecological knowledge about marine fauna, with an emphasis on trochus, is also presented, and discussed with respect to the categories of biological and ecological information considered by most fisheries biologists as essential to the assessment and management of a fishery. The theoretical basis of my approach to the study of local knowledge, which could broadly be termed “rationalist”, is discussed and defended against “postmodernist” criticisms.
