Latexy modifikované cementové materiály / Latexes modified cementitious materialsVinter, Václav January 2008 (has links)
In this thesis, the development of mechanical properties and structure of latex modified cementious materials during hydration was studied. Latex modified materials are composites of inorganic cement (portland cement) and organic polymer latex. Preparation, processing and fabrication of the polymer cement material based on portland cement was optimized with aim to reach the most compact structure of the product with the finest mechanical characters. The experimental part was pointed to observe influence of the type and amount of polymer latex with focus on mechanical characters and hydration kinetics with given filling as well as without it. In presented work, the possibility of compaction of the material by high-shear mixing within twin-roll mixer (the prototype for production of MDF composite) was verified. The second part of the labor was aimed to analysis of prepared polymer-cementitious material. For determination of influence of batching of added polymer latex on hydration of cement paste the thermal analysis (DTA/TGA) and infrared spectroscopy of composite was done. At last the microscopic observation by optical microscope was carried.

For better or for worse ... : a case study analysis of social services partnerships in Aotearoa/New ZealandWalker, Peter E, n/a January 2007 (has links)
Partnerships between organizations are seen as one of the building blocks of the �Third Way� approach to welfare provision both in Europe and in New Zealand. While there is much discussion of this emphasis on building social capital and working in partnerships these partnerships are usually perceived as being between government and community or private organizations as part of a new phase of neo-liberalism. Using qualitative research this thesis explores three partnership sites: Those within a Maori social service provider, Te Whanau Arohanui, and the local Hapu and State organisations; that between the Ngai Tahu Maori Law Centre (an indigenous organization) and the Dunedin Community Law Centre; and finally the State lead Strengthening Families partnership initiative.
This thesis is concerned with the development of citizen participation in public policy decision-making through partnerships. While contemporary studies of policy change have identified stakeholder and actor-network forms as dominant these often seem even less democratic, participatory, accountable and transparent than those they have supposedly replaced. I draw on ideas of deliberative governance to explore options for both the theory and practice of sustainable, permanent and participatory policy change in an age of diversity. I suggest that the practice of Community Development is needed to supplement descriptive and post-facto accounts of policy change and so create a usable practice theory of effective mechanisms for participatory input.
Using a series of case studies of partnerships, a tentative practice theory and strategy for change is proposed. This is set within an interactive framework that is able to confront levels of power to encourage diversity and participation in decision-making from bottom-up initiatives.

A history of Christchurch home gardening from colonisation to the Queen's visit: gardening culture in a particular society and environmentMorris, Matt January 2006 (has links)
Garden histories since the mid 1990s have increasingly turned to studies of vernacular gardens as sites of identity formation. More recently, the development of environmental history and specifically urban environmental history has started to show how vernacular gardening in suburban and urban spaces has contributed to changes in urban environments. Relatively little work on home gardening history in this sense has been undertaken in the New Zealand context, while in Australia such work is well underway. This study augments knowledge of home gardening history in New Zealand by focussing on one urban area, Christchurch, known both as the 'Garden City' and as 'one of the most English cities outside of England'. An examination of gardening literature over the period from European colonisation in 1850 to the first visit to the city by a reigning monarch in 1954 highlights changes in gardening tropes rather than particular garden fashions or elements. The four principal tropes of abundance, beauty, protection and sustenance, each supported with a particular kind of ritual-like garden competition, show how gardening discourses related to ideas about the maintenance of the social and cultural order. A more objective measure of attitudes to gardens is gained by examining 1823 property advertisements across the period. Categorised by suburb this analysis shows a level of gardening variation across the city. Following this analysis, case studies of four suburbs in three areas were undertaken. These were based primarily on oral histories and reveal the extent of gardening variation across the city, and the limited but significant effect that gardening discourses had on gardens. This suggests methodological problems with many studies of vernacular gardens, as well as opportunities for further studies. This thesis also demonstrates the value of home gardening histories to urban environmental history, particularly with regard to the former colonies of the British Empire.

He Atua, He Tipua, He Takata Rānei: The Dynamics of Change in South Island Māori Oral TraditionsPrendergast-Tarena, Eruera Tarena January 2008 (has links)
The aim of this thesis is to undertake a theoretical analysis of the dynamics of change in pre-Ngāi Tahu and Ngāti Māmoe oral traditions of Te Waipounamu to gain a deeper understanding of their nature, function, evolution and meaning. For the purposes of this thesis a framework will be established to classify changes to encompass different types of alterations made pre-contact and post-contact to authentic and un-authentic oral traditions. This model will analyse the continuum of change and will be applied in later chapters to pre-Ngāi Tahu and Ngāti Māmoe traditions to gain an understanding of the dynamics, evolution and construction of the oral traditions of Te Waipounamu. This study of the morphology of tradition will demonstrate they were never fixed but evolved alongside their communities as they adapted to ensure tribal identity and mana was firmly entrenched in their local landscape.
A major component of this thesis will be analysis of Waitaha traditions centring upon three key questions; firstly who were Waitaha peoples, secondly, where were they from, and thirdly, were they, and do they continue to be separate social units? This thesis will contribute to this discussion by analysing literature concerning pre-Ngāi Tahu and Ngāti Māmoe tribal identities to ascertain not just who they were and where they were from but how their identities have been constructed and modified over time. Analysis will examine the role of oral tradition in establishing tribal identity and how Waitaha traditions were changed both pre and post-contact to suit the cultural, political and ideological imperatives of the time, providing an insight into how our ancestors perceived, recollected and constructed the past to suit the needs of the present.

Analýza deformace dřeva s imperfekcí na základě srovnání jednoduchého numerického modelu s optickou metodou DICKlvač, Ondřej January 2016 (has links)
This work is devoted to the analysis of wood with imperfection in tension, digital image correlation method and finite element method. It is investigated the comparability of the results of these two methods on the example of behaving of the wood in tension with imperfection. The imperfection could be for example any weakening of the wood structure. It could be natural (knots, cracks and so on). The example of artificial imperfection here is a drilled hole. In this work an experiment with plastic sample in the same manner was also conducted in order to validate the analytical procedure for calculating the stress and practically demonstrate the difference between isotropic and anisotropic material. The work also includes general information from the literature, theoretical assumptions, methodologies, measured results and the comparison of these results each other and with the literature. The result of this work is to evaluate the behavior of wood with a hole in the tension and the comparison of these two methods of measuring deformation. In the end there are the advantages and disadvantages of each method.

Sharing the land: the formation of the Vancouver Island (or 'Douglas') Treaties of 1850-1854 in historical, legal and comparative contextVallance, Neil 18 March 2016 (has links)
Chapter I introduces the Vancouver Island or ‘Douglas’ Treaties of 1850-54, entered into between several Vancouver Island First Nations and Hudson’s Bay Company Chief Factor, James Douglas, acting as agent of the Crown. The written versions purported to extinguish the aboriginal title of the First Nations to their land. Recent research has indicated that these documents do not accurately reflect what was agreed between the parties at the treaty meetings. The goal of the dissertation is to ascertain the likely terms of the treaties. This task also posed my major research challenge, as very little contemporaneous documentation exists of the formation of the treaties. There are a number of first- and second-hand accounts reduced to writing long after the events described, but they have received little attention from scholars until now. Chapter II is devoted to a critical analysis and comparison of the extant First Nation and colonial accounts, from which I conclude that the treaties were likely agreements by the First Nations to share not cede their land. Chapter III makes a comparison with first person accounts of the Washington or ‘Stevens’ Treaties of 1854-55, entered into between
vii
viii Native American tribes and the United States government. I conclude that these accounts
bolster the likelihood that the Vancouver Island agreements were sharing treaties. Chapter IV follows up on a fascinating connection between the written versions of the Vancouver Island Treaties and an agreement concerning land between the Ngai Tahu Moari of New Zealand’s south island and Henry Kemp, acting as agent of the Crown. The comparison provides a number of useful contrasts and parallels with the Vancouver Island Treaties. Chapter V describes the silencing of the Vancouver Island Treaties by the policies of successive governments, the inattention of scholars and the decisions of Canadian courts. Finally, Chapter VI reviews existing and potential categories of historical treaties between First Nations and the Crown. By analogy with treaty categories in international law and the work of political and legal theorists, I make the case for the Vancouver Island Treaties as examples of modus vivendi (interim or framework agreements). / Graduate / 2017-02-24
