Diversification and expansion in large diversified New Zealand companies : a thesis presented in partial fulfillment of the requirements for the degree of Master of Arts in Geography at Massey University

Diversification and spatial expansion are investigated in relation to eight Type III companies in New Zealand. The case companies are delimited on the basis of a three stage classification of corporate growth and organisation. The conceptual background to the thesis also includes an examination of more general aspects of corporate decision making, strategy, and the expansion and impact of firms in space. Two areas of research are examined - (a) the incidence and nature of diversification in the eight companies, and (b) spatial aspects associated with diversification and expansion. A case study approach is used to outline the diversification and spatial expansion of the companies over time. A three-fold classification of diversification is proposed: diversification within and between activity groups and diversification function. Diversification is then viewed in relation to the respective growth developments of the case companies. On the basis of these accounts, a number of conclusions are drawn on the temporal development of diversification in the spatial expansion of the eight companies. Diversification was found to be an important component in the corporate growth and geographic expansion of the case companies. Furthermore, a review of the geographic distribution of their activities suggests the companies have an important contribution to national and regional development in New Zealand

Quantitative measurement of the composition of Al_xGa_(1−x)As heterostructures using a simple backscattered electron detector

We describe a technique for the quantitative measurement of composition in Al_xGa_(1−x)As heterostructures using a simple solid‐state backscattered electron detector in a scanning electron microscope. Calibration data are presented and are shown to be consistent with the Castaing [Adv. Electron. Electron Phys. 13, 317 (1960)] theory. The technique is applied to image representative Al_xGa_(1−x)As heterostructures including a graded index separate confinement heterostructure (GRINSCH) laser structure

Power line communication systems for industrial control applications

For almost as long as the electricity distribution industry itself has existed, so also has the idea of utilising the transmission grid, be it over a wide area or on a local basis, for the transmission of 'intelligence'. This might be in the form of voice transmissions, or for the purposes of monitoring or controlling electrical devices attached to the network. This thesis specifically concerns itself with the potential applications of power-line-carrier (PLC) communications technology within the field of industrial plant/equipment control, as it is within this field that the author works. We look at the entire subject area of industrial control, starting from a historical viewpoint, and consider the special needs and requirements that a proposed PLC solution must offer for this application, especially based on the noise conditions likely to be experienced on a `real' power line. A proposal is made for a `Power Bus', intended for use within certain areas of industrial control, and decisions are made based on the projected link response times for such applications. The experimental phase of the research is practical in nature and consists of a raft of tests and evaluations of the performance of power line modem technologies, under controlled and repeatable noise conditions. To complement these results, further tests are carried out under `real world' conditions, within an actual factory environment. Based on the results of all of these tests, the suitability of a PLC solution for this type of industrial control application is considered. The Thesis concludes with a look at recent developments in, as well as the future of, Power Line Communication techniques

Laser power-meter comparison at far-infrared wavelengths and terahertz frequencies

We have evaluated the responsivity of seven different thermal detectors compared to an electrically calibrated photoacoustic reference detector at 119 µm (2.5 THz) and 394 µm (0.76 THz) laser wavelengths. Among the thermal detectors is an electrically calibrated thermopile having a vertically aligned carbon nanotube array as the absorber. We document the uncertainty contributions attributable to the photoacoustic reference detector along with a definition of a calibration factor based on the measurement protocol. The expanded relative uncertainty (k = 2) and a calibration factor of each detector are tabulated

Counting People and Making People Count: Key Sources of Population Projections

This literature review is the first section of a two part literature review in to population dynamics. The literature review attempts to answer the question, "What are the key sources of information on population dynamics globally and for the countries and regions where DFID works?"This literature review is the first section of a two part literature review in to population dynamics focussing on a review of key global information sources. Three sources of centrally generated projections exist: The Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat, the World Bank and the Wittgenstein Centre. As the World Bank relies heavily on the UN its role will not be considered. The premier source of population projections is the UN Population Division. This data is easily accessible and updated every two years. Five global datasets are produced by the Division (i) World Population Prospects, (ii) World Urbanisation Prospects, (iii) World Population Policies, (iv) Estimates of family planning indicators and (v) Estimates of the number of international migrants

Counting people and making people count: Implications of future population change for sustainable development

This literature review is the second section of a two part review in to population dynamics. This second section of the review attempts to address what are the most significant implications of these dynamics for international development, as currently articulated in the most up-to-date literature.The following summary is taken from the Key Findings of the 2015 Revision of the UN Population Division’s World Population Prospects (United Nations Department of Economic and Social Affairs Population Division, 2015) and is purely to provide an overview of future population change. The global development challenges of future population change are broad and a comprehensive review is beyond the scope of this pilot learning journey. This report instead focusses on the areas highlighted by DFID at this stage of the journey with the addition of addressing the fertility challenge
