Military Preparedness in a New Security Environment: The Canadian Army Reserve's Contribution to Public Safety and Domestic Security addresses the Reserve's response to Canada's domestic security needs in the current security environment. The security environment is evolving, which has led to increasing constraints and the search for evolving security solutions for Western national governments, including a greater use of the Reserve. However, certain tensions inhibit the twin-track contributions of the Reserve to both domestic and international operations, arising from issues such as role definition, buy-in, and resource commitment. The "Canadian solution" o f having the Reserve "muddle through" these issues and follow both roles will inevitably need to change if the Reserve is to effectively serve Canadians in the future, be that internationally or domestically. The methods employed include the analysis of existing literature addressing the evolving security environment, concepts of civil-military relations, and recent Canadian national security policies, combined with a presentation of the Army Reserve, and a comparative study with key Commonwealth counterparts. Thus, at a conceptual level, at the Canadian level, and at the level of Canada's international partners, it became apparent that there are tensions between a domestic and international role for the Reserve which could create problems for the Reserve's future. In practice, the methodology consisted of the analysis of academic and government primary and secondary sources as well as drawing upon the author's interviews with individuals of relevant expertise or experience. / Arts, Faculty of / Political Science, Department of / Graduate

This research investigates whether the South African Energy Regulator (NERSA) correctly prices the cost of equity, through looking at the petroleum storage sector. A model is built to simulate the current methodology for tariff setting and historical data is used to estimate the returns a regulated firm would have earned over the past 25 years. In addition, a benchmark cost of equity is calculated through a sample of US firms. Integrated firms are then decomposed to their revenue generating segments and cost of equity per segment is then estimated. The study finds that the methodology calculates a return lower than that earned by the market (measured through the J203). The study further finds that the risk to which the regulated company is exposed to, defined in terms of variability of retunes, is not significantly different than that of the market. Lastly, the study finds that the benchmark cost of equity is significantly higher than that calculated by the Regulator. Recommendation for Regulator consideration as well as for further research are provided. / Dissertation (MBA)--University of Pretoria, 2014. / lmgibs2015 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

Capitalism has evolved globally by disciplining its key features to suit new markets and changing socio- economic environments. These features include private property, labour and neoliberalism. Whilst capitalism has managed to become a well-established system, occasionally it is confronted with challenges which expose its callous nature. In South Africa, land restitution calls into question capitalism's operation as it disrupts the conventional process of profit accumulation. This is evident when looking at the manner in which land claims are settled in private nature reserves that are under a land claim. Private nature reserves have been structured to bring together capitalism's key features of property, labour and neoliberalism and therefore become interesting sites on which to study how they react to land restitution. This study uses Mala Mala Game Reserve to investigate how capitalism unfolds in the game reserve. It specifically looks at the conservation business, labour conditions, and the settlement of the land claim in the reserve. It begins by analysing the structuring of the conservation business to fit capitalism's objective of profit accumulation. The emphasis here is on the relationship between capitalism and nature, and how the conservation business is built on the commodification of nature. It traces the business foundation of Mala Mala over time to understand how the reserve became a luxurious safari destination that target a small, select group of wealthy, mainly international tourists. The reserve promises quality wildlife viewing and luxury accommodation for its guests, which it is able to offer through the commercialisation of nature in a manner that is often viewed as ethical to the greater public, yet a closer look at the operation of the reserve shows the unaccounted cost of exclusion, dispossession and exploitation. These impacts are further contextualised in the second part of the study, which documents the structuring of labour as a condition for building the reserve's economic success. Labour is an important necessity for capitalism's operations and its conditions show us the fierce manner in which surplus value is extracted. The creation of the cheap labour system in South Africa played an important role in building conservation areas. The success of conservation business in private nature reserves routinely depends on conservation labour. The study finds that cheap labour in Mala Mala is secured through the adoption of a migrant labour system. Such a system highlights the social ‘cost' (labour) of capital accumulation that takes place in the reserve. While the first two parts of the study explain how capitalism has shaped the conservation business in Mala Mala, the last section investigates what happens when this almost perfectly structured system is challenged through land claims. The study finds that the clash between conservation business and land restitution produce a model of land reform that chime with neoliberalism. Backed by government and landowners, the model separates business ownership from landownership in order to guarantee capital accumulation. This study contributes to our understanding of land restitution in private nature reserves in South Africa and the land restitution model it produces.

The purpose of this study is to aid interpreters in evaluation sources (research material) for use in interpretive presentations and programs in Sequoia and Kings Canyon National Parks. This was done by illustrating the need for source evaluation and then developing the guidelines for selecting, evaluating, and most effectively using various sources in the development of interpretive programs in the National Parks Services (NPS).

‘Crimson Seedless’ (Vitis vinifera L.) is an attractive, late season, red, seedless cultivar, which is currently a very popular table grape cultivar. It is one of the most planted cultivars in South Africa and third in terms of total area of table grape vineyards in production. Mature ‘Crimson Seedless’ grapes are characterized by outstanding eating quality, good flavour, firm and crisp berries. One of the key factors affecting the yield of table grape cultivars is bud fruitfulness. Low fruitfulness can have a significant effect on the yield of table grape cultivars and ‘Crimson Seedless’ is characterized by a fruitfulness problem. Summer pruning, such as the removal of shoots after harvesting grapes, is a cultivation practice widely used by some table grape producers in the Orange River region of South Africa. The first hypothesis of this study stated that the removal of shoots after harvest will increase the transmitted PAR through the canopy, increase carbohydrate reserve levels in canes and improve bud fruitfulness of ‘Crimson Seedless’. A second hypothesis of this study stated that the cut back of all main shoots and shoots developing from spurs to the nearest lateral shoot and the removal of all unproductive shoots after berry set will result in fruitful shoots the following season. The third and final hypothesis of this study stated that the removal of shoots after harvest and berry set will improve the yield and quality of Vitis vinifera cv. ‘Crimson Seedless’. The study was conducted over three seasons (2010/11 to 2012/13) and aimed at investigating factors, including shoot removal, impacting bud fruitfulness of an 11-year-old commercial V. vinifera L. cv. ‘Crimson Seedless’ vineyard, grafted on ‘Ramsey’ (Vitis champinii) rootstocks in the Hex River Valley. The treatment design was a complete randomized design and involved five treatments, which included 33% shoot removal (S33) and 66% shoot removal (S66) after harvest, cutting of all main and lateral shoots developing from spurs to the nearest lateral shoot (LS), removal of all unproductive shoots (RSB) which was compared with the control, in which standard pruning practices were performed. The results obtained in this experiment showed that shoot removal after harvest and after berry set improves PAR transmission into the canopy, but there was no significant impact on bud fruitfulness. In addition, it was found that shoot removal reduced vegetative growth resulting in thinner canes that also led to the improvement in PAR transmission. Furthermore, bunch number per shoot in the LS treated vines was reduced when compared with S33 treated vines, illustrating that shoot removal at berry set can reduce bunch number per shoot due to defoliation after berry set. The significant decrease in bud burst in the S33 treatments compared with the control was expected due to less shoots, resulting in a reduction in cane mass during the 2010/11 season. The significant effect of LS treatments after berry set on TSS and total red pigments compared with the S66 treatments and the control, respectively, clearly indicates that shoot removal after berry set improves grape colour. The positive effect of LS treatments on colour was supported by the significant improvement in class 4 bunches, representing an improvement in quality. Although shoot removal did not have a significant effect on the bunch mass per vine of ‘Crimson Seedless’, there was a significant reduction in total bunches for export and mass of the total export bunches in the LS treatments in the 2011/12 season. A link between carbohydrate concentration in canes and bud fruitfulness was not found in this study, as S33 and S66 treatments did not have a significant effect on carbohydrate content in canes during the 2011/12 season. The question therefore arises whether the treatments applied during the growing seasons are worthwhile, because there was no significant impact on bud fruitfulness of Vitis vinifera L. cv. ‘Crimson Seedless’. This study illustrates that growers need to decide whether it is worthwhile to utilize labour for this practice and they must manage grapevines not only for the current seasons crop, but also for the next season and this can be accomplished by maintaining sufficient carbohydrates for fruitfulness and yield from season to season. / Dissertation (MInst Agrar)--University of Pretoria, 2014. / tm2015 / Plant Production and Soil Science / MInst Agrar / Unrestricted

Nature reserves in the City of Tshwane are under threat from ecological and historically significant decay due to the less defined nature of these landscapes. Architecture in form, function and technology can be developed in the in-between of nature and urban to act as conservator for these nature reserves. Utilizing the natural resources of nature to produce products for the urban dweller within a space that conserves the historical protective layers of the site. The space of interaction between nature and urban becomes the conservator, acting as active protector in terms of sustainable production, education and urban dweller interaction with the nature reserve and its continuous history of protection. / Natuurreservate in die stad Tshwane word bedreig deur ekologiese en historiese betekenisverval weens die minder gedefinieerde aard van hierdie landskappe. Argitektuur in vorm, funksie en tegnologie kan ontwikkel word in die tussen ruimte van natuur en stedelike gebiede om as natuurbewaarder vir hierdie natuurreservate op te tree. Die natuurlike hulpbronne van die natuur kan gebruik word om produkte vir die stedelike inwoner te produseer binne ‘n ruimte wat die historiese beskermende lae van die terrein laat voortduur. Die ruimte van interaksie tussen natuur en stedelike word die bewaarder, wat optree as ‘n aktiewe beskermer in terme van volhoubare produksie, opvoeding en stedelike inwoner interaksie met die natuurreservaat en sy voortgesette geskiedenis van beskerming. / Mini Dissertation (MArch(Prof))--University of Pretoria, 2018. / Architecture / MArch(Prof) / Unrestricted

This dissertation consists of three essays on international capital flows. The first chapter documents the accumulation of foreign exchange reserves and the simultaneous increase in the foreign direct investment (FDI) for emerging market economies. The second chapter discusses the performance of FDI firms and domestic firms in creating jobs using firm-level data from Orbis. The third chapter studies the proper exchange rate and monetary policy when emerging market economies denominate their external debt in foreign currencies. In Chapter 1, I study why emerging market economies hold high levels of foreign exchange reserves. I argue that foreign exchange reserves help emerging markets attract foreign direct investment. This incentive can play an important role when analyzing central banks' reserve accumulation. I study the interaction between foreign exchange reserves and foreign direct investment to explain the level of reserves using a small open economy model. The model puts the domestic entities and international investors in the same picture. The optimal level of the reserve-to-GDP ratio generated by the model is close to the level observed in East Asian economies. Additionally, the model generates positive co-movement between technology growth and the current account. This feature suggests that high technology growth corresponds to net capital outflow, because of the outflow of foreign exchange reserves in attracting the inflow of foreign direct investment, thus providing a rationale to the `allocation puzzle' in cross-economy comparisons. The model also generates positive co-movement between foreign exchange reserves and foreign debt, thus relating to the puzzle of why economies borrow and save simultaneously. In Chapter 2, joint work with Sakai Ando, we study whether FDI firms hire more employees than domestic firms for each dollar of assets. Using the Orbis database and its ownership structure information, we show that, in most economies, domestic firms tend to hire more employees per asset than FDI firms. The result remains robust across individual industries in the case study of the United Kingdom. The analysis shows that an ownership change itself (from domestic to foreign or vice versa) does not have an immediate impact on the employment per asset. This result suggests that different patterns of job creation seem to come from technological differences rather than from different ownership structures. In Chapter 3, I investigate how the devaluation of domestic currency imposes a contractionary effect on small open economies who have a significant amount of debt denominated in foreign currencies. Economists and policymakers express concern about the "Original Sin" situation in which most of the economies in the world cannot use their domestic currencies to borrow abroad. A devaluation will increase the foreign currency-denominated debt measured in the domestic currency, which will lead to contractions in the domestic economy. However, previous literature on currency denomination and exchange rate policy predicted limited or no contractionary effect of devaluation. In this paper, I present a new model to capture this contractionary devaluation effect with non-financial firms having foreign currency-denominated liabilities and domestic currency-denominated assets. When firms borrow from abroad and keep part of the asset in domestic cash or cash equivalents, the contractionary devaluation effect is exacerbated. The model can be used to discuss the performance of the economy in interest under exchange rate shocks and interest rate shocks. Future directions for empirically assessing the model and current literature are suggested. This assessment will thus provide policy guidance for economies with different levels of debt, especially foreign currency-denominated debt.

The concept of geopark was first proposed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1999. After that, geotourism emerged as a novel strategy for sustainable development in rural areas. Tourism carrying capacity is a concept related to the optimum use of natural areas without creating environmental degradation. This concept has been widely employed in nature tourism in national parks. To apply the carrying capacity concept in global geoparks, the purpose of this study is to remodel existing tourism carrying capacity frameworks to foster sustainable use of global geoparks. A review of the development of carrying capacity concept and six tourism carrying capacity frameworks, namely, Recreation Opportunity Spectrum (ROS), Limits of Acceptable Change (LAC), Visitor Impact Management (VIM), Visitor Experience and Resource Protection (VERP), Visitor Activity Management Process (VAMP), and Tourism Optimization Management Model (TOMM) in Chapter 2 demonstrates that tourism carrying capacity concept is able to raise the awareness on sustainable tourism in national parks but these traditional tourism carrying capacity frameworks commonly failed to address the interests of all stakeholders. Thus, this thesis adopts the definition of tourism carrying capacity for geoparks as the situation or condition of a geopark where there is reconciliation (i.e., having balance and harmony) of environmental conservation, social maintenance, and economic development. Based on the three aspects (i.e., environmental conservation, social maintenance, and economic development) of this concept, a tailor-made framework for global geoparks was built in Chapter 3, using confirmatory factor analysis and the revised importance-performance analysis to evaluate tourism carrying capacity in Global Geoparks. Then the modified tourism carrying capacity framework was applied in two UNESCO Global Geoparks, namely, Hong Kong Global Geopark and Danxiashan Global Geopark, to address the inherent tensions between resources conservation and sustainable development in both Geoparks in Chapters 4 and 5. It was found that 1) there was compatibility only among the three dimensions, namely, environmental conservation, social maintenance, and economic development in two Geoparks; 2) the structure of the framework and the compatibility of the three dimensions can only be confirmed in the local community model (Figure 3.3) by the importance data of factors, i.e., resource, human environment, and facility. No validity can be established in the construct of the GGN model on the local community's satisfaction of the overall environments in two Parks and neither is there an agreement between the visitors in both Parks with the GGN criteria; and 3) from the satisfaction data on the three factors of the visitor model (Figure 3.4), i.e., environmental carrying capacity, political-economic carrying capacity, and socio-demographic carrying capacity, it shows that HKGP appears to be more sustainably managed than DXSGP. Collectively, this study has provided a new framework for evaluating tourism carrying capacity in a geopark. I hope to advance the methodological innovation of sustainable geotourism management and supplement the lacuna of criteria and standards for Global Geoparks in future studies.
