The choice between purchasing land or entering into a long-term lease is analyzed using a deterministic cash analysis both from the tenant's and landlord's perspective. It is less financially stressful to start farming through a lease agreement than by purchasing the assets. The lease period of landlord indifference between these choices is determined for each combination of input variables. / Land value and income forecasting models are developed and presented. These models are based on two similar but conceptually different statistical tests. Each test results in different forecasting models which has implications for the use of such models in the future. / Consumption-based asset pricing models are tested using agricultural rental income. These models, although appealing both intuitively and theoretically are found wanting in terms of their formulation as the model results are highly sensitive to the data employed. This concern increases with the level of data aggregation.

This thesis is an analysis of the political thought and activities of an Iranian 'alim, SAYYID HASAN MUDARRIS (1870-1938). It demonstrates the continuation of the Iranian 'ulama's struggle, started in late 19th century, against colonialism and despotism during the years after the Persian Constitutional Revolution. This study investigates the deep causes of conflict between Mudarris and Riza Shah, the founder of the Pahlavi regime. Mudarris was a man of God as well as a man of his people. He was a mujtahid with high degree of patriotic sentiments. He devoted his life to Iran and to the dignity of his people for whose freedom from the yoke of Imperialism and despotism he lost his life.

This study is an attempt to bring to light an important Ottoman Turkish work of theosophy entitled Ïtâl]ü'I-l:fikem (Elucidation of Wisdoms), written by Ismall An~aravT (d. 1631) as a commentary on the treatise Hayakil al-Nür (The Temples of Ught) by Shihàb al-Din Suhrawardl (d. 1191). The study consists of three main parts. The first part provides a detailed account of the life and works of the author, An~aravT, with an emphasis on his scholarship in the context of the Ottoman learned class. The second part, which is the main body of this research, presents a chapter by chapter analysis of the significant issues discussed in An~aravl's commentary, in comparison with the commentary of JalaJ al-Dln Oawwani (d. 1502), by whom he seems to be influenced. This section is an investigation of An~aravT's reformulation of Ishrâqi wisdom within the framework of his orthodox mystical views. In the last part, on the basis of ail available manuscripts, which are collated, a reliable text for edition is established. / Cette étude est faite dans le but de faire connaître un travail important de théosophie, intitulé Îzahu-l-hikem(Élucidations des Sagesses) écrit par Isma'il Ankaravi (m. 1631) en turc ottoman comme commentaire du traité intutilé Hayakil al-Nûr (Les Temples de Lumière), écrit par Shi hab al- Dm SuhrawardT (m. 1191). Cette étude consiste en trois parties. La première partie traite en détail de la vie et des livres de l'auteur Ankaravi, en insistant surtout sur sa personnalité intellectuelle dans le contexte de la classe des intellectuels Ottomans. La deuxième partie est la partie la plus importante de cette recherche, elle présente, chapitre par chapitre, une analyse des sujets significatifs discutés dans le commentaire d'An~aravi d'une façon comparée avec celui de Jalal al-DTn Dawwanl (m. 1502), par qui il semble avoir été influencé. De plus, cette section est un approfondissement de la compréhension d'An~aravT, dans le cadre de sa vision mystique et orthodoxe, de la sagesse ishraqie. Dans la dernière partie, tous les manuscrits accessibles sont collationnés en vue d'une édition critique.

From measurements of thermal and electrical conductivities of 64 ocean sediment samples obtained from piston cores taken off the Oregon Coast, and from 37 water-saturated sandstone samples analyzed by Zierfuss and Van der Vliet (1956), as well as 51 thermal conductivities and water contents of ocean sediments analyzed by Ratcliffe (1960), this research shows that a useful relationship can be obtained giving thermal conductivity when electrical conductivity is known. Analysis of the data was made using theoretical concepts which have been known for many years to relate thermal and electrical conductivity to porosity. The results of this research may make possible a convenient determination of in situ thermal conductivity that would give the average conductivity in materials containing large variations in conductivity. / Graduation date: 1966

Sediments on the inner portion of the Oregon continental shelf consist of clean, well-sorted, detrital sand. This sand has an average median diameter of 2.53Φ (. 173 mm) and is both positively and negatively skewed. Deposits with median diameters in the coarse sand and gravel classes occur at depths of 20 to 40 fathoms and probably represent ancient beach or fluviatile deposits formed during lower stands of sea level. The outer shelf and upper slope are covered by poorly sorted sediments with median diameters in the fine sand to fine silt classes. Mean diameters of the sediments are almost always smaller than their median diameters and the sediments are positively skewed. The heavy mineral assemblages are dominated by the amphibole and pyroxene groups and the opaque-garnet association. Pyroxenes are most abundant in the coarser-grained sediments of the inner shelf and decrease in abundance offshore. Amphiboles are most abundant in the finer-grained sediments of the outer shelf and upper slope. Highest concentrations of the opaque-garnet association also are found in the inshore samples. Sediments of the continental shelf are derived from two principal sources, rivers and erosion of coastal terrace deposits. Rivers are probably contributing only fine-grained material to the shelf as much of the coarser fluviatile material is thought to be trapped in the estuaries. The terrace deposits are actively being eroded and are thought to contribute about 21,000,000 cubic feet (.00013 cubic miles) of sediment to the continental shelf annually. Evidence suggests that much of the inner-shelf sand is probably a relict transgressive sheet sand that was deposited during the last rise in sea level. Most of the deposition of the modern sand on the shelf has been confined to the inner portion of the inner shelf. Finer-grained sediments have been deposited on the outer shelf and upper slope. Characteristics of the sediments on the present continental shelves may be useful in identifying continental shelf deposits in the geologic column. / Graduation date: 1966

This thesis is an investigation of why and how homeowners decide to renovate their homes. Energy efficient renovations are of particular interest given their potential contribution to public policy goals including greenhouse gas emission reduction. Policies seeking to improve energy efficiency in existing homes have to influence homeowners’ decisions. This requires a psychologically and behaviourally realistic understanding of the renovation decision process. Different research traditions offer competing models. These are tested through a series of hypotheses on the form and content of the renovation decision. The empirical dataset used combines both stated and revealed preference data. 809 homeowners in British Columbia were surveyed at three different cross-sections of the renovation decision process. The sample included both energy efficient (e.g., windows, insulation) and amenity renovators (e.g., kitchens, bathrooms), and was broadly representative of the population of renovating homeowners in British Columbia. Survey responses were calibrated using actual energy consumption data, and a supplementary survey of realtors. Calibration allowed homeowners’ expectations of the financial costs and benefits of renovating to be evaluated. Firstly, sampled homeowners systematically over-estimated their energy costs. Secondly, these estimates were subject to common information processing and recall biases. Thirdly, even homeowners in the middle of energy efficient renovations had expectations of capital costs, energy cost savings, and property value impacts that were largely unknown or unreliable. More generally, sampled homeowners lacked the basic knowledge necessary to appraise energy efficient renovations as financial investments. Homeowners’ motivations for renovating were more likely to be emotional and aesthetic in the case of amenities, but related to functional outcomes like thermal comfort in the case of energy efficiency. Social norms were influential in both cases but were underreported by homeowners. This was consistent with rationalisation biases which help individuals maintain self-esteem by emphasizing instrumental explanations for their actions. This psychologically realistic characterisation of the renovation decision suggests a range of design criteria for policy, and questions the effectiveness of narrowly-targeted information and incentive policies in their current form. However, policy implications should be generalised with caution given the low energy price and appreciating real estate market characteristics of the study region.
