Trends in forestry mechanization and concepts for containerized seeding in New Zealand

Page, Arthur Ian January 1971 (has links)
Review of the literature on the future of wood resulted in the conclusion that long term future demand will be for large quantities of cheap fibre. There is likely to be a reduction in emphasis on the form and dimension of individual trees. Mechanization and automation are defined and the relative importance of tree establishment within the total forest industry noted. Some general principles of forest mechanization are proposed and discussed. The New Zealand potentials for wood fibre production and forest mechanization are analysed. Reforestation history of radiata pine (Pinus radiata, D.Don.) in New Zealand is briefly described, and the basis for, and problems with, bare-root planting are discussed. An alternative tree establishment system, involving the precision setting of a bullet-like container enclosing a seed, is proposed. The case for this theoretical system is argued on the basis of its potential biological equality with bare-root planting, which the author considers to be sufficiently promising to be worthy of field investigation, and its suitability to total mechanization. Some possible costs of the system are calculated and potential benefits are postulated. It is concluded that the concept is worthy of careful field study in New Zealand. / Forestry, Faculty of / Graduate

Applying the New Zealand Performance Based Design Fire Framework to Buildings Designed in Accordance with NFPA5000

Yip, Chin Hung (Marco) January 2011 (has links)
A framework for performance based fire design is in the process of being developed by the Department of Building and Housing and such a framework may become a compulsory methodology for performance based fire design in the future. The framework has been developed with the intention of providing a similar level of safety to a building as if the building is designed in accordance with the New Zealand compliance document C/AS1. Ten design fire scenarios have been included in the framework to ensure buildings will be challenged. Design fires for particular building uses, tenability criteria for occupant safety, detector criteria to determine detection time and pre-movement time for egress calculation have been specified in the framework. In order to provide a comparison of the framework against the international building code, three complex case studies have been applied to buildings designed in accordance with NFPA5000 and investigated using the input values and methodologies described in the framework. The case study buildings selected are a retail warehouse, a hospital and a shopping mall. The selection of the buildings was based on complexity of building layout, likelihood of rapid fire growth and high occupancy. Zone modelling (BRANZFIRE modelling) and Computational Fluid Dynamics (Fire Dynamic Simulation modelling) have been utilised in an Available Safe Egress Time (ASET) and Required Safe Egress Time (RSET) analysis. Results of the research showed that the framework provided a robust and consistent method for performance based fire design and the guidance provided in the framework gave a clear methodology to determine the ASET and the RSET. In additional, the framework provided an even more restrictive requirement than the prescriptive requirement in the NFPA5000 in relation to external walls fire resistance and mezzanine floor fire resistance. Conversely, it provided a too relaxed requirement than the prescriptive requirement in the NFPA5000 in relation to means of egress and fire/smoke compartmentation.

The biology of the New Zealand Falcon (Falco Novaeseelandlae Gmelin 1788)

Fox, Nicholas Christopher January 1977 (has links)
This study was undertaken for two reasons. The first was that the New Zealand Falcon was largely unstudied, and research on its basic biology would provide a base-line for further work. The second was that the topic covered a number of disciplines which meant that, as an academic exercise, the scope was broad rather than narrowly specialised. The easiest projects to write up are those in which there are so many data that the figures almost speak for themselves or those in which there are so few data that one is free to speculate. Unfortunately most of the chapters in this study fall into a middle category in which the samples are small and statistical probabilities are marginal. Also, in trying to maintain a broad approach I have been compelled to sacrifice depth and so each chapter tends to reveal more questions than it answers. While writing, I have been acutely aware of the differences between potential readers. Overseas raptor specialists on the one hand may know little about New Zealand's avifauna and ecology, and New Zealand biologists, familiar with New Zealand, may know little about the ways of raptors. Therefore a short glossary of terms has been included. Briefly, the study has set out to answer a few straightforward questions such as 'Is the Falcon monotypic?', 'What is it related to?', 'Why are the females larger?', 'What do they eat?', 'How do they hunt?', 'How big is their range?', 'What is their breeding biology?', 'Will they breed in captivity?', 'What do they die of?', 'Where are they?', 'How many are there?'. Some of these questions, such as the diet, can be answered with some precision; others, such as the problem of sexual dimorphism, can only be answered in a general way. Because I was strongly advised at the start of this project that a study of the New Zealand Falcon was not feasible, I started a subsidiary project on the Australasian Harrier (Circus approximans). This was soon abandoned and although the results have been published (Fox 1977b) they have not been included in this thesis. Certain portions of this thesis, such as 'Rangle' (Chapter 5.15 -5.19), 'Diet values and food consumption' (5.8-5.11) and 'The shape of nesting territories' (8.9) have already been published or are in press, but for the sake of continuity have been kept as an integral part of the thesis. To a certain extent I have been handicapped by lack of raptor specialists in New Zealand with whom I could discuss my work. Another aspect of New Zealand's isolation is the difficulty in obtaining certain literature. Thus Chapter Four has suffered from my not having access to Noel Snyder's and James Wiley's recent monograph on Sexual Dimorphism. The compensation for this isolation has been the' privilege of working on such a magnificent, and unstudied, raptor.

Constructing, contesting and consuming New Zealand's tourism landscape: a history of Te Wairoa

Bremner, Hamish Unknown Date (has links)
The thesis focuses on documentation regarding the historical growth of tourism at Te Wairoa, Rotorua, New Zealand. Te Wairoa acted as a gateway to Otukapuarangi and Te Tarata of Rotomahana which represented an iconic tourism landscape in the nineteenth century. A theoretical engagement with tourism studies and the utilisation of history as an analytical device reveals that the consumption of the tourism landscape is an ongoing, contested, and negotiated cultural construction of place.The history of tourism development at Te Wairoa exhibits the entrenchment of European colonial power in New Zealand. However, within the structures of colonial authority, strategies of survival for the colonised are employed. In this particular case, the strategies include the engagement with Western ethics of capitalism, the manipulation and appropriation of symbols of the 'other', and the control of access through land ownership. The economic and social development of Te Wairoa, based on a tourism economy, also highlights the existent tensions in both a colonial and post-colonial relationship in New Zealand.The research further argues that individual tourism sites reflect culturally ascribed values associated with place. As the combination of exogenous and endogenous social, cultural, political and economic forces evolve so to does the production and consumption of the tourism landscape. Evidence for these considerations is provided by publicly available historical material including archival documents, historical literature, contemporary accounts, newspapers, and government records. The result is an in-depth study which provides an original and thematic interpretation of the history of Te Wairoa as well as supporting a model for investigating change in the cultural construction of place.

'Knowing' sustainable development in the business arena

Byrch, Christine, n/a January 2009 (has links)
A growing knowledge of the human impact on the environment has led to widespread dissatisfaction with the current relationship between industrial societies and the nature that sustains them. From within this milieu, sustainable development has emerged as a term that describes an appropriate relationship in the context of the present time and culture. Although it has been widely adopted by many individuals and organisations, there is little agreement as to what it means and entails. Business has been attributed a significant role in achieving sustainable development. Many have joined the sustainable development debate and received both accolades and critique for their endeavours to interpret and implement the concept within the business sector. Consideration of the prominent and influential role of business in industrial societies, and the lack of definition, elicits the question: what do those people who have taken up the challenge of applying the principles of sustainable development to the business sector think the term means? In response, I have explored participants� subjective knowledge of the meaning of sustainable development within the broad context of humanity�s relationship with nature. In this context, sustainable development is just one of many views of the �proper� relationship incumbent within environmentalism, and which variously critique industrial society�s relationship with nature. A cognitive approach was adopted that suggests how a society views and uses nature arises from its culture; and that an individual�s vision of nature is influenced by their personal environmental worldview, encompassing fundamental beliefs regarding the underlying nature of reality and guidelines for living. The views of forty-eight individuals active in New Zealand�s �sustainable business arena� were investigated. Participants were drawn from businesses purported to be adopting the principles of sustainable development and organisations assisting in this endeavour. Their knowledge was explored by means of cognitive mapping, semi structured questioning, and Q Methodology. Not surprisingly, participants held a variety of normative and subjective understandings of sustainable development that appear to have arisen from �life in general� rather than any external source. Although humanity, the environment, and change were considered central to sustainable development, beyond this were contested notions and priorities as each participant described their vision for the future, each challenging various aspects of our industrial society, to varying degrees. Five ideal-type views were characterised and termed the Societalist, Individualist, Ecologist, Realist, and Futurist views. The five ideal-type views are presented as a typology, constructed from relevant and prioritised worldview beliefs, that highlights the major contradictions. Considered in this way, consensus on the meaning of sustainable development seems unlikely. And perhaps sustainable development is not one thing but instead a reflexive culture of change such that we question how we live. Hitherto, extant sustainable development literature has highlighted the power of business over society. In contrast, in this research, participants reported their attempts to implement sustainable development within business were constrained by society�s requirements and institutions. Further, understanding of sustainable development was observed to be learnt from our culture, highlighting at a more fundamental level, the sway of society on sustainable business.

Tectonic evolution of the Eastern Fiordland Gondwana margin

Scott, James Morfey, n/a January 2008 (has links)
Eastern Fiordland is an eroded Carboniferous to Cretaceous arc assemblage juxtaposed against the Western Fiordland Gondwana continental margin along the Grebe Shear Zone. In the Manapouri region, Eastern Fiordland is composed of scattered metasedimentary and plutonic rocks of Carboniferous, Jurassic and Jurassic-Early Cretaceous age. Quantitative P-T estimates on rare paragneiss assemblages, coupled with LA-ICP-MS analyses of metamorphic overgrowths on detrital zircon grains, demonstrate metamorphism at low to middle amphibolite facies (<6 kbar, c. 600�C) at 145.0 � 2.8 Ma (all quoted errors at 2[sigma]). The Manapouri-Lake Te Anau area of Eastern Fiordland also exposes scattered fragments of the Mesozoic volcano-sedimentary Loch Burn Formation. Relict sedimentary features within this long-lived Early Jurassic to Early Cretaceous unit indicate deposition in a mostly terrestrial or shallow water environment that was fed by debris flows from proximal granitic and volcanic topographic high points. Deposition of the Loch Burn Formation in the Murchison Mountains is bracketed between a 342.3 � 1.5 Ma basal granite and an intrusive 157.6 � 1.4 Ma quartz diorite. Metamorphism throughout the unit achieved greenschist and amphibolite facies temperatures (P unconstrained) in the Early Cretaceous (post c. 148 Ma and prior to c. 121 Ma). Although metasedimentary rocks provide insights into the tectonic evolution of Eastern Fiordland, a range of compositionally heterogeneous plutonic rocks dominates the geology. At Lake Manapouri, these comprise four principal associations: (1) the composite Pomona Island Granite (Carboniferous-Permian and Jurassic), (2) the Beehive Diorite (148.6 � 2.3 Ma), (3) the heterogeneous Hunter Intrusives (Carboniferous, Jurassic and Early Cretaceous) of the Darran/Median Suite and (4) HiSY granitoid dikes of the Separation Point Suite (123.5 � l.2Ma). The latter suite also occurs in immediately adjacent parts of Western Fiordland, forming the Refrigerator Orthogneiss (120.7 �1.1 Ma), the Puteketeke Granite (120.9 � 0.8 Ma) and the West Arm Leucogranite (116.3 � 1.2 Ma). Geobarometry indicates the Jurassic portions of the Darran/Median Suite were emplaced between 4 - 6 kbar and Western Fiordland Early Cretaceous Separation Point Suite between 5 - 7 kbar. Zircon initial �⁷⁷Hf/�⁷⁶Hf isotopic ratios suggest that Separation Point Suite magma could be derived from the same Paleozoic - Late Neoproterozoic mantle source as the Jurassic portion of the Hunter Intrusives member of the Darran/Median Suite. However, Early Cretaceous plutons west of the Early Cretaceous active margin (and study area) have significantly more evolved source regions, reflecting the influence of continental Gondwana on lithosphere composition. Initial �⁷⁷Hf/�⁷⁶Hf ratios from the Loch Burn Formation Carboniferous basal granite zircon are slightly less primitive than either Darran/Median or Separation Point Suite but nowhere near as evolved as similar-aged zircon in the Eastern Fiordland Mt Crescent Paragneiss unit in the Hunter Mountains. The Cambrian/Early Ordovician Russet Paragneiss, which lies just west of the Grebe Mylonite Zone in Western Fiordland and has been intruded by a range of Early Paleozoic to Mesozoic plutons, was metamorphosed at 7.5 � 1.2 kbar, 633 � 25�C at 348.6 � 12 Ma and exhibits no evidence for Jurassic re-equilibration. Zircon U-Pb isotopes from a pelitic schist enclave within the Western Fiordland Mt Murrell Amphibolite are interpreted to show that these and associated intrusive rocks were also metamorphosed at kyanite-grade in the Carboniferous. This event, �M1�, generated a pervasive lineation and distinctive pargasite-anorthite-kyanite/corundum-bearing assemblages in layered aluminous components to the Mt Murrell Amphibolite, garnet-amphibole-biotite-kyanite-gedrite-plagioclase-quartz in metasomatised tonalite at the Mt Murrell Amphibolite margins, and low CaO-garnet in pelitic schist enclaves within the amphibolite. P-T estimates suggest M1 took place at 6.6 � 0.8 kbar, 618 � 25�C. Both the timing and P-T conditions of M1 overlap with metamorphism of the Russet Paragneiss. However, the layered amphibolites and pelitic schist enclaves partially re-equilibrated in the Early Cretaceous (c. 115 Ma) at higher pressure (8.8 � 0.9 kbar). This event, �M2�, generated static assemblages of margarite, epidote, chlorite, oligoclase-andesine and second-generation kyanite in the layered amphibolites and relict olivine gabbronorite, and high-CaO garnet rims, biotite, plagioclase, quartz, kyanite and staurolite in the pelitic schist enclaves. Trace element chemistries of c. 340 Ma zircon grains in the schist have unusual smoothed Ce/Ce* anomalies and high Th/U ratios. These properties may be result of fluid flow and metasomatism from the enveloping amphibolite during imposition of the penetrative M1 lineation. Early Cretaceous (c. 115 Ma) zircon overgrowths and chemistries (low heavy rare earth elements, low Th/U ratios, large Eu/Eu* anomalies) are compatible with formation in the presence of local M2 garnet and plagioclase. M2 was coeval with amphibolite to garnet-granulite facies metamorphism of the regionally extensive Western Fiordland Orthogneiss and Arthur River Complex, thus demonstrating that high-pressure metamorphism was not restricted to the Western Fiordland Early Cretaceous components and their marginal metasedimentary rocks. The Grebe Mylonite Zone forms a lithologic, metamorphic, isotopic and structural boundary between Eastern and Western Fiordland. This 200 to 300 metre-wide and > 50 km long north-striking mylonitic zone is the prominent manifestation of deformation associated with the wider (c. 30 km) Grebe Shear Zone, which extends into Eastern and Western Fiordland. Qualitative and quantitative P-T estimates indicate the currently exposed level of the Grebe Mylonite Zone was active at amphibolite facies conditions (c. 600�C and c. 6 kbar). Coupled U-Pb and Ar-Ar data indicate the mylonite zone was active at, or between, c. 128 and 116 Ma. Temperature-time profiles constructed along a transect perpendicular to the shear zone, used in conjunction with fabric data and the orientation of nearby Tertiary unconformities, suggest that the currently sub-vertical shear zone was rotated during the Cenozoic from an initially steeply east-dipping geometry with a reverse sense of shear. This style of deformation is consistent with an inclined continuously partitioned transpressional structure. Synkinematic emplacement and deformation of the Refrigerator Orthogneiss implies that Grebe Shear Zone provided a crustal anisotropy that facilitated the movement and emplacement of some Separation Point Suite magmas through the crust. Data collected here are interpreted to show that the Grebe Shear Zone is a terrane-bounding suture. Differences in metasedimentary rock composition, age, provenance and metamorphism across the zone suggest that the crustal framework to Eastern Fiordland did not forth in its current tectonic position. Instead, the Mesozoic portion of Eastern Fiordland is inferred to have developed allochthonously with respect to Western Fiordland, with components internally dismembered and rearranged during Jurassic metamorphism and juxtaposition in the Early Cretaceous. However, the Jurassic portion of the arc may have developed near the Gondwana margin because the Jurassic Borland Paragneiss contains detritus that can be partly matched to sources in the Western and Eastern Provinces of New Zealand, as well as early parts of the Darran/Median Suite and Loch Burn Formation. Recognition that the Eastern Fiordland arc was faulted against and then over Western Fiordland in the Early Cretaceous provides a possible driving mechanism for coeval transpressive shortening, rapid burial and high-pressure metamorphism (e.g., as seen in the Mt Murrell Amphibolite) of the lower Western Fiordland crust.

Power, politics and policy : creating, deploying and resisting meaning in New Zealand public sport policy

Piggin, Joe, n/a January 2008 (has links)
All policy involves the transmission of language and ideas and therefore power. Public sport and recreation policy, through which millions of tax dollars are allocated and which disseminates knowledge and understandings about sport and recreation, is one arena where power relations are constantly formed, reformed and challenged. To understand more about the exercise of power in New Zealand sport and recreation policy, this research examines the dissemination and challenge of policies written by Sparc (Sport and Recreation New Zealand), the organisation responsible for public sport and recreation policy in New Zealand. Three questions were used to understand the exercise of power in New Zealand public policy. These questions included: How is knowledge about sport and recreation produced and disseminated through public policy? How is �the truth� about sport and recreation proclaimed and constructed in public policy? How can individuals affected by sport and recreation policy challenge existing relations of power? Theoretically, this research draws on Foucauldian conceptions about power, knowledge, truth and the self. Foucault argued that individuals and groups exercise power discursively, by promoting and deploying certain dominant discourses (or understandings) to the exclusion of other (subjugated) knowledges. As such, the way in which individuals within a society understand knowledge, truth and the self is governed by dominant discourses, and is continually formed discursively over time. Discourses are deployed through a variety of means, including the writing, implementation and resistance of public policy. Methodologically, the thesis merges Foucault�s archaeological and genealogical approaches to studying discourses. Further, it is guided by a critical discourse analysis, which enables the researcher to question the assumptions behind policy discourses. Data is gathered from various sources, including policy documents, public debate over policy, media articulations of policy and interviews with individuals involved in the writing and resistance of public policy. This research highlights four distinct practices (or techniques) that illustrate how power is exercised in public sport and recreation policy. These techniques include an analysis of bio-power, techniques used to analyse, control, and define the body; governmentality, which dictates the range of possible actions of individuals and citizens; games of truth, through which �the truth� is part of a constant discursive debate; and parrhesia, a practice through which citizens can lessen the effect of dominant discourses on their lives. These practices are analysed through specific case studies within the discursive terrain of public sport and recreation policy. With each case study both theoretical considerations and practical suggestions for policy making are offered. Four findings are discussed. Firstly, public policy can discursively and problematically construct understandings of the world through policy goals and measurements. Secondly, the thesis suggests that while public sport and recreation policy is often defended by policy makers as scientific and rational, its writing and implementation is formed by a number of other understandings which cannot be reconciled with the espoused, positivist logic. Thirdly, the thesis suggests that because policy writing is an ongoing process, and because of changing social conditions, �the truth� about particular policies is also susceptible to change. Fourthly, despite protestors of public policy often believing their resistance is in vain, this study suggests that their efforts do appear to influence the subsequent writing of policy. The research concludes with reflections about the problematic discursive effects of public policy as well as a consideration of the potential for groups and individuals to challenge or resist understandings about sport and recreation which they do not agree with. In turn, it offers recommendations about the future development of sport public policy, as well as a reflection of this particular type of research approach used. Finally, using this research as a pivot point, sites for future research are considered. In particular, an examination of the effect of public policy on individuals� lived experiences (as distinct from communities or nations) might be of interest, as would an investigation of effects of global discourses about sport, recreation and physical activity on national public policy.

New Zealand fossil penguins : origin, pattern, and process

Ando, Tatsuro, n/a January 2007 (has links)
Penguins are middle- to large-sized sea birds and are widely distributed in the Southern Hemisphere. They have completely lost the capability for the aerial flight, but are highly efficient wing-propelled swimmers and divers. They have a long fossil record over 60 million years, and their origin could possibly extend back to the late Cretaceous. This study aims to elaborate the course of penguin evolution and driving force of changes based on fossil records of penguins. Numerous fossil penguin specimens have been collected and studied from New Zealand, Antarctica, South America, Australia, and Africa. Studies on fossil penguins have spanned about 150 years history since Huxley (1859). Previous works on fossil penguins have achieved excellent results, but at the same time, left considerable confusion on taxonomy and anatomical interpretation, mainly because of the poor nature of the penguin fossils in early studies. Examination of newly found materials and updated evaluation of previously studied materials are needed, using modern methods. During about 150 years of fossil penguins study since Huxley1859, more than 40 genera and 70 species have been described. The number of specimens listed in the published literature amounts to more than 1300. Chapter II reviews all those fossil penguins in a summarised and consistent style, aiming to present the taxonomy used in this study as a primary and essential resource for research. The chapter also provides other information on fossil penguins, such as geological data and an assessment of the skeletal association of the specimens referred to a species. Chapter III introduces the osteology of penguins, by describing and comparing the skeletal characteristics and variation of both extant and fossil species. Though previous works on penguins osteology are extensive, the interpretation of the homology, and resulted terminology, are occasionally inappropriate, or incorrect, because of the highly-specialised structure. Many of the new, yet undescribed, fossils prompt a comprehensive update of those previous studies, to understand the nature of morphological variation in penguins, and to correct or clarify confusion in previous works. The New Zealand fossil penguin fauna is one of the most significant for fossil penguin studies, but there are many undescribed fossil penguin specimens. Chapter IV provides accounts of such materials. Chapter IV also reviews previously-described New Zealand fossil penguins, usually re-evaluated using new materials. This chapter includes reassessment of the controversial, first-described fossil penguin Palaeeudyptes antarcticus, description of an enigmatic new species (Pakudyptes hakataramea gen. et sp. nov.) which could elucidate the evolutionary pattern of the penguin wing, description of new materials of Platydyptes revealing a unique structure and functional interpretation, and redescriptions with functional interpretation of Pachydyptes and Archaeospheniscus. Published relationships within penguins have not been adequately discussed but stated within rather rough frameworks, so that the relationships within penguins were unclear. Chapter V provides an explicit framework for the phylogeny of penguins. Osteology-based cladistic analysis was performed to seek out the relationships within penguins, using observations on both extant and fossil penguins. There are several important grades in penguin history, which are structurally distant from each other. Results also agree with the published views in which the extant penguins form a rigid group, but Simpson�s subfamily groupings are only partly supported. A postulated phylogenetic tree includes all known fossil penguin taxa including un-named ones. Chapter VI, as a synthesis of contents of previous chapters, provides a broad interpretation of penguin evolution through the Cenozoic: origin, body size increase, demise of 'giant penguins', and the emergence of modern penguins. The chapter gives a global picture of the interaction of penguins, pinnipeds, cetaceans, and temperature and sea-level change. Two main sections are: 'Origin of penguins' and 'Evolutionary process of penguins.' The loss of aerial flight and increase of body size were possibly triggered by the K/T mass extinction event which drastically reduced the predatory pressure for early penguins. The 'giant penguins' survived until the Late Oligocene but declined as the oceans modernised, and new forms of whales with advanced feeding function appeared. There is controversy about appearance of modern penguins. The fossil-based hypothesis (relatively recent origin for crown-penguins) contradicts the molecular-based one (ancient origin for crown penguins), though 'hard evidence' at present does not easily refute either hypothesis.
