Item The profitability of beef production on some New Zealand sheep farms : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Farm Management at Massey University(Massey University, 1971) Lowe, Kevin I.New Zealand sheep farmers are currently receiving product prices which, when considered in relation to their farm costs, are the lowest they have been for many years. Wool prices appear unlikely to recover to levels experienced ten years ago and many sheep farmers are still relying on wool as a major source of farm income. There is an increasing awareness that beef animals can no longer be regarded as aids to good sheep husbandry and instead, must make a direct contribution to farm income. The increasing acceptance of animals of dairy origin as beef-producers, and continued confidence in the long-term market for beef, have helped provide a climate for large-scale moves toward beef-production on many New Zealand sheep farms. As a consequence, there has been a rapid increase in demand for economic information on all aspects of beef production and particularly with relation to established sheep enterprises. It is intended that this thesis shoud go some way towards meeting this demand. [From Introduction]Item Growth studies with lettuce (Lactuca sativa L) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Horticultural Science in Plant Science at Massey University(Massey University, 1974) Lee, Kong KianIn a sand culture experiment carried out in a heated glasshouse, the effect of five levels of P (ranging from 7.75 p.p.m. - 124 p.p.m. on the growth of two cultivars of lettuce was examined. Samples were taken at weekly intervals for ten weeks and growth analysis, and chemical analysis of the whole plant were carried out for total N, P and K from the samples. Significant differences between cultivars were found for net assimilation rate and leaf area ratio, with a slightly higher relative growth rate in young 'Cobham Green' plants. 'Cobham Green' had a greater leaf area ratio but smaller net assimilation rate than 'Webb's Wonderful' . The higher relative growth rate of Cobham Green at the early stages of growth was mainly due to its higher leaf area ratio, but net assimilation rate became an important component during later growth stages, possibly as a result of mutual shading. Within each cultivar, however, the variation in relative growth rate was based on net assimilation rate rather than in leaf area ratio. Both dry weight and the percentage of total P increased with increase in P supply. The percentages of total N and K decreased towards the market maturity but no general trend was observed in the percentage of total P.Item A preliminary investigation of the Pohangina Valley river terraces : a dissertation ... for the degree of B.A. (Hons.) in Geography at Massey University(Massey University, 1976) Challands, Keith In/aItem Saving the children in New Zealand : a study of social attitudes towards larrikinism in the later nineteenth century: A research exercise presented in partial fulfillment of the requirements for the degree of Bachelor of Arts with Honours in History at Massey University.(Massey University, 1975) Gregory, Penelope AnnA concern for the wayward nature of the younger generation would seem to have been a fairly constant theme in the history of society. This research exercise explores the attitudes of articulate New Zealanders towards the problem as it appeared to them in the late nineteenth and early twentieth centuries. [From Preface]Item Palmerston politics : a study of a single electorate, 1905-11 : a research exercise presented in partial fulfilment of the requirements for the degree of Bachelor of Arts with Honours in History at Massey University(Massey University, 1977) McLeod, John ReginaldThe Liberal enigma - a massive victory in 1905 to defeat seven years later - has proved fascinating for historians particularly those at Auckland University in the 1950's and 1960's. The work produced varied from studies of the Dominion as a whole to those of a particular region. It seems logical to take this one step further and to analyse a single electorate. The advantage of a single electorate study appears to lie in observing national politics at its lowest denominator. The question is, did the politics of Palmerston centre on localism, local figures and local concerns, or on party politics and its cohesion and discipline. [From Introduction]Item The design and implementation of a structured programming language with few arbitrary restrictions : the compilation phase : a dissertation presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University(Massey University, 1973) Simpson, Nola MThis thesis outlines the design and implementation of a structured teaching language with particular emphasis on the compilation phase. This language, which has been called MUSSEL (Massey University Structured Student Language) is intended for instruction of first year Computer Science students. In this respect it is a language which is as free as possible from arbitrary syntactic restrictions and is in a form that the student should find both easy and natural to write, with a minimum incidence of programming errors. It is evident that the language a student uses profoundly influences the way he develops his techniques and habits of construction of algorithms. MUSSEL has been designed with this influence in mind and has been deliberately designed as a structured language i.e. the language reflects the basic structure of programs, so that algorithms can be refined and expressed naturally in it. In this sense MUSSEL aims to teach the student programming as a constructive intellectual discipline rather than just as a tool to communicate with the computer. MUSSEL has been implemented as an interpretive system i.e. during the compilation phase the source language is translated into an intermediate language, which, is then interpreted. The reasons influencing this type of implementation are the need in a teaching language to minimise compile time and to maximise diagnostics, both at compile-time and at execution-time.Item An economic evaluation of the Thai-New Zealand feeder road in Northeast Thailand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science(Massey University, 1973) Askwith, John ETransport has been identified as an essential element in a comprehensive regional development programme and economic, social, and political benefits can result from the construction of a road in a developing region. This study investigates the economic impact of a road construction project in Northeast Thailand. The Thai-New Zealand feeder road, a 144 kilometre paved road, was completed in 1971 and links five major towns in two provinces while passing through a region of populated villages. Nearly all households in this region engage in agricultural production. The rice crop is the most important factor affecting the welfare of a household and the quantities of produce sold from other enterprises are small. Purchased inputs, aside from small quantities of fertilizer, are not commonly used. This study has been undertaken only two years following completion of the road, although the first 36 kilometre section had been completed five years. The collection of data from households in villages adjacent to the road is deserined and the data obtained is discussed in relation to the characteristics and measurements of subsistence agriculture. Traffic usage of the road was measured in two surveys and a land classification survey was conducted to estimate the agricultural development that has taken place since road construction began. A large part of the study is devoted to a description of the agricultural enterprises practised in the region, the problems preventing economic development, and the potential for further development following construction of the Thai-New Zealand feeder road. This data has been used to assess the impact of the road at the present time and the likely impact under various conditions which might eventuate in the future. Methodology for a standard benefit-cost analysis has been used in the evaluation of the road. The three economic criteria, net present value, benefit-cost ratio, and project internal rate of return have been applied to the discounted cost and benefit flows. Together with those items that can not be quantified, these three criteria have been used to evaluate the profitability of the project. Construction of the Thai-New Zealand feeder road should be regarded as the provision of one input essential for economic development in the region. Other inputs will be necessary before the full benefit of the road can be obtained. The road has already had a significant economic impact and if the potential from the application of improved technology and practices within existing agricultural enterprises can be realised, the road will have an even greater role in the economic development of the region.Item Computer system development and investigation of a digital control technique : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Systems Engineering at Massey University(Massey University, 1977) Chong, Nee FondThis thesis concerns the implementation of direct digital control, using a PDP/8F minicomputer. The project has been undertaken to gain a better understanding of certain aspects of the control theory used, and also the effective use of the minicomputer. The use of this system in the laboratory for the control of a typical system is described. Direct digital control (DDC) is becoming increasingly important and is often replacing analog means using three-term controllers. Digital control is applied to a continuous process, which is sampled and processed as discrete time data. The z-transformation procedure is especially convenient and useful in the analysis of these systems. [From Introduction]
