Masters in Science / Department of Landscape Architecture/Regional & Community Planning / Stephanie A. Rolley / This case study considers the lessons of Ecuador’s Yasuní-ITT initiative for future climate change policy and international conservation and development efforts. A comprehensive post-cancellation history of the initiative and background information regarding key domestic and international actors and institutions is presented in the Literature Review. Documents identified from LexisNexis and Google searches are analyzed to identify seven narratives of the initiative’s failure, which provide a basis for the suggestion of lessons. Questions regarding supply-side climate policy opportunities and challenges are explored. The initiative’s political mismanagement, design omissions and insufficient domestic political efforts, and a lack of contribution incentives are identified as the key causes of failure. The author concludes that the initiative’s supply-side model of shared sacrifices has the potential to align developed and developing country needs in support of greenhouse gas emissions reduction goals while addressing the difficulties posed by an emergent political economy of developing world resource extractivism in Ecuador and elsewhere. Future research regarding supply-side climate policies is suggested.

This thesis describes the results of a three year study which collected larvae of the acorn barnacles Semibalanus balanoides on a rocky coastline in Fife, East Scotland. The nauplii larvae of S. balanoides are released from their parent in springtime in the United Kingdom and develop in the plankton for approximately one to two months. During this period they are transported some distance from the parent population and eventually return to the intertidal shoreline as a cyprid larval stage. The ‘decision’ to settle is a crucial point in the life history of the organism as most sessile organisms cannot move once this has occurred. The supply of larvae to intertidal shorelines was historically neglected until the 1980s. Patterns of settlement were largely considered irrelevant to distribution patterns of adults relative to postsettlement processes such as predation and competition. Despite the resurgence in “supply-side ecology” in the past 20 years there has been little development towards the measurement of larval supply. Consequently there has been very little description of fine scale or large spatio-temporal studies involving larval supply. This study demonstrates the first study directly addressing larval supply independently from larval settlement at mesoscales (metres to kilometres; days to years). Improvements were made to the passive larval trap described by Todd (2003). A conical opening was combined with the spiral trap design and a number of inlet areas were trialled (0.25cm², 0.5cm², 1cm² and 2cm²). These were tested across typical wave regimes measured with a new autonomous pressure sensing wave transducer and the 1cm² inlet was selected as the most appropriate trap design due to a balance between an increased per unit inlet larval capture and sufficient absolute larval capture so as to identify daily variation in larval supply to a site. Larval settlement has been studied extensively and is often used as a direct measure of rates of larval supply. It is widely assumed therefore that rates of settlement are a direct reflection of rates of supply, as long as settlement substrates and adult conspecific responses remain uniform. This thesis provides a means of accurately characterising the supply-settlement relationship for S. balanoides independent of substrate based responses and demonstrates that this is not the case. The relationship was found to be asymptotic, even at sites where there was low larval supply. It was concluded that density-dependent larva-larva interactions were present during the settlement of larvae and were relevant at daily temporal scales, limiting the rates of larval settlement proportional to larval density. There was no obvious effect on this relationship due to wave action however differences were observed between sites and years. Saturation of preferential environments within the tiles was observed resulting in a settlement preference cascade, with larvae being forced to settle in increasingly less preferable areas of the tiles with increasing larval density. Larva-larva interactions are demonstrated as having a considerable effect on the rates of settlement of S. balanoides.

O objetivo deste trabalho é aplicar a metodologia do Planejamento Integrado de Recursos energéticos (PIR) dentro do ambiente corporativo. Para estudo de caso foi escolhida uma indústria de papel e celulose, por se tratar de uma das indústrias de maior consumo energético, e a região onde ela está instalada, o município de Suzano. Inicialmente, procurou-se descrever o processo produtivo em uma indústria de papel e celulose. Para este trabalho foi analisado somente os recursos do lado da oferta. Além dos recursos tradicionais, que são a caldeira de biomassa, a caldeira de gás natural/óleo combustível e as caldeiras de recuperação, foi incluída uma nova tecnologia, a gaseificação de biomassa. Foram descritas as tecnologias de gaseificação disponíveis e mostrado o seu estado da arte. Dentro dessas tecnologias, há uma aplicação que busca substituir as tecnologias atuais de caldeira de recuperação, a gaseificação de licor negro. / The purpose of this study was to apply the Integrated Resources Planning for Energy (IRP) methodology within corporate environment. A study of case of pulp and mill industry was chosen, because it is one of largest energy consumption industries, and the region that was studied was Suzano. Initially we described the industrial process of pulp and mill factory. This study we will analyze only the features of Supply Side Resources. In addition to the traditional power supplies which are biomass boiler, natural gas/fuel oil boiler and recovery boiler, we include a new technology, biomass gasification. We described the technologies available for gasification and show the state of art of this technology. Within these technologies, we have an special application the seeks to replace currently technology of recovery boiler, Black Licor Gasification.

This thesis explores how Mexican fresh produce supply chains have responded to US bio-security regulations designed to prevent the intentional and accidental contamination of imported food. It explores the compliance processes, which are theorised using a framework drawn from the Resource-Based View (RBV) and the Supply Chain Governance (SCG) literatures. The constructs developed herein regarding capabilities and supply chain ‘governance structures' complement previous Regulation Studies (RS) explaining compliance behaviour. The thesis analysed 12 case studies, and tested causal conditions of compliance using a multi-value Qualitative Comparative Analysis (mvQCA) method. The main results show: 1) the pathways to meet the regulatory requirements; 2) the limited diversity of capabilities associated with higher levels of compliance; and 3) the importance of tight supply chain coordination to source and exchange knowledge for compliance, regardless of how or who governs the supply chain. The thesis contributes to various academic debates. It removes the RVB assumptions that resources and capabilities are intrinsically valuable and complementary, and therefore contributes towards making the theory less tautological. It shows how SCG benefits when the effects of supply chain integration and coordination are examined independently. It differentiates between firms lacking willingness and firms lacking capabilities to comply, making it possible to define suitable regulatory strategies for each type of firm. The thesis makes a methodological contribution as it is one of the first studies applying the mvQCA in Science, Technology and Innovations Studies (STIs). The new methodology is used here to test the causal conditions of compliance, but can also be applied to innovative performance more generally. The thesis concludes by showing how US regulations were effective in achieving their regulatory aims without significant negative consequences, and suggesting that STI regulatory policies can be used to increase business engagement to prevent the intentional and accidental contamination of the food chain.

Various commercial software packages are available for simulating compressed air network operations. However, none of these software packages are able to dynamically prioritise compressor selection on large compressed air networks in the mining industry. In this dissertation, a dynamic compressor selector (DCS) will be developed that will actively and continuously monitor system demand. The software will ensure that the most suitable compressors, based on efficiency and position in the compressed air network, are always in operation. The study will be conducted at a platinum mine. Compressed air flow and pressure requirements will be maintained without compromising mine safety procedures. Significant energy savings will be realised. DCS will receive shaft pressure profiles from each of the shafts’ surface compressed air control valves. These parameters will be used to calculate and predict the compressed air demand. All pipe friction losses and leaks will be taken into account to determine the end-point pressure losses at different flow rates. DCS will then prioritise the compressors of the compressed air network based on the overall system requirement. This software combines the benefits of supply-side and demand-side management. Potential energy savings with DCS were proven and compressor cycling reduced. A DCS user-friendly interface was created to easily set up any mine’s compressed air network. / Thesis (MIng (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2013

The aim of this work is to answer questions of effectiveness in controlling inflation, changes in unemployment rate, reduce government spendings, deregulation and decentralization in both countries, confirm or refute theoretical assumptions of Laffer´s curve on the example of consequence of tax cuts in United States of America, privatization and the implications of the fight with the unions in Great Britain and the overall effect of the implementation of neoliberal concepts in both countries. This work compares the implementation and impact of neoliberal concepts of economic policy in the UK and in the United States and it provides insight into the effectiveness of the chosen means.

This thesis investigates overeducation as an aspect of integration among the second generation in Western Europe. As the second generation grows and establishes themselves in the labour market, research about their labour market outcomes becomes increasingly important. Using nine rounds (2002-2018) of the European Social Survey (ESS), this thesis investigates the impact of being a second generation on the probability of being overeducated in Western Europe. An overeducation-measure is developed using the realised matches-approach and weighted linear probability models are performed on pooled and country-stratified samples. The thesis takes into account labour market supply-and demand-side characteristics to discuss possible mechanisms behind the results. The results show that across Western Europe, the second generation faces a higher probability of being overeducated compared to their native counterparts. The UK stands out, where the second generation is subject to an 8,53-percentage point higher probability of being overeducated than the natives. Parental origin and level of education are important supply-side factors, where the second generation with parents from non-EU countries and those with non-tertiary educated parents have higher probabilities of being overeducated. On the demand-side, employment and unemployment protection regulations are associated with overeducation, where stricter employment protection and higher net replacement rates in unemployment is associated with lower probabilities of overeducation among the second generation. This thesis highlights the importance of assessing the labour market supply- and demand-side characteristics in research about labour market outcomes for the second generation, and contributes to the research field with the comparative perspective.

Uninhabited Aircraft Systems (UAS), as a relatively novel technology, was always seen as a tool available and utilized only by rich and developed states. But thanks to globalizations and the fast proliferation of commercially available drones, this platform has already been used by smaller states and also non-state groups, giving them possibilities never seen before. Yet, there is little research on how and why these new actors use UAS to claim their cause. The research question to guide this thesis is how and why do non-state armed groups differ from states when using Uninhabited Aircraft Systems in their military operations? The thesis uses a demand- and supply-side theory, adapted for the proliferation of drones to help answer that question. This theory is tested in a multiple case study involving the United States as a state and the Houthis as a non-state group during the Yemeni crisis, from 2011 to 2022. Through a structured, focused comparison between the cases, indicators from the demand- and supply-side models were used to understand the differences in drone use between different actors. The main findings are that states and non-state armed groups differ in their use of UAS mainly because they have different boundaries (legal and technological), but also for the symbol and status that this platform carries. Finally, it was seen that the theory is not only able to clarify the trends on proliferation, but also the why actors use UAS, with few remarks, but with a need to test it further.
